Hepatocellular carcinoma (HCC) is the fifth most common cancer with high mortality, due to late diagnosis and limited treatment options. Blood miRNAs, which circulate in a highly stable, cell-free form, show promise as novel potential biomarkers for early detection of HCC. Whole miRNome profiling was performed to identify deregulated miRNAs between HCC and normal healthy (NH) volunteers. These deregulated miRNAs were validated in an independent cohort of HCC, NH and chronic Hepatitis B (CHB) volunteers and finally in a 3
rd
cohort comprising NH, CHB, cirrhotic and HCC volunteers to evaluate miRNA changes during disease progression. The associations between circulating miRNAs and liver-damage markers, clinicopathological characteristics and survival outcomes were analysed to identify prognostic markers. Twelve miRNAs are differentially expressed between HCC and NH individuals in all three cohorts. Five upregulated miRNAs (miR-122-5p, miR-125b-5p, miR-885-5p, miR-100-5p and miR-148a-3p) in CHB, cirrhosis and HCC patients are potential biomarkers for CHB infection, while miR-34a-5p can be a biomarker for cirrhosis. Notably, four miRNAs (miR-1972, miR-193a-5p, miR-214-3p and miR-365a-3p) can distinguish HCC from other non-HCC individuals. Six miRNAs are potential prognostic markers for overall survival.
Background: The minimally invasive chevron-Akin (MICA) osteotomy is an increasingly popular technique for the correction of hallux valgus. However, there is a paucity of literature comparing it with traditional open techniques. The purpose of this study was to compare the clinical and radiological outcomes of the MICA osteotomy using a new-generation MICA screw and scarf-Akin osteotomy for hallux valgus correction. Methods: Thirty cases of MICA osteotomy were propensity score matched 1:1 with a control group of 30 scarf-Akin osteotomy cases. The groups were matched for age, sex, body mass index, preoperative visual analog scale (VAS) score, American Orthopaedic Foot & Ankle Society (AOFAS) metatarsophalangeal-interphalangeal (MTP-IP) score, 36-Item Short-Form Health Survey (SF-36) physical component score (PCS) and mental component score (MCS), preoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), and concomitant procedures. Outcomes were compared at 6 and 24 months postoperatively. Early postoperative VAS scores were also compared. Results: Both groups demonstrated significant improvements in VAS score, AOFAS score, and SF-36 PCS and MCS at 6 and 24 months postoperatively. For the MICA group, HVA improved from 23.5 to 7.7 degrees, and IMA improved from 13.5 to 7.5 degrees. For the scarf-Akin osteotomy group, HVA improved from 23.7 to 9.3 degrees, and IMA improved from 13.6 to 7.8 degrees. The first 24-hour postoperative VAS score was significantly lower in the MICA group compared with the scarf-Akin group (2.0 ± 2.0 vs 3.4 ± 2.6, P = .029). However, there was no significant difference in clinical or radiological outcomes between the groups at 6 and 24 months. Conclusion: The MICA procedure with the new-generation MICA screw is an attractive option for the correction of hallux valgus, yielding similar midterm radiological and clinical outcomes compared with the well-established scarf-Akin osteotomy. The first 24-hour postoperative VAS score in the MICA group was also statistically lower, although its clinical significance remains to be determined. Level of Evidence: Level III, retrospective comparative study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
