While obesity and its associated complications, mainly diabetes and hypertension, have been the largest public health problems of modern world, the emerging data suggests an increasing prevalence of primary hyperaldosteronism (PA) as one of the most common undiagnosed causes of hypertension. We believe that rising prevalence of PA in the era of high rates of obesity is likely not a chance finding but is deeply intersected with the rising rates of obesity. Higher serum aldosterone concentrations and urinary aldosterone excretion have been observed in patients with increased body mass index or larger waist circumference. ⋯ The aldosterone excess in these cases can be labelled as acquired hyperaldosteronism to differentiate it from the non-obesity related classical cases of PA. Because of serious consequences, recognizing aldosterone excess in obesity is important, as it gives a more compelling reason for weight loss and guidance to choosing pharmacotherapy wisely. Dietary sodium restriction and mineralocorticoid receptor antagonists play important roles in the management of PA associated with obesity.

A 52-year-old male comes to the internal medicine clinic for a follow-up for the management of hypertension. He was initially diagnosed with hypertension 5 years ago. His other past medical history includes obesity and hyperlipidemia. ⋯ Multiple comorbidities, including obesity, sleep apnea, chronic kidney disease, heart failure, and diabetes mellitus, are associated with resistant hypertension. Our understanding of the potential etiologies for this condition continues to evolve rapidly. We used a narrative review to explore four research areas in the pathophysiology of resistant hypertension (the sympathetic nervous system, aldosterone excess, endothelial dysfunction, and inflammation) and explore the novel therapies currently in development.

Building expertise in climate and planetary health among healthcare professionals cannot come with greater urgency as the threats from climate change become increasingly apparent. Current and future healthcare professionals-particularly internists-will increasingly need to understand the interconnectedness of natural systems and human health to better serve their patients longitudinally. Despite this, few national medical societies and accreditation bodies espouse frameworks for climate change and planetary health-related education at the undergraduate (UME), graduate (GME), and continuing (CME) medical education level. ⋯ In this position statement, we build from the related SGIM Climate and Health position statement, and review and synthesize existing position statements made by US-based medical societies and accreditation bodies that focus on climate change and planetary health-related medical education, identify gaps using Bloom's Hierarchy, and provide recommendations on behalf of SGIM regarding the development of climate and planetary health curricula development. Identified gaps include (1) limited systematic approach to climate and planetary health medical education at all levels; (2) minimal emphasis on learner-driven approaches; (3) limited focus on physician and learner well-being; and (4) limited role for health equity and climate justice. Recommendations include a call to relevant accreditation bodies to explicitly include climate change and planetary health as a competency, extend the structural competency framework to climate change and planetary health to build climate justice, proactively include learners in curricular development and teaching, and ensure resources and support to design and implement climate and planetary health-focused education that includes well-being and resiliency.

There is growing concern that pulse oximeters are routinely less accurate in hospitalized patients with darker skin pigmentation, in turn increasing risk of undetected (occult) hypoxemia and adverse clinical outcomes. The aim of this systematic review and meta-analysis was to synthesize evidence on racial and ethnic disparities in occult hypoxemia prevalence and clinical impacts of undetected hypoxemia. ⋯ This review and included primary studies rely on self-identified race or ethnicity, which may obscure variability in occult hypoxemia risk. Findings underscore that clinicians should be aware of the risk of occult hypoxemia in hospitalized patients with darker skin pigmentation. Moreover, oximetry data from included studies suggests that the accuracy of pulse oximeters could vary substantially from patient to patient and even within individual patients.

Professional society guidelines are evidence-based recommendations intended to promote standardized care and improve health outcomes. Amid increased recognition of the role racism plays in shaping inequitable healthcare delivery, many researchers and practitioners have critiqued existing guidelines, particularly those that include race-based recommendations. Critiques highlight how racism influences the evidence that guidelines are based on and its interpretation. However, few have used a systematic methodology to examine race-based recommendations. This review examines hypertension guidelines, a condition affecting nearly half of all adults in the United States (US), to understand how guidelines reference and develop recommendations related to race. ⋯ Hypertension guidelines largely refer to race as a distinct and natural category rather than confront the longstanding history of racism within and beyond the medical system. Normalizing race as a biological rather than social construct fails to address racism as a key determinant driving inequities in cardiovascular health. These changes are necessary to produce meaningful structural solutions that advance equity in hypertension education, research, and care delivery.
