Log-rank testing showed a significantly longer RFS for the patients treated with anti-PD-1 [15.3 months; interquartile range (IQR), 8.2-23.2 months; p = 0.04] or BRAF/MEKi (17.9 months; IQR, 12.5-23 months; p = 0.01) than for those treated with surgery alone (11.9 months; IQR, 7.0-17.6 months). In the anti-PD-1 group, AEs occurred less frequently than in the BRAF/MEKi group (54% vs 80%; p = 0.03). Conclusions Adjuvant anti-PD-1 and BRAF/MEKi were associated with significantly improved RFS for the patients with resected stage 3 or 4 melanoma. The BRAF/MEKi group had significantly more AEs than the anti-PD-1 group. This is the first study to characterize real-world recurrence in the modern era of adjuvant therapy for melanoma.This article demonstrates the power and flexibility of linear mixed-effects models (LMEMs) to investigate high-density surface electromyography (HD-sEMG) signals. The potentiality of the model is illustrated by investigating the root mean squared value of HD-sEMG signals in the tibialis anterior muscle of healthy (n = 11) and individuals with diabetic peripheral neuropathy (n = 12). We started by presenting the limitations of traditional approaches by building a linear model with only fixed effects. Then, we showed how the model adequacy could be increased by including random effects, as well as by adding alternative correlation structures. The models were compared with the Akaike information criterion and the Bayesian information criterion, as well as the likelihood ratio test. The results showed that the inclusion of the random effects of intercept and slope, along with an autoregressive moving average correlation structure, is the one that best describes the data (p less then 0.01). Furthermore, we demonstrate how the inclusion of additional variance structures can accommodate heterogeneity in the residual analysis and therefore increase model adequacy (p less then 0.01). Thus, in conclusion, we suggest that adopting LMEM to repeated measures such as electromyography can provide additional information from the data (e.g. test for alternative correlation structures of the RMS value), and hence provide new insights into HD-sEMG-related work.In the original article, third author name has been published incorrectly.Purpose To evaluate the impact on cost, time, resource use, and clinic workflow of converting the route of drug administration from a neurokinin-1 receptor antagonist (NK-1 RA) 30-min intravenous (IV) infusion to aprepitant IV, and more specifically to IV push, within a multicenter community oncology practice. Methods This was a retrospective, multicenter time, motion, and resource/cost evaluation study. Conversion to aprepitant IV was determined by calculating number of doses of aprepitant IV versus fosaprepitant administered in patients receiving moderately or highly emetogenic chemotherapy regimens. Operational advantages (i.e., supply costs, time saved) of switching from fosaprepitant IV infusion to aprepitant administered as a 2-min IV push were assessed. Results A total of 12,908 doses of aprepitant IV 130 mg were administered at 13 Rocky Mountain Cancer Centers clinics over an 18-month period. Conversion from fosaprepitant to aprepitant IV reached 90% after 9 months of aprepitant IV initiation. Supply costs per administration were reduced ($2.51 to $0.52) when aprepitant was prepared as an IV push versus an NK-1 RA infusion. The overall time savings per administration of aprepitant was reduced by 90% (from 36.5 to 3.5 min, 33 min saved) as an IV push rather than an infusion. Most of the time saved per administration (30 min) pertained to the infusion nurse, and 3 min was saved by the pharmacy technician. Conclusion Successful conversion to aprepitant, and specifically to a 2-min IV push, provides time, cost, and resource savings, improves operational efficiency, and avoids the negative impact of potential future IV fluid shortages.Background Programmed death-ligand 1 (PD-L1) expression on immune cells (ICs) is a predictive marker for PD-L1 checkpoint blockade in patients with triple-negative breast cancer (TNBC). However, the level of PD-L1 expression and the percentage of cells that are PD-L1+ are continuous variables not dichotomous variables for tumor-infiltrating lymphocytes (TILs) and other cells. Methods Multiplexed immunohistochemistry was applied to 31 archived surgical specimens from untreated TNBC patients. TIL levels were visually scored, and CD8+ T cells and PD-L1+ ICs were quantified using an automated multispectral imaging system. PD-L1 expression was assessed within a multiplexed context (CD8 combined spectral composite). Results The mean value of stromal TILs (i.e., the percentage of the stromal area with a dese mononuclear infiltrate) was 20%. The frequency of patients with PD-L1-positive tumor cells (TC) and ICs was 38.7% and 32.2%, respectively, with a significant association between them. TIL levels were correlated with CD8+ T cell infiltration in the stroma (Spearman r = 0.795, p less then 0.0001). PD-L1 expression on IC was significantly associated with TIL levels (Spearman r = 0.790, p less then 0.001) and infiltration of CD8+ T cells (Spearman r = 0.683, p less then 0.0001). Conclusions The level of PD-L1 on IC was correlated with the level of PD-L1 on TC as well as TIL levels and infiltration of CD8+ T cells. These results suggest that high PD-L1 on IC may reflect T cell-inflamed tumors with the amount of TILs present, including the CD8+ T cells required for anti-tumor responses.In a first principle computational study, using density functional theory, we have identified four types of 2D carbon sheets, similar to graphene, made entirely of non-regular hexagons. In one case, we get a structure where the non-regular hexagons have four sides of length d1 = 1.416 Å and two sides of length d2 = 1.68 Å. see more Next case, in the non-regular hexagons the side d1 (two times) and d2 (four times) are exchanged. In two other cases, the non-regular hexagons have three pairs (opposite sides) of different lengths (d1 = 1.529 Å, d2 = 1.567 Å, and d3 = 1.612 Å; d1 = 1.387 Å, d2 = 1.348 Å, and d3 = 1.387 Å). By propper choice of the non-regular hexagon sides, one could arrive at a 2D carbon system like graphene, but with a tunable band gap. The structure is more stable when the system has more number of regular C-C bonds than the longer C-C bonds. Due to its non-regular hexagons, special atomic configuration, this system may have, like graphene, unusual properties. It is semiconducting, and there is no need to functionalize it for opening the band gap as is the case with graphene.
