(2020) Kayipmaz, Selvi; San, Ishak; Usul, Eren; Korkut, Semih; 0000-0002-7984-2440; 32440830; AAK-3227-2021
We aimed to reveal the relationship between the meteorological variables and suicide rates (completed suicides and suicide attempts) independently of the seasonal cycle and holiday effects. This is an observational retrospective study. We collected the data on age, gender, and suicide method of all suicide cases transferred to hospitals from the scene by emergency medical services as well as those cases in which the victim died on the scene between January 1, 2017 and June 30, 2019. We also collected data on maximum, minimum, and average temperatures (degrees C), average humidity (%), and average actual pressure (hPa) measured daily in Ankara. The total number of cases due to suicide between the given dates was 6777. The suicide method in 60.1% of the cases was drug poisoning, which was the most common suicide method. Investigating the effect of meteorological variables on suicide cases (suicide attempts and completed suicides), the present study found that after smoothing the effect of the day of the week and seasonality, an increase in the minimum temperature on the day of the application by 1 unit (1 degrees C degree) leads to an increase in the number of suicides by 0.01 point (0.01 +/- 0.005, p = 0.046). There was no significant change in the variables other than the minimum temperature. We believe that the results of the present study will contribute to growing body literature about the epidemiology of suicide. We also believe that there is a need for large-scale studies that include individual data to reveal causality.
THE INVESTIGATION OF THE USE OF EMERGENCY MEDICAL SERVICES FOR GERIATRIC PATIENTS DUE TO SUICIDE

Introduction: Ageing is a physiological process, and inevitable psychological and physical changes occur after the age of 65 in every individual. Elderly suicide is a crucial public health concern that is still largely ignored worldwide. The purpose of this study is to investigate the use of emergency medical services by geriatric patients due to suicide. Materials and Method: We obtained the demographic and clinical information of the patients from the records. We retrospectively examined the data of all patients, who are 65 and older, enrolled in Turkey for the suicide attempt between September 2018 and August 2019. Results: Our study included 769 cases. There was a statistically significant difference between the two genders in terms of the number of completed suicides (p <0.001). The most common suicide method was drug use (30.8%). In total, 36.7% of women and 62.7% of men used violent methods for suicide. We found a statistically significant difference between the groups in terms of violent method usage (p <0.001). There was a statistically significant difference between the age groups in terms of completed suicide percentages (p = 0.008), and the cases reported from urban and rural areas in terms of mortality (p <0.001). Conclusion: The percentage of completed suicides increases with age, and the careful evaluation of suicide attempts is vital in reducing the risk of suicide-related death. The process starting from the moment of notification of suicide attempt to the emergency dispatch centre must be managed effectively and quickly by trained and experienced medical teams.
Lithium Intoxication: A Possible Interaction with Moxifloxacin
(2017) Kayipmaz, Selvi; Altinoz, Ali Ercan; Ok, Nadide Elmas Gulcu; 0000-0003-2233-2105; 0000-0002-7984-2440; 29073753; J-4811-2014; AAK-3227-2021
Lithium is a well-known treatment for patients with mood disorders. Intoxication by lithium may be lethal particularly in elderly due to altered pharmacokinetics, renal impairment or multiple drug use. We presented a 74-year-old female patient who had been stabile with lithium carbonate 600 mg/day for 5 years and developed lithium intoxication after bronchiolitis. She presented with altered mental status. The neurological signs resolved slowly after lithium and moxifloxacin were stopped immediately and fluid resuscitation administered. Considering possible drug interactions on elderly patients receiving lithium is essential.
Obsessive-Compulsive Disorder From Embodied Cognition Perspective
(2022) Kocak, Orhan Murat; Kayipmaz, Selvi; Kutluturk Uney, Pelin; Haciyev, Ceyhun; https://orcid.org/0000-0002-7984-2440; AAK-3227-2021
Obsessive Compulsive Disorder (OCD) is characterized by problems of control over behavior and cognition. Although almost all of the studies on pathogenesis of OCD point out fronto-striatal dysfunction, it is still not possible to reveal mechanisms to explain the entire clinical course of OCD through these circuits. A more holistic explanation can be given through the Embodied Cognition (EC) perspective, which suggests that the alteration/dysfunction of low-level sensory-motor process may appear as a multifarious extent of dysfunction of high-level cognitive processes. Fronto-striatal circuits play fundamental role in behavioral control. These circuits also have a central role for the feed-forward motor control (FFMC). In FFMC, the internal model of movement is driven by efference copies as templates for motor behavior, without being adjusted by sensory information. If impairment of low-level sensory-motor processing is crucial to occurrence of compulsions, one possible hypothesis about this impairment is the problem which emerges from occurrence of efference copy in FFMC. On the other hand, the efference copy has also pivotal role for subject's feeling of the agency of an action. Therefore, there may be role of failure in reproduction of the efference copy in the background of subjects' experience of losing control on compulsive behaviors. In this paper, we will discuss how the EC perspective which can be one of the biological bases of computationalism, which brings neuroscientific explanations on the functioning of nervous system to a more symbolic perspective, may contribute to our understanding of etiopathogenesis of OCD. In this perspective, our method will be to integrate the theoretical basis provided by EC perspective to the current models for OCD, rather than falsifying them.
