Acute pancreatitis (AP) is common and clinically complex, and persistent renal failure (PRF) is a severe complication. This study retrospectively analyzed 798 AP patients admitted within three days of onset and divided them into a PRF group (n = 111) and a non-PRF group (n = 687), comparing the characteristics of the two groups. Multivariate analysis showed that lactate (β = 0.340, P < 0.001, OR = 1.405) and lactate dehydrogenase (LDH, β = 0.002, P < 0.001, OR = 1.002) were significant risk factors for PRF. Stratified analysis indicated that patients with LDH ≥ 700 U/L and lactate ≥ 2 mmol/L had a higher incidence of PRF. The ROC curve analysis showed that the areas under the curve for lactate, LDH, and the combined lactate + LDH were 0.752, 0.828, and 0.866, respectively, with the highest diagnostic accuracy for the combined indicator. The characteristics of different risk groups showed that the incidence of PRF in the high-risk group was significantly higher than that in the low-risk group. The levels of lactate and LDH within 24 h of admission have a significant predictive effect on PRF in AP patients, which helps clinicians identify high-risk patients early and guide treatment decisions.

Indirect calorimetry (IC) is the gold standard for determining energy requirements. Resting energy expenditure (REE) equations could noninvasively estimate energy requirements in healthy individuals. Whether the published equations could accurately predict the REE of adults with nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) remains unclear. Here, we aimed to investigate the accuracy of predicted REE in patients with NAFLD and T2DM using different equations.

Slow transit constipation (STC), a subtype of functional constipation characterized by delayed colonic transit (> 72 h), imposes substantial physical and psychological burdens.
