Is a Mini-Screen for Fetal Alcohol Spectrum Disorder Feasible?

Open Journal of Pediatrics 2024年第4期14卷 767-781页

作者： Tyler Mueller Devin Evavold June-Yung.Kim Marilyn g. Klug.Larry Burd School of Medicine and Health Sciences University of North Dakota Grand Forks USA Department of Social Work University of North Dakota Grand Forks USA

Backg.ound: Fetal Alcohol Spectrum Disorders (FASDs) are a g.obal public health concern with lifelong.consequences for affected individuals. Recent prevalence studies sug.est FASD prevalence rates rang. from 1-5% among.school ag. children. Most people with FASD are not correctly diag.osed and inadequate screening.to identify patients with increased risk may contribute to under-diag.osis. This study developed a 10-item screening.tool for FASD and examined its feasibility. Methods: The sample consisted of 355 children who had been evaluated at an FASD clinic. Data from the 33-item Alcohol Related Neurodevelopmental Disorder Behavioral Checklist was used to develop a brief FASD screen by comparing.the chang.s in Cronbach’s alpha for different combinations of items. The validity of the brief scale was then further examined using.receiving.operating.characteristic analyses. Results: The 10-item screen demonstrated acceptable sensitivity, specificity, and accuracy to identify children at hig. risk for FASD. The percentag. correctly classified was 91.3 and the area under the receiving.operating.characteristic curve was 0.971. Conclusions: This feasibility study demonstrated that a screen for FASD consisting.of 10 items with yes or no responses can be completed in 3 - 4 minutes. The tool is brief, with a low administration burden and has acceptable epidemiolog.c performance characteristics including.accuracy. Future research should examine the performance of this tool when used in larg.r, community-based populations where screening.for FASD would be appropriate.

Improved Analytical Methods for Determination of Residues of Nitrapyrin and 6-Chloropicolinic Acid in Different Crop Matrices by Liquid Chromatog.aphy-Tandem Mass Spectrometry

引用

Journal of Ag.icultural Chemistry and Environment 2024年第3期13卷 263-281页

作者： Fabiola g. Zuno-Floriano Riza L. Reyes-Punong.ayan Matt J. Heng.l Department of Environmental Toxicolog. University of California Davis California USA

Novel analytical methods were developed for the determination of nitrapyrin and 6-chloropicolinic acid (6-CPA) residues in ag.icultural products. Nitrapyrin was extracted with hexane: toluene (1:1, v/v) and 6-CPA with 0.1 N sodium hydroxide (NaOH). For nitrapyrin, samples were cleaned with silica solid phase extraction (SPE) and for 6-CPA with C18 or carbon SPE. Analysis was performed by liquid chromatog.aphy-tandem mass spectroscopy (LC-MS/MS) with external calibration (0.010 to 0.0010 µg.mL−1 for nitrapyrin and 0.0050 to 0.00025 µg.mL−1 for 6-CPA). Recoveries for nitrapyrin and 6-CPA were 68% - 102% and 66% - 90%, respectively. Nitrapyrin was detected in celery and onion (−1) and 6-CPA in onion, mustard g.eens and lettuce (−1). Lower level method validation (LLMV) for nitrapyrin and 6-CPA was 0.020 µg.g.1 and 0.050 µg.g.1, respectively. The methods presented in this study are robust and were utilized for the reg.stration of nitrapyrin on ag.icultural commodities in the United States.

The g.eat catastrophe: causes of the Permo-Triassic marine mass extinction

引用

National Science Review 2024年第1期11卷 37-50页

作者： Paul B.Wig.all David P.g.Bond School of Earth & Environment University of Leeds School of Environmental Sciences University of Hull

The marine losses during.the Permo-Triassic mass extinction were the worst ever experienced. All g.oups were badly affected, especially among.t the benthos(e.g. brachiopods, corals, bryozoans, foraminifers,ostracods). Planktonic populations underwent a fundamental chang. with eukaryotic alg.e being.replaced by nitrog.n-fixing.bacteria, g.een-sulphur bacteria, sulphate-reducing.bacteria and prasinophytes. Detailed studies of boundary sections, especially those in South China, have resolved the crisis to a ～55 kyr interval straddling.the Permo-Triassic boundary. Many of the losses occur at the beg.nning.and end of this interval painting.a picture of a two-phase extinction. Improved knowledg. of the extinction has been supported by numerous g.ochemical studies that allow diverse proposed extinction mechanisms to be studied. A transition from oxyg.nated to anoxic-euxinic conditions is seen in most sections g.obally, althoug. the intensity and timing.shows reg.onal variability. Decreased ocean ventilation coincides with rapidly rising.temperatures and many extinction scenarios attribute the losses to both anoxia and hig. *** kill mechanisms include ocean acidification for which there is conflicting.support from g.ochemical proxies and, even less likely, siltation(burial under a massive influx of terrig.nous sediment) which lacks substantive sedimentolog.cal evidence. The ultimate driver of the catastrophic chang.s at the end of the Permian was likely Siberian Trap eruptions and their associated carbon dioxide emissions with consequences such as warming. ocean stag.ation and acidification. Volcanic winter episodes stemming.from Siberian volcanism have also been linked to the crisis, but the short-term nature of these episodes(g.evidence for rapid warming.during.the crisis makes this an unlikely cause. Finally, whilst the extinction is well studied in equatorial latitudes, a different history is found in northern Boreal latitudes
