RESUMEN

OBJECTIVE: The objective of this review is to explore critical illness survivors' experiences of attending an intensive care unit (ICU) follow-up service. INTRODUCTION: A significant proportion of critical illness survivors will require ICU follow-up care to support adverse symptoms in health domains, including cognition, mental health, and physical and social function. While there is consensus on the need for ICU follow-up services, systematic reviews to date have not identified any significant impact of ICU follow-up services on clinical health outcomes. An understanding of survivors' experiences of attending an ICU follow-up service may improve the effectiveness and design of such services. INCLUSION CRITERIA: This review will include studies that explore the experiences of adult ( 18 years of age) critical illness survivors who attended an ICU follow-up service following discharge from an ICU, regardless of the admitting diagnosis or ICU length of stay. METHODS: This review will be conducted in line with the JBI methodological framework for qualitative systematic reviews. Electronic databases, including MEDLINE, CINAHL, PsycINFO, Embase, and Web of Science Core Collection, will be searched to identify relevant studies for inclusion in the review. Studies will be screened by 2 independent reviewers. Critical appraisal, data extraction, and data synthesis will be completed by 2 independent reviewers using a meta-aggregation method for data synthesis. Confidence in the research findings will be assessed and assigned a ConQual score. REVIEW REGISTRATION: PROSPERO CRD42023404585.

RESUMEN

Following development, the avian brain continues to produce neurons throughout adulthood, which functionally integrate throughout the telencephalon, including the hippocampus. In food-storing birds like the black-capped chickadee (Poecile atricapillus), new neurons incorporated into the hippocampus are hypothesized to play a role in spatial learning. Previous results on the relation between hippocampal neurogenesis and spatial learning, however, are correlational. In this study, we experimentally suppressed hippocampal neuronal recruitment and tested for subsequent effects on spatial learning in adult chickadees. After chickadees exhibited significant learning, we treated birds with daily injections of either saline or methylazoxymethanol (MAM), a toxin that suppresses cell proliferation in the brain and monitored subsequent spatial learning. MAM treatment significantly reduced cell proliferation around the lateral ventricles and neuronal recruitment in the hippocampus, measured using the cell birth marker bromodeoxyuridine. MAM-treated birds performed significantly worse than controls on the spatial learning task 12 days following the initiation of MAM treatment, a time when new neurons would begin functionally integrating into the hippocampus. This difference in learning, however, was limited to a single trial. MAM treatment did not affect any measure of body condition, suggesting learning impairments were not a product of non-specific adverse effects of MAM. This is the first evidence of a potential causal link between hippocampal neurogenesis and spatial learning in birds.
