RESUMEN

BACKGROUND: Erectile dysfunction (ED), premature ejaculation (PE), and low libido (LL) are reported as the most common male sexual dysfunctions. OBJECTIVE: To evaluate the prevalence of ED, PE, and LL and associations with lifestyle risk factors and comorbidities in middle-aged men. MATERIALS AND METHODS: This study included a population-based random sample of 2500 50-year-old men who completed validated questionnaires, including the International Index of Erectile Function, the Erection Hardness Score, the Sexual Complaints Screener, and further questionnaires. Multiple logistic regression of outcomes ED, PE, and LL was used to model the association with explanatory factors. RESULTS: The prevalence of at least one sexual dysfunction was 30%. 21%, 5.2%, and 7.2% of men had ED, PE, and LL, respectively. The risk of ED increased with PE (odds ratio [OR]: 1.94, 95% confidence interval [95%CI]: 1.22-3.08), LL (OR: 2.04, 95%CI: 1.26-3.29), higher waist circumference (OR: 2.23, 95%CI: 1.67-2.96), and lower urinary tract symptoms (LUTS) (OR: 1.88, 95%CI: 1.39-2.55), partnership was associated with a lower risk (OR: 0.57, 95%CI: 0.39-0.85). The risk of PE increased with ED (OR: 1.94, 95%CI: 1.23-3.07), partnership (OR:5.42, 95%CI: 1.30-22.60), depression (OR: 2.37, 95%CI: 1.09-5.14), and LUTS (OR: 2.42, 95%CI: 1.52-3.87), and decreased with physical activity (OR: 0.44, 95%CI: 0.21-0.93). The risk of LL increased with ED (OR: 2.09, 95%CI: 1.31-3.34) and poorer self-rated health (OR: 2.97, 95%CI: 1.54-5.71). DISCUSSION AND CONCLUSIONS: Roughly one in three 50-year-old men experience some form of sexual dysfunction and risk factors identified in this study underline the multifactorial nature of ED, PE, and LL. Many risk factors are modifiable which underlines the role of patient education. Modifiable risk factors should be addressed in patient education and men should take active measures to remove the risk posed by these factors.

RESUMEN

Conducting a well-powered and adequately controlled clinical trial in children is often challenging. Bayesian approaches are an attractive option for addressing such challenges as they provide a quantitatively rigorous and integrated framework that makes use of current control data to check and borrow information from historical control data. However various practical concerns and related statistical issues emerge when implementing such Bayesian borrowing approaches. In this manuscript we use a motivating case study to discuss a rigorous stepwise approach on how to address those issues within the Bayesian framework. Specifically, a comprehensive quantitative framework is proposed to assess the extent, synergy, and impact of borrowing. Steps on computing the measures to interpret borrowing are illustrated. Those measures can further help to determine whether additional discounting of external information is necessary.

RESUMEN

BACKGROUND: Due to easy online accessibility of pornography its consumption is popular among adolescents and young adults. Considering recently developed frameworks on the effects of sexual media, we assessed how increased consumption of pornography is associated with the experience of certain aspects of offline and online sexual activity in German medical students. METHODS: Between April 2018 and March 2020 medical students from the Technical University of Munich in Germany were anonymously surveyed with regards to their sexual behavior, consumption of pornography, and use of social media. 468 students (female: n = 293; male: n = 175) were included in the current analysis. Data was analyzed using simple and multiple Poisson regression analysis. RESULTS: Only 7.3% of female students but the majority of male students (79.1%) consumed pornography more than 4 times in the last 4 weeks. Female and male students who reported to be inspired by pornography (female: 52.0%, male: 74.6%) and who have enjoyed the experience of anal intercourse in their life (female: 17.1%, male: 32.2%) consumed pornography more frequently. Female students who have experienced a "threesome" (9.0%), have sent erotic pictures of themselves (33.5%), or use social media in their dating life (27.6%) consumed pornography more frequently. Male students who did not experience a sexual transmitted disease (82.9%) and did not cheat on their partner (68.0%) consumed pornography more frequently (results of multiple Poisson regression analysis; all p < 0.05). CONCLUSIONS: Many students consider pornography as inspiration for their sex life and frequent consumption of pornography seems to be associated with gender specific characteristics congruent with short-term sexual quality. The desire of adolescents and young adults for practical information about sexual intercourse should be addressed openly and a proper understanding of the sexuality shown in pornography should be taught.

RESUMEN

Purpose: To assess efficacy of adalimumab versus placebo in patients with active or inactive noninfectious intermediate, posterior, or panuveitis across different etiologies.Methods: VISUAL I (V-I) and VISUAL II (V-II) clinical trials included adults with active or inactive uveitis, respectively, randomized to receive adalimumab or placebo. In a post hoc subgroup analysis, time to treatment failure (TTF) starting at week 6 (V-I) or week 2 (V-II) was analyzed using the Kaplan-Meier method. Hazard ratios (HR) for TTF with 95% CI were calculated with Cox proportional hazards regression.Results: The analysis included 217 V-I patients and 226 V-II patients. Treatment failure occurred later and risk was significantly lower in patients with idiopathic uveitis receiving adalimumab versus those receiving placebo in V-I (HR = 0.50 [CI, 0.30-0.84]; P = .006) and V-II (HR = 0.43 [CI, 0.22-0.83]; P = .010).Conclusions: Treatment failure risk was lower in patients with idiopathic noninfectious uveitis receiving adalimumab versus those receiving placebo.

RESUMEN

Relative potency assays for biological therapeutics require statistical evaluation to demonstrate similarity between the dose-response curves of a reference standard and the test samples. We developed an equivalence testing approach that can be utilized for the complete potency assay life cycle, from early development until commercialization. This approach was based on the use of generic equivalence margins to enable equivalence testing at the beginning of assay development, when the body of assay-specific data is still very limited. Generic equivalence margins for equivalence testing of four-parameter logistic curve fits were established for bioassays and binding assays spanning a variety of designs, formats, and read-outs. We also established that equivalence testing using ratios of the reference standard and test sample was superior to equivalence testing using absolute differences. Based on a large body of historical data, generic equivalence margins were determined for the curve upper asymptote, slope, and dynamic range. Furthermore, we developed a road map to guide the implementation of generic or assay-specific margins to ensure the appropriate data analysis approach is being applied during the assay life cycle.

RESUMEN

PURPOSE: To evaluate long-term efficacy and safety of extended treatment with adalimumab in patients with noninfectious intermediate, posterior, or panuveitis. DESIGN: Open-label, multicenter, phase 3 extension study (VISUAL III). PARTICIPANTS: Adults who had completed a randomized, placebo-controlled phase 3 parent trial (VISUAL I or II) without treatment failure (inactive uveitis) or who discontinued the study after meeting treatment failure criteria (active uveitis). METHODS: Patients received subcutaneous adalimumab 40 mg every other week. Data were collected for ≤ 362 weeks. Adverse events (AEs) were recorded until 70 days after the last dose. MAIN OUTCOME MEASURES: Long-term safety and quiescence; other efficacy variables included inflammatory lesions, anterior chamber cell and vitreous haze grade, macular edema, visual acuity, and dose of uveitis-related systemic corticosteroids. RESULTS: At study entry, 67% of patients (283/424) showed active uveitis and 33% (141/424) showed inactive uveitis; 60 patients subsequently met exclusion criteria, and 364 were included in the intention-to-treat analysis. Efficacy variables were analyzed through week 150, when approximately 50% of patients (214/424) remained in the study. Patients showing quiescence increased from 34% (122/364) at week 0 to 85% (153/180) at week 150. Corticosteroid-free quiescence was achieved by 54% (66/123) and 89% (51/57) of patients with active or inactive uveitis at study entry. Mean daily dose of systemic corticosteroids was reduced from 9.4 ± 17.1 mg/day at week 0 (n = 359) to 1.5 ± 3.9 mg/day at week 150 (n = 181). The percentage of patients who achieved other efficacy variables increased over time for those with active uveitis at study entry and was maintained for those with inactive uveitis. The most frequently reported treatment-emergent AEs of special interest were infections (n = 275; 79 events/100 patient-years [PY]); AEs and serious AEs occurred at a rate of 396 events/100 PY and 15 events/100 PY, respectively. CONCLUSIONS: Long-term treatment with adalimumab led to quiescence and reduced corticosteroid use for patients who entered VISUAL III with active uveitis and led to maintenance of quiescence for those with inactive uveitis. AEs were comparable with those reported in the parent trials and consistent with the known safety profile of adalimumab.

RESUMEN

Importance: Red blood cell transfusions are commonly administered to infants weighing less than 1000 g at birth. Evidence-based transfusion thresholds have not been established. Previous studies have suggested higher rates of cognitive impairment with restrictive transfusion thresholds. Objective: To compare the effect of liberal vs restrictive red blood cell transfusion strategies on death or disability. Design, Setting, and Participants: Randomized clinical trial conducted in 36 level III/IV neonatal intensive care units in Europe among 1013 infants with birth weights of 400 g to 999 g at less than 72 hours after birth; enrollment took place between July 14, 2011, and November 14, 2014, and follow-up was completed by January 15, 2018. Interventions: Infants were randomly assigned to liberal (n = 492) or restrictive (n = 521) red blood cell transfusion thresholds based on infants' postnatal age and current health state. Main Outcome and Measures: The primary outcome, measured at 24 months of corrected age, was death or disability, defined as any of cognitive deficit, cerebral palsy, or severe visual or hearing impairment. Secondary outcome measures included individual components of the primary outcome, complications of prematurity, and growth. Results: Among 1013 patients randomized (median gestational age at birth, 26.3 [interquartile range {IQR}, 24.9-27.6] weeks; 509 [50.2%] females), 928 (91.6%) completed the trial. Among infants in the liberal vs restrictive transfusion thresholds groups, respectively, incidence of any transfusion was 400/492 (81.3%) vs 315/521 (60.5%); median volume transfused was 40 mL (IQR, 16-73 mL) vs 19 mL (IQR, 0-46 mL); and weekly mean hematocrit was 3 percentage points higher with liberal thresholds. Among infants in the liberal vs restrictive thresholds groups, the primary outcome occurred in 200/450 (44.4%) vs 205/478 (42.9%), respectively, for a difference of 1.6% (95% CI, -4.8% to 7.9%; P = .72). Death by 24 months occurred in 38/460 (8.3%) vs 44/491 (9.0%), for a difference of -0.7% (95% CI, -4.3% to 2.9%; P = .70), cognitive deficit was observed in 154/410 (37.6%) vs 148/430 (34.4%), for a difference of 3.2% (95% CI, -3.3% to 9.6%; P = .47), and cerebral palsy occurred in 18/419 (4.3%) vs 25/443 (5.6%), for a difference of -1.3% (95% CI, -4.2% to 1.5%; P = .37), in the liberal vs the restrictive thresholds groups, respectively. In the liberal vs restrictive thresholds groups, necrotizing enterocolitis requiring surgical intervention occurred in 20/492 (4.1%) vs 28/518 (5.4%); bronchopulmonary dysplasia occurred in 130/458 (28.4%) vs 126/485 (26.0%); and treatment for retinopathy of prematurity was required in 41/472 (8.7%) vs 38/492 (7.7%). Growth at follow-up was also not significantly different between groups. Conclusions and Relevance: Among infants with birth weights of less than 1000 g, a strategy of liberal blood transfusions compared with restrictive transfusions did not reduce the likelihood of death or disability at 24 months of corrected age. Trial Registration: ClinicalTrials.gov Identifier: NCT01393496.

RESUMEN

BACKGROUND: Penile rehabilitation after nerve-sparing radical prostatectomy (nsRP) improves the functional outcome, i.e., erectile function and urinary continence. Masturbation as a concept of penile rehabilitation has been practically not investigated. The aim of this observational and explorative study was to evaluate the association between masturbation and the recovery of the functional outcome in patients after nsRP. METHODS: Patients after nsRP (11/2013-3/2016) with preoperative International Erectile Function Score-Erectile Function (IIEF-EF) of ≥22 and/or Erection Hardness Score (EHS) of ≥3 without neo- or adjuvant therapy were included in this analysis. Patients were classified according to their masturbation behavior (yes: m; no: nm). Chi-square tests were used to test for association between masturbation and functional outcome. The main outcome measures were rates of erectile function, morning erections, and urinary continence 6, 12, 24, and 36 months after nsRP. RESULTS: A total of 250 preoperatively potent patients with median age of 63.8 years (1st, 3rd quartile: 59.1, 69.6) at nsRP were included. After 24 months, m-patients had a numerically higher rate of moderate to good erectile function compared to nm-patients (47.5% vs. 37.5%; P=0.193) and had morning erections more often than nm-patients (54.6% vs. 34.9%; P=0.011). Urinary continence rate 12 months after nsRP was higher compared to nm-patients (12 months: 83.1% vs. 70.2%; P=0.042). CONCLUSIONS: Masturbation might be a promising approach of both erectile function and urinary continence recovery, and patients could be encouraged to masturbate after nsRP. However, due to the study design, causality cannot be concluded. Thus, masturbation as a possible concept of penile rehabilitation warrants further investigation.

RESUMEN

PURPOSE: To determine whether fatal family history (FFH) or mode of inheritance in prostate cancer (PCa) has an impact on long-term outcomes following radical prostatectomy (RP). METHODS: 1076 PCa patients after RP with at least one deceased first-degree relative with PCa were included and stratified by FFH (four subgroups: fraternal, paternal, multiple, and none) and by mode of inheritance (two subgroups: male to male, non-male to male). We compared clinicopathological characteristics between subgroups with Fisher's exact or Chi-square tests. Biochemical recurrence-free survival (BRFS) and cancer-specific survival (CSS) were analyzed using the method of Kaplan and Meier. Simple and multiple Cox regression with backward elimination were performed to select prognostic factors for BRFS and CSS. RESULTS: Median age at surgery was 63.3 (range 35.9-79.4) years. The overall Kaplan-Meier estimated BRFS rate at 10 and 15 years was 65.6% and 57.0%, respectively. The overall Kaplan-Meier estimated CSS rate at 10 and 15 years was 98.1% and 95.7%, respectively. Neither FFH nor mode of inheritance were factors associated with worse BRFS. However, in multiple Cox regression, paternal FFH was an important prognostic factor for a better CSS (HR 0.19, CI 0.05-0.71, p = 0.014) compared to non-FFH. CONCLUSION: FFH and mode of inheritance do not seem to be prognostic factors of worse long-term outcomes following RP. Rather, a paternal FFH was associated with a better CSS; however, the reasons remain unclear. Nevertheless, patients after RP and FFH could be reassured that their own PCa diagnosis is not associated with a worse long-term outcome.

RESUMEN

INTRODUCTION: In the last century, there have been major changes within the population structure in Germany. The aim of this study was to determine the impact of a changing population structure on identification of familial prostate cancer (PCa), and to investigate how many and which types of other cancers have occurred in patients and their first-degree relatives. MATERIALS AND METHODS: A total of 19,540 patients were evaluated in a prospectively collected PCa family database and divided into four birth cohorts: 1925-1934 (cohort A), 1935-1944 (cohort B), 1945-1954 (cohort C), and 1955-1964 (cohort D). Other primary cancers and cancers of first-degree relatives were evaluated. RESULTS: The percentage of PCa patients with ≥2 sons declined (A: 28.9% to D: 21.6%). The percentage of patients whose fathers lived for ≥65 years increased (B: 64.2% to D: 73.0%). Malignancies of the skin, the urinary tract, and the lymphoid/hematopoietic tissue were more common in patients with a positive first-degree PCa family history and their first-degree relatives. Additionally, first-degree relatives reported more often neoplasms of respiratory/intrathoracic organs and the female breast. CONCLUSIONS: A small family size, an early deceased father, and a high number of sporadic cases complicate the identification of familial PCa patients. Thus, a detailed family history should also include unaffected first-degree relatives to avoid any misclassification. Findings of other primary cancers in patients and their relatives warrant further investigation.

RESUMEN

BACKGROUND: Non-infectious uveitis (NIU) is an immune-mediated disease with clinical symptoms such as eye pain, redness, floaters, and light sensitivity. NIU is one of the leading causes of preventable blindness. OBJECTIVE: This review describes current and emerging therapies for NIU. METHODS: PubMed searches were conducted using the terms uveitis, therapy, corticosteroids, immunomodulators, biologics, intravitreal injections, intraocular implants, and adverse events deemed relevant if they presented data relating to prevalence, diagnosis, and treatment of uveitis. RESULTS: Diagnosis and management of NIU may require collaboration among different healthcare providers, including ophthalmologists and rheumatologists. Although many patients with NIU respond to corticosteroid (CS) therapy, long-term CS use can be associated with potentially severe adverse events. Localized CS therapies have been developed to reduce adverse events; however, some intravitreal injections and intraocular implants were linked to elevated intraocular pressure and cataracts. CS-sparing therapies such as biologics have demonstrated efficacy and safety while reducing CS burden. Biologics targeting tumor necrosis factor provide CS-sparing options for patients with NIU. Additional studies are needed to address long-term efficacy and safety of biologics targeting IL-6 and inhibitors of JAK/STAT. CONCLUSION: Biologics, JAK/STAT inhibitors, and improved localized therapies may provide additional options for patients with NIU.

RESUMEN

INTRODUCTION: Although low sexual desire is 1 of the most common sexual dysfunctions in men, there is a lack of studies investigating associated factors in large, population-based samples of middle-aged men. AIM: To survey the prevalence of low sexual desire in a population-based sample of 45-year-old German men and to evaluate associations with a broad set of factors. METHODS: Data were collected between April 2014-April 2016 within the German Male Sex-Study. Participants were asked to fill out questionnaires about 6 sociodemographic, 5 lifestyle, and 8 psychosocial factors, as well as 6 comorbidities and 4 factors of sexual behavior. Simple and multiple logistic regressions were used to assess potential explanatory factors. MAIN OUTCOME MEASURES: We found a notable prevalence of low sexual desire in middle-aged men and detected associations with various factors. RESULTS: 12,646 men were included in the analysis, and prevalence of low sexual desire was 4.7%. In the multiple logistic regression with backward elimination, 8 of 29 factors were left in the final model. Men having ≥2 children, higher frequency of solo-masturbation, perceived importance of sexuality, and higher sexual self-esteem were less likely to have low sexual desire. Premature ejaculation, erectile dysfunction, and lower urinary tract symptoms were associated with low sexual desire. CLINICAL IMPLICATIONS: Low sexual desire is common in middle-aged men, and associating factors that can potentially be modified should be considered during assessment and treatment of sexual desire disorders. STRENGTHS & LIMITATIONS: The strength of our study is the large, population-based sample of middle-aged men and the broad set of assessed factors. However, because of being part of a prostate cancer screening trial, a recruiting bias is arguable. CONCLUSION: Our study revealed that low sexual desire among 45-year-old men is a common sexual dysfunction, with a prevalence of nearly 5% and might be affected by various factors, including sociodemographic and lifestyle factors, as well as comorbidities and sexual behavior.

RESUMEN

BACKGROUND: Erectile dysfunction (ED) is a common public health issue with a significant impact on quality of life. The associations between ED and several risk factors have been reported previously. The continuously increasing incidence of these factors is contributing to the increasing prevalence of ED. AIM: To assess ED prevalence and severity in a representative sample of 45-year-old German men and to analyze the association with risk factors (lifestyle risk factors/comorbidities). METHODS: Data were collected within the German Male Sex-Study. Randomly selected 45-year-old men were invited. A total of 10,135 Caucasian, heterosexual, sexually active men were included in this analysis. The self-reported prevalence of ED was assessed using the Erectile Function domain of the International Index of Erectile Function. Risk factors for ED were ascertained using self-report questionnaires. An anamnesis interview and a short physical examination were performed. MAIN OUTCOME MEASURE: ED prevalence and severity were evaluated in a cross-sectional design. The associations of ED with comorbidities (eg, depression, diabetes, hypertension, lower urinary tract symptoms) and lifestyle factors (ie, smoking, obesity, central obesity, physical inactivity, and poor self-perceived health-status) were analyzed by logistic regression. RESULTS: The overall prevalence of ED was 25.2% (severe, 3.1%; moderate, 9.2%; mild to moderate, 4.2%; mild, 8.7%). Among the men with ED, 48.8% had moderate or severe symptoms. ED prevalence increased with the number of risk factors, to as high as 68.7% in men with 5-8 risk factors. In multiple logistic regression with backward elimination, the strongest associations with ED were found for depression (odds ratio [OR] = 1.87), poor self-perceived health status (OR = 1.72), lower urinary tract symptoms (OR = 1.68), and diabetes (OR = 1.38). CONCLUSION: One out of 4 men already had symptoms of ED at age 45. Almost one-half of the men with ED had moderate to severe symptoms. ED was strongly associated with each analyzed risk factor, and the prevalence and severity of ED increased with an increasing number of risk factors. Hallanzy J, Kron M, Goethe VE, et al.

RESUMEN

PURPOSE: Report global adalimumab safety and efficacy outcomes in patients with non-infectious uveitis. METHODS: Adults with non-infectious intermediate, posterior, or panuveitis were randomized 1:1 to receive placebo or adalimumab in the VISUAL I (active uveitis) or VISUAL II (inactive uveitis) trials. Integrated global and Japan substudy results are reported. The primary endpoint was time to treatment failure (TF). RESULTS: In the integrated studies, TF risk was significantly reduced (hazard ratio [95% CI]) with adalimumab versus placebo (VISUAL I: HR = 0.56 [0.40-0.76], p < 0.001; VISUAL II: HR = 0.52 [0.37-0.74], p < 0.001). In Japan substudies, no consistent trends were observed between groups (VISUAL I: HR = 1.20 [0.41-3.54]; VISUAL II: HR = 0.45 [0.20-1.03]). Adverse event rates were similar between treatment groups in both studies (854 to 1063 events/100 participant-years). CONCLUSIONS: Adalimumab lowered time to TF versus placebo in the integrated population; no consistent trends were observed in Japan substudies. Safety results were consistent between studies.

RESUMEN

PURPOSE: To evaluate safety and efficacy of adalimumab in patients with noninfectious intermediate, posterior, or panuveitis. DESIGN: Phase 3, open-label, multicenter clinical trial extension (VISUAL III). PARTICIPANTS: Adults meeting treatment failure (TF) criteria or who completed VISUAL I or II (phase 3, randomized, double-masked, placebo-controlled) without TF. METHODS: Patients received adalimumab 40 mg every other week. Interim follow-up data were described from VISUAL III weeks 0 through 78. MAIN OUTCOME MEASURES: Disease quiescence, steroid-free quiescence, active inflammatory chorioretinal/retinal vascular lesions, anterior chamber cell grade, vitreous haze grade, best-corrected visual acuity (BCVA), and corticosteroid dose. Binary data were reported using nonresponder imputation (NRI), continuous data using last observation carried forward and as-observed analysis, and corticosteroid dose using observed-case analysis. Adverse events (AEs) were reported from first adalimumab dose in VISUAL III through interim cutoff. RESULTS: Of 424 patients enrolled, 371 were included in intent-to-treat analysis. At study entry, 242 of 371 (65%) patients had active uveitis; 60% (145/242, NRI) achieved quiescence at week 78, and 66% (95/143, as-observed) of those were corticosteroid free. At study entry, 129 of 371 (35%) patients had inactive uveitis; 74% (96/129, NRI) achieved quiescence at week 78, and 93% (89/96, as-observed) of those were corticosteroid free. Inflammatory lesions, anterior chamber grade, and vitreous haze grade showed initial improvement followed by decline in patients with active uveitis and remained stable in patients with inactive uveitis. BCVA improved in patients with active uveitis from weeks 0 to 78 (0.27 to 0.14 logMAR; left and right eyes; as-observed) and remained stable in patients with inactive uveitis. Mean corticosteroid dose decreased from 13.6 mg/day (week 0) to 2.6 mg/day (week 78) in patients with active uveitis and remained stable in those with inactive uveitis (1.5-1.2 mg/day). AEs (424 events/100 patient-years) and serious AEs (16.5 events/100 patient-years) were comparable with previous VISUAL trials. CONCLUSIONS: Patients with active uveitis at study entry who received adalimumab therapy were likely to achieve quiescence, improve visual acuity, and reduce their daily uveitis-related systemic corticosteroid use. Most patients with inactive uveitis at study entry sustained quiescence without a systemic corticosteroid dose increase. No new safety signals were identified.

RESUMEN

PURPOSE: We aimed to determine if family history (FH) of prostate cancer (PC) influenced cancer control after radical prostatectomy (RP). METHODS: Patients were evaluated in a prospectively-collected PC family database: The focus was on hereditary prostate cancer (HPC) defined by Johns Hopkins criteria and sporadic prostate cancer (SPC), rigorously defined by absence of prostate cancer in ≥ 2 brothers aged ≥ 60 years. Additionally, patients with first-degree (FPC) and non-first-degree PC (non-FPC) were assessed. Endpoints were biochemical recurrence-free survival (BRFS) and prostate cancer-specific survival (CSS). Finally, clinico-pathological characteristics were compared and multiple proportional hazards regression was used to identify prognostic factors. RESULTS: In total 11,654 patients were included (807 HPC, 2251 FPC, 8072 non-FPC and 524 SPC). Familial imposition (HPC/FPC) was associated with a younger age at diagnosis. Thus, HPC patients were diagnosed 2.9 years earlier than SPC patients with more locally advanced tumors (≥ pT3). With a median follow up of 6.2 years (range 0-31.5) BRFS was significantly different when stratified by FH. In pairwise analyses BRFS differed significantly for HPC compared to SPC (HR = 1.27). Consecutively FH was identified as prognostic factor for BRFS (p = 0.021) together with age, PSA, pathologic characteristics and adjuvant androgen deprivation. Analyses of CSS did not show a difference. CONCLUSION: Patients with FH of PC are likely to be diagnosed earlier and present a higher proportion of locally advanced disease. In addition, men with FH are at higher risk of biochemical recurrence after surgery but reveal similar outcomes regarding prostate cancer-specific survival.

RESUMEN

PURPOSE: To determine whether disorganization of retinal inner layers (DRIL) assessed by spectral-domain optical coherence tomography (SDOCT) correlates with visual acuity (VA) in eyes with uveitic cystoid macular edema (CME). DESIGN: Secondary analysis of randomized clinical trial data. METHODS: Fifty-six eyes of 42 patients with uveitic CME were prospectively imaged as part of the VISUAL-1 trial (Clinicaltrials.gov identifier NCT01138657). Central subfield thickness (CFT), horizontal and vertical extent of DRIL, foveal DRIL (>500 µm DRIL) hyperreflective foci (HRF), average and largest area of intraretinal (IR) cysts, and extent of disruption of external limiting membrane (ELM) and ellipsoid zone (EZ) were determined within the 1-mm central subfield and correlated with VA at baseline and follow-up visits. RESULTS: Regression analysis adjusted for clustered observations was used to examine the association between OCT morphologic parameters and VA. Across all visits (n = 168), significant associations were found for CFT (0.080 per 100 µm, P < .001), foveal DRIL (0.170, P < .001), horizontal DRIL length (0.055 per 100 µm, P < .001), vertical DRIL extent (0.001, P = .005), total area of IR cysts (0.204 per mm2, P < .001), area of largest IR cyst (1.407 per mm2, P < .001), presence of HRF (P = .026), and EZ disruption (0.042 per 100 µm, P = .02). ELM disruption did not show a significant association with VA (-0.013 per 100 µm, P = .61). CONCLUSION: DRIL is a robust and easily obtained surrogate marker of VA in participants with current or resolved uveitic CME. CFT, DRIL, IR cyst area, EZ disruption, and HRF had a strong association with VA.

RESUMEN

Statistical sample size calculation is essential when planning animal experiments in basic medical research. Usually, such trials involve the testing of multiple hypotheses, and interpreting them in a confirmative manner would require the appropriate adjustment of the Type 1 error. This has to be taken into account as early as possible during sample size estimation - otherwise, all the results obtained would be exploratory, i.e. without cogency. In this paper, the concept of gatekeeping is introduced, along with alternative approaches for Type 1 error adjustment. The application of gatekeeping to the calculation of sample size is demonstrated by using data sets from case studies. Overall, the evaluation of these examples showed that gatekeeping is able to keep the required number of animals comparatively small. In contrast to exploratory planning, which led to the lowest sample sizes, gatekeeping suggested a mean increase of 12% in sample size, while conservative Bonferroni adjustment raised the sample size by 34% on average. Gatekeeping is a prominent strategy for handling the multiple testing problem, and has been proven to keep the required sample sizes in animal studies comparatively low. Therefore, it is a suitable approach to a compromise between the Three Rs principle of reduction and the appropriate handling of the multiplicity issue in animal trials with a confirmative focus.

RESUMEN

PURPOSE: Some patients with long postoperative intervals of undetectable prostate specific antigen are still at risk for biochemical recurrence. Our aims were to identify prognostic factors for late biochemical recurrence, including cancer family history, and evaluate cancer specific mortality. MATERIALS AND METHODS: We identified 10,310 patients after radical prostatectomy without neoadjuvant or adjuvant therapy between 1979 and 2015 in the prospective German Familial Prostate Cancer database. A subgroup of 2,480 patients with more than 10 years of followup (median 12.8) had undetectable prostate specific antigen. Biochemical recurrence, defined as prostate specific antigen 0.2 ng/ml or greater, developing at more than 10 years was defined as late biochemical recurrence. Multiple proportional hazards regression with forward selection was applied to determine prognostic factors for late biochemical recurrence. RESULTS: The Kaplan-Meier estimated biochemical recurrence rate at 10, 15 and 20 years was 34.3%, 44.0% and 52.7%, respectively. Of 2,480 patients with undetectable prostate specific antigen 10 years postoperatively 249 subsequently had biochemical recurrence, of whom 12 died of prostate cancer. The factors associated with late biochemical recurrence were age at surgery (HR 1.04 per year, p = 0.027), prostate specific antigen at diagnosis (HR 1.02 per ng/ml, p = 0.020), pathological Gleason score (categorical 2-6 vs 7 [3 + 4], 7, 7 [4 + 3] and 8-10, p = 0.002) and pathological tumor stage pT3a or greater (HR 1.50, p = 0.065). CONCLUSIONS: From years 10 to 15 and 10 to 20 postoperatively the biochemical recurrence rate increased by 9.7% and 18.4%, respectively. In contrast to a family history of prostate cancer, age at surgery, prostate specific antigen at diagnosis, pathological tumor stage and pathological Gleason score were prognostic factors for late biochemical recurrence. Patients with late biochemical recurrence are still at risk for death from prostate cancer.

RESUMEN

BACKGROUND: Patients with noninfectious uveitis are at risk for long-term complications of uncontrolled inflammation, as well as for the adverse effects of long-term glucocorticoid therapy. We conducted a trial to assess the efficacy and safety of adalimumab as a glucocorticoid-sparing agent for the treatment of noninfectious uveitis. METHODS: This multinational phase 3 trial involved adults who had active noninfectious intermediate uveitis, posterior uveitis, or panuveitis despite having received prednisone treatment for 2 or more weeks. Investigators and patients were unaware of the study-group assignments. Patients were randomly assigned in a 1:1 ratio to receive adalimumab (a loading dose of 80 mg followed by a dose of 40 mg every 2 weeks) or matched placebo. All patients received a mandatory prednisone burst followed by tapering of prednisone over the course of 15 weeks. The primary efficacy end point was the time to treatment failure occurring at or after week 6. Treatment failure was a multicomponent outcome that was based on assessment of new inflammatory lesions, best corrected visual acuity, anterior chamber cell grade, and vitreous haze grade. Nine ranked secondary efficacy end points were assessed, and adverse events were reported. RESULTS: The median time to treatment failure was 24 weeks in the adalimumab group and 13 weeks in the placebo group. Among the 217 patients in the intention-to-treat population, those receiving adalimumab were less likely than those in the placebo group to have treatment failure (hazard ratio, 0.50; 95% confidence interval, 0.36 to 0.70; P<0.001). Outcomes with regard to three secondary end points (change in anterior chamber cell grade, change in vitreous haze grade, and change in best corrected visual acuity) were significantly better in the adalimumab group than in the placebo group. Adverse events and serious adverse events were reported more frequently among patients who received adalimumab (1052.4 vs. 971.7 adverse events and 28.8 vs. 13.6 serious adverse events per 100 person-years). CONCLUSIONS: In our trial, adalimumab was found to be associated with a lower risk of uveitic flare or visual impairment and with more adverse events and serious adverse events than was placebo.
