The effect of Schistosoma mansoni infection on child morbidity in the State in Bahia, Brazil: II — Analysis at the individual level

The present investigation was carried out on a sample of 840 children (5 to 16 years old) from ten small towns of the State of Bahia in northeastern Brazil. The objetive was to study, by using a cross sectional methodology, the evolution of schistosomiasis morbidity (hepatic and splenic enlargement) in children, and the role of the intensity of S. mansoni infection in this process. The children were analised in three age groups (5 to 8, to 12 and 13 to 16 years old) and classified as uninfected, mildly infected, moderately infected and heavily infected according to the number of eggs in the stool. In children aged 5 to 8 years, increasing egg counts were not associated with increasing frequencies of hepatic or splenic enlargement. In the 9 to 12 years old group and association was observed with the prevalence of hepatic enlargement, but not with the prevalence of spleen enlargement. In the oldest group, 13 to 16 years old, an association was observed with the prevalence of enlargement of both organs. It was evident that in this population schistosomiasis morbidity develops in the early period of life as a gradual process starting with liver enlargement and followed by spleen enlargement some years later. It was found that the intensity of infection has a fundamental role in this process, although there is a latent period of some years before clinical splenomegaly appears in moderate-heavily infected children. The Authors suggest that the prevalence of splenomegaly in the 13 to 16 years old group is a good measure of the community level of schistosomiasis morbidity and could be used to measure the impact of control programs.

Concomitant rotavirus serotypes 1 and 4 infections in a diarrhoeic child from Belém, Brazil

Concomitant serotypes 1 and 4 infections were detected in a 15-month old female child with community-acquired diarrhoea which lasted 7 days and coursed with moderate dehydration. The evidence for dual rotavirus infection was offered by the following findings: a) enzyme-linked immunosorbent assay (ELISA) positive reactions to both 1 and 4 serotypes; and b) extra-migrating bands at electro-phoresis of RNA in polyacrylamide gel (PAGE). These results suggest that children living under poor sanitation conditions are heavily exposed to rotavirus infections; in addition, the co-circulation of different serotypes in the same setting sustains the current concept that a rotavirus vaccine should be rnultivalent, in order to protect children against the four epidemiologically important rotavirus G serotypes.

Maximizing the Social Welfare of Virtual Power Players Operation in Case of Excessive Wind Power

The integration of growing amounts of distributed generation in power systems, namely at distribution networks level, has been fostered by energy policies in several countries around the world, including in Europe. This intensive integration of distributed, non-dispatchable, and natural sources based generation (including wind power) has caused several changes in the operation and planning of power systems and of electricity markets. Sometimes the available non-dispatchable generation is higher than the demand. This generation must be used; otherwise it is wasted if not stored or used to supply additional demand. New policies and market rules, as well as new players, are needed in order to competitively integrate all the resources. The methodology proposed in this paper aims at the maximization of the social welfare in a distribution network operated by a virtual power player that aggregates and manages the available energy resources. When facing a situation of excessive non-dispatchable generation, including wind power, real time pricing is applied in order to induce the increase of consumption so that wind curtailment is minimized. This method is especially useful when actual and day-ahead resources forecast differ significantly. The distribution network characteristics and concerns are addressed by including the network constraints in the optimization model. The proposed methodology has been implemented in GAMS optimization tool and its application is illustrated in this paper using a real 937-bus distribution network with 20.310 consumers and 548 distributed generators, some of them non-dispatchable and with must take contracts. The implemented scenario corresponds to a real day in Portuguese power system.

An Exercise Program Improves Health-Related Quality of Life of Workers

Low back problems are associated with decreased quality of life. Specific exercises can improve quality of life, resulting in better professional performance and functionality. The purpose of this study was to evaluate the effect of following a 21-month exercise program on the quality of life of warehouse workers. The population included 557 male warehouse workers from a food distribution company in Oporto, Portugal. Upon application of the selection criteria, 249 workers were deemed eligible, which were randomized into two groups (125 in the intervention group and 124 in the control group). Then, subjects were asked to volunteer for the study, the sample being formed by 229 workers (112 in the intervention group and 117 in the control group). All subjects completed the SF-36 questionnaire prior to beginning the program and on the 11th and 21st months following it. The exercises were executed in the company facilities once a day for 8 min. Data were analyzed using SPSS® 17.0 for Windows®. After 11 months of following the exercise program, there was an increase in all scores for the experimental group, with statistically significant differences in the dimensions physical functioning (0.019), bodily pain (0.010), general health (0.004), and rolephysical (0.037). The results obtained at the end of the study (21 months) showed significant improvements in the dimensions physical functioning (p = 0.002), rolephysical (p = 0.007), bodily pain (p = 0.001), social functioning (p = 0.015), role-emotional (p = 0.011), and mental health (p = 0.001). In the control group all dimensions showed a decrease in mean scores. It can be concluded that the implementation of a low back specific exercise program has changed positively the quality of life of warehouse workers.

Safety climate and its relationship with furniture companies’ safety performance and workers’ risk acceptance

This study aims to analyse the relationship between safety climate and the level of risk acceptance, as well as its relationship with workplace safety performance. The sample includes 14 companies and 403 workers. The safety climate assessment was performed by the application of a Safety Climate in Wood Industries questionnaire and safety performance was assessed with a checklist. Judgements about risk acceptance were measured through questionnaires together with four other variables: trust, risk perception, benefit perception and emotion. Safety climate was found to be correlated with workgroup safety performance, and it also plays an important role in workers’ risk acceptance levels. Risk acceptance tends to be lower when safety climate scores of workgroups are high, and subsequently, their safety performance is better. These findings seem to be relevant, as they provide Occupational, Safety and Health practitioners with a better understanding of workers’ risk acceptance levels and of the differences among workgroups.

Expectativas de responsabilidade filial e orientação da responsabilidade no cuidado aos idosos

RESUMO: Muitos desenvolvimentos demográficos e estruturais ocorreram nas relações intergeracionais, os quais provocaram um impacto nas ligações familiares, tais como o aumento da longevidade e as alterações da dinâmica estrutural e social da família, tendo sido colocado em causa a vitalidade das obrigações familiares e solidariedade familiar, nomeadamente entre pais e filhos adultos. Assim, com este estudo pretendeu-se verificar a presença de solidariedade entre pais e os seus filhos adultos, assim como as expectativas de responsabilidade filial dos pais e as suas opiniões e preferências no que se refere à orientação da responsabilidade para família/ serviços públicos no cuidado aos idosos. De forma a alcançar os objectivos, foi aplicado um questionário a 97 alunos, da Universidade Sénior da Póvoa de Santa Iria, com 55 ou mais anos e que tivessem pelo menos um filho adulto. Foi possível chegar à conclusão de que existe solidariedade entre pais e filhos adultos, assim como os pais consideram que existe uma responsabilidade mista (família/Estado) no cuidado aos idosos e que preferem os apoios formais em detrimento dos informais (familiares) – contrariando a orientação familística. Contudo, apesar disso continuam a apresentar expectativas elevadas em relação à responsabilidade que os filhos devem ter para com os pais, nomeadamente a nível da dimensão de apoio emocional, sendo a dimensão de apoio instrumental a excepção. Desta forma, é possível concluir que há uma tendência por parte da população inquirida em preferir a complementaridade de apoios formais e informais, com consequente especialização de tarefas: instrumental e emocional, respectivamente-----------ABSTRACT: Intergenerational relations have been affected by demographical and structural changes that had impact on family relationships. The increase in life expectancy and the changes in the families’ structural and social dynamics have put at risk the vitality of family obligations and solidarity, namely between parents and adult children. Therefore, this research aimed at studying the existence of solidarity between parents and adult children as well as the parents’ expectations towards their children’s responsibilities and their views and preferences on family and welfare state responsibility as far as elderly people are concerned. In order to achieve this, a questionnaire was devised and subsequently applied to 97 participants attending the Universidade Sénior in Póvoa de Santa Iria, aged 55 or older, with at least one adult child. The results indicate that there is solidarity between parents and adult children and that parents consider that both the family and the state should share the responsibility towards elderly people. Moreover, the study proves that formal support is preferred to the detriment of an informal one (family), which contradicts the familistic approach. However, parents evince high expectations as far as children responsibility towards them is concerned, specially in terms of emotional support. This does not apply, however, to the instrumental support domain. In conclusion, the study indicates that the participants tend to prefer the complementariness of formal and informal support with subsequent task specialisation: instrumental and emotional, respectively.
