Fatores associados ao controle glicêmico em pessoas com diabetes na Estratégia Saúde da FamÃlia em Pernambuco
OBJETIVO Identificar los factores asociados con el control glucémico en personas con Diabetes Mellitus (DM) tipo 2 registradas en la Estrategia Salud de la Familia (ESF) en Pernambuco, Brasil. MÉTODO Fueron investigadas, por regresión múltiple, las asociaciones entre el control glucémico (hemoglobina A glicosilada menor o mayor o igual al 7%) presentado por las personas con DM y variables relacionadas con condiciones sociodemográficas, hábitos de vida, caracterÃsticas de la diabetes, de su tratamiento y seguimiento de los pacientes por los servicios sanitarios. RESULTADOS Más del 65% de los participantes presentaron control glucémico inadecuado, especialmente aquellos de menos edad, duración de la enfermedad más larga, más contactos anuales con la ESF y régimen terapéutico complejo. Personas con DM sin derivaciones a especialistas presentaron un mayor descontrol glucémico. Asociaciones con escolaridad y obesidad no permanecieron significativas en el modelo multivariado. CONCLUSIÓN La evolución de la diabetes dificulta el control adecuado. Sin embargo, la atención a las personas con DM más jóvenes y las derivaciones a especialistas son factores susceptibles de mejora del control glucémico.OBJETIVO Identificar fatores associados ao controle glicêmico em pessoas com Diabetes Mellitus (DM) tipo 2 cadastradas na Estratégia Saúde da FamÃlia (ESF) em Pernambuco, Brasil. MÉTODO Foram investigadas, por regressão múltipla, as associações entre o controle glicêmico (hemoglobina A glicosilada menor ou maior ou igual a 7%) apresentado pelas pessoas com DM e variáveis relacionadas com condições sociodemográficas, hábitos de vida, caracterÃsticas do diabetes, de seu tratamento e acompanhamento dos pacientes pelos serviços de saúde.

Pessoas com DM sem encaminhamentos para especialistas apresentaram um maior descontrole glicêmico. Associações com escolaridade e obesidade não permaneceram significativas no modelo multivariado. CONCLUSÃO A evolução do diabetes dificulta o controle adequado, todavia, a atenção à s pessoas com DM mais jovens e os encaminhamentos para especialistas são fatores suscetÃveis de melhora do controle glicêmico.OBJECTIVE Identifying factors associated with glycemic control in people with type 2 Diabetes Mellitus (DM) registered in the Family Health Strategy (FHS) in Pernambuco, Brazil. METHOD Associations between glycemic control (glycosylated hemoglobin A lower or equal to 7%) presented by people with DM and variables related to sociodemographic conditions, lifestyle, characteristics of diabetes, treatment and follow-up of patients by health services were investigated by multiple regression. RESULTS More than 65% of the participants presented inadequate glycemic control, especially those with lower age, longer illness duration, more annual contacts with FHS and complex therapeutic regimen. People with DM without referrals to specialists presented greater glycemic control. Associations with education level and obesity did not remain significant in the multivariate model. CONCLUSION The evolution of diabetes hinders adequate control, however, attention to younger people with DM and referrals to specialists are factors that can improve glycemic control
Incidence and risk factors for tuberculosis in people living with HIV: cohort from HIV referral health centers in Recife, Brazil.
OBJECTIVE: To identify the incidence of and risk factors for tuberculosis in people living with HIV (PLHIV). DESIGN: Observational, prospective cohort study. METHODS: A total of 2069 HIV-infected patients was observed between July 2007 and December 2010. The Kaplan-Meier method was used to estimate the probability of survival free of tuberculosis, and Cox regression analysis to identify risk factors associated with the development of tuberculosis. RESULTS: Survival free of tuberculosis (TB) was 91%. The incidence rate of tuberculosis was 2.8 per 100 persons/years. Incidence of tuberculosis was higher when subjects had CD4 cell count <200 cells/mm(3); were not on antiretroviral therapy; in those who had, a body mass index <18.5 kg/m(2), anemia (or were not tested for it), were illiterate or referred previous tuberculosis treatment at entry into the cohort. Those not treated for latent TB infection had a much higher risk (HR = 7.9) of tuberculosis than those with a negative tuberculin skin test (TST). Having a TST≥5 mm but not being treated for latent TB infection increased the risk of incident tuberculosis even in those with a history of previous tuberculosis. CONCLUSIONS: Preventive actions to reduce the risk of TB in people living with HIV should include an appropriate HAART and treatment for latent TB infection in those with TST≥5 mm. The actions towards enabling rigorous implementation of treatment of latent TB infection and targeting of PLHIV drug users both at the individual and in public health level can reduce substantially the incidence of TB in PLHIV
Survival and mortality profile among people living with HIV in a cohort in the Northeastern region of Brazil
Conditions related to the acquired immune deficiency syndrome (AIDS) are still a significant cause of morbidity and mortality among people living with HIV (PLHIV). Longer survival in this population were reported to increase the risk of developing noncommunicable chronic diseases (NCDs). This study aimed to estimate the survival and causes of death according to age group and sex among PLHIV monitored at two referral centers in the Northeastern Brazil. This is a prospective, retrospective cohort with death records from 2007 to 2018, based on a database that registers causes of death using the International Classification of Disease (ICD-10), which were subsequently coded following the Coding Causes of Death in HIV (CoDe). A total of 2,359 PLHIV participated in the study, with 63.2% being men, with a follow-up period of 13.9 years. Annual mortality rate was 1.46 deaths per 100 PLHIV (95% CI: 1.33 – 1.60) with a frequency of 20.9%. Risk of death for men increased by 49% when compared to women, and the risk of death in PLHIV increased by 51% among those aged 50 years and over at the time of diagnosis. It was observed that 73.5% accounted for AIDS-related deaths, 6.9% for non-AIDS defining cancer, 6.3% for external causes, and 3.2% for cardiovascular diseases. Among the youngest, 97.2% presented an AIDS-related cause of death. Highest frequency of deaths from neoplasms was among women and from external causes among men. There is a need for health services to implement strategies ensuring greater adherence to treatment, especially among men and young people. Moreover, screening for chronic diseases and cancer is essential, including the establishment of easily accessible multidisciplinary care centers that can identify and address habits such as illicit drug use and alcoholism, which are associated with violent deaths
Validating a scoring system for the diagnosis of smear-negative pulmonary tuberculosis in HIV-infected adults.
BACKGROUND: The challenge of diagnosing smear-negative pulmonary TB (tuberculosis) in people living with HIV justifies the use of instruments other than the smear test for diagnosing the disease. Considering the clinical-radiological similarities of TB amongst HIV-infected adults and children, the proposal of this study was to assess the accuracy of a scoring system used to diagnose smear-negative pulmonary TB in children and adolescents, in HIV-infected adults suspected of having smear-negative pulmonary TB. METHODS: A Phase III validation study aiming to assess the diagnostic accuracy of a scoring system for diagnosing smear-negative pulmonary TB in HIV-infected adults. The study assessed sensitivity, specificity, positive and negative likelihood ratios, and positive and negative predictive values of the scoring system. Three versions of the scoring system were tested. RESULTS: From a cohort of 2,382 (HIV-infected adults), 1276 were investigated and 128 were diagnosed with pulmonary TB. Variables associated with the diagnosis of TB were: coughing, weight loss, fever, malnutrition, chest X-ray, and positive tuberculin test. The best diagnostic performance occurred with the scoring system with new scores, with sensitivity = 81.2% (95%-CI 74.5% -88%), specificity = 78% (75.6% -80.4%), PPV = 29.2% (24.5% -33.9%) and NPV = 97.4% (96.4% -98.4%), LR+ = 3.7 (3.4-4.0) and LR- = 0.24 (0.2-0.4). CONCLUSION: The proposed scoring system (with new scores) presented a good capacity for discriminating patients who did not have pulmonary TB, in the studied population. Further studies are necessary in order to validate it, thus permitting the assessment of its use in diagnosing smear-negative pulmonary TB in HIV-infected adults
The frequency and clinical presentation of Zika virus coinfections: a systematic review.
BACKGROUND: There is limited knowledge on the influence of concurrent coinfections on the clinical presentation of Zika virus (ZIKV) disease. METHODS: To better understand the types, frequencies and clinical manifestations of ZIKV coinfections, we did a systematic review of four databases (PubMed, Embase, Web of Science, LILACS) without restrictions for studies on ZIKV coinfections confirmed by nucleic acid (quantitative real-time-PCR) testing of ZIKV and coinfecting pathogens. The review aimed to identify cohort, cross-sectional, case series and case report studies that described frequencies and/or clinical signs and symptoms of ZIKV coinfections. Conference abstracts, reviews, commentaries and studies with imprecise pathogen diagnoses and/or no clinical evaluations were excluded. RESULTS: The search identified 34 articles from 10 countries, comprising 2 cohort, 10 cross-sectional, 8 case series and 14 case report studies. Coinfections were most frequently reported to have occurred with other arthropod-borne viruses (arboviruses); out of the 213 coinfections described, ZIKV infections co-occurred with chikungunya in 115 cases, with dengue in 68 cases and with both viruses in 19 cases. Other coinfecting agents included human immunodeficiency, Epstein-Barr, human herpes and Mayaro viruses, Leptospira spp, Toxoplasma gondii and Schistosoma mansoni. ZIKV-coinfected cases primarily presented with mild clinical features, typical of ZIKV monoinfection; however, 9% of cases in cohort and cross-sectional studies were reported to experience complications. CONCLUSION: Based on the evidence collated in this review, coinfections do not appear to strongly influence the clinical manifestations of uncomplicated ZIKV infections. Further research is needed to confirm whether risk of severe complications is altered when ZIKV infection co-occurs with other infections. PROSPERO REGISTRATION NUMBER: CRD42018111023
Non Electrocardiographic alterations in exercise testing in asymptomatic women. Associations with cardiovascular risk factors
OBJECTIVES: To estimate the prevalence of exercise testing alterations in middle-aged women without symptoms of heart disease and to verify the associations of functional capacity and heart rate behavior during and after exercise with cardiovascular risk factors. METHODS: A cross-sectional study was conducted with 509 asymptomatic women aged between 46 and 65 years who underwent clinical evaluations and exercise testing (Bruce protocol). The heart rate behavior was evaluated by the maximal predicted heart rate achieved, chronotropic index and recovery heart rate. RESULTS: The mean age was 56.4±4.8 years, and 13.4% of the patients had a Framingham risk score above 10%. In the exercise treadmill testing, 58.0% presented one or more of the following alterations (listed in order of ascending prevalence): symptoms (angina, dyspnea, and dizziness), ST-segment depression, arrhythmia, reduction in recovery heart rate of p12 bpm at 1 minute, altered maximal predicted heart rate achieved, abnormal blood pressure, functional capacity deficiency, and altered chronotropic index. In the multivariate analysis, the following associations (odds ratio) were observed for these alterations: chronotropic index was associated with obesity (2.08) and smoking (4.47); maximal predicted heart rate achieved was associated with smoking (6.45); reduction in the recovery heart rate at 1 minute was associated with age (1.09) and obesity (2.78); functional capacity was associated with age (0.92), an overweight status (2.29) and obesity (6.51). CONCLUSIONS: More than half of middle-aged women without cardiovascular symptoms present alterations in one or more exercise testing parameters. Alterations in the functional capacity or heart rate behavior, as verified by exercise testing, are associated with age, smoking, an overweight status and obesity
Comparison between potential risk factors for cardiovascular disease in people living with HIV/AIDS in areas of Brazil
Introduction: Coronary heart disease and its risk factors depend on genetic characteristics, behaviors, and habits, all of which vary in different regions. The use of antiretroviral therapy (ARV) has increased the survival of people living with HIV/AIDS (PLWHA), who begin to present mortality indicators similar to the general population. This study aimed to compare the prevalence of factors potentially associated with coronary heart disease in three cohorts of PLWHA from three different regions of Brazil. Methodology: The study population was composed of participants of the cohorts of Pernambuco, Goiás, and Rio Grande do Sul states. In these sites, adult patients attending reference centers for treatment of HIV/AIDS were consecutively enrolled. Results: Pernambuco and Goiás had a higher proportion of males and of individuals with high-risk high-density lipoprotein (HDL). Pernambuco also had a greater proportion of individuals with hypertension, elevated triglycerides, and CD4 counts below 200 cells/mm3. Lower education was more frequent in Rio Grande do Sul, and the use of cocaine was higher in this state. Conclusions: The results confirm the importance of risk factors for coronary heart disease in PLHIV and highlight differences in the three cohorts. Specific measures against smoking and sedentary lifestyle, avoidance of advanced stages of immunosuppression, and appropriate treatment of dyslipidemia and dysglicemia are urgently needed to cope with the disease in Brazil
Early epilepsy in children with Zika-related microcephaly in a cohort in Recife, Brazil: Characteristics, electroencephalographic findings, and treatment response.
OBJECTIVE: To estimate the incidence of epilepsy in children with Zika-related microcephaly in the first 24 months of life; to characterize the associated clinical and electrographic findings; and to summarize the treatment responses. METHODS: We followed a cohort of children, born during the 2015-2016 Zika virus (ZIKV) epidemic in Brazil, with congenital microcephaly and evidence of congenital ZIKV infection on neuroimaging and/or laboratory testing. Neurological assessments were performed at ≤3, 6, 12, 15, 18, 21, and 24 months of life. Serial electroencephalograms were performed over the first 24 months. RESULTS: We evaluated 91 children, of whom 48 were female. In this study sample, the cumulative incidence of epilepsy was 71.4% in the first 24 months, and the main type of seizure was infantile spasms (83.1%). The highest incidence of seizures occurred between 3 and 9 months of age, and the risk remained high until 15 months of age. The incidence of infantile spasms peaked between 4 and 7 months and was followed by an increased incidence of focal epilepsy cases after 12 months of age. Neuroimaging results were available for all children, and 100% were abnormal. Cortical abnormalities were identified in 78.4% of the 74 children evaluated by computed tomography and 100% of the 53 children evaluated by magnetic resonance imaging. Overall, only 46.1% of the 65 children with epilepsy responded to treatment. The most commonly used medication was sodium valproate with or without benzodiazepines, levetiracetam, phenobarbital, and vigabatrin. SIGNIFICANCE: Zika-related microcephaly was associated with high risk of early epilepsy. Seizures typically began after the third month of life, usually as infantile spasms, with atypical electroencephalographic abnormalities. The seizure control rate was low. The onset of seizures in the second year was less frequent and, when it occurred, presented as focal epilepsy
Metodologia de um estudo de inquérito nacional da prevalência e de padrõesa epidemiológicos das hepatites A, B e C no Brasil
Um inquérito de base populacional foi conduzido na população urbana de todas as capitais e do Distrito Federal no Brasil para fornecer informações sobre a prevalência de hepatites virais e fatores de risco, entre 2005 e 2009. Este artigo descreve o delineamento e a metodologia do estudo que envolveu a população com idade entre 5 e 19 anos para hepatite A e 10 a 69 anos para hepatite B e C. As entrevistas e amostras de sangue foram obtidas através de visitas domiciliares e a amostra selecionada a partir de uma amostragem estratificada em múltiplos estágios (por conglomerado) com igual probabilidade para cada domÃnio de estudo (região e faixa etária). Nacionalmente, 19.280 residências e ~31.000 indivÃduos foram selecionados. O tamanho da amostra foi suficiente para detectar uma prevalência em torno de 0,1% e para avaliar os fatores de risco por região. A metodologia apresentou-se viável para distinguir entre diferentes padrões epidemiológicos da hepatite A, B e C. Estes dados serão de valia para a avaliação das polÃticas de vacinação e para o desenho de estratégias de controle.A population-based survey to provide information on the prevalence of hepatitis viral infection and the pattern of risk factors was carried out in the urban population of all Brazilian state capitals and the Federal District, between 2005 and 2009. This paper describes the design and methodology of the study which involved a population aged 5 to 19 for hepatitis A and 10 to 69 for hepatitis B and C. Interviews and blood samples were obtained through household visits. The sample was selected using stratified multi-stage cluster sampling and was drawn with equal probability from each domain of study (region and age-group). Nationwide, 19,280 households and ~31,000 residents were selected. The study is large enough to detect prevalence of viral infection around 0.1% and risk factor assessments within each region. The methodology seems to be a viable way of differentiating between distinct epidemiological patterns of hepatitis A, B and C. These data will be of value for the evaluation of vaccination policies and for the design of control program strategies
