Effect of high-dose Spirulina supplementation on hospitalized adults with COVID-19: a randomized controlled trial.

Objective: Spirulina (arthrospira platensis) is a cyanobacterium proven to have anti-inflammatory, antiviral, and antioxidant effects. However, the effect of high-dose Spirulina supplementation on hospitalized adults with COVID-19 is currently unclear. This study aimed to evaluate the efficacy and safety of high-dose Spirulina platensis for SARS-CoV-2 infection. Study Design: We conducted a randomized, controlled, open-label trial involving 189 patients with COVID-19 who were randomly assigned in a 1:1 ratio to an experimental group that received 15.2g of Spirulina supplement plus standard treatment (44 non-intensive care unit (non-ICU) and 47 ICU), or to a control group that received standard treatment alone (46 non-ICU and 52 ICU). The study was conducted over six days. Immune mediators were monitored on days 1, 3, 5, and 7. The primary outcome of this study was mortality or hospital discharge within seven days, while the overall discharge or mortality was considered the secondary outcome. Results: Within seven days, there were no deaths in the Spirulina group, while 15 deaths (15.3%) occurred in the control group. Moreover, within seven days, there was a greater number of patients discharged in the Spirulina group (97.7%) in non-ICU compared to the control group (39.1%) (HR, 6.52; 95% CI, 3.50 to 12.17). Overall mortality was higher in the control group (8.7% non-ICU, 28.8% ICU) compared to the Spirulina group (non-ICU HR, 0.13; 95% CI, 0.02 to 0.97; ICU, HR, 0.16; 95% CI, 0.05 to 0.48). In non-ICU, patients who received Spirulina showed a significant reduction in the levels of IL-6, TNF-α, IL-10, and IP-10 as intervention time increased. Furthermore, in ICU, patients who received Spirulina showed a significant decrease in the levels of MIP-1α and IL-6. IFN-γ levels were significantly higher in the intervention group in both ICU and non-ICU subgroups as intervention time increased. No side effects related to Spirulina supplements were observed during the trial. Conclusion: High-dose Spirulina supplements coupled with the standard treatment of COVID-19 may improve recovery and remarkably reduce mortality in hospitalized patients with COVID-19.

Self-protective behaviors of Thai village health volunteers in community engagement during a COVID-19 outbreak: interpretation using the health belief model.

BACKGROUND: Village health volunteers (VHVs) engaging in community-based COVID-19 prevention and control measures played a key role in mitigating effects of the COVID-19 pandemic in Thailand. We conducted a cross-sectional questionnaire survey study to investigate factors affecting VHVs' COVID-19 self-protective behaviors and social distancing in Songkhla Province during the first COVID-19 outbreak. Such information may help to understand how to support VHVs in future pandemics. METHODS: A total of 152 VHVs from 13 sub-districts participated in the study, completing a 54-item questionnaire based on the Health Belief Model (HBM). The questionnaire included items assessing susceptibility, severity, benefits, barriers, self-efficacy, social distancing, and self-protective behavior. Stepwise multiple regression analysis determined which aspects of the HBM could explain VHVs' self-protective behavior. RESULTS: The VHV population sampled broadly reflected the main demographic characteristics of the local population, although VHVs were predominantly female. Self-protective behavior was significantly associated with VHVs' role (higher perceived compliance for village leaders than non-leaders) but not with other demographic characteristics. Most VHVs reported high levels of self-efficacy (80.5%), adherence to social distancing measures (70.9%), and engagement in self-protective behavior (72.8%) against COVID-19. However, compliance with hand hygiene appeared to be suboptimal, suggesting room for improvement. Self-efficacy and perceived social distancing showed strong and moderate correlations with self-protective behavior against COVID-19 (r = 0.917, ß = 0.819; and r = 0.561, ß = 0.173 respectively; p < 0.001). The final HBM-based regression model accounted for 87.2% of the variance in VHVs' self-protective behavior. CONCLUSIONS: This study highlights the importance of VHVs' self-efficacy for achieving self-protective behavior during a COVID-19 outbreak, and suggests that self-efficacy may help to overcome barriers that might otherwise hinder behaviors to mitigate against COVID-19. Policies that support self-efficacy should be implemented in any future pandemic, and steps to support VHVs with hand hygiene compliance and empower non-leaders to increase their self-protective behavior may also be helpful. Whilst the HBM provided a useful framework for interpretation, the final model was driven mainly by self-efficacy.

Comparison of Omicron and Delta Variants of SARS-CoV-2: A Systematic Review of Current Evidence.

INTRODUCTION: Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) caused the outbreak of coronavirus disease 2019 (COVID-19) in late 2019 in Wuhan, China. In early 2020, the disease spread rapidly around the world. Since the pandemic, SARS-CoV-2 has evolved dramatically into a wide variety of variants endowed with devastating properties. As of March 6, 2022, five SARS-CoV-2 variants of concern, including Alpha, Beta, Gamma, Delta, and Omicron strains have been identified. Due to the crucial importance of understanding the differences between the Omicron and Delta variants, this systematic review was conducted. METHODS: This systematic review investigated new variants of Omicron SARS-CoV-2 based on cur-rent studies. Online databases were searched for English articles as of January 03, 2023. Selection of publications was a two-step process of title/abstract and full-text assessment against eligibility crite-ria. The relevant data from the included articles were systematically collected and organized in a designed table for analysis. To ensure the quality of the review, the PRISMA checklist and Newcas-tle-Ottawa Scale (NOS) of quality assessment were utilized. RESULTS: The data extracted from 58 articles were analyzed, including 10003 pieces of evidence. Lower risk of hospitalization, ICU admission, and mortality after vaccination were reported in the Omicron variant compared to the Delta variant. Additionally, the Delta variant led to more severe clinical symptoms in comparison to the Omicron variant. CONCLUSION: The Omicron variant of SARS-CoV-2 results in less severe disease outcomes as com-pared to Delta. Nevertheless, it remains crucial to maintain ongoing monitoring, implement contain-ment measures, and adapt vaccination protocols to effectively address the evolving variants.

Traditional, cyberbullying, and suicidal behaviors in Argentinian adolescents: the protective role of school, parental, and peer connectedness.

Introduction: Bullying, both in person and online, is a significant risk factor for a range of negative outcomes including suicidal behaviors among adolescents and it is crucial to explore the protective effects of parental, school, and peer connectedness on suicidal behaviors among victims. Methods: This study is a secondary analysis of the Argentina Global School-based Student Health Survey (GSHS 2018). Logistic regression analysis, adjusting for age and sex, determines the likelihood of suicidal thoughts and attempts among bullying victims. To explore the modifying effect of school, parental, and peer connectedness on the association between bullying and suicide behaviors, the interaction term was included. Sampling design and weights were applied in all analyses in STATA 17. Results: The study included 56,783 students in grades 8-12, with over half being female. Adolescents aged 14-15 exhibited the highest prevalence of bullying, cyberbullying, suicidal thoughts, and attempts, with females displaying a higher prevalence in all measured categories. The study found that adolescents who reported being bullied or cyberbullied demonstrated a significantly higher likelihood of experiencing suicidal thoughts and attempting suicide. Furthermore, protective factors such as school, parental, and peer connectedness were found to play a critical role in mitigating the adverse impacts of bullying and cyberbullying on suicidal thoughts and attempts. Conclusion: The findings underscore the critical prevalence of both bullying and cyberbullying among school-going Argentinian adolescents and their profound association with suicidal behaviors. The study emphasizes the importance of supportive family environments and peer and school connectedness in mitigating the negative effects of bullying and cyberbullying on mental health and suicide risk among adolescents.

Evaluation of heroin-assisted treatment in Norway: protocol for a mixed methods study.

BACKGROUND: Opioid agonist treatment (OAT) for patients with opioid use disorder (OUD) has a convincing evidence base, although variable retention rates suggest that it may not be beneficial for all. One of the options to include more patients is the introduction of heroin-assisted treatment (HAT), which involves the prescribing of pharmaceutical heroin in a clinical supervised setting. Clinical trials suggest that HAT positively affects illicit drug use, criminal behavior, quality of life, and health. The results are less clear for longer-term outcomes such as mortality, level of function and social integration. This protocol describes a longitudinal evaluation of the introduction of HAT into the OAT services in Norway over a 5-year period. The main aim of the project is to study the individual, organizational and societal effects of implementing HAT in the specialized healthcare services for OUD. METHODS: The project adopts a multidisciplinary approach, where the primary cohort for analysis will consist of approximately 250 patients in Norway, observed during the period of 2022-2026. Cohorts for comparative analysis will include all HAT-patients in Denmark from 2010 to 2022 (N = 500) and all Norwegian patients in conventional OAT (N = 8300). Data comes from individual in-depth and semi-structured interviews, self-report questionnaires, clinical records, and national registries, collected at several time points throughout patients' courses of treatment. Qualitative analyses will use a flexible inductive thematic approach. Quantitative analyses will employ a wide array of methods including bi-variate parametric and non-parametric tests, and various forms of multivariate modeling. DISCUSSION: The project's primary strength lies in its comprehensive and longitudinal approach. It has the potential to reveal new insights on whether pharmaceutical heroin should be an integral part of integrated conventional OAT services to individually tailor treatments for patients with OUD. This could affect considerations about drug treatment even beyond HAT-specific topics, where an expanded understanding of why some do not succeed with conventional OAT will strengthen the knowledge base for drug treatment in general. Results will be disseminated to the scientific community, clinicians, and policy makers. TRIAL REGISTRATION: The study was approved by the Norwegian Regional Committee for Medical and Health Research Ethics (REK), ref.nr.:195733.

Predictor of smoking cessation among school-going adolescents in Indonesia: a secondary analysis based on the transtheoretical model of behavioral change.

Introduction: This study elucidates the complex journey of adolescents toward smoking cessation, investigating the association of relevant demographic factors, advertising, promotion, anti-cigarette messages, and individual knowledge and attitudes with being in different smoking cessation stages. Methods: Utilizing data from the 2019 Indonesia Global Youth Tobacco Survey, this secondary analysis included adolescents who reported ever smoking. The Transtheoretical Model (TTM) guided the categorization of the outcome variable into three smoking cessation stages based on the responses to two questions related to the intention and timing of the smoking cessation. This included contemplation, action, and maintenance stages. Multinomial logistic regression analyzed the associations between each independent variable and being in each stage of smoking cessation. The study comprised 3596 Indonesian adolescents from grades 7-12, of which 2484 responded to two questions related to intention and timing of smoking cessation and were included in regression analysis. Results: Findings indicate that males and those aged ≥16 were predominantly in contemplation phase. Early smoking initiation, usage of other tobacco products, and exposure to various forms of smoke increased the likelihood of being in contemplation and action phases. Parental smoking, school smoking exposure, and second-hand smoke were significant contemplation phase predictors. Exposure to tobacco advertising was linked to an increased likelihood of being in contemplation and action phases, whereas anti-cigarette messages showed no significant impact. Awareness of cigarette and second-hand smoke harms reduced the odds of being in the contemplation phase, while enjoying smoking and willingness to accept cigarettes from friends increased the odds of being in contemplation and action phases rather than in maintenance phase. Conclusion: Addressing age, gender, cultural influences, environmental factors, and attitudes towards smoking through tailored interventions is vital for aiding smoking cessation in Indonesian adolescents. Strengthened tobacco control in schools and public places is recommended to bolster these efforts. Longitudinal studies are required to explore the evolving patterns of smoking cessation behaviors over time, enhancing our understanding of the factors influencing sustained cessation.

Prevalence and correlates of diabetes and impaired fasting glucose among adults in Afghanistan: Insights from a national survey.

Objectives: Afghanistan is experiencing an escalating burden of noncommunicable diseases, with diabetes and impaired fasting glucose being of particular concern. To explore the prevalence of diabetes and impaired fasting glucose and associated factors among adult Afghans. Methods: This cross-sectional study used secondary data from a nationally representative survey, conducted in 2018 in Afghanistan. A blood sample was collected from the fingertip and tested through a strip to measure blood glucose. The complex sampling design and sampling weights were accounted for in all analyses to produce representative estimates of the target population in Afghanistan. Results: Of 3890 Afghan adults aged 18-69 years who participated in this survey, 11.07% and 10.32% had diabetes and impaired fasting glucose, respectively. For overweight individuals with abdominal obesity, the risk for diabetes became significantly elevated, with an adjusted relative risk ratio of 2.12 (95% CI: 1.10-4.09). However, the most pronounced effect was observed among individuals classified as having obesity with abdominal obesity with an adjusted relative risk ratio of 2.54 (95% CI: 1.37-4.70). Moreover, high cholesterol level was significantly associated with both impaired fasting glucose (ARRR: 2.52, 95% CI: 1.55-4.12) and diabetes (ARRR: 4.12, 95% CI: 2.59-6.56), whereas high blood pressure was significantly associated with only diabetes (ARRR: 1.82, 95% CI: 1.16-2.86). Conclusions: This investigation provides critical insight into the prevalence of diabetes and IFG among Afghan adults aged 18-69 years. Relative to the global average, the higher prevalence observed calls for specifically designed interventions targeting individuals with cardiometabolic risk factors, such as elevated body mass index, abdominal obesity, hypertension, and hypercholesterolemia.

Perceived discrimination and its association with self-rated health, chronic pain, mental health, and utilization of health services among Syrian refugees in Norway: a cross-sectional study.

Background: There is a scarcity of research on discriminatory experiences and their association with health outcomes among Syrian Refugees in Norway. Thus, this study aims to examine the relationship between perceived discrimination, self-rated health (SRH), chronic pain, poor mental health, and healthcare utilization among Syrian refugees resettled in Norway. Methods: Cross-sectional data from the Integration for Health project were analyzed, including 154 Syrian refugees who resettled in Norway in 2018-19. Perceived discrimination, SRH, chronic pain, psychological distress, post-traumatic stress symptoms, and healthcare visits were assessed. Statistical analyses, including Poisson regression and multinomial logistic regression, were conducted. The significant statistical level was set at 0.05. Results: Approximately 30% of participants reported experiencing discrimination, with no significant associations between sociodemographic factors and perceived discrimination. Perceived discrimination was significantly associated with psychological distress (adjusted PR: 2.07, 95%CI: 1.21-3.55), post-traumatic stress symptoms (adjusted PR: 11.54, 95%CI: 1.25-106.16), and 4 or more psychologist visits (adjusted OR: 12.60, 95%CI: 1.72-92.16). However, no significant associations were found between perceived discrimination and SRH; pain symptoms, or general healthcare utilization. Conclusion: Experienced discrimination is highly prevalent and seems to be associated with mental health outcomes, but not clearly with SRH, pain, or general healthcare visits among Syrian refugees living in Norway. Efforts should focus on reducing discrimination, promoting social inclusion, and improving access to mental health services for refugees. Public awareness campaigns, anti-discrimination policies, and cultural training for healthcare professionals are recommended to address these issues and improve the well-being of Syrian refugees in Norway.

Ocular manifestations of COVID-19: A systematic review of current evidence.

Introduction: COVID-19 caused by SARS-CoV-2, commonly presents with symptoms such as fever and shortness of breath but can also affect other organs. There is growing evidence pointing to potential eye complications. In this article, we aim to systematically review the ocular manifestations of COVID-19. Methods: We conducted a systematic review to explore the ocular manifestations of COVID-19. We searched online databases including PubMed, Embase, Scopus, and Web of Science up to September 4, 2023. After a two-stage screening process and applying inclusion/exclusion criteria, eligible articles were advanced to the data extraction phase. The PRISMA checklist and Newcastle-Ottawa Scale (NOS) were used for quality and bias risk assessments. Results: We selected and extracted data from 42 articles. Most of the studies were cross-sectional (n = 33), with the highest number conducted in Turkey (n = 10). The most frequent ocular manifestation was conjunctivitis, reported in 24 articles, followed by photophobia, burning, chemosis, itching, and ocular pain. Most studies reported complete recovery from these manifestations; however, one study mentioned visual loss in two patients. Conclusion: In general, ocular manifestations of COVID-19 appear to resolve either spontaneously or with supportive treatments. For more severe cases, both medical treatment and surgery have been employed, with the outcomes suggesting that complete recoveries are attainable.

The Upper-gastrointestinal Endoscopic Findings of People Living with HIV: A Systematic Review.

OBJECTIVE: This article aimed to analyze upper endoscopic findings in the HIV patient population to elucidate the upper-gastrointestinal complications related to HIV infection. Gastrointestinal (GI) disorders in individuals living with HIV/AIDS exhibit diverse and often nonspecific manifestations, imposing substantial morbidity and mortality burdens. Endoscopic evaluation with biopsies is essential in the diagnosis and management of these conditions. Delayed treatment due to undetected GI abnormalities during endoscopic examinations can lead to poorer health outcomes. METHODS: This systematic review has determined the findings of upper-GI endoscopy of HIV-infected patients. Online databases of PubMed, Web of Science, Jisc Library Hub Discover, and Library of Congress have been searched using relevant keyword combinations. We have retrieved all the pertinent papers and reports published in English and screened them against inclusion/exclusion criteria for data extraction in two steps. First, titles/abstracts have been evaluated and then full-text screening has been performed by independent researchers. This study has adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) checklist. RESULTS: In this review, 24 articles have been included in the final analysis. The study has focused on the characteristics of participants and the findings of endoscopic evaluations. The participants of the study have been HIV-positive patients, and the majority of them have undergone endoscopy due to gastrointestinal symptoms. The biopsy regions primarily targeted have been observed to be the esophagus, stomach, and duodenum. The most common result of the biopsy specimens has been chronic active gastritis. CONCLUSION: To improve clinical practice, this systematic review sought to provide an up-to-date reference for upper gastrointestinal endoscopic findings of HIV-infected persons. Our results are in line with earlier research showing how effective endoscopy is for determining a precise diagnosis and directing care. The majority of HIV patients with gastrointestinal symptoms have been found to have opportunistic infections and persistent active gastritis as well as mucosal abnormalities of the upper gastrointestinal tract. Studies have shown that endoscopic and histological assessment can aid in the early detection and management of issues involving the upper gastrointestinal tract.

The effect of macronutrient and micronutrient supplements on COVID-19: an umbrella review.

BACKGROUND AND AIMS: A healthy diet play an important role in the prevention and even treatment of various diseases. Proper nutrition plays an important role in boosting of immune system. These include the consumption of macronutrients such as proteins, lipids, carbohydrates, and also micronutrients including vitamins. Here, we aimed to systematically review the effects of macronutrients and micronutrients on the prevention and treatment of COVID-19. METHODS: We searched the databases of PubMed, Scopus, Embase, and Web of Science on December 23, 2023. The records were downloaded into an EndNote file, the duplicates were removed, and the studies underwent a two-phase screening process based on their title/abstracts and full texts. The included articles were screened and underwent inclusion and exclusion criteria. We included the English systematic reviews and meta-analyses that concurred with the aim of our study. The selected articles were assessed by Cochrane's Risk of Bias in Systematic Reviews for the quality check. The data of the eligible studies were extracted in a pre-designed word table and were used for the qualitative synthesis. RESULTS: A total of 28 reviews were included in this study. Most studies have shown that micronutrients are effective in morbidity and mortality controlling in viral respiratory infections such as COVID-19 but some studies have shown that micronutrients are sometimes not effective in controlling severity. On the other hand, calcifediol was by far the most successful agent in reducing intensive care needs and mortality between studies. CONCLUSION: Individuals without malnutrition had a reduced risk of SARS-CoV-2 infection and severe disease. The administration of Vitamin D is effective in reducing the morbidity and mortality of COVID-19 patients. Patients with vitamin D deficiency were more prone to experience severe infection, and they were at higher risk of morbidities and mortality. Other micronutrients such as Vitamin A, Vitamin B, and Zinc also showed some benefits in patients with COVID-19. Vitamin C showed no efficacy in COVID-19 management even in intravenous form or in high doses.

The individual- and community-level women's empowerment and utilization of maternity care services in Afghanistan: a multilevel cross-validation study.

BACKGROUND: This study aimed to explore the relationship between women's empowerment and utilization of maternity care for married Afghan women aged 15-49 y in Afghanistan, assessing the convergence validity of the Survey-based Women's Empowerment Index in Afghanistan (SWEI-A). METHODS: The study used data from the 2015 Afghanistan Demographic Health Survey to examine the association of different domains of women's empowerment with the utilization of maternity care using multilevel Poisson regression at both individual and community levels. RESULTS: The utilization of maternity services was considerably higher among women with high scores compared with those with low scores in almost all domains of the SWEI-A, except for property owning, in which women with high scores appeared to have lower rates of utilization of such services compared with those with low scores. At the community level, those communities with high participation of women in the labor force were less likely to have adequate antenatal care (ANC), institutional delivery and postnatal care (PNC). Individual-level literacy was associated with higher utilization of ANC, institutional delivery and PNC, contrary to community-level literacy. CONCLUSIONS: Except for property owning, the high score in almost all other domains was associated with higher utilization of maternity care, which indicates an acceptable level of convergence validity for the developed index (i.e. the SWEI-A) in measuring women's empowerment among married Afghan women aged 15-49 y.

Current ART, determinants for virologic failure and implications for HIV drug resistance: an umbrella review.

OBJECTIVE: The purpose of this study is to investigate the incidence of determinants for virologic failure and to identify predisposing factors to enhance treatment efficacy. Tackling this global public health issue is the key to reducing the rate of virological failure and increasing the success of treatment for those living with HIV. METHODS: This umbrella review delves into various aspects of current anti-retroviral therapy (ART) which is the primary treatment for human immunodeficiency virus (HIV) infection. Comprehensive searches were conducted in online databases including PubMed, Embase, Scopus, and Web of Science, up to May 26, 2023. Following the screening and selection of relevant articles, eligible articles were included in the data extraction. This study adhered to the PRISMA guideline to report the results and employed the NIH quality and bias risk assessment tool to ensure the quality of included studies. RESULTS: In total, 40 review studies published from 2015 to 2023 were included. The bulk of these studies concurred on several major factors contributing to HIV drug resistance and virological failure. Key among these were medication adherence, baseline and therapeutic CD4 levels, the presence of co-infections, and the advanced clinical stage of the infection. CONCLUSION: The resistance to HIV drugs and instances of determinants for virologic failure have a profound impact on the life quality of those infected with HIV. Primary contributors to this scenario include insufficient adherence to treatment, decreased CD4 T-cell count, elevated viral levels, and certain treatment regimens. Implementing appropriate interventions could address these issues. Sub-Saharan Africa exhibits elevated rates of determinants for virologic failure, attributed to the delay in HIV testing and diagnosis, and late initiation of antiretroviral therapy (ART). It is essential to undertake further research aimed at enhancing the detection of resistance in HIV patients and mitigating viral failure by addressing these underlying causes.

The relationship of hip fracture and thyroid disorders: a systematic review.

Introduction: Bone density regulation is considered one of the systems affected by thyroid hormones, leading to low bone density that can result in pathologic fractures, including hip fractures. This review aimed to update clinicians and researchers about the current data regarding the relationship between hip fractures and thyroid disorders. Methods: English papers were thoroughly searched in four main online databases of Scopus, Web of Science, PubMed, and Embase. Data extraction was done following two steps of screening/selection using distinct inclusion/exclusion criteria. This study used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist and the Newcastle-Ottawa Scale (NOS) as bias assessment. Results: In total, 19 articles were included in the research. The risk of hip fractures in women with differentiated thyroid cancer (DTC) is higher than hip fractures caused by osteoporosis. Men with hyperthyroidism and subclinical hyperthyroidism are at higher risk for hip fracture. Also, a decrease in serum thyroid stimulating hormone (TSH) may be associated with an increased risk of hip fracture. Conclusion: Reaching a consensus conclusion regarding the association between subclinical thyroid dysfunction and hip fracture is not feasible due to the heterogenicity of evidence; however, there may be a higher risk of fracture in individuals with subclinical hyperthyroidism.

Suicidal behaviours and their correlates in school-going Lebanese adolescents: findings from a national survey.

BACKGROUND: Adolescent suicide is regarded as a serious phenomenon that affects the well-being of the youth. This study aims to investigate the prevalence of suicidal behaviours and their association with physical/psychological harm and substance use in a nationally representative sample of adolescents in Grades 7-12 in Lebanon. METHODS: Data from the latest Global School-Based Student Health Survey conducted in 2017 were used in this study. The prevalence and correlates of suicidal ideation and suicide attempts among those who had considered committing suicide, at least once, were explored. RESULTS: An estimated 13.45% of Lebanese adolescents, particularly females in Grades 7-12 had considered suicide at least once in the past 12 months. More importantly, almost half of them had attempted it at least once in the past 12 months. Those who frequently felt lonely or worried (previous year), were involved in physical fights or assaults (previous year), had been verbally or physically bullied (previous month), had missed more school days, experienced food insecurity, and had a history of substance abuse (marijuana, amphetamine, alcohol, and tobacco products) were more likely to exhibit suicidal behaviours. Parental support and older age at drug initiation appeared to be protective factors. DISCUSSION: The findings characterise the correlates of suicidal behaviours among school-going Lebanese adolescents and determine the attributes of the risk group susceptible to engaging in suicide attempts. Future interventions and policies should consider these attributes when monitoring target groups, particularly those with the alarming behaviours identified in this study. In addition, awareness campaigns that engage all stakeholders, particularly parents, should be prioritised by the authorities.

The Effectiveness of Face Masks in Preventing COVID-19 Transmission: A Systematic Review.

INTRODUCTION: Since the beginning of the COVID-19 pandemic, face masks have been among the cornerstones of COVID-19 prevention. Therefore, evaluating their preventive effects against COVID-19 is crucial. This review aimed to systematically search for the systematic review articles that explored the role of various types of face masks in preventing COVID-19. METHODS: We browsed the keywords of this study in the online databases of Scopus, Web of Science, PubMed, and Cochrane on 10th January 2023 and retrieved all the relevant systematic review articles. The records were downloaded into an Endnote file, and the duplicates were removed. A two-step screening process consisting of title/abstract and full-text screenings was conducted to select the most relevant articles. To ensure the validity and reliability of the results, this study adhered to the PRISMA protocol. RESULTS: A total of 28 systematic reviews were included in this review. Most studies found that face masks are beneficial against viral respiratory infections, such as COVID-19. Different types of masks were evaluated in included studies. It appeared that mask efficacy depends on the material, layers, fitting on the face and user compliance. N 95 respirator had maximum efficacy, especially when used continuously. CONCLUSION: Face masks have a beneficial effect against COVID-19. Home masks are less protective than surgical masks or N95 personal breathing masks. Besides, the use of masks may elicit a false sense of security in people, which may lead to poor hand hygiene and violation of social distancing. Therefore, the necessary training should be provided to the public to increase awareness and encourage the right practice of using the mask, emphasizing the preventive effects of washing hands, social distancing, and using a face mask against COVID-19.

Internal migration and utilization of reproductive and maternity care among women in Pakistan: evidence from a recent National Survey.

Background: During the last decades, migratory behavior has had a key role in population growth and redistribution in Pakistan. Migration has far-reaching socioeconomic implications for individuals and society at large that could influence the health integrity of Pakistani women. This study aimed to describe the migration patterns and drivers as well as their association with adequate access to reproductive and maternal care among married Pakistani women aged 15-49. Methods: The data from the 2017-18 Pakistan Demographic Health Survey (PDHS) was used to extract the information on the explanatory (sociodemographic and migration backgrounds) and outcome variables (unmet needs for family planning, adequate antenatal care, and delivery at health facilities). Bivariate and multivariate logistic regression analyses were employed to examine the relationship between these explanatory and outcome variables before and after adjustment for sociodemographic inequalities. Results: In unadjusted models, the odds of having adequate ANC and delivery at health facilities were approximately 2 to 4 times higher in those living (urban non-migrant), moving to (urban to urban, rural to urban), or leaving the urban areas (rural to urban) as compared to rural non-migrants; likewise, the odds of the unmet needs for family planning was about 20-50% lower in the same migration streams compared to rural non-migrant. However, after adjustment for sociodemographic inequalities, most of these associations attenuated and only the association of urban to urban migration with unmet needs for family planning and the association of urban non-migrant with delivery at health facilities remained significant. Conclusion: Although the findings suggest that Internal migration flows, particularly those to urban areas (urban to urban and rural to urban), could be associated with better access to reproductive and maternity care among married Pakistani women aged 15-49 years; adjustment for sociodemographic inequalities, particularly education and wealth, nullified this association to a great extent. This has important implications for current policies and interventions in Pakistan and calls for policy reform and women's rights advocacy to enhance the literacy level of young Pakistani girls through well-tailored interventions, maintaining them at school.

Intimate Partner Violence and Children Under 5 Morbidities and Mortality in Afghanistan: Findings From a National Survey.

Limited knowledge exists concerning the prevalence and drivers of intimate partner violence (IPV) against Afghan women and its association with child morbidity and mortality in Afghanistan. The study used data from the 2015 Afghanistan Demographic and Health Survey (ADHS 2015). The prevalence and associated sociodemographic factors of IPV were described by analyzing the data from Afghan women aged 15 to 49 years selected for the IPV module in ADHS 2015 (n = 24,070) whose children under 5 (n = 22,927) were included in the further analysis to estimate the morbidity and mortality of children and its association with IPV. It appeared that more than half of the Afghan women aged 15 to 49 years experienced IPV in the past year. Illiteracy (odds ratio [OR] = 1.69; 95% CI: 1.19, 2.39), living in rural areas (OR = 1.47; [1.19, 1.82]) being from the Pashtun, Tajik, Uzbek, and Pashai ethnic backgrounds were associated with a higher risk of IPV exposure. In general, the likelihood of child mortality within the first 5 years was higher among children born to mothers exposed to IPV, particularly physical and sexual even after adjustment for sociodemographic inequalities, the number of antenatal care, and marriage age. In addition, the odds of diarrhea, acute respiratory infection, and fever in the past 2 weeks were significantly higher among the children of victimized mothers in both adjusted and unadjusted models. Moreover, low birth weight and small birth size were more likely to be observed among the children of a mother who either experienced sexual or physical violence. The findings emphasized the elevated risk of morbidity and mortality among children under 5 born to mothers exposed to IPV and incorporating IPV screening into maternity and child care could reduce these adverse outcomes among Afghan women.

SARS-CoV-2 Infection and Severity in Patients with Hematologic Malignancies: A Systematic Review.

INTRODUCTION: Earlier reports described the possibility of higher SARS-CoV-2 infection and severity in patients with hematological malignancies. Given the importance and incidence of these malignancies, we aimed to systematically review SARS-CoV-2 infection and severity in patients with hematologic cancers. METHODS: We retrieved the relevant records by searching the keywords in online databases of PubMed, Web of Science, Cochrane, and Scopus on December 31st, 2021. A two-step screening; title/abstract and full-text screening, was employed to select the eligible studies. These eligible studies entered the final qualitative analysis. The study is adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist to ensure the reliability and validity of the results. RESULTS: Forty studies concerning different hematologic malignancies and the effect of COVID-19 infection on them were included in the final analysis. The findings showed that in general, the prevalence of SARS-CoV-2 infection and the severity of the disease are often higher in hematologic malignancies and the patients could experience higher morbidity and mortality compared to general populations. CONCLUSION: It appeared that individuals with hematologic malignancies are more vulnerable to COVID-19 infection and they experience more severe disease with higher mortality rates. The presence of other comorbidities could also deteriorate this situation. Further investigation is recommended to evaluate the outcome of COVID-19 infection in different subtypes of hematologic malignancies.

Post-Exposure Prophylaxis for COVID-19: A Systematic Review.

INTRODUCTION: SARS-CoV-2 cause pneumonia can spread across the lung and lead to acute respiratory distress syndrome (ARDS) in severe cases. Post-exposure prophylaxis has shown great potential to prevent the transmission of some viral infections; however, such results for COVID-19 are still inconclusive. METHODS: Therefore, the aim of this study was to systematically review the resources that utilized postexposure prophylaxis (PEP) for COVID-19 and the possible clinical benefits of such drugs. An organized search of relevant literature was done using the keywords and search queries on public databases of Cochrane, PubMed, Web of Science and Scopus from December 2019 to August 23, 2021. Original resources that had the inclusion criteria were included after two-phase title/abstract and full-text screenings. This review adhered to the Preferred Reporting Items for Systematic Reviews and Meta- Analysis (PRISMA) statement. RESULTS: Out of 841 retrieved records 17 resources were appropriate to include in the systematic review. Hydroxychloroquine with a daily dose of 400-800 mg and a duration of 5-14 days was the most frequently used agent for PEP. Chloroquine was recommended to use to control treatment in patients with mild to severe COVID-19 pneumonia. Other agents like Lopinavir-ritonavir (LPV/r), angiotensinconverting enzyme inhibitors (ACEIs), Angiotensin receptor blockers (ARBs), Vitamin D, arbidol, thymosin drugs, and Xin guan no.1 (XG.1, a Chinese formula medicine) have also been applied in some studies. CONCLUSION: Current evidence demonstrated no established clinical benefits of any drug as PEP in individuals with COVID-19. However, scarce indication occurs for the beneficial effects of some agents, but more studies are needed to explore such effects.
