Information About Donation and Organ Transplantation Among Spanish Medical Students.

INTRODUCTION: Health professionals are asked to promote health, especially organ transplantation; however, they do not always have specific training. OBJECTIVE: To analyze information about donation and organ transplantation among Spanish medical students. METHOD: The population under study is medical students in Spanish universities using the database of the International Donor Collaborative Project, stratified by geographic area and academic year (n = 9275). The instrument used is the attitude questionnaire for organ donation for "PCID-DTO-Ríos" transplantation, validated with an explained variance of 63.203% and α = 0.834. The Student t test was applied together with the χ2 test, complemented by an analysis of the remainders, and Fisher's exact test was applied. RESULTS: Of the students, 74% indicate that they have received information from university professors about organ transplant. Concerning specific issues with the donation, it is notable that only 66.7% (n = 6190) know and accept the concept of brain death as the death of a person. However, only 22% consider themselves as having good information, and 35.3% indicate that their information is scarce or void. Students indicate having received information about transplant from other extra-university sources, such as television and Internet (80.9%), books and magazines (73.2%), and the press (66.9%). From the information obtained in the sociofamilial field, 60.7% have obtained information from the family and 58.1% from friends. Of this information, 9% has been negative from friends, 7.5% from family, 6% from the Internet and television, and 4% from university professors. CONCLUSION: Spanish medical students believe they have little information about organ transplantation and have received negative information.

Are Medical Students of Non-Spanish Nationality Studying in Spain as Sensitized to Transplantation as Those of Spanish Nationality?

INTRODUCTION: Awareness of organ donation among Spanish doctors and medical students is very positive. However, the emerging group of professionals of non-Spanish nationality studying in Spain has not been analyzed. OBJECTIVE: To analyze the differences in the attitudes toward the different types of donation among medical students, according to their nationality. METHODS: The population under study is medical students in Spanish universities using the database of the International Collaborative Donor Project, stratified by geographic area and academic year. Groups under study include students of non-Spanish nationality as group 1 (n = 1570) and students of Spanish nationality as Group 2 (n = 7705). Instruments are validated questionnaires of attitude toward donation "PCID-DTO-Ríos," "PCID-DVR-Ríos," "PCID-DVH-Ríos," and "PCID-XenoTx-Ríos." RESULTS: The attitude toward the donation of own organs after death is similar in both groups (P = .703). Non-Spaniards are 79.2% in favor compared to 79.6% of Spaniards. Living kidney donation, both unrelated (33.3% vs 29.3% in favor; P = .001) and related (91.2% vs 89, 6% in favor; P = .047), is more favorable among non-Spanish students. There are no differences regarding non-related living liver donation (29.7% vs 29.3% in favor; P = .063), but there are differences in the results for related living liver donation (94.1% vs 88%; P < .001). The attitude toward xenotransplantation of organs is similar (80.8% vs 80.8%; P = .999). CONCLUSIONS: Awareness of the donation of organs among Spanish medical students is similar to non-Spanish students studying in Spain, except the attitude toward living donation.

What Reasons Lead Spanish Medical Students Not to Be in Favor of Organ Donation?

INTRODUCTION: Despite sensitization of medical students toward the donation of organs, a non-negligible percentage of students are not in favor of donation. OBJECTIVE: To analyze the reasons of Spanish medical students who do not have a favorable attitude toward the donation of their own organs after death. METHOD: The population under study is medical students in Spanish universities, using the database of the International Donor Collaborative Project, stratified by geographic area and academic year. The questionnaire completion was anonymous and self-administered. The study group is medical students with an unfavorable attitude toward organ donation. The assessment instrument used is a validated questionnaire of attitude toward the donation of organs for transplant, "PCID-DTO-Ríos." The reasons against the donation are valued in the questionnaire through a question. RESULTS: Of the participants included in the PCID, students who are not in favor of organ donation were selected (n = 1899). Of them, 8.1% (n = 154) are against and 91.1% (n = 1745) are doubtful. The main reasons indicated are the fear of apparent death in 11.4% of respondents, fear of possible mutilation after donation in 11.1%, and religious reasons in 2.6%. Of those, 6.9% indicate other reasons but do not clearly specify the reasons, using words such as "fear" (2.5%) or "doubts about the process" (4.1%); 66.2% (n = 1257) indicated an "assertive refusal" ("I don't want to express my reasons"). CONCLUSION: Twenty percent of Spanish medical students are not in favor of donating their organs and are not in favor of showing their reasons.

Do Religious Factors Influence the Attitude Toward Organ Donation Among Medical Students? A Spanish Multicenter Study.

INTRODUCTION: Religious factors have conditioned the attitude toward organ donation and transplantation (ODT) since the beginning of transplantation, despite the fact that most religions are in favor of transplantation. OBJECTIVE: To assess the impact of religious beliefs of medical students on their attitude toward ODT. METHOD: Population under study: Medical students in Spanish universities. STUDY SAMPLE: Stratified by geographical area and academic course. Assessment instrument: Attitude ODT questionnaire PCID-DTO-Ríos, anonymous and self-administered. RESULTS: Of all students, 42% (n = 3907) declare themselves atheists or agnostics. The remaining 58% (n = 5368) declare themselves to be religious, the majority being Catholic (55%, n = 5102). Of the rest, 0.2% are Muslims (n = 8), 0.1% Protestants (n = 1), and the remaining 2.7% (n = 257) indicate other religious doctrines but do not want to specify it. Regarding their attitude toward ODT, those who consider themselves atheists or agnostics have a more favorable attitude than those who consider themselves religious (84% versus 76%; P < .001). Among those who follow some kind of religion, Catholics are more in favor of ODT than non-Catholics (77% vs 64%, P < .001). Note that among the religious, only 57% (n = 3050) know which religion is in favor of transplantation, while 22% (n = 1,152) consider that it has not been pronounced on the matter, 13% (n = 723) think the religion is against donation, and the remaining 8% (n = 443) do not know. CONCLUSION: The religion professed by medical students conditions their attitude toward donation, with the atheists and agnostics being more in favor of donation.

Are High Rates of Deceased Donation Conditioning the Attitude Toward Liver Donation Among Medical Students?

The involvement of health professionals from their training period is important for the promotion of living liver donation. There are data that indicate that the awareness of living donation is lower in areas with high rates of deceased donation. OBJECTIVE: To analyze the attitude toward living liver donation among Spanish medical students, according to donation rates of their regions. METHOD: Population under study: Medical students in Spanish universities. Database of the Collaborative International Donor Project, stratified by geographic area and academic course. The completion was anonymous and self-administered. Groups under study: group 1 (n = 1136): students in universities of regions with >50 donors per million population (pmp); group 2 (n = 2018): students in region universities with <40 donors pmp. Assessment instrument: the attitude questionnaire for living liver donation Proyecto Colaborativo Internacional Donante sobre Donación de Vivo Hepático-Ríos (PCID-DVH Ríos). RESULTS: The attitude toward related liver donation is more favorable among the students of regions with <40 donors pmp than among those of >50 donors pmp. Thus, in group 1, a total of 88% (n = 1002) of students are in favor compared with 91% (n = 1831) of group 2 (P=.02). The psychosocial profile of each study group about their attitude toward living related liver donation is analyzed. There is a similar profile between the 2 groups, although there are differences in some variables such as age, a belief that one might need a transplant, family discussion about donation and transplantation, discussion with friends about donation and transplantation, and knowing about a donor. CONCLUSIONS: The awareness of living related donation among Spanish medical students is greater among the regions with lower organ donation rates.

Sensitization Toward Organ Donation Among Medical Students in Spanish Regions With More Than 50 Donors Per Million Population.

The awareness of organ donation among health professionals is important at the time of transplant promotion. In this sense, the training and awareness of the professionals in training is fundamental. OBJECTIVE: To analyze the differences in the attitude toward organ donation and the factors that condition it among medical students of regions with donation rates >50 donors per million population (pmp) with respect to those with rates <40 donor pmp. METHOD: Population under study: medical students in Spanish universities. Database of the Collaborative International Donor Project, stratified by geographic area and academic course. The completion was anonymous and self-administered. Groups under study: Group 1 (n = 1136): students in universities of regions with >50 donors pmp. Group 2 (n = 2018): university students in regions with <40 donors pmp. Assessment instrument: attitude questionnaire for organ donation for transplant PCID-DTO-Ríos. RESULTS: The attitude toward organ donation for transplantation is similar among students from the autonomous communities with >50 donors pmp and with <40 donors pmp. In group 1, 79% (n = 897) of students are in favor compared with 81% (n = 1625) of group 2 (P=.29). The psychosocial profile toward donation is similar in both groups relating to the following variables (P < .05): sex, having discussed transplantation with family and as a couple, considering the possibility of needing a transplant, involvement in prosocial activities, attitude toward the manipulation of corpses, knowledge of the brain death concept, and religion. CONCLUSIONS: The awareness of organ donation in Spanish medical students is quite homogeneous and is not related to the local donation rates of each region.

A Multicentre and stratified study of the attitude of medical students towards organ donation in Spain.

INTRODUCTION: Medical students represent a new generation of medical thought, and if they have a favourable attitude towards organ donation this will greatly encourage its promotion. OBJECTIVE: To analyse the attitude of medical students in Spanish universities towards the donation of their own organs and to determine the factors affecting this attitude. MATERIAL AND METHODS: Type of study: A sociological, interdisciplinary, multicentre, and observational study in Spain. STUDY POPULATION: Students studying a degree in medicine enrolled in Spain (n = 34,000). SAMPLE SIZE: A sample of 9598 students (confidence of 99% and precision of ±1%), stratified by geographical area and academic year. Instrument of measurement: A validated questionnaire of attitude towards organ donation and transplantation (PCID-DTO RIOS) was self-administered and completed anonymously. RESULTS: The questionnaire completion rate was 95.7% (n = 9.275). 80% were in favour of donation, 2% against and 18% were undecided. The following main variables were related to a favourable attitude: being of the female sex (Odds Ratio = 1.739); being in the sixth year of the degree (OR = 2.506); knowing a donor (OR = 1.346); having spoken about the subject with one's family (OR = 2.132) and friends (OR = 1.333); having a family circle that is in favour, more specifically, having a father (OR = 1.841), mother (OR = 2.538) or partner in favour (OR = 2.192); being a blood donor (OR = 2.824); acceptance of the mutilation of the body if it were necessary (OR = 2.958); and being an atheist or an agnostic (OR = 1.766). CONCLUSIONS: Spanish medical students generally have a favourable attitude towards organ donation, although 20% are not in favour.

Do Spanish Medical Students Understand the Concept of Brain Death?

OBJECTIVE: To analyze the level of understanding of the brain death concept among medical students in universities in Spain. METHODS: This cross-sectional sociological, interdisciplinary, and multicenter study was performed on 9598 medical students in Spain. The sample was stratified by geographical area and academic year. A previously validated self-reported measure of brain death knowledge (questionnaire Proyecto Colaborativo Internacional Donante sobre la Donación y Transplante de Organos) was completed anonymously by students. RESULTS: Respondents completed 9275 surveys for a completion rate of 95.7%. Of those, 67% (n = 6190) of the respondents understood the brain death concept. Of the rest, 28% (n = 2652) did not know what it meant, and the remaining 5% (n = 433) believed that it did not mean that the patient was dead. The variables related to a correct understanding of the concept were: (1) being older ( P < .001), (2) studying at a public university ( P < .001), (3) year of medical school ( P < .001), (4) studying at one of the universities in the south of Spain ( P = .003), (5) having discussed donation and transplantation with the family ( P < .001), (6) having spoken to friends about the matter ( P < .001), (7) a partner's favorable attitude toward donation and transplantation ( P < .001), and (8) religious beliefs ( P < .001). CONCLUSIONS: Sixty-seven percent of medical students know the concept of brain death, and knowledge improved as they advanced in their degree.

Medical students faced with related and unrelated living kidney donation: a stratified and multicentre study in Spain.

INTRODUCTION: The attitude of medical students towards living kidney donation (LKD) is of great interest given that they will become promoters of this technique in the near future. OBJECTIVE: To analyse the attitude of Spanish medical students towards related and unrelated LKD and to determine the factors affecting this attitude. MATERIALS AND METHODS: Type of study: A sociological, interdisciplinary, multicentre, and observational study. STUDY POPULATION: Medical students enrolled in Spain (n = 34.000). SAMPLE SIZE: A sample of 9598 students (99 % confidence and precision of ±1 %), stratified by geographical area and academic year. Measurement instrument: A validated questionnaire (PCID-DVR RIOS) was administered and completed anonymously. RESULTS: There was a completion rate of 95.7 % (n = 9275); 93 % (n = 8630) were in favour of related LKD, and 30 % (n = 2784) were in favour of unrelated LKD. The following factors were associated with this attitude: (1) age (p = 0.008); (2) sex (p < 0.001); (3) year of university degree (p < 0.001); (4) a belief that a transplant might be necessary in the future (p < 0.001); (5) attitude towards deceased organ donation (p < 0.001); (6) a willingness to accept a kidney from a living donor (p < 0.001); (7) attitude towards living liver donation (p < 0.001); (8) a partner's attitude towards donation (p < 0.001); (9) having spoken about the subject with one's family (p < 0.001), or friends (p < 0.001); (10) pro-social behaviour (p < 0.001); (11) the respondent's religious attitude (p < 0.001); and (12) fear of possible mutilation of the body after donation (p < 0.001). CONCLUSIONS: The attitude of medical students towards LKD is very favourable when it is the related kind of donation, and it is associated with factors of general knowledge about organ donation and transplantation and social interaction and religion.

Evaluación de la autoestima en varones con disfunción eréctil tratados con sildenafilo. Análisis de un grupo de pacientes españoles procedentes de un estudio multicéntrico internacional / Evaluation of self-esteem in males with erectile dysfunction treated with viagra. Analysis of a Spanish patients group selected from a multicenter, international study

Introducción y objetivos: La disfunción eréctil (DE) provoca alteraciones psicológicas, principalmente ansiedad y pérdida de la autoestima. Intentamos conocer los cambios emocionales, basados en la autoestima y las relaciones, en un grupo de varones españoles con DE tras el tratamiento con sildenafilo, utilizando para ello el cuestionario SEAR (Self-Esteem And Resationship). Material y método: De un estudio internacional multicéntrico, randomizado, grupos paralelos, doble ciego y controlado por placebo de sildenafilo diseñado para evaluar la autoestima y relaciones en varones con DE, seleccionamos los pacientes reclutados en España. Se compararon los cambios en los diferentes dominios del cuestionario SEAR (autoestima, actividad sexual, autoconfianza y relaciones generales) que se administró antes y después del tratamiento, así como los diferentes dominios del IIEF. También se calculó la correlación entre el cambio en el dominio autoestima del cuestionario SEAR y el dominio función eréctil del IIEF. El estudio estadístico se basó en un análisis de la covarianza del cambio en las puntuaciones y en un estudio de correlación. Resultados: El grupo español de investigadores incluyó 119 pacientes. La puntuación del dominio función eréctil mostró una mejoría significativamente mayor para el grupo de sildenafilo. La diferencia de cambio en la media de la puntuación total del SEAR tras el tratamiento fue de 16,9 (IC 95%: 8,9; 24,8) a favor de sildenafilo respecto al placebo (p=0,0001), con una mejoría en la puntuación significativamente superior en todos los dominios del SEAR a favor de sildenafilo. Se observó una correlación significativa entre los cambios en el dominio de autoestima del SEAR y el dominio función eréctil del IIEF para ambos grupos de tratamiento. Conclusiones: Se confirma una mejoría emocional en los pacientes tratados con sildenafilo en base a la mejora en la autoestima, autoconfianza y las relaciones. Variaciones en el dominio función eréctil del IIEF muestran correlación con las del dominio autoestima del SEAR (AU)

Introduction and objectives: Erectile dysfunction (ED) leads to psychological disturbances, especially anxiety and loss of self-esteem. We try to understand the emotional changes, based on self-esteem and relationships in a group of Spanish men with ED after sildenafil treatment, with the use of the SEAR questionnaire (Self-Esteem And Relationship). Materials and methods: The patients recruited in Spain, where selected from an international, multicenter, randomized, parallel-group, double-blind, placebo-controlled, sildenafil study designed to assess self-esteem and relationships in men with ED. We compared the changes in the different domains of the SEAR questionnaire (Self-steem, sexual activity, self-confidence and general relationships) that was administered before and after treatment; the different domains of the IIEF was evaluated aswell. We also calculated the correlation between changes in self-esteem domain of the SEAR questionnaire. The statistical study was based on an analysis of covariance of change in scores and a correlation analysis. Results: The Spanish group of researchers included 119 patients. The erectile function domain score showed significantly greater improvement for the group of sildenafil. The difference in change in total mean score of the SEAR after treatment was 16.9 (95% CI 8.9, 24.8) for sildenafil over placebo (p=0.0001), with a significantly higher score improvement in all the domains of the SEAR for Sildenafil. There was a significant correlation between the changes in the domain of self-esteem of the SEAR and the IIEF erectile function domain for both treatment groups. Conclusions: Emotional improvement was confirmed in patients treated with sildenafil based on improved self-esteem, self-confidence and relationships. Changes in the IIEF erectile function domain correlate with the SEAR self-esteem domain (AU)

Development of the 25-item National Eye Institute Visual Function Questionnaire.

OBJECTIVE: To develop and test the psychometric properties of a 25-item version of the National Eye Institute Visual Function Questionnaire (NEI VFQ-25). DESIGN: Prospective observational cohort study of persons with 1 of 5 chronic eye diseases or low vision who were scheduled for nonurgent visits in ophthalmology practices and a reference sample of persons without eye disease. SETTING: Eleven university-based ophthalmology practices and the NEI Clinical Center. PATIENTS: Eligible participants had to have 1 of the following eye conditions: age-related cataracts, age-related macular degeneration, diabetic retinopathy, primary open-angle glaucoma, cytomegalovirus retinitis, or low vision from any cause. Seven of the 12 sites also enrolled persons in a reference sample. Reference sample participants had no evidence of underlying eye disease but were scheduled for either screening eye examinations or correction of refractive error. All eligible persons had to be 21 years or older, English speaking, and cognitively able to give informed consent and participate in a health status interview. MEASUREMENTS AND MAIN RESULTS: To provide the data needed to create the NEI VFQ-25, all subjects completed an interview that included the 51-item NEI VFQ. Estimates of internal consistency indicate that the subscales of the NEI VFQ-25 are reliable. The validity of the NEI VFQ-25 is supported by high correlations between the short- and long-form versions of the measure, observed between-group differences in scores for persons with different eye diseases of varying severity, and the moderate-to-high correlations between the NEI VFQ-25 subscales that have the most to do with central vision and measured visual acuity. CONCLUSIONS: The reliability and validity of the NEI VFQ-25 are comparable to those of the 51-item NEI VFQ field test version of the survey. This shorter version will be more feasible in settings such as clinical trials where interview length is a critical consideration. In addition, preliminary analyses indicate that the psychometric properties of the NEI VFQ-25 are robust for the eye conditions studied; this suggests that the measure will provide reproducible and valid data when used across multiple conditions of varying severity.

[Reference values for lead in blood in urban population in southern Brazil]. / Valores de referência para plumbemia em uma população urbana do Sul do Brasil.

OBJECTIVE: To describe the reference values for lead in blood in an urban population in the city of Londrina, in the state of Paraná, Brazil. MATERIALS AND METHODS: The reference population was composed of 520 adult volunteers who were assessed from November 1994 to December 1996. Exclusion criteria were: occupational exposure to lead, exposure through personal habits or practices, smoking more than 10 cigarettes per day, and living near industrial plants or other places that use lead in their production processes. Also excluded were individuals with abnormal clinical or laboratory results or with chronic diseases or cardiovascular disorders. Lead blood levels were determined using air-acetylene flame atomic absorption spectrophotometry. The detectable limit was 1.23 micrograms/dL. After the analyses of lead in blood, the following values were determined: minimum value, first quartile, median, third quartile, and maximum value; geometric mean; 95% confidence interval; experimental interval; and reference value. RESULTS: The reference values for lead in blood ranged from 1.20 micrograms/dL to 13.72 micrograms/dL. The geometric mean was 5.5 micrograms/dL. CONCLUSIONS: In general, the values found in this study are lower than those that have been reported for other countries. Additional data should be gathered from Brazilian populations living in more-industrialized areas.

Modifiable risk factors predict functional decline among older women: a prospectively validated clinical prediction tool. The Study of Osteoporotic Fractures Research Group.

OBJECTIVE: To identify modifiable predictors of functional decline among community-residing older women and to derive and validate a clinical prediction tool for functional decline based only on modifiable predictors. DESIGN: A prospective cohort study. SETTING: Four geographic areas of the United States. PARTICIPANTS: Community-residing women older than age 65 recruited from population-based listings between 1986 and 1988 (n = 6632). MEASUREMENTS: Modifiable predictors were considered to be those that a clinician seeing an older patient for the first time could reasonably expect to change over a 4-year period: benzodiazepine use, depression, low exercise level, low social functioning, body-mass index, poor visual acuity, low bone mineral density, slow gait, and weak grip. Known predictors of functional decline unlikely to be amenable to intervention included age, education, medical comorbidity, cognitive function, smoking history, and presence of previous spine fracture. All variables were measured at baseline; only modifiable predictors were candidates for the prediction tool. Functional decline was defined as loss of ability over the 4-year interval to perform one or more of five vigorous or eight basic daily activities. RESULTS: Slow gait, short-acting benzodiazepine use, depression, low exercise level, and obesity were significant modifiable predictors of functional decline in both vigorous and basic activities. Weak grip predicted functional decline in vigorous activities, whereas long-acting benzodiazepine use and poor visual acuity predicted functional decline in basic activities. A prediction rule based on these eight modifiable predictors classified women in the derivation set into three risk groups for decline in vigorous activities (12%, 25%, and 39% risk) and two risk groups for decline in basic activities (2% and 10% risk). In the validation set, the probabilities of functional decline were nearly identical. CONCLUSIONS: A substantial portion of the variation of functional decline can be attributed to risk factors amenable to intervention over the short term. Using eight modifiable predictors that can be identified in a single office visit, clinicians can identify older women at risk for functional decline.

Influence of age-related maculopathy on visual functioning and health-related quality of life.

PURPOSE: To describe the influence of age-related maculopathy on visual functioning and health-related quality of life. METHODS: A prospective, cross-sectional, observational cohort sample of 201 persons with various stages of age-related maculopathy was recruited from the Massachusetts Eye and Ear Infirmary as part of a longitudinal study of age-related macular degeneration. Persons were considered to have age-related maculopathy if one or more of the following clinical characteristics were present: drusen, retinal pigment epithelial changes, geographic atrophy, or evidence of exudative disease. Median corrected visual acuity for this sample was 20/25 in the better eye, with all subjects having 20/200 or better visual acuity in at least one eye at baseline. All participants underwent a comprehensive ophthalmologic examination with a dilated pupil. In addition to the usual clinical data collection, severity of age-related maculopathy was graded by an ophthalmologist who used standard clinical criteria and was masked to the participants' descriptions of visual functioning and health-related quality of life. All participants completed an interview that included the Activities of Daily Vision Scale, a survey designed to assess difficulties with routine daily activities that require vision, and the Short Form-36 Health Survey, a generic measure of multidimensional health-related quality of life. RESULTS: Severity of age-related maculopathy was associated with poorer scores of the Activities of Daily Vision Scale. This association was most significant for near vision and driving activities. In this sample, the SF-36 Health Survey scales were not significantly correlated with severity of age-related maculopathy. CONCLUSIONS: Reported visual functioning is significantly associated with the clinical severity of age-related maculopathy. However, once visual acuity is taken into consideration, clinical grading of age-related maculopathy did not explain a significant portion of the variation in visual functioning. The lack of significant correlation between severity of age-related maculopathy and the SF-36 Health Survey may have resulted from the small number of participants in our sample with severe bilateral age-related maculopathy.

Age-related differences in management of heart disease: a study of cardiac medication use in an older cohort. Pacemaker Selection in the Elderly (PASE) Investigators.

BACKGROUND: Previous studies have suggested suboptimal use of cardiac medications for secondary prevention after myocardial infarction (MI) and atrial fibrillation (AF), especially among older people. OBJECTIVE: To determine whether patients older than 75 years are less likely than those aged 65 to 74 to be prescribed medications with evidence-based indications, including angiotensin-converting enzyme (ACE) inhibitors for left ventricular dysfunction (LVD) and/or diabetes mellitus (DM), aspirin and/or beta-blockers for those with a history of MI, and warfarin for chronic AF. DESIGN: A retrospective cohort study. SETTING: Twenty-nine hospitals, predominantly tertiary-care institutions. PARTICIPANTS: A total of 407 patients randomized to ventricular or dual-chamber pacing from February 26, 1993, to September 30, 1994, in the Pacemaker Selection in the Elderly (PASE) trial. MEASUREMENTS: A review of the patient's medical history and a physical exam at study enrollment, three follow-up timepoints, and a study closeout. RESULTS: Patients older than 75 years with LVD and/or DM were less likely to be prescribed ACE inhibitors (OR = .56 (0.31-1.00)); patients older than 75 with a history of MI were less likely to be taking aspirin (OR = .43 (0.19-.95)), and patients older than 75 with AF were less likely to be prescribed warfarin (OR = .18 (0.05-.61)). Patients older than 75 years of age with any or all of the conditions studied were less likely to be prescribed indicated medications than those ages 65 to 74 (OR = .35 (0.18-.70)), after controlling for between-group differences in comorbidity, gender, and number of noncardiac medications. CONCLUSION: Older age is a significant independent negative correlate of evidence-based cardiac medication use in this cohort. Causes for this finding need to be explored.

[Reference values for lead levels in blood for the urban population]. / Valores de referência para plumbemia em população urbana.

INTRODUCTION: The lead reference values for blood used in Brazil come from studies conducted in other countries, where socioeconomic, clinical, nutritional and occupational conditions are significantly different. In order to guarantee an accurate biomonitoring of the population which is occupationally exposed to lead, a major health concern of the studied community, reference values for individuals who are not occupationally exposed and who live in the southern region of the city were established. MATERIAL AND METHOD: The sample was composed of 206 subjects of at least 15 years of age. Various strategies were employed to assure good-quality sampling. Subjects who presented values outside clinical or laboratory norms were excluded, as well as those whose specific activities might interfere with the results. RESULTS: Lead reference values for blood were found to be from 2.40 to 16.6 micrograms.dL-1, obtained by the interval x +/- 2s (where x is the mean and s is the standard deviation form observed values) and the median was 7.9 micrograms.dL-1.
