Introduction: Cigarette smoking is a prime risk factor for cardiovascular morbidity and mortality. Chronic smoking results in autonomic dysfunction leading to increased cardiovascular risk in smokers. The present study was planned to study the effect of smoking on the Cardiovascular Autonomic Functions among smokers. Materials and Methods: Fifty male subjects who were in the age group of 25 to 45 years. They were grouped into 25 smokers and 25 non-smokers. The participant subjects were selected among the staff members, residents and the patients from the routine OPD in SVIMS. Prior to study, they were informed about the procedure and the purpose of the study tests and written consents were obtained from them. The Cardiovascular Autonomic Function Tests were assessed by using a POLYGRAPH which was available in the department. Results and Conclusion: After applying the ‘t’-test for the difference between the two sample means, it was observed that there was a highly significant difference between the mean values of the BMI(i.e.p<0.01) and the para-sympathetic function tests among the smokers and the non – smokers(i.e.p<0.00). The Resting Heart Rate had significantly increased and the Deep breathing difference, the postural tachycardial index (Response to standing) and the Valsalva Ratio had significantly decreased in the smokers as compared to those in the non – smokers. After applying the ‘t’-test for the difference between the two sample means, it was observed that there was no significant difference between the mean values of the Postural hypotension test (i.e. p>0.05) and that there was a highly significant difference between the mean values of the Sustained handgrip test in the smokers and the non – smokers (i.e. p<0.00). KEY WORDS: Cardiovascular autonomic function tests, Smoking, Resting heart rate.

ABSTRACT Introduction In recent years, the various health benefits of meditation have been acknowledged by the scientific community as well as by the public. Apart from its physiological benefits, it can also improve the psychological and spiritual well-being. A case–control study was planned to investigate the effect of Rajyoga Meditation on cardiovascular autonomic activity in meditators and nonmeditators. Materials and methods The study was conducted on 100 subjects, randomized into two groups: meditators (n = 50; age 35.80 ± 7.69 years) and nonmeditators (n = 50; age 36.76 ± 6.38 years). The meditator group practiced meditation for 30 minutes in the morning as well as in the evening. The control group did not practice any type of meditation or relaxation techniques. The cardiovascular parameters – heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP), and Valsalva maneuver tests – were performed in both the groups in the same environmental conditions. The data were compiled and analyzed using unpaired t test. Results The mean values of HR in meditators and the control group were 77.08 ± 5.39 and 80.68 ± 5.71 respectively, and the difference was statistically significant (p < 0.001). The mean values of SBP in meditators and nonmeditators were 124.60 ± 5.39 and 129.56 ± 4.30 mm Hg respectively, while those for DBP were 77.84 ± 4.65 and 80.80 ± 4.78 mm Hg respectively. The difference in both was statistically significant. In meditators, Valsalva ratio was 1.60 ± 0.20, while in nonmeditators, it was 1.33 ± 0.13, and the difference was highly significant. Conclusion Significant improvement is seen in physiological, cardiac, and parasympathetic parameters in Rajyoga meditators. A shift of the autonomic balance toward the parasympathetic side is seen. By purposefully energizing the parasympathetic system by meditation, we can combat the ill effects of stress and help heal many health conditions.

Background:Patient’s global assessment (PGA) is one important component of Boolean composite criteria for remission in treat with rheumatoid arthritis (RA). However, PGA no more than 10mm is sometimes obstacle to attain clinical remission. In recent few years, one opinion that PGA no more than 20mm may be comparable as no more than 10mm.Objectives:The aim of this study is to analyze how difference of these PGA level affect disease activity and daily activities in living, and evaluate which is optimal for the remission with Boolean remission criteria from real world setting.Methods:RA patients who were followed up for more than three years in the institute were picked up in the study. Each patient was monitored with tenderness joint count (TJC), swollen joint count (SJC), PGA, evaluator’s global assessment (EGA), serum C-reactive protein level (CRP), calculated disease activity score with simplified disease activity index(SDAI), Health Assessment Questionnaire Disability Index (HAQ-DI), and pain score using visual analog scale (PS-VAS) every consulted time from the first encounter (Baseline). Patients were classified according to achievement of Boolean remission criteria. Group 1: a patient group who attained Boolean remission wih TJC≦1, SJC≦1, CRP≦1mg/dl, and PGA≦1 (G-1), Group 2: a patient group who could not attained the Boolean remission used in the G-1 evaluation, but could attained another Boolean remission with TJC≦1, SJC≦1, CRP≦1mg/dl, and PGA≦2 (G-2), and Group 3: a patient group who could not attain Boolean remission for neither criterion.Mean values of measured parameters at Baseline and after the Baseline were compared statistically with Student T-test. Mean values of the same parameters in the G-1 and G-2 at the time of attain Boolean remission for each criteria, mean values of each of these parameters thereafter, and changes of these parameters were compared statistically with Student T-test.Results:A total of 438 patients 385 in the G-1 group, 16 in the G-2 group, and 37 in the G-3 group, were recruited. In parameters at Baseline, level of TJC, SJC, PGA, EGA, SDAI, and HAQ-DI in the G-1 was significantly lower than in the G-3, whereas no significant differences in any parameters demonstrated between in the G-2 and G-3. Level of HAQ-DI, and PS-VAS after Baseline in the G-1 was lower than in the G-3, whereas no significant difference of these parameters after Baseline demonstrated between in the G-2 and G-3. TJC, SJC, PGA, and EGA demonstrated significant less level in the G-1 than in the other two groups. The mean SDAI score at the time of first achievement of Boolean remission in the G-1 and G-2 were 1.08 and 2.57, respectively. The mean value of SDAI score after remission in the G-1 and G-2 were 3.35 and 6.44, respectively. These values and PS-VAS including change of the SDAI score demonstrated significant difference between the two groups (p<0.01), whereas HAQ-DI in the two groups demonstrated no significant difference.Conclusion:These results suggested that setting PGA as no more than 10mm should be reasonable for the evaluation of clinical remission with the Boolean criteria.Disclosure of Interests:None declared

This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I) or not (II) apical patency during canal preparation and filling removal technique (manual - M or ProTaper system - PT). After filling material removal, each specimen of each group had the apical foramen cleaned by sizes 15, 20 and 25 instruments, generating 12 subgroups: GIM15, GIM20, GIM25, GIIM15, GIIM20, GIIM25, GIPT15, GIPT20, GIPT25, GIIPT15, GIIPT20 and GIIPT25. Extruded filling debris was collected by a Milipore filtration system, an HV-durapore, 0.45 µm pore filter with a 25 mm diameter. The filters were weighed before and after the collection on an analytical scale (10–5 g), and the difference was calculated. The mean weight of extruded filling debris was analyzed statistically by Kruskal-Wallis and Friedman ANOVA tests (α=0.05). The mean values found in the groups (in mg) were: GIM (0.95±0.94), GIIM (0.47±0.62), GIPT (0.30±0.31) and GIIPT (0.32±0.44). There was no statistically significant difference among any of the groups or subgroups (p>0.05). ProTaper provided the smallest amount of extruded filling material, regardless of presence or absence of apical patency, followed by manual technique, without and with apical patency. Additional amounts of debris were collected during cleaning of the apical foramen, regardless of the instrument, presence/absence of patency or root filling removal technique.

The purpose of the present study is to investigate the effect of explicit affective strategy instruction on the speaking performance of Freshmen English majors at Faculty of Education, Suez University, Egypt. The design of the study is a pre-post quasi experimental one. The instrument is a pre/post speaking performance test (designed by the researcher). Participants were eighty Freshmen English majors, randomly divided into two groups: a control group (N=40) and an experimental one (N=40). During the experiment, the experimental group was explicitly taught some affective strategies (lowering anxiety, encouraging yourself and monitoring emotions) while the control group was taught using the traditional method. All participants were tested using the pre/post speaking performance test before and after the intervention. The difference between the post test&rsquo;s mean scores of the control and experimental groups were calculated using Independent Samples t-test and the difference in the mean scores between the pre- and post tests of speaking performance was calculated for each group separately using Paired Samples t-test. A significant difference was found between the post test&rsquo;s mean scores of the control and the experimental groups in favor of the experimental group. Moreover, a significant difference was found between the mean scores of the pre and post test of the experimental group in favor of the post test. It was concluded that participants&rsquo; level of speaking performance significantly improved after receiving the explicit affective strategy instruction.

There is a lack of accurate three-dimensional studies to locate malar prominence for specified population, this study aims to locate the malar prominence using stable landmarks using CBCT. To derive a novel method to accurately locate the malar prominence and to assess and compare the malar prominence between males and females among Bangalore population using 3D CBCT study. All CBCT scans of study subjects belong to Bangalore population were collected from the pre-existing data available in Radiology imaging Solutions (CBCT centre), Bangalore during the period of September 10th to October 10th 2020. This is a descriptive study. A total of 42 subjects including 21 Males and 21 females were assessed using full skull CBCT scans which were converted to DICOM format and reconstructed into 3D images using NEMOCEPH 3D software. Landmarks used to locate the malar prominence were Fzs, Z, Zm and Ans. The intersection of these landmarks is considered to be as constructed maxillozygion(My). For the accuracy of the constructed Maxillozygion point (My), the distance between the actual Maxillozygion (Mzy) and constructed Maxillozygion (My) is measured and calculated between left and right halves of males and females. Three Orthogonal planes constructed were Midsagittal, Axial and Coronal Planes and the linear measurements with reference to all three reference planes in both the groups are measured. Student paired t- Test, Independent Student t Test, Mann Whitney Test. The mean distance from Mzy and my between right and left half of the face was compared using student paired t- Test. There is no significant difference (p=0.35).The mean values of the constructed anatomical landmark (maxillozygion) coordinated to three orthogonal planes between right and left sides of the face is compared using student paired T test and for both the genders (males and females) was compared using Independent Student t Test, and it is significantly higher in males as compared to females and it is statistically significant at (p=0.01). The location of malar prominence using CBCT by a novel method for Bangalore population is found which can be helpful in diagnosis and treatment planning for malar augmentation, camouflage treatment in subjects with midface deficiencies.

OBJECTIVE: Tea has been considered a healthy alternative to other industrialized beverages. The objective of this study was to assess the erosive potential of teas commercially available in Brazil by pH and titratable acidity measures. METHODS: Eighteen teas available in Brazilian market were selected for this study (read to drink and brewed tea), and a brand of yerba mate (Ilex paraguariensis). Each product was analyzed for pH and titratable acidity. For comparison between different kinds of teas, the Student t test was used. RESULTS: The mean pH values for ready to drink teas ranged between 2.89 and 4.03, while for the brewed teas and yerba mate the values ranged between 6.75 and 7.89. The difference between the two groups was significant (p < 0.05). Regarding titratable acidity, the ready to drink teas showed mean values ranging between 3.77 ml and 12.68 ml. Brewed teas (including yerba mate) were not tested for titratable acidity because their pH values were greater than 7.0. CONCLUSION: Among the teas commercially available, ready to drink teas have lower pH values and higher titratable acidity compared to other teas. It suggests that they have an erosive potential.

Vergence Eye Movement

Background: Proximal vergence is defined as a vergence eye movement subtype driven by an “awareness of nearness”. The purpose of this experiment was to compare values of proximal vergence calculated with and without measures of accommodation to assess the clinical utility of each measurement method. Methods: Thirteen participants between the ages of 22 and 37 (mean = 28.5 ± 4.5 years) were enrolled. The distance and near heterophoria were measured using the Modified Thorington technique. The near heterophoria was measured under three randomized viewing conditions (no lenses, +1.00D lenses, +2.50D lenses). Refractive error was measured with an autorefractor. Proximal vergence was calculated as the difference in calculated (far-near) and gradient (+1.00) stimulus AC/A ratios (stimulus AC/A differencing method), the difference in calculated and gradient response AC/A ratios (response AC/A differencing method), and the change in vergence from distance to near with the +2.50D lenses (uncorrected +2.50D method). This latter value was also corrected for any active accommodation with +2.50D lenses (corrected +2.50D method). Results: The mean proximal vergence values (Δ) were 7.82 ± 5.98 (stimulus AC/A differencing method), 8.29 ± 3.30 (response AC/A differencing method), 6.23 ± 3.52 (uncorrected +2.50D method), and 5.13 ± 2.98 (corrected +2.50D method). The only comparison that showed both a significant correlation (p<0.05) and a non-significant difference from the paired t-test (p>0.05) was that between the stimulus AC/A differencing method and the uncorrected +2.50D method. Conclusions: When response accommodation was accounted for, differences occurred in the mean proximal values obtained with the various methods. The means of the methods most likely to be used clinically (stimulus AC/A differencing method and uncorrected +2.50D method) were similar, although some individuals demonstrated significant differences between these methods.

Object Despite lower failure and infection rates compared with shunt placement, it has not been known whether endoscopic third ventriculostomy/choroid plexus cauterization (ETV/CPC) might be inferior in regard to neurocognitive development. This study is the first to describe neurocognitive outcome and ventricle volume in infants with hydrocephalus due to myelomeningocele that was treated primarily by ETV/CPC. Methods The modified Bayley Scales of Infant Development (BSID-III) test was administered to 93 children with spina bifida who were 5–52 months of age. Fifty-five of these children had been treated by ETV/CPC, 19 received ventriculoperitoneal (VP) shunts, and 19 had required no treatment for hydrocephalus. Raw scores were converted to scaled scores for comparison with age-corrected norms. Ventricular volume was assessed by frontal/occipital horn ratio (FOR) calculated from late postoperative CT scans. The mean values between and among groups of patients were compared using independent samples t-test and ANOVA. The comparison of mean values to population normal means was performed using the single-sample t-test. Linear regression analyses were performed using BSID scores as the dependent variables, with treatment group and ventricular size (FOR) as the independent variables. Probability values < 0.05 were considered significant. Results . There was no significant difference in mean age at assessment among groups (p = 0.8). The mean scale scores for untreated patients were no different from normal (all p > 0.27) in all portions of the BSID (excluding gross motor), and were generally significantly better than those for both VP shunt–treated and ETV/CPC groups. The ETV/ CPC-treated patients had nonsignificantly better mean scores than patients treated with VP shunts in all portions of the BSID (all p > 0.06), except receptive communication, which was significantly better for the ETV/CPC group (p = 0.02). The mean FOR was similar among groups, with no significant difference between the untreated group and either the VP shunt or ETV/CPC groups. The FOR did not correlate with performance. Conclusions The ETV/CPC and VP shunt groups had similar neurocognitive outcomes. Neurocognitive outcomes for infants not requiring treatment for hydrocephalus were normal and significantly better than in those requiring treatment. The mean ventricular volume was similar among all 3 groups, and significantly larger than normal. There was no association between FOR and performance. Stable mild-to-moderate ventriculomegaly alone should not trigger intervention in asymptomatic infants with spina bifida.
