Extremely high-Q microresonators provide an attractive platform for a plethora of photonic applications including optical frequency combs, high-precision metrology, telecommunication, microwave generation, narrow linewidth lasers, and stable frequency references. Moreover, the desire for compactness and a low power threshold for nonlinear phenomena have spurred investigation into integrated and scalable solutions. Historically, crystalline microresonators with Q ∼ 10 were one of the first material platforms providing unprecedented optical performance in a small form factor.

  • Current influenza vaccines have limited effectiveness (19%-60%) and existing treatments are ineffective in advanced stages, leading to significant death rates in the U.S. (25,000-72,000/year) and concerns with avian strains infecting humans.
  • Researchers developed zanDR, a bispecific small molecule that inhibits the virus's neuraminidase and recruits anti-rhamnose and anti-DNP antibodies, effectively mimicking the functions of both antiviral treatments and vaccines.
  • Studies show that zanDR provides 100% protection in severely infected mice with a single dose, reducing viral loads much more effectively than current therapies, while also lowering inflammation and protecting lung tissue, suggesting a promising combined immunotherapy and chemotherapy approach.

Inflammatory syndromes, including those caused by infection, are a major cause of hospital admissions among children and are often misdiagnosed because of a lack of advanced molecular diagnostic tools. In this study, we explored the utility of circulating cell-free RNA (cfRNA) in plasma as an analyte for the differential diagnosis and characterization of pediatric inflammatory syndromes. We profiled cfRNA in 370 plasma samples from pediatric patients with a range of inflammatory conditions, including Kawasaki disease (KD), multisystem inflammatory syndrome in children (MIS-C), viral infections, and bacterial infections.

Background: The benefit of intravenous thrombolysis with alteplase before endovascular thrombectomy (EVT) for acute ischemic stroke due to large vessel occlusion remains debated. In this study, we analyzed the cost-effectiveness of EVT alone versus intravenous alteplase before EVT in patients directly admitted to EVT-capable stroke centers from the Dutch health care payer perspective.

Methods: A decision analysis was performed using a Markov model with 15-year simulated follow-up to estimate total costs, quality-adjusted life years, and an incremental cost-effectiveness ratio of intravenous alteplase before EVT compared with EVT alone.

  • * Data from 670 patients revealed that while IVT may improve some outcomes, such as higher chances of achieving a modified Rankin Scale score of 0-2 in univariable analysis, this benefit was not consistently observed in more rigorous multivariable analyses.
  • * Overall, the findings suggest that adjunctive IVT may not significantly enhance clinical outcomes or safety compared to MT alone for this patient population.

  • Plasmodium falciparum's RH5 protein is a promising candidate for a malaria vaccine, and understanding the antibody response during natural infections is crucial for optimizing vaccine efficacy.
  • Researchers found that B cells reacting to RH5 were uncommon, and the IgG responses in malaria-exposed individuals were short-lived despite multiple infections.
  • Some antibodies from malaria-exposed individuals showed strong neutralizing ability and targeted similar sites as the most effective vaccine-induced antibodies, indicating that natural infections might enhance the effectiveness of RH5 vaccines in the future.

Introduction: Non-communicable diseases (NCDs) have surpassed infectious diseases as the leading global cause of death, with the Southeast Asian region experiencing a significant rise in NCD prevalence over the past decades. Despite the escalating burden, screening for NCDs remains at very low levels, resulting in undetected cases, premature mortality and high public healthcare costs. We investigate whether community-based NCD prevention and management programmes are an effective solution.

  • The study investigates the effectiveness of endovascular treatment (EVT) versus medical management (MM) in patients with isolated posterior cerebral artery occlusion (iPCAO) during acute ischemic strokes, lacking prior randomized trial evidence.
  • Results show that EVT leads to better functional outcomes for patients with more severe stroke symptoms (NIHSS >6), but not for those with milder symptoms (NIHSS ≤6).
  • Additionally, while EVT improves outcomes, it is also linked to a higher occurrence of symptomatic intracranial hemorrhages, regardless of initial stroke severity.

Fibrolamellar carcinoma (FLC) is a liver tumor with a high mortality burden and few treatment options. A promising therapeutic vulnerability in FLC is its driver mutation, a conserved DNAJB1-PRKACA gene fusion that could be an ideal target neoantigen for immunotherapy. In this study, we aim to define endogenous CD8 T cell responses to this fusion in FLC patients and evaluate fusion-specific T cell receptors (TCRs) for use in cellular immunotherapies.
