Sintomas Mentais e Consumo de Álcool por Estudantes da UNESP, Instituto de Biociências de Rio Claro, S.P

Esta pesquisa teve como objetivo caracterizar os padrões de consumo de bebida alcoólica e a prevalência de indicadores de ansiedade e depressão, em universitários. Foram investigados 200 alunos, em série consecutiva, oriundos dos cursos de Biologia, Ecologia, Educação Física e Pedagogia. Os métodos consistiram na aplicação de escalas especializadas para verificação de padrões de consumo de álcool e sintomas de ansiedade e depressão, respectivamente, o SADD (Short Alcohol Dependence Data) e a HAD (Hospital Anxiety and Depression Scale). Os resultados mostraram que, dos 200 alunos, 17 (8,5%) apresentavam comportamento de uso abusivo de álcool, com riscos para a saúde física e mental. Ainda, 53 alunos (26,5%) revelaram indicadores positivos de ansiedade e 16 (8%), de depressão. Destes 53 alunos com indicadores positivos de ansiedade, 8 (15,1%) faziam uso abusivo de álcool e, dos 16 alunos com sintomas depressivos, 8 (50%) tinham comportamento de consumo abusivo de álcool, com riscos para a saúde física e mental. Os autores concluíram que o uso abusivo de álcool pode estar associado à presença de sofrimento psíquico, principalmente ansiedade e depressão. E propõem que se discuta a necessidade de criação de um Serviço de Saúde Mental para atendimento da comunidade universitária.

Influência de fluídos biológicos na sobrevivência de Staphylococcus aureus sobre diferentes superfícies secas

Sabe-se que a transmissão de infecções hospitalares, via cruzada ou ambiental, é facilitada pela sobrevivência de microrganismos em superfícies secas que pode ser favorecida pela presença de fluídos biológicos. Visando demonstrar o cuidado com substâncias corporais na rotina de limpeza, esse estudo avaliou a influência de alguns fluídos biológicos (sangue, urina e saliva artificial) na sobrevivência de Staphylococcus aureus (ATCC 25923), depositados de modo similar, sobre diferentes superfícies após secagem. O sangue foi capaz de preservar a viabilidade bacteriana por até 72 dias quando depositado sobre piso cerâmico. O tecido em fibra de algodão permitiu maior tempo de sobrevivência em comparação ao tecido sintético. Esses resultados demonstram que a composição do fluído biológico e o tipo de suporte altera o tempo da sobrevivência bacteriana em condições ambientais.

Between the processes of strengthening and weakening of the Family Health Strategy

This was a qualitative study with the purpose of designing a meta-model for the work process of the Family Health Strategy (FHS) team. It was based on the experience of six sample groups, composed of their members (physicians, professional nurses, dentists, dental assistants, licensed technical nurses and community health agents) in a city in São Paulo state, Brazil, totaling 54 subjects. Six theoretical models emerged from non-directive interviews. These were analyzed according to Grounded Theory and submitted to the meta-synthesis strategy, which produced the meta-model between the processes of strengthening and weakening of the FHS model: professional-team-community reciprocity as an intervening component. When analyzed in light of the Theory of Complexity (TC), it showed to be a work with a vertical and authoritarian tendency, which is largely hegemonic in the tradition of public health care policies.

Revendo estudos sobre a assistência domiciliar ao idoso

Home care presents itself as a new modality of care for the elderly, especially in Brazil , and has been inserted into public policies. This study aims to identify scientific productions about home care, in order to ascertain which are the contributions of this social dynamic in the elderly. The research was conducted in the databases MEDLINE and LILACS, with articles published between the years 2001- 2011, in Portuguese and English. The combination of keywords used was home care and elderly , elderly and care, and elderly and caregiver, and correspondents in Portuguese. The discussion highlighted the importance of home care, especially for lonely or neglected elderly. The review revealed few studies concerning the social dynamics in the home care of the elderly and the need to broaden the discussion beyond the field of health.

Prevention of repeated episodes of type 2 reaction of leprosy with the use of thalidomide 100 mg/day

BACKGROUND: Leprosy can have its course interrupted by type 1 and 2 reactional episodes, the last named of erythema nodosum leprosum (ENL). Thalidomide has been the medication of choice for the control of ENL episodes since 1965. OBJECTIVES: These episodes can repeat and cause damages to the patient. In order to prevent these episodes, an extra dose of 100 mg/day thalidomide was used during six months, followed by a follow-up period of six more months after thalidomide discontinuation. METHODS: We included 42 patients with multibacillary (MB) leprosy who had episodes of ENL. They were male and female patients aged between 18 and 84 years. RESULTS: Of the 42 patients, 39 (92.85%) had the lepromatous form and three (7.15%) had the borderline form. We found that 100% of patients had no reactional episode during the use of the drug. During the follow-up period after thalidomide discontinuation, 33 (78.57%) patients had no reactional episode and nine (21.43%), all of them with the lepromatous form, had mild episodes, which were controlled using non-steroidal anti-inflammatory. There were no thalidomide-related side effects. CONCLUSION: A maintenance dose of 100 mg/day of thalidomide showed to be effective to prevent repeated type 2 reactional episodes of ENL.

New treatment strategies for Alzheimer's disease: is there a hope?

Alzheimer's disease (AD) is a progressive and irreversible neurodegenerative disease, and corresponds to the most common cause of dementia worldwide. Although not fully understood, the pathophysiology of AD is largely represented by the neurotoxic events triggered by the beta-amyloid cascade and by cytoskeletal abnormalities subsequent to the hyperphosphorylation of microtubule-associated Tau protein in neurons. These processes lead respectively to the formation of neuritic plaques and neurofibrillary tangles, which are the pathological hallmarks of the disease. Clinical benefits of the available pharmacological treatment for AD with antidementia drugs (namely cholinesterase inhibitors and memantine) are unquestionable, although limited to a temporary, symptomatic support to cognitive and related functions. Over the past decade, substantial funding and research have been dedicated to the search and development of new pharmaceutical compounds with disease-modifying properties. The rationale of such approach is that by tackling key pathological processes in AD it may be possible to attenuate or even change its natural history. In the present review, we summarize the available evidence on the new therapeutic approaches that target amyloid and Tau pathology in AD, focusing on pharmaceutical compounds undergoing phase 2 and phase 3 randomized controlled trials.

Neuropsychiatric symptoms in the prodromal stages of dementia

Purpose of reviewTo critically discuss the neuropsychiatric symptoms in the prodromal stages of dementia in order to improve the early clinical diagnosis of cognitive and functional deterioration.Recent findingsCurrent criteria for cognitive syndrome, including Alzheimer's disease, comprise the neuropsychiatric symptoms in addition to cognitive and functional decline. Although there is growing evidence that neuropsychiatric symptoms may precede the prodromal stages of dementia, these manifestations have received less attention than traditional clinical hallmarks such as cognitive and functional deterioration. Depression, anxiety, apathy, irritability, agitation, sleep disorders, among other symptoms, have been hypothesized to represent a prodromal stage of dementia or, at least, they increase the risk for conversion from minor neurocognitive disorder to major neurocognitive disorder. Longitudinal investigations have provided increased evidence of progression to dementia in individuals with minor neurocognitive disorder when neuropsychiatric symptoms also were present.SummaryAlthough neuropsychiatric symptoms are strongly associated with a higher risk of cognitive and functional deterioration, frequently the clinician does not acknowledge these conditions as increasing the risk of dementia. When the clinician accurately diagnoses neuropsychiatric symptoms in the prodromal stage of dementia, he could early establish appropriate treatment and, may be, delay the beginning of clinical and functional deterioration.

Acolhimento na estratégia saúde da família:revisão integrativa

Objective. To review the literature regarding the application of the notion of user embracement and to identify the contributions of this concept for primary health care practices in Brazil.Method. We carried out an integrative review of the literature regarding primary health care. The following databases were searched: LILACS, SciELO, and MEDLINE, covering the period from 2006 to 2010. The following search terms were used in LILACS and SciELO: acolhimento and programa saude da familia and saude. For MEDLINE, the terms user embracement and family health program and health were used. The review was performed in November 2010.Results. We identified 21 articles meeting the inclusion criteria, all of which described studies carried out in Brazil. The articles were divided into three empirical categories: integration and embracement; primary care work process; and evaluation of services. These are complementary categories that converge to two main views of embracement: the first sees embracement as a means of reorganizing the primary health care environment, and the second sees embracement as an attitude towards users. The review also shows that embracement may be a management tool that supports the Unified Health System and is associated with the principles of comprehensiveness and universality.Conclusions. Embracement is able to create a bond between health care workers and users. It promotes self-care, a better understanding of disease, as well as user co-responsibility for treatment. In addition, it facilitates universal access, strengthens multiprofessional and intersectoral work, qualifies care, humanizes practices, and encourages actions to combat prejudice. Nevertheless, the perspective of health care users regarding embracement deserves more attention and should be the focus of future studies.

Evaluation of bond strength and thickness of adhesive layer according to the techniques of applying adhesives in composite resin restorations

Adhesive restorations have increasingly been used in dentistry, and the adhesive system application technique may determine the success of the restorative procedure. The aim of this study was to evaluate the influence of the application technique of two adhesive systems (Clearfil SE Bond and Adper Scotchbond MultiPurpose) on the bond strength and adhesive layer of composite resin restorations. Eight human third molars were selected and prepared with Class I occlusal cavities. The teeth were restored with composite using various application techniques for both adhesives, according to the following groups (n = 10): group 1 (control), systems were applied and adhesive was immediately light activated for 20 seconds without removing excesses; group 2, excess adhesive was removed with a gentle jet of air for 5 seconds; group 3, excess was removed with a dry microbrush-type device; and group 4, a gentle jet of air was applied after the microbrush and then light activation was performed. After this, the teeth were submitted to microtensile testing. For the two systems tested, no statistical differences were observed between groups 1 and 2. Groups 3 and 4 presented higher bond strength values compared with the other studied groups, allowing the conclusion that excess adhesive removal with a dry micro-brush could improve bond strength in composite restorations. Predominance of adhesive fracture and thicker adhesive layer were observed via scanning electron microscopy (SEM) in groups 1 and 2. For groups 3 and 4, a mixed failure pattern and thinner adhesive layer were verified. Clinicians should be aware that excess adhesive may negatively affect bond strength, whereas a thin, uniform adhesive layer appears to be favorable. (Quintessence Int 2013;44:9-15)

Benefits of Multimodal Exercise Intervention for Postural Control and Frontal Cognitive Functions in Individuals with Alzheimer's Disease: A Controlled Trial

Objective To verify the effects of a systematized multimodal exercise intervention program on frontal cognitive function, postural control, and functional capacity components of individuals with Alzheimer's disease (AD).DesignNonrandomized controlled trial with pre- and posttraining tests in a training group and a control group.SettingKinesiotherapy program for seniors with AD, SAo Paulo State University.ParticipantsConvenience sample of older adults with AD (n=30) were assigned to a training (n=14; aged 78.67.1) and a control (n=16; aged 77.06.3) group.InterventionThe intervention program was structured with the aim of simultaneously promoting better balance and frontal cognitive capacity. The participants attended a 1-hour session three times a week for 16weeks, whereas the control group did not participate in any activity during the same period.MeasurementsFrontal cognitive function was evaluated using the Montreal Cognitive Assessment, the Clock Drawing Test, the Frontal Assessment Battery, and the Symbol Search Subtest. Postural control (center of pressure area) was analyzed under four dual-task conditions. Functional capacity components were analyzed using the Timed Up and Go Test, the 30-second sit-to-stand test, the sit-and-reach test, and the Berg Functional Balance Scale.ResultsIntervention group participants showed a significant increase in frontal cognitive function (P<.001, partial (2)=0.838), with less body sway (P=.04, partial (2)=0.04) during the dual tasks, and greater functional capacity (P=.001, partial (2)=0.676) after the 16-week period.ConclusionIntervention participants performed better on dual-task activities and had better postural balance and greater functional capacity than controls.
