A global survey on the use of the international classification of diseases codes for metabolic dysfunction-associated fatty liver disease.

BACKGROUND: With the implementation of the 11th edition of the International Classification of Diseases (ICD-11) and the publication of the metabolic dysfunction-associated fatty liver disease (MAFLD) nomenclature in 2020, it is important to establish consensus for the coding of MAFLD in ICD-11. This will inform subsequent revisions of ICD-11. METHODS: Using the Qualtrics XM and WJX platforms, questionnaires were sent online to MAFLD-ICD-11 coding collaborators, authors of papers, and relevant association members. RESULTS: A total of 890 international experts in various fields from 61 countries responded to the survey. We also achieved full coverage of provincial-level administrative regions in China. 77.1% of respondents agreed that MAFLD should be represented in ICD-11 by updating NAFLD, with no significant regional differences (77.3% in Asia and 76.6% in non-Asia, p = 0.819). Over 80% of respondents agreed or somewhat agreed with the need to assign specific codes for progressive stages of MAFLD (i.e. steatohepatitis) (92.2%), MAFLD combined with comorbidities (84.1%), or MAFLD subtypes (i.e., lean, overweight/obese, and diabetic) (86.1%). CONCLUSIONS: This global survey by a collaborative panel of clinical, coding, health management and policy experts, indicates agreement that MAFLD should be coded in ICD-11. The data serves as a foundation for corresponding adjustments in the ICD-11 revision.

TRIANGLE operation, combined with adequate adjuvant chemotherapy, can improve the prognosis of pancreatic head cancer: A retrospective study.

BACKGROUND: The TRIANGLE operation involves the removal of all tissues within the triangle bounded by the portal vein-superior mesenteric vein, celiac axis-common hepatic artery, and superior mesenteric artery to improve patient prognosis. Although previously promising in patients with locally advanced pancreatic ductal adenocarcinoma (PDAC), data are limited regarding the long-term oncological outcomes of the TRIANGLE operation among resectable PDAC patients undergoing pancreaticoduodenectomy (PD). AIM: To evaluate the safety of the TRIANGLE operation during PD and the prognosis in patients with resectable PDAC. METHODS: This retrospective cohort study included patients who underwent PD for pancreatic head cancer between January 2017 and April 2023, with or without the TRIANGLE operation. Patients were divided into the PDTRIANGLE and PDnon-TRIANGLE groups. Surgical and survival outcomes were compared between the two groups. Adequate adjuvant chemotherapy was defined as adjuvant chemotherapy ≥ 6 months. RESULTS: The PDTRIANGLE and PDnon-TRIANGLE groups included 52 and 55 patients, respectively. There were no significant differences in the baseline characteristics or perioperative indexes between the two groups. Furthermore, the recurrence rate was lower in the PDTRIANGLE group than in the PDnon-TRIANGLE group (48.1% vs 81.8%, P < 0.001), and the local recurrence rate of PDAC decreased from 37.8% to 16.0%. Multivariate Cox regression analysis revealed that PDTRIANGLE (HR = 0.424; 95%CI: 0.256-0.702; P = 0.001), adequate adjuvant chemotherapy ≥ 6 months (HR = 0.370; 95%CI: 0.222-0.618; P < 0.001) and margin status (HR = 2.255; 95%CI: 1.252-4.064; P = 0.007) were found to be independent factors for the recurrence rate. CONCLUSION: The TRIANGLE operation is safe for PDAC patients undergoing PD. Moreover, it reduces the local recurrence rate of PDAC and may improve survival in patients who receive adequate adjuvant chemotherapy.

Blood Immune Cell Composition Associated with Obesity and Drug Repositioning Revealed by Epigenetic and Transcriptomic Conjoint Analysis.

This research was designed to analyze the composition of immune cells in obesity and identify novel and potent drugs for obesity management by epigenetic and transcriptomic conjoint analysis. DNA methylation data set (GSE166611) and mRNA expression microarray (GSE18897) were obtained from the Gene Expression Omnibus database. A total of 72 objects (35 obese samples and 37 controls) were included in the study. Immune cell composition analysis, drug repositioning, and gene set enrichment analysis (GSEA) were performed using CIBERSORT, connectivity map (CMap), and GSEA tools. Besides, we performed a single-cell RNA-seq of the immune cells from whole blood samples obtained from one obese patient and one healthy control. mRNA levels of drug target genes were analyzed by qPCR assay in blood samples from six patients and six healthy controls. Immune cell composition analysis found that CD8 + T cells and NK cells were significantly lower in the obese group. 11 drugs/compounds are considered to possess obesity-control potential, such as atorvastatin. Moreover, the expression of drug targets (STAT3, MCL1, PMAIP1, SOD2, FOX O 3, FOS, FKBP5) in obese patients were higher than those in controls. In conclusion, immune cells are potential therapeutic targets for obesity. Our results also contribute to accelerate research on drug development of obesity.

Prothymosin α promotes colorectal carcinoma chemoresistance through inducing lipid droplet accumulation.

Colorectal cancer (CRC) affects millions of people worldwide. Chemoresistance seriously impairs the therapeutic effects. Lipid droplets (LDs) abnormally accumulate in CRC supported chemoresistance. Exploring the mechanism of LD-induced chemoresistance is extremely important for improving prognosis of CRC patients. The expression of PTMA was increased in both CRC tissues and cells, which was positively correlated with LD production. PTMA facilitated chemoresistance to gemcitabine by inducing LD production in CRC cells. PTMA enhanced LD biogenesis and chemoresistance to gemcitabine by promoting SREBP-1-mediated lipogenesis and STAT3 activation in CRC.

Long-term outcomes of Roux-en-Y gastric bypass versus medical therapy for patients with type 2 diabetes: a meta-analysis of randomized controlled trials.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) has been widely used for type 2 diabetes (T2D) patients with overweight or obesity. However, the long-term outcomes of RYGB versus medical therapy have not been well compared. OBJECTIVES: To evaluate the long-term outcomes of RYGB versus medical therapy for patients with T2D. SETTING: University-affiliated hospital, China. METHODS: Four electronic databases-PubMed, EMBASE, the Cochrane Library, and ClinicalTrials.gov-were searched for articles published through February 2021. Eligible studies were randomized controlled trials. RESULTS: Of 7 randomized controlled trials (15 articles), 477 patients were included: 239 were randomly divided into RYGB groups and 238 to medical therapy groups. Statistically higher rates of T2D remission were observed in RYGB groups at 1 year (relative risk [RR], 18.01; 95% confidence interval [CI], 4.53- 71.70; P < .0001), 3 years (RR, 29.58; 95% CI, 5.92-147.82; P < .0001), and 5 years (RR, 16.92; 95% CI, 4.15-69.00; P < .0001). Meanwhile, statistically higher rates of achieving the American Diabetes Association's (ADA's) treatment goal were observed in RYGB groups at 1 year (RR, 3.99; 95% CI, 1.01-15.82; P = .05), 2 years (RR, 2.98; 95% CI, 1.62- 5.48; P = .0004), 3 years (RR, 3.16; 95% CI, 1.33-7.49; P = .009), and 5 years (RR, 6.18; 95% CI, 1.69-22.68; P = .006). CONCLUSION: This meta-analysis indicated that RYGB led to higher rates of T2D remission than medical therapy at 1, 3, and 5 years, as well as higher rates of achieving ADA's composite goal at 1, 2, 3, and 5 years.

Effects of bariatric surgery on incidence of obesity-related cancers: a meta-analysis.

BACKGROUND: The aim of this meta-analysis was to investigate possible relationships between bariatric surgery and incidence of obesity-related cancers. Obesity is an established risk factor for obesity-related cancers but the effects of bariatric surgery on incidence of obesity-related cancers are uncertain. MATERIAL/METHODS: We searched 4 electronic databases to identify eligible studies: PubMed, Embase, Web of Science, and Google Scholar. Five observational studies were eligible and included in this meta-analysis. Random-effects or fixed-effects odds ratio (OR) and its corresponding 95% confidence interval (CI) were pooled. RESULTS: Meta-analysis of these 5 observational studies revealed that bariatric surgery was associated with a significantly (p=0.0004) reduced incidence of obesity-related cancers (OR=0.43, 95%CI, 0.27-0.69) when compared with control individuals. Pooled estimated data showed that bariatric surgery is associated with a 24% lower colorectal cancer (CRC) risk. No publication bias was detected by Egger's or Begg's tests. CONCLUSIONS: Although bariatric surgery may significantly reduce incidence of obesity-related cancers, considering the limitations of these included studies, these findings should be confirmed by further well-designed studies.

High-intensity focused ultrasound treatment for patients with unresectable pancreatic cancer.

BACKGROUND: High-intensity focused ultrasound (HIFU) is a non-invasive method of solid tissue ablation therapy. However, only a few studies have reported the effect of HIFU for unresectable pancreatic cancer. This study aimed to evaluate the clinical benefits, survival time and complications associated with the use of HIFU ablation in patients with unresectable pancreatic cancer. METHODS: Twenty-five patients with unresectable pancreatic cancer were enrolled in our study. All patients received HIFU therapy for tumors at least once. The therapeutic effects of HIFU was evaluated in terms of Karnofsky performance status (KPS) scores, pain relief, serum CA19-9, and imaging by B-US and CT before and after the therapy. We also recorded median overall survival time and complications caused by the treatment. RESULTS: In the 25 patients, KPS scores were above 60, and increased KPS was observed in 23 patients after treatment. Pain relief occurred in 23 patients. Serum CA19-9 levels were significantly reduced one month after HIFU treatment and became negative in 5 patients. B-US revealed enhanced tumor echogenicity in 13 patients and decreased tumor blood supply in 9. Tumor necrosis was confirmed by CT in 8 patients one month after HIFU treatment. The median overall survival time was 10 months, and the 1-year survival rate was 42%. No severe complications were observed after HIFU treatment. CONCLUSION: HIFU can effectively relieve pain, increase KPS, decrease tumor growth and prolong the survival time of patients with unresectable pancreatic cancer.

[Mechanism research progress of bariatric surgery for type 2 diabetes mellitus].

Patients with type 2 diabetes mellitus experience a complete and comfirm diabetic remission after bariatric surgery. Although weight-loss, reduction of food intake and other factors may play important roles in diabetic resolution after bariatric surgery, the major mechanism is the change in gastrointestinal hormones. Further research is essential to better understand these mechanisms and bariatric surgery may ultimately become a major tool in the treatment of type 2 diabetes mellitus.

[Vinculin and the androgen receptor in prostate cancer: expressions and correlations].

OBJECTIVE: To investigate the expressions of vinculin (VCL) and the androgen receptor (AR) in benign prostatic hyperplasia (BPH) and prostate cancer (PCa) and analyze their relationship with the clinical stage and pathological grade of PCa and the level of PSA. METHODS: We detected the expressions of VCL and AR in 18 cases of BPH and 38 cases of PCa by immunohistochemistry, analyzed the differences of VCL and AR expressions in BPH and PCa in different clinical stages and pathological grades of PCa, compared the primary levels of PSA, and studied their correlations. RESULTS: The positive rate of VCL was significantly higher in PCa than in BPH tissues (P < 0.05), while that of AR showed no significant differences between the two groups (P > 0.05). Both the expressions of VCL and AR were closely related with the clinical stage and pathological grade of PCa (P < 0.05), but not with the PSA level (P > 0.05). There was a positive correlation between the expressions of VCL and AR in PCa tissues (r = 0.489, P < 0.05). CONCLUSION: VCL is expressed differently in BPH and PCa, which may serve as an indicator for the differential diagnosis of benign and malignant prostate diseases. The expressions of AR and VCL are gradually reduced with the progression of PCa, with a positive correlation between them, and could be used jointly to evaluate the progression and prognosis of PCa.
