FcRn plays a major role in regulating immune homeostasis, but it is also able to transport biologics across cellular barriers. The question of whether FcRn could be an efficient transporter of biologics across the nasal epithelial barrier is of particular interest, as it would allow a less invasive strategy for the administration of biologics in comparison to subcutaneous, intramuscular or intravenous administrations, which are often used in clinical practice. A focused systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. It was registered on the international prospective register of systematic reviews PROSPERO, which helped in identifying articles that met the inclusion criteria. Clinical and preclinical studies involving FcRn and the nasal delivery of biologics were screened, and the risk of bias was assessed across studies using the Oral Health Assessment Tool (OHAT). Among the 12 studies finally included in this systematic review (out of the 758 studies screened), 11 demonstrated efficient transcytosis of biologics through the nasal epithelium. Only three studies evaluated the potential toxicity of biologics’ intranasal delivery, and they all showed that it was safe. This systematic review confirmed that FcRn is expressed in the nasal airway and the olfactory epithelium, and that FcRn may play a role in IgG and/or IgG-derived molecule-transcytosis across the airway epithelium. However, additional research is needed to better characterize the pharmacokinetic and pharmacodynamic properties of biologics after their intranasal delivery.

BACKGROUND: The mental health of medical students has long been a topic of concern in many countries. Much research in Europe reported that around 30% of medical students suffered from anxiety. Anxiety disorders have significant physical and emotional consequences. Various studies show that excessive, unmanaged stress related to poor academic performance in medical students leads to cynical personalities, lack of empathy, and suicidal ideas. AIM: This study aimed to identify studies for psychotherapy interventions carried out in medical students and analyze each impact on anxiety level in medical students. METHODS: This systematic review was conducted with evidence sourced from 2000 to 2020. The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The study was registered with the Prospective Registering of Systematic Reviews database (Protocol ID: CRD42020180650). RESULTS: Twenty-three studies meet the inclusion criteria, and there are various psychotherapy interventions to deal with anxiety. Most studies reported that students who received mindfulness-based interventions reported lower anxiety, depression, and stress. CONCLUSION: There are various interventions carried out to decrease stress levels, depression, and anxiety in medical students. The most effective psychotherapy was found in cognitive and behavior intervention and mindfulness intervention.

Abstract Background Augmented reality (AR) uses a set of technologies that overlays digital information into the real world, giving the user access to both digital and real-world environments in congruity. AR may be specifically fruitful in reconstructive microsurgery due to the dynamic nature of surgeries performed and the small structures encountered in these operations. The aim of this study was to conduct a high-quality preferred reporting items for systematic reviews and meta-analyses (PRISMA) and assessment of multiple systematic reviews 2 (AMSTAR 2) compliant systematic review evaluating the use of AR in reconstructive microsurgery. Methods A systematic literature search of Medline, EMBASE, and Web of Science databases was performed using appropriate search terms to identify all applications of AR in reconstructive microsurgery from inception to December 2018. Articles that did not meet the objectives of the study were excluded. A qualitative synthesis was performed of those articles that met the inclusion criteria. Results A total of 686 articles were identified from title and abstract review. Five studies met the inclusion criteria. Three of the studies used head-mounted displays, one study used a display monitor, and one study demonstrated AR using spatial navigation technology. The augmented reality microsurgery score was developed and applied to each of the AR technologies and scores ranged from 8 to 12. Conclusion Although higher quality studies reviewing the use of AR in reconstructive microsurgery is needed, the feasibility of AR in reconstructive microsurgery has been demonstrated across different subspecialties of plastic surgery. AR applications, that are reproducible, user-friendly, and have clear benefit to the surgeon and patient, have the greatest potential utility. Further research is required to validate its use and overcome the barriers to its implementation.

Objective: To identify, appraise and synthesize research on the interventions used in child to parent violence. Method: A systematic literature review was conducted using the electronic databases of PsycINFO, Scopus, Web of Science and CINAHL Full Text. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, three authors conducted the screening process which was implemented in two stages including screening the title and abstract, followed by screening the full text. Papers were assessed for quality using the Mixed Methods Assessment Tool. The search identified 727 studies which met the inclusion criteria, deduplication resulted in 525 number for review, with 8 articles included in the review. Results: This review identifies six themes from the six unique interventions included to address the research questions: How do practitioners effectively support families experiencing child-to-parent violence? The six themes are: Conceptualising the violence; Assessment of needs and risks; Intervention types and settings; Program techniques and components of interventions; Intervention outcomes and effectiveness; and Research design and methods. Three narratives were iteratively developed from these themes which highlight the main findings of the review: importance of the practitioner and their skills; conceptual clarity of CPV; and CPV interventions. Conclusions: The findings from this systematic review identifies the need for further research into child to parent violence including what makes interventions effective, what needs and outcomes the interventions are addressing, and the implications of classifications of this violence.

This systematic review and meta-analysis examined the effectiveness of parent–infant interventions for parents of preterm infants on parental sensitivity compared to standard care or active comparators. This review follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and was prospectively registered in the International Prospective Register of Systematic Reviews (PROSPERO; registration ID: CRD42016047083). Database searches were performed from inception to 2020 to identify eligible randomized controlled trials. Two review authors independently selected studies, extracted data, and assessed the risk of bias using the Cochrane risk of bias assessment tool and quality of evidence using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) guidelines. A total of 19 studies ( n = 2,111 participants) were included and 14 were suitable to be pooled in our primary outcome meta-analysis. Results show no significant effect of parent–infant interventions over standard care or basic educational programs, on parental sensitivity. Results may not necessarily be due to the ineffectiveness of the interventions but rather due to implementation failure or high risk of bias of included studies.

Introduction:Impacted third molars (I3Ms) are blocked from fully erupting; many I3Ms are asymptomatic, however there could be pain and pathological changes. Historically, I3Ms were removed prophylactically. Current options in the United Kingdom include either retention with standard care (watchful waiting), or removal due to pathological changes. We conducted a systematic review of the prophylactic removal of asymptomatic impacted mandibular third molars (IM3Ms) compared with standard care.Methods:We searched five electronic databases from 1999 onwards. Inclusion criteria: randomized and non-randomized trials, observational studies, and systematic reviews (SRs) comparing the prophylactic removal of IM3Ms with standard care or studies assessing the outcomes of either approach; outcomes included pathology associated with retention, postoperative complications, adverse effects of treatment and health-related quality of life. Two reviewers independently screened all titles and/or abstracts, applied inclusion criteria to potentially relevant publications, and quality assessed and data extracted the included studies. No meta-analysis or network meta-analyses were undertaken.Results:Following screening of 11,373 references, 13 studies (four cohort studies and nine SRs) were included. One cohort study investigated the prophylactic removal of asymptomatic IM3Ms in comparison with standard care and retention, two investigated the prophylactic removal of asymptomatic IM3Ms, and one studied the retention and standard care of asymptomatic IM3Ms. Two studies reporting surgical complications found no serious complications; however, one study reported intense pain and postoperative infection. Pathological changes due to retention of asymptomatic IM3Ms were reported by three studies. Nine SRs of the management of third molars were included in this review, however none focused solely on IM3Ms.Conclusions:Consistent with previous systematic reviews, we found no RCT data to support or refute the prophylactic removal of asymptomatic IM3Ms, despite extensive searching of the literature. The review however did identify evidence from two longitudinal studies demonstrating the outcomes when asymptomatic IM3Ms are left in situ.

Objective Evaluate the influence of prenatal care on the occurrence of gestational hypertension. Methods The Web of Science, Scopus, Pubmed, Cochrane and ClinicalTrials electronic databases were searched for articles published between January 1st, 2012 and December 31st, 2016. No language restrictions were imposed. The following keywords were used: prenatal care, medical assistance, prenatal education, pregnancy-induced hypertension. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) checklist was employed. Two hundred and forty articles were identified during the initial search, but only seven met the inclusion criteria. This systematic review is registered with the international prospective register of systematic reviews (PROSPERO; #CRD42017064103). Results The seven studies had a low risk of bias, with methodological quality scores ranging from six to eight points. Five studies found a positive relationship between prenatal care and pregnancy-induced hypertension, whereas two studies found no significant association between the two variables. The divergence among the studies may have been due to the type of healthcare service at which the study was conducted and the sample size. Conclusion Although the studies analyzed differed with regard to methodological aspects, the findings demonstrate the importance of prenatal care during the gestational period as a prevention and health promotion measure.

Background: Natural products are commonly used for treating health problems. These products may be associated with adverse events, which are defined as "noxious and unintended response to a medicinal product" by the European Medicine Agency. Objectives: To identify studies describing at least one adverse event (or with potential to promote an adverse event) related to the use of natural products, as well as to describe the involved product(s) and adverse event(s). Methods: A pre-systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Keywords: "natural product(s)" and ["adverse drug reaction(s)" or "adverse effect(s)"]. Screened databases: PubMed, SciELO, DOAJ and Google Scholar. Inclusion criteria: papers describing at least one adverse event associated with the use of natural products and published between 2017 and 2019. Exclusion criteria: Repeated studies, reviews and papers written in other languages than English, Portuguese, French or Spanish. Results: 104 studies were identified (20 PubMed; 0 SciELO; 2 DOAJ; 82 Google Scholar), but only 10 were selected (4 PubMed and 6 Google Scholar): 1 in-vitro study; 2 non-clinical studies, 1 study reporting in-vitro and clinical data and 5 studies were cases reports. Globally, 997 reports of adverse drug reactions with natural products were identified, mainly non-severe cases. Conclusion: Since a limited number of studies was found, we conclude that adverse events due to natural products may be underreported, or natural products may have a good safety profile. This review contributes for assuring the safety of natural products consumers, by evaluating the knowledge/information on the potential adverse events and interactions of these products.

ObjectiveTo critically appraise the quality of published systematic reviews (SRs) of randomised controlled trials (RCTs) in tendinopathy with regard to handling and reporting of results with special emphasis on strength of evidence assessment.Data sourcesMedline from inception to June 2020.Study eligibilityAll SRs of RCTs assessing the effectiveness of any intervention(s) on any location of tendinopathy.Data extraction and synthesisIncluded SRs were appraised with the use of a 12-item tool devised by the authors arising from the Preferred Reporting Items in Systematic Reviews and Meta-Analyses statement and other relevant guidance. Subgroup analyses were performed based on impact factor (IF) of publishing journals and date of publication.ResultsA total of 57 SRs were included published in 38 journals between 2006 and 2020. The most commonly used risk-of-bias (RoB) assessment tool and strength of evidence assessment tool were the Cochrane Collaboration RoB tool and the Cochrane Collaboration Back Review Group tool, respectively. The mean score on the appraisal tool was 46.5% (range 0%–100%). SRs published in higher IF journals (>4.7) were associated with a higher mean score than those in lower IF journals (mean difference 26.4%±8.8%, p=0.004). The mean score of the 10 most recently published SRs was similar to that of the first 10 published SRs (mean difference 8.3%±13.7%, p=0.54). Only 23 SRs (40%) used the results of their RoB assessment in data synthesis and more than half (n=30; 50%) did not assess the strength of evidence of their results. Only 12 SRs (21%) assessed their strength of evidence appropriately.ConclusionsIn light of the poor presentation of evidence identified by our review, we provide recommendations to increase transparency and reproducibility in future SRs.
