- Quality of Life Scale and symptomatology of schizophrenic patients: A systematic reviewPublication . Pinho, L.M.G. de; Pereira, A.M.S.; Chaves, C.M.C.B.; Batista, PatríciaBackground: The Quality of Life Scale (QLS) was developed to assess the quality of life of patients with schizophrenia, by Heinrichs, Hanlon and Carpenter, in 1984. Objectives: This systematic review analysed the scientific evidence produced from the QLS results and its relationship with the symptomatology of patients with schizophrenia. Methods: An electronic search was conducted on Pubmed/Medline and Scopus to identify relevant papers published within the last ten years (January 2007 to December 2016). The inclusion criteria were: studies whose samples included only outpatients with schizophrenia; studies whose aim was to compare the QLS results with the symptomatology of schizophrenia; studies written in English. The PRISMA criteria for reporting systematic reviews and meta-analyses were used. Results: Twelve studies were included in this systematic review. A total of 1645 patients with schizophrenia from four different countries were analysed. Ten articles used a cross-sectional study methodology and 2 articles involved a longitudinal study. Conclusions: Synthesis suggests that quality of life/functioning in patients with schizophrenia can be influenced by negative symptoms. Nevertheless, in relation to positive and depressive symptoms, the results are not congruent nor consistent. Therefore, this literature review indicated that more research is needed in order to obtain better evidence with regards to the influence of that symptomatology on the quality of life/functioning in patients with schizophrenia.
- Living conditions and helicobacter pylori in adultsPublication . Amaral, Odete; Fernandes, Isabel; Veiga, Nélio; Pereira, Carlos; Chaves, Cláudia; Nelas, Paula; Silva, DanielIntroduction. Infection by the bacterium Helicobacter pylori (H. pylori) is transmissible and is considered a public health issue which affects people of all ages. The objective of this study was to identify factors (lifestyles, dietary factors, and hygiene conditions) related to the prevalence of H. pylori infection. Methods. We carried out an observational cross-sectional study with a community sample of adults from the municipalities of Viseu and Sátão, Portugal. The final sample resulted in 166 adults. The data were collected through a self-Administered questionnaire with questions regarding sociodemographic aspects and lifestyles. H. pylori infection was identified using the 13C-urea breath test. Results. No association was found between the prevalence of H. pylori infection and the use of tobacco, alcohol, or coffee or dietary factors. The prevalence of H. pylori infection was higher in adults who reported higher consumption of fried food and lower consumption of vegetables and fruit. H. pylori infection was significant for the variables of lower frequency of handwashing before going to the bathroom (p=0.02) and well water consumption (p=0.05). Conclusion. A significant association was found for H. pylori infection with the lower frequency of handwashing before going to the bathroom and the consumption of well water.
