BACKGROUND Long-term low-dose aspirin (LDA) use is associated with an increased risk of peptic ulcer bleeding (PUB). Helicobacter pylori (H. pylori ) infection is a well-known risk factor for peptic ulcer disease (PUD). AIM To evaluate the prevalence of H. pylori infection in long-term LDA users, assess the impact of eradication on PUB risk, and explore its association with cardiovascular (CV) disease status and progression. METHODS A prospective observational study was conducted at Benha Teaching Hospital from January 2023 to January 2024. Four hundred adults (≥ 18 years) on daily LDA for at least one year were enrolled. All participants underwent a comprehensive evaluation, including assessment of CV comorbidities. H. pylori was diagnosed via a stool antigen test, urea breath test, and histopathology. Infected patients received levofloxacin-based triple therapy for 14 days. Eradication was assessed at six weeks, and participants were followed for six months to evaluate PUB incidence and CV outcomes, including disease progression. RESULTS The prevalence of H. pylori infection was 65.5% (262/400). H. pylori -positive patients exhibited significantly lower albumin levels (3.5 ± 0.4 g/dL vs 3.9 ± 0.6 g/dL, P < 0.001) and higher levels of urea (29.3 ± 6.4 mg/dL vs 23.5 ± 4.6 mg/dL, P < 0.001), sodium (137.8 ± 2.9 mmol/L vs 135.3 ± 3.5 mmol/L, P < 0.001), potassium (4.1 ± 0.9 mmol/L vs 3.8 ± 0.6 mmol/L, P = 0.014), and cholesterol (191.0 ± 29.7 mg/dL vs 177.0 ± 35.9 mg/dL, P = 0.004). PUB was significantly more prevalent in H. pylori -positive patients with gastric erosions (12.2% vs 0.0%, P < 0.001), peptic ulcers (23.7% vs 0.0%, P < 0.001), and gastric ulcers (10.7% vs 0.0%, P < 0.001). After eradication therapy, 51.9% (136/262) of patients tested negative for H. pylori , while 48.1% (126/262) remained positive. PUB was significantly more frequent in patients with persistent H. pylori infection (8.7% at 6 weeks, 11.9% at 6 months) compared to those with successful eradication (1.5% at 6 weeks, 3.7% at 6 months, P < 0.001), highlighting the importance of successful eradication in reducing PUB risk. Additionally, H. pylori -positive patients had a higher prevalence of ischemic heart disease (54.3% vs 33.3%, P < 0.001) and a higher burden of CV disease progression during follow-up (hazard ratio = 3.5, P < 0.001), suggesting a potential interaction between H. pylori infection and CV risk. CONCLUSION Successful screening and eradicating H. pylori in high-risk LDA users was associated with significantly reduced PUB risk and was linked to less CV disease progression in patients with persistent infection.

Cells in metabolically active tissues with high biosynthetic and secretory demands often use robust stress-responsive mechanisms to maintain homeostasis. Coordinating such stress response mechanisms requires intercellular communication and coordination. Such modalities of intercellular communication have been relatively understudied in the context of stress tolerance. Here, we use the Drosophila melanogaster third instar fat body to demonstrate that adipocytes communicate with each other through intercellular bridges called ring canals to buffer endoplasmic reticulum (ER) stress. The fat body supports the exponential growth from embryo to late larval stage over a short period of time through its energy storage and secretory functions, enduring a high basal level of stress in the process. We discovered that individual cells in the fat body are paired to one neighboring cell through ring canals. We further demonstrate that ring canals mediate rapid and highly specific intercellular cargo and organellar trafficking, and allow the transport of cytoplasmic, ER-bound, and Golgi vesicular proteins. Disrupting fat body ring canals resulted in higher levels of stress response markers, aberrant cell size, and increased cell sensitivity and lethality in response to various exogenous stressors. We also find that animals with disrupted fat body ring canals display an overall delay in larval development, likely due to reduced secretion of larval serum proteins from the fat body. In sum, our work reveals a novel feature of intercellular communication in adipose tissue that serves to buffer stress across cells, which is required for both homeostatic secretory function and maintaining tissue viability under exogenous stress.

Incident endometriosis diagnosis and AMH: how surgical staging and typology relate to serum AMH levels.

Introduction: Temporomandibular Disorders (TMDs) are musculoskeletal conditions often linked to psychological stress. Cortisol, a key stress biomarker, may play a role in the pathophysiology of TMD. The present study compares salivary cortisol levels in young adults with TMD, with and without depression, and in healthy controls to explore the psychological and physiological interplay in these conditions. Identifying distinct cortisol patterns across these groups could aid in understanding the role of stress-related endocrine function in TMD. Aim: To test salivary cortisol levels in young adults diagnosed with TMD, both with and without depression, and to compare these results with an age-matched control group without TMD and depression. Materials and Methods: The present cross-sectional observational study was conducted at Vishnu Dental College, Bhimavaram, between January and May 2024. The present study included individuals aged 18-28 years of both genders who experienced pain in the Temporomandibular Joint (TMJ) region for a minimum of three months, in accordance with the Research Diagnostic Criteria for TMD (RDC/TMD). A total of 45 patients were divided into three groups: TMD with depression (n=15), TMD without depression (n=15), and a control group (n=15). Patients were evaluated for TMD based on the RDC/ TMD criteria. Psychological status was assessed using the RDC/TMD Axis 2 self-report for all participants, including those with TMD and the control group without TMD. Post awakening salivary samples were collected between 7 and 8 a.m., and salivary cortisol levels were measured using an Enzyme-Linked Immunosorbent Assay (ELISA) kit. Data analysis was performed using a paired t-test, and Pearson correlation was used to examine the relationship between morning and evening cortisol levels. An Analysis of Variance (ANOVA) test was conducted to compare cortisol levels across groups, with a p-value <0.001 considered significant. Results: A strong, significant correlation was found between morning and evening salivary cortisol levels in all groups (TMD with depression: r=0.99; TMD without depression: r=0.989; controls: r=0.725; p<0.001). Morning cortisol was highest in TMD patients with depression (55.7 ng/mL), followed by those without depression (19.63 ng/mL) and controls (12.66 ng/mL). Evening levels followed a similar pattern. Females showed significantly higher cortisol levels than males, especially in the TMD without depression and control groups (p<0.001). In TMD with depression, females had higher levels, though this was not statistically significant. Conclusion: Assessing salivary cortisol levels may provide insight into psychological factors that contribute to the development of TMD. Salivary cortisol could serve as a valuable indicator in detecting psychological elements potentially linked to TMDs.

Burnout levels among nursing home care workers and its associations with workplace and individual factors: Results from a multicenter cross-sectional study.

Background: Colonoscopy is the gold standard for ulcerative colitis diagnosis. However, colonoscopy is invasive & often requires deep sedation & extensive preparation. The current study compared fecal calgranulin C versus fecal calprotectin in ulcerative colitis as a predictor of activity, compared to the invasive procedure of colonoscopy. Patient and Methods: 50 patients diagnosed with UC were involved in this study. They enrolled from the Gastroenterology Department. Patients with gastric malignancy, necrotizing enterocolitis, IBS & colonic cancer, or pregnant females were excluded. Results: Patients in the active group had significant anemia, higher WBCs, higher absolute neutrophilic count, lower lymphocytes %, lower serum albumin levels, higher CRP levels & higher ESR levels compared to those in the remission state. Patients in the active group had higher fecal calprotectin levels (630.18 μg/mg) & fecal Calgranulin C (689.32 μg/mg) levels in comparison to patients in the remission state (76.64 & 82.68 μg/mg), respectively. While there were statistically significant negative correlations between fecal calprotectin level & hemoglobin, lymphocytes %, monocytes % & serum albumin. There were statistically significant positive correlations between fecal Calgranulin C level & WBCs, absolute neutrophilic count, neutrophils %, NLR, CRP & ESR1. There was a highly statistically significant positive correlation between fecal Calgranulin C level & fecal calprotectin levels. Conclusion: Fecal Calgranulin C is more specific compared to other inflammatory markers in the prediction of Ulcerative colitis activity. Therefore, it is recommended to include it in the follow-up of UC patients.

The beneficial effects of physical activity (PA) on cardiovascular disease and its risk factors have been well established. However, evidence linking PA to chronic kidney disease (CKD) in patients with diabetes is limited. This study aimed to examine the association between PA, including leisure-time PA (LTPA) and daily life PA (DLPA), and CKD cross-sectionally. A total of 4,922 patients with type 2 diabetes were classified into quartiles of LTPA and three categories of DLPA (sedentary, light, and moderate/vigorous). CKD was defined as a decreased estimated glomerular filtration rate (eGFR) based on cystatin C (< 60mL/min/1.73 m2) and/or albuminuria (urinary albumin-to-creatinine ratio ≥ 30mg/g). Odds ratios for the presence of CKD were computed using logistic regression analyses. Higher LTPA levels were significantly associated with a lower likelihood of developing CKD (P for trend = 0.001). Higher DLPA was also associated with a lower prevalence of CKD (P for trend < 0.001). Similar associations were observed for decreased eGFR and albuminuria. The combination of higher LTPA and DLPA levels further decreased the likelihood of CKD, with a significant interaction between the two. Higher LTPA and DLPA levels were independently associated with a lower prevalence of CKD in patients with type 2 diabetes.

The evidence remains contradictory regarding the optimal glycaemic targets needed to address the long-term effects of hyperglycaemia in people with diabetes mellitus (T2DM). We examined the association between HbA1c levels and the risk of individual microvascular complications among people with T2DM. We used the Clinical Practice Research Datalink (CPRD) GOLD database for a prospective cohort study, following patients ≥18years old from diagnosis of T2DM between January 2007 and December 2017. Neuropathy included foot ulcers, peripheral arterial disease, gangrene, and amputation. Nephropathy was classified by chronic kidney disease stages, and retinopathy included blindness and macular oedema. The risk of each complication in five HbA1c intervals [1.0%] intervals compared to 48.0-57.9mmol/mol (6.5-7.5%) was assessed using a multivariate time-varying Cox regression adjusted by various patients' characteristics. Subgroup analyses were performed according to age, hypertension, and the use of antihypertensive medications. Our study included 172,869 patients (mean age 62.6years and, 54.6% women). The risks were the highest in HbA1c levels >81.0mmol/mol (>9.6%) (HR 1.27, 95%CI 1.17-1.39 for nephropathy; 1.55, 1.27-1.47 for neuropathy; 1.66, 1.41-1.96 for retinopathy). The lowest risks observed in levels 48.0-57.9mmol/mol (6.5-7.5%) for nephropathy and in levels <48.0mmol/mol (<6.5%) for neuropathy (0.98, 0.88-1.09) and for retinopathy (0.89, 0.79-0.99). In the subgroup analysis, higher HbA1c levels were associated with an increased risk of nephropathy, particularly in individuals over 60, those with hypertension, and those using antihypertensive medications. For neuropathy, being over 60 was associated with an increased risk across all HbA1c levels. In retinopathy, hypertension and the use of antihypertensive medications were associated with lower risk across all HbA1c levels, while individuals under 60 were associated with higher risks at elevated HbA1c levels compared to those over 60. The risk of retinopathy and neuropathy was lowest in individuals with HbA1c levels within the non-diabetic range <48.0mmol/mol (<6.5%) and increased progressively with higher HbA1c levels. In contrast, the lowest risk of nephropathy was observed in individuals with HbA1c levels between 48.0 and 57.9mmol/mol (6.5-7.5%). These findings underscore the importance of a personalized approach to diabetes management that considers multiple risk factors and incorporates novel therapeutic strategies beyond glucose control.

The association of iodine nutritional status with thyroid function in iodine-replete countries is controversial and more sensitive biomarkers than urinary iodine concentration is required. To evaluate the use of scalp hair and serum iodine concentration as measure of iodine status through their association with thyroid indices. A nationwide survey was conducted between 2016 and 2023. Iodine concentration in serum (SIC), hair (HIC), urine (UIC) and estimated 24-hour urinary iodine excretion (eUIE), dietary iodine intake (DII) as well as serum TSH, FT4, and FT3 concentrations, thyroid antibody (ThAb) was measured in Japanese adults. The median UIC in 2771 adults was 295.0 μg/L and within the WHO's adequacy range of iodine intake. The high iodine intake assessed by UIC, eUIE and SIC was associated with higher TSH and lower thyroid hormone levels. Urinary iodine concentration, eUIE and DII were higher in the group with a high TSH level. The subjects with positive ThAbs had significantly higher SIC, DII, TSH and slightly lower FT4 levels. The median HIC correlated positively but weakly with SIC, eUIE and DII, while SIC correlated modestly with eUIE, UIC and weakly with DII. The 5th percentile of the SIC reference (49.9 μg/L) coincided with the threshold value of median UIC (<100 μg/L) for iodine deficiency by WHO. Higher iodine intake results in changes of TSH and thyroid hormones within their referenced range. Serum and hair iodine concentrations might be feasible indicators for a population's iodine intake and further research is needed to validate their availability.

In observational studies, blood pressure (BP) variability has been independently associated with adverse cardiovascular disease outcomes. The Dietary Approaches to Stop Hypertension (DASH) diet and sodium reduction lower BP and cardiovascular risk, but their effects on BP variability (BPV) are uncertain. This study assessed the effects of dietary patterns (DASH vs. Control) and sodium intake (higher vs. lower) on BPV, using both office and 24-h ambulatory BP measurements in the DASH and DASH-Sodium trials. In primary analyses, week-to-week office BPV and 24-h ambulatory BPV were quantified using variation independent of the mean (VIM). Between-group comparisons were performed using t-tests; interactive effects between dietary patterns and sodium intake were assessed using multivariate linear regression models. In pooled analyses of both trials, there was no difference in week-to-week systolic BPV (difference in systolic VIM: 0.49, 95% CI -0.05-1.03) or 24-h systolic BPV (difference in systolic VIM: 0.37, 95% CI -0.13-0.87) between the DASH and Control diet groups. In the DASH-Sodium trial, VIM at higher and lower sodium levels did not differ (e.g. difference in VIM for week-to-week systolic BP: 0.31, 95% CI -0.10-0.72). No significant combined or interactive effects of diet and sodium level on BPV were observed. While the DASH diet and reduced sodium intake lower absolute BP levels, these dietary interventions do not significantly affect BPV. These findings suggest that the BP-related benefits of the DASH diet and sodium reduction likely result from reducing absolute BP rather than reducing BPV.

Inflammation mediates the association of heavy metal exposures with kidney function: Evidence from a longitudinal study.

The widespread integration of digital technologies into adolescents' daily lives has raised concerns about potential behavioral correlates, including aggression. Although prior research suggests a relationship between technology use and aggressive behavior, results are mixed and often context-dependent. This study aimed to examine the association between information technology use and aggression among Turkish adolescents. A descriptive cross-sectional study was conducted with 841 adolescents aged 11-14 years recruited from three public secondary schools in southeastern Turkey between February 3, 2025, and February 14, 2025. Data were collected using a sociodemographic questionnaire, the Information Technologies Usage Scale, and the Aggression Scale. Pearson correlation analyses and hierarchical multiple linear regression models were performed to examine associations between technology use and aggression, both before and after controlling for demographic and familial variables. Technology use was positively associated with aggression (r = 0.296, p < 0.001). In regression analyses, information technology use remained a significant predictor of aggression after adjustment for covariates (β = 0.235, p < 0.001), explaining a small proportion of variance. Among technology sub-dimensions, digital game playing and use of technological devices and applications were significantly associated with higher aggression scores, whereas virtual life preference was not. Longer daily technology use was also associated with higher aggression levels. Higher levels of technology engagement, particularly digital gaming and device use, were associated with increased aggression scores among adolescents, although the magnitude of these associations was small. Given the cross-sectional design, causal inferences cannot be drawn. The results highlight the importance of considering both the type and duration of technology use in adolescent behavioral research and underscore the need for longitudinal studies to clarify temporal relationships and underlying mechanisms.
