Impacts of sensory multimodality congruence and familiarity with short use on cosmetic product evaluation.

Cross-modal association between sensory modalities is a natural phenomenon in the perception of our environment. For cosmetic evaluation, touch and smell are the two major sensory modalities involved in the whole product perception. In this study, we investigate whether a specific cosmetic texture is preferentially associated with a specific fragrance: congruence between texture and fragrance.

And I'm feeling good: effect of emotional sweat and perfume on others' physiology, verbal responses, and creativity.

Emotions can be communicated in social contexts through chemosignals contained in human body odors. The transmission of positive emotions via these signals has received little interest in past research focused mainly on negative emotional transmission. Furthermore, how the use of perfumed products might modulate this transmission remains poorly understood.

Association between prehospital shock index and mortality among patients with COVID-19 disease.

Background: There exists a need for prognostic tools for the early identification of COVID-19 patients requiring intensive care unit (ICU) admission and mortality. Here we investigated the association between a clinical (initial prehospital shock index (SI)) and biological (initial prehospital lactatemia) tool and the ICU admission and 30-day mortality among COVID-19 patients cared for in the prehospital setting.

Methods: We retrospectively analysed COVID-19 patients initially cared for by a Paris Fire Brigade advanced (ALS) or basic life support (BLS) team in the prehospital setting between 2020, March 08th and 2020, May 30th.

Beyond olfaction: Beneficial effects of olfactory training extend to aging-related cognitive decline.

Studies on olfactory training (OT) outcomes have mostly been limited to olfactory performance, while direct neural connections between olfactory system and amygdala-hippocampal complex allow expecting OT to have psychological effects. To address this hypothesis, we examined olfactory, cognitive and emotional effects of OT in the group of 68 subjects aged between 50 and 88 years ( = 62.8 ± 8.

Variations in the TRPV1 gene are associated to exertional heat stroke.

Objectives: Exertional Heat Stroke (EHS) is one of the top three causes of sudden death in athletes. Extrinsic and intrinsic risk factors have been identified but the genetic causes still remain unclear. Our aim was to identify genes responsible for EHS, which is a necessary step to identify patients at risk and prevent crises.

French Policies for Victim Management During Mass Radiological Accidents/Attacks.

In the current international context, emergency medical services have to be prepared for chemical, biological, radiological, and nuclear events. Emergency response to radiological or nuclear events requires coordination between many components: the fire brigade, emergency medical services (including nurses and physicians), police, hospitals, etc. To optimize efficiency, victim management in France is governed by specific policies and planned responses.

Is there a link between exertional heat stroke and susceptibility to malignant hyperthermia?

Objective: The identification of a predisposition toward malignant hyperthermia (MH) as a risk factor for exertional heat stroke (EHS) remains a matter of debate. Such a predisposition indicates a causal role for MH susceptibility (MHS) after EHS in certain national recommendations and has led to the use of an in vitro contracture test (IVCT) to identify the MHS trait in selected or unselected EHS patients. The aim of this study was to determine whether the MHS trait is associated with EHS.

Is muscle energy production disturbed in exertional heat stroke?

Background: Exertional heat stroke (EHS) is a life-threatening disease that shares some clinical similarities with malignant hyperthermia (MH). By use of (31)Phosphorus magnetic resonance spectroscopy (MRS), EHS patients with MH susceptibility and MH patients shared common metabolic abnormalities. The aim of this study was to determine whether subjects who suffered from an EHS episode had disturbed muscle energetics.

Report of 182 cases of exertional heatstroke in the French Armed Forces.

Objectives: Exertional heatstroke (EHS) remains a major problem for the military. The aim of our study was to describe medical history and clinical and biological features of EHS in a large military cohort.

Methods: We conducted a retrospective study among military subjects admitted to the Military Teaching Hospital Laveran for EHS from 2004 to 2006.

Psychological and physiological evaluation of emotional effects of a perfume in menopausal women.

In the present study, we familiarized menopausal women with a pleasant smell in the skin care products, they used for 1 week and assessed whether their mood and emotions improved using behavioural and physiological tools. Eventually, we studied the effects of inhaling the familiar fragrance on physiological response of the subjects. An anhedonia questionnaire was used to distinguish the effects of the test products according to low vs.
