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2.

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3.
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4.

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5.

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.

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8.

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10.

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11.

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12.

Objectives
To date, all studies addressing on anti-inflammatory drugs in PsA have been carried out in psoriatic arthritis (PsA) patients with polyarticular disease. Specific studies on enthesitis are missing. IL-23 is considered to play a central role in the development of enthesitis. We therefore speculated that therapeutic inhibition of IL-12/IL-23 is particularly effective in enthesitis-driven PsA patients.Methods
Enthesial CLearance In PSoriatic Arthritis (ECLIPSA) is a prospective randomized-controlled open-label study. Patients with PsA with active enthesitis were randomized 1:1 to receive either ustekinumab (UST; arm 1) or tumor necrosis factor inhibitors (TNFi; arm 2). Primary endpoint was complete clearance of enthesitis, defined by Spondyloarthritis Research Consortium of Canada (SPARCC) index equal to zero at 24 weeks.Results
51 patients (UST?=?25; TNFi?=?26) were screened, 47 enrolled (UST?=?23; TNFi?=?24) and 46 completed the study. Mean?±?SD SPARCC index at baseline was 4.8?±?2.6 in the UST group and 3.5?±?2.3 in the TNFi group with no significant difference. After 24 weeks, 73.9% of UST patients and 41.7% of TNFi patients reached the primary endpoint (SPARCC?=?0) indicating clearance from enthesitis (p?=?0.018). UST achieved superior responses as compared to TNFi with respect to enthesitis (p?=?0.007) and psoriatic skin disease (p?=?0.030) but not for arthritis (p?=?0.95).Conclusion
These results indicate that p40-IL-12/IL-23 inhibition is superior to TNFi in the clearance of enthesitis. Future stratified therapeutic approaches in PsA patients may therefore consider the presence or absence of enthesitis as a discriminator of response between different cytokine blocking modalities. 相似文献13.

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15.

Background
Rheumatoid arthritis (RA) has articular and non-articular manifestations. Early, intensive treatment has substantial benefit for both. This requires patients be identified as soon as symptoms develop.Objectives
To determine whether selected signs and symptoms can be identified in the primary care records of patients prior to a formal diagnosis of RA being made and, if so, how early they can be identified.Methods
A case-control study was constructed within the UK Clinical Practice Research Datalink (CPRD). 3577 individuals with ‘definite’ RA, were matched to 14,287 individuals without inflammatory arthritis. An index date was established (i.e., date general practitioner (GP) first appeared to suspect RA). Rates of consultation and consultations for suspected early RA symptoms were compared in cases and controls in the two years prior to the index date using conditional logistic regression, adjusted for number of consultations.Results
The mean (standard deviation) age of participants was 58.8 (14.5) years and 66.8% were female. Rates of any consultation were significantly higher in RA cases than in controls for at least two years prior to the index date. Cases were more likely to have a pre-diagnosis coded consultation for joint, and particularly hand symptoms (aOR 11.44 (9.60, 13.63)), morning stiffness (8.10 (3.54, 18.5)), carpal tunnel syndrome (4.57 (3.54, 5.88)) and other non-articular features.Conclusions
In patients who develop RA, GP consultation rates are higher for at least two years prior to the first recorded suspicion of RA. This study highlights symptoms that should raise a GP's index of suspicion for RA. 相似文献17.

Background
Acute graft versus host disease (aGVHD) affects approximately 30–60% of patients after allogeneic hematopoietic stem cell transplantation (HCT) and our ability to predict who develops this complication and their response to treatment is limited. Fecal calprotectin has recently gained popularity as an effective marker of GI inflammation in patients with Inflammatory Bowel Disease (IBD).Methods
Fecal calprotectin and albumin were evaluated as prognostic and predictive markers of aGVHD in 60 adult and pediatric HCT patients. Stool samples were sent for calprotectin quantification prior to starting conditioning, at day 14 post-HCT, at day 28 post-HCT, and at onset of aGVHD ±?2 days.Results
Fecal calprotectin did not differentiate patients with GI-GVHD and non-GI GVHD and did not vary based on severity. However, in patients with steroid-refractory GI aGVHD, significantly higher fecal calprotectin levels were noted. At onset of lower-GI symptoms, steroid refractory patients (n?=?3) had a mean fecal calprotectin level of 449?ug/g (range 116–1111?ug/g) and a mean albumin of 1.93?g/dL (range 1.6–2.3?g/dL) compared with a mean fecal calprotectin of 24?ug/g (range 16–31?ug/g) and a mean albumin of 3.3?g/dL (range 2.3–3.9?g/dL) in steroid responsive patients (n?=?9) (fecal calprotectin p?=?0.032, albumin p?=?0.027).Conclusion
Patients with steroid-refractory GI aGVHD had higher fecal calprotectin levels and lower albumin levels than patients with steroid-responsive disease. We recommend further studies to evaluate non-invasive tests with fecal calprotectin in combination with albumin in predicting steroid refractory disease at onset of symptoms to potentially identify patients that may benefit from upfront escalation in GVHD treatment. 相似文献18.

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19.

Background
Monocyte-platelet interaction may favor the development of a proatherogenic monocyte phenotype. It is still uncertain which of the 3 monocyte subpopulations interact with platelets to form monocyte-platelet aggregates (MPAs) in acute myocardial infarctions. The aim of our study was to evaluate the monocyte subsets, the percentage of MPAs and the involvement of monocyte subsets in MPA formation among patients with ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI), and compared to patients with stable angina (SA).Methods
Monocyte subsets and MPAs formation were measured in blood collected in 3.2% sodium citrate tubes by means of flow cytometry.Results
Classical, intermediate and nonclassical monocyte percentages were statistically different when comparing patients with STEMI and NSTEMI. Moreover, classical and intermediate monocytes were statistically different when comparing the STEMI and SA group; however, only the classical monocyte subset was found to be higher in the acute myocardial infarction group compared to the SA group. The percentage of MPAs was significantly higher in STEMI (50.1%) compared to NSTEMI (22.9%). We found no differences in the involvement of monocyte subsets in MPA formation between patients with STEMI and NSTEMI and in comparison with the SA group.Conclusions
These findings suggest that the increase in circulating levels of classical monocytes in patients with STEMI as compared to NSTEMI reflects the severity of the acute event. The increased percentage of MPAs may favor the development of STEMI compared to NSTEMI. 相似文献20.
