[Can primary health care strengthen the right to adequate food as a human right in Latin America?¿Cómo la atención primaria de salud puede fortalecer la alimentación adecuada como derecho en América Latina?] / Como a atenção primária à saúde pode fortalecer a alimentação adequada enquanto direito na América Latina?

Forty years ago, the Declaration of Alma-Ata emphasized health as a human right, introduced primary health care (PHC) as a strategy to attain an acceptable level of health for all, and included the issue of food and nutrition as an integral part of PHC. The right to adequate food (RAF) is closely related to the right to health, since it is essential to ensure dignified living conditions that promote health. The historical peculiarities and the political and economic position of Latin America constitute barriers for the full realization of human rights, and especially social rights. In this sense, the present article aims to explore the modes by which PHC services can leverage the RAF in Latin America. In addition, the article describes measures that exemplify how countries can strengthen RAF through PHC. Finally, the text seeks to recover the emancipatory potential of PHC through a vision of human rights enforcement beyond the right to health. The overview shows that PHC has the capacity to fulfill human rights that are interdependent on health in the Latin American context.

Hace 40 años, la Declaración de Alma-Ata reforzó la salud como derecho humano, presentó la atención primaria de salud (APS) como camino para alcanzar un grado de salud aceptable para todos e incorporó la alimentación y nutrición como parte de los cuidados primarios en salud. El derecho humano a la alimentación adecuada (DHAA) está íntimamente relacionado con el derecho a la salud, pues es un requisito indispensabel para la existencia de condiciones dignas para promover la salud. Las particularidades históricas y la posición político-económica de América Latina representan barreras para la promoción plena de los derechos humanos, y especialmente de los derechos sociales. En este sentido, el objetivo de este artículo es explorar la manera como los servicios de APS pueden impulsar el DHAA en América Latina. Adicionalmente, se presentan medidas que ejemplifican cómo los países pueden fortalecer el DHAA a partir de la APS. Finalmente, el texto se propone rescatar el potencial emancipatorio de la APS en América Latina vislumbrando su actuación en la promoción de derechos humanos más allá del derecho a la salud. El panorama presentado demuestra la capacidad de respuesta de la APS para hacer efectivos los derechos humanos interdependientes de la salud en el contexto latinoamericano.

Uncited articles in Brazilian public health journals.

Here, we describe the percentage of non-citation in Brazilian public health journals, a field that, until now, had not been investigated nationally or internationally. We analyzed articles, published between 2008 and 2012, of eight public health journals indexed in the scopus database. The percentage of non-citation differs between journals (from 5.7% to 58.1%). We identified four statistically distinct groups: História, Ciência, Saúde - Manguinhos (58% uncited articles); Physis: Revista de Saúde Coletiva, Interface, and Saúde e Sociedade (32% to 37%); Ciência & Saúde Coletiva and Revista Brasileira de Epidemiologia (16% to 17%); and Cadernos de Saúde Pública and Revista de Saúde Pública (6%). The non-citation in the first three years post-publication also varies according to journal. Four journals have shown a clear decline of non-citation: Cadernos de Saúde Pública, Ciência & Saúde Coletiva, Revista Brasileira de Epidemiologia, and Physis. Another three (Revista de Saúde Pública, Saúde e Sociedade, and Interface) presented an oscillation in non-citation, but the rates of 2008 and 2012 are similar, with different magnitudes. In turn, the journal História, Ciência, Saúde - Manguinhos maintains high rates of non-citation. Multidisciplinary journals attract more citation, but a comprehensive citation model still needs to be formulated and tested.

Individual- and contextual-level factors associated with client-initiated HIV testing.

BACKGROUND: Knowing the reasons for seeking HIV testing is central for HIV prevention. Despite the availability of free HIV counseling and testing in Brazil, coverage remains lacking. METHODS: Survey of 4,760 respondents from urban areas was analyzed. Individual-level variables included sociodemographic characteristics; sexual and reproductive health; HIV/AIDS treatment knowledge and beliefs; being personally acquainted with a person with HIV/AIDS; and holding discriminatory ideas about people living with HIV. Contextual-level variables included the Human Development Index (HDI) of the municipality; prevalence of HIV/AIDS; and availability of local HIV counseling and testing (CT) services. The dependent variable was client-initiated testing. Multilevel Poisson regression models with random intercepts were used to assess associated factors. RESULTS: Common individual-level variables among men and women included being personally acquainted with a person with HIV/AIDS and age; whereas discordant variables included those related to sexual and reproductive health and experiencing sexual violence. Among contextual-level factors, availability of CT services was variable associated with client-initiated testing among women only. The contextual-level variable "HDI of the municipality" was associated with client-initiated testing among women. CONCLUSION: Thus, marked gender differences in HIV testing were found, with a lack of HIV testing among married women and heterosexual men, groups that do not spontaneously seek testing.

Short and long-term immunogenicity and safety following the 23-valent polysaccharide pneumococcal vaccine in juvenile idiopathic arthritis patients under conventional DMARDs with or without anti-TNF therapy.

OBJECTIVES: To assess immunogenicity and safety of the 23-valent polysaccharide pneumococcal vaccine (PPV23) in juvenile idiopathic arthritis (JIA) patients under conventional DMARDs with or without anti-TNF therapy. The influences of demographic data, disease activity and treatment on immune response and the potential deleterious effects of vaccine on disease itself were also evaluated. METHODS: 17 JIA patients immediately pre-etanercept (Group 1) and 10 JIA patients on stable dose of methotrexate (Group 2) received one dose of PPV23. All patients were evaluated pre-vaccination, 2 months and 12 months post-vaccination for seven pneumoccocal serotypes. Serology was performed by enzyme immunoassay and the immunogenicity endpoints included seroprotection (SP), seroconversion (SP) and geometric mean concentration of antibodies(GMC). Clinical and laboratorial parameters of JIA were evaluated before and after vaccination. RESULTS: Groups 1 and 2 were comparable regarding age, gender, disease duration and other DMARDs use (p>0.05). Pre-immunization SP and GMC were alike in patients with and without anti-TNF therapy (p>0.05). The frequencies of patients achieving adequate vaccine response (seroconversion in ≥50% of all serotypes) at 2 months (53 vs. 30%, p=0.424) and 12 months (36 vs. 40%, p=1.0) were similar in JIA patients with and without anti-TNF therapy. Further comparison of patients with and without adequate response at 2 months revealed no influence of demographic, clinical and laboratorial JIA parameters (p>0.05). Serious adverse events were not observed. CONCLUSIONS: Anti-TNF therapy in JIA patients does not seem to have an additional deleterious effect on short/long-term PPV23 immunogenicity compared to MTX alone and no influence on disease parameters was observed with this vaccine.

Information literacy: perceptions of Brazilian HIV/AIDS researchers.

BACKGROUND: Information literacy has evolved with changes in lifelong learning. Can Brazilian health researchers search for and use updated scientific information? OBJECTIVES: To describe researchers' information literacy based on their perceptions of their abilities to search for and use scientific information and on their interactions with libraries. METHODS: Semi-structured interviews and focus group conducted with six Brazilian HIV/AIDS researchers. Analyses comprised the assessment of researchers as disseminators, their interactions with librarians, their use of information and communication technology and language. RESULTS: Interviewees believed they were partially qualified to use databases. They used words and phrases that indicated their knowledge of technology and terminology. They acted as disseminators for students during information searches. Researchers' abilities to interact with librarians are key skills, especially in a renewed context where libraries have, to a large extent, changed from physical spaces to digital environments. DISCUSSION: Great amounts of information have been made available, and researchers' participation in courses does not automatically translate into adequate information literacy. Librarians must help research groups, and as such, librarians' information literacy-related responsibilities in Brazil should be redefined and expanded. CONCLUSIONS: Students must develop the ability to learn quickly, and librarians should help them in their efforts. Librarians and researchers can act as gatekeepers for research groups and as information coaches to improve others' search abilities.

TNF blockers show distinct patterns of immune response to the pandemic influenza A H1N1 vaccine in inflammatory arthritis patients.

OBJECTIVE: To evaluate the immunogenicity of the anti-influenza A H1N1/2009 vaccine in RA and spondyloarthritis (SpA) patients receiving distinct classes of anti-TNF agents compared with patients receiving DMARDs and healthy controls. METHODS: One hundred and twenty patients (RA, n = 41; AS, n = 57; PsA, n = 22) on anti-TNF agents (monoclonal, n = 94; soluble receptor, n = 26) were compared with 116 inflammatory arthritis patients under DMARDs and 117 healthy controls. Seroprotection, seroconversion (SC), geometric mean titre, factor increase in geometric mean titre and adverse events were evaluated 21 days after vaccination. RESULTS: After immunization, SC rates (58.2% vs 74.3%, P = 0.017) were significantly lower in SpA patients receiving anti-TNF therapy, whereas no difference was observed in RA patients receiving this therapy compared with healthy controls (P = 0.067). SpA patients receiving mAbs (infliximab/adalimumab) had a significantly lower SC rate compared with healthy controls (51.6% vs 74.3%, P = 0.002) or those on DMARDs (51.6% vs 74.7%, P = 0.005), whereas no difference was observed for patients on etanercept (86.7% vs 74.3%, P = 0.091). Further analysis of non-seroconverting and seroconverting SpA patients revealed that the former group had a higher mean age (P = 0.003), a higher frequency of anti-TNF (P = 0.031) and mAbs (P = 0.001) and a lower frequency of MTX (P = 0.028). In multivariate logistic regression, only older age (P = 0.015) and mAb treatment (P = 0.023) remained significant factors for non-SC in SpA patients. CONCLUSION: This study revealed a distinct disease pattern of immune response to the pandemic influenza vaccine in inflammatory arthritis patients receiving anti-TNF agents, illustrated by a reduced immunogenicity solely in SpA patients using mAbs.

Glucocorticoid: major factor for reduced immunogenicity of 2009 influenza A (H1N1) vaccine in patients with juvenile autoimmune rheumatic disease.

OBJECTIVE: To assess the immunogenicity and safety of non-adjuvanted influenza A H1N1/2009 vaccine in patients with juvenile autoimmune rheumatic disease (ARD) and healthy controls, because data are limited to the adult rheumatologic population. METHODS: A total of 237 patients with juvenile ARD [juvenile systemic lupus erythematosus (JSLE), juvenile idiopathic arthritis (JIA), juvenile dermatomyositis (JDM), juvenile scleroderma, and vasculitis] and 91 healthy controls were vaccinated. Serology for anti-H1N1 was performed by hemagglutination inhibition assay. Seroprotection rate, seroconversion rate, and factor-increase in geometric mean titer (GMT) were calculated. Adverse events were evaluated. RESULTS: Age was comparable in patients and controls (14.8 ± 3.0 vs 14.6 ± 3.7 years, respectively; p = 0.47). Three weeks after immunization, seroprotection rate (81.4% vs 95.6%; p = 0.0007), seroconversion rate (74.3 vs 95.6%; p < 0.0001), and the factor-increase in GMT (12.9 vs 20.3; p = 0.012) were significantly lower in patients with juvenile ARD versus controls. Subgroup analysis revealed reduced seroconversion rates in JSLE (p < 0.0001), JIA (p = 0.008), JDM (p = 0.025), and vasculitis (p = 0.017). Seroprotection (p < 0.0001) and GMT (p < 0.0001) were decreased only in JSLE. Glucocorticoid use and lymphopenia were associated with lower seroconversion rates (60.4 vs 82.9%; p = 0.0001; and 55.6 vs 77.2%; p = 0.012). Multivariate logistic regression including diseases, lymphopenia, glucocorticoid, and immunosuppressants demonstrated that only glucocorticoid use (p = 0.012) remained significant. CONCLUSION: This is the largest study to demonstrate a reduced but adequate immune response to H1N1 vaccine in patients with juvenile ARD. It identified current glucocorticoid use as the major factor for decreased antibody production. The short-term safety results support its routine recommendation for patients with juvenile ARD.

[The sexuality of HIV-positive adolescents: rights and challenges for healthcare]. / A sexualidade de adolescentes vivendo com HIV: direitos e desafios para o cuidado.

Sexuality and reproductive healthcare represent relevant issues for comprehensive care of HIV-positive adolescents. However, public policies and health services give this issue insufficient attention. The scope of this article is to assess how HIV-positive young people and teenagers cope with their sexuality, dating and the urge to have children and start a family. In a qualitative study, in-depth interviews were staged with 21 HIV-positive (contracted by vertical, sexual or intravenous transmission) teenagers and 13 caregivers of children and youths living in Sao Paulo and Santos. The interviews revealed the different ways teenagers cope with their sexuality and with the anxiety of HIV disclosure in this context. Lack of information about HIV prevention, lack of support and skills to cope with their sexuality were revealed in the reports. Furthermore, stigma and discrimination were the most frequently reported difficulties. The main challenges to be faced in Brazil in regard to this issue are discussed, especially the need to consider HIV-positive youth as entitled to sexual rights. Recommendations are also made for incorporating the issue into a humanized and comprehensive care approach for HIV-positive children and young people.

Reduced seroprotection after pandemic H1N1 influenza adjuvant-free vaccination in patients with rheumatoid arthritis: implications for clinical practice.

BACKGROUND: Reduced response to pandemic (2009) H1N1 (pH1N1) vaccine in patients with rheumatoid arthritis (RA) was recently reported. OBJECTIVES: To evaluate the contribution of age, disease activity, medication and previous antibody levels to this reduced response. METHODS: 340 adult RA patients and 234 healthy controls were assessed before and 21 days after adjuvant-free influenza A/California/7/2009 (pH1N1) vaccine. Disease activity (DAS28), current treatment and pH1N1 antibody titres were collected. Seroprotection, seroconversion and factor increase in geometric mean titre (GMT) were calculated and adverse events registered. RESULTS: RA and controls showed similar (p>0.05) prevaccination GMT (8.0 vs 9.3) and seroprotection (10.8% vs 11.5%). After vaccination a significant reduction (p<0.001) was observed in all endpoints: GMT and factor increase in GMT, seroprotection and seroconversion rates. Disease activity did not preclude seroconversion or seroprotection and remained unchanged in 97.4% of patients. Methotrexate was the only disease-modifying antirheumatic drug associated with reduced responses (p=0.001). Vaccination was well tolerated. CONCLUSIONS: The data confirmed both short-term anti-pH1N1 vaccine safety and, different from most studies with seasonal influenza, reduced seroprotection in RA patients, unrelated to disease activity and to most medications (except methotrexate). Extrapolation of immune responses from one vaccine to another may therefore not be possible and specific immunisation strategies (possibly booster) may be needed. Clinicaltrials.gov no NCT01151644.

Immunogenicity and safety of the 2009 non-adjuvanted influenza A/H1N1 vaccine in a large cohort of autoimmune rheumatic diseases.

BACKGROUND: Despite the WHO recommendation that the 2010-2011 trivalent seasonal flu vaccine must contain A/California/7/2009/H1N1-like virus there is no consistent data regarding its immunogenicity and safety in a large autoimmune rheumatic disease (ARD) population. METHODS: 1668 ARD patients (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), ankylosing spondylitis (AS), systemic sclerosis, psoriatic arthritis (PsA), Behçet's disease (BD), mixed connective tissue disease, primary antiphospholipid syndrome (PAPS), dermatomyositis (DM), primary Sjögren's syndrome, Takayasu's arteritis, polymyositis and Granulomatosis with polyangiitis (Wegener's) (GPA)) and 234 healthy controls were vaccinated with a non-adjuvanted influenza A/California/7/2009(H1N1) virus-like strain flu. Subjects were evaluated before vaccination and 21 days post-vaccination. The percentage of seroprotection, seroconversion and the factor increase in geometric mean titre (GMT) were calculated. RESULTS: /st> After immunisation, seroprotection rates (68.5% vs 82.9% p<0.0001), seroconversion rates (63.4% vs 76.9%, p<0.001) and the factor increase in GMT (8.9 vs 13.2 p<0.0001) were significantly lower in ARD than controls. Analysis of specific diseases revealed that seroprotection significantly reduced in SLE (p<0.0001), RA (p<0.0001), PsA (p=0.0006), AS (p=0.04), BD (p=0.04) and DM (p=0.04) patients than controls. The seroconversion rates in SLE (p<0.0001), RA (p<0.0001) and PsA (p=0.0006) patients and the increase in GMTs in SLE (p<0.0001), RA (p<0.0001) and PsA (p<0.0001) patients were also reduced compared with controls. Moderate and severe side effects were not reported. CONCLUSIONS: The novel recognition of a diverse vaccine immunogenicity profile in distinct ARDs supports the notion that a booster dose may be recommended for diseases with suboptimal immune responses. This large study also settles the issue of vaccine safety. (ClinicalTrials.gov #NCT01151644).

Validity of the WHO VAW study instrument for estimating gender-based violence against women.

OBJECTIVE: To validate the instrument of the World Health Organization Violence Against Women (WHO VAW) study on psychological, physical and sexual violence against women perpetrated by intimate partners. METHODS: This was a cross-sectional study conducted in several countries between 2000 and 2003, including Brazil. Representative random samples of women aged 15-49 years with intimate partners were selected, living in the city of São Paulo (n = 940) and in the Zona da Mata, Pernambuco (n = 1,188), southeastern and northeastern regions, respectively. Exploratory factor analysis on questions relating to violence was performed (four psychological, six physical and three sexual questions), with varimax rotation and creation of three factors. Cronbach's alpha was calculated to analyze the internal consistency. To validate through extreme groups, mean scores (0 to 13 points) for violence were tested in relation to the following outcomes: self-rated health, daily activities, presence of discomfort or pain, suicidal ideation or attempts, heavy alcohol consumption and presence of common mental disorders. RESULTS: Three factors were defined, with similar accumulated variance (0.6092 in São Paulo and 0.6350 in the Zona da Mata). For São Paulo, the first factor was determined by physical violence, the second by sexual violence and the third by psychological violence. For the Zona da Mata, the first factor was formed by psychological violence, the second by physical violence and the third by sexual violence. Cronbach's alpha coefficients were 0.88 in São Paulo and 0.89 in the Zona da Mata. The mean scores for violence were significantly higher for less favorable outcomes, with the exception of suicide attempts in São Paulo. CONCLUSIONS: The instrument was shown to be adequate for estimating gender-based violence against women perpetrated by intimate partners and can be used in studies on this subject. It has high internal consistency and a capacity to discriminate between different forms of violence (psychological, physical and sexual) perpetrated in different social contexts. The instrument also characterizes the female victim and her relationship with the aggressor, thereby facilitating gender analysis.

Tuberculosis in hematopoietic stem cell transplant patients: case report and review of the literature.

The literature describing tuberculosis (TB) in hematopoietic stem cell transplant (HSCT) recipients is scant, even in countries where TB is common. We describe a case of pulmonary TB in a patient who underwent HSCT and review the English language literature on this subject. An extensive PubMed and Ovid search was undertaken for the period January 1980 to March 2009; the search terms used were 'Mycobacterium tuberculosis' or 'tuberculosis', in combination with 'hematopoietic stem cell transplantation' or 'bone marrow transplantation'. The patient in the present case report underwent allogeneic transplantation and developed TB 8 days after his HSCT. The patient had received vaccination against TB in childhood. During the year prior to the HSCT he had had contact with a relative who had pulmonary TB. On day 3 of anti-TB treatment he developed pericarditis. The patient received anti-TB treatment for 6 months without major problems. From the literature review, we found 34 related studies, 25 on the clinical manifestations of TB. Most of the reports were from Asia (48%), and the incidence of TB varied from 0.0014% in the USA to 16% in Pakistan. TB occurred at between +21 and +1410 days post-HSCT (257.2 days the median), and the lung was the organ most frequently involved. Mortality varied from 0% to 50% and was higher in allogeneic HSCT. There is no consensus regarding screening with the tuberculin skin test or primary prophylaxis for latent TB, and further research into this is necessary in developing countries with a high prevalence of TB.

Factors associated with sexual initiation and condom use among adolescents on Santiago Island, Cape Verde, West Africa.

The current study focuses on factors associated with sexual initiation and condom use among teenagers on Santiago Island, Cape Verde, according to gender. This was a representative, probabilistic sample of 13-to-17-year-olds (n = 768) attending public secondary schools on Santiago Island in 2007. Associations were tested by test of proportion, Pearson's chi-square, or Fisher's exact test and logistic regression. Factors related to sexual initiation among boys were: age over 14 years, Catholic religion, and alcohol consumption. For girls, the factors included: > 9 years of schooling and involvement in an affective-sexual relationship. Unlike other Sub-Saharan countries, this study showed a high prevalence of condom use during initial sexual activity. Adolescents are able to safely begin sexually active life if they have access to information, sex education, and other STD prevention and contraceptive methods. This study provides insights on the development of policies to reduce the vulnerability of the young population to STD/AIDS and the limits and challenges related to the promotion of condom use and sex education, focusing on unequal gender relations.

[Risk factors for early neonatal mortality]. / Fatores de risco para mortalidade neonatal precoce.

OBJECTIVE: To assess risk factors for early neonatal mortality. METHODS: A population-based case-control study was carried out with 146 early neonatal deaths and a sample of 313 controls obtained among survivals of the neonate period in the south region of the city of São Paulo, in the period of 8/1/2000 to 1/31/2001. Information was obtained through home interviews and hospital charts. Hierarchical assessment was performed in five groups with the following characteristics 1) socioeconomic conditions of mothers and families, 2) maternal psychosocial conditions, 3) obstetrical history and biological characteristics of mothers, 4) delivery conditions, 5) conditions of newborns RESULTS: Risk factors for early neonate mortality were: Group 1: poor education of household head (OR=1.6; 95% CI: 1.1;2.6), household located in a slum area (OR=2.0; 95% CI: 1.2;3.5) with up to one room (OR=2.2; 95% CI: 1.1;4.2); Group 2: mothers in recent union (OR=2.0; 95% CI: 1.0;4.2), unmarried mothers (OR=1.8; 95% CI: 1.1;3.0), and presence of domestic violence (OR=2.7; 95% CI: 1;6.5); Group 3: presence of complications in pregnancy (OR=8.2; 95% CI: 5.0;13.5), previous low birth weight (OR=2.4; 95% CI: 1.2;4.5), absence of pre-natal care (OR=16.1; 95% CI: 4.7;55.4), and inadequate pre-natal care (block 3) (OR=2.1; 95% CI: 2.0;3.5); Group 4: presence of clinical problems during delivery (OR=2.9; 95% CI: 1.4;5.1), mothers who went to hospital in ambulances (OR=3.8; 95% CI: 1.4;10.7); Group 5: low birth weight (OR=17.3; 95% CI: 8.4;35.6) and preterm live births (OR=8.8; 95% CI: 4.3;17.8). CONCLUSIONS: Additionally to proximal factors (low birth weight, preterm gestations, labor complications and unfavorable clinical conditions in gestation), the variables expressing social exclusion and presence of psychosocial factors were also identified. This context may affect the development of gestation and hinder the access of women to health services. Adequate prenatal care could minimize the effect of these variables.

Risk-factors for antepartum fetal deaths in the city of São Paulo, Brazil.

OBJECTIVE: To assess risk factors for antepartum fetal deaths. METHODS: A population-based case-control study was carried out in the city of São Paulo from August 2000 to January 2001. Subjects were selected from a birth cohort from a linked birth and death certificate database. Cases were 164 antepartum fetal deaths and controls were drawn from a random sample of 313 births surviving at least 28 days. Information was collected from birth and death certificates, hospital records and home interviews. A hierarchical conceptual framework guided the logistic regression analysis. RESULTS: Statistically significant factors associated with antepartum fetal death were: mother without or recent marital union; mother's education under four years; mothers with previous low birth weight infant; mothers with hypertension, diabetes, bleeding during pregnancy; no or inadequate prenatal care; congenital malformation and intrauterine growth restriction. The highest population attributable fractions were for inadequacy of prenatal care (40%), hypertension (27%), intrauterine growth restriction (30%) and absence of a long-standing union (26%). CONCLUSIONS: Proximal biological risk factors are most important in antepartum fetal deaths. However, distal factors - mother's low education and marital status - are also significant. Improving access to and quality of prenatal care could have a large impact on fetal mortality.

[Quality of life of people living with HIV/AIDS in São Paulo, Brazil]. / Qualidade de vida de pessoas vivendo com HIV/Aids em São Paulo.

OBJECTIVE: To assess quality of life of people living with HIV/AIDS. METHODS: Cross-sectional study conducted in an AIDS outpatient service based on consecutive sampling during the second half of the year 2002. There were selected 365 men and women aged 18 years or older who were attended by the infectious disease physician. Sociodemographic and recent drug use variables and data on clinical conditions were obtained using a questionnaire and quality of life was analyzed using WHOQOL-bref. RESULTS: Scores of the four domains (physical, psychological, social relationships and environment) were very similar. There were statistically significant differences in mean scores for the environment domain according to skin color, with blacks and pardos having lower scores. Women also had the lowest scores for the psychological and environmental domains. Higher income was significantly associated to higher scores in all domains of quality of life, except for the social relationships domain. Subjects with CD4+ cell counts below 200 cells/mm(3) had lower scores for the physical domain. In all domains significantly lower scores were seen for those receiving psychiatric treatment or with an indication for such treatment. CONCLUSIONS: Despite differences in sex, skin color, income, and mental and immunological status, people living with HIV/AIDS have better (physical and psychological) quality of life than other patients but lower quality in social relationships domain. The latter domain could reflect stigmatization and discrimination associated to the difficulties of disclosing their HIV status in social settings and for a safe sex life.

[Disclosure of HIV infection from the perspective of adolescents living with HIV/AIDS and their parents and caregivers]. / A revelação do diagnóstico na perspectiva dos adolescentes vivendo com HIV/AIDS e seus pais e cuidadores.

The purpose of this study was to identify relevant issues in the disclosure of HIV-positive status in children and adolescents, aiming to improve the quality of their healthcare. A qualitative study included adolescents living with HIV/ AIDS and their parents and caregivers at AIDS reference services in São Paulo and Santos, Brazil. In-depth interviews and focus group were used. The main reasons for disclosure were: poor treatment adherence, sexual maturity, adolescent's request, and inadequate procedures by medical staff. Disclosure was a critical moment for adolescents, with a strong impact on their life plans and horizons. Adolescents infected through sexual transmission and drug use reported the most problematic scenes involved in disclosure. Despite its initial negative impact, disclosure resulted in improved healthcare and better dialogue among the adolescents, caregivers, and healthcare providers. The adolescents also requested clear, no-nonsense, honest information. The authors conclude that health services need to actively provide an adequate approach to facilitate disclosure of HIV-positive status to children and adolescents, realizing that it is a long-term process supported by the family and a multidisciplinary team.

[Validation of birth certificates based on data from a case-control study]. / Validade das informações das declarações de nascidos vivos com base em estudo de caso-controle.

The information recorded on birth certificates was validated with data from a perinatal mortality case-control study, obtained from home interviews of mothers and hospital records for cases (early neonatal deaths) and controls. Sensitivity, specificity, and concordance were calculated for all variables and their estimated and real prevalence. The completeness of birth certificates was lowest for mother's parity and presence of congenital anomalies (records without information range from 23% to 31% for cases and controls). Birth certificates correctly identified low birth weight and type of delivery for cases and controls. Birth certificates showed high sensitivity and specificity to detect preterm births within cases. The number of preterm births was underestimated at 30.8% of the controls and 2.9% of the cases. Low maternal education was two times greater on birth certificates than in the mother's interview, for cases and controls. Completeness of birth certificates was higher in controls, but data quality was better in cases.
