Risk Factors of Perioperative Brain Injury in Children Under Two Years Undergoing Coarctation Repair.

Background: To investigate clinical manifestations and factors of perioperative brain injury (PBI) after surgical repair of coarctation of the aorta (CoA) combined with other heart malformations under cardiopulmonary bypass (CPB) in children under two years.

Methods: The clinical data of 100 children undergoing CoA repair were retrospectively reviewed between January 2010 and September 2021. Univariate and multivariate analyses were performed to identify factors of PBI development.

A Nomogram to Predict Bacterial Meningitis-associated Hydrocephalus: A Single-Center Retrospective Study.

Objective: We aimed to develop a predictive nomogram for the early detection of hydrocephalus in children with bacterial meningitis.

Methods: This retrospective study was based on data of children with bacterial meningitis admitted to our hospital between January 2016 and December 2020. Risk factors were evaluated using univariate analysis, and the predictive model/nomogram was built using binary logistic analysis.

Evaluating seasonal variations of fecal coliform colonization in Magallana hongkongensis and Crassostrea rhizophorae: A preliminary study of oyster quality grown in Hong Kong aquacultural farms.

The objective of this research is to investigate the spatial and temporal patterns of bacteriological quality in raw oysters sampled from different aquacultural farms located in Aberdeen Typhoon Shelter, Carp Gates, Lau Fau Shan, Ma Wan, and Mui Wo in Hong Kong. Magallana hongkongensis and Crassostrea rhizophorae were collected and analyzed for fecal coliforms. Throughout the 13-month monitoring period, all samples had generally high bacterial loads, ranging from 1.

Developmental characteristics of visual evoked potentials to different stimulation in normal children.

Objective: To determine the developmental characteristics of flash visual evoked potentials (FVEP) and pattern-reversal visual evoked potentials (PVEP) of healthy children.

Methods: The data were collected with a Keypoint Workstation 9033A07; 168 children (2 months-13 years) were tested with FVEP and 101 (4-13 years) were tested with PVEP.

Results: A triphasic waveform with clear components (N2, P2, and N3) was recorded steadily after 1 year, with occurrence rates over 97% at all frequencies.

Seizure Characteristics, Outcome, and Risk of Epilepsy in Pediatric Anti-N-Methyl-d-Aspartate Receptor Encephalitis.

Background: We identified seizure characteristics, long-term outcome, and predictors of persistent seizures in children with anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis.

Method: Data were analyzed from patients with anti-NMDAR encephalitis who presented with seizures at our center between August 2012 and June 2018.

Results: Sixty-two of 86 patients with anti-NMDAR encephalitis experienced seizures.

[B-type natriuretic peptides and subclinical target organ damage in essential hypertensive patients].

Objective: To investigate the relationship between B-type natriuretic peptides (BNP) and subclinical target organ damage in essential hypertensive (EH) patients.

Methods: A total of 317 EH patients were divided into 3 groups according to BNP levels, namely normal (BNP<600 ng/L) group (n=102), moderate (600-883.5 ng/L) group (n=116), and elevated BNP (>883.

Impersonality of the connectivity index and recomposition of topological indices according to different properties.

The connectivity index chi can be regarded as the sum of bond contributions. In this article, boiling point (bp)-oriented contributions for each kind of bond are obtained by decomposing the connectivity indices into ten connectivity character bases and then doing a linear regression between bps and the bases. From the comparison of bp-oriented contributions with the contributions assigned by chi, it can be found that they are very similar in percentage, i.

The application of Kriging and empirical Kriging based on the variables selected by SCAD.

The commonly used approach for building a structure-activity/property relationship consists of three steps. First, one determines the descriptors for the molecular structure, then builds a metamodel by using some proper mathematical methods, and finally evaluates the meta-model. Some existing methods only can select important variables from the candidates, while most metamodels just explore linear relationships between inputs and outputs.

Structural interpretation of the topological index. 2. The molecular connectivity index, the Kappa index, and the atom-type E-State index.

The structural interpretation is extended to the topological indices describing cyclic structures. Three representatives of the topological index, such as the molecular connectivity index, the Kappa index, and the atom-type E-State index, are interpreted by mining out, through projection pursuit combining with a number theory method generating uniformly distributed directions on unit sphere, the structural features hidden in the spaces spanned by the three series of indices individually. Some interesting results, which can hardly be found by individual index, are obtained from the multidimensional spaces by several topological indices.

Structural interpretation of a topological index. 1. External factor variable connectivity index (EFVCI).

The external factor variable connectivity index (EFVCI) is interpreted by mining out the structural features hidden in the space spanned by the EFVCI indices through projection pursuit combining with number-theory net (NT-net) on the unit sphere U(Us). Projection pursuit is concerned with "interesting" projections of high-dimensional data sets to machine-pick "interesting" low-dimensional projections of a high-dimensional point cloud by numerically maximizing a certain objective function or projection index. At first, the optimal EFVCI index reaches to -0.

External factor variable connectivity index.

A new variable index, external factor variable connectivity index (EFVCI), is proposed, in which the atomic attribute is divided into two parts. The innate part is denoted as outer-shell electrons and external part or perturbation by other atoms is represented as summation, multiplied by a variable x, of squared reciprocal matrix of i row (corresponds to atom A(i)). The division of atomic attribute in EFVCI is interpreted by using topological structure.
