Dear editor
Newly, we had paid attention to the published paper entitled “Predictive Value of Nutritional Risk for All-Cause Death and Functional Outcomes in Chinese Elderly Patients with Acute Stroke: A 3-Year Follow-Up Study” by Cong WJ team in Clinical Interventions in Aging.1 We appreciate this study and congratulate them on their performance.
This study explored the predictive value of nutritional risk for all-cause mortality and functional outcomes in elderly patients with acute stroke. Based on the nutritional risk screening 2002 (NRS-2002) and geriatric nutritional risk index (GNRI), the primary all-cause mortality endpoint event and the secondary poor prognosis outcome were assessed in a total of 479 elderly patients with acute stroke. They found that patients with moderate and severe malnutrition had a higher risk of all-cause death at 3 months and at 3 years and a higher risk of adverse functional outcomes at 3 months. They concluded that nutritional risk increased the risk of poor short-term and long-term endpoint events in elderly patients with acute stroke.
We believe that only by improving the following points can the conclusions of this study have a stronger guiding effect on routine clinical practice. Firstly, absence of information on Vitamin D levels in participants. Regardless of conventional risk factors, vitamin D insufficiency, especially its severe form, is related to an elevated risk of cardiovascular events (stroke, coronary heart disease, and mortality).2 Notably, it is pretty typical for older Chinese people to be deficient in vitamin D.3 Additionally, absence of information on bone metabolism. Osteoporosis is a twin disease with stroke.4 Meanwhile, osteosarcopenia caused by decreased appetite is closely related to malnutrition.5
Although we applaud this research work, we still believe that only further improving the research design can obtain more convincing conclusions.
