Background: The incidence of hypoalbuminemia in surgical patients varies in different studies with age, tumor stage, time interval to the first referral to a doctor, symptoms of disease and nutritional habits of the population. The main objective of this study was to evaluate the incidence of hypoalbuminemia in colorectal cancer patients undergoing scheduled surgery in an academic hospital in Romania and the impact of hypoalbuminemia on perioperative outcome. The secondary objective was to identify other possible risk factors for the post operative outcome.
Material And Methods: 252 patients undergoing scheduled colorectal surgery with anastomosis have been enrolled in the study. Incidence of hypoalbuminemia (serum albumin 3.5 g dL), fistulas and other postoperative complications (e.g.infections) has been evaluated. LOS and 30-days mortality have also been evaluated comparatively in patients with normal and low serum albumin.
Results: 28.9% of our patients were hypoalbuminemic. The incidence of fistulas was 5.5 % in the study group and 2.3% and 13.3% in patients with normal serum albumin and hypoalbuminemic patients, respectively (p=0.001). Multivariate analysis showed that the OR was 6.65 [95% CI:2.01-21.96] inpatients with moderate hypoalbuminemia and 24.75 [95% CI:6.75-90.67] in patients with severe hypoalbuminemia.Association between alcohol consumption and smoking increased risk ratio to 1.96 [95% CI: 0.51-7.46].
Conclusion: The high incidence of hypoalbuminemia in our patients justifies preoperative nutritional interventions and specific surgical protocols in emergency cases. Further studies are needed to exactly quantify the impact of smoking and alcohol consumption on postoperative outcome.

Department of Urology, Peking University Third Hospital, Beijing, China.
Background: Lymphatic leakage is a common complication after radical cystectomy and pelvic lymph node dissection (PLND) for muscle-invasive bladder cancer (MIBC).This study aimed to investigate the risk factors contributing to postoperative lymphatic leakage in patients with MIBC.
Materials And Methods: A total of 534 patients undergoing radical cystectomy and PLND were enrolled in the retrospective study at Peking University Third Hospital from January 2010 to July 2023.
Blood circulating LncRNAs: SNHG5 and ZFAS1 as biomarkers reflecting cachexia incidence in chronic heart failure patients.

Background: Systemic inflammation plays a crucial role in the development and progression of chronic heart failure (CHF) across all phenotypes. The continuous release of pro-inflammatory cytokines causes muscle atrophy and adipocyte breakdown, ultimately resulting in cachexia. Long non-coding RNAs (lncRNAs) are emerging as potential biomarkers associated with cachexia, as they indirectly regulate muscle and fat tissue metabolism.

Objectives: To assess the efficacy and safety of locally manufactured generic sofosbuvir-based direct-acting antivirals in the treatment of Hepatitis C virus (HCV) infected patients on maintenance hemodialysis.
Patients And Methods: We have conducted a retrospective multicenter study including patients on maintenance hemodialysis, treated with sofosbuvir-based regimens between 01/01/2017 and 09/30/2021. Patients were treated for 12 or 24 weeks, with sofosbuvir 400 mg + ledipasvir 90 mg 3 times/week, or sofosbuvir 3 times/week + daclatasvir 60 mg/d, or sofosbuvir + daclatasvir in coformulation, 3 times/week.
Use of Albumin-Adjusted Calcium Measurements in Clinical Practice.
JAMA Netw Open
January 2025
Division of Endocrinology and Metabolism, Department of Medicine, University of Calgary, Calgary, Alberta, Canada.
Importance: Using albumin-adjusted calcium is commonly recommended for for measuring calcium, but with little empirical evidence to support the practice.
Objective: To assess the correlation between total calcium measurements (with or without adjustment) vs the ionized calcium level as a reference standard.
Design, Setting, And Participants: This was a population-based cross-sectional study in the province of Alberta, Canada, including adults tested for serum total calcium and ionized calcium simultaneously between January 1, 2013, and October 31, 2019.
Prevalence and Risk Factors of Acute Kidney Injury After Colorectal Cancer Surgery.
J Gastrointest Cancer
January 2025
Surgical Oncology Department, Oncology Center Mansoura University (OCMU), Mansoura, Egypt.
Purpose: Acute kidney injury is a sentinel event affecting colorectal cancer patients either as a consequence of surgery or systemic chemotherapy. It is highly correlated with both short and long-term adverse outcomes. This work aimed to study the prevalence, risk factors, and impact on survival of postoperative (PO-AKI) and post-chemotherapy (PC-AKI) after colorectal cancer (CRC) surgery in Egyptian patients.
