Real-world Outcomes of Durvalumab Consolidation in Elderly Patients With Unresectable NSCLC Following CCRT With Daily Low-dose Carboplatin.

Background/aim: The clinical benefits of durvalumab consolidation therapy following concurrent chemoradiotherapy (CCRT) with daily low-dose carboplatin in elderly patients with unresectable, locally advanced non-small cell lung cancer (NSCLC) remain unclear.

Patients And Methods: This was a single-institution retrospective cohort study. We analyzed the medical records of consecutive patients diagnosed with NSCLC who received CCRT with daily low-dose carboplatin from April 2014 to March 2021.

The relationship between muscle sympathetic nerve activity and serum fatty acid binding protein 4 at rest and during isometric handgrip exercise.

Fatty acid binding protein 4 (FABP4) is highly expressed in adipocytes. Lipolysis, caused by an elevated adrenergic input, has been suggested to contribute to elevated serum FABP4 levels in patients with cardiovascular diseases. However, the relationship between the serum FABP4 and efferent sympathetic nerve activity remains poorly understood.

Population-specific reference panel improves imputation quality for genome-wide association studies conducted on the Japanese population.

To improve imputation quality for genome-wide association studies (GWAS) conducted on the Japanese population, we developed and evaluated four Japanese population-specific reference panels. These panels were constructed through the augmentation of the 1000 Genomes Project (1KG) panel using Japanese whole genome sequencing (WGS) data, with sample sizes ranging from 1 K to 7 K individuals enrolled through the Biobank Japan (BBJ) project, and sequencing depths ranging from 3× to 30×. Among these panels, an augmented reference panel comprising 7472 WGS samples of mixed depth (1KG+7K) exhibit the greatest improvement in imputation quality relative to the Trans-Omics for Precision Medicine (TOPMed) reference panel.

Refractory phenotype of -sensitized asthma with bronchiectasis and allergic bronchopulmonary aspergillosis.

Background: Sensitization to mucus plugs, and bacterial colonization may coexist and relate to a refractory phenotype during follow-up in asthma with bronchiectasis and allergic bronchopulmonary aspergillosis (ABPA).

Objective: This study aimed to clarify the features of -sensitized refractory asthma with bronchiectasis and determine the refractory phenotype in this population and ABPA.

Methods: This study included cases of the oldest available -specific IgE data and chest computed tomography images from a nationwide survey of refractory asthma with bronchiectasis.

Variability in non-tumor areas of colorectal cancer patients as revealed by endoscopic intestinal step biopsies.

A comprehensive endoscopic small and large intestinal untargeted step biopsy procedure was conducted to compare gene expression between the normal intestinal mucosa of healthy individuals and that of patients with colorectal tumors. From 78 participants (healthy individuals [n = 17], patients with colorectal conventional adenomas [n = 6], patients with Tis-T1 colorectal cancer [n = 41], patients with T2-4 colorectal cancer [n = 14]), biopsies of normal mucosa of the terminal ileum, right-sided colon (cecum and ascending colon), and left-sided colorectum (descending colon, sigmoid colon, and rectum) were obtained using a lower gastrointestinal endoscope. RNA was extracted from all samples, and total transcriptome sequencing was performed.
