RESUMO
INTRODUCTION: Spinal infection (SI) is uncommon and patients present with varied clinical features. In this review, the presentation, investigation, treatment and outcome of patients with SI in the north-east of Scotland were assessed. METHODS: Electronic medical records of adult patients with SI hospitalised at a health board in the north-east of Scotland between 2014 and 2018 were analysed retrospectively. Collected variables included demographics, presenting clinical features, risk factors, comorbidities, admission blood results, microbiological investigations, imaging, treatment and outcomes. RESULTS: Seventy-two patients were included. Mean age (±sd) was 63.3 years (±14.5). The lumbar spine was the most commonly involved region (51.4%). Back pain (84.7%), altered mobility (33.3%) and fever (29.2%) were the most frequent presenting features. Thoracic spine involvement (p = 0.041), urinary symptoms (p = 0.033), cauda equina syndrome (CES) (p = 0.027) and limb weakness (p = 0.026) were associated with poorer outcome. A better outcome was associated with back pain at presentation (p = 0.03) and underlying malignancy (p = 0.045). Diabetes (15.3%), recent falls (15.3%) and immunosuppression (12.5%) were common. A likely causative organism was found in 54 patients (75.0%) and Staphylococcus aureus was isolated in 41.7% of patients. Penicillins were used in 56.3% of patients and 20.8% underwent surgery. Outcomes were full recovery (38.2%), residual symptoms or neurological deficits (50.0%), paraplegia (4.4%) and death (7.4%). CONCLUSIONS: Poorer outcomes occurred in patients with thoracic disease, limb weakness, urinary symptoms or CES, whereas better outcomes were associated with the presence of back pain on presentation and malignancy. This analysis highlights the diagnostic and therapeutic challenges of SI, alerting clinicians to key factors associated with prognosis.

BACKGROUND AND PURPOSE: The relationship of the estimated glomerular filtration rate (eGFR) with complications after stroke has not been fully characterized for the entire clinical spectrum of eGFR and for the fluctuation in eGFR during hospital stay. METHODS: Data from the Norfolk and Norwich Stroke Registry recorded between January 2003 and April 2015 were analysed. eGFR was categorized into six clinically relevant categories as per the Kidney Disease Improving Global Outcomes guidelines. The change in eGFR during acute admission was categorized into the following: within 5% change (reference), 5%-20% decline, >20% decline, 5%-20% increase and >20% increase. All-cause mortality, recurrent stroke, incident myocardial infarction, prolonged hospital stay and stroke disability at discharge were outcomes of interest. RESULTS: In all, 10 329 stroke patients (mean age 77.8 years) were followed for a mean of 2.9 years (30 126 person-years). Multivariable adjusted hazard ratios (95% confidence interval) for all-cause mortality were 0.91 (0.80-1.04), 0.96 (0.83-1.11), 1.23 (1.06-1.43), 1.54 (1.31-1.82) and 2.38 (1.91-2.97) for eGFR levels 60-89, 45-59, 30-44, 15-29 and <15 respectively, compared to eGFR ≥ 90 ml/min/1.73 m2 . The hazard ratios (95% confidence interval) for eGFR change were 1.56 (1.36-1.79), 1.17 (1.05-1.30), 1.47 (1.32-1.62) and 1.71 (1.55-1.88) for >20% decline, 5%-20% decline, 5%-20% increase and >20% increase, respectively, compared to change within 5%. Results were similar for other outcomes except recurrent stroke. CONCLUSIONS: Stroke patients with eGFR < 45 ml/min/1.73 m2 at hospital admission and >5% decline or increase in eGFR during hospital stay were at substantially higher risk of poor outcomes, particularly all-cause mortality, myocardial infarction, prolonged hospital stay and disability at discharge.

OBJECTIVES: Stroke-associated pneumonia (SAP) is common and associated with adverse outcomes. Data on its impact beyond 1 year are scarce. MATERIALS AND METHODS: This observational study was conducted in a cohort of stroke patients admitted consecutively to a tertiary referral center in the east of England, UK (January 2003-April 2015). Logistic regression models examined inpatient mortality and length of stay (LOS). Cox regression models examined longer-term mortality at predefined time periods (0-90 days, 90 days-1 year, 1-3 years, and 3-10 years) for SAP. Effect of SAP on functional outcome at discharge was assessed using logistic regression. RESULTS: A total of 9238 patients (mean age [±SD] 77.61 ± 11.88 years) were included. SAP was diagnosed in 1083 (11.7%) patients. The majority of these cases (n = 658; 60.8%) were aspiration pneumonia. After controlling for age, sex, stroke type, Oxfordshire Community Stroke Project (OCSP) classification, prestroke modified Rankin scale, comorbidities, and acute illness markers, mortality estimates remained significant at 3 time periods: inpatient (OR 5.87, 95%CI [4.97-6.93]), 0-90 days (2.17 [1.97-2.40]), and 91-365 days (HR 1.31 [1.03-1.67]). SAP was also associated with higher odds of long LOS (OR 1.93 [1.67-2.22]) and worse functional outcome (OR 7.17 [5.44-9.45]). In this cohort, SAP did not increase mortality risk beyond 1 year post-stroke, but it was associated with reduced mortality beyond 3 years. CONCLUSIONS: Stroke-associated pneumonia is not associated with increased long-term mortality, but it is linked with increased mortality up to 1 year, prolonged LOS, and poor functional outcome on discharge. Targeted intervention strategies are required to improve outcomes of SAP patients who survive to hospital discharge.

OBJECTIVES: To examine the usefulness of including sodium (Na) levels as a criterion to the SOAR stroke score in predicting inpatient and 7-day mortality in stroke. MATERIALS AND METHODS: Data from the Norfolk and Norwich University Hospital Stroke & TIA register (2003-2015) were analysed. Univariate and then multivariate models controlling for SOAR variables were used to assess the association between admission sodium levels and inpatient and 7-day mortality. The prognostic ability of the SOAR and SOAR Na scores for mortality outcomes at both time points were then compared using the Area Under the Curve (AUC) values from the Receiver Operating Characteristic curves. RESULTS: A total of 8493 cases were included (male=47.4%, mean (SD) 77.7 (11.6) years). Compared with normonatremia (135-145 mmol/L), hypernatraemia (>145 mmol/L) was associated with inpatient mortality and moderate (125-129 mmol/L) and severe hypontraemia (<125 mmol/L) with 7-day mortality after adjustment for stroke type, Oxfordshire Community Stroke Project classification, age, prestroke modified Rankin score and sex. The SOAR and SOAR-Na scores both performed well in predicting inpatient mortality with AUC values of .794 (.78-.81) and .796 (.78-.81), respectively. 7-day mortality showed similar results. Both scores were less predictive in those with chronic kidney disease (CKD) and more so in those with hypoglycaemia. CONCLUSION: The SOAR-Na did not perform considerably better than the SOAR stroke score. However, the performance of SOAR-Na in those with CKD and dysglycaemias requires further investigation.
