AI Article Synopsis
- The study aimed to determine normal nasal nitric oxide levels in Chinese children aged 6-18 to aid clinical diagnosis.
- A total of 2,580 children from 12 centers in China were tested, measuring both nitric oxide levels and physical characteristics like height and weight.
- The findings revealed that the average nasal nitric oxide level was 454.5 ppb, with significant predictors being age and sex, providing a reference for future clinical assessments.
Article Abstract
Objectives: To obtain the normal values of fractional concentration of nasal nitric oxide in Chinese children aged 6-18 years, so as to provide reference for clinical diagnosis.
Methods: 2,580 out of 3,200 children (1,359 males and 1,221 females), whom were included from 12 centers around China were taken tests, their height and weight were also recorded. Data were used to analyze the normal range and influencing factors of fractional concentration of nasal nitric oxide values.
Measurements: Data was measured using the Nano Coulomb Breath Analyzer (Sunvou-CA2122, Wuxi, China), according to the American Thoracic Society/European Respiratory Society (ATS/ERS) recommendations.
Main Results: We calculated the normal range and prediction equation of fractional concentration of nasal nitric oxide values in Chinese children aged 6-18 years. The mean FnNO values of Chinese aged 6-18 yrs was 454.5 ± 176.2 ppb, and 95% of them were in the range of 134.5-844.0 ppb. The prediction rule of FnNO values for Chinese children aged 6-11 yrs was: FnNO = 298.881 + 17.974 × age. And for children aged 12-18 yrs was: FnNO = 579.222-30.332 × (male = 0, female = 1)-5.503 × age.
Conclusions: Sex and age were two significant predictors of FnNO values for Chinese children(aged 12-18 yrs). Hopefully this study can provide some reference value for clinical diagnosis in children.

Prospective associations of adolescent obesity phenotypes with self-reported polycystic ovary syndrome diagnosis in young adulthood.
Hum Reprod

Department of Epidemiology, Brown University School of Public Health, Providence, RI, USA.
Study Question: Are empirically derived adolescent overweight/obesity phenotypes differentially associated with polycystic ovary syndrome (PCOS) in young adulthood?
Summary Answer: Self-reported PCOS diagnosis risk in young adulthood varied by empirically derived adolescent overweight/obesity phenotypes, with the highest risk observed among those in the 'mothers with obesity' and 'early puberty' phenotypes.
What Is Known Already: Overweight and obesity during puberty are postulated to promote the development of PCOS. Much of the prior literature in this area is cross-sectional and defines weight status based solely on BMI, yet emerging research suggests that not all people with overweight/obesity have the same risk for chronic health conditions, including PCOS.
Prevalence, intensity and risk factors of soil-transmitted helminthiasis after five effective rounds of preventive chemotherapy across three implementation units in Ondo State, Nigeria.

Background: Routine epidemiological data are essential for monitoring the effectiveness of preventive chemotherapy (PC), optimizing resource allocation, and addressing the evolving needs in the elimination of soil-transmitted helminthiasis (STH). This study assesses the prevalence, intensity, and associated risk factors of STH following five rounds of albendazole-based PC in three implementation units (IUs) in Ondo State, Nigeria.
Methodology: Fresh stool samples were collected from 2,093 children aged 5-14 years across 45 systematically selected schools in three IUs: Ese-Odo, Irele, and Ile-Oluji.
Revising the definition of "demand satisfied for modern methods of family planning:" A cross-sectional study to explore incorporating person-centered constructs of demand, choice, and satisfaction.

Guttmacher Institute, New York, New York, United States of America.
Several challenges to validity have been identified with standard approaches used to measure "demand satisfied for modern methods of family planning." This study explored construct validity of the widely used indicator for "demand satisfied" by comparing the standard definition to alternative definitions of the indicator highlighting dimensions of women's own perceived demand, choice, and satisfaction. This cross-sectional study of women aged 15-49 years was conducted in Argentina (n = 1492), Ghana (n = 1600), and India (n = 1702) using a two-staged random sampling design.

Purpose: The aim was to determine and compare the short-term effects of two intensive semi-occluded vocal tract (SOVT) programs, "straw phonation" (SP) and "resonant voice therapy" (RVT), on the phonation of children with vocal fold nodules.
Method: A pretest-posttest randomized controlled study design was used. Thirty children aged 6-12 years were randomly assigned to the SP group ( = 11), RVT group ( = 11), or control group receiving indirect treatment ( = 8) for their voice problems.
