Characteristics of employment history and self-perceived barriers to healthcare access.

BACKGROUND: Research suggests that people in disadvantaged social positions are more likely to perceive barriers to accessing healthcare, especially to specialists and preventive services. In this study, we analyze if adversity during past employment histories (e.g. spells of unemployment) is linked to subsequent subjectively perceived barriers in healthcare access. Further, we investigate if the associations vary according to national healthcare access and quality indicators. METHODS: We use data from the Survey of Health, Ageing and Retirement in Europe with a study sample of 31 616 men and women aged 52-80 from 25 countries. Data include retrospective information on employment histories allowing us to derive characteristics of past careers, including the number of unemployment periods, main occupational position and pension contributions. Barriers to healthcare access are measured by self-perceived forgone care due to costs and unavailability of services. We apply multilevel Poisson regression for binary outcomes and test for cross-level interactions between career characteristics and national healthcare system characteristics. RESULTS: Career characteristics are linked to later self-perceived healthcare access barriers, consistently in the case of cost barriers and less consistently for unavailability of services. Associations are similar for men and women, and persist after controlling for current income, wealth and subjective health. We find no cross-level interactions between career characteristics and country-level healthcare access and quality indicators. CONCLUSION: Self-perceived barriers to healthcare access are linked to people's past working lives. More in-depth investigation is needed to identify the reasons for the lingering effects of characteristics of employment history on reduced healthcare access.

Far-right political ideology and COVID-19 vaccine hesitancy: Multilevel analysis of 21 European countries.

BACKGROUND: Far-right political parties across the EU have downplayed the risk of COVID-19 and have expressed skepticism toward the safety of the COVID-19 vaccine. This may affect the risk perception of people who support far-right parties and may be associated with an elevated risk of vaccine hesitancy. We aimed to explore if voting far-right is associated with COVID-19 vaccine hesitancy and if the association varies by individual and country-level factors. METHODS: We used cross-sectional data from 28,057 individuals nested in 21 countries who participated in the tenth round of the European Social Survey (ESS). COVID-19 vaccine hesitancy was assessed by asking respondents whether they will get vaccinated against COVID-19. Voting behavior was measured by asking respondents which party they voted for in the last election. To test the association between far-right voting and COVID-19 hesitancy, we applied a series of multilevel regression models. We additionally ran models including interaction terms to test if the association differs by sociodemographic characteristics (e.g., institutional trust) or contextual factors (e.g., income inequality). RESULTS: We found that far-right voters were 2.7 times more likely to be COVID-19 vaccine hesitant compared to center voters (PR: 2.69, 95% CI: 1.46-4.94). The association persisted even after controlling for institutional trust and social participation (adjusted PR: 2.15, 95% CI: 1.35-3.42). None of the tested interaction terms were significant suggesting that the association between political ideology and COVID-19 vaccine hesitancy does not differ by sociodemographic characteristics or contextual factors. CONCLUSION: Voting for far-right parties is associated with COVID-19 vaccine hesitancy. The association is similar among European countries, regardless of how stringent the public health measures were and magnitude of income inequality in each country. Our findings call for a more in-depth investigation of why, how and under which conditions political ideology affects vaccination behavior.

Mental Health, Loneliness, and Social Support Among Undergraduate Students: A Multinational Study in Asia.

In this study, we aimed to investigate the prevalence of poor mental health and its association with loneliness and social support among 3531 undergraduate students in nine Asian countries. Mental health was assessed using the Self-Reporting Questionnaire, which was developed by the World Health Organization. Across the entire sample, we detected that nearly half of the students reported poor mental health according to the Self-Reporting Questionnaire and nearly one out of seven students felt lonely. While feeling lonely increased the odds of experiencing poor mental health (odds ratio [OR]), moderate (OR: 0.35) and strong social support (OR: 0.18) decreases the odds of experiencing poor mental health. The high prevalence of poor mental health calls for further in-depth investigations and implementation of mental health support interventions.

Coping with the mental health impact of COVID-19: A study protocol for a multinational longitudinal study on coping and resilience during the COVID-19 pandemic.

BACKGROUND: Mental health is challenged due to serious life events such as the COVID-19 pandemic and can differ by the level of resilience. National studies on mental health and resilience of individuals and communities during the pandemic provide heterogeneous results and more data on mental health outcomes and resilience trajectories are needed to better understand the impact of the pandemic on mental health in Europe. METHODS: COPERS (Coping with COVID-19 with Resilience Study) is an observational multinational longitudinal study conducted in eight European countries (Albania, Belgium, Germany, Italy, Lithuania, Romania, Serbia, and Slovenia). Recruitment of participants is based on convenience sampling and data are gathered through an online questionnaire. gathering data on depression, anxiety, stress-related symptoms suicidal ideation and resilience. Resilience is measured with the Brief Resilience Scale and with the Connor-Davidson Resilience Scale. Depression is measured with the Patient Health Questionnaire, Anxiety with the Generalized Anxiety Disorder Scale and stress-related symptoms with the Impact of Event Scale Revised- Suicidal ideation is assessed using item 9 of the PHQ-9. We also consider potential determinants and moderating factors for mental health conditions, including sociodemographic characteristics (e.g., age, gender), social environmental factors (e.g., loneliness, social capital) and coping strategies (e.g., Self-efficacy Belief). DISCUSSION: To the best of our knowledge, this is the first study to multi-nationally and longitudinally determine mental health outcomes and resilience trajectories in Europe during the COVID-19 pandemic. The results of this study will help to determine mental health conditions during the COVID-19 pandemic across Europe. The findings may benefit pandemic preparedness planning and future evidence-based mental health policies.

Changes in work-related stressors before and during the COVID-19 pandemic: differences by gender and parental status.

PURPOSE: The COVID-19 pandemic changed people's working conditions worldwide and research suggests increases in work stressors. However, it is not known to what extent these changes differ by gender or parental status. In the present study, we investigate trends in work stressors and whether these differ by gender and parental status. METHODS: We used cross-sectional time series data of the European Working Conditions Survey of 2015 and Living, Working and COVID-19 survey of spring 2020 to examine trends in work stressors by gender and parental status. Work stressors were working in leisure time, lack of psychological detachment and work-life conflict. We applied three-way multilevel regressions reporting prevalence ratios and reported predicted probabilities and average marginal effects to show trends and differences in changes in work stressors. RESULTS: Our multilevel regression results showed elevated prevalence ratios during the pandemic for working leisure time (PR: 1.43, 95% CI 1.34-1.53), psychological detachment (PR: 1.70, 95% CI 1.45-1.99) and work-life conflict (PR: 1.29, 95% CI 1.17-1.43) compared to before the pandemic. Except for working in leisure time, the increase was more significant among women and mothers. The proportion of work-life conflict in 2020 was 20.7% (95% CI 18.7-22.9) for men and 25.8% (95% CI 24.0-27.6) for women, equalling a difference of 5.1% (p < 0.001). CONCLUSIONS: There is evidence that work stressors increased disproportionately for women and mothers. This needs to be monitored and addressed to prevent widening gender inequalities in the quality of work.

Social Capital and Lifestyle Impacts on Mental Health in University Students in Colombia: An Observational Study.

Introduction: For young adults, the first year of higher education represents a transition period into adulthood associated with an increased risk of developing depression, anxiety, and stress, contributing to deteriorating physical and mental health. The present study aimed to analyze the relationship between depressive symptoms and social capital and lifestyles among Colombian university students. Methods: In 2020, a longitudinal repeated measures study was conducted on first year students at Universidad de los Andes in Bogota, Colombia. The study was conceptualized and approved by the university before the COVID-19 pandemic appeared. Each student completed a self-administered questionnaire including questions on sociodemographic characteristics, depressive symptoms, perceived stress, social capital, and lifestyles. The study's pilot was conducted in November 2019, and the two measurement points were in January 2020 (wave 1, before the COVID-19 pandemic was declared) and in August 2020 (wave 2, during the COVID-19 pandemic). A binary logistic regression analysis was performed to assess the relationship between depressive symptoms, perceived stress, social capital, and lifestyles. Findings: A total of 609 first year students (response rate = 58.11%) participated in wave 1, and 42% of the participants showed signs of clinically relevant depressive symptoms. In wave 2, despite the difficulties encountered in collecting data due to the COVID-19 pandemic, 216 students from wave 1 participated (35.47%). An increase in a sedentary lifestyle was observed (31.49%). We found that cognitive and behavioral social capital levels decreased by 12.03 and 24.54%, respectively. In addition, we observed a 6.5% increase in students with clinically relevant depressive symptoms compared to wave 1. A low level of behavioral [OR: 1.88; 95% CI (1.16, 3.04)] social capital was associated with clinically relevant depressive symptoms. Conclusion: The health of university students continues to be a public health concern. The study suggests that social capital may play an important role in preventing depressive symptoms. Therefore, universities should put effort into programs that bring students together and promote the creation of social capital.

Striving for Health Equity: The Importance of Social Determinants of Health and Ethical Considerations in Pandemic Preparedness Planning.

Since the WHO's "Influenza Pandemic Preparedness Plan" in 1999, pandemic preparedness plans at the international and national level have been constantly adapted with the common goal to respond early to outbreaks, identify risks, and outline promising interventions for pandemic containment. Two years into the COVID-19 pandemic, public health experts have started to reflect on the extent to which previous preparations have been helpful as well as on the gaps in pandemic preparedness planning. In the present commentary, we advocate for the inclusion of social and ethical factors in future pandemic planning-factors that have been insufficiently considered so far, although social determinants of infection risk and infectious disease severity contribute to aggravated social inequalities in health.

Effectiveness of digital mental health interventions for university students: an umbrella review.

Background: Poor mental health among university students remains a pressing public health issue. Over the past few years, digital health interventions have been developed and considered promising in increasing psychological wellbeing among university students. Therefore, this umbrella review aims to synthesize evidence on digital health interventions targeting university students and to evaluate their effectiveness. Methods: A systematic literature search was performed in April 2021 searching PubMed, Psychology and Behavioural Science Collection, Web of Science, ERIC, and Scopus for systematic reviews and meta-analyses on digital mental health interventions targeting university students. The review protocol was registered in the International Prospective Register of Systematic Reviews PROSPERO [CRD42021234773]. Results: The initital literature search resulted in 806 records of which seven remained after duplicates were removed and evaluated against the inclusion criteria. Effectiveness was reported and categorized into the following six delivery types: (a) web-based, online/computer-delivered interventions (b) computer-based Cognitive Behavior Therapy (CBT), (c) mobile applications and short message service (d) virtual reality interventions (e) skills training (f) relaxation and exposure-based therapy. Results indicated web-based online/computer delivered-interventions were effective or at least partially effective at decressing depression, anxiety, stress and eating disorder symptoms. This was similar for skills-training interventions, CBT-based intervention and mobile applications. However, digital mental health interventions using virtual reality and relaxation, exposure-based therapy was inconclusive. Due to the variation in study settings and inconsistencies in reporting, effectiveness was greatly dependent on the delivery format, targeted mental health problem and targeted purpose group. Conclusion: The findings provide evidence for the beneficial effect of digital mental health interventions for university students. However, this review calls for a more systematic approach in testing and reporting the effectiveness of digital mental health interventions.

Economic change and population health: lessons learnt from an umbrella review on the Great Recession.

OBJECTIVES: Worldwide, the COVID-19 pandemic triggered the sharpest economic downturn since the Great Recession. To prepare for future crises and to preserve public health, we conduct an overview of systematic reviews to examine the evidence on the effect of the Great Recession on population health. METHODS: We searched PubMed and Scopus for systematic reviews and/or meta-analyses focusing specifically on the impact of the Great Recession on population health (eg, mental health). Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines were followed throughout this review and critical appraisal of included systematic reviews was performed using Assessing the Methodological Quality of Systematic Reviews. RESULTS: Twenty-one studies were identified and consistently showed that the Great Recession was most risky to health, the more a country's economy was affected and the longer strict austerity policies were in place. Consequently, a deterioration of health was highest in countries that had implemented strict austerity measures (eg, Greece), but not in countries that rejected austerity measures (eg, Germany). Moreover, the impact of the Great Recession fell disproportionately on the most vulnerable groups such as people in unemployment, at risk of unemployment and those living in poverty. CONCLUSIONS: The experiences of the last economic crisis show that it is possible to limit the consequences for health. Prioritising mental healthcare and prevention, foregoing austerity measures in the healthcare system and protecting vulnerable groups are the most important lessons learnt. Moreover, given the further aggravating social inequalities, a health in all policies approach, based on a comprehensive Health Impact Assessment, is advised.

Association between social capital indicators and depressive symptoms among Brazilian university students.

The study aimed to investigate the association between social capital indicators and depressive symptoms among university students from Brazil. The study drew on a sample of 579 randomly selected university students, from a greater crossnational study conducted in 2018. Students completed a self-administered questionnaire assessing depressive symptoms, indicators of social capital and lifestyle behaviors. Data were analyzed using multivariate logistic regression models. Indicators of social capital included trust, group membership and frequency of meeting friends. Four social capital indicators were significantly associated with clinically relevant depressive symptoms. Students who agreed that people are likely to take advantage of one another were more likely to report depressive clinically relevant symptoms (OR: 1.80, 95%CI: 1.00 - 3.23) as well as students who agreed that people are not willing to help in case needed (OR: 2.11, 95%CI: 1.02 - 4.36). Perceived stress, smoking and hazardous alcohol consumption were not associated with clinically relevant depressive symptoms. Social capital plays an important role in explaining depressive symptoms among Brazilian university students. The study suggests that creating trust and enhancing participation in social networks can be an important strategy for promoting mental health among university students investigated in this study.

Resumo O estudo investigou a associação entre indicadores de capital social e sintomas depressivos entre estudantes universitários do Brasil. Um estudo transversal foi conduzido com uma amostra de 579 estudantes universitários selecionados randomicamente em 2018. Os estudantes completaram questionários auto-administrados para avaliar sintomas depressivos, indicadores de capital social e comportamentos de estilos de vida. Os dados foram analisados usando modelos de regressão logística multivariada. Indicadores de capital social incluíam confiança, associações em grupos, frequência de encontrar com os amigos, entre outros. Quatro indicadores de capital social se associaram significativamente com relevantes sintomas clínicos de depressão. Estudantes que disseram que as pessoas tendem a tirar mais vantagens umas das outras eram mais propensas a relatar sintomas clínicos relevantes de depressão (OR: 1.80, 95%CI: 1.00 - 3.23), assim como estudantes que relataram que as pessoas não estão dispostas a ajudar caso precise de ajuda (OR: 2.11, 95%CI: 1.02 - 4.36). A autopercepção de estresse, o consumo de álcool e o fumo não se associaram aos sintomas clínicos de depressão. O capital social desempenha um papel importante na explicação dos sintomas depressivos entre os universitários brasileiros. O estudo sugere que promover confiança e aumentar a participação nas redes sociais pode ser uma estratégia importante para a promoção da saúde mental entre os universitários investigados neste estudo.

Long-Term Course of Humoral and Cellular Immune Responses in Outpatients After SARS-CoV-2 Infection.

Characterization of the naturally acquired B and T cell immune responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is important for the development of public health and vaccination strategies to manage the burden of COVID-19 disease. We conducted a prospective, cross-sectional analysis in COVID-19 recovered patients at various time points over a 10-month period in order to investigate how circulating antibody levels and interferon-gamma (IFN-γ) release by peripheral blood cells change over time following natural infection. From March 2020 till January 2021, we enrolled 412 adults mostly with mild or moderate disease course. At each study visit, subjects donated peripheral blood for testing of anti-SARS-CoV-2 IgG antibodies and IFN-γ release after SARS-CoV-2 S-protein stimulation. Anti-SARS-CoV-2 immunoglobulin G (IgG) antibodies were positive in 316 of 412 (76.7%) and borderline in 31 of 412 (7.5%) patients. Our confirmation assay for the presence of neutralizing antibodies was positive in 215 of 412 (52.2%) and borderline in 88 of 412 (21.4%) patients. Likewise, in 274 of 412 (66.5%) positive IFN-γ release and IgG antibodies were detected. With respect to time after infection, both IgG antibody levels and IFN-γ concentrations decreased by about half within 300 days. Statistically, production of IgG and IFN-γ were closely associated, but on an individual basis, we observed patients with high-antibody titres but low IFN-γ levels and vice versa. Our data suggest that immunological reaction is acquired in most individuals after natural infection with SARS-CoV-2 and is sustained in the majority of patients for at least 10 months after infection after a mild or moderate disease course. Since, so far, no robust marker for protection against COVID-19 exists, we recommend utilizing both, IgG and IFN-γ release for an individual assessment of the immunity status.

Sexual assault, sense of belonging, depression and suicidality among LGBQ and heterosexual college students.

OBJECTIVE: To compare the effect of sexual orientation, history of sexual assault and sense of belonging on depression and suicidality among lesbian, gay, bisexual, queer and questioning (LGBQ) and heterosexual students. Participants: A total of 60,194 students from 60 US campuses who participated in the 2017-2018 Healthy Minds Study. Methods: Three-way interaction effects were analyzed using PROCESS macro models in SPSS. Results: Significant three-way interaction effects were found for sexual orientation, sexual assault and sense of belonging predicting depressive symptoms (b = -0.06, p= 0.042, CI: -0.12 to -0.00), and suicidality (b = -0.10, p= 0.004, CI: -0.01 to -0.003). The effect of sexual assault on mental health differed depending on sexual orientation and sense of belonging. Particularly among LGBQ students, high sense of belonging was protective in the presence of sexual assault, and its absence had a deleterious effect on mental health. Conclusion: Enhancing sense of belonging may represent a strategy to mitigate depression and promote suicide prevention, particularly among LGBQ students.

Antibody Profiling of COVID-19 Patients in an Urban Low-Incidence Region in Northern Germany.

A vast majority of COVID-19 cases present with mild or moderate symptoms. The study region is in an urban and well-defined environment in a low-incidence region in Northern Germany. In the present study, we explored the dynamics of the antibody response with respect to onset, level and duration in patients with confirmed SARS-CoV-2 infection. Anti-SARS-CoV-2 IgG and IgA were detected by automated enzyme-linked immunosorbent assay (ELISA) of SARS-CoV-2 infected patients monitored by the Health Protection Authority. This explorative monocentric study shows IgA and IgG antibody profiles from 118 patients with self-reported mild to moderate, or no COVID-19 related symptoms after laboratory-confirmed infection with SARS-CoV-2. We found that 21.7% and 18.1% of patients were seronegative for IgA or IgG, respectively. Clinically, most of the seronegative patients showed no to only moderate symptoms. With regard to antibody profiling 82% of all patients developed sustainable antibodies (IgG) and 78% (IgA) 3 weeks or later after the infection. Our data indicate that antibody-positivity is a useful indicator of a previous SARS-CoV-2 infection. Negative antibodies do not rule out SARS-CoV-2 infection. Future studies are needed to determine the functionality of the antibodies in terms of neutralization capacity leading to personal protection and prevention ability to transmit the virus as well as to protect after vaccination.

Drugs for preventing postoperative nausea and vomiting in adults after general anaesthesia: a network meta-analysis.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a common adverse effect of anaesthesia and surgery. Up to 80% of patients may be affected. These outcomes are a major cause of patient dissatisfaction and may lead to prolonged hospital stay and higher costs of care along with more severe complications. Many antiemetic drugs are available for prophylaxis. They have various mechanisms of action and side effects, but there is still uncertainty about which drugs are most effective with the fewest side effects. OBJECTIVES: • To compare the efficacy and safety of different prophylactic pharmacologic interventions (antiemetic drugs) against no treatment, against placebo, or against each other (as monotherapy or combination prophylaxis) for prevention of postoperative nausea and vomiting in adults undergoing any type of surgery under general anaesthesia • To generate a clinically useful ranking of antiemetic drugs (monotherapy and combination prophylaxis) based on efficacy and safety • To identify the best dose or dose range of antiemetic drugs in terms of efficacy and safety SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), ClinicalTrials.gov, and reference lists of relevant systematic reviews. The first search was performed in November 2017 and was updated in April 2020. In the update of the search, 39 eligible studies were found that were not included in the analysis (listed as awaiting classification). SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing effectiveness or side effects of single antiemetic drugs in any dose or combination against each other or against an inactive control in adults undergoing any type of surgery under general anaesthesia. All antiemetic drugs belonged to one of the following substance classes: 5-HT3 receptor antagonists, D2 receptor antagonists, NK1 receptor antagonists, corticosteroids, antihistamines, and anticholinergics. No language restrictions were applied. Abstract publications were excluded. DATA COLLECTION AND ANALYSIS: A review team of 11 authors independently assessed trials for inclusion and risk of bias and subsequently extracted data. We performed pair-wise meta-analyses for drugs of direct interest (amisulpride, aprepitant, casopitant, dexamethasone, dimenhydrinate, dolasetron, droperidol, fosaprepitant, granisetron, haloperidol, meclizine, methylprednisolone, metoclopramide, ondansetron, palonosetron, perphenazine, promethazine, ramosetron, rolapitant, scopolamine, and tropisetron) compared to placebo (inactive control). We performed network meta-analyses (NMAs) to estimate the relative effects and ranking (with placebo as reference) of all available single drugs and combinations. Primary outcomes were vomiting within 24 hours postoperatively, serious adverse events (SAEs), and any adverse event (AE). Secondary outcomes were drug class-specific side effects (e.g. headache), mortality, early and late vomiting, nausea, and complete response. We performed subgroup network meta-analysis with dose of drugs as a moderator variable using dose ranges based on previous consensus recommendations. We assessed certainty of evidence of NMA treatment effects for all primary outcomes and drug class-specific side effects according to GRADE (CINeMA, Confidence in Network Meta-Analysis). We restricted GRADE assessment to single drugs of direct interest compared to placebo. MAIN RESULTS: We included 585 studies (97,516 randomized participants). Most of these studies were small (median sample size of 100); they were published between 1965 and 2017 and were primarily conducted in Asia (51%), Europe (25%), and North America (16%). Mean age of the overall population was 42 years. Most participants were women (83%), had American Society of Anesthesiologists (ASA) physical status I and II (70%), received perioperative opioids (88%), and underwent gynaecologic (32%) or gastrointestinal surgery (19%) under general anaesthesia using volatile anaesthetics (88%). In this review, 44 single drugs and 51 drug combinations were compared. Most studies investigated only single drugs (72%) and included an inactive control arm (66%). The three most investigated single drugs in this review were ondansetron (246 studies), dexamethasone (120 studies), and droperidol (97 studies). Almost all studies (89%) reported at least one efficacy outcome relevant for this review. However, only 56% reported at least one relevant safety outcome. Altogether, 157 studies (27%) were assessed as having overall low risk of bias, 101 studies (17%) overall high risk of bias, and 327 studies (56%) overall unclear risk of bias. Vomiting within 24 hours postoperatively Relative effects from NMA for vomiting within 24 hours (282 RCTs, 50,812 participants, 28 single drugs, and 36 drug combinations) suggest that 29 out of 36 drug combinations and 10 out of 28 single drugs showed a clinically important benefit (defined as the upper end of the 95% confidence interval (CI) below a risk ratio (RR) of 0.8) compared to placebo. Combinations of drugs were generally more effective than single drugs in preventing vomiting. However, single NK1 receptor antagonists showed treatment effects similar to most of the drug combinations. High-certainty evidence suggests that the following single drugs reduce vomiting (ordered by decreasing efficacy): aprepitant (RR 0.26, 95% CI 0.18 to 0.38, high certainty, rank 3/28 of single drugs); ramosetron (RR 0.44, 95% CI 0.32 to 0.59, high certainty, rank 5/28); granisetron (RR 0.45, 95% CI 0.38 to 0.54, high certainty, rank 6/28); dexamethasone (RR 0.51, 95% CI 0.44 to 0.57, high certainty, rank 8/28); and ondansetron (RR 0.55, 95% CI 0.51 to 0.60, high certainty, rank 13/28). Moderate-certainty evidence suggests that the following single drugs probably reduce vomiting: fosaprepitant (RR 0.06, 95% CI 0.02 to 0.21, moderate certainty, rank 1/28) and droperidol (RR 0.61, 95% CI 0.54 to 0.69, moderate certainty, rank 20/28). Recommended and high doses of granisetron, dexamethasone, ondansetron, and droperidol showed clinically important benefit, but low doses showed no clinically important benefit. Aprepitant was used mainly at high doses, ramosetron at recommended doses, and fosaprepitant at doses of 150 mg (with no dose recommendation available). Frequency of SAEs Twenty-eight RCTs were included in the NMA for SAEs (10,766 participants, 13 single drugs, and eight drug combinations). The certainty of evidence for SAEs when using one of the best and most reliable anti-vomiting drugs (aprepitant, ramosetron, granisetron, dexamethasone, ondansetron, and droperidol compared to placebo) ranged from very low to low. Droperidol (RR 0.88, 95% CI 0.08 to 9.71, low certainty, rank 6/13) may reduce SAEs. We are uncertain about the effects of aprepitant (RR 1.39, 95% CI 0.26 to 7.36, very low certainty, rank 11/13), ramosetron (RR 0.89, 95% CI 0.05 to 15.74, very low certainty, rank 7/13), granisetron (RR 1.21, 95% CI 0.11 to 13.15, very low certainty, rank 10/13), dexamethasone (RR 1.16, 95% CI 0.28 to 4.85, very low certainty, rank 9/13), and ondansetron (RR 1.62, 95% CI 0.32 to 8.10, very low certainty, rank 12/13). No studies reporting SAEs were available for fosaprepitant. Frequency of any AE Sixty-one RCTs were included in the NMA for any AE (19,423 participants, 15 single drugs, and 11 drug combinations). The certainty of evidence for any AE when using one of the best and most reliable anti-vomiting drugs (aprepitant, ramosetron, granisetron, dexamethasone, ondansetron, and droperidol compared to placebo) ranged from very low to moderate. Granisetron (RR 0.92, 95% CI 0.80 to 1.05, moderate certainty, rank 7/15) probably has no or little effect on any AE. Dexamethasone (RR 0.77, 95% CI 0.55 to 1.08, low certainty, rank 2/15) and droperidol (RR 0.89, 95% CI 0.81 to 0.98, low certainty, rank 6/15) may reduce any AE. Ondansetron (RR 0.95, 95% CI 0.88 to 1.01, low certainty, rank 9/15) may have little or no effect on any AE. We are uncertain about the effects of aprepitant (RR 0.87, 95% CI 0.78 to 0.97, very low certainty, rank 3/15) and ramosetron (RR 1.00, 95% CI 0.65 to 1.54, very low certainty, rank 11/15) on any AE. No studies reporting any AE were available for fosaprepitant. Class-specific side effects For class-specific side effects (headache, constipation, wound infection, extrapyramidal symptoms, sedation, arrhythmia, and QT prolongation) of relevant substances, the certainty of evidence for the best and most reliable anti-vomiting drugs mostly ranged from very low to low. Exceptions were that ondansetron probably increases headache (RR 1.16, 95% CI 1.06 to 1.28, moderate certainty, rank 18/23) and probably reduces sedation (RR 0.87, 95% CI 0.79 to 0.96, moderate certainty, rank 5/24) compared to placebo. The latter effect is limited to recommended and high doses of ondansetron. Droperidol probably reduces headache (RR 0.76, 95% CI 0.67 to 0.86, moderate certainty, rank 5/23) compared to placebo. We have high-certainty evidence that dexamethasone (RR 1.00, 95% CI 0.91 to 1.09, high certainty, rank 16/24) has no effect on sedation compared to placebo. No studies assessed substance class-specific side effects for fosaprepitant. Direction and magnitude of network effect estimates together with level of evidence certainty are graphically summarized for all pre-defined GRADE-relevant outcomes and all drugs of direct interest compared to placebo in http://doi.org/10.5281/zenodo.4066353. AUTHORS' CONCLUSIONS: We found high-certainty evidence that five single drugs (aprepitant, ramosetron, granisetron, dexamethasone, and ondansetron) reduce vomiting, and moderate-certainty evidence that two other single drugs (fosaprepitant and droperidol) probably reducevomiting, compared to placebo. Four of the six substance classes (5-HT3 receptor antagonists, D2 receptor antagonists, NK1 receptor antagonists, and corticosteroids) were thus represented by at least one drug with important benefit for prevention of vomiting. Combinations of drugs were generally more effective than the corresponding single drugs in preventing vomiting. NK1 receptor antagonists were the most effective drug class and had comparable efficacy to most of the drug combinations. 5-HT3 receptor antagonists were the best studied substance class. For most of the single drugs of direct interest, we found only very low to low certainty evidence for safety outcomes such as occurrence of SAEs, any AE, and substance class-specific side effects. Recommended and high doses of granisetron, dexamethasone, ondansetron, and droperidol were more effective than low doses for prevention of vomiting. Dose dependency of side effects was rarely found due to the limited number of studies, except for the less sedating effect of recommended and high doses of ondansetron. The results of the review are transferable mainly to patients at higher risk of nausea and vomiting (i.e. healthy women undergoing inhalational anaesthesia and receiving perioperative opioids). Overall study quality was limited, but certainty assessments of effect estimates consider this limitation. No further efficacy studies are needed as there is evidence of moderate to high certainty for seven single drugs with relevant benefit for prevention of vomiting. However, additional studies are needed to investigate potential side effects of these drugs and to examine higher-risk patient populations (e.g. individuals with diabetes and heart disease).

ImmunizziAMO: A School-Based Field Trial to Teach New Generations the Importance of Vaccination through Games and to Fight Vaccine Hesitancy in Italy.

BACKGROUND: Vaccines simulate the first contact with infectious agents and evoke the immunological response without causing the disease and its complications. High rates of immunization among the population guarantee the interruption of the transmission chain of infectious diseases. Therefore, the population should be aware of the value of vaccination and motivated. In order to implement the spread of a correct culture about these issues, schools were recognized as a privileged operational setting. The aim of this project was to transmit knowledge and convey educational messages on the importance of vaccines, through the use of games, in elementary school children, their families and teachers. MATERIALS AND METHODS: A field trial study was implemented between April and October 2019. Sample size calculations highlighted the need to recruit at least 136 students in the schools. The intervention involved 10 classes (five first grade and five s grade classes) and was structured in frontal teaching sessions and gaming sessions. Knowledge was assessed comparing the results of a questionnaire administered before and after the intervention. The questionnaires referred to the following items: dangerousness of bacteria and viruses; capability of defending from microorganisms; the role of antibodies; functioning of the vaccine in a child; type of disease for which a vaccine is efficacious; duration of a vaccine; mother- child transmission of antibodies; herd immunity. RESULTS: 143 children participated in all the phases of the study. The comparison between the scores at the beginning and end of the intervention showed a significant increase in the knowledge about vaccines and immunity. The mean knowledge score arose from 3.52 (SD = 1.67) to 5.97 (SD = 1.81). CONCLUSIONS: This study suggests that the use of games in an elementary school effectively increase the knowledge related to the important topic of vaccination starting at childhood.

Associations Between Social Capital and Depressive Symptoms Among College Students in 12 Countries: Results of a Cross-National Study.

INTRODUCTION: A mental health crisis has hit university campuses across the world. This study sought to determine the prevalence and social determinants of depressive symptoms among university students in twelve countries. Particular focus was placed on the association between social capital and depressive symptoms. METHODS: A cross-sectional study was conducted among students at their first year at university in Europe, Asia, the Western Pacific, and Latin and North America. Data were obtained through a self-administered questionnaire, including questions on sociodemographic characteristics, depressive symptoms, and social capital. The simplified Beck's Depression Inventory was used to measure the severity of depressive symptoms. Social capital was assessed using items drawn from the World Bank Integrated Questionnaire to Measure Social Capital. Multilevel analyses were conducted to determine the relationship between social capital and depressive symptoms, adjusting for individual covariates (e.g., perceived stress) and country-level characteristics (e.g., economic development). RESULTS: Among 4228 students, 48% presented clinically relevant depressive symptoms. Lower levels of cognitive (OR: 1.82, 95% CI: 1.44-2.29) and behavioral social capital (OR: 1.51, 95% CI: 1.29-1.76) were significantly associated with depressive symptoms. The likelihood of having depressive symptoms was also significantly higher among those living in regions with lower levels of social capital. CONCLUSION: The study demonstrates that lower levels of individual and macro-level social capital contribute to clinically relevant depressive symptoms among university students. Increasing social capital may mitigate depressive symptoms in college students.

Are There Effective Interventions to Increase Physical Activity in Children and Young People? An Umbrella Review.

BACKGROUND: Obesity and physical inactivity among children and young people are public health concerns. While numerous interventions to promote physical activity are available, little is known about the most effective ones. This study aimed to summarize the existing evidence on interventions that aim to increase physical activity. METHODS: A systematic review of reviews was conducted. Systematic reviews and meta-analyses published from January 2010 until November 2017 were identified through PubMed, Scopus and the Cochrane Library. Two reviewers independently assessed titles and abstracts, performed data extraction and quality assessment. Outcomes as level of physical activity and body mass index were collected in order to assess the efficacy of interventions. RESULTS: A total 30 studies examining physical activity interventions met the inclusion criteria, 15 systematic reviews and 15 meta-analyses. Most studies (N = 20) were implemented in the school setting, three were developed in preschool and childcare settings, two in the family context, five in the community setting and one miscellaneous context. Results showed that eight meta-analyses obtained a small increase in physical activity level, out of which five were conducted in the school, two in the family and one in the community setting. Most promising programs had the following characteristics: included physical activity in the school curriculum, were long-term interventions, involved teachers and had the support of families. CONCLUSION: The majority of interventions to promote physical activity in children and young people were implemented in the school setting and were multicomponent. Further research is needed to investigate nonschool programs.
