Groundwater releases CO to diverse global coastal ecosystems.

Coastal ecosystems play a major role in marine carbon budgets, but substantial uncertainties remain in the sources and fluxes of coastal carbon dioxide (CO). Here, we assess when, where, and how submarine groundwater discharge (SGD) releases CO to shallow coastal ecosystems. Time-series observations of dissolved CO and radon (Rn, a natural groundwater tracer) across 40 coastal systems from 14 countries revealed large SGD-derived CO fluxes.

Panniculitis in dermatomyositis: A systematic review of the clinicopathologic features.

Background: Panniculitis in patients with dermatomyositis (PDMS) is rare.

Objectives: Assess the clinicopathologic features described for PDMS.

Methods: A systematic review of the PubMed/MEDLINE database was performed.

Impact of New York City's 4-year multi-component natural experiment to improve elementary school physical education on student cardiorespiratory fitness.

Background: School physical education is an important population-level health intervention for improving youth fitness. This study estimated the impact of New York City's PE Works program - which included providing PE teachers, training for classroom teachers, and administrative/ teacher support for PE - on student cardiorespiratory fitness as measured by the FitnessGram's 15-meter PACER test for aerobic capacity.

Methods: This longitudinal study (2014/15-2018/19) includes 581 elementary schools (n = 315,999 4th /5th -grade students; 84% non-white; 74% who qualify for free or reduced-price meals, a proxy for socioeconomic status).

Oncocytic Adrenal Neoplasms: Clinical Profiles and Long-Term Outcomes.

Oncocytic adrenal neoplasms, defined by ≥90 % of oncocytic cells, are rare. The significance of oncocytic changes within an adrenal neoplasm remains unclear. A retrospective study of adults who underwent adrenalectomy at a large center identified pure oncocytic neoplasms on final pathology (1997-2022).
