Objective: To evaluate the differences between autochthonous and allochthonous women's participation in a breast cancer screening programme., Method: Retrospective study based on data from the Breast Cancer Screening Programme of the province of Tarragona (2008-2015). The sample is the target population of the programme with known country of origin., Results: Cohort of 40,824 women. Allochthonous women participate less than autochthonous women (41.8% vs. 72.3%) although they have a similar global detection rate to the latter but with differences according to the human development index of their country of origin. Both groups present similar tumour stages on detection (p=.59)., Conclusions: Strategies specifically aimed at the immigrant population are required to improve their participation in breast cancer screening., (Copyright © 2018 SESPAS.

The population movements during the last decades have resulted in a progressively increasing interest in certain infectious diseases. Eosinophilia is a common finding in immigrants and travellers. One of the most common causes of eosinophilia is helminth infection, and some intestinal protozoa. The aim of this paper is to describe the epidemiological characteristics of cases with eosinophilia and its association with the presence of parasites in the REDIVI data network. This is a multicentre prospective observational study that includes patients diagnosed with eosinophilia registered in the cooperative network for the study of infectious diseases in travellers and immigrants (+REDIVI) from January 2009 to December 2012. A total of 5,255 episodes were recorded in the network during the study period, and eosinophilia was observed in 8.1-31.3% of cases (depending on the immigration group). There were 60.2% men, with a median age of 31years. There were 72.4% immigrants, and 81.2% were asymptomatic. The most commonly identified parasites were S.stercoralis (34.4%), Schistosoma sp. (11.0%), and hookworm (8.6%). The relationship between eosinophilia and parasite infection was significant for all helminths (except for cutaneous larva migrans). The symptoms and duration of the journey did not significantly determine the presence of eosinophilia. In the case of eosinophilia in a person who has lived in helminth endemic areas, it is advisable to carry out targeted studies to diagnose the infection, regardless of immigration type, length of stay, or the presence of symptoms., (Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Objective: To determine the clinical, laboratory, serological and histologic characteristics of chronic hepatitis B virus carriers in our environment., Material and Methods: A retrospective cohort study was performed that included chronic AgHBs carriers aged more than 13 years attending our service since January 2000., Results: A total of 474 patients were included. At diagnosis, 55.49% were men, with a mean age of 41.05±13.93 years. Alanine aminotransferase (ALT) levels were within the normal range in 57.17% of the patients, and 87.76% were AgHBe(-). Hepatitis C and D virus coinfection was found in 3.62% and 1.86%, respectively. Liver biopsy was performed in 31.22%; varying grades of inflammation-fibrosis were found in 63.51% and cirrhosis was found in 12.84%. Compared with AgHBe(-) patients, those who were AgHBe(+) were younger and had greater disease activity. This difference was statistically significant. Patients in the immunotolerant phase were the least numerous (5.26%), while AgHBe(-) patients with chronic HBV infection were the most numerous (48.32%). Patients in the immunoreactive phase showed greater histological involvement (16.67% cirrhosis). A familial history of chronic HBV was found in 21.52%. The percentage of non-Spanish patients increased in the last few years and accounted for 18.78%., Conclusion: Chronic HBV infection in our environment occurs mainly in middle-aged persons. GPT values are normal in more than 50%, most are AgHBe(-), and approximately half are inactive carriers. The incidence of chronic infection has increased in the non-Spanish population in recent years., (Copyright © 2012 Elsevier España, S.L. and AEEH y AEG. All rights reserved.)

Objectives: To describe the variables associated with induced abortions in Andalusia (Spain) and the differences between native and foreign populations., Material and Methods: A cross-sectional population-based study was carried out. The files on deliveries and induced abortions were combined to create a single file for the period 2007-2010. A binary logistic regression model was employed. The dependent variable was whether the pregnancy ended in delivery or induced abortion. The independent variables were the year, province of residence, number of previous children, schooling, cohabitation and nationality. The raw and adjusted odds ratios and the 95% confidence intervals were calculated for native and foreign women., Results: Of 460,716 pregnancies, 17% ended in an induced abortion and 83% in delivery. The variables most closely associated with the risk of an induced abortion among native and foreign women in Andalusia were having three or more previous children (OR=23.06), being under 25 years old (OR=19.53), living alone (OR=10.04) and being an immigrant (OR=3.95), especially in African women. The rates of abortions, fecundity and fertility were higher in foreigners than in native women, with an increase in abortions and a decrease in fertility and fecundity., Conclusions: The women at greatest risk of having an abortion in Andalusia are young foreign women, especially those from Africa, who live alone, have previous children and secondary education and reside in the province of Huelva., (Copyright © 2011 SESPAS.

Objectives: To describe hospitalization rates and hospital morbidity among the foreign population residing in Aragon (Spain) by country of birth, between 2004 and 2007, and to compare these rates with those in the autochthonous population., Methods: A retrospective longitudinal study was carried out of hospital discharges of the foreign population in public hospitals in Aragon. Utilization rates were estimated by sex, age, country of birth and main diagnosis. Poisson regression was used to estimate the utilization rate ratios and their 95% confidence intervals., Results: Hospitalization rates were lower in the foreign population (adjusted RR: 0.52; 95% CI: 0.51-0.56), except in women aged between 15 and 24 years (RR: 2.9; 95% CI: 2.8-3.0) and among those born in the Maghreb (RR: 1.8; 95% CI: 1.7; 1.9), sub-Saharan Africa (RR: 2.0; 95% CI: 1.9-2.1) and Asia (RR=1.4; 95% CI: 1.3-1.6). When hospital discharges related to obstetrics and gynecology were excluded, only women born in sub-Saharan Africa continued to have adjusted RR greater than 1. These women had higher hospitalization rates in groups of infectious and parasitic diseases (RR: 2.5) and blood and blood-forming organs (RR: 2.8)., Conclusions: In Aragon (Spain), public hospital utilization is lower in foreigners than in the autochthonous population. The diseases treated varied by country of birth. The diseases prevalent in these countries, together with hereditary diseases, can increase hospital utilization rates., (Copyright © 2010 SESPAS.

Background: Molecular epidemiology is used in tuberculosis (TB) to identify clusters in which the cases are assumed to belong to the same recent transmission chain. An endogenous reactivation of latent TB is considered when the Mycobacterium tuberculosis isolates have a unique genotype., Objective: To describe factors associated with recent transmission of TB in Almeria, from 2003-2007., Methods: We conducted an observational prospective study that included patients with Mycobacterium tuberculosis positive culture. The strains were genotyped by Restriction Fragment Length Polymorphism and spoligotyping. Adjusted odds ratio and 95% confidence intervals were calculated to study factors associated with cluster groups, using a multivariate logistic regression model., Results: We analysed 427 isolates, of which 71% were from males and 56.2% of them belonged to foreign residents. Furthermore, 44% were classified as a cluster. The resistance to isoniazid was 8.4%. The factors associated with clusters were age, principally the group under 10 years (adjusted OR=12.75; 95% CI, 2.52-64.58) and the group aged between 50-59 years (adjusted OR=13.85; 95% CI, 3.04-63.17), and born in Spain (adjusted OR=2.17; 95% CI, 1.41-3.36)., Conclusions: In Almeria, native population, children under 10 years old and patients aged between 50-59 years have more probability to belong to the same recent transmission chain. The molecular epidemiology can be used to find out which population groups need more control and this information must be used in tuberculosis prevention programs., (Copyright © 2009 Elsevier España, S.L.

Objective: To study the prevalence and factors associated with HIV and HCV infection among inmates of a Spanish prison., Method: A cross-sectional study was carried out in July 2001. We determined HCV (ELISA and RIBA-3) and HIV (ELISA and Western-blot) serology in the prison population. Study variables included age, sex, nationality and previous intravenous drug use (IDU). In IDU inmates we analyzed the age when intravenous drug use was initiated, years of consumption, age at first admission in prison and syringe sharing with other inmates. The subpopulations of Arab and Romani (gypsy) inmates were studied differentially., Results: A total of 800 inmates (mean age 34.2 6 6.2 years) were evaluated; 74.3% were Spanish and 33.6% IDU. HCV serology was obtained in 730 inmates and HIV serology in 773 with the following seroprevalence results: HCV 38.2%, HIV 19.1% and HCV-HIV co-infection 18.8%. The variables associated with HCV or HIV infection in the univariate analysis were Spanish nationality, previous IDU and coinfection by the other virus. In the multivariate analysis, only coinfection and, particularly, previous IDU (HCV infection: adjusted ORp 104.8 [95% CI: 49.4-222.2]) (HIV infection adjusted ORp 45.1 [95% CI: 14.0-144.9]) maintained an association with the two infections., Conclusions: The prevalence of HIV and HCV infection and coinfection is high in Spanish prisons. Infection by either of these viruses and previous IDU were independently associated with both infections. The percentage of non-Spanish inmates with these infections is low.

Introduction: To determine the cost and volume of work implied in providing a parasitological diagnosis when attending immigrants in a referral Tropical Medicine Unit., Methods: The total number and type of samples, requests processed and parasitology laboratory costs were quantified after attending 1258 immigrants during the period January 1989 to December 2001. Estimation of laboratory workload for the total was made on the basis of results from 748 of these patients. A reference to relative value units (RVU) was established for each of the tests used in the parasitological diagnosis. The evaluation included costs related to disposable material and time spent by technicians and medical staff, but did not include costs related to sample extraction or processing of the test request. Modified indicators from the Catalogue of Microbiology studies of the Valencian Community for the year 2000 were used, establishing the equivalence of 1 RVU as the value of one urine culture 5 2.39 3 (398 pesetas)., Results: The overall cost was 99,680.99 3 (16,585,522 pesetas) or 45,934.94 RVU, and the cost per patient was 79.24 3 (13.185 pesetas) or 36.51 URV. The volume of work dedicated to attending immigrants was 9.7% of the total of samples received in the laboratory., Conclusions: The cost and volume of work involved in attending this group of patients in the parasitology laboratory was not high.
