Microgravity and Cardiovascular Health in Astronauts: A Narrative Review.

Background: Space exploration has become a major interest for scientific and medical research. With increasing duration and frequency of manned space missions, it is crucial to understand the impact of microgravity on the cardiovascular health of astronauts. We focus on this relationship by reviewing literature that explores how microgravity affects several hemodynamic parameters and cardiovascular biomarkers.

A case series of new-onset headache and neurological issues after thoracolumbar spinal cord stimulators.

Although spinal cord stimulator (SCS) therapy is generally used safely to treat chronic neuropathic pain conditions, this document highlights the less reported complication of unusual neurological problems including headaches. These developed temporally after the initiation of SCS therapy despite initial positive response to pain. The mechanisms might include activation of trigeminal receptors and neuroplasticity after SCS.

Activating waitlists: Identifying barriers and facilitators to pain self-management while waiting.

Objectives: Waitlists for pain management services are often extensive, risking psychological and physical decline and patient non-engagement in treatment once accessed. Currently, for outpatient pain management, no standardised waiting list interventions exist, resulting in passive waiting. To arrest prospective wait-related decline(s), this study aimed to identify the barriers and facilitators to pain self-management while waiting, forming the foundation for a waitlist intervention development.

Registries in allergy: Structure, target groups, and key findings of allergy-focused registries in Germany.

In allergology, clinical registries fill knowledge gaps of epidemiology, mechanisms of allergic diseases, and real-world treatment outcomes. Considering the continuous rise of allergic diseases worldwide, registries become increasingly important for the optimization and harmonization of patient care. In the current review, we present four ongoing allergy-focused registries initiated in Germany.

Experientially-grounded and distributional semantic vectors uncover dissociable representations of conceptual categories.

Neuronal populations code similar concepts by similar activity patterns across the human brain's semantic networks. However, it is unclear to what extent such meaning-to-symbol mapping reflects distributional statistics, or experiential information grounded in sensorimotor and emotional knowledge. We asked whether integrating distributional and experiential data better distinguished conceptual categories than each method taken separately.

Appetite-related Gut Hormone Responses to Feeding Across the Life Course.

Appetite-related hormones are secreted from the gut, signaling the presence of nutrients. Such signaling allows for cross-talk between the gut and the appetite-control regions of the brain, influencing appetite and food intake. As nutritional requirements change throughout the life course, it is perhaps unsurprising that appetite and eating behavior are not constant.

The prevalence and outcomes of pre-admission vitamin D levels in the management of proximal femur fractures.

Objectives: The prevalence of low Vitamin D levels (<30 nmol/L) is about 15.7% globally. The aim of this study was to examine the prevalence of vitamin D deficiency in elderly patients with fragility fractures of the hip by estimating 25-hydroxyvitamin D levels and to assess whether low vitamin D levels at the time of admission affect functional outcomes at 3 months and mortality at 28 days and 1 year.

Environmental enrichment is associated with favorable memory-related functional brain activity patterns in older adults.

Background: In humans, environmental enrichment (EE), as measured by the engagement in a variety of leisure activities, has been associated with larger hippocampal structure and better memory function. The present cross-sectional study assessed whether EE during early life (13-30 years) and midlife (30-65 years) is associated with better preserved memory-related brain activity patterns in older age.

Methods: In total, 372 cognitively unimpaired older adults (aged ≥60 years old) of the DZNE-Longitudinal Study on Cognitive Impairment and Dementia (DELCODE; DRKS00007966) were investigated.

Intermittent cell division dynamics in regenerating Arabidopsis roots reveals complex long-range interactions.

In this work, we present a quantitative comparison of the cell division dynamics between populations of intact and regenerating root tips in the plant model system To achieve the required temporal resolution and to sustain it for the duration of the regeneration process, we adopted a live imaging system based on light-sheet fluorescence microscopy, previously developed in the laboratory. We offer a straightforward quantitative analysis of the temporal and spatial patterns of cell division events showing a statistically significant difference in the frequency of mitotic events and spatial separation of mitotic event clusters between intact and regenerating roots.

No prediction without prevention: A global qualitative study of attitudes toward using a prediction tool for risk of developing depression during adolescence.

Given the rate of advancement in predictive psychiatry, there is a threat that it outpaces public and professional willingness for use in clinical care and public health. Prediction tools in psychiatry estimate the risk of future development of mental health conditions. Prediction tools used with young populations have the potential to reduce the worldwide burden of depression.

Co-design of "Baatcheet," a peer-supported, web-based storytelling intervention for young people with common mental health problems in India.

Background: Engaging with personal mental health stories has the potential to help people with mental health difficulties by normalizing distressing experiences, imparting coping strategies and building hope. However, evidence-based mental health storytelling platforms are scarce, especially for young people in low-resource settings.

Objective: This paper presents an account of the co-design of 'Baatcheet' ('conversation' in Hindi), a peer-supported, web-based storytelling intervention aimed at 16-24-year-olds with depression and anxiety in New Delhi, India.

The quest for early detection of retinal disease: 3D CycleGAN-based translation of optical coherence tomography into confocal microscopy.

Optical coherence tomography (OCT) and confocal microscopy are pivotal in retinal imaging, offering distinct advantages and limitations. OCT offers rapid, noninvasive imaging but can suffer from clarity issues and motion artifacts, while confocal microscopy, providing high-resolution, cellular-detailed color images, is invasive and raises ethical concerns. To bridge the benefits of both modalities, we propose a novel framework based on unsupervised 3D CycleGAN for translating unpaired OCT to confocal microscopy images.
