Randomized Controlled Trial Multicenter Study
Enteral administration of a simulated amniotic fluid in preventing feeding intolerance in very low birthweight neonates: A randomized controlled trial.
Feeding intolerance (FI) is a common finding in preterm neonates. Enteral administration of different forms of amniotic fluid (AF) has been tried for treating FI in high-risk neonates. Simulated amniotic fluid (SAF) is a solution with a similar electrolyte composition to human AF. The aim of this study was to examine whether enteral administration of SAF would improve feeding tolerance in very low birthweight (VLBW) neonates. ⋯ Results of the present study demonstrated that SAF solution might improve feeding tolerance in VLBW babies without evidence of its systemic absorption. Larger multicenter randomized studies are recommended.

Randomized Controlled Trial
Influence of food matrix delivery system on the bioavailability of vitamin D3: A randomized crossover trial in postmenopausal women.
Vitamin D insufficiency (blood 25-hydroxyvitamin D <50 nmol/L) is a global health problem. Vitamin D food fortification might be a solution, but knowledge is sparse on which food matrices yield the highest bioavailability. The aim of this study was to investigate the influence of different food matrices including complex formations with whey proteins on the human bioavailability of vitamin D. ⋯ The bioavailability of D3 was superior in milk and water compared with juice, regardless of whether WPI was added.

Randomized Controlled Trial
REsCue trial: Randomized controlled clinical trial with extended-release calcifediol in symptomatic COVID-19 outpatients.
This double-blind randomized controlled trial investigated raising serum 25-hydroxyvitamin D (25D) with extended-release calcifediol (ERC) on time to symptom resolution in patients with mild to moderate COVID-19. ⋯ ERC safely raised serum 25D to ≥50 ng/mL in outpatients with COVID-19, possibly accelerating resolution of respiratory symptoms and mitigating the risk for pneumonia. These findings warrant further study.

Randomized Controlled Trial
Gene-diet interaction in response to defatted flaxseed flour supplementation on obesity-related traits in Chinese overweight and obese adults: A randomized controlled trial.
Effects of dietary fiber on obesity-related traits in previous studies were inconsistent. The aim of the present study was to explore whether variants in genes related to satiety and appetite can modulate the effect of dietary fiber on obesity-related traits. Fifty-one overweight or obese adults were randomly allocated to two groups to consume control biscuits (n = 24) or biscuits containing defatted flaxseed flour (n = 27) at breakfast for 8 wk. ⋯ Compared with control biscuits, defatted flaxseed-flour biscuits significantly reduced body weight (P = 0.001) and body mass index (BMI) (P = 0.001) in A-allele carriers (AA + AT) of rs11076023 on the FTO gene but not in non-carriers (TT) (P for the interaction = 0.005 and 0.006) and decreased fasting serum glucose in participants with CC genotype (P = 0.019) but had less effect in T-allele carriers (TT + TC) (P = 0.021) of rs16147 on the NPY gene (P for the interaction = 0.002). Compared with the control biscuits, defatted flaxseed flour significantly reduced body weight (P < 0.001) in T-allele carriers (TT + TC) of rs155971 on the PCSK1 gene but not in non-carriers (CC) (P for the interaction = 0.041) and reduced body weight (P = 0.001) and BMI (P < 0.001) in A-allele carriers (AA + AG) of rs6265 on the BDNF gene but not non-carriers (GG) (P for the interaction = 0.017 and 0.018). Variants of genes related to satiety and appetite could modulate the effect of defatted flaxseed flour on obesity-related traits.
