Objective: To investigate the effects of problem-based learning (PBL) in continuing medical education.
Data Sources: PubMed, MEDLINE, EMBASE, CINAHL, and ERIC databases were searched for randomized controlled trials published in English from January 2001 to May 2011 using key words problem-based learning, practice-based, self-directed, learner-centered, and active learning, combined with continuing medical education, continuing professional development, post professional, postgraduate, and adult learning.
Study Selection: Randomized controlled trials that described the effects of PBL on knowledge enhancement, performance improvement, participants' satisfaction, or patients' health outcomes were selected for analysis.
Synthesis: Fifteen studies were included in this review: 4 involved postgraduate trainee doctors, 10 involved practising physicians, and 1 had both groups. Online learning was used in 7 studies. Among postgraduate trainees PBL showed no significant differences in knowledge gain compared with lectures or non-case-based learning. In continuing education, PBL showed no significant difference in knowledge gain when compared with other methods. Several studies did not provide an educational intervention for the control group. Physician performance improvement showed an upward trend in groups participating in PBL, but no significant differences were noted in health outcomes.
Conclusion: Online PBL is a useful method of delivering continuing medical education. There is limited evidence that PBL in continuing education would enhance physicians' performance or improve health outcomes.

Association of Albumin-To-Creatinine Ratio With Diabetic Retinopathy Among US Adults (NHANES 2009-2016).

Department of Endocrinology and Metabolism, Second Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Objective: This study investigates the relationship between the albumin-to-creatinine ratio and diabetic retinopathy (DR) in US adults using NHANES data from 2009 to 2016. This study assesses the predictive efficacy of the urinary serum albumin-to-creatinine ratio (UACR/SACR Ratio) against traditional biomarkers such as the serum albumin-to-creatinine ratio (SACR) and urinary albumin-to-creatinine ratio (UACR) for evaluating DR risk. Additionally, the study explores the potential of these biomarkers, both individually and in combination with HbA1c, for early detection and risk stratification of DR.

Background: Groove pancreatitis (GP) is a form of pancreatitis that affects the pancreaticoduodenal groove area, which lies between the head of the pancreas, the second part of the duodenum and the distal bile duct, presenting as abdominal pain and gastric outlet obstruction. In this study, we present the clinical and radiological characteristics of individuals diagnosed with groove pancreatitis at our center and discuss the use of a conservative treatment approach in managing GP.
Methods: The data of patients with groove pancreatitis treated at our center between January 2012 and December 2021 was analyzed.
Low Utility of Routine Thyroid Function Testing for Bowel Symptoms: A Population-Based Assessment.

January 2025
Division of Gastroenterology, Hepatology and Endoscopy, Brigham and Women's Hospital, 75 Francis Street, Boston, MA, 02115, USA.
Background: Chronic constipation, diarrhea, and fecal incontinence (FI) are prevalent with significant impact on quality of life and healthcare utilization. Thyroid dysfunction was recognized as a potential contributor to bowel disturbances in selected populations, but the strength/consistency of this association remain unclear.
Aims: To investigate the relationship between thyroid function and bowel health measures (constipation, diarrhea, and FI) in a nationally representative sample of the U.
Impact of hemoadsorption with CytoSorb® on meropenem and piperacillin exposure in critically ill patients in a post-CKRT setup: a single-center, retrospective data analysis.

Purpose: CytoSorb® (CS) adsorbent is a hemoadsorption filter for extracorporeal blood purification often integrated into continuous kidney replacement therapy (CKRT). It is primarily used in critically ill patients with sepsis and related conditions, including cytokine storms and systemic inflammatory responses. Up to now, there is no evidence nor recommendation for the use of CS filters in sepsis (22).
