Wellcome Open Res 2020 26;5:51. Epub 2020 Mar 26.

Krankenanstalt Rudolfstiftung, Messerli Institute, Vienna, 1180, Austria.

Stroke-like episodes (SLEs) are a hallmark of mitochondrial encephalopathy, lactic acidosis, and stroke-like episode (MELAS) syndrome but occur in other mitochondrial disorders (MIDs) as well. The morphological equivalent of the SLE is the stroke-like lesion (SLL) on magnetic resonance imaging (MRI). The pathophysiology of SLLs is under debate, but several hypotheses have been raised to explain the phenomenon. Read More

Compromised regulation of the rat brain parenchymal arterioles in vasopressin-associated acute hyponatremia.

Microcirculation 2020 Jun 30. Epub 2020 Jun 30.

Laboratory of Experimental and Clinical Neurosurgery, Mossakowski Medical Research Centre, Polish Academy of Sciences, Warsaw, Poland.

Objective: In this study, we examined the effect of acute hyponatremia associated with vasopressin (AVP) on the responses of the isolated rat's middle cerebral arteries (MCAs) and parenchymal arterioles (PAs) to acidosis, nitric oxide donor (SNAP) and to endothelium-dependent vasodilator adenosine triphosphate (ATP).

Methods: The studies were performed on isolated, perfused and pressurized MCAs and PAs in control conditions and during AVP-associated hyponatremia. Hyponatremia was induced in vitro by lowering Na concentration from 144 to 121 mM in intra- and extravascular fluid in the presence of AVP. Read More

A Korean child diagnosed with malonic aciduria harboring a novel start codon mutation following presentation with dilated cardiomyopathy.

Mol Genet Genomic Med 2020 Jun 30:e1379. Epub 2020 Jun 30.

Department of Laboratory Medicine, Kyung Hee University School of Medicine, Seoul, Korea.

Background: Malonic aciduria (MA, OMIM#248360) is an extremely rare inherited metabolic disorder caused by the deficiency of malonyl-CoA decarboxylase. The phenotype exhibited by patients with MA is variable, but may include symptoms, such as developmental delay in early childhood, seizures, vomiting, metabolic acidosis, hypoglycemia, ketosis, and cardiomyopathy. We describe the first case of a Korean child with MA who presented with dilated cardiomyopathy (DCMP) at the age of 3 months. Read More

Impact of high plasma concentrations of linezolid in Taiwanese adult patients- therapeutic drug monitoring in improving adverse drug reactions.

J Formos Med Assoc 2020 Jun 26. Epub 2020 Jun 26.

Graduate Institute of Clinical Pharmacy, College of Medicine, National Taiwan University, Taipei, Taiwan; Department of Pharmacy, National Taiwan University Hospital, Taipei, Taiwan; School of Pharmacy, College of Medicine, National Taiwan University, Taipei, Taiwan. Electronic address:

Background: Previous studies have shown that the development of thrombocytopenia was associated with the elevated plasma concentration of linezolid, but little is known about the relationship between other uncommon adverse drug reactions (ADRs) and plasma concentration. The appropriate dosing adjustment has remained controversial. This prospective observational study was conducted to investigate the association between the plasma concentration of linezolid, ADRs, and clinical outcomes. Read More

Nutritional management of celiac crisis in an elderly adult: A case report of the rare presentation of celiac disease in a 75-y-old woman.

Nutrition 2020 May 19;79-80:110858. Epub 2020 May 19.

Unit of Dietetic and Clinical Nutrition, University Hospital Maggiore della Carità, Novara, Italy.

In adults, a very uncommon presentation of celiac disease (CD) is a celiac crisis, a life-threatening and severe form of the disease having a dramatic onset with diarrhea and metabolic acidosis with electrolyte and fluid imbalance. Treatment of celiac crisis requires a gluten-free diet; however, the risk for refeeding syndrome (RFS) should be considered in patients showing marked malabsorption symptoms and important unintentional weight loss. Therefore, to avoid metabolic and potentially fatal complications of re-nutrition, nutritional management is crucial for a safe recovery after a celiac crisis. Read More

Alterations in fermentation parameters during and after induction of a subacute rumen acidosis in the rumen simulation technique.

J Anim Physiol Anim Nutr (Berl) 2020 Jun 28. Epub 2020 Jun 28.

Institute for Physiology and Cell Biology, University of Veterinary Medicine Hannover, Hannover, Germany.

Subacute rumen acidosis (SARA) is a common problem in dairy cattle. High-concentrate rations lead to an accumulation of short-chain fatty acids (SCFA) in the rumen and a subsequent decrease in ruminal pH. As SARA impairs animal welfare and productivity, numerous in vivo studies are focusing on evaluation of prevention strategies. Read More

Lactic Acidosis in the Presence of Glucose Diminishes Warburg Effect in Lung Adenocarcinoma Cells.

Front Oncol 2020 12;10:807. Epub 2020 Jun 12.

Department of Chronic-Degenerative Diseases, National Institute of Respiratory Diseases "Ismael Cosío Villegas", Mexico City, Mexico.

Lactic acidosis (3 to 40 mM, pH < 6.9) is a condition found in solid tumors because tumor cells have a high rate of glucose consumption and lactate production even in the presence of oxygen; nevertheless, the microenvironment might still provide a sufficient glucose supply. Lactic acidosis has been proposed to shift metabolism from aerobic glycolysis toward oxidative phosphorylation (OXPHOS). Read More

Intraoperative renal replacement therapy for liver transplantation: Is there really a benefit?

Liver Transpl 2020 Jun 27. Epub 2020 Jun 27.

Seattle, Washington, United States.

Acute kidney injury at the time of liver transplantation( LT) is associated with increased mortality, particularly for those patients who require hemodialysis (Zand). There are several theoretical benefits of intraoperative RRT (IORRT). Dialysis can correct metabolic acidosis and electrolyte abnormalities including hyperkalemia common during liver transplantation, particularly during the anhepatic phase can reduce fluid overload, especially when large amounts of blood product transfusions are administered.

Renal Tubular Acidosis.

Indian J Pediatr 2020 Jun 26. Epub 2020 Jun 26.

Division of Nephrology, Department of Pediatrics, All India Institute of Medical Sciences, New Delhi, 110029, India.

Renal tubular acidosis (RTA) comprises a group of disorders characterized by low capacity for net acid excretion and persistent hyperchloremic metabolic acidosis, despite preserved glomerular filtration rate. RTA are classified into chiefly three types (1, 2 and 4) based on pathophysiology and clinical and laboratory characteristics. Most patients have primary RTA that presents in infancy with polyuria, growth retardation, rickets and/or hypotonia. Read More

Exploiting metabolic acidosis in solid cancers using a tumor-agnostic pH-activatable nanoprobe for fluorescence-guided surgery.

Nat Commun 2020 Jun 26;11(1):3257. Epub 2020 Jun 26.

Departments of Surgery, Nuclear Medicine and Molecular Imaging, Medical Imaging Center Groningen, University of Groningen, University Medical Center Groningen, Groningen, The Netherlands.

Cancer cell metabolism leads to a uniquely acidic microenvironment in solid tumors, but exploiting the labile extracellular pH differences between cancer and normal tissues for clinical use has been challenging. Here we describe the clinical translation of ONM-100, a nanoparticle-based fluorescent imaging agent. This is comprised of an ultra-pH sensitive amphiphilic polymer, conjugated with indocyanine green, which rapidly and irreversibly dissociates to fluoresce in the acidic extracellular tumor microenvironment due to the mechanism of nanoscale macromolecular cooperativity.
