Objective: To assess the validity of recommendations for use of the 85th and 95th percentiles of body mass index (BMI) of the population in the United States of America as a screening tool to assess overweight/obesity in adolescents.
Methods: We investigated the relation between BMI and percent body fat in 1,540 adolescents (717 males and 823 females) aged 10 to 17.9 years old from a private high school in Niterói, a city in the state of Rio de Janeiro, Brazil. We used bioelectric impedance, with the appropriate equations for adolescents, to estimate percent body fat, which served as the gold standard (30% for girls and 25% for boys) to calculate the sensitivity and specificity of the 85th and 95th percentiles of the United States and Brazilian distribution curves of BMI.
Results: Sensitivity and specificity were high (above 80%) for the Niterói boys, except for the 85th percentile of the Brazilian curve (specificity = 61.8%) and for the 95th percentile of the United States curve (sensitivity = 55.4%). For the Niterói girls, the 85th- and 95th-percentile BMI cutoff points, from both the United States and Brazilian curves, showed low sensitivity, and that sensitivity decreased with age. Specificity was high for the girls, and much higher than it was for the boys.
Conclusions: These data suggest that using BMI to screen for overweight/obesity in adolescents can generate a high percentage of false-positives for Niterói boys and an even higher percentage of false-negatives for Niterói girls. A more universal approach to using anthropometric measures to screen for overweight/obesity should be developed, preferably linked to stages of maturation.

A Noncatalytic Cysteine Residue Modulates Cobalamin Reactivity in the Human B Processing Enzyme CblC.
Biochemistry

Laboratory of Clinical Biochemistry and Metabolism, Department of General Pediatrics, Adolescent Medicine and Neonatology, Faculty of Medicine, Medical Center, University of Freiburg, Freiburg im Breisgau 79106, Germany.
Human CblC catalyzes the indispensable processing of dietary vitamin B by the removal of its β-axial ligand and an either one- or two-electron reduction of its cobalt center to yield cob(II)alamin and cob(I)alamin, respectively. Human CblC possesses five cysteine residues of an unknown function. We hypothesized that Cys149, conserved in mammals, tunes the CblC reactivity.

Poisoning by organophosphate (OP) nerve agents remains a pressing global threat due to their extensive use in chemical warfare agents and pesticides, potentially causing high morbidity and mortality worldwide. This urgent need for effective countermeasures has driven considerable interest in innovative detoxification approaches. Among these, nanoparticle technology stands out for its multifunctional potential and wide-ranging applications.

Indiana State Department of Corrections, USA.
In the United States, the COVID-19 Pandemic caused many autistic adults to be fearful and worried about their health. There is a lot of research that says that when autistic adults experience health distress it can worsen their mental health. We do not know, however, what might explain how experiencing health distress negatively affects mental health.

Prior research has shown that the death of a baby (whether it be through miscarriage, stillbirth, or infant loss) can have profound effects on the parents involved. However, research has yet to adequately understand how these effects differ cross-culturally. Our research addresses these issues through a qualitative study of 47 bereaved mothers in the United States and New Zealand-cultures that have differing perspectives on death.

Background: The World Health Organization conditionally recommends reactive drug administration to reduce malaria transmission in settings approaching elimination. However, few studies have evaluated the impact of reactive focal drug administration (rFDA) in sub-Saharan Africa, and none have evaluated it under programmatic conditions. In 2016, Senegal's national malaria control programme introduced rFDA, the presumptive treatment of compound members of a person with confirmed malaria, and reactive mass focal drug administration (rMFDA), an expanded effort including neighbouring compounds during an outbreak, in 10 low transmission districts in the north of the country.
