Efficacy of the my health too online cognitive behavioral therapy program for healthcare workers during the COVID-19 pandemic: A randomized controlled trial.

Background: Healthcare workers' mental health has been impacted by the COVID-19 pandemic, emphasizing the need for mental health interventions in this population. Online cognitive behavioral therapy (CBT) is efficient to reduce stress and may reach numerous professionals. We developed "MyHealthToo", an online CBT program to help reduce stress among healthcare workers during the COVID-19 pandemic. Objective: The aim of our study is to investigate the efficacy of an online CBT program on stress and mental health conditions among healthcare workers during a health crisis. Methods: We performed a multicentric randomized controlled trial among 155 participants allocated either to the experimental or active control group (bibliotherapy). The primary outcome was the decrease of perceived stress scores (PSS-10) post-treatment. Secondary outcomes included depression, insomnia and PTSD symptoms along with self-reported resilience and ruminations. Assessments were scheduled pretreatment, mid-treatment (4 weeks), post-treatment (8 weeks), and at 1-month and 4-months follow-up. Results: For both interventions, mean changes on the PSS-10 were significant post-therapy (W8), as at 1-month (W12) and 4-months (W24) follow-ups. The between-group comparison showed no difference at any time point (ps > 0.88). Work-related ruminations significantly decreased in the experimental group with a significant between-group difference at W8 (Δ = -1.83 [-3.57; -0.09], p = 0.04). Posttraumatic stress symptoms significantly decreased in the experimental group with a significant between-group difference at W12 (Δ = -1.41 [-2.68; -0.14], p = 0.03). The decrease in work-related ruminations at W8 mediated the decrease in posttraumatic stress symptoms at W12 (p = 0.048). Conclusion: The "MyHealthToo" online CBT intervention may help reduce ruminations about work and posttraumatic stress symptoms among healthcare workers during a major health crisis. Work-related ruminations may represent a relevant target of online interventions to improve mental health among healthcare workers.

Fibrinolysis as a causative mechanism for bleeding complications on ECMO: a pilot observational prospective study.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is associated with a high risk of bleeding complications. The specific impact of ECMO on fibrinolysis remains unexplored. The objective of the current pilot observational prospective study was to investigate the longitudinal dynamics of fibrinolytic markers - i.e., changes over time - in the context of bleeding events in patients on ECMO. METHODS: Longitudinal dynamics of contact phase components (kininogen and bradykinin) and fibrinolysis markers (tissue-type plasminogen activator [t-PA], plasminogen activator inhibitor-1 [PAI-1], their complexes [t-PA•PAI-1], plasmin-antiplasmin complexes, plasminogen, and D-dimer) were measured in patients undergoing veno-venous and veno-arterial ECMO, before implantation, at 0, 6, and 12 hours post-implantation, and daily thereafter. RESULTS: The cohort consisted of 30 patients (214 ECMO-days). The concentrations of t-PA, D-dimer, plasmin-antiplasmin complexes, PAI-1 and t-PA•PAI-1 complexes were increased, whereas plasminogen decreased compared to normal values. A noteworthy divergence was observed between hemorrhagic and non-hemorrhagic patients: in bleeding patients, D-dimer, plasmin-antiplasmin, t-PA, PAI-1 and t-PA•PAI-1 followed an increasing kinetics before hemorrhage and then decreased to their baseline level; conversely non-bleeding patients showed a decreasing kinetics in these markers. Also, D-dimer and t-PA followed an increasing kinetics in bleeding patients compared to non-bleeding patients (median values for D-dimer dynamics: 1080 vs. -440 ng/mL, p=0.05; t-PA dynamics: 0.130 vs. 0.100 nM, p=0.038), and both markers significantly increased the day before hemorrhage. A t-PA concentration above 0.304 nM was associated with bleeding events (OR 4.92, 95% CI [1.01-24.08], p=0.049). CONCLUSION: Contact activation induces fibrinolysis in ECMO patients, especially in patients experiencing bleeding. This finding supports the role of this mechanism as a possible causal factor for hemorrhages during ECMO and open new avenues for novel therapeutic perspectives. WHAT WE ALREADY KNOW ABOUT THIS TOPIC: Extracorporeal membrane oxygenation (ECMO) is associated with a high risk of bleeding complications due to multiple factors. However, the role of the fibrinolytic system is not well understood in this setting. WHAT THIS ARTICLE TELLS US THAT IS NEW: In patients requiring cardiac and/or pulmonary support with ECMO, D-dimer and tissue plasminogen activator levels were increased with bleeding, findings consistent with fibrinolysis.Although there are multiple causes for fibrinolysis during ECMO, their study suggests that patients who bled had increased contact activation, and may benefit from novel therapeutic agents that inhibit hemostatic activation through this pathway.

PEC-PRO: A new prognostic score from a series of 87 patients with localized perivascular epithelioid cell neoplasms (PEComas) treated with curative intent.

BACKGROUND: Perivascular epithelioid cell neoplasms (PEComas) encompass a heterogeneous family of mesenchymal tumors. Previously described clinicopathologic features aimed at distinguishing benign from malignant variants but lacked prognostic value. METHODS: This retrospective analysis examined clinicopathologic data from patients who had localized PEComa across French Sarcoma Network centers. The authors analyzed 12 clinicopathologic features in a Cox proportional hazard framework to derive a multivariate prognostic risk model for event-free survival (EFS). They built the PEComa prognostic score (PEC-PRO), in which scores ranged from 0 to 5, based on the coefficients of the multivariate model. Three groups were identified: low risk (score = 0), intermediate risk (score = 1), and high risk (score ≥ 2). RESULTS: Analyzing 87 patients who had a median 46-month follow-up (interquartile range, 20-74 months), the median EFS was 96.5 months (95% confidence interval [CI], 47.1 months to not applicable), with 2-year and 5-year EFS rates of 64.7% and 58%, respectively. The median overall survival was unreached, with 2-year and 5-year overall survival rates of 82.3% and 69.3%, respectively. The simplified Folpe classification did not correlate with EFS. Multivariate analysis identified three factors affecting EFS: positive surgical margins (hazard ratio [HR], 5.17; 95% CI, 1.65-16.24; p = .008), necrosis (HR, 3.94; 95% CI, 1.16-13.43; p = .030), and male sex (HR, 3.13; 95% CI, 1.19-8.27; p = 0.023). Four variables were retained in the prognostic model. Patients with low-risk PEC-PRO scores had a 2-year EFS rate of 93.7% (95% CI, 83.8%-100.0%), those with intermediate-risk PEC-PRO scores had a 2-year EFS rate of 67.4% (95% CI, 53.9%-80.9%), and those with high-risk PEC-PRO scores had a 2-year EFS rate of 2.3% (95% CI, 0.0%-18.3%). CONCLUSIONS: The PEC-PRO score reliably predicts the risk of postoperative recurrence in patients with localized PEComa. It has the potential to improve follow-up strategies but requires validation in a prospective trial.

Disseminated intravascular coagulation is strongly associated with severe acute kidney injury in patients with septic shock.

BACKGROUND: Disseminated intravascular coagulation (DIC) worsens the prognosis of septic shock and contributes to multiple organ failure. To date, no data linking DIC and acute kidney injury (AKI) occurrence, severity, and evolution in this setting are available. We aimed at analyzing the association between AKI occurrence, severity and evolution in patients with septic shock-induced DIC. In a prospective monocentric cohort study, consecutive patients, 18 years and older, admitted in the ICU of Strasbourg University Hospital in the setting of systemic hypotension requiring vasopressor related to an infection, without history of terminal chronic kidney disease were eligible. AKI was defined according to the KDIGO classification. DIC diagnosis was based on the International Society on Thrombosis and Haemostasis (ISTH) score. Evolution of AKI was evaluated through the composite endpoint of major adverse kidney events. Only patients with DIC that occurred before or at the time of AKI diagnosis were considered. Univariate and multivariate analysis were performed to determine factors associated with renal outcomes. RESULTS: 350 patients were included, of whom 129 experienced DIC. Patients with DIC were more seriously ill (median SAPS II 64 vs. 56, p < 0.001), and had higher 28-day mortality (43.3% vs. 26.2%, p < 0.001). AKI was more frequent in patients with DIC (86.8% vs. 74.2%, p < 0.005), particularly for the more severe stage of AKI [KDIGO 3 in 58.1% of patients with DIC vs. 30.8% of patients without DIC, p < 0.001, AKI requiring renal replacement therapy (RRT) in 47.3% of patients with DIC vs. 21.3% of patients without DIC, p < 0.001]. After adjustment for confounding factors, DIC occurrence remained associated with the risk of having the more severe stage of AKI with an odds ratio (OR) of 2.74 [IC 95% (1.53-4.91), p < 0.001], and with the risk of requiring RRT during the ICU stay [OR 2.82 (1.53-5.2), p < 0.001]. CONCLUSION: DIC appears to be strongly associated with the risk of developing the more severe form of AKI (stage 3 of the KDIGO classification, RRT requirement), even after adjustment for severity and other relevant factors.

Influence of age and severity of Lenke 5 or 6 idiopathic scoliosis on postoperative quality of life in adult patients.

INTRODUCTION: Thoracolumbar adolescent idiopathic scoliosis can continue to progress beyond skeletal maturity. Ideal timing of surgery remains undefined. Earlier intervention, with shorter instrumentation, incurs early partial loss of lumbar motion. Waiting for progression incurs a greater risk of extensive arthrodesis. The aim of the present study was to assess the quality-of-life impact of age and scoliosis severity at surgery. MATERIAL AND METHODS: Patients with Lenke 5 or 6 adolescent idiopathic scoliosis, aged 16-45years, were analyzed based on a prospective clinical registry. Oswestry Disability Index (ODI) and Scoliosis Research Society (SRS)-22 scores were collected preoperatively and at 6months, 1year and 2years. Coronal and sagittal alignments were measured on full-spine radiographs, and curve flexibility was assessed on bending radiographs. A mixed linear model was used to assess the impact of age, Cobb angle and flexibility on quality of life. RESULTS: Thirty-six patients were included. Mean ODI was 20.5% preoperatively and 13.8% at 2years (p=0.017). Mean SRS-22 was 3.2 preoperatively and 3.9 at 2years (p<0.001). Mean Cobb angle was 56.6° preoperatively and 23.2° at 2years (p<0.001), with mean preoperative reducibility of 68.1%. Age and ODI correlated preoperatively (r=0.6; p<0.001) and at 6months (r=0.5; p=0.002), as did age and SRS-22 (r=-0.6; p<0.001 and r=-0.6; p<0.001, respectively). Linear regression found a significant negative correlation between thoracolumbar Cobb angle and change in SRS-22 at 6months. DISCUSSION: In 16-45 year-olds with Lenke 5 or 6 idiopathic scoliosis, age influenced SRS-22 score. Younger patients had better quality of life both pre- and post-operatively. Curve magnitude influenced postoperative score. The present study suggests that early surgical correction in younger patients, where instrumentation can be shorter, does not impair quality of life. LEVEL OF EVIDENCE: IV; prospective registry study.

In inflammatory myopathies, dropped head/bent spine syndrome is associated with scleromyositis: an international case-control study.

BACKGROUND: Some myopathies can lead to dropped head or bent spine syndrome (DH/BS). The significance of this symptom has not been studied in inflammatory myopathies (IM). OBJECTIVES: To assess the significance of DH/BS in patients with IM. METHODS: Practitioners from five IM networks were invited to report patients with IM suffering from DH/BS (without other known cause than IM). IM patients without DH/BS, randomly selected in each participating centre, were included as controls at a ratio of 2 to 1. RESULTS: 49 DH/BS-IM patients (DH: 57.1%, BS: 42.9%) were compared with 98 control-IM patients. DH/BS-IM patients were older (65 years vs 53 years, p<0.0001) and the diagnosis of IM was delayed (6 months vs 3 months, p=0.009). Weakness prevailing in the upper limbs (42.9% vs 15.3%), dysphagia (57.1% vs 25.5%), muscle atrophy (65.3% vs 34.7%), weight loss (61.2% vs 23.5%) and loss of the ability to walk (24.5% vs 5.1%) were hallmarks of DH/BS-IM (p≤0.0005), for which the patients more frequently received intravenous immunoglobulins (65.3% vs 34.7%, p=0.0004). Moreover, DH/BS-IM patients frequently featured signs and/or complications of systemic sclerosis (SSc), fulfilling the American College of Rheumatology/European Alliance of Associations for Rheumatology criteria for this disease in 40.8% of the cases (vs 5.1%, p<0.0001). Distribution of the myopathy, its severity and its association with SSc were independently associated with DH/BS (p<0.05). Mortality was higher in the DH/BS-IM patients and loss of walking ability was independently associated with survival (p<0.05). CONCLUSION: In IM patients, DH/BS is a marker of severity and is associated with SSc (scleromyositis).

Organizational Benefits of Ultra-Low-Dose Chest CT Compared to Chest Radiography in the Emergency Department for the Diagnostic Workup of Community-Acquired Pneumonia: A Real-Life Retrospective Analysis.

Background and Objectives: Chest radiography remains the most frequently used examination in emergency departments (ED) for the diagnosis of community-acquired pneumonia (CAP), despite its poor diagnostic accuracy compared with ultra-low-dose (ULD) chest computed tomography (CT). However, although ULD CT appears to be an attractive alternative to radiography, its organizational impact in ED remains unknown. Our objective was to compare the relevant timepoints in ED management of CT and chest radiography. Materials and Methods: We conducted a retrospective study in two ED of a University Hospital including consecutive patients consulting for a CAP between 1 March 2019 and 29 February 2020 to assess the organizational benefits of ULD chest CT and chest radiography (length of stay (LOS) in the ED, time of clinical decision after imaging). Overlap weights (OW) were used to reduce covariate imbalance between groups. Results: Chest radiography was performed for 1476 patients (mean age: 76 years [63; 86]; 55% men) and ULD chest CT for 133 patients (mean age: 71 [57; 83]; 53% men). In the weighted population with OW, ULD chest CT did not significantly alter the ED LOS compared with chest radiography (11.7 to 12.2; MR 0.96 [0.85; 1.09]), although it did significantly reduce clinical decision time (6.9 and 9.5 h; MR 0.73 [0.59; 0.89]). Conclusion: There is real-life evidence that a strategy with ULD chest CT can be considered to be a relevant approach to replace chest radiography as part of the diagnostic workup for CAP in the ED without increasing ED LOS.

Validity Evidence of A Screening Tool for Early Detection of Clinical Crisis-Related Anxiety Amongst Medical Students.

Construct: Psychological distress among students is a growing concern in medical education, even more so with the advent of COVID-19 pandemic. Anxiety is among students' mental health issues. High and persistent anxiety has many negative impacts on students' academic and personal life. Early detection is essential for timely intervention. Background: Currently, medical student anxiety is assessed using tools primarily designed for psychiatric purposes. Despite their excellent validity evidence, these tools contain sensitive items and do not explore stressors related to clinical activities. There is a need for contextualized tools to better identify anxiety-provoking factors specific to the medical education environment. Approach: We previously developed the Crisis Experience Rating Scale (CERS-7), a short screening tool to identify early on anxious students participating in clinical activities during the first wave of the COVID-19 pandemic. The present study sought to produce further validity evidence for the CERS-7. Medical students in their clinical years at two Swiss and one French medical school, all involved in COVID-19 clinical activity during the second wave of the pandemic, completed the CERS-7 and the State Anxiety Inventory (STAI-A), the best known and widely used tool to measure for general anxiety. We evaluated internal structure using confirmatory factor analysis (CFA) and relation to other variables using linear regression (LR) and receiver operating characteristic (ROC) curves with thresholds defined using the Youden index. Findings: There were 372 participants. CFA confirmed the two-factor structure of the CERS-7 scale from first-wave dataset. The CERS-7 total scale and subscales demonstrated validity evidence in relationship to the STAI-A scores and categories. A CERS-7 total scale score < 27.5 identified 93% of severely anxious students. Conclusion: The CERS-7 produces reliable scores to use for monitoring anxiety status when assigning students to clinical settings as well as for improving training conditions during clinical crisis.

Influence of systemic sclerosis on periodontal health: A case-control study.

AIM: Patients with systemic sclerosis (SSc) present various clinical and radiological oral manifestations. However, precise evaluation of the oral features associated with diffuse cutaneous SSc (dcSSc) and limited cutaneous SSc (lcSSc) is limited. The objective of this study was to evaluate the periodontal ligament (PDL) surface in SSc patients in comparison with controls. Assessment of oral-health-related quality of life (OHRQoL) and the levels of different biomarkers in the gingival crevicular fluid (GCF) was performed. MATERIALS AND METHODS: SSc patients and matched controls underwent standardized oral examination and cone-beam computed tomography (CBCT). Levels of interleukin-6 (IL-6), chemokine (C-X-C motif) ligand 4 (CXCL-4) and matrix metalloproteinase-9 (MMP-9) in the GCF were determined by enzyme-linked immunosorbent assay. PDL surface was measured on CBCT axial views. OHRQoL was quantified using the Mouth Handicap in SSc Scale (MHISS). RESULTS: Thirty-nine SSc patients and 39 controls were included. SSc patients exhibited increased PDL surface, higher number of missing teeth as well as elevated IL-6, MMP-9 and CXCL-4 levels. Reduced mouth opening was observed in dcSSc but not in lcSSc patients. MHISS score was higher in dcSSc than in lcSSc patients. Although worse periodontal parameters were found in both subgroups compared with controls, dcSSc patients presented lower gingival inflammation. CONCLUSIONS: SSc is associated with PDL space widening, impaired oral health and OHRQoL.

Cefepime vs carbapenems for treating third-generation cephalosporin-resistant AmpC ß-lactamase-hyperproducing Enterobacterales bloodstream infections: a multicenter retrospective study.

OBJECTIVES: AmpC ß-lactamase-hyperproducing Enterobacterales (ABLHE) bloodstream infections (BSI) are emerging and leading to therapeutic challenges worldwide. Prescriptions of carbapenems may lead to the emergence of resistance. This study aimed to compare cefepime with carbapenems for the treatment of third-generation cephalosporin-resistant ABLHE BSI. METHODS: This retrospective multicenter study included patients with ABLHE BSI from two tertiary hospitals in France, between July 2017 and July 2022. Non-AmpC-producing Enterobacterales, extended-spectrum ß-lactamase, and carbapenemase-producing Enterobacterales were excluded. Cefepime was prescribed only in case of minimal inhibitory concentration ≤1 mg/l. The primary outcome was 30-day in-hospital mortality from the date of index blood culture. Secondary outcomes were infection recurrence and treatment toxicity. An inverse probability of treatment weighting approach was used to balance the baseline characteristics between the two groups. RESULTS: We analyzed 164 BSI, which included 77 in the cefepime group and 87 in the carbapenem group. In the weighted cohort, the 30-day mortality rates were similar between the cefepime group (23.3%) and the carbapenem group (19.6%) with a relative risk of 1.19 (95% confidence interval, 0.61-2.33 P = 0.614). No significant difference in recurrence or toxicity was found between the two groups. CONCLUSION: This study adds evidence in favor of the use of cefepime for treating third-generation cephalosporin-resistant ABLHE BSI in case of minimal inhibitory concentration ≤ 1 mg/l, which could spare carbapenems.

Refining Incidence and Characteristics of Inflammatory Myopathies: A Quadruple-Source Capture-Recapture Survey Using the 2017 European League Against Rheumatism/American College of Rheumatology Classification Criteria.

OBJECTIVE: Inflammatory myopathies (IM), characterized by muscle inflammation and weakness, are rare systemic diseases. Our previous study estimated an IM incidence rate of 7.98 cases per million people per year (95% confidence interval 7.38-8.66) and highlighted important variations that were likely because of methodologic issues rather than true epidemiologic differences. In this study, we aimed to refine the incidence of IM, using the 2017 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for IM and a quadruple-source capture-recapture method during a 6-year period in Alsace, France, a region with a population of 2 million having benefits of good access to health care and accredited IM referral centers. METHODS: Clinical data of potential IM patients were obtained from 4 sources (general practitioners and community specialists, public and private hospital records, public and private laboratories, and archives from the pathology department). Patients residing in Alsace and who fulfilled the 2017 EULAR/ACR criteria for IM between January 1, 2006, and January 1, 2013, were included. We corrected potentially incomplete ascertainment of cases with capture-recapture analyses. We studied both spatial and temporal distributions of incidence of IM. We also assessed systemic manifestations of the disease. RESULTS: Our review of 1,742 potential cases identified 106 patients with IM. No spatial or temporal heterogeneity was observed. Use of log-linear models showed an estimated 14.9 additional missed cases. Thus, the incidence rate of IM was 8.22 new cases per million inhabitants per year (95% confidence interval 6.76-9.69). Extramuscular manifestations other than dermatomyositis rash were frequently recorded. CONCLUSION: The stringent methodology used in our study provides an accurate estimation of the incidence of IM. This study also demonstrates, in a population-based cohort, the systemic nature of IM.

Occurrence of Severe Arrhythmias in Patients with Non-ST Elevation Acute Coronary Syndrome (NSTE-ACS): A Retrospective Study.

BACKGROUND: Non-ST elevation acute coronary syndrome (NSTE-ACS) is one of the most frequent manifestations of coronary artery disease. The occurrence of serious heart rhythm disorders (SHRDs) in NSTE-ACS is not well documented. However, continuous heart rhythm monitoring is recommended during the initial management of NSTE-ACS. The targeted monitoring of patients at greater risk for SHRDs could facilitate patients' care in emergency departments (EDs) where the flow of patients is continuously increasing. METHODS: This retrospective single-center study included 480 patients from emergency and cardiology departments within the Strasbourg University Hospital between 1 January 2019 and 31 December 2020. The objective was to estimate the frequency of the occurrence of SHRDs among patients with NSTE-ACS. The secondary objective was to highlight the factors associated with a higher risk of SHRDs. RESULTS: The proportion of SHRDs during the first 48 h of hospital care was 2.3% (CI95%: 1.2-4.1%, n = 11). Two time periods were considered: before coronary angiography (1.0%), and during, or after coronary angiography (1.3%). In the first group, two patients required immediate treatment (0.4% of the patients) and no death occurred. In the univariate analysis, the variables significantly associated with SHRDs were age, anticoagulant medication, a decrease in glomerular filtration rate, plasmatic hemoglobin, and left ventricle ejection fraction (LVEF), and an increase in plasmatic troponin, BNP, and CRP levels. In the multivariable analysis, plasmatic hemoglobin > 12 g/dL seemed to be a protective factor for SHRDs. CONCLUSIONS: In this study, SHRDs were rare and, most often, spontaneously resolved. These data challenge the relevance of systematic rhythm monitoring during the initial management of patients with NSTE-ACS.

Anatomical variations of the cavernous Internal Carotid Artery: Validation of an MRI-based classification.

OBJECTIVE: Variations of the cavernous Internal Carotid Artery (ICA) angulation (C4-bend) have been classified into 4 anatomical subtypes with particular surgical relevance, as a very angulated ICA comes in closest contact with the pituitary gland leading to higher risk of iatrogenic vascular injury. This study aimed to validate this classification using current routine imaging techniques. METHODS: The different cavernous ICA bending angles were measured on 109 MRI TOF sequences, within a retrospective database of patients with no sellar lesions. Each ICA was classified into one of 4 anatomical subtypes as already defined in a previous study [1]. Interrater agreement was assessed by a Kappa Correlation Coefficient. RESULTS: Kappa Correlation Coefficient was of 0.90 [0.82-0.95], validating the strong level of agreement between all observers when using the present classification. CONCLUSION: Classification of the cavernous ICA in 4 subtypes appears statistically valid on routinely used pre-operative MRI, providing an efficient tool to estimate the vascular iatrogenic risk prior to endoscopic endonasal transsphenoidal surgery.

Adequacy of sedation analgesia to support the comfort of neonates undergoing therapeutic hypothermia and its impact on short-term neonatal outcomes.

Objectives: We aimed to evaluate (1) whether sedation analgesia (SA) used during therapeutic hypothermia (TH) was efficient to support the wellbeing of neonates with hypoxic-ischemic encephalopathy, (2) the SA level and its adjustment to clinical pain scores, and (3) the impact of inadequate SA on short-term neonatal outcomes evaluated at discharge. Methods: This was an observational retrospective study performed between 2011 and 2018 in two level III centers in Alsace, France. We analyzed the wellbeing of infants by using the COMFORT-Behavior (COMFORT-B) clinical score and SA level during TH, according to which we classified infants into four groups: those with excess SA, adequate SA, lack of SA, and variability of SA. We analyzed the variations in doses of SA and their justification. We also determined the impact of inadequate SA on neonatal outcomes at discharge by multivariate analyses with multinomial regression, with adequate SA as the reference. Results: A total of 110 patients were included, 89 from Strasbourg university hospital and 21 from Mulhouse hospital. The COMFORT-B score was assessed 95.5% of the time. Lack of SA was mainly found on the first day of TH (15/110, 14%). In all, 62 of 110 (57%) infants were in excess of SA over the entire duration of TH. Most dose variations were related to clinical pain scores. Inadequate SA was associated with negative short-term consequences. Infants with excess of SA had a longer duration of mechanical ventilation [mean ratio 1.46, 95% confidence interval (CI), 1.13-1.89, p = 0.005] and higher incidence of abnormal neurological examination at discharge (odds ratio 2.61, 95% CI, 1.10-6.18, p = 0.029) than infants with adequate SA. Discussion: Adequate SA was not easy to achieve during TH. Close and regular monitoring of SA level may help achieve adequate SA. Excess of SA can be harmful for newborns with hypoxic-ischemic encephalopathy who are undergoing TH.

Comparison of three antithrombotic strategies for emergent carotid stenting during stroke thrombectomy: a multicenter study.

BACKGROUND: Periprocedural antithrombotic treatment is a key determinant for the risk-benefit balance of emergent carotid artery stenting (eCAS) during stroke thrombectomy. We aimed to assess the safety and efficacy of three types of antithrombotic treatment. METHODS: Retrospective review of prospectively collected endovascular databases in four comprehensive stroke centers, including consecutive cases of eCAS for tandem lesion strokes between January 2019 and July 2021. During this period, each center prospectively applied one of three periprocedural protocols: (a) two centers administered aspirin (250 mg IV); (b) one center administered aspirin and heparin (bolus+24 hours infusion); and (c) one center applied an aggressive antiplatelet strategy consisting of aspirin and clopidogrel (loading doses), with added intravenous tirofiban if in-stent thrombosis was observed during thrombectomy. Dichotomized comparisons of outcomes were performed between aggressive versus non-aggressive strategy (aspirin±heparin) and aspirin+heparin versus aspirin-alone groups. RESULTS: Among 161 included patients, 62 received aspirin monotherapy, 38 aspirin+heparin, and 61 an aggressive treatment. Aggressive antiplatelet treatment was associated with an increased rate of excellent (modified Thrombolysis in Cerebral Infarction (mTICI) 2c-3) recanalization and reduced carotid stent thrombosis at day 1 (3.5% vs 16.3%), compared with non-aggressive strategy. There were no significant differences in hemorrhagic transformation or 90-day mortality. There was a tendency towards better clinical outcome with aggressive treatment, without reaching statistical significance. Addition of heparin to aspirin was not associated with an increased rate of carotid stent patency. CONCLUSIONS: Aggressive antiplatelet treatment was associated with improved intracranial recanalization and carotid stent patency, without safety concerns. These findings have implications for randomized trials and may be of utility for clinicians when making antithrombotic treatment choices.

Conservative versus aggressive antiplatelet strategy for emergent carotid stenting during stroke thrombectomy.

BACKGROUND: There is no consensus regarding optimal antiplatelet regimen for emergent carotid stenting during stroke thrombectomy. We aimed to assess the safety and efficacy of an aggressive periprocedural antiplatelet strategy focused on preserving stent patency, in comparison with conservative antiplatelet strategy consisting of aspirin monotherapy. MATERIALS AND METHODS: Retrospective review of a prospectively collected database in a comprehensive stroke center, including all cases of emergent carotid stenting for tandem lesions stroke between 01.03.2012-01.06.2021. Aggressive antiplatelet strategy consisted of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel loading doses, with added intravenous (IV) tirofiban if in-stent thrombosis was observed during thrombectomy. Clinical and radiological outcomes were compared between conservative and aggressive antiplatelet treatment groups using inverse probability of treatment weighting (IPTW) analysis based on propensity scores. RESULTS: We included 132 cases (76.5% atheroma, 22.7% dissection, 0.7% carotid web). Forty-five patients (34%) cases received conservative antiplatelet therapy. The remaining 87 (65.9%) received aggressive antiplatelet therapy: 66 (75.8%) treated with DAPT, 21 (24.1%) with DAPT and tirofiban. Periprocedural heparin was avoided in all cases. In adjusted analysis of the weighted samples, aggressive antiplatelet strategy was associated with improved carotid stent patency (aOR 0.23, 95% CI 0.07-0.80, p = 0.021), higher proportion of moderate clinical outcome (mRS ≤ 3, aOR 2.72, 95% CI 1.01-7.30, p = 0.04), with no significant differences in mortality and hemorrhagic transformation (HT) rates. CONCLUSIONS: In this retrospective study, aggressive periprocedural antiplatelet strategy led to improved stent patency and clinical outcomes, without increased HT. Further prospective randomized research is warranted to identify the optimal combination of antiplatelet agents for emergent carotid stenting in the setting of acute stroke.

Diffusion-weighted and gadolinium-enhanced dynamic MRI in parotid gland tumors.

PURPOSE: To evaluate the value of diffusion-weighted imaging and dynamic contrast-enhanced MRI for the diagnosis of parotid gland tumors. METHODS: Retrospective review of patients with surgically treated parotid tumors between January 2009 and June 2020, who underwent a preoperative parotid gland MRI including standard morphological sequences, diffusion-weighted echoplanar imaging with apparent diffusion coefficient measurement and T1-weighted gadolinium-enhanced dynamic MRI sequences with Fat Saturation. The lesion was classified between malignant vs benign and precisions regarding its histological type were given when possible. Imaging findings were compared with pathology results. RESULTS: Inclusion of 133 patients (mean age: 53 years). Multiparametric MRI had a sensitivity of 90.3%, a specificity of 77.5%, an overall accuracy of 80.5%, a positive predictive value of 54.9% and a negative predictive value of 96.3% to differentiate benign parotid tumor from malignant ones. Specificity (85.5%) and positive predictive value (67.6%) were improved for cases, where anatomical and functional MRI characteristics were conclusive and consistent with clinical findings. CONCLUSIONS: Combining diffusion-weighted and gadolinium-enhanced dynamic sequences, in addition to morphological ones enables high (> 90%) sensitivity to detect malignant parotid gland tumors. It also gives the possibility to characterize pleomorphic adenomas and Warthin tumors and to avoid fine-needle aspiration in cases of typical imaging presentation and reassuring clinical findings.

Cerebrospinal Fluid Lactate and Glucose Levels as Predictors of Symptomatic Delayed Cerebral Ischemia in Patients with Aneurysmal Subarachnoid Hemorrhage.

BACKGROUND: Aneurysmal subarachnoid hemorrhage (aSAH) is a complex neurovascular syndrome with profound systemic effects associated with high rates of disability and mortality. Delayed cerebral ischemia (DCI), which encompasses all neurobiological events occurring in the subacute-late stage after aSAH, has a complex pathogenesis and can occur in the absence of instrumental vasospasm. Our aim was to assess the correlation between cerebrospinal fluid (CSF) lactate and glucose levels measured on the second or third day after aSAH with clinical deterioration caused by DCI and with 3-month functional outcome. METHODS: This prospective study included all aSAH patients admitted between January 2020 and December 2021 who underwent external ventricular drain placement and CSF lactate and glucose measurement. RESULTS: Among 133 aSAH patients, 48 had an external ventricular drain placed and early CSF lactate and glucose assessment. Independent predictors of symptomatic DCI were World Federation of Neurosurgical Societies grade IV-V (adjusted odds ratio [aOR] 25.8, 95% confidence interval [CI] 2.9-649.2, P = 0.012), elevated CSF glucose (aOR 28.8, 95% CI 3.3-775.2, P = 0.010), and elevated CSF lactate (aOR 14.7, 95% CI 1.9-205.7, P = 0.018). The only independent predictor of 3-month functional outcome was occurrence of symptomatic DCI (aOR 0.02, 95% CI 0.0-0.2, P = 0.01). CONCLUSIONS: Elevated CSF lactate and glucose levels in the first 3 days following aSAH were independent predictors of subsequent DCI-related neurological impairment; the presence of instrumental vasospasm was not significantly correlated with DCI after multivariate adjustment. CSF lactate and glucose monitoring may represent a point-of-care test, which could potentially improve prediction of subacute neurological worsening and guide therapeutic choices. Further research with larger prospective cohorts is warranted.
