RESUMO
OBJECTIVES: The objective was to define a safe strategy to exclude pulmonary embolism (PE) in COVID-19 outpatients, without performing CT pulmonary angiogram (CTPA). METHODS: COVID-19 outpatients from 15 university hospitals who underwent a CTPA were retrospectively evaluated. D-Dimers, variables of the revised Geneva and Wells scores, as well as laboratory findings and clinical characteristics related to COVID-19 pneumonia, were collected. CTPA reports were reviewed for the presence of PE and the extent of COVID-19 disease. PE rule-out strategies were based solely on D-Dimer tests using different thresholds, the revised Geneva and Wells scores, and a COVID-19 PE prediction model built on our dataset were compared. The area under the receiver operating characteristics curve (AUC), failure rate, and efficiency were calculated. RESULTS: In total, 1369 patients were included of whom 124 were PE positive (9.1%). Failure rate and efficiency of D-Dimer > 500 µg/l were 0.9% (95%CI, 0.2-4.8%) and 10.1% (8.5-11.9%), respectively, increasing to 1.0% (0.2-5.3%) and 16.4% (14.4-18.7%), respectively, for an age-adjusted D-Dimer level. D-dimer > 1000 µg/l led to an unacceptable failure rate to 8.1% (4.4-14.5%). The best performances of the revised Geneva and Wells scores were obtained using the age-adjusted D-Dimer level. They had the same failure rate of 1.0% (0.2-5.3%) for efficiency of 16.8% (14.7-19.1%), and 16.9% (14.8-19.2%) respectively. The developed COVID-19 PE prediction model had an AUC of 0.609 (0.594-0.623) with an efficiency of 20.5% (18.4-22.8%) when its failure was set to 0.8%. CONCLUSIONS: The strategy to safely exclude PE in COVID-19 outpatients should not differ from that used in non-COVID-19 patients. The added value of the COVID-19 PE prediction model is minor. KEY POINTS: ⢠D-dimer level remains the most important predictor of pulmonary embolism in COVID-19 patients. ⢠The AUCs of the revised Geneva and Wells scores using an age-adjusted D-dimer threshold were 0.587 (95%CI, 0.572 to 0.603) and 0.588 (95%CI, 0.572 to 0.603). ⢠The AUC of COVID-19-specific strategy to rule out pulmonary embolism ranged from 0.513 (95%CI: 0.503 to 0.522) to 0.609 (95%CI: 0.594 to 0.623).

BACKGROUND: At the end of 2021, the B.1.1.529 SARS-CoV-2 variant (Omicron) wave superseded the B.1.617.2 variant (Delta) wave. OBJECTIVE: To compare baseline characteristics and in-hospital outcomes of patients with SARS-CoV-2 infection with the Delta variant versus the Omicron variant in the emergency department (ED). DESIGN: Retrospective chart reviews. SETTING: 13 adult EDs in academic hospitals in the Paris area from 29 November 2021 to 10 January 2022. PATIENTS: Patients with a positive reverse transcriptase polymerase chain reaction (RT-PCR) test result for SARS-CoV-2 and variant identification. MEASUREMENTS: Main outcome measures were baseline clinical and biological characteristics at ED presentation, intensive care unit (ICU) admission, mechanical ventilation, and in-hospital mortality. RESULTS: A total of 3728 patients had a positive RT-PCR test result for SARS-CoV-2 during the study period; 1716 patients who had a variant determination (818 Delta and 898 Omicron) were included. Median age was 58 years, and 49% were women. Patients infected with the Omicron variant were younger (54 vs. 62 years; difference, 8.0 years [95% CI, 4.6 to 11.4 years]), had a lower rate of obesity (8.0% vs. 12.5%; difference, 4.5 percentage points [CI, 1.5 to 7.5 percentage points]), were more vaccinated (65% vs. 39% for 1 dose and 22% vs. 11% for 3 doses), had a lower rate of dyspnea (26% vs. 50%; difference, 23.6 percentage points [CI, 19.0 to 28.2 percentage points]), and had a higher rate of discharge home from the ED (59% vs. 37%; difference, 21.9 percentage points [-26.5 to -17.1 percentage points]). Compared with Delta, Omicron infection was independently associated with a lower risk for ICU admission (adjusted difference, 11.4 percentage points [CI, 8.4 to 14.4 percentage points]), mechanical ventilation (adjusted difference, 3.6 percentage points [CI, 1.7 to 5.6 percentage points]), and in-hospital mortality (adjusted difference, 4.2 percentage points [CI, 2.0 to 6.5 percentage points]). LIMITATION: Patients with COVID-19 illness and no SARS-CoV-2 variant determination in the ED were excluded. CONCLUSION: Compared with the Delta variant, infection with the Omicron variant in patients in the ED had different clinical and biological patterns and was associated with better in-hospital outcomes, including higher survival. PRIMARY FUNDING SOURCE: None.

BACKGROUND: Viral respiratory tract infections (VRTIs) are among the most common diseases, but the risks of superinfection for different virus species have never been compared. METHODS: Multicenter retrospective study conducted among adults who tested positive for VRTIs with reverse-transcription polymerase chain reaction. We compared characteristics between influenza (A or B) and paramyxoviruses (respiratory syncytial virus, parainfluenza virus types 1 and 3, and human metapneumovirus) and identified predictors of superinfection and hospitalization.s. RESULTS: Five hundred ninety patients had VRTI, including 347 (59%) influenza and 243 paramyxovirus infections with comparable rates of superinfections (53% vs 60%). In multivariate analyses, the predictors of superinfections were ageâ >75 years (adjusted odds ratio,â 2.37 [95% confidence interval, 1.65-3.40]), chronic respiratory disease (1.79 [1.20-2.67]), and biological abnormalities, including neutrophil countâ >7000/µL (1.98 [1.34-2.91)], eosinophil countâ <50/µL (2.53 [1.61-3.98], and procalcitonin levelâ >0.25ng/mL (2.8 [1.65-4.73]). The predictors of hospitalization were ageâ >75 years old (adjusted odds ratio,â 3.49 [95% confidence interval, 2.17-5.63]), paramyxovirus infection (2.28 [1.39-3.75]), long-term use of inhaled corticosteroids (2.49 [1.13-5.49]), and biological abnormalities, including neutrophil countâ >7000/µL (2.38 [1.37-4.12)] and procalcitonin level >0.25ng/mL (2.49 [1.23-5.02]). Kaplan-Meier survival curves showed that influenza-infected patients had a higher mortality rate than those with paramyxovirus infections (8.9% vs 4.5%, respectively; Pâ =â .02). CONCLUSIONS: Our study revealed a high rate of superinfection (56%), not related to viral species. However influenza virus was associated with a poorer prognosis than paramyxoviruses, pleading for a broader and large-scale vaccination of individual at risk of VRTIs.

Data whether the COVID-19 outbreak impacts the acute coronary syndromes (ACS) admissions and the time required to reverse the downward curve are scarce. We included all consecutive patients referred for an ACS who underwent PCI from February 17, 2020 to April 26, 2020 in a high-volume PCI coronary care unit. We compared the number of ACS patients in 2020 to the same period in 2018 and 2019. Predictors of adverse outcome in ST-elevation myocardial infarction (STEMI) patients were recorded: symptom-onset-to-first medical contact (FMC), and FMC-to-sheath insertion times. During the studied period (calendar weeks 8-17, 2018-2020), 144 ACS patients were included. In 2020, we observed two distinct phases in the ACS admissions: a first significant fall, with a relative reduction of 73%, from the week of lockdown (week 12) to 3 weeks later and then an increase of ACS. Median symptom-onset-to-FMC time was significantly higher in 2020 than in the two previous years (600 min [298-632] versus 121 min [55-291], p < 0.001). Median FMC-to-sheath insertion did not differ significantly (93 min [81-131] in 2020 versus 90 min [67-137] in 2018-2019, p = 0.57). The main findings are (1) a pattern of a U-curve in ACS admissions, with a first decrease in ACS admissions and a return to "normality" 4 weeks after; (2) a significant increase in the total ischemic time exclusively due to an increase in the symptom-onset-to-first-medical-contact time.

Recent reports have suggested an increased risk of pulmonary embolism (PE) related to COVID-19. The aim of this cohort study is to compare the incidence of PE during a 3-year period and to assess the characteristics of PE in COVID-19. We studied consecutive patients presenting with PE (January 2017-April 2020). Clinical presentation, computed tomography (CT) and biological markers were systematically assessed. We recorded the global number of hospitalizations during the COVID-19 pandemic and during the same period in 2018-2019. We included 347 patients: 326 without COVID-19 and 21 with COVID-19. Patients with COVID-19 experienced more likely dyspnea (p=0.04), had lower arterial oxygen saturation (p<0.001), higher C-reactive protein and white blood cell (WBC) count (p<0.0001 and p=0.001, respectively), and a significantly higher in-hospital mortality (14% versus 3.4%, p=0.04). Among COVID-19 patients, diagnosis of PE was performed at admission in 38% (n=8). COVID-19 patients with diagnosis of PE during hospitalization (n=13) had significantly more dyspnea (p=0.04), lower arterial oxygen saturation (p=0.01), less proximal PE (p=0.02), and higher heart rate (p=0.009), CT severity score (p=0.001), C-reactive protein (p=0.006) and WBC count (p=0.04). During the COVID-19 outbreak, a 97.4% increase of PE incidence was observed as compared to 2017-2019 and the proportion of hospitalizations related to PE was 3.7% versus 1.3% in 2018-2019 (p<0.0001). In conclusion, the COVID-19 pandemic leads to a dramatic increased incidence of PE. Physicians should be aware that PE may be diagnosed at admission, but also after several days of hospitalization, with a different clinical, CT and biological features of thrombotic disease.

AIMS: To assess recommendations provided by the EXtracorporeal TReatments In Poisoning (EXTRIP) workgroup on extracorporeal toxin removal (ECTR) in lithium poisoning. METHODS: Retrospective assessment in a 128 lithium-poisoned patient cohort previously used to identify ECTR initiation criteria that could improve outcome (Paris criteria). ECTR requirement using EXTRIP criteria was compared to the actual practice or if Paris criteria were used. The potential impact on outcome if these different criteria were used was investigated. RESULTS: Using the recommended (Rec-EXTRIP) or recommended + suggested (All-EXTRIP) EXTRIP criteria, ECTR would have been indicated in more patients than was actually done (P < .001), or if Paris criteria were used (P < .01). The non-actually ECTR-treated patients fulfilling Rec-EXTRIP or All-EXTRIP criteria had shorter intensive care unit stay (P < .05) and no significant increase in fatalities and neurological impairment on discharge in comparison to the actually ECTR-treated patients. ECTR requirements using EXTRIP vs Paris criteria were not concordant (P < .001). In the non-actually ECTR-treated patients, 31/106 and 55/106 patients fulfilled Rec-EXTRIP or All-EXTRIP but not Paris criteria, respectively. Those patients had longer stay (P < .01) but no worse neurological impairment on discharge than the patients not fulfilling any of these criteria (50/106 and 26/106, respectively). In the non-actually ECTR-treated patients, 7/106 fulfilled Paris but not Rec-EXTRIP criteria. Those patients had longer stay (P < .05) and worse neurological impairment on discharge (P < .01) than the 50/106 patients not fulfilling any of these criteria. CONCLUSION: In this cohort of lithium poisonings, EXTRIP criteria may lead to more ECTR than actually performed or if the Paris criteria were used, with no demonstrated improvement in outcome.

Importance: Clinical guidelines for the early management of acute heart failure in the emergency department (ED) setting are based on only moderate levels of evidence, with subsequent low adherence to these guidelines. Objective: To test the effect of an early guideline-recommended care bundle on short-term prognosis in older patients with acute heart failure in the ED. Design, Setting, and Participants: Stepped-wedge cluster randomized trial in 15 EDs in France of 503 patients 75 years and older with a diagnosis of acute heart failure in the ED from December 2018 to September 2019 and followed up for 30 days until October 2019. Interventions: A care bundle that included early intravenous nitrate boluses; management of precipitating factors, such as acute coronary syndrome, infection, or atrial fibrillation; and moderate dose of intravenous diuretics (n = 200). In the control group, patient care was left to the discretion of the treating emergency physician (n = 303). Each center was randomized to the order in which they switched to the "intervention period." After the initial 4-week control period for all centers, 1 center entered in the intervention period every 2 weeks. Main Outcomes and Measures: The primary end point was the number of days alive and out of hospital at 30 days. Secondary outcomes included 30-day all-cause mortality, 30-day cardiovascular mortality, unscheduled readmission, length of hospital stay, and kidney impairment. Results: Among 503 patients who were randomized (median age, 87 years; 298 [59%] women), 502 were analyzed. In the intervention group, patients received a median (interquartile range) of 27.0 (9-54) mg of intravenous nitrates in the first 4 hours vs 4.0 (2.0-6.0) mg in the control group (adjusted difference, 23.8 [95% CI, 13.5-34.1]). There was a significantly higher percentage of patients in the intervention group treated for their precipitating factors than in the control group (58.8% vs 31.9%; adjusted difference, 31.1% [95% CI, 14.3%-47.9%]). There was no statistically significant difference in the primary end point of the number of days alive and out of hospital at 30 days (median [interquartile range], 19 [0- 24] d in both groups; adjusted difference, -1.9 [95% CI, -6.6 to 2.8]; adjusted ratio, 0.88 [95% CI, 0.64-1.21]). At 30 days, there was no significant difference between the intervention and control groups in mortality (8.0% vs 9.7%; adjusted difference, 4.1% [95% CI, -17.2% to 25.3%]), cardiovascular mortality (5.0% vs 7.4%; adjusted difference, 2.1% [95% CI, -15.5% to 19.8%]), unscheduled readmission (14.3% vs 15.7%; adjusted difference, -1.3% [95% CI, -26.3% to 23.7%]), median length of hospital stay (8 d in both groups; adjusted difference, 2.5 [95% CI, -0.9 to 5.8]), and kidney impairment (1% in both groups). Conclusions and Relevance: Among older patients with acute heart failure, use of a guideline-based comprehensive care bundle in the ED compared with usual care did not result in a statistically significant difference in the number of days alive and out of the hospital at 30 days. Further research is needed to identify effective treatments for acute heart failure in older patients. Trial Registration: ClinicalTrials.gov Identifier: NCT03683212.

Importance: The safety of the pulmonary embolism rule-out criteria (PERC), an 8-item block of clinical criteria aimed at ruling out pulmonary embolism (PE), has not been assessed in a randomized clinical trial. Objective: To prospectively validate the safety of a PERC-based strategy to rule out PE. Design, Setting, and Patients: A crossover cluster-randomized clinical noninferiority trial in 14 emergency departments in France. Patients with a low gestalt clinical probability of PE were included from August 2015 to September 2016, and followed up until December 2016. Interventions: Each center was randomized for the sequence of intervention periods. In the PERC period, the diagnosis of PE was excluded with no further testing if all 8 items of the PERC rule were negative. Main Outcomes and Measures: The primary end point was the occurrence of a thromboembolic event during the 3-month follow-up period that was not initially diagnosed. The noninferiority margin was set at 1.5%. Secondary end points included the rate of computed tomographic pulmonary angiography (CTPA), median length of stay in the emergency department, and rate of hospital admission. Results: Among 1916 patients who were cluster-randomized (mean age 44 years, 980 [51%] women), 962 were assigned to the PERC group and 954 were assigned to the control group. A total of 1749 patients completed the trial. A PE was diagnosed at initial presentation in 26 patients in the control group (2.7%) vs 14 (1.5%) in the PERC group (difference, 1.3% [95% CI, -0.1% to 2.7%]; P = .052). One PE (0.1%) was diagnosed during follow-up in the PERC group vs none in the control group (difference, 0.1% [95% CI, -∞ to 0.8%]). The proportion of patients undergoing CTPA in the PERC group vs control group was 13% vs 23% (difference, -10% [95% CI, -13% to -6%]; P < .001). In the PERC group, rates were significantly reduced for the median length of emergency department stay (mean reduction, 36 minutes [95% CI, 4 to 68]) and hospital admission (difference, 3.3% [95% CI, 0.1% to 6.6%]). Conclusions and Relevance: Among very low-risk patients with suspected PE, randomization to a PERC strategy vs conventional strategy did not result in an inferior rate of thromboembolic events over 3 months. These findings support the safety of PERC for very low-risk patients presenting to the emergency department. Trial Registration: clinicaltrials.gov Identifier: NCT02375919.

Importance: An international task force recently redefined the concept of sepsis. This task force recommended the use of the quick Sequential Organ Failure Assessment (qSOFA) score instead of systemic inflammatory response syndrome (SIRS) criteria to identify patients at high risk of mortality. However, these new criteria have not been prospectively validated in some settings, and their added value in the emergency department remains unknown. Objective: To prospectively validate qSOFA as a mortality predictor and compare the performances of the new sepsis criteria to the previous ones. Design, Settings, and Participants: International prospective cohort study, conducted in France, Spain, Belgium, and Switzerland between May and June 2016. In the 30 participating emergency departments, for a 4-week period, consecutive patients who visited the emergency departments with suspected infection were included. All variables from previous and new definitions of sepsis were collected. Patients were followed up until hospital discharge or death. Exposures: Measurement of qSOFA, SOFA, and SIRS. Main Outcomes and Measures: In-hospital mortality. Results: Of 1088 patients screened, 879 were included in the analysis. Median age was 67 years (interquartile range, 47-81 years), 414 (47%) were women, and 379 (43%) had respiratory tract infection. Overall in-hospital mortality was 8%: 3% for patients with a qSOFA score lower than 2 vs 24% for those with qSOFA score of 2 or higher (absolute difference, 21%; 95% CI, 15%-26%). The qSOFA performed better than both SIRS and severe sepsis in predicting in-hospital mortality, with an area under the receiver operating curve (AUROC) of 0.80 (95% CI, 0.74-0.85) vs 0.65 (95% CI, 0.59-0.70) for both SIRS and severe sepsis (P < .001; incremental AUROC, 0.15; 95% CI, 0.09-0.22). The hazard ratio of qSOFA score for death was 6.2 (95% CI, 3.8-10.3) vs 3.5 (95% CI, 2.2-5.5) for severe sepsis. Conclusions and Relevance: Among patients presenting to the emergency department with suspected infection, the use of qSOFA resulted in greater prognostic accuracy for in-hospital mortality than did either SIRS or severe sepsis. These findings provide support for the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) criteria in the emergency department setting. Trial Registration: clinicaltrials.gov Identifier: NCT02738164.

BACKGROUND: It has been reported that emergency department length of stay (ED-LOS) for older patients is longer than average. Our objective was to determine the effect of age, patient's clinical acuity and complexity, and care pathways on ED-LOS and ED plus observation unit (EDOU) LOS (EDOU-LOS). METHODS: This was a prospective, multicentre, observational study including all patients attending in 2011. Age groups were: I, <50; II, ≥50-64; III, ≥65-74; IV, ≥75-84; V, ≥85â years. Univariate and multivariate analyses were performed. RESULTS: Of 125â 478 attendances, 20â 845(16.6%) were of patients aged ≥65â years. Multivariate analysis found significant predictors for ED-LOS (C-statistics 0.79, p<0.0000001) to be: arrival mode (ambulance, OR 1.13 (95% CI 1.08 to 1.18)); acuity level (level 4, OR 1.24 (95% CI 1.21 to 1.28); level 1-3, OR 1.54 (95% CI 1.5 to 1.59)); haematological examinations (OR 3.34 (95% CI 3.15 to 3.56)); intravenous treatment (OR 1.58 (95% CI 1.47 to 1.69)); monitoring of vital signs (OR 1.89 (95% CI 1.69 to 2.10)); x-ray examinations (OR 1.53 (95% CI 1.45 to 1.61)); CT/MRI/ultrasound (OR 2.60 (95% CI 2.39 to 2.82)); and specialist advice (OR 1.39 (95% CI 1.30 to 1.48)). For EDOU-LOS (C-statistics 0.81, p<0.0000001) we found: age group (II, OR 1.19 (95% CI 1.16 to 1.22); III, OR 1.42 (95% CI 1.38 to 1.46); IV, OR 1.69 (95% CI 1.65 to 1.74); V, 2.01 (95% CI 1.96 to 2.07)); acuity level (level 4, OR 1.31 (95% CI 1.27 to 1.35); level 1-3, OR 1.71 (95% CI 1.66 to 1.77)); haematological examinations (OR 7.81 (95% CI 7.23 to 8.43)); intravenous treatment (OR 1.95 (95% CI 1.8 to 2.12)); x-ray examinations (OR 1.95 (95% CI 1.85 to 2.06)); CT/MRI/ultrasound (OR 6.74 (95% CI 5.98 to 7.6)); specialist advice (OR 2.24 (95% CI 2.07 to 2.42)); admission to a medical or surgical ward (OR 0.61 (95% CI 0.54 to 0.68)); and transfer (OR 1.79 (95% CI 1.54 to 2.07)). CONCLUSIONS: Whereas ED-LOS and EDOU-LOS seem to be directly related to patients' acuity and complexity, notably the need for diagnostic and therapeutic interventions, only EDOU-LOS was significantly associated with age and proposed care pathways. We propose that EDOU-LOS measurement should be made in EDs with an OU.

To estimate the rate of inappropriate diagnosis in patients who visited the ED with thrombotic microangiopathy (TMA) and to assess the factors and outcomes associated with emergency department (ED) misdiagnosis. Retrospective multicenter study of adult patients admitted to the intensive care unit (ICU) for TMA from 2012 to 2021 who had previously attended the ED for a reason related to TMA. Patient characteristics and outcomes were compared in a univariate analysis based on whether a TMA diagnosis was mentioned in the ED or not. Forty patients were included. The diagnosis of TMA was not mentioned in the ED in 16 patients (40%). Patients for whom the diagnosis was mentioned in the ED had more frequently a request for schistocytes research, and therefore had more often objectified schistocytes. They also had more frequently a troponin dosage in the ED (even if the difference was not significant), an ECG performed or interpreted, and were admitted more quickly in the ICU (0 [0-0] vs 2 [0-2] days; P = 0.002). Hemoglobin levels decreased significantly in both groups, and creatinine levels increased significantly in the misdiagnosis group between ED arrival and ICU admission. In patients with a final diagnosis of TTP, the time to platelets durable recovery was shorter for those in whom the diagnosis was mentioned in the ED without reaching statistical significance (7 [5-11] vs 14 [5-21] days; P = 0.3).

The transmission risk of SARS-CoV-2 within hospitals can exceed that in the general community because of more frequent close proximity interactions (CPIs). However, epidemic risk across wards is still poorly described. We measured CPIs directly using wearable sensors given to all present in a clinical ward over a 36-h period, across 15 wards in three hospitals in April-June 2020. Data were collected from 2114 participants and combined with a simple transmission model describing the arrival of a single index case to the ward to estimate the risk of an outbreak. Estimated epidemic risk ranged four-fold, from 0.12 secondary infections per day in an adult emergency to 0.49 per day in general paediatrics. The risk presented by an index case in a patient varied 20-fold across wards. Using simulation, we assessed the potential impact on outbreak risk of targeting the most connected individuals for prevention. We found that targeting those with the highest cumulative contact hours was most impactful (20% reduction for 5% of the population targeted), and on average resources were better spent targeting patients. This study reveals patterns of interactions between individuals in hospital during a pandemic and opens new routes for research into airborne nosocomial risk.

We present the case of an 81-year-old man, who was immunocompetent, who was admitted to the hospital with symptoms of fever and dyspnea suspected to be caused by COVID-19. Further examination revealed a triple coinfection, as determined by multiplex polymerase chain reaction testing, caused by the respiratory syncytial virus, human coronavirus OC43, and rhinovirus. Upon auscultation, diffuse wheezing without crackles was detected. After ruling out the possibility of acute heart failure with pulmonary edema, the patient was treated with nebulization of terbutaline for a period of 72 hours. This case serves to demonstrate the potential dangers of lifting barrier measures, such as mandatory face masks in high-risk areas, during the fall-winter season. In addition, it highlights the challenges that may arise in the post-COVID-19 era because reliance on flu vaccinations alone may not be sufficient.

INTRODUCTION: Prior to the emergence of COVID-19, when influenza was the predominant cause of viral respiratory tract infections (VRTIs), this study aimed to analyze the distinct biological abnormalities associated with influenza in outpatient settings. METHODS: A multicenter retrospective study was conducted among outpatients, with the majority seeking consultation at the emergency department, who tested positive for VRTIs using RT-PCR between 2016 and 2018. Patient characteristics were compared between influenza (A and B types) and non-influenza viruses, and predictors of influenza were identified using two different models focusing on absolute eosinopenia (0/mm3) and lymphocyte count <800/mm3. RESULTS: Among 590 VRTIs, 116 (19.7%) were identified as outpatients, including 88 cases of influenza. Multivariable logistic regression analysis revealed the following predictors of influenza: in the first model, winter season (adjusted odds ratio [aOR] 7.1, 95% confidence interval [CI] 1.12-45.08) and absolute eosinopenia (aOR 6.16, 95% CI 1.14-33.24); in the second model, winter season (aOR 9.08, 95% CI 1.49-55.40) and lymphocyte count <800/mm3 (aOR 7.37, 95% CI 1.86-29.20). Absolute eosinopenia exhibited the highest specificity and positive predictive value (92% and 92.3%, respectively). CONCLUSION: During the winter season, specific biological abnormalities can aid physicians in identifying influenza cases and guide the appropriate use of antiviral therapy when rapid molecular tests are not readily available.
RESUMO
OBJECTIVES: Respiratory syncytial virus (RSV) is a common agent of viral respiratory infections with significant morbidity and mortality in adults. The objective of this study was to determine risk factors for mortality and invasive mechanical ventilation and to describe the characteristics of patients who received ribavirin. METHODS: A retrospective multicentre observational cohort study was conducted in Great Paris area hospitals, including patients hospitalised between 1 January 2015 and 31 December 2019 for documented RSV infection. Data were extracted from the Assistance Publique-Hôpitaux de Paris Health Data Warehouse. The primary endpoint was in-hospital mortality. RESULTS: One thousand one hundred sixty-eight patients were hospitalised for RSV infection, including 288 (24.6%) patients who required intensive care unit (ICU) admission. The median (interquartile range) age of patients was 75 (63-85) years, and 54% (n = 631/1168) of them were women. In-hospital mortality was 6.6% (n = 77/1168) in the whole cohort and 12.8% (n = 37/288) in ICU patients. Factors associated with hospital mortality were age >85 years (adjusted odds ratio [aOR] = 6.29, 95% confidence interval [2.47-15.98]), acute respiratory failure (aOR = 2.83 [1.19-6.72]), non-invasive (aOR = 12.60 [1.41-112.36]), and invasive mechanical ventilation support (aOR = 30.13 [3.17-286.27]) and neutropenia (aOR = 13.19 [3.27-53.27]). Factors associated with invasive mechanical ventilation were chronic heart (aOR = 1.98 [1.20-3.26]) or respiratory failure (aOR = 2.83 [1.67-4.80]), and co-infection (aOR = 2.62 [1.60-4.30]). Patients who were treated with ribavirin were significantly younger than others (62 [55-69] vs. 75 [63-86] years; p < 0.001), more frequently males (n = 34/48 [70.8%] vs. n = 503/1120 [44.9%]; p 0.001), and almost exclusively immunocompromised (n = 46/48 [95.8%] vs. n = 299/1120 [26.7%]; p < 0.001). DISCUSSION: The mortality rate of patients hospitalised with RSV infections was 6.6%. Twenty-five per cent of the patients required ICU admission.

BACKGROUND: Following a study of predictors of superinfection in viral respiratory tract infections (VRTIs), this study analyzes the predictors of the outcome. METHODS: Multicenter retrospective study conducted among adults who tested positive for VRTIs with reverse-transcription polymerase chain reaction. We compared characteristics between influenza virus, Paramyxoviridae, and Pneumoviridae and identified predictors of favorable short-term outcome, admission to the intensive care unit (ICU), and mortality. RESULTS: A total of 590 patients had VRTI, including 347 (59%) influenza infections. Mean (SD) patient age was 71.0 (18.3) years, with a sex ratio of 0.91. In multivariate analyses, predictors of favorable short-term outcome were age ≤75 years (adjusted odds ratio [aOR] 5.38 [95% confidence interval, 1.59-18.2]), absence of respiratory disease (4.94 [1.01-24.37]), and absence of superinfection (aOR 3.91 [1.37-11.13]). The predictors of ICU admission were age ≤75 years (aOR 3.28 [1.71-6.25]), chronic respiratory disease (aOR 2.49 [1.20-5.19]), and procalcitonin level >0.25 ng/mL (aOR 4.25 [1.55-11.67]). Predictors of mortality were use of inhaled corticosteroids (2.49 [1.10-5.63]), influenza infection (2.73 [1.27-5.85]), Charlson score ≥5 (5.35 [1.90-15.05]), superinfection (2.54 [1.05-6.18]), and eosinophil count <50/µL (4.39 [1.19-16.2]). Certainty of superinfection was significantly associated with mortality (2.23 [1.15-4.3]). CONCLUSION: Our study revealed that superinfection was significantly related to the outcome, and that virus species affects mortality. These findings emphasize the need for improving the tools used in daily practice to confirm certainty of superinfection and for broader implementation of vaccination of individuals at risk of VRTIs.

Background: COVID-19 is a major pandemic with potential cardiovascular complications. Few studies have focused on electrocardiogram (ECG) modifications in COVID-19 patients. Method and results: We reviewed from our database all patients referred to our hospital for COVID-19 between January 1st, 2020, and December 31st, 2020: 669 patients were included and 98 patients died from COVID-19 (14.6%). We systematically analyzed ECG at admission and during hospitalization if available. ECG was abnormal at admission in 478 patients (71.4%) and was more frequently abnormal in patients who did not survive (88.8 vs. 68.5%, p < 0.001). The most common ECG abnormalities associated with death were left anterior fascicular block (39.8 vs. 20.0% among alive patients, p < 0.001), left and right bundle branch blocks (p = 0.002 and p = 0.02, respectively), S1Q3 pattern (14.3 vs. 6.0%, p = 0.006). In multivariate analysis, at admission, the presence of left bundle branch block remained statistically related to death [OR = 3.82, 95% confidence interval (CI): 1.52-9.28, p < 0.01], as well as S1Q3 pattern (OR = 3.17, 95% CI: 1.38-7.03, p < 0.01) and repolarization abnormalities (OR = 2.41, 95% CI: 1.40-4.14, p < 0.01).On ECG performed during hospitalization, the occurrence of new repolarization abnormality was significantly related to death (OR = 2.72, 95% CI: 1.14-6.54, p = 0.02), as well as a new S1Q3 pattern (OR = 13.23, 95% CI: 1.49-286.56, p = 0.03) and new supraventricular arrhythmia (OR = 3.8, 95% CI: 1.11-13.35, p = 0.03). Conclusion: The presence of abnormal ECG during COVID-19 is frequent. Physicians should be aware of the usefulness of ECG for risk stratification during COVID-19.
