Introduction: Thiamine is known to attenuate high-concentrate diet induced subacute ruminal acidosis (SARA) in dairy cows, however, the underlying mechanisms remain unclear. Objectives: The major objective of this study was to investigate the metabolic mechanisms of thiamine supplementation on high-concentrate diet induced SARA. Methods: Six multiparous, rumen-fistulated Holstein cows were used in a replicated 3 × 3 Latin square design...

Short bowel syndrome with intestinal failure is a rare disease with a massive impairment in quality of life, requiring a multidisciplinary team approach to medical, surgical, and nutritional therapy. Current pharmacological and surgical therapeutic options are limited; an important cornerstone is enteral and parenteral nutrition. The changed physiology of carbohydrate digestion plays a major role in the adaptation process and can be a target for specific enteral nutrition interventions. An important prognostic factor is the preservation of at least portions of the colon in continuity with small bowel...

D-lactic acidosis is an infrequent complication, mainly reported in patients with short bowel syndrome. It is characterized by recurrent episodes of encephalopathy with elevated serum D-lactic acid, usually associating metabolic acidosis. The presence of D-lactate-producing bacteria is necessary for the development of this complication. Other factors, such as the ingestion of large amounts of carbohydrates or reduced intestinal motility, contribute to D-lactic acidosis. We report a case of recurrent D-lactic acidosis in a 5-year-old girl with short bowel syndrome, due to a midgut volvulus...

PURPOSE: To suggest a simplified method for strong ion gap ([SIG]) calculation. PATIENTS AND METHODS: To simplify [SIG] calculation, we used the following assumptions: (1) the major determinants of apparent strong ion difference ([SIDa ]) are [Na+ ], [K+ ] and [Cl- ] (2) [Ca2+ ] and [Mg2+ ] do not contribute significantly to [SIDa ] variation and can be replaced by their reference concentrations (3) physiologically relevant pH variation is at the order of 10-2 and therefore we can assume a standard value of 7...

BACKGROUND: In this case report, we present a preterm newborn with persistent lactic acidosis who received total parenteral nutrition (TPN) that lacked thiamine. CASE PRESENTATION: A 28-week-old, 750 g female infant was born with an Apgar score of 8 at the 5th minute. Umbilical cord blood gas levels, including lactate level, were normal, and she was admitted to our neonatal intensive care unit (NICU). Achieving full enteral feeding was not possible due to gastric residues and abdominal distention, making the patient dependent on TPN during the first 2 weeks of life...

Type A lactic acidosis resulted from hypoxic mitochondrial dysfunction is an independent predictor of mortality for critically ill patients. However, current therapeutic agents are still in shortage and can even be harmful. This paper reviewed data regarding lactic acidosis treatment and recommended that pyruvate might be a potential alkalizer to correct type A lactic acidosis in future clinical practice. Pyruvate is a key energy metabolic substrate and a pyruvate dehydrogenase (PDH) activator with several unique beneficial biological properties, including anti-oxidant and anti-inflammatory effects and the ability to activate the hypoxia-inducible factor-1 (HIF-1α) - erythropoietin (EPO) signal pathway...

Subacute ruminal acidosis (SARA) can cause rapid lipopolysaccharide (LPS) elevation and milk yield decline in lactating ruminants. LPS has been shown to promote apoptosis and reduce the proliferation of mammary epithelial cells. Previous studies have shown that γ- amino butyric acid (GABA) can enhance production performance, regulating β-cell apoptosis and proliferation. Whether GABA can regulate apoptosis and proliferation induced by LPS in mammary epithelial cells is unknown. In this paper, we detected the role of GABA on proliferation and apoptosis as well as inflammation induced by LPS in bovine mammary epithelial cells (MAC-T cell line)...

Perinatal asphyxia is an event affecting around four million newborns worldwide. The 0.5 to 2 per 1000 of full term asphyxiated newborns suffer from hypoxic-ischemic encephalopathy (HIE), which is a frequent cause of death or severe disability and, as consequence, the most common birth injury claim for obstetrics, gynaecologists, and paediatricians. Perinatal asphyxia results from a compromised gas exchange that leads to hypoxemia, hypercapnia, and metabolic acidosis. In this work, we applied a metabolomics approach to investigate the metabolic profiles of urine samples collected from full term asphyxiated newborns with HIE undergoing therapeutic hypothermia (TH), with the aim of identifying a pattern of metabolites associated with HIE and to follow their modifications over time...

BACKGROUND: A novel pyruvate-based oral rehydration salt (Pyr-ORS) was demonstrated of superiority over bicarbonate- or citrate-based one to preserve organ function and correct lactic acidosis in rehydration of lethal shock in animals. This study further compared these effects between low-osmolar Pyr-ORS and equimolar citrate-based counterpart. METHODS: Eighty rats, using a fatal burn shock model, were randomized into four groups (two subgroups per group: n = 10): the sham group (group SR), Pyr-ORS group (group PR), WHO-ORS III group (group CR), and no rehydration group...

Many early studies laid the foundation for our understanding of the mechanics of chewing, the physiological role of chewing for the cow, and how chewing behavior is affected by dietary characteristics. However, the dairy cow has changed significantly over the past decades, as have the types of diets fed and the production systems used. The plethora of literature published in recent years provides new insights on eating and ruminating activity of dairy cows. Lactating dairy cows spend about 4.5 h/d eating (range: 2...

BACKGROUND: Current treatment options for chronic hepatitis B (CHB) are pegylated interferon alpha and nucleoside analogues (NAs). NAs have relatively fewer side effects than interferon alpha, and generally well tolerated. Previously 12.9% of patients on telbivudine treatment were reported to develop severe elevation of serum creatine phosphokinase (CPK) levels, but related clinical disease, like lactic acidosis (LA) and rhabdomyolysis (RM) were rare. The pathophysiology may be mitochondrial toxicity, for the NAs inhibit not only hepatitis B virus (HBV) polymerase, but also the host mitochondrial DNA polymerase γ...

Seven subunits of the mitochondrial contact site and cristae junction (CJ) organizing system (MICOS) in humans have been recently described in function and structure. QIL1 (also named MIC13) is a small complex that is crucial for the maintenance and assembling of MICOS. A novel mutation of an essential splice site in the C19orf70 gene encoding QIL1 induces severe mitochondrial encephalopathy, hepatopathy and lactate acidosis consistent with psychomotor retardation. In addition, bilateral kidney stones were observed...

Due to a lack of reference values for blood concentration of metformin in the literature, the forensic evaluation of metformin findings in blood samples is difficult. Interpretations with regard to the assessment of blood concentrations as well as an estimation of the ingested metformin amounts are often vague. Furthermore, post mortem evaluation of death due to lactic acidosis because of metformin is difficult since renal performance or lactate concentrations can not always reliably be determined after death...
