This study investigates the cognitive levels of tugboat captains, key players during port manoeuvres, which are a crucial part of sea navigation. The objective is to reveal the main neurophysiological findings related to the measurements of the tugboat captains' brain activity during both rest and actual manoeuvring performance and to investigate the relationship between this brain activity and situational awareness. The study employed an experimental research method. Brain waves of the tugboat captains were recorded using the Emotiv X EEG device and the Emotiv Pro v2.0 program during real port manoeuvres which is a part of the sea navigation. Situational awareness levels were tried to be determined by analysing the obtained values in the Brain Products Vision Analyzer 2.1 software. The study examined the cognitive states of four tugboat captains during 16 manoeuvres and resting, focusing on the Fast Fourier Transform (FFT)/Band power graph values. Within the scope of the research non-parametric Friedman Test with five variables [Resting State (RS), 1st Manoeuvre Group, 2nd Manoeuvre Group, 3rd Manoeuvre Group, and 4th Manoeuvre Group] to analyse the FFT values of the participants. Post-hoc comparisons were calculated using Bonferroni correction. The results showed no difference in alpha wave power, while delta, theta, beta, and gamma power decreased. The primary outcome of the research indicates that professional tugboat captains, who were the participants of the study, exhibited consistent situational awareness levels both during manoeuvring and resting moments.

Intermittent rhythmic delta activities are electroencephalographic discharges with uniform morphology, at a frequency of 4 Hz or less, containing at least six cycles, lost by eye opening and stimulation. These are called "plus" if concomitant theta or higher frequency rapid activity or spike, sharp wave activity is present. This group has a stronger relationship with epileptiform abnormality. We aimed to discuss the clinical presentations, and nomenclature of intermittent rhythmic delta activities with three case reports. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to determine the prevalence of periodic leg movements (PLMs) in patients who underwent polysomnographic examinations and to compare the demographic and polysomnographic characteristics of patients with and without PLM. Materials and Methods: The demographic features and polysomnographic parameters of 491 patients were recorded. The patients were divided into two groups: PLMI ≤15 and >15. Patients with PLMI >15 and ≤15 and were defined as those with and without PLMI, respectively. All patients were grouped based on their sex and age. Results: Fifty-nine patients (12 men and 35 women) had PLMI >15. The age of the patients with PLM was significantly higher than that of those without PLM (p=0.05). When the groups were examined based on sex, in men, total sleep time (TST) in the non- PLM group and sleep time and sleep latency after sleep onset in the PLM group were significantly prolonged (p<0.05). Meanwhile, in women, only TST in the non-PLM group was significantly increased. Conclusion: PLM is a sleep-related movement disorder that is often unnoticeable by patients but may cause fatal consequences, leading to cardiovascular or cerebrovascular events. Further studies are needed to better understand the clinical significance of this disease, which is diagnosed by polysomnography. [ABSTRACT FROM AUTHOR]

Catathrenia is a sleep-related respiratory disorder characterized by groaning during sleep. This situation is usually not noticed by the affected individuals themselves but is often indicated by family members or bed partners. This disorder, the cause of which is not completely known, is extremely rare. In this case report, a patient who admitted with a complaint of groaning and diagnosed with catahtrenia by polysomnography was presented with its clinical and electrophysiological features. In addition to drawing attention to the fact that catathrenia may be confused with the central sleep apnea pattern in polysomnography, it was emphasized that it should be considered in the differential diagnosis because of a limited number of cases reported in the literature.

Objective: To demonstrate a correlation between neuroendocrine hormone changes in menopause and obstructive sleep apnea syndrome (OSAS), excluding risk factors, i.e., depression, and treatment of cases where the disease has been diagnosed. Methods: This was a case study (2009-2010) of 194 menopausal patients, excluding surgically induced cases, performed at the Obstetrics and Gynocology Clinic of Dokuz Eylül University School of Medicine Hospital. Results: Patients were queried on their demographic data, menopause and OSAS symptoms, and Epworth Sleepiness Scale (ESS) results. Fourteen patients having 10 points and above in the ESS were hospitalized for one night in Dokuz Eylül University Sleep Center and underwent polysom-nography (PSG). In our study, OSAS prevalence for postmenopausal patients was found in 6.21% of the patients. Further, 28.6% of 12 patients having OSAS were found to have mild and 57.2% were found to have moderate-severe OSAS. By PSG, 14 patients were detected to have 398.5 min of average sleep time and 23.9 of Apnea-Hypopnea Index. Three patients were suggested to undergo the palliative care and 9 were suggested to undergo continuous positive airway pressure (CPAP) therapy. The average CPAP was 7.1 mmHg. A correlation was found between body mass index and LH, prolactin, E2, and free testosterone levels and OSAS. Conclusion: OSAS risk increases during menopause. Menopause is an independent risk factor for OSAS: therefore, detailed research with PSG is suggested to be performed when required. [ABSTRACT FROM AUTHOR]
