Patient Capacity

Background.Analysis of medical care delivery for children with cancer in armed conflict is highly important because the high-tech treatment in this context is extraordinary difficult and challenging task. Objective. Our aim was to analyze the morbidity and mortality rates in children with malignant tumors, to assess the pediatric patient capacity and medical service density in the Donetsk People’s Republic.Methods.The ecological study was conducted where the units of analysis were represented by the aggregated data of the Republican Cancer Registry on the number of primary and secondary patients with malignant and benign tumors, the deceased patients in the DNR in 2014–2017, pediatric patient capacity, and medical service density.Results.The number of pediatric patient capacity for children with cancer was 10 (0.27 per 10,000 children aged 0–17), pediatric patient capacity for children with hematological disorders — 40 (1.37 per 10,000 children aged 0–17). The treatment of children with cancer was performed by 5 healthcare providers: 1 pediatric oncologist (0.02 per 10,000 children aged 0–17), 3 hematologists (0.08 per 10,000 pediatric population aged 0–17), and 1 practitioner who did not have a specialist certificate in oncology. Morbidity rate for malignant neoplasms from 2014 to 2017 decreased by 25% (in 2014 — 9.6 per 10,000 children aged 0–17; in 2017 — 7.2). In the morbidity structure, the incidence proportion of hemoblastoses was 68.4%, brain tumors — 2.6%, other solid tumors — 29%. The death rate due to malignant neoplasms decreased by 37% (in 2014 — 2.7; in 2017 — 1.7).Conclusion.Low levels of the incidence rate and pattern of morbidity indicate defects in the identification and recording of patients. This explains the performance of the bed: low average bed occupancy per year and low turnover. For a reliable analysis of mortality statistical data is not available: in 2014–2015 only the number of in-hospital deceased patients is presented. Limited data is due to the lack of reliable patient catamnesis which is explained by the high rate of population migration.

Capacity Determination

In order to design a sensor material for total antioxidant capacity determination we have prepared silica and silica–titania xerogels doped with iron(III) and modified with 1,10-phenanthroline. Titanium(IV) tetraethoxyde content in the precursors (titanium(IV) tetraethoxyde and tetraethyl orthosilicate) mixtures has been varied from 0 to 12.5% vol. Iron(III) concentrations in sol has been varied from 1 to 100 mM. The increase of titanium(IV) content has led to a decrease in BET surface area and average pore diameter and an increase of micropore surface area and volume, which has resulted in better iron(III) retention in the xerogels. Iron(III), immobilized in the xerogel matrix, retains its ability to form complexes with 1,10-phenanthroline and to be reduced to iron(II). Static capacities for 1,10-phenanthroline have been determined for all the iron(III) doped xerogels (0.207 mmol/g–0.239 mmol/g) and they are not dependent on the iron(III) content. Sensor materials—xerogels doped with iron(III) and modified with 1,10-phenanthroline—have been used for antioxidants (catechol, gallic and ascorbic acids, and sulphite) solid phase spectrophotometric determination. Limits of detection for catechol, gallic and ascorbic acids, and sulphite equal 7.8 × 10−6 M, 5.4 × 10−6 M, 1.2 × 10−5 M, and 3.1 × 10−4 M, respectively. The increase of titanium(IV) content in sensor material has led to an increase of the reaction rate and the sensitivity of determination. Proposed sensor materials have been applied for total antioxidant capacity (in gallic acid equivalents) determination in soft beverages, have demonstrated high stability, and can be stored up to 6 months at room temperature.
