Reducing severe intraventricular haemorrhage rates in <26-week preterm infants with bedside assessment and care bundle implementation.

Aim: To assess staff adherence to a 'Preterm Brain Injury Prevention Bundle', and its effectiveness in reducing severe intraventricular haemorrhage (IVH) rates and risk factors in extremely preterm infants born at <26 weeks' gestation.

Methods: Adherence to the bundle was assessed using a novel bedside assessment tool, with immediate feedback to bedside staff post-assessment. Data on IVH rates and associated risk factors were stratified by IVH severity, and compared between pre- and post-bundle implementation.

Occupational lead exposure and amyotrophic lateral sclerosis survival in the Danish National Patient Registry.

Objectives: We investigated the relationship between occupational lead exposure and amyotrophic lateral sclerosis (ALS) survival in Denmark.

Methods: We identified 2,161 ALS cases diagnosed from 1982 to 2013 with at least 5 years of employment history before ALS diagnosis, via the Danish National Patient Registry. Cases were followed until March 2017.

Effect of socioeconomic factors during the early COVID-19 pandemic: a spatial analysis.

Background: Spatial variability of COVID-19 cases may suggest geographic disparities of social determinants of health. Spatial analyses of population-level data may provide insight on factors that may contribute to COVID-19 transmission, hospitalization, and death.

Methods: Generalized additive models were used to map COVID-19 risk from March 2020 to February 2021 in Orange County (OC), California.

SARS-CoV-2 antibody seroprevalence among firefighters in Orange County, California.

Objectives: We conducted serological SARS-CoV-2 antibody testing from October to November 2020 to estimate the SARS-CoV-2 seroprevalence among firefighters/paramedics in Orange County (OC), California.

Methods: OC firefighters employed at the time of the surveillance activity were invited to participate in a voluntary survey that collected demographic, occupational and previous COVID-19 testing data, and a SARS-CoV-2 immunoglobulin (Ig)G antibody blood test. We collected venous blood samples using mobile phlebotomy teams that travelled to individual fire stations, in coordination with an annual tuberculosis testing campaign for firefighters employed by OC Fire Authority (OCFA), and independently for firefighters employed by cities.

A spatial analysis of birth defects in Texas, 1999-2011.

Background: The etiologies of major birth defects are still unclear and few spatial analyses have been conducted in the United States. Spatial analyses of individual-level data can help elucidate environmental and social risk factors.

Methods: We used generalized additive models to analyze 52,955 cases of neural tube defects, congenital heart defects (CHDs), gastroschisis, and orofacial cleft defects, and sampled from 642,399 controls born between 1999 and 2011 in Texas.

Birth defects and unconventional natural gas developments in Texas, 1999-2011.

Unconventional natural gas developments (UNGD) may release air and water pollutants into the environment, potentially increasing the risk of birth defects. We conducted a case-control study evaluating 52,955 cases with birth defects and 642,399 controls born between 1999 and 2011 to investigate the relationship between UNGD exposure and the risk of gastroschisis, congenital heart defects (CHD), neural tube defects (NTDs), and orofacial clefts in Texas. We calculated UNGD densities (number of UNGDs per area) within 1, 3, and 7.

Spatiotemporal analysis of human exposure to halogenated flame retardant chemicals.

Human exposure to flame retardants occurs in microenvironments due to their ubiquitous presence in consumer products and building materials. Recent research suggests higher levels of exposure through elevated surface dust (ESD) compared to floor dust (FD). However, it is unclear whether this pattern is consistent in different microenvironments beyond the home.

Potential human exposure to halogenated flame-retardants in elevated surface dust and floor dust in an academic environment.

Most households and workplaces all over the world possess furnishings and electronics, all of which contain potentially toxic flame retardant chemicals to prevent fire hazards. Indoor dust is a recognized repository of these types of chemicals including polybrominated diphenyl ethers (PBDEs) and non-polybrominated diphenyl ethers (non-PBDEs). However, no previous U.
