Neurological Prognostication After Hypoglycemic Coma: Role of Clinical and EEG Findings.

BACKGROUND: Hypoglycemic coma (HC) is an uncommon but severe clinical condition associated with poor neurological outcome. There is a dearth of robust neurological prognostic factors after HC. On the other hand, there is an increasing body of literature on reliable prognostic markers in the postanoxic coma, a similar-albeit not identical-situation. The objective of this study was thus to investigate the use and predictive value of these markers in HC. METHODS: We conducted a retrospective, multicenter, cohort study within five centers of the Critical Care EEG Monitoring Research Consortium. We queried our electroencephalography (EEG) databases to identify all patients undergoing continuous EEG monitoring after admission to an intensive care unit with HC (defined as Glasgow Coma Scale < 8 on admission and a first blood glucose level < 50 mg/dL or not documented but in an obvious clinical context) between 01/01/2010 and 12/31/2020. We studied the association of findings at neurological examination (Glasgow Coma Scale motor subscale, pupillary light and corneal reflexes) and at continuous EEG monitoring(highly malignant patterns, reactivity, periodic discharges, seizures) with best neurological outcome within 3 months after hospital discharge, defined by the Cerebral Performance Category as favorable (1-3: recovery of consciousness) versus unfavorable (4-5: lack of recovery of consciousness). RESULTS: We identified 60 patients (30 [50%] women; age 62 [51-72] years). Thirty-one and 29 patients had a favorable and unfavorable outcome, respectively. The presence of pupillary reflexes (24 [100%] vs. 17 [81%]; p value 0.04) and a motor subscore > 2 (22 [92%] vs. 12 [63%]; p value 0.03) at 48-72 h were associated with a favorable outcome. A highly malignant EEG pattern was observed in 7 of 29 (24%) patients with unfavorable outcome versus 0 of 31 (0%) with favorable outcome, whereas the presence of EEG reactivity was observed in 28 of 31 (90%) patients with favorable outcome versus 13 of 29 (45%) with unfavorable outcome (p < 0.001 for comparison of all background categories). CONCLUSIONS: This preliminary study suggests that highly malignant EEG patterns might be reliable prognostic markers of unfavorable outcome after HC. Other EEG findings, including lack of EEG reactivity and seizures and clinical findings appear less accurate. These findings should be replicated in a larger multicenter prospective study.

Frequency of Withdrawal of Life-Sustaining Therapy for Perceived Poor Neurologic Prognosis.

To measure the frequency of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis among decedents in hospitals of different sizes and teaching statuses. DESIGN: We performed a multicenter, retrospective cohort study. SETTING: Four large teaching hospitals, four affiliated small teaching hospitals, and nine affiliated nonteaching hospitals in the United States. PATIENTS: We included a sample of all adult inpatient decedents between August 2017 and August 2019. MEASUREMENTS AND MAIN RESULTS: We reviewed inpatient notes and categorized the immediately preceding circumstances as withdrawal of life-sustaining therapy for perceived poor neurologic prognosis, withdrawal of life-sustaining therapy for nonneurologic reasons, limitations or withholding of life support or resuscitation, cardiac death despite full treatment, or brain death. Of 2,100 patients, median age was 71 years (interquartile range, 60-81 yr), median hospital length of stay was 5 days (interquartile range, 2-11 d), and 1,326 (63%) were treated at four large teaching hospitals. Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis occurred in 516 patients (25%) and was the sole contributing factor to death in 331 (15%). Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis was common in all hospitals: 30% of deaths at large teaching hospitals, 19% of deaths in small teaching hospitals, and 15% of deaths at nonteaching hospitals. Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis happened frequently across all hospital units. Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis contributed to one in 12 deaths in patients without a primary neurologic diagnosis. After accounting for patient and hospital characteristics, significant between-hospital variability in the odds of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis persisted. CONCLUSIONS: A quarter of inpatient deaths in this cohort occurred after withdrawal of life-sustaining therapy for perceived poor neurologic prognosis. The rate of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis occurred commonly in all type of hospital settings. We observed significant unexplained variation in the odds of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis across participating hospitals.

A patient perspective of complementary and integrative medicine (CIM) for migraine treatment: a social media survey.

To survey persons with migraine who use social media about Complementary and Integrative Medicine (CIM) for the treatment of migraine. BACKGROUND: CIM encompasses medical treatments that are not part of but are used in concert with mainstream medicine. Between 28 and 82% of people with migraine use non-drug approaches, and approximately 50% of people with migraine do not discuss non-drug treatments with their healthcare providers (HCPs). It is important for providers to be conversant with CIM treatments and the available evidence-based data. To further this effort, people with migraine were surveyed directly through social media to identify CIM practices in which they engage. METHODS: In collaboration with the American Migraine foundation (AMF) and Yakkety Yak, a digital marketing agency, we conducted a cross-sectional survey study. Participants were recruited from the Move Against Migraine (MAM) Facebook group which has 20,000+ members. The goals of the survey were to assess the attitudes toward CIM among this group, to identify which CIM modalities are being used and to determine what patients considered to be the most effective CIM modalities. While Yakkety Yak posted the survey link on the group page, the survey itself was hosted on Qualtrics, a confidential survey service. RESULTS: 372 MAM members (approximately 2%) responded to the questionnaire, of which 335 reported using CIM; between 114 and 139 (34-42%) found CIM modalities to be at least mildly effective. Of note, 164 (49%) reported using cannabis derivatives or cannabinoids, specifically with, 64/164 (39%) reporting that cannabis was not effective for them. CONCLUSIONS: This study provides an initial investigation into the demographic and practice patterns of migraine patients who use CIM. While this sampling may not reflect CIM use across all individuals with migraine, it does strongly suggest the need for better education on the role of, and evidence for, CIM among headache care providers, and the need to ask patients specifically about their use of and interest in CIM.

Management Strategies for Intracranial Pressure Crises in Subarachnoid Hemorrhage.

Objectives: Standard management strategies for lowering intracranial pressure (ICP) in traumatic brain injury has been well-studied, but the use of lesser known interventions for ICP in subarachnoid hemorrhage (SAH) remains elusive. Searches were performed in PubMed and EBSCO Host to identify best available evidence for evaluation and management of medically refractory ICP in SAH. The role of standard management strategies such as head elevation, hyperventilation, mannitol and hypertonic saline as well as lesser known management such as sodium bicarbonate, indomethacin, tromethamine, decompressive craniectomy, decompressive laparotomy, hypothermia, and barbiturate coma are reviewed. We also included dose concentrations, dose frequency, infusion volume, and infusion rate for these lesser known strategies. Nonetheless, there is still a gap in the evidence to recommend optimal dosing, timing and its role in the improvement of outcomes but early diagnosis and appropriate management reduce adverse outcomes.

Religion benefiting brain tumour patients: a qualitative study.

As the focus on modern neurosurgery has shifted to the realm of technological advancement, some patients and their loved ones still hold a strong faith in their religion to guide them through the process. This study aimed to determine whether religion as a coping mechanism was beneficial for patients before, during and after craniotomy. Qualitative case study methodology was used. Interviews were conducted with randomly selected 36 adult patients who underwent surgery for a benign or malignant brain tumour. Interviews were audio recorded and transcribed, and the data subjected to thematic analysis. Four overarching themes emerged from the data: (1) religion significantly benefited neurosurgical patients; (2) neurosurgical patients did not require a dedicated religious room in the hospital; (3) neurosurgical patients required religious resources such as leaders and/or groups; and (4) patients were not in favour of their physician engaging in the religious ritual. Most patients found religion to be an effective coping mechanism, offering them strength, comfort, and hope through the surgery. The findings from this study emphasize the need for including a "religious time-out" before and after surgery and the inclusion of religious leaders/groups for those in favour to ensure quality care and patient satisfaction.
