Objective: Dyslipidaemia, which is now seen as one of the most important cardiovascular risk factors, is becoming more common in the younger population. The aim of this study was to assess the efficacy of tracking serum lipid levels over a four-year period in an urban population of schoolchildren.
Methods: The study began in 1999 with a cohort of 789 schoolchildren. Four years later this group was resurveyed and a further 452 adolescent were recruited to the study.
Results: The percentages of boys who were initially in the extreme quartile for total cholesterol (TC), low-density lipoprotein (LDL) cholesterol and triglycerides were 42.5, 54.8 and 40.4%, respectively. Similarly, the percentages of girls in the extreme quartile were 62.7, 53.8 and 38.2%. Four years later, both the boys and girls were still in the extreme quartile for these parameters. Therefore, the best predictor of followup level for each of the serum lipoprotein cholesterol fractions was the corresponding baseline level. Interestingly, the next best predictor in most of the groups was change in body mass index (DeltaBMI) and smoking status.
Conclusion: Prevention of coronary heart diseases in adults must begin early on in childhood, and should be driven by health education towards achieving a healthy lifestyle.

Extensive research work has been done for the estimation of population mean using bivariate auxiliary information based on conventional measures. Conventional measures of the auxiliary variables provide suspicious results in the presence of outliers/extreme values. However, non-conventional measures of the auxiliary variables include quartile deviation, mid-range, inter-quartile range, quartile average, tri-mean, Hodge-Lehmann estimator etc.

The Indian coast has been experiencing an increase in algal bloom events over the decades. Owing to the regional and seasonal dynamics of algal biomass (proxy: chlorophyll-a, hereafter chl-a), a multitude of thresholds of chl-a has been defined for different parts of the global seas to determine algal bloom conditions. However, no such clear definition is given for the Indian coastal waters.

A convenient but efficient tool for evaluating dietary intakes in Chinese professional athletes has yet to be established. The aim of this study was to assess the validity of a short semi-quantitative food frequency questionnaire (FFQ) through comparison with 3-day weighed food records (3DWFRs) and corresponding serum biomarkers from a cohort of 102 professional athletes, while also evaluating its reproducibility. The relative validity was assessed using Spearman correlation coefficients, cross-quintiles classification, weighted kappa, and Bland-Altman analysis, while reproducibility was evaluated using the Spearman correlation coefficients and intraclass correlation coefficient (ICC) between two FFQs.

Accurately predicting individual antidepressant treatment response could expedite the lengthy trial-and-error process of finding an effective treatment for major depressive disorder (MDD). We tested and compared machine learning-based methods that predict individual-level pharmacotherapeutic treatment response using cortical morphometry from multisite longitudinal cohorts. We conducted an international analysis of pooled data from six sites of the ENIGMA-MDD consortium (n = 262 MDD patients; age = 36.

Objective: This study was to explore the factors associated with prolonged hospital length of stay (LOS) in patients with intracranial aneurysms (IAs) undergoing endovascular interventional embolization and construct prediction model machine learning algorithms.
Methods: Employing a retrospective cohort study design, this study collected patients with ruptured IA who received endovascular treatment at Jingzhou First People's Hospital during the inclusion period from September 2022 to December 2023. The entire dataset was randomly split into training and testing dataset with a 7:3 ratio.
