Hard-to-heal wounds are a problem for both patients and caregivers. The biofi lm is one of the local factors of delayed healing. Wound hygiene carried out in 4 steps (cleansing, debridement, refashion - care of the edges, and dressing) constitutes the basis of proactive and curative anti-biofi lm strategies.

Use of multilayer silicone foam dressings as adjuvant therapy to prevent pressure injuries.

Despite progress in the prevention of pressure injuries (PIs), they remain a challenging public health problem because of their frequency and morbidity. Protection of the skin by multilayer silicone foam dressings may be an adjuvant measure to prevent PIs in high-risk patients. Despite the available clinical data and published recommendations on this measure, caregivers face difficulties in identifying patients who would benefit from this adjuvant measure.

Arterial Thrombotic Events in Adult Inpatients With COVID-19.

Objective: To evaluate the clinical course of and risk factors for arterial thrombotic events in adult inpatients with coronavirus disease 2019 (COVID-19).

Methods: All consecutive adult patients admitted for COVID-19 infection in a referral center in France and discharged from the hospital between April 1 and April 30, 2020, were included. All arterial thrombotic events that occurred through discharge were considered for analysis.

Glucocorticoids with low-dose anti-IL1 anakinra rescue in severe non-ICU COVID-19 infection: A cohort study.

Background: The optimal treatment for patients with severe coronavirus-19 disease (COVID-19) and hyper-inflammation remains debated.

Material And Methods: A cohort study was designed to evaluate whether a therapeutic algorithm using steroids with or without interleukin-1 antagonist (anakinra) could prevent death/invasive ventilation. Patients with a ≥5-day evolution since symptoms onset, with hyper-inflammation (CRP≥50mg/L), requiring 3-5 L/min oxygen, received methylprednisolone alone.

A curable pseudo-dementia related to an atypical presentation of giant cell arteritis.

A 70-year-old patient was admitted with rapidly progressive cognitive decline associated with limitations in activities of daily living, weight loss and cerebellar ataxia. The diagnosis of giant cell arteritis (GCA) with vascular involvement was made, based on the presence of a metabolically active vasculitis of the brachiocephalic trunk on 18FDG-PET imaging. Temporal artery biopsy also revealed pan-arteritis.

Discovery and Lead-Optimization of 4,5-Dihydropyrazoles as Mono-Kinase Selective, Orally Bioavailable and Efficacious Inhibitors of Receptor Interacting Protein 1 (RIP1) Kinase.

RIP1 kinase regulates necroptosis and inflammation and may play an important role in contributing to a variety of human pathologies, including inflammatory and neurological diseases. Currently, RIP1 kinase inhibitors have advanced into early clinical trials for evaluation in inflammatory diseases such as psoriasis, rheumatoid arthritis, and ulcerative colitis and neurological diseases such as amyotrophic lateral sclerosis and Alzheimer's disease. In this paper, we report on the design of potent and highly selective dihydropyrazole (DHP) RIP1 kinase inhibitors starting from a high-throughput screen and the lead-optimization of this series from a lead with minimal rat oral exposure to the identification of dihydropyrazole 77 with good pharmacokinetic profiles in multiple species.

[The prescribing of dressings].

Dressings must be prescribed as accurately as possible, whether the prescription is written by a nurse or by a doctor. The pharmacist is then able to dispense the exact product prescribed. Knowledge of the different classes of dressings and their indications ensures the adapted management of chronic and acute wounds.

Pharmacological properties of acid N-thiazolylamide FFA2 agonists.

FFA2 is a receptor for short-chain fatty acids. Propionate (C3) and 4-chloro-α-(1-methylethyl)-N-2-thiazolyl-benzeneacetamide (4-CMTB), the prototypical synthetic FFA2 agonist, evoke calcium mobilization in neutrophils and inhibit lipolysis in adipocytes via this G-protein-coupled receptor. 4-CMTB contains an N-thiazolylamide motif but no acid group, and 4-CMTB and C3 bind to different sites on FFA2 and show allosteric cooperativity.

Discovery of novel indazole derivatives as dual angiotensin II antagonists and partial PPARγ agonists.

Identification of indazole derivatives acting as dual angiotensin II type 1 (AT1) receptor antagonists and partial peroxisome proliferator-activated receptor-γ (PPARγ) agonists is described. Starting from Telmisartan, we previously described that indole derivatives were very potent partial PPARγ agonists with loss of AT1 receptor antagonist activity. Design, synthesis and evaluation of new central scaffolds led us to the discovery of pyrrazolopyridine then indazole derivatives provided novel series possessing the desired dual activity.

Acquired deforming hypertonia and contractures in elderly subjects: definition and prevalence in geriatric institutions (ADH survey).

Objective: By proposing a new terminology (acquired deforming hypertonia or ADH) and a new definition for contractures, the main objective of this study was to establish their prevalence among institutionalized elderly patients. Secondary objectives were to analyze the negative impact of ADH and collect the opinions of clinicians on the possible treatments available.

Methodology: A multicenter cross-sectional study was conducted among residents of 39 geriatric institutions (29 EHPAD and 10 USLD).

An atypical Clostridium strain related to the Clostridium botulinum group III strain isolated from a human blood culture.

A nontoxigenic strain isolated from a fatal human case of bacterial sepsis was identified as a Clostridium strain from Clostridium botulinum group III, based on the phenotypic characters and 16S rRNA gene sequence, and was found to be related to the mosaic C. botulinum D/C strain according to a multilocus sequence analysis of 5 housekeeping genes.

[Physiopathology of pressure ulcers].

Pressure ulcers occur mainly in people over the age of 70 and in a specific context. There are different types, various stages and several known risk factors.This article studies a complex concept which requires specific knowledge.

Superabsorbent dressings for copiously exuding wounds.

Exudate control is important in the management of both acute and chronic wounds. A new category of absorbent dressings that contain superabsorbent particles promises high absorbency. The aim of this multicentre, prospective, non-comparative observational study was to evaluate the clinical efficacy and absorbent capacity of a superabsorbent dressing.

French national wound management survey: choice criteria of dressings.

Across Europe, wound care management is organized differently, and in some countries such as the UK or Denmark, wound healing centres have been implemented. In France, a large number of health professionals are not sufficiently educated in wound care management during their vocational training. The rapid evolution of dressings has changed wound management practices and has given rise to new professional recommendations.

Synthesis and biological activities of novel indole derivatives as potent and selective PPARgamma modulators.

Starting from the structure of Telmisartan, a new series of potent and selective PPARgamma modulators was identified. The synthesis, in vitro and in vivo evaluation of the most potent compounds are reported and the X-ray structure of compound 7b bound to the PPARgamma ligand binding domain is described.

The discovery of equipotent PPARalpha/gamma dual activators.

We report the design and synthesis of equipotent PPARalpha/gamma dual agonists starting from selective PPAR alpha agonist 1. In vivo data for 7 in the Zucker fa/fa rat are presented.

Phase 2 study of a new Hydrofiber dressing for superficial chronic or acute wounds.

Objective: To evaluate the safety and performance of MedicelTulle Dressing (MTD) in subjects with chronic or acute wounds left to heal by secondary intention.

Method: This 28-day, multi-centre, single-arm clinical study was conducted at seven sites in France. Thirty patients with a chronic (n = 20) or acute wound (n = 10) were treated with MTD and gauze as a secondary dressing.
