This work describes the educational game “Integrating Synapse, Muscle Contraction, and Autonomic Nervous System,” which was developed to assist students in understanding and integrating concepts related to the physiology of synapses, muscle contraction, and the autonomic nervous system. Analysis was made of the effect of the game on learning and the students’ opinions about it. Dentistry students were divided into control and game groups. They attended lectures about the topics, after which the control group students were submitted to a test, whereas the game group performed the game activity before undertaking the test. The mean score was significantly higher for the game group, compared with the control group ( P < 0.05). Pharmacy students also attended lectures about these topics; in the next class, the students performed a pretest and the activity with the educational game. After the game, a posttest was applied. The mean scores were significantly higher for the posttest than for the pretest ( P < 0.05). Students of medicine attended the lectures and performed the activity with the educational game, without the learning assessment. All of the students answered a question, using a 5-point Likert-type scale, concerning whether they thought the activity with the game was useful for learning. The mean scores obtained by the dentistry, pharmacy, and medicine students were 4.7 ± 0.6, 4.9 ± 0.3, and 4.3 ± 0.1, respectively. The educational game increased the learning of the undergraduate students, in agreement with their opinions of the strategy.

Introduction: Available data suggest that there is an association between endometriosis and a group of disorders including autonomic nervous system irregularities. A deeper understanding of relationship between endometriosis and autonomic nervous system is needed as it may lead to novel discoveries on the causes or consequences of endometriosis. In this study, we analyzed the prevalence of migraine in patients with endometriosis. Methods: In this cross-sectional study, medical records of women were reviewed through January 2013 to December 2017. Women with laparoscopically proven endometriosis (n = 185) were compared with those without endometriosis (n = 168). The 3-item screening questions (ID Migraine™) test was used to screen migraine. Data were analyzed using SPSS v25 (IBM Corporation). The χ2 test was used for analyzing the nominal parameters and group comparisons. Pearson χ2 was used to study the association between endometriosis and migraine. Results: The mean age was 31.86 ± 4.49 years of the endometriosis group and 28.95 ± 5.11 years of the controls (p = 0.408). The two pre-screening questions of ID Migraine test were answered positively by 86 patients of the endometriosis group (75.4%) and by 53 patients of the control group (54.6%) (p = 0.001). Of these patients, 51 (44.7% of endometriosis group) and 26 (26.8% of control group) were diagnosed as having migraine using 3-item Migraine questionnaire (p = 0.007). Conclusion: This study showed that the prevalence of migraine was significantly higher in patients with endometriosis. Because there is a strong correlation, patients with endometriosis should be screened for headache and migraine to increase the benefits of care.

Abstract   Within the framework of the research into pathological conditions and syndromes associated with undifferentiated connective tissue dysplasia (UCTD), an emphasis needs to be placed on the changes in heart rhythm. In puberty, the severity of neurovegetative disorders caused by the presence of UCTD might increase manifold. The features of heart rate variability (HRV) in pubertal children against the background of UCTD have been studied insufficiently and require more detailed analysis. This study aims to assess heart rate variability and tone of the autonomic nervous system (ANS) in puberty-aged children with UCTD. Two groups of children were examined, with methods including electrocardiography and cardiointervalography. The main group consisted of 36 puberty-aged children with UCTD, the control group consisted of 30 healthy children. ANS tone was assessed based on the HRV. In the control group of children aged 11, the value of variation range (VR) was 0.18±0.4, mode amplitude (MA) 35.2±2.4, stress index (IN) 72.8±4.3, which corresponds to the state of vegetative balance. As the puberty progresses, the state of eutonia is replaced by the activation of the sympathetic division of the ANS, which becomes most pronounced at the age of 13 years. In the control group of children aged 13, the value of VR was 0.08±0.02, MA 61.7±2.1, SI 210.6±8.6, which corresponds to moderate sympathicotonia. By the end of puberty, in healthy children, the severity of sympathetic activation begins to decrease, and at the age of 15 years, vegetative balance is again observed. However, this pattern is violated in children with UCTD. Upon entering puberty, moderate activation of the sympathetic division of the ANS is already observed in children with UCTD. At the age of 11 years in this group, the value of VR is 0.06±0.02, MA 72.4±3.1, SI 211.2±8.6. At the age of 13, pronounced sympathicotonia is observed, which is confirmed by the values of VR - 0.04±0.01, MA 80.2±4.3 and SI 34.3±14.7. By the end of puberty in children with UCTD, in contrast to the control group, the analyzed parameters indicate not an equilibrium of the ANS, but the predominance of parasympathetic activation. The research provides an insight into heart rate variability in puberty-aged children with UCTD. It was established that healthy children enter puberty in a state of equilibrium of the autonomic nervous system, which in the middle of puberty is replaced by moderate sympathicotonia, and then returns to its original values. Children with the presence of UCTD enter puberty with moderately pronounced sympathicotonia, which gradually increases to pronounced values and is replaced by moderate vagotonia.

Background: Elevated blood pressure variability (BPV) in the days after acute stroke onset is associated with worse outcome. However, the mechanism of increased BPV remains unknown, but may be due to dysfunction of the autonomic nervous system, which can be measured by pupil response to a light stimulus. Methods: This is a retrospective study of 109 patients in a neurocritical care unit: 45 with acute ischemic stroke (AIS), 44 with intracerebral hemorrhage (ICH), and 20 with subarachnoid hemorrhage (SAH). The primary outcome is BPV, measured as standard deviation of SBP (SD), using all blood pressures from admission to 72 hours later. The primary predictors are pupillary light reflexes (PLR) from the same period, measured with a bedside pupilometer, the NPi-200. We used linear regression to evaluate the association between PLRs and BPV, and adjusted for patient age and gender. Results: The mean (SD) age was 60.7 (16.4) and 58.7% were male. The mean (SD) number of blood pressure and PLR measurements were 30.0 (9.0) and 10.4 (7.3). We found that parasympathetically mediated PLR measures were associated with BPV in AIS patients (Table 1), but no consistent pattern emerged in ICH or SAH patients (all p>0.05). The relationships between BPV and PLR for AIS patients were linear in nature (Figure 1), and were consistent with parasympathetic hypofunction in patients with the greatest BPV. Conclusions: Elevated BPV is associated with parasympathetic hypofunction, as measured by pupillary response to light, after acute ischemic, but not hemorrhagic, stroke. Further research is needed to better understand this relationship as it may represent a therapeutic target for BPV reduction.

Abstract Background Pectus excavatum (PE) negatively impacts psychological function, but its effect on autonomic nervous system (ANS) function has not been investigated. We evaluated ANS function following postural changes in patients with PE.Methods The participants were 14 healthy men (control group) and 20 men with PE (study group). Psychological function was assessed using the visual analog scale for pain, Brief Symptom Rating Scale-5, and Beck Depression Inventory-II. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). ANS regulation in response to postural change was measured in the supine position and immediately after sitting. All measurements were compared between the control and study groups at baseline and between the study groups before and after Nuss surgery.ResultsAt baseline, upon postural change, symptomatic activity increased in the control group (50.3% to 67.4%, p=0.035) but not in the study group (55.0% to 54.9%, p=0.654); parasympathetic activity decreased in the control group (49.7% to 32.6%, p=0.035) but not in the study group (45.1% to 45.1%, p=0.654); and overall ANS regulation increased in the control group (1.02 to 2.08, p=0.030) but not in the study group (1.22 to 1.22, p=0.322). In response to postural change after Nuss surgery in the study group, sympathetic activity increased (48.7% to 70.2%, p=0.005), parasympathetic activity decreased (51.3% to 29.8%, p=0.005), and overall ANS regulation increased (0.95 to 2.36, p=0.012).Conclusion ANS function in response to postural change is dysregulated in patients with PE, which improved after Nuss surgery.Trial registration: ClinicalTrials.gov, ID: NCT03346876, November 15, 2017, retrospectively registered,https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid=S0007KGI&selectaction=Edit&uid=U0003JZU&ts=2&cx=cstxeg

Background: The study was designed to identify value of structured viva (SV) as an assessment tool, to ascertain its correlation with unstructured viva (UV) and to find relationship between viva and theory examination results.Methods: This prospective and observational study was conducted on a total of 135 students of the 2nd professional MBBS. All students faced two viva sessions (SV and UV), each of 10 marks on same topics in general pharmacology and autonomic nervous system. Time limit per student was 10 minutes. SV was conducted on pre-validated, standardized cards (n=40) with 5 questions in each card and 0.5 marks of each question. By draw of lots to be performed by students themselves, each student was given 4 cards. One week prior to the viva, the theory examination of 40 marks on same topics was conducted.Results: The mean marks of all students in SV (3.46±1.44) were significantly lower (P <0.0001) than those of UV (4.61±2.02). There was significant less deviation of mean marks in all groups of SV (P <0.05). The mean percentage marks of SV (34.63±14.37%) had similarities with results of theory examination (34.67±10.49%) (P=0.9720), while the difference between mean percentage marks of UV (46.15±20.19%) and theory was statistically highly significant (P <0.0001).Conclusions: SV increases objectivity and reduces subjectivity as compared to UV because of similar pattern of questions, difficulty levels and standardised scoring system. SV provides an opportunity to measure how well students can apply knowledge. Thus, SV can be used for formative and summative assessment.
