GLUT1 exacerbates trophoblast ferroptosis by modulating AMPK/ACC mediated lipid metabolism and promotes gestational diabetes mellitus associated fetal growth restriction.

Background: Gestational diabetes mellitus (GDM) has been associated with several fetal complications, such as macrosomia and fetal growth restriction (FGR). Infants from GDM associated FGR are at increased risk for adult-onset obesity and associated metabolic disorders. However, the underlying mechanisms of GDM associated FGR remain to be explored.

The inflammatory microenvironment of the lung at the time of infection governs innate control of SARS-CoV-2 replication.

Severity of COVID-19 is affected by multiple factors; however, it is not understood how the inflammatory milieu of the lung at the time of SARS-CoV-2 exposure affects the control of viral replication. Here, we demonstrate that immune events in the mouse lung closely preceding SARS-CoV-2 infection affect viral control and identify innate immune pathways that limit viral replication. Pulmonary inflammatory stimuli including resolved, antecedent respiratory infections with or influenza, ongoing pulmonary infection, ovalbumin/alum-induced asthma, or airway administration of TLR ligands and recombinant cytokines all establish an antiviral state in the lung that restricts SARS-CoV-2 replication.

Using a systems thinking approach to map the global rise of ultra-processed foods in population diets.

A key driver of obesity and diet-related illness globally has been the increased consumption of ultra-processed foods (UPFs). This paper aimed to identify the key actors, structures, incentives, and dynamics that characterize the global UPF system and have led to the dominance of UPFs in population diets. Based on a narrative review and using a systems thinking approach, we developed a causal loop diagram (CLD) of the global UPF system.

Understanding the Politics of Food Regulation and Public Health: An Analysis of Codex Standard-Setting Processes on Food Labelling.

Background: The importance of the international food regulatory system to global health, is often overlooked. There are calls to reform this system to promote healthy and sustainable food systems centred on the Codex Alimentarius Commission (Codex), the United Nation's (UN's) standard-setting body. Yet this presents a significant political challenge, given Codex has historically prioritized food safety risks over wider harms to public health, and is dominated by powerful food exporting nations and industry groups with a primary interest in trade expansion.

A Rollercoaster of Grades Versus Growth in the Clerkship Year: A Phenomenological Study of Medical Student Experience with Competency Development.

Purpose: As competency-based medical education (CBME) continues to advance in undergraduate medical education, students are expected to simultaneously pursue their competency development while also discriminating themselves for residency selection. During the foundational clerkship year, it is important to understand how these seemingly competing goals are navigated.

Methods: In this phenomenological qualitative study, the authors describe the experience of 15 clerkship students taking part in a pilot pathway seeking to implement CBME principles.
