Vascularized lymph node transfer (VLNT) is a well-established surgical approach for treating lower extremity lymphedema (LEL). Since VLNT takes time to show effect, a combined approach with lymphaticovenular anastomosis (LVA) may be more advantageous to patients by inducing an immediate improvement. This study aims to describe our experience and evaluate the results of a combined approach. In this retrospective review, we analyzed a total of 12 patients that underwent simultaneous supraclavicular VLNT and LVA for the treatment of secondary LEL with the ISL stage II or III. Patients who had a follow-up period of less than 12 months were excluded. The supraclavicular flap, including superficial lymphoid tissue as well as deep cervical nodes, was harvested and anastomosed to the posterior tibial vessels. The pre- and postoperative change of circumference difference ratios and LEL index were compared. All twelve flaps survived without re-exploration. An average of 2.3 LVAs were simultaneously performed. At 12.9 months of follow-up (range, 12–16 months), the postoperative mean circumference ratio was significantly improved than pre-operative in 10 cm above the knee (7.9 ± 7.2% vs 15.0 ± 7.6%, p = 0.01), 10 cm below the knee (8.5 ± 7.5% vs 17.4 ± 12.7%, p = 0.03) and lateral malleolus (16.5 ± 15.5% vs 28.6 ± 17.9%, p = 0.03). Also, the mean LEL index was decreased (preoperative 324.3 ± 53.0 vs postoperative 298.0 ± 44.6, p = 0.242) and eight patients showed improvement in LEL stage. The combined approach showed a significant decrease in the circumference of LEL. Additional LVAs could reinforce the effect of a VLNT. Larger series with longer follow-up is needed to confirm our findings. [ABSTRACT FROM AUTHOR]

Spin and lattice are two fundamental degrees of freedom in a solid, and their fluctuations about the equilibrium values in a magnetic ordered crystalline lattice form quasiparticles termed magnons (spin waves) and phonons (lattice waves), respectively. In most materials with strong spin-lattice coupling (SLC), the interaction of spin and lattice induces energy gaps in the spin wave dispersion at the nominal intersections of magnon and phonon modes. Here we use neutron scattering to show that in the two-dimensional (2D) van der Waals honeycomb lattice ferromagnetic CrGeTe3, spin waves propagating within the 2D plane exhibit an anomalous dispersion, damping, and breakdown of quasiparticle conservation, while magnons along the c axis behave as expected for a local moment ferromagnet. These results indicate the presence of dynamical SLC arising from the zero-temperature quantum fluctuations in CrGeTe3, suggesting that the observed in-plane spin waves are mixed spin and lattice quasiparticles fundamentally different from pure magnons and phonons. CrGeTe3 is a van der Waals honeycomb ferromagnet, known for exhibiting strong coupling between lattice and spin degrees of freedom. Here, Chen et al perform neutron scattering on CrGeTe3, find a broadened spin-wave excitation resulting from zero-temperature motion of the atoms in the lattice. [ABSTRACT FROM AUTHOR]

Background: The occurrence of thyroid cancer has increased dramatically, and postoperative scars are placed at easily visible locations. Many patients show stronger desire for scar prevention. So far, numerous approaches have been discussed for the treatment of scars; this study is conducted to verify whether the early application of combined therapy contributes to minimal scar formation. Methods: Between March 2019 and December 2019, total of 64 patients with thyroidectomy scars of a size greater than 4.5 cm located on the anterior neck were enrolled in this prospective pilot study. Subjective and objective evaluation were carried out using the Patient and Observer Scar Assessment Scale (POSAS) at one, two, and six months after operation. Results were compared between a treatment group and a non‐treatment group. Results: In PSAS score, the mean values of pain, itching sensation, pliability, thickness, and relief were significantly higher in the laser and steroid treatment group (p = 0.009, p = 0.000, p = 0.013, p = 0.002, and p = 0.007). The value of color of the scars showed no significant differences (p = 0.504). In OSAS score, parameter of thickness, relief, and surface area score was significantly higher score in the combination group (p = 0.029, 0.035, and 0.020), while vascularity, pigmentation, and pliability were not significantly different between two groups (p = 0.548, p = 0.983, and p = 0.128). Conclusion: This study demonstrates that early combination therapy contributes to scar improvement to a meaningful extent based on POSAS. We believe that the combined therapy has a synergy effect on scar management, which improves the patients' quality of life in relation to their postoperative scars. [ABSTRACT FROM AUTHOR]
