Bidirectional relationship between caregiver mastery and anxiety in individuals with cognitive impairment

Por: Ontan · M. S. · Isik · A. T.

Commentary on: Yeji Hwang, Miranda V. McPhillips, Liming Huang, G. Adriana Perez and Nancy A. Hodgson, Better caregiver mastery is associated with less anxiety in individuals with cognitive impairment, BMC Nursing. 2023; 22:307.

Implications for practice and research

  • Anxiety is one of the common neuropsychiatric symptoms (NPs) in individuals with cognitive impairment. Considering the fluctuating and variable course of NPs in dementia, studies with longer follow-up periods are required to understand the relationship between caregiver mastery and anxiety in patients with dementia.

  • Dementia, an umbrella condition, encompasses various neurogenerative diseases that can cause behavioural problems, movement problems, autonomic dysfunction, gait and balance problems, as well as cognitive impairment. Hence, it is important to develop caregiver skills with different strategies for each type of dementia.

  • Context

    As the population ages, the prevalence of dementia has increased.1 Due to interruption in activities of...

    Behaviours as biomarkers? Disentangling causality between vitamin D, sedentary behaviours and mortality is necessary for preventing recurrence and cardiovascular disease in cancer survivors

    Por: Giorgi Rossi · P. · Bonvicini · L.

    Commentary on: Yu Y, Cheng S, Huang H, et al. Joint association of sedentary behaviour and vitamin D status with mortality among cancer survivors. BMC Med 2023;21:411.

    Implications for practice and research

  • Results support National Institute for Health and Care Excellence recommendations7 in defining vitamin D levels below 50 nmol/L as insufficient and highlight sitting time over 6 hours/day as a possible determinant of mortality in cancer survivors.

  • Biological mediators linking sedentary behaviours, vitamin D and health outcomes should be investigated to understand the underlying causal link.

  • Context

    Many observational studies showed that sedentary behaviours1 and low serum levels of vitamin D2 are independent risk factors for mortality in cancer survivors. Nevertheless, data from trials on vitamin D supplementation3 and interventions promoting physical activity4 did not obtain the effect on mortality in cancer survivors that...
