Defining comprehensive models of care for NAFLD

Non-alcoholic fatty liver disease (NAFLD) is now the leading cause of chronic liver disease globally. Despite the increased demand placed on health-care systems, little attention has been given to the design and implementation of efficient and effective models of care for patients with NAFLD. In many health-care settings, no formal pathways exist and, where pathways are in place, they are often not standardized according to good practices. We systematically searched the peer-reviewed literature with the aim of identifying published examples of comprehensive models of care that answered four key questions: what services are provided? Where are they provided? Who is offering them? How are they coordinated and integrated within health-care systems? We identified seven models of care and synthesized the findings into eight recommendations nested within the ‘what, where, who and how’ of care models. These recommendations, aimed at policy-makers and practitioners designing and implementing models of care, can help to address the increasing need for the provision of good practice care for patients with NAFLD

A cross-sectional study of the public health response to non-alcoholic fatty liver disease in Europe

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) is a growing public health problem worldwide and has become an important field of biomedical inquiry. We aimed to determine whether European countries have mounted an adequate public health response to NAFLD and non-alcoholic steatohepatitis (NASH). Methods: In 2018 and 2019, NAFLD experts in 29 European countries completed an English-language survey on policies, guidelines, awareness, monitoring, diagnosis and clinical assessment in their country. The data were compiled, quality checked against existing official documents and reported descriptively. Results: None of the 29 participating countries had written strategies or action plans for NAFLD. Two countries (7%) had mentions of NAFLD or NASH in related existing strategies (obesity and alcohol). Ten (34%) reported having national clinical guidelines specifically addressing NAFLD and, upon diagnosis, all included recommendations for the assessment of diabetes and liver cirrhosis. Eleven countries (38%) recommended screening for NAFLD in all patients with either diabetes, obesity and/or metabolic syndrome. Five countries (17%) had referral algorithms for follow-up and specialist referral in primary care, and 7 (24%) reported structured lifestyle programmes aimed at NAFLD. Seven (24%) had funded awareness campaigns that specifically included prevention of liver disease. Four countries (14%) reported having civil society groups which address NAFLD and 3 countries (10%) had national registries that include NAFLD. Conclusions: We found that a comprehensive public health response to NAFLD is lacking in the surveyed European countries. This includes policy in the form of a strategy, clinical guidelines, awareness campaigns, civil society involvement, and health systems organisation, including registries. Lay summary: We conducted a survey on non-alcoholic fatty liver disease with experts in European countries, coupled with data extracted from official documents on policies, clinical guidelines, awareness, and monitoring. We found a general lack of national policies, awareness campaigns and civil society involvement, and few epidemiological registries

Body composition and body fat distribution are related to cardiac autonomic control in non-alcoholic fatty liver disease patients

BACKGROUND/OBJECTIVES: Heart rate recovery (HRR), a cardiac autonomic control marker, was shown to be related to body composition (BC), yet this was not tested in non-alcoholic fatty liver disease (NAFLD) patients. The aim of this study was to determine if, and to what extent, markers of BC and body fat (BF) distribution are related to cardiac autonomic control in NAFLD patients. SUBJECTS/METHODS: BC was assessed with dual-energy X-ray absorptiometry in 28 NAFLD patients (19 men, 51±13 years, and 9 women, 47±13 years). BF depots ratios were calculated to assess BF distribution. Subjects’ HRR was recorded 1 (HRR1) and 2 min (HRR2) immediately after a maximum graded exercise test. RESULTS: BC and BF distribution were related to HRR; particularly weight, trunk BF and trunk BF-to-appendicular BF ratio showed a negative relation with HRR1 (r 1⁄4 0.613, r 1⁄4 0.597 and r 1⁄4 0.547, respectively, Po0.01) and HRR2 (r 1⁄4 0.484, r 1⁄4 0.446, Po0.05, and r 1⁄4 0.590, Po0.01, respectively). Age seems to be related to both HRR1 and HRR2 except when controlled for BF distribution. The preferred model in multiple regression should include trunk BF-to-appendicular BF ratio and BF to predict HRR1 (r2 1⁄4 0.549; Po0.05), and trunk BF-to-appendicular BF ratio alone to predict HRR2 (r2 1⁄4 0.430; Po0.001). CONCLUSIONS: BC and BF distribution were related to HRR in NAFLD patients. Trunk BF-to-appendicular BF ratio was the best independent predictor of HRR and therefore may be best related to cardiovascular increased risk, and possibly act as a mediator in age-related cardiac autonomic control variation.info:eu-repo/semantics/publishedVersio

The SCottish Alcoholic Liver disease Evaluation: a population-level matched cohort study of hospital-based costs, 1991-2011

Studies assessing the costs of alcoholic liver disease are lacking. We aimed to calculate the costs of hospitalisations before and after diagnosis compared to population controls matched by age, sex and socio-economic deprivation. We aimed to use population level data to identify a cohort of individuals hospitalised for the first time with alcoholic liver disease in Scotland between 1991 and 2011.Incident cases were classified by disease severity, sex, age group, socio-economic deprivation and year of index admission. 5 matched controls for every incident case were identified from the Scottish population level primary care database. Hospital costs were calculated for both cases and controls using length of stay from morbidity records and hospital-specific daily rates by specialty. Remaining lifetime costs were estimated using parametric survival models and predicted annual costs. 35,208 incident alcoholic liver disease hospitalisations were identified. Mean annual hospital costs for cases were 2.3 times that of controls pre diagnosis (£804 higher) and 10.2 times (£12,774 higher) post diagnosis. Mean incident admission cost was £6,663. Remaining lifetime cost for a male, 50-59 years old, living in the most deprived area diagnosed with acoholic liver disease was estimated to be £65,999 higher than the matched controls (£12,474 for 7.43 years remaining life compared to £1,224 for 21.8 years). In Scotland, alcoholic liver disease diagnosis is associated with significant increases in admissions to hospital both before and after diagnosis. Our results provide robust population level estimates of costs of alcoholic liver disease for the purposes of health-care delivery, planning and future cost-effectiveness analyses

Implantation of ICD and CRT-D in the elderly population : will it be a limiting factor?

Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2017Introduction: Implantable cardioverter defibrillator (ICD) and cardiac resynchronization (CRT-D) implantation in elderly patients is effective in preventing sudden death, although limited by the natural shorter life expectancy. The different device brands present very variable survival estimates and it has been discussed the availability of less expensive, less longevity generators for the elderly population. Purpose: To determine if the expected survival rate in the elderly patient population (≥75 years) should influence the selection of the desired longevity of the devices. Methods: A retrospective single-center study of consecutive patients who underwent implantation of ICD or CRT-D after November 1995. The mean survival of patients undergoing 1st implant or generator replacement at an advanced age (≥75 years) was evaluated and compared to the effective longevity of the generators. Cumulative survival analyzes using the Kaplan Meier method were used. Results: A total of 1312 cardiac devices were implanted, of which 163 generators in elderly patients (53% CDI and 47% CRT-D). Of these, 77% corresponded to the 1st implant. The median survival after implantation of the elderly patients was 6.8 years, not differing according to the type of device (Log-rank P = NS). The median longevity of CDI generators was 6.9 years, in line with the expected survival of elderly patients. Conversely, the median CRT-D longevity was 5.8 years, lower than the average survival of the elderly. For this reason, 21% of these CRT-D carriers were subsequently subjected to generator replacement, due to battery exhaustion. Conclusion: The effective longevity of ICDs is in agreement with an expected survival of elderly patients, for which it will not make sense to provide generators of shortened longevity for this population. The effective longevity of the CRTs is lower than the survival expectancy of the treatments, so that, paradoxically, generators with increased longevity should be favored.info:eu-repo/semantics/publishedVersio

Recent advances in alcohol-related liver disease (ALD): summary of a Gut roundtable meeting

Alcohol-related liver disease (ALD), which includes a range of disorders of different severity and is one of the most prevalent types of liver disease worldwide, has recently regained increased attention. Among other reasons, the realisation that any alcohol intake, regardless of type of beverage represents a health risk, and the new therapeutic strategies tested in recently published or undergoing clinical trials spur scientific interest in this area. In April 2019, Gut convened a round table panel of experts during the European Association for the Study of the Liver (EASL) International Liver Congress (ILC) in Vienna to discuss critical and up-to-date issues and clinical trial data regarding ALD, its epidemiology, diagnosis, management, pathomechanisms, possible future treatments and prevention. This paper summarises the discussion and its conclusions

Role of lipid-mobilising factor (LMF) in protecting tumour cells from oxidative damage

Lipid-mobilising factor (LMF) is produced by cachexia-inducing tumours and is involved in the degradation of adipose tissue, with increased oxidation of the released fatty acids through an induction of uncoupling protein (UCP) expression. Since UCP-2 is thought to be involved in the detoxification of free radicals if LMF induced UCP-2 expression in tumour cells, it might attenuate free radical toxicity. As a model system we have used MAC13 tumour cells, which do not produce LMF. Addition of LMF caused a concentration-dependent increase in UCP-2 expression, as determined by immunoblotting. This effect was attenuated by the β3 antagonist SR59230A, suggesting that it was mediated through a β3 adrenoreceptor. Co-incubation of LMF with MAC13 cells reduced the growth-inhibitory effects of bleomycin, paraquat and hydrogen peroxide, known to be free radical generators, but not chlorambucil, an alkylating agent. There was no effect of LMF alone on cellular proliferation. These results indicate that LMF antagonises the antiproliferative effect of agents working through a free radical mechanism, and may partly explain the unresponsiveness to the chemotherapy of cachexia-inducing tumours. © 2004 Cancer Research UK
