The use of crystal engineering to control the supramolecular arrangement of π-conjugated molecules in the solid-state is of considerable interest for the development of novel organic electronic materials. In this study, we investigated the effect of combining of two types of supramolecular interaction with different geometric requirements, amide hydrogen bonding and π-interactions, on the π-overlap between calamitic π-conjugated cores. To this end, we prepared two series of bithiophene diesters and diamides with methylene, ethylene, or propylene spacers between the bithiophene core and the functional groups in their terminal substituents. The hydrogen-bonded bithiophene diamides showed significantly denser packing of the bithiophene cores than the diesters and other known α,ω-disubstituted bithiophenes. The bithiophene packing density reach a maximum in the bithiophene diamide with an ethylene spacer, which had the smallest longitudinal bithiophene displacement and infinite 1D arrays of electronically conjugated, parallel, and almost linear N-H⋅⋅⋅O=C hydrogen bonds. The synergistic hydrogen bonding and π-interactions were attributed to the favorable conformation mechanics of the ethylene spacer and resulted in H-type spectroscopic aggregates in solid-state absorption spectroscopy. These results demonstrate that the optoelectronic properties of π-conjugated materials in the solid-state may be tailored systematically by side-chain engineering, and hence that this approach has significant potential for the design of organic and polymer semiconductors.
The combined impact of variable surgeon prescribing preferences and low resident prescribing comfort level can lead to significant disparity in opioid prescribing patterns for the same surgery in the same academic surgical practice. We report the results of a resident led initiative to standardize postoperative prescription practices within the Department of Otolaryngology at a single tertiary-care academic hospital in order to reduce overall opioid distribution.

Retrospective cohort study.

Following approval by the Institutional Review Board, performed a retrospective review of 12 months before (July 2016-June 2017) and after (July 2017-June 2018) implementation of the Postoperative Analgesia Protocol, which included all adults undergoing tonsillectomy, septoplasty, thyroidectomy, parathyroidectomy, tympanoplasty, middle ear exploration, stapedectomy, and ossicular chain reconstruction.

Seven hundred and thirty eight procedures met inclusion criteria. Following implementation, total morphine milligram equivalents decreased by 26% (P < .0001). The number of patients requiring opioid refills decreased by 49%, and morphine milligram equivalents received as refills decreased by 16% (P < .001). Thyroid and parathyroid surgery had the greatest reduction in morphine milligram equivalents prescribed (84%, P < .001), followed by septoplasty (30%, P = .001) and tonsillectomy (18%, P < .001). The number of patients receiving refills of opioid medications decreased for all procedures (tonsillectomy 54%; septoplasty 67%; thyroid/parathyroid surgery 80%, middle ear surgery 100%).

While every patient and surgery must be treated individually, this study demonstrates that a resident led standardization of pain control regimes can result in significant reductions in total quantity of opioids prescribed.

Pinpointing which genes and genomic regions are underlying phenotypic variability thus helps to understand the processes of acclimation and adaptation. We used Daphnia as a system to identify candidates playing a role in phenotypic variation related to a predation risk environment with a genome-wide association approach. Furthermore, a gene co-expression network analysis allowed identifying clusters of co-expressed genes which correlated to life history traits. To enhance the understanding of the functional roles of the transcripts, we identified orthologs and paralogs from related species and used ontologies to annotate the candidates of interest. Our study revealed that only one life history trait and two morphometric traits have a genetic association in the presence of predation risk (fish kairomones), whereas most genotype-phenotype associations were detected in a genotype-environment interaction analysis for reproduction-related phenotypic traits. The gene co-expression network analysis identified a total of 44 modules, of which one module correlated to another life history trait namely the 'total number of broods'. The combined use of gene co-expression network and transcriptome-wide association analysis allowed the identification of 131 candidate transcripts associated with life history traits in Daphnia galeata. These results lay the ground for targeted studies to further understand phenotypic variability in this species.
Despite being common, neck injuries have received relatively little attention for important quality of care metrics. This study sought to determine the association between blunt and penetrating neck injuries on mortality and length of stay, and to identify additional patient and hospital-level characteristics that impact these outcomes.

Retrospective cohort study utilizing the American College of Surgeons Trauma Quality Improvement Program database.

Adult patients (≥18) who sustained traumatic injuries involving the soft tissues of the neck between 2012 and 2016 were eligible. Multiple imputation was used to account for missing data. Logistic regression and negative binomial models were used to analyze 1) in-hospital mortality and 2) length of stay respectively while adjusting for potential confounders and accounting for clustering at the hospital level.

In a cohort of 20,285 patients, the crude mortality rate was lower in those sustaining blunt neck injuries compared to penetrating injuries (4.9% vs. Bexotegrast manufacturer 6.0%, P < .01), while length of hospital stay was similar (median 9.9 vs. 10.2, P = 0.06). In adjusted analysis, blunt neck injuries were associated with a reduced odds of mortality during hospital admission (odds ratio 0.66, 95% confidence intervals [0.564, 0.788]), as well as significant reductions in length of stay (rate ratio 0.92, 95% confidence intervals [0.880, 0.954]).

Blunt neck injuries are associated with lower mortality and length of stay compared to penetrating injuries. Areas of future study have been identified, including elucidation of processes of care in specific organs of injury.
