Maternal perinatal anxiety and infant primary care use in 1998-2016: a UK cohort study.

Background: There is some evidence that perinatal anxiety (PNA) is associated with lower rates of infant vaccinations and decreased access to preventative infant healthcare, but results across studies have not been conclusive.

Objective: To investigate the relationship between maternal PNA and infant primary care use.

Methods: Cohort study of mother-infant pairs identified between 1998 and 2016 using IQVIA Medical Research Database (IMRD).

Trial of alginates in throat symptoms: protocol for a pragmatic, multicentre, placebo controlled, double blind, parallel, randomised controlled trial of liquid alginate (Gaviscon Advance) for the treatment of persistent throat symptoms.

Introduction: Persistent throat symptoms (PTS) are indicators for over 60 000 new patient referrals to NHS secondary care annually. PTS have been attributed to manifestation of gastro-oesophageal reflux disease (GORD) with the hypothesis that gastric refluxate damages and irritates the mucosa of the upper aerodigestive tract. Symptoms of PTS and GORD are commonly treated with proton pump inhibitors (PPIs) or alginates are often, incorrectly, advocated.

Genetic Test Utilization and Cost among Families of Children Evaluated for Genetic Conditions: An Analysis of USA Commercial Claims Data.

Introduction: Healthcare payers in the USA increasingly cover genetic testing, including exome sequencing (ES), for pediatric indications. Analysis of claims data enables understanding of utilization and costs in real-world settings. The objective of this study was to describe genetic test utilization, diagnostic outcomes, and costs for children who received ES as well as for those who received less comprehensive forms of genetic testing, along with their families.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.
