Canine Guided Occlusion

Choosing an adequate occlusion is challenging during the construction of artificial dentures, and critical for patient satisfaction. However, there is no conclusive evidence to support which occlusal design is more appropriate. The aim of this systematic review was to evaluate canine-guided occlusion in comparison to other occlusal schemes in removable complete denture wearers. The review was conducted according to the Preferred Reported Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. An extensive search was carried out on (PubMed (National Library of Medicine)), Scopus (Elsevier), Cochrane collaboration (Wiley), Science Direct (Elsevier) and Europe PMC (European Bioinformatics Institute). English and non-English studies were identified using keywords on canine-guided occlusion, denture occlusion, dental occlusion and artificial occlusal schemes. Out of 1759 articles searched, 18 were selected based on the inclusion criteria. The included studies were interpreted for the descriptive analysis for the calculation of occlusal schemes, occlusion assessment parameters, the outcome of the occlusal schemes and types of removable prosthesis used. The systematic analysis of occlusal schemes revealed that canine-guided occlusion is viable compared with other occlusal designs in terms of patient satisfaction, mastication, retention, esthetics, phonetics, oral-health-related quality of life and muscle activity. The type of occlusal scheme influences the complete denture patient’s’ masticatory efficiency, satisfaction, retention, phonetics and esthetics. Nevertheless, physical, physiological, mechanical and psychological factors play a vital role in the success of removable complete dentures. The canine-guided occlusal scheme is preferred because of its simplicity, less time consumption, good masticatory performance, ease of fabrication and modification into bilateral balanced occlusion if required. Further studies are required to reduce the controversies related to jaw relations, gnathology and occlusal schemes in complete dentures.

Core Materials

Various material properties are involved in the success of endodontically treated restorations. At present, restorative composites are commonly employed as core build-up materials. This study aimed to systematically review the literature to assess the effect of using composite core materials on the in vitro fracture of endodontically treated teeth. Two different reviewers screened the literature, up to June 2021, in five distinct electronic databases: PubMed (MedLine), Scopus, Scielo, ISI Web of Science, and EMBASE. Only in vitro studies reporting the effect of the use of composite core materials on the fracture resistance of endodontically treated teeth were included. A meta-analysis was carried out using a software program (Review Manager v5.4.1; The Cochrane Collaboration, Copenhagen, Denmark). The risk of bias in each study was assessed following the parameters of another systematic review. A total of 5016 relevant papers were retrieved from all databases. After assessing the title and abstract, five publications remained for qualitative analysis. From these, only three studies remained for meta-analysis. The fracture strength of endodontically treated teeth where a core build-up composite was used was statistically significantly higher than the control (p = 0.04). Most of the analyses showed a high heterogenicity. The in vitro evidence suggests that the composite core build-up with higher filler content tended to improve the fracture resistance of the endodontically treated teeth, in comparison with conventional composite resins. This research received no external funding. Considering that this systematic review was only carried out on in vitro papers, registration was not performed. Furthermore, there were no identified clinical studies assessing core build-up materials; therefore, more well-designed research on these materials is needed.

Abstract This updated systematic review assesses the effects of pharmacological interventions for drug-using offenders. Methods Systematic review protocols and conventions of the Cochrane Collaboration were followed to identify eligible studies. Studies were pooled in a meta-analysis to assess the impact of pharmacological interventions on drug use and criminal activity. An economic appraisal was conducted. Results The search strategies identified 22 studies containing 4372 participants. Meta-analyses revealed a small statistically significant mean difference favouring pharmacological interventions relative to psychological interventions in reducing drug use and criminal activity. When comparing the drugs to one another there were no significant differences between those included (methadone versus buprenorphine, naltrexone and cyclazocine). Conclusion Overall, the findings of this review suggest that methadone and naltrexone may have some impact on reducing drug use and reincarceration. Individual pharmacological drugs had differing (generally non-significant) effects. One study identified serious adverse events. Three studies reported cost and consequences information sufficient to conduct a full economic analysis but this was not comprehensive enough to be able to make judgements across all treatment options. Full economic analyses should be encouraged. The study findings were limited mainly to male adult offenders.

Introduction: Hypertension is a chronic condition that might lead to renal and cardiovascular diseases. The previous trials examining the effect of cinnamon supplementation on blood pressure have led to conflicting results. The present systematic review aimed to summarize the effect of cinnamon supplementation on blood pressure using a meta-analysis of published randomized controlled clinical trials. Methods: To identify the eligible articles, MEDLINE, SCOPUS, ISI Web of Science, and Google Scholar were searched from inception until September 2019 for relevant articles. The risk of bias assessment was performed using the Cochrane collaboration tool. A Random-effects model was applied to calculate the summary effects. Results: Totally, 11 trials with 686 participants were included in this systematic review and meta-analysis. The dose of cinnamon supplement consumption varied from 500 to 10000 mg/d. The meta-analysis revealed that cinnamon supplementation significantly decreases systolic blood pressure (SBP) [WMD (weighted mean difference)= -5.72 mmHg, 95% confidence interval (CI): -8.63 to -2.80; P<0.001, I2= 81.1)] and diastolic blood pressure (DBP) (WMD= -4.06 mmHg, 95% CI: -6.68 to -1.44; P= 0.002, I2 = 88.6). Subgroup analysis suggested no significant reduction of DBP in subjects with diabetes (WMD= -2.015 mmHg, 95% CI: -4.55 to 0.52; P= 0.12, I2 = 72.3) and prediabetes or metabolic syndrome (WMD= -4.8 mmHg, 95% CI: -10.06 to 0.44; P= 0.073, I2= 92.5). Conclusions: Cinnamon supplementation could be beneficial in lowering SBP and DBP in adults. Further studies with different doses are recommended to confirm the present findings.

Coronaviruses have been responsible for major epidemic crises in 2003 with SARS-CoV-1, in 2012 with MERS-CoV and in 2019 with SARS-CoV-2 (COVID-19), causing serious atypical pneumonia in humans. We intend, with this systematic analysis and meta-analysis, to clarify the prevalence of the various strains of coronavirus in different animal species. For this purpose, we carried out an electronic survey using Pubmed's Veterinary Science search tool to conduct a systematic assessment of published studies reporting the prevalence of different strains of coronavirus in different animal species between 2015 and 2020. We conducted different analysis to assess sensitivity, publication bias, and heterogeneity, using random and fixed effects. The final meta-analysis included 42 studies for systematic review and 29 in the meta-analysis. For the geographic regions with a prevalence greater than or equal to 0.20 (Forest plot overall; prevalence = 0.20, p < 0.01, Q = 10476.22 and I2 = 100%), the most commonly detected viruses were: enteric coronavirus (ECoV), pigeon-dominant coronavirus, (PdCoV), Avian coronavirus M41, Avian coronavirus C46, Avian coronavirus A99, Avian coronavirus JMK, MERS-CoV, Bovine coronavirus, Ro-BatCoV GCCDC1, Alphacoronavirus, Betacoronavirus, Deltacoronavirus, Gamacoronavirus and human coronaviruses (HCoVs). The wide presence of different strains of coronavirus in different animal species on all continents demonstrates the great biodiversity and ubiquity of these viruses. The most recent epidemiological crises caused by coronavirus demonstrates our unpreparedness to anticipate and mitigate emerging risks, as well as the need to implement new epidemiological surveillance programs for viruses. Combined with the need to create advanced training courses in One Health, this is paramount in order to ensure greater effectiveness in fighting the next pandemics.

There is paucity of evidence examining quality of life in children with HD and ARM prioritizing dimensions other than physical functioning, such as psychosocial functioning in a precise manner. As such, we have developed a systematic review protocol to narratively and quantitatively summarize the physical and psychosocial functioning of children affected by HD and ARM in hopes of addressing this limitation. The following databases were searched on Nov 5, 2019: MEDLINE including Epub Ahead of Print, In-Process &amp; Other Non-Indexed Citations (1946 to October 25, 2019) and Embase (1947 to 2019 October 25) and the CENTRAL Trials Registry of the Cochrane Collaboration (September 2019 Issue) using the Ovid interface. Searches were limited to English, to journal articles, and articles published since 2006. This review will identify retrospective and prospective cohort studies, case-control studies, case studies with greater than 5 participants, and randomized-control trials where the quality of life (i.e., physical and/or social functioning) of children aged 0-18 years with either anorectal malformations or Hirschprung’s disease is reported by children or parent proxies. Understanding the quality of life of children affected by HD and ARM after surgery will help clinical practitioners, specifically surgeons, create tailored and comprehensive protocols for managing these diseases while recognising the physical, social, and emotional toll they can inflict on children.

Background: The objective of this study is to analyze the efficacy of local bupivacaine irrigation after augmentation mammoplasty for the control of postoperative pain. Methods: A systematic review and meta-analysis was conducted including all randomized controlled trials (RCTs) that compared the irrigation of bupivacaine (±ketorolac) versus normal saline or no irrigation for pain control after breast augmentation. The primary outcome was postoperative pain measured by visual analog scale. The study protocol was established a priori according to the recommendations of the Cochrane Collaboration. A bibliographical search was conducted in September 2015 in the following Cochrane Library databases: CENTRAL, MEDLINE, EMBASE, and Scielo. The strategy used for the search was ((augmentation AND (“mammoplasty”[MeSH Terms] OR “mammoplasty”)) OR ((“breast”[MeSH Terms] OR “breast”) AND augmentation)) AND ((“pain, postoperative”[MeSH Terms])). Results: Four RCTs with a total of 264 participants were included. Two trials compared bupivacaine alone versus placebo (normal saline or no irrigation) and 3 trials compared bupivacaine plus ketorolac versus placebo. The combined irrigation of bupivacaine and ketorolac showed a clinically significant reduction of pain in the first postoperative hour and on postoperative day 5. The irrigation with bupivacaine compared with placebo significantly reduced pain assessed on postoperative day 4. Conclusion: The irrigation of bupivacaine with or without ketorolac was associated with a reduction of postoperative pain compared with control groups for the first 5 postoperative days. Due to the few number of trials included, these results should be correlated further clinically.

Objective Does the use of metformin have an influence on the outcomes of preeclampsia (PE)? Sources of Data The descriptors pregnancy, metformin, treatment, and preeclampsia associated with the Boolean operators AND and OR were found in the MEDLINE, LILACS, Embase and Cochrane databases. A flowchart with exclusion criteria and inclusion strategy using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, and eligibility criteria was used. Data were extracted regarding the type of study, the applied dosage, treatment time, segment, bias risks, and the Patient, Intervention, Comparison and Outcome (PICO) strategy to identify the quality of the study. Selection of Studies Total number of journals in the initial search (n = 824); exclusions from repeated articles on different search engines (n = 253); exclusions after reading the titles, when the title had no correlations with the proposed theme (n = 164); exclusions due to incompatibility with the criteria established in the methodological analysis (n = 185), exclusion of articles with lower correlation with the objective of the present study (n = 187); and final bibliographic selection (n = 35). Data Collection At first, a systematic review of the literature was performed. Subsequently, from the main selection, randomized and non-randomized trials with metformin that presented their results in absolute and relative numbers of PE outcomes were selected. The variables were treated statistically in the meta-analysis with the Review Manager software (RevMan), version 5.3. Copenhagen: Nordic Cochrane Centre, The Cochrane Collaboration. Denmark in the Hovedistaden region. Synthesis of Data The study showed that metmorfin presented greater preventive effects for pregnancy-induced hypertension and was less effective for PE. Conclusion Metformin may gain place in preventive treatments for PE, once the dosages, the gestational age, and treatment time are particularly evaluated. A methodological strategy with an improved perspective of innovative and/or carefully progressive dosages during pregnancy to avoid side effects and the possibility of maternal-fetal risks is suggested.
