Sexual Satisfaction Results With the Vaginal pH Modulator From the Phase 3 AMPOWER Study.

BACKGROUND: The novel vaginal pH modulator (VPM; Phexxi) is a non-hormonal, woman-controlled, on-demand, water-based, surfactant-free contraceptive vaginal gel; VPM has also been cleared by the Food and Drug Administration for use as a personal lubricant. AIM: The aim of this study is to report on sexual satisfaction results from the phase 3 AMPOWER study. METHODS: AMPOWER was a single-arm, open-label, multicenter study to assess the safety and efficacy of VPM in preventing pregnancy. Women were enrolled who were healthy, age 18-35 years, and sexually active with regular cyclic menses. OUTCOMES: Women's satisfaction (including sexual satisfaction) was an exploratory endpoint measured at Baseline and Visits 3-5; sexual satisfaction-related patient reported outcomes (PROs) were assessed via 3 different questions: (i) a question related to the impact on a woman's sex life; (ii) a question from the Sexual Function Questionnaire (SFQ) related to the frequency of ten sexual problems; and (iii) a question from the Female Sexual Function Index (FSFI) related to lubrication. RESULTS: For sexual satisfaction-related PRO measures with baseline assessments, the majority of women reported the same or improved scores at Visit 5 (ranging from 85.8% to 98.4%). The percentage of women who reported that their sex life was improved and/or maintained was higher in Visit 3, 4, and 5 (95.4%, 95.1%, and 93.6%, respectively) compared to Baseline (87.6%). The mean impact on sex life score significantly improved at Visit 5 compared to Baseline (P < .001). In the SFQ, the mean score significantly improved (P < .005) at Visit 5 vs Baseline in 7 of the 10 variables measured (vaginal dryness, lack of sexual interest and/or desire, vaginal tightness, pain, anxiety, unable to orgasm, and vaginal bleeding or irritation). In women who reported sexual activity in the last 4 weeks, the mean FSFI score also significantly improved from Baseline to Visit 5 (P = .037). CLINICAL IMPLICATIONS: In this post-hoc analysis of the phase 3 AMPOWER study, the PRO results demonstrate a high level of sexual satisfaction with VPM. STRENGTHS AND LIMITATIONS: The primary strength of this analysis was the large study size of 1,330 women. Limitations included the non-randomized study design, the post-hoc nature of the analysis, and the fact that sexual satisfaction was an exploratory endpoint. CONCLUSION: As a non-hormonal, woman-controlled, on-demand, lubricating contraceptive gel, VPM offers women a unique set of benefits with positive impacts on their sexual health.

Patient-reported outcomes from the phase II FAST trial of zolbetuximab plus EOX compared to EOX alone as first-line treatment of patients with metastatic CLDN18.2+ gastroesophageal adenocarcinoma.

BACKGROUND: Zolbetuximab plus first-line EOX (epirubicin, oxaliplatin, capecitabine; ZOL/EOX) significantly prolonged progression-free survival and overall survival in the FAST trial vs EOX alone. We report the patient-reported outcomes (PROs) of FAST in patients with advanced gastroesophageal adenocarcinoma. METHODS: Patients were randomized to ZOL/EOX or EOX alone. Patients could receive ≤ 8 EOX cycles and remained on zolbetuximab until disease progression. PROs were collected using the EORTC QLQ-C30 and QLQ-STO22 before drug administration at day 1/cycle 1, day 1/cycle 5, end of EOX treatment, and q12w thereafter until disease progression. Time to deterioration (TTD), defined as the first meaningful worsening from baseline, in the individual QLQ-C30/QLQ-STO22 scores was analyzed. Longitudinal changes in scores from baseline were analyzed using a mixed-effects model for repeated measures (MMRM). RESULTS: The per protocol population included 143 (ZOL/EOX: 69; EOX: 74) patients. Baseline QLQ-C30 and STO22 scores were comparable between arms and denoted intermediate-to-high quality of life (QoL), intermediate-to-low global health status (GHS) and low symptom burden. Descriptive analyses showed no differences between arms until end of EOX but maintenance therapy with zolbetuximab was associated with better QoL and less symptom burden thereafter. TTD for most scores favored ZOL/EOX over EOX and reached statistical significance for GHS (p = 0.008). MMRM results support TTD findings; no statistically significant differences were observed between arms in any score except for nausea and vomiting (p = 0.0181 favoring EOX). CONCLUSIONS: ZOL/EOX allowed patients to maintain good QoL and low symptom burden for longer than EOX alone.

Patient-reported outcomes following enzalutamide or placebo in men with non-metastatic, castration-resistant prostate cancer (PROSPER): a multicentre, randomised, double-blind, phase 3 trial.

BACKGROUND: In the PROSPER trial, enzalutamide significantly improved metastasis-free survival in patients with non-metastatic, castration-resistant prostate cancer. Here, we report the results of patient-reported outcomes of this study. METHODS: In the randomised, double-blind, placebo-controlled, phase 3 PROSPER trial, done at 254 study sites worldwide, patients aged 18 years or older with non-metastatic, castration-resistant prostate cancer and a prostate-specific antigen doubling time of up to 10 months were randomly assigned (2:1) via an interactive voice web recognition system to receive oral enzalutamide (160 mg per day) or placebo. Randomisation was stratified by prostate-specific antigen doubling time and baseline use of a bone-targeting agent. The primary endpoint was metastasis-free survival, reported elsewhere. Secondary efficacy endpoints, reported here, were pain progression (assessed by the Brief Pain Inventory Short Form [BPI-SF] questionnaire) and health-related quality of life (assessed with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC QLQ-PR25], the EuroQoL 5-Dimensions 5-Levels health questionnaire visual analogue scale [EQ-5D-FL, EQ-VAS], and the Functional Assessment of Cancer Therapy-Prostate [FACT-P] questionnaires). Patients completed questionnaires at baseline, week 17, and every 16 weeks thereafter until treatment discontinuation. We used predefined questionnaire thresholds to identify clinically meaningful changes. Enrolment for PROSPER is complete and follow-up continues. This trial is registered with ClinicalTrials.gov, number NCT02003924. FINDINGS: Between Nov 26, 2013, and June 28, 2017, 1401 patients were enrolled and randomly assigned to receive enzalutamide (n=933) or placebo (n=468). Median follow-up was 18·5 months (IQR 10·7-29·2) in the enzalutamide group and 15·1 months (7·4-25·9) in the placebo group. Patient-reported outcome scores at baseline were similar between groups. Changes in least squares mean from baseline to week 97 favoured enzalutamide versus placebo for FACT-P social and family wellbeing (0·30 [95% CI -0·25 to 0·85] vs -0·64 [-1·51 to 0·24]; difference 0·94 [95% CI 0·02 to 1·85]; p=0·045) and disfavoured enzalutamide versus placebo for EORTC QLQ-PR25 hormonal treatment-related symptoms (1·55 [0·26 to 2·83) vs -1·83 [-3·86 to 0·20]; difference 3·38 [1·24 to 5·51]; p=0·0020); neither of these changes were clinically meaningful. No significant differences were observed between treatments for changes from baseline to week 97 in any other patient-reported outcome score. Time to clinically meaningful pain progression as assessed by BPI-SF pain severity was longer with enzalutamide than with placebo (median 36·83 months, [95% CI 34·69 to not reached [NR] vs NR; hazard ratio [HR] 0·75 [95% CI 0·57 to 0·97]; p=0·028); there was no significant difference for BPI-SF item 3 or pain interference. Time to clinically meaningful symptom worsening was longer with enzalutamide than with placebo for EORTC QLQ-PR25 urinary symptoms (median 36·86 months [95% CI 33·35 to NR] vs 25·86 [18·53 to 29·47]; HR 0·58 [95% CI 0·46 to 0·72]; p<0·0001) and bowel symptoms (33·15 [29·50 to NR] vs 25·89 [18·43 to 29·67]; 0·72 [0·59 to 0·89]; p=0·0018), and clinically meaningful health-related quality of life as assessed by FACT-P total score (22·11 [18·63 to 25·86] vs 18·43 [14·85-19·35]; 0·83 [0·69 to 0·99]; p=0·037), emotional wellbeing (36·73 [33·12 to 38·21] vs 29·47 [22·18 to 33·15]; 0·69 [0·55 to 0·86]; p=0·0008), and prostate cancer subscale (18·43 [14·85 to 18·66] vs 14·69 [11·07 to 16·20]; 0·79 [0·67 to 0·93]; p=0·0042), although there was no significant difference for other FACT-P scores. Time to clinically meaningful deterioration in EORTC QLQ-PR25 hormonal treatment-related symptoms was shorter with enzalutamide than with placebo (median 33·15 months [95% CI 29·60 to NR] vs 36·83 [29·47 to NR]; HR 1·29 [95% CI 1·02 to 1·63]; p=0·035). Time to deterioration of EQ-VAS was significantly longer for enzalutamide than for placebo (median 22·11 months [95% CI 18·46 to 25·66] vs 14·75 [11·07 to 18·17]; HR 0·75 [95% CI 0·63 to 0·90]; p=0·0013). INTERPRETATION: Patients with non-metastatic, castration-resistant prostate cancer receiving enzalutamide had longer metastasis-free survival than did those who received placebo, while maintaining low pain levels and prostate cancer symptom burden and high health-related quality of life. Enzalutamide showed a clinical benefit by delaying pain progression, symptom worsening, and decrease in functional status, compared with placebo. These findings suggest that enzalutamide is a treatment option that should be discussed with patients presenting with high-risk, non- metastatic, castration-resistant prostate cancer.

Scale development with small samples: a new application of longitudinal item response theory.

PURPOSE: Measurement development in hard-to-reach populations can pose methodological challenges. Item response theory (IRT) is a useful statistical tool, but often requires large samples. We describe the use of longitudinal IRT models as a pragmatic approach to instrument development when large samples are not feasible. METHODS: The statistical foundations and practical benefits of longitudinal IRT models are briefly described. Results from a simulation study are reported to demonstrate the model's ability to recover the generating measurement structure and parameters using a range of sample sizes, number of items, and number of time points. An example using early-phase clinical trial data in a rare condition demonstrates these methods in practice. RESULTS: Simulation study results demonstrate that the longitudinal IRT model's ability to recover the generating parameters rests largely on the interaction between sample size and the number of time points. Overall, the model performs well even in small samples provided a sufficient number of time points are available. The clinical trial data example demonstrates that by using conditional, longitudinal IRT models researchers can obtain stable estimates of psychometric characteristics from samples typically considered too small for rigorous psychometric modeling. CONCLUSION: Capitalizing on repeated measurements, it is possible to estimate psychometric characteristics for an assessment even when sample size is small. This allows researchers to optimize study designs and have increased confidence in subsequent comparisons using scores obtained from such models. While there are limitations and caveats to consider when using these models, longitudinal IRT modeling may be especially beneficial when developing measures for rare conditions and diseases in difficult-to-reach populations.

Development of the treatment preference in myelodysplasia questionnaire for clinicians, carers, and patients.

This study reports the development activities for the Treatment Preference Myelodysplasia Questionnaires (TPMQ) for clinicians (mTPMQ), carers (cTPMQ), and patients (pTPMQ). These tools are intended to evaluate treatment preferences for patients with myelodysplastic syndromes (MDS). This was a non-interventional, cross-sectional qualitative interview study consisting of interviews with clinicians, patients, and those caring for patients with MDS. All participants were located in Australia and data were collected from qualitative mixed-method interviews composed of concept elicitation and cognitive debriefing related to initial drafts of the questionnaires. Fifteen individuals participated in interviews (five from each group). Based on the concept elicitation portion of interviews, concepts of importance were classified and reasons for treatment preference were documented. From cognitive debriefing, the questionnaires were generally deemed to be clear and easy to understand. Participant input from both concept elicitation and cognitive debriefing portions was used to revise initial drafts of the questionnaires. The mTPMQ, cTPMQ, and pTPMQ were developed with direct input from clinicians, patients, and caregivers to assess the key concepts of interest related to the preference for the treatment of MDS and are ready to be used and evaluated further in clinical trials.

Treatment for chronic idiopathic constipation: Use and satisfaction from a nationwide survey of US participants.

BACKGROUND: Chronic idiopathic constipation (CIC) is a disorder of gut-brain interaction characterized by a variety of bowel movement-related and abdominal symptoms. A greater understanding of medication use and satisfaction with symptom control may provide insights to optimize patient care. Therefore, we explored these aspects of the disorder in adults with CIC. METHODS: This study assessed data collected from a large nationwide survey of adult participants in the United States, querying demographics, clinical characteristics, and comorbid conditions, as well as medication use, care-seeking behaviors, and satisfaction with symptom control. Participants were grouped into the CIC cohort if they met Rome IV criteria, with controls matched 1:1 according to age, sex, race, region, and Charlson Comorbidity Index score. All data were self-reported. KEY RESULTS: Two thousand five hundred and thirty-three participants with CIC were matched 1:1 to controls. In the CIC cohort, abdominal pain was the most reported symptom leading to medication use: 15.9% of respondents were receiving a prescription medication in addition to an over-the-counter medication, while 26.3% were taking neither. In addition, only one-third were satisfied with the control of their symptoms; however, satisfaction was significantly higher in respondents taking a prescription medication (p < 0.001). The proportion of reported comorbidities was significantly higher in the CIC cohort versus the control cohort, with chronic pain, anxiety, and depression among the highest (p < 0.001 for all). CONCLUSIONS AND INFERENCES: This study emphasizes the need for better communication regarding prescription medications and their benefits, with the goal of further improving CIC patients' overall symptoms.

A revised estimate of the burden of illness of gout.

BACKGROUND: Gout is a chronic, inflammatory arthritis characterized by painful and debilitating acute/episodic flares. Until recently, gout has been regarded as a minor medical problem, in part because the associated economic burden has not been appreciated. Previous literature on this subject focused on the costs associated with acute episodes of gout rather than on the long-term medical and economic implications of this chronic disorder. OBJECTIVE: Our aim was to estimate the current impact of gout in the United States with respect to disability and economic costs. METHODS: THE FOLLOWING DATA SOURCES WERE USED: published data on the incremental economic burden of gout; statistics from the US Census Bureau and the US Bureau of Labor Statistics; and recent epidemiological and clinical literature concerning the course, treatment, and outcomes of the disease. Disability is expressed as days of lost productivity. Charges for gout-related treatments were used as direct cost inputs. RESULTS: Gout affects an estimated 8 million Americans, among whom those working have an average of almost 5 more absence days annually than workers without gout. On average, the incremental annual cost of care for a gout patient is estimated at >$3000 compared with a nongouty individual. Even though comorbidities common in gout patients account for a portion of this increased economic burden, the total annual cost attributable to gout patients in the United States is likely in the tens of billions of dollars and comparable to those of other major chronic disorders, such as migraine and Parkinson's disease. CONCLUSIONS: The economic burden of gout is most readily assessable in patients whose acute arthritic flares result in emergency department visits, bedridden days, and episodic loss of productivity. Chronic progression of the disease can also result in long-term impairment of function and health-related quality of life, but the contribution of chronic gout to the economic burden is more difficult to quantitate because gout is frequently associated with serious cardiovascular, metabolic, and renal comorbidities. Recent demonstration that successful gout management can reverse functional deficits in many chronic gout patients, however, supports the views that chronic gout contributes substantially to the medical and thus economic costs of these patients and that early and aggressive efforts to improve gout outcomes are likely to reduce the associated economic burden.

Think Before You Ink: Perception, Prevalence, and Correlates of Tattooing and Tattoo Regret in US Adults.

Introduction Few population-based studies have examined the perception and prevalence of tattoos and tattoo regret in the general United States (US) adult population. Our objective was to report the perception of people with tattoos and describe the prevalence, socio-demographics, health-related quality of life, and the extent of tattoo regret in US adults. Methods Data were assessed from a cross-sectional study of US adults. Participants were recruited using a random stratified sampling framework similar to the US Census. Data collected for all participants included socio-demographic and clinical characteristics, general health-related quality of life (Veterans RAND 12-item), depression (Patient Health Questionnaire 9-item), anxiety (Generalized Anxiety Disorder 7-item), and perceptions of those with tattoos. Those with tattoos also answered questions about their tattoo(s), including age when first tattooed, reasons for getting a tattoo, and tattoo regret. Categorical data were described by percentages, and continuous data by mean and standard deviation. Proportions were compared with Chi-squared tests and the means with ANOVA. A logistic regression controlling for confounding variables was carried out to assess factors predictive of tattoo regret. Results Of the 3033 participants, 35.3% (1,072) reported having a tattoo. Those more likely to have a tattoo were female (58% vs. 45%), younger (38 vs. 46 years), smoked cigarettes (38% vs. 19% non-smoker), and/or reported an alcohol or drug problem (10% vs. 5%). Those without tattoos were more likely to perceive those with tattoos as less attractive, intelligent, professional, and more rebellious. More time (in years) with a tattoo, having a tattoo on the face, neck, hands, wrist, or fingers, getting a tattoo because of peer pressure, being impaired when getting a tattoo, and experiencing an adverse event related to a tattoo were predictive of tattoo regret. Older age and remembrance as the reason for a tattoo were predictive of not having tattoo regret. Conclusion More than one-third of the study sample comprised of adults in the US reported having at least one tattoo. While most people, regardless of their tattoo status, perceived tattooed and non-tattooed individuals equally, tattooed individuals were more likely to be perceived negatively than positively by those without tattoos. Whether tattooed or not, being aware of varying perceptions of tattoo status may be helpful in facilitating positive outcomes.

US Population Reference Values for Health-Related Quality of Life Questionnaires Based on Demographics of Patients with Prostate Cancer.

INTRODUCTION: The patient experience with prostate cancer differs throughout the disease continuum, with health-related quality of life (HRQoL) and symptoms worsening as the disease progresses. To understand the prostate cancer experience, it is important to understand the experience of same-aged men without prostate cancer as a basis for comparison. This study provides the US population reference values for six patient-reported outcome (PRO) questionnaires. METHODS: A cross-sectional online survey, including several PRO questionnaires, was administered in 2019 to a representative sample of US adults. The male sample (N = 876) was raked by age to have similar characteristics of men in key advanced prostate cancer trials (mean/median age: 67.5/70.0 years), with the majority being white and non-Hispanic. RESULTS: Results from six PRO questionnaires (Brief Pain Inventory; Quality of Life in Neurological Disorders 2.0 Cognitive Short Form; PRO Measurement Information System Fatigue-Short Form; Functional Assessment of Cancer Therapy-General; European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30; and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Prostate Cancer Module) indicated that the US representative sample of men have good role, physical, and emotional functioning but slightly impaired social, functional, and overall well-being. In addition, they have normal cognitive function, few financial problems, minimal pain and fatigue, minimal urinary and bowel symptoms, and limited use of incontinence aids. CONCLUSIONS: The availability of the reference values for these PRO questionnaires will enable researchers to compare the HRQoL of patients with advanced prostate cancer in the US with that of the general US population and allow for a better interpretation of those scores. Registration numbers of advanced prostate cancer trials: NCT02677896, NCT02003924, NCT01212991, NCT00974311.

COVID-19 vaccination and race - A nationwide survey of vaccination status, intentions, and trust in the US general population.

BACKGROUND: COVID-19 vaccine hesitancy for adults and children varies depending on societal factors, race, and trust ascribed to the source of vaccine information. OBJECTIVE: To assess COVID-19 vaccination rates and trust levels for vaccine information by race at 2 time points. METHODS: Online cross-sectional data from US adults were collected in February/March 2021 (T1) and November 2021 (T2). Questions included vaccination status, reasons for vaccine refusal, trust levels for vaccine information and the Wake Forest Physician Trust Scale. At T2, parents were asked about vaccination status of children aged 12-18 years and intent for children aged 5-11 years. Vaccination rates and trust levels for vaccine information were measured. Multivariable logistic regression was used to identify characteristics predictive of receiving COVID-19 vaccination. RESULTS: Vaccination rates were 20.2% and 70.8% at T1 and T2, respectively. At T1 and T2, higher proportions of White (23.2% and 72.0%) and Other race (14.4% and 75.2%) respondents were vaccinated relative to Black respondents (9.6% and 64.4%) (P < 0.05). In descending order, respondents' doctors, family members, and pharmacists were the most trusted information sources. Black parents, relative to White and Other parents with unvaccinated children aged 12-18 years or who were not very likely to vaccinate younger children, reported lowest physician trust (P < 0.01). At T1, being married, college educated, and older and having greater Wake Forest Physician Trust Scale scores and a higher number of comorbidities predicted a higher likelihood of being vaccinated. Being Black, having a median household income less than $100,000, and residing in the Northeast or Midwest, relative to the West, predicted a decreased likelihood of being vaccinated. At T2, race and comorbidities were no longer predictive of vaccination. CONCLUSIONS: Racial variation in vaccination status decreased from T1 to T2. Physician trust predicted vaccination status and intent regardless of race. Respondents' doctors, family members, and pharmacists are trusted sources of vaccine information, and targeting these influencers may reduce vaccination hesitancy.

Using Artificial Intelligence-based Methods to Address the Placebo Response in Clinical Trials.

The placebo response is a highly complex psychosocial-biological phenomenon that has challenged drug development for decades, particularly in neurological and psychiatric disease. While decades of research have aimed to understand clinical trial factors that contribute to the placebo response, a comprehensive solution to manage the placebo response in drug development has yet to emerge. Advanced data analytic techniques, such as artificial intelligence (AI), might be needed to take the next leap forward in mitigating the negative consequences of high placebo-response rates. The objective of this review was to explore the use of techniques such as AI and the sub-discipline of machine learning (ML) to address placebo response in practical ways that can positively impact drug development. This examination focused on the critical factors that should be considered in applying AI and ML to the placebo response issue, examples of how these techniques can be used, and the regulatory considerations for integrating these approaches into clinical trials.

Psychedelic Mushrooms in the USA: Knowledge, Patterns of Use, and Association With Health Outcomes.

Introduction: Popular media coverage of psychedelics use, growing research into this class of compounds for psychiatry and decriminalization initiatives, are transforming the public perception of psychedelics. However, little is known about levels of knowledge and psychedelic mushroom (PM) use among American adults. Methods: We examined PM use and various measures of health status, quality of life, and self-reported mental health outcome measures obtained through a national on-line, cross-sectional survey of adults with a demographic composition representative of the US adult population by region, gender, age, and race (weighted N = 251,297,495) from November 2020-March 2021. Results: General mental health and well-being were popular reasons for PM use (63.6%), although use for medically-diagnosed (31.8%) and self-diagnosed (19.0%) conditions was also common. PM users reported more depression and anxiety as reflected in higher GAD-7 and PHQ-9 scores. Factors predictive of PM use included being male [OR 1.54 95%CI 1.09-2.15] and having higher Charlson Comorbidity Index scores [OR 1.42; 95%CI 1.22-1.65]. Self-reported PM use was less likely among participants with health insurance [OR = 0.50 (0.35-0.72)], increased age [OR = 0.92 (0.90-0.93)] and, relative to those living in the west US census region, living in the northeast [OR = 0.27 (0.15-0.50)], midwest [OR = 0.34 (0.20-0.56)], and south [OR = 0.38 (0.26-0.55)]. Discussion and Conclusions: A significant number of Americans are already "self-medicating" with PM and as growing positive media coverage of psychedelics drives public interest in the health benefits of PM, this number will increase. The association between PM use and poor mental health requires further research to inform policy.

COVID-19 prevalence and predictors in United States adults during peak stay-at-home orders.

BACKGROUND: Early recognition of COVID-19 cases is essential for effective public health measures aimed at isolation of individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). The objective of this study was to describe characteristics, self-reported symptoms, and predictors of testing positive for SARS-CoV-2 infection in a community-based sample. METHODS AND FINDINGS: This was a cross-sectional nationwide survey of adults in the US conducted between April 24 through May 13, 2020. The survey targeted a representative sample of approximately 5,000 respondents. The rate of COVID-19 cases and testing, most frequently reported symptoms, symptom severity, treatment received, impact of COVID-19 on mental and physical health, and factors predictive of testing positive were assessed. Most of the 5,203 participants (85.6%) reported no COVID-19-like symptoms. Of the 747 (14.5%) participants reporting COVID-19-like symptoms, 367 (49.1%) obtained a diagnostic test. Eighty-nine participants (24.3%) reported a positive COVID-19 test result, representing 1.7% of the total sample. For those testing positive, the most common symptoms were dry cough, fever, and shortness of breath/difficulty breathing. Those who tested positive were more likely to report greater symptom severity versus those who tested negative. Severe dry cough, new loss of taste or smell, trouble waking up, living with someone experiencing symptoms, recent international travel, respiratory issues, and reporting ethnicity of Black or African American were predictive of testing positive. CONCLUSIONS: This study assessed the impact of COVID-19 using community-level self-reported data across the US during the peak of most stay at home' orders. Self-reported symptoms and risk factors identified in this study are consistent with the clinical profile emerging for COVID-19. In the absence of widespread testing, this study demonstrates the utility of a representative US community-based sample to provide direct-reported symptoms and outcomes to quickly identify high-risk individuals who are likely to test positive and should consider taking greater precautions.

Psychometric evaluation of a visual analog scale for the assessment of anxiety.

BACKGROUND: Fast-acting medications for the management of anxiety are important to patients and society. Measuring early onset, however, requires a sensitive and clinically responsive tool. This study evaluates the psychometric properties of a patient-reported Global Anxiety-Visual Analog Scale (GA-VAS). METHODS: Data from a double-blind, randomized, placebo-controlled study of lorazepam and paroxetine in patients with Generalized Anxiety Disorder were analyzed to assess the reliability, validity, responsiveness, and utility of the GA-VAS. The GA-VAS was completed at clinic visits and at home during the first week of treatment. Targeted psychometric analyses--test-retest reliabilities, validity correlations, responsiveness statistics, and minimum important differences--were conducted. RESULTS: The GA-VAS correlates well with other anxiety measures, at Week 4, r=0.60 (p<0.0001) with the Hamilton Rating Scale for Anxiety and r=0.74 (p<0.0001) with the Hospital Anxiety and Depression Scale-Anxiety subscale. In terms of convergent and divergent validity, the GA-VAS correlated -0.54 (p<0.0001), -0.48 (p<0.0001), and -0.68 (p<0.0001) with the SF-36 Emotional Role, Social Function, and Mental Health subscales, respectively, but correlated much lower with the SF-36 physical functioning subscales. Preliminary minimum important difference estimates cluster between 10 and 15 mm. CONCLUSIONS: The GA-VAS is capable of validly and effectively capturing a reduction in anxiety as quickly as 24 hours post-dose.

Effect of Enzalutamide plus Androgen Deprivation Therapy on Health-related Quality of Life in Patients with Metastatic Hormone-sensitive Prostate Cancer: An Analysis of the ARCHES Randomised, Placebo-controlled, Phase 3 Study.

BACKGROUND: In the ARCHES study in metastatic hormone-sensitive prostate cancer (mHSPC), enzalutamide plus androgen deprivation therapy (ADT) improved radiographic progression-free survival (rPFS) versus ADT alone. OBJECTIVE: To evaluate patient-reported outcomes (PROs) to week 73. DESIGN, SETTING, AND PARTICIPANTS: ARCHES (NCT02677896) was a randomised, double-blind, placebo-controlled, phase 3 study in mHSPC patients. INTERVENTION: Enzalutamide (160 mg/day) plus ADT or placebo plus ADT. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: PROs were assessed at baseline, week 13, and every 12 wk until disease progression using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Prostate 25 (QLQ-PR25), Functional Assessment of Cancer Therapy-Prostate (FACT-P), Brief Pain Inventory Short Form, and EuroQoL 5-Dimensions, 5-Levels (EQ-5D-5 L) instruments. Endpoints included time to first (TTFD) and first confirmed (TTFCD) clinically meaningful deterioration (using predefined questionnaire thresholds) in health-related quality of life (HRQoL) and pain. RESULTS AND LIMITATIONS: A total of 1150 patients received ADT plus enzalutamide (n = 574) or placebo (n = 576). Baseline PRO scores indicated high HRQoL and low pain, which was generally maintained in both groups. There were no statistically significant (nominal p > 0.05) between-group differences that occurred in both TTFD and TTFCD together for QLQ-PR25 and FACT-P scores. Enzalutamide significantly delayed TTFD in worst pain (by ∼3 mo; nominal p = 0.032), pain severity (nominal p = 0.021), and EQ-5D-5 L visual analogue scale score (nominal p = 0.0070) versus placebo (not significant for confirmed deterioration for pain outcomes). Enzalutamide delays deterioration in several HRQoL subscales and pain severity in high-volume disease. CONCLUSIONS: Enzalutamide plus ADT enables men with mHSPC to maintain high-functioning HRQoL and low symptom burden. PATIENT SUMMARY: This study examined the effect on health-related quality of life and pain of adding enzalutamide or placebo to androgen deprivation therapy for patients with metastatic hormone-sensitive prostate cancer. Addition of enzalutamide allowed patients to maintain their health-related quality of life.

Association between changes on the Negative Symptom Assessment scale (NSA-16) and measures of functional outcome in schizophrenia.

We examined whether changes in negative symptoms, as measured by scores on the 16-item Negative Symptom Assessment scale (NSA-16), were associated with changes in functional outcome. A group of 125 stable outpatients with schizophrenia were assessed at baseline and at 6 months using the NSA-16, the Brief Psychiatric Rating Scale, and multiple measures of functional outcome. Baseline adjusted regression coefficients indicated moderate correlations between negative symptoms and functional outcomes when baseline values of both variables were controlled. Results were nearly identical when we controlled for positive symptoms. Cross-lag panel correlations and Structural Equation Modeling were used to examine whether changes in negative symptoms drove changes in functional outcomes over time. Results indicated that negative symptoms drove the changes in the Social and Occupational Functioning Scale (SOFAS) rather than the reverse. Measures of Quality of Life and measures of negative symptoms may be assessing overlapping constructs or changes in both may be driven by a third variable. Negative symptoms were unrelated over time to scores on a performance-based measure of functional capacity. This study indicates that the relationship between negative symptom change and the change in functional outcomes is complex, and points to potential issues in selection of assessments.

Symptoms and Impacts in Metastatic Castration-Resistant Prostate Cancer: Qualitative Findings from Patient and Physician Interviews.

BACKGROUND: There is little information available on health-related quality of life in patients with chemotherapy-naïve metastatic castration-resistant prostate cancer. This study aimed to develop a conceptual model that describes patients' experiences of living with this condition. METHODS: This was a cross-sectional, non-interventional qualitative research study. Sixty-minute semi-structured interviews were conducted with physicians experienced in treating metastatic castration-resistant prostate cancer and with chemotherapy-naïve patients with metastatic castration-resistant prostate cancer. Interviews were audio-recorded and transcripts were analysed to identify the key symptoms and impacts on quality of life. Results were used to expand a previously published conceptual model for non-metastatic castration-resistant prostate cancer. RESULTS: Three physicians and 19 patients with metastatic castration-resistant prostate cancer were interviewed. Physicians identified several symptoms frequently mentioned by their patients: fatigue, bone pain, anxiety, stress, depression and interference with daily activities. The most salient symptoms emerging from the patient interviews were urinary frequency and urgency, fatigue, pain/stiffness and sexual dysfunction. The most salient impacts were interference with daily activities, frustration, anxiety and sleep problems. Compared with non-metastatic castration-resistant prostate cancer, some symptoms and impacts in metastatic castration-resistant prostate cancer were more common and rated as more disturbing (e.g. fatigue, pain, urinary frequency, interference with daily activities and frustration). New concepts that were added to the non-metastatic castration-resistant prostate cancer model, to more accurately reflect the experiences of patients with metastatic disease, were enlarged breasts, muscle loss/deconditioning, inability to focus/mental slowing, body image perception, interference with work and lack of ambition/motivation. CONCLUSIONS: Chemotherapy-naïve patients with metastatic castration-resistant prostate cancer experience a substantial burden from their condition. Furthermore, as castration-resistant prostate cancer progresses from the non-metastatic stage to the early metastatic (pre-chemotherapy) stage, certain symptoms become more common and disturb patients' lives to a greater extent. The resulting conceptual model for metastatic castration-resistant prostate cancer highlights areas that are not adequately assessed with current patient-reported outcome instruments.

The economic burden of uncontrolled gout: how controlling gout reduces cost.

AIM: To evaluate the burden of uncontrolled gout by examining estimated costs and cost drivers. MATERIALS AND METHODS: Data from the 2012 and 2013 US National Health and Wellness Survey (NHWS; 2012 NHWS, n = 71,157 and 2013 NHWS, n = 75,000) were utilized in this study. Based on self-reported gout diagnosis and gout symptoms, respondents were categorized into three groups: controlled gout (n = 344), uncontrolled gout (n = 2,215), and non-gout controls (n = 126,360). Chi-square tests and one-way analysis of variance (ANOVAs) were used to assess group differences on work productivity loss, healthcare resource utilization, and costs. Zero-inflated negative binomial regressions were used to assess the burden of uncontrolled gout on total costs after controlling for covariates. RESULTS: Patients with uncontrolled gout had higher presenteeism, overall work impairment, activity impairment, and number of emergency department visits than those with controlled gout or controls. Overall, uncontrolled gout patients had both higher indirect and total costs compared to patients with controlled gout. After controlling for confounders, those with uncontrolled gout had higher total costs than controlled gout respondents and non-gout controls; there was no significant difference in total costs between patients with controlled gout and non-gout controls. LIMITATIONS: Results were based on cross-sectional, self-reported data, making causal inferences more uncertain. Additionally, sample size was small for controlled-gout respondents. Lastly, sampling weights were not used, thus potentially limiting generalizability. CONCLUSION: Gout can be an expensive condition, particularly if it is not properly controlled. This study provides support that controlling symptoms (e.g. flares) can reduce the economic and societal burden of gout. Therefore, more attention needs to be paid to effective management of gout symptoms.

Gout and the risk of advanced chronic kidney disease in the UK health system: a national cohort study.

OBJECTIVE: Evaluate the association between gout and risk of advanced chronic kidney disease (CKD). DESIGN: Retrospective matched cohort study. SETTING: UK Clinical Practice Research Datalink. PARTICIPANTS: The analysis included data for 68 897 patients with gout and 554 964 matched patients without gout. Patients were aged ≥18 years, registered at UK practices, had ≥12 months of clinical data and had data linked with Hospital Episode Statistics. Patients were excluded for history of advanced CKD, juvenile gout, cancer, HIV, tumour lysis syndrome, Lesch-Nyhan syndrome or familial Mediterranean fever. PRIMARY AND SECONDARY OUTCOME MEASURES: Advanced CKD was defined as first occurrence of: (1) dialysis, kidney transplant, diagnosis of end-stage kidney disease (ESKD) or stage 5 CKD (diagnostic codes in Read system or International Classification of Diseases, Tenth Revision); (2) estimated glomerular filtration rate (eGFR) <10 mL/min/1.73 m²; (3) doubling of serum creatinine from baseline and (4) death associated with CKD. RESULTS: Advanced CKD incidence was higher for patients with gout (8.54 per 1000 patient-years; 95% CI 8.26 to 8.83) versus without gout (4.08; 95% CI 4.00 to 4.16). Gout was associated with higher advanced CKD risk in both unadjusted analysis (HR, 2.00; 95% CI 1.92 to 2.07) and after adjustment (HR, 1.29; 95% CI 1.23 to 1.35). Association was strongest for ESKD (HR, 2.13; 95% CI 1.73 to 2.61) and was present for eGFR <10 mL/min/1.73 m² (HR, 1.45; 95% CI 1.30 to 1.61) and serum creatinine doubling (HR, 1.13; 95% CI 1.08 to 1.19) but not CKD-associated death (HR, 1.14; 95% CI 0.99 to 1.31). Association of gout with advanced CKD was replicated in propensity-score matched analysis (HR, 1.23; 95% CI 1.17 to 1.29) and analysis limited to patients with incident gout (HR, 1.28; 95% CI 1.22 to 1.35). CONCLUSIONS: Gout is associated with elevated risk of CKD progression. Future studies should investigate whether controlling gout is protective and reduces CKD risk.
