The effect of quarantine due to Covid-19 pandemic on seizure frequency in 102 adult people with epilepsy from Apulia and Basilicata regions, Southern Italy
Objective: following the COVID-19 pandemic, a quarantine was imposed to all of regions Italy by 9th March until 3rd May 2020. We investigated the effect of COVID-19 infection and quarantine on seizure frequency in adult people with epilepsy (PwE) of Apulia and Basilicata regions, Southern Italy.
Methods: This is an observational, retrospective study based on prospective data collection of 102 successive PWE. The frequency of seizures was evaluated during pre-quarantine (January- February), quarantine (March-April), and post-quarantine period (May-June), while PwE were divided into A) cases responding to treatment with †1 seizure per year; B) cases responding to treatment with 2-5 seizure per year; C) cases with drug-resistant epilepsy with †4 seizures per month; D) cases with drug-resistant epilepsy with 5-10 seizures per month. PwE underwent several self-report questionnaires regarding therapeutic compliance, mood, stress and sleep during quarantine period.
Results: Approximately 50 % of PwE showed seizure frequency changes (22.55 % an increase and 27.45 % a reduction) during quarantine. Seizure frequency significantly (p < 0.05) increased in PwE responding to treatment with †1 seizure per year, while significantly (p < 0.05) reduced in PwE with drug-resistant epilepsy with 5-10 seizures per month. The data was not influenced by therapeutic adherence, sleep and depression. The analysis of anxiety showed a moderate level of anxiety in PwE responding to treatment with < 1 seizure per year, while moderate stress was perceived by all PwE. Seizure frequency changes were related to quarantine, but not to COVID-19 infection. In fact, unlike other regions of Italy, particularly Northern Italy, Apulia and Basilicata regions were less affected by COVID-19 infection, and almost all PwE recognized the quarantine as a stressful event. Emotional distress and anxiety due to social isolation, but also the relative reduction of triggers for epileptic seizures were the most important factors for changes in seizure frequency.
Conclusions: Our study adds to the growing concern that the indirect effects of COVID-19 pandemic will far outstrip the direct consequences of the infection

The poly-omics of ageing through individual-based metabolic modelling
Abstract Background Ageing can be classified in two different ways, chronological ageing and biological ageing. While chronological age is a measure of the time that has passed since birth, biological (also known as transcriptomic) ageing is defined by how time and the environment affect an individual in comparison to other individuals of the same chronological age. Recent research studies have shown that transcriptomic age is associated with certain genes, and that each of those genes has an effect size. Using these effect sizes we can calculate the transcriptomic age of an individual from their age-associated gene expression levels. The limitation of this approach is that it does not consider how these changes in gene expression affect the metabolism of individuals and hence their observable cellular phenotype. Results We propose a method based on poly-omic constraint-based models and machine learning in order to further the understanding of transcriptomic ageing. We use normalised CD4 T-cell gene expression data from peripheral blood mononuclear cells in 499 healthy individuals to create individual metabolic models. These models are then combined with a transcriptomic age predictor and chronological age to provide new insights into the differences between transcriptomic and chronological ageing. As a result, we propose a novel metabolic age predictor. Conclusions We show that our poly-omic predictors provide a more detailed analysis of transcriptomic ageing compared to gene-based approaches, and represent a basis for furthering our knowledge of the ageing mechanisms in human cells
Molecular mechanisms of cell death: recommendations of the Nomenclature Committee on Cell Death 2018.
Over the past decade, the Nomenclature Committee on Cell Death (NCCD) has formulated guidelines for the definition and interpretation of cell death from morphological, biochemical, and functional perspectives. Since the field continues to expand and novel mechanisms that orchestrate multiple cell death pathways are unveiled, we propose an updated classification of cell death subroutines focusing on mechanistic and essential (as opposed to correlative and dispensable) aspects of the process. As we provide molecularly oriented definitions of terms including intrinsic apoptosis, extrinsic apoptosis, mitochondrial permeability transition (MPT)-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, entotic cell death, NETotic cell death, lysosome-dependent cell death, autophagy-dependent cell death, immunogenic cell death, cellular senescence, and mitotic catastrophe, we discuss the utility of neologisms that refer to highly specialized instances of these processes. The mission of the NCCD is to provide a widely accepted nomenclature on cell death in support of the continued development of the field

Brain SPECT imaging of ictal smile seizure.
"Ictal smile" is defined as a facial expression during a seizure, which usually translates happiness, clearly distinct from a tonic deviation of the mouth or other abnormal tonic-clonic movements involving the face, not associated to any happiness emotion (Epilepsia. 1998;39:1357-1360). It is a rare condition (6%-10% of patients; Epilepsia. 1998;39:1357-1360) and seems to be related to seizures arising from temporal or frontal regions (Brain. 2003;126:21212138). Anecdotal reports of brain perfusion SPECT performed during ictal and interictal phases (Epilepsia. 1998;39:1357-1360) do not supply, unfortunately, imaging documentation. Thus, we report the first evidence of brain perfusion abnormalities induced by ictal smile seizure
Epileptic seizures, movement disorders, breathing disturbances in Rett syndrome: diagnostic relevance of video-polygraphy
Epileptic seizures, movement disorders and breathing disturbances may be observed in Rett syndrome, and correct diagnosis is mandatory for the management. We evaluated the usefulness of video-polygraphy in the differential diagnosis
between epileptic and non-epileptic paroxysmal events in eight patients with Rett syndrome. Based on video analysis, myoclonic seizures were usually misdiagnosed as movement disorders and stereotypies; the events identified by parents as
generalized tonic-clonic seizures included episodes of motor activity and breathing abnormality. Myoclonic seizures aggravated by inappropriate treatment were evident in four patients; hyperventilation and apnea during wakefulness were
present in all patients, while central sleep apneas were present in one patient; sinus tachycardia and cardiac arrhythmias emerged in six patients; cortical myoclonus was disclosed in five patients. In Rett syndrome, video-polygraphy is essential in characterizing the clinical features of paroxysmal events, determining autonomic dysfunctions, documenting myoclonic motor phenomena, and evaluating the responses to the treatment of epilepsy
