Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is a multi-system disease that not only affects the structure and function of the liver but also increases the incidence of type 2 diabetes, cardiovascular disease (CVD), cerebrovascular disease, and chronic kidney disease. In 2020, experts reached a consensus to recommend a more appropriate term to more accurately and positively define fatty liver disease associated with metabolic disorders, namely, metabolic dysfunction-associated fatty liver disease (MAFLD). The aim of this study was to investigate the risk of CVD incidence or CVD mortality in patients diagnosed with MAFLD. This study is a meta-analysis of ten cohort studies. Results show that patients in the MAFLD group had a significantly increased relative risk of CVD or death from CVD during the follow-up compared with the control group. Authors conclude that even though there is a positive association between MAFLD and the risk of CVD or death from CVD, further studies are needed to demonstrate different effects of the newly defined MAFLD on CVD compared with previous NAFLD.
Abstract
BACKGROUND Metabolic dysfunction-associated fatty liver disease [MAFLD, formerly known as nonalcoholic fatty liver disease (NAFLD)] is one of the most important causes of liver disease worldwide, while cardiovascular disease (CVD) is still one of the main causes of morbidity and mortality worldwide, and the two are closely related. This study aimed to investigate the risk of CVD incidence or CVD-related mortality (CVD mortality) in patients diagnosed with MAFLD under new concepts and new diagnostic criteria. METHODS We searched English databases PubMed, Web of Science, Embase, and Cochrane Library for relevant literature. The language was restricted to English. RESULTS By 22 January 2022, 556 published studies were obtained through preliminary retrieval, and 10 cohort studies were included in this study. All statistical analyses were performed using Review Manager 5.2 software. Compared with the control group, patients in the MAFLD group had a significantly higher relative risk of CVD incidence or CVD mortality during the follow-up, with an RR rate of 1.95 (95% CI 1.76-2.17, p < 0.01). The incidence of CVD in the MAFLD group was more than twice that in the control group (RR 2.26, 95% CI 2.00-2.54, p < 0.01). The mortality rate of CVD was 1.57 times higher than that in the control group (RR 1.57, 95% CI 1.42-1.72, p < 0.01). CONCLUSIONS Patients diagnosed with MAFLD alone had higher cardiovascular mortality than those diagnosed with NAFLD alone based on the available data.

Plain language summary
Beta glucans, β-1,3-glucans (glucans) are chains of sugars (polysaccharides) naturally occurring in the cell walls of plants such as cereals, bacteria and fungi. They are gaining attention not only as an important food supplement but also as an immunostimulant and potential drug. It has been known since prehistoric times that mushrooms have medicinal properties. Glucans effect various branches of the immune system and there are numerous animal and human studies showing remarkable activity against a wide variety of tumours. This paper represents an up-to-date review of glucans and their role in various immune reactions and the treatment of cancer. It also cites studies showing their potential use for wound healing and skin health, chronic respiratory problems in children, alleviation of allergic problems and reducing cholesterol levels. Additional lesser-known effects of glucan include improvements in colitis, obesity, or Lyme disease The authors conclude that glucans are an important immunomodulator. They believe that glucans will soon move from food supplement to widely accepted drug.
Abstract
Glucans are part of a group of biologically active natural molecules and are steadily gaining strong attention not only as an important food supplement, but also as an immunostimulant and potential drug. This paper represents an up-to-date review of glucans (β-1,3-glucans) and their role in various immune reactions and the treatment of cancer. With more than 80 clinical trials evaluating their biological effects, the question is not if glucans will move from food supplement to widely accepted drug, but how soon.
