Objective Pulmonary hypertension (PH) was an independent predictor of mortality and new onset cardiovascular events in maintenance hemodialysis (MHD) patients. Recent studies revealed PH complicated by pericardial effusion (PE) increased mortality in non-CKD (chronic kidney disease) population. No such evidence existed in MHD patients. Methods We enrolled 108 MHD patients with diagnosed PH by echocardiography (61 with PE) between 2009 and 2011. All patients had been followed-up for 2 years. The endpoints were all-cause mor-tality, cardiovascular (CV) mortality and new onset CV events. Results The mean age was (60.2 ± 14.1) years, 55.6% were males and SPAP was (53.0 ± 15.4) mmHg. 12.0% were severe PH and 1.9% were moderate-to-severe PE. The overall mortality, cardiovascular mortality and new on-set cardiovascular events in PE and non-PE group were 34.4% vs. 21.3%、 23.0% vs. 12.8% and 54.1% vs. 42.6%, respectively (P > 0.05). Kaplan-Meier curve showed there was no difference on all-cause mortality , CV mortality nor new-onset CV events between PE and non-PE group (Log Rank P > 0.05). Conclusions Compared with patients without PE, the presence of PE in patients with PH did not increase the mortality and worsen the cardiovascular outcome in MHD patients.

Objective To investigate the related risk factors of contrast-induced acute kidney injury (CI-AKI)after cerebrovascular intervention. Methods The clinical data of 5423 patients performed cerebrovascular angiography and intervention at the Departments of Neurology and Neurosurgery,Guangdong People′s Hospital from January 2005 to December 2013 were analyzed retrospectively. The patients who underwent cerebrovascular angiography and intervention were evaluated and screened. A clinical history database was established. All the selected patients used iodixanol,an isotonic contrast agent. The occurrence of CI-AKI was used as an endpoint. The patients were divided into either a CI-AKI group or a non CI-AKI group. A multivariate Logistic regression model was used to analyze the risk factors associated with the occurrence of CI-AKI. Results A total of 4164 patients were finally enrolled,including 137 had CI-AKI. The incidence of CI-AKI was 3. 3%. The results of multivariate Logistic regression showed that age >60 years (OR,1. 965,95%CI 1. 244-3. 136),baseline estimated glomerular filtration rate (eGFR)<60mL/(min·1. 73 m2)(OR,4. 163,95%CI 2. 422-5. 873),diabetes (OR,3. 140,95%CI 1. 983-3. 902),and anemia (OR,1. 524,95%CI 1. 226 -3. 253)were the influencing factors for occurring CI-AKI after cerebrovascular angiography and intervention. Conclusion Chronic kidney disease (eGFR<60 mL/[min·1. 73 m2 ]),diabetes,anemia,and old age (age >60 years)are the independent risk factors for occurring CI-AKI after cerebrovascular angiography and intervention.

Since the International guidelines for groin hernia management were published in 2018,many new evidences have been published.In October 2023,the HerniaSurge Group published Update of the international HerniaSurge guidelines for groin hernia management.It updated eight chapters of the last guidelines,proposed 20 key questions,and 39 new statements and 32 recommendations,of which 16 were strong recommendations.This article combined clinical concerns to sort out and interpret the updated version.
