RESUMO

INTRODUCTION: This study aimed to compare patients' Salzmann Index scores for those who applied for Medicaid orthodontic coverage in Pennsylvania with their corresponding American Board of Orthodontics discrepancy index (DI) scores to assess if there is a correlation between Salzmann and DI scores. In addition, a threshold DI score was calculated that would correspond to Medicaid coverage approval. The study intended to answer the following questions: is there a correlation of 0.7 or greater between a patient's Salzmann Index and their DI? If so, is there a particular DI score that can be used as the minimum score for approving Medicaid orthodontic coverage in the state of Pennsylvania? METHODS: Salzmann Index scores, DI scores, and approval and disapproval results for Medicaid orthodontic coverage were obtained from 104 subjects aged between 10 and 17 years. A linear regression model was generated to assess if there was a correlation between the Salzmann scores and DI scores. If a correlation coefficient of 0.7 or greater were found, a threshold Salzmann Index score would be determined for subjects who were approved for Medicaid orthodontic coverage. The threshold Salzmann score would be used in the linear regression formula to find the corresponding DI score, which would be designated as the threshold DI score for approval for Medicaid orthodontic coverage in the state of Pennsylvania. RESULTS: A Pearson correlation of 0.453 was calculated between the 104 Salzmann scores and DI scores, demonstrating a moderate correlation. With the correlation coefficient being lower than 0.7, binary logistic regressions were calculated to assess the predictability between a given Salzmann score and approval and disapproval for Medicaid orthodontic coverage. The Salzmann score had an overall 68.3% success in predicting Medicaid orthodontic coverage approval/disapproval. Of the 58 subjects that were approved for Medicaid orthodontic coverage, 46.6% had Salzmann scores equal to or greater than 25. Of the 46 subjects that were disapproved for Medicaid orthodontic coverage, 78.3% had Salzmann scores equal to or less than 24. CONCLUSIONS: With the lack of high prediction rates seen from the results of the regression models, the current system of Medicaid does not appear to show consistency for assessing the need for orthodontic treatment coverage. Multiple insurance companies that participate under Medicaid require a Salzmann score of 25 or greater for approval; however, the results show the Salzmann score is arbitrary in terms of approval and disapproval. There appear to be underlying factors apart from the Salzmann score that the Pennsylvania Medicaid system uses to justify whether a patient was approved or denied for coverage.

RESUMO

INTRODUCTION: Scientific evidence in medicine is based on data generated from research. Recently, the number of scientifically active physicians has decreased, which has led to the development of the Clinician Scientist Programs. To better structure and focus the research of young physicians, we aimed to investigate the impact of collaborations and other factors on the quality and output of scientific publications. METHODS: The abstracts of three annual congresses of the German Society of Urology were systematically analysed regarding content, collaborations, and study design. Full-text publications and journals were identified through a MEDLINE® search. Impact factors (IFs) were identified using Journal Citation Reports™. To identify factors which predict publication and IFs, χ2 and Wilcoxon rank-sum tests were used. Uni- and multivariable logistic regression analyses were performed to assess the best model for publication success for an abstract as well as the achievement of a high IF. RESULTS: 1,074 abstracts were reviewed. The publication rate of subsequent peer-reviewed full-text publications was 52.5%. Collaborations with at least one institution (odds ratio (OR) 2.02, 95% confidence interval (CI) 1.48-2.76, p <0.0001), statistical analysis (OR 1.92, 95% CI 1.41-2.60, p <0.0001), study design (prospective vs. retrospective: OR 1.43, 95% CI 1.06-1.93, p=0.021), and national collaborations (OR 1.43, 95% CI 1.04-1.98, p=0.029) increased the likelihood of publication in a peer-reviewed journal in a multivariable logistic regression analysis. Experimental design (OR 2.77, 95% CI 1.32-5.84, p=0.007), international collaborations (OR 2.26, 95% CI 1.23-4.15, p=0.009), oncologic topics (OR 1.94, 95% CI 1.23-3.07, p=0.005), prostate disease (OR 1.75, 95% CI 1.08-2.84, p=0.023), and statistical analysis (OR 1.68, 95% CI 1.06-2.64, p=0.026) were associated with a higher IF. CONCLUSION: Abstracts resulting from collaborative research projects had a higher likelihood of subsequent full-text publication and a higher IF. More full-text publications were reported when abstracts included a statistical analysis. Hence, intensive networking (e. g. at congresses and workshops) of researching physicians as well as statistical/biometrical classes could be key factors to improve academic success.

RESUMO

BACKGROUND: Graphs are mathematical structures widely used for expressing relationships among elements when representing biomedical and biological information. On top of these representations, several analyses are performed. A common task is the search of one substructure within one graph, called target. The problem is referred to as one-to-one subgraph search, and it is known to be NP-complete. Heuristics and indexing techniques can be applied to facilitate the search. Indexing techniques are also exploited in the context of searching in a collection of target graphs, referred to as one-to-many subgraph problem. Filter-and-verification methods that use indexing approaches provide a fast pruning of target graphs or parts of them that do not contain the query. The expensive verification phase is then performed only on the subset of promising targets. Indexing strategies extract graph features at a sufficient granularity level for performing a powerful filtering step. Features are memorized in data structures allowing an efficient access. Indexing size, querying time and filtering power are key points for the development of efficient subgraph searching solutions. RESULTS: An existing approach, GRAPES, has been shown to have good performance in terms of speed-up for both one-to-one and one-to-many cases. However, it suffers in the size of the built index. For this reason, we propose GRAPES-DD, a modified version of GRAPES in which the indexing structure has been replaced with a Decision Diagram. Decision Diagrams are a broad class of data structures widely used to encode and manipulate functions efficiently. Experiments on biomedical structures and synthetic graphs have confirmed our expectation showing that GRAPES-DD has substantially reduced the memory utilization compared to GRAPES without worsening the searching time. CONCLUSION: The use of Decision Diagrams for searching in biochemical and biological graphs is completely new and potentially promising thanks to their ability to encode compactly sets by exploiting their structure and regularity, and to manipulate entire sets of elements at once, instead of exploring each single element explicitly. Search strategies based on Decision Diagram makes the indexing for biochemical graphs, and not only, more affordable allowing us to potentially deal with huge and ever growing collections of biochemical and biological structures.

RESUMO

Currently, many a priori indexes are being used to assess maternal adherence to the Mediterranean diet (MD) during pregnancy but each with different components, cut-off points, and scoring systems. This narrative review aimed to identify all observational studies utilizing a priori indexes to assess maternal adherence to the MD during pregnancy. A systematic search was conducted in Pubmed until 1 July 2020. Among the 27 studies included, eight different a priori indexes were identified. Studies included a range of 5 to 13 dietary components in their indexes. Only three dietary components-vegetables, fruits, and fish-were common among all indexes. Dairy and alcohol were the only two components modified for pregnancy. All but one study either excluded alcohol from their index or reversed its scoring to contribute to decreased adherence to the MD. Approximately half of the studies established cut-off points based on the distribution of the study population; the others utilized fixed criteria. This review emphasizes the incongruent definitions of the MD impairing effective comparison among studies relating to maternal or offspring health outcomes. Future research should carefully consider the heterogeneous definitions of the MD in a priori indexes and the relevance of incorporating pregnancy-specific nutritional requirements.

RESUMO

BACKGROUND: Cerebrovascular diseases (CBVD) are the second major cause of death in the world. OBJECTIVE: To analyze the mortality trend of CBVD in Brazil (1996 to 2015) and its association with Human Development Index (HDI) and the Social Vulnerability Index (SVI). METHODS: This is an ecological study. We analyzed the mortality rate standardized by CBVD. Death data were obtained from the Mortality Information System (SIM) and populational data from the Brazilian Institute of Geography and Statistics (IBGE). The model of regression by inflection points (Joinpoint regression) was used to perform the temporal analysis, calculating the Annual Percent Change (APC) and Average Annual Percent Change (AAPC), with 95% of confidence interval and a significance of 5%. Trends were classified as increasing, decreasing or stationary. A multivariate regression model was used to analyze the association between mortality by CBVD, HDI and SVI. RESULTS: During this period, 1,850,811 deaths by CBVD were recorded. We observed a reduction in the national mortality rate (APC -2.4; p = 0.001). Twenty federation units showed a significant trend, of which 13 showed reduction, including all states in the Midwest (n=4), Southeast (n=4) and South (n=3). The HDI was positively associated and the SVI was negatively associated with mortality (p = 0.046 and p = 0.026, respectively). CONCLUSION: An unequal epidemiological course of mortality was observed between the regions, being higher in the Southeast and South states, with a significative tendency of reduction, and lower in the North and Northeast states, but with a significative tendency of increase. HDI and SVI showed an association with mortality. (Arq Bras Cardiol. 2021; 116(1):89-99).

RESUMO

The Librarian Reserve Corps (LRC) is a volunteer network of medical, health sciences, and public health librarians who have responded to the urgent need for public health information during the early days of the COVID-19 crisis. The LRC was first formed to assist with the indexing of daily publication lists distributed within the World Health Organization's Global Outbreak Alert and Response Network (GOARN). With the explosion of information related to COVID-19 beginning in December 2019, librarians have brought critical skills and experience to the response, providing comprehensive literature searching and indexing to COVID-19 research publications. The evolution of this effort follows the trajectory of scientific publication trends and developments related to COVID-19.

RESUMO

AIM: The progress of a discipline depends on the knowledge widely shared, an aim fulfilled by publications. But which are the factors influencing publication? We examine predictors of a subsequent publication for abstracts submitted to the annual scientific conference of the German Society of Orthodontics (DGKFO). METHODS: For all 288 abstracts presented in 2014 and 2015 we recorded presentation format, number and gender of authors, study design and university affiliation. Subsequent publication as a peer-reviewed full-text article was researched over a period of more than three years. RESULTS: A total of 88 abstracts (30.6 %) were published in full-text after a mean time span of 1.2±1.6 years after the respective conference. In multivariate logistic regression, secondary studies (OR 9.27 [1.51-57.04]; p=0.016), a higher number of authors (OR 1.21 [1.02-1.43]; p=0.030), a higher percentage of female authors (OR 1.01 [1.00-1.03]; p=0.036) but male gender of the first author (OR 2.10 [1.11-3.98]; p=0.023) resulted in a higher probability of getting published as a journal paper. CONCLUSION: Our investigation shows that secondary studies, a higher number of authors, a higher percentage of women among the authors and male first authors are predictive factors of publication. After more than three years, only about one third of the abstracts presented at the DGKFO annual scientific conference have been published as a full-text journal article, meaning that a huge part of knowledge remains unshared.

RESUMO

Myoelectric prostheses are commonly controlled by surface EMG. Many control algorithms, including the user learning-based control paradigm abstract control, benefit from independent control signals. Measuring at the surface of the skin reduces the signal independence through cross talk. To increase the number of independent signals, intramuscular EMG recordings might be a viable alternative for myoelectric control. This proof of concept study investigated if real time abstract myoelectric control is possible with intramuscular measurements. Six participants performed a 4-target and 12-target abstract control task with both surface and intramuscular EMG recordings. The results suggest that intramuscular EMG is suitable for abstract control, and that performance could be increased in the future by stabilizing the amplitude of the processed intramuscular EMG signal.

RESUMO

BACKGROUND: Randomized controlled trials (RCTs) provide the highest level of evidence and are likely to influence clinical decision-making. This study evaluated the reporting quality of RCT abstracts on drug therapy of periodontal disease and assessed the associated factors. MATERIAL AND METHODS: The Pubmed database was searched for periodontal RCTs published in Science Citation Indexed (SCI) dental journals from 2010/01/01 to 2019/07/17. Information was extracted from the abstracts according to a modified Consolidated Standards of Reporting Trials (CONSORT) guideline checklist. The data was analyzed using descriptive statistical analysis and the statistical associations were examined using the linear regression analysis (P < 0.05). RESULTS: This study retrieved 1715 articles and 249 of them were finally included. The average overall CONSORT score was 15.6 ± 3.4, which represented 40.9% (±0.6) of CONSORT criteria filling. The reporting rate of some items (trial design, numbers analyzed, confidence intervals, intention-to-treat analysis or per-protocol analysis, harms, registration) was less than 30%. The adequate reporting rate of some items (participants, randomization, numbers analyzed, confidence intervals, intention-to-treat analysis or per protocol analysis) was no more than 4%. None of the abstracts reported funding. According to the multivariable linear regression results, number of authors (P = 0.030), word count (P < 0.001), continent (P = 0.003), structured format (P < 0.001), type of periodontal disease (P < 0.001) and international collaboration (P = 0.023) have a significant association with reporting quality. CONCLUSIONS: The quality of RCT abstracts on drug therapy of periodontal disease in SCI dental journals remained suboptimal. More efforts should be made to improve RCT abstracts reporting quality

RESUMO

The abstract of a scientific research paper must be well written and reviewed. Sometimes is the only section of a paper that is read, therefore must have the problem, research question, objective, hypothesis, method, results and conclusions, with the limitation of the study. Editors through the abstract deduce what a paper is about and its scientific relevance. The title condenses the paper's content in a few words, must capture the reader's attention and includes patients and methods. Both, the research summary and title of the paper are used for references databases. The paper gives some tips to write a good research abstract and title.


El resumen de un artículo científico debe ser prolíjamente redactado y revisado ya que muchas veces es lo único que se lee. Debe ser específico y representativo del texto, describiendo el problema, el objetivo, la hipótesis, cómo se hizo la investigación y que resultados se obtuvieron con sus conclusiones, mostrando las limitaciones del estudio. El título debe llamar la atención del lector y describir los pacientes y el método en forma breve. Es en base al resumen que editores evaluan la validez y relevancia del artículo científico. El título y resumen es lo que se incorpora en las bases de datos bibliográficas. En este artículo se describen los pasos para la redacción de un resumen de un buen artículo científico.

RESUMO

BACKGROUND: Text mining with automatic extraction of key features is gaining increasing importance in science and particularly medicine due to the rapidly increasing number of publications. OBJECTIVES: Here we evaluate the current potential of sentiment analysis and machine learning to extract the importance of the reported results and conclusions of randomized trials on stroke. METHODS: PubMed abstracts of 200 recent reports of randomized trials were reviewed and manually classified according to the estimated importance of the studies. Importance of the papers was classified as "game changer", "suggestive", "maybe" "negative result". Algorithmic sentiment analysis was subsequently used on both the "Results" and the "Conclusions" paragraphs, resulting in a numerical output for polarity and subjectivity. The result of the human assessment was then compared to polarity and subjectivity. In addition, a neural network using the Keras platform built on Tensorflow and Python was trained to map the "Results" and "Conclusions" to the dichotomized human assessment (1: "game changer" or "suggestive"; 0:"maybe" or "negative", or no results reported). 120 abstracts were used as the training set and 80 as the test set. RESULTS: 9 out of the 200 reports were classified manually as "game changer", 40 as "suggestive", 73 as "maybe" and 32 and "negative"; 46 abstracts did not contain any results. Polarity was generally higher for the "Conclusions" than for the "Results". Polarity was highest for the "Conclusions" classified as "suggestive". Subjectivity was also higher in the classes "suggestive" and "maybe" than in the classes "game changer" and "negative". The trained neural network provided a correct dichotomized output with an accuracy of 71% based on the "Results" and 73% based on "Conclusions" . CONCLUSIONS: Current statistical approaches to text analysis can grasp the impact of scientific medical abstracts to a certain degree. Sentiment analysis showed that mediocre results are apparently written in more enthusiastic words than clearly positive or negative results.

RESUMO

The purpose of this study was to investigate the effect of a telerehabilitation system on the quality of sleep in patients with multiple sclerosis (PwMS). Fifteen females and two males (60.1 ± 11.4 years) who used the system for three months completed the Pittsburg Sleep Quality Index (PSQI) at the baseline and end of follow-up. Total System Usage (TSU) and Total Exercise Time (TET) were elucidated from the system web logs for each PwMS. A significant association (p<0.05) was found between PSQI sleep efficiency (SE) and TSU (0.76) and between SE and TET (0.81). The association between PSQI total score (TS) and TSU and between TS and TET were -0.507 and -0.702 respectively (p<0.05). Our results uncovered an association between amount of exercise time spent by PwMS and positive effects on both the efficiency and quality of sleep. Thus, further development of approaches promoting continuous participation of PwMS in telerehabilitation is warranted.

RESUMO

The Swiss Variant Interpretation Platform for Oncology is a centralized, joint and curated database for clinical somatic variants piloted by a board of Swiss healthcare institutions and operated by the SIB Swiss Institute of Bioinformatics. To support this effort, SIB Text Mining designed a set of text analytics services. This report focuses on three of those services. First, the automatic annotations of the literature with a set of terminologies have been performed, resulting in a large annotated version of MEDLINE and PMC. Second, a generator of variant synonyms for single nucleotide variants has been developed using publicly available data resources, as well as patterns of non-standard formats, often found in the literature. Third, a literature ranking service enables to retrieve a ranked set of MEDLINE abstracts given a variant and optionally a diagnosis. The annotation of MEDLINE and PMC resulted in a total of respectively 785,181,199 and 1,156,060,212 annotations, which means an average of 26 and 425 annotations per abstract and full-text article. The generator of variant synonyms enables to retrieve up to 42 synonyms for a variant. The literature ranking service reaches a precision (P10) of 63%, which means that almost two-thirds of the top-10 returned abstracts are judged relevant. Further services will be implemented to complete this set of services, such as a service to retrieve relevant clinical trials for a patient and a literature ranking service for full-text articles.
