Chad, a Sub-Saharan country, has some of the worst child mortality and health indicators. A lack of recent and accurate health records in Béré, rural Chad, due to decades of strife compromises the development of relevant health interventions by Project 21, a community health program. This study investigates child mortality, weight gain ability, and related factors in 0–2-year-olds through a cross-sectional study completed by trained community health workers using a survey questionnaire. Most household heads are Nangtchéré Christian males with secondary-level education. Male infants have the highest mortality rate. Infant mortality is predicted by non-exclusive breastfeeding started within 6 days after birth and by the number of household children who experienced and received treatment for meningitis. Toddlers’ mortality is predicted by the number of household adults who experienced and received treatment for meningitis and the number of household adults and children who were vaccinated. The odds of children having no difficulty gaining weight vary with their gender, age, the food or liquid given to them, the source of breastfeeding advice, handwashing and vaccination practices, and experiences with infectious diseases and their treatments. These findings provide targets for future health interventions towards achieving SDG3 in Sub-Saharan Africa. Full article

Kuwait has reported a problematic increase in the prevalence of Antimicrobial Resistance (AMR). However, the absence of studies that analyze AMR from combined human, agricultural (animal), and environmental domains limits our ability to assess the extent of the problem in Kuwait. Therefore, this systematic review provides a comprehensive insight into the AMR status in Kuwait regarding humans, agriculture (animals), and the environment from the perspective of the One Health approach. A systematic search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify the relevant literature on AMR in Kuwait. Multiple online electronic databases, including the Cochrane Library, Google Scholar, Web of Science, PubMed, BioMed Central (BMC), and Scopus, were searched to perform a narrative synthesis and meta-analysis. Twenty-eight studies published between 2009 and 2024 were included in this study. Domain-wise distribution varied, with 11 studies related to clinical settings, 11 to the environment, 4 to agricultural (animal), and 2 to both clinical and community settings. The narrative synthesis indicated a high occurrence of AMR bacteria in human, agriculture (animal), and environmental domains. In human domains, the dominant AMR isolates belonged to four Gram-negative species: E. coli, K. pneumoniae, P. aeruginosa, and Acinetobacter baumannii. In agriculture (animals), Salmonella isolates from poultry display high resistance to cefotaxime, ampicillin, and amoxicillin. Camel milk analyses revealed that 80% of bacterial isolates are resistant to antibiotics such as penicillin, tetracyclines, and carbapenems. An environmental analysis of sewage, seawater, sediment, and aerosol samples documented widespread antibiotic resistance genes (ARGs) with resistance mechanisms such as extended-spectrum beta-lactamase, carbapenemases, and colistin. The cross-domain analysis identified the overlapping of ARGs. Regarding the One Health approach, none of the studies used this approach to interlink these sectors. Meanwhile, the meta-analysis indicated a high resistance rate in humans (34.05%, 95% CI (22.81 to 46.27, p < 0.0001, I² = 98.94%)), agriculture (animals) (67.42%, 95% CI (30.30 to 94.93, p < 0.0001, I² = 97.40%)), and environment (69.86%, 95% CI (48.80 to 87.26, p < 0.0001, I² = 98.78%)). The reported spread of AMR and the overlap of resistance genes among isolates across the domains demonstrate the interconnected nature of AMR in Kuwait. These findings underscore the need to adopt the One Health approach to strengthen surveillance, implement control measures, and enhance public education strategies to address the complexity of AMR challenges in Kuwait.

This study investigated consumer perception of food insecurity by refining data collected from social media platforms. Text mining and TF-IDF were used to extract core keywords closely related to food insecurity and analyze their meanings. In addition, time series analysis and sentiment analysis were used to examine temporal and emotional changes. The analysis results showed that keywords, such as health, stress, mental, and depression, appeared frequently, indicating that food insecurity is closely related to psychological and mental problems. In addition, consumers showed high emotional sensitivity to essential nutrients, such as vitamin D, magnesium, calcium, and omega. Furthermore, stress indices and mental and physical response indices increased simultaneously during this period, indicating that food insecurity is a factor that causes emotional and physical responses. The results of the sentiment analysis showed that negative emotions (anxiety, fear, and sadness) were higher than positive emotions, suggesting that discussions related to food insecurity have a negative emotional impact.

Gestational complications, such as preeclampsia and gestational diabetes mellitus (GDM), pose significant risks to maternal and fetal health and increase long-term cardiovascular disease risk in offspring. This review aims to synthesize current knowledge on the roles of ferroptosis and neutrophil extracellular trap formation (NETosis)—two regulated cell death pathways—in these pregnancy-related conditions. We performed a comprehensive analysis of preclinical and clinical studies that investigate the involvement of dysregulated iron metabolism, oxidative stress, inflammation, and endothelial dysfunction mediated by ferroptosis and NETosis in gestational pathologies. Evidence indicates that disturbances in maternal iron homeostasis and enhanced formation of lipid peroxides and NETs contribute to placental dysfunction and systemic inflammation, exacerbating disease severity. Therapeutic strategies targeting these pathways are emerging but require further validation. Our review also identifies key gaps in mechanistic understanding, biomarker development, and translational research needs. We conclude that modulation of ferroptosis and NETosis offers promising avenues for improving diagnosis and treatment of pregnancy complications, though carefully designed clinical studies are essential to confirm their clinical utility and safety.

Ammonia is a common toxic pollutant in aquaculture environments that poses significant threats to the health, growth, and survival of aquatic organisms. This study investigates the physiological and molecular responses of triploid Crassostrea gigas to ammonia exposure, focusing on the activation and regulation of oxidative stress and immune-related pathways. By integrating histological observations, biochemical assays, and transcriptomic analysis, we systematically revealed the oxidative stress and immune regulatory mechanisms in the hepatopancreas of triploid C. gigas under ammonia exposure. Results showed significant tissue damage in the hepatopancreas, disrupted activities of key antioxidant enzymes including SOD, CAT, and GSH-Px, along with elevated MDA levels, indicating oxidative damage to cellular membrane lipids. Transcriptomic data further indicated significant activation of the glutathione metabolism pathway, with antioxidant genes such as GPX5 and GPX7 displaying a dynamic pattern of initial upregulation followed by downregulation, suggesting their critical roles in modulating oxidative stress responses and maintaining cellular homeostasis. Immunologically, ammonia exposure significantly activated lysosomal and phagosomal pathways, as well as multiple signaling cascades including FOXO, mTOR, and PI3K-Akt. Several key immune regulatory genes exhibited dynamic expression changes, reflecting coordinated regulation of apoptosis, autophagy, and energy metabolism to maintain immune defense and cellular homeostasis. Notably, dynamic expression of the GADD45 gene family in the FOXO signaling pathway underscores the important role of triploid C. gigas in mounting stress responses and adaptive immune regulation under ammonia toxicity. This study provides in-depth molecular insights into the integrated response mechanisms of triploid oysters to ammonia exposure, offering a molecular foundation for understanding bivalve adaptation to ammonia and revealing novel perspectives on molluscan ammonia tolerance.

The global outbreak of the monkeypox virus was declared a health emergency by the World Health Organization (WHO). During such emergencies, misinformation about health suggestions can spread rapidly, leading to serious consequences. This study investigates the relationships between tweet readability, user engagement, and susceptibility to misinformation. Our conceptual model posits that tweet readability influences user engagement, which in turn affects the spread of misinformation. Specifically, we hypothesize that tweets with higher readability and grammatical correctness garner more user engagement and that misinformation tweets tend to be less readable than accurate information tweets. To test these hypotheses, we collected over 1.4 million tweets related to monkeypox discussions on X (formerly Twitter) and trained a semi-supervised learning classifier to categorize them as misinformation or not-misinformation. We analyzed the readability and grammar levels of these tweets using established metrics. Our findings indicate that readability and grammatical correctness significantly boost user engagement with accurate information, thereby enhancing its dissemination. Conversely, misinformation tweets are generally less readable, which reduces their spread. This study contributes to the advancement of knowledge by elucidating the role of readability in combating misinformation. Practically, it suggests that improving the readability and grammatical correctness of accurate information can enhance user engagement and consequently mitigate the spread of misinformation during health emergencies. These insights offer valuable strategies for public health communication and social media platforms to more effectively address misinformation. Full article

Introduction: Major depressive disorder (MDD) is more prevalent in women, but men with MDD may experience higher suicide risk and a different symptom profile. This study investigates the subjective impact of MDD on health-related quality of life (HR-QoL) in males and females. Methods: A cross-sectional analysis was conducted on a representative sample from six Italian regions. MDD diagnoses were determined through semi-structured clinical interviews, and HR-QoL was assessed using the SF-12 questionnaire. Mania, hypomania, and subthreshold hypomanic symptoms were evaluated using the Mood Disorder Questionnaire (MDQ). Results: Women had a higher prevalence of MDD (6.2%) than men (3.5%). However, men with MDD showed significantly lower HR-QoL scores compared to non-depressed males, with a greater difference than that observed in women. No significant sex differences emerged in psychiatric comorbidities, but men showed a trend toward higher MDQ positivity, possibly indicating a different depressive phenotype. Conclusions: Although less frequently diagnosed in men, MDD appears to have a stronger perceived impact on quality of life in males. This finding may reflect under-recognized symptoms such as irritability, hyperactivity, and social rhythm dysregulation. Gender-sensitive screening and intervention strategies are essential to improve early detection and reduce the untreated burden of depression in men, ultimately supporting more equitable mental health outcomes.

This study investigated the molecular mechanisms by which phthalates induce depression, utilizing network toxicology and molecular docking techniques. By integrating the TargetNet, GeneCards, and PharmMapper databases, 658 potential target genes of phthalates were identified. Additionally, 5433 depression-related targets were retrieved from the GeneCards and OMIM databases. Comparative analysis revealed 360 common targets implicated in both phthalate action and depression. A Protein-Protein Interaction (PPI) network was constructed using the STRING database. Subsequently, the CytoHubba plugin (employing the MCC algorithm) within Cytoscape was used to screen the network, identifying the top 20 hub genes. These core genes include AKT1, CASP3, TNF, TP53, BCL2, and IL6, among others. Validation on the GEO dataset (GSE23848) revealed that the expression of multiple core genes was significantly upregulated in patients with depression (p < 0.05). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses indicated that phthalates mainly regulate biological processes such as extracellular stimulus response, lipopolysaccharide metabolism, and chemical synaptic transmission. Depression is mediated by the AGE-RAGE signaling pathway (a complication of diabetes), lipids and atherosclerosis, Endocrine resistance, and the PI3K-Akt signaling pathway. Molecular docking confirmed that phthalates have strong binding activity with key targets (CASP3, TNF, TP53, BCL2, IL6). These findings present a novel paradigm for evaluating the health risks posed by environmental pollutants. Full article

Studying the vertical and horizontal distribution of particulate matter at the hectometer scale in the atmosphere is essential for understanding its sources, transportation, and transmission and its impact on human health. In this study, a method was developed based on hyperspectral instrumentation to obtain both vertical and horizontal distributions of aerosol extinction by employing multiple azimuth angles, selecting optimized elevation angles, and reducing the acquisition time of individual spectra. This method employed observations from different azimuth angles to represent particulate matter concentrations in various directions. The correlation coefficient between the hyperspectral observations and in-situ measurement was 0.627. Observations indicated that the aerosol extinction profile followed an exponential decay, with most aerosols confined below 1 km, implying a likely origin from local near-surface emissions. The horizontal distribution indicated that the northeastern urban areas and the eastern rural areas were the primary regions with high concentrations of particulate matter. The observational evidence suggests the presence of two potential emission sources within the study area. Moreover, health risk results indicated that even within the same town, differences of particulate matter concentration and population density could lead to varying health exposure risks. For instance, in the 200° and 210° directions, which represent adjacent urban areas less than 1 km apart, the number of PM_2.5-related illness cases in the 210° direction was 20.83% higher than that in the 200° direction.

Objectives: Acute drug poisoning represents a significant public health issue among the pediatric population. The aim of this study was to evaluate the characteristics of drug poisoning in children and adolescents in the Vojvodina region from 2018 to 2023. Methods: In a retrospective observational study, 82 patients with confirmed drug poisoning were included, and data was collected regarding demographic characteristics, clinical manifestations, types of drugs involved, and the therapeutic interventions administered. The severity of poisonings was evaluated using the Poisoning Severity Score, and toxicological analysis was performed using gas chromatography–mass spectrometry. Results: The results indicated that poisonings were most prevalent in adolescent girls (72%), with 78% of cases resulting from intentional poisoning, while unintentional poisoning was more common in children. Benzodiazepines, antipsychotics, and analgesics were the primary drugs causing these poisoning incidents. The majority of patients (78%) experienced mild clinical symptoms, whereas 9% of pediatric patients suffered from severe poisoning, related to complications such as aspiration pneumonia and acute renal failure. Addressing pediatric drug poisoning in Vojvodina requires an increased focus on preventive strategies, including parental education and appropriate psychosocial support for the youth. Conclusions: Through collaborative efforts among healthcare providers, educators, and policymakers, prevention, treatment, and support mechanisms can be enhanced to combat this pressing public health challenge.

Background/Objectives: Age-related macular degeneration (AMD) is a leading cause of visual impairment in older adults and often coexists with cataracts. The indication of presbyopia-correcting intraocular lenses (IOLs) in these patients remains controversial. This study aimed to evaluate the clinical performance of a non-diffractive extended depth-of-focus (EDOF) IOL (LuxSmart™) compared to a monofocal plus IOL (Tecnis Eyhance™) in cataract patients with early-stage dry AMD. Methods: In this prospective observational study, 41 patients with early-stage AMD underwent bilateral cataract surgery with either LuxSmart™ or Tecnis Eyhance™ IOL implantation, targeting postoperative emmetropia. The eye selected for analysis was the first eye scheduled for surgery. Preoperative and postoperative evaluations included high and low-contrast distance visual acuity, intermediate and near visual acuity, defocus curves, ocular light scatter (halometry), and quality of life assessment (NEI VFQ-25). Postoperative biometric accuracy and refractive outcomes were also analyzed. Results: Both IOLs showed high refractive accuracy, with 100% of eyes within ±0.50 D of target. Postoperative uncorrected distance visual acuity was 0.10 ± 0.06 LogMAR for Eyhance and 0.07 ± 0.02 for LuxSmart (p = 0.06). Low contrast VA at 20% was 0.22 ± 0.11 (Eyhance) and 0.26 ± 0.16 (LuxSmart) (p = 0.49). Depth of focus was approximately 1.75 D for both lenses. Light scatter (LDI) improved postoperatively in both groups with no significant differences (p = 0.54). VFQ-25 scores showed improvement in daily activities, though no changes were observed in driving or mental health domains. Conclusions: Both lenses are safe and effective options for early AMD patients undergoing cataract surgery, providing good functional vision at multiple distances Full article

Obesity represents a significant global public health challenge, which not only elevates the risk of mortality but also increases the likelihood of chronic diseases. The ongoing obesity epidemic has led to a growing recognition of the detrimental effects of excessive adipose tissue accumulation on male reproductive health. Substantial evidence indicates that obesity adversely affects sperm quality, thereby impairing male fertility. Specifically, obesity is associated with compromised spermatogenesis, erectile dysfunction, and detrimental effects on offspring fertility parameters. These effects are mediated through various mechanisms, including alterations in the hypothalamic–pituitary–gonadal axis, inflammation within the reproductive system, localized caloric excess in reproductive tissues, epigenetic modifications, disruptions in gut microbiota, and heightened oxidative stress levels. While the molecular alterations associated with obesity have been extensively documented, the precise mechanisms by which obesity influences male reproductive function remain inadequately understood. This article aimed to review the classification and distribution of adipose tissue in obesity, the impact of obesity on male fertility, and the potential mechanisms through which obesity affects male reproductive health, thereby offering insights into the prevention and treatment of obesity-related male fertility issues.

The extensive utilization of amorphous silica nanoparticles (SiNPs) has raised concerns regarding the potential health risks. Previous studies have indicated that SiNPs could trigger both the activation of heat shock proteins (HSPs) and epithelial–mesenchymal transition (EMT) in BEAS-2B cells; however, the underlying mechanisms require further elucidation. This study aimed to investigate how SiNPs activate the heat shock response (HSR) in BEAS-2B cells, which subsequently triggers EMT. Firstly, we observed that SiNPs were internalized by BEAS-2B cells and localized in the endoplasmic reticulum (ER), inducing ER stress. The ER stress led to the activation of SIRT1 by phosphorylation, which enhanced the nuclear transcriptional activity of HSF1 via deacetylation. HSF1 was found to upregulate the levels of HSP70 and HSP27 proteins, which further affected EMT-related genes and, ultimately, induced EMT. Additionally, 4-phenylbutyric acid (4-PBA) inhibited ER stress, which attenuated the SIRT1/HSF1 signaling pathway. The knockdown of SIRT1 and HSF1 using siRNA effectively suppressed the EMT progression. In summary, these results suggested that SiNPs activated the SIRT1/HSF1/HSPs pathway through ER stress, thereby triggering EMT in BEAS-2B cells. The present study identified a novel mechanism of SiNP-induced EMT, which has provided valuable insights for future toxicity studies and risk assessments of SiNPs. Full article

Excessive alcohol consumption is associated with various health complications, including liver damage and systemic inflammation. Probiotic interventions have emerged as promising strategies to mitigate alcohol-induced harm, yet their mechanisms of action remain incompletely understood. This randomized, double-blind, placebo-controlled clinical trial aimed to evaluate the protective effects of Weizmannia coagulans BC179 in chronic alcohol consumers. Seventy participants with a history of long-term alcohol intake were randomly assigned to receive either BC179 (3 g/day, 1 × 10¹⁰ CFU) or a placebo for a 30-day intervention period. Following alcohol ingestion, dynamic monitoring of blood alcohol concentration (BAC), inflammatory and oxidative stress biomarkers, and serum metabolomic profiles was conducted. BC179 supplementation significantly reduced BAC and enhanced the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), while decreasing levels of alkaline phosphatase (ALP), high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6). Conversely, the anti-inflammatory cytokine interleukin-10 (IL-10), superoxide dismutase (SOD), and glutathione (GSH) were significantly upregulated. Levels of cytochrome P4502E1 (CYP2E1) and malondialdehyde (MDA) were also markedly reduced. Metabolomic analysis revealed significant modulation of taurine and hypotaurine metabolism, as well as downregulation of caffeine-related pathways. Collectively, these findings indicate that W. coagulans BC179 alleviates alcohol-induced discomfort by enhancing alcohol metabolism, attenuating inflammation, reducing oxidative stress, and modulating key metabolic pathways. This probiotic strain may represent a promising adjunctive strategy for managing alcohol-related health issues. Full article

School refusal behavior, defined as a child’s prolonged voluntary absence from school for reasons unrelated to illness and/or economic hardship, is a growing concern in Japan. The COVID-19 pandemic has worsened this issue by disrupting children’s lives. This review summarizes the prevalence, contributing factors, and health implications of school refusal, particularly in the context of COVID-19. A literature review of government reports and PubMed-indexed studies indicates that school refusal in Japan has been rising for eleven years, reaching a record 340,000 cases in 2023. Middle school students (6.7%) were the most affected, followed by elementary school students (2.1%). The pandemic intensified school-related, family-related, and child-related risk factors. School closures disrupted routines, reduced peer interactions, and increased social isolation, contributing to higher rates of anxiety and depression. Reports of suicides and mental health disorders among children have also surged. Family stressors, including economic hardship and parental mental health struggles, further exacerbate school refusal. Additionally, remote learning has widened socioeconomic disparities in access to education, leaving vulnerable children at greater risk. Addressing school refusal requires a multifaceted approach involving schools, families, healthcare providers, and policymakers. School-based interventions, mental health approach, and flexible educational programs would be essential. The Japanese government’s “COCOLO Plan” represents progress toward a more inclusive education system, and a comprehensive, interdisciplinary strategy is needed. Ensuring all children receive the necessary support to reengage with education is critical to overcoming the long-term challenges posed by school refusal. Full article
