Intervenções em Dieta e Pressão Arterial na América Latina - Revisão Sistemática e Meta-Análise

Fundamento: Pressão arterial elevada é o principal fator de risco para doenças cardiovasculares. Baixos índices de controle da pressão arterial em populações latino-americanas reforçam a necessidade de reunir evidências sobre terapias eficazes. Objetivo: Avaliar o efeito das intervenções de modificações de dietas sobre pressão arterial em populações latino-americanas. Métodos: Revisão sistemática. Foram pesquisadas diversas bases de dados (MEDLINE-PubMed, Embase, Cochrane Library, CINAHL, Web of Science, Scopus, SciELO, LILACS e BVS) e realizada busca manual até abril de 2013. Foram incluídos estudos paralelos de intervenções em dieta em populações adultas da América Latina reportando pressão arterial (em mmHg) antes e após a intervenção. Resultados: Dos 405 estudos encontrados, 10 ensaios clínicos randomizados foram incluídos e divididos em 3 subgrupos, de acordo com a dieta proposta como intervenção. Houve redução não significativa da pressão arterial sistólica nos subgrupos de substituição mineral -4,82 (IC 95%: -11,36 a 1,73 mmHg) e padrões complexos -3,17 (IC 95%: -7,62 a 1,28 mmHg). Para a pressão arterial diastólica, com exceção do subgrupo de dietas hiperproteicas, todos os subgrupos apresentaram redução significativa, com -4,66 (IC 95%: -9,21 a -0,12 mmHg) e -4,55 (IC 95%: -7,04 a -2,06 mmHg) para substituição mineral e padrões complexos, respectivamente. Conclusão: A evidência disponível sobre os efeitos de alterações de dieta na pressão arterial em populações latino-americanas indica um efeito homogêneo, porém não significativo, para pressão arterial sistólica. Estudos maiores e com maior rigor metodológico são necessários para construção de evidência robusta.

Alcohol Brief Intervention in Primary Care: A Systematic Review

BACKGROUND: The purpose of the present review was to evaluate the evidence of the effectiveness of brief interventions aimed at reducing chronic alcohol use and harm related to alcohol consumption, conducted among individuals actively attending primary care but who were not seeking help for alcohol problems. METHODS: Randomised trials reporting at-least one outcome related to alcohol consumption and conducted in outpatients who were actively attending primary care centre or provider were selected using Cochrane Central Register of Controlled Trials, MEDLINE, PsycINFO, ISI Web of Science, ETOH database, and bibliographies of the retrieved references and previous reviews. Selection and data abstraction were performed independently and in duplicate. We assessed validity of the studies and performed a meta-analysis for studies reporting alcohol consumption at 6 or 12 months follow up. RESULTS: We included 24 reports, reporting results of 19 trials and including 5,639 individuals. Seventeen trials reported a measure of alcohol consumption, eight reporting a significant effect of intervention. The meta-analysis showed a mean pooled difference of -41 (95% CI: −54; −28) g of pure ethanol per week in favour of brief intervention group. Evidences for other outcomes (laboratory values, health related quality of life, morbidity and mortality, health care utilisation) were inconclusive. CONCLUSION: Our systematic review indicated that brief intervention might be effective for both men and women in reducing alcohol consumption compared to a controlled intervention, in a primary health care population. The meta-analysis confirmed the reduction in alcohol consumption at 6 and 12 month. Further research should precise the components of effectiveness of brief intervention and the evidence of effects on morbidity, mortality, and quality of life related outcomes.

Clinician characteristics, communication, and patient outcome in oncology: a systematic review.

OBJECTIVE: The aim of this study was to review the literature on clinician characteristics influencing patient-clinician communication or patient outcome in oncology. METHODS: Studies investigating the association of clinician characteristics with quality of communication and with outcome for adult cancer patients were systematically searched in MEDLINE, PSYINFO, PUBMED, EMBASE, CINHAL, Web of Science and The Cochrane Library up to November 2012. We used the preferred reporting items for systematic reviews and meta-analyses statement to guide our review. Articles were extracted independently by two of the authors using predefined criteria. RESULTS: Twenty seven articles met the inclusion criteria. Clinician characteristics included a variety of sociodemographic, relational, and personal characteristics. A positive impact on quality of communication and/or patient outcome was reported for communication skills training, an external locus of control, empathy, a socioemotional approach, shared decision-making style, higher anxiety, and defensiveness. A negative impact was reported for increased level of fatigue and burnout and expression of worry. Professional experience of clinicians was not related to communication and/or to patient outcome, and divergent results were reported for clinician gender, age, stress, posture, and confidence or self-efficacy. CONCLUSIONS: Various clinician characteristics have different effects on quality of communication and/or patient outcome. Research is needed to investigate the pathways leading to effective communication between clinicians and patients. Copyright © 2013 John Wiley & Sons, Ltd.

Olfaction in eating disorders and abnormal eating behavior: a systematic review.

The study provides a systematic review that explores the current literature on olfactory capacity in abnormal eating behavior. The objective is to present a basis for discussion on whether research in olfaction in eating disorders may offer additional insight with regard to the complex etiopathology of eating disorders (ED) and abnormal eating behaviors. Electronic databases (Medline, PsycINFO, PubMed, Science Direct, and Web of Science) were searched using the components in relation to olfaction and combining them with the components related to abnormal eating behavior. Out of 1352 articles, titles were first excluded by title (n = 64) and then by abstract and fulltext resulting in a final selection of 14 articles (820 patients and 385 control participants) for this review. The highest number of existing literature on olfaction in ED were carried out with AN patients (78.6%) followed by BN patients (35.7%) and obese individuals (14.3%). Most studies were only conducted on females. The general findings support that olfaction is altered in AN and in obesity and indicates toward there being little to no difference in olfactory capacity between BN patients and the general population. Due to the limited number of studies and heterogeneity this review stresses on the importance of more research on olfaction and abnormal eating behavior.

Ageing prisoners' health care: analysing the legal settings in Europe and the United States.

BACKGROUND: Relatively little is known about the current health care situation and the legal rights of ageing prisoners worldwide. To date, only a few studies have investigated their rights to health care. However, elderly prisoners need special attention. OBJECTIVE: The aim of this article is to critically review the health care situation of older prisoners by analysing the relevant national and international legal frameworks with a particular focus on Switzerland, England and Wales, and the United States (U.S.). METHODS: Publications on legal frameworks were searched using Web of Science, PubMed, MEDLINE, HeinOnline, and the National Criminal Justice Reference Service. Searches utilizing combinations of keywords relating to ageing prisoners were performed. Relevant reports and policy documents were obtained in order to understand the legal settings in Switzerland, England and Wales, and the U.S. All articles, reports, and policy documents published in English and German between 1774 to June 2012 were included for analysis. Using a comparative approach, an outline was completed to distinguish positive policies in this area. Regulatory approaches were investigated through evaluations of soft laws applicable in Europe and U.S. Supreme Court judgements. RESULTS: Even though several documents could be interpreted as guaranteeing adequate health care for ageing prisoners, there is no specific regulation that addresses this issue completely. The Vienna International Plan of Action on Ageing contributes the most by providing an in-depth analysis of the health care needs of older persons. Still, critical analysis of retrieved documents reveals the lack of specific legislation regarding the health care for ageing prisoners. CONCLUSION: No consistent regulation delineates the provision of health care for ageing prisoners. Neither national nor international institutions have enforceable laws that secure the precarious situation of older adults in prisons. To initiate a change, this work presents critical issues that must be addressed to protect the right to health care and well-being of ageing prisoners. Additionally, it is important to design legal structures and guidelines which acknowledge and accommodate the needs of ageing prisoners.

Intrauterine exposure to carbamazepine and specific congenital malformations: systematic review and case-control study.

OBJECTIVE: To identify specific major congenital malformations associated with use of carbamazepine in the first trimester of pregnancy. DESIGN: A review of all published cohort studies to identify key indications and a population based case-control study to test these indications. SETTING: Review of PubMed, Web of Science, and Embase for papers about carbamazepine exposure in the first trimester of pregnancy and specific malformations, and the EUROCAT Antiepileptic Study Database, including data from 19 European population based congenital anomaly registries, 1995-2005. PARTICIPANTS: The literature review covered eight cohort studies of 2680 pregnancies with carbamazepine monotherapy exposure, and the EUROCAT dataset included 98 075 registrations of malformations covering over 3.8 million births. MAIN OUTCOME MEASURES: Overall prevalence for a major congenital malformation after exposure to carbamazepine monotherapy in the first trimester. Odds ratios for malformations with exposure to carbamazepine among cases (five types of malformation identified in the literature review) compared with two groups of controls: other non-chromosomal registrations of malformations and chromosomal syndromes. RESULTS: The literature review yielded an overall prevalence for a major congenital malformation of 3.3% (95% confidence interval 2.7 to 4.2) after exposure to carbamazepine monotherapy in the first trimester. In 131 registrations of malformations, the fetus had been exposed to carbamazepine monotherapy. Spina bifida was the only specific major congenital malformation significantly associated with exposure to carbamazepine monotherapy (odds ratio 2.6 (95% confidence interval 1.2 to 5.3) compared with no antiepileptic drug), but the risk was smaller for carbamazepine than for valproic acid (0.2, 0.1 to 0.6). There was no evidence for an association with total anomalous pulmonary venous return (no cases with carbamazepine exposure), cleft lip (with or without palate) (0.2, 0.0 to 1.3), diaphragmatic hernia (0.9, 0.1 to 6.6), or hypospadias (0.7, 0.3 to 1.6) compared with no exposure to antiepileptic drugs. Further exploratory analysis suggested a higher risk of single ventricle and atrioventricular septal defect. CONCLUSION: Carbamazepine teratogenicity is relatively specific to spina bifida, though the risk is less than with valproic acid. Despite the large dataset, there was not enough power to detect moderate risks for some rare major congenital malformations.

Supervised injection services : what has been demonstrated? : a systematic literature review

BACKGROUND: Supervised injection services (SISs) have been developed to promote safer drug injection practices, enhance health-related behaviors among people who inject drugs (PWID), and connect PWID with external health and social services. Nevertheless, SISs have also been accused of fostering drug use and drug trafficking. AIMS: To systematically collect and synthesize the currently available evidence regarding SIS-induced benefits and harm. METHODS: A systematic review was performed via the PubMed, Web of Science, and ScienceDirect databases using the keyword algorithm [("SUPERVISED" OR "SAFER") AND ("INJECTION" OR "INJECTING" OR "SHOOTING" OR "CONSUMPTION") AND ("FACILITY" OR "FACILITIES" OR "ROOM" OR "GALLERY" OR "CENTRE" OR "SITE")]. RESULTS: Seventy-five relevant articles were found. All studies converged to find that SISs were efficacious in attracting the most marginalized PWID, promoting safer injection conditions, enhancing access to primary health care, and reducing the overdose frequency. SISs were not found to increase drug injecting, drug trafficking or crime in the surrounding environments. SISs were found to be associated with reduced levels of public drug injections and dropped syringes. Of the articles, 85% originated from Vancouver or Sydney. CONCLUSION: SISs have largely fulfilled their initial objectives without enhancing drug use or drug trafficking. Almost all of the studies found in this review were performed in Canada or Australia, whereas the majority of SISs are located in Europe. The implementation of new SISs in places with high rates of injection drug use and associated harms appears to be supported by evidence.

Atuação do enfermeiro no manejo da incontinência urinária no idoso: uma revisão integrativa

Este estudo teve como objetivo verificar quais são as estratégias utilizados pelos enfermeiros para o manejo da incontinência urinária (IU) em idosos. Realizou-se um estudo de revisão integrativa da literatura nas seguintes bases de dados: WEB OF SCIENCE, MEDLINE, SCOPUS e CINAHL, no período de 2006 a 2010. Foram encontradas 186 publicações, e, após a exclusão daquelas com duplicidade e a leitura cuidadosa dos trabalhos na íntegra, a amostra constituiu-se de sete artigos. A maior parte das pesquisas aborda a incontinência urinária de uma maneira geral, sem caracterização quanto ao seu tipo ou queixas presentes nos sujeitos da pesquisa. Apenas um trabalho referia-se ao manejo de incontinência urinária em idosos com demência e outro especificou o tipo (bexiga hiperativa). Diante disso, destaca-se a necessidade de realizar pesquisas clínicas sobre o manejo da incontinência urinária realizado por enfermeiros, visando o fornecimento de evidências científicas para o embasamento dessa prática.

Práticas baseadas em evidências publicadas no Brasil: identificação e reflexão na área da prevenção em saúde humana

Revisão integrativa de estudos brasileiros sobre práticas baseadas em evidências (PBE) acerca da prevenção em saúde humana, publicados em periódicos Web of Science/JCR, de outubro de 2010 a abril de 2011. O objetivo foi identificar as especialidades que mais realizaram estes estudos, seus enfoques e abordagens metodológicas. A partir de critérios de inclusão, foram selecionados 84 trabalhos publicados majoritariamente em periódicos de saúde pública, focalizando a atenção primária e abrangendo também questões clínicas e diversas especialidades. Variaram também os enfoques de prevenção e as abordagens metodológicas, predominando a revisão sistemática sem metanálise. Os resultados indicam que não há uma única maneira de conceituar e praticar a PBE na prevenção e sua aplicação pode não ser apenas para obtenção de prova irrefutável para instrumentalizar ações de intervenção. Constitui um campo infindável de conhecimentos, em construção, para análise e maior compreensão de fenômenos em saúde.

Risk factors for falls in hospitalized adult patients: an integrative review

Objective: Identifying risk factors for the occurrence of falls in hospitalized adult patients. Method: Integrative review carried out in the databases of LILACS, SciELO, MEDLINE and Web of Science, including articles published between 1989 and 2012. Results: Seventy-one articles were included in the final sample. Risk factors for falls presented in this review were related to patients (intrinsic), the hospital setting and the working process of health professionals, especially in nursing (extrinsic). Conclusion: The systematic screening of risk factors for falls was identified as a contributing factor to the reduction of this injury, helping the non-occurrence of this event that, despite being preventable, can have serious consequences including death.

Organización de la reanimación cardiopulmonar intrahospitalaria. Situación actual en España.

La parada cardiorrespiratoria (PCR) dentro del hospital es considerada una emergencia vital y está demostrado que existe una relación directa entre la respuesta asistencial y la mortalidad asociada a este evento. Los resultados del tratamiento de la PCR son un indicador de calidad de los centros sanitarios. En el caso en concreto de España, la mayoría de hospitales no disponen de un sistema organizado e integral de atención a la PCR. A pesar de los avances en medicina y tecnológicos, la tasa de supervivencia no ha variado significativamente en los últimos 30 años por lo que se ha de considerar como un problema social, económico y sanitario de gran magnitud que cabe abordar con todas las herramientas disponibles. Objetivos: Conocer cómo se organiza la reanimación cardiopulmonar (RCP) dentro del hospital y conocer los planes integrales de RCP publicados por los hospitales españoles. Metodología: Se realiza una revisión de la literatura a través de las bibliotecas indexadas Pubmed y Web of Science mediante criterios de inclusión/exclusión, uso de operadores booleanos y búsqueda bibliográfica manual. Además se realiza una entrevista a un médico referente nacional en la investigación sobre RCP. Resultados: Se han encontrado 7 planes integrales para la atención a la PCR y solo 2 de ellos están avalados por el Plan Nacional de RCP (PNRCP), miembro del Consejo Español de RCP (CERCP). Conclusiones: Existe una falta de publicaciones por parte de los hospitales españoles sobre planes integrales para la organización de la RCP que cumplan los criterios de calidad necesarios. Si bien todos los hospitales disponen de protocolos propios dirigidos a sus profesionales para la actuación en caso de PCR, estos son de uso interno y solo tienen en común entre ellos el hecho de seguir las recomendaciones de las guías del European Resuscitation Council (ERC). III Es necesario que los centros sanitarios fomenten y compartan su actividad investigadora sobre el tema. Palabras clave: parada cardíaca hospitalaria, resucitación cardiopulmonar, Plan hospitalario de resucitación.
