Sexual Relationships in Hispanic Countries: a Literature Review

This is a pre-print of an article published in Current Sexual Health Reports. The final authenticated version is available online at: https://doi.org/10.1007/s11930-020-00272-6Purpose of Review: Sexuality is a complex dimension for which culture seems to play an important role, particularly in countries that are more traditional. This review summarizes the knowledge about sexual relationships in Hispanic countries, considering sexual debut, attitudes, behaviors, and satisfaction. Recent Findings: In line with the literature reviewed, the sexual double standard seems to be continuing to influence sexual relationships. Some countries show more open expressions of sexuality based on the level of gender inequality or sexualized context, and within countries, variables such as religious commitment, family characteristics, and access to resources may play important roles in sexuality. Summary: Future research, policies, and interventions should consider these specific characteristics, including these forms of expression of sexuality, in the adjustment of cross-cultural and cross-national strategies

Brief Engagement and Acceptance Coaching for Community and Hospice Settings (the BEACHeS Study): Protocol for the development and pilot testing of an evidence-based psychological intervention to enhance wellbeing and aid transition into palliative care

Background: Cancer affects millions of individuals globally, with a mortality rate of over eight million people annually. Although palliative care is often provided outside of specialist services, many people require, at some point in their illness journey, support from specialist palliative care services, for example, those provided in hospice settings. This transition can be a time of uncertainty and fear and there is a need for effective interventions to meet the psychological and supportive care needs of people with cancer that cannot be cured. While Acceptance and Commitment Therapy (ACT) has been shown to be effective across diverse health problems, robust evidence for its effectiveness in palliative cancer populations is not extensive. Method: This mixed-methods study uses a single-case experimental design with embedded qualitative interviews to pilot test a novel intervention for this patient group. Between 14 and 20 patients will be recruited from two hospices in England and Scotland. Participants will receive five face-to-face manualised sessions with a psychological therapist. Sessions are structured around teaching core ACT skills (Openness, Awareness and Engagement) as a way to deal effectively with challenges of transition into specialist palliative care services. Outcome measures include: cancer-specific quality of life (primary outcome) and distress (secondary outcome), which are assessed alongside measures of psychological flexibility. Daily diary outcome assessments will be taken for key measures, alongside more detailed weekly self-report, through baseline, intervention and one-month follow-up phases. After follow-up, participants will be invited to take part in a qualitative interview to understand their experience of taking part, and acceptability and perceived effectiveness of the intervention and its components. Discussion: This study is the first investigation of using ACT with terminally ill patients at the beginning of their transition into palliative treatment. Using in-depth single-case approaches, we will refine and manualise intervention content by the close of the study for use in follow-up research trials. Our long-term goal is then to test the intervention as delivered by non-psychologist specialist palliative care practitioners thus broadening the potential relevance of the approach

An appraisal of the value of the contaminated Poisson method to estimate the dose inhomogeneity in simulated partial-body exposure.

The situation in which inhomogeneous radiation exposure is likely to occur with accidental overexposure was simulated by studying chromosome aberrations in mixtures of male irradiated and female nonirradiated lymphocytes. The data were evaluated by means of the contaminated Poisson method. For X-ray doses from 1 to 10 Gy and ratios of irradiated to nonirradiated blood from 1:1 to 1:19, a good agreement was found between calculated and applied radiation doses and fractions exposed

Selection and hydroponic growth of potato cultivars for bioregenerative life support systems

As part of the ESA-funded MELiSSA program, Ghent University and the Université catholique de Louvain investigated the suitability, growth and development of four potato cultivars in hydroponic culture under controlled conditions with the aim to incorporate such cultivation system in an Environmental Control and Life Support System (ECLSS). Potato plants can fulfill three major functions in an ECLSS in space missions: (a) fixation of CO2 and production of O2, (b) production of tubers for human nutrition and (c) production of clean water after condensation of the water vapor released from the plants by transpiration. Four cultivars (Annabelle, Bintje, Desiree and Innovator) were selected and grown hydroponically in nutrient film technique (NFT) gullies in a growth chamber under controlled conditions. The plant growth parameters, tuber harvest parameters and results of tuber nutritional analysis of the four cultivars were compared. The four potato cultivars grew well and all produced tubers. The growth period lasted 127 days for all cultivars except for Desiree which needed 145 days. Annabelle (1.45 kg/m2) and Bintje (1.355 kg/m2) were the best performing of the four cultivars. They also produced two times more tubers than Desiree and Innovator. Innovator produced the biggest tubers (20.95 g/tuber) and Desiree the smallest (7.67 g/tuber). The size of Annabelle and Bintje potatoes were intermediate. Bintje plants produced the highest total biomass in term of DW. The highest non-edible biomass was produced by Desiree, which showed both the highest shoot and root DW. The manual length and width measurements were also used to predict the total tuber mass. The energy values of the tubers remained in the range of the 2010 USDA and Souci-Fachmann-Kraut food composition databases. The amount of Ca determined was slightly reduced compared to the USDA value, but close to the Souci-Fachmann-Kraut value. The concentration of Cu, Zn and P were high compared to both databases. Clearly, the yields for the four cultivars used in this study can still be significantly increased. Identification of optimal growth conditions (a.o. nutrient solution management, light conditions) will be the subject of further research
