The reduction and rationalisation of antibiotics used in mastitis control is an increasingly important area of dairy herd health to consider with clients due to the outcomes of the O'Neill Report and the requirement to reduce overall usage of antibiotic in the livestock sector at a national level. There is much interest around a range of strategies to achieve a reduction in antibiotic use on farm, for example cow-side treatment decisions to not use intramammary therapy and deciding not to treat low cell count cows at drying-off. However, the key driver of a reduction in antibiotic use on farm remains strategies to reduce the rate of new clinical cases and new cell count infections on farm, and therefore avoiding the need for antibiotic treatment of infected cows. This article reviews some recent research literature around some of the areas mentioned, and seeks thoughts from panel members active in mastitis control on farm.
<p>ESA&#8217;s Aeolus satellite observations are expected to have the biggest impact for the improvement of numerical weather prediction in the Tropics. An important case relating to the predictability of tropical weather systems is the outflow of Saharan dust, its interaction with cloud microphysics and impact on the development of tropical storms over the Atlantic Ocean.</p> <p>The Joint Aeolus Tropical Atlantic Campaign (JATAC) deployed on Cabo Verde (2021/2022) and the US Virgin Islands (2021) supported the validation and preparation of the ESA missions Aeolus, EarthCARE and WIVERN, and addressed science objectives regarding the Saharan Aerosol layer, African Easterly Waves and Jet, Tropical Easterly Jet, and the Intertropical Convergence Zone, as well as their relation to the formation of convective systems, and the long-range transport of dust and its impact on air quality.</p> <p>JATAC started in July 2021 with the deployment of ground-based instruments in the frame of the ASKOS project at the Ocean Science Center Mindelo, including the eVe and PollyXT lidars, and a W-band Doppler cloud radar. By mid-August, the CPEX-AW campaign started operations from the US Virgin Islands with NASA&#8217;s DC-8 flying laboratory in the Western Tropical Atlantic and Caribbean carrying the Doppler Aerosol Wind Lidar (DAWN), Airborne Precipitation and Cloud Radar (APR-3), Water Vapor DIAL and HSRL (HALO), microwave sounder (HAMSR) and dropsondes. In September the DLR Falcon-20 aircraft, carrying the ALADIN Airborne Demonstrator (A2D) and the 2-&#181;m Doppler wind lidar, and the Safire Falcon-20, carrying the high-spectral-resolution Doppler lidar (LNG), the RASTA Doppler cloud radar, in-situ cloud and aerosol instruments, and dropsondes, were deployed to Sal in the frame of the AVATAR-T and CADDIWA projects. The Aerovizija Advantic WT-10 light aircraft with optical particle spectrometers, filter-photometers and nephelometers for in-situ aerosol characterisation was operating in close coordination with the ground-based observations in the CAVA-AW project.</p> <p>The activities continued in June 2022 when the ASKOS ground based observations were enhanced with UAV airborne in-situ aerosol measurements deployed by the Cyprus Institute, solar radiation measurements supported by PMOD/WRC, dust particle orientation measurements (WALL-E lidar), and radiosonde releases equipped with electric field-mills. NASA deployed the DC-8 aircraft all September to Sal with the 2021 payload in the framework of the CPEX-CV activity, including regular radiosonde launches. As in 2021, the Aerovizija aircraft took part with in-situ aerosol measurements during two weeks in September. JATAC was supported by dedicated numerical weather and dust simulations supporting forecasting efforts and addressing open science questions.</p> <p>Around 60 scientific flights of four aircraft, with an additional 25 UAV flights, were performed during JATAC. 23 Aeolus orbits were underflown, many of them with simultaneous observations of multiple aircraft collocated with ground-based observations. In addition, the science objectives were fully covered through the large number of flights, ground based cloud and aerosol observations, regular radiosondes and dropsondes.</p> <p>Overall, JATAC activities have resulted in a high-quality and comprehensive dataset supporting a wide range of tropical atmospheric research, the validation of Aeolus and other satellites, and have provided key reference data for the development future Earth Observation missions.</p>
6539 Background: In many instances, trials may offer the best or only therapeutic option for patients with rare findings. However, conducting clinical trials of novel therapeutics targeting rare molecular variants is challenging. Patient populations are small, distributed, and predominantly in community settings where trial access remains limited by awareness and site availability. These challenges increase costs of drug development and approval, delaying widespread patient access. Methods: Foundation Medicine deployed a trial education and access program, “Precision Enrollment,” with Ignyta (a trial sponsor) and Pharmatech (a site management organization, or SMO, enabling “Just-In-Time” clinical trials) (Wiener, JCO 2007). Infrastructure and algorithms developed at Foundation Medicine (“SmartTrials Engine”) matched sequenced patients (avg n = 800/wk) with activating NTRK, ROS1, or ALK fusions to the phase II study of Entrectinib (NCT02568267). Oncologists at Foundation Medicine, through peer-to-peer outreach, facilitated trial access by providing trial and nearest site information to treating providers of matched patients. Results: 107 treatment-eligible patients with NTRK, ROS1, or ALK fusions were matched by the SmartTrials Engine; 36 (33%) expressed interest in trial participation. One such patient with NSCLC and a CD74-ROS1 fusion was unable to participate at an open trial site due to inability to travel. The patient’s site was part of the “Just-In-Time” network, with IRB and contract pre-approval, and was activated in only 3 days. Total time from patient identification to initiation of therapy was 7 days. Conclusions: We demonstrate a novel methodology for patient matching to trials targeting rare genomic findings, including in community settings. If extended, such innovative partnerships combined with computational matching infrastructure, could improve drug development and therapeutic access.
Streptococcus pluranimalium es una bacteria descrita como causante de infección en animalesy su aislamiento es poco habitual en humanos. No se han descrito casos de peritonitispor esta bacteria, tampoco se han descrito infecciones por la misma en Panamá.Presentamos el caso de un masculino de 8 años con enfermedad renal crónica, en tratamientocon diálisis peritoneal, que ingresó por una descompensación de su balance hídrico.En liquido peritoneal presentó hallazgos compatibles con peritonitis y crecimiento deS.pluranimalium en los cultivos del mismo. El cuadro clínico se resolvió con 2 semanas detratamiento con cefotaxima+ cefalotina inicialmente intravenosa y después peritoneal.El avance de las técnicas de identificación de bacterias permite describir nuevas especiescomo causantes de infección. Al haber pocos casos reportados es difícil establecer guíassobre la sensibilidad antibiótica. El S.pluranimalium es habitualmente sensible a aminoglucosidos,vancomicina y cefalosporinas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
