Analyze the probability of specific survival and factors associated with the risk of death of patients with prostate cancer who received outpatient cancer treatment in the Brazilian Unified Health System, Brazil. Retrospective cohort study using the National Database of Oncology, developed through the deterministic-probabilistic pairing of health information systems: outpatient (SIA), hospital (SIH) and mortality (SIM). The probability of overall and specific survival was estimated by the time elapsed between the date of the first ambulatory treatment, from 2002 to 2003, until the patient's death or the end of the study. Fine and Gray's model of competing-risks regression was adjusted according to the variables: age of diagnostic, region of residence, tumor clinical staging, type of outpatient cancer treatment and hospitalization in the assessment of factors associated with risk of patient death. Of 16,280 patients studied, the average age was 70 years, approximately 25% died due to prostate cancer and 20% for other causes. The probability of overall survival was 0.50 (95%CI 0.49-0.52) and the specific was 0.70 (95%CI 0.69-0.71). The factors associated with the risk of patient death were: stage III (HR = 1.66; 95%CI 1.39-1.99) and stage IV (HR = 3.49; 95%CI 2.91-4.18), chemotherapy (HR = 2.34; 95%CI 1.76-3.11) and hospitalization (HR = 1.6; 95%CI 1.55-1.79). The late diagnosis of the tumor, palliative treatments, and worse medical condition were factors related to the worst survival and increased risk of death from prostate cancer patients in Brazil.

Resumo Contexto Devido à maior aplicação de exames de imagem rotineiros, especialmente nos pacientes com neoplasia para controle da doença, vem aumentando o diagnóstico de tromboembolismo pulmonar (TEP) incidental, importante fator de morbimortalidade associado. Objetivo Identificar os casos de TEP incidental em pacientes oncológicos submetidos a tomografia computadorizada (TC) de tórax, correlacionando aspectos clínicos e fatores de risco associados. Métodos Estudo retrospectivo de todos os episódios de TEP ocorridos de janeiro de 2013 a junho de 2016, com seleção dos pacientes oncológicos e divisão deles em dois grupos: com suspeita clínica e sem suspeita clínica (incidentais) de embolia pulmonar. Resultados Foram avaliados 468 pacientes com TEP no período citado. Destes, 23,1% eram oncológicos, entre os quais 44,4% apresentaram achado incidental de embolia pulmonar na TC de tórax. Não houve diferença estatística entre os grupos para sexo, idade e tabagismo. Quanto à procedência, 58,3% dos pacientes sem suspeita clínica eram de origem ambulatorial e 41,7% com suspeita de TEP vinham do pronto-socorro (p < 0,001). As neoplasias mais prevalentes foram de pulmão (17,6%), intestino (15,7%) e mama (13,0%). Aqueles com achado incidental apresentaram significativamente mais metástases, sem diferença entre os grupos para realização de quimioterapia, radioterapia ou cirurgia recente. Quanto aos sintomas apresentados, 41,9% daqueles sem suspeita clínica tinham queixas sugestivas de TEP quando realizaram o exame. Conclusão TEP incidental é frequente em pacientes oncológicos, especialmente naqueles provenientes de seguimento ambulatorial e em estágios avançados da doença. Sintomas sugestivos de TEP estavam presentes em pacientes sem suspeita clínica ao realizarem a TC de tórax. PMID:29930652

Resumo A pancreatite crônica é uma enfermidade associada a diversas complicações vasculares, como pseudocisto hemorrágico, trombose do sistema venoso portal e formações varicosas e pseudoaneurismáticas. O pseudoaneurisma de aorta abdominal secundário à pancreatite crônica é uma complicação rara, de difícil suspeição clínica, que requer tratamento complexo. A fisiopatologia dessa condição envolve a corrosão enzimática tecidual após a liberação e ativação de enzimas exócrinas proteolíticas das células acinares do pâncreas. O presente estudo relata o caso de um paciente de 52 anos, etilista crônico, internado com dor abdominal difusa, cuja propedêutica revelou se tratar de um pseudoaneurisma em aorta infrarrenal. Optou-se pelo tratamento cirúrgico convencional, levando-se em consideração a idade, as condições clínicas do paciente e a disponibilidade de endopróteses compatíveis com o diâmetro da aorta.

parâmetros do audiograma basal para verificar se a tuberculose resistente (TB-R) tem efeitos na audição, descrever as configurações dos audiogramas e determinar se há parâmetros que possam ser associados a essas configurações. Estudo prospectivo com pacientes diagnosticados com TB-R em um centro de tratamento de tuberculose no estado de Ogun, Nigéria. Os pacientes incluídos no estudo foram submetidos à audiometria de tons puros em até duas semanas após o início do tratamento (audiometria basal). Características demográficas e clínicas foram coletadas dos prontuários médicos dos pacientes para análises comparativas. A amostra final envolveu 132 pacientes. A média de idade dos pacientes foi de 34,5 ± 12,6 anos (variação, 8-82 anos), e a razão homem:mulher foi de 2:1. A maioria dos pacientes (n = 103; 78,0%) residia nos estados vizinhos e tinha história de falha de tratamento antituberculose (n = 125; 94.7%); 18 (13.6%) apresentavam status retroviral positivo. Doze pacientes (9,1%) apresentaram audiogramas normais, e 104 (78,8%) apresentaram perda auditiva neurossensorial, sendo as configurações mais comuns do tipo ascendente, em 54 (40,9%), e descendente, em 26 (19,7%). As médias de tons puros em frequências baixas (0,25-1,0 kHz) e altas (2,0-8,0 kHz) foram de 33,0 dB e 40,0 dB, respectivamente. Quanto ao grau de perda auditiva no melhor ouvido, 36 pacientes (27,3%) apresentaram audição normal, e 67 (50,8%) apresentaram perda auditiva leve (26-40 dB), enquanto 29 (21,9%) mostraram perda auditiva moderada ou grave. Entre as variáveis estudadas (idade, gênero, status retroviral, desfecho de tratamento anterior e peso na admissão), somente o gênero masculino foi associado às configurações audiométricas. Nesta amostra de pacientes com TB-R, a maioria apresentou perda auditiva neurossensorial leve e subótima bilateralmente, com configurações audiométricas ascendentes/descendentes associadas ao gênero masculino.

Terapia fibrinolítica sistêmica no tromboembolismo pulmonar

Resumo O tromboembolismo pulmonar permanece como um grande desafio terapêutico para os médicos especialistas, pois, apesar de todo investimento e desenvolvimento em seu diagnóstico, profilaxia e tratamento, essa condição continua sendo a principal causa de morte evitável em ambiente hospitalar. Ainda restam muitas dúvidas em relação a qual perfil de paciente vai se beneficiar de fato da terapia fibrinolítica sistêmica, sem ficar exposto a um grande risco de sangramento. A estratificação de risco e a avaliação do prognóstico do evento, através de escores clínicos de insuficiência ventricular direita, marcadores de dilatação e disfunção do ventrículo direito e avaliação da massa trombótica, associados ou de forma isolada, são ferramentas que podem auxiliar na identificação do paciente que irá se beneficiar dessa terapia. Os únicos consensos em relação à terapia fibrinolítica no tratamento do tromboembolismo pulmonar são: não deve ser indicada de forma rotineira; nenhum dos escores ou marcadores, isoladamente, devem justificar seu uso; e os pacientes com instabilidade hemodinâmica são os mais beneficiados. Além disto, deve-se avaliar cada caso em relação ao risco de sangramento, especialmente no sistema nervoso central. PMID:29930636

To evaluate the prevalence of pulmonary function abnormalities and to investigate the factors affecting lung function in patients treated for pulmonary tuberculosis. A total of 214 consecutive patients (132 men and 82 women; 20-82 years of age), treated for pulmonary tuberculosis and followed at a local dispensary, underwent spirometry and plethysmography at least one year after treatment. Pulmonary impairment was present in 102 (47.7%) of the 214 patients evaluated. The most common functional alteration was obstructive lung disease (seen in 34.6%). Of the 214 patients, 60 (28.0%) showed reduced pulmonary function (FEV1 below the lower limit of normal). Risk factors for reduced pulmonary function were having had culture-positive pulmonary tuberculosis in the past, being over 50 years of age, having recurrent tuberculosis, and having a lower level of education. Nearly half of all tuberculosis patients evolve to impaired pulmonary function. That underscores the need for pulmonary function testing after the end of treatment. Avaliar a prevalência de alterações da função pulmonar e investigar os fatores que afetam a função pulmonar em pacientes tratados para tuberculose pulmonar. Um total de 214 pacientes consecutivos (132 homens e 82 mulheres; 20-82 anos de idade), tratados para tuberculose pulmonar e acompanhados em um dispensário local, foi submetido a espirometria e pletismografia pelo menos um ano após o tratamento. O comprometimento pulmonar estava presente em 102 (47,7%) dos 214 pacientes avaliados. A alteração funcional mais comum foi o distúrbio ventilatório obstrutivo (observado em 34,6%). Dos 214 pacientes, 60 (28,0%) apresentaram função pulmonar reduzida (VEF1 abaixo do limite inferior de normalidade). Os fatores de risco para função pulmonar reduzida foram tuberculose pulmonar com cultura positiva no passado, idade acima de 50 anos, recidiva de tuberculose e menor nível de escolaridade.

To estimate the rates of recurrence, cure, and treatment abandonment in patients with pulmonary tuberculosis treated with a four-drug fixed-dose combination (FDC) regimen, as well as to evaluate possible associated factors. This was a retrospective observational study involving 208 patients with a confirmed diagnosis of pulmonary tuberculosis enrolled in the Hospital Tuberculosis Control Program at the Institute for Thoracic Diseases, located in the city of Rio de Janeiro, Brazil. Between January of 2007 and October of 2010, the patients were treated with the rifampin-isoniazid-pyrazinamide (RHZ) regimen, whereas, between November of 2010 and June of 2013, the patients were treated with the rifampin-isoniazid-pyrazinamide-ethambutol FDC (RHZE/FDC) regimen. Data regarding tuberculosis recurrence and mortality in the patients studied were retrieved from the Brazilian Case Registry Database and the Brazilian Mortality Database, respectively. The follow-up period comprised two years after treatment completion. The rates of cure, treatment abandonment, and death were 90.4%, 4.8%, and 4.8%, respectively. There were 7 cases of recurrence during the follow-up period. No significant differences in the recurrence rate were found between the RHZ and RHZE/FDC regimen groups (p = 0.13). We identified no factors associated with the occurrence of recurrence; nor were there any statistically significant differences between the treatment groups regarding adverse effects or rates of cure, treatment abandonment, or death. The adoption of the RHZE/FDC regimen produced no statistically significant differences in the rates of recurrence, cure, or treatment abandonment; nor did it have any effect on the occurrence of adverse effects, in comparison with the use of the RHZ regimen.

Hepatocellular carcinoma (HCC) is the most frequent type of primary liver cancer and its incidence is increasing around the world in the last decades, making it the third cause of death by cancer in the world. Hepatic resection is one of the most effective treatments for HCC with five-year survival rates from 50-70%, especially for patients with a single nodule and preserved liver function. Some studies have shown a worse prognosis for HCC patients whose etiology is viral. That brings us to the question about the existence of a difference between the various causes of HCC and its prognosis. To compare the prognosis (overall and disease-free survival at five years) of patients undergoing hepatectomy for the treatment of HCC with respect to various causes of liver disease. Was performed a review of medical records of patients undergoing hepatectomy between 2000 and 2014 for the treatment of HCC. They were divided into groups according to the cause of liver disease, followed by overall and disease-free survival analysis for comparison. There was no statistically significant difference in the outcomes of the groups of patients divided according to the etiology of HCC. Overall and disease-free survival at five years of the patients in this sample were 49.9% and 40.7%, respectively. From the data of this sample, was verified that there was no prognostic differences among the groups of HCC patients of the various etiologies. O carcinoma hepatocelular (CHC) é o mais frequente tipo de câncer primário do fígado e a sua incidência vem aumentando nas últimas décadas, tornando-o hoje a terceira causa de morte por câncer no mundo.

In the Systolic Heart Failure Treatment With the If Inhibitor Ivabradine Trial (SHIFT), heart rate (HR) reduction with ivabradine was associated with improved survival and reduced hospitalizations in patients with heart failure (HF). The mechanisms by which elevated HR increases mortality are not fully understood. To assess the relationship of baseline HR with clinical, neurohormonal and cardiac sympathetic activity in patients with chronic HF and elevated HR. Patients with chronic HF who were in sinus rhythm and had resting HR>70 bpm despite optimal medical treatment were included in a randomized, double-blind study comparing ivabradine versus pyridostigmine. This report refers to the baseline data of 16 initial patients. Baseline HR (before randomization to one of the drugs) was assessed, and patients were classified into two groups, with HR below or above mean values. Cardiac sympathetic activity was assessed by 123-iodine-metaiodobenzylguanidine myocardial scintigraphy. Mean HR was 83.5±11.5 bpm (range 72 to 104), and seven (43.7%) patients had HR above the mean. These patients had lower 6-min walk distance (292.3±93 vs 465.2±97.1 m, p=0.0029), higher values of N-Terminal-proBNP (median 708.4 vs 76.1, p=0.035) and lower late heart/mediastinum rate, indicating cardiac denervation (1.48±0.12 vs 1.74±0.09, p<0.001). Elevated resting HR in patients with HF under optimal medical treatment was associated with cardiac denervation, worse functional capacity, and neurohormonal activation. No SHIFT (Systolic Heart Failure Treatment With the If Inhibitor Ivabradine Trial, ou Estudo do Tratamento da Insuficiência Cardíaca Sistólica com o Inibidor de If Ivabradina), a redução da frequência cardíaca (FC) com ivabradina associou-se com melhor sobrevida e redução das hospitalizações em pacientes com insuficiência cardíaca (IC).

Literature shows that patients undergoing hemodialysis present poor physical conditioning and low tolerance to exercise. They may also suffer from respiratory dysfunctions. The purpose of this study was to evaluate the effects of neuromuscular electrical stimulation on pulmonary function and functional capacity of patients with chronic kidney disease on hemodialysis. Forty adult patients with chronic kidney disease on hemodialysis were prospectively studied and randomized into two groups (control n = 20 and treatment n = 20). The treatment group underwent bilateral femoral quadriceps muscles electrical stimulation for 30 minutes during hemodialysis, three times per week, for two months. The patients were evaluated by pulmonary function test, maximum respiratory pressures, maximum one-repetition test, and six-minute walk test (6MWT), before and after the treatment protocol. The treatment group presented increased maximum inspiratory (MIP) (p = 0.02) and expiratory pressures (MEP) (p < 0.0001), muscular strength in maximum one-repetition test (p < 0.001), and distance covered in the 6MWT (p = 0.03), and decreased systolic blood pressure (p < 0.001) and respiratory frequency (p < 0.001) when compared with the control group. Electrical neuromuscular stimulation had a positive impact on pulmonary function and functional capacity, leading to better physical performance in patients on hemodialysis.

We collected data through serial evaluations and telephone contact records. we studied 40 patients, with a mean age of 25.6 years, predominantly male (62.5%). The most frequent wounds were of the distal third of the lower limb (37.5%). Bone or tendon exposures occurred in 55% had and there was a 35% rate of exposed lower limb fractures. The treatments employed were skin grafting (57.5%), local fasciocutaneous flap (15%), muscle flap (12.5%), cross-leg fasciocutaneous flap, reverse sural flap (12.5%) and microsurgical flap (2.5%). Short-term evaluation showed that 35 patients had excellent or good results (87.5%), four had a regular result (10%), and one had an unsatisfactory result (2.5%). In the long term, of the 18 patients who answered the questionnaire, ten resumed walking, even with support, in the first three months after surgery (55.6%). young men involved in motorcycle accidents during leisure time represented the profile of patients with lower limb trauma requiring surgical reconstruction; the distal third of the leg was the most affected region. Grafting was the most used technique for reconstruction and postoperative functional evaluation showed that, despite complex lesions, most patients evolved with a favorable healing process and successful functional evolution. avaliar o tratamento de feridas traumáticas complexas de membros inferiores analisando suas características, tipos, condutas e evolução, com ênfase no tratamento cirúrgico. estudo prospectivo de pacientes tratados pela Cirurgia Plástica em um hospital regional do Distrito Federal no período de um ano.

Resumen Introducción el Programa Nacional de Sida garantiza el acceso universal a los antirretrovirales, aun así las personas que reciben medicamentos a través del sistema público no logran obtener una carga viral indetectable en la misma proporción que los pacientes del sistema privado. Este estudio cualitativo tiene como objeto identificar los factores asociados a la adherencia y retención en la cascada de atención de VIH de los sistemas de salud público y privado de Buenos Aires, según las percepciones de pacientes y del personal de salud. Métodos se registraron datos cualitativos de 12 entrevistas semi-estructuradas a informantes clave y 4 grupos focales de pacientes y personal de salud tanto del sistema público como privado. Se codificaron y analizaron temas predeterminados sobre adherencia, utilizando el software QRS Nvivo9® de análisis de datos cualitativos. Resultados pacientes y personal de salud de ambos sistemas coinciden en la importancia del estigma asociado al VIH, la relación médicopaciente, la comunicación entre ambos y la división de responsabilidades en relación al tratamiento como aspectos fundamentales para la adherencia y retención en la cascada de atención. Se observan diferencias entre los sistemas en la forma en que algunos de estos aspectos actúan. Las barreras estructurales se presentan como principales obstáculos del sistema público. Discusión se resalta la necesidad de intervenciones focalizadas en la díada médico-paciente que considere las particularidades de cada sistema de atención para facilitar el compromiso del paciente en la adherencia.

: to evaluate the thickness of the gastric wall at the time of intra gastric balloon (IGB) placement, at the time of its withdrawal and one month after withdrawal. : fifteen morbidly obese patients underwent the introduction of IGB under general anesthesia. In all patients, there was infusion of 500ml of distilled water in the balloon for the test. Measurements of the thickness of the gastric wall were made in the antrum, body and proximal body, using a radial echoendoscope with a frequency of 12MHz and maximum zoom, and its own balloon inflated with 5ml of distilled water. : the presence of IGB led to increased wall thickness of the gastric body by expanding the muscle layer. These changes were apparently transient, since 30 days after the balloon withdrawal there was a tendency to return of the wall thickness values ​​observed before the balloon insertion. : the use of intragastric balloon for the treatment of obesity determines transient increase in the wall thickness of the gastric body caused by expanded muscle layer. avaliar a espessura da parede gástrica no momento do posicionamento do balão intragástrico (BIG), no momento de sua retirada e um mês após a retirada. quinze pacientes obesos mórbidos foram submetidos à introdução de BIG sob anestesia geral. Em todos os pacientes foi feita infusão de 500 ml de água destilada e o balão foi insuflado com 5ml de água destilada. As medidas da espessura da parede gástrica foram feitas no antro, corpo e corpo alto utilizando-se um ecoendoscópio radial com frequência de 12MHz e zoom máximo. a presença do BIG levou ao aumento da espessura da parede do corpo gástrico pelo aumento de espessura da sua camada muscular. Estas alterações são aparentemente transitórias já que após 30 dias da retirada do balão existiu uma tendência de retorno da espessura da parede aos valores observados antes do seu posicionamento. a utilização do balão intragástrico para tratamento da obesidade determina

Resumo O tratamento tradicional da insuficiência da veia safena magna (VSM) inclui a ligadura alta na junção safeno-femoral combinada com a fleboextração. No entanto, a morbidade associada à insatisfação do paciente com esse tratamento tem conduzido ao desenvolvimento de técnicas alternativas, e a termoablação com laser endovenoso (EVLT) tornou-se uma alternativa minimamente invasiva à cirurgia. A formação de fístula arteriovenosa (FAV) durante o EVLT é extremamente rara. Neste estudo, relatamos um caso de identificação ecográfica de FAV entre um segmento da veia safena acessória lateral e a artéria femoral superficial. Optou-se inicialmente pela realização de duas tentativas de compressão com transdutor linear, sem sucesso, e alternativamente o procedimento cirúrgico foi realizado sem intercorrência e com resolução da FAV. Esse relato de caso evidencia a importância do seguimento de vigilância ecográfica após o EVLT tanto para o controle da efetividade do método como para o diagnóstico e tratamento precoce de suas complicações.

2016-01-01

Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disease characterized by the degeneration of motor neurons, which are the central nervous system cells that control voluntary muscle movements. The excessive salivation (sialorrhea) is present in approximately 50% of amyotrophic lateral sclerosis cases. Thus, some alternative therapeutic methods are sought, such as anticholinergic drugs and surgery. Recently the use of botulinum toxin applied at a midpoint of the salivary glands, often guided by ultrasound, have demonstrated positive results. The objective was to review the literature to demonstrate an alternative method to treatments of sialorrhea in patients with amyotrophic lateral sclerosis. In recent studies, the efficacy of botulinum toxin is confirmed, although new applications are required. Since the side effects are negligible, this is an alternative to treat amyotrophic lateral sclerosis, and other patients with diseases that present sialorrhea. RESUMO Esclerose lateral amiotrófica é uma doença neurodegenerativa progressiva e fatal, caracterizada pela degeneração dos neurônios motores, as células do sistema nervoso central que controlam os movimentos voluntários dos músculos. A salivação excessiva (sialorreia) está presente em cerca de 50% dos casos de esclerose lateral amiotrófica. Dessa forma, surgem medidas terapêuticas alternativas como drogas anticolinérgicas e cirurgia, e recentemente, o uso da toxina botulínica, aplicada em um ponto central das glândulas salivares, muitas vezes guiado por ultrassonografia, demostrou resultados positivos. Objetivou-se revisar a literatura no intuito de demonstrar um método alternativo aos tratamentos de sialorreia em pacientes com esclerose lateral amiotrófica. Em estudos recentes, a eficácia do tratamento com toxina botulínica foi confirmada e, mesmo requerendo novas aplicações, os efeitos colaterais são ínfimos. Ela surge então como alternativa não só ao

Resumo Contexto A cirurgia bariátrica é considerada a melhor opção para o tratamento da obesidade, cujos pacientes são considerados de alto risco para fenômenos tromboembólicos. Objetivos Comparar o uso de doses diferentes de heparina de baixo peso molecular (HBPM) na profilaxia da trombose venosa profunda (TVP) em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, alteração na dosagem do fator anti-Xa e sangramento pré ou pós-operatório. Métodos Estudo comparativo transversal em pacientes submetidos à cirurgia bariátrica distribuídos em dois grupos, que receberam doses de HBPM de 40 mg (grupo controle, GC) e 80 mg (grupo de estudo, GE). Foram avaliados por ultrassonografia vascular e dosagem de KPTT, TAP, plaquetas e fator anti-Xa. Resultados Foram avaliados 60 pacientes, sendo 34 no GC e 26 no GE. Foi observada diferença significativa somente no peso (p = 0,003) e índice de massa corporal (p = 0,018) no GE em relação ao GC. Não houve diferença na dosagem de KPTT, TAP, plaquetas e fator anti-Xa entre os grupos. Não foram detectados TVP ou sangramentos significativos em ambos os grupos. Conclusões Não houve diferença estatisticamente significativa na utilização de doses maiores de HBPM na profilaxia da TVP em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, dosagem do fator anti-Xa e sangramento pré ou pós-operatório.

Os desfechos secundários foram seus efeitos na hiperinsuflação pulmonar, na dispneia causada pelo exercício e na dispneia na vida diária. Estudo piloto randomizado cruzado e simples cego com 20 pacientes (média de idade: 60,9 ± 10,0 anos; média do VEF1: 69 ± 7% do previsto). Parâmetros espirométricos, pontuação no Transition Dyspnea Index, Tlim e dispneia aos esforços foram comparados após três semanas de cada tratamento (com uma semana de intervalo entre os tratamentos). Dezenove pacientes completaram o estudo - um foi excluído por causa de exacerbação da DPOC. A melhora no Tlim tendeu a ser maior com tiotrópio do que com indacaterol (96 ± 163 s vs. 8 ± 82 s; p = 0,06). Em comparação com os valores basais, o Tlim melhorou significativamente com tiotrópio (aumentando de 396 ± 319 s para 493 ± 347 s; p = 0,010), mas não com indacaterol (aumentando de 393 ± 246 para 401 ± 254 s; p = 0,678). Não houve diferença entre os tratamentos quanto à melhora na pontuação na escala de dispneia de Borg e na insuflação pulmonar no "isotempo" e no pico do exercício. Também não houve diferenças significativas entre os tratamentos quanto à pontuação no Transition Dyspnea Index (1,5 ± 2,1 vs. 0,9 ± 2,3; p = 0,39). Em pacientes com DPOC moderada, o tiotrópio tende a melhorar o Tlim em comparação com o indacaterol. Não houve diferenças significativas entre os tratamentos quanto a seus efeitos na insuflação pulmonar, na dispneia durante o exercício e na dispneia na vida diária. São necessários mais estudos, com um número maior de pacientes, para confirmar nossos achados e explorar explicações mecanicistas.

Splenic artery aneurysms - the most common visceral artery aneurysms - are found most often in multiparous women and in patients with portal hypertension. Indications for treatment of splenic artery aneurysm or pseudoaneurysm include specific symptoms, female gender and childbearing age, presence of portal hypertension, planned liver transplantation, a pseudoaneurysm of any size, and an aneurysm with a diameter of more than 2.5cm. Historically, the treatment of splenic artery aneurysm has been surgical ligation of the splenic artery, ligation of the aneurysm, or aneurysmectomy with or without splenectomy, depending on the aneurysm location. There are other percutaneous interventional techniques. The authors present a case of a splenic artery aneurysm in a 51-year-old woman, detected incidentally. RESUMO Aneurismas da artéria esplênica - os aneurismas arteriais viscerais mais comuns - são encontrados mais frequentemente em mulheres multíparas e em pacientes com hipertensão portal. As indicações para o seu tratamento incluem sintomas específicos, sexo feminino e idade fértil, presença de hipertensão portal, paciente em fila de transplante hepático, um pseudoaneurisma de qualquer tamanho, e um aneurisma com um diâmetro superior a 2,5cm. Historicamente, o tratamento do aneurisma da artéria esplênica tem sido a ligadura cirúrgica da artéria esplênica, a ligadura do aneurisma ou a aneurismectomia, com ou sem esplenectomia, dependendo do local do aneurisma. Existem outras técnicas intervencionistas percutâneas. Os autores apresentam o caso de um aneurisma de artéria esplênica em uma mulher de 51 anos de idade, diagnosticado incidentalmente.

To estimate the cost of hospitalization of patients with severe sepsis or septic shock admitted or diagnosed in the Urgent and Emergency sector at a university hospital and followed until the clinical outcome. An epidemiological, prospective, observational study conducted in a public hospital in southern Brazil for the period of one year (August 2013 to August 2014). Sepsis notification forms, medical records and data of the cost sector were used for the collection of clinical and epidemiological data. The sample comprised 95 patients, resulting in a total high cost of hospitalization (R$ 3,692,421.00), and an average of R$ 38,867.60 per patient. Over half of the total value of the treatment of sepsis (R$ 2,215,773.50) was assigned to patients who progressed to death (59.0%). The higher costs were related to discharge, diagnosis of severe sepsis, the pulmonary focus of infection and the age group of up to 59 years. The high cost of the treatment of sepsis justifies investments in training actions and institution of protocols that can direct preventive actions, and optimize diagnosis and treatment in infected and septic patients.

Essa associação já está bem descrita em pacientes com infeções pelo vírus da imunodeficiência humana (HIV), hepatite C ou influenza. Recentemente introduzido no continente americano, o vírus chicungunha, agente etiológico da febre de chicungunha, ainda não tem essa relação bem sedimentada, mas com o aumento progressivo de sua incidência e pelo fato dessa infecção causar, muitas vezes, uma restrição severa da locomoção por poliartralgia e uma possível lesão endotelial direta, casos de tromboembolismo venoso podem começar a ser descritos. Neste relato de caso, descrevemos um paciente que desenvolveu trombose de veia poplítea direita durante internação para tratamento de febre por infecção por vírus chicungunha e poliartralgia severa.

Introducción La encefalitis por anticuerpos contra el receptor de N-metil-D-aspartato (NMDA) es una entidad cada vez más diagnosticada en edad pediátrica. A diferencia de los adultos, en muchos casos no se asocia a tumores y las manifestaciones iniciales en niños más frecuentes son crisis convulsivas y trastornos del movimiento, mientras que en los adultos predominan las alteraciones psiquiátricas. Casos clínicos Presentamos seis casos pediátricos confirmados con anticuerpos contra la subunidad NR1 del receptor de NMDA en suero y líquido cefalorraquídeo. Cinco de los casos comenzaron con crisis convulsivas como manifestación clínica inicial antes de desarrollar el cuadro clásico de esta entidad. En todos los casos se utilizaron esteroides como primera línea de tratamiento, con los que sólo se observó control de las manifestaciones en uno, por lo que el resto de los pacientes requirió inmunomoduladores de segunda línea. Todos los pacientes recibieron metotrexato como tratamiento inmunomodulador para evitar recaídas y la evolución fue a la mejoría en todos ellos. Conclusiones En nuestra serie de pacientes con encefalitis por anticuerpos contra el receptor de NMDA, ninguno se asoció a tumores. Todos los casos recibieron metotrexato por lo menos durante un año, no observamos eventos adversos clínicos ni por laboratorio, ni hubo secuelas neurológicas ni recaídas durante el tratamiento. Aunque es una serie pequeña y es deseable incrementar el número y tiempo de evolución, consideramos el metotrexato una excelente alternativa como tratamiento inmunomodulador para esta patología.

Resumo Contexto Os aneurismas de aorta abdominal (AAAs) são os mais comuns. A incidência anual de ruptura do AAA é de oito casos por 100.000 habitantes. A detecção incidental pode beneficiar o paciente, desde que o diâmetro seja monitorado e o paciente receba o tratamento adequado. Objetivos Estimar a prevalência do diagnóstico incidental de aneurisma de aorta torácica (AAT) e de AAA em tomografias computadorizadas (TCs); avaliar a prevalência de sexo e idade dos pacientes e determinar quais as artérias acometidas e as características morfológicas dos aneurismas; determinar quais as indicações de TC mais associadas ao diagnóstico incidental de aneurismas. Métodos Estudo descritivo, retrospectivo e randomizado. Critérios de inclusão: pacientes com 50 anos ou mais submetidos a TC de tórax, abdome ou pelve. Critérios de exclusão: acompanhamento ou suspeita diagnóstica de aneurismas. Foram utilizados protocolos com questões sobre dados demográficos e anatômicos. Resultados Foram analisados 1.202 laudos radiológicos. Detectados 27 aneurismas (prevalência de 2,2%). Pacientes: 60% do sexo masculino e 40% do sexo feminino (p < 0,05). Localização: 13 casos (48,2%) na aorta ascendente (AAT); 7 (25,9%) na aorta infrarrenal (AAA); 2 (7,4%) aorta na transição toracoabdominal (ATA); 2 (7,4%) na ilíaca comum; 1 (3,7%) na ilíaca interna; 1 (3,7%) na artéria esplênica; e 1 (3,7%) na artéria renal. Conclusões A maioria dos pacientes foi do sexo masculino (60%); houve maior frequência de AAT (diâmetro médio de 4,1 cm), seguido de AAA (diâmetro médio de 4,0 cm) e ATA (diâmetro médio de 3,9 cm). A principal indicação para a realização de TC associada ao diagnóstico incidental de aneurismas foi em função de sintomas respiratórios. PMID:29930574

La expresión del repertorio de Vβ TCR se estudió por citometría de flujo multiparamétrica utilizando un arreglo de 24 diferentes anticuerpos monoclonales específicos de genes familiares para Vβ TCR. Se encontró el mismo perfil de expresión en las comparaciones entre los casos de LEG esporádico y familiar, así como en los consanguíneos sanos de las familias multicasos, que incluía una expresión incrementada de Vβ 5.2, Vβ 11 y Vβ 16, y una menor expresión de Vβ 3, Vβ4, Vβ 7.1 y Vβ 7. De manera interesante, solo Vβ 17 se expresó de modo diferente entre casos familiares y esporádicos de LEG. Igualmente, la expresión incrementada de Vβ 9 fue el distintivo entre los casos de LEG familiar (casos y consanguíneos sanos) y los controles sanos. Estos resultados refuerzan la noción de que el perfil final del repertorio Vβ TCR observado en LEG familiar y no familiar parece surgir de la interacción de factores genéticos, ambientales e inmunorreguladores, además de que pueden explicar las alteraciones inmunitarias que se observan en los consanguíneos sanos de pacientes con LEG.

The IgG4-related disease has a wide clinical spectrum where multiple organs can be affected, and the diagnosis depends on typical histopathological findings and an elevated IgG4 expression in plasma cells in the affected tissue. We describe the clinical presentation and evolution of a patient with acute tubulointerstitial nephritis, severe kidney failure and systemic manifestations such as lymphadenomegaly and chronic pancreatitis. The diagnosis was confirmed by the clinical picture and kidney and lymph node histopathology, in which immunohistochemistry of the lymphoid tissue showed policlonality and increased expression of IgG4, with a IgG4/total IgG ratio > 80%. The patient was treated with prednisone at a dose of 60 mg/day, followed by mycophenolate mofetil, and showed clinical and renal function improvement at 6 months of follow-up. The high index of suspicion of IgG4-related disease with multisystem involvement and the early treatment of this condition are essential to improve the prognosis of affected patients. Resumo A doença relacionada à IgG4 tem um espectro clínico amplo em que múltiplos órgãos podem ser afetados, e o diagnóstico depende de achados histopatológicos típicos e elevada expressão de IgG4 em plasmócitos no tecido afetado. Descrevemos o quadro clínico e a evolução de um paciente com nefrite túbulo-intersticial aguda, insuficiência renal grave e manifestações sistêmicas como linfoadenomegalias e pancreatite crônica. O diagnóstico foi confirmado pelas características clínicas e pela histopatologia renal e de linfonodo, na qual a imunohistoquímica mostrou tecido linfoide com policlonalidade e expressão aumentada de IgG4, com uma relação IgG4/IgG total > 80%. O paciente foi tratado com prednisona na dose de 60 mg/dia, seguido de micofenolato mofetil, e apresentou melhora clínica e da função renal depois de 6 meses de tratamento.

abordagem intensiva e tratamento do tabagismo engloba consultas, sessões de terapia cognitivo-comportamental em grupo e uso de medicamentos. Os custos do atendimento e gerenciamento do programa foram estimados utilizando a metodologia do microcusteio. A implementação plena do programa no município de Goiânia, Goiás, foi definida como sua expansão para suprir a demanda de todos os fumantes motivados a parar de fumar no município que seriam atendidos pelo Sistema Único de Saúde. Foram considerados custos médicos e não médicos diretos: recursos humanos, medicamentos, material de consumo, despesas gerais, transporte, viagens, eventos e custos de capital. Foram incluídos custos dos níveis federal, estadual e municipal de gestão. A perspectiva da análise foi a do Sistema Único de Saúde. Análise de sensibilidade foi realizada variando parâmetros referentes à quantidade de atividades e aos recursos utilizados. As fontes de dados incluíram uma amostra de unidades de saúde da Atenção Primária, secretarias de saúde municipal e estadual e Ministério da Saúde. Os custos foram estimados em reais (R$) para o ano de 2010. O custo do programa em Goiânia foi de R$429.079, sendo 78,0% referentes à abordagem e tratamento do tabagismo. O custo por paciente foi de R$534 e, por paciente que deixou de fumar, de R$1.435. A implementação plena do programa no município de Goiânia geraria custo de R$20,28 milhões, para atender 35.323 fumantes. O Programa de Tratamento do Tabagismo tem bom desempenho em termos de custo por paciente que deixa de fumar. Tendo em vista a carga do tabagismo no Brasil, o tratamento para cessação de fumar deve ser considerado prioritário ao se programar a alocação de recursos de saúde.

A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially arrhythmogenic method, it is safe for coronary patients without Chagas disease. For Chagas disease patients, however, the indication of DSE in clinical practice is uncertain, because of the arrhythmogenic potential of that heart disease. To assess DSE safety in Chagas disease patients with clinical suspicion of CAD, as well as the incidence of arrhythmias and adverse events during the exam. Retrospective analysis of a database of patients referred for DSE from May/2012 to February/2015. This study assessed 205 consecutive patients with Chagas disease suspected of having CAD. All of them had their serology for Chagas disease confirmed. Their mean age was 64±10 years and most patients were females (65.4%). No patient had significant adverse events, such as acute myocardial infarction, ventricular fibrillation, asystole, stroke, cardiac rupture and death. Regarding arrhythmias, ventricular extrasystoles occurred in 48% of patients, and non-sustained ventricular tachycardia in 7.3%. DSE proved to be safe in this population of Chagas disease patients, in which no potentially life-threatening outcome was found. Até poucas décadas atrás, os pacientes chagásicos eram predominantemente trabalhadores rurais, com baixo perfil de risco para doença obstrutiva coronária. Com a crescente urbanização, passaram a ter os mesmos fatores de risco para doença aterosclerótica que indivíduos não infectados. O ecocardiograma sob estresse com dobutamina (EED) é uma importante ferramenta no diagnóstico de coronariopatia. É referido, porém, como um método potencialmente arritmogênico, mas

aspirado traqueal (AT) no diagnóstico de PAVM. Estudo diagnóstico caso-controle envolvendo 45 pacientes sob ventilação mecânica. Amostras de AT foram obtidas de pacientes com e sem PAVM (casos e controles, respectivamente), e verificamos o número de bactérias revestidas com anticorpos monoclonais conjugados com FITC (IgA, IgM ou IgG) ou anticorpo polivalente conjugado com FITC. Utilizando microscopia de imunofluorescência, foi determinada a proporção de BRA em um número fixo de 80 bactérias. A mediana das proporções de BRA foi significativamente maior nos casos (n = 22) que nos controles (n = 23) - IgA (60,6% vs. 22,5%), IgM (42,5% vs. 12,5%), IgG (50,6% vs. 17,5%) e polivalente (75,6% vs. 33,8%) - p < 0,001 para todos. A acurácia dos melhores pontos de corte para o diagnostico de PAVM em relação aos BRA monoclonais e polivalentes foi > 95,0% e > 93,3%, respectivamente. O número de BRA em amostras de AT foi maior nos casos que nos controles. Nossos achados indicam que a avaliação de BRA no AT é uma ferramenta promissora para aumentar a especificidade do diagnóstico de PAVM. A técnica pode ser custo-efetiva e, portanto, útil em locais com poucos recursos, com as vantagens de minimizar resultados falso-positivos e evitar o tratamento excessivo.

The search for medical care occurred within 30 days after the onset of symptoms, in most cases. The mean total time between the onset of symptoms and the beginning of treatment ranged from 15 to 16 months, and the mean time between the search for medical care and the diagnosis was 4.78 months. The family history of cancer (p=0.008) and the implementation of preventive follow-up (p<0.001) were associated with shorter periods between the search for care and the beginning of treatment. Nausea, vomiting, hematochezia, weight loss and pain were associated with faster demand for care. the longer interval between the search for medical care and the diagnosis was possibly due to the non-association between the presented symptoms and the disease. identificar o tempo entre os sintomas, a busca por assistência e o início do tratamento em pacientes com câncer de estômago e colorretal e os fatores que interferem nesses processos. estudo descritivo correlacional, incluindo 101 pacientes com diagnóstico de câncer de estômago ou colorretal, atendidos por um hospital especializado em oncologia. dos 101 pacientes investigados, houve predomínio do sexo masculino, média de idade de 61,7 anos.

Next, the benefits of liver resection in the presence of extra-hepatic disease were debated, as soon as, the best sequence of treatment. Conversion chemotherapy in the presence of unresectable liver disease was also discussed in this module. Lastly, the approach to the unresectable disease was also discussed, focusing in the best chemotherapy regimens and hole of chemo-embolization. RESUMO Neste último módulo do consenso, abordou-se alguns temas controversos. O primeiro tópico discutido foi o manejo da doença após progressão na primeira linha de quimioterapia, com foco em se ainda haveria indicação cirúrgica neste cenário. A seguir, o painel debruçou-se sobre as situações de ressecção da doença hepática na presença de doença extra-hepática, assim como, qual a melhor sequência de tratamento. O tratamento de conversão para doença inicialmente irressecável também foi abordado neste módulo, incluindo as importantes definições de quando se pode esperar que a doença se torne ressecável e quais esquemas terapêuticos seriam mais efetivos à luz dos conhecimentos atuais sobre a biologia tumoral e taxas de resposta objetiva. Por último, o tratamento da doença não passível de ressecção foi discutida, focando-se nos melhores esquemas a serem empregados e seu sequenciamento, bem como o papel da quimioembolização no manejo destes pacientes.

Métodos: Foram incluídos cem pacientes adultos sem doenças cardíacas ou pulmonares conhecidas que procuraram atendimento de urgência com queixas cardiológicas. Foram excluídos pacientes com alterações isquêmicas no eletrocardiograma ou febre. A ecocardiografia direcionada foi realizada logo após a avaliação inicial do paciente na sala de emergência, com aparelho ultraportátil GE Vscan, avaliando subjetivamente: dimensões das cavidades, função sistólica ventricular, fluxos intracardíacos pelo mapeamento de fluxo em cores, pericárdio e aorta. Resultados: A idade média dos pacientes foi 61 ± 17 anos. O quadro clínico inicial foi dor torácica (52 pacientes), dispneia (32 pacientes), arritmia/avaliação da função ventricular (dez pacientes), hipotensão/tontura (cinco pacientes) e edema periférico (um paciente). Em 28 pacientes a ecocardiografia direcionada confirmou a hipótese diagnóstica inicial: 19 pacientes com insuficiência cardíaca, cinco com síndrome coronariana aguda, dois com tromboembolismo pulmonar e dois com tamponamento cardíaco. Em 17 pacientes, a ecocardiografia direcionada alterou o diagnóstico, afastando a hipótese clínica inicial em dez casos com suspeita de insuficiência cardíaca, dois com suspeita de tromboembolismo pulmonar, dois com hipotensão a esclarecer, e em cada um dos três restantes com suspeitas de síndrome coronariana aguda, tamponamento cardíaco e dissecção de aorta. Conclusão: A ecocardiografia direcionada ultraportátil em serviço de emergências clínicas pode definir rapidamente o diagnóstico e, com isso, é possível iniciar mais precocemente o tratamento adequado.

to present our experience in the surgical treatment of extensive skullcap defects with customized acrylic implants. we conducted a retrospective analysis of patients with extensive skull defects undergoing acrylic cranioplasties between 2004 and 2013. We carefully selected all patients and classified surgical results based on three scales (craniofacial esthetics, improvement of facial symmetry and need for additional surgery). fifteen patients underwent cranioplasty with intraoperative acrylic implants, whether manually customized (46.67%) or made with prototyped three-dimensional biomodels (53.33%). There were two (13.33%) complications (one infection with implant withdrawal and one seroma). We considered the craniofacial aesthetics excellent (50%), the degree of improvement of craniofacial symmetry satisfactory (57.14%), and the overall mean of surgical results according to the need for new surgeries was 1.5±0.52. cranioplasties of patients with extensive skullcap defects should obey careful and predetermined criteria, both for selection and for the acrylic implant customization method. apresentar nossa experiência no tratamento cirúrgico dos defeitos extensos da calota craniana com implantes de acrílico customizados. análise retrospectiva de pacientes com defeitos extensos da calota craniana submetidos à cranioplastias com acrílico entre 2004 e 2013.

To determine whether M-SOB effects in such chronic diseases as MS can be experimentally modeled, we examined the effect of M-SOB on susceptibility of C57BL/6J mice to experimental autoimmune encephalomyelitis (EAE). As in MS, mice that were born during the M-SOB with the lowest birth rate were less susceptible to EAE than mice born during the M-SOB with the highest birth rate. We also show that the M-SOB effect on EAE susceptibility is associated with differential production of multiple cytokines/chemokines by neuroantigen-specific T cells that are known to play a role in EAE pathogenesis. Taken together, these results support the existence of an M-SOB effect that may reflect seasonally dependent developmental differences in adaptive immune responses to self-antigens independent of external stimuli, including exposure to sunlight and vitamin D. Moreover, our documentation of an M-SOB effect on EAE susceptibility in mice allows for modeling and detailed analysis of mechanisms that underlie the M-SOB effect in not only MS but in numerous other diseases in which M-SOB impacts susceptibility.-Reynolds, J.

Biological treatment of sulfate-laden wastewater consists of two separate reactors to reduce sulfate to sulfide by sulfate-reducing bacteria (SRB) and to oxidize sulfide to sulfur (S(0)) by sulfide oxidation bacteria (SOB). To have SRB+SOB in a single reactor faced difficulty of low S(0) conversion. This study for the first time revealed that dissolved oxygen (DO) level can be used to manipulate SRB+SOB reactions in a single reactor. This work demonstrated successful operation of an integrated SRB+SOB reactor under micro-aerobic condition. At DO = 0.10-0.12 mg l(-1), since the activities of SOB were enhanced by limited oxygen, the removal efficiency for sulfate reached 81.5% and the recovery of S(0) peaked at 71.8%, higher than those reported in literature. At increased DO, chemical oxidation of sulfide with molecular oxygen competed with SOB so conversion of S(0) started to decline. At DO>0.30 mg l(-1) activities of SRB were inhibited, leading to failure of the SRB+SOB reactor. Copyright © 2012 Elsevier Ltd. All rights reserved.

cenário dessa doença, com aumento expressivo da sobrevida e qualidade de vida. Atualmente, o Brasil dispõe de um programa de ampla cobertura para a triagem neonatal de FC e centros de referência distribuídos na maior parte desses estados para seguimento dos indivíduos. Antigamente confinada à faixa etária pediátrica, tem-se observado um aumento de pacientes adultos com FC tanto pelo maior número de diagnósticos de formas atípicas, de expressão fenotípica mais leve, assim como pelo aumento da expectativa de vida com os novos tratamentos. Entretanto, ainda se observa uma grande heterogeneidade no acesso aos métodos diagnósticos e terapêuticos para FC entre as diferentes regiões brasileiras. O objetivo dessas diretrizes foi reunir as principais evidências científicas que norteiam o manejo desses pacientes. Um grupo de 18 especialistas em FC elaborou 82 perguntas clínicas relevantes que foram divididas em cinco categorias: características de um centro de referência; diagnóstico; tratamento da doença respiratória; tratamento gastrointestinal e nutricional; e outros aspectos. Diversos profissionais brasileiros atuantes na área da FC foram convidados a responder as perguntas formuladas pelos coordenadores. A literatura disponível foi pesquisada na base de dados PubMed com palavras-chave, buscando-se as melhores respostas às perguntas dos autores.

ão arterial sistêmica secundária, associa-se ainda à fibrilação atrial, acidente vascular encefálico e doença arterial coronariana, aumentando a morbidade e mortalidade cardiovascular. O tratamento da AOS com pressão positiva contínua em vias aéreas não é tolerado por todos os pacientes e, muitas vezes, não é indicado para formas leves. Daí, métodos alternativos de tratamento da AOS e de suas consequências cardiovasculares são necessários. A prática usual de exercícios físicos promove benefícios adicionais à redução do peso em pacientes com AOS; contudo, os mecanismos ainda são incertos. Entre as adaptações fisiológicas proporcionadas pelo exercício físico nessa população destacam-se o aumento do tônus da musculatura dilatadora das vias aéreas superiores e do tempo do estágio do sono de ondas lentas e a redução do acúmulo cervical de líquido, da resposta inflamatória sistêmica e do peso corpóreo. Os principais benefícios de programas de exercício físico para essa população incluem a redução da gravidade da AOS e da sonolência diurna e o aumento da eficiência do sono e consumo máximo de oxigênio. Poucos estudos avaliaram o papel do exercício físico realizado de forma isolada no tratamento da AOS, além de existirem muitas diferenças relacionadas aos protocolos de exercício utilizados. Entretanto, o emprego de exercícios aeróbios isolados ou combinados aos exercícios resistidos é um ponto comum entre os estudos. Nessa revisão, os principais estudos e mecanismos envolvidos no tratamento da AOS por meio da realização de exercícios físicos são apresentados. Além dos benefícios clínicos sistêmicos proporcionados pelo exercício físico, pacientes com AOS submetidos a um programa regular de exercícios predominantemente aeróbicos, apresentam redução da gravidade da doença e da sonolência diurna, aumento da eficiência do sono e do pico de consumo de oxigênio, independentemente da perda de peso.

Os pontos de divergência entre especialistas incluem questões como: quais pacientes devem receber TXA no trauma? O tratamento deve ser realizado em ambiente pré-hospitalar? Há necessidade de exames laboratoriais para indicar o tratamento? Qual o perfil de segurança da droga? A principal questão para a qual ainda não existe qualquer embasamento na literatura é: qual a indicação do tratamento dentro de protocolos de transfusão maciça? Responder às questões propostas, com base em avaliação crítica da evidência reunida até o momento e realizar estudo de custo-efetividade do uso do TXA no trauma adaptado à realidade brasileira. Foi realizada revisão da literatura através de estratégia de busca: PubMed.com, Embase e no Cab Abstract pelos descritores "tranexamic AND trauma", em todos idiomas, resultando em 426 artigos. Foram excluídos aqueles relativos às operações eletivas, restando 79 artigos. Cinquenta e cinco foram selecionados e avaliados criticamente com vistas a responder às questões em estudo. A avaliação de custo-efetividade foi realizada utilizando dados do estudo CRASH-2 e populacionais oficiais brasileiros. Através da análise da evidência disponível chegou-se à conclusão de que o ácido tranexâmico é tratamento eficaz e efetivo, devendo ser administrado à ampla gama de pacientes, incluindo todos aqueles com indicação já avaliada nos protocolos de pesquisa publicados e provavelmente devam-se expandir os critérios de indicação. Quanto à avaliação de custo-efetividade, o TXA mostrou-se bastante custo-eficaz com gasto médio de R$ 61,35 por ano de vida salvo. O uso do ácido tranexâmico no trauma parece ser eficaz, efetivo e custo-eficaz nos diversos grupos de pacientes politraumatizados. Seu uso em protocolos de transfusão maciça ainda deve ser objeto de futuras investigações.

Season of birth bias in eating disorders--fact or fiction?

PubMed

Winje, Eirin; Willoughby, Kate; Lask, Bryan

2008-09-01

A season of birth (SoB) bias is said to be present if the SoB pattern for a particular group varies from the pattern within the normal population. Significant biases have been found for several disorders including eating disorders (EDs). This article critically reviews the existing literature on SoB in ED in order to inform future hypothesis-based research. A literature search identified 12 papers investigating SoB in ED. Despite methodological differences, the studies consistently show a SoB bias for anorexia nervosa (AN) in the spring months, in both the northern and southern Hemispheres. This is especially strong for early-onset and restrictive subtype of AN. These findings suggest that SoB is a risk factor for AN. However, none of the studies have been methodologically satisfactory. Future research needs to overcome numerous methodological challenges and to explore specific hypotheses to explain this bias. (c) 2008 by Wiley Periodicals, Inc.

In the last few years, new primary immunodeficiencies and genetic defects have been described. Recently, immunoglobulin products with improved compositions and for subcutaneous use have become available in Brazil. In order to guide physicians on the use of human immunoglobulin to treat primary immunodeficiencies, based on a narrative literature review and their professional experience, the members of the Primary Immunodeficiency Group of the Brazilian Society of Allergy and Immunology prepared an updated document of the 1st Brazilian Consensus, published in 2010. The document presents new knowledge about the indications and efficacy of immunoglobulin therapy in primary immunodeficiencies, relevant production-related aspects, mode of use (routes of administration, pharmacokinetics, doses and intervals), adverse events (major, prevention, treatment and reporting), patient monitoring, presentations available and how to have access to this therapeutic resource in Brazil.

Resumo A síndrome antifosfolipíde (SAF) é uma doença autoimune sistêmica caracterizada por trombose arterial ou venosa recorrente e/ou morbidade gestacional e pela presença dos anticorpos antifosfolipídeos, podendo apresentar outras manifestações vasculares, como microangiopatia, arteriopatia crônica e SAF catastrófica. Determinados testes laboratoriais para a síndrome (por exemplo, o anticoagulante lúpico) podem sofrer interferência do uso de medicações anticoagulantes, dificultando o diagnóstico. A fisiopatologia da SAF é complexa, sendo enumerados no texto diversos mecanismos patogênicos relacionados à coagulação, ao endotélio e às plaquetas. Por fim, discutimos o tratamento da SAF de acordo com a presença e o tipo de manifestações clínicas, o uso dos anticoagulantes orais diretos e o manejo perioperatório de pacientes com SAF.

Prediction of individual season of birth using MRI.

Previous research suggests statistical associations between season of birth (SOB) with prevalence of neurobehavioral disorders such as schizophrenia and bipolar disorder, personality traits such as novelty and sensation seeking, and suicidal behavior. These effects are thought to be mediated by seasonal differences in perinatal photoperiod, which was recently shown to imprint circadian clock neurons and behavior in rodents. However, it is unknown whether SOB is associated with any measurable differences in the normal human adult brain, and whether individual SOB can be deduced based on phenotype. Here I show that SOB predicts morphological differences in brain structure, and that MRI scans carry spatially distributed information allowing significantly above chance prediction of an individual's SOB. Using an open source database of over 550 structural brain scans, Voxel-Based Morphometry (VBM) analysis showed a significant SOB effect in the left superior temporal gyrus (STG) in males (p=0.009, FWE whole-brain corrected), with greater gray matter volumes in fall and winter births. A cosinor analysis revealed a significant annual periodicity in the left STG gray matter volume (Zero Amplitude Test: p<5×10(-7)), with a peak towards the end of December and a nadir towards the end of June, suggesting that perinatal photoperiod accounts for this SOB effect. Whole-brain VBM maps were used as input features to multivariate machine-learning based analyses to classify SOB. Significantly greater than chance prediction was achieved in females (overall accuracy 35%, p<0.001), but not in males (overall accuracy 26%, p=0.45). Pairwise binary classification in females revealed that the highest discrimination was obtained for winter vs. summer classification (peak area under the ROC curve=0.71, p<0.0005). Discriminating regions included fusiform and middle temporal gyrus, inferior and superior parietal lobe, cerebellum, and dorsolateral and dorsomedial prefrontal cortex. Results

A novel toxicity detection methodology based on sulfur-oxidizing bacteria (SOB) has been developed for the rapid and reliable detection of toxic chemicals in water. The methodology exploits the ability of SOB to oxidize sulfur particles in the presence of oxygen to produce sulfuric acid. The reaction results in an increase in electrical conductivity (EC) and a decrease in pH. The assay is based on the inhibition of SOB in the presence of toxic chemicals by measuring changes in EC and pH. We found that SOB biosensor can detect toxic chemicals, such as heavy metals and CN-, in the 5-2000ppb range. One bacterium was isolated from an SOB biosensor and the 16S rRNA gene of the bacterial strain has 99% and 96% sequence similarity to Acidithiobacillus sp. ORCS6 and Acidithiobacillus caldus DSM 8584, respectively. The isolate was identified as A. caldus SMK. The SOB biosensor is ideally suited for monitoring toxic chemicals in water having the advantages of high sensitivity and quick detection.

To describe diagnostic and treatment aspects of hard metal lung disease (HMLD) and to review the current literature on the topic. This was a retrospective study based on the medical records of patients treated at the Occupational Respiratory Diseases Clinic of the Instituto do Coração, in the city of São Paulo, Brazil, between 2010 and 2013. Of 320 patients treated during the study period, 5 (1.56%) were diagnosed with HMLD. All of those 5 patients were male (mean age, 42.0 ± 13.6 years; mean duration of exposure to hard metals, 11.4 ± 8.0 years). Occupational histories were taken, after which the patients underwent clinical evaluation, chest HRCT, pulmonary function tests, bronchoscopy, BAL, and lung biopsy. Restrictive lung disease was found in all subjects. The most common chest HRCT finding was ground glass opacities (in 80%). In 4 patients, BALF revealed multinucleated giant cells. In 3 patients, lung biopsy revealed giant cell interstitial pneumonia. One patient was diagnosed with desquamative interstitial pneumonia associated with cellular bronchiolitis, and another was diagnosed with a hypersensitivity pneumonitis pattern. All patients were withdrawn from exposure and treated with corticosteroid. Clinical improvement occurred in 2 patients, whereas the disease progressed in 3. Although HMLD is a rare entity, it should always be included in the differential diagnosis of respiratory dysfunction in workers with a high occupational risk of exposure to hard metal particles. A relevant history (clinical and occupational) accompanied by chest HRCT and BAL findings suggestive of the disease might be sufficient for the diagnosis.

Identifying the predictors of hope in patients with breast cancer during chemotherapy treatment. A prospective longitudinal study. The sample was composed of 122 women who responded to the instruments of hope, anxiety and depression, coping, fatigue, religiosity and self-esteem in the first and last cycle of chemotherapy. These variables were used in adjusting the logistic regression model that characterized multivariate statistics, allowing identification of predictor variables. The increase of hope at the end of chemotherapy treatment was statistically significant (p = 0.012). The delay in undergoing treatment from the onset of breast cancer symptoms, Karnofsky Performance Status, depression, self-esteem and pain were characterized as factors being associated to hope by univariate analysis. Among the variables analyzed, pain was the only predicting factor of hope. Pain was the predicting factor in this sample. Hope increased during treatment and revealed the following associated factors: Karnofsky Performance Status, delay in starting the treatment, depression, self-esteem and pain. This study brought forth a multidisciplinary contribution, allowing for understanding the factors that can influence hope and presenting support to nursing care. The data evidenced conditions of improvement or worsening of hope, which requires interdisciplinary attention in Oncology.

objetivo foi determinar como crianças e adolescentes asmáticas de baixa renda no Brasil são distribuídos através de uma análise de clusters. Foram incluídos 306 crianças e adolescentes (6-18 anos de idade) com diagnóstico clínico de asma e sob tratamento médico por pelo menos um ano de acompanhamento. No momento da inclusão, todos os pacientes estavam clinicamente estáveis. Vinte variáveis comumente determinadas na prática clínica e consideradas importantes na definição dos fenótipos de asma foram selecionadas para a análise de clusters. As variáveis com alta multicolinearidade foram excluídas. Uma análise de clusters foi realizada utilizando-se um teste aglomerativo em duas etapas e log-likelihood distance measure. Três clusters foram definidos para nossa população. O cluster 1 (n = 94) incluiu indivíduos com função pulmonar normal, inflamação eosinofílica leve, poucas exacerbações, início mais tardio da asma e atopia leve. O cluster 2 (n = 87) incluiu pacientes com função pulmonar normal, número moderado de exacerbações, início precoce da asma, inflamação eosinofílica mais grave e atopia moderada. O cluster 3 (n = 108) incluiu pacientes com função pulmonar ruim, exacerbações frequentes, inflamação eosinofílica e atopia graves. A asma foi caracterizada por presença de atopia, número de exacerbações e função pulmonar em crianças e adolescentes de baixa renda no Brasil. As muitas semelhanças entre esta e outras análises de clusters de fenótipos indicam que essa abordagem apresenta boa generalização.

This study investigated the diversity and quantitative shifts of sulfur-oxidizing bacteria (SOB) during the onset of black band disease (BBD) in corals using quantitative PCR (qPCR) and cloning approaches targeting the soxB gene, involved in sulfur oxidation. Four Montipora sp. coral colonies identified with lesions previously termed cyanobacterial patches (CP) (comprising microbial communities different from those of BBD lesions), was monitored in situ as CP developed into BBD. The overall abundance of SOB in both CP and BBD lesions were very low and near the detection limit of the qPCR assay, although consistently indicated that SOB populations decreased as the lesions transitioned from CP to BBD. Phylogenetic assessment of retrieved soxB genes showed that SOB in both CP and BBD lesions were dominated by one sequence type, representing > 70% of all soxB gene sequences and affiliated with members of the Rhodobacteraceae within the α-Proteobacteria. This study represents the first assessment targeting SOB within BBD lesions and clearly shows that SOB are not highly diverse or abundant in this complex microbial mat. The lack of oxidation of reduced sulfur compounds by SOB likely aids the accumulation of high levels of sulfide at the base of the BBD mat, a compound contributing to the pathogenicity of BBD lesions. © 2013 John Wiley & Sons Ltd and Society for Applied Microbiology.

Resumo Contexto Faz-se importante o conhecimento técnico dos ajustes de potência e de densidade de energia linear endovenosa (linear endovenous energy density, LEED) adequados para atingir o objetivo final da termoablação endovenosa (endovenous laser ablation, EVLA). Objetivos Avaliar a influência de diferentes LEEDs em termos de patência e presença de refluxo, bem como determinar a evolução clínica. Métodos Foram incluídas 60 veias safenas magnas (VSM). Os pacientes foram randomizados em dois grupos: EVLA com baixa potência (7 W e LEED de 20-40 J/cm) e com alta potência (15 W e LEED de 80-100 J/cm). O acompanhamento com eco-Doppler e escore de severidade clínica venoso (VCSS) foi realizado nos intervalos de 3-5 dias, 30 dias, 180 dias e 1 ano após o procedimento. Resultados Dezoito pacientes (29 membros) tratados com 7W de potência e 13 pacientes (23 membros) com 15 W completaram o estudo. Não houve diferença significativa considerando idade, tempo de cirurgia e o uso de analgésicos, lateralidade, gênero e presença de comorbidades. O LEED médio foi de 33,54 J/cm no grupo de 7 W e de 88,66 J/cm no de 15 W. Ambos apresentaram melhora no VCSS, redução significativa dos diâmetros da JSF e ausência de diferença significativa quanto ao aumento do comprimento do coto da VSM e de refluxo após o tratamento. Conclusões A utilização de maior densidade de energia mostrou-se mais efetiva em relação à estabilização do comprimento do coto da VSM e do refluxo em 6 meses. Fazem-se necessários estudos com um período de acompanhamento maior para fundamentar essa hipótese. PMID:29930650

To evaluate the costs of a topical treatment of pressure ulcer (PU) patients in a hospital unit for treatment of chronic patients in 2014. This is an activity-based costing study. This method encompasses the identification, measurement and pricing of physical and human resources consumed for dressings. Procedure costs varied between BRL 16.41 and BRL 260.18. For PUs of the same category, of near areas and with the same type of barrier/adjuvant, the cost varied between 3.5% and 614.6%. For most dressings, the cost increased proportionally to the increase of the area and to the development of PU category. The primary barrier accounted for a high percentage of costs among all items required to the application of dressings (human and material resources). Dressings applied in sacral PUs had longer application times. This study allowed us to understand the costs involved in the treatment of PUs, and it may support decision-makers and other cost-effectiveness studies.

Sulfate-reducing bacteria (SRB) have been studied extensively in the petroleum industry due to their role in corrosion, but very little is known about sulfur-oxidizing bacteria (SOB), which drive the oxidization of sulfur-compounds produced by the activity of SRB in petroleum reservoirs. Here, we surveyed the community structure, diversity and abundance of SRB and SOB simultaneously based on 16S rRNA, dsrB and soxB gene sequencing, and quantitative PCR analyses, respectively in petroleum reservoirs with different physicochemical properties. Similar to SRB, SOB were found widely inhabiting the analyzed reservoirs with high diversity and different structures. The dominant SRB belonged to the classes Deltaproteobacteria and Clostridia, and included the Desulfotignum, Desulfotomaculum, Desulfovibrio, Desulfobulbus, and Desulfomicrobium genera. The most frequently detected potential SOB were Sulfurimonas, Thiobacillus, Thioclava, Thiohalomonas and Dechloromonas, and belonged to Betaproteobacteria, Alphaproteobacteria, and Epsilonproteobacteria. Among them, Desulfovibrio, Desulfomicrobium, Thioclava, and Sulfurimonas were highly abundant in the low-temperature reservoirs, while Desulfotomaculum, Desulfotignum, Thiobacillus, and Dechloromonas were more often present in high-temperature reservoirs. The relative abundances of SRB and SOB varied and were present at higher proportions in the relatively high-temperature reservoirs. Canonical correspondence analysis also revealed that the SRB and SOB communities in reservoirs displayed high niche specificity and were closely related to reservoir temperature, pH of the formation brine, and sulfate concentration. In conclusion, this study extends our knowledge about the distribution of SRB and SOB communities in petroleum reservoirs. PMID:28210252

Background Season of birth (SOB) has been associated with many physiological and psychological traits including novelty seeking and sensation seeking. Similar traits have been associated with genetic polymorphisms in the dopamine system. SOB and dopamine receptor genetic polymorphisms may independently and interactively influence similar behaviors through their common effects on the dopaminergic system. Methodology/Principal Findings Based on a sample of 195 subjects, we examined whether SOB was associated with impulsivity, sensation seeking and reproductive behaviors. Additionally we examined potential interactions of dopamine receptor genes with SOB for the same set of traits. Phenotypes were evaluated using the Sociosexual Orientation Inventory, the Barratt Impulsivity Scale, the Eysenck Impulsivity Questionnaire, the Sensation Seeking Scale, and the Delay Discounting Task. Subjects were also asked about their age at first sex as well as their desired age at the birth of their first child. The dopamine gene polymorphisms examined were Dopamine Receptor D2 (DRD2) TaqI A and D4 (DRD4) 48 bp VNTR. Primary analyses included factorial gender×SOB ANOVAs or binary logistic regression models for each dependent trait. Secondary analysis extended the factorial models by also including DRD2 and DRD4 genotypes as independent variables. Winter-born males were more sensation seeking than non-winter born males. In factorial models including both genotype and season of birth as variables, two previously unobserved effects were discovered: (1) a SOB×DRD4 interaction effect on venturesomeness and (2) a DRD2×DRD4 interaction effect on sensation seeking. Conclusion These results are consistent with past findings that SOB is related to sensation seeking. Additionally, these results provide tentative support for the hypothesis that SOB modifies the behavioral expression of dopaminergic genetic polymorphism. These findings suggest that SOB should be included in future studies of

Comparison of the Structure and Expression of Odd-Skipped and Two Related Genes That Encode a New Family of Zinc Finger Proteins in Drosophila

The odd-skipped (odd) gene, which was identified on the basis of a pair-rule segmentation phenotype in mutant embryos, is initially expressed in the Drosophila embryo in seven pair-rule stripes, but later exhibits a segment polarity-like pattern for which no phenotypic correlate is apparent. We have molecularly characterized two embryonically expressed odd-cognate genes, sob and bowel (bowl), that encode proteins with highly conserved C(2)H(2) zinc fingers. While the Sob and Bowl proteins each contain five tandem fingers, the Odd protein lacks a fifth (C-terminal) finger and is also less conserved among the four common fingers. Reminiscent of many segmentation gene paralogues, the closely linked odd and sob genes are expressed during embryogenesis in similar striped patterns; in contrast, the less-tightly linked bowl gene is expressed in a distinctly different pattern at the termini of the early embryo. Although our results indicate that odd and sob are more likely than bowl to share overlapping developmental roles, some functional divergence between the Odd and Sob proteins is suggested by the absence of homology outside the zinc fingers, and also by amino acid substitutions in the Odd zinc fingers at positions that appear to be constrained in Sob and Bowl.

Assessment of the stoichiometry and efficiency of CO2 fixation coupled to reduced sulfur oxidation

Chemolithoautotrophic sulfur oxidizing bacteria (SOB) couple the oxidation of reduced sulfur compounds to the production of biomass. Their role in the cycling of carbon, sulfur, oxygen, and nitrogen is, however, difficult to quantify due to the complexity of sulfur oxidation pathways. We describe a generic theoretical framework for linking the stoichiometry and energy conservation efficiency of autotrophic sulfur oxidation while accounting for the partitioning of the reduced sulfur pool between the energy generating and energy conserving steps as well as between the main possible products (sulfate vs. zero-valent sulfur). Using this framework, we show that the energy conservation efficiency varies widely among SOB with no apparent relationship to their phylogeny. Aerobic SOB equipped with reverse dissimilatory sulfite reductase tend to have higher efficiency than those relying on the complete Sox pathway, whereas for anaerobic SOB the presence of membrane-bound, as opposed to periplasmic, nitrate reductase systems appears to be linked to higher efficiency. We employ the framework to also show how limited rate measurements can be used to estimate the primary productivity of SOB without the knowledge of the sulfate-to-zero-valent-sulfur production ratio. Finally, we discuss how the framework can help researchers gain new insights into the activity of SOB and their niches. PMID:26052315

Resumen Introducción: Los meningiomas Grado II tienen un comportamiento biológico más agresivo que los Grado I. A partir del año 2007, con los nuevos criterios de clasificación, la incidencia de meningiomas atípicos reportada aumentó hasta un 35%. Objetivo: Establecer diferencias entre los Meningiomas Grado I y II de la clasificación de la OMS, en lo que respecta a: grados de resección de Simpson, localización tumoral, necesidad de reintervención, tratamiento adyuvante, evolución y mortalidad. Métodos: Estudio retrospectivo de 63 pacientes operados entre el periodo 2009-2015. Variables analizadas: sexo, edad, grado histológico, localización, grado de resección quirúrgica, radioterapia adyuvante, mortalidad y evolución. Resultados: Se analizaron 63 pacientes: 51 Grado I y 12 Grado II de la clasificación de la OMS. La distribución por sexo no mostró diferencias entre meningiomas benignos y atípicos. Tampoco el grupo etario de presentación; mediana de 57 años. Un 55% de los meningiomas benignos se localizaron fuera de la base del cráneo versus el 91,6% de los meningiomas atípicos (P = 0.02). En el 74,5% de los meningiomas benignos se logró una resección total (Simpson I-II-III) versus el 58.3% para los atípicos (P = 0.3). Se reintervinieron el 33,3% de meningiomas atípicos en comparación con el 9.8% de los benignos (P = 0.03). Tuvieron una buena evolución el 86,2% de los benignos vs el 53,8% de los GII (P = 0.01). Realizaron radioterapia adyuvante el 33,3% de los meningiomas Grado II vs el 1,9% de los Grado I. Conclusiones: Los meningiomas atípicos cerebrales tienen peor pronóstico evolutivo que los Grado I de la OMS. Presentan una mayor tasa de reintervención y se localizan más frecuentemente fuera de la base del cráneo. La localización pareciera ser un factor de riesgo para el desarrollo de meningiomas atípicos.

Sulphur-oxidising bacteria (SOB) play a key role in the biogeochemical cycling of sulphur in soil ecosystems. However, the ecology of SOB is poorly understood, and there is little knowledge about the taxa capable of sulphur oxidation, their distribution, habitat preferences and ecophysiology. Furthermore, as yet there are no conclusive links between SOB community size or structure and rates of sulphur oxidation. We have developed a molecular approach based on primer design targeting the soxB functional gene of nonfilamentous chemolithotrophic SOB that allows assessment of both abundance and diversity. Cloning and sequencing revealed considerable diversity of known soxB genotypes from agricultural soils and also evidence for previously undescribed taxa. In a microcosm experiment, abundance of soxB genes increased with sulphur oxidation rate in soils amended with elemental sulphur. Addition of elemental sulphur to soil had a significant effect in the soxB gene diversity, with the chemolithotrophic Thiobacillus-like Betaproteobacteria sequences dominating clone libraries 6 days after sulphur application. Using culture-independent methodology, the study provides evidence for links between abundance and diversity of SOB and sulphur oxidation. The methodology provides a new tool for investigation of the ecology and role of SOB in soil sulphur biogeochemistry. © 2014 Federation of European Microbiological Societies.

Sulfur-reducing bacteria (SRB) and sulfur-oxidizing bacteria (SOB) play essential roles in marine sponges. However, the detailed characteristics and physiology of the bacteria are largely unknown. Here, we present and analyse the first genome of sponge-associated SOB using a recently developed metagenomic binning strategy. The loss of transposase and virulence-associated genes and the maintenance of the ancient polyphosphate glucokinase gene suggested a stabilized SOB genome that might have coevolved with the ancient host during establishment of their association. Exclusive distribution in sponge, bacterial detoxification for the host (sulfide oxidation) and the enrichment for symbiotic characteristics (genes-encoding ankyrin) in the SOB genome supported the bacterial role as an intercellular symbiont. Despite possessing complete autotrophic sulfur oxidation pathways, the bacterium developed a much more versatile capacity for carbohydrate uptake and metabolism, in comparison with its closest relatives (Thioalkalivibrio) and to other representative autotrophs from the same order (Chromatiales). The ability to perform both autotrophic and heterotrophic metabolism likely results from the unstable supply of reduced sulfur in the sponge and is considered critical for the sponge-SOB consortium. Our study provides insights into SOB of sponge-specific clade with thioautotrophic and versatile heterotrophic metabolism relevant to its roles in the micro-environment of the sponge body. © 2014 Society for Applied Microbiology and John Wiley & Sons Ltd.

The efficacy of combining use of N-acetylcysteine (NAC) and sodium bicarbonate (SOB) in the prevention of contrast-induced nephropathy (CIN) after cardiac catheterization and percutaneous coronary intervention (PCI) is unclear. All relevant studies that compared the effect of combining the use of NAC and SOB with individual use on CIN in patients undergoing cardiac catheterization and PCI were identified by searching the databases including Pubmed, Embase, Cochrane Library, and Web of Science without time and language limitation. Only randomized controlled trials (RCTs) with full-text published were considered. Sixteen RCTs involving 4432 cases were included into this meta-analysis. The results showed there were no additional benefit in reduction of CIN in COM group (COM versus NAC: RR 0.85, 95% CI 0.70-1.03, P=0.103; COM versus SOB: RR 0.91, 95% CI 0.71-1.16, P=0.449), even in patients with diabetes mellitus (COM versus NAC: RR 1.11, 95% CI 0.71-1.75, P=0.646; COM versus SOB: RR 1.06, 95% CI 0.45-2.47, P=0.893), undergoing PCI procedure (COM versus NAC: RR0.76, 95% CI 0.39-1.47, P=0.411; COM versus SOB: RR0.96, 95% CI 0.65-1.40, P=0.814), or with baseline renal dysfunction (COM versus NAC: RR 0.89, 95% CI 0.70-1.14, P=0.366; COM versus SOB: RR 0.95, 95% CI 0.67-1.36, P=0.788). The present study demonstrated combining use of NAC and SOB was not significantly superior to individual use method in the prevention of CIN after cardiac catheterization and PCI.

To assess the correlation between culture results of section's osseous slice biopsy (SOB) and the distal infected site responsible for the amputation performed concomitantly during major amputation of lower extremity. The influence of a positive culture of SOB on the patients' outcome was also evaluated. We conducted a retrospective study of medical charts of patients who underwent SOB during major amputation of lower extremity at our institution from 2000 to 2009. Fifty-seven patients (42 males/15 females, mean age 52.16years) who undergone major limb amputation (47 below knee and ten above knee) were included. The initial medical conditions of the investigated patients were: trauma (n=32), infection (n=13), trophic disorders (n=10) and tumor (n=2). The major cause of amputation was an uncontrolled infection, accouting for 64.9% of the cases (37/57) (foot=5, ankle=8, leg=24), the remaining 20 patients had trophic disorders of lower limb. Twenty-one (36.8%) from 57 biopsies were sterile, 12 (21.1%) doubtful and 24 (42.1%) positive. Thirty-one (54.4%) patients had an antibiotic-free interval before limb amputation. Independently of the bacterial species, 69.6% of the microorganisms identified from SOB were found in the distal infected site. Patients with positive SOB had a significantly longer interval between the decision to amputate the patient and the surgical procedure (200.2 vs. 70.1days; P<0.03) and a shorter total duration of antibiotic therapy before amputation than patients with negative SOB (3.68 vs. 6.08months; P<0.03). The delay for complete healing was significantly higher in patients with a positive SOB compared with those with a negative SOB (3.57 vs. 2.48months; P<0.03). Our results suggest that the infection may extend from the distal site to the level of amputation in a large proportion of cases and that the delay with which the amputation is performed after the decision has been taken may play a role in this event.

The Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) score is commonly used, although the utility regarding this score in staging dementia severity is not well established. To investigate the effectiveness of CDR-SOB scores in staging dementia severity compared with the global CDR score. Retrospective study. Texas Alzheimer's Research Consortium minimum data set cohort. A total of 1577 participants (110 controls, 202 patients with mild cognitive impairment, and 1265 patients with probable Alzheimer disease) were available for analysis. Receiver operating characteristic curves were generated from a derivation sample to determine optimal cutoff scores and ranges, which were then applied to the validation sample. Optimal ranges of CDR-SOB scores corresponding to the global CDR scores were 0.5 to 4.0 for a global score of 0.5, 4.5 to 9.0 for a global score of 1.0, 9.5 to 15.5 for a global score of 2.0, and 16.0 to 18.0 for a global score of 3.0. When applied to the validation sample, kappa scores ranged from 0.86 to 0.94 (P < .001 for all), with 93.0% of the participants falling within the new staging categories. The CDR-SOB score compares well with the global CDR score for dementia staging. Owing to the increased range of values, the CDR-SOB score offers several advantages over the global score, including increased utility in tracking changes within and between stages of dementia severity. Interpretive guidelines for CDR-SOB scores are provided.

Harness That S.O.B.: Distributing Remote Sensing Analysis in a Small Office/Business

Researchers in a small office/business (SOB) operate with limited funding, equipment, and software availability. To mitigate these issues, we developed a distributed computing framework that: 1) leverages open source software to implement functionality otherwise reliant on proprietary software and 2) harnesses the unused power of (semi-)idle office computers with mixed operating systems (OSes). This abstract outlines some reasons for the effort, its conceptual basis and implementation, and provides brief speedup results. The Multiple-Endmember Linear Spectral Unmixing Model (MELSUM)1 processes remote-sensing (hyper-)spectral images. The algorithm is computationally expensive, sometimes taking a full week or more for a 1 million pixel/100 wavelength image. Analysis of pixels is independent, so a large benefit can be gained from parallel processing techniques. Job concurrency is limited by the number of active processing units. MELSUM was originally written in the Interactive Data Language (IDL). Despite its multi-threading capabilities, an IDL instance executes on a single machine, and so concurrency is limited by the machine's number of central processing units (CPUs). Network distribution can access more CPUs to provide a greater speedup, while also taking advantage of (often) underutilized extant equipment. appropriately integrating open source software magnifies the impact by avoiding the purchase of additional licenses. Our method of distribution breaks into four conceptual parts: 1) the top- or task-level user interface; 2) a mid-level program that manages hosts and jobs, called the distribution server; 3) a low-level executable for individual pixel calculations; and 4) a control program to synchronize sequential sub-tasks. Each part is a separate OS process, passing information via shell commands and/or temporary files. While the control and low-level executables are short-lived, the top-level program and distribution server run (at least) for the entirety of

Objective To determine whether spinal anesthesia combined with obturator nerve blockade (SOB) is effective in preventing obturator nerve stimulation, jerking and bladder perforation during transurethral resection of bladder tumor (TURBT). Material and methods In this clinical trial, 30 patients were randomly divided into two groups: spinal anesthesia (SA) and SOB. In SA group, 2.5 cc of 0.5% bupivacaine was injected intrathecally using a 25-gauge spinal needle and in SOB after spinal anesthesia, a classic obturator nerve blockade was performed by using nerve stimulation technique. Results There was a statistically significant difference between jerking in both groups (p=0.006). During the TURBT, surgeon satisfaction was significantly higher in SOB group compared to SA group (p=0.006). There was no significant correlation between sex, patient age and location of bladder tumor between the groups (p>0.05). Conclusion Obturator nerve blockade by using 15 cc lidocaine 1% is effective in preventing adductor muscle spasms during TURBT. PMID:29201516

Succession of Sulfur-Oxidizing Bacteria in the Microbial Community on Corroding Concrete in Sewer Systems† ▿

Microbially induced concrete corrosion (MICC) in sewer systems has been a serious problem for a long time. A better understanding of the succession of microbial community members responsible for the production of sulfuric acid is essential for the efficient control of MICC. In this study, the succession of sulfur-oxidizing bacteria (SOB) in the bacterial community on corroding concrete in a sewer system in situ was investigated over 1 year by culture-independent 16S rRNA gene-based molecular techniques. Results revealed that at least six phylotypes of SOB species were involved in the MICC process, and the predominant SOB species shifted in the following order: Thiothrix sp., Thiobacillus plumbophilus, Thiomonas intermedia, Halothiobacillus neapolitanus, Acidiphilium acidophilum, and Acidithiobacillus thiooxidans. A. thiooxidans, a hyperacidophilic SOB, was the most dominant (accounting for 70% of EUB338-mixed probe-hybridized cells) in the heavily corroded concrete after 1 year. This succession of SOB species could be dependent on the pH of the concrete surface as well as on trophic properties (e.g., autotrophic or mixotrophic) and on the ability of the SOB to utilize different sulfur compounds (e.g., H2S, S0, and S2O32−). In addition, diverse heterotrophic bacterial species (e.g., halo-tolerant, neutrophilic, and acidophilic bacteria) were associated with these SOB. The microbial succession of these microorganisms was involved in the colonization of the concrete and the production of sulfuric acid. Furthermore, the vertical distribution of microbial community members revealed that A. thiooxidans was the most dominant throughout the heavily corroded concrete (gypsum) layer and that A. thiooxidans was most abundant at the highest surface (1.5-mm) layer and decreased logarithmically with depth because of oxygen and H2S transport limitations. This suggested that the production of sulfuric acid by A. thiooxidans occurred mainly on the concrete surface and the

As médias dos valores pré- e pós-broncodilatador foram claramente inferiores aos valores de referência para todos os parâmetros, especialmente FEF25-75%. Houve uma melhora pós-broncodilatador. Quando medidos como aumentos percentuais médios, VEF1 e FEF25-75% melhoraram em 11% e 20%, respectivamente. Entretanto, quando os valores absolutos foram calculados, as médias de VEF1 e FEF25-75% aumentaram somente em 0,1 l. Verificamos que a idade da agressão viral, história familiar de asma e alergia não tiveram efeitos significativos na resposta ao broncodilatador. Pacientes pediátricos com BOPI têm uma obstrução das vias aéreas periféricas que responde ao tratamento, mas não uma reversão completa com o broncodilatador. O conceito de BOPI como obstrução fixa e irreversível parece não se aplicar a essa população. Nossos dados sugerem que a obstrução de vias aéreas em pacientes com BOPI é variável, e esse achado pode ter importantes implicações clínicas.

The microbial biocenosis in highly saline fluids produced from the cold well of a deep geothermal heat store located in the North German Basin was characterized during regular plant operation and immediately after plant downtime phases. Genetic fingerprinting revealed the dominance of sulfate-reducing bacteria (SRB) and fermentative Halanaerobiaceae during regular plant operation, whereas after shutdown phases, sequences of sulfur-oxidizing bacteria (SOB) were also detected. The detection of SOB indicated oxygen ingress into the well during the downtime phase. High 16S ribosomal RNA (rRNA) and dsrA gene copy numbers at the beginning of the restart process showed an enrichment of bacteria, SRB, and SOB during stagnant conditions consistent with higher concentrations of dissolved organic carbon (DOC), sulfate, and hydrogen sulfide in the produced fluids. The interaction of SRB and SOB during plant downtimes might have enhanced the corrosion processes occurring in the well. It was shown that scale content of fluids was significantly increased after stagnant phases. Moreover, the sulfur isotopic signature of the mineral scales indicated microbial influence on scale formation.

Personality traits are complex phenotypes influenced by interactions of multiple genetic variants of small effect and environmental factors. It has been suggested that the brain derived neurotrophic factor gene (BDNF) is involved in personality traits. Season of birth (SOB) has also been shown to affect personality traits due to its influences on brain development during prenatal and early postnatal periods. The present study aimed to investigate the effects of BDNF on personality traits; and the modifying effects of SOB and sex on associations between BDNF and personality traits. A sample of 1018 young adults (68% women; age range 17-25years) of Caucasian origin from the Russian Federation was assessed on personality traits (Novelty Seeking, Harm Avoidance, Reward Dependence, Persistence, Self-directedness, Cooperativeness, Self-transcendence) with the Temperament and Character Inventory-125 (TCI-125). Associations between personality traits and 12 BDNF SNPs were tested using linear regression models. The present study demonstrated the effect of rs11030102 on Persistence in females only (PFDR=0.043; r(2)=1.3%). There were significant interaction effects between Val66Met (rs6265) and SOB (PFDR=0.048, r(2)=1.4%), and between rs2030323 and SOB (PFDR=0.042, r(2)=1.3%), on Harm Avoidance. Our findings provide evidence for the modifying effect of SOB on the association between BDNF and Harm Avoidance, and for the modifying effect of sex on the association between BDNF and Persistence.

Hypothalamic-Pituitary-Thyroid Axis Perturbations in Male Mice by CNS-Penetrating Thyromimetics.

Ferrara, Skylar J; Bourdette, Dennis; Scanlan, Thomas S

2018-07-01

Thyromimetics represent a class of experimental drugs that can stimulate tissue-selective thyroid hormone action. As such, thyromimetics should have effects on the hypothalamic-pituitary-thyroid (HPT) axis, but details of this action and the subsequent effects on systemic thyroid hormone levels have not been reported to date. Here, we compare the HPT-axis effects of sobetirome, a well-studied thyromimetic, with Sob-AM2, a newly developed prodrug of sobetirome that targets sobetirome distribution to the central nervous system (CNS). Similar to endogenous thyroid hormone, administration of sobetirome and Sob-AM2 suppress HPT-axis gene transcript levels in a manner that correlates to their specific tissue distribution properties (periphery vs CNS, respectively). Dosing male C57BL/6 mice with sobetirome and Sob-AM2 at concentrations ≥10 μg/kg/d for 29 days induces a state similar to central hypothyroidism characterized by depleted circulating T4 and T3 and normal TSH levels. However, despite the systemic T4 and T3 depletion, the sobetirome- and Sob-AM2-treated mice do not show signs of hypothyroidism, which may result from the presence of the thyromimetic in the thyroid hormone-depleted background.

Vemurafenib ha probado ser una herramienta útil en el tratamiento de melanoma metastásico con mutación BRAF-V600E. Los efectos adversos incluyen artralgias, fatiga y toxicidad cutánea, siendo infrecuente la paniculitis. Presentamos el caso de una paciente de 43 años con melanoma metastásico que desarrolla lesiones subcutáneas dolorosas en miembros inferiores y superiores, asociadas a clínica sistémica después de 2 semanas de inicio de tratamiento con Vemurafenib + Cobimetinib. La histología demostró paniculitis linfocitaria septal y lobulillar. La paciente tuvo mala tolerancia al tratamiento anti diana a dosis plenas, requiriendo su ajuste, generando una corticodependencia para controlar sintomatología, y que finalmente obligó a la descontinuación de la terapia dirigida contra melanoma.  A la fecha, se han descrito 29 casos en la literatura de paniculitis asociada a vemurafenib, siendo la mayoría paniculitis neutrofílicas con adecuado control de sintomatología asociando antiinflamatorios no esteroidales y/o corticoides orales sin requerir en su mayoría modificación de la terapia contra melanoma; sin embargo hay que tener presente que pueden haber casos con mala evolución que obligan a la reducción de dosis de vemurafenib y descontinuar el tratamiento, como ha ocurrido en nuestro reporte.Vemurafenib has proven to be a useful tool in the treatment of metastatic melanoma with BRAF-V600E mutation.

Background The Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) score is commonly used, although the utility regarding this score in staging dementia severity is not well established. Obiective To investigate the effectiveness of CDRSOB scores in staging dementia severity compared with the global CDR score. Design Retrospective study. Setting Texas Alzheimer's Research Consortium minimum data set cohort. Participants A total of 1577 participants (110 controls, 202 patients with mild cognitive impairment, and 1265 patients with probable Alzheimer disease) were available for analysis. Main Outcome Measures Receiver operating characteristic curves were generated from a derivation sample to determine optimal cutoff scores and ranges, which were then applied to the validation sample. Results Optimal ranges of CDR-SOB scores corresponding to the global CDR scores were 0.5 to 4.0 for a global score of 0.5, 4.5 to 9.0 for a global score of 1.O, 9.5 to 15.5 for a global score of 2.0, and 16.0 to 18.0 for a global score of 3.0. When applied to the validation sample, κ scores ranged from 0.86 to 0.94 (P <.001 for all), with 93.0% of the participants falling within the new staging categories. Conclusions The CDR-SOB score compares well with the global CDR score for dementia staging. Owing to the increased range of values, the CDR-SOB score offers several advantages over the global score, including increased utility in tracking changes within and between stages of dementia severity. Interpretive guidelines for CDR-SOB scores are provided. PMID:18695059

Biogenic sulfuric acid (BSA) corrosion damages sewerage and wastewater treatment facilities but is not well investigated in sludge digesters. Sulfur/sulfide oxidizing bacteria (SOB) oxidize sulfur compounds to sulfuric acid, inducing BSA corrosion. To obtain more information on BSA corrosion in sludge digesters, microbial communities from six different, BSA-damaged, digesters were analyzed using culture dependent methods and subsequent polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE). BSA production was determined in laboratory scale systems with mixed and pure cultures, and in-situ with concrete specimens from the digester headspace and sludge zones. The SOB Acidithiobacillus thiooxidans, Thiomonas intermedia, and Thiomonas perometabolis were cultivated and compared to PCR-DGGE results, revealing the presence of additional acidophilic and neutrophilic SOB. Sulfate concentrations of 10-87 mmol/L after 6-21 days of incubation (final pH 1.0-2.0) in mixed cultures, and up to 433 mmol/L after 42 days (final pH <1.0) in pure A. thiooxidans cultures showed huge sulfuric acid production potentials. Additionally, elevated sulfate concentrations in the corroded concrete of the digester headspace in contrast to the concrete of the sludge zone indicated biological sulfur/sulfide oxidation. The presence of SOB and confirmation of their sulfuric acid production under laboratory conditions reveal that these organisms might contribute to BSA corrosion within sludge digesters. Elevated sulfate concentrations on the corroded concrete wall in the digester headspace (compared to the sludge zone) further indicate biological sulfur/sulfide oxidation in-situ. For the first time, SOB presence and activity is directly relatable to BSA corrosion in sludge digesters.

The aim of this study was to evaluate the efficacy of low-level laser therapy (LLLT) and alpha-lipoic acid (ALA) in the treatment of burning mouth syndrome (BMS) and secondary oral burning (SOB) by unstimulated sialometry, symptom assessment, and measurement of salivary TNF-α levels. Forty-four patients were randomized into four treatment groups: BMS/laser (n = 10), BMS/ALA (n = 5), SOB/laser (n = 15), and SOB/ALA (n = 14). The control group consisted of eight healthy female subjects. Unstimulated salivary flow was measured before and after treatment, and the collected saliva was stored at - 20 °C for the analysis of TNF-α. Symptoms were evaluated before and after treatment using a pain visual analog scale. Most patients were women (81.8%) during menopause (72.2%). LLLT and ALA were efficient in increasing salivary flow only in BMS but provided symptom relief in both conditions. TNF-α levels did not differ between patients with BMS and SOB or between those patients and the control group. No differences were observed in posttreatment TNF-α levels in either condition. The results of this study suggest that LLLT and ALA are efficient therapies in reducing burning mouth symptoms, with LLLT being more efficient than ALA.

Thal Amyloid Stages Do Not Significantly Impact the Correlation Between Neuropathological Change and Cognition in the Alzheimer Disease Continuum.

The 2012 neuropathological criteria for the diagnosis of Alzheimer disease (AD) summarize the extent of AD neuropathological change with an ABC score, which is a composite of the Thal stage of amyloid deposition (A), the Braak stage of neurofibrillary tangles (NFTs) (B), and the CERAD neuritic plaque score (C). NFTs and neuritic plaques are well-established contributors to cognitive impairment, but whether the Thal amyloid stage independently predicts antemortem cognition remains unknown. We used the National Alzheimer's Coordinating Center autopsy data set to build adjacent-categories logit regression models with CDR-SOB and Mini-Mental State Examination (MMSE) scores as cognitive outcome variables. Increasing CERAD scores were independently associated with higher CDR-SOB scores, whereas increasing Braak NFT stages predicted both higher CDR-SOB and lower MMSE scores. Increasing Thal amyloid stages were not significantly independently associated with either outcome measure. Increasing ABC scores predicted higher CDR-SOB and lower MMSE scores. These results raise the possibility that Thal amyloid stages do not substantially contribute to predicting antemortem cognition compared to CERAD neuritic plaque scores and Braak NFT stages, and suggest that the diffuse amyloid deposits participating in the assignment of Thal amyloid stages are neutral with respect to clinically detectable cognitive and functional changes. © 2016 American Association of Neuropathologists, Inc.

Once a biliary injury has occurred, repair is done by a hepaticojejunostomy. The most common procedure is to perform a dilatation with balloon with a success of 70 %. Success rates range using biodegradable stents is from 85% to 95%. Biodegradable biliary stents should change the treatment of this complication. To investigate the use of biodegradable stents in a group of patients with hepaticojejunonostomy strictures. In a prospective study 16 biodegradable stents were placed in 13 patients with hepaticojejunostomy strictures secondary to bile duct repair of a biliary surgical injury. Average age was 38.7 years (23-67), nine were female and four male. All cases had a percutaneous drainage before at the time of biodegradable stent placement. In one case, temporary haemobilia was present requiring blood transfusion. In another, pain after stent placement required intravenous medication. In the other 11 patients, hospital discharge was the next morning following stent placement. During the patient´s follow-up, none presented symptoms during the first nine months. One patient presented significant alkaline phosphatase elevation and stricture recurrence was confirmed. One case had recurrence of cholangitis 11 months after the stent placement. 84.6% continued asymptomatic with a mean follow-up of 20 months. The placement of biodegradable stents is a safe and feasible technique. Was not observed strictures caused by the stent or its degradation. It could substitute balloon dilation in strictures of hepaticojejunostomy. Uma vez que lesão biliar ocorreu, o reparo é feito por hepaticojejunostomia.

Nosso objetivo foi revisar as evidências disponíveis e obter algumas conclusões sobre o futuro papel da fase de "tratamento pós-tuberculose", que irá potencialmente impactar milhões de casos todos os anos. Realizou-se uma revisão não sistemática da literatura tendo como base uma pesquisa no PubMed usando palavras-chave específicas (várias combinações dos termos "tuberculose", "reabilitação", "tuberculose multirresistente", "doença pulmonar", "doença pulmonar obstrutiva", e "medidas de volume pulmonar"). As listas de referências dos artigos principais foram recuperadas para melhorar a sensibilidade da busca. Foram selecionados manuscritos escritos em inglês, espanhol e russo. As principais áreas de interesse foram sequelas de tuberculose após diagnóstico e tratamento; "pulmão destruído"; avaliação funcional das sequelas; intervenções de reabilitação pulmonar (fisioterapia, oxigenoterapia de longo prazo e ventilação); e tuberculose multirresistente. As evidências encontradas sugerem que a tuberculose é definitivamente responsável por sequelas funcionais, principalmente causando um padrão obstrutivo na espirometria (mas também padrões restritivos e mistos) e que há razão para a reabilitação pulmonar. Fornecemos também uma lista de variáveis a serem discutidas em futuros estudos sobre reabilitação pulmonar em pacientes com sequelas pós-tuberculose.

Literature suggests that the effect of winter birth on vulnerability to schizophrenia might be mediated by increased expression of proinflammatory cytokines due to prenatal infection and its inadequate regulation by anti-inflammatory factors. As the response of the immune system depends on genotype, this study assessed the interaction effects of cytokine genes and season of birth (SOB) on schizotypy measured with the Schizotypal Personality Questionnaire (SPQ-74). We searched for associations of IL1B rs16944, IL4 rs2243250, and IL-1RN VNTR polymorphisms, SOB, and their interactions with the SPQ-74 total score in a sample of 278 healthy individuals. A significant effect of the IL4 X SOB interaction was found, p = 0.007 and η2 = 0.028. We confirmed this effect using an extended sample of 373 individuals. Homozygotes CC born in winter showed the highest SPQ total score and differed significantly from winter-born T allele carriers, p = 0.049. This difference was demonstrated for cognitive-perceptual and disorganized but not interpersonal dimensions. The findings are consistent with the hypothesis that the cytokine genes by SOB interaction can influence variability of schizotypal traits in the general population. The IL4 T allele appeared to have a protective effect against the development of positive and disorganized schizotypal traits in winter-born individuals. PMID:29464121

Season of birth (SOB) has been investigated as one of the environmental factors that might epigenetically determine the physiology of individuals. This study investigated the role of SOB in the association between Quality of Life (QOL), a proxy of psychological stress status, and C-reactive protein (CRP) concentration (i.e., inflammatory status) among 1,085 adults (aged 20-57 years old) in Hainan Island, China. High sensitivity CRP concentration was measured in dried blood spot samples, while the abbreviated version of the World Health Organization's QOL questionnaire was used to gather information on six QOL domains. Analysis stratified by three historically distinct age groups revealed a significant association between CRP concentration, SOB, QOL and an interaction between SOB and QOL among the youngest and oldest groups. In the oldest group, those born in the dry season had a higher CRP concentration with worse QOL whereas in the youngest group, there was a higher CRP concentration with better QOL. Annual per capita rice production, a proxy of population nutritional status in the year of birth, was found to predict CRP concentration only among the second oldest group. These findings suggest that the early environment might affect the immune response to psychological stress in adulthood and that its effect may differ by the time period in which people were born.

Summary Objectives: To determine the influence of maxillary posterior discrepancy on upper molar vertical position and dentofacial vertical dimensions in individuals with or without skeletal open bite (SOB). Materials and methods: Pre-treatment lateral cephalograms of 139 young adults were examined. The sample was divided into eight groups categorized according to their sagittal and vertical skeletal facial growth pattern and maxillary posterior discrepancy (present or absent). Upper molar vertical position, overbite, lower anterior facial height and facial height ratio were measured. Independent t-test was performed to determine differences between the groups considering maxillary posterior discrepancy. Principal component analysis and MANCOVA test were also used. Results: No statistically significant differences were found comparing the molar vertical position according to maxillary posterior discrepancy for the SOB Class I group or the group with adequate overbite. Significant differences were found in SOB Class II and Class III groups. In addition, an increased molar vertical position was found in the group without posterior discrepancy. Limitations: Some variables closely related with the individual’s intrinsic craniofacial development that could influence the evaluated vertical measurements were not considered. Conclusions and implications: Overall maxillary posterior discrepancy does not appear to have a clear impact on upper molar vertical position or facial vertical dimensions. Only the SOB Class III group without posterior discrepancy had a significant increased upper molar vertical position. PMID:26385786

To describe our experience with video-assisted thoracic surgery (VATS) for anatomic pulmonary resection at a referral center for thoracic surgery in Brazil. All patients who underwent anatomic pulmonary resection by VATS between 2010 and 2015 were included. Clinical and pathological data, as well as postoperative complications, were analyzed. A total of 117 pulmonary resections by VATS were performed, of which 98 were lobectomies and 19 were anatomic segmentectomies. The mean age of the patients was 63.6 years (range, 15-86 years). Females predominated (n = 69; 59%). The mean time to chest tube removal was 2.47 days, and the mean length of ICU stay was 1.88 days. The mean length of hospital stay was 4.48 days. Bleeding ≥ 400 mL occurred in 15 patients. Conversion to thoracotomy was required in 4 patients. Our results are similar to those published in major international studies, indicating that VATS is an important strategy for pulmonary resection. They also show that VATS can be safely performed with adequate training. This technique should be used more often for the treatment of lung diseases in Brazil.

Learn the perceptions of patients with sexually transmitted infections and sexual partners who are notified of the infection. A descriptive and qualitative study, based on the collective subject discourse technique, was conducted in four healthcare centers of reference in Fortaleza, Ceará, from March to July 2014. The sample comprised 21 subjects (11 index patients and 10 notified partners). The index patients reported complicity, concern about the partner's health and revelation of diagnosis aiming to preserve the relationship. The partners showed antagonistic perceptions: tranquility-betrayal, fear of death, of incurability and the diagnosis, especially of HIV. The reasons for coming to a healthcare center were: fear of being sick, attenuation of guilt of infection transmission, need for diagnosis, early start of treatment. Fear of losing trust, insecurities when dealing with a sexual infection and being responsible or co-responsible for the transmission were the predominant feelings. Various types of partner notification were reported (verbal, telephone, notification card), according to individual convenience. This study suggests the use of alternative methods of notification and an integrated system of notification.

Resumo O complexo tratamento de dissecção da aorta ainda apresenta controvérsias devido à gravidade do caso e à necessidade de individualização da terapêutica. A gravidade relaciona-se ao difícil diagnóstico pelas queixas inespecíficas e pelas graves complicações inerentes à evolução da doença (ruptura aórtica, síndrome de má perfusão, dissecção retrógrada, dor ou hipertensão refratária). Este relato apresenta um homem de 61 anos, tabagista e hipertenso mal controlado, que evoluiu para dissecção aórtica de tipo B de Stanford. Foi abordado através de técnica endovascular com uso de endoprótese com stent para tratamento do caso após falha do tratamento medicamentoso. O tratamento endovascular mostrou-se uma ferramenta eficaz para o tratamento definitivo, com boa taxa de sobrevida ao final do primeiro ano após o procedimento.

To determine the influence of maxillary posterior discrepancy on upper molar vertical position and dentofacial vertical dimensions in individuals with or without skeletal open bite (SOB). Pre-treatment lateral cephalograms of 139 young adults were examined. The sample was divided into eight groups categorized according to their sagittal and vertical skeletal facial growth pattern and maxillary posterior discrepancy (present or absent). Upper molar vertical position, overbite, lower anterior facial height and facial height ratio were measured. Independent t-test was performed to determine differences between the groups considering maxillary posterior discrepancy. Principal component analysis and MANCOVA test were also used. No statistically significant differences were found comparing the molar vertical position according to maxillary posterior discrepancy for the SOB Class I group or the group with adequate overbite. Significant differences were found in SOB Class II and Class III groups. In addition, an increased molar vertical position was found in the group without posterior discrepancy. Some variables closely related with the individual's intrinsic craniofacial development that could influence the evaluated vertical measurements were not considered. Overall maxillary posterior discrepancy does not appear to have a clear impact on upper molar vertical position or facial vertical dimensions. Only the SOB Class III group without posterior discrepancy had a significant increased upper molar vertical position. © The Author 2015.

Bariatric surgery is performed all over the world with close to 500.000 procedures per year. The most performed techniques are Roux-en-Y gastric bypass and sleeve gastrectomy. Despite this data, the most effective procedure, biliopancreatic diversion with or without duodenal switch, represents only no more than 1.5% of the procedures. Technical complexity, morbidity, mortality, and severe nutritional adverse effects related to the procedure are the main fears that prevent most universal acceptance. To explain the technical aspects and the benefits of the SADI-S with right gastric artery ligation as an effective simplification from the original duodenal switch. Were included all patients undergoing this procedure from the November 2014 to May 2016, describing and analysing aspects of this technique, the systematization and early complications associated with the procedure. A series of 67 patients were operated; 46 were women (68.7%); mean age of the group was 44 years old (33-56); and an average BMI of 53.5 kg/m2 (50-63.5). Surgical time was 115 min (80-180). A total of five patients (7.5%) had any complication and two (2.9%) had to be reoperated. There were two patients with leak, one at the duodenal stump and other at the esophagogastric angle. There was no mortality. Patients stayed at the hospital a median of 2.5 days (1-25). SADI-S with right gastric artery ligation is a safe procedure with few preliminary complications. The technical variations introduced to the classical duodenal switch are reproducible and may allow this procedure to be more popular. All the complications in this series were not related to the ligation of the right gastric artery. Cerca de 500.000 cirurgias bariátricas são realizadas a cada ano em todo o mundo. As técnicas mais realizadas são o bypass gástrico em Y-de-Roux e a gastrectomia vertical. A derivação biliopancreática, com ou sem duodenal switch, é considerada técnica mais eficaz no tratamento cirúrgico do paciente obeso

To determine the correlations between coping strategies, depression, stress levels and pain perception in patients with endometriosis. This prospective and exploratory study included 171 women undergoing treatment for endometriosis between April and August 2014. The questionnaires used were Brief COPE, Beck Depression Inventory, Lipp's Stress Symptom Inventory for Adults and Visual Analogue Scale. Clinical data were collected from electronic medical records. Patients with endometriosis who used positive coping strategies had better adaptation to stress (p<0.004) and less depression (p<0.004). The presence and intensity of depression, stress and acyclic pelvic pain were directly associated (p<0.05). The intensity of dysmenorrhea was associated with the degree of depression (p<0.001), whereas acyclic pelvic pain was associated with the degree of depression (p<0.001), stress level (p<0.001) and stress type (p<0.001). We found a positive association between coping, depression levels, type and levels of stress and pain intensity in patients with endometriosis. The use of maladaptive coping strategies focused on emotion is correlated with increase in depression and stress.

Despite the important biological effects of jabuticaba, its actions on the cardiovascular system have not been clarified. To determine the effects of jabuticaba hydroalcoholic extract (JHE) on vascular smooth muscle (VSM) of isolated arteries. Endothelium-denuded aortic rings of rats were mounted in isolated organ bath to record isometric tension. The relaxant effect of JHE and the influence of K+ channels and Ca2+ intra- and extracellular sources on JHE-stimulated response were assessed. Arteries pre-contracted with phenylephrine showed concentration-dependent relaxation (0.380 to 1.92 mg/mL). Treatment with K+ channel blockers (tetraethyl-ammonium, glibenclamide, 4-aminopyridine) hindered relaxation due to JHE. In addition, phenylephrine-stimulated contraction was hindered by previous treatment with JHE. Inhibition of sarcoplasmic reticulum Ca2+ ATPase did not change relaxation due to JHE. In addition, JHE inhibited the contraction caused by Ca2+ influx stimulated by phenylephrine and KCl (75 mM). JHE induces endothelium-independent vasodilation. Activation of K+ channels and inhibition of Ca2+ influx through the membrane are involved in the JHE relaxant effect. Embora a jabuticaba apresente importantes efeitos biológicos, suas ações sobre o sistema cardiovascular ainda não foram esclarecidas. Determinar os efeitos do extrato de jabuticaba (EHJ) sobre o músculo liso vascular (MLV) em artérias isoladas. Aortas (sem endotélio) de ratos foram montadas em banho de órgãos isolados para registro de tensão isométrica. Foram verificados o efeito relaxante, a influência dos canais de K+ e das fontes de Ca2+ intra- e extracelular sob a resposta estimulada pelo EHJ. Artérias pré-contraídas com fenilefrina apresentaram relaxamento concentração-dependente (0,380 a 1,92 mg/mL). O tratamento com bloqueadores de canais de K+ (tetraetilamônio, glibenclamida, 4-aminopiridina) prejudicaram o relaxamento pelo EHJ. A contração estimulada com fenilefrina tamb

Reduction and stabilization of solid wastes generated during space missions is a major concern for the Advanced Life Support - Resource Recovery program at the NASA, Kennedy Space Center. Solid wastes provide substrates for pathogen proliferation, produce strong odor, and increase storage requirements during space missions. A five periods experiment was conducted to evaluate the Space Operation Bioconverter (SOB), an in vessel composting system, as a biological processing technology to reduce and stabilize simulated long-term missions space related solid-wastes (SRSW). For all periods, SRSW were sorted into components with fast (FBD) and slow (SBD) biodegradability. Uneaten food and plastic were used as a major FBD and SBD components, respectively. Compost temperature (C), CO2 production (%), mass reduction (%), and final pH were utilized as criteria to determine compost quality. In period 1, SOB was loaded with a 55% FBD: 45% SBD mixture and was allowed to compost for 7 days. An eleven day second composting period was conducted loading the SOB with 45% pre-composted SRSW and 55% FBD. Period 3 and 4 evaluated the use of styrofoam as a bulking agent and the substitution of regular by degradable plastic on the composting characteristics of SRSW, respectively. The use of ceramic as a bulking agent and the relationship between initial FBD mass and heat production was investigated in period 5. Composting SRSW resulted in an acidic fermentation with a minor increase in compost temperature, low CO2 production, and slightly mass reduction. Addition of styrofoam as a bulking agent and substitution of regular by biodegradable plastic improved the composting characteristics of SRSW, as evidenced by higher pH, CO2 production, compost temperature and mass reduction. Ceramic as a bulking agent and increase the initial FBD mass (4.4 kg) did not improve the composting process. In summary, the SOB is a potential biological technology for reduction and stabilization of mission space

This is a final report for Department of Energy Grant No. DE-FG02-08ER15927 entitled “Molecular Genetic Analysis of Activation-Tagged Transcription Factors Thought to be Involved in Photomorphogenesis”. Based on our preliminary photobiological and genetic analysis of the sob1-D mutant, we hypothesized that OBP3 is a transcription factor involved in both phytochrome and cryptochrome-mediated signal transduction. In addition, we hypothesized that OBP3 is involved in auxin signaling and root development. Based on our preliminary photobiological and genetic analysis of the sob2-D mutant, we also hypothesized that a related gene, LEP, is involved in hormone signaling and seedling development.

áveis, portadores de DPOC e hipoxemia leve (saturação de oxigênio = 90-94%) em um centro clínico especializado no atendimento de doenças respiratórias em Goiânia (GO). Os pacientes foram submetidos à avaliação clínica, espirometria, polissonografia, ecocardiografia, gasometria arterial, teste de caminhada de seis minutos e radiografia de tórax. Foram avaliados 64 pacientes com DPOC e hipoxemia leve, e 39 (61%) apresentaram distúrbios respiratórios do sono (14 com AOS e 25 com hipoxemia noturna isolada). A análise de correlação mostrou moderada correlação da PaO2 com saturação média do sono (r = 0,45; p = 0,0002), saturação média do sono rapid eye movement (REM; r = 0,43; p = 0,001) e saturação média do sono não-REM (r = 0,42; p = 0,001). Um ponto de corte de PaO2 ≤ 70 mmHg (OR = 4,59; IC95%: 1,54-13,67; p = 0,01) na gasometria arterial foi significativamente associada com distúrbios respiratórios do sono. O modelo mostrou que, para identificar distúrbios respiratórios do sono, o ponto de corte teve uma especificidade de 73,9% (IC95%: 51,6-89,8%), uma sensibilidade de 63,4% (IC95%: 46,9-77,9%) e valores preditivos positivo e negativo de 81,3% (IC95%: 67,7-90,0%) e 53,1% (IC95%: 41,4-64,4%), respectivamente.

Na ultima decada emergiu uma linha de investigacao muito activa em termometros nao invasivos e precisos que possam determinar temperatura a escala nanometrica. Esta investigacao foi fortemente estimulada pelas numerosas solicitacoes da nanotecnologia e da biomedicina, por exemplo. Uma das abordagens mais promissoras propoe o uso de ioes trivalentes de lantanideos que apresenta propriedades fotoluminescentes que dependem da temperatura. Neste trabalho demonstra-se que esta tecnica combina as vantagens de te um limite de deteccao de 0.5 graus com sensibilidade ate 4.5 % K-1. Este termometro molecular pode ser processado em filmes finos ou nanoparticulas, abrindo os campos de aplicacao a diferentes utilizacoes. As nanoparticulas de silica produzidas sao caracterizadas na presenca e na ausencia de ioes lantanideos. Sem o metal, as nanoparticulas de APTES/TEOS demonstram ser luminescentes sob excitacao UV sem necessidade de utilizar qualquer tratamento termico. O rendimento quantico de emissao depende apenas da proporcao dos silanos e pode atingir o valor de 0.15 +/- 0.02. A co-dopagem destas nanoparticulas com Eu3+ e Tb3+ permite obter sondas com resposta raciometrica, com a possibilidade de ajustar a gama de temperaturas de operacao e a sensibilidade, via desenho inteligente da matriz de suporte e dos ligandos de beta-dicetona que estao coordenados ao iao metalico. Quando processados como filmes, este termometro permite o mapeamento de temperaturas com resolucao espacial 1.8 mum. A racionalizacao da dependencia de temperatura e uma ferramenta util para desenvolver termometros que operam em gamas de temperatura especificos (e.g. gama de temperatura fisiologica, 290-340 K) com sensibilidade acima de 0.5 % K-1. A combinacao de esforcos de um grande numero de diversas disciplinas ira previsivelmente permitir o surgimento de termometros moleculares novos e sofisticados, preenchendo os principais requisitos das nanociencias.

Foram obtidos dados demográficos, medicações utilizadas e tratamento coronariano adotado. O desfecho primário foi mortalidade por todas as causas. O desfecho secundário foi eventos combinados (choque cardiogênico, reinfarto, morte, acidente vascular cerebral e sangramentos). A comparação entre os grupos foi realizada por meio de Q-quadrado e teste-T. A análise multivariada foi realizada por regressão logística, sendo considerado significativo p < 0,05. Em relação ao tratamento, observou-se realização de intervenção coronária percutânea em 40,2% no grupo fondaparinux e 35,1% no grupo enoxaparina (p = 0,13). Na análise multivariada, observaram-se diferenças significativas entre os grupos fondaparinux e enoxaparina em relação a eventos combinados (13,8% vs. 22%, OR = 2,93, p = 0,007) e sangramentos (2,3% vs. 5,2%, OR = 4,55, p = 0,037), respectivamente. Semelhante aos dados recentemente publicados na literatura mundial, fondaparinux mostrou-se superior à enoxaparina para a população brasileira, com redução significativa de eventos combinados e sangramentos.

In this study, the membrane biofilm reactor (MBfR) is proposed to achieve simultaneous removal of ammonium, dissolved methane, and sulfide from main-stream and side-stream anaerobic digestion liquors. To avoid dissolved methane stripping, oxygen is introduced through gas-permeable membranes, which also from the substratum for the growth of a biofilm likely comprising ammonium oxidizing bacteria (AOB), anaerobic ammonium oxidation (Anammox) bacteria, denitrifying anaerobic methane oxidation (DAMO) microorganisms, aerobic methane oxidizing bacteria (MOB), and sulfur oxidizing bacteria (SOB). A mathematical model is developed and applied to assess the feasibility of such a system and the associated microbial community structure under different operational conditions. The simulation studies demonstrate the feasibility of achieving high-level (>97.0%), simultaneous removal of ammonium, dissolved methane, and sulfide in the MBfRs from both main-stream and side-stream anaerobic digestion liquors through adjusting the influent surface loading (or hydraulic retention time (HRT)) and the oxygen surface loading. The optimal HRT was found to be inversely proportional to the corresponding oxygen surface loading. Under the optimal operational conditions, AOB, DAMO bacteria, MOB, and SOB dominate the biofilm of the main-stream MBfR, while AOB, Anammox bacteria, DAMO bacteria, and SOB coexist in the side-stream MBfR to remove ammonium, dissolved methane, and sulfide simultaneously.

We investigated the response of microbial community to changes in H2S loading rate in a microaerated desulphurisation system treating biogas from vinasse methanisation. H2S removal efficiency was high, and both COD and DO seemed to be important parameters to biomass activity. DGGE analysis retrieved sequences of sulphide-oxidising bacteria (SOB), such as Thioalkalimicrobium sp. Deep sequencing analysis revealed that the microbial community was complex and remained constant throughout the experiment. Most sequences belonged to Firmicutes and Proteobacteria, and, to a lesser extent, Bacteroidetes, Chloroflexi, and Synergistetes. Despite the high sulphide removal efficiency, the abundance of the taxa of SOB was low, and was negatively affected by the high sulphide loading rate. Copyright © 2016 Elsevier Ltd.

Método: Desde Junio de 2005 a Diciembre de 2016, 12 pacientes con diagnóstico de MFM fueron intervenidos quirúrgicamente. Se evaluó: edad, sexo, localización de la lesión (anterior o lateral), sintomatología, tipo de abordaje utilizado y resultados postoperatorios. Resultados: De los pacientes intervenidos, 8 fueron mujeres y 4 varones. La edad promedio fue de 47 años. La localización fue anterior en 8 casos y lateral en 4 casos. La sintomatología más frecuente fue dolor occipito-cervical (8 casos), seguido de tetraparesia (3 casos). En los pacientes con MFM de localización anterior se realizó un abordaje extremo-lateral transcondilar (ELTC), mientras que en los tumores laterales el abordaje fue extremo-lateral retrocondilar (ELRC). En 10 casos la resección fue completa. En dos pacientes fue necesario dejar una pequeña lámina de meningioma sobre la arteria vertebral y a nivel del foramen yugular. Como complicaciones postoperatorias, 3 pacientes presentaron una paresia del XII nervio craneano y 2 pacientes paresia del XI nervio craneano; además, 1 paciente presentó una fístula de LCR. Conclusión: La cirugía de los MFM de localización anterior y lateral puede ser realizada de forma segura y efectiva. Es necesario: a) buen conocimiento anatómico de la región; b) disecar los músculos de la nuca en 2 planos, exponiendo el triángulo suboccipital y la arteria vertebral (AV); 3) realizar un abordaje ELRC en los tumores laterales, y ELTC en los tumores anteriores; y 4) buena técnica microquirúrgica.

To analyze the meanings produced in the Health Surveillance actions for tuberculosis control, carried out by healthcare professionals in Mozambique. Qualitative study using the theoretical and methodological framework of the French Discourse Analysis. A total of 15 healthcare professionals with more than one year of experience in disease control actions participated in the study. Four discursive blocks have emerged from the analysis: tuberculosis diagnosis process; meeting, communication and discussion of treatment; local strategies for tuberculosis control; involvement of family and community leaders in the tuberculosis control. The statements of the healthcare professionals suggest, as Health Surveillance actions, practices that include collecting sputum in the patient's home and sending it to the laboratory; deployment of the medical team with a microscope for tuberculosis testing; and testing for diseases that may be associated with tuberculosis. In this context, the actions of Health Surveillance for tuberculosis control involve valuing all actors: family, community leaders, patients and health professionals.

Cox-Maze III procedure is one of the surgical techniques used in the surgical treatment of atrial fibrillation (AF). To determine late results of Cox-Maze III in terms of maintenance of sinus rhythm, and mortality and stroke rates. Between January 2006 and January 2013, 93 patients were submitted to the cut-and-sew Cox-Maze III procedure in combination with structural heart disease repair. Heart rhythm was determined by 24-hour Holter monitoring. Procedural success rates were determined by longitudinal methods and recurrence predictors by multivariate Cox regression models. Thirteen patients that obtained hospital discharge alive were excluded due to lost follow-up. The remaining 80 patients were aged 49.9 ± 12 years and 47 (58.7%) of them were female. Involvement of mitral valve and rheumatic heart disease were found in 67 (83.7%) and 63 (78.7%) patients, respectively. Seventy patients (87.5%) had persistent or long-standing persistent AF. Mean follow-up with Holter monitoring was 27.5 months. There were no hospital deaths. Sinus rhythm maintenance rates were 88%, 85.1% and 80.6% at 6 months, 24 months and 36 months, respectively. Predictors of late recurrence of AF were female gender (HR 3.52; 95% CI 1.21-10.25; p = 0.02), coronary artery disease (HR 4.73 95% CI 1.37-16.36; p = 0.01) and greater left atrium diameter (HR 1.05; 95% CI 1.01-1.09; p = 0.02). Actuarial survival was 98.5% at 12, 24 and 48 months and actuarial freedom from stroke was 100%, 100% and 97.5% in the same time frames. The Cox-Maze III procedure, in our experience, is efficacious for sinus rhythm maintenance, with very low late mortality and stroke rates.

531 imagens contidas no The International Halley Watch Atlas of Large-Scale Phenomena (Brandt et al., 1992) cobrindo o período de setembro de 1985 a julho de 1986 foram analisadas visando identificar, caracterizar as propriedades e correlacionar estruturas morfológicas da cauda de plasma do cometa P/Halley. A análise revelou 47 eventos de desconexão (DEs) (Niedner & Brandt, 1979; Jockers, 1985; Celnik et al., 1988; Delva et al., 1991). A análise completa de todas as imagens encontra-se publicada em Voelzke & Matsuura, 1998. A distribuição dos DEs na distância heliocêntrica apresenta um caráter bimodal possivelmente associado com a distribuição espacial das fronteiras de setor magnético do meio interplanetário. Os 47 DEs fotografados em 47 imagens distintas permitiram determinar 19 origens de DEs, ou seja, o instante em que supostamente o cometa cruzou a fronteira entre setores magnéticos do vento solar. Tais dados cometários foram comparados com dados do vento solar provenientes de medidas realizadas in situ pelas sondas IMP-8, ICE e PVO, que mediram a variação da velocidade do vento solar, da densidade e da pressão dinâmica durante o intervalo analisado. Os dados destas sondas espaciais em conjunto com os da sonda Vega 1 foram usados para determinar o tempo das passagens do lençol de corrente. Com base nos dados das sondas foram calculadas as coordenadas heliográficas retroativas do lençol de corrente na "superfície fonte" dos mapas sinóticos do campo magnético de Hoeksema, 1989. O cálculo retroativo é feito através de um modelo simples de expressão do vento solar com velocidade uniforme, sendo considerada a co-rotação da magnetosfera com o Sol. Este trabalho apresenta os resultados desta comparação e a análise cinemática da origem dos DEs, determinada sob a hipótese que o plasma desconectado de um dado DE afasta-se com velocidade constante do núcleo cometário (Voelzke & Matsuura, 1998) e compara esta análise com outras que

2006-12-01

Construction workers employed in a unique type of tunnel construction known as tunnel jacking were exposed over an 18-month period to respirable crystalline silica at concentrations that exceeded the OSHA permissible exposure limit. The present study examines workplace exposures and occurrence of airway disease in these workers. Medical and occupational histories and chest radiographs were obtained on 343 active construction workers who had worked on the site during the period in question. Chest radiographs were interpreted according to the ILO-1980 system of classification. Standardized questions were used to develop an algorithm to define symptoms consistent with asthma (SCA) and to determine these respiratory outcomes: chronic bronchitis, shortness of breath (SOB), and physician-diagnosed asthma (current vs. not current). Relationships with each of three work activities were examined: slurry wall breakthrough (SWB), chipping caisson overpour, and tunneling/mining. Participants included laborers, carpenters, tunnel workers, ironworkers, operating engineers, and electricians. No cases of silicosis were found on chest X-ray. Overall prevalence of chronic bronchitis, SCA, SOB, and physician-diagnosed asthma was 10.7%, 25%, 29%, and 6.6%, respectively. Odds ratios (OR) for carpenters compared to laborers were significantly elevated for chronic bronchitis, SCA, and SOB. SWB was associated with chronic bronchitis and SCA (OR 4.93, 95% CI = 1.01, 24.17; OR 3.32, 95% CI = 1.25, 8.84, respectively). The interaction between SWB, SCA, and trade was significant for carpenters (OR 6.87, 95% CI = 1.66, 28.39). Inverse trends were observed for months on the site and chronic bronchitis, SCA, and SOB (P = 0.0374, 0.0006, and 0.0307, respectively). Tunnel construction workers exposed to respirable crystalline silica and cement dust are at increased risk for airway disease. Extent of risk varies by trade and work activity. Our data indicate the importance of bystander exposures and

Introduction We hypothesized that the indication for stress testing provided by the referring physician would be an independent predictor of all-cause mortality. Material and methods We studied 48,914 patients from The Henry Ford Exercise Testing Project (The FIT Project) without known congestive heart failure who were referred for a clinical treadmill stress test and followed for 11 ±4.7 years. The reason for stress test referral was abstracted from the clinical test order, and should be considered the primary concerning symptom or indication as stated by the ordering clinician. Hierarchical multivariable Cox proportional hazards regression was performed, after controlling for potential confounders including demographics, risk factors, and medication use as well as additional adjustment for exercise capacity in the final model. Results A total of 67% of the patients were referred for chest pain, 12% for shortness of breath (SOB), 4% for palpitations, 3% for pre-operative evaluation, 6% for abnormal prior testing, and 7% for risk factors only. There were 6,211 total deaths during follow-up. Compared to chest pain, those referred for palpitations (HR = 0.72, 95% CI: 0.60–0.86) and risk factors only (HR = 0.72, 95% CI: 0.63–0.82) had a lower risk of all-cause mortality, whereas those referred for SOB (HR = 1.15, 95% CI: 1.07–1.23) and pre-operative evaluation (HR = 2.11, 95% CI: 1.94–2.30) had an increased risk. In subgroup analysis, referral for palpitations was protective only in those without coronary artery disease (CAD) (HR = 0.75, 95% CI: 0.62–0.90), while SOB increased mortality risk only in those with established CAD (HR = 1.25, 95% CI: 1.10–1.44). Conclusions The indication for stress testing is an independent predictor of mortality, showing an interaction with CAD status. Importantly, SOB may be associated with higher mortality risk than chest pain, particularly in patients with CAD. PMID:27186173

To analyze whether an increase in patient severity and nursing workload are correlated to a greater incidence of adverse events (AEs) in critical patients. A prospective single cohort study was performed on a sample of 138 patients hospitalized in an intensive care unit (ICU). A total of 166 AEs, occurred, affecting 50.7% of the patients. Increased patient severity presented a direct relationship to the probability of AEs occurring. However, nursing workload did not present a statistically significant relationship with the occurrence of AEs. The results cast light on the importance of using evaluation tools by the nursing personnel in order to optimize their daily activities and focus on patient safety. Analisar se o aumento da gravidade do paciente e a carga de trabalho de enfermagem está relacionado à maior incidência de Eventos Adversos (EAs) em pacientes críticos. Estudo de coorte única, prospectivo, com amostra de 138 pacientes internados em uma Unidade de Terapia Intensiva (UTI). Ao todo, foram evidenciados 166 EAs, que acometeram 50,7% dos pacientes. O aumento da gravidade do paciente apresentou relação direta com a chance de ocorrência de EAs. Entretanto, a carga de trabalho de enfermagem não apresentou relação estatisticamente significativa, na ocorrência de EAs. Os resultados permitem refletir acerca da importância da equipe de enfermagem, em utilizar instrumentos de avaliação, com o objetivo de melhorar e planejar suas ações diárias, com foco na segurança do paciente.

Normal coronary flow velocity reserve (CFVR) (≥ 2) obtained in the left anterior descending coronary artery (LAD) from transthoracic echocardiography is associated with a good prognosis, but there is no study correlating CFVR with submaximal target heart rate (HR). To evaluate the prognostic value of CFVR obtained in the LAD of patients with preserved (>50%) left ventricular ejection fraction (LVEF) who completed a dobutamine stress echocardiography (DSE), considering target HR. Prospective study of patients with preserved LVEF and CFVR obtained in the LAD who completed DSE. In Group I (GI = 31), normal CFVR was obtained before achieving target HR, and, in Group II (GII = 28), after that. Group III (G III=24) reached target HR, but CFVR was abnormal. Death, acute coronary insufficiency, coronary intervention, coronary angiography without further intervention, and hospitalization were considered events. In 28 ± 4 months, there were 18 (21.6%) events: 6% (2/31) in GI, 18% (5/28) in GII, and 46% (11/24) in GIII. There were 4 (4.8%) deaths, 6 (7.2%) coronary interventions and 8 (9.6%) coronary angiographies without further intervention. In event-free survival by regression analysis, GIII had more events than GI (p < 0.001) and GII (p < 0.045), with no difference between GI and GII (p = 0.160). After adjustment, the only difference was between GIII and GI (p = 0.012). In patients with preserved LVEF and who completed their DSE, normal CFVR obtained before achieving target HR was associated with better prognosis. A reserva de velocidade de fluxo coronariano (RVFC) adequada (≥ 2) obtida na artéria descendente anterior (ADA) através do ecocardiograma transtorácico associa-se a bom prognóstico, mas não há estudo correlacionando-a com a frequência cardíaca (FC) alvo (submáxima).

Beyond "born this way?" reconsidering sexual orientation beliefs and attitudes.

2016-01-01

Previous research on heterosexuals' beliefs about sexual orientation (SO) has been limited in that it has generally examined heterosexuals' beliefs from an essentialist perspective. The recently developed Sexual Orientation Beliefs Scale (SOBS; Arseneau, Grzanka, Miles, & Fassinger, 2013) assesses multifarious "lay beliefs" about SO from essentialist, social constructionist, and constructivist perspectives. This study used the SOBS to explore latent group-based patterns in endorsement of these beliefs in 2 samples of undergraduate students: a mixed-gender sample (n = 379) and an all-women sample (n = 266). While previous research has posited that essentialist beliefs about the innateness of SO predict positive attitudes toward sexual minorities, our research contributes to a growing body of scholarship that suggests that biological essentialism should be considered in the context of other beliefs. Using a person-centered analytic strategy, we found that that college students fell into distinct patterns of SO beliefs that are more different on beliefs about the homogeneity, discreteness, and informativeness of SO categories than on beliefs about the naturalness of SO. Individuals with higher levels of endorsement on all 4 SOBS subscales (a group we named multidimensional essentialism) and those who were highest in discreteness, homogeneity, and informativeness beliefs (i.e., high-DHI) reported higher levels of homonegativity when compared with those who were high only in naturalness beliefs. We discuss the implications of these findings for counseling and psychotherapy about SO, as well educational and social interventions. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Although the Mini-Mental State Examination (MMSE), Clinical Dementia Rating-Sum of Boxes (CDR-SOB), and neuropsychological batteries are widely used for evaluating cognitive function, it remains elusive which instrument best reflects the longitudinal disease progression in amnestic mild cognitive impairment (aMCI) and probable Alzheimer disease (AD). We investigated whether changes in these three instruments over time correlate with loss of cortical gray matter volume (cGMV). We retrospectively investigated 204 patients (aMCI, n = 114; AD, n = 90) who had undergone MMSE, CDR-SOB, the dementia version of the Seoul Neuropsychological Screening Battery (SNSB-D), and 3-dimensional T1-weighted magnetic resonance images at least twice. We investigated the partial correlation between annual decline in test scores and percent change of cGMV. In aMCI patients, changes in the SNSB-D total score (r = 0.340, p < 0.001) and CDR-SOB (r = 0.222, p = 0.020), but not MMSE, showed a correlation with cGMV loss, with the SNSB-D total score showing the strongest correlation. In AD patients, decline in all three test scores correlated significantly with cGMV loss, with MMSE exhibiting the strongest correlation (r = 0.464, p < 0.001). In aMCI patients, neuropsychological battery, though time-consuming, was the most adequate tool in tracking disease progression. In AD patients, however, MMSE may be the most effective longitudinal monitoring tool when considering cost-effectiveness. © 2017 S. Karger AG, Basel.

Limited-oxygen mediated synergistic relationships between sulfate-reducing bacteria (SRB), nitrate-reducing bacteria (NRB) and sulfide-oxidizing bacteria (SOB, including nitrate-reducing, sulfide-oxidizing bacteria NR-SOB) were predicted to simultaneously remove contaminants of nitrate, sulfate and high COD, and eliminate sulfide generation. A lab-scale experiment was conducted to examine the impact of limited oxygen on these oxy-anions degradation, sulfide oxidation and associated microbial functional responses. In all scenarios tested, the reduction of both nitrate and sulfate was almost complete. When limited-oxygen was fed into bioreactors, S(0) formation was significantly improved up to ∼ 70%. GeoChip 4.0, a functional gene microarray, was used to determine the microbial gene diversity and functional potential for nitrate and sulfate reduction, and sulfide oxidation. The diversity of the microbial community in bioreactors was increased with the feeding of limited oxygen. Whereas the intensities of the functional genes involved in sulfate reduction did not show a significant difference, the abundance of the detected denitrification genes decreased in limited oxygen samples. More importantly, sulfide-oxidizing bacteria may alter their populations/genes in response to limited oxygen potentially to function more effectively in sulfide oxidation, especially to elemental sulfur. The genes fccA/fccB from nitrate-reducing, sulfide-oxidizing bacteria (NR-SOB), such as Paracoccus denitrificans, Thiobacillus denitrificans, Beggiatoa sp., Thiomicrospira sp., and Thioalkalivibrio sp., were more abundant under limited-oxygen condition.

To describe respiratory function in a series of patients with late-onset Pompe disease after the definitive diagnosis and before enzyme replacement therapy. This was a cross-sectional study involving patients with a definitive molecular diagnosis of late-onset Pompe disease. The data analyzed included age at symptom onset; age at definitive diagnosis; type of initial symptoms; time from symptom onset to diagnosis; FVC in the sitting and supine positions; six-minute walk distance; and locomotor ability. Analyses were carried out using frequencies, medians, minimum values, and maximum values. Six patients were included in the study. The median age at symptom onset was 15 years (range, 13-50 years), and the median age at diagnosis was 39.5 years (range, 10-64 years). The median time from symptom onset to diagnosis was 8 years (range, 0-45 years). In all cases, the initial manifestation of the disease had been motor weakness. The median FVC in percentage of the predicted value (FVC%) in the sitting and supine positions was 71.0% (range, 22.9-104.6%) and 58.0% (range, 10.9-106.9%), respectively. The median ΔFVC% was 24.5% (range, -4.59 to 52.40%).The median six-minute walk distance was 391.7 m (range, 97-702 m) . In this case series, the time from symptom onset to diagnosis was long. Although respiratory signs or symptoms were not the initial manifestations of the disease, 66.7% of the patients showed reduced FVC% in the sitting and supine positions at diagnosis.

to evaluate pain in patients with lower limb venous ulcer who used non-adherent Ibuprofen foam dressing (IFD). we conducted a prospective study of patients with lower limb venous ulcers treated from April 2013 to August 2014. We used the Numerical Scale and McGill Pain Questionnaire, performing the assessments at the moment of inclusion of the patient in the study and every eight days thereafter, totaling five consultations. We divided the patients into two groups: 40 in the Study Group (SG), who were treated with IFD, and 40 in the Control Group (CG), treated with primary dressing, according to tissue type and exudate. at the first consultation, patients from both groups reported intense pain. On the fifth day, SG patients reported no pain and the majority of CG reported moderate pain. Regarding the McGill Pain Questionnaire, most patients of both groups reported sensations related to sensory, affective, evaluative and miscellaneous descriptors at the beginning of data collection; after the second assessment, there was slight improvement among the patients in the SG. After the third consultation, they no longer reported the mentioned descriptors. CG patients displayed all the sensations of these descriptors until the fifth visit. non-adherent Ibuprofen foam dressing is effective in reducing the pain of patients with venous ulcers. avaliar a dor em pacientes portadores de úlcera venosa de membros inferiores que utilizaram curativo de espuma não aderente com Ibuprofeno (CEI). estudo prospectivo de pacientes portadores de úlceras venosas de membros inferiores tratados no período de abril de 2013 a agosto de 2014.

Salazar, Ricardo; Velez, Carlos E; Royall, Donald R

BACKGROUND/STUDY CONTEXT: There is a need for a simple and reliable screening test to detect individuals with mild cognitive impairment (MCI). The authors analyzed the relationship between performance of the Alzheimer's Questionnaire (AQ), an informant-rated measure of dementia-related behaviors, relative to the Telephone Interview for Cognitive Status-modified (TICS-m), Memory Impairment Scale-telephone version (MIS-t), and the Telephone Executive Assessment (TEXAS) as predictors of MCI. Comparative cross-sectional design, with data collected from participants in the Texas Alzheimer's Research and Care Consortium's (TARCC) San Antonio site. One-hundred percent of our sample was Hispanic. The San Antonio subset of TARCC sample is highly enriched with Mexican Americans (MAs). Fifty-five percent of the interviews were conducted in Spanish. Of the 184 persons enrolled, 124 were normal controls (NCs), and 60 participants had MCI. MCI status and Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) were determined through clinical consensus and performed blind to telephone assessments. Controlling for age, gender, education, and language of interview, the association between telephone measures and CDR-SOB was evaluated by multivariate regression. AQ scores were not affected by education, gender, and language of interview, but subject's age did show a positive correlation with informant AQ ratings. The AQ predicted CDR-SOB independently of the cognitive measures, adding variance above and beyond demographics. The TICS-m and the TEXAS appear to have additive value in improving the detection of cognitively impaired patients. The MIS-t failed to contribute significantly to CDR-SOB, independent of the other measures. The AQ may have utility as a culture-fair telephone screening for MCI. The AQ was able to modestly distinguish MCI from NCs. The TEXAS adds variance to a model of dementia severity independent of the AQ, suggesting that the latter may weakly assess that

Patients with lung cancer experience different feelings and reactions, based on their family, social, cultural, and religious backgrounds, which are a source of great distress, not only for the patients but also for their family caregivers. This study aimed to evaluate the impact that lung cancer stage and quality of life (QoL) of lung cancer patients have on caregiver burden. This was a prospective cross-sectional study. Consecutive patient-caregiver dyads were selected and asked to complete the Hospital Anxiety and Depression Scale and the Medical Outcomes Study 36-item ShortForm Health Survey (SF-36). Family caregivers also completed the Caregiver Burden Scale. Group-based modeling was used in order to identify patients with early- or advanced-stage cancer (IA to IIIA vs. IIIB to IV) plus non-impaired or impaired QoL (SF36 total score > 50 vs. ≤ 50). Patient-caregiver dyads were stratified into four groups: early-stage cancer+non-impaired QoL; advanced-stage cancer+non-impaired QoL; early-stage cancer+impaired QoL; and advanced-stage cancer+impaired QoL. We included 91 patient-caregiver dyads. The majority of the patients were male and heavy smokers. Family caregivers were younger and predominantly female. The burden, QoL, level of anxiety, and level of depression of caregivers were more affected by the QoL of the patients than by their lung cancer stage. The family caregivers of the patients with impaired QoL showed a higher median burden than did those of the patients with non-impaired QoL, regardless of disease stage. Caregiver burden is more affected by patient QoL than by lung cancer stage.

ão geral das evidências científicas sobre a efetividade das intervenções psicossociais no tratamento de transtornos alimentares. Foram incluídas todas as revisões sistemáticas publicadas no Banco de Dados de Revisões Sistemáticas da Cochrane Library. Posteriormente, a partir da data menos recente destas revisões (2001), realizou-se uma busca adicional no PubMed, com estratégia de busca sensibilizada e com os mesmos descritores utilizados antes. No total, foram incluídos 101 estudos primários e 30 revisões sistemáticas (5 revisões sistemáticas da Cochrane), metanálises, diretrizes ou revisões narrativas da literatura. Os principais desfechos foram remissão de sintomas, imagem corporal, distorção cognitiva, comorbidade psiquiátrica, funcionamento psicossocial e satisfação do paciente. A abordagem cognitivo-comportamental foi o tratamento mais efetivo, principalmente para bulimia nervosa, transtorno da compulsão alimentar periódica e síndrome do comer noturno. Para anorexia nervosa, a abordagem familiar demonstrou maior efetividade. Outras abordagens efetivas foram psicoterapia interpessoal, terapia comportamental dialética, terapia de apoio e manuais de autoajuda. Além disso, houve um número crescente de abordagens preventivas e promocionais que contemplaram fatores de risco individuais, familiares e sociais, sendo promissoras para o desenvolvimento da autoimagem positiva e autoeficácia. São necessários mais estudos que avaliem o impacto de abordagens multidisciplinares em todos transtornos alimentares, além da relação custo-efetividade de algumas modalidades efetivas, como a terapia cognitivo-comportamental.

This is a 78 year old male with a past medical history of coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD), hypertension (HTN), and gastroesophageal reflux disorder (GERD) who presented to the emergency room with worsening shortness of breath (SOB) and low-grade fevers for one week prior to admission. He was originally diagnosed with healthcare associated pneumonia (HCAP) and an acute on chronic COPD exacerbation and treated with prednisone, inhalers, ipratropium/albuterol, and broad-spectrum antibiotics. His symptoms were slow to respond to therapy and he continued to have end-expiratory wheezes with persistent SOB. A CT of his chest was ordered to rule out a possible pulmonary embolus (PE) and instead showed an obstructing mass in the bronchus. Pulmonology was consulted and performed a bronchoscopy, which revealed a foreign body (bean) causing the obstruction, which was removed, and the patient's symptoms improved shortly thereafter.

Structure and function of natural sulphide-oxidizing microbial mats under dynamic input of light and chemical energy

We studied the interaction between phototrophic and chemolithoautotrophic sulphide-oxidizing microorganisms in natural microbial mats forming in sulphidic streams. The structure of these mats varied between two end-members: one characterized by a layer dominated by large sulphur-oxidizing bacteria (SOB; mostly Beggiatoa-like) on top of a cyanobacterial layer (B/C mats) and the other with an inverted structure (C/B mats). C/B mats formed where the availability of oxygen from the water column was limited (<5 μm). Aerobic chemolithotrophic activity of the SOB depended entirely on oxygen produced locally by cyanobacteria during high light conditions. In contrast, B/C mats formed at locations where oxygen in the water column was comparatively abundant (>45 μM) and continuously present. Here SOB were independent of the photosynthetic activity of cyanobacteria and outcompeted the cyanobacteria in the uppermost layer of the mat where energy sources for both functional groups were concentrated. Outcompetition of photosynthetic microbes in the presence of light was facilitated by the decoupling of aerobic chemolithotrophy and oxygenic phototrophy. Remarkably, the B/C mats conserved much less energy than the C/B mats, although similar amounts of light and chemical energy were available. Thus ecosystems do not necessarily develop towards optimal energy usage. Our data suggest that, when two independent sources of energy are available, the structure and activity of microbial communities is primarily determined by the continuous rather than the intermittent energy source, even if the time-integrated energy flux of the intermittent energy source is greater.

ça arterial coronariana (DAC) com base em variáveis avaliadas à admissão na unidade coronariana (UC) devido a dor torácica aguda. Foram estudados um total de 470 pacientes, 370 utilizados como amostra de derivação e os subsequentes 100 pacientes como amostra de validação. Como padrão de referência, a angiografia foi necessária para descartar DAC (estenose ≥ 70%), enquanto a angiografia ou um teste não invasivo negativo foi utilizado para confirmar a doença. Foram testadas como preditoras 13 variáveis basais relacionadas à história médica, 14 características de desconforto torácico e oito variáveis relacionadas ao exame físico ou testes laboratoriais. A prevalência de DAC foi de 48%. Por regressão logística, seis variáveis permaneceram como preditoras independentes de DAC: idade, gênero masculino, alívio com nitrato, sinais de insuficiência cardíaca, e eletrocardiograma e troponina positivos. A área sob a curva (area under the curve, AUC) deste modelo final foi de 0,80 (intervalo de confiança de 95% [IC95%] = 0,75 - 0,84) na amostra de derivação e 0,86 (IC95% = 0,79 - 0,93) na amostra de validação. O teste de Hosmer-Lemeshow indicou uma boa calibração em ambas as amostras (p = 0,98 e p = 0,23, respectivamente). Em comparação com o modelo básico contendo eletrocardiograma e troponina, o modelo completo ofereceu um incremento na AUC de 0,07 tanto na amostra de derivação (p = 0,0002) quanto na de validação (p = 0,039). A melhoria na discriminação integrada foi de 0,09 nas amostras de derivação (p < 0,001) e validação (p < 0,0015). Um modelo multivariado foi derivado e validado como uma ferramenta acurada para estimar a probabilidade pré-teste de DAC em pacientes com dor torácica aguda.

Treatment engagement, retention and adherence to care are required for optimal HIV outcomes. Yet, patients may fall below the treatment recommendations for achieving undetectable viral load or not be retained in care. This study examined the most challenging patients in Buenos Aires, Argentina, those non-adherent to HIV care. Men (n = 61) and women (n = 59) prescribed antiretrovirals (ARVs) and non-adherent to treatment in the prior 3 to 6 months were enrolled and assessed regarding adherence, knowledge, motivation and attitudes regarding treatment. Private clinic patients had lower viral load and higher self-reported adherence than public clinic patients. Motivations to be adherent and positive beliefs regarding ARVs were associated with increased adherence in public clinic participants. Increased self-efficacy was associated with increased adherence among participants from both clinics. Results support patient and provider interventions that strengthen the characteristics supporting adherence, engagement and retention in public and private clinic settings. Resumen El compromiso, la retención en el cuidado y adherencia al tratamiento son esenciales para el manejo óptimo del paciente con VIH.

O grau de escolaridade e a renda mensal não se mostraram relevantes em relação ao conhecimento de cuidados preventivos do PD e nem uma maior adesão a hábitos de vida saudáveis. O cuidado com o PD tende a melhorar à medida que exista uma compreensão mais clara dos fatores que conduzem à perda do membro e um crescente consenso sobre a gestão de vários aspectos clínicos do cuidado com o pé. Conclusão Existe uma falta de aprendizado das medidas preventivas, mesmo nos pacientes com algum nível de instrução, o que induz a uma prática deficiente de cuidados.

Sarcopenic obesity or obese sarcopenia: A cross talk between age-associated adipose tissue and skeletal muscle inflammation as a main mechanism of the pathogenesis.

PubMed

Kalinkovich, Alexander; Livshits, Gregory

2017-05-01

Sarcopenia, an age-associated decline in skeletal muscle mass coupled with functional deterioration, may be exacerbated by obesity leading to higher disability, frailty, morbidity and mortality rates. In the combination of sarcopenia and obesity, the state called sarcopenic obesity (SOB), some key age- and obesity-mediated factors and pathways may aggravate sarcopenia. This review will analyze the mechanisms underlying the pathogenesis of SOB. In obese adipose tissue (AT), adipocytes undergo hypertrophy, hyperplasia and activation resulted in accumulation of pro-inflammatory macrophages and other immune cells as well as dysregulated production of various adipokines that together with senescent cells and the immune cell-released cytokines and chemokines create a local pro-inflammatory status. In addition, obese AT is characterized by excessive production and disturbed capacity to store lipids, which accumulate ectopically in skeletal muscle. These intramuscular lipids and their derivatives induce mitochondrial dysfunction characterized by impaired β-oxidation capacity and increased reactive oxygen species formation providing lipotoxic environment and insulin resistance as well as enhanced secretion of some pro-inflammatory myokines capable of inducing muscle dysfunction by auto/paracrine manner. In turn, by endocrine manner, these myokines may exacerbate AT inflammation and also support chronic low grade systemic inflammation (inflammaging), overall establishing a detrimental vicious circle maintaining AT and skeletal muscle inflammation, thus triggering and supporting SOB development. Under these circumstances, we believe that AT inflammation dominates over skeletal muscle inflammation. Thus, in essence, it redirects the vector of processes from "sarcopenia→obesity" to "obesity→sarcopenia". We therefore propose that this condition be defined as "obese sarcopenia", to reflect the direction of the pathological pathway. Copyright © 2016 Elsevier B.V. All rights

Introducción: la desnutrición intrahospitalaria se ha descrito hace más de 70 años como un problema frecuente. En México se reportan cifras de entre el 20% al 50%; sin embargo no se ha estudiado su prevalencia ni su asociación con la morbilidad y mortalidad hospitalaria.Objetivos: evaluar el estado nutricional y su relación con la morbimortalidad hospitalaria en pacientes mexicanos.Métodos: cohorte prospectiva de pacientes que ingresaron en un hospital de referencia para una estancia hospitalaria mayor de 5 días. Se capturó peso, talla, índice de masa corporal (IMC), estado nutricional de acuerdo con la valoración global subjetiva (VGS) a su ingreso y egreso hospitalario, así como diagnóstico médico, complicaciones y mortalidad. Los datos fueron analizados mediante la prueba T de Student, prueba Chi-cuadrado y prueba Exacta de Fisher.Resultados: se incluyeron 610 pacientes en total, con un promedio de edad de 50,8 ± 17,32 años, 267 mujeres (43,8%) y 343 hombres (56,2%). Del total, 154 fueron catalogados con sospecha de desnutrición o desnutrición (pacientes expuestos, 25,2%) y 456 bien nutridos (pacientes no expuestos, 74,8%), con una relación de 1 a 3. La morbilidad total de la cohorte tuvo un RR = 2,70, IC 95 % (2,06-3,55) y la mortalidad con un RR = 2,64, IC 95% (1,74-4,0), siendo ambas estadísticamente significativas (p = 0,001).Conclusiones: el diagnóstico de desnutrición al ingreso hospitalario constituye un factor de riesgo para el desarrollo de complicaciones y mortalidad. Este padecimiento al ingreso en comparación con el paciente que no presenta desnutrición incrementó el riesgo de mortalidad hasta en 2.64 veces.

Introducción: conociendo la elevada prevalencia de la desnutrición hospitalaria, se hace necesaria su detección precoz. Cuando, por diversos motivos, no es posible realizar una valoración completa del estado nutricional, se recomienda el empleo de herramientas validadas de cribado nutricional. Estas ayudarían a detectar de forma rápida a aquellos pacientes que necesiten de un tratamiento nutricional.Objetivos: determinar la prevalencia del riesgo de desnutrición, en el Hospital General Universitario de Valencia, empleando para ello la herramienta de cribado nutricional HEMAN y comprobar si la implementación de esta herramienta en la práctica clínica, sería lo más adecuado.Métodos: estudio transversal, realizado sobre una muestra de 1.099 pacientes ingresados en un hospital terciario. A todos ellos se les realizó el cribado nutricional HEMAN a las 24-48 horas del ingreso. Las variables cualitativas se compararon mediante Chi-cuadrado, y las cuantitativas mediante el test t de Student.Resultados: la prevalencia del riesgo de desnutrición fue del 33,5%. Los pacientes que resultaron positivos en el cribado (HEMAN ≥ 3), tenían mayor edad que los pacientes normonutridos, referían pérdidas de peso entre el 5-10%, el 55,2% disminuyó su ingesta a menos del 50% de la habitual. Además, ingresaron con patologías consideradas de leves a moderadas. La utilización del método HEMAN como herramienta de cribado, resultó ser práctica y efectiva, y ayudó a disminuir el tiempo empleado con cada paciente encuestado evaluado.Conclusiones: se detectó una elevada prevalencia de riesgo de desnutrición entre los pacientes evaluados, por lo tanto se hace imprescindible la utilización de métodos de cribado nutricional en la rutina diaria del hospital, para ello recomendamos especialmente la utilización del método HEMAN.

To identify the prevalence of patients suspected of drug use according to the nursing professionals' judgement, and compare the behavior of these professionals in opioid administration when there is or there is no suspicion that patient is a drug user. A cross-sectional study with 507 patients and 199 nursing professionals responsible for administering drugs to these patients. The Chi-Square test, Fisher's Exact and a significance level of 5% were used for the analyzes. The prevalence of suspected patients was 6.7%. The prevalence ratio of administration of opioid analgesics 'if necessary' is twice higher among patients suspected of drug use compared to patients not suspected of drug use (p = 0.037). The prevalence of patients suspected of drug use was similar to that of studies performed in emergency departments. Patients suspected of drug use receive more opioids than patients not suspected of drug use. Identificar a prevalência de pacientes com suspeita de uso de drogas conforme opinião de profissionais de enfermagem e comparar a conduta desses profissionais na administração de opioides quando há ou não suspeita de que o paciente seja usuário de drogas. Estudo transversal com 507 pacientes e 199 profissionais de enfermagem responsáveis pela administração de medicamentos a esses pacientes. Para as análises foram utilizados os testes de Qui-Quadrado, Exato de Fisher e um nível de significância de 5%. A prevalência de pacientes suspeitos foi 6,7%. A razão de prevalência de administração de analgésicos opioides "se necessário" é duas vezes maior entre os pacientes suspeitos em relação aos não suspeitos (p=0,037). A prevalência de suspeitos foi semelhante à de estudos realizados em departamentos de emergência. Os suspeitos de serem usuários de drogas recebem mais opioides do que os não suspeitos.

Resumen Objetivo: El propósito del presente trabajo es presentar los resultados de 16 pacientes con diagnóstico de hemangioblastoma de fosa posterior (HBFP), operados con técnicas microquirúrgicas. Método: Desde junio de 2005 a diciembre de 2015, 16 pacientes con diagnóstico de HBFP fueron intervenidos quirúrgicamente. Se evaluó: sexo, edad, tipo de lesión (quística con nódulo, quística sin nódulo, sólida y sólida-quística), sintomatología y resultados postoperatorios. Resultados: De los 16 pacientes intervenidos, 11 fueron varones y 5 mujeres. La edad promedio fue de 44 años. La forma más frecuente fue quística con nódulo (57%), seguida por forma sólida (31%). Un solo caso presentó la forma quística sin nódulo (6%), y uno solo la forma sólido-quística (6%). La sintomatología más frecuente fue cefalea acompañada de síndrome cerebeloso (43%), seguido de síndrome de hipertensión endocraneana (25%). En todos los casos la resección fue completa, siendo necesario en un caso una embolización previa. Como complicaciones postoperatorias, 2 pacientes presentaron ataxia (mejoró al cabo de 3 meses), y 1 paciente presentó una fístula de LCR (se solucionó con un drenaje espinal externo). Se registró un óbito por complicaciones postoperatorias. Conclusión: Lo más frecuente de ver en pacientes con HBFP es la forma quística con nódulo, siendo su sintomatología predominante la cefalea acompañada de síndrome cerebeloso. La resección quirúrgica completa es posible, con una baja tasa de morbimortalidad. PMID:27999708

Objetivos: estimar el porcentaje de pacientes con EPOC adiestrados en la consulta para el manejo de inhaladores en la provincia de León.Métodos: estudio epidemiológico, transversal, multicéntrico (30 centros de salud de la provincia de León). Incluyó pacientes mayores de 35 años diagnosticados y tratados de EPOC. Variables a estudio: edad, sexo, hábitat, datos antropométricos, estado nutricional, tabaquismo, espirometría postboroncodilatadora, disnea (mMRC), reagudizaciones, gravedad (Índice Bodex), hospitalizaciones, tratamiento, seguimiento y caracterización del fenotipo (GesEOPC 2014). Los resultados se expresan con sus IC al 95,5%.Resultados: se incluyeron 833 pacientes, el 85,8% varones, con edad media de 64,69 (53,66-75,61) años y 20,65 (4,47-36,8) años evolución de la EPOC. Empleaban 1,88 (1,64-2,16) dispositivos inhaladores de media, p = 0,006, (57% de forma correcta, 23% regular y el 20% incorrecta). El 20,9% no recibieron adiestramiento para usar inhaladores frente al 79,1% adiestrados, p < 0,001, (9,4% por neumólogos, 20,3% enfermeras y 43,5% médicos familia, p = 0,002). Los pacientes bien adiestrados realizan mejor el tratamiento, en el 60,60% (58,91-62,29), p = 0,002. No hubo diferencias significativas en el adiestramiento por tabaquismo, gravedad, ingresos hospitalarios, ni calidad de vida, obteniendo una reducción significativa del número de agudizaciones, siendo de 1,59 (1,12-2,15) reagudizaciones medias en el grupo adiestrado frente a 3,29 (2,50-4,11) en los no adiestrados, p = 0,002.Conclusiones: el nivel de adiestramiento en el uso de inhaladores en los pacientes con EPOC es insuficiente en nuestro medio. La mejor formación de los profesionales y la simplificación de los dispositivos contribuirán a que un mayor número de pacientes realicen el tratamiento de forma adecuada.

Objetivo: El propósito del presente trabajo es presentar los resultados de 13 pacientes con diagnóstico de espasmo hemifacial (EHF), en los cuales se realizó una descompresión microvascular (DMV). Material y Método: Desde Junio de 2005 a Mayo de 2014, 13 pacientes con diagnóstico de EHF fueron intervenidos quirúrgicamente, realizando una DMV. Se evaluó: edad, sexo, tiempo de evolución de la sintomatología, hallazgos intraoperatorios y resultados postoperatorios. Resultados: De los 13 pacientes intervenidos, 7 fueron mujeres y 6 varones. La media de edad fue de 53 años. El tiempo medio entre el inicio de la sintomatología y la intervención quirúrgica osciló entre 3 y 9 años. En todos los casos el EHF era típico, uno de ellos con neuralgia trigeminal concomitante, observándose en todos compresión neurovascular intraoperatoria. Por orden decreciente de frecuencia la causa de la compresión fue arteria cerebelosa anteroinferior, arteria cerebelosa posteroinferior, arteria dolicomega basilar y arteria dolicomega vertebral. El seguimiento postoperatorio fue en promedio de 24 meses. El 62% presentó desaparición postquirúrgica inmediata de la sintomatología preoperatoria, el 30% desaparición tras un período de 3 semanas a 2 meses (8% con mejoría parcial), y en el 8% no hubo mejoría. En cuanto a las complicaciones postoperatorias: 3 pacientes presentaron paresia facial II-III en la escala de House-Brackman (se recuperaron en un período de 6 meses), y 1 paciente presentó fístula de líquido cefalorraquídeo. Ninguno de los pacientes de la serie presentaron hipoacusia transitorio o permanente. Conclusión: La DMV como tratamiento del EHF es un procedimiento efectivo y seguro, que permite la resolución completa de la patología en la mayoría de los casos. PMID:27127708

The aim of the present research was to investigate cognitive pattern of patients with neuromyelitis optica (NMO) and to compare it with multiple sclerosis (MS) patients' performance. Fourteen NMO, 14 relapsing remitting multiple sclerosis (RRMS), and 14 healthy control patients participated in the investigation. Neuropsychological functions were evaluated with the Brief Repeatable Neuropsychological Battery for MS; Symbol Digit Modalities Test; Digit Span; and Semantic Fluency. Fifty-seven percent of NMO patients and 42.85% of the MS ones had abnormal performance in at least two cognitive tests. The NMO Group showed abnormal performance in verbal fluency, verbal and visual memories, with greater attention deficits. NMO patients outperformed healthy control in the paced auditory serial addition test (PASAT). However, no difference was found between NMO and RRMS patients. The NMO Group showed more dysfunction in attention and verbal fluencies than in verbal and visual memories. When compared with the MS patients, a similar dysfunction pattern was found. O objetivo da presente pesquisa foi investigar o padrão cognitivo de pacientes com neuromielite óptica (NMO) e compará-lo com o desempenho de pacientes com esclerose múltipla (EM).

Does Plan B work? Home range estimations from stored on board and transmitted data sets produced by GPS-telemetry in the Colombian Amazon.

Telemetry based on Global Positioning Systems (GPS) makes possible to gather large quantities of information in a very fine scale and work with species that were impossible to study in the past. When working with GPS telemetry, the option of storing data on board could be more desirable than the sole satellite transmitted data, due to the increase in the amount of locations available for analysis. Nonetheless, the uncertainty in the retrieving of the collar unit makes satellite-transmitted technologies something to take into account. Therefore, differences between store-on-board (SoB) and satellite-transmitted (IT) data sets need to be considered. Differences between SoB and IT data collected from two lowland tapirs (Tapirus terrestris), were explored by means of the calculation of home range areas by three different methods: the Minimum Convex Polygon (MCP), the Fixed Kernel Density Estimator (KDE) and the Brownian Bridges (BB). Results showed that SoB and IT data sets for the same individual were similar, with fix ranging from 63 % to 85 % respectively, and 16 m to 17 m horizontal errors. Depending on the total number of locations available for each individual, the home ranges estimated showed differences between 2.7 % and 79.3 %, for the 50 % probability contour and between 9.9 % and 61.8 % for the 95 % probability contour. These differences imply variations in the spatial coincidence of the estimated home ranges. We concluded that the use of IT data is not a good option for the estimation of home range areas if the collar settings have not been designed specifically for this use. Nonetheless, geographical representations of the IT based estimators could be of great help to identify areas of use, besides its assistance to locate the collar for its retrieval at the end of the field season and as a proximate backup when collars disappear.

Identification and distribution of sulfate reducing bacteria and sulphur-oxidising bacteria in northern South China Sea

NASA Astrophysics Data System (ADS)

Mao, S.; Zhu, X.; Guan, H.; Wu, D.; Wu, N.

Fatty acids are one of the major components in modern marine sediments. It is well known that the saturated short-chain FAs were typically to be from vascular plants, algae, bacteria, and other sources, while the saturated long-chain FAs are the major components found in leaf waxes, suberin, and cutin in terrestrial higher plants. So the lipid biomarkers of fatty acids in Site 4B from Shenhu Area, northern South China Sea were investigated in Recent research supported from the 973 Program (2009CB219506), and the resources of branched fatty acids and monounsaturated fatty acids were mainly discussed. The results reveal that i/a15:0, i/a17:0, 16:1ω5, 18:1ω9 and 10me16:0 are derived from sulfate reducing bacteria (SRB), while 16:1ω7t/c and 18:1ω7 are originated from sulphur-oxidising bacteria (SOB). The biomakers of methanotrophs such as 16:1ω6/8 and 18:1ω6/8 were not detected in the sediments which coincide with more positive carbon isotope values of the fatty acids in the sediments. The stable relationship between SRB and SOB below 97cm in the sediments reflects the relative stable oxidative and reductive depositional environment which may be connected with the sulphur cycle in the sediments, that is carried out as sulfate is reduced to sulfide, and then sulfide is oxidized to sulfate and elemental sulfur, at last elemental sulfur is disproportionated to sulfide and sulfate. The frequently changed relationship of SRB and SOB above 97cm in the sediments indicates intensely changing oxidative and reductive sedimental environment, that may related with diapir structure around Site 4B, which also brings about hydrocarbon seepage leading to increasing biomass at 97cm.

Forgetting in immediate serial recall: decay, temporal distinctiveness, or interference?

PubMed

Oberauer, Klaus; Lewandowsky, Stephan

2008-07-01

Three hypotheses of forgetting from immediate memory were tested: time-based decay, decreasing temporal distinctiveness, and interference. The hypotheses were represented by 3 models of serial recall: the primacy model, the SIMPLE (scale-independent memory, perception, and learning) model, and the SOB (serial order in a box) model, respectively. The models were fit to 2 experiments investigating the effect of filled delays between items at encoding or at recall. Short delays between items, filled with articulatory suppression, led to massive impairment of memory relative to a no-delay baseline. Extending the delays had little additional effect, suggesting that the passage of time alone does not cause forgetting. Adding a choice reaction task in the delay periods to block attention-based rehearsal did not change these results. The interference-based SOB fit the data best; the primacy model overpredicted the effect of lengthening delays, and SIMPLE was unable to explain the effect of delays at encoding. The authors conclude that purely temporal views of forgetting are inadequate. Copyright (c) 2008 APA, all rights reserved.

Avaliou-se 216 pacientes, com as seguintes características: sexo feminino (68,1%), faixa etária entre 30-40 anos, com 31,9% e 31%, respectivamente. De acordo com o IMC, 17,6% apresentavam obesidade moderada, 82,4% obesidade severa/mórbida e 9,7% superobesidade. Nos pacientes submetidos à endoscopia, a positividade do H. pylori se manifestou em 40,7%, sendo responsável pela atividade inflamatória na mucosa gástrica (p<0,001). No pós-operatório, investigou-se a mucosa gástrica através de endoscopia e histopatologia no 6° e 12° mês, que demonstrou normalidade no neorreservatorio gástrico em 84% dos pacientes, e a incidência de H. pylori foi 11% aos seis meses e 16% aos 12 meses, sendo a presença de processo inflamatório relacionado com a infecção pela bactéria (p<0,001). - H. pylori apresenta prevalência similar tanto em obesos que irão submeter-se à cirurgia bariátrica quanto à população em geral; há baixa incidência dele no 6° e 12° mês após a operação e isto deve-se provavelmente à sua erradicação quando detectado no pré-operatório; quando presente a doença inflamatória no neorreservatório gástrico possui relação direta com a infecção por H. pylori.

measure and compare the quality of life of neurogenic bladder patients using intermittent urinary catheterization who were going through rehabilitation in Brazil and Portugal. multicenter, quantitative, cross-sectional, observational-analytic and correlational study executed in Brazil and Portugal. Two data collection tools were used, being one questionnaire with sociodemographic and clinical data and the World Health Organization Quality of Life-bref. Patients were included who were over 18 years of age, suffering from neurogenic urinary bladder and using intermittent urinary catheterization. in the sample of Brazilian (n = 170) and Portuguese (n = 52) patients, respectively, most patients were single (87-51.2%; 25-48.1%), had finished primary education (47-45.3%; 31-59.6%) and were retired (70-41.2%; 21-40.4%). Spinal cord injury was the main cause of using the urinary catheter in both countries. The Brazilian patients presented higher mean quality of life scores in the psychological domain (68.9) and lower scores in the physical domain (58.9). The Portuguese patients presented higher scores in the psychological domain (68.4) and lower scores in the environment domain (59.4). The execution of intermittent urinary self-catheterization was significant for both countries. in the two countries, these patients' quality of life can be determined by the improvement in the urinary symptoms, independence, self-confidence, social relationships and access to work activities. mensurar e comparar a qualidade de vida de pacientes com bexiga neurogênica em uso do cateterismo urinário intermitente em processo de reabilitação, no Brasil e em Portugal. estudo multicêntrico, Brasil e Portugal, quantitativo, transversal, observacional-analítico e correlacional.

To determine whether COPD severity correlates with sputum cell counts, atopy, and asthma. This was a cross-sectional study involving 37 patients with COPD and 22 healthy subjects with normal lung function (controls). Sputum cell counts were determined by microscopy after centrifugation of samples. Skin prick tests were performed, and serum cytokines were determined by ELISA. Patients were stratified by bronchodilator response: a non-reversible airflow limitation (nonRAL) group comprised 24 patients showing no significant post-bronchodilator change in FEV1; and a partially reversible airflow limitation (partialRAL) group comprised 13 patients showing FEV1 reversibility (post-bronchodilator FEV1 increase ≥ 12%). The proportion of eosinophils in sputum was higher in the partialRAL group than in the nonRAL group (p < 0.01), and there was an inverse correlation between the proportion of eosinophils and FEV1 (p < 0.05). However, none of the patients had a history of asthma and skin prick test results did not differ between the two groups. In the patient sputum samples, neutrophils predominated. Serum levels of TNF, IL-6, IL-8, and RANTES (CCL5) were higher in patients than in controls (p < 0.001) but did not differ between the two patient groups. COPD patients with partial FEV1 reversibility appear to have higher sputum eosinophil counts and greater airway hyperresponsiveness than do those with no FEV1 reversibility. However, we found that COPD severity did not correlate with atopy or with the cytokine profile. Determinar se a gravidade da DPOC se correlaciona com a contagem de células no escarro, atopia e asma.

New findings point out that the mechanism of formation of the hernias can be related to the collagenous tissues, under activity of aggressive agents such as the tobacco, alcohol and diabetes. To analyze the collagen present in the cremaster muscle in patients with inguinal hernias, focusing the effect of tobacco, alcohol, and diabetes. Fifteen patients with inguinal hernia divided in three groups were studied: group I (n=5) was control; group II (n=5) were smokers and/or drinkers; and group III (n=5) had diabetes mellitus. All subjects were underwent to surgical repair of the inguinal hernias obeying the same pre, intra and postoperative conditions. During surgery, samples of the cremaster muscle were collected for analysis in polarized light microscopy, collagen morphometry and protein. The area occupied by the connective tissue was higher in groups II and III (p<0.05). The collagen tissue occupied the majority of the samples analyzed in comparison to the area occupied by muscle cells. The content of total protein was higher in groups II and III compared to the control group (p<0.05). The tobacco, alcohol and diabetes cause a remodel the cremaster muscle, leading to a loss of support or structural change in this region, which may enhance the occurrences and damage related to inguinal hernias.

to compare the intensity of reflex sweating with the degree of anxiety and its interference in the quality of life of patients undergoing Thoracoscopic (VATS) sympathectomy in the pre- and postoperative period. we evaluated 54 patients with a mean age of 26 years (16-49 years) undergoing sympathectomy in the R3-R4 level. We applied two questionnaires at three different times: "Quality of life in patients with primary hyperhidrosis" and "Scale for anxiety and depression". of the patients studied, 93% showed significant improvement in quality of life 30 days after surgery, the effects remaining after six months. There were no postoperative complications. The patient's level of anxiety is highly correlated with the intensity of reflex sweating after 30 and 180 days. Thoracoscopic sympathectomy improves quality of life of patients with primary hyperhidrosis, even with the emergence of reflex sweating. Anxiety directly relates to the intensity of reflex sweating, without compromising the degree of patient satisfaction. avaliar a intensidade de sudorese reflexa com o grau de ansiedade e sua interferência na qualidade de vida de indivíduos submetidos à simpatectomia por videotoracoscopia nos períodos pré e pós-operatório. foram avaliados 54 pacientes com média de idade de 26 anos (16 a 49 anos), submetidos à simpatectomia em nível R3-R4.

Pancreatic adenocarcinoma remains one of the worst digestive cancers. Surgical resection is the main target when treating a patient with curative intent. To assess angiolymphatic invasion as a prognostic factor in resected pN0 pancreatic cancer. Thirty-eight patients were submitted to pancreatoduodenectomy due to head pancreatic cancer. Tumor size, margins, lymph nodes, pTNM staging, angiolymphatic and perineural invasion were described in the pathologists' reports. Most patients were female. Overall median survival was 13 months. Gemcitabine was the regimen of choice for chemotherapy in selected patients; however, it did not improve overall survival. pR0 resection had better survival compared with pR1. Within the pN0 group, survival was significantly better in patients without angiolymphatic invasion. Angiolymphatic invasion in N0 pancreatoduodenectomy can be demonstrated by the Hematoxylin-Eosin stain and may predict a poor prognosis factor for those patients. Adenocarcinoma pancreático continua sendo um dos piores cânceres do aparelho digestivo. A ressecção cirúrgica é o principal objetivo quando se trata de intenção curativa.

os casos novos de tuberculose pulmonar que completaram com sucesso o tratamento (com ou sem cura confirmada) foram selecionados e seguidos até 31 de dezembro de 2012. Dos 963 casos, RTB ocorreu em 47 (4,88%). O tempo médio transcorrido até o segundo episódio foi de 36,12 meses. Dos 47 casos de RTB, 16 (34,04%) ocorreram em até 18 meses da alta do primeiro tratamento (RTB recente), e 31 (65,96%) ocorreram após 18 meses (RTB tardia). Entre as variáveis investigadas, somente houve diferenças significativas entre os grupos RTB recente e tardia em relação ao ganho de peso na alta do primeiro tratamento (1,78 kg vs. 5,31 kg; p < 0,045) e nível de escolaridade (≤ 3 vs. > 3 anos de estudo; p < 0,004). A baixa escolaridade pode indicar uma menor adesão ao tratamento, dificultando a esterilização dos bacilos e facilitando sua sobrevivência em forma dormente, o que mascara a efetividade do tratamento. A ausência ou um reduzido aumento de peso na alta do tratamento poderá servir como um marcador biológico que pode ser utilizado pelos serviços de saúde que realizam o tratamento de tuberculose.

To identify the association between blood pressure control and the following variables: a) bio-social and lifestyle characteristics of hypertensive patients; and b) factors related to the antihypertensive treatment. This is an exploratory study with 290 people with hypertension from primary care. We used a specific instrument, self-administered, with 21 questions on factors that can hinder treatment, divided into four dimensions: medication, socioeconomic, institutional and personal beliefs. We adopted a significance level of p <0.05. The control of blood pressure was associated (p <0.05) with female gender, Caucasian ethnicity, primary/secondary education, not drinking alcohol, higher income and regular physical activity. Regarding the factors that can hinder treatment, there was association of hypertension control with only two questions: "feel nothing" and "have to do treatment for life". Sociodemographic variables and beliefs concerning the absence of symptoms and chronicity of the disease influenced the control of hypertension and should be considered in the adherence process to the treatment.

La atención nutricional en el paciente oncohematológico debe formar parte del tratamiento global del paciente. Las alteraciones debidas a la localización de la neoplasia y los efectos secundarios del tratamiento oncoespecífico muchas veces dificultan o impiden la alimentación oral. Esto puede dar lugar a una desnutrición y es de gran importancia su detección, valoración e intervención temprana. El primer paso en la intervención nutricional es el consejo dietético. Este artículo muestra qué aspectos deben tenerse en cuenta para poder elaborar un consejo dietético y la importancia de que este sea individualizado. Se describen como ejemplo cuatro situaciones especiales, donde es necesario trasladar las recomendaciones nutricionales a un plan dietético. También se incide en el uso de los probióticos en pacientes inmunocomprometidos.

Chagas disease (CD) is an important cause of heart failure and mortality, mainly in Latin America. This study evaluated the morphological and functional characteristics of the heart as well the extent of myocardial fibrosis (MF) in patients with CD by cardiac magnetic resonance (CMR). The prognostic value of MF evaluated by myocardial-delayed enhancement (MDE) was compared with that via Rassi score. This study assessed 39 patients divided into 2 groups: 28 asymptomatic patients as indeterminate form group (IND); and symptomatic patients as Chagas Heart Disease (CHD) group. All patients underwent CMR using the techniques of cine-MRI and MDE, and the amount of MF was compared with the Rassi score. Regarding the morphological and functional analysis, significant differences were observed between both groups (p < 0.001). Furthermore, there was a strong correlation between the extent of MF and the Rassi score (r = 0.76). CMR is an important technique for evaluating patients with CD, stressing morphological and functional differences in all clinical presentations. The strong correlation with the Rassi score and the extent of MF detected by CMR emphasizes its role in the prognostic stratification of patients with CD.

Shortness of breath in clinical practice: A case for left atrial function and exercise stress testing for a comprehensive diastolic heart failure workup

The symptom cluster of shortness of breath (SOB) contributes significantly to the outpatient workload of cardiology services. The workup of these patients includes blood chemistry and biomarkers, imaging and functional testing of the heart and lungs. A diagnosis of diastolic heart failure is inferred through the exclusion of systolic abnormalities, a normal pulmonary function test and normal hemoglobin, coupled with diastolic abnormalities on echocardiography. Differentiating confounders such as obesity or deconditioning in a patient with diastolic abnormalities is difficult. While the most recent guidelines provide more avenues for diagnosis, such as incorporating the left atrial size, little emphasis is given to understanding left atrial function, which contributes to at least 25% of diastolic left ventricular filling; additionally, exercise stress testing to elicit symptoms and test the dynamics of diastolic parameters, especially when access to the “gold standard” invasive tests is lacking, presents clinical translational gaps. It is thus important in diastolic heart failure work up to understand left atrial mechanics and the role of exercise testing to build a comprehensive argument for the diagnosis of diastolic heart failure in a patient presenting with SOB.

Hydrogen sulphide (H2S) contributes a lot to odours at landfills, which is a threat to the environment and the health of the staff therein. To mitigate its emission, the bioconversion within landfill cover soils (LCSs) was introduced. H2S emission and concentration both in the field air above the landfill and in microcosm testing were surveyed. Results indicated that H2S emission and concentration in the landfill varied with landfill seasons and sites. There existed relationship between H2S concentration and fluxes spatially and temporally. To characterize and assess the spatial and temporal diversity of sulphur-oxidizing bacteria (SOB) and sulphate-reducing bacteria (SRB) in the LCSs, the terminal-restriction fragment length polymorphism technique was employed. Using the functional genes of dsrB and soxB, SOB, including Halothiobacillus, Rhodothalassium, Paracocccus, Allochromatium, and Thiobacillus, and SRB, including Desulfovibrio, Syntrophobacter, Desulfomonile and Desulfobacca, were identical and exhibited the dominant role in the LCSs. By employing an alternative available corona reactor, more than 90% removal efficiencies of sulphides were demonstrated, suggesting that the LCSs for eliminating odours in a lower concentration would be feasible.

2012-01-01

Background Although Coragyps atratus has been used as a traditional therapy for patients with cancer, the scientific literature does not contain enough information on how this therapy is used or the mechanisms that explain this therapeutic practice. Objectives To understand the methods of use and the reasons given by patients and caregivers for the use of Coragyps atratus in cancer treatment. Methods This study used a qualitative design based on twenty in-depth interviews of patients with cancer or caregivers of patients with the disease. The analysis of the text was based on an inductive thematic approach. Results Resistance to disease and immune enhancement are properties attributed to Coragyps atratus when used for cancer treatment. The most recommended method of use is fresh blood ingestion, and the associated mechanism of action is transfer of immune factors to the individual who consumes it. Conclusions Use of Coragyps atratus as a treatment for cancer is a popular alternative therapy in Colombia. More studies are needed to understand the clinical effects of this intervention in cancer patients.

RESUMEN EJECUTIVO El impulso para desarrollar e implementar estrategias de medicina integrativa está enraizado en el deseo de mejorar la atención al paciente. The Bravewell Collaborative, una organización sin ánimo de lucro dedicada a la mejora de la atención sanitaria, define la medicina integrativa como “un enfoque de la medicina que coloca al paciente en el centro y se dirige al conjunto completo de influencias físicas, emocionales, mentales, sociales, espirituales y ambientales que afectan a la salud de la persona. Con una estrategia personalizada que considera las condiciones, necesidades y circunstancias únicas del paciente, utiliza las intervenciones más apropiadas de una variedad de disciplinas científicas para curar la afección y la enfermedad y ayudar a las personas a recobrar y mantener una salud óptima”. En las pasadas dos décadas, se ha documentado un número creciente de centros clínicos que proporcionan medicina integrativa, el número de facultades y escuelas médicas que enseñan estrategias integrativas, el número de investigadores que estudian intervenciones integrativas, y el número de pacientes que solicitan cuidados integrativos. Pero se desconocía si la medicina integrativa se estaba ofreciendo de manera igual, similar, o dispar. Además, mientras que los estudios anteriores se centraban en la prevalencia y el uso de la medicina complementaria o alternativa (MCA) por parte de los pacientes1,2 o de los médicos en hospitales3, enumerando la utilización de terapias MCA individuales, se había recogido muy poca información con respecto a la práctica real de la medicina integrativa que, por definición, trata a la persona en su conjunto. En 2011, The Bravewell Collaborative encargó una encuesta para determinar la forma en que la medicina integrativa se estaba practicando en los Estados Unidos: (1) describiendo las poblaciones de pacientes y las afecciones sanitarias tratadas más habitualmente; (2) definiendo las pr

Los datos del estudio PREDYCES® nos revelaron que en España la desnutrición relacionada con la enfermedad (DRE) afecta a uno de cada cuatro pacientes hospitalizados. Esta cifra aumenta hasta el 36,8% en los pacientes hematológicos. Se calcula que un 20% de los pacientes oncológicos muere por complicaciones relacionadas con la DRE. Nuestro grupo se planteó en 2011 comenzar la implantación de un cribado nutricional en los servicios con mayor riesgo de DRE. La presente revisión trata de describir todo el proceso que hemos seguido para mejorar la situación nutricional en los pacientes ingresados en el Servicio de Hematología del Complejo Asistencial Universitario de León (CAULE), mayoritariamente con diagnóstico de neoplasias hematológicas. En un primer estudio piloto, detectamos una alta prevalencia de desnutrición, que tendió a aumentar durante la hospitalización. Además, solo el 8,3% los enfermos valorados recibieron algún tipo de soporte nutricional y no se estaban cubriendo sus necesidades ni calóricas ni proteicas, lo que se asociaba a un peor pronóstico. Por este motivo, nos decidimos a implantar de manera sistemática un cribado y una intervención nutricional adecuada, que comenzó en 2011 y que ha recibido el reconocimiento como Buena Práctica del Sistema Nacional de Salud.

complicated endoscopic solutions. Bypass gástrico em Y-de-Roux (BGYR) é procedimento padrão em cirurgia bariátrica. Gastrectomia vertical e banda gástrica, embora com bons resultados na literatura, estão mostrando taxas mais elevadas de insucesso no tratamento para reduzir a morbidade associada à obesidade e peso corporal. Outros problemas pós-operatórios podem ocorrer, como a erosão da banda, e doença do refluxo gastroesofágico refratária à medicação. Portanto, conversão laparoscópica para BGYR pode ser alternativa eficaz, desde que indicações específicas para a revisão sejam cumpridas. Analisar os nossos dados e os da literatura sobre procedimentos bariátricos revisionais para avaliar melhores alternativas para a prática atual. Foram efetuados experiência institucional e revisão sistemática da literatura sobre cirurgia bariátrica revisional. Procedimentos endoscópicos estão sendo aplicados recentemente para melhorar a falha e complicações de procedimentos bariátricos. Falha terapêutica após BGYR ocorre em até 20%. A redução transoral é atualmente um método alternativo para reduzir a anastomose gastrojejunal. A gastrectomia vertical pode apresentar aumento de volume e do diâmetro do pouch , o qual podem ser reduzidos por meio de sutura total endoscópica longitudinal. Síndrome de dumping e episódios de hipoglicemia grave (neuroglicopenia) podem estar presentes nos pacientes com BGYR. Os episódios hipoglicêmicos devem ser avaliados e geralmente podem ser tratados convencionalmente. Para evitar pancreatectomia parcial ou conversão à anatomia normal, uma nova abordagem laparoscópica com ressecção do remanescente gástrico e interposição de jejuno, pode ser aplicada como alternativa em não-respondedores. Episódios de hipoglicemia melhoram, enquanto a perda de peso é mantida. Procedimentos revisionais endoscópicos podem ser aplicados após cirurgia bariátrica em pacientes com sintomas colaterais ou na falha do tratamento

Obesity is an epidemic and chronic disease that can bring other comorbidities to the patient. Non-alcoholic fatty liver disease is present in up to 90% of these patients and can progress to hepatitis and hepatocarcinoma. The relationship of this liver disease and obesity is already well known; however, it is possible that some parameters of the comorbidities are more related than others in the pathophysiology of the disease. Was analyzed the relationship between non-alcoholic fatty liver disease (NAFLD) and the comorbidities of metabolic syndrome in morbidly obese patients. Was involved ultrasonography and laboratory assessment of obese patients before bariatric surgery. NAFLD was assessed using the same sonography parameters for all patients. Based on the results, the patients were divided into groups with and without NAFLD. Comparisons between them involved clinical and laboratory variables such as fasting blood glucose, insulin, HOMA-IR (homeostasis model assessment - insulin resistance), glycated hemoglobin, total cholesterol and fractions, triglycerides, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, C-reactive protein, albumin and ferritin. Patients who reported alcohol abuse (defined as the consumption of >14 drinks per week) or who had hepatitis were excluded. Eighty-two patients (74 women and 8 men) were studied, of whom 53 (64.6%) had NAFLD and 29 (35.4%) did not. The levels of glycated hemoglobin (p=0.05) and LDL cholesterol (p=0.01) were significantly altered in patients with NAFLD. However, weight, body mass index and excess weight did not differ significantly between the groups (p=0.835, p=0.488 and p=0.727, respectively). Altered LDL cholesterol and glycated hemoglobin levels were related to the presence of NAFLD. A obesidade é doença epidêmica e crônica que pode trazer outras comorbidades ao paciente. A doença hepática gordurosa não alcoólica está presente em até 90% desses pacientes e pode evoluir para

Official blame for drivers with very low blood alcohol content: there is no safe combination of drinking and driving.

Some laboratory studies find that driving is impaired even at blood alcohol content (BAC)=0.01%. However, no real-world traffic studies have investigated whether minimally 'buzzed' drivers (BAC=0.01%) are more likely to be blamed for a crash than are the sober drivers they collide with. To determine whether official blame for a crash increases significantly at BAC=0.01%. We examined the relationship between the driver's BAC and the degree to which he or she was assigned sole official blame (SOB) for the crash. We analysed an official, exhaustive, nationwide US database (Fatality Analysis Reporting System; n=570 731), covering 1994-2011. Even minimally 'buzzed' drivers are 46% (24-72%) more likely to be officially blamed for a crash than are the sober drivers they collide with (χ(2)=20.45; p=0.000006). There is no threshold effect-no sudden transition from blameless to blamed drivers at BAC=0.08% (the US legal limit). Instead, SOB increases smoothly and strongly with BAC (r=0.98 (0.96-0.99) for male drivers, p<0.000001; r=0.99 (0.97-0.99) for female drivers, p<0.000001). This near-linear SOB-to-BAC relationship begins at BAC=0.01% and ends around BAC=0.24%. Our findings persist after controlling for many confounding variables. There appears to be no safe combination of drinking and driving-even minimally 'buzzed' drivers pose increased risk to themselves and to others. Concerns about drunk driving should also be extended to 'buzzed' driving. US legislators should reduce the legal BAC limit, perhaps to 0.05%, as in most European countries. Lowering the legal BAC limit is likely to reduce injuries and save lives. Published by the BMJ Publishing Group Limited.

Introducción:la nutrición parenteral (NP) a largo plazo puede asociarse a complicaciones graves, con un deterioro importante de la calidad de vida de los pacientes con síndrome de intestino corto (SIC). Teduglutida, un análogo del péptido-2 similar al glucagón, pertenece a una nueva familia terapéutica y representa el primer abordaje no sintomático del SIC. Objetivos: revisar los datos preclínicos y clínicos en cuanto a eficacia y seguridad de teduglutida. Resultados: la aprobación de teduglutida se basó en los resultados de un estudio en fase III de 24 semanas, doble ciego, controlado con placebo (STEPS). Pacientes con fallo intestinal por SIC dependientes de NP ≥ 3 veces/semana durante ≥ 12 meses recibieron 0,05 mg/kg de teduglutida (n = 43) o placebo (n = 43) 1 vez/día. En la semana 24 hubo significativamente más respondedores en el grupo de teduglutida que en el de placebo (63 vs.30%; p = 0,002). La reducción absoluta media del volumen de NP frente al valor basal en la semana 24 fue significativamente mayor con teduglutida (4,4 vs.2,3 l/semana; p < 0,001). La necesidad de NP se redujo ≥ 1 día en la semana 24 en el 54% de pacientes tratados con teduglutida vs.23% con placebo. Del total de pacientes que recibieron teduglutida en los ensayos en fase III (n = 134), el 12% consiguió una autonomía completa de la NP. Por lo general, la administración subcutánea de teduglutida se toleró bien. Conclusiones: se ha demostrado que teduglutida recupera la absorción intestinal y reduce significativamente la dependencia de la NP, consiguiendo incluso la independencia en algunos pacientes.

INTRODUCCIONEl derrame pleural neoplásico (DPN) implica una enfermedad oncológica avanzada. La biopsia pleural por cirugía torácica endoscópica permite el diagnóstico en más del 90% de los casos y la instrumentación del espacio pleural complicado, mejorando los resultados de la técnica.MATERIAL Y METODOSe realizó un análisis retrospectivo de pacientes con DPN operados para la realización de una pleurodesis química con talco. Se formaron dos grupos, uno con derrame pleural neoplásico complicado (DPNC) y otro con derrame pleural neoplásico no complicado (DPNNC). En el grupo con DPNC se realizó "maniobras de liberación - expansión". Se compararon las variables entre ambos grupos para el análisis pertinente.RESULTADOSSe analizaron 28 pacientes con DPN tratados con pleurodesis química por cirugía torácica endoscópica. La edad promedio fue de 62,64 años. El compromiso pleural por patología mamaria fue la forma más frecuente (46,4%). No se hubo diferencia en cuanto a complicaciones (p= 0,31) y riesgo de defunción a los 30 días (p=1,09) con el manejo agresivo del espacio pleural. La demora en la indicación de pleurodesis se relacionó con un mayor índice de complicaciones (p=0,002) y mayor probabilidad de defunción dentro de los 30 días (p=0,008). La mayoría de pacientes se reinsertó a sus tareas diarias, con buena tolerancia a la disnea luego del procedimiento.  CONCLUSIONEn los pacientes con DPNC, las "maniobras de liberación - expansión pulmonar" descriptas, aumentarían las chances de mejorar los resultados con bajo riesgo. La pleurodesis química temprana mejora la calidad de vida de los pacientes portadores de un DPN.

The SAMe-TT2R2 score was developed to predict which patients on oral anticoagulation with vitamin K antagonists (VKAs) will reach an adequate time in therapeutic range (TTR) (> 65%-70%). Studies have reported a relationship between this score and the occurrence of adverse events. To describe the TTR according to the score, in addition to relating the score obtained with the occurrence of adverse events in patients with nonvalvular atrial fibrillation (AF) on oral anticoagulation with VKAs. Retrospective cohort study including patients with nonvalvular AF attending an outpatient anticoagulation clinic of a tertiary hospital. Visits to the outpatient clinic and emergency, as well as hospital admissions to the institution, during 2014 were evaluated. The TTR was calculated through the Rosendaal´s method. We analyzed 263 patients (median TTR, 62.5%). The low-risk group (score 0-1) had a better median TTR as compared with the high-risk group (score ≥ 2): 69.2% vs. 56.3%, p = 0.002. Similarly, the percentage of patients with TTR ≥ 60%, 65% or 70% was higher in the low-risk group (p < 0.001, p = 0.001 and p = 0.003, respectively). The high-risk group had a higher percentage of adverse events (11.2% vs. 7.2%), although not significant (p = 0.369). The SAMe-TT2R2 score proved to be effective to predict patients with a better TTR, but was not associated with adverse events.

We used tools to characterize the subjects and the Folkman and Lazarus Inventory of Coping Strategies. the coping strategies most often used by family members were social support and problem solving. Mothers and fathers used more functional strategies (self-control p=0.037, positive reappraisal p=0.037, and social support p=0,021). We found no significant differences between the strategies and other variables examined. despite the suffering resulting from the illness of a dear one, family members make more use of functional strategies, allowing them to cope with adversities in a more well-adjusted way. identificar as estratégias de enfrentamento de familiares de pacientes com transtornos mentais e relacioná-las com as variáveis sociodemográficas do familiar e clínicas do paciente. estudo descritivo, desenvolvido em hospital psiquiátrico do interior do estado de São Paulo, com 40 familiares de pacientes internados, maiores de 18 anos e que acompanhavam o paciente antes e durante a internação.

to evaluate the effectiveness of Roux-en-Y gastric bypass in improving the glycemic profile of obese patients with type 2 Diabetes Mellitus (DM2) after 18 months of follow-up. four hundred sixty-eight pacients with DM2 and BMI ≥35 were submitted to Roux-en-Y gastric bypass, from 1998 to 2010. All patients were submitted to glycemic control analysis in the 3rd, 6th, 9th, 12th and 18th postoperative months. We considered: type 2 diabetic patients, the ones with fasting glucose ≥126mg/dl and HbA1C ≥6.5 in two dosages; high risk patients for diabetes, those who presented fasting glucose ≥ 100 to 125 mg/dl and HbA1C between 5.7%-6.4%; and normal patients, those presenting glucose <100mg/dl and HbA1C <5.7%. Such diagnostic criteria were based on the official position of Sociedade Brasileira de Diabetes, published in July, 2011. The remission of DM2 was seen in 410 (87.6%) out of 468 patients 18 months after the surgery, that being a meaningful difference, with p<0.001. Fourty-eight (10.3%) patients sustained criteria for the disease and ten (2.1%) continued at high risk for DM2. Roux-en-Y gastric bypass was effective in the promotion and maintaince of long-term glycemic control. There are evidences showing that the remission of DM2 is not only related to weight loss and that other enteroinsular axis mechanisms must be involved. avaliar a eficácia da gastroplastia com derivação em Y-de-Roux, em pacientes obesos e portadores de Diabetes Mellitus tipo 2 (DM2), na melhoria do perfil glicêmico após 18 meses de seguimento. foram submetidos à derivação gástrica em Y-de-Roux 468 pacientes com IMC ≥35 e portadores de DM2, no período de 1998 a 2010.

This was a retrospective descriptive study of all adult patients (≥ 18 years of age) diagnosed with SPM between January of 2004 and September of 2015. At least one predisposing factor was identified in most (88.9%) of the 18 patients who presented with SPM during the study period. With regard to precipitating factors, bouts of cough were present in 50.0% of the patients. Other precipitating factors included a sudden increase in tobacco consumption, inhaled drug use, occupational inhalation of varnish fumes, intense exercise, and vomiting. The most common complaints were dyspnea (in 83.3%) and chest pain (in 77.8%). Other complaints included cough, neck pain, dysphagia, and odynophagia. Subcutaneous emphysema was found in most of the patients. The diagnosis of SPM was based on chest X-ray findings in 61.1% of the patients. Although SPM is a rare condition, it should be considered in the differential diagnosis of chest pain and dyspnea. It can develop without a triggering event or conclusive findings on a chest X-ray, which is usually sufficient for diagnosis.

A quantitative cross-sectional study that used the Self Assessment Questionnaire 30 translated into Portuguese. The data were processed by analysis of variance (ANOVA) in addition to descriptive statistics, with statistical significance set at p-value ≤ 0.05. According to the participants' perceptions, the significant dimensions of patient safety culture were 'patient safety climate' and 'organizational learning', with 81% explanatory power. Mean scores showed that among private organizations, higher values were attributed to statements; however, the correlation between dimensions was stronger among government hospitals. Different hospital organizations present distinct values for each dimension of patient safety culture and their investigation enables professionals to identify which dimensions need to be introduced or improved to increase patient safety.

Scientific advances and the complexity of human knowledge generate a constant need for creating new tools intended to facilitate learning in an agreeable and lasting form. Simulated patients are one of such tools in medical education. Standardized or simulated patients are actors or people vigorously trained to represent a medical history or, if possible, specific physical findings with the purpose of using such representations as an educational and evaluating supplement in clinic practice. The use of simulated patients has been very well received, particularly in the psychiatric field; however, its usefulness in areas such as psychotherapy or evaluation of residents remains questionable. A search was made in PubMed with the MESH words ("Psychiatry/education" and "Patient Simulation"); a search was also made in LILACS and scholar Google using similar words. Simulated patients are widely used throughout the world in the psychiatry field and their usefulness as an academic tool for pre-graduate students is confirmed in most of the literature reviewed. One of the main benefits of the use of this kind of patients is the acquisition of specific abilities (e.g.: medical history recording); nevertheless, its efficacy in more complex experiences like psychotherapy or certification of psychiatry residents is questioned. Notwithstanding the controversy, most of the literature reviewed confirms the benefits and acceptance of this methodology in the formation of students and psychiatrists.

Working memory still needs verbal rehearsal.

The causal role of verbal rehearsal in working memory has recently been called into question. For example, the SOB-CS (Serial Order in a Box-Complex Span) model assumes that there is no maintenance process for the strengthening of items in working memory, but instead a process of removal of distractors that are involuntarily encoded and create interference with memory items. In the present study, we tested the idea that verbal working memory performance can be accounted for without assuming a causal role of the verbal rehearsal process. We demonstrate in two experiments using a complex span task and a Brown-Peterson paradigm that increasing the number of repetitions of the same distractor (the syllable ba that was read aloud at each of its occurrences on screen) has a detrimental effect on the concurrent maintenance of consonants whereas the maintenance of spatial locations remains unaffected. A detailed analysis of the tasks demonstrates that accounting for this effect within the SOB-CS model requires a series of unwarranted assumptions leading to undesirable further predictions contradicted by available experimental evidence. We argue that the hypothesis of a maintenance mechanism based on verbal rehearsal that is impeded by concurrent articulation still provides the simplest and most compelling account of our results.

To evaluate the effectiveness of procalcitonin (PCT)-guided antibiotic treatment compared to current treatment practice to reduce 90-day all-cause mortality in emergency patients with shortness of breath (SOB) and suspected acute heart failure (AHF). Concomitant AHF and lower respiratory tract (or other bacterial) infection in emergency patients with dyspnea are common and can be difficult to diagnose. Early and adequate initiation of antibiotic therapy (ABX) significantly improves patient outcome, but superfluous prescription of ABX maybe harmful. In a multicentre, prospective, randomized, controlled process trial with an open intervention, adult emergency patients with SOB and increased levels of natriuretic peptides will be randomized to either a standard care group or a PCT-guided group with respect to the initiation of antibiotic treatment. In the PCT-guided group, the initiation of antibiotic therapy is based on the results of acute PCT measurements at admission, using a cut-off of 0.2 ng/ml. A two-stage sample-size adaptive design is used; an interim analysis was done after completion of 50% of patients and the final sample size remained unchanged. Primary endpoint is 90-day all-cause mortality. The current study will provide evidence, whether the routine use of PCT in patients with suspected AHF improves outcome.

Glass sponge (Hexactinellida, Porifera) is a special lineage because of its unique tissue organization and skeleton material. Structure and physiology of glass sponge have been extensively studied. However, our knowledge of the glass sponge-associated microbial community and of the interaction with the host is rather limited. Here, we performed genomic studies on the microbial community in the glass sponge Lophophysema eversa in seamount. The microbial community was dominated by an ammonia-oxidizing archaeum (AOA), a nitrite-oxidizing bacterium (NOB) and a sulfur-oxidizing bacterium (SOB), all of which were autotrophs. Genomic analysis on the AOA, NOB and SOB in the sponge revealed specific functional features of sponge-associated microorganisms in comparison with the closely related free-living relatives, including chemotaxis, phage defence, vitamin biosynthesis and nutrient uptake among others, which are related to ecological functions. The three autotrophs play essential roles in the cycles of carbon, nitrogen and sulfur in the microenvironment inside the sponge body, and they are considered to play symbiotic roles in the host as scavengers of toxic ammonia, nitrite and sulfide. Our study extends knowledge regarding the metabolism and the evolution of chemolithotrophs inside the invertebrate body. © 2015 Society for Applied Microbiology and John Wiley & Sons Ltd.

To measure the role of enterovirus detection in cerebrospinal fluid compared with the Bacterial Meningitis Score in children with meningitis. A retrospective cohort based on analysis of medical records of pediatric patients diagnosed as meningitis, seen at a private and tertiary hospital in São Paulo, Brazil, between 2011 and 2014. Excluded were patients with critical illness, purpura, ventricular shunt or recent neurosurgery, immunosuppression, concomitant bacterial infection requiring parenteral antibiotic therapy, and those who received antibiotics 72 hours before lumbar puncture. The study included 503 patients. Sixty-four patients were excluded and 94 were not submitted to all tests for analysis. Of the remaining 345 patients, 7 were in the Bacterial Meningitis Group and 338 in the Aseptic Meningitis Group. There was no statistical difference between the groups. In the Bacterial Meningitis Score analysis, of the 338 patients with possible aseptic meningitis (negative cultures), 121 of them had one or more points in the Bacterial Meningitis Score, with sensitivity of 100%, specificity of 64.2%, and negative predictive value of 100%. Of the 121 patients with positive Bacterial Meningitis Score, 71% (86 patients) had a positive enterovirus detection in cerebrospinal fluid. Enterovirus detection in cerebrospinal fluid was effective to differentiate bacterial from viral meningitis. When the test was analyzed together with the Bacterial Meningitis Score, specificity was higher when compared to Bacterial Meningitis Score alone.

To determine the prevalence of alpha 1-antitrypsin (AAT) deficiency (AATD), as well as allele frequency, in COPD patients in Brazil. This was a cross-sectional study involving 926 COPD patients 40 years of age or older, from five Brazilian states. All patients underwent determination of AAT levels in dried blood spot (DBS) samples by nephelometry. Those with DBS AAT levels ≤ 2.64 mg/dL underwent determination of serum AAT levels. Those with serum AAT levels of < 113 mg/dL underwent genotyping. In case of conflicting results, SERPINA1 gene sequencing was performed. Of the 926 COPD patients studied, 85 had DBS AAT levels ≤ 2.64 mg/dL, and 24 (2.6% of the study sample) had serum AAT levels of < 113 mg/dL. Genotype distribution in this subset of 24 patients was as follows: PI*MS, in 3 (12.5%); PI*MZ, in 13 (54.2%); PI*SZ, in 1 (4.2%); PI*SS, in 1 (4.2%); and PI*ZZ, in 6 (25.0%). In the sample as a whole, the overall prevalence of AATD was 2.8% and the prevalence of the PI*ZZ genotype (severe AATD) was 0.8. The prevalence of AATD in COPD patients in Brazil is similar to that found in most countries and reinforces the recommendation that AAT levels be measured in all COPD patients.

To verify the effects of antihypertensive treatment (pharmacological and non-pharmacological) on the health-related quality of life of individuals with hypertension. We conducted a systematic review with meta-analysis using the following databases: IBECS, LILACS, SciELO, Medline, Cochrane, Science Direct, Scopus and the Brazilian Capes Theses and Dissertations Database. The statistical analysis was performed using Review Manager, version 5.2. The average difference was used for the summarization of meta-analytic effect by the fixed-effect model. Twenty studies were included. The summarization of the effect showed an average increase of 2.45 points (95%CI 1.02-3.87; p < 0.0008) in the quality of life of individuals adhering to non-pharmacological treatment for arterial hypertension. Adherence to pharmacological treatment indicated an average increase of 9.24 points (95%CI 8.16-10.33; p < 0.00001) in the quality of life of individuals with arterial hypertension. Non-pharmacological treatment improves the overall quality of life and physical domain of people with arterial hypertension. Adherence to pharmacological treatment has a positive impact on the mental and physical domains of patients, as it did on the overall quality of life score.

To evaluate the properties of the Identity-Consequence Fatigue Scale (ICFS) in patients with lung cancer (LC), assessing the intensity of fatigue and associated factors. This was a cross-sectional study involving LC patients, treated at a teaching hospital in Brazil, who completed the ICFS. Patients with chronic heart disease (CHD) and healthy controls, matched for age and gender, also completed the scale. Initially, a Brazilian Portuguese-language version of the ICFS was administered to 50 LC patients by two independent interviewers; to test for reproducibility, it was readministered to those same patients. At baseline, the LC patients were submitted to spirometry and the six-minute walk test, as well as completing the Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale (HADS), Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), and Fatigue Severity Scale (FSS). Inflammatory status was assessed by blood C-reactive protein (CRP) levels. To validate the ICFS, we assessed the correlations of its scores with those variables. The sample comprised 50 patients in each group (LC, CHD, and control). In the LC group, the intraclass correlation coefficients for intra-rater and inter-rater reliability regarding ICFS summary variables ranged from 0.94 to 0.76 and from 0.94 to 0.79, respectively. The ICFS presented excellent internal consistency, and Bland-Altman plots showed good test-retest reliability. The ICFS correlated significantly with FSS, HADS, and SF-36 scores, as well as with CRP levels. Mean ICFS scores in the LC group differed significantly from those in the CHD and control groups. The ICFS is a valid, reliable instrument for evaluating LC patients, in whom depression, quality of life, and CRP levels seem to be significantly associated with fatigue.

The accuracy of zero coronary calcium score as a filter in patients with chest pain has been demonstrated at the emergency room and outpatient clinics, populations with low prevalence of coronary artery disease (CAD). To test the gatekeeping role of zero calcium score in patients with chest pain admitted to the coronary care unit (CCU), where the pretest probability of CAD is higher than that of other populations. Patients underwent computed tomography for calcium scoring, and obstructive CAD was defined by a minimum 70% stenosis on invasive angiography. In 146 patients studied, the prevalence of CAD was 41%. A zero calcium score was present in 35% of the patients. The sensitivity and specificity of zero calcium score yielded a negative likelihood ratio of 0.16. After logistic regression adjustment for pretest probability, zero calcium score was independently associated with lower odds of CAD (OR = 0.12, 95%CI = 0.04-0.36), increasing the area under the ROC curve of the clinical model from 0.76 to 0.82 (p = 0.006). Zero calcium score provided a net reclassification improvement of 0.20 (p = 0.0018) over the clinical model when using a pretest probability threshold of 10% for discharging without further testing. In patients with pretest probability < 50%, zero calcium score had a negative predictive value of 95% (95%CI = 83%-99%), with a number needed to test of 2.1 for obtaining one additional discharge. Zero calcium score substantially reduces the pretest probability of obstructive CAD in patients admitted to the CCU with acute chest pain. (Arq Bras Cardiol. 2017; [online].ahead print, PP.0-0).

Introducción: la Aspergilosis Invasiva (AI) del Sistema Nervioso Central (SNC) es infrecuente y ocurre generalmente en pacientes inmunocomprometidos. Puede presentarse con cuadros de meningitis, aneurismas micóticos, infartos o abscesos. Es una infección con pronóstico reservado y puede afectar el SNC de forma primaria o secundaria a partir de un foco que se disemina por vía hematógena. Presentamos el caso de un paciente con AI con invasión primaria a nivel óseo y diseminación posterior al cerebro. Caso clínico: Paciente masculino de 25 años con diagnóstico de leucemia linfática aguda en tratamiento quimioterápico que presentó neumonitis por metotrexate por lo que inicia tratamiento con corticoides. Posteriormente agregó cervicalgia y con el diagnóstico de osteomielitis cervical se realiza punción bajo tomografía computada (TC) sin aislarse gérmenes. Se colocó Halo Vest e inició tratamiento antibiótico empírico. Posteriormente presentó afasia de expresión secundaria a lesión frontal izquierda. Se realizó evacuación de absceso cerebral aislando A. fumigatus. El tratamiento antibiótico específico posterior permitió una buena respuesta clínica y radiológica. Conclusión: La presencia de lesiones en el SNC de pacientes inmunocomprometidos debe incluir a las micosis como diagnóstico diferencial. La evacuación quirúrgica permite llegar rápidamente al diagnóstico mejorando la respuesta posterior al tratamiento antibiótico. Para evaluar la respuesta terapéutica y posibles recaídas se debe realizar un seguimiento periódico clínico radiológico.

Las mismas fueron realizadas en el Hospital Italiano de Buenos Aires durante el período junio del 2011 a junio del 2012. Se analizaron las características demográficas de los pacientes, la patología de base y la morbimortalidad asociada a la cirugía. Resultados: La edad media de los pacientes fue de 41,52 años con un rango de 18-79. La distribución fue similar entre hombres y mujeres. Las patologías más frecuentes fueron: adenomas no funcionantes (40.4%), tumores productores de GH/Acromegalia (25%) y tumores productores de ACTH/Enfermedad de Cushing (23.1%). Aproximadamente el 70 % correspondieron a macroadenomas. Sólo un paciente presentó complicaciones. No se registro ningún óbito. Conclusión: Si bien podremos objetivar fehacientemente resultados más concluyentes en futuros trabajos, podemos decir a priori que, en la endoscopía el detalle anatómico es claramente superior al microscópico y que la posibilidad de la introducción del endoscopio en la silla turca permite la visualización directa de remanentes tumorales, de sitios de fístula y como así también de la glándula normal, ventajas que potencialmente podrían permitir obtener mejores resultados quirúrgicos, en términos de control de la enfermedad y tasa de complicaciones.

Reuse of organobentonites with a carbon dioxide responsive solvent.

PubMed

Luan, Ling-Yu; Zhang, Li; Wang, Li-Hong

2018-05-22

Synthesized organobentonite (SOB), montmorillonite (MMT), and commercial organobentonite (COB) were used as adsorbents for paraffin oil, a model pollutant in land-based oil spills and oil pipeline rupture. The characterization of clays was carried out with scanning electron microscopy (SEM), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). After adsorption, oil was separated from adsorbents with a carbon dioxide responsive solvent N,N-dimethylcyclohexylamine (DMCHA), and DMCHA was subsequently separated from paraffin oil upon CO 2 bubbling instead of distillation with high energy cost. The adsorption capacity of oil to SOB, MMT, and COB was 0.686, 1.124, and 1.239 g/g, respectively. It was found that the adsorption capacity and rinsed amount of the adsorbents depended on the d-spacing, which is related to surfactant content. Electrical conductivity and pH measurements suggested that the separation process occurred via two steps. Firstly, during the initial 35 min, carbonate ions coexisted with bicarbonate ions. Then, only bicarbonate ions existed after the introduction of CO 2 gas for 120 min. Thus, organobentonites were feasible for hydrocarbon adsorption and could be simply reused by an amine-based responsive solvent. This work provided a cost-effective and sustainable method of recycling of organobentonites and the responsive solvent, which can be used to deal with leaked oil and oil spills.

Control of information in working memory: Encoding and removal of distractors in the complex-span paradigm.

PubMed

Oberauer, Klaus; Lewandowsky, Stephan

2016-11-01

The article reports four experiments with complex-span tasks in which encoding of memory items alternates with processing of distractors. The experiments test two assumptions of a computational model of complex span, SOB-CS: (1) distractor processing impairs memory because distractors are encoded into working memory, thereby interfering with memoranda; and (2) free time following distractors is used to remove them from working memory by unbinding their representations from list context. Experiment 1 shows that distractors are erroneously chosen for recall more often than not-presented stimuli, demonstrating that distractors are encoded into memory. Distractor intrusions declined with longer free time, as predicted by distractor removal. Experiment 2 shows these effects even when distractors precede the memory list, ruling out an account based on selective rehearsal of memoranda during free time. Experiments 3 and 4 test the notion that distractors decay over time. Both experiments show that, contrary to the notion of distractor decay, the chance of a distractor intruding at test does not decline with increasing time since encoding of that distractor. Experiment 4 provides additional evidence against the prediction from distractor decay that distractor intrusions decline over an unfilled retention interval. Taken together, the results support SOB-CS and rule out alternative explanations. Data and simulation code are available on Open Science Framework: osf.io/3ewh7. Copyright © 2016 Elsevier B.V.

A mathematical model of carbon, nitrogen and sulfur removal (C-N-S) from industrial wastewater was constructed considering the interactions of sulfate-reducing bacteria (SRB), sulfide-oxidizing bacteria (SOB), nitrate-reducing bacteria (NRB), facultative bacteria (FB), and methane producing archaea (MPA). For the kinetic network, the bioconversion of C-N by heterotrophic denitrifiers (NO 3 - →NO 2 - →N 2 ), and that of C-S by SRB (SO 4 2- →S 2- ) and SOB (S 2- →S 0 ) was proposed and calibrated based on batch experimental data. The model closely predicted the profiles of nitrate, nitrite, sulfate, sulfide, lactate, acetate, methane and oxygen under both anaerobic and micro-aerobic conditions. The best-fit kinetic parameters had small 95% confidence regions with mean values approximately at the center. The model was further validated using independent data sets generated under different operating conditions. This work was the first successful mathematical modeling of simultaneous C-N-S removal from industrial wastewater and more importantly, the proposed model was proven feasible to simulate other relevant processes, such as sulfate-reducing, sulfide-oxidizing process (SR-SO) and denitrifying sulfide removal (DSR) process. The model developed is expected to enhance our ability to predict the treatment of carbon-nitrogen-sulfur contaminated industrial wastewater. Copyright © 2016 Elsevier B.V. All rights reserved.

In this study, we created two distinct narratives by changing only a few words in each sentence (e.g., "he" to "she" or "sobbing" to "laughing") while preserving the grammatical structure across stories. We then measured changes in neural responses between the two stories. We found that differences in neural responses between the two stories gradually increased along the hierarchy of processing timescales. For areas with short integration windows, such as early auditory cortex, the differences in neural responses between the two stories were relatively small. In contrast, in areas with the longest integration windows at the top of the hierarchy, such as the precuneus, temporal parietal junction, and medial frontal cortices, there were large differences in neural responses between stories. Furthermore, this gradual increase in neural differences between the stories was highly correlated with an area's ability to integrate information over time. Amplification of neural differences did not occur when changes in words did not alter the interpretation of the story (e.g., sobbing to "crying"). Our results demonstrate how subtle differences in words are gradually accumulated and amplified along the cortical hierarchy as the brain constructs a narrative over time.

Durante la última década, el conocimiento de nuevos mecanismos implicados en el desarrollo del cáncer ha permitido el diseño de nuevos fármacos para su tratamiento y la mayor parte de ellos son fármacos que se administran por vía oral. Uno de los principales problemas de los pacientes oncohematológicos es la desnutrición, que suele tener causas multifactoriales (de la propia enfermedad, de los pacientes y de los diferentes tratamientos administrados). Para minimizar el impacto de la desnutrición es necesaria una intervención nutricional, ya sea adaptando la dieta o mediante la instauración de soporte nutricional artificial, en función de la gravedad de cada caso. En cualquier paciente que esté recibiendo un tratamiento oncológico hay que evaluar las posibles interacciones que pueden existir con el soporte nutricional instaurado, ya sea dieta oral, suplementación oral o nutrición enteral. Estas interacciones pueden disminuir la eficacia, aumentar la toxicidad de los tratamientos o producir déficits nutricionales. Se detallan las principales interacciones que se pueden producir, las interacciones entre los tratamientos oncológicos y el soporte nutricional.

Gracias a los avances técnicos en técnicas neuroquirúrgicas, y debido a que el diagnóstico y la clasificación de las enfermedades psiquiátricas han evolucionado significativamente a lo largo de las últimas décadas, se están desarrollando tratamientos a nivel experimental para aquellos pacientes resistentes al manejo conservador.La anorexia nerviosa es una enfermedad de prevalencia creciente, con la tasa de mortalidad más elevada dentro de los trastornos psiquiátricos, y con aproximadamente un 20% de pacientes que presentan una evolución tórpida. Para estos pacientes que no responden a manejo conservador, la estimulación cerebral profunda ha surgido como una alternativa terapéutica, si bien la literatura especializada al respecto es escasa.A continuación presentamos una revisión de la fisiopatología de la anorexia nerviosa, así como de los distintos tratamientos neuroquirúrgicos realizados a lo largo de la historia. Se detalla la perspectiva de tratamiento quirúrgico actual, así como los aspectos éticos que se han de considerar en relación con el surgimiento de estas nuevas terapias.

to analyze possible negative effects of Attention Deficit Hyperactivity Disorder (ADHD) on the success of bariatric surgery. we evaluated forty patients undergoing bariatric surgery and with regular post-operative follow-up of at least one year. To all, we applied the questionnaire advocated in the fourth edition of the Diagnostic and Statistical Manual (DSM-IV) of the American Psychiatric Association for ADHD, as well as analyzed their postoperative data. fifteen (38%) patients presented a positive questionnaire for ADHD. Patients with ADHD presented higher BMI than patients without the disorder (45.8 vs. 40.9 kg/m2, p=0.017), and the difference remained in all postoperative stages. There was no statistically significant difference in surgery success (33.3% x 66.7%, p=0.505) or in BMI reduction (30.71% x 31.88%, p=0.671) one year after the procedure. ADHD patients have a higher BMI. However, the presence of ADHD does not influence the success of bariatric surgery and the reduction of BMI. analisar possíveis efeitos negativos do Transtorno do Déficit de Atenção e Hiperatividade (TDAH) no sucesso da cirurgia bariátrica. foram avaliados 40 pacientes submetidos à cirurgia bariátrica e com acompanhamento pós-operatório regular mínimo de um ano.

Introducción: la nutrición parenteral domiciliaria se ha convertido en un punto clave en el tratamiento de pacientes con fracaso intestinal crónico. A pesar de los importantes avances que se han producido en las últimas décadas, tanto en los accesos vasculares, como en las soluciones empleadas, las infecciones asociadas a catéter venoso central siguen constituyendo una de las complicaciones más importantes. Dentro de las estrategias para la prevención o el tratamiento de estas infecciones se encuentra el empleo de sellados con antisépticos, como el etanol o la taurolidina, o de antibióticos.Objetivo: el objetivo de este artículo es revisar la evidencia disponible sobre el empleo de sellados con antisépticos o antibióticos en el manejo de pacientes pediátricos con nutrición parenteral domiciliaria.Material y métodos: el uso de sellados con etanol o taurolidina para prevenir el desarrollo de infecciones asociadas a catéter central estaría indicado en pacientes con nutrición parenteral domiciliaria que hayan tenido más de una infección en el año anterior o que se consideren pacientes de riesgo. Los sellados con antibióticos están indicados en el tratamiento de bacteriemias asociadas a catéter central producidas por S. coagulasa-negativo o gramnegativos, asociados a un tratamiento sistémico, siempre que sea posible, con el fin de salvar el catéter. Se debería llevar a cabo la retirada del mismo cuando existan signos de infección del punto de entrada o del trayecto subcutáneo, o cuando el germen responsable de la infección sea S. aureus o Cándida.Conclusión: a pesar de que la fuerza de la evidencia sobre la eficacia del sellado en la prevención o el tratamiento de infecciones asociadas al catéter es limitada, tanto en el niño como en el adulto, cada vez existen más datos a usar esta alternativa en pacientes con nutrición parenteral domiciliaria en los que la atención y salvaguarda de los catéteres es primordial.

To identify the incidence of delirium, compare the demographic and clinical characteristics of patients with and without delirium, and verify factors related to delirium in critical care patients. Prospective cohort with a sample made up of patients hospitalized in the Intensive Care Unit (ICU) of a university hospital. Demographic, clinical variables and evaluation with the Confusion Assessment Method for Intensive Care Unit to identify delirium were processed to the univariate analysis and logistic regression to identify factors related to the occurrence of delirium. Of the total 149 patients in the sample, 69 (46.3%) presented delirium during ICU stay, whose mean age, severity of illness and length of ICU stay were statistically higher. The factors related to delirium were: age, midazolam, morphine and propofol. Results showed high incidence of ICU delirium associated with older age, use of sedatives and analgesics, emphasizing the need for relevant nursing care to prevent and identify early, patients presenting these characteristics.

Des patients psychotiques et Borderline ont évalué leur image d'eux-mêmes et leur perception de leur mère et père à l'aide du modèle de l'Analyse Structural du Comportement Social (SASB. Les patients Borderline avaient des imagess plus négatives d'eux-mêmes et de leurs parents, surtout de leur père, que les patients psychotiques et les sujets normaux, alors que les patients psychotiques se jugeaient à peine différemment des sujets normaux. L'image de soi était en relation avec les images des deux parents pour les patients Borderline et pour les sujets normaux, alors que pour les patients psychotiques, seulement l'image de la mère jouait un rôle pour leur image. En plus, les patients psychotiques ne différenciaient pas entre les pôles de contrôle et d'autonomie dans l'image de soi introjectée. Nous en avons conclu que les patients Borderline se caractérisent par un attachement négatif, et les patients psychotiques par une faible séparation de la mère ainsi qu'une différenciation modeste entre autonomie et contrôle.

Psychological evaluation becomes important in so far as allows us to obtain data on personal and familiar history and allow tracing of possible psychopathology. To collect data on psychological evaluations of patients in a bariatric surgery service of a public hospital in order to describe the psychological profile of patients in this service. Data were collected from 827 patients between 2001 and 2015, using data from an interview, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Binge Eating Scale (BES). The mean age of patients before surgery was 39 years+/- 10, the mean BMI was 51 kg/m²+7, and most patients (81%) were female. The average score on the BDI was 14.8+8 and women had significantly higher scores than men. On the BAI the average score was 11+8 and on the ECAP was 14+8, both with no difference between groups. Psychosocial characteristics of the patients points to the significant presence of indicators of depression, with low levels of anxiety and binge eating.

to evaluate patient satisfaction and surgical results obtained after mastopexy with breast implant inclusion. we conducted a prospective study of 20 consecutive female patients with a mean age of 39.9 years, submitted to augmentation mastopexy. We applied semi-directed psychological interviews pre and postoperatively. The answers to the evaluations were tabulated, categorized, and allowed patient satisfaction analysis. We evaluated surgical results through photographic analysis of three independent plastic surgeons, in the pre and postoperative periods, when scores were attributed to the following items: breasts shape, breasts volume, breasts symmetry, nipple-areolar complex position, and scar quality and extent. nineteen patients (95%) referred satisfaction with the surgical results attained (p<0,001). The mean sum of the scores attributed by the three surgeons to each patient varied between 4.7 and 10, with an overall mean of 7.28. The results were considered good or great for 65% of the sample and poor for 8.4%. there was a 95% satisfaction rate among patients with the results obtained through augmentation mastopexy.

Microbially induced concrete corrosion (MICC) caused by sulfuric acid attack in sewer systems has been a serious problem for a long time. A better understanding of microbial community structures of sulfate-reducing bacteria (SRB) and sulfur-oxidizing bacteria (SOB) and their in situ activities is essential for the efficient control of MICC. In this study, the microbial community structures and the in situ hydrogen sulfide production and consumption rates within biofilms and corroded materials developed on mortar specimens placed in a corroded manhole was investigated by culture-independent 16S rRNA gene-based molecular techniques and microsensors for hydrogen sulfide, oxygen, pH and the oxidation-reduction potential. The dark-gray gel-like biofilm was developed in the bottom (from the bottom to 4 cm) and the middle (4-20 cm from the bottom of the manhole) parts of the mortar specimens. White filamentous biofilms covered the gel-like biofilm in the middle part. The mortar specimens placed in the upper part (30 cm above the bottom of the manhole) were corroded. The 16S rRNA gene-cloning analysis revealed that one clone retrieved from the bottom biofilm sample was related to an SRB, 12 clones and 6 clones retrieved from the middle biofilm and the corroded material samples, respectively, were related to SOB. In situ hybridization results showed that the SRB were detected throughout the bottom biofilm and filamentous SOB cells were mainly detected in the upper oxic layer of the middle biofilm. Microsensor measurements demonstrated that hydrogen sulfide was produced in and diffused out of the bottom biofilms. In contrast, in the middle biofilm the hydrogen sulfide produced in the deeper parts of the biofilm was oxidized in the upper filamentous biofilm. pH was around 3 in the corroded materials developed in the upper part of the mortar specimens. Therefore, it can be concluded that hydrogen sulfide provided from the bottom biofilms and the sludge settling tank was

Mangrove soils are anaerobic environments rich in sulphate and organic matter. Although the sulphur cycle is one of the major actors in this ecosystem, little is known regarding the sulphur bacteria communities in mangrove soils. We investigated the abundance, composition and diversity of sulphur-oxidizing (SOB) and sulphate-reducing (SRB) bacteria in sediments from three Brazilian mangrove communities: two contaminated, one with oil (OilMgv) and one with urban waste and sludge (AntMgv), and one pristine (PrsMgv). The community structures were assessed using quantitative real-time polymerase chain reaction (qPCR), polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and clone libraries, using genes for the enzymes adenosine-5'-phosphosulphate reductase (aprA) and sulphite reductase (Dsr) (dsrB). The abundance for qPCR showed the ratio dsrB/aprA to be variable among mangroves and higher according to the gradient observed for oil contamination in the OilMgv. The PCR-DGGE patterns analysed by Nonmetric Multidimensional Scaling revealed differences among the structures of the three mangrove communities. The clone libraries showed that Betaproteobacteria, Gammaproteobacteria and Deltaproteobacteria were the most abundant groups associated with sulphur cycling in mangrove sediments. We conclude that the microbial SOB and SRB communities in mangrove soils are different in each mangrove forest and that such microbial communities could possibly be used as a proxy for contamination in mangrove forests. © 2013 John Wiley & Sons Ltd and Society for Applied Microbiology.

Introducción. El citomegalovirus es la causa más frecuente de infección en pacientes con trasplante renal. Existen dos estrategias de similar efectividad para prevenirlo: la profilaxis universal con valganciclovir durante 90 días o el tratamiento anticipado verificando la carga viral semanal y aplicándolo solo si esta es positiva.Objetivo. Determinar cuál de estas dos estrategias sería más costo-efectiva en pacientes de riesgo intermedio en Colombia.Materiales y métodos. Se diseñó un árbol de decisiones bajo la perspectiva del tercer pagador considerando únicamente los costos médicos directos en pesos colombianos (COP) del 2014 durante un periodo de un año en una población de pacientes con riesgo intermedio para citomegalovirus (donante positivo y receptor positivo, o donante negativo y receptor positivo). Las probabilidades de transición se extrajeron de los estudios clínicos y se validaron con expertos mediante el método Delphi.Los costos de los procedimientos se basaron en el manual tarifario ISS 2001, con un incremento del 33 % a partir del índice de precios al consumidor (IPC) en salud de 2014, en tanto que los de los medicamentos se extrajeron de las circulares del Ministerio de Salud y del Sistema de Información de Medicamentos (Sismed).Resultados. La profilaxis universal con valganciclovir resultó ser menos costosa y se asoció con una menor probabilidad de infección. El costo promedio del primer año de tratamiento anticipado sería de COP$ 30'961.290, mientras que el universal sería de COP$ 29'967.834, es decir, un costo 'incremental' de COP$ 993.456.Conclusiones. Para los pacientes de riesgo intermedio con trasplante renal en Colombia, la profilaxis universal es la mejor estrategia por ser menos costosa y reducir el riesgo de infección.

Resumo Contexto As amputações dos membros inferiores, sejam definidas como maiores ou menores, são um grave problema de saúde, com altos índices de morbimortalidade e de relevante impacto social. Diferentes características clínicas dos pacientes parecem estar relacionadas aos diferentes tipos de amputação realizados. Objetivos Analisar os fatores de risco presentes em pacientes submetidos a amputações de membros inferiores em hospital terciário. Métodos Estudo retrospectivo, transversal, envolvendo 109 pacientes submetidos a amputação de membro inferior em um período de 31 meses, através da análise de gênero e idade, 15 dados clínicos e cinco parâmetros laboratoriais presentes no momento da admissão. Os dados foram submetidos a estatística descritiva e comparativa através do teste t de Student não pareado (para variáveis numéricas), e dos testes de Mann-Whitney e exato de Fisher (para variáveis categóricas). Resultados Das 109 amputações realizadas, 59 foram maiores e 50 menores. A maioria dos pacientes era do gênero masculino (65%), e a média de idade foi de 65 anos (mín. 39, máx. 93). Dentre os fatores de risco observados, idade avançada, acidente vascular encefálico, isquemia, sepse e níveis baixos de hemoglobina e hematócrito estavam estatisticamente mais relacionados às amputações maiores (p < 0,05). Diabetes melito, neuropatia e pulsos distais palpáveis foram fatores mais associados às amputações menores. Conclusões Os níveis das amputações de membros inferiores estão relacionados a diferentes fatores de risco. Os quadros isquêmicos mais graves e de maior morbidade estiveram associados a amputações maiores, enquanto a neuropatia e perfusão preservada, mais relacionados às amputações menores. PMID:29930618

Introducción: la composición lipídica de las fórmulas de nutrición parenteral (NP) se postula como posible factor de evolución clínica.Objetivo: evaluar las diferencias en eficacia y seguridad de dos emulsiones lipídicas en NP.Material y métodos: estudio clínico prospectivo de pacientes posquirúrgicos sometidos a NP durante más de 7 días en un periodo de 2 años. Se administraron de forma indistinta 2 tipos de emulsiones lipídicas: enriquecida con ácidos grasos omega 3 (SMOFlipid Fresenius Kabi®) o con ácido oleico omega 9 (Clinoleic Baxter®). Se analizaron variables epidemiológicas, analíticas, complicaciones infecciosas y mortalidad.Resultados: se estudió un total de 154 pacientes con edad media de 64,36 ± 13,73 años, de los que 95 eran hombres (61%), 78 (51%) recibieron SMOFlipid® y 76 (49%) Clinoleic®. La estancia media fue de 16,91 ± 4,23 días, la duración de la NP 9,68 ± 3,25 días y la mortalidad del 11%. Se diagnosticaron 58 (37%) infecciones. No existieron diferencias significativas en cuanto a los parámetros analíticos lipídicos, hepáticos o nutricionales (medidos al inicio y al 7.º día) ni en su evolución (estancia media, complicaciones infecciosas ni mortalidad) entre los dos grupos de pacientes.Conclusión: los pacientes sometidos a NP presentan similares características evolutivas con independencia de la emulsión lipídica utilizada. La bibliografía actual apunta a un beneficio de la disminución del aporte de ácidos grasos omega 9, pero no se han encontrado diferencias significativas entre las fórmulas comparadas.

Introducción: El temblor puede ser un desorden incapacitante y el tratamiento de primera línea para estos pacientes es farmacológico. Sin embargo, este tratamiento puede llevar a una reducción satisfactoria del temblor en sólo el 50% de los pacientes con temblor esencial. La talamotomía era el tratamiento de elección para el temblor refractario al tratamiento médico hasta que comenzó a utilizarse la estimulación cerebral profunda (ECP) del núcleo ventral intermedio (Vim) del tálamo. En la actualidad, raramente se realiza la talamotomía. Métodos: Este artículo es una revisión no sistemática de las indicaciones, resultados, parámetros de programación y técnica quirúrgica de la ECP del Vim para el tratamiento del temblor. Resultados: Aunque los resultados clínicos son similares usando la talamotomía o la ECP del Vim, la primera causa más efectos adversos que la última. Además, la ECP puede ser usada bilateralmente, mientras que la talamotomía tiene un alto riesgo de causar disartria cuando se realiza de ambos lados. La ECP del Vim logró una adecuada mejoría del temblor en varias series de pacientes con temblor causado por temblor esencial, enfermedad de Parkinson o esclerosis múltiple. Además del Vim, hay otros blancos que están siendo usados por varios autores, tales como la zona incerta y las radiaciones prelemniscales. Conclusión: La ECP del Vim es un tratamiento útil para el temblor incapacitante refractario al tratamiento médico. Es esencial realizar una precisa selección de pacientes, así como utilizar una técnica quirúrgica correcta. Aún se desconoce el mejor blanco estereotáctico para el temblor, aunque el Vim es el más usado. PMID:25165613

Identifying factors associated with glycemic control in people with type 2 Diabetes Mellitus (DM) registered in the Family Health Strategy (FHS) in Pernambuco, Brazil. Associations between glycemic control (glycosylated hemoglobin A lower or equal to 7%) presented by people with DM and variables related to sociodemographic conditions, lifestyle, characteristics of diabetes, treatment and follow-up of patients by health services were investigated by multiple regression. More than 65% of the participants presented inadequate glycemic control, especially those with lower age, longer illness duration, more annual contacts with FHS and complex therapeutic regimen. People with DM without referrals to specialists presented greater glycemic control. Associations with education level and obesity did not remain significant in the multivariate model. The evolution of diabetes hinders adequate control, however, attention to younger people with DM and referrals to specialists are factors that can improve glycemic control. Identificar fatores associados ao controle glicêmico em pessoas com Diabetes Mellitus (DM) tipo 2 cadastradas na Estratégia Saúde da Família (ESF) em Pernambuco, Brasil. Foram investigadas, por regressão múltipla, as associações entre o controle glicêmico (hemoglobina A glicosilada menor ou maior ou igual a 7%) apresentado pelas pessoas com DM e variáveis relacionadas com condições sociodemográficas, hábitos de vida, características do diabetes, de seu tratamento e acompanhamento dos pacientes pelos serviços de saúde. Mais de 65% dos participantes apresentaram controle glicêmico inadequado, principalmente aqueles com idade menor, duração da doença mais longa, mais contatos anuais com a ESF e regime terapêutico complexo. Pessoas com DM sem encaminhamentos para especialistas apresentaram um maior descontrole glicêmico. Associações com escolaridade e obesidade não permaneceram significativas no modelo multivariado.

Perioperative monitoring of coagulation is vital to assess bleeding risks, diagnose deficiencies associated with hemorrhage, and guide hemostatic therapy in major surgical procedures, such as liver transplantation. Routine static tests demand long turnaround time and do not assess platelet function; they are determined on plasma at a standard temperature of 37°C; hence these tests are ill-suited for intraoperative use. In contrast, methods which evaluate the viscoelastic properties of whole blood, such as thromboelastogram and rotational thromboelastometry, provide rapid qualitative coagulation assessment and appropriate guidance for transfusion therapy. These are promising tools for the assessment and treatment of hyper- and hypocoagulable states associated with bleeding in liver transplantation. When combined with traditional tests and objective assessment of the surgical field, this information provides ideal guidance for transfusion strategies, with potential improvement of patient outcomes. RESUMO A monitorização perioperatória da coagulação é fundamental para estimar o risco de sangramento, diagnosticar deficiências causadoras de hemorragia e guiar terapias hemostáticas durante procedimentos cirúrgicos de grande porte, como o transplante hepático. Os testes estáticos, comumente usados na prática clínica, são insatisfatórios no intraoperatório, pois demandam tempo e não avaliam a função plaquetária; são determinados no plasma e realizados em temperatura padrão de 37°C. Os métodos que avaliam as propriedades viscoelásticas do sangue total, como o tromboelastograma e a tromboelastometria rotacional, podem suprir as deficiências dos testes estáticos tradicionais, uma vez que permitem avaliar a coagulação de forma rápida e qualitativa, guiando a terapia transfusional de forma adequada. A tromboelastometria rotacional mostrou-se promissora na avaliação e no tratamento de estados de hipercoagulação e hipocoagulação, associados a

Despite successful opening of culprit coronary artery, myocardial reperfusion does not always follows primary percutaneous coronary intervention (PPCI). Glycoprotein IIb/IIIa inhibitors are used in the treatment of no-reflow (NR), but their role to prevent it is unproven. To evaluate the effect of in-lab administration of tirofiban on the incidence of NR in ST-elevation myocardial infarction (STEMI) treated with PPCI. STEMI patients treated with PPCI were randomized (24 tirofiban and 34 placebo) in this double-blinded study to assess the impact of intravenous tirofiban on the incidence of NR after PPCI according to angiographic and electrocardiographic methods. End-points of the study were: TIMI-epicardial flow grade; myocardial blush grade (MBG); resolution of ST-elevation < 70% (RST < 70%) at 90min and 24h after PPCI. Baseline anthropometric, clinical and angiographic characteristics were balanced between the groups. The occurrence of TIMI flow < 3 was not significantly different between the tirofiban (25%) and placebo (35.3%) groups. MBG ≤ 2 did not occur in the tirofiban group, and was seen in 11.7% of patients in the placebo group (p=0.13). RST < 70% occurred in 41.6% x 55.8% (p=0.42) at 90min and in 29% x 55.9% (p=0.06) at 24h in tirofiban and placebo groups, respectively. Severe NR (RST ≤ 30%) was detected in 0% x 26.5% (p=0.01) at 90 min, and in 4.2% x 23.5% (p=0.06) at 24h in tirofiban and placebo groups, respectively. This pilot study showed a trend toward reduction of NR associated with in-lab upfront use of tirofiban in STEMI patients treated with PPCI and paves the way for a full-scale study testing this hypothesis. Mesmo com abertura da artéria coronária culpada bem sucedida, a reperfusão miocárdica nem sempre sucede a intervenção coronariana percutânea primária (ICPP). Inibidores da glicoproteína IIb/IIIa são usados no tratamento do fenômeno de não reperfusão (NR), mas seu papel para preveni-lo não está comprovado. Avaliar o efeito

Identifying Nursing Diagnoses of fatigue, activity intolerance and decreased cardiac output in hospitalized patients with heart failure and verifying the association between the defining characteristics and the Nursing Diagnoses. A longitudinal and prospective study that followed hospitalized patients with heart failure for three weeks. The data collected through interviews and physical examinations were sent to expert nurses for diagnostic inference. Descriptive and inferential statistical analyses were carried out. Of the 72 patients, 68.0% were male and presented the nursing diagnosis of decreased cardiac output (62.5%) in the first week, reducing to 52.8% and 38% in the second and third weeks, respectively. Fatigue only appeared in one patient. Activity intolerance was the diagnosis that had the greatest discrepancy among the experts. Decreased cardiac output was associated to the defining characteristics: dyspnea, edema, jugular venous distension and reduced ejection fraction during all three weeks of evaluation. Decreased cardiac output was more prevalent in hospitalized patients with heart failure, and the associated defining characteristics were determining factors for this nursing diagnosis.

To identify the patient safety culture in pediatric emergencies from the perspective of the nursing team. A quantitative, cross-sectional survey research study with a sample composed of 75 professionals of the nursing team. Data was collected between September and November 2014 in three Pediatric Emergency units by applying the Hospital Survey on Patient Safety Culture instrument. Data were submitted to descriptive analysis. Strong areas for patient safety were not found, with areas identified having potential being: Expectations and actions from supervisors/management to promote patient safety and teamwork. Areas identified as critical were: Non-punitive response to error and support from hospital management for patient safety. The study found a gap between the safety culture and pediatric emergencies, but it found possibilities of transformation that will contribute to the safety of pediatric patients. Nursing professionals need to become protagonists in the process of replacing the current paradigm for a culture focused on safety. The replication of this study in other institutions is suggested in order to improve the current health care scenario.

Elective laparoscopic cholecystectomy has very low risk for infectious complications, ranging the infection rate from 0.4% to 1.1%. Many surgeons still use routine antibiotic prophylaxis. Evaluate the real impact of antibiotic prophylaxis in elective laparoscopic cholecystectomies in low risk patients. Prospective, randomized and double-blind study. Were evaluated 100 patients that underwent elective laparoscopic cholecystectomy divided in two groups: group A (n=50), patients that received prophylaxis using intravenous Cephazolin (2 g) during anesthetic induction and group B (n=50), patients that didn't receive any antibiotic prophylaxis. The outcome evaluated were infeccious complications at surgical site. The patients were reviewed seven and 30 days after surgery. There was incidence of 2% in infection complications in group A and 2% in group B. There was no statistical significant difference of infectious complications (p=0,05) between the groups. The groups were homogeneous and comparable. The use of the antibiotic prophylaxis in laparoscopic cholecystectomy in low risk patients doesn't provide any significant benefit in the decrease of surgical wound infection.

The study included 25 patients with mild-to-moderate COPD (68% male; mean age, 65 ± 8 years; mean FEV1, 73 ± 15% of predicted) and 25 with severe-to-very severe COPD (males, 56%; mean age, 69 ± 9 years; mean FEV1, 40 ± 18% of predicted). Comorbidities were recorded on the basis of data obtained from medical charts and clinical evaluations. Comorbidities were registered on the basis of data obtained from medical charts and clinical evaluations. The Charlson comorbidity index was calculated, and the Hospital Anxiety and Depression Scale (HADS) score was determined. Of the 50 patients evaluated, 38 (76%) had been diagnosed with at least one comorbidity, 21 (42%) having been diagnosed with at least one CVD. Twenty-four patients (48%) had more than one CVD. Eighteen (36%) of the patients were current smokers, 10 (20%) had depression, 7 (14%) had dyslipidemia, and 7 (14%) had diabetes mellitus. Current smoking, depression, and dyslipidemia were more prevalent among the patients with mild-to-moderate COPD than among those with severe-to-very severe COPD (p < 0.001, p = 0.008, and p = 0.02, respectively). The prevalence of high blood pressure, diabetes mellitus, alcoholism, ischemic heart disease, and chronic heart failure was comparable between the two groups. The Charlson comorbidity index and HADS scores did not differ between the groups. Comorbidities are highly prevalent in COPD, regardless of its severity. Certain risk factors for CVD, themselves classified as diseases (including smoking, dyslipidemia, and depression), appear to be more prevalent in patients with mild-to-moderate COPD.

to compare the results of urinary tract infection incidence, by means of the rate of indwelling urethral catheter use, and to identify microorganisms in urine cultures and surveillance cultures before and after the implementation of a clinical protocol for intensive care unit patients . urinary tract infection is defined as a positive urine culture > 105 CFU/mL, notified by the hospital infection control service, six months before and after the implementation of the protocol. The sample consisted of 47 patients, 28 reported before and 19 after implementation. The protocol established in the institution is based on the Ministry of Health manual to prevent healthcare-related infections; the goal is patient safety and improving the quality of health services. a negative linear correlation was observed between the later months of implementation and the reduction of reported cases of urinary tract infection, using the Spearman rank order coefficient (p = 0.045), and a reduction in the number of urine culture microorganisms (p = 0.026) using the Fisher exact test. educational interventions with implementation protocols in health institutions favor the standardization of maintenance of the invasive devices, which may reduce colonization and subsequent infections. comparar os resultados da incidência de infecção do trato urinário, por meio da taxa de utilização do cateter vesical de demora e identificar os micro-organismos na urocultura e cultura de vigilância antes e após a implementação de um protocolo assistencial em pacientes internados em unidade de terapia intensiva. definiu-se infecção do trato urinário pacientes com urocultura positiva >105 UFC/mL, notificados pelo Serviço de Controle de Infecção Hospitalar, seis meses antes e após a implementação do protocolo.

to examine the factors associated with problematic drug use among psychiatric outpatients. a cross-sectional study was carried out in two mental health services. Eligible individuals were patients of these mental health services, who used them within the data collection period. Instruments: standardized questionnaire with sociodemographic, social network, social harm, and clinical information; Alcohol, Smoking and Substance Involvement Screening Test; Barratt Impulsiveness Scale; Holmes and Rahe Stress Scale. Statistical analysis was performed using parametric statistics considering a significance level of p ≤ 0.05. Study participants were 243 patients, with 53.9% of these presenting problematic drug use. the most important independent predictors of problematic drug use were marital status (OR = 0.491), religious practice (OR = 0.449), satisfaction with financial situation (OR = 0.469), having suffered discrimination (OR = 3.821) and practicing sports activities in previous 12 months (OR = 2.25). the variables found to be predictors were those related to the social context of the patient, there, it is recommended that mental health services valorize psychosocial actions, seeking to know the social support network of patients, their modes of socialization, their financial needs, and their experiences of life and suffering. analisar os fatores associados ao consumo problemático de droga entre pacientes psiquiátricos ambulatoriais. estudo transversal em dois serviços de saúde mental.

To evaluate the usefulness of simple motor tasks such as hand grasping and tongue protrusion as predictors of extubation failure in critically ill neurological patients. This was a prospective cohort study conducted in the neurological ICU of a tertiary care hospital in the city of Porto Alegre, Brazil. Adult patients who had been intubated for neurological reasons and were eligible for weaning were included in the study. The ability of patients to perform simple motor tasks such as hand grasping and tongue protrusion was evaluated as a predictor of extubation failure. Data regarding duration of mechanical ventilation, length of ICU stay, length of hospital stay, mortality, and incidence of ventilator-associated pneumonia were collected. A total of 132 intubated patients who had been receiving mechanical ventilation for at least 24 h and who passed a spontaneous breathing trial were included in the analysis. Logistic regression showed that patient inability to grasp the hand of the examiner (relative risk = 1.57; 95% CI: 1.01-2.44; p < 0.045) and protrude the tongue (relative risk = 6.84; 95% CI: 2.49-18.8; p < 0.001) were independent risk factors for extubation failure. Acute Physiology and Chronic Health Evaluation II scores (p = 0.02), Glasgow Coma Scale scores at extubation (p < 0.001), eye opening response (p = 0.001), MIP (p < 0.001), MEP (p = 0.006), and the rapid shallow breathing index (p = 0.03) were significantly different between the failed extubation and successful extubation groups. The inability to follow simple motor commands is predictive of extubation failure in critically ill neurological patients. Hand grasping and tongue protrusion on command might be quick and easy bedside tests to identify neurocritical care patients who are candidates for extubation.

to assess the factors associated with the risk of fall in patients undergoing surgical procedures. quantitative and cross-sectional study carried out with 257 adult patients in a hospital in the state of Minas Gerais, Brazil. Data were collected using the sociodemographic and clinical questionnaire, the Morse Fall Scale, and the Quality of Recovery Score. Data were submitted to descriptive statistical analysis and multinomial logistic regression. The level of significance was set at 0.05. 35.4% of patients had high risk of falls, 38.9% had moderate risk and 25.7% had low risk. The mean value in the surgical recovery scale was 175.37 points and no patient presented poor surgical recovery. Regarding the results of the bivariate analysis, it was found that age (p<0.001), SAH (p<0.001) and diabetes (p=0.017) were positively associated with high risk of fall, whereas cancer (p=0.004) was positively associated with moderate risk of fall. Surgical recovery (p=0,008) was inversely associated with high risk of fall. the results of this study allowed the identification of five factors associated with the risk of fall in adults in the postoperative hospital stay. These findings may support the planning of nursing actions aimed at preventing the risk of fall in the postoperative period. evaluar los factores asociados al riesgo de caída en pacientes sometidos a procedimientos quirúrgicos. estudio cuantitativo, transversal, realizado en 257 pacientes adultos en un hospital de Minas Gerais, Brasil.

Atrial fibrillation (AF) takes place in 10-40% of patients undergoing coronary artery bypass grafting (CABG), and increases cardiovascular mortality. Enlargement of atrial chambers is associated with increased AF incidence, so patients with higher central venous pressure (CVP) are expected to have larger atrial distension, which increases AF incidence. To compare post-CABG AF incidence, following two CVP control strategies. Interventional, randomized, controlled clinical study. The sample comprised 140 patients undergoing CABG between 2011 and 2015. They were randomized into two groups, G15 and G20, with CVP maintained ≤ 15 cmH2O and ≤ 20 cmH2O, respectively. 70 patients were included in each group. The AF incidence in G15 was 8.57%, and in G20, 22.86%, with absolute risk reduction of 14.28%, and number needed to treat (NNT) of 7 (p = 0.03). Mortality (G15 = 5.71%; G20 = 11.42%; p = 0.07), hospital length of stay (G15 = 7.14 days; G20 = 8.21 days; p = 0.36), number of grafts (median: G15 = 3, G2 = 2; p = 0.22) and cardiopulmonary bypass use (G15 = 67.10%; G20 = 55.70%; p = 0.22) were statistically similar. Age (p = 0.04) and hospital length of stay (p = 0.001) were significantly higher in patients who developed AF in both groups. Keeping CVP low in the first 72 post-CABG hours reduces the relative risk of AF, and may be useful to prevent AF after CABG. A fibrilação atrial (FA) ocorre em 10-40% dos pacientes submetidos a cirurgia de revascularização miocárdica (RM), e eleva a mortalidade cardiovascular. Como o aumento dos átrios está associado ao aumento da incidência de FA, espera-se que pacientes com pressão venosa central (PVC) mais alta tenham maior distensão atrial, o que eleva a incidência dessa arritmia. Comparar a incidência de FA em pós-operatório de RM, seguindo duas estratégias de controle de PVC. Estudo clínico randomizado controlado intervencionista.

Background: Coronary artery bypass graft (CABG) is a standard surgical option for patients with diffuse and significant arterial plaque. This procedure, however, is not free of postoperative complications, especially pulmonary and cognitive disorders. Objective: This study aimed at comparing the impact of two different physiotherapy treatment approaches on pulmonary and cognitive function of patients undergoing CABG. Methods: Neuropsychological and pulmonary function tests were applied, prior to and following CABG, to 39 patients randomized into two groups as follows: Group 1 (control) - 20 patients underwent one physiotherapy session daily; and Group 2 (intensive physiotherapy) - 19 patients underwent three physiotherapy sessions daily during the recovery phase at the hospital. Non-paired and paired Student t tests were used to compare continuous variables. Variables without normal distribution were compared between groups by using Mann-Whitney test, and, within the same group at different times, by using Wilcoxon test. The chi-square test assessed differences of categorical variables. Statistical tests with a p value ≤ 0.05 were considered significant. Results: Changes in pulmonary function were not significantly different between the groups. However, while Group 2 patients showed no decline in their neurocognitive function, Group 1 patients showed a decline in their cognitive functions (P ≤ 0.01). Conclusion: Those results highlight the importance of physiotherapy after CABG and support the implementation of multiple sessions per day, providing patients with better psychosocial conditions and less morbidity.Fundamento: A cirurgia de revascularização miocárdica (CRM) é a opção cirúrgica padrão para pacientes com placas arteriais difusas e significativas.

Avaliar o desempenho do SXescore para predizer eventos cardíacos adversos maiores (MACE) em pacientes encaminhados para cineangiocoronariografia diagnóstica. Coorte prospectiva de 895 pacientes com suspeita de DAC encaminhados para cineangiocoronariografia diagnóstica eletiva de 2008 a 2011, em hospital universitário no Brasil. Os pacientes tiveram seus SXescores calculados e foram estratificados em três categorias: 'sem DAC significativa' (n = 495); SXescoreBAIXO-INTERMEDIÁRIO: < 23 (n = 346); e SXescoreALTO: ≥ 23 (n = 54). O desfecho primário foi composto de morte cardíaca, infarto do miocárdio e revascularização tardia. Os desfechos secundários foram MACE e morte por todas as causas. Em média, os pacientes foram acompanhados por 1,8 ± 1,4 anos. Desfecho primário ocorreu em 2,2%, 15,3% e 20,4% nos grupos 'sem DAC significativa', SXescoreBAIXO-INTERMEDIÁRIO e SXescoreALTO, respectivamente (p < 0,001). Morte por todas as causas foi significativamente mais frequente no grupo de SXescoreALTO comparado ao grupo 'sem DAC significativa', 16,7% e 3,8% (p < 0,001), respectivamente. Após ajuste para fatores de confusão, todos os desfechos permaneceram associados com o SXescore. O SXescore prediz independentemente MACE em pacientes submetidos a cineangiocoronariografia diagnóstica. Seu uso rotineiro nesse contexto poderia identificar pacientes de pior prognóstico.

The Effect of Oxygen Supply on the Dual Growth Kinetics of Acidithiobacillus thiooxidans under Acidic Conditions for Biogas Desulfurization

In this study, to simulate a biogas desulfurization process, a modified Monod-Gompertz kinetic model incorporating a dissolved oxygen (DO) effect was proposed for a sulfur-oxidizing bacterial (SOB) strain, Acidithiobacillus thiooxidans, under extremely acidic conditions of pH 2. The kinetic model was calibrated and validated using experimental data obtained from a bubble-column bioreactor. The SOB strain was effective for H2S degradation, but the H2S removal efficiency dropped rapidly at DO concentrations less than 2.0 mg/L. A low H2S loading was effectively treated with oxygen supplied in a range of 2%–6%, but a H2S guideline of 10 ppm could not be met, even with an oxygen supply greater than 6%, when the H2S loading was high at a short gas retention time of 1 min and a H2S inlet concentration of 5000 ppm. The oxygen supply should be increased in the aerobic desulfurization to meet the H2S guideline; however, the excess oxygen above the optimum was not effective because of the decline in oxygen efficiency. The model estimation indicated that the maximum H2S removal rate was approximately 400 ppm/%-O2 at the influent oxygen concentration of 4.9% under the given condition. The kinetic model with a low DO threshold for the interacting substrates was a useful tool to simulate the effect of the oxygen supply on the H2S removal and to determine the optimal oxygen concentration.

The objective of this study was to evaluate the association between psychological, hormonal, and genetic factors with the development of burning mouth syndrome (BMS) and secondary oral burning (SOB) in order to provide a better characterization and classification of these conditions. Cross sectional study. Patients with complaints of mouth burning registered at the Oral Diagnostic Service of the Federal University of Rio Grande do Norte between 2000 and 2013. The sample consisted of 163 subjects divided into a group of patients with BMS (n = 64) and a group of subjects with SOB (n = 99). The following variables were analyzed: passive and stimulated saliva flow, stress levels and phase, depression, anxiety, serum cortisol and dehydroepiandrosterone (DHEA) levels, and the presence of polymorphisms in the interleukin 6 (IL-6) gene. The results showed significant differences in the presence of xerostomia (p = 0.01), hyposalivation at rest (p < 0.001) and symptoms of depression (p = 0.033) between the two groups, which were more prevalent in the BMS group. DHEA levels were lower in the BMS group (p = 0.003) and were sensitive and specific for the diagnosis of this condition. Genetic analysis revealed no significant association between the polymorphisms analyzed and the development of BMS. These results suggest a possible role of depression, as well as of reduced DHEA levels, as associated factors for development of BMS. © 2016 American Academy of Pain Medicine. All rights reserved.

As probabilidades de sobrevida doença-específica em 60 meses foram calculadas com o método de Kaplan-Meier para três grupos de estadiamento. A importância dos fatores estudados foi avaliada por um modelo teórico hierarquizado após o ajuste de modelos de regressão múltipla de Cox. Foi estimada uma taxa de letalidade doença-específica em 60 meses de 86,0%. A probabilidade de sobrevida doença-específica em 60 meses variou de 25,0%, nos estádios iniciais, a 2,5%, no estádio IV. A situação funcional, a intenção e a modalidade do tratamento inicial foram os principais fatores prognósticos identificados na população estudada. As probabilidades de sobrevida doença-específica estimadas na amostra estudada foram muito baixas, e não foram identificados fatores que pudessem ser modificados após o diagnóstico visando uma melhora da sobrevida. A prevenção primária, como a redução da prevalência do tabagismo, ainda é a melhor forma de evitar que mais pessoas sofram as consequências do câncer de pulmão.

This was a descriptive observational study conducted at an intensive care unit in the Northeast region of Brazil, between November and December 2015. Data were gathered using the Pressure Ulcer Scale for Healing and a form to characterize and assess costs. Values in Brazilian reais (BRL) were converted into U.S. dollars at the exchange rate of USD 0.26/BRL. Univariate and bivariate analyses were conducted. The sample consisted of 15 patients with at least stage 2 ulcers. There was a significant reduction in costs with dressing materials between the initial and final assessments (p=0.002), with a mean of USD 11.9 (±7.4). The most common topical treatments used were essential fatty acids and papain. Cost reduction was proportional to the stage of pressure ulcer.

To investigate the effects of oral zinc supplementation on fatigue intensity and quality of life of patients during chemotherapy for colorectal cancer. A prospective, randomized, double-blinded, placebo-controlled study was conducted with 24 patients on chemotherapy for colorectal adenocarcinoma in a tertiary care public hospital. The study patients received zinc capsules 35mg (Zinc Group, n=10) or placebo (Placebo Group, n=14) orally, twice daily (70mg/day), for 16 weeks, from the immediate postoperative period to the fourth chemotherapy cycle. Approximately 45 days after surgical resection of the tumor, all patients received a chemotherapeutic regimen. Before each of the four cycles of chemotherapy, the Functional Assessment of Chronic Illness Therapy-Fatigue scale was completed. We used a linear mixed model for longitudinal data for statistical analysis. The scores of quality of life and fatigue questionnaires were similar between the groups during the chemotherapy cycles. The Placebo Group presented worsening of quality of life and increased fatigue between the first and fourth cycles of chemotherapy, but there were no changes in the scores of quality of life or fatigue in the Zinc Group. Zinc supplementation prevented fatigue and maintained quality of life of patients with colorectal cancer on chemotherapy.

Resumo Contexto As cardiopatias podem causar alterações no formato das ondas da ultrassonografia vascular (UV) em vasos periféricos. Essas alterações, tipicamente bilaterais e sistêmicas, são pouco conhecidas e estudadas. Objetivo Avaliar as ondas periféricas da UV de pacientes idosos para identificar alterações decorrentes de cardiopatias. Métodos Foram estudados 183 pacientes idosos submetidos a UV periférica no ano de 2014. Resultados Foram avaliados 102 mulheres (55,7%) e 81 homens (44,3%) com idade entre 60 e 91 anos (média de 70,4±7,2 anos). Encontraram-se alterações pela UV em 84 pacientes (45,9%). Foram identificadas 138 alterações de oito dos 13 tipos descritos na literatura: arritmia, onda bisferiens de pico sistólico, baixa velocidade de pico sistólico, pulsatilidade em veias femorais, bradicardia, taquicardia, onda de pulso parvus tardus e onda de pulso alternans. Houve baixa concordância entre a presença e a não presença de alterações na UV e na avaliação cardiológica. Na análise específica das alterações, os exames tiveram uma concordância variável, que foi boa para o achado de taquicardia, moderada para arritmia e baixa para bradicardia. Não houve concordância entre a UV e os exames cardiológicos para as demais alterações. Conclusões É possível identificar determinadas alterações cardíacas em idosos por meio da análise do formato das ondas periféricas da UV. É importante reconhecer e relatar a presença dessas alterações, pela possibilidade de alertar para um diagnóstico ainda não identificado nesses pacientes. Entretanto, mais estudos são necessários para que seja definida a importância das alterações no formato das ondas Doppler periféricas no reconhecimento de cardiopatias. PMID:29930591

El síndrome de caquexia cancerosa es responsable de la muerte de un número significativo de pacientes con cáncer. Se caracteriza por la presencia de una ingesta reducida, con inflamación sistémica y un metabolismo alterado. Los enfermos presentan característicamente una progresiva pérdida de peso y de masa muscular, junto a deterioro funcional. La pérdida muscular se debe a la combinación de reducción de la síntesis proteica con aumento de su degradación. Ello conduce tanto a un acortamiento como a una reducción en el área de la fibra muscular. Asimismo, existen datos que apoyan que selectivamente algunos de los tipos de fibra muscular se ven más afectados. Es necesario definir bien los valores de corte de sarcopenia para diagnosticar la pérdida muscular y existen diferentes métodos. El sistema de la ubiquitina-proteasoma parece desempeñar un papel predominante en la degradación de la proteína miofibrilar. La tendencia a perder masa muscular en los pacientes con caquexia cancerosa parece estar asociada a la activación de señales catabólicas por citoquinas proinflamatorias, así como por productos tumorales del tipo factor inductor de proteólisis. En referencia a los factores pronósticos, el riesgo de muerte está bien documentado en pacientes con sarcopenia y, especialmente, en aquellos con obesidad asociada a la sarcopenia. Asimismo, se ha establecido una relación directa entre la pérdida intensa de masa muscular y la supervivencia en pacientes con diferentes tipos de tumores del tipo de cáncer de páncreas, pulmón, tracto biliar o cáncer colorrectal. Respecto de la terapia en el síndrome de caquexia cancerosa, es factible que requiera tratamiento con varios grupos combinados que incluyan, junto al soporte nutricional, fármacos orexígenos, con efecto anabólico y antinflamatorio, asociados a intervenciones que estimulen el ejercicio físico.

To identify the length of perioperative fasting among patients submitted to gastrointestinal cancer surgeries. Retrospective cohort study, developed by consulting the medical records of 128 patients submitted to gastrointestinal cancer surgeries. The mean of total length of fasting was 107.6 hours. The total length of fasting was significantly associated with the number of symptoms presented before (p=0.000) and after the surgery (p=0.007), the length of hospital stay (p=0.000), blood transfusion (p=0.013), nasogastric tube (p=0.001) and nasojejunal tube (p=0,003), postoperative admission at ICU (p=0.002), postoperative death (p=0.000) and length of preoperative fasting (p=0.000). The length of fasting is associated with complications that affect the quality of the patients' postoperative recovery and nurses' work. The nursing team should be alert to this aspect and being responsible for overseeing the patients' interest, should not permit the unnecessary extension of fasting.

To assess the knowledge of multiprofesional residents in health about the security of the patient theme. Cross-sectional study, quantitative, developed with graduate courses/residence specialties of health in a public university of Paraná, Brazil. Participants (n=78) answered a questionnaire containing nine objective questions related to patient safety. Data were analyzed using descriptive statistics, in proportion measures. The minimum 75% of correct answers was considered the cutoff for positive evaluation. The sample was predominantly composed of young people from medical programs. Almost half of the items evaluated (n=5) achieved the established positive pattern, especially those who dealt with the hand hygiene moments (98.8%) and goal of the Patient Safety National Program (92.3%). The identification of the patient was the worst rated item (37.7%). In the analysis by professional areas, only the Nursing reached the standard of hits established.

Vaz, Nuno Alexandre Firmino

O principal objectivo deste trabalho consistiu no estudo da dinâmica termohalina do Canal do Espinheiro em funcao de dois forcamentos principais: mare e caudal fluvial, usando duas abordagens distintas: trabalho experimental e modelacao numerica. A propagacao da mare e o caudal fluvial do Rio Vouga sao determinantes no estabelecimento da estrutura horizontal da salinidade ao longo do canal. A estrutura termica horizontal ao longo do canal e, em grande parte, determinada pela variacao sazonal da temperatura da agua do Rio Vouga, bem como, pela variacao sazonal das condicoes meteorologicas devido a reduzida profundidade. Foi observada a formacao de fortes gradientes de salinidade (relacionados com a formacao de frentes estuarinas) numa regiao a cerca de 7-8 km da embocadura do canal, observando-se a sua migracao numa regiao de aproximadamente 1 km, dependendo do regime de mare. O balanco entre o transporte de sal de natureza advectiva e difusiva foi calculado, revelando que junto a embocadura os processos fisicos que mais contribuem para o transporte de sal sao a circulacao residual e o aprisionamento da agua em canais secundarios. Junto a foz do Rio Vouga os termos devidos a descarga fluvial e a circulacao gravitacional dominam o transporte de sal. Foi calibrado e validado um modelo numerico (Mohid, em modo 2D e 3D), sendo posteriormente utilizado para estudar a hidrologia do canal. Foi concedida particular atencao ao estudo da hidrologia em condicoes extremas de caudal fluvial e de mare. Os resultados da modelacao numerica permitiram numa primeira fase avaliar o bom desempenho do Mohid na reproducao dos escoamentos barotropicos na Ria de Aveiro, bem como na evolucao temporal das propriedades termohalinas da agua. Sob condicoes de caudal fluvial reduzido, a dinâmica do canal e essencialmente dominada pela mare. Com o aumento do caudal fluvial, a influencia da agua doce estende-se para jusante, estratificando a coluna de agua. As simulacoes 3D do Canal do

The EF also emerged as a predictor of induction of VT / VF: for each point increase in EF, there was a 4% reduction in the rate of sustained ventricular arrhythmia on EPS. Conclusions: Changes in the QRS-T angle and decreases in EF were associated with an increased risk of induction of VT / VF on EPS.Fundamento: O ângulo QRS-T mostra correlação com prognóstico em pacientes com insuficiência cardíaca e doença coronariana, traduzido por um aumento na mortalidade proporcional ao aumento na diferença entre os eixos do complexo QRS e da onda T no plano frontal. Até hoje, nenhuma informação a este respeito foi obtida em pacientes com cardiopatia chagásica. Objetivo: Correlacionar o ângulo QRS-T com a indução de taquicardia ventricular / fibrilação ventricular (TV / FV) em chagásicos durante estudo eletrofisiológico (EEF). Métodos: Estudo caso-controle em centro terciário. Pacientes sem indução de TV / FV ao EEF foram utilizados como controles. O ângulo QRS-T foi categorizado como normal (0-105º), limítrofe (105-135º) e anormal (135-180º). As diferenças entre os grupos foram analisadas pelo teste t ou teste de Mann-Whitney para variáveis contínuas, e teste exato de Fisher ou qui-quadrado para variáveis categóricas. Valores de p < 0,05 foram considerados significativos. Resultados: De 116 pacientes submetidos ao EEF, 37,9% foram excluídos por estarem com dados incompletos / prontuários inativos ou pela impossibilidade de se calcular corretamente o ângulo QRS-T (presença de bloqueio de ramo esquerdo e fibrilação atrial). De 72 pacientes incluídos, 31 induziram TV / FV ao EEF. Destes, o ângulo QRS-T se encontrava normal em 41,9%, limítrofe em 12,9% e anormal em 45,2%. No grupo de pacientes sem indução de TV / FV, o ângulo QRS-T se encontrava normal em 63,4%, limítrofe em 14,6% e anormal em 17,1% (p = 0,04).

Reliable measurement of basal energy expenditure (BEE) in liver transplant (LT) recipients is necessary for adapting energy requirements, improving nutritional status and preventing weight gain. Indirect calorimetry (IC) is the gold standard for measuring BEE. However, BEE may be estimated through alternative methods, including electrical bioimpedance (BI), Harris-Benedict Equation (HBE), and Mifflin-St. Jeor Equation (MSJ) that carry easier applicability and lower cost. To determine which of the three alternative methods for BEE estimation (HBE, BI and MSJ) would provide most reliable BEE estimation in LT recipients. Prospective cross-sectional study including dyslipidemic LT recipients in follow-up at a 735-bed tertiary referral university hospital. Comparisons of BEE measured through IC to BEE estimated through each of the three alternative methods (HBE, BI and MSJ) were performed using Bland-Altman method and Wilcoxon Rank Sum test. Forty-five patients were included, aged 58±10 years. BEE measured using IC was 1664±319 kcal for males, and 1409±221 kcal for females. Average difference between BEE measured by IC (1534±300 kcal) and BI (1584±377 kcal) was +50 kcal (p=0.0384). Average difference between the BEE measured using IC (1534±300 kcal) and MSJ (1479.6±375 kcal) was -55 kcal (p=0.16). Average difference between BEE values measured by IC (1534±300 kcal) and HBE (1521±283 kcal) was -13 kcal (p=0.326). Difference between BEE estimated through IC and HBE was less than 100 kcal for 39 of all 43patients. Among the three alternative methods, HBE was the most reliable for estimating BEE in LT recipients. Estimativa confiável do metabolismo basal em pacientes transplantados de fígado é necessária para adaptar os requerimentos energéticos, melhorar o estado nutricional e prevenir ganho de peso. Calorimetria indireta (CI) é o padrão-ouro para a medição do metabolismo basal. No entanto, ele pode ser estimado utilizando-se métodos alternativos

Los costos de la atención médica pueden alcanzar niveles tales que marginen a algunos pacientes de los beneficios del avance científico y tecnológico. Las razones de estos elevados costos son diversas y en la mayoría de los casos no está en manos de los médicos moderarlos. En este escrito se proponen algunas acciones que los médicos podemos realizar para disminuir los costos de la atención médica. La magnitud del ahorro que se puede alcanzar con estas medidas es modesta, puesto que la mayor parte de los costos no dependen de los médicos, pero se trata de ofrecer nuestra contribución.

The Behavioral Risk Factor Surveillance System (BRFSS) survey is used to estimate chronic obstructive pulmonary disease (COPD) prevalence and could be expanded to describe respiratory symptoms in the general population and to characterize persons with or at high risk for the disease. Tobacco duration and respiratory symptom questions were added to the 2012 South Carolina BRFSS. Data concerning sociodemographics, chronic illnesses, health behaviors, and respiratory symptoms were collected in 9438 adults ≥ 35 years-old. Respondents were categorized as having COPD, high risk, or low risk for the disease. High risk was defined as no self-reported COPD, ≥ 10 years’ tobacco use, and ≥ 1 respiratory symptom (frequent productive cough or shortness of breath (SOB), or breathing problems affecting activities). Prevalence of self-reported and high-risk COPD were 9.1% and 8.0%, respectively. Overall, 17.3%, 10.6%, and 5.2% of all respondents reported activities limited by breathing problems, frequent productive cough, and frequent SOB, respectively. The high-risk group was more likely than the COPD group to report a productive cough and breathing problems limiting activities as well as being current smokers, male, and African-American. Health impairment was more severe in the COPD than the high-risk group, and both were worse than the low-risk group. Conclusions Persons at high risk for COPD share many, but not all, of the characteristics of persons diagnosed with the disease. Additional questions addressing smoking duration and respiratory symptoms in the BRFSS identifies groups at high risk for having or developing COPD who may benefit from smoking cessation and case-finding interventions.

to evaluate whether bacterial genus is a risk factor for major amputation in patients with diabetic foot and infected ulcer. we conducted a case-control, observational study of 189 patients with infected ulcers in diabetic feet admitted to the Vascular Surgery Service of the Risoleta Tolentino Neves Hospital, from January 2007 to December 2012. The bacteriological evaluation was performed in deep tissue cultures from the lesions and amputation was considered major when performed above the foot'smiddle tarsus. the patients'mean age was 61.9±12.7 years; 122 (64.6%) were men. The cultures were positive in 86.8%, being monomicrobial in 72% of the cases. In patients with major amputation, Acinetobacter spp. (24.4%), Morganella spp. (24.4%), Proteus spp. (23.1%) and Enterococcus spp. (19.2%) were the most frequent types of bacteria. The most commonly isolated species were Acinetobacter baumannii, Morganella morganii, Pseudomonas aeruginosa and Proteus mirabilis. As predictors of major amputation, we identified the isolation of the generaAcinetobacter spp. and Klebsiella spp., serum creatinine ≥1.3mg/dl and hemoglobin <11g/dl. the bacterial genera Acinetobacter spp. and Klebsiella spp. identified in infected ulcers of patients with diabetic foot were associated with a higher incidence of major amputation. avaliar se gênero bacteriano é fator de risco para amputação maior em pacientes com pé diabético e úlcera infectada. estudo observacional do tipo caso-controle de 189 pacientes com úlcera infectada em pé diabético admitidos pelo Serviço de Cirurgia Vascular do Hospital Risoleta Tolentino Neves, no período de janeiro de 2007 a dezembro de 2012.

Geological and structural conditions of localization, hydrothermal metasomatic alteration, and mineralization of the Petropavlovskoe gold deposit (Novogodnenskoe ore field) situated in the northern part of the Lesser Ural volcanic-plutonic belt, which is a constituent of the Middle Paleozoic island-arc system of the Polar Urals, are discussed. The porphyritic diorite bodies pertaining to the late phase of the intrusive Sob Complex play an ore-controlling role. The large-volume orebodies are related to the upper parts of these intrusions. Two types of stringer-disseminated ores have been revealed: (1) predominant gold-sulfide and (2) superimposed low-sulfide-gold-quartz ore markedly enriched in Au. Taken together, they make up complicated flattened isometric orebodies transitory to linear stockworks. The gold potential of the deposit is controlled by pyrite-(chlorite)-albite metasomatic rock of the main productive stage, which mainly develops in a volcanic-sedimentary sequence especially close to the contacts with porphyritic diorite. The relationships between intrusive and subvolcanic bodies and dating of individual zircon crystals corroborate a multistage evolution of the ore field, which predetermines its complex hydrothermal history. Magmatic activity of mature island-arc plagiogranite of the Sob Complex and monzonite of the Kongor Complex initiated development of skarn and beresite alterations accompanied by crystallization of hydrothermal sulfides. In the Early Devonian, due to emplacement of the Sob Complex at a depth of approximately 2 km, skarn magnetite ore with subordinate sulfides was formed. At the onset of the Middle Devonian, the large-volume gold porphyry Au-Ag-Te-W ± Mo,Cu stockworks related to quartz diorite porphyry—the final phase of the Sob Complex— were formed. In the Late Devonian, a part of sulfide mineralization was redistributed with the formation of linear low-sulfide quartz vein zones. Isotopic geochemical study has shown that the

The patients underwent pleural catheter insertion followed by bedside pleurodesis. Chest CT scans were performed twice: immediately before pleurodesis (iCT) and 30 days after pleurodesis (CT30). Catheter positioning was categorized based on iCT scans as posterolateral, anterior, fissural, and subpulmonary. We used the pleural volume on iCT scans to estimate early lung expansion and the difference between the pleural volumes on CT30 and iCT scans to evaluate radiological success of pleurodesis. Clinical pleurodesis success was defined as no need for any other pleural procedure. Of the 131 eligible patients from the original study, 85 were included in this nested study (64 women; mean age: 60.74 years). Catheter tip positioning was subpulmonary in 35 patients (41%), anterior in 23 (27%), posterolateral in 17 (20%), and fissural in 10 (12%). No significant differences were found among the groups regarding early lung expansion (median residual pleural cavity = 377 mL; interquartile range: 171-722 mL; p = 0.645), radiological success of pleurodesis (median volume = 33 mL; interquartile range: -225 to 257 mL; p = 0.923), and clinical success of pleurodesis (85.8%; p = 0.676). Our results suggest that the position of the tip of the pleural catheter influences neither early lung expansion nor bedside pleurodesis success in patients with RMPE.

The ultraportable echocardiogram machine, with relevant portability and easiness in performing diagnoses, when in experienced hands, may contribute to the reliability of preoperative evaluation in noncardiac surgeries. To assess cardiac function parameters in patients aged older than 60 years, candidates of elective noncardiac surgeries, classified as ASA1 or ASA 2 according to surgical risk. A total of 211 patients referred for elective surgeries, without suspicion of previous heart diseases, were included in the study. Assessment of patients was conducted by conventional echocardiogram using the ultraportable V Scan (GE) device right after the pre-anesthetic clinical evaluation. We assessed the clinical impact of echocardiography results by using a questionnaire addressed to the anesthetist. Mean age of patients was 68.9 ± 7.0 years, 154 were women. The most frequent surgeries were: a) facectomy - cataract - 18; b) inguinal hernia surgery - 18; c) Cholecystectomy - 16. We found 58 normal tests (27.5%), 70 (33.2%) with mild valve reflux, and 83 (39.3%) with relevant abnormality, such as increase in heart chamber size, global and/or segmental contractile dysfunction, significant valve dysfunction or other unspecified. Test results caused delay of surgical procedure for a more detailed cardiac evaluation in 20 (9.5%) patients, and change in anesthetic management in 7 (3.3%). There was a considerable clinical impact with the use of the ultraportable echocardiography, since one out of every ten patients evaluated had their clinical management changed due to the detection of previously unsuspected, significant heart diseases, with the potential for severe complications. O ecocardiógrafo ultraportátil, com importante mobilidade e facilidade diagnóstica em mãos experientes pode contribuir para a segurança na avaliação pré-operatória em cirurgias não cardíacas.

� comparar resultados da lobectomia pulmonar por videotoracoscopia com a robótica. O programa de cirurgia robótica do Instituto do Câncer do Estado de São Paulo, localizado na cidade de São Paulo (SP), foi uma iniciativa multidisciplinar que envolveu diversas especialidades cirúrgicas e equipes de anestesia, enfermagem e engenharia clínica. Nesta análise, avaliamos os pacientes incluídos no braço lobectomia robótica durante os primeiros três meses do estudo (de abril a junho de 2015). Dez pacientes foram incluídos nesta análise. Eram oito mulheres e dois homens. A média de idade foi de 65,1 anos. Todos apresentavam tumores periféricos. Foram realizadas lobectomia superior direita, em quatro pacientes; lobectomia inferior direita, em quatro; e lobectomia superior esquerda, em dois. Os tempos cirúrgicos variaram bastante (variação, 135-435 min). Não foi necessária a conversão para técnica aberta ou videotoracoscópica em nenhum paciente. Não foram observadas complicações intraoperatórias. Apenas o primeiro paciente foi encaminhado à UTI no pós-operatório. Não houve mortalidade nem reinternações em 30 dias após a alta. A única complicação pós-operatória observada foi dor torácica (grau 3), em dois pacientes. O exame anatomopatológico revelou a ressecção completa do tumor em todos os casos. A implantação de um programa de cirurgia torácica robótica, quando há integração e treinamento adequado de todas as equipes envolvidas, é factível e pode reduzir a morbidade e a mortalidade.

Neste trabalho foram produzidos nanocompositos de AlSiC misturando aluminio puro com nano particulas de SiC com diâmetro de 45 - 55 nm, usando, de forma sequencial, a tecnica da metalurgia do po e a compactacao por "Spark Plasma Sintering". O composito obtido apresentava graos com 100 nm de diâmetro, encontrandose as particulas de SiC localizadas, principalmente, nas fronteiras de grao. O nanocomposito sob a forma de provetes cilindricos foi submetido a testes de compressao uniaxial e a testes de nanoindentacao para analisar a influencia das nanoparticulas de SiC, da fracao volumica de acido estearico e do tempo de moagem, nas propriedades mecânicas do material. Para efeitos de comparacao, utilizouse o comportamento mecânico do Al puro processado em condicoes similares e da liga de aluminio AA1050O. A tensao limite de elasticidade do nanocomposito com 1% Vol./Vol. de SiC e dez vezes superior a do AA1050. O refinamento de grao a escala nano constitui o principal mecanismo de aumento de resistencia mecânica. Na realidade, o Al nanocristalino sem reforco de particulas de SiC, apresenta uma tensao limite de elasticidade sete vezes superior a da liga AA1050O. A adicao de 0,5 % Vol./Vol. e de 1 % Vol./Vol. de SiC conduzem, respetivamente, ao aumento da tensao limite de elasticidade em 47 % e 50%. O aumento do tempo de moagem e a adicao de acido estearico ao po durante a moagem conduzem apenas a um pequeno aumento da tensao de escoamento. A dureza do material medida atraves de testes de nanoindentacao confirmaram os dados anteriores. A estabilidade das microestruturas do aluminio puro e do nanocomposito AlSiC, foi testada atraves de recozimento de restauracao realizado as temperaturas de 150 °C e 250 °C durante 2 horas. Aparentemente, o tratamento termico nao influenciou as propriedades mecânicas dos materiais, excepto do nanocomposito com 1 % Vol./Vol. de SiC restaurado a temperatura de 250 °C, para o qual se observou uma reducao da tensao limite de elasticidade

Los defectos craneales secundarios a traumatismos son frecuentes. Por lo común se reparan de forma secundaria por sintomatología como el síndrome del paciente trepanado, por protección cerebral y por el aspecto cosmético. Históricamente se han utilizado diversos materiales para la reconstrucción. Se presentan cinco casos de pacientes reconstruidos con implantes personalizados de polieteretercetona (PEEK) o polimetilmetacrilato poroso (PMMA). Las localizaciones afectaron el frontal, el borde orbitario superior y el techo orbitario en cuatro casos, y la porción lateral del frontal, la zona temporoparietal y el borde del occipital en un caso. La reconstrucción en cuatro pacientes fue entre 6 y 12 meses después de la lesión, y en un caso después de 25 años. En dos casos se requirió expansión tisular antes de colocar el implante. Cuatro pacientes evolucionaron favorablemente, con mejoría de los síntomas neurológicos, forma y contorno adecuados, así como un proceso de cicatrización adecuada de los colgajos de piel cabelluda. Un paciente presentó infección por Staphylococcus aureus, atribuida a la presencia de un mucocele y una fístula de la vía aérea a la cavidad craneal, lo que hizo necesario retirar el implante. Los implantes personalizados son un recurso útil para defectos óseos craneales. Brindan resultados satisfactorios desde el punto de vista funcional y cosmético. Deben tomarse precauciones respecto al tratamiento de las lesiones que afecten el seno frontal, para evitar la comunicación entre la vía aérea y la cavidad craneal. Cranial defects due to trauma are frequent. They are usually repaired in a secondary fashion due to features such as syndrome of the trephined, for brain protection and for cosmetic purposes.

Patients at end stage renal disease have higher levels of inflammation and oxidative stress than the general population. Many factors contribute to these issues, and the parathyroid hormone (PTH) is also implicated. The study was conducted in order to assess the relationship between PTH levels and inflammation and oxidative stress in hemodialysis patients. Cross-sectional study with patients of two hemodialysis facilities in Londrina, Brazil. Patients with other conditions known to generate oxidative stress and inflammation were excluded. Blood levels of PTH and biochemical parameters of inflammation (interleukins 1 and 6, tumor necrosis factor-alpha) and oxidative stress (total plasma antioxidant capacity, malonic dialdehyde, lipid hydroperoxidation, advanced oxidation protein products, quantification of nitric oxide metabolites, and 8-isoprostane) were measured before a dialysis session. Then, we made correlation analyses between PTH levels - either as the continuous variable or categorized into tertiles-, and inflammatory and oxidative stress biomarkers. PTH did not show any correlation with the tested inflammation and oxidative stress parameters, nor as continuous variable neither as categorical variable. In this descriptive study, the results suggest that the inflammation and oxidative stress of hemodialysis patients probably arise from mechanisms other than secondary hyperparathyroidism. Pacientes com doença renal em estágio terminal têm níveis de inflamação e estresse oxidativo maiores do que a população geral.

To evaluate the vital capacity after two chest therapy techniques in patients undergoing abdominal surgical. A prospective randomized study carried out with patients admitted to the Intensive Care Unit after abdominal surgery. We checked vital capacity, muscular strength using the Medical Research Council scale, and functionality with the Functional Independence Measure the first time the patient was breathing spontaneously (D1), and also upon discharge from the Intensive Care Unit (Ddis). Between D1 and Ddis, respiratory therapy was carried out according to the randomized group. We included 38 patients, 20 randomized to Positive Intermittent Pressure Group and 18 to Volumetric Incentive Spirometer Group. There was no significant gain related to vital capacity of D1 and Ddis of Positive Intermittent Pressure Group (mean 1,410mL±547.2 versus 1,809mL±692.3; p=0.979), as in the Volumetric Incentive Spirometer Group (1,408.3mL±419.1 versus 1,838.8mL±621.3; p=0.889). We observed a significant improvement in vital capacity in D1 (p<0.001) and Ddis (p<0.001) and in the Functional Independence Measure (p<0.001) after respiratory therapy. The vital capacity improvement was not associated with gain of muscle strength. Chest therapy, with positive pressure and volumetric incentive spirometer, was effective in improving vital capacity of patients submitted to abdominal surgery.

We constructed random forest classifiers employing either the traditional method of scoring semantic fluency word lists or new methods. These classifiers were then compared in terms of their ability to diagnose Alzheimer disease (AD) or to prognosticate among individuals along the continuum from cognitively normal (CN) through mild cognitive impairment (MCI) to AD. Semantic fluency lists from 44 cognitively normal elderly individuals, 80 MCI patients, and 41 AD patients were transcribed into electronic text files and scored by four methods: traditional raw scores, clustering and switching scores, "generalized" versions of clustering and switching, and a method based on independent components analysis (ICA). Random forest classifiers based on raw scores were compared to "augmented" classifiers that incorporated newer scoring methods. Outcome variables included AD diagnosis at baseline, MCI conversion, increase in Clinical Dementia Rating-Sum of Boxes (CDR-SOB) score, or decrease in Financial Capacity Instrument (FCI) score. Receiver operating characteristic (ROC) curves were constructed for each classifier and the area under the curve (AUC) was calculated. We compared AUC between raw and augmented classifiers using Delong's test and assessed validity and reliability of the augmented classifier. Augmented classifiers outperformed classifiers based on raw scores for the outcome measures AD diagnosis (AUC .97 vs. .95), MCI conversion (AUC .91 vs. .77), CDR-SOB increase (AUC .90 vs. .79), and FCI decrease (AUC .89 vs. .72). Measures of validity and stability over time support the use of the method. Latent information in semantic fluency word lists is useful for predicting cognitive and functional decline among elderly individuals at increased risk for developing AD. Modern machine learning methods may incorporate latent information to enhance the diagnostic value of semantic fluency raw scores. These methods could yield information valuable for patient care and clinical

Highly educated participants with normal cognition show lower incidence of Alzheimer's disease (AD) than poorly educated participants, whereas longitudinal studies involving AD have reported that higher education is associated with more rapid cognitive decline. We aimed to evaluate whether highly educated amnestic mild cognitive impairment (aMCI) participants show more rapid cognitive decline than those with lower levels of education. A total of 249 aMCI patients enrolled from 31 memory clinics using the standard assessment and diagnostic processes were followed with neuropsychological evaluation (duration 17.2 ± 8.8 months). According to baseline performances on memory tests, participants were divided into early-stage aMCI (-1.5 to -1.0 standard deviation (SD)) and late-stage aMCI (below -1.5 SD) groups. Risk of AD conversion and changes in neuropsychological performances according to the level of education were evaluated. Sixty-two patients converted to AD over a mean follow-up of 1.43 years. The risk of AD conversion was higher in late-stage aMCI than early-stage aMCI. Cox proportional hazard models showed that aMCI participants, and late-stage aMCI participants in particular, with higher levels of education had a higher risk of AD conversion than those with lower levels of education. Late-stage aMCI participants with higher education showed faster cognitive decline in language, memory, and Clinical Dementia Rating Sum of Boxes (CDR-SOB) scores. On the contrary, early-stage aMCI participants with higher education showed slower cognitive decline in MMSE and CDR-SOB scores. Our findings suggest that the protective effects of education against cognitive decline remain in early-stage aMCI and disappear in late-stage aMCI.

The sulphur-based bioleaching process using sulphur-oxidizing bacteria (SOB) has been demonstrated to be a feasible technology for removing heavy metals from contaminated sediments, but the excess sulphur application will lead to the re-acidification of bioleached sediments. The objective of the present study was to examine the effect of sulphur concentration on the bioleaching of heavy metals from contaminated sediments, with the ultimate purpose of minimizing the sulphur addition. The results showed that the inoculation of 7% of indigenous SOB, containing 3.6 x 10(8) colony forming units (CFU) mL(-1), and addition of elemental sulphur as a substrate (0.5 to 7.0 g L(-1)) resulted in a sharp decrease in sediment pH from an initial pH 8.0 to pH 1.4-2.4 and an increase in ORP (oxidation-reduction potential) from -10 mV to 500 mV within 10 days of bioleaching. Although the increase in sulphur concentration enhanced the rates of pH reduction and ORP elevation, the bioleaching process with the addition of 3.0 g L(-1) of sulphur was already sufficient to reach conditions of acidity (pH < 2.0) and ORP (500 mV) necessary for a satisfactory removal of metals, and, at day 10, 71.8% of Cu, 58.2% of Zn, and 25.3% of Cr were removed from the sediments. During the bioleaching process, Zn removal increased with a reduction in pH, whereas the removal of Cu and Cr increased not only with a reduction in pH but also with an increase in ORP. Results of sequential selective extraction indicated that the final levels of metal removals were dependent on their speciation distribution in the original sediments, and after bioleaching those unremoved metals in the bioleached sediments mainly existed in the residual fraction.

Introducción: las lesiones intraepiteliales escamosas (LIE) son un estado de transición hacia el cáncer cervicouterino (CaCu) y un déficit de micronutrientes puede acelerar este proceso. Por ello, determinar la existencia de este déficit y conocer qué factores se asocian permitiría una posible prevención en esta población de riesgo.Objetivo: determinar la presencia de alguna deficiencia de micronutrientes involucrados en el proceso anticancerígeno y asociar este déficit con hábitos y factores demográficos en pacientes con LIE de Ciudad Juárez, Chihuahua, México.Métodos:en un estudio transversal analítico fueron seleccionadas 102 pacientes con LIE. Se realizó una encuesta dietaría (recordatorio de 24 horas) para estimar la ingesta de micronutrientes. La deficiencia fue determinada con un consumo < 75% de la ingesta diaria recomendada o sugerida (IDR o IDS) en México. Algunos hábitos y factores demográficos fueron obtenidos mediante la entrevista con la paciente. Se realizó un modelo de regresión logística para asociar la presencia de deficiencia con factores que afectan a la ingesta o incrementan el requerimiento de micronutrientes.Resultados:el retinol, ácido fólico, zinc, vitaminas C y E, considerados como micronutrientes en el proceso anticancerígeno del CaCu, se encontraron por debajo del 75% de la IDR. Aquellas mujeres con sobrepeso, obesidad y amas de casa se asociaron significativamente con la deficiencia de micronutrientes.Conclusión: el sobrepeso, la obesidad y la ocupación han sido asociados para presentar deficiencias de micronutrientes en este estudio. Estas variables convergen en una posible inseguridad alimentaria, la cual podría asociarse al incremento de incidencia de CaCu en México.

Estimating the incidence rate of pressure ulcers and verifying factors associated with this occurrence in a cohort of hospitalized patients. This is a cohort study in which the considered outcome was the time until pressure ulcer occurrence. Estimated effect of the variables on the cumulative incidence ratio of the outcome was performed using the Cox proportional hazards model. Variable selection occurred via the Logrank hypothesis test. The sample consisted of 442 adults, with 25 incidents of pressure ulcers. Patients with high scores on the Braden scale presented a higher risk of pressure ulcer incidence when compared to those classified into the low score category. These results reinforce the importance of using the Braden Scale to assist in identifying patients more likely to develop pressure ulcers.

Pleuroparenchymal fibroelastosis (PPFE) is a rare lung disease. It can be idiopathic or associated with any one of various conditions. To our knowledge, this is the first report of two cases of PPFE in Brazil. Our first patient presented with pleural and subpleural fibrosis in the upper lobes; a spiculated nodule in the left upper lobe; and a mild reticular pattern in the lower lobes. Surgical lung biopsy revealed PPFE in the upper lobes, including the nodule, and unclassified interstitial pneumonia in the left lower lobe. Our second patient had a history of exposure to domestic birds, indicating a risk of hypersensitivity pneumonitis, and presented with advanced lung disease, predominantly in the upper lobes, together with subpleural fibrosis.That patient underwent lung transplantation. In the explant specimen, PPFE and granulomas were identified, suggesting hypersensitivity pneumonitis as an associated cause. RESUMO A fibroelastose pleuroparenquimatosa (FEPP) é uma doença pulmonar rara, podendo ser idiopática ou associada a diversas condições. Pelo que sabemos, este é o primeiro relato de dois casos de FEPP no Brasil. Nosso primeiro paciente apresentava fibrose pleural e subpleural nos lobos superiores, um nódulo espiculado no lobo superior esquerdo e um padrão reticular discreto nos lobos inferiores. A biópsia pulmonar cirúrgica demonstrou FEPP nos lobos superiores, incluindo no nódulo, e pneumonia intersticial não classificada no lobo inferior esquerdo. Nosso segundo paciente tinha história de exposição a aves domésticas, indicando um risco de pneumonite de hipersensibilidade, e doença pulmonar avançada predominando em lobos superiores, com fibrose subpleural. Esse paciente foi submetido a transplante pulmonar. No espécime do explante, FEPP e granulomas foram identificados, sugerindo pneumonite de hipersensibilidade como causa associada.

In patients with severe respiratory failure, either hypoxemic or hypercapnic, life support with mechanical ventilation alone can be insufficient to meet their needs, especially if one tries to avoid ventilator settings that can cause injury to the lungs. In those patients, extracorporeal membrane oxygenation (ECMO), which is also very effective in removing carbon dioxide from the blood, can provide life support, allowing the application of protective lung ventilation. In this review article, we aim to explore some of the most relevant aspects of using ECMO for respiratory support. We discuss the history of respiratory support using ECMO in adults, as well as the clinical evidence; costs; indications; installation of the equipment; ventilator settings; daily care of the patient and the system; common troubleshooting; weaning; and discontinuation. RESUMO Em pacientes com insuficiência respiratória grave (hipoxêmica ou hipercápnica), o suporte somente com ventilação mecânica pode ser insuficiente para suas necessidades, especialmente quando se tenta evitar o uso de parâmetros ventilatórios que possam causar danos aos pulmões. Nesses pacientes, extracorporeal membrane oxygenation (ECMO, oxigenação extracorpórea por membrana), que também é muito eficaz na remoção de dióxido de carbono do sangue, pode manter a vida, permitindo o uso de ventilação pulmonar protetora. No presente artigo de revisão, objetivamos explorar alguns dos aspectos mais relevantes do suporte respiratório por ECMO. Discutimos a história do suporte respiratório por ECMO em adultos; evidências clínicas; custos; indicações; instalação do equipamento; parâmetros ventilatórios; cuidado diário do paciente e do sistema; solução de problemas comuns; desmame e descontinuação.

To assess the impact that educational interventions to improve inhaler techniques have on the clinical and functional control of asthma and COPD, we evaluated 44 participants before and after such an intervention. There was a significant decrease in the number of errors, and 20 patients (46%) significantly improved their technique regarding prior exhalation and breath hold. In the asthma group, there were significant improvements in the mean FEV1, FVC, and PEF (of 6.4%, 8.6%, and 8.3% respectively). Those improvements were accompanied by improvements in Control of Allergic Rhinitis and Asthma Test scores but not in Asthma Control Test scores. In the COPD group, there were no significant variations. In asthma patients, educational interventions appear to improve inhaler technique, clinical control, and functional control. RESUMO Para avaliar o impacto do ensino da técnica inalatória no controle clínico e funcional de pacientes com asma ou DPOC, incluíram-se 44 participantes antes e após essa intervenção. Houve uma diminuição significativa no número de erros cometidos, sendo que 20 pacientes (46%) melhoraram significativamente sua técnica na expiração prévia e apneia final. No grupo asma, houve significativa melhora nas médias de FEV1 (6,4%), CVF (8,6%) e PFE (8,3%), e essa melhora correlacionou-se com os resultados no Control of Allergic Rhinitis and Asthma Test, mas não com os do Asthma Control Test. No grupo DPOC, não houve variações significativas. O ensino da técnica inalatória parece melhorar seu desempenho e os controles clínico e funcional em pacientes com asma.

Consensus on updating immunizations in patients with primary immunodeficiencies

PubMed

2018-04-01

Las inmunodeficiencias primarias (IDP) constituyen un grupo de enfermedades hereditarias que afectan el número y/o la función de los distintos componentes del sistema inmune. Su prevalencia es de 1:1000-2000 nacimientos. Comprenden defectos de la inmunidad adaptativa, defectos de la inmunidad innata, inmunodeficiencias con fenotipos característicos, trastornos de la regulación inmune, síndromes autoinflamatorios, defectos de los fagocitos y del sistema del complemento y defectos considerados fenocopias de IDP. La vacunación con vacunas inactivadas es segura y puede ser efectiva en muchas inmunodeficiencias; las vacunas vivas atenuadas pueden no ser protectoras en ciertas IDP o presentarse como enfermedad vacunal asociada a la inmunización, lo que conlleva una alta morbimortalidad. Con el objetivo de actualizar las recomendaciones de vacunas en pacientes con IDP, el Comité Nacional de Infectología y el Grupo de Trabajo de Inmunología trabajaron sobre las vacunas que podían indicarse a estos pacientes, convivientes y el equipo de salud.

dentro do complexo muscular do elevador do ânus com mínima dissecção. Não há consenso na literatura sobre o melhor tratamento dessa fístula. Avaliar a anorretoplastia laparoscópica e o selamento bipolar da fístula retourinária. Ela foi realizada de acordo com a descrição original de Georgeson1. Utilizou-se o acesso infraumbilical com portal de 10 mm para a ótica de 30º. O pneumoperitônio foi estabelecido com pressão de 8-10 cm de H2O. Dois trocárteres adicionais de 5 mm foram colocados à direita e à esquerda da cicatriz umbilical. A dissecção foi iniciada na reflexão peritoneal usando Ligasure(r). Com a redução do calibre do reto distalmente, foi identificada a fístula para a o trato urinário. O local do novo ânus foi definido por meio da localização do complexo muscular do esfíncter anal externo, utilizando-se estimulador eletro muscular externamente. Por fim, foi confeccionada uma anastomose entre o reto e o novo local do ânus. Uma sonda uretral de Foley foi deixada durante sete dias. Sete meninos foram operados, seis com fístula retoprostática e um retovesical. O período de seguimento variou de um a quatro anos. Os dois últimos pacientes operados foram submetidos ao selamento bipolar da fístula entre o reto e a uretra, sem suturas ou ligadura cirúrgica com pontos. No seguimento em longo prazo não houve evidências de fístulas urinárias. Há benefícios da anorretoplastia laparoscópica para o tratamento de anomalia anorretal. O uso de uma fonte de energia bipolar que promova o selamento da fístula retourinária propiciou redução significativa do tempo cirúrgico e tornou o procedimento mais elegante.

O presente trabalho, sobre a intervenção de metodologias de ensino, foi desenvolvido na Escola Estadual Colônia dos Pescadores, na cidade de Caraguatatuba - SP, em três turmas do terceiro ano do Ensino Médio, perfazendo um total de 119 educandos, entre 16 e 19 anos. Antes de iniciar-se a intervenção, um questionário de vinte perguntas objetivas e dissertativas foi desenvolvido, aplicado pelo professor da classe, que ministrou as aulas correspondentes. Este questionário foi o mesmo em todas as três classes com o objetivo de diagnosticar o conhecimento prévio dos alunos sobre Astronomia. Começando a intervenção nas turmas, o professor envolvido usou três diferentes metodologias de ensino: (A) em forma de seminários, elaborados e apresentados pelos alunos, nos quais o professor fazia apenas as intervenções necessárias, (B) na forma tradicional, com a ajuda de multimídia para o desenvolvimento das aulas e a terceira (C) a tradicional, fazendo uso exclusivo de lousa e giz. No final do trabalho os alunos responderam o mesmo questionário novamente, de modo que os três métodos utilizados puderam ser comparados. Os resultados apresentados após a intervenção foram melhores que os resultados iniciais indicando a ocorrência de uma aprendizagem significativa. Quando os estudantes foram inicialmente questionados sobre quantos planetas existem no nosso sistema solar, a classe A obteve 39% de respostas certas, a classe B 48% e a classe C 46%, mas após o desenvolvimento das atividades, as classes obtiveram respectivamente 94%, 97 % e 90% de aproveitamento. No término do bimestre, foi sugerido aos educandos que elaborassem uma história em quadrinhos, a qual serviu para averiguar se os conceitos inicialmente observados foram alterados e se novos foram agregados. A análise das histórias foi dividida em três partes: Criatividade; Temas abordados; Emprego correto dos conceitos estudados. Ao final quatorze histórias foram confeccionadas. O aprendizado foi tão significativo que os alunos produzira m histórias em quadrinhos, com informações muito ricas. Outro dado muito importante é que, apesar da Astronomia ser um tema amplamente recomendado, não é ensinado nem em escolas de ensino fundamental nem no ensino médio.

Resumo Define-se trombose induzida pelo calor endovenoso como a propagação do trombo a partir de uma veia superficial em direção a uma veia mais profunda. Em geral, é considerada clinicamente insignificante quando não há propagação do trombo para o sistema venoso profundo. Essa condição pode ser tratada com terapia anticoagulante, embora a observação pareça ser suficiente, principalmente para graus menores. Neste estudo, relatamos dois casos de trombose induzida pelo calor endovenoso que teriam indicação de heparina de baixo peso molecular até a resolução do quadro. Porém, optou-se pelo uso da rivaroxabana (15 mg de 12 em 12h), com resolução completa do trombo em 4 semanas (caso 1) e em 7 dias (caso 2). A rivaroxabana pode ser uma alternativa promissora no tratamento da trombose induzida pelo calor endovenoso avançada, pela simplicidade da posologia, sem comprometimento da eficácia ou da segurança. São necessários estudos prospectivos, randomizados e controlados que possibilitem melhor entendimento da condição e o desenvolvimento de recomendações mais definitivas sobre opções de prevenção e tratamento.

To assess whether the spontaneous breathing test can predict the extubation failure in pediatric population. A prospective and observational study that evaluated data of inpatients at the Pediatric Intensive Care Unit between May 2011 and August 2013, receiving mechanical ventilation for at least 24 hours followed by extubation. The patients were classified in two groups: Test Group, with patients extubated after spontaneous breathing test, and Control Group, with patients extubated without spontaneous breathing test. A total of 95 children were enrolled in the study, 71 in the Test Group and 24 in the Control Group. A direct comparison was made between the two groups regarding sex, age, mechanical ventilation time, indication to start mechanical ventilation and respiratory parameters before extubation in the Control Group, and before the spontaneous breathing test in the Test Group. There was no difference between the parameters evaluated. According to the analysis of probability of extubation failure between the two groups, the likelihood of extubation failure in the Control Group was 1,412 higher than in the Test Group, nevertheless, this range did not reach significance (p=0.706). This model was considered well-adjusted according to the Hosmer-Lemeshow test (p=0.758). The spontaneous breathing test was not able to predict the extubation failure in pediatric population.

Mitral valve regurgitation (MR), present in up to 74% of the patients with severe aortic stenosis (AS), can be a negative prognostic factor when moderate or severe. The outcome of MR after percutaneous transcatheter aortic valve implantation (TAVI) and predictors associated with that outcome have not been well established in the literature. To assess the outcome of primary MR in patients submitted to TAVI and to identify associated factors. Observational study of patients with symptomatic severe AS submitted to TAVI from January 2009 to April 2015 at two specialized centers. Echocardiographic outcome was assessed with data collected before and 1 year after TAVI. Of the 91 patients with MR submitted to TAVI and followed up for at least 12 months, 67 (73.6%) had minimum/mild MR before the procedure and 24 (26.4%) had moderate/severe MR. Of those with minimum/mild MR, 62 (92.5%) had no change in the MR grade (p < 0.001), while 5 (7.5%) showed worsening. Of those with moderate/severe MR, 8 (33.3%) maintained the same grade and 16 (66.7%) improved it (p = 0.076). Patients with moderate/severe MR who improved MR grade had lower EuroSCORE II (p = 0.023) and STS morbidity (p = 0.027) scores, as compared to those who maintained the MR grade. MR grades change after TAVI. This study suggests a trend towards improvement in moderate/severe MR after TAVI, which was associated with lower preoperative risk scores.

The Susac's syndrome is a rare disorder that was first described in 1979 and is characterized by a classic triad consisting in encephalopathy, visual impairment and sensorineural hearing loss. However, the etiology of the disease is still unclear. We report the case of a 29-year-old with ulcerative colitis treated with mercaptopurine, six months before to her admission started with personality changes attributed to symptoms of depression who subsequently present neurological symptoms characteristic of Susac's Syndrome. In the literature there is no clear association between inflammatory bowel disease and Susac's -syndrome, but this case is presented in order to emphasize the simultaneous presentation of these two diseases with a tendency to vasospasm and an autoimmune pathogenesis.

to estimate the prevalence of hypoalbuminemia in hospitalized elders, related to socio-demographic variables, nutritional status and length of stay. crosscutting study with 200 patients hospitalized in a large hospital in the South of Brazil during three months. Evaluations, lab tests and interviews through questionnaires were performed. the average albuminemia was 2,9 ± 0,5g/dL. Hypoalbuminemia was diagnosed in 173 subjects (87%) and was absent in 27 (13%) that have normal albuminemia (p=0,000). After six days of hospitalization, the prevalence of low levels grew significantly to 90% (p=0,002), average 2,7 ± 0,5g/dL. Using the Mini Nutritional Assessment, it was observed that 41 patients were malnourished and from those, 40 had hypoalbuminemia. the prevalence of hypoalbuminemia proved to be high, in approx. nine in ten elders, and the nutritional status and the length of stay proved to be related to the decrease of serum albumin levels. Thus, it is suggested that monitoring albumin levels should be done to evaluate the risk that the patient has to develop malnutrition and other complications during hospital stays. estimar a prevalência de hipoalbuminemia em idosos hospitalizados, em relação às variáveis sociodemográficas, estado nutricional e tempo de internação. estudo transversal, com 200 pacientes internados em hospital de grande porte do sul do Brasil, durante o período de três meses.

Bone metabolism disorder (BMD) and vascular dysfunction contribute to excess cardiovascular mortality observed in hemodialysis patients. Vascular dysfunction, a new marker of atherosclerosis, can play a role in this risk. Even though associated with higher mortality in the general population, such vascular evaluation in patients on hemodialysis has not been extensively studied. In this cross-sectional study, hemodialysis patients were submitted to flow-mediated dilation, subendocardial viability ratio (SEVR) and ejection duration index assessment, in order to estimate the impact of BMD markers on vascular dysfunction. A matched cohort of patients with (n = 16) and without (n = 11) severe secondary hyperparathyroidism (SHPT) was studied. Additionally, time spent under severe SHPT was also evaluated. Patients with severe SHPT had lower SEVR and higher ejection duration index, indicating higher cardiovascular risk. Lower SEVR was also associated to diastolic blood pressure (r = 0.435, p = 0.049), serum 25-Vitamin-D levels (r = 0.479, p = 0.028) and to more time spent under severe secondary hyperparathyroidism (SHPT), defined as time from PTH > 500pg/ml until parathyroidectomy surgery or end of the study (r = -0.642, p = 0.027). In stepwise multiple regression analysis between SEVR and independent variables, lower SEVR was independently associated to lower serum 25-Vitamin-D levels (p = 0.005), female sex (p = 0.012) and more time spent under severe SHPT (p = 0.001) in a model adjusted for age, serum cholesterol, and blood pressure (adjusted r² = 0.545, p = 0.001). Subendocardial perfusion was lower in patients with BMD, reflecting higher cardiovascular risk in this population. Whether early parathyroidectomy in the course of kidney disease could modify such results still deserves further investigation. Distúrbios do metabolismo ósseo (DMO) e alterações da função vascular contribuem para a elevada mortalidade de pacientes em hemodiálise. A disfunção vascular

The variables included: age, sex, origin, signs and symptoms, exams, personal antecedents, classification in risk categories, medical specialties, and outcome. The Chi-square and likelihood ratio tests were used to associate classifications in risk categories with origin, signs and symptoms, exams, personal antecedents, medical specialty, and outcome. most patients were women with an average age of 44.5 years. Pain and dyspnea were the symptoms most frequently reported while hypertension and diabetes mellitus were the most common comorbidities. Classifications in the green and yellow categories were the most frequent and hospital discharge the most common outcome. Patients classified in the red category presented the highest percentage of ambulance origin due to surgical reasons. Those classified in the orange and red categories also presented the highest percentage of hospitalization and death. correlation between clinical aspects and outcomes indicate there is a relationship between the complexity of components in the categories with greater severity, evidenced by the highest percentage of hospitalization and death. correlacionar as categorias de classificação de risco com perfil clínico, desfechos e procedência. estudo transversal analítico realizado com 697 fichas de atendimento de pacientes adultos.

The estimation of workload in Intensive Care Units (ICUs) was performed using the Therapeutic Interventions Scoring System (TISS-28) and for the other services, we used the nurse/patient and nursing assistant/patient ratios. Descriptive univariate and multivariate analysis were performed. For the multivariate analysis we used principal component analysis and Pearson correlation. 879 post-discharge clinical records and the workload of 85 nurses and 157 nursing assistants were analyzed. The overall incident rate was 71.1%. It was found a high positive correlation between variables workload (r = 0.9611 to r = 0.9919) and rate of falls (r = 0.8770). The medication error rates, mechanical containment incidents and self-removal of invasive devices were not correlated with the workload. the workload was high in all units except the intermediate care unit. Only the rate of falls was associated with the workload. identificar a relação entre a carga de trabalho da equipe de enfermagem e a ocorrência de incidentes de segurança dos pacientes ligados aos cuidados de enfermagem de um hospital público no Chile. pesquisa transversal analítica quantitativa através de revisão de prontuários médicos.

ísico na doença arterial coronária, mas a predição de mortalidade e de eventos cardíacos maiores, em pacientes com teste ergométrico positivo para isquemia miocárdica, é limitada. Objetivo: Avaliar a predição de mortalidade e de eventos cardíacos maiores pela ecocardiografia com estresse físico em pacientes com teste ergométrico positivo para isquemia miocárdica. Métodos: Trata-se de uma coorte retrospectiva em que foram estudados 866 pacientes consecutivos, com teste ergométrico positivo para isquemia miocárdica, submetidos à ecocardiografia com estresse físico. Os pacientes foram divididos em dois grupos: ecocardiografia com estresse físico negativa (G1) ou positiva (G2) para isquemia miocárdica. Os desfechos avaliados foram mortalidade por qualquer causa e eventos cardíacos maiores, definidos como óbito cardíaco e infarto agudo do miocárdio não fatal. Resultados: O G2 constituiu-se de 205 (23,7%) pacientes. Durante o seguimento médio de 85,6 ± 15,0 meses, ocorreram 26 óbitos, sendo seis por causa cardíaca, e 25 casos de infarto agudo do miocárdio não fatais. Os preditores independentes de mortalidade foram idade, diabetes melito e a ecocardiografia com estresse físico + (hazard ratio: 2,69; intervalo de confiança de 95%: 1,20 - 6,01; p = 0,016), com os seguintes eventos cardíacos maiores: idade, doença arterial coronária prévia, ecocardiografia com estresse físico + (hazard ratio: 2,75; intervalo de confiança de 95%: 1,15 - 6,53; p = 0,022) e ausência do incremento de 10% na fração de ejeção. A mortalidade por qualquer causa e os eventos cardíacos maiores foram significativamente superiores no G2 (p < 0, 001 e p = 0,001, respectivamente). Conclusão: A ecocardiografia com estresse físico oferece informações prognósticas adicionais em pacientes com teste ergométrico positivo para isquemia miocárdica.

A probabilistic, simple random sample composed of 67 records of patients with Parkinson's disease who participated in a rehabilitation program, between March of 2009 and April of 2013. The research was conducted in three stages, in which the nursing terms were mapped to natural language and crossed with the Nursing Interventions Classification. a total of 1,077 standard interventions that, after crossing with the taxonomy and refinement performed by the experts, resulted in 32 interventions equivalent to the Nursing Interventions Classification (NIC) system. The NICs, "Education: The process of the disease.", "Contract with the patient", and "Facilitation of Learning" were present in 100% of the records. For these interventions, 40 activities were described, representing 13 activities by intervention. the cross mapping allowed for the identification of corresponding terms with the nursing interventions used every day in rehabilitation nursing, and compared them to the Nursing Interventions Classification. realizar o mapeamento cruzado de termos da linguagem de Enfermagem, com o sistema de Classificação das Intervenções de Enfermagem, em prontuários de pacientes com doença de Parkinson em reabilitação. estudo de pesquisa documental, para realização de mapeamento cruzado.

Analyzing the relationship between social support, quality of life and depression in patients eligible for palliative care at Primary Health Care of a municipality in the interior of Minas Gerais, Brazil. A correlational cross-sectional study carried out with patients treated in six primary health care units. Data were submitted to descriptive statistical analysis, tests for differences between averages and medians, and correlation tests. The significance level was 0.05. The sample consisted of 115 participants, and it was identified that the higher the social support, the better the global quality of life (p<0.001) and functional quality of life (p=0.035); the greater the presence of physical symptoms, the lower the level of social support (p=0.012) and the higher the level of depression (p<0.001); the higher the symptoms of depression, the worse the global quality of life (p<0.001), functional quality of life (p<0.001) and the lower the levels of social support (p<0.001). Levels of quality of life, social support and depression of patients eligible for palliative care are influenced by socioeconomic factors such as marital status, gender, age, income, education and presence of a caregiver.

To socialize an educational action through the process of group discussion and reflection, with the aim to increase the care of nursing workers in facing occupational risks. A qualitative descriptive study using the Convergent Care Research modality with nursing staff working in an emergency department of a hospital in the northwest region of the state of Rio Grande do Sul, Brazil. Data collection was carried out through educational workshops and information was processed using content analysis, resulting in two thematic categories: A look at the knowledge and practices about occupational risks in nursing; and adherence to protective measures by the nursing team against occupational risks. Twenty-four (24) workers participated in the study. When challenged to critically look at their actions, the subjects found that they relate the use of safety devices to situations in which they are aware of the patient's serological status. Subjects' interaction, involvement and co-responsibility in the health education process were determinant for their reflection on risky practices.

This text main objective is to discuss development and health from the perspective of the influence of global health governance, using as the tracer the dimension of research, development, and innovation policies in health, which relate to both important inputs for the health system, like drugs and medicines, vaccines, diagnostic reagents, and equipment, and innovative concepts and practices for the improvement of health systems and public health. The authors examine the two main macro-processes that influence development and health: the post-2015 Development Agenda and the process under way in the World Health Organization concerning research and development, intellectual property, and access to health inputs. The article concludes, first, that much remains to be done for the Agenda to truly represent a coherent and viable international political pact, and that the two macro-processes related to innovation in health need to be streamlined. But this requires democratization of participation by the main stakeholders - patients and the general population of the poorest countries - since this is the only way to overcome a "zero sum" result in the clash in the current debates among member State representatives. Resumo: O objetivo central deste texto é discutir desenvolvimento e saúde sob a ótica da influência da governança da saúde global, utilizando como traçador a dimensão das políticas de pesquisa, desenvolvimento e inovação em saúde, que se referem, de um lado, a insumos importantes para o sistema de saúde - como fármacos e medicamentos, vacinas, reativos para diagnóstico e equipamentos e, de outro, a conceitos e práticas inovadoras para o aperfeiçoamento dos sistemas de saúde e da saúde pública. Examina os dois principais macroprocessos que influenciam o desenvolvimento e a saúde: a Agenda do Desenvolvimento para o pós-2015 e o processo sobre pesquisa e desenvolvimento, propriedade intelectual e acesso a insumos em saúde em curso na Organiza

Analyzing statements of health professionals from a Street Clinic regarding care of a homeless population with tuberculosis. This is a qualitative research, conducted in the central region of São Paulo at three basic health units in the period of November to December 2014. A semi-structured interview guideline was implemented for data collection and all interviews were recorded using a digital recorder. Six health professionals were interviewed. According to the Discourse Analysis perspective, three discursive segments emerged: experiences on care in the streets; weaknesses inherent to the treatment process; and incentives as a means of maintaining sick people in treatment. Caring for a the homeless population with tuberculosis constitutes a new and challenging experience. It involves difficulties in dealing with the reality of a miserable social context, a lack and inadequacy of services, as well as care limitations for treatment and treatment dropout, which reinforces multiresistance. However, the investigated Street Clinic teams seek to expand access to health and social care services to this population. Analisar os discursos dos profissionais de saúde do Consultório na Rua em relação ao cuidado à pessoa em situação de rua com tuberculose. Trata-se de uma pesquisa qualitativa, realizada na região central do município de São Paulo, em três Unidades Básicas de Saúde, no período de novembro a dezembro de 2014. Utilizou-se de um roteiro de entrevista semiestruturada para a coleta de dados e todas as entrevistas foram gravadas com recurso a um gravador digital. Foram entrevistados seis profissionais de saúde. Segundo a perspectiva da Análise de Discurso, emergiram três blocos discursivos: experiência sobre o cuidar na rua; fragilidades inerentes ao processo de tratamento e incentivos como meio para a permanência do sujeito doente no tratamento.

Introducción y objetivos: el cobre (Cu) es un oligoelemento muy estudiado, pero poco se sabe de su evolución en los pacientes alimentados por gastrostomía endoscópica (GEP). Pretendemos evaluar la evolución del Cu sérico desde la gastrostomía hasta 12 semanas después de la intervención en estos pacientes alimentados con preparaciones domésticas.  Métodos: realizamos un estudio observacional prospectivo para evaluar el Cu sérico, la albúmina, la transferrina y el índice de masa corporal (IMC) en el momento de la GEP, tras 4 semanas y 12 semanas después de la intervención. Los datos incluyen edad, género, NRS 2002 y enfermedad subyacente: cánceres de cabeza y cuello (CCC) y disfagia neurológica (DN). Después de la intervención, estos pacientes fueron alimentados conpreparaciones domésticas. Resultados: 146 enfermos (89 hombres), entre 21-95 años: CCC-56, DN-90. Valores de Cu entre 42-160 μg/dl (normal: 70-140 μg/dl); normales 89% (n = 130); bajos 11% (n = 16), albúmina baja: 53% (n = 77), transferrina baja: 65% (n = 94), IMC bajo: 53% (n = 78). Después de 4 semanas: valores normales de Cu en 93% y bajos en 7%, albúmina baja en 34%, transferrina baja en 52%. Tras 12 semanas: valores normales de Cu en 95% y bajos en 5%, albúmina baja en 25%, transferrina baja en 32%. No encontramos diferencias significativas en el Cusérico cuando se compara edad, género, enfermedad subyacente, IMC, albúmina y transferrina. Conclusiones: la mayoría de los enfermos presentan Cu sérico normal en el momento de la gastrostomía. Para los enfermos con Cu sérico bajo antes del procedimiento, la alimentación con preparaciones domésticas parece suficiente para su normalización progresiva.

En la actualidad existe una alta variabilidad en la práctica clínica en nutrición que podría afectar al estado nutricional de los pacientes oncológicos. La implementación de guías de práctica clínica de adecuada calidad puede ayudarnos a disminuir esta variabilidad y minimizar los efectos deletéreos de la malnutrición en los pacientes oncológicos. Las guías suelen estar basadas en la evidencia, formulando las recomendaciones a partir de la mejor información disponible. No obstante, es importante tener en cuenta la calidad metodológica en la elaboración de las guías y valorar si existen conflictos de interés. Los principales problemas de las guías actuales suelen ser que existe limitada evidencia de alta calidad, y que las recomendaciones basadas exclusivamente en la evidencia pueden no ser útiles en la práctica clínica diaria, ya que no tienen en cuenta la aplicabilidad que es fundamental para su implementación. Por otro lado, las guías clínicas hasta la actualidad han sido inconsistentes en la forma de evaluar la calidad de la evidencia y el grado de recomendación. Como resultado, los usuarios se enfrentan al desafío de comprender los mensajes que los diferentes sistemas de grados de evidencia tratan de comunicar. En esta revisión se realiza un resumen de las recomendaciones de las principales guías clínicas sobre valoración y/o soporte nutricional en pacientes oncohematológicos desarrolladas en los últimos 10 años, incluyendo algunas guías de calidad de sociedades científicas que no son accesibles a través de las bases de datos comúnmente usadas como PubMed.

Introducción: La cirugía de los trastornos del comportamiento (CTC) se está convirtiendo en un tratamiento más común desde el desarrollo de la neuromodulación. Métodos: Este artículo es una revisión no sistemática de la historia, indicaciones actuales, técnicas y blancos quirúrgicos de la CTC. Dividimos su historia en 3 eras: la primera comienza en los inicios de la psicocirugía y termina con el desarrollo de las tícnicas estereotácticas, cuando comienza la segunda era. Ésta se caracteriza por la realización de lesiones estereotácticas. Nos encontramos transitando la tercera era, que comienza cuando la estimulación cerebral profunda (ECP) comienza a ser usada en CTC. Resultados: A pesar de los errores graves cometidos en el pasado, hoy en día, la CTC está renaciendo. Los trastornos psiquiátricos que se más frecuentemente se tratan con cirugía son: depresión refractaria, trastorno obsesivo-compulsivo y síndrome de Tourette. Además, algunos pacientes con agresividad fueron tratados quirúrgicamente. Hay varios blancos estereotácticos descriptos para estos trastornos. La estimulación vagal puede ser usada también para depresión. Conclusión: Los resultados de la ECP en estos trastornos parecen alentadores. Sin embargo, se necesitan más estudios randomizados para establecer la efectividad de la CTC. Debe tenerse en cuenta que una apropiada selección de pacientes nos ayudará a realizar un procedimiento más seguro así como también a lograr mejores resultados quirúrgicos, conduciendo a la CTC a ser más aceptada por psiquiatras, pacientes y sus familias. Se necesita mayor investigación en varios temas como: fisiopatología de los trastornos del comportamiento, indicaciones de CTC y nuevos blancos quirúrgicos. PMID:25165612

Introducción: la esofagitis eosinofílica (EEo) es una enfermedad inmunoalérgica crónica emergente en adultos. Surge como respuesta disfuncional frente a los antígenos de los alimentos y se caracteriza por síntomas recurrentes de disfunción esofágica e inflamación. El tratamiento farmacológico y dietético se basa en su patogénesis y debe ser individualizado. Uno de los posibles abordajes dietéticos se basa en la eliminación empírica de alimentos que con mayor frecuencia causan EEo.Objetivo: evaluar la ingesta dietética de los pacientes con EEo que siguen la dieta de exclusión de los seis grupos de alimentos (DESGA) y conocer sus posibles carencias nutricionales.Métodos: estudio transversal descriptivo en un grupo de pacientes con EEo que inició tratamiento con DESGA durante el periodo de marzo de 2013 hasta marzo de 2015. Se evaluó la ingesta mediante registro de 72 horas. Se compararon los resultados con las referencias para población adulta sana española (23). Para el análisis estadístico se usaron los test de Mann-Whitney, Krhuskall-Wallis y Chi-cuadrado. Significación p < 0,05.Resultados: se incluyeron en el estudio 14 pacientes. En algunos de ellos, la ingesta dietética siguiendo DESGA fue deficitaria en energía, proteínas y fibra. Tampoco consiguieron cubrir las ingestas de micronutrientes de calcio, zinc, magnesio, ácido fólico, niacina y vitaminas B2 y D, teniendo en cuenta edad y sexo, el 60% de la muestra.Conclusiones: el abordaje terapéutico mediante DESGA, teniendo en cuenta las características de la dieta, debe acompañarse de una evaluación periódica del estado nutricional, que incluya micronutrientes y una pauta de suplementación específica.

To identify the presence of phlebitis and the factors that influence the development of this complication in adult patients admitted to hospital in the western Brazilian Amazon. Exploratory study with a sample of 122 peripheral intravenous catheters inserted in 122 patients in a medical unit. Variables related to the patient and intravenous therapy were analyzed. For the analysis, we used chi-square tests of Pearson and Fisher exact test, with 5% significance level. Complication was the main reason for catheter removal (67.2%), phlebitis was the most frequent complication (31.1%). The mean duration of intravenous therapy use was 8.81 days in continuous and intermittent infusion (61.5%), in 20G catheter (39.3%), inserted in the dorsal hand vein arc (36.9 %), with mean time of usage of 68.4 hours. The type of infusion (p=0.044) and the presence of chronic disease (p=0.005) and infection (p=0.007) affected the development of phlebitis. There was a high frequency of phlebitis in the sample, being influenced by concomitant use of continuous and intermittent infusion of drugs and solutions, and more frequent in patients with chronic diseases and infection.

Fuzheng Huayu recipe (FZHY) is formulated on the basis of Chinese medicine theory in treating liver fibrosis. To illuminate the influence of the pathological state of liver fibrosis on the pharmacokinetics and tissue distribution profiles of lignan components from FZHY. Male Wistar rats were randomly divided into normal group and Hepatic fibrosis group (induced by dimethylnitrosamine). Six lignan components were detected and quantified by ultrahigh performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS)in the plasma and tissue of normal and hepatic fibrosis rats. A rapid, sensitive and convenient UHPLC-MS/MS method has been developed for the simultaneous determination of six lignan components in different rat biological samples successfully. After oral administration of FZHY at a dose of 15g/kg, the pharmacokinetic behaviors of schizandrin A (SIA), schizandrin B (SIB), schizandrin C (SIC), schisandrol A (SOA), Schisandrol B (SOB) and schisantherin A (STA) have been significantly changed in hepatic fibrosis rats compared with the normal rats, and their AUC(0-t) values were increased by 235.09%, 388.44%, 223.30%, 669.30%, 295.08% and 267.63% orderly (P<0.05). Tissue distribution results showed the amount of SIA, SIB, SOA and SOB were significant increased in heart, lung, spleen and kidney of hepatic fibrosis rats compared with normal rats at most of the time point (P<0.05). Meanwhile, the result also reveals that the hepatic fibrosis could delay the peak time of lignans in liver. The results proved that the established UHPLC-MS/MS method could be applied to the comparative study on pharmacokinetics and tissue distribution of lignan components in normal and hepatic fibrosis rats. The hepatic fibrosis could alter the pharmacokinetics and tissue distribution properties of lignan components in rats after administration of FZHY. The results might be helpful for guide the clinical application of this medicine. Copyright © 2015 Elsevier Ireland Ltd. All

Reflect on the essence of care in health vulnerability from the phenomenological perspective of Martin Heidegger. Theoretical-reflexive study, anchored in three essential parts: 1) Care in Heidegger; 2) The essence of care in health vulnerability; And 3) Nursing care actions on health vulnerability. Vulnerability must be recognized as an indelible trait of the human condition and has its constituents in the human being, co-presence and care. Caring is an interactive process that reveals itself in the relationship with the other. Respecting the integrity of the Being in vulnerability must be a priority in nursing care, through behaviors that privilege the Being. Understanding ontological care and its relation to vulnerability under Heidegger's phenomenological view allowed us to uncover the facets of care in health vulnerability by adding to the nursing knowledge body a comprehensive and reflective perspective. Refletir sobre a essência do cuidado na vulnerabilidade em saúde sob a perspectiva fenomenológica de Martin Heidegger. Estudo teórico-reflexivo, ancorado em três partes essenciais: 1) O cuidado em Heidegger; 2) A essência do cuidado na vulnerabilidade em saúde; e 3) As ações do cuidar em enfermagem na vulnerabilidade em saúde. A vulnerabilidade deve ser reconhecida como traço indelével da condição humana e tem seus constituintes na pessoa humana, co-presenças e cuidado. O cuidar é um processo interativo que se desvela na relação com o outro. Respeitar a integridade do Ser em vulnerabilidade deve ser prioridade no cuidar em enfermagem, por meio de comportamentos que privilegiem o Ser. Compreender ontologicamente o cuidado e a sua relação com a vulnerabilidade sob o olhar fenomenológico de Heidegger permitiu desvelar as facetas do cuidado na vulnerabilidade em saúde, agregando ao corpo de conhecimento da Enfermagem uma perspectiva compreensiva e reflexiva.

Denitrifying sulfur conversion-associated EBPR: The effect of pH on anaerobic metabolism and performance.

The performance of the denitrifying sulfur conversion-associated enhanced biological phosphorus removal (DS-EBPR) process tends to be unstable and requires further study and development. This in turn requires extensive study of the anaerobic metabolism in terms of its stoichiometry and kinetics. This study evaluates the corresponding responses of DS-EBPR to pH, as it significantly influences both stoichiometry and biochemical kinetics. The impacts of five representative pH values ranging between 6.5 and 8.5 on the anaerobic metabolism were investigated, followed by identification of the optimal pH for performance optimization. A mature DS-EBPR sludge was used in the study, enriched with approximately 30% sulfate-reducing bacteria (SRB) and 33% sulfide-oxidizing bacteria (SOB). Through a series of batch tests, the optimal pH range was determined as 7.0-7.5. In this pH range, the anaerobic stoichiometry of phosphorus released/volatile fatty acid (VFA) uptake ratio, sulfate reduction, and internal polymer production (including poly-β-hydroxyalkanoates and polysulfide and/or elemental sulfur) all increased along with the anaerobic kinetics of the VFA uptake ratio. Consequently, phosphorus removal was maximized at this pH range (≥95% vs. 84-93% at other pH values), as was sulfur conversion (16 mg S/L vs. 10-13 mg S/L). This pH range therefore favors the activity and synergy of the key functional bacteria (i.e. SRB and SOB). Anaerobic maintenance tests showed these bacteria required 38-61% less energy for maintenance than that reported for GAOs regardless of pH changes, improving their ability to cope with anaerobic starvation. Adversely, both bacteria showed much lower VFA uptake rates than that of GAOs at all tested pH values (0.03-0.06 vs. 0.2-0.24 mol-C/C-mol biomass/h), possibly revealing the primary cause of frequent instability in the DS-EBPR process.

Nitrate decreases sulfide release in wastewater treatment plants (WWTP), but little is known on how it affects the microzonation and kinetics of related microbial processes within the biofilm. The effect of nitrate addition on these properties for sulfate reduction, sulfide oxidation, and oxygen respiration were studied with the use of microelectrodes in microaerophilic wastewater biofilms. Mass balance calaculations and community composition analysis were also performed. At basal WWTP conditions, the biofilm presented a double-layer system. The upper microaerophilic layer (~300 μm) showed low sulfide production (0.31 μmol cm-3 h-1) and oxygen consumption rates (0.01 μmol cm-3 h-1). The anoxic lower layer showed high sulfide production (2.7 μmol cm-3 h-1). Nitrate addition decreased net sulfide production rates, caused by an increase in sulfide oxidation rates (SOR) in the upper layer, rather than an inhibition of sulfate reducing bacteria (SRB). This suggests that the indigenous nitrate reducing-sulfide oxidizing bacteria (NR-SOB) were immediately activated by nitrate. The functional vertical structure of the biofilm changed to a triple-layer system, where the previously upper sulfide-producing layer in the absence of nitrate split into two new layers: 1) an upper sulfide-consuming layer, whose thickness is probably determined by the nitrate penetration depth within the biofilm, and 2) a middle layer producing sulfide at an even higher rate than in the absence of nitrate in some cases. Below these layers, the lower net sulfide-producing layer remained unaffected. Net SOR varied from 0.05 to 0.72 μmol cm-3 h-1 depending on nitrate and sulfate availability. Addition of low nitrate concentrations likely increased sulfate availability within the biofilm and resulted in an increase of both net sulfate reduction and net sulfide oxidation by overcoming sulfate diffusional limitation from the water phase and the strong coupling between SRB and NR-SOB syntrophic

Why eating star fruit is prohibited for patients with chronic kidney disease?

New studies have shown the mechanism by which the star fruit (Averrhoa carambola) becomes toxic to individuals with chronic kidney disease (CKD). The aim of this study was to review the current literature on the topic. This is a review article, with publications from 2000 to 2014 available in scientific database. There are reports that neurotoxicity is due to the presence of oxalate in star fruit, but recent findings show that the neurotoxic effect of the toxin is by caramboxin, which appears to inhibit the GABAergic system which is the major inhibitory system in the central nervous system (CNS), involving changes as sobs and confusion, to more serious conditions such as seizures and death. It is important to multidisciplinary action to alert patients with CKD as the prohibition of the star fruit consumption.

Health literacy in patients attending a University Hospital. Low level of health literacy is associated with poor communication between patients and clinicians and with increased hospitalization rates, less frequent screening for cancer, poor control of diabetes, and disproportionately high rates of disease and mortality. Despite the importance of health literacy in medicine, there is no information about its prevalence in Latin America. The aim of this study was to assess the prevalence of inadequate health literacy in a random sample of patients, at a University Hospital where a descriptive study was performed during 2007. Health literacy was assessed through the Short Assessment of Health Literacy for Spanish-speaking Adults. Participants were randomly selected from the ambulatory clinic and from the medical inpatient ward during 2007.There were a total of 2345 patients potentially eligible during the time of the study, 234 were approached after random selection and 229 patients were interviewed (98% response); 54.6% of respondents were women and 62% were recruited from the ambulatory clinic. The respondents had a median age of 56 years. The prevalence of inadequate health literacy was 30.1% (69 patients). Patients with ≤ 7 years of formal education had more risk of having inadequate health literacy compared with those with > 12 years of education OR = 45.1 (IC 9.6-211.6). We found a high prevalence of inadequate health literacy, being strongly associated with the level of formal education. It is important that health care providers know the implications of health literacy and its consequences. PMID:20053602

Data were collected using In-hospital Utstein Style. The control group (n=60) was selected by matching patients considering their neurological condition before cardiac arrest, the immediate cause, initial arrest rhythm, whether epinephrine was used, and the duration of CPR. The case group (n=51) received conventional CPR guided by a metronome set at 110 beats/min. Chi-square and likelihood ratio were used to compare ROSC rates considering p≤0.05. ROSC occurred in 57.7% of the cases, though 92.8% of these patients died in the following 24 hours. No statistically significant difference was found between groups in regard to ROSC (p=0.2017) or the occurrence of death (p=0.8112). the outcomes of patients after cardiac arrest with and without the use of a metronome during CPR were similar and no differences were found between groups in regard to survival rates and ROSC. comparar a taxa de retorno da circulação espontânea e óbito após parada cardiorrespiratória, com e sem a utilização do metrônomo durante ressuscitação cardiopulmonar. estudo caso-controle aninhado a estudo de coorte, com 285 adultos atendidos em parada cardíaca em um serviço de emergência e submetidos à ressuscitação cardiopulmonar.

Death was more common in females and those of black skin color, with a mean age of 65 years. Acute myocardial infarction was the most common hospitalization diagnosis. The majority of the complications recorded during hospitalization were characterized by changes in the cardiovascular system, with longer hospitalization periods being directly related to death from septic shock. the data provide subsidies for nursing work with preventive measures and early detection of complications associated with coronary artery bypass grafting. This reinforces the importance of using the data as quality indicators, aiming to guarantee care guided by reliable information to guide managers in planning patient care and high complexity health services. conhecer os fatores associados à mortalidade de pacientes submetidos à cirurgia de revascularização do miocárdio em hospital referência cardiovascular em Santa Catarina. estudo quantitativo, exploratório, descritivo e retrospectivo.

to build and validate a scale to assess the risk of surgical positioning injuries in adult patients. methodological research, conducted in two phases: construction and face and content validation of the scale and field research, involving 115 patients. the Risk Assessment Scale for the Development of Injuries due to Surgical Positioning contains seven items, each of which presents five subitems. The scale score ranges between seven and 35 points in which, the higher the score, the higher the patient's risk. The Content Validity Index of the scale corresponded to 0.88. The application of Student's t-test for equality of means revealed the concurrent criterion validity between the scores on the Braden scale and the constructed scale. To assess the predictive criterion validity, the association was tested between the presence of pain deriving from surgical positioning and the development of pressure ulcer, using the score on the Risk Assessment Scale for the Development of Injuries due to Surgical Positioning (p<0.001). The interrater reliability was verified using the intraclass correlation coefficient, equal to 0.99 (p<0.001). the scale is a valid and reliable tool, but further research is needed to assess its use in clinical practice. construir e validar escala de avaliação de risco para lesões decorrentes do posicionamento cirúrgico em pacientes adultos. pesquisa metodológica, conduzida em duas etapas: construção e validação de face e de conteúdo da escala e pesquisa de campo, com a participação de 115 pacientes. a Escala de Avaliação de Risco para o Desenvolvimento de Lesões Decorrentes do Posicionamento Cirúrgico contém sete itens, sendo que cada um apresenta cinco subitens.

Através de simulações numéricas buscamos quantificar os efeitos que o binarismo não resolvido causa na determinação da função de massa (MF) de aglomerados estelares. Geramos diagramas cor-magnitude (CMDs) artificiais simulando uma população única, caracterizada por estrelas de mesma idade e composição quí mica, com uma fração de binárias não resolvidas e distribuição em massa das estrelas dada por uma MF do tipo lei de potência. A presença de pares de estrelas não resolvidos faz com que a MF obtida da função de luminosidade (LF) tenha a têndencia de ser mais plana do que a MF que gerou o CMD artificial. Propomos um tratamento de correção para tal efeito. Outro efeito relacionado diz respeito ao alargamento do CMD, que apresenta-se como um indicador do número total de estrelas no domí nio de baixas massas (m < 0.6M¤). Todos os resultados acima possuem uma forte dependência com os erros fotométricos e estão baseados na hipótese de que ambas estrelas do par não resolvido são sorteadas de uma mesma MF de forma independente. O objetivo final é aplicarmos o tratamento aqui desenvolvido para implementarmos a análise da nossa amostra de aglomerados ricos da Grande Nuvem de Magalhães.

There is no consensus on the ideal size of intestinal loops in gastric bypass of bariatric surgeries. To evaluate the metabolic outcome of patients submitted to gastric bypass with alimentary and biliopancreatic loops of different sizes. Was conducted a retrospective cohort study in diabetic obese patients (BMI≥35 kg/m2) with metabolic syndrome submitted to gastric bypass. The patients were divided into three groups according to the size of the intestinal loop: group 1, biliopancreatic limb 50 cm length and alimentary limb 100 cm length; group 2 , biliopancreatic limb 50 cm length and alimentary limb 150 cm length; and group 3, biliopancreatic limb 100 cm length and alimentary limb 150 cm length. The effect of gastric bypass with different sizes of intestinal loops in relation to the parameters that define metabolic syndrome was determined. Sixty-three patients were evaluated, and they had a mean age of 44.7±9.4 years. All were diabetics, with 62 (98.4%) being hypertensive and 51 (82.2%) dyslipidemic. The three groups were homogeneous in relation to the variables. In 24 months, there was a remission of systemic arterial hypertension in 65% of patients in group 1, 62.5% in group 2 and 68.4% in group 3. Remission of diabetes occurred in 85% of patients in group 1, 83% in group 2 and 84% in group 3. There was no statistical difference in %LEW between the groups, and waist measurements decreased in a homogeneous way in all groups. The size of loops also had no influence on the improvement in dyslipidemia. Variation in size of intestinal loops does not appear to influence improvement in metabolic syndrome in this group of patients.

To evaluate the influence of chronic heart failure (CHF) on resting lung volumes in patients with COPD, i.e., inspiratory fraction-inspiratory capacity (IC)/TLC-and relative inspiratory reserve-[1 - (end-inspiratory lung volume/TLC)]. This was a prospective study involving 56 patients with COPD-24 (23 males/1 female) with COPD+CHF and 32 (28 males/4 females) with COPD only-who, after careful clinical stabilization, underwent spirometry (with forced and slow maneuvers) and whole-body plethysmography. Although FEV1, as well as the FEV1/FVC and FEV1/slow vital capacity ratios, were higher in the COPD+CHF group than in the COPD group, all major "static" volumes-RV, functional residual capacity (FRC), and TLC-were lower in the former group (p < 0.05). There was a greater reduction in FRC than in RV, resulting in the expiratory reserve volume being lower in the COPD+CHF group than in the COPD group. There were relatively proportional reductions in FRC and TLC in the two groups; therefore, IC was also comparable. Consequently, the inspiratory fraction was higher in the COPD+CHF group than in the COPD group (0.42 ± 0.10 vs. 0.36 ± 0.10; p < 0.05). Although the tidal volume/IC ratio was higher in the COPD+CHF group, the relative inspiratory reserve was remarkably similar between the two groups (0.35 ± 0.09 vs. 0.44 ± 0.14; p < 0.05). Despite the restrictive effects of CHF, patients with COPD+CHF have relatively higher inspiratory limits (a greater inspiratory fraction). However, those patients use only a part of those limits, probably in order to avoid critical reductions in inspiratory reserve and increases in elastic recoil.

To determine the presence of staphylococcal superantigen-specific IgE antibodies and degree of IgE-mediated sensitization, as well as whether or not those are associated with the severity of asthma in adult patients. This was a cross-sectional study involving outpatients with asthma under treatment at a tertiary care university hospital in the city of Rio de Janeiro, Brazil. Consecutive patients were divided into two groups according to the severity of asthma based on the Global Initiative for Asthma criteria: mild asthma (MA), comprising patients with mild intermittent or persistent asthma; and moderate or severe asthma (MSA). We determined the serum levels of staphylococcal toxin-specific IgE antibodies, comparing the results and performing a statistical analysis. The study included 142 patients: 72 in the MA group (median age = 46 years; 59 females) and 70 in the MSA group (median age = 56 years; 60 females). In the sample as a whole, 62 patients (43.7%) presented positive results for staphylococcal toxin-specific IgE antibodies: staphylococcal enterotoxin A (SEA), in 29 (20.4%); SEB, in 35 (24.6%); SEC, in 33 (23.2%); and toxic shock syndrome toxin (TSST), in 45 (31.7%). The mean serum levels of IgE antibodies to SEA, SEB, SEC, and TSST were 0.96 U/L, 1.09 U/L, 1.21 U/L, and 1.18 U/L, respectively. There were no statistically significant differences between the two groups in terms of the qualitative or quantitative results. Serum IgE antibodies to SEA, SEB, SEC, and TSST were detected in 43.7% of the patients in our sample. However, neither the qualitative nor quantitative results showed a statistically significant association with the clinical severity of asthma.

Retrospectivamente foram analisados os prontuários médicos de 20.000 casos de operações bariátricas de janeiro 2002 a janeiro de 2016, procurando por ocorrência de má-rotação intestinal, sua interferência na técnica operatória aplicada e a evolução imediata no pós-operatório. Foram encontrados cinco casos (0.025%) de má-rotação intestinal em homens com idades de 37, 39, 45, 49 e 52 anos e IMC de 35, 42, 49, 47 e 52 kg/m2. O paciente com IMC de 35 kg/m2 também sofria de diabete melito tipo 2. Todos os procedimentos foram realizados através de laparoscopia, sem conversões. Em um paciente não foi possível mover o jejuno para o abdome superior a fim de realizar gastrojejunostomia; foi, então, realizada gastrectomia vertical. Em outro paciente, não foi possível reconhecer totalmente a anatomia devido às aderências intestinais e foi decidido realizar bypass gástrico com anastomose única. Nenhum vazamento ou sangramento foi identificado. Não houve nenhuma complicação pós-operatória. Todos os pacientes foram liberados 72 h após o procedimento e nenhuma complicação foi notificada nos primeiros 30 dias. A cirurgia bariátrica laparoscópica pode ser realizada com sucesso em pacientes com má-rotação. Mudanças talvez sejam necessárias com relação à anomalia. Os cirurgiões devem verificar toda a condição anatômica abdominal antes de iniciar a secção gástrica.

to evaluate the profile of skin cancer in Pomeranian communities of the State of Espírito Santo, composed of descendants of European immigrants, regarding gender and age at diagnosis, lesion size and histological type. we studied histopathological reports of 3,781 patients operated between 2000 and 2010, with resection of 4,881 lesions. We assessed histological type, lesion size, age and gender of the patients at diagnosis and their correlations in the 11-year period. the histopathological examination revealed basal cell carcinoma in 3,159 patients (83.5%), squamous cell carcinoma in 415 (11%), melanoma in 64 (1.7%), and 143 patients (3.8%) had combined lesions of basal cell carcinoma and squamous cell carcinoma. As to size, 47.1% measured between 5.1 and 10mm. The age group of 61 to 70 years was the one that sustained the largest number of surgical interventions (24.3%). There was a predominance of the female gender (2,027, 53.6%) in relation to the male (1,754, 46.4%). basal cell carcinoma was the most frequent histological type. The prevalences of squamous cell carcinoma and melanoma were below the national estimate of the National Cancer Institute. The diagnosis of tumors occurred at more advanced ages (above 60 years) and there was an increase in the incidence and size of skin tumors in the male population. avaliar o panorama do câncer de pele em comunidades pomeranas do Estado do Espírito Santo, compostas por descendentes de imigrantes europeus, quanto ao sexo e idade ao diagnóstico, tamanho da lesão e tipo histológico. foram avaliados laudos histopatológicos de 3781 pacientes operados entre os anos de 2000 e 2010, com ressecção de 4881 lesões.

To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein. Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies. In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients. Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others.

to determine the ED90 (minimum effective dose in 90% of patients) of sugammadex for the reversal of rocuronium-induced moderate neuromuscular blockade (NMB) in patients with grade III obesity undergoing bariatric surgery. we conducted a prospective study with the biased coin up-and-down sequential design. We chosen the following doses: 2.0mg/Kg, 2.2mg/Kg, 2.4mg/Kg, 2.6mg/Kg, 2.8mg/Kg. The complete reversal of rocuronium-induced NMB considered a T4/T1 ratio ≥0.9 as measured by TOF. After induction of general anesthesia and calibration of the peripheral nerve stimulator and accelerometer, we injected rocuronium 0.6mg/kg. We administered propofol and remifentanil by continuous infusion, and intermittent boluses of rocuronium throughout the procedure. we evaluated 31 patients, of whom 26 had displayed successful reversal of the NMB with sugammadex, and failure in five. The mean time to complete moderate NMB reversal was 213 seconds (172-300, median 25-75%). The ED90 of sugammadex calculated by regression was 2.39mg/kg, with a 95% confidence interval of 2.27-2.46 mg/kg. the ED90 of sugammadex in patients with grade III obesity or higher was 2.39mg/kg. determinar a ED90 (dose mínima eficaz em 90% dos pacientes) de sugamadex para a reversão de bloqueio neuromuscular (BNM) moderado induzido pelo rocurônio em pacientes com obesidade grau III submetidos à cirurgia bariátrica. estudo prospectivo com o método de projeção sequencial para cima e para baixo da moeda enviesada.

Resistance exercise (RE) has been recommended for patients with cardiovascular diseases. Recently, a few studies have demonstrated that the intensity of a single bout of RE has an effect on endothelial adaptations to exercise. However, there is no data about the effects of different volumes of RE on endothelium function. The aim of the study was to evaluate the effects of different volumes of RE in a single bout on endothelium-dependent vasodilatation and nitric oxide (NO) synthesis in the mesenteric artery of healthy animals. Male Wistar rats were divided into three groups: Control (Ct); low-volume RE (LV, 5 sets x 10 repetitions) and high-volume RE (HV, 15 sets x 10 repetitions). The established intensity was 70% of the maximal repetition test. After the exercise protocol, rings of mesenteric artery were used for assessment of vascular reactivity, and other mesenteric arteries were prepared for detection of measure NO production by DAF-FM fluorescence. Insulin responsiveness on NO synthesis was evaluated by stimulating the vascular rings with insulin (10 nM). The maximal relaxation response to insulin increased in the HV group only as compared with the Ct group. Moreover, the inhibition of nitric oxide synthesis (L-NAME) completely abolished the insulin-induced vasorelaxation in exercised rats. NO production showed a volume-dependent increase in the endothelial and smooth muscle layer. In endothelial layer, only Ct and LV groups showed a significant increase in NO synthesis when compared to their respective group under basal condition. On the other hand, in smooth muscle layer, NO fluorescence increased in all groups when compared to their respective group under basal condition. Our results suggest that a single bout of RE promotes vascular endothelium changes in a volume-dependent manner. The 15 sets x 10 repetitions exercise plan induced the greatest levels of NO synthesis. O exercício resistido (ER) tem sido recomendado para pacientes com doen

Introducción: la malnutrición en el anciano que ingresa en el hospital es bastante frecuente y condiciona no solo la extensión de la estancia hospitalaria, sino el pronóstico o la aparición de otras patologías. Su valoración puede basarse en medidas antropométricas, parámetros bioquímicosy test nutricionales.Objetivos: valorar si la circunferencia de pantorrilla es un indicador válido de desnutrición en el paciente anciano recién hospitalizado, analizando la posible influencia del sexo y la edad.Material y métodos: estudio descriptivo en 907 pacientes ancianos pluripatológicos a su ingreso en el hospital, con una edad media de 82,13 ± 7,08 años. Se han realizado determinaciones bioquímicas incluyendo recuento de linfocitos, colesterol total, transferrina y albúmina.Se aplicaron en cada paciente las escalas de cribado nutricional MNA, NRS y VGS. Finalmente se determinó la circunferencia de la pantorrilla.Resultados: los test nutricionales muestran un porcentaje de desnutrición medio del 75%. Los parámetros bioquímicos muestran un porcentaje de desnutrición que oscila del 63,4% al 76,7%, y la circunferencia de la pantorrilla un 74,2%. La prevalencia de desnutrición es mayor en mujeres, independientemente del parámetro utilizado en su determinación. El aumento en la edad, particularmente a partir de los 85 años, y con todos los parámetros analizados, también condiciona un mayor grado de desnutrición. Todos los parámetros estudiados se correlacionan con la circunferencia de la pantorrilla, estableciéndose el concepto "estar desnutrido" en el punto de corte de 29 cm, para ambos sexos y en todos los grupos de edad (sensibilidad 99,31%).Conclusiones: un 75% de la población anciana presenta desnutrición a su ingreso en el hospital. La circunferencia de la pantorrilla es un marcador de desnutrición en el anciano de fácil determinación y alta sensibilidad, independiente del sexo y la edad.

Resumen Introducción y objetivo: El TCE leve representa un problema sanitario de enorme interés debido a que un número significativo de enfermos con trauma leve desarrollará complicaciones potencialmente mortales. El objetivo de este estudio ha sido describir una serie amplia de pacientes adultos, mayores de 14 años, que sufren TCE leve, atendidos en el Hospital Universitario de Getafe, entre los años 2010 y 2015 (n = 2480), estudiar el perfil epidemiológico y analizar el diagnóstico y el tratamiento efectuados, así como establecer los principales factores pronósticos que influyen en el resultado final. Método: Se ha realizado un estudio retrospectivo, de revisión de historias clínicas, analizando los resultados con estudio estadístico bivariable y multivariable. Resultados: El TCE leve es más frecuente en varones, y el mecanismo causante más común en nuestro medio es el accidente de tráfico. Se propone un modelo de clasificación de pacientes según grupos de riesgo, que los subdivide en riesgo bajo, intermedio o alto, que se correlaciona bien con la probabilidad de desarrollar complicación intracraneal, y, consecuentemente, con el resultado final. Se discute la indicación de la radiografía simple de cráneo y de la Tomografía Computarizada (TC), así como del ingreso hospitalario para observación neurológica. Conclusiones: En este estudio, la presencia de focalidad neurológica en la exploración clínica, la edad, las alteraciones de la coagulación y la existencia de fractura en la radiografía simple se relacionan con mayor posibilidad de desarrollar lesiones traumáticas intracraneales y con peor pronóstico final. La escala de Glasgow para el Coma es deficitaria en la determinación del resultado final del paciente que sufre TCE, porque no considera variables tales como la amnesia o la pérdida de conocimiento, muy frecuentes en el traumatismo craneoencefálico leve.

Hepcidin: an important iron metabolism regulator in chronic kidney disease.

PubMed

Antunes, Sandra Azevedo; Canziani, Maria Eugênia Fernandes

2016-01-01

Anemia is a common complication and its impact on morbimortality in patients with chronic kidney disease (CKD) is well known. The discovery of hepcidin and its functions has contributed to a better understanding of iron metabolism disorders in CKD anemia. Hepcidin is a peptide mainly produced by hepatocytes and, through a connection with ferroportin, it regulates iron absorption in the duodenum and its release of stock cells. High hepcidin concentrations described in patients with CKD, especially in more advanced stages are attributed to decreased renal excretion and increased production. The elevation of hepcidin has been associated with infection, inflammation, atherosclerosis, insulin resistance and oxidative stress. Some strategies were tested to reduce the effects of hepcidin in patients with CKD, however more studies are necessary to assess the impact of its modulation in the management of anemia in this population. Resumo Anemia é uma complicação frequente e seu impacto na morbimortalidade é bem conhecido em pacientes com doença renal crônica (DRC). A descoberta da hepcidina e de suas funções contribuíram para melhor compreensão dos distúrbios do metabolismo de ferro na anemia da DRC. Hepcidina é um peptídeo produzido principalmente pelos hepatócitos, e através de sua ligação com a ferroportina, regula a absorção de ferro no duodeno e sua liberação das células de estoque. Altas concentrações de hepcidina descritas em pacientes com DRC, principalmente em estádios mais avançados, são atribuídas à diminuição da excreção renal e ao aumento de sua produção. Elevação de hepcidina tem sido associada à ocorrência de infecção, inflamação, aterosclerose, resistência à insulina e estresse oxidativo. Algumas estratégias foram testadas para diminuir os efeitos da hepcidina em pacientes com DRC, entretanto, serão necessários mais estudos para avaliar o impacto de sua modulação no manejo da anemia nessa população.

Resumen Objetivo: Comparar el porcentaje de recurrencias en pacientes con meningiomas grado I de la OMS sometidos a exéresis microquirúrgica. Introducción: En 1957 Simpson estandarizó 5 grados de resección quirúrgica para los meningiomas intracraneanos y el porcentaje de recurrencia relacionado con cada uno, estableciendo el paradigma de que la remoción agresiva de estos tumores junto con fragmentos durales y óseos era necesario para alcanzar la curación. Los avances principalmente en Resonancia Magnética, anatomía patológica y técnica microqurúrgica nos llevan a plantear la relevancia actual de dicha clasificación. Métodos: Se realizó una revisión retrospectiva de los pacientes operados de meningiomas grado I entre Febrero de 2006 y Diciembre de 2015. Se analizaron las imágenes pre y postoperatorias y la anatomía patológica. Las variables se relacionaron mediante un análisis estadístico multivariado estableciendo como estadísticamente significativo una P < 0.05. Resultados: No se objetivó una diferencia estadísticamente significativa entre el número de recidivas y el grado de resección tumoral según Simpson I, II, III o IV (P = 0,3117). Esto puede afirmarse para los grados Simpson I y II en donde el número de pacientes incluidos en la muestra (n) fue alto. Al analizar como factor de recurrencia la localización tumoral tampoco se encontró una diferencia significativa en cuanto al porcentaje de recidivas entre aquellos tumores localizados en la convexidad, base de cráneo y parasagitales (P = 0,2203). Conclusión: Para los meningiomas grado I la exéresis Simpson I no presenta diferencias significativas con la Simpson II en cuanto a la recurrencia tumoral, por lo que aumentar la morbilidad del procedimiento no tendría justificación. Un replanteo de la escala de resección debería idearse teniendo en cuenta la clasificación de la OMS. PMID:29142775

To evaluate diaphragmatic mobility in relation to lung function, respiratory muscle strength, dyspnea, and physical activity in daily life (PADL) in patients with COPD. We included 25 patients with COPD, classified according to the Global Initiative for Chronic Obstructive Lung Disease criteria, and 25 healthy individuals. For all of the participants, the following were evaluated: anthropometric variables, spirometric parameters, respiratory muscle strength, diaphragmatic mobility (by X-ray), PADL, and the perception of dyspnea. In the COPD group, diaphragmatic mobility was found to correlate with lung function variables, inspiratory muscle strength, and the perception of dyspnea, whereas it did not correlate with expiratory muscle strength or PADL. In patients with COPD, diaphragmatic mobility seems to be associated with airway obstruction and lung hyperinflation, as well as with ventilatory capacity and the perception of dyspnea, although not with PADL.

Todos foram submetidos às seguintes avaliações: mensuração antropométrica, espirometria, força muscular respiratória, mobilidade diafragmática (por radiografia), AFVD e percepção de dispneia. No grupo DPOC, houve correlações da mobilidade diafragmática com variáveis de função pulmonar, força muscular inspiratória e percepção de dispneia. Não houve correlações da mobilidade diafragmática com força muscular expiratória e AFVD. A mobilidade diafragmática parece estar associada tanto com a obstrução das vias aéreas quanto com a hiperinsuflação pulmonar em pacientes com DPOC, assim como com a capacidade ventilatória e percep

Stress radionuclide myocardial perfusion scintigraphy (MPS) using adenosine pharmacological vasodilatation is the preferred method in many centres because of its convenience, safety and speed. It can, however, cause bronchospasm and hence its use is avoided in patients with known or suspected bronchospasm. Owing to service pressures, we use technologist-led adenosine stressing for patients referred for MPS studies. We use a modified adenosine infusion protocol under medical supervision for patients with asthma to prevent and minimize adenosine-induced bronchospasm. In this study, we audited our use of this modified protocol in asthmatic patients and compared the side-effect profile with the standard adenosine protocol used in nonasthmatic patients. We audited 50 consecutive patients with asthma attending our department for stress MPS. All patients were taking regular inhalers+/-oral steroids. Patients who had exacerbation of asthma requiring hospital admission during the preceding 6 months were excluded. Before commencing the infusion, two inhaled puffs of salbutamol were administered. A modified adenosine infusion protocol was used, starting initially at a rate of 70 microg/kg/min and increasing to the standard 140 microg/kg/min within 1 min and then maintained for a further 5 min. Technetium-99m tetrofosmin was injected at 3 min. Blood pressure (BP), pulse rate (PR), oxygen saturation and ECG were monitored before, during and at the end of the infusion. All side effects were recorded. Fifty-eight consecutive patients without asthma were included as controls and received the standard 140 microg/kg/min infusion over 6 min. One hundred and eight patients, 50 with asthma and 58 without asthma, were entered into the study. The test was stopped early in two patients (4%) with asthma and 11 patients (19%) without asthma (chi=5.679; P=0.017). Proportionally, more nonasthmatics developed shortness of breath (SOB) (47 of 58, 81% without asthma vs. 35 of 50, 70% with asthma

Molecular Genetic Analysis of Activation-tagged Transcription Factors Thought to be Involved in Photomorphogenesis

DOE Office of Scientific and Technical Information (OSTI.GOV)

Neff, Michael

2011-06-23

Plants utilize light as a source of information via families of photoreceptors such as the red/far-red absorbing phytochromes (PHY) and the blue/UVA absorbing cryptochromes (CRY). The main goal of the Neff lab is to use molecular-genetic mutant screens to elucidate signaling components downstream of these photoreceptors. Activation-tagging mutagenesis led to the identification of two putative transcription factors that may be involved in both photomorphogenesis and hormone signaling pathways. sob1-D (suppressor of phyB-dominant) mutant phenotypes are caused by the over-expression of a Dof transcription factor previously named OBP3. Our previous studies indicate that OBP3 is a negative regulator of light-mediated cotyledonmore » expansion and may be involved in modulating responsiveness to the growth-regulating hormone auxin. The sob2-D mutant uncovers a role for LEP, a putative AP2/EREBP-like transcription factor, in seed germination, hypocotyl elongation and responsiveness to the hormone abscisic acid. Based on photobiological and genetic analysis of OBP3-knockdown and LEP-null mutations, we hypothesize that these transcription factors are involved in both light-mediated seedling development and hormone signaling. To examine the role that these genes play in photomorphogenesis we will: 1) Further explore the genetic role of OBP3 in cotyledon/leaf expansion and other photomorphogenic processes as well as examine potential physical interactions between OBP3 and CRY1 or other signaling components that genetically interact with this transcription factor 2) Test the hypothesis that OBP3 is genetically involved in auxin signaling and root development as well as examine the affects of this hormone and light on OBP3 protein accumulation. 3) Test the hypothesis that LEP is involved in seed germination, seedling photomorphogenesis and hormone signaling. Together these experiments will lead to a greater understanding of the complexity of interactions between photoreceptors

The recently developed Denitrifying Sulfur conversion-associated Enhanced Biological Phosphorus Removal (DS-EBPR) process has demonstrated simultaneous removal of organics, nitrogen and phosphorus with minimal sludge production in the treatment of saline/brackish wastewater. Its performance, however, is sensitive to operating and environmental conditions. In this study, the effects of temperature (20, 25, 30 and 35 °C) and the ratio of influent acetate to propionate (100-0, 75-25, 50-50, 25-75 and 0-100%) on anaerobic metabolism were investigated, and their optimal values/controls for performance optimization were identified. A mature DS-EBPR sludge enriched with approximately 30% sulfate-reducing bacteria (SRB) and 33% sulfide-oxidizing bacteria (SOB) was used in this study. The anaerobic stoichiometry of this process was insensitive to temperature or changes in the carbon source. However, an increase in temperature from 20 to 35 °C accelerated the kinetic reactions of the functional bacteria (i.e. SRB and SOB) and raised the energy requirement for their anaerobic maintenance, while a moderate temperature (25-30 °C) resulted in better P removal (≥93%, 18.6 mg P/L removal from total 20 mg P/L in the influent) with a maximum sulfur conversion of approximately 16 mg S/L. These results indicate that the functional bacteria are likely to be mesophilic. When a mixed carbon source (75-25 and 50-50% acetate to propionate ratios) was supplied, DS-EBPR achieved a stable P removal (≥89%, 17.8 mg P/L for 400 mg COD/L in the influent) with sulfur conversions at around 23 mg S/L, suggesting the functional bacteria could effectively adapt to changes in acetate or propionate as the carbon source. The optimal temperatures or carbon source conditions maximized the functional bacteria competition against glycogen-accumulating organisms by favoring their activity and synergy. Therefore, the DS-EBPR process can be optimized by setting the temperature

The Middle East respiratory syndrome (MERS) is proposed to be a zoonotic disease. Dromedary camels have been implicated due to reports that some confirmed cases were exposed to camels. Risk factors for MERS coronavirus (MERS-CoV) infections in humans are incompletely understood. This study aimed to describe the demographic characteristics, mortality rate, clinical manifestations and comorbidities with confirmed cases of MERS-CoV. Retrospective chart review were performed to identify all laboratory-confirmed cases of MERS-CoV in Saudi Arabia who reported to the Ministry of Health (MOH) of Saudi Arabia and WHO between April 23, 2014 and August 31, 2015. Patients' charts were also reviewed for demographic information, mortality, comorbidities, clinical presentations, health care facility and presented with descriptive and comparative statistics using non parametric binomial test and Chi-square test. Confirmed cases of male patients (61.1%) exceeded those of female patients (38.9%). Infections among Saudi patients (62.6%) exceeded those among non-Saudi patients (37.4%; P = 0.001). The majority of the patients were aged 21-40 years (37.4%) or 41-60 years (35.8%); 43 (22.6%) were aged >61 years, and (8) 4.2% were aged 0-20 years. There was a difference in mortality between confirmed MERS-CoV cases (63.7% alive versus 36.3% dead cases, respectively). Furthermore, fever with cough and shortness of breath (SOB) (n = 39; 20.5%), fever with cough (n = 29; 15.3%), fever (n = 18; 9.5%), and fever with SOB (n = 13; 6.8%), were the most common clinical manifestations associated with confirmed MERS-CoV cases. MERS-CoV is considered an epidemic in Saudi Arabia. The results of the present study showed that the frequency of cases is higher among men than women, in Saudi patients than non-Saudi, and those between 21 to 60 years are most affected. Further studies are required to improve the surveillance associated with MERS-CoV to get definite and clear answers

Hepatectomies have been increasingly recommended and performed in Brazil; they present great differences related to immediate complications. Assessing the immediate postoperative complications in a series of 88 open liver resections. Prospective database of patients subjected to consecutive hepatectomies over nine years. The post-hepatectomy complications were categorized according to the Clavien-Dindo classification; complications presenting grade equal to or greater than 3 were considered major complications. Hepatic resections involving three or more resected liver segments were considered major hepatectomies. Eighty-four patients were subjected to 88 hepatectomies, mostly were minor liver resections (50 cases, 56.8%). Most patients had malignant diseases (63 cases; 71.6%). The mean hospitalization time was 10.9 days (4-43). Overall morbidity and mortality rates were 37.5% and 6.8%, respectively. The two most common immediate general complications were intra-peritoneal collections (12.5%) and pleural effusion (12.5%). Bleeding, biliary fistula and liver failure were identified in 6.8%, 4.5% and 1.1% of the cases, respectively, among the hepatectomy-specific complications. The patients operated in the second half of the series showed better results, which were apparently influenced by the increased surgical expertise, by the modification of the hepatic parenchyma section method and by the increased organ preservation.

Asthma is a chronic disease requiring inhaled treatment and in addition it is a risk factor (RF) of pneumonia. In the oropharyngeal cavity there are numerous species of bacteria that could be dragged to the bronco-alveolar level. to decide whether oral health is a community acquired pneumonia (CAP) RF in asthmatic patients who are taking inhaled treatment, and determining whether the frequency of use of inhalation devices and the type of inhaled drug are CAP RF. Case-control study in asthmatic population with inhaled treatment. We recruited 126 asthmatic patients diagnosed with pneumonia by clinical and radiological criteria (cases) and 252 asthmatics not diagnosed with pneumonia during the last year (controls), matched by age. The main factor of study was the General Oral Health Assessment Index (GOHAI) score. Bivariated analysis showed a statistically significant association of CAP with a GOHAI score≤57 points (poor oral health) (OR 1.69), anticholinergic treatment (OR 2.41), 6 or more inhalations (3.23), chamber use (OR 1.62), FEV 1 (OR 0.98), altered functionality (OR 2.08) and psychiatric disorders or depression (OR 0.41). The multivariated analysis shows an independent association of performing 6 or more inhalations per day (OR 2.74) and functional impairment (OR 1.67). The results suggest that poor oral health may be a CAP RF. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

to estimate the healing rate of complex surgical wounds and its associated factors. retrospective cohort study from 2003 to 2014 with 160 outpatients of a Brazilian university hospital. Data were obtained through consultation of the medical records. Survival function was estimated using the Kaplan-Meier method and Cox regression model to estimate the likelihood of the occurrence of healing. the complex surgical wound healing rate was 67.8% (95% CI: 60.8-74.9). Factors associated with a higher likelihood of wound healing were segmentectomy/quadrantectomy surgery, consumption of more than 20 grams/day of alcohol, wound extent of less that 17.3 cm2 and the length of existence of the wound prior to outpatient treatment of less than 15 days, while the use of hydrocolloid covering and Marlex mesh were associated with a lower likelihood of healing. the wound healing rate was considered high and was associated with the type of surgical intervention, alcohol consumption, type of covering, extent and length of wound existence. Preventive measures can be implemented during the monitoring of the evolution of the complex surgical wound closure, with possibilities of intervention in the modifiable risk factors. estimar a taxa de cicatrização de ferida cirúrgica complexa e seus fatores associados. coorte retrospectiva de 2003 a 2014 com 160 pacientes ambulatoriais de um hospital universitário brasileiro.

To analyze the prevalence and factors associated with multidrug-resistant tuberculosis in Espírito Santo, Brazil. This is a cross-sectional study of cases of tuberculosis tested for first-line drugs (isoniazid, rifampicin, pyrazinamide, ethambutol, and streptomycin) in Espírito Santo between 2002 and 2012. We have used laboratory data and registration of cases of tuberculosis - from the Sistema Nacional de Agravos de Notificação and Sistema para Tratamentos Especiais de Tuberculose. Individuals have been classified as resistant and non-resistant and compared in relation to the sociodemographic, clinical, and epidemiological variables. Some variables have been included in a logistic regression model to establish the factors associated with resistance. In the study period, 1,669 individuals underwent anti-tuberculosis drug susceptibility testing. Of these individuals, 10.6% showed resistance to any anti-tuberculosis drug. The rate of multidrug resistance observed, that is, to rifampicin and isoniazid, has been 5%. After multiple analysis, we have identified as independent factors associated with resistant tuberculosis: history of previous treatment of tuberculosis [recurrence (OR = 7.72; 95%CI 4.24-14.05) and re-entry after abandonment (OR = 3.91; 95%CI 1.81-8.43)], smoking (OR = 3.93; 95%CI 1.98-7.79), and positive culture for Mycobacterium tuberculosis at the time of notification of the case (OR = 3.22; 95%CI 1.15-8.99). The partnership between tuberculosis control programs and health teams working in the network of Primary Health Care needs to be strengthened. This would allow the identification and monitoring of individuals with a history of previous treatment of tuberculosis and smoking. Moreover, the expansion of the offer of the culture of tuberculosis and anti-tuberculosis drug susceptibility testing would provide greater diagnostic capacity for the resistant types in Espírito Santo.

Vergangenheit der Fall war. Cet article propose une nouvelle méthode pour évaluer les effets du travail sur le transfert entre thérapeute et patient. Ce travail est souvent difficile pour le patient, et il peut y avoir un pattern caractéristique de délai entre une înterprétation de transfert et son effet thérapeutique. Pour expliquer ce délai, nous avons évalué les réponses des patients à des interprétatios au cours de séances entières. C'est les narrations des patients sur d'autres, ou Episodes Relationnels (ERs), qui ont constitué les unités de base de cette étude. Dans un échantillon de 3 séances consécutives venant de 3 cas psychodynamiques, nous avons identifié plusieurs moments où le traail sur le transfert semblait avoir un effet inhibitoire initial, mais favorisait le progrès en regardant la séance entière. Nous recommandons pour de futures études sur l'effet des interprétations de prendre des segments plus longs et cliniquement significatifs du récit du patient que ceux utilisés dans le passé. Este artículo propone un nuevo método para evaluar los efectos del trabajo de terapeuta y paciente en la transferencia. El trabajo en la transferencia es, con frecuencia, dificil para el paciente y puede mostrar un lapso característico entre una interpretación transferencial y sus efectos terapéuticos. Para explicar este lapso, hemos evaluado las respuestas del paciente a las interpretaciones a lo largo de sesiones enteras. Como unidad de estudio se usaron las narrativas de los pacientes acerca de otros, o sea, los episodios relacionales (REs). En una muestra de tres sesiones consecutivas tomadas de tres casos psicodinámicos, identificamos varioss casos en los que la trasferencia parecía tener un efecto inicial inhibitorio, aunque se vio que a lo largo de la sesión facilitaba el progreso. Recomendamos que, para examinar los efectos de las interpretaciones, los futuros estudios usen segmentos más largos y clínicamente más significativos

ão arterial e complicações cardiovasculares; porém, os mecanismos envolvidos são complexos e ainda não foram inteiramente elucidados. O objetivo deste estudo foi comparar os níveis de MCP-1 em pacientes com hipertensão resistente (HR) versus pacientes com hipertensão de grau leve a moderado (HAS) e sua associação com a presença ou ausência de hipertrofia ventricular esquerda (HVE) em todos os indivíduos hipertensos. Foram incluídos 256 indivíduos hipertensos: 120 com HR e 136 com HAS. Foi investigada a relação entre os níveis circulantes de MCP-1 e pressão arterial, dados bioquímicos, perfil hematológico e dano cardíaco nos grupos HR e HAS. Os níveis plasmáticos de MCP-1 foram medidos por ELISA e a HVE foi avaliada por ecocardiografia. Não encontramos diferença nos níveis de MCP-1 entre indivíduos com HR e HAS. Por outro lado, encontramos níveis mais baixos de MCP-1 em pacientes com HVE (105 pg/mL [100 - 260 pg/mL] versus 136 pg/mL [100 - 200 pg/mL], respectivamente, p = 0,005] em comparação a pacientes sem HVE. Um modelo de regressão logística ajustado para o índice de massa corporal (IMC), idade, raça, níveis de aldosterona e presença de diabetes e HR mostrou que os níveis medianos de MCP-1 (2,55 pg/mL [1,22 - 5,2 pg/mL], p = 0,01) estiveram independentemente associados com HVE em toda a população de hipertensos. Como os níveis de MCP-1 foram semelhantes em indivíduos tanto com HR quanto HAS e estiveram diminuídos em pacientes hipertensos com HVE, nosso estudo sugere uma possível redução nos níveis de MCP-1 em indivíduos hipertensos com HVE, independe do grau da hipertensão.

estudadas como fator prognóstico no câncer gástrico, sendo relacionadas à diminuição da sobrevida global e aumento do risco de recidiva da doença. Entretanto, sua identificação é limitada pela metodologia convencional, uma vez que podem não ser identificadas pela rotina histopatológica por meio da coloração de H&E. Investigar a presença de células tumorais ocultas através de imunoistoquimica utilizando as citoqueratinas (CK) AE1/AE3 em pacientes com câncer gástrico com linfonodos histologicamente classificados como negativos por H&E. Quarenta pacientes (T1-T4N0) submetidos à gastrectomia potencialmente curativa com linfadenectomia D2 foram avaliados. A presença de metástases, micrometástases e células tumorais isoladas foram correlacionadas com características clínicopatológicas e impacto no estadiamento. Os depósitos tumorais nos linfonodos foram classificados de acordo com o sistema TNM (7º TNM). Um total de 1439 linfonodos foi obtido (~36 por paciente). Células tumorais foram detectadas por imunoistoquimica em 24 linfonodos de 12 pacientes (30%). As células neoplásicas estavam presentes na forma isolada ou em cluster. Invasão tumoral (p=0,002), venosa (p=0,016), linfática (p=0,006) e perineural (p=0,04), assim como resposta linfocítica peritumoral (p=0,012) foram correlacionadas com linfonodos CK-positivos que originalmente eram negativos à H&E. Dois pacientes tiveram o estadiamento alterado, migrando do estádio IB para IIA. Quatro dos 28 CK-negativos (14,3%) e três dos 12 CK-positivos (25%) tiveram recorrência da doença (p=0,65). A imunoistoquimica é meio eficaz para a detecção de células tumorais ocultas em linfonodos, podendo ser recomendada para melhor determinar o estágio do tumor. Ela pode ser útil como técnica complementar à rotina de H&E, de modo a fornecer melhor estadiamento patológico.

The ovarian hyperstimulation syndrome is the combination of increased ovarian volume, due to the presence of multiple cysts and vascular hyperpermeability, with subsequent hypovolemia and hemoconcentration. We report a case of spontaneous syndrome in a singleton pregnancy. This was a spontaneous pregnancy with 12 weeks of gestational age. The pregnancy was uneventful until 11 weeks of gestational age. After that, the pregnant woman complained of progressive abdominal distention associated with abdominal discomfort. She did not report other symptoms. In the first trimester, a routine ultrasonography showed enlarged ovaries, multiples cysts and ascites. Upon admission, the patient was hemodynamically stable, her serum β-hCG was 24,487mIU/mL, thyroid-stimulating hormone was 2.2µUI/mL and free T4 was 1.8ng/dL. All results were within normal parameters. However, levels of estradiol were high (10,562pg/mL). During hospitalization, she received albumin, furosemide and prophylactic dose of enoxaparin. The patient was discharged on the sixth hospital day. RESUMO A síndrome de hiperestimulação ovariana é a combinação do aumento dos ovários, devido à presença de múltiplos cistos e de hiperpermeabilidade vascular, com subsequente hipovolemia e hemoconcentração. Relata-se um caso de síndrome espontânea em uma gestação única. Trata-se de gravidez espontânea com 12 semanas de idade gestacional. A gravidez ocorreu sem intercorrências até 11 semanas de idade gestacional. Após, a gestante passou a se queixar de distensão abdominal progressiva, associada com desconforto abdominal. A paciente não relatava outros sintomas. A ultrassonografia de rotina no primeiro trimestre mostrou ovários aumentados com múltiplos cistos e ascite. No momento da internação, a paciente apresentava-se hemodinamicamente estável, com β-hCG sérico de 24.487mUI/mL, hormônio estimulante da tireoide de 2,2µUI/m e T4 livre de 1,8ng/dL, ou seja, valores dentro dos par

Ectopic penis is usually associated with penoscrotal transposition, and it is rarely observed in isolation. We report a surgical approach for an extremely rare case. A 10-year-old male patient with bilateral cryptorchidism and ectopic penis and scrotum in perineal area, with no penoscrotal transposition, representing an association not yet described in literature. A previous orchiopexy failed due to ectopic scrotum. By means of an inverted Y incision, the penis was mobilized and a perineal skin flap in form of a testicular sac was prepared. Finally orchiopexy was performed. The surgery was essential to treat cryptorchidism and to improve the self-image of the patient. RESUMO O pênis ectópico geralmente ocorre associado à transposição peno-escrotal, sendo raro isoladamente. Relatamos uma abordagem cirúrgica para um caso extremamente raro. Tratava-se de paciente do sexo masculino, 10 anos, com criptorquidia bilateral e pênis e escroto ectópicos, na região perineal, sem transposição peno-escrotal, representando uma associação ainda não descrita na literatura. Orquidopexia prévia sem sucesso, devido à ectopia do escroto. Por meio de uma incisão em Y invertido, mobilizou-se o pênis e preparou-se um retalho da pele perineal em forma de bolsa testicular. Por fim, realizou-se a orquidopexia. A cirurgia foi fundamental para tratar a criptorquidia e promover ganho na autoimagem do paciente.

Objetivo: Describir la anatomía microquirúrgica y los abordajes a la región temporal mesial (RTM), en relación a cavernomas de dicho sector. Materiales y Método: Cinco cabezas de cadáveres adultos, fijadas en formol e inyectadas con silicona coloreada, fueron estudiadas. Además, desde enero de 2007 a junio de 2014, 7 pacientes con cavernomas localizados en la RTM fueron operados por el autor. Resultados: Anatomia: La RTM fue dividida en 3 sectores: Anterior, medio y posterior. Pacientes: 7 enfermos con cavernomas de la RTM fueron operados por el autor. De acuerdo a la ubicacion en la RTM, 4 cavernomas se ubicaron en el sector anterior, 2 cavernomas se localizaron en el sector medio y 1 cavernoma se ubico en el sector posterior. Para el sector anterior de la RTM se utilizo un abordaje transsilviano-transinsular; para el sector medio de la RTM se utilizo un abordaje transtemporal (lobectomia temporal anterior); y para el sector posterior de la RTM se utilizo un abordaje supracerebeloso-transtentorial. Conclusión: Dividir la RTM en 3 sectores nos permite adecuar el abordaje en función a la localización de la lesión. Así, el sector anterior es bien abordable a través de la fisura silviana; el sector medio a través de una vía transtemporal; y el sector posterior por un abordaje supracerebeloso. PMID:26600986

Severe hypertriglyceridemia has been consistently associated with an increased risk of cardiovascular disease and other complications, namely acute pancreatitis. We report a case of a 64 year-old woman with hypertrophic cardiomyopathy and metabolic syndrome with triglyceride level of 3260 mg/dL. Plasma exchange was performed with simultaneous medical treatment to achieve a rapid and effective lowering of triglycerides in order to prevent clinical complications. After three plasmapheresis sessions a marked reduction in triglyceride and total cholesterol levels was observed. Several cases have shown the importance of plasmapheresis in the treatment of acute pancreatitis. We intend to demonstrate the applicability of this technique as primary prophylaxis in the presence of extremely high serum triglyceridemia levels. Resumo A hipertrigliceridemia grave tem sido associada de forma consistente ao aumento do risco cardiovascular e a outras complicações, nomeadamente, pancreatite aguda. Descrevemos um caso de uma mulher de 64 anos, com miocardiopatia hipertrófica e síndrome metabólica com valor sérico de triglicerídeos de 3260 mg/dL. Foi efectuada plasmaferese e optimizado o tratamento médico para alcançar uma redução rápida e efectiva dos níveis dos triglicerídeos, prevenindo complicações clínicas. Após três sessões de plasmaferese, verificou-se uma redução marcada dos triglicerídeos e do colesterol total. Existem alguns casos descritos na literatura demonstrado a importância da plasmaferese no tratamento da pancreatite aguda em contexto de hipertrigliceridemia grave. Os autores pretendem com este caso demonstrar a aplicabilidade desta técnica em contexto de prevenção primária em doentes com níveis de triglicerídeos extremamente aumentados.

2011-04-01

Abundance and distribution of total fatty acids (TFAs) were examined along the physicochemical gradient within an active hydrothermal chimney collected from the Main Endeavour segment of Juan de Fuca Ridge. Approximately 27 fatty acids are identified with a chain-length ranging from C12 to C22. From the exterior to the interior of the chimney walls, the total concentrations of TFAs (∑ TFAs) show a trend of evident decrease. The observed compositions of TFAs are rich in bacterial biomarkers especially monounsaturated fatty acids (MUFAs) and minor branched and cyclopropyl FAs. On the basis of the species-specific FAs and bacterial 16SrRNA gene analysis (Li et al., unpublished data), sulfur-based metabolism appears to be the essential metabolic process in the chimney. Furthermore, the sulfur oxidizing bacteria (SOB) are identified as a basic component of microbial communities at the exterior of the hydrothermal chimney, and its proportion shows an inward decrease while the sulfate reducing bacteria (SRB) have an inverse distribution.

A laboratory-scale Bardenpho process was established to investigate the proper nitrogen loading rate (NLR) when modified spent caustic (MSC) is applied as electron donor and alkalinity source for denitrification. MSC injection induced autotrophic nitrogen removal with sulfur as electron donor and heterotrophic denitrification. The nitrogen removal rate (NRR) did not increase proportionally to NLR. Based on the total nitrogen concentration in the effluent observed in the trials with MSC, the NLR in the influent should not exceed 0.15 kg N/m(3)d in order to satisfy water quality regulations. Microbial communities in the anoxic reactors were characterized by pyrosequencing of 16S rRNA gene sequences amplified by the polymerase chain reaction of DNA extracted from sludge samples. Microbial diversity was lower as MSC dosage was increased, and the injection of MSC caused an increase in SOB belonging to the genus Thiobacillus which is responsible for denitrification using sulfur.

Dados demográficos, cirúrgicos e pós-operatórios foram coletados em um instrumento padronizado e posteriormente compilados e analisados. Dados referentes a 786 pacientes foram encaminhados (média de 43,6 ressecções por cirurgião), sendo 137 excluídos por informações incompletas. Logo, 649 pacientes constituíram nossa população estudada. A média de idade dos pacientes foi de 61,7 anos, 295 eram homens (45,5%), e a maioria - 521 (89,8%) - foi submetida à cirurgia por neoplasia, mais frequentemente classificada como estádio IA. A mediana do tempo de drenagem pleural foi de 3 dias, e a do tempo de internação, 4 dias. Dos 649 procedimentos realizados, 598 (91,2%) foram lobectomias. A taxa de conversão para toracotomia foi de 4,6% (30 casos). Complicações pós-operatórias ocorreram em 124 pacientes (19,1%), sendo pneumonia, escape aéreo prolongado e atelectasia as mais frequentes. A mortalidade em 30 dias foi de 2,0%, tendo como preditores idade avançada e diabetes.

To evaluate the association between obesity and levels of high-sensitivity C-reactive protein (hs-CRP) in patients with heart failure admitted to a tertiary hospital. Cross-sectional study with a consecutive sampling of hospitalized patients with heart failure. Sociodemographic and clinical data were collected, and the nutritional status was assessed through indicators such as body mass index (in kg/m2), waist circumference (in cm), waist-hip ratio, triceps skinfold (in mm) and subscapularis skinfold (in mm). Neck circumference (in cm) was measured as well as serum levels of hs-CRP, in mg/L. Among 123 patients, the mean age was 61.9±12.3 years and 60.2% were male. The median of hs-CRP was 8.87mg/L (3.34 to 20.01). A tendency to an inverse correlation between neck circumference and hs-CRP was detected (r=-0.167; p=0.069). In the multiple linear regression analysis, after adjustment for age, disease severity (NYHA classification III and IV, low ejection fraction, left ventricular dysfunction during diastole), and infectious conditions there was an inverse association between hs-CRP and neck circumference (ß=-0.196; p=0.03) and subscapularis skinfold (ß=-0.005; p=0.01) in the total sample, which was not maintained after the stratification by sex.

To describe the microbiological characteristics and to assess the risk factors for mortality of ventilator-associated tracheobronchitis in a case-control study of intensive care patients. This case-control study was conducted over a 6-year period in a 40-bed medical-surgical intensive care unit in a tertiary care, private hospital in São Paulo, Brazil. Case patients were identified using the Nosocomial Infection Control Committee database. For the analysis of risk factors, matched control subjects were selected from the same institution at a 1:8.8 ratio, between January 2006 and December 2011. A total of 40 episodes of ventilator-associated tracheobronchitis were evaluated in 40 patients in the intensive care unit, and 354 intensive care patients who did not experience tracheobronchitis were included as the Control Group. During the 6-year study period, a total of 42 organisms were identified (polymicrobial infections were 5%) and 88.2% of all the microorganisms identified were Gram-negative. Using a logistic regression model, we found the following independent risk factors for mortality in ventilator-associated tracheobronchitis patients: Acute Physiology and Chronic Health Evaluation I score (odds ratio 1.18 per unit of score; 95%CI: 1.05-1.38; p=0.01), and duration of mechanical ventilation (odds ratio 1.09 per day of mechanical ventilation; 95%CI: 1.03-1.17; p=0.004).

Twenty-nine patients of both genders were evaluated. It was observed weight loss from 108.53 kg to 78.69 kg after the procedure. The variable LDL-c had a significant difference, decreasing approximately 30.3 mg/dl after the surgery. The vitamin B12 serum average levels went from 341.9 pg/ml to 667.2 pg/ml. The triglycerides values were in a range of 129.6 mg/dl-173.3 mg/dl, and 81.9 mg/dl-105.3 mg/dl at the pre- and postoperative respectively. CRP levels fall demonstrated reduction of inflammatory activity. The variable homocysteine was tested in a paired manner and it did not show a significant changing before or after, although it showed a strong correlation with LDL cholesterol. Eligible patients to bariatric surgery frequently present pre-nutritional deficiencies, having increased post-surgical risks when they don´t follow an appropriate nutritional follow-up.

Thus, the Clinical-Functional Vulnerability Index-20 proves to be viable as a triage instrument in the primary health care that identifies frail older adults (older adults at risk of weakening and frail older adults). Avaliar a adequação do Índice de Vulnerabilidade Clínico-Funcional-20 , instrumento de triagem rápida de vulnerabilidade em idosos brasileiros, para utilização pela atenção básica. O estudo incluiu amostra de conveniência de 397 pacientes com idade maior ou igual a 60 anos atendidos em um Centro de Referência para o Idoso e de 52 idosos da mesma idade atendidos na comunidade. Os resultados do questionário, constituído por 20 perguntas, foram comparados com aqueles da Avaliação Geriátrica Ampla, considerada referência para identificação do idoso frágil. Foi avaliada a correlação de Spearman do Índice de Vulnerabilidade Clínico-Funcional-20 com a Avaliação Geriátrica Ampla; a validade foi verificada pela área sob a curva ROC; a confiabilidade foi estimada pelo percentual de concordância entre avaliadores e coeficiente kappa, ambos com ponderação quadrática. Obteve-se ponto de corte com base no critério de maior acurácia. O alfa de Cronbach, medida de consistência interna, foi calculado. O coeficiente de correlação de Spearman foi elevado e positivo em ambos os grupos (0,792 para idosos atendidos no Centro de Referência para o Idoso e 0,305 para idosos da comunidade [p < 0,001]). A área sob a curva ROC para idosos atendidos no Centro de Referência para o Idoso foi substancial (0,903). O ponto de corte obtido foi seis e idosos com pontuação no Índice de Vulnerabilidade Clínico-Funcional-20 acima desse valor tinham forte possibilidade de serem frágeis. Para idosos da comunidade, a concordância ponderada quadrática entre avaliadores foi 99,5% e o coeficiente kappa ponderado quadrático global, 0,94. O alfa de Cronbach foi elevado

A sulfur conversion-associated Enhanced Biological Phosphorus (P) Removal (EBPR) system is being developed to cater for the increasing needs to treat saline/brackish wastewater resulting from seawater intrusion into groundwater and sewers and frequent use of sulfate coagulants during drinking water treatment, as well as to meet the demand for eutrophication control in warm climate regions. However, the major functional bacteria and metabolism in this emerging biological nutrient removal system are still poorly understood. This study was thus designed to explore the functional microbes and metabolism in this new EBPR system by manipulating the deterioration, failure and restoration of a lab-scale system. This was achieved by changing the mixed liquor suspended solids (MLSS) concentration to monitor and evaluate the relationships among sulfur conversion (including sulfate reduction and sulfate production), P removal, variation in microbial community structures, and stoichiometric parameters. The results show that the stable Denitrifying Sulfur conversion-associated EBPR (DS-EBPR) system was enriched by sulfate-reducing bacteria (SRB) and sulfide-oxidizing bacteria (SOB). These bacteria synergistically participated in this new EBPR process, thereby inducing an appropriate level of sulfur conversion crucial for achieving a stable DS-EBPR performance, i.e. maintaining sulfur conversion intensity at 15-40 mg S/L, corresponding to an optimal sludge concentration of 6.5 g/L. This range of sulfur conversion favors microbial community competition and various energy flows from internal polymers (i.e. polysulfide or elemental sulfur (poly-S(2-)/S(0)) and poly-β-hydroxyalkanoates (PHA)) for P removal. If this range was exceeded, the system might deteriorate or even fail due to enrichment of glycogen-accumulating organisms (GAOs). Four methods of restoring the failed system were investigated: increasing the sludge concentration, lowering the salinity or doubling the COD

to evaluate the efficacy of the treatment with hyperbaric oxygen therapy or with topical and intralesional heparin in an animal model of degloving lesions. we conducted an experimental study with adult, male Wistar rats submitted to degloving of the left hind limb and divided into four groups according to the treatment: Group 1 (control) - without treatment; Group 2 (Heparin) - intralesional application at the time of surgery and topically, in the postoperative period, with heparin spray 10,000IU/mL; Group 3 (hyperbaric oxygenation) - daily sessions of 30 minutes in a hyperbaric chamber with 100% oxygen and 2 ATA pressure; Group 4 (positive control) - administration of a single dose of 45 mg/kg of intraperitoneal allopurinol. On the seventh day, we killed the animals, removed the cutaneous flaps and measured the total and necrotic areas, as well as computed the percentage of necrotic area. the mean percentage of necrosis in the control group was 56.03%; in the positive control group it was 51.36% (p<0.45); in the heparin group, 42.10% (p<0.07); and in the hyperbaric oxygen therapy group, 31.58% (p<0.01) . both hyperbaric oxygen and heparin therapies were effective in reducing the percentage of necrosis in the model studied, although only the hyperbaric oxygenation showed statistical significance. avaliar a eficácia do tratamento com oxigenoterapia hiperbárica ou com heparina tópica e intralesional em modelo animal de desluvamentos. estudo experimental, com ratos adultos machos Wistar, submetidos a desluvamento do membro posterior esquerdo e divididos em quatro grupos, de acordo com o tratamento: Grupo 1 (controle) - sem tratamento; Grupo 2 (Heparina) - aplicação intralesional no momento da cirurgia e tópica, no pós operatório, com spray de heparina 10.000UI/mL; Grupo 3 (oxigenação hiperbárica) - sessões diárias de 30 minutos em câmara hiperbárica com 100% de oxigênio e 2 ATA de pressão; Grupo 4 (controle positivo) - administração de dose única

Introducción y objetivo: el IMC puede resultar engañoso para ciertas complexiones corporales, por lo que se han propuesto otros parámetros como la adiposidad (calculada a través de fórmula CUN-BAE,) el índice de Framingham de riesgo cardiovascular (IF) y el índice aterogénico (IA) (rCT/HDL-c) como predictores de riesgo cardiovascular. Se propone comparar estos factores como marcadores de éxito terapéutico tras cirugía en pacientes obesos sometidos a gastrectomía vertical laparoscópica (GVL) como procedimiento de cirugía bariátrica.Material y métodos: realizamos un estudio observacional prospectivo de pacientes sometidos a GVL y con un periodo de seguimiento mínimo de 1 año. Analizamos la evolución de IMC, adiposidad, IF e IA.Resultados: analizamos 140 pacientes. El IMC preoperatorio fue de 49,1 kg/m2, con una adiposidad del 54,8%, un IF 7,54% y un IA de 4,2. A los 12 meses el IMC era de 28,4 kg/m2, con una adiposidad del 39,4%, un IF del 3,7% y un IA de 1,64. En función de estos resultados, a los 12 meses el IMC medio está en rango de sobrepeso, la adiposidad en niveles de obesidad (obesidad: > 25% en hombres y > 35% en mujeres), el IF en rango de riesgo cardiovascular bajo (< 5%) y el IA dentro del rango de normalidad (< 3). Correlacionando estos parámetros observamos que el IMC se correlaciona con la adiposidad tanto en valores preoperatorios (Pearson 0,486; p = 0,004), posoperatorios (Pearson 0,957; p < 0,001), como en la diferencia entre ambos (Pearson 0,606; p = 0,017), lo cual es lógico, porque el IMC se incluye en la fórmula CUN-BAE para el cálculo de la adiposidad. En los valores posoperatorios se objetiva una correlación de la adiposidad con el IF (Pearson 0,814, p = 0,036) y con el IA (Pearson 0,517; p = 0,049). En los valores preoperatorios no se objetivan dichas correlaciones. El IMC no se correlacionó con la adiposidad.Conclusión: la adiposidad se correlaciona con índices de riesgo cardiovascular, como el índice de

The Southeast has high rates of church attendance and HIV infection rates. We evaluated the relationship between church attendance and HIV viremia in a Southeastern US, HIV-infected cohort. Viremia (viral load ≥200 copies/ml) was analyzed 12 months after initiation of care. Univariate and multivariable logistic regression models were fit for variables potentially related to viremia. Of 382 patients, 74 % were virally suppressed at 12 months. Protective variables included church attendance (AOR 0.5; 95 % CI 0.2, 0.9), being on antiretroviral therapy (AOR 0.01; 95 % CI 0.004, 0.04), CD4(+) T lymphocyte count 200-350 cells/mm(3) at care entry (AOR 0.3; 95 % 0.1, 0.9), and education (AOR 0.5; 95 % CI 0.2, 0.9). Variables predicting viremia included black race (AOR 3.2; 95 % CI 1.4, 7.4) and selective disclosure of HIV status (AOR 2.7; 95 % CI 1.2, 5.6). Church attendance may provide needed support for patients entering HIV care for the first time. El Sur Este de los Estados Unidos tiene tasas altas de visitas a iglesias y de infección por VIH.

Cell-derived microvesicles (MVs) are vesicles released from activated or apoptotic cells. However, the levels of MVs in myocardial infarction have been found inconsistent in researches. To assess the association between MVs and myocardial infarction by conducting a meta-analysis. A systematic literature search on PubMed, Embase, Cochran, Google Scholar electronic database was conducted. Comparison of the MVs levels between myocardial infarction patients and healthy persons were included in our study. Standard Mean Difference (SMD) and 95% confidence interval (CI) in groups were calculated and meta-analyzed. 11 studies with a total of 436 participants were included. Compared with the health persons, AMVs [SMD = 3.65, 95% CI (1.03, 6.27)], PMVs [SMD = 2.88, 95% CI (1.82, 3.93),] and EMVs [SMD = 2.73, 95% CI (1.13, 4.34)], levels were higher in patients with myocardial infarction. However, LMVs levels [SMD = 0.73, 95% CI (-0.57, 2.03)] were not changed significantly in patients with myocardial infarction. AMVs, PMVs and EMVs might be potential biomarkers for myocardial infarction. As microvesículas derivadas de células (MVs) são vesículas liberadas de células ativadas ou apoptóticas.

Quarenta e cinco ratos (Rattus norvegicus albinus da linhagem Wistar) foram sorteados em três grupos de 15 submetidos a: irrigação das suturas entéricas com soro fisiológico a 0,9%; aplicação de fita de polissacarídeo do melaço da cana-de-açúcar; e aplicação do gel do mesmo melaço. Os ratos foram submetidos à colectomia esquerda com anastomose primária, e tratados segundo os respectivos grupos. Cinco ratos de cada grupo foram avaliados em diferentes tempos após o procedimento: 30º, 90º e 180º dias de pós-operatório. Foram avaliadas as variáveis de força máxima de ruptura, módulo de elasticidade e deformação específica da força máxima. As variáveis biomecânicas entre os tempos de coleta da pesquisa e os grupos de tratamento foram analisados estatisticamente. As características biomecânicas de força máxima de ruptura e o módulo de elasticidade do corpo de prova permaneceram idênticas, independente do tratamento com soro, fita ou gel de polissacarídeo, e do tempo de tratamento. No entanto, foi evidenciada maior deformação específica da força máxima da parede intestinal, aos 180 dias nos ratos tratados com gel de polissacarídeo de cana-de-açúcar. (p=0,09). Em relação ao controle, foi detectada maior elasticidade da parede intestinal nos ratos tratados com gel de polissacarídeo de cana-de-açúcar, sem alteração de outras características biomecânicas, independente do tipo ou tempo de tratamento.

Interference between maintenance and processing in working memory: the effect of item-distractor similarity in complex span.

PubMed

Oberauer, Klaus; Farrell, Simon; Jarrold, Christopher; Pasiecznik, Kazimir; Greaves, Martin

2012-05-01

Four experiments examined the effect of phonological similarity between items and distractors on complex span performance. Item-distractor similarity benefited serial recall when distractors followed the items they were similar to, but not when distractors preceded the items they were similar to. These findings are predicted by C-SOB (contextual serial order in a box), a computational model of complex span. The model assumes that distractors are involuntarily encoded into memory, being associated to the preceding item's list position. Distractors interfere with items by superposition of distributed representations that are associated to the same position. Superposition distorts item memory; this distortion is less severe when the distractor is similar to the item. Further support for the assumption that distractors are encoded at the position of the preceding item comes from the finding that intrusions of distractors at recall tended to come from the position of the target item. In addition, intruding distractors tend to replace items to which they are similar, showing that lack of distinctiveness also contributes to interference. (c) 2012 APA, all rights reserved.

A novel preterm respiratory mechanics active simulator to test the performances of neonatal pulmonary ventilators

NASA Astrophysics Data System (ADS)

Cappa, Paolo; Sciuto, Salvatore Andrea; Silvestri, Sergio

2002-06-01

A patient active simulator is proposed which is capable of reproducing values of the parameters of pulmonary mechanics of healthy newborns and preterm pathological infants. The implemented prototype is able to: (a) let the operator choose the respiratory pattern, times of apnea, episodes of cough, sobs, etc., (b) continuously regulate and control the parameters characterizing the pulmonary system; and, finally, (c) reproduce the attempt of breathing of a preterm infant. Taking into account both the limitation due to the chosen application field and the preliminary autocalibration phase automatically carried out by the proposed device, accuracy and reliability on the order of 1% is estimated. The previously indicated value has to be considered satisfactory in light of the field of application and the small values of the simulated parameters. Finally, the achieved metrological characteristics allow the described neonatal simulator to be adopted as a reference device to test performances of neonatal ventilators and, more specifically, to measure the time elapsed between the occurrence of a potentially dangerous condition to the patient and the activation of the corresponding alarm of the tested ventilator.

The colourless mat covering organically enriched sediments underlying an intensive salmon farm in Estero Pichicolo, southern Chile, was surveyed by combined 454 PyroTag and conventional Sanger sequencing of 16S/18S ribosomal RNA genes for Bacteria and Eukarya. The mat was dominated by the sulphide-oxidizing bacteria (SOB) Candidatus Isobeggiatoa, Candidatus Parabeggiatoa and Arcobacter. By order of their abundances, sulphate-reducing bacteria (SRB) were represented by diverse deltaproteobacterial Desulfobacteraceae, but also within Desulfobulbaceae, Desulfuromonadaceae and Desulfovibrionaceae. The eukaryotic PyroTags were dominated by polychaetes, copepods and nematodes, however, ciliated protozoans were highly abundant in microscopy observations, and were represented by the genera Condylostoma, Loxophyllum and Peritromus. Finally, the abundant Sulfurimonas/Sulfurovum also suggest the occurrence of zero-valence sulphur oxidation, probably derived from Beggiatoaceae as a result of bacteriovorus infaunal activity or generated as free S(0) by the Arcobacter bacteria. The survey suggests an intense and complex sulphur cycle within the surface of salmon-farm impacted sediments. Copyright © 2015 Elsevier Ltd. All rights reserved.

To describe the current situation of self-management initiatives in Spain. We performed a descriptive study of self-management support initiatives in Spain from the perspective of the patient as expert. Three databases were searched in October 2010 (Pubmed, Scientific Electronic Library Online [SCIELO] and Indice Médico Español [IME]), using the following Keywords «paciente experto» (expert patient), «paciente activo» (active patient) and «apoyo al autocuidado» (self-management support). Web sites were also consulted, using the same key words. Of the initiatives found, we selected those with the most advanced development and continuity, using the perspective of the expert patient (in which patients have an active role) and with a systematic format and methodology. A questionnaire was designed and was sent to the heads of the selected initiatives in the last quarter of 2010. To update the information, the questionnaire was sent again between August and September, 2012. Subsequently, the web sites were visited to review their contents and presence in social networks. Seven initiatives were identified in the autonomous regions of Murcia, Andalusia, Galicia, Castile-La Mancha, Basque Country, and Catalonia. These initiatives used distinct methodologies, formats and assessment systems. In Spain, there is increasing interest in the development of self-management support programs, although their scope is limited and their impact is mostly unknown, except for patient satisfaction. There is a need for studies on results assessment to identify the impact of these initiatives in our setting, as well as for studies on their implementation to encourage the introduction of patient activation initiatives in routine clinical practice.

We conducted a cross-sectional, retrospective study, characterized by classical and molecular epidemiology, involving M. tuberculosis isolates from a regional prison in southern Brazil. Between January of 2011 and August of 2014, 379 prisoners underwent sputum smear microscopy and culture; 53 (13.9%) were diagnosed with active tuberculosis. Of those, 8 (22.9%) presented with isoniazid-resistant tuberculosis. Strain genotyping was carried out by 15-locus mycobacterial interspersed repetitive unit-variable-number tandem-repeat analysis; 68.6% of the patients were distributed into five clusters, and 87.5% of the resistant cases were in the same cluster. The frequency of drug-resistant tuberculosis cases and the rate of recent transmission were high. Our data suggest the need to implement an effective tuberculosis control program within the prison system.

One of the few instruments to evaluate coping skills among patients with chronic illnesses is the Cuestionario de Afrontamiento al Estrés para Pacientes Oncológicos (CAEPO), created initially for cancer patients. We evaluate how well CAEPO applies to patients with non-cancer chronic illnesses. A total of 344 patients (115 with chronic hepatitis C, 120 with inflammatory bowel disease and 109 with recurrent vertigo) completed the CAEPO. Exploratory factor analysis and Cronbach's alpha provide only partial support for the seven factors suggested by the original CAEPO. A streamlined version with fewer dimensions and items may be a better solution for identifying coping strategies among these patients.

Minimally invasive surgery widely used to treat benign disorders of the digestive system, has become the focus of intense study in recent years in the field of surgical oncology. Since then, the experience with this kind of approach has grown, aiming to provide the same oncological outcomes and survival to conventional surgery. Regarding gastric cancer, surgery is still considered the only curative treatment, considering the extent of resection and lymphadenectomy performed. Conventional surgery remains the main modality performed worldwide. Notwithstanding, the role of the minimally invasive access is yet to be clarified. To evaluate and summarize the current status of minimally invasive resection of gastric cancer. A literature review was performed using Medline/PubMed, Cochrane Library and SciELO with the following headings: gastric cancer, minimally invasive surgery, robotic gastrectomy, laparoscopic gastrectomy, stomach cancer. The language used for the research was English. 28 articles were considered, including randomized controlled trials, meta-analyzes, prospective and retrospective cohort studies. Minimally invasive gastrectomy may be considered as a technical option in the treatment of early gastric cancer. As for advanced cancer, recent studies have demonstrated the safety and feasibility of the laparoscopic approach. Robotic gastrectomy will probably improve outcomes obtained with laparoscopy. However, high cost is still a barrier to its use on a large scale. A cirurgia minimamente invasiva amplamente usada para tratar doenças benignas do aparelho digestivo, tornou-se o foco de intenso estudo nos últimos anos no campo da oncologia cirúrgica.

To evaluate the effects that passive cycling exercise, in combination with conventional physical therapy, have on peripheral muscle strength, duration of mechanical ventilation, and length of hospital stay in critically ill patients admitted to the ICU of a tertiary care university hospital. This was a randomized clinical trial involving 38 patients (≥ 18 years of age) on mechanical ventilation who were randomly divided into two groups: control (n = 16), receiving conventional physical therapy; and intervention (n = 22), receiving conventional physical therapy and engaging in passive cycling exercise five days per week. The mean age of the patients was 46.42 ± 16.25 years, and 23 were male. The outcomes studied were peripheral muscle strength, as measured by the Medical Research Council scale, duration of mechanical ventilation, and length of hospital stay. There was a significant increase in peripheral muscle strength (baseline vs. final) in both groups (control: 40.81 ± 7.68 vs. 45.00 ± 6.89; and intervention: 38.73 ± 11.11 vs. 47.18 ± 8.75; p < 0.001 for both). However, the range of increase in strength was higher in the intervention group than in the control group (8.45 ± 5.20 vs. 4.18 ± 2.63; p = 0.005). There were no significant differences between the groups in terms of duration of mechanical ventilation or length of hospital stay. The results suggest that the performance of continuous passive mobilization on a cyclical basis helps to recover peripheral muscle strength in ICU patients.

The persistence of mineral metabolism disorders after renal transplant (RT) appears to possess a negative impact over graft and patient's survival. To evaluate the parameters of mineral metabolism and the persistence of hyperparathyroidism (HPT) in transplanted patients for a 12-month period after the procedure. Retrospective analysis of 41 transplants (18 women- 44%, mean age of 39 ± 15 years) performed in a University Hospital, evaluating changes of calcium (Ca), phosphorus (P) and parathyroid hormone (PTH) and the prevalence of persistent HPT. The patients were divided into two groups accordingly to PTH levels prior to Tx: Group 1 with PTH ≤ 300 pg/mL (n = 21) and Group 2 with PTH > 300 pg/mL (n = 20). The persistency of HPT after transplant was defined as PTH ≥ 100 pg/mL. The evolution of biochemical parameters and the persistency of HPT were analyzed in each group after 1 year of transplant. After a one-year of follow up, 5% of the patients presented hypophosphatemia (p < 2.7 mg/dL), 24% hypercalcemia (Ca > 10.2 mg/dL) and 48% persistency of HPT (PTH ≥ 100 pg/mL). There was a positive correlation between the PTH pre and post Tx (r = 0.42/p = 0.006) and a negative correlation between PTH and Ca pre-Tx (r = -0.45/p = 0.002). However, there was no significant difference among groups 1 and 2 regarding PTH levels pre and post Tx. The findings in this article suggest that mineral metabolism alterations and the persistency of HPT may occur after one year of renal Tx, mainly in patients which present high PTH levels prior toTx.

We collected the data between September and November 2015. We performed a descriptive statistical analysis and comparative analysis of anthropometric, metabolic, biochemical and clinical variables, considering six months before and after surgery. the majority of the patients were female (91.8%), with a higher prevalence (35%) in the age group 18-29 years old, complete high-school education (65.6%) and grade III obesity (60.4%). Six months after surgery, weight and lipid profile reduction were significant in both genders, but the impact on biochemical, anthropometric, metabolic and clinical parameters was significant only in female subjects, with a reduction in morbidities associated with obesity, such as arterial hypertension, diabetes mellitus, dyslipidemia and metabolic syndrome and in the use of drugs to control them. bariatric surgery was effective in weight loss, with improvements in anthropometric, metabolic and biochemical parameters and in the reduction of morbidities associated with obesity. comparar as condições clínicas de pacientes obesos em período pré e pós-operatório de cirurgia bariátrica. estudo descritivo, retrospectivo, de abordagem quantitativa, por meio de consulta ao prontuário de 134 pacientes submetidos à cirurgia bariátrica no período de 2009 a 2014.

To evaluate the relation between diabetes-related distress and the clinical and sociodemographic characteristics of type 2 diabetes mellitus patients. A cross-sectional study based on a secondary analysis of data collected at a specialized care outpatient center in Brazil. Participants completed a questionnaire on sociodemographic and clinical characteristics and the Brazilian version of the Diabetes Distress Scale (B-DDS). About 31% of the 130 eligible patients reported diabetes distress, and the mean B-DDS score was 2.6. Multiple regression analysis showed the B-DDS score was positively correlated with marital status (p=0.0230), use of diet and physical activities for diabetes management (p=0.0180), and use of insulin therapy (p=0.0030). The "emotional burden", "regimen-related distress", and "interpersonal distress" domains from B-DDS were associated with the use of insulin therapy (p=0.0010), marital status (p=0.0110), and the presence of three or more comorbidities (p=0.0175). These findings suggest the clinical and sociodemographic variables are relatively weak predictors of diabetes-related distress. The highest scores in the B-DDS were observed in the emotional burden domain, indicating the presence of diabetes distress among the participants of the study.

Heart failure with preserved ejection fraction (HFpEF) is now an emerging cardiovascular epidemic, being identified as the main phenotype observed in clinical practice. It is more associated with female gender, advanced age and comorbidities such as hypertension, diabetes, obesity and chronic kidney disease. Amyloidosis is a clinical disorder characterized by the deposition of aggregates of insoluble fibrils originating from proteins that exhibit anomalous folding. Recently, pictures of senile amyloidosis have been described in patients with HFpEF, demonstrating the need for clinical cardiologists to investigate this etiology in suspect cases. The clinical suspicion of amyloidosis should be increased in cases of HFPS where the cardio imaging methods are compatible with infiltrative cardiomyopathy. Advances in cardio imaging methods combined with the possibility of performing genetic tests and identification of the type of amyloid material allow the diagnosis to be made. The management of the diagnosed patients can be done in partnership with centers specialized in the study of amyloidosis, which, together with the new technologies, investigate the possibility of organ or bone marrow transplantation and also the involvement of patients in clinical studies that evaluate the action of the new emerging drugs. Resumo A insuficiência cardíaca com fração de ejeção preservada (ICFEP) é hoje uma epidemia cardiovascular emergente, sendo identificada como o principal fenótipo observado na prática clínica.

To determine the Melilla Hospital Nursing Department's attitude towards Moroccan patients. Descriptive ex post facto study. A questionnaire has been handed over to staff, on the Immigration Attitude Scale for Nursing. In general, nurses exhibit negative attitudes towards Moroccan patients, such as: the increase in crime is caused by the arrival of immigrants, those who commit offenses must be expelled from Spain, they take advantage of the Spanish health system and too many resources are devoted to immigration. The worst-rated immigrants are the Moroccans, considering that they do not pay much attention to their personal hygiene and do not adapt to their host countries. It is necessary to work with the nursing staff to change these attitudes. Future degree students must be trained in cultural skills and the care of immigrants will improve with a greater commitment towards cultural differences. Conocer la actitud de enfermería del Hospital de Melilla hacia los pacientes marroquíes. Estudio ex post facto descriptivo. Se ha pasado un cuestionario de Escala de Actitud ante la Inmigración para Enfermería. En general las enfermeras presentan actitudes negativas ante los pacientes marroquíes, como: el aumento de la delincuencia es provocado por la llegada de inmigrantes, los que delinquen deben ser expulsados de España, se aprovechan del sistema sanitario y se dedican demasiados recursos para la inmigración. Los inmigrantes peores valorados son los marroquíes, considerando que son pocos cuidadosos con su higiene personal y no se adaptan a los países de acogida. Es necesario trabajar con el personal de enfermería para que cambien estas actitudes. Las futuras promociones de Grado deben estar formadas en competencias culturales y mejorarán los cuidados a los inmigrantes como un mayor compromiso con la diferencia cultural.

The aim was to identify the main signs and symptoms of cardiac patients hospitalized in a unit of intensive cardiology care in order to infer the main nursing diagnoses (NDs). We performed a cross-sectional study; the sample consisted of 77 randomly selected records. Those records included only patients hospitalized for cardiovascular causes and with electronic chart available. Signs and symptoms identified at admission were psychic (40.3%), compressive dressing on arterial puncture site (33.8%), chest pain (29.9%), tachycardia (22.1%), and hemodynamic instability (20.8%). According to the data collected, we were able to infer that acute pain, excess of fluid volume, decreased cardiac output, spontaneous ventilation impaired, anxiety and impaired skin integrity are priority for the NDs in the studied population.

Although the incidence of gastric (adenocarcinoma) cancer has been decreasing over time, it is still one of the most common malignancies worldwide, and proximal tumours tend to have a worse prognosis. To compare surgical outcomes and prognosis between proximal - excluding tumours of the cardia - and distal gastric cancer. Out of 293 cases reviewed - 209 with distal and 69 with proximal gastric cancer - were compared for clinical and pathological features, stage, surgical outcome, mortality and survival. Statistically, there was no significant difference between patients in both groups regarding mortality (p=0.661), adjuvant chemotherapy (p 0.661), and radiation (p=1.000). However, there was significant difference in the degree of lymph node dissection employed (p=0.002) and the number of positive lymph nodes resected (p=0.038) between the two groups. The odds of death at five years for patients who had a D0 dissection was three times greater (odds ratio 2.78; (95%CI 1.33-5.82) than that for patients who had a D2 dissection, while for patients who had a D1 dissection the odds ratio was only 1.41 (95%CI 0.71-2.83) compared to D2-dissected patients. Although no significant differences were found between proximal and distal gastric cancer, the increased risk of death in D0- and D1-dissected patients clearly suggests an important role of radical D2 lymph node dissection in survival.

Atraves do uso da teoria das redes complexas, chegou-se a uma expressao para o limite de percolacao e, do mesmo modo, demonstrou-se que “hopping” entre fibras adjacentes resulta numa expressao que corresponde a um regime de desordem fraca. No trabalho desenvolvido tambem foi calculado os expoentes criticos, atraves da teoria das redes, para um sistema 3D composto por cilindros impenetraveis com uma interacao de curto alcance, demonstrando que os expoentes criticos estao relacionados por uma relacao de hiperescala comum para 3D e nao pertencem a mesma classe de universalidade como a percolacao numa rede. A aplicacao do modelo desenvolvido a compositos de epoxy reforcada, com diferentes metodos de dispersao de nanofibras de carbono, revelou que os metodos de dispersao usados para preparar os compositos tem uma forte influencia nas propriedades eletricas que podem ser capturadas pelo modelo. Neste contexto, ficou ainda demonstrado que a condutividade eletrica pode ser descrita por um regime de desordem fraca, isto ´e, um regime onde todas as conexoes fibra-fibra participam na condutividade do composito. O modelo desenvolvido foi aplicado igualmente a compositos de poly (vinylidene fluoride) reforcado com nanotubos de carbono com diferentes tratamentos de termicos de oxidacao. Verificou-se que os tratamentos de superficie aumentam o limite de percolacao e diminuem a condutividade. Nesta dissertacao provamos ainda que a condutividade do composito pode ser atribuida a um mecanismo de “hopping”, fortemente afetado pelos tratamentos de superficie dos reforcos.

Despite knowing that resveratrol has effects on blood vessels, blood pressure and that phytostrogens can also improve the endothelium-dependent relaxation/vasodilation, there are no reports of reveratrol's direct effect on the endothelial function and blood pressure of animals with estrogen deficit (mimicking post-menopausal increased blood pressure). To verify the effect of two different periods of preventive treatment with resveratrol on blood pressure and endothelial function in ovariectomized young adult rats. 3-month old female Wistar rats were used and distributed in 6 groups: intact groups with 60 or 90 days, ovariectomized groups with 60 or 90 days, and ovariectomized treated with resveratrol (10 mg/kg of body weight per day) for 60 or 90 days. The number of days in each group corresponds to the duration of the experimental period. Vascular reactivity study was performed in abdominal aortic rings, systolic blood pressure was measured and serum nitric oxide (NO) concentration was quantified. Ovariectomy induced blood pressure increase 60 and 90 days after surgery, whereas the endothelial function decreased only 90 days after surgery, with no difference in NO concentration among the groups. Only longer treatment (90 days) with resveratrol was able to improve the endothelial function and normalize blood pressure. Our results suggest that 90 days of treatment with resveratrol is able to improve the endothelial function and decrease blood pressure in ovariectomized rats. Apesar de se saber que o resveratrol apresenta efeitos sobre a pressão arterial e os vasos sanguíneos, e que os fitoestrógenos podem melhorar o relaxamento/vasodilatação dependente do endotélio, não há relatos do efeito direto do resveratrol sobre a pressão arterial e a função endotelial em animais com deficiência de estrógeno (mimetizando a pressão arterial aumentada pós-menopausa).

We report real time imaging of the oxygen reduction reactions (ORRs) in all solid state sodium oxygen batteries (SOBs) with CuO nanowires (NWs) as the air cathode in an aberration-corrected environmental transmission electron microscope under an oxygen environment. The ORR occurred in a distinct two-step reaction, namely, a first conversion reaction followed by a second multiple ORR. In the former, CuO was first converted to Cu 2 O and then to Cu; in the latter, NaO 2 formed first, followed by its disproportionation to Na 2 O 2 and O 2 . Concurrent with the two distinct electrochemical reactions, the CuO NWs experienced multiple consecutive large volume expansions. It is evident that the freshly formed ultrafine-grained Cu in the conversion reaction catalyzed the latter one-electron-transfer ORR, leading to the formation of NaO 2 . Remarkably, no carbonate formation was detected in the oxygen cathode after cycling due to the absence of carbon source in the whole battery setup. These results provide fundamental understanding into the oxygen chemistry in the carbonless air cathode in all solid state Na-O 2 batteries.

Alguns fenômenos de outbursts em Be-X sugerem a existência, mesmo que temporária, de um disco de acresção quando da passagem do objeto compacto pelo periastro orbital. Neste trabalho avaliamos a possibilidade de formação do disco de acresção em sistemas Be+estrela de neutrons e Be+anã branca, e a influência da excentricidade orbital na ocorrência deste fenômeno. Utilizamos a expressão analítica para o momento angular específico da matéria constituinte de um meio em expansão lenta, como é o caso do disco circunstelar das estrelas Be, proposta por Wang(1981), sob a condição básica de que o raio de circularização deva ser maior do que o raio de Alfvén. Concluímos que existe um limite para o período orbital do sistema acima do qual não é possível a formação do disco de acresção, e que este valor aumenta para sistemas com excentricidade orbital maior.

The clinical definition of cardiogenic shock is that of a low cardiac output and evidence of tissue hypoxia in the presence of adequate blood volume. Cardiogenic shock is the main cause of death related to acute myocardial infarction (AMI), with a mortality rate of 45-70% in the absence of aggressive and highly specialized technical care. The intra-aortic balloon pump (IABP) is one of the most widely used mechanical assisting devices. During the last two decades, about 42% of patients with AMI who evolved with cardiogenic shock received mechanical circulatory assistance with IABP. Its clinical indication has been based on non-randomized studies and registry data. Recent studies have shown that the use of IABP did not reduce 30-day mortality in patients with AMI and cardiogenic shock treated with the strategy of early myocardial revascularization as the planned primary objective. The guidelines of the American Heart Association and of the European Society of Cardiology have reassessed their recommendations based on the results of meta-analyzes, including the IABP-SCHOCK II Trial study, which did not evidence an increase in survival of patients who received mechanical support with IABP. This review article addresses the clinical impact of IABP use in the cardiogenic shock caused by AMI. RESUMO A definição clínica de choque cardiogênico é a de um quadro de baixo débito cardíaco e evidência de hipóxia tecidual, na presença de volemia adequada.

To evaluate pulmonary function and functional capacity in children and adolescents with sickle cell disease. This was a cross-sectional study involving 70 children and adolescents (8-15 years of age) with sickle cell disease who underwent pulmonary function tests (spirometry) and functional capacity testing (six-minute walk test). The results of the pulmonary function tests were compared with variables related to the severity of sickle cell disease and history of asthma and of acute chest syndrome. Of the 64 patients who underwent spirometry, 15 (23.4%) showed abnormal results: restrictive lung disease, in 8 (12.5%); and obstructive lung disease, in 7 (10.9%). Of the 69 patients who underwent the six-minute walk test, 18 (26.1%) showed abnormal results regarding the six-minute walk distance as a percentage of the predicted value for age, and there was a ≥ 3% decrease in SpO2 in 36 patients (52.2%). Abnormal pulmonary function was not significantly associated with any of the other variables studied, except for hypoxemia and restrictive lung disease. In this sample of children and adolescents with sickle cell disease, there was a significant prevalence of abnormal pulmonary function. The high prevalence of respiratory disorders suggests the need for a closer look at the lung function of this population, in childhood and thereafter.

Autism spectrum disorders: an updated guide for genetic counseling.

Griesi-Oliveira, Karina; Sertié, Andréa Laurato

2017-01-01

Autism spectrum disorder is a complex and genetically heterogeneous disorder, which has hampered the identification of the etiological factors in each patient and, consequently, the genetic counseling for families at risk. However, in the last decades, the remarkable advances in the knowledge of genetic aspects of autism based on genetic and molecular research, as well as the development of new molecular diagnostic tools, have substantially changed this scenario. Nowadays, it is estimated that using the currently available molecular tests, a potential underlying genetic cause can be identified in nearly 25% of cases. Combined with clinical assessment, prenatal history evaluation and investigation of other physiological aspects, an etiological explanation for the disease can be found for approximately 30 to 40% of patients. Therefore, in view of the current knowledge about the genetic architecture of autism spectrum disorder, which has contributed for a more precise genetic counseling, and of the potential benefits that an etiological investigation can bring to patients and families, molecular genetic investigation has become increasingly important. Here, we discuss the current view of the genetic architecture of autism spectrum disorder, and list the main associated genetic alterations, the available molecular tests and the key aspects for the genetic counseling of these families. RESUMO O transtorno do espectro autista é um distúrbio complexo e geneticamente heterogêneo, o que sempre dificultou a identificação de sua etiologia em cada paciente em particular e, por consequência, o aconselhamento genético das famílias.

Kidney transplants with expanded criteria donor have been associated with improved patient survival compared to those who remain on dialysis. To compare renal function and survival of the kidney graft of deceased donor with expanded criteria and standard criteria over a year in a single transplant center. 255 kidney transplant recipients with deceased donor were included in the study between the years 2011 to 2013 and they were separated into two groups according to the type of donor (expanded criteria donor - ECD - and standard criteria donor - SCD). 231 deceased donor transplants (90.6%) were performed with standard criteria donor (SCD) and 24 (9.4%) with expanded criteria donor (ECD). There was no difference in the prevalence of delayed graft function - DGF - (62.9% vs. 70.8%; p = 0.44). Expanded criteria donor group had lower glomerular filtration rate (GFR) at the end of the 1st year (56.8 ± 26.9 vs. 76.9 ± 23.7; p = 0.001). Patient survival was significantly lower in the ECD group, but the graft survival was not different after death-censored analysis. The ECD group was associated with significantly lower levels of GFR during the first year of transplant and a lower patient survival at the 1st year when compared to the SCD.

Among the deaths due to cardiorespiratory arrest, the study aimed to identify factors indicating underreported encephalic death cases. The Acute Physiology and Chronic Health Evaluation II and Sepsis Related Organ Failure Assessment severity indexes were applied in the protocols. Based on this, a scale was built and sent to five experts for assessment of the scale content, and subsequently, it was computerized by using a prototyping model. 34 underreported encephalic death cases were identified in the medical records of patients with cardiorespiratory arrest. Statistically significant differences were found in the Wilcoxon test between the scores of hospital admissions in the intensive care unit and the opening of the encephalic death protocol for both severity indexes. the prototype was effective for identifying potential organ donors, as well as for the identification of the degree of organ dysfunction in patients with encephalic death. desenvolver protótipo de escala informatizada para busca ativa de potenciais doadores de órgãos e tecidos. pesquisa metodológica, com análise de 377 prontuários eletrônicos de pacientes que evoluíram a óbito, por morte encefálica, ou parada cardiorrespiratória, nas unidades de terapia intensiva de hospital terciário.

Cada vez es mayor el número de ancianos con diagnóstico de cáncer que acuden a las consultas de Oncología Médica. El proceso del envejecimiento y la gran variabilidad existente en la población geriátrica implican que, para hacer un abordaje adecuado del paciente, se deba considerar la edad fisiológica del anciano, y no su edad biológica. Para ello, es preciso hacer una evaluación somera, específica e individualizada a cada uno de los ancianos con diagnóstico de cáncer que acudan a nuestra consulta. La valoración geriátrica integral (VGI) es la herramienta clave que permite evaluarlos de forma adecuada, e incluso orienta la toma de decisiones "personalizada" en los ancianos con diagnóstico de cáncer. Dado que la VGI consume mucho tiempo en la consulta diaria, se están desarrollando distintas herramientas de cribado que permitan acortar la atención al paciente, al seleccionar aquellos ancianos que deban someterse a una VGI y aquellos en los que esta no sea necesaria. Se han publicado distintos modelos de VGI en la Oncogeriatría y se han desarrollado distintas herramientas de cribado de fragilidad; los más conocidos son el cuestionario Vulnerable Elders Survey-13 (VES-13) y el cuestionario G-8. En este artículo se hace una revisión acerca de la evidencia científica existente en cuanto a la atención y valoración del anciano oncológico, así como los distintos parámetros de los que se disponen para la toma de decisiones definitiva. Dichos datos reflejan el papel de la Oncogeriatría como la vía para ofrecer una atención global óptima a este grupo poblacional.

Resumen IntroducciÓn: El papiloma invertido es una neoplasia benigna de los senos paranasales localmente agresiva con alto potencial de recurrencia y de malignización. La extensión intracraneal es infrecuente y más aún, la penetración dural, asociándose a menudo a la recurrencia de la enfermedad o a su degeneración en carcinoma de células escamosas. Caso clínico: Presentamos el caso de una paciente de 32 años que consultó por lesión exofítica en fosa nasal derecha y exoftalmos, asociada a cefalea, anosmia y disgeusia. Se estudió con TC cerebro, macizo facial y RM de encéfalo que evidencian lesión en fosa nasal derecha con ocupación de senos aéreos, osteólisis de pared medial orbitaria y base de cráneo anterior e invasión intracraneal frontal derecha, con efecto de masa y compresión del parénquima encefálico adyacente. Intervención: Se realizó una nasofibroscopía en primer tiempo con diagnóstico anatomopatológico de papiloma invertido y posteriormente resección de la lesión mediante doble abordaje más reconstrucción de la fosa craneal anterior. Se obtuvo diagnóstico definitivo de papiloma invertido de tipo Schneideriano con áreas de transformación atípica in situ. La paciente evolucionó de forma favorable y sin complicaciones, con permeabilidad de vía aérea superior, sin signos de recidiva lesional luego de 4 años de seguimiento. Conclusión: La invasión intracraneal de esta patología es sumamente infrecuente. Cuando existe, es indicador de agresividad y potencial recidiva, por lo que la exéresis completa de la misma define el pronóstico de la enfermedad. PMID:29430328

Resumen Introducción: La patología de la unión cráneo-cervical es poco frecuente en la práctica neuroquirúrgica diaria. En general la mayor parte de estas lesiones son de origen traumático o reumatológico. La inestabilidad atlanto-axial de origen inflamatorio (Síndrome de Grisel) es una rara entidad de la que solo se han reportado 16 casos adultos en la literatura. Esta patología se caracteriza por el desarrollo de una lesión osteolítica a nivel de la articulación atlanto-axoidea posterior a un evento infeccioso, generalmente de las vías aéreas superiores. Descripción del caso: Presentamos el caso de una paciente de 76 años quien concurre en consulta por un cuadro clínico de inestabilidad cráneo espinal secundaria a una lesión osteolítica, con compromiso de C1 y C2. La sintomatología comenzó posteriormente a un proceso infeccioso respiratorio. Se realizó una fijación occípito-cervical posterior y una Odontoidectomía con descompresión anterior por vía endoscópica transnasal. La paciente evolucionó con resolución completa de los síntomas. Los cultivos fueron negativos y el estudio de anatomía patológica concluyó cambios inflamatorios inespecíficos. Conclusión: Hasta hace algunos pocos años la única opción para abordar esta patología era la vía transoral con técnica microquirúrgica. Hoy en día la endoscopía nos brinda muchas ventajas técnicas por lo que constituye una opción a tener en cuenta en la planificación de los abordajes a la unión cráneo-cervical. PMID:29430326

Resumen Los quistes neuroentéricos (QNE) son lesiones raras, congénitas y benignas, causadas por la comunicación persistente o anormal entre el neuroectodermo, la notocorda y el endodermo. Se presentan principalmente en pacientes pediátricos y adultos jóvenes, asociados a otras malformaciones vertebromedulares, gastrointestinales y respiratorias. Son lesiones intradurales extramedulares, siendo excepcional su presentación intramedular. El objetivo del presente artículo es reportar un caso de QNE intramedular cervical en un adulto joven, sin malformaciones concomitantes. El tratamiento quirúrgico es de elección según toda la bibliografía consultada, y por su alta tasa de recurrencia, el objetivo debe ser la resección total. El seguimiento con RMN es recomendado en resecciones subtotales. PMID:29900034

El cáncer es un problema sanitario de primera magnitud a escala mundial. Su tratamiento es uno de los mayores campos de innovación y desarrollo en medicina. La visión del cáncer como una enfermedad sistémica, heterogénea y de una elevada complejidad hace que los enfermos deban recibir una atención oncológica de calidad, proporcionada por equipos multidisciplinares altamente cualificados. Además de la gran incidencia de malnutrición en estos pacientes, la intervención nutricional precoz puede mejorar su pronóstico, aumentar la calidad de vida y disminuir la tasa de complicaciones de la enfermedad. Por ello, es necesaria una estrecha colaboración entre el oncólogo y el experto en nutrición.

Resumen Antecedentes La presencia de metástasis en los ganglios linfáticos (MGL) en la prostatectomía radical de rescate (PRs) se asocia con un mal pronóstico. Los factores predictivos de resultados en este contexto siguen siendo indeterminados. El objetivo fue evaluar el papel de número de ganglios linfáticos positivos sobre el resultado de los pacientes con MGL después de PRs y para el cáncer de próstata de radio-recurrente. Material y métodos Se analizaron los datos de una cohorte consecutiva de 215 hombres tratados con PRr en una sola institución. Se utilizaron los modelos de regresión de riesgos proporcionales de Cox univariante para la recurrencia bioquímica (RBQ) y los resultados metastásicos, con el antígeno prostático específico, la puntuación de Gleason, la extensión extraprostática, la invasión de vesículas seminales, el tiempo entre la terapia de radiación y PRr y el número de ganglios positivos como factores predictivos. Resultados De los 47 pacientes con MGL, 37 desarrollaron RBQ, 11 desarrollaron metástasis a distancia y 4 fallecieron con una mediana de seguimiento de 2,3 años para los supervivientes. El riesgo de metástasis aumentó con mayores niveles preoperatorios de PSA (HR 1,19 por 1 ng/ml; IC del 95%: 1,06, 1,34; p = 0,003). Los factores predictivos restantes no alcanzaron niveles convencionales de significación. Sin embargo, la eliminación de 3 o más ganglios linfáticos positivos demostró una asociación positiva, como se esperaba, con enfermedad metastásica (HR 3,44, IC: 0,91, 13,05; p = 0,069) en comparación con uno o dos ganglios positivos. Del mismo modo, la presencia de extensión extraprostática, invasión de vesículas seminales y grado de Gleason superior a 7 también demostraron una asociación positiva con un mayor riesgo de metástasis, con índices de riesgo de 3,97 (IC del 95% 0,50; 31,4; p = 0,2), 3,72 (IC 95% 0,80, 17,26; p = 0,1) y 1,45 (IC del 95% 0,44, 4,76; p = 0,5), respectivamente

Problems Caused by Microbes and Treatment Strategies Monitoring and Preventing Reservoir Souring Using Molecular Microbiological Methods (MMM)

Gittel, Antje

The injection of seawater during the process of secondary oil recovery in offshore oilfields supplies huge amounts of sulphate to the prokaryotic reservoir communities. Together with the presence of oil organics and their degradation products as electron donors, this facilitates the enrichment and growth of sulphate-reducing prokaryotes (SRP) in the reservoir, as well as in pipings and top-side installations (Sunde and Torsvik, 2005; Vance and Thrasher, 2005). The activity of SRP causes severe economic problems due to the reactivity and toxicity of the produced hydrogen sulphide (H2S), one of the major problems being reservoir souring. Besides the use of broad-spectrum biocides or inhibitors for sulphate reduction, the addition of nitrate effectively decreased the net production of H2S in model column studies (Myhr et al., 2002; Hubert et al., 2005; Dunsmore et al., 2006) and field trials (Telang et al., 1997; Bødtker et al., 2008). The mechanisms by which nitrate addition might affect souring control are (i) the stimulation of heterotrophic nitrate-reducing bacteria (hNRB) that outcompete SRP for electron donors, (ii) the activity of nitrate-reducing, sulphide-oxidising bacteria (NR-SOB), and (iii) the inhibition of SRP by the production of nitrite and nitrous oxides (Sunde and Torsvik, 2005; Hubert and Voordouw, 2007).

In this paper, a method of determination of uranium 238 and 234 in mining waters of Andrzej kaolin open pit in Zarów (Lower Silesia) is presented. The method is based on independent measurements of alpha and beta radiation intensities by means of a liquid scintillation spectrometer alpha/beta. The initial volume of water sample was 3 dm3, then it was diminished by chemical preparation to 6 cm3, and then 12 cm3 of scintillator was added. The lower limit of detection (for the measurement time of 8 h) for both 234U and 238U amounted to 0.02 Bq/dm3. For determination of the uranium content in ferruginous sediments precipitating from mining waters of the above-mentioned open pit, gamma ray spectrometry was used. The obtained results may be viewed as a contribution to studies on anomalous uranium concentration within this kaolin deposit. The elevated uranium content, in comparison with its average concentration in the Earth crust, is characteristic for parent rocks of Andrzej kaolin deposit, which are granitoids of Strzegom-Sobótka massif. In connection with it, the high uranium content can be observed not only in kaolin and weakly kaolinised granitoids from the deposit in question, but also in mining waters genetically related with them.

To interpret the meanings attributed to the experience of bladder cancer among survivors in therapeutic follow-up. Qualitative methodological approach, based on medical anthropology and narrative methodology. After approval by the research ethics committee of a public university hospital, data were collected from January 2014 to February 2015, by means of recorded semi-structured interviews, direct observation and field journal entries on daily immersion with a group of six men and six women, aged between 57 and 82 years, in therapeutic follow-up. Narratives were analyzed by means of inductive thematic analysis. The meanings revealed difficulties with the processes of disease and treatment, such as breakdown of normal life, uncertainty about the future due to possible recurrence of the disease, difficulty with continuity of care and emotional control, relating it to conflicting ways of understanding the present life. Thus, the meaning of this narrative synthesis is paradox. Interpretation of the meaning of experience with bladder cancer among patients provides nurses with a comprehensive view of care, which encompasses biological, psychological and social dimensions, and thereby systematizes humanized care. Interpretar o significado atribuído à experiência do câncer de bexiga entre sobreviventes em seguimento terapêutico. Empregou-se a abordagem metodológica qualitativa, embasado pela antropologia médica e método narrativo. Após aprovação do Comitê de Ética, os dados foram coletados de janeiro 2014 a fevereiro de 2015, por meio de entrevistas semiestruturadas gravadas, observação direta e registros no diário de imersão com grupo de seis homens e seis mulheres, entre 57 e 82 anos, em seguimento terapêutico em um hospital público universitário. As narrativas foram analisadas por meio da análise temática indutiva. Os sentidos revelam as dificuldades com o processo da doença e do tratamento, como rupturas na vida, futuro incerto pela

para a formulação de uma política específica. O Espaço Aids constituiu-se como produto do encontro da trajetória de agentes de diversos campos sociais (médico, científico, político e burocrático). Um espaço específico de relações, que possibilitou a formulação de uma política para o controle da epidemia da aids, mas onde também estava em disputa a autoridade de falar sobre o significado da doença, suas formas de prevenção e tratamento. A análise mostrou como as estruturas (governos democráticos no estado de São Paulo e no âmbito nacional, com sanitaristas assumindo posições importantes) e a ausência de terapia específica contribuíram para que agentes sociais com disposições e formações diversas formulassem uma política que priorizou inicialmente a prevenção. A ascensão do movimento sanitário, a constituição do SUS e a dominância do campo médico no Espaço Aids contribuíram para a valorização do tratamento, como parte das medidas de controle da epidemia. Essas condições possibilitaram a formulação de uma política baseada na integralidade das ações, articulando prevenção e tratamento, na década seguinte, com importante participação da burocracia estatal e de pesquisadores.

cardiotoxicidade induzida por antraciclina é de vital importância para o equilíbrio entre o risco cardíaco e o potencial tratamento do câncer. Investigar se a análise por speckle-tracking pode fornecer uma medida sensível e precisa na detecção de lesão ventricular esquerda induzida por doxorrubicina. Ratos Wistar foram divididos em 4 grupos de 8 ratos cada, e doxorrubicina foi administrada intraperitonealmente em intervalos semanais de até 4 semanas. Grupo 1: 2,5 mg/kg/semana; Grupo 2: 3 mg/kg/semana; Grupo 3: 3,5 mg/kg/semana; Grupo 4: 4 mg/kg/semana. Foram utilizados 5 ratos adicionais como controles. As imagens ecocardiográficas foram obtidas na linha basal e 1 semana após a última dose do tratamento. Foram analisados o strain radial (Srad) e circunferencial (Scirc) e as taxas de strain radial (TSrad) e circunferencial (TScirc). Após o experimento, a troponina cardíaca I (cTnI) foi analisada e as amostras cardíacas foram avaliadas histologicamente. Após a exposição à doxorrubicina, a FEVE foi significativamente reduzida no grupo 4 (p = 0,006), mas permaneceu estável nos outros grupos. Entretanto, após o tratamento, os Srads foram reduzidos nos grupos 2, 3 e 4 (p < 0,05). A diminuição dos Srads foi correlacionada com cTnI (rho = -0,736, p = 0,000) e os escores de cardiomiopatia (rho = -0,797, p = 0,000). O strain radial pode fornecer um índice sensível e não-invasivo na detecção precoce da lesão miocárdica induzida pela doxorrubicina. As alterações do strain radial apresentaram correlação significativa com lesões miocárdicas e níveis séricos de troponina I cardíaca, indicando que esse parâmetro pode avaliar com precisão a gravidade da cardiotoxicidade.

A combinacao das caracteristicas do diamante microcristalino (MCD) e nanocristalino (NCD), tais como elevada adesao do MCD e a baixa rugosidade superficial e baixo coeficiente de atrito do NCD, e ideal para aplicacoes tribologicas exigentes. Deste modo, o presente trabalho centrou-se no desenvolvimento de revestimentos em multicamada MCD/NCD. Filmes com dez camadas foram depositados em amostras de cerâmicos de Si3N4 pela tecnica de deposicao quimica em fase vapor assistida por filamento quente (HFCVD). A microestrutura, qualidade do diamante e adesao foram investigadas usando tecnicas como SEM, AFM, espectroscopia Raman, DRX, indentacao Brale e perfilometria otica 3D. Diversas geometrias para aplicacoes distintas foram revestidas: discos e esferas para testes tribologicos a escala laboratorial, e para testes em servico, aneis de empanques mecânicos e pastilhas de corte para torneamento. Nos ensaios tribologicos esfera-sobre-plano em movimento reciproco, sob 10-90% de humidade relativa (RH), os valores medios dos coeficientes de atrito maximo e em estado estacionario sao de 0,32 e 0,09, respetivamente. Em relacao aos coeficientes de desgaste, observou-se um valor minimo de cerca de 5,2x10-8 mm3N-1m-1 para valores intermedios de 20-25% de RH. A humidade relativa tem um forte efeito sobre o valor da carga critica que triplica a partir de 40 N a 10% RH para 120 N a 90% de RH. No intervalo de temperaturas 50-100 °C, as cargas criticas sao semelhantes as obtidas em condicoes de baixa RH ( 10-25%).

Challenging questions in treating bronchitis.

Whatever facts we gather and no matter how many we have, you and I must eventually put the journal down and pick up our stethoscope, pen, and prescription pad and go to work. Hopefully we can do better than, "Therapy is not uniform and specific antibiotic regimens are usually selected based on local tribal custom." We can discard an old paradigm, "The absence of data bears no relation to the strength of opinion." Personally, I have used these new scientific data before I reached my conclusion. I have developed 10 points to structure my new approach. I invite you to compare my conclusions to yours. 1. In acute bronchitis, in otherwise healthy adults, my preference is to not prescribe an antibiotic. If I do, it is not over the phone. You should want to see and examine the patient. If there are no helpful hints to etiology, I choose a newer macrolide for those under age 50 and use a short course, five-seven days. For patients over age 50, especially if they are "healthy smokers," consider a short course of cefuroxime. (You can see, even in these acute bronchitis patients, you want an antibiotic effective against today's pathogens.) 2. In all chronic bronchitis patients, prevention of further damage to the airways should be attempted by instituting a program of smoking cessation and appropriate immunizations against influenza and pneumococcus. 3. Treatment outcomes will also improve if we recognize that in some patients the progressing SOB, cough, and increasing sputum production are due to congestive heart failure and not due to infection. I try to think about congestive heart failure in all of my patients, but especially in those with known heart disease and cardiomegaly on their chest x-ray. 4. Routine pulmonary function testing is important in smoking patients. Physicians underestimate the degree of obstruction present when they rely on physical exam alone. Hopefully long before the patient's acute illness you have established whether or not obstruction is present

The Microbial Sulfur Cycle at Extremely Haloalkaline Conditions of Soda Lakes

Soda lakes represent a unique ecosystem with extremely high pH (up to 11) and salinity (up to saturation) due to the presence of high concentrations of sodium carbonate in brines. Despite these double extreme conditions, most of the lakes are highly productive and contain a fully functional microbial system. The microbial sulfur cycle is among the most active in soda lakes. One of the explanations for that is high-energy efficiency of dissimilatory conversions of inorganic sulfur compounds, both oxidative and reductive, sufficient to cope with costly life at double extreme conditions. The oxidative part of the sulfur cycle is driven by chemolithoautotrophic haloalkaliphilic sulfur-oxidizing bacteria (SOB), which are unique for soda lakes. The haloalkaliphilic SOB are present in the surface sediment layer of various soda lakes at high numbers of up to 106 viable cells/cm3. The culturable forms are so far represented by four novel genera within the Gammaproteobacteria, including the genera Thioalkalivibrio, Thioalkalimicrobium, Thioalkalispira, and Thioalkalibacter. The latter two were only found occasionally and each includes a single species, while the former two are widely distributed in various soda lakes over the world. The genus Thioalkalivibrio is the most physiologically diverse and covers the whole spectrum of salt/pH conditions present in soda lakes. Most importantly, the dominant subgroup of this genus is able to grow in saturated soda brines containing 4 M total Na+ – a so far unique property for any known aerobic chemolithoautotroph. Furthermore, some species can use thiocyanate as a sole energy source and three out of nine species can grow anaerobically with nitrogen oxides as electron acceptor. The reductive part of the sulfur cycle is active in the anoxic layers of the sediments of soda lakes. The in situ measurements of sulfate reduction rates and laboratory experiments with sediment slurries using sulfate, thiosulfate, or elemental sulfur as

Nephrourologic malformations in Turner syndrome are frequent, its diagnosis and follow-up is important in order to diminish the morbidity of this disease. The aim of this retrospective study was to analyze the nephrourologic pathology in 72 girls with Turner syndrome followed between 1989 and 2008 at Garrahan Hospital. The prevalence of nephrourologic involvement was 33% (24 patients). The most frequent findings were urinary system malformations, isolated (10 pacientes, 42%) or associated with renal malformations (9 patients, 37%); 5 patients (21%) had only renal malformations. Fifty percent of patients developed complications (8 urinary tract infection, 2 proteinuria and 2 arterial hypertension); however, none progressed to chronic renal failure. The prevalence of nephrourologic involvement was 33% and a half of these girls developed complications, our findings show the need of routine nephrological follow-up of girls with Turner syndrome and nephrourologic malformations.

Microorganisms of the genera Corynebacterium, specie pseudodiphtheriticum are a part of the indigenous microbiota of human skin and oropharinx. Nevertheless in recent decades these bacilli are emerging as opportunistic pathogens causing clinically significant infections in patients with previous compromise. We report the case of a 76 years old female patient, with a history of hypertension, hypothyroidism, type 2 diabetes and chronic renal failure, who presented pneumonia during their stay at the intensive care unit. The induced sputum revealed a representative sample with monomicrobial gram positive pleomorphic coryneform rods (Gram stain) and cultures demonstrated the presence of C. pseudodiphtheriticum as the only bacteria recovered. The pacient received an empirical third generation cephalosporin medication with a succesfull recovery. Copyright © 2016 Asociación Argentina de Microbiología. Publicado por Elsevier España, S.L.U.

The goal of this study was to accomplish the cross-cultural adaptation of a quality of life instrument, specific for neurosurgical patients, called Innsbruck Health Dimensions Questionnaire for Neurosurgical Patients (IHD-NS). Thirty patients participated in this study, male and female, all having been submitted to brain tumor surgery more than twelve months before, and whose ages ranged from 26 to 66. After the process of translation/back translation and the elaboration of the Brazilian version of the instrument, the patients were assessed and reassessed within a one-month period. Statistical analyses evinced the preservation of the internal consistency, high agreement levels and highly significant intra-class correlation, allowing for the belief in the quality and reliability of the Portuguese version, named Questionário de Dimensões de Saúde para Pacientes Neurocirúrgicos de Innsbruck--DSI (NC).
