ABSTRACT
Objective: In the twenty-first century, despite the development in infection management, and improvement of vaccines and therapeutic agents in the field of health, new viral outbreaks that can still be fatal in humans and animals are emerging. The infection of zoonosis COVID-19 from bat origin, the intermediate host of which is still being unclear, has appeared in people who visited animal bazaar in December 2019, in Wuhan, China. The World Health Organization declared this infection a pandemic in February 2020. Millions of people have been affected by this pandemic. The fight against the pandemic has had a great economic cost and continues to do so. Even people have changed their lifestyle. In this context, there have been concerns about companion animals with COVID-19 transmission, from human to animal or animal to human. The purpose of this review was to examine the studies on the presence and transmission of COVID-19 in companion animals such as cats, dogs, hamsters and horses. Result and Discussion: It has been reported in studies that most of the companion animals (cat, dog and hamster) were susceptible to SARS-CoV-2, and humans could be a source of infection for them. However, the potential role of companion animals in transmission to humans is not fully known. It is clear from this pandemic that the necessity of epidemiological investigation of infectious agents, especially zoonotic ones, in one health concept has emerged once again.Copyright © 2022 University of Ankara.

ABSTRACT
Objective: to study the causes and predictors of mental disorders during the COVID-19 epidemic in those who turned to psychiatrist for the first time, as well as in patients with already diagnosed mental illness. Patients and methods. We examined 100 patients who turned to a psychiatrist due to a deterioration in their mental state during the pandemic, 50 patients were newly diagnosed (Group 1) and 50 with previously diagnosed mental disorders (Group 2). The study was carried out by a clinical method using a specially designed map, followed by statistical processing of the obtained data. Results and discussion. Mental disorders caused by the COVID-19 pandemic more often occurred at a young age, in patients with higher and secondary specialized education, and in single patients. In the 1st group, as a result of exposure to psychogenic factors (the influence of the media, quarantine, economic changes), anxiety (36.8%) and depressive (21.1%) disorders occurred more often, and after the coronavirus infection, depressive disorders were in the first place (54.2%). The 2nd group mostly included patients with endogenous disorders (bipolar affective disorder - 24%, recurrent depressive disorder - 20%, schizophrenia - 20%), which were exacerbated more often as a result of COVID-19, to a lesser extent - psychogenic (experiences associated with a change in material status and illness of relatives). Obsessive-compulsive disorder, generalized anxiety disorder, somatoform disorders have been associated with epidemic factors. Conclusion. The results obtained indicate that there are differences between the mental disorders that first appeared during the pandemic and the exacerbations of the condition in mentally ill patients, which relate to the predictors, causes and clinical manifestations of these disorders.Copyright © 2022 Ima-Press Publishing House.

ABSTRACT
Objective: To study the clinical characteristics of diabetes mellitus with Coronavirus disease 2019 (COVID-19) and explore the possible mechanism of diabetes predisposition. Method(s): A single center, retrospective and observational study was used to collect 48 inpatients diagnosed with COVID-19 who were admitted to the first ward of the third department of infection, Raytheon hospital, Wuhan from February 23, 2020 to March 30, 2020. Demographic data, symptoms, laboratory tests, comorbidities, treatments and clinical outcomes have been collected. The patients were divided into non-diabetic group and diabetic group according to the combination of diabetes. The clinical data and laboratory test results of the two groups were observed, and the t test, non-parametric test and Chi square test were used for comparison. Result(s): All the 5 patients with COVID-19 diabetes mellitus had fever and respiratory symptoms, chest CT was consistent with typical COVID-19 imaging features, and novel coronavirus nucleic acid test results were positive. There were no statistically significant differences in age, gender composition, co-existing diseases, clinical symptoms, clinical typing, disease course and treatment plan between the diabetic group and the non-diabetic group (P>0.05).There was a statistically significant difference in fasting blood glucose between the non-diabetic group and the diabetic group (P<0.05).The difference of fasting blood glucose at discharge from the diabetes group compared with that at admission was also statistically significant (P<0.05).There was no statistically significant difference between the two groups in other laboratory examination indexes (P>0.05). Conclusion(s): COVID-19 patients with diabetes are mainly manifested by fever and respiratory symptoms.Chest CT shows typical COVID-19 imaging features.Copyright © 2020 by the Chinese Medical Association.
ABSTRACT
Atrial fibrillation (AF) is the most frequent form of cardiac arrhythmia in COVID-19 infected patients. The occurrence of AF paroxysms is often associated with the acute period of infection in time. At the same time, the pathophysiological mechanisms of the occurrence of AF associated with COVID-19 remain insufficiently studied. The review considers the available literature data on the influence of factors such as reduced availability of angiotensin-converting enzyme 2 receptors, interaction of the virus with the cluster of differentiation 147 and sialic acid, increased inflammatory signaling, "cytokine storm", direct viral damage to the endothelium, electrolyte and acid-alkaline balance in the acute phase of severe illness and increased sympathetic activity.Copyright © Autors 2023.

ABSTRACT
Arterial thrombosis encountered during sars-cov2 infections is a rare complication with a poor prognosis compared to venous ones. They generally occur in severe and critical clinical forms of covid19 [1,2]. The physiopathology of arterial thrombosis, even if not completely understood highlights hypercoagulability and excessive inflammation as risk factors with a major role of the endothelial lesions in their occurrence. The presence of cardiovascular risk factors in patients infected with covid19 is also discussed as a predisposing factor for arterial thrombosis [2,3]. We report the case of a North African male patient hospitalized for acute respiratory distress syndrome (ARDS) secondary to covid19 pneumonia, complicated by the occurrence of multiple arterial thrombosis of the aorto-iliac axis with the rare finding of two free floating thrombus in the aorta and the right common iliac artery. Clinically, the patient had developed acute bilateral lower limb ischemia and multi-organ failure and the evolution was dramatic with rapid worsening of the patient…s health and eventually his death. Thromboembolic complications are frequent during covid19 infection but the aortic localization is very rare. Its diagnosis is difficult and it has a poor prognosis. Our objective through this case report is to increase knowledge about arterial thromboembolic events while discussing their link to the sars-cov2 viral infection. © 2022
ABSTRACT
Background COVID-19 started in China and has spread throughout the world since December 2019. The pandemic has not only brought the risk of morbidity and mortality from infection but also psychological burden. Objective To find out the psychological impacts of COVID-19 on students from high schools, colleges and universities in Nepal, along with examining the association between socio-demographic and other related variables and level of anxiety in the students. Method This study sampled students from Nepal using convenience sampling and responded to a quantitative questionnaire that included the 7-item Generalized Anxiety Disorder Scale (GAD-7) and other basic information. Finally, 105 respondents were included in the final analysis (100% response rate). Convenient sampling technique was used to gather the sample. Result The results indicated that 18.1% of the respondents were experiencing severe anxiety, 22.9% moderate anxiety, and 25.7% mild anxiety. Moreover, females were more prone to anxiety as compared to males. The results of correlation analysis indicated that economic effects, and delays in academic activities, were positively associated with anxiety symptoms (p < .05). However, social support was negatively correlated with the level of anxiety (p < .001). Conclusion It is recommended that the mental health of students should be monitored during public health emergencies, such as this one. This study examines the psychological impacts of COVID-19 among the college students in Nepal. Copyright © 2020, Kathmandu University. All rights reserved.
ABSTRACT
An organism's survival depends on its ability to adapt to stress. Mitochondria are the cellular integrators of environmental stressors that ultimately translate their responses at the organismal level, and are thus central to the process whereby organisms adapt to their respective environments. Mitochondria produce molecular energy via oxidative phosphorylation that then allows cells to biosynthetically respond and adapt to changes in their environment. Reactive oxygen species (ROS) are by-products of oxidative phosphorylation that can be either beneficial or damaging, depending on the context;ROS are hence both the conveyors of environmental stress as well as cellular "adaptogens”. Mitohormesis refers to the process whereby low levels of oxidative stress spur survival adaptations, whereas excessive levels stymie survival. Low energy and frequency pulsing electromagnetic fields have been recently shown capable of stimulating mitochondrial respiration and ROS production and instilling mitohormetic survival adaptations, similarly to, yet independently of, exercise, opening avenues for the future development of Magnetic Mitohormetic interventions for the improvement of human health. This viewpoint explores the possibilities and nuances of magnetic-based therapies as a form of clinical intervention to non-invasively activate magnetic mitohormesis for the management of chronic diseases. © 2023 Centro Regional de Invest.

ABSTRACT
Background: The COVID- 19 infections are associated with wide range of bacterial and fungal co-infections. They may be associated with various comorbidities. Definite diagnosis requires demonstration of fungi in tissue sections or in culture. Yield of organism in culture is suboptimal. Hence histopathology plays critical role in establishing the diagnosis and provide evidence of tissue invasion. Objective(s): To study the histopathological features of fungal infections in sino nasal, oral and orbital area associated with COVID-19 patients. Material(s) and Method(s): One hundred twenty cases of fungal infections involving sinonasal, oral and orbital area in laboratory confirmed COVID-19 positive patients between June-September 2021 were taken for study. Clinical data was recorded, histopathological examination was done along with periodic acid Schiff stain and culture report was obtained. Result(s): The study included 92(76.6%) males and 28(23.3%) females with age ranging from 13 to 78 years. The tissues included debridement, biopsy and excision specimen. Acute inflammation was seen in 8(6.66%) cases, chronic inflammation in 112(93.33%), granulomas in 25, thrombosis in 14, necrosis in 104, angioinvasion in 13, perineuritis in 10 and bone invasion in 18 cases. Mixed fungal infection was seen in 11cases. Conclusion(s): Histopathology remains the mainstay in diagnosis of invasive fungal infections especially when culture is negative.

ABSTRACT
Objective: Adulthood retroclival hematomas (RCHs) are a rare condition characterized by intracranial bleeding along the posterior aspect of the clivus. There are few reports in the literature that describe these hematomas. There is no agreement on how to treat these hematomas. Methods: An extensive literature review was performed, and the data was classified and analyzed on this topic from January 2000 to January 2022. A systematic review was carried out in accordance with the PRISMA and CARE Guidelines. Results were analyzed and potential clinical links were extracted. Results: Twenty-seven RCHs in adulthood were reported in twenty high-quality articles. 12/27 RCHs in adults were spontaneous. Epidural retroclival hematomas were present in 12/27 patients, while subdural hematomas were present in 13/27 patients. 15 of 22 adult RCHs observed were small in size. Epidural hematomas are typically associated with trauma (9/15 traumatic RCHs), whereas subdural hematomas are more frequently associated with spontaneous bleeding (8/12 spontaneous RCHs). There was one case of hydrocephalus, six cases of cranial nerve palsies (five of which were traumatic), and thirteen cases of intraspinal extension of the hematoma. Seven individuals exhibited craniovertebral instability (100 percent traumatic). Most hematomas were conservatively treated (77.8 percent). 21 hematomas had favorable clinical outcomes. Conclusions: There is a lack of agreement on management protocols for RCHs in adulthood. These hematomas occur almost equally in both the extradural and the subdural spaces, and they are typically small in size. When an RCH occurs in the epidural space, it is more likely to result in cranial nerve palsies and craniospinal instability. Associated craniovertebral anomalies must be thoroughly analyzed in trauma patients. Only patients with a significant mass effect on the brainstem are candidates for surgical hematoma evacuation. It is imperative that future studies on this rare entity adhere to strict publication guidelines.
ABSTRACT
Mucormycosis is a fungal infection which is caused by a rare type of opportunistic fungal pathogen called mucormycetes. It is a serious and potentially fatal fungal infection. A wide range of bacterial and fungal co-infections have been associated with COVID 19. The second wave of COVID 19 showed a sudden surge in mucormycosis. The most commonly observed form was rhino cerebral mucormycosis. Most of the patients had diabetes as a pre-disposing factor and had received steroids, oxygen therapy, biologicals and antibiotics as a part of treatment of COVID 19. COVID 19 in itself favours the growth of mucormycosis owing to the weakened immune system. While the diagnosis of mucormycosis still remains challenging the treatment mainly aims at managing co-morbid condition in high-risk group, anti-fungal therapy using Amphotericin B and azoles and surgical debridement. In this article, we analysed, 71, histopathologically confirmed cases of mucormycosis associated with COVID 19 admitted and studied their clinical profile and risk factors associated with it.
ABSTRACT
Background: The COVID-19 pandemic is badly affecting more than 2 million population of 213 countries and has caused 1,952,976 deaths till January 12, 2020. India has also suffered a great loss in terms of economy and people. Furthermore, owing to the complete lockdown enforced in India, restricting humanitarian movement also affected day-To-day life of Indians with a huge impact. Objectives: The present clinical trial was carried out to evaluate the impact of the COVID-19 pandemic on private practitioners. Furthermore, changes in their practice pattern were evaluated along with the perspective of their health, role, and response to the pandemic. Materials and Methods: The study includes a total of 120 health-care professionals of either gender. The stress and mental health of the participants was assessed using Depression Anxiety Stress Scale-21 in English format, also included the questions related to the demographic characteristics, use of technologies for providing virtual health care, changes in the working during the pandemic, and an opinion of their experiences during that period. The data collected were subjected to the analysis and were kept confidential and anonymous. Results: 16.6% of participants preferred virtual consultation before the pandemic in contrast to 83.3% during the pandemic. The most preferred method remained the phone call by 15.8% (n = 19) patients. Depression was seen severely in 35% of study participants (n = 42) and 13.3% of participants extremely severe depression was seen (n = 16). Severe and extremely severe anxiety was noticed in 31.66% (=38) and 15% (18) study participants respectively, whereas severe and extremely severe stress was found in 30% (n = 36), and 12.5% (n = 15) private practitioners. The most common factor that can be considered responsible for compromised mental health in private practitioners was the possibility of infecting the society seen in 59.1% (n = 71) participants. Conclusion: During the pandemic breakout, private practitioners suffered a great challenge both financially and mentally, especially during the lockdown. Furthermore, a significant increase was seen in the virtual consultation methods during the pandemic breakout.
ABSTRACT
The mitochondrial respiratory chain is the main site of reactive oxygen species (ROS) production in the cell. Although mitochondria possess a powerful antioxidant system, an excess of ROS cannot be completely neutralized and cumulative oxidative damage may lead to decreasing mitochondrial efficiency in energy production, as well as an increasing ROS excess, which is known to cause a critical imbalance in antioxidant/oxidant mechanisms and a "vicious circle" in mitochondrial injury. Due to insufficient energy production, chronic exposure to ROS overproduction consequently leads to the oxidative damage of life-important biomolecules, including nucleic acids, proteins, lipids, and amino acids, among others. Different forms of mitochondrial dysfunction (mitochondriopathies) may affect the brain, heart, peripheral nervous and endocrine systems, eyes, ears, gut, and kidney, among other organs. Consequently, mitochondriopathies have been proposed as an attractive diagnostic target to be investigated in any patient with unexplained progressive multisystem disorder. This review article highlights the pathomechanisms of mitochondriopathies, details advanced analytical tools, and suggests predictive approaches, targeted prevention and personalization of medical services as instrumental for the overall management of mitochondriopathy-related cascading pathologies.

Verbal communication is one of the most sophisticated human motor skills reflecting both-the mental and physical health of an individual. Voice parameters and quality changes are usually secondary towards functional and/or structural laryngological alterations under specific systemic processes, syndrome and pathologies. These include but are not restricted to dry mouth and Sicca syndromes, body dehydration, hormonal alterations linked to pubertal, menopausal, and andropausal status, respiratory disorders, gastrointestinal reflux, autoimmune diseases, endocrinologic disorders, underweight versus overweight and obesity, and diabetes mellitus. On the other hand, it is well-established that stress overload is a significant risk factor of cascading pathologies, including but not restricted to neurodegenerative and psychiatric disorders, diabetes mellitus, cardiovascular disease, stroke, and cancers. Our current study revealed voice perturbations under the stress overload as a potentially useful biomarker to identify individuals in suboptimal health conditions who might be strongly predisposed to associated pathologies. Contextually, extended surveys applied in the population might be useful to identify, for example, persons at high risk for respiratory complications under pandemic conditions such as COVID-19. Symptoms of dry mouth syndrome, disturbed microcirculation, altered sense regulation, shifted circadian rhythm, and low BMI were positively associated with voice perturbations under the stress overload. Their functional interrelationships and relevance for cascading associated pathologies are presented in the article. Automated analysis of voice recordings via artificial intelligence (AI) has a potential to derive digital biomarkers. Further, predictive machine learning models should be developed that allows for detecting a suboptimal health condition based on voice recordings, ideally in an automated manner using derived digital biomarkers. Follow-up stratification and monitoring of individuals in suboptimal health conditions are recommended using disease-specific cell-free nucleic acids (ccfDNA, ctDNA, mtDNA, miRNA) combined with metabolic patterns detected in body fluids. Application of the cost-effective targeted prevention within the phase of reversible health damage is recommended based on the individualised patient profiling.
