Early In-Bed Cycle Ergometry in Mechanically Ventilated Patients.

BACKGROUND: Critical illness requiring invasive mechanical ventilation can precipitate important functional disability, contributing to multidimensional morbidity following admission to an intensive care unit (ICU). Early in-bed cycle ergometry added to usual physiotherapy may mitigate ICU-acquired physical function impairment. METHODS: We randomly assigned 360 adult ICU patients undergoing invasive mechanical ventilation to receive 30 minutes of early in-bed Cycling + Usual physiotherapy (n=178) or Usual physiotherapy alone (n=182). The primary outcome was the Physical Function ICU Test-scored (PFIT-s) at 3 days after discharge from the ICU (the score ranges from 0 to 10, with higher scores indicating better function). RESULTS: Cycling began within a median (interquartile range) of 2 (1 to 3) days of starting mechanical ventilation; patients received 3 (2 to 5) cycling sessions for a mean (±standard deviation) of 27.2 ± 6.6 minutes. In both groups, patients started Usual physiotherapy within 2 (2 to 4) days of mechanical ventilation and received 4 (2 to 7) Usual physiotherapy sessions. The duration of Usual physiotherapy was 23.7 ± 15.1 minutes in the Cycling + Usual physiotherapy group and 29.1 ± 13.2 minutes in the Usual physiotherapy group. No serious adverse events occurred in either group. Among survivors, the PFIT-s at 3 days after discharge from the ICU was 7.7 ± 1.7 in the Cycling + Usual physiotherapy group and 7.5 ± 1.7 in the Usual physiotherapy group (absolute difference, 0.23 points; 95% confidence interval, -0.19 to 0.65; P=0.29). CONCLUSIONS: Among adults receiving mechanical ventilation in the ICU, adding early in-bed Cycling to usual physiotherapy did not improve physical function at 3 days after discharge from the ICU compared with Usual physiotherapy alone. Cycling did not cause any serious adverse events.

Severity-of-Illness Scores and Discharge Disposition in Patients Admitted to Long-Term Acute Care Hospitals.

BACKGROUND: After an intensive care unit (ICU) admission, nearly 20% of survivors of chronic critical illness require admission to a long-term acute care hospital (LTACH) for continued subspecialty care. The effect of the burden of medical comorbidities on discharge disposition after LTACH admission remains unclear. METHODS: A retrospective cohort study was performed involving patients with chronic critical illness who were discharged from the medical ICU and admitted to an LTACH between 2016 and 2018. The patients' Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA), Nutrition Risk in the Critically Ill (NUTRIC), and Charlson Comorbidity Index (CCI) scores at the time of LTACH admission were calculated from electronic medical records. The mean scores on each instrument were compared by discharge disposition. RESULTS: A total of 156 patients were admitted to the LTACH from the medical ICU between 2016 and 2018. They had a mean (SD) age of 61.5 (13.3) years, a mean (SD) body mass index of 28.1 (8.3), a median (IQR) ICU stay of 16.3 (1-108) days, and a median (IQR) LTACH stay of 38.2 (1-227) days. Patients who were discharged home had lower mean (SD) APACHE II (14.6 [5.0] vs 18.2 [5.4], P = .01), SOFA (3.3 [2.1] vs 4.6 [2.1], P = .03), NUTRIC (3.3 [1.4] vs 4.6 [1.4], P = .001), and CCI (4.3 [2.5] vs 6.1 [2.8], P = .02) scores on admission to the LTACH than those who were not discharged home. CONCLUSION: Severity-of-illness scores on admission to an LTACH can be used to predict patients' likelihood of being discharged home.

Critical Care Cycling to Improve Lower Extremity Strength (CYCLE): protocol for an international, multicentre randomised clinical trial of early in-bed cycling for mechanically ventilated patients.

INTRODUCTION: In-bed leg cycling with critically ill patients is a promising intervention aimed at minimising immobility, thus improving physical function following intensive care unit (ICU) discharge. We previously completed a pilot randomised controlled trial (RCT) which supported the feasibility of a large RCT. In this report, we describe the protocol for an international, multicentre RCT to determine the effectiveness of early in-bed cycling versus routine physiotherapy (PT) in critically ill, mechanically ventilated adults. METHODS AND ANALYSIS: We report a parallel group RCT of 360 patients in 17 medical-surgical ICUs and three countries. We include adults (≥18 years old), who could ambulate independently before their critical illness (with or without a gait aid), ≤4 days of invasive mechanical ventilation and ≤7 days ICU length of stay, and an expected additional 2-day ICU stay, and who do not fulfil any of the exclusion criteria. After obtaining informed consent, patients are randomised using a web-based, centralised system to either 30 min of in-bed cycling in addition to routine PT, 5 days per week, up to 28 days maximum, or routine PT alone. The primary outcome is the Physical Function ICU Test-scored (PFIT-s) at 3 days post-ICU discharge measured by assessors blinded to treatment allocation. Participants, ICU clinicians and research coordinators are not blinded to group assignment. Our sample size estimate was based on the identification of a 1-point mean difference in PFIT-s between groups. ETHICS AND DISSEMINATION: Critical Care Cycling to improve Lower Extremity (CYCLE) is approved by the Research Ethics Boards of all participating centres and Clinical Trials Ontario (Project 1345). We will disseminate trial results through publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT03471247 (Full RCT); NCT02377830 (CYCLE Vanguard 46 patient internal pilot).

Disseminated Cryptococcosis in an Immunocompromised Patient with Altered Mental Status and a Lung Nodule.

Introduction: Disseminated cryptococcosis is an opportunistic infection that commonly affects the central nervous and respiratory systems and is often fatal in immunocompromised host patients. Diagnosing disseminated cryptococcosis is challenging at times due to the nonspecific presentation, resulting in delayed treatment and increased mortality. Case presentation: A 48-year-old man presented with altered mental status and shortness of breath requiring intubation. Medical history was significant for rheumatoid arthritis, diabetes mellitus, chronic kidney disease, sarcoidosis, and polymyalgia rheumatica. Home medications included prednisone, methotrexate, and tocilizumab. Computed tomography chest revealed multifocal pneumonia with a cavitary nodule with halo sign. One week after extubation, the patient remained confused. Lumbar puncture (LP) was positive for Cryptococcus neoformans within 5 days. Bronchoalveolar lavage (BAL) yielded similar results on fungal culture one month later. Conclusion: An immunocompromised host patient who presents with altered mental status with concomitant lung nodules should have disseminated cryptococcosis as a differential diagnosis. CT chest commonly demonstrate peripheral lung nodules with cavitation, air bronchograms, halo sign, and/or enlarged mediastinal lymphadenopathy, as found in our patient. If the clinical suspicion for disseminated cryptococcosis is high, an LP should be performed, as BAL results may often be delayed since Cryptococcus grows slowly from the lungs. Empiric antifungals should be started immediately, given increased mortality if treatment is delayed.

A case of fatal disseminated adenovirus and drug-resistant Pneumocystis pneumonia in a patient who received chemotherapy for mantle cell lymphoma.

Adenovirus (ADV) may cause severe complications in hematopoietic stem cell transplant recipients, but disseminated ADV infections in patients who received chemotherapy alone for hematological malignancies are poorly understood due to the rarity of cases. Concomitant infection with Pneumocystis (PCP) is extremely rare. Despite being diagnostically challenging, a more specific workup needs to be initiated with a low threshold in patients who are exposed to agents with the potential to suppress T cells. We report a fatal case of disseminated ADV and drug-resistant PCP pneumonia in a patient with mantle cell lymphoma who had only received combination chemotherapy. A 75-year-old man who was diagnosed with mantle cell lymphoma 10 months prior was admitted for mild hypoxic respiratory failure. Bendamustine, Rituximab, Cytarabine regimen had resulted in complete remission of his lymphoma, with the last cycle of chemotherapy administered 3 months prior to admission. CT of the chest revealed ground-glass opacities concerning pneumonia. Initial laboratory tests were remarkable for mild leukopenia. The respiratory viral panel was only positive for ADV. He did not respond to empiric antibiotics for community-acquired pneumonia and Trimethoprim / Sulfamethoxazole given later for positive Beta D Glucan (BDG) suggestive of Pneumocystis pneumonia. Then, he developed hemorrhagic cystitis, followed by liver and renal function derangement that prompted checking serum ADV viral load by polymerase chain reaction (PCR). This test took 1 week to return, with a viral load of 50, 000 copies/mL suggesting disseminated ADV infection. Despite initiation of Cidofovir, multi-organ failure continued to progress, and the follow-up viral load had doubled on Day 2. The patient passed away the same day shortly after transition to comfort care. T cell suppression seems to be a risk factor for disseminated ADV disease. Clinicians may need to maintain a low threshold to send serum quantitative ADV PCR when symptoms are not improved by antimicrobial treatment for more conventional infections in patients who received agents that are known to suppress T cells, such as Bendamustine.

Guillain-Barre syndrome secondary to COVID-19 infection: A case report.

Guillain-Barre syndrome (GBS) is a rare autoimmune disease that often manifests as a post-viral complication. However, its association with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unclear. We present a rare case of GBS secondary to COVID-19 infection complicated by rapidly progressive sensorimotor deterioration resistant to plasma exchange therapy.

Smart Phone/Ecological Momentary Assessment of Sleep and Daytime Symptoms Among Older Adults With Insomnia.

OBJECTIVES: To employ smart phone/ecological momentary assessment (EMA) methods to evaluate the impact of insomnia on daytime symptoms among older adults. DESIGN: Prospective cohort study SETTING: Academic medical center PARTICIPANTS: Twenty-nine older adults with insomnia (M age = 67.5 ± 6.6 years, 69% women) and 34 healthy sleepers (M age = 70.4 ± 5.6 years, 65% women). MEASUREMENTS: Participants wore an actigraph, completed daily sleep diaries, and completed the Daytime Insomnia Symptoms Scale (DISS) via smart phone 4x/day for 2 weeks (i.e., 56 survey administrations across 14 days). RESULTS: Relative to healthy sleepers, older adults with insomnia demonstrated more severe insomnia symptoms in all DISS domains (alert cognition, positive mood, negative mood, and fatigue/sleepiness). A series of mixed model analyses were performed using the Benjamini-Hochberg procedure for correcting false discovery rate (BH-FDR) and an adjusted p-value <0.05. Among older adults with insomnia, all five prior-night sleep diary variables (sleep onset latency, wake after sleep onset, sleep efficiency, total sleep time, and sleep quality) were significantly associated with next-day insomnia symptoms (i.e., all four DISS domains). The median, first and third quintiles of the effect sizes (R2) of the association analyses were 0.031 (95% confidence interval (CI: [0.011,0.432]), 0.042(CI: [0.014,0.270]), 0.091 (CI:[0.014,0.324]). CONCLUSION: Results support the utility of smart phone/EMA assessment among older adults with insomnia. Clinical trials incorporating smart phone/EMA methods, including EMA as an outcome measure, are warranted.

Combining exercise, protein supplementation and electric stimulation to mitigate muscle wasting and improve outcomes for survivors of critical illness-The ExPrES study.

BACKGROUND: Neuromuscular electrical stimulation (NMES) with high protein supplementation (HPRO) to preserve muscle mass and function has not been assessed in ICU patients. We compared the effects of combining NMES and HPRO with mobility and strength rehabilitation (NMES+HPRO+PT) to standardized ICU care. OBJECTIVES: To assess the effectiveness of combined NMES+HPRO+PT in mitigating sarcopenia as evidenced by CT volume and cross-sectional area when compared to usual ICU care. Additionally, we assessed the effects of the combined therapy on select clinical outcomes, including nutritional status, nitrogen balance, delirium and days on mechanical ventilation. METHODS: Participants were randomized by computer generated assignments to receive either NMES+HPRO+PT or standard care. Over 14 days the standardized ICU care group (N = 23) received usual critical care and rehabilitation while the NMES+HPRO+PT group (N = 16) received 30 min neuromuscular electrical stimulation of quadriceps and dorsiflexors twice-daily for 10 days and mean 1.3 ± 0.4 g/kg body weight of high protein supplementation in addition to standard care. Nonresponsive participants received passive exercises and, once responsive, were encouraged to exercise actively. Primary outcome measures were muscle volume and cross-sectional area measured using CT-imaging. Secondary outcomes included nutritional status, nitrogen balance, delirium and days on mechanical ventilation. RESULTS: The NMES+HPRO+PT group (N = 16) lost less lower extremity muscle volume compared to the standard care group (N = 23) and had larger mean combined thigh cross-sectional area. The nitrogen balance remained negative in the standard care group, while positive on days 5, 9, and 14 in the NMES+HPRO+PT group. Standard care group participants experienced more delirium than the NMES+HPRO+PT group. No differences between groups when comparing length of stay or mechanical ventilation days. CONCLUSIONS: The combination of neuromuscular electrical stimulation, high protein supplementation and mobility and strength rehabilitation resulted in mitigation of lower extremity muscle loss and less delirium in mechanically ventilated ICU patients.

Spontaneous Oropharyngeal Hemorrhage Complicated by Cirrhosis, Resulting in Hemorrhagic Shock.

BACKGROUND Spontaneous oropharyngeal hemorrhage is rare and is often associated with other predisposing factors. This can result in hemodynamic instability in the presence of other bleeding sources. It is oftentimes difficult to diagnose due to its limitations to visual inspection of the oropharyngeal structures. It is commonly mistaken for hemoptysis or hematemesis upon initial evaluation. Trauma, infection, pulmonary pathologies (ie, lung cancer or tuberculosis), gastrointestinal pathologies (ie, esophageal/gastric varices, Mallory-Weiss tears, esophagitis), coagulopathies, medications, and prolonged intubation have been shown to increase the risk of oropharyngeal hemorrhage. CASE REPORT A 54-year-old man with a medical history of alcohol use disorder, liver cirrhosis, portal hypertension, and gastric varices presented with altered mental status. He was subsequently intubated for airway protection. Bleeding from the oropharynx was later found. Esophagogastroduodenoscopy (EGD) and bronchoscopy were unrevealing. Computed tomography angiography (CTA) of the head and neck revealed active bleeding of the right posterior pharyngeal artery, which was emergently embolized. Over the next few days, he continued to bleed from the oropharynx and became hemodynamically unstable. CTA abdomen showed bleeding from gastric varices and large-volume hemoperitoneum with multiple sources of active bleeding from the liver, duodenum, and jejunum. CONCLUSIONS We present a rare case of spontaneous oropharyngeal hemorrhage and gastric variceal bleeding resulting in hemorrhagic shock in a cirrhotic patient with multiple predisposing factors. If a patient presents with spontaneous oropharyngeal hemorrhage, clinicians should consider bleeding from the oropharynx if EGD and bronchoscopy are unrevealing. Thus, an emergent CTA of the head and neck should be strongly considered to further evaluate a potential source of active bleeding, as delayed diagnosis can be life-threatening.

Research interrupted: applying the CONSERVE 2021 Statement to a randomized trial of rehabilitation during critical illness affected by the COVID-19 pandemic.

RATIONALE: The COVID-19 pandemic disrupted non-COVID critical care trials globally as intensive care units (ICUs) prioritized patient care and COVID-specific research. The international randomized controlled trial CYCLE (Critical Care Cycling to Improve Lower Extremity Strength) was forced to halt recruitment at all sites in March 2020, creating immediate challenges. We applied the CONSERVE (CONSORT and SPIRIT Extension for RCTs Revised in Extenuating Circumstance) statement as a framework to report the impact of the pandemic on CYCLE and describe our mitigation approaches. METHODS: On March 23, 2020, the CYCLE Methods Centre distributed a standardized email to determine the number of patients still in-hospital and those requiring imminent 90-day endpoint assessments. We assessed protocol fidelity by documenting attempts to provide the in-hospital randomized intervention (cycling or routine physiotherapy) and collect the primary outcome (physical function 3-days post-ICU discharge) and 90-day outcomes. We advised sites to prioritize data for the study's primary outcome. We sought feedback on pandemic barriers related to trial procedures. RESULTS: Our main Methods Centre mitigation strategies included identifying patients at risk for protocol deviations, communicating early and frequently with sites, developing standardized internal tools focused on high-risk points in the protocol for monitoring patient progress, data entry, and validation, and providing guidance to conduct some research activities remotely. For study sites, our strategies included determining how institutional pandemic research policies applied to CYCLE, communicating with the Methods Centre about capacity to continue any part of the research, and developing contingency plans to ensure the protocol was delivered as intended. From 15 active sites (12 Canada, 2 US, 1 Australia), 5 patients were still receiving the study intervention in ICUs, 6 required primary outcomes, and 17 required 90-day assessments. With these mitigation strategies, we attempted 100% of ICU interventions, 83% of primary outcomes, and 100% of 90-day assessments per our protocol. CONCLUSIONS: We retained all enrolled patients with minimal missing data using several time-sensitive strategies. Although CONSERVE recommends reporting only major modifications incurred by extenuating circumstances, we suggest that it also provides a helpful framework for reporting mitigation strategies with the goal of improving research transparency and trial management.

Lamotrigine-Induced Lupus With Aseptic Meningitis and Hemophagocytic Lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome characterized by disordered immune activation resulting in cytokine storm and inflammation. We present a 27-year-old woman who had a fever and diffuse rash after recently starting lamotrigine. She developed meningismus and polyarthralgia. Laboratory results revealed cytopenia, elevated serum aminotransferases, hypofibrinogenemia and elevated ferritin. Cerebrospinal fluid analysis suggested aseptic meningitis. Antinuclear antibody and rheumatoid factor serologies were positive, complement levels of C3 were decreased, and antihistone antibody was negative. A bone marrow biopsy demonstrated hemophagocytic macrophages and the diagnosis of HLH was made. The patient was empirically started on high-dose intravenous dexamethasone following which both her mental status and laboratory indices markedly improved. Lamotrigine has been shown to induce lupus-like syndrome, aseptic meningitis, and HLH, but not concomitantly. Our patient was recently started on lamotrigine, likely inducing her underlying undiagnosed lupus, in addition to, resulting in aseptic meningitis and a cytokine storm leading to HLH.

Exploring the effects of racial and socioeconomic factors on timeliness of lung cancer diagnosis and treatment in Baltimore Veterans.

OBJECTIVES: To characterize the effect of racial and socioeconomic factors on the timeliness of lung cancer diagnosis and treatment in a single-center Veterans Affair Medical Center (VAMC) pulmonary nodule clinic. METHODS: We conducted a single-center retrospective review of all patients seen at the Baltimore VAMC pulmonary nodule clinic between 2013 and 2019 to identify key demographic factors, measures of neighborhood socioeconomic disadvantage, cancer staging and histopathologic information, and time elapsed between diagnosis and treatment. We excluded patients with pulmonary nodules undergoing active surveillance, prior history of lung cancer, metastases of a different primary origin, insufficient followup, or who had received care outside the VHA system. RESULTS: Median times to diagnosis and treatment of lung cancer were 28 and 73 days. There were no statistically significant differences in overall timeliness of diagnosis and treatment when stratified by race or measures of neighborhood socioeconomic disadvantage. CONCLUSIONS: The authors found no differences in timeliness of lung cancer care by race and socioeconomic status within the system. Despite general adherence to national standards in timeliness of care, there continues to be a need for improvements in the operational workflows to reduce time to diagnosis and treatment for all Veterans.

The Effect of a Dedicated Lung Mass Clinic on Lung Nodule Follow Up.

Introduction: With the increased use of computed tomography (CT) imaging, lung nodules are found yearly requiring tracking and guideline directed follow up imaging. We describe the structure of a clinic dedicated to lung nodule tracking, patient education and the outcomes of lung nodule follow up. Methods: Patient electronic medical record charts were reviewed for lung nodules requiring tracking to determine if a follow up study was ordered, completed by the patient, and completed in an appropriate time frame. Patients were grouped based on referral to pulmonary clinic, lung mass clinic, or no subspecialty clinic. 700 CT reports were extracted from the electronic medical record of which 350 (50%) had lung nodules reported on CT, and 111 (15.9%) were lung nodules that additionally recommended discrete follow up in the radiologist report at the Veterans Health Administration hospital in Baltimore. Of these 111 patients, 95% were male and 5% were female. The mean age of the population was 66.3 ± 7.7 years. Results and Discussion: Patients seen in the lung mass clinic had a statistically significant higher rate of the follow up study being ordered by the provider. The lung mass clinic also had a higher percentage of patients who completed the study and completed the study within the recommended time frame, however, this was not statistically significant. Conclusion: A dedicated lung mass clinic should be considered as a method of improving lung nodule tracking with the added benefit of patient education and multidisciplinary care.

Feasibility of Tele-Training to Acquire Sublingual Microcirculatory Images.

Background: Recent advances in device technology and image analysis software used to assess the sublingual microcirculation have expanded clinicians' understanding of hemodynamics beyond assessments of blood pressure and end-organ function to provide unique insight into blood flow at the tissue level. Similarly, significant advances in virtual education and telemedicine have transpired recently, especially during the coronavirus disease (COVID-19) pandemic. However, the training of clinicians to acquire microcirculation images continues to rely on in-person instruction, which can be limited by available local expertise and resources, as well as geographic access to instructors. Objective: Our project aimed to test the feasibility of deploying an online curriculum in combination with tele-guidance versus an in-person guided approach to instruct novices to understand basic principle of microcirculatory function and to acquire sublingual microcirculatory images. Methods: After participating in brief didactics, 14 participants were divided into two groups to acquire microcirculatory images on a healthy volunteer. Each participant either 1) obtained images after an in-person demonstration or 2) obtained images with tele-guidance by using FaceTime technology. We recorded individual microcirculation quality scores, necessary time to acquire each image, percentage of correct theoretical questions on assessments, participant satisfaction with the curriculum, and participants' degree of confidence with image acquisition. Results: Participants' image quality scores (14.7 vs. 23.6, P = 0.3) and time to acquire images (191.2 vs. 199.4 s) did not significantly differ. In addition, participants' scores on theoretical knowledge assessments improved over the course of training (19.0% vs. 54.8%, P < 0.05). Conclusion: This feasibility study provides a novel framework for how to successfully deploy asynchronous education and telemedicine to direct novices to acquire sublingual microcirculatory images. Using technological advances to teach microcirculation may enhance wide-scale adoption of a promising clinical monitoring tool for critically ill patients.

MUC1 ectodomain is a flagellin-targeting decoy receptor and biomarker operative during Pseudomonas aeruginosa lung infection.

We previously reported that flagellin-expressing Pseudomonas aeruginosa (Pa) provokes NEU1 sialidase-mediated MUC1 ectodomain (MUC1-ED) desialylation and MUC1-ED shedding from murine lungs in vivo. Here, we asked whether Pa in the lungs of patients with ventilator-associated pneumonia might also increase MUC1-ED shedding. The levels of MUC1-ED and Pa-expressed flagellin were dramatically elevated in bronchoalveolar lavage fluid (BALF) harvested from Pa-infected patients, and each flagellin level, in turn, predicted MUC1-ED shedding in the same patient. Desialylated MUC1-ED was only detected in BALF of Pa-infected patients. Clinical Pa strains increased MUC1-ED shedding from cultured human alveolar epithelia, and FlaA and FlaB flagellin-expressing strains provoked comparable levels of MUC1-ED shedding. A flagellin-deficient isogenic mutant generated dramatically reduced MUC1-ED shedding compared with the flagellin-expressing wild-type strain, and purified FlaA and FlaB recapitulated the effect of intact bacteria. Pa:MUC1-ED complexes were detected in the supernatants of alveolar epithelia exposed to wild-type Pa, but not to the flagellin-deficient Pa strain. Finally, human recombinant MUC1-ED dose-dependently disrupted multiple flagellin-driven processes, including Pa motility, Pa biofilm formation, and Pa adhesion to human alveolar epithelia, while enhancing human neutrophil-mediated Pa phagocytosis. Therefore, shed desialylated MUC1-ED functions as a novel flagellin-targeting, Pa-responsive decoy receptor that participates in the host response to Pa at the airway epithelial surface.

Antipsychotic Medication-Induced Hyperthermia Leading to Cerebrovascular Accident: A Case Report.

Antipsychotic medications are used in the management of schizophrenia. Antipsychotic medications treat both positive and negative symptoms via the dopamine D2 receptor and serotonin 5-HT2A blockade pathway. Side effects include hyperprolactinemia, prolonged QTc, and neuroleptic malignant syndrome. However, antipsychotic medication-induced hyperthermia potentiating a cerebrovascular accident (CVA) is a rare side effect that is less well known. A 47-year-old male presented to the emergency department (ED) via emergency medical services for altered mental status. He was given naloxone without improvement in mental status. His glucose was 110 mg/dL. Upon presentation to the ED, he was hyperthermic (106.7 degrees Fahrenheit) and tachycardic (heart rate of 160's beats/minute). Home medications included risperidone and fluphenazine. After the resolution of his hyperthermia, he had a right-sided facial droop concerning a cerebrovascular accident. Magnetic resonance imaging (MRI) of the brain confirmed an early/acute subacute right cerebellar infarction. The patient received optimal treatment; his mental status returned to baseline, and he was discharged home without antipsychotic medications. Patients who are prescribed antipsychotics should be aware of the potentially fatal adverse events that can occur from these medications. Thermoregulation may be impaired in these patients, resulting in significant hyperthermia, in which case antipsychotic medications should be discontinued.

COVID-19 Presenting as Recurrent Pericardial Effusion.

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) emerged from Wuhan, China, in 2019, causing coronavirus disease 19 (COVID-19) and creating a global pandemic affecting millions of people worldwide. Though COVID-19 primarily affects the pulmonary structures, deleterious effects can also occur in the cardiac system. We present a case of a patient with recurrent pericardial effusions secondary to COVID-19 infection, an unusual cardiovascular manifestation of this disease. A 47-year-old man presented with altered mental status and tested positive for COVID-19. He left against medical advice and later presented two weeks later with pleuritic chest pain associated with shortness of breath. His symptoms were attributed to a moderate- to large-sized pericardial effusion, without evidence of tamponade, as confirmed by echocardiography. The fluid was removed by pericardiocentesis; analysis was negative for malignant cells, inflammatory markers, or microbiologic studies. Reaccumulation of the fluid necessitated placement of a pericardial window, resulting in the resolution of his symptoms. There are limited case reports demonstrating the association of pericardial effusion with COVID-19 infection. The effusion is likely secondary to the inflammatory response leading to capillary leakage, resulting in pericardial fluid traversing the serous pericardium. In addition to other demonstrated cardiovascular effects, COVID-19 appears to be associated with recurrent pericardial effusion. Due to the rise in COVID-19 cases, it is essential to consider pericardial effusion as a rare but potential complication of this virus. The pericardial effusion can be the primary clinical manifestation, recurrent in nature, and potentially result in tamponade physiology.

Assessing calorie and protein recommendations for survivors of critical illness weaning from prolonged mechanical ventilation - can we find a proper balance?

BACKGROUND & AIMS: Survivors of critical illness requiring prolonged mechanical ventilation (PMV) are predisposed to malnutrition, muscle wasting, and weakness. There is a lack of data regarding nutrition adequacy among these patients, and although nitrogen balance has been studied as a marker of adequate protein intake in healthy individuals and acutely critically ill patients, it has not been well studied in critically ill patients with PMV. The purpose of this study was to determine if patients requiring PMV admitted to a long-term acute care hospital (LTACH) achieved registered dietitian (RD) recommended goals for energy and protein intake and if the recommendations were adequate to avoid negative nitrogen balance. METHODS: Using a retrospective, cohort study design, patients requiring PMV who had orders for 24-h urine collections for urea nitrogen (24hrUUN) were included. Energy and protein intake was calculated from chart documentation of dietary intake for the 24-h period during which patients underwent a 24hrUUN. Nitrogen intake was estimated from protein intake. Dietary intake was compared to RD-recommendations to determine the percentage of RD-recommendations achieved. Nitrogen balance was calculated as nitrogen intake minus nitrogen loss, with negative balance categorized as less than -1. RESULTS: Subjects (n = 16) were 38% male and 75% African American (mean age 61.5 ± 3.2 years; mean BMI 27.5 ± 2.5 kg/m2). Duration of LTACH hospitalization was 26.5 (6-221) days. Mean energy and protein intake was 21.7 ± 2.9 kcal/kg/d and 1.1 ± 0.1 g/kg/d, respectively, which corresponded to 86% of both RD energy and protein recommendations. Ten patients achieved a positive nitrogen balance (mean 0.9 ± 1.1 g). In addition, there was a positive linear relationship between protein intake and nitrogen balance (r = 0.59, p = 0.016). CONCLUSION: Survivors of critical illness requiring PMV achieved a high percentage of RD-recommended protein and calories, and prevented a negative nitrogen balance in a majority of patients. Increasing protein intake can prevent a negative nitrogen balance. Future studies should evaluate whether these patients are able to maintain a steady state of nitrogen intake and excretion over time and how this affects time to and/or success of weaning.

Enhancing motor learning in people with stroke via memory reactivation during sleep.

PURPOSE: Investigate the use of repetitive delivery of task-related auditory cues, known as targeted memory reactivation (TMR), throughout a 1-hour daytime nap to enhance motor learning in individuals with chronic stroke. RESEARCH METHOD: Participants with a history of stroke at least 6 months prior were recruited to perform a novel overhand throwing task to randomly appearing target locations using the nonparetic upper extremity immediately before and after a 1-hour daytime nap. Half of the participants received TMR during the nap. RESULTS: Participants who received TMR demonstrated a greater overall reduction in absolute and variable spatial errors relative to the NoTMR control group. Both groups demonstrated similar generalization of skill to 2 untrained variants of the trained task, but not to a novel untrained task. CONCLUSIONS: This study suggests that TMR may enhance motor learning after stroke. Future studies should investigate whether TMR can lead to improvements of the paretic upper extremity during clinically based rehabilitation interventions.
