Common hospital and surgical center responses to the Covid-19 pandemic included curtailing “elective” procedures, which are typically determined based on implications for physical health and survival. However, in the focus solely on physical health and survival, procedures whose main benefits advance components of well-being beyond health, including self-determination, personal security, economic stability, equal respect, and creation of meaningful social relationships, have been disproportionately deprioritized. We describe how female reproduction-related procedures, including abortion, surgical sterilization, reversible contraception devices and in vitro fertilization, have been broadly categorized as “elective,” a designation that fails to capture the value of these procedures or their impact on women's overall well-being. We argue that corresponding restrictions and delays of these procedures are problematically reflective of underlying structural views that marginalize women's rights and interests and therefore threaten to propagate gender injustice during the pandemic and beyond. Finally, we propose a framework for triaging reproduction-related procedures during Covid-19 that is more individualized, accounts for their significance for comprehensive well-being, and can be used to inform resumption of operations as well as subsequent restriction phases.  相似文献

Heat shock protein 72 (HSP72) is expressed in response to stress and has been demonstrated to follow a diurnal expression pattern within monocytes and is sensitive to changes in core temperature. Numerous studies have shown changes in HSP72 expression within cell lines exposed to hyperbaric conditions. No studies have investigated changes in HSP72 expression in vivo. Six males participated in the study and were exposed to hyperbaric air and hyperbaric oxygen a week apart. Monocyte HSP72 was analyzed by flow cytometry at 09:00, 13:00, 17:00, 21:00 with hyperbaric oxygen or hyperbaric air breathing commencing at 15:00 for 78 min at a pressure of 2.8 ATA. HSP72 under normoxia followed the established trend; however, following the hyperbaric air or oxygen exposure a reduction in detectable HSP72 was observed at 17:00 and 21:00. No changes in core temperature were observed between 13:00 and 21:00 for any condition. The data show that HSP72 expression is impaired following hyperbaric air (HA) exposure, when compared with control or hyperbaric oxygen (HO) exposure.  相似文献

Many older adults experience age-related changes that can have negative consequences for food intake. Some older adults continue to eat well despite these challenges showing dietary resilience. We aimed to describe the strategies used by older adults to overcome dietary obstacles and to explore the key themes of dietary resilience. The sample was drawn from the five-year Québec Longitudinal Study "NuAge". It included 30 participants (80% female) aged 73-87 years; 10 with decreased diet quality and 20 with steady or increased diet quality; all had faced key barriers to eating well. Semi-structured interviews explored how age-related changes affected participants' experiences with eating. Thematic analysis revealed strategies used to overcome eating, shopping, and meal preparation difficulties. Key themes of dietary resilience were: prioritizing eating well, doing whatever it takes to keep eating well, being able to do it yourself, getting help when you need it. Implications for health professionals are discussed.  相似文献

A method is presented for empirical subclassification of autistic and autisticlike children, based on observations of current behavior. The advantage of the method is that it identifies profiles of cooccurring behaviors and accordingly assigns children to subtypes. The subtypes are more clinically homogeneous than the overall sample of autistic children. Preliminary findings are presented, including an effort to validate the subclasses by suggesting possible relationships between subtype membership and perinatal markers, developmental milestones, and independent measures of concurrent behavior.This work was supported by postdoctoral training grants MH-15147 and MH-16744 from the National Institute of Mental Health (Siegel), by the Scottish Rite Foundation (Anders, Siegel), by the John Merck Fund (Ciaranello), and by the National Institute of Mental Health grant MH-38064 (Anders, Ciaranello). A portion of this work was presented at the Annual Meeting of the National Society for Children and Adults with Autism, Salt Lake City, July 1983.  相似文献
