With advances in global health care, ageing populations are expected to grow worldwide throughout the 21 century. Increased lifespan is a testament to modern medical and social practices, but also presents a growing challenge to a system with limited resources. Elderly populations present specific concerns related to preventative health practices, especially vaccination. Although the power of vaccination is unquestionable in controlling infectious disease, immunosenescence can lead to reduced immune responses following immunization in the elderly, and increased morbidity and mortality. Further complicating this issue, some vaccines themselves may pose a substantial safety risk in the elderly when compared to younger counterparts. Though any health care intervention must balance risk and reward, safety and immunogenicity are often poorly characterized in older populations. This review explores several domestic and travel vaccines, examining what is known concerning efficacy and safety in the elderly, and considers future alternatives.

In the EU, conditional marketing authorization is a pragmatic tool for early approval of a medicine that fulfills an unmet medical need. In the pharmaceutical legislation, an unmet medical need means that a condition lacks a satisfactory method for diagnosis, prevention, or treatment. If such satisfactory methods exist, the new medicinal product must hold a major therapeutic advantage for those affected, meaning that it must demonstrate an improvement in efficacy or safety over existing methods or, in exceptional cases, a major improvement in patient care.

Typical Atrial Flutter: A Practical Review.

J Cardiovasc Electrophysiol

January 2025

Cardiology Division, Geneva University Hospitals, Geneva, Switzerland.

Typical atrial flutter (AFL), defined as cavotricuspid isthmus (CTI)-dependent macro-re-entrant atrial tachycardia, often causes debilitating symptoms, and is associated with increased incidence of atrial fibrillation, stroke, heart failure, and death. Typical AFL occurs in patients with atrial remodeling and shares risk factors with atrial fibrillation. It is also common in patients with a history of prior heart surgery or catheter ablation.

() commonly induces refractory infection due to its multidrug-resistant nature. To date, there have been no reports on the application of phage treatment for infection. This study was conducted to explore the feasibility of phage application in treating refractory infection by collaborating with a 59-year-old male patient with a pulmonary infection of multidrug-resistant Our experiments included three domains: ) selection of the appropriate phage, ) verification of the efficacy and safety of the selected phage, ) confirmation of phage-bacteria interactions.

Enhanced safety and efficacy profile of CD40 antibody upon encapsulation in pHe-triggered membrane-adhesive nanoliposomes.

Nanomedicine (Lond)

January 2025

Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University, Detroit, MI, USA.

Aim: To develop pH (pHe)-triggered membrane adhesive nanoliposome (pHTANL) of CD40a to enhance anti-tumor activity in pancreatic cancer while reducing systemic toxicity.

Materials And Methods: A small library of nanoliposomes (NL) with various lipid compositions were synthesized to prepare pH (pHe)-triggered membrane adhesive nanoliposome (pHTANL). Physical and functional characterization of pHTANL-CD40a was performed via dynamic light scattering (DLS), Transmission Electron Microscopy (TEM), confocal microscopy, and flow cytometry.
