The main aim of this research is to identify the transmitted resistance (RT) of the Human Immunodeficiency Virus (HIV) in subjects from nine cities of Peru. For this, a descriptive and cross-sectional study was carried out in 135 adult subjects who agreed to participate through an informed consent. Blood samples were collected to perform the CD4 / CD8 cell count, viral load and HIV Genotyping. Socio-epidemiological information was collected from the participants through surveys. The results revealed a RT frequency of 9.8% (13/132). The information from this research might help improve the intervention and monitoring programs for antiretroviral resistance in the country.

Taylorella equigenitalis is the causative agent of sexually transmitted contagious equine metritis. Infections manifest as cervicitis, vaginitis and endometritis and cause temporary infertility and miscarriages of mares. While previous studies have analyzed this organism for various parameters, the evolutionary dynamics of this pathogen, including the emergence of antibiotic resistance, remains unresolved.

Background: Neurofibrillary tangles formed by hyperphosphorylated tau aggregates in the brain are one of the classical hallmarks of Alzheimer's Disease (AD). Tau aggregates have been shown to elicit cytotoxicity, leading to overall neuronal loss and cognitive decline in AD. These aggregates can be transmitted from neurons and glial cells to other brain cells through a process known as tau spreading, and ultimately reach the endothelial cells (ECs) lining the vessel walls, thus, causing dysfunction of the neurovascular unit (NVU), a complex multicellular system surrounding brain vessels.

Malaria, transmitted by mosquitoes infected with Plasmodium parasites, remains a significant health issue with global travel increasing the risk of imported malaria. This study investigates imported malaria cases in the Republic of Korea from 2009 to 2018 using data from the Korea National Infectious Disease Surveillance System. During this period, 601 imported cases were reported, with 82.

Data on the HIV care cascade demonstrated challenges in achieving Ending the HIV Epidemic (EHE) targets across all 18 EHE focus metropolitan areas, but innovative adherence interventions using point-of-care tenofovir testing and motivational interviewing support care cascade outcomes in Namibia and South Africa, respectively. Data on treatment with long-acting injectable (LAI) antiretroviral therapy (ART) demonstrated high acceptability, retention, and virologic suppression including in groups that were not well represented in clinical trials including persons born female and persons with detectable viral loads. The adjuvanted hepatitis B vaccine appeared to be safe and appeared to be superior to conventional hepatitis B vaccines in persons with HIV (PWH) who were prior nonresponders to the hepatitis B vaccine.

Article Synopsis
- Ticks are major ectoparasites that spread serious diseases like Lyme disease and Rocky Mountain spotted fever, posing challenges for public health and livestock due to emerging resistance to acaricides.
- The review discusses how genetic mutations, metabolic processes, and behavior contribute to this resistance, while also highlighting the economic impact estimated at $20 billion in livestock loss annually.
- It emphasizes the need for new acaricides, innovative control strategies, and regular monitoring to effectively manage tick populations and protect public health and livestock productivity.
