RESUMEN
In order to analyze the clinical characteristics of death cases in the oral emergency department of the stomatological hospital, and to improve the first aid technique before and in hospitals, we collected the clinical data of death cases in the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2010 to January 2023 for retrospective analysis. General cha-racteristics, such as the patients' gender, age, chief complaint, maxillofacial diseases, systemic underlying diseases, rescue situation, cause of death and seasonal distribution of death were summarized. The results showed that a total of 8 death cases (5 males and 3 females) occurred during the 13-year period, ranging in age from 40 to 86 years, with a median age of 66 years. Among the 8 patients, 5 reported bleeding from oral cancer, 1 reported chest tightness and dyspnea after oral cancer surgery, 1 reported loss of consciousness after maxillofacial trauma, and 1 reported oral erosion and aphagia. All the 8 patients had one or more underlying diseases, such as hypertension, coronary heart disease, diabetes, renal failure, and cerebral infarction, etc. and 2 of them showed dyscrasia. Among them, the cause of death in 5 cases was respiratory and circulatory failure caused by oral cancer rupture and hemorrhage or poor surgical wound healing and hemorrhage; 1 case was uremia and hyperkalemia leading to circulatory failure; 1 case was asphyxia caused by swelling of oral floor tissue after maxillofacial trauma; and the other case was acute myocardial infarction caused circulatory failure after oral cancer surgery. According to the vital state at the time of treatment, 6 patients had loss of consciousness, respiratory and cardiac arrest before hospital, and 2 patients suffered from loss of consciousness, respiratory and cardiac arrest during treatment. All the patients received cardiopulmonary resuscitation and some advanced life support measures, and the average rescue time was 46 min. Due to the low incidence of death in the oral emergency department, medical personel have little experience in first aid. First aid training and drills and assessment should be organized regularly. First aid facilities should be always available and regularly maintained by special personnel, such as electrocardiogram (ECG) monitor, defibrillator, simple breathing apparatus, oxygen supply system, negative pressure suction system, endotracheal intubation and tracheotomy equipment. The death cases mainly occurred in the elderly patients with oral cancer bleeding and systemic underlying diseases. Education of emergency awareness for the elderly patients with oral cancer after surgery should be enhanced. Medical staff should strengthen first aid awareness and skills.

BACKGROUND: Stroke is one of the neurological manifestations of COVID-19, leading to a significant risk of morbidity and mortality. Clinical manifestations and laboratory parameters were investigated to determine mortality predictors in this case. METHOD: The case control study was conducted at Dr. Sardjito General Hospital,Yogyakarta, Indonesia, with data collected between July 2020 and August 2021. All recorded clinical and laboratory data from acute stroke patients with confirmed COVID-19 were collected. Baseline characteristics, bivariate, and multivariate analyses were assessed to determine significant predictors for mortality. RESULT: This study involved 72 subjects with COVID-19 and stroke. The majority experienced ischemic stroke, with hypertension as the most prevalent comorbidity. Notably, 45.8% of subjects (p < 0.05) loss of consciousness and 72.2% of exhibited motor deficits (p < 0.05). Severe degree of COVID-19 was observed in 52.8% of patients, with respiratory distress and death rates of 56.9% and 58.3%. Comparison of surviving and deceased groups highlighted significant differences in various clinical and laboratory characteristics differences. Hazard ratio (HR) analysis identified loss of consciousness (HR = 2.68; p = 0.01), motor deficit (HR = 2.34; p = 0.03), respiratory distress (HR = 81.51; p < 0.001), and monocyte count (HR:1.002; p = 0.04) as significant predictors of mortality. CONCLUSION: Mortality in COVID-19 patients with stroke was significantly associated with loss of consciousness, motor deficit, respiratory distress, and raised monocyte count. The risk of mortality is heightened when multiple factors coexist.

PURPOSE: The primary aim was to compare the prevalence of acute and delayed intracranial haemorrhage (ICH) following mild traumatic brain injury (mTBI) in patients on antithrombotic medication referred to a clinic for oral and plastic maxillofacial surgery. The secondary aim was to evaluate the need for short-term hospitalisation based on initial radiological and clinical findings. METHODS: This was an observational retrospective single-centre study of all patients on antithrombotic medication who were admitted to our department of oral and plastic maxillofacial surgery with mTBI over a 5 year period. Demographic and anamnesis data, injury characteristics, antithrombotic medication, radiological findings, treatment, and outcome were analysed. Patients were divided into the following four groups based on their antithrombotic medication: (1) single antiplatelet users, (2) vitamin K antagonist users, (3) direct oral anticoagulant users, and (4) double antithrombotic users. All patients underwent an emergency cranial CT (CT0) at admission. Based on clinical and radiological evaluation, different treatment protocols were applied. Patients with positive CT0 findings and patients with secondary neurological deterioration received a control CT (CT1) before discharge. Acute and delayed ICH and patient's outcome during hospitalisation were evaluated using descriptive statistical analysis. RESULTS: A total of 696 patients (mean age, 71.6 years) on antithrombotic medication who presented at our department with mTBI were included in the analysis. Most injuries were caused by a ground-level fall (76.9%). Thirty-six patients (5.1%) developed an acute traumatic ICH, and 47 intracerebral lesions were detected by radiology-most of these in patients taking acetylsalicylic acid. No association was detected between ICH and antithrombotic medication (p = 0.4353). In total, 258 (37.1%) patients were admitted for 48 h in-hospital observation. The prevalence of delayed ICH was 0.1%, and the mortality rate was 0.1%. Multivariable analysis identified a Glasgow Coma Scale (GCS) of < 15, loss of consciousness, amnesia, headache, dizziness, and nausea as clinical characteristics significantly associated with an increased risk of acute ICH, whereas age, sex, and trauma mechanism were not associated with ICH prevalence. Of the 39 patients who underwent a control CT1, most had a decreasing or at least constant intracranial lesion; in three patients, intracranial bleeding increased but was not clinically relevant. CONCLUSION: According to our experience, antithrombotic therapy does not increase the rate of ICH after mTBI. A GCS of < 15, loss of consciousness, amnesia, headache, dizziness, and nausea are indicators of higher ICH risk. A second CT scan is more effective in patients with secondary neurological deterioration. Initial CT findings were not clinically relevant and should not indicate in-hospital observation.

BACKGROUND AND OBJECTIVES: Traumatic brain injuries (TBIs) are associated with increased risk of dementia, but whether lifetime TBI influences cognitive trajectories in later life is less clear. Cognitive interventions after TBI may improve cognitive trajectories and delay dementia. Because twins share many genes and environmental factors, we capitalize on the twin study design to examine the association between lifetime TBI and cognitive decline. METHODS: Participants were members of the National Academy of Sciences-National Research Council's Twin Registry of male veterans of World War II with self or proxy-reported history of TBI and with up to 4 observations over 12 years of the modified Telephone Interview for Cognitive Status (TICS-m). We used linear random-effects mixed models to analyze the association between TBI and TICS-m in the full sample and among co-twins discordant for TBI. Additional TBI predictor variables included number of TBIs, severity (loss of consciousness [LOC]), and age of first TBI (age <25 vs 25+ years [older age TBI]). Models were adjusted for age (centered at 70 years), age-squared, education, wave, twin pair, lifestyle behaviors, and medical conditions. RESULTS: Of 8,662 participants, 25% reported TBI. History of any TBI (ß = -0.56, 95% CI -0.73 to -0.39), TBI with LOC (ß = -0.51, 95% CI -0.71 to -0.31), and older age TBI (ß = -0.66, 95% CI -0.90 to -0.42) were associated with lower TICS-m scores at 70 years. TBI with LOC (ß = -0.03, 95% CI -0.05 to -0.001), more than one TBI (ß = -0.05, 95% CI -0.09 to -0.002,), and older age TBI (ß = -0.06, 95% CI -0.09 to -0.03) were associated with faster cognitive decline. Among monozygotic pairs discordant for TBI (589 pairs), history of any TBI (ß = -0.55, 95% CI -0.91 to -0.19) and older age TBI (ß = -0.74, 95% CI -1.22 to -0.26) were associated with lower TICS-m scores at 70 years. Those with more than one TBI (ß = -0.13, 95% CI -0.23 to -0.03) and older age TBI (ß = -0.07, 95% CI -0.13 to -0.002) showed greater cognitive decline compared with their co-twin without TBI. DISCUSSION: These findings support an association of the effect of TBI on cognitive score and the rapidity of cognitive decline in later life. The results in monozygotic pairs, who share all genes and many exposures, particularly in early life, provide additional evidence of a causal relationship between TBI and poorer late-life cognitive outcomes.

OBJECTIVE: Although pneumonia is the leading cause of death among patients with dementia, the specific underlying causes remain unclear. In particular, the potential connection between pneumonia risk and dementia-related daily living difficulties, such as oral hygiene practice and mobility impairment, and the use of physical restraint as a management practice, has not been extensively studied. METHODS: In our retrospective study, we included 454 admissions corresponding to 336 individual patients with dementia who were admitted to a neuropsychiatric unit due to behavioral and psychological symptoms. The admissions were divided into two groups: those who developed pneumonia while hospitalized (n=62) and those who did not (n=392). We investigated differences between the two groups in terms of dementia etiology, dementia severity, physical conditions, medical complications, medication, dementia-related difficulties in daily living, and physical restraint. To control potential confounding variables, we used mixed effects logistic regression analysis to identify risk factors for pneumonia in this cohort. RESULTS: Our study found that the development of pneumonia in patients with dementia was associated with poor oral hygiene, dysphagia, and loss of consciousness. Physical restraint and mobility impairment showed a weaker, nonsignificant association with the development of pneumonia. CONCLUSIONS: Our findings suggest that pneumonia in this population may be caused by two primary factors: increased pathogenic microorganisms in the oral cavity due to poor hygiene, and an inability to clear aspirated contents due to dysphagia and loss of consciousness. Further investigation is needed to clarify the relationship between physical restraint, mobility impairment, and pneumonia in this population.

Despite the reduction of death from pneumonia over recent years, pneumonia has still been the leading infectious cause of death in under-five children for the last several decades. Unconsciousness is a critical condition in any child resulting from any illness. Once it occurs during a pneumonia episode, the outcome is perceived to be fatal. However, data on children under five with pneumonia having unconsciousness are scarce. We've retrospectively analyzed the data of under-five children admitted at the in-patient ward of Dhaka Hospital of icddr,b during 1 January 2014 and 31 December 2017 with World Health Organization classified pneumonia or severe pneumonia. Children presented with or without unconsciousness were considered as cases and controls respectively. Among a total of 3,876 children fulfilling the inclusion criteria, 325 and 3,551 were the cases and the controls respectively. A multivariable logistic regression analysis revealed older children (8 months vs. 7.9 months) (adjusted odds ratio, aOR 1.02, 95% CI: 1.004-1.04, p = 0.015), hypoxemia (aOR 3.22, 95% CI: 2.39-4.34, p<0.001), severe sepsis (aOR 4.46, 95% CI: 3.28-6.06, p<0.001), convulsion (aOR 8.90, 95% CI: 6.72-11.79, p<0.001), and dehydration (aOR 2.08, 95% CI: 1.56-2.76, p<0.001) were found to be independently associated with the cases. The cases more often had a fatal outcome than the controls (23% vs. 3%, OR 9.56, 95% CI: 6.95-13.19, p<0.001). If the simple predicting factors of unconsciousness in children under five hospitalized for pneumonia with different severity can be initially identified and adequately treated with prompt response, pneumonia-related deaths can be reduced more effectively, especially in resource-limited settings.

BACKGROUND: Prior studies into the association of head trauma with neuropathology have been limited by incomplete lifetime neurotrauma exposure characterization. OBJECTIVE: To investigate the neuropathological sequelae of traumatic brain injury (TBI) in an autopsy sample using three sources of TBI ascertainment, weighting findings to reflect associations in the larger, community-based cohort. METHODS: Self-reported head trauma with loss of consciousness (LOC) exposure was collected in biennial clinic visits from 780 older adults from the Adult Changes in Thought study who later died and donated their brain for research. Self-report data were supplemented with medical record abstraction, and, for 244 people, structured interviews on lifetime head trauma. Neuropathology outcomes included Braak stage, CERAD neuritic plaque density, Lewy body distribution, vascular pathology, hippocampal sclerosis, and cerebral/cortical atrophy. Exposures were TBI with or without LOC. Modified Poisson regressions adjusting for age, sex, education, and APOE É4 genotype were weighted back to the full cohort of 5,546 participants. RESULTS: TBI with LOC was associated with the presence of cerebral cortical atrophy (Relative Risk 1.22, 95% CI 1.02, 1.42). None of the other outcomes was associated with TBI with or without LOC. CONCLUSION: TBI with LOC was associated with increased risk of cerebral cortical atrophy. Despite our enhanced TBI ascertainment, we found no association with the Alzheimer's disease-related neuropathologic outcomes among people who survived to at least age 65 without dementia. This suggests the pathophysiological processes underlying post-traumatic neurodegeneration are distinct from the hallmark pathologies of Alzheimer's disease.

BACKGROUND: Helicobacter pylori bacteremia is rare and difficult to make a definite diagnosis. CASE PRESENTATION: This is a 40-year-old woman represented as fever and unconsciousness accompanied by tics. She was diagnosed as Helicobacter pylori bacteremia and received emergency endotracheal intubation and antibiotics. Her symptoms resolved and she was discharged from ICU at the sixth day. CONCLUSIONS: Helicobacter pylori bacteremia is rare and hard to identify. Varied clinical manifestations leading to more difficult to make a definite diagnosis.

Acute focal bacterial nephritis (AFBN) is a kidney disease characterized by a localized bacterial infection that manifests as an inflammatory mass. Most children with AFBN have nonspecific symptoms including fever, vomiting, and abdominal discomfort, and some develop neurological symptoms such as meningeal irritation, unconsciousness, and seizures as their condition worsens. This was 2 cases of AFBN with central nervous system manifestations in children, and we analyzed its possible mechanisms of the clinical and radiographic features. We experience 2 very unusual cases of AFBN which were linked to central nervous system abnormalities. A 6-year-old boy with AFBN and clinically moderate ncephalitis/encephalopathy with a reversible splenial lesion (MERS) presented with neurological symptoms, including unconsciousness and convulsions. The second case involved an 8-year-old child with AFBN-associated acute encephalopathy who exhibited neurological symptoms, including unconsciousness. According to previous research, AFBN is linked to central nervous system impairment. As a result, when a clinician meets a patient with an inexplicable fever caused by a neurological condition, he should pay attention to this diagnosis of AFBN and follow it in the abdominal graph.

BACKGROUND: The long-term effects of traumatic brain injury (TBI) with loss of consciousness (LOC) on magnetic resonance imaging (MRI) markers of brain health and on dementia risk are still debated. OBJECTIVE: To investigate the associations of history of TBI with LOC with incident dementia and neuroimaging markers of brain structure and small vessel disease lesions. METHODS: The analytical sample consisted in 4,144 participants aged 65 and older who were dementia-free at baseline from the Three City -Dijon study. History of TBI with LOC was self-reported at baseline. Clinical Dementia was assessed every two to three years, up to 12 years of follow-up. A subsample of 1,675 participants <80 years old underwent a brain MRI at baseline. We investigated the associations between history of TBI with LOC and 1) incident all cause and Alzheimer's disease (AD) dementia using illness-death models, and 2) neuroimaging markers at baseline. RESULTS: At baseline, 8.3% of the participants reported a history of TBI with LOC. In fully-adjusted models, participants with a history of TBI with LOC had no statistically significant differences in dementia risk (HRâ=â0.90, 95% CIâ=â0.60-1.36) or AD risk (HRâ=â1.03, 95% CIâ=â0.69-1.52), compared to participants without TBI history. History of TBI with LOC was associated with lower white matter volume (ß=â-4.58, pâ=â0.048), but not with other brain volumes, white matter hyperintensities volume, nor covert brain infarct. CONCLUSION: This study did not find evidence of an association between history of TBI with LOC and dementia or AD dementia risks over 12-year follow-up, brain atrophy, or markers of small vessel disease.

Hemophagocytic lymphohistiocytosis (HLH) involves pathological histiocytes and phagocytosis of normal blood cells through activation of inflammatory cytokines. We report a case of Epstein-Barr virus-HLH in a 75-year-old woman who presented with fever, thrombocytopenia, and loss of consciousness. Epstein-Barr virus-HLH was diagnosed after we identified massive hemophagocytosis in bone marrow and Epstein-Barr virus DNA in cerebrospinal fluid. The HLH-2004 protocol was applied, and lactate dehydrogenase levels-which reflect HLH disease status-decreased. However, persistent loss of consciousness and multiple organ failure led to the patient's death on day 18. Most cases of primary and secondary HLH involve pediatric patients; adult cases are rare. Few cases of central nervous system involvement in older adults have been reported. Therefore, accumulation of more data will help in developing better treatment strategies.

OBJECTIVE: Report the incidence of and treatment patterns for facial nerve palsy after skull base fracture. STUDY DESIGN: Retrospective cohort study. SETTING: IBM MarketScan Commercial Database (2006-2019). PATIENTS: Human subjects with skull base fracture, per International Classification of Diseases-9th and 10th Revisions-Clinical Modification diagnosis codes. MAIN OUTCOME MEASURES: The primary outcomes were the incidence and median time to facial nerve palsy diagnosis within 30 days of skull base fracture. Secondary outcomes were treatments (corticosteroids, antivirals, facial nerve decompression, botulinum toxin, and facial reanimation), demographics, and rates of hearing loss, vertigo, tympanic membrane rupture, cerebrospinal fluid leak, comorbidities, and loss of consciousness. RESULTS: The 30-day incidence of facial nerve palsy after skull base trauma was 1.0% (738 of 72,273 patients). The median (95% confidence interval [CI]) time to diagnosis was 6 (6-7) days, and only 22.9% were diagnosed within 1 day. There were significantly higher rates (risk difference, 95% CI) of hearing loss (26%, 22-29%), tympanic membrane rupture (6.3%, 4.5-8.1%), cerebrospinal fluid leak (6.4%, 4.5-8.3%), comorbidity (14%, 10.4-17.6%), and loss of consciousness (24.3%, 20.7-27.9%). Loss of consciousness was associated with longer median (95% CI) time to facial nerve palsy diagnosis: 10 (9-10) days. Corticosteroids were the most common treatment but only reported for less than one-third of patients. Only eight patients underwent facial nerve decompression. CONCLUSIONS: Facial nerve palsy after skull base fracture is associated with higher comorbidity, and the diagnosis is often delayed. Few patients were treated with surgery, and there are inconsistencies in the types and timing of treatments.

BACKGROUND: Blast lung overpressure has received interest as a cause of chronic respiratory disease in Service members who deployed in support of U.S. military operations in Southwest Asia and Afghanistan since 2001. We studied whether veterans who experienced blast exposure report more chronic respiratory symptoms and diagnoses compared to deployed veterans who did not. METHODS: 9,000 veterans included in the Department of Veterans Affairs Toxic Embedded Fragment Registry were invited to complete a survey assessing chronic respiratory symptoms, diagnoses, and exposures. Blast exposure was assessed using the Brief Traumatic Brain Injury Screen and by presence of other symptoms such as blast-induced loss of consciousness. RESULTS: Participants (n = 2147) were predominantly <40 years old, served in the Army, and injured on average 12.8 years previously. 91% reported blast exposure. Blast-exposed veterans were significantly more likely to report cough (OR 1.8), wheeze (OR 2.4), and dyspnea (OR 1.8), even after adjustment for covariates including smoking and occupational exposures to dust, fume, and gas. Veterans reporting higher severity of blast impact, such as traumatic brain injury or loss of consciousness, were more likely to report cough, wheeze, or dyspnea. Veterans with higher severity of blast impact by multiple measures were also more likely to report having COPD. Those reporting a physician-diagnosis of traumatic brain injury were significantly more likely to report having both asthma (OR 1.5) and COPD (OR 1.5). CONCLUSIONS: Blast exposure is associated with respiratory symptoms and COPD. Respiratory system evaluation may warrant inclusion as a standard part of barotrauma health assessment.

INTRODUCTION: Diabetic ketoacidosis (DKA) is a complication of diabetes presenting with high anion gap metabolic acidosis. Methanol poisoning, on the other hand, is a toxicology emergency which presents with the same feature. We present a case of methanol poisoning who presented with DKA. CASE PRESENTATION: A 28-year-old male was referred to us with blurred vision and loss of consciousness three days after ingestion of 1.5 L of an unknown mixture of bootleg alcoholic beverage. He had history of insulin-dependent diabetes and had neglected his insulin shots on the day prior to hospital admission due to progressive loss of consciousness. Vital signs were normal and venous blood gas analysis showed severe metabolic acidosis and a methanol level of 10.2 mg/dL. After eight hours of hemodialysis, he remained unresponsive. Diabetic ketoacidosis was suspected due to positive urine ketone and blood sugar of 411 mg/dL. Insulin infusion was initiated which was followed by full awakening and extubation. He was discharged completely symptom-free after 4 weeks. CONCLUSIONS: Diabetic ketoacidosis and methanol poisoning can happen simultaneously in a diabetic patient. Given the analogous high anion gap metabolic acidosis, physicians should pay particular attention to examination of the diabetic patients. Meticulous evaluation for both conditions is highly recommended.

A 43-year-old male Bell 214C helicopter pilot presented to the emergency ward with flu-like syndrome. His nasopharyngeal severe acute respiratory syndrome coronavirus 2 real-time polymerase chain reaction test was positive, and a chest computed tomographic scan confirmed coronavirus disease 2019 pneumonia. He was admitted, received treatment, was discharged, and returned to flying. During the mission debrief, copilots who had flown with him reported that he experienced episodes of in-flight dizziness and blacked out. They occurred briefly during the cruise and hovering flight, perhaps for a few seconds of disorientation and unconsciousness. Rapid identification of the copilot and control of the helicopter prevented any incident or accident. Afterward, he explained the sudden onset and unexpected brief periods of loss of consciousness after a headache. The flight safety office referred him to the aviation medical center for further investigations. The cardiovascular, neurologic, laboratory, and toxicologic assessments were inconclusive with the approach to sudden-onset transient loss of consciousness. The only abnormal finding was hippocampus lesions on brain magnetic resonance imaging (MRI). Because of the possible diagnosis of transient global amnesia, the aviation medical examiner suspended him from flight duties until complete recovery and the absence of any probable complications.

Currently, in young children with minor traumatic head injuries (MTHI) classified as intermediate risk (IR), PECARN recommends clinical observation over computer tomography (CT) scan depending on provider comfort, although both options being possible. In this study, we describe clinicians' choice and which factors were associated with this decision. This was a planned sub-study of a prospective multicenter observational study that enrolled 1006 children younger than 18 years with MTHI who presented to six emergency departments in The Netherlands. Of those, 280 children classified as IR group fulfilling one or more minor criteria, leaving the clinician with the choice between clinical observation and a CT scan. In our cohort, 228/280 (81%) children were admitted for clinical observation, 15/280 (5.4%) received a CT scan, 6/280 (2.1%) received a CT scan and were admitted for observation, and 31/280 (11%) children were discharged from the emergency department without any intervention. Three objective factors were associated with a CT scan, namely age above 2 years, the presence of any loss of consciousness (LOC), and presentation on weekend days. CONCLUSION: In children with MTHI in an IR group, clinicians prefer clinical observation above performing a CT scan. Older age, day of presentation, and any loss of consciousness are factors associated with a CT scan. WHAT IS KNOWN: ⢠Clinical decision rules have been developed in the management of children of different risk groups with minor traumatic head injury (MTHI). ⢠According to the Dutch national, clinical decision rules in children under 6 years of age up to 50% of children classify as intermediate risk (IR) and clinicians may choose between clinical observation and computed tomography (CT). WHAT IS NEW: ⢠In this IR group, clinical observation is chosen in 81% children with MTHI. ⢠In the subgroup where clinicians performed a CT scan, children were older and presented more frequently on a weekend day, and more frequently consciousness was lost.

OBJECTIVE: The purpose of this study was to estimate the time to recovery of command-following and associations between hypoxemia with time to recovery of command-following. METHODS: In this multicenter, retrospective, cohort study during the initial surge of the United States' pandemic (March-July 2020) we estimate the time from intubation to recovery of command-following, using Kaplan Meier cumulative-incidence curves and Cox proportional hazard models. Patients were included if they were admitted to 1 of 3 hospitals because of severe coronavirus disease 2019 (COVID-19), required endotracheal intubation for at least 7 days, and experienced impairment of consciousness (Glasgow Coma Scale motor score <6). RESULTS: Five hundred seventy-one patients of the 795 patients recovered command-following. The median time to recovery of command-following was 30 days (95% confidence interval [CI] = 27-32 days). Median time to recovery of command-following increased by 16 days for patients with at least one episode of an arterial partial pressure of oxygen (PaO2 ) value ≤55 mmHg (p < 0.001), and 25% recovered ≥10 days after cessation of mechanical ventilation. The time to recovery of command-following was associated with hypoxemia (PaO2 ≤55 mmHg hazard ratio [HR] = 0.56, 95% CI = 0.46-0.68; PaO2 ≤70 HR = 0.88, 95% CI = 0.85-0.91), and each additional day of hypoxemia decreased the likelihood of recovery, accounting for confounders including sedation. These findings were confirmed among patients without any imagining evidence of structural brain injury (n = 199), and in a non-overlapping second surge cohort (N = 427, October 2020 to April 2021). INTERPRETATION: Survivors of severe COVID-19 commonly recover consciousness weeks after cessation of mechanical ventilation. Long recovery periods are associated with more severe hypoxemia. This relationship is not explained by sedation or brain injury identified on clinical imaging and should inform decisions about life-sustaining therapies. ANN NEUROL 2022;91:740-755.

A 50-year-old man who worked as a helicopter rescue pilot transiently lost consciousness while piloting a helicopter rescue. In the diagnostic process, all tests for the main possible differential diagnoses of loss of consciousness (cardiological and neurological) were performed and yielded normal results. Blood chemistry tests revealed recurrent fasting hypoglycemia and Chromogranin A was at the upper limit of normal. Fine needle aspiration guided by endoscopic ultrasonography was used to diagnose insulinoma-type neuroendocrine tumor of the pancreas. According to the Italian policies, the occupational physician aims to maintain professional skills without neglecting flight safety. A careful analysis of the relationship between the characteristics of the state of health of the aviator and his specific work needs was carried out, and he was given the opportunity to continue working as a rescue pilot thanks to medical therapies associated with organizational interventions in the workplace.

It can be difficult for anesthesiologists to determine the optimal dose of propofol for end-stage kidney disease (ESKD) patients due to changes in drug disposition. The purpose of this study was to evaluate the potency of propofol for inducing loss of consciousness in ESKD patients. Patients with normal kidney function (Control group, n = 15), those with ESKD (ESKD group, n = 15), and those with ESKD undergoing cervical epidural anesthesia (ESKD-CEB group, n = 15) were administered propofol by target-controlled infusion (TCI) using the Schneider model. The effect-site concentration (Ce) of propofol started at 0.5 µg/ml and increased in increments of 0.5 µg/ml until the patient did not respond to verbal commands. The relationship between the probability (P) of loss of consciousness and the Ce of propofol was analyzed in each group using logistic regression. The Ce values of propofol at the time of loss of consciousness were 4.3 ± 0.9, 3.7 ± 0.9, and 3.3 ± 1.0 µg/ml for the Control, ESKD, and ESKD-CEB* groups, respectively (*significant difference vs. control, P < 0.05). The estimated Ce50 values for lost ability to respond to verbal command were 4.56, 3.75, and 3.21 µg/ml for the Control, ESKD, and ESKD-CEB groups, respectively. In conclusion, when inducing anesthesia in ESKD patients, we recommend using an initial dose similar to that of patients with normal kidney function, or rather starting with a lower dose.
