Article Synopsis
- * The study measured iron intake, absorption, and overall gains in breastfed, formula-fed, and mixed-fed infants, showing significant differences in iron levels, particularly between breastfed and formula-fed babies.
- * The findings suggest that using isotope dilution techniques can effectively track how infants absorb iron over time and how their iron levels may drop in early infancy.
Article Synopsis
- The study examines how blood volume (BV) per kg of body mass (BM) may underestimate BV in individuals with high fat mass, particularly highlighting differences between sexes, ages, and fitness levels.* -
- It was found that women had a lower BV/BM compared to men by 25%, but when adjusted for lean body mass (LBM), women showed a 6% higher BV/LBM.* -
- Among athletes, BV/BM was 17.2% higher than non-athletes, but this difference shrank to only 2.5% when adjusted for LBM, indicating that LBM is a strong predictor of BV and hemoglobin mass (Hb) in clinical assessments.*
A comparative study of well-being, resilience, mindfulness, negative emotions, stress, and burnout among nurses after an online mind-body based intervention during the first COVID-19 pandemic crisis.
Front Psychol
March 2023
Background: To mitigate against the possible adverse effects of stress among nurses due to the COVID-19 outbreak, we designed a 12-week mind-body based online intervention program to promote well-being and prevent stress-related disorders such as burnout. Our study aimed to compare the impact of the intervention on perception of stress, negative emotions, burnout, mindfulness, resilience, and well-being at pretest and 6 months post-intervention and to compare the effect among nurses working at two different hospitals.
Methods: We conducted an uncontrolled trial using a convenience sample of nurses working at two hospitals in Mexico: one designated to treat confirmed COVID-19 patients (COVID-hospital) and the other whose patients had a negative COVID-19 test on admission (Non COVID-hospital).
Depressive symptoms among Mexican adolescent girls in relation to iron status, anaemia, body weight and pubertal status: results from a latent class analysis.
Public Health Nutr
February 2023
Objective: The study examined the association between depressive symptoms and iron status, anaemia, body weight and pubertal status among Mexican adolescent girls.
Design: In this cross-sectional study, depressive symptoms were assessed by the 6-item Kutcher Adolescent Depression Scale, and latent class analysis (LCA) was used to identify and characterise groups of girls based on depressive symptoms. Iron status and inflammation were assessed using ferritin and soluble transferrin receptor, C-reactive protein and alpha-1-acid glycoprotein, respectively.
Background: Inflammation during pregnancy may aggravate iron deficiency (ID) by increasing serum hepcidin and reducing iron absorption. This could restrict iron transfer to the fetus, increasing risk of infant ID and its adverse effects.
Objectives: We aimed to assess whether iron bioavailability and/or iron transfer to the fetus is impaired in overweight/obese (OW) pregnant women with adiposity-related inflammation, compared with normal-weight (NW) pregnant women.
