The clinical interview of immigrant patients requires cultural competence to ensure good understanding and correct communication, in addition to collecting specific information that differs from that of native patients, such as origin and migratory route or cultural identity. Screening for latent tuberculosis infection is recommended in certain cases and screening for other infections, both cosmopolitan with a higher prevalence in migrants (HIV, syphilis, hepatitis B and C) and imported (Chagas, intestinal parasites, strongyloidiasis, schistosomiasis), depending on origin. It is essential to check the vaccination status and complete the vaccination schedule, adapting it to the current calendar, prioritizing vaccines such as measles, rubella and poliomyelitis. We propose preventive activities to be carried out when traveling to countries of origin, due to their special characteristics and risks: general advice, exploring the risk of malaria, assessing specific vaccinations, advice regarding sexually transmitted infections and special considerations if they have chronic diseases; and addressing, if appropriate, the risks of female genital mutilation., (Copyright © 2024 The Authors.

Background: In the past few years, the Canary Islands received immigrants from sub-Saharan countries that arrive to the coast after long boat trips in extreme adverse conditions. The named «trench foot» is a previously described infectious entity developed after feet wounds that get infected by being in contact with water, urine and excrements in these small and crowded boats. We describe a new clinical entity, not published yet, that consists in massive edema in the extremities associating necrosis of the skin and subcutaneous tissue that characteristically respects the muscle and with a non-infectious etiology., Material and Methods: A database including 86 patients arrived by boat («patera») from sub-Saharan countries from September 2020 to January 2022 was made and 39 qualitative and quantitative items were analyzed. The Research Unit performed an observational prospective statistical analysis., Results: A total of 16 patients developed the entity described as necrotizing cellulitis. Its physiopathology completely differs from the one described in the trench foot, since all the cultures resulted sterile., Conclusions: We postulate an inflammatory theory due to the osmotic effect from ingesting sea water and/or the aggressive fluid reposition when they arrive to the emergency room with severe dehydration and hypernatremia. Early surgical evacuation of the edema with escharotomies incisions alleviate the symptoms and prevents progression of the disorder., (Copyright © 2023 Elsevier España, S.L.U. All rights reserved.)

Objective: To characterize the diet and eating habits of adult immigrants of Chinese origin residing in Santa Coloma de Gramenet (Barcelona, Spain), and to identify the factors that influence the changes in diet and eating habits., Method: Qualitative study conducted in 2017 through a discussion group with eight adults of Chinese origin (one man and seven women). The information was complemented by five interviews with key informants (three men and two women) and non-participant observation in health promotion workshops aimed at Chinese patients of a health center in Santa Coloma de Gramenet., Results: Chinese adults made three meals a day and tended to snack between meals. Their diet was based on rice, soy and proteins of vegetable origin. Participants rarely consumed milk and milk derivatives but highlighted their consumption of snacks, sugary drinks and pastries, as well as the incorporation of foods, new dishes and cooking techniques from the host country. The Chinese immigrants tried to maintain their diet of origin, however there were various barriers to this, such as the preference of the local diet by the children, work schedules and lack of time., Conclusions: A tendency towards dietary acculturation is observed among the participants. Health promotion activities aimed at Chinese families are needed to improve aspects of their diet and eating habits, aiming to reduce the consumption of snacks and sugary products., (Copyright © 2019 SESPAS.

Objective: Gender-based violence against women migrant domestic workers (WMDW) is a serious public health concern in the Middle East region. The current study is the first to explore abuse of WMDW as perceived by recruitment agency managers., Method: A qualitative study was conducted using 42 personal semi-structural interviews with agency managers in Lebanon. The interview guidelines were designed based on the standards set by the International Labor Organization (ILO) Convention No. 189. The information was transcribed in Arabic, and data was analyzed using thematic analysis., Results: The interviewees believe that WMDW are subject to abusive practices that represent various violations of the ILO Convention No. 189, including harassment and violence, compulsory labour, misinformation about conditions of employment, denial of periods of rest and restriction of movement and travel documents. In many situations, the interviewees justified some of these practices as being necessary to protect their business and to protect the workers., Conclusion: The results of this study have several policy implications for the protection of WMDW against abuse., (Copyright © 2018 SESPAS.

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.

Introduction: Onchocerciasis is caused by Onchocerca volvulus and mainly leads to pruritus and skin and visual disorders, including blindness. Seventeen million people are infected in 38 countries; 31 of these are in sub-Saharan Africa, six in Latin America and one on the Arabian Peninsula. More than 99% of cases occur in sub-Saharan Africa where 120 million people are at risk of infection. Eye disorders have been well-documented; however, skin disorders have not been described accurately. The objective of our study was to describe the epidemiology, main skin manifestations and treatment of imported onchocerciasis., Material and Methods: A retrospective study was thus conducted by analysing the main demographic, clinical and treatment data regarding a cohort of 400 patients attending a reference clinical unit over a 17-year period., Results: Most patients were female (55%) with mean age 37.5±16.7 years. All the migrants came from sub-Saharan countries. The most frequently occurring dermatological symptom was pruritus. Ivermectin had been used as first-line therapy and adverse reactions had been described in 11 patients (3.2%)., Conclusions: The results indicate the fact that there should be a clinical suspicion of onchocerciasis regarding immigrants from endemic areas having skin lesions compatible with the disease's profile or asymptomatic patients having eosinophilia or unexplained high IgE. Moreover, skin snips from the buttocks region were very fruitful and treatment with ivermectin was seen to be safe. This is the largest case series regarding imported onchocerciasis described up to the present time., (Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Introduction: Some studies indicate high prevalences of latent tuberculosis infection (LTBI) in the immigrant population, which is relevant because 5-10% of cases will develop active tuberculosis. The objective of this study is to describe the results of a sequential strategy in the newly-arrived immigrant population for the diagnosis of LTBI using the tuberculin skin test (TST) and IGRAs., Methods: A retrospective descriptive study was carried out with immigrants between 6 and 35years of age from shelters, referred to an international health unit between July 2013 and June 2016. The TST was performed and when it was ≥5mm, IGRAs were conducted. LTBI was defined as an IGRA ≥0.35IU/ml and normal chest X-ray., Results: Of the 184 cases, 138 (75.0%) were men, 23.0 years of age. The most common geographical areas were: 63 (34.2%) from Asia, 42 (22.8%) from Eastern Europe and 41 (22.3%) from sub-Saharan Africa. The TST was ≥10mm in 79 cases (42.9%). The prevalence of LTBI using the sequential strategy was 33/184 (17.9%). Cohen's Kappa index (between TST≥10mm and IGRAs) was 0.226., Conclusion: Basing LTBI screening on the TST alone could give rise to an overestimation. Some studies show that sequential screening would be the most cost-effective; this seems most evident in BCG-vaccinated populations., (Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Objective: To analyse changes in health professionals' and immigrant users' perceptions of the quality of care provided to the immigrant population during the crisis., Methods: A qualitative descriptive-interpretative and exploratory study was conducted in two areas of Catalonia. Semi-structured individual interviews were used with a theoretical sample of medical (n=24) and administrative (n=10) professionals in primary care (PC) and secondary care (SC), and immigrant users (n=20). Thematic analysis was conducted and the results were triangulated., Results: Problems related to technical and interpersonal quality emerged from the discourse of both professionals and immigrants. These problems were attributed to cutbacks during the economic crisis. Regarding technical quality, respondents reported an increase in erroneous or non-specific diagnoses, inappropriate use of diagnostic tests and non-specific treatments, due to reduction in consultation times as a result of cuts in human resources. With regard to interpersonal quality, professionals reported less empathy, and users also reported worse communication, due to changes in professionals' working conditions and users' attitudes. Finally, a reduction in the resolution capacity of the health services emerged: professionals described unnecessary repeated PC visits and limited responses in SC, while young immigrants reported an insufficient response to their health problems., Conclusion: The results indicate a deterioration in perceived technical and interpersonal quality during the economic crisis, due to cutbacks mainly in human resources. These changes affect the whole population, but especially immigrants., (Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.)

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 examine the effect of perceived discrimination and self-rated health among the immigrant population in the Basque Country, Spain, and determine whether this effect varies according to region of origin, age, sex and education., Methods: Descriptive cross-sectional study. The study population included immigrants aged 18 and older residing in the Basque Country. Data from the 2014 Foreign Immigrant Population Survey (n=3,456) were used. Log-binomial regression was used to quantify the association between perceived discrimination and self-rated health before and after checking for the selected characteristics., Results: Almost 1 in 10 immigrant adults reports perceiving discrimination. In adjusted analyses, the immigrants perceiving discrimination were almost were 1.92 more likely to rate their health as poor (prevalence ratio: 1.92; 95% CI: 1.44-2.56) than those who did not report discrimination. This association did not vary according to region of origin, age, sex or educational level., Conclusions: Perceived discrimination shows a consistent relationship with perceived health. Moreover, this association did not depend on the region of origin, age, sex or educational level of immigrants. These results show the need for implementing inclusive policies to eliminate individual and institutional discrimination and reduce health inequalities between the immigrant and native populations., (Copyright © 2017.

Introduction: In Spain, minors represent approximately 20% of the immigration flow. Many of these immigrants come from countries in the tropics and sub-tropics where intestinal parasitic infections caused by helminths and protozoa are one of the major causes of human disease. The main objective of the present work was to describe parasite infections in a group of immigrant children., Methods: A prospective evaluation was performed in 373 minors from Sub-Saharan Africa, North Africa, and Latin America. Details were collected from the medical records and physical examination. Urine, stool and peripheral blood samples were obtained for serological and routine laboratory tests. Direct and indirect parasitological tests were also performed., Results: At least 1 parasitic disease was diagnosed in 176 (47.1%) immigrant children, while 77 (20.6%) minors were infected with two or more parasites. The number of parasites was highest in children from Sub-Saharan Africa compared with the rest of the areas of origin (p<.001), and in children from urban areas compared with those from rural areas (OR 1.27 [1.059-1.552], p=.011). The most frequent causes of multiple parasite infection were filariasis plus strongyloidiasis and filariasis plus schistosomiasis. Intestinal parasite infection was diagnosed in 38 cases (13.8%). Logistic regression analysis revealed that for each month of stay, the probability of a positive finding in the stool sample decreased by 0.02% [β=-0.020, (p=.07)]., Conclusions: The high infection rates of parasite diseases in immigrant children point to the need for screening protocols for certain infectious diseases in these children according to their country of origin and their length of residence in Spain., (Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Eosinophilia is a common finding in international travelers and immigrants, being an helmintic infection its main etiology. The positive predictive value of eosinophilia for an helmintosis is low in travellers. Eosinophilia may be an incidental finding, or symptomatic, and it represents a clinical challenge due to the low sensitivity and specificity of direct and indirect parasitological diagnostic tests, respectively. It requires a structured approach based on geographical areas, environmental exposures and behavioral risks, and associated symptoms. The initial assessment should include a comprehensive and tailored anamnesis and physical examination, basic laboratory tests, a complete parasitological examination of stool samples and a Strongyloides stercoralis serology, supplemented with other explorations guided by epidemiological and clinical suspicion. Empiric treatment with albendazole and/or ivermectin (plus praziquantel if risk of schistosomiasis) is an option for unidentified persistent eosinophilia after study, and in persons in whom a proper assessment or follow-up can not be assured. In patients at risk for estrongiloidosis who are candidates for immunosuppressive therapies, it is indicated a prior screening and treatment to prevent a future hyperinfestation syndrome., (Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Objective: 1) to examine the discourses of professionals involved in the care of female victims of intimate partner violence (IPV), with emphasis on how they describe the immigrant women, the perpetrators and their own responsibility of care; and 2) to compare these discourses with the other professions involved in caring for these women (social services, associations and police and justice)., Methods: Qualitative study based on semi-structured interviews with 43 professionals from social services, associations and the police and judicial systems. A discourse analysis was carried out to identify interpretive repertoires about IPV, immigrant women and their aggressors, their culture and professional practices., Results: Four interpretive repertoires emerged from professional discourses: "Cultural prototypes of women affected by IPV", "Perpetrators are similar regardless of their culture of origin", "Are victims credible and the perpetrators responsible?" and "Lack of cultural sensitivity of professionals in helping immigrant women in abusive situations". These repertoires correspond to preconceptions that professionals construct about affected women and their perpetrators, the credibility and responsibility they attribute to them and the interpretation of their professional roles., Conclusions: The employment of IPV-trained cultural mediators in the services responsible for caring for the female victims, together with cultural training for the professionals, will facilitate the provision of culturally sensitive care to immigrant female victims of intimate partner violence., (Copyright © 2016 SESPAS.

Parasitic diseases suppose an important health problem in people from high endemic areas, so these must be discarded properly. Usually, these infections develop asymptomatically but, in propitious situations, are likely to reactivate themselves and can cause clinical symptoms and/or complications in the receiving country. Moreover, in some cases it is possible local transmission. Early diagnosis of these parasitic diseases made by appropriate parasitological techniques and its specific treatment will benefit both, the individual and the community. These techniques must be selected according to geoepidemiological criteria, patient's origin, migration route or time spent outside the endemic area; but other factors must also be considered as its sensitivity and specificity, implementation experience and availability. Given the high prevalence of intestinal parasites on asymptomatic immigrants, it is recommended to conduct a study by coproparasitological techniques. Because of its potential severity, the screening of asymptomatic malaria with sensitive techniques such as PCR (polymerase chain reaction) is also advisable. Serological screening for Chagas disease should be performed on all Latin American immigrants, except for people from the Caribbean islands. Other important parasites, which should be excluded, are filariasis and urinary schistosomiasis, by using microscopic examination. The aim of this paper is to review the different techniques for the screening of parasitic diseases and its advices within the care protocols for asymptomatic immigrants., (Copyright © 2016 Elsevier España, S.L.U.

Background: Viral hepatitis is a significant health problem in African countries. The increase in the immigrant population from this continent represents a challenge for the Spanish healthcare system., Material and Methods: A descriptive study was conducted on the prevalence of the serological markers of hepatitis B (HBV), C (HCV) and D (HDV) in African immigrants treated in a specialised doctor's office., Results: The study included 2518 patients (87.7% Sub-Saharan natives), with a mean age of 31.3 years. Some 78.8% of the patients had a positive infection marker for HBV, and 638 patients (25.3%) were diagnosed with active hepatitis B (HBsAg +). In 19 cases, antibodies against HDV were detected (4 cases with detection of the viral genome). Sixty-eight patients had antibodies against HCV, 26 of whom had a positive viral load., Conclusions: The high prevalence of viral hepatitis in immigrants, especially HBV infection, represents a significant change in the profile of patients treated in Spain and requires measures aimed at early diagnosis and transmission prevention., (Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI).

The incidence of tuberculosis worldwide is declining. However, in Western countries this decline is slower due to the impact of immigration. Tuberculosis in the immigrant population is related to health status in the country of origin and with overcrowding and poverty conditions in the host country. Immigrants with tuberculosis are younger, have a higher prevalence of extrapulmonary forms, greater proportion of drug resistance and higher treatment default rates than those of natives. New molecular techniques not only reduce diagnostic delay time but also allow the rapid identification of resistances and improve knowledge of transmission patterns. It is necessary to implement measures to improve treatment compliance in this population group like facilitating access to health card, the use of fixed-dose combination drugs, the participation of cultural mediators and community health workers and gratuity of drugs., (Copyright © 2016 Elsevier España, S.L.U. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Introduction: To determine the infectious diseases (ID) that led to hospital admission of the foreign population>14 years., Material and Methods: A retrospective study of foreign patients admitted to hospital (2000-2012)., Results: A total of 3,087 foreigners were admitted with infectious diseases. Of these, 73.6% were from low income countries, and 26.4% from high income countries. Most of them (86.9%) were admitted with common ID, 11.8% with transmissible ID, and 1.6% with tropical ID. Tropical ID and transmissible ID were higher in patients from low income countries (14.7%) than from high income countries (9.7%, p<0.001). The main tropical ID was malaria (74%). The main transmissible ID were tuberculosis (40.3%), hepatitis (27.8%), and HIV/AIDS (27.5%)., Conclusion: Common ID were the main reason for admission in foreign population., (Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Background and Objective: The aim of this study was to determine the prevalence of tuberculosis infection in undocumented immigrant teenagers using a tuberculin skin test (TST) for initial screening and QuantiFERON(®)-TB Gold In-Tube (QFT-GIT) as a confirmatory test., Patient and Method: From 2007 to 2012, under 19 year-old immigrant teenagers from 2 accommodation centers of the Basque Country (Spain) were included in the study. The TST was done in all of them and the QFT-GIT was done in selected patients with a TST≥5mm., Results: Eight hundred and forty-five immigrants were included, most of them from Africa (99.5%). Fifty-one percent of immigrants with TST ≥ 5 mm has a positive QFT-GIT. We found 2 cases of active tuberculosis (2/845: 0.24%). The concordance between TST (≥ 10 mm) and QFT-GIT was 63%, with 57% of positive concordance cases and 96% of negative concordances. There were 246 cases with TST ≥ 10 mm (29%), with significant differences between Magrebis (21.5%) and Subsaharians (67%) (P<.001). Vaccination with Calmette-Guéin bacille was an independent predictor for having a TST ≥ 10 mm (OR: 2.11; P<.001) and for the discordance TST+/QFT-GIT-, both for a TST≥5 and a TST≥10mm (OR 2.16, 95% confidence interval [95% CI] 1.46-3.20, and OR 1.91 95% CI 1.23-2.97, respectively). The positive value of QFT-GIT increased significantly as the TST increased, with a positive association in all the cut-off points analyzed: 10-14 mm (OR 7.95, 95% CI 1.79-35.33), 15-19 mm (OR 35, 95% CI 7.93-154.52) and ≥ 20 mm (OR 91.3, 95% CI 18.20-458.11)., Conclusion: Due to the high prevalence of latent tuberculosis infection in Subsaharian immigrants, we recommend implementing screening programs in this population. Using QFT-GIT, the number of candidates for chemoprophylaxis was reduced to 43% compared with TST alone (≥ 10 mm)., (Copyright © 2013 Elsevier España, S.L.U. All rights reserved.)

Objective: To establish the prevalence of Trypanosoma cruzi infection in Bolivian (Spain) participants., Methods: A cross sectional study was carried out in Majorca. Bolivian residents older than 18 years assigned to the family physicians of two primary care centers were randomly selected from the health card population database. Participants were invited to attend a serology test and an interview. T. cruzi infection was confirmed after two positive ELISA tests. If the result was positive or dubious, the serological test was sent to the National Microbiology Center for confirmation., Results: A total of 251 participants were included (response rate 36.3%). The overall seroprevalence of Chagas infection was 19.1% (95% CI: 14.06-24.19). Seroprevalence was higher in participants from highly endemic provinces, those from rural areas, those who had lived in mud houses, and in those whose mother or a family member had contracted this infection., Conclusion: This study demonstrates a high prevalence of T. cruzi in Bolivian residents, which was strongly associated with established risk factors., (Copyright © 2014 SESPAS.

A study was performed to assess differences in the clinical presentation of tuberculosis between two groups of immigrants. Ninety-four patients seen in the emergency room for newly diagnosed tuberculosis between 2006 and 2012 were included. Forty-nine patients were from Asian countries and 45 from Latin America. Mean age [years (SD)] was 35.3 (13) in Asian patients and 33.9 (10) in Latin American patients. Asian subjects were predominantly male (40/49 vs 25/45; P=0.006). Patients from Latin American countries had a higher rate of pulmonary tuberculosis. A higher percentage of Asian patients lived in overcrowded conditions, whereas HIV infection was more frequent among Latin Americans. Most patients were treated with a quadruple regimen. Resistance to isoniazid was documented in two patients from Latin America., (Copyright © 2014 SEPAR. Published by Elsevier Espana. All rights reserved.)

Objective: To describe perceived quality of life in Latin American caregivers working in Spain and how it varies in relation to certain variables shared by this group., Methods: We used the SF-36 to measure perceived quality of life in 517 women residing in five Spanish regions: the Balearic Islands, Catalonia, the Basque Country, the Canary Islands, and Madrid. Several variables related to the socio-demographic profile and migration process were studied using Student's t test, ANOVA and linear regression models., Results: The participants scored very low on the dimensions of physical and emotional roles. The factors associated with lower quality of life scores within the group were working as a live-in caregiver, lack of contract, multitasking, irregular status, and younger age., Conclusions: The vulnerability of these women can be explained by poor working conditions and other factors related to the migratory process., (Copyright © 2014 SESPAS.

Objective: To analyse clinical and epidemiological characteristics of immigrant patients diagnosed with strongyloidiasis in our area., Methods: An analyse was performed on patients with strongyloidiasis seen in the Tropical Medicine Unit of the "Hospital de Poniente" in Almeria (Spain), from April 2004 to May 2012., Results: A total of 320 patients were diagnosed with Strongyloides stercoralis infection, and 284 out of 314 patients (90.4%) had a positive specific serology. Forty-two percent of the patients reported symptoms and 45% had eosinophilia. The serological results were monitored in some of the patients, confirming a loss of antibodies in all 20 patients studied., Conclusions: Strongyloidiasis is a parasitic disease increasingly diagnosed in developed countries due to increased migratory flows from endemic areas. Often being asymptomatic, its diagnosis and treatment may prevent fatal outcomes, especially in immunocompromised patients., (Copyright © 2013 Elsevier España, S.L.U. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Objective: To compare the morbidity burden of immigrants and natives residing in Aragón, Spain, based on patient registries in primary care, which represents individuals' first contact with the health system., Methods: A retrospective observational study was carried out, based on linking electronic primary care medical records to patients' health insurance cards. The study population consisted of the entire population assigned to general practices in Aragón, Spain (1,251,540 individuals, of whom 12% were immigrants). We studied the morbidity profiles of both the immigrant and native populations using the Adjusted Clinical Group System. Logistic regressions were conducted to compare the morbidity burden of immigrants and natives after adjustment for age and gender., Results: Our study confirmed the "healthy immigrant effect", particularly for immigrant men. Relative to the native population, the prevalence rates of the most frequent diseases were lower among immigrants. The percentage of the population showing a moderate to very high morbidity burden was higher among natives (52%) than among Latin Americans (33%), Africans (29%), western Europeans (27%), eastern Europeans and North Americans (26%) and/or Asians (20%). Differences were smaller for immigrants who had lived in the country for 5 years or longer., Conclusion: Length of stay in the host country had a decisive influence on the morbidity burden represented by immigrants, although the health status of both men and women worsened with longer stay in the host country., (Copyright © 2014 SESPAS.

Introduction: An Imported Diseases Clinic was created in the hospital in 2009. The aim of this study was to asses its contribution in terms of capacity, quality of care and teaching offered., Patients and Methods: A retrospective study was conducted from 2009 to 2011, analyzing: A) development of knowledge by means of protocols and publications created, and subject taught; B) capacity and quality of care offered by the analysis of patients seen, the adequacy of the protocols and accessibility. The patients were classified into 3 groups. Group 1: immigrant patient screening, group 2: patient consultation after tropical or sub-tropical travel, group 3: screening of vertical transmission of imported disease., Results: Six protocols have been developed and disseminated on the unit website, as well as 5 scientific publications. A total of 316 patients were evaluated: 191 included in group 1 (29 Adopted and 162 Immigrants), 57 in group 2 (94.7% Visiting Friends and Relatives and 81.5% without a pre-travel consultation). They consulted due to, gastrointestinal symptoms (52.6%) and fever (43.8%), with 68 included in group 3 at risk of imported disease by vertical transmission (62 Trypanosoma cruzi, 1 Human T Lymphotropic Virus and 5 Plasmodium spp.). The overall adherence to the protocols was about 77.1%., Discussion: Infectious Diseases Units must adapt to the reality of the population and be flexible in its structure. Periodic assessment of the quality of care offered is essential, as well as an evaluation on the need for additional studies., (Copyright © 2013 Asociación Española de Pediatría.

Objective: Immigrants who make or plan journeys to visit their families in their countries of origin (immigrants -visiting friends and relatives, I-VFR) have a higher risk of acquiring travel-associated diseases than other travellers. The main aim of this study is to analyse the knowledge of the immigrant population on the need to receive health advice (HA) before making international journeys in general and in particular before travelling to their country of origin., Design: Observational, multicentre study., Setting: Ten Family Doctors from 10 Health Centres in Catalonia and Aragon participated, Participants: A total of 555 immigrants ≥ 15 years of age, who consulted their Family Doctor and agreed to answer a questionnaire. Opportunity sampling was used., Results: A total of 389 (70.1%) of those surveyed considered it necessary to receive HA before making an international journey, 406 (73.2%) were I-VFR and 145 (35.7%) had requested HA prior to the journey, mostly from their Family Doctor (n=60; 41.1%). Almost two-thirds (261, 65.2%) of the subjects did not seek HA, with the most common reason being that they did not consider it necessary (173, 42.6%)., Conclusions: I-VFR do not usually request HA prior to travelling, basic due to considering it unnecessary. When they do request it, they are very often initially directed to their Family Doctor., (Copyright © 2013 Elsevier España, S.L. All rights reserved.)

Introduction: Immigrant mothers in Spain have a lower risk of delivering Low BirthWeight (LBW) babies in comparison to Spaniards (LBW paradox). This study aimed at revisiting this finding by applying a model-based threshold as an alternative to the conventional definition of LBW., Methods: Vital information data from Madrid was used (2005-2006). LBW was defined in two ways (less than 2500g and Wilcox's proposal). Logistic and linear regression models were run., Results: According to common definition of LBW (less than 2500g) there is evidence to support the LBW paradox in Spain. Nevertheless, when an alternative model-based definition of LBW is used, the paradox is only clearly present in mothers from the rest of Southern America, suggesting a possible methodological bias effect., Conclusion: In the future, any examination of the existence of the LBW paradox should incorporate model-based definitions of LBW in order to avoid methodological bias., (Copyright © 2013 SESPAS.

Objectives: To study the clinical and epidemiological characteristics of immigrant patients diagnosed with a hookworm infection in the Tropical Medicine Unit of the Hospital de Poniente in El Ejido (Almería, Spain)., Material and Methods: A retrospective observational study of all immigrant patients diagnosed with hookworm, by direct visualization of eggs in stool samples, from October 2004 until December 2012., Results: Of the 1872patients studied, 253 (13.5%) were diagnosed with a hookworm infection. In patients where hookworm was the only helminthiasis diagnosed, 8.3% had iron deficiency anaemia, 65.7% did not have eosinophilia, and of these, 25.9% had no abdominal pain., Conclusions: Hookworm is a frequent parasite infestation in the Sub-Saharan immigrant population. Many patients are asymptomatic; thus the implementation of a study protocol for immigrants from endemic areas could diagnose and treat more patients with this disease., (Copyright © 2013 Elsevier España, S.L.

Introduction: There is a perception that the number of pediatric travelers is increasing, mainly due to the so-called visiting friends and relatives (VFRs) group. Both the demographic and trips characteristics in this group may lead to an increased risk and a greater complexity in vaccinations and other preventive recommendations., Objective: To analyze the outcomes of different groups of pediatric travelers. To describe the demographic and travel characteristics within the pediatric population, and to analyze whether the VFRs differ from non-VFRs with regards to the factors that may contribute to a greater risk., Methodology: A cross sectional descriptive study of the characteristics of pediatric travelers treated in the International Pre-travel Consultation Unit of the University Hospital Vall d'Hebron, from July 2002 to January 2009., Results: Of the 692 children analyzed, with a mean age of 8 years (SD 5.4), an increase in the overall number of travelers was identified, along with an initial increase in the number of VFR children in the early years of the study, although later on, the numbers of this group stabilized. The mean age of the VFR travelers was also found to be lower. A lack of planning prior to the start of the travel was also noted in the VFRs group, as well as longer trip durations. A routine vaccine was administered to 29.2% of children, and malaria prophylaxis was recommended for 52% of travelers., Conclusion: Despite the progressive increase in international travel and the initial increase in VFR travelers, the percentage of this group has remained stable in recent years. However, the perception of a low risk among the immigrant population suggests the need to encourage an adequate pre-travel consultation within this group., (Copyright © 2012 Asociación Española de Pediatría.
