Abstract: background: analyses on mortality rate due to diseases when outcome depends on proper, timely medical intervention may point out the vulnerabilities and inequity associated to health care access. ischemic heart diseases will act as models for such assessment. objective: the present study investigates factors associated to the hospital death rate of patients admitted to hospital due to acute myocardial infarction (ami) and heart failure (hf), and whether admittance through belo horizonte municipal health office (smsa-bh) admission center (ac) was in any way associated to hospital death after adjustment of relevant factors. methods: data obtained from the hospital admission authorizations (aih) and requests for hospital beds at smsa data base on latest hospital admissions based on ami or hf diagnostic hypotheses. multivariate analysis was conducted to investigate risk factors for hospital death. results: no association was found between hospital admittance access and hospital death risk from those causes. multivariate analysis showed higher death risk for 60 and 60+ year-old patients (or=2.9), ami diagnostic hypothesis (or=3.0), the need for icu care (or=1.6), females (or=1.4), surgery type (or=1.9), and public health service hospital (or=3.5). hospital admissions due to ami on weekends also showed higher death risk for death (or=1.7). conclusion: further investigation is necessary in order to evaluate the kind of medical assistance provided on weekends at public hospitals. other hospital factors are to be taken into account, as well as patients and assistance procedures, as subsidies for proposals to ensure higher equity and quality standard for public health services.

Abstract: the hospital admissions center in belo horizonte, minas gerais state, brazil, aims to assure fast, timely, and equitable access to hospitalization services through the unified national health system. however, many patients are admitted directly to the hospitals, without going through the admissions center. this study compared the characteristics of hospitalizations in belo horizonte in 2002 according to type of access. all admissions for acute myocardial infarction and acute coronary disease were included. of 3,705 admissions, 24.9% were processed through the hospital admissions center and 75.1% through direct access. direct hospitalizations were more common as compared to processing by the hospital admissions center for patients > 70 years ), those with presumptive diagnosis of acute coronary disease, to the surgical department, and on weekends. admissions via the hospital admissions center were more common than direct access for patients residing outside belo horizonte, at non-public hospitals, and for the intensive care unit. length-of-stay also varied according to type of access. the results confirm differences in the characteristics of admissions according to the two types of access.

Abstract: context and objective: morbidly obese individuals are major consumers of healthcare services, with high associated costs. bariatric surgery is an alternative for improving these individuals' comorbidities. there are no studies comparing costs before and after bariatric surgery in brazil. the aim here was to analyze results relating to healthcare usage and direct costs among morbidly obese patients undergoing bariatric surgery. design and setting: historical cohort study on patients receiving healthcare through a private health plan in belo horizonte, minas gerais. methods: all healthcare services and their associated costs were included in the analysis: hospitalization, hospital stay, elective outpatient consultations, emergency service usage and examinations. the analyses were treated as total when including the whole years before and after surgery, or partial when excluding the three-month periods adjacent to the operation. results: for 382 obese patients who underwent open bariatric operations, there were 53 hospitalizations one year before and 95 one year after surgery (p = 0.013). gastrointestinal complications were the main indications for post-procedure hospitalizations. the partial average cost almost doubled after the operation (us$ 391.96 versus us$ 678.31). in subgroup analysis, the costs from patients with gastrointestinal complications were almost four times greater after bariatric surgery. even in the subgroup without complications, the partial average cost remained significantly higher. conclusion: although bariatric surgery is the only path towards sustained weight loss for morbidly obese patients, the direct costs over the first year after the procedure are greater. further studies, with longer follow-up, might elucidate whether long-term reversal of this trend would occur

Abstract: Foi realizado um levantamento das helmintoses intestinais em 18.973 escolares do primeiro grau (7 a 14 anos), da rede pública do Estado de Minas Gerais, utilizando o método de Kato-Katz de exame de fezes (duas laminas por amostra). Foram estudadas 3 mesorregi es: Triangulo Mineiro/Alto Paranaíba (60 municípios), Noroeste de Minas (13) e Sul/Sudoeste (144). Entre os escolares examinados, 15.545 (82%) estavam negativos, 2.863 (15%) monoparasitados e 565 (3%) poliparasitados. A prevalência de A. lumbricoides foi de 10,3%, de T. trichiura 4,7%, de ancilostomídeos 2,9%, de E. vermicularis 1,2%, de H. nana 0,4% e de Taenia sp 0,2%. As maiores prevalências de helmintos/mesorregi o foram de 24,2% para T. trichiura e 18,7% para A. lumbricoides (Sul/Sudoeste) e 12,1% para ancilostomídeos e 0,7% para Taenia sp (Noroeste de Minas). As helmintoses intestinais continuam sendo um grave problema de saúde pública, inclusive em áreas onde as condi es socioecon micas s o mais favoráveis.

Abstract: Entre janeiro e maio de 1996, 156 idosos morreram na Clínica Santa Genoveva, no Rio de Janeiro. A mortalidade mais alta foi observada em maio: 143/1.000 interna es. Isto resultou no fechamento da clínica pelo Ministério da Saúde. O objetivo deste trabalho é verificar, utilizando-se dados do Sistema de Informa es Hospitalares do Sistema único de Saúde (SIH-SUS), se os óbitos ocorridos na clínica em 1996 representavam uma exce o ou se refletiam condi es já existentes. O período do estudo foi de janeiro/1993 a maio/1996. A metodologia da investiga o incluiu 1) análise da série histórica do número e das taxas mensais brutas de mortalidade e 2) compara es destas com aquelas de 15 hospitais definidos como referência. O risco de morrer na clínica foi superior ao dos hospitais de referência em 28 dos 41 meses considerados. Os maiores riscos relativos foram observados em janeiro de 1993 (RRbruto = 2,23; IC-95% = 1,56-3,14) e maio de 1996 (RRajustado = 2,73; IC-95% = 1,88-3,95). Os resultados mostram que a alta mortalidade na clínica já vinha ocorrendo desde 1993. A utiliza o adequada do SIH-SUS poderia ter antecipado e evitado o excesso de mortalidade só identificado em meados de 1996.

Massara Cristiano Lara,Ferreira Rafaela Salgado,Andrade Luiz Dias de,Guerra Henrique Leonardo
Cadernos de Saúde Pública , 2003,
Abstract: A infec o por Ascaris lumbricoides decorre da ingest o de ovos embrionados deste parasita, o que justifica a pesquisa de substancias que tenham efeito deletério sobre estes ovos. Nosso objetivo foi estudar a a o de 16 produtos detergentes e desinfetantes, de uso doméstico e laboratorial, sobre a embriogênese deste helminto. Crian as portadoras desta infec o foram tratadas com levamisol e os vermes fêmeas expelidos foram recolhidos e dissecados, para obten o dos ovos intra-uterinos. Os ovos foram postos em contato com os produtos em diversas dilui es e tempos, lavados e incubados a 28masculineC, por 20 dias, para teste da viabilidade e determina o da porcentagem de embrionamento. Apenas um produto inibiu completamente o embrionamento dos ovos, em todos os tempos e dilui es testados. Cinco produtos inibiram o embrionamento dos ovos em mais de 50%, seis inibiram o embrionamento em menos de 50% e três n o tiveram efeito sobre o embrionamento dos ovos. Por outro lado, com um produto observou-se aumento da porcentagem de embrionamento dos ovos em rela o aos controles.

Abstract: ascaris lumbricoides infection is acquired via ingestion of embryonated eggs of the parasite, thus justifying the search for ovicidal compounds. we studied the effect of 16 household and laboratory detergents and disinfectants on the embryogenesis of this helminth. children carrying this infection were treated with levamisole. eliminated female worms were collected and dissected to obtain eggs from the uteri. the eggs were placed in contact with various products at different dilutions and for various periods of time. after washing, eggs were incubated at 28oc for 20 days, for viability tests and to determine the embryonation rate. only one product completely inhibited the embryonation of eggs at every dilution and for every time period tested. five products inhibited more than 50% of embryonation, while six inhibited less than 50%. three products showed no effect on embryonation, while for one the percentage of embryonated eggs was higher than in the control tubes.
