ABSTRACT This study describes difficulties in the monitoring of a child born during an oral outbreak of Chagas disease, in which there are several indications that the transmission occurred through the congenital route: 1. the mother was in the third trimester of pregnancy when she was infected; 2. She presented high parasitemia at the time of delivery; 3. In both, the mother and her daughter, T. cruzi was classified as DTU TcIV. The parasites were not found in the blood at birth and the infection was detected only three months later in an asymptomatic infant. As the mother and her child live in a highly endemic area, vector transmission could not be excluded during this period.

OBJECTIVE: To evaluate the impact of a complex-care-based medical school in the context of the Brazilian health care system on students’ career choices. METHODS: This was a retrospective cross-sectional study based on medical regulatory organization records. It included records for 7,419 physicians who graduated from FMUSP. Geographic data were analyzed using Kernel maps, and the statistical analysis was performed with SPSS® version 24.0. A p-value less than 0.05 was considered significant. RESULTS: Of the 7,419 physicians, 68.6% (95% CI 67.5-69.7) were male, and 20.7% (95% CI 19.8%-21.7%) had no medical specialty, compared to 46.4% nationwide. Internal medicine and surgery-based specialties were more popular, accounting for 39.4% (95% CI 38.3%-40.5%) and 16.8% (95% CI 15.5%-17.6%) of our study group, compared to the Brazilian averages of 25.9% and 13.5%. Our graduates also had a higher probability of staying in São Paulo City, especially when born outside the city. CONCLUSION: We believe that FMUSP remains an interesting model for studying the impact of a highly specialized center on the education and career choices of medical students.

Abstract Background The infectious diseases specialist is a medical doctor dedicated to the management of infectious diseases in their individual and collective dimensions. Objectives The aim of this paper was to evaluate the current profile and distribution of infectious diseases specialists in Brazil. Methods This is a cross-sectional study using secondary data obtained from institutions that register medical specialists in Brazil. Variables of interest included gender, age, type of medical school (public or private) the specialist graduated from, time since finishing residency training in infectious diseases, and the interval between M.D. graduation and residency completion. Maps are used to study the geographical distribution of infectious diseases specialists. Results A total of 3229 infectious diseases specialist registries were counted, with 94.3% (3045) of individual counts (heads) represented by primary registries. The mean age was 43.3 years (SD 10.5), and a higher proportion of females was observed (57%; 95% CI 55.3–58.8). Most Brazilian infectious diseases specialists (58.5%) practice in the Southeastern region. However, when distribution rates were calculated, several states exhibited high concentration of infectious diseases specialists, when compared to the national rate (16.06). Interestingly, among specialists working in the Northeastern region, those trained locally had completed their residency programs more recently (8.7 yrs; 95% CI 7.9–9.5) than physicians trained elsewhere in the country (13.6 yrs: 95% CI 11.8–15.5). Conclusion Our study shows that Brazilian infectious diseases specialists are predominantly young and female doctors. Most have concluded a medical residency training program. The absolute majority practice in the Southeastern region. However, some states from the Northern, Northeastern and Southeastern regions exhibit specialist rates above the national average. In these areas, nonetheless, there is a strong concentration of infectious diseases specialists in state capitals and in metropolitan areas.

OBJECTIVE:To characterize the findings of behavioral hearing assessment in HIV-positive individuals who received and did not receive antiretroviral treatment.METHODS:This research was a cross-sectional study. The participants were 45 HIV-positive individuals (18 not exposed and 27 exposed to antiretroviral treatment) and 30 control-group individuals. All subjects completed an audiological evaluation through pure-tone audiometry, speech audiometry, and high-frequency audiometry.RESULTS:The hearing thresholds obtained by pure-tone audiometry were different between groups. The group that had received antiretroviral treatment had higher thresholds for the frequencies ranging from 250 to 3000 Hz compared with the control group and the group not exposed to treatment. In the range of frequencies from 4000 through 8000 Hz, the HIV-positive groups presented with higher thresholds than did the control group. The hearing thresholds determined by high-frequency audiometry were different between groups, with higher thresholds in the HIV-positive groups.CONCLUSION:HIV-positive individuals presented poorer results in pure-tone and high-frequency audiometry, suggesting impairment of the peripheral auditory pathway. Individuals who received antiretroviral treatment presented poorer results on both tests compared with individuals not exposed to antiretroviral treatment.

Compararam-se 24 pacientes coinfectados pelos vírus da hepatite C/vírus linfotrópico de células T humanas do tipo 1 com 6 coinfectados por VHC/HTLV-2 e 55 infectados pelo VHC, no tocante a dados clínico-epidemiológicos, laboratoriais e histopatológicos. A análise discriminante de Fischer foi utilizada para definir funções capazes de diferenciar os grupos de estudo (VHC, VHC/HTLV-1 e VHC/HTLV-2). A acurácia discriminatória foi avaliada pelo por validação cruzada. O uso de álcool, drogas endovenosas, cocaína inalatória e a parceria sexual com UDEV foram mais freqüentes no grupo VHC/HTLV-2, enquanto queixa de dor abdominal e parceiro sexual com hepatite predominaram no grupo VHC. Os coinfectados apresentaram número maior de plaquetas, enquanto as aminotransferases e a gamaglutamiltranspeptidase foram mais altas no grupo VHC. Não houve diferença entre os grupos à análise histopatológica do fígado. Por análise discriminante definiram-se funções classificatórias, incluindo as variáveis sexo, faixa etária, uso de drogas endovenosas e parceiro sexual com hepatite, com acurácia discriminante alta para o grupo VHC.

Twenty-four hepatitis C virus patients coinfected with human T-lymphotropic virus type 1 were compared with six coinfected with HTLV-2 and 55 with HCV alone, regarding clinical, epidemiological, laboratory and histopathological data. Fischer's discriminant analysis was applied to define functions capable of differentiating between the study groups (HCV, HCV/HTLV-1 and HCV/HTLV-2). The discriminant accuracy was evaluated by cross-validation. Alcohol consumption, use of intravenous drugs or inhaled cocaine and sexual partnership with intravenous drug users were more frequent in the HCV/HTLV-2 group, whereas patients in the HCV group more often reported abdominal pain or a sexual partner with hepatitis. Coinfected patients presented higher platelet counts, but aminotransferase and gamma-glutamyl transpeptidase levels were higher among HCV-infected subjects. No significant difference between the groups was seen regarding liver histopathological findings. Through discriminant analysis, classification functions were defined, including sex, age group, intravenous drug use and sexual partner with hepatitis. Cross-validation revealed high discriminant accuracy for the HCV group.

OBJETIVO: Avaliar a associação entre consumo alimentar e presença de obesidade abdominal em indivíduos infectados pelo HIV/Aids, em uso de terapia antiretroviral de alta potência. MÉTODOS: Trata-se de estudo transversal envolvendo 223 indivíduos adultos, realizado no município de São Paulo, em 2002. A população de estudo foi classificada de acordo com a obesidade abdominal, definida pela razão das circunferências da cintura e quadril >0,95 para os homens e >0,85 para mulheres. As variáveis dietéticas estudadas foram consumo de energia (calorias e calorias/quilo de peso corporal), macronutrientes (em gramas e % da energia ingerida), fibra total (gramas) e consumo de frutas, verduras e legumes (gramas). Potenciais fatores de confusão examinados foram sexo, raça, idade, escolaridade, renda, índice de massa corporal, nível de atividade física, tabagismo, contagem de linfócitos T CD4+ e tempo de uso de inibidor de protease. Estimou-se modelo de regressão logística para avaliar a relação entre obesidade abdominal e consumo alimentar. RESULTADOS: A prevalência de obesidade abdominal foi de 45,7% e esteve associada ao maior consumo de lipídeos: para cada aumento de 10 g de lipídio na dieta a chance aumentou 1,28 vezes. O consumo de carboidratos mostrou-se negativamente associado (OR=0,93) com a presença de obesidade abdominal após ajuste pelas variáveis de controle. CONCLUSÕES: Os resultados sugerem que a quantidade de carboidratos e lipídeos na dieta, independente do consumo energético, pode modificar a chance de desenvolver obesidade abdominal na população estudada. Intervenções nutricionais podem ser benéficas na prevenção de obesidade abdominal entre pacientes vivendo com HIV/Aids.

OBJECTIVE: To assess the association between dietary intake and central obesity among people living with HIV/AIDS and receiving highly active antiretroviral therapy. METHODS: A cross-sectional study was conducted involving 223 adult individuals in the city of São Paulo city in 2002. The study population was classified according to central obesity, defined as waist-to-hip ratio >0.95 for men and >0.85 for women. The dietary variables studied were energy consumption (in calories and calories/kilo of body weight), macronutrients (in grams and % of energy intake), total fiber (grams) and fruit and vegetables intake (grams). The potential confounders examined were sex, skin color, age, schooling, income, body mass index, physical activity, smoking habits, peripheral CD4+ T lymphocyte count and length of protease inhibitor use. The multiple logistic regression model was performed in order to evaluate the association between central obesity and dietary intake. RESULTS: The prevalence of central obesity was 45.7% and it was associated with greater consumption of lipids: for every increase of 10g of lipid intake the odds of central obesity increased 1.28 times. Carbohydrate consumption showed negative association (OR=0.93) with central obesity after adjustment for control variables. CONCLUSIONS: The results suggest that the amount of carbohydrates and lipids in the diet, regardless of total energy intake, may modify the chance of developing central obesity in the studied population. Nutritional interventions may be beneficial for preventing central obesity among HIV/AIDS patients.

O objetivo deste estudo foi identificar aspectos da revelação do diagnóstico da infecção pelo HIV a crianças e adolescentes relevantes para a melhoria do cuidado de sua saúde. Trata-se de estudo qualitativo envolvendo entrevistas em profundidade e grupo focal com adolescentes vivendo com HIV/AIDS e seus pais ou cuidadores, em serviços de referência nas cidades de São Paulo e Santos, Brasil. Os resultados apontam como principais razões para a revelação: má adesão ao tratamento, iminência de início da vida sexual, demanda da criança ou adolescente e abordagem inadequada de profissional. A revelação mostrou-se momento crítico, com repercussões sobre projetos e horizontes de vida dos adolescentes. As mais problemáticas foram narradas por adolescentes infectados por via sexual e por uso de drogas. Apesar do impacto negativo inicial, a revelação repercutiu positivamente sobre os cuidados de saúde, com melhoria do diálogo com cuidadores e serviços. Os adolescentes enfatizaram ainda a necessidade de receber informações claras e honestas. Conclui-se pela necessidade de otimizar o processo de revelação, tratando-o como tarefa de longo prazo, negociada ativamente com a família e conduzida por equipes multidisciplinares.

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.

Verificar a validade e reprodutibilidade do questionário Baecke de avaliação da atividade física habitual para portadores do HIV/AIDS. Foram estudadas trinta pessoas na análise da validação. Os escores de atividade física ocupacional (AFO), exercício físico no lazer (EFL), atividades de lazer e locomoção (ALL) e escore total (ET) foram comparados com o consumo de oxigênio de pico, carga de pico e gasto energético. Na análise da reprodutibilidade, foram estudadas 29 pessoas (intervalo entre 15-30 dias). O coeficiente de correlação de Pearson foi utilizado para validação. O coeficiente de correlação intraclasse, teste t-pareado e Bland-Altman foram utilizados para reprodutibilidade. O VO2 pico e a carga de pico foram correlacionados, significativamente com o EFL (r = 0,41; r = 0,43, respectivamente). O gasto energético foi correlacionado, significativamente, com o AFO (r = 0,64). Os coeficientes de correlação intraclasse foram de 0,70 ou superiores para AFO, EFL e ET. Não houve diferenças significativas nas médias dos escores entre as duas medidas, e o método de Bland-Altman mostrou boa concordância para todos os escores. O questionário Baecke mostrou-se válido para avaliação da atividade física habitual em portadores do HIV/AIDS.

This study evaluates the validity and reliability of the Baecke questionnaire on habitual physical activity when applied to a population of HIV/AIDS subjects. Validity was determined by comparing measurements for 30 subjects of peak oxygen uptake, peak workload, and energy expenditure with scores for occupational physical activity (OPA), physical exercise in leisure (PEL), leisure and locomotion activities (LLA), and total score (TS). Reliability was determined by testing and retesting 29 subjects at intervals of 15-30 days. Validity was evaluated with the Pearson correlation and reliability analyses were done using the intraclass correlation, paired Student t-test, and Bland-Altman methods. Peak VO2 and peak workload had significant correlation with PEL (r = 0.41; r = 0.43; respectively). Energy expenditure had a significant correlation with OPA (r = 0.64). The intraclass coefficients were 0.70 or more for OPA, PEL and TS. There was no difference in OPA, PEL, LLA and TS between the two evaluations. The Bland-Altman methods showed that there was good agreement between the measurements for all habitual physical activities scores. Results show that the Baecke questionnaire is valid for the evaluation of habitual physical activity among people living with HIV/AIDS.

OBJETIVO: Validar métodos de estimativas da gordura corporal (somatória de espessura de dobras cutâneas, circunferência da cintura (CC) e razão cintura-quadril (RCQ)) em portadores do HIV/Aids, tendo como padrão ouro a absortometria por dupla emissão de raios-X (Dexa) e a tomografia computadorizada de abdômen (TCA). MÉTODOS: Foram estudados 15 portadores do HIV/Aids tratados em uma unidade de saúde coligada a um hospital público universitário, São Paulo. Foram medidas a gordura subcutânea total (GST) mediante a somatória da espessura de sete dobras (bíceps, tríceps, subescapular, axilar média, supra-ilíaca, abdominal e panturrilha medial), a gordura subcutânea central (GSC) (somatória da espessura de quatro dobras) e a gordura subcutânea de membros (GSM) (somatória da espessura de três dobras). A GST, GSC e GSM foram comparadas com as medidas de gordura obtidas pela Dexa. A CC, a RCQ e a GSC foram comparadas com as medidas de gordura obtidas pela TCA. Na análise estatística, utilizou-se o coeficiente de correlação de Pearson (r) e foi utilizado o teste de Mann-Whitney. RESULTADOS: A gordura medida pela Dexa foi correlacionada com GST, a GSC e GSM, mesmo após o ajuste pela idade (r>0,80 para todos). A gordura total de abdômen medida pela TCA foi correlacionada com a CC, RCQ e a GSC após o ajuste pela idade (r>0,80 para todos). CONCLUSÕES: Os métodos de estimativa da gordura corporal devem ser escolhidos de acordo com o tipo de gordura a ser avaliada e podem ser utilizados em pesquisas e nos serviços de saúde como alternativa à Dexa e TCA para portadores do HIV/Aids.

OBJECTIVE: To validate different methods for estimating HIV/Aids patients' body fat: total body skinfold thickness, central (trunk) skinfold thickness, peripheral (limb) skinfold thickness, waist circumference (WC) and waist-to-hip ratio (WHR). Dual-energy X-ray absorptiometry (DEXA) and computed tomography of the abdomen (CTA) were used as the gold standard. METHODS: An analysis was done on 15 adult HIV/Aids patients (10 men and 5 women) who were being treated at an Aids clinic at a public university hospital, Sao Paulo, Brazil. Their total subcutaneous fat (TSF) was estimated from the sum of the thicknesses of the biceps, triceps, subscapular, midaxillary, suprailiac, abdominal and medial calf skinfolds. The central subcutaneous fat (CSF) was estimated by summing the subscapular, axillary, suprailiac and abdominal skinfold measurements. The peripheral subcutaneous fat (PSF) was estimated by summing the biceps, triceps and medial calf skinfold measurements. These were compared with Dexa. The WC, WHR and CSF were compared with CTA. In the statistical analysis, the Pearson correlation coefficient (r) and Mann-Whitney test were utilized. RESULTS: There was a correlation between fat mass measured by DEXA and by TSF, CSF and PSF, even after adjusting for age (r>0.80 for all). WC, WHR and CSF presented correlation with total abdominal fat measured by CTA, even after adjusting for age (r>0.80 for all). CONCLUSIONS: The methods for estimating body fat should be chosen according to the type of fat to be evaluated and can be used in research and healthcare services instead of DEXA and CTA for HIV/AIDS patients.

OBJETIVO: Avaliar o estado nutricional de indivíduos portadores do HIV/AIDS em uso de terapia anti-retroviral de alta potência, segundo sexo e número de linfócitos T CD4.+. MATERIAL E MÉTODOS: Estudo transversal envolvendo 223 indivíduos (171 homens e 52 mulheres) tratados com inibidores de protease, com idade entre 20 e 59 anos, recrutados em um serviço de referência em tratamento de HIV/AIDS do município de São Paulo. Os dados antropométricos utilizados foram peso, estatura e circunferência da cintura (CC). O índice de massa corporal (IMC) foi calculado como a razão entre peso (kg) e estatura ao quadrado (m²), de acordo com o critério de classificação proposto pela Organização Mundial de Saúde. Os pacientes foram divididos em três categorias por número de linfócitos T CD4.+: < 200, 201 - 349 e > 350 (cel/mm³). RESULTADOS: A prevalência de sobrepeso na população foi de 30,5%, e de obesidade abdominal de 12,6%. As mulheres apresentaram prevalência maior de sobrepeso (36,5%) e de obesidade abdominal (32,7%) quando comparadas aos homens (28,7% e 6,4% respectivamente). A prevalência de baixo peso foi maior nas mulheres (7,7%) do que nos homens (2,3%). Ausência de associação significativa entre sobrepeso, obesidade abdominal e número de linfócitos T CD4.+ foi observada tanto nos homens como nas mulheres. CONCLUSÃO: As mulheres apresentaram prevalências maiores de baixo peso, sobrepeso e obesidade abdominal em relação aos homens. A obesidade é o desvio do estado nutricional mais importante, superando a desnutrição, nesta população de indivíduos portadores do HIV/AIDS em uso de terapia anti-retroviral de alta potência.

OBJECTIVE: To evaluate the nutritional status of HIV/AIDS patients treated with highly active antiretroviral therapy, according to gender and T CD4 + lymphocyte count. MATERIAL AND METHODS: This was a cross-sectional study, including 223 individuals (171 men and 52 women) treated with protease inhibitors, aged between 20 and 59 years. This study was developed at a HIV/AIDS reference treatment center in the city of São Paulo. Anthropometric data, including current weight, height, and waist circumference (WC) were collected. The body mass index (BMI) was calculated as the ratio between weight (kg) and the square of the height (m²), according to World Health Organization classification criteria. Patients were divided into three groups according to T CD4+ lymphocyte count: < 200, 201-349, and > 350 (cel/mm³). RESULTS: The prevalence of overweight was 30.5% and of central obesity was 12.6%. Women presented a higher prevalence of overweight (36.5%) and of central obesity (32.7%) when compared to men (28.7% and 6.4% respectively). The prevalence of underweight was higher among women than in men, respectively 7.7% and 2.3%. Categories of T CD4 + lymphocyte counts were not associated with overweight and central obesity in this population. CONCLUSION: Women presented a higher prevalence of underweight, overweight and central obesity in relation to men. Obesity is the most important deviation of nutritional status, overcoming malnutrition, in these HIV/AIDS patients treated with highly active antiretroviral therapy.
