    Abstract A simple and easy way is proposed for the fabrication of a highly attenuating composite material for underwater acoustics. The approach involves the introduction of porous polymer beads into a polyurethane matrix. The porous beads are prepared through an emulsion-templating approach, and two different processes are used. The first one uses microfluidics to synthesize beads of controlled diameter and porosity. The control over the bead size allows the selection of the frequency range where the material exhibits the highest acoustic attenuation. The second one uses a double emulsion approach and allows for the production of much larger quantities of beads. Both approaches yield materials exhibiting much higher acoustic absorption than the one obtained using the most commonly used micro-balloon inclusion. We present both the synthesis procedures and the structural and acoustic characterizations of the beads and the final acoustic materials.

    Abstract Objective: Immune checkpoint inhibitor (ICI) antibodies constitute a new generation of cancer treatments, associated with immune-related adverse events (irAEs). A previous retrospective study of patients with metastatic melanoma (treated mostly with anti-CTLA4 antibodies) reported a serious infection rate of 7.3%. The main risk factors were corticoids and infliximab use. We sought to describe infections and risk factors among patients receiving anti-PD-1/PD-L1 ICIs.
    Patients and methods: We reviewed 200 medical records sampled randomly from a French prospective registry, which collates patients treated with anti-PD-1/PD-L1 ICIs. We recorded demographic data, the occurrence of irAEs, immunosuppressant use, and the outcome.
    Results: Thirty-six patients (18%) experienced an infection by a median (interquartile range) of 47 (19.2-132) days after initiation of the ICI. Twenty-one patients (58.3%) had a lung infection, seven (19.4%) had a skin infection, seven (19.4%) had a urinary tract infection, and all of them received antibiotics. The infection was generally mild, and the patients were treated as outpatient. There were no infection-related deaths and no opportunistic infection. Sixty percent of the patients were being treated for metastatic melanoma and 35.5% for non-small cell lung cancer, and 106 irAEs (mostly grade II) were reported. Forty-seven patients received steroids for cancer symptoms or irAEs, and five received immunosuppressants during the immunotherapy. We did not observe any association between corticosteroid or immunosuppressant use and the occurrence of an infection.
    Conclusion: The infection rate in patients treated with an anti-PD-1/PD-L1 ICI was 18%, without any severe or opportunistic infection. The occurrence of an infection was not associated with corticosteroid or immunosuppressant use.

    Abstract Babesiosis is a tick-borne infectious disease, caused by an intraerythrocytic parasite of the genus Babesia. It has clinical, biological and microbiological similarities with Plasmodium related infections. In rare cases, babesiosis may be complicated by hemophagocytic lymphohistiocytosis, which occurs preferentially in the immunodeficient patient. We report here the case of a non-immunocompromised patient living in Manhattan, New York hospitalized for a complicated babesiosis of a hemophagocytic lymphohistiocytosis. After 7 days of hospitalization and treatment by azithromycin 500 mg/day and atovaquone 750 mg twice a day, the patient was discharged with an improvement in clinical symptoms and biological parameters.

    Abstract Background: Ceftriaxone and cefotaxime share a similar antibacterial spectrum and similar indications but have different pharmacokinetic characteristics. Ceftriaxone is administered once daily and 40% of its clearance is by biliary elimination, whereas cefotaxime requires three administrations per day and shows less than 10% biliary elimination. The high biliary elimination of ceftriaxone suggests a greater impact of this antibiotic on the gut microbiota than cefotaxime. The objective of this study was to compare the impact of ceftriaxone and cefotaxime on the gut microbiota.
    Methods: A prospective clinical trial was performed that included 55 patients treated with intravenous ceftriaxone (1 g/24 h) or cefotaxime (1 g/8 h) for at least 3 days. Three fresh stool samples were collected from each patient (days 0, 3, and 7 or at the end of intravenous treatment) to assess the emergence of third-generation cephalosporin (3GC)-resistant Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae, Pseudomonas aeruginosa, toxigenic Clostridioides difficile, and vancomycin-resistant enterococci.
    Results: The emergence of 3GC-resistant gram-negative enteric bacilli (Enterobacteriaceae) (5.9% vs 4.7%, p > 0.99), Enterococcus spp, and non-commensal microorganisms did not differ significantly between the groups. Both antibiotics reduced the counts of total gram-negative enteric bacilli and decreased the cultivable diversity of the microbiota, but the differences between the groups were not significant.
    Conclusion: No significant difference was observed between ceftriaxone and cefotaxime in terms of the emergence of resistance.

    Abstract Background: Numerous retrospective studies and reviews have reported a positive association between immune-related adverse events (irAEs) and survival in non-small cell lung cancer (NSCLC) and melanoma patients treated with immune checkpoint blockers (ICBs). However, some results are controversial and the studies, whose results converge, should be interpreted cautiously because most of them do not deal appropriately with the immortal-time bias. Here, we report an observational real-life study of the association between prospectively collected irAEs and survival of patients treated with ICBs while dealing with the immortal-time bias.
    Methods: Data from patients treated at Gustave Roussy from June 2014 to October 2017 with anti-PD-(L)1 antibodies for a melanoma or NSCLC have been prospectively collected in the REISAMIC database, a pharmacovigilance registry dedicated to irAEs. Adverse events of grade 2 and higher were collected prospectively. To study the association between the occurrence of irAEs and survival, we used both a landmark analysis and a Cox regression model with time-dependent covariate.
    Results: 577 patients were treated with anti-PD-(L)1 antibodies for melanoma (60.3 %) or NSCLC (39.7 %). The occurrence of an irAE was significantly associated with improved overall survival (OS): HR 0.56, 95 % CI [0.41; 0.75], p = 0.0001 and progression-free survival (PFS): HR 0.63, 95 % CI [0.47; 0.83], p = 0.001 using a Cox regression model with time-dependent covariate. In a 12-week landmark analysis, median OS was 21.2 months (95 % CI, 12.2 to 35.7) and 16.4 months (95 % CI, 12.4 to 21.3) p = 0.26 and median PFS was 14.3 months (95 % CI, 9.5 to 24.6) and 13.4 months (95 % CI, 10.2 to 18.3) p = 0.66, for patients with and without irAEs, respectively.
    Conclusions: In our real-life study of patients with melanoma and NSCLC treated with anti-PD-(L)1 antibodies, we confirm that irAEs are associated with improved survival using a time-varying Cox regression model. Analysis with a landmark method showed no difference in OS or PFS between patients who experienced irAE during the first 12 weeks of treatment and those who did not. Retrospective analysis and reviews including studies that do not deal with the immortal-time bias and studies insufficiently powered for a landmark analysis should be interpreted with caution.

    Abstract There is no microbiological gold standard for childhood tuberculosis (TB) diagnosis. The paucibacillary nature of the disease, challenges in sample collection in young children, and the limitations of currently available microbiological tests restrict microbiological confirmation of intrathoracic TB to the minority of children. Recent WHO guidelines recommend the use of novel rapid molecular assays as initial diagnostic tests for TB and endorse alternative sample collection methods for children. However, the uptake of these tools in high-endemic settings remains low. In this review, we appraise historic and new microbiological tests and sample collection techniques that can be used for the diagnosis of intrathoracic TB in children. We explore challenges and possible ways to improve diagnostic yield despite limitations, and identify research gaps to address in order to improve the microbiological diagnosis of intrathoracic TB in children.

    Abstract Introduction: Association of high body mass index (BMI) with longer survival has been reported in patients on immune checkpoint inhibitors (ICIs), but results are inconsistent. This 'obesity paradox' is potentially confounded by the effects of BMI change over time and of skeletal muscle depletion.
    Methods: We conducted a secondary analysis of a prospective cohort, including consecutive patients receiving ICI treatment for melanoma (n = 411) and non-small cell lung cancer (NSCLC) (n = 389) in routine care.
    Results: In the univariable analysis of the entire population, overweight/obesity (BMI ≥ 25 kg/m
    Conclusions: The so-called 'obesity paradox', counterintuitive association between high BMI and longer survival, vanished when controlling for confounders, such as type of cancer, and manifestations of depletion (WL and reduced skeletal muscle mass).
