A Case of COVID-19-Triggered Polymyositis Leading to Rhabdomyolysis.

SARS-COVID-19 is known to manifest with a wide variety of symptoms, most of which are respiratory. Myalgias are a common symptom of COVID-19, but cases of severe virus-induced inflammatory muscle injury leading to rhabdomyolysis and polymyositis have also been reported. Here, we present and discuss a case of a 56-year-old woman who presented with an initial presentation of COVID-19 infection with inflammatory polymyositis leading to rhabdomyolysis.

Significance of Chronic Kidney Disease on Morbidity and Mortality in Hospitalized Patients With COVID-19.

Background: Patients with comorbid illnesses are at risk for worse outcomes with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; COVID-19). Our research examined patients with chronic kidney disease (CKD) to establish whether it remains an independent risk factor for mortality and morbidity in patients with COVID-19.

Methods: We conducted a retrospective cohort study using an electronic patient database in 2020.

Climate crisis and nephrology: a review of climate change's impact on nephrology and how to combat it.

Unlabelled: Climate change is worsening with tangible effects on our healthcare system. This review aims to examine the repercussions of the climate change on nephrology and explore potential strategies to mitigate its impact. This review examines dialysis's environmental impact, resource recycling methods, and plant-based diets for kidney health.

Polypoid Lymphangiectasia in the Sigmoid Colon: A Case Report of a Rare Entity.

Intestinal polypoid lymphangiectasia is an uncommon disorder involving an improperly formed enteric lymphatic system. It is characterized by lymphatic vessel dilatation with impaired drainage or obstruction of the lymph from the intestine. In this report, we present a case of a 73-year-old male patient with chronic intermittent left lower quadrant abdominal pain for one year who was found to have a sigmoid colon polyp on a colonoscopy.

Plant-based diets and postprandial hyperkalemia.

This Letter to the Editor is a response to St-Jules and Fouque and their interpretation of postprandial hyperkalemia, especially regarding plant-based diets. Based on the reviewed literature review, potassium kinetic studies cited by the authors include only 1 study with a food-based intervention that actually showed reduced postprandial hyperkalemia with plant-based diets. The remainder of the studies used potassium salts or supplements that behave differently compared with whole plant foods.

Surface presentation of the noncanonical Wnt5a motif to cytotoxic CD8 T-cells promotes their mechanotransduction and activation.

We report here strategic functionalization of the Wnt5a mimetic peptide ligand Foxy5 on a polydimethylsiloxane elastomer substrate to enhance the mechanotransduction and activation of cytotoxic CD8 T cells by triggering the noncanonical Wnt signaling. This new mechanoregulatory ligand platform can be widely applied in the fundamental research of mechano-immunology and further the development of novel immunotherapies.
