Vitamin D deficiency in a pediatric population with sickle cell disease.

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.

Behavioral and Electrophysiological Assessment of Central Auditory Processing in Individuals with Sickle Cell Disease.

Introduction: Sickle cell anemia has a genetic origin characterized by an autosomal recessive inheritance pattern. The nervous system may be subject to vaso-occlusion and, consequently, affect the proper functioning of the central portion of hearing.

Objective: To assess central auditory skills and analyze short- and long-latency auditory evoked potentials in children with sickle cell disease.

Scorpionism in the State of Bahia, Brazil: A More Neglected Problem During the Pandemic?

Introduction: During the confinement in the COVID-19 pandemic, there was an increase in the production of urban waste, increasing the risk of accidents caused by scorpions. We sought to determine the clinical and epidemiologic aspects of scorpionism records in the 7 mesoregions of the State of Bahia, Brazil, examining differences in periods before and during the pandemic.

Methods: Data were obtained from SINAN, Brazil's Notifiable Diseases Information System (January 2010-December 2021).

Divergent otolithic systems in the inner ear of Paranthropus robustus and Australopithecus africanus.

The bony labyrinth of the inner ear houses the sensory end-organs responsible for balance (otolithic system in the utricle and saccule, and semicircular canal system) and hearing (cochlea). Study of the bony labyrinth has revealed considerable morphological diversity in the hominin lineage (semicircular canals and cochleae) and aided in reconstructing essential aspects of primate evolution, including positional behavior, audition, and phylogenic affinities. However, evidence of evolutionary change in the hominin otolithic system remains elusive.

Molecular Diagnosis of the Main Hemoparasites of Dairy Cows in the State of Ceará.

Background/objectives: Trypanosomiasis and bovine babesiosis correspond to important diseases that cause great economic losses, but there are still no studies evaluating their occurrence in herds of dairy cattle in Ceará. The aim of this study was to perform molecular diagnosis of the main hemoparasites of dairy cows in the microregion of the central hinterland of Ceará.

Methods: For the molecular diagnosis of parasites, genomic material was extracted and polymerase chain reaction directed to the cdCatL-like gene for and SS rRNA of and was performed.
