Myths and Methodologies: Understanding the health impact of head down bedrest for the benefit of older adults and astronauts. Study protocol of the Canadian Bedrest Study.

Weightlessness during spaceflight can harm various bodily systems, including bone density, muscle mass, strength and cognitive functions. Exercise appears to somewhat counteract these effects. A terrestrial model for this is head-down bedrest (HDBR), simulating gravity loss. This mirrors challenges faced by older adults in extended bedrest and space environments. The first Canadian study, backed by the Canadian Space Agency, Canadian Institutes of Health Research, and Canadian Frailty Network, aims to explore these issues. The study seeks to: (1) scrutinize the impact of 14-day HDBR on physiological, psychological and neurocognitive systems, and (2) assess the benefits of exercise during HDBR. Eight teams developed distinct protocols, harmonized in three videoconferences, at the McGill University Health Center. Over 26 days, 23 participants aged 55-65 underwent baseline measurements, 14 days of -6° HDBR, and 7 days of recovery. Half did prescribed exercise thrice daily combining resistance and endurance exercise for a total duration of 1 h. Assessments included demographics, cardiorespiratory fitness, bone health, body composition, quality of life, mental health, cognition, muscle health and biomarkers. This study has yielded some published outcomes, with more forthcoming. Findings will enrich our comprehension of HDBR effects, guiding future strategies for astronaut well-being and aiding bedrest-bound older adults. By outlining evidence-based interventions, this research supports both space travellers and those enduring prolonged bedrest.

Parents' perspective on recovery at home following adenotonsillectomy: a prospective single-centre qualitative analysis.

PURPOSE: In North America, pediatric adenotonsillectomy (TA) is conducted as an ambulatory procedure, thus shifting the burden of postoperative care to parents. The purpose of this study was to describe this parental experience. METHODS: We conducted a prospective single-centre qualitative study, recruiting the families of children (n = 317) undergoing elective TA in 2018. Parents were invited to submit written comments to two open-ended questions. We coded the comments from 144 parents in a grounded theory analysis and report representative exemplars. Themes and subthemes for the problems encountered, and strategies employed by parents, were developed. We then coded and classified factors that helped/hindered parents and developed models of the experience. RESULTS: Some parents felt ill-prepared for the severity and duration of pain. Specific findings included a lack of strategies to manage pain at night, refusals, and night terrors. Parents identified the use of pain scales, pain diaries, and liaison with the research team as helpful supports at home. Inconsistent messaging was a barrier. The odynophagia associated with elixirs of acetaminophen and ibuprofen was a barrier to achieving analgesia. CONCLUSIONS: The findings from this qualitative analysis provide insight into the challenges faced by parents when caring for their children at home following TA; these challenges included difficulties managing physical needs and pain. The analysis suggests that educational content should be standardized and include the use of pain scales and diaries, and both pharmacologic and nonpharmacologic strategies. Development of support at home, including a practicable liaison with health care providers, seems to be warranted. STUDY REGISTRATION: ClinicalTrials.gov (NCT03378830); registered 20 December 2017.

RéSUMé: OBJECTIF: En Amérique du Nord, l'adéno-amygdalectomie pédiatrique est réalisée en intervention ambulatoire, transférant ainsi le fardeau des soins postopératoires aux parents. Le but de cette étude était de décrire cette expérience parentale. MéTHODE: Nous avons réalisé une étude qualitative prospective monocentrique, recrutant les familles d'enfants (n = 317) subissant une adéno-amygdalectomie non urgente en 2018. Les parents ont été invités à soumettre des commentaires écrits sur deux questions ouvertes. Nous avons codé les commentaires de 144 parents dans une analyse théorique ancrée et rapporté des exemples représentatifs. Des thèmes et sous-thèmes pour les problèmes rencontrés, ainsi que des stratégies employées par les parents, ont été développés. Nous avons ensuite codé et classé les facteurs qui aidaient / gênaient les parents et développé des modèles de l'expérience. RéSULTATS: Certains parents se sentaient mal préparés à la gravité et à la durée de la douleur. Les résultats spécifiques comprenaient un manque de stratégies pour gérer la douleur la nuit, les refus et les terreurs nocturnes. Les parents ont indiqué que l'utilisation d'échelles de douleur, de journaux de douleur et de liaison avec l'équipe de recherche étaient des soutiens utiles à la maison. Le manque d'uniformité des messages a constitué un obstacle. L'odynophagie associée aux élixirs d'acétaminophène et d'ibuprofène était un obstacle à l'analgésie. CONCLUSION: Les résultats de cette analyse qualitative donnent un aperçu des défis auxquels font face les parents lorsqu'ils et elles s'occupent de leurs enfants à la maison après une adéno-amygdalectomie; ces défis comprenaient des difficultés à gérer les besoins physiques et la douleur. L'analyse suggère que le contenu éducatif devrait être normalisé et inclure l'utilisation d'échelles et de journaux de douleur, ainsi que de stratégies pharmacologiques et non pharmacologiques. L'élaboration d'un soutien à domicile, y compris d'une communication fonctionnelle avec les prestataires de soins de santé, semble justifiée.

Parental Engagement of a Prototype Electronic Diary in an Ambulatory Setting Following Adenotonsillectomy in Children: A Prospective Cohort Study.

Adenotonsillectomy is performed in children on an outpatient basis, and pain is managed by parents. A pain diary would facilitate pain management in the ambulatory setting. Our objective was to evaluate the parental response rate and the compliance of a prototype electronic pain diary (e-diary) with cloud storage in children aged 2-12 years recovering from adenotonsillectomy and to compare the e-diary with a paper diary (p-diary). Parents recorded pain scores twice daily in a pain diary for 2 weeks post-operation. Parents were given the choice of an e-diary or p-diary with picture message. A total of 208 patients were recruited, of which 35 parents (16.8%) chose the e-diary. Most parents (98%) chose to be contacted by text message. Eighty-one families (47%) returned p-diaries to us by mail. However, the response rate increased to 77% and was similar to that of the e-diary (80%) when we included data texted to the research phone from 53 families. The proportion of diaries with Complete (e-diary:0.37 vs. p-diary:0.4) and Incomplete (e-diary:0.43 vs. p-diary:0.38) data entries were similar. E-diaries provide a means to follow patients in real time after discharge. Our findings suggest that a smartphone-based medical health application coupled with a cloud would meet the needs of families and health care providers alike.
