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.
 

Quantitative chimerism testing has become an indispensable tool for following the course and success of allogeneic hematopoietic stem cell transplants. In this paper, we describe the current laboratory approach to quantitative chimerism testing based on an analysis of short tandem repeats, and explain why performing this analysis longitudinally is important and feasible. Longitudinal analysis focuses on relative changes appearing in the course of sequential samples, and as such exploits the ultimate potential of this intrinsically semi-quantitative platform. Such an analysis is more informative than single static values, less likely to be confused with platform artifacts, and is individualized to the particular patient. It is particularly useful with non-myeloablative conditioning, where mixed chimerism is common. When longitudinal chimerism analysis is performed on lineage-specific subpopulations, the sensitivity, specificity and mechanistic implications of the data are augmented. Importantly, longitudinal monitoring is a routinely feasible laboratory option because multiplex STR-PCR[1] kits are available commercially, and modern software can be used to perform computation, reliability testing, and longitudinal tracking in a rapid, easy to use format. The ChimerTrack© application, a shareware program developed in our laboratory for this purpose, produces a report that automatically summarizes and illustrates the quantitative temporal course of the patient’s chimeric status. Such a longitudinal perspective enhances the value of quantitative chimerism monitoring for decisions regarding immunomodulatory post-transplant therapy. This information also provides unique insights into the biological dynamics of engraftment underlying the fluctuations in the temporal course of a patient’s chimeric status.

Eponyms are titles of medical disorders named for individuals who originally described the condition. They also help us remember and identify the disorder. Medicine is replete with them, and changing them or eradicating them, for whatever reason, is not simple. But when there is a moral issue involved – for example, the research conducted under overwhelming unethical conditions – we believe it wrong to perpetuate and thus “reward” the memory of the individual for whom the disorder is named. The name of a syndrome should thus be discontinued if described by an individual whose research used extreme or who was involved in atrocities against humanity. Ethical considerations should be introduced into medical nosology just as they exist in patient care and research. This article details a group of notable eponyms, the names of which are associated with overt crimes of the medical community during the Nazi era, and provides alternative medical nomenclature. In addition, examples are provided of eponyms named after Nazi era victims, eponyms of those who protested such injustices, and eponyms of those who had to flee discrimination and death. These should be remembered and even strengthened, as opposed to those of the perpetrators, which should be obliterated. Since the greatest accolade a physician can earn is praise from his colleagues as expressed in an eponym entrenched in one's name, the medical profession should remove any honor given to physicians involved in crimes to humanity.

Background: The association between antibiotic use in the community and antimicrobial resistance is known. Attention has recently focused on the type of agents being prescribed.

Objectives: To implement, evaluate and compare the efficacy of two community interventions programs – continuous versus seasonal medical education – oriented to primary care physicians with emphasis on appropriate use of antimicrobial drugs.

Methods: From October 2000 to April 2003 we conducted two interventions: a) a monthly educational campaign in selected clinics promoting appropriate diagnosis of common infectious diseases and prudent antibiotic use (continuous intervention group); and b) a massive educational campaign, conducted before two consecutive winters, promoting the judicious use of antibiotics for treating respiratory infections (continuous intervention group and seasonal intervention group). Sixteen similar clinics were randomized (8 to each group). The total antibiotic use was measured as defined daily dose/1000 patients/day, and compared between the groups. 

Results: The total use of antibiotics decreased between 1999-2000 and 2002-2003 in both groups, but slightly more significantly in the continuous intervention group. The DDD/1000 patients/day for the seasonal group in 1999-2000 was 27.8 vs. 23.2 in 2002-2003; and for the continuous group 28.7 in 1999-2000 vs. 22.9 in 2002-2003, a reduction of 16.5% and 20.0% respectively (p<0.0001). The main change in antibiotic use was noted for broad-spectrum antibiotics.

Conclusions: We present a successful community intervention program aimed to reduce unnecessary antibiotic use. Amplification of this type of intervention is imperative to stop the increase in antimicrobial resistance.
 

Objectives: To describe how an HMO[1] used its health information technology in a way that enables its management to receive updated online information on the demands of the insured, according to their distribution throughout the country during the time of the war in Lebanon in July-August 2006.

Methods: Data were derived from the computerized medical records of Maccabi Healthcare Services – the second largest HMO in Israel, providing care to more than 1.7 million members nationwide. Data on healthcare utilization by northern members were compared to the geographic distribution of clinics.

Results: The war was characterized by the massive evacuation of citizens southwards. During this period there was an abrupt decline in the utilization of medical services by northern members in the northern region. This decline returned to normal 10 days after the ceasefire. A reciprocal increase was noted in the use of health services by citizens from the north in other regions. This increase returned to normal after the war. No such pattern was noticed during the same period in 2005.

Conclusions: Real-time surveillance of trends in consumption of health services by citizens in times of regular daily living as well as during emergencies and wars is a vital management tool for medical directors responsible for providing health services.

Background: Anti-influenza vaccination has proven cost-effective for society. In Israel, however, vaccination rates remain relatively low in comparison to other countries.

Objectives: To analyze the socioeconomic and health status factors affecting the decision to be vaccinated against flu and to compare these factors to results from other countries in order to determine which segments of the adult population should be targeted for increased coverage in influenza vaccination programs.

Methods: Our source was the 1999/2000 Health Survey of the Central Bureau of Statistics for the group aged 25 and above, comprising 16,033 individuals. We used statistical methods such as the Probit regression model to estimate the effects of socioeconomic and health status variables on the decision to get a flu shot. The variables included gender, age, marital status, education, ethnic origin, religious affiliation and housing density, as well as chronic illnesses, smoking, hospitalizations, membership in health management organizations and kibbutz membership.

Results: Our findings indicate that being a post-1990 immigrant from the former Soviet Union, living in a densely populated house, being unmarried and smoking heavily are important factors in predicting the decision not to be vaccinated. In contrast, chronic illness, previous hospitalizations, older age, and kibbutz membership have a positive effect on the decision to take the vaccine.

Conclusions: It is necessary to identify the socioeconomic and health variables marking population sectors that are less likely to be vaccinated in order to design a suitable policy to encourage vaccination.

Objectives: To estimate usual patterns of acute illness in the community as a baseline for integration into pandemic influenza and bioterrorism preparedness plans.

Methods: Between 2000 and 2003 we conducted 13 telephone surveys to estimate the usual incidence and prevalence of symptoms of acute illness in the community.

Results: On average, 910 households were included in each of the surveys, representing about 3000 people. The compliance rates for full interviews ranged from 72.3% to 86.0%. In winter, on average, about 2% of the Israeli population (individuals) suffered each day from fever of ≥ 38ºC, and about 0.8% during the other months. The prevalence of cough was higher, 9.2% in winter and 3% during summer. Daily incidence of fever ranged from about 0.4% per day in winter to about 0.2% in the fall. The prevalence and incidence of both fever and cough were highest for infants followed by children aged 1–5 years.

Conclusions: These background morbidity estimates can be used for planning the overall treatment requirements, in addition to actual cases, resulting from pandemic influenza or a bioterrorist incident.

Objectives: To determine whether drug studies in the pulmonary/allergy literature also demonstrate a publication bias towards more favorable results when a pharmaceutical company funds the study.

Methods: We reviewed all original articles published in seven pulmonary and allergy journals between October 2002 and September 2003. Included in the review were studies of inhaled corticosteroids (oral or nasal), long- or short-acting bronchodilators, or leukotriene receptor antagonists. Articles with funding from a pharmaceutical company and/or one or more authors employed by a pharmaceutical company were considered pharmaceutical company-sponsored studies. The remaining studies were considered not sponsored by a pharmaceutical company. Results were compared to ascertain whether positive results were obtained more frequently in the company-sponsored studies.

Results: Of the 100 articles included in this review 63 were considered pharmaceutical company-sponsored research. Results favorable for the drugs studies were significantly more common in those funded by a pharmaceutical company (98% vs. 32%).

Conclusions: In the pulmonary and allergy literature, as in other fields, there is a publication bias towards positive results in pharmaceutical company-sponsored research.
