The importance of heart rate variability in predicting cardiac autonomic dysfunction in patients with amyotrophic lateral sclerosis
(John Wiley and Sons Inc, 2021) İşcan, Dilek; Karaaslan, Muhammet Buğra; Deveci, Onur Sinan; Akıllı Eker, Rabia; Koç, Filiz
Aim: Amyotrophic lateral sclerosis (ALS) is a progressive disease characterized by degeneration in the upper and lower motor neurons of the corticospinal tract, brain stem, and spinal cord. Recent studies have revealed that the disease does not present solely with motor neuron involvement. Accordingly, the aim of this study is to investigate the presence of cardiac autonomic impairment in patients diagnosed with ALS. Material and Method: A total of 61 patients, who were diagnosed with ALS according to the Revised El Escorial Criteria (R-EEC), were included in this prospective study, in addition to the 29 healthy individuals, who were included in the study as controls. In order to assess the cardiac autonomic involvement, the presence of orthostatic hypotension was investigated, and transthoracic echocardiography and 24-hour electrocardiogram (ECG) using a Holter monitor were performed. Results: Orthostatic hypotension was detected in 14 (22.2%) patients. Holter electrocardiogram results of the patient group revealed statistically significantly lower heart rate variability (HRV) indicators in the time domain (SDNN, SDANN, SDNN index, rMSSD, and pNN50) and in the frequency domain (high frequency [HF], low frequency [LF], and very low frequency [VLF]) than those of the control group (P <.05). Conclusion: Contrary to the popular opinion, cardiac autonomic dysfunction in patients with ALS can occur at any stage of the disease. Therefore, it is recommended that the patients are evaluated via periodic examinations during the follow-up period for cardiac autonomic involvement.
Medications and lifestyles of patients with cardiovascular risk factors and/or disease in turkish patients (medlife-tr)

Background and Aim: Lifestyles and behavoiral patterns of patients must be known to improve public health and to prevent cardiovascular diseases (CVD). In this study, we aimed to provide insights into the lifestyles and behavioral patterns of patients applied to outpatient cardiology clinics in Turkey. Materials and Methods: The participants completed a self-administered questionnaire about awareness of cardiovascular (CV) risk factors and individual CV risk levels, lifestyles, and medications. Results: A total of 2793 patients, 52.1% of females with a mean age of 57.0 ± 14.0 years were included. The most common risk factor was hypertension. The most common CVD was coronary artery disease. The calculated CV risk level of 1041 patients (37.3%) was high, while only 20.4% of all participants identified themselves as high risk. Participants were aware that hypertension, smoking, hyperlipidemia, diabetes, sedentary, family history, and aging were risk factors for CVD. About 44% of the patients reported that they used additional salt and the majority reported that they did not consume fast food. The most commonly prescribed CV drug was beta-blockers (44.9%) and 22.4% of patients were taking minimum of 5 drugs daily. Conclusion: The awareness of CV risk factors and risk levels is low in the study population. Guideline recommended medications and lifestyle changes are not sufficiently implemented.

A classification of submanifolds of (κ, µ)-paracontact metric space forms
(Mehmet Zeki SARIKAYA, 2021) Atçeken, Mehmet; Uygun, Pakize
The aim of this paper is to study the invariant submanifolds of a (κ, µ)-paracontact metric space form. We characterize (κ, µ)-paracontact metric space form satisfying the curvature conditions ∇σ=0, R · σ = 0, R · ∇σ = 0 and ˜C · σ = 0. Finally, we see that these conditions are equivalent to σ = 0.
Some special ruled surfaces in hyperbolic 3−space
(Mehmet Zeki SARIKAYA, 2021) Mert, Tuğba; Atçeken, Mehmet
In this paper, normal and binormal surfaces, a special class of ruled surfaces in hyperbolic 3−space, are discussed. These special surfaces are defined in hyperbolic 3−space and the types of these surfaces are introduced. The properties of these surfaces are given under the condition of being constant angle surfaces in hyperbolic 3−space.
