Climate change affects patient health through an array of exposures, including increasing heatwaves, extreme weather events, poor air quality, and expanding vector-borne illnesses. Physicians are at the forefront of addressing the health consequences of these exposures with patients, and environmental sustainability has become a priority for health care organizations. Accordingly, climate change and health is becoming a critical area for graduate medical education (GME).

Article Synopsis
  • Micro-environmental factors like stromal and immune cells, along with hormones, significantly influence the progression of melanoma.
  • A study with 89 melanoma patients revealed a notable link between elevated gastrin levels and increased melanoma thickness and metastasis, suggesting higher cancer progression risks.
  • Gastrin was shown to promote melanoma cell migration and invasion through CCK2 receptors, with interactions in the tumor environment potentially exacerbating these effects, especially when combined with dermal fibroblasts/myofibroblasts.

African Americans are disproportionately affected by hypertension, a modifiable contributor to multiple chronic diseases and premature death. Primary care physicians play an important role in hypertension control. Home blood pressure monitoring (HBPM) is an evidence-based method for confirming diagnosis and monitoring hypertension over time.

Changes in the abundance of individual proteins in the proteome can be elicited by modulation of protein synthesis (the rate of input of newly synthesized proteins into the protein pool) or degradation (the rate of removal of protein molecules from the pool). A full understanding of proteome changes therefore requires a definition of the roles of these two processes in proteostasis, collectively known as protein turnover. Because protein turnover occurs even in the absence of overt changes in pool abundance, turnover measurements necessitate monitoring the flux of stable isotope-labeled precursors through the protein pool such as labeled amino acids or metabolic precursors such as ammonium chloride or heavy water.

Background: The clinical learning environment (CLE) is a priority focus in medical education. The Accreditation Council for Graduate Medical Education Clinical Learning Environment Review's (CLER) recent addition of teaming and health care systems obligates educators to monitor these areas. Tools to evaluate the CLE would ideally be: (1) appropriate for all health care team members on a specific unit/project; (2) informed by contemporary learning environment frameworks; and (3) feasible/quick to complete.

Intracranial electroencephalography (EEG) is commonly used to study epileptogenesis and epilepsy in experimental models. Chronic gliosis and neurodegeneration at the injury site are known to be associated with surgically implanted electrodes in both humans and experimental models. Currently, however, there are no reports on the impact of intracerebral electrodes on proteins in the hippocampus and proinflammatory cytokines in the cerebral cortex and plasma in experimental models.

Injuries to the intra-articular anterior cruciate ligament (ACL) and the extra-articular medial collateral ligament (MCL) result in significant knee joint instability, pain, and immobility. Moderate endurance-type exercise can increase ligament strength but little is known on the effect of short-term regular bouts of high-intensity exercise on the extracellular matrix (ECM) structure of knee ligaments. Therefore, this study aimed to identify the effect of short-term regular bouts high exercise on the proteome of the rat ACL and MCL using mass spectrometry.
