BACKGROUND: Cardiac problems have been suggested as causes of sudden unexpected death in epilepsy (SUDEP). Our aim was to investigate possible associations of cardiac autonomic functions based on heart rate variability (HRV) parameters with risk factors of SUDEP in patients with drug-resistant epilepsy. METHODS: Forty-seven patients with drug-resistant seizures and 45 healthy control subjects were enrolled in the study. Interictal time domain parameters of HRV were evaluated with 24-hour Holter recordings...

This study examines the impact of a death and dying course on 39 undergraduate students' attitudes and anxieties about death. Authors outline key aspects of the curriculum used in the course and discuss how the approach lends itself to a transformative learning experience related to death and loss, preparing students who will face clients with a variety of needs in these areas across practice settings. The majority of students ( n = 34) experienced a decrease in death avoidance, fear of death, and overall death anxiety...

We report a comprehensive computational dissection of the domain architecture of the SAMD9 family proteins that are involved in antivirus and antitumor response in humans. We show that the SAMD9 protein family is represented in most animals and also, unexpectedly, in bacteria, in particular actinomycetes. From the N to C terminus, the core SAMD9 family architecture includes DNA/RNA-binding AlbA domain, a variant Sir2-like domain, a STAND-like P-loop NTPase, an array of TPR repeats and an OB-fold domain with predicted RNA-binding properties...

There are limited data on the safety and efficacy of switching to secukinumab from cyclosporine A (CyA) in patients with psoriasis. The purpose of the present study was to assess the efficacy and safety of secukinumab for 16 weeks after direct switching from CyA in patients with moderate-to-severe psoriasis. In this multicenter, open-label, phase IV study, 34 patients with moderate-to-severe psoriasis and inadequate response to CyA received secukinumab 300 mg s.c. at baseline and weeks 1, 2, 3, 4, 8 and 12...

Spontaneous rupture of the aorta through an atherosclerotic lesion without preexisting aortic aneurysm, dissection, or history of trauma is very rare. Without prompt aortic repair, all cases result in sudden death with a definitive diagnosis made only intraoperatively or during autopsy. The phenomenon has been uniformly found in individuals with hypertension. The author reports a sudden unexpected death caused by spontaneous rupture of the ascending aorta in a 57-year-old man with a history of hypertension...

Respiratory syncytial virus (RSV)-bronchiolitis is a major cause of infant morbidity and mortality and a risk factor for subsequent asthma. We showed previously that toll-like receptor (TLR)7 in plasmacytoid dendritic cells (pDCs) is critical for protection against bronchiolitis and asthma in mice infected with pneumonia virus of mice (PVM), the mouse homolog of RSV. This lack of redundancy was unexpected as interferon-β promotor stimulator-1 (IPS-1) signalling, downstream of RIG-I-like receptor (RLR) and not TLR7 activation, contributes to host defence in hRSV-inoculated adult mice...

The diagnosis of cutaneous melanoma in situ, considered to have excellent prognosis, has been increasingly frequent, with rare isolated reports of cutaneous melanoma in situ presenting recurrence, metastasis, and death. No specific study is found in the literature about these lesions of unexpected behavior. We describe the demographic and histopathological findings of 448 cases of cutaneous melanoma in situ in 369 patients, emphasizing the prognostic criteria of those with unfavorable outcomes, corresponding to 9 cases in which regression had no significant role...

Sudden cardiac death in the young (SCDY) is always a devastating event. The death is sudden and unexpected and often in a person who was thought to be healthy. In recent years our understanding of these tragic events have drastically improved; 10-20years ago we did not know how often SCD occurred in the young, and we had sparse knowledge on the role of inheritance. We have found that SCD corresponds to 7% of all deaths with an overall (highest possible) incidence rate of 2.8 per 100,000 person-years (autopsy rate of sudden death cases of 75%)...

We previously reported unexpected apoptosis-like cell death induced by nematocyst venom (NV) from Chrysaora helvola Brandt (C. helvola) jellyfish. To assess whether the pore formation mechanism underlay the action of NV, the change in cell membrane permeability was studied in both chicken erythrocytes and human CNE-2 cells. Initially, paradoxical results were derived from osmoprotectant protection assays. Polyethylene glycol (PEG)2000, which completely inhibited the NV induced hemolysis, failed to protect CNE-2 cells...

Caspases are at the core of executing apoptosis by orchestrating cellular destruction with proteolytic cascades. Caspase-mediated proteolysis also controls diverse nonlethal cellular activities such as proliferation, differentiation, cell fate decision, and cytoskeletal reorganization. During the last decade or so, genetic studies of Drosophila have contributed to our understanding of the in vivo mechanism of the non-apoptotic cellular responses in developmental contexts. Furthermore, recent studies using C...

Disseminated necrotizing leukoencephalopathy (DNL) is characterized by multiple microscopic foci of white matter necrosis. DNL was initially thought to be exclusively associated with immunosuppression conditions but it has been recently described in immunocompetent patients in septic shock. A 90-year-old immunocompetent woman with no previous neurological impairment presented with septic shock and drowsiness that responded well to therapy with clinical improvement and a full neurological recovery. Unexpectedly deterioration with progression to coma occurred...

Choline alfoscerate (α-GPC) and Cytidine 5'-diphosphocholine (CDP-Choline) are both acetylcholine precursors and are considered to act as pro-cholinergic nootropic agents. Acetylcholine precursors have also recently found frequent use in the neurology clinic. Stroke and many types of dementia have been shown to respond favorably after treatment with these agents, not only in terms of cognitive dysfunction but also behavioral and psychological symptoms. The primary mechanisms of Acetylcholine precursors are the following: 1) Acetylcholine precursors themselves are used in the biosynthesis of acetylcholine and 2) byproducts like glycerophosphate have protective functions for neuronal phospholipids...

Study Objectives: Sudden unexpected death during sleep (SUDS) is the most common cause of death in patients with familial dysautonomia, an autosomal recessive disease characterized by sensory and autonomic dysfunction. It remains unknown what causes SUDS in these patients and who is at highest risk. We tested the hypothesis that SUDS in FD is linked to sleep-disordered breathing. Methods: We retrospectively identified patients with familial dysautonomia who died suddenly and unexpectedly during sleep and had undergone polysomnography within the 18-month period prior to death...

Existing epidemiological research on traffic largely neglects localized fluctuations. We leveraged finely-resolved congestion data to investigate short-term associations with mortality in near-road communities. We identified all non-accidental, cardiovascular, cerebrovascular, and respiratory deaths (2009-2013) within 1 km of a Puget Sound highway. Using a case-crossover design, we examined the association between congestion 0-150, 151-300, and 301-1000 m upwind of a decedent's home and mortality, adjusting for meteorology, holidays, and flu...

The occurrence of an unexpected sudden death puts the witnesses of this event in a situation of high emotional impact. The benefit to allow the families of victims to dispense the first resuscitation techniques has been emphasized. However, little data exist on the emotional impact of a cardio-respiratory arrest outside the hospital on the witness, who is often a close family member. Recently, we investigated the presence of psychological distress and the factors influencing it, in the active practice of basic resuscitation gestures by the witnesses guided by the operator 112...

A 77-year-old man with high-grade fever, progressive renal dysfunction, high serum level of C-reactive protein and positive serum myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) was diagnosed with microscopic polyangiitis with rapidly progressive glomerulonephritis, and remission induction treatment with glucocorticoids and intravenous cyclophosphamide was initiated. Although his general condition improved in a short time, intracerebral hemorrhage occurred 12 days after the initiation of treatment and emergent hematoma evacuation was performed...

The murine EL4 tumor model is an established in vivo apoptosis model for the investigation of novel cancer imaging agents and immunological treatments due to the rapid and significant response of the EL4 tumors to cyclophosphamide and etoposide combination chemotherapy. Despite the utility of this model system in cancer research little is known regarding the molecular details of the in vivo tumor cell death. Here we report the first in-depth quantitative proteomic analysis of the changes that occur in these tumors upon cyclophosphamide and etoposide treatment in vivo...

In 1710, the surgeon Pierre Dionis publishes a Dissertation on sudden death. Echoing and expanding the work of his Roman colleague Jean Marie Lancisi, he describes and analyzes dozens of cases of sudden death observed by him. A large number of cases was followed by autopsies allowing clinicopathological confrontation. Are proposed causes of death (pulmonary embolism, myocardial infarction, hemorrhagic stroke, arterial rupture, etc.), pathophysiological mechanisms based on the ancient theory of humors, and preventive actions to avoid these unexpected deaths...
