Boosting ensemble techniques are commonly employed for forecasting Type-II diabetes mellitus. Light Gradient Boosting Machine (LightGBM) is a widely used algorithm known for its leaf growth strategy, loss reduction, and enhanced training precision. However, LightGBM is prone to overfitting. In contrast, CatBoost utilizes balanced base predictors known as decision tables, which mitigate overfitting risks and significantly improve testing time efficiency. CatBoost’s algorithm structure counteracts gradient boosting biases and incorporates an overfitting detector to stop training early. This study focuses on developing a hybrid model that combines LightGBM and CatBoost to minimize overfitting and improve accuracy by reducing variance. For the purpose of finding the best hyperparameters to use with the underlying learners, the Bayesian hyperparameter optimization method is used. By fine-tuning the regularization parameter values, the hybrid model effectively reduces variance (overfitting). Comparative evaluation against LightGBM, CatBoost, XGBoost, Decision Tree, Random Forest, AdaBoost, and GBM algorithms demonstrates that the hybrid model has the best F1-score (99.37%), recall (99.25%), and accuracy (99.37%). Consequently, the proposed framework holds promise for early diabetes prediction in the healthcare industry and exhibits potential applicability to other datasets sharing similarities with diabetes.展开更多

In subsaharian countries;there is a lack of knowledge considering relation between category of weight and threshold maximum oxidation of lipids. Objectives: The main objectives of this study were to analyze the effect of category of weight on lipoxmax and to identify the zones of target intensities corresponding to lipoxmax. Materials and Methods:Twenty four male well-training judoists, divided in two groups according to weight, were evaluated during calorimetry effort’ test. For this situation, cardiorespiratory parameters (HR, VO2, VO2max), blood parameter (lactatemia), anthropometric variables and zones of target corresponding to lipox were evaluated. For statistical analysis, Shapiro-Wilks test was used to compare all the data and differences were confirmed by one-way variance. Results: No significant differences were observed among two groups for target intensities to lipox. The judoists of group 1 were aged to 24.1 ± 5.9 years with 1.78 ± 0.07 m versus 20.4 ± 1.6 years with 1.86 ± 0.04 m. Primary results indicated higher intensities for lipoxmax. Also, values of power (% LDC) and VO2 and were significantly higher in the judoists for group 2, with respectively: 45.3 ± 10.2 and 46.4 ± 8.6 ml/min versus 38.2 ± 7.2 and 31.3 ± 7.6 ml/min. Conclusion: High weight in judoists induces high intensities of lipoxmax and change oxidation of lipids markers following training.展开更多

Methods: The clinical records of 1599 spine surgery pa-tients counted from 2008-2009 were reviewed. The largest groups of patients belonged to MS-DRG 460 (N = 585) and to MS-DRG 473 (N = 700). These two MS-DRG patient groups were used as the study cohort representing patients who, by definition, did not have serious comor-bidities or complications. Results: Unemployed non-cervical patients tended to stay on average 1.8 days longer in hospital and had on average $5800 higher hospital charges. No major differ-ences were noted in length of stay and hospital cost between government and private insurance patients. However, self-pay non-cervical fusion patients had notable increases in length of stay and hospital cost, especially in the >39 and <60 age group with the difference in length of stay amounting to 5 days and in hospital charges to $10,000. Univariate analysis with DRG (460 or 473) as a covariate showed significant impact from employment status on length of stay (F = 4.259, P = 0.014) and less significant impact from payor category on hospital charges (F = 2.229, P = 0.064) in the economically-productive 40 -59 age group. Conclusions: In general, no increase in hospital resource consumption was noted except among self-pay patients, the same group seemingly least able to afford expensive healthcare.展开更多
