Background
Although guidelines have recommended that patients with chronic thromboembolic pulmonary hypertension (CTEPH) should be managed by a multidisciplinary team (MDT), there is a lack of clinical data indicating that the MDT improves CTEPH management.Objectives
The study aimed to identify the effect of an MDT on CTEPH management.Methods
We divided the study period into pre-MDT and post-MDT eras and compared the implementation rates of major diagnostic and therapeutic procedures.Results
Of 116 patients with CTEPH, 42 (36.2%) were diagnosed in the post-MDT era. The implementation rates of right heart catheterization (10.8% vs. 97.6%, p < 0.001) and pulmonary endarterectomy (32.4% vs. 59.5%, p < 0.005) were significantly increased in the post-MDT era. Balloon pulmonary angioplasty was not performed in the pre-MDT era but was performed in the post-MDT era.Conclusions
The MDT appears to be associated with improved CTEPH management. 相似文献2.
Background
There is a deleterious association between sedentary behavior and mortality risk factors. Elevated sedentary time has been reported in several studies that involved cardiac rehabilitation (CR) participants.Objectives
To examine the changes in sedentary behavior, breaks in sedentary time, and physical activity (PA) in CR participants.Methods
This was a prospective repeated measures study. Sedentary behavior and PA were assessed using accelerometer at baseline, 12 weeks, and 6 months after CR entry.Results
At 12 weeks, participants (n?=?58) spent more time in moderate-vigorous PA (MVPA) and tended to be less sedentary. However, the changes were lost by 6 month follow-up. Although the majority of participants met the recommended MVPA, our participants demonstrated elevated sedentary time. We found a strong positive correlation between time in light PA and number of breaks in sedentary time; neither of which showed any changes over time.Conclusions
By promoting MVPA as their main target, current CR programs may have little impact on changing the elevated sedentary behavior of their participants. Further, interrupting sedentary time with light PA could be an achievable strategy to reduce sedentary behavior in CR participants. 相似文献3.

Background
Ventilator hyperinflation (VHI) is effective in improving respiratory mechanics, secretion removal, and gas exchange in mechanically ventilated subjects; however, there are no recommendations for the best ventilator settings to perform the technique.Objective
To compare six modes of VHI, concerning physiological markers of efficacy and safety criteria to support the selection of optimal settings.Methods
Thirty mechanically ventilated patients underwent six modes of VHI in a randomized order. The delivered volume, expiratory flow bias criteria, overdistension, patient–ventilator asynchronies and hemodynamic variables were assessed during the interventions.Results
Volume-controlled ventilation with inspiratory flow of 20 lpm (VC-CMV20) and pressure support ventilation (PSV) achieved the best effectiveness scores (P?<?0.05). The target peak pressure of 40 cmH2O was associated with a high incidence of overdistension. PSV showed a lower incidence of patient–ventilator asynchronies.Conclusions
The modes VC-CMV20 and PSV are the most effective for VHI. Alveolar overdistension and patient–ventilator asynchronies must be considered when applying VHI. 相似文献4.

Background
The optimal timing of tracheotomy in critically ill ventilated patients remains controversial.Objectives
The objective of this meta-analysis was to assess tracheotomy timing for critically ill ventilated patients and determine the outcomes’ reliability.Methods
We searched PubMed, Embase, and the Cochrane Library for randomized controlled trials.Results
Compared with late tracheotomy, early tracheotomy presented a lower incidence of ventilator-associated pneumonia (VAP), shorter duration of mechanical ventilation (MV), and shorter intensive care unit (ICU) stay. However, trial sequential analysis (TSA), a kind of cumulative meta-analysis, indicated that the evidence was unreliable and inconclusive.Conclusions
The Findings suggest that early tracheotomy seems to be associated with a lower incidence of VAP, shorter duration of MV, shorter duration of sedation, and shorter ICU stay. However, the apparent benefits revealed in traditional meta-analysis contrast with the post-TSA results. More fully powered, randomized controlled trials focused on the outcomes of tracheotomy are highly warranted. 相似文献5.

Background
Cardiac rehabilitation (CR) has been shown to provide the best social, psychological and physical conditions for patient recovery after myocardial infarction (MI).Objectives
The aim of present study was to quantify the efficacy of exercise-based CR treatments in terms of relief from symptoms of anxiety and depression symptoms among patients with MI.Methods
Literature published up to August 2017 was reviewed systematically using relevant keywords, MeSH terms, and Emtree headings to search PubMed, Embase, CINAHL (Ebsco), Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science. The results of included studies were compared meta-analytically.Results
We found that exercise-based CR had a significant effect on decreasing anxiety and depression scores. Furthermore, exercise-based CR may alleviate anxiety and depressive symptoms at different time periods.Conclusions
For patients with MI, exercise-based CR has been demonstrated to alleviate anxiety and depressive symptoms. These findings highlight CR as essential and beneficial for minimizing MI patient anxiety and depression during recovery. 相似文献6.

Background
Cheyne-Stokes respiration and periodic breathing (CSRPB) have not been studied sufficiently in the intensive care unit setting (ICU).Objectives
To determine whether CSRPB is associated with adverse outcomes in ICU patients.Methods
The ICU group was divided into quartiles by CSRPB (86 patients in quartile 1 had the least CSRPB and 85 patients in quartile 4 had the most CSRPB). Adverse outcomes (emergent intubation, cardiorespiratory arrest, inpatient mortality and the composite of all) were compared between patients with most CSRPB (quartile 4) and those with least CSRPB (quartile 1).Results
ICU patients in quartile 4 had a higher proportion of cardiorespiratory arrests (5% versus 0%, (p=.042), and more adverse events over all (19% versus 8%, p=.041) as compared to patients in quartile 1.Conclusions
CSRPB can be measured in the ICU and it's severity is associated with adverse outcomes in critically ill patients. 相似文献7.

Background
Tumor necrosis factor receptor type 1-associated death domain protein (TRADD) mediates programmed cell death signaling as well as the Fas-induced cell death pathway. The downregulation of TRADD is found to be associated with the occurrence of many cancers. The present study was designed to investigate the association between TRADD and clinicopathologic features as well as its clinical significance in acute myeloid leukemia (AML).Methods
Real-time polymerase chain reaction was performed in 100 new AML, 23 AML complete remission patients, and 20 normal individuals. All statistical analysis was performed using SPSS software.Results
It was found that the expression of TRADD messenger RNA was lower in new AML patients as compared to healthy individuals and complete remission patients (P?=?0.00239). Moreover, TRADD messenger RNA levels were associated with clinical factors such as risk classification (P?=?0.0023) and complete remission (P?=?0.0147). Kaplan–Meier analysis revealed that the AML patients with high TRADD expression had significantly prolonged overall survival and higher complete remission compared with low TRADD expressing patients.Conclusions
It is concluded that downregulation of TRADD may be an independent potential prognostic biomarker in AML. 相似文献8.

Background
Kounis syndrome is a systemic complication following an allergic reaction, presenting with coronary artery spasm or thrombosis and occasionally with stent thrombosis that can have fatal outcome.Objectives
Heparins can induce allergic reactions via tissue antigenicity, heparin induced thrombocytopenia and contact system-activating effects of contaminants but allergy bivalirudin has not been reported so far.Methods
Herein, we describe a patient with fatal acute coronary in-stent thrombosis following an allergic reaction soon after an intra-arterial heparin dose and intravenous administration of bivalirudin during angioplasty.Results
The patient received intense myocardial infarction protocol treatment including angioplasty and defibillation together with antiallergic therapy but despite all of these efforts and measures, he succumbed 2 h later.Conclusions
Significant suspicion should be raised that life saving drugs such as heparin and bivalirudin could join forces with concurrent medication acting as antigens and induce fulminant and fatal stent thrombosis as a manifestation of Kounis syndrome 相似文献10.

Background
This study aimed to investigate the correlation between pancreatic stellate cell activation, matrix metallopeptidase 2 (MMP2) expression and lymph node metastasis in pancreatic carcinoma.Methods
Alpha-smooth muscle actin (ACTA2), Desmin (DES) and MMP2 were detected in 40 pancreatic carcinoma patients and 10 cases of normal pancreas tissues using immunohistochemistry. Then MMP2 and ACTA2 expression profiles in pancreatic cancer were obtained from UCSC (University of California, Santa Cruz) and SurvExpress.Results
A total of 67.5% and 55.0% of cases positively expressed ACTA2 and DES in pancreatic carcinoma, respectively. MMP2 in pancreatic carcinoma was expressed in 55.0% of cases, and there were significant differences between the lymph node metastasis group and the lymph node nonmetastasis group, as well as invasion and noninvasion to the peripheral tissue group (P < 0.01). High throughput sequencing databases verified that ACTA2 and MMP2 gene expression were both upregulated in pancreatic carcinoma tissues.Conclusions
The coexpression of ACTA2 and DES was related to the expression of MMP2, and positively correlated with lymph node metastasis. Activation of pancreatic stellate cells may promote the expression of MMP2 and enhance the invasion and metastasis of pancreatic carcinoma. 相似文献11.

Introduction
Clostridium difficile is the leading cause of health care–associated gastric illness. Environmental contamination with C difficile spores is a risk factor for contact transmission, and toilet flushing causes such contamination. This work explores toilet contamination persistence and environmental contamination produced over a series of flushes after contamination.Methods
A flushometer toilet was seeded with C difficile spores in a sealed chamber. The toilet was flushed 24times, with postflush bowl water samples and settle plates periodically collected for culturing and counting. Air samples were collected after each of 12 flushes using rotating plate impactors.Results
Spores were present in bowl water even after 24 flushes. Large droplet spore deposition accumulated over the 24-flush period. Droplet nuclei spore bioaerosol was produced over at least 12 flushes.Conclusions
Toilets contaminated with C difficile spores are a persistent source of environmental contamination over an extended number of flushes. 相似文献12.

Background
Sarcopenia is a well-recognized geriatric syndrome. We sought to determine the prevalence of sarcopenia and factors associated with it among community-dwelling older adults in Taiwan.Methods
A cross-sectional study was conducted in Yuanshan Township, Yilan County, Taiwan. Data of 731 community-dwelling adults aged 65 and older were evaluated. Demographic characteristics, anthropometry, medical history, biochemistry results, and dual-energy X-ray absorptiometry results were collected for analysis.Results
Males had a higher rate of sarcopenia than did females and had lower values for body weight, body mass index, waist circumference, percentage of body fat, and lean body mass. Poor nutritional status as determined by the Mini Nutritional Assessment correlated positively with markers for sarcopenia. Levels of vitamin D and folic acid correlated positively with some sarcopenia markers.Conclusions
Gender differences and nutritional factors may influence the development of sarcopenia. Vitamin D is positively correlated with relative appendicular skeletal muscle mass in males with sarcopenia, and folic acid was positively correlated with gait speed in females with sarcopenia. 相似文献13.

Background
Left ventricular assist devices (LVADs) improve quality of life in end-stage heart failure but can cause serious complications such as infections with driveline infection causing significant morbidity and mortality.Objectives
The purpose of this systematic literature review is to synthesize the literature to determine variables associated with driveline infection and seek opportunities to improve nursing management of LVAD drivelines.Methods
A systematic literature review was performed. The evidence was synthesized using the Johns Hopkins Nursing Evidence-Based Practice tools and the Chain of Infection epidemiological framework.Results
Thirty-four studies focused on vulnerable host, portal of entry, and causative organism aspects of the Chain of Infection. Increased BMI, younger age, exposed driveline velour showed increased risk of infection and driveline dressing protocol change showed lower risk of infection.Conclusions
Although some risk factors for infection were identified, evidence is still limited. Nurses are uniquely positioned to improve driveline management, disrupting the chain of infection. 相似文献14.

Background
Liver transplant is a potential cure for liver failure and hepatic malignancy but there are many techniques which have been described for vascular reconstruction. This study was to compare the prevalence of non-anastomotic biliary stricture and other surgical complications based on Clavien-Dindo scoring system, in initial portal reperfusion (sequential) versus simultaneous or initial artery reperfusion.Data sources
Meta-analysis of published studies comparing the outcomes of both techniques was carried out. Data search was conducted across the major databases and studies were selected under the guidance of the Cochrane guidelines for systematic reviews and meta-analysis.Results
Seven studies were included to address the primary and the secondary outcomes. No statistical difference was found in the incidence of non-anastomotic biliary strictures (OR?=?0.40; P?=?0.14), regardless of reperfusion technique. The pooled estimate of the Clavien-Dindo grading of complications was not significantly different between the techniques, though Clavien-Dindo II complications were higher in the simultaneous or initial artery reperfusion group than the initial portal reperfusion group (OR?=?2.73; P?=?0.01). Similarly, there was no difference in the operative time, hospital stay and other outcomes addressed in this report.Conclusions
The available evidence suggests that there is no significant difference demonstrated in the rate of non-anastomotic biliary strictures or other complications, between the two techniques, except for Clavien-Dindo II complications. 相似文献15.

Background
Hepatocellular carcinoma is the most common innate liver tumor. Due to improved surgical techniques, even extended resections are feasible, and more patients can be treated with curative intent. As the liver is the central metabolic organ, preoperative metabolic assessment is crucial for risk stratification. Sarcopenia, obesity and sarcopenic obesity characterize body composition and metabolic status. Here we present the impact of body composition on survival after liver resection in patients with hepatocellular carcinoma.Methods
A retrospective database analysis of 70 patients who were assigned for liver resection due to hepatocellular carcinoma was conducted. For assessment of sarcopenia and obesity, skeletal muscle surface area was measured at lumbar vertebra 3 level (L3) in preoperative four-phase contrast enhanced abdominal CT scans, and L3 muscle index and body fat percentage were calculated.Results
Univariate analysis comparing the survival curves using the score test demonstrated superior postoperative overall survival for sarcopenic (P?=?0.035) and sarcopenic obese (P?=?0.048) patients as well as a trend favoring obese (P?=?0.130) subjects. Whereas multivariate analysis could not identify significant difference in postoperative survival regarding sarcopenia, obesity or sarcopenic obesity. Only large tumor size, multifocal disease and male gender were risk factors for long-term survival.Conclusions
Sarcopenia, obesity and sarcopenic obesity are indeed no risk factors for poor postoperative survival in this study. Our data do not support the evaluation of sarcopenia, obesity and sarcopenic obesity before liver resection in hepatocellular carcinoma patients. 相似文献16.

Background
The Stanford integrated psychosocial assessment for transplantation (SIPAT) is a validated psychosocial evaluation tool in the transplant population.Objective
We evaluated SIPAT in predicting post-left ventricular assist device (LVAD) outcomes, including cumulative re-admissions, driveline infections, pump malfunction, pump thrombosis, gastrointestinal bleeding, major bleeding, stroke and right ventricular failure.Methods
This retrospective study included 50 LVAD patients at an academic institution in the United States who had a pre-implant SIPAT score during the years 2015-2017. Patients were split into two groups based on SIPAT score, separating a “excellent”/“good” from a “minimally acceptable”/“poor” candidate. Poisson regression, using SIPAT as both a categorical and continuous variable, was used to compare the incidence rates of the primary outcome of cumulative re-admissions and secondary outcomes of LVAD complications.Results
The patient cohort was predominantly male 93.5% vs 89.4% (p = 0.629) with a median age of 67.0 vs 58.0 years (p = 0.037), planned destination therapy 48.4% vs 68.4% (p = 0.242) and median LVAD follow-up time of 241 vs 379 days (p = 0.10) in the low- and high- SIPAT groups, respectively. SIPAT was not a significant predictor for cumulative re-admissions, but there was an association between higher SIPAT scores and major bleeding.Conclusion
In this single-center retrospective study, SIPAT did not predict cumulative re-admissions. Further study is required to validate SIPAT before clinical implementation. 相似文献17.

Objectives
To identify risk factors for mortality in a cohort of carbapenem-resistant enterobacteriaceae (CRE) carriers, focusing on immunosuppression and other risk factors known at the time of CRE carriage detection.Methods
We prospectively followed all new and known CRE carriers admitted between June 2016 and June 2017 to a single tertiary center in Israel. Patients were included in the study after confirmation of the carrier state. Demographic and clinical data were documented on admission or CRE acquisition and patients were followed prospectively post-discharge until January 2018 or death. Risk factors for mortality known at the time of the first encounter with a CRE carrier were sought. Adjusted hazard ratios (HR) for mortality at end of follow-up with 95% confidence intervals (CI) were assessed using Cox regression analysis.Results
A total of 115 patients were included in the analysis. During the study period, 66 (57.4%) patients died. Immunosuppression was associated with mortality (HR 1.95, CI 95% 1.12–3.44), adjusted to the Charlson co-morbidity score, functional status, chronic renal disease and Klebsiella pneumonia CRE, the latter three also significantly associated with mortality. CRE bacteremia occurred among 24 (20.9%) carriers during follow up, more frequently among immunosuppressed patients and was significantly associated with mortality at end of follow-up (p?=?0.015).Conclusion
Immunosuppression is independently associated with mortality among CRE carriers, possibly related to CRE bacteremia that is frequent among these patients. Further research is needed on interventions to prevent deaths among CRE carriers. 相似文献18.
Background
Postoperative cognitive dysfunction (POCD) is a very common postoperative complication occurring mainly after high-risk surgery, especially in the elderly individuals. This study aimed to investigate potential risk factors for POCD in elderly patients after total joint arthroplasty (TJA).Materials and Methods
A total of 257 eligible elderly patients (≥65 years) who were scheduled for elective TJA for osteoarthritis with general anesthesia were enrolled. An experienced psychiatrist was invited to evaluate the cognitive function at baseline (1 day before the surgery) and at day 7 after the surgery. Univariate and multiple logistic regression analyses were performed to screen risk factors associated with POCD. Receiver-operating characteristic curve analysis was performed to assess the predictive value of serum 25-hydroxyvitamin D [25(OH)D] expression for POCD.Results
Of all the 257 enrolled patients, 55 (21.4%) developed POCD within 7 days after the surgery. Serum 25(OH)D level was the only independent risk factor associated with POCD (odds ratio: 1.77, 95% confidence interval: 1.13-2.78, P?=?0.016) by multiple logistic regression analysis. The area under the curve of 25(OH)D for POCD was 0.687, with the cut-off value of 11.2 ng/mL, sensitivity of 41.82% and specificity of 78.71% respectively (95% confidence interval: 0.617-0.757, P < 0.001).Conclusions
Our results revealed that preoperative serum 25(OH)D level was an independent risk factor for POCD in elderly subjects after TJA. 相似文献19.

Background
Employee satisfaction is thought to impact performance. However, which aspects of employee satisfaction matter most is unknown. We utilized data from the Veterans Affairs Medical Centers(VAMC) via their Strategic Analytics for Improvement and Learning program to examine the association between organizational satisfaction as well as job-specific satisfaction with measures of patient safety, patient satisfaction, and hospital rating.Methods
The correlation between employee satisfaction with their organization and with their specific job were examined across indicators of patient care using Pearson and Spearman's correlation. Employee satisfaction data were obtained from the All Employee Survey.Results
We found that employee job-specific satisfaction does not correlate with patient outcomes, whereas higher satisfaction with the organization is associated with improved patient safety (ρ?=??0.19, P < .05) and correlates with all aspects of patient satisfaction (“top box” ratings of hospital [r?=?0.30, P < 0.005], primary care [r?=?0.25, P < 0.005], and specialty care [r?=?0.14, P < 0.005]). Further, employees are more satisfied with their job and organization when they work at a VAMC with a higher Star rating.Conclusion
Employee organizational satisfaction and job-specific satisfaction are distinct metrics, and it is higher organizational satisfaction that is associated with improved patient care. 相似文献20.
