Background: There is a wide treatment gap between evidence-based guidelines and their implementation in primary care.

Objective: To evaluate the extent to which physicians "literally" follow guidelines for secondary prevention of dyslipidemia and the extent to which they practice "substitute" therapeutic measures.

Methods: We performed a post hoc analysis of data collected in a prospective cluster randomized trial. The participants were 130 primary care physicians treating 7745 patients requiring secondary prevention of dyslipidemia. The outcome measure was physician "literal" adherence or "substitute" adherence. We used logistic regressions to evaluate the effect of various clinical situations on “literal” and “substitute” adherence.

Results: "Literal" adherence was modest for ordering a lipoprotein profile (35.1%) and for pharmacotherapy initiations (26.0%), but rather poor for drug up-titrations (16.1%) and for referrals for specialist consultation (3.8%). In contrast, many physicians opted for "substitute" adherence for up-titrations (75.9%) and referrals for consultation (78.7%). Physicians tended to follow the guidelines “literally” in simple clinical situations (such as the need for lipid screening) but to use "substitute" measures in more complex cases (when dose up-titration or metabolic consultation was required). Most substitute actions were less intense than the actions recommended by the guidelines.

Conclusions: Physicians often do not blindly follow guidelines, but rather evaluate their adequacy for a particular patient and adjust the treatment according to their assessment. We suggest that clinical management be evaluated in a broader sense than strict guideline adherence, which may underestimate physicians' efforts.

Pulmonary epithelioid hemangioendothelioma (PEH), previously known as "intravascular bronchoalveolar tumor," is a rare vascular malignancy with an unpredictable prognosis. Treatment can vary from observation in asymptomatic patients to surgery in patients with resectable disease or chemotherapy in patients with disseminated disease. This report describes the clinical, radiological and pathological features of three cases of PEH and a review of the current literature.

Background: Heart failure with preserved systolic left ventricular function is a major cause of cardiac disability.

Objectives: To examine the prevalence, characteristics and late clinical outcome of patients hospitalized with HF-PSF[1] on a nationwide basis in Israel.

Methods: The Israel nationwide HF survey examined prospectively 4102 consecutive HF patients admitted to 93 internal medicine and 24 cardiology departments in all 25 public hospitals in the country. Echocardiographic LV function measurements were available in 2845 patients (69%). The present report relates to the 1364 patients who had HF-PSF (LV ejection fraction ≥ 40%).

Results: Mortality of HF-PSF patients was high (in-hospital 3.5%, 6 months 14.2%, 12 months 22.0%), but lower than in patients with reduced systolic function (all P < 0.01). Mortality was higher in patients with HF as the primary hospitalization diagnosis (16.0% vs. 12.5% at 6 months, P = 0.07 and 26.2% vs. 18.0% at 12 months, P = 0.0002). Patients with HF-PSF who died were older (78 ± 10 vs. 71 ± 12 years, P < 0.001), more often female (P = 0.05) and had atrial fibrillation more frequently (44% vs. 33%, P < 0.01). There was also a relationship between mortality and pharmacotherapy: after adjustment for age and co-morbid conditions, mortality was lower in patients treated with angiotensin-converting enzyme inhibitors (P = 0.0003) and angiotensin receptor blockers (P = 0.002) and higher in those receiving digoxin (P = 0.003) and diuretic therapy (P = 0.009).

Conclusions: This nationwide survey highlights the very high late mortality rates in patients hospitalized for HF without a decrease in systolic function. The findings mandate a focus on better evidence-based treatment strategies to improve outcome in HF-PSF patients.

The prevalence of obesity worldwide has risen sharply during the last four decades. The etiology of obesity is complex and includes a host of genetic influences in addition to the overconsumption of energy coupled with a sedentary lifestyle. Obesity is known to cause or exacerbate many co-morbid conditions such as diabetes, hypertension, dyslipidemia, coronary heart disease, stroke, certain cancers, arthritis and obstructive sleep apnea. Modest weight losses of 5–10% of actual weight are related to significant improvements in co-morbid conditions, but unfortunately the rate of recidivism with short-term therapy for obesity is high. The recent recognition of obesity as a chronic disease that should be treated with long-term programs and possibly with polypharmacy, and the alarming increase in its prevalence, have prompted extensive research and the development of new pharmacotherapy.
