Health Care Utilization After a Visit to a Within-Group Family Physician vs a Walk-In Clinic Physician.

Purpose: Primary care access is a key health system metric, but little research has compared models to provide primary care access when one's regular physician is not available. We compared health system use after a visit with a patient's own family physician group (ie, within-group physician who was not the patient's primary physician) vs a visit with a walk-in clinic physician who was not part of the patient's family physician group.

Methods: We conducted a population-based, retrospective cohort study using administrative data from Ontario, Canada, including all individuals formally enrolled with a family physician, from April 1, 2019 to March 31, 2020.

In patients with the kidney-dysfunction triad, facilitated evidence-based care did not reduce hospitalizations at 1 y.

Disparities in preterm birth following the July 1995 Chicago heat wave.

Purpose: To evaluate if changes in preterm birth (PTB, <37 weeks of gestation) incidence differed between non-Hispanic (NH) Black and NH white births following the July 1995 Chicago heat wave-among the most severe U.S. heat waves since 1950.

The primary care COVID-19 integrated pathway: a quantitative study of rapid response to health and social impacts of COVID-19.

Context: The first wave of COVID-19 in Calgary, Alberta health zone accelerated Primary Care (PC) integration. Specifically, it connected Family Physicians (FPs) with their counterparts in the broader health system to deliver wraparound patient care through a COVID-19 Integrated Pathway (CIP). A key element of the CIP included a data sharing platform that facilitated the provision of test results directly to the FP identified by patients.

Building a Data Bridge: Policies, Structures, and Governance Integrating Primary Care Into the Public Health Response to COVID-19.

Purpose: The effective integration of primary care into public health responses to the COVID-19 pandemic, particularly through data sharing, has received some attention in the literature. However, the specific policies and structures that facilitate this integration are understudied. This paper describes the experiences of clinicians and administrators in Alberta, Canada as they built a data bridge between primary care and public health to improve the province's community-based response to the pandemic.

Real World Biologic Use and Switch Patterns in Severe Asthma: Data from the International Severe Asthma Registry and the US CHRONICLE Study.

Introduction: International registries provide opportunities to describe use of biologics for treating severe asthma in current clinical practice. Our aims were to describe real-life global patterns of biologic use (continuation, switches, and discontinuations) for severe asthma, elucidate reasons underlying these patterns, and examine associated patient-level factors.

Methods: This was a historical cohort study including adults with severe asthma enrolled into the International Severe Asthma Registry (ISAR; http://isaregistries.

Impact of Socioeconomic Status, Race and Ethnicity, and Geography on Prenatal Detection of Hypoplastic Left Heart Syndrome and Transposition of the Great Arteries.

Background: Prenatal detection (PND) has benefits for infants with hypoplastic left heart syndrome (HLHS) and transposition of the great arteries (TGA), but associations between sociodemographic and geographic factors with PND have not been sufficiently explored. This study evaluated whether socioeconomic quartile (SEQ), public insurance, race and ethnicity, rural residence, and distance of residence (distance and driving time from a cardiac surgical center) are associated with the PND or timing of PND, with a secondary aim to analyze differences between the United States and Canada.

Methods: In this retrospective cohort study, fetuses and infants <2 months of age with HLHS or TGA admitted between 2012 and 2016 to participating Fetal Heart Society Research Collaborative institutions in the United States and Canada were included.

CD8 lymphocyte depletion enhances the latency reversal activity of the SMAC mimetic AZD5582 in ART-suppressed SIV-infected rhesus macaques.

Inducing latency reversal to reveal infected cells to the host immune system represents a potential strategy to cure HIV infection. In separate studies, we have previously shown that CD8 T cells may contribute to the maintenance of viral latency and identified a novel SMAC mimetic/IAP inhibitor (AZD5582) capable of reversing HIV/SIV latency by activating the non-canonical (nc) NF-κB pathway. Here, we use AZD5582 in combination with antibody-mediated depletion of CD8α cells to further evaluate the role of CD8 T cells in viral latency maintenance.
