All-cause and Cardiovascular mortality among ethnic German immigrants from the Former Soviet Union: a cohort study

BACKGROUND: Migration is a phenomenon of particular Public Health importance. Since 1990, almost 2 million ethnic Germans (Aussiedler) have migrated from the former Soviet Union (FSU) to Germany. This study compares their overall and cardiovascular disease (CVD) mortality to that of Germany's general population. Because of high overall and CVD mortality in the FSU and low socio-economic status of Aussiedler in Germany, we hypothesize that their mortality is higher. METHODS: We conducted a retrospective cohort study for 1990–2002 with data of 34,393 Aussiedler. We assessed vital status at population registries and causes of death at the state statistical office. We calculated standardized mortality ratios (SMRs) for the whole cohort and substrata of covariables such as age, sex and family size. To assess multivariate effects, we used Poisson regression. RESULTS: 1657 cohort members died before December 31, 2002, and 680 deaths (41.03%) were due to CVD. The SMR for the whole cohort was 0.85 (95%-CI 0.81–0.89) for all causes of death and 0.79 (95%-CI 0.73–0.85) for CVD. SMRs were higher than one for younger Aussiedler and lower for older ones. There was no clear effect of duration of stay on SMRs. For 1990–93, SMRs were significantly lower than in subsequent years. In families comprising at least five members upon arrival in Germany, SMRs were significantly lower than in smaller families. CONCLUSION: In contrast to our hypothesis on migrants' health, overall and CVD mortality among Aussiedler is lower than in Germany's general population. Possible explanations are a substantially better health status of Aussiedler in the FSU as compared to the local average, a higher perceived socio-economic status of Aussiedler in Germany, or selection effects. SMR differences between substrata need further exploration, and risk factor data are needed

Experiences of medical and pharmacy students’ learning in a shared environment: A qualitative study

Background. Patient care is significantly affected by doctors and pharmacists, who have specialised knowledge and skills. In establishing an interprofessional undergraduate learning environment, medical and pharmacy students have the opportunity to start working in a collaborative manner early on in their careers.Objectives. To implement combined clinical visits, where medical and pharmacy students jointly encounter patients, and to establish the students’ perceptions of working in an interprofessional team.Methods. Final-year pharmacy students together with third-year medical students at the University of the Witwatersrand, Johannesburg, South Africa were invited to participate in weekly joint patient  encounters at a central academic hospital from May to July 2012. Students assessed patient records and participated in the patient consultation, guided by the supervising doctor. Participants from each  discipline were invited to attend a disciplinespecific focus group discussion, where they shared their  perceptions and experiences. The discussions were audio-taped and transcribed verbatim. Content  analysis was used to analyse the transcriptions. Ethics approval was obtained from the Human Research Ethics Committee of the University.Results. Four themes were identified: the meeting of professions; shared teaching and learning;  reciprocity in teaching and learning; and valuing the experience. It is evident that there was a change in students’ attitudes, and they developed mutual respect and a better understanding of their professional role and that of their peers. They also reported positive experiences in learning from and with one another.Conclusion. This study focused on eliciting students’ perceptions and attitudes towards interprofessional teaching and learning. The positive responses to the experiences suggest that further learning  opportunities should be created with students from another discipline

A review of the major biological approaches to control the worldwide pest Tetranychus urticae (Acari: Tetranychidae) with special reference to natural pesticides

The two-spotted spider mite, Tetranychus urticae Koch, is a phytophagous pest that can cause significant yield losses in many agricultural crops, including fruits, cotton, vegetables, and ornamentals. To date, 3877 host species have been reported around the world in both outdoor crops and greenhouses. In this paper, we present the common methods to control this pest including chemical and biological practices. While synthetic acaricides have been widely used to manage T. urticae, in recent years, interest in pesticides derived from plants has increased considerably as a result of environmental concerns and pest population resistance to conventional pesticides. Some botanical pesticides can be easily produced,are relatively efficient against pests, and with few exceptions, their mammalian toxicity and persistence in the environment is low. Thus, the use of plant extracts appears to be a promising alternative strategy for pest management. The present paper reviews studies on the biocidal activities of plant extracts, including essential oils, against T. urticae, a plant-feeding mite found worldwide and a serious agricultural and home garden pest
