Measurements of adequacy of anesthesia and level of consciousness during surgery and intensive care

The adequacy of anesthesia has been studied since the introduction of balanced general anesthesia. Commercial monitors based on electroencephalographic (EEG) signal analysis have been available for monitoring the hypnotic component of anesthesia from the beginning of the 1990s. Monitors measuring the depth of anesthesia assess the cortical function of the brain, and have gained acceptance during surgical anesthesia with most of the anesthetic agents used. However, due to frequent artifacts, they are considered unsuitable for monitoring consciousness in intensive care patients. The assessment of analgesia is one of the cornerstones of general anesthesia. Prolonged surgical stress may lead to increased morbidity and delayed postoperative recovery. However, no validated monitoring method is currently available for evaluating analgesia during general anesthesia. Awareness during anesthesia is caused by an inadequate level of hypnosis. This rare but severe complication of general anesthesia may lead to marked emotional stress and possibly posttraumatic stress disorder. In the present series of studies, the incidence of awareness and recall during outpatient anesthesia was evaluated and compared with that of in inpatient anesthesia. A total of 1500 outpatients and 2343 inpatients underwent a structured interview. Clear intraoperative recollections were rare the incidence being 0.07% in outpatients and 0.13% in inpatients. No significant differences emerged between outpatients and inpatients. However, significantly smaller doses of sevoflurane were administered to outpatients with awareness than those without recollections (p<0.05). EEG artifacts in 16 brain-dead organ donors were evaluated during organ harvest surgery in a prospective, open, nonselective study. The source of the frontotemporal biosignals in brain-dead subjects was studied, and the resistance of bispectral index (BIS) and Entropy to the signal artifacts was compared. The hypothesis was that in brain-dead subjects, most of the biosignals recorded from the forehead would consist of artifacts. The original EEG was recorded and State Entropy (SE), Response Entropy (RE), and BIS were calculated and monitored during solid organ harvest. SE differed from zero (inactive EEG) in 28%, RE in 29%, and BIS in 68% of the total recording time (p<0.0001 for all). The median values during the operation were SE 0.0, RE 0.0, and BIS 3.0. In four of the 16 organ donors, EEG was not inactive, and unphysiologically distributed, nonreactive rhythmic theta activity was present in the original EEG signal. After the results from subjects with persistent residual EEG activity were excluded, SE, RE, and BIS differed from zero in 17%, 18%, and 62% of the recorded time, respectively (p<0.0001 for all). Due to various artifacts, the highest readings in all indices were recorded without neuromuscular blockade. The main sources of artifacts were electrocauterization, electromyography (EMG), 50-Hz artifact, handling of the donor, ballistocardiography, and electrocardiography. In a prospective, randomized study of 26 patients, the ability of Surgical Stress Index (SSI) to differentiate patients with two clinically different analgesic levels during shoulder surgery was evaluated. SSI values were lower in patients with an interscalene brachial plexus block than in patients without an additional plexus block. In all patients, anesthesia was maintained with desflurane, the concentration of which was targeted to maintain SE at 50. Increased blood pressure or heart rate (HR), movement, and coughing were considered signs of intraoperative nociception and treated with alfentanil. Photoplethysmographic waveforms were collected from the contralateral arm to the operated side, and SSI was calculated offline. Two minutes after skin incision, SSI was not increased in the brachial plexus block group and was lower (38 ± 13) than in the control group (58 ± 13, p<0.005). Among the controls, one minute prior to alfentanil administration, SSI value was higher than during periods of adequate antinociception, 59 ± 11 vs. 39 ± 12 (p<0.01). The total cumulative need for alfentanil was higher in controls (2.7 ± 1.2 mg) than in the brachial plexus block group (1.6 ± 0.5 mg, p=0.008). Tetanic stimulation to the ulnar region of the hand increased SSI significantly only among patients with a brachial plexus block not covering the site of stimulation. Prognostic value of EEG-derived indices was evaluated and compared with Transcranial Doppler Ultrasonography (TCD), serum neuron-specific enolase (NSE) and S-100B after cardiac arrest. Thirty patients resuscitated from out-of-hospital arrest and treated with induced mild hypothermia for 24 h were included. Original EEG signal was recorded, and burst suppression ratio (BSR), RE, SE, and wavelet subband entropy (WSE) were calculated. Neurological outcome during the six-month period after arrest was assessed with the Glasgow-Pittsburgh Cerebral Performance Categories (CPC). Twenty patients had a CPC of 1-2, one patient had a CPC of 3, and nine patients died (CPC 5). BSR, RE, and SE differed between good (CPC 1-2) and poor (CPC 3-5) outcome groups (p=0.011, p=0.011, p=0.008, respectively) during the first 24 h after arrest. WSE was borderline higher in the good outcome group between 24 and 48 h after arrest (p=0.050). All patients with status epilepticus died, and their WSE values were lower (p=0.022). S-100B was lower in the good outcome group upon arrival at the intensive care unit (p=0.010). After hypothermia treatment, NSE and S-100B values were lower (p=0.002 for both) in the good outcome group. The pulsatile index was also lower in the good outcome group (p=0.004). In conclusion, the incidence of awareness in outpatient anesthesia did not differ from that in inpatient anesthesia. Outpatients are not at increased risk for intraoperative awareness relative to inpatients undergoing general anesthesia. SE, RE, and BIS showed non-zero values that normally indicate cortical neuronal function, but were in these subjects mostly due to artifacts after clinical brain death diagnosis. Entropy was more resistant to artifacts than BIS. During general anesthesia and surgery, SSI values were lower in patients with interscalene brachial plexus block covering the sites of nociceptive stimuli. In detecting nociceptive stimuli, SSI performed better than HR, blood pressure, or RE. BSR, RE, and SE differed between the good and poor neurological outcome groups during the first 24 h after cardiac arrest, and they may be an aid in differentiating patients with good neurological outcomes from those with poor outcomes after out-of-hospital cardiac arrest.

Depressive Disorders in Primary Health Care

The Vantaa Primary Care Depression Study (PC-VDS) is a naturalistic and prospective cohort study concerning primary care patients with depressive disorders. It forms a collaborative research project between the Department of Mental and Alcohol Research of the National Public Health Institute, and the Primary Health Care Organization of the City of Vantaa. The aim is to obtain a comprehensive view on clinically significant depression in primary care, and to compare depressive patients in primary care and in secondary level psychiatric care in terms of clinical characteristics. Consecutive patients (N=1111) in three primary care health centres were screened for depression with the PRIME-MD, and positive cases interviewed by telephone. Cases with current depressive symptoms were diagnosed face-to-face with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I/P). A cohort of 137 patients with unipolar depressive disorders, comprising all patients with at least two depressive symptoms and clinically significant distress or disability, was recruited. The Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II), medical records, rating scales, interview and a retrospective life-chart were used to obtain comprehensive cross-sectional and retrospective longitudinal information. For investigation of suicidal behaviour the Scale for Suicidal Ideation (SSI), patient records and the interview were used. The methodology was designed to be comparable to The Vantaa Depression Study (VDS) conducted in secondary level psychiatric care. Comparison of major depressive disorder (MDD) patients aged 20-59 from primary care in PC-VDS (N=79) was conducted with new psychiatric outpatients (N =223) and inpatients (N =46) in VDS. The PC-VDS cohort was prospectively followed up at 3, 6 and 18 months. Altogether 123 patients (90%) completed the follow-up. Duration of the index episode and the timing of relapses or recurrences were examined using a life-chart. The retrospective investigation revealed current MDD in most (66%), and lifetime MDD in nearly all (90%) cases of clinically significant depressive syndromes. Two thirds of the “subsyndromal” cases had a history of major depressive episode (MDE), although they were currently either in partial remission or a potential prodromal phase. Recurrences and chronicity were common. The picture of depression was complicated by Axis I co-morbidity in 59%, Axis II in 52% and chronic Axis III disorders in 47%; only 12% had no co-morbidity. Within their lifetimes, one third (37%) had seriously considered suicide, and one sixth (17%) had attempted it. Suicidal behaviour clustered in patients with moderate to severe MDD, co-morbidity with personality disorders, and a history of treatment in psychiatric care. The majority had received treatment for depression, but suicidal ideation had mostly remained unrecognised. The comparison of patients with MDD in primary care to those in psychiatric care revealed that the majority of suicidal or psychotic patients were receiving psychiatric treatment, and the patients with the most severe symptoms and functional limitations were hospitalized. In other clinical aspects, patients with MDD in primary care were surprisingly similar to psychiatric outpatients. Mental health contacts earlier in the current MDE were common among primary care patients. The 18-month prospective investigation with a life-chart methodology verified the chronic and recurrent nature of depression in primary care. Only one-quarter of patients with MDD achieved and maintained full remission during the follow-up, while another quarter failed to remit at all. The remaining patients suffered either from residual symptoms or recurrences. While severity of depression was the strongest predictor of recovery, presence of co-morbid substance use disorders, chronic medical illness and cluster C personality disorders all contributed to an adverse outcome. In clinical decision making, beside severity of depression and co-morbidity, history of previous MDD should not be ignored by primary care doctors while depression there is usually severe enough to indicate at least follow-up, and concerning those with residual symptoms, evaluation of their current treatment. Moreover, recognition of suicidal behaviour among depressed patients should also be improved. In order to improve outcome of depression in primary care, the often chronic and recurrent nature of depression should be taken into account in organizing the care. According to literature management programs of a chronic disease, with enhancement of the role of case managers and greater integration of primary and specialist care, have been successful. Optimum ways of allocating resources between treatment providers as well as within health centres should be found.

Suicidal ideation and attempts among psychiatric patients with major depressive disorder

This study is part of an ongoing collaborative research and development project, the Vantaa Depression Study (VDS), between the National Public Health Institute, Helsinki and the Department of Psychiatry of Helsinki University Hospital (HUCH), Peijas hospital, Vantaa. The VDS is a prospective, naturalistic cohort study of 269 secondary-level care psychiatric out- and inpatients with a new episode of DSM-IV major depressive disorder (MDD). 269 patients (Nmales=72, Nfemales=197) with a current DSM-IV MDD were interviewed with semistructured interviews to assess all other psychiatric diagnoses. At 6- and 18-month follow-up the interviews were repeated. Suicidal behaviour was investigated both at intake and follow-up by using a psychometric scale (Scale for Suicidal Ideation) and interviewer's questions as well as the patient's psychiatric records. Patients, who reported suicidal ideation while entering the study were followed up weekly, and their level of suicidal ideation, hopelessness, anxiety and depression was measured. In this study suicidal ideation was common among psychiatric patients with MDD. Almost 60% of the depressed patients reported suicidal ideation and 15% of patients attempted suicide at the baseline. Patients with suicidal ideation or attempts had a clearly higher level of overall psychopathology than non-suicidal patients. During the 18-month follow-up period 8% of patients attempted suicide. The risk of an attempt was markedly higher (RR=7.54) during an episode of major depression compared with a period of remission. Suicide attempt during the follow-up period was predicted by lack of partner, a history of previous suicide attempts and time spent in depression. Suicidal ideation resolved for most of the suicidal patients during the first 2 to 3 months. The duration of suicidal ideation was longer for patients with an initially higher level of psychopathology. Declines both in depression and hopelessness independently predicted the subsequent decline in suicidal ideation. They both could have a causal role in reversing the suicidal process. Thus effective treatment of depression is a credible measure in suicide prevention. Patients with suicidal behaviour often received more antidepressants and had more frequent appointments with mental health professionals than non-suicidal patients. Suicidal patients had also more favourable attitudes towards antidepressant treatment and comparable adherence to treatment than those not suicidal. This study does not support the conception that patient attitudes or adherence to treatments would be a factor differentiating suicidal patients from non-suicidal. Instead, problems with adherence or attitudes seem to be generic to all psychiatric care.

Parathyroid hormone as an outcome indicator in old age

Serum parathyroid hormone (PTH) and vitamin D are the major regulators of extracellular calcium homeostasis. The inverse association between PTH and vitamin D and the common age-related elevation of the PTH concentration are well known phenomena. However, the confounding or modifying factors of this relationship and their impact on the response of PTH levels to vitamin D supplementation need further investigation. Clinical conditions such as primary hyperparathyroidism (PHPT), renal failure and vitamin D deficiency, characterized by an elevation of the PTH concentration, have been associated with impaired long-term health outcomes. Curative treatments for these conditions have also been shown to decreases PTH concentration and attenuate some of the adverse health effects. In PHPT it has also been commonly held that hypercalcaemia, the other hallmark of the disease, is the key mediator of the adverse health outcomes. In chronic kidney disease the systemic vascular disease has been proposed to have the most important impact on general health. Some evidence also indicates that vitamin D may have significant extraskeletal actions. However, the frank elevation of PTH concentration seen in advanced PHPT and in end-stage renal failure have also been suggested to be at least partly causally related to an increased risk of death as well as cognitive dysfunction. However, the exact mechanisms have remained unclear. Furthermore, the predictive value of elevated PTH in unselected older populations has been less well studied. The studies presented in this thesis investigated the impact of age and mobility on the responses of PTH levels to vitamin D deficiency and supplementation. Furthermore, the predictive value of PTH for long-term survival and cognitive decline was addressed in an unselected population of older people. The hypothesis was that age and chronic immobility are related to a persistently blunted elevation of PTH concentration, even in the presence of chronic vitamin D deficiency, and to attenuated responses of PTH to vitamin D supplementation. It was also further hypothesized that a slightly elevated or even high-normal PTH concentration is an independent indicator of an increased risk of death and cognitive decline in the general aged population. The data of this thesis are based on three samples: a meta-analysis of published vitamin D supplementation trials, a randomized placebo controlled six-month vitamin D supplementation trial, and a longitudinal prospective cohort study on a general aged population. Based on a PubMed search, a meta-analysis of 52 clinical trials with 6 290 adult participants was performed to evaluate the impact of age and immobility on the responses of PTH to 25-OHD levels and vitamin D supplementation. A total of 218 chronically immobile, very old inpatients were also enrolled into a vitamin D supplementation trial. Mortality data for these patients was also collected after a two-year follow-up. Finally, data from the Helsinki Aging Study, which followed three random age cohorts (75, 80 and 85 years) until death in almost all subjects, was used to evaluate the predictive value of PTH for long-term survival and cognitive decline. This series of studies demonstrated that in older people without overt renal failure or severe hypercalcaemia, serum 25-OHD and PTH were closely associated, but this relationship was also affected by age and immobility. Furthermore, a substantial proportion of old chronically bedridden patients did not respond to vitamin D deficiency by elevating PTH, and the effect of a high-dose (1200 IU/d) six-month cholecalciferol supplementation on the PTH concentration was minor. This study demonstrated longitudinally for the first time that the blunted PTH also persisted over time. Even a subtle elevation of PTH to high-normal levels predicted impaired long-term health outcomes. Slightly elevated PTH concentrations indicated an increased risk of clinically significant cognitive decline and death during the last years of life in a general aged population. This association was also independent of serum ionized calcium (Ca2+) and the estimated glomerular filtration rate (GFR). A slightly elevated PTH also indicated impaired two-year survival during the terminal years of frail elderly subjects independently of Ca2+, GFR, and of 25-OHD levels. The interplay between PTH and vitamin D in the regulation of calcium homeostasis is more complex than has been generally considered. In addition to muskuloskeletal health parathyroid hormone is also related to the maintenance of other important domains of health in old age. Higher PTH concentrations, even within conventional laboratory reference ranges, seem to be an independent indicator of an increased risk of all-cause and of cardiovascular mortality, independently of established cardiovascular risk factors, disturbances in mineral metabolism, and renal failure. Limited and inconsistent evidence supports the role of vitamin D deficiency-related lack of neuroprotective effects over the causal association between PTH and impaired cognitive functions. However, the causality of these associations remains unclear. The clinical implications of the observed relationships remain to be elucidated by future studies interfering with PTH concentrations, especially by long-term interventions to reduce PTH.

Análise da atenção prestada aos pacientes portadores de hipertensão arterial no município de Piraí com bases nos registros dos prontuários ambulatoriais e hospitalares

O controle da Hipertensão Arterial é central para que seja alcançada maior eficiência na redução de eventos adversos secundários ao descontrole crônico da pressão arterial. Os resultados de uma atenção integral aos portadores não se esgotam no acesso e disponibilização de fármacos eficazes no controle da pressão arterial. Ela envolve a rede integrada de serviços, orientada pela atenção primária, com serviços especializados e hospitalares na atenção das intercorrências. O cuidado aos portadores destes agravos crônicos exige dos serviços e profissionais da atenção primária a implantação de estratégias de acolhimento, efetivação de vínculos e projetos terapêuticos e uma intervenção que abrange a promoção, prevenção, assistência e reabilitação. Com esta questão em mente é que este projeto buscou analisar a atenção prestada aos portadores de Hipertensão Arterial no município de Piraí com base nos registros dos prontuários ambulatoriais e hospitalares. Foram computados e analisados os prontuários de pacientes internados por agravos que, direta ou indiretamente, estão relacionados ao descontrole da pressão arterial. Identificaram-se um total de 61 pacientes internados com diagnóstico de internação de Crise Hipertensiva e Acidente Vascular Encefálico no ano de 2010, no Hospital Flávio Leal. A partir dos registros hospitalares foram selecionados 35 pacientes. Estes eram moradores do município de Piraí, adscritos a equipes básicas no município e tiveram seus diagnósticos de internação confirmados na alta hospitalar. A segunda etapa do estudo analisou, na Unidade de Saúde da Família, os prontuários familiares dos casos de internação. Foi observado que não havia uniformidade na forma de registro e de arquivamento dos prontuários entre as unidades básicas. Nos prontuários clínicos não havia campos destinados aos registros de aspectos psicossociais, mudança de comportamento ou adesão. As anotações eram centradas na doença e nos tratamentos farmacológicos. A participação de profissionais não médicos nos registros clínicos era escassa. A Ficha B do SIAB (Ficha de Acompanhamento do Paciente Hipertenso) que contém os dados sobre comportamento e risco cardiovascular foi encontrada apenas em 3 das 8 unidades visitadas. Segundo os dados dos prontuários analisados a distribuição de consultas e visitas domiciliares foi muito irregular. Com um total de 10 prontuários sem registros de consultas no ano em que o pacientes foi internado. A gravidade dos pacientes internados pode ser identificada pelo elevado número de óbitos entre os casos analisados. Muitos dos casos apresentavam sequelas neurológicas e comorbidades que provavelmente dificultava suas idas às unidades de saúde da família. Aspectos psicossociais, familiares e da comunidade estavam, em sua maioria, ausente dos prontuários familiares analisados dos pacientes internados. Também não foram encontrados anotações sobre projetos terapêuticos multidisciplinares que individualizassem e hierarquizassem os agravos e os riscos físicos e psicossociais dos pacientes. A análise evidencia que os registros nos prontuários não traduzem a abrangência de uma atenção integral aos portadores de Hipertensão Arterial no âmbito da Atenção Primária.

Perfis de resistência de cepas de Escherichia coli isoladas em urocultura e a correlação com os fatores de risco diversos para infecção do trato urinário

As infecções do trato urinário (ITUs) são uma das causas mais comuns de consultas médicas. No ambiente hospitalar estão entre as mais frequentes infecções relacionadas à assistência à saúde (35 a 45%). Nos Estados Unidos da América, resultam em 3.600.000 consultas médicas anuais e mais de 100.000 hospitalizações. No Reino Unido, representam 23% das infecções relacionadas à assistência à saúde. Estudos mostram que a E. coli é a bactéria mais isolada em uroculturas (75% a 80%), tanto em pacientes hospitalizados quanto não hospitalizados. A antibioticoterapia para ITU é comumente iniciada empiricamente, antes da urocultura e do antibiograma, por isso, faz-se necessário conhecer a sensibilidade e resistência dos prováveis agentes etiológicos, deve-se considerar o histórico clínico epidemiológico do paciente. No presente estudo foi realizada a análise da resistência das cepas de E. coli isoladas em 261 uroculturas de pacientes assistidos no serviço ambulatorial e hospitalar do Hospital Universitário Pedro Ernesto (HUPE) e, também, de 81 cepas isoladas em uroculturas de pacientes assistidos no serviço ambulatorial de um Hospital Maternidade do Município do Rio de Janeiro (HMMRJ), no período de maio de 2010 a dezembro de 2010. A susceptibilidade aos antimicrobianos foi determinada pela metodologia de disco difusão por Kirby e Bauer. Foram realizadas triagens fenotípicas para cepas produtoras de ESBL e para cepas produtoras de carbapenemases. Através dos dados contidos nos prontuários dos pacientes com uroculturas positivas para E. coli (≥ 105 ufc/mL), foi realizada a pesquisa clínica epidemiológica para se verificar a ocorrência de fatores de risco diversos, para ITU por E. coli. Observou-se que pacientes do sexo feminino são mais susceptíveis a ITU e o uso de antibiótico até 03 meses antes do episódio infeccioso (p= 0,04746), diabetes (p= 0,01683), trauma recente (p= 0,000238), cirurgia abdominal ou pélvica prévia (p= 0,00221), patologia crônica de bexiga (p= 0,002150), uso de cateter urinário (p=0,0002), insuficiência renal crônica (p= 0,02178), e hospitalização por até 06meses prévios (p= 0,01802) podem ser considerados fatores de risco para ITU por E. coli. Verificou-se que o uso de cateter urinário (p=0,000399), cirurgia abdominal ou pélvica prévia (p=0,004458) e o uso de antimicrobianos prévios ao processo infeccioso (p=0,002625), podem ser considerados fatores de risco importantes, para ITU por E. coli multirresistentes. Os pacientes do sexo masculino, apesar de minoria no estudo, representam a maioria dos pacientes com ITU por E. coli multirresistente. Verificou-se que a classe de antimicrobiano utilizado previamente ao episódio infeccioso, aumenta a chance de ocorrer ITU por E. coli multirresistente, principalmente quando associadas ao uso de cateter urinário e cirurgia abdominal ou pélvica prévia. Os perfis de resistência da cepas isoladas dos pacientes assistidos no serviço ambulatorial e hospitalar do HUPE apresentam semelhanças. Apesar do baixo número de cepas multirresistentes entre as isoladas dos pacientes assistidos no serviço ambulatorial do HMMRJ, essas apresentam perfil de resistência semelhante aos perfis das cepas isoladas dos pacientes assistidos no serviço ambulatorial e hospitalar do HUPE. A partir das evidências, percebe-se que o uso racional de antimicrobianos é muito importante para diminuir a problemática da resistência bacteriana

O trabalho político do profissional de saúde mental em um processo de desinstitucionalização: um estudo sobre integralidade e reforma psiquiátrica

O trabalho pretende apresentar uma cartografia das atividades desenvolvidas pelos profissionais de saúde mental que prestam assistência aos moradores dos serviços residenciais terapêuticos do município de Carmo, no Estado do Rio de Janeiro. Estas moradias constituem uma etapa do processo de desinstitucionalização de um hospital psiquiátrico estadual do tipo colônia agrícola, fundado na década de 40 do século passado, onde estavam internados cerca de 280 pacientes. A partir de 2003, com a extinção do hospital coordenada pelo gestor estadual e a municipalização dos recursos, uma pequena parcela dos internos retornou ao seio familiar, mas a maioria (cerca de 160) foi alocada em moradias assistidas, espalhadas pelas áreas urbana e rural do município. Tomando a tarefa de reinserção social como o viés político da Reforma Psiquiátrica Brasileira, o trabalho cotidiano da equipe multiprofissional é focalizado. Neste plano relacional o texto busca a conceitualização de Política e de um trabalho político, através das idéias de Arendt, Gramsci, Deleuze e Guattari, entre outros; já a ergologia possibilita uma metodologia para a abordagem do trabalho humano. Com base na pesquisa de campo, a cartografia revela como a tarefa política é realizada, nas atividades dos técnicos, quer dizer, na micropolítica dos encontros dos profissionais uns com os outros, com a sociedade civil e com os moradores, onde os valores da Reforma Psiquiátrica são negociados. No fim, trata-se de uma etapa em um processo, ainda a meio caminho entre a gestão estadual e a gestão municipal, onde a proposta mantém-se sustentada pela vontade política do gestor e, na via da hegemonia, deve ser trabalhada entre os profissionais e na sociedade civil. O panorama é heterogêneo, e a dinâmica revela a diversidade de entendimentos e interesses. No cenário do trabalho cotidiano, conceitos como autonomia e cidadania se atualizam em atividades que caracterizam a vida nas cidades e se desdobram em torno de certos temas, como o uso do dinheiro, ou a apropriação do espaço. A experiência dos técnicos envolvidos mais diretamente com os moradores, como os cuidadores, produz uma técnica de escuta e mobilização, que não admite cartilhas nem regras pré-estabelecidas ou imutáveis. Este trabalho conjunto, formador de redes e sustentado na interação, é indicador de integralidade na execução da proposta da Reforma Psiquiátrica.

O processo de consolidação da Política Nacional de Saúde Bucal: a atenção terciária como desafio da segunda década da política de saúde bucal do SUS

Esta tese tem por objeto descrever e analisar o processo de desenvolvimento da Política Nacional de Saúde Bucal (PNSB) no terceiro nível de atenção. Para entender esse desenvolvimento, foram realizados três macroprocessos de pesquisa. O primeiro grupo de pesquisas procurou mapear a distribuição espacial dos hospitais com disponibilidade de leitos/SUS nos país e saber, dentre estes, quantos contam com serviços de atenção à saúde bucal cadastrados no Sistema de Cadastro Nacional de Estabelecimentos de Saúde (SCNES). O segundo grupo de pesquisas se ocupou em levantar junto ao DATASUS, através das ferramentas de consulta TABNET e TABWIN, dados nacionais relativos ao movimento das Autorizações de Internação Hospitalar (AIH) voltadas para procedimento de código 041402041-3 cuja descrição é Tratamento Odontológico para Pacientes com Necessidades Especiais em todas as unidades hospitalares que apresentaram este tipo de produção no país no biênio 2011/12. Foram consideradas 15 categorias de análise. O terceiro grupo de pesquisas buscou levantar junto ao site do Ministério da Saúde dados das Comissões Intergestores Regionais (CIR) existentes no Brasil até dezembro de 2012 assim como os Planos Diretores de Regionalização (PDR) e os Planos Estaduais de Saúde (PES) dos 26 estados e do Distrito Federal. Os resultados da pesquisa foram cotejados com aqueles verificados no TABWIN acerca do local de internação e de residência dos usuários SUS que se submeteram ao procedimento pesquisado. A fim de permitir uma análise comparativa deste processo numa perspectiva internacional, também foram levantados dados acerca da assistência hospitalar pública em saúde bucal levada a termo nos três países da América do Norte e em 31 países da Europa. Os resultados das pesquisas revelaram o caráter focalizador da atual ação da PNSB, em contraste com a atenção à saúde bucal hospitalar realizada na grande maioria dos países estudados. Entre outros resultados, as pesquisas permitiram concluir que: somente 32% dos hospitais que apresentaram AIH para os fins pesquisados possuía serviço de atenção à saúde bucal cadastrado SCNES; 1% das AIH apresentadas está relacionado ao atendimento de pacientes internados por motivos médicos; e 44% dos estados brasileiros preveem em seus instrumentos de gestão a atenção à saúde bucal em nível hospitalar. Assim, são apresentadas algumas sugestões tanto para o aperfeiçoamento da normatização da PNSB no que diz respeito à gestão da Rede de Cuidados à Pessoa com Deficiência, como para a expansão e extensão dos cuidados assistenciais em saúde bucal a todos os pacientes internados ou em tratamento ambulatorial nos hospitais do SUS.

Subnotificação da Tuberculose no Concelho da Praia no período de 2006 a 2012

Segundo a OMS, Cabo Verde possui uma importante subnotificação de tuberculose, quase metade dos casos, que é muito preocupante. Ainda assim a TUberculose é um problema de saúde pública, devido à sua elevada incidência, com tendência a aumento nos últimos anos. Essa doença é a quarta causa de óbito e sua morbidade diminui a qualidade de vida. O estudo objetiva descrever a situação de subnotificação da tuberculose no concelho da Praia no período de 2006 a 2012. A subnotificação foi avaliada com base na comparação entre o número de registros das unidades de saúde e oconsolidado enviado ao PNLTL. Também foi usado o relacionamento probabilístico entre os bancos do registro dos exames laboratoriais e do registro de hospitalização dos casos de Tuberculose. Três estratégias foram adotadas para extração de dados de acordo com os documentos disponíveis nas unidades: (i) centros de saúde; (ii) laboratórios da delegacia de saúde e do HAN e (iii) hospital (HAN). Nos centros de saúde foram extraídos dados das fichas de atendimento dos pacientes diagnosticados com TB e do livro de registros dos casos de TB. Esses documentos continham dados de identificação do paciente, dados clínicos e laboratoriais. No hospital, como não havia livro de registro de casos de TB buscou-se no arquivo nosológico pacientes . Nesses prontuários buscou-se extrair os mesmo dados que dos do centro de saúde, ou seja, dados de identificação individual, dados clínicos e laboratoriais. Nos laboratórios (HAN e Delegacia) foram extraídos dados de pacientes com resultado positivo para a TB. A análise consistiu na avaliação da qualidade dos bancos e remoção de registros duplicados por intermédio do relacionamento probabilístico. Para o relacionamento dos bancos foi empregada a função reclink usando a versão 10 do programa STATA. Foram calculadas taxas de subnotificação ou sobrenotificação para cada unidade e cada ano de estudo. O cálculo considerou a diferença entre o número de casos encontrados nos registros menos o número de casos notificados dividido pelo número de casos encontrados, expresso em percentual. Valores positivos indicam a ocorrência de subnotificação enquanto valores negativos indicam sobrenotificação. Os resultados permitiram concluir que existe importante subnotificação da tuberculose em Cabo Verde, no período 2006 a 2012. A subnotificação teve maior magnitude no hospital do que nas unidades básicas de saúde. A maior parte da subnotificação detectada nesse trabalho pode ser atribuída ao desconhecimento dos resultados de exames laboratoriais pelos profissionais responsáveis pelo diagnóstico dos casos e consequentemente por sua notificação. O maior número de casos não notificados foi encontrado na listagem de resultados de exames baciloscópicos positivos no laboratório. A segunda grande fonte de casos não notificados é o registro dos pacientes internados no HAN para tratamento da TB. Com base nesse estudo recomendamos medidas de aperfeiçoamento da vigilância epidemiológica da tuberculose em Cabo Verde.

Características microbiológicas e clínicas das infecções por Acinetobacter spp. e Pseudomonas aeruginosa em Unidade de Terapia Intensiva Cardíaca de um Hospital Universitário do Rio de Janeiro

As infecções em cirurgia cardíaca ainda apresentam um cenário importante nas infecções associadas à assistência a saúde (IAAS), favorecendo ao paciente à aquisição de infecções por micro-organimos multirreristentes. Este trabalho teve como objetivo avaliar o perfil de resistência a antimicrobianos, verificar a presença de genes que codificam as enzimas dos tipos oxacilinases e metalo-beta-lactamases e descrever as características demográficas e clínicas dos pacientes colonziados/infectados por Acinetobacter spp. e P.aeruginosa internados no Centro de Terapia Intensiva Cardíaca do HUPE no período de 2005 a 2010. A maioria das 46 amostras de Acinetobacter spp e das 35 de P.aeruginosa foram de origem respiratória seguido de sangue. A maioria das amostras de A. baumannii apresentou altos percentuais de resistência a: ceftazidina, cefepime, piperacilina-sulbactam, ciprofloxacin, ceftriaxona e CIM ≥32 μg/mL para os carbapenêmicos. Uma amostra foi resistente a Polimixina B. O gene blaOXA-23 foi detectado em 65% das amostras e uma amostra apresentou o gene blaOXA-24. Não foram detectados os genes blaOXA-58-like e blaOXA-143. Para P. aeruginosa os percentuais de resistência para todos os antimicrobianos foram inferiores a 32%. Quatro amostras apresentaram resistência intermediária a polimixina B e nenhum gene de resistência foi detectado. Os prontuários dos pacientes foram analisados a fim de associar as características clínicas com os processos infecciosos identificados e seu desfecho clínico. Na análise por tipo de micro-organismo associado ao processo infeccioso à idade acima de 70 anos, DM e uso da ventilação mecânica por tempo prolongado foi maior no grupo dos pacientes que apresentaram infecção por P.aeruginosa. O IAM, a ICC em internações anteriores e suas complicações (choque cardiogênico e arritmia) tiveram impacto na mortalidade na série de pacientes (p<0,05). A insuficiência renal entre todas as comorbidades foi à única que teve associação com a mortalidade (OR= 8,3). Não houve associação entre a mortalidade e o micro-organismo que causou a infecção (Acinetobacter spp. p=0,3 e P.aeruginosa p=0,2) ou a resistência a carbapenêmicos (p=0,5). Foram observados dois casos de mediastinte por Acinetobacter spp. e dois por P. aeruginosa sendo um achado inédito no Brasil até o momento.

Early versus delayed fixed dose combination abacavir/lamivudine/zidovudine in patients with HIV and tuberculosis in Tanzania.

Fixed dose combination abacavir/lamivudine/zidovudine (ABC/3TC/ZDV) among HIV-1 and tuberculosis (TB)-coinfected patients was evaluated and outcomes between early vs. delayed initiation were compared. In a randomized, pilot study conducted in the Kilimanjaro Region of Tanzania, HIV-infected inpatients with smear-positive TB and total lymphocyte count <1200/mm(3) were randomized to initiate ABC/3TC/ZDV either 2 (early) or 8 (delayed) weeks after commencing antituberculosis therapy and were followed for 104 weeks. Of 94 patients screened, 70 enrolled (41% female, median CD4 count 103 cells/mm(3)), and 33 in each group completed 104 weeks. Two deaths and 12 serious adverse events (SAEs) were observed in the early arm vs. one death, one clinical failure, and seven SAEs in the delayed arm (p = 0.6012 for time to first grade 3/4 event, SAE, or death). CD4 cell increases were +331 and +328 cells/mm(3), respectively. TB-immune reconstitution inflammatory syndromes (TB-IRIS) were not observed in any subject. Using intent-to-treat (ITT), missing = failure analyses, 74% (26/35) vs. 89% (31/35) randomized to early vs. delayed therapy had HIV RNA levels <400 copies/ml at 104 weeks (p = 0.2182) and 66% (23/35) vs. 74% (26/35), respectively, had HIV RNA levels <50 copies/ml (p = 0.6026). In an analysis in which switches from ABC/3TC/ZDV = failure, those receiving early therapy were less likely to be suppressed to <400 copies/ml [60% (21/35) vs. 86% (30/35), p = 0.030]. TB-IRIS was not observed among the 70 coinfected subjects beginning antiretroviral treatment. ABC/3TC/ZDV was well tolerated and resulted in steady immunologic improvement. Rates of virologic suppression were similar between early and delayed treatment strategies with triple nucleoside regimens when substitutions were allowed.

Leptospirosis among hospitalized febrile patients in northern Tanzania.

We enrolled consecutive febrile admissions to two hospitals in Moshi, Tanzania. Confirmed leptospirosis was defined as a ≥ 4-fold increase in microscopic agglutination test (MAT) titer; probable leptospirosis as reciprocal MAT titer ≥ 800; and exposure to pathogenic leptospires as titer ≥ 100. Among 870 patients enrolled in the study, 453 (52.1%) had paired sera available, and 40 (8.8%) of these met the definition for confirmed leptospirosis. Of 832 patients with ≥ 1 serum sample available, 30 (3.6%) had probable leptospirosis and an additional 277 (33.3%) had evidence of exposure to pathogenic leptospires. Among those with leptospirosis the most common clinical diagnoses were malaria in 31 (44.3%) and pneumonia in 18 (25.7%). Leptospirosis was associated with living in a rural area (odds ratio [OR] 3.4, P < 0.001). Among those with confirmed leptospirosis, the predominant reactive serogroups were Mini and Australis. Leptospirosis is a major yet underdiagnosed cause of febrile illness in northern Tanzania, where it appears to be endemic.

Variation in Inpatient Rehabilitation Utilization After Hospitalization for Burn Injury in the United States.

Approximately 45,000 individuals are hospitalized annually for burn treatment. Rehabilitation after hospitalization can offer a significant improvement in functional outcomes. Very little is known nationally about rehabilitation for burns, and practices may vary substantially depending on the region based on observed Medicare post-hospitalization spending amounts. This study was designed to measure variation in rehabilitation utilization by state of hospitalization for patients hospitalized with burn injury. This retrospective cohort study used nationally collected data over a 10-year period (2001 to 2010), from the Healthcare Cost and Utilization Project (HCUP) State Inpatient Databases (SIDs). Patients hospitalized for burn injury (n = 57,968) were identified by ICD-9-CM codes and were examined to see specifically if they were discharged immediately to inpatient rehabilitation after hospitalization (primary endpoint). Both unadjusted and adjusted likelihoods were calculated for each state taking into account the effects of age, insurance status, hospitalization at a burn center, and extent of burn injury by TBSA. The relative risk of discharge to inpatient rehabilitation varied by as much as 6-fold among different states. Higher TBSA, having health insurance, higher age, and burn center hospitalization all increased the likelihood of discharge to inpatient rehabilitation following acute care hospitalization. There was significant variation between states in inpatient rehabilitation utilization after adjusting for variables known to affect each outcome. Future efforts should be focused on identifying the cause of this state-to-state variation, its relationship to patient outcome, and standardizing treatment across the United States.

Behavior problems in children requiring inpatient rehabilitation treatment for asthma

Forty-eight asthmatic children (age 6-16 years), inpatients at the Hugh McMillan Medical Centre, were rated by their parents on their behavior using Achenbach's Child Behaviour Checklist. Completed checklists were used to determine normalized T scores for behavior syndromes, and these were compared against norms for clinically referred and nonreferred children. Behavior problems were elevated compared with nonreferred children for both boys and girls, with boys scoring at a clinical level. While many behavior problems were recognized, somatic complaints was a prominent syndrome, particularly for those in the 6-11-year age group.

Demographic and psychosocial characteristics of asthmatic children in a Canadian rehabilitation setting

This study investigated the demographic and psychosocial characteristics of patients attending a residential treatment program for children with asthma. Measures of background information and standardized psychosocial variables were administered to 54 inpatients over an 18-month period. Typically, our patients presented with moderate to severe chronic asthma, mostly diagnosed before 3 years of age and often associated with atopic dermatitis. The families exhibited normal levels of emotional bonding and flexibility in response to stress. Psychosocially, most children were experiencing behavioral and school-related problems, with 6-11-year-old boys exhibiting global social competency problems as well. Girls exhibited lower self-esteem. Locus of control was within the normal range for all age groups. Half the children had not previously attended an asthma education program and two-thirds of the family members either smoked and/or had a pet. The treatment implications of these characteristics of our asthma population were considered.
