ABSTRACT

Environmental enrichment is used to provide well-being to the animals, such as fish, in captive conditions, mimicking their natural habitat. It may influence fish behavior, physiology, and survival. In terms of reproduction, however, the relationship between environment enrichment and successful reproduction in captivity is still poorly explored in fish species. Aiming to understand any possible benefits of structural enrichment on fish reproduction, 10-days-hatched larvae of the twospot astyanax Astyanax bimaculatus were raised for 18 weeks in tanks with different elements of structural environmental enrichment (PVC pipes, stones, and artificial plants). In the 5th month of life, those animals were hormonally induced to reproduce to assess gamete formation and offspring quality. Animals raised in a sterile-reared environment (non-enriched) showed earlier spawning than the enriched one, presenting significant quantities of Postovulatory follicle complexes (POCs) and cells in atresia in female ovaries, indicating possible reproductive dysfunction or stress, as well as a greater quantity of empty testicular lumen in males, indicating great release of sperm. On the contrary, animals cultivated in enriched environments showed gonads filled with semen in males and vitellogenic oocytes in females. Furthermore, offspring from the sterile-reared group presented significant rates of larval abnormality compared to the enriched group. In conclusion, the results of this study show that environmental enrichment can interfere with the reproduction of fish in captivity, mainly by preventing early maturation of gametes, which can result in low-quality offspring and, consequently, low production of fish species.

ABSTRACT

As COVID-19 emerged as a phenomenon of the total environment, and despite the intertwined and complex relationships that make humanity an organic part of the Bio- and Geospheres, the majority of our responses to it have been corrective in character, with few or no consideration for unintended consequences which bring about further vulnerability to unanticipated global events. Tackling COVID-19 entails a systemic and precautionary approach to human-nature relations, which we frame as regaining diversity in the Geo-, Bio-, and Anthropospheres. Its implementation requires nothing short of an overhaul in the way we interact with and build knowledge from natural and social environments. Hence, we discuss the urgency of shifting from current to precautionary approaches to COVID-19 and look, through the lens of diversity, at the anticipated benefits in four systems crucially affecting and affected by the pandemic: health, land, knowledge and innovation. Our reflections offer a glimpse of the sort of changes needed, from pursuing planetary health and creating more harmonious forms of land use to providing a multi-level platform for other ways of knowing/understanding and turning innovation into a source of global public goods. These exemplary initiatives introduce and solidify systemic thinking in policymaking and move priorities from reaction-based strategies to precautionary frameworks.

ABSTRACT

BACKGROUND: Respiratory symptoms after exercise are frequently reported by asthmatic patients, and exercise-induced bronchoconstriction (EIB) is a frequent cause, which requires objective testing for diagnosis. Eucapnic voluntary hyperpnea (EVH) is recommended as a surrogate stimulus for this purpose. Its short-term reproducibility is not yet established in children and young adolescents with asthma. OBJECTIVE: To evaluate the short-term test-retest agreement and reproducibility of FEV1 changes after EVH in this population. METHODS: Asthmatic patients aged between 10 and 20 years underwent EVH for EIB diagnosis on two occasions 2-4 days apart at a specialized university clinic. FEV1 was measured at 5, 15, and 30 min after EVH with a target ventilation rate 21 times the baseline FEV1 . EIB was diagnosed as a decrease ≥10% in FEV1 from baseline. RESULTS: A total of 26 of 62 recruited individuals tested positive for EIB on both visits (positive group) and 17 on one visit only (divergent group), while 19 tested negative on both visits (negative group). The overall agreement was 72.5% (95%CI 61.6%, 83.6%), and Cohen's kappa coefficient was 0.452. Low bias (0.87%) and high intra-class correlation coefficient (0.854, 95%CI 0.758,0.912; p < .001) for FEV1 response between test days were found, but with wide limits of agreement (±20.72%). There were no differences in pre-challenge FEV1 or achieved ventilation rate between visits either between groups (p = .097 and p = .461) or within groups (p = .828 and p = .780). There were no safety issues. CONCLUSIONS: More than one EVH test should be performed in children and young adolescents with asthma to exclude EIB and minimize misdiagnosis and mistreatment.

ABSTRACT

Healthcare workforce shortage can be compensated by using information and communication technologies. Remote patient monitoring systems allow us to identify and communicate complications and anomalies. Integrating social networking services into remote patient monitoring systems enables users to manage their relationships. User defined relationships may be used to disseminate healthcare related notifications. Hence this integration leads to quicker interventions and may reduce hospital readmission rate. As a proof of concept, a module was integrated to a remote patient monitoring platform. A mobile application to manage relationships and receive notifications was also developed.

ABSTRACT

Analyzing human pupillary behavior is a non-invasive method for evaluating neurological activity. This method contributes to the medical field because changes in pupillary behavior can be correlated with several health conditions such as Parkinson, Alzheimer, autism and diabetes. Analyzing human pupillary behavior is simple and low-cost, and may be used as a complementary diagnosis. Therefore, this work aims to develop an automated system to evaluate human pupillary behavior. The solution consists of a portable recording device, a pupillometer; integrated with a recording and evaluation software based on computer vision. The system is able to stimulate, record, measure and extract relevant features of human pupillary behavior. The results show that the proposed system is fast and accurate, and can be used as an assessment tool for real and extensive clinical practice and research.

ABSTRACT

Este estudo analisou o bem estar psicossocial de aposentados da cidade de Goiânia. Participaram 118 homens, aposentados por tempo de serviço, cuja vida laboral ocorreu em empresas públicas, autarquias e de economia mista, de âmbito federal, estadual ou municipal. A coleta de dados foi realizada por meio de questionário com perguntas abertas e fechadas. Para a análise dos resultados foi realizada uma regressão múltipla, tendo como variável critério o índice de bem estar e, como seus possíveis preditores, oito variáveis sobre aspectos referentes aos relacionamentos sociais, vida financeira, avaliação da saúde e da vida sexual após a aposentadoria. As variáveis sobre o planejamento, satisfação com a saúde e as relações sociais nas quais eles possam se locomover com independência foram as mais significativas para o bem estar dos participantes. Esses resultados são discutidos ressaltando as especificidades da amostra aqui utilizada, as dificuldades de generalizações e a importância de futuros estudos objetivando tornar esse tema central na agenda de trabalhos sobre o envelhecimento populacional.

ABSTRACT

INTRODUÇÃO: A eficácia da ressecção em bloco duodenopancreático para tumores infiltrativos não periampulares ainda não está bem definida³, mas sabe-se que em tumores colorretais localmente avançados, a ressecção multivisceral é, na maioria das vezes, a chance de melhor qualidade de vida4. OBJETIVO: apresentar um caso de neoplasia de cólon direito com invasão duodenopancreática tratado com gastroduodenopancreatectomia. RELATO DE CASO: Paciente de 73 anos, branco, que há oito meses apresentava astenia, adinamia e emagrecimento de aproximadamente 20 kg. Ao exame físico: IMC: 20,3, descorado ++/4. Abdome com massa palpável em flanco direito de aproximadamente 15cm. A colonoscopia demonstrou tumor de cólon direito e o anátomo-patológico evidenciou adenocarcinoma moderadamente diferenciado. A Tomografia computadorizada demonstrou os vasos mesentéricos livres de invasão. No intra-operatório se observou massa tumoral envolvendo cólon ascendente até ângulo hepático invadindo segunda para terceira porção duodenal. Foi realizada colectomia direita associadaà gastroduodenopancreatectomia em bloco. O anátomo-patológico da peça revelou adenocarcinoma moderadamente diferenciado de intestino grosso com metástases em tecido duodenal e pancreático com infiltração angio-linfática. O paciente sobreviveu por 8 meses. CONCLUSÃO: A gastroduodenopancreatectomia deve ser considerada para tumores não periampulares na ausência de metástases à distância e quando a condição clinica do paciente permitir e foi a conduta adequada para este paciente.

ABSTRACT

Sistema Nacional de Inovação (NSI) é uma construção institucional que impulsiona o progresso científico-tecnológico em economias capitalistas modernas. A literatura sobre economia da ciência e tecnologia (C&T) permite desagregar o NSI em setores, pois a dinâmica de inovação é significativamente diferente entre eles. O objetivo deste artigo é compreender as peculiaridades da distribuição dos países em relação aos indicadores de C&T em saúdee, conseqüentemente, verificar se existe limiar de produção científica para o setor. O principal resultado do artigo é a identificação de uma descontinuidade da produção científico-tecnológica em saúde entre os países com sistemas maduros de inovação e países com sistemas imaturos.

ABSTRACT

BACKGROUND: This paper combines the literature on public health, on economics of health and on economics of technological innovation to discuss the peculiarities of labour in the health care sector. METHOD AND FRAMEWORK: The starting point is the investigation of the economic peculiarities of medical care. RESULTS AND DISCUSSIONS: This investigation leads to the identification of the prevalence of non-market forms of medical care in the countries of the Organisation for Economic Co-operation and Development (OECD). Furthermore, the health care system has a distinctive characteristic from other economic sectors: it is the intersection between social welfare and innovation systems. The relationship between technological innovation and cost in the health care sector is surveyed. Finally, the Brazilian case is discussed as an example of a developing country. CONCLUSION: The peculiarities of labour in the health care sector suggest the need to recognize the worth of sectoral labour and to cease to treat it separately. This process should take into account the rapid development of the health innovation system and one important consequence: the obsolescence of the acquired knowledge. One way to dignify labour is to implement continued education and training of health professions personnel.

ABSTRACT

O artigo avalia as características principais dos sistemas de inovação do setor saúde de países avançados como uma introdução para a discussão dos desafios e potencialidades do caso brasileiro. A importância estratégica da inovação em saúde é enfatizada, indicando tanto as interações entre a pesquisa científica e as inovações no setor como as múltiplas influências entre a construção de um efetivo sistema de inovação no setor saúde e a economia. No caso brasileiro, em que o atraso tecnológico coexiste com o atraso social, a superação de ambos passa pelo fortalecimento das instituições do sistema de inovação do setor saúde.

ABSTRACT

A motivação para esses estudos veio da constatação de que seria muito relevante para o planejamento de uma política científica nacional na área de saúde saber em que medida o investimento em pesquisa retorna à so-ciedade, ou seja, de que maneira a produção de conhecimento e a capacidade de docência e extensão, que no Brasil são intimamente associadas, estão se refletindo na sociedade. Arquivos no formato PDF, compactados no formato ZIP, requer WinZIP e Acrobat Reader.
