ABSTRACT
Objective:To develop a Beijing norm of Memory and Executive Screening (MES) scale to facilitate its further promotion and application in the future.Methods:Study subjects were selected based on the inclusion and exclusion criteria, including patients who visited the memory clinic of Xuanwu Hospital of Capital Medical University from March 20, 2017 to January 6, 2021, and normal people recruited simultaneously from community, and trained and qualified investigators conducted questionnaire surveys through face-to-face interviews. Then strict quality control, data collection and statistical analysis were performed.Results:A total of 607 participants were included, including 239 normal people, 293 individuals with subjective cognitive decline (SCD), and 75 individuals with mild cognitive impairment (MCI). There was a negative correlation between the scores of MES and age ( r=-0.19, P<0.001), but a positive correlation between scores of MES and education level ( r=0.29, P<0.001). The optimal cut-off value of this scale in Beijing was 86 points, the area under curve (AUC) of the cut-off value to distinguish MCI was 0.847 (normal people vs MCI) and 0.826 (SCD vs MCI), and after adding demographic variables, AUC showed slight increase (0.847 to 0.850 and 0.826 to 0.847), whereas the differences were not statistically significant ( Znormal peoplevsMCI=0.49, ZSCDvsMCI=1.21, P>0.05). And there was no statistically significant difference between MES and Montreal Cognitive Assessment scales in diagnostic power for normal people and people with MCI ( Zscale alone=1.03, Zafter adding demographic variables=1.13, P>0.05). Conclusions:The MES scale has a better distinguishing power for MCI, and its optimal cut-off value in Beijing is 86 points, which is different from previous studies. In the future, the sample size needs to be further expanded to verify this norm.
ABSTRACT
Sarcopenia is becoming one of the challenges that is associated with worse quality of life and death.Accurate evaluation of skeletal muscle quantity and quality is the most important for the screening and diagnosing sarcopenia.Compared with other imaging evaluation methods, ultrasound examination is a portable, no-ionizing radiation and inexpensive technique, and especially has a high repeatability.After a comprehensive overview of the imaging tests assessing skeletal muscle, this review summarized ultrasound examination requirements for assessing skeletal muscle, measurement parameters, and future perspectives.
ABSTRACT
Objective:To explore the relationship between atrial fibrillation stroke risk score (CHA2DS2-VASc score) and short-term prognosis of aged patients with nonvalvular atrial fibrillation (NVAF)complicated ischemic cerebral stroke (ICS).Methods:A total of 206 aged NVAF+ ICS patients who hospitalized in our hosipital from Jun 2011 to Aug 2013 were selected.CHA2DS2-VASc score was used to perform stroke risk stratification,and patients were di- vided into low risk group (n=24,0 score),medium risk group (n=78,1 score)and high risk group (n=104,2~9 scores).Modified Rankin scale (mRS)was used to assess patients'prognosis on three months after onset.According to mRS score,patients were divided into good prognosis group (n=89,0~2 scores)and poor prognosis group (n=117,3~6 scores).Independent predictors for poor prognosis in three months were analyzed.Results:Compared with low risk group,there were significant rise in age,percentages of hypertension,diabetes mellitus (DM),heart failure,stroke and vascular disease history,scores of United States national institutes of health stroke score (NIHSS) in medium and high risk groups (P<0.05 or <0.01).Compared with good prognosis group,there were significant rise in age [(72.81±7.68)years vs.(81.56±8.03)years],percentages of hypertension (58.4% vs.71.8%)and stroke history (9.0% vs.29.9%),scores of NIHSS [(2.97±1.42)scores vs.(7.67±3.92)scores]and CHA2DS2- VASc [(1.70±1.63)scores vs.(4.03±2.53)scores]in poor prognosis group,P<0.05 or <0.01. Multi-factor Logistic regression analysis indicated NIHSS score (high risk:OR=1.78,95%CI:1.27~2.56,P=0.001 ), CHA2DS2-VASc scores (high risk:OR=3.24,95%CI:1.32~6.98,P=0.001)and age (high risk:OR=1.23, 95%CI:1.07~1.54,P=0.01)were independent predictors for poor prognosis on three months in aged NVAF +ICS patients.Conclusion:CHA2DS2-VASc score is related to early improvement of patients with NVAF + ICS;age,scores of NIHSS and CHA2DS2-VASc are independent predictors for poor short-term prognosis.
