Prevalência da infecção por Chlamydia Trachomatis em mulheres atendidas no Programa de rastreamento do câncer de colo do útero

Genital infection with Chlamydia trachomatis is now recognized as one of the most prevalent sexually transmitted infections (STDs). Despite major advances in laboratory diagnosis techniques, primarily the character of asymptomatic chlamydial infection in both men and in women constitutes the basis for the formation of reservoirs that perpetuate transmission and acquisition of this and other STDs. The asymptomatic in women favors the rise of infection to the upper genital tract, causing injuries that can result in infertility. An examination of population screening for early detection and treatment of asymptomatic infections is the key step in combating this major public health problem. The present study aimed to evaluate the prevalence of infection by C. trachomatis in sexually active women attended the screening program for cervical cancer of the uterus in health facilities in municipalities in different regions of the State of Rio Grande do Norte, and identify factors that may contribute to the spread of this pathogen and its relationship with the lesions of the uterine cervix. It is a cross-sectional study aimed at detecting the presence of genital tract infection by C. trachomatis either in isolated form or in association with human papilloma virus (HPV) infection in asymptomatic women. Were included in this study, a total sample of 1,134 women aged 13-76, mean 34.4 years, from March 2008 to September 2012. Specimens containing exfoliated cells of the epithelium of the uterine cervix were analyzed by examining Pap cytology for the detection of possible injuries, and the polymerase chain reaction (PCR) for detection of plasmid DNA from C. trachomatis and HPV. Infection with C. trachomatis was detected with overall prevalence rate of 8.1% in the isolated form and 2.8% in co-infection with HPV. The infection was detected in 7.4% of women with normal cytology 11.5% of those with atypical cells of undetermined significance (ASC-US) and 16.7% of those with low-grade squamous intraepithelial lesion (LSIL). We observed an association between C. trachomatis and incidence of low-grade squamous intraepithelial lesion (LSIL). The genital tract infection by C. trachomatis alone was associated with education level, ethnicity and parity, revealing that women with higher education, those of non-white ethnicity and those who had three or more pregnancies were more likely to acquire infection. Levels very close to statistical significance were observed for chronological age, age at first sexual intercourse and first pregnancy. There was no association with marital status, number of sexual partners. Co-infection with C. trachomatis and HPV was detected in 2.3% of women with normal cytology, who had 5.1% in ASC-US and 10.4% in those with LSIL. No association was found between infection C. trachomatis and increased risk of HPV infection, but women with simultaneous infection by both pathogens showed greater risk for LSIL. Co-infection was more prevalent among single women, who had in the first sexual intercourse under 18 years and those who had two or more sexual partners over a lifetime

SISOnt: sistema de informação em saúde baseado em ontologias

The sharing of knowledge and integration of data is one of the biggest challenges in health and essential contribution to improve the quality of health care. Since the same person receives care in various health facilities throughout his/her live, that information is distributed in different information systems which run on platforms of heterogeneous hardware and software. This paper proposes a System of Health Information Based on Ontologies (SISOnt) for knowledge sharing and integration of data on health, which allows to infer new information from the heterogeneous databases and knowledge base. For this purpose it was created three ontologies represented by the patterns and concepts proposed by the Semantic Web. The first ontology provides a representation of the concepts of diseases Secretariat of Health Surveillance (SVS) and the others are related to the representation of the concepts of databases of Health Information Systems (SIS), specifically the Information System of Notification of Diseases (SINAN) and the Information System on Mortality (SIM)

Usefulness of Mycobacterium tuberculosis molecular typing in a tuberculosis low-endemic agro-industrial setting of Brazil

To highlight the transmission and major phylogenetic clades of Mycobacterium tuberculosis, a retrospective study was carried out at two health facilities in a small agro-industrial area in São Paulo, Brazil, that has a low tuberculosis incidence rate. IS6110-RFLP and spoligotyping were performed on the isolates, with the former revealing that 31.3% (35/112) of strains were clustered. Epidemiological links were found in 16 of the 35 clustered patients and were associated with transmission among patients living in public housing. Spoligotyping grouped 62.8% of the strains. The T genetic family predominated among the isolates. Of interest is that five strains had a pattern characteristic of African or Asian origin (ST535), and two others were of the rare localized type ST1888 (BRA, VEN). In addition, three new types-1889, 1890, and 1891-were identified. Spoligotyping showed that some ST may be circulating to or from Brazil, and RFLP revealed ongoing transmission in inadequately ventilated public-housing buildings. This may point to a failure in tuberculosis control policy.

Medicamentos utilizados no controle da hipertensão no Distrito Administrativo DAGUA em Belém, PA

A Hipertensão Arterial Sistêmica (HAS) é uma condição associada a elevados índices de morbidade e mortalidade com baixas taxas de controle, sendo um dos mais importantes problemas de saúde publica no mundo. Trata-se de um estudo descritivo exploratório de natureza transversal e observacional, realizado em cinco unidades de saúde do Distrito Administrativo DAGUA, localizadas no municipio de Belém-PA, no período entre março de 2010 a agosto de 2011. A pesquisa também realizou estudo documental onde informações foram transcritas, para formulários da pesquisa. Este estudo buscou conhecer a logística de suprimento e o perfil de utilização de medicamentos para o controle da Pressão Arterial Sistêmica no Distrito Administrativo DAGUA. Para tanto foram investigados o perfil sóciodemográfico dos participantes do programa HIPERDIA, quais os medicamentos disponibilizados pela rede municipal de saúde para o tratamento da HAS, assim como a logística empregada pelo município para a disponbibilidade de acesso aos mesmos. A população deste estudo se caracterizou por ser principalmente idosa, com baixa escolaridade e predominantemente formada por pardos. Observou-se, que 53,78% dos pacientes faz uso de monoterapia e 46,22% de politerapia. 36,84% utiliza somente Captopril. 65,31% dos pacientes que fazem politerapia utilizam a associação de Captopril e hidroclorotiazida. Não se encontrou correlações significativas entre os aspectos socioeconômicos dos participantes e o controle dos níveis de pressão arterial. O conhecimento sobre a HAS não influenciou os resultados da PA. 51,96% dos pacientes apresenta PA não controlada. Em função da falta de abastecimento de medicamentos nas unidades de saúde e do perfil socioeconômico dos usuários, o Programa Farmácia Popular do Brasil apresenta-se como uma importante estrátegia para o acesso desses pacientes ao seu tratamento. Por fim, resumindo os achados, observou-se que o ciclo logístico da Assistência Farmacêutica em Belém – em especial as etapas de programação, aquisição e dispensação de medicamentos – não respeita o atual arcabouço legal que regulamenta a Política Nacional de Assistência Farmacêutica. Contatou-se falta de uniformização entre os medicamentos programados para unidades localizadas na mesma região, além da grande diferença entre as condições de compra dos medicamentos quando comparado a outras licitações, que chegam a gerar diferenças de preços de até 3000%. Conclui-se que que a gestão técnica da assistência farmacêutica no município de Belém é inefetiva e ineficiente para o cuidado de pacientes portadores de Hipertensão Arterial Sistêmica.

Fatores interferentes nas estratégias de controle do câncer do colo do útero com ênfase na infecção pelo HPV

O câncer do colo do útero é um dos graves problemas de saúde pública no mundo e no Brasil. O exame colpocitológico e a educação em saúde são estratégias fundamentais para o êxito do programa de prevenção do câncer do colo do útero nos serviços de saúde pública. Foi realizado um estudo transversal e analítico, com o objetivo de identificar e discutir os fatores interferentes nas estratégias de controle do câncer do colo do útero, com ênfase na infecção pelo vírus HPV, sob a perspectiva das clientes do programa. A população do estudo foi de 858 mulheres atendidas nas unidades de saúde pública, em duas estratégias de Saúde da Família e três unidades básicas de saúde, sendo uma um Centro de Saúde Escola, no Município de Belém/PA. Os dados foram coletados através de entrevista. Entre os fatores que interferem negativamente na efetividade das estratégias do respectivo programa estão incluídos: o perfil de clientela quanto a idade, grau de instrução e renda familiar; as características de atendimento e tipo de demanda do programa; o conhecimento de mulheres sobre câncer do colo do útero, neoplasia intraepitelial cervical, vírus HPV e vacina anti-hpv e; o uso das práticas educativas pelas unidades de saúde deste estudo. Conclui-se que intervenções na organização dos serviços de saúde pública podem contribuir na efetividade dessas estratégias, como a efetivação da busca ativa para melhorar o acesso das mulheres nas faixas etárias de maior prevalência de infecção pelo HPV e das mulheres em atraso com o exame colpocitológico anual. Assim como, o estabelecimento das práticas educativas como um recurso organizacional permanente para elevar o nível de conhecimento de mulheres sobre câncer do colo do útero e vírus HPV; além de tornar o monitoramento efetivo de mulheres sob controle anual. Enfim buscar ferramentas organizacionais na perspectiva da prevenção primária e secundária importantes para o controle do câncer do colo do útero e do vírus HPV.

Santa Casa de Misericórdia e as políticas higienistas em Belém do Pará no final do século XIX

O artigo analisa a relação entre as políticas higienistas que vigoraram na cidade de Belém ao final do século XIX e a expansão das atividades da Santa Casa de Misericórdia do Pará. Considerada uma das primeiras instituições hospitalares da então Província do Grão-Pará, a Irmandade, além de seu hospital próprio, administrou diversos outros estabelecimentos de saúde na capital. O estudo de seu deslocamento físico permite o “desenho” de três núcleos da Saúde em Belém: Pioneiro, de Expansão e da Santa Casa, que reforçam os vetores de crescimento da cidade. A expansão de suas atividades se configura como ampliação da Misericórdia para atender os desvalidos e enfermos, que precede a instauração de um sistema de saúde pública no Pará.

Classification and regression tree (CART) model to predict pulmonary tuberculosis in hospitalized patients

Background: Tuberculosis (TB) remains a public health issue worldwide. The lack of specific clinical symptoms to diagnose TB makes the correct decision to admit patients to respiratory isolation a difficult task for the clinician. Isolation of patients without the disease is common and increases health costs. Decision models for the diagnosis of TB in patients attending hospitals can increase the quality of care and decrease costs, without the risk of hospital transmission. We present a predictive model for predicting pulmonary TB in hospitalized patients in a high prevalence area in order to contribute to a more rational use of isolation rooms without increasing the risk of transmission. Methods: Cross sectional study of patients admitted to CFFH from March 2003 to December 2004. A classification and regression tree (CART) model was generated and validated. The area under the ROC curve (AUC), sensitivity, specificity, positive and negative predictive values were used to evaluate the performance of model. Validation of the model was performed with a different sample of patients admitted to the same hospital from January to December 2005. Results: We studied 290 patients admitted with clinical suspicion of TB. Diagnosis was confirmed in 26.5% of them. Pulmonary TB was present in 83.7% of the patients with TB (62.3% with positive sputum smear) and HIV/AIDS was present in 56.9% of patients. The validated CART model showed sensitivity, specificity, positive predictive value and negative predictive value of 60.00%, 76.16%, 33.33%, and 90.55%, respectively. The AUC was 79.70%. Conclusions: The CART model developed for these hospitalized patients with clinical suspicion of TB had fair to good predictive performance for pulmonary TB. The most important variable for prediction of TB diagnosis was chest radiograph results. Prospective validation is still necessary, but our model offer an alternative for decision making in whether to isolate patients with clinical suspicion of TB in tertiary health facilities in countries with limited resources.

Use of modern and traditional products to self-treat symptoms of sexually transmitted infections in South African women

The objective of the study is to investigate products used by women self-treating symptoms of reproductive tract infections (RTIs), including sexually transmitted infections (STIs), and their methods of administration. A household survey using a multi-stage cluster sample design was undertaken in KwaZulu-Natal, South Africa. Women aged 18-60 years were interviewed (n = 867) and information was collected on demographics, reproductive health and sexual behaviours. A fifth of women reported having RTI/STI symptoms (20.5%), of whom 41.9% were treating these symptoms (mostly discharge [79.1%], ulcers [6.8%] and itching [7.7%]). Only three women were using medication prescribed by a health provider, while the remainder were self-treating using traditional medicines and modern products, including antiseptics, soaps, petroleum jelly, menthol creams and alum. Products were administered in various ways. Although RTI/STI treatment is widely available and free in public health facilities, many women are still self-treating. Potential harm of products for self-treatment requires further investigation and efforts should be made to improve STI service uptake.

INTEGRATION D’UN OBSERVATOIRE URBAIN SUR GOOGLE MAPS : Cas des infrastructures de la santé de la ville de Douala Cameroun

The spectacular advances computer science applied to geographic information systems (GIS) in recent times has favored the emergence of several technological solutions. These developments have given rise to enormous opportunities for digital management of the territory. Among the technological solutions, the most famous Google Maps offers free online mapping dynamic exhaustive of the Maps. In addition to meet the enormous needs of urban indicators geotagged information, we did work on this project “Integration of an urban observatory on Google Maps.” The problem of geolocation in the urban observatory is particularly relevant in the sense that there is currently no data (descriptive and geographical) reliable on the urban sector; we must stick to extrapolate from data old and obsolete. This helps to curb the effectiveness of urban management to make difficult investment programming and to prevent the acquisition of knowledge to make cities engines of growth. The use of a geolocation tool coupled to the data would allow better monitoring of indicators Our project's objective is to develop an interactive map server (WebMapping) which map layer is formed from the resources of the Google Maps servers and match information from the field to produce maps of urban equipment and infrastructure of a city data to the client's request To achieve this goal, we will participate in a study of a GPS location of strategic sites in our core sector (health facilities), on the other hand, using information from the field, we will build a postgresql database that will link the information from the field to map from Google Maps via KML scripts and PHP appropriate. We will limit ourselves in our work to the city of Douala Cameroon with the sectors of health facilities with the possibility of extension to other areas and other cities.

Retention in care during the first 3 years of antiretroviral therapy for women in Malawi's option B+ programme: an observational cohort study

Background Studies of Malawi's option B+ programme for HIV-positive pregnant and breastfeeding women have reported high loss to follow-up during pregnancy and at the start of antiretroviral therapy (ART), but few data exist about retention during breastfeeding and after weaning. We examined loss to follow-up and retention in care in patients in the option B+ programme during their first 3 years on ART. Methods We analysed two data sources: aggregated facility-level data about patients in option B+ who started ART between Oct 1, 2011, and June 30, 2012, at 546 health facilities; and patient-level data from 20 large facilities with electronic medical record system for HIV-positive women who started ART between Sept 1, 2011, and Dec 31, 2013, under option B+ or because they had WHO clinical stages 3 or 4 disease or had CD4 counts of less than 350 cells per μL. We used facility-level data to calculate representative estimates of retention and loss to follow-up. We used patient-level data to study temporal trends in retention, timing of loss to follow-up, and predictors of no follow-up and loss to follow-up. We defined patients who were more than 60 days late for their first follow-up visit as having no follow-up and patients who were more than 60 days late for a subsequent visit as being lost to follow-up. We calculated proportions and cumulative probabilities of patients who had died, stopped ART, had no follow-up, were lost to follow-up, or were retained alive on ART for 36 months. We calculated odds ratios and hazard ratios to examine predictors of no follow-up and loss to follow-up. Findings Analysis of facility-level data about patients in option B+ who had not transferred to a different facility showed retention in care to be 76·8% (20 475 of 26 658 patients) after 12 months, 70·8% (18 306 of 25 849 patients) after 24 months, and 69·7% (17 787 of 25 535 patients) after 36 months. Patient-level data included 29 145 patients. 14 630 (50·2%) began treatment under option B+. Patients in option B+ had a higher risk of having no follow-up and, for the first 2 years of ART, higher risk of loss to follow-up than did patients who started ART because they had CD4 counts less than 350 cells per μL or WHO clinical stage 3 or 4 disease. Risk of loss to follow-up during the third year was low and similar for patients retained for 2 years. Retention rates did not change as the option B+ programme matured. Interpretation Our data suggest that pregnant and breastfeeding women who start ART immediately after they are diagnosed with HIV can be retained on ART through the option B+ programme, even after many have stopped breastfeeding. Interventions might be needed to improve retention in the first year on ART in option B+.

Outcomes and cost effectiveness of treating type 2 diabetes with a nurse case manager following treatment algorithms versus primary care physicians

Background. Diabetes places a significant burden on the health care system. Reduction in blood glucose levels (HbA1c) reduces the risk of complications; however, little is known about the impact of disease management programs on medical costs for patients with diabetes. In 2001, economic costs associated with diabetes totaled $100 billion, and indirect costs totaled $54 billion. ^ Objective. To compare outcomes of nurse case management by treatment algorithms with conventional primary care for glycemic control and cardiovascular risk factors in type 2 diabetic patients in a low-income Mexican American community-based setting, and to compare the cost effectiveness of the two programs. Patient compliance was also assessed. ^ Research design and methods. An observational group-comparison to evaluate a treatment intervention for type 2 diabetes management was implemented at three out-patient health facilities in San Antonio, Texas. All eligible type 2 diabetic patients attending the clinics during 1994–1996 became part of the study. Data were obtained from the study database, medical records, hospital accounting, and pharmacy cost lists, and entered into a computerized database. Three groups were compared: a Community Clinic Nurse Case Manager (CC-TA) following treatment algorithms, a University Clinic Nurse Case Manager (UC-TA) following treatment algorithms, and Primary Care Physicians (PCP) following conventional care practices at a Family Practice Clinic. The algorithms provided a disease management model specifically for hyperglycemia, dyslipidemia, hypertension, and microalbuminuria that progressively moved the patient toward ideal goals through adjustments in medication, self-monitoring of blood glucose, meal planning, and reinforcement of diet and exercise. Cost effectiveness of hemoglobin AI, final endpoints was compared. ^ Results. There were 358 patients analyzed: 106 patients in CC-TA, 170 patients in UC-TA, and 82 patients in PCP groups. Change in hemoglobin A1c (HbA1c) was the primary outcome measured. HbA1c results were presented at baseline, 6 and 12 months for CC-TA (10.4%, 7.1%, 7.3%), UC-TA (10.5%, 7.1%, 7.2%), and PCP (10.0%, 8.5%, 8.7%). Mean patient compliance was 81%. Levels of cost effectiveness were significantly different between clinics. ^ Conclusion. Nurse case management with treatment algorithms significantly improved glycemic control in patients with type 2 diabetes, and was more cost effective. ^
