Genome and clonal hematopoiesis stability contrasts with immune, cfDNA, mitochondrial, and telomere length changes during short duration spaceflight.

Background: The Inspiration4 (I4) mission, the first all-civilian orbital flight mission, investigated the physiological effects of short-duration spaceflight through a multi-omic approach. Despite advances, there remains much to learn about human adaptation to spaceflight's unique challenges, including microgravity, immune system perturbations, and radiation exposure. Methods: To provide a detailed genetics analysis of the mission, we collected dried blood spots pre-, during, and post-flight for DNA extraction. Telomere length was measured by quantitative PCR, while whole genome and cfDNA sequencing provided insight into genomic stability and immune adaptations. A robust bioinformatic pipeline was used for data analysis, including variant calling to assess mutational burden. Result: Telomere elongation occurred during spaceflight and shortened after return to Earth. Cell-free DNA analysis revealed increased immune cell signatures post-flight. No significant clonal hematopoiesis of indeterminate potential (CHIP) or whole-genome instability was observed. The long-term gene expression changes across immune cells suggested cellular adaptations to the space environment persisting months post-flight. Conclusion: Our findings provide valuable insights into the physiological consequences of short-duration spaceflight, with telomere dynamics and immune cell gene expression adapting to spaceflight and persisting after return to Earth. CHIP sequencing data will serve as a reference point for studying the early development of CHIP in astronauts, an understudied phenomenon as previous studies have focused on career astronauts. This study will serve as a reference point for future commercial and non-commercial spaceflight, low Earth orbit (LEO) missions, and deep-space exploration.

Geospatially-resolved public-health surveillance via wastewater sequencing.

Wastewater, which contains everything from pathogens to pollutants, is a geospatially-and temporally-linked microbial fingerprint of a given population. As a result, it can be leveraged for monitoring multiple dimensions of public health across locales and time. Here, we integrate targeted and bulk RNA sequencing (n=1,419 samples) to track the viral, bacterial, and functional content over geospatially distinct areas within Miami Dade County from 2020-2022. First, we used targeted amplicon sequencing (n=966) to track diverse SARS-CoV-2 variants across space and time, and we found a tight correspondence with clinical caseloads from University students (N = 1,503) and Miami-Dade County hospital patients (N = 3,939 patients), as well as an 8-day earlier detection of the Delta variant in wastewater vs. in patients. Additionally, in 453 metatranscriptomic samples, we demonstrate that different wastewater sampling locations have clinically and public-health-relevant microbiota that vary as a function of the size of the human population they represent. Through assembly, alignment-based, and phylogenetic approaches, we also detect multiple clinically important viruses (e.g., norovirus ) and describe geospatial and temporal variation in microbial functional genes that indicate the presence of pollutants. Moreover, we found distinct profiles of antimicrobial resistance (AMR) genes and virulence factors across campus buildings, dorms, and hospitals, with hospital wastewater containing a significant increase in AMR abundance. Overall, this effort lays the groundwork for systematic characterization of wastewater to improve public health decision making and a broad platform to detect emerging pathogens.

Collection of Biospecimens from the Inspiration4 Mission Establishes the Standards for the Space Omics and Medical Atlas (SOMA).

The SpaceX Inspiration4 mission provided a unique opportunity to study the impact of spaceflight on the human body. Biospecimen samples were collected from the crew at different stages of the mission, including before (L-92, L-44, L-3 days), during (FD1, FD2, FD3), and after (R+1, R+45, R+82, R+194 days) spaceflight, creating a longitudinal sample set. The collection process included samples such as venous blood, capillary dried blood spot cards, saliva, urine, stool, body swabs, capsule swabs, SpaceX Dragon capsule HEPA filter, and skin biopsies, which were processed to obtain aliquots of serum, plasma, extracellular vesicles, and peripheral blood mononuclear cells. All samples were then processed in clinical and research laboratories for optimal isolation and testing of DNA, RNA, proteins, metabolites, and other biomolecules. This paper describes the complete set of collected biospecimens, their processing steps, and long-term biobanking methods, which enable future molecular assays and testing. As such, this study details a robust framework for obtaining and preserving high-quality human, microbial, and environmental samples for aerospace medicine in the Space Omics and Medical Atlas (SOMA) initiative, which can also aid future experiments in human spaceflight and space biology.

A Virtual Resiliency Intervention for Parents of Children with Autism: A Randomized Pilot Trial.

Parents of children with Autism experience high levels of stress. Resiliency is the ability to cope and adapt when faced with stressful events. This randomized, waitlist controlled pilot trial examines the feasibility, acceptability, and preliminary efficacy of an adapted virtual mind-body group intervention for parents of children with ASD. The intervention was feasible and acceptable. The immediate treatment group showed no difference in distress and greater improvement in resiliency and stress reactivity/coping relative to the delayed treatment group, (M difference 5.78; p = .038 and M difference 7.78; p = .001 respectively). Findings showed promising feasibility, acceptability, and preliminary efficacy for parents of children with ASD.

A Virtual Resiliency Intervention Promoting Resiliency for Parents of Children with Learning and Attentional Disabilities: A Randomized Pilot Trial.

OBJECTIVES: One in five children have a learning and attentional disability (LAD). Parents of children with LAD are vulnerable to distress, but an evidence-based treatment has not been developed. METHODS: From June 2016 to November 2017, we conducted a mixed methods study to adapt and assess the virtual delivery of a mind-body group resiliency program, the Stress Management and Resiliency Training-Relaxation Response Resiliency Program (SMART-3RP), to meet the needs of parents of children with LAD; this is an 8-session weekly group intervention. In the first phase, we conducted 4 parent focus group interviews, 2 professional focus group interviews, and 5 professional individual interviews, and 1 pilot group to adapt the SMART-3RP to target the needs of parents of children with LAD. In the second phase, we conducted a pilot wait-list controlled study to assess the feasibility, acceptability, and preliminary efficacy of a videoconferencing delivery of the adapted program. Parents were randomized to an immediate intervention group (IG) or wait-list control group (WC). Surveys were administered at baseline (time 1), end of intervention for the IG or 3 months post-baseline for the WC (time 2), and 3 months post treatment for the IG or end of intervention for the WC (time 3). RESULTS: Qualitative findings illustrated high levels of parental stress, with primary stressors including navigating the educational system, interactions with other parents, familial concerns, and financial and professional sacrifices. We adapted the manual to target these stressors and modified session logistics and delivery. Fifty-three parents (mean age = 46.8; 90.6% female) participated nationally in the pilot trial. 62.5% of participants completed ≥ 6/8 sessions; 81.8% reported continued daily/weekly relaxation response exercise practice. T1-T2 comparisons found that IG versus WC participants showed significant improvements in distress [VAS], ∆M = - 1.95; d = .83 and resilience [CES], ∆M = 6.38; d = .83, as well as stress coping [MOCS-A] ∆M = 8.69; d = 1.39; depression and anxiety [PHQ-4], ∆M = - 1.79; d = .71; social support [MOS-SSS], ∆M = 5.47; d = .71; and empathy [IRI], ∆M = 3.17; d = .77; improvements were sustained at the 3 month post intervention follow-up. CONCLUSION: Pilot wait-list randomized trial findings showed promising feasibility, acceptability, and preliminary efficacy for the SMART-3RP intervention adapted for parents of children with LAD. This virtually-delivered resiliency intervention improved parents' distress, resiliency, and stress coping, which were sustained. CLINICAL TRIALS ID: NCT02772432.
