Abstract Background: Simplified projected aortic valve area (EOAproj) is a valuable echocardiographic parameter in the evaluation of low flow low gradient aortic stenosis (LFLG AS). Its widespread use in clinical practice is hampered by the laborious process of flow rate (Q) calculation. Objetive: This study proposes a less burdensome, alternative method of Q calculation to be incorporated in the original formula of EOAproj and measures the agreement between the new proposed method of EOAproj calculation and the original one. Methods: Retrospective observational single-institution study that included all consecutive patients with classic LFLG AS that showed a Q variation with dobutamine infusion ≥ |15|% by both calculation methods. Results: Twenty-two consecutive patients with classical LFLG AS who underwent dobutamine stress echocardiography were included. Nine patients showed a Q variation with dobutamine infusion calculated by both classical and alternative methods ≥ |15|% and were selected for further statistical analysis. Using the Bland-Altman method to assess agreement we found a systematic bias of 0,037 cm2 (95% CI 0,004 - 0,066), meaning that on average the new method overestimates the EOAproj in 0,037 cm2 compared to the original method. The 95% limits of agreement are narrow (from -0,04 cm2 to 0,12 cm2), meaning that for 95% of individuals, EOAproj calculated by the new method would be between 0,04 cm2 less to 0,12 cm2 more than the EOAproj calculated by the original equation. Conclusion: The bias and 95% limits of agreement of the new method are narrow and not clinically relevant, supporting the potential interchangeability of the two methods of EOAproj calculation. As the new method requires less additional measurements, it would be easier to implement in clinical practice, promoting an increase in the use of EOAproj.

Valproate is the most effective treatment for idiopathic generalised epilepsy. Currently, its use is restricted in women of childbearing potential owing to high teratogenicity. Recent evidence extended this risk to men’s offspring, prompting recommendations to restrict use in everybody aged <55 years. This study will evaluate mortality and morbidity risks associated with valproate withdrawal by emulating a hypothetical randomised-controlled trial (called a “target trial”) using retrospective observational data. The data will be drawn from ~250m mainly US patients in the TriNetX repository and ~60m UK patients in Clinical Practice Research Datalink (CPRD). These will be scanned for individuals aged 16–54 years with epilepsy and on valproate who either continued, switched to lamotrigine or levetiracetam, or discontinued valproate between 2014–2024, creating four groups. Randomisation to these groups will be emulated by baseline confounder adjustment using g-methods. Mortality and morbidity outcomes will be assessed and compared between groups over 1–10 years, employing time-to-first-event and recurrent events analyses. A causal prediction model will be developed from these data to aid in predicting the safest alternative antiseizure medications. Together, these findings will optimise informed decision-making about valproate withdrawal and alternative treatment selection, providing immediate and vital information for patients, clinicians and regulators.

Missing data is a frequent occurrence in both small and large datasets. Among other things, missingness may be a result of coding or computer error, participant absences, or it may be intentional, as in a planned missing design. Whatever the cause, the problem of how to approach a dataset with holes is of much relevance in scientific research. First, missingness is approached as a theoretical construct, and its impacts on data analysis are encountered. I discuss missingness as it relates to structural equation modeling and model fit indices, specifically its interaction with the Root Mean Square Error of Approximation (RMSEA). Data simulation is used to show that RMSEA has a downward bias with missing data, yielding skewed fit indices. Two alternative formulas for RMSEA calculation are proposed: one correcting degrees of freedom and one using Kullback-Leibler divergence to result in an RMSEA calculation which is relatively independent of missingness. Simulations are conducted in Java, with results indicating that the Kullback-Leibler divergence provides a better correction for RMSEA calculation. Next, I approach missingness in an applied manner with an existing large dataset examining ideology measures. The researchers assessed ideology using a planned missingness design, resulting in high proportions of missing data. Factor analysis was performed to gauge uniqueness of ideology measures.

The formation of fullerooxazoles from C61HPh3− has been examined in benzonitrile (PhCN), m-methoxybenzonitrile (m-OCH3PhCN), m-tolunitrile (m-CH3PhCN), and o-tolunitrile (o-CH3PhCN), where cis-1 bisadducts with Ph-, m-OCH3Ph-, m-CH3Ph-, and o-CH3Ph-substituted cyclic imidate next to the phenylmethano are formed as evidenced by various characterizations. Interestingly, only regioisomers 2a−d with the oxygen atom bonded to C4/C5 and the nitrogen atom bonded to C3/C6 are generated as demonstrated by heteronuclear multiple bond coherence (HMBC) NMR, while the alternative regioisomers 3a−d, which have the oxygen and nitrogen atoms at C3/C6 and C4/C5, respectively, are not formed from the reactions, even though the DFT (density functional theory) calculations have predicted that the energy differences between the two types of regioisomers are very small, with regioisomers 3a−d actually having lower energies than 2a−d. The results are rationalized by the charge distributions of C61HPh3−, where computational calculations have shown that the negative charges on C4 and C5 are greater than those on C3 and C6, indicating that the exhibited site selectivity of heteroatoms is a result of the charge-directed addition process.

In the field of quantitative proteomics, the Isobaric Tags for Relative & Absolute Quanti-tation (iTRAQ) technology has demonstrated efficacy for proteome monitoring despite its lack of a consensus for data handling. In this study, after peptide and protein identification, we com-pared the widespread quantitation method based on the calculation of MS/MS reporter ion peaks areas ratios (Protein Pilot) to the alternative method based on the calculation of ratios of the sum of peak intensities (jTRAQx (Quant)) and we processed output data with the in-house Customi-zable iTRAQ Ratios Calculator (CiR-C) algorithm. Quantitation based on peak area ratios dis-played no significant linear correlation with Western blot quantitation. On the contrary, quantita-tion based on the sum of peak intensities displayed a significant linear association with Western blot quantitation (non-zero slope; Pearson correlation coefficient test, r = 0.2962, p = 0.0099 **) with an average bias of 0.08747 ± 0.5004 and 95% Limits of Agreement from - 0.8932 to 1.068. We proposed the Mascot-jTRAQx-CiR-C strategy as a simple yet powerful data processing ad-junct to the iTRAQ technology

Surfactant-free microemulsion (SFME) represents a class of fluid mixtures that can form microheterogeneous structures without detergents, offering an environmentally benign alternative to traditional microemulsions. However, the formation mechanism is still elusive. This work applies the Kirkwood–Buff theory to mixtures of alcohols, water, and n-hexane to elucidate the SFME formation mechanism. To ensure robust calculation of the Kirkwood–Buff integrals (KBIs), we construct a data set of densities and excess free energies of binary and ternary systems. Multiple excess Gibbs free energy models are assessed against this data set to select the most suitable model reproducing the experimental results. In addition, we introduce statistical methods to determine the optimal polynomial order of the Redlich–Kister correlation for the excess volume data. We first validate our methodology in binary systems. Then, we extend the calculation method to ternary mixtures. The KBI calculation results reveal that the alcohol-hexane and water–hexane interactions do not significantly affect SFME formation. In contrast, the interplay among water–water, water–alcohol, and alcohol–alcohol interactions critically influences the ability of a liquid mixture to form SFME structures. SFME systems exhibit the facile formation of water aggregates enveloped by alcohols, whereas non-SFME systems demonstrate homogeneous alcohol/water droplets dispersed in an oil continuous medium.

The 3D-QSAR method comparative molecular field analysis (CoMFA) involves the estimation of atomic partial charges as part of the process of calculating molecular electrostatic fields. Using 30 data sets from the literature the effect of using different common partial charge calculation methods on the predictivity (cross-validated R2) of CoMFA was studied. The partial charge methods ranged from the popular Gasteiger and the newer MMFF94 electronegativity equalization methods, to the more complex and computationally expensive semiempirical charges AM1, MNDO, and PM3. The MMFF94 and semiempirical MNDO, AM1, and PM3 methods for computing charges were found to result in statistically significantly more predictive CoMFA models than the Gasteiger charges. Although there was a trend toward the semiempirical charges performing better than the MMFF94 charges, the difference was not statistically significant. Thus, semiempirical partial charge calculation methods are suggested for the most predictive CoMFA models, but the MMFF94 charge calculation method is a very good alternative if semiempirical methods are not available or faster calculation speed is important.

The description of core electrons is important for calculating a number of chemical properties using computational quantum chemistry. Though many existing specialized all-Gaussian basis sets for core-dependent properties out-perform general-purpose all-Gaussian basis sets, the underlying deficiencies of Gaussian basis sets when describing the core region of the electronic wave function persist, which limits accuracy and increases computational cost. A promising alternative to traditional all-Gaussian basis sets are mixed ramp-Gaussian basis sets. Previous investigations which focused on simply replacing core basis functions with ramp functions failed to provide the anticipated improvements in performance. For the first time, we present parametrizations for fully optimized mixed ramp-Gaussian basis sets in the form of the RS‐n basis sets. Using pseudo ramp functions to approximate the ramps, basis set performance for these new mixed ramp-Gaussian basis sets is evaluated. Through multiple benchmark studies, the importance of fully optimizing the nonpolarization Gaussian functions in mixed ramp-Gaussian basis sets is confirmed. These investigations also show mixed ramp-Gaussian basis sets to have significant promise for the efficient calculation of core-dependent properties.
