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.

     

Comparing the efficacy and safety of fixed versus weight-based dosing of epoetin alpha in anemic cancer patients receiving platinum-based chemotherapy

Fixed dosing is potentially more convenient than weight-based dosing for both patients and physicians. Therefore, this open-label, randomized (1:1), multicenter study was conducted to compare the effectiveness, safety, and quality-of-life benefits of fixed vs. weight-based dosing of epoetin alpha in anemic cancer patients undergoing chemotherapy. Five hundred forty-six anemic patients undergoing platinum-based chemotherapy for solid malignancies were enrolled. Patients received epoetin alpha, either a fixed dose of 10,000 IU or a weight-based dose of 150 IU/kg, administered subcutaneously 3 times weekly for up to 12 weeks. Endpoints were transfusion requirements over days 29-84, change in hemoglobin (Hb) level from baseline, and change in quality-of-life (QOL) scores from baseline as measured using the Cancer Linear Analog Scale (CLAS). Five hundred and thirty-two patients received at least 1 dose of epoetin alpha, and 510 of these (255 in each treatment group) were considered evaluable for efficacy. At day 84, rates for freedom from transfusion were similar between the fixed-dose and the weight-based dose group (84% vs. 87%, respectively, p=0.32), as calculated by the lifetable method. These rates were also similar between patients in the 45-63 kg weight group receiving the fixed 10,000 IU dose or 7,000-9,000 IU on a per-weight basis (83% vs. 87%, respectively), and those in the 70-100 kg weight group receiving the fixed 10,000 IU dose or 11,000-15,000 IU on a per-weight basis (85% vs. 83%, respectively). Mean Hb increases from baseline to last observation were 2.10 g/dl [95% confidence intervals (CI95) 1.85-2.35] in the 10,000 IU group (from 9.64-11.74 g/dl) and 2.06 g/dl (CI95 1.82-2.30) in the 150 IU/kg group (from 9.70-11.76 g/dl). QOL results were similar for both groups and cumulative data have been reported. For 275 patients (in both groups combined) with CLAS QOL scores both at baseline and 29-98 days thereafter, the QOL index (average of scores for the 3 QOL parameters: energy level, ability to do daily activities and overall QOL) increased by 10.4 mm (CI95 7.5-13.2), from 46.2 mm at baseline to 56.6 mm at the final observation. QOL improvements were directly associated with Hb increases (p<0.001, multiple linear regression analysis) within all chemotherapy response classes. Epoetin alpha was well tolerated in both groups. Fixed (10,000 IU) and weight-based (150 IU/kg) dosing regimens of epoetin alpha demonstrated similar efficacy in maintaining freedom from transfusion, increasing Hb levels, and improving QOL in anemic cancer patients undergoing platinum-based chemotherapy. QOL improvements were directly associated with Hb increases. These findings support the use of a fixed-dose regimen of epoetin alpha, which may offer greater convenience for physicians and patients than weight-based dosing with this agent.     

The middle school mentoring program in allied health: a proposed model

This article describes the efforts of one group of participants in the Coalition for Allied Health Leadership program. Their purpose was to design a mentoring program for middle school students that will increase their awareness of the allied health professions as viable career options. A rationale for such a program and a program structure are provided as a beginning point for increasing awareness of allied health careers.     

Educational programs in radiologic technology

This article reports on a survey of educational programs in radiography, nuclear medicine, radiation therapy and sonography. The purpose of the survey was to help educators validate their individual program requirements by providing a profile of educational programs in each discipline. Survey results demonstrate similarities in program length, academic system, faculty teaching load and enrollment size. Major differences were found in clinical hour requirements and credit hour conversion.     

Mediterranean Diet and Fatty Liver Risk in a Population of Overweight Older Italians: A Propensity Score-Matched Case-Cohort Study

Hepatic steatosis, often known as fatty liver, is the most common hepatic disease in Western countries. The latest guidelines for the treatment of nonalcoholic fatty liver disease emphasize lifestyle measures, such as changing unhealthy eating patterns. Using a propensity score-matching approach, this study investigated the effect of adhering to a Mediterranean diet (MedDiet) on fatty liver risk in an older population (≥65 years) from Southern Italy. We recruited 1.403 subjects (53.6% men, ≥65 years) who completed a food frequency questionnaire (FFQ) and underwent clinical assessment between 2015 and 2018. For the assessment of the liver fat content, we applied the Fatty Liver Index (FLI). To evaluate the treatment effect of the MedDiet, propensity score matching was performed on patients with and without FLI > 60. After propensity score-matching with the MedDiet pattern as treatment, we found a higher consumption of red meat (p = 0.04) and wine (p = 0.04) in subjects with FLI > 60. Based on the FLI, the inverse association shown between adherence to the MedDiet and the risk of hepatic steatosis shows that the MedDiet can help to prevent hepatic steatosis. Consuming less red and processed meat, as well as alcoholic beverages, may be part of these healthy lifestyle recommendations.     

Platelet number is negatively and independently associated with carotid intima-media thickness in apparently healthy overweight/obese subjects

Background and Aim

A significant change of platelet number may be a risk factor for atherosclerotic cardiovascular disease. The aim of this study was to investigate the association between platelet number and early signs of atherosclerosis, evaluated by carotid intima-media thickness (c-IMT), in a apparently healthy population mainly represented by obese subjects.

Platelet number is positively and independently associated with glycated hemoglobin in non-diabetic overweight and obese subjects

Background and aims

A significant increase in platelet count may be a risk factor for atherosclerotic cardiovascular disease. This study investigates the association between platelet number and glucose metabolism, evaluated by glycated hemoglobin (HbA1c) levels, in a apparently healthy population represented by overweight and obese subjects with normal glucose and HbA1c levels.
