Abstract Objective: To compare the dentofacial effects of mandibular incisor intrusion using mini-implants with those of a conventional incisor intrusion mechanic, the utility arch. Materials and Methods: Twenty-six deep-bite patients were enrolled to one of the two groups. In group 1 the mandibular incisors were intruded using a 0.16 × 0.22–inch stainless-steel segmental wire connected to two mini-implants. In group 2 the mandibular incisor intrusion was performed using a conventional utility arch. Conventional lateral cephalometric radiographs were taken at pretreatment and at the end of intrusion. Thirty landmarks were identified to measure 23 linear and 20 angular measurements. Intragroup comparisons were made using a paired t-test or a Wilcoxon test. Intergroup comparisons were made using a Student's t-test or a Mann-Whitney U-test. Results: The duration of intrusion was 5 months for group 1 and 4 months for group 2. In the implant group, the mean amount of change was 0.4 mm/mo for the incisor tip and 0.3 mm/mo for the center of resistance, and in the utility arch group, the mean amount of change was 0.25 mm/mo for the incisor tip and 0.2 mm/mo for the center of resistance. The mandibular incisors showed an average protrusion of 7° in the implant group and 8° in the utility arch group. Conclusions: Incisor intrusion that was achieved using an implant-supported segmented archwire was no different than the movement achieved with a conventional intrusion utility arch. The only difference between the two methods was in the molar movement.

ABSTRACT Objective To assess and compare the effects produced in the maxillary dental arch by means of Connecticut intrusion arch (CIA) with or without a cinch back on the distal end of the tube of the first molars. Materials and Methods This study included 44 patients with a mean age of 13.1 ± 1.8 years treated for deep bite with a CIA randomly divided into two groups: group 1 (G1), 22 patients with initial mean age of 12.72 ± 1.74 years treated with the CIA in the upper arch without a cinch back on the distal surface of the tube of the first molars, and group 2 (G2), 22 patients with an initial mean age of 13.67 ± 2.03 years treated with the CIA with a cinch back. Lateral cephalograms were available before treatment (T1) and after intrusion of maxillary incisors (T2). The mean treatment period was 5.5 ± 1.45 months. Intragroup and intergroup changes in the maxillary incisor and molar positions were analyzed by paired and independent t-tests associated with the Holm-Bonferroni correction method for multiple comparisons (P < .05). Results There were significant differences between groups in terms of maxillary incisor displacement. The maxillary incisors flared labially (2.17°) and proclined (1.68 mm) in group 1, whereas a palatal inclination (−1.99°) and retroclination (−1.13 mm) was observed in group 2. No significant differences were found for the molar positions between the groups. Conclusions The presence or absence of a distal bend in CIA affects incisor tipping and proclination during intrusion mechanics.

Background: Footwork training is important in coaching basic movements in badminton. This research aims to learn about the influence of footwork training on improving leg muscles strength. Methods: The study used a randomized pretest-posttest control group design. The participants consisted of 42 male badminton players of Universitas Pendidikan Ganesha, Bali, Indonesia, who split into two groups of footwork training (ten repetitions two sets (group 1) and five repetitions with four sets (group 2)). The coach gave the footwork exercise three times per week for 6 weeks to each group and measured the leg muscle strength using the dynamometer test. Results: The result of the within-group paired T-test before and after the training shows group 1 and group 2 (p<0.05). For group 1, the mean of leg muscle strength was 114.19±33.13 kg before the training and 183.19±33.56 kg after the training, with an increase of 60% (69 kg). On the other hand, for group 2, the mean score of leg muscle strength before the training was 113.05±31.30 kg and after the training was 141.10±34.91, with an increase of 25% (28 kg). The leg muscle strength difference between the groups before and after the training was tested using the independent T-test with a significant α=0.05. Comparing the differences of leg muscle strength for both the groups before the training was p= 0.90, and after the training was p=0.00. Conclusion: The conclusion is training badminton footwork ten repetition two sets better than five repetitions four sets to improve leg muscle strength.

Aim: Different procedures have been attempted to regenerate intrabony defects in periodontitis but complete regeneration is still a herculean feat. Nanoparticles could prove to be advantageous because of their small size and increased surface area. The aim was to evaluate the effectiveness of a chitosan nanohydrogel as a periodontal regenerative material in the management of intrabony defects. Materials and Methods: Twenty patients within the age group of 30 to 60 years with intrabony defects >3 mm and clinical attachment levels >5 mm were selected. They were divided randomly into two groups: group-1, which received only open flap debridement with bone graft and acted as control, and group-2, which received open flap debridement, bone graft mixed with a chitosan nanohydrogel, and acted as the test site. Clinical and radiographic measurements were recorded at baseline, three months, and six months. Intragroup comparison was done using a paired t-test and intergroup comparison was done using an unpaired t-test with the statistical value set at P < .05. Results: Chitosan hydrogel incorporated bone grafts showed improved bone regenerative potential. The mean reduction in clinical attachment level in group-2 (8.7 ± 0.6 to 1.6 ± 0.8) was significantly higher than that of group-1 (8.6 ± 0.5 to 2.4 ± 0.7). The mean reduction in probing depths in group-2 (test group) was significantly higher (8.3 ± 0.9 to 1.6 ± 0.8) when compared to group-1 (8 ± 0.8 to 2.3 ± 0.7). Significant amount of defect fill was obtained in both the groups from baseline to six-month period. Conclusion: Organic materials such as chitosan could have potential bone regenerative capacity.

BACKGROUND: Intrusion of maxillary incisors is the treatment of choice to correct deep bite problem in gummy smile patients. AIM: The objective of this study was to compare the effectiveness and efficiency of miniscrew-supported intrusion versus intrusion arch for treatment of deep bite.METHODS: The study sample consisted of 30 post pubertal patients (21 females and 9 males) with an age range from 17 to 29. They were divided into 2 groups (15 subjects in each group). Group 1 underwent maxillary incisor intrusion using miniscrews, and in group 2 intrusive arch was used. Pre and post-treatment lateral cephalometric x-rays and study models were made to evaluate the demo-skeletal effects. During the study period, no other intervention was attempted. Paired t-test was used to study the changes after treatment.RESULTS: The mean amount of overbite correction was 2.6 ± 0.8 (0.49 mm per month) in the miniscrew-supported intrusion group and 2.9 ± 0.8 (0.60 mm per month) in the intrusive arch group. No statistically significant difference was found in the extent of maxillary incisor intrusion between the two systems. The two intrusion systems were statistically different in the extent of incisor proclination, as an intrusive arch group tended to proline upper incisors more than miniscrews-supported intrusion group.CONCLUSION: Both systems successfully intruded the 4 maxillary incisors almost with no loss to the sagittal and vertical anchorage, although intrusive arch tended to proline upper incisors significantly.

 Objectives: Automatic devices based on oscillometric principle are widely used for the estimation of blood pressure (BP). Mercury sphygmomanometer mean systolic BP (MSBP) and its derived cuff pressure are the traditional mode of estimation which is a validated and authenticated procedure. Automated machines using oscillometric method are slowly replacing the conventional technique. This study was done to compare the BP recorded by the mercury sphygmomanometer MSBP and the automated technique using oscillometric method automated office BP (AOBP).Methods: Two hundred subjects aged 40–65 years with mid-arm circumference 27–34 cm were recruited. MSBP and AOBP were recorded adhering to guidelines given by the American Heart Association Joint National Committee. The subjects were divided into two groups as normotensive (Group 1) and hypertensive (Group 2), and statistical analysis was performed.Results: The mean systolic and diastolic pressures estimated by oscillometric method and sphygmomanometer were calculated and compared with each other by paired t-test separately for Groups 1 and 2. In mormotensives (Group 1), the mean systolic pressure MSBP was 114.21±7.5 mmHg and AOBP was 118.24±11.0 mmHg. The mean diastolic MSBP was 72.1±3.5 mmHg and AOBP was 76.4±1.2 mmHg. Subjects of Group 2 (hypertensive) showed mean systolic pressure MSBP of 144.42±18.5 mm Hg and AOBP of 159.74±22 mmHg. The mean diastolic MSBP was 87.2±9.5 mmHg and AOBP was 96.9±9.2 mmHg. In Group 1, the difference was statistically not significant, while in Group 2, comparison by paired t-test showed a mean difference of systolic pressure by 15.32±1.25 (p<0.005), and mean difference of diastolic pressure by 8.9±5.8 (p<0.005).Conclusion: Hence, we conclude that oscillometric pressure recordings by the automated device are closer to manual measurements in normotensives but showed a significant high value in hypertensives. We suggest caution in treating hypertensives with values derived from automated machines only.

ABSTRACT Objective:  To compare, through cone-beam computed tomography (CBCT), the root resorption and treatment efficiency of two different mini-implant-assisted modalities in intruding the maxillary incisors. Materials and Methods:  Thirty-two adults who had deep bite and elongated maxillary incisors were randomly allocated to two groups: anterior mini-implant group (AMG) and posterior mini-implant group (PMG). In the AMG, approximately 40 g of force was applied per side with elastic chains from mini-implants placed between the lateral incisors and canines and in the PMG, with beta-titanium wires from mini-implants placed between the second premolars and first molars. This study was conducted on CBCT scans taken before intrusion and after 4 months of intrusion. Data were analyzed by means of a paired t-test, independent t-test, and Pearson’s correlation test. Results:  One patient was excluded from the AMG due to mini-implant loosening. While the incisors showed a significant reduction in length and volume, this amount was greater in the AMG, especially in the central incisors (P &lt; .05). Together with the mean intrusion rates of 0.62 and 0.39 mm/mo in the AMG and PMG respectively, the center of resistance of the incisors showed distal movement with labial tipping; these changes were greater in the PMG (P &lt; .001). Volumetric root resorption was correlated with the amount of intrusion (P &lt; .05). Conclusions:  Intrusion anchoring from posterior mini-implants is preferred in cases of upright incisors, as the use of such mechanics directs the roots into the spongiosa where they undergo less root resorption and more labial tipping.

Abstract Background The prevalence of chronotropic incompetence (CI) in heart failure (HF) population is high and negatively impacts prognosis. In HF patients with an implanted cardiac resynchronisation therapy (CRT) device and severe CI, the effect of rate adaptive pacing on patient outcomes is unclear. Closed loop stimulation (CLS) based on cardiac impedance measurement may be an optimal method of heart rate adaptation according to metabolic need in HF patients with severe CI. Purpose This is the first study evaluating the effect of CLS on the established prognostic parameters assessed by the cardio-pulmonary exercise (CPX) testing and on quality of life (QoL) of the patients. Methods A randomised, controlled, double-blind and crossover pilot study has been performed in CRT patients with severe CI defined as the inability to achieve 70% of the age-predicted maximum heart rate (APMHR). After baseline assessment, patients were randomised to either DDD-CLS pacing (group 1) or DDD pacing at 40 bpm (group 2) for a 1-month period, followed by crossover for another month. At baseline and at 1- and 2-month follow-ups, a CPX was performed and QoL was assessed using the EQ-5D-5L questionnaire. The main endpoints were the effect of CLS on ventilatory efficiency (VE) slope (evaluated by an independent CPX expert), the responder rate defined as an improvement (decrease) of the VE slope by at least 5%, percentage of maximal predicted heart rate reserve (HRR) achieved, and QoL. Results Of the 36 patients enrolled in the study, 20 fulfilled the criterion for severe CI and entered the study follow-up (mean age 68.9±7.4 years, 70% men, LVEF=41.8±9.3%, 40%/60% NYHA class II/III). Full baseline and follow-up datasets were obtained in 17 patients. The mean VE slope and HRR at baseline were 34.4±4.4 and 49.6±23.8%, respectively, in group 1 (n=7) and 34.5±12.2 and 54.2±16.1% in group 2 (n=10). After completing the 2-month CPX, the mean difference between DDD-CLS and DDD-40 modes was −2.4±8.3 (group 1) and −1.2±3.5 (group 2) for VE slope, and 17.1±15.5% (group 1) and 8.7±18.8% (group 2) for HRR. Altogether, VE slope improved by −1.8±2.95 (p=0.31) in DDD-CLS versus DDD-40, and HRR improved by 12.9±8.8% (p=0.01). The VE slope decreased by ≥5% in 47% of patients (“responders to CLS”). The mean difference in the QoL between DDD-CLS and DDD-40 was 0.16±0.25 in group 1 and −0.01±0.05 in group 2, resulting in an overall increase by 0.08±0.08 in the DDD-CLS mode (p=0.13). Conclusion First results of the evaluation of the effectiveness of CLS in CRT patients with severe CI revealed that CLS generated an overall positive effect on well-established surrogate parameters for prognosis. About one half of the patients showed CLS response in terms of improved VE slope. In addition, CLS improved quality of life. Further clinical research is needed to identify predictors that can increase the responder rate and to confirm improvement in clinical outcomes.

Abstract Background A cytokine storm is life threatening for critically ill patients and is mainly caused by sepsis or severe trauma. In combination with supportive therapy, the cytokine adsorber Cytosorb® (CS) is increasingly used for the treatment of cytokine storm. However, it is questionable whether its use is actually beneficial in these patients. Methods Patients with an interleukin-6 (IL-6) > 10,000 pg/ml were retrospectively included between October 2014 and May 2020 and were divided into two groups (group 1: CS therapy; group 2: no CS therapy). Inclusion criteria were a regularly measured IL-6 and, for patients allocated to group 1, CS therapy for at least 90 min. A propensity score (PS) matching analysis with significant baseline differences as predictors (Simplified Acute Physiology Score (SAPS) II, extracorporeal membrane oxygenation, renal replacement therapy, IL-6, lactate and norepinephrine demand) was performed to compare both groups (adjustment tolerance: < 0.05; standardization tolerance: < 10%). U-test and Fisher’s-test were used for independent variables and the Wilcoxon test was used for dependent variables. Results In total, 143 patients were included in the initial evaluation (group 1: 38; group 2: 105). Nineteen comparable pairings could be formed (mean initial IL-6: 58,385 vs. 59,812 pg/ml; mean SAPS II: 77 vs. 75). There was a significant reduction in IL-6 in patients with (p < 0.001) and without CS treatment (p = 0.005). However, there was no significant difference (p = 0.708) in the median relative reduction in both groups (89% vs. 80%). Furthermore, there was no significant difference in the relative change in C-reactive protein, lactate, or norepinephrine demand in either group and the in-hospital mortality was similar between groups (73.7%). Conclusion Our study showed no difference in IL-6 reduction, hemodynamic stabilization, or mortality in patients with Cytosorb® treatment compared to a matched patient population.
