Blood digital polymerase chain reaction as a potential method to detect human epidermal growth factor receptor 2 amplification in non-small cell lung cancer.

Background: This study aimed to verify the feasibility of human epidermal growth factor receptor-2 () amplification detection by digital polymerase chain reaction (dPCR) in non-small cell lung cancer (NSCLC) patients and explore whether amplification could be detected in circulating tumor DNA (ctDNA) by dPCR.

Methods: A total of 112 fresh biopsy tissues and 88 blood samples from NSCLC patients were collected. The serum ctDNA was obtained from blood samples.

International Consensus Document on Obstructive Sleep Apnea.

The main aim of this international consensus document on obstructive sleep apnea is to provide guidelines based on a critical analysis of the latest literature to help health professionals make the best decisions in the care of adult patients with this disease. The expert working group was formed primarily of 17 scientific societies and 56 specialists from a wide geographical area (including the participation of 4 international societies), an expert in methodology, and a documentalist from the Iberoamerican Cochrane Center. The document consists of a main section containing the most significant innovations and a series of online manuscripts that report the systematic literature searches performed for each section of the international consensus document.

Prognostic value of symptoms at lung cancer diagnosis: a three-year observational study.

Background: Lung cancer is mainly diagnosed at advanced or locally advanced stages, usually when symptoms become evident. However, sometimes it may be diagnosed incidentally during routine care, while patients are still asymptomatic. Prognosis differences based on symptomatic presentation have been partially explored.

MicroRNA Profile of Cardiovascular Risk in Patients with Obstructive Sleep Apnea.

Background: Obstructive sleep apnea (OSA) is a common disease caused by repeated episodes of collapse of the upper airway during sleep and is associated with the development of cardiovascular disease (CVD). However, there is high heterogeneity in the impact of OSA on patients. Until now, the profile of OSA patients at risk of developing CVD has not been defined, including the measurable variables that could be used to predict the CVD risk of a patient with OSA.

Circulating microRNA profile as a potential biomarker for obstructive sleep apnea diagnosis.

Evaluation of microRNAs (miRNAs) could allow characterization of the obstructive sleep apnea (OSA) and help diagnose it more accurately. We aimed to examine circulating miRNA profiles to establish the differences between non-OSA and OSA patients. Additionally, we aimed to analyse the effect of continuous positive airway pressure (CPAP) treatment on the miRNA profile.

Upcoming Scenarios for the Comprehensive Management of Obstructive Sleep Apnea: An Overview of the Spanish Sleep Network.

Sleep is considered an essential part of life and plays a vital role in good health and well-being. Equally important as a balanced diet and adequate exercise, quality and quantity of sleep are essential for maintaining good health and quality of life. Sleep-disordered breathing is one of the most prevalent conditions that compromises the quality and duration of sleep, with obstructive sleep apnea (OSA) being the most prevalent disorder among these conditions.

Comparative and functional analysis of plasma membrane-derived extracellular vesicles from obese vs. nonobese women.

Background: Membrane-derived extracellular vesicles (EVs) are released to the circulation by cells found in adipose tissue, transferring microRNAs (miRNAs) that may mediate the adaptive response of recipient cells. This study investigated plasma EVs from obese vs. nonobese women and their functional impact in adipocytes.

Biomarkers of carcinogenesis and tumour growth in patients with cutaneous melanoma and obstructive sleep apnoea.

The goal of this study was to assess the relationship between the severity of obstructive sleep apnoea (OSA) and the levels of carcinogenesis- and tumour growth-related biomarkers in patients with cutaneous melanoma.This multicentre observational study included patients who were newly diagnosed with melanoma. The patients were classified as non-OSA (apnoea-hypopnoea index (AHI) 0-5 events·h), mild OSA (AHI 5-15 events·h) and moderate-severe OSA (AHI >15 events·h).
