Pathways to Neuropalliative Care Practice.

As neuropalliative care is better recognized and more widely utilized, there is as great a need for clinicians trained in the field as there is for disease-specific symptom management, advance care planning, and end-of-life care. In this manuscript, we describe potential career trajectories in neuropalliative care. For clinicians, this includes educational and training opportunities within primary neuropalliative care (integrating palliative care principles into usual neurology practice), specialty neuropalliative care (completing a hospice and palliative medicine fellowship), and hospice. We also describe considerations for establishing new clinical neuropalliative practices and highlight neuropalliative education and research as key areas for advancing the field.

Jugular Foramen Syndrome Caused by Varicella Zoster Virus Infection.

Jugular foramen syndrome (JFS) is a lower cranial neuropathy syndrome characterized by dysphonia and dysphagia. The syndrome is caused by dysfunction of the glossopharyngeal, vagus, and spinal accessory nerves at the level of the pars nervosa and pars vascularis within the jugular foramen. There are numerous etiologies for JFS, including malignancy, trauma, vascular, and infection. Here, we present the case of a healthy adult man who developed JFS secondary to an atypical presentation of Varicella Zoster meningitis, and was promptly diagnosed and treated with rapid symptom resolution. We diagnosed the patient using specialized skull-based imaging which detailed the jugular foramen, as well as CSF analysis. This case highlights the clinical value of detailed structural evaluation, consideration for infection in the absence of systemic symptoms, and favorable outcomes following early identification and treatment.

What's in the Sauce? The Specific Benefits of Palliative Care for Parkinson's Disease.

CONTEXT: Increasing evidence demonstrates the benefits of palliative care among individuals with Parkinson's disease and related disorders (PDRD), but the critical components that contribute to therapeutic effects are not well understood. OBJECTIVES: To determine the specific items most responsive to a palliative care intervention in PDRD and identify key correlates of improvement in patient and care partner outcomes. METHODS: The main trial was a pragmatic comparative effectiveness trial of outpatient integrated palliative care compared to standard care among participants with PDRD (NCT02533921), showing significantly higher patient QOL at six months and lower care partner burden at 12 months. We used longitudinal regression models to analyze changes in subdomains of patient QOL and care partner burden and Spearman correlations to evaluate key correlates of change scores in patient and care partner outcomes. We performed a secondary analysis of data from 210 patients and 175 care partners. RESULTS: Compared to controls, patients in the intervention reported greater improvement in perceptions of the "self as a whole" at six months (coeff = 0.22, P < 0.05) and care partners reported greater reduction in stress, anger, and loss of control at 12 months (coeff = -.40, -0.25, -0.31, P < 0.05). Positive change in numerous patient non-motor symptoms and grief correlated with improved patient QOL, reduced patient anxiety, and increased care partner spirituality. Alleviation of care partner anxiety and depression correlated with reduced care partner burden. CONCLUSION: Specific benefits of an integrated palliative approach in PDRD include improvement in patient holistic self-impressions, care partner self-efficacy, and non-motor symptoms.

High-mobility group box-1 translocation and release after hypoxic ischemic brain injury in neonatal rats.

Inflammation contributes to neonatal brain injury. Pro-inflammatory cytokines represent key inflammatory meditators in neonatal hypoxic-ischemic (HI) brain injury. The high mobility group box-1 (HMGB1) protein is a nuclear protein with pro-inflammatory cytokine properties when it is translocated from the nucleus and released extracellularly after stroke in adult rodents. We have previously shown that HMGB1 is translocated from the nucleus to cytosolic compartment after ischemic brain injury in fetal sheep. In the current study, we utilized the Rice-Vannucci model to investigate the time course of HMGB1 translocation and release after HI injury in neonatal rats. HMGB1 was located in cellular nuclei of brains from sham control rats. Nuclear to cytoplasmic translocation of HMGB1 was detected in the ipsilateral-HI hemisphere as early as zero h after HI, and released extracellularly as early as 6 h after HI. Immunohistochemical double staining detected HMGB1 translocation mainly in neurons along with release from apoptotic cells after HI. Serum HMGB1 increased at 3 h and decreased by 24 h after HI. In addition, rat brains exposed to hypoxic injury alone also exhibited time dependent HMGB1 translocation at 3, 12 and 48 h after hypoxia. Consequently, HMGB1 responds similarly after HI injury in the brains of neonatal and adult subjects. We conclude that HMGB1 is sensitive early indicator of neonatal HI and hypoxic brain injury.

Perioperative Management of Sickle Cell Disease.

Over 30 million people worldwide have sickle cell disease (SCD). Emergent and non-emergent surgical procedures in SCD have been associated with relatively increased risks of peri-operative mortality, vaso-occlusive (painful) crisis, acute chest syndrome, post-operative infections, congestive heart failure, cerebrovascular accident and acute kidney injury. Pre-operative assessment must include a careful review of the patient's known crisis triggers, baseline hematologic profile, usual transfusion requirements, pre-existing organ dysfunction and opioid use. Use of preoperative blood transfusions should be selective and decisions individualized based on the baseline hemoglobin, surgical procedure and anticipated volume of blood loss. Intra- and post-operative management should focus on minimizing hypoxia, hypothermia, acidosis, and intravascular volume depletion. Pre- and post-operative incentive spirometry use should be encouraged.

HMGB1 Translocation After Ischemia in the Ovine Fetal Brain.

Inflammation contributes to the evolution of hypoxic-ischemic (HI) brain injury. High-mobility group box-1 (HMGB1) is a nuclear protein that is translocated from the nucleus and released after ischemia in adult rodents and thereby initiates inflammatory responses. However, there is very little information regarding the effects of HI on HMGB1 in immature brains. To investigate the effects of HI on HMGB1 in the term-equivalent fetal brain, ovine fetuses at 127 days gestation were studied after 30 minutes of carotid occlusion. Groups were sham-control and ischemia with 48 hours and ischemia with 72 hours of reperfusion. By immunohistochemistry, HMGB1 was found to be localized primarily in cell nuclei and partially in cytoplasmic compartments in the cerebral cortex of controls. Ischemia increased the area fraction of neuronal cells with cytoplasmic HMGB1 staining, and Western immunoblot revealed that cytosolic HMGB1 expression increased after ischemia (p < 0.05) and decreased in nuclei in ischemic versus the sham-control brains (p < 0.05). These data indicate that HMGB1 translocates from the nuclear to cytosolic compartments after ischemic brain injury in fetal sheep. This translocation may enable the action of HMGB1 as a proinflammatory cytokine that contributes to HI injury in the developing brain.
