Objective

Adipophilin is a lipid droplet-associated protein, and its expression has been correlated with aggressive clinical behavior in some types of carcinomas, though its role in pancreatic ductal adenocarcinoma (PDAC) has not been clarified. This study aimed to evaluate the role of adipophilin in PDAC.

Methods

By immunohistochemical staining using tissue microarrays, we analyzed the expression profiles of adipophilin in 181 consecutive PDAC patients who underwent macroscopic margin-negative resection from January 2008 to December 2015. Overall survival (OS) and recurrence-free survival (RFS) were compared based on adipophilin expression, and the risk factors for OS, RFS, and early recurrence (within 6 months) were analyzed.

Results

Of the 181 evaluated patients, 51 (28.2%) were positive for adipophilin expression. A histopathological grade of 3 (p?=?0.0012), higher CA19-9 level (p?=?0.0016), and R1 status (p?=?0.028) were significantly associated with adipophilin-positive patients who had significantly poor OS and RFS compared to those associated with adipophilin-negative patients (p?=?0.0007 and p?=?0.0022, respectively). They also showed a significantly higher incidence of early recurrence (p?=?0.030), based on multivariate analyses.

Conclusions

Adipophilin is a potential independent prognostic marker for PDAC.  相似文献

Objectives

This study aimed to use a retrospective data base to investigate whether a standard lymphadenectomy during distal pancreatectomy should include the No. 9 lymph nodes (LNs) for resectable pancreatic ductal adenocarcinoma (PDAC) located in the body and tail of the pancreas.

Methods

Data from 169 patients undergoing curative distal pancreatectomy for PDAC between Jan 1, 2013 and Dec 31, 2016 were collected. According to the tumor location, patients were divided into three groups: pancreatic neck tumor, pancreatic body and tail tumor with margin-to-bifurcation-distance (MTBD)?≤?2.5?cm and pancreatic body and tail tumor with MTBD?>?2.5?cm. The metastatic rate of the No. 9 LNs was compared among the 3 groups. The survival outcomes were analyzed.

Results

The involvement rate for No. 9 LNs was 20.7% (6/29) for pancreatic neck tumors, 17.6% (15/85) for body and tail tumors with MTBD?≤?2.5?cm and 1.8% (1/55) for MTBD?>?2.5?cm. The No. 9 LNs were significantly more frequently involved in neck or body and tail tumors with MTBD ≤2.5?cm than with the cases with MTBD >2.5?cm (OR 0.082, P?=?0.016). No. 9 LN involvement was not associated with worse survival compared with survival associated with involvement of other LNs (P?=?0.780).

Conclusions

For PDAC located in the neck or in the body and tail of the pancreas with MTBD?≤?2.5?cm, the involvement rate for No. 9 LNs is high. Standard lymphadenectomy should include the No. 9 LNs.  相似文献

Background/Objectives

A breakthrough in chemotherapy for pancreatic ductal adenocarcinoma (PDAC) may be achieved using precision medicine, which involves identifying cases that are highly likely to respond to a certain treatment and then performing that treatment. BRCAness has been receiving attention as a novel predictor of anticancer drug sensitivity in PDAC, making the screening of BRCAness paramount.

Methods

We conducted the first-ever examination of the feasibility of analyzing BRCAness using multiplex ligation-dependent probe amplification (MLPA). Formalin-fixed paraffin-embedded (FFPE) tissue samples obtained via endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) from 20 patients with the highest pancreatic carcinoma cell counts in tissue samples out of 40 consecutive PDAC patients who underwent EUS-FNAB at our hospital were analyzed by MLPA for BRCAness.

Results

We were able to accurately analyze BRCAness in 75% of the 20 cases of PDAC using FFPE tissue obtained by EUS-FNAB. BRCAness was observed in one of the 20 cases.

Conclusions

In PDAC, analyzing BRCAness by MLPA using FFPE tissue obtained by EUS-FNAB offers the remarkable benefit of yielding results in a short period of time and at a low cost. In addition, this method of BRCAness analysis may prove to be a feasible and effective approach for performing precision medicine.  相似文献

Background

The clinicopathological and prognostic features of insulinoma with synchronous metastases are unclear. This study aimed to verify the distinct clinicopathological and prognostic features of insulinoma with synchronous distant metastasis.

Methods

Patients with pancreatic neuroendocrine tumor (PanNET) were retrospectively enrolled and divided into cohort 1 (Fudan University Shanghai Cancer Center) and cohort 2 (Surveillance, Epidemiology, and End Results Program database). Both cohorts were further divided into three subgroups: insulinoma, nonfunctioning pancreatic neuroendocrine tumor (NF-PanNET), and non-insulinoma functioning pancreatic neuroendocrine tumor (NiF-PanNET).

Results

Cohorts 1 and 2 comprised 505 and 2761 patients (1566 M0 patients and 1195 M1 patients), respectively. In cohort 1 and cohort 2 M0 subgroup, insulinoma showed longer disease-free survival, overall survival (OS), and disease-specific survival (DSS) than NiF-PanNET and NF-PanNET (not reached vs. 48 and 60months, p?<?0.001; 183months vs. 87 and 109months, p?<?0.001; 247months vs. 121 and 140months, p?=?0.002). However, in cohort 2 M1, the mDSS for metastatic insulinoma was shorter than that for NiF-PanNET (31months vs. 61months, p?=?0.045), while the mDSS and mOS were similar to those for NF-PanNET. The percentage of T1 and N0 patients was similar between the metastatic insulinoma subgroup and NiF-PanNET and NF-PanNET subgroups. The Ki-67 index and recurrence had a positive linear relationship only for NiF-PanNET and NF-PanNET (p?=?0.009).

Conclusions

Insulinoma with synchronous metastasis showed clinicopathological and prognostic characteristics similar to those of NF-PanNET. Metastatic insulinoma had worse prognosis than non-insulinoma F-PanNET. These findings may help in the clinical management of metastatic insulinoma.  相似文献

Background

This systematic review aimed to define the outcomes of different pancreatic resection procedures for multiple endocrine neoplasia type 1 (MEN1) associated pancreatic neuroendocrine neoplasms (pNENs).

Methods

A search of PubMed, MEDLINE and SCOPUS databases were performed in accordance with PRISMA guidelines.

Results

Twenty-seven studies including 533 patients undergoing initial pancreatic resection for MEN1 associated pNENs were included in this systematic review. Three hundred and sixty-six (68.7%) distal pancreatectomies (DP), 120 (22.5%) sole enucleations (SE) and 47 (8.8%) pancreaticoduodenectomies (PD) were identified. SE was associated with a higher rate of recurrence than DP (25/67, 37% vs 40/190, 21% respectively, P?=?0.008) but a lower rate of endocrine insufficiency than PD (1/20, 5% vs 8/21, 38% respectively, P?=?0.010). A meta-analysis of major pancreatic resections (PD or DP) vs SE in 15 studies showed that SE is associated with an increased rate of recurrence (Major resection 42/184, 23% vs SE 20/53, 38% RR 0.65 CI 0.43–0.96?P?=?0.032) but reduced rate of postoperative endocrine insufficiency (Resection 37/93, 40% vs SE 0/24, 0% RR 7.37 CI 1.57–34.64?P?=?0.008). Similarly, insulinomas and functional pNENs overall had lower rates of recurrence and reoperation with major resection. There was no difference in the reoperation rates or survival outcomes after SE compared with major pancreatic resections at follow-up (pooled overall mean duration: 85 months).

Conclusion

Major pancreatic resections for MEN1 associated pNENs have a lower risk of recurrence and a higher risk of postoperative endocrine insufficiency when compared to sole enucleation, but a similar rate of reoperation and survival.  相似文献

Background

There are conflicting data regarding the relative effectiveness of renal sympathetic denervation (RSD) in patients with hypertension.

Objectives

The purpose of this study was to evaluate the blood pressure (BP) response after RSD in sham-controlled randomized trials.

Methods

Databases were searched through June 30, 2018. Randomized trials (RCTs) with ≥50 patients comparing catheter-based RSD with a sham control were included. The authors calculated summary treatment estimates as weighted mean differences (WMD) with 95% confidence intervals (CIs) using random-effects meta-analysis.

Results

The analysis included 977 patients from 6 trials. The reduction in 24-h ambulatory systolic blood pressure (ASBP) was significantly greater for patients treated with RSD than sham procedure (WMD ?3.65 mm Hg, 95% CI: ?5.33 to ?1.98; p < 0.001). Compared with sham, RSD was also associated with a significant decrease in daytime ASBP (WMD ?4.07 mm Hg, 95% CI: ?6.46 to ?1.68; p < 0.001), office systolic BP (WMD ?5.53 mm Hg, 95% CI: ?8.18 to ?2.87; p < 0.001), 24-h ambulatory diastolic BP (WMD ?1.71 mm Hg, 95% CI: ?3.06 to ?0.35; p = 0.01), daytime ambulatory diastolic BP (WMD ?1.57 mm Hg, 95% CI: ?2.73 to ?0.42; p = 0.008), and office diastolic BP (WMD ?3.37 mm Hg, 95% CI: ?4.86 to ?1.88; p < 0.001). Compared with first-generation trials, a significantly greater reduction in daytime ASBP was observed with RSD in second-generation trials (6.12 mm Hg vs. 2.14 mm Hg; p interaction = 0.04); however, this interaction was not significant for 24-h ASBP (4.85 mm Hg vs. 2.23 mm Hg; p interaction = 0.13).

Conclusions

RSD significantly reduced blood pressure compared with sham control. Results of this meta-analysis should inform the design of larger, pivotal trials to evaluate the long-term efficacy and safety of RSD in patients with hypertension.  相似文献

Background

Endothelial cell dysfunction has been described in Behçet disease (BD) not only as a cause of major vascular events but also related to chronic inflammation in different organ systems.

Aim of the work

To study the relation of serum endocan, a marker of endothelial dysfunction, with clinical manifestations and disease activity in BD patients.

Patients and methods

This study included 23 BD patients and 23 matched controls. Disease activity was assessed by the Behcet Disease Current Activity Form (BDCAF). Serum endocan was measured in all subjects.

Results

The mean age of the patients was 32.5?±?6.8?years and they were 16 males and 7 females (M:F 2.3:1) with mean disease duration of 7?±?5.2?years. Their mean BDCAF was 2.26?±?1.32. A significant difference was found between serum endocan level among active patients 328.24?±?195.3?ng/L, inactive patients (169.8?±?35.7?ng/L) and controls (160.6?±?39.7?ng/L)(p?=?0.001). Patients with genital ulcers, papulopastular lesions and arthritis at the time of the study had higher serum endocan level than those without (p?=?0.002, p?=?0.006 and p?=?0.0001 respectively). Serum endocan levels correlated significantly with the BDCAF, neutrophil/lymphocyte ratio, platelet lymphocyte ratio and C-reactive protein (r?=?0.94, p?=?0.0001; r?=?0.82, p?=?0.0001, r?=?0.44, p?=?0.04 and r?=?0.48, p?=?0.02 respectively). The optimum serum endocan cut-off point for active BD was 191.5?ng/L with a sensitivity and specificity of 100% and 86% respectively (area under curve 0.99, 95% confidence interval 0.96-1).

Conclusion

Serum endocan may serve as a potential marker of disease activity in BD. Patients with genital ulcers, papulopastular lesions and arthritis showed higher serum endocan levels.  相似文献

Background

A combination of circulating biomarkers associated with excessive myocardial collagen type-I cross-linking or CCL+ (i.e., decreased carboxy-terminal telopeptide of collagen type-I to matrix metalloproteinase-1 ratio) and with excessive myocardial collagen type-I deposition or CD+ (i.e., increased carboxy-terminal propeptide of procollagen type-I) has been described in heart failure (HF) patients and associates with poor outcomes.

Objectives

The purpose of this study was to investigate whether the CCL+CD+ combination of biomarkers associates with atrial fibrillation (AF).

Methods

Biomarkers were analyzed in serum samples from 242 HF patients (study 1) and 150 patients referred for AF ablation (study 2). Patients were classified into 3 groups (CCL?CD?, CCL+CD? or CCL?CD+, and CCL+CD+) in accordance to biomarker threshold values. Left atrial electroanatomic high-density mapping was performed in 71 patients from study 2.

Results

In study 1, 53.7% patients had AF at baseline and 19.6% developed AF (median follow-up 5.5 years). Adjusted odds and hazard ratios associated with baseline and new-onset AF, respectively, were both ≥3.3 (p ≤ 0.050) in CCL+CD+ patients compared with CCL?CD? patients, with nonsignificant changes in the other group. In study 2, 29.3% patients had AF recurrence during 1-year post-ablation. The adjusted hazard ratio for AF recurrence was 3.4 (p = 0.008) in CCL+CD+ patients compared with CCL?CD? patients, with nonsignificant changes in the other group. The CCL+CD+ combination added incremental predictive value over relevant covariables. CCL+CD+ patients exhibited lower left atrial voltage than the remaining patients (p = 0.005).

Conclusions

A combination of circulating biomarkers reflecting excessive myocardial collagen type-I cross-linking and deposition is associated with higher AF prevalence, incidence, and recurrence after ablation.  相似文献

Aim of the work

To measure serum peptidyl arginine deiminase (PADI4) enzyme level in rheumatoid arthritis (RA) patients and to assess its role in diagnosis and monitoring patient improvement.

Patients and methods

The study included 31 RA patients and 10 age and sex matched healthy controls. Serum PADI4 and anti-cyclic citrullinated peptide (anti-CCP) were measured. Disease activity score (DAS28) was calculated. Patients were followed-up at 3 months with measurement of serum PADI4, anti-CCP and DAS28.

Results

Mean age of the patients was 42.4?±?7.8 years, female:male?=?5.2:1 and disease duration 8.1?±?5.4 years. The DAS28 was 5?±?1.2 and modified health assessment questionnaire (MHAQ) was 0.8?±?0.6. Mean anti-CCP (129.3?±?74.8?ng/ml) and PADI-4 levels (532.9?±?240.9?pg/ml) in patients were significantly higher than in controls (8.4?±?4.4?ng/ml and 156?±?31?pg/ml respectively; p?<?0.001 both). At a cut-off value?≥?250?pg/ml, PADI4 was highly diagnostic for RA (sensitivity 90.3%, specificity 100%; area under curve?=?0.97 with no significant difference from anti-CCP at a cut-off of 15 ng/ml (sensitivity 93.5%, specificity 100%; AUC ?=?0.99). Serum PADI4 level showed a significant correlation with DAS28 (r?=?0.49, p?=?0.047). At follow up (n?=?20), no significant difference in PADI4, anti-CCP level or DAS28 scores was found but changes in serum PADI4 level significantly correlated with changes in DAS28 (r?=?0.82, p?<?0.001). Mean serum PADI4 level was significantly lower in improved patients (184.4?±?10.2?pg/ml) compared to unimproved (563.3?±?251.9?pg/ml, p?<?0.001).

Conclusion

Serum PADI4 was diagnostic for RA and comparable with anti-CCP. It correlated with disease activity and could be a promising follow up marker of remission.  相似文献

Background

Intrahepatic cholangiocarcinoma (ICC) is the second most common malignancy arising from the liver. Fibulin-1 has been demonstrated to be involved in various cancers, however, its role in ICC remains unclear.

Methods

To study the clinical value and potential molecular mechanism of Fibulin-1 in ICC, immunohistochemistry and bioinformatic analyses were performed using data in the Gene Expression Omnibus Datasets and The Cancer Genome Atlas database.

Results

Fibulin-1 expression was overexpressed in ICC tissues compared with adjacent non-cancerous tissues, and was significantly associated with unfavorable overall survival. Moreover, similar genes were identified by Gene Expression Profiling Interactive Analysis and microarray data set. Next, functional and pathway enrichment analysis demonstrated that Fibulin-1 was overrepresented in the pathways of extracellular matrix organization and angiogenesis, which are associated with tumor progression and potential for metastasis. Gene set enrichment analysis indicated that the gene sets of epithelial mesenchymal transition, TGF-beta signaling pathway and angiogenesis were enriched in tissues with high Fibulin-1 level. Furthermore, Fibulin-1 silencing suppressed the ability of ICC tumor cells to form colonies and siFibulin-1 repressed the endogenous protein level of p-AKT.

Conclusion

Collectively, this study suggests that Fibulin-1 overexpression may play key roles in the carcinogenesis and progression of ICC via regulation of tumor-related pathways.  相似文献

Background

Patients with atrial fibrillation (AF) have an increased risk of cognitive decline, potentially resulting from clinically unrecognized vascular brain lesions.

Objectives

This study sought to assess the relationships between cognitive function and vascular brain lesions in patients with AF.

Methods

Patients with known AF were enrolled in a multicenter study in Switzerland. Brain magnetic resonance imaging (MRI) and cognitive testing using the Montreal Cognitive Assessment (MoCA) were performed in all participants. Large noncortical or cortical infarcts (LNCCIs), small noncortical infarcts (SNCIs), microbleeds, and white matter lesions were quantified by a central core laboratory. Clinically silent infarcts were defined as infarcts on brain MRI in patients without a clinical history of stroke or transient ischemic attack.

Results

The study included 1,737 patients with a mean age of 73 ± 8 years (28% women, 90% taking oral anticoagulant agents). On MRI, LNCCIs were found in 387 patients (22%), SNCIs in 368 (21%), microbleeds in 372 (22%), and white matter lesions in 1715 (99%). Clinically silent infarcts among the 1,390 patients without a history of stroke or transient ischemic attack were found in 201 patients with LNCCIs (15%) and 245 patients with SNCIs (18%). The MoCA score was 24.7 ± 3.3 in patients with and 25.8 ± 2.9 in those without LNCCIs on brain MRI (p < 0.001). The difference in MoCA score remained similar when only clinically silent LNCCIs were considered (24.9 ± 3.1 vs. 25.8 ± 2.9; p < 0.001). In a multivariable regression model including all vascular brain lesion parameters, LNCCI volume was the strongest predictor of a reduced MoCA (β = ?0.26; 95% confidence interval: ?0.40 to ?0.13; p < 0.001).

Conclusions

Patients with AF have a high burden of LNCCIs and other brain lesions on systematic brain MRI screening, and most of these lesions are clinically silent. LNCCIs were associated with worse cognitive function, even among patients with clinically silent infarcts. Our findings raise the question of MRI screening in patients with AF.  相似文献

Background

Perihilar cholangiocarcinoma (PHC) often requires extensive surgery which is associated with substantial morbidity and mortality. This study aimed to compare an Eastern and Western PHC cohort in terms of patient characteristics, treatment strategies and outcomes including a propensity score matched analysis.

Methods

All consecutive patients who underwent combined biliary and liver resection for PHC between 2005 and 2016 at two Western and one Eastern center were included. The overall perioperative and long-term outcomes of the cohorts were compared and a propensity score matched analysis was performed to compare perioperative outcomes.

Results

A total of 210 Western patients were compared to 164 Eastern patients. Western patients had inferior survival compared to the East (hazard-ratio 1.72 (1-23-2.40) P < 0.001) corrected for age, ASA score, tumor stage and margin status. After propensity score matching, liver failure rate, morbidity, and mortality were similar. There was more biliary leakage (38% versus 13%, p = 0.015) in the West.

Conclusion

There were major differences in patient characteristics, treatment strategies, perioperative outcomes and survival between Eastern and Western PHC cohorts. Future studies should focus whether these findings are due to the differences in the treatment or the disease itself.  相似文献

Objectives

This study sought to examine depression prevalence among chronic total occlusion (CTO) patients and compared symptom improvement among depressed and nondepressed patients after percutaneous coronary intervention (PCI).

Background

Depression in cardiovascular patients is common, but its prevalence among CTO patients and its association with PCI response is understudied.

Methods

Among 811 patients from the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry, we evaluated change in health status between baseline and 1-year post-PCI, as measured by the Seattle Angina Questionnaire (SAQ) and the Rose Dyspnea Score. Depression was defined using the Personal Health Questionnaire-8. The independent association between health status and depression following PCI was assessed using multivariable regression.

Results

Among the 811 patients, 190 (23%) screened positive for major depression, of whom 6.3% were on antidepressant therapy at intervention. Depressed patients experienced more baseline angina, but by 1-year post-PCI they experienced greater improvements than nondepressed patients (change in SAQ Summary: 31.4 ± 22.4 vs. 24.2 ± 20.0; p < 0.001). After adjustment, baseline depressed patients had more improvement in health status (adjusted difference in SAQ Summary improvement, depressed vs. nondepressed: 5.48 ± 1.81; p = 0.003).

Conclusions

Depression is common among CTO PCI patients, but few were treated with antidepressants at baseline. Depressed patients had more severe baseline angina and significant improvement in health status after PCI. (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion [OPEN-CTO]; NCT02026466)  相似文献

Background

The ISGPS classification of post-operative pancreatic fistula (POPF) was recently revised, introducing the concept of biochemical leak (BL) which replaced grade A POPF. More recently, an additional distinction on three different subclasses for grade B (B1–B3) POPF was proposed. The aim of this study was to evaluate the impact of these modifications in clinical practice.

Methods

All pancreatico-duodenectomies (PD) and distal pancreatectomies (DP) performed between 2010 and 2016 were retrospectively evaluated. Incidence and grade of POPF using the old and new ISGPS classification were evaluated. Three grade B subclasses (B1: maintenance of abdominal drain >3 weeks; B2: adoption of specific medical treatments for POPF; B3: use of radiological procedures) were evaluated for clinical severity.

Results

A total of 716 patients (502 PD, 214 DP) were evaluated. The new ISGPS classification reduced the reported rate of POPF (30.7% vs 35.2% for PD, p?>?0.05; 28% vs 44.9% for DP, p?<?0.05), due to the abolition of grade A POPF. Grade B1, B2 and B3 rates were 3.1%, 73.8% and 23.1% in PD and 12.3%, 47.4% and 40.3% in DP, respectively. Passing from B1 to B3, significant increases in wound infection (0–40%), mean length of stay in PD (14.7–22.5 days; p?<?0.05) and readmission rate in DP (0–39.1%) were observed.

Conclusions

The new ISGPS classification significantly reduces the reported rate of POPF, particularly after DP. The three different grade B subclasses (B1–B3) better discriminate the severity of post-operative course, especially after PD.  相似文献

Background

The diagnosis of early rheumatoid arthritis (RA) is challenging. B-cell chemokine (CXCL13) plays a critical role in the disease pathogenesis.

Aim of the work

To assess the diagnostic value of serum CXCL13 in early RA and compare it with rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies.

Patients and methods

The study included 60 RA patients; 30 early, 30 established RA and 30 healthy controls. The modified health assessment questionnaire (MHAQ), modified Sharp-van der Heijde score (MSS) and disease activity score (DAS28) were assessed in RA patients. RF, anti-CCP and serum level of CXCL13 were measured.

Results

Patients had a mean age of 39?±?7.4?years and disease duration of 4.4?±?5.7?years; they were 46 females and 12 males (F:M 3.8:1). Serum CXCL13 was significantly higher in early (191.7?±?74.4?pg/ml) compared to established (136.4?±?79?pg/ml) RA (p?=?0.007) which were not observed with RF and anti-CCP; both were higher than in control (30.4?±?13.5?pg/ml) (p?<?0.001). In early RA, the frequencies of CXCL13, RF and anti-CCP positivity were 90%, 73.3% and 56.7% while in the established cases the frequencies were 36.7%, 66.7% and 63.3% respectively. CXCL13 significantly correlated with DAS28 (early: 0.49, p?=?0.006; established: r?=?0.38, p?=?0.04) but not with MHAQ or MSS. The CXCL13 significantly correlated with both the RF and anti-CCP in both early and established cases (p?<?0.001).

Conclusion

CXCL13 is an important for the diagnosis of early RA with a superior diagnostic performance compared to RF and anti-CCP. It may also be considered a potential biomarker of disease activity.  相似文献

Background

Numerous tools to assess activity of rheumatoid arthritis (RA) are available to use. For any marker to be a more appropriate indicator of disease activity, it should be more authentic to the patho-physiologic basis of the disease.

Aim of the work

To determine the performance of serum adenosine deaminase (sADA) in measuring disease activity in RA.

Patients and Methods

100 RA patients and 100 matched controls were included in the study. The disease activity score (DAS28) with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were assessed. sADA level was determined by spectrophotometry. The sADA level was integrated in the DAS28 formulae and the corresponding values were determined.

Results

The mean age of the RA patients was 61.8?±?9.7?years, 68% were females and they had a disease duration of 12.5?±?3.7?years. The mean DAS28-ESR was 4.2?±?1.3 and DAS28-CRP 3.5?±?1.1. The mean sADA was significantly higher in the patients (33.6?±?11.6?U/L) compared to the control (25.1?±?9.9?U/L) (p?<?0.001). The sADA level and DAS28-sADA did not differ according to the gender, methotrexate use, rheumatoid factor or anti-citrullinated protein autoantibodies positivity. The mean DAS28-sADA significantly increased in higher activity categories (p?<?0.001). sADA significantly correlated with the disease activity parameters. DAS28-sADA significantly correlated with DAS28-ESR (r?=?0.57, p?<?0.001) and DAS28-CRP (r?=?0.604, p?<?0.001). DAS28-sADA showed a sensitivity of 0.9 and specificity 0.69 for detection of disease activity measured with DAS28-ESR and was 0.88 and 0.65 when measured with DAS28-CRP.

Conclusion

Integration of sADA in the DAS28 index can be a useful marker that reflects RA activity.  相似文献

Objective

To determine the common mutations responsible for rifampicin resistance in TB cases detected by Xpert MTB/RIF assay.

Design

Results of Xpert MTB/RIF assay performed from 2013 to 2017 were analysed for missing probes in different types of specimens containing rifampicin resistant MTB.

Results

Successful results were obtained in14872 of the total 15129 specimens processed by Xpert MTB/RIF assay, of which 9458 (63.6%) were sputum and 5414 (36.4%) were extrapulmonary specimens. MTB was detected in 1624 (17.17%) sputum and 1121 (20.70%) extrapulmonary specimens of which 409 (25.18%) and 277 (24.71%) were rifampicin resistant respectively.Probe E (83.82%) was the commonest probe responsible for rifampicin resistance followed by D (3.93%) and B (3.79%). Mutation in probe C (0.29%) was very rare. Combination of missing probes like AB (0.73%), DE (1.16%) and ADE (0.14%) was observed. 22 (3.2%) specimens showed presence of all five probes.

Conclusion

Xpert MTB/RIF assay uses various combinations of probe to detect MTB along with rifampicin resistance and is a valuable diagnostic tool. It can become a useful epidemiological tool to identify dynamics of transmission of TB by addition of few more probes to identify mutations at specific codons.  相似文献

Background

Liver steatosis is associated with poor outcome after liver transplantation and liver resection. There is a need for an accurate and reliable intraoperative tool to identify and quantify steatosis. This study aimed to investigate whether surface diffuse reflectance spectroscopy (DRS) measurements could detect liver steatosis on humans during liver surgery.

Methods

The DRS instrumentation setup consists of a computer, a high-power tungsten halogen light source and two spectrometers, connected through a trifurcated optical fiber to a hand-held probe. Patients scheduled for open resection for liver tumors were considered for inclusion. Multiple DRS measurements were performed on the liver surface after mobilization.

Results

In total, 1210 DRS spectra originated from 38 patients, were analyzed. When applying the data to an analytical model the volumetric absorption ratio factor of fat and water specified an explicit distinction between mild to moderate, and moderate to severe steatosis (p < 0.001). There were significant differences between none-to-mild and moderate-to-severe steatosis grade for the following parameters: reduced scattering coefficient (p < 0.001), Mie to total scattering fraction (p < 0.001), Mie slope (p = 0.003), lipid/(lipid + water) (p < 0.001), blood volume (p = 0.044) and bile volume (p < 0.001).

Conclusion

This study shows that it is possible to evaluate steatosis grades with hepatic surface diffuse reflectance spectroscopy measurements.  相似文献

Background

Whether there are sex differences in the outcome of patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) remains controversial. We undertook this study to assess whether there are sex-related differences in the long-term mortality in a large series of patients with CAD after PCI.

Methods

The study included 18,334 patients (4735 women and 13,599 men) with CAD treated with PCI. Propensity matching was performed to obtain a group of patients (3000 women and 3000 men) matched for all characteristics available in database. The primary outcome was a composite of cardiac mortality, myocardial infarction or stroke at 3?years of follow-up.

Results

The primary outcome occurred in 660 women and 1440 men (Kaplan-Meier [KM] estimates, 15.2% in women and 11.6% in men, unadjusted hazard ratio [HR]?=?1.35, 95% confidence interval [CI] 1.24 to 1.49; P?<?0.001). Women were at higher risk of all-cause mortality (15.4% vs. 12.3%; P?<?0.001), cardiac mortality (10.2% vs. 7.6%; P?<?0.001) and stroke (2.6% vs. 1.4%; P?<?0.001) than men. In matched patients, the primary outcome occurred in 371 women and 322 men (KM estimates, 13.4% vs. 11.6%, HR?=?1.18 [1.01–1.36], P?=?0.033). Women were at higher risk of myocardial infarction (4.2% vs. 3.1%; P?=?0.044) but not cardiac (8.7% vs. 8.2%; P?=?0.306) or all-cause death (12.5% vs. 12.9%; P?=?0.991) or stroke (1.9% vs. 1.6%; P?=?0.550) than men.

Conclusions

After propensity matching, women remained at a higher risk of a composite of cardiac mortality, myocardial infarction or stroke up to 3?years after PCI than men.  相似文献
