According to the Projective Consciousness Model (PCM), in human spatial awareness, 3-dimensional projective geometry structures information integration and action planning through perspective taking within an internal representation space. The way different perspectives are related to and transform a world model defines a specific perception and imagination scheme. In mathematics, such a collection of transformations corresponds to a 'group', whose 'actions' characterize the geometry of a space.

Importance: Some patients worldwide are asked to acquire an anti-vascular endothelial growth factor (anti-VEGF) agent from a pharmacy, store it, and then bring it to a physician for intravitreal injection (IVT). Anti-VEGF agents must be stored in the refrigerator to avoid bacterial contamination or denaturation. Some cases of severe intraocular inflammation have been reported following IVT of more recently approved anti-VEGF agents, which might be explained by thermal instability.

Harnessing deep learning to detect bronchiolitis obliterans syndrome from chest CT.

Commun Med (Lond)

January 2025

Division of Pulmonary Medicine, Department of Medicine, Lausanne University Hospital (CHUV), University of Lausanne (UNIL), Lausanne, Switzerland.

Background: Bronchiolitis Obliterans Syndrome (BOS), a fibrotic airway disease that may develop after lung transplantation, conventionally relies on pulmonary function tests (PFTs) for diagnosis due to limitations of CT imaging. Deep neural networks (DNNs) have not previously been used for BOS detection. This study aims to train a DNN to detect BOS in CT scans using an approach tailored for low-data scenarios.

Recombinant adeno-associated virus (rAAV) has emerged as the vector of choice for in vivo gene delivery, with numerous clinical trials underway for the treatment of various human diseases. Utilizing rAAV in gene therapy requires a highly precise quantification method to determine the viral genome titer and further establish the optimal therapeutic dosage for a rAAV product. The conventional single-channel droplet digital PCR (1D ddPCR) method offers only partial information regarding the viral vector genome titer, lacking insights into its integrity.

A dataset for evaluating clinical research claims in large language models.

Sci Data

January 2025

Department of Radiology and Medical Informatics, Faculty of Medicine, University of Geneva, Geneva, Switzerland.

Large language models (LLMs) have the potential to enhance the verification of health claims. However, issues with hallucination and comprehension of logical statements require these models to be closely scrutinized in healthcare applications. We introduce CliniFact, a scientific claim dataset created from hypothesis testing results in clinical research, covering 992 unique interventions for 22 disease categories.

Contribution of hypoxia-inducible factor 1alpha to pathogenesis of sarcomeric hypertrophic cardiomyopathy.

Sci Rep

January 2025

Department of Congenital Heart Defects and Pediatric Cardiology, German Heart Center Munich, TUM University Hospital, School of Medicine & Health, Technical University of Munich, Munich, Germany.

Hypertrophic cardiomyopathy (HCM) caused by autosomal-dominant mutations in genes coding for structural sarcomeric proteins, is the most common inherited heart disease. HCM is associated with myocardial hypertrophy, fibrosis and ventricular dysfunction. Hypoxia-inducible transcription factor-1α (Hif-1α) is the central master regulators of cellular hypoxia response and associated with HCM.

Transport and inhibition of the sphingosine-1-phosphate exporter SPNS2.

Nat Commun

January 2025

Centre for Medicines Discovery, Nuffield Department of Medicine, University of Oxford, Oxford, UK.

Sphingosine-1-phosphate (S1P) is a signaling lysolipid critical to heart development, immunity, and hearing. Accordingly, mutations in the S1P transporter SPNS2 are associated with reduced white cell count and hearing defects. SPNS2 also exports the S1P-mimicking FTY720-P (Fingolimod) and thereby is central to the pharmacokinetics of this drug when treating multiple sclerosis.

Case: Triple pelvic osteotomy (TPO) is used to treat developmental dysplasia of the hip in a pediatric population. This case report highlights a new indication for this procedure. Acetabular coverage was restored in a 9-year-old patient who experienced instability following hip hemiarthroplasty and proximal femur composite allograft implantation for the treatment of Ewing sarcoma.

Background: Several single race events (5 km, 10 km, half-marathon, marathon, ultra-marathon) in different countries and different years have been analyzed in multiple studies, representing the rising interest in endurance-based activity and thus physical health. With focus on participation numbers, performance or sex difference, many single study results were obtained. The running trends in a whole country covering a longer period of time and several race distances are missing so far.

The role of anthracyclines in the treatment of early breast cancer (EBC) is increasingly being challenged, especially in de-escalation strategies. However, owing to their immunogenic effects, anthracyclines are promising combination partners with immunotherapies. In the randomized phase 2 trial ABCSG-52 (EudraCT no.

Introduction: Children with septo-optic-pituitary dysplasia (SOD) may experience a range of visual impairments and hormonal dysfunctions beyond developmental delay/intellectual disability. The literature describes sleep fragmentation, circadian rhythm disruptions and reduced sleep efficiency. These manifestations are believed to be closely linked to both structural and functional abnormalities associated with SOD, potentially disrupting the natural circadian rhythm.

Background: Presentations and outcomes of acute myocardial infarction (MI) differ between women and men, with the worst outcomes being reported in younger women. Mental stress induced ischemia and sympathetic activation have been suggested to play a prominent role in the pathogenesis of MI in younger women, however, the impact of sex hormones on these parameters remains unknown.

Methods: The effect of sex hormones and age on myocardial infarct size and myocardial sympathetic activity (MSA) was assessed in male and female, as well as young (4-6 months) and aged (20-22 months) FVB/N mice (n = 106, 60 gonadectomized and 46 sham-operated animals) who underwent in vivo [C]meta-hydroxyephedrine ([C]mHED) positron emission tomography (PET) and cardiac magnetic resonance (CMR) imaging 24 h after a 30 min myocardial ischemic injury.

Standardizing tumor measurement on F-FDG PET is crucial for the routine clinical use of powerful PET-derived lymphoma prognostic factors such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG). The recent proposal of an SUV of 4 as a new reference segmentation threshold for most aggressive lymphomas may homogenize volume-based metrics and facilitate their clinical application. This study compared MTV and TLG in primary mediastinal B-cell lymphoma (PMBCL) patients estimated using an SUV of 4 and the current threshold at 25% of SUV Baseline PET metrics were evaluated in 501 PMBCL patients from the IELSG37 trial.

Sea Cucumber Specialist Group, Species Survival Commission, International Union for Conservation of Nature, Gland, Switzerland.

Sea cucumbers paradoxically suffer from being both highly prized and commonly disregarded. As an Asian medicine and delicacy, they command fabulous prices and are thus overfished, poached, and trafficked. As noncharismatic animals, many are understudied and inadequately protected.

The incidence of brain metastases (BrM) in patients with metastatic melanoma is reported to be 30-50% and constitutes the third most frequent BrM after breast and renal cancers. Treatment strategies including surgical resection, stereotactic radiation, and immunotherapy have improved clinical response rates and overall survival, but the changes that occur in circulating melanoma cells to promote invasion of the brain are not fully understood. To investigate brain tropism, we generated new variants of the B16 mouse melanoma model by serially passaging B16 cells through the brain of immune competent syngeneic C57BL/6 mice.
