Molecular and Physiological Characterization of Fluoroquinolone-Highly Resistant Salmonella Enteritidis Strains

This report describes the dynamics of FQ-associated mutations in the highly resistant in FQ mutants in S. Enteritidis. In addition, we characterized a deletion in the ramRA integenic region, demonstrating that this frequent mutation in the highly resistant FQ mutants provide resistance or reduce susceptibility to multiple families of antibiotics. Introduction Non-typhoidal Salmonella (NTS) is a major zoonotic pathogen worldwide (Bangtrakulnonth et al., 2004; Scallan et al., 2011). Infections caused by this pathogen have been mainly associated with gastroenteritis, an acute self-limiting intestinal infection. However, it has been shown that in different regions of the world, especially in places with high percentages of immunocompromised populations, NTS is a frequent cause of bacteremia (Graham, 2010; Reddy et al., 2010; Okoro et al., 2012), an invasive life-threatening extra intestinal infection. Once acquired, this invasive salmonellosis may result in a fatality rate of 20% (Gordon, 2008). Multidrug resistance and in particular resistance to fluoroquinolones (FQs), a potent broad-spectrum family of antibiotics used for the primary treatment of invasive salmonellosis, play a key role in the treatment failure (Pers et al., 1996; Rupali et al., 2004). Fluoroquinolones resistance in NTS can be acquired through transmissible quinolone-resistance mechanisms (Martinez-Martinez et al., 1998; Redgrave et al., 2014; Hooper and Jacoby, 2015). Transmissible quinolone-resistanc...

CONCLUSION: The new classification system demonstrated substantial interobserver and intraobserver agreement between evaluators with different levels of expertise in the management of pilon fractures. Prospective studies should be done to evaluate its prognostic value and utility in clinical practice. PMID: 31800439 [PubMed - as supplied by publisher]

Authors: Kleeman-Forsthuber LT, Dennis DA, Jennings JM Abstract Cannabis has gained widespread public advocacy since its legalization in several states with recent evidence suggesting that its self-reported use has increased in patients undergoing a primary total joint arthroplasty. The endocannabinoid system has been proposed to play a role in decreasing the inflammatory cascade and enhancing pain management. For these reasons, interest has emerged in the orthopaedic community as a potential treatment or adjunct to treatment in many musculoskeletal conditions. However, the evidence to date is scant and precludes r...

Conclusion: This is the first qualitative study to specifically explore the type of support male partners of MBU patients would like in terms of content, delivery and timing. Participants expressed the need to be involved in care decisions regarding their spouse and infant and to be offered advice from professionals. They highlighted barriers to accessing support and offered solutions to minimise those. In terms of clinical implications, we recommend a support package, which could be developed for MBUs to improve outcomes for male partners and their family.

CONCLUSIONS: Career changer medical students show a small, persistent academic lag in the first 2 years of medical school and on USMLE Step 1 scores. By USMLE Step 2 the difference disappears. Similar undergraduate grade point averages and Medical College Admission Test scores suggest that science exposure, not ability may explain these differences. An unexpected finding is the number of career changer students is not increasing proportional to the proliferation of postbaccalaureate programs in the United States. This study may benefit student advisors and residency directors, and, it is hoped, provide reassurance to caree...

This study was conducted in the ED of an academic teaching hospital in Miami, Florida. It consisted of a short in-service educational intervention on how to perform and interpret POCUS, followed by an open, prospective convenience sample study in patients with clinical suspicion of shoulder dislocation. Twenty EM residents, with no prior shoulder scanning training, participated in the study. In all of the cases, the findings of the shoulder US were compared with radiographs, which were considered the reference standard. EM residents enrolled patients, and obtained and interpreted the shoulder US images. RESULTS: Sevent...
