Identification of novel genetic, neurobiological and radio-anatomical biomarkers for risk stratification of sudden unexpected death in infancy and early childhood: the BIOMINRISK study protocol.

Introduction: The BIOMINRISK project is a national French study aimed at identifying novel biomarkers associated with sudden unexpected death in infancy (SUDI) through a multidisciplinary approach encompassing three key components of intrinsic vulnerability to SUDI: genetic, neurobiological and radio-anatomical. A better understanding of the pathophysiological mechanisms underlying SUDI may enhance the personalisation of prevention strategies and contribute to reducing its incidence.

Methods And Analysis: We will analyse data from 250 children under the age of 2 included in the national SUDI registry (the OMIN registry) since 2020 for which biological samples and medical imaging data will have been collected from 15 participating French hospitals.

Development of an ophthalmic solution combining allogenic plasma with protective excipients for enhanced therapeutic role in the management of ocular surface diseases.

Ocular surface diseases (OSDs) are characterised by an instability of the tear film. In severe cases, these disorders have been improved by using human serum or plasma formulated into eye drops. These blood-derived-products present a biological composition similar to that of tears and contain beneficial factors that modulate inflammation and tissue regeneration.

Background: The present study evaluated the diagnostic and prognostic value of biomarkers, including soluble forms of the receptor for advanced glycation end-products (s-RAGE), soluble urokinase plasminogen activator receptor (SuPAR), and others, for the occurrence of early-onset acute kidney injury (EO-AKI), EO-AKI non-recovery, day-90 major adverse kidney events (MAKE-90), and day-90 mortality in critically ill patients with Coronavirus Disease-19 (Covid-19).

Methods: A single-center, prospective study was conducted at the University Hospital of Clermont-Ferrand, France, between March 2020 and February 2021. The study included adult patients suffering from severe pneumonia caused by the SARS-CoV-2 virus, who were admitted to the hospital's intensive care unit.

Can the Association of the Biomarkers GFAP and UCH-L1 Predict Intracranial Injury After Mild Traumatic Brain Injury in Adults? A Systematic Review and Meta-Analysis.

Study Objectives: Brain biomarkers have been used to predict intracranial injury in both adults and children following mild traumatic brain injury (mTBI). Several biomarkers have been evaluated, including S100B, NfL, Tau, glial fibrillary acidic protein (GFAP), and ubiquitin carboxy-terminal hydrolase L1 (UCH-L1). The combined measurement of GFAP and UCH-L1 has recently been recommended by scientific societies, but no meta-analysis on the topic has been performed yet.

[Studying daratumumab's interference in serum protein electrophoresis: two case reports].

An 86-year-old woman is monitored for IgA λ-associated multiple myeloma, treated in second intention with dexamethasone, revlimid and daratumumab after a relapse. A control serum protein electrophoresis detects the presence of a new monoclonal spike, later confirmed by immunofixation as an IgG κ. Suspecting an interference due to the immunotherapy, a daratumumab specific immunofixation reflex assay (DIRA) is performed, with the addition of anti-daratumumab antibodies, confirming the interference.

The anti-inflammatory effect of the amniotic PPARγ pathways is not dysregulated by the alternative plasticizer DINCH and its metabolite MINCH in human fetal membranes.

Plasticizers, particularly phthalates, are widely used to enhance the properties of plastics, yet their harmful effects on human health, especially reproductive health, have raised concerns. This has led governments to promote the use of non-phthalate substitutes. Preterm premature rupture of fetal membranes (PPROM), affecting 3-4% of pregnancies and contributing to 40-50% of preterm births worldwide, has been associated with traditional phthalate exposure.

[French Society of Clinical Biology (SFBC) guidelines on point-of-care testing].

The "Emergency Biology" working group of the French Society of Clinical Biology (SFBC) presents in this article its recommendations for the application of article L6211-18 of the Public Health Code, when the analytical phase of a medical biology examination cannot be carried out in a medical laboratory within a time frame compatible with the patient's state of health. A proposal for a list of examinations that may be carried out outside the laboratory (point-of-care testing - POCT) is made, by associating the elements justifying this delocalization: clinical contexts concerned and maximum time limits for carrying out the examination in these contexts if the examination is carried out within the LBM. These recommendations are to be adapted within the framework of local clinic biological agreements.

Physicochemical Properties and Bioreactivity of Sub-10 μm Geogenic Particles: Comparison of Volcanic Ash and Desert Dust.

Exposure to ambient particulate matter (PM) with an aerodynamic diameter of <10 μm (PM) is a well-established health hazard. There is increasing evidence that geogenic (Earth-derived) particles can induce adverse biological effects upon inhalation, though there is high variability in particle bioreactivity that is associated with particle source and physicochemical properties. In this study, we investigated physicochemical properties and biological reactivity of volcanic ash from the April 2021 eruption of La Soufrière volcano, St.

An Evaluation of a Point-of-Care GEM Premier ChemSTAT Analyzer in an Emergency Department: Prevention of Contrast-Induced Nephropathy and Optimization of Patient Flow.

Having a laboratory renal profile for medical imaging examinations requiring contrast media (CM) administration is strongly advised. Creatinine helps identify patients at risk of contrast-induced nephropathy (CIN). The GEM Premier™ ChemSTAT (Werfen) is a point-of-care (POC) analyzer with 12 emergency parameters, including a creatinine assay.

Serum GFAP and UCH-L1 for the identification of clinically important traumatic brain injury in children in France: a diagnostic accuracy substudy.

Background: Many children with mild traumatic brain injury (mTBI), defined by a Glasgow Coma Scale (GCS) score between 13 and 15, undergo hospitalisation or cranial CT (CCT) scans despite the absence of clinically important traumatic brain injury (ciTBI; ie, hospitalisation >2 days associated with intracranial lesions on CCT, neurosurgical intervention, intensive care admission, or death). Clinical algorithms have reduced CCT scans and hospitalisations by 10%. We aimed to established age-appropriate reference values for GFAP and UCH-L1 and evaluate their diagnostic test performance in identifying ciTBI in children.

Application of Fetal Membranes and Natural Materials for Wound and Tissue Repair.

The human fetal membrane is a globally accepted biological biomaterial for wound and tissue repair and regeneration in numerous fields, including dermatology, ophthalmology, and more recently orthopedics, maxillofacial and oral surgery, and nerve regeneration. Both cells and matrix components of amnion and chorion are beneficial, releasing a diverse range of growth factors, cytokines, peptides, and soluble extracellular matrix components. Beside fetal membranes, numerous natural materials have also been reported to promote wound healing.

Clustering based on renal and inflammatory admission parameters in critically ill patients admitted to the ICU.

Introduction: The COVID-19 pandemic has been associated with significant variability in acute kidney injury (AKI) incidence, leading to concerns regarding patient heterogeneity. The study's primary objective was a cluster analysis, to identify homogeneous subgroups of patients (clusters) using baseline characteristics, including inflammatory biomarkers. The secondary objectives were the comparisons of MAKE-90 and mortality between the different clusters at three months.

Objectives: To assess the variations and diagnostic performance of serum biomarkers of neurodegenerative diseases.

Methods: In this monocentric prospective study, neurofilament light (NFL), T-tau, p-tau181, p-tau217, Aβ40, and Aβ42 were measured in serum collected from orthopedic patients (control group, n=114) and patients in the neurology department (n=69) previously diagnosed with Alzheimer's disease (AD, n=52), parkinsonian syndromes (n=10), and other etiologies of neurodegeneration (non-AD, n=7).

Results: In the control group, serum NFL, T-tau, p-tau181, p-tau217, and Aβ40 significantly increased with age, independently of sex.

[Methadone-induced central adrenal insufficiency: a case report].

Adrenal insufficiency secondary to opioid use remains inadequately acknowledged in medical literature. We present the case of a 33-year-old female patient diagnosed with central adrenal insufficiency (CAI), where methadone use was identified as the underlying cause after ruling out known etiologies. This article aims to enhance awareness among prescribing clinicians and medical professionals regarding the potential occurrence of AI in patients undergoing methadone treatment.

Performance of glial fibrillary acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) biomarkers in predicting CT scan results and neurological outcomes in children with traumatic brain injury (BRAINI-2 paediatric study): protocol of a European prospective multicentre study.

Introduction: In light of the burden of traumatic brain injury (TBI) in children and the excessive number of unnecessary CT scans still being performed, new strategies are needed to limit their use while minimising the risk of delayed diagnosis of intracranial lesions (ICLs). Identifying children at higher risk of poor outcomes would enable them to be better monitored. The use of the blood-based brain biomarkers glial fibrillar acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase-L1 (UCH-L1) could help clinicians in this decision.

Consensus paper on the assessment of adult patients with traumatic brain injury with Glasgow Coma Scale 13-15 at the emergency department: A multidisciplinary overview.

Traumatic brain injury (TBI) is a common reason for presenting to emergency departments (EDs). The assessment of these patients is frequently hampered by various confounders, and diagnostics is still often based on nonspecific clinical signs. Throughout Europe, there is wide variation in clinical practices, including the follow-up of those discharged from the ED.
