Objectives: To determine the amount of change over time on the five dimensions of the 40-item Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-40) that are subjectively meaningful to patients. Minimally important differences (MID), effect sizes (ES) and standardized response means (SRM) are calculated for respondents who indicate only a little change over the time of the study whilst mean change scores, ES and SRM statistics are calculated for those who indicated much change.
Design: Postal survey. Copies of the ALSAQ-40 were completed on two occasions three months apart. Respondents were also asked to indicate how much change they had experienced since baseline on each of the five domains of the questionnaire.
Setting: All patient members of the Motor Neurone Disease Association for England, Wales and Northern Ireland.
Subjects: Seven hundred and sixty-four patient members returned questionnaires at baseline and follow-up.
Results: For those reporting minor change since baseline results varied across dimensions. For example a MID was reflected in a change of 6.67 (SD 16.52) points for the Communication dimension, whilst for the Emotional functioning dimension the change was 2.67 (SD 15.45) points. Similarly ESs and SRMs varied considerably across dimensions. Mean change over time, ES and SRM statistics for those who reported that their health was much worse at follow-up were substantially larger: for example, mean changes ranged from 6.87 (SD 15.87) to 13.79 (SD 22.60).
Conclusions: Results indicate the minimum magnitude of change that is subjectively meaningful to patients. Results indicate that smaller changes than have been suggested previously as significant have a subjectively meaningful adverse effect upon patients.

Aim: We investigated the short- term results of dynamic/semi-rigid stabilization in patients with cervi-cal spinal stenosis and compare them with patients for which decompression and posterior cer-vical fusion was performed.
Material And Methods: 28 patients were included in this study. Group 1 was the semi-rigid group (four male, ten fe-male), group 2 was the fusion group (nine male, five female).
Characterization of the Micro-Morphology and Compositional Distribution of Chang'e-5 Lunar Soil Mineral Surfaces Using TOF-SIMS.

The lunar soil samples returned by China's Chang'e-5 (CE-5) contain valuable information on geological evolutions on the Moon. Herein, by employing high-resolution time-of-flight secondary ion mass spectrometry (TOF-SIMS), five rock chip samples from the CE-5 lunar soil are characterized in-depth, which reveal micro-morphological and compositional features. From the elemental/molecular ion distribution images, minerals such as pyroxene, ilmenite, feldspar, K-rich glass, silica, and silicate minerals are identified, along with their occurrence states and distribution results.

Albuvirtide (ABT) is a novel long-acting fusion inhibitor for human immunodeficiency virus type 1 (HIV-1), and may be co-administered with rifampicin (RIF) in patients concurrent with tubercle bacillus and HIV-1. This study was conducted to investigate the pharmacokinetic effect of co-administration of the two drugs. In the study, 24 healthy volunteers were randomized to receive ABT alone or with RIF.

Phoronida is a small group of marine animals, most of which are characterized by a long larval period and complex metamorphosis. As a result of metamorphosis, their body changes so much that their true anterior and posterior ends are very close to each other, and the intestine becomes long and U-shaped. Using histology and electron microscopy, we have shown that the elongation and change in shape of the digestive tract that occurs during metamorphosis in Phoronopsis harmeri larvae is accompanied by the formation of new parts and changes in ultrastructure.

Aims: Evaluate glycated haemoglobin (HbA1c) and weight changes after 6 months of once-weekly (QW) injectable glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy in UK primary care.
Materials And Methods: Retrospective, non-interventional study, using the Clinical Practice Research Datalink Aurum primary care database, identified adults with type 2 diabetes (T2D) newly initiating a QW injectable GLP-1 RA between January 2020 and November 2021. Dual primary outcomes were proportion of patients with (1) HbA1c < 7% (<53 mmol/mol) and (2) weight loss categories (from 0% to 15+%) after 6 months of continuous GLP-1 RA therapy.
