Objective The study aimed to investigate the impact of rare earth elements(REEs)exposure on pregnancy outcomes of in vitro fertilization-embryo transfer(IVF-ET)by analyzing samples from spouses. Methods A total of 141 couples were included.Blood and follicular fluid from the wives and semen plasma from the husbands,were analyzed for REEs using inductively coupled plasma mass spectrometry(ICP-MS).Spearman's correlation coefficients and the Mann-Whitney U test were used to assess correlations and compare REE concentrations among three types of samples,respectively.Logistic models were utilized to estimate the individual REE effect on IVF-ET outcomes,while BKMR and WQS models explored the mixture of REE interaction effects on IVF-ET outcomes. Results Higher La concentration in semen(median 0.089 ng/mL,P=0.03)was associated with a lower fertilization rate.However,this effect was not observed after artificial selection intervention through intracytoplasmic sperm injection(ICSI)(P=0.27).In semen,the REEs mixture did not exhibit any significant association with clinical pregnancy. Conclusion Our study revealed a potential association between high La exposure in semen and a decline in fertilization rate,but not clinical pregnancy rate.This is the first to report REEs concentrations in follicular fluid with La,Ce,Pr,and Nd found at significantly lower concentrations than in serum,suggesting that these four REEs may not accumulate in the female reproductive system.However,at the current exposure levels,mixed REEs exposure did not exhibit reproductive toxicity.

Objective: To explore the correlation between Diabetes Complication Severity Index(DCSI), C-reactive protein/albumin ratio(CAR) and death in patients with diabetic foot ulcer(DFU) and to clarify their predictive value for all-cause death in DFU patients. Methods: Retrospectively analyzed the clinical data of 354 DFU patients who were treated in the Endocrinology Department of the First Affiliated Hospital of Anhui Medical University from July 2019 to December 2022. Based on survival status during follow-up, patients were divided into a survival group(n=268) and a death group(n=86). Univariate and multivariate Cox regression analyses were used to identify risk factors for all-cause death in DFU patients. Receiver operating characteristic(ROC) curves were plotted to evaluate the predictive value of DCSI, CAR, and their combination for all-cause death in DFU patients. Kaplan-Meier curves were used to explore the impact of different DCSI and CAR levels on survival in DFU patients. Results: Univariate Cox regression analysis showed that older age, history of hypertension, higher Wagner classification levels, and elevated levels of CRP, Scr, FDP, DCSI score, and CAR were associated with a higher risk of death in DFU patients(P<0.05). Higher levels of HGB, HCT, ALB, or eGFR were associated with a lower risk of death. Patients receiving combined insulin and oral hypoglycemic medication had a lower risk of death compared to those receiving only insulin therapy(P<0.05). Multivariate Cox regression analysis indicated that older age, higher levels of Scr, DCSI, and CAR were independent risk factors for all-cause death in DFU patients, while higher levels of ALB and combined insulin and oral hypoglycemic therapy were protective factors. ROC curve analysis showed that the AUC values for DCSI, CAR, and their combination were 0.652, 0.633, and 0.686, respectively. Kaplan-Meier curve analysis revealed that patients with high DCSI scores(≥4.5) had a lower survival rate compared to those with lower DCSI scores(<4.5). Similarly, patients with high CAR levels(≥0.124) had a lower survival rate compared to those with lower CAR levels(<0.124). Conclusion High levels of DCSI and CAR are independent risk factors for all-cause death in DFU patients. DCSI, CAR, and their combination have predictive value for all-cause mortality in DFU patients.

BACKGROUNDA number of studies have demonstrated the rates of overall and aneurysm-related mortality and morbidity in Western populations. The cardiovascular risk factors influencing postoperative outcome have been also reported. Until recently, little has been known about the prognosis in this patient cohort in the Chinese population. We evaluated the independent predictors of mortality and morbidity in abdominal aortic aneurysm (AAA) patients undergoing elective surgical treatment and emphasized whether the coronary artery revascularization could have any effect on the overall mortality and morbidity in patients following the current guideline recommendation.

METHODSA total of 386 patients (174 women) undergoing surgery in Beijing Anzhen Hospital from January 2008 to June 2010 were enrolled (mean age (70.6±10.5) years). Kaplan-Meier curves were constructed to compare the mortality and morbidity of AAA patients with coronary artery revascularization and those without. A Cox proportional hazards model was constructed to identify clinical factors associated with two-year outcomes. The primary outcomes were death from any cause, the pre-specified morbidity was re-hospitalization for pulmonary conditions, congestive heart failure, angina, ischemic/hemorrhagic stroke.

RESULTSDuring the two-year follow-up, 34 patients died and 65 experienced re-hospitalization with pulmonary conditions, congestive heart failure, angina, or ischemic/hemorrhagic stroke. Kaplan-Meier survival analysis showed that the AAA patients with cardiac revascularization had no higher incidence of overall mortality and major morbidity than those without (log-rank test P = 0.35 and P = 0.40, respectively). Cox proportional hazards regression analysis showed that level of lowdensity lipoprotein (HR, 4.06; 95% CI: 1.19-18.7, P = 0.027) and AAA size (HR, 2.18; 95% CI: 1.28-11.65, P = 0.036) were independently associated with the incidence of overall mortality. Long-term use of angiotensin converting enzyme inhibitors, statins, AAA size and systolic blood pressure were independent predictors of the secondary pre-specified outcomes.

CONCLUSIONSCoronary artery revascularization following the guideline recommendations did not increase the mortality and morbidity of Chinese with AAA who were undergoing repair. Absence of angiotensin converting enzyme inhibitors and statins, AAA size, and systolic blood pressure were powerful predictors of the clinical events.
