Evaluating the Efficacy of Vonoprazan in Preventing Post-Endoscopic Variceal Band Ligation Ulcers: A Randomized Controlled Trial

The goal of this clinical trial is to learn if the medicine vonoprazan can help prevent ulcers that may develop after endoscopic variceal band ligation (EVBL) in adults with liver cirrhosis. These ulcers sometimes cause pain or delayed bleeding after the procedure. The study will also look at how well vonoprazan is tolerated and if it improves comfort after the procedure. The main questions this study will answer are: Does vonoprazan lower the number and severity of ulcers found on endoscopy after EVBL? Does vonoprazan reduce swallowing pain or chest discomfort compared with placebo? Is vonoprazan safe and well tolerated in people with liver cirrhosis? Researchers will compare vonoprazan 20 mg once daily with a placebo (a look-alike tablet that contains no active medicine) to see if vonoprazan works better to prevent these ulcers. Participants will: Take vonoprazan or placebo by mouth once daily for 14 days after EVBL. Return for a follow-up endoscopy about two weeks later to check for ulcers. Report any symptoms such as pain, nausea, or swallowing difficulty during the study. Adults aged 18 to 75 years with liver cirrhosis who undergo EVBL will be invited to join. Participants will be randomly assigned to one of two groups, and neither they nor the study doctors will know which treatment they receive (double-blind design). The study will take place at Mayo Hospital, Lahore, Pakistan, over about six months. By comparing vonoprazan to placebo, researchers hope to find a better way to protect the esophagus and stomach after EVBL, reduce post-procedure pain, and support faster recovery in people with liver cirrhosis.

Nursing Needs of Patients With Cirrhosis

The primary objective of this study is to examine the quality of life, disease-related knowledge, and perceived nursing needs of adult patients diagnosed with liver cirrhosis who attend the outpatient clinic at Landspítali University Hospital. The study aims to generate clinically relevant insights that may inform improvements in nursing care and patient support. The research questions are: 1. what is the quality of life of patients with cirrhosis. 2. How do patients with cirrhosis describe their knowledge about the disease; and 3. How do patients with cirrhosis describe their nursing needs. Three questionnaires will be given to the patients. To assess quality of life Chronic Liver Disease Questionnaire (CLDQ) will be used. To validate knowledge and nursing needs two questionnaires will be used. The disease severity will be evaluated through clinical indicators such as MELD and Child-Pugh scores. In addition, the study will analyze demographic variables, including age, gender, education level, and employment status, to identify potential associations with quality of life, disease burden, and perceived care needs. By integrating clinical data, patient-reported outcomes, and sociodemographic factors, the study aims to support the development of evidence-based, individualized nursing strategies that enhance symptom management, reduce hospital admissions, and improve overall well-being for individuals living with liver cirrhosis in Iceland. The study has scientific value at national and international level, as it is based on a recognized measurement tool (CLDQ) and is in line with international emphasis on individualized treatment and early intervention in liver diseases. The results will provide deeper understanding of the quality of life and nursing needs of individuals with cirrhosis and support the development of targeted nursing services. The study can also shed light on the relationship between demographic factors and disease severity with service needs, as well as support policy development, education and improvements in the care of patients with chronic liver diseases. This study will have practical benefits for both patients and the Icelandic healthcare system. By identifying the specific nursing needs of individuals with cirrhosis, the study will support the development of targeted, individualized care plans that address symptom burden, disease progression, and psychosocial challenges. Improved nursing services, such as nutritional counseling, symptom management, and education about self-care of the disease, can improve patients' quality of life and promote greater independence.

Laparoscopic Partial Splenectomy for Hypersplenism in Liver Cirrhosis Patients

In this study,the researchers compared the changes in immune function-related indicators in patients with liver cirrhosis following laparoscopic partial splenectomy,to determine whether this surgical intervention can enhance postoperative immune function and thereby improve patient outcomes.

Study on Proteomic and Microbiome Changes in Patients With Hepatic Encephalopathy (HE)

The objective of this observational study is to compare the differences in proteomics and gut microbiome between the liver cirrhosis group without hepatic encephalopathy and the hepatic encephalopathy group through proteomics and microbiome analysis, screen out the characteristic proteomics and microbiome of patients with hepatic encephalopathy, guide clinical diagnosis and treatment, and conduct in-depth research on the pathogenesis of hepatic encephalopathy. The main questions it aims to answer are: Are there any differences in serum proteomes between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy? If so, what are the main protein differences? There are differences in the fecal microbiome between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy? If so, what are the main microbial differences? This study will screen for the differences in proteomes and gut microbiomes between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy, and identify the characteristic proteomes and microbiomes of patients with hepatic encephalopathy to guide clinical diagnosis and treatment.

ProspEXPO : Study of the Associations Between Hepatocellular Carcinoma and Chemical and Psychosocial Environmental EXPOsome

The aim of the study is to build up a bio-collection of biological samples from patients with cirrhosis. Further work using this bio-collection will permit to describe the influence of different exposome factors (nutrition, physical activity, socio-demographic conditions, tobacco, alcohol, pollutants) on the occurrence of the main type of liver cancer (called HCC). Indeed, in the vast majority of cases, HCC develops within cirrhosis, and the factors that precipitate the progression of cirrhotic patients to HCC remain largely unknown.

Raman Spectroscopy-Based Deep Learning Model for Early Pan-Cancer Early Diagnosis

The goal of this observational study is to explore whether a Raman-based, deep learning-assisted approach can be used to develop an effective method for early pan-cancer screening. The study includes healthy individuals, patients at risk of cancer, and patients with diagnosed cancers. The main questions it aims to answer are: * Evaluating the deep-learning model's accuracy and specificity in identifying cancer-specific features in Raman spectral data and determining whether this method can accurately classify patients based on risk. * Identifying which model is more adaptable to the Raman spectrum * Providing an interpretable analysis of the model-generated diagnosis Participants are already being diagnosed and follow-up to determine the type of cancer.
