IntroductionAlterations in taste and smell are among the most distressing symptoms experienced by haemodialysis patients. There is limited research on the relationship between these two symptoms and malnutrition in haemodialysis patients. This study aimed to investigate alterations in taste and smell in hemodialysis patients and their relationship with malnutrition.MethodsThis cross‐sectional study was carried out with 149 hemodialysis patients at the dialysis centers of three state hospitals. The Taste and Smell Dysfunction Questionnaire was used to assess the changes in patients' taste and smell, and the Prognostic Nutritional Index (PNI), as well as the Controlling Nutritional Status (CONUT) tool, were utilized to evaluate their nutritional status.FindingsA substantial percentage (45.6%) of patients reported an altered sense of smell, and 40.2% reported an altered sense of taste. The aspect of taste that was most abnormal was bitterness (46.7%); 53.0% of the patients were at moderate risk of malnutrition by PNI score, and 14.8% were categorized as malnourished by CONUT score. Malnutrition was related to dialysis vintage: a 1‐year increase in vintage was associated with an increased risk of malnutrition (OR: 1.17, 95% CI 1.02–1.32, p < 0.001). Altered taste was associated with malnutrition: one‐unit increase in the standard deviation of the taste subdimension score was associated with a relative risk of malnutrition (OR: 6.89, 95% CI 1.67–28.39, p < 0.001). A one‐unit increase in the standard deviation of the smell subdimension was associated with relative risk of malnutrition (OR: 1.35, 95% CI 1.10–1.64, p < 0.001).DiscussionMalnutrition was found in a significantpercentage of hemodialysis patients. Altered taste and smell and the durationof dialysis treatment were significantly associated with malnutrition scores It isrecommended that healthcare professionals regularly assess alterations in tasteand smell in hemodialysis patients, as these alterations may be associated withmalnutrition, and manage these alterations accordingly.

“…On the other hand, the total lymphocyte count (≤1500 cells/mm 3 ) may have a few limits due to other possible biasing conditions (i.e., hematological or infective diseases); however, recent studies on COVID have associated the total lymphocyte count with worse hospital outcomes and mortality in a context of severe inflammation [ 32 , 34 ]. Regarding total cholesterol, previous studies have associated low plasmatic levels with poor nutritional intake, systemic inflammation, and a worse prognosis in hospitalized patients, thus demonstrating a potential predictive value [ 35 , 36 ].…”

COntrolling NUTritional Status (CONUT) as Predictive Score of Hospital Length of Stay (LOS) and Mortality: A Prospective Cohort Study in an Internal Medicine and Gastroenterology Unit in Italy

Background: Hospital malnutrition affects nearly 30% of patients in medical wards and correlates with worse outcomes. An early assessment is necessary to stratify the risk of short-term outcomes and mortality. The predictive role of COntrolling NUTritional status (CONUT) score in this context has not yet been elucidated in Western countries. We aimed to test CONUT at admission as a predictive score of hospital outcomes, in an Internal Medicine and Gastroenterology Department of an Italian Tertiary Care University hospital. Methods: We prospectively enrolled patients admitted to our center, stratifying them into the four CONUT classes (normal = 0–1; mild = 2–4; moderate = 5–8; severe = 9–12 points) according to serum albumin (g/dL), total lymphocyte count (/mm3), and total cholesterol (mg/dL); the primary outcome measure was length of stay (LOS) and the secondary one was in-hospital mortality. Results: Out of a total of 203 patients enrolled, 44 (21.7%) patients had a normal status (0–1), 66 (32.5%) had a mild impairment (2–4), 68 (33.5%) had a moderate impairment (5–8), and 25 (12.3%) a severe impairment (9–12). The mean LOS was 8.24 ± 5.75 days; nine patients died. A moderate-severe CONUT correlated with a higher LOS at the univariate [HR 1.86 (95% CI 13.9–3.47); p < 0.0001] and multivariate analysis [HR 1.52 (95% CI 1.10–2.09); p = 0.01]. The CONUT score was also a predictor of mortality, with an AUC of 0.831 (95% CI 0.680–0.982) and with an optimal cut-off at 8.5 points. Nutritional supplementation within 48 h from admission correlated with lower mortality [OR 0.12 (95% CI 0.02–0.56) p = 0.006]. Conclusions: CONUT is a reliable and simple predictor of LOS and in-hospital mortality in medical wards.
