Abstract Objectives Individuals with cystic fibrosis (CF) are at high risk for malnutrition and poor growth. New drugs that modulate CF transmembrane receptor (CFTR) function are available, although their effects on anthropometric parameters are not clear. This systematic review aimed to determine if various CFTR modulator therapies affect weight and growth parameters in individuals with CF. Methods A literature search was conducted using MEDLINE, CINAHL and Embase databases for peer-reviewed, randomized controlled trials (RCT) published from January 2002 to May 2018 that examined the effect of CFTR modulation therapy on weight and growth parameters in children and adults with CF. Articles were screened for relevance, data was extracted and summarized, and risk of bias was assessed to determine the quality of evidence. Results A total of 612 original articles were identified, and 13 articles representing 10 RCTs were included in qualitative synthesis and three were included in quantitative synthesis. All but one RCT demonstrated low risk of bias. The targeted class of CFTR mutation varied by RCT. Studies indicated that, in children and adults with CF with class III mutations, ivacaftor treatment alone increased weight and BMI (4 RCTs), but it did not influence growth in individuals with class II (1 RCT) or class IV mutations (1 RCT). Treatment with ivacaftor + lumacaftor in adults homozygous for the F508del CFTR mutation (class II) increased BMI following 24 weeks of treatment (2 RCTs), but there was no effect in adults heterozygous for the mutation treated for 8 weeks (1 RCT). Treatment with lumacaftor + tezacaftor in individuals ages 12–20 years with class II mutations did not change growth parameters (1 RCT). Conclusions Effects of CFTR modulators on increasing weight and growth in individuals with CF are likely dependent on the therapy formulation (single vs combination therapy) and the targeted CFTR mutation. Whereas ivacaftor alone increases weight and growth parameters in individuals with class III mutations, ivacaftor + lumacaftor is more effective at increasing BMI in adults homozygous for the class II F508del CFTR mutation. Additional studies are needed to determine effects of other CFTR modulator drugs on growth parameters in individuals with varying CFTR mutations.

Background: This study is a systematic literature review aiming at identifying the variation of the average nasolabial angle (NLA) in various orthodontic situations. The NLA is one of the key factors to be studied in an orthodontic diagnosis for the aesthetics of the nose and facial profile. Methods: Out of 3118 articles resulting from four search engines (PubMed, Cochrane Library, Turning Research Into Practice (TRIP) and SciELO), the final study allowed the analysis and comparison of only 26 studies. These included studies have considered the NLA in the following cases: teeth extraction, class II malocclusion, class III malocclusion, rapid palatal expansion (RPE), orthognathic surgery, and non-surgical rhinoplasty with a hyaluronic acid filler. Results: The results indicate that teeth extraction and the use of hyaluronic acid fillers significantly affect the NLA. Conclusions: This systematic review shows that a statistically significant change in NLA values occurs in: extractive treatments of all four of the first or second premolars in class I patients; in class II patients with upper maxillary protrusion; in patients with maxillary biprotrusion, except for cases of severe crowding; and in patients undergoing non-surgical rhinoplasty with a hyaluronic acid filler.

BackgroundSpecific mechanisms of injury are stated in pre-hospital triage tools to identify suspected cases of major trauma. Falls down stairs are common presentations in UK emergency departments, yet are frequently overlooked as a causative mechanism of major trauma. No prior systematic review has examined this association.MethodsSeven internationally recognised literature databases and seven grey literature databases were screened utilising a common search strategy from inception until 31 December 2019. Abstracts were screened for relevance by a single reviewer. Full texts were screened and subsequently extracted by 3 separate reviewers against strict inclusion/exclusion criteria. A risk of bias assessment based on GRADE recommendations was performed. In the absence of study heterogeneity, a narrative synthesis was planned. The reporting of this systematic review followed PRISMA 2009 statement guidelines.Results5240 articles were identified from database searching, 89 articles had their full texts assessed for eligibility and 6 articles were included for qualitative synthesis. All studies were retrospective in nature and originated from more economically developed countries. 7431 patients who fell down stairs were analysed, of which, 707 (9.5%) met major trauma definitions. Falls down stairs resulted in a significantly increased risk of serious injury compared to other fall mechanisms (OR: 1.621, 95% CI: 1.381 – 1.902, p<0.0005). Analysis of confounding factors demonstrated age (OR: 2.59, 95% CI: 1.57 – 4.28, p<0.001) and alcohol intoxication (OR: 2.6, 95% CI: 1.4 – 4.7, p=0.001) to be significantly associated with major trauma. Risk of bias was moderate to high across all 6 studies.ConclusionThis systematic review highlighted the paucity of literature surrounding the incidence of major trauma following falls down stairs.A retrospective cohort study is currently being undertaken to analyse the risk of major trauma following falls down stairs. On completion, the results will be incorporated with the results of this systematic review.

AimsMany sarcoidosis patients experience a reduction in health-related quality of life (HRQoL) and a majority of patients report fatigue. Historically, drug trials in sarcoidosis have focused on changes in chest radiographs, lung function parameters and biomarkers, while HRQoL and fatigue have not been the main outcomes examined. We performed a systematic review of the literature to evaluate the existing evidence on the effects of pharmacological interventions on HRQoL and fatigue outcomes.MethodsThe systematic search was performed in Medline and Embase and yielded 15 records covering seven randomised controlled trials and seven single-arm open label studies, which were included in a qualitative synthesis (the results of one study were included in two publications). 12 studies evaluated immunosuppressive and/or immunomodulatory therapies and two studies evaluated stimulants.ResultsNine out of the 14 studies observed positive treatment effects from the interventions on HRQoL and/or fatigue, exceeding the minimal important difference. The risk of bias was generally high with only three studies rated as having a low risk of bias. The results suggest a potential for improvement in HRQoL and/or fatigue in patients with active disease who are either untreated or treated but not yet fully stabilised or therapy refractory.ConclusionMore randomised, double-blind and placebo-controlled trials are needed to expand the evidence base on these important outcome parameters.

Composite dust generation is most likely a continuous and daily procedure in dental practice settings. The aim of this systematic review was to identify, compile and evaluate existing evidence on interventions and composite material properties related to the production of aerosolized dust during routine dental procedures. Seven electronic databases were searched, with no limits, supplemented by a manual search, on 27 April 2020 for published and unpublished research. Eligibility criteria comprised of studies of any design, describing composite dust production related to the implementation of any procedure in dental practice. Study selection, data extraction and risk of bias (RoB) assessment was undertaken independently either in duplicate, or confirmed by a second reviewer. Random effects meta-analyses of standardized mean differences (SMD) with associated 95% confidence intervals (CIs) were employed where applicable. A total of 375 articles were initially identified, resulting in 13 articles being included in the qualitative synthesis, of which 5 contributed to meta-analyses overall. Risk of bias recordings ranged between low and high, pertaining to unclear/raising some concerns, in most cases. All types of composites, irrespective of the filler particles, released significant amounts of nano-sized particles after being ground, with potentially disruptive respiratory effects. Evidence supported increased % distribution of particles < 100 nm for nanocomposite Filtek Supreme XTE compared to both conventional hybrid Z100MP (SMD: 1.96, 95% CI: 0.85, 3.07; p-value; 0.001) and nano- hybrid Tetric EvoCeram (SMD: 1.62, 95% CI: 0.56, 2.68; p-value: 0.003). For cytotoxicity considerations of generated aerosolized particles, both nanocomposites Filtek Supreme XTE and nanohybrid GradiO revealed negative effects on bronchial epithelial cell viability, as represented by % formazan reduction at 330–400 μg/mL for 24 hours, with no recorded differences between them (SMD: 0.19; 95% CI: −0.17, 0.55; p-value: 0.30). Effective and more rigorous management of dental procedures potentially liable to the generation of considerable amounts of aerosolized composite dust should be prioritized in contemporary dental practice. In essence, protective measures for the clinician and the practices’ personnel should also be systematically promoted and additional interventions may be considered in view of the existing evidence.

ABSTRACT Objective: To evaluate the changes in apical base sagittal relationship in Class II treatment with and without premolar extractions. Materials and Methods: Controlled studies evaluating ANB angle changes after Class II Division 1 malocclusion treatment with or without premolar extractions were considered. Electronic databases (PubMed, Embase, Web of Science, Scopus, The Cochrane Library, Lilacs, and Google Scholar) without limitations regarding publication year or language were searched. Risk of bias was assessed with Risk Of Bias in Non-randomized Studies—of Interventions tool of the Cochrane Collaboration. Mean difference (MD) and 95% confidence interval (CI) were calculated from the random-effects meta-analysis. Subgroup and sensitivity analyses were also performed. Results: Twenty-five studies satisfied the inclusion criteria and were included in the qualitative synthesis. Eleven nonextraction and only one extraction Class II treatment studies presented untreated Class II control group. Therefore, meta-analysis was performed only for the nonextraction protocol. In treated Class II nonextraction patients, the average of the various effects was a reduction in the ANB angle of 1.56° (95% CI: 1.03, 2.09, P &lt; .001) compared with untreated Class II subjects. Class II malocclusions treated with two maxillary-premolar extractions and four-premolar extractions produced estimated mean reductions in ANB of −1.88° and −2.55°, respectively. However, there is a lack of low-risk-of-bias studies. Conclusions: According to the existing low quality evidence, the apical base sagittal relationship in nonextraction, two-maxillary and four-premolar extractions Class II treatments decreases −1.56°, 1.88° and 2.55°, respectively. Further studies are necessary to obtain more robust information.

Periodontal Attachment

Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and has been considered a risk factor for periodontal disease. The aim of this systematic review and meta-analysis was to verify the scientific evidence for the association of periodontal attachment loss with low BMD in postmenopausal women. A systematic search of the literature was performed in databases until August 2016, in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Eligibility criteria included studies that compared clinical attachment loss (CAL) between postmenopausal women with low and normal BMD. Studies using similar methodology, with lower and higher risk of bias, were pooled into 3 different meta-analyses to compare CAL among women with normal BMD, osteoporosis, and osteopenia. In the first meta-analysis, mean CAL was compared among groups. In the other 2 meta-analyses, the mean percentages of sites with CAL ≥4 mm and ≥6 mm were respectively compared among groups. From 792 unique citations, 26 articles were selected for the qualitative synthesis. Eleven of the studies were appraised as presenting low risk of bias, and the association between low BMD and CAL was observed in 10 of these studies. Thirteen cross-sectional articles were included in the meta-analysis for osteoporosis and 9 in the osteopenia analysis. Women with low BMD presented greater mean CAL than those with normal BMD (osteoporosis = 0.34 mm [95% confidence interval (CI), 0.20–0.49], P < 0.001; osteopenia = 0.07 mm [95% CI, 0.01–0.13], P = 0.02). Only studies with lower risk of bias were available for the analysis of CAL severity. Women with low BMD presented more severe attachment loss, represented as mean percentage of sites with CAL ≥4 mm (osteoporosis = 3.04 [95% CI, 1.23–4.85], P = 0.001; osteopenia = 1.74 [95% CI, 0.36–3.12], P = 0.01) and CAL ≥6 mm (osteoporosis = 5.07 [95% CI, 2.74–7.40], P < 0.001). This systematic review and meta-analysis indicates that postmenopausal women with osteoporosis or osteopenia may exhibit greater CAL compared with women with normal BMD.

In differentiated thyroid carcinoma refractory to radioactive iodine (CDT-RTI), chemotherapy has been considered for decades to be the only systemic therapy with palliative purpose. Phase II studies assessing the efficacy of different chemotherapy outlines have been published. Nevertheless, phase III studies in these tumours have not been performed. Our objective is to evaluate the effectiveness of chemotherapy in patients with CDT-RTI by a systematic review of published studies. Systematic research of the literature in Medline and Embase databases (among others) was carried out. The full texts of selected references were analysed by two independent reviewers and then assessed for risk of bias in each study. We also extracted data using specifically designed questionnaires. Later, a qualitative synthesis of results was performed and pooled data were calculated. We found that 16 studies with 473 patients published in the last 40 years were included out of 509 identified references in databases. Thirteen studies (176 patients) included data on response to treatment and histology. Four studies included 70 patients only with well-differentiated non-medullary tumours. Response rate (RR) was 22.1% (0–57%) for 13 studies, 25% for the 176 patients and 27.1% for the 70 patients, with 2.5, 3.4 and 2.8% complete responses respectively. Survival times could not be assessed or pooled due to the lack of data and heterogeneity of the studies, and was determined to have a high risk of bias. Although it has not been possible to find solid evidence about the efficacy of chemotherapy, the results shown indicate that it may have some effectiveness, although this should be proven with well-designed studies using modern drugs.

Safety Considerations

Use of thermoplastic material in orthodontics, either as aligner or as retainer appliances, is common practice and is likely to increase in the years to come. However, no systematic assessment on safety considerations of these adjuncts has been implemented up to date. The aim of this systematic review was to collectively appraise the existing evidence from both clinical and laboratory studies, on whether these appliances are associated with any estrogenic/cytotoxic effects or bisphenol-A (BPA) and monomer leaching. Eight electronic databases were searched with no limits in December 22, 2019, for published and unpublished research. Eligibility criteria comprised of studies of any design, describing use of any type of thermoplastic aligner. Study selection, data extraction and risk of bias (RoB) assessment was done independently, either in duplicate or confirmed by a second reviewer. Random effects meta-analyses of weighted mean differences (WMD) with associated 95% Confidence Intervals (CIs) were planned. Quality of the evidence was evaluated with Grading of Recommendations Assessment, Development and Evaluation (GRADE). A total of 58 articles were initially identified, while 5 were included in qualitative synthesis and 2 of those contributed to the quantitative syntheses. Four studies were in-vitro, while one was a randomized controlled trial; all assessed some type of orthodontic aligner or retainer, either as-received or retrieved. Risk of bias recordings ranged between unclear and high for all studies. Proliferation induction capacity of thermoplastic appliances’ eluents on MCF-7 cells failed to be confirmed compared to beta-estradiol (2 studies: 5% v/v, WMD: −182.08; 95% CI: −198.83, −165.33; p-value < 0.001; and 20% v/v, WMD: −184.53; 95% CI: −206.17, −162.88; p-value < 0.001). No cytotoxic activity was detected as well. In addition, although evidence from in-vitro studies was indicative of no traceable detection of BPA or other monomers, the findings from a single clinical trial were allied to increased levels of BPA in whole stimulated saliva, after up to 30 days of thermoplastic retainer usage, compared to standard Hawley retainer. The quality of the evidence overall was low to medium. Current data from in-vitro research are indicative of an absence of an estrogenic or cytotoxic effect of thermoplastic aligners or retainers. Regarding BPA or monomer release, evidence from clinical and laboratory studies appear inconsistent.

Purpose: A systematic review and meta-analysis were done to evaluate the effect of obesity in injury and mortality due to motor vehicle accidents. Materials & Methods: The systematic review consisted of 20 studies meeting the inclusion criteria. The meta-analysis was conducted on these studies to analyze obesity as a risk factor for specific injuries, as well as overall injury and mortality compared to non-obese patients. Results: The data revealed that obesity was associated with increased lower extremity injuries (odds ratio [OR] = 1.44, 95% confidence interval [CI] = 1.19-1.69, P ≤ 0.05), neck injuries (OR = 3.38, 95% CI = 1.58-5.19, P ≤ 0.05), and overall mortality (OR = 1.51, 95% CI = 1.40-1.61, P ≤ 0.05). When stratified for obesity class with class I as BMI >30.1-34.9, class II BMI 35-39.9, and class III BMI >40, only class II (OR = 1.20, 95% CI = 1.15-1.24, P ≤ 0.05) and class III (OR = 1.49, 95% CI = 1.30-1.68, P ≤ 0.05) were associated with increased mortality risk. No significant differences were seen with head, upper extremity, thoracic, abdominal, or pelvic injuries. Conclusion: Obesity is a risk factor in motor vehicle accidents for fatality and injury, specifically lower extremity and neck injuries.
