Background: Jailed wire (JW) in the side branch (SB) is recommended during coronary bifurcation provisional stenting, but real benefit is unsure. Our objective was to evaluate benefit of a JW technique in the CABRIOLET registry.

Methods: In CABRIOLET, including 500 patients, we compared the primary composite endpoint poor final SB angiographic result (TIMI flowB, thrombosis, residual stenosis>70%, or additional SB stenting) whether JW was performed or not.

Background: Fractional flow reserve (FFR) or non-hyperaemic pressure ratios are recommended to assess functional relevance of intermediate coronary stenosis. Both diagnostic methods require the placement of a pressure wire in the coronary artery during invasive coronary angiography. Quantitative flow ratio (QFR) is an angiography-based computational method for the estimation of FFR that does not require the use of pressure wires.

Article Synopsis
  • The study aimed to analyze the patterns of scalp EEG during occipital seizures (OS) and how they relate to simultaneous intracerebral EEG readings.
  • Researchers monitored 8 patients with confirmed OS, observing different seizure patterns including background activity suppression and high amplitude slow waves, with varied initial presentations across different regions of the brain.
  • The findings indicate that while scalp EEG can effectively pinpoint the onset of intracerebral seizures and carry lateralizing value, it does not always correlate with occipital electrode activity, emphasizing the complexity of seizure manifestations and aiding in better surgical planning for epilepsy treatment.

Article Synopsis
  • Patients who need oral anticoagulation and undergo coronary intervention can use a special stent (COBRA PzF) that may lower the need for long-term dual antiplatelet therapy (DAPT) while maintaining safety against blood clots.
  • In a study, 996 patients were randomized to receive either the COBRA PzF stent with a short 14-day DAPT or a regular stent with longer DAPT durations of 3 to 6 months.
  • Results showed that the COBRA stent did not significantly reduce bleeding compared to the control group and was not proven to maintain equivalent safety for thromboembolic events, indicating further investigation is needed.

Article Synopsis
  • - The Basal Temporal Language Area (BTLA) is identified in epilepsy surgery when stimulation in the ventral temporal cortex (VTC) causes naming difficulties like anomia or paraphasia, highlighting the need for a better understanding of this language area.
  • - A study using cortico-cortical evoked potentials in nine epilepsy patients found strong connectivity in eloquent regions of the left VTC, indicating a structured basal temporal language network (BTLN) that interacts closely with brain areas like the amygdala and hippocampus.
  • - The fusiform gyrus serves as a multimodal integrator within this network, enhancing our comprehension of how the ventral temporal region processes language.

A major scientific objective of cognitive neuroscience is to define cortico-cortical functional connections supporting cognitive functions. Here, we use an original approach combining frequency-tagging and direct electrical stimulation (DES) to test for bidirectional and cross-hemispheric category-specific modulations within the human cortical face network. A unique patient bilaterally implanted with depth electrodes in multiple face-selective cortical regions of the ventral occipito-temporal cortex (VOTC) was shown 70 s sequences of variable natural object images at a 6 Hz rate, objectively identifying deviant face-selective neural activity at 1.

The proportion of patients becoming seizure-free after epilepsy surgery has stagnated. Large multi-center stereo-electroencephalography (SEEG) datasets can allow comparing new patients to past similar cases and making clinical decisions with the knowledge of how cases were treated in the past. However, the complexity of these evaluations makes the manual search for similar patients impractical.

Background And Purpose: Our objective was to define phenotypes of non-lesional late-onset epilepsy (NLLOE) depending on its presumed aetiology and to determine their seizure and cognitive outcomes at 12 months.

Methods: In all, 146 newly diagnosed NLLOE patients, >50 years old, were prospectively included and categorized by four presumed aetiological subtypes: neurodegenerative subtype (patients with a diagnosis of neurodegenerative disease) (n = 31), microvascular subtype (patients with three or more cardiovascular risk factors and two or more vascular lesions on MRI) (n = 39), inflammatory subtype (patient meeting international criteria for encephalitis) (n = 9) and unlabelled subtype (all individuals who did not meet the criteria for other subtypes) (n = 67). Cognitive outcome was determined by comparing for each patient the proportion of preserved/altered scores between initial and second neuropsychological assessment.

Neuroimaging and intracranial electrophysiological studies have consistently shown the largest and most consistent face-selective neural activity in the middle portion of the human right lateral fusiform gyrus ('fusiform face area(s)', FFA). Yet, direct evidence for the critical role of this region in face identity recognition (FIR) is still lacking. Here we report the first evidence of transient behavioral impairment of FIR during focal electrical stimulation of the right FFA.

Objective: Heterozygous variations in microtubule-associated serine/threonine kinase 1 gene (MAST1) were recently described in the mega-corpus-callosum syndrome with cerebellar hypoplasia and cortical malformations (MCCCHCM, MIM 618273), revealing the importance of the MAST genes family in global brain development. To date, patients with MAST1 gene mutations were mostly young children with central nervous system involvement, impaired motor function, speech delay, and brain magnetic resonance imaging (MRI) abnormalities. Here, we report the clinical presentation of an adult patient with a rare and de novo MAST1 mutation with central hypogonadism that could extend this phenotype.

Faces are critical for social interactions and their recognition constitutes one of the most important and challenging functions of the human brain. While neurons responding selectively to faces have been recorded for decades in the monkey brain, face-selective neural activations have been reported with neuroimaging primarily in the human midfusiform gyrus. Yet, the cellular mechanisms producing selective responses to faces in this hominoid neuroanatomical structure remain unknown.

Article Synopsis
  • The study investigated the role of brain-derived neurotrophic factor (BDNF) in epilepsy, specifically looking at its potential as a biomarker for epilepsy severity and related psychiatric conditions.
  • It analyzed serum BDNF levels in epilepsy patients from four centers in France, while documenting various clinical characteristics and conducting psychiatric screenings.
  • The results showed no significant correlation between serum BDNF levels and epilepsy features or depression, but found that the presence of anti-seizure medications (ASM) was linked to increased BDNF, especially with valproate and perampanel.

Objective: Describe the diagnostic workup and postoperative results for patients treated by adrenalectomy for primary aldosteronism in France from 2010 to 2020.

Background: Primary aldosteronism (PA) is the underlying cause of hypertension in 6% to 18% of patients. French and international guidelines recommend CT-scan and adrenal vein sampling as part of diagnostic workup to distinguish unilateral PA amenable to surgical treatment from bilateral PA that will require lifelong antialdosterone treatment.

Patients with anterior temporal lobe (ATL) resection due to mesial temporal lobe epilepsy (MTLE) have difficulties at identifying familiar faces and explicitly remembering newly learned faces but their ability to individuate unfamiliar faces remains largely unknown. Moreover, the extent to which their difficulties with familiar face identity recognition and learning is truly due to the ATL resection remains unknown. Here, we report a study of 24 MTLE patients and matched healthy controls tested with an extensive set of seven face and visual object recognition tasks (including three tasks evaluating unfamiliar face individuation) before and about 6 months after unilateral (nine left, 15 right) ATL resection.

Background: Electrophysiological impairments in the magnocellular visual system have been reported among patients with schizophrenia, but previous theories proposed that these deficits may begin in the retina. We therefore sought to evaluate the potential contribution of the retina by comparing retinal and cortical visual electrophysiological impairments between patients with schizophrenia and healthy controls.

Methods: We recruited patients with schizophrenia and age- and sex-matched healthy controls.
