Background

Nodal positivity is a predictor of poor survival following resection for intrahepatic cholangiocarcinoma (ICC). The aim of this study was to evaluate the impact of surgical resection on survival in patients with lymph node (LN) positive ICC.

Methods

An augmented version of the Surveillance, Epidemiology, and End Results program database was utilized to identify patients with LN-positive ICC without distant metastases from 2000 to 2014. Patients were stratified by treatment: chemotherapy alone or surgical resection with/without chemotherapy. Survival was evaluated using Kaplan–Meier and Cox proportional hazard models.

Results

169 patients who underwent treatment for LN-positive ICC were identified. 88% underwent surgical resection and 12% underwent chemotherapy alone. The median survival for patients who underwent surgical resection was not different from patients treated with chemotherapy alone (19 months 95% Confidence Interval (CI) 17–33 versus 20 months CI 10–27, p = 0.323). A cox-proportional hazard ratio model demonstrated that black race was associated with worse survival (p < 0.05), while surgical resection was not independently associated with survival.

Conclusion

Surgical resection for patients with LN-positive ICC may not improve survival compared to chemotherapy alone. Pathologic LN evaluation should be performed prior to surgical resection, to improve patient selection and ensure receipt of optimal therapy.  相似文献

Background

Portal lymphadenectomy for intrahepatic cholangiocarcinoma (ICC) is encouraged for staging purposes, though it is under-utilized for clinically early-stage tumors. We sought to determine if any factor knowable prior to resection influences rates of portal lymph node metastases.

Methods

The Surveillance, Epidemiology, and End Results (SEER) Program (1973–2014) database was queried to identify patients with T1/T2 ICC undergoing resection. Patients were stratified by lymph node (LN) status. Patients deemed LN negative required examination of six or more LNs (AJCC guidelines).

Results

One-hundred and fifty-two patients were included in the analysis (LN negative: 38, LN positive: 114). Patients with LN negative cancers experienced prolonged overall survival as compared to patients with positive LNs (median 77 months vs 19 months, respectively p < 0.001). Twelve patients had well-differentiated tumors (G1), 92 patients had moderately-differentiated tumors (G2) and 58 patients had poorly-differentiated tumors (G3). Tumor grade (OR 3.9, CI 1.1–13.7, p = 0.031) and male sex (OR 2.6, CI 1.1–6.1, p = 0.022) were associated with positive LNs on multivariable logistic regression analysis.

Conclusion

Intermediate/High grade and male sex are associated with high rates of lymph node metastasis for patients with early-stage ICC, which portends abbreviated overall survival.  相似文献

Background

Few studies have investigated the outcome of pancreatectomy associated with artery resection (PAR).

Methods

Retrospective analysis of a cohort of operated borderline or locally advanced pancreatic cancer patients with surgically confirmed arterial involvement. Short and long-term outcome were analyzed and compared in patients who underwent PAR (Group 1) and palliative surgery (Group 2).

Results

Of 73 patients who underwent surgical exploration with intent of resection, 34 underwent PAR (±venous resection) (Group 1) and 39 underwent palliation (Group 2). 23 patients (67.7%) in Group 1 underwent combined artery-vein resection (AVR). Operation time was longer and blood loss higher in group 1 compared to group 2. There were no differences in post-operative mortality (2.9% vs 2.6%, p = 0.9) and post-operative surgical complications (38.2% vs 25.6%, p = 0.2). The 1, 3 and 5 years survival in Group 1 was superior to Group 2 (63.7%, 23.4% and Q3 23.4% vs 41.7%, 3.2% and 0, p = 0.003).

Conclusion

PAR seems to be safe and feasible in well selected patients and associated with an advantage of survival compared to palliation, in patients affected by locally advanced pancreatic cancer.  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

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

Centralization of pancreatic resections is advocated due to a volume-outcome association. Pancreatic surgery is in Norway currently performed only in five teaching hospitals. The aim was to describe the short-term outcomes after pancreatoduodenectomy (PD) within the current organizational model and to assess for regional disparities.

Methods

All patients who underwent PD in Norway between 2012 and 2016 were identified. Mortality (90 days) and relaparotomy (30 days) were assessed for predictors including demographic data and multi-visceral or vascular resection. Aggregated length-of-stay and national and regional incidences of the procedure were also analysed.

Results

A total of 930 patients underwent PD during the study period. In-hospital mortality occurred in 20 patients (2%) and 34 patients (4%) died within 90 days. Male gender, age, multi-visceral resection and relaparotomy were independent predictors of 90-day mortality. Some 131 patients (14%) had a relaparotomy, with male gender and multi-visceral resection as independent predictors. There was no difference between regions in procedure incidence or 90-day mortality. There was a disparity within the regions in the use of vascular resection (p = 0.021).

Conclusion

The short-term outcomes after PD in Norway are acceptable and the 90-day mortality rate is low. The outcomes may reflect centralization of pancreatic surgery.  相似文献

Background

Best practise care optimises survival and quality of life in patients with pancreatic cancer (PC), but there is evidence of variability in management and suboptimal care for some patients. Monitoring practise is necessary to underpin improvement initiatives. We aimed to develop a core set of quality indicators that measure quality of care across the disease trajectory.

Methods

A modified, three-round Delphi survey was performed among experts with wide experience in PC care across three states in Australia. A total of 107 potential quality indicators were identified from the literature and divided into five areas: diagnosis and staging, surgery, other treatment, patient management and outcomes. A further six indicators were added by the panel, increasing potential quality indicators to 113. Rated on a scale of 1–9, indicators with high median importance and feasibility (score 7–9) and low disagreement (<1) were considered in the candidate set.

Results

From 113 potential quality indicators, 34 indicators met the inclusion criteria and 27 (7 diagnosis and staging, 5 surgical, 4 other treatment, 5 patient management, 6 outcome) were included in the final set.

Conclusions

The developed indicator set can be applied as a tool for internal quality improvement, comparative quality reporting, public reporting and research in PC care.  相似文献

Background

Gallstones and alcohol are currently the most frequent aetiologies of acute pancreatitis (AP). The aim of this study is to quantify these aetiologies worldwide, by geographic region and by diagnostic method.

Methods

A systematic review of observational studies published from January 2006 to October 2017 was performed. The studies provided objective criteria for establishing the diagnosis and aetiology of AP for at least biliary and alcoholic causes. A random-effects meta-analysis was used to assess the frequency of biliary (ABP), alcoholic (AAP) and idiopathic AP (IAP) worldwide and to perform 6 subgroup analyses: 2 compared diagnostic methods for AP aetiology and the other 4 compared geographic regions.

Results

Forty-six studies representing 2,341,007 patients of AP in 36 countries were included. The global estimate of proportion (95% CI) of aetiologies was 42 (39–44)% for ABP, 21 (17–25)% for AAP and 18 (15–22)% for IAP. In studies that used discharge code diagnoses and in those from the US, IAP was the most frequent aetiology. ABP was more frequent in Latin America than in other regions.

Conclusion

Gallstones represent the main aetiology of AP globally, and this aetiology is twice as frequent as the second most common aetiology.  相似文献

Objectives

The authors investigated 1-year outcomes after transcaval access and closure for transcatheter aortic valve replacement (TAVR), using commercially available nitinol cardiac occluders off-label.

Background

Transcaval access is a fully percutaneous nonfemoral artery route for TAVR. The intermediate-term fate of transcaval access tracts is not known.

Methods

The authors performed a prospective, multicenter, independently adjudicated trial of transcaval access, using Amplatzer nitinol cardiac occluders (Abbott Vascular, Minneapolis, Minnesota), among subjects without traditional transthoracic (transapical or transaortic) access options. One-year clinical follow-up included core laboratory analysis of serial abdominal computed tomography (CT).

Results

100 subjects were enrolled. Twelve-month mortality was 29%. After discharge, there were no vascular complications of transcaval access. Among 83 evaluable CT scans after 12 months, 77 of fistulas (93%) were proven occluded, and only 1 was proven patent. Fistula patency was not associated with overall survival (p = 0.37), nor with heart failure admissions (15% if patent vs. 23% if occluded; p = 0.30). There were no cases of occluder fracture or migration or visceral injury.

Conclusions

Results are reassuring 1 year after transcaval TAVR and closure using permeable nitinol occluders off-label. There were no late major vascular complications. CT demonstrated spontaneous closure of almost all fistulas. Results may be different in a lower-risk cohort, with increased operator experience, and using a dedicated transcaval closure device.

Background and aim

Metabolic syndromes are prevalent worldwide and result in various complications including obesity, cardiovascular disease and type II diabetes. Betulinic acid (BA) is a naturally occurring triterpenoid that has anti-inflammatory properties. We hypothesized that treatment with BA may result in decreased body weight gain, adiposity and hepatic steatosis in a diet-induced mouse model of obesity.

Methods and results

Mice fed a high-fat diet and treated with BA showed less weight gain and tissue adiposity without any change in calorie intake. Gene expression profiling of mouse tissues and cell lines revealed that BA treatment increased expression of lipid oxidative genes and decreased that of lipogenesis-related genes. This modulation was mediated by increased AMP-activated protein kinase (AMPK) phosphorylation, which facilitates energy expenditure, lipid oxidation and thermogenic capacity and exerts protective effects against obesity and nonalcoholic fatty liver disease. Overall, BA markedly inhibited the development of obesity and nonalcoholic fatty liver disease in mice fed a high-fat diet, and AMPK activation in various tissues and enhanced thermogenesis are two possible mechanisms underlying the antiobesity and antisteatogenic effects of BA.

Conclusions

The current findings suggest that treatment with BA is a potential dietary strategy for preventing obesity and nonalcoholic fatty liver disease.  相似文献

Objectives

The goal of this study was to investigate the trends, predictors, and outcomes of delayed discharge (>72 h) after transcatheter aortic valve replacement.

Background

Length of stay post–transcatheter aortic valve replacement may have significant clinical and administrative implications.

Methods

Data from the Transcatheter Valve Therapy Registry were used to identify patients undergoing nonaborted transfemoral transcatheter aortic valve replacement who survived to discharge, and data linked from the Centers for Medicare & Medicaid Services were used to provide 1-year events. Patients were categorized to early discharge (≤72 h) versus delayed discharge (>72 h). The trends, predictors, and adjusted 1-year outcomes were compared in both groups.

Results

From 2011 to 2015, a total of 13,389 patients (55.1%) were discharged within 72 h, whereas 10,896 patients (44.9%) were discharged beyond 72 h. There was a significant decline in rates of delayed discharge across the study period (62% vs. 34%; p < 0.01). This remained unchanged when stratified by Transcatheter Valve Therapy risk scores. Several factors were identified as independent predictors of early and delayed discharge. After adjustment for in-hospital complications, delayed discharge was an independent predictor of 1-year all-cause mortality (hazard ratio: 1.45; 95% confidence interval: 1.30 to 1.60; p < 0.01).

Conclusions

Rates of delayed discharge have declined from 2011 to 2015. Delayed discharge is associated with a significant increase in mortality even after adjusting for in-hospital complications. Further work is necessary to determine if predictors of early discharge could be used to develop length of stay scores that might be instrumental in administrative, financial, or clinical policy development.  相似文献

Background

Patients with mitral stenosis and atrial fibrillation (AF) require anticoagulation for stroke prevention. Thus far, all studies on direct oral anticoagulants (DOACs) have excluded patients with moderate to severe mitral stenosis.

Objectives

The aim of this study was to validate the efficacy of DOACs in patients with mitral stenosis.

Methods

The study population was enrolled from the Health Insurance Review and Assessment Service (HIRA) database in the Republic of Korea, and it included patients who were diagnosed with mitral stenosis and AF and either were prescribed DOACs for off-label use or received conventional treatment with warfarin. The primary efficacy endpoint was ischemic strokes or systemic embolisms, and the safety outcome was intracranial hemorrhage.

Results

A total of 2,230 patients (mean age 69.7 ± 10.5 years; 682 [30.6%] males) were included in the present study. Thromboembolic events occurred at a rate of 2.22%/year in the DOAC group, and 4.19%/year in the warfarin group (adjusted hazard ratio for DOAC: 0.28; 95% confidence interval: 0.18 to 0.45). Intracranial hemorrhage occurred in 0.49% of the DOAC group and 0.93% of the warfarin group (adjusted hazard ratio for DOAC: 0.53; 95% confidence interval: 0.22 to 1.26).

Conclusions

In patients with AF accompanied with mitral stenosis, DOAC use is promising and hypothesis generating in preventing thromboembolism. Our results need to be replicated in a randomized trial.  相似文献

Background

Pulmonary Tuberculosis (PTB) is a contagious, airborne infection that destroys when M. tuberculosis primarily attacks the lungs. PTB is curable with an early diagnosis and antibiotic treatment. Stigmatization and negative emotions resulting from the illness could result in long term impairment of patients psychological well being which may result in work absenteeism resulting in loss of productivity and reduced monthly income.

Methods

This was a prospective study which was conducted over a period of one and half year. A total of 198 patients were recruited for the study. Quality Of Life (QOL) was assessed at baseline and at the end of intensive phase. For QOL WHO based QOLBREF was used.

Results

In the present study patients scored lowest in the baseline physical (8.36 ± 1.60) followed by the psychological domain (10.40 ± 1.72) however at the end of intensive phase both physical (11.98 ± 1.70) and psychological (12.75 ± 1.) domains improved very much and the difference was statistically significant.

Conclusion

We conclude that HRQOL is significantly reduced in patients with PTB, and that it improves rapidly and significantly with DOTS-based intensive phase of treatment. Special focus on reduction of stigmatization should be given in the management of TB to reduce the psychological distress.  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

Background

There have been only a few reports that describe the long-term outcomes of Subtotal cholecystectomy (SC).

Methods

A total of 59 patients underwent “reconstituting” SC at our hospital between January 2005 and July 2017. In the 59 patients, risk factors for long-term complications were analyzed. In addition, in the patients with acute cholecystitis (AC), perioperative and long-term clinical factors were compared for patients who underwent SC (n = 48) and those who underwent total cholecystectomy (n = 378).

Results

In the 59 patients who underwent SC, long-term complication developed in 14 (23.7%), including residual calculus in the common bile duct (n = 12), remnant cholecystitis (n = 1), and persistent severe inflammatory response (n = 1). Postoperative magnetic resonance image was performed in 35/59 patients (59.3%) who underwent SC. In these 35 patients, the size of the remnant gallbladder calculated by magnetic resonance cholangiopancreatography was significantly associated with the occurrence of long-term complications (p = 0.009). In the patients with AC, regarding long-term complications, the incidence of residual calculus in the common bile duct (16.6 versus 0.7%) was significantly higher in the SC group.

Conclusions

SC was associated with a relatively high incidence of long-term complications associated with remnant calculus.  相似文献

Objectives

The authors sought to define the feasibility and performance of 3-dimensional (3D) vena contracta area (VCA) measurement in evaluating total residual mitral regurgitation (MR) following percutaneous edge-to-edge clip (E-EC) mitral valve repair.

Background

Residual MR severity after percutaneous repair is not only a determinant of procedural success, but also a major prognostic factor. To date, no single echocardiographic method has been recommended for post-procedural MR quantification, with the evaluation currently relying on a complex, multiparametric appraisal.

Method

The authors performed a retrospective study of patients undergoing the E-EC procedure, for which baseline and post-repair 3D color Doppler transesophageal echocardiogram datasets were available. Total VCA was recorded as the sum of individual VCAs (if more than 1) and compared with an expert multiparametric appraisal of MR severity as the reference standard. Receiver-operating characteristic analysis was performed.

Results

155 patient studies were available for review. Total VCA correlated with hemodynamic parameters and was significantly reduced after E-EC. Receiver-operating characteristic analysis demonstrated a VCA threshold of 0.27 cm2 for identification of ≥moderate MR, with good diagnostic accuracy (area under the curve 0.81) and a negative predictive value of 92%. Smaller VCA was associated with clinical New York Heart Association functional class improvement at 30-day follow-up.

Conclusions

Measurement of VCA is feasible using 3D color Doppler transesophageal echocardiography and provides reliable quantification of MR following E-EC transcatheter mitral valve repair.  相似文献

Objectives

The aim of this study was to describe the costs of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and the association of complications during CTO PCI with costs and length of stay (LOS).

Background

CTO PCI generally requires more procedural resources and carries higher risk for complications than PCI of non-CTO vessels. The costs of CTO PCI using the hybrid approach have not been described, and no studies have examined the impact of complications on in-hospital costs and LOS in this population.

Methods

Costs were calculated for 964 patients in the 12-center OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry using prospectively collected resource utilization and billing data. Multivariate models were developed to estimate the incremental costs and LOS associated with complications. Attributable costs and LOS were calculated by multiplying the independent cost of each event by its frequency in the population.

Results

Mean costs for the index hospitalization were $17,048 ± 9,904; 14.5% of patients experienced at least 1 complication. Patients with complications had higher mean hospital costs (by $8,603) and LOS (by 1.5 days) than patients without complications. Seven complications were independently associated with increased costs and 6 with LOS; clinically significant perforation and myocardial infarction had the greatest attributable cost per patient. Overall, complications accounted for $911 per patient in hospital costs (5.3% of the total costs) and 0.2 days of additional LOS.

Conclusions

Complications have a significant impact on both LOS and in-hospital costs for patients undergoing CTO PCI. Methods to identify high-risk patients and develop strategies to prevent complications may reduce CTO PCI costs.  相似文献

Background

The Medicare Hospital Readmissions Reduction Program has led to fewer readmissions following hospitalizations with a principal diagnosis of heart failure (HF). Patients with HF are frequently hospitalized for other causes.

Objectives

This study sought to compare trends in Medicare risk-adjusted, 30-day readmissions following principal HF hospitalizations and other hospitalizations with HF.

Methods

This was a retrospective study of 12,973,853 Medicare hospitalizations with a principal or secondary diagnosis of HF between January 2008 and June 2015. Hospitalizations were categorized as follows: principal HF hospitalizations; principal acute myocardial infarction or pneumonia hospitalizations with secondary HF; and other hospitalizations with secondary HF. The study examined trends in risk-adjusted, 30-day, all-cause readmission rates for each cohort and trends in differences in readmission rates among cohorts by using linear spline regression models.

Results

Before passage of the Affordable Care Act in March 2010, risk-adjusted, 30-day readmission rates were stable for all 3 cohorts, with mean monthly rates of 26.1%, 24.9%, and 24.4%, respectively. Risk-adjusted readmission rates started declining after passage of the Affordable Care Act by 1.09% (95% confidence interval [CI]: 0.51% to 1.68%), 1.24% (95% CI: 0.92% to 1.57%), and 1.05% (95% CI: 0.52% to 1.58%) per year, respectively, until implementation of the Hospital Readmissions Reduction Program in October 2012 and then stabilized for all 3 cohorts.

Conclusions

Patients with HF are often hospitalized for other causes, and these hospitalizations have high readmission rates. Policy changes led to decreases in readmission rates for both principal and secondary HF hospitalizations. Readmission rates in both groups remain high, suggesting that initiatives targeting all hospitalized patients with HF continue to be warranted.  相似文献

Background

Lymph node metastasis (LNM)has widely been recognized as a poor prognostic indicator for hepatocellular carcinoma (HCC) patients. Preoperative prediction of LNM is important for clinicians to decide on treatment. This study was designed to develop a simple and convenient system to predict LNM.

Methods

Consecutive HCC patients who were suspected to have LNM were divided into a training, an internal validation and an external validation cohort. The receiver operating characteristic (ROC) analysis was used to determine the threshold value of the preoperative serological variables. A nomogram visualization system model was then established.

Result

Of the 287 patients, there were 31 patients who had LNM (10.8%), and 21 of 203 patients (10.3%) were in the training cohort and 10 of 84 patients (11.9%) in the internal validation cohort. Sixteen of 176 patients (9.1%) in the external validation cohort had LNM. The serological indices including neutrophil/lymphocyte rate, age, platelet, prothrombin time, and total protein, were included in the nomogram. The areas of the ROC curve were 0.846, 0.679 and 0.738 in predicting LNM in the training cohort, the internal validation cohort and the external validation cohort, respectively.

Conclusion

The scoring system constructed using the preoperative serological variables predicted LNM in HCC patients.  相似文献
