AI Article Synopsis

  • The study followed 43 adults with classical phenylketonuria (PKU) identified through neonatal screening and treated with a phenylalanine-restricted diet.
  • Among the group, 19 individuals continued the diet while 24 stopped by the average age of 7.8 years.
  • At an average follow-up age of 22, those who maintained the diet showed significantly better social and academic outcomes compared to those who discontinued it.

Article Abstract

Forty-three adults with classical phenylketonuria were identified by neonatal screening and treated with a phenylalanine (Phe) restricted diet. Nineteen have remained on dietary treatment with varying levels of blood Phe control and 24 have discontinued the diet at an average age of 7.8 years. Follow up at an average age of 22 years revealed that the cohort remaining on dietary treatment have achieved substantially better social and academic achievement than the 24 who discontinued dietary treatment. Another group of 19 adults who were not diagnosed until an average age of 2.5 years have also been evaluated after an average of 22 years on a Phe restricted diet. This report is based upon Wechsler Adult Intelligence Revised Test scores, attendance at college, employment and marital status.

Introduction: Food insecurity is the condition of limited access to healthy and safe food. Malnutrition resulting from food insecurity is a concern particularly in the surgical population due to the association with impaired healing. This aim of this study was to report the incidence and risk factors for food insecurity in the orthopaedic trauma population.

Unlabelled: Many animals contain a species-rich and diverse gut microbiota that likely contributes to several host-supportive services that include diet processing and nutrient provisioning. Loss of microbiome taxa and their associated metabolic functions as result of perturbations may result in loss of microbiome-level services and reduction of metabolic capacity. If metabolic functions are shared by multiple taxa (i.

Background: Precision nutrition-based methods develop tailored interventions and/or recommendations accounting for determinants of intra- and inter-individual variation in response to the same diet, compared to current 'one-size-fits-all' population-level approaches. Determinants may include genetics, current dietary habits and eating patterns, circadian rhythms, health status, gut microbiome, socioeconomic and psychosocial characteristics, and physical activity. ​​​​In this systematic review, we examined the evidence base for the effect of interventions based on precision nutrition approaches on overweight and obesity in children and adolescents to help inform future research and global guidelines.

Puerarin Attenuates Podocyte Damage in Mice With Diabetic Kidney Disease by Modulating the AMPK/Nrf2 Pathway.

Nephrology Department, Jiangxi Provincial Key Research Laboratory of Traditional Chinese Medicine, Key Research Laboratory of Chronic Renal Failure, Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine, Nanchang, Jiangxi 330006, China.

This study aimed to investigate the potential mechanisms of puerarin in alleviating diabetic nephropathy (DKD) in mice. The DKD model was induced by multiple low-dose injections of streptozotocin (STZ) and a high-sugar and high-fat diet in male C57BL/6J mice. After confirming the onset of DKD, mice were given irbesartan, distilled water, or different concentrations of puerarin (40 and 80 mg/kg/d) by gavage for 8 weeks.
