The PVA hydrogel with high-transparence has been prepared, the 1DMSO/2H2O network structure and the transparent mechanism were also explored.

It is documented that exercise can increase serum cardiac troponins in adults and adolescents; however, there is a lack of related studies concerning the release of cardiac troponins in children. This study investigated the influence of table tennis training on cardiac biomarkers in children. Twenty-eight male children performed six 10-min forehand exercise sessions with 5-min recovery intervals. Serum cardiac troponin T (cTnT) and I (cTnI), and creatinine kinase isoenzyme MB (CK-MB) were assessed before exercise, immediately after the last 10 min of exercise (PEI), 4 h post-exercise (PE4), 24 h post-exercise (PE24), and 48 h post-exercise (PE48). Cardiac function was measured using an ultrasound system (GE Vivid7 Dimension) at rest state. Serum cTnT, cTnI, and CK-MB were significantly elevated from the PEI sample point, and returned to baseline at the PE48 sample point in children. Serum cTnT in four (14.29%), nine (32.14%), and two (7.14%) subjects at the PEI, PE4, and PE24 sample points, respectively, exceeded the cutoff for myocardial injury. At the PE4 sample point, cTnT in five subjects (17.86%) exceeded the cutoff for acute myocardial infarction. Serum cTnI in two (14.29%), seven (25%), and two (7.14 %) subjects at the PEI, PE4, and PE24 timepoints, respectively, exceeded the cutoff for myocardial injury. cTnI in two subjects (7.14%) exceeded the cutoff for acute myocardial infarction at the PE4 timepoint in children. Repeated bouts of table tennis forehand training can significantly increase the release of serum cardiac troponins in some children.

The range of motion increased significantly in all patients. Flexion improved from a mean of 51° preoperation to a mean of 100° at discharge, and the average extension loss improved from 10° to 3° (p < 0.000). The average knee score, according to the Hospital for Special Surgery system, improved from 62 points preoperatively to 77 points at discharge, and 91 points at final follow-up (p < 0.000). All the patients were satisfied with the final ROM gain.

Background This study aimed to describe the mid-term outcomes of different treatments in patients with atrial fibrillation caused tricuspid regurgitation. Methods A retrospective study of patients diagnosed as atrial fibrillation caused moderate-severe tricuspid regurgitation undergoing ablation (n = 411) were reviewed. The surgical cohort (n = 114) underwent surgical ablation and tricuspid valve repair; the catheter cohort (n = 279) was selected from those patients who had catheter ablation. Results The estimated actuarial 5-year survival rates were 96.8% (95% CI: 92.95–97.78) and 92.0% (95% CI: 85.26–95.78) in the catheter and surgical cohort, respectively. Tethering height was showed as independent risk factors for recurrent atrial fibrillation and tricuspid regurgitation in both cohorts. A matched group analysis using propensity-matched was conducted after categorizing total patients by tethering height < 6 mm and ≥ 6 mm. Kaplan–Meier analysis showed in patients with tethering height < 6 mm, there were no differences in survival from mortality, stroke, recurrent atrial fibrillation and tricuspid regurgitation between two groups. In patients with tethering height ≥ 6 mm, there were significantly higher cumulative incidence of stroke (95% CI, 0.047–0.849; P = 0.029), recurrent atrial fibrillation (95% CI, 0.357–09738; P = 0.039) and tricuspid regurgitation (95% CI, 0.359–0.981; P = 0.042) in catheter group. Conclusions Atrial fibrillation caused tricuspid regurgitation resulted in less leaflets coaptation, which risk the recurrence of atrial fibrillation and tricuspid regurgitation. Patients whose tethering height was less than 6 mm showed satisfying improvement in tricuspid regurgitation with the restoration of sinus rhythm after catheter ablation. However, in patients with severe leaflets tethering, the results favored surgical over catheter.

BackgroundStump problems (SPs) secondary to traumatic lower limb amputation had a crucial influence on amputees’ ability to return to living and work. The purpose of this study was to investigate the surgical management strategies of the SPs after above-ankle amputation of the lower limb secondary to trauma.MethodA cohort of clinical cases, who were troubled by SPs after above-ankle amputation following trauma, had undergone revision surgery of the stump and was analyzed retrospectively. Various factors were noted like sex, unilateral or bilateral, amputation type, and causes of trauma. Different SPs like excess soft tissue (where a considerable amount of soft tissue interposed between the rigid elements which hindered the fitting of a prosthesis), scar, ulcers, neuromas, and bone spurs were taken as dependent variables. The relationship between factors and SPs was analyzed.ResultsA total of 80 stumps were treated surgically. The frequency of excess soft tissue in above-knee amputation cases was higher than that in below-knee amputation (p = 0.007). Bone spur occurred more frequently in the unilateral amputation than in bilateral ones (p = 0.018). There was a significant difference in the ADL scores between admission and discharge (p = 0.000).ConclusionStump problems secondary to traumatic lower limb amputation had crucial influence on amputees’ ability to return to living and work, appropriate evaluation and timely surgical revision showed excellent results.
