The remarkable success of Graph Neural Networks underscores their formidable capacity to assimilate multimodal inputs, markedly enhancing performance across a broad spectrum of domains. In the context of molecular modeling, considerable efforts have been made to enrich molecular representations by integrating data from diverse aspects. Nevertheless, current methodologies frequently compartmentalize geometric and semantic components, resulting in a fragmented approach that impairs the holistic integration of molecular attributes.

For two decades the ASCO CAP HER2 testing criteria have included 0 and 1+ scores, but this distinction was inconsequential. Now, based on the DESTINY Breast-04 Trial (DB-04) results, for patients with metastatic breast cancer it underpins eligibility for T-DXd treatment. Discerning 0 from 1+ IHC staining is challenging, as HER2 low is not a biologically distinct cancer subset, there are no reference standards or controls and second-tier tests do not apply.

Objectives: Urothelial carcinoma in situ (CIS) with early papillary formation is terminology sometimes used to suggest incipient high-grade papillary urothelial carcinoma (PUC) but may lead to confusion between true CIS and lateral flat spread of PUC.

Methods: It remains unclear how pathologists and urologists interpret this scenario, so a survey was circulated to 68 pathologists (group 1 = 28 academic genitourinary pathologists; group 2 = 17 pathologists with a self-reported genitourinary focus; group 3 = 23 pathologists self-reported as not genitourinary specialists) and 32 urologists.

Results: Regarding atypical urothelial lesions that appear mainly flat but contain possible papillae, group 3 was more likely to label this as CIS compared with groups 1 and 2 (35% for group 3 vs 13% for groups 1 and 2), while groups 1 and 2 more often adopted another descriptive diagnosis, such as "CIS with early papillary features" (38% for groups 1 and 2 vs 13% for group 3).

Background: Internet-delivered cognitive behaviour therapy (ICBT) is an accessible and effective treatment option for post-secondary students, but engagement and completion rates are less favourable than in non-student populations in routine care. Studies on students' treatment preferences suggest that a range of options should be offered. Examining students' engagement and outcomes associated with ICBT course options of varying durations can help inform how to optimally deliver ICBT to university students in routine care.

Pulse (Basel)

November 2024

Department of Biomedical Engineering, Cardiovascular Research Institute Maastricht (CARIM), Maastricht University, Maastricht, The Netherlands.

Introduction: Arterial stiffening is a hallmark of vascular ageing, and unravelling its underlying mechanisms has become a central theme in the field of cardiovascular disease. While various techniques and experimental setups are accessible for investigating biomechanics of blood vessels both in vivo and ex vivo, comparing findings across diverse methodologies is challenging.

Methods: Arterial stiffness in the aorta of adult (5 months) and aged (24 months) wild-type C57Bl/6J mice was measured in vivo, after which ex vivo biomechanical evaluation was performed using the Rodent Oscillatory Tension Setup to study Arterial Compliance (ROTSAC; University of Antwerp, Belgium) and the DynamX setup (Maastricht University, The Netherlands).

Identifying proteins from living organisms helps us understand the biological functions of cells, discover new molecular mechanisms, and interrogate known mechanisms for improving our understanding. For a comprehensive understanding of cellular functions, identifying the whole protein content, or proteome, of a cell is desirable but challenging. Here, we describe in detail two methods of proteome fractionation at either the protein (SDS-PAGE) or peptide (high-pH reversed-phase fractionation) level, which can be used to maximize the identification of proteins from complex biological samples.

Delusional belief about location ("reduplicative paramnesia").

Cogn Neuropsychiatry

December 2024

Emeritus Wilde Professor of Mental Philosophy, Corpus Christi College, Oxford, UK.

Introduction: People admitted to hospital as inpatients following head injury or stroke sometimes form the delusional belief that they are located somewhere else-often, near or in their home. This delusion was first described by Pick, who named it "reduplicative paramnesia"; we argue instead for the term "location delusion".

Methods: We carried out a literature search and identified 112 cases of location delusion published since Pick's original 1903 case.

Anastomotic leakage is a well-understood major complication of colorectal surgery and carries significant implications for patient morbidity and mortality. However, an infected collection fistulating through an otherwise healthy colorectal anastomosis can mimic an anastomotic leak and warrants different management to a primary anastomotic leak. Such a presentation is undocumented in the current literature.

Clin Chim Acta

December 2024

Department of Medicine, University of Adelaide, Australia; Endocrine and Metabolic Unit, Royal Adelaide Hospital, Australia; Endocrine and Diabetes Services, The Queen Elizabeth Hospital, Australia.

Background: Corticosteroid-binding globulin (CBG) modulates tissue cortisol availability via modification of cortisol:CBG binding affinity in response to multiple factors, including neutrophil elastase (NE) cleavage of the reactive centre loop (RCL), converting high affinity CBG (haCBG) to low affinity CBG (laCBG). In vitro, glycosylation of the RCL at Asn347 affects NE cleavage susceptibility. To date, no direct measurement of laCBG, which would verify NE cleavage, has been reported.
