Given the cancellation of all elective procedures with the COVID-19 crisis, many anesthesiology learners are assigned to stay at home, limiting opportunities to learn in the clinical environment. We report on a novel use of existing resources to structure a daily nationwide learning experience, using Kotter's change management model (KCMM) to drive the process.

Adipocytes (AD) respond to the biomechanical stimulation experienced in fat tissue under static stretch during prolonged sitting or lying. To investigate the effect of such chronic stimulation on adipocyte cell metabolism, we used an in vitro system to mimic the static stretch conditions. Under in vitro culture stretching, cells were analyzed at the single-cell level and we measured an increase in the projected area of the AD and higher content of lipid droplets. A decrease in the projected area of these cells' nucleus is associated with peroxisome proliferator-activated receptor-gamma expression and heterochromatin. This is the first study to reveal proteins that were altered under static stretch following a mass spectrometry analysis and main pathways that affect cell fate and metabolism. Bioinformatics analysis of the proteins indicated an increase in mitochondrial activity and associated pathways under static stretch stimulation. Quantification of the mitochondrial activity by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay and the ATPase related proteins specifically measured ATP5B indicated an increase in adipogenesis which points to a higher rate of cell metabolism under static stretch. In summary, our results elaborate on the metabolism of AD exposed to biomechanical stimulation, that is, associated with altered cellular protein profile and thereby influenced cell fate. The static stretch stimulation accelerated adipocyte differentiation through increased mitochondrial activity. Hence, in this study, we introduce a new perspective in understanding the molecular regulation of mechano-transduction in adipogenesis. © 2020 Wiley Periodicals, Inc.BACKGROUND AND OBJECTIVES Non-specific low back pain (LBP) is responsible for triggering increased biomarkers levels. In this way, photobiomodulation therapy (PBMT) may be an interesting alternative to treat these patients. One of the possible biological mechanisms of PBMT involved to decrease pain intensity in patients with musculoskeletal disorders is modulation of the inflammatory mediators' levels. The aim of this study was to evaluate the effects of PBMT compared with placebo on inflammatory mediators' levels and pain intensity in patients with chronic non-specific LBP. STUDY DESIGN/MATERIALS AND METHODS A prospectively registered, randomized triple-blinded (volunteers, therapists, and assessors), placebo-controlled trial was performed. Eighteen patients with chronic non-specific LBP were recruited and treated with a single session of active PBMT or placebo PBMT. The primary outcome of the study was serum prostaglandin E2 levels and the secondary outcomes were tumor necrosis factor-α, interleukin-6 levels, and pain intensity. All outcomes were measured before and after 15 minutes of treatment session. RESULTS PBMT was able to decrease prostaglandin E2 levels at post-treatment compared with placebo, with a mean difference of -1470 pg/ml, 95% confidence interval -2906 to -33.67 in patients with LBP. There was no difference between groups in the other measured outcomes. Patients did not report any adverse events. CONCLUSION Our results suggest that PBMT was able to modulate prostaglandin E2 levels, indicating that this may be one of the mechanisms involved in the analgesic effects of PBMT in patients with LBP.

Lasers in Surgery and Medicine published by Wiley Periodicals, Inc.This study is to investigate the clinical characteristics of late pregnancy with asymptomatic 2019 novel coronavirus disease (COVID-19) infection, evaluate the outcome of maternal and fetal prognosis, and identify the evidence of intrauterine vertical transmission. A 22-years-old pregnant woman with asymptomatic COVID-19 infection who was admitted to our hospital on 11 February 2020 was enrolled in this study. Clinical data including laboratory test results and chest computed tomography (CT) scanning were collected and reviewed. Diagnosis of late pregnancy with asymptomatic COVID-19 infection was made. Lumbar anesthesia for cesarean section was performed and a female baby was delivered uneventfully, with the Apgar score of 9 to 10 points. Three times of COVID-19 nucleic acid test for the baby was negative after delivery. The puerpera returned to normal after the operation and two times of throat swab COVID-19 nucleic acid test were all negative after antiviral therapy. We reported an asymptomatic COVID-19 pregnant woman with detailed clinical information and our result indicated that for late pregnant women with asymptomatic COVID-19 infection, there might be no intrauterine infection caused by vertical transmission. © 2020 Wiley Periodicals, Inc.The Indian Council of Medical Research (ICMR), recommended the use of hydroxychloroquine (HCQ) as a prophylactic against COVID-19 among health care workers and asymptomatic contacts of laboratory confirmed cases of COVID. This is widely criticised as a hastily taken step with political inclination and minimal evidence backing. In the current scenario, where there is mass fear against COVID-19, this recommendation has made the people to believe that it will kill the viruses. This has important public health implications which are discussed below. Better communication should have been planned to ensure everyone does not go out and buy it. However, as a nation of 1.3 billion, we need to capitalize on this opportunity to generate data and valuable evidence on the use of HCQ to beat this pandemic. All health care workers taking this drug should volunteer themselves to be part of a trial/observational study and get registered online to generate useful data related to its safety and efficacy and guide future recommendations.
