Background: There are limited data about predictors of atrial fibrillation (AF) recurrence after totally thoracoscopic ablation (TTA). This study investigated the clinical implication of left atrial appendage emptying velocity (LAAV) in patients undergoing TTA.Methods and Results: Patients who underwent TTA between 2012 and 2015 at a tertiary hospital were prospectively enrolled in this study. LAAV was measured and averaged over five heart beats from preoperative transesophageal echocardiography. The primary outcome was a freedom from recurrent AF or atrial flutter (AFL) detected on 24-h Holter monitoring or an electrocardiogram over a 3-year period after TTA. In all, 129 patients were eligible for analysis in this study. The mean (±SD) patient age was 54.4±8.8 years, and 95.3% were male. During the 3 years after TTA, the overall event-free survival rate was 65.3%. LAAV was an independent predictor of recurrent AF/AFL during the 3-year period after TTA (per 1-cm/s increase, adjusted hazard ratio [aHR] 0.95; 95% confidence interval [CI] 0.91–0.99; P=0.016). Event-free survival was significantly lower among patients with a low LAAV (<20 cm/s; n=21) compared with those with a normal (≥40 cm/s; n=38; aHR 6.11; 95% CI 1.42–26.15; P=0.015) or intermediate (LAAV ≥20 and <40 cm/s; n=70; aHR 2.74, 95% CI 1.29–5.83; P=0.009) LAAV.Conclusions: In patients with AF, LAAV was significantly associated with the risk of long-term recurrence of AF after TTA.

[Purpose] The aim of this study was to evaluate the changes in posture and respiratory functions depending on the duration of smartphone usage. [Subjects and Methods] Participants were randomly allocated to 2 groups: group 1 (subjects who used smartphones for <4 hours/day, n=25) and group 2 (subjects who used smartphones for >4 hours/day, n=25). The craniovertebral angles of all participants were measured and scapular indices were calculated to assess the change in posture and forced vital capacity, forced expiratory volume in 1 second, the ratio of forced expiratory volume in 1 second to forced vital capacity, and peak expiratory flow were measured to assess changes in respiratory function. [Results] There were significant differences in the craniovertebral angle, scapular index, and peak expiratory flow depending on the duration of smartphone usage. [Conclusion] The result of this study showed that prolonged use of smartphones could negatively affect both, posture and respiratory function.

[Purpose] The purpose of this study was to determine the effects of aquatic exercise on pulmonary function of patients with spinal cord injury. [Subjects] The subjects were randomly allocated to an aqua group (n=10) and a land group (n=10). [Methods] Both groups trained for 60 minutes, 3 times a week for 8 weeks. Pulmonary function was assessed by measuring the forced vital capacity (FVC), forced expiratory flow rate (FER), force expiratory volume at one second (FEV1) and force expiratory volume at one second/forced vital capacity (FEV1/FVC). [Results] Following the intervention, the aqua group showed significant changes in FVC, FER, FEV1, and FEV1/FVC. The land group showed only significant differences FER. [Conclusion] The results of this study suggest the effects on the aqua group were significantly higher than those on the land group in patients with spinal cord injury.

[Purpose] To investigate whether pain, balance, and stabilization of the lumbar region can be improved through thoracic mobilization in addition to lumbar stabilizaing exercises. [Subjects and Methods] This study recruited 36 subjects with chronic low back pain lasting more than 12 weeks. The subjects recruited for this study participated voluntarily, and provided their signed consent to participation. [Results] Improvement in balance was largest in the lumbar stabilization exercise group, followed by the thoracic mobilization and exercise group, and the traditional physical therapy group, in decreasing order of effect. [Conclusion] In conclusion, lumbar stabilization exercises combined with thoracic mobilization had greater effects on stabilization of the lumbar region pain relief, and improvement of the function of the patients with chronic low back pain.

Upon single treatment against Staphylococus aureus, quercetin–pivaloxymethyl conjugate (Q-POM) had antibacterial activities with minimum inhibitory concentrations (MICs) of 16–32 mg/L. Q-POM showed MIC of 32 mg/L against vancomycin-resistant Enterococcus faceium (VRE), which is remarkably lower than other antibiotics investigated (≥256 mg/L). Under sub-MIC concentrations, Q-POM potentiated the activity of ampicillin, cefepime, and vancomycin against S. aureus and Enterococcus (including highly resistant strains such as hetero-resistant vancomycin-intermediate S. aureus (hVISA), vancomycin-intermediate S. aureus (VISA), and VRE), by decreasing the MICs of these antibiotics by 4–128 folds. Q-POM was found to be partially synergistic with ampicillin and cefepime against S. aureus and Enterococcus, while it was strongly synergistic with vancomycin. Q-POM at 5 mg/L inhibited the formation of biofilms of S. aureus by 24–83% and VRE by 70%. Additionally, Q-POM inhibited the hemolytic activity of S. aureus in a dose-dependent manner. Cytotoxic activity was evaluated in human liver epithelial cells (HepG2), and the 50% cytotoxicity concentration (CC50) value of Q-POM was higher than 50 mg/L. These results indicate the potential use of Q-POM in treatment of methicillin-resistant Staphylococcus aureus (MRSA) and VRE infections.

[Purpose] This study examined the effects of visual feedback balance training on the balance and ankle instability in adult men with functional ankle instability. [Subjects and Methods] Twenty eight adults with functional ankle instability, divided randomly into an experimental group, which performed visual feedback balance training for 20 minutes and ankle joint exercises for 10 minutes, and a control group, which performed ankle joint exercise for 30 minutes. Exercises were completed three times a week for 8 weeks. Bio rescue was used for balance ability. It measured limit of stability at one minute. For ankle instability was measured using Cumberland ankle instability tool (CAIT). This measure was performed before and after the experiments in each group. [Results] The experimental group had significant increase in the Limit of Stability and CAIT score. The control group had significant increase in CAIT score. While the Limit of Stability increased without significance. [Conclusion] In conclusion, visual feedback balance training can be recommended as a treatment method for patients with functional ankle instability.

[Purpose] This study evaluated the effects of water and land-based obstacle training on static balance of chronic stroke patients. [Subjects] The subjects were randomly allocated to an aqua group (n=15) and a land group (n=15). [Methods] Both groups trained for 40 minutes, 3 times a week for 12 weeks. Static balance was assessed by measuring the mean velocities of mediolateral (ML) and anteroposterior (AP), and sway area with the eyes closed. [Results] Following the intervention, both groups showed significant changes in ML velocity, AP velocity, and sway area. The static balance of the aqua group was significantly better than the land group. [Conclusion] The results of this study suggest the feasibility and suitability of obstacle training in water for stroke patients.

Background: The degree of electroanatomical remodeling of the left atrial (LA) affects the clinical outcome after rhythm control of atrial fibrillation (AF). Our hypothesis was that plasma concentrations of transforming growth factor (TGF)-β and tissue inhibitor of metalloproteinase (TIMP)-1 reflect LA voltage and structural remodeling in patients with non-valvular AF. Methods and Results: In the study, 242 patients (male 79.4%, 55.1±11.0 years old) with AF (155 paroxysmal AF, 87 persistent AF) underwent catheter ablation. Pre-ablation plasma concentrations of TGF-β and TIMP-1 and the degree of electroanatomical remodeling quantified by LA voltage map (NavX) and 3D-CT were evaluated. The mean LA voltage and volume were compared in patients with high TGF-β (≥10.0ng/ml, H-TGF) vs. low TGF-β (<10.0ng/ml, L-TGF) and high TIMP-1 (≥1.1ng/ml, H-TIMP) vs. low TIMP-1 (<1.1ng/ml, L-TIMP). Patients with H-TGF had lower mean LA voltage (P=0.014) and greater LA volume (P=0.022), particularly, posterior venous LA volume (P=0.005) than those with L-TGF. In patients with H-TIMP, the mean LA voltage (P=0.019) was lower than those with L-TIMP. LA volume was significantly higher (P<0.001) in patients with ejection fraction ≤58% than those with >58%. Conclusions: In patients with non-valvular AF, high plasma concentrations TGF-β and TIMP-1 and low ejection fraction were closely related with electroanatomical remodeling of LA.

[Purpose] The purpose of this study was to investigate the effect of progressive resistance training (PRT) integrated with foot and ankle compression on the gait ability of post-stroke patients. [Subjects and Methods] Participants were randomly allocated to two groups: the PRT group (n=14) and the control group (n=14). Subjects in the PRT group received training for 30 minutes, five days per week, for a period of six weeks. Gait ability was evaluated using the RsScan system. [Results] Use of PRT integrated with foot and ankle compression resulted in significant improvements in temporal parameters (gait velocity, step time, and double limb support) and spatial parameters (step length, stride length, and heel-to-heel base of support). [Conclusion] Progressive resistance training integrated with foot and ankle compression improved the gait ability of stroke patients. These results suggest the feasibility and suitability of integration of PRT with foot and ankle compression for individuals with stroke.
