Background: Air pollution is one of the major environmental risk factors for health. Children are vulnerable to the negative health consequences of air pollution. We aimed to determine the effect of PM10 levels on postneonatal mortality in Istanbul, the most populous city in Türkiye.

Methods: In this cross-sectional study, the relationship between PM10 levels and postneonatal deaths occurring in Istanbul, Türkiye in 2015-2019 was examined. PM10 levels for Istanbul were calculated by taking the average of daily PM10 measurements between 01.01.2015 and 31.12.2019, made available from Istanbul Air Quality Monitoring Stations. Data were analyzed using Microsoft Office Excel 2016 and AIRQ+ 2.2.3 software.

Results: If the PM10 value in Istanbul province had been reduced to 20 μg/m³, the limit value recommended by the WHO; in 2019; 36(19-61) postneonatal infant deaths could have been prevented; 7.73% (3.98-12.95) of postneonatal infant deaths were attributed to PM10. During this period, the PM10 value in Istanbul was above the limit value recommended by WHO, the European Union and Turkish legislation.

Conclusion: Infant mortality due to air pollution is an important public health problem.

Background: In the present review, we carried out a systematic review and meta-analysis to analyze possible lymph node metastasis (LNM) hazards in individuals with endoscopic resection of gastric cancer.

Methods: Relevant literature was selected by evaluating the PubMed, Cochrane Library, and Google Scholar electronic databases since from inception to March 2022. Corresponding clinicopathological outcomes were summarized, and pooled log odds ratios and 95% confidence intervals were assessed. The random effect model was preferred if variations among studies is high otherwise fixed effect model was preferred.

Results: Overall, 12 associated papers, including 4808 early gastric cancer individuals who endured more surgery after noncurative endoscopic resection, were entered into this analysis. The outcomes showed that submucosal invasion (log odd ratio 1.75, 95% (CI): 0.77-3.95, I² = 80.0%); vertical margin (log odd ratio 6.53, 95% (CI): 2.81-15.17, I² = 65%); horizontal margin (log Odd ratio 0.69 95% (CI): 0.22-2.14, I² = 52%), lymphatic invasion (Odd ratio 6.33 95% (CI): 1.98-20.24, I² = 91%), and vascular invasion (Odd ratio 3.55, 95% (CI): 1.31-9.58, I² = 92%) was significantly related to metastasis of lymph node for these patients.

Conclusion: There was a significant association of LNM hazards in individuals with endoscopic resection of gastric cancer. Therefore, invasion to lymph, vascular, submucosa and positive vertical margin should be strongly noticed when selecting surgical treatment factors.

Background: We aimed to assess the likelihood of cause-specific death and other causes of death after gastrectomy for gastric cancer (GC). Additionally, a competing-risk nomogram was developed for patient counseling and decision-making.

Methods: Eligible GC patients who had gastrectomy between 2007 and 2015 were included in the study from the Surveillance, Epidemiology, and End Results (SEER) database. Death from gastric cancer and death from other causes were considered as separate competing events. Cumulative incidence functions (CIF) were calculated for each event, and a competing-risk nomogram was developed.

Results: Overall, 8,808 patients who underwent gastrectomy were analyzed. Among them, 4,659 (52.90%) died from gastric cancer and 1,284 (14.58%) died from other causes. The five-year cumulative incidence of cause-specific death for gastric cancer was 50.4%, and 10.2% for deaths from other causes. Several independent factors, such as age at diagnosis, tumor site, grade, size, lymph node examination results, pathological T status, pathological N status, metastatic status, Lauren classification, radiation, and chemotherapy, were found to be associated with gastric cancer-specific death. The nomogram, based on results from the competing risk regression model, demonstrated good performance.

Conclusion: We have developed a nomogram aimed at predicting gastric cancer-specific mortality in patients following gastrectomy. The model has undergone internal validation, demonstrating good accuracy and reliability. It serves as useful tool that can assist physicians and patients in making more informed clinical decisions.

Background: With the intensification of population aging globally, the mental health of the elderly is not only related to their personal well-being but also directly affects family harmony and social stability. However, few studies have been conducted on interventions for mental health issues in the elderly.

Methods: From September to December 2023, a total of 164 elderly individuals were recruited from Ronghui Shanshui community in Fuzhou City of China through random cluster sampling and randomly divided into the control and experiment groups. The experiment group was given a three-month intervention based on general adaptation syndrome model, whereas the control group was given no intervention. At the end of the intervention period, an effect comparison was conducted between the two groups using the Physical Activity Rating Scale, University of California at Los Angels (UCLA) Loneliness Scale, and Memorial University of Newfoundland Scale of Happiness.

Results: After the intervention, the well-being of the experiment group increases significantly and is significantly higher than that of the control group (P < 0.05). After the intervention, the loneliness of the experiment group decreases significantly and is significantly lower than that of the control group (P < 0.05). Exercise participation significantly mediates the relationship between the intervention and psychological experience (P < 0.001).

Conclusion: This intervention model is not only beneficial for improving positive psychological experience in the elderly but can also effectively reduce their negative psychological experience. This study provides valuable reference for scientific intervention in the mental health of the elderly.

Background: We aimed to explore the prediction value of disulfidptosis-related long noncoding RNAs (lncRNAs) on the prognosis and immunotherapy efficiency of patients with head and neck squamous carcinoma (HNSCC).

Methods: Clinical and RNA-seq information were collected from The Cancer Genome Atlas (TCGA) and Genome Data Sharing (GDC) portal. The Pearson correlation analysis, univariate COX regression analysis, the least absolute shrinkage and selection operator (LASSO) COX regression were employed to construct the disulfidptosis-related lncRNAs (DRLs) prognostic model. The Kaplan-Meier survival curve, principal component analysis (PCA), receiver operating characteristic (ROC) curves and areas under the curves (AUCs) were used to examine the accuracy of the prognostic model. ssGSEA, mutation and functional and gene set enrichment analysis was performed to quantify the immune cell infiltration, immune function and functional enrichments. Finally, the mRNA expression of the DRLs was verified by real-time PCR (RT-PCR) in HNSCC cells.

Results: A new DRLs prognostic model (AC083967.1, AC106820.5, AC245041.2, AL590617.2, AP002478.1, and VPS9D1-AS1) with an independent prognostic value of HNSCC patients was successfully identified. In addition, the DRLs prognostic model was related with immune signature and drug therapy response. Meanwhile, the mRNA expression level of the 6 DRLs detected by RT-PCR was consistent with the results of bioinformatic analysis.

Conclusion: We developed a new DRLs prognostic model of HNSCC, which could effectively predicate the prognosis and therapy response of HNSCC patients and provide insights into personalized therapeutics.

Background: Acne vulgaris is a chronic inflammatory disease predominantly known as a disease of adolescents. We aimed to assess the quality of life of adolescents with acne in the territory of northern and southern regions of Montenegro.

Methods: This cross-sectional study was conducted in 2024, in four secondary schools in the north and south of Montenegro with total number of 561 subjects. To assess the quality of life of adolescents with acne we used the Children's Dermatology Life Quality Index and to measure acne-related disability we used The Cardiff Acne Disability Index.

Results: The average value of the total CDLQI score among adolescents from the northern region of Montenegro was 4.45±3.31, and 4.03±3.50 among southern region. The average value of the total CADI score among adolescents from the northern region of Montenegro was 3.56±1.77, and 3.50±1.98 among adolescents from the southern region. A statistically significantly higher mean value of sub scores in adolescents from the northern region compared to adolescents from the southern region existed in the domain of symptoms and feelings, vacation and treatment (P< 0.05). The regression analysis was also performed.

Conclusion: This study confirms the negative impact of acne on the quality of life of Montenegrin adolescents, especially those in the northern region. It is necessary to give more attention to the acne problems from doctors, and to increase awareness among adolescents and provide them early and the most effective therapy.

Background: Gestational diabetes mellitus (GDM) is a common complication of pregnancy that can lead to adverse outcomes. In this retrospective cohort study, maternal fasting blood sugar (FBS) in the second trimester of pregnancy, body mass index (BMI), and age were assessed as potential screening indicators of later GDM.

Methods: The study population included information on 4007 Iranian pregnant women documented by the Integrated Health Record System (SIB) record system (2019-2020).

Results: In the adjusted analysis, FBS maintained a significant relationship with GDM (P ≤0.001). In the simple ROC analysis, the AUC (SE) of FBS for the prediction of GDM was 0.905(0.09), and considering the cut-off point as 85.95, sensitivity (Se) and specificity (Sp) were equal to 0.81 and 0.71, respectively, but by stillbirth, abortion, prematurity, neonatal weight, height, and head circumference not obtained acceptable AUC (≥.60) for detection of FBS cut-off point. The cut-off point of FBS in the presence of maternal age (AUC>0.6) and BMI (AUC>0.6) by GDM was 83.75(Se= 86.4%, Sp= 80.0%).

Conclusion: Based on the evidence presented, maternal weight and BMI are important in predicting hyperglycemia leading to GDM. It is necessary to conduct more precise national studies to standardize the FBS cut-off point by controlling age and BMI variables.

Background: We aimed to review the effect of community-based health insurance on health-related outcomes in Ethiopia.

Methods: A systematic review was undertaken utilizing a major relevant published literature review from September 2017 to June 15, 2023. PubMed, Scopus, Web of Science, Science Direct, Google Scholar, Semantic Scholar, EMBASE, ProQuest, Hinari, and the Cochrane Library were used to search for relevant literature. Moreover, the Prisma flow model was used to select eligible findings.

Results: Overall, 72% of the articles employed cross-sectional comparative study designs and procedures, and 36% of them employed samples ranging in size from 501 to 1000 participants. Furthermore, 76% were studied using descriptive statistics and logistic regression, whereas fewer utilized a random model, a probity model, or a correlation model. Similarly, 32% of the research used two-stage stratified sampling methods, and around 40% of the data revealed that the scheme increased healthcare utilization services. About 72 % of the reviewed study results showed that the scheme reduced catastrophic health expenditure and increases utilization of healthcare services. And the 20% reviewed studies stated that the CBHI boosts household satisfaction level. Moreover 12% of the reviewed studies stated that, CBHI increased QoL (quality of life).

Conclusion: Most of the studies provide evidence of the positive effect of CBHI in Ethiopia. Mainly, its membership improved the utilization of health services and decreased the incidence of catastrophic health expenditures. Thus, all actors should cooperate to strengthen it to solve the effective attribute of the deprived value of health care and continuity of care delivery system related to the country's new policy.
