    Abstract The European Rosetta mission has been following comet 67P/Churyumov-Gerasimenko for 2 years, studying the nucleus and coma in great detail. For most of these 2 years the Rosetta Orbiter Sensor for Ion and Neutral Analysis (ROSINA) has analysed the volatile part of the coma. With its high mass resolution and sensitivity it was able to not only detect deuterated water HDO, but also doubly deuterated water, D

    Abstract With an increasing number of patients eligible for immune checkpoint inhibitors, the incidence of immune-related adverse events (irAEs) is on the rise. Dermatologic immune-related adverse events (D-irAEs) are the most common and earliest to manifest, often with important downstream consequences for the patient. Current guidelines lack clarity in terms of diagnostic criteria for D-irAEs. The goal of this project is to better define D-irAE for the purposes of identification, diagnosis, and future study of this important group of diseases.The objectives of this project were to develop consensus guidance for an approach to D-irAEs including disease definitions and severity grading. Knowing that consensus among oncologists, dermatologists, and irAE subspecialists would be critical for usability, we formed a Dermatologic irAE Disease Definition Panel. The panel was composed of 34 experts, including oncologists, dermatologists, a rheumatologist, and an allergist/immunologist from 22 institutions across the USA and internationally. A modified Delphi consensus process was used, with two rounds of anonymous ratings by panelists and two virtual meetings to discuss areas of controversy. Panelists rated content for usability, appropriateness, and accuracy on 9-point scales in electronic surveys and provided free text comments. A working group aggregated survey responses and incorporated them into revised definitions. Consensus was based on numeric ratings using the RAND/UCLA Appropriateness Method with prespecified definitions.Following revisions based on panelist feedback, all items received consensus in the second round of ratings. Consensus definitions were achieved for 10 core D-irAE diagnoses: ICI-vitiligo, ICI-lichen planus, ICI-psoriasis, ICI-exanthem, ICI-bullous pemphigoid, ICI-Grover's, ICI-eczematous, ICI-eruptive atypical squamous proliferation, ICI-pruritus without rash, and ICI-erosive mucocutaneous. A standard evaluation for D-irAE was also found to reach consensus, with disease-specific exceptions detailed when necessary. Each disorder's description includes further details on disease subtypes, symptoms, supportive exam findings, and three levels of diagnostic certainty (definite, probable, and possible).These consensus-driven disease definitions standardize D-irAE classification in a useable framework for multiple disciplines and will be the foundation for future work. Given consensus on their accuracy and usability from a representative panel group, we anticipate that they can be used broadly across clinical and research settings.

    Abstract Die Rolle von Mikronährstoffen wie Vitamin C, Vitamin D oder Zink in der Prävention und Therapie von Erkältungskrankheiten wird seit Langem diskutiert. Die Evidenzlage hierzu ist gemischt, was der Heterogenität der Studienpopulationen, dem oftmals fehlenden Erregernachweis sowie der unterschiedlichen Dauer, Frequenz und Dosis der Mikronährstoffgabe geschuldet ist. Festgehalten werden kann, dass es sinnvoll ist, die Supplementation individuell an den Ernährungsstatus, an Grunderkrankungen und Laborparameter anzupassen. Ein Vitamin-D-Mangel sollte ausgeglichen werden. Von einer Vitamin-C-Supplementation profitieren insbesondere Personen, die unter hohem körperlichen Stress stehen, sowie jene mit Exposition gegenüber Menschen mit akuten Atemwegsinfektionen.

    Abstract Purpose: Mitotane is the only chemotherapeutic agent available for the treatment of adrenocortical carcinoma (ACC), however, the anti-neoplastic efficacy is limited due to several side-effects in vivo. There is, therefore, a need of exploring for new anti-tumoral agents which can be used either alone or in combination with mitotane. The active vitamin D metabolite 1α,25-dihydroxyvitamin D
    Methods and results: Multiple concentrations of mitotane and 1α,25(OH)
    Conclusion: Our results show an additive effect of mitotane and 1α,25(OH)

    Title translation Diagnosis and treatment of catheter-related bloodstream infection in hemodialysis: 10 years later.
    Abstract Patients in hemodialysis on central venous catheter as vascular access are at risk of infections. Catheter-related bloodstream infection is one of the most serious catheter-complications in hemodialysis patients. Its clinical and microbiological diagnosis is challenging. The implementation of empiric antibiotic therapy is based on old recommendations proposing the combination of a molecule targeting methicillin-resistant Staphylococcus aureus and a betalactamin active on P. aeruginosa, and also adapting this probabilistic treatment by carrying out a microbiological register on a local scale, which is rarely done. In our hemodialysis center at Bordeaux University Hospital, an analysis of the microorganisms causing all catheter-related bloodstream infection over the period 2018-2020 enabled us to propose, in agreement with the infectious disease specialists, an adapted probabilistic antibiotic therapy protocol. This approach allowed us to observe a low incidence of meticillinoresistance of Staphylococcus. For catheters inserted more than 6 months ago, we observed no Staphylococcus, no multi-resistant Pseudomonas, and only 2% of Enterobacteria resistant to cephalosporins. A frequent updating of the microbiological epidemiology of catheter-related bloodstream infection, in partnership with the infectious diseases team in each hemodialysis center, allowing an adaptation of the probabilistic antibiotic therapy, and seems to have a good feasibility. This strategy might favor the preservation of microbial ecology on an individual and collective scale in maintenance hemodialysis patients.

    Abstract Objective: To determine whether perioperative vitamin D levels are predictive of postoperative hypocalcemia in patients receiving thyroidectomy.
    Study design: Single center retrospective study.
    Subjects and methods: This study included all patients receiving total or completion thyroidectomy between January 2007 and March 2017 at a single tertiary care hospital. 25-Hydroxyvitamin D (25[OH]D) levels were measured within 42 days prior to surgery or 1 day postoperatively. Hypocalcemia was defined as an adjusted serum calcium <8.0 mg/dL (based on albumin levels) or symptomatic hypocalcemia. Univariate analysis was performed with a 2-sample
    Results: A total of 517 subjects were included in the study, 15.7% (n = 81) of whom experienced postoperative hypocalcemia with a mean ± SD serum calcium level of 7.6 ± 0.5 mg/dL as compared with 8.9 ± 0.5 mg/dL in the normocalcemic population (
    Conclusion: Using a single-center retrospective study design, we demonstrated that 25(OH)D level is a significant predictor of postoperative hypocalcemia after thyroidectomy.

    Abstract Objective: To evaluate the use of preoperative vitamin D levels and postoperative vitamin D supplementation among endocrinologists for the prevention of post-thyroidectomy hypocalcaemia.
    Methods: Endocrinologist members of the American Thyroid Association (ATA) were contacted via email to complete a 21-question survey, which included both questions about demographic information, and preventing and managing postoperative hypocalcaemia after thyroidectomy. Univariate and multivariate analysis was performed to determine the respondents' use of preoperative vitamin D levels, dose and duration of preoperative vitamin D repletion, decision to delay surgery for low vitamin D levels in the case of a benign or malignant disease, and routine prescription of postoperative calcium or vitamin D supplementation.
    Results: 225 endocrinologists who were ATA members responded to the questionnaire. When compared to endocrinologists practicing in other countries, those that practice in the United States were 2.5 times more likely to check preoperative vitamin D levels (95% CI[1.404, 4.535], P = .002), significantly more likely to replete vitamin D deficient patients with high-dose vitamin D (ie ≥50K IU/week), 4.458 times more likely to prescribe prophylactic supplemental calcium (95% CI[2.446, 8.126]; P < .0001) and 3.48 more likely to prescribe supplemental vitamin D (95% CI [1.906, 6.355]; P < .0001). Endocrinologists who have been in practice for >10 years were also 1.915 times more likely to prescribe supplemental vitamin D (95% CI (1.080, 3.395); P = .0263). Physicians that treat >50 thyroidectomy cases/year were 2.083 more likely to recommend a vitamin D repletion duration of >1 month than those that treat ≤50 cases/year ([1.036, 4.190], P = .0395). Lastly, if the patient has low preoperative vitamin D levels, 47.05% of respondents chose to delay surgery in a benign disease, while only 11.61% of respondents would do so in a case of malignant disease.
    Conclusions: Approximately one-half of surveyed endocrinologists reported using preoperative vitamin D levels to assess a patient's risk for post-thyroidectomy hypocalcaemia. Endocrinologists practicing in the United States, compared to those practicing in other countries, were more likely to both test for preoperative vitamin D levels and to recommend prophylactic post-thyroidectomy calcium and vitamin D supplementation.
