A Modest E-Media Use profile characterized most children in the sample (70%). Fewer children were characterized by a High Educational Games profile (14%) or a High Adult TV/Elevated Entertainment Games Use and Background TV profile (16%). CONCLUSIONS Collectively, the three profiles reflect heterogeneous use patterns with regard to platform interaction potential and educational quality during the course of a typical week. Additional research is warranted to assess linkages between e-media use profiles and indicators of school readiness in cognitive, academic, and social and behavioral domains in diverse, low-income samples. selleck compound BACKGROUND Although higher education and healthier practices are positively associated, the explanatory mechanisms for this association remain unclear. The purpose of this study was to better understand mechanisms underlying this association by examining maternal adherence to two health-promoting infant care practices supine placement and breastfeeding. METHODS We analyzed nationally representative data from the Study of Attitudes and Factors Effecting Infant Care (SAFE), which surveyed U.S. mothers after infant birth and 2 months thereafter. Using the Theory of Planned Behavior as a framework, we used structural equation models to elucidate mediational pathways from maternal education to supine infant placement or any breastfeeding. RESULTS Data from 3297 mothers demonstrated 77.0% of infants usually were placed supine, and 57.8% received any breastfeeding. The overall direct effect of maternal educational level on supine placement and any breastfeeding was OR 1.31 (95%CI 1.11-1.54) and OR 2.82 (95%CI 2.35-3.37), respectively. In pathway analyses, the strongest associations with both supine position and breastfeeding were seen with positive attitudes (supine aOR 18.96, 95%CI 9.00-39.92; breastfeeding aOR 3.86, 95%CI 2.19-6.82) and positive social norms (supine aOR 6.69, 95%CI 4.52-9.89; breastfeeding aOR 5.17, 95%CI 4.28-6.23). Mothers with more education had higher odds of both positive attitudes and positive norms for the two practices. CONCLUSIONS The associations linking educational attainment with health practices are intricate, with multiple mediating pathways. Attitudes and social norms are powerful forces that mediate the association between maternal educational attainment and both infant supine positioning and breastfeeding, and may be important mediators for other health behaviors. Antimicrobial resistance poses a significant threat to our ability to treat infections. Especially concerning is the emergence of carbapenem-resistant Enterobacteriaceae (CRE). In the new 2019 United States Centers for Disease Control and Prevention Antibiotic Resistance Report, CRE remain in the most urgent antimicrobial resistance threat category. There is good reason for this concerning designation. In particular, the combination of several resistance elements in CRE can make these pathogens untreatable or effectively untreatable with our current armamentarium of anti-infective agents. This article reviews recently approved agents with activity against CRE and a range of modalities in the pipeline, from early academic investigation to those in clinical trials, with a focus on structural aspects of new antibiotics. Another article in this series addresses the need to incentive pharmaceutical companies to invest in CRE antimicrobial development and to encourage hospitals to make these agents available in their formularies. This article will also consider the need for change in requirements for antimicrobial susceptibility testing implementation in clinical laboratories to address practical roadblocks that impede our efforts to provide even existing CRE antibiotics to our patients. One of the primary barriers in treating cancer patients is the development of resistance to the available treatments. This is the case for treatment of triple negative breast cancer (TNBC) with docetaxel, which is part of the neoadjuvant treatment for TNBC. The novel compound SCO-101 is under investigation for its potential treatment effect in several types of drug resistant cancer. The aim of this study was to establish a pharmacodynamic model that captures the effect of docetaxel, SCO-101, and the combination on cell survival in docetaxel resistant MDA-MB-231 TNBC cells. Several combination models were compared and a recently published combination model, the general pharmacodynamic interaction model (GPDI), provided the best fit. The model allowed for description and quantification of the interaction between docetaxel and SCO-101 with respects to both maximal effect and potency. Based on this model, SCO-101 has a synergistic effect with docetaxel. This synergy is not present in the maximal effect, but the combination of SCO-101 and docetaxel showed an approximately 60% increase in potency compared to docetaxel alone. Furthermore, the predicted model surface for the combination provided key information regarding promising dose ratios and dose levels for further studies of the combination. Lastly, the study presents a use case for the GPDI model, which provides a way to quantify and interpret drug-drug interactions. V.Intrauterine adhesion (IUA) is characterized by endometrial stromal replaced with fibrous tissue during the trauma or operation induced injury. Current clinic IUA management mainly involves surgical removal of the connective tissues and physical separation and often results in reoccurrence. It is of clinic interest to directly address the issue via facilitating the endometrial repair and thereby inhibiting the formation of re-adhesion. To this end, we designed a nanocomposite aloe/poloxamer hydrogel for β-estradiol (E2) intrauterine delivery to exert multi-therapeutic effects and promote endometrial regeneration for IUA treatment. Nanoparticulate decellularized uterus (uECMNPs) was prepared to encapsulate E2 (E2@uECMNPs), which improved the solubility and prolonged cargo release. Then, E2@uECMNPs were further embedded into the thermosensitive aloe-poloxamer hydrogel (E2@uECMNPs/AP). Multiple components from E2@uECMNPs/AP system could collectively promote proliferation and inhibit apoptosis of endometrial stromal cells. E2@uECMNPs/AP significantly increased morphological recovery and decreased uterine fibrosis rate compared with IUA rats in other groups in vivo. Additionally, the levels of Ki67, cytokeratin, and estrogen receptor β were all up-regulated, along with the decreased expression of TGF-β1 and TNF-α in the uterus from rats receiving E2@uECMNPs/AP therapy. Taken together, in situ administration of E2@uECMNPs/AP hydrogel could effectively promote endometrial regeneration and prevent the re-adhesion. Exposure to complex chemical mixtures requires a tiered strategy for efficient mixture risk assessment. As a part of the EuroMix project we developed an adverse outcome pathway (AOP)-based assay toolbox to investigate the combined effects of the liver steatosis-inducing compounds imazalil, thiacloprid, and clothianidin in human HepaRG hepatocarcinoma cells. Compound-specific relative potency factors were determined using a benchmark dose approach. Equipotent mixtures were tested for nuclear receptor activation, gene and protein expression, and triglyceride accumulation, according to the molecular initiating events and key events proposed in the steatosis AOP. All three compounds affected the activity of nuclear receptors, but not key genes/proteins as proposed. Triglyceride accumulation was observed with three different methods. Mixture effects were in agreement with the assumption of dose additivity for all the combinations and endpoints tested. Compound-specific RPFs remained similar over the different endpoints studied downstream the AOP. Therefore, it might be possible to reduce testing to a smaller battery of key tests. The results demonstrate the suitability of our in vitro assay toolbox, integrated within an AOP framework and combined with the RPF approach, for the analysis of steatotic effects of chemical mixtures. However, mRNA results suggest that the steatosis AOP still needs improvement. The coronavirus disease-2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 that has significant implications for the cardiovascular care of patients. First, those with COVID-19 and preexisting cardiovascular disease (CVD) have an increased risk of severe disease and death. Second, infection has been associated with multiple direct and indirect cardiovascular complications including acute myocardial injury, myocarditis, arrhythmias and venous thromboembolism. Third, therapies under investigation for COVID-19 may have cardiovascular side effects. Fourth, the response to COVID-19 can compromise the rapid triage of non-COVID-19 patients with cardiovascular conditions. Finally, the provision of cardiovascular care may place health care workers in a position of vulnerability as they become host or vectors of virus transmission. We hereby review the peer-reviewed and preprint literature pertaining to cardiovascular considerations related to COVID-19 and highlight gaps in knowledge that require further study pertinent to patients, health care workers, and health systems. Auriculocondylar syndrome (ARCND, MIM #614669, #602483, and #615706); also known as question-mark ear syndrome or dysgnathia complex, is a rare craniofacial malformation of first and second branchial arches with a prevalence of Ap.(Arg621His)). This report increases the number of molecularly characterized ARCND patients to 29 and emphasizes the highly variable clinical presentation within families. A chronic infection caused by Toxoplasma gondii was considered asymptomatic in immunologically healthy humans, but results from animal and epidemiological studies led to a reconsideration of this assumption. The objective of this study was to evaluate the seroprevalence of T. gondii infection and its possible effects on the behavior of school-aged children in Bahia, Brazil. Serum anti-body determinations were performed by Enzyme-linked Immunosorbent Assay (ELISA). Blood lead levels (BLL) were measured by graphite furnace atomic absorption spectrometry (GFAAS). The evaluation of a child's behavior was assessed using the Child Behavior Check List (CBCL). Multivariate models applying logistic regression were used to test the association of chronic T. gondii infection and BLL with behavioral outcomes in children. Seroprevalence for anti-T.gondii IgG antibody was 43.7 % (95 %-CI 35.8-51.9). Significant associations between chronic T. gondii infection and total behavioral problems (OR = 2.50; 95 %-CI 1.06-5.88), internalizing spectrum problems (OR = 4.35; 95 %-CI 1.11-17.14) and rule breaking (OR = 2.61; 95 %-CI 1.12-6.05) were observed. A possible interaction between toxoplasmosis prevalence and lead exposure was detected. Children with above the median BLL and positive for IgG anti-T.gondii showed a 5.51-fold increase (95 %-CI 1.75-17.38) in the chance of displaying disobedient behavior. The results suggest that T. gondii infection may be contributing to the high indices of behavioral changes. Moreover, these findings are the first evidence for a possible interaction between chronic T. gondii infection and elevated blood lead levels on children's neurobehavior.
