Code status orders in hospitalized patients with COVID-19.

Background: The COVID-19 pandemic created complex challenges regarding the timing and appropriateness of do-not-attempt cardiopulmonary resuscitation (DNACPR) and/or Do Not Intubate (DNI) code status orders. This paper sought to determine differences in utilization of DNACPR and/or DNI orders during different time periods of the COVID-19 pandemic, including prevalence, predictors, timing, and outcomes associated with having a documented DNACPR and/or DNI order in hospitalized patients with COVID-19. Methods: A cohort study of hospitalized patients with COVID-19 at two hospitals located in the Midwest. DNACPR code status orders including, DNI orders, demographics, labs, COVID-19 treatments, clinical interventions during hospitalization, and outcome measures including mortality, discharge disposition, and hospice utilization were collected. Patients were divided into two time periods (early and late) by timing of hospitalization during the first wave of the pandemic (March-October 2020). Results: Among 1375 hospitalized patients with COVID-19, 19% (n = 258) of all patients had a documented DNACPR and/or DNI order. In multivariable analysis, age (older) p =< 0.01, OR 1.12 and hospitalization early in the pandemic p = 0.01, OR 2.08, were associated with having a DNACPR order. Median day from DNACPR order to death varied between cohorts p => 0.01 (early cohort 5 days versus late cohort 2 days). In-hospital mortality did not differ between cohorts among patients with DNACPR orders, p = 0.80. Conclusions: There was a higher prevalence of DNACPR and/or DNI orders and these orders were written earlier in the hospital course for patients hospitalized early in the pandemic versus later despite similarities in clinical characteristics and medical interventions. Changes in clinical care between cohorts may be due to fear of resource shortages and changes in knowledge about COVID-19.

Monoclonal antibody generated against Nile tilapia (Oreochromis niloticus) IgT heavy chain using a peptide-based strategy.

Teleost IgT/Z plays a principal role in the defense mechanisms against infectious agents in the mucosal compartments and in systemic immunity. Previously, Nile tilapia (Oreochromis niloticus) IgT was discovered and characterized at transcription level. In this work, we generated a monoclonal antibody (mAb) that specifically recognized the Nile tilapia IgT. BALB/c mice were immunized with three synthetic peptides conjugated to KLH. The sequences of these peptides derived from the constant region of the Nile tilapia IgT heavy chain. ELISA and Western blotting confirmed the specificity of the polyclonal sera and the culture supernatant from a positive hybridoma clone. We observed immunoreactivity against a recombinant IgT fragment and native IgT in skin mucus. The anti-IgT mAb did not cross-react with purified tilapia IgM. Direct ELISA analysis allowed the quantification of skin mucus IgM and IgT concentrations. Flow cytometry analysis revealed differences in the percentage of IgT+ B cell populations between juveniles and adults in peripheral blood, head kidney and spleen lymphocytes and among the tissues analyzed. For further validation of the anti-IgT mAb utility, a recombinant vaccine candidate against sea lice (TT-P0 Ls) was injected into juvenile tilapia. Direct ELISA results revealed a differential secretion of skin mucus IgT and IgM after immunostimulation. In addition, the percentages of IgT+ B cells were determined at 7 days after booster and ex-vivo stimulation by flow cytometry. This mAb constitutes an important immunological tool to study the biological function and structural characteristics of tilapia IgT.

Palliative and End-of-Life Care After Severe Stroke.

BACKGROUND AND OBJECTIVES: The distinct illness trajectory after acute ischemic stroke demands a better understanding of the utilization of palliative care consultations (PCC) for this patient cohort. This study sought to determine the prevalence, predictors, and outcomes associated with PCC for patients hospitalized with severe ischemic stroke. METHODS: This multicenter cohort study was conducted at four hospitals (2 comprehensive and 2 primary stroke centers) between January, 2016 and December, 2019. We included all patients with a discharge diagnosis of ischemic stroke and an initial National Institutes of Health Stroke Scale (NIHSS) of 10 or greater. We compared patient sociodemographic, clinical and care characteristics as well as hospital outcomes between patients who did and did not receive PCC. RESULTS: The study included 1297 patients hospitalized with severe ischemic stroke. PCC occurred for 20% of all patients and this proportion varied across institutions from 11.9% to 43%. Less than half (43%) of patients who died in the hospital. In multivaraible analysis, PCC was less likely in female patients (OR .76, 95% CI .59, .99, P=0.04) but more likely in patients with higher NIHSS (OR1.95, 95% CI 1,13, 3.37, P=0.02). Patients with PCC had higher rates of moving to a plan focused on comfort measures (CMO) (P<0.01) and removal of artificial nutrition as part of a move to CMO (P<0.01). In a sub analysis of patients who died in the hospital and received PCC, patients who died on or before hospital day 3 were less likely to receive PCC than patients who died on or after hospital day 4 (24% v. 51%) (P=<0.01). CONCLUSIONS: Most patients with severe stroke do not receive PCC, even among those who experience in-hospital death. The results of this study indicate there are missed opportunities for PCC to help reduce suffering after severe stroke.

National Institutes of Health Stroke Scale (NIHSS) scoring inconsistencies between neurologists and emergency room nurses.

Background: Little is known about the consistency of initial NIHSS scores between neurologists and RNs in clinical practice. Methods: A cohort study of patients with a code stroke was conducted at an urban academic Primary Stroke Center in the Midwest between January 1, 2018, and December 31, 2019 to determine consistency in National Institutes of Health Stroke Scale Scores (NIHSS) between neurologists and registered nurses (RNs). Results: Among the 438 patients included in this study 65.3% (n = 286) of neurologist-RN NIHSS scoring pairs had congruent scores. One-in-three, (34.7%, n = 152) of neurologist-RN NIHSS scoring pairs had a clinically meaningful scoring difference of two points or greater. Higher NIHSS (p ≤ 0.01) and aphasia (p ≤ 0.01) were each associated with incongruent scoring between neurologist and emergency room RN pairs. Conclusions: One-in-three initial NIHSS assessed by both a neurologist and RN had a clinically meaningful score difference between providers. More severe stroke, as indicated by a higher NIHSS was associated with scoring inconsistency between neurologist-RN pairs. Subjective scoring measures, especially those involving a patient having aphasia, was associated with greater score incongruency. Score differences may be attributed to differences in NIHSS training requirements between neurologists and RNs.

Medical decision making about long-term artificial nutrition after severe stroke: a case report.

Choosing to use a percutaneous endoscopic gastrostomy (PEG tube) for long term artificial nutrition in the setting of inadequate oral intake after stroke is complex because the decision must be made in a relatively short amount of time and prognosis is often uncertain. This case study utilized interviews with attending and resident neurologists, and surrogate medical decision makers in order to examine how neurologists and surrogate medical decision makers approached the decision to either receive a PEG tube or pursue comfort measures after severe stroke in two patients. Although these two patients presented with similar clinical characteristics and faced similar medical decisions, different decisions regarding PEG tube placement were made. Major challenges included physicians who did not agree on prognosis and surrogates who did not agree on whether to place a PEG tube. These cases demonstrate the importance of the role of the surrogate medical decision maker and the necessity of physicians and surrogate medical decision makers approaching the complex decision of PEG tube placement after stroke together. Additionally, these cases highlight the differing views on what defines a good quality of life and show the vital importance of high-quality goals of care conversations about prognosis and quality of life when deciding whether to place a PEG tube after severe stroke.

Indiana Medical Resident's Knowledge of Surrogate Decision Making Laws.

INTRODUCTION: During the care of incapacitated patients, physicians, and medical residents discuss treatment options and gain consent to treat through healthcare surrogates. The purpose of this study is to ascertain medical residents' knowledge of healthcare consent laws, application during clinical practice, and appraise the education residents received regarding surrogate decision making laws. METHODS: Beginning in February of 2018, 35 of 113 medical residents working with patients within Indiana completed a survey. The survey explored medical residents' knowledge of health care surrogate consent laws utilized in Indiana hospitals and Veterans Affairs (VA) hospitals via clinical vignettes. RESULTS: Only 22.9% of medical residents knew the default state law in Indiana did not have a hierarchy for settling disputes among surrogates. Medical residents correctly identified which family members could participate in medical decisions 86% of the time. Under the Veterans Affairs surrogate law, medical residents correctly identified appropriate family members or friends 50% of the time and incorrectly acknowledged the chief decision makers during a dispute 30% of the time. All medical residents report only having little or some knowledge of surrogate decision making laws with only 43% having remembered receiving surrogate decision making training during their residency. CONCLUSIONS: These findings demonstrate that medical residents lack understanding of surrogate decision making laws. In order to ensure medical decisions are made by the appropriate surrogates and patient autonomy is upheld, an educational intervention is required to train medical residents about surrogate decision making laws and how they are used in clinical practice.
