Background: Contemporary therapies improve prognosis and may restore left ventricular (LV) size and function.
Objectives: To examine the prevalence, clinical features and therapies associated with reverse remodeling (RR) in dilated cardiomyopathy (DCM).
Methods: The study group comprised 188 DCM patients who had undergone two echo examinations at least 6 months apart. RR was defined as increased LV ejection fraction (LVEF) by ≥ 10% concomitant with ≥ 10% decreased LV end-diastolic dimension.
Results: RR occurred in 50 patients (26%) and was associated with significantly reduced end-systolic dimension, left atrial size, grade of mitral regurgitation, and pulmonary artery pressure. NYHA class improved in the RR group. RR was less common in familial DCM and a long-standing disease and was more prevalent in patients with prior exposure to chemotherapy. Recent-onset disease, lower initial LVEF and normal electrocardiogram were identified as independent predictors of RR. Beta-blocker dose was related to improved LVEF but not to RR. Over a mean follow-up of 23 months, 16 patients (12%) from the 'no-RR' group died or underwent heart transplantation compared to none from the RR group (P < 0.01).
Conclusions: Contemporary therapies led to an an improvement in the condition of a considerable number of DCM patients. A period of close observation while optimizing medical therapy should be considered before deciding on invasive procedures.

Background: Physicians’ occupational environment includes exposures to potential carcinogenic. Factors on a regular basis. The prevalence of specific tumor types and subsequent mortality are reported to be elevated in physicians.
Objectives: To assess the incidence of various cancer types among Israeli physicians of various specialties, as compared with the general population, and to determine the role, if any, of gender and ethnicity.
Methods: This historical retrospective cohort analysis incorporated data on Israeli officially licensed physicians and information retrieved from the Israel National Cancer Registry database (INCR). Physicians were divided into five groups: 1) non-specialists, 2) internists, 3) pediatricians, 4) surgeons, and 5) potentially at-risk specialties. Data were collected retrospectively for the years 1980–2007.
Results: The study cohort comprised 37,789 physicians, of whom 33,393 (88.37%) were Jews and 4396 (11.63%) were Arabs. Comparing Jewish physicians to the general population revealed higher rates of: a) breast cancer among female specialized physicians, and b) melanoma among specialized male and female physicians. All cancer types were more prevalent in the Arab physicians than in the general Arab population.
Conclusions: This study revealed incidences of specific cancer types among different medical specialties as compared to the general population. Hopefully, these findings will prompt changes in the occupational environment of physicians of particular specialties in order to reduce their high risk for cancer occurrence.
