RESUMO

INTRODUCTION: The WHO Safe Childbirth Checklist (WHO SCC) was developed to accelerate adoption of essential practices that prevent maternal and neonatal morbidity and mortality during childbirth. This study aims to summarise the current landscape of organisations and facilities that have implemented the WHO SCC and compare the published strategies used to implement the WHO SCC implementation in both successful and unsuccessful efforts. METHODS AND ANALYSIS: This scoping review protocol follows the guidelines of the Joanna Briggs Institute. Data will be collected and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews report. The search strategy will include publications from the databases Scopus, PubMed, Embase, CINAHL and Web of Science, in addition to a search in grey literature in The National Library of Australia's Trobe, DART-Europe E-Theses Portal, Electronic Theses Online Service, Theses Canada, Google Scholar and Theses and dissertations from Latin America. Data extraction will include data on general information, study characteristics, organisations involved, sociodemographic context, implementation strategies, indicators of implementation process, frameworks used to design or evaluate the strategy, implementation outcomes and final considerations. Critical analysis of implementation strategies and outcomes will be performed with researchers with experience implementing the WHO SCC. ETHICS AND DISSEMINATION: The study does not require an ethical review due to its design as a scoping review of the literature. The results will be submitted for publication to a scientific journal and all relevant data from this study will be made available in Dataverse.

RESUMO

OBJECTIVE: To assess trends in childbirth at a hospital-birth center among women living in Compañeros En Salud (CES)-affiliated communities in Chiapas, Mexico and explore barriers to childbirth care. Our hypothesis was that despite interventions to support and incentivize childbirth at the hospital-birth center, the proportion of births at the hospital-birth center among women from Compañeros En Salud-affiliated communities has not significantly changed after two years. We suspected that this may be due to structural factors impacting access to care and/or perceptions of care impacting desire to deliver at the birth center. DESIGN: This explanatory mixed-methods study included a retrospective Compañeros En Salud maternal health census review followed by quantitative surveys and semi-structured qualitative interviews. PARTICIPANTS AND SETTING: Participants were women living in municipalities in the mountainous Sierra Madre region of Chiapas, Mexico who received prenatal care in one of 10 community clinics served by Compañeros En Salud. Participants were recruited if they gave birth anywhere other than the primary-level rural hospital and adjacent birth center supported by Compañeros En Salud, either at home or at other facilities. MEASUREMENTS: We compared rates of birth at the hospital-birth center, other health facilities, and at home from 2017-2018. We conducted surveys and interviews with women who gave birth between January 2017-July 2018 at home or at facilities other than the hospital-birth center to understand perceptions of care and decision-making surrounding childbirth location. FINDINGS: We found no significant difference in rates of overall number of women birthing at the hospital-birth center from Compañeros En Salud-affiliated communities between 2017 and 2018 (p=0.36). Analysis of 158 surveys revealed distance (30.4%), time (27.8%), and costs (25.9%) as reasons for not birthing at the hospital-birth center. From 27 interviews, negative perceptions and experiences of the hospital included low-quality and disrespectful care, low threshold for medical interventions, and harm and suffering. Partners or family members influenced most decisions about childbirth location. KEY CONCLUSIONS: Interventions to minimize logistical barriers may not be sufficient to overcome distance and perceptions of low-quality, disrespectful care. IMPLICATIONS FOR PRACTICE: Better understanding of complex decision-making around childbirth will guide Compañeros En Salud in developing interventions to further meet the needs and preferences of birthing women in rural Chiapas.

RESUMO

OBJECTIVE: The WHO Safe Childbirth Checklist (SCC) is a promising initiative for safety in childbirth care, but the evidence about its impact on clinical outcomes is limited. This study analysed the impact of SCC on essential birth practices (EBPs), obstetric complications and adverse events (AEs) in hospitals of different profiles. DESIGN: Quasi-experimental, time-series study and pre/post intervention. SETTING: Two hospitals in North-East Brazil, one at a tertiary level (H1) and another at a secondary level (H2). PARTICIPANTS: 1440 women and their newborns, excluding those with congenital malformations. INTERVENTIONS: The implementation of the SCC involved its cross-cultural adaptation, raising awareness with videos and posters, learning sessions about the SCC and auditing and feedback on adherence indicators. PRIMARY AND SECONDARY OUTCOME MEASURES: Simple and composite indicators related to seven EBPs, 3 complications and 10 AEs were monitored for 1 year, every 2 weeks, totalling 1440 observed deliveries. RESULTS: The checklist was adopted in 83.3% (n=300) of deliveries in H1 and in 33.6% (n=121) in H2. The hospital with the highest adoption rate for SCC (H1) showed greater adherence to EBPs (improvement of 50.9%;p<0.001) and greater reduction in clinical outcome indicators compared with its baseline: percentage of deliveries with severe complications (reduction of 30.8%;p=0.005); Adverse Outcome Index (reduction of 25.6%;p=0.049); Weighted Adverse Outcome Score (reduction of 39.5%;p<0.001); Severity Index (reduction of 18.4%;p<0.001). In H2, whose adherence to the SCC was lower, there was an improvement of 24.7% compared with before SCC implementation in the composite indicator of EBPs (p=0.002) and a reduction of 49.2% in severe complications (p=0.027), but there was no significant reduction in AEs. CONCLUSIONS: A multifaceted SCC-based intervention can be effective in improving adherence to EBPs and clinical outcomes in childbirth. The context and adherence to the SCC seem to modulate its impact, working better in a hospital of higher complexity.

RESUMO

Compared to other Mexican states, Chiapas possessed the lowest rate of contraception use among women 15-49 years old (44.6%) in 2018. This convergent mixed-methods study assessed family planning use, perceptions, and decision-making processes among women and men in rural communities where Compañeros En Salud (CES) works in Chiapas, Mexico. We conducted surveys of reproductive-aged women and semi-structured interviews with reproductive-aged women, men, and physicians completing their social-service year in CES communities from 2016 to 2017. Of the 625 survey respondents, 368 (58.9%) reported using contraception. The most common methods were female sterilization (27.7%), bimonthly injection (10.9%), and the implant (10.9%). Interviews were completed with 27 women, 24 men, and 5 physicians and analyzed through an inductive approach. Common reasons for contraception use were preventing pregnancy, lack of resources for additional children, and birth spacing. Adverse effects, influence of male partners, and perceived lack of need emerged as reasons for non-use. Male partners often made the final decision about contraceptive use, while women often chose what method. Physicians reported adverse effects, misconceptions about methods, and lack of women's autonomy as barriers to contraception use. Given misconceptions about contraception methods and the dominant role of men in contraception decision-making, our study illustrates the importance of effective counseling and equitable gender dynamics for family planning programming in rural Chiapas.

RESUMO

Caesarean delivery rates in Mexico are among the highest in the world. Given heightened public and professional awareness of this problem and the updated 2014 national guidelines to reduce the frequency of caesarean delivery, we analysed trends in caesarean delivery by type of facility in Mexico from 2008 to 2017. We obtained birth-certificate data from the Mexican General Directorate for Health Information and grouped the total number of vaginal and caesarean deliveries into five categories of facility: health-ministry hospitals; private hospitals; government employment-based insurance hospitals; military hospitals; and other facilities. Delivery rates were calculated for each category nationally and for each state. On average, 2 114 630 (95% confidence interval, CI: 2 061 487-2 167 773) live births occurred nationally each year between 2008 and 2017. Of these births, 53.5% (1 130 570; 95% CI: 1 108 068-1 153 072) were vaginal deliveries, and 45.3% (957 105; 95% CI: 922 936-991 274) were caesarean deliveries, with little variation over time. During the study period, the number of live births increased by 4.4% (from 1 978 380 to 2 064 507). The vaginal delivery rate decreased from 54.8% (1 083 331/1 978 380) to 52.9% (1 091 958/2 064 507), giving a relative percentage decrease in the rate of 3.5%. The caesarean delivery rate increased from 43.9% (869 018/1 978 380) to 45.5% (940 206/2 064 507), giving a relative percentage increase in the rate of 3.7%. The biggest change in delivery rates was in private-sector hospitals. Since 2014, rates of caesarean delivery have fallen slightly in all sectors, but they remain high at 45.5%. Policies with appropriate interventions are needed to reduce the caesarean delivery rate in Mexico, particularly in private-sector hospitals.


Les taux d'accouchements par césarienne au Mexique sont parmi les plus élevés au monde. Au vu de la sensibilisation accrue de la population et des professionnels à ce problème et de la mise à jour des directives nationales de 2014 visant à diminuer la fréquence des accouchements par césarienne, nous avons analysé l'évolution des accouchements par césarienne selon le type d'établissement entre 2008 et 2017 au Mexique. Nous avons obtenu des données issues d'actes de naissance auprès de la Direction générale mexicaine des informations sur la santé et regroupé le nombre total d'accouchements par voie basse et par césarienne en cinq catégories d'établissement: hôpitaux relevant du ministère de la Santé, hôpitaux publics, hôpitaux relevant de l'assurance liée à l'emploi public, hôpitaux militaires et autres établissements. Les taux d'accouchements ont été calculés pour chaque catégorie à l'échelle nationale et pour chaque État. En moyenne, 2 114 630 (intervalle de confiance, IC, à 95%: 2 061 487-2 167 773) naissances vivantes ont eu lieu chaque année entre 2008 et 2017 à l'échelle nationale. Parmi ces naissances, 53,5% (1 130 570; IC à 95%: 1 108 068-1 153 072) étaient des accouchements par voie basse, et 45,3% (957 105; IC à 95%: 922 936-991 274) étaient des accouchements par césarienne, avec peu de variations dans le temps. Au cours de la période étudiée, le nombre de naissances vivantes a augmenté de 4,4% (de 1 978 380 à 2 064 507). Le taux d'accouchements par voie basse est passé de 54,8% (1 083 331/1 978 380) à 52,9% (1 091 958/2 064 507), ce qui correspond à une diminution relative du taux de 3,5%. Le taux d'accouchements par césarienne est passé de 43,9% (869 018/1 978 380) à 45,5% (940 206/2 064 507), ce qui correspond à une augmentation relative du taux de 3,7%. Le changement le plus important concernant les taux d'accouchements a été constaté dans les hôpitaux du secteur privé. Depuis 2014, les taux d'accouchements par césarienne ont légèrement diminué dans tous les secteurs, mais demeurent élevés (45,5%). Des politiques et des interventions appropriées sont nécessaires pour réduire le taux d'accouchements par césarienne aux Mexique, en particulier dans les hôpitaux de secteur privé.


Las tasas de parto por cesárea en México están entre las más altas del mundo. Dada la creciente concienciación pública y profesional sobre este problema y las directrices nacionales actualizadas de 2014 para reducir la frecuencia de los partos por cesárea, se analizaron las tendencias de los partos por cesárea según el tipo de establecimiento en México entre 2008 y 2017. Se obtuvieron datos de los certificados de nacimiento de la Dirección General de Información Sanitaria de México y se agrupó el número total de partos vaginales y por cesárea en cinco categorías de establecimientos: hospitales del ministerio de salud pública, hospitales privados, hospitales gubernamentales para asegurados por empleo, hospitales militares y otras instalaciones. Se calcularon los índices de partos para cada categoría a nivel nacional y según cada estado. De media, 2 114 630 (intervalo de confianza, IC, del 95 %: 2 061 487­2 167 773) nacimientos vivos se produjeron a nivel nacional al año entre 2008 y 2017. De estos nacimientos, el 53,5 % (1 130 570; IC del 95 %: 1 108 068­1 153 072) fueron partos vaginales y el 45,3 % (957 105; IC del 95 %: 922 936­991 274) fueron partos por cesárea, con poca variación a lo largo del tiempo. Durante el periodo de estudio, el número de nacidos vivos aumentó un 4,4 % (de 1 978 380 a 2 064 507). La tasa de partos vaginales disminuyó del 54,8 % (1 083 331/1 978 380) al 52,9 % (1 091 958/2 064 507), lo que supone una disminución porcentual relativa de la tasa del 3,5 %. La tasa de partos por cesárea aumentó del 43,9 % (869 018/1 978 380) al 45,5 % (940 206/2 064 507), lo que representa un aumento porcentual relativo de la tasa del 3,7 %. El mayor cambio en las tasas de partos se produjo en los hospitales del sector privado. Desde 2014, las tasas de parto por cesárea se han reducido ligeramente en todos los sectores, pero siguen siendo elevadas (45,5 %). Se necesitan políticas con intervenciones apropiadas para reducir la tasa de partos por cesárea en México, especialmente en los hospitales del sector privado.

RESUMO

OBJECTIVE: To evaluate changes in quality of care after implementing an adapted safe childbirth checklist (SCC) in Chiapas, Mexico. METHODS: A convergent mixed-methods study was conducted among 447 women in labor who attended a rural community hospital between September 1, 2016, and June 30, 2017. Logistic regression analysis was used to evaluate adherence to evidence-based practices over time, adjusting for provider. Participants were surveyed about their perceptions of care after hospital discharge. A purposefully sampled subgroup also completed in-depth interviews. Thematic analysis was performed to evaluate perceptions of care. RESULTS: 384 (85.9%) women were attended by staff that used the adapted SCC during delivery. Of these, 221 and 28 completed the hospital discharge survey and in-depth interview, respectively. Adherence with offering a birth companion (odds ratio [OR] 3.06, 95% CI 1.40-6.68), free choice of birth position (2.75, 1.21-6.26), and immediate skin-to-skin contact (4.53, 1.97-10.39) improved 6-8 months after implementation. Participants' perceived quality of care improved over time. Provider communication generated positive perceptions. Reprimanding women for arriving in early labor or complaining of pain generated negative perceptions. CONCLUSION: Use of the adapted SCC improved quality of care through increased adherence with essential and respectful delivery practices.

RESUMO

This anthropological study explores why more women in the rural Sierra Madre region of Chiapas, Mexico birth at home rather than at the hospital. Between January and May of 2014, the primary investigator conducted in-depth, semi-structured interviews with twenty-six interlocutors: six parteras (home birth attendants), nine pregnant women, four mothers, four healthcare providers, and three local government leaders. Participant observation occurred in the health clinic, participants' homes, and other spaces in a community with a population of 1,188 people. Drawing from narrative analysis, the findings suggest that women face structural obstacles to accessing high-quality childbirth care, which lead them to give birth at home instead of the hospital. These obstacles include financial barriers in obtaining facility-based care and poor quality of care, such as mistreatment in the facility. The study highlights the importance of centreing community narratives in healthcare programming in order to bridge the implementation gap between women in rural communities, healthcare workers, and policymakers.

RESUMO

GOALS: To evaluate potential risk factors for the development of asparaginase-associated pancreatitis (AAP), we performed a systematic review of the current literature from January 1946 through May 2015. BACKGROUND: Asparaginase, a primary treatment for the most common childhood cancer, acute lymphoblastic leukemia (ALL), is a well-described cause of pancreatitis. Further, pancreatitis is among the most burdensome and common complications of asparaginase treatment and represents a major reason for early-drug termination and inferior outcomes. The literature lacks clarity about the risk factors for AAP, and this knowledge gap has hampered the ability to reliably predict which patients are likely to develop AAP. STUDY: In an expansive screen, 1842 citations were funneled into a review of 59 full articles, of which 10 were deemed eligible based on predetermined inclusion criteria. RESULTS: Of the 10 identified studies, only 2 studies showed that children above 10 years of age had a >2-fold risk of AAP compared with younger children. Patients placed in high-risk ALL categories had a greater incidence of pancreatitis in 2 studies. In addition, use of pegylated asparaginase resulted in a higher incidence of AAP in 1 study. CONCLUSIONS: In this systematic review, older age, asparaginase formulation, higher ALL risk stratification, and higher asparaginase dosing appear to play a limited role in the development of AAP. Further studies are needed to probe the underlying mechanisms contributing to the development of pancreatitis in patients receiving asparaginase.

RESUMO

Purpose The mistreatment of women during childbirth in health facilities is a growing area of research and public attention. Description In many countries, disrespect and abuse from maternal health providers discourage women from seeking childbirth with a skilled birth attendant, which can lead to poor maternal and neonatal outcomes. This commentary highlights examples from three countries-Kenya, Mexico and the United States-and presents different forms of mistreatment during childbirth, which range from physical abuse to non-consented care to discriminatory practices. Assessment Building on the momentum from the United Nations Sustainable Development Goals, the International Federation of Gynecology and Obstetrics, and the Global and Maternal Neonatal Health Conference, the global community has placed respectful maternity care at the forefront of the maternal and neonatal health agenda. Conclusion Research efforts must focus on context-specific patient satisfaction during childbirth to identify areas for quality improvement.

RESUMO

OBJECTIVE: Reduced CD16 expression is associated with neutrophil apoptosis. This study aimed to compare CD16 expression on neutrophils in the vagina from women with normal bacterial flora and with vaginitis. STUDY DESIGN: Vaginal lavages were sampled from volunteers diagnosed with bacterial vaginosis (BV, n=34), vulvovaginal candidiasis (VC, n=43), BV plus VC (BV+VC, n=14), and normal flora (NF, n=51). Neutrophils were identified by expression of CD15, CD16 and CD24 surface markers as assessed by flow cytometry. RESULTS: CD16 expression was elevated in neutrophils from women with vaginitis (BV p<0.0001; VC p=0.01; BV+VC p=0.0027) as compared to women with NF. CONCLUSION: The reduction in CD16 down-regulation is consistent with prolonged neutrophil viability and activity in the vagina of women with vaginitis. This may contribute to greater microbial clearance and, conversely, with inflammation-associated pathology.

RESUMO

OBJECTIVE: To evaluate whether the use of "breathable" panty liners (BPLs) alters the normal vaginal flora, increases the incidence of bacterial vaginosis and/or vaginal candidiasis, or causes vulvar irritation. METHODS: A randomized controlled trial assessed the vaginal ecosystem of women without complaints of vaginal discharge. The study group (n=53) wore BPLs for 10-12 hours each day for 75 consecutive days, whereas the control group (n=54) wore only their usual underwear. At each of 6 visits during 3 menstrual cycles, participants underwent gynecologic examination with colposcopic evaluation and pH measurement, in addition to assessment of vaginal microbial flora, intensity of inflammatory processes, and presence of vaginal candidiasis/bacterial vaginosis in Gram-stained smears. RESULTS: After 75 consecutive days of BPL use, 40/44 (90.9%) and 42/44 (95.5%) women reported no complaints of vaginal discharge or vulvar itching/burning, respectively. There was no significant difference between the study group and the control group with regard to positive vaginal fungus cultures (5/44 [11.4%] vs 8/50 [16.0%]; P=0.7848) or bacterial vaginosis (3/44 [6.8%] vs 2/50 [4.0%]; P=0.7974) at the end of the study period. CONCLUSION: After 75 days of BPL use, there was no significant increase in vulvovaginal candidiasis, bacterial vaginosis, vulvovaginal irritation, or vulvovaginal inflammation.

RESUMO

OBJECTIVES: To establish the frequency of auto-antibodies anti-HSP 70 using ELISA and Western Blot (WB) methods and to compare the results of each method among patients with the Ménière's Disease (MD) and internal ear diseases (IED) who do not fulfill criteria for MD. Sensibility, specificity and predictive values of anti-HSP70 test in diagnosis of MD were calculated. STUDY: Prospective, case-control. METHODS: Blood samples were collected from 31 patients with MD and 78 patients with non Ménière IED. Data regarding cochlear and vestibular symptoms were obtained and blood sample was tested. RESULTS: ELISA tests results were positive in 4(13%) patients and results of WB were positive in 8(26%) patients. Among patients with positive ELISA results, 1 patient presented active disease and in the remaining 3 patients the disease was inactive. Among the 8 WB positive patients, only 2 patients presented active disease. Statistical analyses did not establish any association between serologic findings and clinical factors of MD. CONCLUSION: The presence of anti-HSP70 using the ELISA and the WB methods did not demonstrate clinical value for the diagnosis of MD. We did not find association between idiopathic MD nor unspecific etiology MD and the presence of anti-HSP70 auto-antibodies.

RESUMO

Malaria remains one of the most serious world health problem and the major cause of mortality and morbidity in the endemic regions. Brazil is among the 30 high-burden countries and most of the cases occur in the Legal Amazonian Region. New chemotherapeutical agents are needed for the treatment of malaria. Many plant species are used in traditional medicines of malarious countries and a relatively few number of these have been investigated for evaluation of their antimalarial effect. Still lower is the number of those that have had the active natural compounds isolated and the toxicity determined. This area is, then, of great research interest. discovery project of antimalarial natural products from plants traditionally used to treat malaria must include in vitro and in vivo assays as well as bioguided isolation of active compounds. The final products would be antimalarial chemical entities, potential new drugs or templates for new drugs development, and/or standardized antimalarial extracts which are required for pre-clinical and clinical studies when the aim is the development of effective and safe phythomedicines. This review discusses these two approaches, presents briefly the screening methodologies for evaluation of antimalarial activity and focuses the activity of alkaloids belonging to different structural classes as well as its importance as new antimalarial drugs or leads and chemical markers for phytomedicines.


A malária ainda é um dos mais sérios problemas de saúde pública e a principal causa de mortalidade e morbidade nas regiões endêmicas. O Brasil está entre os 30 países com maior incidência de malária e a maior parte dos casos ocorre na Amazônia Legal. Novos agentes terapêuticos são necessários para o tratamento da malária. Muitas espécies vegetais são utilizadas na medicina tradicional de vários países endêmicos mas é relativamente reduzido o número daquelas que já foram investigadas quanto à sua atividade antimalárica. Menor ainda é o número de espécies das quais foram isoladas substâncias ativas e tiveram sua toxidade determinada. Esta área de pesquisa é, portanto, de alta relevância. Um projeto de descoberta de produtos naturais antimaláricos a partir de plantas de uso tradicional deve incluir ensaios in vitro e in vivo bem como o isolamento biomonitorado de substâncias ativas. Os produtos finais serão substâncias naturais antimaláricas, potenciais fármacos ou protótipos para o desenvolvimento de novos fármacos, e/ou extratos padronizados, com atividade antimalárica, os quais são necessários para estudos pré-clínicos e clínicos quando o objetivo é o desenvolvimento de fitoterápicos (fitomedicamentos) eficazes e seguros. A presente revisão discute estas duas abordagens, apresenta resumidamente as metodologias de bioensaios para avaliação de atividade antimalárica e focaliza a atividade de alcalóides pertencentes a diferentes classes estruturais bem como sua importância como fármacos ou protótipos e como marcadores químicos de fitoterápicos.

RESUMO

Malaria remains one of the most serious world health problem and the major cause of mortality and morbidity in the endemic regions. Brazil is among the 30 high-burden countries and most of the cases occur in the Legal Amazonian Region. New chemotherapeutical agents are needed for the treatment of malaria. Many plant species are used in traditional medicines of malarious countries and a relatively few number of these have been investigated for evaluation of their antimalarial effect. Still lower is the number of those that have had the active natural compounds isolated and the toxicity determined. This area is, then, of great research interest. discovery project of antimalarial natural products from plants traditionally used to treat malaria must include in vitro and in vivo assays as well as bioguided isolation of active compounds. The final products would be antimalarial chemical entities, potential new drugs or templates for new drugs development, and/or standardized antimalarial extracts which are required for pre-clinical and clinical studies when the aim is the development of effective and safe phythomedicines. This review discusses these two approaches, presents briefly the screening methodologies for evaluation of antimalarial activity and focuses the activity of alkaloids belonging to different structural classes as well as its importance as new antimalarial drugs or leads and chemical markers for phytomedicines.

RESUMO

No Estado de São Paulo, existe uma rede extensiva de serviços de Atenção Básica (AB) com perfil organizacional heterogêneo e pouco conhecido. Este estudo objetiva caracterizar a organização dos serviços de AB em 37 municípios do Centro-oeste paulista, como primeira etapa de um projeto de avaliação da qualidade desses serviços. Trata-se de um estudo transversal conduzido mediante questionário estruturado, autorrespondido pelos gerentes e equipes locais, com questões que abordam características institucionais e de organização e gerência do trabalho. Esses questionários foram enviados para 131 UBS, distribuídas em 37 municípios. Obteve-se resposta de 113 unidades (87 por cento) localizadas em 32 municípios (86,4 por cento). Do total de unidades, 57 (50 por cento) são UBS tradicionais, 26 (22,8 por cento), Unidades de Saúde da Família, e 31, (27,2 por cento) organizadas segundo formas mistas. A maioria dos serviços (62 por cento, 70/113) não trabalha com área de abrangência delimitada de modo planejado. Os serviços se polarizam entre aqueles que realizam entre 70 e 100 por cento de consultas médicas agendadas (37,6 por cento, 41/109), e aqueles que realizam entre 70 e 100 por cento de não agendadas (39,4 por cento, 43/109). Não possuem conselhos locais organizados 65 unidades (63,7 por cento, 65/102). Os dados coletados permitem discutir as características dos principais programas, procedimentos e ações realizados pelos serviços. Os perfis organizacionais predominantes apontam a presença de deficiências de estrutura e processo em relação às diretrizes do SUS. O desenvolvimento de instrumentos de autoavaliação permite que as equipes se apropriem, de forma crítica, de seu trabalho, e possam elaborar novos arranjos tecnológicos para melhoria da qualidade.

RESUMO

AIM: To investigate the association between chronic periodontitis (CP) and pre-maturity in a group of Brazilian pregnant women from the State of São Paulo. MATERIALS AND METHODS: One hundred and twenty-four women were investigated consecutively in a cross-sectional study, between December 2003 and May 2005. Sixty-eight women had pre-term labour (PTL) and 56 had term labour. A periodontal examination was carried out to identify the presence of CP. Statistical analysis used the Fisher's exact test or chi(2) for the discrete variables and the Mann-Whitney test for the non-parametric variables. Odds ratio (OR) was calculated with a 95% confidence interval (CI), to evaluate the relation between CP and pre-maturity. RESULTS: Periodontal indicators, such as clinical attachment loss (p<0.0001) and bleeding on probing (p=0.012), were observed more in the PTL group. The presence of CP increased the risk for PTL (OR: 4.7, 95% CI: 1.9-11.9), pre-term birth (PTB; OR: 4.9, 95% CI: 1.9-12.8) and low birth weight (<2500 g; OR: 4.2, 95% CI: 1.3-13.3). The pregnant women with PTL presented low levels of schooling (p=0.029) and the lowest number of pre-natal appointments (p=0.0001) when compared with those with term labour. CONCLUSION: CP is strongly associated with PTL, PTB and low birth weight in a group of Brazilian pregnant women. These data point to the necessity of regularly investigating CP during pregnancy.

RESUMO

Sour cassava starch is a traditional fermented food used in the preparation of fried foods and baked goods such as traditional cheese breads in Brazil. Thirty samples of sour cassava starch were collected from two factories in the state of Minas Gerais. The samples were examined for the presence of lactic acid bacteria, yeasts, mesophilic microorganisms, Bacillus cereus and faecal coliforms. Lactic acid bacteria and yeasts isolates were identified by biochemical tests, and the identities were confirmed by molecular methods. Lactobacillus plantarum and Lactobacillus fermentum were the prevalent lactic acid bacteria in product from both factories, at numbers between 6.0 and 9.0 log cfu g(-)(1). Lactobacillus perolans and Lactobacillus brevis were minor fractions of the population. Galactomyces geothricum and Issatchenkia sp. were the prevalent yeasts at numbers of 5.0 log cfu g(-)(1). A species similar to Candida ethanolica was frequently isolated from one factory. Mesophilic bacteria and amylolytic microorganisms were recovered in high numbers at all stages of the fermentation. B. cereus was found at low numbers in product at both factories. The spontaneous fermentations associated with the production of sour cassava starch involve a few species of lactic acid bacteria at high numbers and a variety of yeasts at relatively low numbers.

RESUMO

The present study reports field data of ticks infesting wild carnivores captured from July 1998 to September 2004 in Brazil. Additional data were obtained from one tick collection and from previous published data of ticks on carnivores in Brazil. During field work, a total of 3437 ticks were collected from 89 Cerdocyon thous (crab-eating fox), 58 Chrysocyon brachyurus (maned wolf), 30 Puma concolor (puma), 26 Panthera onca (jaguar), 12 Procyon cancrivorus (crab-eating raccoon), 4 Speothos venaticus (bush dog), 6 Pseudalopex vetulus (hoary fox), 6 Nasua nasua (coati), 6 Leopardus pardalis (ocelot), 2 Leopardus tigrinus (oncilla), 1 Leopardus wiedii (margay), 1 Herpailurus yagouaroundi (jaguarundi), 1 Oncifelis colocolo (pampas cat), 1 Eira barbara (tayara), 1 Galictis vittata (grison), 1 Lontra longicaudis (neotropical otter), and 1 Potus flavus (kinkajou). Data obtained from the Acari Collection IBSP included a total of 381 tick specimens collected on 13 C. thous, 8 C. brachyurus, 3 P. concolor, 10 P. onca, 3 P. cancrivorus, 4 N. nasua, 1 L. pardalis, 1 L. wiedii, 4 H. yagouaroundi, 1 Galictis cuja (lesser grison), and 1 L. longicaudis. The only tick-infested carnivore species previously reported in Brazil, for which we do not present any field data are Pseudalopex gymnocercus (pampas fox), Conepatus chinga (Molina's hog-nosed skunk), and Conepatus semistriatus (striped hog-nosed skunk). We report the first tick records in Brazil on two Felidae species (O. colocolo, H. yagouaroundi), two Canidae species (P. vetulus, S. venaticus), one Procyonidae species (P. flavus) and one Mustelidae (E. barbara). Tick infestation remains unreported for 5 of the 26 Carnivora species native in Brazil: Oncifelis geoffroyi (Geoffroy's cat), Atelocynus microtis (short-eared dog), Pteronura brasiliensis (giant otter), Mustela africana (Amazon weasel), and Bassaricyon gabbii (olingo). Our field data comprise 16 tick species represented by the genera Amblyomma (12 species), Ixodes (1 species), Dermacentor (1 species), Rhipicephalus (1 species), and Boophilus (1 species). Additional 5 tick species (3 Amblyomma species and 1 species from each of the genera Ixodes and Ornithodoros) were reported in the literature. The most common ticks on Carnivora hosts were Amblyomma ovale (found on 14 host species), Amblyomma cajennense (10 species), Amblyomma aureolatum (10 species), Amblyomma tigrinum (7 species), Amblyomma parvum (7 species), and Boophilus microplus (7 species).

RESUMO

Rifalazil, also known as KRM-1648 or benzoxazinorifamycin, is a new semisynthetic rifamycin with a long half-life of approximately 60 h. Rifalazil has potent bactericidal activity against Mycobacterium tuberculosis in vitro and in animal models of tuberculosis (TB). Prior studies in healthy volunteers showed that once-weekly doses of 25 to 50 mg of rifalazil were well tolerated. In this randomized, open-label, active-controlled phase II clinical trial, 65 subjects with sputum smear-positive pulmonary TB received one of the following regimens for the first 2 weeks of therapy: 16 subjects received isoniazid (INH) (5 mg/kg of body weight) daily; 16 received INH (5 mg/kg) and rifampin (10 mg/kg) daily; 17 received INH (5 mg/kg) daily plus 10 mg of rifalazil once weekly; and 16 received INH (5 mg/kg) daily and 25 mg of rifalazil once weekly. All subjects were then put on 6 months of standard TB therapy. Pretreatment and day 15 sputum CFU of M. tuberculosis were measured to assess the bactericidal activity of each regimen. The number of drug-related adverse experiences was low and not significantly different among treatment arms. A transient decrease in absolute neutrophil count to less than 2,000 cells/mm(3) was detected in 10 to 20% of patients in the rifalazil- and rifampin-containing treatment arms without clinical consequences. Decreases in CFU counts were comparable among the four treatment arms; however, the CFU results were statistically inconclusive due to the variability in the control arms. Acquired drug resistance did not occur in any patient. Studies focused on determining a maximum tolerated dose will help elucidate the full anti-TB effect of rifalazil.
