Estudo epidemiológico de agentes virais (HIV, HTLV, VHB e CMV) identificados em adolescentes grávidas atendidas em um centro de referência do Sistema Único de Saúde de Belém, Pará

A prevalência da infecção por agentes virais como o HIV-1, HTLV1/2, VHB e CMV, ainda é pouco conhecida na população de adolescentes grávidas na região norte do Brasil. Este trabalho teve como um dos objetivos descrever esta prevalência das infecções HIV-1, HTLV1/2, VHB e CMV em adolescentes grávidas atendidas em um centro de referência do estado do Pará. Foram coletadas amostras de sangue de 324 gestantes procedentes de vários municípios do estado no período de novembro de 2009 a fevereiro de 2010. As amostras foram submetidas a um ensaio imunoenzimático do tipo ELISA, para a detecção de anticorpos anti-HIV, anti HTLV-1/2, anti-VHB e anti-CMV IgM/IgG. A análise sorológica revelou uma amostra soropositiva para o HIV-1, duas amostras positivas para HTLV1/2, enquanto a maioria das amostras apresentaram anticorpos anti-CMV IgG, embora a ocorrência da infecção aguda tenha sido baixa (2,2%). A prevalência da infecção para VHB em adolescentes gestantes foi de 0,62%, porém numero expressivo (83,3%) de adolescentes estão suscetíveis a infecção pelo VHB, o que sugere que não foram imunizadas. A maioria (63,4%) das adolescentes continuaram estudando mesmo sabendo da gravidez e 34,6% buscaram o pré-natal tardiamente possibilitando um numero mínimo de quatro consultas de pre natal O resultado reforça a hipótese que estas adolescentes grávidas possuem uma prevalência de infecções desses tipos virais, semelhante a taxas nacionais das gestantes de modo geral. A prevalência dos subtipos virais (HTLV-2 e HIV-1 subtipo B) obtidas através da caracterização molecular das amostras soropositivas das gestantes foi concordante com a prevalência dos subtipos da região norte.

(In)visíveis sequelas: a violência psicológica contra a mulher sob o enfoque gestáltico

A modalidade violência psicológica é mais conhecida pela sua “invisibilidade” no âmbito público em razão de, entre outros fatores, ocorrer mais frequentemente na esfera privada, bem como por não deixar marcas físicas. Atualmente, a Lei 11.340/2006, batizada de “Lei Maria da Penha”, depois de sancionada, traduz uma forma de amparo legal e institucionalizado para as mulheres. Empregamos a concepção de gênero segundo Scott (1991), como uma das ferramentas analíticas que permitem identificar nexos entre a construção socioeconômica da violência e as políticas do Estado. Neste panorama, apresentamos como objetivo geral desta pesquisa empírica desvelar algumas (in) visíveis sequelas psíquicas e sociais e de modo específico as repercussões na subjetividade da mulher que vivencia situações de violência psicológica ocorridas em âmbito doméstico e intrafamiliar. As análises foram realizadas na perspectiva Gestáltica, uma abordagem psicológica do contato consciente, cuja intervenção permite o fortalecimento do suporte interno e auto-regulação saudável, de modo a superar situações que obscurecem as funções e fronteiras de contato. Trata-se de uma pesquisa clínico-qualitativa de base fenomenológico-existencial-gestáltica e hermenêutica. Os procedimentos utilizados foram: submissão do projeto ao Comitê de Ética do CCS/UFPA; obtenção da autorização Institucional; identificação e convite a três mulheres para participarem da pesquisa, segundo o perfil de inclusão na amostra: disponibilidade para a pesquisa, faixa etária de 25 a 45 anos, que esteve ou está vivenciando situação de violência psicológica com seu marido/companheiro. Posteriormente, foi assinado o Termo de Consentimento Livre e Esclarecido e realizado as entrevistas semi-dirigidas através de perguntas abertas (gravadas em áudio). As mesmas foram transcritas e analisadas. O local da pesquisa foi o Centro de Referência Maria do Pará. Utilizamos para a análise dos discursos coletados a compreensão de Ricouer (1975) e os conceitos Gestálticos de contato, funções e fronteiras de contato, mecanismos de defesa, self, ajustamento criativo e awareness. O resultado aponta para o desvelamento de vividos permeados de agressões verbais em forma de humilhações, xingamentos, ofensas, ciúmes, desqualificação de sua aparência física, falta de diálogo, isolamento social e emocional, medo, sofrimento, dor, angústia, culpa, vergonha, sentimentos de ódio, raiva, tristeza e impotência diante de tal violência. Concluímos que a “invisibilidade” de tais experiências de violência psicológica gera visíveis interrupções no contato consigo mesma, em suas relações familiares e sociais, bem como, imprime profundas e danosas desestruturações na personalidade e na maneira da mulher expressar sua subjetividade.

Sistema atende mulher: sistema de informação no centro de referência da mulher Ednalva Bezerra

The physical, psychological, sexual, moral and patrimonial violence affects women of different ages, social classes, ethnic and racial groups, levels of education and religion, all over Brazil. One of the obstacles in the strategies of prevention and facing violence against women, in public care services, focuses on the absence of an information system, automation of data and care flows. The existence of reliable data is essential for performing diagnoses, goals and conducting research on women in situations of violence who access the service agencies. In this sense, the goal of research is to present the experience of implementing a policy of data management called Woman System, in Ednalva Bezerra Women's Reference Center, which offers host/psychological and social care, guidance and legal referral for women that face any violence situation. As methodological paths, we adopt research in action. In our analyzes, we found that in this kind of public service, the use of the data system may improve the full and humanized care to women in situations of violence. Thus, the System Woman Care, still a developing phase, appears to improve the flow of relevant information within the institution, driving a process of knowledge, decision-making and intervention against gender violence.

Percepção de pacientes HIV-positivos de um centro de referência em relação a tratamento de saúde

Introduction: health professionals, in many cases, have defensive and exclusionary practices, patterns of prejudice and discrimination in response to HIVpositive patients. Objective: to verify the perception of patients seropositives from a reference center for STD/HIV/aids in relation to health care. Methods: there were interviews with questions related to discriminatory attitudes suffered, access and health care. Results: 130 individuals participated in the survey, from which 30 (23.1%) reported events of discrimination suffered outside the center of reference, predominantly from surgeon-dentists and 112 (86.2%) believed to have the same access and health care as other citizens. 62 (47.7%) treated with the dental center of reference, of which 56 (90.3%) felt good being treated in a dental unit only for HIV positive and six (9.7%) were indifferent, believed to be more exposed, or have a bias to attend dental seropositive individuals. Conclusion: it is concluded that many patients have already been discriminated against outside the reference center. However, most of them have a positive feeling towards the treatment received at a specifi c place for treating HIV-positive patients, due to the feeling of being welcome at that place due to the humanization and access to health care.

Dental care for cerebral palsy patients using auxiliary resources to inhibit pathological tonic reflexes

Cerebral paralysis is a chronic illness that affects the central nervous system. In this article the author describes the techniques used at CAOE (Odontological Center for Assistance to patients with special needs) to restraint CP patients during dental treatment, because they present some pathological reflexes which interfere in their odontological assistance. Also it shows how to perform a special physical restraint and how to keep the mouth open by using simple tools including a homemade one. All the devices used during the dental treatment in cerebral palsy patients, such as the physical restraint with bands or sheet to wrap them up, cylindrical pad or cushion made of a soft material, or simple tools including a homemade one to keep the mouth open are usually and safely used in CAOE. All these simple devices are necessary, because there are no available funds for the acquisition of expensive material or equipment. Despite of a shortage of resources we can easily and efficiently assist these patients.

Gram-negative osteomyelitis: clinical and microbiological profile

Introduction: Despite the growing interest in the study of Gram-negative bacilli (GNB) infections, very little information on osteomyelitis caused by GNB is available in the medical literature. Objectives and methods: To assess clinical and microbiological features of 101 cases of osteomyelitis caused by GNB alone, between January 2007 and January 2009, in a reference center for the treatment of high complexity traumas in the city of Sao Paulo. Results: Most patients were men (63%), with median age of 42 years, affected by chronic osteomyelitis (43%) or acute osteomyelitis associated to open fractures (32%), the majority on the lower limbs (71%). The patients were treated with antibiotics as inpatients for 40 days (median) and for 99 days (median) in outpatient settings. After 6 months follow-up, the clinical remission rate was around 60%, relapse 19%, amputation 7%, and death 5%. Nine percent of cases were lost to follow-up. A total of 121 GNB was isolated from 101 clinical samples. The most frequently isolated pathogens were Enterobacter sp. (25%), Acinetobacter baumannii (21%) e Pseudomonas aeruginosa (20%). Susceptibility to carbapenems was about 100% for Enterobacter sp., 75% for Pseudomonas aeruginosa and 60% for Acinetobacter baumannii. Conclusion: Osteomyelitis caused by GNB remains a serious therapeutic challenge, especially when associated to nonfermenting bacteria. We emphasize the need to consider these agents in diagnosed cases of osteomyelitis, so that an ideal antimicrobial treatment can be administered since the very beginning of the therapy.

Measuring Adherence to Antiretroviral Treatment: The Role of Pharmacy Records of Drug Withdrawals

This study aimed to evaluate adherence to anti-retroviral treatment (ART) among HIV + adults, assess its association with HIV viral load (VL) and identify factors associated to adherence. A survey involving a random sample of adults followed at a HIV/AIDS reference center in Sao Paulo city, Brazil, from 2007 to 2009 was done. A questionnaire was applied and data were retrieved from the pharmacy and medical records. The study involved 292 subjects: 70.2% men; median age: 43 years; median duration of ART: 8 years. 89.3% self-reported taken all prescribed pills in the last 3 days but only 39.3% picked up >= 95% of the prescribed ART from the pharmacy in the last 12 months. At the multivariate analysis having symptoms prior to ART, taking fewer ART pills, and not missing medical appointments were independently associated to higher adherence. Adherence was strongly associated with undetectable HIV VL. Rates of undetectable HIV VL did not differ from 80 to >= 95% of adherence.

The Role of Target Therapies in Schistosomiasis-Associated Pulmonary Arterial Hypertension

Background: Schistosomiasis-associated pulmonary arterial hypertension (Sch-PAH) may be one of the most prevalent forms of pulmonary arterial hypertension (PAH) worldwide. However, the clinical and hemodynamical response to specific PAH therapy in Sch-PAH is not known. Methods: We retrospectively analyzed the charts of all patients with Sch-PAH who initiated specific PAH treatment between June 2003 and June 2010 in a single PAH reference center in Sao Paulo, Brazil. Clinical and hemodynamical data were retrospectively collected and evaluated in two periods: baseline and posttreatment. Results: The study population consisted of 12 patients with Sch-PAH. They were treated with phosphodiseterase-5 inhibitors (seven patients), endothelin receptor antagonists (four patients), or combination therapy (one patient). Mean treatment period was 34.9 +/- 15.5 months. Patients with Sch-PAH presented significant improvements in terms of functional class, 6-min walk test distance (439 +/- 85 to 492 +/- 79 m, P = .032), cardiac index (2.66 +/- 0.59 to 3.08 +/- 0.68 L/min/m(2), P = .028), and indexed pulmonary vascular resistance (20.7 +/- 11.6 to 15.9 +/- 9 W/m(2), P = .038) with the introduction of specific PAH treatment. Conclusions: We conclude that specific PAH therapy may be of benefit to patients with Sch-PAH, considering clinical, functional, and hemodynamic parameters. CHEST 2012; 141(4):923-928

Prediction of tolerance in children with IgE mediated cow's milk allergy by microarray profiling and chemometric approach

The sera of a retrospective cohort (n = 41) composed of children with well characterized cow's milk allergy collected from multiple visits were analyzed using a protein microarray system measuring four classes of immunoglobulins. The frequency of the visits, age and gender distribution reflected real situation faced by the clinicians at a pediatric reference center for food allergy in 530 Paulo, Brazil. The profiling array results have shown that total IgG and IgA share similar specificity whilst IgM and in particular IgE are distantly related. The correlation of specificity of IgE and IgA is variable amongst the patients and this relationship cannot be used to predict atopy or the onset of tolerance to milk. The array profiling technique has corroborated the clinical selection criteria for this cohort albeit it clearly suggested that 4 out of the 41 patients might have allergies other than milk origin. There was also a good correlation between the array data and ImmunoCAP results, casein in particular. By using qualitative and quantitative multivariate analysis routines it was possible to produce validated statistical models to predict with reasonable accuracy the onset of tolerance to milk proteins. If expanded to larger study groups, the array profiling in combination with the multivariate techniques show potential to improve the prognostic of milk allergic patients. (C) 2012 Elsevier B.V.

Healthcare-associated infection in hematopoietic stem cell transplantation patients: risk factors and impact on outcome

Objective: The objective of this study was to analyze the incidence of and risk factors for healthcare-associated infections (HAI) among hematopoietic stem cell transplantation (HSCT) patients, and the impact of such infections on mortality during hospitalization. Methods: We conducted a 9-year (2001-2009) retrospective cohort study including patients submitted to HSCT at a reference center in Sao Paulo, Brazil. The incidence of HAI was calculated using days of neutropenia as the denominator. Data were analyzed using EpiInfo 3.5.1. Results: Over the 9-year period there were 429 neutropenic HSCT patients, with a total of 6816 days of neutropenia. Bloodstream infections (BSI) were the most frequent infection, presenting in 80 (18.6%) patients, with an incidence of 11.7 per 1000 days of neutropenia. Most bacteremia was due to Gram-negative bacteria: 43 (53.8%) cases were caused by Gram-negative species, while 33 (41.2%) were caused by Gram-positive species, and four (5%) by fungal species. Independent risk factors associated with HAI were prolonged neutropenia (odds ratio (OR) 1.07, 95% confidence interval (CI) 1.04-1.10) and duration of fever (OR 1.20, 95% CI 1.12-1.30). Risk factors associated with death in multivariate analyses were age (OR 1.02, 95% CI 1.01-1.43), being submitted to an allogeneic transplant (OR 3.08, 95% CI 1.68-5.56), a microbiologically documented infection (OR 2.96, 95% CI 1.87-4.6), invasive aspergillosis disease (OR 2.21, 95% CI 1.1-4.3), and acute leukemias (OR 2.24, 95% CI 1.3-3.6). Conclusions: BSI was the most frequent HAI, and there was a predominance of Gram-negative microorganisms. Independent risk factors associated with HAI were duration of neutropenia and fever, and the risk factors for a poor outcome were older age, type of transplant (allogeneic), the presence of a microbiologically documented infection, invasive aspergillosis, and acute leukemia. Further prospective studies with larger numbers of patients may confirm the role of these risk factors for a poor clinical outcome and death in this transplant population.

Is waist-to-height ratio a useful indicator of cardio-metabolic risk in 6-10-year-old children?

Background: Childhood obesity is a public health problem worldwide. Visceral obesity, particularly associated with cardio-metabolic risk, has been assessed by body mass index (BMI) and waist circumference, but both methods use sex-and age-specific percentile tables and are influenced by sexual maturity. Waist-to-height ratio (WHtR) is easier to obtain, does not involve tables and can be used to diagnose visceral obesity, even in normal-weight individuals. This study aims to compare the WHtR to the 2007 World Health Organization (WHO) reference for BMI in screening for the presence of cardio-metabolic and inflammatory risk factors in 6–10-year-old children. Methods: A cross-sectional study was undertaken with 175 subjects selected from the Reference Center for the Treatment of Children and Adolescents in Campos, Rio de Janeiro, Brazil. The subjects were classified according to the 2007 WHO standard as normal-weight (BMI z score > −1 and < 1) or overweight/obese (BMI z score ≥ 1). Systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glycemia, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride (TG), Homeostatic Model Assessment – Insulin Resistance (HOMA-IR), leukocyte count and ultrasensitive C-reactive protein (CRP) were also analyzed. Results: There were significant correlations between WHtR and BMI z score (r = 0.88, p < 0.0001), SBP (r = 0.51, p < 0.0001), DBP (r = 0.49, p < 0.0001), LDL (r = 0.25, p < 0.0008, HDL (r = −0.28, p < 0.0002), TG (r = 0.26, p < 0.0006), HOMA-IR (r = 0.83, p < 0.0001) and CRP (r = 0.51, p < 0.0001). WHtR and BMI areas under the curve were similar for all the cardio-metabolic parameters. A WHtR cut-off value of > 0.47 was sensitive for screening insulin resistance and any one of the cardio-metabolic parameters. Conclusions: The WHtR was as sensitive as the 2007 WHO BMI in screening for metabolic risk factors in 6-10-year-old children. The public health message “keep your waist to less than half your height” can be effective in reducing cardio-metabolic risk because most of these risk factors are already present at a cut point of WHtR ≥ 0.5. However, as this is the first study to correlate the WHtR with inflammatory markers, we recommend further exploration of the use of WHtR in this age group and other population-based samples.
