Prosociality: Promoting Helpful Behaviors Not Just Helpful Intentions

When social institutions (e.g. Religion and the State) give reminders to help others, it can promote prosociality. Shariff’s (2016) meta-analysis of prosociality indicates that religiosity promotes self-reported helping, but finds no consistent effect in lab-based behavioral measures of prosociality. Furthermore, existing behavioral measures are often not ecologically-valid representations of prosociality, leaving the unique effect of religion on helping unclear. This study explores the role of religion on helping, which is known to promote helping between group members, and the state, which promotes helping across groups, in a relatively valid behavioral helping scenario. Participants are reminded to help those in need either by a religious agent, a secular agent, by no agent, or not reminded and then are offered the opportunity to help a peer in need by donating their time. Results indicate that although self-reported intentions to help those in need are high, and associated with known covariates (e.g. empathy, gratitude, religiosity, etc.); low amounts of behavioral helping are seen. Results are discussed in the context of dispositional predictors of prosocial behavior, prosocial intentions and behaviors, and modifications based on group membership

Health psychology’s role in sexual health care

This article provides an overview of the current and potential role of health psychology in sexual health care. Research, which applies various behaviour change techniques, is reviewed alongside one of the most extensively used theories, the Theory of Planned Behaviour (see Conner and Sparks 2009). This paper aims to link theory to practice giving the reader an indication of the range of work that health psychologists are involved in, and how this could be applied to sexual healthcare practice which supports positive behaviour change

The sorption fate of active pharmaceutical ingredients in soils receiving high wastewater inputs and implications for risk assessments

Chapter 1 has been published in the following paper. Lees, K., Fitzsimons, M., Snape, J., Tappin, A. and Comber, S., 2016. Pharmaceuticals in soils of lower income countries: physico-chemical fate and risks from wastewater irrigation. Environment International, 94:712-723. Chapter 3 has been published in the following paper. Lees, K., Fitzsimons, M., Snape, J., Tappin, A. and Comber, S., 2018. Does abiotic really mean abiotic? Assessing different soil sterilisation methods for use in OECD 106. Chemosphere, 209, 61-67.Population growth, increasing affluence, and greater access to medicines have led to an increase in active pharmaceutical ingredients (APIs) entering sewerage networks. Wastewater in lower and lower middle-income countries use that use wastewater for irrigation may use untreated or poorly treated wastewater resulting in the potential for greater concentrations of APIs to enter soils in this way. Wastewater re-used for irrigation is currently not included in environmental risk assessments for APIs in soils. The addition of wastewater to soils changes the organic content and can increase the pH of soils, which will have an impact on the fate of any ionisable APIs introduced during the irrigation process. As the input of APIs to soil from wastewater irrigation is not currently included in the risk assessments, this is an area that requires increased attention. A study was undertaken using a modified sorption-desorption batch equilibrium method (OECD 106) to simulate the addition of synthetic wastewater (SWW) to soils compared to a normal OECD 106 study. The APIs studied were ofloxacin, propranolol, naproxen and nevirapine, and represent a range of API physico-chemical properties. These experiments showed that the changes to soil properties (pH and dissolved organic carbon (DOC)) caused by irrigation with SWW can change the fate of APIs in soils. The ionisation state of the API at the altered pH was more important for the positively charged propranolol than it was for the negatively charged naproxen and neutral nevirapine. The Kd and Log Koc increased during the sorption experiment in some cases with SWW. This has implications on the current terrestrial risk assessment where the trigger value for a more detailed soil risk assessment in at Log Koc >4. If the experiment is only performed in 10 mM CaCl2 as is currently required this may lead to unknown risks of APIs in wastewater irrigated soils not being taken into account. Three soil sterilisation or microbial enzyme suppression methods were investigated to identify how successful they were and if there was any impact on the soil physical chemical structure. Gamma irradiation, autoclaving and the addition of 0.2 g L-1 sodium azide were studied. None of the methods successfully sterilised the soils and some changes in soils were identified post-treatment. Autoclaving destroyed the soil structure, turning it into a fine powder and significantly increasing DOC. Sodium azide changed the pH of the loam soil but not the sandy loam soil. Literature suggested that gamma irradiation was the most likely to sterilise the soils with the least amount of disturbance to its physico-chemical properties but increases in DOC were identified in the current study. The changes to soils after sterilisation varied depending on the individual soil properties, indicating that soils should be studied on a case-by-case basis. Irrigation with wastewater provides continuous inputs of chemicals into soils throughout the growing season so it is vital that more work is done to understand the ultimate fate of pollutants in soil as a result. Wastewater has the potential to change the fate of chemicals in soils meaning that current risk assessments may not thoroughly assess all risks involved.AstraZenec

Blogging to Develop Honors Students’ Writing

After an exciting class discussion, you might want students to write conventional papers directed at you and focused ultimately on a grade, or you might prefer that they bring their further insights to their classmates, continuing and enriching the ongoing class collaboration. Blogging is an excellent way to implement the second option, continuing an exchange of ideas and providing students with another tool to improve their writing skills. Student class blogging offers many benefits—for student and instructor alike—compared to assigning conventional papers directed only at the instructor. The collaborative writing and peer editing inherent in blogging offer challenges as well as benefits, so guidance in facilitating a meaningful exchange as well as navigating the nuts-and-bolts technicalities may be useful to honors faculty who are establishing a class blog. Ideas for class exercises, assignments, and evaluative expectations co-designed by an instructor and a team of honors students may also help bring out maximum creativity and collegiality in the honors blog

Better methods, better data: landscaping the priorities for improving methodologies in vector control

This article addresses the evolving challenges in evaluating insecticide-based tools for vector control. In response to the emergence of insecticide resistance in major malaria vectors, novel chemistries and products are coming to market, and there is a need to review the available testing methodologies. Commonly used methods for evaluating insecticides, such as the World Health Organization (WHO) cone bioassay, are inadequate for the diverse range of tools now available. Innovation to Impact (I2I) has studied the variability in laboratory methods, with the aim of identifying key factors that contribute to variation and providing recommendations to tighten up protocols. The I2I Methods Landscape is a living document which presents a review of existing methods for evaluating vector control tools, with the scope currently extending to insecticide-treated nets (ITNs) and indoor residual sprays (IRS). The review reveals a lack of validation for many commonly used vector control methods, highlighting the need for improved protocols to enhance reliability and robustness of the data that is generated to make decisions in product development, evaluation, and implementation. A critical aspect highlighted by this work is the need for tailored methods to measure endpoints relevant to the diverse modes of action of novel insecticides. I2I envisage that the Methods Landscape will serve as a decision-making tool for researchers and product manufacturers in selecting appropriate methods, and a means to prioritise research and development. We call for collective efforts in the pro-active development, validation, and consistent implementation of suitable methods in vector control to produce the data needed to make robust decisions

Cognitive fusion as a candidate psychological vulnerability factor for psychosis:An experimental study of acute ∆9-tetrahydrocannabinol (THC) intoxication

Heavy cannabis use is associated with an increased risk of psychosis. However, the psychological mechanisms involved, and interactions with established risk factors for cannabis-related psychosis, remain unclear. This study examined the role of cognitive fusion, a candidate vulnerability factor for psychosis, during acute THC intoxication, and the interaction with key risk factors–developmental trauma and schizotypy. Twenty general population cannabis-using participants were administered THC or placebo in a within-participants, double-blinded randomised study. Developmental trauma, schizotypy and cognitive fusion were all associated with psychotic experiences during intoxication. Cognitive fusion accounted for increased psychotic experiences in those with developmental trauma and high schizotypy. Cognitive fusion may be a key mechanism by which developmental trauma and schizotypy increase risk of psychosis from cannabis use. This initial study is limited by a small sample and correlational design; a larger scale mediation study is now needed to support a causal argument. The findings have implications for psychological treatments and identifying those at risk of cannabis-related psychosis. Psychological interventions that target cognitive fusion may be more effective than generic approaches. People prone to cognitive fusion, particularly those with a history of developmental trauma and high in schizotypy, may be at higher risk for cannabis-related psychosis.</p

The impact of a human papillomavirus (HPV) vaccination campaign on routine primary health service provision and health workers in Tanzania: a controlled before and after study.

BACKGROUND: The burden of cervical cancer and shortage of screening services in Tanzania confers an urgent need for human papillomavirus (HPV) vaccination. However, the sustainability and impact of another new vaccine campaign in an under-resourced health system requires consideration. We aimed to determine the impact of the government's school-based HPV vaccine campaign in Kilimanjaro region on the provision of routine primary health services and staff workload. METHODS: Data on daily numbers of consultations were collected from health facility register books in 63 dispensaries and health centres in North-West Tanzania for 20 weeks in 2014. Changes in outpatient, antenatal care (ANC), family planning (FP) and immunisation service activity levels before, during and after the two HPV vaccination campaigns in 2014 in 30 facilities within Kilimanjaro region ('intervention facilities') were compared with changes in activity levels in 33 facilities in Arusha region ('controls'). Qualitative interviews were conducted with health workers in Kilimanjaro region who delivered HPV vaccination and those who remained at the facility during in-school HPV vaccine delivery to explore perceptions of workload and capacity. RESULTS: Health facility activity levels were low and very variable in both regions. Controlling for district, facility type, catchment population, clinical staff per 1000 catchment population and the timing of other campaigns, no evidence of a decrease in consultations at the health facility during HPV vaccination week was found across outpatient, ANC, routine immunisation and FP services. However, compared to the average week before and after the campaign, health workers reported longer working hours and patient waiting times, feeling over-stretched and performing duties outside their normal roles whilst colleagues were absent from the facility conducting the HPV vaccine campaign. CONCLUSION: Qualitative interviews with health workers revealed that staff absence from the health facility is common for a number of reasons, including vaccination campaigns. Health workers perceived that the absence of their colleagues increased the workload at the health facility. The numbers of consultations for each service on 'normal days' were low and highly variable and there was no clear detrimental effect of the HPV vaccination campaign on routine health service activity

Microbicides development programme: engaging the community in the standard of care debate in a vaginal microbicide trial in Mwanza, Tanzania.

BACKGROUND: HIV prevention research in resource-limited countries is associated with a variety of ethical dilemmas. Key amongst these is the question of what constitutes an appropriate standard of health care (SoC) for participants in HIV prevention trials. This paper describes a community-focused approach to develop a locally-appropriate SoC in the context of a phase III vaginal microbicide trial in Mwanza City, northwest Tanzania. METHODS: A mobile community-based sexual and reproductive health service for women working as informal food vendors or in traditional and modern bars, restaurants, hotels and guesthouses has been established in 10 city wards. Wards were divided into geographical clusters and community representatives elected at cluster and ward level. A city-level Community Advisory Committee (CAC) with representatives from each ward has been established. Workshops and community meetings at ward and city-level have explored project-related concerns using tools adapted from participatory learning and action techniques e.g. chapati diagrams, pair-wise ranking. Secondary stakeholders representing local public-sector and non-governmental health and social care providers have formed a trial Stakeholders' Advisory Group (SAG), which includes two CAC representatives. RESULTS: Key recommendations from participatory community workshops, CAC and SAG meetings conducted in the first year of the trial relate to the quality and range of clinic services provided at study clinics as well as broader standard of care issues. Recommendations have included streamlining clinic services to reduce waiting times, expanding services to include the children and spouses of participants and providing care for common local conditions such as malaria. Participants, community representatives and stakeholders felt there was an ethical obligation to ensure effective access to antiretroviral drugs and to provide supportive community-based care for women identified as HIV positive during the trial. This obligation includes ensuring sustainable, post-trial access to these services. Post-trial access to an effective vaginal microbicide was also felt to be a moral imperative. CONCLUSION: Participatory methodologies enabled effective partnerships between researchers, participant representatives and community stakeholders to be developed and facilitated local dialogue and consensus on what constitutes a locally-appropriate standard of care in the context of a vaginal microbicide trial in this setting.

How does cannabidiol (CBD) influence the acute effects of delta-9-tetrahydrocannabinol (THC) in humans? A systematic review

The recent liberalisation of cannabis regulation has increased public and scientific debate about its potential benefits and risks. A key focus has been the extent to which cannabidiol (CBD) might influence the acute effects of delta-9-tetrahydrocannabinol (THC), but this has never been reviewed systematically. In this systematic review of how CBD influences the acute effects of THC we identified 16 studies involving 466 participants. Ten studies were judged at low risk of bias. The findings were mixed, although CBD was found to reduce the effects of THC in several studies. Some studies found that CBD reduced intense experiences of anxiety or psychosis-like effects of THC and blunted some of the impairments on emotion and reward processing. However, CBD did not consistently influence the effects of THC across all studies and outcomes. There was considerable heterogeneity in dose, route of administration and THC:CBD ratio across studies and no clear dose-response profile emerged. Although findings were mixed, this review suggests that CBD may interact with some acute effects of THC
