Effective targeting of somatic cancer mutations to enhance the efficacy of cancer immunotherapy requires an individualized approach. Autogene cevumeran is a uridine messenger RNA lipoplex-based individualized neoantigen-specific immunotherapy designed from tumor-specific somatic mutation data obtained from tumor tissue of each individual patient to stimulate T cell responses against up to 20 neoantigens. This ongoing phase 1 study evaluated autogene cevumeran as monotherapy (n = 30) and in combination with atezolizumab (n = 183) in pretreated patients with advanced solid tumors.

Article Synopsis
  • Plasmodium ovale curtisi (Poc) and Plasmodium ovale wallikeri (Pow) are two distinct malaria parasites now recognized in Africa and Asia, previously thought to be one species.
  • A genomic study analyzed 25 newly sequenced isolates from Central and East Africa, finding that genetic variations are geographically clustered and predominantly monoclonal.
  • Poc exhibits higher genetic diversity than Pow, and both species show evidence of selective pressure on certain genes, indicating their adaptation and resilience despite malaria control efforts.

Background Tumor fraction (TF) at liquid biopsy is a potential noninvasive marker for tumor burden, but validation is needed. Purpose To evaluate TF as a potential surrogate for tumor burden, assessed at contrast-enhanced CT across diverse metastatic cancers. Methods This retrospective monocentric study included patients with cancer and metastatic disease, with TF results and contemporaneous contrast-enhanced CT performed between January 2021 and January 2023.

Background: Acquired hemophilia A (AHA) is a rare and severe bleeding disorder characterized by autoantibodies inhibiting coagulation factor (F)VIII. Current treatment of AHA involves bypassing agents or FVIII replacement therapy, yet their efficacy is limited in cases of high inhibitor titers. Emicizumab, a humanized bispecific monoclonal antibody, has shown promising hemostatic effectiveness in persons with congenital hemophilia A (HA) and AHA, but a minority of patients developed anti-drug antibodies (ADAs), compromising its efficacy.

Article Synopsis
  • * Researchers sequenced the genomes of 25 isolates from Central and East Africa, revealing that these isolates are mostly monoclonal and show genetic patterns that correlate with geographical locations.
  • * Results indicated that one species has lower genetic diversity than the other, and both exhibit signs of selective pressures on specific genes, suggesting that their evolutionary paths and responses to control measures in malaria have unique aspects based on their history.

Article Synopsis
  • Angiogenesis involves the sprouting of endothelial cells, and in vitro modeling can be enhanced using biomaterials to encourage their migration.
  • A study was conducted using a fibrin scaffold to observe how HULEC cell line spheroids migrate when embedded, focusing on factors like fibrinogen and thrombin concentrations that affect the gel's properties.
  • Results show that higher thrombin concentrations reduce gel rigidity and promote greater cell migration, providing insights into optimizing fibrin gel conditions for studying angiogenic processes.

Hypothalamic obesity (HO) is defined as abnormal weight gain resulting in severe persistent obesity due to physical, tumor- and/or treatment-related damage to the hypothalamus. HO epidemiology is poorly understood. We developed a database algorithm supporting the standardized identification of tumor/treatment-related HO (TTR-HO) patients.

Background And Purpose: Functional recovery after stroke is often limited, despite various treatment methods such as robot-assisted therapy. Repetitive sensory stimulation (RSS) might be a promising add-on therapy that is thought to directly drive plasticity processes. First positive effects on sensorimotor function have been shown.

In recent years, new targeted therapies have been developed to treat patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer. Some of these therapies have not just become the new therapy standard but also led to significantly longer overall survival rates. The cyclin-dependent kinase 4 and 6 inhibitors (CDK4/6i) have become the therapeutic standard for first-line therapy.

Article Synopsis
  • The IL-22RA1 receptor is important in the pancreas and helps improve insulin secretion from beta-cells while reducing cellular stress.
  • Blocking IL-22RA1 in human pancreatic islets results in lower insulin quality and increased cellular stress, indicating its crucial role in insulin regulation.
  • Experiments in mice lacking IL-22ra1 in beta-cells showed similar negative effects on insulin secretion, increased inflammation, and worsened glucose tolerance, especially in females, highlighting the receptor's significance in metabolic health.

Metabolic dysfunction-associated steatohepatitis (MASH) is the most prevalent cause of liver disease worldwide, with a single approved therapeutic. Previous research has shown that interleukin-22 (IL-22) can suppress β-cell stress, reduce local islet inflammation, restore appropriate insulin production, reverse hyperglycemia, and ameliorate insulin resistance in preclinical models of diabetes. In clinical trials long-acting forms of IL-22 have led to increased proliferation in the skin and intestine, where the IL-22RA1 receptor is highly expressed.

Background: Despite the high incidence of blunt trauma in older adults, there is a lack of evidence-based guidance for computed tomography (CT) imaging in this population. We aimed to identify an algorithm to guide use of a pan-scan (head/cervical spine [C-spine]/torso) or a selective scan (head/C-spine ± torso). We hypothesized that a patient's initial history and examination could be used to guide imaging.

Article Synopsis
  • The study investigates the genetic causes of Lisch epithelial corneal dystrophy (LECD) through a multicenter cohort involving 27 individuals from 17 families.
  • Researchers found nine rare variants of the MCOLN1 gene in 23 patients, indicating that mutations in this gene lead to LECD and potentially other conditions like mucolipidosis IV (MLIV).
  • The findings suggest that while MCOLN1 haploinsufficiency is the main contributor to LECD, there is variability in how strongly the condition manifests, highlighting a complex relationship between genetics and disease expression.

Studies have shown that colorectal cancer prognosis can be predicted by deep learning-based analysis of histological tissue sections of the primary tumor. So far, this has been achieved using a binary prediction. Survival curves might contain more detailed information and thus enable a more fine-grained risk prediction.

Background: The locus was genome-wide significantly associated with coronary artery disease. Lack of the ECM (extracellular matrix) protease ADAMTS-7 (A disintegrin and metalloproteinase-7) was shown to reduce atherosclerotic plaque formation. Here, we sought to identify molecular mechanisms and downstream targets of ADAMTS-7 mediating the risk of atherosclerosis.

Hyperpolarization techniques increase nuclear spin polarization by more than four orders of magnitude, enabling metabolic MRI. Even though hyperpolarization has shown clear value in clinical studies, the complexity, cost and slowness of current equipment limits its widespread use. Here, a polarization procedure of [1- C]pyruvate based on parahydrogen-induced polarization by side-arm hydrogenation (PHIP-SAH) in an automated polarizer is demonstrated.

Background And Purpose: Lateropulsion (LP) is a profound disorder of postural control that has a significant impact on neurorehabilitation. Knowledge of relevant brain areas could guide decisions on appropriate intervention methods. Although LP severity and duration are highly variable in individuals with LP, imaging studies on LP have not sufficiently considered these aspects.

Article Synopsis
  • This study investigates the effectiveness of large hemicraniectomy (over 14 cm) vs. standard hemicraniectomy (14 cm or less) in treating malignant cerebral infarction to see if larger surgeries result in better outcomes or lower mortality rates.
  • The research analyzed data from the DESTINY registry, focusing on long-term functional outcomes and complications in a group of 130 patients.
  • The findings indicate that there were no significant differences in outcomes or complications between the two sizes of surgery, suggesting that larger hemicraniectomy may not offer additional benefits.
