Primary care micro-teams: a protocol for an international systematic review to describe and examine the opportunities and challenges of implementation for patients and healthcare professionals

Introduction: There has been a recent trend towards creating larger primary care practices with the assumption that interdisciplinary teams can deliver improved and more cost-effective services to patients with better accessibility. Micro-teams have been proposed to mitigate some of the potential challenges with practice expansion, including continuity of care. We aim to review the available literature to improve understanding of how micro-teams are described and the opportunities which primary care micro-teams can provide for practice staff and patients and limitations to their introduction and implementation. Our review asks: how is micro-team implementation described? What are the experiences of healthcare professionals and patients concerning micro-teams in primary care? What are the reported implications of micro-teams for patient care? // Methods and analysis: CINAHL, Cochrane Library, Embase, MEDLINE and Scopus will be searched for studies in English. Grey literature will be sourced from Google Scholar, government websites, CCG websites, general practice directives and strategies with advice from stakeholders. Included studies will give evidence regarding the implementation of micro-teams. Data will be synthesised using framework analysis. We will use iterative stakeholder and public and patient participation to embed the perspectives of those whom micro-teams could impact. Included studies will be quality assessed using the Mixed Methods Appraisal Tool. The quality assessment will not be used to exclude any evidence but rather to develop a narrative discussion evaluating included literature. // Ethics and dissemination: Ethical approval will not be necessary for this systematic review as there will only be a secondary analysis of data already available in scientific databases and the grey literature. This protocol has been submitted for registration to be made available on a review database (PROSPERO). Findings will be disseminated widely through peer-reviewed publication and in various media, for example, conferences, congresses or symposia

Opportunities, challenges and implications of primary care micro-teams for patients and healthcare professionals: an international systematic review

Background: There has been a recent trend, both in the UK and internationally, towards creating larger primary care practices with the assumption that interdisciplinary teams can increase patient accessibility and provide more cost-effective, efficient services. Micro-teams have been proposed to mitigate some of the potential challenges with practice expansion, including continuity of care. / Aim: Review the available literature to examine how micro-teams are described and the opportunities which primary care micro-teams can provide for practice staff and patients and limitations to their introduction and implementation. / Design and setting: International Systematic review of studies published in English. / Method: A Framework analysis was used to synthesise the literature. Databases and grey literature were searched. Studies were included if they provided evidence regarding the implementation of micro-teams in primary care. We worked with a PPI co-author and conducted stakeholder discussions to those with and without experience in micro-team implementation. / Results: The majority of the 24 included studies discussed empirical data from healthcare professionals, describing the implementation of micro-teams. Results include the characteristics of the literature; how micro-teams have been described; the range of ways micro-teams have been implemented; reported outcomes and experiences of patients and staff. / Conclusion: The organisation of primary care has the potential to impact the nature and quality of patient care, safety and outcomes. This review contributes to current debates surrounding care delivery and how this can impact the experiences and outcomes of patients and staff. The analysis identifies several key opportunities and challenges for future research, policy and practice

Phytochemical investigations, in-vitro antioxidant, antimicrobial potential, and in-silico computational docking analysis of Euphorbia milii Des Moul

Euphorbia milii Des Moul is a deciduous bush indigenous to Madagascar. The present study aims to investigate the presence of the phytochemical, in-vitro antioxidant and antimicrobial potency, and in-silico computational analysis of ethanolic and aqueous preparations of E. milii leaves and flowers. The ethanolic and aqueous extracts were tested for in-vitro antioxidant activity by DPPH, H2O2, TAC, and FRAP assay. In addition, antimicrobial potentials were assayed by agar well diffusion technique against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, and Candida albicans for various clinical isolates. The qualitative phytochemical analysis results confirmed the existence of alkaloids, flavonoids, phenolics, and tannins. The quantitative analysis elicits the availability of a magnificent number of alkaloids, flavonoids, phenolics, flavonols, and tannins. Among all the extracts, aqueous extracts of leaves exhibited potent antioxidant activity in DPPH, FRAP, and H2O2 assay with the IC50 value of 30.70, 60.05, and 82.92µg/mL, respectively. In agar well diffusion assay, all extracts displayed zone of inhibition varies from 2-24mm at different concentrations ranging from 10-320 mg/mL, whereas no activity was observed against Candida albicans. Furthermore, docking-based computational analysis has revealed that beta-sitosterol and taraxerol are the plant's active constituents responsible for their antimicrobial and antioxidant activities. Research findings suggest that the E. milii plant has an excellent prospect for further study for its extended antioxidative and antimicrobial potential. It could be a natural source of various ailments and can be utilized to develop new drugs

Persistent neuropsychiatric symptoms after COVID-19: a systematic review and meta-analysis.

The nature and extent of persistent neuropsychiatric symptoms after COVID-19 are not established. To help inform mental health service planning in the pandemic recovery phase, we systematically determined the prevalence of neuropsychiatric symptoms in survivors of COVID-19. For this pre-registered systematic review and meta-analysis (PROSPERO ID CRD42021239750), we searched MEDLINE, EMBASE, CINAHL and PsycINFO to 20 February 2021, plus our own curated database. We included peer-reviewed studies reporting neuropsychiatric symptoms at post-acute or later time-points after COVID-19 infection and in control groups where available. For each study, a minimum of two authors extracted summary data. For each symptom, we calculated a pooled prevalence using generalized linear mixed models. Heterogeneity was measured with I 2. Subgroup analyses were conducted for COVID-19 hospitalization, severity and duration of follow-up. From 2844 unique titles, we included 51 studies (n = 18 917 patients). The mean duration of follow-up after COVID-19 was 77 days (range 14-182 days). Study quality was most commonly moderate. The most prevalent neuropsychiatric symptom was sleep disturbance [pooled prevalence = 27.4% (95% confidence interval 21.4-34.4%)], followed by fatigue [24.4% (17.5-32.9%)], objective cognitive impairment [20.2% (10.3-35.7%)], anxiety [19.1% (13.3-26.8%)] and post-traumatic stress [15.7% (9.9-24.1%)]. Only two studies reported symptoms in control groups, both reporting higher frequencies in COVID-19 survivors versus controls. Between-study heterogeneity was high (I 2 = 79.6-98.6%). There was little or no evidence of differential symptom prevalence based on hospitalization status, severity or follow-up duration. Neuropsychiatric symptoms are common and persistent after recovery from COVID-19. The literature on longer-term consequences is still maturing but indicates a particularly high prevalence of insomnia, fatigue, cognitive impairment and anxiety disorders in the first 6 months after infection

Liquid Biopsy in Gastrointestinal Cancers

Liquid biopsy is the sampling of any biological fluid in an effort to enrich and analyze a tumor’s genetic material. Peripheral blood remains the most studied liquid biopsy material, with circulating tumor cells (CTC’s) and circulating tumor DNA (ctDNA) allowing the examination and longitudinal monitoring of a tumors genetic landscape. With applications in cancer screening, prognostic stratification, therapy selection and disease surveillance, liquid biopsy represents an exciting new paradigm in the field of cancer diagnostics and offers a less invasive and more comprehensive alternative to conventional tissue biopsy. Here, we examine liquid biopsies in gastrointestinal cancers, specifically colorectal, gastric, and pancreatic cancers, with an emphasis on applications in diagnostics, prognostics and therapeutics
