Ensure an "Ultrasound Window" on the Patient's Neck to Evaluate Cerebral Blood Flow!

Thorac Cardiovasc Surg 2021 Jun 15. Epub 2021 Jun 15.

Department of Pediatric Anesthesiology, University Hospital Bonn, Bonn, Germany.

Near-infrared spectroscopy (NIRS) does not provide information about changes in oxygenation in whole-brain areas. Although the branching vessels of the aortic arch are not always easy to identify using transesophageal echocardiography (TEE), the blood flow status of cervical arteries can always be assessed by applying an ultrasound probe via the "ultrasound window" on the patient's neck, which can be ensured by devising alternative insertion approaches of the central venous catheter. This method is very simple but compensates for the limitations of the combination of NIRS and TEE, especially during cardiac surgery with cardiopulmonary bypass management using selective cerebral perfusion.

BCNatal Fetal Medicine Research Center, Hospital Clínic and Hospital Sant Joan de Déu, University of Barcelona, Barcelona, Spain.

Introduction: Preterm prelabor rupture of membranes (PPROM) is a common complication after fetal surgeries. The aim of this study was to assess risk factors for and outcomes after PPROM following cord occlusion (CO) in monochorionic diamniotic (MCDA) pregnancies.

Methods: This was a retrospective cohort study of 188 consecutive MCDA pregnancies treated by bipolar or laser CO, either primarily because of discordant malformation (dMF) or severe selective fetal growth restriction (sFGR), or secondarily when complete bichorionization was not possible in case of twin-to-twin transfusion syndrome (TTTS) or sFGR.

Copy number alterations identify a smoking-associated expression signature predictive of poor outcome in head and neck squamous cell carcinoma.

Cancer Genet 2021 May 28;256-257:136-148. Epub 2021 May 28.

Department of Biochemistry, Program in Cancer Cell Biology USA. Electronic address:

Cigarette smoking is a risk factor for the development of head and neck squamous cell carcinoma (HNSCC), partially due to tobacco-induced large-scale chromosomal copy-number alterations (CNAs). Identifying CNAs caused by smoking is essential in determining how gene expression from such regions impact tumor progression and patient outcome. We utilized The Cancer Genome Atlas (TCGA) whole genome sequencing data for HNSCC to directly identify amplified or deleted genes correlating with smoking pack-year based on linear modeling.

Treg and IL-1 receptor type 2-expressing CD4 T cell-deleted CD4 T cell fraction prevents the progression of age-related hearing loss in a mouse model.

J Neuroimmunol 2021 Jun 8;357:577628. Epub 2021 Jun 8.

Department of Otolaryngology, Head and Neck Surgery, Kansai Medical University, Hirakata, Osaka, Japan.

We investigated the association between cellular immunity and age-related hearing loss (ARHL) development using three CD4 T cell fractions, namely, naturally occurring regulatory T cells (Treg), interleukin 1 receptor type 2-expressing T cells (I1R2), and non-Treg non-I1R2 (nTnI) cells, which comprised Treg and I1R2-deleted CD4 T cells. Inoculation of the nTnI fraction into a ARHL murine model, not only prevented the development of ARHL and the degeneration of spiral ganglion neurons, but also suppressed serum nitric oxide, a source of oxidative stress. Further investigations on CD4 T cell fractions could provide novel insights into the prevention of aging, including presbycusis. Read More

Interactive regulation of laryngeal cancer and neuroscience.

Biochim Biophys Acta Rev Cancer 2021 Jun 12:188580. Epub 2021 Jun 12.

Department of Pathology, Harbin Medical University Cancer Hospital, Harbin 150081, China. Electronic address:

Nerve fibres are distributed throughout the body along with blood and lymphatic vessels. The intrinsic morphological characteristics of nerves and the general characteristics of secretions in the tumour microenvironment provide a solid theoretical basis for exploring how neuronal tissue can influence the progression of laryngeal cancer (LC). The central nervous system (CNS) and the peripheral nervous system (PNS) jointly control many aspects of cancer and have attracted widespread attention in the study of the progression, invasion and metastasis of tumour tissue banks.

Differential diagnosis of acute traumatic hip pain in the elderly.

Acta Orthop Belg 2021 Mar;87(1):1-7

Elderly patients who present with an inability to weight bear following a fall, with normal radiographs, should be appropriately investigated to rule out an occult hip fracture (OHF). We aim to identify both the range and incidence of the differential diagnosis of acute traumatic hip pain in a large series of patients investigated for OHF. A retrospective analysis of consecutive patients investigated for an OHF with magnetic resonance imaging (MRI) was performed. Read More

A Pre-Doctoral Clinical Ethics Fellowship for Medical Students.

J Clin Ethics 2021 ;32(2):165-172

Michigan Medicine, Learning Health Services, 1111 Catherine St., Rm 229, Ann Arbor, Michigan 48109.

Introduction: Despite the need for trained physician ethicists, fellowships in clinical ethics are limited and primarily offered to those who have completed a graduate degree. The standardization of credentialing for clinical ethics consultants (CECs) and the restructuring of undergraduate medical education allow innovative models to train CECs that can provide an expanded opportunity for formal ethics training at an earlier stage.

Methods: At the University of Michigan Medical School we developed, implemented, and evaluated a pre-doctoral clinical ethics fellowship program from 2017 to 2019 for senior medical students, designed to meet established competencies for CECs. Read More

The World Brain Death Project: The More You Say It Does Not Make It True.

J Clin Ethics 2021 ;32(2):97-108

Pediatric Intensive Care Unit, Royal Children's Hospital, 50 Flemington Rd., Parkville, Melbourne, 3052 Australia.

The World Brain Death Project clarified many aspects of the diagnosis of brain death/death by neurologic criteria. Clearer descriptions than previously published were presented concerning the etiology, prerequisites, minimum clinical criteria, apnea testing targets, and indications for ancillary testing. Nevertheless, there remained many epistemic and metaphysical assertions that were either false, ad hoc, or confused. Read More
