Monotony is the result of continuous predictive or repetitive stimulations and can be considered a functional state of the central nervous system, a state characterized by lowered cerebral activity. The present work investigates the effect of monotonous auditory input on cerebral electrical activity. This was done by means of recording the EEG under three different auditory stimuli (S1, S2, S3), on 11 volunteers (average age 23 years). Data were acquisitioned during 20 minutes of auditory stimulation, with a 5 minute period of silence before and after stimulation. The characteristic features of each obtained EEG pattern depends closely on the type of the musical composition. Thus, the highest domain of variance generated under stimulation by S3 (fragments of the Mozart’s K448 Sonata) is for the frequency bands Alfa1, Beta2 and Theta, while in case of S2 (recording of a rainforest) it is for bands Delta, Beta1 and Alfa2, and in case of S1 (recording of a car driving over a rough road) is only slightly elevated for the total frequency spectrum. By comparing the period of auditory stimulation with the post-stimulation period, in case of S3 the fewest statistically significant mean values are noticeable (only for Delta and Theta indexes), in contrast to S1, which presents statistically significant differences between mean values for high frequency bands. In case of S2, statistically significant differences between mean values are similar to S3, with the addition of the Beta1 frequency band. In conclusion, each different auditory stimuli produces a characteristic pattern of changes in cortical micropotentials which could be associated with the induced psychoemotional state

Pulmonary arterial systolic pressure elevation in young athletes is associated with pronounced right ventricular enlargement, even when compared to matched athletes. Conventional and speckle tracking echocardiography showed preserved right ventricular function.

Periodontitis is a common complication in patients with diabetes. Their classification is complex and it is based on the clinical presentation

Diabetic neuropathy is the most common cause of neuropathy worldwide and it is estimated to affect about half of people with diabetes. The goal of our study is to compare the effectiveness of thioctic acid treatment alone versus the efficacy of thioctic acid plus vitamin B complex in patients with diabetic peripheral polyneuropathy (DPN). We conducted a prospective, observational study staring from October 2017 to December 2018, in which we included 56 DPN patients. Depending on the Michigan neuropathic screening instrument (MNSI) we divided the patients into two subgroups: patients with MNSI [7 and patients whose MNSI did not decrease sufficiently during the therapeutic protocol. 36 patients (64.2%) of the total patients enrolled in the study had an MNSI [7 at one of the follow-up meetings. These patients were also divided according to the therapeutic protocol applied in a group of patients who were treated with only thioctic acid (TA group) and in a group of patients who were treated with thioctic acid plus vitamin B complex (TA + B group). We noticed a greater proportion of patients who had a MNSI [7 in the TA + B group. This study revealed that the treatment of peripheral diabetic neuropathy with thioctic acid plus Vitamin B complex compared to thioctic acid alone was superior in terms of improving clinical features.
