Use of immunoglobulin replacement therapy in patients with secondary antibody deficiency in daily practice: a European expert Q&A-based review.

Introduction: Secondary antibody deficiencies (SAD) are often a side effect of specific therapies that target B cells directly or affect the antibody response indirectly. Treatment of immunodeficiency by immunoglobulin replacement therapy (IgRT) is well established in primary antibody deficiencies, although the evidence for its use in SAD is less well established. To fill the gap and provide opinion and advice for daily practice, a group of experts met to discuss current issues and share best practical experience.

Assessment of a quadrivalent nucleoside-modified mRNA vaccine that protects against group 2 influenza viruses.

Combined vaccine formulations targeting not only hemagglutinin but also other influenza virus antigens could form the basis for a universal influenza virus vaccine that has the potential to elicit long-lasting, broadly cross-reactive immune responses. Lipid nanoparticle (LNP)-encapsulated messenger RNA (mRNA) vaccines can be utilized to efficiently target multiple antigens with a single vaccine. Here, we assessed the immunogenicity and protective efficacy of nucleoside-modified mRNA-LNP vaccines that contain four influenza A group 2 virus antigens (hemagglutinin stalk, neuraminidase, matrix protein 2, and nucleoprotein) in mice.

Detection of Velogenic Avian Paramyxoviruses in Rock Doves in New York City, New York.

Avian paramyxovirus 1 (APMV-1), also known as Newcastle disease virus (NDV), causes severe and economically important disease in poultry around the globe. Although a limited amount of APMV-1 strains in urban areas have been characterized, the role of the urban wild bird population as an APMV-1 reservoir is unclear. Because urban birds may have an important role for long-term circulation of the virus, fecal and swab samples were collected by community scientists from wild birds in New York City (NYC), New York, United States.

Knowledge, attitudes and practices related to schistosomiasis transmission and control in Leyte, Philippines.

Schistosomiasis is a chronic but preventable disease that affects 260 million people worldwide. In the Philippines, 860,000 people are afflicted with Schistosoma japonicum annually, and another 6.7 million live in endemic areas.

In-situ laser synthesis of Nd-Al-O coatings: the role of sublattice cations in eutectic formation.

Neodymium aluminate coatings have been prepared in-situ by the laser zone melting (LZM) method, using a CO2 SLAB-type laser emitting at 10.6 µm. Polycrystalline Al2O3 commercial plates have been used as substrates, and coatings were prepared from the corresponding mixtures of powdered neodymium and aluminium oxides as starting materials.
