The mean LOS was 21.4 ± 17.7 days. Both classification systems were correlated with LOS, yet CCI was stronger(Spearman’s ρ: 0.694 vs 0.602, P < 0.001). Female patients (P = 0.019) and patients with pre-transplant cardiovascularevents (P = 0.02) had longer LOS. After adjusted multivariable analysis, the link between LOS and both theCDC and CCI remained relevant. CCI had a superior fit compared to CDC (r2 = 0.729 vs r2 = 0.481), with every 10CCI points being associated with a 5.27 day (P < 0.001) increased LOS.CONCLUSIONThis study showed that the CCI was better linked with LOS compared to CDC and might represent a useful scoreto evaluate the overall burden of postoperative complications in patients undergoing SPK.展开更多

文摘BACKGROUND Chronic pain and depression often coexist,severely affecting quality of life.Traditional treatments address these conditions separately,but comprehensive psychological cognitive nursing offers a holistic approach.By combining cognitive-behavioral strategies and psychological support,it helps improve coping mechanisms,reduce distress,and enhance overall well-being in affected patients.AIM To investigate the impact of comprehensive psychological cognitive nursing on the patients with chronic pain and depression.METHODS From October 2022 to October 2024,171 patients with chronic pain and depression admitted to our hospital were randomly divided into two groups,with 85 patients in the control group and 86 patients in the observation group.The general data from both groups were compared.The control group received standard treatment.The observation group provided full psychological cognitive care in the same way as the control group did.The two groups of patients'psychological states,pain levels,quality of life,sleep quality,and nurse satisfaction were compared before to and during the intervention.RESULTS Compared with the control group,the self-rating anxiety scale(SAS)score,selfrating depression scale(SDS)score,visual analog scale(VAS)score,and Pittsburgh Sleep Quality Index(PSQI)score of the observation group significantly decreased after intervention,while the short-form 36(SF-36)score significantly increased(P<0.05).The SAS score decreased by 17.36%;SDS score decreased by 26.21%.The VAS scores decreased by 57.14%,63.43%,and 69.86%at 12 hours,24 hours and 48 hours,respectively.The SF-36 score indicators increased by 13.29%,13.24%,20.77%,and 19.41%,respectively;The PSQI score decreased by 54.66%.The observation group reported higher nurse satisfaction.CONCLUSION Comprehensive psychological cognitive nursing interventions can significantly reduce patients'pain and depression symptoms while boosting their confidence in managing the illness.
文摘BACKGROUND Detailed data on the relation of post-operative complications with clinical outcomes after simultaneous pancreas-kidney(SPK)transplantation is lacking.AIM To compare Clavien-Dindo classification(CDC)and comprehensive complication index(CCI)in predicting outcomes after SPK.METHODS Data for patients undergoing SPK between 1999-2019 were analyzed.Information on recipients’baseline characteristics,peri-operative management and postoperative complications were collated.Length of hospital stay(LOS)was the primary study outcome,and the associations with CDC and CCI were evaluated using Spearman’s(ρ)correlation coefficients.RESULTS In the study period,data were available for 128 patients(female n=44,34.4%).Sixty-nine patients had at least one complication with the highest CDC grade of I,II,III,and IV in 8(6.3%),22(17.2%),32(25%),and 7(5.5%)patients,respectively. The mean LOS was 21.4 ± 17.7 days. Both classification systems were correlated with LOS, yet CCI was stronger(Spearman’s ρ: 0.694 vs 0.602, P < 0.001). Female patients (P = 0.019) and patients with pre-transplant cardiovascularevents (P = 0.02) had longer LOS. After adjusted multivariable analysis, the link between LOS and both theCDC and CCI remained relevant. CCI had a superior fit compared to CDC (r2 = 0.729 vs r2 = 0.481), with every 10CCI points being associated with a 5.27 day (P < 0.001) increased LOS.CONCLUSIONThis study showed that the CCI was better linked with LOS compared to CDC and might represent a useful scoreto evaluate the overall burden of postoperative complications in patients undergoing SPK.

文摘The application of ecosystem services(ES)theories in land consolidation is a confusing issue that has long plagued scholars and government officials.As the upgraded version of traditional land consolidation,comprehensive land consolidation(CLC)emphasizes ecological benefits,but it does not achieve the expected effect during the pilot phase.This study first proposed a theoretical analysis framework based on ES knowledge to answer the three key questions of why,where,and how to implement CLC better.Taking mountainous counties as the study area,we found that ES trade-offs/synergies,bundles,and drivers were significantly affected by scale effects.ES knowledge can play a crucial role in designing multi-scale CLC strategies regarding the objective,zoning,intensity,and mode.Specifically,mitigating the significant trade-offs between recreational opportunities,food production,and other ES is the top priority of CLC.Land consolidation zoning based on the ES bundles analysis is more rational and can provide the scientific premise for designing locally adapted CLC measures.Land consolidation can be classified into high-intensity direct intervention and low-intensity indirect intervention modes,based on the major drivers of ES.These findings help narrow the gap between ES and CLC practices.
