The theoretical mortality risk of an asymptomatic patient with a negative SARS-CoV-2 test developing COVID-19 following elective orthopaedic surgery.

Bone Joint J 2020 Jul 6:1-5. Epub 2020 Jul 6.

South West London Elective Orthopaedic Centre, UK; Northumbria University, Newcastle upon Tyne, Tyne and Wear, Epsom, UK.

Aims: The risk to patients and healthcare workers of resuming elective orthopaedic surgery following the peak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been difficult to quantify. This has prompted governing bodies to adopt a cautious approach that may be impractical and financially unsustainable. The lack of evidence has made it impossible for surgeons to give patients an informed perspective of the consequences of elective surgery in the presence of SARS-CoV-2. Read More

Plasma Metabolic Profiling of Human Thyroid Nodules by Gas Chromatography-Mass Spectrometry (GC-MS)-Based Untargeted Metabolomics.

Front Cell Dev Biol 2020 16;8:385. Epub 2020 Jun 16.

Cellular and Molecular Endocrine Research Center, Research Institute for Endocrine Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

One of the challenges in the area of diagnostics of human thyroid cancer is a preoperative diagnosis of thyroid nodules with indeterminate cytology. Herein, we report an untargeted metabolomics analysis to identify circulating thyroid nodule metabolic signatures, to find new novel metabolic biomarkers. Untargeted gas chromatography-quadrupole-mass spectrometry was used to ascertain the specific plasma metabolic changes of thyroid nodule patients, which consisted of papillary thyroid carcinoma (PTC; = 19), and multinodular goiter (MNG; = 16), as compared to healthy subjects ( = 20).

Radiological Identification of Injury to the Kaplan Fibers of the Iliotibial Band in Association With Anterior Cruciate Ligament Injury.

Am J Sports Med 2020 Jun 24:363546520931854. Epub 2020 Jun 24.

OrthoSport Victoria Research Unit, Richmond, Australia.

Background: Recent biomechanical studies have demonstrated that the Kaplan fibers (KFs) of the iliotibial band play a role in the control of anterolateral rotation of the knee. However, controversy exists regarding whether the KFs are injured in conjunction with anterior cruciate ligament (ACL) injury.

Anesthesia for meningioma surgery.

Handb Clin Neurol 2020 ;169:285-295

Department of Anesthesia & Perioperative Care, University of California San Francisco, San Francisco, CA, United States.

Patients receiving treatment for a meningioma require anesthesia when undergoing open craniotomy and, in some cases, during preoperative tumor embolization and radiosurgery. Adequate anesthesia management is integral to patients' perioperative care, which consists of the three phases of preoperative assessment and optimization, intraoperative care, and postoperative recovery. The preoperative anesthesia evaluation focusses on the cardiorespiratory and neurologic systems, as well as the airway, but also extends to ensure the optimal treatment of significant comorbidities before surgical intervention.

Preoperative nuclear stress testing in the very old patient population.

World J Cardiol 2020 May;12(5):210-219

Department of Cardiology, Northwell Health, New Hyde Park, NY, 11042, United States.

Background: Elderly patients awaiting moderate to high-risk surgery may undergo nuclear stress testing (NST) in order to evaluate their cardiovascular risk. The prognostic utility of such testing in the very elderly (≥ 85 years) has yet to be fully evaluated. Octogenarians and nonogenarians frequently have a number of concurrent conditions including a high rate of coronary disease, and therefore the prognostic value of NST for their preoperative risk assessment has been questioned.

Dental Specialty Center, Brazilian Military Police, Minas Gerais, Brazil.

Introduction: The aim of this investigation was to evaluate the effect of the presence and preparation of middle mesial (MM) canals on the fracture resistance of the mesial root of mandibular molars.

Methods: Forty intact mesial roots of mandibular first molars having two (n=20) or three (n=20) independent canals from the furcation level for up to at least 5 mm apically were selected based on preoperative micro-CT scanning. The selected roots were then distributed into two experimental (n=10) and two control groups (n=10), according to root length, canal configuration (2 or 3 independent canals), and root thickness at the furcation level.

Experimental Model of Zygomatic and Mandibular Defects to Support the Development of Custom Three-Dimensional--Printed Bone Scaffolds.

J Craniofac Surg 2020 Jul-Aug;31(5):1488-1491

Division of Plastic and Reconstructive Surgery, Department of Surgery, Louisiana State University Health Sciences Center, New Orleans, LA.

Introduction: Autologous reconstruction of segmental craniomaxillofacial bone defects is limited by insufficient graft material, donor site morbidity, and need for microsurgery. Reconstruction is challenging due to the complex three-dimensional (3D) structure of craniofacial skeleton. Customized 3D-printed patient-specific biologic scaffolds hold promise for reconstruction of the craniofacial skeleton without donor site morbidity. Read More

Cardiorespiratory fitness fails to predict short-term postoperative mortality in patients undergoing elective open surgery for abdominal aortic aneurysm.

Ann R Coll Surg Engl 2020 Jun 15:1-4. Epub 2020 Jun 15.

Department of Surgery, University Hospital of Wales, Cardiff, Wales, UK.

Introduction: Preoperative cardiopulmonary exercise testing aids surgical risk stratification and is an established predictor of mid- to long-term survival in patients undergoing elective open abdominal aortic aneurysm repair. Whether cardiopulmonary exercise testing also predicts 30-day mortality in this population remains to be established.

Materials And Methods: Data for 109 patients (mean age 72 years) who underwent cardiopulmonary exercise testing to assess risk for surgical abdominal aortic aneurysm repair was analysed. Read More

Pediatric Posterior Fossa Medulloblastoma: The Role of Diffusion Imaging in Identifying Molecular Groups.

J Neuroimaging 2020 Jun 12. Epub 2020 Jun 12.

Department of Diagnostic Imaging, St. Jude Children's Research Hospital, Memphis, TN.

Background And Purpose: The molecular groups WNT activated (WNT), Sonic hedgehog activated (SHH), group 3, and group 4 are biologically and clinically distinct forms of medulloblastoma. We evaluated apparent diffusion coefficient (ADC) values' utility in differentiating/predicting medulloblastoma groups at the initial diagnostic imaging evaluation and prior to surgery.

Methods: We retrospectively measured the ADC values of the enhancing, solid portion of the tumor (EST) and of the whole tumor (WT) and performed Kruskal-Wallis testing to compare the absolute tumor ADC values and cerebellar and thalamic ratios of three medulloblastoma groups (WNT, SHH, and group 3/group 4 combined).
