Summary: This study aims to identify the best population, intervention design, and assess between-group biochemical separation in preparation for a future phase III trial. The study includes 30 patients aged 18 and above who were admitted to the ICU within 48 hours, receiving vasopressor treatment, and presenting metabolic acidosis. The findings confirm the feasibility of a larger phase III trial on sodium bicarbonate.

Summary: This study found that sodium bicarbonate (SB) infusion did not have a beneficial effect on hospital mortality in AKI patients with metabolic acidosis overall. However, it was observed to have a significant correlation with improved hospital mortality in patients with high anion gap (AG) metabolic acidosis. Larger randomized controlled trials are needed to confirm these results.

Summary: Tris-hydroxymethyl aminomethane (THAM) is an amino alcohol used clinically to buffer acid loads and raise pH in acidotic conditions. Available since 2020 in the United States, THAM may have clinical utility in managing acid-base derangements in conditions such as liver transplantation and acute respiratory distress syndrome (ARDS). However, clinical evidence supporting its use is limited, and high-quality evaluations are necessary.

Summary: Metabolic acidosis in CKD patients is common and can contribute to disease progression and various complications, worsening patient prognosis. Currently, sodium bicarbonate is the main treatment for metabolic acidosis. The role of the new drug veverimer in metabolic acidosis therapy requires further study.

Summary: Sodium bicarbonate (SB) infusion does not reduce in-hospital mortality in severely ill children with metabolic acidosis and is associated with increased risk of hypernatraemia, hypokalaemia, and hypocalcaemia. Efforts should be focused on eliminating the causes of metabolic acidosis rather than using SB excessively.

Summary: This study aimed to investigate the effect of plasma acidosis on mechanical performance and whether bicarbonate supplementation can attenuate plasma acidosis and arterial oxygen desaturation in elite cyclists. The results showed that plasma acidosis was not associated with the decline of peak power output, and bicarbonate supplementation failed to improve arterial oxygen desaturation or mechanical performance.

Summary: The long-term prognosis of ICU survivors with severe acidemia upon admission is unknown. This study aimed to determine their long-term health-related quality of life and survival. The study found that the health-related quality of life was reduced in both the control and the sodium bicarbonate groups, especially in the physical domains. Survival rate after 5 years was 30%, with no significant difference between groups.

Summary: We report on cytocompatible, charged polyzwitterionic nanogels (PZNGs) that can efficiently fix and release bicarbonate anions for the treatment of metabolic acidosis. The PZNGs show good stability and cytocompatibility, and exhibit sustained release of bicarbonate anions for up to 168 hours.

Summary: This systematic review and meta-analysis examined the effects of sodium bicarbonate on systolic blood pressure and antihypertensive medication use in individuals with chronic kidney disease (CKD). The results suggest that sodium bicarbonate supplementation does not adversely affect systolic blood pressure in CKD patients and does not increase the use of antihypertensive medication.

Summary: The study aimed to evaluate the reliability and validity of a 30-second maximal tethered freestyle swimming test (TST) in relation to swimming performance, as well as its associations with a land-based anaerobic test (WAnT). Results showed strong reliability and moderate correlations between TST and swimming performance, suggesting its potential use as an assessment tool in competitive swimming training programs.

Summary: Anaerobic resistance training (ART) appears to have a protective effect against the gastric motility and cardiovascular side effects induced by dexamethasone. Dexamethasone resulted in weight loss, reduced food intake, tachycardia, and decreased gastric emptying, while ART partially alleviated these negative impacts.

Summary: This study investigates the effects of LP-PII-IAA derived from the latex of Calotropis procera on irinotecan-induced intestinal mucositis. The results show that animals treated with LP-PII-IAA had reduced mortality, absence of diarrhea, and normalized intestinal functions. These effects were accompanied by decreased inflammation and oxidative stress markers. The findings suggest that the peptidases from C. procera are instrumental in suppressing the adverse effects of irinotecan.

Summary: This paper proposes a method for simultaneous tuning of cascade controllers to improve system performance under load disturbance. By formulating a cost function for a nonlinear optimization problem and defining robustness constraints, designers can explicitly and independently address the trade-off between performance and robustness. Simulation and experimental results demonstrate that the proposed method successfully reduces the integrated absolute error under load disturbance.

Summary: This is a cross-sectional study that compares women with obesity (n = 80) to a control group (n = 94). The study found that women with obesity had higher levels of GPx and TBARS, and lower levels of SOD compared to the control group. The obese women also showed higher concentrations of cortisol in their serum and urine, as well as lower levels of zinc, selenium, and magnesium, and increased excretion of these minerals in their urine. Additionally, there were correlations between cortisol/cortisone ratio and zinc and selenium concentrations, as well as positive correlations between GPx and SOD activity and zinc and selenium concentrations. However, the study was unable to determine the impact of these findings on the antioxidant defense system and insulin sensitivity.

Summary: In this study, the relationship between phase angle (PhA), consumption of ultra-processed foods, oxidative stress, body composition, and biochemical parameters in patients with inflammatory bowel diseases (IBD) was investigated. The results showed that PhA was positively correlated with glutathione (GSH) and superoxide dismutase (SOD). IBD patients consumed higher amounts of ultra-processed foods, but had better consumption of unprocessed or minimally processed foods. Additionally, the consumption of ultra-processed foods was positively correlated with malondialdehyde (MDA) levels.

Summary: This study aimed to investigate the involvement of the P2X7 receptor blocker Brilliant Blue G (BBG) in gastric emptying and oxidative stress changes in the gastrointestinal tract of spontaneously hypertensive rats (SHR), and to study its relationship with the renin-angiotensin system. The results showed that BBG improved gastric emptying delay and oxidative stress markers in SHR animals, and this preventive effect was abrogated by the renin-angiotensin system.
