Authors: Račiukaitytė Rūta 
Published: November 2021

The article analyzes investigative journalism in Lithuania in 2015–2020 to determine the particularity of changes in investigative journalism. Until then, only one research on investigative journalism was conducted in Lithuania, indicating that in 2015 there was no investigative journalism as a type of media in Lithuania. Although, investigative journalism is a public control tool aimed at exposing corruption and possible criminal activity.
And in 2015, the first research department was established in Lithuania as part of the structure of the media. The work aims to find out how investigative journalism has changed in Lithuania during the last years 2015-2020 and to single out the essential factors that would allow to evaluate the development of investigative journalism. The article presents the author‘s model of investigative journalism and the peculiarities of the change of investigative journalism in Lithuania. It has been established that the situation of investigative journalism in Lithuania is improving, however, compared to the media systems of Western countries, it remains underdeveloped. The perception of experts on investigative journalism is revealed, the reasons for the formation of structural structures of investigative journalism, Lithuania‘s role in international investigative journalism organizations, representatives of investigative journalism are singled out and their research is carried out, research topics, areas, applied research methods

Published: November 2021

OBJECTIVES
Childhood mortality in sickle cell disease (SCD) has decreased, but the transition period is associated with poor outcomes and higher mortality rates. We analyzed recent US hospitalizations and mortality trends in the transition-aged population and evaluated for differences between patients with and without SCD.

METHODS
Nationwide Inpatient Sample database was used to analyze hospitalizations among individuals aged 16 to 24 years from 2003 to 2017. Diagnoses were coded by using International Classification of Diseases, Ninth Revision, Clinical Modification and International Classification of Diseases, 10th Revision, Clinical Modification. We performed bivariate analyses to assess associations between sociodemographic characteristics and SCD hospitalizations, joinpoint regression analysis to describe mortality rate trends in SCD hospitalizations, and adjusted survey logistic regression to assess associations between patient characteristics and in-hospital mortality among transition-aged SCD and non-SCD-related hospitalizations.

RESULTS
There were 37 344 532 hospital encounters of patients aged 16 to 24 years during 2003–2017; both SCD and non-SCD hospitalizations increased with age. Female patients accounted for 78% of non-SCD and 54.9% of SCD hospitalizations. Although there was a +3.2% average annual percent change in SCD hospitalizations, total SCD in-hospital mortality rates did not have a statistically significant increase in average annual percent change over the study period. Patients with SCD aged 19 to 21 and 22 to 24 were more likely to suffer in-hospital mortality than those aged 16 to 18 (odds ratio = 2.09 and 2.71, respectively); the increased odds in mortality by age were not seen in our non-SCD population.

CONCLUSIONS
Transition-aged hospitalizations increase with age, but SCD hospitalizations have disparate age-related mortality rates. Hospital-based comprehensive care models are vital to address the persistent burden of early adulthood mortality in SCD.

Published: November 2021

BACKGROUND AND OBJECTIVES
The activators of rapid-response (RR) events tasked with recognition of clinical decompensation, initial management, and response activation seldom receive RR training. RR activators often experience negative emotions of “failure to rescue” that can compromise team performance during RRs. We used the logic model framework for development and evaluation of an educational program grounded in self-determination theory for pediatric RR activators.

METHODS
The program unfolded in a large quaternary pediatric hospital to impart knowledge and skills; foster autonomy, competence, and relatedness; and improve participants’ satisfaction with performance in RRs. Logic model–guided inputs-activities-outputs-outcomes-context for program evaluation. Preintervention-postintervention follow-up surveys and interviews generated data to determine outcomes and impact of the program. The evaluation instruments were tested for validity and internal consistency.

RESULTS
Over 4 years, 207 multidisciplinary RR activators were trained. Iterative modifications yielded a workshop that incorporated multiple learning modalities, a standardized learner-centered case bank, formalized evaluation tools, and a database to track participation. Significant improvements in RR-related knowledge, self-efficacy, and self- determination were noted. Workshop evaluation yielded a mean score of 4.85 (0.27) on a 5-point scale. At 6-months follow-up survey and interviews, participants reported application of the knowledge and increased confidence with participation in real-life RR events. The workshop gained traction across the hospital, was associated with improved RR clinical outcomes, and contributed to professional advancement of the educators.

CONCLUSIONS
We successfully implemented a self-determination theory–informed RR training program for pediatric RR activators, and the logic model framework was used to facilitate comprehensive evaluation.
Family Perspectives on Continuous Monitor Use in a Children’s Hospital: A Qualitative Study
Authors: Schondelmeyer Amanda C. , Jenkins Ashley M. , Vaughn Lisa M. , Brady Patrick W. 
Published: November 2021

OBJECTIVES
Alarms from continuous cardiorespiratory and pulse oximetry monitors may contribute to parental anxiety and poor sleep during hospitalization, yet families also may find monitoring reassuring. Our objective was to understand how families perceive the utility, benefits, and harms of continuous monitoring.

METHODS
In this single-center qualitative study, we used semistructured interviews and direct observation. We enrolled families of patients of a variety of ages and clinical diagnoses. We extracted patient demographic information (age, diagnosis) from the health record. Semistructured interviews were recorded and transcribed. Detailed field notes were taken during observations. We used an inductive thematic approach to develop and refine codes that informed the development of themes.

RESULTS
We recruited 24 families and conducted 23 interviews and 9 observation sessions. Respiratory conditions (eg, bronchiolitis, asthma) were the most common reason for hospitalization. The hospitalized children covered a range of ages: &lt;4 weeks (16%), 4 weeks to 6 months (20%), 7 months to 5 years (44%), and &gt;5 years (20%); 55% had previously been hospitalized. Families expressed varying degrees of understanding the utility of monitors and often conducted their own assessments before notifying staff about alarms. Families expected monitoring, including negative effects like sleep disruption, as part of hospitalization. Families perceived the benefit of monitoring in context of previous hospital experiences, often seeing less benefit and worrying less about alarms in subsequent hospitalizations.

CONCLUSIONS
Family members continue to find reassurance from cardiorespiratory monitoring despite evidence that it offers limited benefit outside of the ICU setting. Parental perspectives should be addressed in future deimplementation efforts.
Quantifying Empiric Antibiotic Use in US Children’s Hospitals
Authors: Chiotos Kathleen , D’Arinzo Lauren , Kitt Eimear , Ross Rachael , Gerber Jeffrey S. 
Published: November 2021

OBJECTIVES
Empirical broad-spectrum antibiotics are routinely administered for short durations to children with suspected bacteremia while awaiting blood culture results. Our aim for this study was to estimate the proportion of broad-spectrum antibiotic use accounted for by these “rule-outs.”

METHODS
The Pediatric Health Information System was used to identify children aged 3 months to 20 years hospitalized between July 2016 and June 2017 who received broad-spectrum antibiotics for suspected bacteremia. Using an electronic definition for a rule-out, we estimated the proportion of all broad-spectrum antibiotic days of therapy accounted for by this indication. Clinical and demographic characteristics, as well as antibiotic choice, are reported descriptively.

RESULTS
A total of 67 032 episodes of suspected bacteremia across 42 hospitals were identified. From these, 34 909 (52%) patients were classified as having received an antibiotic treatment course, and 32 123 patients (48%) underwent an antibiotic rule-out without a subsequent treatment course. Antibiotics prescribed for rule-outs accounted for 12% of all broad-spectrum antibiotic days of therapy. Third-generation cephalosporins and vancomycin were the most commonly prescribed antibiotics, and substantial hospital-level variation in vancomycin use was identified (range: 16%–58% of suspected bacteremia episodes).

CONCLUSIONS
Broad-spectrum intravenous antibiotic use for rule-out infections appears common across children’s hospitals, with substantial hospital-level variation in the use of vancomycin in particular. Antibiotic stewardship programs focused on intervening on antibiotics prescribed for longer durations may consider this novel opportunity to further standardize antibiotic regimens and reduce antibiotic exposure.

Authors: Hernandez Christina S. , Monuteaux Michael C. , Bachur Richard G. , Hall Jeanine E. , Chaudhari Pradip P. 
Published: November 2021

OBJECTIVES
We examined trends in resource use for infants undergoing emergency department evaluation for serious bacterial infection, including lumbar puncture (LP), antibiotic administration, hospitalization, and procalcitonin testing, as well as the association between procalcitonin testing and LP, administration of parenteral antibiotics, and hospitalization.

METHODS
We performed a cross-sectional study of infants aged 0 to 60 days who underwent emergency department evaluation for serious bacterial infection with blood and urine cultures from 2010 to 2019 in 27 hospitals in the Pediatric Health Information System. We examined temporal trends in LP, antibiotic administration, hospitalization, and procalcitonin testing from 2010 to 2019. We also estimated multivariable logistic regression models for 2017–2019, adjusted for demographic factors and stratified by age (&lt;28 and 29–60 days), with LP, antibiotic administration, and hospitalization as dependent variables and hospital-level procalcitonin testing as the independent variable.

RESULTS
We studied 106 547 index visits. From 2010 to 2019, rates of LP, antibiotic administration, and hospitalization decreased more for infants aged 29 to 60 days compared with infants aged 0 to 28 days (annual decrease in odds of LP, antibiotics administration, and hospitalization: 0 to 28 days: 5%, 5%, and 3%, respectively; 29–60 days: 15%, 12%, and 7%, respectively). Procalcitonin testing increased significantly each calendar year (odds ratio per calendar year 2.19; 95% confidence interval 1.82–2.62), with the majority (91.1%) performed during 2017–2019. From 2017 to 2019, there was no association between hospital-level procalcitonin testing and any outcome studied (all P values &gt; .05).

CONCLUSIONS
Rates of LP, antibiotic administration, and hospitalization decreased significantly for infants 29 to 60 days during 2010–2019. Although procalcitonin testing increased during 2017–2019, we found no association with hospital-level procalcitonin testing and patterns of resource use.

Published: November 2021

BACKGROUND AND OBJECTIVES
Discharge prescription practices may contribute to medication overuse and polypharmacy. We aimed to estimate changes in the number and types of medications reported at inpatient discharge (versus admission) at a tertiary care pediatric hospital.

METHODS
Electronic medication reconciliation data were extracted for inpatient admissions at The Hospital for Sick Children from January 1, 2016, to December 31, 2017 (n = 22 058). Relative changes in the number of medications and relative risks (RRs) of specific types and subclasses of medications at discharge (versus admission) were estimated overall and stratified by the following: sex, age group, diagnosis of a complex chronic condition, surgery, or ICU (PICU) admission. Micronutrient supplements, nonopioid analgesics, cathartics, laxatives, and antibiotics were excluded in primary analyses.

RESULTS
Medication counts at discharge were 1.27-fold (95% confidence interval [CI]: 1.25–1.29) greater than admission. The change in medications at discharge (versus admission) was increased by younger age, absence of a complex chronic condition, surgery, PICU admission, and discharge from a surgical service. The most common drug subclasses at discharge were opioids (22% of discharges), proton pump inhibitors (18%), bronchodilators (10%), antiemetics (9%), and corticosteroids (9%). Postsurgical patients had higher RRs of opioid prescriptions at discharge (versus admission; RR: 13.3 [95% CI: 11.5–15.3]) compared with nonsurgical patients (RR: 2.38 [95% CI: 2.22–2.56]).

CONCLUSIONS
Pediatric inpatients were discharged from the hospital with more medications than admission, frequently with drugs that may be discretionary rather than essential. The high frequency of opioid prescriptions in postsurgical patients is a priority target for educational and clinical decision support interventions.

Published: November 2021

Double borate Na3ErB2O6 was synthesized by the solid-state reaction. The crystal structure of Na3ErB2O6 was refined by the Rietveld method: P21/c, a = 6.49775(14) Å, b = 8.50424(17) Å, c = 12.0067(3) Å, β = 118.4797(9)°, Z = 4. The crystal structure of Na3ErB2O6 consists of –[ErO6]∞-chains along the "b" axis, which are linked by BO3 triangles in a three-dimensional framework. Sodium atoms occupy empty positions inside the channels. The thermal behavior of Na3ErB2O6 was studied in detail in the range of 25–1150 °C range by DSC and TG methods. Na3ErB2O6 congruently melts at 1116 °C. Based on the results of DSC measurements, three reversible phase transitions were found for Na3ErB2O6.

Aim. To study the associations of angiotensinogen (AGT) (s4762(С521Т), rs699(Т704C)) and angiotensin II receptor type I (AGTR1) (rs5186(A1166C)) genetic polymorphisms with serum levels of insulin, glucagon, C-peptide, leptin, as well as with dyslipidemia and glycemic levels in Dagestan residents with combination of type 2 diabetes (T2D) and hypertension (HTN), as well as with isolated T2D/HTN.Material and methods. We examined 16 patients with isolated T2D, 59 patients with T2D+HTN and 51 patients with isolated HTN from Dagestan. Genetic polymorphisms of the AGT and AGTR1 genes were studied. The levels of insulin, glucagon, C-peptide, and leptin were studied by enzyme-linked immunosorbent assay (ELISA), while lipid and carbohydrate metabolism — by biochemical methods.Results. In patients with T2D, the association of CC genotype of AGT gene rs4762(С521Т) polymorphism with a leptin decrease was determined, while its CT genotype was associated with an increase in serum level of triglycerides. The TC genotype of AGT gene rs699(Т704C) polymorphism was associated with an increase in leptin, triglyceride and glucose levels. The AA genotype of AGTR1 gene rs5186(A1166C) polymorphism was associated with an increase in insulin and glucose levels, as well as a decrease in leptin level. In patients with a combination of T2D and HTN, CC and CT genotypes of AGT gene rs4762(С521Т) polymorphism was associated with a decrease in glucagon level. The TT genotype of AGT gene rs699(Т704C) polymorphism was associated with an increase in insulin, triglyceride, glucose and body mass index (BMI) levels. In isolated HTN, the CC and CT genotypes of AGT gene rs4762(С521Т) polymorphism were associated ith a decrease in glucagon level. The TT genotype of AGT gene rs699(Т704C) polymorphism was associated with increased levels of insulin, low density lipoproteins, and BMI.Conclusion. Associations of AGT (s4762(С521Т), rs699(Т704C)) and AGTR1 (rs5186(A1166C)) genetic polymorphisms with carbohydrate and lipid metabolism changes are an important pathogenetic link of T2D and HTN, which allows developing an individual prognosis of these diseases in Dagestan residents.

Aim. To identify the proportion of restrictive cardiomyopathy (RCM), as well as cardiomyopathy (CMP) with a restrictive type of hemodynamics among all cases of genetic CMP and to determine the relative frequencies and spectrum of nucleotide variants in Russian children with RCM, as well as to search for phenogenotypic correlations.Material and methods. The study included 689 children with CMPs. All children underwent a molecular genetic testing of the target regions of 419 genes responsible for various cardiomyopathies and channelopathies using the method of massively parallel sequencing (MPS).Results. In 668 (97,0%) children, pathogenic, likely pathogenic nucleotide variants, as well as nucleotide variants with unknown clinical significance, were identified. Of these, 45 (6,7%) patients were selected to determine the molecular genetic characteristics of RCM, 20 of whom had clinical symptoms and morphofunctional structure of RCMP (3,0%), while the remaining 25 (3,7%) children were diagnosed with another CMP type with a restrictive type of hemodynamics. In total, these patients had 41 nucleotide variants in 15 different genes, while 19 (46,3%) variants were pathogenic, 12 (29,3%) — likely pathogenic, 10 (24,4%) — uncertain clinical significance. Pathogenic and likely pathogenic variants were identified in a total of 38 (84,4%) patients, while in 19 (42,2%) patients, the pathogenic variants described earlier were found. The most common genetic marker of RCM in Russian children was TNNI3 gene mutations. In total, they were identified in 12 (25%) children: with RCP — 8 (40%) patients; with CMP with a restrictive type of hemodynamics — 4 (16%) patients. At the same time, the most common mutation of the TNNI3 gene was the nucleotide variant c.575G>A, leading to the amino acid variant p.R192H, described earlier in patients with RCM and identified by us in three (15%) unrelated children with RCM. In addition, a significant difference was found between the averaged values of N-terminal pro-brain natriuretic peptide in patients with mutations in the MYH7 and TNNI3 genes (0,0039, p<0,05), as well as between the peak flow gradient values in children with mutations in TNNI3 and FLNC genes (0,0016, p<0,05), TNNI3 and MYH7 genes (0,039, p<0,05).Conclusion. The results of this study indicate a significant genetic heterogeneity of RCM in Russian children and the need for further research aimed at finding genotype-phenotype associations in order to predict the course of the disease and select the proper therapy.

Published: November 2021

Aim. To study the diagnostic significance of genetic testing in patients with dilated cardiomyopathy (DCM), identify predictors of life-threatening ventricular tachyarrhythmias (VTAs) and assess adverse clinical outcomes in different genetic groups.Material and methods. The study included 126 unrelated patients with verified DCM as follows: 70 (55,6%) probands with criteria for familial DCM and 56 (44,4%) individuals with a probable hereditary component. All patients (age, 43,1±11,3 years; men, 92 (73%); left ventricular ejection fraction, 30,6±8,43%; left ventricular enddiastolic diameter, 68,3±8,36 mm; follow-up period — median, 49 months) receive a complex of diagnostic investigations, including genetic screening using nextgeneration sequencing, followed by verification of variants by the Sanger method.Results. Pathogenic and likely pathogenic genetic variants were found in 61 (48,4%) of 126 patients with DCM. The dominant mutations were titin-truncating variants (TTNtvs), identified in 16 individuals (12,7%), and variants of lamin A/C (LMNA), identified in 13 probands (10,3%). Mutations in the other 19 genes were found in 32 (25,4%) patients. The following primary endpoints were assessed: sudden cardiac death (SCD), episodes of VTA (sustained ventricular tachycardia/ventricular fibrillation) and appropriate shocks of implanted cardiac resynchronization therapy (CRT)/cardioverter defibrillators (CVD) devices. As a result of ROC analysis, the following independent risk factors for SCD were identified: mutations in the LMNA gene (AUC, 0,760; p=0,0001) and non-sustained ventricular tachycardia (cut-off heart rate ≥161 bpm: AUC, 0,788; p=0,0001). When comparing the phenotypes and genotypes of DCM, TTNtv genotype was associated with a lower prevalence of complete left bundle branch block (χ2=7,46; p=0,024), a lower need for CRT/CVD implantation (χ2=5,70; p=0,017) and more rare episodes of sustained ventricular tachycardia/ventricular fibrillation (χ2=30,1; p=0,0001) compared with LMNA carriers. Kaplan-Meier analysis showed the worst prognosis in carriers of LMNA mutations both in relation to life-threatening VTA (log rang χ2=88,5; p=0,0001) and in achieving all unfavorable outcomes (χ2=27,8; p=0,0001) compared with groups of genenegative individuals, carriers of TTNtv and other genotypes.Conclusion. The phenotypes of DCM with TTNtv did not significantly differ in the incidence of VTAs and adverse outcomes compared with the gene-negative group and other genotypes (with the exception of LMNA). The contribution of the associations of LMNA mutations with VTAs on prognosis was confirmed, which shows the important role of LMNA genotype diagnosis for SCD risk stratification in patients with DCM.
