Collagenase Injection versus Limited Fasciectomy for Dupuytren's Contracture.

BACKGROUND: Treatments for Dupuytren's contracture include limited fasciectomy and collagenase injection. Comparisons of the effectiveness of these treatments have been limited. METHODS: We performed an unblinded, multicenter, pragmatic, two-group, randomized, controlled noninferiority trial comparing collagenase injection with limited fasciectomy in persons with moderate Dupuytren's contracture. The primary outcome was the score on the Patient Evaluation Measure-Hand Health Profile (PEM), a questionnaire for assessing hand health as reported by the patient, at 1 year after treatment. Scores on the PEM range from 0 to 100, with higher scores indicating worse outcomes. The prespecified noninferiority margin was 6 points. RESULTS: A total of 672 persons (336 per group) were assigned to receive collagenase injection or to undergo limited fasciectomy. The primary analysis included 599 persons: 314 in the collagenase group and 285 in the limited-fasciectomy group. The mean score on the PEM at 1 year was 17.8 among the 284 patients with available data in the collagenase group and 11.9 among the 250 patients with available data in the limited-fasciectomy group (estimated difference, 5.9 points; 95% confidence interval [CI], 3.1 to 8.8; one-sided P = 0.49 for noninferiority). Among the patients with available data (229 patients in the collagenase group and 197 patients in the limited-fasciectomy group), the estimated difference in the mean score on the PEM at 2 years was 7.2 points (95% CI, 4.2 to 10.9). Moderate or severe complications of treatment occurred in 1.8% of the patients in the collagenase group and in 5.1% of those in the limited-fasciectomy group; recurrent contracture resulted in reintervention in 14.6% and 3.4%, respectively. CONCLUSIONS: Collagenase injection was not noninferior to limited fasciectomy with respect to the score on the PEM at 1 year after treatment.

Pain Reduction With Oral Methotrexate in Knee Osteoarthritis : A Randomized, Placebo-Controlled Clinical Trial.

BACKGROUND: Treatments for osteoarthritis (OA) are limited. Previous small studies suggest that the antirheumatic drug methotrexate may be a potential treatment for OA pain. OBJECTIVE: To assess symptomatic benefits of methotrexate in knee OA (KOA). DESIGN: A multicenter, randomized, double-blind, placebo-controlled trial done between 13 June 2014 and 13 October 2017. (ISRCTN77854383; EudraCT: 2013-001689-41). SETTING: 15 secondary care musculoskeletal clinics in the United Kingdom. PARTICIPANTS: A total of 207 participants with symptomatic, radiographic KOA and knee pain (severity ≥4 out of 10) on most days in the past 3 months with inadequate response to current medication were approached for inclusion. INTERVENTION: Participants were randomly assigned 1:1 to oral methotrexate once weekly (6-week escalation 10 to 25 mg) or matched placebo over 12 months and continued usual analgesia. MEASUREMENTS: The primary end point was average knee pain (numerical rating scale [NRS] 0 to 10) at 6 months, with 12-month follow-up to assess longer-term response. Secondary end points included knee stiffness and function outcomes and adverse events (AEs). RESULTS: A total of 155 participants (64% women; mean age, 60.9 years; 50% Kellgren-Lawrence grade 3 to 4) were randomly assigned to methotrexate (n = 77) or placebo (n = 78). Follow-up was 86% (n = 134; methotrexate: 66, placebo: 68) at 6 months. Mean knee pain decreased from 6.4 (SD, 1.80) at baseline to 5.1 (SD, 2.32) at 6 months in the methotrexate group and from 6.8 (SD, 1.62) to 6.2 (SD, 2.30) in the placebo group. The primary intention-to-treat analysis showed a statistically significant pain reduction of 0.79 NRS points in favor of methotrexate (95% CI, 0.08 to 1.51; P = 0.030). There were also statistically significant treatment group differences in favor of methotrexate at 6 months for Western Ontario and McMaster Universities Osteoarthritis Index stiffness (0.60 points [CI, 0.01 to 1.18]; P = 0.045) and function (5.01 points [CI, 1.29 to 8.74]; P = 0.008). Treatment adherence analysis supported a dose-response effect. Four unrelated serious AEs were reported (methotrexate: 2, placebo: 2). LIMITATION: Not permitting oral methotrexate to be changed to subcutaneous delivery for intolerance. CONCLUSION: Oral methotrexate added to usual medications demonstrated statistically significant reduction in KOA pain, stiffness, and function at 6 months. PRIMARY FUNDING SOURCE: Versus Arthritis.

Diagnosis and management of selective fetal growth restriction in monochorionic twin pregnancies: A cross-sectional international survey.

OBJECTIVE: To identify current practices in the management of selective fetal growth restriction (sFGR) in monochorionic diamniotic (MCDA) twin pregnancies. DESIGN: Cross-sectional survey. SETTING: International. POPULATION: Clinicians involved in the management of MCDA twin pregnancies with sFGR. METHODS: A structured, self-administered survey. MAIN OUTCOME MEASURES: Clinical practices and attitudes to diagnostic criteria and management strategies. RESULTS: Overall, 62.8% (113/180) of clinicians completed the survey; of which, 66.4% (75/113) of the respondents reported that they would use an estimated fetal weight (EFW) of <10th centile for the smaller twin and an inter-twin EFW discordance of >25% for the diagnosis of sFGR. For early-onset type I sFGR, 79.8% (75/94) of respondents expressed that expectant management would be their routine practice. On the other hand, for early-onset type II and type III sFGR, 19.3% (17/88) and 35.7% (30/84) of respondents would manage these pregnancies expectantly, whereas 71.6% (63/88) and 57.1% (48/84) would refer these pregnancies to a fetal intervention centre or would offer fetal intervention for type II and type III cases, respectively. Moreover, 39.0% (16/41) of the respondents would consider fetoscopic laser surgery (FLS) for early-onset type I sFGR, whereas 41.5% (17/41) would offer either FLS or selective feticide, and 12.2% (5/41) would exclusively offer selective feticide. For early-onset type II and type III sFGR cases, 25.9% (21/81) and 31.4% (22/70) would exclusively offer FLS, respectively, whereas 33.3% (27/81) and 32.9% (23/70) would exclusively offer selective feticide. CONCLUSIONS: There is significant variation in clinician practices and attitudes towards the management of early-onset sFGR in MCDA twin pregnancies, especially for type II and type III cases, highlighting the need for high-level evidence to guide management.

Epidemiology of Early Monkeypox Virus Transmission in Sexual Networks of Gay and Bisexual Men, England, 2022.

After community transmission of monkeypox virus was identified in Europe, interviews of 45 case-patients from England indicated transmission in international sexual networks of gay and bisexual men since April 2022. Interventions targeting sex-on-premises venues, geospatial dating applications, and sexual health services are likely to be critical for outbreak control.

A pilot cluster randomised trial of the medicines and alcohol consultation (MAC): an intervention to discuss alcohol use in community pharmacy medicine review services.

BACKGROUND: Alcohol interventions are important to the developing public health role of community pharmacies. The Medicines and Alcohol Consultation (MAC) is a new intervention, co-produced with community pharmacists (CPs) and patients, which involves a CP practice development programme designed to integrate discussion of alcohol within existing NHS medicine review services. We conducted a pilot trial of the MAC and its delivery to investigate all study procedures to inform progression to a definitive trial. METHODS: This cluster pilot RCT was conducted in 10 community pharmacies in Yorkshire, UK, with a CP from each who regularly conducted Medicine Use Review (MUR) and New Medicine Service (NMS) consultations. Randomisation was conducted using a secure remote randomisation service. Intervention CPs (n = 5) were trained to deliver the MAC in MUR/NMS consultations. Control CPs (n = 5) provided these services as usual. Consecutive MUR/NMS patients were asked by CPs to participate, screened for eligibility (consumption of alcohol at least twice per week), and baseline data collected for those eligible. A two-month follow-up telephone interview was conducted. Blinding of CPs was not possible, but patients were blinded to the alcohol focus of the trial. Primary outcomes were total weekly UK units (8 g of ethanol per unit) of alcohol consumption in the week prior to follow-up, and confidence in medications management. Trial procedures were assessed by recruitment, attrition, and follow-up rates. RESULTS: 260 patients were approached by CPs to take part in the trial, 68% (n = 178) were assessed for eligibility and 30% (n = 54) of these patients were eligible. Almost all eligible patients (n = 51; 94%) consented to participate, of whom 92% (n = 47) were followed-up at 2 months; alcohol consumption was lower in the intervention arm and confidence in medication management reduced slightly for both groups. Exploration of recall issues at follow-up showed a high level of agreement between a two-item quantity/frequency measure and 7-day guided recall of alcohol consumption. CONCLUSIONS: The pilot trial demonstrates the feasibility of implementing the MAC in community pharmacy and trial recruitment and data collection procedures. However, decommissioning of MURs means that it is not possible to conduct a definitive trial of the intervention in this service. TRIAL REGISTRATION: ISRCTN57447996.

The formation of endoderm-derived taste sensory organs requires a Pax9-dependent expansion of embryonic taste bud progenitor cells.

In mammals, taste buds develop in different regions of the oral cavity. Small epithelial protrusions form fungiform papillae on the ectoderm-derived dorsum of the tongue and contain one or few taste buds, while taste buds in the soft palate develop without distinct papilla structures. In contrast, the endoderm-derived circumvallate and foliate papillae located at the back of the tongue contain a large number of taste buds. These taste buds cluster in deep epithelial trenches, which are generated by intercalating a period of epithelial growth between initial placode formation and conversion of epithelial cells into sensory cells. How epithelial trench formation is genetically regulated during development is largely unknown. Here we show that Pax9 acts upstream of Pax1 and Sox9 in the expanding taste progenitor field of the mouse circumvallate papilla. While a reduced number of taste buds develop in a growth-retarded circumvallate papilla of Pax1 mutant mice, its development arrests completely in Pax9-deficient mice. In addition, the Pax9 mutant circumvallate papilla trenches lack expression of K8 and Prox1 in the taste bud progenitor cells, and gradually differentiate into an epidermal-like epithelium. We also demonstrate that taste placodes of the soft palate develop through a Pax9-dependent induction. Unexpectedly, Pax9 is dispensable for patterning, morphogenesis and maintenance of taste buds that develop in ectoderm-derived fungiform papillae. Collectively, our data reveal an endoderm-specific developmental program for the formation of taste buds and their associated papilla structures. In this pathway, Pax9 is essential to generate a pool of taste bud progenitors and to maintain their competence towards prosensory cell fate induction.

FERN: is it possible to conduct a randomised controlled trial of intervention or expectant management for early-onset selective fetal growth restriction in monochorionic twin pregnancy - protocol for a prospective multicentre mixed-methods feasibility study.

INTRODUCTION: Selective fetal growth restriction (sFGR) in monochorionic twin pregnancy, defined as an estimated fetal weight (EFW) of one twin <10th centile and EFW discordance ≥25%, is associated with stillbirth and neurodisability for both twins. The condition poses unique management difficulties: on the one hand, continuation of the pregnancy carries a risk of death of the smaller twin, with a high risk of co-twin demise (40%) or co-twin neurological sequelae (30%). On the other, early delivery to prevent the death of the smaller twin may expose the larger twin to prematurity, with the associated risks of long-term physical, emotional and financial costs from neurodisability, such as cerebral palsy.When there is severe and early sFGR, before viability, delivery is not an option. In this scenario, there are currently three main management options: (1) expectant management, (2) selective termination of the smaller twin and (3) placental laser photocoagulation of interconnecting vessels. These management options have never been investigated in a randomised controlled trial (RCT). The best management option is unknown, and there are many challenges for a potential RCT. These include the rarity of the condition resulting in a small number of eligible pregnancies, uncertainty about whether pregnant women will agree to participate in such a trial and whether they will agree to be randomised to expectant management or active fetal intervention, and the challenges of robust and long-term outcome measures. Therefore, the main objective of the FERN study is to assess the feasibility of conducting an RCT of active intervention vs expectant management in monochorionic twin pregnancies with early-onset (prior to 24 weeks) sFGR. METHODS AND ANALYSIS: The FERN study is a prospective mixed-methods feasibility study. The primary objective is to recommend whether an RCT of intervention vs expectant management of sFGR in monochorionic twin pregnancy is feasible by exploring women's preference, clinician's preference, current practice and equipoise and numbers of cases. To achieve this, we propose three distinct work packages (WPs). WP1: A Prospective UK Multicentre Study, WP2A: a Qualitative Study Exploring Parents' and Clinicians' Views and WP3: a Consensus Development to Determine Feasibility of a Trial. Eligible pregnancies will be recruited to WP1 and WP2, which will run concurrently. The results of these two WPs will be used in WP3 to develop consensus on a future definitive study. The duration of the study will be 53 months, composed of 10 months of setup, 39 months of recruitment, 42 months of data collection, and 5 months of data analysis, report writing and recommendations. The pragmatic sample size for WP1 is 100 monochorionic twin pregnancies with sFGR. For WP2, interviews will be conducted until data saturation and sample variance are achieved, that is, when no new major themes are being discovered. Based on previous similar pilot studies, this is anticipated to be approximately 15-25 interviews in both the parent and clinician groups. Engagement of at least 50 UK clinicians is planned for WP3. ETHICS AND DISSEMINATION: This study has received ethical approval from the Health Research Authority (HRA) South West-Cornwall and Plymouth Ethics Committee (REC reference 20/SW/0156, IRAS ID 286337). All participating sites will undergo site-specific approvals for assessment of capacity and capability by the HRA. The results of this study will be published in peer-reviewed journals and presented at national and international conferences. The results from the FERN project will be used to inform future studies. TRIAL REGISTRATION NUMBER: This study is included in the ISRCTN Registry (ISRCTN16879394) and the NIHR Central Portfolio Management System (CPMS), CRN: Reproductive Health and Childbirth Specialty (UKCRN reference 47201).

Modulation of cytokine and nitric oxide production by keratinocytes, epithelial cells, and mononuclear phagocytes in a co-culture model of inflammatory acne.

INTRODUCTION: Ultraviolet B (UVB, 290 nm to 320 nm) has been reported to modulate the cytokine-mediated inflammatory process in various inflammatory skin conditions, including production of TNF-α, IL-1α, IL-6, IL-8, and IL-10. We constructed an in vitro model system involving co-culture of different cell types to study the effect of UVB on the inflammatory process using nitric oxide (NO) and tumor necrosis factor (TNF)-α as markers of inflammation. OBJECTIVE: This study was conducted to quantitatively assess the products secreted by human epithelial keratinocytes in the presence and absence of macrophages/monocytes. METHODS: Cells were exposed to UVB radiation (50 mJ to 200 mJ per cm2) or treated with bacterial lipopolysaccharide (LPS) as stimulator of inflammatory response. Nitric oxide (NO) was measured by modified Griess assay and TNF-α was measured by quantitative ELISA. For the co-culture system, SC monocytes were seeded in a 24-well Transwell tissue culture plate whereas irradiated keratinocytes were seeded in the individual baskets subsequently placed on top of the monocyte cultures, and samples of culture supernatants were collected at 1 to 6 days. RESULTS: When primary human epidermal keratinocytes (NHEK) were irradiated with UVB, a dose-dependent stimulation of TNF-α production was observed (33% to 200% increase). TNF-α production was not changed significantly in SC monocytes/NHEK co-culture. In contrast, when macrophages were irradiated with UVB, significant inhibition of NO production (40% suppression, P<0.001) was seen. CONCLUSION: This improved model of cutaneous inflammation could use multiple cells to study their interactions and to offer convenience, reproducibility, and a closer approximation of in vivo conditions.

Self-forgiveness in anorexia nervosa and bulimia nervosa.

This study investigated whether low levels of self-forgiveness were associated with eating disorder symptomatology. Participating women (N = 51) had diagnoses of anorexia nervosa, bulimia nervosa, or no eating disorder diagnosis. They completed 3 measures of self-forgiveness. Women with eating disorders had lower levels of self-forgiveness compared with control participants. Results suggest that incorporating self-forgiveness interventions into current eating disorder treatments should be evaluated in future research as they might enhance clinical outcomes.

A Systematic Literature Review of Health-related Quality of Life Measures for Women with Hypoactive Sexual Desire Disorder and Female Sexual Interest/Arousal Disorder.

INTRODUCTION: Hypoactive Sexual Desire Disorder (HSDD) / Female Sexual Interest/Arousal Disorder (FSIAD) impacts health-related quality of life (HRQoL) of women and their partners, yet existing measures fail to adequately capture relevant concepts (ie, what is essential to measure including symptoms/impacts) important to women with HSDD/FSIAD. OBJECTIVES: To identify HRQoL tools used to assess women with HSDD/FSIAD, and to evaluate their psychometric properties (ie, reliability, validity, and responsiveness). METHODS: We conducted searches in PubMed, Embase and PsychINFO from June 5, 1989 to September 30, 2020 for studies in women with HSDD/FSIAD and psychometric analyses (English only). Principles of the Preferred Reporting Items for Systematic reviews and Meta-Analyses, the COnsensus-based Standards for the selection of health Measurement INstruments Risk of Bias Checklist and other psychometric criteria were applied. Based on this search, 56 papers were evaluated including 15 randomized-controlled trials, 11 observational/single arm/open label studies, and 30 psychometric studies. RESULTS: Of the 18 measures identified, the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R) were included in most studies (> 50%). General HRQoL instruments were not used in any of the clinical trials; the SF-12, SF-36 and EQ-5D-5L were reported in two observational studies. No instruments achieved positive quality ratings across all psychometric criteria. The FSFI, FSDS-R, Sexual Event Diary (SED) and the Sexual Desire Relationship Distress Scale (SDRDS), were the only measures to receive a positive rating for content validity. CONCLUSION: Reliable and valid HRQoL measures that include sexual desire and distress are needed to provide a more systematic and comprehensive assessment of HRQoL and treatment benefits in women with HSDD/FSIAD. While inferences about HRQoL are limited due to the lack of uniformity in concepts assessed and limited psychometric evaluation of these measures in women with HSDD/FSIAD, opportunities exist for the development of reliable and validated tools that comprehensively measure the most relevant and important concepts in women with HSDD/FSIAD.

Clinical Burden and Unmet Need in Recurrent Pericarditis: A Systematic Literature Review.

Inflammation of the pericardium (pericarditis) is characterized by excruciating chest pain. This systematic literature review summarizes clinical, humanistic, and economic burdens in acute, especially recurrent, pericarditis, with a secondary aim of understanding United States treatment patterns and outcomes. Short-term clinical burden is well characterized, but long-term data are limited. Some studies report healthcare resource utilization and economic impact; none measure health-related quality-of-life. Pericarditis is associated with infrequent but potentially life-threatening complications, including cardiac tamponade (weighted average: 12.7% across 10 studies), constrictive pericarditis (1.84%; 9 studies), and pericardial effusion (54.7%; 16 studies). There are no approved pericarditis treatments; treatment guidelines, when available, are inconsistent on treatment course or duration. Most recommend first-line use of conventional treatments, for example, nonsteroidal antiinflammatory drugs with or without colchicine; however, 15-30% of patients experience recurrence. Second-line therapy may involve conventional therapies plus long-term utilization of corticosteroids, despite safety issues and the difficulty of tapering or discontinuation. Other exploratory therapies (eg, azathioprine, immunoglobulin, methotrexate, anakinra) present steroid-sparing options, but none are supported by robust clinical evidence, and some present tolerability challenges that may impact adherence. Pericardiectomy is occasionally pursued in treatment-refractory patients, although data are limited. This lack of an evidence-based treatment pathway for patients with recurrent disease is reflected in readmission rates, for example, 12.2% at 30 days in 1 US study. Patients with continued recurrence and inadequate treatment response need approved, safe, accessible treatments to resolve pericarditis symptoms and reduce recurrence risk without excessive treatment burden.

Assessing the Burden of Illness Associated with Acquired Generalized Hypoactive Sexual Desire Disorder.

Background: Hypoactive sexual desire disorder (HSDD), which affects ∼10% of women in the United States, is defined as the persistent or recurrent deficiency/absence of sexual desire accompanied by personal distress. Although HSDD impacts patient quality of life and interpersonal relationships, the disorder often goes unaddressed or untreated. Recent studies of the burden of illness in women with HSDD, especially premenopausal women, are limited. Materials and Methods: A 45-minute web-based survey was designed to investigate the experience of women seeking treatment for HSDD and the impact of this disorder on several psychosocial aspects of women's lives. Women were recruited from an online panel of patients who participated in research studies for compensation. Validated questionnaires assessed sexual function (Female Sexual Function Index) and health-related quality of life (12-Item Short Form Survey [SF-12]), including mental and physical component scores. Results: A total of 530 women, aged ≥18 years, diagnosed with acquired generalized HSDD were included in the study. Premenopausal women indicated greater overall HSDD symptom burden compared with postmenopausal women. Patients with HSDD reported lower SF-12 scores compared with the general population. A multivariable regression analysis demonstrated that psychosocial factors influencing the burden of HSDD, including interference with their relationship with their partner (ß = -0.18; p < 0.005), mental and emotional well-being (ß = -0.23; p < 0.005), and household and personal activities (ß = -0.23; p = 0.02), negatively affected SF-12 mental component scores. Conclusions: HSDD symptom burden was found to be negatively and statistically significantly associated with patients' mental health; the impact was greater among premenopausal women compared with postmenopausal women.

The feasibility and acceptability of a brief psychological intervention for adults with long-term health conditions and subthreshold depression delivered via community pharmacies: a mixed methods evaluation-the Community Pharmacies Mood Intervention Study (CHEMIST).

BACKGROUND: Adults with long-term health conditions (LTCs) are more likely to experience depressive symptoms which can worsen health outcomes and quality of life, and increase healthcare costs. Subthreshold depression may go undetected and/or untreated. The Community Pharmacies Mood Intervention Study (CHEMIST) explored whether community pharmacies represent a suitable setting to offer brief psychological support to people with LTCs and comorbid subthreshold depression. METHODS: A feasibility intervention study with a nested mixed methods evaluation was employed. Adults with subthreshold depression and a minimum of one LTC were recruited from community pharmacies/local general practices and offered a brief psychological support intervention ('Enhanced Support Intervention' (ESI)), based on behavioural activation within a Collaborative Care framework. The intervention included up to six sessions supported by pharmacy staff ('ESI facilitators') trained to deliver the ESI within the community pharmacy setting. Recruitment, retention rates and engagement with the ESI were assessed. Semi-structured, one-to-one interviews with pharmacy staff and study participants, and a focus group with pharmacy staff, explored experiences and acceptability of the study and the ESI. Themes were mapped onto constructs of the Theoretical Framework of Acceptability. RESULTS: Recruitment of ESI participants was challenging and slower than anticipated despite the varied methods of recruitment employed; although, this was useful in identifying barriers and enabling factors for participation. Engagament with the ESI was good with n=17 (71%) recruited participants commencing the ESI. The ESI was found to be acceptable to participants and ESI facilitators. Retention rate at 4 months was good n=20 (87.0%). The main barriers to identifying potential participants for pharmacy staff were lack of time, resources and limited experience in research. The ESI training and support manual were acceptable to ESI facilitators. The ESI and supporting patient workbook were acceptable to people with LTCs and subthreshold depression. CONCLUSIONS: Community pharmacies were viewed as an acceptable setting in which to deliver preventative brief psychological support to people with LTCs at risk of depression. This feasibility study provided important data to inform the design of a pilot randomised controlled trial in this setting and highlighted important considerations for future pharmacy-based research. TRIAL REGISTRATION: ISRCTN11290592.

Estimating the US pericarditis prevalence using national health encounter surveillance databases.

OBJECTIVE: To obtain a nationally representative annualized estimate of the prevalence of pericarditis (inflammation of the pericardium) in the United States (US) in order to better understand the potential burden on the health care system. METHODS: Three nationally representative datasets were used to estimate the annualized period prevalence and prevalence rate of pericarditis from 2007 to 2016: the National Ambulatory Medical Care Survey (NAMCS), the National Hospital Ambulatory Medical Care Survey (NHAMCS), and the Nationwide Inpatient Sample (NIS). Across all data sources, ICD-9/10 codes were used to identify healthcare encounters with ≥1 primary or secondary diagnosis related to pericarditis irrespective of duration or etiology. The prevalence of pericarditis in 2020 was extrapolated by multiplying the average annualized prevalence rate from 2007 to 2016 by the total US population as of March 2020. RESULTS: Data from NAMCS/NHAMCS (2007-2016) yielded an average annualized estimate of 125,209 patients with pericarditis, resulting in a pooled average annualized prevalence estimate of 40 patients with pericarditis per 100,000 persons. Data from NIS (2007-2016) yielded an average annualized estimate of 34,441 patients with pericarditis, resulting in a pooled average annualized prevalence estimate of 11 hospitalized patients with pericarditis per 100,000 persons. Extrapolation of these results based on the March 2020 population estimates from the US Census Bureau of 329,436,928 resulted in an estimated US prevalence of pericarditis to be approximately160,000. CONCLUSION: Despite certain methodologic limitations, our analysis of data from nationally representative sources support that pericarditis is a rare disease affecting substantially fewer than 200,000 persons in the US.

Interleukin-1 Trap Rilonacept Improved Health-Related Quality of Life and Sleep in Patients With Recurrent Pericarditis: Results From the Phase 3 Clinical Trial RHAPSODY.

Background Recurrent pericarditis is characterized by painful flares and inflammation, which negatively impact health-related quality of life. RHAPSODY (rilonacept inhibition of interleukin-1 alpha and beta for recurrent pericarditis: a pivotal symptomatology and outcomes study) evaluated the efficacy and safety of rilonacept (IL-1α and -ß cytokine trap) in recurrent pericarditis. A secondary analysis of these data evaluated the patient-reported outcome questionnaire score change during the trial. Methods and Results Participants completed 5 patient-reported outcome (PRO) questionnaires assessing pericarditis pain, health-related quality of life, general health status, sleep impact, and overall symptom severity. PRO score changes during the treatment run-in period (12 weeks) and the blinded randomized withdrawal period (up to 24 weeks) were evaluated using descriptive statistics and mixed model repeated measures analyses. Participants with PRO data from the run-in period (n=84) and the randomized withdrawal period (n=61; 30 rilonacept, 31 placebo) were included in analyses. Run-in baseline PRO scores indicated that pericarditis symptoms during pericarditis recurrence impacted health-related quality of life. All PRO scores significantly improved (P<0.001) on rilonacept treatment during the run-in period. For the randomized withdrawal period, PRO scores were maintained for participants receiving rilonacept. For those receiving placebo and who experienced a recurrence, PRO scores deteriorated at the time of recurrence and then improved following rilonacept bailout. At randomized withdrawal Week 24/End of Study, scores of participants who received bailout rilonacept were similar to those of participants who had continued rilonacept. Conclusions These results demonstrate the burden of pericarditis recurrences and the improved physical and emotional health of patients with recurrent pericarditis while on rilonacept treatment. These findings extend prior rilonacept efficacy results, demonstrating improvements in patient-reported health-related quality of life, sleep, pain, and global symptom severity while on treatment.

Process study within a pilot cluster randomised trial in community pharmacy: An exploration of pharmacist readiness for research.

INTRODUCTION: Community pharmacies have an increasingly prominent public health function. This includes addressing alcohol, but guidance on delivery of alcohol interventions in this setting is lacking. We have developed an intervention that integrates attention to alcohol within existing community pharmacy medicine review services. This paper examines the experiences of community pharmacists (CPs) in conducting a pilot trial of the intervention, including the acceptability of the trial patient recruitment procedures and the training and support provided by the research team. METHOD: The pilot trial was conducted in 10 community pharmacies in Yorkshire, England. One CP from each pharmacy was recruited via a multi-stage process to assess motivation, commitment and capacity to participate. Each CP attended a research training day and received on-going research support to conduct the trial. Semi-structured audio-recorded face-to-face interviews (lasting 40-105 min) were conducted with all the CPs at the end of the trial. Data were also available from three direct observations conducted during trial support visits. Data were analysed thematically. RESULTS: The CPs were supportive of research in community pharmacy but had little direct experiences of research themselves. They valued the training and support provided, which had quickly identified areas where CPs were deviating from the study recruitment protocol. In some instances, the boundaries between research and practice became blurred with CPs making changes to their usual routines and interactions with patients to accommodate the research. CONCLUSIONS: The trial procedures were acceptable to CPs, in part because of the training and support provided. There are also identifiable areas where CPs' readiness for research could be enhanced to facilitate participation in future trials in this setting.

US Database Study of Clinical Burden and Unmet Need in Recurrent Pericarditis.

Background Patients with recurrent pericarditis (RP) may develop complications, multiple recurrences, or inadequate treatment response. This study aimed to characterize disease burden and unmet needs in RP. Methods and Results This retrospective US database analysis included newly diagnosed patients with RP with ≥24 months of continuous history following their first pericarditis episode. RP was defined as ≥2 pericarditis episodes ≥28 days apart. Some patients had ≥2 recurrences, while others had a single recurrence with a serious complication, ie, constrictive pericarditis, cardiac tamponade, or a large pericardial effusion with pericardiocentesis/pericardial window. Among these patients with multiple recurrences and/or complications, some had features relating to treatment history, including long-term corticosteroid use (corticosteroids started within 30 days of flare, continuing ≥90 consecutive days) or inadequate treatment response (pericarditis recurring despite corticosteroids and/or colchicine, or other drugs [excluding NSAIDs] within 30 days of flare, or prior pericardiectomy). Patients (N=2096) had hypertension (60%), cardiomegaly (9%), congestive heart failure (17%), atrial fibrillation (16%), autoimmune diseases (18%), diabetes mellitus (21%), renal disease (20%), anxiety (21%), and depression (14%). Complications included pericardial effusion (50%), cardiac tamponade (9%), and constrictive pericarditis (4%). Pharmacotherapy included colchicine (51%), NSAIDs (40%), and corticosteroids (30%), often in combination. This study estimates 37 000 US patients with RP; incidence was 6.0/100 000/year (95% CI, 5.6‒6.3), and prevalence was 11.2/100 000 (95% CI, 10.6‒11.7). Conclusions Patients with RP may have multiple recurrences and/or complications, often because of inadequate treatment response and persistent underlying disease. Corticosteroid use is frequent despite known side-effect risks, potentially exacerbated by prevalent comorbidities. Substantial clinical burden and lack of effective treatments underscore the high unmet need.

Disease and Economic Burden Associated with Recurrent Pericarditis in a Privately Insured United States Population.

INTRODUCTION: Approximately 30% of patients with a first acute pericarditis episode experience a recurrence ≤ 18 months; ~ 15% experience multiple recurrences. This study assessed the recurrence and economic burden among patients with multiple recurrences. METHODS: Adults with idiopathic pericarditis were identified in the OptumHealth Care Solutions, Inc., database (2007-2017). Recurrent pericarditis (RP) was defined as ≥ 2 episodes of care separated by > 28 days; multiple recurrences were defined as ≥ 2 recurrences. RESULTS: Among 944 patients with RP, 375 (39.7%) experienced multiple recurrences and were propensity score-matched 1:1 to 375 patients without recurrence. Among patients with multiple recurrences, median disease duration (time from first episode to end of last recurrence, confirmed by a 1.5-year recurrence-free period) was 2.84 years. The multiple recurrences cohort had higher rates of hospitalizations per-patient-per-month (PPPM) than the no recurrence cohort (rate ratio [95% confidence interval (CI)] = 2.22 [1.35-3.65]). Mean total healthcare costs were significantly higher in the multiple recurrences versus no recurrence cohort ($2728 vs. $1568 PPPM, cost ratio [95% CI] = 1.74 [1.29-2.32]), mainly driven by higher hospitalization costs in the multiple recurrences cohort (mean: $1180 vs. $420 PPPM, cost ratio [95% CI] = 2.81 [1.80-4.66]). Mean work loss costs were higher in the multiple recurrences versus no recurrence cohort ($696 vs. $169 PPPM, cost ratio [95% CI] = 4.12 [1.64-9.61]). In patients with multiple recurrences, mean cost of the first episode was $19,189; subsequent recurrences ranged from $2089 to $7366 (second recurrence = $6222). CONCLUSION: In conclusion, among patients with multiple pericarditis recurrences, disease symptoms persisted several years, and healthcare and work loss costs were further compounded in this subset of patients.

Burden of Recurrent Pericarditis on Health-Related Quality of Life.

The extent to which recurrences of pericarditis episodes impact patients' health-related quality of life (HRQOL) remains poorly understood. This study aimed to evaluate HRQOL and work productivity in patients with recurrent pericarditis (RP). Adult patients from a centralized recruitment database for the rilonacept Phase 2/3 clinical trials were invited to participate in a survey. Inclusion criteria were confirmed RP diagnosis and ≥1 recurrence within the previous 12 months. The 11-Point Pain Numeric Rating Scale, Patient Global Impression of Pericarditis Severity, Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health v1.2, PROMIS Short Form Sleep Disturbance 8b, Work Productivity and Activity Impairment v2.0, and customized questions about fear and economic impact were used. In total, 83 patients (55% female, average age = 49.3 years) completed the survey. The median time since pericarditis diagnosis was 3.0 years at the time of survey completion; 49% experienced ≥3 recurrences in the previous 12 months. Forty percent had an emergency room visit, and 25% were hospitalized for their most recent recurrence. Sixty-six percent of participants rated the symptoms of their last recurrence as severe. The mean value for worst pericarditis pain (0 to 10 scale) during the most recent recurrence was 6.1. The average T-scores for PROMIS physical and mental health were 37.6 and 42.8, respectively, compared with 50 in the general population. Participants reported 50% of overall work impairment and 62% of activity impairment due to RP. In conclusion, patients with RP experienced a high number of recurrences with severe symptoms that substantially reduced their HRQOL and work productivity.

Dupuytren's interventions surgery versus collagenase (DISC) trial: study protocol for a pragmatic, two-arm parallel-group, non-inferiority randomised controlled trial.

BACKGROUND: Dupuytren's contracture is a fibro-proliferative disease of the hands affecting over 2 million UK adults, particularly the white, male population. Surgery is the traditional treatment; however, recent studies have indicated that an alternative to surgery-collagenase clostridium histolyticum (collagenase)-is better than a placebo in the treatment of Dupuytren's contracture. There is however no robust randomised controlled trial that provides a definitive answer on the clinical effectiveness of collagenase compared with limited fasciectomy surgery. Dupuytren's intervention surgery vs collagenase trial (DISC) trial was therefore designed to fill this evidence gap. METHODS/DESIGN: The DISC trial is a multi-centre pragmatic two-arm parallel-group, randomised controlled trial. Participants will be assigned 1:1 to receive either collagenase injection or surgery (limited fasciectomy). We aim to recruit 710 adult participants with Dupuytren's contracture. Potential participants will be identified in primary and secondary care, screened by a delegated clinician and if eligible and consenting, baseline data will be collected and randomisation completed. The primary outcome will be the self-reported patient evaluation measure assessed 1 year after treatment. Secondary outcome measures include the Unité Rhumatologique des Affections de la Main Scale, the Michigan Hand Questionnaire, EQ-5D-5L, resource use, further procedures, complications, recurrence, total active movement and extension deficit, and time to return to function. Given the limited evidence comparing recurrence rates following collagenase injection and limited fasciectomy, and the importance of a return to function as soon as possible for patients, the associated measures for each will be prioritised to allow treatment effectiveness in the context of these key elements to be assessed. An economic evaluation will assess the cost-effectiveness of treatments, and a qualitative sub-study will assess participants' experiences and preferences of the treatments. DISCUSSION: The DISC trial is the first randomised controlled trial, to our knowledge, to investigate the clinical and cost-effectiveness of collagenase compared to limited fasciectomy surgery for patients with Dupuytren's contracture.
