Intratumoral Injection of mRNA-2752 and Pembrolizumab for High-Risk Ductal Carcinoma In Situ: A Phase 1 Nonrandomized Clinical Trial.

Importance: Intratumoral immunotherapy that leverages the biological characteristics of high-risk ductal carcinoma in situ (DCIS) may be able to reduce the extent of surgical treatment and provide an alternative approach to improve patient outcomes.

Objective: To determine if combination intratumoral immunotherapy can activate immune cells to shrink or eliminate high-risk DCIS.

Design, Setting, And Participants: This phase 1 open-label nonrandomized clinical trial at a single academic center tested the safety and efficacy of intratumoral immunotherapy in patients with high-risk DCIS, defined as at least 2 of the following present: younger than 45 years, tumor size greater than 5 cm, high-grade, palpable mass, hormone receptor (HR)-negative, or ERBB2-positive.

Hemophagocytic Lymphohistiocytosis (HLH) Following Immune Checkpoint Therapy (ICT).

In the past decade, the use of immune checkpoint therapy (ICT) has increased across many malignancies, including metastatic renal cell carcinoma as an option for frontline and subsequent lines of therapy. Despite the many therapeutic benefits of ICT, its use is complicated by the potential risk of immune-related adverse events (irAEs). One rare but potentially life-threatening irAE is hemophagocytic lymphohistiocytosis (HLH).

AEDES JAPONICUS: A TENANT INVADER IN THE GREAT SMOKY MOUNTAINS NATIONAL PARK, USA1.

Invasive organisms may cause ecologic, economic, and public health harm. Aedes japonicus is an invasive mosquito species of known ecologic and public health importance that has widely spread throughout the eastern USA since initially being recognized in Connecticut in 1998. Here, we report the known distributions of Ae.

Six-Month Outcomes in the Long-Term Outcomes After the Multisystem Inflammatory Syndrome in Children Study.

Importance: Multisystem inflammatory syndrome in children (MIS-C) is a life-threatening complication of COVID-19 infection. Data on midterm outcomes are limited.

Objective: To characterize the frequency and time course of cardiac dysfunction (left ventricular ejection fraction [LVEF] <55%), coronary artery aneurysms (z score ≥2.
