Validation of the revised mini nutritional assessment short-forms in geriatric internal medicine patients / 肠外与肠内营养

Objective:To validate the revised BMI-MNA-SF and CC-MNA-SF with regard to association and agreement with the full MNA(R),considered as gold standard,in geriatric internal medicine patients.Methods:105 cases of hospitalized elderly patients in internal medicine were recruited for the study.The nutritional status correlation and coherence were evaluated with the revised BMI-MNA-SF、CC-MNA-SF and the full MNA(R),respectively.Results:The BMI-MNA-SF and CC-MNA-SF all correlated strongly with the full MNA(R) (Pearson's correlation coefficient r=0.9080,0.8381 respectively;P ＜ 0.001).High values of sensitivity,specificity and predictive values were observed for the BMI-MNA-SF and CC-MNA-SF against the full MNA(R) as the dichotomized categorizations "malnourished-at risk of malnutrition" vs "well nourished" and "malnourished" vs "at risk of malnutrition-well nourished" were considered.Most of values of those for CC-MNA-SF are lower slightly than BMI-MNA-SF.Areas under the ROC curves also reached high values (BMI-MNA-SF:0.951 and CC-MNA-SF:0.938 for the first categorization;BMI-MNA-SF:1.000 and CC-MNA-SF:0.985 for the second one) showing both tests excellent accuracy with the full-MNA.The agreement between the MNA-SFs and the ful1-MNA was quantified as the percentage of correct classifications.The BMI-MNA-SF classified 83.81％,correctly and the CC-MNA-SF classified 68.57％ correctly.Malnutrition proportions of subjects were not underestimated by both MNA-SFs.Conclusion:The revised BMI-MNA-SF and CC-MNA-SF are rapid、easy and reliable tools are capable to identify malnourished individuals in internal medicine and those who are at risk of malnutrition.Due to the special characteristics of elderly patients,the CC-MNA-SF is a good option to replace the BMI-MNA-SF when BMI is not available.

Scrotal calculi: advances in clinical research / 中华男科学杂志

Scrotal calculi are freely mobile calcified bodies or stones located between the layers of the tunica vaginalis of the testis. The literature on this relatively rare benign lesion consists mostly of case reports. In most cases, scrotal calculi are found incidentally during ultrasound examination. Now with the application of high-frequency ultrasonography, the detection rate of scrotal calculi is gradually increasing. This article summarizes the etiology, pathogenesis, clinical manifestations, diagnosis, and treatment of scrotal calculi.
