To analyze expert opinions on the quality of PC in various regions of the Russian Federation to optimize pediatric PC. Materials and methods. This prospective cohort study was conducted in 80 regions of the Russian Federation in October–December 2020. We interviewed 276 chief consultants, top healthcare executives, heads of healthcare institutions, pediatric departments, neonatology departments, and gynecological departments. Results. Respondents reported high quality of PC and equipment in healthcare institutions. However, they also marked limited territorial accessibility and volume of PC. They believe that PC in Russia requires better funding and expansion of home care, medical care in day hospitals and regular hospitals, and improvement of legal protection of patients. Conclusion. PC in the Russian Federation is one of the top priorities in healthcare. Several regulatory documents (including orders No 345n/372n and No 348n, resolution No 813, orders for the Moscow Region No 4-r and No 87-r) have been implemented.

Secondary hemophagocytic lymphohistiocytosis (sHLH) is a potentially fatal complication of systemic juvenile idiopathic arthritis (sJIA) characterized by hyperinflammation and a variety of clinical and laboratory manifestations. This condition is also referred to as macrophage activation syndrome (MAS) in patients with rheumatic diseases, including those with sJIA. In this article, we use the term sHLH. Approximately 40% of sHLH cases are asymptomatic, especially in patients who receive biologicals. Thus, the development of a prognostic model and identification of early sHLH markers in sJIA patients will enable timely initiation of anti-inflammatory and immunosuppressive therapy. Objective. To develop a prognostic model and identify early sHLH markers in sJIA patients. Methods. This study included 100 sJIA patients who were examined and treated in the Department of Rheumatology, National Medical Research Center for Children's Health between August 2010 and May 2021. A total of 114 sHLH episodes were registered among study participants. We analyzed medication history, as well as clinical and laboratory parameters reflecting the activity of sHLH and sJIA as potential early markers of sHLH. Multivariate logistic regression analysis was used to assess the predictive value of these markers for sHLH development. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for each factor to evaluate its significance. Receiver operating characteristic (ROC) curves were constructed to assess the sensitivity and specificity of the model. Results. We analyzed a number of factors as potential early sHLH markers, including medication history (treatment with oral or injectable glucocorticoids (GCs) before sHLH, immunosuppressants (methotrexate, cyclosporine, or leflunomide), and biologicals (tocilizumab, canakinumab, adalimumab, etanercept)), clinical signs (fever, rash, hepatomegaly, splenomegaly, lymphadenopathy, myalgia, hemorrhagic syndrome, central nervous system (CNS) lesions, kidney lesions, lung lesions, heart lesions), and laboratory parameters (hemoglobin, absolute count of red blood cells (RBCs), white blood cells (WBCs), neutrophils, lymphocytes, and platelets, erythrocyte sedimentation rate (ESR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), creatinine, blood urea, c-reactive protein (CRP), ferritin, triglycerides, procalcitonin (PCT), total protein, albumin, blood electrolytes (sodium, potassium, chlorides, iron), coagulation parameters (Quick prothrombin, thrombin time, prothrombin time, international normalized ratio (INR), partial thromboplastin time (APTT), D-dimer, fibrinogen, fibrin monomer, von Willebrand factor, protein S, and protein C).

To assess the incidence and risk factors for NEC in full-term newborns with CHD born in 2019–2021 at the Perinatal Center of Almazov National Research Medical Center. Patients and methods. The article presents an analysis of the frequency and risk factors of NEC in children with CHD born at the Almazov National Medical Research Centre in 2019–2021. In the group of critical and duct-dependent CHD (n = 264), the overall incidence of NEC was 15.9% (42 cases). The frequency of surgical stages of NEC (IIIA) was 1.1% (3 cases). In the preoperative period, there was a trend towards a higher frequency of inotropic therapy in a subgroup of children who subsequently developed NEC. NEC in newborns with duct-dependent CHD developed mainly in the early postoperative period after cardiac surgery. In children with duct-dependent pulmonary blood flow, a higher incidence of NEC after surgery was noted compared to children with duct-dependent systemic blood flow. Conclusion. Risk factors for NEC in the postoperative period were arterial hypotension and hemodynamically significant cardiac arrhythmias.

To evaluate the efficacy of therapy for acute respiratory viral infections (ARVIs) in children with antiviral medications: inosine pranobex (Groprinosin®, Gedeon Richter) and Kagocel (Kagocel®, Niarmedic Pharma LLC) in comparison with symptomatic treatment without etiotropic agents based on clinical and laboratory parameters. Patients and methods. The clinical and laboratory observation was conducted in an outpatient setting in the pre-COVID-19 period between 2018 and 2020. Acute respiratory infections were diagnosed using licensed testing systems by multiplex polymerase chain reaction (PCR) with detection of nucleic acid viral genomes: influenza, rhinovirus, respiratory syncytial virus, metapneumovirus, parainfluenza, seasonal coronaviruses, adenoviruses, and bocavirus). A total of 151 children aged 3 to 15 years were examined and monitored in dynamics, with 78.7% of positive and 21.3% of negative results detected by PCR in the nasopharyngeal and oropharyngeal swabs. The patients were randomized into three groups depending on the antiviral medication prescribed: group 1 (53 children) received Groprinosin®; group 2 (52 children) received Kagocel®; group 3 (control, 46 children) received only symptomatic therapy without antiviral agents. Results. The study demonstrated a significant positive effect in patients in group 1 treated with Groprinosin® (n = 53). At the end of therapy for both mono- and mixed infections, there were 95.8% of negative results (according to PCR diagnosis, that is, the absence of viral genome). In children in group 2 (n = 52) treated with Kagocel®, the absence of viral nucleic acids (NAs) was observed less frequently (in 77.3% of cases). In children in group 3 (n = 46) who did not receive etiotropic antiviral therapy, there were only 40.3% of negative results after the end of treatment, and viral NAs were detected in 59.7% of patients. In this case, a 5-day course of Groprinosin® was prescribed, after which the PCR results became negative in all patients. Therefore, children with recurrent respiratory infections, mixed infections, and herpesvirus infections require longer therapy. Additionally, a high frequency of ARVI complications was noted in group 3 (5 (10.9%) patients, where otitis was observed in 1 case, sinusitis – in 2 cases, bronchitis – in 2 cases), whereas 1 (1.8%) patient taking Groprinosin® had otitis, and 1 (1.9%) patient taking Kagocel® had pneumonia. Conclusion. This study was the first to investigate antibody titers to respiratory viruses in dynamics at 3, 6 and 12 months after the onset of ARVI. It showed that the development of antibodies to respiratory viruses is very unstable and does not occur in all patients. Antibodies almost disappeared by the third month after ARVI and were no longer detectable by the sixth month. After 12 months, patients suffered a new ARVI and developed the corresponding antibodies.

A detailed examination of the features of physical development in this region could help to clarify the general patterns of acceleration or deceleration taking place in this territory of the Russian Federation. Objective. To conduct a comparative analysis of physical development indicators of adolescent boys during puberty in 1970-1990 with similar indicators of 2005-2010. Methods. The physical development of adolescents aged 11-17 years was examined in the mountain, foothill, and plain ecological and geographical zones of the Republic of Dagestan. Results. The physical development of boys aged 11-14 years in all ecological and geographical zones of the Republic of Dagestan in both groups was comparable (p > 0.05). Adolescents in the older age group of 15-16 years (group 1) outperformed their peers (group 2) by an average of 0.6-2.1%. From the age of 16, there was a “crossing” of the centile curves of physical development, and adolescents aged 16–17 years (group 2) already outperformed their peers (group 1) in all ecological and geographical zones of the Republic of Dagestan. This was most evident when comparing the physical development of the boys living in the foothill zone, where this difference was significant at 4.0-7.5% (p < 0.04) when comparing the two age groups (group 1 and 2). Final height by the end of puberty in adolescents in group 1 was in the range of 152.0 ± 2.7 cm and 163.0 ± 1.3 cm and in group 2 – 156.3 ± 0.7 cm and 167.7 ± 0.9 cm. Conclusion.

To improve rehabilitation of infants who received respiratory support at birth. Patients and methods. This prospective comparative study was conducted in the Children's City Polyclinic No 13 of Yekaterinburg and included 131 infants who received different types of artificial lung ventilation (ALV) for some respiratory disorders. All patients were followed up by a pediatrician, neurologist, pulmonologist, and an infectious disease specialist; all of them received appropriate therapy. The experimental group comprised 99 infants who additionally received a course of osteopathic (manual) correction for 8–10 weeks, whereas the control group included 32 infants who received standard therapy only. Patients in the experimental and control groups were matched for all parameters. In addition to chest X-ray, all study participants underwent an assessment of their neurological, somatic, and biomechanical statuses. Osteopathic treatment (4 to 6 sessions lasting 30–40 minutes each) was performed by one osteopathic doctor. Statistical analysis was conducted using the SPSS Statistics.26 software; we calculated Pearson's linear correlation coefficient and used Fisher's exact test and McNemar's test. Differences were considered significant at p < 0.05. Results. Seventy-nine infants (79.8%) initially had both neurological and somatic disorders. Ten patients (10.1%) had either somatic disorders (such as labored nasal breathing, regurgitation, constipation, thermoregulation disorder) or neurological disorders (weather sensitivity, sleep disorders, delayed motor and/or neuropsychiatric development, impaired blood and cerebrospinal fluid dynamics) alone. We identified three groups of major somatic dysfunctions (SDs) in the biomechanical status: local (levels: С0–СI, sternum, thoracoabdominal diaphragm, sacrum); regional (cervical spine–level СII–СVI, laryngopharyngeal complex, lungs, abdominal cavity, skull); and global dysfunction of the dura mater. After treatment, the frequency of all neurological and somatic disorders, as well as the frequency of all SDs reduced in the experimental group (p < 0.001). Pathological changes on chest X-rays (elevated diaphragm, low mobility of the thoracic diaphragm, bullae, pleurodiaphragm atic adhesions, etc.) were detected in 89 patients (67.9%), including 66 infants from the experimental group (66.7%) and 23 infants from the control group (71.8%).

Shadow photography was applied to analyze dynamic characteristics of spraying and the dispersed composition of spray particles. Results. Using a silicone model, we evaluated the dose distribution of the spray inside the nasal cavity. We compared dose distribution of two nasal sprays containing framycetin (Isofra and Tramicent) with full and half-full bottles. Shadow photography was applied to evaluate dynamic characteristics of these sprays, including total duration of spraying, duration of its individual phases, spraying angle, as well as dispersion characteristics, such as average particle size and particle size distributions.

The experiments with a silicone nose model demonstrated that Isofra ensured a larger distribution area inside the nasal cavity compared to Terramycin, which suggests a better coverage of the nasal mucosa with Isofra. Comparison of dynamic spraying characteristics (including duration of spraying phases, spraying angle, and shape of the cone) between Isofra and Tramicent using shadow photography showed that Isofra ensured a more homogenous spraying coverage with fine particles. Comparison of the dispersion composition of the two sprays showed that most of the Isofra dose was sprayed with smaller drops than Tramicent, which indicates a better dispersion of Isofra.
