Comparison of the consumption of antidepressants in the immigrant and native populations in a Spanish health region: an observational study

BackgroundHealth professionals and organizations in developed countries adapt slowly to the increase of ethnically diverse populations attending health care centres. Several studies report that attention to immigrant mental health comes up with barriers in access, diagnosis and therapeutics, threatening equity. This study analyzes differences in exposure to antidepressant drugs between the immigrant and the native population of a Spanish health region.MethodsCross-sectional study of the dispensation of antidepressant drugs to the population aged 15 years or older attending the public primary health centres of a health region, 232,717 autochthonous and 33,361 immigrants, during 2008. Data were obtained from computerized medical records and pharmaceutical records of medications dispensed in pharmacies. Age, sex, country of origin, visits, date of entry in the regional health system, generic drugs and active ingredients were considered. Statistical analysis expressed the percentage of persons exposed to antidepressants stratified by age, gender, and country of origin and prevalence ratios of antidepressant exposition were calculated.ResultsAntidepressants were dispensed to 11% of native population and 2.6% of immigrants. Depending on age, native women were prescribed antidepressants between 1.9 and 2.7 times more than immigrant women, and native men 2.5 and 3.1 times more than their immigrant counterparts. Among immigrant females, the highest rate was found in the Latin Americans (6.6%) and the lowest in the sub-Saharans (1.4%). Among males, the highest use was also found in the Latin Americans (1.6%) and the lowest in the sub-Saharans (0.7%). The percentage of immigrants prescribed antidepressants increased significantly in relation to the number of years registered with the local health system. Significant differences were found for the new antidepressants, prescribed 8% more in the native population than in immigrants, both in men and in women.ConclusionsAll the immigrants, regardless of the country of origin, had lower antidepressant consumption than the native population of the same age and sex. Latin American women presented the highest levels of consumption, and the sub-Saharan men the lowest. The prescription profiles also differed, since immigrants consumed more generics and fewer recently commercialized active ingredients.

Ischemic heart disease and primary care: identifying gender-related differences. An observational study

BackgroundGender-related differences are seen in multiple aspects of both health and illness. Ischemic heart disease (IHD) is a pathology in which diagnostic, treatment and prognostic differences are seen between sexes, especially in the acute phase and in the hospital setting. The objective of the present study is to analyze whether there are differences between men and women when examining associated cardiovascular risk factors and secondary pharmacological prevention in the primary care setting.MethodsRetrospective descriptive observational study from January to December of 2006, including 1907 patients diagnosed with ischemic heart disease in the city of Lleida, Spain. The clinical data were obtained from computerized medical records and pharmaceutical records of medications dispensed in pharmacies with official prescriptions. Data was analyzed using bivariate descriptive statistical analysis as well as logistic regression.ResultsThere were no gender-related differences in screening percentages for arterial hypertension, diabetes, obesity, dyslipemia, and smoking. A greater percentage of women were hypertensive, obese and diabetic compared to men. However, men showed a tendency to achieve control targets more easily than women, with no statistically significant differences. In both sexes cardiovascular risk factors control was inadequate, between 10 and 50%. For secondary pharmaceutical prevention, the percentages of prescriptions were greater in men for anticoagulants, beta-blockers, lipid-lowering agents and angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, with age group variations up to 10%. When adjusting by age and specific diagnoses, differences were maintained for anticoagulants and lipid-lowering agents.ConclusionScreening of cardiovascular risk factors was similar in men and women with IHD. Although a greater percentage of women were hypertensive, diabetic or obese, their management of risk factors tended to be worse than men. Overall, a poor control of cardiovascular risk factors was noted.Taken as a whole, more men were prescribed secondary prevention drugs, with differences varying by age group and IHD diagnosis.

Prognostic role of stress echocardiography in hypertrophic cardiomyopathy: The International Stress Echo Registry.

BACKGROUND Stress echo (SE) may have a role in the outcome in patients with hypertrophic cardiomyopathy (HCM). OBJECTIVES The aim was to assess the prognostic value of SE in a retrospective multicenter study in HCM. METHODS We enrolled 706 HCM patients. The employed stress was exercise (n=608) and/or vasodilator (n=146, dipyridamole in 98 and adenosine in 48). We defined SE positivity according to clinical/hemodynamic criteria including: symptoms (all stress modalities), exercise-induced hypotension (failure to increase or fall >20mmHg, exercise) and exercise-induced left ventricular outflow tract obstruction (left ventricular outflow tract obstruction >50mmHg); and ischemic criteria, such as new wall motion abnormalities (new wall motion abnormality) and/or reduction of coronary flow reserve velocity (CFVR≤2.0) on left anterior descending coronary artery with vasodilator stress assessed in 116 patients. All patients completed the clinical follow-up. RESULTS Positive SE showed more frequently CFVR reduction, exercise-induced hypotension, left ventricular outflow tract obstruction, and symptoms (38, 23, 20 and 15% respectively), but new wall motion abnormality only in 6%. During a median follow-up of 49months 180 events were observed, including 40 deaths. Clinical/hemodynamic criteria did not predict outcome (X2 0.599, p=0.598), whereas ischemia-related SE criteria (X2: 111.120, p<0.0001) was significantly related to outcome. Similarly, mortality was predicted with SE ischemic-criteria (X2 16.645, p<0.0001). CONCLUSIONS SE has an important prognostic significance in HCM patients, with ischemia-related end-points showing greater predictive accuracy than hemodynamic endpoints. New wall motion abnormalities and impairment of CFVR should be specifically included in SE protocols for HCM.

Efficacy and tolerance of the topical application of potassium hydroxide (10% and 15%) in the treatment of molluscum contagiosum: Randomized clinical trial: Research protocol

BackgroundMolluscum contagiosum is a non-severe pediatric viral infection. Because it is highly contagious and current treatments have negative aesthetic and psychological effects, we want to test an alternative treatment in the primary care setting, consisting of two different concentrations of potassium hydroxide solution.Methods/designThe study design is a double-blind, randomized clinical trial, using three types of topical treatment. The treatment consist of daily applications of potassium hydroxide (KOH) in aqueous solution at 10% and 15% concentration, and a placebo administered in the control group. Four follow-up visits (at 15, 30, 45 and 60 days) are planned to evaluate treatment effectiveness and patient tolerance.The main outcome measure of the trial will be the healing rate, defined as lesion disappearance in the affected zones after the topic application of the experimental treatment. Secondary measures will be the principal characteristics and evolution of the affected zone (surface area, number of lesions, size and density of lesions), treatment tolerance (hyperpigmentation, itching, burning, pain), recurrence rate and the natural evolution of lesions in the control group.DiscussionKOH can potentially be an effective and safe treatment for MC in primary care, and can also reduce referrals to dermatologists and hospital pediatric departments. In addition, KOH may be a valid and less expensive alternative to current invasive treatments (surgical excision).Trial RegistrationClinicalTrials.gov: NCT01348386

La población inmigrante controla peor su diabetes que la población autóctona

INTRODUCTION Ethnic differences are known to exist in the prevalence of diabetes, but little is known about possible differences in the degree of diabetes control among ethnic groups. The aim of this study was to determine whether there are differences in diabetes detection and control between immigrants and the autochthonous population in our health region. METHODS We performed a cross-sectional, observational, population-based study of all patients diagnosed with diabetes mellitus type 2 registered and treated in 2010. We analyzed diabetes quality indicators and used multivariate logistic regression models adjusted for age, sex and number of visits. The adjustment method was forced and the absence of collinearity was identified through the ROC curve and Hosmer and Lemeshows test. RESULTS There were 77,999 autochthonous patients (6,846 diabetics) and 30,748 immigrant patients (415 diabetics). A total of 8.78% of the autochthonous patients were diabetic versus 1.35% of immigrants (p <0.001). HbA1c <7.5% was found in 68.04% of the native population compared with 54.76% of immigrants. The probability of achieving optimal HbA1c control was 27% lower in immigrants (adjusted OR=0.73), while the probability of achieving good HbA1c control was 30% lower in the immigrant cohort. The model showed moderate discrimination (ROC =0.65 and Hosmer and Lemeshows contrast, p>0.05). CONCLUSIONS Diabetes control and quality indicators are poorer in some immigrant groups.

Duration and compliance with antidepressant treatment in immigrant and native-born populations in Spain: a four year follow-up descriptive study

BackgroundNon-compliance with antidepressant treatment continues to be a complex problem in mental health care. In immigrant populations non-compliance is one of several barriers to adequate management of mental illness; some data suggest greater difficulties in adhering to pharmacological treatment in these groups and an increased risk of therapeutic failure.The aim of this study is to assess differences in the duration and compliance with antidepressant treatment among immigrants and natives in a Spanish health region.MethodsPopulation-based (n=206,603), retrospective cohort study including all subjects prescribed ADT between 2007 and 2009 and recorded in the national pharmacy claims database. Compliance was considered adequate when the duration was longer than 4months and when patients withdrew more than 80% of the packs required.Results5334 subjects (8.5% of them being immigrants) initiated ADT. Half of the immigrants abandoned treatment during the second month (median for natives=3months). Of the immigrants who continued, only 29.5% presented good compliance (compared with 38.8% in natives). The estimated risk of abandoning/ending treatment in the immigrant group compared with the native group, adjusted for age and sex, was 1.28 (95%CI 1.16-1.42).ConclusionsIn the region under study, immigrants of all origins present higher percentages of early discontinuation of ADT and lower median treatment durations than the native population. Although this is a complex, multifactor situation, the finding of differences between natives and immigrants in the same region suggests the need to investigate the causes in greater depth and to introduce new strategies and interventions in this population group.

Análisis comparativo de las serologías realizadas a los inmigrantes en la región sanitaria de Lleida

OBJECTIVE Evaluate the process of screening and detection of HIV, HBV, HCV and syphilis in the province of Lleida by determining the proportions of positive results in the different groups during one year. DESIGN Descriptive, multicentre study of all the serological tests performed in immigrants and natives attended in 2007. SETTING Province of Lleida (Spain). PARTICIPANTS 255,410 users. MAIN MEASUREMENTS Age, sex, country of origin and period of residence in Spain, and the results for HIV, hepatitis B, hepatitis C and syphilis. We calculated the proportions in which a serological test had been requested, and examined the association between the rates of positive tests and the geographical area of origin, and calculated age-adjusted rates taking the age distribution of the native population as the reference. RESULTS Risk of HBV was 4.6 times higher in immigrants than in natives (11.7 times in sub-Saharan Africans). The rate of positive syphilis tests was three times higher in the immigrant group. For HIV the PR was 2.3 (sub-Saharan Africans 7.4). For hepatitis C the risk was lower in immigrants than in natives (PR=0.4). CONCLUSIONS Immigrants have a higher probability of testing positive in screening in hepatitis B, syphilis and HIV. The rates differ significantly according to the origin of the immigrant.

Three-vessel myocardial bridging: A possible cause of myocardial stunning

The authors report a rare clinical case of myocardial bridging of the three major coronary arteries, which manifested in an unusual way with severe biventricular dysfunction in the context of tachycardia. For the diagnosis, the authors relied on non-invasive multimodality cardiac imaging, including cardiac magnetic resonance, computed tomography angiography and myocardial perfusion scintigraphy. The implementation of targeted medical and neurohormonal therapy resulted in the recovery of ventricular function and clinical improvement.
