Background: Daily energy intake from snacking behaviors has increased over the past few decades, during which the prevalence of obesity and metabolic syndrome has risen to epidemic proportions. There remains considerable room for improvement in the overall quality of dietary intakes of the U.S. population when compared to national recommendations. Food cravings may contribute to the types of snacks chosen for consumption, and thus, the frequency of foods and food groups consumed, and the overall nutritional quality of the diet. Methods: Eighty-four young (28.5 ± 4.3 years) adults with at least one metabolic syndrome risk factor participated in a parallel-arm single-blind randomized trial designed to compare effects of consuming a mix of tree nuts versus typical high-carbohydrate food items as between-meal snacks for 16 weeks. Cravings for 28 common foods via the Food Craving Inventory, short-term dietary intakes via 24 h multi-pass methodology, food group frequency via the Rapid Eating Assessment for Participants, usual hunger and fullness via visual analog scales, appetite-regulating hormones, and diet quality via the Healthy Eating Index—2015 were measured at baseline and end of study. Results: Participants in the TNsnack group had significant decreases in cravings for high sweet items and fast-food items, which were associated with decreased frequency of desserts and salty foods along with increased intake of higher protein items. In contrast, no significant reductions in food cravings or preference for sweets were observed in the CHOsnack group. Decreased cravings for sweets by TNsnack participants were associated with increased total GLP-1 levels: cake (r = −0.35, p = 0.03), brownies (r = −0.44, p = 0.02), candy (r = −0.36, p = 0.03) and ice cream (r = −0.33, p = 0.04). Overall, the total diet quality score improved by 19% among TNsnack participants. Conclusions: Replacing more typical between-meal snacks with tree nuts may reduce food cravings, particularly for sweeter food items that are likely to be nutrient poor and energy dense. By reducing cravings and frequency of intake, consuming tree nuts as snacks could facilitate having a higher quality, more nutrient-dense diet and mitigate potential negative effects of snacking on metabolic health in young adults.

Objectives: To estimate the prevalence, clinical characteristics, and risk factors of IgE-mediated food allergy (FA) in adults from northwestern Mexico. Methods: A population-based, cross-sectional study was conducted in Culiacán, Sinaloa. A validated questionnaire was administered to 834 adults (valid response rate: 87.5%) in public spaces. Prevalence rates (95% CI) were calculated, and associations were analyzed using odds ratios (OR). Results: The prevalence rates of “current immediate-type FA”, “food-induced anaphylaxis” and adult-onset “current immediate-type FA” were 5.75% (4.27–7.49), 2.5% (1.75–4.10) and 2.99% (1.94–4.39), respectively. The most common allergens were shellfish (2.14% (1.28–3.39)) and milk (1.19% (0.57–2.19)). Epinephrine was prescribed in 9.5% of the cases with anaphylaxis history. General practitioners made the diagnosis of 63.4% of the FA cases. FA was associated with personal and family history of atopy. Conclusions: Adult FA is frequent in the population studied and could be an emerging public health problem, characterized by a high rate of adult-onset cases and suboptimal management of anaphylaxis.

The increasing prevalence of neurological disorders highlights the need for disease animal models to elucidate the underlying biomolecular and cellular mechanisms of disease and to facilitate studies aimed at developing effective treatments. The fruit fly Drosophila melanogaster, at both larval and adult stages, can serve as an effective model for different human-relevant neurological diseases. Larvae are particularly suited for studying peripheral nervous system disorders, such as Charcot–Marie–Tooth and amyotrophic lateral sclerosis, while adults enable investigations of higher-order cognitive functions and age-related conditions, including Parkinson’s disease and depression-like behaviours. Combining larval and adult models offers a complementary framework to dissect the biomolecular pathways of neurological disorders and accelerate preclinical research. Full article

Background/Objectives: Diabetes mellitus is increasingly prevalent among adults aged over 80 years; however, this population remains substantially underrepresented in clinical research on diabetes complications. This scoping review synthesises current evidence on diabetes-related complications and comorbidities in this older age group (>80 years), reported prevalence, and key evidence gaps. Methods: A systematic search of MEDLINE, Embase, and Web of Science was conducted for studies published between 1992 and 2024 reporting diabetes-related complications in individuals aged ≥80 years. Two reviewers independently screened titles, abstracts, and full texts. Data were extracted and summarised using narrative synthesis, and descriptive statistics (SPSS v29) were conducted. Results: Fifty-one studies were included, comprising 17,630,083 individuals aged ≥80 years. Macrovascular complications were most frequently reported, followed by microvascular and peripheral outcomes. Hypertension was the most reported comorbidity. Macrovascular outcomes were assessed in over 17 million individuals, while microvascular complications were studied in fewer than 400,000. Only five studies focused exclusively on adults aged ≥80 years. Reporting was also limited by retrospective designs, heterogeneity in definitions, and frequent omission of key variables, including diabetes duration, HbA1c, frailty, and cognitive status. Conclusions: There is a critical mismatch between research focus and the complications most relevant to function and quality of life in older populations with diabetes. Easily measurable yet clinically impactful outcomes, such as retinopathy, neuropathy, nephropathy, and foot disease, remain under-investigated in this cohort. Standardised, age-stratified reporting that incorporates functional and geriatric domains is needed to inform person-centred care in this expanding population. Full article

Background/Objectives: This study examined the specific vulnerabilities and experiences of persons with disabilities (PwDs) regarding sexual violence (SV) in Belgium. Methods: Data were drawn from the nationally representative UN-MENAMAIS survey (n = 4944), which included adults aged 16–99 years. SV was assessed using behaviourally specific questions based on validated international instruments. Logistic regression analyses examined associations between SV, disability status, sociodemographic, and mental health indicators. Results: PwDs reported a significantly higher lifetime prevalence of hands-on SV (37.8%) compared with those without disabilities (29.4%; p < 0.001, V = 0.065). PwDs also reported lower quality of life (p < 0.001, V = 0.273), and higher rates of depression (p < 0.001, V = 0.214), anxiety (p < 0.001, V = 0.145), PTSD (p < 0.001, V = 0.101), sedative use (p < 0.001, V = 0.237), and suicide attempts (p < 0.001, V = 0.124), though they reported less hazardous alcohol use (p < 0.001, V = 0.103) and cannabis use (p < 0.001, V = 0.080). Regression analyses showed that individuals assigned female at birth (p < 0.001) and those identifying as LGB+ (p < 0.001) were at a higher risk of both hands-off and hands-on SV. Among mental health correlates, depression, anxiety, PTSD, substance use, self-harm, and suicide attempts were significantly (all p < 0.001) associated with increased odds of SV. Conclusions: The findings highlight the need for targeted, inclusive prevention and support strategies addressing structural inequalities, ableism, and barriers to care to effectively prevent SV and revictimization among PwDs.

Background/Objectives: Hypertension (HTN) is highly prevalent among middle-aged and older adults in Saudi Arabia, affecting nearly half of those attending primary care clinics. This growing burden contributes not only to cardiovascular disease, but also to functional decline and reduced mobility in aging Saudis. The objective of this paper was to examine the relationship between HTN and objective measures of mobility and endurance in Saudi adults aged ≥50 years, and to assess whether any associations differ by sex. Methods: In a cross-sectional study, 47 hypertensive and 53 non-hypertensive (no chronic disease) community-dwelling adults were recruited from various regions of Saudi Arabia. Participants completed mobility tests (five repetitions of sit-to-stand (5×STS) and timed up-and-go (TUG)) and an endurance test (6 min walk test (6MWT)). Multivariable linear regressions adjusted for age, body mass index, and sociodemographic factors were used to evaluate the association of HTN with each performance measure in men and women separately. Results: Participants with HTN were older (mean 63 vs. 57 years) and had higher BMI than controls (p < 0.05), as well as performing worse on all functional tests: they required more time for 5×STS and TUG, and walked a shorter distance during the 6MWT (all p ≤ 0.003). In sex-stratified analyses, HTN was associated with slower TUG in men (≈2 s longer, p = 0.027), while among women, HTN predicted significantly slower 5×STS (+8.4 s) and TUG (+2.8 s) times, and a 114 m-shorter 6MWT distance (p < 0.05 each). Conclusion: HTN is linked to impaired mobility and endurance in middle-aged and older Saudi adults, with hypertensive women exhibiting particularly pronounced deficits. Future research is needed to determine whether incorporating routine functional assessments and exercise-based counseling into HTN care may help identify and address early declines in physical independence among aging adults.

Background: The high prevalence of anxiety and depression among young adults constitutes a significant public health concern, with body image identified as a key psychological factor. However, the interplay between subjective metrics (perceived body image) and objective measures (Body Mass Index) remains insufficiently explored within specific populations, such as health sciences students in Eastern Europe. Methods: An observational, cross-sectional study was conducted on a sample of 137 medical and nursing students from a Romanian university. Validated instruments were employed: the Hospital Anxiety and Depression Scale (HADS) and the Eating Disorder Examination Questionnaire (EDE-Q). BMI was calculated from self-reported height and weight. Spearman’s correlation analyses and Mann–Whitney U tests were performed. Results: Subjective body image concerns, particularly those related to shape, weight, and eating, were found to be positively and significantly correlated with symptoms of anxiety and depression (all p < 0.05). In contrast, BMI exhibited no significant correlation with either of the HADS subscales. Although nursing students presented a higher mean BMI, no significant differences were recorded between the student groups with respect to psychological symptoms or body image concerns. Conclusions: Subjective dissatisfaction with body image is a more salient correlate of emotional distress than objective body mass in this cohort. Although the sample size was moderate, the observed associations were robust and statistically significant, underscoring the importance of subjective body image over objective metrics such as BMI in this academic population. These findings underscore the necessity for mental health interventions within university settings to focus on the perceptual and cognitive-affective aspects of body image, rather than exclusively on weight management.

Background: Diabetic ketoacidosis (DKA) is a serious acute complication of diabetes mellitus (DM) associated with significant morbidity, mortality, and healthcare burden worldwide. This study aimed to investigate population descriptors and clinical outcomes among adult and pediatric patients admitted with DKA at two tertiary medical centers in Riyadh, Saudi Arabia. Methods: We conducted a retrospective observational study that included adult and pediatric (≤15 years) patients admitted to emergency departments (EDs) and received care for DKA between 2018 and 2021. DKA severity was defined according to the American Diabetes Association (ADA) criteria, which rely on arterial/venous pH and serum bicarbonate (with anion gap supportive), as follows: mild (pH 7.25–7.30; HCO₃⁻ 15–18 mmol/L), moderate (pH 7.00–7.24; HCO₃⁻ 10–15 mmol/L), and severe (pH < 7.00; HCO₃⁻ < 10 mmol/L). Data were extracted from electronic medical records and analyzed descriptively. Results: A total of 373 patients were admitted to the EDs and received treatment for DKA throughout the study period. Adults constituted 71.6% (267/373), while children represented 28.4% (106/373) of the patients; the majority of adults (74.2%) had Type 1 DM (T1DM), while all pediatric patients had T1DM. More than half of the adult presentations met the criteria for severe DKA (55.8%; 149/267), whereas pediatric cases were most commonly moderate in severity (41.5%; 44/106). The most common precipitating factors across both age groups of patients with diabetes before the index DKA event were non-compliance with therapy and infection. Both groups demonstrated typical biochemical features of DKA, although pediatric patients presented with slightly lower bicarbonate and higher anion gaps (slightly greater metabolic acidosis) but with similar hydration status. Regarding patients’ outcomes, hyperkalemia was identified in 23.6% of adults and 24.5% of pediatric patients, while hypokalemia was documented in 20.2% of adults and 24.5% of pediatric patients, and adult patients experienced more acute kidney injuries than the other cohort (5.2% vs. 1.9%). In-hospital mortality was 0.8% (3/373) among all adults. Although pediatric patients experienced faster DKA resolution (median = 16.5 h; IQR, 11.7–25.8) compared to adult patients (23.7 h; 16.2–36.9), they had a longer hospital stay compared to adult patients, and a significant majority required ICU care (50.9%) at some point during their care. Conclusions: The increasing prevalence of DM in Saudi Arabia, especially among the youth, would lead to an increase in DKA burden unless effective preventive measures are taken. This study demonstrated that preventable causes, such as non-compliance with therapy and infection, were responsible for the high admission rates. Thus, comprehensive outpatient care can help strengthen care continuity and help decrease the burden on emergency and inpatient services. Full article

Since the emergence of COVID-19, the epidemiological and seasonal patterns of respiratory pathogens have shifted, highlighting the need for ongoing surveillance. This study investigated the epidemiology, seasonal trends, and age-specific detection of respiratory viruses among patients with acute respiratory infections (ARIs) in Thailand from January to December 2024. Eight respiratory viruses were detected using multiplex real-time RT-PCR. Of 7853 samples, 60.8% (4777) tested positive. The most frequently detected pathogens were influenza virus (IFV, 24.8%), SARS-CoV-2 (21.5%), and human rhinovirus (HRV, 20.8%). IFV showed biannual peaks during the cold and rainy seasons, SARS-CoV-2 peaked in the warm months, and HRV circulated year-round. Respiratory syncytial virus (RSV) and human metapneumovirus (HMPV) were primarily detected during the rainy season (July–November), reflecting a return toward pre–COVID-19 seasonal patterns. Age-specific differences were notable: HRV was most prevalent in children < 5 years, IFV predominated among those aged 6–18 years, and adults ≥ 19 years were mainly positive for IFV and SARS-CoV-2. Co-infections were most frequent in children aged 3–5 years, often involving HRV. These findings provide updated insights into post–COVID-19 viral epidemiology, emphasize the importance of age- and season-specific surveillance, and support the development of effective public health strategies for ARI control.

Polypharmacy and the use of potentially inappropriate medications (PIM) are prevalent issues among institutionalized older adults, contributing to adverse drug events and decreased quality of life. This study aimed to describe the sociodemographic and clinical characteristics associated with polypharmacy and the use of PIM in elderly people in nursing homes. A cross-sectional descriptive study was conducted among 151 residents aged ≥ 65 years. Data was extracted from institutional records. The mean age of participants was 86.48 ± 8.00 years; 71.5% were female. Excessive polypharmacy was observed in 49.7% of residents. The mean number of medications was 9.66 ± 4.18, with nervous system drugs being the most prescribed (3.73 ± 2.31). PDDIs were detected in 94% of the sample and PIMs were present in 82.8% of residents. The most common PIMs were proton pump inhibitors (ATC A) and anxiolytics (ATC N). Binary logistic regression identified two independent predictors for PIMs: the total number of medications (AOR = 1.259) and the use of ATC A (Alimentary tract and metabolism) medications (AOR = 2.315). Conversely, age and sex were not significant predictors. The study reveals a critical prevalence of excessive polypharmacy, PIM use, and PDDIs among institutionalized elderly in the Algarve. These findings underscore the urgent need for systematic, multidisciplinary medication reviews in Portuguese nursing homes to promote safer and more rational prescribing practices. Full article

Background/Objectives: Hepatitis B virus (HBV) remains a significant diagnostic and public health challenge worldwide. Despite widespread vaccination, underdiagnosis persists among adults in Saudi Arabia. This study estimated HBV prevalence and identified sociodemographic, clinical, and behavioral predictors relevant to improving targeted diagnostic screening. Methods: A cross-sectional study of 1196 Saudi adults aged ≥18 years was conducted between September 2024 and February 2025 using a structured questionnaire. Data on demographics, clinical history, and behavioral exposures were analyzed using chi-square tests and multivariate logistic regression to identify independent determinants of HBV infection. Results: The study included 1196 adults (60.0% female, mean age 31 ± 12 years). HBV prevalence was 2.0% (95% CI: 1.3–3.0%). Independent predictors included divorced/widowed marital status (OR = 3.99, p = 0.023), diabetes mellitus (OR = 3.59, p = 0.039), family history of HBV (OR = 2.55, p < 0.001), and massage exposure (OR = 3.99, p = 0.025). No significant associations were found with gender, education, or transfusion history. Conclusions: HBV infection persists among high-risk Saudi adults despite immunization success. Integrating HBV testing into diabetes care, premarital and household screening, and regulation of personal care services may enhance early diagnosis and advance national elimination goals.

Background/Objectives: Intracerebral hemorrhage (ICH) is primarily a disease of older adults, commonly linked to chronic hypertension and cerebral amyloid angiopathy. In young adults, however, ICH is rare and often driven by distinct structural, hematologic, or vascular causes. Methods: Using the National Inpatient Sample (2016–2022), we identified hospitalizations with a primary diagnosis of ICH (ICD-10-CM: I61.x). Patients younger than 18 years were excluded. Patients were stratified into 18–39 vs. ≥40 years. Comorbidities were defined using validated ICD-10 codes (E08–E13 for diabetes mellitus, I10–I15 for hypertension), excluding transient hyperglycemia (R73.x). Weighted analyses using NIS discharge weights compared demographics, comorbidities, rare etiologies, and outcomes, including in-hospital mortality, length of stay (LOS), and total hospital charges. Survey-weighted multivariable logistic regression identified independent predictors of mortality. Results: Among 76,264 ICH hospitalizations, 4012 (5.3%) occurred in patients < 40 years. Compared with older adults, younger patients had lower prevalence of hypertension (47.8% vs. 84.1%) and diabetes (10.2% vs. 60.4%) but higher rates of substance use (27.7% vs. 15.6%). Rare etiologies were more frequent, including arteriovenous malformation/aneurysm (14.0% vs. 3.6%), Moyamoya disease (1.4% vs. 0.2%), sickle cell disease (1.1% vs. 0.1%), and pregnancy-related ICH (0.05%). In-hospital mortality was lower among young adults (15.7% vs. 21.7%, p < 0.001), though LOS was longer (12.1 vs. 8.7 days, p < 0.001), and mean hospital charges were higher ($228,000 vs. $125,000, p < 0.001). Conclusions: Young-adult ICH is uncommon but etiologically distinct, often associated with vascular malformations, hemoglobinopathies, and substance use. Despite lower mortality, these patients experience longer and more resource-intensive hospitalizations, underscoring a substantial clinical and economic burden. Full article

Background/Objectives: The prevalence of Hepatitis C Virus (HCV) among men who have sex with men (MSM) is not negligible; however, data from Italy—especially regarding MSM who are not infected with Human Immunodeficiency Virus (HIV)—are limited. We report data from an HCV screening programme targeted at MSM in Rome, starting in 2019 in two hospital settings and in four urban community-based (CB) settings run by non-governmental organizations (NGOs). Methods: Adult MSM (>18 years old) who presented for HIV or sexually transmitted infection testing, or who attended CB activities, were invited to undergo a free-of-charge rapid HCV antibody test (OraQuick HCV^®), after providing informed consent. For all participants, demographic, clinical and behavioural data were collected using an anonymous questionnaire for all participants. Free confirmatory standard serology tests were offered for those found reactive at a rapid HCV test. Individuals with confirmed chronic HCV infection were referred through a dedicated “fast track” pathway for further clinical and laboratory assessment and direct-acting antiviral agents (DAAs) treatment according to the national treatment guidelines. Results: Between July 2019 and July 2023, 2714 MSM agreed to be screened for HCV infection. The median age was 36 years (interquartile range, IQR = 29–46), 91.0% were Italians, 58.0% enrolled in the two clinical centres and 10.7% reported living with HIV (people living with HIV, PLWH). Overall, 9 (0.33%) MSM tested reactive for HCV-specific antibodies using a rapid test. Eight MSM were retested and seven were confirmed to have chronic HCV infection (HCV viremia range: 8 × 10³–23 × 10⁶ IU/mL). The prevalence of confirmed cases was 0.26% (7/2714; 95%CI: 0.10–0.53) and was higher in PLWH compared to those not reporting HIV infection (1.04% vs. 0.17, p = 0.03). Four of seven confirmed HCV cases attended the STI clinic. All confirmed HCV cases reported high-risk behaviours for HCV infection and/or history of sexual transmitted infection (STI). Bening a PLWH (OR = 6.30) and current/former IDU (O = 17.02) resulted in being significantly associated with HCV infection. Other risk factors such as fisting, groupsex, chemsex and condomless anal intercourse were more common in the HCV case (OR > 2), but lacked statistical significance, likely due to small sample size. All seven individuals were linked to care, clinically assessed and started on DAAs treatment, achieving sustained viral response (SVR) in all cases. Conclusions: These data suggest the feasibility and potential effectiveness of a preventive programme targeting MSM living in Rome, combining HCV screening, case finding and prompt linkage to care. HCV prevalence in the screened population was lower than anticipated, although it is significantly higher in PLWH and in those with high-risk behaviours. Considering this condition of low prevalence of HCV infection among MSM in Italy, a targeted screening in PLWH and in individuals with high-risk behaviours may be more effective to achieve HCV eradication than universal screening in MSM.

Background and Aims: Given the high prevalence of chronic liver diseases, non-invasive assessment of liver fibrosis is critical for screening and management of these conditions. While the FIB-4 index is widely used, its age-dependent nature may reduce specificity in older adults. The FIB-3 index, which excludes age, has been proposed as an alternative. This study aimed to compare the diagnostic performance of FIB-3 and FIB-4 for detecting advanced fibrosis across age groups using magnetic resonance elastography (MRE) as the reference standard. Methods: We retrospectively analyzed 3424 patients aged ≥30 years with chronic liver disease who underwent MRE. Advanced fibrosis was defined as liver stiffness ≥ 3.62 kPa. The cutoff values and diagnostic performance of the FIB-4 and FIB-3 indices for advanced fibrosis were evaluated within subgroups stratified by age quartiles (Q1–Q4), and the areas under the ROC curves (AUROCs) were compared using DeLong’s test. Results: Both FIB-3 and FIB-4 indices demonstrated comparable diagnostic accuracy for advanced fibrosis (AUROC 0.82 (95% CI: 0.81–0.83) for both; p = 0.70). In age-stratified analysis, the cutoff values for the FIB-4 index increased with increasing age (Q1: 1.72, Q2: 2.90, Q3: 3.66, Q4: 4.20), reflecting its age-dependent formula. In contrast, the FIB-3 index exhibited relatively minor variation in cutoff values across quartiles (Q1: 2.32, Q2: 3.52, Q3: 3.74, Q4: 3.14). Conclusions: FIB-3 index offers similar diagnostic accuracy to FIB-4 index while demonstrating more consistent performance across age groups. These findings provide evidence that FIB-3 index may be a useful alternative, particularly in older populations where FIB-4 index interpretation may be confounded by age. Full article

Digital sexual harassment (DSH) perpetration among youth is a concerning issue that requires further research attention. This study examined the prevalence of DSH perpetration according to gender, age, sexual orientation, and relationship status, and explored risk factors (hostile sexism, benevolent sexism, and moral disengagement) and protective factors (online ethical values). A total of 1098 Spanish adolescents and young adults aged 13–23 years (Mage = 16.07, SDage = 2.38) completed a self-report survey. Descriptive, correlational, and binomial regression analyses were conducted. Results showed that 13.4% of participants engaged in DSH in the past 12 months. Male participants reported more than twice the rates observed among female participants (21.1% vs. 7.9%), and adolescents reported higher prevalence than young adults, whereas no differences emerged for sexual orientation or relationship status. Regression analyses indicated that benevolent sexism was a consistent predictor, while gender moderated the effects of hostile sexism and moral disengagement. Hostile sexism predicted perpetration only among female participants and predicted moral disengagement only among male participants. Importantly, online ethical values emerged as a novel protective factor, substantially reducing the likelihood of perpetration and buffering, though not eliminating, the risks associated with high moral disengagement. These findings provide evidence for prevention strategies and underscore the role of ethical values in addressing gendered forms of online violence. Full article
