Human papillomavirus and cervical intraepithelial neoplasia grade III/carcinoma in situ: a case-control study in Spain and Colombia.

A case-control study of 525 cases of cervical intraepithelial neoplasia grade III (CIN III) and 512 controls was conducted in Spain and Colombia between 1985 and 1988 to assess the role of human papillomavirus (HPV) in the etiology of CIN III. HPV DNA in cytological scrapes from the cervix was assessed by Virapap and by polymerase chain reaction (PCR) based on the L1 consensus primers. A subsample of 268 specimens was also tested for HPV DNA using Southern hybridization. In Spain, the PCR-based prevalences of HPV DNA were 70.7% among cases and 4.7% among controls. Odds ratio (OR) and 95% confidence interval (numbers in parentheses) for HPV DNA were 56.9 (24.8-130.6). In Columbia HPV DNA was detected by PCR in 63.2% of the cases and in 10.5% of the controls. The OR was 15.5 (8.2-29.4). The estimated fractions of CIN III attributable to HPV were 72.4% in Spain and 60.3% in Colombia. HPV 16 was the predominant viral type and showed the strongest association with CIN III; in Spain the OR was 295.5 (44.8-1946.4) and in Colombia the OR was 27.1 (10.6-69.5). HPV DNA of unknown type was frequent in HPV-positive cases (18.3% in Spain and 38.0% in Colombia) and controls (66.7% in Spain and 47.4% in Colombia). The comparison of results from Virapap and PCR indicated that PCR is the method of choice for epidemiological studies. These data strongly support the hypothesis of the viral origin of CIN III, the common etiology of CIN III and invasive cervical cancer, and the causal nature of the association between HPV and CIN III.

[Reproductive or domestic work]. / El trabajo reproductivo o doméstico.

The objective of this article is to describe the evolution of reproductive work and to analyse those factors related to its distribution. The analysis has been based on data from various Time-use Surveys (Women Institute 1993, 1996, 2001) as well as on data from different regional surveys: Andalusia, the Basque Country, Madrid and the metropolitan area of Barcelona. In the period 1993-2001, the amount of time devoted by men to housekeeping in Spain increased by 35% while women's time declined by 5%. Yet, in 2001 women's dedication to housekeeping was twice that of men's (7.2 vs 3.1 h daily). However, the imbalance in sharing of housework declined among younger people. Union formation and growing family size increase women's housework intensifying the uneven distribution of household chores. When women are employed and have higher educational and income levels, dedication to household tasks decreases and gender inequalities are reduced. In spite of growing male participation in housework, reproductive work is still mainly women's responsibility. The recent legal, social and cultural changes have not been able to eradicate the traditional model of assigning reproductive work in the home.

Socioeconomic position and type 2 diabetes mellitus in Europe 1999-2009: a panorama of inequalities.

The aim of the present review is to synthesis findings from studies on the relationship between socioeconomic position (SEP) and incidence, prevalence and mortality of type 2 diabetes mellitus (T2DM) in Europe between the years 1999 and 2009. A systematic search was carried out in the National Library of Medicine's PubMed database. The search was limited to articles published between January 1999 and December 2009, in English or Spanish. Additional requirements for inclusion were: (i) presentation of empirical results directly related with SEP and the prevalence, incidence or mortality of diabetes, (ii) dealing with T2DM, (iii) carried out in Europe, and (iv) mainly focused only on diabetes. Of the 19 articles found, twelve studied the relationship between SEP and the prevalence of T2DM, two dealt with diabetes incidence, three with mortality and two studied both inequalities in mortality and prevalence. People with more deprived SEP have greater incidence, more prevalence and higher mortality due to T2DM, although the magnitude and significance of the associations varied from one study to another. Part of these inequalities is explained by SEP differences in the prevalence of the established T2DM risk factors. SEP inequalities in T2DM tended to be greater in women than in men. There is consistent evidence that SEP inequalities in T2DM incidence, prevalence and mortality are present in Europe, especially among women. Improving accessibility of physical activity in terms of both price and availability, access to healthy food, and access to health services, will be key to achieving a reduction of SEP related diabetes inequalities in Europe.

Socio-economic inequalities in the prevalence of Type 2 diabetes, cardiovascular risk factors and chronic diabetic complications in the Basque Country, Spain.

AIMS: To establish the relationship between socio-economic status and the prevalence of known Type 2 diabetes, cardiovascular risk factors and chronic diabetic complications. METHODS: In 2000, a cross-sectional survey was conducted among 61 general practitioners (GPs) who studied 65 651 people older than 24 years. Of those, 2985 known Type 2 diabetic patients were registered. The main outcome measures were: diabetes prevalence, major cardiovascular risk factors, chronic diabetic complications and primary care services utilization in Type 2 diabetic patients. Socio-economic status was based on area-based socio-economic measures. RESULTS: The prevalence of known Type 2 diabetes was higher in patients of lower socio-economic status (OR: 2.17, 95% CI: 1.77-2.28), especially among women (OR: 2.28, 95% CI: 1.91-2.73). In Type 2 diabetes patients, obesity, sedentary lifestyle, and abnormal levels of low-density lipoprotein (LDL) cholesterol and HbA(1c) were more prevalent among those from lower socio-economic status. Macroangiopathy was inversely associated with socio-economic status after adjustment for clinical and demographic variables. Patients of lower socio-economic status more frequently visited primary care services than those of higher status. CONCLUSIONS: This study shows an association between deprivation and Type 2 diabetes prevalence, cardiovascular risk factors and chronic diabetic complications in Type 2 diabetes patients. Despite a greater use of health services by less wealthy patients, they showed worse glycaemic control and more chronic complications. Besides clinical variables, socio-economic status and environmental information need to be considered in the assessment of risk profile of diabetic patients by health professionals and by health service planners.

[Differential diagnosis among depressive pseudodementia, frontal dementia and subcortical dementia: a case report]. / Diagnóstico diferencial entre seudodemencia depresiva, demencia frontal y demencia subcortical: estudio de un caso.

Among the clinical entities that show cognitive impairments it may sometimes be difficult to reach a diagnosis. That is the case with the differential diagnosis among depressive pseudodementia, subcortical dementia without motor symptoms and predominantly frontal-mesial frontotemporal dementia. This current paper presents one clinical case that illustrates such difficulties. In the first place, clinical, neuropsychological and neuroimaging features as well as common features of these three disorders are described, after which the case, and evolution of the diagnostic process are described.
