Abstract Radical cystectomy is a preferred treatment for muscle invasive bladder cancer. Despite known complications, rapid onset, severe hyperkalemia necessitating abortion of surgery has not been reported. In this case report, a patient with end stage renal disease (ESRD) undergoing attempted cystectomy developed severe intraoperative hyperkalemia and acidosis that led to abortion of surgery and transfer to the medical intensive care unit for emergent hemodialysis. The multifactorial etiology was related to respiratory acidosis, ESRD, patient positioning, clipping of ureters, and body habitus, as well as an idiopathic element. Knowledge of hyperkalemia etiologies can assist in diagnosis More >

Abstract Laubry-Pezzi syndrome (L-PS) is a rare congenital heart disease characterized by a ventricular septal defect (VSD) and aortic valve prolapse. These cardiac lesions predispose individuals to infective endocarditis (IE), a life-threatening complication, especially in resource-constrained settings. A 17-year-old male presented with a three-week history of fever and headache, and a one-week history of abdominal pain, vomiting, and diarrhea. On presentation, he appeared toxic, was febrile, tachypneic, tachycardic, and blood pressure of 120/30 mmHg, and heart sounds were S1, S2. Abdominal examination revealed generalized tenderness. A provisional diagnosis of typhoid sepsis with intestinal perforation was considered.… More >

Abstract Background: Post-operative atrial fibrillation (POAF) frequently occurs after cardiac surgery. Although adult congenital heart disease (ACHD) patients have higher rates of arrhythmia than the general population, there is scant literature on POAF in ACHD patients. Objectives: Identify key risk factors associated with post-operative atrial fibrillation and evaluate the short- and mid-term significance of developing POAF. Methods: A retrospective cohort study was conducted of ACHD patients from 2013–2021 at the University of Colorado Hospital and Children’s Hospital of Colorado. The institutional Society of Thoracic Surgeons (STS) surgical registry was used to identify patients ≥18-year-old with congenital heart… More >

Abstract Background: Failure to rescue has been an effective quality metric in congenital heart surgery. Conversely, morbidity and mortality depend greatly on non-modifiable individual factors and have a weak correlation with better-quality performance. We aim to measure the complications, mortality, and risk factors in pediatric patients undergoing congenital heart surgery in a high-complexity institution located in a middle-income country and compare it with other institutions that have conducted a similar study. Methods: A retrospective observational study was conducted in a high-complexity service provider institution, in Cali, Colombia. All pediatric patients undergoing any congenital heart surgery between… More >

Abstract Introduction: 5α-reductase inhibitors (5ARI) are commonly prescribed medications. There is ongoing controversy about the adverse events of these medications. The aim of this study is to characterize lawsuits in Canada involving medical complications of 5ARIs use.
Materials and methods: Legal cases were queried from CanLII. Cases were included if they involved a party taking a 5ARI who alleged an adverse event. Relevant full cases were retained, and pertinent characteristics were extracted with the help of a legal expert.
Results: Our deduplicated search yielded 67 unique legal documents from December 2013 to February 2019. Twelve of these documents met… More >

Abstract Introduction: To evaluate the clinical characteristics as well as the postoperative course of urolithiasis patients undergoing a ureteroscopy (URS) without stent placement.
Materials and methods: This was a prospective case cohort study utilizing data collected in the Registry for Stones of the Kidney and Ureter (ReSKU) from a single institution between October 2015 and December 2020. We identified all consecutive patients undergoing URS for stone disease and analyzed data encompassing demographics, medical history, intra and postoperative characteristics, including complications and postoperative symptoms. Univariate and multivariate logistic regression analyses were performed based on the presence or absence of… More >

Abstract Background: Research on fetal congenital heart defect (CHD) mostly focuses on etiology and mechanisms. However, studies on maternal complications or pathophysiology are limited. Our objective was to determine whether vascular dysfunction exists in pregnant women carrying a fetus with congenital heart defects. Methods: We conducted a case-control study. 27 cases of pregnant women carrying a fetus with major CHD admitted to our hospital for delivery between April 2021 and August 2022 were selected. Every case was matched with about 2 pregnant complication-free controls without fetal abnormalities. The proangiogenic and anti-angiogenic factors and pregnancy outcomes were… More > Graphic Abstract

Abstract Background: The increasing occurrence of diabetes mellitus (DM) noted worldwide has considerably elicited concern in the recent past. DM is associated with elevated vascular complications, morbidity, mortality, and poor quality of life. In this context, mesenchymal stem cells (MSCs) have shown significant therapeutic potentialities in managing and curing type 1 DM owing to their self-renewable, immunosuppressive, and differentiation capacities. We investigated the potential action of N, N′-diphenyl-1,4-phenylenediamine (DPPD), a well-known synthetic antioxidant to enhance the therapeutic ability of the adipose-derived stem cells (AD-MSCs) in alleviating kidney and liver complications in diabetic rats. Methods: Over the… More > Graphic Abstract

Abstract Background: Transcatheter closure of patent foramen ovale (PFO) has been widely accepted as a highly effective way to treat high-risk PFO-related diseases. However, traditional non-degradable occluders made of metal alloys will permanently exist in the body, resulting in thrombosis, valve damage, hemolysis, arrhythmia, or other complications. The biodegradable PFO occluder developed by Shanghai Mallow Medical Instrument Co., Ltd., China can be fully absorbed and degrade into nontoxic ingredients, reducing postoperative complications. Objectives: To study the safety and efficacy of biodegradable PFO occluders in treating PFO. Methods: This single-center clinical trial collected 30 patients treated with a More > Graphic Abstract

Abstract Introduction: To elucidate the association between operative duration (OD) and postoperative complications, which has been poorly studied in radical cystectomy. We hypothesize an increase in morbidity in radical cystectomy cases which have a longer OD.
Materials and methods: Data from the National Surgical Quality Improvement Program (NSQIP) between the years 2012 and 2018 were reviewed for radical cystectomy with ileal conduit urinary diversion or continent diversion. Total operative time was divided into deciles and stratified comparisons were made using univariable and multivariable analysis.
Results: A total of 11,128 patients were examined. OD by minutes was stratified into the… More >
