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2.

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3.

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4.

Background
The present study performed a meta-analysis of randomized and prospective trials to compare the outcomes of percutaneous coronary intervention (PCI) with stents versus coronary artery bypass graft surgery (CABG) for unprotected left main coronary artery (UPLM) stenosis.Methods
The Cochrane Library, PubMed and EMBASE databases were systematically searched until July 2017. The Newcastle-Ottawa scale was used for quality assessment.Results
A total of 19 studies with 16,900 participants were included. Pooled analysis showed no significant differences in all-cause mortality (odds ratio [OR] 0.94; 95% CI 0.74-1.20) and cardiac death (OR 1.04; 95% CI 0.74-1.47). However, subgroup analysis showed that PCI was associated with a low all-cause mortality rate at 30-day follow up (OR 0.48; 95% CI 0.26-0.89). The stroke rate in PCI was lower in short-term follow up (OR 0.45; 95% CI 0.23-0.88) and long-term follow up (OR 0.36; 95% CI 0.27-0.47). On the other hand, PCI was associated with higher risk of myocardial infarction (OR 1.59; 95% CI 1.34-1.88), repeat revascularization (OR 2.47; 95% CI 1.80-3.37) and target vessel revascularization (OR 2.10; 95% CI 1.72-2.57) compared to CABG in the pooled analysis.Conclusions
The current evidence suggests that the risk of stroke was significantly reduced in PCI compared to that in CABG. Therefore, PCI is the preferred treatment for patients with a high risk of stroke. Additionally, in short-term follow up, PCI was reported to be safe and effective for UPLM patients compared to CABG. However, CABG caused fewer complications long term. 相似文献5.

Background
Nonspecific ST-T repolarization (NST) abnormalities alter the ST-segment for reasons often unrelated to acute myocardial ischemia, which could contribute to misdiagnosis or inappropriate treatment. We sought to define the prevalence of NST patterns in patients with chest pain and evaluate how such patterns correlate with the eventual etiology of chest pain and course of hospitalization.Methods
This was a prospective observational study that included consecutive prehospital chest pain patients from three tertiary care hospitals in the U.S. Two independent reviewers blinded from clinical data audited the prehospital 12-lead ECG for the presence or absence of NST patterns (i.e., right or left bundle branch block, left ventricular hypertrophy with strain pattern, ventricular pacing, ventricular rhythm, or coarse atrial fibrillation). The primary outcome was 30-day major adverse cardiac events (MACE) defined as cardiac arrest, acute heart failure, post-discharge infarction, or all-cause death.Results
The final sample included 750 patients (age 59 ± 17, 58% males). A total of 40 patients (5.3%) experienced 30-MACE and 131 (17.5%) had NST patterns. The presence of NST patterns was an independent multivariate predictor of 30-day MACE (9.9% vs. 4.4%, OR = 2.2 [95% CI = 1.1–4.5]. Patients with NST patterns had increased median length of stay (1.0 [IQR 0.5–3] vs. 2.0 [IQR 1–4] days, p < 0.05) independent of the etiology of chest pain.Conclusions
One in six prehospital ECGs of patients with chest pain has NST patterns. This pattern is associated with increased length of stay and adverse cardiac outcomes, suggesting the need of preventive measures and close follow up in such patients. 相似文献6.

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7.

Objectives
Tuberculosis (TB) is a serious re-emergent public health problem in the UK. In response to rising case incidence a National TB Strain-Typing Service based on molecular strain-typing was established. This facilitates early detection and investigation of clusters, targeted public health action, and prevention of further transmission. We review the added public health value of investigating molecular TB strain-typed (ST) clusters.Methods
A structured questionnaire for each ST cluster investigated in England between 1 January 2010 and 30 June 2013 was completed. Questions related to epidemiological links and public health action and the perceived benefits of ST cluster investigation.Results
There were 278 ST cluster investigations (CIs) involving 1882 TB cases. Cluster size ranged from 2 to 92. CIs identified new epidemiological links in 36% of clusters; in 18% STs were discordant refuting transmission thought to have occurred. Additional public health action was taken following 23% of CI.Conclusions
We found positive benefits of TB molecular ST and CI, in identifying new epidemiological links between cases and taking public health action and in refuting transmission and saving resources. This needs to be translated to a decrease in transmission to provide evidence of public health value in this low prevalence high resource setting. 相似文献8.

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9.

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10.

Purpose
The purpose of this study was to test a pharmacist-led intervention to improve gout treatment adherence and outcomes.Methods
We conducted a site-randomized trial (n=1463 patients) comparing a 1-year, pharmacist-led intervention to usual care in patients with gout initiating allopurinol. The intervention was delivered primarily through automated telephone technology. Co-primary outcomes were the proportion of patients adherent (proportion of days covered ≥0.8) and achieving a serum urate <6.0 mg/dl at 1 year. Outcomes were reassessed at year 2.Results
Patients who underwent intervention were more likely than patients of usual care to be adherent (50% vs 37%; odds ratio [OR] 1.68; 95% confidence interval [CI] 1.30, 2.17) and reach serum urate goal (30% vs 15%; OR 2.37; 95% CI 1.83, 3.05). In the second year (1 year after the intervention ended), differences were attenuated, remaining significant for urate goal but not for adherence. The intervention was associated with a 6%-16% lower gout flare rate during year 2, but the differences did not reach statistical significance.Conclusions
A pharmacist-led intervention incorporating automated telephone technology improved adherence and serum urate goal in patients with gout initiating allopurinol. Although this light-touch, low-tech intervention was efficacious, additional efforts are needed to enhance patient engagement in gout management and ultimately to improve outcomes. 相似文献11.

Background
Previous studies have found that obestatin significantly inhibited water drinking and reduced the arginine vasopressin levels in the brain to decrease renal water reabsorption. However, obestatin is unable to cross the blood-brain barrier. Its effect on the body's kidney water metabolism in peripheral remains unknown.Materials and Methods
Expression and subcellular distribution of aquaporin 2 (AQP2) were detected by immunoblotting and immunofluorescence in mouse inner medullary collecting duct-3 (mIMCD-3) cells and congestive heart failure model rats. Moreover, expression of phosphorylated AQP2 (P-AQP2; Ser256) in mIMCD-3 cells was evaluated by immunoblotting.Results
After a 30-minute treatment with obestatin in mIMCD-3 cells and congestive heart failure model rats, the AQP2 plasma membrane distribution decreased, while AQP2 protein level, P-AQP2 (Ser256) protein level and phosphorylation ratio of AQP2 showed no significant change.Conclusions
These findings suggest that obestatin has a short-term regulatory effect on the AQP2 plasma membrane distribution. In addition, obestatin decreases the APQ2 plasma membrane distribution probably by promoting the endocytosis of AQP2. 相似文献13.

Background
Several cardiotoxic substances impact heart failure incidence. The burden of comorbid tobacco or substance use disorders among heart failure patients is under-characterized. We describe the burden of tobacco and substance use disorders among hospitalized heart failure patients in the United States.Methods
We calculated the proportion of primary heart failure hospitalizations in the 2014 National Inpatient Sample with tobacco or substance use disorders accounting for demographic factors.Results
Of 989,080 heart failure hospitalizations, 15.5% (n?=?152,965) had documented tobacco (n?=?119,285, 12.1%) or substance (n?=?61,510, 6.2%) use disorder. Female sex was associated with lower rates of tobacco (odds ratio [OR] 0.72; 95% confidence interval [CI], 0.70-0.74) and substance (OR 0.37; 95% CI, 0.36-0.39) use disorder. Tobacco and substance use disorder rates were highest for hospitalizations <55years of age. Native American race was associated with increased risk of alcohol use disorder (OR 1.67; 95% CI, 1.27-2.20) and black race with alcohol (OR 1.09; 95% CI, 1.02-1.16) or drug (OR 1.63; 95% CI, 1.53-1.74) use disorder. Medicaid insurance or income in the lowest quartile were associated with increased risk of tobacco and substance use disorders.Conclusions
Tobacco and substance use disorders affect vulnerable heart failure populations, including those of male sex, younger age, lower socioeconomic status, and racial/ethnic minorities. Enhanced screening for tobacco and substance use disorders in hospitalized heart failure patients may reveal opportunities for treatment and secondary prevention. 相似文献15.

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16.
Background
Sharps injuries occur often among surgical staff, but they vary considerably.Methods
We searched PubMed and Embase for studies assessing the incidence of sharps injuries. We combined the incidence rates of similar studies in a random effects meta-analysis and explored heterogeneity with meta-regression.Results
We located 45 studies of which 11 were randomized control trials, 15 were follow-up studies, and 19 were cross-sectional studies. We categorized injuries as self-reported, glove perforations, or administrative injuries. We calculated the population at risk as person-years and as person-operations (po). Meta-analysis of the incidence rate based on the best outcome measure resulted in 13.2 injuries per 100 time-units (95% confidence interval [CI], 4.7-37.1; I2?=?100%). Per 100 person-years, the injury rate was 88.2 (95% CI, 61.3-126.9; 21 studies) for self-reported injuries, 40.0 for perforations (95% CI, 19.2-83.5; 15 studies), and 5.8 for administrative injuries (95% CI, 2.7-12.2; 5 studies). Per 100 po, the respective figures were 2.1 (95% CI, 0.8-5.0; 4 studies), 11.1 (95% CI, 6.6-18.9, 15 studies), and 0.1 (95% CI, 0.05-0.21). I2 values were all above 90%. Meta-regression indicated lower incidence rates in studies that used perforations per po.Conclusions
A surgeon will have a sharps injury in about 1 in 10 operations . Reporting of sharps injuries in surgical staff should be standardized per 100 po and be assessed in prospective follow-up studies. 相似文献17.

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18.

Background
This study assessed the effect of ibandronate (IBN), a farnesyl pyrophosphate synthase (FPPS) inhibitor, on vascular remodeling in diabetic rats.Methods
A rat model of diabetes was induced by a high-fat and high-sugar diet combined with a small dose of streptozotocin. The diabetic rats received 5 µg/kg of ibandronate solution or normal saline subcutaneously every morning for 16 weeks. The morphology of the thoracic aorta was assessed by hematoxylin and eosin and Masson's trichrome staining techniques. Gene expression levels of connective tissue growth factor (CTGF) and FPPS were assessed by quantitative real-time polymerase chain reaction (qRT-PCR) analysis. CTGF and FPPS protein levels were determined by Western blotting analysis.Results
Rats with diabetes mellitus showed moderate hyperglycemia, insulin resistance, hyperlipidemia and thoracic aortic fibrosis. FPPS was significantly upregulated in the thoracic aorta from diabetic animals. Interestingly, IBN treatment for 16 weeks alleviated the diabetes-induced histopathologic changes in the thoracic aortic wall and reduced CTGF protein and mRNA levels.Conclusions
These findings provided evidence that FPPS is involved in thoracic aortic fibrosis in diabetic rats. Meanwhile, IBN could alleviate vascular remodeling in diabetic animals. 相似文献19.

Objectives
Fibromyalgia is a condition which exhibits chronic widespread pain with neuropathic pain features and has a major impact on health-related quality of life. The pathophysiology remains unclear, however, there is increasing evidence for involvement of the peripheral nervous system with a high prevalence of small fiber pathology (SFP). The aim of this systematic literature review is to establish the prevalence of SFP in fibromyalgia.Methods
An electronic literature search was performed using MEDLINE, EMBASE, PubMed, Web of Science, CINAHL and the Cochrane Library databases. Published full-text, English language articles that provide SFP prevalence data in studies of fibromyalgia of patients over 18years old were included. All articles were screened by two independent reviewers using a priori criteria. Methodological quality and risk of bias were evaluated using the critical appraisal tool by Munn et al. Overall and subgroup pooled prevalence were calculated by random-effects meta-analysis with 95% CI.Results
Database searches found 935 studies; 45 articles were screened of which 8 full text articles satisfied the inclusion criteria, providing data from 222 participants. The meta-analysis demonstrated the pooled prevalence of SFP in fibromyalgia is 49% (95% CI: 38–60%) with a moderate degree of heterogeneity, (I2=?68%). The prevalence estimate attained by a skin biopsy was 45% (95% CI: 32–59%, I2=?70%) and for corneal confocal microscopy it was 59% (95% CI: 40–78%, I2=?51%).Conclusion
There is a high prevalence of SFP in fibromyalgia. This study provides compelling evidence of a distinct phenotype involving SFP in fibromyalgia. Identifying SFP will aid in determining its relationship to pain and potentially facilitate the development of future interventions and pharmacotherapy. 相似文献20.
