Determining the incidence and risk factors for short-term complications following distal biceps tendon repair

Background Distal biceps rupture is a relatively uncommon injury that can significantly affect quality of life. Early complications following biceps tendon repair are not well described in the literature. This study utilizes a national surgical database to determine the incidence of and predictors for short-term complications following distal biceps tendon repair. Methods The American College of Surgeons’ National Surgical Quality Improvement Program database was used to identify patients undergoing distal biceps repair between January 1, 2011, and December 31, 2017. Patient demographic variables of sex, age, body mass index, American Society of Anesthesiologists class, functional status, and several comorbidities were collected for each patient, along with 30-day postoperative complications. Binary logistic regression was used to calculate risk ratios for these complications using patient predictor variables. Results Early postoperative surgical complications (0.5%)—which were mostly infections (0.4%)—and medical complications (0.3%) were rare. A readmission risk factor was diabetes (risk ratio [RR], 4.238; 95% confidence interval [CI], 1.180–15.218). Non-home discharge risk factors were smoking (RR, 3.006; 95% CI, 1.123–8.044) and ≥60 years of age (RR, 4.150; 95% CI, 1.611– 10.686). Maleness was protective for medical complications (RR, 0.024; 95% CI, 0.005–0.126). Surgical complication risk factors were obese class II (RR, 4.120; 95% CI, 1.123–15.120), chronic obstructive pulmonary disease (COPD; RR, 21.981; 95% CI, 3.719–129.924), and inpatient surgery (RR, 8.606; 95% CI, 2.266–32.689). Conclusions Complication rates after distal biceps repair are low. Various patient demographics, medical comorbidities, and surgical factors were all predictive of short-term complications

Absorption by dissociative continua and Rydberg states in condensed matter: HCl in rare gas matrixes

The absorption spectra of HCl in rare gas matrixes were recorded in the 1st continuum (A 1P->X 1S+) region in Kr and Xe matrixes and up to 100 nm in Ar matrixes. Concn. and temp. effects were used to distinguish between absorption from monomers and that from clusters. The 1st continuum band of the monomer is seen to shift red by .apprx.0.36 eV in Ar matrixes, while it shifts blue by .apprx.0.3 and .apprx.0.08 eV in Kr and Xe matrixes, resp. Simultaneously, the oscillator strength of the A 1P state increases drastically in the sequence Ar-Kr-Xe. These trends can be interpreted by the fact that the excited state is solvated in Ar by dispersive and inductive interactions with the environments, while in Kr and Xe matrixes, absorption is dominated by HCl--Rgn+ charge transfer states (Rg = Kr, Xe). At higher energies and in Ar matrixes, discrete absorption by the b 3P, C 1P, H 1S+, K 1P and M 1P states occurs and their relative intensities reproduce well those of the gas phase. However, the b and C states are blue shifted with respect to their gas phase energies by .apprx.0.6 eV, in agreement with their predicted Rydberg character, while the H, K and M states are just slightly red shifted casting some doubt about their classification as Rydberg states.

Cage exit probability versus excess energy in the photodissociation of matrix-isolated HCl

Dissocn. efficiencies for excitation of the repulsive A 1P state of HCl were recorded in Xe, Kr, and Ar matrixes for photon energies between 5 and 10 eV from the content of dissocn. products and quantum efficiencies were derived with the absorption spectra. Influence of temp. and prepn. conditions was investigated. The quantum efficiency rises monotonically in Xe from an excess energy of 1.4 eV above the gas phase dissocn. energy on, sats. around 2.4 eV and remains then essentially const. up to 4 eV. In Ar and Kr, it sats. around 2 eV and in Ar an abs. efficiency of about 0.18 is detd. at 3.7 eV. Results of mol. dynamics calcns. and a statistical model agree qual. but the obsd. satn. at low excess energies is not well described and the absence of a temp. effect in Ar needs further consideration.

Individual Differences in Implicit Bias Can Be Measured Reliably by Administering the Same Implicit Association Test Multiple Times

The use of the Implicit Association Test (IAT) as a measure of individual differences is stymied by insufficient test-retest reliability for assessing trait-level constructs. We assess the degree to which the IAT measures individual differences and test a method to improve its validity as a trait measure: aggregating across IATs. Across three studies, participants (total n = 960) completed multiple IATs in the same session or across multiple sessions. Using latent-variable models, we found that half of the variance in IAT scores reflects individual differences. Aggregating across multiple IATs approximately doubled the variance explained with explicit measures compared with a single IAT D-score. These findings show that IAT scores contain considerable noise and that a single IAT is inadequate to estimate trait bias. However, aggregation across multiple administrations can correct this and better estimate individual differences in implicit attitudes
