In contrast, neither of the ruminant-derived TFAs (C161n-7t and C181n-7t) suggested any inverse correlations with all-cause death, mortality due to heart disease, cancer or other causes. The major isomer of industrial TFAs, the higher circulating C181n-9t might be associated with increased long-term mortality. The associations with death risk turned slight with the reduction of TFAs consumption by half. However, dietary guidelines should rigorously identify the healthy effect of animal TFAs consumption.

Our purpose was to analyze influence of sarcopenia on overall survival (OS) in patients with malignant hematological diseases (MHD) based on a large sample. MEDLINE, EMBASE, and SCOPUS databases were screened for associations between sarcopenia and OS in MHD up to December 2019. Overall, 7 studies met the inclusion criteria. The methodological quality of the involved studies was checked according to the QUADAS instrument. The meta-analysis was undertaken using RevMan 5.3 software. The included 7 studies comprised 1578 patients. There were different MHD diffuse large B cell lymphoma (DLBCL, 4 studies, 573 patients, 36.3%), acute leukemias and/or myelodysplastic syndrome (2 studies, 949 patients, 60.1%), and multiple myeloma (one study, 56 patients, 3.6%). Sarcopenia identified on CT examinations was reported in 617 patients (39.1%, range, 24.6%-66.1%). In the overall sample, showed that sarcopenia was associated with lower OS (simple regression HR 2.15, CI 95% 1.42-3.25, p<0.0003; multiple regression HR=1.94, CI 95% 1.30-2.90, p<0.001). Furth
