OBJECTIVE: To investigate the relationship between malnutrition and delirium and its effect on prognosis in elderly patients with severe pneumonia undergoing invasive mechanical ventilation. METHODS: A prospective observational study was conducted. Patients with severe pneumonia aged ≥ 60 years old who underwent invasive mechanical ventilation admitted to department of critical care medicine of the Second People's Hospital of Lianyungang from January 2021 to December 2022 were enrolled. The confusion assessment method (CAM) was used to evaluate the delirium of the patients in intensive care unit (ICU). The score of CAM ≥ 1 was defined as delirium. Mini nutritional assessment short-form (MNA-SF) was used to assess the nutritional status of patients, and MNA-SF score ≤ 7 was defined as malnutrition. Patients were divided into delirium group and non-delirium group according to whether delirium occurred. The differences in clinical indicators, length of ICU stay, duration of mechanical ventilation and wake-up time after drug withdrawal were compared between the two groups. After 28 days of short-term follow-up, the patients were divided into death group and survival group, and the differences in the incidence of delirium and malnutrition between the two groups were compared. Binary multivariate Logistic regression analysis was used to screen the risk factors for delirium in elderly patients with severe pneumonia undergoing invasive mechanical ventilation. Kaplan-Meier survival curve was used to analyze the effect of delirium on prognosis. RESULTS: A total of 132 elderly patients with severe pneumonia undergoing invasive mechanical ventilation were enrolled, of whom 98 survived and 34 died within 28 days, with a mortality of 25.76%. The incidence of malnutrition and delirium in the death group was significantly higher than that in the survival group (61.76% vs. 37.76%, 64.71% vs. 26.53%, both P < 0.05), and the MNA-SF score was significantly lower than that in the survival group (6.32±1.80 vs. 8.72±2.23, P < 0.01). Procalcitonin (PCT), interleukin-6 (IL-6) and blood lactic acid (Lac) in the death group were significantly higher than those in the survival group [PCT (μg/L): 4.47 (2.69, 10.39) vs. 2.77 (1.28, 5.94), IL-6 (ng/L): 204.08 (126.12, 509.85) vs. 120.46 (60.67, 290.99), Lac (mmol/L): 5.14 (2.75, 8.60) vs. 3.13 (2.16, 4.30), all P < 0.05], and the wake-up time after drug withdrawal was significantly longer than that in the survival group (minutes: 33.94±8.51 vs. 28.92±7.03, P < 0.01). Among 132 elderly patients with severe pneumonia undergoing invasive mechanical ventilation, 48 patients had delirium during ICU stay, and 84 patients did not have delirium. The incidence of delirium was 36.36%. The 28-day mortality in the delirium group was significantly higher than that in the non-delirium group (45.83% vs. 14.29%, P < 0.01), and the MNA-SF score was significantly lower than that in the non-delirium group (6.46±1.77 vs. 9.05±2.15, P < 0.01), the length of ICU stay, duration of mechanical ventilation, and wake-up time after drug withdrawal were also significantly longer than those in the non-delirium group [length of ICU stay (days): 13.40±9.59 vs. 10.06±7.81, duration of mechanical ventilation (hours): 197.06±89.80 vs. 138.81±82.30, wake-up time after drug withdrawal (minutes): 35.85±7.01 vs. 26.99±6.12, all P < 0.05]. Binary multivariate Logistic regression analysis showed that malnutrition [odds ratio (OR) = 7.527, 95% confidence interval (95%CI) was 2.585-21.917], Lac (OR = 5.345, 95%CI was 1.733-16.483), wake-up time after drug withdrawal (OR = 6.653, 95%CI was 2.021-21.904) were independent risk factors for delirium during ICU stay in elderly patients with severe pneumonia undergoing invasive mechanical ventilation (all P < 0.01). Kaplan-Meier survival analysis showed that the 28-day cumulative survival rate of patients in the delirium group was significantly lower than that in the non-delirium group (54.17% vs. 85.71%), and the difference was statistically significant (Log-Rank test: χ² = 16.780, P < 0.001). CONCLUSIONS The risk factors for delirium in elderly patients with severe pneumonia undergoing invasive mechanical ventilation during ICU stay include malnutrition, Lac, and wake-up time after drug withdrawal. The occurrence of delirium is closely related to poor prognosis.

OBJECTIVE: To explore the influence of nutritional status on 90-day functional outcomes of stroke patients with acute large vessel occlusion in the anterior circulation after endovascular treatment (EVT). METHODS: We retrospectively analyzed the baseline, laboratory, surgical and 90-day follow-up data of patients with stroke resulting from acute large vessel occlusion in the anterior circulation, who underwent emergency endovascular treatment in our hospital from July, 2015 to December, 2020. A favorable outcome was defined as a modified Rankin scale score ≤2 at 90 days. Univariate and multivariate regression analyses were performed to explore the relationship between nutritional status and 90-day functional outcomes of the patients. RESULTS: A total of 459 patients (mean age of 68.29±11.21 years, including 260 males) were enrolled in this study. According to their prognostic nutritional index (PNI), the patients were divided into normal nutrition group (392 cases, 85.4%), moderate malnutrition group (44 cases, 9.6%), and severe malnutrition group (23 cases, 5.0%). Univariate analysis showed that the patients with good clinical outcomes had a lower proportion of malnutrition with a younger age, a lower rate of diabetes, lower baseline blood pressure, lower baseline NIHSS score, higher baseline ASPECT score, and higher rates of good collateral circulation and complete vascular recanalization. Multivariate analysis showed that in addition to age, diabetes, baseline systolic blood pressure, successful recanalization, baseline ASPECT score, baseline NIHSS score and collateral circulation, a greater PNI was a protective factor for a good 90-day outcome of patients after EVT (moderate vs severe: OR=0.245, 95% CI: 0.066-0.908, P=0.035; normal vs severe: OR=0.185, 95% CI: 0.059-0.581, P=0.004). CONCLUSION Nutritional status an important factor affecting the 90-day outcomes after EVT of stroke patients with acute large vessel occlusion in the anterior circulation.

Objective: Nutrition is closely related to the health of the elderly population. This study aimed to provide a comprehensive picture of the nutrition status of elderly Chinese and its related dietary, geographical, and socioeconomic factors. Methods: A total of 13,987 ≥ 60-year-old persons from the 2010-2013 Chinese National Nutrition and Health Survey were included to evaluate various aspects of malnutrition, including underweight, overweight or obesity, and micronutrient inadequacy. Results: Overall, the prevalence of obesity, overweight, and underweight was 12.4%, 34.8%, and 5.7%, respectively, with disparities both geographically and socioeconomically. The prevalence of underweight was higher among the older old (≥ 75 years), rural residents and those with low income, with low education status, and residing in undeveloped West areas. More than 75% of the elderly do not meet the Dietary Reference Intakes for vitamins A, B Conclusions Obesity epidemic, inadequacy of micronutrient intake, and high prevalence of underweight and anemia in susceptible older people are the major nutrition challenges for the rapidly aging population in China.

OBJECTIVE: To systematically evaluate the association of early nutrition intake with the risk of bronchopulmonary dysplasia (BPD). METHODS: PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, and Weipu Periodical Database were searched for the observational studies on the association between early nutrition intake and BPD. RevMan 5.3 software was used to perform a Meta analysis of eligible studies. RESULTS: Eight observational studies were included, with 548 infants with BPD and 522 infants without BPD. The Meta analysis showed that the BPD group had a significantly lower caloric intake than the non-BPD group within the first week after birth and in the first 2 weeks after birth ( CONCLUSIONS Early nutrition deficiency may be associated with the development of BPD, and more attention should be paid to enteral feeding of infants at a high risk of BPD to achieve total enteral feeding as soon as possible.

OBJECTIVE: To investigate the relationship between malnutrition-inflammation-atherosclerosis (MIA) syndrome and deterioration of global and specific domains of cognitive function in peritoneal dialysis (PD) patients. METHODS: This was a multi-center prospective cohort study. The PD patients who met the inclusion criteria were examined with general and specific cognitive function between March 2013 and November 2013. The patients were divided into MIA0, MIA1 and MIA2 groups, according to items of "Yes" for whether or not having cardiovascular disease, serum albumin≤35 g/L or high-sensitive C-reactive protein (hs-CRP) ≥3 mg/L. After 2 years, the patients maintained on PD would be repeatedly measured with cognitive function. The Chi-square test, One-way ANOVA, Kruskal-wallis H rank sum test were used to compare the differences of clinical characteristics, biochemical data, and global and specific cognitive function parameters among the three groups at baseline, and two years later, respectively. The Bonferroni method was applied to adjust the significance level for further comparison between each two different groups. The change of score in each cognitive parameter of global and specific domains was used as dependent variable. Age, gender, education level, depression index, body-mass index, diabetes mellitus, serum sodium levels and MIA (MIA0 was control, MIA1 and MIA2 as dummy variables) were all included in the multivariable linear regression models to analyze the risk factors of the deterioration of cognitive function. The analysis for each cognitive domain was adjusted for the baseline score of the corresponding cognitive parameter. All the analyses were performed using SPSS for Windows, software version 25.0 (SPSS Inc., Chicago, IL). RESULTS: Over two-year follow up, the prevalence of cognitive impairment increased from 20.0% to 24.7%, absolute decrease of 3MS scores were more significantly decreased in MIA2 (-3.9±12.0 vs. 1.1±6.7, P<0.01) and MIA1 group (-2.3±11.8 vs. 1.1±6.7, P<0.05) than those in MIA0 group respectively. Specific cognitive functions, included executive function (trail-making tests A and B, P=0.401, P=0.176), immediate memory (P=0.437), delayed memory (P=0.104), visuospatial skill (P=0.496), and language ability (P=0.171) remained unchanged. Advanced age, lower education, diabetes mellitus and depression were all correlated with the deterioration of one or more cognitive domains, and the patients having one item of MIA syndrome were prone to develop the deterioration of 3MS (P=0.022). Furthermore, the patients having two or more items of MIA syndrome were more likely to develop the deterioration of not only 3MS (P <0.001), but also delayed memory, visuospatial skill, and language ability (P=0.002, P=0.007, P=0.004, respectively). CONCLUSION Patients with one item or above of MIA syndrome were at high-risk for the deterioration of global cognitive function. The more MIA syndrome items there were, the more specific cognitive domains deteriorated.

OBJECTIVEUndernutrition is highly prevalent among older people. The aim of this study was to estimate the prevalence of undernutrition in elderly Chinese residents and explore the relationship between undernutrition and dietary factors.

METHODSData were collected from 2,552 elderly people aged 75 years and over from the Chinese Nutrition and Health Surveillance during 2010-2012 using questionnaires, anthropometric measurement, and individual consecutive 3-day 24-hour dietary records.

RESULTSThe present study showed that 10.5% of participants had undernutrition. The prevalence was higher among the population living in rural areas, those living in the South region, those who smoked, and those with low income levels. Most participants failed to meet the Chinese Dietary Reference Intakes for energy (66.1%) and protein (72.1%). When comparing quartiles of food intake, high rice consumption [odds ratio (OR) = 2.44, 95% confidence interval (CI): 1.35-4.40)], animal oil intake (OR = 1.60, 95% CI: 1.18-2.17), and high fat intake from animal sources (OR = 1.56, 95% CI: 1.06-2.31) were positively associated with underweight whereas high wheat consumption (OR = 0.44, 95% CI: 0.26-0.74), a proper proportion (24%-32%) of energy intake from fat (OR = 0.54, 95% CI: 0.35-0.83), and high fat intake from plant sources (OR = 0.67, 95% CI: 0.46-0.99) were inversely related.

CONCLUSIONThe prevalence of undernutrition was high among elderly Chinese people, especially in rural areas. Dietary factors, such as high consumption of rice, were associated with undernutrition.

OBJECTIVETo investigate the nutritional risk in children with severe pneumonia using the Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP) and the association between nutritional risk and adverse clinical outcomes.

METHODSAccording to the STAMP score, 216 children with severe pneumonia were classified into high nutritional risk group (HR group; n=98), moderate nutritional risk group (MR group; n=65), and low nutritional risk group (LR group; n=53). Fasting blood samples were collected to measure the levels of insulin-like growth factor-1 (IGF-1), adiponectin, leptin, non-esterified fatty acid (NEFA), albumin, transferrin, prealbumin, and retinol binding protein (RBP). The adverse clinical outcomes were recorded.

RESULTSCompared with the MR and LR groups, the HR group had significantly lower serum levels of IGF-1, leptin, adiponectin, prealbumin, and RBP, as well as a significantly higher serum level of NEFA (P<0.05). Compared with the MR and LR groups, the HR group had a significantly higher proportion of children admitted to the intensive care unit and a significantly longer duration of mechanical ventilation (P<0.05). The HR group had a significantly longer mean hospital stay and a significantly higher incidence rate of complications compared with the LR and MR groups (P<0.05).

CONCLUSIONSNutritional risk screening has an important value in evaluating the clinical outcome of children with severe pneumonia, and children at a higher nutritional risk tend to have more adverse clinical outcomes.
