INTRODUCTION: Hodgkin lymphoma (HL) is one of the most common types of cancers of the lymphatic system. The currently available therapies enable a cure in approximately 80-85% of treated patients. However, the cardiotoxicity of HL treatment has become a major cause of morbidity and mortality in survivors mainly related to the use of anthracycline. CASE REPORT: An HL, staged IIIB, was diagnosed in a 60-year-old man with no cardiovascular disease. During the first cycle of ABVD chemotherapy (Adriamycin; bleomycin; vinblastine; dacarbazine), near the end of the dacarbazine infusion, the patient presented a sudden cardiogenic shock characterized by a severe left ventricular systolic dysfunction...

The depressive state has been characterised as one of elevated inflammation, changed cardiovascular parameters and a deranged metabolic situation all of which holds promise for a better understanding and handling of treatment-resistance in affective disorders as well as for future developments in treatment algorithms. In this context several biomarkers are differentially regulated by antidepressant treatment and connected to metabolic, inflammatory, cardiovascular and apoptotic components of the pathophysiology, i...

BACKGROUND: Sofosbuvir plus ribavirin (RBV) therapy showed higher sustained virological response at 12 weeks after treatment (SVR12) than pegylated interferon (peg-IFN) plus RBV; however, liver function, fibrosis, and hepatocellular carcinoma markers have not been assessed so far. SUMMARY: Patients (n = 21) receiving Sofosbuvir plus RBV and those (n = 24) receiving peg-IFN plus RBV were enrolled in this study. Changes in alanine aminotransferase (ALT) and α-fetoprotein (AFP) levels, platelet (PLT) counts, FIB-4, and aspartate aminotransferase-to-platelet ratio index (APRI) in both groups were assessed in patients achieving SVR12...

BACKGROUND: Interictal epileptiform discharges are an important biomarker for localization of focal epilepsy, especially in patients who undergo chronic intracranial monitoring. Manual detection of these pathophysiological events is cumbersome, but is still superior to current rule-based approaches in most automated algorithms. OBJECTIVE: To develop an unsupervised machine-learning algorithm for the improved, automated detection and localization of interictal epileptiform discharges based on spatiotemporal pattern recognition...

Inherited mitochondrial optic neuropathies, such as Leber's hereditary optic neuropathy (LHON) and Autosomal dominant optic atrophy (ADOA) are caused by mutant mitochondrial proteins that lead to defects in mitochondrial complex 1-driven ATP synthesis, and cause specific retinal ganglion cell (RGC) loss. Complex 1 defects also occur in patients with primary open angle glaucoma (POAG), in which there is specific RGC loss. The treatment of mitochondrial optic neuropathy in the US is only supportive. The Ndufs4 knockout (Ndufs4 KO) mouse is a mitochondrial complex 1-deficient model that leads to RGC loss and rapid vision loss and allows for streamlined testing of potential therapeutics...

Genetic studies point to a major role of de novo mutations in neurodevelopmental disorders of intellectual disability, autism spectrum disorders, and epileptic encephalopathy. The STXBP1 gene encodes the syntaxin-binding protein 1 (Munc18-1) that critically controls synaptic vesicle exocytosis and synaptic transmission. This gene harbors a high frequency of de novo mutations, which may play roles in these neurodevelopmental disorders. However, the system and behavioral-level pathophysiological changes caused by these genetic defects remain poorly understood...

Almost 10% of patients with Crest syndrome associated with severe gastroesophageal reflux and 5-10% of patients with failed cardiomyotomy for achalasia present with cardial or distal esophageal organic stricture. Some of these cases are poor risk patients for surgery and therefore the surgeon must offer a safe procedure with low morbimortality, keeping in mind the pathophysiological motor pattern of these patients.In order to treat the stricture to improve the esophageal transit we treated patients with esophagocardioplasty associated with vagotomy-antrectomy and Roux-en-Y gastrojejunostomy, thereby avoiding the potential acid or biliary reflux in poor risk patients in whom esophagectomy would be a very deleterious procedure...

Maintaining an optimal blood pressure (BP) during shock is a fundamental tenet of critical care. Optimal BP targets maybe different for different patients. In current practice, too often, uniform BP targets are pursued which may result in inadvertently accepting a degree of untreated relative hypotension i.e., the deficit between patients' usual pre-morbid basal BP and the achieved BP, during vasopressor support. Relative hypotension is a common but an under-recognized and an under-treated sign among patients with potential shock state...

PURPOSE OF REVIEW: Most primary immunodeficiencies described since 1952 were associated with loss-of-function defects. With the advent and popularization of unbiased next-generation sequencing diagnostic approaches followed by functional validation techniques, many gain-of-function mutations leading to immunodeficiency have also been identified. This review highlights the updates on pathophysiology mechanisms and new therapeutic approaches involving primary immunodeficiencies because of gain-of-function mutations...

Our understanding of the role of oxygen in cell physiology has evolved from its long-recognized importance as an essential factor in oxidative metabolism to its recognition as an important player in cell signaling. With regard to the latter, oxygen is needed for the generation of reactive oxygen species (ROS), which regulate a number of different cellular functions including differentiation, proliferation, apoptosis, migration, and contraction. Data specifically concerning the role of ROS-dependent signaling in cutaneous wound repair are very limited, especially regarding wound contraction...

This paper presents diagnostic criteria for persistent postural-perceptual dizziness (PPPD) to be included in the International Classification of Vestibular Disorders (ICVD). The term PPPD is new, but the disorder is not. Its diagnostic criteria were derived by expert consensus from an exhaustive review of 30 years of research on phobic postural vertigo, space-motion discomfort, visual vertigo, and chronic subjective dizziness. PPPD manifests with one or more symptoms of dizziness, unsteadiness, or non-spinning vertigo that are present on most days for three months or more and are exacerbated by upright posture, active or passive movement, and exposure to moving or complex visual stimuli...

Muscle nicotinic acetylcholine receptor (nAChR) mutations can lead to altered channel kinetics and neuromuscular junction degeneration, a neurodegenerative disorder collectively known as slow-channel congenital myasthenic syndrome (SCCMS). A multivariate analysis using running wheels was used to generate activity profiles for a variety of SCCMS models, uncovering unique locomotor patterns for the different nAChR mutants. Particularly, the αL251T and ɛL269F mutations exhibit decreased event distance, duration, and velocity over a period of 24 hours...

ADAM10 is the α-secretase that cleaves amyloid-β protein precursor in the non-amyloidogenic pathway in Alzheimer's disease (AD) and is known to be regulated by different microRNAs (miRNAs), which are post-transcriptional regulators related to several biological and pathological processes, including AD. Here we proposed to explore and validate miRNAs that have direct or indirect relations to the AD pathophysiology and ADAM10 gene. Approximately 700 miRNAs were analyzed and 21 differentially expressed miRNAs were validated in a sample of 21 AD subjects and 17 cognitively healthy matched controls...

The identification of early biological changes associated with the psychotic disorder (PD) is important as it may provide clues to the underlying pathophysiological mechanisms. We undertook the first proteomic profiling of blood plasma samples of children who later develop a PD. Participants were recruited from the UK Avon Longitudinal Study of Parents and Children (ALSPAC) cohort who also participated in psychiatric assessment interviews at age 18. Protein expression levels at age 11 were compared between individuals who developed PD at age 18 (n = 37) with population-based age-matched controls (n = 38)...

Mismatch negativity (MMN) and P300 event-related potential (ERP) reductions in schizophrenia (SZ) reflect preattentive and attention-mediated auditory processing deficits, respectively. Although both have been linked to cognitive deficits in SZ, their relative contributions to real-world functioning are unclear. We sought to determine the functional significance of disrupted auditory processing in SZ by examining MMN and P300 in typically disabled low-functioning patients and in patients with high levels of independent role functioning...

Deficit schizophrenia (DS), characterized by primary and enduring negative symptoms, has been considered as a pathophysiologically distinct schizophrenic subgroup. Neuroimaging characteristics of DS, especially functional brain network architecture, remain largely unknown. Resting-state functional magnetic resonance imaging and graph theory approaches were employed to investigate the topological organization of whole-brain functional networks of 114 male participants including 33 DS, 41 non-deficit schizophrenia (NDS) and 40 healthy controls (HCs)...

Fear generalization is a prominent feature of anxiety disorders and post-traumatic stress disorder. It is defined as enhanced fear responding to a stimulus that bears similarities, but is not identical to a threatening stimulus. Pattern separation, a hippocampal-dependent process, is critical for stimulus discrimination; it transforms similar experiences or events into non-overlapping representations. The current study is the first in humans to investigate the extent to which fear generalization relies on behavioral pattern separation abilities...
