The evolution of academic advisor and resident dyadic coaching relationships: a two-year longitudinal qualitative study.

Adv Health Sci Educ Theory Pract

December 2024

Department of Medicine Canada Research Chair in Health Professions Education and scientist at the Wilson Centre for Education, University of Toronto, Toronto, ON, Canada.

Implementing competency based medical education (CBME) has generated enormous amounts of assessment data. To help residents synthesize and use these data, some programs have appointed academic advisors (AA) to 'coach over time'. This study explored how resident and faculty AA dyads perceived their relationship developing and evolving, and the extent to which it aligned with 'coaching over time'.

Background: Covered stent correction for a sinus venosus atrial septal defect (SVASD) was first performed in 2009. This innovative approach was initially viewed as experimental and was reserved for highly selected patients with unusual anatomic variants. In 2016, increasing numbers of procedures began to be performed, and in several centers, it is now offered as a standard of care option alongside surgical repair.

Background: Although some evidence suggests that alcohol, substance use, and mental health issues diminish adherence to HIV Pre-Exposure Prophylaxis (PrEP) among gay, bisexual, and other men-who-have-sex-with-men (gbMSM), findings are somewhat inconsistent and have primarily derived from studies involving non-random samples. Medical chart extraction can provide unique insight by in part surmounting sampling-related limitations, as data for entire PrEP clinic populations can be examined. Our investigation entailed comprehensive chart extraction to assess the extent to which chart-reported alcohol, substance use, and mental health issues were associated with chart-reported PrEP nonadherence.

Severe hypophosphataemia and hypocalcaemia following intravenous ferric derisomaltose and denosumab administration.

BMJ Case Rep

December 2024

Division of Endocrinology, Department of Medicine, Jewish General Hospital, McGill University, Montreal, Quebec, Canada.

Serum calcium and phosphorus levels are tightly regulated by the calciotropic hormone parathyroid hormone, fibroblast growth factor 23 and 1,25(OH) vitamin D. Commonly prescribed therapies for iron-deficiency anaemia (IDA) such as ferric carboxymaltose and ferric derisomaltose (FDM) have been shown to disrupt phosphorus homeostasis, resulting in hypophosphataemia. Similarly, denosumab use can result in hypocalcaemia due to the inhibition of osteoclastic maturation, activity and survival.

Background: In STREAM-1 (Strategic Reperfusion Early After Myocardial Infarction), excess intracranial hemorrhage occurred in patients aged ≥75 years receiving full-dose tenecteplase as part of a pharmaco-invasive strategy, whereas no further intracranial hemorrhage occurred after halving the tenecteplase dose. In STREAM-2 (Second Strategic Reperfusion Early After Myocardial Infarction), half-dose tenecteplase was an effective and safe pharmaco-invasive strategy in older patients with ST-segment-elevation myocardial infarction presenting within <3 hours, compared with primary percutaneous coronary intervention (PCI). We prespecified evaluating the efficacy and safety of a half-dose versus full-dose pharmaco-invasive strategy and compared the half-dose pharmaco-invasive strategy to primary PCI in patients aged ≥75 years.

L-arginine: glycine amidinotransferase (AGAT) gained academic interest as the rate-limiting enzyme in creatine biosynthesis and its role in the regulation of creatine homeostasis. Of clinical relevance is the diagnosis of patients with AGAT deficiency but also the potential role of AGAT as therapeutic target for the treatment of another creatine deficiency syndrome, guanidinoacetate N-methyltransferase (GAMT) deficiency. Applying a stable isotope-labeled substrate method, we utilized ARG 15N (ARG-δ2) and GLY 13C15N (GLY-δ3) to determine the rate of 1,2-13C,15N guanidinoacetate (GAA-δ5) formation to assess AGAT activity in various mouse tissue samples and human-derived cells.

Transfer of chirality, or transmission of asymmetric information from one system to another, plays an essential role in fundamental biological and chemical processes and, therefore, is essential for life. This phenomenon also holds immense potential in spintronics in the context of chirality-induced spin selectivity (CISS). In the CISS, the spatial arrangement of chiral molecules influences the spin state of electrons during the charge-transfer processes.

Background: Modest weight and lipid changes have been observed in cabotegravir plus rilpivirine long-acting (CAB+RPV LA) Phase 3/3b studies. The SOLAR study included standardized evaluations of weight and metabolic changes in people living with HIV switching to CAB+RPV LA dosed every 2 months (Q2M) vs. continuing bictegravir/emtricitabine/tenofovir (BIC/FTC/TAF).

Background And Objectives: Ocular myasthenia gravis (OMG) causes disabling ocular symptoms of ptosis and diplopia, but a validated disease-specific patient-reported outcome measure (PROM) has not been reported. We sought to validate a novel PROM for OMG, OMG Rating Scale Questionnaire (OMGRate-q), as a measure of visual functioning to support patient-centered care.

Methods: This was a prospective study of patients aged 18 years and older with OMG receiving care at 3 medical centers (January 2022-October 2023).

Bacterial noncoding RNAs fulfill a variety of cellular functions as catalysts, as scaffolds in protein complexes or as regulators of gene expression. They often exhibit complex tertiary structures that are a key determinant of their biochemical function. Here, we characterize the structured "raiA motif" RNA from Clostridioides difficile, which is conserved in more than 2,500 bacterial species from the phyla Bacillota and Actinomycetota.

Gender differences in the context of interventions for improving health literacy in migrants: a qualitative evidence synthesis.

Cochrane Database Syst Rev

December 2024

Cochrane Haematology, Institute of Public Health, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany.

Background: Health literacy can be defined as a person's knowledge, motivation and competence in four steps of health-related information processing - accessing, understanding, appraising and applying health-related information. Individuals with experience of migration may encounter difficulties with or barriers to these steps that may, in turn, lead to poorer health outcomes than those of the general population. Moreover, women and men have different health challenges and needs and may respond differently to interventions aimed at improving health literacy.

Hypoxia-inducible factor prolyl hydroxylase (PHD) inhibitors have been approved for treating renal anemia yet have failed clinical testing for inflammatory bowel disease because of a lack of efficacy. Here we used a multimodel multimodal generative artificial intelligence platform to design an orally gut-restricted selective PHD1 and PHD2 inhibitor that exhibits favorable safety and pharmacokinetic profiles in preclinical studies. ISM012-042 restores intestinal barrier function and alleviates gut inflammation in multiple experimental colitis models.

Emulsifiers play an essential role in the flow behaviour of confectionery products such as chocolate. This research associated emulsifier adsorption onto sugar crystals and its effects on the flow properties of model sugar-in-oil suspensions. A new method to quantify emulsifier adsorption onto sugar crystals dispersed in oil was developed by exploiting the relationship between oil-water interfacial tension and unadsorbed emulsifier in the continuous oil phase.

Structurally intact native forests free from major human pressures are vitally important habitats for the persistence of forest biodiversity. However, the extent of such high-integrity forest habitats remaining for biodiversity is unknown. Here, we quantify the amount of high-integrity tropical rainforests, as a fraction of total forest cover, within the geographic ranges of 16,396 species of terrestrial vertebrates worldwide.
