Mood-Related Drinking Motives Mediate the Familial Association Between Major Depression and Alcohol Dependence

ALCOHOLISM, Issue 8 2009
Kelly C. Young-Wolff
Background:, Major depression and alcohol dependence co-occur within individuals and families to a higher than expected degree. This study investigated whether mood-related drinking motives mediate the association between major depression and alcohol dependence, and what the genetic and environmental bases are for this relationship. Methods:, The sample included 5,181 individuals from the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders, aged 30 and older. Participants completed a clinical interview which assessed lifetime major depression, alcohol dependence, and mood-related drinking motives. Results:, Mood-related drinking motives significantly explained the depression-alcohol dependence relationship at both the phenotypic and familial levels. Results from twin analyses indicated that for both males and females, the familial factors underlying mood-related drinking motives accounted for virtually all of the familial variance that overlaps between depression and alcohol dependence. Conclusions:, The results are consistent with an indirect role for mood-related drinking motives in the etiology of depression and alcohol dependence, and suggest that mood-related drinking motives may be a useful index of vulnerability for these conditions.

Familial association of specific histologic types of ovarian malignancy with other malignancies,

CANCER, Issue 7 2004
Justo Lorenzo Bermejo Ph.D.
Abstract BACKGROUND Population-based data on the familial association of specific histologic types of ovarian malignancy with other malignancies are limited. Such data may help to elucidate etiologic differences among histologic types of ovarian malignancy. METHODS The nationwide Swedish Family-Cancer Database, which includes 10.3 million individuals and 20,974 ovarian carcinomas, was used to calculate standardized incidence ratios and 95% confidence intervals for age- and histology-specific ovarian malignancies in women whose parents or siblings were affected with malignancies at the most common disease sites. RESULTS Ovarian malignancy was found to be associated with ovarian, laryngeal, breast, endometrial, liver, and colon carcinoma, as well as myeloma; epithelial ovarian malignancy was found to be associated with ovarian, endometrial, and skin malignancies and with melanoma and myeloma; papillary serous cystadenocarcinoma was found to be associated with ovarian and skin malignancies and with myeloma; and endometrioid carcinoma was found to be associated with endometrial, ovarian, and prostate malignancies and with melanoma. For younger women (ages 40,45 years) whose mothers were affected with endometrial malignancies, the risk of developing endometrioid carcinoma was slightly greater than the risk of developing papillary serous cystadenocarcinoma. CONCLUSIONS Specific types of ovarian malignancy may be associated with specific familial disease sites, with such associations depending on age at diagnosis; the strength of the observed associations varied according to histology. Associations were found between endometrioid carcinoma and endometrial malignancy and between serous carcinoma and Hodgkin disease. Cancer 2004;100:1507,14. © 2004 American Cancer Society. [source]


Familial associations of intense preoccupations, an empirical factor of the restricted, repetitive behaviors and interests domain of autism

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 8 2009
Christopher J. Smith
Background:, Clinical heterogeneity of autism likely hinders efforts to find genes associated with this complex psychiatric disorder. Some studies have produced promising results by restricting the sample according to the expression of specific familial factors or components of autism. Previous factor analyses of the restricted, repetitive behaviors and interest (RRBI) domain of autism have consistently identified a two-factor model that explains a moderate amount of variance. The identification of additional factors may explain more variance in the RRBI domain and provide an additional component of autism that may help in the identification of underlying genetic association. Methods:, We conducted factor analyses of RRBI symptoms with a sample that included verbal subjects meeting full criteria for autism aged 5 to 22 years (n = 245). Among affected sibling pairs (n = 126) we examined the familial aggregation of the identified factors. We also examined the associations of the factors with autism-related personality traits in fathers and mothers (n = 50). Results:, The previously identified two-factor model , insistence on sameness (IS) and repetitive stereotypic motor behaviors (RSMB) , was replicated in our sample. Next, a second factor analysis that included the item for verbal rituals resulted in a four-factor model , IS, ,simple' RSMB, ,complex' RSMB, and a fourth factor including symptoms associated with intense preoccupations (IP). Of these four, both IS and IP were significantly familial among affected siblings, but only IP was significantly correlated with the broader autism phenotype traits of rigidity and aloofness in fathers. Conclusions:, The results support previous evidence for the IS factor, its familiality, and the identification of IP as an additional strong candidate trait for genetic studies of autism. [source]


Familial associations of rheumatoid arthritis with autoimmune diseases and related conditions

ARTHRITIS & RHEUMATISM, Issue 3 2009
Kari Hemminki
Objective In the era of genome-wide association studies, familial risks are used to estimate disease heritability and the likelihood of candidate-gene identification. This study was undertaken to estimate associations of rheumatoid arthritis (RA) with any of 33 autoimmune diseases and related conditions among parents and offspring, singleton siblings, twins, and spouses. Methods The Multigeneration Register in Sweden was used as a reliable source of information on Swedish families throughout the last century. Data on autoimmune diseases in individual family members were obtained through linkage to the Hospital Discharge Register. The standardized incidence ratio (SIR) was calculated as a measure of the relative risk of RA in family members of patients with RA or any of 33 other autoimmune diseases or related conditions, as compared with the relative risk of RA in those lacking an affected family member. Results Among a total of 447,704 patients, 47,361 were diagnosed as having RA. The SIRs for RA were 3.02 in offspring of affected parents, 4.64 in siblings, 9.31 in multiplex families, 6.48 in twins, and 1.17 in spouses. Significant associations with the familial risk of RA in offspring according to parental proband were observed for ankylosing spondylitis (SIR 2.96), localized scleroderma (SIR 2.40), Sjögren's syndrome (SIR 2.25), systemic lupus erythematosus (SIR 2.13), systemic sclerosis (SIR 1.65), Hashimoto thyroiditis/hypothyroidism (SIR 1.54), pernicious anemia (SIR 1.53), sarcoidosis (SIR 1.40), psoriasis (SIR 1.36), Wegener's granulomatosis (SIR 1.34), and asthma or polymyalgia rheumatica (SIR 1.32). Conclusion This is the first study to compare the familial risks of RA in relation to a large number of autoimmune diseases and related conditions using data from a single population. The high discordant familial risks in this population suggest that there is extensive genetic sharing between RA and the associated diseases. [source]


Sex-specific familial risks of urinary bladder cancer and associated neoplasms in Sweden

INTERNATIONAL JOURNAL OF CANCER, Issue 9 2009
Justo Lorenzo Bermejo
Abstract Male gender and a family history of cancer are established risk factors for urinary bladder neoplasms. This study used the latest update of the Swedish Family-Cancer Database, which includes 42,255 bladder cancer patients, to investigate the sex-specific incidences and types of tumors in relatives of bladder cancer patients. Men with parents or siblings affected by lung cancer did not show an increased risk of bladder neoplasms. Among women, the familial association was restricted to daughters of women with lung cancer. Brothers showed higher risks than the sons of bladder cancer patients. Men older than 54 years were at an increased risk of bladder cancer only if their fathers or siblings were diagnosed after age 65 years. The present data indicated a limited contribution of smoking to the familial clustering of bladder cancer with other neoplasms. The dependence of the relative risks on the type of familial relationship probably reflected a heterogeneous character of familial aggregation. Age-specific results suggested differential risk factors for tumors diagnosed before 50 years of age versus neoplasms detected later in life. The present data may guide the design of forthcoming gene identification studies and the interpretation of the genome-wide association studies that are about to be published. © 2008 Wiley-Liss, Inc.

A case study of familial anti,phospholipid syndrome

INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 5 2002
S. Bhattacharya
Summary Anti-phospholipid syndrome (APS) may have a familial association. In particular, association has been demonstrated between APS and HLA-DR 4, HLA-DR 7 and HLA-DRB1 14 alleles. Here we have described a family sharing the common haplotype of HLA-DR 7 where definite or probable anti,phospholipid syndrome has been identified in six of the seven family members. Apart from the index case, the other family members have demonstrated partial association in spite of sharing the incriminated haplotype. This could be ascribed either to variable penetrance of the involved genes or to the role of an unaccounted for environmental factor. Alternatively, it is possible that the coexistence of the HLA haplotype and the anti-phospholipid antibodies is coincidental. [source]


Donatello's decapitations and the rhetoric of beheading in Medicean Florence*

RENAISSANCE STUDIES, Issue 5 2009
Allie Terry
Abstract While Donatello's bronze sculptures of Judith and David are stylistically discrete, and may have been originally created in and for different contexts, they are firmly connected to one another through their content: both figures clearly are characterized as active agents of decapitation. As this article argues, the Medici fostered a familial association with the iconographic, symbolic and practical language of decapitation in Florence since the Albizzi coup of 1433,4, when the family came to be associated with the feast of St John the Baptist's martyrdom, through the placement of the Donatello sculptures in the family palace in the 1460s. Although rarely mentioned in the vast art-historical literature on the Medici, visual allusions to beheadings in paint, performance and sculpture served a rhetorical function in Florence to describe the shifting political status of Cosimo de'Medici and his family. By outlining a cultural map by which this visual rhetoric of decapitation may be charted in relation to the Medici family, this article contributes yet a further layer of meaning to the Donatello sculptures within the larger context of early Medici patronage and politics and offers a new methodological approach for the investigation of early modern Florentine visual culture.

Neoliberal associations: Property, company, and family in the Argentine oil fields

AMERICAN ETHNOLOGIST, Issue 4 2008
ELANA SHEVER
ABSTRACT The transformation of Argentina's state-owned oil company into a transnational joint-stock corporation and a series of worker-owned subcontracting microenterprises in northwestern Patagonia provides an example of an actually existing neoliberal project. In this article, I illustrate how this project was as much a process of sustaining affective relationality as it was a process of fostering calculative rationality. The privatization process generated corporate subjects attached through familial associations of property, company, and family. Kinship sentiment was also the crucial force that incorporated former state oil workers into the inequitable circuits of the global petroleum industry. I argue that this neoliberal process was effective inasmuch as it worked affectively. [neoliberal, kinship, property, affect, corporations, structural adjustment, petroleum, Argentina] [source]
