Context: Acidemia is a marker of prognosis in methanol poisoning, as well as compounding formate-induced cytotoxicity. Prompt correction of acidemia is a key treatment of methanol toxicity and methods to optimize this are poorly defined.
Objective: We studied the efficiency of acidemia correction by intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) in a mass outbreak of methanol poisoning.
Methods: The study was designed as observational cohort study. The mean time for an increase of 1 mmol/L HCO, 0.01 unit arterial blood pH, and the total time for correction of HCO were determined in IHD- and CRRT-treated patients.
Results: Data were obtained from 18 patients treated with IHD and 13 patients treated with CRRT. At baseline, CRRT group was more acidemic than IHD group (mean arterial pH 6.79 ± 0.10 versus 7.05 ± 0.10; p = 0.001). No association was found between the rate of acidemia correction and age, weight, serum methanol, lactate, formate, and glucose on admission. The time to HCO correction correlated with arterial blood pH (r= -0.511; p = 0.003) and creatinine (r = 0.415; p = 0.020). There was association between the time to HCO correction and dialysate/effluent and blood flow rates (r= -0.738; p < 0.001 and r= -0.602; p < 0.001, correspondingly). The mean time for HCO to increase by 1 mmol/L was 12 ± 2 min for IHD versus 34 ± 8 min for CRRT (p < 0.001), and the mean time for arterial blood pH to increase 0.01 was 7 ± 1 mins for IHD versus 11 ± 4 min for CRRT (p = 0.024). The mean increase in HCO was 5.67 ± 0.90 mmol/L/h for IHD versus 2.17 ± 0.74 mmol/L/h for CRRT (p < 0.001).
Conclusions: Our study supports the superiority of IHD over CRRT in terms of the rate of acidemia correction.

Background: The effect of acidemia on blood coagulation remains inadequately understood in veterinary medicine. Therefore, we assessed the effect of acidification of canine whole blood on coagulation and investigated whether acidemia-induced coagulopathy could be reversed by reversing acidemia.
Methods: Citrated whole blood samples were taken from six healthy Beagle dogs and categorized, based on pH adjustment, into neutral, weak acidemia (WA), strong acidemia (SA), and reversal from SA.

Objectives: To elucidate the outcomes of periviable infants receiving active care (AC) and explore perinatal factors associated with neurodevelopmental outcomes.
Methods: This is a single-center retrospective study on infants born at 22-25 weeks of gestation, all of whom received AC. A developmental quotient (DQ) ≥ 85 at corrected 18 months was judged as normal.

Currently, risk stratification calculators for acute pancreatitis (AP) can at best predict acute pancreatitis mortality at 12 hours from the presentation. Given the severe morbidity associated with AP, the identification of additional prognostic indicators, which may afford earlier prediction in length of stay (LOS) and mortality, is desired. Metabolic acidosis can be a prognostic marker for the severity of AP, and venous bicarbonate can reliably and accurately be substituted for arterial base deficit to detect metabolic acidosis.
