Unconventional Anomalous Hall Effect Driven by Self-Intercalation in Covalent 2D Magnet CrTe.

Covalent 2D magnets such as CrTe, which feature self-intercalated magnetic cations located between monolayers of transition-metal dichalcogenide material, offer a unique platform for controlling magnetic order and spin texture, enabling new potential applications for spintronic devices. Here, it is demonstrated that the unconventional anomalous Hall effect (AHE) in CrTe, characterized by additional humps and dips near the coercive field in AHE hysteresis, originates from an intrinsic mechanism dictated by the self-intercalation. This mechanism is distinctly different from previously proposed mechanisms such as topological Hall effect, or two-channel AHE arising from spatial inhomogeneities.

Multi-day vs single-day dexamethasone for the prophylaxis of chemotherapy-induced nausea and vomiting: systematic review and meta-analysis.

Introduction: Over the past decade, several randomized controlled trials have compared single-day dexamethasone (dexamethasone-sparing) regimens to the current standard multi-day dexamethasone antiemetic regimen for chemotherapy-induced nausea and vomiting (CINV). The aim of this systematic review and meta-analysis is to compare the efficacy and safety of dexamethasone-sparing regimens to standard multi-day dexamethasone, used for the prophylaxis of CINV.

Methods: Ovid Medline and Embase were searched from database inception to March 2024.

Unidirectional ray polaritons in twisted asymmetric stacks.

The vast repository of van der Waals (vdW) materials supporting polaritons offers numerous possibilities to tailor electromagnetic waves at the nanoscale. The development of twistoptics-the modulation of the optical properties by twisting stacks of vdW materials-enables directional propagation of phonon polaritons (PhPs) along a single spatial direction, known as canalization. Here we demonstrate a complementary type of directional propagation of polaritons by reporting the visualization of unidirectional ray polaritons (URPs).

Global disparities in cancer supportive care: An international survey.

Background: The global cancer burden is rising, particularly in low- and middle-income countries (LMIC), highlighting a critical research gap in understanding disparities in supportive care access. To address this, the Multinational Association of Supportive Care in Cancer (MASCC) Health Disparities Committee initiated a global survey to investigate and delineate these disparities. This study aims to explore and compare supportive care access disparities between LMIC and High-Income Countries (HIC).

Real-world evidence for patients with advanced -mutated non-small cell lung cancer (NSCLC) in Canada is limited. This study's objective was to use previously validated DARWEN artificial intelligence (AI) to extract data from electronic heath records of patients with non-squamous NSCLC at University Health Network (UHN) to describe mutation prevalence, treatment patterns, and outcomes. Of 2154 patients with NSCLC, 613 had advanced disease.

Perceived Barriers Toward Patient-Reported Outcome Implementation in Cancer Care: An International Scoping Survey.

Purpose: Implementation of patient-reported outcomes (PROs) collection is an important priority in cancer care. We examined perceived barriers toward implementing PRO collection between centers with and without PRO infrastructure and administrators and nonadministrators.

Patients And Methods: We performed a multinational survey of oncology practitioners on their perceived barriers to PRO implementations.

Equity, diversity, and inclusion in the Multinational Association for Supportive Care in Cancer: a global membership survey.

Equity, diversity, and inclusion (EDI) are essential for healthcare organizations since they allow for the development of programs and initiatives that bring together diverse perspectives and knowledge. Global multidisciplinary organizations, such as the Multinational Association for Supportive Care in Cancer (MASCC), need to understand the perspective of their members regarding EDI to identify opportunities to enhance diversity and inclusiveness and to better meet the needs of members from different backgrounds and resources. The MASCC Health Disparities Committee designed a survey to identify issues related to disparities faced by MASCC members when providing supportive care to patients with cancer and to examine the EDI landscape within the organization.

Incidence and survival of secondary malignancies after external beam radiotherapy for prostate cancer in the SEER database.

Introduction: We investigated the incidence of secondary bladder (BCa) and rectal cancers (RCa) after external beam radiotherapy (EBRT) for prostate cancer (PCa) compared to radical prostatectomy (RP) alone, and compared cancer-specific survival (CSS) of these secondary neoplasms to their primary counterparts.

Methods: This retrospective cohort study included men in the SEER cancer registry with a diagnosis of non-metastatic, clinically node-negative PCa treated with either RP or EBRT from 1995-2011 and allowed a minimum five-year lag period for the development of secondary BCa or RCa. Patients were divided into two eras, 1995-2002 and 2003-2011, to examine differences in incidence of secondary malignancies over time.

Comparing transmission- and epi-BCARS: a round robin on solid-state materials.

Broadband coherent anti-Stokes Raman scattering (BCARS) is a powerful spectroscopy method combining high signal intensity with spectral sensitivity, enabling rapid imaging of heterogeneous samples in biomedical research and, more recently, in crystalline materials. However, BCARS encounters spectral distortion due to a setup-dependent non-resonant background (NRB). This study assesses BCARS reproducibility through a round robin experiment using two distinct BCARS setups and crystalline materials with varying structural complexity, including diamond, 6H-SiC, KDP, and KTP.

First impressions: A prospective evaluation of patient-physician concordance and satisfaction following the initial medical oncology consultation.

Background: An especially significant event in the patient-oncologist relationship is the initial consultation, where many complex topics-diagnosis, treatment intent, and often, prognosis-are discussed in a relatively short period of time. This study aimed to measure patients' understanding of the information discussed during their first medical oncology visit and their satisfaction with the communication from medical oncologists.

Methods: Between January and August 2021, patients without prior systemic treatment of their gastrointestinal malignancy (GI) attending the Princess Margaret Cancer Centre (PMCC) were approached within 24 h of their initial consultation to complete a paper-based questionnaire assessing understanding of their disease (diagnosis, treatment plan/intent, and prognosis) and satisfaction with the consultation.

Presentation and outcomes of KRAS mutant non-small cell lung cancer patients with stage IV disease at diagnosis (de novo) versus at recurrence.

Close monitoring after diagnosis of patients with stage I-III non-small cell lung cancer (NSCLC) may result in fitter patients with lower disease burden at the time of metastatic recurrence or progression compared to patients diagnosed initially as stage IV (de novo). We compared the presentation, treatments, and outcomes of patients with KRAS-mutated NSCLC with de novo versus recurrent stage IV disease. Of 109 patients, 94% had a smoking history.

Terahertz Twistoptics-Engineering Canalized Phonon Polaritons.

The terahertz (THz) frequency range is key to studying collective excitations in many crystals and organic molecules. However, due to the large wavelength of THz radiation, the local probing of these excitations in smaller crystalline structures or few-molecule arrangements requires sophisticated methods to confine THz light down to the nanometer length scale, as well as to manipulate such a confined radiation. For this purpose, in recent years, taking advantage of hyperbolic phonon polaritons (HPhPs) in highly anisotropic van der Waals (vdW) materials has emerged as a promising approach, offering a multitude of manipulation options, such as control over the wavefront shape and propagation direction.

Individualized risk assessment of distant metastases in oral cavity carcinoma: a validated predictive-score model.

Background: We aimed to develop and validate a risk-scoring system for distant metastases (DMs) in oral cavity carcinoma (OCC).

Methods: Patients with OCC who were treated at 4 tertiary cancer institutions with curative surgery with or without postoperative radiation/chemoradiation therapy were randomly assigned to discovery or validation cohorts (3:2 ratio). Cases were staged on the basis of tumor, node, and metastasis staging according to the eighth edition of the American Joint Committee on Cancer/Union for International Cancer Control guidelines.

BBC uses a teach-model-coach-review approach, delivered through weekly 15-min virtual meetings with a speech-language pathologist. We discuss accommodations needed for successful virtual follow-up test administration and preliminary assessment outcomes for children with classic galactosemia (CG) and controls at age 2.

Food Allergy Labeling Laws: International Guidelines for Residents and Travelers.

The prevalence of food allergies varies by country, as does each country's food allergen labeling. While labeling laws may vary by country, most follow the Codex Alimentarius. Even developing countries have some degree of labeling guidelines for food allergies, but it is highly developed countries that tend to implement stricter labeling regulations to protect their citizens and tourists.

Néel Skyrmion Bubbles in LaSrMnRuO Multilayers.

Ferromagnetic LaSrMnRuO epitaxial multilayers with controlled variation of the Ru/Mn content were synthesized to engineer canted magnetic anisotropy and variable exchange interactions, and to explore the possibility of generating a Dzyaloshinskii-Moriya interaction. The ultimate aim of the multilayer design is to provide the conditions for the formation of domains with nontrivial magnetic topology in an oxide thin film system. Employing magnetic force microscopy and Lorentz transmission electron microscopy in varying perpendicular magnetic fields, magnetic stripe domains separated by Néel-type domain walls as well as Néel skyrmions smaller than 100 nm in diameter were observed.
