This study developed and evaluated a convolutional neural network model trained on non-contrast CT images that achieved high accuracy (94.6%) and excellent discriminative performance in differentiating distal ureteral stones, vascular calcifications, and normal cases to assist radiologists in clinical decision-making.
This cross-sectional study of 800 HPV-positive women in Tehran found that endometriosis is significantly associated with a higher prevalence of high-risk HPV infection and abnormal colposcopic findings, suggesting a need for individualized cervical surveillance in this population.
This retrospective survival analysis of Ghanaian adults reveals that severe self-reported healthcare deprivation is most strongly and independently associated with high lived poverty, lack of electricity access, and difficulty accessing healthcare services, suggesting that addressing material living conditions and physical infrastructure is crucial for improving health equity alongside conventional health system interventions.
This study demonstrates that subjective sleep problems are the primary pathway linking lower perceived social support to increased psychological symptom burden, while longer and increasing sleep durations are associated with higher perceived stress in adults.
This retrospective cohort study of 110 adult ICU patients in Syria identifies severe neurological impairment (GCS ≤8), sepsis, mechanical ventilation, male sex, and older age as significant independent predictors of the 36.4% mortality rate associated with altered consciousness, highlighting the critical need for early risk stratification and management in resource-limited settings.
This study demonstrates that relying solely on CT for target delineation in brain metastases near the skull leads to significant underestimation of tumor volume and inadequate dose coverage compared to MRI-based delineation, particularly in local and simultaneous integrated boost radiotherapy, thereby highlighting the necessity of integrating contrast-enhanced MRI into treatment planning to prevent local failure.
This study presents a novel patient-specific 3D printing method using SLA technology and a specialized elastomer to create high-fidelity, transparent aortic aneurysm models from CT scans, thereby enhancing surgical training, preoperative planning, and clinical trial outcomes.
This study developed and validated the Saudi Healthy Meal Index (SHMI), a context-specific nutrient profiling tool designed to assess and rank the nutritional quality of traditional Saudi meals to support future research and public health policy.
In a randomized controlled trial involving patients undergoing laparoscopic or robot-assisted partial nephrectomy, the retro superior costotransverse ligament space block (RSSB) did not demonstrate superior postoperative analgesia or reduced opioid consumption compared to the erector spinae plane block (ESPB), although exploratory data suggested RSSB may offer better intraoperative hemodynamic stability and reduced remifentanil requirements.
This study demonstrates that pregnancy significantly alters hematological and proteomic profiles, leading to misclassification in standard thalassemia screening, but a pregnancy-adapted LC-MS/MS strategy combined with machine learning effectively improves carrier detection accuracy by accounting for gestation-specific changes.
