Objective: Vonoprazan is a potassium-competitive acid blocker, a new type of acid-suppressing drug, and has recently become available for peptic ulcers, gastroesophageal reflux disease, and Helicobacter pylori (H. pylori) eradication. Its efficacy for H. pylori eradication has been reported. However, the evidence for its efficacy and feasibility remains limited. We aimed to compare the feasibility, effectiveness and safety of vonoprazan-based triple therapy with conventional proton pump inhibitor (PPI)-based triple therapy in multicenter clinical practice.
Methods: We performed a multicenter retrospective study on patients receiving first-line H. pylori eradication therapy between March 2013 and November 2015 with either vonoprazan-based triple therapy or conventional PPI-based triple therapy.
Results: A total of 2715 patients aged 63.0 ± 12.1 years (1412 [52.0%] males) were analyzed. Eradication rates were 87.2% (368/422) for vonoprazan-based therapy and 72.4% (1661/2293) for conventional PPI-based therapy (P < 0.01). Among the former group, there were 10 cases of diarrhea, six of nausea/vomiting, and five of rash, but the rates of these adverse events were similar to those in the conventional PPI group.
Conclusion: Vonoprazan-based triple therapy is feasible, and has a higher rate for H. pylori eradication than conventional PPI as a first-line regimen.

The emergence of self-propelling magnetic nanobots represents a significant advancement in the field of drug delivery. These magneto-nanobots offer precise control over drug targeting and possess the capability to navigate deep into tumor tissues, thereby addressing multiple challenges associated with conventional cancer therapies. Here, Fe-GSH-Protein-Dox, a novel self-propelling magnetic nanobot conjugated with a biocompatible protein surface and loaded with doxorubicin for the treatment of triple-negative breast cancer (TNBC), is reported.

Alzheimer's disease (AD) is a neurodegenerative disease that is significantly characterized by cognitive and memory impairments, which worsen significantly with age. In the late stages of AD, metal ion disorders and an imbalance of reactive oxygen species (ROS) levels occur in the brain microenvironment, which causes abnormal aggregation of β-amyloid (Aβ), leading to a significant worsening of the AD symptoms. Therefore, we designed a composite nanomaterial of macrophage membranes-encapsulated Prussian blue nanoparticles (PB NPs/MM).

Background: Black women have a 40% higher breast cancer (BC) mortality rate than White women and are at a higher risk of acquiring cardiovascular disease. Proton therapy (PT) can be used to mitigate cardiac radiation exposure; however, PT remains a scarce resource in the United States. We report on the cardiovascular profiles of patients undergoing PT to determine the potential benefit of PT for Black women when compared to non-Black patients.

Introduction: Chronic obstructive pulmonary disease (COPD) is associated with exacerbations which can reduce quality of life and increase mortality. Single-inhaler triple therapy (SITT) is recommended for maintenance treatment of COPD among patients experiencing exacerbations despite dual-therapy use. This real-world comparative effectiveness study compared the impact of SITTs, fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), and budesonide/glycopyrrolate/formoterol fumarate (BUD/GLY/FORM), on COPD exacerbations and mortality.
