Proceedings of PRINCETON IV: PDE5 inhibitors and cardiac health symposium.

INTRODUCTION: Prior consensus meetings have addressed the relationship between phosphodiesterase type 5 (PDE5) inhibition and cardiac health. Given significant accumulation of new data in the past decade, a fourth consensus conference on this topic was convened in Pasadena, California, on March 10 and 11, 2023. OBJECTIVES: Our meeting aimed to update existing knowledge, assess current guidelines, and make recommendations for future research and practice in this area. METHODS: An expert panel reviewed existing research and clinical practice guidelines. RESULTS: Key findings and clinical recommendations are the following: First, erectile dysfunction (ED) is a risk marker and enhancer for cardiovascular (CV) disease. For men with ED and intermediate levels of CV risk, coronary artery calcium (CAC) computed tomography should be considered in addition to previous management algorithms. Second, sexual activity is generally safe for men with ED, although stress testing should still be considered for men with reduced exercise tolerance or ischemia. Third, the safety of PDE5 inhibitor use with concomitant medications was reviewed in depth, particularly concomitant use with nitrates or alpha-blockers. With rare exceptions, PDE5 inhibitors can be safely used in men being treated for hypertension, lower urinary tract symptoms and other common male disorders. Fourth, for men unresponsive to oral therapy or with absolute contraindications for PDE5 inhibitor administration, multiple treatment options can be selected. These were reviewed in depth with clinical recommendations. Fifth, evidence from retrospective studies points strongly toward cardioprotective effects of chronic PDE5-inhibitor use in men. Decreased rates of adverse cardiac outcomes in men taking PDE-5 inhibitors has been consistently reported from multiple studies. Sixth, recommendations were made regarding over-the-counter access and potential risks of dietary supplement adulteration. Seventh, although limited data exist in women, PDE5 inhibitors are generally safe and are being tested for use in multiple new indications. CONCLUSION: Studies support the overall cardiovascular safety of the PDE5 inhibitors. New indications and applications were reviewed in depth.

Female Sexual Health: Screening and Evaluation.

Female sexual dysfunction is highly prevalent, affecting 30% to 50% of cisgender women globally. Low sexual desire, sexual arousal disorder, and orgasm disorder affect 10% to 20%, 6% to 20%, and 4% to 14% of women, respectively. Dyspareunia or pain with intercourse affects 8% to 22% of women. Universal screening is recommended; and a thorough medical history and physical examination are the foundations of evaluation and assessment. Laboratory tests and imaging are sometimes warranted, but referral to a sexual medicine expert is suggested if the practitioner is unfamiliar or uncomfortable with treatment.

Princeton IV consensus guidelines: PDE5 inhibitors and cardiac health.

BACKGROUND: In 1999, 1 year after the approval of the first oral phosphodiesterase type 5 (PDE5) inhibitor for the treatment of erectile dysfunction (ED), the first Princeton Consensus Conference was held to address the clinical management of men with ED who also had cardiovascular disease. These issues were readdressed in the second and third conferences. In the 13 years since the last Princeton Consensus Conference, the experience with PDE5 inhibitors is more robust, and recent new data have emerged regarding not only safety and drug-drug interactions, but also a potential cardioprotective effect of these drugs. AIM: In March 2023, an interdisciplinary group of scientists and practitioners met for the fourth Princeton Consensus Guidelines at the Huntington Medical Research Institutes in Pasadena, California, to readdress the cardiovascular workup of men presenting with ED as well as the approach to treatment of ED in men with known cardiovascular disease. METHOD: A series of lectures from experts in the field followed by Delphi-type discussions were developed to reach consensus. OUTCOMES: Consensus was reached regarding a number of issues related to erectile dysfunction and the interaction with cardiovascular health and phosphodiesterase-5 inhibitors. RESULTS: An algorithm based on recent recommendations of the American College of Cardiology and American Heart Association, including the use of computed tomography coronary artery calcium scoring, was integrated into the evaluation of men presenting with ED. Additionally, the issue of nitrate use was further considered in an algorithm regarding the treatment of ED patients with coronary artery disease. Other topics included the psychological effect of ED and the benefits of treating it; the mechanism of action of the PDE5 inhibitors; drug-drug interactions; optimizing use of a PDE5 inhibitors; rare adverse events; potential cardiovascular benefits observed in recent retrospective studies; adulteration of dietary supplements with PDE5 inhibitors; the pros and cons of over-the-counter PDE5 inhibitors; non-PDE5 inhibitor therapy for ED including restorative therapies such as stem cells, platelet-rich plasma, and shock therapy; other non-PDE5 inhibitor therapies, including injection therapy and penile prostheses; the issue of safety and effectiveness of PDE5 inhibitors in women; and recommendations for future studies in the field of sexual dysfunction and PDE5 inhibitor use were discussed. CLINICAL IMPLICATIONS: Algorithms and tables were developed to help guide the clinician in dealing with the interaction of ED and cardiovascular risk and disease. STRENGTHS AND LIMITATIONS: Strengths include the expertise of the participants and consensus recommendations. Limitations included that participants were from the United States only for this particular meeting. CONCLUSION: The issue of the intersection between cardiovascular health and sexual health remains an important topic with new studies suggesting the cardiovascular safety of PDE5 inhibitors.

Testosterone use for hypoactive sexual desire disorder in postmenopausal women.

Testosterone is an important evidence-based therapy for hypoactive sexual desire disorder (HSDD) in postmenopausal women. Clinical practice guidelines based on the most comprehensive meta-analysis of benefits and risks of testosterone therapy to date state that the sole evidence-based indication for testosterone therapy is HSDD in postmenopausal women. The guidelines also provide recommendations regarding identification of patients, dosing, monitoring, and follow-up. This Practice Pearl will discuss evidence-based testosterone therapy for management of HSDD in postmenopausal women.

Symptoms and associated impact in pre- and postmenopausal women with sexual arousal disorder: a concept elicitation study.

BACKGROUND: Approximately 26% of adult women in the United States suffer from female sexual arousal disorder (FSAD), yet little has been done to compare the experience of FSAD in pre- and postmenopausal women, which is critical to enhance the current understanding of FSAD and inform the development and assessment of treatment options for these patient populations. AIM: To explore the experience of condition-associated symptoms and the relative importance of FSAD symptoms, including their severity, bother, and impact, on participants' health-related quality of life (HRQoL) in pre- and postmenopausal women with FSAD. METHODS: In-depth, qualitative, semistructured concept elicitation interviews were conducted with premenopausal (n = 23) and postmenopausal (n = 13) women who were clinically diagnosed with FSAD by a trained sexual medicine clinician. All interviews were audio recorded and transcribed verbatim by a professional transcription company. Thematic analysis was performed with the assistance of NVivo qualitative analysis software. OUTCOMES: Outcomes included qualitative interview data about FSAD symptoms and HRQoL, as well as a comparison between pre- and postmenopausal populations. RESULTS: The most frequently reported symptom in both cohorts was "inability or difficulty with orgasm" (premenopausal, n = 21; postmenopausal, n = 13). The symptom that premenopausal women most desired to have treated was lubrication, and for postmenopausal women, it was a lack of lubrication or wetness and loss of feeling/sensation. In total, 21 of 23 premenopausal women and all 13 postmenopausal women reported a lack of feeling or sensation in the genitals. The most frequently reported HRQoL impact in both groups was decreased confidence. CLINICAL IMPLICATIONS: Results from this study suggest that the manifestation and experience of FSAD are similar in pre- and postmenopausal women and that the unmet need for an FSAD treatment in the postmenopausal population is just as great as that of the premenopausal population. STRENGTHS AND LIMITATIONS: This study involved in-depth qualitative interviews with a relatively small group of women (N = 36) recruited from only 5 study sites across the United States. CONCLUSION: The analysis of qualitative data from the concept elicitation interviews revealed a substantial physical and emotional burden of FSAD, underscoring the need for Food and Drug Administration-approved treatment options for pre- and postmenopausal women with FSAD.

Universal COVID-19 testing and a three-space triage protocol is associated with a nine-fold decrease in possible nosocomial infections in an inpatient psychiatric facility.

In May of 2020, the Substance Abuse and Mental Health Service Administration (SAMSA) issued guidelines for state psychiatric hospitals, recommending that these facilities adopt universal testing for COVID-19 and "three-space" triage protocols for dedicated COVID-19 positive, negative, and quarantine spaces to mitigate the risk of nosocomial infection. The Westchester Behavioral Health Center of New York Presbyterian Hospital (WBHC-NYP) adopted a comprehensive infection control protocol consistent with these recommendations in April, 2020. We reviewed the records of 1,139 patients treated on the inpatient service at WBHC-NYP between March 14th and June 10th, 2020, dates corresponding to the first COVID-19 surge in the New York City metropolitan region. The incidence of detected nosocomial or possible nosocomial infections before and during the implementation of the protocol was 0.096 (16/167), or 0.96 infections per 10 at-risk patients. The incidence of nosocomial or possible nosocomial infections after complete implementation was 0.0110 (2/182), or 1.1 infections per 100 at-risk patients. The difference in incidence between the two time points was statistically significant (p<.0003) and represents a 9-fold decrease.  Our findings support the institutional use of a combined testing and space allocation protocol to mitigate risk of outbreaks in confined settings.

The Interface of COVID-19 and Inpatient Psychiatry: Our Experience and Lessons Learned.

The coronavirus disease 2019 (COVID-19) pandemic presented unprecedented challenges to the provision of inpatient psychiatric care. The nature of the physical plant, programmatic constraints, and the patient population required a rapid and agile approach to problem-solving under conditions of uncertainty and stress. Flexibility in decision-making, excellent communication, an effective working relationship with infection prevention and control experts, and attention to staff morale and support were important elements of successful provision of care to our inpatients. We present our experience, lessons learned, and recommendations should a resurgence of the pandemic or a similar crisis occur.

International Society for the Study of Women's Sexual Health Clinical Practice Guideline for the Use of Systemic Testosterone for Hypoactive Sexual Desire Disorder in Women.

BACKGROUND: The Global Consensus Position Statement on the Use of Testosterone Therapy for Women (Global Position Statement) recommended testosterone therapy for postmenopausal women with hypoactive sexual desire disorder (HSDD). AIM: To provide a clinical practice guideline for the use of testosterone including identification of patients, laboratory testing, dosing, post-treatment monitoring, and follow-up care in women with HSDD. METHODS: The International Society for the Study of Women's Sexual Health appointed a multidisciplinary panel of experts who performed a literature review of original research, meta-analyses, review papers, and consensus guidelines regarding testosterone use in women. Consensus was reached using a modified Delphi method. OUTCOMES: A clinically useful guideline following a biopsychosocial assessment and treatment approach for the safe and efficacious use of testosterone in women with HSDD was developed including measurement, indications, formulations, prescribing, dosing, monitoring, and follow-up. RESULTS: Although the Global Position Statement endorses testosterone therapy for only postmenopausal women, limited data also support the use in late reproductive age premenopausal women, consistent with the International Society for the Study of Women's Sexual Health Process of Care for the Management of HSDD. Systemic transdermal testosterone is recommended for women with HSDD not primarily related to modifiable factors or comorbidities such as relationship or mental health problems. Current available research supports a moderate therapeutic benefit. Safety data show no serious adverse events with physiologic testosterone use, but long-term safety has not been established. Before initiation of therapy, clinicians should provide an informed consent. Shared decision-making involves a comprehensive discussion of off-label use, as well as benefits and risks. A total testosterone level should not be used to diagnose HSDD, but as a baseline for monitoring. Government-approved transdermal male formulations can be used cautiously with dosing appropriate for women. Patients should be assessed for signs of androgen excess and total testosterone levels monitored to maintain concentrations in the physiologic premenopausal range. Compounded products cannot be recommended because of the lack of efficacy and safety data. CLINICAL IMPLICATIONS: This clinical practice guideline provides standards for safely prescribing testosterone to women with HSDD, including identification of appropriate patients, dosing, and monitoring. STRENGTHS & LIMITATIONS: This evidence-based guideline builds on a recently published comprehensive meta-analysis and the Global Position Statement endorsed by numerous societies. The limitation is that testosterone therapy is not approved for women by most regulatory agencies, thereby making prescribing and proper dosing challenging. CONCLUSION: Despite substantial evidence regarding safety, efficacy, and clinical use, access to testosterone therapy for the treatment of HSDD in women remains a significant unmet need.

COVID-19 infection rates in patients referred for psychiatric admission during a regional surge: The case for universal testing.

Some psychiatric hospitals have instituted mandatory COVID-19 testing for all patients referred for admission. Others have permitted patients to decline testing. Little is known about the rate of COVID-19 infection in acute psychiatric inpatients. Characterizing the proportion of infected patients who have an asymptomatic presentation will help inform policy regarding universal mandatory versus symptom-based or opt-out testing protocols. We determined the COVID-19 infection rate and frequency of asymptomatic presentation in 683 consecutively admitted patients during the surge in the New York City region between April 3rd, 2020 and June 8th, 2020. Among these psychiatric inpatients, there was a 9.8 % overall rate of COVID-19 infection. Of the COVID-19 infected patients, approximately 76.1 % (51/67) either had no COVID-19 symptoms or could not offer reliable history of symptoms at the time of admission. Had they not been identified by testing and triaged to a COVID-19 positive unit, they could have infected others, leading to institutional outbreak. These findings provide justification for psychiatric facilities to maintain universal mandatory testing policies, at least until community infection rates fall and remain at very low levels.

International Society for the Study of Women's Sexual Health (ISSWSH) Review of Epidemiology and Pathophysiology, and a Consensus Nomenclature and Process of Care for the Management of Persistent Genital Arousal Disorder/Genito-Pelvic Dysesthesia (PGAD/GPD).

BACKGROUND: Persistent genital arousal disorder (PGAD), a condition of unwanted, unremitting sensations of genital arousal, is associated with a significant, negative psychosocial impact that may include emotional lability, catastrophization, and suicidal ideation. Despite being first reported in 2001, PGAD remains poorly understood. AIM: To characterize this complex condition more accurately, review the epidemiology and pathophysiology, and provide new nomenclature and guidance for evidence-based management. METHODS: A panel of experts reviewed pertinent literature, discussed research and clinical experience, and used a modified Delphi method to reach consensus concerning nomenclature, etiology, and associated factors. Levels of evidence and grades of recommendation were assigned for diagnosis and treatment. OUTCOMES: The nomenclature of PGAD was broadened to include genito-pelvic dysesthesia (GPD), and a new biopsychosocial diagnostic and treatment algorithm for PGAD/GPD was developed. RESULTS: The panel recognized that the term PGAD does not fully characterize the constellation of GPD symptoms experienced by patients. Therefore, the more inclusive term PGAD/GPD was adopted, which maintains the primacy of the distressing arousal symptoms and acknowledges associated bothersome GPD. While there are diverse biopsychosocial contributors, there is a common underlying neurologic basis attributable to spontaneous intense activity of the genito-pelvic region represented in the somatosensory cortex and its projections. A process of care diagnostic and treatment strategy was developed to guide the clinician, whenever possible, by localizing the symptoms as originating in any of five regions: (i) end organ, (ii) pelvis/perineum, (iii) cauda equina, (iv) spinal cord, and (v) brain. Psychological treatment strategies were considered critical and should be performed in conjunction with medical strategies. Pharmaceutical interventions may be used based on their site and mechanism of action to reduce patients' symptoms and the associated bother and distress. CLINICAL IMPLICATIONS: The process of care for PGAD/GPD uses a personalized, biopsychosocial approach for diagnosis and treatment. STRENGTHS AND LIMITATIONS: Strengths and Limitations: Strengths include characterization of the condition by consensus, analysis, and recommendation of a new nomenclature and a rational basis for diagnosis and treatment. Future investigations into etiology and treatment outcomes are recommended. The main limitations are the dearth of knowledge concerning this condition and that the current literature consists primarily of case reports and expert opinion. CONCLUSION: We provide, for the first time, an expert consensus review of the epidemiology and pathophysiology and the development of a new nomenclature and rational algorithm for management of this extremely distressing sexual health condition that may be more prevalent than previously recognized.

The Evolution of the Female Sexual Disorder/Dysfunction Definitions, Nomenclature, and Classifications: A Review of DSM, ICSM, ISSWSH, and ICD.

INTRODUCTION: The 2 most well-known classification systems that include sexual medicine diagnoses are the International Classification of Diseases and Statistics (ICD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM). Sexual medicine experts from international societies representing an array of disciplines have revised and redefined female sexual dysfunctions (FSDs) to reflect current scientific evidence and the state of the art. AIM: To summarize the evidence and interactive and chronological process by which sexual medicine societies' consensus groups developed the current nomenclature, classifications, and definitions for FSDs. METHODS: We review the contributions and collaborations of the Fourth International Consultation in Sexual Medicine (ICSM), the International Society for the Study of Women's Sexual Health (ISSWSH), and the World Association of Sexual Health in conjunction with the World Health Organization. MAIN OUTCOME MEASURES: The ICSM and ISSWSH diagnostic systems are contrasted with the DSM classification. We discuss innovations and strengths; relevant evidence regarding epidemiology, etiology, and risk factors; and key differences. We describe how sexual medicine expertise informed FSD codes in the ICD-11 classification. RESULTS: ICSM and ISSWSH published evidence-based guidelines on the definitions, nomenclature, and diagnostic criteria for FSD that diverge from the DSM psychiatric compendia. These definitions and nomenclature recommend the separation of female sexual desire and arousal disorders, elaborate on subtypes of arousal problems, broaden the scope of sexual pain definitions, and provide a greater understanding of etiologies and risk factors for FSDs. CONCLUSIONS: These collaborations among sexual medicine experts and their role in the ICD-11 development process provide confidence that the ICD-11 Sexual Dysfunction codes are based on current scientific evidence for diagnosing and coding FSDs in clinical settings worldwide, can serve as endpoints in clinical trials, and will provide specificity for treatment outcomes for FSD therapies.

A COVID-19 testing and triage algorithm for psychiatric units: One hospital's response to the New York region's pandemic.

Psychiatric patients are at high risk for contracting COVID-19, and inpatient psychiatric units face substantial risks of institutional outbreaks. Here, the authors describe an algorithm for testing and triage in a large psychiatric facility designed to prevent local COVID-19 transmission. The algorithm is based on expert opinion and clinical experience between March and April of 2020, during which the institution cared for 47 COVID-19 positive psychiatric inpatients. The implementation of the algorithm is designed to mitigate COVID-19 transmission, preserve the safest and least restrictive treatment environment for psychiatric inpatients, and provide a model adaptable to other institutional settings.

Effects of Alcohol Administered With Flibanserin in Healthy Premenopausal Women: A Randomized, Double-Blind, Single-Dose Crossover Study.

INTRODUCTION: Flibanserin is approved in the United States and Canada for the treatment of hypoactive sexual desire disorder in premenopausal women. AIM: The purpose of this trial was to evaluate the safety of concomitant administration of flibanserin with alcohol. METHODS: In this single-center, randomized, double-blind, single-dose, crossover study, participants were randomly assigned to 1 of 12 sequences to receive each of 7 treatments: flibanserin 100 mg or placebo with ethanol 0.2 g/kg, 0.4 g/kg, or 0.6 g/kg, or flibanserin 100 mg only. Treatments were administered using a worst-case approach that included morning dosing and consumption of alcohol within 10 minutes. MAIN OUTCOME MEASURE: The primary end point was the proportion of participants who experienced dizziness, syncope, or hypotension. Safety end points included orthostatic vital signs. RESULTS: The study included 96 premenopausal women (mean age 31 ± 8 years). The incidence of dizziness for ethanol + flibanserin was 39.8% for ethanol 0.6 g/kg, 34.1% for 0.4 g/kg, and 27.4% for 0.2 g/kg compared with 31.1% for flibanserin without ethanol. Based on the available vital signs data, there was no effect of ethanol concentration on orthostatic blood pressure, vertigo, or hypotension; no instances of syncope were observed. The overall incidence of adverse events (AEs) was similar when flibanserin was administered alone (96.7%) or with ethanol (90.5-97.6%). CLINICAL IMPLICATIONS: Consumption of the tested amounts of alcohol (0.2-0.6 g/kg) does not have an additive effect on the AE profile of flibanserin 100 mg in healthy premenopausal women. STRENGTHS & LIMITATIONS: Strengths include the study population (premenopausal women, as indicated for flibanserin) and range of ethanol doses. Limitations include the morning dosing of study medication, which is inconsistent with the bedtime dosing recommended for flibanserin, and the method of handling missing vital sign measurements. CONCLUSION: Co-administration of flibanserin 100 mg with varying doses of ethanol resulted in few AEs of special interest, with no notable alcohol dose response. However, a significantly greater percentage of participants administered flibanserin with 0.6 g/kg and 0.4 g/kg of alcohol were characterized as "Participants in Whom Standing Blood Pressure Was Not Obtained" compared with participants administered flibanserin alone.

Early onset of action with a 17ß-estradiol, softgel, vaginal insert for treating vulvar and vaginal atrophy and moderate to severe dyspareunia.

OBJECTIVE: The softgel 17ß-estradiol (E2) vaginal inserts (4 and 10 µg; Imvexxy; TherapeuticsMD, Boca Raton, FL) are FDA approved for treating moderate to severe dyspareunia associated with postmenopausal vulvar and vaginal atrophy (VVA). The objective here was to determine responder rates at week 2 and whether week-2 findings predicted week-12 responders in the REJOICE trial. METHODS: Postmenopausal women received E2 vaginal inserts 4, 10, or 25 µg, or placebo for 12 weeks. Proportion of responders (having ≥2 of the following: vaginal superficial cells >5%, vaginal pH <5.0, or dyspareunia improvement of ≥1 category) were calculated. Odds ratios (ORs) for positive response at week 12 given a positive response at week 2 were determined in the efficacy evaluable (EE) population. RESULTS: The responder rate (in EE population [n = 695]) was 74% to 82% with E2 inserts versus 24% with placebo at week 2, and 72% to 80% versus 33% at week 12. Positive treatment responses were 9- to 14-fold higher with vaginal E2 than with placebo at week 2, and 5- to 8-fold higher at week 12. Response at week 2 predicted response at week 12 in the total population (OR 13.1; 95% CI, 8.8-19.7) and with active treatment only (OR 7.9; 95% CI, 4.7-13.2). CONCLUSIONS: A high percentage of postmenopausal women with moderate to severe dyspareunia responded with the E2 softgel vaginal insert at week 2, and a positive response at week 2 predicted a positive response at week 12.
