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
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
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5.

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6.

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7.

Objectives
Rheumatoid factors (RFs) are thought to play an important role in rheumatoid arthritis (RA), but are also found in healthy donors (HDs). Previous studies examined variable region sequences of these autoantibodies at a time when knowledge of the human germline repertoire was incomplete. Here we collected and analyzed RF sequence data from the literature to elucidate how RFs develop and whether their characteristics differ between RA patients and HDs.Methods
A database was built containing nucleotide sequences of RF heavy and light chain variable domains and characteristics including affinity, isotype and specificity, all collected from published papers. Gene usage and mutation frequencies were analyzed using IMGT/HiV-QUEST. Selection strength was assessed with the BASELINe tool.Results
Sequences were retrieved for 183 RF clones (87 RA; 67 HDs; 29 other). No biased gene usage was observed for RA and HDs. However, there does appear to be skewed gene usage in RFs from patients with mixed cryoglobulinemia. Mutation frequency varies considerably between RFs, and isotype-switched clones have significantly more mutations. Monospecific RFs carry more mutations than polyspecific RFs; no difference was found for RA- versus HD-derived RFs. Overall, reported affinity is low (median 1 µM), with a non-significant trend toward higher affinity of RA-derived RFs. Mutation frequency and affinity did not appear to be correlated. BASELINe analysis suggests an overall lack of positive selection and less negative selection strength in RA-derived RFs.Conclusions
RFs derived from RA patients have similar properties as those derived from HDs. The RF response can be characterized as a moderately matured autoantibody response, with variable levels of somatic hypermutation, but low affinity. 相似文献8.

Objective
Biologic anti-rheumatic drugs are used with less frequency among older patients compared to young patients. This population is less represented in studies performed to evaluate the efficacy and safety of this drugs. We aimed to assess the efficacy and safety of biological agents between the older RA patients compared to young.Methods
A comprehensive, systematic search was conducted in major indexing databases using key terms for RA and each biological agent. The review process was completed by 2 investigators. Both randomized controlled trials and observational studies of at least 6-month duration conducted in adult RA patients were included. Outcomes of interest were clinical efficacy and safety. Effect-estimates were pooled using random-effects modeling if 4 or more studies used the same scale and time-frame for measuring outcomes.Results
24 studies (16 focusing on anti-TNF agents) representing 63,705 patients (24% were older) were included. Older RA patients had worse baseline RA disease activity, longer disease duration at the time of enrollment in the trial (14.4?±?3.6 vs. 10.9?±?3.6 years; p?<?0.001) and higher steroid use (73.2 vs. 64.7%, p?<?0.001) than younger. 5 out of 6 studies assessing anti-TNF agents showed worse efficacy outcomes in older patients. The pooled OR of infection and ADRs with anti-TNF agents in older compared to young RA patients was OR 1.59 (95% CI: 1.45–1.76) and 1.40 (95% CI: 1.23–1.61) respectively.Conclusions
Older patients had worse safety and efficacy with biological agents but also had worse baseline disease activity. There was significant heterogeneity in reporting outcomes and very limited studies in biological agents other than anti-TNF drugs. 相似文献9.

Objectives
To estimate the size of unmet needs in the treatment of early Rheumatoid Arthritis (eRA), using all the conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and/or biological DMARDs (bDMARDs) in a long-term observational study.Materials and methods
538 patients with eRA were evaluated. The 2010 ACR/EULAR classification criteria were used. All patients were csDMARDs and bDMARDs-naive with disease duration less than one year. They were treated according to EULAR and ACR recommendations for RA. All the csDMARDs and bDMARDs were used. Clinical, laboratory findings with the disease activity score-28 and treatment decisions were all recorded as well as adverse drug reactions, reason of therapy termination, disease complications and comorbidities.Results
Methotrexate (58%) and Infliximab (37%) where the first csDMARD and bDMARD choice respectively. During follow-up, 14 patients were lost and 7 developed comorbidities. The final results are referred to 517 patients. Among those, 66% were treated with csDMARDs as monotherapy or in combination therapy with sustained low disease activity (LDA). However, 3.2% from this group neither achieved LDA, nor received bDMARDs, due to comorbidities. On the other hand, 34% were treated with bDMARDs with or without csDMARDs. The majority of them demonstrated sustained LDA. From this group, 17.7% never achieved LDA, despite that they switched and received all bDMARDs. Thus, 20.9% of our patients never achieved LDA.Conclusions
Using the current recommendations for RA therapy we successfully treated the majority of our patients. However, we found that the size of gap and the unmet needs for treatment is about 20%. 相似文献10.

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11.

Background
The Beck Depression Inventory (BDI-II) may be used to evaluate individuals for symptoms of depression.Methods
In a 1-year prospective study, 52 adult Lyme disease patients with erythema migrans and 104 matched control subjects were clinically assessed and completed the BDI-II at study entry and approximately 6 and 12 months later following antibiotic treatment.Results
The mean BDI-II score was significantly higher at the baseline visit among Lyme disease patients compared with controls (P?=?.002), but no significant differences between the groups were observed at either the 6- or 12-month study visits. Over the course of the study, the mean BDI-II scores decreased an average of approximately 0.22 points per month (P < .0005) for Lyme disease patients, whereas the mean scores changed very little for controls (mean change?=??0.02 per month, P?=?.50). The total number of somatic symptoms, of the 12 symptoms evaluated, strongly and directly correlated with the BDI-II scores at the baseline visit for the Lyme disease patients.Conclusions
The mean BDI-II scores of patients with early Lyme disease significantly exceeded that of matched controls at study entry, but by 6 months the values did not differ significantly. There was a good-to-excellent direct correlation between the BDI-II score and the total number of symptoms, suggesting that the BDI-II scores were reflecting somatic rather than affective depressive symptoms. When using the BDI-II as an assessment tool of patients with Lyme disease, infection-related somatic symptoms per se need to be considered in the interpretation of the results. 相似文献12.

Objectives
To identify the breadth of the literature regarding patients’ perceived health information needs related to inflammatory arthritis care.Methods
A systematic scoping review of MEDLINE, EMBASE, CINAHL and PsycINFO was performed to identify relevant articles (1990 -2016) examining patients’ perceived needs relating to health information in inflammatory arthritis. Data and themes were identified and categorised and risk of bias assessed.Results
Twenty nine studies (11 quantitative, 14 qualitative and 4 mixed methods) from 4121 identified articles were relevant for inclusion. Most focussed on rheumatoid arthritis. Key findings included: (1) Reasons for seeking health information often focussed on gaining ownership over their condition and facilitating self-management. (2) Demographic differences in information needs were inconsistent, but women and younger patients generally reported more needs. (3) Desired information content was broad, and included targeted and practical information covering disease treatment and psychosocial wellbeing. (4) Preferred information delivery method was consultation with a Rheumatologist; however group sessions had advantages for psychosocial issues while written information provided useful supplementation. (5) Barriers to meeting health information needs were around timely access.Conclusions
Patients with inflammatory arthritis have high information needs, desiring practical and individualised information. When developing strategies to meet patients’ information needs, aligning patient expectations with delivery methods that are accessible, cost-effective and flexible may help to optimize patient outcomes. 相似文献13.

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14.

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15.

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
There is a discrepancy between evidence in support of the widespread use of intra-articular hyaluronic acid (IAHA) to treat knee osteoarthritis (OA) in clinical practice, and the often discordant recommendations from multiple international guideline committees, which requires further investigation.Methods
We conducted a literature review to determine the strength of evidence in support of the efficacy and safety of IAHA, from randomized controlled trials and meta-analyses.Results
Our analysis shows that IAHA provides a moderate symptomatic benefit to knee OA patients and without major safety concerns. In fact, IAHA may offer one of the best benefit/risk ratios among pharmacologic options, as measured by improvements in knee OA health outcomes, overall gain in quality-adjusted life years and substantial delays in time to total knee replacement.Conclusions
We advocate for the consideration of recommending IAHA injection as a treatment option in the management of knee OA, tailored by disease stage and patient phenotype. Future research efforts should focus on identification of OA patient subgroups that demonstrate a more robust response to IAHA, determination of long-term effects of repeat IAHA injections on patient-reported outcomes and total knee replacement-sparing effect, further elucidation of disease-modifying effects, and the potential for combination therapy with other pharmacologic and non-pharmacologic therapies to optimize the management of knee OA. 相似文献20.
