COMMUNICABLE diseases, INFECTIOUS arthritis, HOSPITAL patients, CELLULITIS, DRUG abuse, DRUGS, and FISHER exact test

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]

PATIENT advocacy, EMPATHY, INTERVIEWING, INTERNSHIP programs, UNDERGRADUATES, UNIVERSITIES & colleges, NURSING students, STUDENT attitudes, THEMATIC analysis, and BULLYING

The two aims of this study were, first, to explore nursing students' experiences and perspectives of reporting poor care and second, examine the process by which they raised concerns. The nursing literature is replete with studies which explore nursing students' experiences of clinical placement. However only a small number explore students experiences of challenging poor care and how this is enacted in the practice setting. Fourteen nursing students from undergraduate pre-registration nursing programs across three universities, two in the United Kingdom (UK) and one in Australia. This paper reports findings from narrative interviews about students' clinical experiences of reporting poor care. Data were audio recorded, transcribed verbatim and analyzed using a constant comparison approach. Emerging themes were identified, discussed and verified by the researchers. Four montages from the narratives highlight the overarching themes: bullying, patient advocacy, lack of empathy and poor care. They demonstrate how, driven by an ethical imperative, students speak up when they witness poor care despite the difficulties of doing so: in some cases, the students in this study were prepared to continue speaking out even when initial concerns were dismissed. Both practice and university teams have a responsibility to support students' development as ethical and courageous practitioners, able to recognize when care falls below an acceptable standard. • This paper highlights the vital role that students play in highlighting poor nursing care practices. • Nursing students are capable of reporting poor nursing care even when it might come at a cost to themselves. • Clinicians and academics must support students to challenge poor nursing care practices.

DISABILITY awareness, PEOPLE with social disabilities, PEOPLE with disabilities, CRITICAL thinking, RESEARCH personnel, and STRATEGIC planning

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.

ATMOSPHERIC sulfur compounds, SULFUR deposits, CLIMATE change, GRASSLANDS, and PLANT communities

The predicted long lag time between a decrease in atmospheric deposition and a measured response in vegetation has generally excluded the investigation of vegetation recovery from the impacts of atmospheric deposition. However, policy-makers require such evidence to assess whether policy decisions to reduce emissions will have a positive impact on habitats. Here we have shown that 40 years after the peak of SO x emissions, decreases in SO x are related to significant changes in species richness and cover in Scottish Calcareous, Mestrophic, Nardus and Wet grasslands. Using a survey of vegetation plots across Scotland, first carried out between 1958 and 1987 and resurveyed between 2012 and 2014, we test whether temporal changes in species richness and cover of bryophytes, Cyperaceae, forbs, Poaceae, and Juncaceae can be explained by changes in sulphur and nitrogen deposition, climate and/or grazing intensity, and whether these patterns differ between six grassland habitats: Acid, Calcareous, Lolium , Nardus , Mesotrophic and Wet grasslands. The results indicate that Calcareous, Mesotrophic, Nardus and Wet grasslands in Scotland are starting to recover from the UK peak of SO x deposition in the 1970's. A decline in the cover of grasses, an increase in cover of bryophytes and forbs and the development of a more diverse sward (a reversal of the impacts of increased SO x ) was related to decreased SO x deposition. However there was no evidence of a recovery from SO x deposition in the Acid or Lolium grasslands. Despite a decline in NO x deposition between the two surveys we found no evidence of a reversal of the impacts of increased N deposition. The climate also changed significantly between the two surveys, becoming warmer and wetter. This change in climate was related to significant changes in both the cover and species richness of bryophytes, Cyperaceae, forbs, Poaceae and Juncaceae but the changes differed between habitats.

Background: Increased burden of white‐matter hyperintensities (WMHs) on MRI is common among different types of dementia. WMHs can be caused by various underlying etiologies and are non‐specific markers of tissue abnormality. Therefore, global measures such as WMH burdens may not distinguish between degrees of cognitive impairment. We explored the associations between lobar‐specific WMH volumes and cognitive dysfunction across different dementia subtypes. Method: N=57 participants (7 Alzheimer's disease [AD]/5 subcortical vascular dementia [SVaD]/7 mixed dementia [MixD]/38 vascular cognitive impairment [VCI]; Sex:34M/23F; Age:73±8yrs; pooled from three independent studies) were scanned on 3T MRI. WMHs were segmented on 3D‐FLAIR (MixD/AD/SVaD) or dual‐echo PD/T2‐weighted (VCI) images. T1‐weighted images were processed with Freesurfer 6.0. Left and right frontal, temporal, occipital and parietal lobes plus basal ganglia volumes were constructed using the Freesurfer segmentation outputs. We calculated the proportion of WMH burden within each lobe, i.e. the ratio of lobar WMH volume over the lobar volume. The Montreal Cognitive Assessment (MoCA) was used as a measure of cognitive function. We used a general linear model to determine the association between the WMH/lobar volume ratios and the MoCA scores. Covariates included age, sex, and presence of AD‐related (yes for MixD/AD, no for rest) and vascular‐related conditions (yes for SVaD/VCI/MixD, no for AD). Additionally, we assessed the relationship between the MoCA scores and the ratio of total WMH burden over the whole‐brain parenchymal volume. Result: The model yielded a significant association between the MoCA scores and WMH/lobar ratios within the left (p=0.031) and the right (p=0.035) frontal lobes, with higher ratios predicting lower MoCA scores. The effect was not significant within the temporal, occipital, parietal lobes and the basal ganglia. The effect was insignificant at the whole‐brain level (p=0.08). Conclusion: We found a significant association between the frontal lobe WMH burden and the MoCA scores, especially sensitive to frontal executive functions. This suggests that region‐specific assessments of WMHs may provide improved imaging‐cognitive correlations over the global WMH burden. Future studies with more consistent imaging protocols and broader cognitive/clinical assessments are warranted to further characterize the relationship between WMHs and cognitive impairment.

Background: Alzheimer's disease (AD) with cerebrovascular disease is known as 'mixed' dementia (MixD).[Wang_2012][Langa_2004] MixD can have heterogeneous clinical/imaging presentations. This makes it difficult to distinguish MixD from AD or vascular dementia (VaD) using structural markers such as atrophy or white matter hyperintensity (WMH) volumes. [Suri_2014] We explored whether WM tissue properties on MRI, represented by R2* and diffusion‐tensor (DTI) images, could distinguish MixD from AD or VaD. Method: N=17 participants (cross‐sectional; 7 MixD/5 Subcortical VaD/5 AD; Sex: 11M/6F; Age: 75±8yrs) were scanned on a 3T Philips Achieva. WMHs were segmented on 3D‐Fluid Attenuated Inversion Recovery images. T1‐weighted MP‐RAGE images were segmented into the grey/white‐matters using SPM12. These outputs were combined to construct WMH and normal‐appearing WM (NAWM) masks. DTI images were processed using FSL. R2* images were computed using in‐house software. For each participant, the average R2*, fractional anisotropy (FA) and mean diffusivity (MDf) values were calculated within the WMH and NAWM masks. Result: Average WMH volumes were (mean±SD) AD: 5191±4693mm3, MD: 34680±17059mm3 (p<.05 compared to AD), SVaD: 20896±14920mm3 (p>.05 compared to MixD or AD). A linear model was used to predict the measured R2*, FA or MDf values from the diagnosis subtypes, adjusting for age and sex. R2* results: Pairwise t‐tests revealed significantly lower R2* values within the WMHs compared to NAWM (all subtypes p<0.0005). MixD had significantly lower WMH R2* values compared to AD (p=0.01) or VaD (p=0.02) subgroups. DTI results: Pairwise t‐tests revealed significantly higher MDf values within the WMHs compared to NAWM (all subtypes p<0.009). FA values were significantly lower within the WMHs compared to NAWM for the MixD (p=0.0002) and VaD (p=0.03) but not the AD (p=0.09) subtype. Conclusion: Our MixD cohort was characterized by potentially disrupted fiber integrity (represented by decreased FA) and increased water content (represented by lower R2*) within the WMH areas. These abnormalities likely represent etiologies caused by both neurodegenerative and cerebrovascular factors. Future studies that incorporate measures of neurodegeneration or neuroinflammation, such as biofluid markers, may help to further characterize WM tissue abnormalities in MixD compared to those found in 'pure' AD or VaD.

Background: Vascular dementia (VaD) is often difficult to distinguish from Alzheimer's disease (AD).[O'Brien_2015] Areas of cognitive/clinical decline due to cerebrovascular diseases depend on the frequency and location of the lesions, and may overlap with those found in AD.[Suri_2014] Moreover, AD and cerebrovascular diseases frequently occur simultaneously, leading to heterogeneous 'mixed dementia (MixD)'.[Wang_2012][Langa_2004] It is unclear whether the presence of both neurodegenerative and cerebrovascular pathologies further aggravates dementia‐related imaging abnormalities. We investigated whether the lobar distribution of white matter hyperintensities (WMHs) on MRI differed among AD, VaD and MixD. Method: N=17 participants (cross‐sectional; subtypes:7 MixD/5 Subcortical VaD/5 AD; Sex: 11M/6F; Age: 75±8yrs) were scanned on a 3T Philips Achieva. T1‐weighted MP‐RAGE images were processed with Freesurfer 6.0. Areas of WMHs were segmented on Fluid Attenuated Inversion Recovery (3D‐FLAIR) images using a combination of intensity thresholding and manual correction. Left and right frontal, temporal, occipital and parietal lobes plus basal ganglia volumes were constructed using the Freesurfer segmentation outputs. Individual WMH masks were transformed to their respective T1‐weighted spaces, and the ratios of WMH volumes to different lobar volumes were calculated. Result: Average WMH volumes were (mean±SD) AD: 5191±4693mm3, MixD: 34680±17059mm3 (sig. greater than AD), SVaD: 20896±14920mm3 (n.s. from MixD or AD). We used a linear model to predict the ratios of WMH to lobar volumes from the diagnosis subtypes, adjusting for age and sex. A significant diagnosis‐subtype effect was found in both the left and right frontal lobes. (p=0.012 and 0.045, respectively). In the left frontal lobe, the proportion of WMHs was significantly greater in the MixD subgroup compared to the AD (p=0.0045) or the VaD (p=0.026) subtypes. In the right frontal lobe, the proportion was greater in the MixD subtype compared to the AD (p=0.018) but not compared to VaD (p=0.074) subtype. AD vs. VaD were not significantly different in either sides (p=0.5). Conclusion: The MixD subtype of our pilot study cohort was characterized by a significantly greater presence of WMHs in the frontal lobar areas. Future studies are warranted to investigate the characteristics of underlying tissue abnormalities that could be specific to the diagnosis subtypes. [ABSTRACT FROM AUTHOR]

OCCUPATIONAL therapy, PRIMARY care, MEDICAL rehabilitation, PHYSICAL therapy, and MEDICAL care

Background: Primary healthcare (PHC) is central to increased access and transformation in South African healthcare. There is limited literature about services required by occupational therapists in PHC. Despite policy being in place, the implementation of services at grassroots level does not always occur adequately. Objectives: This study aimed at gaining an understanding of the challenges of being disabled and the services required by occupational therapists (OTs) in rural communities in order to better inform the occupational therapy (OT) training curriculum. Method: An exploratory, descriptive qualitative design was implemented using purposive sampling to recruit 23 community healthcare workers from the uGu district. Snowball sampling was used to recruit 37 members of the uGu community, which included people with disability (PWD) and caregivers of PWDs. Audio-recorded focus groups and semi-structured interviews were used to collect data, which were thematically analysed. Ethical approval was obtained from the Biomedical and Research Ethics Committee of the University of KwaZulu-Natal (BE248/14). Results: Two main themes emerged namely: firstly, the challenges faced by the disabled community and secondly appropriate opportunities for intervention in PHC. A snapshot of the social and physical inaccessibility challenges experienced by the community was created. Challenges included physical and sexual abuse, discrimination and marginalisation. Community-based rehabilitation and ideas for health promotion and prevention were identified as possible strategies for OT intervention. Conclusion: The understanding of the intervention required by OT in PHC was enhanced through obtaining the views of various stakeholders' on the role. This study highlighted the gaps in community-based services that OTs should offer in this context. [ABSTRACT FROM AUTHOR]

Background: Evidence suggests that interleukin (IL)-1β is important in the pathogenesis of atherosclerosis and its complications and that inhibiting IL-1β may favorably affect vascular disease progression.Objectives: The goal of this study was to evaluate the effects of IL-1β inhibition with canakinumab versus placebo on arterial structure and function, determined by magnetic resonance imaging.Methods: Patients (N = 189) with atherosclerotic disease and either type 2 diabetes mellitus or impaired glucose tolerance were randomized to receive placebo (n = 94) or canakinumab 150 mg monthly (n = 95) for 12 months. They underwent magnetic resonance imaging of the carotid arteries and aorta.Results: There were no statistically significant differences between canakinumab compared with placebo in the primary efficacy and safety endpoints. There was no statistically significant change in mean carotid wall area and no effect on aortic distensibility, measured at 3 separate anatomic sites. The change in mean carotid artery wall area was -3.37 mm2 after 12 months with canakinumab versus placebo. High-sensitivity C-reactive protein was significantly reduced by canakinumab compared with placebo at 3 months (geometric mean ratio [GMR]: 0.568; 95% confidence interval [CI]: 0.436 to 0.740; p < 0.0001) and 12 months (GMR: 0.56; 95% CI: 0.414 to 0.758; p = 0.0002). Lipoprotein(a) levels were reduced by canakinumab compared with placebo (-4.30 mg/dl [range: -8.5 to -0.55 mg/dl]; p = 0.025] at 12 months), but triglyceride levels increased (GMR: 1.20; 95% CI: 1.046 to 1.380; p = 0.01). In these patients with type 2 diabetes mellitus or impaired glucose tolerance, canakinumab had no effect compared with placebo on any of the measures assessed by using a standard oral glucose tolerance test.Conclusions: There were no statistically significant effects of canakinumab on measures of vascular structure or function. Canakinumab reduced markers of inflammation (high-sensitivity C-reactive protein and interleukin-6), and there were modest increases in levels of total cholesterol and triglycerides.

Nearly 6.5 million Americans are living with heart failure (HF), the leading cause of hospitalization among adults aged 65 and older. Despite advancements in medical therapy, HF patient outcomes remain of concern. HF readmission rates remain high and only half of patients diagnosed with heart failure are expected to live beyond 5 years of diagnosis. Increasing prevalence and poor outcomes provide significant opportunities for improvement. Hospital participation in a quality initiative designed to improve care by promoting adherence to the scientific guidelines, such as Get With the Guidelines®-Heart Failure (GWTG-HF), assists hospitals in effectively delivering high quality care to improve patient outcomes. The objective of this project is to form multidisciplinary collaboratives that will rapidly implement evidence-based guidelines to develop best practices that can be shared to improve heart failure patient outcomes. The AHA will lead a quality improvement initiative for transforming heart failure care in three major cities including Chicago, Milwaukee and St. Louis. • A retrospective review was conducted using GWTG-HF on measures with low adherence from participating hospitals in the metro markets. • Baseline data of specific HF measures from Quarter 1, 2018 were analyzed and to determine areas of improvement needed. • Using regional and 1:1 hospital meetings, AHA will lead a quality improvement initiative to transform HF patient care. • The HF project will focus on professional education, enhancing systems of care and facilitating the sharing of best practices. • The patient population will include patients from GWTG-HF with a principal/primary diagnosis of heart failure. The project goal within the 2-year timeframe of this initiative is to achieve 20% improvement from baseline data OR achieve AHA's 85% adherence threshold in each measure. AHA Quality staff will observe and monitor market-level data within GWTG-HF to uncover and recommend improvements, provide consultation to clinicians, deliver targeted training and resources such as webinars, conferences, toolkits, care pathways, educational materials and to foster best-practice sharing to address common barriers. Participating hospitals vary in size, discharge volume, GWTG participation tenure, FTE support and resources • *There is incomplete baseline date for the three thirty day follow up measures • Initiative implementation may vary slightly in 3 metro markets The two-year multi-city quality initiative will bring together multiple hospitals to share best practices, develop resources and analyze Get With The Guidelines data for performance improvement to accelerate heart failure patient outcomes. Further investigation is merited evaluating the effectiveness of quality collaboratives to enhance care. [ABSTRACT FROM AUTHOR]

COVID-19, TRANSPLANTATION of organs, tissues, etc., COVID-19 pandemic, SARS-CoV-2, and MEDICAL research

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]

This study explores the perceptions of final year occupational therapy students at the University of KwaZulu Natal and their supervisors, regarding their preparedness to practice as well as their views about the efficacy of the undergraduate curriculum in accomplishing adequate levels of preparedness. Method: A qualitative design using focus groups and semi-structured interviews with students and clinical supervisors to obtain their views and backed up by an analysis of relevant documents of the Health Professions Council of SA and the World Federation of Occupational Therapists, the outcome of which formed the conceptual framework guiding analysis of the data from the interviews and focus groups. Results/findings: Both students and their supervisors felt they possessed adequate graduate competencies to prepare them for practice. Some concerns related to curriculum content, teaching methods, and relationships with lecturers and clinical supervisors emerged. Students’ level of professional confidence was directly influenced by their degree of enjoyment of the fieldwork practical and positive experiences related to this. Supervisors also reported that students display high levels of ethical awareness. Conclusions: the findings provide insights into understanding the relevance of current occupational therapy training specifically at UKZN but also of relevance to the rest of South Africa.
