BackgroundIn 2017, approximately 73% of antibiotics in England were prescribed from primary care practices. It has been estimated that 9%–23% of antibiotic prescriptions between 2013 and 2015 were inappropriate. Reducing antibiotic prescribing in primary care was included as one of the national priorities in a financial incentive scheme in 2015–2016.AimTo investigate whether the effects of the Quality Premium (QP), which provided performance-related financial incentives to clinical commissioning groups (CCGs), could be explained by practice characteristics that contribute to variations in antibiotic prescribing.Design & settingLongitudinal monthly prescribing data were analysed for 6251 primary care practices in England from April 2014 to March 2016.MethodLinear generalised estimating equations models were fitted, examining the effect of the 2015–2016 QP on the number of antibiotic items per specific therapeutic group age–sex related prescribing unit (STAR-PU) prescribed, adjusting for seasonality and months since implementation. Consistency of effects after further adjustment for variations in practice characteristics were also examined, including practice workforce, comorbidities prevalence, prescribing rates of non-antibiotic drugs, and deprivation.ResultsAntibiotics prescribed in primary care practices in England reduced by -0.172 items per STAR-PU (95% confidence interval [CI] = -0.180 to -0.171) after 2015–2016 QP implementation, with slight increases in the months following April 2015 (+0.014 items per STAR-PU; 95% CI = +0.013 to +0.014). Adjusting the model for practice characteristics, the immediate and month-on-month effects following implementation remained consistent, with slight attenuation in immediate reduction from -0.172 to -0.166 items per STAR-PU. In subgroup analysis, the QP effect was significantly greater among the top 20% prescribing practices (interaction p<0.001). Practices with low workforce and those with higher diabetes prevalence had greater reductions in prescribing following 2015–2016 QP compared with other practices (interaction p<0.001).ConclusionIn high-prescribing practices, those with low workforce and high diabetes prevalence had more reduction following the QP compared with other practices, highlighting the need for targeted support of these practices and appropriate resourcing of primary care.

Summary. Objective — increasing the efficiency of diagnosis and treatment in patients with destructive forms of pancreatitis.
Materials and methods. 89 patients with acute destructive pancreatitis were examined. There were 37 men (41,5 %), 52 women (58,4 %). The average age of patients ranged from 28 to 64 years. In order to objectively assess the severity of the inflammatory process in the pancreas and surrounding tissues, organs of the abdominal cavity, clinical and biochemical studies were used, as well as high-tech methods such as ultrasound examination with dopplerometry, computed tomography.
Results. According to ultrasound, the edematous form of acute pancreatitis was diagnosed in 22 (27,4 %) patients during the examination, fatty pancreatic necrosis was diagnosed in 19 (21,3 %) patients. Hemorrhagic pancreatic necrosis was found in 31 (34,8 %) patients, mixed in 17 (19,1 %) patients. The study revealed the main etiological factors of the disease, while in 63 (70,8 %) patients the cause of acute pancreatitis was biliary pathology, alcohol etiology occurred in 17 (19,1 %) patients, and 9 (10,1 %)) - she had a post-traumatic character. Computed tomography was performed in cases of doubt in the data of ultrasound examination, especially in patients with overweight, and for the purpose of differential diagnosis in 23 (25,8 %) patients.
Conclusions. Acute destructive forms of pancreatitis have a polymorphic echography picture. Ultrasound diagnostics and computed tomography should be mandatory elements of the diagnostic algorithm for various forms of acute destructive pancreatitis. The diagnostic accuracy of these non-invasive methods in verification of acute destructive pancreatitis and its complications as a whole was 92,8 %. A decrease in the level of postoperative complications and mortality associated with a decrease in the progression of pancreatic necrosis because of suppression of pancreatic secretion.

Adaptation de la formation en communication aux nouveaux métiers
Authors: EL MENDILI Soumaya 
Published: July 2020

Un des problèmes qui se pose actuellement dans nos formations universitaires est la non adaptation des contenus aux besoins du marché de l'emploi. Les conséquences de ce problême se résument comme suit : « Des universités qui ne répondent pas aux besoins du marché de l'emploi », « Des étudiants perdant leurs temps dans des filiêres qui ne correspondent pas a leur attentes » et « Des entreprises qui ne trouvent pas des profils adaptés a leurs besoins », etc. De ce fait nous allons nous retrouvés avec des nouveaux diplômés ne possédant forcement pas toutes les compétences, les connaissances et les qualités personnelles dont les entreprises ont besoin.
Ce problême est rendu encore plus difficile par l'évolution des métiers surtout dans l'univers de la communication avec l'apparition des technologies de l'information et de la communication, puisque des nouveaux besoins se découvrent au fil du temps. Par conséquent « comment nous pourrons définir le contour des métiers dans le domaine de la communication avec l'apparition de nouvelles exigences et nouveaux besoins ? ».
Toutes ces réflexions nous poussent à dire que les deux institutions « université » et « entreprise » doivent être fortement liées et que les entreprises qui sont engagées dans l'activité doivent participer eux-mêmes à sa réalisation.
D'où la nécessite de s'adresser aux entreprises dans la phase de conception, ainsi dans la phase de l'amélioration du contenu de la formation universitaire, d'une part pour répondre aux exigences du marché de l'emploi, et d'autre part pour suivre l'évolution des métiers et l'adapter aux nouveaux besoins potentiels.
Pour répondre a ces questions, une réflexion doit être porté dans un premier lieu sur les objectifs décrites et inscrites par l'organisme de formation et dans un deuxiême temps commencer a réfléchir sur le comment c'est-à -dire les moyens a mettre en place pour prendre en considération les besoins des clients dans le programme universitaire.

Abstract
Detections of massive stars in the direction of the H ii region CS 78 in NGC 6334 and of G332.809−0.132 are here presented. The region covered by the G332.809−0.132 complex coincides with the RCW 103 stellar association. In its core (40′ in radius), approximately 110 OB candidate stars (K

s
< 10 mag and 0.4 <

< 1.6 mag) were identified using 2MASS, DENIS, and GLIMPSE data. This number of OB stars accounts for more than 50% of the observed number of Lyman continuum photons from this region. Medium-resolution K-band spectra were obtained for seven early types, including one WN 8 star and one Ofpe/WN 9 star; the latter is located near the RCW 103 remnant and its luminosity is consistent with a distance of ≈3 kpc. The area analyzed encloses 9 of the 34 OB stars previously known in RCW 103, as well as IRAS 16115−5044, which we reclassify as a candidate luminous blue variable. The line of sight is particularly interesting, crossing three spiral arms; a molecular cloud at −50 (with RCW 103 in the Scutum-Crux arm) and another at −90 km s−1 (in the Norma arm) are detected, both rich in massive stars and supernova remnants. We also report the detection of a B supergiant as the main ionizing source of CS 78, 2MASS J17213513−3532415. Medium-resolution H- and K-band spectra display H i and He i lines, as well as Fe ii lines. By assuming a distance of 1.35 kpc, we estimate a bolometric magnitude of −6.16, which is typical of supergiants.

Reproductive Characteristics and Performance of the Florida Panther: A Retrospective Examination of Long-Term Data
Authors: Bartareau Tad M. 
Published: July 2020

AbstractKnowledge of reproductive characteristics and performance (RCP) is necessary to estimate a species' breeding output and provide indicators to evaluate population health. Long-term data are important because they provide insight into the roles of intrinsic and extrinsic factors in determining RCP and lifetime breeding output of individuals and productivity of populations. Here, I examine the RCP of the Florida panther Puma concolor coryi by using an extensive data set collected from 1981 to 2019. My objective is to establish baseline RCP parameters and to determine the factors that affect lifetime breeding output. Briefly, the results from a variety of data analyses show the following: 1) Florida panthers exhibit a spring (March–May) birth pulse; 2) minimum age at sexual maturity does not differ between sexes; 3) mean annual proportion of females reproducing, litter size, and birth rate progressively decrease with increasing maternal age; 4) mean litter sex ratio is male biased; 5) mean birth interval differs between successful and unsuccessful litters; 6) proportion of kittens that recruited into the breeding population is small; and 7) distribution of parentage and mating partners among individuals in litters of known mothers and fathers is right skewed. The results indicate that breeding output is limited both by low birth rate and small proportion of offspring recruiting into the breeding population. The decreasing RCP with increasing maternal age suggests that costs of reproduction and progressive body condition senescence are important factors limiting lifetime breeding output. Despite these inhibiting factors, the data came from a period of substantial population growth and expansion since 1995, so the RCP shown is productive for this species. Outcomes from this study provide important RCP information for wildlife managers to implement measurable criteria to assess trends in Florida panther breeding output and population health.
