RESUMEN
In September 2023, a botulism outbreak affecting 15 individuals occurred in Bordeaux, France, during the Rugby World Cup. We report on eight individuals from four different countries on two continents admitted to the intensive care unit at our hospital, where six required invasive mechanical ventilation. Cases reported consuming locally produced canned sardines at a restaurant. This report highlights the importance of rapid, worldwide alerts from health authorities to prevent severe consequences of such outbreaks, particularly during events attracting international visitors.

This study aims to assess the efficacy and safety of convalescent plasma therapy (CPT) in COVID-19 critically ill patients with protracted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNAemia. A retrospective cohort study was conducted in intensive care unit (ICU). All patients with severe COVID-19 pneumonia for whom RNAemia remained positive more than 14 days after onset of the infection were included and given CPT. The primary objective was to evaluate SARS-CoV-2 RNAemia 7 days (D7) after CPT. A total of 14 patients were included and they received a median CPT volume of 828 ml (range: 817-960). CPT was administered in a median time of 14 days after ICU admission. At D7, 13/14 patients had negative SARS-CoV-2 blood PCR and one patient had negative blood PCR 11 days after CPT. At D7 and at D14, the clinical status was improved in 7/14 and 11/14 patients, respectively. The 28-day mortality rate was 14%. No CPT-related adverse effects had been reported. CPT is safe and may be efficient in patients with protracted RNAemia admitted in ICU for severe COVID-19 pneumonia. Randomized controlled trials are needed to confirm these results.

OBJECTIVES: In the last decades, the number of cancer patients admitted in intensive care units (ICUs) for septic shock has dramatically increased. However, prognosis data remain scarce. METHODS: To assess the 180-day mortality rate in cancer patients admitted to the ICU for septic shock, a 5-year prospective study was performed. All adult patients admitted for septic shock were included and categorized into the following two groups and four subgroups: cancer patients (solid tumor or hematological malignancy) and non-cancer patients (immunocompromised or not). Data were collected and compared between the groups. Upon early ICU admission, the decision to forgo life-sustaining therapy (DFLST) or not was made by consultation among hematologists, oncologists, and the patients or their relatives. RESULTS: During the study period, 496 patients were admitted for septic shock: 252 cancer patients (119 hematological malignancies and 133 solid tumors) and 244 non-cancer patients. A DFLST was made for 39% of the non-cancer patients and 52% of the cancer patients. The 180-day mortality rate among the cancer patients was 51% and 68% for those with hematological malignancies and solid cancers, respectively. The mortality rate among the non-cancer patients was 44%. In a multivariate analysis, the performance status, Charlson comorbidity index, simplified acute physiology score 2, sequential organ failure assessment score, and DFLST were independent predictors of 180-day mortality. CONCLUSIONS: Despite early admission to the ICU, the 180-day mortality rate due to septic shock was higher in cancer patients compared with non-cancer patients, due to excess mortality in the patients with solid tumors. The long-term prognosis of cancer patients with septic shock is modulated by their general state, severity of organ failure, and DFLST.

Little data is available on extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-E) rectal colonization in cancer patients admitted to the intensive care unit (ICU). We aimed to describe the epidemiology of ESBL-E in cancer patients hospitalized in the ICU compared with non-cancer patients. ESBL-E colonization was detected in 6.6% of 1,013 cancer patients and 6.4% of 1625 non-cancer patients. At admission, among the 172 colonized patients: 48/67 cancer patients and 78/105 non-cancer patients developed an infection, documented with an ESBL-E for 21% and 24% of them, respectively. The in-hospital mortality rate among colonized patients was 33% in cancer patients and 12% in non-cancer patients. In cancer patients, ESBL-E infections are rare but systematic rectal screening identifies high-risk population and guides empirical antibiotic therapy. It also contributes to being aware of the ICU microbiological ecology.

BACKGROUND: Dexamethasone and tocilizumab are used to treat severely ill COVID-19 patients admitted to intensive care units (ICUs). We explored whether combination therapy increased the risk of superinfection compared to dexamethasone alone. METHODS: This observational, retrospective study included critically ill COVID-19 adult patients admitted to our ICU because of respiratory failure. Patients received dexamethasone with (Group 1) or without (Group 2) tocilizumab. Data were collected from electronic medical files. RESULTS: A total of 246 patients were included, of whom 150 received dexamethasone and tocilizumab, while 96 received dexamethasone alone. Acute respiratory distress syndrome was evident on admission in 226 patients, 56 of whom required mechanical ventilation (MV). Superinfections, mainly respiratory, were diagnosed in 59 patients, including 34/150 (23%) in Group 1 and 25/96 (26%) in Group 2 (p = 0.32). After multivariate analysis, the factors associated with a higher risk of superinfection included hematological malignancy (hazard ratio (HR): 2.47 (1.11-5.47), p = 0.03), MV (HR: 3.74 (1.92-7.26), p = 0.0001), and a higher SAPS-II score on admission (HR: 1.03 (1.01-1.06), p = 0.006). CONCLUSION: In critically ill COVID-19 patients, the addition of tocilizumab to dexamethasone was not associated with an increased risk of superinfection.
RESUMEN
PURPOSE: This retrospective study was performed in order to determine if patients with very severe chronic obstructive pulmonary disease (COPD) have larger main bronchi than patients with less severe disease. METHODS: Charts of patients having had a spirometric evaluation of their COPD and a digitized thin-slice computed tomography (CT) scan between January 2004 and September 2007 were reviewed. Adequate CT scans of male patients [i.e., those allowing a multiplane reconstruction (MPR) of the upper tracheobronchial tree using a double orthogonal oblique method] were divided into two groups: group 1 [forced expiratory volume in 1 s (FEV(1)) ranging from 30% to 80%] and group 2 (FEV(1) < 30%). RESULTS: Intraobserver and interobserver coefficients of repeatability were 1.79 and 2.51 mm, respectively. Median values and interquartile ranges of minimum right main bronchial diameter were 11.0 (9.6-12.7) mm versus 12.7 (10.8-13.9) mm in groups 1 (27 patients) and 2 (10 patients), respectively (P = 0.048); values for the minimum left main bronchial diameter were 10.7 (8.9-11.9) mm versus 11.8 (11.2-12.4) mm in groups 1 and 2, respectively (P = 0.040). The difference between the groups in median values of the minimum right and left main bronchial diameters was 1.2 mm. Other values were similar in both groups. CONCLUSION: The difference in minimum main bronchial diameters between our two groups corresponded to a difference of two or three sizes of a double-lumen tube. This difference must be taken into account for tube selection for such patients. Further studies are needed to prove that CT scan MPR can improve patients' intraoperative care.

BACKGROUND: Patients presenting with acute myeloid leukemia (AML) at diagnosis are at high risk of severe complications and death, particularly with high white blood cell (WBC) count. In this retrospective study, we evaluate interest of early and systematic support in the intensive care unit (ICU) for AML with hyperleukocytosis (AML-HL) at diagnosis. METHODS: Patients with AML-HL, defined by WBC > 50 × 109/L, primary referred in ICU ("Early ICU") without organ failure and before initiating chemotherapy induction were compared to patients first admitted in the Hematology Department who required a secondary transfer in ICU ("Late ICU") or not ("No ICU"). Primary end point was mortality during the first month, and secondary end points were the use of life-sustaining therapies in ICU and risk factors for ICU transfer and mortality. RESULTS: One hundred fifty-four patients were included: 77 (50%) to the group "No ICU", 18 (12%) to "Late ICU" and 59 (38%) to "Early ICU". Mortality at day 30 was higher in "Late ICU" than in "Early ICU" and "No ICU", with 27.8%; 16.9% and 2.6% respectively (P < 0.001). "Late ICU" patients had an increased use of life-sustaining therapy comparing to "Early ICU" patients (56% vs. 29%, P = 0.04). CONCLUSIONS: Early referral to ICU reduces morbidity and seems an effective strategy to reduce short-term mortality in AML-HL at diagnosis.
RESUMEN
BACKGROUND: Coronavirus disease 2019 (COVID-19)-associated acute kidney injury (AKI) frequency, severity and characterization in critically ill patients has not been reported. METHODS: Single-centre cohort performed from 3 March 2020 to 14 April 2020 in four intensive care units in Bordeaux University Hospital, France. All patients with COVID-19 and pulmonary severity criteria were included. AKI was defined using Kidney Disease: Improving Global Outcomes (KDIGO) criteria. A systematic urinary analysis was performed. The incidence, severity, clinical presentation, biological characterization (transient versus persistent AKI; proteinuria, haematuria and glycosuria) and short-term outcomes were evaluated. RESULTS: Seventy-one patients were included, with basal serum creatinine (SCr) of 69 ± 21 µmol/L. At admission, AKI was present in 8/71 (11%) patients. Median [interquartile range (IQR)] follow-up was 17 (12-23) days. AKI developed in a total of 57/71 (80%) patients, with 35% Stage 1, 35% Stage 2 and 30% Stage 3 AKI; 10/57 (18%) required renal replacement therapy (RRT). Transient AKI was present in only 4/55 (7%) patients and persistent AKI was observed in 51/55 (93%). Patients with persistent AKI developed a median (IQR) urine protein/creatinine of 82 (54-140) (mg/mmol) with an albuminuria/proteinuria ratio of 0.23 ± 20, indicating predominant tubulointerstitial injury. Only two (4%) patients had glycosuria. At Day 7 after onset of AKI, six (11%) patients remained dependent on RRT, nine (16%) had SCr >200 µmol/L and four (7%) had died. Day 7 and Day 14 renal recovery occurred in 28% and 52%, respectively. CONCLUSION: Severe COVID-19-associated AKI is frequent, persistent, severe and characterized by an almost exclusive tubulointerstitial injury without glycosuria.
