Can You Smell Me Now: Towards a Remote Olfactory Study

The sense of smell-olfaction involves the natural processing of ambient information in real-time. This process allows humans to detect danger, identify familiarities, and form lasting memories. During the COVID-19 pandemic, researchers were presented with challenges related to conducting in-person olfactory-based user studies. In this paper, we explore user experience and perception during olfactory-based interactions (OBI). Based upon previous literature, we propose an approach to offer future researchers a methodology for conducting olfactory-based user studies remotely. In particular, we explored a paper prototyping medium as an olfactory display. This experiment demonstrates the remote investigation of a complex sensory functionality during high mental work-load levels while participants (N=12) engage in an online memory game. Furthermore, this work seeks to inspire further discussion of olfactory-based user studies that explore functions related to human moods, memory, and behavior.

Use of Topical Lavender Essential Oils to Reduce Perceptions of Burnout in Critical Care.

BACKGROUND: Intensive care unit (ICU) health care workers face increased burnout. The purpose of this project was to evaluate burnout after implementing lavender essential oils. OBJECTIVE: To assess the effectiveness of topical lavender essential oils in decreasing the instance of burnout in frontline ICU health care workers during the COVID-19 pandemic. METHODS: A predesign and postdesign evidence-based practice project was conducted to evaluate the implications of an 8-week topical lavender oil intervention on health care worker burnout. The Maslach Burnout Inventory, including subscales of emotional exhaustion, depersonalization, and personal accomplishment, was administered before and after the intervention. Health care workers' compliance and satisfaction with the intervention were also measured. RESULTS: Thirty-four ICU health care workers participated. Results showed significant improvements in the personal accomplishment subscale (mean [SD], 3.86 [0.81] before vs 4.14 [1.01] after intervention; P = .04). Improvements in depersonalization were not significant. Most participants were satisfied (n = 23 [67.6%]) and compliant (n = 23 [67.6%]) with the intervention. CONCLUSION: The use of topical lavender essential oils is a cost-effective intervention that can be used to decrease components of burnout in frontline ICU workers.

Disparities in Olfactory Dysfunction in African American Individuals During COVID-19 Pandemic

Introduction: COVID-19 is known to cause olfactory dysfunction (OD). African American individuals have been disproportionately impacted by the COVID-19 pandemic. To reduce health disparities related to OD, it is important to have accurate objective testing, especially for African American individuals, who have a higher disease burden. Our objective is to examine olfactory performance in African American and White study participants by comparing individual scent scores to assess potential cultural appropriateness of scent selection. Method(s): This was a cross-sectional study of healthy participants from June 2021 to April 2022. Two smelling tests were used: Affordable Rapid Olfactory Measurement Array (AROMA) and Sniffin' Sticks (SST-12). Pearson correlation and chi2 tests were used to detect statistical differences. African American and White participants without sinonasal disease aged 18+ were recruited from outpatient clinics at Kansas University Medical Center and the community. The main outcome for our study is olfactory performance on smelling tests. Result(s): Of the 102 participants, 46 were African American and 56 were White. AROMA and SST-12 scores were significantly correlated in African American (P<.01) and White (P<.01) participants. African American participants scored significantly lower than their White counterparts on both tests (P<.01). AROMA, mean scores were 64.2 and 75.5 for African American and White participants, respectively. SST-12 mean scores were 84.2 and 89.9 for African American and White participants, respectively. On SST-12, 60.9% of African American and 30.4% of White participants were hyposmic, (P<.05). For 6 AROMA scents (licorice, orange, lavender, cinnamon, clove, and rosemary) and 1 SST-12 scent (pineapple) African American participants scored significantly lower than White participants (P<.05). Conclusion(s): When compared with White participants, African American participants performed worse on both smelling tests and a greater proportion were considered hyposmic. African American participants performed significantly worse than their White counterparts on several scents, raising the issue of cultural appropriateness of scents used in olfactory testing.

Thidiazuron: New Trends and Future Perspectives to Fight Xylella fastidiosa in Olive Trees.

These days, most of our attention has been focused on the COVID-19 pandemic, and we have often neglected what is happening in the environment. For instance, the bacterium Xylella fastidiosa re-emerged as a plant pathogen of global importance in 2013 when it was first associated with an olive tree disease epidemic in Italy, called Olive Quick Decline Syndrome (OQDS), specifically caused by X. fastidiosa subspecies pauca ST53, which affects the Salento olive trees (Apulia, South-East Italy). This bacterium, transmitted by the insect Philaenus spumarius, is negatively reshaping the Salento landscape and has had a very high impact in the production of olives, leading to an increase of olive oil prices, thus new studies to curb this bacterium are urgently needed. Thidiazuron (TDZ), a diphenylurea (N-phenyl-1,2,3-thiadiazol-5-yl urea), has gained considerable attention in recent decades due to its efficient role in plant cell and tissue culture, being the most suitable growth regulator for rapid and effective plant production in vitro. Its biological activity against bacteria, fungi and biofilms has also been described, and the use of this low-cost compound to fight OQDS may be an intriguing idea.

Upper airways: association between olfactory training and quality of life in patients with impaired sense of taste and smell following COVID-19

Background: Loss of the sense of taste and smell occurs in 65-88% of patients infected with corona virus. In contrast to previous post-viral olfactory loss, it is often younger patients with milder symptoms of COVID-19, who experience chemosensory dysfunction. The duration of the impaired sense of taste and smell ranges from a few days to weeks after the end of the infection. Moreover, 20-28% of the patients have persistent impaired sense of taste and smell, which is also a frequently reported sequelae after infection with COVID-19. Previous studies show that loss of the sense of taste and smell is associated with a decline in quality of life. Olfactory training has been shown to be effective in other patient groups, while in olfactory dysfunction in COVID-19 there is not yet evidence on the long term effect of olfactory training and whether it can improve quality of life. Aim: The primary aim is to investigate whether systematic olfactory training with essential oils to improve impaired sense of taste and smell following COVID-19 can improve patients' quality of life. The secondary aim is to investigate the effect of olfactory training. Method: Patients with anosmia or hyposmia following COVID-19 will be randomized to the intervention or control group. The intervention group received essential oils with scents of orange, lavender, clove, and peppermint. The control group received the four same containers, but with fragrance-free oils. Both groups will be instructed to do olfactory training with each of the oils for 30 s in the morning and evening for 3 months. Subjective olfactory status and quality of life will be evaluated with Taste and Smell Tool for Evaluation at baseline and at 3-month follow-up. The effect of olfactory training will be evaluated with Sniffin' Sticks. Results and Conclusion: The study has not yet been completed.

The nanocomposites designs of phytomolecules from medicinal and aromatic plants: promising anticancer-antiviral applications.

BACKGROUND: Nowadays, researchers are moving toward a herbal approach to cancer treatment because of the harmful effects of synthetic anti-tumor drugs. The evaluation of active compounds with plant origin may help in the remedy of human illnesses in the future. These active compounds have direct or indirect curative efficacies on difficult to cure diseases such as cancer. Investigation of nanoforms of these active compounds is one of the curious topics of the scientific community. MAIN BODY: Saffron and its components obtained from Crocus sativa, essential oils obtained from lavender, Syzygium aromaticum called cloves and Beta vulgaris are known for their anticancer effects. Nano-drugs are designed to increase the anticancer activity of plant-derived drugs. Herbal extracts operate very great in the production of nanoparticles. The aim is to ensure that only the nano-drug is delivered to the tumor site. Furthermore, nanoparticles have hazardous effects when analyzed at elevated doses, but this issue can be doped together with plant extracts. SHORT CONCLUSIONS: The nanocomposites (graphene oxide, solid lipid nano and nanoemulsion) of phytomolecules obtained from saffron, clove, lavender and red beet may be effective in minimizing these toxic effects. In the near future, detecting the anticancer molecular mechanisms of these naturally derived compounds and nanocomposites could contribute to further cancer research. Apart from these, these compounds and its nanocomposites could have antiviral effects against today's threat covid-19 virus. Consequently, more promising anticancer and antiviral agents would be discovered.

Kefir samples with volatile oils retained their sensory and textural characteristics for a longer time during storage. (4) Conclusions: The volatile oils added to kefir positively influenced the sensory and textural characteristics of the finished product.

What Is New in Occupational Allergic Contact Dermatitis in the Year of the COVID Pandemic?

PURPOSE OF REVIEW: This article aims to summarize some recent trends in occupational allergic contact dermatitis (ACD), including dermatitis related to pandemic-level personal protective equipment in healthcare workers, hazards patients may experience when working from home, and occupational perspectives on the recent American Contact Dermatitis Society (ACDS) allergens of the year and ACDS Core Allergen Series updates. RECENT FINDINGS: Recent ACDS Allergens of the Year may be particularly relevant to healthcare workers, including isobornyl acrylate, which is present in glucose sensors and propylene glycol present in hand cleansers and disinfectants. Lavender, limonene, and linalool, all of which are new additions to the ACDS Core Allergen Series, have been reported as causes for occupational ACD in massage therapists and aromatherapists. Isothiazolinone allergy continues to rise in both consumer and occupational settings. Finally, the COVID-19 pandemic has resulted in a wave of occupational ACD in healthcare workers to personal protective equipment, and revealed new potential allergens for individuals working from home. Occupational allergic contact dermatitis continues to exert a significant occupational disease burden. Remaining aware of the current trends in allergens may allow for earlier recognition, diagnosis, and treatment, subsequently helping our patients to work in healthier and safer environments.
