ABSTRACT

AIMS: To analyze Axis I and II findings of patients diagnosed as having painful temporomandibular disorder (TMD) with headache attributed to TMD (HAattrTMD) in order to assess whether HAattrTMD is associated with a specific Axis I and II profile suggestive of the central sensitization process.

METHODS: This retrospective study included 220 patients with painful TMD divided into those with (n = 60) and those without (n = 160) HAattrTMD, and the patients were compared for Axis I and II results according to the Diagnostic Criteria for TMD (DC/TMD). A P value < .05 was considered statistically significant.

RESULTS: A total of 27.3% of the patients received a diagnosis of HAattrTMD. Myofascial pain with referral was significantly more common in the HAattrTMD group (P < .001), while local myalgia was significantly more common in the non-HAattrTMD group (P < .001). Characteristic pain intensity was significantly higher in the HAattrTMD group (P = .003), which also showed significantly higher levels of depression (P = .002), nonspecific physical symptoms (P = .004), graded chronic pain (P = .008), and pain catastrophizing (P = .013). Nonspecific physical symptoms were positively associated with HAattrTMD (odds ratio [OR] = 1.098, 95% CI = 1.006 to 1.200, P = .037). Local myalgia was negatively associated with HAattrTMD (OR = .295, 95% CI = 0.098 to 0.887, P = .030).

CONCLUSIONS: Painful TMD patients who report headache in the temple area and are diagnosed as having local myalgia rather than myofascial pain with referral probably do not have HAattrTMD. The diagnosis of HAattrTMD may point to a central sensitization process and possible current/future chronic TMD conditions.

ABSTRACT

AIMS: To answer the question: among observational studies, is there any association between primary headaches and bruxism in adults?

MATERIALS AND METHODS: A systematic review of observational studies was performed. The search was performed in seven main databases and three gray literature databases. Studies in which samples were composed of adult patients were included. Primary headaches were required to be diagnosed by the International Classification of Headache Disorders. Any diagnostic method for bruxism was accepted. Risk of bias was evaluated using the Joanna Briggs Institute Critical Appraisal Tool and the Meta-Analysis of Statistics Assessment and Review Instrument (MAStARI) tool. Associations were analyzed by calculating odds ratios (OR) in Review Manager 5.3 software. The evidence certainty was screened by Grading of Recommendations Assessment, Development, and Evaluation criteria.

RESULTS: Of the 544 articles reviewed, 5 met the inclusion criteria for qualitative analysis. The included studies evaluated both awake and sleep bruxism, as well as tension-type headaches and migraines as primary headaches. Among two migraine studies, one showed an OR of 1.79 (95% CI: 0.96 to 3.33) and another 1.97 (95% CI: 1.5 to 2.55). On the other hand, among three tension-type headache studies, there was a positive association only with awake bruxism, with an OR of 5.23 (95% CI: 2.57 to 10.65). All included articles had a positive answer for more than 60% of the risk of bias questions. The evidence certainty varied between low and very low. Due to high heterogeneity among the studies, it was impossible to perform a meta-analysis.

CONCLUSION: Patients with awake bruxism have from 5 to 17 times more chance of having tension-type headaches. Sleep bruxism did not have any association with tension-type headache, and the association with migraines is controversial.

ABSTRACT

INTRODUCTION: Religion and spirituality play important roles in the lives of many, including healthcare providers and their patients. The purpose of this study was to examine the relationships between religion, spirituality, and cultural competence of healthcare providers.

METHODS: Physicians, residents, and medical students were recruited through social platforms to complete an electronically delivered survey, gathering data regarding demographics, cultural competency, religiosity, and spirituality. Four composite variables were created to categorize cultural competency: Patient Care Knowledge, Patient Care Skills/Abilities, Professional Interactions, and Systems Level Interactions. Study participants (n = 144) were grouped as Christian (n = 95)/non-Christian (n = 49) and highly religious (n = 62)/not highly religious (n = 82); each group received a score in the four categories. Wilcoxon rank sum and Chi-square tests were used for analysis of continuous and discrete variables.

RESULTS: A total of 144 individuals completed the survey with the majority having completed medical school (n = 87), identifying as women (n = 108), white (n = 85), Christian (n = 95), and not highly religious (n = 82). There were no significant differences amongst Christian versus non-Christian groups or highly religious versus not highly religious groups when comparing their patient care knowledge (p = .563, p = .457), skills/abilities (p = .423, p = .51), professional interactions (p = .191, p = .439), or systems level interaction scores (p = .809, p = .078). Nevertheless, participants reported decreased knowledge of different healing traditions (90%) and decreased skills inquiring about religious/spiritual and cultural beliefs that may affect patient care (91% and 88%). Providers also reported rarely referring patients to religious services (86%).

CONCLUSIONS: Although this study demonstrated no significant impact of healthcare providers’ religious/spiritual beliefs on the ability to deliver culturally competent care, it did reveal gaps around how religion and spirituality interact with health and healthcare. This suggests a need for improved cultural competence education.

ABSTRACT

OBJECTIVE: The discrepancy between admission and discharge diagnosis can lead to possible adverse patient outcomes. There are gaps in integrated studies, and less is understood about its characteristics and effects. Therefore, this study was conducted to determine the frequency, characteristics, and outcomes of diagnostic discrepancies at admission and discharge.

DESIGN AND DATA SOURCES: This retrospective study reviewed the admitting and discharge diagnoses of adult patients admitted at Aga Khan University Hospital (AKUH), Internal Medicine Department between October 2018 and February 2019. The frequency and outcomes of discrepancies in patient diagnoses were noted among Emergency Department (ED) physician versus admitting physician, admitting physician versus discharge physician, and ED physician versus discharge physician for the full match, partial match, and mismatch diagnoses. The studied outcomes included interdepartmental transfer, Intensive Care Unit (ICU) transfer, in-hospital mortality, readmission within 30 days, and the length of stay. For simplicity, we only analyzed the factors for the discrepancy among ED physicians and discharge physicians.

RESULTS: Out of 537 admissions, there were 25.3-27.2% admissions with full match diagnoses while 18.6-19.4% and 45.3-47.9% had mismatch and partial match diagnoses respectively. The discrepancy resulted in an increased number of interdepartmental transfers (5-5.8%), ICU transfers (5.6-8.7%), in-hospital mortality (8-11%), and readmissions within 30 days in ED (14.4%-16.7%). A statistically significant difference was observed for the ward’s length of stay with the most prolonged stay in partially matched diagnoses (6.3 ± 5.4 days). Among all the factors that were evaluated for the diagnostic discrepancy, older age, multi-morbidities, level of trainee clerking the patient, review by ED faculty, incomplete history, and delay in investigations at ED were associated with significant discrepant diagnoses.

CONCLUSIONS: Diagnostic discrepancies are a relevant and significant healthcare problem. Fixed patient or physician characteristics do not readily predict diagnostic discrepancies. To reduce the diagnostic discrepancy, emphasis should be given to good history taking and thorough physical examination. Patients with older age and multi-morbidity should receive significant consideration.

ABSTRACT

AIMS: To test the hypothesis that, in comparison with control, experimental noxious stimulation of the right masseter muscle would result in significant changes in the firing rates, thresholds, and recruitment orders of single-motor units (SMUs) of the nonpainful, synergistic right anterior temporalis muscle during goal-directed isometric biting task performance.

METHODS: Twenty healthy volunteers received an infusion of hypertonic saline (HS; 5% sodium chloride) into the right masseter to produce pain intensity of 40 to 60 on a 100-mm visual analog scale (VAS). Isotonic saline (IS) infusion was a control. Standardized biting tasks were performed with an intraoral force transducer, and intramuscular electromyographic activity was recorded from the right anterior temporalis muscle. Tasks (slow and fast ramp biting tasks, two-step biting task) were performed in 3 blocks: baseline, HS infusion, and IS infusion. Across blocks, SMU thresholds and firing rates were statistically compared, and SMU recruitment sequences were qualitatively compared. Statistical significance was set at P < .05.

RESULTS: No significant differences (P > .05) were noted between HS and IS infusion blocks in thresholds or firing rates of anterior temporalis SMUs. Individual SMUs showed increases or decreases in thresholds or firing rates or changes in recruitment sequences mostly during HS compared to IS infusion.

CONCLUSION: The reorganization of SMU activity that has been suggested to occur in both painful and nonpainful agonist jaw muscles may involve not only recruitments and de-recruitments of SMUs, but may also extend to more subtle increases and/or decreases in firing rates, thresholds, and recruitment sequences of individual SMUs in the nonpainful synergistic muscles.

ABSTRACT

Previous empirical evidence suggests that the engagement in social interactions across different everyday contexts occurs in a manner highly responsive to a person’s social affiliation needs. As has been shown repeatedly, social engagement (as well as disengagement) can be predicted from earlier situational need states, implying that homeostatic principles underlie a person’s social affiliative behaviors. However, little is known about the role of emotion in these regulative processes. For this reason, the present exploratory study investigated the predictive role of state feelings of loneliness in subsequent engagement in social interaction. Since loneliness is conceptually associated with both the need to reaffiliate as well as self-protecting tendencies potentially hindering engagement in social contact, the study investigated the possibility of both increases and decreases in social contacts resulting from state feelings of loneliness. Adopting an experience sampling methodology (ESM), a sample of 65 participants was recruited from a local university and was followed for 14 days. Subjects were prompted several times a day to rate their feeling states and the quantity of social interactions, using a fixed interval assessment schedule. Statistical analyses using multilevel analysis indicated that state feelings of loneliness had complex quadratic effects upon subsequent social interaction, leading to both increases and decreases in subsequent social interaction. Moreover, these effects were contingent upon previous engagement in social interaction, implying spillover effects across social contexts that are conditionally mediated by feelings of loneliness. These findings clearly imply an important, albeit complex role of state feelings of loneliness in the regulation of social affiliation, both as a predictor and a consequence of social interaction. These exploratory findings are discussed against the background of methodological and conceptual limitations, and several recommendations for future studies are made.

ABSTRACT

This study was intended to explore and confirm the factorial structure and to analyze the psychometric properties of an instrument for university guidance and tutoring, apply it, and detect differences between sociodemographic variables. A total of 1,048 students from five universities in the province of Manabi (Ecuador) participated. The study was divided into two phases with differentiated samples. An exploratory phase, made up of 200 subjects (19.1%), and another confirmatory phase, made up of 848 (80.9%), where the questionnaire was also applied. The results supported the three-factor structure of the instrument called “Questionnaire for the Assessment of Guidance and Tutoring in Higher Education” (Q-AGT), with of a total of 21 items. The indices of goodness of fit, reliability and internal consistency of the model were considered satisfactory. The application of the questionnaire did not show statistically significant differences in the assessment of university guidance and tutoring between men and women, with a high value given by both sexes to the importance of tutoring, the demands and the competences of the teaching staff in the university. The differences were mainly found between universities and branches of knowledge. Among the main conclusions, what stands out is the achievement of a valid and reliable instrument to measure the development of guidance and tutoring in Latin American universities. This contributes to the assessment of university guidance and tutoring as a strategy for the integral development of the student- personally, academically and professionally- and as a possible protective factor against academic dropout.

ABSTRACT

Visceral leishmaniasis (VL) is one of the most prevalent parasitic diseases worldwide. In 2019, 97% of the total numbers of cases in Latin America were reported in Brazil. In São Paulo state, currently 17.6% of infected individuals live in the western region. To study this neglected disease on a regional scale, we describe the spread of VL in 45 municipalities of the Regional Network for Health Assistance11(RNHA11). Environmental, human VL (HVL), and canine VL (CVL) cases, Human Development Index, and Lutzomyia longipalpis databases were obtained from public agencies. Global Moran’s I index and local indicators of spatial association (LISA) statistics were used to identify spatial autocorrelation and to generate maps for the identification of VL clusters. On a local scale, we determined the spread of VL in the city of Teodoro Sampaio, part of the Pontal of Paranapanema. In Teodoro Sampaio, monthly peri-domicile sand fly collection; ELISA, IFAT and Rapid Test serological CVL; and ELISA HVL serum surveys were carried out. In RNHA11 from 2000 to 2018, Lu. longipalpis was found in 77.8%, CVL in 69%, and HVL in 42.2% of the 45 municipalities, and 537 individuals were notified with HVL. Dispersion occurred from the epicenter in the north to Teodoro Sampaio, in the south, where Lu. longipalpis and CVL were found in 2010, HVL in 2018, and critical hotspots of CVL were found in the periphery. Moran’s Global Index showed a weak but statistically significant spatial autocorrelation related to cases of CVL (I = 0.2572), and 11 municipalities were identified as priority areas for implementing surveillance and control actions. In RNHA11, a complex array of socioeconomic and environmental factors may be fueling the epidemic and sustaining endemic transmission of VL, adding to the study of a neglected disease in a region of São Paulo, Brazil.

ABSTRACT

The instability of optical phase chaos synchronization between semiconductor lasers under master-slave open-loop configuration is investigated. The phase difference between the master and slave lasers is obtained and analyzed in experiment by heterodyne detection and Hilbert transform, and in simulation by solving the rate equations. The results show that the phase difference only maintains in a short duration time and then jumps to another value. A statistical analysis shows that both duration time and jumping values are random, proving that the phase chaos synchronization is unstable. A theoretical analysis shows that the instability of phase synchronization is caused by the jumping of the external cavity mode in the master laser.

ABSTRACT

BACKGROUND: Smart devices (SDs) are widely used among adolescents. Numerous studies have recommended further research on this topic to find out the prevalence of SD overuse among school students and to what extent this is associated with psychological distress. The present study aimed to investigate the pattern of SD use among secondary and high school students in the state of Kuwait, as well as the possible associations with psychological problems, weight, physical activity, and school performance.

MATERIALS AND METHODS: The correlational study design aimed to survey students from public schools by using a questionnaire and valid instruments, which included: Smartphone Addiction Scale-Short Version (SAS-SV) and Stress, Anxiety, and Depression Scale-(DASS-21). Pearson’s correlation coefficient, t-tests, one-way ANOVA were applied to find associations or significant differences between the categorical variables, in which p < 0.05 was considered statistically significant.

RESULTS: The study included 1,993 students from secondary schools (48.9%) and high schools (51.1%), of which 47.5% were male and 52.5% were female. There were significant statistical differences in the pattern of use of SDs, addiction to SD use, stress, anxiety, and depression according to gender, school type, school performance, and sport engagement. In addition, there were positive correlations between students’ addiction to SD use and stress, anxiety, and depression.

CONCLUSIONS: The findings suggest that excessive SD use is associated with addiction among secondary and high school students. In addition, levels of stress, anxiety, and depression differ according to the number of hours of SD use. Strategies should be developed at the community and school levels to avoid the overuse of SDs among school-aged students.
