Abstract
Some patients with heatstroke also experience intracerebral hemorrhage (ICH). However, clinical case reports of heatstroke-induced ICH are rare. The risk factors for cerebral hemorrhage after heatstroke remain unknown. The present study evaluated the clinical characteristics and risk factors of patients with heatstroke-related ICH. In this retrospective observational study, we collected data on all ICHs after heatstroke occurred between 2012 and 2022. The characteristics of patients with heatstroke-induced ICH were described. The risk factors for cerebral hemorrhage after heatstroke were examined using logistic regression analysis. In total, 177 patients were included in this study, and 11 patients with ICH secondary to heatstroke were identified. Variables with P values of <.05 in univariate models, comparing the cerebral hemorrhage and control groups, included heatstroke cause, temperature, heart rate, respiratory rate, vasopressor use, mechanical ventilation use, Acute Physiology and Chronic Health Evaluation II, total bilirubin, creatinine, platelet count, prothrombin time, procalcitonin, creatine kinase, disseminated intravascular coagulation (DIC) occurrence, and DIC score. Multivariate logistic regression showed that heatstroke patients with higher DIC scores (odds ratio, 18.402, 95% confidence interval, 1.384-244.763, P = .027) and higher creatine kinase levels (odds ratio, 1.021, 95% confidence interval, 1.002-1.041, P = .033) were at a higher risk of developing ICH. The death rate was higher in the cerebral hemorrhage group than in the control group (P = .042). Heatstroke-related cerebral hemorrhage may be associated with elevated creatinine levels and DIC severity (International Society on Thrombosis and Hemostasis score) after heatstroke, and heatstroke with cerebral hemorrhage may accelerate death.

Abstract
To investigate the effects of a two-meals-a-day energy-restricted ketogenic diet (KD) on newly diagnosed obese patients with type 2 diabetes mellitus. In total, 60 obese patients with newly diagnosed type 2 diabetes mellitus were divided into 2 groups: 1 group followed a 2-meals-a-day KD and the other group followed a conventional diabetic diet. Changes in weight, blood glucose, blood lipids, insulin resistance, and uric acid levels were observed before and after 2 months of adhering to the respective diets under energy restriction. Both groups showed significant reductions in weight, waist circumference, body mass index, total cholesterol, triglycerides, high-density lipoproteins, low-density lipoproteins, fasting blood glucose, fasting insulin, and glycated hemoglobin (Pā
<ā
.05). The twice-daily KD group showed more significant improvements in these parameters compared to the conventional diabetic diet group. In addition, the 2-meals-a-day KD group showed a slight increase in uric acid levels compared to the conventional diabetic diet control group (Pā
<ā
.05). The 2-meals-a-day KD can significantly improve weight, blood glucose, and lipid control in newly diagnosed obese patients with type 2 diabetes mellitus.

Abstract
OBJECTIVE To measure free and total 25-hydroxyvitamin D [25(OH)D] immediately before embryo transfer and analyze its association with early pregnancy outcome parameters such as biochemical pregnancy, implantation rate, and clinical pregnancy rates in women undergoing fresh embryo transfer after their first ovarian hyperstimulation. DESIGN Prospective cohort study. SETTING Academically affiliated private fertility center. PATIENT(S): A total of 2,569 women undergoing fresh embryo transfer after ovarian hyperstimulation. INTERVENTIONS(S): None. MAIN OUTCOME MEASURE(S): The study end points were biochemical pregnancy rate, implantation rate, clinical pregnancy rate, ectopic pregnancy rate, early miscarriages, and ongoing pregnancy rate. Free and total 25(OH)D concentrations were measured 1 day before embryo transfer. RESULT(S): Total 25(OH)D correlated with free 25(OH)D. Total and free 25(OH)D serum concentrations were similar in those patients reaching and not reaching the study outcomes (biochemical pregnancy rate, implantation rate, clinical pregnancy rate, ectopic pregnancy rate, early miscarriages, and ongoing pregnancy rate). There was likewise no statistical difference when analyzing the frequency of all study outcomes in quintiles of either total or free 25(OH)D. In addition, the study population was divided into three groups according to the total vitamin D status based on clinical practice guideline. All outcomes were similar in women with adequate, insufficient, and deficient total 25(OH)D. Multiple linear regression analysis considering confounding likewise indicated no association of free or total vitamin D with any of the study outcomes. CONCLUSION(S): Neither free nor total 25(OH)D concentration at embryo transfer was associated with successful embryo implantation in women undergoing fresh transfer after ovarian hyperstimulation.
