Assessment of Covid-19 vaccine confidence among healthcare personnel in the safety-net sector in the United States and Puerto Rico.

Background: This study aimed to assess COVID-19 vaccine confidence among healthcare personnel in the safety net sector of the United States and Puerto Rico. This study aimed to examine the extent to which increased knowledge and positive attitudes toward COVID-19 vaccine safety and efficacy were associated with healthcare workers' COVID-19 vaccination status and their recommendation of the vaccine to all patients.

Methods: Online survey data were collected from health care workers working in Free and Charitable Clinics across the United States and Federally Qualified Health Centers in Puerto Rico.

Neutrophilia with damage to the blood-brain barrier and neurovascular unit following acute lung injury.

Background: Links between acute lung injury (ALI), infectious disease, and neurological outcomes have been frequently discussed over the past few years, especially due to the COVID-19 pandemic. Yet, much of the cross-communication between organs, particularly the lung and the brain, has been understudied. Here, we have focused on the role of neutrophils in driving changes to the brain endothelium with ensuing microglial activation and neuronal loss in a model of ALI.

Unraveling the immune and metabolic changes associated with metritis in dairy cows.

The objective was to unravel the peripartum immune and metabolic changes associated with metritis in Holstein cows. Holstein cows (n = 128) had blood collected at -14, 0, 3, and 7 d relative to parturition (DRP). Flow cytometry was used to evaluate blood leukocyte counts, proportions, and activation.

[Leadless pacemaker implantation. Case report].

We report 67-year-old woman with a sinus node dysfunction and diffuse conduction system disease, with a history of recurrent paroxysmal atrial fibrillation. She was admitted to the Hospital due to palpitations, dizziness, and vertigo, attributing the symptoms to the rhythm disorder described, for which the implantation of a pacemaker was indicated. With a history of tracheal cancer treated with radio and chemotherapy, and chronic steroid therapy for rheumatoid arthritis, she had an important limitation in vascular access for a conventional pacemaker, so, added to a high risk of infection, a decision was made to implant a leadless pacemaker.
