Objective: To analyze the status of continuous ambulatory peritoneal dialysis (CAPD) in 12 centers in Turkey.
Design: Retrospective study of CAPD technique and patient outcome.
Setting: University hospital renal units.
Patients: 334 patients [205 males (61%),129 (39%) females; mean age 42.2 +/- 13.8 years; mean follow-up time 23.5 +/- 18.3 months] beginning CAPD between March 1992 and December 1999, and having a minimum follow-up of 3 months.
Outcome Measure: Patient survival, technique survival, and duration of hospitalization.
Results: Mean weekly Kt/V urea was 1.9 +/- 0.8, weekly creatinine clearance was 62.9 +/- 8.5 L/1.73 m2, and mean serum albumin level was 3.7 +/- 0.6 g/dL. 93 patients (28%) were withdrawn from peritoneal dialysis due to death (12.6%), transplantation (3.9%), transfer to hemodialysis (8.7%), patient failure to adapt (1.5%), and other reasons (1.2%). The major causes of death were cardiovascular disease (60%), infection (19%), malignancy (2%), and others (19%). Cox proportional hazard model analysis indicated age, serum albumin levels, comorbidity, and functional status affected survival and hospitalization (p < 0.05), whereas gender and Kt/V did not (p > 0.05). Estimation of patient survival by Kaplan-Meier analysis showed 94.2%, 88.6%, 84.5%, and 68.9% at 1, 2, 3, and 5 years respectively. Technique survival estimate by Kaplan-Meier analysis was 96.6%, 91.1%, 90.4%, and 77.4% at 1, 2, 3, and 5 years respectively.
Conclusion: Peritoneal dialysis is an acceptable method of renal replacement therapy in Turkey. There is controversy regarding the usefulness of Kt/V in predicting mortality and morbidity.

Objective: Cognitive impairment (CI) is highly prevalent in subarachnoid hemorrhage (SAH) patients. The phosphatidylinositol 3-kinase (PI3K)/AKT pathway plays a critical role in neuronal survival in a variety of central nervous system injuries. This study aimed to determine whether electroacupuncture (EA) at and LI20 ameliorates SAH-CI in a rat model and to examine whether it modulates the PI3K/AKT pathway by administering a PI3K inhibitor (LY294002) versus dimethyl sulfoxide (DMSO) vehicle.

Background: Bowel trauma, encompassing injuries to the small and large intestine, represents a significant medical challenge due to its potential for morbidity and mortality. Management of bowel injuries remains surgical, but multiple factors influence the outcome in these patients. This study provides an in-depth analysis of the high-risk features of hollow visceral trauma in the ICU setting and the corresponding mortality rates, shedding light on the critical factors that influence outcomes in these cases.

Background: Endocrine hypertension is believed to be underestimated worldwide especially in the developing countries. There is a scarcity of publications on endocrine hypertension in sub-Saharan Africa. The aim of this study was to reflect the profile of patients with endocrine hypertension of adrenal/paraganglioma origin at Chris Hani Baragwanath Academic Hospital (CHBAH).

Background: COVID-19 was first identified in Wuhan, China, in December 2019, where it spread over a wide geographic area until it reached the status of a pandemic in 2020. We postulated that patients who were diagnosed with incidental COVID-19, and underwent surgery, did not have a worse outcome due to the COVID-19 virus compared to their counterparts who did not have the virus.
Methods: This retrospective study included surgical patients (COVID-19 incidentals and COVID-19 negatives) who were admitted to the surgical intensive care unit (SICU) at Tygerberg Academic Hospital between 1 May 2020 and 31 December 2021.

Background: This study aimed to assess the contribution of human error to adverse events over 10 years in a single surgical department in South Africa.
Methods: A retrospective database analysis was undertaken to identify all adverse events, which were further assessed to identify which were error-associated.
Results: A total of 14 237 adverse events occurred between December 2012 and January 2023, of which 7 504 (52.
