Data sources are achieved records of men workers' passbooks and registry for work permits in two rural parts of Southern France. We obtained three samples: masons from Rancon, a Limousin village, local sedentary alpine workers and Italian immigrants. The results obtained provide two types of information. The first concerns adult height, which is thought to be a result of both a growth pattern and environmental factors. The second concerns growth rates at the end of adolescence. The results seem to contradict the statements made above concerning the relationships between misery, elevation and height. While the alpine inhabitants are shorter, the Limousin inhabitants are taller in sprite they live in a miserable environment. It appears that taller individuals select themselves into migration. Thus, this model would contradict the idea of a regional genetic base.

Background: There are few studies examining the physical developmental phenotypes of nutritional deficiency diseases (NDDs) among Chinese children aged 1-7 years by anthropometrics and clarifying the specific NDD categories that caused growth faltering.
Methods: A total of 3054 cases of NDDs in children aged 1-7 years were investigated. The age, height, and weight of children with NDDs were adjusted by using the skewness coefficient-median-coefficient of variation method, and the results were compared with the WHO standardized level.

Background: Early childhood is a critical period for cognitive development, heavily influenced by nutrition. Despite significant economic advancements, malnutrition and micronutrient deficiencies persist in many low- and middle-income countries, including China, where dietary diversity remains suboptimal. Existing research predominantly relies on correlational data, underscoring the need for more rigorous empirical evidence.

Article Synopsis
- Advanced chronic kidney disease affects muscle health, making it important to find effective ways to assess muscle quality before kidney transplants.
- Musculoskeletal ultrasound, particularly measuring rectus femoris (RF) echogenicity, shows promise in identifying muscle weakness and quality issues in patients waiting for kidney transplants.
- In a study of 112 patients, a RF echogenicity cut-off of 70 demonstrated good sensitivity but moderate specificity for detecting quadriceps weakness, indicating an increased risk in patients with greater echogenicity.

Objective: To develop machine learning prediction models for small for gestational age with baseline characteristics and biochemical tests of various pregnancy stages individually and collectively and compare predictive performance.
Study Design: This retrospective study included singleton pregnancies with infants born between May 2018 and March 2023. Small for gestational age was defined as a birth weight below the 10th percentile according to the Intergrowth-21st fetal growth standards.
