Mucosal Inflammation Program, University of Colorado Anschutz Medical Campus; Department of Medicine, University of Colorado Anschutz Medical Campus; Rocky Mountain Regional Veterans Affairs Medical Center;

Early accumulation of neutrophils (PMN) is a hallmark of acute intestinal inflammation. This acute inflammation is either resolved or progresses to chronic inflammation. Without efficient PMN clearance at sites of infiltration, PMN can accumulate and contribute to chronic inflammatory conditions, including the intestinal diseases ulcerative colitis (UC) and Crohn's Disease (CD).

Pediatr Nephrol 2021 Jun 18. Epub 2021 Jun 18.

Department of Renal Medicine, University College London, NW3 2PF, London, UK.

Evolution moves in mysterious ways. Excretion of waste products by glomerular filtration made perfect sense when life evolved in the ocean. Yet, the associated loss of water and solutes became a problem when life moved onto land: a serious design change was needed and this occurred in the form of ever more powerful tubules that attached to the glomerulus.

CRRT-associated ketoacidosis: A series of 5 cases.

Clin Nephrol 2021 Jun 18. Epub 2021 Jun 18.

Continuous renal replacement therapy (CRRT) is a dialysis modality used in critically ill patients with acute kidney injury (AKI). Although most dialysate and replacement fluids are dextrose-containing, CRRT-associated hypophosphatemia sometimes warrants the use of phosphorus-containing solutions which are dextrose free. The other less commonly used dextrose-free dialysate solutions are certain formulations of Prismasol and Prismasate. Read More

Brugada Pattern Phenocopy Induced by Diabetic Ketoacidosis.

Cureus 2021 May 16;13(5):e15066. Epub 2021 May 16.

Interventional Cardiology, Unity Health, Searcy, USA.

Brugada syndrome is a congenital cardiac channelopathy characterized by ST-segment elevation (≥2 mm) and subsequent inverted T wave in a minimum of two right precordial leads (Brugada type 1 ECG [electrocardiogram] pattern) on ECG. Brugada syndrome is estimated to be responsible for 4%-12% of all sudden cardiac deaths and up to 20% in patients with structurally normal hearts. Development of a temporary Brugada pattern, known as Brugada phenocopy, has been observed in individuals presenting with reversible underlying conditions such as hyperkalemia, hyponatremia, acidosis, ischemia, and pulmonary embolism, among others.

BMJ Case Rep 2021 Jun 15;14(6). Epub 2021 Jun 15.

Internal Medicine, Allama Iqbal Medical College, Lahore, Pakistan.

Simultaneous occurrences of diabetic ketoacidosis (DKA) and thyroid storm have long been known, but only a few cases have been reported to date. Both these endocrine emergencies demand timely diagnosis and management to prevent adverse outcomes. Due to the similarities in their clinical presentation, DKA can mask the diagnosis of thyroid storm and vice versa. Read More

Acid-Induced Inflammatory Cytokines in Osteoblasts: A Guided Path to Osteolysis in Bone Metastasis.

Front Cell Dev Biol 2021 28;9:678532. Epub 2021 May 28.

Biomedical Science and Technologies Lab, IRCCS Istituto Ortopedico Rizzoli, Bologna, Italy.

Bone metastasis (BM) is a dismal complication of cancer that frequently occurs in patients with advanced carcinomas and that often manifests as an osteolytic lesion. In bone, tumor cells promote an imbalance in bone remodeling via the release of growth factors that, directly or indirectly, stimulate osteoclast resorption activity. However, carcinoma cells are also characterized by an altered metabolism responsible for a decrease of extracellular pH, which, in turn, directly intensifies osteoclast bone erosion. Read More
