ABSTRACT
OBJECTIVE@#To investigate the fetal and maternal outcomes, risk factors of disease progression and adverse pregnancy outcomes (APOs) in patients with undifferentiated connective tissue disease (UCTD).@*METHODS@#This retrospective study described the outcomes of 106 pregnancies in patients with UCTD. The patients were divided into APOs group (n=53) and non-APOs group (n=53). The APOs were defined as miscarriage, premature birth, pre-eclampsia, premature rupture of membranes (PROM), intrauterine growth restriction (IUGR), postpartum hemorrhage (PPH), and stillbirth, small for gestational age infant (SGA), low birth weight infant (LBW) and birth defects. The differences in clinical manifestations, laboratory data and pregnancy outcomes between the two groups were compared. Logistic regression analysis was performed to analyze the risk factors for APOs and the progression of UCTD to definitive CTD.@*RESULTS@#There were 99 (93.39%) live births, 4 (3.77%) stillbirths and 3 (2.83%) miscarriage, 20 (18.86%) preterm delivery, 6 (5.66%) SGA, 17 (16.03%) LBW, 11 (10.37%) pre-eclampsia, 7 (6.60%) cases IUGR, 19 (17.92%) cases PROM, 10 (9.43%) cases PPH. Compared with the patients without APOs, the patients with APOs had a higher positive rate of anti-SSA antibodies (73.58% vs. 54.71%, P=0.036), higher rate of leukopenia (15.09% vs. 3.77%, P=0.046), lower haemoglobin level [109.00 (99.50, 118.00) g/L vs. 124.00 (111.50, 132.00) g/L, P < 0.001].Multivariate Logistic regression analysis showed that leucopenia (OR=0.82, 95%CI: 0.688-0.994) was an independent risk factors for APOs in UCTD (P=0.042). Within a mean follow-up time of 5.00 (3.00, 7.00) years, the rate of disease progression to a definite CTD was 14.15%, including 8 (7.54%) Sjögren's syndrome, 4 (3.77%) systemic lupus erythematosus (SLE), 4 (3.77%) rheumatoid arthritis and 1 (0.94%) mixed connective tissue disease. Multivariate Cox proportional risk regression analysis showed that Raynaud phenomenon (HR=40.157, 95%CI: 3.172-508.326) was an independent risk factor for progression to SLE.@*CONCLUSION@#Leukopenia is an independent risk factor for the development of APOs in patients with UCTD. Raynaud's phenmon is a risk factor for the progression of SLE. Tight disease monitoring and regular follow-up are the key measures to prevent adverse pregnancy outcomes and predict disease progression in UCTD patients with pregnancy.

<p><b>BACKGROUND</b>Antimicrobial resistance is a serious problem that compromises the empirical treatment of infections, resulting in a lack of effective antibiotics and high medical expenses. Here, we aimed to monitor the trends in antimicrobial resistance among Enterobacteriaceae isolated from blood samples in mainland China.</p><p><b>METHODS</b>A total of 2240 Enterobacteriaceae isolates from blood were collected from hospitalized patients at 19 tertiary hospitals between October 2004 and June 2014. The minimum inhibitory concentrations of all isolates were determined using the agar dilution method according to the Clinical and Laboratory Standards Institute 2016 guidelines.</p><p><b>RESULTS</b>The most commonly isolated bacteria were Escherichia coli, compromising 47.0% (1053/2240) of the total isolates, followed by Klebsiella spp. (26.3%), Salmonella spp. (10.4%), and Enterobacter spp. (9.2%). The detection rates of extended-spectrum β-lactamases (ESBLs) among E. coli were 68.9% (2004-2005), 73.2% (2007-2008), 67.9% (2009-2010), 72.6% (2011-2012), and 58.4% (2013-2014), whereas those in ESBL-producing Klebsiella pneumoniae were slightly decreased (75.9%, 50.0%, 41.4%, 40.2%, and 43.0%, respectively). Carbapenems were the most potent agents against the Enterobacteriaceae isolates, followed by moxalactam, tigecycline, and amikacin. However, there was a decrease in the susceptibility rates for carbapenems in all species, particularly K. pneumoniae(decreased by 10.6% for imipenem) and Enterobacter aerogenes (decreased by 21.1% for imipenem). Reviving antibiotics (tigecycline and polymyxins) showed good in vitro activity against Enterobacteriaceae.</p><p><b>CONCLUSIONS</b>The activity of antibiotics against Enterobacteriaceae isolated from blood was decreased overall. Large proportions of ESBL-producing isolates were identified among E. coli and Klebsiella spp. Carbapenem-resistant isolates have become a major challenge in the treatment of infections.</p>
ABSTRACT
Objective:To explore the prognostic value for circulating monocyte subsets combining left ventricular ejection fraction (LVEF) in patients with acute ST-segment elevation myocardial infarction (STEMI).Methods:STEMI patients admitted within 24 h of onset received PCI in Pingjin hospital heart center were enrolled.Flow cytometry (FCM) was used to examine 3 subsets of monocyte in peripheral blood as classical CD14++CD16-monocyte,intermediate CD14++CD16+ monocyte and non-classical CD14+CD16++ monocyte.The patients were followedup in 3 years for major adverse cardiac events (MACE) occurrence.The relationship between monocyte subsets,LVEF and MACE occurrence was studied by COX model analysis and MACE prediction model was established by ROC combining multivariate Logistic regression analysis.Results:There were 50/221 patients suffered from MACE during 3-year follow-up period.Compared with Non-MACE patients,MACE patients had the elder age (63.82±11.88) years vs (58.84±11.40) years,P=0.009;more diabetes mellitus (28.0％ vs 18.7％),P＜0.001;higher blood levels of LDL-C (2.77 mmol/L) vs (2.41 mmol/L),P=0.003 and CD14++CD16+ monocyte (47.17 cells/μl) vs (21.47 cells/μl),P＜0.001;lower LVEF (52％ vs 46％),P＜0.001.Multivariate Cox analysis indicated that CD14++CD16+ (HR=2.211,95％ CI 1.211-3.635,P=0.016) and LVEF (HR=2.014,95％ CI 1.038-2.933,P=0.022) were the independent risk factors for MACE occurrence in STEMI patients.ROC combining multivariate Logistic regression analysis presented that MACE predictive value of CD14++CD16+ monocyte combining LVEF (AUC=0.744,95％ CI 0.664-0.823,P＜0.001) was higher than the single value of CD14++CD16+ monocyte (AUC=0.683,95％ CI 0.598-0.768,P＜0.001) and LVEF(AUC=0.640,95％ CI 0.552-0.7291,P=0.003) respectively.Conclusion:Circulating level of CD14++CD16+ monocyte combining LVEF may predict MACE occurrence within 3 years in STEMI patients;it had potential value in clinical practice.
