Development and Validation of a Novel Nomogram to Predict Hypoalbuminemia among Patients with Stroke in the Neurocritical Care Unit

This study aimed to investigate hypoalbuminemia-related factors in patients with stroke in the neurocritical care unit (NCU) and to establish a nomogram model for hypoalbuminemia prediction. Data from 902 patients hospitalized for stroke in the NCU who had normal albumin levels on admission from March 2018 to December 2020 were analyzed. Logistic regression was used to identify the risk factors associated with hypoalbuminemia. A novel nomogram prediction model for hypoalbuminemia was constructed, and it was validated in an independent set (n = 233). The nomogram incorporated seven risk factors, including age, high comorbidity, mechanical ventilation, feeding routes, total protein, high-sensitivity C-reactive protein, and fibrinogen levels, and its area under the curve for predicting hypoalbuminemia in the developmental set and validation set were 0.856 and 0.870, respectively. The novel nomogram facilitates risk prediction of hypoalbuminemia among patients with stroke in the NCU, which might be useful for selecting treatment strategies and management.

Chinese expert consensus on prevention and intervention for the elderly with malnutrition (2022)

Malnutrition is a state of altered body composition and body cell mass due to inadequate intake or utilization of energy or nutrients, leading to physical and mental dysfunction and impaired clinical outcomes. As one of the most common geriatric syndromes, malnutrition in the elderly is a significant risk factor for poor clinical outcomes, causing a massive burden on medical resources and society. The risk factors for malnutrition in the elderly are diverse and include demographics, chronic diseases, and psychosocial factors. Presently, recommendations for the prevention and intervention of malnutrition in the elderly are not clear or consistent in China. This consensus is based on the latest global evidence and multiregional clinical experience in China, which aims to standardize the prevention and intervention of malnutrition in the elderly in China and improve the efficacy of clinical practice and the prognosis of elderly patients.

The effect of enteral versus parenteral nutrition for critically ill patients: A systematic review and meta-analysis

STUDY OBJECTIVE

To analyze the effect of enteral nutrition compared with parenteral nutrition in critically ill patients.

DESIGN

Systematic review and meta-analysis of randomized controlled trials.

SETTING

Intensive care unit.

PATIENTS

23 trials containing 6478 patients met our inclusion criteria.

INTERVENTION

A systematical literature search was conducted to identify eligible trials in electronic databases including PubMed, Embase, Scopus, EBSCO and Cochrane Library. The primary outcome was mortality, the secondary outcomes were gastrointestinal complications, bloodstream infections, organ failures, length of stay in ICU and hospital. We performed a predefined subgroup analyses to explore the treatment effect by mean age, publication date and disease types.

MAIN RESULTS

The result showed no significant effect on overall mortality rate (OR 0.98, 95%CI 0.81 to 1.18, P = 0.83, I² = 19%) and organ failure rate (OR 0.87, 95%CI 0.75 to 1.01, P = 0.06, I² = 16%). The use of EN had more beneficial effects with fewer bloodstream infections when compared to PN (OR 0.59, 95%CI 0.43 to 0.82, P = 0.001, I² = 27%) and this was more noteworthy in the subgroup analysis for critical surgical patients (OR 0.36, 95%CI 0.22 to 0.59, P < 0.0001, I² = 0%). EN was associated with reduction in hospital LOS (MD -0.90, 95%CI -1.63 to -0.17, P = 0.21, I² = 0%) but had an increase incidence of gastrointestinal complications (OR 2.00, 95%CI 1.76 to 2.27, P < 0.00001, I² = 0%).

CONCLUSION

For critically ill patients, the two routes of nutrition support had no different effect on mortality rate. The use of EN could decrease the incidence of bloodstream infections and reduce hospital LOS but was associated with increased risk of gastrointestinal complications.
