Viral contamination on the surfaces of the personal protective equipment among health care professionals working in COVID-19 wards: A single-center prospective, observational study.

Objective: To evaluate potential viral contamination on the surfaces of personal protective equipment (PPE) in COVID-19 wards.

Methods: Face shields, gloves, the chest area of PPE and shoe soles were sampled at different time points. The samples were tested for the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by PCR, and the cycle threshold (CT) values were recorded.

Whether the start time of elective lung surgery impacts perioperative outcomes and cost?

Background: Fatigue and the long work hours of surgeons have attracted increasing concern in recent years. We aimed to explore whether starting time was associated with perioperative outcomes and cost for elective lung surgery.

Methods: A retrospective study was conducted on elective lung surgery patients at a high surgery-volume center between September 2019 and November 2019.

Surgical Treatment for Esophageal Leiomyoma: 13 Years of Experience in a High-Volume Tertiary Hospital.

Background: Esophageal leiomyoma is the most common benign tumor in the esophagus. Thoracotomy and thoracoscopy are both elective for esophageal leiomyoma enucleation. This study aimed at presenting surgical experience in our center and exploring more suitable surgical methods for different situations.

Correlation of Homocysteine, AHSG, CRP with Insulin Resistance, 25-(OH)2-VitD, Blood Lipids in Gestational Diabetes Patients.

Background: To investigate the correlations of serum homocysteine (Hcy), α2-Heremans-Schmid glycoprotein (AHSG), and C-reactive protein (CRP) with insulin resistance (IR), 25-hydroxyvitamin D (25-OH-VD), and blood lipids in patients with gestational diabetes mellitus (GDM) by detecting their levels.

Methods: A total of 72 GDM patients (GDM group) and 72 healthy pregnant women (control group) delivered in our hospital from February 2017 to January 2019 were randomly selected. The basic data, somatological parameters [height, weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio (WHR), blood pressure, and body fat content], and biochemical indexes (glucose metabolism indexes, lipid metabolism indexes, Hcy, AHSG, CRP, and 25-OH-VD) were compared between the two groups.

Comparative Effect of Propofol and Volatile Anesthetics on Postoperative Pulmonary Complications After Lung Resection Surgery: A Randomized Clinical Trial.

Background: The effect of general anesthetics (propofol and volatile anesthetics) on pulmonary outcome after lung resection surgery with one-lung ventilation (OLV) is yet undetermined. We evaluated the effect of intravenous anesthesia (propofol) and volatile anesthesia (sevoflurane or desflurane) regimens on postoperative pulmonary complications (PPCs) in patients undergoing lung resection surgery.

Methods: This prospective, randomized controlled trial enrolled 555 adult patients scheduled for lung resection surgery with OLV.

[Higher-order aberrations in myopic and astigmatism eyes].

Objective: To analyze the distribution of the higher order aberrations in the population of Chinese with myopia and astigmatism and determine whether the pupil size, degree of myopia and astigmatism affects the higher order aberrations.

Methods: Using a Tscherning method, 147 myopic and astigmatism eyes were evaluated before LASIK. The root mean square (RMS) values of higher order aberrations for each subject with pupil diameters of 4.
