CYP450 enzymes are involved in biotransformation of chloroquine (CQ), but the role of the different metabolism profiles of this drug has not been properly investigated in relation to P. vivax recurrences. To investigate the influence of CYPs genotypes associated with CQ-metabolism on early recurrence rates of P. vivax, a case-control study was carried out. Cases included patients presenting an early recurrence (CQ-recurrent), defined as recurrence during the first 28 days after initial infection, plasma concentrations of CQ plus desethylchloroquine (DCQ, the major CQ metabolite) higher than 100 ng/mL. A control (CQ-responsive) with no parasite recurrence over the follow-up was also included. CQ and DCQ plasma levels were measured on Day 28. CQ CYPs (CYP2C8, CYP3A4 and CYP3A5) genotypes were determined by real-time PCR. An ex vivo study was conducted to verify CQ and DCQ efficacy in P. vivax isolates. The frequency of alleles associated with normal and slow metabolism was similar between the cases and controls for CYP2C8 (OR=1.45, 95% CI=0.51-4.14, p=0.570), CYP3A4 (OR=2.38, 95% CI=0.92-6.19, p=0.105) and CYP3A5 (OR=4.17, 95% CI=0.79-22.04, p=1.038) genes. DCQ levels were higher than CQ, regardless of the genotype. Regarding the DCQ/CQ rate, there was no difference between groups or between those patients who had a normal or mutant genotype. DCQ and CQ showed similar efficacy ex vivo. CYPs genotypes had no influence on early recurrence rates. Similar efficacy of CQ and DCQ ex vivo could explain the absence of therapeutic failure, despite presence of alleles associated with slow metabolism.

The off-label use of third generation cephalosporin (3GC) during in ovo vaccination or vaccination of newly hatched chicks, was a common practice worldwide. CMY-2-producing Escherichia coli have been disseminated among broiler production. The objectives of this study were to determine the epidemiological linkage of bla_CMY-2-positive plasmids among broilers both within and outside Japan because grandparent stock and parent stock were imported in Japan. We examined the whole genome sequences of 132 3GC-resistant E. coli isolates collected from healthy broilers during 2002-2014. The predominant 3GC-resistance gene was bla_CMY-2, which was detected in the plasmids of 87 (65.9%) isolates. The main plasmid replicon types were IncI1-I (n=21; 24.1%), IncI (n=12; 13.8%), IncB/O/K/Z (n=28; 32.2%), and IncC (n=22; 25.3%). Those plasmids were subjected to gene clustering and network analyses and plasmid multi-locus sequence typing (pMLST). The chromosomal DNA of isolates was subjected to MLST and single nucleotide variant (SNV)-based phylogenetic analysis.

MLST and SNV-based phylogenetic analysis revealed high diversity of E. coli isolates. ST429 harboring bla_CMY-2-positive IncB/O/K/Z was closely related to isolates from broiler in Germany harboring bla_CMY-2-positive IncB/O/K/Z. pST55-IncI and pST12-IncI1-I and pST3-IncC were prevalent in western Japan. pST12-IncI1-I and pST3-IncC were closely related to those detected in E. coli isolates from chicken in American continent, whereas 26 IncB/O/K/Z were related to those in Europe. These data will be useful to reveal the whole picture of transmission of CMY-2-producing bacteria in and out of Japan.

Cyclophilins play a key role in the lifecycle of coronaviruses. Alisporivir (Debio 025) is a non-immunosuppressive analogue of cyclosporin A with potent cyclophilin inhibition properties. Alisporivir reduced SARS-CoV-2 RNA production in a dose-dependent manner in VeroE6 cell line, with an EC₅₀ of 0.46±0.04 μM. Alisporivir inhibited a post-entry step of the SARS-CoV-2 lifecycle. These results justify that a proof-of-concept Phase 2 trial be rapidly conducted with alisporivir in patients with SARS-CoV-2 infection.

Around the world, education is the largest recipient of philanthropic giving by a large margin, but in the United States, funders are moving away from investing in K-12 schools in favor of early childhood and higher education.

BACKGROUND:

Orphan drug development is crucial for children, who are disproportionately affected by rare diseases. Data are lacking on the number, nature, and benefit of recently approved pediatric orphan indications.

BACKGROUND:

Current guidelines from the American Academy of Pediatrics recommend screening children for developmental problems by using a standardized screening tool and referring at-risk patients to early intervention (EI) or subspecialists. Adoption of guidelines has been gradual, with research showing many children still not being screened and referred.

BACKGROUND:

Pediatricians are less frequently sued than other physicians. When suits are successful, however, the average payout is higher. Little is known about changes in the risk of litigation over time. We sought to characterize malpractice lawsuit trends for pediatricians over time.
