Despite the acknowledged merits of precision oncology (PO) and its increasing global implementation, its full potential for advancing care and prevention remains unrealized. The benefits are currently accessible to only limited patient segments because of multifaceted barriers. Successful implementation hinges on various factors-scientific complexities not limited to technical, clinical, regulatory, economic, administrative, and health care policy-related challenges.

Intrinsic Mechanical Effects on the Activation of Carbon Catalysts.

J Am Chem Soc

January 2025

CAS Key Laboratory of Nanosystem and Hierarchical Fabrication, National Center for Nanoscience and Technology (NCNST), Beijing 100190, China.

The mechanical effects on carbon-based metal-free catalysts (C-MFCs) have rarely been explored, despite the global interest in C-MFCs as substitutes for noble metal catalysts. Stress is ubiquitous, whereas its dedicated study is severely restricted due to its frequent entanglement with other structural variables, such as dopants, defects, and interfaces in catalysis. Herein, we report a proof-of-concept study by establishing a platform to continuously apply strain to a highly oriented pyrolytic graphite (HOPG) lamina, simultaneously collecting electrochemical signals.

Purpose: To assess the practice patterns among the Indian Pediatric Glaucoma Society (IPGS) members in the management of children with primary congenital glaucoma (PCG).

Methods: An anonymous 74-question survey was administered online via Qualtrics (Qualtrics, Provo, Utah, USA) using a link sent by email to the 88 IPGS members. The questionnaire comprised five sections and was designed to gather information regarding respondent demographics and specialty training, clinic composition and volume, surgical practices and preferences, follow-up practices, and additional services.

The involvement of service-users, clinicians, and other health service end-users is recognised as an essential part of health and medical research. This collaborative approach can significantly contribute to methodological advancements including the development of research instruments and measures that ensure their suitability for research participants. The current paper details the co-design, development and implementation of the novel, digitised COGwheel (Co-designed Outcomes for Guests Evaluation Wheel).

Introduction: Reference ranges for determining pathological versus normal postoperative return of bowel function are not well characterised for general surgery patients. This study aimed to characterise time to first postoperative passage of stool after general surgery; determine associations between clinical factors and delayed time to first postoperative stool; and evaluate the association between delay to first postoperative stool and prolonged length of hospital stay.

Methods: This study included consecutive admissions at two tertiary hospitals across a two-year period whom underwent a range of general surgery operations.

Arcuate fasciculus cortico-cortical evoked potentials and direct cortico-subcortical stimulation during awake craniotomy for debulking of left dominant temporal oligodendroglioma.

Neurosurg Focus Video

January 2025

Flinders Health and Medical Research Institute, College of Medicine and Public Health, Flinders University, Adelaide, South Australia; and.

Electrophysiological mapping and monitoring techniques permit the objective measurement of eloquent cortical regions and accompanying white matter tracts to reduce the incidence of iatrogenic injury in glioma surgery. Recently, there has been increased interest in mapping and monitoring of the human arcuate fasciculus via cortico-cortical evoked potentials (CCEPs) during awake and asleep craniotomy. The authors present the case of a 27-year-old female who underwent a hypnosis-assisted awake craniotomy with cortico-subcortical language mapping and arcuate fasciculus CCEPs.

Heart failure with preserved ejection fraction (HFpEF) is defined by heart failure (HF) with a left ventricular ejection fraction (LVEF) of at least 50%. HFpEF has a complex and heterogeneous pathophysiology with multiple co-morbidities contributing to its presentation. Establishing the diagnosis of HFpEF can be challenging.

Aims: The sodium-glucose cotransporter 2 inhibitor canagliflozin reduces the risk of heart failure (HF) hospitalization or cardiovascular death and chronic kidney disease (CKD) progression among patients with type 2 diabetes at high cardiovascular risk or with CKD. Patients with type 2 diabetes commonly have coexisting HF or CKD that require treatment with loop diuretics; however, the prognostic implications of oral loop diuretic intensification are not well characterized.

Methods And Results: In this participant-level pooled analysis of the CREDENCE and CANVAS trials (not including CANVAS-R), 1454/8731 (16.

Objectives: Despite practice development in the area of advanced care planning (ACP) and systems wide changes implemented to support ACP processes, there has been a paucity of research which has addressed the experiences of a key stakeholder group - family and carers - as they navigate their way through these often very challenging processes. The study described in this article focussed on this key group.

Methods: In-depth qualitative interviews were undertaken with family members and carers in a regional area of Australia in order to illuminate their lived experiences of ACP processes.

Sci Data

January 2025

Centre for Ecosystem Science, School of Biological, Earth, and Environmental Sciences, University of New South Wales, Sydney, NSW 2052, Australia.

Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity, deliver essential ecosystem services and contribute to planetary stability. We present Antarctica's first comprehensive ecosystem classification and map of ice-free lands, which host most of the continent's biodiversity.

Introduction: Early pregnancy care involves the screening and identification of women with risk factors for adverse pregnancy outcomes, including stillbirth or preterm birth, to tailor pregnancy care and interventions accordingly. Most stillbirths and approximately two-thirds of preterm births, however, occur in the absence of evident risk factors. The majority of stillbirths occur in the preterm period, yet there are few interventions targeting this period, and progress to reduce stillbirth rates remains slow.
