Electrical stimulation of the frontal cortex enhances slow-frequency EEG activity and sleepiness.

Our aim was to enhance the spontaneous slow-frequency EEG activity during the resting state using oscillating transcranial direct currents (tDCS) with a stimulation frequency that resembles the spontaneous oscillations of sleep onset. Accordingly, in this preliminary study, we assessed EEG after-effects of a frontal oscillatory tDCS with different frequency (0.8 vs.

Hemodynamic Effects, Safety, and Feasibility of Intravenous Esmolol Infusion During Takotsubo Cardiomyopathy With Left Ventricular Outflow Tract Obstruction: Results From A Multicenter Registry.

Background: Left ventricular outflow tract obstruction (LVOTO) may complicate an episode of Takotsubo cardiomyopathy (TTC), potentially leading to cardiogenic shock. Beta-blockers are considered the most suitable treatment for such complication.

Aim Of The Study: The objective of this study was to evaluate the hemodynamic effects, safety, and feasibility of a selective beta-blocker (β1) with a short half-life, esmolol, in subjects with a TTC episode.

Mapping changes in cortical activity during sleep in the first 4 years of life.

A coherent body of evidence supports the notion that sleep is a local and use-dependent process. Significant changes in brain morphology and function occur in the first years of life, revealing a postero-anterior trajectory of cortical maturation. On this basis, a recent study demonstrated that regional cortical maturation between early childhood and late adolescence is reflected in regional changes of sleep slow wave activity (SWA) during non-rapid eye movement (NREM) sleep.

Frequency-dependent effects of oscillatory-tDCS on EEG oscillations: a study with Better OSCillation detection method (BOSC).

Oscillating transcranial direct current stimulation (osc-tDCS) modulates the spontaneous brain activity in a frequency-specific manner. Most studies evaluated cortical effects of osc-tDCS through spectral measures, without differentiating components associated with rhythmic and non-rhythmic activity. Since osc-tDCS mainly affects brain oscillatory activity, our aim was to investigate on the specific changes of EEG oscillations following a frontal osc-tDCS at 0.

The assessment of somatosensory cortex plasticity during sleep deprivation by paired associative stimulation.

Many animal studies suggest that during sleep deprivation (SD) synaptic strength should progressively increase, leading to the saturation of the ability to induce long-term potentiation (LTP). Nevertheless, direct evidences about the effects of sustained wakefulness on cortical plasticity in humans are still lacking. The aim of the present study was to assess changes in the ability to induce LTP-like mechanism in humans during a period of SD by means of a paired associative stimulation (PAS) protocol, which combines median nerve stimulation with transcranial magnetic stimulation (TMS) applied over the contralateral somatosensory cortex.

Dopaminergic system and dream recall: An MRI study in Parkinson's disease patients.

We investigated the role of the dopamine system [i.e., subcortical-medial prefrontal cortex (mPFC) network] in dreaming, by studying patients with Parkinson's Disease (PD) as a model of altered dopaminergic transmission.

Activation of the motor cortex during phasic rapid eye movement sleep.

When dreaming during rapid eye movement (REM) sleep, we can perform complex motor behaviors while remaining motionless. How the motor cortex behaves during this state remains unknown. Here, using intracerebral electrodes sampling the human motor cortex in pharmacoresistant epileptic patients, we report a pattern of electroencephalographic activation during REM sleep similar to that observed during the performance of a voluntary movement during wakefulness.

Clinical follow-up of atrial-fibrillation patients treated with novel oral anti-coagulants: A multi-disciplinary consensus from the Apulia section of the Italian Association of Hospital Cardiologists (ANMCO).

The clinical use of novel oral anti-coagulant (NOAC) drugs is actually regulated in Italy by bureaucratic restrictions; clinical prescription of NOACs preliminarily requires an online prescription plan which should be compiled on the Italian Drug Agency website. The prescription plan has 1-year validity and clinical condition of the patient treated with NOACs should be reassessed at 1-year prescription renewal. Only few specialists are presently allowed to prescribe NOACs: cardiologists, geriatricians, neurologists, hematologists and internists; general practitioners (GPs) are not currently allowed to prescribe NOACs, although they are the most in proximity with the patient.

The CAPITAL study (CArdiovascular Prevention wIth Telecardiology in ApuLia): preliminary results.

Background: The CArdiovascular Prevention wIth Telecardiology in ApuLia (CAPITAL) study aimed to investigate the prevalence of cardiovascular risk factors, the status of cardiovascular prevention, and the compliance to international scientific societies' guidelines on cardiovascular prevention in a Mediterranean region.

Methods: The CAPITAL study was based on the assessment of cardiovascular risk and compliance to guidelines on cardiovascular prevention, and on an electrocardiogram screening with remote telemedicine support performed in pharmacies of Apulia (Italy); the study was expected to enroll 10 000 consecutive patients accessing their usual pharmacy.

Results: In the first 1000 patients enrolled, 16% were smokers, 9% diabetic, 26% hypertensive, 43% overweight, and 23% obese; 37% of the patients treated with antihypertensive drugs did not achieve the target levels, regardless of the number of antihypertensive drugs given, and 60% of subjects treated with lipid-lowering drugs did not achieve the target levels.

Inferior ST-Elevation Acute Myocardial Infarction or an Inferior-Lead Brugada-like Electrocardiogram Pattern Associated With the Use of Pregabalin and Quetiapine?

The Brugada electrocardiogram pattern is characterized by coved-type ST-elevation (>2 mm) in the right precordial leads. We report the case of a 62-year-old man, with bipolar disorder, admitted to the emergency department because of dyspnea and chest discomfort. The patient was on treatment with pregabalin and quetiapine.

State- or trait-like individual differences in dream recall: preliminary findings from a within-subjects study of multiple nap REM sleep awakenings.

We examined the question whether the role of EEG oscillations in predicting presence/absence of dream recall (DR) is explained by "state-" or "trait-like" factors. Six healthy subjects were awakened from REM sleep in a within-subjects design with multiple naps, until a recall and a non-recall condition were obtained. Naps were scheduled in the early afternoon and were separated by 1 week.

Diagnostic accuracy of heart murmur in newborns with suspected congenital heart disease.

Background: The correlation between heart murmur and congenital heart disease (CHD) is complex and varies with observed population.

Methods: Ninety consecutive newborns (41 with heart murmur and 49 controls) were routinely examined with auscultation and echocardiography. Intensity and characteristics of heart murmur, presence and type of CHD were recorded.

Emotional memory processing is influenced by sleep quality.

Objective: The recall of emotional memory is enhanced after sleep and is hindered by sleep deprivation. We used an emotional memory task to assess whether poor sleep quality, as well as sleep deprivation, may influence the accuracy of memory recognition, but also the affective tone associated with the memory.

Methods: Seventy-five subjects, divided into poor sleeper (PS), good sleeper (GS), and sleep deprivation (SD) groups, completed two recall (R) sessions: R1, 1 h after the encoding phase; and R2, after one night of sleep for PS and GS groups and after one night of sleep deprivation for the SD group.

EEG topography during sleep inertia upon awakening after a period of increased homeostatic sleep pressure.

Objective: Behavioral and physiological indexes of high sleep inertia (SI) characterize the awakening from recovery (REC) sleep after prolonged wakefulness, but the associated electroencephalogram (EEG) topography has never been investigated. Here, we compare the EEG topography following the awakening from baseline (BSL) and REC sleep.

Methods: We have recorded the EEG waking activity of 26 healthy subjects immediately after the awakening from BSL sleep and from REC sleep following 40 h of prolonged wakefulness.

EEG oscillations during sleep and dream recall: state- or trait-like individual differences?

Dreaming represents a peculiar form of cognitive activity during sleep. On the basis of the well-known relationship between sleep and memory, there has been a growing interest in the predictive role of human brain activity during sleep on dream recall. Neuroimaging studies indicate that rapid eye movement (REM) sleep is characterized by limbic activation and prefrontal cortex deactivation.

Gender differences in sleep deprivation effects on risk and inequality aversion: evidence from an economic experiment.

Excessive working hours--even at night--are becoming increasingly common in our modern 24/7 society. The prefrontal cortex (PFC) is particularly vulnerable to the effects of sleep loss and, consequently, the specific behaviors subserved by the functional integrity of the PFC, such as risk-taking and pro-social behavior, may be affected significantly. This paper seeks to assess the effects of one night of sleep deprivation on subjects' risk and social preferences, which are probably the most explored behavioral domains in the tradition of Experimental Economics.
