Predictive equation derived from 6,497 doubly labelled water measurements enables the detection of erroneous self-reported energy intake.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

Specialty palliative care use among cancer patients: A population-based study.

Background: Rigorous population-based assessments of the use of specialty palliative care (SPC) in the US are rare.

Settings/subjects: This study examined SPC use among cancer patients in a mid-sized metropolitan area in Southeast US.

Measurements: In this cancer decedent cohort study, data were acquired and linked from the state-wide cancer registry; state-wide hospital discharge dataset; and local SPC providers.

Prevalence of functional defecation disorders in European children: A systematic review and meta-analysis.

Objectives: Functional defecation disorders (FDDs) are common among children worldwide. The prevalence of these disorders has not been clearly described in Europe. This study performed a systematic review and meta-analysis on the prevalence of FDD in European children and assessed geographical, age, and sex distribution and associated factors.

APOBEC3A deaminates CTG hairpin loops to promote fragility and instability of expanded CAG/CTG repeats.

CAG/CTG repeats are prone to expansion, causing several inherited human diseases. The initiating sources of DNA damage which lead to inaccurate repair of the repeat tract to cause expansions are not fully understood. Expansion-prone CAG/CTG repeats are actively transcribed and prone to forming stable R-loops with hairpin structures forming on the displaced single-stranded DNA (S-loops).

The SARS-CoV-2 test scale-up in the USA: an analysis of the number of tests produced and used over time and their modelled impact on the COVID-19 pandemic.

Background: Rapid, accessible, and accurate testing was paramount to an effective US COVID-19 response. Federal partners supported SARS-CoV-2 testing scale-up through an interagency-coordinated approach that focused on expanding supply chains, research and development, validation, and improving patient access. We aimed to provide an overview of the federal efforts to scale up the testing response and study the impact of scale-up.
