Abstract	Hemiballism/Hemichorea (HH) is a hyperkinetic movement disorder observed mostly after cerebrovascular diseases in elderly patients. Even though the improvement in symptoms would be maintained without treatment, in rare cases, lesioning or DBS (deep brain stimulation) surgery provide a chance on relieving the severe involuntary movements. HH is a more rarely reported entity as a diabetic complication and we encountered very few cases treated with surgical intervention for diabetic HH. A 75-year-old female patient with type-II diabetes mellitus was admitted for left-sided disabling involuntary movement despite being medically treated for six months. A GPi (globus pallidus internus) and thalamic Vim (ventral intermediate) nucleus targeted DBS surgery was performed. Complete resolution was achieved with combined stimulation at 1.7 mA of thalamic Vim nucleus and 2.4 mA of GPi. Combined stimulation of thalamic Vim nucleus and GPi resulted in an effective treatment method for HH secondary to diabetes in our case. Even if the rarity of the cases treated surgically withholds us to come to a certain conclusion, it provides a new option to treat HH to our experience.

Abstract	By improving cracking performance, the use of discrete structural fibers allows to produce high performance concrete pavements with decreased thickness and without conventional reinforcement bars, so employment of them might be considered to enhance the sustainability of concrete pavements. However, the number of studies that examines the overall effectiveness of fibers in concrete pavement mixtures are limited, and this study was conducted to fill this gap in literature. In this scope, the efficiency of fibers (polypropylene and steel) in different concrete pavement mixtures and the effect of using them in varying amounts on the performance of concrete pavements were examined by doing an extensive experimental and numerical study. According to the experimental results, similar strength, stiffness, absorption, and porosity, but higher abrasion resistance and post-cracking performances were obtained for fiber reinforced concrete mixtures. In line with the post-cracking performances obtained for them, 2.2–19.8% and 15.9–27.5% reduction in required thickness values were found for polypropylene and steel fiber reinforced mixtures, respectively. Additionally, varying changes in pavement material costs (from 9.1% to 139.8% increase) and CO₂ emissions (from 12.8% increase to 16.4% decrease) were obtained for FRC mixtures. Observations were found heavily dependent on the type and amount of fibers, as well as properties of concrete matrices. In the paper, several discussions and suggestions were provided to explain the reason and importance of the obtained results, and the authors believe that the paper will be beneficial for the following research studies and design works.

Abstract	Objective: To evaluate autopsy reports of the deaths due to electrocution in terms of body mass index, body surface area, and organ weights with a biophysical perspective. Methods: The retrospective study was conducted in Malatya, Turkiye, and comprised autopsy reports of electrocution cases that were obtained from the local branch of the Council of Forensic Medicine related to the period from 2012 to 2019. Organ weights and ventricular thicknesses were compared in terms of body mass index and body surface area. Electrical marks were also evaluated in detail. Data was analysed using SPSS 18. Results: Of the 45 cases, 36(%) were male and 9(%) were female. The overall mean age was 39±13 years (range: 20-71 years). There were no significant differences in organ weights and ventricular thicknesses in different body mass index groups (p>0.05). The weights of head and heart were significantly different in relation to body surface area (p<0.05), but no significant difference were found for other organs and ventricular thickness (p>0.05). Conclusions: Comparing the organ weights in electrocution autopsies to normal organ weights may help decide the cause of death. During autopsy, electrical marks should be evaluated by considering the characteristics of the electrical current.

Abstract	The purpose of this study is to evaluate the attitudes of healthcare professionals toward the COVID -19 vaccine, which has been introduced to healthcare professionals at the beginning of 2021 and give information to them on the disease and vaccine. This cross-sectional analytical study has been performed by conducting an online survey to the healthcare professionals who work at the healthcare institutions in the province of Samsun in Turkey between December 2020 and January 2021. In addition to sixteen questions about the demographic characteristics, the "Attitudes towards the COVID -19 vaccine" scale has been used. MANOVA test and Spearman rho correlation coefficient were used in analytical examinations. A total of 1426 healthcare professional have been reached. 64.3% of participants were female, 44.1% were nurse/midwife and 66.6% were public employees. Regarding the questions in the sub-dimension of positive attitude, the rate of response of "I agree/I strongly agree" was between 40.6% and 54.6%. Positive attitude mean values differ according to gender, age, institution, presence of children, smoking status, being a relative who died due to COVID -19, and profession (respectively

Abstract	In medicine, ozone therapy is used in many instances. This study aims to understand the knowledge and attitudes of healthcare professionals towards ozone therapy. We conducted a cross-sectional survey in a comprehensive hospital between November 2020 and January 2021. In addition to evaluating the sociodemographic characteristics of the healthcare professionals, we performed evaluations through a data collection form that we prepared based on the literature. A total of 544 people were included in the study. We found ozone therapy to be the fifth-most frequently heard (72.2%) and experienced (2%) application among traditional and complementary medical applications. Of the participants, 20.8% (n = 113) correctly answered the questions regarding the methods of application of ozone therapy. We found that the most common route of administration was intravenous administration, with a rate of 56.5% (n = 307). The number of correct answers received for the questions regarding ozone therapy was related to professional experience, sex, and occupation (P = .035, P < .001, and P < .001, respectively). We determined that the knowledge and attitudes of healthcare professionals towards ozone therapy are not satisfactory.

Abstract	The COVID-19 pandemic severely impacted residential care delivery all around the world. This study investigates the current scheduling methods in residential care facilities in order to enhance them for pandemic conditions. We first define the basic problem that addresses decisions associated with the assignment and scheduling of staff members, who perform a set of tasks required by residents during a planning horizon. This problem includes the minimization of costs associated with the salary of part-time staff members, total overtime, and violations of service time windows. Subsequently, we adapt the basic problem to pandemic conditions by considering the impacts of communal spaces (e.g., shared rooms) and a cohorting policy (classification of residents based on their risk of infection) on the spread of infectious diseases. We introduce a new objective function that minimizes the number of distinct staff members serving each room of residents. Likewise, we propose a new objective function for the cohorting policy that aims to minimize the number of distinct cohorts served by each staff member. A new constraint is incorporated that forces staff members to serve only one cohort within a shift. We present a population-based heuristic algorithm to solve this problem. Through a comparison with two benchmark solution approaches (a mathematical programme and a non-dominated archiving ant colony optimization algorithm), the superiority of the heuristic algorithm is shown regarding solution quality and CPU time. Finally, we conduct numerical analyses to present managerial implications.

Abstract	Apitherapy is the use of honey bee products for health and it has been used for similar purposes for a very long time by the public. These products have examples of healing affecting whole body systems. The approach and education of apitherapy in medical schools are inadequate. In this study, the level of knowledge and opinions about apitherapy were investigated in junior and senior students at the medical faculty. A questionnaire about the knowledge and opinions on apitherapy was applied to the students who were determined by randomization in term 1 (n = 100) and 6 (n = 100). Gender distribution within and between terms was almost equal. Apitherapy was the second most commonly known method of complementary medicine in term 1 (55%) and the sixth in term 6 (49%). Honey was the most commonly experienced product in both terms, (1: 69% and 6: 64%) and term 1 students tried all products more often except for propolis. The vast majority of students in both terms did not know the action mechanisms of bee pollen, propolis and bee poison. This study demonstrated that knowledge and experience of apitherapy among the future’s doctors were limited. Placing apitherapy in the curriculum and increasing the number of apitherapist teaching members will increase their tendency to use apitherapy.

Abstract	Aims: It is aimed to investigate the disease processes and drug combinations in patients who received favipiravir treatment. Methods: This cross-sectional, analytical and retrospective study included all patients aged ≥18 years (n = 502) who were hospitalised in Samsun, Turkey, for COVID-19 and were given favipiravir from the date between 25 March 2020 and 3 June 2020. Results: In total, 58.6% (n = 294) of the patients were male and 24.5% (n = 123) were between the ages of 71 and 80 years. During the first case process, the mortality rate was 19.9%, whereas the rate of those who were discharged as is/followed up at home for 14 days was 37.3%. During the second case process, the mortality rate was 6.2%, and the rate of those who was discharged as is/followed up at home for 14 days was 65.6%. The mean length of hospital stay was 10.61 ± 8.17 days for the first and 7.97 ± 4.16 days for the second hospitalisation; this difference was significant. Mortality risk of those who used Tocilizumab or vitamin C beside Favipiravir was higher than those who did not. The length of hospital stay was higher in patients using tocilizumab than in those who did not (P < .001). Conclusion: Administration of favipiravir later in the course of the disease makes it difficult to achieve the true efficacy expected from the drug and also makes it difficult for other combination drugs to contribute to survival. Favipiravir may also be effective in case of recurrence.

Abstract	Introduction and objectives: We aimed to assess the outcomes of patients with trigeminal neuralgia (TGN) who underwent Gamma Knife radiosurgery (GKRS). Materials and methods: Fifty-three patients with typical TGN underwent GKRS from May 2012 until December 2022. Among these patients, 45 patients who were follow-up for at least 12 months were included in the study. A mean dose of 87.5 Gy (range, 80-90) was administered to the trigeminal nerve. Postoperatively, outcome was considered excellent if the patient was pain- and medication-free. Results: The mean symtpom duration was 9.53 years, and the mean patient age was 59.8 years (range, 34-85). The mean follow-up period was 46.8 months (range, 12-127 months). 46.7% of patients had a history of previous surgical interventions. A single nerve division was affected in 14 patients (31.1%), and multiple divisions were affected in 31 patients (68.9%). The rate of initial pain relief was 80%. Hypoesthesia in the area of trigeminal nerve developed in 30 (66.7%). Twenty patients (44.4%) exhibited excellent results within 72.4 months. Recurrence occurred in 11 patients (24.4%) with 27.6 months. Conclusions: Our results suggest that GKRS is a safe and effective procedure. Thus, it is an attractive first- and second-line treatment choice for TGN.

Abstract	The present study aimed to evaluate the reasons behind the fact that some individuals did not contract coronavirus disease 2019 (COVID-19), considering certain socio-demographic data. The present cross-sectional study was conducted at a state hospital between February 1, 2022 and March 1, 2022. The study group consisted of individuals who never had COVID-19, and the control group consisted of individuals who did not know at the time of the study whether they had COVID-19. A data collection form consisting of 29 questions created based on a literature review was used. A total of 2,958 subjects (study group, 669; control group, 2,289) were included; of these, 53.1% were females and 46.9% were males. It was found that housewives (P<0.001), individuals with secondary school and lower education levels (P=0.02), those residing in rural areas (P=0.003), those who received a combination vaccine (P<0.001), those with chronic diseases (P=0.016), those who consumed more fruits (P=0.001), those who used N95 masks (P=0.002), those with pets (P<0.001) and those who did not follow the news regarding COVID-19 (P=0.016) had a higher probability of not contracting COVID-19. On the whole, the present study observed that socio-demographic factors affected the non-COVID-19 status.
