Impact of the COVID-19 pandemic on cardiac implantable electronic device implantation in China: Insights from 2 years of changing pandemic conditions.

Background: A substantial reduction in the number of cardiac implantable electronic device (CIED) implantation was reported in the early stages of the COVID-19 pandemic. None of the studies have yet explored changes in CIED implantation during the following pandemic.

Objective: To explore changes in CIED implantation during the COVID-19 pandemic from 2020 to 2021.

Continuous positive airway pressure versus mandibular advancement device in the treatment of obstructive sleep apnea: a systematic review and meta-analysis.

Background: The goal of this study was to review relevant randomized controlled trials in order to determine the efficacy of continuous positive airway pressure (CPAP) versus mandibular advancement device (MAD) in the treatment of obstructive sleep apnea (OSA).

Methods: Using appropriate keywords, we identified relevant studies using PubMed, the Cochrane Library, and Embase. Key pertinent sources in the literature were also reviewed, and all articles published through October 2019 were considered for inclusion.

Fluorescence Sensing with Cellulose-Based Materials.

Cellulose-based materials functionalized with fluorescence sensors are highly topical and are employed in many areas of functional materials, including the sensing of heavy-metal ions and anions as well as being widely used as chemical sensors and tools for environmental applications. In this Review, we cover recent progress in the development of cellulose-based fluorescence sensors as parts of membranes and nanoscale materials for the detection of biological analytes. We believe that this Review will be of interest to chemists, chemical engineers, and biochemists in the sensor community as well as researchers working with biological material systems.

Fluorescence detection and removal of copper from water using a biobased and biodegradable 2D soft material.

We have developed a green and robust fluorogenic (λ = 410 nm, λ = 510 nm) cellulose membrane using graphene oxide (GO) as a construct for simultaneous copper ion recognition and filtration at environmentally relevant levels. The detection limit and removal limit of Cu are 7.3 × 10 M and 1000 ppm, respectively.

The prognostic significance of fragmented QRS in patients with left ventricular noncompaction cardiomyopathy.

Background: Fragmented QRS complexes (fQRS) were proven to be associated with the prognosis of several heart diseases. However, no data is available regarding fQRS in left ventricular noncompaction cardiomyopathy (LVNC), in which the outcome varies greatly and a simple yet practicable prognostic predictor is needed. The purpose of this study was to determine the prognostic value of fQRS in LVNC patients.

An ionic liquid supported CeO nanoparticles-carbon nanotubes composite-enhanced electrochemical DNA-based sensor for the detection of Pb.

An electrochemical sensor incorporating a signal enhancement for the determination of lead (II) ions (Pb) was designed on the basis of the thrombin-binding aptamer (TBA) as a molecular recognition element and ionic liquid supported cerium oxide (CeO) nanoparticles-carbon nanotubes composite modification. The composite comprises nanoparticles CeO, multi-wall carbon nanotubes (MWNTs) and hydrophobic room temperature ionic liquid (RTIL) 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIMBF). The electrochemical sensors were fabricated by immersing the CeO-MWNTs-EMIMBF modified glassy carbon electrode (GCE) into the solution of TBA probe.

Ablation efficacy and electrical morphology of a novel 18-hole open-irrigated catheter.

Introduction: The 6-hole open-irrigated catheter (SHOI) is increasingly used in radiofrequency (RF) ablation of arrhythmias. However, deep transmural lesions are not always achieved, and volume overload caused by irrigated ablation is another problem that should be concerned. The purpose of this study was to analyze and compare the ablation effect and electrical morphology between a novel 18-hole open-irrigated catheter (EHOI) and SHOI.

[Association between adipocyte fatty acid binding proteins/adiponectin and coronary artery stenosis].

Objective: To observe the relationship between serum and monocyte-derived-macrophages secreted adipocyte fatty acid binding protein (A-FABP), adiponectin (or A-FABP/adiponectin ratio) and coronary artery disease.

Methods: Three hundred and forty subjects underwent coronary angiography (CAG) were classified into CAD group (n = 211) and non-CAD group (n = 129) according to the CAG results. The severity of coronary artery stenosis was assessed by the numbers of involved coronary artery branches and the sum of the Gensini scores.

Serum adipocyte fatty acid binding proteins and adiponectin in patients with coronary artery disease: the significance of A-FABP/adiponectin ratio.

Background: Adipocyte fatty acid binding protein (A-FABP) and adiponectin have been shown to play important roles in atherosclerosis. We investigated serum A-FABP, adiponectin and A-FABP/adiponectin ratio in patients with coronary artery disease (CAD).

Methods: A total of 340 subjects who underwent coronary angiography (CAG) were classified into CAD group (n=211) and non-CAD group (n=129) according to the CAG.
