We proposed the Relational Activation of Resilience model to explain how leaders could utilize relationships to activate resilience during crisis and illustrated it using an abbreviated case study of Tan Tock Seng Hospital during the severe acute respiratory syndrome crisis in Singapore in 2003. Early signs of the crisis were recognized by organizational leaders, who then ushered liminality—a period when routines were disrupted, and new relational connections were made to allow members to adjust psychologically, emotionally, and socially, to activate resilience. Within the liminal period, leaders influenced the formation of new connections through mutual and swift trust and utilized these networks to enable collective meaning‐making and sensemaking. In addition, leaders communicated mindfully via these networks to promote positive emotional connections among members. These leadership tasks resulted in the formation of relational networks that could serve as social, emotional, and cognitive resources for organizational resilience.

BACKGROUND: Evidence from observational studies suggests that diets high in omega-3 long-chain polyunsaturated fatty acids (PUFA) may protect people from cognitive decline and dementia. The strength of this potential protective effect has recently been tested in randomized controlled trials. OBJECTIVES: To assess the effects of omega-3 PUFA supplementation for the prevention of dementia and cognitive decline in cognitively healthy older people. METHODS: Search: We searched ALOIS-the Cochrane Dementia and Cognitive Improvement Group's Specialized Register on-6 April 2012 using the terms: "omega 3", PUFA, "fatty acids", "fatty acid", fish, linseed, eicosapentaenoic, docosahexaenoic. Selection criteria: Randomised controlled trials of an omega-3 PUFA intervention which was provided for a minimum of six months to participants aged 60 years and over who were free from dementia or cognitive impairment at the beginning of the study. Two review authors independently assessed all trials. Data collection and analysis: The review authors sought and extracted data on incident dementia, cognitive function, safety and adherence, either from published reports or by contacting the investigators for original data. Data were extracted by two review authors. We calculated mean difference (MD) or standardised mean differences (SMD) and 95% confidence intervals (CI) on an intention-to-treat basis, and summarized narratively information on safety and adherence. MAIN RESULTS: Information on cognitive function at the start of a study was available on 4080 participants randomised in three trials. Cognitive function data were available on 3536 participants at final follow-up. In two studies participants received gel capsules containing either omega-3 PUFA (the intervention) or olive or sunflower oil (placebo) for six or 24 months. In one study, participants received margarine spread for 40 months; the margarine for the intervention group contained omega-3 PUFA. Two studies had cognitive health as their primary outcome; one study of cardiovascular disease included cognitive health as an additional outcome. None of the studies examined the effect of omega-3 PUFA on incident dementia. In two studies involving 3221 participants there was no difference between the omega-3 and placebo group in mini-mental state examination score at final follow-up (following 24 or 40 months of intervention); MD-0.07 (95% CI-0.25 to 0.10). In two studies involving 1043 participants, other tests of cognitive function such as word learning, digit span and verbal fluency showed no beneficial effect of omega-3 PUFA supplementation. Participants in both the intervention and control groups experienced either small or

Physical frailty is associated with increased prevalence and incidence of cognitive impairment, and co-existing physical frailty and cognitive impairment confers additionally greater risk of incident NCD.
