Objective: Risk factors for hemorrhage due to gastric and/or duodenal ulcer in patients diagnosed by upper gastrointestinal (GI) endoscopy were investigated in the present study.
Methods: Medical records of 350 patients (226 males, 124 females) diagnosed as duodenal or gastric ulcers by GI endoscopy in the gastroenterology clinic were scanned retrospectively. Upper GI hemorrhage was detected in 92 patients by upper endoscopic examination. The medical history of non-steroidal anti-inflammatory drugs (NSAIDs) or acetylsalicylic acid (ASA) usage and the presence of coronary artery disease (CAD) were investigated in all patients with or without hemorrhage. Results were evaluated by Chi-square test and logistic regression analysis.
Results: The mean age of the patients was 50.4 ± 15.7 years (range: 25 to 82 years). Hemorrhage due to gastric or duodenal ulcer was identified in 92 patients (26%). Mean age was 64.6 ± 11.4 years in patients with hemorrhage and 45.7 ± 13.9 years in patients without hemorrhage. ASA usage was more common than NSAID in patients with ulcer hemorrhage (NSAID usage n=35 (40%); ASA usage n=51 (60%); p=0.035). Hemorrhage was reported in 20% of the females and in 28% of the males who have ulcer (p=0.055). Risk factors for hemorrhage were CAD (OR:24.75, 95% CI=1.6-96.7, p=0.001), ASA usage (OR:9.76, 95% CI=2.1-37.5, p=0.021), NSAID usage (OR: 4.72, 95%CI=1.1-16.5, p=0.032), age (OR: 11.59, 95% CI= 2.7-12.1, p=0.001), and male gender (OR: 2.56, 95% CI= 0.8, 9.6, p=0.052).
Conclusion: Advanced age, atherosclerosis, male gender and NSAID administration (particularly aspirin) are the major risk factors of upper GI hemorrhage in patients with gastric and/or duodenal ulcer.

Risk assessment is an important component of judicial decision-making in many areas of the law. In Australia, those convicted of terrorist offences may be the subject of continued detention in prison or extended supervision in the community if there is an "unacceptable risk" of them committing future terrorism offences. Forensic psychologists and psychiatrists may provide evidence of risk through identifying and measuring risk factors with the aid of tools that use scales based on statistical or actuarial risk prediction.

Background: The increasing awareness of the emotional consequences of emergency cesarean deliveries (C-sections) highlights their substantial role in fostering postpartum post-traumatic stress disorder (PTSD). This systematic review and meta-analysis aim to evaluate the prevalence and determinants of PTSD following emergency C-sections, as well as the implications of these events on maternal mental health and welfare.
Methods: Undertaking extensive searches of Scopus, PubMed, PsycINFO, and Google Scholar, we have incorporated studies published from 2013 onwards that examined the occurrence of PTSD following emergency C-sections.

Background: In USA, total shoulder arthroplasty (TSA) ranks amongst the top five surgeries that require hospitalization. As a result, the healthcare system in USA could face a considerable financial strain due to the emergence of subsequent pulmonary problems. This study aimed to conduct a thorough examination of the prevalence, influential factors and medical importance of pulmonary complications, with emphasis on pneumonia, respiratory failure and pulmonary embolism (PE) following total shoulder arthroplasty (TSA) procedures in USA.

Background: Umbilical outpouchings (UOs) in pigs are a multifactorial disease and little is known about effective prevention strategies and risk factors for UO development. UOs are common in Danish pigs and legislation complicates and increases the cost of keeping and raising pigs with UO. Recommendations for preventive measures exist but the scientific evidence behind the recommendations is often lacking.

Background: Pancreatic cancer is characterized by a complex tumor microenvironment that hinders effective immunotherapy. Identifying key factors that regulate the immunosuppressive landscape is crucial for improving treatment strategies.
Methods: We constructed a prognostic and risk assessment model for pancreatic cancer using 101 machine learning algorithms, identifying OSBPL3 as a key gene associated with disease progression and prognosis.
