High cervical spinal cord injuries induce extreme handicap and tactile isolation. Tracheotomised tetraplegic patients are also bound to be olfaction deprived. By restoring negative pressure inspiration, diaphragm pacing (DP) should improve olfaction. We tested olfaction in 10 consecutive tetraplegics during positive pressure mechanical ventilation and DP, using the University of Pennsylvania Sm...

PURPOSE Taste and smell alterations (TSAs) are common symptoms in patients with cancer that may interfere with nutritional intake and quality of life. In this study, we explore and describe how characteristics of self-reported TSAs change in individuals with lung cancer over time using a multiple case study approach to present longitudinal data from individuals. METHODS Patients under investi...

The aim of this study is to compare the use of Beniktol spray and alcohol swab for cord care in our unit. Over a 6-month period (November 2001 to April 2002), all infants whose parents signed the consent form, were enrolled in the study. The nurse randomly used either Beniktol spray or alcohol swab for the baby’s cord care. It was a prospective study designed to compare cord separation time, an...

This study aims to present reflections on the meaning of olfactory sensations and perceptions, as well as their relevance as a phenomenon present in Nursing practice. It stresses the importance of the smells' chemical language in the hospital environment, emphasizing some deductions about the aesthetics of smells from the Nursing perspective. The authors conclude that a deeper aesthetic/philoso...

2,4,5-trimethyl-3-thiazoline (TMT), a component of fox feces, is a widely used odorant to induce innate fear behavior in rats and mice. However, based on the slight acrid smell it was argued that the observed behavioral effects are a result of the aversive and not of the fear-inducing properties of TMT. In the present study, we tried to directly compare the aversive and fear-inducing properties...

In this paper we explore relevant electrical properties of two olfactory receptors (ORs), one from rat OR I7 and the other from human OR 17-40, which are of interest for the realization of smell nanobiosensors. The investigation compares existing experiments, coming from electrochemical impedance spectroscopy, with the theoretical expectations obtained from an impedance network protein analogue...

How, and for whom, does disgust influence moral judgment? In four experiments participants made moral judgments while experiencing extraneous feelings of disgust. Disgust was induced in Experiment 1 by exposure to a bad smell, in Experiment 2 by working in a disgusting room, in Experiment 3 by recalling a physically disgusting experience, and in Experiment 4 through a video induction. In each c...

Abstract Background Olfactory and taste dysfunctions have been identified as prominent signs of COVID-19 infection. The data on its prevalence, time onset, recovery is highly variable. Objective study was aimed at establishing the incidence factors influencing smell disorders in COVID-19-affected patients. Methodology Telephonic interviews were used to collect symptoms COVID-19-positive patient...

Introduction: The Questionnaire for Olfactory Dysfunction (QOD) is a self-reporting olfactory-related quality of life questionnaire. The aim of this study was to determine the reliability and validity of the Persian version of this questionnaire. Materials and Methods: One hundred and thirteen patients with olfactory problems were enrolled in this study. The English version of the QOD was first...
