Introduction Premature ejaculation (PE) is the most common male sexual dysfunction affecting men and their partners. Lack of community-based data describing this condition limits understanding of PE and its outcomes. Aim To characterize PE in a large population of men with and without PE using patient-reported outcome (PRO) measures elicited from men and their partners. Methods 4-week, multicenter, observational study of males (≥18 years) and their female partners in monogamous relationships (≥6 months). Screening, baseline, and follow-up visits scheduled at 2-week intervals. Clinicians diagnosed PE utilizing DSM-IV-TR criteria. Intravaginal ejaculatory latency time (IELT), measured by a stopwatch held by the partner, was recorded for each sexual intercourse experience. Subject and partner independently assessed PROs: control over ejaculationand satisfaction with sexual intercourse(0 = very poor to 4 = very good), personal distressand interpersonal difficulty(0 = not at all to 4 = extremely), and severity of PE(0 = none to 3 = severe). Results Of the total study population (N = 1,587), 207 subjects were diagnosed with PE and 1,380 were assigned to the non-PE group. Median IELT (min) was 1.8 (range, 0–41) for PE and 7.3 (range, 0–53) for non-PE subjects (P < 0.0001). More PE vs. non-PE subjects gave ratings of “very poor” or “poor” for control over ejaculation(72% vs. 5%; P < 0.0001) and satisfaction with sexual intercourse(31% vs. 1%; P < 0.0001). More subjects in the PE vs. non-PE group gave ratings of “quite a bit” or “extremely” for personal distress(64% vs. 4%; P < 0.0001) and interpersonal difficulty(31% vs. 1%; P < 0.0001). Subject and partner assessments showed similar patterns and correlated moderately (0.36–0.57). Conclusions PE subjects reported significantly shorter IELT. Overlap in IELT distributions was observed between the PE and non-PE groups, indicating the need for additional PRO measures to characterize PE. Shorter IELT was significantly associated with reduced ejaculatory control and sexual satisfaction and increased distress and interpersonal difficulty.
Objective: This study investigated whether patients with mild to moderately severe dementia or possible Alzheimer's disease (AD) with Mini-Mental State Exam (MMSE) Baseline scores of 10–24 would improve when treated with near-infrared photobiomodulation (PBM) therapy. Background: Animal studies have presented the potential of PBM for AD. Dysregulation of the brain's default mode network (DMN) has been associated with AD, presenting the DMN as an identifiable target for PBM. Materials and methods: The study used 810 nm, 10 Hz pulsed, light-emitting diode devices combining transcranial plus intranasal PBM to treat the cortical nodes of the DMN (bilateral mesial prefrontal cortex, precuneus/posterior cingulate cortex, angular gyrus, and hippocampus). Five patients with mild to moderately severe cognitive impairment were entered into 12 weeks of active treatment as well as a follow-up no-treatment, 4-week period. Patients were assessed with the MMSE and Alzheimer's Disease Assessment Scale (ADAS-cog) tests. The protocol involved weekly, in-clinic use of a transcranial-intranasal PBM device; and daily at-home use of an intranasal-only device. Results: There was significant improvement after 12 weeks of PBM (MMSE, p < 0.003; ADAS-cog, p < 0.023). Increased function, better sleep, fewer angry outbursts, less anxiety, and wandering were reported post-PBM. There were no negative side effects. Precipitous declines were observed during the follow-up no-treatment, 4-week period. This is the first completed PBM case series to report significant, cognitive improvement in mild to moderately severe dementia and possible AD cases. Conclusions: Results suggest that larger, controlled studies are warranted. PBM shows potential for home treatment of patients with dementia and AD.
OBJECTIVE To evaluate the reliability and validity of the Premature Ejaculation Profile (PEP), a self‐reported outcome instrument for evaluating domains of PE and its treatment, comprised of four single‐item measures, a profile, and an index score. SUBJECTS AND METHODS Data were from men participating in observational studies in the USA (PE, 207 men; non‐PE, 1380) and Europe (PE, 201; non‐PE, 914) and from men with PE (1238) participating in a phase III randomized, placebo‐controlled clinical trial of dapoxetine. The PEP contains four measures: perceived control over ejaculation, personal distress related to ejaculation, satisfaction with sexual intercourse, and interpersonal difficulty related to ejaculation, each assessed on five‐point response scales. Test‐retest reliability, known‐groups validity, and ability to detect a patient‐reported global impression of change (PGI) in condition were evaluated for the individual PEP measures and a PEP index score (the mean of all four measures). Profile analysis was conducted using multivariate analysis of variance. RESULTS All PEP measures showed acceptable reliability (intraclass correlation coefficients ranged from 0.66 to 0.83) and mean scores for all measures differed significantly between PE and non‐PE groups (P < 0.001). Men who reported a reduction in PE with treatment in the phase III trial had significantly greater scores on each of the four measures. The PEP profiles of men with and without PE differed significantly (P < 0.001) in both observational studies; higher levels of PGI were associated with higher PEP profiles (P < 0.001). The PEP index score also showed acceptable reliability and was significantly different between the PE and non‐PE groups (P < 0.001). Men who reported an improvement in PE with treatment in the phase III trial had significantly greater PEP index scores. In the phase III trial, nausea was the most common adverse event with dapoxetine. CONCLUSION The PEP provides a reliable, valid, and interpretable measure for use in monitoring outcomes of men with PE.
BF-Diary items are generally reliable and valid assessments for OIC research. Specifically, number of SBM is a valid measure for differentiating opioid-treated patients with and without constipation.
BackgroundMulticentric Castleman’s disease (MCD) is a rare lymphoproliferative disorder driven by dysregulated interleukin-6 production. MCD has a poor prognosis, and treatment is generally noncurative and aimed at symptom relief. Siltuximab is a novel, monoclonal interleukin-6 antibody recently shown to be effective in a registration clinical trial. MCD symptoms, such as fatigue, pain, and weakness, are most appropriately quantified using patient-reported outcome (PRO) measures. We assessed the effect of siltuximab on patient perception of symptoms, functional status, and wellbeing using PRO instruments.MethodsWe analyzed results of a randomized, double-blind trial comparing siltuximab 11 mg/kg every 3 weeks with placebo to treat MCD. Subjects (N = 79) completed the recently developed MCD–Symptom Scale (MCD–SS), the Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT–Fatigue) scale, and the Short Form (SF)-36 at predetermined time points throughout the treatment period. Scores were compared at baseline and over time between the treatment arms and PRO instruments.ResultsAt baseline, the mean number of symptoms reported was 9.2 (standard deviation 3.76) out of 16 total, as measured by the MCD–SS. Fatigue was a key symptom across all PRO instruments. Siltuximab-treated subjects reported early improvements in symptoms compared with subjects in the placebo arm on both the MCD–SS and FACIT–Fatigue scale. Statistically significant improvements in five SF-36 domains were observed in siltuximab-treated patients, namely role physical, role emotional, vitality, bodily pain, and mental health.ConclusionsPatients with MCD commonly report impairments in functioning, wellbeing, and fatigue at baseline. Siltuximab-treated patients reported significant improvements in these outcomes after treatment.Electronic supplementary materialThe online version of this article (doi:10.1007/s40271-015-0120-5) contains supplementary material, which is available to authorized users.
