New onset of loss of smell or taste in household contacts of home-isolated SARS-CoV-2-positive subjects

Purpose: To estimate the prevalence of smell or taste impairment in household contacts of mildly symptomatic home-isolated SARS-CoV-2-positive patients. Methods: Cross-sectional study based on ad hoc questions. Results: Of 214 mildly symptomatic COVID-19 patients managed at home under self-isolation, 179 reported to have at least one household contact, with the total number of no study participants contacts being 296. Among 175 household contacts not tested for SARS-CoV-2 infection, 67 (38.3%) had SARS-CoV-2 compatible symptoms, 39 (22.3%) had loss of smell or taste with 7 (4.0%) having loss of smell or taste in the absence of other symptoms. The prevalence of smell or taste impairment was 1.5% in patients tested negative compared to 63.0% of those tested positive for SARS-CoV-2 (p < 0.001). Conclusion: Smell or taste impairment are quite common in not-tested household contacts of mildly symptomatic home-isolated SARS-CoV-2-positive patients. This should be taken into account when estimating the burden of loss of sense of smell and taste during COVID-19 pandemic, and further highlights the value of loss of sense of smell and taste as a marker of infection

Therapeutical innovations and medical responsibility: What's new in oto-laryngology

On one hand the incessant and constant technological and instrumental progress in the medical fieldhas allowed to increase knowledge and to reach new objectives. On the other hand, however, it has also raised the risk linked to professional responsibility, regarding informed consent and law 24/2017 of the Italian Republic, better known as Gelli Bianco. In this work an analysis of relevant literature will be presented, followed by a study on the role of new devices on responsibility profiles in otolaryngology. According to the analysis of the Italian law and considering the weaknesses ofthe above mentioned guidelines, pending legal administrative clarifications, we believe an operational protocol can be proposed in case of application of therapeutical innovations, especially about experimental introductions. Consequently, in our opinion, the risk of incrimination persists in case of use of innovative procedures in the absence of a formal shared opinion expressed in guidelines or in good practices, which still need a satisfactory definition

The secretory senescence in otorhinolaryngology: Principles of treatment

Atrophy or hypofunction of the salivary gland because of aging, radiotherapy or disease causes hyposalivation and impairs the quality of life of patients by compromising mastication, swallowing and speech and by leading to a loss of taste. Moreover, hyposalivation exacerbates dental caries and induces periodontal disease, and oral candidiasis. Currently, no satisfactory therapies have been established to solve salivary hypofunction. Current treatment options for atrophy or hypofunction of the salivary glands in clinical practice are only symptomatic and include saliva substitutes and parasympathetic agonists, such as pilocarpine, to stimulate salivary flow. However, parasympathomimetics have systemic side effects, so different treatment options are necessary, and research has recently focused on this. The main strategies that have been proposed to restore salivary gland atrophy and hypofunction are gene therapy by gene activation/silencing during stem cell differentiation and by the use of viral vectors, such as adenoviruses; cell-based therapy with salivary gland cells, stem cells and non-salivary gland and/ or non-epithelial cells to regenerate damaged salivary gland cells; replacement with tissue bioengineering in which organoids from pluripotent stem cells are used in the development of organ replacement regenerative therapy. Remarkable progression in this research field has been made in the last decade, but a definitive therapy for salivary gland hypofunction has not been developed due to intrinsic challenges that come with each approach. However, with research efforts in the future, a range of precision medicine therapies may become available individualized to each patient

The European Association for the Study of Obesity (EASO) Endorses the Milan Charter on Urban Obesity

The Milan Charter on Urban Obesity highlights the challenges of urban environments as a battleground for human health, as cities are often organized to subvert public health goals, and promote rather than prevent the development of obesity and consequent non-communicable diseases. The Charter articulates ten principles which detail actions and strategies through which general practitioners, diverse medical specialists, related healthcare professionals, administrators and healthcare practice managers, policy actors - within health systems and at a national level - along with experts across disciplines, and citizens, can work in cooperation to meet this challenge and improve publichealth. The Charter urges the adoption of decisions that deliver the following: (i) policies which enable our cities to become healthier and less obesogenic, more supportive of well-being and less health-disruptive in general, and (ii) policies that fully support primary prevention strategies, that address social stigma, and that ensure fair access to treatment for people living with obesity. The Milan Charter on Urban Obesity aims to raise awareness of our shared responsibility for the health of all citizens, and focuses on addressing the health of people living with obesity - not only as a challenge in its own right, but a gateway to other major non-communicable diseases, including cardiovascular diseases, type 2 diabetes, and some cancers

Re‐Thinking the Environment, Cities, and Living Spaces for Public Health Purposes, According with the COVID‐19 Lesson: The LVII Erice Charter

Urban planning is a key tool to promote health in cities. The COVID-19 emergency accelerated several social, environmental, and digital challenges, stressing the importance of some issues regarding housing, urban mobility, green areas, and health service networks, urban health policies, and actions. These issues were the subject of an intensive residential course (the 57th) held in Erice, Sicily, in June 2021 in the “International School of Epidemiology and Preventive Medicine G. D’Alessandro”, and the main findings are described here. Methods. Lectures presented the topics, subsequently developed them, and argued them in parallel practical sessions using the World Café technique, since it is well suited for the interaction of participants and the involvement of groups. Results. The World Café provides new insights into how to improve the livability and health of urban spaces, and a set of strategies and actions were proposed for each topic. Discussion and Conclusions. All attendees agreed on the importance of participation in the planning processes, but also on the need for strong political support to ensure the resources needed and a full integration of health with other local policies. A multidisciplinary approach to developing systemic operational capacities and health literacy is considered pivotal to raising awareness and participation

Analysis of electrical power data for condition monitoring of a small wind turbine

This paper is a postprint of a paper submitted to and accepted for publication in IET Renewable Power Generation and is subject to Institution of Engineering and Technology Copyright. The copy of record is available at IET Digital Library.Certain parts of a wind turbine, for example, the gearbox require significant time and heavy lifting equipment in the event of catastrophic failure necessitating replacement. Continuous condition monitoring has the potential to catch problems early, enable scheduled preventative maintenance and thereby reduce turbine downtime, reduce the number of site visits and prevent secondary damage. Accelerometers applied to mechanical components of the drive train are traditionally used for condition monitoring but require their own data acquisition system and analysis software. In contrast, the electrical current and voltage are continuously measured and could also be used for condition monitoring more cheaply. An experimental data acquisition system has been installed on a small (25kW) onshore turbine in Leicestershire, UK to compare three-phase currents and voltages on the stator windings with six accelerometer signals. Data have been recorded before and after a gearbox failure and replacement. Data were analysed using both Fourier Transform and Morlet Continuous Wavelet Transform methods. Results show that the stator voltages show the same radial and axial mode vibration frequencies as the accelerometers and could therefore be used for condition monitoring. Furthermore, the stator currents show torsional modes of vibration not picked up by the accelerometers

A new histological method to study oral soft tissue penetrability to iodine and optimize oral use of iodine solutions

The aim of this work is to establish a histological method to fix iodine inside slides of treated oral mucosa more permanently in order to allow section counterstaining and facilitate improved clinical and experimental studies on iodine penetration. Transforming iodine into a stable histological formation inside tissues is particularly useful for histological analysis of clinical and experimental iodine treatments. In the field of oncology, this method can be applied to povidone-iodine-treated (human or animal) mucosa or skin, to organs treated with iodine tincture or Lugol’s solution, to oral lesion detection and to mucogingival junction identification
