BACKGROUND: Hepatitis B virus (HBV) chronically infects approximately 350 million people worldwide, causing a major risk of liver disease and hepatocellular carcinoma (HCC). Many mouse models have been tried to establish HBV infection through injection with various HBV-containing plasmids. However, it is not well understood that different plasmids, all of which contain the similar HBV genome, even the same plasmids with different dose, results in opposite immune responses toward HBV. METHODS: In this study, we investigated the role of HBV-containing plasmid backbones and the HBcAg in determining the HBV persistence...

INTRODUCTION: Sleepiness and cardiovascular disease share common molecular pathways; thus, genetic risk factors for sleepiness may also predict cardiovascular disease risk. This study explored the associations between subjective sleepiness and single-nucleotide polymorphisms (SNPs) in candidate genes within oxidative stress, inflammatory, and neuronal pathways, which may contribute to sleepiness and downstream cardiovascular disease risk: Cytochrome B-245, Alpha Polypeptide (CYBA), Cytochrome B-245, Beta Polypeptide (CYBB), Neutrophil Cytosolic Factor (NCF2), Tumor Necrosis Factor-Alpha (TNFA), and Phosphodiesterase 4D (PDE4D)...

PURPOSE: It was shown in a previous cohort study that men with internal carotid artery (ICA) plaque, defined as focal wall thickness of ≥ 1.5 mm, had a threefold higher risk of stroke than those without plaque. We examined the relationship between arousal indices and sleep stages in patients with obstructive sleep apnea syndrome (OSAS) and carotid atherosclerosis. METHODS: Carotid atherosclerosis severity was evaluated using the maximal carotid wall intima-media thickness of the ICA (ICA-maxIMT) and plaque in 83 patients with OSAS...

BACKGROUND: It has been hypothesized that pre-capillary pulmonary hypertension (PH) may trigger sleep disordered breathing (SDB). In patients with chronic thromboembolic PH (CTEPH), pulmonary endarterectomy (PEA) is potentially effective to improve PH. We assessed the pre- and post-operative prevalence of SDB in CTEPH patients submitted to PEA and the relationship between SDB and clinical, pulmonary and hemodynamic factors. METHODS: Unattended cardiorespiratory recording was performed the night before and one month after elective PEA in 50 patients...

INTRODUCTION: Home sleep apnea testing (HSAT) is a diagnostic measure for obstructive sleep apnea hypopnea syndrome (OSAHS) in moderate/high risk patients. Some HSAT companies contain automatic analysis (AA). However, guidelines recommend manual analysis (MA) despite the weak evidence for this recommendation. OBJECTIVE: Evaluate the concordance between AA and MA of HSAT to make either a diagnosis and severity classification. METHODS: We evaluated AA and MA of HSAT between 2015 and 2016...

Objective: The aim of this study is to introduce a method in classifying the REM related OSA (RrOSA) and the potential clinical significance. Method: Two hundred and fifty patients (male: 219) with OSAS diagnosed by polysomnographywere recruited in the study. The RrOSAS was defined as the ratio of AHIs in REM and non REM sleep (R) greater than one. In RrOSAS group, patients were divided into RrOSAS Ⅰa (R>2, NREM_AHI<15), RrOSAS Ⅰb (R>2, NREM_AHI>15), and RrOSAS II (2>R>1) three subtypes...

BACKGROUND: There are currently no data on the prevalence of sleep-disordered breathing (SDB) in patients with newly-diagnosed lung cancer. This might be of interest given that SDB is associated with increased cancer incidence and mortality. Furthermore, intermittent hypoxia has been linked with tumor growth and progression. The aim of the current study was to investigate the prevalence of SDB in patients with newly-diagnosed lung cancer. METHODS: Patients with newly-diagnosed lung cancer from three centers in Germany were screened for SDB using a two-channel screening system (ApneaLink™)...

Study Objectives: While obstructive sleep apnea (OSA) is associated with overall cardiovascular disease and mortality, the association with atherosclerotic cardiovascular disease is less clear, especially in women. Recently, it has been suggested that OSA during REM sleep, associated with long apneas and deep desaturations, could have severe cardio-metabolic consequences. The aim of this study was to investigate whether OSA during REM sleep is associated with early signs of atherosclerosis in a population-based sample of women...

The treatment of obstructive sleep apnoea syndrome (OSAS) is still a matter of debate; among the different therapeutic alternatives, both surgical and conservative, treatment with continuous positive airway pressure (CPAP) is considered the "gold standard". The recent scientific literature reports that even if CPAP represents an effective solution for sleep apnoeas, 12% of patients do not benefit from its use. In most cases, primary collapse of the epiglottis is responsible for failure. We developed a surgical technique that provides a stable support to the epiglottis without influencing its function during swallowing while preserving laryngeal anatomy and physiology...

This study seeks to determine the objective and subjective success rates of anterior palatoplasty and its variants for the treatment of obstructive sleep apnoea (OSA). A systematic review with two independent searches of Medline, PubMed, Cochrane Library and Evidence Based Medicine Reviews was performed to identify publications relevant to OSA and anterior palatoplasty. All relevant studies published before 30 June 2015 were included. Six studies were included in the systematic review. The numbers of patients in each paper ranged from 13 to 77 (total = 240), and mean age ranged from 21 to 51 years...

Understanding features of the HIV-1 transmission process have the potential to inform biological interventions for prevention. We have examined the transmitted virus in a cohort of people who inject drugs and who are at risk of HIV-1 infection through blood contamination when injecting in a group. This study focused on seven newly infected participants in St. Petersburg, Russia, who were in acute or early infection. We used end-point dilution PCR to amplify single viral genomes to assess the complexity of the transmitted virus...

Epidemiological associations linking between obstructive sleep apnea and poorer solid malignant tumor outcomes have recently emerged. Putative pathways proposed to explain that these associations have included enhanced hypoxia inducible factor (HIF)-1α and vascular endothelial growth factor (VEGF) cell expression in the tumor and altered immune functions via intermittent hypoxia (IH). Here, we examined relationships between HIF-1α and VEGF expression and nocturnal IH in cutaneous melanoma (CM) tumor samples...
