    Electrolyte and Acid-Base Disturbances in End-Stage Liver Disease: A Physiopathological Approach.
    Dig Dis Sci 2017 May 13. Epub 2017 May 13.
    Department of Internal Medicine, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Tlalpan, 14080, Mexico City, Mexico.
    Electrolyte and acid-base disturbances are frequent in patients with end-stage liver disease; the underlying physiopathological mechanisms are often complex and represent a diagnostic and therapeutic challenge to the physician. Usually, these disorders do not develop in compensated cirrhotic patients, but with the onset of the classic complications of cirrhosis such as ascites, renal failure, spontaneous bacterial peritonitis and variceal bleeding, multiple electrolyte, and acid-base disturbances emerge. Hyponatremia parallels ascites formation and is a well-known trigger of hepatic encephalopathy; its management in this particular population poses a risky challenge due to the high susceptibility of cirrhotic patients to osmotic demyelination.

    Na(+)/HCO3(-) Cotransporter NBCn2 Mediates HCO3(-) Reclamation in the Apical Membrane of Renal Proximal Tubules.
    J Am Soc Nephrol 2017 Mar 9. Epub 2017 Mar 9.
    Department of Biophysics and Molecular Physiology, Key Laboratory of Molecular Biophysics of Ministry of Education, Huazhong University of Science and Technology School of Life Science and Technology, Wuhan, Hubei, China; and
    The kidney maintains systemic acid-base balance by reclaiming from the renal tubule lumen virtually all HCO3(-) filtered in glomeruli and by secreting additional H(+) to titrate luminal buffers. For proximal tubules, which are responsible for about 80% of this activity, it is believed that HCO3(-) reclamation depends solely on H(+) secretion, mediated by the apical Na(+)/H(+) exchanger NHE3 and the vacuolar proton pump. However, NHE3 and the proton pump cannot account for all HCO3(-) reclamation. Read More

    Dynamics of acid-base and hematological regulation in day 15 chicken embryos (Gallus gallus domesticus) exposed to graded hypercapnia and hypoxia.
    Respir Physiol Neurobiol 2017 May 9;239:55-63. Epub 2017 Feb 9.
    Developmental Integrative Biology, Department of Biological Sciences, University of North Texas, 1155 Union Circle #305220, Denton, TX 76203, USA.
    Most experiments examining acid-base regulation of chicken embryos have employed static, single time point measurements rather than dynamic, multiple time point measurements that might reveal additional components of developing acid-base regulation. Thus, we studied blood acid-base balance and hematology of day 15 chicken embryos under 24h exposure to graded hypercapnia (1%-7% CO2) accompanied by graded hypoxia (20% O2 down to 13% O2). Across all hypercapnic/hypoxic environments, respiratory acidosis occurred 2h after exposure in proportion to the magnitude of hypercapnia. Read More

    [Gitelman´s syndrome as common cause of hypokalemia and hypomagnesemia].
    Vnitr Lek 2016 ;62(Supplementum 6):78-83
    The Gitelman syndrome (GS) is an autosomal recessive disorder characterized by hypokalemic metabolic alkalosis and presence of hypocalciuria and hypomagnesemia. It is one of the most common congenital "salt-wasting" tubulo-pathies, where the impairment of function of the Na+-Cl- cotransporter (NCCT) in the distal convoluted tubule is primary and hypokalemia secondary. Hypomagnesemia is caused by the impairment of magnesium reabsorption through TRPM6 channel which is located just by NCCT. Read More

    [Metabolic acidosis in chronic kidney disease].
    Vnitr Lek 2016 ;62(Supplementum 6):30-39
    Metabolic acidosis (MAC) is a constant symptom of chronic kidney disease (CKD) in advanced stages. However, its onset and degree do not depend only on the decrease of glomerular filtration but also on tubular functions. Therefore, in patients with predominant tubulointerstitial involvement it may already appear in earlier stages of CKD, usually as MAC with normal anion gap. Read More

    [Clinical evaluation of acid-base status: Henderson-Hasselbalch, or Stewart-Fencl approach?]
    Cas Lek Cesk 2016 ;155(7):365-369
    Two approaches have been used in clinical evaluation the acid-base status: traditional (bicarbonate-centered) is based on the Henderson-Hasselbalch equation complemented by calculation of the anion gap, and more recent quantitative approach proposed by Stewart and Fencl. The latter method defines the three independent variables, which regulate pH. These include: the difference between the sum of charges carried by strong plasma cations and anions termed the strong ion difference - SID (decrease causes acidosis, and vice versa); the total concentration of the weak non-volatile acids [Atot] (inorganic phosphate and albumin, decrease causes alkalosis and vice versa), and pCO2.

    Lois Bates Acheson Veterinary Teaching Hospital, Magruder Hall, Oregon State University, 700 Southwest 30th Street, Corvallis, OR 97331, USA.
    Metabolic alkalemia is characterized by an increase in bicarbonate concentration and base excess, an increase in pH, and a compensatory increase in carbon dioxide pressure. This article outlines indications for analysis, reference ranges, causes, and clinical signs of metabolic alkalosis. Algorithms for evaluation of patients with acid-base disorders and metabolic alkalosis are included. Read More

    Long-term follow-up of composite bladder augmentation incorporating stomach in a multi-institutional cohort of patients with cloacal exstrophy.
    J Pediatr Urol 2017 Feb 28;13(1):43.e1-43.e6. Epub 2016 Oct 28.
    Division of Pediatric Urology, Riley Hospital for Children, Indiana University School of Medicine, Indianapolis, IN, USA.
    Introduction: Composite bladder augmentation, incorporating gastric and bowel segments, has the theoretical advantage of metabolic neutrality while potentially avoiding the morbidities of gastrocystoplasty, such as hematuria-dysuria syndrome. The most common indication for this operation is a paucity of bowel, such as in cloacal exstrophy. Despite several early descriptive studies of this technique, there are no reports, to date, of long-term follow-up in this population. Read More

    Implementation of a Simplified Regional Citrate Anticoagulation Protocol for Post-Dilution Continuous Hemofiltration Using a Bicarbonate Buffered, Calcium Containing Replacement Solution.
    Blood Purif 2016 19;42(4):349-355. Epub 2016 Nov 19.
    Critical Care and Perioperative Medicine Research Group, William Harvey Research Institute, Queen Mary University of London, London, UK.
    Background/aims: Recent updates to the Nikkiso Aquarius continuous renal replacement therapy (CRRT) platform allowed us to develop a post-dilution protocol for regional citrate anticoagulation (RCA) using standard bicarbonate buffered, calcium containing replacement solution with acid citrate dextrose formula-A as a citrate source. Our objective was to demonstrate that the protocol was safe and effective.

    Methods: Prospective audit of consecutive patients receiving RCA for CRRT within intensive care unit, who were either contraindicated to heparin or had poor filter lifespan (<12 h for 2 consecutive filters) on heparin. Read More

    Secondary elements of blood pH variation can influence the effort effectiveness based on adaptive changes within a group of elite athletes.
    Clujul Med 2016 20;89(4):506-512. Epub 2016 Oct 20.
    Epidemiology Department, University of Medicine and Pharmacy Tîrgu Mureş, Romania.
    Aim: pH is the direct indicator of the body reaction following the activities performed. Establishing precise correlations between pH and blood biochemical parameters might support the balancing of values during periods of marked physical activity.

    Method: We conducted a case study in a group of elite rowers. Read More
