The silent burden of non-alcoholic fatty liver disease in the elderly: A global burden of disease analysis.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) represents a significant health threat worldwide. The growing trend towards an aging population, along with an alarming rise in obesity and diabetes, may have significant implications for the burden of NAFLD. AIM: To assess the impact of NAFLD on the elderly. METHODS: We utilised data from the Global Burden of Disease study between 2010 and 2019 to conduct a comprehensive analysis of the prevalence, mortality, and disability-adjusted life years (DALYs) associated with NAFLD in the elderly (65-89 years), stratified by region, nation, sociodemographic Index and sex. RESULTS: Globally, there were an estimated 228 million cases, 87,230 deaths and 1.46 million DALYs attributed to NAFLD in the elderly. Geographically, the Western Pacific region had the highest burden of NAFLD in the elderly. From 2010 to 2019, there was an increasing prevalence rate in all areas, with the most pronounced change observed in the Western Pacific region (annual percentage change (APC) +0.95%, p < 0.001). Over the study period, there was a more rapid increase in NAFLD prevalence in men (APC +0.74%, p < 0.001) than in women (APC +0.63%, p < 0.001). In most regions, death and DALYs rates have declined, with the exception of the Americas, where there was a slight increase (APC +0.25%, p = 0.002 and 0.38%, p < 0.001, respectively). CONCLUSION: Over the past decade, the burden of NAFLD in the elderly has been increasing, necessitating immediate and inclusive measures to tackle the rising burden.

The global burden of metabolic disease: Data from 2000 to 2019.

Global estimates of prevalence, deaths, and disability-adjusted life years (DALYs) from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 were examined for metabolic diseases (type 2 diabetes mellitus [T2DM], hypertension, and non-alcoholic fatty liver disease [NAFLD]). For metabolic risk factors (hyperlipidemia and obesity), estimates were limited to mortality and DALYs. From 2000 to 2019, prevalence rates increased for all metabolic diseases, with the greatest increase in high socio-demographic index (SDI) countries. Mortality rates decreased over time in hyperlipidemia, hypertension, and NAFLD, but not in T2DM and obesity. The highest mortality was found in the World Health Organization Eastern Mediterranean region, and low to low-middle SDI countries. The global prevalence of metabolic diseases has risen over the past two decades regardless of SDI. Urgent attention is needed to address the unchanging mortality rates attributed to metabolic disease and the entrenched sex-regional-socioeconomic disparities in mortality.

Leptin alters energy intake and fat mass but not energy expenditure in lean subjects.

Based on studies in mice, leptin was expected to decrease body weight in obese individuals. However, the majority of the obese are hyperleptinemic and do not respond to leptin treatment, suggesting the presence of leptin tolerance and questioning the role of leptin as regulator of energy balance in humans. We thus performed detailed novel measurements and analyses of samples and data from our clinical trials biobank to investigate leptin effects on mechanisms of weight regulation in lean normo- and mildly hypo-leptinemic individuals without genetic disorders. We demonstrate that short-term leptin administration alters food intake during refeeding after fasting, whereas long-term leptin treatment reduces fat mass and body weight, and transiently alters circulating free fatty acids in lean mildly hypoleptinemic individuals. Leptin levels before treatment initiation and leptin dose do not predict the observed weight loss in lean individuals suggesting a saturable effect of leptin. In contrast to data from animal studies, leptin treatment does not affect energy expenditure, lipid utilization, SNS activity, heart rate, blood pressure or lean body mass.

The rise of biosimilars: How they got here and where they are going.

Biosimilars have become a subject of great interest in the past few years. The European Union and the United States are seeing an increasing number of biosimilar applications and approvals. The development of a biosimilar is significantly more complex and costly than a small molecule generic product. In the European Union, there has been a wider use of these medications compared to the United States. More biosimilars are gaining approval in the United States, and these products will likely alter the healthcare system in highly impactful ways. Understanding the regulatory process, the risks, and benefits will enable clinicians to be prepared and maximize the utility of these medications when they enter the market. This article introduces the concept of a biosimilar, discusses the regulatory process in the United States, and reviews the risks and benefits of these products.
