Metabolic and Orexin-A Responses to Ketogenic Diet and Intermittent Fasting: A 12-Month Randomized Trial in Adults with Obesity
CONCLUSIONS: The ketogenic diet was associated with the most pronounced long-term metabolic improvements, whereas 16:8 time-restricted eating yielded faster early responses and the most stable enhancement in Orexin-A levels. These findings indicate distinct metabolic and neuroendocrine adaptation profiles across dietary strategies. Given the small sample size, results should be interpreted cautiously, and larger trials are…

Effect of melatonin versus placebo for the prevention of delirium among medically hospitalised older patients: a double-blinded randomised controlled trial (project RESTORE)
CONCLUSIONS: In this trial, melatonin did not significantly reduce the incidence of delirium. The lower-than-expected numbers of outcome events and resultant early termination for futility limited the study’s power. As a result, the study findings should be interpreted with caution, and further research is necessary before definitive recommendations can be made.

Therapeutic Effects of a WeChat Mini-Program on Metabolic Dysfunction-Associated Fatty Liver Disease: Randomized Controlled Trial
CONCLUSIONS: Readily scalable in primary care and varied-resource settings, our WeChat mini-program-based intervention extends beyond weight loss to reduce hepatic steatosis and improve metabolic parameters, thereby addressing the critical gap in targeted MAFLD management in China with a low-cost model for high-burden populations. Nevertheless, larger future studies are needed to confirm these findings with greater…

The efficacy of freehand, pilot drilled and fully guided implant surgery in partially edentulous patients: A randomized control trial
CONCLUSION: Fully guided implant surgery outperformed other techniques in accuracy, efficiency, and patient satisfaction. These findings support fully guided, prosthetically driven workflows as a preferred option for partially edentulous patients, particularly in cases requiring high precision.

Interdisciplinary collaborative teaching in vascular surgery training: A randomized trial of radiologist-surgeon partnership in China
This randomized controlled trial evaluates an innovative interdisciplinary teaching model co-led by radiologists and vascular surgeons within China’s standardized residency training program. Forty trainees were randomized into two groups: one receiving collaborative teaching, which included joint lectures, radiologist-attended ward rounds, and interdisciplinary case conferences; and the other undergoing traditional vascular single-discipline training. The experimental group…

Phosphatidylethanol as an objective measure of heavy drinking days in a clinical trial for alcohol use disorder
CONCLUSIONS: Our findings support the use of PEth as an objective measure of heavy drinking days in a clinical setting. Further research is needed to validate these findings in larger cohorts.

Effect of irrigation solution temperature during pars plana vitrectomy on early postoperative choroidal vascularity
CONCLUSION: PPV caused an early postoperative decrease in choroidal perfusion, which was significant in the cold irrigation group. However, there was no significant difference between cooled and room-temperature irrigation solutions.

Audiological profile for assessment of sensorineural hearing loss in treatment naïve chronic myeloid leukemia: impact of early TKI treatment on reversibility
Sensorineural hearing loss (SNHL) is an underrecognized manifestation in chronic myeloid leukemia (CML), particularly in the setting of hyperleukocytosis. Its prevalence, pathophysiology, and response to tyrosine kinase inhibitor (TKI) therapy remain poorly characterized. To assess the prevalence, severity, and reversibility of SNHL in treatment-naïve CML patients and evaluate associations with leukocyte count and disease risk.…

Impact of Patient-Controlled Bag Squeeze on Pain and Anxiety in Male Patients Undergoing Flexible Cystoscopy: A Double-Blind Randomized Control Study
CONCLUSIONS: Patient-controlled bag squeeze appears to be a safe and effective analgesia method comparable to caregiver-assisted methods, and demonstrates favorable patient preference.

Comparison of cognitive workload between very short answer questions and multiple-choice questions: an eye-tracking experiment
Very short answer questions (VSAQs) have gained attention for their superior psychometric properties compared to multiple-choice questions (MCQs). While VSAQs require knowledge recall, MCQs primarily involve knowledge recognition. This difference in cognitive processes may lead to varying cognitive workloads, defined as the amount of mental processing in working memory. Previous studies have not demonstrated consistent…
