This study provides a detailed approach to evaluating water quality in the Haridwar district, Uttarakhand, India, by integrating physicochemical and microbiological investigations. It employs multivariate analysis and applies water quality and trophic state indices to evaluate the current state of the water and identify potential sources of contamination. The results from the correlation matrix highlight the dynamic interactions between different water quality parameters.

Pediatric patients with sickle cell disease and vitamin D deficiency have worse clinical and laboratory outcomes. This study aims to quantify the prevalence of vitamin D deficiency in this population and identify possible risk factors for hypovitaminosis D by performing a cross-sectional study with children aged 3-18 years old with sickle cell disease. Sixty patients were evaluated, with a mean age of 10.

Electronic address:
To fully understand variation in phytoplankton community structure in the Eastern Indian Ocean (EIO), two research cruises were carried out during September-November 2020, and March-May 2021. The phytoplankton community in the EIO was mainly composed of cyanobacteria and diatoms in 2020, cyanobacteria in 2021. Trichodesmium thiebaultii was the dominant specie in both years.

Importance: Blood culture (BC) use benchmarks in US hospitals have not been defined.
Objective: To characterize BC use in adult intensive care units (ICUs) and wards in US hospitals.
Design, Setting, And Participants: A retrospective cross-sectional study of BC use in adult medical ICUs, medical-surgical ICUs, medical wards, and medical-surgical wards from acute care hospitals from the 4 US geographic regions was conducted.
Small mammals and associated infections in China: a systematic review and spatial modelling analysis.

Background: As natural reservoirs of diverse pathogens, small mammals are considered a key interface for guarding public health due to their wide geographic distribution, high density and frequent interaction with humans.
Methods: All formally recorded natural occurrences of small mammals (Order: Rodentia, Eulipotyphla, Lagomorpha, and Scandentia) and their associated microbial infections in China were searched in the English and Chinese literature spanning from 1950 to 2021 and geolocated. Machine learning models were applied to determine ecological drivers for the distributions of 45 major small mammal species and two common rodent-borne diseases (RBDs), and model-predicted potential risk locations were mapped.
