Achievements, Challenges, and Future Direction in Early Life Nutrition.

Nestle Nutr Inst Workshop Ser

November 2024

Head of Metabolic Health Department, Nestlé Institute of Health Sciences, Nestlé Research, Société des Produits Nestlé S.A., Lausanne, Switzerland.

Malnutrition is present in most countries of the world. This ranges from general undernutrition due to insufficient food, or poor-quality diets low in some essential nutrients, to overnutrition and obesity with energy-rich but nutrient-poor diets. The fundamental aim of dietary recommendations is to prevent deficiency diseases, and the assumptions which underpin these recommendations need to be understood when considering what advice to give to the general public or individual patients.

Background: The breast neuroendocrine neoplasms (NENs) represent a heterogeneous group of tumors and account for less than 1% of all NENs. The 5th edition of the WHO Classification of Breast Tumors in 2019 introduced a more stringent definition for breast NENs including neuroendocrine tumors (NETs) (G1, G2) and neuroendocrine carcinomas (NECs) (small cell carcinoma, large cell neuroendocrine carcinoma). While the diagnostic criteria and treatment of breast NENs still have some unsolved issues.

Article Synopsis
  • Carriers of BRCA1/2 pathogenic variants were studied to determine their risk of developing cancers during childhood, adolescence, and young adulthood (CAYA).
  • Analysis of data from over 47,000 individuals revealed that while young women with BRCA1/2 mutations had a significantly increased risk of breast cancer in their 20s, no increased risk was found for other types of CAYA cancers.
  • The study concluded that there's little evidence to support routine genetic testing for children of BRCA1/2 carriers or for young cancer patients, as the overall cancer risk appears low aside from breast cancer in young women.

Article Synopsis
  • The study examines how aging affects cerebral blood flow (CBF) in older adults by investigating changes in brain structure and partial volume effects due to brain atrophy.
  • Findings show that while there is a general decline in global gray-matter CBF as people age, some specific brain regions may actually experience increases in CBF after correcting for partial volume effects.
  • The results highlight that although age-related reductions in CBF are evident, regional differences in blood flow are more accurately captured when accounting for partial volume effects in brain imaging.
