Patients with MI ideas about their personal risk of future MI are not congruent with their clinical risk assessments. Inpatient hospital care appears to be unsuccessful in communicating prognosis effectively to patients. Improving the accuracy of risk perceptions may help decrease unnecessary cardiac anxiety and invalidism in some patients and prompt risk-reducing behaviours in others.

BackgroundMany molecules are flexible and undergo significant shape deformation as part of their function, and yet most existing molecular shape comparison (MSC) methods treat them as rigid bodies, which may lead to incorrect shape recognition.ResultsIn this paper, we present a new shape descriptor, named Diffusion Distance Shape Descriptor (DDSD), for comparing 3D shapes of flexible molecules. The diffusion distance in our work is considered as an average length of paths connecting two landmark points on the molecular shape in a sense of inner distances. The diffusion distance is robust to flexible shape deformation, in particular to topological changes, and it reflects well the molecular structure and deformation without explicit decomposition. Our DDSD is stored as a histogram which is a probability distribution of diffusion distances between all sample point pairs on the molecular surface. Finally, the problem of flexible MSC is reduced to comparison of DDSD histograms.ConclusionsWe illustrate that DDSD is insensitive to shape deformation of flexible molecules and more effective at capturing molecular structures than traditional shape descriptors. The presented algorithm is robust and does not require any prior knowledge of the flexible regions.

Objective This study aims to assess trends in applicant-reported costs of the otolaryngology residency application process between 2019 and 2021 and evaluate the impact of application costs on number of interview offers. Study Design Cross-sectional study. Setting US allopathic and osteopathic medical schools. Methods Survey data from applicants were obtained from the Texas STAR database (Seeking Transparency in Application to Residency) for the years 2019 to 2021. Outcomes included total cost, interview cost, other costs, application fees, and number of interview offers. Simple and multivariable linear regression was used to identify novel predictors of cost and assess the correlation between cost and interview offers. Results Among 363 otolaryngology applicants, there was a 74% reduction in total costs and a 97% reduction in interview costs in the 2021 cycle vs the 2020 cycle. Significant predictors of total cost among otolaryngology applicants included the number of away rotations ( P < .01), the number of research experiences ( P = .04), and couples matching ( P < .01). During the 2019 and 2020 application cycles, there was a significant association between applicant-reported total spending and number of otolaryngology interview offers ( P < .01), which was not present during the 2021 cycle ( P = .35). Conclusion Number of otolaryngology interview offers appears to be directly correlated with applicant-reported total costs regardless of number of applications or interviews attended, which may be a source of inequality in the application process. There was a drastic reduction in total costs, interview costs, and other costs during the COVID-19 pandemic, which was likely driven by virtual interviewing and the absence of away rotations.

Water content determined by gravimetric adjustment of the known volumetric relationship was slightly more than 2% less, on average, than that stated by contact lens manufacturers. This was likely the result of the greater tonicity of the storage solution in this study or more pronounced blotting prior to measurement, or both; yet the soft lenses and blotting method were the same as used for Dk assessment. Commercially available soft lenses were consistently manufactured, the blotting method was sufficient, and the polarographic Dk methodology was reliable such that linear resistance (t/Dk) versus thickness (t) plots resulted from lenses of different lots made of material having the same name. The semilogarithmic relationship of Dk and water content survived correction for boundary layers, correction for the edge effect, and calibration. Logically, the next step would be to refine this relationship even further by determining water content at the same temperature as oxygen permeability, 35 degrees C.

Protein-protein interaction (PPI) network analysis presents an essential role in understanding the functional relationship among proteins in a living biological system. Despite the success of current approaches for understanding the PPI network, the large fraction of missing and spurious PPIs and a low coverage of complete PPI network are the sources of major concern. In this paper, based on the diffusion process, we propose a new concept of global geometric affinity and an accompanying computational scheme to filter the uncertain PPIs, namely, reduce the spurious PPIs and recover the missing PPIs in the network. The main concept defines a diffusion process in which all proteins simultaneously participate to define a similarity metric (global geometric affinity (GGA)) to robustly reflect the internal connectivity among proteins. The robustness of the GGA is attributed to propagating the local connectivity to a global representation of similarity among proteins in a diffusion process. The propagation process is extremely fast as only simple matrix products are required in this computation process and thus our method is geared toward applications in high-throughput PPI networks. Furthermore, we proposed two new approaches that determine the optimal geometric scale of the PPI network and the optimal threshold for assigning the PPI from the GGA matrix. Our approach is tested with three protein-protein interaction networks and performs well with significant random noises of deletions and insertions in true PPIs. Our approach has the potential to benefit biological experiments, to better characterize network data sets, and to drive new discoveries.
