Update in uric acid, hypertension, and cardiovascular diseases.

A direct relationship between serum uric acid levels and hypertension, cardiovascular, renal and metabolic diseases has been reported in many basic and epidemiological studies. Among these, high blood pression is one of the most common features associated with hyperuricemia. In this regard, several small-scale interventional studies have demonstrated a significant reduction in blood pressure in hypertensive or prehypertensive patients on uric acid-lowering drugs.

Refusal of Subsequent Treatment in Patients With EGFR-mutant Non-small-cell Lung Cancer After Response to EGFR-TKIs.

Background/aim: During the course of effective and long-term treatment with epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), some elderly patients might decline further treatment after EGFR-TKI. We conducted a study to try and understand the reasons for this treatment decision.

Patients And Methods: We analyzed the medical records of all patients diagnosed with non-small-cell lung cancer with EGFR mutations between 2016 and 2021.

Successful endovascular repair of complicated pseudoaneurysm using Perclose ProGlide: A novel concept.

Iatrogenic pseudoaneurysm is common vascular complications of angiographic procedures. Patients with uncomplicated pseudoaneurysms can be managed with ultrasound-guided techniques. However, for complicated pseudoaneurysms, surgical repair of the artery is mandatory.

Impediments to Heart Transplantation in Adults With MELAS Cardiomyopathy.

Background: The heart is commonly involved in maternally inherited mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome caused by the MT-TL1 m.3243A>G mutation of the mitochondrial DNA. Heart transplantation (HTx) is controversial and has rarely been performed with conflicting results.

Discontinuation of Immune Checkpoint Inhibitor and Survival in Patients With Non-small-cell Lung Cancer Without a Driver Gene Mutation.

Background/aim: Patients with non-small-cell lung cancer treated with immune checkpoint inhibitors (ICI) might be forced to discontinue treatment for various reasons. We conducted a retrospective study to evaluate the impact of discontinuation of ICI treatment on patient prognosis.

Patients And Methods: We performed a retrospective study that reviewed the medical charts of 86 patients treated with ICI monotherapy and 34 patients treated with a combination of ICI and chemotherapy during the period from February 2016 to February 2022 at our two hospitals.

Comparison of the incidence of depression before and after endovascular treatment in patients with lower limb peripheral artery disease.

Depression is a chronic illness that affects mood, physical health, and overall vitality and quality of life. Depression has been associated with an increased risk of all-cause and cardiovascular mortality among patients with peripheral arterial disease (PAD). Therefore, this study aimed to compare the incidence of depression before and after endovascular treatment in patients with lower limb PAD.

Prognostic impact of atrial fibrillation on the outcomes of peripheral artery disease according to preoperative symptoms for endovascular revascularization.

Peripheral artery disease (PAD) and atrial fibrillation (AF) are associated with major cardiovascular and cerebrovascular events (MACCE). However, outcomes stratified according to the preoperative symptoms of PAD in patients with AF have not been sufficiently investigated. This was a retrospective study of prospectively collected data pertaining to 2237 patients (1179 patients with intermittent claudication [IC] and 1058 patients with critical limb-threatening ischemia [CLTI]) who underwent endovascular therapy at 34 hospitals between August 2014 and August 2016.

Background/aim: To clarify the clinical significance of the absolute increase in the number and proportion of peripheral eosinophils associated with immune checkpoint inhibitor (ICPI) treatment in non-small cell lung cancer (NSCLC) patients.

Patients And Methods: We performed a retrospective study, by reviewing the medical charts of 191 patients who were treated with ICPI monotherapy and 80 patients treated with the combination of ICPI and chemotherapy during the period from February 2016 and April 2021.

Results: In patients treated with ICPI monotherapy, there was a significant difference in time to treatment failure (TTF) between the two groups divided by eosinophils ≥ or <10%.

Common exacerbation-prone phenotypes across asthma and chronic obstructive pulmonary disease (COPD).

Background And Objectives: Chronic inflammatory airway diseases, including asthma and chronic obstructive pulmonary disease (COPD), are complex syndromes with diverse clinical symptoms due to multiple pathophysiological conditions. In this study, using common and shared risk factors for the exacerbation of asthma and COPD, we sought to clarify the exacerbation-prone phenotypes beyond disease labels, and to specifically investigate the role of the IL4RA gene polymorphism, which is related to type 2 inflammation, in these exacerbation-prone phenotypes.

Methods: The study population comprised patients with asthma (n = 117), asthma-COPD overlap (ACO; n = 37) or COPD (n = 48) and a history of exacerbation within the previous year.

The "bud" of an aortic aneurysm.

An overlooked "bud" of an aortic aneurysm on a chest radiography resulted in a saccular aortic aneurysm 9 years later. This eye-catching image showed us the importance of not only documenting abnormalities in regular radiography but also further imaging evaluation for definitive diagnosis and continuous image follow-up.

Impact of body mass index on the outcome of Japanese patients with cardiovascular diseases and/or risk factors hospitalized with COVID-19 infection.

Background: Obesity is reported to be a predictor of adverse clinical events in coronavirus disease 2019 (COVID-19) in Western countries. However, there are limited data reported regarding the prognostic impact of obesity in Asian patients. We investigated the relationship between body mass index (BMI) and in-hospital outcomes in 580 Japanese patients with cardiovascular disease and/or risk factors and who were admitted for COVID-19 infection using data from 49 hospitals in Japan.

Association between time to treatment failure and peripheral eosinophils in patients with non-small cell lung cancer treated with immune checkpoint inhibitors.

Introduction: There is an unmet clinical need to identify biomarkers predicting which patients with non–small cell lung cancer (NSCLC) would benefit from treatment with immune checkpoint inhibitors (ICPIs). Objectives: The purpose of this study was to draw a detailed time to treatment failure (TTF) curve with information on the changes in peripheral eosinophil expression during ICPI treatment for NSCLC, and to clarify whether eosinophil expression can predict prolonged TTF. Patients and methods: In 259 patients with NSCLC treated with ICPI therapy, peripheral eosinophil counts and percentages at the time of each ICPI administration were evaluated from the beginning of ICPI treatment up to TTF.

Impact of Anticoagulation Therapy on the Risk of Pulmonary Embolism and Bleeding Events in Patients with Isolated Distal Deep-Vein Thrombosis.

The efficacy of anticoagulation for isolated distal DVT (id-DVT) is still uncertain and controversial. The aim of this study was to elucidate the risk of pulmonary embolism (PE) from id-DVT and to investigate the need for anticoagulants.We identified hospitalized patients with id-DVT diagnosed by lower-extremity ultrasonography (LEUS) from January 2013 to December 2013 in our institute.
