removable partial dentures, complete dentures, phonetics, awareness, dental students, and dental education

Phonetics plays a major role in the fabrication of prostheses. This study aimed to assess the knowledge of students regarding the role of phonetics in denture fabrication and to improve the educational process and the clinical application. The study was conducted at the College of Dentistry, Imam Abdulrahman Bin Faisal University, and involved a survey of 344 dental students and interns. The questionnaire contained 20 questions and was divided into three sections: general knowledge, clinical correlations, and clinical evaluations. The data were collected and analyzed statistically using independent t-tests, one-way ANOVA, and Tukey’s post hoc tests. The response rate was 100%. Male and female students only differed significantly in terms of their scores for answers to general knowledge questions, with females achieving better results (p = 0.023). General knowledge varied significantly between fourth-year students and all other levels (p < 0.001), and fifth-year students and interns (p = 0.027). The clinical correlations varied significantly between fourth-year students and interns (p = 0.01), whereas the clinical evaluations varied between all the academic years and interns (fourth-year, p < 0.001; fifth-year, p = 0.003; and sixth-year, p = 0.017). The interns obtained the highest scores in all sections. There was a lack of awareness among dental students of some aspects of the role of phonetics in denture fabrication. The study highlights the deficiencies that need to be addressed and the need for adjustments to the curriculum related to removable prosthodontics in order to improve the knowledge of students regarding the role of speech in denture fabrication.

Background: Several studies have demonstrated gender influence on asthma prevalence, being higher among males during early childhood. Little is known about the impact of gender and age on asthma exacerbation characteristics in pediatrics. This study aimed to determine the differences in acute asthma between males and females in three different age groups regarding perinatal characteristics of asthmatic patients, comorbidities, medication adherence, level of blood eosinophils, and pattern of hospitalization.Methods: The medical records of 130 pediatric patients with asthma, who presented to the emergency department at Jordan University hospital with asthma exacerbations, were retrospectively reviewed. Demographic information and clinical characteristics were collected.Results: The mean age of patients was 10.7±4.7 years. The age at diagnosis and gestational age were significantly higher in older children. Furthermore, younger children were significantly more likely to experience winter exacerbations and more emergency presentations. Male patients were considerably younger than their female counterparts and were diagnosed younger. In addition, male patients were more likely to have eosinophil levels higher than 3% than female patients.Conclusion: Gender plays a role in the development and outcome of asthma exacerbations at different ages of pediatrics. A better understanding of gender-based and age-based differences in asthma dictates a personalized approach to treatment.

Education

In this special issue of the Australasian Journal of Educational Technology, we take a step back from the events of the last 2 years and the changes that we have seen in the education arena, to remember that which has remained constant – how students learn best. Developing teaching and learning pedagogy based on lasting education theory and practice makes the past of education relevant to the present and future and creates a context where innovation can be scaled and taken further, from a single instance of impact to many. In this editorial, we present an argument for going back to our roots and present examples of the effective use of established theories of learning that continue to advance online education practice. We discuss the scaling of educational best practice to more students and more institutions, and we provide recommendations for creating sustainable and lasting future practice.

ImportancePatients with dementia may be at an increased suicide risk. Identifying groups at greatest risk of suicide would support targeted risk reduction efforts by clinical dementia services.ObjectivesTo examine the association between a dementia diagnosis and suicide risk in the general population and to identify high-risk subgroups.Design, Setting, and ParticipantsThis was a population-based case-control study in England conducted from January 1, 2001, through December 31, 2019. Data were obtained from multiple linked electronic records from primary care, secondary care, and the Office for National Statistics. Included participants were all patients 15 years or older and registered in the Office for National Statistics in England with a death coded as suicide or open verdict from 2001 to 2019. Up to 40 live control participants per suicide case were randomly matched on primary care practice and suicide date.ExposuresPatients with codes referring to a dementia diagnosis were identified in primary care and secondary care databases.Main Outcomes and MeasuresOdds ratios (ORs) were estimated using conditional logistic regression and adjusted for sex and age at suicide/index date.ResultsFrom the total sample of 594 674 patients, 580 159 (97.6%) were controls (median [IQR] age at death, 81.6[72.0-88.4] years; 289 769 male patients [50.0%]), and 14 515 (2.4%) died by suicide (median [IQR] age at death, 47.4 [36.0-59.7] years; 10 850 male patients [74.8%]). Among those who died by suicide, 95 patients (1.9%) had a recorded dementia diagnosis (median [IQR] age at death, 79.5 [67.1-85.5] years; median [IQR] duration of follow-up, 2.3 [1.0-4.4] years). There was no overall significant association between a dementia diagnosis and suicide risk (adjusted OR, 1.05; 95% CI, 0.85-1.29). However, suicide risk was significantly increased in patients diagnosed with dementia before age 65 years (adjusted OR, 2.82; 95% CI, 1.84-4.33), in the first 3 months after diagnosis (adjusted OR, 2.47; 95% CI, 1.49-4.09), and in patients with dementia and psychiatric comorbidity (adjusted OR, 1.52; 95% CI, 1.21-1.93). In patients younger than 65 years and within 3 months of diagnosis, suicide risk was 6.69 times (95% CI, 1.49-30.12) higher than in patients without dementia.Conclusions and RelevanceDiagnostic and management services for dementia, in both primary and secondary care settings, should target suicide risk assessment to the identified high-risk groups.

Aims In response to pro-fibrotic signals, scleraxis regulates cardiac fibroblast activation in vitro via transcriptional control of key fibrosis genes such as collagen and fibronectin; however, its role in vivo is unknown. The present study assessed the impact of scleraxis loss on fibroblast activation, cardiac fibrosis, and dysfunction in pressure overload-induced heart failure. Methods and results Scleraxis expression was upregulated in the hearts of non-ischemic dilated cardiomyopathy patients, and in mice subjected to pressure overload by transverse aortic constriction (TAC). Tamoxifen-inducible fibroblast-specific scleraxis knockout (Scx-fKO) completely attenuated cardiac fibrosis, and significantly improved cardiac systolic function and ventricular remodelling, following TAC compared to Scx+/+ TAC mice, concomitant with attenuation of fibroblast activation. Scleraxis deletion, after the establishment of cardiac fibrosis, attenuated the further functional decline observed in Scx+/+ mice, with a reduction in cardiac myofibroblasts. Notably, scleraxis knockout reduced pressure overload-induced mortality from 33% to zero, without affecting the degree of cardiac hypertrophy. Scleraxis directly regulated transcription of the myofibroblast marker periostin, and cardiac fibroblasts lacking scleraxis failed to upregulate periostin synthesis and secretion in response to pro-fibrotic transforming growth factor β. Conclusion Scleraxis governs fibroblast activation in pressure overload-induced heart failure, and scleraxis knockout attenuated fibrosis and improved cardiac function and survival. These findings identify scleraxis as a viable target for the development of novel anti-fibrotic treatments.

Background The study’s objective was to analyze the influence of an 8-week neuromuscular electrical stimulation (NMES) with a plyometric (PT) and strength training (ST) program on muscular, sprint, and functional performances in collegiate male football players. Methods Sixty collegiate male football players participated in this randomized controlled trial single-blind study. All the participants were randomly divided into two groups: (1) NMES group (Experimental, n = 30) who received NMES assisted ST and (2) sham NMES group (Control, n = 30) who received sham NMES assisted ST. In addition, participants from both groups received a PT program; both groups received intervention on three days a week for 8-weeks. The study’s outcomes, such as muscular, sprint, and functional performances, were assessed using a strength test (STN) for quadriceps muscle, sprint test (ST), and single-leg triple hop test (SLTHT), respectively, at baseline pre-intervention and 8-week post-intervention. The interaction between group and time was identified using a mixed design (2 × 2) ANOVA. Results Significant difference found across the two time points for the scores of STN: F (1.58) = 5,479.70, p < 0.05; SLTHT: F (1.58) = 118.17, p < 0.05; and ST: F (1.58) = 201.63, p < 0.05. Similarly, the significant differences were found between groups averaged across time for the scores of STN: F (1.58) = 759.62, p < 0.05 and ST: F (1.58) = 10.08, p < 0.05. In addition, after 8-week of training, Cohen’s d observed between two groups a large to medium treatment’s effect size for the outcome STN (d = 10.84) and ST (d = 1.31). However, a small effect size was observed only for the SLTHT (d = 0.613). Conclusions Findings suggest that the effect of PT and ST with either NMES or sham NMES are equally capable of enhancing muscular, sprint, and functional performances in collegiate male football players. However, PT and ST with NMES have shown an advantage over PT and ST with sham NMES in improving muscular performance and sprint performance among the same participants.

Objective To examine the relative risk of suicide mortality in patients with Huntington’s disease (HD). Methods A case–control study design was used. We used linked electronic records from primary care, secondary care and Office for National Statistics from England from 2001 through 2019. Controls were matched to cases by general practice and suicide date. Odds ratios (ORs) were adjusted for gender and age at suicide/index date. Results Data were available for 594,674 individuals. Patients with HD who died from suicide were significantly younger at time of death than patients with HD who died from causes other than suicide (p Conclusion The markedly elevated suicide risk in patients with HD suggests that implementation of suicide risk assessment may improve survival in individuals with these diseases, especially in younger patients.

Education

In response to the special issue on democratizing creative educational experiences (CEE), we conducted a thematic analysis of recent scholarship on creativity and decolonization (2010–2021) and analyzed recurring tensions across literature grounded in Indigenous, Black, feminist, and non-western epistemological perspectives on creativity. We found themes that are not new but are yet to be taken up consistently and credibly in western creativity and education research and practice. For instance, spirituality emerges as a valuable ingredient for creativity, body as inseparable from the mind, dialectic resistance and resilience as acts of creative existence, and non-human agency as essential to the creative process. Informed by these themes, we share implications for research and practice, seeking new spaces inclusive of historically ignored onto-epistemologies.

Given the applied nature of creativity in the arts and design, it is important to understand the conditions and practices that support it. Most research suggests that ideal conditions for creativity are often mental and emotional – involving relaxed, yet alert and focused, states of mind. This article explores the connection between mindfulness and creativity in the experiences of students in a college of arts and design, through a mindfulness teaching practice to support creative processes. In a “scholarship of teaching and learning” inquiry, we consider how mindfulness practice may affect arts and design learners’ feelings about their own creativity. Students in a large United States university school of arts and design practiced mindfulness meditation for several months, and submitted a written reflection on their experience. We qualitatively analyze this to consider how mindfulness supports creative practices in arts and design learners’ education. Our findings involve three key themes, which are: “Processing anxiety and negative feelings”, “Focusing the mind”, and “Managing the ‘Voice of Judgment’”. These thematic findings reflect how arts and design students perceive the effects of mindfulness on their creative process. We offer implications for teaching practices related to mindfulness meditation practice aimed to support learners’ perceptions of their creativity.

The leptin receptor (LepR) acts as a signaling nexus for the regulation of glucose uptake and obesity, among other metabolic responses. The functional role of LepR under leptin-deficient conditions remains unclear. This study reports that epiregulin (EREG) governed glucose uptake in vitro and in vivo in Lepob mice by activating LepR under leptin-deficient conditions. Single and long-term treatment with EREG effectively rescued glucose intolerance in comparative insulin and EREG tolerance tests in Lepob mice. The immunoprecipitation study revealed binding between EREG and LepR in adipose tissue of Lepob mice. EREG/LepR regulated glucose uptake without changes in obesity in Lepob mice via mechanisms, including ERK activation and translocation of GLUT4 to the cell surface. EREG-dependent glucose uptake was abolished in Leprdb mice which supports a key role of LepR in this process. In contrast, inhibition of the canonical epidermal growth factor receptor (EGFR) pathway implicated in other EREG responses, increased glucose uptake. Our data provide a basis for understanding glycemic responses of EREG that are dependent on LepR unlike functions mediated by EGFR, including leptin secretion, thermogenesis, pain, growth, and other responses. The computational analysis identified a conserved amino acid sequence, supporting an evolutionary role of EREG as an alternative LepR ligand.

Increased intracranial pressure is the most common cause of papilledema. Multiple etiologies such as cerebral edema, hydrocephalus, space occupying lesions, infection, and idiopathic intracranial hypertension among others should be considered. Imaging plays a critical role in the detection of pathologies that can cause papilledema. MRI with contrast and CE-MRV, in particular, are key for the diagnosis of idiopathic intracranial hypertension. This review will focus in common and infrequent causes of papilledema, the role of imaging in patients with papilledema as well as its potential mimickers.

This study aims to provide comprehensive insights into the social media marketing characteristics affecting customer buying intention. The model was theoretically based on and explored using a quantitative approach. A survey strategy was adopted, and a five-point Likert questionnaire was distributed to Jordanian citizens. A total of 237 responses were received. The hypothesis testing followed structural equation modeling using SPSS software. The findings suggest that all social media marketing subcontracts exhibit a significant positive effect on buying intention, whereby accessibility is the highest. Customer involvement also moderates the relationship between social media marketing and customer buying intention. The proposed model provides new insights into social media marketing drivers affecting buying intentions and engagement with an entrepreneurial brand or product. This study reaffirms that social media marketing can significantly influence the success of Jordanian entrepreneurial firms and understanding how to use this tool effectively can significantly change how businesses operate.

Objective: Many studied investigated the manifestations of COVID-19, yet few described the pattern and severity of otolaryngological symptoms. We aim to describe the picture of COVID-19-associated otorhinolaryngological manifestations and recovery to explore individualized treatment, onward referral, and complications prevention. Design: Prospective longitudinal questionnaire-based study. Setting: The online questionnaire was filled 3 times through a remote interview over a period of 1 month from June 2020 to July 2020. Participants: Patients with confirmed COVID-19 by RT-PCR who were clinically stable. Main Outcome Measures: Date of diagnosis, sociodemographic data, and the presence of predictive factors, such as nasal and paranasal disease, anosmia and dysgeusia. Validated tools were used, such as Sino-nasal Outcome Test (SNOT-22), smell test (medical academy screening tool), Voice Handicap Index (VHI), and Reflux Symptoms Index (RSI). Result: The questionnaire was sent to 363 patients and the response rate was 70.80% (n = 257). The mean age was 34.58 years (SD = 11.22) and the rate of male participants was 60.7%. The most common otorhinolaryngological symptoms at the time of enrollment was fever (48.6%), whilst the commonest severe symptom was cough (57%). After 1 month, only 11 participants had persistent severe symptoms, especially sleep and psychological symptoms (73%), and the majority were female (63.6%). All of them had at least 1 comorbidity. There was a significant difference between the mean age of participants with severe symptoms (mean = 27.45, SD = 8.39) and without severe symptoms (mean = 34.90, SD = 2.53, t(255) = 2.17, P = .031). Conclusion: COVID-19 has a wide-ranged spectrum of presentations, with otorhinolaryngological symptoms being the commonest and most serious. Studying these symptoms is vital to advance management options.

General Medicine

Introduction: The onset of the COVID-19 pandemic resulted in governments implementing new regulations to divert healthcare resources, which in return led to the postponement of elective and semi-elective surgical procedures. Therefore, many surgeons and as well as surgeons in training reported feeling redundant, which eventually resulted in psychological distress. This study aimed to assess the sociodemographic differences in the psychological impact resulting from the COVID-19 pandemic and outline the effect it had on surgical training. Methods: This is a cross-sectional study conducted in Kuwait. Data were collected by distributing a questionnaire electronically to surgeons and surgeons in training. The survey included questions aimed at assessing both the effect of the pandemic on surgical training and the psychological impact it had on surgeons, assessing the latter using the Depression, Anxiety and Stress Scale-21 screening tool. Results: The response rate for the study was 52%, with the majority being junior male surgeons. A majority of surgeons in training reported postponement of their scheduled academic teaching sessions (78.9%) and pre-assigned surgical rotations (65.8%). In terms of the psychological impact of the pandemic, a majority of the participants reported an element of depression and stress, 61.2% and 55%, respectively, while approximately half, 48.1%, had symptoms associated with anxiety. Conclusion: The COVID-19 pandemic had a negative association with the psychological well-being of a significant proportion of surgeons and associated surgical training programs.

Introduction: Migraine is a highly prevalent condition, and prevalence of obesity is also increasing. Results of studies addressing association of body mass index (BMI) with migraine and its features are conflicting. In this cross-sectional study, we aim to assess association between BMI and various migraine features. Methods: This study was conducted in the Headache Clinic of King Fahd Hospital of University, Al Khobar, Saudi Arabia. Interviews were conducted by three consultant neurologists. Migraine was defined according to the International Headache Society and BMI was calculated as weight (kilograms)/height (m2). Results: Of total of 121 patients, 79% were female. Almost 87.6% of patients were taking prophylactic medications. Majority of patients had attack for more than 24 h (60.3%), pulsating character (81%), moderate-to-severe intensity (92.6%), associated with nausea and/or vomiting (75.2%), and photophobia/phonophobia (91.7%). About 29.8% of patients were normal weight, 28.1% were overweight, and 39.7% were obese and morbidly obese. There was insignificant association between various categories of BMI and features of migraine, that is, unilateral location (P = 0.385), pulsating character (P = 0.571), moderate-to-severe intensity (P = 0.187), nausea and/or vomiting (P = 0.582), and photophobia and/or phonophobia (P = 0.444). Conclusion: In our study, we did not find an association between BMI and various features of migraine.

Background and purpose The objective was to evaluate (1) students' knowledge in a variety of geriatrics competencies, (2) students' attitudes toward the value of interprofessional practice, and (3) pharmacy students' experiences after an advanced pharmacy practice experience (APPE) in a practice-based interprofessional education (IPE) model. Educational activity and setting Nursing, pharmacy, social work, and health sciences programs who participated in the Richmond Health and Wellness Program (RHWP) interprofessional experience received pre- and post-surveys to assess changes in geriatrics knowledge. An adapted Attitude Toward Health Care Teams Scale (ATHCTS) was used to assess changes in students' attitudes toward the value of interprofessional teamwork. Finally, representative quotes were taken from APPE evaluations to illustrate the pharmacy student experience. Findings Seventy-two out of 82 (87.8%) interprofessional students who participated in the practice-based IPE model at RHWP in the fall 2018 participated in this study. Geriatrics knowledge scores significantly increased by 4.03 (P Summary A practice-based IPE experience can provide many benefits to health professional students. By working as a team, students learn from each other, leading to increased knowledge on several geriatrics competencies. Students understand the importance of IPE experiences, but their attitudes become more positive through application.

Refugee children who experience severe pre-migratory adversity often show varying levels of mental health upon resettlement. Thus, it is critical to identify the factors that explain which refugee children experience more vs. less healthy outcomes. The present study assessed child social–emotional capacities (i.e., emotion regulation, sympathy, optimism, and trust) as potential moderators of associations between child, parental, and familial pre-migratory adversities and child mental health (i.e., internalizing and externalizing symptoms) upon resettlement. Participants were N = 123 five- to 12-year-old Syrian refugee children and their mothers living in Canada. Children and mothers reported their pre-migratory adverse life experiences, and mothers reported their children’s current social–emotional capacities, internalizing symptoms, and externalizing symptoms. Greater familial (i.e., the sum of children’s and their mother’s) pre-migratory adversity was associated with higher child internalizing and externalizing symptoms upon resettlement. Higher emotion regulation and optimism were associated with lower internalizing and externalizing symptoms, and higher sympathy was associated with lower externalizing symptoms. In contrast, higher trust was associated with higher internalizing symptoms. Finally, higher child optimism buffered against the positive association between familial pre-migratory adversity and child internalizing symptoms. In sum, select social–emotional capacities may serve as potential protective factors that support mental health and buffer against the deleterious effects of pre-migratory adversity in refugee children.

Up to now, there is no standardized definition for FFT. Therefore, FFT is occasionally mistaken for intraluminal thrombus (ILT) or smooth mural thrombus. The most precise and ideal definition of FFT would be a long-extended intraarterial thrombus that is attached to the arterial wall with its one end, while its other end is surrounded by blood flow and moves freely with the cardiac cycle. FFT usually manifests as an ischemic stroke, thus it is considered as an emergency case. Herein, we report a rare case of symptomatic FFT in the left vertebral artery extending from V0 to V2 segments in a middle-aged smoker, who presented with multiple embolic strokes in different territories of posterior circulation and was successfully treated medically. This case sheds light on the challenges of the clinical approach of FFT in the vertebral artery and it is an attempt to draw attention to the necessity of conducting a large-scale study to find out the ideal approach to manage such conditions.Keywords: stroke, free-floating thrombus, FFT, secondary polycythemia vera, PV, dual antithrombotic

The neurological manifestations of COVID-19 include, but are not limited to, headache, cerebrovascular disease, and skeletal muscle injury.Case Report: Herein, we present a case of stroke with large vessel occlusion in a middle-aged man, who recently recovered from severe SARS-CoV-2 infection. This patient is not known to have any medical illness or surgical history and has no cerebrovascular risk factors. Moreover, the patient underwent extensive investigations, including neuroimaging, cardiac and laboratory work-up with no evidence of stroke etiology.Conclusion: The mechanism of cerebrovascular events in the setting of COVID-19 is still uncertain and probably multi-factorial. The prevailing hypothesis is a strong thrombotic tendency, which may even be prolonged after complete recovery. In our patient’s case, hypercoagulability in the context of viral infection is the most likely mechanism for the stroke. Further studies are needed to find out the exact pathogenesis of thromboembolic events in the setting of COVID-19 infection as well as the efficacy, safety, dosage, and duration of anticoagulants in such conditions.Keywords: large vessel occlusion, stroke, healthy middle-aged, viral hypercoagulability, SARS-CoV-2, independent risk factor

Background/Introduction Despite advances in the diagnosis and management of breast cancer (BC), it is still associated with high mortality rates. New biomarkers are being developed for the diagnosis, treatment, and prediction of responses of BC. Ceramide (CER), a bioactive sphingolipid, has emerged recently as a useful diagnostic tool in several types of tumors. In this study, we evaluated CER expression in invasive BC and assessed its relation to the molecular subtypes of BC. Materials and methods The clinical data and histopathological slides of 50 patients with invasive ductal carcinoma were retrieved and reviewed. The cases were then stained with a mouse monoclonal anti-ceramide antibody. Pearson correlation was used to assess the correlation between CER percentage and intensity and other clinical and pathological variables. Results CER expression showed a direct relationship with estrogen and progesterone receptors Allred scores. However, it showed an inverse relation with tumor grade, HER2/neu status and Ki-67 index. Conclusions CER expression is likely to be associated with luminal BC molecular subtypes. However, more research is needed to confirm these results and to explore its relation to the different clinical outcomes, including response to treatment and prognosis.

As cities adopt mandates to protect, maintain and restore urban biodiversity, the need for urban ecology studies grows. Species-specific information on the effects of urbanization is often a limiting factor in designing and implementing effective biodiversity strategies. In suburban and exurban areas, amphibians play an important social-ecological role between people and their environment and contribute to ecosystem health. Amphibians are vulnerable to threats and imbalances in the aquatic and terrestrial environment due to a biphasic lifestyle, making them excellent indicators of local environmental health. We developed a citizen science program to systematically monitor amphibians in a large city in Alberta, Canada, where 90% of pre-settlement wetlands have been removed and human activities continue to degrade, alter, and/or fragment remaining amphibian habitats. We demonstrate successes and challenges of using publicly collected data in biodiversity monitoring. Through amphibian monitoring, we show how a citizen science program improved ecological knowledge, engaged the public in urban biodiversity monitoring and improved urban design and planning for biodiversity. We outline lessons learned to inform citizen science program design, including the importance of early engagement of decision makers, quality control assessment, assessing tensions in program design for data and public engagement goals, and incorporating conservation messaging into programming.

Enrichment culture (EC) remains gold standard for detecting MRSA colonisation, but molecular methods shorten turnaround time. The CE-marked automated Hologic Panther Fusion MRSA Assay (HPFM) is validated for nasal swabs. We compared HPFM with EC following an in-house PCR for detection of MRSA in nasal, pharyngeal, and perineal ESwabs. The same ESwabs were analysed using HPFM and inoculated in selective Tryptic Soy Broth (TSB) for overnight incubation. TSBs were screened by a PCR targeting nuc, femA, mecA, and mecC. Only samples with PCR results compatible with MRSA presence were inoculated onto 5% blood agar and chromogenic MRSA plates. HPFM detected MRSA in 103 of 132 EC positive samples indicating a sensitivity of 78.0% across sample types. When paired TSBs of 29 EC positive/HPFM negative samples were re-analysed by HPFM, MRSA was detected in 17/29 TSBs indicating that enrichment will increase the sensitivity of HPFM. HPFM analyses of cultured isolates from the remaining 12 EC positive/HPFM negative samples failed to detect orfX. HPFM reported the presence of MRSA in 22 samples where EC failed to identify MRSA. Fifteen of these ESwabs had been kept and direct culture without enrichment identified MRSA in seven samples. HPFM was useful for all sample sites. Compared to EC, the sensitivity of HPFM was limited because of lack of analytical sensitivity and failure to detect all MRSA variants. Failure of some MRSA-containing samples to enrich in cefoxitin-containing TSB indicates an unappreciated limitation of EC, which may lead to underestimation of the specificity of molecular assays.

Background Miller Fisher syndrome (MFS), a triad of ophthalmoplegia, areflexia and ataxia, is one of the regional variants of Guillain-Barre syndrome (GBS) that might account for a quarter of all cases of GBS, especially in Asian countries. There is history of an antecedent upper respiratory tract infection in up to two thirds of MFS cases. However, association of MFS in adults and pneumonia is rarely reported and in those cases causative pathogen was Mycoplasma pneumonia e. To our knowledge, association of MFS and ventilator-associated pneumonia has never been reported. So, we hereby report the first case of MFS which followed ventilator-associated pneumonia (VAP). Case report We report case of a 22-year-old male who was known to have temporal lobe epilepsy and mental retardation. He presented with status epilepticus. He was sedated and put on mechanical ventilation. Two days later, he developed a fever associated with increased tracheobronchial secretions and new infiltrates on chest X-ray. Diagnosis of VAP was made. Upon improvement, he was extubated and shifted out of ICU. Ten days after the onset of fever, he developed gradual onset bulbar weakness and ataxia. On examination, he had generalized areflexia and ataxia. CSF analysis showed cytoalbuminic dissociation. Antibodies against ganglioside complex were elevated. Diagnosis of sero-negative MFS was made, and intravenous immunoglobulin (IVIG) was started. He improved remarkably within two days. Conclusion MFS is immune-mediated entity which is usually triggered by upper respiratory tract infection but in rare cases it can be consequence of pneumonia including VAP. Further research is needed to establish link between MFS and VAP.

Background: Human papillomavirus (HPV) is the most common viral infection of the reproductive tract. This cross-sectional study among female schoolteachers assessed the prevalence of i) unawareness of HPV infection’s causal role in cervical cancer; ii) unawareness of HPV vaccine availability and iii) examined the sociodemographic variables associated both the outcome variables. Methods: This cross-sectional study was conducted among female schoolteachers employed in public and private sectors schools in Kuwait using a structured questionnaire for data collection. Prevalence of each of the outcome variables was computed. Multivariable logistic regression analyses were used to evaluate independent predictors of two dependent variables. Results: A total 1341 female schoolteachers were enrolled. Of the participants, 60% were unaware of HPV causal role in cervical cancer and 88% were unaware of HPV vaccine availability. Among those who were aware of HPV vaccine availability, 83.8% were unvaccinated. Multivariable logistic regression (MLR) model showed that 20–29 years old participants or those with low family income (< 500 KD/month) were significantly (p < 0.05) more likely to be unaware of HPV causal role in cervical cancer. Moreover, participants with family/ personal history of cervical cancer were significantly (p < 0.05) less likely to be unaware of HPV role in causation of cervical cancer. A separate MLR model revealed that the participants were significantly more likely to be unaware of HPV vaccine availability if they were Kuwaiti nationals or non-Kuwaiti Arabs (p < 0.05), employed in public schools (p = 0.003) or less likely to be unaware if they had personal or family history of cervical cancer (p < 0.001). Conclusion: High prevalences of unawareness of causal role of HPV in cervical cancer and unawareness of HPV vaccine availability were recorded. Targeted education among identified sociodemographic groups with high levels of unawareness is warranted. If undertaken, future studies may evaluate the impact of recommended efforts.

Background/Purpose: An innovative care coordination program was developed to enhance wellness among low-income older adults living in subsidized apartment buildings and to provide rich interprofessional education experiences for health professions students. Methods Program effectiveness for the residents was measured through an evaluation of participation, services used, and healthcare utilization. Educational effectiveness was measured through a change in health concepts and perceptions of interprofessional practice. Findings Health care utilization among participating residents showed an 8.6% reduction in emergency department visits and 9.8% reduction in hospital admissions. Students demonstrated improved knowledge in motivational interviewing (p = .02); diabetes (p = .02); hypertension (p≤.01); and frailty (p≤.01). Changes in students perception of interprofessional practice were significant in two areas; Teamwork and Collaboration (p≥.00); and Person Centeredness (p = .00). Discussion This care coordination model may be an effective approach to reduce care resource utilization among medically complex lower income older adults and provides a rich interprofessional learning experience for students.

Aim and Objective: This study aimed to explore how caregivers of persons with Down syndrome (DS) believe caring had an impact on their own lives. A secondary objective was to understand their experience of seeking educational, social, and health care services for the persons with DS. Methods: This qualitative exploratory study was conducted with 21 caregivers of persons with DS in Kuwait. Results: Caregivers struggled to accept the diagnosis initially that led them to search for answers to many of their concerns about raising a person with DS. For the caregivers, who mostly comprised of mothers, dealing with health conditions that persons with DS suffered from was initially difficult. Caring for these individuals led to heavy impact upon their caregivers’ own lives who took extraordinary efforts to cope with the burden. Seeking quality education for the persons with DS and participation in social activities was also challenging, and the caregivers believed that better services, facilities, and benefits for the families of persons with DS may help them better cope with the socioeconomic and psychological burden. Conclusions: Improving the availability of specialized services, the delivery of guidance and counselling, and social integration may help overcome challenges of raising a person with Down Syndrome.

The objective of this study is to provide a reliable roadmap for temporal branch of the facial nerve, in order to minimize, the risk of injury to the nerve during surgical dissections. A literature search was conducted on temporal branch of facial nerve. The date search range was 1950 to 2017. Databases searched included Medline, Web of science, Biosis, SciELO, Data Citation, and Zoologic Records. Data were collected on, author specialty, date of publication, and the relationship of the temporal branch of facial nerve to various landmarks in the frontotemporal region reported in human anatomic studies. Among the 48 studies reviewed, a total of 3477 anatomic dissections were performed in the craniofacial region. Temporal branch of facial nerve was located between 2.5 and 3 cm from lateral orbital rim. In relation to the zygomatic arch, it was found anywhere from the midpoint of the arch to 1 finger breath posterior to the arch. For the plane, it was most commonly described as being under the superficial temporal fascia (STF) or within the loose areolar tissue. Most anatomic dissections found 2 to 4 twigs of the temporal branch of facial nerve. In relation to the lateral canthus, it was found to be 2.85 +/- 0.69 cm superior and 2.54 +/- 0.43 cm lateral to the lateral canthus. Our study suggests consolidated data on surgical landmarks in order to ensure safe dissection in temporal region and prevent injury to the temporal branch of facial nerve.

Creativity emerges in all walks of life and disciplines, requiring diverse approaches and ways of thinking. This article series has taken a wide view to exploring creativity through interviews with experts in different fields (Keenan-Lechel and Henriksen 2019). Beyond disciplinary diversity, it is valuable to think broadly about the types of purposes that creativity relates to. Here, we focus on the work of Dr. Patricia (Pat) Allen, a noted art therapist who uses art and creativity toward mental, emotional, and spiritual wholeness. Her expertise relates to artistic, healing, and therapeutic purposes—and she shares ideas about how education and technology have a role in this. Our conversation offered an illuminating perspective on the role of creativity in healing and wellness, and the education possibilities. We distilled the wide-ranging discussion into themes that include: building systems to support human need; connection to the creative source; rethinking art therapy through the Open Studio Process educational applications for creative wellness; and the affordances of technology for creativity and healing.

The Philippine province of Dinagat Islands supports a huge array of flora and fauna with a high rate of endemism, including three species of mammals found nowhere else in the world. However, anthropogenic activities such as mining are rampant on the island and present a grave threat to the island’s unique biodiversity. We conducted a survey of volant and small non-volant mammals in selected municipalities of Dinagat Islands to contribute to the current understanding of Philippine mammalian fauna. A total of 17 species of volant mammals were recorded among 420 individuals captured in mist nets, 11 species of which are fruit bats and six are insectivorous bats. As for small non-volant mammals, a total of eight species were recorded from 51 individuals captured using a combination of trapping, mist-netting, and transect walks. Among these, eight and six species of volant and non-volant mammals, respectively, were Philippine endemics. We also recorded six species listed under different categories of threat based on the International Union for Conservation of Nature (IUCN) Red List and the Department of Environment and Natural Resources Administrative Order (DENR-DAO). Four species were new records for the Dinagat Islands: Harpionycteris whiteheadi, Rhinolophus subrufus, Pipistrellus javanicus, and Myotis muricola – bringing the total number of recorded mammals on the island to 38 species. With our limited sampling methods, it is possible that some species were overlooked and that new records and novel species may still be discovered as more extensive surveys utilizing other sampling techniques, such as acoustic surveys and the use of different baits and traps, are conducted. Nonetheless, the presence of endemic and threatened species in all our sites – especially those with relatively intact forest – underlines the need for the continued protection of their remaining habitats. Furthermore, our findings emphasize the need for the proper rehabilitation and restoration of areas impacted by mining activities to provide additional habitat and resources for mammals on the island.

Background Characteristics of critical Severe Acute Respiratory Syndrome-related Coronavirus 2 (SARS-CoV-2) infection in children is not well understood. This study described the clinical characteristics of children admitted to intensive care units (ICU) and explored factors associated with the need for invasive ventilation or mortality. Methods A multicenter, retrospective, cohort study was conducted over eight medical centers, including all patients younger than 18 years of age and admitted to the ICU due to a direct consequence of coronavirus disease 2019 (COVID-19). Patients who were admitted to the ICU for any alternate reason and tested positive for SARS-CoV-2 by screening test, and patients who were admitted due to multi-inflammatory syndrome in children, were excluded. Demographic, laboratory, imaging, and clinical data were collected. Descriptive statistics were used to compare survivors and non-survivors. Fine and Gray’s hazard model was used to estimate the association between clinical variables and ICU death. Results During the study period, 25 pediatric COVID-19 patients received care in the ICUs. The median age was 2.78 years (IQR 0.21–8.51), and 60% were male. Only three patients were reported to be previously healthy at admission. Nine (36%) patients required invasive mechanical ventilation, including two were on extracorporeal membrane oxygenation. Four (16%) patients died during ICU care. In univariate analysis, the presence of comorbidity (HR 0.0001; 95%CI 0.00001–0.00016), platelets count (HR 0.99; 95% CI 0.98–0.99), elevated procalcitonin (HR 1.05; 95%CI 1.016–1.09), and circulatory compromise (HR 16.34; 95%CI 1.99–134.35), all at the time of ICU admission, were associated with in-ICU mortality. Conclusion Our findings suggest that children admitted to the ICU with SARS-CoV-2 infection, generally, have a favorable outcome. Low platelets count, elevated procalcitonin, presence of comorbidity, and shock at the time of ICU admission were associated with death. This study may shed more light on the disease dynamics of critical pediatric COVID-19.

Although most cases of jugular bulb diverticulum are asymptomatic, excessive pressure on the surrounding structures might cause various symptoms, most prominently vertigo, sensorineural hearing loss, or tinnitus.Case Report: A middle-aged male who was referred to the Department of Neurology with a recurrent complaint of left-sided facial weakness associated with headache and vertigo for a period of 24 months. His symptoms were episodic, furthermore exacerbated by visiting high altitude sites. Non-resolving with conventional medical treatment. After thorough investigation, including preoperative and postoperative audiograms, neuroimaging, including computed tomography as well as magnetic resonance angiography, he was diagnosed to have right-sided superior mega jugular bulb as a causative factor. After surgical management, the patient improved significantly. At his regular follow-up in our clinic there were no exacerbations of his symptoms.Conclusion: Among patients who present with recurrent non-resolving facial palsy in which no apparent causative factor is identified, high jugular bulb should be suspected and investigated. Comprehensive and detailed medical history is essential for raising the suspicion for the diagnosis. Such as the case presented eliciting high altitudes as the main precipitating factor. The diagnosis is clinically elusive, commonly obscured by other common diagnoses. Surgery is recommended if antihypertensive drugs do not show improvement.Keywords: internal jugular vein, high jugular bulb, facial nerve palsy, high jugular bulb dehiscence, headache, surgery

2020 has been an extremely difficult and challenging year as a result of the coronavirus disease 2019 (COVID-19) pandemic and one in which most efforts have been channeled into tackling the global health crisis. The US Food and Drug Administration (FDA) has approved 53 new drug entities, six of which fall in the peptides and oligonucleotides (TIDES) category. The number of authorizations for these kinds of drugs has been similar to that of previous years, thereby reflecting the consolidation of the TIDES market. Here, the TIDES approved in 2020 are analyzed in terms of chemical structure, medical target, mode of action, and adverse effects.

Internationally, creativity is a widely discussed construct that is pivotal to educational practice and curriculum. It is often situated alongside technology as a key component of education futures. Despite the enthusiasm for integrating creativity with technologies in classrooms, there is a lack of common ground within and between disciplines and research about how creativity relates to technology in teaching and learning—especially in the uncertain space of classroom implementation. This article provides a critical thematic review of international literature on creativity and technology in the context of educational practice. We identify four essential domains that emerge from the literature and represent these in a conceptual model, based around: (1) Learning in regard to creativity, (2) Meanings of creativity, (3) Discourses that surround creativity, and (4) the Futures or impacts on creativity and education. Each of these clusters is contextualized in regard to emerging technologies and the developing scope of twenty-first century skills in classroom implementation. We offer conclusions and implications for research and practice.

Abstract ContextRoad mitigation to reduce animal–vehicle collisions (AVCs) is usually based on analysis of road survey animal carcass data. This is used to identify road sections with high AVC clusters. Large mammals that are struck and die away from a road are not recorded nor considered in these analyses, reducing our understanding of the number of AVCs and the cost–benefit of road mitigation measures. AimsOur aim was to develop a method to calculate a correction factor for large mammal carcass data reported through road survey. This will improve our understanding of the magnitude and cost of AVCs. MethodCitizen scientists reported animal carcasses on walking surveys along transects parallel to the highway and reported observations using a smartphone application at three sites over a 5-year period. These data were compared with traditional road survey data. Key resultWe found that many large mammals involved in AVCs die away from the road and are, therefore, not reported in traditional road surveys. A correction factor of 2.8 for our region can be applied to road survey data to account for injury bias error in road survey carcass data. ConclusionsFor large mammals, AVCs based on road survey carcass data are underestimates. To improve information about AVCs where little is known, we recommend conducting similar research to identify a correction factor to conventionally collected road survey carcass data. ImplicationsIdentifying road mitigation sites by transportation agencies tends to focus on road sections with above-threshold AVC numbers and where cost–benefit analyses deem mitigation necessary. A correction factor improves AVC estimate accuracy, improving the identification of sites appropriate for mitigation, and, ultimately, benefitting people and wildlife by reducing risks of AVCs.

This paper is based upon the closing keynote presentation that was given by danah boyd at the inaugural NISO Plus conference held from February 23–25, 2020 in Baltimore, MD (USA). It focuses on how data are used, and how they can be manipulated to meet specific objectives – both good and bad. The paper reinforces the importance of understanding the biases and limitations of any data set. Topics covered include data quality, data voids, data infrastructures, alternative facts, and agnotology. The paper stresses that data become legitimate because we collectively believe that those data are sound, valid, and fit for use. This not only means that there is power in collecting and disseminating data, but also that there is power in interpreting and manipulating the data. The struggle over data’s legitimacy says more about our society – and our values – than it says about the data itself.

Background. Detachment of acrylic teeth from denture base material is a common complication in dentistry which accounts for 26–30% of repair cases. This study aimed to evaluate the effect of alumina-blasting, silane coupling agent, and thermal cycling on the shear bond strength of repaired teeth to denture base. Materials and Methods. Specimens (140) of repaired teeth to denture bases were fabricated and divided into 14 groups: 7 groups before thermal cycling and 7 groups after thermal cycling (n = 10). The groups were divided according to surface treatment into no treatment (control), treatment of the base (B), the tooth (T), or both (BT). Each group was further subdivided according to the surface treatment method into alumina-blasting or alumina-blasting and silane coupling agent. After treatment, acrylic discs and teeth were fixed in a jig, and the repair procedure was done. Half the specimens were thermally cycled. Shear bond strength was measured using a universal testing machine. ANOVA and Tukey HSD tests were performed at α = 0.05. Results. Surface treatment significantly improved the bond strength compared to the control group P < 0.001 . Comparing surface treatments, alumina-blasting with silane coupling agent treatment resulted in significantly higher strength compared to alumina-blasting alone P < 0.001 . The BT group treated with alumina-blasting and silane coupling agent showed the highest significant shear bond strength (23.91 ± 0.96 MPa) P < 0.001 . Significant drop in strength value was observed in all groups after thermal cycling P < 0.004 except the BT group treated with alumina-blasting P = 0.096 . Conclusion. Surface treatment using alumina-blasting with silane coupling agent for denture base and tooth increased repair strength.
