Introduction La nouvelle pandemie mondiale (COVID19) causee par le coronavirus 2 du syndrome respiratoire aigu severe (SRAS-CoV-2) est responsable de nombreux deces dans le monde entier au cours des derniers mois. Au cours des formes graves, il a ete note une reponse inflammatoire exageree connue sous le nom de “orage cytokinique”. Ceci a souleve la question de la sensibilite et de la gravite de l’infection par le SRAS-CoV2 chez les patients presentant une hyperactivation genetique de l’immunite innee tels que la fievre mediterraneenne familiale (FMF). En outre, les patients avec FMF prennent de la colchicine au long cours, medicament qui a ete teste chez des patients infectes par le SRAS-CoV2 avec des resultats contradictoires [1] . Patients et methodes Etude menee sur l’infection par le SRAS-CoV2 chez les patients atteints de FMF suivis dans 2 sites du centre de reference national des maladies autoinflammatoires en region parisienne et inclus dans la JIR cohorte, une base de donnees europeenne multicentrique. Les patients adultes et pediatriques inclus repondaient aux criteres internationaux de FMF et avaient un diagnostic genetique confirme. Resultats Les patients identifies (n = 627) ont ete invites a repondre a un bref questionnaire soit en consultation, soit par telephone, soit par courrier electronique sur une possible infection par le SARS-CoV2 pendant la periode de mars a juin 2020 ; 342 patients ont repondu a l’enquete. Le diagnostic etait retenu si le patient presentait des symptomes cliniques avec PCR ou serologie positive ou scanner thoracique typique. Au total, 27 patients FMF (7,8 % des repondants ; sexe ratio 1/1) ont contracte le virus. Tous les 27 patients FMF-COVID+ sauf un prenaient de la colchicine quotidiennement depuis une periode mediane de 23 ans, la dose moyenne de colchicine etait de 1 mg/jour. Quatre recevaient en plus un inhibiteur de l’IL-1. Parmi les 27 patients FMF-COVID+, sept symptomatiques ont ete hospitalises (25 %) et six ont eu besoin d’oxygene ; trois (11 %) ont developpe un syndrome de detresse respiratoire aigue necessitant des soins intensifs pour une ventilation mecanique et une hemodialyse. Deux patients sont decedes (7 %) mais presentaient respectivement 3 et 4 comorbidites pour une infection grave par le SRAS-CoV2 ; le troisieme patient, âge de 40 ans, souffrait d’hypertension et d’obesite. Les patients âges de plus de 65 ans representaient 17 % de l’ensemble de la cohorte FMF-COVID + ; 75 % ont ete hospitalises et ont eu besoin d’oxygene ; l’un d’eux est decede. Trois patients FMF-COVID + avaient une amylose AA : 2 ont ete hospitalises et un est decede. Aucun traitement anti-viral supplementaire n’a ete administre. Les 5 survivants apres hospitalisation sont rentres chez eux. Aucun d’entre eux n’a presente de signes cliniques de crise de FMF lors de l’infection par le SRAS-CoV2. Discussion Le profil des patients FMF atteints d’une forme grave ou potentiellement mortelle par le SRAS-CoV2 etait le meme que celui de la population generale. Ainsi, seuls les patients FMF presentant des facteurs de risque connus (tels que âge avance, maladie renale chronique, hypertension, maladie vasculaire, obesite et dysfonctionnement pulmonaire) ont developpe une infection grave par le SARS-CoV2 [2] . Cette etude n’est pas en faveur d’un surrisque en soi de developper une infection severe a SRAS-CoV2 en presence d’une maladie autoinflammatoire monogenique touchant un inflammasome. Aucune conclusion formelle ne peut etre tiree sur l’effet preventif de la colchicinotherapie au long cours, bien que ce travail retrospectif porte sur une large cohorte de patients traites par colchicine depuis plusieurs annees. Il est difficile de conclure a l’efficacite du traitement par inhibiteur d’IL1 vis-a-vis l’infection par le SRAS-CoV-2 chez les patients FMF, mais 50 % des patients traites au long cours sont decedes mais avaient plusieurs comorbidites ; et des publications recentes semblent plaider en faveur de l’efficacite de l’anakinra dans l’infection grave par le SRAS-CoV-2 [3] . Conclusion La FMF ne semble pas constituer un facteur de risque de developper une forme severe d’infection par SARS-CoV2 chez les patients traites au long cours par de la colchicine quotidienne, par rapport a la population generale.

Aligned ZnO nanowires (NWs) were obtained by hydrothermal method using annealed ZnO film as seed layer.Besides Si(400), only ZnO(002) diffraction peak was observed in X-ray diffraction(XRD) pattern. The lasing emissions were observed in optically pumped aligned ZnO NWs. Multi-mode emission peaks emerged when the excitation power density exceed the threshold.The integrated intensity of the spectra increases nonlinearly with the excitation power density, and the transition point from the spontaneous emission to lasing at about 96 kW/cm2 can be clearly observed.

Results: Survey results revealed that one hundred percent (100%) of attending clinicians agreed that the information presentedwas relevant and that iPad usage could be integrated into their daily work routine. One hundred percent (100%) of attending clinicians also agreed that usage of iPadswas applicable to their specific professional role. Self-assessments by the students and the instructor assessment implied that students understood cognitive learning theories and how the theories can be applied to educational technology. Conclusion(s): This project provided students with a foundational knowledge of cognitive learning theories while providing them hands-on experience with technology. Students gained insight on the importance of using best practice when teaching with technology. The health care providers at the rehabilitation hospital received valuable resources that could be used in their daily practices. Implications: The use of mobile devices such as the iPad can be a part of physical therapy curriculum. Students can apply learning theories when using iPads to educate health care professionals. Physical therapists can usemobile devices to educate patients, quickly retrievemedical information, and improve patient outcomes.

An increasing number of health care specialties are now using tele-medicine to deliver health care. This paper reviewed the use of low bandwidth equipment (LBE) in the Neuropsychology Service at Naval Medical Center San Diego and revealed that use of LBE for assessment was cost effective. The use of LiBE not only decreased cost, but also increased access while maintaining the quality of health care delivered. Cost was decreased as the neuropsychologist interviewed patients with the LBE, avoiding unnecessary TAD/TDY costs. Using the relatively inexpensive LBE which did not need costly communication lines or expensive hardware also decreased costs. Access to neuropsychology services increased because unnecessary trips to San Diego were avoided.

- Abstract
The placement of a double-J ureteral stent enables the treatment of upper urinary tract obstruction. Despite advances, forgetting the stent favors the occurrence of calcification, leading to increased morbidity rates, lawsuits, and a financial burden on the healthcare system. This paper describes a successful pyelolithotomy for the removal of a calcified double-J ureteral stent.

- Abstract
Most of the factors involved in translation (tRNA, rRNA and proteins) are subject to post-transcriptional and post-translational modifications, which participate in the fine-tuning and tight control of ribosome and protein synthesis processes. In eukaryotes, Trm112 acts as an obligate activating platform for at least four methyltransferases (MTase) involved in the modification of 18S rRNA (Bud23), tRNA (Trm9 and Trm11) and translation termination factor eRF1 (Mtq2). Trm112 is then at a nexus between ribosome synthesis and function. Here, we present a structure-function analysis of the Trm9-Trm112 complex, which is involved in the 5-methoxycarbonylmethyluridine (mcm(5)U) modification of the tRNA anticodon wobble position and hence promotes translational fidelity. We also compare the known crystal structures of various Trm112-MTase complexes, highlighting the structural plasticity allowing Trm112 to interact through a very similar mode with its MTase partners, although those share less than 20% sequence identity., (© The Author(s) 2015.

- Abstract
Treating infections caused by multidrug-resistant Gram-negative pathogens is challenging, and there is concern regarding the toxicity of the most effective antimicrobials for Gram-negative pathogens. We hypothesized that conjugating a fatty acid moiety onto a peptide dimer could maximize the interaction with lipopolysaccharide (LPS) and facilitate the permeabilization of the LPS barrier, thereby improving potency against Gram-negative pathogens. We systematically designed a series of N-lipidated peptide dimers that are active against Gram-negative bacteria, including carbapenem-resistant Enterobacteriaceae (CRE). The optimized lipid length was 6-10 carbons. At these lipid lengths, the N-lipidated peptide dimers exhibited strong LPS permeabilization. Compound 23 exhibited synergy with select antibiotics in most of the combinations tested. 23 and 32 also displayed rapid bactericidal activity. Importantly, 23 and 32 were nonhemolytic at 10 mg/mL, with no cellular or in vivo toxicity. These characteristics suggest that these compounds can overcome the limitations of current Gram-negative-targeted antimicrobials such as polymyxin B.
