Is blood agar an alternative to sabouraud dextrose agar for the isolation of fungi in patients with mycotic keratitis

To compare the blood agar (BA), sabouraud dextrose agar (SDA) and chocolate agar (CA) for the isolation of fungi in patients with mycotic keratitis. Corneal Scrapings of 229 patients with clinically diagnosed microbial keratitis were inoculated on BA, SDA, CA. The culture media were evaluated for the rate and time taken for the fungal growth. Seventy six of 229 patients had fungal keratitis. Fungus grew on BA in 60/76(78.9 %), on SDA in 76/76 (100 %), on CA in 40/76(52.6 %) patients. The fungi which grew on BA (60/76) also grown on SDA at the same time. The colony morphologies of different fungi were better on SDA than BA/CA. Among the different culture media, SDA is essential for the isolation fungi in patients with mycotic keratitis.     

Telemedicine to deliver diabetes care in low- and middle-income countries: a systematic review and meta-analysis

ObjectiveTo determine the effectiveness of telemedicine in the delivery of diabetes care in low- and middle-income countries.MethodsWe searched seven databases up to July 2020 for randomized controlled trials investigating the effectiveness of telemedicine in the delivery of diabetes care in low- and middle-income countries. We extracted data on the study characteristics, primary end-points and effect sizes of outcomes. Using random effects analyses, we ran a series of meta-analyses for both biochemical outcomes and related patient properties.FindingsWe included 31 interventions in our meta-analysis. We observed significant standardized mean differences of −0.38 for glycated haemoglobin (95% confidence interval, CI: −0.52 to −0.23; I² = 86.70%), −0.20 for fasting blood sugar (95% CI: −0.32 to −0.08; I² = 64.28%), 0.81 for adherence to treatment (95% CI: 0.19 to 1.42; I² = 93.75%), 0.55 for diabetes knowledge (95% CI: −0.10 to 1.20; I² = 92.65%) and 1.68 for self-efficacy (95% CI: 1.06 to 2.30; I² = 97.15%). We observed no significant treatment effects for other outcomes, with standardized mean differences of −0.04 for body mass index (95% CI: −0.13 to 0.05; I² = 35.94%), −0.06 for total cholesterol (95% CI: −0.16 to 0.04; I² = 59.93%) and −0.02 for triglycerides (95% CI: −0.12 to 0.09; I² = 0%). Interventions via telephone and short message service yielded the highest treatment effects compared with services based on telemetry and smartphone applications.ConclusionAlthough we determined that telemedicine is effective in improving several diabetes-related outcomes, the certainty of evidence was very low due to substantial heterogeneity and risk of bias.     

Moving a mountain: Practical insights into mastering a major curriculum reform at a large European medical university

Abstract

Aim: Undergraduate medical education is currently in a fundamental transition towards competency-based programs around the globe. A major curriculum reform implies a dual challenge: the change of the curriculum and the delivering organization. Both are closely interwoven. In this article, we provide practical insights into our approach of managing such a fundamental reform of the large undergraduate medical program at the Charité – Universitätsmedizin Berlin.

Methods: Members of the project management team summarized the key features of the process with reference to the literature.

Results: Starting point was a traditional, discipline-based curriculum that was reformed into a fully integrated, competency-based program. This change process went through three phases: initiation, curriculum development and implementation, and sustainability. We describe from a change management perspective, their main characteristics, and the approaches that were employed to manage them successfully.

Conclusions: Our report is intended to provide practical insights and guidance for those institutions which are yet considering or have already started to undergo a major reform of their undergraduate programs towards competency medical education.     

Perioperative evaluation of regional aortic wall shear stress patterns in patients undergoing aortic valve and/or proximal thoracic aortic replacement

Objectives

To assess in patients with aortopathy perioperative changes in thoracic aortic wall shear stress (WSS), which is known to affect arterial remodeling, and the effects of specific surgical interventions.
