Abstract:

Objective: The assessment of lipid profiles in children is critical for the early detection of dyslipidemia. Low-density lipoprotein cholesterol (LDL-C) is one of the most often used measures in diagnosing and treating patients with dyslipidemia. Therefore, accurate determination of LDL-C levels is critical for managing lipid abnormalities. In this study, we aimed to compare various LDL-C estimating formulas with powerful machine-learning (ML) algorithms in a Turkish pediatric population. Materials and Methods: This study included 2,563 children under 18 who were treated at Sivas Cumhuriyet Un

Abstract:

Two new formulas, the Martin-Hopkins and the Sampson formula, were recently developed to overcome shortcomings of the Friedewald formula for calculating LDL-cholesterol. We aimed to compare the concordance of the two formulas with apolipoprotein B (apoB), a surrogate marker of the number of LDL particles. In a study of serum lipid data of 1179 patients who consulted the AZ St-Jan Hospital Bruges for cardiovascular risk assessment, the correlation and concordance of the Friedewald, Martin-Hopkins and Sampson formulas with apoB concentration, measured by immunonephelometry, were determined and c

We show that for each Seifert form of an algebraically slice knot with nontrivial Alexander polynomial, there exists an infinite family of knots having the Seifert form such that the knots are linearly independent in the knot concordance group and not concordant to any knot with coprime Alexander polynomial.

Obesity is one of the most important health issues worldwide. According to the Mexican National Survey of Health and Nutrition 2018 “ENSANUT”, 76.8% of women and 73% of men who are 18 years or older are overweight or obese, and the majority are not well diagnosed. One of the greatest difficulties in order to diagnose this disease is the poor correlation between the BMI and the real fat percentage. There are different ways to estimate the fat percentage. Some of them are the formulas based on anthropometric measures. We conducted a retrolective, descriptive, transversal trial to analyze the cor

Abstract:

Introduction: The diagnosis and classification of chronic kidney disease (CKD) are based on the glomerular filtration rate value. The simplest way to evaluate glomerular filtration rate is to estimate it based on serum creatinine concentration using one of many specific mathematical formulas. None of the formulas created for this purpose are perfect. Differences in eGFR values are frequently observed in specific stages of chronic kidney disease by KDIGO classification based on different formulas.

Background: The glomerular filtration rate (GFR) is essential for calculating the dose and the monitoring of carboplatin.

We study the effect of mutation on link concordance and 3-manifolds. We show that the set of links concordant to sublinks of homology boundary links is not closed under positive mutation. We also show that mutation does not preserve homology cobordism classes of 3-manifolds. A significant consequence is that there exist 3-manifolds which have the same quantum SU(2) -invariants but are not homology cobordant. These results are obtained by investigating the effect of mutation on the Milnor [Formula: see text]-invariants, or equivalently the Massey products.

Abstract:

We introduce a new class of links for which we give a lower bound for the slice genus g*, using the generalized Rasmussen invariant. We show that this bound, in some cases, allows one to compute g* exactly; in particular, we compute g* for torus links. We also study another link invariant: the strong slice genus [Formula: see text]. Studying the behavior of a specific type of cobordisms in Lee homology, a lower bound for [Formula: see text] is also given.

Abstract:

For elite athletes, monitoring body composition is important for maximizing performance without health risks. Amplitude (A)-mode ultrasound (AUS) has attracted increasing attention as an alternative to skinfold thickness measurements commonly used for assessing the amount of body fat in athletes. AUS accuracy and precision, however, depend on the formula used to predict body fat percentage (%BF) from subcutaneous fat layer thicknesses. Therefore, this study evaluates the accuracy of the 1-point biceps (B1), 9-sites Parrillo, 3-sites Jackson and Pollock (JP3), and 7-sites Jackson and Pollock (J

Abstract:

Determining the optimal endotracheal tube (ETT) depth in neonates remains challenging for neonatologists. The guideline for optimal ETT depth is based on the patients’ weight or gestational age. However, there is a discrepancy in the suggested ETT depth between these two parameters. The aim of this retrospective study was to compare the recommended weight-based and age-based formulas for optimal ETT depth and obtain the optimal reference before intubation. Participants were assigned to group 1 if the recommended ETT insertion depth based on weight was concordant with the recommended depth base

Abstract:

Accurate estimation of low-density lipoprotein cholesterol (LDL-C) is important for cardiovascular risk assessment and guiding cholesterol-lowering therapy. Due to the high cost of β-quantification (Gold standard) and time-consuming, direct measurement of LDL-C is an alternative method. However, unlike the calculation of LDL-C by Friedewald formula, there is an additional cost in terms of reagents for performing a direct LDL-C test. The current study aimed to compare direct LDL-C concentration determination to data calculated by Friedewald formula. 752 lipid profiles of 710 people with LDL-C e

Background and Purpose— 1/2ABC has been used widely for assessing the volume of intracerebral hematoma. However, it is only suitable for calculating regular and small volume hematomas. Therefore, we re-explored the formula of hematoma volume to find a method that can calculate hematoma volumes accurately, reliably, and quickly. Methods— Computed tomography imaging data of 257 patients with intracerebral hemorrhage were collected. Hematoma volumes were estimated using 3-dimensional Slicer and 7 formulas (π/6ABC, 1/2ABC, 1/3ABC, 2/3SH, 1/2SH, π/6SH, and 2.5/6ABC). Taking the hematoma volumes mea
