Kurzfassung: Sublattice reversal epitaxy is demonstrated in lattice-matched GaAs/Ge/GaAs (100) and (111) systems using molecular beam epitaxy, and confirmed by reflection high energy electron diffraction and preferential etching. In the GaAs/Ge/GaAs (100) system, the sublattice reversal is assisted by self-annihilation of the antiphase domains generated at the GaAs/Ge interface. In the GaAs/Ge/GaAs (111) system, the sublattice reversal results from the unique structure of the As-terminated Ge (111) surfaces. The quality of the sublattice-reversed GaAs crystal is investigated using cross-sectional transmission electron microscopy. A method to fabricate a periodically domain-inverted structure using sublattice reversal epitaxy is demonstrated for the GaAs/Ge/GaAs (100) system.

Kurzfassung: We aimed to compare longitudinal brain atrophy in patients with neuromyelitis optica spectrum disorder (NMOSD) with healthy controls (HCs). The atrophy rate in patients with anti-aquaporin-4 antibody-positive NMOSD (AQP4 + NMOSD) was compared with age-sex-matched HCs recruited from the Japanese Alzheimer’s Disease Neuroimaging Initiative study and another study performed at Chiba University. Twenty-nine patients with AQP4 + NMOSD and 29 HCs were enrolled in the study. The time between magnetic resonance imaging (MRI) scans was longer in the AQP4 + NMOSD group compared with the HCs (median; 3.2 vs. 2.9 years, P = 0.009). The annualized normalized white matter volume (NWV) atrophy rate was higher in the AQP4 + NMOSD group compared with the HCs (median; 0.37 vs. − 0.14, P = 0.018). The maximum spinal cord lesion length negatively correlated with NWV at baseline MRI in patients with AQP4 + NMOSD (Spearman’s rho = − 0.41, P = 0.027). The annualized NWV atrophy rate negatively correlated with the time between initiation of persistent prednisolone usage and baseline MRI in patients with AQP4 + NMOSD (Spearman’s rho = − 0.43, P = 0.019). Patients with AQP4 + NMOSD had a greater annualized NWV atrophy rate than HCs. Suppressing disease activity may prevent brain atrophy in patients with AQP4 + NMOSD.

Kurzfassung: The purpose of this study was to investigate the effects of surgeon-related factors on the surgical outcome of pars plana vitrectomy (PPV) and scleral buckling (SB) surgery on eyes with a rhegmatogenous retinal detachment (RRD). This was a nationwide, multicenter, observational study of the data in the Japan-RD Registry. Registered cases that had undergone surgery for a RRD by 128 accredited surgeons in 26 institutions were studied. The surgeon-related factors that significantly affected surgical success and visual outcomes of simple RRD treated by PPV or SB at 6 months postoperatively were analyzed and compared. Among 3446 registered cases, 2533 cases met the inclusion criteria with 1896 in the PPV group and 637 cases in the SB group. The median total number of lifetime cases was 150 and the rate of surgeries/year was 22. Multivariate regression analyses showed that the number and rate of surgeries/year were not significantly associated with the surgical outcome in the PPV group. However, surgeons with a higher average annual number of surgeries had significantly better surgical outcomes in the SB group ( P = 0.038). Analyses of a nationwide registry showed that SB but not PPV surgeries require sufficient experience and case numbers to acquire and maintain skills to treat RRDs successfully.
