Pulmonary Hypertension: Diagnosis and Treatment.

Pulmonary hypertension is a common, complex group of disorders that result from different pathophysiologic mechanisms but are all defined by a mean pulmonary arterial pressure of 25 mm Hg or greater. Patients often initially present to family physicians; however, because the symptoms are typically nonspecific or easily attributable to comorbid conditions, diagnosis can be challenging and requires a stepwise evaluation. There is limited evidence to support screening of asymptomatic individuals. Echocardiography is recommended as the initial step in the evaluation of patients with suspected pulmonary hypertension. A definitive diagnosis cannot be made on echocardiographic abnormalities alone, and some patients require invasive evaluation by right heart catheterization. For certain categories of pulmonary hypertension, particularly pulmonary arterial hypertension, treatment options are rapidly evolving, and early diagnosis and prompt referral to an expert center are critical to ensure the best prognosis. There are no directed therapies for many other categories of pulmonary hypertension; therefore, family physicians have a central role in managing contributing comorbidities. Other important considerations for patients with pulmonary hypertension include influenza and pneumonia immunizations, contraception counseling, preoperative assessment, and mental health.

Hypertension in Women: Evaluation and Management.

Hypertension is the most commonly encountered chronic medical condition in primary care and one of the most significant modifiable cardiovascular risk factors for women and men. Timely diagnosis and evidence-based management offer an important opportunity to reduce the risk of hypertension-related morbidity and mortality, including cardiovascular events, end-stage renal disease, and heart failure. Clinical trials have shown significant improvements in patient-oriented outcomes when hypertension is well-controlled, yet many hypertensive patients remain undiagnosed, uncontrolled, or managed with inappropriate pharmacotherapy. This article discusses the initial diagnosis, evaluation, and management of hypertension in nonpregnant women, with topics for obstetrician-gynecologists and women's health providers.

Folic acid and human reproduction-ten important issues for clinicians.

This article presents data on the current best evidence-based clinical practices and controversies surrounding folic acid supplementation/fortification for the prevention of neural tube defects (NTDs) during early pregnancy. Formatted as a series of ten clinical questions, answers and extensive discussion are provided for each point. We assess the history and evidence behind supplementation and fortification, racial/ethnic disparities in NTDs on a global scale, and present information on risk factors for NTDs other than dietary folic acid deficiency. Also discussed are public health challenges, including disparities in NTD rates, population-wide monitoring of NTDs, and tracking safety data in the post-fortification era. Emerging data are also reviewed regarding the role folic acid may play in malignant processes, cardiovascular disease, male fertility, and other medical conditions.
