AbstractObjectivesKapalbhathi Pranayam (Kapal = forehead; bhati = shining) is a breathing exercise that has been practiced to cleanse the frontal brain in traditional practices like yoga. Still, there exists a dearth of literature on the effect of Kapalbhathi pranayama on physiological systems. So this present study was carried out to find the immediate effect of “kapalbhathi Pranayam” practice for the period of 5 min on cardiac autonomic function among the healthy volunteers.Materials and methodsApparently 50 healthy volunteers includes both sex were participated. They were randomly divided into Pranayama (n−25) and control (n−25) group. Pranayama group was practiced kapalbhathi pranayama 5 min (5 cycles) and control group was allowed to do normal breathing (12–16 breath/min). Lead II ECG was recorded for 5 min using simple AD converter before, immediately after practice and 20 min of recovery period.ResultsOne way Analysis of variance (ANOVA) followed by post hoc test was done using R statistical software. There was a significant (p < 0.05) parasympathetic withdrawal (Root Mean Square of the Successive Differences (RMSSD) – p < 0.04 and HF n.u – p < 0.05) was found in the pranayama group immediately after practice and its was changed to parasympathetic domination (RMSSD – p < 0.04 and HF n.u – p < 0.05) after 20 min of recovery period.ConclusionThe present study suggested that though there was parasympathetic withdrawal immediately after practicing kapalbhathi pranayama, 20 min after the recovery period showed a parasympathetic domination in the pranayama group subjects. However, further studies are required to warrant the findings of this study.

Background. Cardiovascular system recovery after physical activity with explosive exercises is essential for cardiovascular pathology prevention. The efficiency of short-term biofeedback training (BFB training) in such conditions in adolescents have not been studied earlier. Objective. Our aim was to study the effect of BFB training on cardiovascular rehabilitation after speed and power training in adolescents according to general heart rate variability (HRV) spectrum total power parameter. Methods. The research has included healthy eighth-grade students (14–15 years old boys) from regular school. Inclusion in experimental and control groups was regulated by researches. Such indicators as total power (TP) of HRV spectrum, tension index (TI), systolic and diastolic arterial blood pressure (ABP), heart rate (HR) were registered initially, after three standing long jumps with double take-off and after recovery. All members of experimental group performed BFB training in order to increase TP (3 min) during recovery period. Members of control group were resting. Results. Initially all members of experimental (n = 17) and control (n = 10) groups were compared on age, height, weight and TP, TI, ABP and HR indicators. The TP level in boys of experimental group was higher than in control group during recovery period after BFB training: 3.22 (1.96; 6.13) against 1.36 (1.15; 1.84) X 1000 ms2 respectively (р = 0.041). There were no differences in TI, ABP and HR levels between two groups during recovery period. Conclusion. Implementation of short-term BFB training according to general HRV spectrum total power parameter in 14–15 years old boys after speed and power training perpetuates vagal impact on heart rate during recovery period.

Introduction: Regular practice of slow breathing technique shows improvement in the cardio respiratory functions.  it is well known to decrease the effect of stress which, in turn, improves the physical and mental health of an individual. Objectives: To assess the effect of slow breathing exercise practice on anthropometric parameters in healthy volunteers. Materials and Methods: A total of 60 young, healthy volunteers of both genders participated in this study. The subjects were allocated to the study group (n = 30) and control group (n = 30) based on simple random technique. Slow breathing exercise training was given to the study group for 20 minutes daily in two sessions for 12 weeks. Heights, weight, body mass index (BMI), were recorded at the start of the study and after 12 weeks in both the groups. Comparison between the study group and control group was done by Student’s unpaired t-test. P < 0.05 was considered as statistically significant. Results: The average age of the study group and control group participants was 19.7 ± 1.7 years and 19.4 ± 1.9 years, respectively. BMI was significantly decreased in the study group from 21.72 ± 4.12 to 19.56 ± 3.92 (P < 0.05). There was a trend toward decrease in the waist–hip ratio from 0.78 ± 0.62 to 0.74 ± 0.58 (P > 0.05) which was not statistically significant. Conclusion: Slow breathing exercise training improve the anthropometric parameters in the study group. This indicates that regular, long-term slow breathing exercise training helps in weight reduction among the obese population.

SUMMARY Objective: To compare the effect of hydrofluoric acid (HF) vs self-etching ceramic primer on resin cement microshear bond strength (μSBS) and ultramorphology of lithium disilicate (LD) ceramic. Methods and Materials: LD (IPS e.max CAD, Ivoclar Vivadent) blocks (14×4×2 mm3) were polished to 1200 grit and assigned to nine groups (n=5): CON: control, no LD surface treatment; IVO: 5.0% HF (IPS Ceramic Etching Gel, Ivoclar Vivadent); VIT: 5.0% HF (Vita Ceramics Etch, VITA Zahnfabrik); FGM: 5.0% HF (Condac Porcelana, FGM); ULT: 9.0% HF (Porcelain Etch, Ultradent); PRM: 9.6% HF (Premier Porcelain Etch Gel, Premier); BIS: 9.5% HF (Porcelain Etchant, Bisco Inc); DEN: 10.0% HF (Condicionador de Porcelanas, Dentsply Brazil); and MEP: self-etching ceramic primer (Monobond Etch & Prime, Ivoclar Vivadent). For all HF groups and control, an MDP-containing silane solution (MB+, Monobond Plus, Ivoclar Vivadent) was applied on rinsing the HF gel and air drying. Three transparent matrices for each specimen were filled with light-cured resin cement (Variolink Veneer, Ivoclar Vivadent). After storage in water for 48 hours at 37°C, specimens were tested in shear mode to measure μSBS. Mode of failure was analyzed at 50×. Statistical analysis included one-way analysis of variance and the Duncan post hoc test (α=0.05). Thirty-six additional LD specimens were assigned to the same experimental groups (n=4) and observed under a field-emission scanning electron microscope (FESEM) at magnifications ranging from 10,000× to 100,000×. Results: IVO resulted in statistically higher mean μSBS than all the other groups. MEP resulted in statistically lower μSBS than all HF groups. The failure mode for MEP was predominantly adhesive. The most frequent failure mode for the HF groups was mixed. CON resulted in 100% pretesting failures. For FESEM, no retentive pattern was observed for CON specimens. MEP resulted in the least pronounced etching pattern, few areas around crystals exhibited a slight increase in retention pattern compared to the control group. All HF gels created microporosities on the LD surface with distinct etching patterns. VIT and DEN resulted in an LD ultramorphology that suggested overetching. Conclusions: HF etching followed by a silane solution resulted in higher bond strengths than a self-etching ceramic primer. Some HF gels may cause overetching of the LD intaglio surface.

INTRODUCTION: The enhancement of nurses’ risk perception plays a significant role in their preparedness during disasters and emergencies. Therefore, this study aimed to investigate the effect of educational workshops on disaster risk perception in nurses METHODS: This randomized controlled field trial study included 62 nurses working at Razi Hospital, Birjand, Iran. The participants were divided into intervention and control groups. The intervention group was then requested to participate in a one-day intensive educational workshop based on the current national standards. The workshop content included a combination of lecturing methods, round-table exercises, and film display. The data were collected using the demographic characteristic form and researcher-made questionnaires measuring the nurses’ risk perception during disasters and emergencies. Subsequently, the data were analyzed using independent t-test, repeated measures analysis, and Bonferroni post hoc tests. FINDINGS: The mean total score of risk perception were significantly higher in the intervention group before, immediately, and two months after the workshop session, compared to those in the control group (P˂0.001). CONCLUSION: The implementation of nurses’ national preparation program during disasters and emergencies can result in an increase in the nurses’ risk perception during these events. Therefore, regarding the importance of nurses’ preparedness in confrontation with disasters and emergencies, it seems necessary to integrate the National Preparedness Program into the educational programs immediately after recruitment and in the form of in-service courses.

Abstract BackgroundDue to numerous complications of an abnormal shape of the spine, it is extremely important to systematically monitor its shape. Precise and routine method of measurement enables comparison of the scores obtained over time and possible early intervention in order to avoid complications.The aim of the work is to present the pattern for monitoring changes in the shape of the spine in children with postural deformities.MethodsThe study group (n = 211) consisted of the patients with diagnosed shape of the spine deformity, who underwent a four-month therapy, supervised by a physiotherapist. The control group (n = 101) were the children with no shape of spine deformity.The children in the study group underwent a three-dimensional computer analysis of the shape of the spine. The DIERS test was performed in both groups (study and control). In the study group it was performed four times. It involved the measurement of seven parameters enabling a complete assessment of body posture.ResultsStatistically significant scores of the Friedman test for imbalance, pelvic tilt, kyphosis angle, lordosis angle, and lateral deviation were observed. Therefore, a series of post-hoc analyzes were performed using Dunn-Bonferroni tests. It was observed that changes in individual parameters analyzed in the authors' study come up at a different pace.ConclusionsDetailed monitoring of the parameters describing the position of the spine makes it possible to control the course of the treatment process of patients with disorders of the position of the spine. The dynamics of changes taking place within the spine position varies for the individual parameters analyzed.

Introduction: Radiofrequency catheter ablation of atrial fibrillation is performed under fluoroscopic guidance and therefore carries radiation risk exposure for the both the patient and the operator. Three-dimensional mapping systems and newer technologies to allow non-fluoroscopic catheter visualization together with intracardiac echo have reduced but not abolished the fluoroscopy exposure. We aim to demonstrate the feasibility, the safety and the efficacy of catheter ablation for atrial fibrillation without the use of fluoroscopy. Methods: A totally fluoro-less approach was developed for AF ablation at our Institution. 94 consecutive AF patients underwent zero fluoroscopy catheter ablation for atrial fibrillation. In the zero fluoroscopy cases, the fluoroscopy arm was kept far away from the patient table. Access including double trans-septal, mapping with the Carto 3 system and ablation were all performed without fluoroscopy with the use of ICE and the Carto 3 system. These 94 patients were compared with 94 control patients matched for age, sex and type of AF who underwent AF ablation by the same operator with the use of fluoroscopy. Results: Baseline characteristics were similar between fluoroless (N=94, Age=64.5 ± 10.1, 75.5% male, 48% paroxysmal) and control (N=94, Age=65.1 ± 9.9, 72.3% male, 50% paroxysmal) group. Non-PV triggers were detected and ablated in 51 (54.3%) and 56 (59.6%) patients in fluoroless and control group respectively (p=0.5). Average fluoro time in control group was 10.1 ± 4.7 minutes. Procedure duration was comparable (120.4 ± 25.8 vs. 122.2 ± 28.7, p =0.6). After the short term median follow-up of 4.5 (4 – 6.5) months, 10 (10.6 %) patients in flourless and 9 (9.6%) patients in control group experienced recurrences (p=0.8).One pericardial effusion requiring pericardiocenteis occurred in the fluoroless group. Conclusions: Our series show that zero fluoroscopy ablation of atrial fibrillation with the use of newer technologies is feasible, safe and efficacious at the short term follow up. Importantly in our series the double transeptal was performed without fluoroscopy and the ablation was not limited to the pulmonary veins only but included ablation of the posterior wall, the coronary sinus and the left atrial appendage.

ABSTRACT Objectives To examine the relationship between mandibular volume and craniofacial morphology in patients with cleft lip and palate using cone beam computed tomography (CBCT) and to compare these findings with control (noncleft) patients undergoing CBCT for other purposes during the deciduous dentition period. Materials and Methods Eighty-four patients were categorized into the unilateral cleft lip and alveolus (UCLA) group (n = 25; mean age, 4.60 ± 0.40 years), unilateral cleft lip and palate (UCLP) group (n = 23; mean age, 4.52 ± 0.39 years), bilateral cleft lip and palate (BCLP) group (n = 22; mean age, 4.54 ± 0.37 years), and control group without cleft (n = 14; mean age, 5.19 ± 0.52 years). Mandibular volume and craniofacial cephalometric measurements were obtained using CBCT. All measurements were assessed by analysis of covariance (ANCOVA) using Bonferroni post hoc pairwise comparison tests. Results ANCOVA revealed no statistically significant differences in mandibular volume among the groups. SNA° and ANB° were significantly larger in the UCLA and BCLP groups than in the control group. SN-MP° was smallest in the UCLA group. Co-A in the UCLP group was shorter than in the UCLA and BCLP groups. Go-Gn was shortest in the UCLP and BCLP groups compared with the control group. Conclusions Three-dimensional evaluation of craniofacial morphology using CBCT can provide valuable information on malocclusion and other dentoskeletal problems among patients with CLP.

Background In severe peritoneal dialysis (PD)-related peritonitis, patients’ response to antibiotic can be poor. We postulated that adjunctive lavage may improve the outcome in severe cases by enhancing the removal of bacteria and inflammatory cells from the peritoneum. Methods Severe PD peritonitis was defined as poor clinical response to empirical cefazolin/ceftazidime and a PD effluent (PDE) leukocyte count > 1,090/mm3 on day 3. Enrolled patients were randomized into either the lavage group ( n = 20) or control group ( n = 20). In the lavage group, continuous lavage by an automated PD machine from day 3 to 5 or 6 was performed, whereas the usual PD schedule was maintained in the control group. The primary outcome was treatment success. Post hoc analysis was also performed to compare the outcome between subgroups with different severity. Results Baseline parameters were similar in the lavage and control groups, including PDE leukocyte count on day 3 (4,871/mm3 vs 4,143/mm3, p = 0.46). Treatment success rates were high in both groups (75% vs 70%, p = 0.72). C-reactive protein (CRP) on day 3 was found to be the only predictor of treatment failure and was used to stratify all patients into tertiles of severity. Whilst a significant decline in treatment success was evident across the tertiles of increasing CRP in the control group (100% vs 85.7% vs 28.6%, p = 0.005), treatment success was relatively maintained in the lavage group (85.7% vs 71.4% vs 66.7%, p = 0.43). Conclusions Adjunctive lavage did not improve the overall outcome, although it may be beneficial for the more severe peritonitis patients who have high CRP.
