Background: Inflammation plays a central role in the formation of peptic ulcers, yet the contribution of cellular immunity remains poorly defined. This study aimed to clarify the contribution of cellular immunity to acute gastric mucosal injury.

Methods: BALB/c mice received 80% ethanol via oral gavage to induce acute gastric injury. Stomachs were examined macroscopically and histologically, and gastric tissues were analyzed by qPCR, ELISA, and flow cytometry for cytokine expression, immune cell infiltration, and apoptosis.

Results: Administration of ethanol exacerbated acute gastric injury in mice, as evidenced by extensive macroscopic lesions and severe disruption of mucosal architecture. This damage was accompanied by marked infiltration of CD11c⁺ dendritic cells, together with an increased frequency of CD86-expressing and IL-12-producing dendritic cells. In addition, there was greater accumulation of both CD4⁺ and CD8⁺ T lymphocytes, including elevated numbers of CD4⁺ and CD8⁺ cells producing IFN-γ and IL-17, as well as CD8⁺CD107a⁺ cytotoxic cells. Alongside these cellular alterations, ethanol exposure was accompanied by elevated levels of pro-inflammatory cytokines (IL-1β, TNF-α, IL-17, and IFN-γ) in gastric tissue. In parallel, ethanol exposure also promoted epithelial cell apoptosis, further contributing to mucosal deterioration.

Conclusions: Our findings reveal for the first time that both CD4⁺ and CD8⁺ T cells participate in sterile ethanol-induced acute gastric injury, emphasizing cellular immunity as an important yet insufficiently studied contributor to mucosal damage and highlighting the necessity for further mechanistic and translational research.

Background: Silicosis is a lung disease caused by inhalation of crystalline silica dust, leading to lung fibrosis, respiratory symptoms, and impaired lung function. This study aimed to determine the prevalence of silicosis, asthma, and chronic obstructive pulmonary disease (COPD), and to identify factors associated with abnormal pulmonary function among residents living in dust-exposed areas in Thailand. Methods: A cross-sectional study was conducted from March 2024 to July 2024 among adults aged 18 years or older in Saraburi, Thailand. Data collected included demographics, comorbidities, respiratory symptoms, risk of silicosis, chest radiographs, and spirometry (forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), and bronchodilator responsiveness (BDR)). Silicosis was confirmed based on a history of significant silica exposure and characteristic chest radiographic findings. Results: Among 290 participants (55.9% female, mean age 47.6 ± 16.4 years), the prevalence of silicosis, asthma, and COPD was 0.3%, 4.5%, and 10.3%, respectively. Abnormal chest radiographs were observed in 8.3%, and abnormal lung function in 34.1%, including restrictive lung patterns (16.6%), airway obstruction (9.0%), mixed defects (2.8%), and small-airway disease (5.9%). BDR was observed in 4.8%. Logistic regression identified increasing age as a significant predictor of abnormal lung function. Conclusions: Silicosis prevalence was lower than that of asthma and COPD, but abnormal pulmonary function-especially restrictive defects-was common. Notably, the prevalence of asthma and COPD was higher than previously reported community-based diagnosis rates, suggesting potential underdiagnosis. Older age was associated with a higher likelihood abnormal lung function. These findings highlight the need for targeted surveillance, preventive measures, and public health interventions to mitigate the respiratory impacts of dust exposure in community settings.

Background: Hypertension and psychological distress often coexist, though evidence from Eastern Europe is still limited. Stress, anxiety, and self-efficacy influence blood pressure control and treatment adherence. Their effect on hypertension prevention and treatment has not been systematically evaluated in Romania. Aim: This study evaluated the associations between stress, anxiety, and self-efficacy in Romanian adults with and without hypertension to identify modifiable psychological factors relevant for integrated cardiovascular management. Methods: A retrospective case-control study was conducted among 215 adults, including individuals with hypertension and normotensive controls. Participants completed validated questionnaires assessing stress vulnerability, perceived stress, state and trait anxiety, self-efficacy, and Type A behavior, together with demographic and occupational data. Results: Hypertensive participants reported higher stress vulnerability, perceived stress, and anxiety, as well as lower self-efficacy, compared with controls. Type A behavior showed no association with hypertension. These differences remained consistent after accounting for demographic characteristics. Conclusions: Hypertension in Romanian adults is associated with a distinct psycho-emotional profile characterized by elevated stress and anxiety and reduced self-efficacy. Type A personality showed no association. The results emphasize the importance of recognizing and addressing modifiable psychological determinants in hypertension care. Integrating psychosocial assessment with personalized interventions, including mindfulness-based approaches, digital health support, and nurse-led telemonitoring, could improve treatment adherence, reduce emotional burden, and contribute to overall cardiovascular health. This region-specific evidence supports expanding hypertension management to include psychological care alongside standard medical approaches.

Background: Central precocious puberty (CPP) is diagnosed through a combination of clinical, auxological, and biochemical parameters, with pharmacological stimulation tests considered the diagnostic gold standard. In recent years, triptorelin, a long-acting Gonadotropin-Releasing Hormone (GnRH) analog, has been increasingly adopted in clinical practice due to limited availability of native GnRH.

Objective: To compare the clinical, auxological, and hormonal profiles of girls diagnosed with idiopathic CPP using either the classical GnRH stimulation test or the triptorelin test.

Methods: This retrospective study included 136 female patients diagnosed with CPP and followed for at least two years at a single pediatric endocrinology unit. Of these, 101 underwent a GnRH stimulation test, and 35 were assessed using the triptorelin test. Baseline and stimulated hormonal parameters, growth data, and IGF-1 levels were collected. A multivariate linear regression model was used to explore the influence of age, test type, and other covariates on the LH peak response.

Results: Anthropometric and baseline hormonal parameters were comparable between the two groups. The LH peak was significantly higher in the GnRH group (9.8 ± 3.1 IU/L at 60 min) than in the triptorelin group (6.8 ± 2.4 IU/L at 4 h). FSH levels were also significantly lower following triptorelin stimulation (p = 0.004), while the LH/FSH ratio did not differ significantly. Multivariate analysis confirmed that triptorelin was associated with a lower LH peak (β = -2.2, p = 0.008), particularly in younger patients, with a significant interaction between age and test type (β = 0.6, p = 0.022).

Conclusions: Both GnRH and triptorelin stimulation tests are valid tools for CPP diagnosis. However, the GnRH test appears to elicit a more robust LH response, especially in younger patients, whereas the triptorelin test is associated with delayed and lower LH peaks.

A traumatic elbow dislocation that remains unreduced for more than three weeks is considered a neglected elbow dislocation. We report a case of a patient with a neglected elbow dislocation combined with a terrible triad injury (elbow dislocation with fractures of the coronoid process and radial head). Initially, the patient was managed with three weeks of cast immobilization followed by physiotherapy. However, six months after the trauma, he presented to our clinic with severe heterotopic ossification, significant pain, and nearly complete elbow stiffness. An open surgical intervention was performed, involving excision of the heterotopic bone, reduction in the dislocation, and suturing of the anterior capsule to the coronoid process. Given the irreparable fracture of the radial head, radial head arthroplasty was also performed. At 18-month follow-up, the elbow was stable and pain-free, with flexion-extension of 80°, pronation of 85°, and supination of 80°. This case underscores the critical importance of early diagnosis and intervention to prevent long-term complications in neglected elbow dislocations.

Background: Gynecological infections, including bacterial vaginosis, vulvovaginal candidiasis, and recurrent urinary tract infections, represent a major clinical burden and are often complicated by biofilm formation and antimicrobial resistance. Novel non-antibiotic strategies are urgently needed. We previously demonstrated the antimicrobial activity of silver-bound titanium dioxide (TiAB) against multidrug-resistant bacteria isolated from dermatological infections. Objectives: We evaluated whether TiAB, at concentrations used in marketed medical devices, exerts antibacterial and antifungal effects against clinically relevant vaginal isolates by determining Minimum Inhibitory Concentration/ Minimum Bactericidal and Fungicidal Concentration (MIC, MBC/MFC), and time-kill kinetics. Methods: A total of 73 clinical isolates were collected from vaginal swabs, including Staphylococcus aureus (MSSA, MRSA), Escherichia coli (ESBL+ and non-ESBL), Klebsiella pneumoniae, Enterococcus spp., Streptococcus agalactiae, and Candida albicans. Minimum inhibitory concentrations (MICs) and minimum bactericidal/fungicidal concentrations (MBCs/MFCs) were determined by broth microdilution, and bactericidal activity was confirmed by time-kill assays. Results: TiAB exhibited potent activity against Gram-negative bacteria, with median MIC values of 1-2% (w/v) for E. coli and K. pneumoniae. Gram-positive isolates, including S. agalactiae and Enterococcus spp., showed higher MIC values (2-4%). Candida albicans displayed fungistatic inhibition at 4%. Time-kill assays confirmed rapid bactericidal effects for Gram-negative isolates within 8 h at 2× MIC, while Gram-positive bacteria required prolonged exposure. Conclusions: These findings extend previous evidence of TiAB's antimicrobial properties to gynecological pathogens, supporting its potential as a topical, non-antibiotic option for managing vaginal infections in an era of rising antimicrobial resistance. Further in vivo validation is warranted.

Background: Pediatric oncological diagnoses and treatments pose complex biopsychosocial challenges for both patients and their families. These experiences can significantly disrupt daily life, evoke intense emotional responses, and raise concerns about the future, often leading to long-term psychological implications. Objective: This study aimed to assess the emotional functioning of children undergoing cancer treatment and to explore the lasting psychological effects reported by young adult survivors of pediatric cancer. Methods: A mixed-methods approach was employed. In total, 52 minors and their caregivers were recruited from two pediatric oncology units in Italy (Turin and Bari), while 18 young adults diagnosed during childhood were recruited from clinical and community settings in Ancona and Bari. Standardized instruments were used to evaluate emotional symptoms and broader psychological functioning in the pediatric sample, while self-report measures assessed psychological well-being and quality of life in the young adult group. To complement these data, semi-structured interviews were conducted with the young adult survivors to investigate the long-term psychosocial and psychological impacts of pediatric cancer. Results: The quantitative results indicate generally low levels of psychological distress in both groups. However, the qualitative findings reveal the complexity of post-cancer identity, highlighting experiences of resilience, emotional ambivalence, and redefinition of self. Conclusions: These results underscore the importance of addressing the psychological well-being of pediatric oncology patients and young adult survivors beyond the medical treatment phase, with a focus on long-term psychosocial support and individualized care.

Background and Objectives: Necrotizing enterocolitis (NEC) represents a severe gastrointestinal emergency in preterm infants. The aim of this study was to identify risk factors and predictive parameters for NEC requiring surgery and to evaluate associated short-term outcomes. Materials and Methods: We conducted a retrospective study in preterm neonates diagnosed with NEC admitted to a tertiary neonatal intensive care unit (NICU) between January 2015 and May 2025. Demographic data, perinatal events, risk factors, clinical signs, imaging findings, and outcomes were analyzed, with a particular focus on surgically managed cases. Descriptive and inferential statistical methods were applied. Results: Forty-four infants met the inclusion criterion. The mean gestational age (GA) was 29.34 ± 4.3 weeks, and the mean birth weight was 1100 ± 563 g. According to Bell's severity index, 45.5% had Bell Stage I, 36.4% Stage II, and 18.2% Stage III. Eleven patients (25%) required surgery. All surgical patients had abdominal distension, and 63.6% had bilious gastric residue. Abdominal X-ray showed pneumoperitoneum in 72.7% and pneumatosis intestinalis in 27.3% of cases. Laboratory abnormalities, including thrombocytopenia, elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH), and hyponatremia (45.5%; 133 ± 6.95 mmol/L), were frequently associated with surgical NEC. A lower GA and birth weight correlated with a higher Bell stage (p = 0.0085 and p = 0.0291). Overall mortality was 29.5% (13/44); surgical mortality was 9.1% (1/11). Conclusions: In this single-center lot, low gestational age and birth weight, abdominal distension with bilious residuals, systemic inflammation, and hyponatremia were frequent among infants who required surgery. Selected infants may benefit from early surgery even without perforation, but inferences are limited by this study's sample size and retrospective design. Prospective multi-center studies are needed to validate predictors and refine surgical timing.

Background: Coronary artery bypass grafting (CABG) remains a standard revascularization strategy for patients with advanced coronary artery disease (CAD). However, a considerable proportion of patients experience recurrent ischemia requiring repeat revascularization. Residual platelet reactivity (RPR) and dyslipidemia are recognized as key factors contributing to graft failure and disease progression.

Methods: This observational study was conducted at a tertiary cardiology center in Kazakhstan. A total of 195 post-CABG patients who underwent repeat coronary angiography between 2023 and 2024 recruitment period for recurrent ischemic symptoms within 6-36 months after surgery were included. Clinical characteristics, comorbidities, lipid profiles, and antiplatelet response were analyzed. RPR was measured using the VerifyNow P2Y12 assay when available. Dyslipidemia was defined according to the 2019 and 2021 European guidelines.

Results: Elevated RPR was identified in 45% of patients (n = 90) despite dual antiplatelet therapy (p < 0.01). Poor lipid control was frequent among those who underwent repeat percutaneous coronary intervention (PCI), particularly elevated levels of low-density lipoprotein cholesterol (LDL-C) and total cholesterol (p < 0.05). Both elevated RPR and dyslipidemia were independently associated with native coronary disease progression and graft failure (RPR: OR = 2.8; 95% CI 1.4-5.6; p = 0.003; dyslipidemia: OR = 2.2; 95% CI 1.1-4.3; p = 0.02). The use of ezetimibe was independently associated with a significantly lower risk of repeat stenting (OR = 0.12; 95% CI 0.02-0.75; p = 0.023). Smokers were younger, had lower blood pressure, and less frequently presented with diabetes or chronic kidney disease, demonstrating a pattern consistent with the "smoker's paradox."

Conclusions: Residual platelet reactivity and dyslipidemia are common and clinically relevant predictors of repeat revascularization after CABG. Optimization of antiplatelet and lipid-lowering therapy should be prioritized in secondary prevention for this high-risk population. These findings are particularly important in Kazakhstan, where post-CABG management strategies warrant further improvement.
