Voluntariado empresarial: uma estratégia para a sustentabilidade organizacional

A globalização, os impactos económicos, sociais e ecológicos, a alteração da relação entre as organizações e as entidades interessadas favoreceram a mudança de padrão e comportamentos organizacionais e mudaram as bases da sustentabilidade organizacional. A Responsabilidade Social Organizacional institucionalizou-se progressivamente como campo de gestão associado à transparência, ética e cidadania, geradoras de capital simbólico associado à reputação e à legitimação. Nesta reorientação estratégica da relação das organizações com o ambiente onde operam, o voluntariado empresarial aflora como um instrumento de criação de valor económico e social. Este tem amplitude interna e externa, mobilizando colaboradores, organizações e comunidades. A sua adoção tem atraído uma preferência crescente pelas pressões institucionais para a isomorfização, pela melhoria do capital social organizacional ou pelo reconhecimento das vantagens económicas inerentes. Muito embora as motivações sejam distintas (altruístas, ideológicas e/ou materiais), as vantagens convergem para a maximização do potencial humano dos recursos envolvidos e da sustentabilidade organizacional. Constata-se uma melhoria das atitudes face ao trabalho, por via da maior identificação com a organização e um aumento do capital social pela confiança e cooperação cívica recrutadas. O voluntariado empresarial, sempre que integrado na cadeia de valor organizacional, contribui para a sustentabilidade da organização, dado que atua como uma plataforma de oportunidades que pode ser ativada/estimulada pelos colaboradores que o desejam, pela organização que o propõe e pelas comunidades que o reclamam. Esta é uma plataforma que alcança a dimensão económica, ambiental e social e as equilibra, tomando nota das necessidades a suprir pela antevisão de novas tendências, constituindo-se assim numa vantagem competitiva e comparativa. Esta reflexão tem natureza conceptual e adota os seguintes objetivos: 1) identificar vantagens do voluntariado empresarial, enquanto gerador de ativos intangíveis, nas estratégias organizacionais; 2) problematizar a adequação de práticas de gestão de recursos humanos ao voluntariado empresarial

Responsabilidade social organizacional: a gestão filantrópica numa empresa multinacional

A responsabilidade social das organizações convida-as a não se orientarem exclusivamente por critérios economicistas, introduzindo a ética e a filantropia nas tomadas de decisão, critérios que contribuem para a sustentabilidade da organização, garantindo ativos intangíveis imprescindíveis. A filantropia continua umbilicalmente associada à responsabilidade social das organizações, podendo ser uma expressão/manifestação ou uma dimensão da responsabilidade social das organizações. A responsabilidade social e a filantropia são, por vezes, tidas como sinónimos, todavia a filantropia não pode limitar o escopo da responsabilidade social, assim como a responsabilidade social não se pode limitar à filantropia. A investigação de que daremos conta sustentou-se num estudo de caso e decorreu numa unidade fabril que integra um grupo empresarial de dimensão multinacional, cujo escopo é a produção de equipamentos tecnológicos para o setor automóvel. Recenseamos da literatura um conjunto de indicadores atinentes à filantropia para refletir sobre a diversidade de práticas filantrópicas. A filantropia granjeou atenção e esforços crescentes, justificáveis pelo contexto de crise económica e financeira que reavivou as necessidades de assistência social, estimulando ligações com a comunidade. Os dados empíricos relativos a esta dimensão de responsabilidade social organizacional serão analisados num quadro teórico composto pelos conceitos de instituição e legitimidade, da teoria institucional

Diabetes Mellitus - Estudo de AEQ dos Parâmetros Glicose e HbA1c (2008-2012)

Segundo o Internacional Diabetes Federation (IDF) (2012), a Diabetes atinge 371 milhões de pessoas em todo o mundo, correspondendo a 8,3% da população mundial. Estima-se que em cerca de 50% dessas pessoas a diabetes ainda não foi diagnosticada. Em 2012 morreram devido à diabetes 4,8 milhões de pessoas, sendo que metade tinha idade inferior a 60 anos. Segundo a IDF, Portugal posiciona-se entre os países europeus com maior taxa de prevalência de diabetes. A prevalência de diabéticos em Portugal em 2011, numa população entre os 20 e 79 anos foi de 12.7%, sendo que 7,2% diziam respeito a prevalência de diabetes diagnosticada e 5,5% a diabetes não diagnosticada. Em 2009, a percentagem de diabéticos em Portugal rondava os 11,7% e em 2010 os 12,4%. Dado a incidência a nível mundial da Diabetes Mellitus, torna-se de elevada importância avaliar toda a sua envolvência e estudar bem quais os critérios a ter em consideração. Propusemo-nos estudar os parâmetros bioquímicos relacionados com esta patologia - Glicose e Hemoglobina Glicada A1c (HbA1c), recorrendo à análise dos resultados dos últimos cinco anos (2008-2012) dos ensaios interlaboratoriais e metodologias utilizadas do Programa Nacional de Avaliação Externa da Qualidade, do Instituto Nacional de Saúde Doutor Ricardo Jorge (PNAEQ-INSA), Lisboa, Portugal

Prevalence of bovine tuberculosis and risk factor assessment in cattle in rural livestock areas of Govuro District in the Southeast of Mozambique

BACKGROUND: Bovine tuberculosis (bTB), caused by Mycobacterium bovis, is an infectious disease of cattle that also affects other domestic animals, free-ranging and farmed wildlife, and also humans. In Mozambique, scattered surveys have reported a wide variation of bTB prevalence rates in cattle from different regions. Due to direct economic repercussions on livestock and indirect consequences for human health and wildlife, knowing the prevalence rates of the disease is essential to define an effective control strategy. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional study was conducted in Govuro district to determine bTB prevalence in cattle and identify associated risk factors. A representative sample of the cattle population was defined, stratified by livestock areas (n = 14). A total of 1136 cattle from 289 farmers were tested using the single comparative intradermal tuberculin test. The overall apparent prevalence was estimated at 39.6% (95% CI 36.8-42.5) using a diagnostic threshold cut-off according to the World Organization for Animal Health. bTB reactors were found in 13 livestock areas, with prevalence rates ranging from 8.1 to 65.8%. Age was the main risk factor; animals older than 4 years were more likely to be positive reactors (OR = 3.2, 95% CI: 2.2-4.7). Landim local breed showed a lower prevalence than crossbred animals (Landim × Brahman) (OR = 0.6, 95% CI: 0.4-0.8). CONCLUSIONS/SIGNIFICANCE: The findings reveal an urgent need for intervention with effective, area-based, control measures in order to reduce bTB prevalence and prevent its spread to the human population. In addition to the high prevalence, population habits in Govuro, particularly the consumption of raw milk, clearly may potentiate the transmission to humans. Thus, further studies on human tuberculosis and the molecular characterization of the predominant strain lineages that cause bTB in cattle and humans are urgently required to evaluate the impact on human health in the region.The research leading to these results has received funding from the European Union's Seventh Framework Program (FP7/2007-2013) under grant agreement no 221948, ICONZ (Integrated Control of Neglected Zoonoses).

Calcium signaling and the novel anti-proliferative effect of the UTP-sensitive P2Y11 receptor in rat cardiac myofibroblasts

During myocardial ischemia and reperfusion both purines and pyrimidines are released into the extracellular milieu, thus creating a signaling wave that propagates to neighboring cells via membrane-bound P2 purinoceptors activation. Cardiac fibroblasts (CF) are important players in heart remodeling, electrophysiological changes and hemodynamic alterations following myocardial infarction. Here, we investigated the role UTP on calcium signaling and proliferation of CF cultured from ventricles of adult rats. Co-expression of discoidin domain receptor 2 and -smooth muscle actin indicate that cultured CF are activated myofibroblasts. Intracellular calcium ([Ca2+]i) signals were monitored in cells loaded with Fluo-4 NW. CF proliferation was evaluated by the MTT assay. UTP and the selective P2Y4 agonist, MRS4062, caused a fast desensitizing [Ca2+]i rise originated from thapsigargin-sensitive internal stores, which partially declined to a plateau providing the existence of Ca2+ in the extracellular fluid. The biphasic [Ca2+]i response to UTP was attenuated respectively by P2Y4 blockers, like reactive blue-2 and suramin, and by the P2Y11 antagonist, NF340. UTP and the P2Y2 receptor agonist MRS2768 increased, whereas the selective P2Y11 agonist NF546 decreased, CF growth; MRS4062 was ineffective. Blockage of the P2Y11receptor or its coupling to adenylate cyclase boosted UTP-induced CF proliferation. Confocal microscopy and Western blot analysis confirmed the presence of P2Y2, P2Y4 and P2Y11 receptors. Data indicate that besides P2Y4 and P2Y2 receptors which are responsible for UTP-induced [Ca2+]i transients and growth of CF, respectively, synchronous activation of the previously unrecognized P2Y11 receptor may represent an important target for anti-fibrotic intervention in cardiac remodeling

Bradykinin-induced Ca2+ signaling in human subcutaneous fibroblasts involves ATP release via hemichannels leading to P2Y12 receptors activation

Chronic musculoskeletal pain involves connective tissue remodeling triggered by inflammatory mediators, such as bradykinin. Fibroblast cells signaling involve changes in intracellular Ca2+ ([Ca2+]i). ATP has been related to connective tissue mechanotransduction, remodeling and chronic inflammatory pain, via P2 purinoceptors activation. Here, we investigated the involvement of ATP in bradykinin-induced Ca2+ signals in human subcutaneous fibroblasts. Bradykinin, via B2 receptors, caused an abrupt rise in [Ca2+]i to a peak that declined to a plateau, which concentration remained constant until washout. The plateau phase was absent in Ca2+-free medium; [Ca2+]i signal was substantially reduced after depleting intracellular Ca2+ stores with thapsigargin. Extracellular ATP inactivation with apyrase decreased the [Ca2+]i plateau. Human subcutaneous fibroblasts respond to bradykinin by releasing ATP via connexin and pannexin hemichannels, since blockade of connexins, with 2- octanol or carbenoxolone, and pannexin-1, with 10Panx, attenuated bradykinin-induced [Ca2+]i plateau, whereas inhibitors of vesicular exocytosis, such as brefeldin A and bafilomycin A1, were inactive. The kinetics of extracellular ATP catabolism favors ADP accumulation in human fibroblast cultures. Inhibition of ectonucleotidase activity and, thus, ADP formation from released ATP with POM-1 or by Mg2+ removal from media reduced bradykinin-induced [Ca2+]i plateau. Selective blockade of the ADP-sensitive P2Y12 receptor with AR-C66096 attenuated bradykinin [Ca2+]i plateau, whereas the P2Y1 and P2Y13 receptor antagonists, respectively MRS 2179 and MRS 2211, were inactive. Human fibroblasts exhibited immunoreactivity against connexin-43, pannexin-1 and P2Y12 receptor. Bradykinin induces ATP release from human subcutaneous fibroblasts via connexin and pannexin-1-containing hemichannels leading to [Ca2+]i mobilization through the cooperation of B2 and P2Y12 receptors

Histamine Induces ATP Release from Human Subcutaneous Fibroblasts, via Pannexin-1 Hemichannels, Leading to Ca2+Mobilization and Cell Proliferation

Changes in the regulation of connective tissue ATP-mediated mechano-transduction and remodeling may be an important link to the pathogenesis of chronic pain. It has been demonstrated that mast cell-derived histamine plays an important role in painful fibrotic diseases. Here we analyzed the involvement of ATP in the response of human subcutaneous fibroblasts to histamine. Acute histamine application caused a rise in intracellular Ca(2+) ([Ca(2+)]i) and ATP release from human subcutaneous fibroblasts via H1 receptor activation. Histamine-induced [Ca(2+)]i rise was partially attenuated by apyrase, an enzyme that inactivates extracellular ATP, and by blocking P2 purinoceptors with pyridoxal phosphate-6-azo(benzene-2,4-disulfonic acid) tetrasodium salt and reactive blue 2. [Ca(2+)]i accumulation caused by histamine was also reduced upon blocking pannexin-1 hemichannels with (10)Panx, probenecid, or carbenoxolone but not when connexin hemichannels were inhibited with mefloquine or 2-octanol. Brefeldin A, an inhibitor of vesicular exocytosis, also did not block histamine-induced [Ca(2+)]i mobilization. Prolonged exposure of human subcutaneous fibroblast cultures to histamine favored cell growth and type I collagen synthesis via the activation of H1 receptor. This effect was mimicked by ATP and its metabolite, ADP, whereas the selective P2Y1 receptor antagonist, MRS2179, partially attenuated histamine-induced cell growth and type I collagen production. Expression of pannexin-1 and ADP-sensitive P2Y1 receptor on human subcutaneous fibroblasts was confirmed by immunofluorescence confocal microscopy and Western blot analysis. In conclusion, histamine induces ATP release from human subcutaneous fibroblasts, via pannexin-1 hemichannels, leading to [Ca(2+)]i mobilization and cell growth through the cooperation of H1 and P2 (probably P2Y1) receptors.info:eu-repo/semantics/publishedVersio

Mycobacterium tuberculosis causing tuberculous lymphadenitis in Maputo, Mozambique

BACKGROUND: The zoonosis bovine tuberculosis (TB) is known to be responsible for a considerable proportion of extrapulmonary TB. In Mozambique, bovine TB is a recognised problem in cattle, but little has been done to evaluate how Mycobacterium bovis has contributed to human TB. We here explore the public health risk for bovine TB in Maputo, by characterizing the isolates from tuberculous lymphadenitis (TBLN) cases, a common manifestation of bovine TB in humans, in the Pathology Service of Maputo Central Hospital, in Mozambique, during one year. RESULTS: Among 110 patients suspected of having TBLN, 49 had a positive culture result. Of those, 48 (98 %) were positive for Mycobacterium tuberculosis complex and one for nontuberculous mycobacteria. Of the 45 isolates analysed by spoligotyping and Mycobacterial Interspersed Repetitive Unit - Variable Number Tandem Repeat (MIRU-VNTR), all were M. tuberculosis. No M. bovis was found. Cervical TBLN, corresponding to 39 (86.7 %) cases, was the main cause of TBLN and 66.7 % of those where from HIV positive patients. We found that TBLN in Maputo was caused by a variety of M. tuberculosis strains. The most prevalent lineage was the EAI (n?=?19; 43.2 %). Particular common spoligotypes were SIT 48 (EAI1_SOM sublineage), SIT 42 (LAM 9), SIT 1 (Beijing) and SIT53 (T1), similar to findings among pulmonary cases. CONCLUSIONS: M. tuberculosis was the main etiological agent of TBLN in Maputo. M. tuberculosis genotypes were similar to the ones causing pulmonary TB, suggesting that in Maputo, cases of TBLN arise from the same source as pulmonary TB, rather than from an external zoonotic source. Further research is needed on other forms of extrapulmonary TB and in rural areas where there is high prevalence of bovine TB in cattle, to evaluate the risk of transmission of M. bovis from cattle to humans.Swedish International Development Cooperation Agency / Department for Research Cooperation (Sida/SAREC) through Eduardo Mondlane University and Karolinska Institutet Research and Training (KIRT) collaboratio

Genetic diversity and potential routes of transmission of Mycobacterium bovis in Mozambique

CITATION: Machado, A., et al. 2018. Genetic diversity and potential routes of transmission of Mycobacterium bovis in Mozambique. PLOS Neglected Tropical Diseases, 12(1):e0006147, doi:10.1371/journal.pntd.0006147.The original publication is available at https://journals.plos.org/plosntdsBovine tuberculosis is a zoonotic disease with largely unknown impact in Africa, with risk factors such as HIV and direct contact with animals or consumption of Mycobacterium bovis infected animal products. In order to understand and quantify this risk and design intervention strategies, good epidemiological studies are needed. Such studies can include molecular typing of M. bovis isolates. The aim of this study was to apply these tools to provide novel information concerning the distribution of bovine tuberculosis in cattle in Mozambique and thereby provide relevant information to guide policy development and strategies to contain the disease in livestock, and reduce the risk associated with transmission to humans. A collection of 178 M. bovis isolates was obtained from cattle in Mozambique. Using spoligotyping and regions of difference analysis, we classified the isolates into clonal complexes, thus reporting the first characterisation of M. bovis strains in this region. Data from MIRU-VNTR typing was used to compare isolates from a number of African countries, revealing a deeply geographically structured diversity of M. bovis. Eastern Africa appears to show high diversity, suggesting deep evolution in that region. The diversity of M. bovis in Africa does not seem to be a function of recent importation of animals, but is probably maintained within each particular region by constant reinfection from reservoir animals. Understanding the transmission routes of M. bovis in Mozambique and elsewhere is essential in order to focus public health and veterinary resources to contain bovine tuberculosis.https://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0006147Publisher's versio
