Recent results of research on the development of biological systems and the related technologies for life support ecosystem in space have been reviewed. The integration of higher plants and algal subsystems and the technologies for food and atmospheric regeneration, water reclamation as waste recycling are the aspects which have been dealt with and need critical evaluation before they can be tested in space. The adaptation of living organisms and their ability to multiply and regenerate in space environment during long duration missions is one of the important criteria for their final selection. It is not yet clear to what extent bioregenerative subsystems can be accommodated in the space station Freedom, which will depend on their mass and functional stability, maintainability and operational cost. But it can be expected that bioregenerative life support systems will continue to evolve during the life time of space station Freedom leading towards an integrated ecosystem with further simplification and an increased degree of closure. Several biological and physico-chemical life support systems currently developed are under investigation on the MIR space station.

Effectiveness of regorafenib in second-line therapy for advanced hepatocellular carcinoma: A systematic review and meta-analysis.
Medicine (Baltimore)
January 2025
Department of Hepatobiliary Surgery, The Third Central Hospital of Tianjin, Tianjin, China.
Background: In patients with advanced hepatocellular carcinoma (HCC) following sorafenib failure, regorafenib has been used as an initial second-line drug. It is unclear the real efficacy and safety of sorafenib-regorafenib sequential therapy compared to placebo or other treatment (cabozantinib or nivolumab or placebo) in advanced HCC.
Methods: Four electronic databases (PubMed, Embase, Web of Science, and Ovid) were systematically searched for eligible articles from their inception to July, 2024.
Factors associated with higher caregiver burden among informal caregivers of Parkinson's disease: A systematic review.
Medicine (Baltimore)
January 2025
Department of Cardiovascular Medicine, the Affiliated Traditional Chinese Medicine Hospital, Southwest Medical University, Luzhou, China.
Background: Parkinson's disease is a progressive neurodegenerative disease and the care burden in informal caregivers is huge. Summarizing factors associated with the informal caregivers burden can improve our understanding of providing proactive support to informal caregivers caring for patients with Parkinson's disease (PwP) at risk, and provides evidence for clinical practice.
Methods: PRISMA guidelines were followed in this systematic review.
Impact of disease duration and surgical intervention on arousal networks in temporal lobe epilepsy.
J Neurosurg
January 2025
Departments of1Biomedical Engineering.
Objective: Epilepsy is a common neurological disease affecting nearly 1% of the global population, and temporal lobe epilepsy (TLE) is the most common type. Patients experience recurrent seizures and chronic cognitive deficits that can impact their quality of life, ability to work, and independence. These cognitive deficits often extend beyond the temporal lobe and are not well understood.

JCO Oncol Pract
January 2025
Section of Hematology & Oncology, Department of Medicine, University of Oklahoma Health Sciences Center, Stephenson Cancer Center, Oklahoma City, OK.
Purpose: Older adults with cancer have unique needs, which likely influence surgical outcomes in the geriatric oncology population. We conducted a systematic review to describe the literature focused on perioperative supportive care interventions for older adults with cancer undergoing surgery.
Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we performed a comprehensive search using the Ovid MEDLINE, CINAHL, and Embase databases for literature published from January 2010 to October 2023.
Oncology Provider and Patient Perspectives on a Cardiovascular Health Assessment Tool utilized during Post-treatment Survivorship Care in Community Oncology (Results from WF-1804CD): Mixed Methods Observational Study.
J Med Internet Res
January 2025
Department of Social Sciences and Health Policy, Wake Forest University School of Medicine, Medical Center Boulevard, Winston-Salem, US.
Background: Most cancer survivors have multiple cardiovascular risk factors, increasing their risk of poor cardiovascular and cancer outcomes. The Automated Heart-Health Assessment (AH-HA) tool is a novel electronic health record clinical decision support tool based on the American Heart Association's Life's Simple 7 cardiovascular health (CVH) metrics to promote CVH assessment and discussion in outpatient oncology. Before proceeding to future implementation trials, it is critical to establish the acceptability of the tool among providers and survivors.
