Background
Frailty and acute kidney injury are independently associated with an increased risk of morbidity and mortality. The degree of frailty can be assessed by the Clinical Frailty Score (CFS). This study assessed whether an individual's CFS was associated with acute kidney injury in acute elderly medical admissions and recorded the short-term outcomes.Methods
This was a single-center prospective observational cohort study. All patients aged ≥65 years admitted under an acute medical take over 12 nonconsecutive days were included. Patient demographics, comorbidities, baseline CFS, and renal status on admission were recorded. Outcomes of death, length of stay, and hospital re-attendance were assessed 2 weeks following admission.Results
Of 164 patients (77 males), 19% had acute kidney injury on admission and 22% were considered severely frail. Severe frailty was associated with acute kidney injury (P = .01) and death within 2 weeks (P = .01). Two-week mortality was highest among patients with both (36%).Conclusion
The incidence of acute kidney injury in “severely frail” acutely unwell elderly patients is significantly higher and associated with an increased short-term mortality. The CFS may be useful in acute illness to guide clinical decisions in elderly patients. 相似文献2.

Objective
Oxygen therapy is frequently used for patients with acute myocardial infarction. The aim of this study is to perform a systematic review and meta-analysis to compare the outcomes of oxygen therapy versus no oxygen therapy in post–acute myocardial infarction settings.Methods
A systematic search of electronic databases was conducted for randomized studies, which reported cardiovascular events in oxygen versus no oxygen therapy. The evaluated outcomes were all-cause mortality, recurrent coronary events (ischemia or myocardial infarction), heart failure, and arrhythmias. Summary-adjusted risk ratios (RRs) were calculated by the random effects DerSimonian and Laird model. The risk of bias of the included studies was assessed by Cochrane scale.Results
Our meta-analysis included a total of 7 studies with 3842 patients who received oxygen therapy and 3860 patients without oxygen therapy. Oxygen therapy did not decrease the risk of all-cause mortality (pooled RR, 0.99; 95% confidence interval [CI], 0.81-1.21; P = .43), recurrent ischemia or myocardial infarction (pooled RR, 1.19; 95% CI, 0.95-1.48; P = .75), heart failure (pooled RR, 0.94; 95% CI, 0.61-1.45; P = .348), and occurrence of arrhythmia events (pooled RR, 1.01; 95% CI, 0.85-1.2; P = .233) compared with the no oxygen arm.Conclusions
This meta-analysis confirms the lack of benefit of routine oxygen therapy in patients with acute myocardial infarction with normal oxygen saturation levels. 相似文献3.

Background
The neutrophil to lymphocyte ratio (NLR), has been proposed as potential indicator of cardiovascular events. Our aim was to determine the relationship between NLR and development of myocardial injury after non-cardiac surgery (MINS).Methods
This observational cohort study included 255 consecutive noncardiac surgery patients aged ≥45 years. Electrocardiography recordings and high sensitivity cardiac troponin T (hscTnT) levels of the patients were obtained for a period of 3 days postoperatively.Results
MINS was detected in 30 (11.8%) patients using the cut-off level of ≥14 ng/L for hscTnT. In the MINS group NLR (3.79 ± 0.7 vs. 2.69 ± 0.6, p < 0.000) values were higher than non-NLR group. The NLR to be independently associated with the development of MINS (OR: 11.690; CI: 4.619–29.585, p < 0.000).Conclusions
NLR seems to be a simple, easy and cheap tool to predict the development of MINS in patient undergoing non-cardiac surgery. 相似文献4.

Background
Sedation of mechanically ventilated patients should optimize comfort and safety while avoiding over-sedation and adverse outcomes. To our knowledge, characteristics associated with attaining target sedation are unknown.Objectives
Evaluate current sedation practice at a single center and explore which patient characteristics are associated with attaining target sedation.Methods
This is a single-center, retrospective chart review of sedated, ventilated patients in a medical/surgical ICU. Demographic and clinical data were collected. Univariate and multivariate logistic regression analyses were used with attaining target sedation as the dependent variable.Results
Of the 100 patients included (median 60.5 years), 50 attained target sedation. Univariate analyses (a = 0.10) revealed factors associated with target sedation were age (P = 0.08), history of alcohol abuse (P = 0.08), multiple comorbidities (P = 0.09), and delirium monitoring (P = 0.002). Multivariate analysis revealed an association between delirium monitoring/documentation and attaining target sedation (P = 0.005; OR 9.2; 95% CI 2.3–36.8).Conclusions
Patients without appropriate delirium monitoring/documentation had significantly reduced likelihood of achieving target sedation. 相似文献5.

Background
Pulmonary arterial hypertension (PAH) has a delay in diagnosis that makes time since diagnosis of interest in this population.Objectives
To assess psychological conditions, perceived stress, QOL, and interpersonal support and to explore whether these factors may correlate with time since diagnosis in patients with PAH.Methods
Participants at an academic medical center (n = 108) completed psychological questionnaires (Cambridge Pulmonary Hypertension Outcome Review, Patient Health Questionnaire-9, Perceived Stress Scale-10, and Interpersonal Support Evaluation List-Short Form).Results
Prevalence of psychiatric disorder, major depression, and “other depressive disorder” were 29.6%, 15.7%, and 9.3%, respectively. Participants reported adequate social support, high perceived stress, and average quality of life. Time since diagnosis was positively associated with greater perceived social support (ρ = 0.174, p = .075) and greater perceived stress (ρ = 0.191, p = .048), but no other psychological factor.Conclusions
Routine psychological assessment and timely referral for mental health services are suggested. Social support may buffer patients from stress. 相似文献6.

Background
Concerns remain about the burden of nursing care required to implement pulmonary artery pressure monitoring of heart failure patients.Methods
We conducted a retrospective analysis of patients (N = 15) with a PAP sensor at our center. We defined three categories of PAP activity and estimated the nursing time spent on PAP monitoring.Results
During the 6 months after implantation, the median patient contact time was 67 (55–75) minutes/patient/month and the median frequency of patient contact was 5.8 (4.6–6.4) contacts/patient/month. The intensity of nurse-patient contact decreased after the first 3 months (81 [52–102] minutes/patient/month vs. 45 [29–61] minutes/patient/month; P = 0.005).Conclusions
The intensity of nurse-patient contact increased significantly after PAP sensor implantation but declined after the first 3 months with medical stabilization. These data from our center may serve as a benchmark to project the nursing time required to support PAP monitoring in practice. 相似文献7.

Background
Social support and mastery are important aspects in the treatment of chronic diseases, however their role in connection with Obstructive Sleep Apnoea (OSA) remains unclear.Objectives
The study examined the associations between social support, mastery, sleep-related problems and functional status in untreated OSA patients.Methods
All patients in this cross-sectional study completed the Multidimensional Scale of Perceived Social Support, the Pearlin Mastery Scale, the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale and the Functional Outcomes of Sleep Questionnaire. Multiple linear regression and mediation analyses were used to analyse the data.Results
Participants were 150 newly diagnosed OSA patients (Apnoea-Hypopnoea Index–AHI≥5; 68% male; mean age 48.9 ± 9.5years). Compared with social support, mastery was more strongly associated with functional status. The indirect effects of sleep-related problems on functional status via mastery varied between 17.7% and 23.3%.Conclusions
Supporting OSA patients' sense of mastery may significantly contribute to better disease management. 相似文献9.

Background
Mobilisation of intensive care (ICU) patients attenuates ICU-acquired weakness, but the prevalence is low (12–54%). Better understanding of barriers and enablers may inform practice.Objectives
To identify barriers to mobilisation and factors associated with successful mobilisation in our medical /surgical /trauma ICU where mobilisation is well-established.Methods
4-week prospective study of frequency and intensity of mobilisation, clinical factors and barriers (extracted from electronic database). Generalized linear mixed models were used to describe associations between demographics, clinical factors and successful mobilisation.Results
202 patients accounted for 742 patient days. Patients mobilised on 51% of patient days. Most frequent barriers were drowsiness (18%), haemodynamic/respiratory contraindications (17%), and medical orders (14%). Predictors of successful mobilisation included high Glasgow Coma Score (OR = 1.44, 95%CI=[1.29–1.60]), and male sex (OR = 2.29, 95%CI=[1.40–3.75]) but not age (OR = 1.05, 95%CI=[1.01–1.08]).Conclusions
Our major barriers (drowsiness, haemodynamic/respiratory contraindications) may be unavoidable, indicating an upper limit of feasible mobilisation therapy in ICU. 相似文献10.

Background
In developing countries, the number of adults who develop myocardial infarction (MI) at a young age is high. The popularity of waterpipe smoking (WPS) has increased among the same age group. It is unknown if WPS contributes to the incidence of early-onset MI.Objective
To study the association of WPS with early-onset MI, which is defined as first MI occurring in individuals 18 ≥ age ≤ 45 years compared to those older than 45 years.Methods
This was a cross-sectional study. The association of WPS with first-time MI was compared between younger and older adults (N = 225).Results
Twenty-five percent of all participants developed an acute MI before the age of 46 years. Both cigarette and WPS were more common among younger first-time MI patients than older first-time MI patients.Conclusions
WPS is one risk factor that distinguishes the risk profile of young adults with early-onset MI. 相似文献11.

Background
Nationally-derived models predicting 30-day readmissions following heart failure (HF) hospitalizations yield insufficient discrimination for institutional use.Objective
Develop a customized readmission risk model from Medicare-employed and institutionally-customized risk factors and compare the performance against national models in a medical center.Methods
Medicare patients age ≥ 65 years hospitalized for HF (n = 1,454) were studied in a derivation cohort and in a separate validation cohort (n = 243). All 30-day hospital readmissions were documented. The primary outcome was risk discrimination (c-statistic) compared to national models.Results
A customized model demonstrated improved discrimination (c-statistic 0.72; 95% CI 0.69 – 0.74) compared to national models (c-statistics of 0.60 and 0.61) with a c-statistic of 0.63 in the validation cohort. Compared to national models, a customized model demonstrated superior readmission risk profiling by distinguishing a high-risk (38.3%) from a low-risk (9.4%) quartile.Conclusions
A customized model improved readmission risk discrimination from HF hospitalizations compared to national models. 相似文献12.

Background
Symptoms of anxiety, depression, and cognitive impairment are common in heart failure (HF) patients, but there are inconsistencies in the literature regarding their relationship and effects on exercise capacity.Objectives
The aim of this study was to explore the relationships between exercise capacity and anxiety, depression, and cognition in HF patients.Methods
This was a secondary analysis on the baseline data of the Italian subsample (n = 96) of HF patients enrolled in the HF-Wii study. Data was collected with the 6-minute walk test (6MWT), Hospital Anxiety and Depression Scale, and Montreal Cognitive Assessment.Results
The HF patients walked an average of 222 (SD 114) meters on the 6MWT. Patients exhibited clinically elevated anxiety (48%), depression (49%), and severe cognitive impairment (48%). Depression was independently associated with the distance walked on the 6MWT.Conclusions
The results of this study reinforced the role of depression in relation to exercise capacity and call for considering strategies to reduce depressive symptoms to improve outcomes of HF patients. 相似文献14.

Background
Studies addressing patients with type 2 myocardial infarction and myocardial injury, including the impact of using high-sensitivity (hs) cardiac troponin (cTn) assays on their incidence are needed.Methods
Ours is a prospective, observational US cohort study. Consecutive emergency department patients with serial cTnI measurements were studied. Outcomes included 180-day mortality and major adverse cardiac events, including 2-year follow-up for those with myonecrosis.Results
Among 1640 patients, using a contemporary cTnI assay, 30% (n = 497) had ≥1 cTnI >99th percentile, with 4.7% (n = 77), 8.5% (n = 140), and 17% (n = 280) classified as type 1 myocardial infarction, type 2 myocardial infarction, and myocardial injury, respectively. Compared with patients without myonecrosis, 180-day mortality was higher for type 2 myocardial infarction (4% vs 13%, P < .0001) (adjusted hazard ratio 2.7; 95% confidence interval, 1.6-4.8; P = .0005) and myocardial injury (4% vs 11%, P < .0001) (adjusted hazard ratio 1.8; 95% confidence interval, 1.1-3.0; P = .02), both with mortality >20% at 2 years. Predictors of 2-year mortality for type 2 myocardial infarction included age, congestive heart failure, and beta-blockers. Relative to the contemporary cTnI assay, hs-cTnI had less myonecrosis (30% vs 26%, P = .003) and acute myocardial infarction (13.2% vs 10.8%, P = .032), including fewer type 2 myocardial infarctions (8.5% vs 6.3, P = .01), with no difference in myocardial injury (17% vs 15%, P = .1).Conclusions
cTnI increases are encountered in approximately a third of patients, the majority due to nonatherothrombotic conditions. Compared with patients without myonecrosis, type 2 myocardial infarction and myocardial injury have worse short-term outcomes, with mortality rates >20% at 2 years. hs-cTnI assay does not lead to more myocardial injury or infarction. 相似文献15.

Background
There is no insomnia screening tool validated in intensive care unit (ICU) survivors.Objectives
To examine the validity of a single item from the PTSD checklist-Civilian version (PCL-C) to detect insomnia by Insomnia Severity Index (ISI)Methods
We performed a secondary analysis of data from a longitudinal investigation in 120 medical-surgical ICU survivors. At 1 year post-ICU, patients completed ISI, PCL-C, and Medical Short-Form 12 (SF-12) by telephone. A single PCL-C item rates difficulty initiating or maintaining sleep over the past month. We compared performance characteristics of this PCL-C item to ISI-defined insomnia (ISI ≥15).Results
A score of ≥3 on the PCL-C sleep item exhibited 91% sensitivity and 67% specificity for ISI-defined insomnia (ISI ≥ 15), and it demonstrated construct validity by correlation to related QOL indices.Conclusions
A single PCL-C sleep item score ≥ 3 is a reasonable screen to identify insomnia symptoms in ICU survivors. 相似文献16.

Background
African Americans with heart failure (HF) have the highest rates of depression among all ethnicities in the USA.Objectives
To compare the effects by race on depressive symptoms and topics discussed in the first clinic appointment after HF hospitalization.Methods
This study is a secondary analysis of data from a randomized clinical trial testing a patient group discussion of HF self-management with 93 Caucasians and 77 African Americans.Results
Reduction in depressive symptoms was significantly greater among African American patients within the intervention group (F = 3.99, p = .047) than controls. There were significant differences by race in four topics (dietitian referral, appointment date, help preparing discussion questions, and advice on worsening HF symptoms) concerning patient-physician discussions.Conclusion
The intervention showed greater effect in reducing depressive symptoms among African Americans than Caucasians. Preparing patients for discussions at physician appointments on diet, depressive symptoms, and HF symptoms is recommended. 相似文献17.

Background
Research findings on the value of nurse certification were based on subjective perceptions or biased by correlations of certification status and global clinical factors. In heart failure, the value of certification is unknown.Objectives
Examine the value of certification based nurses' decision-making.Methods
Cross-sectional study of nurses who completed heart failure clinical vignettes that reflected decision-making in clinical heart failure scenarios. Statistical tests included multivariable linear, logistic and proportional odds logistic regression models.Results
Of nurses (N = 605), 29.1% were heart failure certified, 35.0% were certified in another specialty/job role and 35.9% were not certified. In multivariable modeling, nurses certified in heart failure (versus not heart failure certified) had higher clinical vignette scores (p = 0.002), reflecting higher evidence-based decision making; nurses with another specialty/role certification (versus no certification) did not (p = 0.62).Conclusions
Heart failure certification, but not in other specialty/job roles was associated with decisions that reflected delivery of high-quality care. 相似文献18.

Background
Hyperactive autonomic nervous system (ANS) is among the postulated pathophysiologic mechanisms of takotsubo syndrome (TTS). Diabetes mellitus (DM) with its associated ANS peripheral neuropathy could exert a “protective” influence for the emergence of TTS.Methods
A patient-based meta-analysis of the data obtained from all patients presented individually was carried out, focusing on age, gender, and history of hypertension (HTN) and DM.Results
The prevalences of HTN and DM for all 2,342 patients, aged 61.1 ± 17.3, 85.1% female, were 37.4% and 9.5%, for patients ≥ 60 years old were 45.8% and 11.7%, and for patients ≥65 years old were 48.2% and 12.3%, correspondingly. The prevalence of DM in patients with TTS is less than half of the world's and USA's elderly populations.Conclusions
Prevalence of DM in patients with TTS is lower than in the general population, suggesting that DM, may have a “protective” effect for the emergence of TTS. 相似文献19.

Background
The relationship between physical heart failure (HF) symptoms and pathophysiological mechanisms is unclear.Objective
To quantify the relationship between plasma β-adrenergic receptor kinase-1 (βARK1) and physical symptoms among adults with HF.Methods
We performed a secondary analysis of data collected from two studies of adults with HF. Plasma βARK1 was quantified using an enzyme-linked immunosorbent assay. Physical symptoms were measured with the HF Somatic Perception Scale (HFSPS). Generalized linear modeling was used to quantify the relationship between βARK1 and HFSPS scores.Results
The average age (n = 94) was 54.5 ± 13.1 years, 76.6% were male, and a majority (83.0%) had Class III or IV HF. βARK1 was significantly associated with HFSPS scores (β = 0.22 ± 0.10, p = 0.038), adjusting for other predictors of physical symptoms (model R2 = 0.250, F(7, 70) = 3.34, p = 0.004).Conclusions
Higher βARK1 is associated with worse physical HF symptoms, pinpointing a potential pathophysiologic underpinning. 相似文献20.
