Predictive equations over estimating resting metabolic rate in individual with spinal cord injury requiring mechanical ventilation support - A case series.

Context: The impact of mechanical ventilation on energy expenditure after spinal cord injury (SCI) is sparse. The objective of this case-series is to measure 15-minutes resting metabolic rate (RMR) to determine 24-hours measured-RMR (m-RMR) using QUARK indirect calorimeter (IC) and; compare the m-RMR with estimated RMR (e-RMR) using four commonly used predictive equations (Harris-Benedict, Mifflin St-Jeor, Henry and Schofield).Findings: We measured the RMR of four patients with SCI (one male and three female; mean age: 58.3 years) all with complete tetraplegia (ISNCSCI A) twice in a one-week interval using an IC with two sampling flow settings during a six month period. The median (IQ) of all m-RMRs was 1094 (340.2) kcal/day. The median m-RMR was 40.1% lower than the median calculated with four different e-RMRs using predictive equations. All four predictive equations overestimated RMR in SCI patients requiring mechanical ventilation by 4.1-61.1% (Harris-Benedict: 28.8-60.6%; Mifflin St-Jeor: 6.9-61.1%; Henry: 4.1-58.9% and; Schofield: 6-54.6%).Conclusion/clinical relevance: There is a high variability of e-RMR and m-RMR in patients with SCI who are dependent on mechanical ventilation. The use of predictive equations may lead to over-estimation of energy requirements. To avoid overfeeding we recommended measuring RMR using IC wherever possible. A further study with a larger sample size is needed due to the small number of subjects in our case-series. Development of a validated RMR equation in the SCI population is warranted.

Detecting malnutrition risk and obesity after spinal cord injury: a quality improvement project and systematic review.

BACKGROUND/OBJECTIVES: Malnutrition and overweight are a major concern after spinal cord injury (SCI). There is limited information available for prevalence of malnutrition, overweight and nutrition screening compliance. The aim of this study is to (1) determine whether the quality improvement initiative is successful in improving nutrition screening and to (2) systematic review the literature on prevalence of malnutrition and overweight after SCI. SUBJECTS/METHODS: The quality improvement project was conducted during November 2013 to October 2017. Nutrition screening data (presence of a correctly completed Spinal Nutrition Screening Tool (SNST) within 24 h of admission) were collected weekly. Literatures on disease-related malnutrition prevalence in adult SCI patients published from inception to 17 March 2017 were included in the systematic review. RESULTS: Two thousand four hundred and sixty-two SCI (49.3% tetraplegia; 47.6% complete SCI) patients (mean age: 76.7 ± 16.2 years, 70.6% men) were included. Nutrition screening compliance increased significantly overtime (2013-2014: 49.3%; 2014-2015: 69.7%; 2015-2016: 80.7%; 2016-207: 76.7%, p < 0.01). Eighty-four articles were identified from the systematic review, of these nine studies with 9265 SCI patients were included. There was considerable variability in methodology and prevalence of malnutrition risk (three nutrition screening tools were reported: body mass index (BMI); Malnutrition Universal Screening Tool; SNST). The prevalence of undernutrition was in the range of 40-50%. Three different BMI cutoffs were reported as overweight's cut-off (>22, >23 and >25 kg/m2). The prevalence of overweight was in the range of 45-69.2%. CONCLUSIONS: Malnutrition and overweight is a highly prevalent condition after SCI. Further research is warranted to characterise screening practices and identify evidence-based interventions to this ongoing and costly clinical and public health issue.

Effectiveness of probiotic in preventing and treating antibiotic-associated diarrhoea and/or Clostridium difficile-associated diarrhoea in patients with spinal cord injury: a protocol of systematic review of randomised controlled trials.

BACKGROUND: Probiotics may prevent antibiotic-associated and Clostridium difficile-associated diarrhoea (AAD/CDAD). Many spinal cord injury centre (SCIC) practitioners consider probiotics generically and may not realise that efficacy can be strain-, dose- and disease-specific. In order to confirm these effects and fully evaluate the extent of probiotic effectiveness in these patients, a systematic review and meta-analysis is indicated. METHODS: The following databases will be searched for relevant studies: Cochrane Library; Centre for Reviews and Dissemination (CRD) Database; CINAHL; PsycINFO; Embase; Medline; AMED; International Clinical Trials Registry Platform Search Portal and ISRCTN Registry and will hand search a list of conference proceedings. Any randomised controlled trials without restriction of publication status will be included with treatment of AAD/CDAD. Outcomes will include the effect of probiotic on the occurrence of AAD/CDAD and duration of diarrhoea, intensive care unit admission, hospital mortality and length of hospital stay. Two reviewers will independently screen the titles, abstracts or even full texts and extract data. Two other reviewers will assess study quality. Revman 5.1 software will be used to conduct meta-analysis and calculate the risk ratio for dichotomous data. Weighted mean difference or standard mean difference will be calculated for continuous data. The Cochrane Collaboration's tool will be used to assess the risk of bias. DISCUSSION: This systematic review protocol will provide information on probiotic therapy for AAD and CDAD in spinal cord injury (SCI) population. The results will be disseminated through peer-reviewed publication or conference presentation. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015016976.
