This study analyzed the pathogen distribution in bloodstream-infected (BSI) children hospitalized in Shandong Province from 2015 to 2018, to identify prevention strategies and select empiric antimicrobial therapy for BSI in children. Blood sample data from 14 107 children from 162 hospitals of Shandong Province were obtained from the China Antimicrobial Resistance Surveillance System and analyzed with WHONET 5.6 software. read more The results of the blood culture test showed the growth of 70.6% Gram-positive and 29.4% Gram-negative bacteria. Of the 14 107 blood isolates, 59.3% were collected from males and 40.7% were from females. Coagulase-negative staphylococci (47.1%) were the most commonly distributed pathogens. The distribution of pathogens varied according to age group and season. All Staphylococcus isolates were susceptible to vancomycin, teicoplanin and linezolid. Clinically, significant declines in penicillin-resistant Streptococcus pneumonia and carbapenem-resistant Escherichia coli were observed during the study period; however, detection rates of carbapenem-resistant Klebsiella pneumoniae increased over time (p  less then  0.05). Empiric antimicrobial therapy should be prescribed according to corresponding regional pediatric antimicrobial-resistant data.

The optimal treatment regimen for correcting 25-hydroxyvitamin D (25OHD) deficiency in children with chronic kidney disease (CKD) is not known. We compared cholecalciferol dosing regimens for achieving and maintaining 25OHD concentrations ≥30ng/ml in children with CKD stages 2-4.

An open-label multicenter randomized controlled trial randomized children with 25OHD concentrations<30ng/ml in 111 to oral cholecalciferol 3,000 IU daily, 25,000 IU weekly, or 100,000 IU monthly for 3-months (maximum 3 intensive courses).In those with 25OHD ≥30ng/ml 1,000IU cholecalciferol daily (maintenance course) was given for up to 9 months. Primary outcome was achieving 25OHD≥30 ng/ml at end of intensive phase treatment.

90 children were randomized to daily(n = 30), weekly(n = 29) or monthly(n = 31) treatment groups. At end of intensive phase, 70/90(77.8%) achieved 25OHD ≥30ng/ml; 25OHD concentrations were comparable between groups (median 44.3, 39.4, and 39.3 ng/ml for daily, weekly, and monthly groups respectively; p ren with glomerular disease required higher doses of cholecalciferol compared to those with non-glomerular disease.The development of plant model organisms has traditionally been analyzed using resource-heavy, tailored applications that are not easily transferable to distantly related non-model taxa. Thus, our understanding of plant development has been limited to a subset of traits, and evolutionary studies conducted most effectively either across very wide [e.g. Arabidopsis thaliana and Oryza sativa (rice)] or narrow (i.e. population level) phylogenetic distances. As plant biologists seek to capitalize on natural diversity for crop improvement, enhance ecosystem functioning, and better understand plant responses to climate change, high-throughput and broadly applicable forms of existing molecular biology assays are becoming an invaluable resource. Next-generation sequencing (NGS) is increasingly becoming a powerful tool in evolutionary developmental biology (evo-devo) studies, particularly through its application to understanding trait evolution at different levels of gene regulation. Here, I review some of the most common and emerging NGS-based methods, using exemplar studies in reproductive plant evo-devo to illustrate their potential.Organophosphate esters (OPEs) are used widely as flame retardants and plasticizers but much remains unknown about their potential toxicity. Previously, we reported that 4 individual OPEs suppress endochondral ossification in murine limb bud cultures. However, real-life exposure is to complex OPE mixtures. In the present study, we tested the hypothesis that a Canadian household dust-based OPE mixture will affect endochondral ossification in gestation day 13 CD1 mouse embryo limb buds expressing fluorescent markers for the major cell populations involved in the process collagen type II alpha 1-enhanced cyan fluorescent protein (proliferative chondrocytes), collagen type X alpha 1-mCherry (hypertrophic chondrocytes), and collagen type I alpha 1-yellow fluorescent protein (osteoblasts). Limbs were cultured for 6 days in the presence of vehicle or dilutions of the OPE mixture (1/1 000 000, 1/600 000, and 1/300 000). All 3 OPE mixture dilutions affected cartilage template development and the progression of endochondral ossification, as indicated by the fluorescent markers. The expression of Sox9, the master regulator of chondrogenesis, was unchanged, but the expression of Runx2 and Sp7, which drive chondrocyte hypertrophy and osteoblastogenesis, was dilution-dependently suppressed. RNA-seq revealed that exposure to the 1/300 000 dilution of the OPE mixture for 24 h downregulated 153 transcripts and upregulated 48 others by at least 1.5-fold. Downregulated transcripts were enriched for those related to the immune system and bone formation. In contrast, upregulated transcripts were enriched for those with stress response functions known to be regulated by ATF4 activation. Thus, exposure to the mixture of OPEs commonly found in house dust may have adverse effects on bone formation.

Can the Endometriosis Fertility Index (EFI) be estimated accurately before surgery?

The EFI can be estimated accurately based on mere clinical/ultrasound information, with some improvement after adding data from diagnostic laparoscopy.

The EFI is a validated clinical instrument predicting the probability of pregnancy after endometriosis surgery without the use of ART. Being an end-of-surgery-score, it implies the decision for operative laparoscopy to be made in advance-hence, its role in the pre-surgical decision-making process remains to be established.

Single-cohort prospective observational study in 82 patients undergoing complete endometriosis excision (between June and December 2016). Two methods were used to estimate the final EFI type A based on non-surgical clinical/ultrasound findings only, and type B based on the combination of non-surgical clinical/ultrasound findings and diagnostic laparoscopy data. To calculate EFI type A, an algorithm was created to translate non-surgical clinical/imaginSA. This work was initiated before he joined Merck KGaA in October 2015, and completed during the subsequent years.

Chronic infection and inflammatory disorders as well as immunodeficiencies are often associated with decline and/or dysfunction of MAIT cells. Herein, we investigate the MAIT cells in patients with idiopathic CD4 + lymphocytopenia (ICL), a syndrome characterized by consistently low CD4 T-cell counts ( less then 300 cell/µL) in the absence of HIV infection or other known immunodeficiency, and by susceptibility to certain opportunistic infections. The numbers, phenotype and function of MAIT cells in peripheral blood were preserved in ICL patients compared to healthy controls. Furthermore, administration of IL-7 to ICL patients expanded the CD8 + MAIT cell subset, with maintained responsiveness and effector functions after IL-7 treatment. In conclusion, ICL patients maintain normal levels and function of MAIT cells preserving some antibacterial responses despite the deficiency in CD4 + T cells.

Concern has been raised in the rheumatology community regarding recent regulatory warnings that HCQ used in the coronavirus disease 2019 pandemic could cause acute psychiatric events. We aimed to study whether there is risk of incident depression, suicidal ideation or psychosis associated with HCQ as used for RA.

We performed a new-user cohort study using claims and electronic medical records from 10 sources and 3 countries (Germany, UK and USA). RA patients ≥18 years of age and initiating HCQ were compared with those initiating SSZ (active comparator) and followed up in the short (30 days) and long term (on treatment). Study outcomes included depression, suicide/suicidal ideation and hospitalization for psychosis. Propensity score stratification and calibration using negative control outcomes were used to address confounding. Cox models were fitted to estimate database-specific calibrated hazard ratios (HRs), with estimates pooled where I2 <40%.

A total of 918 144 and 290 383 users of HCQ and SSZ, rAS (reference no. EUPAS34497; http//www.encepp.eu/encepp/viewResource.htm? id=34498).

We tested the hypothesis that alterations of sleep, rest-activity, and light exposure patterns are associated with worse cognition in cirrhosis. 54 ambulatory adult patients with cirrhosis and 41 age/gender-matched healthy controls wore wrist actigraphy for rest-activity and light measurements and completed PROMIS sleep instruments for self-reported sleep quality. We used standard nonparametric descriptors to characterize rest-activity and light patterns, and wake after sleep onset and sleep efficiency to assess objective sleep quality. The NIH Toolbox cognition battery was used for objective cognitive evaluation using T-scores from a demographically-adjusted population reference. Spearman's correlation and multivariable models were used to explore associations between measures of cognition, sleep, rest-activity, and light. Cognition was significantly impaired in cirrhosis patients. Sleep quality was worse in cirrhosis patients by subjective and objective measures compared to controls. Cirrhosis patients exhibited fragmented and dampened rest-activity rhythms, lower daytime and higher nighttime light exposure compared to controls. Worse working memory and processing speed was associated with lower daytime activity level, higher rest-activity fragmentation, lower day-to-day stability, and greater nocturnal light exposure. No association was found between cognition and sleep quality. Rest-activity fragmentation and abnormal light exposure patterns are common in patients with liver disease and are associated with the severity of cognitive impairment. Further research is needed to investigate the effects of timed bright light and exercise intervention on cognitive function in patients with liver disease.

Bisphosphonates are administered to post-transplantation patients with mineral and bone disorders; however, the association between bisphosphonate therapy and long-term renal graft survival remains unclear.

This nested case-control study investigated the effects of bisphosphonates on long-term graft outcomes after kidney transplantation. We enrolled 3836 kidney transplant recipients treated from April 1979 to June 2016 and matched patients with graft failure to those without (controls). Annual post-transplant bone mineral density assessments were performed and recipients with osteopenia or osteoporosis received bisphosphonate therapy. The associations between bisphosphonate use and long-term graft outcomes and graft survival were analyzed using conditional logistic regression and landmark analyses, respectively.

A landmark analysis demonstrated that death-censored graft survival was significantly higher in bisphosphonate users than in non-users in the entire cohort (log-rank test, P < 0.001). In the nested case-control matched cohort, bisphosphonate users had a significantly reduced risk of graft failure than did non-users (odds ratio = 0.
