Does religious observance promote health? mortality in secular vs religious kibbutzim in Israel

OBJECTIVES

This study assessed the association of Jewish religious observance with mortality by comparing religious and secular kibbutzim. These collectives are highly similar in social structure and economic function and are cohesive and supportive communities.

METHODS

In a 16-year (1970 through 1985) historical prospective study of mortality in 11 religious and 11 matched secular kibbutzim in Israel, 268 deaths occurred among 3900 men and women 35 years of age and older during 41347 person-years of observation.

RESULTS

Mortality was considerably higher in secular kibbutzim. Cox proportional hazards analysis was used to adjust for age and the matched design; rate ratios were 1.67 (95% confidence interval [CI]=1.17, 2.39) for men, 2.67 (95% CI=1.55, 4.60) for women, and 1.93 (95% CI=1.44, 2.59) overall. Kaplan-Meier survival analysis of birth cohorts confirmed the association. The lower mortality in religious kibbutzim was consistent for all major causes of death.

CONCLUSIONS

Belonging to a religious collective was associated with a strong protective effect not attributable to confounding by sociodemographic factors. Elucidation of mechanisms mediating this effect may provide etiologic insights and leads for intervention.

The male predominance in the incidence of infectious diseases in children: a postulated explanation for disparities in the literature

In children, a male predominance in the incidence of symptomatic disease has been reported for some infectious agents and not for others. Not only are the factors underlying these sex differences poorly understood, but it is also not clear why the differences are described only for selected infectious diseases. In this study of sex- and age-specific incidence of infectious diseases in children, a possible explanation for the inconsistencies in the literature was explored. The sex ratio in reported disease incidence in Israel during a period of about 20 years was examined for various viral and bacterial infections. In addition, an hypothetical mathematical model was developed which assumes increased susceptibility to infectious disease (such as in relative immune deficiency) in a proportion of males. In children aged under 4 years, a higher incidence among males was consistently observed for all diseases, and the sex ratio varied between 1.16 (95% confidence interval (CI): 1.13-1.18) for shigellosis to 1.98 (95% CI: 1.79-2.17) for viral meningitis. The highest ratios were associated with the diseases which tend to present asymptomatically most often, which is consistent with the predictions of the model. The male excess in symptomatic disease appears to be present for most infectious diseases and this should be taken into account in studies comparing observed disease incidence between groups with different sex ratios. The inconsistencies in reports on the excess male morbidity for infectious diseases may be due to variations in symptomatic to asymptomatic infection ratios.

A study of ethnic, gender and educational differences in attitudes toward COVID-19 vaccines in Israel - implications for vaccination implementation policies

Background

Vaccines for COVID-19 are currently available for the public in Israel. The compliance with vaccination has differed between sectors in Israel and the uptake has been substantially lower in the Arab compared with the Jewish population.

Aim

To assess ethnic and socio-demographic factors in Israel associated with attitudes towards COVID-19 vaccines prior to their introduction.

Methods

A national cross-sectional survey was carried out In Israel during October 2020 using an internet panel of around 100,000 people, supplemented by snowball sampling. A sample of 957 adults aged 30 and over were recruited of whom 606 were Jews (49% males) and 351 were Arabs (38% males).

Results

The sample of Arabs was younger than for the Jewish respondents. Among the men, 27.3% of the Jewish and 23.1% of the Arab respondents wanted to be vaccinated immediately, compared with only 13.6% of Jewish women and 12.0% of Arab women. An affirmative answer to the question as to whether they would refuse the vaccine at any stage was given by 7.7% of Jewish men and 29.9% of Arab men, and 17.2% of Jewish women and 41.0% of Arab women. Higher education was associated with less vaccine hesitancy. In multiple logistic regression analysis, the ethnic and gender differences persisted after controlling for age and education. Other factors associated with vaccine hesitancy were the belief that the government restrictions were too lenient and the frequency of socializing prior to the pandemic.

Conclusions

The study revealed a relatively high percentage reported would be reluctant to get vaccinated, prior to the introduction of the vaccine. This was more marked so for Arabs then Jews, and more so for women within the ethnic groups. While this was not a true random sample, the findings are consistent with the large ethnic differences in compliance with the vaccine, currently encountered and reinforce the policy implications for developing effective communication to increase vaccine adherence. Government policies directed at controlling the pandemic should include sector-specific information campaigns, which are tailored to ensure community engagement, using targeted messages to the suspected vaccine hesitant groups. Government ministries, health service providers and local authorities should join hands with civil society organizations to promote vaccine promotion campaigns.

Epidemiology of inflammatory bowel disease

Epidemiologic studies of inflammatory bowel disease indicate that these disorders occur in susceptible individuals, possibly due to genetic abnormalities, resulting in disturbance of bowel wall function. Environmental factor(s) exerting a primary effect at an early age, in most patients, cause the disease to manifest usually in teenagers or young adults. Secondary environmental factors may alter disease expression, severity, or influence relapse. Studies in identical twins provide the best evidence for the role of genetic factors in the cause of Crohn's disease. Changing trends in disease incidence (seen in many countries) provide strong support for environmental factors as playing a major influence in disease expression. We now require further laboratory and epidemiologic studies in family members at risk of disease, in migrants who move from low incidence areas to high incidence areas, and in area where Crohn's disease particularly is starting to appear. The clinician can play an important role by performing careful observations in patients with a view to uncovering new clues to disease etiology.

Remarkable differences in the epidemiology of pemphigus among two ethnic populations in the same geographic region

BACKGROUND

The epidemiology of pemphigus in different ethnic populations exposed to similar environments is unknown. Trends in the incidence of pemphigus based on an immunopathologically validated cohort have not been investigated.

OBJECTIVES

We sought to estimate the incidence of pemphigus in Israel and to investigate differences between the 2 major ethnic populations.

METHODS

Pemphigus incidence was retrospectively estimated from January 2000 to December 2015 in 2 Israeli regions with a total population of 1.56 million inhabitants.

RESULTS

One hundred eighty patients with pemphigus (mean age, 54.70 ± 16 years) were identified. The overall estimated incidence was 7.2 per million inhabitants per year (95% confidence interval, 6.2-8.3). The incidence in the Jewish population was threefold higher than that in Arabs (9.6 vs 3.2 cases per million per year, respectively; P < .0001) and higher among women than men (9 vs 5.3 cases per million per year, respectively; P < .0001). The incidence decreased from 8.4 cases per million per year in 2000 to 2005 to 7.0 and 6.0 (95% confidence interval, 4.5-7.9) in 2006 to 2010 and 2011 to 2015, respectively (P = .068).

LIMITATIONS

This study was limited by the retrospective design and the small population.

CONCLUSIONS

The incidence of pemphigus in Israel is among the highest reported worldwide and is significantly more frequent among Jews.

What really matters in the social network-mortality association? A multivariate examination among older Jewish-Israelis

The aim of the inquiry was to examine the social network-mortality association within a wider multivariate context that accounts for the effects of background framing forces and psychobiological pathways. The inquiry was based upon the Berkman et al. (2000) conceptual model of the determinants of health. Its main purpose was to identify the salient network correlates of 7-year all cause mortality among Jewish men and women, aged 70 and over, in Israel (n = 1,811). The investigation utilized baseline data from a national household survey of older adults from 1997 that was linked to records from the National Death Registry, updated through 2004. At the time of the study, 38% of the sample had died. Multivariate Cox hazard regressions identified two main network-related components as predictors of survival: contact with friends, a social network interaction variable, and attendance at a synagogue, a social engagement variable. Friendship ties are seen to uniquely reduce mortality risk because they are based on choice in nature, and reflect a sense of personal control. Synagogue attendance is seen to promote survival mainly through its function as a source of communal attachment and, perhaps, as a reflection of spirituality as well. Other possibly network-related correlates of mortality were also noted in the current analysis-the receipt of instrumental support and the state of childlessness.

Twice Silenced: The Underreporting of Child Sexual Abuse in Orthodox Jewish Communities

Child sexual abuse remains an underreported crime throughout the world, despite extensive research and resources dedicated both to improving investigative techniques and helping children disclose their experiences. The discovery of rampant cover-ups within the Catholic Church has exposed some of the ways religious and cultural issues can impede reporting to authorities. This article examines specific factors that contribute to the underreporting of child sexual abuse within Orthodox Jewish communities. It also explores ways in which these communities have handled child sexual abuse reporting in the past and describes recent progress. Implications are offered for CSA prevention, detection, and recovery in Orthodox Jewish communities as well as other minority religious groups.

Religiosity and Fertility: Jews in Israel

We analyze the relationship between religiosity and fertility among Jews in Israel-a modern democracy in which there is no separation of religion and state. Micro-level data from the 2009 Israel Social Survey are used to perform multivariate analyses of the odds of having at least three children. The findings from separate analyses of women and men are consistent with a theoretical framework, outlined by McQuillan and C. Goldscheider, which suggests how religiosity affects fertility. In particular, measures of the importance of religious community explain in part the higher levels of fertility among some religiosity groups; attitudes toward religion as a social and political institution as well as norms regarding family building over the life course also partly account for the influence of religiosity on fertility. While women's employment activity is significantly related to their fertility, as many economic theories predict, controlling for paid work in regression models does not affect the estimated relationship between religiosity and women's fertility. We conclude that, in the current context, fertility variation across religiosity groups can be understood largely in terms of the cultural, political, and institutional power of religion, and the impact of religion through community, and via norms and ideals.

Increased inequality in mortality from road crashes among Arabs and Jews in Israel

OBJECTIVE

Previous studies in several countries have shown that the economically disadvantaged seem to have a greater risk of being involved in a car crash. The aim of the present study was to compare rates and trends in mortality and injury from road crashes by age among the Arab and Jewish populations in Israel.

METHODS

Data on road crashes with casualties (2003-2011) from the Israeli Central Bureau of Statistics were analyzed. Age-adjusted road crash injury rates and mortality rates for 2003 to 2011 were calculated and time trends for each age group and population group are presented. Time trend significance was evaluated by linear regression models.

RESULTS

Arabs in Israel are at increased risk of injury and mortality from road crashes compared to Jews. Road crash injury rates have significantly decreased in both populations over the last decade, although the rates have been persistently higher among Arabs. Road crash mortality rates have also decreased significantly in the Jewish population but not in the Arab population. This implies an increase in the disparity in mortality between Jews and Arabs. The most prominent differences in road crash injury and mortality rates between Arabs and Jews can be observed in young adults and young children.

CONCLUSIONS

The reduction in road crashes in the last decade is a positive achievement. However, the reductions are not equal among Arabs and Jews in Israel. Therefore, an increase in the disparities in mortality from road crashes is apparent. Public health efforts need to focus specifically on decreasing road crashes in the Arab community.

Differentiation of self and trait anxiety: A cross-cultural perspective

Cultural differences are likely to affect the ability to deal with anxiety. We investigated this issue among four cultural groups-Germans and Italians (Europeans living in South Tyrol, Italy), Jews and Arabs (Israelis)-in terms of their levels of differentiation of self, trait anxiety and somatic symptoms. We also examined the relationship of differentiation of self to trait anxiety and somatic symptoms. The sample consisted of 824 students: 387 Israelis (mean age 23.6) and 437 Europeans (mean age 22.3). Israeli participants reported lower levels of trait anxiety than European students. Jewish students reported lower trait anxiety than Arab students (mean difference = -.14, p < .009), while there was no difference between German and Italian students (mean difference = .03, p > .99). Jews reported a significantly lower level of emotional cutoff than Arabs (mean difference = -.45, p < .001), and Germans reported a significantly lower level of emotional reactivity than Italians (mean difference = .29, p < .001). Emotional reactivity and I-position predicted all participants' trait anxiety. On the whole, results point to the importance of examining differentiation of self when trying to reduce trait anxiety, as well as some important cultural differences.

Intergenerational Support and the Emotional Well-being of Older Jews and Arabs in Israel

This investigation examined the cultural context of intergenerational support among older Jewish and Arab parents living in Israel. The authors hypothesized that support from adult children would be more positively consequential for the psychological well-being of Arab parents than of Jewish parents. The data derived from 375 adults age 65 and older living in Israel. Psychological well-being was measured with positive and negative affect subscales of the Positive and Negative Affect Schedule. Overall, positive affect was highest when filial expectations for support were congruent with whether or not instrumental support was received. Findings by cultural background revealed that, among older Jews, receiving instrumental support raised positive affect and stronger filial expectations lowered it. Among older Arabs, receiving financial support raised positive affect and receiving instrumental support lowered it. Culture appears to serve as a potent force in determining which types of intergenerational support functions are expected and accepted means of serving the everyday needs of older parents.

Mortality in two Jewish populations--Montreal and Israel: environmental determinants of differences

BACKGROUND

Mortality was compared in the Jewish populations of Montreal and Israel and the overall Canadian population, to investigate whether the Israeli pattern of low male mortality and relatively high female mortality is replicated among Jews living elsewhere.

METHODS

In Montreal, death certificates were obtained from Jewish funeral homes (where all Jewish deaths are believed to be handled) for 1986-1990 and coded.

RESULTS

All-cause cumulative mortality for ages 35-74 (CM), was exceedingly low in Montreal Jews, both in males (CM = 0.312, 95% confidence interval [CI]: 0.274-0.350) and females (CM = 0.202, 95% CI: 0.172-0.232), compared to all Canadians (CM = 0.425; 95% CI: 0.414-0.435 and 0.251; 95% CI: 0.243-0.253) and Israeli Jews (CM = 0.406; 95% CI: 0.379-0.434, and 0.299; 95% CI: 0.276-0.322), for males and females. Sex ratios (male:female) were 1.36, 1.54, and 1.69 for Israeli Jews, Montreal Jews, and Canadians, respectively. Differences were due mainly to substantially lower cumulative mortality from circulatory diseases in Montreal Jews (CM = 0.139, 0.043 versus 0.203, 0.125 in Israeli Jews and 0.199, 0.081 in Canadians, in males and females, respectively); these differences were all highly significant. Sex ratios for circulatory deaths were lowest in Israel (1.63), highest in Montreal (3.23) and intermediate in Canadians (2.47). Among men, the circulatory diseases mortality ratio for Canadians versus Montreal Jews was 1.43, and 1.46 between Israeli and Montreal Jews; in women, these ratios were 1.87 and 2.90, respectively.

CONCLUSIONS

These findings suggest that the mortality pattern characteristic of Israeli Jews is not a universal Jewish phenomenon and may be affected by modifiable environmental factors. Similar studies conducted in other Jewish communities would aid in confirming these observations.

Change in health behaviours following acute coronary syndrome: Arab-Jewish differences

BACKGROUND

Health-promoting behaviours after acute coronary syndrome (ACS) are effective in preventing recurrence. Ethnicity impacts on such behaviours. We assessed the independent association of Arab vs. Jewish ethnicity with persistence of smoking and physical inactivity 6 months after ACS in central Israel.

DESIGN

Prospective cohort study.

METHODS

During their admission for ACS and subsequently 6 months later, 420 patients were interviewed about their smoking and exercise habits. The association of ethnicity with health-promoting behaviours was assessed by logistic regression adjusting for socio-demographic and clinical covariates.

RESULTS

Smoking prevalence and physical inactivity were substantially higher among Arab patients than Jewish patients at admission (gender-adjusted prevalence rate ratio (RR) 2.25, 95% CI 1.80-2.81, p < 0.01 and RR 1.46, 95% CI 1.28-1.67, p < 0.001, respectively). The relative differences increased at 6 months (RR 2.94, 95% CI 2.13-4.07, p < 0.001 and RR 3.00, 95% CI 2.24-4.04, p < 0.001, respectively). Excess persistent smoking at 6 months among Arab vs. Jewish patients who were smokers at admission (adjusted OR 2.05, 95% CI 1.00-4.20, p = 0.049) was largely mediated through the 3.5-fold higher participation of Jewish patients in cardiac prevention and rehabilitation program (CPRP) (OR adjusted also for CPRP 1.31, 95% CI 0.59-2.93, p = 0.51). Greater persistent sedentary behaviour at 6 months among nonexercisers at admission among Arab patients (adjusted OR 3.68, 95% CI 1.93-7.02, p < 0.001) was partly mediated through attendance of CPRP (OR adjusted also for CPRP 2.38, 95% CI 1.19-4.76, p = 0.014).

CONCLUSIONS

Culturally sensitive programmes need to be developed to enhance CPRP participation and favourable health-promoting changes among Arab patients. A comprehensive understanding of the determinants of the Arab-Jewish differences in efficacious health-promoting behaviours is crucial to inform appropriate ethnic-specific health-promoting strategies.

Arab men who have sex with men in Israel: knowledge, attitudes and sexual practices

OBJECTIVES

Arab men who have sex with men (AMSM) are becoming visible in society, and reports of HIV infection and sexually transmitted infections (STIs) are emerging. This study aimed to assess the knowledge of AMSM regarding HIV transmission, their attitudes towards condom use and their sexual practices compared with Jewish MSM (JMSM), and to evaluate AMSM-JMSM friendships and sexual encounters.

METHODS

Participants in this cross-sectional study completed questionnaires in Arabic or Hebrew. The outcome variable was unprotected anal sex (UAI) in the previous 6 months with a partner(s) whose HIV status was discordant or unknown. AMSM and JMSM indicated if they had friends or sexual encounters from the other ethnic group.

RESULTS

The questionnaires were completed by 342 (16.2%) AMSM and 1775 (83.8%) JMSM in 2012. AMSM were more likely to be religious, 'closeted' and married than JMSM; their knowledge regarding HIV transmission was inferior and attitudes towards condom use were less favourable. AMSM reported less alcohol and drug use than JMSM, were more likely to be attracted to and have sex with women, and reported a greater number of sexual partners and more UAI. Being AMSM was a predictive variable for UAI in the multivariate model. While 178 AMSM (52.0%) reported that most of their close friends were JMSM, 251 (73.4%) had only/mostly sexual encounters with JMSM. Among JMSM, 41 (2.3%) reported that their close friends were AMSM, and 308 (17.3%) had only/mostly sexual encounters with AMSM.

CONCLUSIONS

The knowledge of AMSM regarding HIV transmission and their attitudes towards condom use were less favourable than those of JMSM, and they performed more UAI. AMSM may benefit from targeted interventions, including reconciling their same-sex attraction in positive terms. Same-sex attraction and gay identity may provide common ground to strengthen Arab-Jew communication in Israel.

Do Jews and Arabs Differ in Their Fear of Terrorism and Crime?

The current study was carried out with the aim of supplementing the existing literature and broadening the understanding of the determinants of two powerful types of fear, fear of terrorism and fear of crime, by comparing their presence among Jews and Arabs in Israel. Based on an overview of factors influencing fear of victimization, the study focused on individual variables (ethnicity, sex, age, objective, and subjective exposure) as well as on neighborhood disorder and social integration. The sample consisted of 375 Israeli students (191 Jews and 184 Arabs). Predictions of fear of terrorism and crime were conducted with two multiple regressions. Fear of terrorism was significantly predicted by gender (women more than men), higher self exposure to terror, and higher neighborhood disorder. The only interaction found with regard to exposure to incidents showed that previous victimization predicts only fear of terrorism and only among Arabs who were themselves affected or exposed to the victimization of others. Fear of crime was predicted by sector (Jews more than Arabs), gender (women more than men), higher neighborhood disorder, and lower social integration. As far as known, this is the first attempt to examine differences between Jews and Arabs with regard to these two types of fear and to predict their causes. The findings help gain a better understanding as to how people perceive the threat of crime and terrorism, in general and in the Arab-Jewish context in particular. The findings also enable an understanding of the complexity of living under ongoing terrorism threats. The results are discussed in accordance with the literature, concluding with the need for further research that will take into account the wider cultural and social context.

[Virchow medallists and honorary members of the German Society for Pathology and their relationship with National Socialism : A cross-sectional study. German version]

The present study focuses on the group of pathologists who (1) were appointed honorary members or bearers of the Rudolf Virchow Medal by the German Society for Pathology (DGP) and (2) experienced the "Third Reich" as a citizen of the "Third Reich". In particular, it examines the relationship between those distinguished persons and National Socialism, and, at the same time, the criteria of the professional society when awarding such honours. Specifically, it is important to clarify what role the DGP officials ascribed to the political stance or experience of the candidates in the Nazi dictatorship during the selection process: were there victims of the Nazis among the honourees whose repressive experiences and personal fates were intended to be acknowledged in this way? Of equal interest is the counter-question: were pathologists honoured who had made (party)political commitments to National Socialism during the "Third Reich"?A total of 9 Virchow medallists and 3 honorary members met the inclusion criteria. None of those affected belonged to the group of pathologists who suffered injustice during the "Third Reich" or who could be described as victims of the Nazis. On the other hand, 4 of the 9 German Virchow medal winners and 1 of the 3 honorary members had joined the National Socialist Party and to some extent other Nazi organisations. Obviously, previous closeness to National Socialism was not a decisive factor in the selection of honorary members and Virchow medallists and, in particular, was not an exclusion criterion.The aforementioned results correspond to the findings of a parallel study, in which the political past of the German DGP chairmen appointed up to 1986 was examined. This showed that two thirds of them had joined the National Socialist Party during the "Third Reich".

The Israeli national population program of genetic carrier screening for reproductive purposes. How should it be continued?

The Israeli population genetic screening program for reproductive purposes, is a population-specific screening that includes all known, severe diseases and relatively frequent in a specific population (carrier frequency at or above 1:60 and/or disease frequency at or above 1 in 15,000 live births). The carrier screening program is free of charge and offers testing according to disease frequency in the different groups within the population.

The extraordinary technical changes that occurred in the last decade as well as the changes in the type of marriages within the Israeli population necessitate a revision in the basis of the program.

The screening should include instead of only the relatively frequent variants, all the variants that were reported among patients causing a severe disease for which the natural history is well known without regard of their frequency. The population-specific screening that determine which variants are included according to the origin of the couple should be abandoned for a general screening including either all the Jewish population or all the Israeli Arab population.

Genetic diversity of 38 insertion-deletion polymorphisms in Jewish populations

Population genetic data of 38 non-coding biallelic autosomal indels are reported for 466 individuals, representing six populations with Jewish ancestry (Ashkenazim, Mizrahim, Sephardim, North African, Chuetas and Bragança crypto-Jews). Intra-population diversity and forensic parameters values showed that this set of indels was highly informative for forensic applications in the Jewish populations studied. Genetic distance analysis demonstrated that this set of markers efficiently separates populations from different continents, but does not seem effective for molecular anthropology studies in Mediterranean region. Finally, it is important to highlight that although the genetic distances between Jewish populations were small, significant differences were observed for Chuetas and Bragança Jews, and therefore, specific databases must be used for these populations.

Religious homogamy and marital duration among those who file for divorce in California, 1966-1971

The hypothesis that having a common religion is associated with more stable marriages is tested using California data on divorce for the period 1966-1971. The results confirm the hypothesis, and the authors note that "religious homogamy among Jewish couples is associated with longer [marriage] duration than any other group. Couples who report no religious affiliation appear to be at greatest risk of early filing for divorce. The religious groupings include the Jewish, the Conservative Protestant, the Liberal Protestant, the Roman Catholic and those with no religious affiliation."

The Complexity of Ethnic Identity Among Jewish American Emerging Adults

Jewish Americans may grapple with issues of ethnic identity differently than the larger White American group. Drawn from a large multisite sample (N = 8,501), 280 Jewish American (207 female, 73 male) emerging adults were compared with White American and ethnic minority samples on ethnic and U.S. identity. Jewish Americans rated themselves as significantly higher on measures of ethnic and U.S. identity compared with White Americans but not as highly as ethnic minorities. Ethnic identity search, affirmation, and resolution also predicted higher self-esteem for Jewish Americans, similar to the pattern for other ethnic groups. In addition, ethnic identity search and affirmation moderated the link between perceived discrimination and depressive symptoms among Jewish Americans.

Motivational goals, group identifications, and psychosocial adjustment of returning migrants: The case of Jews returning to Russia

The present study investigated the motivational goals, group identifications, and psychosocial adjustment of Jews who returned to Russia after emigrating from the republics of the Former Soviet Union to different countries (n = 151). To gain a deeper understanding of these returning migrants, their traits were compared with those of Jews living in Russia who did not emigrate (n = 935). Compared to locals, returnees reported a higher preference for the openness to change and self-enhancement values and a lower preference for the conservation values; there was no difference in the self-transcendence values. Returning migrants had a relatively weak affiliation with the home country: they had a weaker identification with the home country than with the country of emigration, their identification with Russians was weaker than that among Jews who did not emigrate from Russia, and their intention to emigrate (again) from Russia was greater than that among locals. However, the Jewish identification of returning migrants was similar to that of locals. The adjustment of returning migrants varied across different dimensions: their economic adjustment was better than that of locals; however, the interpersonal adjustment of returnees was less successful than among locals.

Israeli-born offspring of Jewish immigrants of Middle Eastern origin have a lower incidence of multiple myeloma than those of European origin: a cohort study of 746 200 Israeli men followed from late adolescence

Differences in the prevalence of multiple myeloma across races have been observed, with a two- to three-fold greater prevalence in African Americans compared with Caucasians. Little is known about the incidence or prevalence of multiple myeloma in other populations. The association between father's country of origin and the incidence of multiple myeloma was examined in a nationwide population-based cohort. Health-related data on 746 200 16-19-year-old Jewish males examined between 1967 and 1998 were linked to the Israel National Cancer Registry to derive multiple myeloma incidence up to 2006. During 17 352 349 person-years of follow-up, 109 examinees developed plasma cell dyscrasias. Middle Eastern origin was protective compared to European origin (hazard ratio [HR] 0.39; 95% confidence interval [CI] 0.22-0.68; p = 0.001, adjusted for year of birth), and also when restricted to Israeli-born males (HR 0.44; 95% CI 0.24-0.82; p = 0.01). In conclusion, second-generation adolescents of Middle Eastern origin are at persistently lower risk of developing multiple myeloma compared to those of European origin, supporting a genetic component in the pathogenesis of multiple myeloma.

In Search of the jüdische Typus: A Proposed Benchmark to Test the Genetic Basis of Jewishness Challenges Notions of "Jewish Biomarkers"

The debate as to whether Jewishness is a biological trait inherent from an "authentic" "Jewish type" (jüdische Typus) ancestor or a system of beliefs has been raging for over two centuries. While the accumulated biological and anthropological evidence support the latter argument, recent genetic findings, bolstered by the direct-to-consumer genetic industry, purport to identify Jews or quantify one's Jewishness from genomic data. To test the merit of claims that Jews and non-Jews are genetically distinguishable, we propose a benchmark where genomic data of Jews and non-Jews are hybridized over two generations and the observed and predicted Jewishness of the terminal offspring according to either the Orthodox religious law (Halacha) or the Israeli Law of Return are compared. Members of academia, the public, and 23andMe were invited to use the benchmark to test claims that Jews are genetically distinct from non-Jews. Here, we report the findings from these trials. We also compare the genomic similarity of ∼300 individuals from nearly thirty Afro-Eurasian Jewish communities to a simulated jüdische Typus population. The results are discussed in light of modern trends in the genetics of Jews and related fields and provide a tentative answer to the ageless question "who is a Jew?"

Motorcycle-related head and neck injuries: increased risk among ethnic minorities

Background

Ethnic disparities have been associated with injury and mortality. The impact of ethnicity on head and neck injury (HNI), traumatic brain injury (TBI), in-hospital mortality and resource utilization following a motorcycle crash (MCC) is undetermined. This study explored the influence of ethnicity in these aspects and the effect of helmet use on HNI and TBI following a MCC.

Methods

The National Trauma Registry provided hospitalization data on motorcycle riders and passengers between 2008 and 2017. Ethnicity was classified as Jews or Arabs, the two major ethnic groups in Israel. Univariate followed by multivariable logistic models were applied to examine ethnic disparities. Mediation effect was tested by structural equation modeling.

Results

Among 6073 MCC casualties, Arabs had increased odds of HNI (OR = 1.37,95% CI = 1.12–1.65) and TBI (OR = 1.51,95%CI = 1.12–1.99), and a six-fold decreased odds of helmet use (OR = 0.16,95%CI = 0.12–0.22). The HNI and TBI associations with ethnicity were mediated by helmet use. Arabs had significantly higher odds for admission to intensive care unit (OR = 1.36,95%CI = 1.00–1.83), and lower odds for ambulance evacuation (OR = 0.73,95%CI = 0.61–0.89) and discharge to rehabilitation (OR = 0.55,95%CI = 0.39–0.7). In-hospital mortality was not associated with ethnicity.

Conclusions

Helmet non-use is an important etiologic factor associated with motorcycle-related HNI and TBI among Arabs. While in Israel, ethnic equality exists in in-hospital health care, disparities in ambulance and rehabilitation utilization was found. Intervention programs should target the Arab population and focus on helmet compliance.
