Objective: To characterise and explore the development in the number and content of urine samples sent from general practice in the North Denmark Region to the Department of Clinical Microbiology (DCM) at Aalborg University Hospital during a five-year period.

Design: A register-based study.

Setting: General practice.

Subjects: Urine samples received at DCM, Aalborg University Hospital from general practice between 2017 and 2022.

Main Outcome Measures: Number and content of urine samples.

Results: A total of 255,271 urine samples from general practice were received at DCM, with 76.1% being from female patients. Uropathogens were identified in 43.0% of the samples. During the five-year period, a 23.0% increase in the number of urine samples per person (incidence rate ratio (IRR) 1.23, 95% CI 1.21-1.25) was observed. A slight increase in the proportion of positive cultures (risk ratio (RR) 1.03, 95% CI 1.01-1.05) was seen. No notable change in the patient population (age, gender) was observed. Overall, was the most identified uropathogen (60.4%) followed by spp. (8.7%) and spp. (7.7%). Distribution of the various uropathogens differed slightly depending on patient gender and age, importantly was less frequently observed in males aged >65 years.

Conclusion: During the past five years an increasing amount of urine cultures have been requested at DCM from general practice. Importantly, the cause(s) of this increasing demand needs to be explored further in future studies.

Introduction: What interventions effectively prevent postoperative stenosis following endoscopic resection (ER) of superficial esophageal cancer? This study aimed to identify effective interventions or combinations through a systematic review and network meta-analysis.

Methods: Six databases were systematically searched for eligible studies up to 30 April 2023, on interventions to prevent esophageal stenosis post-ER. Odds ratios (ORs) evaluated stenosis rate (primary outcome) and complications (secondary outcome), while mean differences (MD) evaluated endoscopic balloon dilatation (EBD) sessions post-stenosis.

Modulation of placental angiogenesis by metformin in a rat model of gestational diabetes.

Histochem Cell Biol

January 2025

Medical Histology and Cell Biology Department, Faculty of Medicine, Mansoura University, Mansoura, 35516, Egypt.

Gestational diabetes mellitus (GDM) significantly disrupts placental structure and function, leading to complications such as intrauterine growth restriction (IUGR) and preeclampsia. This study aimed to investigate the effects of GDM on placental histology, angiogenesis, and oxidative stress, as well as evaluate metformin's protective role in mitigating these changes. A total of 60 pregnant Sprague-Dawley rats were divided into four groups: control, metformin-treated, GDM, and GDM with metformin.

Mediation of modifiable risk factors in two multidomain dementia prevention trials.

Alzheimers Dement

January 2025

Department of Public and Occupational Health, Amsterdam UMC Location VUMC, Amsterdam, the Netherlands.

Introduction: We explored which dementia risk factors in two multidomain prevention trials mediate beneficial, neutral, or counteracting effects on dementia incidence.

Methods: We pooled data from the multidomain MAPT (Multidomain Alzheimer Preventive Trial; n = 1679, up to 5-year follow-up) and preDIVA trials (Prevention of Dementia by Intensive Vascular Care; n = 3526, up to 12-year follow-up) in adults aged 70+. We used multiple mediation analysis to quantify the role of 2-year changes in body mass index, systolic blood pressure, total cholesterol, and physical activity in the intervention effects on dementia incidence.

Objective: Revision surgeries for periprosthetic joint infections (PJIs) in arthroplasty can follow either one- or two-stage treatment protocols. Previous studies have reported similar reinfection rates and reductions in complication rates for both treatment options. However, the literature on the selection of one protocol is still controversial.
