COVID-19 PANDEMIA AND PUBLIC AND GLOBAL MENTAL HEALTH FROM THE PERSPECTIVE OF GLOBAL HEALTH SECURITY
The Coronavirus disease 2019 (COVID-19) pandemic emerged in Wuhan, China and has spread all over the world and has caused huge threats to health and lives. It has affected different frontiers of lives and induced many psychiatric individual and collective problems such as panic, anxiety, depression, post-traumatic stress disorders, suspiciousness, infodemia, cacophony, xenophobia, racisms, etc. The COVID-19 outbreak has induced public and global mental health crisis as well as a huge psychosocial experiment. Psychiatry and other mental health sciences can play very useful role in supporting the well-being of COVID-19 patients and their families, healthcare personnel and the society. For successful fighting with present and future pandemics we have to learn more about psychiatric and psychological aspects of COVID-19 from the perspectives of public and global mental health
PSYCHIATRY FOR BETTER WORLD: COVID-19 AND BLAME GAMES PEOPLE PLAY FROM PUBLIC AND GLOBAL MENTAL HEALTH PERSPECTIVE
Blame games tend to follow crisis, be they at local, national or international level related to political, financial or health issues. COVID-19 crisis from the very beginning has been followed by divisive and disruptive psychosocial and political blame games. Active or passive blaming is an inherent feature of human beings in order to shift responsibilities onto others, single out a culprit, find a scapegoat and pinpoint a target. Finger pointing, blame games and scapegoating are associated with creation of binaries that identify agency as good or bad, right or wrong, moral or immoral. The scapegoat is expectedly always bad, wrong and immoral, commonly black evil. The detrimental effects of the COVID-19 blame games are seen in a lack of cohesion and coherence in the anti-COVID-19 solving strategies. Fighting the COVID 19 crisis all countries and nations need to join efforts on defeating it and to shift from a destructive blaming and zero-sum type of thinking to a much more creative, systemic and humanistic type. Effective response to COVID-19 is related to sowing the seeds for humanistic self and empathic civilization, rather than blaming, scapegoating and xenophobia
COVID-19 INFODEMIC AND PUBLIC TRUST FROM THE PERSPECTIVE OF PUBLIC AND GLOBAL MENTAL HEALTH
Crisis usually involves participants who trust and distrust each other, commonly in the same time. COVID-19 infodemic induced confidence crisis and distrust in authorities, science communities, governments and institutions can lead to harmful health behaviors and ill mental health and become a serious threat to public and global mental health as another kind of virus. Distrust mentality, conspiracy thinking and blame games may have detrimental effects not just on the individual level, but on the level of the whole groups, communities and global world. Public distrust and mistrust are related to the crisis in the domain of social and political relations, not only on the same country level, but also between different countries at regional or global level. Dynamics between public trust and mental health is a complex and bidirectional, ill mental health is causing and enhancing the inclination to confidence crisis, distrust, conspiracy theories and blame games and vice versa confidence crisis, distrust, conspiracy thinking and blame games are leading to ill mental health. It is important to have a holistic transdisciplinary integrative understanding of these dynamics and science-based treatment and prevention
PSYCHIATRY, SCIENCE AND RELIGION AS PARTNERS IN PROMOTION OF PUBLIC AND GLOBAL MENTAL HEALTH THROUGH SPIRITUALITY
Uteropexy in Sheep as Potential Method for Prevention of Uterine Torsion
Background: Uterine torsion is one of many causes of dystocia in sheep. Failure in performing of wright-time diagnostic procedures and treatment by certain obstetric procedures, can result with death of both fetus and ewe. There is sufficient knowledge about risk factors which could contribute to the occurrence of uterine torsion in sheep, but there is insufficient knowledge about measures for prevention of uterine torsion. The aim of this study was to evaluate the effects of performing incorporative uteropexy as potential method for prevention of uterine torsion.
Cases: This research was part of the experimental research of changes in the anterior presentation in sheep fetuses due to their ventro-sacral position in the 2nd half of gestation. At the same sheep farm where afore mentioned research was conducted, the farmer has reported the death of 3 pregnant ewes. In all of 3 animals, torsion of the uterus was diagnosed by patho-anatomical examination. This study was conducted on 6 ewes. All of the animals were in the period around the 100th day of pregnancy at the time of clinical examination. The exact day of pregnancy was not determinated because of free mating in the herd. Confirmation of pregnancy in all of 6 ewes was performed by ultrasound examination. Uniparous pregnancy was found in all of 6 ewes. The entire surgical procedures were performed in the field conditions. Laparotomy was performed in the animals positioned in the left lateral recumbency. Surgical procedure of incorporative uteropexy was performed during the closure of muscle layers of abdominal wall. In need for experimental research of changes in the anterior presentation in sheep fetuses due to their ventro-sacral position in the second half of gestation, 14 days after surgical procedures were conducted, all of sheep were positioned by assistants into a sitting position so that their trunks were vertical to the ground and kept in that position for 2 min. Ultrasound examination of surgical place of uteropexy confirmed that, in all of animals, uteruses were in place of surgical procedures. All of 6 ewes included in this study lambed naturally. One of 6 sheep was sent for economic exploitation on the 14th day after lambing. At the slaughter line, the abdominal wall was evaluated at the site where the incorporative uteropexy was performed. Patho-anatomical examination revealed tissue adhesions at the junction of the uterine horn with the abdominal wall.
Discussion: Postsurgical tissue adhesions develop during normal healing process of tissue. According to our knowledge, previous studies do not mention effective measures that could contribute to the prevention of uterine torsion in sheep, but attention is focused on prompt diagnosis and treatment of the disease. According to the results of this study, postsurgical tissue adhesions were developed and confirmed by patho-anatomical examination in 1 sheep. Other 5 sheep were not economically exploited or sacrificed, and no studies were performed to establish the presence of postsurgical tissue adhesions. In conclusion, it could be said that incorporative uteropexy could be considered as preventive procedure in order to avoid the development of uterine torsion in ewes which have shown a history of this pathology, but also in ewes with identified risk factors for the disease. In future studies, it is necessary to identify more parameters which will contribute to identification of sheep which have high risk factors to obtain the torsion of uterus. Also, it is necessary to use non-invasive methods of clinical diagnostics, primary ultrasound diagnostic, to evaluate the area of incorporative uteropexy in order to assess newly formed tissue adhesions as well as to assess the vitality of fetus. It is necessary to follow the lambing process of ewes with incorporated uterus, and to provide medical assistance to the animals if complications occur during the lambing time.

The effects of valsartan on cardiac function and pro-oxidative parameters in the streptozotocin-induced diabetic rat heart
© 2020, University of Kragujevac, Faculty of Science. All rights reserved. Diabetes mellitus is a major risk factor for cardiovascular diseases, while cardiovascular diseases are a leading cause of morbidity and mortality worldwide. The renin–angiotensin– aldosterone system controls renal, cardiovascular, adrenal function and regulates fluid and electrolyte balance as well as blood pressure. Because of his role, inhibition of renin-angiotensin-aldosteron system is another therapy approach that reduces the risk of diabetes and cardiovascular disease. In this study, our goal was to evaluate effect of valsartan,as inhibitor of angiotensin II receptor type 1, on cardiac tissue and function, with focus on cardiodynamic and oxidative stress. The present study was carried out on 20 adult male Wistar albino rats (8 week old and with body masses of 180-200 g). Rats were divided randomly into 2 groups (10 animals per group). Healthy animals treated with 1 μM of valsartan and streptozotocin-induced diabetic animals perfused with 1 μM of valsartan 4 weeks after the induction of diabetes. Our results demonstrated that acute application of valsartan has different effect on cardiodynamics in rat heart of diabetic and healthy animals but did not improve cardiac function in hy-perglycemia-induced changes. A challenge for further investi-gations are studies with chronic or acute administration, alone or in combination with other angiotensin-converting-enzyme inhibitor in various models of diabetes
The effects of direct red bull administration to isolated hearts of trained and untrained rats who regularly consumed or did not consume energy drink: Focus on cardiodynamics and oxidative stress
Energy drinks (EDs) contain caffeine and other active ingredients which affect cardiovascular system. The aims of this study were to examine direct effects of Red Bull (RB) on cardiodynamics and oxidative stress in isolated hearts of rats. The rats were divided into four groups: Untrained rats who never consumed ED (dEDUT); untrained rats who consumed ED 5 days a week during 4 weeks (ch+dED-UT); rats trained 5 times a week for 4 weeks, but did not consume ED (dED-T); rats trained and consumed ED 5 times a week for 4 weeks (ch+dED-T). After sacrificing, hearts were isolated and perfused according to Langendorff technique. Through the isolated heart of all rats in each group, RB was administered. The parameters of cardiac function were recorded, and the levels of prooxidants were measured in the coronary effluent during coronary autoregulation. Rats in ch+dED-UT group had significantly lower rates of myocardial contraction and relaxation compared to rats in dED-UT group. The same effect was recorded in the dED-T group compared to dED-UT group. The levels of hydrogen peroxide were significantly higher in trained rats. Rats in ch+dED-T group also had significantly higher levels of superoxide anion radical and index of lipid peroxidation, as well as lower levels of nitrites when compared to ch+dED-UT group, while opposite effect was recorded in rats in dED-T group compared to dEDUT group. The RB could have a potentially negative inotropic effect in chronic consumers. Prooxidative effect of RB was most pronounced in trained chronic consumers

Acute effects of nandrolone decanoate on oxidative stress in isolated rat heart
Abuse of anabolic-androgenic steroids (AAS) produces side effects in different tissues, with oxidative stress linked to their pathophysiology, being involved in fibrosis, cellular proliferation, and tumorigenesis. The aim of this study was to examine the acute effects of nandrolone decanoate (ND) on oxidative stress in isolated rat heart. The hearts of male Wistar albino were excised and perfused according to the Langendorff technique at gradually increasing coronary perfusion pressures (40-120 cm H2O). The hearts were perfused with ND at doses of 1, 10 and 100 μM. Oxidative stress markers, including the index of lipid peroxidation (thiobarbituric acid reactive substances (TBARS)), nitric oxide (nitrites; NO2-), the superoxide anion radical (O2-) and hydrogen peroxide (H2O2) were measured in the coronary venous effluent. Our results showed that acute effects of ND do not promote the production of reactive oxygen species (ROS). Our finding pointed out that the highest concentration of ND may even possess some anti-oxidative potential, which should be examined further
