Background: Lecanemab, a novel humanized immunoglobulin G1 monoclonal antibody targeting both neurotoxic Aβ protofibrils and Aβ plaques, has demonstrated the ability to substantially reduce markers of amyloid and significantly slow clinical decline on multiple measures of cognition and function in early AD in phase 2 (Study 201) and phase 3 (Clarity AD) studies. In these clinical studies, several plasma biomarkers assessments (Aβ42/40 ratio, p-tau181, GFAP, and p-tau217) showed improvements comparing lecanemab with placebo. Herein, we utilized modelling and simulations to evaluate the long-term effects of lecanemab on biomarkers of neurodegeneration in plasma.

Aim: Lebrikizumab is an interleukin (IL)-13 inhibitor that specifically blocks IL-13 signaling. Here, we report the effects of lebrikizumab on asthma serum biomarkers in 2 phase 3 clinical studies.
Methods: LAVOLTA I and LAVOLTA II are replicate, double-blind, placebo-controlled trials with 52-week placebo-controlled treatment periods that evaluated lebrikizumab 37.

To summarise the clinical characteristics, radiological features, treatments and prognosis of patients with myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) overlapped with NMDA receptor (NMDAR) encephalitis. We retrospectively analysed patients who exhibited dual positivity for MOG antibodies and NMDAR antibodies in serum/CSF from Jan 2018 to Jun 2023. Ten patients with MOGAD and NMDAR encephalitis were enrolled.

Migratory water birds are considered to be carriers of high pathogenicity avian influenza viruses (HPAIVs). In Japan, mallards are often observed during winter, and HPAIV-infected mallards often shed viruses asymptomatically. In this study, we focused on mallards as potential carriers of HPAIVs and investigated whether individual wild mallards are repeatedly infected with HPAIVs and act as HPAIV carriers multiple times within a season.

Background: Chronic pulmonary aspergillosis (CPA) is a disease commonly caused by Aspergillus fumigatus and other Aspergillus species characterized by cavitary lung lesions. Tea garden population is an agrarian population of Assam, mostly associated with tea plantations. Assam is a major tea-producing state with 803 tea gardens producing approximately 50% of the total tea in India, of which 177 are present in the Dibrugarh district alone.
