Objectives: To estimate thresholds for defining meaningful within-patient improvement from baseline to weeks 13-24 and interpreting meaningfulness of between-group difference for the non-transfusion-dependent beta-thalassaemia patient-reported outcome (NTDT-PRO) tiredness/weakness (T/W) and shortness of breath (SoB) scores. A secondary objective was to determine the symptom severity threshold for the NTDT-PRO T/W domain to identify patients with symptomatic T/W.

Design: Pooled blinded data from the phase 2, double-blind, placebo-controlled, randomised BEYOND trial in NTDT (NCT03342404) were used.

Background: Fatigue is an important symptom for most patients with axial spondyloarthritis (axSpA). The FACIT-Fatigue is a 13-item patient-reported outcome (PRO) instrument that has been used in axSpA clinical trials to measure fatigue severity and impact on daily activities. However, the psychometric properties of the FACIT-Fatigue are not fully evaluated across the entire spectrum of axSpA including non-radiographic axSpA (nr-axSpA) and radiographic axSpA (r-axSpA).

The photocatalytic reduction of CO with HO into valuable chemicals is a sustainable carbon-neutral technology for renewable energy; however, the photocatalytic activity and product selectivity remain challenging. Herein, an S-scheme heterojunction photocatalyst with superior CO photoreduction performance─porous CN (CN) nanosheets anchored with zinc(II) tetra(4-cyanophenyl)porphyrin (ZnTP) nanoassemblies (denoted as ZnTP/CN)─was designed and prepared via a simple self-assembly process. The constructed ZnTP/CN heterojunction had rich accessible active sites, improved CO absorption capacity, and high charge carrier separation efficiency caused by the S-scheme heterojunction.

Photocatalytic conversion of CO into renewable fuels with high efficiency and selectivity is desirable for solar energy utilization, but remains a great challenge. Herein, cobalt(II)-porphyrin functionalized conjugated polymers with acetylene bridging units, assembled through the Sonogashira cross coupling reaction, as heterogeneous catalysts for CO photoreduction were presented. Experimental investigations and density functional theory calculations demonstrated the crucial roles of Co centers in porphyrin units for CO activation and conversion, while excessive acetylene group prompted the competing hydrogen evolution reaction and reduced the selectivity.

Efficient charge separation and sufficiently exposed active sites are both critical limiting factors for solar-driven organic contaminant degradation. Herein, we describe a hierarchical heterojunction photocatalyst fabricated by the growth of ZnInS nanosheets on micro-tubular CN (denoted as ZIS/TCN). This ZIS/TCN heterojunction photocatalyst can take advantage of the hollow structure with stronger light absorption capacity and more active sites, and its heterostructure can accelerate the separation and transfer of photogenerated charge carriers.

Solar-driven reduction of CO into renewable carbon forms is considered as an alternative approach to address global warming and the energy crisis but suffers from low efficiency of the photocatalysts. Herein, a direct Z-Scheme SnS /sulfur-bridged covalent triazine frameworks (S-CTFs) photocatalyst (denoted as SnS /S-CTFs) was developed, which could efficiently adsorb CO owing to the CO -philic feature of S-CTFs and promote separation of photoinduced electron-hole pairs. Under visible-light irradiation, SnS /S-CTFs exhibited excellent performance for CO photoreduction, yielding CO and CH with evolution rates of 123.
