Postural orthostatic tachycardia syndrome (POTS), the most common form of orthostatic intolerance in young people, affects approximately 500,000 people in the United States alone, typically young women at the peak of their education and the beginning of their working lives. This is a heterogeneous disorder, the pathophysiology and mechanisms of which are not well understood. There are multiple contributing factors and numerous potential mimics. This review details the most current views on the potential causes, comorbid conditions, proposed subtypes, differential diagnoses, evaluations, and treatment of POTS from cardiological and neurological perspectives. 相似文献

This paper provides longitudinal examination of women’s health and sexual risk trajectories in US exotic dance clubs, which represent an important commercial setting for the economic mainstreaming of sexual services and an important target for public health programmes. Between July 2014 and May 2015, two semi-structured interviews (at baseline and at three months) were conducted with 24 female exotic dancers who had recently started working in in Baltimore City, USA. Results from a constant comparative analysis point to the interrelationship between the structures of the club setting, including the social context, and women’s agentic practices concerning their sexual health. Study findings highlight the centrality of the interrelationship between individual- and structural-level experiences in influencing dancers’ risk behavior. Findings point to the need for interventions to empower women both individually and collectively so as to provide the foundation for longer-term structural change. 相似文献

This study examined the 2010 Centers for Medicare and Medicaid Services National Plan and Provider Enumeration System's National Provider Identifier (NPI) data to ascertain their usefulness to determine the distribution of advanced practice registered nurses (APRNs) in rural and urban areas of the United States. This study showed that certified registered nurse anesthetists were more likely to practice in rural areas in states with greater practice autonomy. For nurse practitioners, the findings were similar but were of borderline statistical significance. These findings imply that practice autonomy should be considered as a state-level strategy to encourage rural practice by APRNs. 相似文献
