Early intensive treatment to prevent kidney failure in post-traumatic rhabdomyolysis: Case report.

SAGE Open Med Case Rep 2019 3;7:2050313X19839529. Epub 2019 Apr 3.

Department of Intensive Care, "Pugliese-Ciaccio" General Hospital, Catanzaro, Italy.

Traumatic rhabdomyolysis is a clinical and biological syndrome secondary to lysis of striated muscle fibers resulting in extended musculoskeletal damage. An acute muscle damage causes the release of constituent elements of the sarcoplasmic reticulum, such as muscle enzymes, potassium, and myoglobin in plasma circulation; these conditions are at great risk of dangerous systemic complications for life such as hypovolemic shock, hyperkalemia, and acute kidney injury. We describe the case of a patient who suffered a severe musculoskeletal and vascular trauma with elevated creatine kinase values and myoglobinemia treated early with coupled plasma filtration adsorption in order to prevent kidney damage, associated with volume replacement, loop diuretics, and correction of metabolic acidosis.

Post-Renal Transplant Metabolic Acidosis: A Neglected Entity.

Indian J Nephrol 2019 Mar-Apr;29(2):116-121

Department of Nephrology, Government Stanley Hospital, The Tamilnadu DR MGR Medical University, Chennai, Tamil Nadu, India.

Metabolic acidosis is a prevalent yet overlooked entity among renal transplant recipients (RTRs) and incurs adverse effects on graft function. Although graft dysfunction and calcineurin inhibitor usage have been linked with renal tubular acidosis (RTA), there is no Indian data on prevalence or risk factors of post-transplant acidosis. A cross-sectional study was conducted on 106 adult RTRs, with a transplant duration of >6 months and an estimated glomerular filtration rate (GFR) >40 ml/min/1. Read More

Fetal electrocardiography ST analysis for intrapartum monitoring: a critical appraisal of conflicting evidence and a way forward.

Am J Obstet Gynecol 2019 Apr 10. Epub 2019 Apr 10.

In the past century, some areas of obstetric including intrapartum care have been slow to benefit from the dramatic advances in technology and medical care. Although fetal heart rate monitoring (cardiotocography, CTG) became available a half century ago, its interpretation often differs between institutions and countries, its diagnostic accuracy needs improvement, and a technology to help reduce the unnecessary obstetric interventions that have accompanied the CTG is urgently needed. During the second half of the 20 century, key findings in animal experiments captured the close relationship between myocardial glycogenolysis, myocardial workload, and ST changes, thus demonstrating that ST waveform analysis of the fetal ECG can provide information on oxygenation of the fetal myocardium and establishing the physiological basis for the use of ECG in intrapartum fetal surveillance.

Protection of Myocardial Ischemia-Reperfusion by Therapeutic Hypercapnia: a Mechanism Involving Improvements in Mitochondrial Biogenesis and Function.

J Cardiovasc Transl Res 2019 Apr 12. Epub 2019 Apr 12.

Department of Anesthesiology, The Heilongjiang Province Key Lab of Research on Anesthesiology and Critical Care Medicine, Second Affiliated Hospital of Harbin Medical University, Harbin, China.

Previous studies proposed that acidic reperfusion may be a protective strategy for myocardial ischemia-reperfusion therapy with potential of clinical transformation. In this study, we investigated whether therapeutic hypercapnia could mimic acidosis postconditioning in isolated hearts with a 30-min left coronary artery ligation-reperfusion model in rats. Therapeutic hypercapnia (inhalation 20% CO for 10 min) is cardioprotective with a strict therapeutic time window and acidity: it reduced the infarct ratio and serum myocardial enzyme and increased the myocardial ATP content.

NMDA receptors (NMDARs) are glutamate-gated ion channels involved in excitatory synaptic transmission and in others physiological processes such as synaptic plasticity and development. The overload of Ca ions through NMDARs, caused by an excessive activation of receptors, leads to excitotoxic neuronal cell death. For this reason, the reduction of Ca flux through NMDARs has been a central focus in finding therapeutic strategies to prevent neuronal cell damage. Read More

J Exp Biol 2019 Apr 11. Epub 2019 Apr 11.

Zoophysiology, Department of Bioscience, Aarhus University, Aarhus, Denmark

The swamp eel () uses its buccal cavity to air-breathe while the gills are strongly reduced. They burrow into mud during the dry season, are highly tolerant of air-exposure, and experience severe hypoxia in both their natural habitat and in aquaculture. To study their ability to compensate for respiratory acidosis, we implanted catheters to sample both arterial blood and urine during hypercapnia (4% CO) in either water and air, or during whole animal air-exposure.

Dynamic changes in rumen fermentation and bacterial community following rumen fluid transplantation in a sheep model of rumen acidosis: implications for rumen health in ruminants.

FASEB J 2019 Apr 11:fj201802456R. Epub 2019 Apr 11.

Laboratory of Gastrointestinal Microbiology, Jiangsu Key Laboratory of Gastrointestinal Nutrition and Animal Health, College of Animal Science and Technology, Nanjing Agricultural University, Nanjing, China.

Over the years, rumen fluid transplantation (RT) has been successfully applied to treat acute rumen acidosis in ruminants, but how it functions in the ruminal microbial homeostasis and host function remains largely unknown. Here, we investigated the dynamic changes of rumen fermentation and bacterial communities following RT and its beneficial effects on rumen epithelial morphology and function in a sheep model of rumen acidosis. The results showed that RT resulted in dynamic changes in rumen fermentation and increased the concentrations of total volatile fatty acid, acetate, propionate, and butyrate, but it decreased the levels of lactate and LPS in the rumen.

Ketoacidosis related to sodium glucose cotransporter 2 inhibitors after emergency coronary surgery.

Interact Cardiovasc Thorac Surg 2019 Apr 9. Epub 2019 Apr 9.

Department of Cardiovascular Surgery, Kitasato University School of Medicine, Sagamihara, Japan.

Sodium glucose cotransporter 2 inhibitors are currently widely used antihyperglycaemic medications that are considered to be associated with euglycaemic diabetic ketoacidosis. We report 2 cases of patients who received sodium glucose cotransporter 2 inhibitors until emergency coronary artery bypass grafting (CABG) and developed euglycaemic ketoacidosis after surgery; they were treated with sugar replenishment and insulin infusion. In one case, coronary angiography revealed a spastic change of the bypass graft possibly due to severe acidosis. Read More

Attenuation of Acute Renal Injury After the Post-resuscitation Administration of Doxycycline in Surviving Newborn Piglets With Severe Hypoxia-Reoxygenation.

Front Pediatr 2019 22;7:75. Epub 2019 Mar 22.

Department of Pediatrics, University of Alberta, Edmonton, AB, Canada.

Asphyxiated neonates often have myocardial dysfunction and renal insufficiency. Previously we demonstrated that doxycycline improved cardio-renal function through matrix metalloproteinase (MMP)-2 inhibition in an acute swine model of neonatal hypoxia-reoxygenation. The prolonged cardio-renal protective effects of doxycycline in neonates still remained unknown. Read More

Clinical and Molecular Perspectives of Monogenic Hypertension.

Curr Hypertens Rev 2019 Apr 9. Epub 2019 Apr 9.

Department of Physiology, Wayne State University School of Medicine and the John D. Dingell VA Medical Center, Detroit, Michigan, MI. United States.

Advances in molecular research techniques have enabled a new frontier in discerning the mechanisms responsible for monogenic diseases. In this review, we discuss the current research on the molecular pathways governing blood pressure disorders with a Mendelian inheritance pattern, each presenting with a unique pathophysiology. Glucocorticoid remediable aldosteronism (GRA) and apparent mineralocorticoid excess (AME) are caused by mutations in regulatory enzymes that induce increased production of mineralocorticoids or inhibit degradation of glucocorticoids, respectively.

Acid-base physiology over tidal periods in the mussel Mytilus edulis: size and temperature are more influential than seawater pH.

Proc Biol Sci 2019 Feb;286(1897):20182863

1 Biosciences, University of Exeter , Geoffrey Pope Building, Stocker Road, Exeter EX4 4QD , UK.

Ocean acidification (OA) studies to date have typically used stable open-ocean pH and CO values to predict the physiological responses of intertidal species to future climate scenarios, with few studies accounting for natural fluctuations of abiotic conditions or the alternating periods of emersion and immersion routinely experienced during tidal cycles. Here, we determine seawater carbonate chemistry and the corresponding in situ haemolymph acid-base responses over real time for two populations of mussel ( Mytilus edulis) during tidal cycles, demonstrating that intertidal mussels experience daily acidosis during emersion. Using these field data to parameterize experimental work we demonstrate that air temperature and mussel size strongly influence this acidosis, with larger mussels at higher temperatures experiencing greater acidosis.

Cofactors of wheat-dependent exercise-induced anaphylaxis do not increase highly individual gliadin absorption in healthy volunteers.

Clin Transl Allergy 2019 25;9:19. Epub 2019 Mar 25.

5Department of Dermatology and Allergy Biederstein, Technical University of Munich, Biedersteiner Strasse 29, 80802 Munich, Germany.

Background: In wheat-dependent exercise-induced anaphylaxis (WDEIA), cofactors such as exercise, acetylsalicylic acid (ASA), alcohol or unfavorable climatic conditions are required to elicit a reaction to wheat products. The mechanism of action of these cofactors is unknown, but an increase of gliadin absorption has been speculated. Our objectives were to study gliadin absorption with and without cofactors and to correlate plasma gliadin levels with factors influencing protein absorption in healthy volunteers. Read More
