Erythrocyte sedimentation rate and albumin as markers of inflammation are associated with measures of sarcopenia: a cross-sectional study.

BACKGROUND: Chronic inflammation is considered to affect physical performance, muscle strength and muscle mass, i.e. measures of sarcopenia. We need to identify a marker of inflammation that is univocally associated with measures of sarcopenia. We aimed to associate three markers of inflammation, erythrocyte sedimentation rate, albumin and white blood cell count, with measures of sarcopenia in geriatric outpatients. METHODS: Data from the Centre Of Geriatrics Amsterdam cohort was used. Geriatric outpatients at the VU university medical centre in Amsterdam were recruited based on referral between January 1st 2014 and the 31st of December 2015. Erythrocyte sedimentation rate, albumin and white blood cell count were assessed from venous blood samples. Measures of sarcopenia included physical performance by measuring gait speed with the 4 meter walk test, duration of the timed up and go test and of the chair stand test, muscle strength by assessing handgrip strength using handheld dynamometry and skeletal muscle mass by performing bioelectrical impedance analysis. Multivariable linear regression analyses were performed to assess the associations between erythrocyte sedimentation rate, albumin, white blood cell count and measures of sarcopenia. RESULTS: A total of 442 patients (mean age 80.8 years, SD 6.7, 58.1% female) were included. A higher erythrocyte sedimentation rate was significantly associated with lower gait speed (ß = - 0.005; 95% CI = - 0.007, - 0.003), longer duration of timed up and go test (Ln ß = 0.006; 95% CI = 0.003, 0.010), longer duration of chair stand test (Ln ß = 0.005; 95% CI = 0.002, 0.008), lower handgrip strength (ß = - 0.126; 95% CI = - 0.189, - 0.063) and lower relative skeletal muscle mass (ß = - 0.179; 95% CI = - 0.274, - 0.084). Lower albumin levels were significantly associated with lower gait speed (ß = - 0.020; 95% CI = - 0.011, - 0.028) and handgrip strength (ß = - 0.596; 95% CI = - 0.311, - 0.881). Associations remained significant after adjustment for age, sex and number of morbidities. No significant associations were found for white blood cell count and measures of sarcopenia. CONCLUSIONS: In geriatric outpatients, erythrocyte sedimentation rate was associated with all three measures of sarcopenia, underpinning the potential role of inflammation in sarcopenia.

Advance Care Planning in Dutch Nursing Homes During the First Wave of the COVID-19 Pandemic.

OBJECTIVES: To explore how physicians in Dutch nursing homes practiced advance care planning (ACP) during the first wave of the COVID-19 pandemic, and to explore whether and how ACP changed during the first wave of the pandemic. DESIGN: Qualitative analysis of an online, mainly open-ended questionnaire on ACP among physicians working in nursing homes in the Netherlands during the first wave of the COVID-19 pandemic. SETTING AND PARTICIPANTS: Physicians in Dutch nursing homes. METHODS: Respondents were asked to describe a recent case in which they had a discussion on anticipatory medical care decisions and to indicate whether ACP was influenced by the COVID-19 pandemic in that specific case and in general. Answers were independently coded and a codebook was compiled in which the codes were ordered by themes that emerged from the data. RESULTS: A total of 129 questionnaires were filled out. Saturation was reached after analyzing 60 questionnaires. Four main themes evolved after coding the questionnaires: reasons for ACP discussion, discussing ACP, topics discussed in ACP, and decision making in ACP. COVID-19-specific changes in ACP indicated by respondents included (1) COVID-19 infection as a reason for initiating ACP, (2) a higher frequency of ACP discussions, (3) less face-to-face contact with surrogate decision makers, and (4) intensive care unit admission as an additional topic in anticipatory medical decision making. CONCLUSIONS AND IMPLICATIONS: ACP in Dutch nursing homes has changed because of the COVID-19 pandemic. Maintaining frequent and informal contact with surrogate decision makers fosters mutual understanding and aids the decision-making process in ACP.
