ABSTRACT Objetive To determine the percentage of correctness of the Orbital Index (OI) for estimation of sex, ancestry and age in Brazilian skulls. Methods Cross-sectional study of 183 human dry skulls from the southeastern Brazil. A total of 100 skeletons were males and 83 females; of which 36 were aged up to 39 years, 60 aged between 40 and 59 years, and 87 aged 60 years or older. As for ancestry, 103 were from white, 51 mixed race, and 29 black individuals. The OI was calculate by the formula = height/width x 100. The data were submitted to Student’s t test, F (ANOVA), Tukey and Kruskal Wallis tests as well as to discriminant analysis, with a 5% significance level. Results The sample was characterized as mesoseme, with a mean age of 56.62 (±19.97) years. No significant difference was observed (p=0.511) between the OI in females (right: 86.43 ± 6.58 and left: 86.70 ± 5.93) and males (right: 85.78 ± 6.69 and left: 86.37 ± 6.20). There were no significant differences between age, ancestry and the variables analyzed (p>0.05). The right and left orbital widths were significantly dimorphic between sexes (p<0.001). The percentage of correctness of the method for estimation of sex, age and ancestry was found to be 65.6%, 43.7%, and 43.6%, respectively. Conclusions The OI is not an appropriate method for estimation of sex, ancestry and estimation of age in this Brazilian sample. The methodology should be expanded to other population groups so that it can be improved.

Aim: To investigate the percentage of correctness (PC) of the Nasal Index (NI) in human skeletons for determination of sex, ancestry and estimation of age in the Brazilian population. Methods: This was a cross-sectional study of 173 human skulls belonging to the Piracicaba Dental School. 93 skeletons were males and 80 females; 34 were aged up to 39 years, 56 between 40 and 59 years, and 83 60 years or older; 96 were from white individuals, 49 were from mixed-race and 28 from black individuals. High-precision digital caliper was used to measure nasal height (NH=ANS-nasion) and the maximum nasal width (NW) values, which were applied into the formula NI=NW/NHx100. The data were submitted to discriminant analysis and Student’s t test with equal variances, Mann-Whitney, F (ANOVA), Tukey and Kruskal Wallis, 5% significance level. Results: Dominant nasal type in the Brazilian population was the mesorine. Males showed nasal height and width values greater than those of females, with statistically significant differences in all measurements (p≤0.021) and PC of 76.6%. Similar nasal measurements were found regardless of age (p>0.05), with PC of 41.7%. Ancestral analysis revealed that black individuals have greater nasal width (26.35) and nasal index (53.67) than white ones (24.60 and 49.25), while mixed-race individuals showed intermediate values (25.36 and 52.13) (p<0.05). Nevertheless, these measurements presented an estimated PC of 54.3%. Conclusion: The Nasal Index can be better used for sex determination than for estimation of age and ancestry in the Brazilian population, as the latter showed intermediate and low percentage of correctness, respectively.

Background: Obesity is a serious health problem, it increases heart-related diseases and its prevalence continues to increase due to genetic and lifestyle influences. This study aims to evaluate the hematological parameters of obese individuals based on gender in the Omisanjana region of Ado Ekiti, Ekiti state. Nigeria. Materials and Methods: The research is based on a cross-sectional study of obese and non-obese individuals in hospitals. The study was carried out in the Omisanjana area of ​​Ado Ekiti, Ekiti state. Fifty (50) obese individuals and fifty (50) apparently non-obese individuals were recruited as controls and participated in the study. The data are shown in the table and are expressed as mean ± standard deviation, and are analyzed using the Student's t test of the statistical software package for social sciences (SPSS, version 20.0), and the level of significance is established at p≤ 0.05. Results: The results showed no significant difference in PCV (p=0.3783), WBC (p=0.501), LYM (p=0.149), GRAN (p=0.336), MID (p=0.242), ,RBC (p=0.243), HGB (p=0.086), HCT (p=0.323), MCV (p=0.943), MCH p=0.097), MCHC (p=0.922), PLT (p=0.941), when compared between obese individuals and non-obese individuals based on sex respectively. Conclusion: The study showed no statistically significant changes, and it may be because there are no significant changes in the physiological factors and the growth factors of the precursor cells in the bone marrow, so the body mass index (BMI) has no effect on hematological parameters.

Background: Spirometry is an important diagnostic monitoring tool for various lung disorders. Ventilatory function can be assessed by spirometry. Also, we can find whether it is obstructive or restrictive disease. An appropriate technique is essential to ensure accurate results. Spirometry requires proper understanding and cooperation of the patient while doing the test. The objective was to evaluate the efficacy and utility of spirometry data in elderly (>65years) individuals with or without lung diseases.Methods: A hospital based cross sectional study was carried out among 199 subjects who were then divided into 100 controls and 99 cases. Spirometry was carried out among all subjects. The values of spirometry were compared among cases and controls as well as across age and sex groups. Student’s t-test was applied.Results: After studying the spirometric data in elderly population with or without lung disease, there was significant difference between cases and controls as far as pack years of smoking was concerned. There was significant difference in FEV1, FVC and FEV1/FVC between the cases and controls. As the age increased the spirometric values decreased. The spirometry was normal in controls in majority compared to none in cases.Conclusions: Spirometry should be used by all primary care and specialist physicians even in elderly population.

ABSTRACT Objective: to analyze the anxiety level of the mothers of newborns with congenital malformations who were diagnosed in prenatal and postnatal care. Methods: a cross-sectional study with 115 mothers of 117 newborns with congenital malformation admitted to three neonatal units. A questionnaire containing maternal and neonatal variables was used, as well as the Trait-State Anxiety Inventory. Data were analyzed by Student’s t-test and Kolmogorov-Sminorv test. The anxiety level was categorized as low (percentile <25), moderate (25-75) and high (> 75), with a significance level of 5%. Results: most mothers had moderate levels of anxiety. Regarding the diagnosis of the malformation, 57% received the news in the prenatal and 43% in the postnatal period. The anxiety level of those who received the prenatal diagnosis was lower than those who received in the postnatal period, evaluated by the Trait Anxiety Inventory (p = 0.026). Conclusion: mothers of newborns with malformations presented moderate anxiety, and this was higher when the diagnosis was given in the postnatal period. The use of the Trait-State Anxiety Inventory can provide guidance to other studies and to clinical practice.

The aim was to cross-sectionally examine the maxillary arch dimensions in 6-year-old children with cleft lip and/or palate and to compare them with the initial cleft sizes among patients with cleft palate. The study included 89 patients with clefts treated at the Oulu University Hospital. The subjects were divided into three groups: cleft palate, cleft lip, and cleft lip and palate. Study casts were scanned, and the maxillary arch dimensions were examined using a 3D program (3Shape Orthoanalyzer, Copenhagen, Denmark). The statistical methods Student’s t-test and one-way ANOVA were used to compare the means (SD) between the groups. Spearman’s correlation coefficient was used to determine the correlation between cleft severity and maxillary dimensions. A significant difference was found between different initial cleft sizes in terms of distance between the second deciduous molar and the first incisor on the right side. The intermolar width showed a negative correlation with the initial cleft size. The dimensions were shorter for clefts affecting the palate and largest for clefts affecting only the lip. Larger clefts resulted in a shorter maxilla on the right side. Many dimensions became shorter when the initial cleft was larger. Clefts of the palate resulted in smaller maxillas.

ABSTRACT Introduction: Facial skeletal asymmetry is commonly found in humans and its main characteristic is menton deviation. The literature suggests that occlusal and masticatory problems arising from tooth absence could be related to the development of such asymmetries. Objective: The aim of this cross-sectional study was to estimate the prevalence of mandibular skeletal asymmetries and to investigate its association with posterior tooth absences. Methods: Tomographic images of 952 individuals aged from 18 to 75 years old were used. Asymmetry was the analyzed outcome, and it was categorized into three groups according to gnathion displacement in relation to the midsagittal plane (relative symmetry, moderate asymmetry, and severe asymmetry). Patients were sorted by the presence of all posterior teeth, unilateral posterior tooth absence, or bilateral posterior tooth absence. Chi-square test with a significance level of 5% was used to verify the association between posterior tooth absence and asymmetry. Results: Results show relative symmetry present in 55.3% of the sample, as well as the prevalence of 27.3% for moderate mandibular asymmetry and 17.4% for severe asymmetry. Moderate and severe mandibular asymmetries occurred in a higher proportion in patients with unilateral posterior tooth absence. However, there was no statistically significant difference between the analyzed groups (p = 0.691). Conclusions: In this study, mandibular asymmetries did not present any association with the absence of teeth on the posterior area of the arch.

Introduction. For health assessment, beside the data of routine health statistics, it is necessary to include and data obtained by a health survey of the citizens. Objective. The aim of this study was to establish how northern Kosovska Mitrovica adults assess their health and which diseases are most common among the population, as well as to investigate differences in relation to demographic and socioeconomic characteristics, the characteristics of social interaction and health behavior and habits. Methods. The research was conducted as a cross-sectional study conducted on the representative sample of adult citizens in northern Kosovska Mitrovica in 2006. Two hundred-eighteen respondents were included in the survey. In the research we used a questionnaire identical to the Health Survey conducted in Serbia in 2006. The significance of differences in responses about self-rated health and chronic diseases in relation to the characteristics of respondents? responses were determined by X2-test with the significance level of 0.05. Results. Over half of the respondents (54.7%) assessed their health condition as good or very good. There was a significant difference in self-rated health in relation to the respondents? age (?2=202.036; p=0.000), education (?2=72.412; p=0.000), social support (?2=12.416; p=0.015), smoking (?2=11.675; p=0.020) and physical activity (?2=61.842; p=0.000). The leading health problems among the respondents were high blood pressure, rheumatologic diseases of joints, ulcer of the duodenal or gastric ulcer, gall bladder disease and high blood fat. Conclusion. Adult residents of northern Kosovska Mitrovica assessed their health as better than the residents of Serbia without Kosovo and Metohia. The diseases in which stress plays the major role among etiological factors are in the leading position. The obtained data on the population level of specific areas represent the basis in the planning of health education and health promotion activities.

Background: Students are considered part of the capital of each country. Several factors can affect their educational status and, as a result, contribute to their academic failure. The current study seeks to investigate the relationship between students’ academic failure and the affecting factors with the Iranian Educational Ranking of Universities. Methods: This is a descriptive cross-sectional study. The required sample size was calculated using Cochran’s formula. A researcher-made questionnaire with 5 parts was used to collect data. Kruskal Wallis and Spearman’s analysis of variance was used for analysis. The significance level was considered as 0.05. Results: A total of 1215 people participated; 13.7% of students had had an academic failure and 2.0% of them were on academic probation. There was a correlation between university RAD rank and academic failure (r = -0.098 and P = 0.0001) as well as student satisfaction (r = 0.264 – P = 0.0001). There was a significant difference between an academic drop and academic grade in three ranks of university (Pv= 0.0001), and, interestingly, having moved from Rank 1 to 3, having academic grade increases, and having academic failure decreases. Conclusion: According to the findings of this study, the higher ranked the college campus is on the RAD scale, the higher the academic failure rate. For annual assessment of universities, it is proposed that assessment of academic failure and grades be used as a benchmark.
