Chronic kidney disease and cognitive performance: NHANES 2011-2014.

PURPOSE: Previous studies suggest an association between chronic kidney disease (CKD) and cognitive impairment. The purpose of this study was to explore the association between the diverse stages of CKD and the cognitive performance of elderly American adults. METHODS: Data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 were used. Multivariate adjusted logistic regression, subgroup analysis, and the restricted cubic spline model were used to assess the associations of CKD stage and estimated glomerular filtration rate (eGFR) with cognitive performance. The measures used to evaluate cognitive function included the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) test, the Animal Fluency test, and the Digit Symbol Substitution test (DSST). RESULTS: This study included 2234 participants aged ≥ 60 years. According to the fully adjusted model, stages 3-5 CKD were significantly associated with the CERAD test score (OR = 0.70, 95% CI [0.51, 0.97], p = 0.033), the Animal Fluency test score (OR = 0.64, 95% CI [0.48, 0.85], p = 0.005), and the DSST score (OR = 0.60, 95% CI [0.41, 0.88], p = 0.013). In addition, the incidence of poor cognitive function increased with decreasing eGFR, especially for individuals with low and moderate eGFRs. Both the DSST score (p nonlinearity < 0.0001) and the Animal Fluency test score (p nonlinearity = 0.0001) had nonlinear dose-response relationships with the eGFR. However, a linear relationship was shown between the eGFR and CERAD test score (p nonlinearity = 0.073). CONCLUSIONS: CKD, especially stages3-5 CKD, was significantly associated with poor cognitive performance in terms of executive function, learning, processing speed, concentration, and working memory ability. All adults with CKD should be screened for cognitive impairment.

The Effect of Enhanced Recovery After Surgery Nursing on the Recovery in Patients After Liver Transplantation.

OBJECTIVE: To explore the effect of enhanced recovery after surgery nursing on the recovery in patients after liver transplantation. METHODS: This study was performed in 128 patients underwent liver transplantation in our hospital. According to the random number table, these patients were divided into the control group (n = 64) and the experimental group (n = 64). Patients in the control group received traditional nursing, while those in the experimental group received enhanced recovery after surgery nursing. Completion time of the operation, the amount of infused red blood cells during operation, intraoperative anhepatic period, intensive care unit (ICU) stay, the total length of hospitalization, the number of patients reintubated after surgery, the survival rate within 1 year after surgery, and the incidence of postoperative complications were compared between the two groups. RESULTS: Intraoperative anhepatic period and the amount of infused red blood cells during operation in the experimental group were lower than those in the control group (both P < .05). Postoperative ICU stay, the total length of hospitalization, and the number of patients reintubated after surgery in the experimental group were decreased when compared with the control group, while postoperative ventilator weaning time was increased (all P < .05). The survival rates at 3 months, 6 months, and 1 year after surgery in the experimental group were higher than those in the control group (all P < .05). Compared with the control group, the total incidence of complications in the experimental group was reduced (P < .05). CONCLUSION: The application of enhanced recovery after surgery nursing in liver transplantation patients contributes to the accelerated recovery of body function, shortened total length of hospitalization and ICU stay, declined complications, and increased survival rate within 1 year.

Carotid Baroreceptor Stimulation Improves Pulmonary Arterial Remodeling and Right Ventricular Dysfunction in Pulmonary Arterial Hypertension.

Autonomic nervous system imbalance is intricately associated with the severity and prognosis of pulmonary arterial hypertension (PAH). Carotid baroreceptor stimulation (CBS) is a nonpharmaceutical intervention for autonomic neuromodulation. The effects of CBS on monocrotaline-induced PAH were investigated in this study, and its underlying mechanisms were elucidated. The results indicated that CBS improved pulmonary hemodynamic status and alleviated right ventricular dysfunction, improving pulmonary arterial remodeling and right ventricular remodeling, thus enhancing the survival rate of monocrotaline-induced PAH rats. The beneficial effects of CBS treatment on PAH might be mediated through the inhibition of sympathetic overactivation and inflammatory immune signaling pathways.
