Article Synopsis
  • The introduction of immune checkpoint blockade (ICB) has greatly improved treatment outcomes for advanced melanoma, but many patients still become resistant to it due to unclear reasons.
  • Although combining different ICB therapies has been shown to enhance response rates, it also comes with increased toxicity for patients.
  • An analysis of tumor samples from ICB-naïve patients revealed that high genomic heterogeneity and low ploidy can identify those who are intrinsically resistant to aPD-1, leading to a predictive model that may help tailor treatment strategies.

Inhibitors of NQO2 (NRH: quinone oxidoreductase) have potential application in several areas of medicine and pharmacology, including cancer, neurodegeneration (PD and AD), stroke, and diabetes. Here, resveratrol, a known inhibitor of NQO2, was used as the lead by replacing the double bond in resveratrol with a benzothiazole scaffold. Fifty-five benzothiazoles were designed as NQO2 inhibitors and synthesized, comprising five benzothiazole series with 3,5-dimethoxy, 2,4-dimethoxy, 2,5-dimethoxy, 3,4-dimethoxy, and 3,4,5-trimethoxy substituents, the key synthetic step being a Jacobson cyclisation with the appropriate thiobenzamide.

Purpose: To evaluate the survival benefit of chemotherapy intensification in older patients with AML who have not achieved a measurable residual disease (MRD)-negative remission.

Methods: Five hundred twenty-three patients with AML (median age, 67 years; range, 51-79) without a flow cytometric MRD-negative remission response after a first course of daunorubicin and AraC (DA; including 165 not in remission) were randomly assigned between up to two further courses of DA or intensified chemotherapy-either fludarabine, cytarabine, granulocyte colony-stimulating factor and idarubicin (FLAG-Ida) or DA with cladribine (DAC).

Results: Overall survival (OS) was not improved in the intensification arms (DAC DA: hazard ratio [HR], 0.

Background: Apathy is a prevalent and debilitating neuropsychiatric symptom among persons living with Alzheimer's disease and related dementias, particularly those residing in long-term care facilities (LTCF). Despite its profound effects on the quality of life for both residents and their caregivers, apathy remains underrecognized and poorly understood in the context of dementia care.

Objective: To investigate the prevalence and biopsychosocial characteristics of apathy among newly admitted residents with dementia in Canadian LTCF using an Apathy Index derived from the interRAI Minimum Data Set (MDS) 2.

Article Synopsis
  • Integrin alpha V is crucial for cell adhesion and signaling during development, and mutations in its gene (ITGAV) can lead to serious health issues.
  • In three families, biallelic variants were found that caused either dysfunctional protein production or the integrin being misplaced, resulting in severe developmental problems like eye and brain abnormalities, inflammatory bowel disease, and immune issues.
  • Studies in patient cells and zebrafish models confirmed these mutations resulted in impaired immune signaling and developmental defects, linking the ITGAV variants to a newly identified human disease.

Background: Dental disease is a common but often under-recognised condition in horses, possibly due to an inability to recognise clinical signs of oral discomfort. Some dental disorders are reportedly more painful than others, but there is no current metric by which dental pain can be objectively assessed. This study aimed to determine whether a facial expression-based pain scale offered an objective and reliable method for assessing dental pain in horses.

Article Synopsis
  • Over the past two decades, there has been a growing focus on diagnosing and managing inner ear schwannomas, especially regarding hearing rehabilitation through cochlear implants, but the terminology used to classify these tumors has been inconsistent and complex.
  • At the Ninth Quadrennial Conference in May 2023 in Bergen, Norway, experts reached a consensus to standardize terminology, ultimately agreeing on the term "inner ear schwannoma (IES)" to clearly describe tumors affecting the eighth nerve in the cochlea, vestibule, or semicircular canals.
  • The newly established classifications break down these tumors into three complexity levels: low (intravestibular, intracochlear), intermediate (with internal

The NLRP3 inflammasome is a key target for drug discovery due to its implication in a range of inflammation-related diseases. In this work, we identify new inhibitors of the NLRP3 inflammasome via a hierarchical virtual screening strategy using molecular similarity, docking and MD simulation. The most potent inhibitors identified from a subsequent biological assay (IC of 1 - 4 μM) feature a sulfonamide group, a motif known to favour NLRP3 inhibition, in conjunction with an indole, benzofuran or tricyclic 6,7-dihydro-5H-indeno[5,6-b]furan ring, yielding novel scaffolds.

Background: Effects of neutering on bitch health have been reported, and are suggested to relate to bitch age at the time of neutering for some diseases. However, variation between published studies in terms of study populations and methodologies makes comparison and consolidation of the evidence difficult.

Objective: A scoping review was designed to systematically search the available literature to identify and chart the evidence on the effect of neutering timing in relation to puberty on five health outcomes: atopy, developmental orthopaedic disease (DOD), neoplasia, obesity and urogenital disease.

Article Synopsis
  • - The study focuses on older patients (over 60 years) with acute myeloid leukemia (AML) and aims to create a prognostic model to identify those who would benefit from intensive chemotherapy and stem cell transplantation.
  • - Researchers analyzed data from 1,910 patients, using a random survival forest to evaluate clinical and genetic factors associated with overall survival, resulting in the identification of four distinct survival groups based on nine variables.
  • - The newly developed AML60+ classification shows improved prognostic accuracy and indicates that intermediate- and very poor-risk patients may benefit from allogeneic hematopoietic cell transplantation, potentially guiding treatment decisions for older adults with AML.

Background: Most schwannomas are isolated tumours occurring in otherwise healthy people. However, bilateral vestibular schwannomas (BVS) or multiple non-vestibular schwannomas indicate an underlying genetic predisposition. This is most commonly -related schwannomatosis (SWN), but when BVS are absent, this can also indicate -related or -related SWN.
