Association between anticoagulant therapy, exacerbations and mortality in a Danish cohort of patients with Chronic Obstructive Pulmonary Disease.

OBJECTIVES: Pulmonary Embolism has been frequently reported in Acute Exacerbations of Chronic Obstructive Pulmonary Disease (AE-COPD). The study aimed to determine whether COPD patients who receive anticoagulant (AC) therapy have a reduced risk of hospitalization due to AE-COPD and death. METHODS: This nationwide population-based study was based on data from the Danish Register of COPD (DrCOPD), which contains complete data on COPD outpatients between 1st January 2010 and 31st December 2018. National registers were used to obtain information regarding comorbidities and vital status. Propensity-score matching and Cox proportional hazards models were used to assess AE-COPD and death after one year. RESULTS: The study cohort consisted of 58,067 patients with COPD. Of these, 5194 patients were on AC therapy. The population was matched 1:1 based on clinical confounders and AC therapy, resulting in two groups of 5180 patients. We found no association between AC therapy and AE-COPD or all-cause mortality in the propensity-score matched population (HR 1.03, 95% CI 0.96-1.10, p = 0.37). These findings were confirmed in a competing risk analysis. In the sensitivity analysis, we performed an adjusted analysis of the complete cohort and found a slightly increased risk of AE-COPD or death in patients treated with AC therapy. This study found a low incidence of pulmonary embolisms and deep venous thrombosis in both groups. CONCLUSIONS: AC therapy was not associated with the risk of hospitalization due to AE-COPD or all-cause mortality.

Assessment of autonomic function after acute spinal cord injury using heart rate variability analyses.

OBJECTIVES: Spinal cord injury (SCI) often results in severe dysfunction of the autonomic nervous system. C1-C8 SCI affects the supraspinal control to the heart, T1-T5 SCI affects the spinal sympathetic outflow to the heart, and T6-T12 SCI leaves sympathetic control to the heart intact. Heart rate variability (HRV) analysis can serve as a surrogate measure of autonomic regulation. The aim of this study was to investigate changes in HRV patterns and alterations in patients with acute traumatic SCI. METHODS: As soon as possible after SCI patients who met the inclusion criteria had 24 h Holter monitoring of their cardiac rhythm, additional Holter monitoring were performed 1, 2, 3 and 4 weeks after SCI. RESULTS: Fifty SCI patients were included. A significant increase in standard deviation of the average normal-to-normal (SDANN) sinus intervals was seen in the first month after injury (P=0.008). The increase was only significant in C1-T5 incomplete patients and in patients who did not experience one or more episodes of cardiac arrest. Significant lower values of Low Frequency Power, Total Power and the Low Frequency over High Frequency ratio were seen in the C1-T5 SCI patients compared with T6-T12 SCI patients. CONCLUSIONS: The rise in SDANN in the incomplete C1-T5 patients could be due to spontaneous functional recovery caused by synaptic plasticity or remodelling of damaged axons. That the autonomic nervous system function differs between C1-C8, T1-T5 and T6-T12 patients suggest that the sympathovagal balance in both the C1-C8 and T1-T5 SCI patients has yet to be reached.

Home aids and personal assistance 10-45 years after spinal cord injury.

OBJECTIVE: Assessment of home aids, adaptations and personal assistance received after traumatic spinal cord injury (SCI). SETTING: Clinic for Spinal Cord Injuries, Denmark. Uptake area, 2.5 million inhabitants. STUDY DESIGN AND METHODS: Cross-sectional follow-up with retrospective data from medical files. MATERIALS: Individuals with traumatic SCI before 1 January 1991, still in regular follow-up and with sufficient medical record. In all, 279 were included, and 236 answered the questionnaire (193 men and 43 women), with a response rate of 84.6%. Mean age at follow-up was 50.5 years, and mean follow-up time, 24.1 years. One hundred and twenty-six were paraplegic and 110, tetraplegic. Responders and non-responders were comparable. RESULTS: Most common aids or adaptations reported were commode/shower chair on wheels or a seat (69%), grab bar by the toilet (41%), electrical bed (44%), special mattress (28%), lift/hoist (20%), computers (39%) and kitchen tools or cutlery with special handles (14%). In all, 7.6% of the participants reported no aids. Eighty-two percent answered 'Yes' to the question 'Have the aids, you currently or previously needed, been available to you?' The majority reported that their source of information about aid had been various journals and magazines. Twenty-one percent had personal helpers, with 60 h per week in median (range 2-168). Thirty-three percent received domestic help with 2.5 h per week in median (range 0.5-37). Eight percent had a home nurse. A total of 98.7% were living in their own homes. CONCLUSIONS: This is the first study of a representative SCI population giving information on home aids. Individuals with SCI in Denmark seem to be sufficiently supplied with aids and personal assistance.
