[Mitochondrial DNA polymorphism in populations of the Caspian region and southeastern Europe]

Mitochondrial DNA (mtDNA) restriction polymorphism was examined in Turkmens, Eastern Iranians, and Ukrainians. The gene pools of all populations studied were characterized by the presence of European mtDNA lineages. Mongoloid component observed in Turkmen and Iranian populations with the frequencies of about 20% was represented by groups C, D, and E/G in Turkmens, and by M*, D, A, and B in Iranians. The relative positions of the populations studied, of populations from the Caucasus, Western Iran, and Russian populations from the Krasnodar krai and Belgorod oblast in the space of principal components revealed a geographically specific pattern of the population clustering. The data on mtDNA polymorphism indicated pronounced differentiation of Eastern and Western Iranians. The latter were characterized by a mtDNA group composition similar to that in Eastern Slavs. The historical role of the Caspian populations in the formation of the population of Southeastern Europe is discussed.

[Investigation of monoamine oxidase gene restriction polymorphism in male populations of the Volga-Ural region]

Restriction polymorphism at the monoamine oxidase A (MAO A) gene was typed in eight male populations of the Volga-Ural region (Bashkirs, Chuvashes, Tatars, Udmurts, Maris, Mordovians, Komis, and Russians inhabiting the Republic of Bashkortostan). Analysis of the MAO A alleles frequency distribution patterns did not reveal statistically significant differences between the Volga-Ural populations examined. The results obtained suggest genetic homogeneity of the populations described in respect of the polymorphic locus examined.

[Polymorphism of glutathione S-transferases M1 and T1 in several populations of Russia]

Frequencies of the wild-type and null genotypes of the GSTM1 and GSTT1 genes were established in healthy donors from several Russian populations (ethnic Russians from the towns of Oshevensk and Kholmogory, Arkhangel'sk oblast; ethnic Khants; ethnic Kalmyks; and ethnic Buryats) in order to identify the ethnic group with the maximal frequency of the null genotype. The highest frequency of individuals with the null genotype of both genes was observed in the Kalmyk and Buryat populations. The results may be used to study the effect of climatic and ecological conditions on multifactorial disease incidence in populations.

[Population genetic study of the Alatyr region of the Republic of Chuvashiia]

Population genetic characteristics were estimated in the Alatyr' raion (administrative district) of the Republic of Chuvashia, which has long been populated by three ethnic groups. The ethnic assortativeness values in the town of Alatyr' and the rural area of the district were 1.17 and 1.21, respectively, for Russians; 1.14 and 4.82, respectively, for Chuvashes; and 1.33 and 2.45, respectively, for Mordovians. Wright's statistics were as follows: Fst = 0.00358, Fit = 0.00178, and Fis = 0.00134. The migration indices were 0.0264 for Alatyr' and 0.0178 for the district. The endogamy indices for the total and the Russian populations of Alatyr' were 0.47 and 0.53, respectively. The parameters of isolation by distance were a = 0.000189 and b = 0.00959 for the urban and a = 0.000318 and b = 0.00919 for the rural area. Schemes of the genetic landscape were constructed. The influence of the polyethnic composition on the genetic structure of the population is discussed.

Death, bereavement and traumatic loss in Israel: a historical and cultural perspective

In the present article, we focus on the experience of bereavement and traumatic loss in Israel and examine the main influences that continue to shape them. For the Jewish population the main features are: religious aspects stemming from Jewish tradition and its variants; the secular and contemporary traditions, the ethos of the Israeli state, and the influence of the struggle to reestablish the Jewish people in its homeland. In an increasingly multicultural society, significant changes are occurring. A series of vignettes of grief and mourning illustrate current issues and practices among religious, secular, kibbutz, Russian and Ethiopian segments of society. The remainder of the article discusses emerging patterns of response to bereavement that are socially constructed and historically situated. We follow the variations in these patterns, from shifting forms of memorialization on the collective level to changes in expressive mood on the individual level, which are mediated by the cultural mosaic of the society. Mental health professionals would benefit from an understanding of the multifaceted fabric of beliefs and cultural-specific customs that shape the mourning rituals and their meanings for the bereaved.

Statistics and "sufficiency": toward an intellectual history of Russia's rural crisis

The article examines the impact of the ‘rise of statistical thinking’ and statistical measurement on elite perceptions of the condition of the Russian Empire's post-emancipation peasant economy. Using archival and published sources, it argues that the increased use of statistical measurement did much to concretize in numerical (‘objective’) terms the idea of rural crisis. In particular, the combination of traditional paternalistic concerns about the sufficiency of peasant resources and the use of cadastre measurement yielded an image of the peasant household economy in which the value (the income-producing capabilities) of post-emancipation peasant allotments nearly always fell short of subsistence requirements and tax/payment obligations. Thus, because of how observers measured peasant well-being, it appeared as if peasants had been over-changed for their post-emancipation land allotments and were doomed to exist in a permanent state of crisis.

Immigrants from Chernobyl-affected areas in Israel: the link between health and social adjustment

The concept of cumulative adversity is a useful tool in the study of migration under chronic stress from past traumas. Drawing on this concept, the study explored long-term health and psychosocial effects of past radiation exposure among survivors of the Chernobyl nuclear disaster who immigrated to Israel during the 1990s. Self-rated health status and indicators of social adjustment were compared in two groups of Russian immigrants: 180 persons from Chernobyl-affected areas and 200 immigrants from other areas of the former USSR. The semi-structured questionnaire was administered by Russian-speaking sociology students and analyzed by both quantitative and qualitative methods. In line with earlier research, both the somatic and mental health of Chernobyl survivors were significantly worse than in other immigrants of the same gender and age; a significant share of reported health problems were probably psychosomatic. Depression, sense of stigma and cancer-related anxiety were more prevalent in the study group. Immigrants from contaminated areas tended to use more health services (both conventional and alternative), but were less satisfied with their quality and providers' attitude. The link between perceived health impairment and poorer social accommodation in the host country has been confirmed: Chernobyl-area immigrants experienced more severe occupational downgrading and were more disappointed with the results of their resettlement than other immigrants.

Immigrant and native-born female heroin addicts in Israel

There are an estimated 25,000 heroin addicts in Israel and nearly one out of every five is a woman. Also, about one fourth of the addict population immigrated to Israel from the former Soviet Union (mostly from Russia and the Ukraine) since 1989. In this study, native born and immigrant female addicts were interviewed to develop an understanding of their background characteristics, patterns of drug use, and attitudes based on group status. Results show that the two groups of women are similar in many respects; however, differences do exist. Russian-speaking women tend to be better educated and have a greater concern about their personal health and maintaining custody of their children. Additionally, immigrant women are more inclined to use heroin and other substances while receiving treatment and are more likely to have a father who abuses alcohol. Discussion is given to the study findings as well as issues relevant to the formation of policy regarding services to female addicts in the country.

HLA profile of three ethnic groups living in the North-Western region of Russia

HLA class II alleles were determined by PCR-SSO and PCR-SSP typing of DNA samples from 55 Nentsy, 81 Saami and 73 Pomor individuals from the North-European part of Russia. The results were compared with similar data from Russians. A high frequency of the DRB1*04-DQA1*0301-DQB1*0302 haplotype and a low frequency of the DRB1*11-DQA1*0501-DQB1*0301 haplotype, observed in all three ethnic groups, may indicate a common aboriginal component in their ancestry. Saami and Pomors displayed a similar pattern of allele and haplotype distribution, with the exception of the DRB1*04-DQA1*0304-DQB1*0301 haplotype, which was significantly higher among Saami compared Nentsy, Pomors and Russians. Nentsy individuals had a particularly high frequency of the DRB1*09-DQA1*0301-DQB1*0303 and the DRB1*12-DQA1*0501-DQB1*0301 haplotypes. Genetic distances and correspondence analysis show that Pomors have a close relationship with Norwegians and Finns, whereas Nentsy and Saami are more closely related to Oriental populations.

Colorectal cancer in Russian-speaking Jewish emigrés: community-based screening

OBJECTIVES

Colorectal cancer (CRC) screening by fecal occult blood testing and flexible sigmoidoscopy is recommended by many authorities for those older than age 50. Ashkenazi Jews have been shown to have a higher level of CRC and polyps than the general population. A subset of Ashkenazi Jews, Russian-speaking Jewish immigrants to the United States (RJIs), have not been studied extensively for CRC and may have additional risk factors not found in other Ashkenazi populations.

METHODS

A retrospective chart review was undertaken of fecal occult blood tests, endoscopy reports, and pathology reports of 132 RJIs and 124 non-RJI controls over age 50 between 1987 and 1999 at the Jewish Hospital of Cincinnati Medical Outpatient Clinic.

RESULTS

Mean ages at the time of diagnosis or flexible sigmoidoscopy were 68 yr for RJIs and 66 yr for the non-RJI patients. Of the RJI patients, 38.7% had positive findings: 37 (28.0%) with lesions < 2 cm, five (3.8%) with lesions > 2 cm, and nine (6.8%) with CRC. Of the non-RJI control group patients, 16.9% had positive findings: 16 (12.9%) with lesions < 2 cm, three (2.4%) with lesions > 2 cm, and two (1.6%) with CRC. Age- and sex-matched statistical analysis revealed significantly greater CRC and significantly more polyps > 2 cm for the RJI patients (p < 0.003). This is higher than in other studies of Ashkenazis, which show a 2.3% incidence, and in statistics from the National Cancer Institute, which reveal a national CRC incidence rate for those over age 65 to be 0.30%.

CONCLUSIONS

RJIs in our study have polyps > 2 cm and CRC at a rate of 10.6%, as compared with 4.0% for in-clinic controls and a national average of 0.30% for patients over age 65. This suggests a need for more aggressive screening of this patient population for CRC.

Prevalence of infectious diseases among internationally adopted children

OBJECTIVE

Internationally adopted children are at increased risk of infections acquired in their country of origin. Ongoing surveillance of this unique population is needed to detect changing epidemiology and provide appropriate care.

METHODS

We performed a retrospective cohort study of 504 children adopted from abroad and evaluated from 1997 to 1998 to determine the prevalence of and factors associated with various infectious diseases.

RESULTS

The mean age of the study participants at medical evaluation was 1.6 years; 71% were girls, and they were adopted from 16 countries, including China (48%), Russia (31%), Southeast Asia (8%), Eastern Europe (8%), and Latin America (5%). Overall, 75 (19%) of 404 children tested had tuberculin skin tests >/=10 mm, but all had normal chest radiographs. BCG vaccination (odds ratio [OR]: 7.37; 95% confidence interval [CI]: 3.29, 17.16) and being Russian born (OR: 2.90; 95% CI: 1.68, 5.00) were risk factors for latent tuberculosis infection. Fourteen (2.8%) children had detectable hepatitis B surface antigen, but no child had active hepatitis C, human immunodeficiency virus, or syphilis. Giardia lamblia antigen was detected in 87 (19%) of 461 tested children, and such children were older (mean: 22 months vs 15.5 months) and more likely to have been born in Eastern Europe (OR: 2.82; 95% CI: 1.70, 4.68).

CONCLUSIONS

We demonstrated increased rates of latent tuberculosis infection and G lamblia infection than previously reported. Thus, ongoing surveillance of internationally adopted children, international trends in infectious diseases, and appropriate screening will ensure the long-term health of adopted children as well as their families.

Little orphan Anastasia. The analysis of an adopted Russian girl

It is becoming commonplace for analysts to hear about or encounter in their clinical work adopted children from Korea, China, Eastern Europe, or Russia. There is wide variation in the orphanage experience from one area to another and also in the manner in which the transitional phase from orphanage to adoptive parents is carried out. Not surprisingly, the experience of being an orphan carries with it lifelong implications and repercussions, particularly in the area of self/object relations. Some of the problems of being an orphan are obvious at the time of adoption. Others unfold only in the course of subsequent development. We are increasingly called upon to assist adoptive families whose children are struggling amid much pain and confusion with the aftermath of the threefold experience of becoming an orphan, being raised in an orphanage, and joining a family of another culture. This essay describes in some detail the infancy and early childhood of "Little Orphan Anastasia" as she picks through the emotional rubble of her infancy and samples the embarrassment of rich nurture in her current life with her adoptive parents, the Carters. This is followed by a description of the opening phase of her analysis, in which I sketch some of her attempts to fashion an adapted identity that is more congruent with her life before and after her adoption.

Russian immigrant cardiovascular risk assessment

Immigration from the former Soviet Union has been increasing. In 1990, there were 454,000 Russian immigrants living in the United States. Lifestyle habits prevalent in Russia, including smoking, alcoholism, and little preventive health, are compelling medical and economic reasons to understand the health status of this population. This study identified a cohort of Russian-born subjects living in Denver to characterize their cardiovascular risk profile. Using a risk assessment questionnaire, 204 Russian immigrants were screened. Seventy-one percent had Medicaid insurance; 14 percent were medically indigent. Those aged 55 to 64 years had a higher prevalence of hyperlipidemia (p < 0.04) and hypertension (p < 0.03) than U.S. counterparts; those age 20 to 34 and 65 to 74 years had a higher prevalence of hypertension (p < 0.00001). Almost half of the participants had two or more cardiac risk factors. Cardiac risk factor identification and intervention programs may help to reduce the health care costs for these patients.

Familial factors of blood pressure and adiposity covariation

In the present study, we used the maximum likelihood approach as implemented by variance analysis and attempted to quantify genetic and environmental components of variance in systolic (SBP) and diastolic (DBP) blood pressure in 514 individuals who belonged to a total of 135 nuclear families of Chuvasha, Russia, ethnic origin. The extent to which these interindividual differences depend on age, gender, body mass index (BMI) and other anthropometric measurements was investigated. Major findings include the following. (1) The variation in both SBP and DBP was significantly affected by genetic factors (h(2)(SBP)=0.51+/-0.13, h(2)(DBP)=0.20+/-0.09), shared household environment, and age. These effects were stronger with respect to SBP, which also showed significant gender differences in baseline values and rate of SBP increase with age. (2) Genetic and common household factors, as well as undetected residual effects, were not completely independent. The respective 3 facets of correlation between SBP and DBP were significant: 0.66+/-0.10, 0.76+/-0.11, and 0.55+/-0.14. (3) SBP and DBP each showed significant phenotypic correlations with BMI and anthropometric factors. These correlations had a substantial genetic component but were not equal for SBP and DBP. SBP showed the highest genetic correlation with arm circumference (r(G)=0.63), whereas for DBP, this was found with hip skinfold (r(G=)0.88). (4) Bivariate heritability estimates, as well as adjustment of BP measurements for BMI and selected anthropometrics, indicated that DBP likely does not have independent genetic heritability. The residual genetic variance of adjusted SBP remained significant, although substantially lower in comparison with the nonadjusted h(2).

Diversity of Helicobacter pylori genotypes among Estonian and Russian patients with perforated peptic ulcer, living in Southern Estonia

To compare the genomic variation of Helicobacter pylori in samples obtained from patients with perforated peptic ulcer, living in the same area of Estonia but belonging to different nationalities, 50 non-consecutive patients (32 Estonians and 18 Russians) admitted in the Tartu University Hospital in 1997-1999 were studied. Gastric samples of antral mucosa were obtained during operation and analysed histologically and with PCR for detection of different genotypes of H. pylori (cagA and vacA s and m subtypes). Among the 50 perforated peptic ulcer patients with histologically proven H. pylori colonisation no sample of gastric mucosa showed the s1b subtype of the vacA gene. The perforated peptic ulcer patients were mainly infected with cagA (82%) and s1 (98%) genotypes of H. pylori. The distribution of s1a/m1, s1a/m2 and s2/m2 subtypes of vacA genes was statistically different in Estonian and Russian patients (P<0.05). In conclusion differences in the distribution of vacA s and m subtypes of H. pylori were revealed between Estonian and Russian patients with perforated peptic ulcer from Southern Estonia.
