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.

[Effect of two-level community-based health education pattern on schistosomiasis control].

OBJECTIVE: To implement a two-level community-based health education pattern of schistosomiasis in residents of endemic areas in marshland and lake regions, so as to explore the suitable pattern of health education under hypo-endemic situation. METHODS: Two schistosomiasis endemic villages in Jiangling County, Hubei Province were collected as study areas, and among which, one village was treated as an intervention group, where the two-level community-based health education pattern as well as regular control measures was implemented; the other village was a control group, where only regular control measures were implemented. The awareness rates on schistosomiasis control, the rates of correct behavior and the compliance rates of examination, treatment and chemotherapy of the two groups before and after the intervention were compared. RESULTS: According to the results of the baseline survey in 2014, the awareness rates of schistosomiasis control of the intervention and control groups were 84.00% and 77.45%, respectively, the correct rates of behavior of the two groups were 72.00% and 63.73%, respectively, and the compliance rates of the treatment were 80.36% and 82.28%, respectively, there were no statistically significant differences between all the above rates of the two groups (all P > 0.05). After the intervention of the two-level community-based health education, the correct rates of behavior, and the compliance rates of examination and chemotherapy of the two groups were 92.31% and 80.37%, 95.11% and 82.55%, 84.13% and 63.64%, respectively, and the differences between all the rates above of the two groups were statistically significant (all P < 0.05). When compared to those before intervention, the growing rates of the compliance rates of examination, treatment and chemotherapy of the intervention group were 20.97%, 15.33% and 23.29%, respectively, while those of control group were 14.27%, 4.17%, -3.77%, respectively, the growing rates of the intervention groups were higher than those of the control groups. CONCLUSIONS: Through the two-level community-based pattern of health education, the compliance rates of examination and treatment of the residents have improved, and therefore, the pattern is suitable for popularization and application in marshland and lake regions.

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.
