Aromatherapy for treatment of postoperative nausea and vomiting

Background: Postoperative nausea and vomiting is a common and unpleasant phenomenon and current therapies are not always effective for all patients. Aromatherapy has been suggested as a possible addition to the available treatment strategies. Objectives: This review sought to establish what effect the use of aromatherapy has on the severity and duration of established postoperative nausea and vomiting and whether aromatherapy can be used with safety and clinical effectiveness comparable to standard pharmacological treatments. Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3); MEDLINE; EMBASE; CINAHL; CAM on PubMed; Meditext; LILACS database; and ISI Web of Science as well as grey literature sources and the reference lists of retrieved articles. We conducted database searches up to August 2011. Selection criteria: We included all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) where aromatherapy was used to treat postoperative nausea and vomiting. Interventions were all types of aromatherapy. Aromatherapy was defined as the inhalation of the vapours of any substance for the purposes of a therapeutic benefit. Primary outcomes were the severity and duration of postoperative nausea and vomiting. Secondary outcomes were adverse reactions, use of rescue anti-emetics and patient satisfaction with treatment. Data collection and analysis: Two review authors assessed risk of bias in the included studies and extracted data. As all outcomes analysed were dichotomous, we used a fixed-effects model and calculated relative risk (RR) with associated 95% confidence interval (95% CI). Results: The nine included studies comprised six RCTs and three CCTs with a total of 402 participants. The mean age and range data for all participants were not reported for all studies. The method of randomization in four of the six included RCTs was explicitly stated and adequate. Incomplete reporting of data affected the completeness of the analysis. Compared with placebo, isopropyl alcohol vapour inhalation was effective in reducing the proportion of participants requiring rescue anti-emetics (RR 0.30, 95%CI 0.09 to 1.00, P = 0.05). However, compared with standard anti-emetic treatment, isopropyl alcohol was not effective in reducing the proportion of participants requiring rescue anti-emetics (RR 0.66 95%CI 0.39 to 1.13, P = 0.13) except when the data from a possibly confounded study were included (RR 0.66, 95% CI 0.45 to 0.98, P = 0.04). Where studies reported data on patient satisfaction with aromatherapy, there were no statistically significant differences between the groups (RR 1.12, 95%CI 0.62 to 2.03, P = 0.71). Authors' conclusions: Isopropyl alcohol was more effective than saline placebo for reducing postoperative nausea and vomiting but less effective than standard anti-emetic drugs. There is currently no reliable evidence for the use of peppermint oil.

Prevention and treatment of acute radiation-induced skin reactions : a systematic review and meta-analysis of randomized controlled trials

Background Radiation-induced skin reaction (RISR) is a common side effect that affects the majority of cancer patients receiving radiation treatment. RISR is often characterised by swelling,redness, pigmentation, fibrosis, and ulceration, pain, warmth, burning, and itching of the skin. The aim of this systematic review was to assess the effects of interventions which aim to prevent or manage RISR in people with cancer. Methods We searched the following databases up to November 2012: Cochrane Skin Group Specialised Register, CENTRAL (2012, Issue 11), MEDLINE (from 1946), EMBASE (from 1974), PsycINFO (from 1806), CINAHL (from 1981) and LILACS (from 1982). Randomized controlled trials evaluating interventions for preventing or managing RISR in cancer patients were included. The primary outcomes were development of RISR, and levels of RISR and symptom severity. Secondary outcomes were time taken to develop erythema or dry desquamation; quality of life; time taken to heal, a number of skin reaction and symptom severity measures; cost, participant satisfaction; ease of use and adverse effects. Where appropriate, we pooled results of randomized controlled trials using mean differences (MD) or odd ratios (OR) with 95% confidence intervals (CI). Results Forty-seven studies were included in this review. These evaluated six types of interventions (oral systemic medications; skin care practices; steroidal topical therapies; non-steroidal topical therapies; dressings and other). Findings from two meta-analyses demonstrated significant benefits of oral Wobe-Mugos E for preventing RISR (OR 0.13 (95% CI 0.05 to 0.38)) and limiting the maximal level of RISR (MD −0.92 (95% CI −1.36 to −0.48)). Another meta-analysis reported that wearing deodorant does not influence the development of RISR (OR 0.80 (95% CI 0.47 to 1.37)). Conclusions Despite the high number of trials in this area, there is limited good, comparative research that provides definitive results suggesting the effectiveness of any single intervention for reducing RISR. More research is required to demonstrate the usefulness of a wide range of products that are being used for reducing RISR. Future efforts for reducing RISR severity should focus on promising interventions, such as Wobe-Mugos E and oral zinc.

A systematic review of community-based interventions for emerging zoonotic diseases in Southeast Asia

Background Southeast Asia has been at the epicentre of recent epidemics of emerging and re-emerging zoonotic diseases. Community-based surveillance and control interventions have been heavily promoted but the most effective interventions have not been identified. Objectives This review evaluated evidence for the effectiveness of community-based surveillance interventions at monitoring and identifying emerging infectious disease; the effectiveness of community-based control interventions at reducing rates of emerging infectious disease; and contextual factors that influence intervention effectiveness. Inclusion criteria Participants Communities in Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Viet Nam. Types of intervention(s) Non-pharmaceutical, non-vaccine, and community-based surveillance or prevention and control interventions targeting rabies, Nipah virus , dengue, SARS or avian influenza. Types of outcomes Primary outcomes: measures: of infection or disease; secondary outcomes: measures of intervention function. Types of studies Original quantitative studies published in English. Search strategy Databases searched (1980 to 2011): PubMed, CINAHL, ProQuest, EBSCOhost, Web of Science, Science Direct, Cochrane database of systematic reviews, WHOLIS, British Development Library, LILACS, World Bank (East Asia), Asian Development Bank. Methodological quality Two independent reviewers critically appraised studies using standard Joanna Briggs Institute instruments. Disagreements were resolved through discussion. Data extraction A customised tool was used to extract quantitative data on intervention(s), populations, study methods, and primary and secondary outcomes; and qualitative contextual information or narrative evidence about interventions. Data synthesis Data was synthesised in a narrative summary with the aid of tables. Meta-analysis was used to statistically pool quantitative results. Results Fifty-seven studies were included. Vector control interventions using copepods, environmental cleanup and education are effective and sustainable at reducing dengue in rural and urban communities, whilst insecticide spraying is effective in urban outbreak situations. Community-based surveillance interventions can effectively identify avian influenza in backyard flocks, but have not been broadly applied. Outbreak control interventions for Nipah virus and SARS are effective but may not be suitable for ongoing control. Canine vaccination and education is more acceptable than culling, but still fails to reach coverage levels required to effectively control rabies. Contextual factors were identified that influence community engagement with, and ultimately effectiveness of, interventions. Conclusion Despite investment in community-based disease control and surveillance in Southeast Asia, published evidence evaluating interventions is limited in quantity and quality. Nonetheless this review identified a number of effective interventions, and several contextual factors influencing effectiveness. Identification of the best programs will require comparative evidence of effectiveness acceptability, cost-effectiveness and sustainability.

Community wide interventions for increasing physical activity

Background Multi-strategic community wide interventions for physical activity are increasingly popular but their ability to achieve population level improvements is unknown. Objectives To evaluate the effects of community wide, multi-strategic interventions upon population levels of physical activity. Search methods We searched the Cochrane Public Health Group Segment of the Cochrane Register of Studies,The Cochrane Library, MEDLINE, MEDLINE in Process, EMBASE, CINAHL, LILACS, PsycINFO, ASSIA, the British Nursing Index, Chinese CNKI databases, EPPI Centre (DoPHER, TRoPHI), ERIC, HMIC, Sociological Abstracts, SPORTDiscus, Transport Database and Web of Science (Science Citation Index, Social Sciences Citation Index, Conference Proceedings Citation Index). We also scanned websites of the EU Platform on Diet, Physical Activity and Health; Health-Evidence.org; the International Union for Health Promotion and Education; the NIHR Coordinating Centre for Health Technology (NCCHTA); the US Centre for Disease Control and Prevention (CDC) and NICE and SIGN guidelines. Reference lists of all relevant systematic reviews, guidelines and primary studies were searched and we contacted experts in the field. The searches were updated to 16 January 2014, unrestricted by language or publication status. Selection criteria Cluster randomised controlled trials, randomised controlled trials, quasi-experimental designs which used a control population for comparison, interrupted time-series studies, and prospective controlled cohort studies were included. Only studies with a minimum six-month follow up from the start of the intervention to measurement of outcomes were included. Community wide interventions had to comprise at least two broad strategies aimed at physical activity for the whole population. Studies which randomised individuals from the same community were excluded. Data collection and analysis At least two review authors independently extracted the data and assessed the risk of bias. Each study was assessed for the setting, the number of included components and their intensity. The primary outcome measures were grouped according to whether they were dichotomous (per cent physically active, per cent physically active during leisure time, and per cent physically inactive) or continuous (leisure time physical activity time (time spent)), walking (time spent), energy expenditure (as metabolic equivalents or METS)). For dichotomous measures we calculated the unadjusted and adjusted risk difference, and the unadjusted and adjusted relative risk. For continuous measures we calculated percentage change from baseline, unadjusted and adjusted. Main results After the selection process had been completed, 33 studies were included. A total of 267 communities were included in the review (populations between 500 and 1.9 million). Of the included studies, 25 were set in high income countries and eight were in low income countries. The interventions varied by the number of strategies included and their intensity. Almost all of the interventions included a component of building partnerships with local governments or non-governmental organisations (NGOs) (29 studies). None of the studies provided results by socio-economic disadvantage or other markers of equity. However, of those included studies undertaken in high income countries, 14 studies were described as being provided to deprived, disadvantaged or low socio-economic communities. Nineteen studies were identified as having a high risk of bias, 10 studies were unclear, and four studies had a low risk of bias. Selection bias was a major concern with these studies, with only five studies using randomisation to allocate communities. Four studies were judged as being at low risk of selection bias although 19 studies were considered to have an unclear risk of bias. Twelve studies had a high risk of detection bias, 13 an unclear risk and four a low risk of bias. Generally, the better designed studies showed no improvement in the primary outcome measure of physical activity at a population level. All four of the newly included, and judged to be at low risk of bias, studies (conducted in Japan, United Kingdom and USA) used randomisation to allocate the intervention to the communities. Three studies used a cluster randomised design and one study used a stepped wedge design. The approach to measuring the primary outcome of physical activity was better in these four studies than in many of the earlier studies. One study obtained objective population representative measurements of physical activity by accelerometers, while the remaining three low-risk studies used validated self-reported measures. The study using accelerometry, conducted in low income, high crime communities of USA, emphasised social marketing, partnership with police and environmental improvements. No change in the seven-day average daily minutes of moderate to vigorous physical activity was observed during the two years of operation. Some program level effect was observed with more people walking in the intervention community, however this result was not evident in the whole community. Similarly, the two studies conducted in the United Kingdom (one in rural villages and the other in urban London; both using communication, partnership and environmental strategies) found no improvement in the mean levels of energy expenditure per person per week, measured from one to four years from baseline. None of the three low risk studies reporting a dichotomous outcome of physical activity found improvements associated with the intervention. Overall, there was a noticeable absence of reporting of benefit in physical activity for community wide interventions in the included studies. However, as a group, the interventions undertaken in China appeared to have the greatest possibility of success with high participation rates reported. Reporting bias was evident with two studies failing to report physical activity measured at follow up. No adverse events were reported.The data pertaining to cost and sustainability of the interventions were limited and varied. Authors' conclusions Although numerous studies have been undertaken, there is a noticeable inconsistency of the findings in the available studies and this is confounded by serious methodological issues within the included studies. The body of evidence in this review does not support the hypothesis that the multi-component community wide interventions studied effectively increased physical activity for the population, although some studies with environmental components observed more people walking. Plain language summary Community wide interventions for increasing physical activity Not having enough physical activity leads to poorer health. Regular physical activity can reduce the risk of chronic disease and improve one's health and wellbeing. The lack of physical activity is a common and in some cases a growing health problem. To address this, 33 studies have used improvement activities directed at communities, using more than one approach in a single program. When we first looked at the available research in 2011 we observed that there was a lack of good studies which could show whether this approach was beneficial or not. Some studies claimed that community wide programs improved physical activities and other studies did not. In this update we found four new studies that were of good quality; however none of these four studies increased physical activity levels for the population. Some studies reported program level effects such as observing more people walking, however the population level of physical activity had not increased. This review found that community wide interventions are very difficult to undertake, and it appears that they usually fail to provide a measurable benefit in physical activity for a population. It is apparent that many of the interventions failed to reach a substantial portion of the community, and we speculate that some single strategies included in the combination may lack individual effectiveness. Laički sažetak Intervencije u zajednici za povećanje tjelesne aktivnosti Nedostatna tjelesna aktivnost povezana je s lošijim zdravljem.Redovita tjelesna aktivnost može umanjiti rizik od kroničnih bolesti te poboljšati zdravlje i kvalitetu života pojedinca.Manjak tjelesne aktivnosti čest je problem, a učestalost tog problema se povećava.Cochrane sustavni pregled je analizirao 33 studije koje su istražile programe za povećanje tjelesne aktivnosti u zajednici, u kojima se koristilo više od jednog pristupa.Kad su prvi put pregledani dokazi iz istraživanja koja su bila dostupna 2011. godine, utvrđeno je da nema dovoljno dobrih studija koje bi mogle pokazati je li takav pristup koristan ili ne.Primjerice, neke studije tvrde da programi za povećanje tjelesne aktivnosti u zajednici poboljšavaju tjelesnu aktivnost pojedinaca u zajednici, a druge studije tvrde suprotno.U ovom obnovljenom sustavnom pregledu pronađene su 4 nove studije koje su bile visoke kvalitete, ail nijedna od tih studija nije pokazala da je istraživana intervencija dovela do povećanja tjelesne aktivnosti u zajednici.Neke su studije opisale učinak na način da je opisano da je uočeno da više ljudi u zajednici hoda, međutim, ukupna razina tjelesne aktivnosti u promatranoj populaciji nije se povećala.Ovaj sustavni pregled je utvrdio da je intervencije za povećanje tjelesne aktivnosti u zajednici teško provesti i čini se da one obično ne uspijevaju u svojoj namjeri da na mjerljiv način povećaju tjelesnu aktivnost u populaciji.Čini se da mnoge intervencije nisu uspjele doseći veći broj stanovnika u zajednici pa se može smatrati da neke od strategija uključene u analizirane kombinacije nisu zasebno učinkovite.

Intensive versus conventional glycaemic control for treating diabetic foot ulcers

Background The estimated likelihood of lower limb amputation is 10 to 30 times higher amongst people with diabetes compared to those without diabetes. Of all non-traumatic amputations in people with diabetes, 85% are preceded by a foot ulcer. Foot ulceration associated with diabetes (diabetic foot ulcers) is caused by the interplay of several factors, most notably diabetic peripheral neuropathy (DPN), peripheral arterial disease (PAD) and changes in foot structure. These factors have been linked to chronic hyperglycaemia (high levels of glucose in the blood) and the altered metabolic state of diabetes. Control of hyperglycaemia may be important in the healing of ulcers. Objectives To assess the effects of intensive glycaemic control compared to conventional control on the outcome of foot ulcers in people with type 1 and type 2 diabetes. Search methods In December 2015 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; EBSCO CINAHL; Elsevier SCOPUS; ISI Web of Knowledge Web of Science; BioMed Central and LILACS. We also searched clinical trial databases, pharmaceutical trial databases and current international and national clinical guidelines on diabetes foot management for relevant published, non-published, ongoing and terminated clinical trials. There were no restrictions based on language or date of publication or study setting. Selection criteria Published, unpublished and ongoing randomised controlled trials (RCTs) were considered for inclusion where they investigated the effects of intensive glycaemic control on the outcome of active foot ulcers in people with diabetes. Non randomised and quasi-randomised trials were excluded. In order to be included the trial had to have: 1) attempted to maintain or control blood glucose levels and measured changes in markers of glycaemic control (HbA1c or fasting, random, mean, home capillary or urine glucose), and 2) documented the effect of these interventions on active foot ulcer outcomes. Glycaemic interventions included subcutaneous insulin administration, continuous insulin infusion, oral anti-diabetes agents, lifestyle interventions or a combination of these interventions. The definition of the interventional (intensive) group was that it should have a lower glycaemic target than the comparison (conventional) group. Data collection and analysis All review authors independently evaluated the papers identified by the search strategy against the inclusion criteria. Two review authors then independently reviewed all potential full-text articles and trials registry results for inclusion. Main results We only identified one trial that met the inclusion criteria but this trial did not have any results so we could not perform the planned subgroup and sensitivity analyses in the absence of data. Two ongoing trials were identified which may provide data for analyses in a later version of this review. The completion date of these trials is currently unknown. Authors' conclusions The current review failed to find any completed randomised clinical trials with results. Therefore we are unable to conclude whether intensive glycaemic control when compared to conventional glycaemic control has a positive or detrimental effect on the treatment of foot ulcers in people with diabetes. Previous evidence has however highlighted a reduction in risk of limb amputation (from various causes) in people with type 2 diabetes with intensive glycaemic control. Whether this applies to people with foot ulcers in particular is unknown. The exact role that intensive glycaemic control has in treating foot ulcers in multidisciplinary care (alongside other interventions targeted at treating foot ulcers) requires further investigation.

Sireenit, floksit ja iirikset- Puu-Käpylän koristekasvit

Puu-Käpylä (“Wooden Käpylä”), a neighbourhood of Helsinki, is the earliest example of the Garden City Movement in Finland. The suburb of valuable wooden architecture was built between 1920 and 1925, with the aim to provide a healthy housing area for working-class families with many children. The houses were erected by a co-operative (Käpylän kansanasunnot, “People?s Dwellings”) and they are protected by the city plan since 1960?s. However, the historical value of the sheltered courtyards has not been investigated. The aim of this study was to survey the garden flora of Puu-Käpylä and to evaluate the authenticity of the courtyard gardens. The survey covered the area of one residential quarter (1.2 ha) with twelve 2-storey semi-detached timber houses arranged around a common yard, which was originally appointed for the tenants? vegetable gardens. The houses are still rented, and each flat is allowed a small lot of the courtyard for cultivation. A complete list was made of all perennial, ornamental plant taxa present in the quarter. Spring bulbs were missed due to the timing of the survey. Generally, the plants were recorded on species level, with the exception of common lilacs, shrub roses, irises and peonies that were thoroughly studied for cultivar identification. It was assumed that plants initially grown in the courtyard could be distinguished by studying Finnish garden magazines, books and nursery catalogues published in the 1920?s and by comparing the present vegetation to surviving documents from the quarter. The total number of ornamental plant taxa identified was 172, of which 17 were trees, 47 shrubs, 7 climbers and 101 herbaceous perennials. The results indicated that a major part of the shrubs, climbers and perennials presumably originated from the 1970?s or later, whereas ca. 70 % of the tree specimens were deemed as original. The survey disclosed a heritage variety of common lilac, resembling cultivar „Prince Notger?, a specific peony taxon, Paeonia humilis Retz., cultivated in Nordic countries since long ago, and a few historic iris varieties. Well-preserved design elements included front gardens on one side of the quarter, a maple alley on another side as well as trees at the garden gates. Old garden books and magazines did not shed much light on the Finnish garden flora commonly used in the period when Puu-Käpylä was built. However, they gave a valuable picture of contemporary planting design. Nursery catalogues offered insight into the assortment of ornamental plants traded in the 1920?s. Conclusions on the authenticity of the current flora were mainly drawn on the basis of old photographs and a vegetation survey map drawn in the 1970?s. This study revealed a need for standardization of syrvey methods applied when investigating garden floras. Uniform survey techniques would make the results comparable and enable a future compilation of data from e.g. historic gardens.

PUVA X catarata : revisão sistemática da literatura

A fim de se encontrar as evidências sobre a ocorrência de catarata em pacientes submetidos a PUVA terapia, realizou-se uma revisão sistemática da literatura publicada, utilizando-se as bases de dados MEDLINE, LILACS, Cochrane Library, Excerpta Medica e o programa MICROMEDEX. Foram elaboradas estratégias de busca para cada base de dados. Após aplicação dos critérios de seleção definidos, incluíram-se 30 artigos que representavam 21 estudos que abordavam o tema. Os dados de cada estudo foram recolhidos a partir de um formulário de coleta criado para este fim. A avaliação da qualidade dos estudos se deu por classificação das evidências em categorias e posterior relação destas categorias com a força de recomendação das evidências para a prática clínica, de acordo com critérios previamente publicados. Ainda, elaborou-se um esquema de classificação de qualidade específico para os estudos incluídos. Realizou-se análise estatística dos dados apresentados através de análise de sobrevida, utilizando-se o modelo de Cox de hazards proporcionais. As evidências publicadas das bases de dados, capturadas pelas estratégias de busca e selecionadas pelos critérios de inclusão e exclusão não são suficientes para se afirmar se a catarata pode ou não ser uma reação adversa a PUVA terapia. Não foi possível, também, encontrar um modelo matemático que pudesse indicar relação entre as variáveis explicativas e a função de hazards.

Avaliações econômicas do uso da vacina contra o Papilomavírus Humano (HPV) em meninas adolescentes: uma revisão sistemática

O câncer de colo do útero persiste como um importante problema de saúde em todo o mundo, em particular nos países em desenvolvimento. Duas vacinas contra o papilomavirus humano (HPV) encontram-se atualmente disponíveis e aprovadas para uso em meninas adolescentes, antes do início da vida sexual: uma bivalente, contra os sorotipos 16 e 18 e outra quadrivalente, contra os sorotipos 6, 11, 16 e 18. Estes imunobiológicos têm por objetivo induzir uma imunidade contra o papilomavírus e, desta forma, atuar na prevenção primária do câncer do colo de útero. As avaliações econômicas podem ser um elemento que auxiliem nos processos de tomada de decisão sobre a incorporação da vacina em programas de imunização nacionais. Estas avaliações foram o objeto central deste trabalho, que teve como objetivo sintetizar as evidências procedentes de uma revisão sistemática da literatura de estudos de avaliação econômica da utilização da vacina contra o HPV em meninas adolescentes e pré-adolescentes. Foi realizada uma busca na literatura nas bases MEDLINE (via Pubmed), LILACS (via Bireme) e National Health Service Economic Evaluation Database (NHS EED) ate junho de 2010. Dois avaliadores, de forma independente, selecionaram estudos de avaliação econômica completa, que tivessem como foco a imunização para HPV em mulheres com as vacinas comercialmente disponíveis direcionada à população adolescente. Após a busca, 188 títulos foram identificados; destes, 39 estudos preencheram os critérios de elegibilidade e foram incluídos na revisão. Por tratar-se de uma revisão de avaliações econômicas, não foi realizada uma medida de síntese dos valores de relação incremental entre custos e efetividade. Os 39 artigos incluídos envolveram 51 avaliações econômicas em 26 países. Predominaram estudos de custo-utilidade (51%). Do ponto de vista da perspectiva da análise, predominou o dos sistemas de saúde (76,4%). A maioria dos trabalhos (94,9%) elegeu meninas, com idade entre 9 e 12 anos, como sua população alvo e desenvolveu simulações considerando imunidade para toda a vida (84,6%). Os modelos utilizados nos estudos foram do tipo Markov em 25 análises, de transmissão dinâmica em 11 e híbridos em 3. As análises de sensibilidade revelaram um conjunto de elementos de incerteza, uma parte significativa dos quais relacionados a aspectos vacinais: custos da vacina, duração da imunidade, necessidade de doses de reforço, eficácia vacinal e cobertura do programa. Estes elementos configuram uma área de especial atenção para futuros modelos que venham a ser desenvolvidos no Brasil para análises econômicas da vacinação contra o HPV.

Doença periodontal é fator de risco para parto prematuro e bebê de baixo peso?: revisão sistemática

O objetivo desta revisão sistemática foi analisar os estudos que relacionam doença periodontal e nascimento prematuro e baixo peso, verificando o efeito da doença periodontal materna no desfecho da gestação. Foi realizada pesquisa nas seguintes bases de dados: PubMed, Scielo e LILACS até Dezembro de 2007. A revisão sistemática foi conduzida de forma a identificar os estudos capazes de preencher os critérios de inclusão, apresentando aspectos clínicos, microbiológicos e radiográficos da doença periodontal, assim como os desfechos da gestação, ou seja, nascimento prematuro e baixo peso. Foram então selecionados 35 (trinta e cinco) artigos, sendo 9 (nove) coorte, 16 (dezesseis) casos controles, e 10 (dez) ensaios clínicos. A associação entre a doença periodontal materna e o nascimento de bebê prematuro com baixo peso foi encontrada em 26 (vinte e seis) estudos: 7 (sete) coorte, 11 (onze) casos controles e 8 (oito) ensaios clínicos. Não foi possível realizar uma meta-análise devido à grande heterogeneidade entre os estudos, particularmente no que se refere aos métodos de mensuração da doença periodontal. Um melhor controle em relação aos fatores de confusão também permitiria uma confiança maior nos resultados e conclusões apresentadas. Ainda não é possível ter conclusões adequadas do real efeito da doença periodontal sobre os desfechos da gestação devido a limitações nas metodologias dos presentes estudos. Portanto, a evidência da relação da doença periodontal com o nascimento de bebê prematuro e baixo peso é limitada. Ainda existe a necessidade de novos e bem desenhados estudos observacionais e de intervenção, que possam confirmar o que até agora é visto apenas como uma possível associação, explorando a validade dessas possíveis associações em diferentes populações e controlando adequadamente as variáveis de confusão.

Associação entre o nível de escolaridade e a idade da menopausa: uma revisão sistemática

O século XX foi marcado por significativa transformação social, que se refletiu em rápido aumento da expectativa de vida da população mundial. Nesse contexto, é cada vez mais significativa a parcela de mulheres que atingem a menopausa. Doenças cardiovasculares, que representam a principal causa de morte entre os adultos, e a osteoporose, apresentam uma relação nítida com a antecipação da menopausa, isto é, aquela que ocorre abaixo da média esperada para uma população. As pesquisas na área, antes praticamente relacionadas ao tratamento dos efeitos causados pelo climatério, se voltam cada vez mais para entender como os hábitos ou estilos de vida podem influenciar a fisiologia ovariana e, conseqüentemente, alterar o momento da menopausa. A relação com alguns destes hábitos, como o fumo, já apresenta forte embasamento na literatura. Entretanto, a correlação com o nível socioeconômico, seja pelas dificuldades de se medir adequadamente esse constructo, ou talvez pela quantidade insuficiente de trabalhos de qualidade, não se apresenta de forma tão evidente. O nível de escolaridade, considerado um dos melhores indicadores do nível socioeconômico, tanto pela maior facilidade de obtenção da informação, como pelo já demonstrado grau de associação com diversos desfechos em saúde, foi avaliado nesta revisão sistemática como fator de exposição para a antecipação da idade da menopausa. Este trabalho se alinha com a crescente tendência de se entender como os determinantes sociais podem influenciar nos desfechos em saúde, e de se buscar estratégias eficazes em prol da diminuição das desigualdades em saúde. A estratégia de busca eletrônica foi desenvolvida de forma específica para as diferentes bases (MEDLINE [PubMed] e LILACS) e através de consulta a referências cruzadas. Somente foram incluídos estudos observacionais pela natureza da questão, já que não seria possível, neste caso, a realização de estudos experimentais. Após a identificação inicial de 776 artigos, 40 deles foram selecionados para apreciação do texto completo. No final, esta revisão sistemática englobou 30 artigos, relatando resultados de 32 estudos. Como resultado, verificou-se que estudos que não demonstram associação significativa do nível de educação com a idade da menopausa formaram a maioria da amostra. A forma como nível de escolaridade foi medida e a metodologia para comparação entre os estratos se mostraram largamente heterogêneas. Não se encontraram evidências inequívocas sobre a existência de associação entre o nível de escolaridade e a idade da menopausa através desta revisão.

Intervenções psicossociais para Transtornos Mentais Comuns na Atenção Primária à Saúde.

Os Transtornos Mentais Comuns (TMC), especialmente ansiedade e depressão, são altamente prevalentes, independentemente das dificuldades com a sua classificação. Na Atenção Primária à Saúde (APS), representada no Brasil pela Estratégia de Saúde da Família (ESF), essas condições são pouco detectadas e tratadas, o que resulta em sobrecarga para pacientes, famílias e comunidades, além de prejuízos sociais e econômicos. Tal situação pode ser atenuada integrando-se cuidados de saúde mental à atenção básica. Nesse sentido, objetivou-se identificar e analisar as intervenções psicossociais voltadas para o cuidado do sofrimento psíquico e dos TMC atualmente empregadas na APS, no Brasil e no exterior. Para isso, foi realizada uma revisão bibliográfica da literatura nacional e internacional através das bases de dados MEDLINE/PubMed e LILACS/BVS. As intervenções identificadas foram reunidas em dois grupos. No primeiro, incluíram-se as intervenções com formato tradicional em que um profissional graduado conduz o tratamento presencialmente, enquanto no segundo grupo foram alocados os arranjos diferenciados em que o contato com o profissional é reduzido e seu papel é mais o de facilitar do que de liderar o tratamento, tal como nas intervenções com o uso de mão de obra leiga em saúde, suporte ao autocuidado, e sistemas automatizados ou pacotes de tratamento informatizados oferecidos via internet. Teoricamente, Terapia Interpessoal, Terapia Cognitivo-comportamental e Terapia de Solução de Problemas embasaram as intervenções. Na APS internacional, as intervenções são breves e bastante estruturadas, incluindo um plano de ação definido em um manual de aplicação. Na Estratégia de Saúde da Família destacaram-se as intervenções grupais e a Terapia Comunitária, modelo especialmente desenvolvido por brasileiros. Verificou-se que os TMC ganham visibilidade à medida que a APS se consolida no território e próxima à população. No exterior, a integração da saúde mental na APS é um processo em consolidação e há crescente tecnificação das intervenções psicossociais, enquanto, no Brasil, a aproximação da APS com a ESF é recente e não há um padrão de atuação consolidado. Resultados insuficientes ou controversos impediram concluir quais são as melhores intervenções, porém a alta prevalência dos TMC e o potencial de cuidado do setor da APS exigem que as pesquisas continuem.
