Background: The objectives of this review and meta-analysis were twofold: first, to determine the prevalence of substance use among school-going children in Arab and African countries; and second, to highlight the considerable influence of variables such as the nation's region and the timeframe of the study on the prevalence of substance use.

Methods: Research was sourced from Science Direct, Scopus, Web of Science, Google Scholar, and PubMed. Thirty-seven articles were incorporated in accordance with the PRISMA guidelines. This review included studies published from 2013 to 2023. The statistical meta-analysis was performed using Comprehensive Meta-Analysis ver. 3 software. Across 37 studies, the total number of study participants was 73,508.

Results: The meta-analysis revealed that tobacco was the most commonly used substance, with a prevalence of 16% (95% confidence interval [CI], 12.7%-20.02%). This was closely followed by alcohol, which had a prevalence of 15% (95% CI, 10.5%-22.8%), stimulants at 11.4% (95% CI, 7.4%-17%), khat at 10% (95% CI, 5.7%-15%), and cannabis at 8% (95% CI, 3.3%-18.4%). Notably, alcohol was the only substance that showed an increasing trend in prevalence from before to after 2019, rising from 13.3% (95% CI, 6.2%-26.1%) to 17% (95% CI, 10.2%-27%) (p<0.001). Additionally, the prevalence of substance use varied significantly between Arab and African countries (p<0.001).

Conclusion: Although the prevalence of substance use among school-going populations has significantly decreased over time, with the exception of alcohol, it is imperative that both African and Arab countries implement comprehensive measures and stringent laws to address the production and marketing of substances.

Background: Mortality statistics during the coronavirus disease 2019 (COVID-19) pandemic are crucial for the allocation of medical care resources and public health decision-making. This study was initiated to investigate the excess mortality among older adults during the pandemic. Our research focuses on 2 primary areas. First, we analyzed the cumulative excess mortality across all age groups to assess the global impact and specifically examined the top 20 countries with the highest mortality rates during the pandemic. Second, we explored excess deaths among older adults by categorizing data from the years 2020 and 2021 into age groups: 65-74, 75-84, and above 85.

Methods: We analyzed data from the top 20 countries with the highest mortality rates globally, focusing on 3 components: all-cause mortality means, expected deaths mean, and excess deaths mean for both older men and women.

Results: Although excess mortality is higher among older men and women across all 3 age groups (65-74, 75-84, and >85), the highest mean excess mortality was observed in women over the age of 85.

Conclusion: The results indicate that the severe acute respiratory syndrome coronavirus 2 virus had a disproportionately intense impact on older women. We developed 2 types of statistical models using the data: a binomial distribution model and a correlation coefficient model, both considering the mean excess deaths in older men and women across these 3 age groups. Estimating the excess mortality among older adults will aid in the formulation of healthcare policies for this demographic.

Background: The aim of this study was to disseminate information about the safety of bivalent coronavirus disease 2019 (COVID-19) mRNA booster vaccines administered to adults in the Republic of Korea.

Methods: Two databases were used to assess the safety of COVID-19 booster doses of Pfizer BA.1, Pfizer BA.4/5, Moderna BA.1, and Moderna BA.4/5 vaccines for adults aged 18 years and older. Adverse events (AEs) were analyzed using data reported to the web-based COVID-19 vaccination management system (CVMS) and a self-reported text-message survey.

Results: Between October 11, 2022 and March 30, 2023, the CVMS received reports of 2,369 (93.7%) non-serious AEs from vaccinated adults, along with 158 (6.3%) serious AEs, which included 5 cases of anaphylaxis and 33 deaths. From October 11, 2022 to January 27, 2023, 40,022 people aged 18 and older responded to a survey conducted via text message. The booster doses were associated with fewer local and systemic AEs compared to the original vaccines. After receiving the bivalent vaccine, the most commonly reported AEs were pain at the injection site, headache, fatigue, and myalgia.

Conclusion: Overall, bivalent vaccines exhibited fewer AEs compared to the original vaccines. The majority of AEs were non-serious, and serious AEs were rare among adults aged 18 years and older following vaccination with the Pfizer and Moderna bivalent vaccines.

Background: Polycystic ovary syndrome (PCOS) is a common, heterogeneous clinical syndrome affecting women. Investigating oxidative stress in women is crucial, as it is linked to insulin resistance and endothelial dysfunction. Chlorogenic acid, a bioactive component found in green coffee, has numerous documented health benefits. This study aimed to assess the beneficial effects of green coffee consumption on paraoxonase-1 (PON-1) activity and malondialdehyde (MDA) levels in women with PCOS.

Methods: This study was a double-blind randomized clinical trial that included 44 patients with PCOS. Participants were randomly assigned to either the intervention or control group. For 6 weeks, the intervention group (n=22) received 400 mg of green coffee supplements, while the control group (n=22) received 400 mg of a starch-based placebo. Anthropometric indices, dietary assessments, and physical activity levels were evaluated before and after the 6-week intervention period. Additionally, blood samples were collected for laboratory analysis.

Results: Supplementation with green coffee increased PON-1 levels by 3.5 units, a significant finding (p=0.038). Additionally, the intake of green coffee supplements significantly reduced blood cholesterol levels by 18.8 units (p=0.013) and triglyceride levels by 6.1 units (p=0.053). However, no significant differences were observed in the levels of MDA, high-density lipoprotein, low-density lipoprotein, fasting blood sugar, insulin, or homeostatic model assessment of insulin resistance as a result of the intervention.

Conclusion: Supplementation with green coffee alters PON-1 activity and cholesterol levels in women with PCOS. However, it has no significant impact on MDA levels or glycemic status.

Background: The main Brucella species causing human infections in the Republic of Korea is Brucella abortus, which uses cattle as its host. However, since 2014, Brucella melitensis, which uses sheep and goats as hosts, has also been identified. This study investigated whether a shift has occurred in the predominant species of Brucella pathogens.

Methods: Brucellosis is a class 3 infectious disease requiring mandatory reporting and registration in the Korea Disease Control and Prevention Agency's infectious disease surveillance system (http://is.kdca.go.kr). Cases from 2014 to 2023 were studied, and whole-genome sequencing analysis was conducted using BruMLSA21.

Results: Out of 51 patients, males (45 patients, 88.2%) were predominantly affected. Twenty-five patients (49%) came from the livestock industry, and within the livestock sector group, the route of infection occurred exclusively through contact (25/25, 100%), whereas in other occupations, it was split between contact (9/26 patients, 34.6%) and ingestion (8/26 patients, 30.8%). Among the 31 patients who underwent Brucella culture tests, B. melitensis was found to be more prevalent than B. abortus (14 patients, 45.2% vs. 11 patients, 35.5%). In all cases where B. melitensis was isolated, the infections were of foreign origin, consistent with the results of BruMLSA21.

Conclusion: Regular monitoring of the causative agent of brucellosis is necessary due to its varying host preferences and antibiotic resistance. Furthermore, given the increasing prevalence of B. melitensis worldwide, changes in dietary habits (e.g., increased lamb consumption), and the increase in foreign workers and Chinese immigrants, a multi-ministerial One Health response will be required.

Background: Malaria remains a serious public health challenge in tropical and subtropical regions, including Indonesia. Children under 5 years old face particular risk of contracting malaria due to low immunity. We examined potential factors associated with malaria infection among under-5 children in Papua Province, Indonesia.

Methods: The study utilized secondary data from Indonesia Basic Health Research 2018. Multistage random sampling was employed, from the province level to census blocks (CBs). In Papua Province, interviews were conducted in 928 CBs. All 2,745 under-5 children were selected. The dependent variable was laboratory-confirmed malaria positivity; independent factors included residential area, socioeconomic characteristics, and behaviors such as sleeping under an insecticide net impregnated ≤3 years ago and the use of ventilation barriers. We also examined the conditions of the bedroom, kitchen, and living room according to the frequency of window-opening, proportion of ventilation area to the floor, and radiance.

Results: Not sleeping under an insecticide net impregnated within the last 3 years (adjusted odds ratio [aOR], 0.518; 95% confidence interval [CI], 0.391-0.685; p<0.001); having a kitchen without windows (aOR, 0.491; 95% CI, 0.285-0.844; p=0.01); rarely opening the living room window (aOR, 2.804; 95% CI, 1.232-6.383; p=0.01), and having a windowless living room (aOR, 3.027; 95% CI, 1.369-6.696; p=0.01) displayed significant relationships with malaria infection among under-5 children.

Conclusion: Not using an insecticide-treated net impregnated ≤3 years ago, along with opening the living room window daily and having a kitchen without windows, appear preventive of malaria infection among under-5 children.

This study aimed to establish a foundation for future collaborations aimed at preparing for and responding to infectious diseases by examining the vaccine injury compensation programs (VICPs) of East Asian countries. We reviewed the current status of VICPs in the Republic of Korea, Japan, and Taiwan by searching national government websites and reviewing relevant literature. Additionally, we conducted email inquiries targeting experts from Japan and Taiwan. Through the comprehensive analysis of VICPs in these 3 countries covered various aspects, we identified several similarities and differences in the VICPs across these countries. While the governments of the Republic of Korea, Japan, and Taiwan play a central role in supporting investigations into vaccine injuries and managing compensation procedures based on legal statutes, they differ in terms of financial resources for compensation, the range of vaccines covered, and the criteria for assessing causality. In the Republic of Korea, Japan, and Taiwan, compensation is typically paid in a lump sum, although the specific benefits available vary by country. This study on VICPs in the Republic of Korea, Japan, and Taiwan provides valuable insights for the further development and management of domestic systems.

Background: This study investigated factors influencing intentional self-harm in Chungcheongbuk Province (hereinafter, Chungbuk) compared to Seoul in the Republic of Korea.

Methods: Raw data from the Discharge In-depth Injury Survey conducted by the Korea Disease Control and Prevention Agency were utilized. From 2,329,149 cases recorded over 9 years (2013-2021), 911 were identified as intentional self-harm cases (248 from Chungbuk and 633 from Seoul). We analyzed the differences in and influencing factors of intentional self-harm in Chungbuk relative to Seoul using the independent sample t-test, chi-square test, and binomial logistic regression analysis.

Results: Intentional self-harm was found to be 1.232 times more prevalent among females than males (p<0.05); 2.327 times more prevalent among middle-aged and older adults, ages 50 to 64, compared to those under 50 years old (p<0.01); 8.603 times more prevalent among those using hospitals with fewer than 500 beds compared to those with 500 beds or more (p<0.001); 2.412 times more prevalent among individuals using hospitals in different regions compared to those within the same region (p<0.01); 2.217 times more prevalent among those attempting intentional self-harm during daily activities compared to other specified activities (p<0.01); and 6.987 times more prevalent among those using pesticides or herbicides compared to other poisons (p<0.001) in Chungbuk relative to Seoul.

Conclusion: In the Chungbuk region, intentional self-harm prevention programs should be implemented, specifically targeting women, particularly those aged 50 to 64. Additionally, due to the high incidence of intentional self-harm involving pesticides or herbicides in Chungbuk, these substances should be stringently monitored to restrict access.

Background: The purpose of this study was to explore the relationships among obstructive sleep apnea (OSA), dyspnea, and health-related quality of life (HRQOL), as well as the factors influencing HRQOL.

Methods: A total of 129 lung cancer survivors (mean age, 53.4 years; 77 men and 52 women; mean time since diagnosis, 1.6 years; and cancer stage [1/2/3/4/relapse], 43/31/19/34/2, respectively) completed a questionnaire that included demographic and clinical information, as well as questions about the severity of sleep apnea, dyspnea, and HRQOL. The severity of OSA, dyspnea, and HRQOL were assessed using the Berlin questionnaire, the Dyspnea-10 item (FACIT-Dyspnea), and the European Organization for Research and Treatment of Cancer QLQ-C30, respectively.

Results: The severity of OSA and dyspnea exhibited negative correlations with HRQOL (p<0.05). Multiple regression analysis revealed that several factors significantly impacted the HRQOL of lung cancer survivors. These included the extent of dyspnea (β=-0.369, p<0.01), weight loss (β=0.192, p<0.01), OSA score (β=-0.215, p<0.01), stage 2 cancer (β=-0.181, p<0.01), and poor perceived health status (β=-0.179, p<0.05).

Conclusion: These findings suggest that breathing difficulties, including OSA and dyspnea, contribute to decreased HRQOL. This study offers valuable insights for researchers and clinicians, aiding in the development of effective strategies to manage these issues in daily life.
