Sexuality in Ultra-High Risk for Psychosis and First-Episode Psychosis. A Systematic Review of Literature

Efficacy and safety of repetitive transcranial magnetic stimulation (rTMS) in anejaculation: A randomized controlled trial

BACKGROUND

Anejaculation represents significant psychological distress and sexual and reproductive challenges among male individuals and couples. Effective fertility management options are available to address the reproductive challenges associated with anejaculation. However, there is a lack of methods to reverse the condition itself.

OBJECTIVES

This study aims to assess the effectiveness and safety of repetitive transcranial magnetic stimulation (rTMS) in patients suffering from anejaculation.

METHODS

A total of 94 patients with anejaculation individuals were randomly assigned to receive high-frequency (HF) stimulation on the left dorsolateral prefrontal cortex (DLPFC), low-frequency (LF) stimulation on the right DLPFC, and sham stimulation for 4 weeks, with daily sessions of stimulation occurring on five consecutive weekdays each week.

RESULTS

After 4 weeks of rTMS treatment, the patients in both the HF and LF groups exhibited a similar reduction in their male sexual health questionnaire for ejaculatory dysfunction bother/satisfaction score, Hamilton Anxiety Scale score, Hamilton Depression Scale score, and Pittsburgh Sleep Quality Inventory score, which were statistically significant compared with sham treatment. Additionally, there were no significant differences observed in erectile function and cognitive function across the three groups. However, there were notable disparities in the cure rates between HF- and LF-group patients (16.1% vs. 54.8%, p = 0.001). Additionally, it is worth noting that only two HF group patients and one LF group patient experienced spontaneously resolving minor adverse effects during the treatment process. At the 8-week follow-up, among patients who initially responded to the treatment, only one from the HF group experienced a relapse.

DISCUSSION AND CONCLUSION

The findings of this study demonstrate that rTMS represents a secure and efficacious remedy for anejaculation patients.

Sexually transmitted infections, sexual life and risk behaviours of people living with schizophrenia: systematic review and meta-analysis

BACKGROUND

Sexually transmitted infections (STIs), along with sexual health and behaviour, have received little attention in schizophrenia patients.

AIMS

To systematically review and meta-analytically characterise the prevalence of STIs and sexual risk behaviours among schizophrenia patients.

METHOD

Web of Science, PubMed, BIOSIS, KCI-Korean Journal Database, MEDLINE, Russian Science Citation Index, SciELO and Cochrane Central Register were systematically searched from inception to 6 July 2023. Studies reporting on the prevalence or odds ratio of any STI or any outcome related to sexual risk behaviours among schizophrenia samples were included. PRISMA/MOOSE-compliant (CRD42023443602) random-effects meta-analyses were used for the selected outcomes. Q-statistics, I2 index, sensitivity analyses and meta-regressions were used. Study quality and publication bias were assessed.

RESULTS

Forty-eight studies (N = 2 459 456) reporting on STI prevalence (including 15 allowing for calculation of an odds ratio) and 33 studies (N = 4255) reporting on sexual risk behaviours were included. Schizophrenia samples showed a high prevalence of STIs and higher risks of HIV (odds ratio = 2.11; 95% CI 1.23-3.63), hepatitis C virus (HCV, odds ratio = 4.54; 95% CI 2.15-961) and hepatitis B virus (HBV; odds ratio = 2.42; 95% CI 1.95-3.01) infections than healthy controls. HIV prevalence was higher in Africa compared with other continents and in in-patient (rather than out-patient) settings. Finally, 37.7% (95% CI 31.5-44.4%) of patients were sexually active; 35.0% (95% CI 6.6-59.3%) reported consistent condom use, and 55.3% (95% CI 25.0-82.4%) maintained unprotected sexual relationships.

CONCLUSIONS

Schizophrenia patients have high prevalence of STIs, with several-fold increased risks of HIV, HBV and HCV infection compared with the general population. Sexual health must be considered as an integral component of care.

Validity of self-reported male sexual function scales in a young Chinese population: a comparative study with clinician-assisted evaluation

Psychometric scales, commonly used to gauge sexual function, can sometimes be influenced by response biases. In our research from June 2020 to April 2021, we examined the accuracy of self-reported sexual function scales. We invited patients from the Department of Infertility and Sexual Medicine at the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China), who have male sexual dysfunction, to participate by filling out a self-reported version of a specific questionnaire. In addition, they went through a clinician-assisted version of this questionnaire, encompassing tools such as the Premature Ejaculation Diagnostic Tool (PEDT), the 6-item International Index of Erectile Function (IIEF-6), the Erection Hardness Scale (EHS), and the Masturbation Erection Index (MEI). Using the clinician-assisted version as a reference, we categorized patients and applied various statistical methods, such as the Chi-square test, intraclass correlation coefficient (ICC), logistic regression, and the Bland-Altman plot, to gauge reliability. In our study with 322 participants, we found that while there were no notable discrepancies in error rates based on our categorization, certain scales showed significant differences in terms of overestimation and underestimation, with the exception of the PEDT. The positive diagnosis rate consistency between the self-reported and clinician-assisted versions was observed. High ICC values between the two versions across the scales were indicative of remarkable reliability. Our findings show that the self-reported versions of tools such as EHS, IIEF-6, MEI, and PEDT are credible and hold clinical reliability. However, employing a dual-diagnosis approach might be more prudent to circumvent potential misdiagnoses.

Attachment and resilience as mediators or moderators in the relationship between trauma and psychotic-like experiences

BACKGROUND

A large body of evidence has established a tight relation between traumatic experiences (TEs) and psychotic-like experiences (PLEs). Nevertheless, more comprehensive models involving multiple interactions of serial or parallel mediations and moderations still need to be elucidated. Among the many potential mediators or moderators, insecure attachment and resilience play a key role in the association of stress with PLEs. Hence, we aim to explore the complex pathways that lead from different types of TEs to PLEs, involving attachment and resilience modeled as mediators or moderators.

METHODS

One thousand ten high school students completed the International Trauma Exposure Measure (ITEM), the 11-item Resilience Scale for Adults (RSA-11), the 16-item Prodromal Questionnaire (iPQ-16), and the Relationship Questionnaire (RQ). A path analysis was conducted to assess mediation and moderation.

RESULTS

The final model showed that the impact of childhood TEs on PLEs was mediated by a pathway through anxious-insecure attachment styles (i.e., fearful and preoccupied, respectively, 8.75 % and 8.53 % of the total effect) and personal resilience resources. Conversely, the avoidant-insecure attachment was associated with lower interpersonal resilience (b = 0.14 [0.08, 0.20]), which in turn moderated the impact of recent TEs on PLEs (interaction term b = 0.34 [0.21, 0.47]).

CONCLUSIONS

Our model examines a complex model that includes factors buffering the effect of traumatic experiences on PLEs. Our results highlight the importance of insecure-anxious attachment to personal resilience resources and of insecure-avoidant attachment to interpersonal resilience as potential targets for clinical practice.

The Italian Society of Andrology and Sexual Medicine (SIAMS), along with ten other Italian Scientific Societies, guidelines on the diagnosis and management of erectile dysfunction

PURPOSE

Erectile dysfunction (ED) is one of the most prevalent male sexual dysfunctions. ED has been in the past mistakenly considered a purely psycho-sexological symptom by patients and doctors. However, an ever-growing body of evidence supporting the role of several organic factors in the pathophysiological mechanisms underlying ED has been recognized.

METHODS

The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving several other National Societies to provide an updated guideline on the diagnosis and management of ED. Derived recommendations were based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system.

RESULTS

Several evidence-based statements were released providing the necessary up-to-date guidance in the context of ED with organic and psychosexual comorbidities. Many of them were related to incorrect lifestyle habits suggesting how to associate pharmacotherapies and counseling, in a couple-centered approach. Having the oral therapy with phosphodiesterase type 5 inhibitors as the gold standard along with several other medical and surgical therapies, new therapeutic or controversial options were also discussed.

CONCLUSIONS

These are the first guidelines based on a multidisciplinary approach that involves the most important Societies related to the field of sexual medicine. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving couple sexual satisfaction and overall general health.

Sexual Dysfunctions and Problematic Sexuality in Personality Disorders and Pathological Personality Traits: A Systematic Review

PURPOSE OF REVIEW

This aim of the present systematic literature review is to critically analyze problematic sexuality and sexual dysfunctions in personality disorders (PDs) and pathological personality traits.

RECENT FINDINGS

An initial pool of 123 studies was found, out of which 17 met the selection criteria and were therefore included. Traumatic experiences as childhood sexual abuse and adverse childhood experiences characterize the relationship between sexual behavior and PDs. From this point of view, sexual compulsivity and sexual risk behaviors, typical of BPD and ASPD, respectively, are among the pathognomonic aspects of PDs and of pathological personality traits. A maladaptive personality functioning may manifest through a problematic sexuality and a sexual impairment. In this regard, traumatic life experiences may structure personality together with sexual functioning. Therefore, it would be useful to consider the relationship between trauma, sexuality, and personality in research and in the clinical setting.

Sexual and Reproductive Health in Adolescents and Young Adults With Psychotic Disorders: A Scoping Review

BACKGROUND AND HYPOTHESIS

The sexual and reproductive health (SRH) of young people with psychosis has been largely overlooked. We hypothesised that there are key deficiencies in the existing literature on the SRH of adolescents and young adults with psychotic disorders.

STUDY DESIGN

We conducted a systematic scoping review using Pubmed, Web of Science, Embase, PsycINFO, and CINAHL. We included empirical studies and case reports focused on SRH issues in young people (aged 14-24 years) with psychotic disorders. A qualitative synthesis was completed. Joanna Briggs Institute Critical Appraisal Tools were utilized to assess study quality.

STUDY RESULTS

Seventeen empirical studies and 52 case reports met inclusion criteria. Most focused on sexual dysfunction which was identified as common among this cohort and associated with both psychotic disorders and antipsychotics. The study population was more likely to engage in sexual risk-taking behavior and was at higher risk of sexually transmissible infections than those without psychosis. SRH topics of clinical relevance in older patients with psychosis such as pregnancy, abortion, sexual violence, coercion, sexual identity, and gender were poorly addressed in this younger group. We found empirical studies generally lacked identification and controlling of confounders whilst case reports provided limited description of mental health and SRH outcomes following clinical intervention.

CONCLUSION

Research and clinical practice addressing sexual and reproductive health is needed for young people living with psychosis. To address research gaps future studies should focus on women's health, sexual violence, gender, and sexuality in young people with psychosis.

Structural Features Predict Sexual Trauma and Interpersonal Problems in Borderline Personality Disorder but Not in Controls: A Multi-Voxel Pattern Analysis

Child trauma plays an important role in the etiology of Bordeline Personality Disorder (BPD). Of all traumas, sexual trauma is the most common, severe and most associated with receiving a BPD diagnosis when adult. Etiologic models posit sexual abuse as a prognostic factor in BPD. Here we apply machine learning using Multiple Kernel Regression to the Magnetic Resonance Structural Images of 20 BPD and 13 healthy control (HC) to see whether their brain predicts five sources of traumas: sex abuse, emotion neglect, emotional abuse, physical neglect, physical abuse (Child Trauma Questionnaire; CTQ). We also applied the same analysis to predict symptom severity in five domains: affective, cognitive, impulsivity, interpersonal (Zanarini Rating Scale for Borderline Personality Disorder; Zan-BPD) for BPD patients only. Results indicate that CTQ sexual trauma is predicted by a set of areas including the amygdala, the Heschl area, the Caudate, the Putamen, and portions of the Cerebellum in BPD patients only. Importantly, interpersonal problems only in BPD patients were predicted by a set of areas including temporal lobe and cerebellar regions. Notably, sexual trauma and interpersonal problems were not predicted by structural features in matched healthy controls. This finding may help elucidate the brain circuit affected by traumatic experiences and connected with interpersonal problems BPD suffer from.

Sexual Dysfunction in Schizophrenia: A Narrative Review of the Mechanisms and Clinical Considerations

Psychiatric disorders, in general, have a high prevalence of sexual problems, whether from the psychopathology of the disorder itself, pre-existing or co-morbid sexual disorder or from side effects of the treatment for mental disorders. Many patients report an already existing sexual dysfunction at the onset of diagnosis. The risk association for developing sexual dysfunction in patients with schizophrenia includes antipsychotic use and resulting hyperprolactinemia, age, gender, and disease severity. Medication side effects lead to nonadherence, and relapses lead to structural changes in the brain, treatment resistance, and worsening of symptoms. Findings in certain studies propose serum prolactin and thyroid-stimulating hormone measurement as a tool for assessing patients with schizophrenia for sexual dysfunction. Regarding specific symptoms, females especially reported decreased desire at baseline and galactorrhea after treatment. The findings of this review, therefore, suggest that sexual dysfunction may be present in patients with schizophrenia before starting antipsychotic treatment and that patients, especially those who are female, are likely to develop hyperprolactinemia with antipsychotic treatment. Aripiprazole may be an emergent treatment for sexual dysfunction in those who use antipsychotics. It is important for patients to consider sexual dysfunction prior to prescribing antipsychotics. Since sexual dysfunction can impact a patient’s quality of life and affect treatment adherence, it is important for physicians to be aware and monitor patients for symptoms.
