Statistically significant differences (p  less then  0.001) were found between observed and expected counts across all five demographic variables. Conclusions This is the first population-based study to assess the incidence rates of PPD among all active duty military servicewomen. Findings that some groups were over- and underdiagnosed within each demographic category, and that PPD incidence rates have increased between 2001 and 2018, underscore the importance of further research to inform policies and interventions supporting this vulnerable population.Purpose We investigated four theoretically based latent variable models of word learning in young school-age children. MC903 Method One hundred sixty-seven English-speaking second graders with typical development from three U.S. states participated. They completed five different tasks designed to assess children's creation, storage, retrieval, and production of the phonological and semantic representations of novel words and their ability to link those representations. The tasks encompassed the triggering and configuration stages of word learning. link2 Results Results showed that a latent variable model with separate phonological and semantic factors and linking indicators constrained to load on the phonological factor best fit the data. Discussion The structure of word learning during triggering and configuration reflects separate but related phonological and semantic factors. We did not find evidence for a unidimensional latent variable model of word learning or for separate receptive and expressive word learning factors. In future studies, it will be interesting to determine whether the structure of word learning differs during the engagement stage of word learning when phonological and semantic representations, as well as the links between them, are sufficiently strong to affect other words in the lexicon.Purpose The purpose was to examine and determine effect size distributions reported in published audiology and speech-language pathology research in order to provide researchers and clinicians with more relevant guidelines for the interpretation of potentially clinically meaningful findings. Method Cohen's d, Hedges' g, Pearson r, and sample sizes (n = 1,387) were extracted from 32 meta-analyses in journals in speech-language pathology and audiology. Percentile ranks (25th, 50th, 75th) were calculated to determine estimates for small, medium, and large effect sizes, respectively. The median sample size was also used to explore statistical power for small, medium, and large effect sizes. Results For individual differences research, effect sizes of Pearson r = .24, .41, and .64 were found. For group differences, Cohen's d/Hedges' g = 0.25, 0.55, and 0.93. These values can be interpreted as small, medium, and large effect sizes in speech-language pathology and audiology. The majority of published research was inadequately powered to detect a medium effect size. Conclusions Effect size interpretations from published research in audiology and speech-language pathology were found to be underestimated based on Cohen's (1988, 1992) guidelines. Researchers in the field should consider using Pearson r = .25, .40, and .65 and Cohen's d/Hedges' g = 0.25, 0.55, and 0.95 as small, medium, and large effect sizes, respectively, and collect larger sample sizes to ensure that both significant and nonsignificant findings are robust and replicable.Background Intravenous lidocaine infusions have been shown to be effective for cancer related pain, but access is restricted to acute care settings. If able to be shown to be safe and effective, the subcutaneous route could expand access to residential hospices or patients' homes. Objectives This randomized, double-blind, placebo controlled, 2 × 2 crossover trial evaluated the effectiveness, safety, toxicity, and impact on quality of life of a limited duration subcutaneous lidocaine infusion (SCLI) for chronic cancer pain. Methods Patients with the life expectancy of three months or more, who were experiencing cancer-related pain with a worst severity of at least 4 on a 0-10 scale despite a trial of at least one opioid and appropriate adjuvant analgesic, received two subcutaneous infusions at least a week apart; lidocaine 10 mg/kg over 5.5 hours and saline placebo. The primary outcome was either a reduction in worst pain intensity of two points out of 10 or a reduction in 24 hours opioid dose of at least 30% without worsening of pain scores, in seven days. Results The SCLI was only effective for two subjects. One of these subjects experienced a drop in worst pain score and the other experienced a reduction in opioid dose. Conclusions A weight-based subcutaneous infusion of lidocaine does not achieve sufficiently predictable blood levels for determining lidocaine responsiveness. This study does not allow any conclusion to be drawn on whether or not lidocaine would have been more effective had it been titrated to higher blood levels.Purpose The aim of this study was to investigate the ability of preschoolers with speech sound disorder (SSD) and with typical speech and language development (TD) to understand foreign-accented words, providing a window into the quality of their underlying phonological representations. We also investigated the relationship between vocabulary skills and the ability to identify words that are frequent and have few neighbors (lexically easy words) and words that are less frequent and have many neighbors (lexically hard words). Method Thirty-two monolingual English-speaking children (16 with SSD, 16 with TD), ages 4 and 5 years, completed standardized speech and language tests and a two-alternative forced-choice word identification task of English words produced by a native English speaker and a native Korean speaker. Results Children with SSD had more difficulty identifying words produced by both talkers than children with TD and showed a larger difficulty identifying Korean-accented words. Both groups of children identified lexically easy words more accurately than lexically hard words, although this difference was not significant when including receptive vocabulary skills in the analysis. Identification of lexically hard words, both those produced by the native English speaker and the nonnative English speaker, increased with vocabulary size. Conclusion Considering the performance of the children with SSD under ideal listening conditions in this study, we can assume that, as a group, children with SSD may experience greater difficulty identifying foreign-accented words in environments with background noise.Advanced nonsmall-cell lung cancer (NSCLC) patients with mutated epidermal growth factor receptor (EGFR) can remarkably benefit from target therapy of EGFR-tyrosine kinase inhibitors (TKIs). However, increasing drug sensitivity and improving outcomes of NSCLC patients to EGFR-TKI therapy remains a challenge. Several studies have shown a link between microRNAs and drug resistance in cancer. In this study, we hypothesized that the rs12740674 single nucleotide polymorphism in the enhancer of miR-1262 may affect its expression, which may impact the outcome of NSCLC patients treated with EGFR-TKIs. The rs12740674 polymorphism was genotyped in two independent cohorts, including 319 EGFR-TKI treated stage IIIB/IV NSCLC patients. The allele-specific regulation on miR-1262 transcription by rs12740674 and impacts of miR-1262 on gefitinib sensitivity were evaluated in vitro and in vivo. Cox regression analyses indicated that the rs12740674 T allele was significantly associated with short survival time in both cohorts (p  less then  0.05). Luciferase assays demonstrated that the rs12740674 T allelic enhancer showed weaker capability to promote miR-1262 transcription compared with the C allelic enhancer, which may be due to reduced transcription factor binding according to electrophoretic mobility shift assays. Furthermore, significantly decreased miR-1262 expression in NSCLC and nontumor lung tissues of T allele carriers was observed compared with levels in C allele carriers. Moreover, miR-1262 expression enhanced the anticancer effects of gefitinib on NSCLC cells. Our data indicate that miR-1262 may be a potential therapeutic target for NSCLC.The saphenous vein is the most commonly used bypass graft in patients with coronary artery disease. During routine coronary artery bypass grafting the vascular damage inflicted on the vein is likely to stimulate the release of endothelin-1, a potent endothelium-derived vasoconstrictor that also possesses cell proliferation and inflammatory properties, conditions associated with vein graft failure. In both in vitro and in vivo studies, endothelin receptor antagonists reduce neointimal thickening. The mechanisms underlying these observations are multi-factorial and include an effect on cell proliferation and cell/tissue damage. Much of the data supporting the beneficial action of endothelin-1 receptor antagonism at reducing intimal thickening and occlusion in experimental vein grafts was published over 20 years ago. The theme of the recent ET-16 conference in Kobe was "Visiting Old and Learning New". This short review article provides an overview of studies showing the potential of endothelin receptor antagonists to offer an adjuvant therapeutic approach for reducing saphenous vein graft failure and poses the question why this important area of research has not been translated from bench to bedside given the potential benefit for coronary artery bypass patients?Renal cell carcinoma (RCC) has been regarded as one of the most malignant tumor types. Chemotherapy (such as sorafenib) is used as common strategy for treating RCC. link3 To date, whether long noncoding RNA KIF9-AS1 is involved in RCC progression and drug resistance remains unknown. In this investigation, we detected gene expression levels by western blot and RT-qPCR. MTT and TUNEL experiments were used to show cell viability and apoptosis, respectively. KIF9-AS1 overexpression led to enhanced cell viability, increased IC50 value of sorafenib, and decreased apoptosis. miR-497-5p acted as key interaction factor for KIF9-AS1 in RCC. More importantly, we found that transforming growth factor-β and autophagy signaling pathways were both critical effectors for mediating KIF9-AS1/miR-497-5p axis-induced drug resistance phenotypes (cell viability, IC50, apoptosis) of RCC. In conclusion, our study revealed that KIF9-AS1 played a positive role in drug resistance of RCC cells to sorafenib, potentially driving the development of targeted diagnostic and therapeutical approaches.Bluetongue is one of the most important vector-borne viral diseases that can lead to significant economic losses as a result of reduction of productivity and even death in some susceptible ruminants. However, epidemiological information on bluetongue virus (BTV) infection in cattle and goats is scarce in China. To determine the seropositive rate and risk factors of BTV infection in cattle and goats in Guangxi province, a subtropical region in Southern China, a total of 548 cattle serum samples and 6567 goat serum samples collected from 13 cities across Guangxi province during 2003-2015 were analyzed and found that the seroprevalence is 44.5% (244/548) in cattle and 28.0% (1837/6567) in goats and the main BTV serotypes are BTV-1, -2, -4, and -8. Climatic zone, age, and species are found to be the likely risk factors for BTV infection. To our knowledge, this is the first large-scale serological survey for BTV infection in domestic cattle and goats in Guangxi province, Southern China.
