Objectives: The COVID-19 pandemic has been a serious worldwide public health crisis since 2020 and is still challenging healthcare systems. New tools for the prognosis and diagnosis of COVID-19 patients remain important issues. Design: Here, we studied the metabolome of plasma samples of COVID-19 patients for the identification of prognosis biomarkers. Patients: Plasma samples of eighty-six SARS-CoV-2-infected subjects and 24 healthy controls were collected during the first peak of the COVID-19 pandemic in France in 2020. Main results: Plasma metabolome fingerprinting allowed the successful discrimination of healthy controls, mild SARS-CoV-2 subjects, and moderate and severe COVID-19 patients at hospital admission. We found a strong effect of SARS-CoV-2 infection on the plasma metabolome in mild cases. Our results revealed that plasma lipids and alterations in their saturation level are important biomarkers for the detection of the infection. We also identified deoxy-fructosyl-amino acids as new putative plasma biomarkers for SARS-CoV-2 infection and COVID-19 severity. Finally, our results highlight a key role for plasma levels of tryptophan and kynurenine in the symptoms of COVID-19 patients. Conclusion: Our results showed that plasma metabolome profiling is an efficient tool for the diagnosis and prognosis of SARS-CoV-2 infection.
ABSTRACT
BACKGROUND: Reports published directly after terrorist mass casualty incidents frequently fail to capture difficulties that may have been encountered. An anonymised consensus-based platform may enable discussion and collaboration on the challenges faced. Our aim was to identify where to focus improvement for future responses. METHODS: We conducted a mixed methods study by email of clinicians' experiences of leading during terrorist mass casualty incidents. An initial survey identified features that worked well, or failed to, during terrorist mass casualty incidents plus ongoing challenges and changes that were implemented as a result. A follow-up, quantitative survey measured agreement between responses within each of the themes using a Likert scale. RESULTS: Thirty-three participants responded from 22 hospitals that had received casualties from a terrorist incident, representing 17 cities in low-middle, middle and high income countries. The first survey identified themes of sufficient (sometimes abundant) human resource, although coordination of staff was a challenge. Difficulties highlighted were communication, security, and management of blast injuries. The most frequently implemented changes were education on specific injuries, revising future plans and preparatory exercises. Persisting challenges were lack of time allocated to training and psychological well-being. The follow-up survey recorded highest agreement amongst correspondents on the need for re-triage at hospital (90% agreement), coordination roles (85% agreement), flexibility (100% agreement), and large-scale exercises (95% agreement). CONCLUSION: This survey collates international experience gained from clinicians managing terrorist mass casualty incidents. The organisation of human response, rather than consumption of physical supplies, emerged as the main finding. NHSH Clinical Effectiveness Unit project registration number: 2020/21-036.

OBJECTIVES: We aimed to evaluate the effectiveness of a multifaceted procedure in improving pneumococcal and influenza vaccinations 6 months after an emergency department (ED) visit among patients aged 65 years and older. METHODS: We conducted a cluster-randomized, controlled, parallel-group, open-label implementation trial in 18 EDs in France and Monaco. Participants were recruited from November 2015 to September 2016. EDs were randomly assigned with a 1:1 ratio to provide either a multifaceted procedure that combined structured information about pneumococcal and influenza vaccines and three text message reminders sent to patients every two weeks (intervention arm) or nonstructured information only (control arm). The outcomes were self-reported pneumococcal vaccination and influenza vaccination rates within 6 months of enrollment. RESULTS: A total of 9 EDs were randomized to the intervention arm (n = 780 patients) and 9 to the control arm (n = 695 patients). The median age for all enrolled patients was 74 years (25-75th percentiles, 69 to 82): 50.1% were male, 34.9% had at least one underlying condition, and 30.7% were at risk for invasive pneumococcal infection. In the intention-to-treat analysis, the multifaceted intervention did not alter the pneumococcal vaccination rate (6.4% versus 4.6%, absolute difference: 1.8; 95% CI: [-0.9 to 4.4]; p = 0.19), whereas it improved the influenza vaccination rate (52.1% versus 40.0%, absolute difference: 12.1; 95% CI: [2.4 to 21.8]; p = 0.01). At 12 months, mortality did not differ between the intervention (9.7%) and control (11.2%) arms (p = 0.35). CONCLUSIONS: A multifaceted intervention based on text message reminders provides an opportunity to increase anti-influenza vaccination among elderly patients visiting the ED. Efforts are warranted to provide better information on pneumococcal diseases and the benefits of pneumococcal vaccines, especially in the elderly.
ABSTRACT
The variant 20I/501Y.V1, associated to a higher risk of transmissibility, emerged in Nice city (Southeast of France, French Riviera) during January 2021. The pandemic has resumed late December 2020 in this area. A high incidence rate together with a fast turn-over of the main circulating variants, provided us the opportunity to analyze modifications in clinical profile and outcome traits. We performed an observational study in the University hospital of Nice from December 2020 to February 2021. We analyzed data of sequencing of SARS-CoV-2 from the sewage collector and PCR screening from all positive samples at the hospital. Then, we described the characteristics of all COVID-19 patients admitted in the emergency department (ED) (n = 1247) and those hospitalized in the infectious diseases ward or ICU (n = 232). The UK-variant was absent in this area in December, then increasingly spread in January representing 59% of the PCR screening performed mid-February. The rate of patients over 65 years admitted to the ED decreased from 63 to 50% (p = 0.001). The mean age of hospitalized patients in the infectious diseases ward decreased from 70.7 to 59.2 (p < 0.001) while the proportion of patients without comorbidity increased from 16 to 42% (p = 0.007). Spread of the UK-variant in the Southeast of France affects younger and healthier patients.

PURPOSE: Point-of-care ultrasound using a pocket-ultrasound-device (PUD) is increasing in clinical medicine but the optimal way to teach focused cardiac ultrasound is not clear. We evaluated whether teaching using a PUD or a conventional-ultrasound-device (CUD) is different when the final exam was conducted on a PUD. The primary aim was to compare the weighted total quality scale (WTQS, out of 100) obtained by participants in the two groups (CUD and PUD) on a live volunteer 2-4 weeks after their initial training. The secondary aims were to compare examination time and students' confidence levels (out of 50). METHODS: This bicentric, prospective single-blind randomized trial included undergraduate medical students. After watching a 15 min video about echocardiography views, students had a 45 min hands-on training session with a live volunteer using a PUD or a CUD. The final examination was conducted with a PUD on a live volunteer. RESULTS: Eighty-six comparable students were included, with 4 ± 1 years of medical training. In the PUD group, the mean WTQS was 65 ± 16 versus 60 ± 15 in the CUD group [p = 0.22; in multivariate analysis, OR 0.8 95% CI (0.1;1.6), p = 0.34]. The examination time was 10.0 [6.2-12.4] min in the PUD group versus 11.4 [7.3-13.2] in the CUD group (p = 0.39), while the confidence level was 27.9 ± 7.7 in the PUD group versus 27.4 ± 7.2 in the CUD group (p = 0.76). CONCLUSION: There was no difference between teaching echocardiographic views using a PUD as compared to a CUD on the PUD image quality, exam time, or confidence level of students.

Background Recent literature reports a strong thrombotic tendency in patients hospitalized for a coronavirus disease 2019 (COVID-19) infection. This characteristic is unusual and seems specific to COVID-19 infections, especially in their severe form. Viral infections can trigger acquired thrombophilia, which can then lead to thrombotic complications. We investigate for the presence of acquired thrombophilia, which could participate in this phenomenon, and report its prevalence. We also wonder if these thrombophilias participate in the bad prognosis of severe COVID-19 infections. Methods and Results In 89 consecutive patients hospitalized for COVID-19 infection, we found a 20% prevalence of PS (protein S) deficiency and a high (ie, 72%) prevalence of antiphospholipid antibodies: mainly lupus anticoagulant. The presence of PS deficiency or antiphospholipid antibodies was not linked with a prolonged activated partial thromboplastin time nor with D-dimer, fibrinogen, or CRP (C-reactive protein) concentrations. These coagulation abnormalities are also not linked with thrombotic clinical events occurring during hospitalization nor with mortality. Conclusions We assess a high prevalence of positive tests detecting thrombophilia in COVID-19 infections. However, in our series, these acquired thrombophilias are not correlated with the severity of the disease nor with the occurrence of thrombotic events. Albeit the strong thrombotic tendency in COVID-19 infections, the presence of frequent acquired thrombophilia may be part of the inflammation storm of COVID-19 and should not systematically modify our strategy on prophylactic anticoagulant treatment, which is already revised upwards in this pathological condition.

Association between Hydroxychloroquine (HCQ) and Azithromycin (AZT) is under evaluation for patients with lower respiratory tract infection (LRTI) caused by the Severe Acute Respiratory Syndrome (SARS-CoV-2). Both drugs have a known torsadogenic potential, but sparse data are available concerning QT prolongation induced by this association. Our objective was to assess for COVID-19 LRTI variations of QT interval under HCQ/AZT in patients hospitalized, and to compare manual versus automated QT measurements. Before therapy initiation, a baseline 12 lead-ECG was electronically sent to our cardiology department for automated and manual QT analysis (Bazett and Fridericia's correction), repeated 2 days after initiation. According to our institutional protocol (Pasteur University Hospital), HCQ/AZT was initiated only if baseline QTc ≤ 480ms and potassium level> 4.0 mmol/L. From March 24th to April 20th 2020, 73 patients were included (mean age 62 ± 14 years, male 67%). Two patients out of 73 (2.7%) were not eligible for drug initiation (QTc ≥ 500 ms). Baseline average automated QTc was 415 ± 29 ms and lengthened to 438 ± 40 ms after 48 hours of combined therapy. The treatment had to be stopped because of significant QTc prolongation in two out of 71 patients (2.8%). No drug-induced life-threatening arrhythmia, nor death was observed. Automated QTc measurements revealed accurate in comparison with manual QTc measurements. In this specific population of inpatients with COVID-19 LRTI, HCQ/AZT could not be initiated or had to be interrupted in less than 6% of the cases.

Cruise tourism to Antarctica is constantly growing. Passengers and crewmembers may experience illnessesor injuries while traveling to remote areas with harsh weather conditions from where prompt evacuationis mostly unavailable. While a small explorer ship was at Wilhelmina bay (64°39' South and 62°08' West)in the Antarctic Peninsula, a 73-year-old male passenger presented with acute chest pain after two shortexcursions off the vessel in cold weather conditions. He was treated on board and remained clinicallystable until the ship reached Ushuaia at the end of the cruise which was 5 days after the symptoms onset.

OBJECTIVES: An accurate diagnosis of sepsis in the emergency department must be made before appropriate treatment can be started. Many biomarkers that are potentially useful have been studied. The main aim of this study was to compare the diagnostic accuracy of blood levels of presepsin, lactate, C-reactive protein (CRP), and procalcitonin (PCT) for predicting sepsis as defined by the Sepsis-3 criteria. The secondary aim was to evaluate the diagnostic accuracy of these biomarkers for predicting bacteremia whether or not sepsis or septic shock was present. MATERIAL AND METHODS: Single-center, prospective, observational cohort study in the emergency department of a university hospital. Consecutive patients suspected of having infection were enrolled prospectively if they had at least 2 criteria for systemic inflammatory response syndrome. We measured presepsin, PCT, CRP, and lactate in blood extracted on admission. RESULTS: Blood samples from 359 patients were analyzed; 228 (63.5%) met the criteria for sepsis and 20 (5.6%) met the criteria for septic shock. PCT and presepsin levels were the best predictors of sepsis and septic shock with areas under the receiver operating characteristic curve (AUC) of 0.711 (95% CI, 0.660-0.758) and 0.709 (95% CI, 0.658- 0.756), respectively (P <.001, both comparisons). The AUCs for CRP and lactate concentrations were, respectively, 0.63 (95% CI, 0.58-0.69) and 0.61 (95% CI, 0.56-0.66) (P <.05, both comparisons). On applying the diagnostic cut points of 0.25 ng/mL for PCT and 500 pg/mL for presepsin, the odds ratios were 2.51 (95% CI, 1.53-4.12) for PCT and 3.19 (95% CI, 1.91-5.31) for presepsin. The diagnostic accuracy of the combination of presepsin and PCT results (AUC, 0.71; 95% CI 0.66-0.76; P <.001) was no better than the accuracy of PCT alone. The most accurate predictor of bacteremia was PCT (AUC, 0.835; 95% CI, 0.79-0.87; P <.001). CONCLUSION: Presepsin and PCT seem to be the best predictors of a diagnosis of sepsis or septic shock in emergency department patients.
OBJETIVO: El diagnóstico correcto de la sepsis en urgencias es clave para iniciar el tratamiento de forma adecuada. Para ello, se han estudiado múltiples biomarcadores que podrían ser de utilidad. El objetivo principal de este estudio fue evaluar la capacidad diagnóstica de presepsina en sangre, en comparación con procalcitonina (PCT), proteína C reactiva (PCR) y lactato, para predecir sepsis o shock séptico según la definición de Sepsis-3. El objetivo secundario fue valorar la capacidad de estos biomarcadores para predecir bacteriemia, independientemente del diagnóstico final de sepsis o shock séptico. METODO: Estudio prospectivo de cohorte observacional, realizado en un único servicio de urgencias (SU) de un hospital universitario. Se incluyeron pacientes con sospecha clínica de infección y al menos dos criterios de síndrome de respuesta inflamatoria sistémica. En todos los pacientes se determinó en sangre presepsina, PCT, PCR y lactato en el momento de la visita en el SU. RESULTADOS: Se analizaron 359 pacientes, de los que 228 (63,5%) presentaban criterios de sepsis y 20 (5,6%) de shock séptico. PCT y presepsina fueron los mejores biomarcadores para predecir la sepsis/shock séptico con un área bajo la curva (ABC) de la capacidad operativa del receptor (ROC) de 0,711 (IC 95% 0,660-0,758; p < 0,001) y 0,709 (IC 95% 0,658-0,756; p < 0,001). La PCR obtuvo una ABC de 0,635 (IC 95% 0,582-0,686; p < 0,05), y el lactato una ABC de 0,61 (IC 95% 0,556-0,661; p < 0,05). Se utilizó un punto de decisión de 0,25 ng/ml para PCT y de 500 pg/ ml para presepsina. La odds ratio de presepsina para predecir sepsis fue de 3,19 (IC 95% 1,91-5,31) y para PCT de 2,51 (IC 95% 1,53-4,12). El diagnóstico de sepsis/shock séptico no mejoró al combinar presepsina y PCT (el ABC-ROC fue de 0,714, IC 95% 0,66-0,76; p < 0,001) en comparación con PCT aislada. La PCT fue el predictor más preciso de bacteriemia en pacientes con infección con un ABC-ROC de 0,835 (IC 95% 0,79-0,87; p < 0,001). CONCLUSIONES: La presepsina y la PCT son los biomarcadores con mejor rendimiento para el diagnóstico de sepsis y shock séptico en el SU.

Metabolic acidosis is a disorder frequently encountered in emergency medicine and intensive care medicine. As literature has been enriched with new data concerning the management of metabolic acidosis, the French Intensive Care Society (Société de Réanimation de Langue Française [SRLF]) and the French Emergency Medicine Society (Société Française de Médecine d'Urgence [SFMU]) have developed formalized recommendations from experts using the GRADE methodology. The fields of diagnostic strategy, patient assessment, and referral and therapeutic management were addressed and 29 recommendations were made: 4 recommendations were strong (Grade 1), 10 were weak (Grade 2), and 15 were experts' opinions. A strong agreement from voting participants was obtained for all recommendations. The application of Henderson-Hasselbalch and Stewart methods for the diagnosis of the metabolic acidosis mechanism is discussed and a diagnostic algorithm is proposed. The use of ketosis and venous and capillary lactatemia is also treated. The value of pH, lactatemia, and its kinetics for the referral of patients in pre-hospital and emergency departments is considered. Finally, the modalities of insulin therapy during diabetic ketoacidosis, the indications for sodium bicarbonate infusion and extra-renal purification as well as the modalities of mechanical ventilation during severe metabolic acidosis are addressed in therapeutic management.

The goal of our study was to determine if an intranasal (IN) dose of sufentanil delivered in the ED triage zone would improve the management of severely painful patients. We performed a randomized, double blind and placebo-controlled trial on adult patients suffering from an acute severe pain (≥ 6/10) consecutive to an isolated limb injury. We compared 2 analgesic strategies: the usual pain treatment with IV-only multimodal analgesics (IVMA) including IV opioids if needed (control group) and another strategy (active group) based on a single dose of IN sufentanil (0.4 µg/kg) given at triage and followed by IV multimodal analgesia. Our primary outcome was the proportion of patients reaching pain-relief (≤ 3/10) 30 min after IN injection at triage. Secondary outcomes were rates of adverse events, frequency of clinical interventions required by these events, and satisfaction of patients. A total of 144 adult participants completed the study, 72 in each group. Compared with usual IV-only pain management, the analgesic strategy initiated in triage zone with a dose of IN sufentanil increased the proportion of patients reaching pain relief in 30 min: 72.2% versus 51.4%, in our trial (p = 0.01 and number needed to treat of 5). There was no serious adverse event (AE) in both groups. Patients who received IN sufentanil experienced more frequently minor opiate side effects. Proportion of respiratory AEs was higher in the active group (12.5% of bradypnea < 10 cycles per minute versus 1.4%) but these events were of mild severity, as only 2 participants (one in each group) received temporary low dose oxygen therapy, and none required naloxone. Lengths of stay in the ED were similar in both groups, as well as satisfaction of patients (above 9/10) and pain scores at discharge (< 2/10). We found that a single dose of IN sufentanil delivered in the ED triage zone significantly increases the proportion of severely painful patients reaching painrelief in 30 min, compared to usual analgesia with IV-only multimodal analgesia.

We evaluate in this retrospective cohort, the clinical situations leading emergency physicians to take a blood lactate sample, the prevalence of hyperlactatemia and its impact on short-term adverse outcome. ED patients requiring a blood lactate measurement (BLM) during a two-year period were included. Early patients' outcomes were extracted and discharge diagnoses were classified into 12 diagnostic categories. A total of 118,737 patients were analyzed. A BLM was carried out in 13,089 of them. Surprisingly, the proportion of patients having a BLM was higher in those admitted for seizure (31.4%) than in those admitted for infection (27.9%). Ten percent of patients who had a blood lactate test had a lactate level >4â¯mmol/l (1,315). Among them, 23.2% were admitted for infections, 20% for seizures, and 11% for cardiovascular diseases. After excluding the patients older than 75â¯years from the analysis in order to prevent a selection bias, the patient's severity was independently associated to an age over 65â¯years (OR: 1.26), an arterial blood sampling (OR: 2.77) and the blood lactate level (OR: 1.31). The blood lactate level was very informative to detect the sicker patients in the infection group whereas its interest was poor in the group of patients admitted for seizures. In conclusion, blood lactate testing has become routine in emergency departments and a large proportion of patients have abnormal blood lactate levels. The most frequent causes of high blood lactate in the ED are infection and seizures but the prognostic value of blood lactate seems to be different from one diagnostic category to the other.

BACKGROUND: Navigations on cruise ships are rising and tend to spread to remote areas like polar regions. Our aim was to assess the prevalence of pathologies encountered on a cruise ship navigating in remote areas including Polar Seas. MATERIALS AND METHODS: A prospective observational, descriptive and cross-sectional study was conducted aboard a cruise ship with an overall capacity of 200-264 passengers and 140 crewmembers, sailing in remote areas as the Arctic Ocean and the Antarctic Peninsula over a period of 205 days. The database was built on all first consultations for passengers and crewmembers done by the onboard physician. Each symptom and diagnosis was coded according to the "International Classification of Primary Care, 2nd edition". For statistical analysis, the quantitative data were expressed as mean ± standard deviation and qualitative data as percentages. The percentages were compared using a c2 test corrected according to the Yates' method or by a Fisher test when appropriate. RESULTS: A total of 446 diagnoses were studied on the 910 consultations originally included (13.7% of the people on board). The median age for the passengers and the crewmembers was respectively 68 (age ranging from 12 to 90) years and 31 (18-62) years. Likewise, the sex ratio (male/female) was 0.98 and 3.23. Infectious diseases were predominant (prevalence of 43.7%). Among them, respiratory infections were the most common and gastroenteritis seemed to be more frequent in passengers (prevalence of 11.5% vs. 5%, p = 0.10). Cutaneous pathologies were more frequent in crewmembers (prevalence of 26.6% vs. 18.7%, p = 0.04) and allergic dermatitis was the second most frequent in this group of patients (prevalence of 7.2%). Cardiovascular diseases, more common in passengers (p = 0.05), represented 4% of all diagnoses. Two cases of phlebitis, one stroke and one subacute heart failure were diagnosed. Among traumatic injuries, cutaneous traumas were the commonest (prevalence of 76.5%). Musculoskeletal traumas were more common in passengers (p = 0.04). An acute gastrointestinal haemorrhage required a medical evacuation from the Antarctic Peninsula. CONCLUSIONS: The physician should be prepared to face emergency cases by developing personal expertise specific to maritime medicine in remote areas. Highlighting the particularity of cases handled in remote areas, our results should also pave the way of the development of medical protocols for ships lacking physician.
