Assessment of Vitamin D Sufficiency in Different Age Groups of Children in Türkiye Using the Bhattacharya Method

The relevance of the study of the prevalence and intensity of caries in children of different age groups increases due to the fact that the tasks of modern pediatric dentistry include improving the level of care and prevention of caries and its complications.Aim. The purpose of this study is to assess the prevalence and intensity of caries of temporary and permanent teeth in children and adolescents of different age groups (3–5 years, 6–8 years, 9–11 years and 12–16 years) living in the Solntsevo district of Moscow.Material and methods. The study included 1,725 children of four age groups who underwent a routine dental examination in dental departments of hospitals, preschool and school institutions of the Solntsevo district with registration of the presence of carious cavities, fillings and removed teeth.Results. The prevalence of caries in children of different age groups varies depending on the factors affecting the development of caries. The prevalence and intensity increase during the period of milk bite, then drop sharply by the beginning of the period of tooth change, then gradually increasing by the time the formation of a permanent bite is completed. Most of the children are not sanitized at the time of examination.Conclusion. Preventive measures in preschool and school institutions, the level and nature of dental care for children in the Solntsevo district of Moscow are insufficient, since the increase in caries in children of different age groups of the district exceeds acceptable indicators, as a result of which many of the examined have carious cavities.

To investigate the prevalence of diabetes mellitus (DM) among Uygur children in Hotan Prefecture of Xinjiang, China, as well as the factors influencing the development of DM. The cluster random sampling method was used to select 5 308 children, aged 4-18 years, from the middle and primary schools and kindergartens in Hotan Prefecture of Xinjiang. The survey methods included questionnaire survey and the measurement of height and weight. All subjects were tested for fasting fingertip blood glucose to investigate the prevalence of DM and impaired fasting glucose (IFG). A total of 5 184 valid questionnaires were collected. Fourteen children (0.27%) were found to have DM, among whom 8 had type 1 DM, 2 had type 2 DM, and 4 had unclassified DM. Twenty-nine children (0.56%) were found to have IFG. There was no significant difference in the prevalence rate of DM and IFG between boys and girls (P>0.05). The prevalence rate of DM was 0.18% in the 4-<10 years group, 0.47% in the 10-<15 years group, and 0.07% in the 15-18 years group (P=0.072).The prevalence rate of IFG in the above three age groups was 0.18%, 0.94%, and 0.42%, respectively, with a significant difference among groups (P=0.007). The proportion of family history of DM and the proportion of overweight/obesity in children with DM were significantly higher than those in children without DM (P<0.05), while the proportion of children with DM who preferred coarse grains was significantly lower than that in children without DM (P<0.05). The prevalence of DM and IFG in Uyghur children in Hotan Prefecture of Xinjiang is relatively low. There is no significant difference in the prevalence of DM among children of different genders or age groups, but the prevalence of IFG in children of different age groups is different. A family history of DM, overweight or obesity, and low intake of coarse grains might be associated with the development of DM.

The most impotent condition for the development of preschool children is their interaction with other children. In kindergarten conditions, educational situations often arise in which children of different age groups are involved and, as a result, of different ages. That is, the temporary unification of different kindergarten groups of the same age to solve educational problems. The subject of this study is these educational situations with preschoolers of different ages. The purpose is to characterize the potential of their use in preschool educational organization. The theoretical and methodological foundations of this process and historical prerequisites that can be used in the development of partial educational programs of preschool education for children of different ages are revealed. The empirical experience of the author and teachers of kindergarten № 121, kindergarten № 22 in Lipetsk during 17 years is presented. The purposeful guidance of teachers in educational situations with children of different age groups ensures that the interested and educational needs both younger and older children are respected. The conclusions are formed: the interaction of children of different ages has a positive effect on both groups of children. Older preschoolers learn to make decisions, be independent and responsible. Younger children adapt more easily to kindergarten conditions, learn knowledge faster and develop skills in all educational fields. General recommendations for teachers on the organization of educational situational with children of different age groups in preschool setting have been developed and presented. The authors characterized the potential of using educational situations with preschoolers of different age groups as effective opportunities for organizing the pedagogical process in a preschool educational organization. The results of the study will be of interest primary to teachers-practitioners of preschool educational and students of specialized specialties, as they describe the theoretical provisions of pedagogy in the conditions of real long-term kindergarten work.

Introduction. The article includes a comparative study of phenotypic manifestations of undifferentiated connective tissue dysplasia in children of different age groups with urological and andrological pathology. Material and methods. The trial performed included 214 children aged from 1 month to 17 years with clinical manifestations of undifferentiated connective tissue dysplasia who were treated in the children’s uroandrological department for congenital malformations of the urogenital system. The generally accepted table of external phenotypic markers in scores was used in establishing undifferentiated connective tissue dysplasia . Results. In infants, the most frequent disorders were in ears and skin. In the preschool age, in the majority of cases, craniocephalic abnormalities, pathology of osteo-articular system and ears were met. The trail has revealed that the rate of ocular abnormalities increases with age. Moreover, two or more ocular problems were most common in older children. Anomalies of the oral cavity were diagnosed only in a quarter of infants and were manifested in them by a single sign. In older age groups, oral cavity anomalies were in more than half of the patients, and often they were not isolated. During the survey of senior schoolchildren, it was noted that all children of this age group had this or that disorder in their osteo-articular system, and almost always they were multiple. Conclusion. Somatic manifestations of undifferentiated connective tissue dysplasia are often multiorganic and often have non-specific clinical symptoms. Identification of patterns of formation of uroandrological pathology in patients of different age groups with connective tissue insufficiency will ensure timely prevention and correction of visceral manifestations of dysplasia in children.

BackgroundInguinal hernia repair is a common pediatric procedure. We studied postoperative recovery times in children undergoing laparoscopic inguinal hernia repair with anesthesia induced by fentanyl versus sufentanil.MethodsWe performed a pilot randomized clinical trial between February and December 2022. Eligible children were assigned into two age groups, 2–6 and 6–12 years old groups. Then, children in each age group were randomly assigned into either the fentanyl (2 µg/kg) or sufentanil (0.2 µg/kg) group for anesthesia induction. Baseline characteristics were collected. The primary outcome was the postoperative recovery time, which was recorded as the time period from extubation to a Steward recovery score reaching 6. Secondary outcomes included surgical duration, anesthetic duration, intubation duration, and intraoperative hemorrhage.ResultsThere were 300 children, with 75 children in each group. In the 2–6 years old group, children who received fentanyl had statistically significantly shorter postoperative recovery times than children who received sufentanil (0.9 ± 0.4 versus 1.5 ± 0.3 h, P < 0.001). However, in the 6–12 years old group, children who received fentanyl had statistically significantly longer postoperative recovery times than children who received sufentanil (1.2 ± 0.4 versus 0.8 ± 0.4 h, P < 0.001). Baseline characteristics and secondary outcomes were comparable between two groups.ConclusionsAnesthesia induction with fentanyl or sufentanil resulted in different postoperative recovery times after laparoscopic inguinal hernia repair in children in different age groups. More studies are required to determine the appropriate induction anesthetic in children of different ages.Trial registrationThe study protocol was retrospectively registered online at the Chinese Clinical Trial Registry (registration number ChiCTR2300072177, retrospectively registered on 06/06/2023).

The aim of the study was to evaluate the Moraxella catarrhalis nasopharyngeal carriage prevalence in children of different age groups with a recurrent course of respiratory diseases and perform a comparative analysis of bacterial carriage levels as well as peculiarities of within-year distribution of nasopharyngeal carriage in 2016-2017 years. Bacteriological assessment was performed for 1769 children aged 0 to 14 years old including 1082 children examined in 2016 and 687 children examined in 2017. During the two years of observation the average level of M. catarrhalis carriage for the entire study group was equal to 11.5±0.76%. Nasopharyngeal carriage was detected in children of all age groups with the lowest index in children of 7-14 years (4.1±1.03%) and highest levels of bacterial carriage in children of 2-6 years old (13.8±0.98%). Similarities in distribution of M. catarrhalis nasopharyngeal carriage levels in susceptible age groups were detected during 2016 and 2017 years. The analysis of M. catarrhalis carriage levels dynamics revealed within-year undulation of the index – low levels were detected in February and July and high levels in October and November. The research revealed statistically significant and profound concordance of within-year distribution of M. catarrhalis carriage levels in children during 2016 and 2017 years.

The aim of the work is to study the differences in the severity of negative experiences associated with certain aspects of the internal picture of the disease in children undergoing inpatient treatment for respiratory tuberculosis (RT) and children with leukemia, as well as in different age groups of children with RT. Sampling and methods. The study data are presented on a sample of patients aged 5 to 13 years (N= 42, 9 boys, 33 girls), divided into subgroups of 5—7 years, 8—11 years and 12—13 years. The technique of “Unfinished Sentences” by V.E. Kagan and I.K. Shatts was used. At the first stage, the level of negative experiences was compared between groups of children with RT, with leukemia and healthy children (using data from the I.K. Schatz study), at the second stage — in different age groups of children with RT. Conclusions. The results showed a higher level of negative experiences in the group of children with RT due to the absence of severe symptoms and, as a result, difficulties in understanding the need to stay in the hospital. The factors of negative experience in children of different age groups were revealed. Conclusions are formulated about the need to take into account age-related features and the specifics of the disease when developing psychological support programs.

The purpose of this study was to determine the age wise prevalence of Hepatitis B virus (HBV) in children under five years and to analyze the relative importance of horizontal or vertical transmission. This study included 400 children in the age group of less than five years attending the outpatient department of pediatrics with minor complaints. History of HBV immunization was taken as the exclusion criteria. All the samples were tested for Hepatitis B surface antigen (HBsAg) and anti HBs using commercial ELISA kits. Liver function tests were performed on all the HBsAg positive patients. Hepatits B nucleocapsid antigen (HBeAg) was detected in few HBsAg positive mothers. Overall HBsAg positivity in children below five years was 2.25%. There was no statistically significant difference in HBsAg positivity in the different age groups by chi square test. HBsAg positivity in mothers was 4.25%. However only in three cases the pair of mother and child were both positive for HBsAg. The mean anti HBs positivity in children was 23.75%. There was no statistically significant difference in the anti HBs positivity in different age groups of children. The observation that there is no statistically significant difference in the prevalence of HBV infection (HBsAg and HBs) amongst different age groups of children below five years signifies that a large proportion of HBV infection in children of this age is acquired via vertical transmission. It is also indicated that this mode of disease transmission is responsible for the majority of chronic carriers. Universal immunization of all infants is desirable to decrease the carrier pool and it is inferred from the present study that Hepatitis B immunization should begin at birth to have greater impact.

SUMMARY The paper considers symbolic play in different age groups of children in preschool institutions. Symbolic play was stimulated through two different structured activities and dictation of the preparation and the use of different toys and play materials (i.e. thematic symbolic play and play related to pictorial material). The children's play was videotaped in their home playrooms. The videotapes were analysed by competent observers using Smilansky's scale for assessing dramatic and sociodramatic play. Analysis was aimed at establishing which elements determine the symbolic play of children of different age groups with regard to two different play situations, and how they determine it. At the same time, we wished to set out some critical points which significantly determine the nature and course of symbolic play in different age groups of children in preschool institutions. The research also offers certain applied results, since psychological and educational elements of the analysis of the results can serve as a framework in the search for different options for blending the development and learning of preschool children through symbolic play.

To explore the prevalence of central sleep apnea in different age groups of children with sleep apnea-hypopnea (SAH). A total of 431 children with SAH diagnosed by overnight polysomnography at our Sleep Center were retrospectively studied. They were divided into 3 groups based on their ages: toddler group (1 - < 3 years old), preschool group (3 - < 6 years old) and school group (6 - < 13 years old). The relationship between age and different types of apnea-hyponea index (AHI) was analyzed. And the prevalence of central sleep apnea and sleep structure were compared between the groups. A negative correlation existed between age and central sleep apnea index (r = -0.322, P < 0.01). However, there was no correlation between age and obstructive apnea index (P > 0.05). AHI was similar in different age groups, but the medians of central sleep apnea index for toddler, preschool and school groups were 2.35, 1.50 and 0.90 events/h respectively (all P < 0.01). Sleep structure was similar between the groups (P > 0.05). Central sleep apnea is common in children with sleep disordered breathing. The younger their ages, a higher prevalence of central sleep apnea.

To characterize the clinical features and biochemical status at presentation of diabetic ketoacidosis (DKA) in different age groups of children, and to analyze the outcomes of a certain treatment protocol. We reviewed records of patients with DKA who were admitted to our hospital between January 2007 and December 2010. Patients were divided into three subgroups according to age, and the results were compared between these groups. One hundred thirty-four episodes in 111 patients (64 females, 47 males) were analyzed. Of these 134 episodes, 60% was in patients with new-onset diabetes and 40% was in those with established diabetes. Patients younger than 5 years had lower C-peptide and HbA1c levels than older patients at clinical onset. They were also given more alkali therapy. The initial conscious level was found closely related to plasma osmolality and serum sodium levels. Seven of 11 patients with recurrent DKA were females. No major complication was observed. Our study indicates that younger children are at higher risk for severe metabolic decompensation and require more attention and closer monitoring during treatment. We suggest the use of low-dose insulin in this subgroup of patients with DKA without slowing the correction of acidosis.

Particulate matter with a diameter less than 2.5 (PM2.5) is one of the major threats posed by air pollution to human health. It penetrates the respiratory system, particularly the lungs. In northern Thailand, the PM2.5 concentrations have significantly increased in the past decade, becoming a major concern for the health of children. This study aimed to assess the health risk of PM2.5 in different age groups of children in northern Thailand between 2020 and 2029. Based on the PM2.5 data from the simulation of the Nested Regional Climate Model with Chemistry (NRCM-Chem), the hazard quotient (HQ) was used to estimate the possible risk from PM2.5 exposure in children. In general, all age groups of children in northern Thailand will tend to experience the threat of PM2.5 in the future. In the context of age-related development periods, infants are at a higher risk than other groups (toddlers, young children, school age and adolescents), but adolescents also have a lower risk of exposure to PM2.5, albeit maintaining a high HQ value (>1). Moreover, the analysis of risk assessment in different age groups of children revealed that PM2.5 exposure might indeed affect adolescent risk differently depending on gender, with males generally at a heightened risk than females in adolescence.

Unintentional injury in children is a worldwide public health problem, as it increases the health burden and is a leading cause of death among children. It is important to understand the differences between different age groups of children in regard to unintentional injury, in order to effectively implement child safety education. The present study aimed to determine the current trends of unintentional injury in children, and to identify the differences between different age groups of children with regard to unintentional injury. We identified 1,521 children who attended an 18-month health checkup (18-month group), and 1,368 children who attended a 36-month health checkup (36-month group), between January 1, 2014 and December 31, 2014. The rate of hospital visits associated with unintentional injury was 10.6% (161/1,521) in the 18-month group, and 13.1% (180/1,368) in the 36-month group. In both groups, present/past illness was associated with hospital visits, and in the 36-month group, hospital visits were more common in boys than in girls. The number of unintentional injuries that occurred outdoors was higher in the 36-month group than in the 18-month group. Unintentional injuries resulting from accidental ingestion and falls were more common in the 18-month group, while unintentional injuries resulting from turning over were more common in the 36-month group. In conclusion, the number of hospital visits for unintentional injury might be higher, and the number of preventive actions taken by mothers might be lower, among children attending the 36-month health checkup than among those attending the 18-month health checkup.
