Abstract
BACKGROUND The prevalence of type 2 diabetes is increasing rapidly, particularly among younger age groups. Estimates suggest that people with diabetes die, on average, 6 years earlier than people without diabetes. We aimed to provide reliable estimates of the associations between age at diagnosis of diabetes and all-cause mortality, cause-specific mortality, and reductions in life expectancy. METHODS For this observational study, we conducted a combined analysis of individual-participant data from 19 high-income countries using two large-scale data sources: the Emerging Risk Factors Collaboration (96 cohorts, median baseline years 1961-2007, median latest follow-up years 1980-2013) and the UK Biobank (median baseline year 2006, median latest follow-up year 2020). We calculated age-adjusted and sex-adjusted hazard ratios (HRs) for all-cause mortality according to age at diagnosis of diabetes using data from 1 515 718 participants, in whom deaths were recorded during 23·1 million person-years of follow-up. We estimated cumulative survival by applying age-specific HRs to age-specific death rates from 2015 for the USA and the EU. FINDINGS For participants with diabetes, we observed a linear dose-response association between earlier age at diagnosis and higher risk of all-cause mortality compared with participants without diabetes. HRs were 2·69 (95% CI 2·43-2·97) when diagnosed at 30-39 years, 2·26 (2·08-2·45) at 40-49 years, 1·84 (1·72-1·97) at 50-59 years, 1·57 (1·47-1·67) at 60-69 years, and 1·39 (1·29-1·51) at 70 years and older. HRs per decade of earlier diagnosis were similar for men and women. Using death rates from the USA, a 50-year-old individual with diabetes died on average 14 years earlier when diagnosed aged 30 years, 10 years earlier when diagnosed aged 40 years, or 6 years earlier when diagnosed aged 50 years than an individual without diabetes. Using EU death rates, the corresponding estimates were 13, 9, or 5 years earlier. INTERPRETATION Every decade of earlier diagnosis of diabetes was associated with about 3-4 years of lower life expectancy, highlighting the need to develop and implement interventions that prevent or delay the onset of diabetes and to intensify the treatment of risk factors among young adults diagnosed with diabetes.

Abstract
In recent decades, the possibility that use of mobile communicating devices, particularly wireless (mobile and cordless) phones, may increase brain tumour risk, has been a concern, particularly given the considerable increase in their use by young people. MOBI-Kids, a 14-country (Australia, Austria, Canada, France, Germany, Greece, India, Israel, Italy, Japan, Korea, the Netherlands, New Zealand, Spain) case-control study, was conducted to evaluate whether wireless phone use (and particularly resulting exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF)) increases risk of brain tumours in young people. Between 2010 and 2015, the study recruited 899 people with brain tumours aged 10 to 24 years old and 1,910 controls (operated for appendicitis) matched to the cases on date of diagnosis, study region and age. Participation rates were 72% for cases and 54% for controls. The mean ages of cases and controls were 16.5 and 16.6 years, respectively; 57% were males. The vast majority of study participants were wireless phones users, even in the youngest age group, and the study included substantial numbers of long-term (over 10 years) users: 22% overall, 51% in the 20-24-year-olds. Most tumours were of the neuroepithelial type (NBT; n = 671), mainly glioma. The odds ratios (OR) of NBT appeared to decrease with increasing time since start of use of wireless phones, cumulative number of calls and cumulative call time, particularly in the 15-19 years old age group. A decreasing trend in ORs was also observed with increasing estimated cumulative RF specific energy and ELF induced current density at the location of the tumour. Further analyses suggest that the large number of ORs below 1 in this study is unlikely to represent an unknown causal preventive effect of mobile phone exposure: they can be at least partially explained by differential recall by proxies and prodromal symptoms affecting phone use before diagnosis of the cases. We cannot rule out, however, residual confounding from sources we did not measure. Overall, our study provides no evidence of a causal association between wireless phone use and brain tumours in young people. However, the sources of bias summarised above prevent us from ruling out a small increased risk.

Abstract
AIMS The relationship between 1- and 2-h glucose levels following an oral glucose tolerance test (OGTT) and long-term mortality was evaluated. METHODS Over a 33-year period, 2138 individuals were followed for all-cause mortality. Fasting and post-OGTT glucose parameters categorized the cohort according to baseline glycaemic status. Four categories were established according to 1- and 2-h glucose levels (in mmol/l): group A = 1 h ≤ 8.8 and 2 h < 7.8; group B = 1 h > 8.6 and 2 h < 7.8; group C = 1 h ≤ 8.6 and 2 h = 7.8-11.1 (impaired glucose tolerance); group D = 1 h > 8.6 and 2 h = 7.8-11.1 (impaired glucose tolerance). Individuals with diabetes at baseline were excluded from the cohort. RESULTS By August 2013, 51% of the study cohort had died. The worst prognosis occurred in group D (73.8% mortality), followed by groups C (67.5%), B and A (57.9% and 41.6%, respectively). When the 2-h glucose value is 'normal' (< 7.8 mmol/l), the 1-h glucose value > 8.6 mmol/l is an important predictor of mortality (28% increased risk) compared with group A, controlling for sex, age, smoking, BMI, systolic and diastolic blood pressures. A gradual increased hazard for mortality was seen by study group (hazard ratio = 1.28, 1.60 and 1.76, for groups B, C and D, respectively; group A = reference). CONCLUSIONS A 1-h glucose value > 8.6 mmol/l predicts mortality even when the 2-h level is < 7.8 mmol/l. However, when the 2-h level is in the impaired glucose tolerance range, the hazard for mortality rises significantly independent of the 1-h value. Individuals at risk for developing diabetes could be identified earlier using the 1-h threshold value of 8.6 mmol/l, which could avert progression to diabetes and increased mortality..

Abstract
PURPOSE Low self-rated health (SRH) has been found to be associated with increased risk of type 2 diabetes (T2D) and with mortality. We examined the possible interaction between SRH and diabetic state on all-cause mortality in a large cohort of elderly subjects, followed for 14 years. METHODS During the years 2000-2004, survivors of the nationwide longitudinal Israel Study of Glucose Intolerance, Obesity and Hypertension were interviewed and examined for the third follow-up. The 1037 participants (mean age 72.4 ± 7.2 years) were asked to rate their health as: excellent, good, fair, poor, or very poor. Glucose categories were as follows: Normoglycemic, Prediabetes, T2D and Undiagnosed diabetes. Survival time was defined as the time from interview to date of death or date of last vital status follow-up (August 1, 2013). Multivariate Cox proportional hazards models were performed in order to assess whether SRH interacts with glycemic state in the association with mortality. RESULTS A better SRH was reported by those with undiagnosed than known diabetes, and best for normoglycemic and prediabetic individuals. While all individuals with fair or poor/very poor SRH were at increased risk of mortality compared to those with excellent/good SRH, in the known diabetic individuals a greater hazard was observed in the excellent/good SRH (HR 3.32, 95 % CI 1.71-6.47) than in those with fair or poor/very poor SRH (HR 2.19, 95 % CI 1.25-3.86), after adjusting for age, sex, ethnic origin, marital status, education, BMI, physical activity, CVD, tumors, and creatinine level (p for interaction = 0.01). CONCLUSIONS Self-rated health is not a sensitive tool for predicting mortality in elderly men and women with known T2D.

Abstract
BACKGROUND In a preliminary report, we found an association between hyperinsulinemia in the basal (fasting) state and the development of diabetes. OBJECTIVES The current analysis further explored the long term link between basal hyperinsulinemia and conversion to dysglycemia. METHODS This is a prospective study with up to 24 years of follow-up of 515 normoglycemic individuals (mean age at follow up = 70.3 ± 7.0; range 58-94) of an Israeli cohort. Fasting glucose and insulin were measured, and dysglycemia was defined as fasting glucose > 100 mg/dL. RESULTS At the end of the follow-up period, almost half had progressed to dysglycemia. Male sex and elevated baseline levels of basal insulin, body mass index, blood glucose and blood pressure each favoured progression to dysglycemia over the subsequent two decades. A multivariate logistic regression model identified basal hyperinsulinemia as the strongest predictor for progression to dysglycemia (odds ratio = 1.79; 95% confidence interval 1.12-2.88), while controlling for ethnicity, blood pressure, fasting glucose, male sex, body mass index and age. CONCLUSIONS Basal hyperinsulinemia in normoglycemic adults constitutes an independent risk factor for metabolic deterioration to dysglycemia over adulthood, and may help to identify apparently healthy subjects at increased risk for diabetes.

Abstract
AIMS To study the age at presentation and factors associated with adult-onset diabetes (≥ 20 years) among Arabs and Jews in Israel. METHODS Participants (n = 1100) were randomly selected from the urban population of the Hadera District in Israel. The study sample was stratified into equal groups according to sex, ethnicity (Arabs and Jews) and age. Information on age at diabetes presentation, family history of diabetes, history of gestational diabetes, socio-demographic and lifestyle characteristics was obtained through personal interviews. Self reports of diabetes were compared with medical records and were found reliable (κ = 0.87). The risk for diabetes was calculated using Kaplan-Meier survival analysis. Factors associated with diabetes in both ethnic groups were studied using Cox proportional hazard model. RESULTS The prevalence of adult-onset diabetes was 21% among Arabs and 12% among Jews. Arab participants were younger than Jews at diabetes presentation. By the age of 57 years, 25% of Arabs had diagnosed diabetes; the corresponding age among Jews was 68 years, a difference of 11 years (P < 0.001). The greater risk for diabetes among Arabs was independent of lifestyle factors, family history of diabetes and, among women, history of gestational diabetes; adjusted hazard ratio 1.70; 95% confidence interval 1.19-2.43. CONCLUSIONS Arabs in Israel are at greater risk for adult-onset diabetes than Jews and are younger at diabetes presentation. Culturally sensitive interventions aimed at maintaining normal body weight and active lifestyle should be targeted at this population. Possible genetic factors and gene-environmental interactions underlying the high risk for diabetes among Arabs should be investigated.

Abstract
Objectives The objective of this study was to examine the associations of brain tumours with radio frequency (RF) fields from mobile phones. Methods Patients with brain tumour from the Australian, Canadian, French, Israeli and New Zealand components of the Interphone Study, whose tumours were localised by neuroradiologists, were analysed. Controls were matched on age, sex and region and allocated the ‘tumour location’ of their matched case. Analyses included 553 glioma and 676 meningioma cases and 1762 and 1911 controls, respectively. RF dose was estimated as total cumulative specific energy (TCSE; J/kg) absorbed at the tumour's estimated centre taking into account multiple RF exposure determinants. Results ORs with ever having been a regular mobile phone user were 0.93 (95% CI 0.73 to 1.18) for glioma and 0.80 (95% CI 0.66 to 0.96) for meningioma. ORs for glioma were below 1 in the first four quintiles of TCSE but above 1 in the highest quintile, 1.35 (95% CI 0.96 to 1.90). The OR increased with increasing TCSE 7+ years before diagnosis (p-trend 0.01; OR 1.91, 95% CI 1.05 to 3.47 in the highest quintile). A complementary analysis in which 44 glioma and 135 meningioma cases in the most exposed area of the brain were compared with gliomas and meningiomas located elsewhere in the brain showed increased ORs for tumours in the most exposed part of the brain in those with 10+ years of mobile phone use (OR 2.80, 95% CI 1.13 to 6.94 for glioma). Patterns for meningioma were similar, but ORs were lower, many below 1.0. Conclusions There were suggestions of an increased risk of glioma in long-term mobile phone users with high RF exposure and of similar, but apparently much smaller, increases in meningioma risk. The uncertainty of these results requires that they be replicated before a causal interpretation can be made.

Abstract
OBJECTIVES The output power of a mobile phone is directly related to its radiofrequency (RF) electromagnetic field strength, and may theoretically vary substantially in different networks and phone use circumstances due to power control technologies. To improve indices of RF exposure for epidemiological studies, we assessed determinants of mobile phone output power in a multinational study. METHODS More than 500 volunteers in 12 countries used Global System for Mobile communications software-modified phones (GSM SMPs) for approximately 1 month each. The SMPs recorded date, time, and duration of each call, and the frequency band and output power at fixed sampling intervals throughout each call. Questionnaires provided information on the typical circumstances of an individual's phone use. Linear regression models were used to analyse the influence of possible explanatory variables on the average output power and the percentage call time at maximum power for each call. RESULTS Measurements of over 60,000 phone calls showed that the average output power was approximately 50% of the maximum, and that output power varied by a factor of up to 2 to 3 between study centres and network operators. Maximum power was used during a considerable proportion of call time (39% on average). Output power decreased with increasing call duration, but showed little variation in relation to reported frequency of use while in a moving vehicle or inside buildings. Higher output powers for rural compared with urban use of the SMP were observed principally in Sweden where the study covered very sparsely populated areas. CONCLUSIONS Average power levels are substantially higher than the minimum levels theoretically achievable in GSM networks. Exposure indices could be improved by accounting for average power levels of different telecommunications systems. There appears to be little value in gathering information on circumstances of phone use other than use in very sparsely populated regions.

Abstract
BACKGROUND Q waves developed in the subacute and persisting into the chronic phase of myocardial infarction (MI) usually signify myocardial necrosis. However, the mechanism and significance of Q waves that appear very early in the course of acute MI (< 6 h from onset of symptoms), especially if accompanied by ST elevation, are probably different. HYPOTHESIS This study assesses the prognostic implications of abnormal Q waves on admission in 2,370 patients with first acute MI treated with thrombolytic therapy < 6 h of onset of symptoms. RESULTS Patients with abnormal Q waves in > or = 2 leads with ST-segment elevation (n = 923) were older than patients without early Q waves (n = 1,447) (60.6 +/- 11.9 vs. 58.8 +/- 11.9 years, respectively; p = 0.0003), and had a greater incidence of hypertension (34.3 vs. 30.5%; p = 0.05) and anterior MI (60.6 vs. 41.1%; p < 0.0001). Time from onset of symptoms to therapy was longer in patients with Q waves upon admission (208 +/- 196 vs. 183 +/- 230 min; p = 0.01). Peak serum creatine kinase (2235 +/- 1544 vs. 1622 +/- 1536 IU; p < 0.0001), prevalence of heart failure during hospitalization (13.8 vs. 7.0%, p < 0.0002), hospital mortality (8.0 vs. 4.6%; p = 0.02), and cardiac mortality (6.6 vs. 4.5%, p = 0.11) were higher in patients with anterior MI and with abnormal Q waves than in those without abnormal Q waves upon admission. There was no difference in peak creatine kinase, prevalence of heart failure, in-hospital mortality, and cardiac mortality between patients with and without abnormal Q waves in inferior MI. Multivariate regression analysis confirmed that mortality is independently associated with presence of Q waves on admission (odds ratio 1.61; 95% CI 1.04-2.49; p = 0.04 for all patients; odds ratio 1.65; 95% CI 0.97-2.83; p = 0.09 for anterior wall MI. CONCLUSION Abnormal Q waves on the admission electrocardiogram (ECG) are associated with higher peak creatine kinase, higher prevalence of heart failure, and increased mortality in patients with anterior MI. Abnormal Q waves on the admission ECG of patients with inferior MI are not associated with adverse prognosis.

Abstract
BACKGROUND In order to allot an ovarian malignancy to FIGO Stage I, in addition to abdominal exploration and the basic operation, it is also necessary to do peritoneal washings for cytological examination, random peritoneal biopsies (including diaphragmatic assessment) and omental and retroperitoneal lymph node assessment. OBJECTIVE The aim of the study was to assess the accuracy of surgical staging of ovarian carcinoma classified as Stage I in Israel. METHODS Included were all patients with histologically confirmed epithelial ovarian carcinoma (EOC) classified as Stage I in a data base of a nationwide incidence case control epidemiological study of ovarian carcinoma conducted in Israeli Jewish women during the period 1994-1999. Surgical staging data of these patients were retrieved from pathological reports, and from clinical records when available. RESULTS A total of 182 EOC patients were classified as Stage I. About 86% of the patients underwent hysterectomy and bilateral salpingo-oophorectomy. The most commonly performed staging procedure was omental assessment (85.2%) while peritoneal biopsy was the least common one (34.1%). In 17 (9.3%) of the patients none of the staging procedures were done and only 34 (18.7%) had optimal staging. CONCLUSION Although the data are from a decade ago, they seem to indicate the need for an increased awareness of the necessity for accurate surgical staging of tumors apparently confined to the ovaries since it can identify a group of patients who require surgical therapy alone and who can be spared the complications, inconvenience and cost of adjuvant chemotherapy.

Abstract
Many long-term prospective studies have reported on associations of cardiovascular diseases with circulating lipid markers and/or inflammatory markers. Studies have not, however, generally been designed to provide reliable estimates under different circumstances and to correct for within-person variability. The Emerging Risk Factors Collaboration has established a central database on over 1.1 million participants from 104 prospective population-based studies, in which subsets have information on lipid and inflammatory markers, other characteristics, as well as major cardiovascular morbidity and cause-specific mortality. Information on repeat measurements on relevant characteristics has been collected in approximately 340,000 participants to enable estimation of and correction for within-person variability. Re-analysis of individual data will yield up to approximately 69,000 incident fatal or nonfatal first ever major cardiovascular outcomes recorded during about 11.7 million person years at risk. The primary analyses will involve age-specific regression models in people without known baseline cardiovascular disease in relation to fatal or nonfatal first ever coronary heart disease outcomes. This initiative will characterize more precisely and in greater detail than has previously been possible the shape and strength of the age- and sex-specific associations of several lipid and inflammatory markers with incident coronary heart disease outcomes (and, secondarily, with other incident cardiovascular outcomes) under a wide range of circumstances. It will, therefore, help to determine to what extent such associations are independent from possible confounding factors and to what extent such markers (separately and in combination) provide incremental predictive value.

Abstract
Family history (FH) scores are used for estimating the familial risk (FR), i.e. the level of risk for a particular disease among members of that family. An FH score is created from reports about the disease status of the relatives in each family. The most commonly used score is the dichotomous score (positive when at least one relative is affected), which does not consider the family size, number of affected relatives nor each relative's risk factor profile. Authors have proposed many other FH scores that overcome these deficiencies by using external expected risks adjusted for important risk factors. We consider the use of FH scores in studies, which investigate risk factors for a disease and where family risk is considered as a confounder, and examine through simulations the performance of a variety of FH scores in controlling the FR status. We also examine performance in predicting true FR status. For both criteria, only small differences were found between most of the FH scores, although the dichotomous score performed the poorest. Since the proportion score (the proportion of first-degree relatives of the index who have the disease) is the simplest to calculate, use of this score seems to be justified.

Abstract
AIM To validate short term recall of mobile phone use within Interphone, an international collaborative case control study of tumours of the brain, acoustic nerve, and salivary glands related to mobile telephone use. METHODS Mobile phone use of 672 volunteers in 11 countries was recorded by operators or through the use of software modified phones, and compared to use recalled six months later using the Interphone study questionnaire. Agreement between recalled and actual phone use was analysed using both categorical and continuous measures of number and duration of phone calls. RESULTS Correlations between recalled and actual phone use were moderate to high (ranging from 0.5 to 0.8 across countries) and of the same order for number and duration of calls. The kappa statistic demonstrated fair to moderate agreement for both number and duration of calls (weighted kappa ranging from 0.20 to 0.60 across countries). On average, subjects underestimated the number of calls per month (geometric mean ratio of recalled to actual = 0.92, 95% CI 0.85 to 0.99), whereas duration of calls was overestimated (geometric mean ratio = 1.42, 95% CI 1.29 to 1.56). The ratio of recalled to actual use increased with level of use, showing underestimation in light users and overestimation in heavy users. There was substantial heterogeneity in this ratio between countries. Inter-individual variation was also large, and increased with level of use. CONCLUSIONS Volunteer subjects recalled their recent phone use with moderate systematic error and substantial random error. This large random error can be expected to reduce the power of the Interphone study to detect an increase in risk of brain, acoustic nerve, and parotid gland tumours with increasing mobile phone use, if one exists.

Abstract
OBJECTIVE To characterize the factors contributing to a greater than 10 year delay in the diagnosis of familial Mediterranean fever (FMF). METHODS 50 patients, in whom diagnosis of FMF was delayed by more than 10 years, comprised the study population. The clinical, demographic and molecular genetic characteristics were compared to a control group of 50 FMF patients, in whom the diagnosis was made within a reasonable time period (less than 5 years from onset). Additional factors contributing to a delayed diagnosis in the study group, including physician-related factors, patient-related factors, disease-factors and other factors, were studied as well. RESULTS Overall, attack sites, duration and severity were comparable among study and control groups. No differences in ethnic origin or family history of FMF were noted between the groups. There were significantly more females (p = 0.009), newly-arrived immigrants (p = 0.005) and carriers of unidentified MEFV mutations (p = 0.04) in the study group. Delayed diagnosis of FMF stemmed from misdiagnosis and physician negligence (70%), as well as from patient negligence (70%). The diagnosis was ultimately made mainly due to a change in disease pattern and other causes, such as diagnosis of FMF in a relative. CONCLUSION The study unveils unexpected causes behind a prolonged delay in the diagnosis of FMF such as social status (immigrant), female gender, physician negligence and lack of patient awareness. The possibility that the delay stems from a milder disease pattern was dismissed.

Abstract
OBJECTIVE To analyze the somatic pattern of p53 expression and BRCA germline mutation status in Israeli patients with both ovarian (OvCa) and breast cancer (BrCa). METHODS The study group comprised 43 Israeli patients with OvCa, all of whom had previous primary BrCa. p53 immunohistochemistry (IHC) on all available archival tissues and genotyping for the three predominant Jewish germline BRCA1-2 mutations were carried out. Samples from 64 patients with solitary OvCa and 61 with solitary BrCa were similarly analyzed as controls. RESULTS p53 expression pattern and the immunopositivity rate were similar in the ovarian and breast tumors within the study group and in the two control groups: positive p53 staining was detected in 68% of ovarian tumors in the study group compared with 71.9% in the controls, and in 19.4% of the BrCa tissues versus 21.3% in the controls. Within the study group, advanced stage OvCa had a higher rate of p53 expression (84%) compared to early stage disease (38.5%) (P = 0.006). This difference was not apparent in the solitary OvCa control group. OvCa in BRCA1-2 mutation carriers from the study group were more likely to display positive p53 staining (79%), especially in tumors diagnosed before the age of 60 (90%) compared with the OvCa of noncarriers (60%), but this difference was statistically insignificant. The p53 expression rate in BrCa samples from the study group was not associated with BRCA1-2 mutation status. CONCLUSIONS Positive p53 expression, detected by IHC, in OvCa patients with previous primary BrCa is significantly higher in advanced stage disease in BRCA1-2 mutation carriers. There is a higher positive p53 expression somatically in OvCa in BRCA1-2 carriers in whom OvCa was diagnosed before the age of 60 years, although this trend is not statistically significant. These observations suggest that somatic p53 inactivation may be an important event in ovarian tumorigenesis in this subset of patients.

Abstract
This study was undertaken in order to evaluate a possible genetic influence on the pathogenesis of ovarian dermoid cysts. We have performed a case-control study comparing the prevalence of a history of dermoid cysts in first-degree relatives of women with dermoid cysts and among first-degree relatives of women without dermoid cysts. The study group included 285 women with an established diagnosis of ovarian dermoid cysts. The control group included 378 women with sonographically normal ovaries. To assess the relationship between a first-degree family history of dermoid cysts and the diagnosis of ovarian dermoid cysts, a multivariate stepwise logistic regression model was applied. In 28 families of the study group (9.8%), a dermoid cyst was found in at least 1 first-degree relative as compared with only eight families (2%) among the controls (adjusted odds ratio -5.60; 95% CI 2.24-14.2). The data suggest a genetic predisposition towards dermoid cysts which merits further exploration.

Abstract
OBJECTIVE The objective was to evaluate the prevalence of BRCA1/2 mutations in selected categories of ovarian cancer patients in Israel. METHODS Blood samples and specimens of ovarian tumors were obtained in the course of a national case control study of women with ovarian cancer in Israel. Eight hundred ninety-six patients with epithelial ovarian cancer, 40 cases with nonepithelial ovarian cancer, and 68 with primary peritoneal cancer were tested for the BRCA mutations. Analysis of the three common BRCA mutations in Israel (185delAG, 5382insC in BRCA1, and 6174delT in BRCA2) was done using a multiplex polymerase chain reaction assay. A multivariate logistic regression model was used to assess the association of mutation carrier status and other factors (age, origin, family history, and clinical variables). RESULTS Of the 779 invasive epithelial ovarian cancer cases, 29.4% were mutation carriers. The prevalence of the mutations was higher among women below age 60 and in more advanced cases. The prevalence was low in mucinous tumors. There was almost a twofold excess of mutations among women with positive family history (45.7%), but still 26.5% of the family history negative cases were carriers. As expected, we found a higher rate of mutation carriers among the Ashkenazi group (34.2%) and 55% among Ashkenazi women with positive family history. No subjects born in North Africa were mutation positive. CONCLUSION BRCA mutations are strongly associated with ovarian cancer and they are present in variable rates in distinct age, ethnic, and histopathologic categories.

Abstract
During the years 1994-1999, a nationwide ovarian cancer case-control study was conducted in Israel. The present analysis addresses the question: Is epithelial ovarian cancer associated with body mass index at age 18 years and/or with weight changes in body mass index between adolescence and adult life? The study is based on 1,269 women with epithelial ovarian cancer and 2,111 matched controls. A significant decrease in risk of ovarian cancer was observed with parity, oral contraceptive use, and postmenopausal status. A significant increase in risk with family history of ovarian/breast cancer was also found. No significant association with age at menarche or infertility was found. For body mass index at age 18 years, the odds ratio of the highest versus lowest body mass index quartile was 1.42 (95% confidence interval: 1.08, 1.85) and after adjusting for confounders was 1.54 (95% confidence interval: 1.17, 2.02). However, no statistically significant risk associated with change in weight from age 18 years to adult life was found. The authors conclude that, in their population, body mass index at age 18 years is an independent risk factor for ovarian cancer.

Abstract
The objective of this paper is to assess whether ovarian hyperstimulation and in vitro fertilization (IVF) are associated with increased risk of cancer development, using an historical cohort analysis of infertile women who attended the IVF unit, Lis Maternity Hospital Tel Aviv Medical Center, Tel Aviv, Israel. One thousand and 82 women participated in the IVF treatment program between 1984 and 1992. Cancer incidence rates were determined through the National Cancer Registry and were compared to the expected rates with respect to appropriate age and continent of birth. Twenty-one cases of cancer were observed as compared to 11 that were expected (SIR 1.91; 95% CI 1.18–2.91). When cancer cases that were diagnosed within one year of the IVF treatment were excluded from the analysis (SIR = 1.46; 95% CI 0.83–2.36), no significant excess risk of cancer was noted. We conclude that in this cohort of infertile women, the higher than expected cancer rate could not be attributed to IVF treatments. Special attention should be made to women who may be diagnosed with cancer during or shortly after IVF treatment.

Abstract
OBJECTIVE The aim of the present study was to compare demographic and clinical characteristics of primary peritoneal carcinoma (PPC) to ovarian carcinoma (OvC) with regard to BRCA mutation frequencies. METHODS Incident cases of histologically confirmed cancer of the ovary or peritoneum diagnosed in Israeli Jewish women between March 1, 1994, and June 30, 1999, were identified within the framework of an ongoing nationwide epidemiological study of these neoplasms in Israel. The present study comprises 609 (81.5% of 747) Jewish women with epithelial stage III-IV OvC and 68 (77.3% of 88) Jewish women with PPC who were genetically tested for the BRCA mutations. Data from each patient were collected by the aid of a prestructured questionnaire and medical records. Blood samples or tumor tissue was tested for the 185delAG and 5382insC mutations in BRCA1 and the 6174delT mutations in BRCA2. RESULTS A carrier rate of 28% of any BRCA 1/2 mutation was observed among the PPC group and of 30% among the invasive stage III-IV OvC. No differences were found between PPC and OvC neither in the overall distribution of BRCA1/2 mutation carrier rates nor according to type of mutation, age, ethnic origin, and histologic subtype. Among women with a positive family history, a higher rate of mutation carriers was observed in the PPC group compared to the OvC group (72.7 vs 43.8%, respectively, P = 0.07). CONCLUSIONS The similar frequency distribution of BRCA1/2 mutations in PPC and OvC observed in the present study indicates that these mutations may predispose to PPC as well and that this neoplasm is part of the hereditary breast-ovarian cancer syndrome.

Abstract
OBJECTIVES Using a theoretical framework that divided social factors measures into structure, function, and social engagement, this study determined those aspects of social networks most significantly associated with 8-year, all-cause mortality among the old-old in Israel. METHODS Jews (n = 1,340) aged 75-94 living in Israel on January 1, 1989, were randomly selected from the National Population Register; stratified by age, sex, and place of birth; and interviewed in person. Mortality was determined according to the National Death Registry (December 1997). RESULTS After controlling for sociodemographics and measures of health, cognitive status, depressive symptoms, and physical function, the measures of social engagement that explicitly involved others were associated with a lower risk of mortality. No measure of the function of the social network was associated with risk of mortality. Living in the community without a spouse and with a child and living in an institution were significantly associated with a higher risk of mortality. DISCUSSION The finding that participating in activities with people outside of the immediate family is associated with a lower risk of death has practical implications for helping the aging population and their families in their decision-making process. Lack of support for the hypothesis that those with more social support would show reduced risk of mortality may indicate that the positive effect of perceiving support and the negative effect of needing support may cancel each other out and result in no perceived effect. In this population, the association between socioeconomic status (SES) and the risk of mortality seems to be expressed through the living arrangements, with the sick and frail, both in institutions (higher SES) and in the community with a child or other (lower SES), having a higher risk of mortality. These findings are consistent with the use of children as a substitute for institutionalization, and imply that at least some cohabitation was the caretaking solution for the noninstitutionalized old-old who were of low SES, frail, and close to death.

Abstract
PURPOSE To study the role of BRCA mutations in ovarian cancer survival. PATIENTS AND METHODS Blood samples and specimens of ovarian tumors (whenever blood samples were not available) at the time of the primary surgery were obtained in the course of a nationwide case-control study of women with ovarian cancer in Israel. The three common BRCA mutations in Israel (185delAG, 5382insC, and 6174delT) were analyzed with a multiplex polymerase chain reaction to amplify the exons containing the three mutations using fluor-labeled primers in a single reaction. Because each mutation is a small insertion or deletion, they can be detected as length polymorphisms. Patients were followed for up to 5 years (range, 20 to 64 months). Statistical analysis was performed using the Kaplan-Meier method and the log-rank test. Stepwise Cox regression analysis was used for determination of independent prognostic factors. RESULTS This report is based on 896 blood or tumor specimens analyzed for the presence of the BRCA mutations. Of these, 234 women (26.1%) were found to be positive. A significant difference in survival pattern was found between BRCA1/BRCA2 carriers and noncarriers among the women with invasive ovarian cancer (median survival, 53.4 months v. 37.8 months; 3-year survival, 65.8% v. 51.9%, respectively). These differences were independent of age at diagnosis or stage of the disease. CONCLUSION Our data indicate that the survival of patients with ovarian cancer is affected by BRCA germline mutation, at least in the early years after diagnosis.

Abstract
To date, there is no data regarding the association of patient in-hospital referral source and stroke rehabilitation outcomes. The objective of the present study was to investigate the possible relation between in-hospital referring source, whether directly from an emergency ward (EW) or indirectly through a general medical ward (GMW), and the functional outcomes achieved during rehabilitation of such stroke patients. This retrospective observational study included 315 consecutive patients, admitted for rehabilitation following the onset of acute stroke. We compared those referred directly to us from the EW, with others referred from GMWs. Functional status was assessed by Functional Independence Measure method (FIM). Functional outcome was determined by total FIM gain (efficacy) and daily FIM gain (efficiency), both absolute and relative (to potential). The two study groups were similar in terms of age, gender, and diagnosis. FIM admission scores were higher at admission in patients admitted directly from the EW, compared with those referred from GMWs (72.5 +/- 27.5 and 62.7 +/- 25.6, respectively) but similar at discharge (77.4 +/- 28.8 and 80.7 +/- 32.5, respectively). Length of stay (LOS) in the GMW group was longer as compared to the EW group. Efficacy was significantly associated with being married, younger age, hemiplegia, and admission scores between 40-60. Both absolute and relative efficacy and efficiency rates of rehabilitation were significantly lower among patients referred from the EW. We conclude that in-hospital referral source is associated with different rehabilitation outcomes in stroke patients. Direct admission of stroke patients from the EW is associated with lower rehabilitation efficacy and efficiency rates, compared with those admitted from GMWs. The findings support the implementation of different selection methods, underscoring the need of both clinicians and administrators to consider the in-hospital referral source as a potential factor associated with stroke rehabilitation outcome.

Abstract
BACKGROUND AND PURPOSE Although risk factors for carotid artery stenosis caused by atherosclerosis are known, it is unclear what triggers "activation" of the atherosclerotic plaques and the ensuing thromboembolic cerebral events. The aim of this study was to evaluate whether thrombophilic factors, platelet glycoprotein (GP) polymorphisms, and homocysteine are associated with a risk of ischemic events in patients with significant carotid stenosis. METHODS Consecutive patients with >/=50% carotid stenosis, whether symptomatic (with ipsilateral ischemic events) or asymptomatic, who were evaluated and followed in a neurovascular clinic were tested for plasma levels of homocysteine, C677T mutation in methylenetetrahydrofolate reductase, G20210A mutation of factor II, factor V Leiden, antiphospholipid antibodies, and polymorphisms of platelet membrane GP: human platelet antigen (HPA)-1, GP Ia (C807T), and GP Ib (variable number of tandem repeats, Kozak, and HPA-2). RESULTS Eighty-six asymptomatic and 67 symptomatic patients were evaluated. The former group was older (73.7+/-6.9 versus 69.5+/-9.1 years, P=0.02). Major risk factors for stroke were similar in both groups. In symptomatic patients versus asymptomatic patients, hyperhomocysteinemia was 3-fold more frequent (34.3% versus 12.8%, respectively; P=0.002) and HPA-1a/b was almost 2-fold more common (38.8% versus 20.9%, respectively; P=0.01). All other thrombophilic factors and platelet polymorphisms studied did not differ significantly between the 2 groups. Multivariate analysis revealed that hyperhomocysteinemia and the HPA-1a/b genotype conferred a significant risk of cerebral ischemic events, with odds ratios (95% CI) of 4.07 (1.7 to 9.7) and 3.4 (1.5 to 7.8), respectively. CONCLUSIONS Hyperhomocysteinemia and HPA-1a/b are independent risk factors for ischemic events in patients with significant carotid stenosis.

Abstract
RAD51 colocalizes with both BRCA1 and BRCA2, and genetic variants in RAD51 would be candidate BRCA1/2 modifiers. We searched for RAD51 polymorphisms by sequencing 20 individuals. We compared the polymorphism allele frequencies between female BRCA1/2 mutation carriers with and without breast or ovarian cancer and between population-based ovarian cancer cases with BRCA1/2 mutations to cases and controls without mutations. We discovered two single nucleotide polymorphisms (SNPs) at positions 135 g-->c and 172 g-->t of the 5' untranslated region. In an initial group of BRCA1/2 mutation carriers, 14 (21%) of 67 breast cancer cases carried a "c" allele at RAD51:135 g-->c, whereas 8 (7%) of 119 women without breast cancer carried this allele. In a second set of 466 mutation carriers from three centers, the association of RAD51:135 g-->c with breast cancer risk was not confirmed. Analyses restricted to the 216 BRCA2 mutation carriers, however, showed a statistically significant association of the 135 "c" allele with the risk of breast cancer (adjusted odds ratio, 3.2; 95% confidence limit, 1.4-40). BRCA1/2 mutation carriers with ovarian cancer were only about one half as likely to carry the RAD51:135 g-->c SNP. Analysis of the RAD51:135 g-->c SNP in 738 subjects from an Israeli ovarian cancer case-control study was consistent with a lower risk of ovarian cancer among BRCA1/2 mutation carriers with the "c" allele. We have identified a RAD51 5' untranslated region SNP that may be associated with an increased risk of breast cancer and a lower risk of ovarian cancer among BRCA2 mutation carriers. The biochemical basis of this risk modifier is currently unknown.

Abstract
BACKGROUND Endometrial carcinoma is considered a hormonal-dependent tumor; estrogen induces endometrial cellular proliferation, whereas progestins display an antiproliferative effect on endometrial tissue. The role that androgen and its receptor (androgen receptor [AR]) play in the pathogenesis of endometrial carcinoma is less clear. Although androgen has an in vitro inhibitory effect on endometrial cell proliferation, up to 75% of endometrial carcinoma express AR somatically. A polymorphic CAG repeat within exon 1 of the AR encodes for a polyglutamine tract, with length range of 8 to 33 repeats, which is inversely correlated with the transcriptional activity of the AR. METHODS To gain insight into the role of AR in endometrial carcinoma, the authors analyzed the polymorphic CAG repeat in 79 Jewish Israeli patients with endometrial carcinoma as compared with 44 healthy Jewish women serving as controls. Analysis was conducted using germline DNA as template and using polymerase chain reaction primers flanking the CAG repeat with subsequent fluorescent determination of allele sizes. RESULTS Allele size range of the longer of the two alleles in the patients was 11-33 (mean, 19.8 +/- 2.7) and in the controls 10-22 (mean, 17.9 +/- 1.9), a statistically significant difference (P < 0.01). Allele size variation within the patient group did not correlate with disease stage, grade, reproductive history, or age at diagnosis. CONCLUSIONS The authors conclude that AR-CAG repeat length differs in Jewish patients with endometrial carcinoma as compared with healthy individuals in Israel, and this finding increases the possibility that the AR is involved in the predisposition to this neoplasm.

Abstract
BACKGROUND Multiparity and the use of oral contraceptives reduce the risk of ovarian cancer, but their effects on this risk in women with a BRCA1 or BRCA2 mutation are unclear. METHODS We conducted a population-based case-control study of ovarian cancer among Jewish women in Israel. Women were tested for the two founder mutations in BRCA1 and the one founder mutation in BRCA2 that are known to be common among Jews. We estimated the effects of parity and oral-contraceptive use on the risk of ovarian cancer in carriers and noncarriers in separate analyses that included all control women, who did not have ovarian cancer. RESULTS Of 751 controls who underwent mutation analysis, 13 (1.7 percent) had a BRCA1 or BRCA2 mutation, whereas 244 of 840 women with ovarian cancer (29.0 percent) had a BRCA1 or BRCA2 mutation. Overall, each additional birth and each additional year of use of oral contraceptives were found to lower the risk of ovarian cancer, as expected. Additional births were protective in separate analyses of carriers and noncarriers, but oral-contraceptive use appeared to reduce the risk only in noncarriers; among carriers, the reduction in the odds of ovarian cancer was 12 percent per birth (95 percent confidence interval, 2.3 to 21 percent) and 0.2 percent per year of oral-contraceptive use (-4.9 to 5.0 percent). CONCLUSIONS The risk of ovarian cancer among carriers of a BRCA1 or BRCA2 mutation decreases with each birth but not with increased duration of use of oral contraceptives. These data suggest that it is premature to use oral contraceptives for the chemoprevention of ovarian cancer in carriers of such mutations.

Abstract
Background: In Jewish individuals of Ashkenazi (East European) decent, three predominant mutations, 185 delAG and 5382insC (BRCA1) and 6174delT (BRCA2), seem to account for a substantial portion of germline mutations in high-risk breast/ovarian cancer families. Among non-Ashkenazi Jews, the 185delAG and the Tyr978X mutations, as well as several 'private' mutations have been reported within the BRCA1 gene. Objective: Assessing the occurrence rate of the Tyr978X BRCA1 germline mutation in Jewish non-Ashkenazi individuals: high-risk familial cases, unselected ovarian cancer patients and the general average risk Jewish Iraqi population. In addition, finding proof that this is a founder mutation. Methods: PCR amplification of the relevant fragment of the BRCA1 gene from constitutional DNA followed by restriction enzyme digest that differentiates the wild type from the mutant allele. In addition, BRCA1-linked markers were used for haplotype analysis. Results: The Tyr978X BRCA1 mutation was detected in 3/289 (1%) of the average-risk Jewish Iraqi population, in 7/408 (1.7%) high-risk Jewish non-Ashkenazi individuals (representing 332 unrelated families) and in 1/81 (1.2%) of unselected Jewish non-Ashkenazi ovarian cancer patients. Allelotyping using BRCA1-linked markers revealed an identical allelic pattern in all mutation carriers with the intragenic markers. Conclusions: Our findings suggest that this mutation is prevalent in Iraqi Jews, represents a founder mutation, and should be incorporated into the panel of mutations analyzed in high-risk families of the appropriate ethnic background.

Abstract
OBJECTIVES The objective of this paper is to assess the risk factors for physician contact in the month before the interview (PM) and emergency room utilization (ERU) and overnight hospitalization (OH) in the year before the interview, through the use of the behavioral model as a conceptual framework. DESIGN A random stratified sample of subjects age 75 to 94 was selected from the National Population Register (a complete listing of the Israeli population maintained by the Ministry of the Interior). The study sample consisted of Jews living in Israel on January 1, 1989, stratified by age (four 5-year age groups: 75-79, 80-84, 85-89, and 90-94), sex, and place of birth (Europe/America, Asia/Africa, and Israel). SETTING Community-dwelling old-old Jewish Israelis. PARTICIPANTS 1,487 people living in the community at the time of the baseline interview. MEASUREMENTS The dependent variables were PM in the month before the interview and ERU and OH in the previous year. The independent variables were: predisposing variables (age, sex, place of birth, and education); enabling variables (income and the social network variables of marital status, living arrangements, and number of in-person contacts per week with any child); and need variables (number of self-reported chronic medical conditions, subjective health, depressive symptoms, number of difficulties with activities of daily living and instrumental activities of daily living, measures of physical robustness, and engaging in regular physical sportive activities). RESULTS The predisposing and enabling factors were only minimally associated with utilization rates in the old old in Israel, with the exception of lower rates of ERU by those who were living alone. Age was not significantly associated with healthcare utilization in the old-old population studied. Healthcare utilization was found to be associated primarily with health and functional status. CONCLUSION In a system of free and equal access to healthcare services, the demand for health services by a population with high levels of chronic disease and disability is driven primarily by health needs, rather than by extraneous factors such as income and education. The study indicates that equity in the provision of health services is attainable. Policy makers should provide for actual need, remove artificial barriers, and prepare accurate estimates of future needs.

Abstract
To assess factors affecting parental relinquishment of infants with Down syndrome, we conducted a nationwide cohort study of infants with Down syndrome who were born in Israel during 1979-1983 and 1987-1991. Overall relinquishment rate was 25%. Major factors affecting relinquishment were mother's age, birth order, infant's health status, and study periods. A decision to relinquish a newborn infant in the hospital is probably based on a combination of several parameters, such as the economic status of the family, social mores, and religious beliefs.

Abstract
Acute lymphoblastic leukemia (ALL) is a malignant disease whose incidence is relatively low among adults, unlike in children. Adults with ALL have a lower rate of long-term disease-free survival. During the last 20 years, a German multicenter group has shown that their protocols have achieved good results in adults ALL. We reviewed the medical records of 35 ALL patients, aged 19-63 years, whom we treated with these protocols (1988-1997). The remission rate was 94%. At a median follow-up of 46 months the 2-year overall survival was 54% and the disease-free survival was 94%. Although 2 patients died of bone marrow transplant complications, no death was directly associated with drug toxicity. The main grade 3 or 4 side effects (WHO classification) were neutropenia (91%), thrombocytopenia (71%) and anemia (71%). With there protocols we achieved high overall and disease-free survival rates, especially in comparison with other reports. Despite the high rate of severe treatment toxicity, there were no fatalities directly related to treatment. These results emphasize the need to concentrate treatment of adult ALL patients in large medical centers with expertise in the use of the complicated treatment protocols required.

Abstract
OBJECTIVE The aim of this study was to define the prevalence, clinical characteristics, and BRCA1-2 mutation carrier status of ovarian cancer (OvC) patients with a previous primary malignancy in the breast (PPMBr). METHODS The study population comprised 1240 consecutive Jewish Israeli women with pathologically confirmed epithelial OvC diagnosed between March 1, 1994, and December 31, 1997. Demographic and clinical data were obtained from medical files and from a detailed questionnaire taken through a nationwide epidemiological case-control study on OvC. Blood samples and tumor tissues were collected for analysis of the three predominant germline BRCA1-2 Jewish founder mutations (185delAG, 5382insC, and 6174delT). RESULTS Fifty nine (4.7%) patients with OvC had a PPMBr. The median age at diagnosis of OvC was 60 years. The mean interval between the two diagnoses was 104 months (range 0-363 months). In the majority of the patients (n = 53), the diagnosis of breast cancer (BrC) preceded the OvC by more than 1 year. The ovarian tumors were diagnosed in 47% of the cases following investigation of patients' symptoms. In 41%, diagnosis was made as a consequence of check-up exams performed during the routine follow-up of BrC survivors. Patients with PPMBr were more likely to present with FIGO ovarian stage III-IV, compared to women with solitary OvC (73% vs 60. 3%, P < 0.05), and less likely to have borderline tumors (3.4% vs 17. 9%, P = 0.007). Family history of OvC/BrC was recorded in 26% of this group of patients compared to 10.5% among patients with solitary OvC (P = 0.003). Patients with PPMBr had an exceptionally high prevalence of BRCA1-2 mutations (57%), irrespective of family history. CONCLUSIONS Patients with PPMBr present with more advanced disease and invasive-type epithelial ovarian tumors when compared to cases associated with solitary OvC. The rate of BRCA1-2 mutations in Jewish women with OvC who had PPMBr is at least twice as high as in Jewish women with OvC as the solitary disease.

Abstract
In this study, a method of taking one blood pressure reading using a sphygmomanometer was compared with a method of taking multiple successive readings using an automatic device. With multiple readings the blood pressure tended to be lower and fewer patients were classified as hypertensive. Using an automatic blood pressure recording device seems to be a practical way of achieving multiple readings in a busy clinic setting.

Abstract
OBJECTIVE To investigate whether polymorphic p53 and WAF1 alleles are associated with clinical, demographic and histopathological features and BRCA mutation in women with ovarian cancer. DESIGN A cross-sectional study. POPULATION Two hundred and twenty-one nonselected Israeli women with epithelial ovarian cancer. METHODS DNA was analysed for known polymorphisms in intron 3 (a 16 nucleotide single repeat) and intron 6 (a G to A change at nucleotide 13,494) of the p53 gene, the S31R polymorphism in the WAF1 gene, and for three predominant Jewish mutations in the BRCA genes (185delAG and 5382insC in BRCA1, and 6174delT in BRCA2). MAIN OUTCOME MEASURE The rate of polymorphic p53 and WAF1 alleles and their association with BRCA mutation, ethnic origin, age and stage at diagnosis, and family history of cancer. RESULTS Of the tested women, 72 (32.6%) were either BRCA1 (n = 57) or BRCA2 (n = 15) mutation carriers. Sixty-eight of 213 (31.9%) were heterozygous for intron 3 polymorphism, 67/193 (34.7%) for intron 6 polymorphism, and 22/154 (14.3%) for S31R of the WAF1 gene. The p53 and WAF1 polymorphism rate did not differ between BRCA mutation carriers and noncarriers. No significant association between specific p53 or WAF1 genotypes, and clinical, histopathological or demographic variables was observed. CONCLUSION In Jewish-Israeli women with sporadic and familial ovarian cancer, p53 or WAF1 polymorphisms do not seem to affect the phenotype.

Abstract
BACKGROUND The possible association between ovarian carcinoma and ovulation-inducing drugs has led to renewed interest in the potential carcinogenic risks of these drugs. In vitro fertilization (IVF) has been linked to multiple pregnancies and possibly congenital malformations. However, to the authors' knowledge the association between IVF and pediatric cancer has been described only in sporadic case reports. The aim of this study was to assess the incidence rate of pediatric cancer among a cohort of children born after IVF. METHODS A historic prospective study based on a cohort of 332 children from 1254 women who underwent IVF treatment between 1981-1994 was performed. Medical files were reviewed and names were linked to the National Population and Cancer Registries. Pediatric cancer incidence rates were compared with the expected age-adjusted rates of the general population during the respective time period. RESULTS No cancer cases were observed among the study cohort with respect to 1.7 cases that were expected. CONCLUSIONS Because the small cohort analysis in the current study lacked the necessary power to reach definite conclusions, larger prospective studies are needed to assess the potential carcinogenic effect on children born after ovulation induction and IVF.

Abstract
We assessed the prognostic significance of negative T waves on admission in leads with ST elevation in 2,853 patients with acute myocardial infarction treated with thrombolysis. Patients were classified into 2 groups based on the presence of negative (T-) or positive (T+) T waves in the leads with ST elevation on admission. T+ and T- waves on admission were detected in 2,601 (91%) and 252 (9%) patients, respectively. T- waves were observed in 6.7 and 9.6% of patients admitted </=2 and 2-6 h after onset of infarction, respectively. There was a difference in prognosis between patients admitted </=2 and >2 h after symptom onset. T- patients admitted </=2 h after onset had no hospital mortality (0/52 patients), as compared to a 5.0% mortality rate in T+ patients (36/726 patients; p = 0.19). T- patients treated >2 h after onset suffered higher mortality (20/196 patients; 10.2%) than T+ patients (100/1,836 patients; 5.4%; p = 0.01). Multivariate analysis of the data on patients treated >2 h after onset demonstrated T- waves to be associated with mortality (OR 1.86; 95% CI 1.07-3.25; p = 0.017). T- waves in leads with ST elevation upon admission are associated with adverse prognosis in patients presenting >2 h after symptom onset, whereas in patients presenting </=2 h after first symptoms, T- waves may be associated with better prognosis.

Abstract
A single germ line mutation in BRCA1, (185delAG) is detected in a substantial portion of Jewish Israeli patients with ovarian cancer. Whether disease phenotypes differ in BRCA1 mutation carriers and sporadic cases is presently a subject for debate. To gain insight into this issue, we analysed tumours from 65 Jewish women with ovarian cancer, 29 (45%) were 185delAG BRCA1 mutation carriers, and 36 (55%) were non-carriers of any of the predominant Jewish mutations in BRCA1 or BRCA2 (sporadic). In 19/29 mutation carriers (66%) diagnosis was made prior to age 60 years, compared with 14/36 (39%) of the non-carriers (P=0.03; Yates corrected P=0.06). Low malignant potential ('borderline') tumours were detected less frequently among carriers (2/29; 7%) than non-carriers (9/36; 25%) (P=0.03; one tail P=0.05). Immunohistochemical analysis in invasive carcinoma (n=54) showed that 17/27 carriers (63%) and 18/27 non-carriers (67%) had positive nuclear staining with a p53 antibody. In 4/27 carriers (15%) and 3/25 non-carriers (12%), 25% or more of the tumour cells stained positive for Ki-67, an insignificant difference. Results were not altered by including borderline tumours (n=11) in these analyses. We conclude that the rate of TP53 inactivation and proliferative index in ovarian cancer, are similar for 185delAG BRCA1 mutation carriers and sporadic cases.

Abstract
Our aim was to evaluate the role of maternal nutritional habits during the period of gestation and of children subsequent diet in the etiology of pediatric brain tumors. All cases of incident nervous system tumors under age 18, diagnosed between 1984 and 1993 (n = 300) in Israel were identified. Two matched population controls per case were selected (n = 574). Personal interviews, using a semi-quantified three-step food frequency questionnaire, were performed. Univariate analysis showed that increased child consumption of vegetable fat [p trend 0.01; 95% confidence interval (CI) 1.1-3.2], carbohydrates (p trend 0.05; CI 1.0-5.9), and vitamin E (p trend 0.05; CI 1.0-3.3), were significantly associated with brain tumor risk. No associations were found with nitrate, nitrite or vitamin C. A significant positive association with potassium consumption (p trend 0.01; CI 1.1-3.7) was noted during gestation. Results of multivariate analysis showed that the only persisting associations were with vegetable fat (OR = 1.36; CI 1.06-1.73) in the child diet and potassium intake during gestation (OR = 1.44; CI 1.04-1.99). In conclusion, nutritional associations with pediatric brain tumor etiology, remain unsubstantiated.

Abstract
Head irradiation, the acceptable mode of treatment for tinea capitis in the past, is recognized today as a causative factor for meningioma. This treatment was applied en mass to immigrants coming to Israel from North Africa and the Middle East during the 1950s. In order to estimate the effect of the differential radiation treatment on the rates of meningioma in the total population, the authors assessed time trends of this disease in Israel over the past 40 years by main ethnic origin. Cohort analysis shows a marked incidence rise in the North African-born cohorts born in 1940-1954 starting from the 1980s. A similar pattern is seen in the Middle Eastern born, although the increase is not as sharp. In consequence, there is a crossover of the interethnic incidence curves in the 1940-1949 cohort. Comparison of the relative risk between 1940-1954 cohorts that comprised most of the irradiated with 1930-1939 cohorts, who were largely free of the radiation, shows that the North African born have the largest relative risk of 4.62, followed by the Middle Eastern born, with a relative risk of 1.95, while the European-American born have a relative risk close to 1. The differences between the three areas of birth are statistically significant. The data illustrate the potential risk of administering highly potent therapy for an essentially benign disease that led, in turn, to a drastic change in the national meningioma pattern.

Abstract
This study evaluated the prognostic significance of reinfarction location by considering the previous site or type of myocardial infarction (MI) among 1601 patients with a history of previous MI who took part in the International (non-Italian) tPA/STK trial and/or the Israeli GUSTO study population. These patients were accordingly divided and hospital mortality was compared by six location groups as follows: acute inferior with previous inferior (8.1% hospital mortality), acute inferior with previous anterior (12.8%), acute anterior with previous inferior (13.3%), acute anterior with previous anterior (11.1%), acute inferior with previous non-Q-wave MI (7.6%), and acute anterior with previous non-Q-wave MI (11.2%) (p = 0.17 for comparison between the six groups). Hospital mortality tended to increase among patients with an anterior reinfarction compared with those with an inferior one (12.1% vs. 9.5%, p = 0.12). Among patients with a reinfarction at a different ECG location from the previous event, mortality tended to be higher compared with patients with two MIs at the same location (13.1% vs. 9.7%, p = 0.07). Recurrent MI following a previous Q-wave MI did not cause a higher mortality compared with a previous non-Q-wave type of MI (11.5% vs. 9.5%, p = 0.24). Among patients sustaining reinfarction, overall mortality did not differ between STK- and tPA-treated patients (11.0% vs. 11.4%, p = NS). In conclusion, the current study identified trends for higher mortality rates in patients with anterior compared with inferior reinfarction, with remote compared with the same ECG location of the two infarctions but not following a previous non-Q-wave compared with Q-wave MI. However, no particular combination of successive MIs location was significantly associated with a higher risk for hospital mortality.

Abstract
The aim of this study was to assess risk factors for the excessive infant mortality rates (IMR) of infants with Down's syndrome (DS). The study population included all 847 Jewish DS births in Israel during 1979-83 and 1987-91. Cases were identified through the National DS Registry. Data were abstracted from hospitalisation records. Ninety-one per cent of the DS diagnoses were confirmed by a cytogenetic analysis. The DS IMR were 24.3 times higher than in the general population. Major risk factors affecting DS IMRs were health status, time period of birth and residential arrangement of the infant. Other known risk factors for infant mortality, such as young maternal age, high birth order and low birthweight, had a weaker impact on IMR in the DS population. Our results imply that the current better survival of infants with DS is a function of the changing attitude towards this population. The study identifies a potential for further reduction in the mortality rates of DS infants, provided there is willingness to adopt a more active and supportive treatment and further changes in ethical codes of the public.

Abstract
The structure and function of social networks and the perceived instrumental and emotional support associated with these networks were studied longitudinally among a random sample of 687 Jewish Israelis aged seventy-five to ninety-four, stratified by five-year age groups, place of birth (Europe-America, Asia-Africa, or Israel), and gender, interviewed in 1989-92 and 1993-94. Perceived instrumental support at follow-up was predicted by baseline measures of proximity of at least one child and by four or more weekly contacts with intimate friends or family, whereas perceived emotional support was more broadly based and was predicted by more frequent contacts with children, neighborliness, and having more intimate friends. Changes occurring during the follow-up interval, such as entering long-term care or losing a confidant, were associated with a decrease in perceived emotional support but not with a loss of instrumental support. Emotional support was less replaceable over time than was instrumental support.
