- Abstract
-
There are many consequences of heart failure (HF), including symptoms, impaired health‐related quality of life (HRQoL), and physical and social limitations (functional status). These have a substantial impact on patients' lives, yet are not routinely captured in clinical trials. Patient‐reported outcomes (PROs) can quantify patients' experiences of their disease and its treatment. Steps can be taken to improve the use of PROs in HF trials, in regulatory and payer decisions, and in patient care. Importantly, PRO measures (PROMs) must be developed with involvement of patients, family members, and caregivers from diverse demographic groups and communities. PRO data collection should become more routine not only in clinical trials but also in clinical practice. This may be facilitated by the use of digital tools and interdisciplinary patient advocacy efforts. There is a need for standardization, not only of the PROM instruments, but also in procedures for analysis, interpretation and reporting PRO data. More work needs to be done to determine the degree of change that is important to patients and that is associated with increased risks of clinical events. This ‘minimal clinically important difference’ requires further research to determine thresholds for different PROMs, to assess consistency across trial populations, and to define standards for improvement that warrant regulatory and reimbursement approvals. PROs are a vital part of patient care and drug development, and more work should be done to ensure that these measures are both reflective of the patient experience and that they are more widely employed.

Background: Profound lymphopenia is an independent predictor of adverse clinical outcomes in sepsis. Interleukin-7 (IL-7) is essential for lymphocyte proliferation and survival. A previous phase II study showed that CYT107, a glycosylated recombinant human IL-7, administered intramuscularly reversed sepsis-induced lymphopenia and improved lymphocyte function. Thepresent study evaluated intravenous administration of CYT107. This prospective, double-blinded, placebo-controlled trial was designed to enroll 40 sepsis patients, randomized 3:1 to CYT107 (10 µg/kg) or placebo, for up to 90 days. Results: Twenty-one patients were enrolled (fifteen CYT107 group, six placebo group) at eight French and two US sites. The study was halted early because three of fifteen patients receiving intravenous CYT107 developed fever and respiratory distress approximately 5–8 h after drug administration. Intravenous administration of CYT107 resulted in a two–threefold increase in absolute lymphocyte counts (including in both CD4+ and CD8+ T cells (all p < 0.05)) compared to placebo. This increase was similar to that seen with intramuscular administration of CYT107, was maintained throughout follow-up, reversed severe lymphopenia and was associated with increase in organ support free days (OSFD). However, intravenous CYT107 produced an approximately 100-fold increase in CYT107 blood concentration compared with intramuscular CYT107. No cytokine storm and no formation of antibodies to CYT107 were observed. Conclusion: Intravenous CYT107 reversed sepsis-induced lymphopenia. However, compared to intramuscular CYT107 administration, it was associated with transient respiratory distress without long-term sequelae. Because of equivalent positive laboratory and clinical responses, more favorable pharmacokinetics, and better patient tolerability, intramuscular administration of CYT107 is preferable.

MEDULLOBLASTOMA, HIPPOCAMPUS (Brain), CHILD patients, VOLUMETRIC-modulated arc therapy, BRAIN tumors, and SUBSTANCE abuse relapse
- Abstract
-
Background: Hippocampal avoidance (HA) has been shown to preserve cognitive function in adult patients with cancer treated with whole‐brain radiation therapy for brain metastases. However, the feasibility of HA in pediatric patients with brain tumors has not been explored because of concerns of increased risk of relapse in the peri‐hippocampal region. Our aim was to determine patterns of recurrence and incidence of peri‐hippocampal relapse in pediatric patients with medulloblastoma (MB). Methods and materials: We identified pediatric patients with MB treated with protons between 2002 and 2016 and who had recurrent disease. To estimate the risk of peri‐hippocampal recurrence, three hippocampal zones (HZs) were delineated corresponding to ≤5 mm (HZ‐1), 6 to 10 mm (HZ‐2), and >10 mm (HZ‐3) distance of the recurrence from the contoured hippocampi. To determine the feasibility of HA, three standard‐risk patients with MB were planned using either volumetric‐modulated arc therapy (VMAT) or intensity‐modulated proton therapy (IMPT) plans. Results: Thirty‐eight patients developed a recurrence at a median of 1.6 years. Of the 25 patients who had magnetic resonance imaging of the recurrence, no patients failed within the hippocampus and only two patients failed within HZ‐1. The crude incidence of peri‐hippocampal failure was 8%. Both HA‐VMAT and HA‐IMPT plans were associated with significantly reduced mean dose to the hippocampi (p <.05). HA‐VMAT and HA‐IMPT plans were associated with decreased percentage of the third and lateral ventricles receiving the prescription craniospinal dose of 23.4 Gy. Conclusions: Peri‐hippocampal failures are uncommon in pediatric patients with MB. Hippocampal avoidance should be evaluated in a prospective cohort of pediatric patients with MB. Plain Language Summary: In this study, the patterns of disease recurrence in patients with a pediatric brain tumor known as medulloblastoma treated with proton radiotherapy were examined. The majority of failures occur outside of an important structure related to memory formation called the hippocampus. Hippocampal sparing radiation plans using proton radiotherapy were generated and showed that dose to the hippocampus was able to be significantly reduced. The study provides the rationale to explore hippocampal sparing in pediatric medulloblastoma in a prospective clinical trial. The incidence of peri‐hippocampal failures in patients treated with proton radiotherapy for pediatric medulloblastoma was 8%.Hippocampal sparing plans were associated with significant reduction in the mean dose to the right and left hippocampi.

Objective This study aimed to determine whether lower values of feature-tracking cardiovascular magnetic resonance (CMR)-derived left atrial reservoir strain (LARS) and impaired left ventricular (LV) global longitudinal strain (GLS) were associated with the presence of symptoms and long-term prognosis in patients with SSc. Methods A total of 100 patients {54 [interquartile range (IQR) 46–64] years, 42% male} with SSc who underwent CMR imaging at two tertiary referral centres were included. All patients underwent analysis of LARS and LV GLS using feature-tracking on CMR and were followed-up for the occurrence of all-cause mortality. Results The median LV GLS was –21.8% and the median LARS was 36%. On multivariable logistic regression, LARS [odds ratio (OR) 0.964 per %, 95% CI 0.929, 0.998, P = 0.049] was independently associated with New York Heart Association (NYHA) class II–IV heart failure symptoms. Over a median follow-up of 37 (21–62) months, a total of 24 (24%) patients died. Univariable Cox regression analysis demonstrated that LARS [hazard ratio (HR) 0.94 per 1%, 95% CI 0.91, 0.97, P < 0.0001) and LV GLS (HR 1.10 per %, 95% CI 1.03, 1.17, P = 0.005) were associated with all-cause mortality, while LV ejection fraction was not. Likelihood ratio tests demonstrated that LARS provided incremental value over prognostically important clinical and imaging parameters, including late gadolinium enhancement. Conclusion In patients with SSc, LARS was independently associated with the presence of NYHA class II–IV heart failure symptoms. Although both LARS and LV GLS were associated with all-cause mortality, only LARS provided incremental value over all evaluated variables known to be prognostically important in patients with SSc.

COVID-19 vaccines, TRANSPLANTATION of organs, tissues, etc., SARS-CoV-2 Omicron variant, IMMUNOGLOBULINS, and DURABILITY
- Abstract
-
Solid organ transplant recipients (SOTRs) have reduced immunogenicity to SARS-CoV-2 vaccines and are at increased risk of severe COVID-19 when compared to the general population.[1] Previously, a fourth dose (D4) of SARS-CoV-2 vaccine has shown improved antibody responses in SOTRs, but given the decreasing titers seen by 6 months post-dose 2 and 3, immune responses achieved after D4 could decrease in a similar fashion.[[2]] This study assesses the durability and kinetics of vaccine-induced antibody responses in SOTRs post-D4 and evaluates these responses in the context of the Omicron variant, which requires higher levels of antibody to neutralize. In this study of antibody responses after a fourth dose of SARS-CoV-2 vaccine in SOTRs with 6 months of follow up, 61% demonstrated antibody titers associated in prior studies with potential SARS-CoV-2 Omicron variant neutralization at 3 months. 3 c 5/18 SOTRs with low titers and 8/39 SOTRs with high titers were unable to provide titers at 3-months post-D4.

Antibody response to a third dose of SARS-CoV-2 vaccine in heart and lung transplant recipients Morbidity and mortality from SARS-CoV-2 infection in heart (HT) and lung transplant (LT) recipients are high, especially for LT recipients, despite vaccination.[1] Despite severe COVID-19 outcomes, HT/LT recipients represent <10% of solid organ transplant recipients (SOTRs) included in cohort studies evaluating two and three dose regimens.[2] There is now strong evidence to support that SOTRs in a greater immunosuppressed state (common among HT/LT recipients) are at increased risk for persistent seronegative state post-D3.[[3]] Therefore, we evaluated antispike antibody responses before and after a third vaccine dose (D3) in HT/LT recipients to quantify post-D3 antibody responses.

TELECOMMUNICATION, CANCER, PRIMARY care, ELECTRONIC health records, and MEDICAL personnel
- Abstract
-
Previous research has identified communication and care coordination problems for patients with cancer. Healthcare providers (HCPs) have reported communication issues due to the incompatibility of electronic medical records (EMR) software and not being consistently copied on patient reports. We evaluated an asynchronous web-based communication system ("eOncoNote") for primary care providers and cancer specialists to improve cancer care coordination. The objectives were to examine patients' perceptions of the role of eOncoNote in their healthcare, and HCPs' experiences of implementing eOncoNote. Qualitative interviews were conducted with patients with breast and prostate cancer, primary care providers, and cancer specialists. Eighteen patients and fourteen HCPs participated. Six themes were identified from the patient interviews focusing on HCP and patient roles related to care coordination and patient awareness of communication among their HCPs. Four themes were identified from HCP interviews related to the context of care coordination and experience with eOncoNote. Both patients and HCPs described the important role patients and caregivers play in care coordination. The results show that patients were often unaware of the communication between their HCPs and assumed they were communicating. HCPs encountered challenges incorporating eOncoNote into their workflow.

Background: The purpose of this article is to describe the development, implementation, and evaluation of a Simulation Interprofessional Education (Sim‐IPE) activity for healthcare students from different disciplines (athletic training [AT] and nursing). The objective for the Sim‐IPE activity was to engage AT and prelicensure nursing students in a realistic healthcare scenario to enhance knowledge about one another's profession, develop interprofessional skills, collaborate with one another, and communicate effectively as a team as they performed care. Methods: This mixed methods study employed a one‐time posttest design for a convenience sample of AT and prelicensure nursing students following a simulation intervention. Students completed the Student Perceptions of Interprofessional Clinical Education‐Revised (SPICE‐R) survey and answered open‐ended response questions. Results: Thirteen students (N = 13) from Cohort 1 and 12 students (N = 12) from Cohort 2 completed the SPICE‐R survey. Most students strongly agreed/agreed for each of the SPICE‐R survey questions. Qualitative findings indicated the students positively perceived the Sim‐IPE activity as it helped them discover the value of interprofessional patient care. Discussion: The quantitative findings indicated that the students found the Sim‐IPE an effective learning methodology to achieve the objectives while the qualitative findings gave further insight into the students' perceptions of interprofessional teamwork and the value of the prebrief session conducted before the simulation. The findings will inform future Sim‐IPE activities involving additional groups of healthcare students. [ABSTRACT FROM AUTHOR]

GENETIC variation, SLEEP, MISSENSE mutation, GENETIC testing, CLOCK genes, SLEEP disorders, and EXOMES
- Abstract
-
Rare variants in ten genes have been reported to cause Mendelian sleep conditions characterised by extreme sleep duration or timing. These include familial natural short sleep (ADRB1, DEC2/BHLHE41, GRM1 and NPSR1), advanced sleep phase (PER2, PER3, CRY2, CSNK1D and TIMELESS) and delayed sleep phase (CRY1). The association of variants in these genes with extreme sleep conditions were usually based on clinically ascertained families, and their effects when identified in the population are unknown. We aimed to determine the effects of these variants on sleep traits in large population-based cohorts. We performed genetic association analysis of variants previously reported to be causal for Mendelian sleep and circadian conditions. Analyses were performed using 191,929 individuals with data on sleep and whole-exome or genome-sequence data from 4 population-based studies: UK Biobank, FINRISK, Health-2000-2001, and the Multi-Ethnic Study of Atherosclerosis (MESA). We identified sleep disorders from self-report, hospital and primary care data. We estimated sleep duration and timing measures from self-report and accelerometery data. We identified carriers for 10 out of 12 previously reported pathogenic variants for 8 of the 10 genes. They ranged in frequency from 1 individual with the variant in CSNK1D to 1,574 individuals with a reported variant in the PER3 gene in the UK Biobank. No carriers for variants reported in NPSR1 or PER2 were identified. We found no association between variants analyzed and extreme sleep or circadian phenotypes. Using sleep timing as a proxy measure for sleep phase, only PER3 and CRY1 variants demonstrated association with earlier and later sleep timing, respectively; however, the magnitude of effect was smaller than previously reported (sleep midpoint ~7 mins earlier and ~5 mins later, respectively). We also performed burden tests of protein truncating (PTVs) or rare missense variants for the 10 genes. Only PTVs in PER2 and PER3 were associated with a relevant trait (for example, 64 individuals with a PTV in PER2 had an odds ratio of 4.4 for being "definitely a morning person", P = 4x10-8; and had a 57-minute earlier midpoint sleep, P = 5x10-7). Our results indicate that previously reported variants for Mendelian sleep and circadian conditions are often not highly penetrant when ascertained incidentally from the general population. Author summary: Clinically ascertained family-based studies have previously identified rare genetic variation associated with causing life-long sleep conditions, specifically shorter sleep, and earlier or later sleep timing. However, the effects of previously reported genetic variants on sleep duration and timing when identified incidentally through population-based studies are not known. Here, we take advantage of up to 191,929 individuals from four population-based studies, including the UK Biobank, to estimate the effects of these variants on sleep duration and timing using self-reported and accelerometer-based sleep estimates coupled with sequencing data. Our analysis revealed no association between variants previously reported and extreme sleep conditions. Two variants located in two genes (PER3 and CRY1) showed evidence of association with sleep timing, but their estimated effects (~5 to 7 minutes) on sleep timing are much smaller relative to those previously reported. Our results indicate that previously reported variants are not causal for extreme sleep conditions in the general population. Finally, although we were unable to analyse a previously reported variant in the PER2 gene associated with sleep timing, additional analysis in the UK Biobank revealed carries of protein-truncating variants in this gene have an approximately 1-hour earlier sleep midpoint compared to non-carriers. These population-based estimates are important because of the recent dramatic increase in direct-to-consumer and health service genome-wide genetic testing. [ABSTRACT FROM AUTHOR]

ALCOHOL drinking, ENERGY consumption, WARNING labels, INCOME, WEIGHT gain, and CONSUMPTION (Economics)
- Abstract
-
Background: Alcohol is a discretionary, energy dense, dietary component. Compared to non-drinkers, people who consume alcohol report higher total energy intake and may be at increased risk of weight gain, overweight, and obesity, which are key preventable risk factors for illness. However, accurate consumer knowledge of the energy content in alcohol is low. To inform future behaviour change interventions among drinkers, this study investigated individual characteristics associated with changing alcohol consumption due to energy-related concerns.Methods: An online survey was undertaken with 801 Australian adult drinkers (18-59 years, 50.2% female), i.e. who consumed alcohol at least monthly. In addition to demographic and health-related characteristics, participants reported past-year alcohol consumption, past-year reductions in alcohol consumption, frequency of harm minimisation strategy use (when consuming alcohol), and frequency of changing alcohol consumption behaviours because of energy-related concerns.Results: When prompted, 62.5% of participants reported changing alcohol consumption for energy-related reasons at least 'sometimes'. Women, those aged 30-44 years, metropolitan residents, those with household income $80,001-120,000, and risky/more frequent drinkers had increased odds of changing consumption because of energy-related concerns, and unemployed respondents had reduced odds.Conclusions: Results indicate that some sociodemographic groups are changing alcohol consumption for energy-related reasons, but others are not, representing an underutilised opportunity for health promotion communication. Further research should investigate whether messaging to increase awareness of alcohol energy content, including through systems-based policy actions such as nutritional/energy product labelling, would motivate reduced consumption across a broader range of drinkers.

TRANSPLANTATION of organs, tissues, etc., COVID-19 vaccines, MESSENGER RNA, VACCINATION, and ANTIBODY formation
- Abstract
-
Heterologous vaccination ("mixing platforms") for the third (D3) dose of SARS‐CoV‐2 vaccine is a potential strategy to improve antibody responses in solid organ transplant recipients (SOTRs), but data are mixed regarding potential differential immunogenicity. We assessed for differences in immunogenicity and tolerability of homologous (BNT162b2 or mRNA‐1273; D3‐mRNA) versus heterologous (Ad.26.COV2.S; D3‐JJ) D3 among 377 SARS‐CoV‐2‐infection naïve SOTRs who remained seronegative after two mRNA vaccines. We measured anti‐spike titers and used weighted Poisson regression to evaluate seroconversion and development of high‐titers, comparing D3‐JJ to D3‐mRNA, at 1‐, 3‐, and 6 month post‐D3. 1‐month post‐D3, seroconversion (63% vs. 52%, p =.3) and development of high‐titers (29% vs. 25%, p =.7) were comparable between D3‐JJ and D3‐mRNA recipients. 3 month post‐D3, D3‐JJ recipients were 1.4‐fold more likely to seroconvert (80% vs. 57%, weighted incidence‐rate‐ratio: wIRR = 1.101.401.77, p =.006) but not more likely to develop high‐titers (27% vs. 22%, wIRR = 0.440.921.93, p =.8). 6 month post‐D3, D3‐JJ recipients were 1.41‐fold more likely to seroconvert (88% vs. 59%, wIRR = 1.04 1.411.93, p =.029) and 2.63‐fold more likely to develop high‐titers (59% vs. 21%, wIRR = 1.382.635.00, p =.003). There was no differential signal in alloimmune events or reactogenicity between platforms. SOTRs without antibody response after two mRNA vaccines may derive benefit from heterologous Ad.26.COV2.S D3. Solid organ transplant recipients with negative anti‐spike antibody after a two‐dose mRNA SARS‐CoV‐2 vaccine series are more likely to seroconvert after receiving a third dose of the heterologous vaccine Ad.26.COV2.S, compared to a homologous mRNA vaccine.

COVID-19 vaccines, TRANSPLANTATION of organs, tissues, etc., IMMUNE response, MESSENGER RNA, and SARS-CoV-2 Delta variant
- Abstract
-
Heterologous vaccination has been explored in small populations of solid organ transplant recipients (SOTRs),1-4 yet 38% of participants had persistently suboptimal response indicating potential role for further vaccine doses.1 The US CDC currently recommends immunocompromised adults who received an Ad26.COV2.S prime to receive one additional dose of SARS-CoV-2 mRNA vaccine, either BNT162b2 or mRNA-1273, followed by two mRNA vaccine boosters, although the efficacy of this strategy in immunocompromised persons is not known. A third dose of SARS-CoV-2 vaccine increases neutralizing antibodies against variants of concern in solid organ transplant recipients. Immunogenicity of Ad26.COV2.S prime and two subsequent doses of mRNA SARS-CoV-2 vaccines in solid organ transplant recipients: A case series. [Extracted from the article]

Background: A better understanding of the extent to which psychosocial and environmental correlates of physical activity are specific to locations would inform intervention optimization. Purpose: To investigate cross-sectional associations of location-general and location-specific variables with physical activity and sedentary time in three common locations adolescents spend time. Methods: Adolescents (N = 472,Mage = 14.1,SD = 1.5) wore an accelerometer and global positioning systems (GPS) tracker and self-reported on psychosocial (e.g., self-efficacy) and environmental (e.g., equipment) factors relevant to physical activity and sedentary time. We categorized each survey item based on whether it was specific to a location to generate psychosocial and environmental indices that were location-general or specific to either school, non-school, or home location. Physical activity (MVPA) and sedentary time were based on time/location match to home, school, or all "other" locations. Mixed-effects models investigated the relation of each index with location-specific activity. Results: The location-general and non-school physical activity psychosocial indices were related to greater MVPA at school and "other" locations. The school physical activity environment index was related to greater MVPA and less sedentary time at school. The home activity environment index was related to greater MVPA at home. The non-school sedentary psychosocial index was related to less sedentary time at home. Interactions among indices revealed adolescents with low support on one index benefited (i.e., exhibited more optimal behavior) from high support on another index (e.g., higher scores on the location-general PA psychosocial index moderated lower scores on the home PA environment index). Concurrent high support on two indices did not provide additional benefit. Conclusions: No psychosocial or environment indices, including location-general indices, were related to activity in all locations. Most of the location-specific indices were associated with activity in the matching location(s). These findings provide preliminary evidence that psychosocial and environmental correlates of activity are location specific. Future studies should further develop location-specific measures and evaluate these constructs and whether interventions may be optimized by targeting location-specific psychosocial and environmental variables across multiple locations.

Mutations in HNF1A cause Maturity Onset Diabetes of the Young (HNF1A-MODY). To understand mechanisms of β-cell dysfunction, we generated stem cell-derived pancreatic endocrine cells with hypomorphic mutations in HNF1A. HNF1A-deficient β-cells display impaired basal and glucose stimulated-insulin secretion, reduced intracellular calcium levels in association with a reduction in CACNA1A expression, and accumulation of abnormal insulin granules in association with SYT13 down-regulation. Knockout of CACNA1A and SYT13 reproduce the relevant phenotypes. In HNF1A deficient β-cells, glibenclamide, a sulfonylurea drug used in the treatment of HNF1A-MODY patients, increases intracellular calcium, and restores insulin secretion. While insulin secretion defects are constitutive in β-cells null for HNF1A, β-cells heterozygous for hypomorphic HNF1A (R200Q) mutations lose the ability to secrete insulin gradually; this phenotype is prevented by correction of the mutation. Our studies illuminate the molecular basis for the efficacy of treatment of HNF1A-MODY with sulfonylureas, and suggest promise for the use of cell therapies. hPSCs model of Maturity Onset Diabetes of the Young caused by mutations in the transcription factor HNF1A (HNF1A-MODY), regulates the expression of genes required for the formation of dense-core insulin granules and calcium-dependent insulin secretion, demonstrating a basis to treat HNF1A-MODY patients with sulfonylureas.

COVID-19 vaccines, TRANSPLANTATION of organs, tissues, etc., VACCINES, and IMMUNE response
- Abstract
-
Fewer than 45% of solid organ transplant recipients (SOTRs) mount a detectable antispike antibody level after two doses of mRNA SARS-CoV-2 vaccination (D2).1 Various vaccination strategies, including mixing platforms, have been proposed, but there is no consensus on the optimal vaccination sequence to improve immunogenicity.2,3 Although using similar technology, the mRNA-1273 vaccine has been associated with higher peak antibody responses than the use of BNT162b2 in immunosuppressed populations, potentially related to a higher vaccine antigen dose.3,4 We therefore studied whether the use of mRNA-1273 versus BNT162b2 as a third primary vaccine dose (D3) might generate a more robust antibody response in SOTR who remained seronegative after two doses of BNT162b2. Improved humoral immunogenicity with mRNA-1273 versus BNT162b2 as third vaccine dose among solid organ transplant recipients seronegative after two BNT162b2 doses METHODS From our national observational study, approved by the Johns Hopkins Institutional Review Board (IRB00248540),4 we included adult SOTRs who tested seronegative after two doses of BNT162b2 and received either a D3-BNT162b2 or D3-mRNA-1273.

Aims This study aimed to examine perceived social norms, the effect of parental drinking on these norms, alcohol use in front of children, and how norms and consumption vary based on child age and gender of the parent. Methods A cross-sectional online panel survey was undertaken with n = 1000 Australian adults (including 670 parents) aged 18–59 years. The survey assessed: alcohol consumption in front of children; normative attitudes towards drinking in the presence of children; and perceived social norms. Results Overall, 33.9% of parents reported drinking a glass of alcohol each day or a couple of times a week, 18.2% reported getting slightly drunk and 7.8% indicated getting visibly drunk each day or a couple of times a week with their children present. In total, 37.5% reported drinking in front of their children at least weekly. Fathers were more likely to drink in front of children than mothers. Most parents deemed drinking small amounts of alcohol in front of children as acceptable but did not accept drunkenness. Respondents were less concerned about a father drinking one or two drinks in front of their children than a mother. Social expectations were not related to child age, but norms related to others' perceived behaviour were. Conclusions Many parents, particularly fathers consume alcohol in front of their children. There is a need to target health promotion strategies to adults and parents consuming in excess of health guidelines, and to the many parents who are consuming alcohol at higher levels in front of their children.

BLACK feminism, HISTORY of feminism, FEMINISM, BLACK feminists, WORLD history, CONVERSATION, and RACISM
- Abstract
-
This roundtable stems from a Zoom event, "New Directions in Feminism and Global Race Studies (a Book Conversation)" with authors Tiffany N. Florvil, Kaiama L. Glover, Annette K. Joseph-Gabriel, Katherine M. Marino, Robin Mitchell, and Jacqueline-Bethel Tchouta Mougoué, hosted by Samantha Pinto. These scholars discussed their recently published books, which expand how we think about transnational feminism and global Black feminisms in the Americas, the Caribbean, Africa, and Europe. The lightly edited transcript of the conversation explores how putting Black women at the center of histories of global feminisms and race studies transforms these fields and the questions that are usually asked. The authors also discussed navigating research challenges and confronting racism in the sources and in the archives. The conversation underscores the importance of intellectual community, as well as the relevance and urgency of Black feminist scholarship today. [ABSTRACT FROM AUTHOR]

TEACHERS, TEACHING of controversial topics, STUDENTS, DISCUSSION in education, and SOCIAL conditions of students
- Abstract
-
Controversial topics may be uncomfortable for teachers to include in their in-class discussions. However, there are considerable cognitive and social-emotional benefits to engagement in controversial conversations, or classroom discussion about controversial topics. It is critical that teachers support students in respectful discussion to help them develop skills such as problem solving, critical thinking, and the ability to consider issues from multiple perspectives. These skills can enable students to meet larger educational goals such as engaged citizenship. The goal of this article is to highlight the benefits of controversial conversations in the classroom and describe teaching approaches that facilitate effective controversial conversations. First, we identify important factors for teachers' consideration in supporting effective and beneficial controversial conversations. Second, we provide examples of topics of conversations that may be appropriate for students of varying ages. Third, we review how the structure of conversation, scaffolding, classroom context, relationships, and students' individual differences can shape controversial conversations. [ABSTRACT FROM AUTHOR]

- Abstract
-
A proof of concept of a novel air microfluidics-enabled soft robotic sleeve to enable lymphedema treatment is presented. Compression sleeves represent the current, suboptimal standard of care, and stationary pumps assist with lymph drainage; however, effective systems that are truly wearable while performing daily activities are very scarce. This problematic trade-off between performance and wearability requires a new solution, which is addressed by an innovative microfluidic device. Its novelty lies in the use of light, small, and inexpensive air microfluidic chips (35 × 20 × 5 mm3 in size) that bring three major advantages compared to their traditional counterparts. First, each chip is designed with 16 fluidic channels with a cross-sectional area varying from 0.04 to 1 mm2, providing sequential inflation and uniform deflation capability to eight air bladders, thereby producing intentional gradient compression to the arm to facilitate lymph fluid circulation. The design is derived from the fundamentals of microfluidics, in particular, hydraulic resistance and paths of least resistance. Second, the air microfluidic chip enables miniaturization of at least eight bulky energy-consuming valves to two miniature solenoid valves for control increasing wearability. Third, the air microfluidic chip has no moving parts, which reduces the noise and energy needed. The cost, simplicity, and scale-up potential of developing methods for making the system are also detailed. The sequential inflation, uniform deflation, and pressure gradient are demonstrated, and the resulted compression and internal air bladder pressure were evaluated. This air microfluidics-enabled sleeve presents tremendous potential toward future improvements in self-care lymphedema management. [ABSTRACT FROM AUTHOR]

COMMUNICABLE diseases, INFECTIOUS arthritis, HOSPITAL patients, CELLULITIS, DRUG abuse, DRUGS, and FISHER exact test
- Abstract
-
Injection drug use poses a public health challenge. Clinical experience indicates that people who inject drugs (PWID) are hospitalized frequently for infectious diseases, but little is known about outcomes when admitted. Charts were identified from local hospitals between 2013–2018 using consultation lists and hospital record searches. Included individuals injected drugs in the past six months and presented with infection. Charts were accessed using the hospital information system, undergoing primary and secondary reviews using Research Electronic Data Capture (REDCap). The Wilcoxon rank-sum test was used for comparisons between outcome categories. Categorical data were summarized as count and frequency, and compared using Fisher's exact test. Of 240 individuals, 33% were admitted to the intensive care unit, 36% underwent surgery, 12% left against medical advice (AMA), and 9% died. Infectious diagnoses included bacteremia (31%), abscess (29%), endocarditis (29%), cellulitis (20%), sepsis (10%), osteomyelitis (9%), septic arthritis (8%), pneumonia (7%), discitis (2%), meningitis/encephalitis (2%), or other (7%). Sixty-six percent had stable housing and 60% had a family physician. Fifty-four percent of patient-initiated discharges were seen in the emergency department within 30 days and 29% were readmitted. PWID are at risk for infections. Understanding their healthcare trajectory is essential to improve their care. [ABSTRACT FROM AUTHOR]

COVID-19, SEDENTARY behavior, PHYSICAL activity, HOSPITAL care, and PATIENTS' attitudes
- Abstract
-
Many patients with COVID-19 experience severe and even fatal disease. Survivors may have long-term health consequences, but data on physical activity and sedentary behaviour are scarce. Therefore, we objectively assessed physical activity (PA) patterns among post-hospitalised patients with COVID-19 and explored associations with patient characteristics, disease severity and cardiac dysfunction. We objectively assessed PA, sedentary behaviour and sleep duration for 24 h/day during 8 days at 3-6 months after COVID-19 hospitalisation. PA and sedentary time were compared across pre-defined subgroups based on patient and disease characteristics, cardiac biomarker release during hospitalisation, abnormal transthoracic echocardiogram at 3-6 months post-hospitalisation and persistence of symptoms post-discharge. PA and sedentary behaviour were assessed in 37 patients (60 ± 10 years old; 78% male). Patients spent 4.2 [3.2; 5.3] h/day light-intensity PA and 1.0 [0.8; 1.4] h/day moderate-to-vigorous intensity PA. Time spent sitting was 9.8 [8.7; 11.2] h/day, which was accumulated in 6 [5; 7] prolonged sitting bouts (≥30 min) and 41 [32; 48] short sitting bouts (<30 min). No differences in PA and sedentary behaviour were found across subgroups, but sleep duration was higher in patients with versus without persistent symptoms (9.1 vs. 8.3 h/day, p = 0.02). Taken together, high levels of sedentary time are common at 3–6 months after COVID-19 hospitalisation, whilst PA and sedentary behaviour are not impacted by patient or disease characteristics.

DISABILITY awareness, PEOPLE with disabilities, CRITICAL thinking, RESEARCH personnel, and STRATEGIC planning
- Abstract
-
Objective: The main objectives were to 1) search and map current disability awareness and training activities in Quebec, Canada, 2) collectively reflect on these practices, and 3) develop a five-year strategic plan.Methods: We used an integrated knowledge translation approach whereby researchers and community partners were involved in all stages. This project consisted of two sequential phases: 1) an environmental scan (web review and interview) of current practices, and 2) a reflection process with an external expert-facilitator in social transformation. Outcome results and process data are reported.Results: We identified 129 activities (71 training, 58 awareness) from 39 organizations (from 123 organizations initially invited). A wide range of characteristics were collected for each activity which allowed for the identification of gaps. The working group met seven times in one year to discuss results from phase 1 and co-create a five-year strategic plan. Main priorities are 1) the development of a methodology for measuring collective impact and 2) content synchronization of activities.Conclusion: Involvement of partners and researchers enabled a concerted and efficient approach to the development of a five-year strategic plan.Practice Implications: A transition committee led by partners will ensure implementation and sustainability of the plan across the province.

ANTIBODY formation, VACCINE effectiveness, HEART transplant recipients, SARS-CoV-2, and MESSENGER RNA
- Abstract
-
While several studies have observed that solid organ transplant recipients experience diminished antibody responses to SARS-CoV-2 mRNA vaccination, data specific to heart and lung transplant (HT/LT) recipients remains sparse. US adult HT and LT recipients completed their vaccine series between January 7 and April 10, 2021. Reactogencity and SARS-CoV-2 anti-spike antibody were assessed after a priming dose (D1) and booster dose (D2). Modified Poisson regression with robust variance estimator was used to evaluate associations between participant characteristics and antibody development. Of 134 heart recipients, there were 38% non-responders (D1-/D2-), 48% booster responders (D1-/D2+), and 14% priming dose responders (D1+/D2+). Of 103 lung recipients, 64% were non-responders, 27% were booster responders, and 9% were priming dose responders. Lung recipients were less likely to develop antibodies (p <.001). Priming dose antibody response was associated with younger recipient age (p =.04), transplant-to-vaccination time ≥6 years (p <.01), and lack of anti-metabolite maintenance immunosuppression (p <.001). Pain at injection site was the most commonly reported reaction (85% after D1, 76% after D2). Serious reactions were rare, the most common being fatigue (2% after D1 and 3% after D2). No serious adverse events were reported. HT and LT recipients experienced diminished antibody response following vaccination; reactogenicity was comparable to that of the general population. LT recipients may exhibit a more impaired antibody response than HT recipients. While current recommendations are to vaccinate eligible candidates and recipients, further studies characterizing the cell-mediated immune response and clinical efficacy of these vaccines in this population are needed.

- Abstract
-
Marketers, filmmakers, and cinema-goers assume that genre has a large effect on how the audience responds to and engages with a film. However, trait measures such as transportability suggest that, in some cases, individual differences may shape audience engagement more than genre does. To investigate this disparity, we compared viewers' enjoyment, identification with characters, and story world absorption (including three subscales: Transportation, Attention, and Emotional Engagement) for film clips from two very different genres (an emotional family film vs. an action chase scene) in a within-subjects design. Across two studies--an exploratory study and a preregistered replication--we found that participants' feelings of being transported into the narrative (a dimension of story world absorption) were more highly correlated across films than other measures were and tended to be less related to genre preference than the other audience response measures were. This pattern of results suggests that feelings of transportation may be more dependent on individual differences, and less sensitive to genre, than other forms of audience response. An exploratory analysis of a short scale measuring trait transportability suggested this measure was not the basis of the individual differences theorized to underlie transportation. Our results further highlight the importance of examining viewer engagement with narrative as a multidimensional, rather than unitary, concept. [ABSTRACT FROM AUTHOR]

COVID-19 pandemic, MEDICAL personnel, PEOPLE with epilepsy, SOCIAL distancing, and CAREGIVER attitudes
- Abstract
-
• The COVID-19 and Epilepsy (COV-E) global surveys were launched in Brazil during the first wave of the pandemic. • People with epilepsy reported worsening seizure control, psychosocial stress, and impaired mental health. • There were difficulties in obtaining drug supplies because of canceled appointments. • Discussion of risk, including SUDEP, was infrequent even before the pandemic. • The surveys remain open to enable new participants to enter data providing insights as the pandemic evolves. The COVID-19 pandemic has had an unprecedented impact on people and healthcare services. The disruption to chronic illnesses, such as epilepsy, may relate to several factors ranging from direct infection to secondary effects from healthcare reorganization and social distancing measures. As part of the COVID-19 and Epilepsy (COV-E) global study, we ascertained the effects of COVID-19 on people with epilepsy in Brazil, based on their perspectives and those of their caregivers. We also evaluated the impact of COVID-19 on the care delivered to people with epilepsy by healthcare workers. We designed separate online surveys for people with epilepsy and their caregivers. A further survey for healthcare workers contained additional assessments of changes to working patterns, productivity, and concerns for those with epilepsy under their care. The Brazilian arm of COV-E initially collected data from May to November 2020 during the country's first wave. We also examined national data to identify the Brazilian states with the highest COVID-19 incidence and related mortality. Lastly, we applied this geographic grouping to our data to explore whether local disease burden played a direct role in difficulties faced by people with epilepsy. Two hundred and forty-one people returned the survey, 20% were individuals with epilepsy (n = 48); 22% were caregivers (n = 53), and 58% were healthcare workers (n = 140). Just under half (43%) of people with epilepsy reported health changes during the pandemic, including worsening seizure control, with specific issues related to stress and impaired mental health. Of respondents prescribed antiseizure medication, 11% reported difficulty taking medication on time due to problems acquiring prescriptions and delayed or canceled medical appointments. Only a small proportion of respondents reported discussing significant epilepsy-related risks in the previous 12 months. Analysis of national COVID-19 data showed a higher disease burden in the states of Sao Paulo and Rio de Janeiro compared to Brazil as a whole. There were, however, no geographic differences observed in survey responses despite variability in the incidence of COVID-19. Our findings suggest that Brazilians with epilepsy have been adversely affected by COVID-19 by factors beyond infection or mortality. Mental health issues and the importance of optimal communication are critical during these difficult times. Healthcare services need to find nuanced approaches and learn from shared international experiences to provide optimal care for people with epilepsy as the direct burden of COVID-19 improves in some countries. In contrast, others face resurgent waves of the pandemic. [ABSTRACT FROM AUTHOR]

Immunosuppression and comorbidities might place solid organ transplant (SOT) recipients at higher risk from COVID‐19, as suggested by recent case series. We compared 45 SOT vs. 2427 non‐SOT patients who were admitted with COVID‐19 to our health‐care system (March 1, 2020 ‐ August 21, 2020), evaluating hospital length‐of‐stay and inpatient mortality using competing‐risks regression. We compared trajectories of WHO COVID‐19 severity scale using mixed‐effects ordinal logistic regression, adjusting for severity score at admission. SOT and non‐SOT patients had comparable age, sex, and race, but SOT recipients were more likely to have diabetes (60% vs. 34%, p <.001), hypertension (69% vs. 44%, p =.001), HIV (7% vs. 1.4%, p =.024), and peripheral vascular disorders (19% vs. 8%, p =.018). There were no statistically significant differences between SOT and non‐SOT in maximum illness severity score (p =.13), length‐of‐stay (sHR: 0.91.11.4, p =.5), or mortality (sHR: 0.10.41.6, p =.19), although the severity score on admission was slightly lower for SOT (median [IQR] 3 [3, 4]) than for non‐SOT (median [IQR] 4 [3–4]) (p =.042) Despite a higher risk profile, SOT recipients had a faster decline in disease severity over time (OR = 0.760.810.86, p <.001) compared with non‐SOT patients. These findings have implications for transplant decision‐making during the COVID‐19 pandemic, and insights about the impact of SARS‐CoV‐2 on immunosuppressed patients. [ABSTRACT FROM AUTHOR]

Background: It is established that Alzheimer's disease (AD) patients experience sleep disruption. However, it remains unknown whether disruption in the quantity, quality or timing of sleep is a risk factor for the onset of AD.Methods: We used the largest published genome-wide association studies of self-reported and accelerometer-measured sleep traits (chronotype, duration, fragmentation, insomnia, daytime napping and daytime sleepiness), and AD. Mendelian randomization (MR) was used to estimate the causal effect of self-reported and accelerometer-measured sleep parameters on AD risk.Results: Overall, there was little evidence to support a causal effect of sleep traits on AD risk. There was some suggestive evidence that self-reported daytime napping was associated with lower AD risk [odds ratio (OR): 0.70, 95% confidence interval (CI): 0.50-0.99). Some other sleep traits (accelerometer-measured 'eveningness' and sleep duration, and self-reported daytime sleepiness) had ORs of a similar magnitude to daytime napping, but were less precisely estimated.Conclusions: Overall, we found very limited evidence to support a causal effect of sleep traits on AD risk. Our findings provide tentative evidence that daytime napping may reduce AD risk. Given that this is the first MR study of multiple self-report and objective sleep traits on AD risk, findings should be replicated using independent samples when such data become available.

COVID-19 pandemic, LIVER transplantation, COVID-19, MEDICAL care, and PANDEMICS
- Abstract
-
COVID‐19 has profoundly affected the American health care system; its effect on the liver transplant (LT) waitlist based on COVID‐19 incidence has not been characterized. Using SRTR data, we compared observed LT waitlist registrations, waitlist mortality, deceased donor LTs (DDLT), and living donor LTs (LDLT) 3/15/2020‐8/31/2020 to expected values based on historical trends 1/2016‐1/2020, stratified by statewide COVID‐19 incidence. Overall, from 3/15 to 4/30, new listings were 11% fewer than expected (IRR = 0.84 0.890.93), LDLTs were 49% fewer (IRR = 0.37 0.510.72), and DDLTs were 9% fewer (IRR = 0.85 0.910.97). In May, new listings were 21% fewer (IRR = 0.74 0.790.84), LDLTs were 42% fewer (IRR = 0.39 0.580.85) and DDLTs were 13% more (IRR = 1.07 1.151.23). Centers in states with the highest incidence 3/15‐4/30 had 59% more waitlist deaths (IRR = 1.09 1.592.32) and 34% fewer DDLTs (IRR = 0.50 0.660.86). By August, waitlist outcomes were occurring at expected rates, except for DDLT (13% more across all incidences). While the early COVID‐affected states endured major transplant practice changes, later in the pandemic the newly COVID‐affected areas were not impacted to the same extent. These results speak to the adaptability of the transplant community in addressing the pandemic and applying new knowledge to patient care. This registry‐based study of liver transplantation in the United States describes the substantial impact of the COVID‐19 pandemic on waitlist events over time and highlights the resiliency of the transplant community.

BIOSIMILARS, DRUG efficacy, PRODUCT safety, PRODUCT reviews, and INFORMATION sharing
- Abstract
-
The World Health Organization (WHO) issued guidelines for the regulatory evaluation of biosimilars in 2009 and has provided considerable effort toward helping member states implement the evaluation principles in the guidelines into their regulatory practices. Despite this effort, a recent WHO survey (conducted in 2019–2020) has revealed four main remaining challenges: unavailable/insufficient reference products in the country; lack of resources; problems with the quality of some biosimilars (and even more with noninnovator products); and difficulties with the practice of interchangeability and naming of biosimilars. The following have been identified as opportunities/solutions for regulatory authorities to deal with the existing challenges: (1) exchange of information on products with other regulatory authorities and accepting foreign licensed and sourced reference products, hence avoiding conducting unnecessary (duplicate) bridging studies; (2) use of a "reliance" concept and/or joint review for the assessment and approval of biosimilars; (3) review and reassessment of the products already approved before the establishment of a regulatory framework for biosimilar approval; and (4) setting appropriate regulatory oversight for good pharmacovigilance, which is essential for the identification of problems with products and establishing the safety and efficacy of interchangeability of biosimilars.

- Abstract
-
Contact lens-related complications are common, affecting around one third of wearers, although most are mild and easily managed. Contact lenses have well-defined anatomical and physiological effects on the ocular surface and can result in other consequences due to the presence of a biologically active material. A contact lens interacts with the tear film, ocular surface, skin, endogenous and environmental microorganisms, components of care solutions and other antigens which may result in disease specific to contact lens wear, such as metabolic or hypersensitivity disorders. Contact lens wear may also modify the epidemiology or pathophysiology of recognised conditions, such as papillary conjunctivitis or microbial keratitis. Wearers may also present with intercurrent disease, meaning concomitant or pre-existing conditions unrelated to contact lens wear, such as allergic eye disease or blepharitis, which may complicate the diagnosis and management of contact lens-related disease. Complications can be grouped into corneal infection (microbial keratitis), corneal inflammation (sterile keratitis), metabolic conditions (epithelial: microcysts, vacuoles, bullae, tight lens syndrome, epithelial oedema; stromal: superficial and deep neovascularisation, stromal oedema [striae/folds], endothelial: blebs, polymegethism/ pleomorphism), mechanical (corneal abrasion, corneal erosion, lens binding, warpage/refractive error changes; superior epithelial arcuate lesion, mucin balls, conjunctival epithelial flaps, ptosis, discomfort), toxic and allergic disorders (papillary conjunctivitis, solution-induced corneal staining, incomplete neutralisation of peroxide, Limbal Stem Cell Deficiency), tear resurfacing disorders/dry eye (contact lens-induced dry eye, Meibomian gland dysfunction, lid wiper epitheliopathy, lid parallel conjunctival folds, inferior closure stain, 3 and 9 o'clock stain, dellen, dimple veil) or contact lens discomfort. This report summarises the best available evidence for the classification, epidemiology, pathophysiology, management and prevention of contact lens-related complications in addition to presenting strategies for optimising contact lens wear.

COVID-19 pandemic, PEOPLE with epilepsy, AT-risk people, EPILEPSY, MEDICAL care, and COVID-19
- Abstract
-
• The COVID-19 and Epilepsy (COV-E) global surveys were launched in May 2020. • UK respondents (n = 463) report changes in seizure frequency, mental health, and sleep. • Discussion of risk, including of SUDEP, was infrequent even before the pandemic. • COVID-19 is having far-reaching consequences on people with epilepsy. • Our study exemplifies the importance of delivering optimal care to mitigate risk. The COVID-19 pandemic has caused global anguish unparalleled in recent times. As cases rise, increased pressure on health services, combined with severe disruption to people's everyday lives, can adversely affect individuals living with chronic illnesses, including people with epilepsy. Stressors related to disruption to healthcare, finances, mental well-being, relationships, schooling, physical activity, and increased isolation could increase seizures and impair epilepsy self-management. We aim to understand the impact that COVID-19 has had on the health and well-being of people with epilepsy focusing on exposure to increased risk of seizures, associated comorbidity, and mortality. We designed two online surveys with one addressing people with epilepsy directly and the second for caregivers to report on behalf of a person with epilepsy. The survey is ongoing and has yielded 463 UK-based responses by the end of September 2020. Forty percent of respondents reported health changes during the pandemic (n = 185). Respondents cited a change in seizures (19%, n = 88), mental health difficulties (34%, n = 161), and sleep disruption (26%, n = 121) as the main reasons. Thirteen percent found it difficult to take medication on time. A third had difficulty accessing medical services (n = 154), with 8% having had an appointment canceled (n = 39). Only a small proportion reported having had discussions about epilepsy-related risks, such as safety precautions (16%, n = 74); mental health (29%, n = 134); sleep (30%, n = 140); and Sudden Unexpected Death in Epilepsy (SUDEP; 15%, n = 69) in the previous 12 months. These findings suggest that people with epilepsy are currently experiencing health changes, coupled with inadequate access to services. Also, there seems to be a history of poor risk communication in the months preceding the pandemic. As the UK witnesses a second COVID-19 wave, those involved in healthcare delivery must ensure optimal care is provided for people with chronic conditions, such as epilepsy, to ensure that avoidable morbidity and mortality is prevented during the pandemic, and beyond.

KIDNEY transplantation, URINARY tract infections, NOSOLOGY, and DIAGNOSIS
- Abstract
-
Infections remain a major threat to successful kidney transplantation (KT). To characterize the landscape and impact of post‐KT infections in the modern era, we used United States Renal Data System (USRDS) data linked to the Scientific Registry of Transplant Recipients (SRTR) to study 141 661 Medicare‐primary kidney transplant recipients from January 1, 1999 to December 31, 2014. Infection diagnoses were ascertained by International Classification of Diseases, Ninth Revision (ICD‐9) codes. The cumulative incidence of a post‐KT infection was 36.9% at 3 months, 53.7% at 1 year, and 78.0% at 5 years. The most common infections were urinary tract infection (UTI; 46.8%) and pneumonia (28.2%). Five‐year mortality for kidney transplant recipients who developed an infection was 24.9% vs 7.9% for those who did not, and 5‐year death‐censored graft failure (DCGF) was 20.6% vs 10.1% (P <.001). This translated to a 2.22‐fold higher mortality risk (adjusted hazard ratio [aHR]: 2.152.222.29, P <.001) and 1.92‐fold higher DCGF risk (aHR: 1.841.911.98, P <.001) for kidney transplant recipients who developed an infection, although the magnitude of this higher risk varied across infection types (for example, 3.11‐fold higher mortality risk for sepsis vs 1.62‐fold for a UTI). Post‐KT infections are common and substantially impact mortality and DCGF, even in the modern era. Kidney transplant recipients at high risk for infections might benefit from enhanced surveillance or follow‐up to mitigate these risks. This national study of kidney transplant recipients shows that infections are common, are associated with approximately twofold increased risk of both mortality and death‐censored graft failure, and thus are still an important driver of posttransplant outcomes.

- Abstract
-
Background: In March 2020, COVID-19 infections began to rise exponentially in the USA, placing substantial burden on the healthcare system. As a result, there was a rapid change in transplant practices and policies, with cessation of most procedures. Our goal was to understand changes to pediatric kidney transplantation (KT) at the national level during the COVID-19 epidemic. Methods: Using SRTR data, we examined changes in pediatric waitlist registration, waitlist removal or inactivation, and deceased donor and living donor (DDKT/LDKT) events during the start of the disease transmission in the USA compared with the same time the previous year. Results: We saw an initial decrease in DDKT and LDKT by 47% and 82% compared with expected events and then a continual increase, with numbers reaching expected prepandemic levels by May 2020. In the early phase of the pandemic, waitlist inactivation and removals due to death or deteriorating condition rose above expected values by 152% and 189%, respectively. There was a statistically significant decrease in new waitlist additions (IRR 0.49 0.65 0.85) and LDKT (IRR 0.17 0.38 0.84) in states with high vs. low COVID activity. Transplant recipients during the pandemic were more likely to have received a DDKT, but had similar calculated panel–reactive antibody (cPRA) values, waitlist time, and cause of kidney failure as before the pandemic. Conclusions: The COVID-19 pandemic initially reduced access to kidney transplantation among pediatric patients in the USA but has not had a sustained effect. [ABSTRACT FROM AUTHOR]

- Abstract
-
In our first survey of transplant centers in March 2020, >75% of kidney and liver programs were either suspended or operating under restrictions. To safely resume transplantation, we must understand the evolving impact of COVID‐19 on transplant recipients and center‐level practices. We therefore conducted a six‐week follow‐up survey May 7‐15, 2020, and linked responses to the COVID‐19 incidence map, with a response rate of 84%. Suspension of live donor transplantation decreased from 72% in March to 30% in May for kidneys and from 68% to 52% for livers. Restrictions/suspension of deceased donor transplantation decreased from 84% to 58% for kidneys and from 73% to 42% for livers. Resuming transplantation at normal capacity was envisioned by 83% of programs by August 2020. Exclusively using local recovery teams for deceased donor procurement was reported by 28%. Respondents reported caring for a total of 1166 COVID‐19–positive transplant recipients; 25% were critically ill. Telemedicine challenges were reported by 81%. There was a lack of consensus regarding management of potential living donors or candidates with SARS‐CoV‐2. Our findings demonstrate persistent heterogeneity in center‐level response to COVID‐19 even as transplant activity resumes, making ongoing national data collection and real‐time analysis critical to inform best practices.

COVID-19 pandemic, KIDNEY transplantation, COVID-19, MACHINE learning, and PANDEMICS
- Abstract
-
Clinical decision‐making in kidney transplant (KT) during the coronavirus disease 2019 (COVID‐19) pandemic is understandably a conundrum: both candidates and recipients may face increased acquisition risks and case fatality rates (CFRs). Given our poor understanding of these risks, many centers have paused or reduced KT activity, yet data to inform such decisions are lacking. To quantify the benefit/harm of KT in this context, we conducted a simulation study of immediate‐KT vs delay‐until‐after‐pandemic for different patient phenotypes under a variety of potential COVID‐19 scenarios. A calculator was implemented (http://www.transplantmodels.com/covid%5fsim), and machine learning approaches were used to evaluate the important aspects of our modeling. Characteristics of the pandemic (acquisition risk, CFR) and length of delay (length of pandemic, waitlist priority when modeling deceased donor KT) had greatest influence on benefit/harm. In most scenarios of COVID‐19 dynamics and patient characteristics, immediate KT provided survival benefit; KT only began showing evidence of harm in scenarios where CFRs were substantially higher for KT recipients (eg, ≥50% fatality) than for waitlist registrants. Our simulations suggest that KT could be beneficial in many centers if local resources allow, and our calculator can help identify patients who would benefit most. Furthermore, as the pandemic evolves, our calculator can update these predictions. This simulation study and interactive online tool model the survival benefit or harm of kidney transplantation in the context of COVID‐19, based on epidemic parameters and individual patient characteristics.

KIDNEY transplantation, COVID-19, COVID-19 pandemic, and EXPECTED returns
- Abstract
-
In March 2020, coronavirus disease 2019 (COVID‐19) spread rapidly nationally, causing widespread emergent changes to the health system. Our goal was to understand the impact of the epidemic on kidney transplantation (KT), at both the national and center levels, accounting statistically for waitlist composition. Using Scientific Registry of Transplant Recipients data, we compared data on observed waitlist registrations, waitlist mortality, and living‐donor and deceased‐donor kidney transplants (LDKT/DDKT) March 15‐April 30, 2020 to expected events calculated from preepidemic data January 2016‐February 2020. There were few changes before March 15, at which point the number of new listings/DDKT/LDKT dropped to 18%/24%/87% below the expected value (all P <.001). Only 12 centers performed LDKT March 15‐31; by April 30, 40 centers had resumed LDKT. The decline in new listings and DDKT was greater among states with higher per capita confirmed COVID‐19 cases. The number of waitlist deaths was 2.2‐fold higher than expected in the 5 states with highest COVID‐19 burden (P <.001). DCD DDKT and regional/national imports declined nationwide but most steeply in states with the highest COVID‐19 burden. The COVID‐19 epidemic has resulted in substantial changes to KT; we must adapt and learn rapidly to continue to provide safe access to transplantation and limit the growing indirect toll of an already deadly disease. The authors present national‐ and center‐level data on reduced kidney transplant activity early in the COVID‐19 pandemic and link findings to state‐level COVID‐19 burden. [ABSTRACT FROM AUTHOR]

Background: Investigation of physical activity and dietary behaviors across locations can inform "setting-specific" health behavior interventions and improve understanding of contextual vulnerabilities to poor health. This study examined how physical activity, sedentary time, and dietary behaviors differed across home, school, and other locations in young adolescents. Methods: Participants were adolescents aged 12–16 years from the Baltimore-Washington, DC and the Seattle areas from a larger cross-sectional study. Participants (n = 472) wore an accelerometer and Global Positioning Systems (GPS) tracker (Mean days = 5.12, SD = 1.62) to collect location-based physical activity and sedentary data. Participants (n = 789) completed 24-h dietary recalls to assess dietary behaviors and eating locations. Spatial analyses were performed to classify daily physical activity, sedentary time patterns, and dietary behaviors by location, categorized as home, school, and "other" locations. Results: Adolescents were least physically active at home (2.5 min/hour of wear time) and school (2.9 min/hour of wear time) compared to "other" locations (5.9 min/hour of wear time). Participants spent a slightly greater proportion of wear time in sedentary time when at school (41 min/hour of wear time) than at home (39 min/hour of wear time), and time in bouts lasting ≥30 min (10 min/hour of wear time) and mean sedentary bout duration (5 min) were highest at school. About 61% of daily energy intake occurred at home, 25% at school, and 14% at "other" locations. Proportionately to energy intake, daily added sugar intake (5 g/100 kcal), fruits and vegetables (0.16 servings/100 kcal), high calorie beverages (0.09 beverages/100 kcal), whole grains (0.04 servings/100 kcal), grams of fiber (0.65 g/100 kcal), and calories of fat (33 kcal/100 kcal) and saturated fat (12 kcal/100 kcal) consumed were nutritionally least favorable at "other" locations. Daily sweet and savory snacks consumed was highest at school (0.14 snacks/100 kcal). Conclusions: Adolescents' health behaviors differed based on the location/environment they were in. Although dietary behaviors were generally more favorable in the home and school locations, physical activity was generally low and sedentary time was higher in these locations. Health behavior interventions that address the multiple locations in which adolescents spend time and use location-specific behavior change strategies should be explored to optimize health behaviors in each location.

ON-site evaluation, STREAMING video & television, VIDEO excerpts, and MEDICAL technology
- Abstract
-
Introduction: Telecytology using real‐time microscopy has gained popularity for rapid on‐site evaluations (ROSE). Although proficiency testing is routinely used in cytopathology, no established means of competency assessment is currently available for telecytology. Our aim was to determine the feasibility of a dynamic (real‐time) platform to assess telecytology competency. Methods: Remote Medical Technology dynamic (real‐time) video streaming platform for ROSE is used at our institution, and short video clips of telecytology cases were recorded using Camtasia Studio 8 software during different ROSE sessions. Selected MP4 videos (range 13‐88 seconds, mean 33 seconds), along with clinical histories, were used to build a multiple‐choice question test with one training case and 20 test cases, utilising Tutor (Philips) software to host the web‐based test. The test was voluntary for cytopathologists and cytotechnologists. Answers and feedback from test takers were analysed. Results: Thirteen participants—four cytopathologists and nine cytotechnologists—previously trained to use telecytology, volunteered to take the test. Individual scores ranged from 10 (50%) to 19 (95%) with a median of 16 (80%). Most feedback received involved technical difficulties. Conclusions: We present, to the best of our knowledge, the first tool to assess telecytology competency for ROSE using pre‐recorded dynamic streaming videos. Despite technical challenges related to incorporating videos into a web‐based test, the test was feasible and provided users with valuable feedback about their ROSE performance. Future effort will be devoted to establishing a more user‐friendly test platform and establishing a benchmark for passing scores. This paper illustrates that an assessment tool for telecytology competency for ROSE using pre‐recorded dynamic streaming videos is feasible. In addition, the novel test provided users with valuable feedback about their ROSE performance and provides feedback on the challenges related to telecytology ROSE. [ABSTRACT FROM AUTHOR]

SCHOOL children, CHILDREN with dyslexia, EMERGENT literacy, PHONOLOGICAL awareness, NOISE, and ARTIFICIAL satellite tracking
- Abstract
-
Humans' propensity to acquire literacy relates to several factors, including the ability to understand speech in noise (SiN). Still, the nature of the relation between reading and SiN perception abilities remains poorly understood. Here, we dissect the interplay between (1) reading abilities, (2) classical behavioral predictors of reading (phonological awareness, phonological memory, and rapid automatized naming), and (3) electrophysiological markers of SiN perception in 99 elementary school children (26 with dyslexia). We demonstrate that, in typical readers, cortical representation of the phrasal content of SiN relates to the degree of development of the lexical (but not sublexical) reading strategy. In contrast, classical behavioral predictors of reading abilities and the ability to benefit from visual speech to represent the syllabic content of SiN account for global reading performance (i.e., speed and accuracy of lexical and sublexical reading). In individuals with dyslexia, we found preserved integration of visual speech information to optimize processing of syntactic information but not to sustain acoustic/phonemic processing. Finally, within children with dyslexia, measures of cortical representation of the phrasal content of SiN were negatively related to reading speed and positively related to the compromise between reading precision and reading speed, potentially owing to compensatory attentional mechanisms. These results clarify the nature of the relation between SiN perception and reading abilities in typical child readers and children with dyslexia and identify novel electrophysiological markers of emergent literacy. Humans' propensity to acquire literacy relates to several factors, one of which is the ability to understand speech in noise. This neuroimaging study reveals that reading abilities and neuronal traces of speech processing in noise are related in multiple specific ways. [ABSTRACT FROM AUTHOR]

Background: Approximately 20.5 million infants were born weighing <2500 g (defined as low birthweight or LBW) in 2015, primarily in low- and middle-income countries (LMICs). Infants born LBW, including those born preterm (<37 weeks gestation), are at increased risk for numerous consequences, including neonatal mortality and morbidity as well as suboptimal health and nutritional status later in life. The objective of this study was to identify predictors of LBW and preterm birth among infants in rural Uganda. Methods: Data were derived from a prospective birth cohort study conducted from 2014–2016 in 12 districts across northern and southwestern Uganda. Birth weights were measured in triplicate to the nearest 0.1 kg by trained enumerators within 72 hours of delivery. Gestational age was calculated from the first day of last menstrual period (LMP). Associations between household, maternal, and infant characteristics and birth outcomes (LBW and preterm birth) were assessed using bivariate and multivariable logistic regression with stepwise, backward selection analyses. Results: Among infants in the study, 4.3% were born LBW (143/3,337), and 19.4% were born preterm (744/3,841). In multivariable analysis, mothers who were taller (>150 cm) (adjusted Odds Ratio (aOR) = 0.42 (95% CI = 0.24, 0.72)), multigravida (aOR = 0.62 (95% CI = 0.39, 0.97)), or with adequate birth spacing (>24 months) (aOR = 0.60 (95% CI = 0.39, 0.92)) had lower odds of delivering a LBW infant Mothers with severe household food insecurity (aOR = 1.84 (95% CI = 1.22, 2.79)) or who tested positive for malaria during pregnancy (aOR = 2.06 (95% CI = 1.10, 3.85)) had higher odds of delivering a LBW infant. In addition, in multivariable analysis, mothers who resided in the Southwest (aOR = 0.64 (95% CI = 0.54, 0.76)), were ≥20 years old (aOR = 0.76 (95% CI = 0.61, 0.94)), with adequate birth spacing (aOR = 0.76 (95% CI = 0.63, 0.93)), or attended ≥4 antenatal care (ANC) visits (aOR = 0.56 (95% CI = 0.47, 0.67)) had lower odds of delivering a preterm infant; mothers who were neither married nor cohabitating (aOR = 1.42 (95% CI = 1.00, 2.00)) or delivered at home (aOR = 1.25 (95% CI = 1.04, 1.51)) had higher odds. Conclusions: In rural Uganda, severe household food insecurity, adolescent pregnancy, inadequate birth spacing, malaria infection, suboptimal ANC attendance, and home delivery represent modifiable risk factors associated with higher rates of LBW and/or preterm birth. Future studies on interventions to address these risk factors may be warranted. [ABSTRACT FROM AUTHOR]

COVID-19, COVID-19 pandemic, KIDNEY transplantation, TRANSPLANTATION of organs, tissues, etc., and INVESTIGATIONAL therapies
- Abstract
-
COVID‐19 is a novel, rapidly changing pandemic: consequently, evidence‐based recommendations in solid organ transplantation (SOT) remain challenging and unclear. To understand the impact on transplant activity across the United States, and center‐level variation in testing, clinical practice, and policies, we conducted a national survey between March 24, 2020 and March 31, 2020 and linked responses to the COVID‐19 incidence map. Response rate was a very high 79.3%, reflecting a strong national priority to better understand COVID‐19. Complete suspension of live donor kidney transplantation was reported by 71.8% and live donor liver by 67.7%. While complete suspension of deceased donor transplantation was less frequent, some restrictions to deceased donor kidney transplantation were reported by 84.0% and deceased donor liver by 73.3%; more stringent restrictions were associated with higher regional incidence of COVID‐19. Shortage of COVID‐19 tests was reported by 42.5%. Respondents reported a total of 148 COVID‐19 recipients from <1 to >10 years posttransplant: 69.6% were kidney recipients, and 25.0% were critically ill. Hydroxychloroquine (HCQ) was used by 78.1% of respondents; azithromycin by 46.9%; tocilizumab by 31.3%, and remdesivir by 25.0%. There is wide heterogeneity in center‐level response across the United States; ongoing national data collection, expert discussion, and clinical studies are critical to informing evidence‐based practices. In this national survey of transplant centers during the COVID‐19 pandemic, the authors report substantial reduction in transplant activity, wide variation in COVID‐19 testing practices, and use of off‐label or investigational therapies in the treatment of 148 COVID‐19‐SOT recipients.

CLOSTRIDIOIDES difficile, GLUTAMATE dehydrogenase, TREATMENT duration, and ENZYME-linked immunosorbent assay
- Abstract
-
A proportion of patients suspected of Clostridium difficile infection are unnecessarily placed in contact isolation. By introducing a random-access glutamate dehydrogenase (GDH) test for C. difficile, we aimed to reduce isolation time. In addition, we investigated whether the result of the toxin A&B enzyme immunoassay (EIA) was associated with the decision to initiate antibiotic treatment against C. difficile. This retrospective pre- and post-implementation study was from June 3, 2016, to June 4, 2018. Pre-implementation, only a NAAT was performed. In the post-implementation period, a GDH test was performed; if positive, a toxin A&B EIA followed the same day and subsequently a NAAT. Contact isolation for CDI was discontinued when the GDH test was negative. Median time in isolation was 50.8 h pre-implementation (n = 189) versus 28.0 h post-implementation (n = 119), p < 0.001. The GDH test had a negative predictive value of 98.8% (95% CI 97.9–99.4). In 7/31 (22.6%) patients with a positive NAAT and GDH test and a negative toxin A&B EIA, no antibiotics against C. difficile were initiated versus 4/28 (14.3%) patients who were NAAT, GDH and toxin A&B EIA positive. Introducing a random-access screening test resulted in a significant decrease in patient isolation time. The GDH test had a high negative predictive value making it suitable to determine whether contact isolation can be discontinued. Furthermore, the result of a toxin A&B EIA had limited added value on the percentage of patients in whom antibiotic treatment against C. difficile was initiated. [ABSTRACT FROM AUTHOR]
