Speaker- versus listener-oriented disfluency: A re-examination of arguments and assumptions from autism spectrum disorder

We re-evaluate conclusions about disfluency production in high-functioning forms of autism spectrum disorder (HFA). Previous studies examined individuals with HFA to address a theoretical question regarding speaker- and listener-oriented disfluencies. Individuals with HFA tend to be self-centric and have poor pragmatic language skills, and should be less likely to produce listener-oriented disfluency. However, previous studies did not account for individual differences variables that affect disfluency. We show that both matched and unmatched controls produce fewer repairs than individuals with HFA. For silent pauses, there was no difference between matched controls and HFA, but both groups produced more than unmatched controls. These results identify limitations in prior research and shed light on the relationship between autism spectrum disorders and disfluent speech

Genomic Polymorphism of the Pandemic A (H1N1) Influenza Viruses Correlates with Viral Replication, Virulence, and Pathogenicity In Vitro and In Vivo

The novel pandemic A (H1N1) virus was first identified in Mexico in April 2009 and quickly spread worldwide. Like all influenzas, the H1N1 strain-specific properties of replication, virulence, and pathogenicity are a result of the particular genomic sequence and concerted expression of multiple genes. Thus, specific mutations may support increased virulence and may be useful as biomarkers of potential threat to human health. We performed comparative genomic analysis of ten strains of the 2009 pandemic A (H1N1) influenza viruses to determine whether genotypes associated with clinical phenotypes, which ranged from mild to severe illness and up to lethal. Virus replication capacity was tested for each strain in vitro using cultured epithelial cells, while virulence and pathogenicity were investigated in vivo using the BALB/c mouse model. The results indicated that A/Sichuan/1/2009 strain had significantly higher replication ability and virulence than the other strains, and five unique non-synonymous mutations were identified in important gene-encoding sequences. These mutations led to amino acid substitutions in HA (L32I), PA (A343T), PB1 (K353R and T566A), and PB2 (T471M), and may be critical molecular determinants for replication, virulence, and pathogenicity. Our results suggested that the replication capacity in vitro and virulence in vivo of the 2009 pandemic A (H1N1) viruses were not associated with the clinical phenotypes. This study offers new insights into the transmission and evolution of the 2009 pandemic A (H1N1) virus

Patterns of care in testicular torsion: Influence of hospital transfer on testicular outcomes

OBJECTIVE: To investigate patterns of care for testicular torsion and influence of hospital transfers on testicular outcomes. Hospital transfer may be a source of treatment delay in a condition where delays increase likelihood of orchiectomy. METHODS: We used a retrospective cohort of Californian males with ICD-9/CPT-defined torsion from inpatient, emergency department (ED), and ambulatory surgery center (ASC) data. Logistic regression assessed predictors of orchiectomy. RESULTS: Predictors of orchiectomy were ages <1 year (OR 19.2, 95% CI 6.3–58.9), 1–9 years (OR 2.7, 95% CI 1.4–5.2), and ≥40 years (OR 6.6, 95% CI 3.1–13.9) (vs. masked age). Treatment at mid-volume (vs. high-volume) facilities was associated with lower odds of orchiectomy (OR 0.5, 95% CI 0.3–0.7). Rural location, non-private insurance, and hospital transfer were associated with orchiectomy on univariate but not multivariate analysis. During 2008–2010, 2,794 subjects experienced torsion (average incidence 5.08 per 100,000 males yearly). Encounters occurred in ASCs (55%), inpatient facilities (36%), and EDs (9%). 60% of subjects were privately insured, 2% experienced hospital transfer, and 31% underwent orchiectomy. CONCLUSION: Our census found that most cases of testicular torsion were treated in outpatient settings. Hospital transfer was not associated with orchiectomy

Integrative omics framework for characterization of coral reef ecosystems from the Tara Pacific expedition

Abstract Coral reef science is a fast-growing field propelled by the need to better understand coral health and resilience to devise strategies to slow reef loss resulting from environmental stresses. Key to coral resilience are the symbiotic interactions established within a complex holobiont, i.e. the multipartite assemblages comprising the coral host organism, endosymbiotic dinoflagellates, bacteria, archaea, fungi, and viruses. Tara Pacific is an ambitious project built upon the experience of previous Tara Oceans expeditions, and leveraging state-of-the-art sequencing technologies and analyses to dissect the biodiversity and biocomplexity of the coral holobiont screened across most archipelagos spread throughout the entire Pacific Ocean. Here we detail the Tara Pacific workflow for multi-omics data generation, from sample handling to nucleotide sequence data generation and deposition. This unique multidimensional framework also includes a large amount of concomitant metadata collected side-by-side that provide new assessments of coral reef biodiversity including micro-biodiversity and shape future investigations of coral reef dynamics and their fate in the Anthropocene
