Feature Extraction in Densely Sensed Environments: Extensions to Multiple Broadcast Domains

The vision of the Internet of Things (IoT) includes large and dense deployment of interconnected smart sensing and monitoring devices. This vast deployment necessitates collection and processing of large volume of measurement data. However, collecting all the measured data from individual devices on such a scale may be impractical and time consuming. Moreover, processing these measurements requires complex algorithms to extract useful information. Thus, it becomes imperative to devise distributed information processing mechanisms that identify application-specific features in a timely manner and with a low overhead. In this article, we present a feature extraction mechanism for dense networks that takes advantage of dominance-based medium access control (MAC) protocols to (i) efficiently obtain global extrema of the sensed quantities, (ii) extract local extrema, and (iii) detect the boundaries of events, by using simple transforms that nodes employ on their local data. We extend our results for a large dense network with multiple broadcast domains (MBD). We discuss and compare two approaches for addressing the challenges with MBD and we show through extensive evaluations that our proposed distributed MBD approach is fast and efficient at retrieving the most valuable measurements, independent of the number sensor nodes in the network.

A 63-Year-Old Woman Presenting with a Synovial Sarcoma of the Hand: a Case Report

INTRODUCTION: Synovial sarcoma is a high-grade, soft-tissue sarcoma that most frequently is located in the vicinity of joints, tendons or bursae, although it can also be found in extra-articular locations. Most patients with synovial sarcoma of the hand are young and have a poor prognosis, as these tumors are locally aggressive and are associated with a relatively high metastasis rate. According to the literature, local recurrence and/or metastatic disease is found in nearly 80% of patients. Current therapy comprises surgery, systemic and limb perfusion chemotherapy, and radiotherapy. However, the 5-year survival rate is estimated to be only around 27% to 55%. Moreover, most authors agree that synovial sarcoma is one of the most commonly misdiagnosed malignancies of soft tissues because of their slow growing pattern, benign radiographic appearance, ability to change size, and the fact that they may elicit pain similar to that caused by common trauma. CASE PRESENTATION: We describe an unusual case of a large synovial sarcoma of the hand in a 63-year-old Caucasian woman followed for 12 years by a multidisciplinary team. In addition, a literature review of the most pertinent aspects of the epidemiology, diagnosis, treatment and prognosis of these patients is presented. CONCLUSION: Awareness of this rare tumor by anyone dealing with hand pathology can hasten diagnosis, and this, in turn, can potentially increase survival. Therefore, a high index of suspicion for this disease should be kept in mind, particularly when evaluating young people, as they are the most commonly affected group.

O presente relatório de estágio incide sob a experiência profissional adquirida no âmbito do estágio realizado no Serviço de Auditoria Interna da Unidade Local de Saúde de Matosinhos, Entidade Pública Empresarial (EPE), com vista à conclusão do mestrado em auditoria. O estágio teve como intuito poder observar, aprender e integrar o dia-a-dia de trabalho do Serviço de Auditoria Interna na entidade de acolhimento. O relatório tem uma componente teórica, onde se pretende dar uma breve visão sobre a auditoria interna, controlo interno e gestão de risco, e uma componente prática onde se descrevem as atividades realizadas. O estágio teve como objetivo a aplicação prática dos conhecimentos teóricos adquiridos ao longo do ciclo de estudos, onde foram absorvidos conceitos e técnicas, mas que só na prática se consegue uma real demostração da sua funcionalidade. A atividade de estágio teve início a 24 Junho de 2014, tendo terminado a 21 de Junho de 2015.

Syncope and Intermittent Brugada ECG Pattern

A síndrome de Brugada é uma síndrome rara, com uma prevalência aproximada na Europa de 1-5/10 000 habitantes, mas cuja apresentação clínica inicial pode ser morte súbita. Embora com um padrão eletrocardiográfico típico, este é por vezes intermitente. Os autores apresentam o caso clínico de um doente de sexo masculino, de 32 anos, sem fatores de risco pessoais conhecidos e história familiar de morte súbita, que recorre ao Serviço de Urgência por síncope sem pródromos. O primeiro eletrocardiograma (ECG) em ritmo sinusal documenta a presença de uma elevação isolada e inespecífica do segmento ST em V2. Da restante investigação diagnóstica realizada, salienta-se a repetição do ECG, que revelou a presença de padrão de Brugada tipo 1. Este mesmo padrão é exacerbado posteriormente numa situação de infeção respiratória. O doente foi submetido a estudo eletrofisiológico, seguido de implantação de cardiodesfibrilhador (CDI), tendo tido um episódio de fibrilhação ventricular convertido com choque via CDI 2 meses após a implantação.

Desenvolvimento de um serviço local de Saúde Mental em Famalicão

RESUMO: O desenvolvimento de serviços locais adequados deve ser baseado numa avaliação sistemática das necessidades e resultados obtidos nos cuidados a uma população de indivíduos identificados como apresentando uma doença mental na área de referenciação do serviço. Neste sentido foram utilizados os seguintes métodos: dados epidemiológicos acerca das necessidades locais e taxas de utilização de serviços a nível nacional e local, este último com base no case-register. Os diagnósticos de maior prevalência em ambulatório são as perturbações de humor e as perturbações neuróticas de stress ou somatoformes, com uma preponderância de doenças mentais comuns (depressão e ansiedade) em serviços de psiquiatria. Constatam-se baixas taxas de abandono da consulta (12%). A idade, a doença e a escolaridade estão correlacionados com o risco de drop-out, mas utilizada a regressão logística, a idade e a escolaridade perdem o seu significado estatístico. Encontram-se taxas reduzidas de drop-out dos indivíduos com psicose ou perturbações bipolares, em virtude da intervenção activa da equipa. Os custos de transporte, a distância ao local de consulta e o tempo de espera para a primeira consulta são barreiras no acesso aos cuidados a nível local. Os cuidadores não se sentem apoiados pela rede de suporte social e queixam-se sobretudo da acessibilidade, mas exibem elevadas taxas de satisfação com os serviços prestados. Decidiu-se apostar numa organização do serviço baseada na comunidade, com intervenções baseadas na evidência, dando prioridade ao doente mental grave e à qualidade dos cuidados.----------- ABSTRACT: The development of appropriate local services should be based on a systematic assessment of the needs and outcomes of the population of individuals identified as mentally ill within the service’s catchment area. A number of methods may be used as proxies in assessing local needs for services, such as service utilization rates found nationally and locally, by case-register. The most prevalent diagnoses in ambulatory care are mood disorders and neurotic, stress and somatoform disorders, with a majority of common mental disorders (depression and anxiety) in psychiatric services. Low dropout rates (12%) are found in ambulatory care. Age, disease and education are correlated with the risk of drop-out, but after using logistic regression, age and education lose their statistical significance. Low drop-out rates are found in individuals with psychosis or bipolar disorders, because the active intervention from the team. The costs of transportation, distance and the waiting time for the first consultation are barriers in access of care locally. Carers do not feel supported by the network of social support and complain primarily of accessibility, but exhibit high levels of satisfaction with the services provided. It was decided to invest in a service organization based in the community with evidence-based interventions, giving priority to severe mental illness and quality of care.

In vitro PHYTOTHERAPY OF VECTOR SNAILS BY BINARY COMBINATIONS OF LARVICIDAL ACTIVE COMPONENTS IN EFFECTIVE CONTROL OF FASCIOLIASIS

SUMMARY A food-borne trematode infection fascioliasis is one among common public health problems worldwide. It caused a great economic loss for the human race. Control of snail population below a certain threshold level is one of the important methods in the campaign to reduce the incidence of fascioliasis. The life cycle of the parasite can be interrupted by killing the snail or Fasciola larva redia and cercaria inside of the snail Lymnaea acuminata. In vitro toxicity of different binary combinations (1:1 ratio) of plant-derived larvicidal active components such as citral, ferulic acid, umbelliferone, azadirachtin and allicin against Fasciola redia and cercaria were tested. The mortality of larvae was observed at 2h, 4h, 6h and 8h of treatment. In in vitro condition azadirachtin + allicin (1:1 ratio) was highly toxic against redia and cercaria (8h LC50 0.006 and 0.005 mg/L). Toxicity of citral + ferulic acid was lowest against redia and cercaria larvae.

AN UPWARD TREND IN DNA P16INK4A METHYLATION PATTERN AND HIGH RISK HPV INFECTION ACCORDING TO THE SEVERITY OF THE CERVICAL LESION

SUMMARY High-risk human papillomavirus (hr-HPV) infection is necessary but not sufficient for cervical cancer development. Recently, P16INK4A gene silencing through hypermethylation has been proposed as an important cofactor in cervical carcinogenesis due to its tumor suppressor function. We aimed to investigate P16INK4A methylation status in normal and neoplastic epithelia and evaluate an association with HPV infection and genotype. This cross-sectional study was performed with 141 cervical samples from patients attending Hospital Moncorvo Filho, Rio de Janeiro. HPV detection and genotyping were performed through PCR and P16INK4A methylation by nested-methylation specific PCR (MSP). HPV frequency was 62.4% (88/141). The most common HPV were HPV16 (37%), HPV18 (16.3%) and HPV33/45(15.2%). An upward trend was observed concerning P16INK4A methylation and lesion degree: normal epithelia (10.7%), low grade lesions (22.9%), high grade (57.1%) and carcinoma (93.1%) (p < 0.0001). A multivariate analysis was performed to evaluate an association between methylation, age, tobacco exposure, HPV infection and genotyping. A correlation was found concerning methylation with HPV infection (p < 0.0001), hr-HPV (p = 0.01), HSIL (p < 0.0007) and malignant lesions (p < 0.0001). Since viral infection and epigenetic alterations are related to cervical carcinoma, we suggest that P16INK4A methylation profile maybe thoroughly investigated as a biomarker to identify patients at risk of cancer.
