Authors: Popov Nadejda , Mercier Leah J. , King Regan , Fung Tak , Debert Chantel T. 
Published: March 2021

ABSTRACT:Objective:To assess demographic, clinical, and injury characteristics associated with health-related quality of life (HRQOL) in adults with persistent post-concussion symptoms (PPCS).Methods:Adults with PPCS presenting to a specialized brain injury clinic completed demographic, injury, and clinical outcome questionnaires at the initial clinic assessment. Clinical outcome measures were collected including the Rivermead Post-Concussion Symptoms Questionnaire (RPQ), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale-7 (GAD-7), and the Fatigue Severity Scale (FSS). HRQOL was measured using the Quality of Life after Brain Injury (QOLIBRI) questionnaire. Stepwise hierarchical multiple regression analysis adjusting for age, sex, and months since injury was used to determine associations between quality of life and clinical outcome measures.Results:Overall, 125 participants were included. The PHQ-9, FSS, and GAD-7 were significant predictors of QOLIBRI scores (R2= 0.481, p < .001), indicating that participants with higher levels of depressive symptoms, fatigue, and anxiety reported poorer HRQOL. The PHQ-9 score was the strongest predictor, accounting for 42.0% of the variance in QOLIBRI scores. No demographic or injury characteristics significantly predicted QOLIBRI scores. There was a high prevalence of depressive symptoms with 72.8% of participants having PHQ-9 scores ≥ 10.Conclusion:Among patients with PPCS, mental health and fatigue are important contributors to HRQOL. As there is a high burden of mood disorders and fatigue in this population, targeted treatments for these concerns may impact the quality of life.

Published: March 2021

ABSTRACT:Background:The effect of hormonal therapy has been extensively studied in women. However, similar data on male-to-female (MTF) transgenders, another important population that receives hormonal therapy is lacking. Existing studies in MTF transgenders are skewed toward mental health and health-harming behaviors while few have focused on chronic health conditions. Our study aims to review the existing data on stroke in MTF transgenders and perform a quantitative analysis on the frequency of this condition in this special population.Methods:PubMed, Cochrane, Scopus, Embase, ClinicalTrials.gov, and Web of Science were systematically searched for studies that reported data on the occurrence of cerebrovascular diseases in MTF transgenders. We reported the hormonal regimens, clinical characteristics, and outcomes of stroke in MTF transgenders. A meta-analysis of proportions was performed by the random-effects model to compute for the frequency of cerebrovascular events in MTF transgenders.Results:Fourteen studies were included in the qualitative analysis while five studies were included in the quantitative analysis. A total of 109 MTF transgenders (Mean 14; range 1–53) suffered a cerebrovascular event. Random-effect modeling analysis showed an overall estimated frequency of 2% for cerebrovascular events in transgenders with a moderate degree of heterogeneity (I2 = 62%).Conclusion:Hormonal therapy in MTF transgenders may confer cardiovascular risks in this population. However, more population-based studies that include clinical characteristics and outcomes of chronic health diseases in MTF transgenders are warranted. Such studies may be crucial in directing future guidelines on the health care and management of MTF transgenders.
Is It Time to Consider Implementation of Telemedicine in Current Oral Health Care Services?
Authors: Ilhan Betul , Bayrakdar Ibrahim Sevki , Baydar Oguzhan , Guneri Pelin 
Published: March 2021

AbstractTelemedicine offers an excellent opportunity to provide continuing health care for those in need during local/global pandemics and disasters. It provides a safe and effective communication tool between health professionals and can be used as “forward triage” to manage medical/dental emergencies and to minimize the contact between the patients and clinicians during the coronavirus disease (COVID-19) pandemic. Patients with noncommunicable diseases, like cancer, diabetes, cardiovascular, or chronic respiratory diseases, may present with critical health problems due to less access to health care systems during global disasters; opportunities for screening oral mucosa might be significantly disrupted, leading to delayed diagnosis of malignant/potentially malignant lesions. Telemedicine and oral health care associated mobile applications should be implemented to provide equal access to care, to eliminate unnecessary visits to health centers, and to improve practical coordination between professionals and health facilities.
The Perception of the Legitimacy of Citizens’ Assemblies in Deeply Divided Places? Evidence of Public and Elite Opinion from Consociational Northern Ireland

Published: March 2021

AbstractHow much public and elite support is there for the use of a citizens’ assembly – a random selection of citizens brought together to consider a policy issue – to tackle major, deadlock-inducing disagreements in deeply divided places with consociational political institutions? We focus on Northern Ireland and use evidence from a cross-sectional attitude survey, a survey-based experiment and elite interviews. We find that the general public support decision-making by a citizens’ assembly, even when the decision reached is one they personally disagree with. However, support is lower among those with strong ideological views. We also find that elected politicians oppose delegating decision-making power to an ‘undemocratic’ citizens’ assembly, but are more supportive of recommendation-making power. These findings highlight the potential for post-conflict consociations to be amended, with the consent of the parties, to include citizens’ assemblies that make recommendations but not binding policy.
Ice thickness estimates of Lemon Creek Glacier, Alaska, from active-source seismic imaging

Published: March 2021

AbstractLemon Creek Glacier, a temperate valley glacier in the Juneau Icefield of Southeast Alaska, is the site of long running (>60 years) glaciological studies. However, the most recent published estimates of its thickness and subglacial topography come from two ~50 years old sources that are not in agreement and do not account for the effects of years of negative mass balance. We collected a 1-km long active-source seismic line on the upper section of the glacier parallel and near to the centerline of the glacier, roughly straddling the equilibrium-line altitude. We used these data to perform joint reflection-refraction velocity modeling and reflection imaging of the glacier bed. We find that this upper section of Lemon Creek Glacier is as much as 150 m (~65%) thicker than previously suggested with a large overdeepening in an area previously believed to have a uniform thickness. Our results lead us to reinterpret the impact of basal motion on ice flow and have a significant impact on expectations of subglacial hydrology. We suggest that further efforts to develop a whole-glacier model of subglacial topography are necessary to support studies that require accurate models of ice thickness and subglacial topography.

Published: March 2021

AbstractObjectivePractices vary regarding the timing of discharge after sinonasal surgery. This study aimed to examine the cost-effectiveness of same-day discharge compared to next-day discharge after sinonasal surgery.MethodsA retrospective single-surgeon audit of sinonasal surgery over a 12-month period was performed. Demographic and clinical details, including distance travelled home, timing of discharge, hospital re-presentation, and complications, were collected and compared between the same-day discharge and next-day discharge groups. A cost-effectiveness analysis was performed.ResultsA total of 181 patients were identified; 117 underwent day-case surgery, of which 6 re-presented to the emergency department. Sixty-four patients stayed overnight after surgery, and six of those patients re-presented to the emergency department. The per patient cost was $3262 for day-case sinonasal surgery and $5050 for those admitted overnight after surgery (p < 0.001).ConclusionRoutine same-day discharge after sinonasal surgery is achievable, safe and cost-effective.

AbstractBackgroundThis study examined the efficacy of attention bias modification training (ABMT) for the treatment of depression.MethodsIn this randomized clinical trial, 145 adults (77% female, 62% white) with at least moderate depression severity [i.e. self-reported Quick Inventory of Depressive Symptomatology (QIDS-SR) ⩾13] and a negative attention bias were randomized to active ABMT, sham ABMT, or assessments only. The training consisted of two in-clinic and three (brief) at-home ABMT sessions per week for 4 weeks (2224 training trials total). The pre-registered primary outcome was change in QIDS-SR. Secondary outcomes were the 17-item Hamilton Depression Rating Scale (HRSD) and anhedonic depression and anxious arousal from the Mood and Anxiety Symptom Questionnaire (MASQ). Primary and secondary outcomes were administered at baseline and four weekly assessments during ABMT.ResultsIntent-to-treat analyses indicated that, relative to assessment-only, active ABMT significantly reduced QIDS-SR and HRSD scores by an additional 0.62 ± 0.23 (p = 0.008, d = −0.57) and 0.74 ± 0.31 (p = 0.021, d = −0.49) points per week. Similar results were observed for active v. sham ABMT: a greater symptom reduction of 0.44 ± 0.24 QIDS-SR (p = 0.067, d = −0.41) and 0.69 ± 0.32 HRSD (p = 0.033, d = −0.42) points per week. Sham ABMT did not significantly differ from the assessment-only condition. No significant differences were observed for the MASQ scales.ConclusionDepressed individuals with at least modest negative attentional bias benefitted from active ABMT.

abstractDo online social networks affect political tolerance in the highly polarized climate of postcoup Egypt? Taking advantage of the real-time networked structure of Twitter data, the authors find that not only is greater network diversity associated with lower levels of intolerance, but also that longer exposure to a diverse network is linked to less expression of intolerance over time. The authors find that this relationship persists in both elite and non-elite diverse networks. Exploring the mechanisms by which network diversity might affect tolerance, the authors offer suggestive evidence that social norms in online networks may shape individuals’ propensity to publicly express intolerant attitudes. The findings contribute to the political tolerance literature and enrich the ongoing debate over the relationship between online echo chambers and political attitudes and behavior by providing new insights from a repressive authoritarian context.
Experiences of loneliness among older people living alone. A qualitative study in Quebec (Canada)
Authors: Charpentier Michèle , Kirouac Laurie 
Published: March 2021

AbstractIn this article, we analyse experiences of loneliness among older people living alone. Current knowledge suggests that loneliness is a significant social issue that can compromise health and wellbeing, and that seniors living alone are at a higher risk of loneliness. Based on a qualitative methodological approach and semi-structured interviews conducted with 43 people aged 65 or over living alone in Montreal (Quebec, Canada), this study sought to understand how they perceive, reflect on and react to loneliness. The results show that these seniors perceive loneliness as a dynamic, and rarely static, experience, which has a very different significance, depending on whether it is chosen or circumstantially imposed. The experience of loneliness recounted by the seniors we met is characterised by its heterogeneity, and involves, to varying degrees, their relationship to themselves (solitude), to others (family (and friends) lonelinessandloneliness in love) and/or to the world (existential lonelinessandaloneness). Lastly, our analyses highlight how social factors, such as age, gender, marital status, social network and socio-economic conditions, shape the experience of loneliness among seniors. These factors also influence the strategies that seniors develop to prevent or alleviate loneliness, strategies that yield very mixed results.

AbstractObjective:Food security status is a continuum ranging from high to very low food security. While marginal food security falls next to high food security on the spectrum, new quantitative research indicates marginal food security status is associated with negative health outcomes and poor academic performance among college students. Qualitative research focusing on college students experiencing marginal food security has not been conducted. The current study aims to qualitatively explore experiences of college students with marginal food security and to identify themes to better understand and provide context regarding how marginal food security impacts students.Design:Students were recruited for semi-structured interviews with questions designed to study the challenges associated with students’ food situations. All interviews were recorded and transcribed with themes identified via an inductive approach.Setting:A large public university on the US west coast.Participants:Thirty college students.Results:Key themes that emerged: purchasing cheap unhealthy foods, insufficient time to prepare and eat meals on a regular basis, stress and anxiety around the inability to eat healthy food and future health issues, self-perception of health when eating poorly along with physical symptoms and low academic motivation by not fully participating in their courses due to few healthy food options or missing meals.Conclusion:Marginal food security can potentially diminish students’ health and their capacity to learn and succeed in their coursework. The results emphasise that students experiencing marginal food security should not be grouped with students experiencing high food security.
Pellagra in South Africa from 1897 to 2019: a scoping review
Authors: Viljoen Margaretha , Bipath Priyesh , Tosh Cheryl 
Published: March 2021

AbstractObjective:Pellagra is a nutritional deficiency disease associated with niacin (vitamin B3) deficiency. The history of pellagra is well documented for Europe and the USA, but less is known about the prevalence in sub-Saharan African countries. This study documents the history of pellagra in South Africa, as diagnosed based on dermatological symptoms.Design:Scoping review of information from scientific databases, library archives, other archives and record services and from Statistics South Africa.Setting:South Africa, 1897–2019.Participants:South African.Results:Pellagra was first officially recorded in South Africa in 1906, but there are earlier indications of the disease. The prevalence of pellagra peaked after it was all but eradicated in the USA and Europe. Pellagra was never as prevalent in South Africa as in Europe, the USA and Egypt, where special hospitals for pellagrins were established. However, studies on urinary excretion of metabolites conducted in 1960s and 1970s suggested a high prevalence of subclinical (sub-pellagra) niacin deficiency, especially in previously disadvantaged Black populations. As in Europe and the USA, pellagra was associated with poverty and an overdependence on maize as staple food. Malnutrition was the main cause of the disease, but alcohol abuse might have been a contributing factor. In South Africa, reports of pellagra had declined by the late 1980s/early 1990s and hardly any cases were reported by the year 2000.Conclusions:Although pellagra, diagnosed based on dermatological symptoms, appears to be largely eradicated in South Africa, it does not rule out the potential for subclinical niacin deficiency.
Prevalence of depressive symptoms among Chinese university students amid the COVID-19 pandemic: a systematic review and meta-analysis

Abstract

Aims
Chinese university students are at high risk for depressive symptoms and the ongoing coronavirus disease 2019 (COVID-19) pandemic may have exacerbated the mental health of university students. However, existing studies on depressive symptoms in Chinese university students during the COVID-19 pandemic reported a wide range of prevalence estimates, making mental health planning for this population difficult. The objective of this study was to conduct a systematic review and meta-analysis of surveys that assessed the prevalence of depressive symptoms in Chinese university students amid the COVID-19 pandemic.

Methods
Major Chinese (CNKI, Wanfang, VIP) and English (PubMed, Embase, PsycInfo) databases and preprint platforms were searched to identify cross-sectional studies containing data on the prevalence of depressive symptoms in Chinese university students during the pandemic. Two authors independently retrieved the literature, evaluated the eligibility of potential studies, assessed the risk of bias (RoB) of included studies, and extracted data. RoB was assessed with the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data.

Results
In total, 1177 records were retrieved, and 84 studies involving 1 292 811 Chinese university students during the pandemic were included. None of the included studies were rated as completely low RoB. Statistically significant heterogeneity in the prevalence estimates of included studies was detected (I2 = 99.9%, p < 0.001). The pooled prevalence of depressive symptoms was 26.0% (95%CI: 23.3–28.9%), which was significantly higher in female than in male students (30.8% v. 28.6%, p < 0.001), in postgraduates than in undergraduates (29.3% v. 22.9%, p < 0.001), in students living inside than in those living outside the COVID-19 epicentre (27.5% v. 22.3%, P < 0.001), in students from universities at the epicentre than in those from universities outside the epicentre (26.2% v. 23.1%, p < 0.001), in students who had close contact with COVID-19 than in those who did not (46.0% v. 25.0%, p < 0.001), and in students who had acquaintances or relatives infected with COVID-19 (39.7% v. 24.0%, p < 0.001) than in those who did not. Five sources of heterogeneity were identified from the subgroup analysis: survey period, % of males among the survey sample, scale of depressive symptoms, cutoff score of the scale and level of RoB.

Conclusions
Over one-fourth of Chinese university students experienced depressive symptoms during the COVID-19 pandemic. Mental health services for this population should include periodic evaluation of depressive symptoms, expanded social support and psychiatric assessment and treatment when necessary. It is also necessary to design depression prevention programmes that target higher-risk cohorts of university students.

Published: March 2021

AbstractThe critical zone (CZ) is the region of the Earth’s surface that extends from the bottom of the weathered bedrock to the tree canopy and is important because of its ability to store water and support ecosystems. A growing number of studies use active source shallow seismic refraction to explore and define the size and structure of the CZ across landscapes. However, measurement uncertainty and model resolution at depth are generally not evaluated, which makes the identification and interpretation of CZ features inconclusive. To reliably resolve seismic velocity with depth, we implement a Transdimensional Hierarchical Bayesian (THB) framework with reversible‐jump Markov Chain Monte Carlo to generate samples from the posterior distribution of velocity structures. We also perform 2D synthetic tests to explore how well THB traveltime inversion can resolve different subsurface velocity structures. We find that THB recovers both sharp changes in velocity as well as gradual velocity increases with depth. Furthermore, we explore the velocity structure in a series of ridge‐valley systems in northern California. The posterior velocity model shows an increasing thickness of low velocity material from channels to ridgetops along a transect parallel to bedding strike, implying a deeper weathering zone below ridgetops and hillslopes than below channels. The THB method enhances the ability to reliably image CZ structure, and the model uncertainty estimates it yields provides an objective way to interpret deep CZ structure. The method can be applied across other near‐surface studies, especially in the presence of significant surface topography.
The Atlantic Jet Response to Stratospheric Events: A Regime Perspective
Authors: Goss Michael , Lindgren Erik A. , Sheshadri Aditi , Diffenbaugh Noah S. 
Published: March 2021

AbstractThe tropospheric response to Sudden Stratospheric Warmings (SSWs) is associated with an equatorward shift in the midlatitude jet and associated storm tracks, while Strong Polar Vortex (SPV) events elicit a contrasting response. Recent analyses of the North Atlantic jet using probability density functions of a jet latitude index have identified three preferred jet latitudes, raising the question of whether the tropospheric response to SSWs and SPVs results from a change in relative frequencies of these preferred jet regimes rather than a systematic jet shift. We explore this question using atmospheric reanalysis data from 1979 to 2018 (26 SSWs and 33 SPVs), and a 202‐years integration of the Whole Atmosphere Community Climate Model (92 SSWs and 68 SPVs). Following SSWs, the northern jet regime becomes less common and the central and southern regimes become more common. These changes occur almost immediately following “split” vortex events, but are more delayed following “displacement” events. In contrast, the northern regime becomes more frequent and the southern regime less frequent following SPV events. Following SSWs, composites of 500‐hPa geopotential heights, surface air temperatures, and precipitation most closely resemble composites of the southern jet regime, and are generally opposite in sign to the composites of the northern jet regime. These comparisons are reversed following SPVs. Thus, one possible interpretation is that the two southernmost regimes appear to be favored following SSWs, while the southernmost regime becomes less common following SPVs.
