Epidemiology of invasive aspergillosis in critically ill patients : clinical presentation, underlying conditions, and outcome

Introduction: Invasive aspergillosis (IA) is a fungal infection that particularly affects immunocompromised hosts. Recently, several studies have indicated a high incidence of IA in intensive care unit (ICU) patients. However, few data are available on the epidemiology and outcome of patients with IA in this setting. Methods: An observational study including all patients with a positive Aspergillus culture during ICU stay was performed in 30 ICUs in 8 countries. Cases were classified as proven IA, putative IA or Aspergillus colonization according to recently validated criteria. Demographic, microbiologic and diagnostic data were collected. Outcome was recorded 12 weeks after Aspergillus isolation. Results: A total of 563 patients were included, of whom 266 were colonized (47%), 203 had putative IA (36%) and 94 had proven IA (17%). The lung was the most frequent site of infection (94%), and Aspergillus fumigatus the most commonly isolated species (92%). Patients with IA had higher incidences of cancer and organ transplantation than those with colonization. Compared with other patients, they were more frequently diagnosed with sepsis on ICU admission and more frequently received vasopressors and renal replacement therapy (RRT) during the ICU stay. Mortality was 38% among colonized patients, 67% in those with putative IA and 79% in those with proven IA (P < 0.001). Independent risk factors for death among patients with IA included older age, history of bone marrow transplantation, and mechanical ventilation, RRT and higher Sequential Organ Failure Assessment score at diagnosis. Conclusions: IA among critically ill patients is associated with high mortality. Patients diagnosed with proven or putative IA had greater severity of illness and more frequently needed organ support than those with Aspergillus spp colonization

Extracorporeal Membrane Oxygenation for Severe Acute Respiratory Distress Syndrome associated with COVID-19: An Emulated Target Trial Analysis.

RATIONALE: Whether COVID patients may benefit from extracorporeal membrane oxygenation (ECMO) compared with conventional invasive mechanical ventilation (IMV) remains unknown. OBJECTIVES: To estimate the effect of ECMO on 90-Day mortality vs IMV only Methods: Among 4,244 critically ill adult patients with COVID-19 included in a multicenter cohort study, we emulated a target trial comparing the treatment strategies of initiating ECMO vs. no ECMO within 7 days of IMV in patients with severe acute respiratory distress syndrome (PaO2/FiO2 <80 or PaCO2 ≥60 mmHg). We controlled for confounding using a multivariable Cox model based on predefined variables. MAIN RESULTS: 1,235 patients met the full eligibility criteria for the emulated trial, among whom 164 patients initiated ECMO. The ECMO strategy had a higher survival probability at Day-7 from the onset of eligibility criteria (87% vs 83%, risk difference: 4%, 95% CI 0;9%) which decreased during follow-up (survival at Day-90: 63% vs 65%, risk difference: -2%, 95% CI -10;5%). However, ECMO was associated with higher survival when performed in high-volume ECMO centers or in regions where a specific ECMO network organization was set up to handle high demand, and when initiated within the first 4 days of MV and in profoundly hypoxemic patients. CONCLUSIONS: In an emulated trial based on a nationwide COVID-19 cohort, we found differential survival over time of an ECMO compared with a no-ECMO strategy. However, ECMO was consistently associated with better outcomes when performed in high-volume centers and in regions with ECMO capacities specifically organized to handle high demand.

Ten golden rules for optimal antibiotic use in hospital settings: the WARNING call to action

Antibiotics are recognized widely for their benefits when used appropriately. However, they are often used inappropriately despite the importance of responsible use within good clinical practice. Effective antibiotic treatment is an essential component of universal healthcare, and it is a global responsibility to ensure appropriate use. Currently, pharmaceutical companies have little incentive to develop new antibiotics due to scientific, regulatory, and financial barriers, further emphasizing the importance of appropriate antibiotic use. To address this issue, the Global Alliance for Infections in Surgery established an international multidisciplinary task force of 295 experts from 115 countries with different backgrounds. The task force developed a position statement called WARNING (Worldwide Antimicrobial Resistance National/International Network Group) aimed at raising awareness of antimicrobial resistance and improving antibiotic prescribing practices worldwide. The statement outlined is 10 axioms, or “golden rules,” for the appropriate use of antibiotics that all healthcare workers should consistently adhere in clinical practice

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P &lt; 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Analyse rétrospective de 24 patientes traitées pour une méningite carcinomateuse compliquant un cancer du sein

Introduction La méningite carcinomateuse survient chez environ 1 à 2% des cancers du sein métastatiques. Cette atteinte est caractérisée par un pronostic particulièrement sombre de quelques semaines. Il n'existe à ce jour aucun traitement validé des méningites carcinomateuses compliquant un cancer du sein. Les prises en charge proposées comportent habituellement la réalisation d'une chimiothérapie et d'une radiothérapie, dans un contexte d'emblée palliatif. En raison de l'existence de la barrière hémato-encéphalique, qui limite l'accessibilité des molécules utilisées par voie veineuse, la chimiothérapie employée est fréquemment du méthotrexate intrathécal administré par ponction lombaire ou via un réservoir externe. Le but de ce travail a été d'analyser de façon rétrospective les résultats d'un protocole utilisant du méthotrexate à haute dose par voie intrathécale chez des patientes présentant une méningite carcinomateuse compliquant un cancer du sein. Patientes et méthodes Toutes les patientes traitées au Centre Henri Becquerel pour une méningite carcinomateuse d'origine mammaire entre Juin 1999 et Mai 2008 et ayant reçu au moins un cycle de méthotrexate intrathécal haute dose (15 mg par jour de Jl à J5 puis reprise à J14) ont été incluses rétrospectivement. L'analyse a porté sur l'évolution clinique, la survie globale, les données du LCR et la toxicité du traitement. Résultats : Les données concernant 24 patientes, dont l'âge moyen était de 49 ans, ont été analysées. Les patientes ont reçu un nombre médian de cures de chimiothérapie intrathécale de 4. Toutes les patientes sauf une ont présenté une stabilisation ou une amélioration des symptômes liés à la méningite carcinomateuse, et pour neuf patientes (38%) tous les symptômes liés à la méningite carcinomateuse ont complètement disparus. La régression complète des symptômes initiaux de la méningite et la négativation de la cytologie du LCR étaient les deux seuls facteurs pronostiques ou prédictifs pour la survie dans cette série. Onze patientes (46%) ont présenté une négativation de la cytologie du LCR en cours de traitement. Chez ces patientes, une réponse clinique était plus fréquemment observée (p=0,02) que chez les patientes conservant une cytologie du LCR positive pendant le traitement. Pour l'ensemble des patientes, la survie globale moyenne était de 175 jours, avec une médiane de 150 jours. Cette survie médiane était significativement plus longue dans le groupe des malades ayant une négativation de la cytologie du LCR (217 jours contre 102, p=0,005), et en cas de disparition de la totalité des symptômes liés à la méningite carcinomateuse (223 jours contre 140, p=0,04). Les courbes de survie confirment la valeur prédictive de la réponse cytologique (p=0,0016) et de la disparition des symptômes liés à la méningite carcinomateuse (p=0,047). Un état général altéré au moment du diagnostic de la méningite carcinomateuse ne constituait pas un facteur péjoratif de survie dans cette étude. La tolérance globale était bonne. Conclusion Cette étude rétrospective suggère un possible bénéfice du traitement par méthotrexate intrathécal à haute dose des méningites carcinomateuse d'origine mammaire. L'évolution clinique et cytologique en cours de traitement pourrait aider à décider de la poursuite ou de l'interruption du traitement intrathécal.ROUEN-BU Médecine-Pharmacie (765402102) / SudocSudocFranceF
