Since its proposal, the Model for End-Stage Liver Disease (MELD) score has been employed to predict short-term mortality among patients with chronic liver disease and those awaiting liver transplantation, serving as the primary criterion for organ allocation. However, as the demographic and epidemiological characteristics of chronic liver disease and liver transplantation have evolved, a range of MELD-related scores has emerged, including MELD-Na, iMELD, delta MELD, MELD XI, MELD-LA, and pediatric end-stage liver disease, culminating in the recently proposed MELD 3.0, which builds upon MELD-Na. This study aimed to comprehensively review and summarize relevant studies on MELD 3.0 in various scenarios, assessing its effectiveness in organ allocation, post-transplantation outcomes, and mortality prediction for patients with end-stage liver disease. Our preliminary findings indicate superior predictive performance of MELD 3.0, warranting further in-depth investigations to broaden its clinical implications.

Mesothelioma is an aggressive tumor with a poor prognosis. Histological diagnosis of mesothelioma using limited tissue samples can be challenging. Carbonic anhydrase IX (CAIX) is a transmembrane protein that is overexpressed in a variety of solid tumors. This study aimed to investigate the clinical utility of CAIX expression in the differential diagnosis of pleural mesothelioma from non-small cell lung carcinoma (NSCLC).

Unstained tissue microarray slides composed of 56 cases of pleural mesothelioma and 82 cases of NSCLC were subjected to immunohistochemical staining using a mouse anti-human antibody against CAIX.

Of the 38 epithelioid mesothelioma cases, 34 (89%) displayed diffuse and strong cytoplasmic membrane reactivity, while the remaining four cases (11%) showed weak to moderate staining in tumor cells. Five out of sixteen (5/16) sarcomatoid mesothelioma cases were negative. Among the non-small cell lung carcinoma cases, 76% (32/42) of adenocarcinomas and 57% (21/37) of squamous cell carcinomas were completely negative, whereas the remaining cases showed focal weak expression of CAIX.

Our study demonstrates that CAIX expression has a high sensitivity (100%) in detecting pleural epithelioid mesothelioma, which is comparable to or better than currently used mesothelial markers. The specificity of CAIX is within a comparable range to that of commonly used mesothelial markers for differentiating epithelioid mesothelioma from NSCLC. Therefore, we recommend that CAIX immunohistochemistry staining be considered as an additional tool for the differential diagnosis of mesothelioma, particularly pleural epithelioid mesothelioma, from its common mimicker, NSCLC.

The treatment of Helicobacter pylori (H. pylori) infection remains a challenge due to the increasing prevalence of drug-resistant bacteria. It is hypothesized that using more potent acid suppressants, such as potassium-competitive acid blockers (P-CABs) like Vonoprazan, may improve eradication rates. The aim of this study was to compare the effectiveness of H. pylori eradication regimens containing Vonoprazan with those containing proton pump inhibitors for H. pylori infection.

Two hundred and thirty-two patients were assigned to two groups. Group I (treatment-naïve) included: Arm 1 (intervention arm) with 58 patients who received Clarithromycin 500 mg twice daily, Amoxicillin 1 mg twice daily, and Vonoprazan 20 mg twice daily; and Arm 2 (comparator arm) with 58 patients who received Clarithromycin 500 mg twice daily, Amoxicillin 1 mg twice daily, and Esomeprazole 20 mg twice daily. Group II (treatment-experienced) included: Arm 3 (intervention arm) with 58 patients who received Levofloxacin 500 mg once daily, Vonoprazan 20 mg twice daily, Nitazoxanide 500 mg twice daily, and Doxycycline 100 mg once daily; and Arm 4 (comparator) with 58 patients who received Levofloxacin 500 mg once daily, Esomeprazole 20 mg twice daily, Nitazoxanide 500 mg twice daily, and Doxycycline 100 mg once daily. All patients received their treatment regimens for 14 days. H. pylori eradication was assessed four weeks after treatment.

The successful eradication rate was higher in Arm 1 (58.6%) compared to Arm 2 (50%), and higher in Arm 3 (50%) compared to Arm 4 (43.1%). H. pylori eradication regimens including P-CABs were well-tolerated with a low incidence of adverse events.

The results of P-CAB-based eradication regimens are comparable to those of proton pump inhibitor-based regimens.

A colouterine fistula is an extremely rare condition that has been reported in various diseases, including diverticulitis, sigmoid colon malignancy, and complications from radiotherapy. It can also arise from iatrogenic conditions such as the insertion of intrauterine devices, endometrial curettage with urinary tract and bowel perforation, and obstetrical injury. Although colovaginal fistula caused by a foreign body has been reported, colouterine perforation by a foreign body has not been previously documented. We report the first case of foreign body colouterine perforation and its successful treatment by endoscopic removal and repair, resulting in the complete resolution of symptoms without the need for surgery. This case is highly significant due to its rare occurrence and successful treatment by endoscopic removal and repair without the usual and expected necessity for surgical intervention.

Coronary artery disease (CAD) is increasingly observed in patients with liver cirrhosis. However, data on the incidence and prevalence of CAD in cirrhotic patients are heterogeneous, and the association remains uncertain. In this study, we aimed to conduct a systematic review and meta-analysis to address these issues.

PubMed, EMBASE, and Cochrane Library databases were searched. Incidence, prevalence, and factors associated with CAD were pooled using a random-effects model. Risk ratio (RR) and odds ratio (OR), with their 95% confidence interval (CI), were calculated to evaluate differences in CAD incidence and prevalence between patients with and without liver cirrhosis.

Fifty-one studies were included. The pooled incidences of CAD, acute coronary syndromes, and myocardial infarction (MI) were 2.28%, 2.02%, and 1.80%, respectively. Liver cirrhosis was not significantly associated with CAD incidence (RR = 0.77; 95% CI = 0.46–1.28) or MI (RR = 0.87; 95% CI = 0.49–1.57). The pooled prevalence of CAD, acute coronary syndromes, and MI was 18.87%, 12.54%, and 6.12%, respectively. Liver cirrhosis was not significantly associated with CAD prevalence (OR = 1.29; 95% CI = 0.83–2.01) or MI (OR = 0.58; 95% CI = 0.28–1.22). Non-alcoholic steatohepatitis, hepatitis C virus, advanced age, male sex, diabetes mellitus, hypertension, hyperlipidemia, smoking history, and family history of CAD were significantly associated with CAD in cirrhotic patients.

CAD is common in cirrhotic patients, but cirrhosis itself may not be associated with an increased CAD risk. In addition to traditional risk factors, non-alcoholic steatohepatitis and hepatitis C virus infection are also associated with CAD presence in cirrhotic patients.

T-cell receptor (TCR) sequencing provides a novel platform for insight into and characterization of intricate T-cell profiles, advancing the understanding of tumor immune heterogeneity. Recently, transarterial chemoembolization (TACE) combined with systemic therapy has become the recommended regimen for advanced hepatocellular carcinoma. The regulation of the immune microenvironment after TACE and its impact on tumor progression and recurrence has been a focus of research. By examining and tracking fluctuations in the TCR repertoire following combination treatment, novel perspectives on the modulation of the tumor microenvironment post-TACE and the underlying mechanisms governing tumor progression and recurrence can be gained. Clarifying the distinctive metrics and dynamic alterations of the TCR repertoire within the context of combination therapy is imperative for understanding the mechanisms of anti-tumor immunity, assessing efficacy, exploiting novel treatments, and further advancing precision oncology in the treatment of hepatocellular carcinoma. In this review, we initially summarized the fundamental characteristics of TCR repertoire and depicted immune microenvironment remodeling after TACE. Ultimately, we illustrated the prospective applications of TCR repertoires in TACE combined with systemic therapy.

Percutaneous endoscopic gastrostomy (PEG) tube placement is a common procedure used to provide medium- and long-term enteral nutrition to patients. Although generally considered safe, PEG tube placement can be associated with various potential complications. We report a case of gastrocolocutaneous fistula formation in a patient who presented with severe abdominal pain, new-onset diarrhea, and feculent emesis nine days after PEG tube placement. Awareness of this rare complication can facilitate the recognition of colonic perforation during gastrostomy tube placement and enable early detection of the complication post-procedurally. Additionally, we discuss various techniques that may be employed to prevent this complication during PEG tube placement.
