Sulfonated White-Graphene for High-Performance Gel Polymer Electrolytes: The Interplay between Ion Conductivity and Rheology.

Research into flexible solid-state supercapacitors for wearable electronics focuses on achieving high performance and safety. Gel polymer electrolytes (GPEs) are preferred over fully solid-state electrolytes due to their better ionic conductivity while addressing safety concerns associated with liquid electrolytes. This study aims to enhance high-performance gel polymer electrolytes (HP-GPEs) by improving the ion transfer rate of polyvinyl alcohol (PVA) with sulfonated hexagonal boron nitride (known as white-graphene) and exploring how rheology influences ion-conduction within HP-GPEs.

The use of diagnostic complex robotic-assisted segmentectomy in the management of incidental and screen-detected pulmonary nodules.

Objectives: Robotic-assisted thoracoscopic surgery (RATS) facilitates complex pulmonary segmentectomy which offers one-stage diagnostic and therapeutic management of small pulmonary nodules. We aimed to explore the potential advantages of a faster, simplified pathway and earlier diagnosis against the disadvantages of unnecessary morbidity in benign cases.

Methods: In an observational study, patients with small, solitary pulmonary nodules deemed suspicious of malignancy by a multidisciplinary team were offered surgery without a pre or intraoperative biopsy.

Predictors of outcome in diabetic patients undergoing infrapopliteal endovascular revascularization for chronic limb-threatening ischemia.

Objective: The incidence of chronic limb-threatening ischemia in diabetic patients is increasing. The factors influencing outcome after infrapopliteal revascularization in these patients are largely unknown. Therefore, this study aims to identify the impact of perioperative glucose control on the long-term outcomes in this patient cohort, and furthermore to identify other factors independently associated with outcome.

Maintaining safe lung cancer surgery during the COVID-19 pandemic in a global city.

Background: SARS-CoV-2 has challenged health service provision worldwide. This work evaluates safe surgical pathways and standard operating procedures implemented in the high volume, global city of London during the first wave of SARS-CoV-2 infection. We also assess the safety of minimally invasive surgery(MIS) for anatomical lung resection.

Thoracic Surgery during Coronavirus Disease 2019 (COVID-19): The Experience of a Level 1 Trauma Center.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus primarily affecting the respiratory system, was initially diagnosed in Wuhan, China, in late 2019. Identified as coronavirus disease 2019 (COVID-19) by the World Health Organization, the virus rapidly became a global pandemic. The effects on health care worldwide were unprecedented as countries adapted services to treat masses of critically ill patients.

The relationship between maternal characteristics and carotid intima-media thickness using an automated ultrasound technique.

To investigate CIMT and its relationship with maternal demographic characteristics in healthy pregnancy. CIMT was measured using an au. CIMT showed no relationship with gestational age (rho=-0.

Pelvic floor examination performed by medical students: a model to obtain consent.

Student-led clinical examinations, including pelvic floor examinations, are an integral part of clinical training and can be beneficial to both students and patients alike. However, our experience and previous literature catalog numerous obstacles in obtaining consent for student-led pelvic floor examinations. Although some of these factors may not be modifiable, it is evident that efforts can be made to overcome those that are.

Comparison of minimally invasive direct coronary artery bypass and drug-eluting stents for management of isolated left anterior descending artery disease: a systematic review and meta-analysis of 7,710 patients.

Background: In the contemporary era of drug-eluting stents (DES) the issue of optimal revascularization strategy for patients with isolated disease of the left anterior descending (LAD) artery has gained more significance. We aimed to evaluate the current best evidence on the subject by performing a systematic review and meta-analysis of the studies comparing minimally invasive direct coronary artery bypass (MIDCAB) grafting with DES in patients with isolated LAD disease.

Methods: A literature search was conducted from 1966 through March 2018 using MEDLINE, EMBASE, and other scientific databases to identify relevant articles.

Emergency Department Resource Use in Pediatric Pneumonia: Point-of-Care Lung Ultrasonography versus Chest Radiography.

Objectives: Point-of-care lung ultrasonography (US) is an alternative to chest radiography for imaging of suspected community-acquired pneumonia (CAP) in children. We compared pediatric emergency department (ED) time metrics between children who received point-of-care lung US versus chest radiography. Secondary objectives were comparisons of health system costs and other resources in these imaging groups.
