Dominant and Recessive RYR1 Mutations in Adults with Core Lesions and Mild Muscle Symptoms

INTRODUCTION: Ryanodine receptor gene (RYR1) mutations have been associated with central core disease (CCD), multiminicore/minicore/multicore disease (MmD), and susceptibility to malignant hyperthermia (MH). METHODS: Patients with muscle symptoms in adulthood, who had features compatible with CCD/MmD, underwent clinical, histological, and genetic (RYR1 and SEPN1 genes) evaluations. Published cases of CCD and MmD with adult onset were also reviewed. RESULTS: Eight patients fulfilled the criteria for further analysis. Five RYR1 mutations, 4 of them unreported, were detected in 3 patients. Compound heterozygosity was proven in 1 case. CONCLUSIONS: To our knowledge, this is the only report of adult onset associated with recessive RYR1 mutations and central core/multiminicores on muscle biopsy. Although adult patients with CCD, MmD, and minimally symptomatic MH with abnormal muscle biopsy findings usually have a mild clinical course, differential diagnosis and carrier screening is crucial for prevention of potentially life-threatening reactions to general anesthesia.

The impact of Ireland’s current Mental Health Policy on the profile of community mental Health Services

RESUMO: Em 2006, foi aprovada uma nova política governamental para a saúde mental intitulada “Uma Visão para a Mudança”, a qual está neste momento no sétimo ano de implementação. A política descreve um enquadramento para o desenvolvimento e promoção da saúde mental positiva para toda a Comunidade e para a prestação de serviços acessíveis, baseados na comunidade, serviços especializados para pessoas com doença mental. A implementação da política e o tornar a “Vision for Change” uma realidade têm sido problemáticos, com críticas consideráveis por parte dos intervenientes, relativas à lenta e desconexa implementação. Este estudo fornece informação sobre as características dos serviços de três importantes tipos de instituições de saúde mental comunitária a nível nacional, nomeadamente Hospitais de Dia, Centros de Dia e residências comunitárias operantes 24 horas. A pesquisa analisa objetivos e funções, perfis dos pacientes, atividades terapêuticas, a eficácia das redes de comunicação e beneficia da perspectiva dos funcionários sobre o que mudou no terreno ao longo dos últimos sete anos. As questões identificadas a partir das características dos três serviços dizem respeito a todos. Os participantes indicaram que o ethos da recuperação parece ter alcançado um papel mais central no tratamento do paciente na comunidade mas reconheceram que o desafio de integrar os princípios de recuperação na prática clínica se mantém presente. Parece ser reconhecida a importância da planificação do cuidado individual nos serviços comunitários e os entrevistados indicaram que existe um empenho para garantir o envolvimento do usuário do serviço. Há diferenças entre os „pontos de vista do pessoal‟ e os „pontos de vista dos representantes‟ sobre uma série de aspetos da prestação de serviços. Este é o primeiro estudo irlandês deste género a examinar a prestação de serviços das três principais instituições comunitárias de saúde mental num só estudo. Estes serviços representam um enorme investimento em recursos, quer a nível monetário, quer humano. O estudo examinou os desafios e as questões fundamentais que lhe são aplicáveis e que têm impacto nestes três tipos de prestação de serviços. Também forneceu informações sobre os elementos de mudança positiva, os quais se começam a focar lentamente na prestação do serviço, assim como na importância da centralidade do utilizador do serviço e na promoção de um ethos da recuperação.----------ABSTRACT: In 2006, a new Government policy for mental health “A Vision for Change” was endorsed and is currently in the seventh year of implementation. The policy describes a comprehensive framework for building and fostering positive mental health across the entire community and for providing accessible, community based, specialist services for people with mental illness. The implementation of the policy and turning “Vision for Change” into reality has been problematic with considerable criticism from stakeholders concerning slow and disjointed implementation. This study provides information on three key community mental health service settings, namely Day Hospitals, Day Centres and 24 Hour Community Residences at a national level. The research looks at aims and functions, patient profiles, therapeutic activities, effectiveness of key communication networks and gains an insight from staff on what has changed on the ground over the past seven years. Issues identified from the three service settings pertain to all. Participants indicated that the recovery ethos appears to have moved to a more central role in patient care in the community but acknowledged that the challenge of integrating recovery principles in clinical practice remains present. The importance of individual care planning appears to be recognised in community services and respondents indicated that efforts are being made to ensure service user involvement. There were differences between „staff views‟ and „advocate views‟ on a number of aspects of service provision. This is the first Irish study of its kind to examine service provision across the three main community mental health settings in one study. These services represent a huge investment in resources both on a monetary and human level. This study has examined the challenges and key issues which are applicable and impacting on all three types of service provision. It has also provided information on the elements of positive change, which are slowly embedding themselves in service provision such as the importance of the centricity of the service user and the promotion of a recovery ethos.

Preliminary study of community-acquired Staphylococcus aureus infection in Manaus Hospital, Amazonia Region, Brazil

Methicillin resistant Staphylococcus aureus is considered a public health problem with a strong potential for dissemination and high rates of morbidity and mortality. In this study we describe bacteriological and epidemiological characteristics of Staphylococcus aureus in Manaus (Amazon region). During the one-year study period (2000-2001), sixteen cases of acute pyogenic multiple abscess were evaluated. Community-acquired S. aureus was identified as causative agent in 10 (62.5%) patients. The strains tested with antimicrobials by discs diffusion method, exhibited a high rate of sensitivity to cephalexin (100%), erythromycin (90%). Oxacillin-susceptible Staphylococcus aureus was 90%. No isolate was resistant to Vancomycin. To our knowledge, no series of community-acquired Staphylococcus aureus in Manaus hospital has been published. Our partial results showed a high rate of antimicrobial sensitivity among community-acquired Staphylococcus aureus in the hospital of Tropical Medicine Institute of Manaus, Amazon Region.

Prevalência de genótipos e de mutantes pré-core A-1896 do vírus da hepatite B e suas implicações na hepatite crônica, em uma população da Amazônia oriental

A infecção pelo virus da hepatite B apresenta amplo espectro de manifestações clínicas. Objetivando conhecer os genótipos do HBV mais prevalentes e determinar a ocorrência da mutação pré-core A-1896, em uma população da Amazônia oriental, correlacionando com o diagnóstico clínico, foram selecionados 51 pacientes portadores crônicos de HBsAg e HBV-DNA positivos e divididos em três grupos: grupo A (n=14, pacientes assintomáticos); grupo B (n=20, sintomáticos HBeAg positivos) e grupo C (n=17, sintomáticos HBeAg negativos), sendo usado o sequenciador automático ABI modelo 377 para identificação de genótipos e mutantes pré-core. Os resultados evidenciaram o genótipo A como o mais prevalente, 81,8%, 89,5% e 93,7%, nos grupos A, B e C, respectivamente. A mutação pré-core A-1896 foi encontrada em 11,5% (3/26), sendo todos assintomáticos. Concluiu-se que na população estudada o genótipo A foi o mais prevalente e houve baixa ocorrência do mutante pré-core A-1896, ambos não se constituindo fatores agravantes da doença hepática.

Enrichment of a PHA producing microbial community in a continuous bioreactor setup

Polyhydroxyalkanoates (PHAs) are biosynthetic polyesters, biodegradable and biocompatible making them of great interest for industrial purposes. The use of low value substrates with mixed microbial communities (MMC) is a strategy currently used to decrease the elevated PHA production costs. PHA production process requires an important step for selection and enrichment of PHA-storing microorganisms which is usually carried out in a Sequencing Batch Reactor (SBR). The aim of this study was to optimize the PHA accumulating culture selection stage using a 2-stage Continuous Stirrer Tank Reactor (CSTR) system. The system was composed by two separate feast and famine bioreactors operated continuously, mimicking the feast and famine phases in a SBR system. Acetate was used as carbon source and biomass seed was highly enriched in Plasticicumulans acidivorans obtained from activated sludge. The system was operated under two different sets of conditions (setup 1 and 2), maintaining a system total retention time of 12 hours and an OLR of 2.25 Cmmol/L.h-1. An average PHB-content of 3.3 % wt was obtained in setup 1 and 4.8% wt in setup 2. Several other experiments were performed in order to better understand the continuous system behaviour, using biomass from the continuous system. With the fed-batch experiment a maximum of 8.1% PHB was stored and the maximum substrate uptake and specific growth rates obtained in the growth experiment (1.15 Cmol Cmol-1.h-1 and 0.53 Cmol Cmol-1.h-1) were close to the ones from continuous system (1.12 Cmol Cmol-1.h-1 and 0.59 Cmol Cmol-1.h-1). The microbial community was characterized trough microscopic visualization, Denaturing Gradient Gel Electrophoresis (DGGE) analysis and Fluorescent in situ hybridization (FISH). The last studied performed mimicked the continuous system by building up a SBR system with all the same operational conditions while adding an extra acetate dosage during the 12 h cycle, simulating the substrate passing from the feast to the famine reactors under continuous operation. It was shown that possibly the continuous system was not able to efficiently select for PHB storing organisms under the operational conditions imposed, although the selected culture was capable of consuming the substrate and grow fast. This main conclusion might have resulted from two major factors affecting the system performance: the ammonium concentration in the Feast reactor and the amount of substrate leaching from the Feast to the Famine reactor.

O contributo da farmácia comunitária no envelhecimento ativo

RESUMO: A população mundial está a envelhecer de forma sustentada. O setor das farmácias em Portugal está a passar por um conjunto de alterações que conduzirá a uma ação mais interventiva ao nível da prestação de cuidados de saúde. Deste modo delineou-se um estudo descritivo, transversal e exploratório sem intervenção, de carácter qualitativo e quantitativo que compara diferentes grupos etários com o objectivo de compreender melhor o papel do farmacêutico no âmbito do envelhecimento das populações. Pretendemos assim optimizar práticas e serviços que podem ser realizados nas farmácias e alertar os utentes, para gerir melhor a sua condição de saúde, sensibilizando-os para o próprio processo de envelhecimento. Como principais resultados destacamos o papel de intervenção crucial da farmácia, quer pela sua acessibilidade quer pela contribuição que pode ter para a condição de saúde das populações. Pela amostra estudada em 100% das farmácias são feitos despistes e controlo da hipertensão arterial e hipercolesterolemia, factores fundamentais no controlo da aterosclerose e das doenças cardiovasculares. Podemos ainda concluir que a farmácia pode ser o elemento de otimização, revisão e reconciliação das terapêuticas dos resistentes em lares e ao domicílio, junto da população 65+. Em termos das pessoas idosas, o nosso estudo indicia que, apesar da crise sócio económica dos últimos anos, continuam a tomar os medicamentos mais essenciais, o que se relaciona com a política do medicamento implementada. Este trabalho pretende também, contribuir para o desenvolvimento de uma rede de competências da farmácia ao nível do envelhecimento ativo, podendo ser uma oportunidade futura.--------------ABSTRACT: World population is getting older in a sustained way. Portuguese community pharmacies are going through a change process, leading to a higher intervention in healthcare delivery. The study designed is descriptive, transversal and exploratory, with no intervention, with a qualitative and quantitative component that compares different age groups. The purpose is to better understand pharmacists’ role in population aging. One of our main goals is to optimize practices and services with potential to be performed in pharmacies and aware patients to better manage their health, becoming more conscious of their aging process. As main results we highlight the intervention of pharmacies, not only by its accessibility but also sustained on the unique contribution pharmacies deliver in the best benefit of populations’ health condition. In the sample studied, 100% of pharmacies perform screening and vigilance of hypertension and hypercholesterolemia, essential for the control of atherosclerosis and cardiovascular diseases. We may also determine the importance of pharmacies intervention over therapeutics optimization, revision and reconciliation in nursing homes and in domicile, mostly focusing patients over 65. In what concerns to elderly population our study indicates that, despite social and economic crises of recent years, the elderly keeps taking its essential medicines, which is related with medicines politics implemented at the present moment. This project intends to pay a relevant contribution to the development of a group of core competencies in pharmacies, related to the promotion of an active and healthy aging process, which represents an important future opportunity for Portuguese Pharmacies.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in Portugal:

Methicillin-resistant Staphylococcus aureus (MRSA), a human pathogen confined to hospitals (HAMRSA) for over 30 years have been emerging worldwide in the last two decades as a leading cause of severe infections in healthy individuals in the community (CA-MRSA). Despite its clinical significance, in the beginning of our studies no information existed on the prevalence, and population structure of CA-MRSA in Portugal. Moreover, it remained to be clarified how CA-MRSA emerged in our country. In particular, it was not known if CA-MRSA emerged locally by acquisition of the staphylococcal cassette chromosome mec (SCCmec) by established methicillin-susceptible S. aureus (MSSA) in the community, if they were imported from abroad or have escaped from the hospital.(...)

Integrated care approaches and skills mix policies in Europe

ABSTRACT - Background: Integration of health care services is emerging as a central challenge of health care delivery, particularly for patients with elderly and complex chronic conditions. In 2003, the World Health Organization (WHO) already began to identify it as one of the key pathways to improve primary care. In 2005, the European Commission declared integrated care as vital for the sustainability of social protection systems in Europe. Nowadays, it is recognized as a core component of health and social care reforms across European countries. Implementing integrated care requires coordination between settings, organizations, providers and professionals. In order to address the challenge of integration in such complex scenario, an effective workforce is required capable of working across interdependent settings. The World Health Report 2006 noted that governments should prepare their workforce and explore what tasks the different levels of health workers are trained to do and are capable of performing (skills mix). Comparatively to other European countries, Portugal is at an early stage in what integrated care is concerned facing a growing elderly population and the subsequent increase in the pressure on institutions and professionals to provide social and medical care in the most cost-effective way. In 2006 the Portuguese government created the Portuguese Network for Integrated Care Development (PNICD) to solve the existing long-term gap in social support and healthcare. On what concerns health workforce, the Portuguese government already recognized the importance of redefine careers keeping professional motivation and satisfaction. Aim of the study: This study aims to contribute new evidence to the debate surrounding integrated care and skills mix policies in Europe. It also seeks to provide the first evidence that incorporates both the current dynamics of implementing integrated care in Portugal and the developments of international literature. The first ambition of our study is to contribute to the growing interest in integrated care and to the ongoing research in this area by identifying its different approaches and retrieve a number of experiences in some European countries. Our second goal of this research is to produce an update on the knowledge developed on skills mix to the international healthcare management community and to policy makers involved in reforming healthcare systems and organizations. To better inform Portuguese health policies makers in a third stage we explore the current dynamics of implementing integrated care in Portugal and contextualize them with the developments reported in the international literature. Methodology: This is essentially an exploratory and descriptive study using qualitative methodology. In order to identify integrated care approaches in Europe, a systematic literature review was undertaken which resulted in a paper published in the Journal of Management and Marketing in Health care titled: Approaches to developing integrated care in Europe: a systematic literature review. This article was recommended and included into a list of references identified by The King's Fund Library. A second systematic literature review was undertaken which resulted in a paper published in the International Journal of Healthcare Management titled: Skills mix in healthcare: An international update for the management debate. Semi-structured interviews were performed on experts representing the regional coordination teams of the Portuguese Network for Integrated Care Development. In a last stage a questionnaire survey was developed based on the findings of both systematic literature reviews and semi-structured interviews. Conclusions: Even though integrated care is a worldwide trend in health care reforms, there is no unique definition. Definitions can be grouped according to their sectorial focus: community-based care, combined health and social care, combined acute and primary care, the integration of providers, and in a more comprehensive approach the whole health system. Indeed, models that seek to apply the principles of integrated care have a similar background and are continually evolving and depend on the different initiatives taken at national level. . Despite the fact that we cannot argue that there is one single set typology of models for integrated care, it is possible to identify and categorize some of the basic approaches that have been taken in attempts to implement integrated care according to: changes in organizational structure, workforce reconfiguring, and changes in the financing system. The systematic literature review on skills mix showed that despite the widely acknowledged interest on skills mix initiatives there is a lack of evidence on skills mix implications, constraints, outcomes, and quality impact that would allow policy makers to take sustained and evidence-based decisions. Within the Portuguese health system, the integrated care approach is rather organizational and financial, whereas little attention is given to workforce integration. On what concerns workforce planning Portugal it is still in the stage of analyzing the acceptability of health workforce skills mix. In line with the international approaches, integration of health and social services and bridging primary and acute care are the main goals of the national government strategy. The findings from our interviews clarify perceptions which show no discrepancy with the related literature but are rather scarce comparing to international experience. Informants hold a realistic but narrow view of integrated care related issues. They seem to be limited to the regional context, requiring a more comprehensive perspective. The questionnaire developed in this thesis is an instrument which, when applied, will allow policy makers to understand the basic set of concepts and managerial motivations behind national and regional integrated care programs. The instrument developed can foster evidence on the three essential components of integrated care policies: organizational, financial, and human resources development, and can give additional input on the context in which integrated care is being developed, the type of providers and organizations involved, barriers and constraints, and the workforce skills mix planning related strategies. The thesis was successful in recognizing differences between countries and interventions and the instrument developed will allow a better comprehension of the international options available and how to address the vital components of integrated care programs.

A matter of time: Phases of customer co-creation community participation and their impact on customer behavior

Despite the growing relevance of co-creating customer communities only little scientific evidence is available on their impact on transactional behavior of participants. Previous research has mostly used self-reported data or distinguished only between during and pre-community phases obtaining mixed results. However, the author proposes that co-creating community activity takes place in five distinguishable phases and changes in transactional behavior are limited to certain phases. Using 33 months of transactional data of a Dutch online auction provider a study was conducted covering all five phases of the community co-creation process from community planning over community set-up, co-development and co-testing to post-launch. The overall results indicate mixed effects of community participation on the different transactional variables during the co-creation process. Community participation had positive effects on auctions listing behavior at the community set-up, co-development and post-launch phases, whereby the number of auctions listed peaked during the community set-up phase. These results suggest that the impact on transactional behavior differs between co-creation phases and different psychological mechanism limited to certain phases might trigger the respective changes.

Community prevalence of methicillin and vancomycin resistant Staphylococcus aureus in and around Bangalore, southern India

INTRODUCTION: Staphylococcus aureus is a known colonizer in humans and has been implicated in community acquired soft tissue infections. However emergence of methicillin resistant S. aureus (MRSA) has aroused great concern worldwide. This study aimed to determine the prevalence of MRSA in the community of Bangalore, southern India. METHODS: Swabs were collected from anterior nares, forearm, dorsum and palm of the hands of 1,000 healthy individuals residing in and around Bangalore, belonging to different socioeconomic strata and age groups. RESULTS: Analysis verified that 22.5% and 16.6% of the individuals presented Staphylococcus aureus and MRSA, respectively, at any of the three sites. Vancomycin resistance was observed in 1.4% of the S. aureus isolates, which was confirmed by detection of the vanA gene. It was interesting to note that 58.8% of the children in the age group 1-5 years-old presented MRSA, the highest percentage compared to other age groups of < 1 (44.4%) year-old, 5-20 (21.7%) years-old, > 40 (11%) years-old and 20-40 (9.9%) years-old. Among the population of various socioeconomic strata, maximum MRSA colonization was observed among doctors (22.2%), followed by upper economic class (18.8%), lower economic class (17.7%), apparently healthy hospital in-patients (16.5%), nurses (16%) and middle economic class (12.5%). Most of the MRSA isolates were capsular polysaccharide antigen type 8 (57.1%). CONCLUSIONS: There is a need for continuous surveillance and monitoring of the presence of MRSA in the community and a clearer understanding of the dynamics of the spread of MRSA will assist in controlling its dissemination.

Epidemiological factors related to the transmission risk of Trypanosoma cruzi in a Quilombola community, State of Mato Grosso do Sul, Brazil

INTRODUCTION: This work was an epidemiological investigation of the risk of Trypanosoma cruzi transmission in the rural Quilombola community of Furnas do Dionízio, State of Mato Grosso do Sul, Brazil. METHODS: Of the 71 animals examined, seven were captured (two opossums, Didelphis albiventris; four rats, Rattus rattus; and one nine-banded armadillo, Dasypus novemcinctus) and 64 were domestic (one canine, Canis familiaris; five pigs, Sus scrofa; two bovines, Bos taurus; five caprines, Capra sp.; and 51 ovines, Ovis aries). Parasitological tests were performed to detect parasites in the blood and to identify the morphology of flagellates. These methods included fresh examinations, buffy coat tests and blood cultures. Molecular analysis of DNA for identification of trypanosomatids was performed by polymerase chain reaction (PCR) with primers S35 and S36. RESULTS: The parasitological tests showed flagellates in an opossum and two cattle. The molecular tests showed DNA from T. cruzi in an opossum and a pig. Triatoma sordida was the only triatomine species found in the community, and it colonized households (four specimens) and the surrounding areas (124 specimens). Twenty-three specimens tested positive for flagellates, which were subsequently identified as T. cruzi by PCR. CONCLUSIONS: Data analysis demonstrated that T. cruzi has a peridomestic life cycle that involves both domestic and wild mammals.

Investing beyond the core: The case of Soares da Costa

This study aims to analyze how Grupo Soares da Costa, a diversified group centered on construction, behaved in terms of strategy to the current crisis. More specifically, it purposes to understand why Soares da Costa was forced to abandon its strategic plan “Ambições Renovadas”, which was about diversification and internationalization, to decide to focus on it core business. This study uses a SWOT analysis, the examination of the strategic plans and annual reports and the conclusions of two interviews that were carried out. Being the construction sector such a traditional and significant sector to the Portuguese economy, it is important to understand what a company can do to overcome such circumstances. To deal with all the negative circumstances, Soares da Costa should give priority to projects that require low levels of initial capital and diversify geographically to markets with similar characteristics of Angola and Mozambique, where Soares da Costa already excels.
