Article Synopsis
  • The CABASTY study investigated the effects of biweekly administration of a lower dose of cabazitaxel on pain and quality of life for older men with metastatic castration-resistant prostate cancer (mCRPC).
  • In a trial involving 196 patients, researchers compared biweekly dosing (16 mg/m) to a standard triweekly dosing (25 mg/m) regarding pain progression and health-related quality of life (HRQoL).
  • Results showed no significant differences in pain progression or HRQoL between treatment groups, but the biweekly group experienced a delayed onset of some adverse events, suggesting it could be a safer option for older patients.

Background: This randomized controlled trial examined the feasibility of adding eccentric exercise to a conventional cardiac rehabilitation program (CCRP) for coronary heart disease patients.

Methods: Ninety-three patients were randomly assigned to either the MIX group (eccentric ergometer + CCRP) or the CON group (concentric ergometer + CCRP) for 7 weeks. Training effectiveness was assessed based on "good responders" showing improved functional capacities, such as 6-minute walk test (6MWT) distance and maximal voluntary contraction of the plantar flexors (ankle MVC).

Despite the efforts towards malaria eradication, latest estimates show that the number of malaria cases is still rising, and malaria continues to have a devastating impact on people's health and livelihoods particularly in populations located in sub-Saharan Africa . As a Product Development Partnership (PDP), MMV Medicines for Malaria Venture (MMV) plays a crucial role by using public and philanthropic funds to engage the pharmaceutical industry and academic research institutions to discover, develop and deliver the new drugs needed to control and eradicate malaria. MMV Discovery, working with partners, has developed a robust pipeline of molecules and a reliable discovery engine able to support research projects from screening to candidate nomination, providing access to centers of expertise and evaluating the profile and potential of molecules.

Efforts to tackle malaria must continue for a disease that threatens half of the global population. Parasite resistance to current therapies requires new chemotypes that are able to demonstrate effectiveness and safety. Previously, we developed a machine-learning-based approach to predict compound antimalarial activity, which was trained on the compound collections of several organizations.

Importance: Many patients 65 years or older with metastatic castration-resistant prostate cancer (mCRPC) are denied taxane chemotherapy because this treatment is considered unsuitable.

Objective: To determine whether biweekly cabazitaxel (CBZ), 16 mg/m2 (biweekly CBZ16), plus prophylactic granulocyte colony-stimulating factor (G-CSF) at each cycle reduces the risk of grade 3 or higher neutropenia and/or neutropenic complications (eg, febrile neutropenia, neutropenic infection, or sepsis) compared with triweekly CBZ, 25 mg/m2 (triweekly CBZ25), plus G-CSF (standard regimen).

Design, Setting, And Participants: A total of 196 patients 65 years or older with progressive mCRPC were enrolled in this prospective phase 3 randomized clinical trial conducted in France (18 centers) and Germany (7 centers) between May 5, 2017, and January 7, 2021.

The origin of high-energy cosmic rays, atomic nuclei that continuously impact Earth's atmosphere, is unknown. Because of deflection by interstellar magnetic fields, cosmic rays produced within the Milky Way arrive at Earth from random directions. However, cosmic rays interact with matter near their sources and during propagation, which produces high-energy neutrinos.

With artemisinin-resistant parasites emerging in Africa, the need for new antimalarial chemotypes is persistently high. The ideal pharmacodynamic parameters of a candidate drug are a rapid onset of action and a fast rate of parasite killing or clearance. To determine these parameters, it is essential to discriminate viable from nonviable parasites, which is complicated by the fact that viable parasites can be metabolically inactive, whilst dying parasites can still be metabolically active and morphologically unaffected.

Article Synopsis
  • A supermassive black hole in the galaxy NGC 1068, hidden by cosmic dust, is believed to power its active core, and neutrinos might help us understand this.
  • Researchers analyzed data from the IceCube neutrino detector from 2011 to 2020 to detect neutrinos from various gamma-ray sources, including NGC 1068.
  • They discovered an excess of high-energy neutrinos from NGC 1068, indicating a significant connection to the galaxy's activity, and these neutrinos were found to be much more abundant than previously measured gamma rays from the same source.

  • The study investigates the presence of an unstable sterile neutrino using eight years of atmospheric muon neutrino data collected at the IceCube Neutrino Observatory.
  • Results indicate that both traditional three-neutrino models and 3+1 sterile neutrino models are less favored compared to the unstable sterile neutrino model, but no significant evidence for 3+1 neutrinos with decay was found.
  • The research provides specific parameters for the unstable sterile neutrino model, while also excluding favored regions of the 3+1 model from prior short-baseline oscillation studies.

We report a search for nonstandard neutrino interactions (NSI) using eight years of TeV-scale atmospheric muon neutrino data from the IceCube Neutrino Observatory. By reconstructing incident energies and zenith angles for atmospheric neutrino events, this analysis presents unified confidence intervals for the NSI parameter ε_{μτ}. The best-fit value is consistent with no NSI at a p value of 25.

The current Covid-19 pandemic has underlined the need for a more coordinated and forward-looking investment in the search for new medicines targeting emerging health care threats. Repositioning currently approved drugs is a popular approach to any new emerging disease, but it represents a first wave of response. Behind this would be a second wave of more specifically designed therapies based on activities against specific molecular targets or in phenotypic assays.

We report on the first measurement of the astrophysical neutrino flux using particle showers (cascades) in IceCube data from 2010-2015. Assuming standard oscillations, the astrophysical neutrinos in this dedicated cascade sample are dominated (∼90%) by electron and tau flavors. The flux, observed in the sensitive energy range from 16 TeV to 2.

We report the observation of radar echoes from the ionization trails of high-energy particle cascades. Data were taken at the SLAC National Accelerator Laboratory, where the full electron beam (∼10^{9}  e^{-} at ∼10  GeV/e^{-}) was directed into a plastic target to simulate an ultrahigh-energy neutrino interaction. The target was interrogated with radio waves, and coherent radio reflections from the cascades were detected with properties consistent with theoretical expectations.

This Letter presents the results from pointlike neutrino source searches using ten years of IceCube data collected between April 6, 2008 and July 10, 2018. We evaluate the significance of an astrophysical signal from a pointlike source looking for an excess of clustered neutrino events with energies typically above ∼1  TeV among the background of atmospheric muons and neutrinos. We perform a full-sky scan, a search within a selected source catalog, a catalog population study, and three stacked Galactic catalog searches.
