A giant planet transiting a 3-Myr protostar with a misaligned disk.

Nature

November 2024

Department of Physics and Kavli Institute for Astrophysics and Space Research, Massachusetts Institute of Technology, Cambridge, MA, USA.

Astronomers have found more than a dozen planets transiting stars that are 10-40 million years old, but younger transiting planets have remained elusive. The lack of such discoveries may be because planets have not fully formed at this age or because our view is blocked by the protoplanetary disk. However, we now know that many outer disks are warped or broken; provided the inner disk is depleted, transiting planets may thus be visible.

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal neoplasm that can locally recur and potentially metastasize. Approximately 50% of IMTs harbor rearrangements in the gene encoding anaplastic lymphoma kinase (ALK), a receptor tyrosine kinase that can be therapeutically targeted with tyrosine kinase inhibitors (TKIs). With successful application of TKI in ALK-positive nonsmall cell carcinoma (NSCLC), ALK inhibitors are often first-line treatments for patients with unresectable or metastatic IMTs.

Aims: Beta-blockers may inhibit neprilysin activity and conversely, neprilysin inhibition may have a sympatho-inhibitory action. Consequently, sacubitril/valsartan may have a greater effect in patients not receiving a beta-blocker compared to those treated with a beta-blocker.

Methods And Results: We examined the effect of sacubitril/valsartan compared to enalapril on outcomes according to background beta-blocker treatment in the 8399 patients with heart failure with reduced ejection fraction enrolled in PARADIGM-HF.

Background: In BRAF-mutated high-risk melanoma, targeted therapy (BRAF/MEK inhibitors) and checkpoint inhibitor (CPI) immunotherapy have durable benefits as first-line (1L) adjuvant therapy. Based on differing action mechanisms of BRAF/MEK inhibitors and CPI immunotherapies, there is interest in evaluating the activity of 2L adjuvant targeted therapy in decreasing the risk of subsequent recurrence after repeat resection following relapse on/after 1L adjuvant CPI.

Patients And Methods: This was a retrospective review of BRAF V600-mutated resected stage III/IV melanoma patients in the United States, Australia, and The Netherlands who received 1L adjuvant CPI immunotherapy, relapsed locoregionally/distantly, were again resected to no evidence of disease, and received dabrafenib/trametinib (dab/tram) as 2L adjuvant therapy.

Similarity in feature space dictates the efficiency of attentional selection during ensemble processing.

Psychon Bull Rev

November 2024

Department of Psychological and Brain Sciences, Dartmouth College, Hanover, NH, USA.

Humans can rapidly and accurately extract statistical information about features of the visual environment, an ability referred to as ensemble perception. However, little is known about how ensemble estimates are affected when task-irrelevant and distracting feature information is present. Here, we tested how effectively feature-based attention-when tuned to a specific color-can select a single item set out of two intermixed ensembles of colored lines.

Significance: Fluorescence sensing within tissue is an effective tool for tissue characterization; however, the modality and geometry of the image acquisition can alter the observed signal.

Aim: We introduce a novel optical fiber-based system capable of measuring two fluorescent contrast agents through 2 cm of tissue with simple passive electronic switching between the excitation light, simultaneously acquiring fluorescence and excitation data. The goal was to quantify indocyanine green (ICG) and protoporphyrin IX (PpIX) within tissue, and the sampling method was compared with wide-field surface imaging to contrast the value of deep sensing versus surface imaging.

Background: As the opioid epidemic continues to have a major negative impact across the US, community pharmacies have come under scrutiny from legal systems attempting to hold them accountable for their role in over dispensing and lack of patient intervention. While the most available tool for monitoring patients' opioid use is Prescription Drug Monitoring Programs (PDMP), these do not provide pharmacists with actionable information and decision support. Our study addresses this gap through three objectives: [1] incorporate validated opioid risk metric thresholds into a PDMP platform to create the Opioid Risk Reduction Clinical Decision Support (ORRCDS) tool; [2] assess ORRCDS' ability to reduce patient opioid risk; [3] assess ORRCDS' sustainability and viability for broader dissemination in community pharmacy.

Objective: The objective of this study was to report 52-week safety and efficacy of ianalumab from phase 2b dose-finding study in patients with Sjögren's disease (SjD).

Methods: Patients randomly received (1:1:1:1) ianalumab (5, 50, or 300 mg) or placebo subcutaneously every 4 weeks until week 24 (treatment period [TP]1). At week 24, patients on 300 mg were rerandomized to continue 300 mg or receive placebo until week 52 (TP2), patients on placebo were switched to ianalumab 150 mg, and patients on 5 and 50 mg directly entered posttreatment safety follow-up.

A prediction model to assess the risk of hospital readmission can be valuable to identify patients who may benefit from extra care. Developing hospital-specific readmission risk prediction models using local data is not feasible for many institutions. Models developed on data from one hospital may not generalize well to another hospital.

Department of Molecular Biosciences and LaMontagne Center for Infectious Diseases, The University of Texas at Austin, Austin, Texas, USA.

Intestinal colonization and virulence factor production in response to environmental cues is mediated through several regulatory factors in , including the highly conserved RNA-binding global regulatory protein CsrA. We have shown previously that CsrA increases synthesis of the virulence-associated transcription factor ToxR in response to specific amino acids (NRES) and is required for the virulence of in the infant mouse model of cholera. In this study, we mapped the 5' untranslated region (5' UTR) of and showed that CsrA can bind directly to an RNA sequence encompassing the 5' UTR, indicating that the regulation of ToxR levels by CsrA is direct.

Achieving equitable health in epilepsy requires addressing systemic barriers and social determinants of health to ensure that every person with epilepsy has the opportunity to attain their highest level of health. We review the literature on disparities that affect several minoritized groups living with epilepsy. Early solutions with the potential for modeling towards replication for low socioeconomic status population, non-English language preference communities, sexual and gender minorities, and rural and underserved communities with high social determinants of health burden are shared as examples to catalyze stakeholder investment in identifying and addressing health disparities across the spectrum of epilepsy at both the provider and health systems level.

Aberrant Ras homologous (Rho) GTPase signalling is a major driver of cancer metastasis, and GTPase-activating proteins (GAPs), the negative regulators of RhoGTPases, are considered promising targets for suppressing metastasis, yet drug discovery efforts have remained elusive. Here, we report the identification and characterization of adhibin, a synthetic allosteric inhibitor of RhoGAP class-IX myosins that abrogates ATPase and motor function, suppressing RhoGTPase-mediated modes of cancer cell metastasis. In human and murine adenocarcinoma and melanoma cell models, including three-dimensional spheroid cultures, we reveal anti-migratory and anti-adhesive properties of adhibin that originate from local disturbances in RhoA/ROCK-regulated signalling, affecting actin-dynamics and actomyosin-based cell-contractility.

  • The study examined the relationship between Time in Range (TIR) and Time in Tight Range (TTR) with HbA1c levels in youth and young adults with type 1 diabetes using data from a large diabetes registry.
  • Results showed a strong correlation between TIR and TTR (r = 0.965) and between both metrics and HbA1c levels, indicating that higher TIR and TTR are associated with lower HbA1c levels.
  • Moreover, regression analysis suggested that TIR might be a slightly better predictor of HbA1c compared to TTR, especially in individuals with high blood glucose variability.
