Hanna Grol-Prokopczyk
Existing estimates of sociodemographic disparities in chronic pain in the United States are based on cross-sectional data, often treat pain as a binary construct, and rarely test for nonresponse or other types of bias. This study uses 7 biennial waves of national data from the Health and Retirement Study (1998-2010; n = 19,776) to describe long-term pain disparities among older (age 51+) American adults. It also investigates whether pain severity, reporting heterogeneity, survey nonresponse, and/or mortality selection might bias estimates of social disparities in pain...

Neuroplasticity is not only shaped by learning and memory but is also a mediator of responses to neuron attrition and injury (compensatory plasticity). As an ongoing process it reacts to neuronal cell activity and injury, death, and genesis, which encompasses the modulation of structural and functional processes of axons, dendrites, and synapses. The range of structural elements that comprise plasticity includes long-term potentiation (a cellular correlate of learning and memory), synaptic efficacy and remodelling, synaptogenesis, axonal sprouting and dendritic remodelling, and neurogenesis and recruitment...

BACKGROUND AND OBJECTIVES: Although there has recently been significant debate regarding the importance of disclosing the risk of SUDEP, professional societies and clinical practice guidelines currently recommend that the risk of SUDEP be disclosed as part of a comprehensive epilepsy education program. Therefore, the primary aim of the present study was to examine whether healthcare providers treating pediatric patients with epilepsy in Italy would disclose the risk of SUDEP to the parents of children with epilepsy...

OBJECTIVE: To seek a neuropathologic signature of sudden unexpected death in epilepsy (SUDEP) in a postmortem cohort by use of immunohistochemistry for specific markers of inflammation, gliosis, acute neuronal injury due to hypoxia, and blood-brain barrier (BBB) disruption, enabling the generation of hypotheses about potential mechanisms of death in SUDEP. METHODS: Using immunohistochemistry, we investigated the expression of 6 markers (CD163, human leukocyte antigen-antigen D related, glial fibrillary acid protein, hypoxia-inducible factor-1α [HIF-1α], immunoglobulin G, and albumin) in the hippocampus, amygdala, and medulla in 58 postmortem cases: 28 SUDEP (definite and probable), 12 epilepsy controls, and 18 nonepileptic sudden death controls...

Crimean-Congo hemorrhagic fever (CCHF) is a tick borne viral disease which can also be transmitted by direct contact with blood or tissue specimens of infected animals or humans. We present a fatal case of CCHF, who was diagnosed after death, and describe the post-exposure management plan for the health care workers (HCWs) involved in her care. In total of 52 HCWs were involved in the patient's care and they were stratified into risk groups. Overall, 20 HCWs were grouped in high and intermediate risk groups, including the HCW with needle stick injury...

Bedsharing is associated with both increased breastfeeding and increased risk of sudden and unexpected infant deaths. The objective was to determine impact of sleep location and counseling about sleep location on breastfeeding exclusivity and duration in African-Americans. 1194 mothers of newborns were randomized to receive messaging emphasizing either safe sleep practices to reduce SIDS risk or safe sleep practices to prevent SIDS/suffocation. Mothers completed four interviews in the 6 months after delivery...

The discovery that central nervous system (CNS)-targeted autoreactive T cells required a process of licensing in the lung revealed an unexpected relationship between these organs. The clinical and immunological significance of this finding is bidirectional in that it showed not only a mechanism by which T cells become pathogenic before entering the CNS, but also the potential for this process to influence lung immunity as well. Epidemiological studies have shown that people with multiple sclerosis (MS) suffer from increased morbidity and mortality from infectious diseases, independent of immunosuppressive therapies...

Hearing impairments are the most common symptom of congenital defects, and they generally remain intractable to treatment. Pendred syndrome, the most frequent syndromic form of hereditary hearing loss, is associated with mutations in the anion exchanger pendrin. Loss of pendrin function as an anion exchanger is thought to be causative, but rodent models do not exhibit progressive deafness. Here, we report a degenerative phenotype exhibiting mutant pendrin aggregates and increased susceptibility to cellular stresses in cochlear epithelial cells induced from patient-derived induced pluripotent stem cells (iPSCs)...

INTRODUCTION: Autopsy aids to the knowledge of pathology by unveiling the rare lesions which are a source of learning from a pathologist's perspective Some of them are only diagnosed at autopsy as they do not cause any functional derangement. This study emphasizes the various incidental lesions which otherwise would have been unnoticed during a person's life. AIM: The aim of this study was to determine the spectrum of histopathological findings including neoplastic lesions related or unrelated to the cause of death...

OBJECTIVES: To compare an indigenous sleep device (wahakura) for infants at high risk for sudden unexpected death with a bassinet, for measures of infant sleep position, head covering, breastfeeding, bed-sharing, and maternal sleep and fatigue. METHODS: A total of 200 mainly Māori pregnant women were recruited from deprived areas of New Zealand. They were randomized to receive a bassinet or wahakura and asked to sleep the infant in this device from birth. Questionnaires at 1, 3, and 6 months and an overnight infrared video in the home at 1 month were completed...

Sudden unexpected death in epilepsy (SUDEP) is a major cause of mortality in young patients with epilepsy (PWE). Although its mechanisms are still poorly understood, they may include cardiorespiratory dysfunction. Standard 12-lead electrocardiograms (ECGs) were obtained from 62 consecutive patients (aged 18-66y) with a definite diagnosis of epilepsy, without seizures at the day of ECG, and 57 healthy controls matched for sex, age and body mass index (BMI). All ECGs were evaluated by a blinded board-certified cardiologist...

: Despite considerable research to uncover them, the anatomic and neuropathologic correlates of memory impairment in dementia with Lewy bodies (DLB) remain unclear. While some studies have implicated Lewy bodies in the neocortex, others have pointed to α-synuclein pathology in the hippocampus. We systematically examined hippocampal Lewy pathology and its distribution in hippocampal subfields in 95 clinically and neuropathologically characterized human cases of DLB, finding that α-synuclein pathology was highest in two hippocampal-related subregions: the CA2 subfield and the entorhinal cortex (EC)...

PURPOSE: The medical emergency team (MET) can be activated anytime and anywhere in a hospital. We hypothesized the timing and location of MET activation are associated with seriousness of outcome. MATERIALS AND METHODS: We tested for an association of clinical outcomes with timing and location using a university hospital cohort in Japan (n = 328). The primary outcome was short-term serious outcome (unplanned ICU admission after MET activation or death at scene)...

Sudden infant death syndrome (SIDS) is a leading cause of death in infants, although the mechanisms leading to death remain unclear. Multiple theories have emerged over time, with one of the most influential hypotheses being the triple risk model. This model, first devised in 1972 and later revised in 1994 by Filiano and Kinney, is still widely used in assisting with conceptualising and understanding sudden death in infancy. This model has evolved over time, with each version stressing that SIDS is likely to occur when certain risk factors coincide, suggesting that the lethal mechanisms in SIDS are likely to be multifactorial...

Ictal tachycardia and bradycardia are common arrhythmias; however, ictal sinus pause and asystole are rare. Ictal arrhythmia is mostly reported in adults with temporal lobe epilepsy. Recently, ictal arrhythmia was recognized as a major warning sign of sudden unexpected death in epilepsy. We present an interesting case of a child with ictal sinus pause and asystole. A 27-month-old girl was hospitalized due to 5 episodes of convulsions during the past 2 days. Results of routine electroencephalography (EEG) were normal, but she experienced brief generalized tonic seizure for 3 days...

PURPOSE OF REVIEW: It is recognized that death is inevitable but rarely are we prepared for the death of significant persons in our lives. Sudden death is by its nature unexpected and thus shocking for family members and friends of the decedent. Sudden deaths have customarily been divided into four categories based on the cause of death, including natural, accidental, suicidal, or homicidal (NASH) deaths. Supporting the suddenly bereaved can be stressful, for both novice and experienced professionals; this review provides information important to healthcare professionals (HCP) who are often in a position to support family members after a sudden death...

Postmortem increase in body core temperature is a well-known phenomenon in forensic practice. Despite this, cases of reliably documented postmortem hyperthermia are rarely reported in the forensic literature, and it is still not clear how frequently postmortem hyperthermia occurs and in which cases we may it predict. In routine forensic practice, the standard course of body cooling is expected, and the prediction of normal body core temperature in the time of death is used for back-calculating the time of death by Henssge method...

The opioid epidemic has become a national public health and safety problem affecting both adults and adolescents. There is little doubt that this epidemic is rooted in the need for pain control after surgery and that orthopedic surgeons have in part contributed to opioid overprescription. Indeed, opioid abuse, misuse, and diversion are associated with increased hospitalizations, emergency department visits, and associated health care costs. In addition, postoperative exposure to opioids correlates with long-term use and abuse...

Hepatocellular carcinoma (HCC) is a leading cause of cancer deaths, but its molecular heterogeneity hampers the design of targeted therapies. Currently, the only therapeutic option for advanced HCC is Sorafenib, an inhibitor whose targets include RAF. Unexpectedly, RAF1 expression is reduced in human HCC samples. Modelling RAF1 downregulation by RNAi increases the proliferation of human HCC lines in xenografts and in culture; furthermore, RAF1 ablation promotes chemical hepatocarcinogenesis and the proliferation of cultured (pre)malignant mouse hepatocytes...
