Selected AbstractsTowards a fuller understanding of mosquito behaviour: use of electrocuting grids to compare the odour-orientated responses of Anopheles arabiensis and An. quadriannulatus in the fieldMEDICAL AND VETERINARY ENTOMOLOGY, Issue 2 2008S. J. TORR Abstract The epidemiological role of and control options for any mosquito species depend on its degree of ,anthropophily'. However, the behavioural basis of this term is poorly understood. Accordingly, studies in Zimbabwe quantified the effects of natural odours from cattle and humans, and synthetic components of these odours, on the attraction, entry and landing responses of Anopheles arabiensis Giles (Diptera: Culicidae) and Anopheles quadriannulatus Theobald. The numbers of mosquitoes attracted to human or cattle odour were compared using electrocuting nets (E-nets), and entry responses were gauged by the catch from an odour-baited entry trap (OBET) relative to that from an odour-baited E-net. Landing responses were estimated by comparing the catches from E-nets and cloth targets covered with an electrocuting grid. For An. arabiensis, E-nets baited with odour from a single ox or a single man caught similar numbers, and increasing the dose of human odour from one to three men increased the catch four-fold. For An. quadriannulatus, catches from E-nets increased up to six-fold in the progression: man, three men, ox, and man + ox, with catch being correlated with bait mass. Entry responses of An. arabiensis were stronger with human odour (entry response 62%) than with ox odour (6%) or a mixture of cattle and human odours (15%). For An. quadriannulatus, the entry response was low (< 2%) with both cattle and human odour. Anopheles arabiensis did not exhibit a strong entry response to carbon dioxide (CO2) (0.2,2 L/min). The trends observed using OBETs and E-nets also applied to mosquitoes approaching and entering a hut. Catches from an electrocuting target baited with either CO2 or a blend of acetone, 1-octen-3-ol, 4-methylphenol and 3-n-propylphenol , components of natural ox odour , showed that virtually all mosquitoes arriving there alighted on it. The propensity of An. arabiensis to enter human habitation seemed to be mediated by odours other than CO2 alone. Characterizing ,anthropophily' by comparing the numbers of mosquitoes caught by traps baited with different host odours can lead to spurious conclusions; OBETs baited with human odour caught around two to four times more An. arabiensis than cattle-baited OBETs, whereas a human-baited E-net caught less (, 0.7) An. arabiensis than a cattle-baited E-net. Similar caution is warranted for other species of mosquito vectors. A fuller understanding of how to exploit mosquito behaviour for control and surveys requires wider approaches and more use of appropriate tools. [source] Safer sex decision-making among men with haemophilia and HIV and their female partnersHAEMOPHILIA, Issue 1 2001K. L. Parish An exploratory qualitative study of adult heterosexual men with haemophilia and HIV and women who were their sexual partners was conducted as formative research to better understand cognitive factors involved in behavioural intentions and practices which comprise HIV risk-reduction for sexual transmission. The study sought to generate hypotheses, uncover themes, and develop a broad perspective on possible determinants of behaviours related to HIV transmission risk reduction. Qualitative analysis of these data served as a basis for developing a subsequent quantitative, hypothesis-testing survey and an intervention. Face-to-face interviews were conducted with 23 single men and 28 married men with haemophilia and HIV infection, and 28 married women partners selected through stratified, purposeful sampling. The interviews identified beliefs, attitudes, and values underlying decisions regarding target behaviours related to preventing sexual transmission of HIV, including (1) using condoms consistently during vaginal intercourse and (2) talking to partners about risk reduction. The interviews elicited information about perceived advantages and disadvantages of performing each of the targeted behaviours, and factors that facilitate or prevent performing them. Qualitative analysis of coded responses yielded important themes regarding how choices are made about sexual activity and safer sex. Most notably, communication between partners (1) plays a direct, key role in facilitating condom use and (2) forms the basis for maintaining emotional intimacy in these relationships. The link between condom use and communicating about safer sex was viewed as pivotal in achieving HIV prevention for individuals in serodiscordant couples. Recommendations for risk reduction intervention development are discussed. [source] Caring for mom and neglecting yourself?HEALTH ECONOMICS, Issue 9 2009The health effects of caring for an elderly parent Abstract We examine the physical and mental health effects of providing care to an elderly mother on the adult child caregiver. We address the endogeneity of the selection in and out of caregiving using an instrumental variable approach, using the death of the care recipient and sibling characteristics. We also carefully control for baseline health and work status of the adult child. We explore flexible specifications, such as Arellano,Bond estimation techniques. Continued caregiving over time increases depressive symptoms and decreases self-rated health for married women and married men. In addition, the increase in depressive symptoms is persistent for married women. While depressive symptoms for single men and women are not affected by continued caregiving, there is evidence of increased incidence of heart conditions for single men, and that these effects are persistent. Robustness checks indicate that these health changes can be directly attributable to caregiving behavior, and not due to a direct effect of the death of the mother. The initial onset of caregiving has modest immediate negative effects on depressive symptoms for married women and no immediate effects on physical health. Negative physical health effects emerge 2 years later, however, suggesting that there are delayed effects on health that would be missed with a short recall period. Initial caregiving does not affect health of married men. Published in 2009 by John Wiley & Sons, Ltd. [source] Use of Commercial Sex Workers Among Hispanic Migrants In North Carolina: Implications for the Spread of HIVPERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 4 2004Emilio A. Parrado CONTEXT: Rates of HIV and AIDS have risen among U.S. Hispanics and in migrant-sending regions of Mexico and Central America, pointing to a link between migration and HIV. However, little is known about male migrants' sexual risk behaviors, such as the use of commercial sex workers. METHODS: The prevalence and frequency of commercial sex worker use was examined among 442 randomly selected Hispanic migrants in Durham, North Carolina. Logistic and Poisson regression techniques were used to model predictors of commercial sex worker use, and descriptive data on condom use with commercial sex workers were examined. RESULTS: Twenty-eight percent of respondents reported using the services of a commercial sex worker during the previous year; rates reached 46% among single men and 40% among married men living apart from their wives. Men with spouses in Durham were less likely than other men to use commercial sex workers (odds ratio, 0.1). Among men who used commercial sex workers, the frequency of visits declined with greater education (incidence rate ratio, 0.9) and increased with hourly wage (1.1). Frequency and use declined with years of residence, although the results were of borderline significance. Reported rates of condom use with commercial sex workers were high, but were likely to fall if familiarity with a commercial sex worker increased. CONCLUSIONS: Commercial sex workers represent an important potential source of HIV infection. Educational and behavioral interventions that take into account social context and target the most vulnerable migrants are needed to help migrants and their partners avoid HIV infection. [source] Systematic review of post-treatment psychosocial and behaviour change interventions for men with cancerPSYCHO-ONCOLOGY, Issue 3 2010Hannah L. Dale Abstract Objectives: The psychosocial impacts of a cancer diagnosis include reduced quality of life, poorer inter-personal relationships, hopelessness and mental illness. Worse outcomes, including mortality rates have been found for single men with cancer compared with women and partnered men. The aim of this systematic review was to examine the effectiveness of post-treatment psychosocial and behaviour change interventions for adult men with cancer, in order to inform the development of an intervention. A focus on single men was intended. Methods: Ten databases were searched via Ovid and Web of Science. Papers were systematically extracted by title, abstract and full paper according to the inclusion/exclusion criteria. Full papers were assessed by two authors. Inclusion criteria: participants at any stage of a cancer diagnosis, ,50% male and aged 18+; psychosocial and/or behavioural post-treatment interventions, using any format; a one,three level of evidence. Couple/carer/family interventions were excluded. Results: From 9948 studies initially identified, 11 were finally included in the review. They implemented cognitive behaviour therapy, hypnosis or psychoeducational interventions. All studies had some positive results, however, lack of reporting of intervention content and methodological issues limit the findings. No studies intervened with single men, and none provided comparative outcomes for marital status. Conclusions: Effectiveness of interventions was difficult to assess as, while all had benefits, their generalisability was limited due to methodological and reporting limitations. Improved reporting procedures are required to allow for replication. Copyright © 2009 John Wiley & Sons, Ltd. [source] | ||||||||||
