The role of day care for teenage mothers in a public school

Society stresses that teenage mothers should be helped to finish their high school education. However, their schooling can become a reality only if accompanied by child care.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44266/1/10566_2005_Article_BF01132194.pd

Cognitive Interview-Based Validation of the Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events in Adolescents with Cancer

Context The National Cancer Institute created the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) to allow direct input on symptomatic adverse events (AEs) from adult patients in oncology trials. Objectives This study sought to determine the youngest age to complete the PRO-CTCAE, evaluated comprehension of PRO-CTCAE among adolescents, tested new items not currently in PRO-CTCAE, and tested a parent-proxy version. Methods From seven pediatric cancer hospitals, 51 adolescents (13–20 years) receiving cancer treatment participated, along with 40 parent proxies. We evaluated 55 AEs from the PRO-CTCAE library (97 questions) and seven new AEs not in PRO-CTCAE that assess symptom frequency, severity, interference, or presence. Questions were distributed across three forms to reduce burden. Cognitive interviews with retrospective probing were completed in age groups of 13–15 and 16–20 year olds. Proxies were interviewed independently. Results In general, the 16–20 year olds and the parent proxies were able to understand and complete the PRO-CTCAE and newly designed AE questions. Five PRO-CTCAE terms (bloating of the abdomen, anxiety, flashing lights in front of your eyes, hot flashes, and bed sores) and the wording of the questions about AE severity were challenging for a few adolescents and proxies. The 13–15 year olds had greater challenges completing the PRO-CTCAE. Conclusion This study extends use of the adult PRO-CTCAE for adolescents as young as 16 years and proposes new questions for seven new symptomatic AEs and a parent-proxy version of PRO-CTCAE. Additional testing of the new questions and alternative language for more challenging PRO-CTCAE items is recommended in adults

Star clusters near and far; tracing star formation across cosmic time

© 2020 Springer-Verlag. The final publication is available at Springer via https://doi.org/10.1007/s11214-020-00690-x.Star clusters are fundamental units of stellar feedback and unique tracers of their host galactic properties. In this review, we will first focus on their constituents, i.e.\ detailed insight into their stellar populations and their surrounding ionised, warm, neutral, and molecular gas. We, then, move beyond the Local Group to review star cluster populations at various evolutionary stages, and in diverse galactic environmental conditions accessible in the local Universe. At high redshift, where conditions for cluster formation and evolution are more extreme, we are only able to observe the integrated light of a handful of objects that we believe will become globular clusters. We therefore discuss how numerical and analytical methods, informed by the observed properties of cluster populations in the local Universe, are used to develop sophisticated simulations potentially capable of disentangling the genetic map of galaxy formation and assembly that is carried by globular cluster populations.Peer reviewedFinal Accepted Versio

Systematic Review of Medicine-Related Problems in Adult Patients with Atrial Fibrillation on Direct Oral Anticoagulants

New oral anticoagulant agents continue to emerge on the market and their safety requires assessment to provide evidence of their suitability for clinical use. There-fore, we searched standard databases to summarize the English language literature on medicine-related problems (MRPs) of direct oral anticoagulants DOACs (dabigtran, rivaroxban, apixban, and edoxban) in the treatment of adults with atri-al fibrillation. Electronic databases including Medline, Embase, International Pharmaceutical Abstract (IPA), Scopus, CINAHL, the Web of Science and Cochrane were searched from 2008 through 2016 for original articles. Studies pub-lished in English reporting MRPs of DOACs in adult patients with AF were in-cluded. Seventeen studies were identified using standardized protocols, and two reviewers serially abstracted data from each article. Most articles were inconclusive on major safety end points including major bleeding. Data on major safety end points were combined with efficacy. Most studies inconsistently reported adverse drug reactions and not adverse events or medication error, and no definitions were consistent across studies. Some harmful drug effects were not assessed in studies and may have been overlooked. Little evidence is provided on MRPs of DOACs in patients with AF and, therefore, further studies are needed to establish the safety of DOACs in real-life clinical practice

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

The Influence of Age and Sex on Genetic Associations with Adult Body Size and Shape : A Large-Scale Genome-Wide Interaction Study

Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age-and/or sex-specific effects of genetic variants on BMI and WHRadjBMI, we performed meta-analyses of 114 studies (up to 320,485 individuals of European descent) with genome-wide chip and/or Metabochip data by the Genetic Investigation of Anthropometric Traits (GIANT) Consortium. Each study tested the association of up to similar to 2.8M SNPs with BMI and WHRadjBMI in four strata (men 50y, women 50y) and summary statistics were combined in stratum-specific meta-analyses. We then screened for variants that showed age-specific effects (G x AGE), sex-specific effects (G x SEX) or age-specific effects that differed between men and women (G x AGE x SEX). For BMI, we identified 15 loci (11 previously established for main effects, four novel) that showed significant (FDR= 50y). No sex-dependent effects were identified for BMI. For WHRadjBMI, we identified 44 loci (27 previously established for main effects, 17 novel) with sex-specific effects, of which 28 showed larger effects in women than in men, five showed larger effects in men than in women, and 11 showed opposite effects between sexes. No age-dependent effects were identified for WHRadjBMI. This is the first genome-wide interaction meta-analysis to report convincing evidence of age-dependent genetic effects on BMI. In addition, we confirm the sex-specificity of genetic effects on WHRadjBMI. These results may providefurther insights into the biology that underlies weight change with age or the sexually dimorphism of body shape.Peer reviewe

Using ITS2 PCR-RFLP to generate molecular markers for authentication of Sophora flavescens Ait

BACKGROUND: Dried root of Sophora flavescens Ait. is a medicinal material occasionally misused or adulterated by other species similar in appearance. In this study the internal transcribed spacer (ITS) regions of DNA samples of S. flavescens Ait. collected from different areas of Taiwan were amplified by polymerase chain reaction (PCR) and compared. The effectiveness of using ITS2 PCR restriction fragment length polymorphism (RFLP)-generated markers to differentiate S. flavescens Ait. from possible adulterants was also evaluated. BACKGROUND: Dried root of Sophora flavescens Ait. is amedicinal material occasionally misused or adulterated by other species similar in appearance. In this study the internal transcribed spacer (ITS) regions of DNA samples of S. flavescens Ait. collected from different areas of Taiwan were amplified by polymerase chain reaction (PCR) and compared. The effectiveness of using ITS2 PCR restriction fragment length polymorphism (RFLP)-generated markers to differentiate S. flavescens Ait. from possible adulterants was also evaluated. RESULTS: The S. flavescens Ait. samples collected from different areas were extremely low in ITS sequence variability at species level. ITS2 PCR-RFLP coupled with restriction enzymes Sac I, Sac II, Xho I or Pvu I produced specific fragments for all tested variants. ITS2 PCR-RFLP coupled with Sac II was further performed to identifymixtures of DNA extracts of S. flavescens Ait. and Sophora tomentosa L. in various ratios. The developed ITS2 PCR-RFLP markers could detectmixed DNA samples of S. flavescens Ait./S. tomentosa L. up to a ratio of 10 : 1. CONCLUSION: The present study demonstrates the usefulness of ITS2 PCR-RFLP coupled with pre-selected restriction enzymes for practical and accurate authentication of S. flavescens Ait. The technique is also suitable for analysing S. flavescens Ait. mixed with other adulterants. (C) 2011 Society of Chemical Industr

The synthesis, characterization of oxidized multi-walled carbon nanotubes, and application to surface acoustic wave quartz crystal gas sensor

Intermetallic alloy catalysts had been prepared by the polyol method, and used for the growth of the individual- or bundle-shaped multi-walled carbon nanotubes (MWCNTs) by thermal chemical vapor deposition method. The purified MWCNTs catalyzed by Mg(28)-Ni(68)-Mo(4) alloy catalyst were oxidized with the nitric acid/hydrogen peroxide solution (volume ratio= 2/1) to generate carboxylic acid groups. The oxidized MWCNTs (MWCNT-COOH) were further modified with different molecular weights of polyethylene glycols and chloromethyl styrene, respectively, to verify carboxylic acid groups and achieve higher hydrophobic property. Contents of organic functional groups grafted on MWCNTs were estimated with thermogravimetric analysis experiments. In addition, the MWCNT-COOH and poly (n,n-dimethylamino propylsilsesquioxane) (SXNR) were mixed in the THF solvent, and sprayed onto the surface of SAW crystal gas sensor. The MWCNT-COOH were employed to the 156 MHz surface acoustic wave (SAW) quartz crystal sensor for the adsorption of ethanol vapor. The SAW quartz crystal gas sensor coated with the MWCNT-COOH/SXNR was exhibited a high response for ethanol vapor efficiently. (C) 2007 Elsevier B.V. All rights reserved
