Risk factors for hazardous drinking in university students from South Africa and Belgium: a cross-cultural comparison study.
Previous studies have associated certain risk factors with hazardous drinking in students. However, big cultural and geographical differences exist regarding alcohol use. ⋯ This study found a significant difference in hazardous drinking between Belgian and South African university students.

Relationship of oxidative stress and antioxidant response with vaso-occlusive crisis in sickle cell anaemia.
Though sickle cell anaemia (SCA) is known to promote oxidative stress, there is paucity of information on the relationship between oxidative stress and vaso-occlusive crisis (VOC). ⋯ Sickle cell anaemia exhibited oxidative stress and alteration in the levels of antioxidant indices which was possibly associated with vaso-occlusive crisis.

Prevalence of lower urinary tract symptoms in nurses and civil servants working at a hospital: a cross-sectional study.
Lower urinary tract symptoms (LUTS) are common in women and can interrupt daily living activities of the individuals. The study aimed at determining the LUTS prevalence and the influencing factors in nurses and civil servants working at a hospital. ⋯ Workplace conditions of the health workers should be reorganizing to have healthy urinary habits for preventing them from the development of LUTS.

COVID-19 mortality rate prediction for India using statistical neural networks and gaussian process regression model.
The primary purpose of this research is to identify the best COVID-19 mortality model for India using regression models and is to estimate the future COVID-19 mortality rate for India. Specifically, Statistical Neural Networks (Radial Basis Function Neural Network (RBFNN), Generalized Regression Neural Network (GRNN)), and Gaussian Process Regression (GPR) are applied to develop the COVID-19 Mortality Rate Prediction (MRP) model for India. ⋯ Here, sigma (σ) is a hyperparameter whose value is used to constrain the learning process of the above models with minimum Root Mean Squared Error (RMSE). The performance of the models is evaluated using the RMSE and 'R2 values, which shows that the GRP model performs better than the GRNN and RBFNN.

Visual function, spectacle independence, and patients' satisfaction after cataract surgery- a study in the Central Region of Ghana.
Reduced visual function is associated with diminished quality of life as well as decreased physical and mental health. Poor visual function related to cataracts is also a risk factor for falls and traffic accidents, which may lead to hospital admissions and limit independence. ⋯ Satisfaction of patients after cataract surgery was high but was greatly influenced by visual functions with contrast sensitivity being a better predictor of satisfaction than visual acuity and stereopsis. Spectacle independence after cataract surgery was low at distance and extremely low at near. The type of cataract surgery performed influenced thespectacle independence.
