025). The field of view results were the highest in the hypertonic saline group, and the lowest in the lidocaine group. The pain scores were the lowest in the lidocaine group, whereas they were the highest in the hypertonic saline group. The discomfort scores were the lowest in the xylometazoline group, but the highest in the lidocaine and isotonic saline groups.Conclusion The use of hypertonic saline facilitated the NPL procedure by improving the clinician's field of view. Moreover, intranasal hypertonic saline reduced the patient's discomfort. Intranasal hypertonic saline can be a good alternative to premedication before NPL.Purpose The effectiveness of a 12-month home-exercise program on trunk muscle strength after lumbar spine fusion surgery was evaluated. Materials and methods Three months postoperatively, 98 patients were randomized either to the exercise group (EG), with a progressive 12-month home-based exercise program, or to usual care group (UCG), with one guidance session for light home-exercises. Maximal trunk muscle strength was measured by a strain-gauge dynamometer and trunk extensor endurance was measured by Biering-Sørensen's test at baseline and after the intervention. Results The mean change in extension strength during the intervention was 75 N in EG and 58 N in UCG. Flexion strength improved 50 N in UCG and 45 N in EG. Trunk extension/flexion strength ratio changed from 0.90 to 1.02 in EG and from 0.98 to 1.00 in UCG. In EG, Biering-Sørensen's test improved by 17 s, and in UCG, it improved by 24 s. No statistically significant between-group differences were found in any variables. Median exercise frequency in EG decreased from 2.5×/week during the first two intervention months to 1.7×/week during the last two intervention months. Conclusions Twelve-month progressive exercise program was equally effective as usual care in improving trunk muscle strength. Home exercise adherence decreased, which may have influenced the strength changes.Implications for rehabilitationThe 12-month home-based exercise program was equally as effective as usual care after lumbar spine fusion (LSF) in improving trunk muscle strength, however, the back-specific exercises led to better trunk muscle strength balance in exercise group only.The adherence to the home based exercise program is a challenge; therefore, different techniques could be implemented to provide purposeful support for each individual in their long-term exercising.It is important to recognize those who need more individualized rehabilitation in recovery of the spine function, while others may manage with subtle intervention after LSF.Background The Harmony transcatheter pulmonary valve (TPV) was designed for treatment of postoperative pulmonary valve regurgitation in patients with repaired right ventricular outflow tracts. Methods The Native TPV EFS (Early Feasibility Study) is a prospective, multicenter, nonrandomized feasibility study. Three-year outcomes are reported. Results Of 20 implanted patients, 17 completed 3-year follow-up (maximum 4.1 years). There were no deaths and 2 early explants. One patient did not complete the 3-year visit. In patients with available 3-year echocardiographic data, 1 had a mild paravalvular leak and the rest had none/trace; 1 patient had mild pulmonary valve regurgitation and the remainder had none/trace. The 3-year mean right ventricular outflow tract echocardiographic gradient was 15.7±5.5 mm Hg. Radiographically, no late frame fractures or erosions were identified. At 2 years, 2 patients presented with an increased echocardiographic outflow gradient (1 mixed lesion with moderate/severe pulmonary valve regurgitation). Computed tomography scans identified neointimal tissue ingrowth within the stent frame in both patients, and they were treated successfully with a transcatheter valve-in-valve procedure (Melody TPV). Additional follow-up computed tomography scans performed at 3.2±0.5 years after implant were obtained in 16 patie
