Test-retest reliability of cardiopulmonary exercise test-derived metrics in individuals with COPD versus healthy controls.

Background: Cardiopulmonary exercise testing (CPET) is usually considered the gold standard for assessing maximal oxygen consumption (V̇O), a health and performance marker in patients with chronic obstructive pulmonary disease (COPD). Despite the widespread application of CPET, the absolute and relative test-retest reliability of CPET-derived metrics remains unexamined.

Objective: To examine and compare test-retest reliability of CPET derived metrics in individuals with COPD and healthy matched controls.

Gate- and flux-tunable sin(2φ) Josephson element with planar-Ge junctions.

Hybrid superconductor-semiconductor Josephson field-effect transistors (JoFETs) function as Josephson junctions with gate-tunable critical current. Additionally, they can feature a non-sinusoidal current-phase relation (CPR) containing multiple harmonics of the superconducting phase difference, a so-far underutilized property. Here we exploit this multi-harmonicity to create a Josephson circuit element with an almost perfectly π-periodic CPR, indicative of a largely dominant charge-4e supercurrent transport.

CAR T-cell-associated secondary malignancies challenge current pharmacovigilance concepts.

Suspected adverse reactions following chimeric antigen receptor T-cell (CAR T) treatment include more and more cases of secondary T-cell malignancies. The causality assessment of such suspected reactions challenges established evaluation practices due to (i) patient and product-specific risk factors and (ii) incomplete data available with post-marketing reports submitted to competent authorities. This is of particular relevance for gene therapy products that integrate into the host genome.

Tralokinumab Treatment of Atopic Dermatitis Induces a Progressive Transcriptomic Response.

Atopic dermatitis is characterized by a complex epidermal barrier deficiency and exaggerated immune responses dominated by type 2 mechanisms with variable contributions of additional immune axes. IL-13 is overexpressed in atopic dermatitis skin and a key driver of both barrier dysfunction and inflammation. In this study, we prospectively studied the effects of IL-13 inhibition with tralokinumab on cutaneous transcriptome profiles using RNA sequencing of biopsies from 16 patients with moderate-to-severe atopic dermatitis obtained at baseline, week 2, and week 16.
