Introduction: Although healing abutments are designated for single use by most implant manufacturers, it is common practice for clinicians to reuse healing abutments. However, there is a lack of adequate references that describe detailed sterilization protocols for reuse of healing abutments. Objectives: The purpose of this systematic review was to compile, organize, and describe the most common techniques for the sterilization of healing abutments and their efficiency in eliminating traces of microorganisms. Methods: An electronic search in 5 different databases was performed, including the National Library of Medicine (MEDLINE via PubMed), Embase, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar from January 2000 to December 2020. Search variables included were dental implant, healing abutment, contaminate, contamination, reuse, and sterilization. Studies reporting with a minimum sample size of 10 healing abutments (5 per group) published in the English language were evaluated. Risk of bias assessment was elaborated for included investigations. Results: In total, 812 articles were identified, of which 8 were included in the analysis. Steam autoclave was the most widely used form of resterilization. Not a single protocol, however, was able to achieve 100% virgin surface of the healing abutments. Conclusion: Although reuse of dental implant healing abutments is a cost-effective measure in dental practice, thorough surface decontamination followed by resterilization is highly recommended before reuse. Knowledge Transfer Statement: With consideration of cost and patient preference, results of this review would be useful in knowing various sterilization protocols for reusing healing abutments that could lead to more appropriate therapeutic decisions.

BackgroundIt is critical to develop a reliable and cost-effective prognostic tool for colorectal cancer (CRC) stratification and treatment optimization. Tumor–stroma ratio (TSR) may be a promising indicator of poor prognosis in CRC patients. As a result, we conducted a systematic review on the predictive value of TSR in CRC.MethodsThis study was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guideline. An electronic search was completed using commonly used databases PubMed, CENTRAL, Cochrane Central Register of Controlled Trials, and Google scholar till the last search up to May 30, 2021. STATA version 13 was used to analyze the data.ResultsA total of 13 studies [(12 for disease-free survival (DFS) and nine studies for overall survival (OS)] involving 4,857 patients met the inclusion criteria for the systematic review in the present study. In individuals with stage II CRC, stage III CRC, or mixed stage CRC, we observed a significantly higher pooled hazard ratio (HR) in those with a low TSR/greater stromal content (HR, 1.54; 95% CI: 1.20 to 1.88), (HR, 1.90; 95% CI: 1.35 to 2.45), and (HR, 1.70; 95% CI: 1.45 to 1.95), respectively, for predicting DFS. We found that a low TSR ratio had a statistically significant predictive relevance for stage II (HR, 1.43; 95% CI: 1.09 to 1.77) and mixed stages of CRC (HR, 1.65; 95% CI: 1.31 to 2.0) for outcome OS.ConclusionIn patients with CRC, low TSR was found to be a prognostic factor for a worse prognosis (DFS and OS).

Abstract Background Sexually transmitted infection (STI) rates are increasing in the US while funding for prevention and treatment programs has declined. Self-collection testing for STI detection in men may provide an acceptable, easy, rapid, and potentially cost-effective method for increasing diagnosis and treatment of STIs. The purpose of this study was to systematically review articles assessing self-collection of anal, oral, or genital tests among adult men for STI detection and/or human papillomavirus (HPV)-related dysplasia. Methods We searched for English-language articles involving self-collection tests for STI detection among men aged ≥ 18 years using the following databases: MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials. Three coders used a screening and data abstraction form to record each study’s design, participant demographics, intervention, and primary outcome. The self-collection devices, targeted micro-organisms, and self-collection acceptability measures were also recorded. All studies were double-coded to determine final inclusion in the review. Results Self-collection methods were highly sensitive and comparable to clinician-collection for detection of multiple STI pathogens but were of less adequate quality for anorectal cytology. Self-collection was highly acceptable. Conclusion Limitations of this systematic review include the fact that studies were small, heterogeneous, and used designs providing lower levels of evidence. Nevertheless, self-collection methods were shown to be a viable option for STI testing in adult men based on their high feasibility, acceptability, and validity. Implementation of self-collection procedures in STI testing venues should be performed to expand opportunities for STI detection and treatment. Disclosures All authors: No reported disclosures.

Objective We conducted a meta-analysis and systematic review to evaluate the effects of dexmedetomidine on the hemodynamics of patients undergoing hysterectomy. Methods We searched the Medline, Embase, and Cochrane Central Register of Controlled Trials databases for clinical randomized controlled trials (RCTs) that allowed direct or indirect comparisons of hemodynamic indicators. We also searched nine English-language databases up to April 2021 to identify relevant research. The Cochrane risk-of-bias tool for RCTs was applied to assess the methodological quality of the eligible studies. The meta-analysis was conducted using RevMan 5.4 software. Results Nine trials were included in this systematic review. The effect of dexmedetomidine on heart rate during surgery was significantly smaller than that of other sedatives. Intraoperative systolic and diastolic blood pressure and mean arterial pressure were more stable in the dexmedetomidine group compared with the control group. The postoperative modified Observer’s Assessment of Alertness Score was also better in the dexmedetomidine compared with the control group. Conclusions Dexmedetomidine increases hemodynamic stability in patients undergoing hysterectomy, reduces the cardiovascular stress response during surgery, and effectively prevents postoperative adverse reactions, with good safety.

The present systematic review evaluates the safety of placing dental implants in patients with a history of antiresorptive or antiangiogenic drug therapy. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. PubMed, Cochrane Central Register of Controlled Trials, Scopus, Web of Science, and OpenGrey databases were used to search for clinical studies (English only) to July 16, 2019. Study quality was assessed regarding randomization, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases using a modified Newcastle-Ottawa scale and the Joanna Briggs Institute critical appraisal checklist for case series. A broad search strategy resulted in the identification of 7542 studies. There were 28 studies reporting on bisphosphonates (5 cohort, 6 case control, and 17 case series) and one study reporting on denosumab (case series) that met the inclusion criteria and were included in the qualitative synthesis. The quality assessment revealed an overall moderate quality of evidence among the studies. Results demonstrated that patients with a history of bisphosphonate treatment for osteoporosis are not at increased risk of implant failure in terms of osseointegration. However, all patients with a history of bisphosphonate treatment, whether taken orally for osteoporosis or intravenously for malignancy, appear to be at risk of ‘implant surgery-triggered’ MRONJ. In contrast, the risk of MRONJ in patients treated with denosumab for osteoporosis was found to be negligible. In conclusion, general and specialist dentists should exercise caution when planning dental implant therapy in patients with a history of bisphosphonate and denosumab drug therapy. Importantly, all patients with a history of bisphosphonates are at risk of MRONJ, necessitating this to be included in the informed consent obtained prior to implant placement. The James Cook University College of Medicine and Dentistry Honours program and the Australian Dental Research Foundation Colin Cormie Grant were the primary sources of funding for this systematic review.

Background Glenohumeral joint instability is associated with structural deficits and/or alterations in sensory and motor processing; however, a proportion of patients with glenohumeral joint instability fail to respond to surgical and rehabilitative measures. This systematic review aimed to establish if functional cortical changes occur in patients with glenohumeral joint instability. Methods AMED, CINAHL, Cochrane Central Register of Controlled Trials, Embase, Medline, PEDro, Pubmed, PsychINFO and Scopus were searched from inception to 17 March 2021. Randomised controlled trials and non-randomised trials were included and quality was appraised using the Downs and Black tool. Results One thousand two hundred seventy-nine records were identified of which five were included in the review. All studies showed altered cortical function when comparing instability patients with healthy controls and included areas associated with higher cortical functions. Discussion The findings of this systematic review offer some insight as to why interventions addressing peripheral pathoanatomical factors in patients with glenohumeral joint instability may fail in some cases due to functional cortical changes. However, data are of moderate to high risk of bias. Further high-quality research is required to ascertain the degree of functional cortical changes associated with the type and duration of glenohumeral joint instability.

PurposeOpioids are recommended for moderate-to-severe cancer pain; however, in patients with cancer, impaired hepatic function can affect opioid metabolism. The aim of this systematic review was to evaluate the evidence for the use of opioids in patients with cancer with hepatic impairment.MethodsA systematic review was conducted and the following databases searched: AMED (−2021), MEDLINE (−2021), EMBASECLASSIC + EMBASE (−2021) and Cochrane Central Register of Controlled Trials (−2021). Eligible studies met the following criteria: patients with cancer-related pain, taking an opioid (as defined by the WHO Guidelines for the pharmacological and radiotherapeutic management of cancer pain in adults and adolescents); >18 years of age; patients with hepatic impairment defined using recognised or study-defined definitions; clinical outcome hepatic impairment related; and primary studies. All eligible studies were appraised using the Grading of Recommendations Assessment, Development and Evaluation system.ResultsThree studies (n=95) were eligible but heterogeneity meant meta-analysis was not possible. Each individual study focused on only one each of oxycodone±hydrocotarnine, oxycodone/naloxone and morphine. No recommendations could be formulated on the preferred opioid in patients with hepatic impairment.ConclusionsMorphine is the preferred opioid in hepatic impairment owing to clinical experience and pharmacokinetics. This review, however, found little clinical evidence to support this. Dose adjustments of morphine and the oxycodone formulations reviewed remain necessary in the absence of quality evidence. Overall, the quality of existing evidence on opioid treatments in cancer pain and hepatic impairment is low and there remains a need for high-quality clinical studies examining this.

Objective: The objective of this review is to reveal the quality of published data and the effect size of DPFs compared to rigid fixation in lumbar spine. Summary of background data: since 2002, several dynamic pedicle fixation (DPF) systems have been developed with the aim to stabilize the spine without the undesirable effects of rigid lumbar spine fixation. Nearly ten years later, there are several studies on these dynamic systems. Methods: A systematic review was done in MEDLINE/PubMED, Embase, Cochrane Central Register of Randomized Trials and Google Scholar to assess the quality of published literature and the available studied outcomes in randomized controlled trials of DPF. Results: Only three papers described randomized trials studying DPF. One of them focused on protection of adjacent level disease provided by DPF. Conclusion: It was not possible to reveal any evidence for benefits using DPF compared to rigid fixation in surgery for lumbar spine.

Background The decline in the uptake of routine childhood vaccinations has resulted in outbreaks of vaccine-preventable diseases. Vaccination apps can be used as a tool to promote immunization through the provision of reminders, dissemination of information, peer support, and feedback. Objective The aim of this review is to systematically review the evidence on the use of apps to support childhood vaccination uptake, information storage, and record sharing. Methods We will identify relevant papers by searching the following electronic databases: PubMed, Embase by Ovid, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, and Education Resources Information Center (ERIC). We will review the reference lists of those studies that we include to identify relevant additional papers not initially identified using our search strategy. In addition to the use of electronic databases, we will search for grey literature on the topic. The search strategy will include only terms relating to or describing the intervention, which is app use. As almost all titles and abstracts are in English, 100% of these will be reviewed, but retrieval will be confined to papers written in the English language. We will record the search outcome on a specifically designed record sheet. Two reviewers will select observational and intervention studies, appraise the quality of the studies, and extract the relevant data. All studies will involve the use of apps relating to child vaccinations. The primary outcome is the uptake of vaccinations. Secondary outcomes are as follows: (1) use of app for sharing of information and providing vaccination reminders and (2) use of app for storage of vaccination information; knowledge and decision making by parents regarding vaccination (ie, risks and benefits of vaccination); costs and cost-effectiveness of vaccination apps; use of the app and measures of usability (eg, usefulness, acceptability, and experiences of different users: parents and health care professionals); use of technical standards for development of the app; and adverse events (eg, data leaks and misinformation). We will exclude studies that do not study an app. We anticipate a limited scope for meta-analysis and will provide a narrative overview of findings and tabular summaries of extracted data. Results This project was funded by the Sir David Cooksey Fellowship in Healthcare Translation at the University of Oxford, Oxford, United Kingdom. We will submit the full systematic review for publication in the Journal of Medical Internet Research. Conclusions This review will follow, where possible, the Cochrane Collaboration and the Centre for Review and Dissemination methodologies for conducting systematic reviews. We will report our findings based on guidelines from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The review results will be used to inform the development of a vaccination app. International Registered Report Identifier (IRRID) PRR1-10.2196/16929

Background: Azithromycin (AZM) has been widely used in the management of Covid-19. However, the evidence on its actual effects remains disperse and difficult to apply in clinical settings. This systematic review and metanalysis summarizes the studies on the beneficial and adverse effect of AZM in patients with Covid-19. Methods: The PRISMA 2020 statement criteria were followed. Randomized controlled trials (RCTs) and observational studies comparing clinical outcomes of patients treated, and not treated, with AZM, indexed until the 5th of July 2021, were searched in PubMed, Embase, The Web of Science, Scopus, The Cochrane Central Register of Controlled Trials, and MedRXivs. We used Random-effects models to estimate pooled effect size from aggregate data. Results: The initial search produced 4950 results. Finally, 16 studies, five RCTs and 11 with an observational design, with a total of 22984 patients, were included. The metanalysis showed no difference in mortality for those treated, or not, with AZM, OR: 0.95 (0.79-1.13). There was also no significant difference for those treated, and not, with AZM in need for hospital admission or time to admission from ambulatory settings, clinical severity, need for intensive care, or adverse effects. Conclusions: These results presented in this review do not support the use of AZM in the management of Covid-19. They also show that any harm caused to the patient who received it is unlikely. Future research on treatment for patients with Covid-19 may need to focus on other drugs

At Home

Hospital at home is a service that provides active treatment by healthcare professionals in the patient’s home for a condition that otherwise would require acute hospital in-patient care. However, the clinical benefit of this intervention and its effect on health costs are not established. This Cochrane systematic review aimed to assess the effectiveness and costs of managing patients with hospital at home compared with inpatient hospital care. A systematic review of the literature was carried out by searching the following databases to 9 January 2017: Cochrane Effective Practice and Organization of Care Group (EPOC) register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, EconLit and clinical trials registries. Thirty-two randomized trials (2 of which unpublished), including 4746 patients, were included. The present review provides insufficient objective evidence of economic benefit (through a reduction in hospital length of stay) or improved health outcomes.
