Author/s: 
Shalender Bhasin, Peter J Snyder


In clinical trials involving middle-aged and older men with hypogonadism, testosterone treatment led to improved sexual activity and libido, correction of anemia, and modestly improved energy, mood, and walking ability. (The following key points also refer to findings from clinical trials involving this patient population.)

Testosterone treatment did not improve cognition in men without a previously diagnosed cognitive disorder and did not prevent progression to diabetes in men with prediabetes or improve glycemic control in those with diabetes.

Testosterone treatment did not increase the risk of major cardiovascular events among men with preexisting cardiovascular disease.

Testosterone treatment did not increase the risk of prostate cancer or acute urinary retention and did not worsen lower urinary tract symptoms.

Testosterone treatment was associated with an increased risk of clinical fractures and pulmonary embolism.

The decision to administer testosterone treatment in a man with hypogonadism should be based on the severity of the hypogonadism and an assessment of the potential benefits and risks of treatment.

Daehoon Kim, MD, Jaemin Shim, MD, Eue-Keun Choi, MD

Importance: Data from randomized clinical trials on a long-term anticoagulation strategy for patients after catheter-based ablation for atrial fibrillation (AF) are lacking.

Objective: To evaluate whether discontinuing oral anticoagulant therapy provides superior clinical outcomes compared with continuing oral anticoagulant therapy in patients without documented atrial arrhythmia recurrence after catheter ablation for AF.

Design, setting, and participants: A randomized clinical trial including 840 adult patients (aged 19-80 years) who were enrolled and randomized from July 28, 2020, to March 9, 2023, at 18 hospitals in South Korea. Enrolled patients had at least 1 non-sex-related stroke risk factor (determined using the CHA2DS2-VASc score [range, 0-9]) and no documented recurrence of atrial arrhythmia for at least 1 year after catheter ablation for AF. The CHA2DS2-VASc score is used as an assessment of stroke risk among patients with AF (calculated using point values for congestive heart failure, hypertension, ≥75 years of age, diabetes, stroke or transient ischemic attack, vascular disease, between 65 and 74 years of age, and sex category). The date of final follow-up was June 4, 2025.

Interventions: The patients were randomly assigned in a 1:1 ratio to discontinue oral anticoagulant therapy (n = 417) or continue oral anticoagulant therapy (with direct oral anticoagulants; n = 423).

Main outcomes and measures: The primary outcome was the first occurrence of a composite of stroke, systemic embolism, and major bleeding at 2 years. Individual components of the primary outcome (such as ischemic stroke and major bleeding) were assessed as secondary outcomes.

Results: Of the 840 adults randomized, the mean age was 64 (SD, 8) years, 24.9% were women, the mean CHA2DS2-VASc score was 2.1 (SD, 1.0), and 67.6% had paroxysmal AF. At 2 years, the primary outcome occurred in 1 patient (0.3%) in the discontinue oral anticoagulant therapy group vs 8 patients (2.2%) in the continue oral anticoagulant therapy group (absolute difference, -1.9 percentage points [95% CI, -3.5 to -0.3]; P = .02). The 2-year cumulative incidence of ischemic stroke was 0.3% in the discontinue oral anticoagulant therapy group vs 0.8% in the continue oral anticoagulant therapy group (absolute difference, -0.5 percentage points [95% CI, -1.6 to 0.6]). Major bleeding occurred in 0 patients in the discontinue oral anticoagulant therapy group vs 5 patients (1.4%) in the continue oral anticoagulant therapy group (absolute difference, -1.4 percentage points [95% CI, -2.6 to -0.2]).

Conclusions and relevance: Among patients without documented atrial arrhythmia recurrence after catheter ablation for AF, discontinuing oral anticoagulant therapy resulted in a lower risk for the composite outcome of stroke, systemic embolism, and major bleeding vs continuing direct oral anticoagulant therapy.

Importance: Existing pharmacological treatments for insomnia have significant limitations.

Objective: To assess the effective dose range, safety, and tolerability of the novel selective orexin-2 receptor antagonist seltorexant in insomnia disorder.

Design, setting, and participants: This randomized, double-blind, active- and placebo-controlled, dose-finding, polysomnography study was conducted from November 2017 to April 2019 at 55 sites in 6 countries and analyzed in August 2019. The timeline for submission of this data for publication was impacted by internal strategic decision-making. Adults (aged 18-64 years) and older adults (aged 65-85 years) with insomnia (Insomnia Severity Index score ≥15) and no psychiatric comorbidity were included.

Interventions: Participants were randomized 1:1:1:1:1 to receive nightly oral-seltorexant (5 mg, 10 mg, or 20 mg), placebo, or zolpidem (5-10 mg) for 14 days.

Main outcomes and measures: Primary and key secondary outcomes included the dose-response relationship of night 1 latency to persistent sleep (LPS) and wake after sleep onset over the first 6 hours (WASO-6). Other secondary outcomes included night 13 LPS and WASO-6. Due to asymmetrical distributions of LPS and WASO-6 at baseline, log transformation was applied and results were expressed as back-transformed least-squares mean (LSM) ratios for comparisons between groups.

Results: Overall, 364 participants (mean [SD] age, 57.8 [12.4] years; 246 [67.6%] female) received seltorexant, 5 mg (n = 71), 10 mg (n = 74), or 20 mg (n = 71); placebo (n = 75); or zolpidem (n = 73). The night 1 dose-response relationship for LPS was significant (with trend test t statistics ≥3.99 and adjusted P values <.001 for all 4 prespecified models), with greater improvements in seltorexant, 10 mg and 20 mg, vs placebo (10 mg: LSM ratio, 0.64; 90% CI, 0.51-0.81; 20 mg: LSM ratio, 0.51; 90% CI, 0.41-0.64) and in seltorexant, 20 mg, vs zolpidem (LSM ratio, 0.71; 90% CI, 0.57-0.88). The night 1 dose-response relationship for WASO-6 was also significant, with trend test t statistics ≥3.99 and adjusted P values <.001 for all 4 prespecified models (seltorexant, 10 mg: LSM ratio, 0.68; 90% CI, 0.55-0.85; seltorexant, 20 mg: LSM ratio, 0.60; 90% CI, 0.48-0.74). Night 1 LPS and WASO-6 improvements were maintained on night 13 for seltorexant, 10 mg and 20 mg, but diminished for zolpidem. On night 13, compared with zolpidem, seltorexant, 10 mg and 20 mg, improved LPS by 30% and 28%, respectively, and seltorexant, 20 mg, improved WASO-6 by 31%. Treatment-emergent adverse events (TEAEs) were lower across the combined seltorexant doses (73/216 [33.8%]) relative to placebo (37/75 [49.3%]) and zolpidem (31/73 [42.5%]). Two participants experienced serious TEAEs during the double-blind phase (1 in the seltorexant, 20 mg, group and 1 in the zolpidem group). Three participants in the seltorexant, 5 mg, and 1 in the seltorexant, 20 mg, group experienced asymptomatic electrocardiogram-related TEAEs leading to discontinuation.

Conclusions and relevance: Among participants with insomnia in this study, seltorexant, 10 mg and 20 mg, improved sleep initiation and maintenance throughout 14 days of treatment. Seltorexant was generally well tolerated.

Hemorrhoidal Disease: A Review

Author/s: 
Jean H Ashburn

Importance Hemorrhoidal disease, pathology of the tissue lining of the anal canal, affects approximately 10 million individuals in the US. Hemorrhoidal disease may impair quality of life due to bleeding, pain, anal irritation, and tissue prolapse.

Observations Hemorrhoids are classified as internal, external, or mixed (concurrent internal and external hemorrhoidal disease). Internal hemorrhoids originate above the dentate line, the boundary between the upper and lower anal canal, and may cause rectal bleeding, discomfort, and tissue prolapse from the anal canal. Internal hemorrhoid prolapse is classified as grade I (into anal canal), grade II (beyond the anus with spontaneous reduction), grade III (requiring manual reduction), and grade IV (irreducible). External hemorrhoids, arising below the dentate line, cause rectal pain when engorged or thrombosed. Initial treatment of all hemorrhoidal disease involves increasing intake of dietary fiber and water and avoiding straining during defecation. Phlebotonics (eg, flavonoids [thought to improve venous tone]) reduce bleeding, rectal pain, and swelling, although symptom recurrence reaches 80% within 3 to 6 months after treatment cessation. If dietary modification and phlebotonics are ineffective, grade I to grade III internal hemorrhoidal disease can be treated with office-based interventions. Rubber band ligation—placing a band around the base of hemorrhoid tissue during anoscopy to restrict blood flow—resolves symptoms in 89% of patients, but repeated banding is needed in up to 20%. Sclerotherapy, which induces fibrosis with a sclerosant injection, is efficacious in the short term (weeks to months) among 70% to 85% of patients, but long-term remission occurs in only one-third of patients. Infrared coagulation uses heat to coagulate hemorrhoidal tissue, yielding 70% to 80% success in reducing bleeding and prolapse. Excisional hemorrhoidectomy, for disease unresponsive to office-based therapy or for mixed hemorrhoidal disease, achieves low recurrence (2%-10%), although with longer recovery (9-14 days). External hemorrhoidal disease rarely requires surgery unless acutely thrombosed. Outpatient clot evacuation within 72 hours of onset of a thrombosed external hemorrhoid is associated with decreased pain and reduced risk of repeat thrombosis. Patients presenting more than 72 hours after external hemorrhoid acute thrombosis should receive medical treatment (eg, stool softeners, oral and topical analgesics such as 5% lidocaine).

Conclusions and Relevance Hemorrhoidal disease affects 10 million people in the US. First-line treatment is increased fiber intake, avoidance of straining during defecation, and phlebotonics. In-office rubber band ligation for grade I to III internal hemorrhoid disease is first-line procedural treatment for persistent symptoms despite conservative therapies. Excisional hemorrhoidectomy is recommended for grade III to IV prolapse, thrombosis, or mixed hemorrhoidal disease that does not improve with less invasive approaches.

Millions of Americans affected by Long COVID (LC) report difficulty accessing care and support. One barrier is obtaining a diagnosis. In response, US federal agencies commissioned a National Academies of Sciences, Engineering, and Medicine (NASEM) committee to re-examine the existing federal definitions for LC. The Committee concluded that LC is "an infection-associated chronic condition (IACC) occurring after SARS-CoV-2 infection that is present for at least 3 months as a continuous, relapsing and remitting, or progressive disease state that can present as singular or multiple symptoms and/or diagnosable conditions." The full report was released in June 2024. We briefly highlight features and aspects of the definition that may help clinicians identify those who remain undiagnosed and improve care for all LC patients.

What Is Prostate Cancer?

Author/s: 
Rebecca Voelker, MSJ

Prostate cancer is a common malignancy in older men. Prostate cancer typically affects older men (average age at diagnosis is 67 years) and is more common among Black men than White men.1 More than half of prostate cancer risk is due to genetic factors. Prostate cancer is the second most common cause of cancer in men worldwide, with about 1.5 million cases diagnosed in 2021. In the US, 3.4 million men were living with prostate cancer in 2021.

Addictive Screen Use Trajectories and Suicidal Behaviors, Suicidal Ideation, and Mental Health in US Youths

Author/s: 
Yunyu Xiao, PhD, Yuan Meng, PhD, Timothy T. Brown, PhD

Importance: Increasing child and adolescent use of social media, video games, and mobile phones has raised concerns about potential links to youth mental health problems. Prior research has largely focused on total screen time rather than longitudinal addictive use trajectories.

Objectives: To identify trajectories of addictive use of social media, mobile phones, and video games and to examine their associations with suicidal behaviors and ideation and mental health outcomes among youths.

Design, setting, and participants: Cohort study analyzing data from baseline through year 4 follow-up in the Adolescent Brain Cognitive Development Study (2016-2022), with population-based samples from 21 US sites.

Exposures: Addictive use of social media, mobile phones, and video games using validated child-reported measures from year 2, year 3, and year 4 follow-up surveys.

Main outcomes and measures: Suicidal behaviors and ideation assessed using child- and parent-reported information via the Kiddie Schedule for Affective Disorders and Schizophrenia. Internalizing and externalizing symptoms were assessed using the parent-reported Child Behavior Checklist.

Results: The analytic sample (n = 4285) had a mean age of 10.0 (SD, 0.6) years; 47.9% were female; and 9.9% were Black, 19.4% Hispanic, and 58.7% White. Latent class linear mixed models identified 3 addictive use trajectories for social media and mobile phones and 2 for video games. Nearly one-third of participants had an increasing addictive use trajectory for social media or mobile phones beginning at age 11 years. In adjusted models, increasing addictive use trajectories were associated with higher risks of suicide-related outcomes than low addictive use trajectories (eg, increasing addictive use of social media had a risk ratio of 2.14 [95% CI, 1.61-2.85] for suicidal behaviors). High addictive use trajectories for all screen types were associated with suicide-related outcomes (eg, high-peaking addictive use of social media had a risk ratio of 2.39 [95% CI, 1.66-3.43] for suicidal behaviors). The high video game addictive use trajectory showed the largest relative difference in internalizing symptoms (T score difference, 2.03 [95% CI, 1.45-2.61]), and the increasing social media addictive use trajectory for externalizing symptoms (T score difference, 1.05 [95% CI, 0.54-1.56]), compared with low addictive use trajectories. Total screen time at baseline was not associated with outcomes.

Conclusions and relevance: High or increasing trajectories of addictive use of social media, mobile phones, or video games were common in early adolescents. Both high and increasing addictive screen use trajectories were associated with suicidal behaviors and ideation and worse mental health.

Ovarian Cancer: A Review

Author/s: 
Giuseppe Caruso, MD, S. John Weroha, MD, PhD, William Cliby, MD

Importance: Ovarian cancer is the eighth most common cause of cancer and cancer death in women worldwide. In 2022, ovarian cancer was diagnosed in approximately 324 398 individuals, and 206 839 died of ovarian cancer worldwide. In 2025, it is estimated that 20 890 US women will be diagnosed with ovarian cancer and 12 730 patients will die of ovarian cancer.

Observations: Approximately 90% of ovarian cancers are epithelial malignancies, of which 70% to 80% are high-grade serous ovarian cancers. Less common epithelial subtypes include endometrioid, clear cell, low-grade serous, mucinous, and carcinosarcoma. The median age at diagnosis of ovarian cancer is 63 years. Risk factors include older age, family history of breast or ovarian cancer, endometriosis, and nulliparity. Hereditary factors are associated with 25% of cases, predominantly linked to BRCA1/2 gene variants. At diagnosis, approximately 95% of patients experience nonspecific symptoms, such as abdominal pain, bloating, and urinary urgency and frequency, and about 80% have advanced-stage disease (stage III-IV), including extrapelvic disease, ascites, and abdominal masses. Diagnostic and staging evaluation includes pelvic ultrasound; computed tomography of the chest, abdomen, and pelvis; and serum tumor markers such as carbohydrate antigen 125, carbohydrate antigen 19-9, and carcinoembryonic antigen. First-line treatment for early-stage ovarian cancer, defined as limited to the ovary or fallopian tube (stage I) or confined to the pelvis (stage II), is surgery (hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and lymphadenectomy), followed by adjuvant chemotherapy (carboplatin and paclitaxel). With treatment, early-stage ovarian cancer has a 5-year overall survival of 70% to 95%. Advanced-stage ovarian cancer may be treated with primary cytoreductive surgery (removal of all visible cancer in the abdominal cavity) and adjuvant chemotherapy (carboplatin and paclitaxel) or with neoadjuvant chemotherapy followed by cytoreductive surgery and adjuvant chemotherapy. Most patients with advanced-stage ovarian cancer receive maintenance therapy with bevacizumab (a monoclonal antibody that blocks angiogenesis) and/or poly–adenosine diphosphate ribose polymerase (PARP) inhibitors. With treatment, the 5-year overall survival rate for advanced-stage ovarian cancer is 10% to 40%. However, individuals with BRCA-related gene variants have a 5-year overall survival rate of approximately 70% with PARP inhibitor treatment. Despite an initial remission rate of 80%, approximately 75% of patients with advanced-stage disease have ovarian cancer relapse within 2 years.

Conclusions and Relevance: Approximately 21 000 women are diagnosed with ovarian cancer annually in the US, and approximately 80% have advanced-stage ovarian cancer at diagnosis. First-line treatment of early-stage ovarian cancer is surgery and adjuvant platinum-based chemotherapy. Treatment of advanced-stage ovarian cancer includes cytoreductive surgery, platinum-based chemotherapy, and targeted maintenance therapies such as bevacizumab and/or PARP inhibitors.
