Prevalência de lesões em atletas de Brazilian jiu-jitsu: comparação entre diferentes níveis competitivos

This study aimed to identify types and sites of body injury, location of injury occurrence, and the mechanism and severity of injuries in novice and advanced Brazilian jiu-jitsu (BJJ) athletes. One hundred and eight BJJ athletes took part in this study separated in two groups: advanced (n = 53) and novice (n = 55). Athletes answered a questionnaire concerning regions of injury, locality of occurrence, injury severity and mechanism. Chi square test and a logistic regression analysis were used with the level of significance set at p < 0.05. The main results showed that shoulders and knees were the most injury location reported by novice and advanced athletes. Novice athletes demonstrated higher prevalence of injuries during training sessions (54.5%), whereas advanced athletes reported more injuries during competitions (66.1%). Significant associations between novice and advanced athletes were observed for major joints (p < 0.05). The odds ratio of having injury was 70-87% less for novice versus advanced athletes for the major joints cited. We concluded that BJJ athletes demonstrate high prevalence of injury mainly at knee and shoulder. While risk of injury appeared less in novice, the advanced demonstrated higher number of injuries during competitions as a consequence of injured joint keys. By contrast, novice athletes reported higher number of injuries associated with training sessions as a consequence of overuse.

AbstractBackgroundNear-death experiences (NDE) occur with imminent death and in situations of stress and danger but are poorly understood. Evidence suggests that NDE are associated with rapid eye movement (REM) sleep intrusion, a feature of narcolepsy. Previous studies further found REM abnormalities and an increased frequency of dream-enacting behavior in migraine patients, as well as an association between migraine with aura and narcolepsy. We therefore investigated if NDE are more common in people with migraine aura.MethodsWe recruited 1037 laypeople from 35 countries via a crowdsourcing platform. Reports were validated using the Greyson NDE Scale.ResultsEighty-one of 1037 participants had NDE (7.8%; CI 6.3-9.7%). There were no significant associations between NDE and age (p>0.6, t-test independent samples) or gender (p>0.9, chi-square test). The only significant association was between NDE and migraine aura: Forty-eight (6.1%) of 783 subjects without migraine aura and 33 (13.0%) of 254 subjects with migraine aura had NDE (p<0.001, chi-square test, odds ratio (OR) = 2.29). In multiple logistic regression analysis, migraine aura remained significant after adjustment for age (p≤0.001, OR 2.31), gender (p<0.001, OR 2.33), or both (p<0.001, OR 2.33).ConclusionsIn our sample, migraine aura was a predictor of NDE. This indirectly supports the association between NDE and REM intrusion and might have implications for the understanding of NDE, because a variant of spreading depolarization (SD), terminal SD, occurs in humans at the end of life, while a short-lasting variant of SD is considered the pathophysiological correlate of migraine aura.

Abstract Anterior open bite (AOB) has a multifactorial etiology caused by the interaction of sucking habits and genetic factors. The aim of this study was to evaluate the association between AOB and polymorphisms in genes that encode Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs). Four hundred and seventy-two children that presented at least one sucking habit were evaluated. Children were examined clinically for the presence of AOB. Genomic DNA was extracted from saliva. Genotyping of the selected polymorphisms in MMP2, MMP3, MMP9, TIMP1 and TIMP2 was carried out by real-time PCR using the TaqMan method. Allele and genotype frequencies were compared between the groups with and without AOB using the PLINK® software in a free and in a recessive model using a chi-square test. Logistic regression analysis was implemented (p≤0.05). Two hundred nineteen children had AOB while 253 did not. The polymorphism rs17576 in MMP9 was significantly associated with AOB (p=0.009). In a recessive model GG genotype was a protective factor for AOB (p=0.014; OR 4.6, 95%CI 1.3-16.2). In the logistic regression analysis, none of the genes was associated with AOB. In conclusion, the polymorphism rs17576 (glutamine for arginine substitution) in MMP9 was a protective factor for AOB.

Objective This study aimed to identify the risk factors for vertebral compression fractures in patients with osteoporosis. Methods A total of 864 patients with osteoporosis were enrolled in a retrospective study from February 2010 to June 2016. Patients with diseases, such as pathological fractures, high-energy direct injury to the thoracic or lumbar vertebrae, and severe spinal deformity, were excluded. The patients were divided into two groups: those with vertebral compression fractures (288) and those with no vertebral compression fractures (576). Information on the patients’ age, sex, lumbar bone mineral density (BMD), trauma, body mass index, previous history of vertebral compression fractures, and spondylolisthesis was recorded. Logistic regression analysis and the chi-square test were applied for comparisons. Results Univariate logistic regression analysis and chi-square test results showed no significant differences in age, sex, body mass index, type 2 diabetes, previous history of vertebral fracture, and trivial trauma between the groups. Multivariate analysis showed significant associations between spondylolisthesis and BMD. Logistic regression analysis showed that spondylolisthesis and BMD were risk factors for vertebral compression fractures. Conclusions Lumbar spondylolisthesis is an independent risk factor for vertebral compression fractures in patients with osteoporosis. Therefore, patients with osteoporosis and lumbar spondylolisthesis require more attention.

This study aims to look at the variables that affect financial sustainability. The data used are banking financial statement data contained in the FSS in 2013 to 2017. The value used to measure financial sustainability is FSS. The value of FSS as the dependent variable is divided into two categories, namely banks that are sustainable and banks that are not sustainable. Response variables used are financial ratios consisting of ROA, ROE, CTD, LTD, DTA, and CTA. The analysis used is logistic regression. Based on the results of the logistic regression model that is formed, a significant variable influences sustainability is ROA and LTA. The odds ratio values for the ROA and ROE variables are 1.2 and 2.2. This means that there is an increasing trend of 1.2 and 2.2 times for better financial sustainability with each added value of ROA and ROE. In other words, the greater the value of ROA or ROE, the greater the possibility of banking for financial sustainability. Chi-square test shows the p-value of 0.27 is greater than alpha. This shows the model meets the goodness of fit. Keywords: Financial Sustainability, Financial Ratio, Logistic Regression, Odds Ratio

Background: Persons of tribal origin account for over a quarter of India’s poorest people and also have a higher burden of disease attributable to adverse effects of tobacco use. Therefore, this study was planned in a health facility in Wayanad District to assess prevalence, pattern and determinants of tobacco use.Methods: A cross-sectional study was conducted among the persons of tribal origin by interview method using a pretested semi-structured questionnaire in a primary care facility in Wayanad, Kerala. Minimum sample size was calculated to be 140; 524 persons of tribal origin were enrolled. The chi-square test, logistic regression was used to determine association between qualitative variables.Results: Mean age of respondents was 42.52±16.95 years. The proportion of current tobacco users was found to be 39.1% (95% CI 34.9-43.4). Majority of respondents (90.2%) chewed tobacco, only 5.2% were smokers and 0.2% used other forms such as snuff. Of the tobacco users 81.95% had considered quitting. One in five persons, 19.9% used tobacco within 30 minutes of waking up. By logistic regression, men were found to be 2.59 times (95% CI 1.69, 3.97; p<0.001), illiterates 2.25 times (95% CI 1.51, .35; <0.001) and Paniya group 2.36 times (95% CI 1.6, 3.48) more likely to use tobacco.Conclusions: A high prevalence of tobacco use, early initiation and dependency, are a challenge to tobacco control among the socially and economically vulnerable indigenous people. However, the desire and attempts made to quit tobacco can be leveraged for harm reduction and tobacco cessation among males, Paniyas and illiterate people.

Hyaluronic acid-mediated motility receptor (HMMR), a tumor-related gene, plays a vital role in the occurrence and progression of various cancers. This research is aimed to reveal the effect of HMMR in lung adenocarcinoma (LUAD). We first obtained the gene expression profiles and clinical data of patients with LUAD from The Cancer Genome Atlas (TCGA) database. Then, based on the TCGA cohort, the HMMR expression difference between LUAD tissues and nontumor tissues was detected and verified with public tissue microarrays (TMAs), clinical LUAD specimen cohort, and Gene Expression Omnibus (GEO) cohort. Logistic regression analysis and chi-square test were adopted to study the correlation between HMMR expression and clinicopathological parameters. The effect of HMMR expression on survival was evaluated by Kaplan–Meier survival analysis and using the Cox regression model. Furthermore, Gene Set Enrichment Analysis (GSEA) was utilized to screen out signaling pathways related to LUAD and the co-expression analysis was employed to build the protein–protein interaction (PPI) network. The HMMR expression level in LUAD tissues was dramatically higher than that in nontumor tissues. Logistic regression analysis and chi-square test demonstrated that the high HMMR expression in LUAD has relation with gender, pathological stage, T classification, lymph node metastasis, and distant metastasis. The Kaplan–Meier curve suggested a poor prognosis for LUAD patients with high HMMR expression. Multivariate analysis implied that the high HMMR expression was a vital independent predictor of poor overall survival (OS). GSEA indicated that a total of 15 signaling pathways were enriched in samples with the high HMMR expression phenotype. The PPI network gave 10 genes co-expressed with HMMR. HMMR may be an oncogene in LUAD and is expected to become a potential prognostic indicator and therapeutic target for LUAD.

Congenital heart disease (CHD) is a congenital condition caused by a lack of heart development during the fetal stage. There is a notion that children with CHD have low nutritional status due to their condition. Nutritional input, energy requirements, dietary components, and prenatal circumstances impact a person's nutritional status. An analytical observational design with a cross-sectional approach was used in this research. Data were obtained via medical records and questionnaires posed to the patients' guardians who had provided informed consent. The Chi-square test and multivariate logistic regression analysis were used to analyze the data. The study was conducted on 62 subjects. There were 74.19% of subjects with acyanotic CHD and 25.81% with cyanotic CHD. 61.29 % of the subjects were exclusively breastfed for the first six months. The Chi-Square test revealed a relationship between breastfeeding and the nutritional status of children with CHD, with p = 0.0001 (p<0.05). The multivariate logistic regression analysis showed the significance of the type of CHD suffered by the subjects was 0.003 (p<0.05). There is a significant association between breastfeeding for the first six months and the type of CHD suffered by children with their nutritional status at Dr. Soetomo General Hospital.

Abstract Background This study aimed to assess the level of trust in the COVID-19 risk communication efforts in Nigeria. Methods We conducted a descriptive cross-sectional study among community members aged 15 years and above in Ondo state in October, 2020. Data were collected using an interviewer-administered questionnaire. Data were analyzed using SPSS version 22. Descriptive statistics were summarized using frequencies. Trust was ranked from “1” implying “Low level of trust” to “7” denoting “High level of trust”. We conducted bivariate Chi-square test on respondents’ level of trust in the Nigeria Centre for Disease Control (NCDC) and socio-demographic characteristics. The level of significance was set at p<0.05. Results Among the 691 respondents, 244 (35.3%) were aged 21 to 29 years, and 304 (51.4%) used the NCDC to obtain COVID-19 knowledge. Overall, 205 (41.8%) had high level of trust in the NCDC. Furthermore, 51 (51.5%) individuals aged 30-39 years had high level of trust in the NCDC (ᵡ2=17.455, p= 0.001). Also, 114 (48.5%) persons who lived with children below 18 years had high level of trust in the NCDC (ᵡ2= 8.266, p= 0.004). Conclusion Policy makers should prioritize the involvement of young and educated persons in COVID-19 risk communication strategies.
