Modern advances in systemic and localized therapies for patients with renal cell carcinoma (RCC) have significantly improved patients' outcomes. If disease progression occurs after initial treatment, clinicians often have multiple options for a first salvage therapy. Because salvage and initial treatments both may affect overall survival time, and they may interact in unanticipated ways, there is a growing need to determine sequences of initial therapy and first salvage therapy that maximize overall survival while maintaining quality of life.

Background: Addiction medicine providers have a key role in HIV prevention amidst rising HIV incidence in persons who inject drugs (PWID). Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are vastly underutilized in this population. Inpatient hospitalization represents a potential touchpoint for initiation of HIV prophylaxis, though little research explores the role of addiction providers.

Background: Plasma biomarker assays provide an opportunity to reassess whether Alzheimer's disease, Parkinson's disease dementia (PDD), and dementia with Lewy bodies (DLB) plasma biomarkers are diagnostically useful.

Objective: We hypothesized that immunomagnetic reduction (IMR) of plasma biomarkers could differentiate between patients with PDD and DLB and healthy patients when combined with established clinical testing measures.

Methods: Plasma samples from 61 participants (12 PDD, 12 DLB, 37 controls) were analyzed using IMR to quantify amyloid-β 42 (Aβ), total tau (t-tau), phosphorylated tau at threonine 181 (p-tau181), and α-synuclein (α-syn).

Article Synopsis
  • Disorders of consciousness (DoC) refer to conditions where a person has reduced awareness or ability to respond, and deep brain stimulation (DBS) is being explored as a treatment, with varying effectiveness based on patient specifics and stimulation methods.
  • In a study of 40 DoC patients receiving DBS, improved consciousness was linked to better gray matter preservation, particularly in the striatum, and effective stimulation targeted specific brain areas, particularly the thalamic centromedian-parafascicular complex.
  • The research highlights the need for precise electrode placement and suggests a connection between successful DBS treatment for DoC and mechanisms involved in other conditions that impair consciousness, such as absence seizures and brain lesions

Background: Delayed and missed diagnosis are a persistent barrier to tuberculosis control, partly driven by limitations associated with sputum collection and an unmet need for decentralized testing. Household contact investigation with point-of-care testing of non-invasive specimens like tongue swabs are hitherto undescribed and may be a cost-effective solution to enable community-based active case finding.

Methods: In-home, molecular point-of-care testing was conducted using sputum and tongue specimens collected from all household contacts of confirmed tuberculosis cases.

Loss of proteostasis is well documented during physiological aging and depends on the progressive decline in the activity of two major degradative mechanisms: the ubiquitin-proteasome system (UPS) and the autophagy-lysosomal pathway. This decline in proteostasis is exacerbated in age-associated neurodegenerative diseases, such as Parkinson's Disease (PD). In PD, patients develop an accumulation of aggregated proteins and dysfunctional mitochondria, which leads to ROS production, neuroinflammation and neurodegeneration.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.

Article Synopsis
  • - The ATLAS experiment at the LHC conducted a search for long-lived particles (LLPs) using a large dataset (140 fb^{-1}) from proton-proton collisions at 13 TeV, focusing on LLPs with masses from 5 to 55 GeV that decay within the inner detector.
  • - The study considered scenarios where LLPs are produced from exotic Higgs boson decays and models involving axionlike particles (ALPs).
  • - No significant findings above expected background levels were detected, leading to the establishment of upper limits on various production rates involving the Higgs boson and the top quark related to LLPs and ALPs.

Measurement of α-synuclein as protein cargo in plasma extracellular vesicles.

Proc Natl Acad Sci U S A

November 2024

Wyss Institute for Biologically Inspired Engineering, Harvard University, Boston, MA 02115.

Extracellular vesicles (EVs) are released by all cells and hold great promise as a class of biomarkers. This promise has led to increased interest in measuring EV proteins from both total EVs as well as brain-derived EVs in plasma. However, measuring cargo proteins in EVs has been challenging because EVs are present at low levels, and EV isolation methods are imperfect at separating EVs from free proteins.

Antiretroviral treatment (ART) initiation during the early stages of HIV-1 infection is associated with a higher probability of maintaining drug-free viral control during subsequent treatment interruptions, for reasons that remain unclear. Using samples from a randomized-controlled human clinical trial evaluating therapeutic HIV-1 vaccines, we here show that early ART commencement is frequently associated with accelerated and efficient selection of genome-intact HIV-1 proviruses in repressive chromatin locations during the first year after treatment initiation. This selection process was unaffected by vaccine-induced HIV-1-specific T cell responses.

  • About one-third of US adults have tattoos, raising concerns about potential long-term health risks, including exposure to carcinogens and immune responses.
  • A case-control study comparing 820 individuals with hematologic cancers to 8200 controls found no overall strong link between tattoos and major blood cancers but revealed some associations in younger adults (ages 20-60) for rarer types of non-Hodgkin lymphoma and certain myeloid neoplasms.
  • While the results were not definitive, they suggest a possible increased risk of specific hematologic cancers tied to tattooing, indicating a need for further research, especially given the high tattoo prevalence in younger adults.
