Objective: Glucocorticoids (GCs) in breastmilk have previously been associated with infant body growth and body composition. However, the diurnal rhythm of breastmilk GCs was not taken into account, and we therefore aimed to assess the associations between breastmilk GC rhythmicity at 1 month and growth and body composition at 3 months in infants.

Methods: At 1 month postpartum, breastmilk GCs were collected over a 24-h period and analyzed by LC-MS/MS. Body composition was measured using air-displacement plethysmography at 3 months. Length and weight were collected at 1, 2, and 3 months.

Results: In total, 42 healthy mother-infant pairs were included. No associations were found between breastmilk GC rhythmicity (area-under-the-curve increase and ground, maximum, and delta) and infant growth trajectories or body composition (fat and fat free mass index, fat%) at 3 months.

Conclusions: This study did not find an association between breastmilk GC rhythmicity at 1 month and infant's growth or body composition at 3 months. Therefore, this study suggests that previous observations linking breastmilk cortisol to changes in infant weight might be flawed by the lack of serial cortisol measurements and detailed information on body composition.

Background: Acanthocephalans (thorny headed worms) of the genus Pseudoacanthocephalus mainly parasitize amphibians and reptiles across the globe. Some species of the genus Pseudoacanthocephalus also can accidentally infect human and cause human acanthocephaliasis. Current knowledge of the species composition of the genus Pseudoacanthocephalus from amphibians and reptiles in China is incomplete.

Background: Breast milk is a natural treasure for infants, and its microbiota contains a rich array of bacterial species. When breastfeeding is not possible, infant formula with probiotics can be used as a sole source or as a breast milk supplement. The main aim of this study was to evaluate the growth outcomes and tolerance of infants consuming an infant formula containing Bifidobacterium animalis ssp.

Although studies have examined the association of the Relative Fat Mass (RFM, a novel anthropometric index used as a surrogate for whole-body fat percentage) with all-cause mortality, the association of RFM with diabetes-related mortality and heart disease mortality has not been thoroughly investigated. In addition, no study has compared the associations of RFM and waist circumference (a surrogate for intra-abdominal fat) with cause-specific mortality and all-cause mortality. In the present study, we addressed these knowledge gaps.

Introduction: Older patients with cancer (65 years and older) are a growing population with unique nutrition-and treatment-related issues that accelerate aging. Nutrition interventions attenuate nutritional decline, muscle loss, and risk of malnutrition and sarcopenia in patients with cancer, however the evidence for older patients with cancer is limited. The aim of this systematic review was to evaluate the efficacy of nutrition interventions on nutritional status, body weight/composition and clinical outcomes in older patients with cancer and to identify future research priority areas.
