Importance: Unplanned hospital readmission is costly and in recent years has become a focus of health care legislation intended to reduce health care expenditures. Greater understanding of which perioperative complications are associated with hospital readmission after surgery for head and neck cancer is needed to reduce unplanned readmissions. Objective: To determine which clinical risk factors and complications are associated with 30-day unplanned readmission after surgery for malignant neoplasms of the head and neck...

Adolescents' evaluations of discriminatory race-based humor and their expectations about peer responses to discrimination were investigated in 8th- (Mage  = 13.80) and 10th-grade (Mage  = 16.11) primarily European-American participants (N = 256). Older adolescents judged race-based humor as more acceptable than did younger adolescents and were less likely to expect peer intervention. Participants who rejected discrimination were more likely to reference welfare/rights and prejudice and to anticipate that peers would intervene...

This study establishes a new trans-metal-trapping (TMT) procedure based on a mixture of LiTMP (the base) and tris(trimethylsilylmethyl)gallium [Ga(CH2 SiMe3 )3 , GaR3 ] (the trap) that, operating in a tandem manner, is effective for the regioselective deprotonation of sensitive diazines in hydrocarbon solution, as illustrated through reactions of pyrazine, pyridazine, and pyrimidine, as well as through the N-S heterocycle benzothiazole. The metallo-activated complexes of all of these compounds were isolated and structurally defined...

We linked UK cancer registry data with the corresponding electronic primary care medical records of 6080 patients who died of cancer over a 7-year period in a large United Kingdom city. We extracted all prescriptions for analgesics issued to each patient in the linked cohort during the 12 months before death and analysed the extent and duration of strong opioid treatment with clinical and patient characteristics. Strong opioids were prescribed for 48% of patients in the last year of life. Median interval between first prescription of a strong opioid and death was 9 weeks (interquartile range 3-23)...

Dietary restriction (DR) extends lifespan and healthspan in many species, but precisely how it elicits its beneficial effects is unclear. We investigated the impact of DR on mitochondrial function within liver and skeletal muscle of female ILSXISS mice that exhibit strain-specific variation in lifespan under 40% DR. Strains TejJ89 (lifespan increased under DR), TejJ48 (lifespan unaffected by DR) and TejJ114 (lifespan decreased under DR) were studied following 10 months of 40% DR (13 months of age). Oxygen consumption rates (OCR) within isolated liver mitochondria were unaffected by DR in TejJ89 and TejJ48, but decreased by DR in TejJ114...

Bulky amido ligands are precious in s-block chemistry, since they can implant complementary strong basic and weak nucleophilic properties within compounds. Recent work has shown the pivotal importance of the base structure with enhancement of basicity and extraordinary regioselectivities possible for cyclic alkali metal magnesiates containing mixed n-butyl/amido ligand sets. This work advances alkali metal and alkali metal magnesiate chemistry of the bulky arylsilyl amido ligand [N(SiMe3 )(Dipp)](-) (Dipp=2,6-iPr2 -C6 H3 )...

Single-wall carbon nanotubes present unique opportunities for drug delivery, but have not advanced into the clinic. Differential nanotube accretion and clearance from critical organs have been observed, but the mechanism not fully elucidated. The liver has a complex cellular composition that regulates a range of metabolic functions and coincidently accumulates most particulate drugs. Here we provide the unexpected details of hepatic processing of covalently functionalized nanotubes including receptor-mediated endocytosis, cellular trafficking and biliary elimination...

Juveniles who have committed sexual offenses are subject to specialized treatment and policies based on their assumed unique dangerousness, despite contradictory evidence. Limited information is available regarding risk factors and their relationships to outcomes in this population. The comparative frequency and predictive utility of empirically supported risk factors for general delinquency were examined using data from the Pathways to Desistance study. Adolescent males who committed sexual offenses (n = 127) were compared to adolescent males who committed non-sexual offenses (n = 1021)...

The precision of an eye-tracker is critical to the correct identification of eye movements and their properties. To measure a system's precision, artificial eyes (AEs) are often used, to exclude eye movements influencing the measurements. A possible issue, however, is that it is virtually impossible to construct AEs with sufficient complexity to fully represent the human eye. To examine the consequences of this limitation, we tested currently used AEs from three manufacturers of eye-trackers and compared them to a more complex model, using 12 commercial eye-trackers...

PURPOSE: We examine whether and how much risk/need indicators change over time in a sample of serious adolescent offenders and whether changes in risk are related to self-reported and official record reports of offending in the year following assessment. METHODS: Growth curve and multilevel mixed-effects models are used to examine change through age 18 in a sample of 1,354 serious adolescent offenders participating in the Pathways to Desistance Study. RESULTS: Three primary findings emerge: 1) Compared to the baseline assessment, overall risk/need scores decrease over time...

In individuals with sepsis, the infecting microbes are commonly viewed as generic inducers of inflammation while the host background is considered the primary variable affecting disease progression and outcome. To study the effects of bacterial strain differences on the maladaptive immune responses that are induced during sepsis, we employed a novel zebrafish embryo infection model using extraintestinal pathogenic Escherichia coli (ExPEC) isolates. These genetically diverse pathogens are a leading cause of sepsis and are becoming increasingly dangerous because of the rise of multidrug-resistant strains...

Sub-cellular localisation of proteins is an essential post-translational regulatory mechanism that can be assayed using high-throughput mass spectrometry (MS). These MS-based spatial proteomics experiments enable us to pinpoint the sub-cellular distribution of thousands of proteins in a specific system under controlled conditions. Recent advances in high-throughput MS methods have yielded a plethora of experimental spatial proteomics data for the cell biology community. Yet, there are many third-party data sources, such as immunofluorescence microscopy or protein annotations and sequences, which represent a rich and vast source of complementary information...

Intermittent vagus nerve stimulation (VNS) can reduce the frequency of seizures in patients with refractory epilepsy, but can affect respiration in sleep. Untreated obstructive sleep apnea (OSA) can worsen seizure frequency. Unfortunately, OSA and VNS-induced sleep disordered breathing (SDB) may occur in the same patient, leading to a therapeutic dilemma. We report a pediatric patient in whom OSA improved after tonsillectomy, but coexistent VNS-induced SDB persisted. With decrease in VNS output current, patient's SDB improved, but seizure activity exacerbated, which required a return to the original settings...

To investigate children's understanding of intergroup transgressions, children (3-8 years, N = 84) evaluated moral and conventional transgressions that occurred among members of the same gender group (ingroup) or members of different gender groups (outgroup). All participants judged moral transgressions to be more wrong than conventional transgressions. However, when asked to make a judgment after being told an authority figure did not see the transgression, younger participants still judged that moral violations were less acceptable than conventional transgressions, but judged both moral and conventional transgressions with an outgroup victim as more acceptable than the corresponding transgressions with an ingroup victim...
