Neural correlates of sexual cue reactivity in individuals with and without compulsive sexual behaviours

Although compulsive sexual behaviour (CSB) has been conceptualized as a "behavioural" addiction and common or overlapping neural circuits may govern the processing of natural and drug rewards, little is known regarding the responses to sexually explicit materials in individuals with and without CSB. Here, the processing of cues of varying sexual content was assessed in individuals with and without CSB, focusing on neural regions identified in prior studies of drug-cue reactivity. 19 CSB subjects and 19 healthy volunteers were assessed using functional MRI comparing sexually explicit videos with non-sexual exciting videos. Ratings of sexual desire and liking were obtained. Relative to healthy volunteers, CSB subjects had greater desire but similar liking scores in response to the sexually explicit videos. Exposure to sexually explicit cues in CSB compared to non-CSB subjects was associated with activation of the dorsal anterior cingulate, ventral striatum and amygdala. Functional connectivity of the dorsal anterior cingulate-ventral striatum-amygdala network was associated with subjective sexual desire (but not liking) to a greater degree in CSB relative to non-CSB subjects. The dissociation between desire or wanting and liking is consistent with theories of incentive motivation underlying CSB as in drug addictions. Neural differences in the processing of sexual-cue reactivity were identified in CSB subjects in regions previously implicated in drug-cue reactivity studies. The greater engagement of corticostriatal limbic circuitry in CSB following exposure to sexual cues suggests neural mechanisms underlying CSB and potential biological targets for interventions

The effect of antipsychotic medication on sexual function and serum prolactin levels in community-treated schizophrenic patients: results from the Schizophrenia Trial of Aripiprazole (STAR) study (NCT00237913)

<p>Abstract</p> <p>Background</p> <p>The aim of this paper is to evaluate the effect of antipsychotics for the treatment of schizophrenia in a community based study on sexual function and prolactin levels comparing the use of aripiprazole and standard of care (SOC), which was a limited choice of three widely used and available antipsychotics (olanzapine, quetiapine or risperidone) (The Schizophrenia Trial of Aripiprazole [STAR] study [NCT00237913]).</p> <p>Method</p> <p>This open-label, 26-week, multi-centre, randomised study compared aripiprazole to SOC (olanzapine, quetiapine or risperidone) in patients with schizophrenia (DSM-IV-TR criteria). The primary effectiveness variable was the mean total score of the Investigator Assessment Questionnaire (IAQ) at Week 26. The outcome research variables included the Arizona Sexual Experience scale (ASEX). This along with the data collected on serum prolactin levels at week 4, 8, 12, 18 and 26 will be the focus of this paper.</p> <p>Results</p> <p>A total of 555 patients were randomised to receive aripiprazole (n = 284) or SOC (n = 271). Both treatment groups experienced improvements in sexual function from baseline ASEX assessments. However at 8 weeks the aripiprazole treatment group reported significantly greater improvement compared with the SOC group (p = 0.007; OC). Although baseline mean serum prolactin levels were similar in the two treatment groups (43.4 mg/dL in the aripiprazole group and 42.3 mg/dL in the SOC group, p = NS) at Week 26 OC, mean decreases in serum prolactin were 34.2 mg/dL in the aripiprazole group, compared with 13.3 mg/dL in the SOC group (p < 0.001).</p> <p>Conclusion</p> <p>The study findings suggest that aripiprazole has the potential to reduce sexual dysfunction, which in turn might improve patient compliance.</p

Respir Res

Background: Sexual function is often affected in patients suffering from chronic diseases especially chronic obstructive pulmonary disease (COPD). However, the effect of COPD on sexual satisfaction is underappreciated in clinical practice. The aim of this study is to evaluate the impact of COPD on patient’s sexuality and the explanatory variables of sexual dissatisfaction. Methods: Questionnaires were emailed to participants and they submitted their responses on the Santé Respiratoire France website. Data about sexual well-being (Arizona Sexual Experience Scale, ASEX), Quality of life (VQ11), anxiety, depression (Hospitalized anxiety and depression, HAD) and self-declared COPD grade were collected. Results: Seven hundred and fifty one subjects were included and were characterized as follows: women—51%, mean age—61 years, in a couple—62% and 70%—retired. Every grade of COPD was represented. Out of 751 participants, 301 participants (40%) had no sexual activity and 450 (60%) had sexual activity. From the 450 participants, 60% needed to change their sexual life because of their disease (rhythm, frequency and position). Subjects often used medications to improve sexual performance (43% used short-acting bronchodilator and 13% -specific erectile dysfunction drugs). ASEX questionnaire confirmed patients’ dissatisfaction (diminution of sexual appetite for 68% and sexual desire for 60%) because of breathlessness and fatigue. Eighty one percent of the responders had an altered quality of life (VQ11 mean score 35) and frequent suspected anxiety or depression (HAD mean score 10.8). Ninety percent declared that sexual dysfunction had never been discussed by their doctors, while 36% of patients would have preferred to undergo a specialized consultation. Conclusion: Sexual dysfunction is frequent among COPD patients and leads to an altered well-being, however being a cultural taboo, it remains frequently neglected. Sexual guidance should be a part of patient’s consultations improve quality of sexual life. © 2020, The Author(s)

Routine Outcomes Monitoring to Support Improving Care for Schizophrenia: Report from the VA Mental Health QUERI

In schizophrenia, treatments that improve outcomes have not been reliably disseminated. A major barrier to improving care has been a lack of routinely collected outcomes data that identify patients who are failing to improve or not receiving effective treatments. To support high quality care, the VA Mental Health QUERI used literature review, expert interviews, and a national panel process to increase consensus regarding outcomes monitoring instruments and strategies that support quality improvement. There was very good consensus in the domains of psychotic symptoms, side-effects, drugs and alcohol, depression, caregivers, vocational functioning, and community tenure. There are validated instruments and assessment strategies that are feasible for quality improvement in routine practice
