Working status is related to post stroke/TIA cognitive decline: data from the TABASCO study

White Matter Microstructural Alterations over the Year after Acute Ischemic Stroke in Patients with Baseline Impaired Cognitive Functions

Background

The disruption of white matter (WM) integrity is related to poststroke cognitive impairment (PSCI). The exploration of WM integrity alterations in the chronic stage of acute ischemic stroke (AIS) may help to improve the long-term outcomes of PSCI.

Methods

Sixty patients showing impaired cognitive functions within 3 days after AIS (baseline) and 25 healthy controls underwent diffusion kurtosis imaging scan and cognitive assessment at baseline and 1 year. Based on the tract-based spatial statistics (TBSS), kurtosis fractional anisotropy (KFA) and mean kurtosis (MK) were compared in WM tracts between the groups.

Results

One year after AIS, 25 patients were diagnosed with PSCI and 35 patients with non-cognitive impairment (NCI). Compared with baseline, cognitive performance improved in 54 patients and remained unchanged in 6 patients at 1 year. TBSS analysis showed that there were no significant differences in WM tract integrity between the AIS and control groups at baseline (P > 0.05). Compared with the control group, the KFA and MK in multiple WM tracts in the AIS group decreased significantly at 1 year (P < 0.05). Longitudinal analysis showed that the KFA and MK of multiple WM tracts recorded at 1 year were significantly lower than those recorded at baseline in the AIS, PSCI, and NCI groups (P < 0.05), and PSCI group had a faster degeneration than NCI group (P < 0.05).

Conclusion

The finding suggests that the patients with baseline impaired cognitive functions still have WM microstructural damages at 1 year poststroke, even if their cognitive function has improved or returned to normal. Cautions should be taken against the possible negative impact of these changes on long-term cognition.

Factors associated with work ability in adults with diabetes

AIMS

The aims of this study were to explore associations between clinical and diabetes-related factors with work ability in a sample of working adults with diabetes.

BACKGROUND

Adults with diabetes may face challenges in the workplace, including managing their diabetes and overall physical and mental health.

METHODS

This was a cross-sectional design with a sample of 101 working adults. Subjects completed valid and reliable surveys assessing depressive symptoms, diabetes self-care, fear of hypoglycemia, diabetes distress, cardiovascular health using American Heart Association's Life's Simple 7 (range 0-7) and work ability. Factors significantly associated with work ability at bivariate level were included in linear and logistic regression.

RESULTS

The majority of the sample was female (65%) (mean age 54.1 ± 10.5), White (74%), non-Hispanic (93%), worked full-time (65%) and had type 2 diabetes (87%) (mean duration 12.4 ± 9.5 years). The majority (55%) had low diabetes distress, but 24% had high distress and 28% had depressive symptoms. The sample achieved 2.5 ± 1.4 ideal AHA heart health indices and 33% rated their work ability as excellent. In linear regression higher depressive scores were associated with lower work ability scores (b = -0.45, p = .002). In logistic regression, scores on heart health (OR = 1.4; 95%CI:1.0-1.9, p = .03) and diabetes distress (OR = 0.6, 95%CI:0.4-0.9, p = .048) were significantly associated with work ability at its best.

CONCLUSION

Both cardiovascular and psychological health may impact work ability in adults with diabetes. Routinely screening for diabetes distress and depression while also promoting ideal cardiovascular health may improve overall health and work ability in this population.
