RESUMO
BACKGROUND: The prognosis of patients hospitalized with community-acquired pneumonia (CAP) with regards to intensive care unit (ICU) admission, short- and long-term mortality is correlated with patient's comorbidities. For patients hospitalized for CAP, including P-CAP, we assessed the prognostic impact of comorbidities known as at-risk (AR) or high-risk (HR) of pneumococcal CAP (P-CAP), and of the number of combined comorbidities. METHODS: Data on hospitalizations for CAP among the French 50+ population were extracted from the 2014 French Information Systems Medicalization Program (PMSI), an exhaustive national hospital discharge database maintained by the French Technical Agency of Information on Hospitalization (ATIH). Their admission diagnosis, comorbidities (nature, risk type and number), other characteristics, and their subsequent hospital stays within the year following their hospitalization for CAP were analyzed. Logistic regression models were used to assess the associations between ICU transfer, short- and 1-year in-hospital mortality and all covariates. RESULTS: From 182,858 patients, 149,555 patients aged ≥ 50 years (nonagenarians 17.8%) were hospitalized for CAP in 2014, including 8270 with P-CAP. Overall, 33.8% and 90.5% had ≥ 1 HR and ≥ 1 AR comorbidity, respectively. Cardiac diseases were the most frequent AR comorbidity (all CAP: 77.4%). Transfer in ICU occurred for 5.4% of CAP patients and 19.4% for P-CAP. Short-term and 1-year in-hospital mortality rates were 10.9% and 23% of CAP patients, respectively, significantly lower for P-CAP patients: 9.2% and 19.8% (HR 0.88 [95% CI 0.84-0.93], p < .0001). Both terms of mortality increased mostly with age, and with the number of comorbidities and combination of AR and HR comorbidities, in addition of specific comorbidities. CONCLUSIONS: Not only specific comorbidities, but also the number of combined comorbidities and the combination of AR and HR comorbidities may impact the outcome of hospitalized CAP and P-CAP patients.

We report a longitudinal analysis of the immune response associated with a fatal case of COVID-19 in Europe. This patient exhibited a rapid evolution towards multiorgan failure. SARS-CoV-2 was detected in multiple nasopharyngeal, blood, and pleural samples, despite antiviral and immunomodulator treatment. Clinical evolution in the blood was marked by an increase (2-3-fold) in differentiated effector T cells expressing exhaustion (PD-1) and senescence (CD57) markers, an expansion of antibody-secreting cells, a 15-fold increase in γδ T cell and proliferating NK-cell populations, and the total disappearance of monocytes, suggesting lung trafficking. In the serum, waves of a pro-inflammatory cytokine storm, Th1 and Th2 activation, and markers of T cell exhaustion, apoptosis, cell cytotoxicity, and endothelial activation were observed until the fatal outcome. This case underscores the need for well-designed studies to investigate complementary approaches to control viral replication, the source of the hyperinflammatory status, and immunomodulation to target the pathophysiological response. The investigation was conducted as part of an overall French clinical cohort assessing patients with COVID-19 and registered in clinicaltrials.gov under the following number: NCT04262921.

BACKGROUND: Care pathways and long-term outcomes of acute stroke patients requiring mechanical ventilation have not been thoroughly studied. METHODS AND RESULTS: Stroke Prognosis in Intensive Care (SPICE) is a prospective multicenter cohort study which will be conducted in 34 intensive care units (ICUs) in the Paris, France area. Patients will be eligible if they meet all of the following inclusion criteria: (1) age of 18 years or older; (2) acute stroke (i.e., ischemic stroke, intracranial hemorrhage, or subarachnoid hemorrhage) diagnosed on neuroimaging; (3) ICU admission within 7 days before or after stroke onset; and (4) need for mechanical ventilation for a duration of at least 24 h. Patients will be excluded if they meet any of the following: (1) stroke of traumatic origin; (2) refusal to participate; and (3) privation of liberty by administrative or judicial decision. The primary endpoint is poor functional outcome at 1 year, defined by a score of 4 to 6 on the modified Rankin scale (mRS), indicating severe disability or death. Main secondary endpoints will include decisions to withhold or withdraw care, mRS scores at 3 and 6 months, and health-related quality of life at 1 year. CONCLUSIONS: The SPICE multicenter study will investigate 1-year outcomes, ethical issues, as well as care pathways of acute stroke patients requiring invasive ventilation in the ICU. Gathered data will delineate human resources and facilities needs for adequate management. The identification of prognostic factors at the acute phase will help to identify patients who may benefit from prolonged intensive care and rehabilitation. TRIAL REGISTRATION: NCT03335995.

PURPOSES: Streptococcus pneumoniae is a leading pathogen of severe community, hospital or nursing facility infections. We sought to describe characteristics of invasive pneumococcal infection (IPI) and pneumonia (due to the high mortality of intensive care-associated pneumonia) and to report outcomes according to various types of comorbidity. METHODS: Multicenter observational cohort study on the prospective Outcomerea database, including adult patients, with a hospital stay < 48 h before ICU admission and a documented IPI within the first 72 h of ICU admission. Comorbid conditions were defined according to the Knaus and Charlson classification. RESULTS: Of the 20,235 patients, 5310 (26.4%) had an invasive infection, including 560/5,310 (10.6%) who had an IPI. The ICU 28-day mortality was 109/560 (19.8%). Four factors were independently associated with mortality: SOFA day 1-2: [hazard ratio (HR) 1.21; 95% confidence interval (95% CI) 1.15-1.27, p < 0.001]; maximum lactate level day 1-2: (HR 1.07, 95% CI 1.02-1.12, p = 0.006); diabetes mellitus: (HR 1.91, 95% CI 1.23-3.03, p = 0.006) and appropriate antibiotics (HR 0.28, 95% CI 0.15-0.50, p < 0.001). Comparable results were obtained when other comorbid conditions were forced into the model. Diabetes impact was more pronounced in case of micro- or macro-angiopathy (HR 4.17, 95%CI 1.68-10.54, p = 0.003), in patients ≥ 65 years old (HR 2.59, 95% CI 1.56-4.28, < 0.001) and in those with body mass index (BMI) < 25 kg/m2 (HR 2.11, 95% CI 1.10-4.06, p = 0.025). CONCLUSIONS: Diabetes mellitus was the only comorbid condition which independently influenced mortality in patients with IPI. Its impact was more pronounced in patients with complications, aged ≥ 65 years and with BMI < 25 kg/m2.

BACKGROUND: Millions of individuals with obstructive sleep apnoea (OSA) are treated by CPAP aimed at reducing blood pressure (BP) and thus cardiovascular risk. However, evidence is scarce concerning the impact of different CPAP modalities on BP evolution. METHODS: This double-blind, randomised clinical trial of parallel groups of patients with OSA indicated for CPAP treatment compared the efficacy of fixed-pressure CPAP (FP-CPAP) with auto-adjusting CPAP (AutoCPAP) in reducing BP. The primary endpoint was the change in office systolic BP after 4â months. Secondary endpoints included 24â h BP measurements. RESULTS: Patients (322) were randomised to FP-CPAP (n=161) or AutoCPAP (n=161). The mean apnoea+hypopnoea index (AHI) was 43/h (SD, 21); mean age was 57 (SD, 11), with 70% of males; mean body mass index was 31.3â kg/m(2) (SD, 6.6) and median device use was 5.1â h/night. In the intention-to-treat analysis, office systolic blood pressure decreased by 2.2â mmâ Hg (95% CI -5.8 to 1.4) and 0.4â mmâ Hg (-4.3 to 3.4) in the FP-CPAP and AutoCPAP group, respectively (group difference: -1.3â mmâ Hg (95% CI -4.1 to 1.5); p=0.37, adjusted for baseline BP values). 24â h diastolic BP (DBP) decreased by 1.7â mmâ Hg (95% CI -3.9 to 0.5) and 0.5â mmâ Hg (95% CI -2.3 to 1.3) in the FP-CPAP and AutoCPAP group, respectively (group difference: -1.4â mmâ Hg (95% CI -2.7 to -0.01); p=0.048, adjusted for baseline BP values). CONCLUSIONS: The result was negative regarding the primary outcome of office BP, while FP-CPAP was more effective in reducing 24â h DBP (a secondary outcome). TRIAL REGISTRATION NUMBER: NCT01090297.

The diagnosis and follow-up of candidemia still rely on blood cultures (BCs). In vitro studies show that antifungals can significantly modify the result of blood culture not containing adsorbing agents. We aimed to evaluate, under clinical conditions, the impact on BC yeast detection of systemic antifungal therapy (SAT). Patients (n = 125) experiencing candidemia at Grenoble University Hospital (France) were included in a 4-year retrospective study. The Plus Aerobic/F (Aerobic) and Plus Anaerobic/F (Anaerobic) bottles, which both contain adsorbing resins and the non-resin selective Mycosis IC/F (Mycosis) bottles, were compared using multivariate hierarchical models adjusted for clinical characteristics. The positivity rate (PR) is decreased in patients with SAT (p < 0.01), abdominal surgery (p = 0.01), and hemodialysis (p = 0.02). In all bottles, SAT reduces PR by a factor of 0.16 (95 % CI: [0.08; 0.32]) and increases the time to positivity (TTP) by a factor of 1.76 ([1.30; 2.40]; p < 0.01). In the presence of SAT, TTP is higher in non-resin bottles (Mycosis) than in resin bottles (RR = 1.76, [1.30; 2.40]); however, the TTP in nonresin and resin bottles remains comparable. Although discordant results are observed with and without SAT (37 and 58 % respectively), we showed that the presence of SAT decreases significantly the agreement rate by a factor of 0.29 (CI: [0.12; 0.68]). The combination of Anaerobic and Mycosis bottles allowed a 100 % positivity rate for C. glabrata. SAT significantly affects BC results. Because they provide additional and complementary results, this study supports the concomitant use of resin and selective bottles, especially in patients receiving SAT.

BACKGROUND AND PURPOSE: Our aim was to characterize the clinical profile, temporal changes and outcomes of patients with severe encephalitis. METHODS: A retrospective cohort study was conducted on adult patients with encephalitis admitted to the medical intensive care unit (ICU) of a university hospital over a 20-year period. Patients' characteristics and outcomes were compared between two 10-year periods: (i) 1991-2001 and (ii) 2002-2012. Multivariate logistic regression was used to analyze factors associated with a poor outcome, as defined by a modified Rankin scale (mRS) score of 4-6 (severe disability or death) 90 days after admission. RESULTS: A total of 279 patients were studied. Causes of encephalitis were infections (n = 149, 53%), immune-mediated causes (n = 41, 15%) and undetermined causes (n = 89, 32%). The distribution of causes differed significantly between the two periods, with an increase in the proportion of encephalitis recognized to be of immune-mediated causes. At day 90, 208 (75%) patients had an mRS = 0-3 and 71 (25%) had an mRS = 4-6. After adjustment for functional status before admission, the following parameters were independently associated with a poor outcome: coma [odds ratio (OR) 7.09, 95% confidence interval (95% CI) 3.06-17.03], aspiration pneumonia (OR 4.02, 95% CI 1.47-11.03), a lower body temperature (per 1 degree, OR 0.72, 95% CI 0.53-0.97), elevated cerebrospinal fluid protein levels (per 1 g/l, OR 1.55, 95% CI 1.17-2.11) and delayed ICU admission (per 1 day, OR 1.04, 95% CI 1.01-1.07). CONCLUSIONS: Indicators of outcome in adult patients with severe encephalitis reflect both the severity of illness and systemic complications. Our data suggest that patients with acute encephalitis may benefit from early ICU admission.

BACKGROUND: Detailed information about lung cancer patients requiring admission to intensive care units (ICUs) is mostly restricted to single-center studies. Our aim was to evaluate the clinical characteristics and outcomes of lung cancer patients admitted to ICUs. PATIENTS AND METHODS: Prospective multicenter study in 449 patients with lung cancer (small cell, n = 55; non-small cell, n = 394) admitted to 22 ICUs in six countries in Europe and South America during 2011. Multivariate Cox proportional hazards frailty models were built to identify characteristics associated with 30-day and 6-month mortality. RESULTS: Most of the patients (71%) had newly diagnosed cancer. Cancer-related complications occurred in 56% of patients; the most common was tumoral airway involvement (26%). Ventilatory support was required in 53% of patients. Overall hospital, 30-day, and 6-month mortality rates were 39%, 41%, and 55%, respectively. After adjustment for type of admission and early treatment-limitation decisions, determinants of mortality were organ dysfunction severity, poor performance status (PS), recurrent/progressive cancer, and cancer-related complications. Mortality rates were far lower in the patient subset with nonrecurrent/progressive cancer and a good PS, even those with sepsis, multiple organ dysfunctions, and need for ventilatory support. Mortality was also lower in high-volume centers. Poor PS predicted failure to receive the initially planned cancer treatment after hospital discharge. CONCLUSIONS: ICU admission was associated with meaningful survival in lung cancer patients with good PS and non-recurrent/progressive disease. Conversely, mortality rates were very high in patients not fit for anticancer treatment and poor PS. In this subgroup, palliative care may be the best option.

The incidence of adenocarcinoma is increasing, particularly among females. We sought to assess the role of tobacco consumption in clinical presentation according to sex. In this retrospective study, 848 patients diagnosed between 1997 and 2006 at Grenoble University Hospital (Grenoble, France) were stratified into four groups according to smoking habits. Differences between sexes and two contrasting female profiles emerged. Female current smokers were younger than female never-smokers (median 51 versus 69 yrs; p < 0.001), more often had surgery (62.7% versus 39%; p = 0.01) and had a median (95% CI) estimated survival of 26.2 (18.1-49.2) versus 15.1 (12.8-22.2) months (p = 0.002). Both groups had similar survival when taking treatment into account. Among males, smoking did not influence presentation. Male current smokers were older than female current smokers (median 59 yrs; p < 0.001) and fewer had surgery (48.8%; p = 0.015), although the percentage of stage IIIb-IV disease was similar (53% and 46%; nonsignificant) and they had a poorer estimated survival of 14.3 (13.0-18.5) months (p = 0.0024). Males smoked more than females (median 41 versus 30 pack-yrs; p < 0.001). Quitting smoking delayed age at diagnosis by 11 yrs for females (p = 0.0035) and 8 yrs for males (p < 0.001). Our results support the hypothesis that carcinogenesis differs between males and females, and between female smokers and never-smokers.

A survey was undertaken to evaluate the level of computerization in intensive care units (ICUs) within a French network dedicated to the surveillance of healthcare-associated infections, antimicrobial use (AMU) and antimicrobial resistance (AMR) in ICUs (REA-REZO). Ninety-eight ICUs responded, and patient records were computerized in 57%, antimicrobial prescriptions were computerized in 59% and AMR epidemiology was computerized in 72%. AMU and AMR feedback was provided to the ICU itself for 77% and 65% of ICUs, respectively, and feedback was provided to the national surveillance for 79% and 65% of ICUs, respectively. This study suggests that the level of computerization in ICUs requires further improvement.

The aim of the present study was to examine whether prone positioning (PP) affects ventilator associated-pneumonia (VAP) and mortality in patients with acute lung injury/adult respiratory distress syndrome. 2,409 prospectively included patients were admitted over 9 yrs (2000-2008) to 12 French intensive care units (ICUs) (OUTCOMEREA). The patients required invasive mechanical ventilation (MV) and had arterial oxygen tension/inspiratory oxygen fraction ratios <300 during the first 48 h. Controls were matched to PP patients on the PP propensity score (+/-10%), MV duration longer than that in PP patients before the first turn prone, and centre. VAP incidence was similar in the PP and control groups (24 versus 13 episodes.1,000 patient-days MV(-1) respectively, p = 0.14). After adjustment, PP did not decrease VAP occurrence (HR 1.64 (95% CI 0.70-3.84); p = 0.25) but significantly delayed hospital mortality (HR 0.56 (95% CI 0.39-0.79); p = 0.001), without decreasing 28-day mortality (37% in both groups). Post hoc analyses indicated that PP did not protect against VAP but, when used for >1 day, might decrease mortality and benefit the sickest patients (Simplified Acute Physiology Score >50). In ICU patients with hypoxaemic acute respiratory failure, PP had no effect on the risk of VAP. PP delayed mortality without decreasing 28-day mortality. PP >1 day might decrease mortality, particularly in the sickest patients.

We present the case of a 21-year-old man admitted to the intensive care unit with multi-organ failure due to multidrug-resistant tuberculosis (TB). TB treatment initially comprised moxifloxacin, ethambutol, linezolid and amikacin administered intravenously. Due to suspected moxifloxacin-induced liver injury, we stopped all fluoroquinolones and switched to bedaquiline (BDQ), which is only available in tablets for oral administration. Since our patient had to be fed through a nasogastric tube (NGT), BDQ was administered after being crushed and dissolved in water; drug pharmacokinetics were studied using repeated blood sampling. Therapeutic drug monitoring showed that BDQ was detectable in blood plasma with a trough concentration above the supposed efficacy threshold, suggesting that this molecule could be administered through NGT.

HIV infection has evolved into a chronic disease with comorbidities since the combination antiretroviral therapy era. Complications still occur and patients may need to be admitted to an intensive care unit. Acute respiratory failure is the first cause of these admissions, questioning the administration of solid oral dosage formulations. This issue is also observed in geriatric units where the prevalence of dysphagia is high and underestimated. The problem of antiretroviral administration is critical: altered solid oral dosage formulations and/or administration via enteral feeding tubes are sometimes the only option. The aim is to help manage antiretroviral treatment in unconscious or intubated patients and those with swallowing disorders who are hospitalized in intensive care units or geriatric units. This review provides information on the main antiretroviral regimens and on practical and legal aspects of manipulating solid oral dosage formulations and administration via enteral feeding tubes. Alternatives to the solid formulation are available for most of the 27 oral antiretrovirals available, or manufacturers provide recommendations for patients who are unable to swallow. Manipulation of solid oral dosage formulations such as crushing tablets or opening capsules and administration via feeding tubes are frequently reported but should be the last option for safety and liability issues. Before any off-label administration of a drug, physicians should consider alternatives to the solid oral dosage formulation and check whether the drug can be altered. Therapeutic monitoring is important in this particular setting as the pharmacokinetic profile of drugs is difficult to predict.

BACKGROUND: End-of-life (EOL) communication is crucial, particularly for cancer patients. While advanced care planning is still uncommon, we sought to investigate its impact on care intensity in case of organ failure in lung cancer patients. METHODS: We prospectively included consecutive lung cancer patients hospitalised at the Grenoble University Hospital, France, between January 1, 2014 and March 31, 2016. Patients could be admitted several times and benefited from advanced care planning based on three care intensities: intensive care, maximal medical care, and exclusive palliative care. Patients' wishes were addressed. RESULTS: Data of 739 hospitalisations concerning 482 patients were studied. During the three first admissions, 173 (25%) patients developed organ failure, with intensive care proposed to 56 (32%), maximal medical care to 104 (60%), and exclusive palliative care to 13 (8%). Median time to organ failure was 9 days [IQR 25%-75%: 3-13]. All patients benefited from care intensity that was either equal to or lower than the care proposed. Specific wishes were recorded for 158 (91%) patients, with a discussion about EOL conditions held in 116 (73%). CONCLUSIONS: In case of organ failure, advanced care planning helps provide reasonable care intensity. The role of the patient's wishes as to the proposed care must be further investigated. CLINICAL TRIAL REGISTRATION: The study was registered at www.ClinicalTrials.gov with the identifier NCT02852629.

BACKGROUND: Colonization pressure is a risk factor for intensive care unit (ICU)-acquired multi-drug-resistant organisms (MDROs). AIM: To measure the long-term respective impact of colonization pressure on ICU-acquired extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-PE) and meticillin-resistant Staphylococcus aureus (MRSA). METHODS: All patients admitted to two ICUs (medical and surgical) between January 1997 and December 2015 were included in this retrospective observational study. Rectal and nasal surveillance cultures were obtained at admission and weekly thereafter. Contact precautions were applied for colonized or infected patients. Colonization pressure was defined as the ratio of the number of MDRO-positive patient-days (PDs) of each MDRO to the total number of PDs. Single-level negative binomial regression models were used to evaluate the incidence of weekly MDRO acquisition. FINDINGS: Among the 23,423 patients included, 2327 (10.0%) and 1422 (6.1%) were colonized with ESBL-PE and MRSA, respectively, including 660 (2.8%) and 351 (1.5%) acquisitions. ESBL-PE acquisition increased from 0.51/1000 patient-exposed days (PEDs) in 1997 to 6.06/1000 PEDs in 2015 (P<0.001). In contrast, MRSA acquisition decreased steadily from 3.75 to 0.08/1000 PEDs (P<0.001). Controlling for period-level covariates, colonization pressure in the previous week was associated with MDRO acquisition for ESBL-PE (P<0.001 and P=0.04 for medical and surgical ICU, respectively), but not for MRSA (P=0.34 and P=0.37 for medical and surgical ICU, respectively). The increase in colonization pressure was significant above 100/1000 PDs for ESBL-PE. CONCLUSION: Colonization pressure contributed to the increasing incidence of ESBL-PE but not MRSA. This study suggests that preventive control measures should be customized to MDROs.

OBJECTIVES: The prevention of catheter-related bloodstream infection (CRBSI) has been an area of intense research, but the heterogeneity of endpoints used to define catheter infection makes the interpretation of randomized controlled trials (RCTs) problematic. The aim of this study was to determine the validity of different endpoints for central venous catheter infections. DATA SOURCES: (a) Individual-catheter data were collected from 9428 catheters from four large RCTs; (b) study-level data from 70 RCTs were identified with a systematic search. Eligible studies were RCTs published between January 1987 and October 2018 investigating various interventions to reduce infections from short-term central venous catheters or short-term dialysis catheters. For each RCT the prevalence rates of CRBSI, quantitative catheter tip colonization, catheter-associated infection (CAI) and central line-associated bloodstream infection (CLABSI) were extracted for each randomized study arm. METHODS: CRBSI was used as the gold-standard endpoint, for which colonization, CAI and CLABSI were evaluated as surrogate endpoints. Surrogate validity was assessed as (1) the individual partial coefficient of determination (individual-pR2) using individual catheter data; (2) the coefficient of determination (study-R2) from mixed-effect models regressing the therapeutic effect size of the surrogates on the effect size of CRBSI, using study-level data. RESULTS: Colonization showed poor agreement with CRBSI at the individual-patient level (pR2 = 0.33 95% CI 0.28-0.38) and poor capture at the study level (R2 = 0.42, 95% CI 0.21-0.58). CAI showed good agreement with CRBSI at the individual-patient level (pR2 = 0.80, 95% CI 0.76-0.83) and moderate capture at the study level (R2 = 0.71, 95% CI 0.51-0.85). CLABSI showed poor agreement with CRBSI at the individual patient level (pR2 = 0.34, 95% CI 0.23-0.46) and poor capture at the study level (R2 = 0.28, 95% CI 0.07-0.76). CONCLUSIONS: CAI is a moderate to good surrogate endpoint for CRBSI. Colonization and CLABSI do not reliably reflect treatment effects on CRBSI and are consequently more suitable for surveillance than for clinical effectiveness research.

BACKGROUND: Antimicrobial stewardship interventions and programmes aim to ensure effective treatment while minimizing antimicrobial-associated harms including resistance. Practice in this vital area is undermined by the poor quality of research addressing both what specific antimicrobial use interventions are effective and how antimicrobial use improvement strategies can be implemented into practice. In 2016 we established a working party to identify the key design features that limit translation of existing research into practice and then to make recommendations for how future studies in this field should be optimally designed. The first part of this work has been published as a systematic review. Here we present the working group's final recommendations. METHODS: An international working group for design of antimicrobial stewardship intervention evaluations was convened in response to the fourth call for leading expert network proposals by the Joint Programming Initiative on Antimicrobial Resistance (JPIAMR). The group comprised clinical and academic specialists in antimicrobial stewardship and clinical trial design from six European countries. Group members completed a structured questionnaire to establish the scope of work and key issues to develop ahead of a first face-to-face meeting that (a) identified the need for a comprehensive systematic review of study designs in the literature and (b) prioritized key areas where research design considerations restrict translation of findings into practice. The working group's initial outputs were reviewed by independent advisors and additional expertise was sought in specific clinical areas. At a second face-to-face meeting the working group developed a theoretical framework and specific recommendations to support optimal study design. These were finalized by the working group co-ordinators and agreed by all working group members. RESULTS: We propose a theoretical framework in which consideration of the intervention rationale the intervention setting, intervention features and the intervention aims inform selection and prioritization of outcome measures, whether the research sets out to determine superiority or non-inferiority of the intervention measured by its primary outcome(s), the most appropriate study design (e.g. experimental or quasi- experimental) and the detailed design features. We make 18 specific recommendation in three domains: outcomes, objectives and study design. CONCLUSIONS: Researchers, funders and practitioners will be able to draw on our recommendations to most efficiently evaluate antimicrobial stewardship interventions.

The European Early Lung Cancer (EUELC) project aims to determine if specific genetic alterations occurring in lung carcinogenesis are detectable in the respiratory epithelium. In order to pursue this objective, nonsmall cell lung cancer (NSCLC) patients with a very high risk of developing progressive lung cancer were recruited from 12 centres in eight European countries: France, Germany, southern Ireland, Italy, the Netherlands, Poland, Spain and the UK. In addition, NSCLC patients were followed up every 6 months for 36 months. A European Bronchial Tissue Bank was set up at the University of Liverpool (Liverpool, UK) to optimise the use of biological specimens. The molecular-pathological investigations were subdivided into specific work packages that were delivered by EUELC Partners. The work packages encompassed mutational analysis, genetic instability, methylation profiling, expression profiling utilising immunohistochemistry and chip-based technologies, as well as in-depth analysis of FHIT and RARbeta genes, the telomerase catalytic subunit hTERT and genotyping of susceptibility genes in specific pathways. The EUELC project engendered a tremendous collaborative effort, and it enabled the EUELC Partners to establish protocols for assessing molecular biomarkers in early lung cancer with the view to using such biomarkers for early diagnosis and as intermediate end-points in future chemopreventive programmes.

PURPOSE: We aimed to study the association of body temperature and other admission factors with outcomes of herpes simplex encephalitis (HSE) adult patients requiring ICU admission. METHODS: We conducted a retrospective multicenter study on patients diagnosed with HSE in 47 ICUs in France, between 2007 and 2017. Fever was defined as a body temperature higher or equal to 38.3 °C. Multivariate logistic regression analysis was used to identify factors associated with poor outcome at 90 days, defined by a score of 3-6 (indicating moderate-to-severe disability or death) on the modified Rankin scale. RESULTS: Overall, 259 patients with a score on the Glasgow coma scale of 9 (6-12) and a body temperature of 38.7 (38.1-39.2) °C at admission were studied. At 90 days, 185 (71%) patients had a poor outcome, including 44 (17%) deaths. After adjusting for age, fever (OR = 2.21; 95% CI 1.18-4.16), mechanical ventilation (OR = 2.21; 95% CI 1.21-4.03), and MRI brain lesions > 3 lobes (OR = 3.04; 95% CI 1.35-6.81) were independently associated with poor outcome. By contrast, a direct ICU admission, as compared to initial admission to the hospital wards (i.e., indirect ICU admission), was protective (OR = 0.52; 95% CI 0.28-0.95). Sensitivity analyses performed after adjustment for functional status before admission and reason for ICU admission yielded similar results. CONCLUSIONS: In HSE adult patients requiring ICU admission, several admission factors are associated with an increased risk of poor functional outcome. The identification of potentially modifiable factors, namely, elevated admission body temperature and indirect ICU admission, provides an opportunity for testing further intervention strategies.
