Objective: Subarachnoid hemorrhage (SAH) is still considered a life-threatening medical condition with a high mortality rate, particularly in developing countries. Thus, the present study aimed to investigate the angiographic findings of non-traumatic or spontaneous SAH.

Methods: This retrospective cohort study included 642 health records of patients with non-traumatic SAH over a 10-year period, from 2010 to 2020. The required data, including demographic information, aneurysm type, size, location, disease severity classification, and secondary complications, were extracted.

Results: The study included 642 patients, with 262 (40.8%) being male. The mean age of the participants was 54.72±13.51 years. The most prevalent type of aneurysm was saccular (89.1%), while serpentine (0.2%) and dissecting saccular (0.2%) aneurysms had the least prevalence. The most frequently involved arteries were the anterior communicating artery (ACoA; 38%), internal carotid artery (ICA; 27.6%), and middle cerebral artery (MCA; 13.4%). There was a significant correlation between sex and aneurysms occurring at ACoA and ICA (< 0.0001), and ACoA - A1 (0.02). Patient age and sex were also significantly correlated with one another (<0.0001). There was no statistically significant correlation between sex, aneurysm size, Glasgow coma scale (GCS), and modified Rankin scale (MRS).

Conclusion: Based on our findings, the presence of aneurysms at ACoA, ACoA - A1, and ICA should be thoroughly ruled out in patients with severe headaches of sudden onset, particularly male patients of younger ages.

Background: The endoplasmic reticulum stress (ER stress) has been involved in various musculoskeletal disorders including non-traumatic osteonecrosis of femoral head (NT-ONFH).

Objective: The current study aimed to investigate the association of glucose-regulated protein 78 (GRP78) as well as CCAAT/enhancer-binding protein homologous protein (CHOP) expressions in serum and femoral head (FH) tissues with NT-ONFH's severity.

Methods: We enrolled NT-ONFH patients (n = 150) alongside healthy controls (HCs, n = 150).

Objectives: To compare the diagnostic accuracy of ULDCT to CXR for detecting non-traumatic pulmonary diseases at the emergency department (ED) and to study diagnostic confidence levels.

Methods: Secondary analysis of the prospective OPTIMACT trial (2418 ED participants randomly allocated to ULDCT or CXR). Diagnoses at imaging at the ED were compared to the reference diagnosis on day 28.

Patients' views on stroke prevention for atrial fibrillation after an intracerebral haemorrhage: a qualitative study.

Eur J Cardiovasc Nurs

January 2025

Liverpool Centre for Cardiovascular Science, University of Liverpool, Liverpool John Moores University, and Liverpool Heart and Chest Hospital, Liverpool, UK.

Aim: (i) To explore the attitudes of patients with atrial fibrillation (AF) towards oral anti-coagulation (OAC) for stroke prevention post-intracerebral haemorrhage (ICH) and (ii) to explore factors that influence patients' decision-making process for stroke prevention.

Methods And Results: Patients with documented diagnosis of AF and history of a non-traumatic ICH, who were eligible for long-term OAC were recruited from eight hospitals in England, using purposive sampling. Data were collected using semi-structured interviews and analysed using Framework analysis.

Introduction: The purpose of this study was to investigate the morphology and distribution characteristics of fat globules in osteomyelitis on magnetic resonance imaging (MRI).

Materials And Methods: Patients with pathologically-confirmed osteomyelitis and MRI scans were retrospectively enrolled, and fat globules on the MRI images were analyzed.

Results: Among 103 patients with non-traumatic osteomyelitis, 75 were fat globule negative and 28 were positive.

Purpose: To compare the erectile and urinary functions of ventral and dorsal onlay buccal mucosal graft (BMG) urethroplasty in the management of proximal bulbar urethral strictures (PBUS) in sexually active men.

Patients And Methods: We retrospectively included patients with primary non-traumatic PBUS who were treated with (BMG) urethroplasty at our department between March 2019 and March 2023 either ventral or dorsal approaches. Patients were assessed at 3- and 12-months postoperatively for urinary and erectile functions.
