Conceptualizing Sexual Wellbeing: A Qualitative Investigation to Inform Development of a Measure (Natsal-SW).

Despite increasing scientific and policy interest in sexual wellbeing, it remains poorly conceptualized. Many studies purporting to measure it instead measure related but distinct concepts, such as sexual satisfaction. This lack of conceptual clarity impedes understanding, measuring, and improving sexual wellbeing. We present qualitative research from multi-stage, mixed-methods work to develop a new measure of sexual wellbeing (Natsal-SW) for the fourth British National Survey of Sexual Attitudes & Lifestyles. Literature review and discussion generated a conceptual framework with seven proposed domains: respect, self-esteem, comfort, self-determination, safety and security, forgiveness, and resilience. Semi-structured interviews with 40 adults aged 18-64 then explored whether and how these domains aligned with participants' own understandings, experiences, and language of sexual wellbeing. Data were analyzed thematically. Participants conceptualized sexual wellbeing as distinct from sexual satisfaction and sexual health and as multidimensional, dynamic, and socially and structurally influenced. All seven proposed domains resonated with accounts of sexual wellbeing as a general construct. The personal salience of different domains and their dimensions varied between individuals (especially by gender and sexual orientation) and fluctuated individually over time. This study clarifies dimensions of domains that participants considered important, providing an empirical basis to inform development of a new measure of sexual wellbeing.

Salivary Testosterone and Sexual Function and Behavior in Men and Women: Findings from the Third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3).

Using data from the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3) we examined associations between salivary testosterone (Sal-T) and sexual function and behavior. Single morning saliva samples were self-collected from a subsample of participants aged 18-74 years and analyzed using mass spectrometry. 1,599 men and 2,123 women were included in the analysis (40.6% of those invited to provide a sample). We adjusted for confounders in a stepwise manner: in model 1 we adjusted for age only; model 2 for age, season and relationship status, and model 3 we added BMI and self-reported health. In the fully adjusted models, among men, Sal-T was positively associated with both partnered sex (vaginal sex and concurrent partners) and masturbation. Among women, Sal-T was positively associated with masturbation, the only association with partnered sex was with ever experience of same-sex sex. We found no clear association between Sal-T and sexual function. Our study contributes toward addressing the sparsity of data outside the laboratory on the differences between men and women in the relationship between T and sexual function and behavior. To our knowledge, this is the first population study, among men and women, using a mass spectrometry Sal-T assay to do so.

Does the number of doses matter? A qualitative study of HPV vaccination acceptability nested in a dose reduction trial in Tanzania.

BACKGROUND: The multi-dose regimen is a known barrier to successful human papillomavirus (HPV) vaccination. Emerging evidence suggests that one vaccine dose could protect against HPV. While there are clear advantages to a single dose schedule, beliefs about vaccine dosage in low and middle income countries (LMICs) are poorly understood. We investigated acceptability of dose-reduction among girls, and parents/guardians of girls, randomised to receive one, two or three doses in an HPV vaccine dose-reduction and immunobridging study (DoRIS trial) in Tanzania. METHODS: Semi-structured interviews with girls (n = 19), and parents/guardians of girls (n = 18), enrolled in the study and completing their vaccine course. RESULTS: Most participants said they entrusted decisions about the number of HPV vaccine doses to experts. Random allocation to the different dose groups did not feature highly in the decision to participate in the trial. Given a hypothetical choice, girls generally said they would prefer fewer doses in order to avoid the pain of injections. Parental views were mixed, with most wanting whichever dose was most efficacious. Nonetheless, a few parents equated a higher number of doses with greater protection. CONCLUSION: Vaccine trials and programmes will need to employ careful messaging to explain that one dose offers sufficient protection against HPV should emerging evidence from ongoing dose-reduction clinical trials support this.

Anterior Insular Cortex is Critical for the Propensity to Relapse Following Punishment-Imposed Abstinence of Alcohol Seeking.

Humans with alcohol use disorder typically abstain because of the negative consequences associated with excessive drinking, and exposure to contexts previously associated with alcohol use can trigger relapse. We used a rat model that captures a characteristic of this human condition: namely voluntary abstinence from alcohol use because of contingent punishment. There is substantial variability in the propensity to relapse following extended periods of abstinence, and this is a critical feature preventing the successful treatment of alcohol use disorder. Here we examined relapse following acute or prolonged abstinence. In male alcohol preferring P rats, we found an increased propensity to relapse in Context B, the punishment context after prolonged abstinence. Next, we found that neither alcohol intake history nor the motivational strength of alcohol predicted the propensity to relapse. We next examined the putative circuitry of context-induced relapse to alcohol seeking following prolonged abstinence using Fos as a marker of neuronal activation. The anterior insular cortex (AI) was the only brain region examined where Fos expression correlated with alcohol seeking behavior in Context B after prolonged abstinence. Finally, we used local infusion of GABAA and GABAB receptor agonists (muscimol + baclofen) to show a causal role of the AI in context-induced relapse in Context B, the punishment context after prolonged abstinence. Our results show that there is substantial individual variability in the propensity to relapse in the punishment-associated context after prolonged abstinence, and this is mediated by activity in the AI.SIGNIFICANCE STATEMENT A key feature of alcohol use disorder is that sufferers show an enduring propensity to relapse throughout their lifetime. Relapse typically occurs despite the knowledge of adverse consequences including health complications or relationship breakdowns. Here we use a recently developed rodent model that recapitulates this behavior. After an extended period of abstinence, relapse propensity is markedly increased in the "adverse consequence" environment, akin to humans with alcohol use disorder relapsing in the face of adversity. From a circuitry perspective, we demonstrate a causal role of the anterior insular cortex in relapse to alcohol seeking after extended abstinence following punishment imposed voluntary cessation of alcohol use.

Painful sex (dyspareunia) in women: prevalence and associated factors in a British population probability survey.

OBJECTIVE: To estimate the prevalence of painful sex among women in Britain, and to explore associated sexual, relationship and health factors that should be considered in assessment. DESIGN: Multi-stage, clustered and stratified population probability sample survey, using computer-assisted self-interview. Sample frame was the British Postcode Address File. SETTING: Participants interviewed at home between 2010 and 2012. SAMPLE: A total of 15 162 adults aged 16-74 years (8869 women). Data reported from 6669 sexually active women. METHODS: Age-adjusted logistic regressions to examine associations between painful sex and indicators of sexual, relational, mental and physical health. MAIN OUTCOME MEASURE: Physical pain as a result of sex for ≥3 months in the past year, plus measures of symptom severity. RESULTS: Painful sex was reported by 7.5% (95% CI 6.7-8.3) of sexually active women, of whom one-quarter experienced symptoms very often or always, for ≥6 months, and causing distress. Reporting painful sex was strongly associated with other sexual function problems, notably vaginal dryness (age adjusted odds ratio 7.9; 6.17-10.12), anxiety about sex (6.34; 4.76-8.46) and lacking enjoyment in sex (6.12; 4.81-7.79). It was associated with sexual relationship factors [such as not sharing same level of interest in sex (2.56; 1.97-3.33)], as well as with adverse experiences such as non-volitional sex (2.17; 1.68-2.80). Associations were also found with measures of psychological and physical health, including depressive symptoms (1.68; 1.28-2.21). CONCLUSION: Painful sex is reported by a sizeable minority of women in Britain. Health professionals should be supported to undertake holistic assessment and treatment which takes account of the sexual, relationship and health context of symptoms. TWEETABLE ABSTRACT: Painful sex-reported by 7.5% of women in Britain-is linked to poorer sexual, physical, relational and mental health.

How can we objectively categorise partnership type? A novel classification of population survey data to inform epidemiological research and clinical practice.

BACKGROUND: Partnership type is a determinant of STI risk; yet, it is poorly and inconsistently recorded in clinical practice and research. We identify a novel, empirical-based categorisation of partnership type, and examine whether reporting STI diagnoses varies by the resulting typologies. METHODS: Analyses of probability survey data collected from 15 162 people aged 16-74 who participated in Britain's third National Survey of Sexual Attitudes and Lifestyles were undertaken during 2010-2012. Computer-assisted self-interviews asked about participants' ≤3 most recent partners (N=14 322 partners/past year). Analysis of variance and regression tested for differences in partnership duration and perceived likelihood of sex again across 21 'partnership progression types' (PPTs) derived from relationship status at first and most recent sex. Multivariable regression examined the association between reporting STI diagnoses and partnership type(s) net of age and reported partner numbers (all past year). RESULTS: The 21 PPTs were grouped into four summary types: 'cohabiting', 'now steady', 'casual' and 'ex-steady' according to the average duration and likelihood of sex again. 11 combinations of these summary types accounted for 94.5% of all men; 13 combinations accounted for 96.9% of all women. Reporting STI diagnoses varied by partnership-type combination, including after adjusting for age and partner numbers, for example, adjusted OR: 6.03 (95% CI 2.01 to 18.1) for men with two 'casual' and one 'now steady' partners versus men with one 'cohabiting' partner. CONCLUSIONS: This typology provides an objective method for measuring partnership type and demonstrates its importance in understanding STI risk, net of partner numbers. Epidemiological research and clinical practice should use these methods and results to maximise individual and public health benefit.

Salivary Testosterone Levels and Health Status in Men and Women in the British General Population: Findings from the Third National Survey of Sexual Attitudes and Lifestyles (Natsal-3).

CONTEXT: Salivary T (Sal-T) measurement by liquid chromatography-tandem mass spectroscopy resents the opportunity to examine health correlates of Sal-T in a large-scale population survey. OBJECTIVE: This study sought to examine associations between Sal-T and health-related factors in men and women age 18-74 years. DESIGN AND SETTING: Morning saliva samples were obtained from participants in a cross-sectional probability-sample survey of the general British population (Natsal-3). Self-reported health and lifestyle questions were administered as part of a wider sexual health interview. PARTICIPANTS: Study participants included 1599 men and 2123 women. METHODS: Sal-T was measured using liquid chromatography-tandem mass spectroscopy. Linear regression was used to examine associations between health factors and mean Sal-T. RESULTS: In men, mean Sal-T was associated with a range of health factors after age adjustment, and showed a strong independent negative association with body mass index (BMI) in multivariable analysis. Men reporting cardiovascular disease or currently taking medication for depression had lower age-adjusted Sal-T, although there was no association with cardiovascular disease after adjustment for BMI. The decline in Sal-T with increasing age remained after adjustment for health-related factors. In women, Sal-T declined with increasing age; however, there were no age-independent associations with health-related factors or specific heath conditions with the exception of higher Sal-T in smokers. CONCLUSIONS: Sal-T levels were associated, independently of age, with a range of self-reported health markers, particularly BMI, in men but not women. The findings support the view that there is an age-related decline in Sal-T in men and women, which cannot be explained by an increase in ill health. Our results demonstrate the potential of Sal-T as a convenient measure of tissue androgen exposure for population research.

Comparison of Ha-ras mutational spectra of N-methyldibenzo[c,g]carbazole and 7H-dibenzo[c,g]carbazole-induced mouse skin tumors.

Carcinogenic N-heterocyclic aromatic hydrocarbons are formed during the incomplete combustion of fossil fuels as well as cigarette smoke. N-Methyldibenzo[c,g]carbazole (NMeDBC) and 7H-dibenzo[c,g]carbazole (DBC) are members of this group. DBC induces mouse skin and liver tumors, whereas NMeDBC induces only mouse skin tumors. The objective of this study was to elucidate the mechanism of action of these compounds in skin by assessing the Ha-ras mutational spectra induced by a two-stage initiation-promotion protocol. NMeDBC (200 nmol) or DBC (200 nmol) was applied to the back skin of 24 female Hsd:ICR(Br) mice (12 per group) once. 12-O-tetradecanoylphorbol-13-acetate (TPA) (2 microg) was then applied twice weekly for 28 wk. Tumors were screened for Ha-ras mutations using enriched polymerase chain reaction and mutations defined by dideoxy sequencing. In DBC animals 58% produced papillomas, of which 71% had codon 61 mutations, 4% had codon 12 mutations, 4% had codon 13 mutations, and 21% had no Ha-ras mutations. In NMeDBC animals 92% produced papillomas, of which 73% had codon 61 mutations and 27% had no Ha-ras mutations. All of the codon 61 mutations, from both NMeDBC and DBC, were CAA-->CTA transversions. The DBC-induced tumors with the codon 12 mutation had a GGA-->GAA transition, and the codon 13 mutation was a GGC-->GTC transversion. These results suggest that NMeDBC is a more potent tumor inducer than DBC, but the resulting H-ras mutations in each group were predominantly in codon 61, and, therefore, mutation induction in skin by each chemical appears to proceed by a similar mechanism.

Frequent Ha-ras mutations in murine skin and liver tumors induced by 7H-dibenzo[c,g]carbazole.

7H-dibenzo[c,g]carbazole (DBC) is a potent liver and skin carcinogen when topically applied to the back skin of mice. This compound is found in complex mixtures produced during incomplete combustion of fossil fuels as well as in wood and tobacco smoke. The objective of this study was to elucidate the mechanism of action of this compound by assessing the Ha-ras mutational spectra of skin and liver tumors induced in a mouse model system. Low doses (50 nmol) and high doses (100 nmol) of DBC were applied topically to the backs of Hsd:ICR(Br) mice twice weekly. No treatment and solvent application were used as controls. After the mice were killed, the skin and liver tumors were removed, DNA was isolated, and tumor DNA was screened for Ha-ras codon 12, 13, and 61 mutations by using an enriched polymerase chain reaction method. Mutations were confirmed by reverse cyclic dideoxy sequencing. No mutations were found in codons 12 and 13 of DBC-induced tumors, whereas one acetone-control tumor had a codon 13 mutation. Sixty-seven percent of skin tumors and 45% of liver tumors induced by high doses of DBC and 67% of skin tumors induced by low doses of DBC contained codon 61 mutations, whereas liver tumors induced by low doses of DBC did not. The codon 61 mutations were exclusively A:T-->T:A transversions within the second base (CAA-->CTA). These results indicate that DBC is a unique polycyclic aromatic hydrocarbon in that it induces both skin and liver tumors upon topical application and that the mutational spectra are the same in tumors from two target organs, skin and liver, yet different from tumors from a third target organ, lung.

The legislation of active voluntary euthanasia in Australia: will the slippery slope prove fatal?

At 2.00 am on the morning of May 24, 1995 the Northern Territory Legislative Assembly Australia passed the Rights of the Terminally Ill Act by the narrow margin of 15 votes to 10. The act permits a terminally ill patient of sound mind and over the age of 18 years, and who is either in pain or suffering, or distress, to request a medical practitioner to assist the patient to terminate his or her life. Thus, Australia can lay claim to being the first country in the world to legalise voluntary active euthanasia. The Northern Territory's act has prompted Australia-wide community reaction, particularly in South Australia, Tasmania and the Australian Capital Territory where proposals to legalise euthanasia have already been defeated on the floor of parliament. In New South Wales (NSW) the AIDS Council of NSW has prepared draft euthanasia legislation to be introduced into the Upper House as a Private Member's Bill some time in 1996. In this paper, we focus on a brief description of events as they occurred and on the arguments for and against the legalisation of euthanasia which have appeared in the media.

'These sorts of people don't do very well': race and allocation of health care resources.

Recent literature has highlighted issues of racial discrimination in medicine. In order to explore the sometimes subtle influence of racial determinants in decisions about resource allocation, we present the case of a 53-year-old Australian Aboriginal woman with end-stage renal failure. The epidemiology of renal failure in the Australian Aboriginal population and amongst other indigenous peoples is discussed. We show that the use of utilitarian outcome criteria for resource allocation may embody subtle racial discrimination where consideration is not given to issues of justice, race, culture and gender. It is only where the processes by which resources are allocated are transparent, clearly defined and based upon consultation with individual patients that issues and justice are likely to be adequately addressed.

Teaching clinical ethics as a professional skill: bridging the gap between knowledge about ethics and its use in clinical practice.

Ethical reasoning and decision-making may be thought of as 'professional skills', and in this sense are as relevant to efficient clinical practice as the biomedical and clinical sciences are to the diagnosis of a patient's problem. Despite this, however, undergraduate medical programmes in ethics tend to focus on the teaching of bioethical theories, concepts and/or prominent ethical issues such as IVF and euthanasia, rather than the use of such ethics knowledge (theories, principles, concepts, rules) to clinical practice. Not surprisingly, many students and clinicians experience considerable difficulty in using what they know about ethics to help them make competent ethical decisions in their day-to-day clinical practice. This paper describes the development of a seminar programme for teaching senior medical students a more systematic approach to ethical reasoning and analysis and clinical decision-making.

Ethical reasoning and decision-making in the clinical setting: assessing the process.

Clinical ethical reasoning and analysis are skills as central to good patient care as the efficient application of biomedical knowledge to diagnosis and prognosis. However, experience in teaching clinical ethics to senior medical students has indicated that simply trying to 'apply' the knowledge learnt about ethical theories, principles, concepts and rules in the clinical setting does not ensure ethical competence in clinical decision-making. In 1992, we developed and piloted a three-session programme that focused on a more systematic approach to the way students identified and attempted to manage ethical issues in their clinical practice. This programme was modified and improved in 1993 and further expanded in 1994. Our experience suggests that many students are now better able to bridge what has been called the 'gap' between the possession of ethical knowledge and its actual use in clinical decision-making. The remaining problem was assessment. How do you assess clinical ethical reasoning and decision-making? In the preclinical years of medical education, knowledge-based assessment tools, like the modified essay question (MEQ), provide a means for assessing the sensitivity of students to ethical issues. However, such tools permit neither an appraisal of how students actually make clinical ethical decisions, nor which factors students perceive as important in making an actual clinical decision. In order to make this type of appraisal, we developed a format for a written case report that facilitated our assessing the process as well as the end-product, the decision.(ABSTRACT TRUNCATED AT 250 WORDS)

Guidelines for no-CPR orders.

A no-CPR decision is not synonymous with abandonment and does not, of itself, rescind the obligations of the health care team to provide the highest quality care. Rather, a no-CPR order is best seen as one element of a comprehensive and dynamic management plan which should be reviewed and changed as the patient's medical condition warrants. A no-CPR order, therefore, offers an opportunity to rethink the goals of therapy in the light of discussions with the critically ill patient and his or her family.

Assessing the clinical ethical competence of undergraduate medical students.

At the University of Newcastle, health law and ethics is taught and assessed in each year of the five-year curriculum. However, the critical question for assessment remains: 'Does teaching ethics have a measurable effect on the clinical activity of medical students who have had such courses?' Those responsible for teaching confront this question each year they sit down to construct their assessment tools. Should they assess what the student knows? Should they assess the student's moral reasoning, that is, what decisions the student makes, and, how these decisions are justified, or should they assess what the student actually does when dealing with patients in the clinical setting, and how he or she does it? From 1982 to 1991, assessment at Newcastle was primarily aimed at determining the quality of the students' ethics knowledge base. This paper describes the strengths and limitations of a purely knowledge-based method of evaluation and why in 1992, we are now attempting to redefine and assess, what we call 'clinical ethical competence' in terms of how students actually apply this knowledge base in a controlled clinical context.

Medical futility, treatment withdrawal and the persistent vegetative state.

Why do we persist in the relentless pursuit of artificial nourishment and other treatments to maintain a permanently unconscious existence? In facing the future, if not the present world-wide reality of a huge number of persistent vegetative state (PVS) patients, will they be treated because of our ethical commitment to their humanity, or because of an ethical paralysis in the face of biotechnical progress? The PVS patient is cut off from the normal patterns of human connection and communication, with a life unlike other forms of human existence. Why the struggle to justify ending a life which, it is said, has suffered an irreversible loss of the content of consciousness? Elsewhere, the authors have addressed the ethical controversies and confusion engendered by ambiguous terminology, misuse of medical facts and the differing interpretations of what constitutes 'effective' treatment: in particular, the issue of whether in fact artificial nutrition and hydration is a medical treatment, or simply part of the obligatory care owed to all patients, permanently unconscious or not. In this paper, we intend to argue that recent analyses of medical futility, its meaning and ethical implications, despite an absence of public consensus, permit some tentative re-evaluation of our ethical obligations to the PVS patient.
