A study of sleep and dream characteristics has been carried out by questionnaire on a sample of 77 MZ and 76 DZ same-sex twin pairs of two age groups, 6–8 and 16–18 years. Genetic effects could not be detected in the younger age group and appeared to be rather limited in the older one, possibly as a result of the limited variability of the considered variables and of the levelling influence of the common environment.

Abstract Aims and Objectives: To assess the posed and dynamic smile and to compare the various attributes of smile in frontal, oblique and sagittal dimensions, in two different age groups (10- 15years and 18-25 years). Materials and Methods: The posed and dynamic smile parameters were measured using digital video clips in 80 subjects of two different age groups (10-15years and 18-25 years). Total of 15 parameters were studied in 3 planes of space. The data was analysed using student`s t-test to compare smile parameters across the age groups, paired t-test was used to analyse the parameters of posed and unposed smile within the same age group and chi-square test was performed for the discrete data. Results: The present study revealed significant differences in dynamic smile parameters between the two age groups. The parameters like Philtrum height and Smile index are more in older age group whereas the buccal corridor was more in younger age group. Significant differences were also recorded in various parameters in both the groups when the posted smile is compared with that of the dynamic smile. Conclusion: In both the age groups, the dynamic and posed smile attributes are significantly different, except for buccal corridor and interlabial gap.

ABSTRACTIn order to examine whether children adjust their phonetic speech categories, children of two age groups, five-year-olds and eight-year-olds, were exposed to a video of a face saying /aba/ or /ada/ accompanied by an auditory ambiguous speech sound halfway between /b/ and /d/. The effect of exposure to these audiovisual stimuli was measured on subsequently delivered auditory-only speech identification trials. Results were compared to a control condition in which the audiovisual exposure stimuli contained non-ambiguous and congruent sounds /aba/ or /ada/. The older children learned to categorize the initially ambiguous speech sound in accord with the previously seen lip-read information (i.e. recalibration), but this was not the case for the younger age group. Moreover, all children displayed a tendency to report the stimulus that they were exposed to during the exposure phase. Methodological improvements for adjusting such a response bias are discussed.

Numerous studies show that wide range of anthropological characteristics and health indicators significantly affects the success in football. Therefore, constant monitoring of these indicators provides to the coaches the information useful for the planning of the training process, adjusted to concrete athletes. This study explores selected morphological, physiological characteristics and health (MPH) indicators of adult football players of various levels of sporting excellence. The aim of the study was to determine the differences in MPH indicators, as well as their correlation, stratified according to the age group of the athletes. The different profiles of players were identified, in relation to selected MPH indicators. A sample of 813 male players is examined, 362 in the age group 17-30 years (M±SD 21.48±3.51) and 451 aged over 30 years (43.84±9.17), from Zagreb football clubs, included in medical examination at the Clinic for Occupational Health and Sport. Several differences in MPH are found between two age groups, mainly in direction more desirable features in younger age group. The results provide important information for planning training, but also for health prevention measures.

AbstractBackground:Vestibular schwannomas in younger patients have been observed to be larger in size and grow more quickly.Objective:This study aimed to evaluate the expression of three important cell cycle proteins, cyclin D1, cyclin D3and Ki-67, in vestibular schwannoma patients separated into two age groups: ≤40 years or >40 years.Method:Immunohistochemical detection of cyclin D1, cyclin D3and Ki-67 was undertaken in 180 surgically resected vestibular schwannomas.Results:The proliferation index of vestibular schwannomas was statistically higher in the ≤40 years age group compared to that in the >40 years age group (mean of 4.52vs3.27, respectively;p = 0.01). Overexpression of cyclin D1and cyclin D3was found in 68 per cent and 44 per cent of tumours, respectively.Conclusion:There was an increased Ki-67 proliferation index in the younger age group that appears to correlate with clinical behaviour. Vestibular schwannomas in both age groups show increased expression of cyclin D1and cyclin D3.

Purpose:to study blood pressure levels and the prevalence of hypertension in persons aged 25–45 years in Novosibirsk.Materials and methods.A cross-sectional population study in one of typical areas of Novosibirsk was performed in 2013–2016. The study included 479 men and 612 women aged 25–45 years. Arterial hypertension was defined as blood pressure (BP) ≥140 / 90 mmHg according to Russian recommendations (2004). For analysis two age groups were distinguished: 25–34 years and 35–45 years.Results.Mean values of systolic and diastolic BP were significantly lower in women than in men in age groups. In men and women, the analyzed indicators were significantly higher in the older than in the younger age group. Mean values of pulse pressure in men were significantly higher than in women in both age groups, there were no differences in the analyzed index between age groups in either men or women. Optimal BP was more often recorded among women than among men in both age groups. The proportion of persons with normal BP among men was grate than among women in both age groups. In the age group 35–45 years compared with the younger group, in men there was a decrease in incidence of category with BP<140 / 90 mmHg, an increase of the proportion of persons with hypertension grades 1 and 2, the appearance of persons with grade 3 hypertension; in women – an increase of the proportion of individuals with normal, high-normal BP, and with grade 1 hypertension, appearance of individuals with grades 2 and 3 hypertension. Frequency of BP categories ≥140 / 90 mmHg in age group 25–34 years among men was 17.6 %, among women 3.1 % (p<0.0001); in age group 35–45 years among men – 34.7 %, among women – 12.5 % (p<0.0001).Conclusions.Prevalence of hypertension in men was 28 %, in women – 9 %. Favorable tendencies of BP indicators in both sexes were revealed over a 30-year period, while gender differences did not change.

Introduction: Epistaxis is a common problem which may affect all age groups. It has bimodal presentation.Nontraumatic epistaxis may affect more frequently among older male. Objective: It is important to observe the common factors related with the different etiological types of epistaxis. It is also important to observe the various socio demographic characteristic of the patient with pattern of presentation of the epistaxis. Mehods: Cross-sectional study in tertiary level hospital. From July 2012 to June 2013, 176 participants were selected. Results: Traumatic epistaxis was more frequent (70.51%) among younger age group (age <45yeras), whereas non-traumatic epistaxis was more frequent (72.92%) among older age group (age >45yeras). There was a statistically significant difference between the different age group with their etiology of the epistaxis (P = <0.001). Bangladesh J Otorhinolaryngol; April 2017; 23(1): 32-40

Abstract Objective: To estimate the prevalence of periodontal disease with different indices. Methods & materials: The study population consisted of multistage stratified random sample of 1300 subjects from total population of district Ghaziabad. A cross-sectional study was conducted with multi stage stratified random sampling techniques to select the sample population. The subjects were divided into different age groups and the periodontal assessment was made on the basis of CPITN index and ESI Index. Results: The CPITN has shown to estimate incorrect periodontal disease prevalence because of its underestimation of the disease severity. A huge difference was noticed in the prevalence rate of periodontitis when subjects were examined with ESI index. Conclusion Periodontal disease was found to be highly prevalent in the study population and severity of disease increased with age. More number of subjects in younger age group were found to be healthy.

Abstract Background Research on talent in sports aims to identify predictors of future performance. This study retrospectively investigated 1) relationships between young handball field players’ technical throwing skills and (a) their potential nomination to youth national teams and (b) their long-term career attainment 10 years later, and 2) associations between nomination status and career attainment. Results Results from retrospectively predicting nomination status and career attainment using logistic regression analyses show that technical throwing skills were partly able to explain players’ nomination status (Nagelkerke R2: females 9.2%, males 13.1%) and career attainment (Nagelkerke R2: 9.8% for female players). Here, variables throwing velocity and time on exercise showed statistically significant effects. In addition, nomination status and career attainment were shown to be associated using chi-square tests (w of .37 and .23 for female and male players, respectively) and nomination status as a predictor increased the prediction of career attainment remarkably (Nagelkerke R2: females 20.3%, males 12.7%). Conclusions Given these results, basic technical throwing skills may serve rather as a prerequisite in this age group on national level, emphasizing its importance already on lower levels and in younger age groups. Furthermore, advantages from entering the national TID system early especially for females are discussed.

Background: Adipose tissue mainly visceral fat is said to be harmful and acts as a harbinger of metabolic disorders. A changing trend is seen in the recent decades with decreasing incidence of metabolic disorders in men even though visceral fat is said to be higher in them. Sex hormones may influence the deposition pattern of adipose tissue. The aim of this study was to observe effects of age on visceral fat and to know if the difference in gender pattern of fat distribution is maintained throughout life or disappears after menopause.Methods: This cross-sectional observational study was conducted in Thrissur on 385 apparently healthy subjects using Omron body composition analyser. Data was analysed using SPSS 20.0 version. The tests employed were NOVA, independent samples t-test.Results: In each age group, men had significantly higher visceral fat than females. As age increased, visceral fat increased significantly in both genders. In each group, except for younger age groups, VF levels were equal in men and women.Conclusions: Visceral fat is higher in men and this difference is seen in all age groups. As age increases, visceral fat levels also increased in men and women. The distribution of visceral fat is such that a greater number of men have high to very high levels at a younger age group, a feature observed in women only in the peri and post-menopausal age. Adoption of an active lifestyle coupled with healthy diet should protect against onset of metabolic disorders.

Introduction. Burden of HIV in pregnant women follows overall epidemic in India. Hence, it is imperative that prevalence calculations in this group be accurate. The present study was carried out to determine prevalence of HIV in pregnant women attending our hospital, to determine trend of HIV infection and to compare our results with reported prevalence. Methods. All pregnant women are routinely counselled for HIV testing using opt-out strategy. Year-wise positivity and trend were determined in these patients over a period of five years. The positivity in different age groups was determined. Results. 31,609 women were tested of which 279 (0.88%) were positive. Positivity showed a declining trend over study period and significant quadratic trend (biphasic, P<0.05) was observed. The positivity in older age group ≥35 years (1.64%) was significantly more than younger age groups (0.76% in 15–24-year and 0.94% in 25–34-year age group) (P=0.0052). Conclusion. A significant decline in HIV positivity was seen over the study period. Taking into account heterogeneous nature of HIV epidemic even within the same district, analysis at local levels especially using the prevention of parent to child transmission of HIV program data is critical for HIV programming and resource allocation.
