ObjectiveTo explore the causes of colon-anal anastomotic stenosis in patients with low rectal cancer after prophylactic ileostomy under complete laparoscopy. MethodsA total of 194 patients with low rectal cancer who received complete laparoscopic radical resection of rectal cancer combined with preventive ileostomy in our hospital from January 2020 to December 2020 were selected as the study objects, and were divided into non-stenosis group (n=136) and stenosis group (n=58) according to postoperative colon-anal anastomosis stenosis. The clinical data of the two groups were compared. Univariate and multivariate logistic regression were used to analyze the factors affecting postoperative colon-anal anastomotic stenosis, and stepwise regression was used to evaluate the importance of each factor. The risk prediction model of postoperative colon-anal anastomotic stenosis was constructed and evaluated. ResultsIn the stenosis group, the proportion of males, tumor diameter ＞3 cm, NRS2002 score >3 points, manual anastomosis, left colic artery not preserved, anastomotic leakage, pelvic infection and patients undergoing neoadjuvant radiotherapy and neoadjuvant chemotherapy were higher than those in the non-stenosis group (P<0.05). The results of univariate logistic analysis showed that female and preserving the left colonic artery were the protective factors for postoperative colon-anal anastomotic stenosis (P<0.05), and the tumor diameter >3 cm, NRS2002 score >3 points, manual anastomosis, anastomotic leakage, pelvic infection, neoadjuvant radiotherapy and neoadjuvant chemotherapy were the risk factors for postoperative colon-anal anastomotic stenosis (P<0.05). Multivariate logistic regression analysis showed that gender, tumor diameter, NRS 2002 score, anastomotic mode, anastomotic leakage, and pelvic infection were independent influencing factors for postoperative colon-anal anastomotic stenosis (P<0.05). Stepwise regression analysis showed that the top three factors affecting postoperative colon-anal anastomotic stenosis were NRS 2002 score, gender and anastomotic leakage. Multivariate Cox risk proportional model analysis showed that the multivariate model composed of NRS 2002 score, gender and anastomotic leakage had a good consistency in the risk assessment of postoperative colon-anal anastomotic stenosis. Based on this, a risk prediction model for postoperative colon-anal anastomotic stenosis was constructed. The results of strong influence point analysis show that there are no data points in the modeling data that have a strong influence on the model parameter estimation (Cook distance <1). Receiver operating characteristic curve results showed that the model had good differentiation ability, the area under curve was 0.917, 95%CI was (0.891, 0.942). The calibration curve was approximately a diagonal line, showing that the model has good predictive power (Brier value was 0.097). The results of the clinical decision curve showed that better clinical benefits can be obtained by using the predictive model to identify the corresponding risk population and implement clinical intervention. ConclusionThe prediction model based on NRS 2002 score, gender and anastomotic fistula can effectively evaluate the risk of colon-anal anastomotic stenosis after preventive ileostomy in patients with low rectal cancer under complete laparoscopy.
Objective To assess the effectiveness of psychological intervention on post-stoke depression. Methods Such databases as the JBI Database of Systematic Review (1980 to June, 2010), The Cochrane Library (1980 to June, 2010), PubMed (1966 to 2010), CINAHL(1982 to May, 2000), CBM (1978 to 2010), and CNKI (1979 to 2010) were searched to collect randomized controlled trials (RCTs). In accordance with the predefined inclusion and exclusion criteria, the quality of included studies was evaluated, and then meta-analyses were performed by using RevMan 5.0 software. Results A total of 33 RCTs were included. The results of meta-analyses showed: (1) Compared with the control group, the short-term effect of psychological intervention was more effective in decreasing depression score. The subgroup analysis showed that the intervention effects at the time of four weeks, six weeks, eight weeks, and 12 weeks were better than those of the control group. (2) The long-term effect of psychological intervention was more effective in decreasing depression score. The subgroup analyses showed that the intervention effects at the interval of eight weeks, 24 weeks, and 48 weeks were better than those of the control group. (3) The combined or single application of either cognitive-behavioral psychotherapy or supportive psychotherapy was more effective in decreasing depression score than the control group. However, there was no significant difference between the general psychological treatment group and the control group. (4) The subgroup analyses showed that the different qualities of the included studies were more effective than those of the control group. Conclusion Various psychological intervention is effective in decreasing the patient’s depression score, and cognitive-behavioral therapy and supportive psychotherapy, especially, can significantly improve the depression state and promote recovery.
Objective To evaluate the effect of a health education for preventing HIV/AIDS in floating population. Methods A computerized literature search was carried out in PubMed, CBM (Chinese Biomedical Database), CNKI (Chinese National Knowledge Infrastructure), Wanfang (Chinese) and VIP (Chinese) databases to collect articles published between 1996 and 2006 concerning the effect of a HIV/AIDS education intervention in floating population. We also checked the reference lists of relevant articles. The study type was self-control intervention study. Meta-analyses were performed to assess 3 outcomes of the intervention, i.e. knowledge about HIV transmission, means of prevention and attitudes towards HIV/AIDS patients. Fixed and random effect models were employed to combine results after a heterogeneity test, with rate difference (RD) used as the indicator of intervention effect. Results The analysis showed that the RD for knowing the sexual transmission route of HIV, the RD for knowing the effect of condoms for HIV prevention, and the RD for changing attitudes towards HIV/AIDS patients, i.e. treating them as ordinary people, were increased by 16% (0.10, 0.22), 22% (0.17, 0.28) and 19% (0.13, 0.25), respectively. Conclusion Health education for preventing HIV/AIDS is effective in changing knowledge and attitudes in floating population.
