Effect of feeding frequency on the reproductive efficiency of two species of Triatoma with different epidemiological importance

Introduction In Triatominae, reproductive efficiency is an important factor influencing population dynamics, and a useful parameter in measuring a species' epidemiological significance as a vector of Trypanosoma cruzi (Chagas, 1909). The reproductive efficiency of triatomines is affected by food availability; hence, we measured and compared the effects of feeding frequency on the reproductive parameters of Triatoma patagonica (Del Ponte, 1929) and Triatoma infestans (Klug, 1934), and the effects of starvation on T. patagonica. Methods Couples from both species were fed weekly, or every 3 weeks; in addition, females in couples of T. patagonica were not fed. Each couple was observed weekly and reproductive efficiency was assessed on the following parameters: fecundity (eggs/female), fertility (eggs hatched/eggs laid), initiation and end of oviposition, initiation of mating, number of matings/week, and number of reproductive weeks. Relative meal size index (RMS), blood consumption index (CI), and E values (eggs/mg blood) were also calculated. Results Changes in feeding frequency affected the reproductive parameters of T. patagonica only, with a decrease in fecundity and number of reproductive weeks for those fed every 3 weeks, or not fed. The reproductive period, RMS index, and CI were lower for T. patagonica than T. infestans. However, despite the lower fecundity of T. patagonica, this species required less blood to produce eggs, with an E values of 2 compared to 2.94 for T. infestans. Conclusions Our results suggest that the differences in fecundity observed between species reflect the availability of food in their natural ecotopes.

How to engage low category users through social media- The case of the make-up sector in Portugal

Purpose: This work project should be inevitably deemed as a practical approach to a marketing problem; “How to engage low category users through the social media – the case of the make-up sector in Portugal”. Design/methodology/approach: Online structured questionnaires and in-depth interviews were used. The questionnaire was answered by 110 women aged from 15 to 45 years old and the interviews were conducted with 14 women of the same age. The interviews provided key insights for the questionnaire formulation. Findings: Women are poorly informed on make-up properties and characteristics, feeling a genuine concern in regard to this subject. Lack of time, occasional usage and skin damage are the main barriers for make-up usage by low category users. Overcoming these aspects pass by demystifying the association of make-up with skin damage and emphasise the functional and emotional benefits of make-up. Further, brands need to create contents more consumer-oriented and ask directly to fans/followers suggestions and other insights. Resort to Portuguese “common” women for greater empathy in campaigns, promote online meetings between followers and make-up professionals on social media; and finally take advantage of the hybrid condition of Facebook, which incorporates multiple forms of content presentation, including videos, the most appealing format of make-up presentation for women. Research limitations/implications: Further studies addressing this topic, by using larger samples and study of specific make-up brands and campaign programs, over social media to reach a solid growth potential of make-up market evidences in Portugal. Originality/ value: Make-up brands are emphasising their interest in linking social media and marketing their promotional mix around social marketing.

The importance of the ligation of the inferior thyroid artery in parathyroid function after subtotal thyroidectomy

We prospectively studied the effects of the ligation of the inferior thyroid artery (ITA) on postoperative hypoparathyroidism in 48 patients who underwent functional subtotal thyroidectomy. Patients were randomized into two groups: A, with bilateral ligation of the ITA and B, without ligation of the ITA. Parathyroid function was checked preoperatively and after surgery by clinical examination and measurement of total calcium, intact PTH, urinary calcium, and AMPc. RESULTS: A significant incidence of postoperative hypocalcemia occurred: 17% in group A and 13% in B on the 4th postoperative day. Six months later, the incidence was 5% in Group A and 0% in Group B. These differences were not statistically significant between the two groups, and neither were any of the other clinical and laboratory observations. CONCLUSION: The ligation of the ITA was not an important causal factor for the occurrence of postoperative hypocalcemia after subtotal thyroidectomy.

Vaccines in pregnancy: a review of their importance in Brazil

Neonates and young children remain susceptible to many serious infectious diseases preventable through vaccination. In general, current vaccines strategies to prevent infectious diseases are unable to induce protective levels of antibodies in the first 6 months of life. Women vaccinated during pregnancy are capable of producing immunoglobulin antibodies that are transported actively to the fetus, and maternal immunization can benefit both the mother and the child. With few exceptions, maternal immunization is not a routine, because of the concerns related to the safety of this intervention. Ethical and cultural issues make the studies on maternal immunization difficult; however, in the last decade, the development of new vaccines, which are very immunogenic and safe has reactivated the discussions on maternal immunization. In this paper we present a review of the literature about maternal immunization based on MEDLINE data (1990 to 2002). The most important conclusions are: 1) there is no evidence of risk to the fetus by immunizing pregnant women with toxoids, polysaccharide, polysaccharide conjugated and inactive viral vaccines; 2) most viral attenuated vaccines are probably safe too, but data is still insufficient to demonstrate their safety; therefore these vaccines should be avoided in pregnant women; 3) in Brazil, there is a need for a maternal immunization program against tetanus. Many new candidate vaccines for maternal immunization are available, but studies should be conducted to evaluate their safety and efficacy, as well as regional priorities based on epidemiological data.

Design and implementation of an assurance map at Sonae retail business

The present Working Project aims at studying the topic of assurance mapping in a specific organizational context of a Portuguese retail company. For this purpose, an assurance map framework was designed to support the decision making process of stakeholders, through the delivery of comfort concerning risks, operations and control. In the end, the framework was successfully implemented for the process sourcing of goods in two business units of the company. Although, further implementation of the framework proved not to be feasible during the project’s timespan, it is expected to occur in the near future.

Habitat preferences, diet, feeding strategy and social organization of the black spider monkey [Ateles paniscus paniscus Linnaeus 1758] in Surinam

A Socioecological Field Study.This monograph reports on a 26 month socioecological study of black spider monkeys (Ateles paniscus paniscus)in the Raleigh-vallen — Voltzberg Nature Reserve, Surinam. It recognizes the fundamental importance of food to the behavior and the regulation of population density fox this primate. It clarifies the complex temporal and spatial effects of tropical rain forest food sources on the behavior of a group of spider monkeys, concentrating on food category, food plant identity and phenology, and quantity, density and dispersion of the most important food sources. In addition, the present study describes habitat choice, optimal feeding strategy and sexual behavior of the spider monkey, and discusses implications of diet for social behavior. This study is also fundamental to conservation. Specialized in eating mature fruits, the spider monkey is a very important dispersal agent for many trees and lianes, particularly canopy species. However, the spider monkey is probably the most vulnerable monkey species in Surinam and it is disappearing rapidly throughout the remainder of its range. Unfortunately, it is large and noisy and can be easily tracked and hunted. It is largely restricted to undisturbed high forest, and consequently habitat destruction has more effect on it than on most other species. Together with its slow reproductive rate (a female gives birth only once every four or five years), this means that the species is poorly adapted to recover from exploitation. In order to implement proper measures for conservation, data on forest type preferences, diet and social behavior of the species, or on closely related species, in undisturbed areas, such as the one described in this monograph, are essential tools for assessing the potential of proposed protected areas.

Improving retail banking staff incentive systems

This Work Project seeks to analyze the viability, utility and best way of implementing mechanisms of double accounting and of insertion of low (or null) sales objectives in an incentives program. The main findings are that both processes are possible and to a certain extent advisable, although in very specific ways and with some limitations. Double accounting processes are especially effective between different segments and networks and should have a greater impact in the first evaluation periods of each case and the null objectives, albeit usable, are recommended to be always substituted by positive objectives, even if quite small. Moreover, it is concluded that the formal structure of the incentives program influences significantly these concepts, namely concerning the duration of the evaluation periods and the interaction of the objectives of different entities for both the vertical (hierarchic) and horizontal (individual and collective) levels.

The global shopper & brands communication at airports

This project aims to illuminate two perspectives on travel retail. On the one hand, it describes the main character of the shopping scenario at airports, namely the Global Shopper. It covers the entire profile of the referred character, the main nationalities that represent him and the current shopping trends of the passenger. Also estimates of the booming nationalities and the future purchasing trends are accurately presented. On the other hand, the travel retail market is analyzed from the airport brands’ perspective. It is described what is currently done in terms of brands communication in the top ten airports around the world and the expected future market retail trends. To accurately explore the Global Shopper behavior and purchasing preferences, a market research was conducted with a sample of 128 respondents, male and female, from different nationalities, age groups, occupation and education backgrounds. The essay tests hypothesis regarding the relevance of several variables in the purchasing process of the Global Shopper in order to understand the most pleasant way to approach consumers in travel retail. The main variables studied concern the reasons to shop at airports, to whom the passenger shops, the preferred category and brand of purchase, feelings while shopping abroad, impulsive buying behavior, brand loyalty, the use of mobile devices in the shopping process, brands communication at airports, pre-ordering online and the attitude towards self-service stores. Some findings were in accordance with expectations, while others were a surprise and may produce valuable recommendations for future travel retail practices. 4 The main relevant results concern two areas, namely pre-ordering online and self-service stores. Results showed a certain stress about not having enough time to choose between the various offerings in travel retail, as well as difficulty in dealing with crowed stores. However, pre-ordering online was not common, which would be an initiative that could solve the discomfort at airport’s stores. Moreover, self-service would promote efficiency in stores allowing passengers to save time if they already know how to go through the shopping process by themselves. Another possible recommendation concerns differentiating the strategy in travel retail for the two genders. Some differences were found in the categories bought by male and female, as well as to how brands should shape their approach concerning the demands of each gender.

Omni-channel retail strategies in the luxury world

It’s impossible to neglect the changes that internet and e-commerce caused in the retail sector, by increasing customers’ expectations and forcing retailers to adapt the business to the new digital era. Internet is characterized by the increase in accessibility to everyone, which can be good or not so. For instance, luxury products rely on the sense of exclusivity, instead of being accessible to everyone. Hence, internet represents a challenge for luxury brands once, although they are able to provide a fullness service to their customers, they need to maintain the exclusiveness in which luxury is sustained. Consequently, the appearance of omni-channel was more than a challenge for the luxury sector, in particular, given the need to provide a full integrated experience through different channels. The aim of this dissertation is to find out how important is omni-channel, even in the luxury industry, and how it’s actually implemented based on the case of one of the most successful companies on luxury fashion e-commerce industry – Farfetch. Even though the company started in London, its founder is a Portuguese entrepreneur, and it’s in Portugal where most of its employees work, divided in two offices – Guimarães e Porto. Therefore, a literature review was written on relevant concepts and ideas about luxury, e-commerce and the different channels’ approaches. There were formulated five propositions that were after discussed according to the information gathered about the company and its strategies. In the end, it was possible to identify which propositions are in accordance with theory and which are not, as well as understand which are the most important strategies and trends about omni-channel in the luxury fashion e-commerce sector.

A doença pulmonar obstrutiva crónica e o exercício: impacto da doença no declínio funcional e importância do treino de exercício nos benefícios para a saúde

RESUMO: A reabilitação respiratória (RR) é uma intervenção abrangente e interdisciplinar dirigida aos doentes respiratórios crónicos e inclui o treino de exercício, programas de educação e de modificação comportamental, entre outros, desenhados individualmente para melhorar o desempenho físico e psicossocial e promover a adesão a longo prazo a comportamentos promotores de saúde. A doença pulmonar obstrutiva crónica (DPOC) é uma doença comum, afetando cerca de 210 milhões de pessoas em todo o mundo, com elevada mortalidade e com custos económicos significativos decorrentes do agravamento progressivo da doença, das hospitalizações e de reinternamentos frequentes. Apesar do crescente conhecimento da DPOC e do papel da RR nos benefícios para a saúde, existem aspetos ainda não esclarecidos que têm impacto na prática clínica e de investigação e nas decisões das autoridades de saúde. A primeira parte desta tese focou a DPOC e o seu impacto negativo e incluiu: o estudo da prevalência da DPOC em Portugal; os fatores clínicos e funcionais que se associam à mortalidade em doentes com DPOC avançada; a morbilidade, impacto funcional e risco dos doentes se tornarem dependentes para as atividades diárias e a influência da inflamação sistémica. A prevalência estimada da DPOC de 14,2% indica que esta é uma doença comum em Portugal e alerta para a necessidade de uma maior sensibilização da população, dos profissionais de saúde e autoridades de saúde com vista a um diagnóstico precoce e à alocação dos recursos terapêuticos adequados. A elevada taxa de mortalidade em doentes com DPOC avançada - 36,6% em 3 anos - associou-se a insuficiência respiratória, a elevado número de exacerbações, ao cancro do pulmão e a reduzida capacidade funcional para a marcha, salientando a importância da referenciação precoce para RR, a identificação e o tratamento das comorbilidades e a prevenção das exacerbações. A aplicação de um questionário que avaliou as atividades da vida diária básicas e instrumentais, permitiu identificar um marcador clínico do risco de dependência, complementando as avaliações funcionais e associando-se a outros marcadores de mau prognóstico, como as exacerbações. Em doentes com DPOC, com FEV1 médio de 46,76% (desvio padrão: 20,90%), 67% da categoria D do GOLD, verificou-se uma associação positiva entre a expressão de genes inflamatórios avaliada pela reação em cadeia da polimerase (ARN mensageiro de IFNg, IL1b, IL6, IL8, TNFa, TGFb1, iNOS) e o índice de massa corporal em repouso, acentuando-se após o exercício. Este estudo aponta a inflamação como o potencial elo de ligação entre a obesidade e a inflamação sistémica em doentes com DPOC. A segunda parte da tese focou a RR, nomeadamente os seus efeitos em doentes das categorias GOLD A, B, C e D; o impacto das comorbilidades nos resultados da RR e os resultados de diferentes intensidades de treino aeróbio. Após o programa de RR, verificaram-se melhorias significativas na capacidade de exercício funcional e de endurance e no estado geral de saúde dos doentes de todas as categorias GOLD. Esta classificação não distingue os doentes que melhor poderão beneficiar desta intervenção, indicando que devem ser referenciados para RR, os doentes sintomáticos ou com repercussão na qualidade de vida, independentemente da categoria da DPOC a que pertençam. A prevalência das comorbilidades no grupo de doentes com DPOC que é referenciado para RR, é elevada, sendo as mais frequentes, as cardiovasculares, as respiratórias e as psicológicas. Apesar de poderem diminuir o impacto da RR, os resultados desta foram semelhantes independentemente do número de comorbilidades. A identificação e o tratamento sistemáticos das comorbilidades conferem maior segurança clínica a esta intervenção terapêutica a qual, por apresentar bons resultados, não deve limitar a referenciação dos doentes. Com o programa de RR, verificou-se melhoria significativa em todos os resultados centrados no doente para ambas as intensidades de treino aeróbio, a 60% e a 80% da potência aeróbica máxima (Wmax), com melhoria do estado geral de saúde, nos sintomas e na capacidade para o exercício, o que questiona a indicação sistemática de elevadas intensidades de treino em doentes com DPOC para a obtenção de benefícios a curto prazo. Na terceira e última parte da tese foi estudado o papel da atividade física na DPOC, focando os fatores que influenciam a atividade física diária; a evolução da capacidade funcional e o estado de saúde 2 anos após um programa de RR e o papel da telemonitorização na quantificação e monitorização da atividade física. Confirmámos que os doentes com DPOC são marcadamente sedentários e os fatores que se associaram ao sedentarismo nestes doentes foram a dispneia e a distância percorrida na prova de marcha de seis minutos. Este estudo sublinha a importância do controlo sintomático, nomeadamente da dispneia, bem como, mais uma vez, o potencial papel da reabilitação respiratória no aumento da capacidade funcional para o exercício e na aquisição de hábitos de vida fisicamente ativa. Verificámos que, apesar de os doentes com DPOC apresentarem benefícios clinicamente significativos na capacidade funcional para o exercício e no estado geral de saúde com o programa de RR, apenas os que se mantêm ativos, podem, no final dos dois anos de seguimento, manter os efeitos benéficos desse programa. O sistema de telemonitorização que combina a oximetria e a quantificação da atividade física provou ser clinicamente útil na avaliação da necessidade de oxigenoterapia de longa duração (OLD) e na aferição do débito de oxigénio em repouso, no esforço e no sono, podendo contribuir para uma melhor adequação da prescrição da OLD. A monitorização dos níveis de atividade física regular é um importante instrumento de avaliação dos programas de RR e o seu uso potencial na telereabilitação permitirá prolongar a eficácia dos programas e reduzir os custos associados aos cuidados de saúde.---------------------------------------------------------------------------------------------------ABSTRACT: Pulmonary rehabilitation (PR) is a comprehensive interdisciplinary intervention that includes, but is not limited to, exercise training, education, and behavior change, individually designed to improve physical and psychological conditions of people with chronic respiratory disease and to promote long-term adherence to health-enhancing behaviors. Chronic obstructive pulmonary disease (COPD) is a common disease, affecting about 210 million people worldwide, with high mortality and significant health-related costs due to disease progression, hospitalizations and frequent hospital readmissions. Although the increasing knowledge about COPD and benefitial outcomes of PR, some aspects with impact in clinical practice, research and health authorities’ decisions, remain to be clarified. The first part of this thesis focused on COPD and its negative impact, including the study of COPD prevalence in Portugal; clinical and functional factors associated with mortality in advanced COPD patients; morbidity, functional impact and risk of others’ dependance to perform activities of daily living; and the role of systemic inflammation. The evidence of 14.2% estimated COPD prevalence as a common disease in Portugal raises the need of an increasing awareness of population, health care professionals and health authorities towards an earlier diagnosis and apropriate treatment resources allocation. High mortality in patients with advanced COPD – 36.6% in 3 years - was associated with respiratory failure, high frequency of exacerbations, lung cancer and a low functional capacity in walking. This highlightens the importance of an earlier referral to PR, comorbidity identification and treatment, and prevention of exacerbations. A questionnaire evaluated basic and instrumental activities of daily living, and identified a clinical marker of the risk of becoming dependent. This clinical marker complemented other functional evaluations and was associated with prognosis markers such as the number of exacerbations. In COPD patients with a mean FEV1 46.76% (SD 20.90%), 67% belonging to GOLD grade D, we found a positive association between inflammatory gene expression evaluated by polymerase chain reaction (IFNg, IL1b, IL6, IL8, TNFa, TGFb1, iNOS RNA messenger) and body mass index at rest, and a further increase with exercise. This study evidenced obesity as one potential link between COPD and systemic inflammation. The second part of this thesis focused PR, namely its outcomes in patients of GOLD categories A, B, C and D; comorbidities impact in PR outcomes, and the impact of different exercise training intensities in patient related outcomes. xviii With PR intervention, we found significant improvement in functional exercise capacity, endurance exercise capacity and health status in patients of all GOLD categories. This classification did not differentiate which patients would benefit more from PR, hence all symptomatic patients with a negative impact in health status should be referred to PR, regardless of the GOLD category they belong to. There is a high prevalence of comorbidities in COPD patients referred to PR, being cardiovascular, respiratory and psychological, the most prevalent. Although some comorbidities might reduce PR impact, the results were similar regardless of the number of comorbidities. Systematic comorbidities identification and treatment provides safety to PR intervention, and its good results should not preclude patients referral. With PR intervention we found a significant improvement in all patient reported outcomes for exercise training intensities at 60% and 80% maximum work rate (Wmax), namely in health status, symptoms and exercise capacity. These findings challenge the current systematic indication of high exercise training intensities to achieve PR short-term benefits. In the third and last part of the thesis, the role of physical activity in COPD was studied, focusing factors that may influence daily physical activity; the evolution of functional capacity and health status two years after a PR program, and the role of a telemonitoring system in physical activity quantification and monitoring. We confirmed that COPD patients are markedly inactive and factors associated with a sedentary lifestyle are dyspnea and 6 minute walking distance. This study emphasized the importance of symptom control, namely of dyspnea, as well as, once again, the potential role of PR in functional exercise improvement and in integrating physically active habits in daily life. We verified that, although COPD patients improve functional exercise capacity and health status after a PR program, only those who kept physical activity habits were able to maintain those effects after 2 years of follow-up. A telemonitoring system that combines oximetry and physical activity quantification proved to be clinically useful in the evaluation of long-term oxygen therapy (LTOT) indication, as well as in the titration of oxygen levels at rest, exertion, and sleeping, which might contribute to a more adequate LTOT prescription. Monitoring of daily physical activity levels is an important PR evaluation instrument and its potential use in telerehabilitation might allow lengthening programs efficacy, while reducing health-care costs.

Emotional aspects of childhood career development: importance and future agenda

Childhood is a central period for career and social-emotional development. However, the literature covering childhood career development and the role of emotions in careers is scarce. In this article, we advocate for the consideration of emotions in childhood career development. Emotional aspects of children’s career exploration, key-figures and interests, as well as of childhood antecedents of lifelong career processes are presented. Relations between childhood emotion, behavior, functioning and learning are also presented. Conclusions center on a call for focused study of the role of emotion in childhood career development and how such an agenda will advance the literature.
