CIBERINFEC, ISCIII - CIBER Infectious Diseases, Health Institute Carlos III, Madrid, Spain; Parasitology Reference and Research Laboratory, Spanish National Centre for Microbiology, Health Institute Carlos III, Majadahonda, Madrid, Spain.

Recent molecular and metagenomic studies have revealed that the obligate anaerobic protist Blastocystis is found more prevalently and with higher subtype diversities in herbivore species than in carnivore species. However, information on wild carnivore species is scarce. Here, we investigated the presence of Blastocystis by molecular methods in fecal DNA samples of free-ranging and captive Iberian lynxes from Spain (n = 243) and Portugal (n = 30).

Influence of Physical Exercise on the Rehabilitation of Volumetric Muscle Loss Injury Reconstructed with Autologous Adipose Tissue.

J Funct Morphol Kinesiol

October 2024

Department of Morphological Sciences, Section of Histology, Faculty of Medicine and Nursing, Maimonides Institute for Biomedical Research IMIBIC, Reina Sofía University Hospital, University of Cordoba, 14004 Cordoba, Spain.

Background: In volumetric muscle loss (VML) injuries, spontaneous muscle regeneration capacity is limited. The implantation of autologous adipose tissue in the affected area is an option to treat these lesions; however, the effectiveness of this therapy alone is insufficient for a complete recovery of the damaged muscle. This study examined the influence of treadmill exercise on the rehabilitation of VML injuries reconstructed with autologous adipose tissue, as a strategy to counteract the limitations of spontaneous regeneration observed in these injuries.

Article Synopsis
  • Angiotensin II (Ang II) is crucial for blood pressure regulation, and a modified version called pyruvamide-Ang II (Ang P), created with a cheaper vitamin B derivative (pyridoxal-5'-phosphate), may provide a cost-effective treatment for hypertension.
  • Studies showed that Ang P leads to lower calcium entry in vascular smooth muscle cells and has a weaker binding affinity to the angiotensin II type 1 receptor, resulting in less vasoconstriction compared to traditional Ang II.
  • In tests on rats, using PLP significantly reduced blood pressure in spontaneously hypertensive rats and prevented blood pressure spikes in normal rats when treated with both Ang II and PLP, suggesting

Vet Res

October 2024

Parasitology Reference and Research Laboratory, Spanish National Centre for Microbiology, Health Institute Carlos III, Majadahonda, Madrid, Spain.

Article Synopsis
  • The rise in wild boar populations in Europe is leading to increased human-wildlife conflicts and the potential for spreading diseases, particularly the protist Blastocystis, which can cause gastrointestinal issues in both animals and humans.
  • A study was conducted on 459 wild boar faecal samples from Spain and Portugal, revealing a 15.3% overall Blastocystis infection rate, with a significantly higher prevalence in Portugal (34.3%) compared to Spain (10.0%).
  • Seven different Blastocystis subtypes were found, with ST5 being the most common, indicating that wild boars can be significant carriers of zoonotic pathogens that may pose public health risks.

Calcitriol and calcimimetics are used to treat hyperparathyroidism secondary to chronic kidney disease (CKD). Calcitriol administration and the subsequent increase in serum calcium concentration decrease parathyroid hormone (PTH) levels, which should reduce bone remodeling. We have previously reported that, when maintaining a given concentration of PTH, the addition of calcimimetics is associated with an increased bone cell activity.

Department of Organic Chemistry, Center for Research in Biological Chemistry and Molecular Materials, Santiago de Compostela University, CIQUS, Spain. Electronic address:

Background: The ongoing issues with post-COVID conditions (PCC), where symptoms persist long after the initial infection, highlight the need for research into blood lipid changes in these patients. While most studies focus on the acute phase of COVID-19, there's a significant lack of information on the lipidomic changes that occur in the later stages of the disease. Addressing this knowledge gap is critical for understanding the long-term effects of COVID-19 and could be key to developing personalized treatments for those suffering from PCC.

Article Synopsis
  • Major non-viral causes of diarrhea in humans and animals include specific protozoan species, but there's a lack of data on these in free-ranging carnivores, especially the endangered Iberian lynx.
  • In a study of Iberian lynxes in Spain, two protozoan species were detected in small percentages of individuals, indicating the presence of both rodent/leporid-adapted and zoonotic variants.
  • The findings highlight the Iberian lynx's role as a host for these parasites, though the risk of human transmission appears low, pointing to the need for further research on the impact of these infections on the species' health.

This observation provides comprehensive data on the clinical correlates of both cytomegalovirus (CMV) genotypic follow-up and clinical monitoring and outcomes for two different solid organ transplantation recipients that received letermovir as secondary prophylaxis. Our study emphasizes that monitoring of CMV disease in the patient and early genotypic detection of resistance mutations are essential when using new antiviral drugs for off-label indication in patients experiencing CMV relapses or not responding to standard antiviral therapy. These cases and the bibliography reviewed can be helpful for other researchers and clinicians working in the field to optimize the use of new treatments for transplant recipients since drug-resistant CMV infection is an important emerging problem even with new developments in antiviral treatment.
