ly high, there is great variation between subgroups. These real-life breast cancer data provide tools to further evaluate medical need in different breast cancer subgroups.

The impact of basic atrial rhythm (sinus rhythm [SR] vs. atrial fibrillation [AF]) during AF ablation on efficacy and safety is unknown.

About 3375 patients from the German Ablation Registry undergoing first-time AF ablation were divided according to the type of AF and the basic atrial rhythm during the ablation procedure paroxysmal AF (PAF) and SR [group Ia], PAF and AF [group Ib]), persistent AF and SR (IIa), and persistent AF and AF (IIb).

Patients in SR (n = 2312 [67%]) underwent cryoballoon ablation more often (Ia vs. Ib p = .002 and IIa vs. IIb p = .010, whereas in patients in AF (n = 1063 [33%]) radiofrequency (RF)-based ablation (Ia vs. Ib p = .006 and IIa vs. IIb p = .014) including left and/or right atrial substrate modification was more frequently performed. Depending on the basic rhythm there was no difference regarding arrhythmia recurrence during long-term follow-up. For patients suffering from persistent AF acute procedure-related complications were more often documented when ablated in AF (9.1% vs. 4.6%, p = .012). which was mainly driven by the higher occurrence of pericardial effusion/tamponade. For patients suffering from persistent AF, favorable results were found regarding 366-day Kaplan-Meier estimates of the incidence of MACCE (death, myocardial infarction, and stroke; p = .011) and the composite endpoint of death, myocardial infarction, stroke, and major bleeding (p = .006), when ablated in SR.

Basic atrial rhythm at the time of AF ablation did not affect long-term rhythm outcome. For patients suffering from persistent AF a more favorable acute and long-term safety profile was observed when ablated in SR.

Glutamic acid decarboxylase antibodies (GAD-Ab) are sometimes associated with chronic drug-resistant focal epilepsy. Clinically, it may manifest as mesial temporal lobe epilepsy (mTLE), with GAD-Ab patients difficult to distinguish. SGX-523 in vitro Therefore, the aim of this study is to compare brain metabolism of patients with mTLE and high serum titers of GAD-Ab (>2000 UI/ml) to those with mTLE and hippocampal sclerosis (HS) and confirmed GAD-ab negativity.

Images from PET studies were normalized to an SPM 12 template. Voxel to voxel comparisons were made using a two-sample one-tailed t-test.

In both patients with GAD-Ab and controls (mTLE-HS), hypometabolism in mesial temporal lobe areas was observed. When comparing the two groups, GAD-Ab patients had statistically significant reduced metabolism in both insulae and medial inferior frontal-hypothalamus area (p < 0.001).

Hypometabolism in mesial temporal lobe areas together with hypometabolism in insulae and medial inferior frontal-hypothalamus may be characteristic of patients with epilepsy and GAD-ab. This PET pattern could be a useful diagnostic tool to identify GAD-Ab patients.

Reward-based learning deficits have been shown in both depression and schizophrenia patients. For this study, we compiled studies that investigated prediction error processing in depression and schizophrenia patients and performed a series of meta-analyses. In both groups, positive t-maps of prediction error tend to yield striatum activity across studies. The analysis of negative t-maps of prediction error revealed two large clusters within the right superior and inferior frontal lobes in schizophrenia and the medial prefrontal cortex and bilateral insula in depression. The concordant posterior cingulate activity was observed in both patient groups, more prominent in the depression group and absent in the healthy control group. These findings suggest a possible role in dopamine-rich areas associated with the encoding of prediction errors in depression and schizophrenia.The liquid-liquid phase separation (LLPS) of Tau has been postulated to play a role in modulating the aggregation property of Tau, a process known to be critically associated with the pathology of a broad range of neurodegenerative diseases including Alzheimer's Disease. Tau can undergo LLPS by homotypic interaction through self-coacervation (SC) or by heterotypic association through complex-coacervation (CC) between Tau and binding partners such as RNA. What is unclear is in what way the formation mechanisms for self and complex coacervation of Tau are similar or different, and the addition of a binding partner to Tau alters the properties of LLPS and Tau. A combination of in vitro experimental and computational study reveals that the primary driving force for both Tau CC and SC is electrostatic interactions between Tau-RNA or Tau-Tau macromolecules. The liquid condensates formed by the complex coacervation of Tau and RNA have distinctly higher micro-viscosity and greater thermal stability than that formed by the SC of Tau. Our study shows that subtle changes in solution conditions, including molecular crowding and the presence of binding partners, can lead to the formation of different types of Tau condensates with distinct micro-viscosity that can coexist as persistent and immiscible entities in solution. We speculate that the formation, rheological properties and stability of Tau droplets can be readily tuned by cellular factors, and that liquid condensation of Tau can alter the conformational equilibrium of Tau.Syncope represents a relatively uncommon symptom of supraventricular tachycardia (SVT). It is likely that an impaired autonomic vasomotor response to the hemodynamic stress of tachycardia is the determinant of hemodynamic changes leading to cerebral hypoperfusion and syncope. In this regard, tilt-table test may detect abnormalities in the autonomic nervous function and predict the occurrence of syncope during SVT. Electrophysiology studies may reproduce the SVT, distinguish it from other life-threatening ventricular tachyarrhythmias, and exclude other causes of syncope. Not infrequently mixed syncope mechanisms are revealed during the above diagnostic workup raising doubts about the operating mechanism in the clinical setting. In such cases of uncertainty, an implantable loop recorder, providing long-term cardiac monitoring, may play a pivotal role in the establishment of the diagnosis, confirming the association of an arrhythmic event with the symptom. Herein, we present four such cases with recurrent unexplained syncope finally attributed to paroxysmal SVT guiding them to a potentially radical treatment through radiofrequency catheter ablation.
