Oral sildenafil, taken as required (not more than once daily), significantly improves the quality of erections and satisfaction with sex life in men with erectile dysfunction caused by a spinal cord injury between T6 and L5.

Data on the prevalence of malnutrition among patients with spinal cord injuries (SCI) are lacking. The aim of the present study was to assess nutritional risk at admission, and the status of nutritional support in the UK SCI Centres (SCIC); a cross-sectional, multicentre study in four SCIC. A standardised questionnaire was used and distributed to the participating SCIC. After obtaining informed consent, baseline demographic data, nutritional risk score by the 'Malnutrition Universal Screening Tool', BMI and routine blood biochemistry were collected from every patient admitted to an SCIC. The four SCIC, comprising 48·2 % of the total UK SCI beds, contributed data from 150 patients. On admission, 44·3 % of patients were malnourished or at risk of undernutrition. Nutritional risk was more common in patients with acute high cervical SCI than those with lower SCI (60·7 v. 34·5 %), and nutritional risk was more common in those with additional complications including ventilatory support (with tracheostomy, 56·3 v. 38·7 %). Also, 45 % of patients were at risk of overnutrition (BMI $ 25 kg/m 2 ). The prevalence of malnutrition in SCI patients admitted to SCIC is higher than national figures focused on general hospitalised patients, indicating that SCI patients are particularly vulnerable to malnutrition. Patients with SCI who have a tracheostomy may need additional attention. Given the potential negative impact of malnutrition on clinical outcomes, an emphasis on mandatory nutrition screening, followed by detailed assessment for at-risk individuals should be in place in the SCIC.

Background/Objectives: A disease-specific nutrition screening tool (NST): the spinal nutrition screening tool (SNST) has been developed for use in patients with spinal cord injury (SCI) but its reliability and agreement with other published tools requires investigation. The aims of this study were to assess the prevalence of malnutrition risk in SCI patients and to confirm the diagnostic accuracy of the SNST. Subjects/Methods: Patients' baseline clinical data, anthropometric measurements and NST scores were assessed. The validity of the SNST was assessed by (i) comparing with a full dietetic assessment (criterion validity); (ii) comparison with a generic NST: malnutrition universal screening tool (MUST) (concurrent validity); and (iii) completion of an additional SNST to assess inter-and intra-rater reliability. Agreement was assessed using Cohen's k-statistics. Results: Using the SNST, the prevalence of malnutrition risk ranged from 22 to 64% on admission to four SCI centres. The SNST had substantial agreement with MUST (k: 0.723, 95% confidence interval (CI): 0.607-0.839) and dietitian assessment (k: 0.567, 95% CI: 0.434-0.699). The SNST had a moderate to substantial reliability (inter-rater reliability: k: 0.5, 95% CI: 0.2-0.8; intra-rater reliability: k: 0.64, 95% CI: 0.486-0.802). When compared with dietetic assessment, the SNST had a numerically lower specificity (76.1% vs 80.4%) and similar agreement to MUST (k: 0.57 vs 0.58) but SNST showed a numerically higher sensitivity (85.7% vs 80.4%) and a numerically higher negative predictive value (92% vs 89.2%) than MUST. Conclusions: This study shows that malnutrition is common in SCI patients. The SNST is an acceptable (valid and reliable) NST and may be a useful alternative to MUST in identifying SCI patients at risk of malnutrition.

The present study suggests that undernutrition risk, as identified by the SNST, is associated with adverse clinical outcomes. Nutritional screening should be helpful in improving clinical outcomes if it promotes more appropriate and effective nutritional intervention.
