Influence of diet quality on nutritional status of school-aged children and adolescents in Zanzibar, Tanzania.

Background: Malnutrition among young children and adolescents poses a serious health challenge in developing countries which results in many health problems during adulthood. Poor diet quality is known as the root cause of malnutrition which is caused by unhealthy food choices and bad eating habits among young children and adolescents. However, limited evidence is available on diet quality and its association with nutrition status among young children and adolescents in Zanzibar.

Iterative navigation of multipole diagnostic catheters to locate repeating-pattern atrial fibrillation drivers.

Introduction: Targeting repeating-pattern atrial fibrillation (AF) sources (reentry or focal drivers) can help in patient-specific ablation therapy for AF; however, the development of reliable and accurate tools for locating such sources remains a major challenge. We describe iterative catheter navigation (ICAN) algorithm to locate AF drivers using a conventional circular Lasso catheter.

Methods And Results: At each step, the algorithm analyzes 10 bipolar electrograms recoded at a given catheter location and the history of previous catheter movements to determine if the source is inside the catheter loop.

Catheter simulator software tool to generate electrograms of any multi-polar diagnostic catheter from 3D atrial tissue.

Simulations are excellent tools for assessing new therapeutic strategies and are often conducted before implementing new therapy options in a clinical practice. For patients suffering from a heart arrhythmia, the main source of information comes from an intracardiac catheter. One of the common catheters is a Lasso multi-pole diagnostic catheter, which is a catheter that has 20 electrodes in a circular pattern.

A novel catheter-guidance algorithm for localization of atrial fibrillation rotor and focal sources.

Locating atrial fibrillation (AF) focal and rotor sources can help improve target ablation therapy for AF. However, it remains unclear how to use the information provided by multi-polar diagnostic catheters (MPDC) to locate AF sources. Our aim was to develop a catheter-guidance algorithm to locate AF focal and rotor sources using a conventional MPDC.

Development of a novel probabilistic algorithm for localization of rotors during atrial fibrillation.

Atrial fibrillation (AF) is an irregular heart rhythm that can lead to stroke and other heart-related complications. Catheter ablation has been commonly used to destroy triggering sources of AF in the atria and consequently terminate the arrhythmia. However, efficient and accurate localization of the AF sustaining sources known as rotors is a major challenge in catheter ablation.

[High performance liquid chromatography and radioimmunoassay in analysis of serum hydrocortisone concentration and pharmacokinetic parameters of glucocorticoids in human. The choice of method for clinical practice].

Serum hydrocortisone concentrations were measured by high performance liquid chromatography (HPLC) and radioimmunoassay (RIA) in 24 children with different diseases and 16 healthy adults. HPLC and RIA proved to be equally sensitive. However the authors recommend HPLC as a reliable, rapid, and ecologically pure method, which is, in addition, selective and economic.

[Regulation of the water-electrolyte balance during neurosurgical operations with balanced anesthesia using sodium oxybutyrate].

Water-electrolyte homeostasis and its basic regulatory hormones have been studied in 36 patients with neurosurgical brain pathology during surgical interventions performed under balanced anesthesia (sodium hydroxybutyrate combined with NLA drugs). The study has revealed 3 types of reactions in hormones regulating water-electrolyte homeostasis: type I--a decrease in vasopressin (VP) concentration and renin-angiotensin-aldosterone system (RAAS) activity; type II--VP increase and RAAS activation; type III--an increase in VP content and RAAS disbalance. It has been shown that type I reaction is accompanied by marked osmotic disturbances.
