Many barriers to scholarship have been identified, but there are limited data on which are most important. A rank-order of barriers from learners perspectives would better enable programs to address perceived barriers. Methods: Given that learners are experts in their own perceptions, we applied the Delphi method of generating consensus expert opinion to construct ranked lists of physician-perceived barriers to scholarly activity at various sites. The survey was conducted within three separate health systems. Respondents were asked to identify their perceived barriers via free text and the listed barriers were consolidated by the research team. In the second round, respondents were presented with the consolidated lists and asked to rank them. In the third and final round, each respondent was shown a comparison of their own rankings to that of their peers and given an opportunity to make changes. Ranking differences between programs were compared using Rank Biased Overlap (RBO).\u0000Results: The Delphi method is a straightforward method to obtain a ranked list of perceived learner barriers to scholarly activity; its primary limitation is learner engagement and, of note in our study, high dropout rates. RBO is an effective method of ranking differences between programs and specialties. Top barriers across programs included time, overwhelm with the research process, and lack of interest or energy. Discussion: Several of the identified barriers may be addressed with enthusiastic mentors, streamlined administrative processes, and education. This could be done within a hospital system or on a national level through specialty organizations.","PeriodicalId":501023,"journal":{"name":"medRxiv - Primary Care Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This trial sought to assess the feasibility and acceptability of supplying an electronic cigarette (e-cigarette) starter kit for smoking cessation as an adjunct to usual care for smoking cessation, to smokers with a mental health condition treated in the community, to inform a future effectiveness trial.\u0000Methods: This randomised controlled feasibility trial, conducted March-December 2022, compared the intervention (e-cigarette starter kit with a corresponding information leaflet and demonstration with Very Brief Advice) with a usual care control at 1-month follow-up. Participants were 18+ years, receiving treatment for any mental health condition in primary or secondary care in three Mental Health Trusts in Yorkshire and one in London, UK. They were also willing to address their smoking through either cessation or reduction of cigarette consumption. The agreed primary outcome measure was feasibility (consent~15% of eligible participants; attrition rate<30%). Acceptability, validated sustained abstinence and at least 50% cigarette consumption reduction at 1-month, were also evaluated and qualitative interviews conducted to further explore acceptability in this population.\u0000Results: Feasibility targets were partially met; of 201 eligible participants, 43 (mean age = 45.2, SD = 12.7; 39.5% female) were recruited (21.4%) and randomised (intervention:48.8%, n=21; control:51.2%, n=22). Attrition rate was 37.2% at 1-month follow-up and was higher (45.5%) in the control group. At follow-up (n=27), 93.3% (n=14) in the intervention group and 25.0% (n=3) in the control group reported e-cigarette use. The intervention was well received with minimal negative effects. In intention-to-treat analysis, validated sustained abstinence at 1-month was 2/21 (9.5%) and 0/22 (0%) and at least 50% reduction in cigarette consumption 13/21 (61.9%) and 3/22 (13.6%), for the intervention and control group, respectively. Qualitative analysis of participant interviews (N=5) showed the intervention was broadly acceptable, but they also highlighted areas of improvements for the intervention and trial delivery.\u0000Conclusions: Offering an e-cigarette starter kit to smokers with a mental health condition treated in the community was acceptable and largely feasible, with harm reduction outcomes (i.e. switching from cigarette smoking to e-cigarette use and substantial reduction in cigarette consumption) favouring the intervention. The findings of the study will be used to help inform the design of a main trial.","PeriodicalId":501023,"journal":{"name":"medRxiv - Primary Care Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A cross-sectional study utilizing an anonymous, self administered questionnaire was given to General Practitioners, Family Medicine, and Internal Medicine physicians after using a simple random sampling approach. Descriptive and inferential statistical analysis was conducted using IBM SPSS software. Results: There were 119 physicians in this study with Family Medicine specialty area representing 52.1%. Seventy-four (74) physicians reported following CKD guidelines. The most common at-risk groups identified were Diabetes Mellitus (100%), Hypertension (98.3%), and use of nephrotoxic agents (97.5%). The most common diagnostic test used to identify CKD was eGFR (97.5%) and 72.2% of physicians used eGFR alone to stage CKD.

The purpose of this study is to examine the impact that ambulatory care clinical pharmacy specialists (CPSs) had on initiation of first-line antihypertensives in the African American population within an integrated healthcare system. Methods This retrospective, matched, observational cohort analysis included African American patients with hypertension not receiving a first-line antihypertensive as of September 1, 2021. Patients followed by CPSs were matched up to 1:4 on age and sex to patients not followed by CPSs. The primary outcome was the percentage of patients started on first-line antihypertensive(s) after working with CPSs. Conditional logistic regression was used to analyze outcomes. Results\u0000A total of 865 patients followed by CPSs were matched to 3,192 patients not followed by CPSs.

Primary care electronic health records provide a rich source of information for inequalities research. However, the reliability and validity of the research derived from these records depends on the completeness and resolution of the codelists used to identify marginalised populations. Aim. The aim of this project was to develop comprehensive codelists for identifying ethnic minorities, people with learning disabilities (LD), people with severe mental illness (SMI) and people who are transgender. Design and setting. This study was a codelist development project, conducted using primary care data from the United Kingdom. Method. Groups of interest were defined a priori. Relevant clinical codes were identified by searching Clinical Practice Research Datalink (CPRD) publications, codelist repositories and the CPRD code browser. Relevant codelists were downloaded and merged according to marginalised group. Duplicates were removed and remaining codes reviewed by two general practitioners. Comprehensiveness was assessed in a representative CPRD population of 10,966,759 people, by comparing the frequencies of individuals identified when using the curated codelists, compared to commonly used alternatives. Results. A total of 52 codelists were identified. 1,420 unique codes were selected after removal of duplicates and GP review. Compared with comparator codelists, an additional 48,017 (76.6%), 52,953 (68.9%) and 508 (36.9%) people with a LD, SMI or transgender code were identified.

Design, Setting and Methods: An online survey of 192 GPs in Australia who treated adolescents (12 to 17 years old) with depression and/or anxiety.\u0000Results: GPs frequently referred adolescents with depression and/or anxiety to psychologists.

The frequency of medication prescribing almost doubled during the wait time when compared to routine practice (14.6% versus 8.3%, respectively). Almost all GPs (81.8%) increased their level of care due to long wait times but had limited training in youth mental health and knowledge on appropriate strategies to do so effectively. Conclusion: The findings signify the discrepancies between the preferences of GPs for treatment availability in Australia and what they see as the experience for many adolescents with depression and/or anxiety who are referred to specialist care.

However, the detection of proteins is equally critical across diverse applications in biology, medicine, and the food industry, especially for diagnosing and prognosing diseases like cancer, Alzheimer and cardiovascular conditions. Despite recent efforts to adapt CRISPR/Cas systems for protein detection with immunoassays, these methods typically achieved sensitivity only in the femtomolar to picomolar range, underscoring the need for enhanced detection capabilities. To address this, we developed CRISPR-AMPED, an innovative CRISPR/Cas-based immunoassay enhanced by magnetic proximity extension and detection. This approach combines proximity extension assay (PEA) with magnetic beads that converts protein into DNA barcodes for quantification with effective washing steps to minimize non-specific binding and hybridization, therefore reducing background noise and increasing detection sensitivity. The resulting DNA barcodes are then detected through isothermal nucleic acid amplification testing (NAAT) using recombinase polymerase amplification (RPA) coupled with the CRISPR/Cas12a system, replacing the traditional PCR. This integration eliminates the need for thermocycling and bulky equipment, reduces amplification time, and provides simultaneous target and signal amplification, thereby significantly boosting detection sensitivity. CRISPR-AMPED achieves attomolar level sensitivity, surpassing ELISA by over three orders of magnitude and outperforming existing CRISPR/Cas-based detection systems. Additionally, our smartphone-based detection device demonstrates potential for point-of-care applications, and the digital format extends dynamic range and enhances quantitation precision. We believe CRISPR-AMPED represents a significant advancement in the field of protein detection.","PeriodicalId":501023,"journal":{"name":"medRxiv - Primary Care Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
