RESUMEN
Dysfunction of the coronary microvasculature has become increasingly recognized as an important mechanism of myocardial ischemia in patients without obstructive coronary artery disease. The causes and management of coronary microvascular dysfunction remain poorly understood and are still largely based on extrapolation of epicardial coronary artery disease data. Quantification of myocardial blood flow and flow reserve have improved diagnosis, though important questions remain. In this review, we explain current understanding of the spectrum of pathophysiology of coronary microvascular dysfunction, summarize current diagnostic techniques to assess for coronary microvascular dysfunction, and appraise the limited data on management options specifically for patients with coronary microvascular dysfunction.

Among patients with COVID-19 evaluated in outpatient settings, factors associated with hospitalization remain poorly understood. Multivariable regressions were used to assess sociodemographic and clinical factors associated with increased odds of hospitalization among patients with confirmed COVID-19 between March 18, 2020 through April 25, 2020 at a community-based outpatient clinic in Massachusetts. Older age, BMI ≥ 25, self-reported dizziness/lightheadedness, temperature ≥ 99.5°F, tachycardia, and oxygen saturation < 95% were associated with increased odds of hospitalization after adjustment for age, sex, and BMI. There was also an association between speaking Spanish as primary language and increased odds of hospitalization (compared to English, adjusted OR = 2.99 [95% CI 1.39, 6.39]). Speaking Portuguese as primary language was not associated with increased odds of hospitalization (compared to English, adjusted OR = 1.83 [0.78, 4.28]). In addition to several clinical risk factors established among inpatients, our study found that primarily speaking Spanish, but not Portuguese, was a marker of hospitalization risk among a diverse outpatient cohort of patients with COVID-19.

Humanitarian aid workers caring for Syrian refugees face major stressors as they attend to refugees' needs on the field. Without adequate psychosocial support, evidence has shown that fieldworkers experience high burnout and turnover as well as long-term poor mental health. Unfortunately, scarce training in this regard leaves them ill-equipped to care for themselves and practice resilience while handling trauma in the field. This paper highlights our reflection on working with mindfulness programs during humanitarian crises, specifically how our program, Stress Management and Relaxation Response Training (SMART), has helped over time fieldworkers and the community they cared for. We propose that programs targeting the wellbeing of fieldworkers should be prioritized as part of efforts to improve the international aid response although they may require impeccable coordination and generous resources. We encourage donors to fund those projects viewed as special social protection programs building resilience and strengthening within system support. We argue that this will increase the efficacy of the crisis intervention and work towards sustainable peace building.
