s: Influenza-Related Hospitalization and ED Visits in Children Less Than 5 Years: 2000-2011 By pediatrics.aappublications.org Published On :: 2014-12-08T00:06:37-08:00 Influenza represents a leading cause of morbidity and a rare cause of death in children. Annual influenza vaccination was gradually expanded to include all children ≥6 months in 2008. The impact of these recommendations on disease burden is unclear.We assessed the burden of influenza-related health care encounters in children aged 6 to 59 months from 2000 to 2011. In this ecologic exploration, influenza vaccination and influenza-related emergency department visits increased over time, whereas hospitalizations decreased. Influenza-related health care encounters were greater when A(H3N2) circulated. (Read the full article) Full Article

s: Sundeck BBQs, trivia nights, and strict hygiene rules: An inside look at the life of crews locked down on luxury superyachts By feedproxy.google.com Published On :: Sat, 09 May 2020 15:00:00 GMT Source: www.businessinsider.com - Saturday, May 09, 2020 Many superyacht crew members have been stuck on their vessels after lockdowns and travel bans were instated due to the coronavirus pandemic. We spoke to crew members who felt 'lucky' to be quarantined in such luxury digs — and grateful to still have jobs and secure wages. There is still plenty of work to be done, but workers also described trivia games, sundeck BBQs, and hot tub nights they're using to pass the time and bond with colleagues. Strict new hygiene and sanitation rules have also been put into place. Visit Business Insider's homepage for more stories . In late March, billionaire businessman David Geffen posted a shot on Instagram taken from his 452-foot superyacht Rising Sun. It was hastily deleted — but not before it had raised more than a few eyebrows and stirred discourse around the 1% and their self-isolation privilege. But it's not just the rare billionaire who is bunkering down on their yacht during the COVID-19 pandemic. Here is another group of people for whom this is a new reality: the yacht's crews. Before this crisis, there were around 80,000 people employed on pleasure craft around the globe, according to Laurence Lewis, CEO of YPI Crew, a yacht recruitment agency. As countries rushed to close their borders, ports were closed — and overnight, many found themselves unable to travel to get to or leave their yachts. For many, a superyacht sounds like the dream scenario to see out lockdown. But is it? "TherAll Related Full Article

s: Spectrum of Beta-Lactamase Inhibition by the Cyclic Boronate QPX7728, an Ultra-Broad-Spectrum Beta-lactamase Inhibitor of Serine and Metallo Beta-Lactamases: Enhancement of Activity of Multiple Antibiotics Against Isogenic Strains Expressing Single {beta} By aac.asm.org Published On :: 2020-03-30T10:04:32-07:00 QPX7728 is an ultra-broad-spectrum boronic acid beta-lactamase inhibitor with potent inhibition of key serine and metallo beta-lactamases observed in biochemical assays. Microbiological studies using characterized strains were used to provide a comprehensive characterization of the spectrum of beta-lactamase inhibition by QPX7728. The MIC of multiple IV only (ceftazidime, piperacillin, cefepime, ceftolozane and meropenem) and orally bioavailable (ceftibuten, cefpodoxime, tebipenem) antibiotics alone and in combination with QPX7728 (4 μg/ml), as well as comparator agents, were determined against the panels of laboratory strains of P. aeruginosa and K. pneumoniae expressing over 55 diverse serine and metallo beta-lactamases. QPX7728 significantly enhanced the potency of antibiotics against the strains expressing Class A extended spectrum beta-lactamases (CTX-M, SHV, TEM, VEB, PER) and carbapenemases (KPC, SME, NMC-A, BKC-1), consistent with beta-lactamase inhibition demonstrated in biochemical assays. It also inhibits both plasmidic (CMY, FOX, MIR, DHA) and chromosomally encoded (P99, PDC, ADC) Class C beta-lactamases and Class D enzymes including carbapenemases such as OXA-48 from Enterobacteriaceae and OXA enzymes from Acinetobacter baumannii (OXA-23/24/72/58). QPX7728 is also a potent inhibitor of many class B metallo beta-lactamases (NDM, VIM, CcrA1, IMP, GIM but not SPM or L1). Addition of QPX7728 (4 μg/ml) reduced the MICs in a majority of strains to the level observed for the vector alone control, indicative of complete beta-lactamase inhibition. The ultra-broad-spectrum beta-lactamase inhibition profile makes QPX7728 a viable candidate for further development. Full Article
s: Imipenem population pharmacokinetics: therapeutic drug monitoring data collected in critically ill patients with or without extracorporeal membrane oxygenation [Pharmacology] By aac.asm.org Published On :: 2020-04-06T08:49:26-07:00 Carbapenem pharmacokinetic profiles are significantly changed in critically ill patients because of the drastic variability of the patients' physiological parameters. Published population PK studies have mainly focused on specific diseases and the majority of these studies had small sample sizes. The aim of this study was to develop a population PK model of imipenem in critically ill patients that estimated the influence of various clinical and biological covariates and the use of Extracorporeal Membrane Oxygenation (ECMO) and Continuous Renal Replacement Therapy (CRRT). A two-compartment population PK model with Creatinine clearance (CrCL), body weight (WT), and ECMO as fixed effects was developed using the non-linear mixed effect model (NONMEM). A Monte Carlo simulation was performed to evaluate various dosing schemes and different levels of covariates based on the pharmacokinetic/pharmacodynamic index (f%T>MIC) for the range of clinically relevant minimum inhibitory concentrations(MICs). The results showed that there may be insufficient drug use in the clinical routine drug dose regimen, and 750mg Q6h could achieve a higher treatment success rate. The blood concentrations of imipenem in ECMO patients were lower than that of non-ECMO patients, therefore dosage may need to be increased. The dosage may need adjustment for patients with CrCL ≤ 70ml/min, but dose should be lowered carefully to avoid the insufficient drug exposure. Dose adjustment is not necessary for patients within the WT ranging from 50-80 kg. Due to the large variation in PK profile of imipenem in critically ill patients, TDM should be carried out to optimize drug regimens. Full Article
s: Population pharmacokinetics of piperacillin following continuous infusion in critically ill patients: Impact of renal function on target attainment [Clinical Therapeutics] By aac.asm.org Published On :: 2020-04-13T08:15:30-07:00 Pharmacokinetic changes are often seen in patients with severe infections. Administration by continuous infusion has been suggested to optimize antibiotic exposure and pharmacokinetic/pharmacodynamic (PK/PD) target attainment for β-lactams. In an observational study, unbound piperacillin concentrations (n=196) were assessed in 78 critically ill patients following continuous infusion of piperacillin/tazobactam (ratio 8:1). The initial dose of 8, 12 or 16 g (piperacillin component) was determined by individual creatinine clearance (CRCL). Piperacillin concentrations were compared to the EUCAST clinical breakpoint MIC for Pseudomonas aeruginosa (16 mg/L), and the following PK/PD targets were evaluated: 100% fT>1xMIC and 100% fT>4xMIC. A population pharmacokinetic model was developed using NONMEM 7.4.3 consisting of a one-compartment disposition model with linear elimination separated into non-renal and renal (linearly increasing with patient CRCL) clearances. Target attainment was predicted and visualized for all individuals based on the utilized CRCL dosing algorithm. The target of 100% fT>1xMIC was achieved for all patients based on the administered dose, but few patients achieved the target of 100% fT>4xMIC. Probability of target attainment for a simulated cohort of patients showed, that increasing the daily dose by 4 g increments (piperacillin component) did not result in substantially improved target attainment for the 100% fT>4xMIC target. To conclude, in patients with high CRCL combined with high-MIC bacterial infections, even a CI regimen with a daily dose of 24 g may be insufficient to achieve therapeutic concentrations. Full Article
