Lessons Learned in the Early Stages of a Community-Academic Partnership to Address Health Disparities in a Rural Community

In rural Georgia, African American men are burdened by chronic health diseases such as cancer, diabetes, and cardiovascular disease. Community-academic partnerships that leverage community-based participatory research (CBPR) principles can facilitate the adaptation and translation of multilevel programs to address chronic disease prevention and management in rural areas. The objective of this study was to explore key components of the CBPR process that bolstered the early stages of a partnership established between rural-residing community leaders and academic partners in Georgia. Qualitative methodology was used to collect and assess data regarding the initial engagement between the community and academic partners. Findings indicate that five components supported initial engagement: utilizing the public service and outreach arm of the university to connect with rural communities; creating synergy around identified community health needs; encouraging community members to provide input into the research design to ensure the research goals reflect community values; enhancing the capacity of community partners; and following the lead of the community. Findings provide insights into how to begin engaging rural communities in the southeast in order to strengthen the adaptation and translation of initiatives to improve cancer, diabetes and cardiovascular disease outcomes

Maintenance therapy with once-monthly administration of long-acting injectable risperidone in patients with schizophrenia or schizoaffective disorder: a pilot study of an extended dosing interval

BACKGROUND: Several clinical studies have established the efficacy, safety, and tolerability of long-acting risperidone administered once every 2 weeks in patients with schizophrenia or schizoaffective disorder. This report evaluates preliminary efficacy, safety, tolerability, and pharmacokinetic data for a novel (once-monthly) administration of long-acting injectable risperidone 50 mg in patients with schizophrenia or schizoaffective disorder. METHODS: Clinically stable patients participated in a 1-year, open-label, single-arm, multicenter pilot study. During the 4-week lead-in phase, patients received long-acting risperidone 50 mg injections every 2 weeks, with 2 weeks of oral risperidone supplementation. Injections of long-acting risperidone 50 mg every 4 weeks followed for up to 48 weeks, without oral supplementation. The primary endpoint was relapse; other assessments included PANSS, CGI-S, adverse event reports, and determination of risperidone and 9-hydroxyrisperidone plasma concentrations. RESULTS: Twelve patients in the intent-to-treat population (n = 67) met relapse criteria (17.9%). Relapse risk at 1 year was estimated as 22.4%. Non-statistically significant improvements in symptoms (PANSS) and clinical status (CGI-S) at endpoint were observed. The most common adverse events included schizophrenia aggravated not otherwise specified (19.5%), anxiety (16.1%), insomnia (16.1%), and headache (11.5%). There were no unexpected safety and tolerability findings. Mean plasma concentrations for risperidone and 9-hydroxyrisperidone were generally stable during the study. CONCLUSION: Once-monthly dosing of long-acting risperidone was well tolerated, associated with a relatively low relapse rate (similar to that reported with other antipsychotics), and maintained the clinically stable baseline status of most patients. Although the results suggest that some symptomatically stable patients with schizophrenia or schizoaffective disorder might be safely managed with long-acting risperidone 50 mg once monthly, these findings alone do not identify which patients will have a sufficient therapeutic benefit nor do they quantify comparative effects of standard and altered dosing. Study limitations (the open-label pilot study design, small sample size, and lack of a concurrent biweekly treatment arm) prevent broad interpretations and extrapolations of results. Controlled studies would be required to support a recommendation for alternative dosing regimens

Exoplanet Diversity in the Era of Space-based Direct Imaging Missions

This whitepaper discusses the diversity of exoplanets that could be detected by future observations, so that comparative exoplanetology can be performed in the upcoming era of large space-based flagship missions. The primary focus will be on characterizing Earth-like worlds around Sun-like stars. However, we will also be able to characterize companion planets in the system simultaneously. This will not only provide a contextual picture with regards to our Solar system, but also presents a unique opportunity to observe size dependent planetary atmospheres at different orbital distances. We propose a preliminary scheme based on chemical behavior of gases and condensates in a planet's atmosphere that classifies them with respect to planetary radius and incident stellar flux.Comment: A white paper submitted to the National Academy of Sciences Exoplanet Science Strateg

CONservative TReatment of Appendicitis in Children – a randomised controlled feasibility Trial (CONTRACT)

Objective To establish the feasibility of a multicentre randomised controlled trial to assess the effectiveness and cost-effectiveness of a non-operative treatment pathway compared with appendicectomy in children with uncomplicated acute appendicitis.Design Feasibility randomised controlled trial with embedded qualitative study to inform recruiter training to optimise recruitment and the design of a future definitive trial.Setting Three specialist paediatric surgery centres in the UK.Patients Children (aged 4–15 years) with a clinical diagnosis of uncomplicated acute appendicitis.Interventions Appendicectomy or a non-operative treatment pathway (comprising broad-spectrum antibiotics and active observation).Main outcome measures Primary outcome measure was the proportion of eligible patients recruited. Secondary outcomes evaluated adherence to interventions, data collection during follow-up, safety of treatment pathways and clinical course.Results Fifty per cent of eligible participants (95% CI 40 to 59) approached about the trial agreed to participate and were randomised. Repeated bespoke recruiter training was associated with an increase in recruitment rate over the course of the trial from 38% to 72%. There was high acceptance of randomisation, good patient and surgeon adherence to trial procedures and satisfactory completion of follow-up. Although more participants had perforated appendicitis than had been anticipated, treatment pathways were found to be safe and adverse event profiles acceptable.Conclusion Recruitment to a randomised controlled trial examining the effectiveness and cost-effectiveness of a non-operative treatment pathway compared with appendicectomy for the treatment of uncomplicated acute appendicitis in children is feasible.Trial registration number ISRCTN15830435

microRNA-seq of cartilage reveals an over-abundance of miR-140-3p which contains functional isomiRs

miR-140 is selectively expressed in cartilage. Deletion of the entire Mir140 locus in mice results in growth retardation and early-onset osteoarthritis-like pathology; however, the relative contribution of miR-140-5p or miR-140-3p to the phenotype remains to be determined. An unbiased small RNA sequencing approach identified miR-140-3p as significantly more abundant (>10-fold) than miR-140-5p in human cartilage. Analysis of these data identified multiple miR-140-3p isomiRs differing from the miRBase annotation at both the 5' and 3' end, with >99% having one of two seed sequences (5' bases 2-8). Canonical (miR-140-3p.2) and shifted (miR-140-3p.1) seed isomiRs were overexpressed in chondrocytes and transcriptomics performed to identify targets. miR-140-3p.1 and miR-140-3p.2 significantly down-regulated 694 and 238 genes, respectively, of which only 162 genes were commonly down-regulated. IsomiR targets were validated using 3'UTR luciferase assays. miR-140-3p.1 targets were enriched within up-regulated genes in rib chondrocytes of Mir140- null mice and within down-regulated genes during human chondrogenesis. Finally, through imputing the expression of miR-140 from the expression of the host gene WWP2 in 124 previously published data sets, an inverse correlation with miR-140-3p.1 predicted targets was identified. Together these data suggest the novel seed containing isomiR miR-140- 3p.1 is more functional than original consensus miR-140-3p seed containing isomiR

The microRNA-29 family in cartilage homeostasis and osteoarthritis

MicroRNAs have been shown to function in cartilage development and homeostasis, as well as in progression of osteoarthritis. The objective of the current study was to identify microRNAs involved in the onset or early progression of osteoarthritis and characterise their function in chondrocytes. MicroRNA expression in mouse knee joints post-DMM surgery was measured over 7 days. Expression of miR-29b-3p was increased at day 1 and regulated in the opposite direction to its potential targets. In a mouse model of cartilage injury and in end-stage human OA cartilage, the miR-29 family were also regulated. SOX9 repressed expression of miR-29a-3p and miR-29b-3p via the 29a/b1 promoter. TGFβ1 decreased expression of miR-29a, b and c (3p) in primary chondrocytes, whilst IL-1β increased (but LPS decreased) their expression. The miR-29 family negatively regulated Smad, NFκB and canonical WNT signalling pathways. Expression profiles revealed regulation of new WNT-related genes. Amongst these, FZD3, FZD5, DVL3, FRAT2, CK2A2 were validated as direct targets of the miR-29 family. These data identify the miR-29 family as microRNAs acting across development and progression of OA. They are regulated by factors which are important in OA and impact on relevant signalling pathways

Conservative treatment for uncomplicated appendicitis in children:the CONTRACT feasibility study, including feasibility RCT

Background Whilst non-operative treatment is known to be effective for the treatment of uncomplicated acute appendicitis in children, comparative randomised trial data reporting important outcomes compared to appendicectomy are lacking.ObjectivesTo ascertain the feasibility of conducting a multi-centre randomised controlled trial (RCT) testing the effectiveness and cost-effectiveness of a non-operative treatment pathway compared to appendicectomy for the treatment of uncomplicated acute appendicitis in children.•DesignMixed methods study including: a feasibility RCT; embedded and parallel qualitative and survey studies; parallel health economic feasibility study; development of a core outcome set.Setting Three specialist NHS Paediatric Surgical Units in EnglandParticipants Children (aged 4-15 years) clinically diagnosed with uncomplicated acute appendicitis participated in the feasibility RCT. Children, their families, recruiting clinicians and other healthcare professionals involved in caring for children with appendicitis took part in the qualitative study. UK Specialist Paediatric Surgeons took part in the survey. Specialist Paediatric Surgeons, Adult General Surgeons who treat children, and children and young people who previously had appendicitis along with their families took part in the core outcomes set development.Interventions Participants in the feasibility RCT were randomised to a non-operative treatment pathway (broad-spectrum antibiotics and active observation) or appendicectomy.Main outcome measures Primary outcome measure was the proportion of eligible patients recruited to the feasibility trial.Data sourcesNHS casenotes, questionnaire responses, transcribed audio recordings of recruitment discussions and qualitative interviewsResults Overall, 50% (95%CI 40-59) of 115 eligible participants approached about the trial agreed to participate and were randomised. There was high acceptance of randomisation and good adherence to trial procedures and follow-up (follow rates of 89%, 85% and 85% at six weeks, three months and six months respectively). More participants had perforated appendicitis than had been anticipated.Qualitative work enabled us to: communicate about the trial effectively with patients and families; design and deliver bespoke training to optimise recruitment; and understand how to optimise design and delivery of a future trial.The health economic study, indicated that the main cost drivers are the ward stay cost and the cost of the operation, and has informed quality of life assessment methods for future work.A core outcome set for the treatment of uncomplicated acute appendicitis in children and young people was developed, containing 14 outcomes.There is adequate surgeon interest to justify proceeding to an effectiveness trial with 51% of those surveyed expressing a willingness to recruit with an unchanged trial protocol.LimitationsSince the feasibility RCT was only performed in three centres we cannot guarantee successful recruitment across a larger number of sites. However, our qualitative work has informed a bespoke training package to facilitate this. Although survey results suggest adequate clinician interest to make a larger trial possible, actual participation may differ, and equipoise may have moved over time.Conclusions A future effectiveness trial is feasible following limited additional preparation to establish appropriate outcome measures and case identification. We recommend a limited package of qualitative work be included to optimise recruitment at new centres in particular.Future work Prior to proceeding to an effectiveness trial we need to: develop a robust method for distinguishing children with uncomplicated acute appendicitis from those with more advanced appendicitis; reach agreement on a primary outcome measure and effect size that is acceptable to all stakeholder groups involved.Study registration ISRCTN15830435.Funding detailsNIHR HTA programm
