Binge-eating and sodium bicarbonate: a potent combination for gastric rupture in adults—two case reports and a review of literature

Abstract Background: Disruptive eating habits, which include binge-eating, can often result in severe medical disorders, which are at times fatal. Following binge eating, dyspepsia and bloating are typical signs. However, sodium bicarbonate has been shown to cause acute gastric dilatation and spontaneous gastric rupture in the case of spontaneous gastric rupture. Methods We report two cases of spontaneous gastric leaks following the intake of sodium bicarbonate containing antacids following a large meal, as well as a review of similar cases. Around half of the cases were related to eating disorders, with higher incidence in females and a high mortality rate. In the 36 cases, sodium bicarbonate ingestion was associated with ten cases. Acute gastric dilatation with perforation necessitates definitive surgical intervention. Following an episode of binge-eating, there should be a low threshold of suspicion for patients with severe abdominal pain and abdominal distension.

Attenuating the virulence of the resistant superbug Staphylococcus aureus bacteria isolated from neonatal sepsis by ascorbic acid, dexamethasone, and sodium bicarbonate

We wanted to investigate the use of FDA-approved products ascorbic acid, dexamethasone, and sodium bicarbonate to reduce the virulence of the staphylococcus aureus bacteria that causes neonatal sepsis in this study and seek out natural alternatives to the problem of multi-drug resistance in this research. In Staphylococcus aureus, methods were tested phenotypically and genotypically for their effects on virulence factors and virulence-encoding genes. qRT-PCR was used to determine relative expression levels of all tested genes at the molecular level, including crtM, sigB, sarA, hla, fnbA, and icaA genes that control virulence factors production. Conclusions The new results show that ascorbic acid, dexamethasone, and sodium bicarbonate have potent anti-virulence activities against Staphylococcus aureus.

Protective Role of IRBIT on Sodium Bicarbonate Cotransporter-n1 for Migratory Cancer Cells

The IP3 receptor-binding protein released with IP3 interacts with a variety of ion channels and transporters. The effect of IRBIT on NBCn1 and its connection to cancer cell migration is unclear. Due to IRBIT-induced changes in NBCn1, we therefore wanted to determine the effect of IRBIT on NBCn1 and the restriction of cancer cell migration due to IRBIT-induced changes in NBCn1 production. Overexpression of IRBIT boosted cancer cell migration and NBC activity. By recruiting IRBIT, a stimulation with oncogenic epidermal growth factor boosted the expression of NBCn1 and cell migration of cancer cells. An effective tactic for attenuating cancer metastasis can be combined with IRBIT and NBCn1.

Effect of Ultrasound-Assisted Sodium Bicarbonate Treatment on Aggregation and Conformation of Reduced-Salt Pork Myofibrillar Protein

Likewise, the fluorescence intensity decreased from 894 to 623, and the fluorescence peak showed a significant decline, indicating that the ultrasound-assisted sodium bicarbonate treatment revealed the non-polarity of the microenvironment in which the fluorescence emission group was based, contributing to the microenvironment and protein structure of myofibrillar tryptophan's attempt to be modified. Overall, ultrasound-assisted sodium bicarbonate therapy may be able to significantly raise pork myofibrillar protein solubility and change the protein structure in a reduced-salt environment.

Elucidation of the bicarbonate binding site and insights into the carboxylation mechanism of ( N 5 )-carboxyaminoimidazole ribonucleotide synthase (PurK) from Bacillus anthracis

In the active site, structures of a -carboxyaminoinucleotide synthase from Bacillus anthracis are displayed with various combinations of ATP, ADP, Mg 2+, bicarbonate, and amino imidazole ribonucleotide synthase. The binding site of bicarbonate has only been speculated on before, but it is on view here for the first time.

Calcium and Bicarbonate Signaling Pathways have Pivotal, Resonating Roles in Matching ATP Production to Demand

Summary of Mitochondrial ATP manufacture in cardiac ventricular myocytes must be continually adjusted to properly replenish the ATP consumed by the working heart. A bicarbonate-activated adenylyl cyclase, a soluble adenylyl cyclase, is a bicarbonate-activated adenylyl cyclase. By enabling local EPAC1 which turns on Rap1, this cAMP signaling cascade is shown to operate inside the mitochondrial intermembrane space. We also show that this third signaling process involving bicarbonate and sAC activates the cardiac mitochondrial ATP production machinery by working autonomous of, yet in conjunction with, [Ca 2+] m -dependence ATP production to satisfy the energy requirements of both health and disease. [Ca 2+] m signaling arms tune mitochondrial ATP production to match the full range of energy intake in cardiac ventricular myocytes.

Effects of Calcium, Lanthanum, and Bicarbonate Ion on Epinephrine Modification of Insulin Release In Vitro

In the in vitro perifusion method, calcium flux regulation of insulin release was investigated by using lanthanum, an inhibitor of calcium flux. In the absence of bicarbonate ion, the effect of epinephrine prestimulation on insulin secretion is reversed by epinephrine priming in the absence of bicarbonate is highly variable: insulin secretion's response to a subsequent glucose challenge is likely to reduced calcium uptake.

Metabolic Effects of Sodium Bicarbonate in Management of Diabetic Ketoacidosis

With the following exceptions, a comparison of previously published results from a similar group of patients treated with insulin and saline alone showed no significant differences in blood or cerebrospinal fluid with the exceptions. The decrease in CSF osmolality in patients receiving only insulin and saline was considerably smaller after insulinsaline-bicarbonate therapy than in patients receiving only insulin and saline. In both groups with therapy, pH values decreased in both groups with therapy, but they were markedly lower in the group receiving insulin-saline-bicarbonate. Except for the unexplained decrease in CSF osmolality, the use of sodium bicarbonate did not significantly change the clinical course of the nine patients studied, except for the unexplained slower decline in CSF osmolality.

Streptolysin S targets the sodium-bicarbonate cotransporter NBCn1 to induce inflammation and cytotoxicity in human keratinocytes during Group A Streptococcal infection

SLS has previously shown that hemolysis can be induced by targeting the chloride-bicarbonate exchanger Band 3 in erythrocytes, indicating that SLS can be effective in targeting host proteins to promote cell lysis. During GAS infection, we use bioinformatics analysis and chemical inhibition studies to show that SLS targets the electroneutral sodium-bicarbonate cotransporter NBCn1 in keratinocytes. In addition, treating keratinocytes with SLS decreases the ability of host cells to control their intracellular pH, and this can be monitored in real time using the pH-sensitive dye pHrodo Red AM in live imaging studies. These findings reveal that SLS is a multifunctional bacterial toxin that GAS uses in a variety of context-dependent ways to promote host cell cytotoxicity and disease severity in a variety of context-dependent ways. SLS host targets have the ability to influence the design of drugs for severe GAS infections, according to studies that have helped clarify additional host targets.
