BACKGROUND Autistic spectrum disorders (ASD) are neurodevelopmental disorders that most often have profound impact on a person itself, as well as on parents, caretakers, and family life in whole. Parents of a child with ASD often have higher levels of stress and psychological distress. Aim of this study was to examine the stress sources, its frequency and predictability in parents of children with ASD, in relation to the communication and language skills of their children. SUBJECTS AND METHODS The sample consisted of 80 participants who are parents of children with ASD. The study was conducted using a questionnaire made for this research. Three groups of variables were analyzed: parental stress; child's communication; and child's language variables. Statistical analysis was performed by SPSS and included basic statistical parameters and multiple regression analysis. RESULTS The most common sources of parental stress are caring for the child's future; difficulties of the child with speech, language and communication; difficulties of the child in establishing contact with peers and other persons; and inappropriate behavior of the child (anger, aggression, stereotypical behaviors…). Multiple regression analyses used to determine whether a child's communication and language skills were valid predictors of parental stress showed significance. CONCLUSIONS ASD child's skills like showing gestures; looking, answering, and turning when called by name; making it known when he/she needs help or wants an object; answering simple 'Yes/No' questions; and establishing contact with peers, are valid predictors of some stress sources of the parents. Proper involvement in the development of a child's communication and language skills has numerous benefits, not only for the child, but also for the parental stress recognition and its potential frequency decrease.

Background: Vitamin D3 complexed to deglycosylated vitamin D binding protein (VitD-dgVDBP) is a water-soluble vitamin D dimeric compound (VitD-dgVDBP). It is not clear how VitD-dgVDBP affects circulating monocytes, macrophages, other immune cell systems, including phagocytosis and apoptosis, and the generation of reactive oxygen species (ROS) compared to dgVDBP. Methods: Flow cytometry was used to measure superoxide anion radical (O2*−) levels and macrophage activity in the presence of VitD-dgVDBP or dgVDBP. VitD-dgVDBP was incubated with normal human lymphocytes (nPBMCs), and several clusters of determination (CDs) were estimated. dgVDBP and VitD-dgVDBP apoptosis was estimated on malignant prostatic cells. Results: The macrophage activity was 2.8-fold higher using VitD-dgVDBP (19.8·106 counts) compared to dgVDBP (7.0·106 counts), but O2*− production was 1.8-fold lower in favor of VitD-dgVDBP (355·103 counts) compared to dgVDBP (630·106 counts). The calculated ratio of the radical/macrophage activity was 5-fold lower compared to that of dgVDBP. Only VitD-dgVDBP activated caspase-3 (8%), caspase-9 (13%), and cytochrome-C (11%) on prostatic cancer cells. PE-Cy7-labeled VitD-dgVDBP was found to bind to cytotoxic suppressor cells, monocytes/macrophages, dendritic and natural killer cells (CD8+), and helper cells (CD4+). After 12 h of co-incubation of nPBMCs with VitD-dgVDBP, significant activation and expression were measured for CD16++/CD16 (0.6 ± 0.1% vs. 0.4 ± 0.1%, p < 0.05), CD45k+ (96.0 ± 6.0% vs. 84.7 ± 9.5%, p < 0.05), CD85k+ (24.3 ± 13.2% vs. 3.8 ± 3.2%, p < 0.05), and CD85k+/CD123+ (46.8 ± 8.1% vs. 3.5 ± 3.7%, p < 0.001) compared to the control experiment. No significant difference was found using CD3+, CD4+, CD8+, CD4/CD8, CD4/CD8, CD16+, CD16++, CD14+, or CD123+. A significant decline in CD14+/CD16+ was obtained in the presence of VitD-dgVDBP (0.7 ± 0.2% vs. 3.1 ± 1.7%; p < 0.01). Conclusion: The newly developed water-soluble VitD3 form VitD-dgVDBP affected cytotoxic suppressor cells by activating the low radical-dependent CD16 pathway and seemed to induce apoptosis in malignant prostatic cells.

Background: Autism spectrum disorder (ASD) is a developmental disability, which is a biologically based neurodevelopmental disorder that affects a child’s social interaction and communication skills. Core deficits are identified in two domains: social communication/interaction and restrictive, repetitive patterns of behavior. Children and youth with ASD have service needs in behavioral, educational, health, leisure, family support, and other areas. Autism is a set of heterogeneous neurodevelopmental conditions, characterized by inability to acquire social skills, repetitive behaviors and failure of speech and nonverbal communication development. Objective: To examine frequency, correlation and predictivity of communication and language skills of autistic spectrum disorders (ASD) children and their parents’ emotions. Methods: The sample consisted of 80 participants who are parents of children with ASD. The study was performed using a questionnaire made out for this research. Three groups of variables were analyzed: parental emotions variables; child’s communication variables, child’s language variables. Statistical analysis was performed by SPSS, and included basic statistical parameters and multiple regression analysis. Results: The most common ways of communicate for children with ASD are: Allowing to cuddle; Recognizes familiar faces; and Makes it known when he needs help or wants an item. The most common language forms of children ASD are: Following simple instructions; Understanding connected words/phrases; Pronouncing single words; and Looking at when called by name. Parents of children with ASD expressed the greatest agreement with the following statements: “My child is more demanding than most other children”; “It seems to me that my child is very sensitive and easily upset”; “My child can’t do much of what he’s expected to know to do”, and “I often lack energy.” Conclusion: Parents of children with ASD proved that their children have significant delays in communication and language. Developed communication and language skills of the child with ASD are valid predictors of parents’ emotions/attitudes. Speech and language therapy work focused on developing the ASD child’s communication and language skills can be expected to improve parents’ emotions/attitudes.

Objective This study investigated acoustic and perceptual characteristics of the voice of patients with thyroid gland disorders such as hypothyroidism and hyperthyroidism immediately after the diagnosis was made and six months later, after using drug therapy. Materials and Methods The study includes 20 female outpatients with hypothyroidism and 27 female outpatients with hyperthyroidism. The criterion for the selection of the patients was a thyroid gland disorder medical diagnosis, no history of voice disorders and absence of other possible causes of voice changes. Acoustic, perceptual and aerodynamic parameters were assessed. Acoustic analysis was performed by specific software. Experienced speech and language pathologists made perceptual voice assessment by using grade, roughness, breathiness, asthenia, and strain (GRBAS) scale. Results Significant differences in patients with hypothyroidism were established on parameter amplitude perturbation, jitter and noise-to-harmonics ratio between pretreatment and posttreatment period, in which patients took drug therapy. In group of patients with hyperthyroidism significant difference was noted only on aerodynamic parameter maximum phonation time. There were a significant differences in all perceptual parameters in both groups of patients (p<0.05) in pre and posttreatment, except on grade and asthenia parameter in the group of patients with hypothyroidism and parameter grade was borderline insignificant in the group of patients with hyperthyroidism. Conclusion Voice quality is affected by thyroid disease. Thyroid gland disorders cause minor changes in acoustic voice parameters of patients with hypothyroidism and hyperthyroidism, but perceptual deviations in these patients are especially noticeable.

Introduction: Basic cognitive functions such as: alertness, working memory, long term memory and perception, as well as higher levels of cognitive functions like: speech and language, decision-making and executive functions are affected by aging processes. Relations between the receptive vocabulary and cognitive functioning, and the manifestation of differences between populations of elderly people based on the primary disease is in the focus of this study. Aim: To examine receptive vocabulary and cognition of elderly people with: verified stroke, dementia, verified stroke and dementia, and without the manifested brain disease. Material and Methods: The sample consisted of 120 participants older than 65 years, living in an institution. A total of 26 variables was analyzed and classified into three groups: case history/anamnestic, receptive vocabulary assessment, and cognitive assessments. The interview with social workers, nurses and caregivers, as well as medical files were used to determine the anamnestic data. A Montreal Cognitive Assessment Scale (MoCA) was used for the assessment of cognition. In order to estimate the receptive vocabulary, Peabody Picture Vocabulary Test was used. Results: Mean raw score of receptive vocabulary is 161.58 (+–21:58 points). The best results for cognitive assessment subjects achieved on subscales of orientation, naming, serial subtraction, and delayed recall. Discriminative analysis showed the significant difference in the development of receptive vocabulary and cognitive functioning in relation to the primary disease of elderly people. The biggest difference was between subjects without manifested brain disease (centroid = 1.900) and subjects with dementia (centroid = -1754). Conclusion: There is a significant difference between elderly with stroke; dementia; stroke and dementia, and elderly people without manifested disease of the brain in the domain of receptive vocabulary and cognitive functioning. Variables of serial subtraction, standardized test results of receptive vocabulary, delayed recall, abstraction, orientation and vigilance successfully discriminate studied groups.

Introduction: Aging, as an irrepressible biological process involves a series of physiological and pathological changes. The main aim of this study was to examine the correlation and predictability of receptive vocabulary and cognitive functioning of elderly people with anamnestic variables: chronological age, sex, level of formal education, marital status, years of work and retirement and years spent in an institution for the elderly. Material and Methods: The sample of participants consisted of 120 elderly people, average age was 78 years, placed in institutional care for elderly people in four cities in Bosnia and Herzegovina. It was three groups of variables: anamnestic, receptive vocabulary assessment, and cognitive assessments. A Montreal Cognitive Assessment Scale (MoCA) was used for the assessment of cognitive abilities. In order to estimate the receptive vocabulary Peabody Picture Vocabulary Test (PPVT-III-HR) was used. Results: Results of multiple regression analysis show that part of the variance of receptive language which is explained by the model (anamnestic variables) was 44.0% and of cognitive functioning was 33.7%. The biggest single contribution to explaining the development of receptive vocabulary was given by predictor variable of college education (β = 0.417) then variable university education (β = 0.293), while the smallest single contribution was given by variable secondary education (β = 0.167). The biggest single contribution to explaining the results of tests of cognitive function was given by predictor variable College education (β = 0.328) and variable unskilled (β = -0.229), which has a negative effect on the increase in recent cognitive functioning. Conclusion: Anamnestic variables were valid predictors of receptive vocabulary and cognitive functioning of elderly people. The highest individual contribution was given by variables describing the level of formal education of elderly.

The purpose of this study was to examine the syntactic and morphological skills of children who stutter and compare them with those of their fluent peers. Subjects were 58 children, chronological ages of 10 years and 58 of their fluent peers matched by age and gender. For testing of syntactic and morphological skills, we used questions from the informal test Expressive scale of Bosnian/Croatian/Serbian language, as in Bosnia and Herzegovina there is yet no standardized instrument for testing language skills. The results showed that the subjects were significantly different only in the use of gender of pronouns and their endings, and in the task of using different sentence structures, where the analysis showed that subjects who stutter use more simple sentence structures. On other tasks children who stutter showed slightly weaker syntactic and morphological skills. The results suggest that children who stutter at school age show slight linguistic delay in compare to their peers. We could say that there is a subgroup of children who stutter, whose language skills are within the normal range, but who are slightly behind their peers in certain linguistic domains.
