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2.

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3.

Objective
To assess periodontitis prevalence and severity in HIV infected patients as compared to controls. Furthermore, to assess whether HIV infection characteristics are associated with periodontitis.Design
cross-sectional controlled study.Methods
We assessed prevalence and severity of periodontitis in 258 HIV-infected patients and 539 historical controls with the Dutch Periodontal Screening Index (DPSI). HIV characteristics were collected from medical charts. Age-related diseases and oral care were assessed with questionnaires.Results
Severe periodontitis (DPSI 4) was more prevalent in HIV-infected patients than in controls (66% vs. 36%, p?=?0.002). HIV-infection, increasing age and male sex were significant risk factors for severe periodontitis. In particular, older male HIV patients have a higher risk of severe periodontitis. Clinical, immunological and virologic characteristics, and antiretroviral therapy were not associated with periodontitis prevalence or severity. HIV-infected patients rate the importance of their oral health as high, although many do not disclose their HIV infection to their dentists.Conclusions
Prevalence and severity of periodontitis are higher in HIV-infected patients compared to controls, particularly in older males. Awareness of the increased prevalence of periodontitis associated with HIV-infection among patients and health-care professionals could significantly improve oral health and quality of life of HIV-infected patients. 相似文献4.

Background
There is limited data suggesting that recovery from severe pulmonary infection with Coccidioides may be hastened by the addition of systemic corticosteroids.Methods
We present a case report of 2 patients with persistent and progressive coccidioidomycosis who demonstrated a dramatic response to adjunctive corticosteroid therapy.Results
Both patients had Coccidioides immitis cultured from respiratory samples. One was a 69-year-old man who had been treated with combination fluconazole and liposomal amphotericin for over 6 weeks, with persistent fever and pneumonia. The other was a 61-year-old man treated with fluconazole and then amphotericin for 3 weeks, with progression to acute respiratory distress syndrome and shock. Both received short courses of intravenous methylprednisolone and recovered to be discharged home.Conclusions
As opposed to associated hypersensitivity, corticosteroid treatment in these cases was directed at modulating the ongoing destructive effects of unchecked inflammation. Rapid improvement was noted in both cases and raises the possibility that the addition of systemic corticosteroids may hasten recovery in patients with severe coccidioidomycosis. 相似文献5.

Background
There are sparse data to support the recommendation for inferior vena cava (IVC) filters in patients with recurrent pulmonary embolism while on anticoagulant therapy.Methods
This was a retrospective cohort study of administrative data from the Premier Healthcare Database, 2009-2014. All-cause mortality according to the use of IVC filters was evaluated in patients who suffered a recurrent pulmonary embolism within 3 months of an index pulmonary embolism. Patients were identified by International Classification of Disease, 9th Clinical Modification codes. A time-dependent analysis controlled for immortal time bias.Results
An IVC filter was inserted in 603 of 814 (74.1%) of patients hospitalized for recurrent pulmonary embolism within 3 months of an index pulmonary embolism. Mortality with an IVC filter was 18 of 603 (3.0%) vs 83 of 211 (39.3%) (P < .0001) without a filter. Among patients with recurrent pulmonary embolism who were stable and did not receive thrombolytic therapy or undergo pulmonary embolectomy, mortality with an IVC filter was 15 of 572 (2.6%) vs 72 of 169 (42.6%) (P < .0001) without a filter.Conclusion
In the United States, usual practice was to insert an IVC filter in patients with early recurrent pulmonary embolism. Mortality was lower in those who received an IVC filter. Even stable patients with early recurrent pulmonary embolism showed a decreased mortality with IVC filters, even though in other circumstances, IVC filters do not reduce mortality in stable patients. Additional cohort studies would be useful in the absence of a randomized controlled trial. 相似文献6.

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
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9.

Listeriosis
is a foodborne illness that can result in septicaemia, Central Nervous System (CNS) disease, foetal loss and death in high risk patients.Objectives
To analyse the demographic trends, clinical features and treatment of non-perinatal listeriosis cases over a ten year period and identify mortality-associated risk factors.Methods
Reported laboratory-confirmed non-pregnancy associated cases of listeriosis between 2006 and 2015 in England were included and retrospectively analysed. Multivariate logistic regression analysis was performed to determine independent risk factors for mortality.Results
1357/1683 reported cases met the inclusion criteria. Overall all-cause mortality was 28.7%; however, mortality rates declined from 42.1% to 20.2%. Septicaemia was the most common presentation 69.5%, followed by CNS involvement 22.4%. CNS presentations were significantly associated with age?<?50 years, and septicaemia with older age. Age?>?80 years (OR 3.32 95% CI 1.92–5.74), solid-organ malignancy (OR 3.42 95% CI 2.29-5.11), cardiovascular disease (OR 3.30 95% CI 1.64–6.63), liver disease (OR 4.61 95% CI 2.47–8.61), immunosuppression (OR 2.12 95% CI 1.40-3.21) and septicaemia (OR 1.60 95% CI 1.17–2.20) were identified as independent mortality risk factors.Conclusions
High risk groups identified in this study should be the priority focus of future public health strategies aimed at reducing listeriosis incidence and mortality. 相似文献10.

Background
Recent guidelines have suggested avoiding beta-blockers in the setting of cocaine-associated acute coronary syndrome. However, the available evidence is both scarce and conflicted. The purpose of this systematic review and meta-analysis is to investigate the evidence pertaining to the use of beta-blockers in the setting of acute cocaine-related chest pain and its implication on clinical outcomes.Methods
Electronic databases were systematically searched to identify literature relevant to patients with cocaine-associated chest pain who were treated with or without beta-blockers. We examined the end-points of in-hospital all-cause mortality and myocardial infarction. Pooled risk ratios (RR) and their 95% confidence intervals (CI) were calculated for all outcomes using a random-effects model.Results
Five studies with a total of 1447 patients were included. Our analyses found no differences between patients treated with or without beta-blockers for either myocardial infarction (RR 1.08; 95% CI, 0.61-1.91) or all-cause mortality (RR 0.75; 95% CI, 0.46-1.24). Heterogeneity among included studies was low to moderate.Conclusion
This systematic review and meta-analysis suggests that beta-blocker use is not associated with adverse clinical outcomes in patients presenting with acute chest pain related to cocaine use. 相似文献11.

Background
Prior research has demonstrated high mortality rates in patients with cirrhosis who contract bacterial infections. The purpose of our study was to explore clinical outcomes such as 90-day mortality, rehospitalization, and intensive care unit (ICU) admission in older veterans with pneumonia and cirrhosis.Methods
We conducted a retrospective cohort study of hospitalized patients with community-acquired pneumonia at any Departments of Veterans Affairs (VA) hospital over a 10-year period. We included patients 65 years or older who consistently received VA care and who were diagnosed with community-acquired pneumonia. There were 103,997 patients who met the inclusion criteria, and 1,246 patients with cirrhosis. We used multilevel regression models to examine the association between cirrhosis and the outcomes of interest after controlling for potential confounders.Results
Cirrhosis was associated with significantly increased odds of 90-day mortality (odds ratio 1.79, 95% confidence interval, 1.57-2.04). There were also significantly increased odds of rehospitalization within 90-days (1.30, 1.16-1.47). No significant association was found with ICU admission (1.00, 0.83-1.19).Conclusions
We found an association between cirrhosis and 90-day mortality and rehospitalization in older patients with pneumonia. We suggest that physicians should carefully monitor patients with cirrhosis who develop pneumonia. 相似文献13.

Background
Severe pneumonia is responsible for great mortality and morbidity worldwide, and early-applied effective anti-infective therapy can improve the prognosis of patients. However, identification of infectious agents in severe pneumonia remains a major challenge so far. In this study, the potential utility of transmission electron microscopy (TEM) in detecting nonbacterial pathogens in patients with severe pneumonia was retrospectively evaluated.Materials and Methods
A total of 106 patients diagnosed with severe pneumonia at our hospital from September 2015 to December 2017 were included, and their baseline clinical characteristics were collected. Nonbacterial infectious agents detected by TEM in bronchoalveolar lavage fluid (BALF) and serological tests were summarized. The detection rates were further compared between TEM and serological tests.Results
BALF examination under the transmission electron microscope revealed 24 viruses, 16 mycoplasmas, 18 chlamydia, 2 fungi and 74 bacteria in 99 samples, among which 61 samples were mixed infections. The combined use of serological tests and TEM significantly improved the detection rate of nonbacterial infectious agents in patients with severe pneumonia.Conclusions
Our data support that implementation of TEM could improve the sensitivity for detecting viruses, atypical pathogens and mixed infections in BALF from patient of severe pneumonia. Therefore, TEM may be used as an auxiliary diagnostic method of other microbiological tests in severe pneumonia. 相似文献14.

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15.

Background
To examine the clinical and economic burdens associated with delayed receipt of appropriate therapy among patients with Gram-negative bacteria (GNB) infections, stratified by antibiotic resistance status.Materials and Methods
Retrospective analysis using the Premier Hospital Database. Adult admissions (July 2011-September 2014) with evidence of complicated urinary tract infection, complicated intra-abdominal infection, hospital-associated pneumonia, or bloodstream infection, length of stay (LOS) ≥1 days and a positive GNB culture from a site consistent with infection type (culture draw date?=?index date) were identified and stratified by antibiotic susceptibility to index pathogens. Delayed appropriate therapy was defined as no receipt of antibiotic(s) with relevant microbiological activity on or within 2 days of index date. Inverse probability weighting and multivariate regression analyses were used to estimate the association between delayed appropriate therapy and outcomes. Generalized linear models were used to evaluate postindex duration of antibiotic therapy, LOS and total in-hospital costs. Logistic models were used to evaluate discharge destination and in-hospital mortality/discharge to hospice.Results
A total of 56,357 patients with GNB infections were identified (resistant, n?=?6,055; susceptible, n?=?50,302). Delayed appropriate therapy was received by 2,800 (46.2%) patients with resistant and 16,585 (33.0%) patients with susceptible infections. Using multivariate analysis, delayed appropriate therapy was associated with worse outcomes including ～70% increase in LOS, ～65% increase in total in-hospital costs and ～20% increase in the risk of in-hospital mortality/discharge to hospice, regardless of susceptibility status.Conclusions
Our results suggest that outcomes in patients with GNB infections, regardless of resistance status, significantly improve if timely appropriate therapy can be provided. 相似文献16.

Rationale
Red blood cells (RBC) undergo morphologic and biochemical changes during storage which may lead to adverse health risks upon transfusion. In prior studies, the effect of RBC age on health outcomes has been conflicting. We designed the study to assess the effects of RBC units’ storage duration on health outcomes specifically for hospitalized patients undergoing hip fracture surgery or coronary artery bypass grafting (CABG) surgery.Methods
Using International Classification of Diseases (ICD) 9 codes, hip fracture surgery and CABG surgery patients, who received RBC transfusions between 2008 and 2013, were retrospectively identified from the electronic medical records system. Hip fracture surgery and CABG cohorts were sub-divided into 3 blood age groups based upon RBC unit age at the time of transfusion: young blood (RBC units stored less than or equal to 14 days), old blood (RBC units were stored for greater than or equal to 28 days), or mixed blood for the remaining patients. Outcome variables were 30-day, 90-day, and inpatient mortality as well as hospital length of stay.Results
A total of 3,182 patients were identified: 1,121 with hip fractures and 2,061 with CABG. Transfusion of old blood was associated with higher inpatient mortality in the hip fracture surgery cohort (OR 166.8, 95% CI 1.067-26064.7, p?=?0.04) and a higher 30-day mortality in the CABG cohort (OR 4.55, 95% CI 1.01–20.49, p?=?0.03).Conclusions
Transfusing RBC units stored for greater than or equal to 28 days may be associated with a higher mortality for patients undergoing hip fracture or CABG. 相似文献17.
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18.

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19.

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20.
