Objective We aimed to use 1H-MRS to characterize metabolite concentrations in the bilateral hippo?campus in GPI patient. Methods Metabolite ratios in the bilateral hippocampus were compared between patients with GPI (n=52) and Normal Control (NC) (n=38). Clinical neurological tests were measured in all subjects and were correlat?ed to the metabolite concentrations. Results The GPI patients showed significantly lower concentrations of N-acetylas?partate(NAA)/creatine(Cr) ratios in the bilateral hippocampus region compared to the NC subjects. There was significant?ly difference in the NAA/Cr ratios between the mild GPI dementia and the severe GPI dementia groups on the left hippo?campus region. We found that the NAA/Cr ratios concentrations were positively correlated with Mini Mental state Exami?nation (MMSE) and Montreal Cognitive Assessment scale (MoCA) scores in the left hippocampus region and the mI/Cr ra?tios concentrations were positively correlated. Conclusions GPI Patients have neuronal dysfunction in the bilateral hippo?campus. The severity of cognitive impairments is associated with the severity of the damage in the left side.

Objective To explore the prognostic factors of intensive care unit (ICU) patients. Methods A retrospective cohort study was conducted. The clinical data of patients admitted to ICU of Beijing Geriatric Hospital from January 2005 to December 2016 were collected. According to the prognosis, the patients were divided into death group and survival group, and the mortality trend with time and age was observed. Survival and death were treated as dependent variables, while the gender, age, reason of ICU admission, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, whether undergoing invasive mechanical ventilation (MV), invasive MV reason, duration of invasive MV, whether successful weaning, whether ICU nosocomial infection, hospital acquired pneumonia (HAP), central line-associated bloodstream infection (CLABSI), acute kidney injury (AKI) occurred, whether undergoing continuous blood purification (CBP), whether septic shock occurred, whether undergoing invasive hemodynamic monitoring or blood transfusion and length of ICU stay were used as the independent variables. First, the clinical data was analyzed by univariate analysis. Second, the independent variables influencing the dependent variable were analyzed by logistic regression analysis to screen out prognostic factors of ICU patients. Results During the study period, 1325 patients were treated, 26 patients with missing data, 1299 patients in final group, 865 patients in survival group, and 434 in death group. The proportion of men in the patients was larger (67.7%), and the age span was larger (16-105 years old). The mortality rate in different years showed no significant difference (χ2 = 16.712, P = 0.117), and with the increase of age, the mortality rate of ICU showed an upward trend (χ2 = 16.399, P = 0.022). The univariate analysis showed that ICU deaths were unrelated to gender, but associated with age, APACHE Ⅱ score, invasive MV, invasive MV reason, duration of invasive MV, successful weaning, ICU nosocomial infection, HAP, CLABSI, AKI, septic shock, whether CBP or invasive hemodynamic monitoring, blood transfusion, the reason of ICU admission and the length of ICU stay (all P < 0.05). The relevant factors with statistical difference found in univariate analysis were analyzed in logistic regression analysis, which showed that whether successful weaning [odds ratio (OR) = 0.016, 95% confidence interval (95%CI) = 0.010-0.025], and whether AKI (OR = 3.917, 95%CI = 2.331-6.582) or septic shock occurred (OR = 2.808, 95%CI = 1.604-4.915) were the dependent variables of death or survival (all P = 0.000). Regression coefficient (β value) of successful weaning was -4.155, suggesting that unsuccessful weaning patients were likely to die. The β value of AKI and septic shock was 1.365 and 1.033, suggesting that the patients with AKI or septic shock were more likely to die. Conclusions Whether the success of weaning, whether the occurrence of AKI or septic shock are independent prognostic factors for the prognosis of ICU patients. Measures for the prevention of the above three aspects could improve the prognosis of ICU patients.

Objective To investigate the correlation between serum adiponectin levels and post-stroke cognitive impairment (PSCI). Methods From January 2018 to December 2018, consecutive patients with ischemic stroke admitted to the Departments of Neurology, the Affiliated Brain Hospital of Guangzhou Medical University, Dongguan Changping Hospital, and Jiangsu Provincial Second Chinese Medicine Hospital were enrolled. Serum adiponectin concentration was detected by radioimmunoassay. The cognitive function assessment was performed 1 month after the onset of stroke using the Montreal Cognitive Assessment (MoCA). The total score of MoCA <22 was defined as PSCI. Univariate analysis was used to compare the baseline data between groups, and multivariate logistic regression analysis was used to determine the association between serum adiponectin levels and PSCI. Results A total of 257 patients with acute ischemic stroke were enrolled, with age 66.5 ± 9.9 years, 139 (54.1% ) males, and 91 (35.4% ) with PSCI. Age (68.2 ± 8.1 years vs. 65.6 ± 10.8 years; t=2.007, P=0.046 ), homocysteine (16.0 ± 6.2 μmol/L vs. 14.5 ± 4.5 μmol/L; t= 2.208, P= 0.028 ), and high-sensitivity C-reactive protein ( 7.0 [3.3-9.9] mg/L vs. 4.7 [2.2-9.6] mg/L; Z=2.346, P=0.019 ) as well as the proportion of hypertension (64.8% vs. 50.6% ; χ2 =4.824, P=0.028), diabetes (33.0% vs. 21.1% ; χ2 =4.392, P=0.036), leuko-araiosis (47.2% vs. 32.5% ; χ2 =5.422, P=0.020) and diffusion weighting imaging-Alberta Stroke Project early CT score 0-7 (59.3% vs. 41.4% ; χ2 =6.942, P=0.008) in the PSCI group was significantly higher than that of the non-PSCI group, while the adiponectin level was significantly lower than that of the non-PS-CI group (5.4 [3.5-8.4] mg/L vs. 7.0 [5.3-9.3] mg/L; Z=3.624, P=0.001 ). Multivariate logistic regression analysis showed that after adjusting for the confounding factors, the lower serum adiponectin level was an independent risk factors for PSCI (the 1st quartile group vs. the 4th quartile group: odds ratio 2.152, 95% confidence interval 1.119-5.039; P=0.047). Conclusions Low serum adiponectin level might be an independent risk factor for PSCI in patients with ischemic stroke.
