Conhecimento de diferentes populações sobre as leishmanioses

As leishmanioses são enfermidades infecciosas que costumam afetar populações de países de clima tropical e subtropical, em sua maioria subdesenvolvidos, uma vez que seus principais vetores necessitam de condições ambientais e climáticas adequadas facilmente encontradas nessas regiões, para se proliferar. Há diferentes formas clínicas que se caracterizam por sua evolução crônica, sendo a forma visceral (LV) uma das mais graves. Neste caso, a disseminação é relativamente rápida uma vez que existe também a abundância de um dos seus principais reservatórios domésticos, o cão, que vive bem próximo ao homem, o qual é também acometido por esta zoonose. Dessa maneira é preciso que as populações, principalmente aquelas localizadas em áreas endêmicas, saibam identificar os pontos principais dessa doença como a transmissão, sinais clínicos e prevenção. Por esse motivo, essa revisão sistemática objetivou procurar saber qual o conhecimento de diferentes populações sobre as leishmanioses. Foram utilizados os seguintes descritores: (knowledge) AND (population) AND (leishmaniasis), através de um levantamento bibliográfico em três bases de dados, LILACS, SCIELO e PUBMED. Foi possível concluir, através da análise de sete artigos, que o conhecimento das leishmanioses ainda se encontra muito superficial dentro das populações e que a principal fonte de informação ainda é a informal, de pessoa a pessoa

Avaliação das alterações dentárias e esqueléticas induzidas pelo uso do aparelho de Herbst no tratamento da classe II na dentadura mista: Revisão sistemática

Objective: evaluate the immediate dental and skeletal changes induced by the Herbst appliance on early treatment of Angle´s Class II malocclusion. Material and Method: several electronic databases such as Scopus, Pub Med, Medline, Cochrane Library, Lilacs and Scielo were searched. The abstracts that fullfilled the selection criteria were selected and those that did not provide enough information about these criteria were selected but the final decision of including them or not on the research, was taken after the complete reading of the article. The selection criteria were: clinical studies with Class II individuals, both male and female, with initial age of 7 to 10 years, treated with the Herbst appliance that analysed the dental and/or skeletal changes evaluated on lateral cephalometric radiographs; researches where the treatment performed did not involve extractions or surgical interventions; studies that included patients without syndromes or health concerns and articles published in English or Portuguese. Results and Conclusions: five articles were selected. The articles showed that significant changes happened in the mandibular sagittal lenght, on facial convexity angle, on maxillo-mandibular relationship, on retroclination of the upper incisors and on distal movement of the upper molars, on proclination of the lower incisors and on extrusion of the lower molars. The appliance exerted a limited effect on the anterior relocation of the maxillary complex and on facial heights. However, more studies about the performance of the Herbst appliance on early treatment of Class II are needed.

Extensão universitária e trabalho voluntário na formação do acadêmico em odontologia

The aim of the present study was to point out the importance of the experience of undergraduate dental students in extra-curricular activities and volunteer work, as a means through which to gain essential knowledge and abilities for their professional lives. A literature review of the Medline, Scielo, and Lilacs databases was carried out in an attempt to select articles related to the university extension and volunteer work of undergraduate dental students. It is still extremely difficult to include university extension and volunteer work as an important activity in Dentistry courses. However, the presentday work market demands professionals who have expertise not only in dental techniques, but also in the socio-cultural characteristics of communities, considering that people need to be comprehensive in their psychosocial aspects in order to be treated as a complete professional. Therefore, university dentistry courses should give equal consideration to both oral rehabilitation skills and the promotion of general healthcare, acquired mainly through extracurricular activities, in an attempt to redeem the integral education of the healthcare professional. Moreover, students should pay closer attention to the opportunities offered during their undergraduate courses, as the work market for dentists is becoming more and more competitive. Moreover, the dentist whose professional life is limited to the dental office will most certainly forgo the opportunity to act in other social areas as well as the recognition that comes with such acts.

Tratamento biológico de fraturas ósseas com placa minimamente invasiva em pequenos animais: revisão sistemática

Objetivo: revisar sistematicamente a eficácia da técnica denominada osteossíntese com placa minimamente invasiva (MIPO), recentemente utilizada em medicina veterinária, em pequenos animais, em relação ao tempo de união óssea, alinhamento do membro e complicações no trans e pós-operatório. Material e Métodos: análise e comparação de artigos científicos retrospectivos e prospectivos sobre a técnica MIPO, publicados nas bases de dados informatizadas PUBMED, LILACS, Scielo e ScienceDirect. Resultados: foram selecionados cinco artigos adequados aos critérios de inclusão proposto, dois prospectivos e três retrospectivos, todos publicados nos últimos seis anos e em língua inglesa. Com esses trabalhos realizou-se uma discussão e conclusão a respeito da aplicação da MIPO em pequenos animais. Conclusão: A hipótese de que a MIPO é eficaz é aceita. A MIPO é uma técnica segura e sua aplicação em pequenos animais tem demonstrado resultados satisfatórios. Porém, com os estudos realizados até o momento não é possível afirmar que a aplicação da MIPO é estatisticamente mais eficaz que as técnicas convencionais quando aplicada em cães e gatos

Atenção Psicossocial e Psicologia: um mapeamento da produção científica

By the end of the 1970´s, begins the Psychiatric Reform Movement, whose development was the beginning of the construction of a new model, here termed Psychosocial Attention, to substitute the traditional psychiatric model. As such, aspires to be a process of paradigm shift and, therefore, requires transformations in the fields: theoretical-conceptual, technical-assistance, legal-political e sociocultural. This qualitative study composes a research which sought to ascertain the scientific production on the topic conducted by psychology, from the implementation of the Brazilian National Health System and the creation of new services to mental health care. In this sense, it proposed to investigate how the papers published in journals of psychology found in the database LILACS, since 1990, contribute to the process of building a new model that actually replace the so-called traditional psychiatric model.

Zinc supplementation for the prevention of type 2 diabetes mellitus in adults with insulin resistance

BackgroundDiabetes is associated with long-term damage, dysfunction and failure of various organs, especially the eyes, kidneys, nerves, heart and blood vessels. The risk of developing type 2 diabetes increases with age, obesity and lack of physical activity. Insulin resistance is a fundamental aspect of the aetiology of type 2 diabetes. Insulin resistance has been shown to be associated with atherosclerosis, dyslipidaemia, glucose intolerance, hyperuricaemia, hypertension and polycystic ovary syndrome. The mineral zinc plays a key role in the synthesis and action of insulin, both physiologically and in diabetes mellitus. Zinc seems to stimulate insulin action and insulin receptor tyrosine kinase activity.ObjectivesTo assess the effects of zinc supplementation for the prevention of type 2 diabetes mellitus in adults with insulin resistance.Search methodsThis review is an update of a previous Cochrane systematic review published in 2007. We searched the Cochrane Library (2015, Issue 3), MEDLINE, EMBASE, LILACS and the ICTRP trial register (frominception toMarch 2015). There were no language restrictions. We conducted citation searches and screened reference lists of included studies.Selection criteriaWe included studies if they had a randomised or quasi-randomised design and if they investigated zinc supplementation compared with placebo or no intervention in adults with insulin resistance living in the community.Data collection and analysisTwo review authors selected relevant trials, assessed risk of bias and extracted data.Main resultsWe included three trials with a total of 128 participants in this review. The duration of zinc supplementation ranged between four and 12 weeks. Risk of bias was unclear for most studies regarding selection bias (random sequence generation, allocation concealment) and detection bias (blinding of outcome assessment). No study reported on our key outcome measures (incidence of type 2 diabetes mellitus, adverse events, health-related quality of life, all-cause mortality, diabetic complications, socioeconomic effects). Evaluation of insulin resistance as measured by the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) showed neutral effects when comparing zinc supplementation with control (two trials; 114 participants). There were neutral effects for trials comparing zinc supplementation with placebo for total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol and triglycerides (2 studies, 70 participants). The one trial comparing zinc supplementation with exercise also showed neutral effects for total cholesterol, HDL and LDL cholesterol, and a mean difference in triglycerides of -30 mg/dL (95% confidence interval (CI) -49 to -10) in favour of zinc supplementation (53 participants). Various surrogate laboratory parameters were also analysed in the included trials.Authors'conclusionsThere is currently no evidence on which to base the use of zinc supplementation for the prevention of type 2 diabetes mellitus. Future trials should investigate patient-important outcome measures such as incidence of type 2 diabetes mellitus, health-related quality of life, diabetic complications, all-cause mortality and socioeconomic effects.

Do anticoagulant and antiplatelet agents prevent acute graft thrombosis in renal transplantation? A meta-analysis of case series studies

Introduction & Objectives: Thrombosis of the renal allograft is expected to occur in 1–6% of kidney transplants, and graft loss is expected in almost all cases. Anticoagulant and anti-platelet agents could serve as an adjunctive preventive measure, but sound evidence of benefits are still lacking, in this setting. We therefore assessed the efficacy and safety of anticoagulant and anti-platelet agents, in reducing the rate of renal allograft thrombosis. Methods: A review of the literature was carried out in major databases (MEDLINE, EMBASE and LILACS), with a comprehensive search strategy, to locate all available case series studies of anticoagulant and/or anti-platelet prophylaxis of thrombosis in renal transplantation. The date of the last search was 11 August 2014. We pooled all case series in a proportional meta-analysis. Statistical significance was achieved if the 95% confidence intervals obtained for each intervention did not overlap. Results: Our search strategy retrieved 7160 titles, from which 21 case series were chosen for analysis. A total of 3246 patients were identified (1718 treated with antiplatelet and/or anticoagulant agents, and 1528 non-treated control subjects). Allograft thrombosis occurred in 7.24% (95% CI 3.45 to 12.27%) of the patients receiving no intervention, compared to 3.38% (95% CI 1.45 to 6.1%), 1.2% (95% CI 0.6 to 2.1%) and 0.47% (95% CI 0.001 to 1.79%), in the anticoagulant, aspirin, and aspirin + anticoagulant groups, respectively. Bleeding complication rates were 28.0% (95% CI 15.4 to 42.7%) for anticoagulants, compared to 12.13% (95% CI 0.8 to 33.93%) for aspirin + anticoagulant, 0.31% (95% CI 0.0001 to 1.32%) for aspirin, and 6.1% (95% CI 2.2 to 11.7%) for the control group. Conclusions: Aspirin is more effective in reducing allograft thrombosis, after kidney transplantation, whether alone or in association with an anticoagulant, when compared to no drug prophylaxis, and without higher haemorrhagic complication rates. Anticoagulants, when used alone, do not show a beneficial effect on thrombosis rates, additionally yielding higher bleeding rates.

Outpatient versus inpatient treatment for acute pulmonary embolism

Background: Pulmonary embolism (PE) is a common life-threatening cardiovascular condition, with an incidence of 23 to 69 new cases per 100,000 people per year. Outpatient treatment instead of traditional inpatient treatment in selected non-high-risk patients with acute PE might provide several advantages, such as reduction of hospitalizations, substantial cost saving and an improvement in health-related quality of life. Objectives: To compare the efficacy and safety of outpatient versus inpatient treatment for acute PE for the outcomes of all-cause and PE-related mortality; bleeding; and adverse events such as hemodynamic instability, recurrence of PE and patients'satisfaction.Search methodsThe Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator (TSC) searched the Specialised Register (last searched October 2014) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 9). The TSC also searched clinical trials databases. The review authors searched LILACS (last searched November 2014). Selection criteria: Randomized controlled trials of outpatient versus inpatient treatment in people diagnosed with acute PE. Data collection and analysis: Two review authors selected relevant trials, assessed methodological quality, and extracted and analyzed data. Main results: We included one study, involving 339 participants. We ranked the quality of the evidence as very low due to not blinding the outcome assessors, the small number of events with imprecision in the confidential interval (CI), the small sample size and it was not possible to verify publication bias. For all outcomes, the CIs were wide and included clinically significant treatment effects in both directions: short-term mortality (30 days) (RR 0.33, 95% CI 0.01 to 7.98, P = 0.49), long-term mortality (90 days) (RR 0.98, 95% CI 0.06 to 15.58, P = 0.99), major bleeding at 14 days (RR 4.91, 95% CI 0.24 to 101.57, P = 0.30) and 90 days (RR 6.88, 95% CI 0.36 to 134.14, P = 0.20), recurrent PE within 90 days (RR 2.95, 95% CI 0.12 to 71.85, P = 0.51) and participant satisfaction (RR 0.97, 95% CI 0.92 to 1.03, P = 0.30). PE-related mortality, minor bleeding, and adverse course such as hemodynamic instability and compliance were not assessed by the single included study. Authors' conclusions: Current very low quality evidence from one published randomized controlled trial did not provide sufficient evidence to assess the efficacy and safety of outpatient versus inpatient treatment for acute PE in overall mortality, bleeding and recurrence of PE adequately. Further well-conducted research is required before informed practice decisions can be made.

Causes for the underreporting of adverse drug events by health professionals: a systematic review

Objective: Identifying the main causes for underreporting of Adverse Drug Reaction (ADR) by health professionals. Method: A systematic review carried out in the following databases: LILACS, PAHO, SciELO, EMBASE and PubMed in the period between 1992 and 2012. Descriptors were used in the search for articles, and the identified causes of underreporting were analyzed according to the classification of Inman. Results: In total, were identified 149 articles, among which 29 were selected. Most studies were carried out in hospitals (24/29) for physicians (22/29), and pharmacists (10/29). The main causes related to underreporting were ignorance (24/29), insecurity (24/29) and indifference (23/29). Conclusion: The data show the eighth sin in underreporting, which is the lack of training in pharmacovigilance. Therefore, continuing education can increase adherence of professionals to the service and improve knowledge and communication of risks due to drug use.

Surgical interventions for treating pectus excavatum

Background: Pectus excavatum is characterized by a depression of the anterior chest wall (sternum and lower costal cartilages) and is the most frequently occurring chest wall deformity. The prevalence ranges from 6.28 to 12 cases per 1000 around the world. Generally pectus excavatum is present at birth or is identified after a few weeks or months; however, sometimes it becomes evident only at puberty. The consequence of the condition on a individual's life is variable, some live a normal life and others have physical and psychological symptoms such as: precordial pain after exercises; impairments of pulmonary and cardiac function; shyness and social isolation. For many years, sub-perichondrial resection of the costal cartilages, with or without transverse cuneiform osteotomy of the sternum and placement of a substernal support, called conventional surgery, was the most accepted option for surgical repair of these patients. From 1997 a new surgical repair called, minimally invasive surgery, became available. This less invasive surgical option consists of the retrosternal placement of a curved metal bar, without resections of the costal cartilages or sternum osteotomy, and is performed by videothoracoscopy. However, many aspects that relate to the benefits and harms of both techniques have not been defined. Objectives: To evaluate the effectiveness and safety of the conventional surgery compared with minimally invasive surgery for treating people with pectus excavatum. Search methods: With the aim of increasing the sensitivity of the search strategy we used only terms related to the individual's condition (pectus excavatum); terms related to the interventions, outcomes and types of studies were not included. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, LILACS, and ICTPR. Additionally we searched yet reference lists of articles and conference proceedings. All searches were done without language restriction. Date of the most recent searches: 14 January 2014. Selection criteria: We considered randomized or quasi-randomized controlled trials that compared traditional surgery with minimally invasive surgery for treating pectus excavatum. Data collection and analysis: Two review authors independently assessed the eligibility of the trials identified and agreed trial eligibility after a consensus meeting. The authors also assessed the risk of bias of the eligible trials. Main results: Initially we located 4111 trials from the electronic searches and two further trials from other resources. All trials were added into reference management software and the duplicates were excluded, leaving 2517 studies. The titles and abstracts of these 2517 studies were independently analyzed by two authors and finally eight trials were selected for full text analysis, after which they were all excluded, as they did not fulfil the inclusion criteria. Authors' conclusions: There is no evidence from randomized controlled trials to conclude what is the best surgical option to treat people with pectus excavatum.

Safety assessment of essential medicines for elderly people: a bibliographic survey

Certain medicines are considered potentially inappropriate (PIM) for elderly people as they increase the risk of adverse drug events (ADE) and because safer alternative therapies are available on the market. In this context, in order to identify the instruments that assess the quality of medical prescriptions for elderly and to determine which drugs are considered PIM, a bibliographic survey was conducted in PUBMED, LILACS and PAHO databases, in February and March/2010. The search strategy included the use of health descriptors and a manual search in the references cited by selected papers. During the period of data collection, 15 instruments were identified. In 2012, with the publication of the update of Beers criteria, this instrument was included in the study. We identified 163 PIM of 25 therapeutic classes, of which 125 (76.7%) are marketed in Brazil. Of these, 31 (24.8%) are essential medicines (RENAME 2012), of which 13 have safer therapeutic equivalents and 19 (15.2%) are over-the-counter drugs. Data suggest the need for inclusion of safer alternatives for the elderly in the national list of essential medicines and the pharmaceutical care for early detection of ADE in this age group, in order to contribute to the safe use of medicines.

Impact of educational interventions on adverse drug events reporting

Spontaneous adverse drug events (ADE) reporting is the main source of data for assessing the risk/benefit of drugs available in the pharmaceutical market. However, its major limitation is underreporting, which hinders and delays the signal detection by Pharmacovigilance (PhV). To identify the techniques of educational intervention (EI) for promotion of PhV by health professionals and to assess their impact. A systematic review was performed in the PUBMED, PAHO, LILACS and EMBASE databases, from November/2011 to January/2012, updated in March/2013. The strategy search included the use of health descriptors and a manual search in the references cited by selected papers. 101 articles were identified, of which 16 met the inclusion criteria. Most of these studies (10) were conducted in European hospitals and physicians were the health professionals subjected to most EI (12), these studies lasted from one month to two years. EI with multifaceted techniques raised the absolute number, the rate of reporting related to adverse drug reactions (ADR), technical defects of health technologies, and also promoted an improvement in the quality of reports, since there was increased reporting of ADR classified as serious, unexpected, related to new drugs and with high degree of causality. Multifaceted educational interventions for multidisciplinary health teams working at all healthcare levels, with sufficient duration to reach all professionals who act in the institution, including issues related to medication errors and therapeutic ineffectiveness, must be validated, with the aim of standardizing the Good Practice of PhV and improve drug safety indicators.
