Abstract

Childhood obesity is a medical and social problem in Japan. The number of obese children has been increasing steadily since 1980 according to a survey on school health statistics. However, more simple and reliable criteria for assessment of obesity in children are required. The aim of this study was to establish gender- and age-specific body mass index (BMI) cutoff values for evaluation of obesity in school-aged children. A total of 100,587 elementary school, junior and senior high school students, aged 6 to 17 years, comprised the study population, in whom BMI was measured. The BMI cutoff values were calculated by using the receiver operating characteristic (ROC) analysis in the degree of obesity of 20% or greater as definition of obesity. The validity of the determined cutoff values of BMI was then compared with the Rohrer index, the International Obesity Task Force (IOTF) data and the percentile method. The sensitivity and specificity of the BMI cutoff values were over 93% in both boys and girls of all ages, thereby providing criteria that are highly diagnostic in all ages. The Rohrer Index and BMI 95th percentile values tended to underestimate obesity, while the IOTF criteria tended to overestimate it. In conclusion, the BM...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
