AI Article Synopsis

  • - The study investigates how astronauts' preferences for orientation may change with training that reduces space motion sickness (SMS), which has variable sensory cue priorities among individuals.
  • - Using virtual reality, researchers created immersive environments and compared the effects of training on orientation preferences between a trained group, exposed to rotating visuals, and an untrained control group.
  • - Findings revealed that trained subjects experienced a significant reduction in SMS symptoms and altered their orientation preferences, relying less on visual cues, indicating a need for tailored training methods for astronauts.

Article Abstract

Background: Astronauts' orientation preferences tend to correlate with their susceptibility to space motion sickness (SMS). Orientation preferences appear universally, since variable sensory cue priorities are used between individuals. However, SMS susceptibility changes after proper training, while orientation preferences seem to be intrinsic proclivities. The present study was conducted to investigate whether orientation preferences change if susceptibility is reduced after repeated exposure to a virtual reality (VR) stimulus environment that induces SMS.

Methods: A horizontal supine posture was chosen to create a sensory context similar to weightlessness, and two VR devices were used to produce a highly immersive virtual scene. Subjects were randomly allocated to an experimental group (trained through exposure to a provocative rotating virtual scene) and a control group (untrained). All subjects' orientation preferences were measured twice with the same interval, but the experimental group was trained three times during the interval, while the control group was not.

Results: Trained subjects were less susceptible to SMS, with symptom scores reduced by 40%. Compared with untrained subjects, trained subjects' orientation preferences were significantly different between pre- and posttraining assessments. Trained subjects depended less on visual cues, whereas few subjects demonstrated the opposite tendency.

Conclusion: Results suggest that visual information may be inefficient and unreliable for body orientation and stabilization in a rotating visual scene, while reprioritizing preferences for different sensory cues was dynamic and asymmetric between individuals. The present findings should facilitate customization of efficient and proper training for astronauts with different sensory prioritization preferences and dynamic characteristics.Chen W, Chao J-G, Zhang Y, Wang J-K, Chen X-W, Tan C.

Background: Clean intermittent catheterization (CIC) is the golden standard in patients with lower urinary tract dysfunction, leading to bladder emptying problems, due to neurogenic or non-neurogenic causes. CIC affects patient Quality of Life (QoL) both positively and negatively.

Objectives: The aim of this systematic review is to determine which measurements are used to report on the QoL of patients who are on CIC in the currently available literature, to determine the overall QoL of patients who are on CIC and lastly, to determine whether QoL in patients who are on CIC is dependent on the underlying cause (neurogenic vs non-neurogenic).

Legume consumption and sustainability - The minority goes green.

Appetite

The current food systems and the dominating dietary patterns in most EU countries contribute to climate change and are not sustainable. Legumes have the potential to make consumption patterns more sustainable, especially if they come from local or organic production systems. Yet, legume consumption in Germany is low.

Although glycosidic bonds in purines typically involve the N9 position, the chemical synthesis of adenosine produces N7-ribofuranosyladenine (7A) as a kinetically favorable ribosylation product. Similarly, in the synthesis of LNA-adenosine (AL), a minor product, N7-LNA-adenosine (7AL), is observed. While extensive research has focused on investigating the properties of N9-regioisomers of adenosine, 7A has been largely overlooked and considered as a side-product.

Purpose: The study aimed to explore speech-language pathologists' practices regarding image selection and use in the treatment of people living with aphasia. Images are widely utilised with people living with aphasia, however, supporting their communication optimally remains challenging.

Method: Ninety-two speech-language pathologists from South Africa, Australia, USA, and the UK completed a custom-designed online survey.

Development of a rehabilitation programme for young adult cancer survivors using co-production.

Res Involv Engagem

December 2024

User Perspectives and Community-based Interventions, Department of Public Health, University of Southern Denmark, Odense, Denmark.

Background: Young adult cancer survivors, defined as individuals aged 18-39 who have completed primary curative treatment, face numerous age-specific biopsychosocial late effects that impact health-related quality of life negatively. Rehabilitation can enhance participation in life roles, work, leisure activities and health-related quality of life. However, there is a lack of age-specific cancer rehabilitation for this population, leaving many young adults with diminished self-efficacy in managing their challenges, resulting in unmet needs.
