Currently there are few antibacterial dosage regimens established to be safe and effective for sea turtles. Pharmacokinetic evaluation of antibiotics is an essential step in establishing accurate dosage guidelines for a particular species. Metronidazole is an antibiotic that is effective against anaerobic bacteria and some protozoa.

The Hunga Tonga-Hunga/Hunga-Ha'apai eruption on January 15, 2022 sent off a plume of ash material up to the stratosphere and triggered a meteotsunami and barometric pressure pulse that rippled through the atmosphere and oceans all around the world. The nature of the volcanic event and its global impacts on the oceans, atmosphere, lithosphere and the cryosphere are a matter of debate. Here we present a first overview of the time travel of the sound atmospheric pressure wave through the Antarctic continent based on in situ measurements, which represented a unique event observed through the polar ice sheet during the instrumental meteorological era.

Article Synopsis
  • The study investigates how antiviral monoclonal antibodies (mAbs), particularly casirivimab and imdevimab (CAS+IMD), affect immune responses when individuals are vaccinated against SARS-CoV-2 after receiving mAb treatment.
  • It was found that the presence of CAS+IMD during vaccination reduced the effectiveness of the vaccine in generating neutralizing antibodies, though other immune responses remained intact.
  • This reduction in antibody production is linked to "epitope masking," but can be reversed with booster shots, and influences the immune response differently in those who had not yet begun their natural immunity when treated with mAbs.

Diffusion probabilistic models have made their way into a number of high-profile applications since their inception. In particular, there has been a wave of research into using diffusion models in the prediction and design of biomolecular structures and sequences. Their growing ubiquity makes it imperative for researchers in these fields to understand them.

Article Synopsis
  • Pregnant women with COVID-19 are at higher risk for severe outcomes, and this study evaluated the safety and effectiveness of the monoclonal antibody treatment CAS+IMD in this population.* -
  • The study, which involved 82 pregnant participants, found that CAS+IMD was well tolerated with minimal adverse reactions, and it effectively reduced viral loads without significantly affecting fetal development.* -
  • Overall, the treatment showed promising safety and efficacy, suggesting it could be a viable option for managing COVID-19 in pregnant women, although conclusions about its effects are limited due to a small number of placebo recipients.*

Article Synopsis
  • A clinical trial assessed the safety of the combination of casirivimab and imdevimab (CAS + IMD) in children with COVID-19.
  • The results showed that the treatment was well tolerated, similar to findings in adults, with minimal immune response side effects.
  • The study supports further development of advanced monoclonal antibodies for children at higher risk for COVID-19.

Pneumocoelom secondary to primary pulmonary disease was diagnosed via CT (three cases) or radiographs and coelioscopy (one case) in one Kemp's ridley () and three loggerhead () sea turtles. All cases were suspected to be caused by trauma to the lung, and all exhibited positive buoyancy disorders. Coelomocentesis alone was ineffective at resolving each pneumocoelom, suggesting a large and persistent tear in the pulmonary parenchyma.

Background: The field of long COVID research is rapidly evolving, however, tools to assess and monitor symptoms and recovery of the disease are limited. The objective of the present study was to develop a new patient-reported outcomes instrument, the Symptoms Evolution of Long COVID‑19 (SE-LC19), and establish its content validity.

Methods: The 40-item SE-LC19 instrument was developed based on patient-relevant empirical evidence from scientific literature and clinical guidelines that reported symptoms specific to long COVID.

Article Synopsis
  • This pilot study explores the differences in microbiomes and immune responses in patients with chronic pelvic pain (CPP) related to endometriosis versus those with CPP without endometriosis or healthy controls.
  • Researchers collected samples from participants undergoing gynecologic laparoscopy and analyzed them using advanced microbiome sequencing and immune profiling methods, finding notable variations among the groups.
  • Key findings included lower microbiome diversity in both CPP groups compared to controls, specific bacteria associations linked to CPP and endometriosis, and distinctions in patient characteristics like body mass index and ethnic backgrounds.

Introduction: This study aimed to assess the effects of a monoclonal antibody (mAb) combination on symptoms, daily function, and overall health-related quality of life.

Methods: We analyzed patient-reported outcomes data from symptomatic outpatients in a phase 1/2/3 trial. Patients with confirmed SARS-CoV-2 infection and ≥ 1 risk factor for severe COVID-19 received mAb treatment (casirivimab plus imdevimab 1200 mg) or placebo.

Annual health records were retrospectively analyzed for a colony of ring-tailed lemurs () inhabiting St. Catherines Island, Georgia, USA to establish baseline hematological and serum biochemical parameters and determine sex- and age-related differences. Summarized complete blood count and serum biochemistry panel results are presented for 85 blood samples collected from 54 lemurs at annual health exams during 1998-2003.

The use of diaries is known to reduce post-intensive care syndrome in the intensive care unit (ICU) for survivors and families. Studies are needed to explore nurses' experience with diaries. Although the diaries are written for the patient, the diary entries may be helpful for the nurse as well.

Understanding the emotional states of animals is a long-standing research endeavour that has clear applications in animal welfare. Vocalisations are emerging as a promising way to assess both positive and negative emotional states. However, the vocal expression of emotions in birds is a relatively unexplored research area.

Background: While immunotherapy has been highly successful for the treatment of some cancers, for others, the immune response to tumor antigens is weak leading to treatment failure. The resistance of tumors to checkpoint inhibitor therapy may be caused by T cell exhaustion resulting from checkpoint activation.

Methods: In this study, lentiviral vectors that expressed T cell epitopes of an experimentally introduced tumor antigen, ovalbumin, or the endogenous tumor antigen, Trp1 were developed.

The function of the mammalian brain relies upon the specification and spatial positioning of diversely specialized cell types. Yet, the molecular identities of the cell types and their positions within individual anatomical structures remain incompletely known. To construct a comprehensive atlas of cell types in each brain structure, we paired high-throughput single-nucleus RNA sequencing with Slide-seq-a recently developed spatial transcriptomics method with near-cellular resolution-across the entire mouse brain.

This series illustrates how rear-end impact motor vehicle collisions (MVCs) alter the cervical spine's alignment and demonstrates therapeutic use of cervical extension traction to improve lordotic alignment and other outcomes. This is a retrospective reporting of 7 adult patients (4 males and 3 females, 28-42 years) treated for cervical hypolordosis. These subjects received Chiropractic BioPhysics (CBP) rehabilitation and then were involved in a rear-end MVC.
