Early physical therapy for a patient affected by coronavirus disease 2019 (COVID-19) on awake veno-venous extracorporeal membrane oxygenation: a case report.

Since December 8, 2019, an acute respiratory illness has spread rapidly in China, causing 3,097 people to die as of March 7, and it has become a global crisis. The common symptoms are fever, fatigue, dry cough, myalgia, and dyspnea. This case report presents a 36-year-old male who was diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected pneumonia on February 2, 2020. This patient received veno-venous extracorporeal membrane oxygenation (V-V ECMO) last for 10 days as salvage treatment as his condition became critical in the acute setting. As soon as his status became stable, he began to receive an early rehabilitation program performed by our rehabilitation team. After 43 days of treatment under the efforts of our teamwork, the patient was able to walk 800 meters, and then was discharged the next day. To our knowledge, this is the first report of early physical therapy for a patient with coronavirus disease 2019 (COVID-19) who was receiving extracorporeal membrane oxygenation (ECMO) whilst awake. This case indicates that early physical rehabilitation is safe and feasible and resulted in an expedited recovery using ECMO whilst awake. The goals for physiotherapy management include avoiding atelectasis, airway clearance, weaning and increasing the functional level. This report may contribute to the current literature on early physical therapy rehabilitation programs for awake ECMO patients.

Early rehabilitation after lung transplantation with extracorporeal membrane oxygenation (ECMO) of COVID-19 patient: a case report.

Even when severe acute respiratory syndrome coronavirus 2-related coronavirus disease 2019 (COVID-19) is treated with first-line drugs, it progresses and leads to irreversible loss of lung function in some critically ill patients, and lung transplantation is an effective treatment for end-stage chronic pulmonary disease. This case report mainly describes the rehabilitation of a 66-year-old female patient with severe COVID-19 after bilateral lung transplantation. The old patient had a body mass index of 31.2 kg/m2. She underwent bilateral lung transplantation due to severe and irreversible injury of both lungs. Long-term mechanical ventilation and extracorporeal membrane oxygenation (ECMO) treatment and preoperative and postoperative high-dose corticosteroid therapy and due to the size of the donor lung does not match the size of the recipient's diseased lung, and the right middle lobe of the graft is removed before transplantation. Weaning from the ventilator failed due to weak neuromuscular drive, and muscle strength. A full, personalized pulmonary rehabilitation program was initiated with the help of the physical therapists, the respiratory therapy, the doctors, the nurses and psychotherapist team based on the functional levels. The rehabilitation intervention was conducted on postoperative day 4, This included posture management, airway clearance techniques, respiratory training, muscle strength training, transfer training, daily therapeutic bronchoscopy and psychological support. The ECMO was removed successfully on the fifth day. the patient's physical function, muscle strength and the quality of life has been improved. The good prognosis after rehabilitation indicates that early rehabilitation intervention is effective and feasible and safety for patients after lung transplantation.

Low Hemoglobin Levels at Admission Are Independently Associated with Cognitive Impairment after Ischemic Stroke: a Multicenter, Population-Based Study.

Data on the association between hemoglobin (Hb) levels and poststroke cognitive function are limited. We investigated the relationship between Hb concentrations at admission and poststroke cognitive function using a multicenter database. In total, 1081 patients were recruited from seven Chinese medical centers within 6 months after experiencing ischemic stroke. Cognitive status was evaluated with a series of brief neuropsychological tests. A subgroup of 439 patients from a single center was followed up for 4-6 years and was eventually reassessed with a cognitive test. The association between Hb and cognitive impairment was analyzed by multivariable Tobit regression and logistic regression. The mean age of the 920 eligible participants at study entry was 42.5 years; 311 (34%) were women, and all participants were Chinese nationals who lived locally. After adjustment for multiple covariables, Hb levels at admission remained positively associated with poststroke Mini-Mental State Examination (MMSE) scores, with a 0.37-point increase in the MMSE score for every 1-standard-deviation increase in the Hb level. Moreover, an optimal Hb level above 15.0 g/dl was proposed for preventing or alleviating the development of poststroke cognitive impairment in men. After 4-6 years of rehabilitation, the baseline Hb still correlated with MMSE scores. A significant interaction was found between baseline Hb and change in MMSE scores over time, with higher baseline Hb levels predicting faster recovery of global cognitive performance (ß, 0.21; 95% confidence interval, 0.03-0.39).These findings warrant further study of anemia as a risk factor for poststroke cognitive impairment.

Efficiency of Repetitive Transcranial Direct Current Stimulation of the Dorsolateral Prefrontal Cortex in Disorders of Consciousness: A Randomized Sham-Controlled Study.

Conventional transcranial direct current stimulation (tDCS) targeting the left dorsolateral prefrontal cortex (DLPFC) could improve arousal in disorders of consciousness (DOC). However, the comparative effectiveness of anodal stimulation of the left DLPFC and the electrophysiological effect of tDCS are yet to be determined. In this randomized sham-controlled design, patients were separated into three groups (left/right anodal tDCS, sham). Data on the clinical assessments and EEG were collected at baseline and after 2 weeks of tDCS. The outcome at 3-month follow-up was evaluated using the Glasgow Outcome Scale-Extended. Results showed that sessions of the left tDCS facilitated the excitability of the prefrontal cortex, whereas only one patient had a positive outcome. Targeting the right DLPFC was less effective, merely leading to activation of the stimulation site, with no effect on the state of arousal. Moreover, sham stimulation had minimal or no effect on any of the outcomes. These results provide evidence for a hemispheric asymmetry of tDCS effects in patients with DOC. Left anodal tDCS might be more effective for modulating cortical excitability compared to tDCS on the right DLPFC. However, future studies with large sample sizes are needed to confirm these findings. This trial is registered with NCT03809936.

Functional Connectivity of Anterior Insula Predicts Recovery of Patients With Disorders of Consciousness.

Background: We hypothesize that the anterior insula is important for maintenance of awareness. Here, we explored the functional connectivity alterations of the anterior insula with changes in the consciousness level or over time in patients with disorders of consciousness (DOC) and determined potential correlation with clinical outcomes. Methods: We examined 20 participants (9 patients with DOC and 11 healthy controls). Each patient underwent resting-state functional magnetic resonance imaging (rs-fMRI) and a standardized Coma Recovery Scale-Revised (CRS-R) assessment on the same day. We categorized the patients according to the prognosis: those who emerged from a minimally conscious state (recovery group, n = 4) and those who remained in the unconscious state (unrecovery group, n = 5). Two rs-fMRI scans were obtained from all patients, and the second scan of patients in the recovery group was obtained after they regained consciousness. We performed seed-based fMRI analysis and selected the left ventral agranular insula (vAI) and dorsal agranular insula (dAI) as the regions of interest. Correlations with CRS-R were determined with the Spearman's correlation coefficient. Results: Compared with healthy controls, the functional connectivity between dAI and gyrus rectus of patients who recovered was significantly increased (p < 0.001, cluster-wise family-wise error rate [FWER] < 0.05). The second rs-fMRI scan of patients who remained with DOC showed a significant decreased functional connectivity between the dAI to contralateral insula, pallidum, bilateral inferior parietal lobule (IPL), precentral gyrus, and middle cingulate cortex (p < 0.001, cluster-wise FWER < 0.05) as well as the functional connectivity between vAI to caudate and cingulum contrast to controls (p < 0.001, cluster-wise FWER < 0.05). Finally, the functional connectivity strength of dAI-temporal pole (Spearman r = 0.491, p < 0.05) and dAI-IPL (Spearman r = 0.579, p < 0.05) were positively correlated with CRS-R scores in all DOC patients. The connectivity of dAI-IPL was also positively correlated with clinical scores in the recovery group (Spearman r = 0.807, p < 0.05). Conclusions: Our findings indicate that the recovery of consciousness is associated with an increased connectivity of the dAI to IPL and temporal pole. This possibly highlights the role of the insula in human consciousness. Moreover, longitudinal variations in dAI-IPL and dAI-temporal pole connectivity may be potential hallmarks in the outcome prediction of DOC patients.
