BACKGROUND GS-6207 is a first-in-class HIV capsid inhibitor, targeting several functions of the HIV capsid in the viral cycle, including viral particle assembly, capsid formation and nuclear entry. GS-6207 has demonstrated picomolar potency in vitro, activity confirmed by high potency in a Phase 1 clinical study, with a long-acting antiretroviral profile with potential dosing every 6 months. In vitro resistance selections previously conducted with increasing doses of GS-6207 have identified capsid variants with reduced susceptibility to GS-6207. OBJECTIVES To study the prevalence of capsid mutations associated with in vitro resistance to GS-6207 in people living with HIV (PLWH). METHODS Plasma samples from ART-naive or -experienced PLWH, including PI-experienced people, were sequenced and analysed for the presence of capsid variants identified during in vitro resistance selection L56I, M66I, Q67H, K70N, N74D, N74S and T107N. RESULTS Among the samples from the 1500 patients studied, none of the seven GS-6207 resistance mutations identified during in vitro selection experiments was detected, regardless of HIV subtype or PLWH treatment history. CONCLUSIONS Out of the seven HIV capsid substitutions previously selected in vitro and shown to confer phenotypic resistance to GS-6207, none of these seven mutations was observed in this large dataset, suggesting that neither PLWH with previous PI failure nor PLWH with emergence of PI resistance mutations are anticipated to impact GS-6207 activity in these diverse HIV-infected populations. © The Author(s) 2020.

Objective To evaluate annual changes in all-cause mortality, hospitalization rates, and hospitalization-related mortality among dually enrolled beneficiaries and nondually enrolled beneficiaries. Design, Setting, and Participants Serial cross-sectional study of Medicare fee-for-service beneficiaries aged 65 years or older between January 2004 and December 2017. The final date of follow-up was September 30, 2018. Exposures Dual vs nondual enrollment status. Main Outcomes and Measures Annual all-cause mortality rates; all-cause hospitalization rates; and in-hospital, 30-day, 1-year hospitalization-related mortality rates. Results There were 71 017 608 unique Mted outcomes between dually and nondually enrolled beneficiaries persisted during the study period. Conclusions and Relevance Among Medicare fee-for-service beneficiaries aged 65 years or older, dually enrolled beneficiaries had higher annual all-cause mortality, all-cause hospitalizations, and hospitalization-related mortality compared with nondually enrolled beneficiaries. BTK inhibitor solubility dmso Between 2004 and 2017, these differences did not decrease.Impact biomechanics research in occupant safety predominantly focuses on the effects of loads applied to human subjects during automotive collisions. Characterization of the biomechanical response under such loading conditions is an active and important area of investigation. However, critical knowledge gaps remain in our understanding of human biomechanical response and injury tolerance under vertically accelerated loading conditions experienced due to under-body blast (UBB) events. This knowledge gap is reflected in Anthropomorphic Test Devices (ATDs) used to assess occupant safety. Experiments are needed to characterize biomechanical response under UBB relevant loading conditions. Matched pair experiments in which an existing ATD is evaluated in the same conditions as a Post Mortem Human Subject (PMHS) may be utilized to evaluate biofidelity and injury prediction capabilities, as well as ATD durability, under vertical loading. To characterize whole body response in the vertical direction, six whole body PMHS tests were completed under two vertical loading conditions. A series of 50th percentile Hybrid III ATD tests were completed under the same conditions. Ability of the Hybrid III to represent the PMHS response was evaluated using a standard evaluation metric. Tibial accelerations were comparable in both response shape and magnitude, while other sensor locations had large variations in response. Post-test inspection of the Hybrid III revealed damage to the pelvis foam and skin, which resulted in large variations in pelvis response. This work provides an initial characterization of the response of the seated Hybrid III ATD and PMHS under high rate vertical accelerative loading.

Since true class labels are unknown in the unsupervised setting, it is challenging to validate any cluster obtained computationally, an important problem barely addressed by the research community. RESULTS We have developed a toolkit called Covering Point Set (CPS) analysis to quantify uncertainty at the levels of individual clusters and overall partitions. Functions have been developed to effectively visualize the inherent variation in any cluster for data of high dimension, and provide more comprehensive view on potentially interesting subgroups in the data. Applying to three usage scenarios for biomedical data, we demonstrate that CPS analysis is more effective for evaluating uncertainty of clusters comparing to state-of-the-art measurements. We also showcase how to use CPS analysis to select data generation technologies or visualization methods. AVAILABILITY The method is implemented in an R package called OTclust, available on CRAN.
