Co-criação de valor do consumidor : impacto na fidelização do paciente ao médico

RESUMO - Confrontados por uma procura mais ativa e exigente e pressionados por uma maior restrição orçamental, os prestadores de saúde têm vindo a reconhecer o Marketing de Fidelização como uma solução sustentável para o seu sucesso financeiro. Assim, a autora explora como se desenvolve a cocriação de valor do consumidor no setor de saúde, nomeadamente, as interações, os atores e as atividades envolvidas na gestão e tratamento da doença. O projeto de investigação foca-se particularmente na cocriação de valor entre o médico regular e o paciente. Foi realizada uma pesquisa exploratória de natureza qualitativa. Os dados recolhidos na APDP, a uma amostra de 16 pacientes diabéticos através da técnica de entrevistas aprofundadas, revelaram que os estilos práticos de criação de valor do consumidor (CVCPS) desenvolvido por McColl-Kennedy et al. (2012) adequam-se às características desta doença. Os resultados do estudo sustentam que os pacientes com estilos práticos de cocriação de valor do consumidor “Parceria” e “Gestor de equipa” tendem a estar associados a um nível de fidelização elevado, pelo que se sugere que estes estilos sejam encorajados pelos prestadores. Em contraste, o Estilo de cocriação “Colaboração Passiva” está potencialmente associado a níveis de fidelização reduzidos, o que também sugere que a participação do paciente no seu relacionamento com o médico possa ser um fator potenciador da sua fidelização. O presente projeto de Investigação pretende ser um contributo teórico para investigação futura na área da cocriação e fidelização, com uma aplicação empírica que contribui para uma maior extensividade dos benefícios da cocriação de valor do consumidor para a Gestão em Saúde.

Co-infection and risk factors of tuberculosis in a Mexican HIV+ population

INTRODUCTION: The situation of tuberculosis (TB) is being modified by the human immunodeficiency virus (HIV), which is increasing the occurrence of new cases and the generation of drug resistant strains, affecting not only the people infected with HIV, but also their close contacts and the general population, conforming a serious public health concern. However, the magnitudes of the factors associated to this co-infection differ considerably in relation to the population groups and geographical areas. METHODS: In order to evaluate the prevalence and risk factors for the co-infection of tuberculosis (TB) in a population with human immunodeficiency virus (HIV+) in the Southeast of Mexico, we made the analysis of clinical and epidemiological variables and the diagnosis of tuberculosis by isolation of mycobacteria from respiratory samples. RESULTS: From the 147 HIV+ individuals analyzed, 12 were culture positive; this shows a prevalence of 8% for the co-infection. The only variable found with statistical significance for the co-infection was the number of CD4-T < 200 cells/mm³, OR 13 (95%, CI 2-106 vs 12-109). CONCLUSIONS: To our knowledge this is the first report describing the factors associated with tuberculosis co -infection with HIV in a population from Southern Mexico. The low number of CD4 T-cells was the only variable associated with the TB co-infection and the rest of the variables provide scenarios that require specific and particular interventions for this population group.

Co-infection Trypanosoma cruzi/HIV: systematic review (1980 - 2010)

INTRODUCTION: The co-infection Trypanosoma cruzi/HIV has been described as a clinical event of great relevance. The objective of this study wasto describe clinical and epidemiological aspects published in literature. METHODS: It is a systematic review of a descriptive nature from the databases Medline, Lilacs, SciELO, Scopus, from 1980 to 2010. RESULTS: There were 83 articles (2.8 articles/year) with a total of 291 cases. The co-infection was described in 1980 and this situation has become the defining AIDS clinical event in Brazil. This is the country with the highest number of publication (51.8%) followed by Argentina (27.7%). The majority of cases are amongst adult men (65.3%) native or from endemic regions with serological diagnosis in the chronic stage (97.9%) and indeterminate form (50.8%). Both diseases follow the normal course, but in 41% the reactivation of the Chagas disease occurs. The most severe form is the meningoencephalitis, with 100% of mortality without specific and early treatment of the T. cruzi. The medication of choice was the benznidazole on doses and duration normally used for the acute phase. The high parasitemia detected by direct or indirect quantitative methods indicated reactivation and its elevation is the most important predictive factor. The lower survival rate was related to the reactivation of the Chagas disease and the natural complications of both diseases. The role of the antiretroviral treatment on the co-infection cannot yet be defined by the knowledge currently existent. CONCLUSIONS: Despite the relevance of this clinical event there are still gaps to be filled.

Board independence and innovation

Legislation introduced in the U.S. in 2002/2003 significantly changed board composition of public firms by imposing a 50% independent directors’ ratio. Research on the effect of independent directors is not consensual, implying that this exogenous shock is a unique opportunity to study their importance. This study answers the question of whether or not independent directors can effectively mitigate agency conflicts between shareholders and the management, having a positive impact on the choice of successful R&D projects. We find that an increase of board independence has a positive impact on patent counts. Hence, the results support that independent directors truly spur innovation and risk taking.

Overcoming the “European Paradox”: The role of Regional Innovation Systems (RIS) in translating R&D investments into economic and employment growth

The emergence of the so-called “European Paradox” shows that R&D investment is not maximally effective and that increasing the scale of public R&D expenditures is not sufficient to generate employment and sustained economic growth. Increasing Governmental R&D Investment is far from being a “panacea” for stagnant growth. It is worth noting that Government R&D Investment does not have a statistically significant impact on employment, indicating the need to assess the trade-offs of policies that could lead to significant increases in government expenditure. Surprisingly, Governmental R&D Employment does not contribute to “mass-market” employment, despite its quite important role in reducing Youth-Unemployment. Despite the negative side-effects of Governmental R&D Employment on both GVA and GDP, University R&D Employment appears to have a quite important role in reducing Unemployment, especially Youth-Unemployment, while it also does not have a downside in terms of economic growth. Technological Capacity enhancement is the most effective instrument for reducing Unemployment and is a policy without any downside regarding sustainable economical development. In terms of wider policy implications, the results reinforce the idea that European Commission Research and Innovation policies must be restructured, shifting from a transnational framework to a more localised, measurable and operational approach.

Cutaneous and visceral leishmaniasis co-infection in dogs from Rio de Janeiro, Brazil: evaluation by specific PCR and RFLP-PCR assays

Introduction During a diagnostic evaluation of canine visceral leishmaniasis (VL), two of seventeen dogs were found to be co-infected by Leishmania (Viannia) braziliensis and Leishmania (Leishmania) chagasi. Methods Specific polymerase chain reaction (PCR) and restriction fragment length polymorphism-PCR (RFLP-PCR) assays were performed. Results PCR assays for Leishmania subgenus identification followed by RFLP-PCR analysis in biopsies from cutaneous lesions and the spleen confirmed the presence of Leishmania (Viannia) braziliensis and Leishmania (Leishmania) chagasi in those fragments. Conclusions This report reinforces the importance of using serological and molecular techniques in the epidemiological surveillance of canine populations in endemic areas in which both diseases are known to co-exist. In such cases, a reassessment of the control measures is required.

Molecular characterization of Torque teno virus and SEN virus co-infection with HIV in patients from Southern Iran

Introduction Torque teno virus (TTV) and SEN virus are circular single-stranded DNA viruses that cause blood-borne infections. The SEN virus (SEN-V) was originally detected in the serum of an injection drug user infected with human immunodeficiency virus (HIV). Recently TTV was discovered as a potential causative agent of non-A-E hepatitis. The aim of this study was to investigate the prevalence of the SEN-V-D/H and TTV in HIV patients and healthy blood donors in Iran. Methods One hundred and fifty HIV patients with a mean age of 50.46 ± 18.46 years and 150 healthy blood donors with a mean age of 48.16 ± 13.73 years were included in this study. TTV and SEN-V were detected by the PCR and were quantitatively assayed by competitive PCR (nested and semi-nested PCR). Restriction fragment length polymorphisms (RFLPs) were used to determine the heterogeneity of TTV. Results TTV and SEN-V were detected 96 (64%) and 84 (56%) of 150 HIV patients respectively. These rates were 34% (n=51) and 37.33% (n=56) in healthy blood donors (significant, p<0.05). PCR detected SEN-V/TTV DNA from 32 of the healthy blood donors (21.33%), while 65 (43.33%) of HIV patients were positive for SEN-V/TTV DNA. Of 150 HIV patients, 32.66% and 23.33% were positive for SEN-V-H and SEN-V-D, respectively and 18.66% (n=28) were co-infected with SEN-V-D/H. Conclusions The prevalence of SEN-VD/H and TTV is higher in HIV patients than in healthy blood donors in Southern Iran. Our results suggest that TTV and SEN-V might play a role in the development of liver disease in patients with immunodeficiency diseases.

Leishmania, Babesia and Ehrlichia in urban pet dogs: co-infection or cross-reaction in serological methods?

INTRODUCTION: The present study was designed to assess the occurrence of co-infection or cross-reaction in the serological techniques used for detecting the anti-Leishmania spp., -Babesia canis vogeli and -Ehrlichia canis antibodies in urban dogs from an area endemic to these parasites. METHODS: The serum samples from dogs were tested for the Babesia canis vogeli strain Belo Horizonte antigen and Ehrlichia canis strain São Paulo by immunofluorescence antibody test (IFAT) and by anti-Leishmania immunoglobulin G (IgG) antibody detection to assess Leishmania infection. We used the following four commercial kits for canine visceral leishmaniasis: ELISA, IFAT, Dual Path Platform (DPP) (Bio Manguinhos(r)/FIOCRUZ/MS) and a rK39 RDT (Kalazar Detect Canine Rapid Test; Inbios). RESULTS : Of 96 serum samples submitted to serological assays, 4 (4.2%) were positive for Leishmania as determined by ELISA; 12 (12.5%), by IFAT; 14 (14.6%) by rK39 RDT; and 20 (20.8%), by DPP. Antibodies against Ehrlichia and Babesia were detected in 23/96 (23.9%) and 30/96 (31.2%) samples, respectively. No significant association was identified between the results of tests for detecting Babesia or Ehrlichia and those for detecting Leishmania (p-value>0.05). CONCLUSIONS: In the present study, we demonstrated co-infection with Ehrlichia or Babesia and Leishmania in dogs from Minas Gerais (Brazil); we also found that the serological tests that were used did not cross-react.

Measuring impact with the social return on investment: the case of the social innovation hub

There is a growing interest in social impact assessment across the private, the public and the nonprofit sector. However, there is still limited academic research produced in this area, particularly in what concerns to the application of the Social Return of Investment (SROI) methodology. The goal of this Work Project is to give an overview of the social impact measurement literature and apply the Social Return on Investment, a flagship methodology to measure impact, to the specific case of the Social Innovation Hub (SIH). The findings suggest that each 1€ invested on the SIH generates 1,21€ in terms of social value. While this value seems very appealing to use, there are some risks in monetizing impact in such way, mainly due to the lack of reliable data available for benchmarking purposes.

Estudo de viabilidade da valorização de resíduos da cultura do arroz por co-pirólise e co-gasificação para a produção de energia renovável

Anualmente, milhares de toneladas de resíduos agrícolas são gerados no mundo, sendo a cultura do arroz uma das que mais contribui para a sua produção, especialmente com casca e palha de arroz, além dos plásticos gerados nas etapas de colheita, transporte e transformação do produto. Tradicionalmente estes resíduos são descartados ou aproveitados através de vias pouco eficientes, com consequências negativas para o ambiente. Múltiplas tecnologias têm sido estudadas e desenvolvidas para assim transformar estes resíduos em produtos de interesse: (i) gasificação, (ii) combustão e (iii) pirólise. Na presente dissertação foi avaliada a viabilidade da construção duma central de valorização de resíduos da cultura de arroz, em Portugal, através das tecnologias de co-gasificação e co-pirólise. Considerou-se que o gás de síntese, gerado na co-gasificação, é utilizado para produzir energia elétrica, e que o bio-óleo, gerado na co-pirólise, é utilizado para produzir energia elétrica ou para ser vendido a uma refinaria. A avaliação foi realizada com base no capital total de investimento, nos custos de operação e na renda gerada pela venda (i) de energia elétrica ou (ii) do bio-óleo. Com os indicadores económicos analisados, conclui-se que em Portugal nenhuma das duas tecnologias é viável, principalmente devido (i) às reduzidas quantidades de resíduos originados pela cultura de arroz neste país e (ii) aos elevados custos de transporte da matéria-prima. Caso fosse feito o aproveitamento da quantidade total de plásticos provenientes do fluxo agrícola português (4 782 t.ano-1), a construção duma central de co-pirólise seria rentável, obtendo-se uma taxa interna de rentabilidade de 69% para a venda de energia elétrica e 23,5% para venda de bio-óleo.

An atypical Toxoplasma gondii genotype in a rural Brazilian dog co-infected with Leishmania (Viannia) braziliensis

Toxoplasmosis and leishmaniasis are two worldwide zoonoses caused by the protozoan parasites Toxoplasma gondii and Leishmania spp., respectively. This report describes the clinical and laboratorial findings of a co-infection with both parasites in a 4-year-old female dog suspected of ehrlichiosis that presented anemia, thrombocytopenia, hypoalbuminemia, hyperglobulinemia, tachyzoite-like structures to the lung imprints, and polymerase chain reaction (PCR) results positive for T. gondii (kidney, lung, and liver) and Leishmania spp. Co-infection with Toxoplasma gondii and Leishmania braziliensis was confirmed by sequencing; restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) confirmed an atypical T. gondii genotype circulating in dogs that has been reported to cause human congenital toxoplasmosis.

Estudo de carbonizados resultantes da gasificação e co-pirólise de resíduos da produção e processamento de arroz. Remoção de Cr3+ presente em meio líquido

A presente dissertação apresenta o estudo de dois carbonizados, provenientes da gasificação (CG) e co-pirólise (CP) de resíduos da cultura e processamento de arroz, no processo de remoção de Cr3+ presente em meio líquido. Os materiais de partida – casca de arroz (CA) e polietileno (PE) – utilizados nos ensaios de gasificação e co-pirólise, e os carbonizados resultantes destes processos térmicos, foram caracterizados através de ensaios físicos, químicos e ecotoxicológicos. O elemento químico com maior concentração, em todos os materiais, foi o Si. Nenhum dos eluatos revelou ecotoxicidade. No estudo de remoção de Cr3+ com os dois carbonizados avaliaram-se os efeitos dos seguintes parâmetros: pH inicial da solução, massa de adsorvente, tempo de contacto e concentração inicial de Cr3+. O carbonizado que teve o melhor desempenho na remoção de Cr3+ foi o CG, com remoções de cerca de 100%, devido ao aumento de pH, que provocou a precipitação do Cr. A capacidade de adsorção deste carbonizado variou entre 12 e 26 mg Cr3+.mg-1 CG, para uma concentração inicial aproximada de Cr3+ de 50 mg.L-1, pH inicial de 5, tempo de contacto de 24 horas e razões L/S entre 800 e 1000 mL. g-1. Foram aplicados os modelos cinéticos de pseudo-primeira ordem e pseudo-segunda ordem, e as isotérmicas de Langmuir, Freundlich e Sips. Observou-se um melhor ajustamento da cinética de pseudo-segunda ordem para CG. No CP verificou-se que ambos os modelos cinéticos se ajustavam aos dados experimentais. No CG observou-se que as isotérmicas de Freundlich e Sips apresentaram os melhores ajustamentos. Foi realizado um estudo dos mecanismos de adsorção para o CG e verificou-se que a troca iónica foi o fenómeno predominante. A avaliação ecotoxicológica das soluções contendo Cr, antes e após o ensaio de adsorção, indicou que o CG promoveu uma redução acentuada da ecotoxicidade das soluções até um nível não detetável.
