The predictive value of resting heart rate in identifying undiagnosed diabetes in Korean adults: Korea National Health and Nutrition Examination Survey / 한국역학회지

OBJECTIVES@#The purpose of this study was (1) to examine whether the addition of resting heart rate (RHR) to the existing undiagnosed diabetes mellitus (UnDM) prediction model would improve predictability, and (2) to develop and validate UnDM prediction models by using only easily assessable variables such as gender, RHR, age, and waist circumference (WC). @*METHODS@#Korea National Health and Nutrition Examination Survey (KNHANES) 2010, 2012, 2014, 2016 data were used to develop the model (model building set, n=19,675), while the data from 2011, 2013, 2015, 2017 were used to validate the model (validation set, n=19,917). UnDM was defined as a fasting glucose level ≥126 mg/dL or glycated hemoglobin ≥6.5%; however, doctors have not diagnosed it. Statistical package for the social sciences logistic regression analysis was used to determine the predictors of UnDM. @*RESULTS@#RHR, age, and WC were associated with UnDM. When RHR was added to the existing model, sensitivity was reduced (86 vs. 73%), specificity was increased (49 vs. 65%), and a higher Youden index (35 vs. 38) was expressed. When only gender, RHR, age, and WC were used in the model, a sensitivity, specificity, and Youden index of 70%, 67%, and 37, respectively, were observed. @*CONCLUSIONS@#Adding RHR to the existing UnDM prediction model improved specificity and the Youden index. Furthermore, when the prediction model only used gender, RHR, age, and WC, the outcomes were not inferior to those of the existing prediction model.

A Case of Infantile Fungal Urinary Tract Infection

Urinary tract infection is common in the pediatric population. The most common causative agents are bacteria, among which Escherichia coli is the most frequent uropathogen. Although fungal urinary tract infection is rare in the healthy pediatric population, it is relatively common among hospitalized patients. Fungus may be isolated from the urine of immunocompromised patients or that of patients with indwelling catheters. The most common cause of funguria is Candida albicans. Although more than 50% of Candida isolates belong to non-albicans Candida , the prevalence of non-albicans candiduria is increasing. Herein, we report a case of community-acquired candiduria in a 4-month-old immunocompetent male infant who had bilateral vesicoureteral reflux and was administered antibiotic prophylaxis. He was diagnosed with urinary tract infection caused by Candida lusitaniae and was managed with fluconazole.

The Effect of Post-operative Exercise in Colorectal Cancer Patients: A Pilot Randomized Controlled Trial (RCT) Study

PURPOSE: The purpose of this study was to examine the effect of post-operative exercise on body composition, psychological factors, time to flatus and length of hospital stay in stage 1~3 colorectal cancer patients. METHODS: A total of 35 post surgery patients were recruited and randomly assigned to the exercise or controlled group. Participants in the exercise group exercised twice a day while participants in the control group followed the clinical pathways (CP). RESULTS: A total of 25 participants completed the trial. Post-operative exercise resulted in a clinically meaningful, but statistically insignificant reduction in body weight (Exercise: -1.10±1.63 kg vs. CP: -0.63±1.16 kg; p=.111), fat mass (Exercise: -1.43±0.95 kg vs. CP: 0.64±4.29 kg; p=.100). When participants' body composition were compared to their baseline values at the baseline, only the exercise group experienced a significant reduction in body weight, body mass index (BMI) and fat mass. In addition, post-operative exercise significantly improved health related quality of life (Exercise: 2.27±2.08 vs CP: -12.82±22.47; p=.008). However, there was no difference in time to flatus and the length of hospital stay between groups. CONCLUSION: The current pilot study suggests that the post-operative exercise program was safe and produced for health related quality of life improvements in colorectal cancer patients.
