Background: There is little published information on the coronary risk characteristics of Palestinian women. However, there are documented lifestyle differences as well as socioeconomic inequalities between Arab and Jewish women in Israel.

Objectives: To compare the risk factor characteristics of coronary heart disease patients in Palestinian and Israeli women.

Methods: This study included 546 women (444 Jews and 102 Arabs) aged 35-74, all residents of Jerusalem, who underwent cardiac catheterization at the Hadassah-Hebrew University Medical Center between 2000 and 2003, and were confirmed to have coronary artery disease; Data on multiple risk factors were obtained from patient interviews and files.

Results: Compared with Jewish women, Arab women had a higher prevalence of diabetes, had borne more children/were younger, had a lower socioeconomic status, consumed jess alcohol and more olive oil, suffered more passive smoking and were less physically active. On the other hand, fewer Arab women had dyslipidemia, used hormone replacement therapy and had a family history of CHD.

Conclusions: Compared to Jewish women, Palestinian Arab women in Jerusalem appear to have more diabetes and exhibit lifestyle factors that generally increase the risk for CHD. Greater attention to primary prevention in this ethnic group is needed. This study suggests the need to investigate determinants of the metabolic syndrome and the possible role of passive smoking in Arab women as well as modes of intervention via health promotion and risk factor management in this population.
 

Preventive medicine is taking an increasingly central place in modern clinical practice, at least in primary care. What, if anything, does the Jewish rabbinic tradition have to say about keeping healthy? The delayed response of contemporary rabbis to the dangers of smoking, in particular, raises questions about the underlying principles that Halakhah* employs to approach health promotion. As is often the case in Halakhah, we may detect different streams of thought in the classical sources, which may be felt in the way contemporary issues are handled. Three approaches will be discussed. First, Maimonides, famous for the practical preventive approach in his medical writings, makes his philosophy clear both in his halakhic works and in his Guide for the Perplexed. For him, a healthy body is a prerequisite for a healthy soul. We must be free of physical suffering in order to be able to do the work of perfecting our souls. Second, the view that health is the reward for goodness and illness a punishment for sin as expounded or implied in the writings of Nahmanides, and of Ibn Ezra that the way to good health is to lead a good life. Third, an early midrashic** source picked up again much later by Rabbi Israel Meir Kagan (the Hafetz Hayim) gives the argument from custodianship – since the body is divine property we have a duty to look after it well. So for Maimonides there is a prior duty to keep healthy, while for Nahmanides the prior requirement is to repent of sin. For the Hafetz Hayim, keeping the body healthy is an independent duty in its own right. These then are the differences in basic approach that may affect the emphases that different rabbis today place on health maintenance and promotion.

Rembrandt van Rijn (1606–1669) left behind the largest collection of self-portraits in the history of art. These portraits were painted over a period of 41 years, using a realistic technique. To evaluate Rembrandt's aging process we studied 25 uncontested Rembrandt oil self-portraits by means of objective and descriptive techniques. By measuring brow position changes through the years, we demonstrated that brow descent started in the second half of the third decade and began to level out in the fourth decade. Based on Rembrandts' aging physiognomy, from age 22 to 63, we believe that Rembrandt did not suffer from temporal arteritis, hypothyroidism, rosacea, or rhynophima and that no other facial signs of systemic diseases are evident, contrary to the opinions expressed by other medical professionals. We suggest that Rembrandt suffered from melancholia or mild depression, and propose the possibility of chronic lead poisoning as a theoretical illness that he might have had.

Inherited forms of proteinuria constitute a rare and heterogeneous group of diseases, the most prominent of which is glomerular dysfunction, which leads to proteinuria. Investigation of the genetic background underlying these diseases has provided significant data on the normal operation of the glomerular filter. Among the different components of the glomerulus, the podocyte slit diaphragm is considered the main source for genetically derived protein alteration, which leads in turn to proteinuria. Investigation of the different proteins revealed that the lack of nephrin and podocin is the leading cause of several inherited forms of proteinuria. It was also proposed that the lack of podocin is linked to cardiac anomalies. This review suggests that the absence of slit diaphragm proteins and the open zipper phenomenon are associated with cardiac anomalies.

Background: Ethnicity has been associated with variance in warfarin treatment regimens in various settings.

Objectives: To determine whether ethnicity is associated with variance in patient management in Israel.

Methods: Data were extracted from the electronic patient records of Clalit Health Services clinics in the Sharon Shomron region. The study group comprised all patients treated with warfarin who performed international normalized ratio tests for at least 6 months in 2003. The proportion of tests of each patient within the target range was calculated, as was the crude average rates and 95% confidence intervals for Jewish and Arab patients. The data were then stratified by patient's gender, specialty of attending physician, patient's age, and the country where the physician studied medicine.

Results: We identified 2749 Jews and 293 Arabs who met the inclusion criteria of the study. The crude average rate of patients’ INR[1] tests within the target range was 62.3% among Jews (95% CI[2] 61.5–63.1) and 52.7% (95% CI 49.9–55.5) among Arabs. When stratified by gender, age, and the treating physician's specialty and country of education, the stratum-specific rates among Jewish patients were consistently higher than among Arabs.

Conclusions: These results suggest that cultural differences regarding adherence to recommendations for drug therapy in addition to genetic factors may be associated with this variance.

Objectives: To estimate the influence of phlebotomies on large artery (C1) and small artery compliance (C2) in PV patients by using non-invasive methods.

Methods: Short-term hemodynamic effects of phlebotomy were studied by pulse wave analysis using the HDI-Pulse Wave CR2000 (Minneapolis, MN, USA) before and immediately after venesection (300–500 ml of blood). We repeated the evaluation after 1 month to measure the long-term effects.

Results: Seventeen PV patients were included in the study and 47 measurements of arterial compliance were performed: 37 for short-term effects and 10 for long-term effects. The mean large artery compliance (C1) before phlebotomy was 12.0 ml/mmHg x 10 (range 4.5–28.6), and 12.6 ml/mmHg x 10 (range 5.2–20.1) immediately after phlebotomy (NS). The mean small artery compliance (C2) before and immediately after phlebotomy were 4.4 mg/mmHg x 10 (range 1.2–14.3) and 5.5 mg/mmHg x 10 (range 1.2–15.6) respectively (delta C2–1.1, P < 0.001). No difference in these parameters could be demonstrated in the long-term arm.

Conclusions: Phlebotomy immediately improves arterial compliance in small vessels of PV patients, but this effect is short lived.

Background: Despite significant advances in the therapy of heart failure, many patients still do not receive optimal treatment.

Objectives: To document the standard of care that patients hospitalized with HF[1] in Israel received during a 2 month period.

Methods: The Heart Failure Survey in Israel 2003 was a prospective 2 month survey of patients admitted to all 25 public hospitals in Israel with a diagnosis of HF.

Results: The mean age of the 4102 patients was 73 years and 43% were female. The use of angiotensin-converting enzyme/angiotensin receptor blockers and beta blockers both declined from NYHA class I to IV (68.8% to 50.6% for ACE[2]-inhibitor/ARB[3] and 64.1% to 52.9% for beta blockers, P < 0.001 for comparisons). The percentage of patients by NYHA class taking an ACE-inhibitor or ARB and a beta blocker at hospital discharge also declined from NYHA class I to IV (47.5% to 28.8%, P < 0.002 for comparisons). The strongest predictor of being discharged with an ACE-inhibitor or ARB was the use of these medications at hospital admission. Negative predictors for their usage were age, creatinine, disease severity class, and functional status.

Conclusions: Despite the dissemination of guidelines many patients did not receive optimal care for HF. Reasons for this discrepancy need to be identified and modified.
