Objective: Cardiothoracic surgery is a large field in Australia, and evidence suggests post-cardiopulmonary bypass (CPB) hyperlactataemia is associated with higher morbidity and mortality. Low thiamine levels are a potentially common yet treatable cause of hyperlactataemia and may occur in the setting of exposure to CPB non-biological material. We hypothesized that cardiopulmonary bypass would result in decreased whole-blood thiamine levels, which may therefore result in increased whole-blood lactate levels in the post-operative period.
Methods: Adult patients undergoing non-emergent CPB were recruited in a single centre, prospective, analytic observational study at Townsville University Hospital, Australia. The primary outcome was a comparison of pre- and post-CPB thiamine diphosphate level, secondarily aiming to assess any relationship between lactate and thiamine levels. Prospective pre- and post-CPB blood samples were taken and analysed at a central reference laboratory.
Results: Data was available for analysis on 78 patients. There was a statistically significant increase in thiamine diphosphate level from pre-CPB: 1.36 nmol/g Hb, standard deviation (SD) 0.31, 95% confidence intervals (CI) 1.29-1.43, to post-CPB: 1.77 nmol/g Hb, SD 0.53, 95% CI 1.43-1.88, p value < 0.001. There was a non-statistically significant (p > 0.05) trend in rising whole-blood lactate levels with increasing time. Analysis of lactate levels at varying time periods found a significant difference between baseline measurements and increased levels at 13-16 h (p < 0.05). There was no significant relationship observed between whole-blood thiamine levels and post-operative lactate levels.
Conclusion: Whole-blood thiamine levels were found to increase immediately post-CPB in those undergoing elective cardiac surgery. There was no correlation between whole-blood thiamine levels and post-operative arterial lactate levels.

Thiamine Deficiency Is Common and Underrecognized in Emergency Department Oncology Patients.

: Wernicke's encephalopathy can occur in oncology patients independent of alcohol use, likely resulting from poor dietary thiamine intake. High metabolic demands, such as those in acute illnesses seen in the emergency department (ED), can exacerbate thiamine deficiency. In this study, our objective was to assess the incidence of thiamine deficiency in ED oncology patients, which could lead to Wernicke's encephalopathy or other thiamine deficiency disorders if left untreated.

Background/objectives: The rise in chronic metabolic diseases has led to the exploration of alternative diets. The carnivore diet, consisting exclusively of animal products, has gained attention, anecdotally, for imparting benefit for inflammatory conditions beyond that possible by other restrictive dietary approaches. The aim was to assess the micronutrient adequacy of four versions of the carnivore diet against national nutrient reference values (NRVs).

Objective: To observe the clinical efficacy of vitamin B1 in patients with ICU-acquired weakness (ICU-AW).
Methods: A retrospective analysis was conducted to select ICU-AW patients treated with vitamin B1 in the intensive care unit (ICU) of Shanghai East Hospital, Tongji University from July 2022 to December 2023. Propensity score matching was used to match the control group and observation group at a 1 : 1 ratio, considering differences in patient age, gender, and acute physiology and chronic health evaluation II (APACHE II).

Background and objective Vitamin C and thiamine possess properties that may mitigate the harmful effects of sepsis. However, there is a dearth of studies in the literature comparing these two vitamins with each other and with a placebo regarding their efficacy against sepsis. This study aimed to investigate the outcomes associated with high-dose infusions of vitamin C and thiamine in septic patients, thereby seeking to contribute valuable insights into the optimal management of sepsis.
