Association of covert brain infarcts and white matter hyperintensities with risk of hip fracture in older adults: the Cardiovascular Health Study.

Covert brain infarcts and white matter hyperintensities (WMHs), incidental markers of brain microvascular disease commonly seen on brain MRIs in older adults, have been associated with falls and lower bone mineral density. We found covert infarcts and WMHs may also be associated with an increased risk of future hip fracture. INTRODUCTION: To determine whether covert infarcts and white matter hyperintensities (WMHs) are associated with increased risk of incident hip fracture. METHODS: A prospective cohort of 3373 community-dwelling adults aged ≥ 65 years enrolled in the Cardiovascular Health Study with a brain MRI (1992-1993) was analyzed. Covert infarcts were categorized by number of infarcts and largest infarct size. WMH burden was assessed by radiologists and graded qualitatively from 0 (no WMHs) to 9 (extensive). RESULTS: Participants had 465 incident hip fractures during a mean follow-up of 12.8 years. The demographic-adjusted hazard of incident hip fracture was 32% higher among participants with ≥ 1 covert infarct compared to those without infarcts (hazard ratio (HR) 1.32; 95% CI, 1.08-1.62). The hazard of incident hip fracture was similar after further adjustment for medications and medical history (HR = 1.34; 95% CI, 1.08-1.65), but attenuated following additional adjustment for functional status, frailty, and falls (HR = 1.25; 95% CI, 0.99-1.57). Fully adjusted hazard of incident hip fracture per increase in infarct number was 1.10 (95% CI, 0.98-1.23); risk in individuals whose largest infarct was ≥ 20 mm versus 3 to < 20 mm was similar. Compared with WMH grades 0-1, the demographic-adjusted hazard of hip fracture was 1.34 (95% CI, 1.09-1.66) and 1.83 (95% CI, 1.37-2.46), respectively, for WMH grades 2-3 and 4-9. The hazard was similar following adjustment for medications and medical history (grades 2-3: HR = 1.32; 95% CI, 1.05-1.64; grades 4-9: HR = 1.69; 95% CI, 1.23-2.30), but attenuated following additional adjustment for functional status, frailty, and falls (grades 2-3: HR = 1.24; 95% CI, 0.98-1.56; grades 4-9: HR = 1.34; 95% CI, 0.95-1.90). CONCLUSION: Older, community-dwelling adults with covert infarcts or WMHs may be at increased risk of hip fracture.

The Importance of Person-Centered Approaches to Managing Behavioral and Psychological Symptoms of Dementia: A Case Report.

Behavioral and psychological symptoms of dementia (BPSD) are common and associated with increased morbidity and mortality in dementia. In this report, we describe a patient with severe BPSD who was effectively managed with a variety of non-pharmacologic strategies. A 70-year-old Navy veteran and retired commercial flooring business owner with a history of dementia was admitted to the hospital with aggressive behavior. He was no longer manageable by his family. He required intermittent use of restraints and multiple antipsychotics during hospitalization. He spent much of his time crawling on the floor, "working" on floor tiles, which was often difficult for staff to safely accommodate. However, with time, interprofessional staff identified signs of distress and developed strategies to safely engage the patient's current perception of his situation. This case highlights how BPSD may be driven by a person's identities and roles from earlier stages of life. Approaching and managing these symptoms flexibly can enhance dementia care.

COVID-19 postacute care major organ damage: a systematic review.

BACKGROUND: Major organ complications have been reported in patients hospitalised for COVID-19; most studies lacked controls. OBJECTIVE: Examine major organ damage postdischarge among adults hospitalised for COVID-19 versus non-COVID-19 controls. DATA SOURCES: MEDLINE, Embase and Cochrane Library from 1 January 2020 to 19 May 2021. STUDY ELIGIBILITY CRITERIA: English language studies of adults discharged from hospital for COVID-19; reporting major organ damage. Single review of abstracts; independent dual review of full text. STUDY APPRAISAL AND SYNTHESIS METHODS: Study quality was assessed using the Joanna Briggs Institute Appraisal Checklist for Cohort Studies. Outcome data were not pooled due to heterogeneity in populations, study designs and outcome assessment methods; findings are narratively synthesised. RESULTS: Of 124 studies in a full evidence report, 9 included non-COVID controls and are described here. Four of the nine (three USA, one UK) used large administrative databases. Four of the remaining five studies enrolled <600 COVID-19 patients. Mean or median age ranged from 49 to 70 years with 46%-94% male and 48%-78% White race; 10%-40% had been in intensive care units. Follow-up ranged from 4 weeks to 22 weeks postdischarge. Four used hospitalised controls, three non-hospitalised controls and two were unclear. Studies used various definitions of, and methods to assess, major organ damage outcomes. While the magnitude of effect differed across studies, incident cardiac, pulmonary, liver, acute and chronic kidney, stroke, diabetes, and coagulation disorders were consistently greater in adults hospitalised for COVID-19 compared with non-COVID-19 controls. LIMITATIONS: Applicability to subgroups (age, gender, COVID-19 severity, treatment, vaccination status) and non-hospitalised patients is unknown. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: Postacute COVID-19 major organ damage is common and likely higher than controls. However, there is substantial uncertainty. More consistent reporting of clinical outcomes and pre-COVID health status along with careful selection of control groups are needed to address evidence gaps.
