Purpose: In adults, correction of such a jaw base relation is done by bilateral sagittal split osteotomy and mandibular advancement which often causes change in the cervicomental angle that might not be within the acceptable and aesthetic range. The objective of this systematic review was to evaluate the changes observed in cervicomental angle after mandibular advancement surgery. Data Sources: Based on the available data, we conducted an electronic database PubMed search, based on the search of published data from 1994 to 2017, six strategies were designed using two keywords, and four articles were shortlisted for systematic review. Study Eligibility Criteria: Studies that provide information on cervicomental angle changes after mandibular advancement surgery, published from 1994 to 2017. Results: The search yielded 168 articles, of which four were included based on the selection criteria. These articles described that the cervicomental angle observed after mandibular advancement surgery falls between 95° and 125°. Conclusion: Cervicomental angle decreases as the mandible is advanced to correct the jaw base Class II relation to Class I. Acceptable range is found to be between 95° and 125°. Implications: An esthetic look is the desire of every patient that reports to the clinics for an orthodontic correction. Surgical correction is an integral part of the treatment. While advancing the mandible, change is observed in the cervicomental angle. Knowing the acceptable range of this angle will help the orthodontist and the oral surgeon to plan the advancement accordingly.

Objective: To conduct a systematic review of rigorously evaluated treatments for infant colic. Methods. Online bibliographic databases were searched for the term “colic” in articles classified as clinical trials or randomized controlled trials and conducted in infants. Reference lists from review articles, meta-analyses, and the selected articles were also reviewed for potential studies. The abstracts or full-text articles of 57 relevant studies were examined, of which 22 met the selection criteria. The methodology and findings of all retrieved articles were critically evaluated. Data were extracted from each article regarding study methods, intervention studied, outcomes measured, and results. Results. Four of the interventions studied had data of adequate quality and statistically significant numbers needed to treat (NNT): hypoallergenic diet (NNT = 6), soy formula (NNT = 2), reduced stimulation (NNT = 2), and herbal tea (NNT = 3). Conclusions. There are some effective therapies for infant colic, but additional rigorous studies of existing and alternative therapies are needed.

Introduction: Many medical associations recommend nephron-sparing surgery (NSS) for tumours larger than 4 cm amenable to partial nephrectomy (PN). These recommendations are, however, mostly based on isolated reports. We systematically review the oncological outcomes of partial nephrectomy procedures performed for tumours larger than 4-cm.Methods: A PubMed search was carried out using keywords “partial nephrectomy” and “nephron sparing” for records dating back to 1995. In total, 2136 abstracts were analyzed; from these, 174 studies were scrutinized. We identified 32 manuscripts reporting size-specific cancer-specific survival rates for masses greater than 4 cm. From each of these studies, we recorded the number of PN, tumour diameter, follow-up duration, 5- and 10-year recurrence, overall and cancer-specific survival rates (OS, CSS). We also calculated weighted OS and CSS rates.Results: This systematic review includes 2445 patients with renal tumours larger than 4 cm who underwent PN: 1858 patients with tumours between 4 to 7 cm, 410 patients with tumours larger than 7 cm and 177 patients with tumours greater than 4 cm (exact size unknown). Our analysis revealed weighted 5-year CSS rates of 95.4%, 86.2% and 93.9% for tumours 4 to 7 cm, >7 cm, and all tumours >4 cm, respectively. The respective 5-year OS rates were 84.7%, 76.4%, and 84.7%.Conclusions: We found excellent 5-year CSS and OS rates for patients with tumours 4 to 7 cm treated with PN. These outcomes compare favourably to those reported in historical radical nephrectomy (RN) series for similarly sized tumours. Thus, PN is an acceptable and often preferred treatment for renal masses >4 cm which are amenable to nephron-sparing procedures.

AbstractBackgroundThe objective of this study was to evaluate the nature and extent of reproducible and transparent research practices in neurology research.MethodsThe NLM catalog was used to identify MEDLINE-indexed neurology journals. A PubMed search of these journals was conducted to retrieve publications over a 5-year period from 2014 to 2018. A random sample of publications was extracted. Two authors conducted data extraction in a blinded, duplicate fashion using a pilot-tested Google form. This form prompted data extractors to determine whether publications provided access to items such as study materials, raw data, analysis scripts, and protocols. In addition, we determined if the publication was included in a replication study or systematic review, was preregistered, had a conflict of interest declaration, specified funding sources, and was open access.ResultsOur search identified 223,932 publications meeting the inclusion criteria, from which 300 were randomly sampled. Only 290 articles were accessible, yielding 202 publications with empirical data for analysis. Our results indicate that 8.99% provided access to materials, 9.41% provided access to raw data, 0.50% provided access to the analysis scripts, 0.99% linked the protocol, and 3.47% were preregistered. A third of sampled publications lacked funding or conflict of interest statements. No publications from our sample were included in replication studies, but a fifth were cited in a systematic review or meta-analysis.ConclusionsCurrent research in the field of neurology does not consistently provide information needed for reproducibility. The implications of poor research reporting can both affect patient care and increase research waste. Collaborative intervention by authors, peer reviewers, journals, and funding sources is needed to mitigate this problem.

Abstract Background This study aimed to describe and present detailed protocol of a systematic review aimed at determining available research evidence regarding the intensity, and frequency of task-specific training ( TST ) that can best result in improved motor function and mobility outcomes in both upper and lower extremities in acute, sub-acute and chronic stroke survivors. Methods Literature search strategies were developed using Medical Subject Headings (MeSH) terms and text key words related to stroke rehabilitation and the use of TST to search for relevant randomized controlled trials (RCTs). The Cochrane Central Register of Controlled Trials, MEDLINE (PubMed search engine), Excerpta Medica dataBASE (EMBASE), Physiotherapy Evidence Database (PEDro), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Google Scholar were searched for eligible articles published from inception to date. Two reviewers independently screened the titles, selected appropriate abstract/studies and extracted relevant data as yielded by the search based on the study inclusion criteria. Assessment of the study risk of bias and quality of included studies were appraised using the Cochrane’s tool for assessing risk of bias or other appropriate tools. Discussion This paper presented the description of the systematic review methods, and it is expected to guide researchers in conducting systematic review in similar fields of research. Sources of literature search terms and reviewers have been determined. Systematic review registration The study protocol has been registered with PROSPERO (130991)

AbstractDespite the increased use of medical cannabinoids, the efficacy and safety of the treatment among children remain uncertain. The objective was to study the efficacy and safety of medical cannabinoids in children. The search included studies through 11-May-2020. Selection criteria included studies evaluating efficacy and safety outcomes of medical cannabinoids (tetrahydrocannabinol, cannabidiol and other cannabis derivatives) versus control in children, independently assessed by two reviewers. Eight studies were included, all of which are randomized controlled trials. Cannabidiol is associated with 50% reduction in seizures rate (Relative Risk (RR) = 1.69, 95% CI [1.20–2.36]) and caregiver global impression of change (Median Estimated difference = (− 1), 95%CI [− 1.39–(− 0.60)]) in Dravet syndrome, compared to placebo. While cannabidiol was associated with a reduction in reported seizure events (RR = 0.59, 95% CI [0.36–0.97]), no association was found in products contained also tetrahydrocannabinol (RR = 1.35, 95% CI [0.46–4.03]). Higher dose of cannabidiol was associated with decreased appetite (RR = 2.40, 95% CI [1.39–4.15]). A qualitative assessment suggests that medical cannabinoids might be associated with adverse mental events. In conclusion, cannabidiol is associated with clinical improvement in Dravet syndrome. However, cannabidiol is also associated with decreased appetite. Adverse mental events were reported as well, however, more research should be performed to assess well this outcome.

Improved Performance

Introduction. Standard neuroimaging protocols for brain tumors have well-known limitations. The clinical use of additional modalities including amino acid PET (aaPET) and advanced MRI (aMRI) techniques (including DWI, PWI, and MRS) is emerging in response to the need for more accurate detection of brain tumors. In this systematic review of the past 2 years of the literature, we discuss the most recent studies that directly compare or combine aaPET and aMRI for brain tumor imaging. Methods. A PubMed search was conducted for human studies incorporating both aaPET and aMRI and published between July 2018 and August 2020. Results. A total of 22 studies were found in the study period. Recent studies of aaPET with DWI showed a superiority of MET, FET, FDOPA, and AMT PET for detecting tumor, predicting recurrence, diagnosing progression, and predicting survival. Combining modalities further improved performance. Comparisons of aaPET with PWI showed mixed results about spatial correlation. However, both modalities were able to detect high-grade tumors, identify tumor recurrence, differentiate recurrence from treatment effects, and predict survival. aaPET performed better on these measures than PWI, but when combined, they had the strongest results. Studies of aaPET with MRS demonstrated that both modalities have diagnostic potential but MET PET and FDOPA PET performed better than MRS. MRS suffered from some data quality issues that limited analysis in two studies, and, in one study that combined modalities, overall performance actually decreased. Four recent studies compared aaPET with emerging MRI approaches (such as CEST imaging, MR fingerprinting, and SISTINA), but the initial results remain inconclusive. Conclusions. aaPET outperformed the aMRI imaging techniques in most recent studies. DWI and PWI added meaningful complementary data, and the combination of aaPET with aMRI yielded the best results in most studies.

Abstract Objectives Lipemia is the presence of abnormally high lipoprotein concentrations in serum or plasma samples that can interfere with laboratory testing. There is little guidance available from manufacturers or professional bodies on processing lipemic samples to produce clinically acceptable results. This systematic review summarizes existing literature on the effectiveness of lipid removal techniques in reducing interference in clinical chemistry tests. Methods A PubMed search using terms relating to lipid removal from human samples for clinical chemistry tests produced 1,558 studies published between January 2010 and July 2021. 15 articles met the criteria for further analyses. Results A total of 66 analytes were investigated amongst the 15 studies, which showed highly heterogenous study designs. High-speed centrifugation was consistently effective for 13 analytes: albumin, alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, creatine kinase (CK), creatinine (Jaffe method), gamma-glutamyl transferase (GGT), glucose (hexokinase-based method), lactate dehydrogenase (LDH), phosphate, potassium, and urea. Lipid-clearing agents were uniformly effective for seven analytes: ALT, AST, total bilirubin, CK, creatinine (Jaffe method), lipase, and urea. Mixed results were reported for the remaining analytes. Conclusions For some analytes, high-speed centrifugation and/or lipid-clearing agents can be used in place of ultracentrifugation. Harmonized protocols and acceptability criteria are required to allow pooled data analysis and interpretation of different lipemic interference studies.

Purpose Patients affected by moderate to severe hallux rigidus may opt for interposition arthroplasty to avoid the movement restrictions of arthrodesis and the complications related to prosthetic replacement. The propose of this article was to review the current literature about interposition arthroplasty to examine the overall outcomes and to evaluate the advantages and disadvantages of different types of technique, compared with more consolidated procedures. Methods A literature PubMed search was performed. Studies reporting the results of interposition arthroplasty in moderate to severe hallux rigidus were included. The data were pooled and weighted for number of patients in every study. Results The overall results for interposition arthroplasties are comparable to other alternatives for end-stage hallux rigidus, providing better plantar load distribution than arthrodesis and avoiding the drawbacks of prosthetic replacement. Among the various interposition arthroplasty techniques, the Modified Oblique Keller Capsular Interposition Arthroplasty technique preserves toe length and flexor hallucis brevis function, showing the highest satisfaction rate, with lowest metatarsalgia and revision rate. Conclusion Although long-term randomized controlled trials are lacking for interposition arthroplasty, it represents a valid alternative for the treatment of end-stage hallux rigidus also in the young active patient who wants to avoid a definitive intervention immediately. Level of evidence III (systematic review of level III-IV-V studies)
