The Relaxation Effect of Music and Natural Sounds

With the spread of the coronavirus infection in Japan, the suicide rate has increased. So, we thought that we want to take care of people's mental health by using music. In previous studies, they showed that music included 1/f frequency influence the state of mind relaxing. On the other hand, there are reports that the natural sounds induce the state of relaxing. In this study, we investigated whether the reminiscence of scenes by natural sounds can work on the central nervous system and bring about a relaxing effect, and whether a synergistic effect can be observed by working together with the autonomic nervous system. Headphones and a questionnaire were also used. Twelve young male and female were recruited as subjects. The results showed that most of the subjects had a good impression of music, nature sounds and their mixtures. The results for music and nature sounds were mixed, but most of the subjects had a good impression of the blended sounds. The effect on relaxation, as measured by the questionnaire, was better after listening to the music than before in all conditions. In all conditions, there was a greater improvement in relaxation after listening to the music than before, and the degree of improvement was as follows: mixture > nature sounds > music. Although there was no statistical superiority, it was possible to show this trend. This suggests that there may be a synergistic effect of mixing music, which affects the autonomic nervous system, with nature sounds, which affect the central nervous system. © 2022 IEEE.

Resilience Control Room Operator During Pandemic Covid-19

The control room acts as a central nervous system facility. This is where important decisions, using complex systems, are made every day. The actions of control room operators have a direct impact on uptime, production yields, quality, and industrial plant safety. In addition, long working hours per shift result in fatigue, irregularity of circadian rhythms and sleep cycles, and decreased cognitive performance at the end of day and night shifts. Fatigue causes decreased alertness, attention span, poor memory, and concentration and affect other mental factors. ADNOC Gas Processing established Fatigue Risk Management Taskforce (FRMT) to adapt practices to the specific conditions and create a safer working environment, leading to happier and healthier employees and an overall community. In industries that run continuous and heavy-duty plants such as Oil, gas, and petrochemical, shift work ensures production flow. After the outbreak of Covid-19, business needs to adapt quickly so that their activities can run. The finding suggests that the workers' cognitive performance is reduced, shown by the increase of triggered alarm by the average of 14.39% higher than before the outbreak of Covid-19. However, with the ability to adapt and implement control and monitoring measures, the number of alarm rate gradually decreased. The study framework was proven to be a valuable tool that decision-makers can use, especially to measure the performance of control room workers and their psychological fatigue affected by the Covid-19 pandemic. © Copyright 2021, Society of Petroleum Engineers

Finger Induced Auto-Thermogenesis

Heat through hand-clasping with a specific finger pose (HCFP) is a tool for eliciting innate immune system response to control the SARs-CoV-2 virus. Fifteen male subjects participate in a study in which ECG and axillary temperature are measured, with and without HCFP. The heat induction is derived from temperature slope and we studied its effect on heart rate variability (HRV) and resting metabolic rate (RMR). Compared to the normal state, the average axillary temperature slope increases by 11.5% along with a significant increase in resting metabolic rate (RMR) (p<0.05) respectively. HRV enhances through an increase in SDRR and RMSSD by 23.75 and 24.44%, respectively. The Augmented-LFHF ratio reduces significantly (p<0.001). HCFP induces body-heat mediated by parasympathetic nervous system (PSNS) dominance with minimal changes in body temperature due to thermoregulation. © 2021 ECBIOS 2021. All rights reserved.

Shoulder Pain in COVID-19 Survivors Following Mechanical Ventilation.

COVID-19 has caused a certain proportion of patients to be hospitalized in intensive care units (ICU) and may cause musculoskeletal and neurological deficits following intubation and mechanical ventilation. The aim of this study was to quantify and describe the presence of shoulder pain in patients released from hospitals after suffering COVID-19. Patients with positive Apley tests were sent to a physiatrist for a clinical evaluation, ultrasound and electromyography (EMG). This evaluation was completed with a pain scale, joint range and shoulder muscle strength evaluations. Of the one-hundred-sixteen patients, seventy eight entered the respiratory rehabilitation program. Twenty patients were sent to the multidisciplinary shoulder team for positive Apley scratch tests. Of these twenty patients, one had only an EMG, ten had only ultrasounds, seven had an EMG and ultrasound and two did not need complementary tests. The twenty patients were sent to the physical therapist, with all presenting pain and diminished joint range and muscle strength in the affected shoulder. In this context, shoulder pain could be associated with the prone position in the ICU. We suggest time control and position change for patients on mechanical ventilation in a prone position with COVID-19.

Neurological manifestations of coronavirus infections: role of angiotensin-converting enzyme 2 in COVID-19.

AIM OF THE STUDY: In December 2019, a highly pathogenic coronavirus called SARS-CoV-2 (formerly identified as 2019-nCoV) appeared in Wuhan, China, and has since been spreading rapidly around the world. we reviewed the neurological manifestations of this infection and the potential of ACE2 in the nervous system. MATERIALS AND METHODS: Six databases (Medline, Scopus, Embase, Web of Science, WHO, and google scholar) were searched and screened by the authors for having appropriate information about covid-19. Finally, 72 studies were identified, summarized and reviewed. RESULT: The most specific manifestation of SARS-CoV-2 patients is pulmonary distress, and several patients admitted to intensive care units were not able to breathe spontaneously. In addition, the SARS-CoV-2 outbreak has a significant effect on nervous systems and may even lead to serious neurological damage. The neuroinvasive pathobiology is still not fully elucidated and thus the effect of CoV infections on the nervous system needs to be explored. The spike protein of the virus and the angiotensin-converting enzyme 2 (ACE2) lead to the presence of both SARS-CoV and SARS-CoV-2 in the cells and, subsequently, decreased ACE2 expression. CONCLUSION: The therapeutic possibilities of ACE2 antibody, ACE2-derived peptides, and small molecule blockers of ACE2 include a receptor-binding domain blocking approach. Hence, future studies of ACE2 may be very helpful in discovering a therapy for SARS-CoV-2.
