An outbreak of coronavirus disease 2019 (COVID-19) caused by a novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) began in Wuhan, Hubei, China, in December 2019 and spread rapidly worldwide. The response by the Alberta Precision Laboratories, Public Health Laboratory (ProvLab), AB, Canada, included the development and implementation of nucleic acid detection-based assays and dynamic changes in testing protocols for the identification of cases as the epidemic curve increased exponentially. This rapid response was essential to slow down and contain transmission and provide valuable time to the local health authorities to prepare appropriate response strategies. As of May 24, 2020, 236,077 specimens were tested, with 6,475 (2.74%) positives detected in the province of Alberta, Canada. Several commercial assays are now available; however, the response from commercial vendors to develop and market validated tests is a time-consuming process. In addition, the massive global demand made it difficult to secure a reliable commercial supply of testing kits and reagents. A public health laboratory serves a unique and important role in the delivery of health care. One of its functions is to anticipate and prepare for novel emerging pathogens with a plan for pandemic preparedness. Here, we outline the response that involved the development and deployment of testing methodologies that evolved as SARS-CoV-2 spread worldwide, the challenges encountered, and mitigation strategies. We also provide insight into the organizational structure of how a public health response is coordinated in Alberta, Canada, and its benefits.

Evaluating the factor structure of the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) in adults with congenital heart disease.
Clin Neuropsychol

Department of Psychiatry and Psychology, Mayo Clinic, Rochester, MN, USA.
: While it is generally assumed that common neurobehavioral assessments, such as the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV), function similarly in clinical and non-clinical populations, this has not been validated in adults with congenital heart disease (CHD). In this study, we examined the latent factor structure of the WAIS-IV in adults with d-transposition of the great arteries (d-TGA) who participated in the Boston Circulatory Arrest Study. : The WAIS-IV was administered as part of a larger assessment battery.

Background: People who inject drugs (PWID) are especially vulnerable to harms from opioid use disorder (OUD). Medications for OUD (MOUD) effectively reduce overdose and infectious disease transmission risks.
Objective: We investigate whether state Medicaid coverage for methadone and buprenorphine is related to past-year MOUD use among PWID using cross-sectional, multilevel analyses with individual-level data on PWID from the Centers for Disease Control and Prevention's 2018 National HIV Behavioral Surveillance.
Clinical remission in patients with severe eosinophilic asthma treated with mepolizumab: A analysis of RELIght study.
Allergy Asthma Proc

2nd Respiratory Department, Attikon University Hospital, National and Kapodistrian University of Athens Medical School, Athens, Greece.
Remission of asthma can occur as part of the natural history of the disease; however, the use of biologics can result in disease remission in some patients. In this post hoc analysis of the RELIght study, we aimed to evaluate clinical remission in real life among patients treated with mepolizumab, to detect possible differences between "remitters" and "nonremitters," and to evaluate possible predictors of remission. Clinical remission was defined as the absence of asthma exacerbations, discontinuation of oral corticosteroids (OCS), achievement of asthma control (Asthma Control Test [ACT] ≥ 20), and stable or improved lung function.

Background: Doulas, non-clinical professionals who provide support throughout the perinatal period, can positively impact patient experiences and clinical outcomes during birth. Doulas often support hospital-based births without being employed by the hospital system, resulting in varied relationships with hospitals and clinicians. Systems-level changes are needed to maximize collaboration between hospitals and doulas to ensure facilitation of, and not barriers to, doula support.

Background: Integrating multi-layered information can enhance the accuracy of genomic prediction for complex traits. However, the improvement and application of effective strategies for genomic prediction (GP) using multi-omics data remains challenging.
Methods: We generated 11 feature sets for sequencing variants from genomics, transcriptomics, metabolomics, and epigenetics data in beef cattle, then we assessed the contribution of functional variants using genomic restricted maximum likelihood (GREML).
