Fluorescence-guided tumor visualization of colorectal cancer using tumor-initiating probe yellow in preclinical models.

Fluorescence-guided surgery has emerged as an innovative technique with promising applications in the treatment of various tumors, including colon cancer. Tumor-initiating probe yellow (TiY) has been discovered for identifying tumorigenic cells by unbiased phenotypic screening with thousands of diversity-oriented fluorescence library (DOFL) compounds in a patient-derived lung cancer cell model. This study demonstrated the clinical feasibility of TiY for tumor-specific fluorescence imaging in the tissues of patients with colorectal cancer (CRC).

Role of dietary potassium and salt substitution in the prevention and management of hypertension.

Cardiovascular diseases (CVD) continue to be the leading cause of deaths and disability worldwide and the major contributor is hypertension. Despite all the improvements in detecting hypertension together with technological advances and affordable, efficacious and relatively free of adverse effects anti-hypertensive agents, we continue to struggle to prevent the onset of hypertension and to control blood pressure (BP) to acceptable targets. The poor control of hypertension is commonly due to non-adherence to medications.

A comprehensive analysis of fruit, vegetable, and legume consumption and the risk of hypertension: results from the KoGES_CAVAS cohort.

Purpose: This study aimed to investigate the association between total consumption of fruits (F), vegetables (V), and legumes (L) and their subgroups and hypertension risk in adults aged ≥ 40 years in the Cardiovascular Disease Association Study (CAVAS).

Methods: We analyzed data from 10,325 normotensive participants using cumulative average dietary consumption from repeated food frequency questionnaires during the follow-up. Incidence rate ratios (IRRs) were estimated with a modified Poisson regression model and a robust error estimator to evaluate the association between hypertension risk and total consumption of fruits, vegetables, and legumes, as well as their 17 subgroups.

Heterogeneity of claudin 18.2 expression in metastatic gastric cancer.

Claudin 18.2 has emerged as a viable therapeutic target in gastric cancer (GC), but little is known about the heterogeneity of its expression in GC. This study investigated the heterogeneity of claudin 18.

Comparing blood pressure measurements between sitting in chairs and sitting on the floor.

Background: The current standard approach to measuring home blood pressure (BP) involves taking measurements while sitting in a chair. In cultures where floor sitting is common, including Korea, assessing BP while sitting on the floor would be more feasible. However, there is still a lack of research investigating whether BP measurements obtained while seated in a chair and while sitting on the floor can be regarded as interchangeable.

Proposed diagnostic and prognostic markers of primary malignant hepatic vascular neoplasms.

Introduction: Primary malignant hepatic vascular tumors with various malignant potentials include epithelioid hemangioendothelioma (EHE) and angiosarcoma (AS), which may overlap pathologically. This study aimed to compare the pathological findings of hepatic EHE with those of AS, in association with patient outcomes.

Methods: Fifty-nine histologically confirmed patients with 34 EHE and 25 AS were admitted to a tertiary hospital from 2003 to 2020.

Discordant PD-L1 results between 28-8 and 22C3 assays are associated with outcomes of gastric cancer patients treated with nivolumab plus chemotherapy.

Efficacy and safety of combination therapy with telmisartan, rosuvastatin, and ezetimibe in patients with dyslipidemia and hypertension: A randomized, double-blind, multicenter, therapeutic confirmatory, phase III clinical trial.

This study aimed to compare and evaluate the efficacy of the blood pressure (BP) control and cholesterol-lowering effects and safety of combination therapy with telmisartan, rosuvastatin, and ezetimibe versus rosuvastatin and ezetimibe double therapy or telmisartan single therapy in dyslipidemia patients with hypertension. After a wash-out/therapeutic lifestyle change period of ≥4 weeks, a total of 100 eligible patients were randomized and received one of three treatments for 8 weeks: (1) telmisartan 80 mg/rosuvastatin 20 mg/ezetimibe 10 mg (TRE), (2) rosuvastatin 20 mg/ezetimibe 10 mg (RE), or (3) telmisartan 80 mg (T). The primary endpoint was the efficacy evaluation of TRE by comparing changes in mean sitting systolic blood pressure (msSBP) and mean percentage change in low-density lipoprotein-C (LDL-C) from baseline after 8 weeks of treatment.

Blood pressure and variability responses to the down-titration of antihypertensive drugs.

Objectives: Several recent guidelines have proposed the gradual reduction of antihypertensive drugs for patients with well controlled blood pressure (BP). However, no studies have examined alterations in BP variability (BPV) during the down-titration of antihypertensives. This study aims to investigate changes in home BPV during the down-titration of antihypertensives.

Unusual or Uncommon Histology of Gastric Cancer.

This review comprehensively examines the diverse spectrum of gastric cancers, focusing on unusual or uncommon histology that presents significant diagnostic and therapeutic challenges. While the predominant form, tubular adenocarcinoma, is well-characterized, this review focuses on lesser-known variants, including papillary adenocarcinoma, micropapillary carcinoma, adenosquamous carcinoma, squamous cell carcinoma (SCC), hepatoid adenocarcinoma, gastric choriocarcinoma, gastric carcinoma with lymphoid stroma, carcinosarcoma, gastroblastoma, parietal cell carcinoma, oncocytic adenocarcinoma, Paneth cell carcinoma, gastric adenocarcinoma of the fundic gland type, undifferentiated carcinoma, and extremely well-differentiated adenocarcinoma. Although these diseases have different nomenclatures characterized by distinct histopathological features, these phenotypes often overlap, making it difficult to draw clear boundaries.
