Article Synopsis
  • The European hedgehog is declining in population, prompting conservation efforts, and this study focused on understanding the causes of death in hedgehogs admitted to a French rehabilitation center.
  • Out of 159 dead hedgehogs analyzed, 92% had identifiable causes of death, with impaired condition (30%), bacterial infections (26%), and trauma (20%) being the most common.
  • The study also found significant exposure to toxicants, such as anticoagulant rodenticides in 42% of hedgehogs, alongside a low prevalence of blood pathogens, emphasizing the need for further investigations into the health and ecological factors affecting hedgehog populations.

Article Synopsis
  • - The study aimed to create a population pharmacokinetic-pharmacodynamic (PK-PD) model to understand how different factors influence the variability of unfractionated heparin (UFH) doses in patients undergoing radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF).
  • - Analysis of medical records from 668 patients revealed that pretreatments with anticoagulants like dabigatran, warfarin, or fluindione affected baseline activated clotting time (ACT), and the initial UFH dose and previous anticoagulant were key predictors of ACT 15 minutes after UFH administration.
  • - The researchers successfully developed predictive calculators for ACT and UFH doses, promoting tailored anticoagulation

Article Synopsis
  • The study investigates how to equalize the exercise-induced dose in resistance training by comparing methods based on total weight lifted and sets performed until failure.
  • Twelve trained participants completed five bench-press sessions, manipulating load and set endpoints to analyze differences in total weight and sets taken to failure.
  • Findings suggest that matching exercise density can reduce discrepancies in sets performed, but current volume equalization methods may lead to imbalanced training efforts; customizing training volume to each exercise's maximum can improve protocol equalization.

Purpose: The prevalence of type 2 diabetes mellitus (T2DM) in cancer patients is high. During the medication review process, clinical pharmacists could detect and manage drug-related problems (DRP) to optimize pharmacotherapy but there is a need to standardize pharmacists' interventions (PI) especially for T2DM-related DRP. The present study aims to describe DRP in cancer patients with T2DM undergoing anticancer treatment (AT) and to propose related preliminary guidelines to manage T2DM-related DRP.

are vectors that can transmit many different pathogens to mammals - including humans, and domestic and wild animals - and birds. In order to take preventive measures against any vector-borne disease, it is important to gather information on both the host and vector species. species are mainly mammalophilic, ornithophilic or ornithophilic/mammalophilic, but females have also been found to occasionally feed on engorged insects.

Antibiofilm approaches as a new paradigm for treating infections.

Prog Biomed Eng (Bristol)

April 2024

Machine Biology Group, Departments of Psychiatry and Microbiology, Institute for Biomedical Informatics, Institute for Translational Medicine and Therapeutics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, United States of America.

The lack of effective antibiotics for drug-resistant infections has led the World Health Organization to declare antibiotic resistance a global priority. Most bacterial infections are caused by microbes growing in structured communities called biofilms. Bacteria growing in biofilms are less susceptible to antibiotics than their planktonic counterparts.

Background: Phlebotomine sand flies (Diptera: Psychodidae) are important vectors of various pathogens, mainly Leishmania parasites. In the Old World, the most important genus in term of pathogens transmission is the genus Phlebotomus, which includes many proven or suspected vectors of several Leishmania species, while the genus Sergentomyia remains so far unproven as a vector of human pathogens. Algeria is one of the most affected countries by human leishmaniasis.

Article Synopsis
  • Leptospirosis is a disease caused by bacteria, with gaps in knowledge about its main animal hosts.
  • A study in France looked into the prevalence of Leptospira bacteria in raccoons, an invasive species there.
  • Out of 141 raccoons tested, only 5% were positive for the bacteria, indicating they are likely accidental hosts rather than primary carriers.

We have investigated the impact of gemcitabine (Gem) and deuterated gemcitabine-squalene (GemSQ-d6) nanoparticles (NPs) on MCF7 and MDA-MB-231 breast cancer cell lines by Raman spectroscopy. Quantification of LDL expression levels in both cell lines revealed a four-fold increase in MDA-MB-231 cells compared to MCF7 cells. In in vitro antitumor assessments, Gem displayed 13.

Magnetic resonance imaging (MRI) is a powerful tool for observing and assessing the properties of brain tissue and structures. In particular, in the context of neonatal care, MR images can be used to analyze neurodevelopmental problems that may arise in premature newborns. However, the intrinsic properties of newborn MR images, combined with the high variability of MR acquisition in a clinical setting, result in complex and heterogeneous images.

Mooren's ulcer is a painless and idiopathic ulcer of the peripheral cornea related to autoimmunity against a corneal stromal antigen, calgranulin C. Corneal involvement is isolated. There are no specific histopathological features to differentiate Mooren's ulcer from pseudo-Mooren's, the latter being part of a systemic disease.

Background: Any surgical procedure carries a risk for venous thromboembolism (VTE), albeit variable. Improvements in medical and surgical practices and the shortening of care pathways due to the development of day surgery and enhanced recovery after surgery, have reduced the perioperative risk for VTE.

Objective: A collaborative working group of experts in perioperative haemostasis updated in 2024 the recommendations for the Prevention of perioperative venous thromboembolism published in 2011.

Purpose: This review systematically investigates the role of radiomics in radiotherapy, with a particular emphasis on the use of quantitative imaging biomarkers for predicting clinical outcomes, assessing toxicity, and optimizing treatment planning. While the review encompasses various applications of radiomics in radiotherapy, it particularly highlights its potential for guiding reirradiation of recurrent cancers.

Methods: A systematic review was conducted based on a Medline search with the search engine PubMed using the keywords "radiomics or radiomic" and "radiotherapy or reirradiation".

Understanding lignocellulosic biomass resistance to enzymatic deconstruction is crucial for its sustainable conversion into bioproducts. Despite scientific advances, quantitative morphological analysis of plant deconstruction at cell and tissue scales remains under-explored. In this study, an original pipeline is devised, involving four-dimensional (space  + time) fluorescence confocal imaging, and a novel computational tool, to track and quantify deconstruction at cell and tissue scales.

This randomized controlled trial investigated the impact of a brief session of group-based running on feelings of energy and fatigue, comparing exercise in a local nature reserve versus an outdoor built environment, and a sedentary control condition. Sixty-six physically active university students participated, with 56 providing full data for each time point. Consistent with previous research, participants in both exercise groups reported significantly increased energy and decreased fatigue compared to those in the sedentary control group.

The prejudices often associated with the perception of people with disability can limit their access to the opportunities and resources available in society, leading them to live in a climate of great socio-economic uncertainty exacerbated since the COVID-19 pandemic. This research focuses on the perceptions of young people in France, defined as those aged between 18 and 30, towards people with disability. The study draws on the principles of social psychology to understand these perceptions, the factors that influence them and the most effective ways of promoting greater inclusion.
