ABSTRACT Cardioviruses cause enteric infections in mice and rats which when disseminated have been associated with myocarditis, type 1 diabetes, encephalitis, and multiple sclerosis-like symptoms. Cardioviruses have also been detected at lower frequencies in other mammals. The Cardiovirus genus within the Picornaviridae family is currently made up of two viral species, Theilovirus and Encephalomyocarditis virus. Until recently, only a single strain of cardioviruses (Vilyuisk virus within the Theilovirus species) associated with a geographically restricted and prevalent encephalitis-like condition had been reported to occur in humans. A second theilovirus-related cardiovirus (Saffold virus [SAFV]) was reported in 2007 and subsequently found in respiratory secretions from children with respiratory problems and in stools of both healthy and diarrheic children. Using viral metagenomics, we identified RNA fragments related to SAFV in the stools of Pakistani and Afghani children with nonpolio acute flaccid paralysis (AFP). We sequenced three near-full-length genomes, showing the presence of divergent strains of SAFV and preliminary evidence of a distant recombination event between the ancestors of the Theiler-like viruses of rats and those of human SAFV. Further VP1 sequencing showed the presence of five new SAFV genotypes, doubling the reported genetic diversity of human and animal theiloviruses combined. Both AFP patients and healthy children in Pakistan were found to be excreting SAFV at high frequencies of 9 and 12%, respectively. Further studies are needed to examine the roles of these highly common and diverse SAFV genotypes in nonpolio AFP and other human diseases.

Abstract Introduction Despite much advancement in medicine, endocrine and metabolic diseases remain an important cause of morbidity and even mortality in children. Objective The present study was planned to investigate the evaluation of hearing that also includes high frequencies, and the presence and degree of vertigo and tinnitus symptoms in pediatric patients diagnosed with endocrine diseases such as type 1 diabetes mellitus (DM), growth hormone deficiency (GHD), obesity, idiopathic short stature, and precocious puberty Methods The present study included a patient group of 207 children patients diagnosed with endocrine disease (95 males, 112 females; mean age 9.71 years old [range 6–16 years old]) and a control group including 55 healthy children who do not have any kind of chronic disease (26 males, 29 females; mean age 9.33 years old [range 6–16 years old]). The subjects underwent a hearing test with frequencies between 250 and 20,000 Hz. The vestibular and tinnitus symptoms were evaluated with the Pediatric Vestibular Symptom Questionnaire. Results Out of 207 patients in the patient group, 5 (2.4%) had hearing loss in pure tones, 10 (4.8%) had it in high frequencies, 40 (19.3%) had tinnitus symptoms, and 18 (8.7%) had vertigo symptoms. A total of 4 out of 207 patients in the study group (1.9%), 2 out of 59 with type 1 DM patients (3.4%), 1 out of 46 with GHD (2.2%), and 1 out of 43 obesity patients (2.3%) had hearing loss, vertigo, and tinnitus symptoms. Conclusions Our results suggest that some childhood endocrine diseases can cause some changes in the inner ear, although the exact cause is unknown. Perhaps, a detailed hearing and balance examination should be a routine in a child diagnosed with an endocrine disease. We think it is necessary to work on more comprehensive patient groups and tests in the future.

Relevance. Morpho-functional changes in peripheral circulation established in type 1 diabetes mellitus correlate with changes in central hemodynamics, allowing the use of microcirculation indicators as diagnostic and prognostic criteria for assessing the degree of functional vascular disorders. Identifcation of microcirculation features of the blood by the method of laser Doppler flowmetry in children with different experience of type 1 diabetes in key age categories.Materials and methods. The study included 67 children with type 1 diabetes mellitus aged 12-15 years with an experience of the disease from six months to ten years. The comparison group consisted of 38 healthy children. The state of the microvasculature was assessed by laser Doppler flowmetry using a laser analyzer for capillary blood flow LAKK-OP.Results. In children with an experience of type 1 diabetes of less than two years, microcirculation disorders in periodontal tissues correspond to the hyperemic form, accompanied by increased perfusion, a decrease in the amplitude of low-frequency oscillations, increased heart rate, high blood flling, and blood flow bypass. For children with an endocrinopathy experience of more than three years, microcirculation disorders correspond to a stagnant form, combined with a decrease in perfusion due to stagnation of blood in the venular link, endothelial domination with suppression of neurogenic and cardiac fluctuations, low efciency and redistribution of blood flow in favor of the nutritive link.Conclusions. With the increase in experience, the degree of compensation of type 1 diabetes, the progression of diabetic microangiopathy, it is advisable to designate two stages of development of microcirculatory disorders. Early – compensatory with active adaptation, including neurogenic and endothelial regulation mechanisms. Late – decompensation with passive adaptation, supporting the effectiveness of microcirculation due to myogenic control of regulation, shunting and increasing the rate of blood outflow.

Abstract Objectives There are several hypotheses on the effects of the rs1738074 T/C single nucleotide polymorphism in the TAGAP gene; however, there has been no study on Turkish pediatric patients. We aimed to investigate the association of celiac disease (CD) and type 1 diabetes mellitus (T1DM) comorbidity with the polymorphism in the TAGAP gene of Turkish pediatric patients. Methods Totally, 127 pediatric CD patients and 100 healthy children were included. We determined the polymorphism by the allele-specific polymerase chain reaction method. We used IBM SPSS Statistics version 25.0 and Arlequin 3.5.2 for the statistical analyses. The authors have no conflict of interest. Results It was determined that 72% (n=154) of only CD patients had C allele, whereas 28% (n=60) had T allele. Of the patients with celiac and T1DM, 42.5% (n=17) and 57.5% (n=23) had T and C alleles, respectively. Of the individuals in control group, 67% (n=134) had C allele, whereas 33% (n=66) had T allele. Conclusions There was no significant difference in the genotype and allele frequencies between the patient and control groups (p>0.05). There was no significant association between the disease risk and the polymorphism in our study group.

Flow Mediated Dilatation

Type 1 diabetes (T1DM) is a strong risk factor for the development of cardiovascular disease. Flow-mediated dilatation (FMD) is an early noninvasive marker of endothelial function and it predicts future cardiovascular disease. However, the changes in FMD among T1DM children are still controversial. The present meta-analysis aimed to investigate whether FMD is impaired in children with T1DM. PubMed, EMBASE, Cochrane library, and Web of Science were searched for studies comparing FMD in children with T1DM and healthy controls. The Newcastle-Ottawa quality assessment scale for case–control studies was used to assess study quality. Data were pooled using a random effects models to obtain the weighted mean differences (WMD) in FMD and 95% CIs. Overall, 19 studies with 1245 patients and 872 healthy controls were included in this meta-analysis. Children with T1DM had significantly lower FMDs compared with healthy controls (WMD: −2.58; 95% CI: −3.36 to −1.81; P < .001). Meta-regression analysis revealed that low-density lipoprotein cholesterol levels impacted the observed difference in FMD between T1DM and healthy children. This meta-analysis showed that T1DM children have impaired endothelial function, which indicates they are at higher risk of developing cardiovascular disease in later life.

Picornaviruses infecting pigs, described for many years as ‘porcine enteroviruses’, have recently been recognized as distinct viruses within three distinct genera (Teschovirus, Sapelovirus and Enterovirus). To better characterize the epidemiology and genetic diversity of members of the Enterovirus genus, faecal samples from pigs from four provinces in Vietnam were screened by PCR using conserved enterovirus (EV)-specific primers from the 5′ untranslated region (5′ UTR). High rates of infection were recorded in pigs on all farms, with detection frequencies of approximately 90 % in recently weaned pigs but declining to 40 % in those aged over 1 year. No differences in EV detection rates were observed between pigs with and without diarrhoea [74 % (n = 70) compared with 72 % (n = 128)]. Genetic analysis of consensus VP4/VP2 and VP1 sequences amplified from a subset of EV-infected pigs identified species G EVs in all samples. Among these, VP1 sequence comparisons identified six type 1 and seven type 6 variants, while four further VP1 sequences failed to group with any previously identified EV-G types. These have now been formally assigned as EV-G types 8–11 by the Picornavirus Study Group. Comparison of VP1, VP4/VP2, 3Dpol and 5′ UTRs of study samples and those available on public databases showed frequent, bootstrap-supported differences in their phylogenies indicative of extensive within-species recombination between genome regions. In summary, we identified extremely high frequencies of infection with EV-G in pigs in Vietnam, substantial genetic diversity and recombination within the species, and evidence for a much larger number of circulating EV-G types than currently described.

Esterified Fatty Acids

Composition and quantitative content of non-esterified fatty acids (NEFA) were investigated in plasma samples of healthy children (12) and children with type 1 diabetes mellitus (DM1) (31) by gas chromatography (GC) after preliminary NEFA solid-phase extraction from plasma lipids. There was a significant (p<0.001) 1.6-fold increase in the total level of NEFA regardless of the disease duration. In the group of DM1 children with the disease period less than 1 year there was an increase in the arachidonic acid (20:4) content (30%) and the oleic acid trans-isomer (18:1) content (82%), and also a decrease in the docosahexaenoic acid (22:6 n3) content (26% ) and the docosapentaenoic acids (22:5 n-6) content (60%). In the group of DM1 children with prolonged course of this disease the altered NEFA levels returned to the normal level
