Background: Herbal supplements are commonly used, however, their side-effect profiles are poorly understood and not subject to the same scrutiny as prescribed medications. Some herbal supplements such as St Johns' Wort are accepted to interfere with clotting pathways, however others, including Red Clover have theoretical bleeding risks based on coumarin content with very little underlying evidence. Case Description: This case reports a 65-year-old woman who suffered a spontaneous acute-on-chronic subdural hemorrhage with a significant postoperative re-hemorrhage...

BACKGROUND AND PURPOSE: The mechanosensitive Piezo1 channel has important roles in vascular physiology and disease. Yoda1 is a small-molecule agonist but the pharmacology of these channels is otherwise limited. EXPERIMENTAL APPROACH: Yoda1 analogues were generated by synthetic chemistry. Intracellular Ca2+ and Tl+ measurements were made in HEK 293 or CHO cell lines overexpressing channel subunits and in human umbilical vein endothelial cells (HUVECs) which natively express Piezo1...

Shoulder pain is a common musculoskeletal complaint that is difficult to treat because of the biomechanical complexity of the shoulder region, the interplay between mobility and stability, and the vital role played by the shoulder in moving, positioning, and providing stability for hand function. Despite advances in biomechanics and pain science, there is still much to learn about how impairments influence shoulder function and health. One impairment, posterior shoulder tightness (PST), is often noted in individuals with shoulder pain and consequently has generated much discussion and debate in recent years...

We experimentally demonstrate topological edge states arising from the valley-Hall effect in two-dimensional honeycomb photonic lattices with broken inversion symmetry. We break the inversion symmetry by detuning the refractive indices of the two honeycomb sublattices, giving rise to a boron nitridelike band structure. The edge states therefore exist along the domain walls between regions of opposite valley Chern numbers. We probe both the armchair and zigzag domain walls and show that the former become gapped for any detuning, whereas the latter remain ungapped until a cutoff is reached...

We present our work investigating the feasibility of combining intraoperative ultrasound for brain shift correction and augmented reality (AR) visualization for intraoperative interpretation of patient-specific models in image-guided neurosurgery (IGNS) of brain tumors. We combine two imaging technologies for image-guided brain tumor neurosurgery. Throughout surgical interventions, AR was used to assess different surgical strategies using three-dimensional (3-D) patient-specific models of the patient's cortex, vasculature, and lesion...

Breast cancer is the most common cancer among women worldwide and ranks second in terms of overall cancer deaths. One of the difficulties associated with treating breast cancer is that it is a heterogeneous disease with variations in benign and pathologic tissue composition, which contributes to disease development, progression, and treatment response. Many of these phenotypes are uncharacterized and their presence is difficult to detect, in part due to the sparsity of methods to correlate information between the cellular microscale and the whole-breast macroscale...

Very little is known about how the adaptive immune system responds to clonal evolution and tumor heterogeneity in non-small cell lung cancer. We profiled the T-cell receptor β complementarity determining region 3 in 20 patients with fully resected non-small cell lung cancer primary lesions and paired brain metastases. We characterized the richness, abundance and overlap of T cell clones between pairs, in addition to the tumor mutation burden and predicted neoantigens. We found a significant contraction in the number of unique T cell clones in brain metastases compared to paired primary cancers...

Improvements in cancer survival mean that long-term toxicities, which contribute to the morbidity of cancer survivorship, are being increasingly recognized. Late adverse effects (LAEs) in normal tissues after radiotherapy (RT) are characterized by vascular dysfunction and fibrosis causing volume loss and tissue contracture, for example, in the free flaps used for immediate breast reconstruction after mastectomy. We evaluated the efficacy of lentivirally delivered superoxide dismutase 2 (SOD2) overexpression and connective tissue growth factor (CTGF) knockdown by short hairpin RNA in reducing the severity of LAEs in an animal model of free flap LAEs...

Background: When safe to do so, avoiding blood transfusions in cardiac surgery can avoid the risk of transfusion-related infections and other complications while protecting a scarce resource and reducing costs. This protocol describes a kidney substudy of the Transfusion Requirements in Cardiac Surgery III (TRICS-III) trial, a multinational noninferiority randomized controlled trial to determine whether the risk of major clinical outcomes in patients undergoing planned cardiac surgery with cardiopulmonary bypass is no greater with a restrictive versus liberal approach to red blood cell transfusion...

PURPOSE: We undertook a study to observe in detail the primary care interactions and communications of patients with newly diagnosed diabetes over time. In addition, we sought to identify key points in the process where miscommunication might occur. METHODS: All health interactions of 32 patients with newly diagnosed type 2 diabetes were recorded and tracked as they moved through the New Zealand health care system for a period of approximately 6 months. Data included video recordings of patient interactions with the health professionals involved in their care (eg, general practitioners, nurses, dietitians)...

BACKGROUND: We sought to explore the perspective of older breast cancer survivors (BCS) from diverse racial and socioeconomic backgrounds toward physical activity (PA) to inform the design of a PA program that fosters acceptability. METHODS: Participants included sixty women, ≥65years, within two years of treatment completion for stage I-III breast cancer. We purposely sampled ≥ten patients in each race [African-American (AA) and Non-Hispanic White (NHW)] and socioeconomic status (SES) [SES disadvantaged and SES non-disadvantaged] group...

When a two-dimensional (2D) electron gas is placed in a perpendicular magnetic field, its in-plane transverse conductance becomes quantized; this is known as the quantum Hall effect. It arises from the non-trivial topology of the electronic band structure of the system, where an integer topological invariant (the first Chern number) leads to quantized Hall conductance. It has been shown theoretically that the quantum Hall effect can be generalized to four spatial dimensions, but so far this has not been realized experimentally because experimental systems are limited to three spatial dimensions...

Weight loss can be achieved through a variety of modalities, but long-term maintenance of lost weight is much more challenging. Obesity interventions typically result in early weight loss followed by a weight plateau and progressive regain. This review describes current understanding of the biological, behavioral, and environmental factors driving this near-ubiquitous body weight trajectory and the implications for long-term weight management. Treatment of obesity requires ongoing clinical attention and weight maintenance-specific counseling to support sustainable healthful behaviors and positive weight regulation...
