Liver frailty and all-cause mortality in the older participants of the Salus in Apulia Study

The liver contribution to the biological network underlying physical frailty in aging is underestimated. How best to measure this contribution magnitude and impact on health risk trajectories in frail individuals is not yet entirely clear. We analyzed the association of a novel liver frailty phenotype with the risk of death in older participants of the Salus in Apulia Study cohort. Clinical and physical examination, routine biomarkers, medical history, and anthropometry were analyzed in 1929 older adults (65?+). Physical frailty was classified by Cardiovascular Health Study criteria, and liver fibrosis risk by fibrosis-4 (FIB-4). The liver frailty phenotype was defined as physical frailty plus high-risk liver fibrosis (score?>?2.67). Physical frailty, high-risk liver fibrosis, and liver frailty subjects were compared to subjects without these conditions (non-frail). Proportional Cox regression tested the adjusted association between liver frailty and all-cause mortality for each category. The liver frailty prevalence was relatively low (3.8%), but higher in men (58.1%). Compared to non-frail older subjects, liver frailty subjects were significantly older (effect size (ES)???1.11, 95% confidence interval (CI)???1.35 to???0.87), with a lower education (ES 0.48, 95%CI 0.24 to 0.71) and higher multimorbidity (ES 15.81, 95%CI 4.20 to 27.41). Cox multivariate analyses showed a two-fold increased risk of overall mortality (hazard ratio 2.09, 95%CI 1.16–3.74) even after the adjustment for age, sex, education, and alcohol consumption. The liver frailty phenotype runs twice the risk of overall mortality compared with the non-frail population. This clinical tool, validated in a Southern Italian population, is based on simple sets of measures that can conveniently be assessed also in the primary care setting.

     

Mechanical valve prosthesis is a valid option for aortic valve replacement in the elderly

BACKGROUND AND AIM OF THE STUDY: Thromboembolism and hemorrhage related to anticoagulation remain a major concern in elderly patients with mechanical valves. Clinical results following isolated aortic valve replacement (AVR) with tilting disk and bileaflet prostheses in patients aged over 70 years were analyzed and compared with results in patients aged <45 years. METHODS: Between January 1980 and August 2002, 319 consecutive older patients (group A) and 497 young patients AVR. Preoperative clinical data, early and late mortality, valve-related complications and data related to anticoagulation status (including mean INR and mean interval between INR assays) were compared between groups. RESULTS: Hospital mortality was lower in group B (3.4%) than in group A (10.7%; p <0.0001). Twelve-year actuarial survival was lower in older patients (54% in group A versus 78% in group B; p <0.001). The two groups showed similar 12-year actuarial freedom from hemorrhage (99.6% versus 99.5%; p = 0.69), endocarditis (99.6% versus 98.43%; p = 0.25) and perivalvular leak (99.6% versus 97.9%; p = 0.21). However, actuarial freedom from thromboembolism was lower in older patients (98.8% versus 99.7%; p = 0.041). CONCLUSION: Despite lower rates of long-term mortality and thromboembolism (the latter because of advanced atherosclerosis) in group A, there were no differences in rates of other valve-related complications. Hence, older age cannot be considered a contraindication to implantation of mechanical valves in the aortic position.     

Time of catheter removal in candidemia and mortality

Background

The impact of central venous catheter (CVC) removal on the outcome of patients with candidemia is controversial, with studies reporting discrepant results depending on the time of CVC removal (early or any time during the course of candidemia).

Neutropenia as a Complication of Tumefactive Demyelinating Disease: A Case Report

Tumefactive demyelination is an aggressive, localized, generally solitary area of demyelination that often mimics a neoplasm. We present a case of a 13-year-old female patient who presented with sudden-onset progressive hemiplegia and hemianopsia. Magnetic resonance imaging of the brain showed tumefactive demyelination with partial rim of enhancement. During inpatient rehabilitation, she developed myalgias, rash, and abdominal and mouth pain with evidence for severe neutropenia. The neutropenia was determined to be a secondary complication of the tumefactive disease process. This scenario may be concerning in an inpatient rehabilitation setting, as patients share common areas, increasing the risk of acquired infection while neutropenic.

Cross-cultural adaptation to Brazilian Portuguese of the Activity Measure for Post-Acute Care (AM-PAC) short forms for outpatients in rehabilitation

Background

The Activity Measure for Post-Acute Care was developed to evaluate the limitations of activities of adult individuals with different health conditions.

Advanced Practice Registered Nurse–directed Care Coordination Interventions and Outreach After Critical Illness

The purpose of this pilot study was to implement care collaboration measures into a critical care advanced practice. The intervention included an outreach algorithm and a standardized handoff tool during care transition. One hundred eight patients were enrolled; 5 (4%) experienced unplanned readmission. There was no significant association with transition time and the ability to complete the algorithm. Comorbidities of chronic obstructive pulmonary disease (P < .005), a PaO₂ ratio < 200 (P < .003), and pulmonary disease (P < .027) showed increased unplanned readmission within 48 hours of transition. Implementing critical care collaborating measures was not affected by transition time and unit care flow.
