Among nursing home outbreaks of coronavirus disease 2019 (COVID-19) with ≥3 breakthrough infections when the predominant severe acute respiratory coronavirus virus 2 (SARS-CoV-2) variant circulating was the SARS-CoV-2 δ (delta) variant, fully vaccinated residents were 28% less likely to be infected than were unvaccinated residents. Once infected, they had approximately half the risk for all-cause hospitalization and all-cause death compared with unvaccinated infected residents.
Research uses of human bodies maintained by mechanical ventilation after being declared dead by neurological criteria (“heart-beating cadavers”), were first published in the early 1980s with a renewed interest in research on the newly or nearly dead occurring in about last decade. While this type of research may take many different forms, recent technologic advances in genomic sequencing along with high hopes for genomic medicine, have inspired interest in genomic research with the newly dead. For example, the Genotype-Tissue Expression (GTEx) program through the National Institutes of Health aims to collect large numbers of diverse human tissues with the eventual goal of elucidating the genetic bases of common diseases through a better understanding of the relationship between genetic variation and gene expression.
FFQ are popular instruments for assessing dietary intakes in epidemiological studies but have not been validated for use in severely obese pregnancy. The aim of the present study was to compare nutrient intakes assessed by an FFQ with those obtained from a food diary among severely obese pregnant women.
Comparison of an FFQ containing 170 food items and a food diary for 4 d (three weekdays and one weekend day); absolute agreement was assessed using the paired t test and relative agreement by Pearson/Spearman correlation, cross-classification into tertiles and weighted kappa values.
Antenatal metabolic clinic for severely obese women.
Thirty-one severely obese (BMI at booking ≥40·0 kg/m2) and thirty-two lean control (BMI = 20·0–24·9 kg/m2) pregnant women.
The findings showed that nutrient intakes estimated by the FFQ were significantly higher than those from the food diary; average correlation was 0·32 in obese and 0·43 in lean women. A mean of 48·5 % of obese and 47·3 % of lean women were correctly classified, while 12·9 % (obese) and 10·0 % (lean) were grossly misclassified. Weighted κ values ranged from −0·04 to 0·79 in obese women and from 0·16 to 0·78 in lean women.
Overall, the relative agreement between the FFQ and food diary was lower in the obese group than in the lean group, but was comparable with earlier studies conducted in pregnant women. The validity assessments suggest that the FFQ is a useful tool for ranking severely obese pregnant women according to the levels of their dietary intake.
