With an aging population seeking infertility treatment, diminished ovarian reserve (DOR) is a prevalent indication for assisted reproductive technology (ART). This study aims to investigate the relationship between sleep parameters and DOR among women attending an infertility clinic. Methods We consecutively enrolled women attending an infertility clinic from July 2020 to June 2021.

Article Synopsis
  • Scientists studied the relationship between a specific molecule called miR-210-3p and cancer growth in patients with a sleep condition called obstructive sleep apnea (OSA).
  • They found that higher levels of miR-210-3p in lung cancer patients with OSA were linked to worse sleep, like having low oxygen levels during sleep.
  • The research showed that when there is less oxygen (intermittent hypoxia), miR-210-3p helps tumors grow more by lowering a protein called E2F3, suggesting that targeting miR-210-3p may help treat these tumors.

Background: Exosomes are involved in cell-to-cell communication in numerous diseases including cardiovascular diseases, neurological diseases. Little attention has been dedicated to exosomal circular RNAs in obstructive sleep apnea (OSA)-related cardiovascular diseases. The aim of this study was to explore the role of exosomal circular RNA ZNF292 (circZNF292) on AC16 cells exposure to intermittent hypoxia (IH).

Purpose: Circular RNAs (circRNAs) are recently identified as a class of non-coding RNAs that participate in the incidence of acute myocardial infarction (AMI). However, circRNAs expression pattern in obstructive sleep apnea (OSA) with AMI remains unknown. The aim was to investigate circRNAs expression alteration in serum exosomes derived from OSA patients with AMI.

Purpose: Ferroptosis is reported to be involved in the chronic intermittent hypoxia (CIH)-related liver damage in vivo. Nuclear factor E2-related factor 2 (Nrf2) has an essential role in the regulation of ferroptosis. This study tested the hypothesis that intermittent hypoxia (IH) could lead to hepatocyte ferroptosis in vitro and the function of Nrf2 in IH-induced hepatocyte ferroptosis.

Purpose: The association between obstructive sleep apnea (OSA) and cancer risks gaining more and more attention. Data on the association between OSA and lung cancer risk are limited. This study is to investigate whether a link exists between low-dose computed tomography (LDCT) scanning of the chest findings, carcinoembryonic antigen (CEA) and OSA in patients suspected of OSA.

Intermittent hypoxia (IH) is a prominent feature of obstructive sleep apnea (OSA) which is increasingly recognized as a key risk factor for liver injury. Circular RNAs (circRNAs) has been suggested to act as a regulator of multiple biological processes. However, there is no study evaluating circRNAs alterations and potential role of circRNAs in OSA-related liver injury.

Article Synopsis
  • The study investigates the connection between obstructive sleep apnea (OSA) and increased risk of heart disease by examining how ferroptosis, a type of cell death linked to iron overload, impacts heart injury caused by intermittent hypoxia (IH).
  • In experiments with human heart cells and mice, researchers found that IH reduced critical protective proteins (GPX4 and xCT) and caused heart damage associated with higher ferroptosis levels and endoplasmic reticulum stress (ERS).
  • Treatment with ferroptosis inhibitors and N-acetylcysteine showed promise in reducing heart injury and ERS in mice exposed to IH, suggesting that targeting ferroptosis may help in managing myocardial damage related to OSA.

Article Synopsis
  • Patients with obstructive sleep apnoea (OSA) face significant damage to their blood vessels, primarily due to a condition called chronic intermittent hypoxia (CIH).
  • The study examined how CIH impacts human vein endothelial cells by monitoring cell health, mitochondrial function, and specific protein expressions.
  • Findings revealed that CIH led to decreased cell viability and increased cell death, but treatments with certain drugs improved cell survival and mitochondrial health, indicating that a protein called PPARγ plays a critical role in these protective processes.

Article Synopsis
  • Obstructive sleep apnea (OSA) is linked to atherosclerosis and the study focuses on the role of long non-coding RNA MALAT1 in vascular endothelial damage caused by intermittent hypoxia (IH).
  • IH treatment decreased cell viability and increased apoptosis in human umbilical vein endothelial cells (HUVECs), with MALAT1 levels rising significantly in response to IH.
  • Knockdown of MALAT1 worsened endothelial injury and its effects were mediated through the interaction with miR-142-3p and HMGB1, suggesting a critical role for MALAT1 in regulating endothelial health under IH conditions.

Purpose: Prior reports have examined the relationship between obstructive sleep apnea (OSA) and the mortality rate of lung cancer. However, the findings remain controversial. The present meta-analysis was performed to assess the relationship between OSA and increased risk of mortality in patients with lung cancer.

Purpose: Continuous positive airway pressure (CPAP) is the current gold-standard treatment for moderate to severe obstructive sleep apnea (OSA), and upper airway anatomy plays an increasingly important role in evaluating the efficacy of CPAP therapy. The aim of this observational study was to investigate the influence of upper airway anatomy on CPAP titration in OSA patients assessed by computed tomography (CT) during Müller's maneuver.

Methods: Consecutive patients under investigation for OSA by undergoing polysomnography and CT scan of the upper airway while awake were enrolled.

Purpose: Obstructive sleep apnea (OSA) has been related to an increased risk of liver injury. Ferroptosis is a form of programmed cell death implicated in multiple physiological and pathological processes. This study aimed to explore the role of ferroptosis in chronic intermittent hypoxia (CIH)-induced liver injury as well as to uncover the underlying mechanisms using a CIH rat model.

Background: Obstructive sleep apnea (OSA) has been demonstrated to be associated with an increase of oxidative stress. However, whether circulating malondialdehyde (MDA), a widely used biomarker of oxidative stress, could be reduced by the treatment of OSA by continuous positive airway pressure (CPAP) is debated. The present meta-analysis was performed to determine the effect of CPAP treatment on circulating MDA among patients with OSA.

Background: Obstructive sleep apnea hypopnea syndrome (OSAHS) is a contributing factor for non-alcoholic fatty liver disease (NAFLD). Non-invasive algorithms including fatty liver index (FLI) and hepatic steatosis index (HSI) have been used as a screening test for NAFLD in epidemiologic studies. The aim of this study is to compare the diagnostic accuracy of FLI and HSI for NAFLD detection in adults with OSAHS.
