Abstract Objective: The present study explains the success and failure of dental implant diameter on the efficiency of fatigue by conducting a systematic review analysis. Methods: An extensive literature search was conducted to carry out systematic review using different scholarly platforms and libraries. A total of 12 studies published within the past 20-year time (1999-2019) were included following the inclusion and exclusion criteria based on the PRISMA guidelines. Additionally, the study outcomes were evaluated to determine their perceptions regarding the role of dental implant diameter in influencing the implant’s fatigue performance. Results: The implant diameter can be categorized into wide diameter (5-6 mm), regular diameter (3.75-4 mm), and small/narrow diameter (3-3.4 mm). The narrow diameter implants are indicated through thin alveolar ridges and mesiodistal spaces (less than 7 mm). The implants with narrow diameter would offer greater risk of fatigue failure for clinical situations with significant functional loading. No significant differences were found either in success or failure of dental implant diameter on fatigue efficiency after 1-year and 3-year follow-up. Conclusion: The technical complication of dental implant include abutment screw loosening or fracture, abutment and superstructure fracture, and implant body fracture. The study has study has mainly focused on the impact of dental implant diameter on the efficiency of fatigue and reviewed a significant impact of dental implant diameter on the fatigue efficiency.

INTRODUCTION: Sit-to-stand and stand-to-sit are two of the most mechanically demanding activities undertaken in daily life and which are usually impaired in stroke subjects. OBJECTIVES: To determine the distinguishing characteristics in musculoskeletal biomechanical outcomes of the sit-to-stand and stand-to-sit activities with stroke subjects, with an emphasis on the clinical management of stroke disabilities, in a systematic review. MATERIAL AND METHODS: An extensive literature search was performed with the MEDLINE, CINAHL, EMBASE, PEDro, LILACS, and SciELO databases, followed by a manual search, to select studies on musculoskeletal biomechanical outcomes in both activities with stroke subjects, without language restrictions, and published until December/2007. RESULTS: Out of the 432 studies, only 11 reported biomechanical outcomes of both activities and none reached the total score on the selected quality parameters. The majority of the experimental studies which compared groups did not achieve acceptable scores on their methodological quality (PEDRo). The investigated conditions and interventions were also restricted. Only one study compared biomechanical outcomes between the activities, but only evaluated the time spent to perform them. Few musculoskeletal biomechanical outcomes have been investigated, being weight bearing on the lower limbs and duration of the activities the most investigated. CONCLUSION: There is little information regarding musculoskeletal biomechanical outcomes during these activities with stroke subjects and no definite conclusions can be drawn regarding the particularities of these outcomes on their performance with stroke survivors.

The Impact

In order to determine if dentist anesthesiologists (DAs) actively contribute to research in the field of anesthesiology, and thus contribute new knowledge to the field, an extensive literature search was accomplished. DAs make up only 1.5% of dentists who actively contribute to anesthesia research but account for 10% of publications. To determine if the impact of DA research was similar to the American Dental Association (ADA) recognized specialties, h-indices of noted researchers in other specialties were compared to the h-indices of noted DA researchers. The results show that the impact of top DA researchers in dental anesthesiology is similar to the impact of top dental specialty researchers, despite lack of academic departments in dental schools where a large percentage of dental research is completed. Dentist anesthesiologists actively contribute to the research in anesthesiology for dentistry and thus, actively contribute to new knowledge in the field.

Tissue Sparing

Study Design: Literature review. Objectives: Posterior cervical interfacet cages are an alternative to lateral mass fixation in patients undergoing cervical spine surgery. Recently, a percutaneous, tissue-sparing system for interfacet cage placement has been developed, however, there is limited clinical evidence supporting its widespread use. The aim was to review studies published on this system for patient reported outcomes, radiographic outcomes, intraoperative outcomes, and complications. Methods: Four electronic databases (PubMed, EMBASE, Scopus, and MEDLINE) were queried for original published studies that evaluated the percutaneous, tissue-sparing technique for posterior cervical fusion with interfacet cage placement. All studies reporting on open techniques and purely biomechanical studies were excluded. Results: The extensive literature search returned 7852 studies. After systematic review, a total of 7 studies met inclusion criteria. Studies were independently classified as retrospective or prospective cohort studies and each assessed by the GRADE criteria. Patient reported outcomes, radiographic outcomes, intraoperative outcomes, and complications were extracted from each study and presented. Conclusions: Tissue-sparing, posterior cervical fusion with interfacet cages may be considered a safe and effective surgical intervention in patients failing conservative management for cervical spondylotic disease. However, the quality of evidence in the literature is lacking, and controlled, comparative studies are needed for definitive assessment.

And Performance

Shielding has been recommended as an effective tool against radiation exposure. Several studies have published on the availability and use of shielding tools in diagnostic X-ray centers across the country and contradictory results been reported. Therefore, the aim of this systematic review was to find out the status of radiation protection in term of availability and use of shielding tools in diagnostic X-ray centers in Iran. An extensive literature search was conducted in the PubMed/Medline, Embase, ISI, Cochrane Library, SID, Magiran, IranMedex, Irandoc and Google-Scholar search engine. We also manually searched the reference lists of the relevant studies. Two authors independently assessed the eligibility of all studies and extracted data. Thirty-seven studies published from 1998 to 2019 were included in this systematic review. In all, 1089 diagnostic X-ray centers, 4439 radiographs and performance of 1472 radiographers were covered in these studies. The availability of lead apron, gonad shield and thyroid collar were ranged from 7 to 95.5%, 26.6 to 94% and 7 to 94%, respectively. Moreover, their usage was ranged from 0 to 85.5%, 0 to 35% and 0 to 38.4%, respectively. In addition, lens shield was discussed in one study with availability of 0%. During 1998 to 2019, the status of shielding had not improved across the country. Therefore adherence to the safety guideline as far as possible is required to protection patients from undue exposure to radiation.

The Impact

Purpose – The purpose of this paper is to explore the research which has examined the link between autism spectrum disorders (ASDs) and offending behaviour and the impact of prison on individuals with ASDs. Studies suggest that inmates with ASDs may be at an increased risk of bullying, confrontations, exploitation, anxiety and social isolation as a result of their ASD traits such as obsessions, social naivety and impaired empathy. Design/methodology/approach – An extensive review of the literature. Findings – The review identifies a modest amount of studies (n=4) which have explored the experience of individuals with ASD in prison and highlights that inmates with ASDs face a multitude of problems when they enter prison. Despite an extensive literature search only one study was identified which investigated the knowledge and understanding of ASDs amongst prison staff. Research limitations/implications – Further research is urgently needed to consider the specific problems faced by inmates with ASD, to identify how to make the prison environment safer and more supportive for inmates with ASD and how to reduce the likelihood of re-offending. Practical implications – This review highlights that, to date, there has been relatively little to guide service design in order to develop support services for individuals with ASD in prison. There has been a scarcity of studies investigating the effectiveness of various treatment models to target offending behaviour in individuals with ASD. Originality/value – This paper fulfils an identified need to study and identify the specific problems faced by inmates with ASD and to identify changes which are required to provide an environment in prison which is safer and more supportive.

Poor Outcomes

Abstract Introduction We aimed to determine if patients with CHD are at a higher risk of poor outcomes if they have COVID-19, compared to those without CHD. Method A systematic review was executed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. To identify articles related to COVID-19 and CHD, an extensive literature search was performed on EMBASE, Medline, Scopus and Global Health databases using keywords and MeSH terms. Results 12 articles met the inclusion criteria and were included for analysis in this systematic review. Two themes were identified for data extraction: [1] evidence supporting higher risks in CHD patients and [2] evidence against higher risks in CHD patients. After combining the data, there were 99 patients with CHDs out of which 12 required admission to ICU. Conclusions This systematic review suggests that CHD may increase the risk of poor outcomes for those with COVID-19, but also highlights the necessity for more research with larger sample sizes in order to make a more justified conclusion, as the majority of papers that were analysed were case series and case reports. Future research should aim to quantify the risks if possible while accounting for various confounding factors such as age and treatment history.
