SUV measured in patients with esophageal cancer, reflecting the metabolic activity of tumor and malignancy, could serve as a prognostic factor. Considering that the FDG-PET can add important information of metabolism in detection and staging to conventional imaging modality, we anticipate that SUV could be used in patients with esophageal carcinoma.

Objective Subjects with mild cognitive impairment (MCI) may revert to normal cognition (NC), but predictive factors are under study. We therefore sought to identify factors which could help in predicting reversion from MCI to NC. Methods Relevant studies were retrieved from PubMed, EMBASE, Cochrane Library, MEDLINE, Web of Science, EBSCO, and OVID. According to the inclusion and exclusion criteria, high‐quality assessments of relevant literatures were conducted, followed by data extraction and meta‐analysis with Stata 12.0 software. Results A total of 17 studies with 6829 participants were included in the meta‐analysis. The overall reversion rate is 27.57%. Positive predictive factors were found in younger age (SMD = −0.345, 95% CI, −0.501 to −0.189), higher education level (SMD = 0.337, 95% CI, 0.117‐0.558), no APOE ε4 allele (OR = 0.728, 95% CI, 0.575‐0.922), no hypertension (OR = 0.826, 95% CI, 0.692‐0.987), no stroke (OR = 0.696, 95% CI, 0.507‐0.953), and higher Mini‐Mental State Examination (MMSE) score (SMD = 0.707, 95% CI, 0.461‐0.953). Conclusion Individuals who are at young age, have higher education level and MMSE score, and have no APOEe4 allele, no hypertension, and no stroke had a high probability to revert from MCI to NC.

Objectives –  The safety and efficacy of early acetylcholinesterase inhibitors therapy in patients with cognitive impairment no dementia (CIND) after a cerebrovascular accident have not been examined. In this study, we investigated the safety and efficacy of rivastigmine in cognition, particularly executive function in patients with CIND because of cerebrovascular disease. Methods –  This study was a 24‐week, double‐blind, randomized, placebo‐controlled trial of ischemic stroke patients seen at a tertiary hospital who had cognitive impairment no dementia because of cerebrovascular disease. The intervention was either rivastigmine or placebo up to 9 mg/day. The primary outcome of interest was mean change from baseline in the Ten‐Point Clock Drawing and Color Trails 1 and 2. Results –  Fifty patients were randomized into rivastigmine (n = 25) and placebo (n = 25) arms. Patients in the rivastigmine group showed statistically significant improvement (1.70 vs 0.13, P = 0.02) on the animal subtask of the verbal fluency measure compared with placebo. There was also a trend (non‐significant) towards improvement in Color Trails II. Conclusions –  In this pilot study, we demonstrated that rivastigmine was well tolerated in patients with CIND because of cerebrovascular disease and may potentially improve executive functioning.

The neutrophil-to-lymphocyte ratio (NLR) and red blood cell distribution width (RDW) are important indicators of adverse outcomes and have predictive value for many diseases; however, the relationships between frailty, and the NLR and RDW in patients with coronary heart disease (CHD) have not been determined. In this cross-sectional study, we investigated the association between frailty, and the NLR and RDW in elderly CHD patients ≥ 60 years of age. Frailty was defined according to frailty phenotype. Of 345 patients enrolled in the study, 22.6%, 58.3%, and 19.1% were characterized as robust, pre-frail, and frail, respectively. A significant positive correlation was observed between frailty and the NLR (r = 0.169) and RDW (r = 0.196). After adjusting for confounders, linear regression analyses showed that participants in the 4th quartile of the NLR or RDW were more likely to have a higher frailty phenotype score. Based on multivariable logistic regression, patients in the 4th quartile of the NLR and RDW, the fully-adjusted odds ratios for incident frailty were 2.894 (p = 0.011) and 2.494 (p = 0.040), respectively. Our findings indicate that frailty is associated with the NLR and RDW in elderly patients with CHD.

The purpose of this study was to explore the relationship between social support, health literacy, and health care utilization in older Chinese adults. A cross-sectional survey design was employed. Data were collected from 32 nursing homes from Urumqi in Xinjiang of China. A total of 1486 respondents completed a pack of questionnaires. The average health literacy level of older adults in nursing homes was relatively low, only 73.68 ± 29.42 points; the average social support level was also relatively low, only 31.42 ± 7.12 points (lower than domestic norm of Chinese residents, P < .001). Both values were below the midpoint for the overall population, indicating a sample with below-average levels of healthy literacy and social support. Low social support levels are associated with poor health literacy and greater likelihood of hospital admission ( P < .05). Social support was significantly associated with health literacy. Improving the quantity and quality of social support may be an effective means to obtain better health literacy and lower hospital admissions.

BackgroundMild cognitive impairment (MCI) represents a transitional stage between normal aging and dementia. Uric acid is a water-soluble antioxidant found in the body. Many recent studies have found that uric acid plays an important role in cognitive impairment, although the effects of uric acid on MCI are not clear.ObjectiveThe objective of this study was to explore the relationship between uric acid and MCI.MethodsUsing a random sampling method, this study investigated 58 patients with MCI and 57 healthy elderly from January 2016 to November 2016. Demographic information was collected, the subjects were evaluated using the Mini Mental Status Examination (MMSE), and uric acid was measured in fasting venous blood.ResultsA total of 57 (49.6%) participants are healthy and 58 (50.4%) participants had MCI. The uric acid level was significantly lower in the patients with MCI (292.28±63.71 μmol/L) than in the normal controls (322.49±78.70 μmol/L; P<0.05). There were significant positive correlations between the MMSE scores, for each dimension and the total score, and uric acid level (all P<0.05). Multivariate logistic regression models illustrated that uric acid was a protective factor for MCI (odds ratio =0.999, 95% CI =0.987–0.999).ConclusionA low uric acid level is a risk factor for MCI, and an appropriate increase in uric acid can be used to slow down the occurrence and development of MCI.

It is very important to estimate the prevalence of inadequate health literacy and determine whether or not health literacy level differences predict the physical and mental health status of older adults. A cluster sampling method was selected. A total of 1396 older adults were interviewed. Three instruments were included: the Chinese Citizen Health Literacy Questionnaire, Short Form 36, and Activity of Daily Living (ADL) Scale. The health literacy scores were very low (71.74 ± 28.35). The physical and mental health scores were all moderate. The ADLs was ⩾22, which suggests that the ADLs of older adults were poor. The major influencing factors of physical health include health literacy, ADL, alcohol consumption, household income, marital status, and former occupation. The major factors influencing mental health included ADL, former occupation, age, and smoking. Health literacy was associated with physical health, but was not associated with mental health. Improving health literacy could increase health management and health status of older adults.
