Association between self-reported bruxism and academic performance in university students.

Objective: To evaluate the association between self-reported bruxism and academic performance in students at a university in Lima, Peru. Material and Methods: A total of 203 students were evaluated in this study, between the ages of 19 and 35 years. Self-reported bruxism was measured using the Bruxism Assessment Questionnaire. Academic performance was evaluated using the Approval Index Scale. In addition, other variables were included such as employment status, socioeconomic level, stress, anxiety, among others. The association of variables were factored in using the chi-square test and the logistic regression presented the unadjusted and adjusted analisis. Results: The frequency of self-reported awake bruxism and sleep bruxism was 53.20% and 36.45%, respectively. Evidence revealed there was a statistically significant association between awake bruxism with stress and anxiety, and sleep bruxism with anxiety. Students with high academic performance (OR=2.36; IC del 95%:1.06-5.23) and low academic performance (OR=5.72; IC del 95%:1.28-25.57) were found to be more likely to have awake bruxism than those with medium academic performance. Conclusion: This study revealed a statistically significant association between self-reported awake bruxism and academic performance. However, in the future it is suggested to carry out a study with focus only on students with bruxism and with a larger sample of participants with low academic performance to confirm the association found between these variables.

Abstract Aims Gestational diabetes (GDM) increases the risk of developing type 2 diabetes and thus warrants earlier and more frequent screening. Women who give birth to a macrosomic infant, as defined as a birthweight greater than 9 lbs. (or approximately 4000 g), are encouraged to also get early type 2 diabetes screening, as macrosomia may be a surrogate marker for GDM. This study investigates whether a macrosomic infant, as defined as 9lbs, apart from GDM, increases the risk for diabetes later in life. Methods Data on parous women from the National Health and Nutrition Examination Survey (NHANES) 2007–2016 were utilized. Rates of diabetes were compared in those with and without macrosomic infants in Rao-Scott’s chi-square test. Multiple logistic regression was used to test the independent effect of macrosomia on type 2 diabetes controlling for the confounding covariates and adjusting for the complex sampling design. To investigate how onset time affects diabetes, we implemented Cox proportional hazard regressions on time to have diabetes. Results Among 10,089 parous women, macrosomia significantly increased the risk of maternal diabetes later in life in the chi-square test and logistic regression. Independent of GDM, women who deliver a macrosomic infant have a 20% higher chance of developing diabetes compared to women who did not. The expected hazards of having type 2 diabetes is 1.66 times higher in a woman with macrosomic infant compared to counterparts. Conclusions Women who gave birth to a macrosomic infant in the absence of GDM should be offered earlier and more frequent screening for type 2 diabetes.

Background: Given the widespread prevalence and serious nature of Internet addiction (IA), this study aimed to estimate the prevalence of IA and assess the relationships between IA and combinations of physical activity (PA) and screen-based sedentary behavior (SB) among adolescents in China. Methods: This cross-sectional study surveyed 31,954 adolescents in grades 7 to 12 in Beijing. IA, PA, screen-based SB, and other information were obtained from a self-administrated questionnaire. The chi-square test and mixed-effects logistic regression model were applied to estimate the relationship between IA and combinations of PA and screen-based SB. Results: 6.2% of the surveyed adolescents reported IA and the prevalence of low PA/high screen-based SB, high PA/high screen-based SB, low PA/low screen-based SB, and high PA/low screen-based SB were 53.7%, 19.5%, 18.8%, and 8.0%, respectively. Mixed-effects logistic regression analysis showed that adolescents with low PA/high screen-based SB were 1.99 (95% confidence interval, 1.62–2.44, P < .001) times more likely to prefer IA than those with high PA/low screen-based SB. Conclusions: The prevalence of IA among Chinese adolescents is still high. Intervention programs like maintaining sufficient PA and reducing screen-based SB might contribute to reducing their IA.

Abstract Background: Dysphagia is one of the most common complications after anterior cervical spine surgery. The study aimed to evaluate the risk factors for dysphagia after anterior cervical discectomy and fusion (ACDF) with the Zero-P Implant System by multidimensional analysis and investigated the predictive values of these risk factors for dysphagia. Methods: A retrospective analysis of 260 patients who underwent ACDF with the Zero-P Implant System and had at least 2 year of follow-up ware performed. All patients were divided into a non-dysphagia group and a dysphagia group. Sex, age, body mass index (BMI), intraoperative time, estimated blood loss, diabetes mellitus, hypertension, smoking, alcohol consumption, prevertebral soft-tissue thickness, the levels of surgery, O-C2 angle, C2–7 angle, T1 slope and segmental angle were analyzed. Chi-square test and logistic regression were performed to analyze the predictive value of each dimension for dysphagia. Results: In total, the non-dysphagia group comprised 170 patients and the dysphagia group comprised 90 patients. Chi-square test results indicated that number of operated levels, operation time dT1 slope, dO-C2 angle, dC2–7 angle, segmental angle and dPSTT were associated with a high incidence of dysphagia. Multivariate logistic regression analysis showed that number of operated levels, operation time, dC2–7 angle and dPSTT were significantly associated with postoperative dysphagia.Conclusions: Number of operated levels, operation time, dC2–7 angle and dPSTT were significantly associated with postoperative dysphagia. In additionally, sufficient preoperative preparation, evaluation combining with proficient and precise treatment measures are suggested to reduce the incidence of postoperative dysphagia when ACDF is performed.

The improvement of patients’ food satisfaction and acceptance in the hospitals is primarily needed in the food service system. Room service is a new concept in the food service area. This study aims to compare the effects of two different types of food service systems; room service and conventional service system. The study with quasi-experimental design is conducted to the subject of 66 inpatients who were taken using a quota sampling method. Subjects were divided into different groups, the treatment groups (room service) and control groups (conventional). Leftover food between groups was compared for 9 large meals to determine acceptability. Food satisfaction is measured on the last day with using questionnaire. The study was conducted in April-June 2014. Chi-Square test and logistic regression were used for analysis of research data. There were significant differences food satisfaction (RR=4.6; p=0.0001) and food acceptance (RR=1.94; p=0.0488) between control and treatment group. The logistic regression test showed that room service group had higher food satisfaction and food acceptance level than control group after controlling confounding factors, which were 12,11 times (95% CI 3,593 – 37,219) and 2,38 times (95% CI 0,68-8,31), respectively. The room service increases food satisfaction and food acceptance of patients compared with conventional systems.

Abstract Background: Thailand lacks evidence of the current prevalence of workplace violence (WPV) at tertiary hospitals. This study aimed to examine the prevalence of, perpetrators of, and factors associated with WPV against healthcare workers in excellent tertiary hospitals in Thailand.Methods: This was a mixed-methods study. A questionnaire was individually administered by an interviewer to 220 healthcare workers using a tablet with an online platforms, and the completion rate was 100%. The study was conducted from July 2018 to March 2019. Pearson’s chi-square test was used to examine the variables related to any violence according to individual and work data. Odds ratios with 95% confidence intervals were used to assess risk factors for exposure to violence using a logistic regression model. Thirty participants provided additional qualitative data that were used for thematic analysis.Results: The findings revealed that in the past 12 months, 63.6% of the participants experienced violence at their workplaces. The most common type of violence reported was verbal violence (56.4%), followed by physical violence (24.1%), bullying (16.4%), sexual harassment (4.1%), and racial harassment (3.6%). Multivariable logistic regression revealed that the correlates of violence at hospitals included being male (OR = 4.28, 95% CI 1.50–12.19), working in an outpatient department (OR = 2.55, 95% CI 1.42–4.58), and having direct contact with clients (OR = 3.12, 95% CI 1.25–7.73). The qualitative data revealed 5 major themes.Conclusion: There is a high prevalence of violence against all healthcare workers at excellent tertiary hospitals in Thailand. Policymakers need to be aware of the roots and risk factors for all types of WPV. The results could also contribute to the development of appropriate policies, interventions for conflicts based on intergenerational gaps, reporting, investigation processes, preventive measures, and zero-tolerance protocols for all healthcare workers.

Background: During the Covid-19 outbreak, health workers, especially nurses, are vulnerable to potential psychological symptoms such as anxiety, which can prevent nurses from carrying out their role as caregivers in health services (Lai et al., 2020; Shanafelt et al., 2020). Objectives: The purpose of this study is to analyze the factors that can influence the anxiety of nurses in playing the role of caregiver during the Covid-19 pandemic. Methods: This is a cross-sectional study with a population of all nurses who met the inclusion criteria as much as 105 nurses. The research sample was selected through stratified random sampling and obtained 84 nurses. This research was conducted at RSI Jemursari Surabaya from June until September 2020. The research instruments used in this study were the demographic observation sheet, knowledge questionnaire, and the Hamilton Anxiety Rank Scale (HARS). Data analysis used Pearson chi-square test and multivariate logistic regression. Results: The results of the Pearson Chi-square test showed that of all the factors studied, only age (p = 0.004), availability of personal protective equipment (p = 0.002), and knowledge (p = 0.017) influenced nurses' anxiety. The results of the analysis using multivariate logistic regression test showed that the factor that most influenced nurses' anxiety was the availability of personal protective equipment (p = 0.001; OR = -3.062). Conclusion: Younger nurses, inadequate personal protective equipment, and less knowledgeable nurses were at high risk for more severe anxiety. Regular observation of the psychological condition of nurses and the fulfillment of the need for personal protective equipment is needed to prevent increased anxiety in nurses.

The present article is an attempt to analyze the various factors affecting the adoption of an activity-based costing (ABC) system in selected manufacturing units in India. The following seven factors are considered: firm size, diversity of the product, percentage of overhead cost in total cost, listing of the company, cost audit compulsion, separate cost accounting department and the method of accounting. Logistic regression and a Chi Square test are applied to these factors and the use of an ABC system. On the basis of 72 sample units, the study found the size of the firm, percentage of overhead cost in total cost, cost audit compulsion and the method of accounting are statistically significant for the adoption of ABC system. While factors such as diversity of the product, separate cost accounting department and the listing of the company are found to not be statistically significant for the adoption of ABC system. The study has provided additional insights into areas relating to the factors affecting the implementation of ABC systems.

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.
