Diagnosis of obstructive sleep apnea using a bio-radar contact-free system compared with an established HST device in older adults.

Goal And Aims: To compare a bio-radar contact-free monitoring device in diagnosing obstructive sleep apnea (OSA) in older people with an established home sleep apnea testing system (HST).

Focus Method/technology: A bio-radar contact-free monitoring device (OrbSense+).

Reference Method/technology: An established HST, Alice NightOne.

Methylation Levels are Associated with Lung Cancer Development in Male Patients with Chronic Obstructive Pulmonary Disease.

Purpose: The mechanism of lung cancer (LC) in male patients with chronic obstructive pulmonary disease (COPD) has not been well understood, and the early diagnosis is currently challenging. The study aimed to explore the association of DNA methylation levels with LC development in male COPD patients.

Patients And Methods: A total of 147 male participants were divided into four groups, ie, COPD+LC group, COPD group, LC group, and control (CON) group.

The Role of Aldosterone in OSA and OSA-Related Hypertension.

Obstructive sleep apnea (OSA) is regarded as an independent risk factor for hypertension. The possible mechanism includes oxidative stress, endothelial injury, sympathetic excitement, renin-angiotensin-aldosterone system activation, etc. Clinical studies have found that there is a high coexistence of OSA and primary aldosteronism in patients with hypertension and that elevated aldosterone levels are independently associated with OSA severity in resistant hypertension.

Moderate to severe OSA screening based on support vector machine of the Chinese population faciocervical measurements dataset: a cross-sectional study.

Objectives: Obstructive sleep apnoea (OSA) has received much attention as a risk factor for perioperative complications and 68.5% of OSA patients remain undiagnosed before surgery. Faciocervical characteristics may screen OSA for Asians due to smaller upper airways compared with Caucasians.

Burden of Sleep Disturbance During COVID-19 Pandemic: A Systematic Review.

Coronavirus disease 2019 (COVID-19) pandemic may exert adverse impacts on sleep among populations, which may raise awareness of the burden of sleep disturbance, and the demand of intervention strategies for different populations. We aimed to summarize the current evidence for the impacts of COVID-19 on sleep in patients with COVID-19, healthcare workers (HWs), and the general population. We searched PubMed and Embase for studies on the prevalence of sleep disturbance.

Therapeutic Agents Rounding Up the Immunopathology of COVID-19.

COVID-19 pandemic has caused more than 3 million deaths globally during the past year. The direct attack from SARS-CoV-2 and hyperactivated immune response contribute to the progress and deterioration of COVID-19. After the virus invades, the activation and release of cytokines/chemokines cause "cytokine storm", leading to acute respiratory distress syndrome (ARDS) and multiple organs dysfunction syndrome (MODS).

Autophagy Promotes Peripheral Nerve Regeneration and Motor Recovery Following Sciatic Nerve Crush Injury in Rats.

Autophagy maintains cellular homeostasis by stimulating the lysosomal degradation of cytoplasmic structures, including damaged organelles and dysfunctional proteins. The role of autophagy in the renewal and regeneration of injured peripheral nerves remains poorly understood. The current study investigated the role of autophagy in peripheral nerve regeneration and motor function recovery following sciatic nerve crush injury in rats by stimulating or suppressing autophagy and detecting the presence of autophagosomes and LC3-II expression by electron microscopy and Western blotting, respectively.

[Determination of the 50% effective concentration of dexmedetomidine as an adjuvant in combined spinal-epidural anesthesia with Narcotrend].

Objective: To determine the 50% effective concentration (EC(50) ) of dexmedetomidine (DEX) as an adjuvant for achieving the minimal effect in combined spinal-epidural anesthesia (CSEA) with Narcotrend.

Methods: Thirty ASA class I-II patients undergoing CSEA were allocated to receive 0.5% bupivacaine injection (2 ml) in the subarachnoid space, followed by a target-controlled infusion of DEX for at least 60 min.

[Effect of the degree of muscle relaxation on motor-evoked potential elicited by transcranial electrical stimulation in spine surgery].

Objective: To study the effect of the degree of muscle relaxation on motor-evoked potential elicited by transcranial electrical stimulation in patients undergoing spine surgery.

Methods: Sixty ASA I or II patients undergoing spine surgery were randomly divided into 5 groups (n=12). After an initial intubation, continuous cisatracurium infusion was administered with continuous monitoring of T1.

[Influence of epidural ropivacaine in combination with fentanyl for labor analgesia on the clinical outcome of labor].

Objective: To investigate the effect of epidural ropivacaine in combination with fentanyl for labor analgesia on the clinical outcome of labor.

Methods: A retrospective study was conducted involving 281 healthy primiparas, including 106 undergoing spontaneous labor who received epidural 0.15% ropivacaine in combination with fentany (1microg/ml) and 175 without epidural analgesia.
