OBJECTIVES Ankylosing spondylitis (AS) is associated with an increased spinal fracture risk due to the loss of elasticity in spinal motion segments. With the introduction of biological disease-modifying antirheumatic drug (bDMARD) treatment for AS, the individual course of the disease has been ameliorated. This study aims to examine the association of bDMARD treatment and risk of spinal fractur...
Prophylaxis against Pneumocystis jirovecii pneumonia (PCP) is recommended for at least 4-12 months after solid organ transplant. In our center, renal transplant recipients receive only 1 month of post-transplant trimethoprim-sulfamethoxazole, which also may provide limited protection against Nocardia. We identified only 4 PCP cases and 4 Nocardia cases in 1352 patients receiving renal and renal...
Allene (H2C═C═CH2; a-C3H4) and propyne (CH3C≡CH; p-C3H4) are important species in various chemical environments. In combustion processes, the reactions of hydroxyl radicals with a-C3H4 and p-C3H4 are critical in the overall fuel oxidation system. In this work, rate coefficients of OH radicals with allene (OH + H2C═C═CH2 → products) and propyne (OH + CH3C≡CH → products) were measured behind refl...
Ni et al . (Research Articles, 20 March 2020, p. 1352) report bulk trap densities of 10 11 cm –3 and an increase in interfacial by one to four orders magnitude from drive-level capacitance profiling lead halide perovskites. From electrostatic arguments, we show that the results are not but a consequence geometrical charge injection into perovskite layer.
