OBJECTIVETo evaluate the value of Mini Nutritional Assessment (MNA) in geratic patients with chronic obstructive pulmonary disease (COPD) and analyze the correlation of MNA scores with BODE indexes.

METHODSA total of 139 geratic outpatients with stable COPD admitted from April 2012 to October 2012 were enrolled. The nutritional statuses of the patients were assessed using MNA and the patients were subsequently classified into well-nourished group, risk of malnutrition group and malnutrition group. For all the patients, the anthropometric parameters, pulmonary function and 6-minute-walk distance (6MWD) were examined, and functional dyspnea was evaluated using Modified Medical Research Council Scale (MMRC). The BODE indexes were calculated and analyzed for their correlation with the MNA scores.

RESULTSThe 3 groups showed no significant differences in gender distribution (P>0.05), but their age, anthropometric parameters and BODE indexes (BMI, MMRC, 6MWD, FEV1%pred) differed significantly (P<0.001). In all the patients, MNA scores showed a significant inverse correlation with BODE index (r=-0.602; P<0.001).

CONCLUSIONMNA scores are strongly correlated with the anthropometrical parameters and BODE indexes to allow screening of the nutritional status in patients with COPD. Nutrition is an important factor affecting the disease symptoms, and nutritional improvement is one of the effective measures to relieve the symptoms of COPD.

Objective:To explore the changes in early postpartum pelvic floor muscle strength following the implementation of the new labor process.Methods:This retrospective cohort study selected 1 834 primiparous women with singleton, full-term pregnancies who delivered at Peking University First Hospital from February 2011 to March 2016 and had a pelvic floor re-examination 6-8 weeks postpartum. Out of these, 738 cases who followed the old labor process before 2014 were categorized as the old process group, and 1 096 cases who followed the new labor process after 2014 were categorized as the new process group. Basic data, childbirth information, and postpartum pelvic floor muscle strength of the two groups were compared. Data were statistically analyzed using t-test, Chi-square test, Mann-Whitney U test, Wilcoxon rank-sum test, and ordered multicategory logistic regression to assess the impact of the new and old labor process and other factors on pelvic floor muscle strength. Results:The total duration of labor, as well as the duration of the first, second, and third stages of labor, were longer in the new process group than in the old process group [549.0 min (360.0-768.0 min) vs. 482.5 min (328.0-635.0 min), 465.0 min (297.5-672.5 min) vs. 420.0 min (285.0-555.0 min), 42.0 min (24.0-74.0 min) vs. 27.0 min (18.0-45.0 min), with Z-value of－5.72,－3.95, and－9.28, all P<0.05). The rates of vaginal delivery and labor analgesia were higher in the new process group [72.1% (790/1 096) vs. 67.2% (496/738), χ2=7.41; 67.4% (739/1 096) vs. 53.4% (394/738), χ2=36.82; both P<0.05]. There were no statistically significant differences in the comparison of Class Ⅰ and Class Ⅱ muscle strength grades between the two groups (all P>0.05). Conclusion:There was no significant decline in early postpartum pelvic floor muscle strength following the implementation of the new labor process standards.
