The effect of serum biochemical parameters on clinical prognosis in children presenting with diabetic ketoacidosis.

Objective: The aim of this study was to determine whether diabetes mellitus has a high risk of diabetic ketoacidosis-related complications. Biochemical parameters affect the resolution time of diabetic ketoacidosis.

Methods: The present study is based on a retrospective evaluation of the records of patients who presented to the Pediatrics Clinic of Adiyaman University Hospital between January 1, 2017, and October 1, 2022, with a diagnosis ofdiabetic ketoacidosis.

Further Evidence for Gene Causing Fanconi Anemia Complementation Group W: Detailed Clinical Report of the Second Case in the Literature.

Introduction: Fanconi anemia (FA) is a heterogeneous genetic disorder that is characterized by progressive bone marrow failure, congenital malformations, predisposition to malignancy, and short stature. The gene was recently associated with FA complementation group W, and only 1 patient is reported in the literature so far.

Case Presentation: Here, we report the second patient, a 10-year-old male, who has failure to thrive, central nervous system abnormalities, bilateral radial ray defects, urogenital anomalies, facial dysmorphism, and thrombocytopenia.

Impact of the Age at Distal Hypospadias Surgery on Behavioral Problems, Somatic Symptoms and Irritability Levels in Children.

Background: To assess the effect of age at hypospadias surgery on emotional and behavioural problems, somatic symptoms, irritability, and penile perception.

Methods: We retrospectively identified the patients who underwent single distal hypospadias surgery and age-matched healthy controls were included. There were two further subgroups according to the age at the time of hypospadias repair (<2 vs.

Real-time nonlinear parameter estimation and tracking control of unmanned aerial vehicles in closed-loop.

The real-time unknown parameter estimation and adaptive tracking control problems are investigated in this paper for a six degrees of freedom (6-DOF) of under-actuated quadrotor unmanned aerial vehicle (UAV). A virtual proportional derivative (PD) controller is designed to maintain the translational dynamics. Two adaptive schemes are developed to handle the attitude dynamics of the UAV with several unknown parameters.

A case of familial recurrent 17q12 microdeletion syndrome presenting with severe diabetic ketoacidosis.

Background: Heterozygous intragenic mutations of the hepatocyte nuclear factor 1 homeobox b gene (HNF1B) located on chromosome 17 and microdeletion of 17q12 region (17q12MD) leads to the complete loss of this gene, which causes renal cystic disease, diabetes mellitus (MODY5), hypomagnesemia, hyperuricemia, liver enzyme abnormalities, genital tract abnormalities and exocrine pancreatic insufficiency. In addition, patients with 17q12MD also have facial dysmorphism, neuro-developmental and neuropsychiatric disorders.

Case: A 16-year-old girl with obesity and mild facial dysmorphism was admitted to the hospital with symptoms of diabetes that started two days prior to her admission.

Increased Severe Cases and New-Onset Type 1 Diabetes Among Children Presenting With Diabetic Ketoacidosis During First Year of COVID-19 Pandemic in Turkey.

Introduction: There have been some significant changes regarding healthcare utilization during the COVID-19 pandemic. Majority of the reports about the impact of the COVID-19 pandemic on diabetes care are from the first wave of the pandemic. We aim to evaluate the potential effects of the COVID-19 pandemic on the severity of diabetic ketoacidosis (DKA) and new onset Type 1 diabetes presenting with DKA, and also evaluate children with DKA and acute COVID-19 infection.

Reversible Calcium(II)-Ion Binding through an Apparent pKa Shift of Thermosensitive Block-Copolymer Micelles.

There is an increasing need for smart materials capable of removing multivalent ions from aqueous streams without the inconvenience of brine regeneration as in ion-exchange processes. Herein, we present a thermoresponsive micellar system consisting of polystyrene-poly(methoxy diethyleneglycol acrylate) block copolymer surfactants modified with carboxylic acid end groups (PS-PMDEGA-COOH) that can be used to switch between the adsorption and desorption of divalent calcium(II) cations by a mild temperature trigger, thus providing a new type of thermoregenerable ion-adsorbing materials. The switch of calcium(II)-binding capacity is demonstrated to result from a shift in the pKa value of the carboxylic acid groups by the collapse and redissolution of the PMDEGA block and the associated change in local polarity.

Self-assembly of double hydrophobic block copolymers in water-ethanol mixtures: from micelles to thermoresponsive micellar gels.

Micellization and micellar gel formation of poly(styrene)-block-poly(methyl methacrylate) [PS-b-PMMA] are demonstrated in a water-ethanol solvent mixture; full hydration of the PMMA causes a large radius of gyration resulting in micellar gel formation at only 1 wt% polymer concentration.
