Background: A well-fitting and comfortable ischial containment socket relies on accurately replicating the transverse plane angle of the ischium and ischial ramus angle, inside the medial socket brim. Prediction of the ischial ramus angle, may provide a way to determine the ischial ramus angle without in vivo measurement. Objectives: To determine the accuracy with which the ischial ramus angle could be predicted and identify which variables contributed significantly to the prediction. Study design: Cross-sectional study. Methods: Computed tomography scans were randomly sampled from a cadaveric database (n = 200). Standard multiple regression models were developed to predict the ischial ramus angle based on pelvic measures. Results: The regression model explained 10.5% of the variance in ischial ramus angle (p = 0.018). The standard error of the estimate was 11.32°. While regression models by sex explained a larger proportion of the variance, the resulting accuracy was not improved. Conclusion: The regression models explained a small proportion of variance in ischial ramus angle. The average error associated with the prediction was too large to accurately predict the ischial ramus angle for use in clinical practice. Contrary to commonly held beliefs, there was no statistically significant difference in ischial ramus angle between sexes. Clinical relevance Prediction of ischial ramus angle does not have sufficient accuracy to be clinically useful, but descriptive data may help clinicians identify casting errors and correct these in a plaster positive, knowing that the average ischial ramus angle was 32.65°±5.59° (relative to mid-sagittal plane) and does not vary between sexes.

A torsional wave (TW) sensor prototype was employed to quantify stiffness of the cervix in pregnant women. A cross-sectional study in a total of 18 women between 16 weeks and 35 weeks + 5 days of gestation was performed. The potential of TW technique to assess cervical ripening was evaluated by the measurement of stiffness related to gestational age and cervical length. Statistically significant correlations were found between cervical stiffness and gestational age ( R 2 = 0.370 , p = 0.0074 , using 1 kHz waves and R 2 = 0.445 , p = 0.0250 , using 1.5 kHz waves). A uniform decrease in stiffness of the cervical tissue was confirmed to happen during the complete gestation. There was no significant correlation between stiffness and cervical length. A stronger association between gestational age and cervical stiffness was found compared to gestational age and cervical length correlation. As a conclusion, TW technique is a feasible approach to objectively quantify the decrease of cervical stiffness related to gestational age. Further research is required to evaluate the application of TW technique in obstetric evaluations, such as prediction of preterm delivery and labor induction failure.

Abstract Background Gaining proficiency in Bharatanatyam dance form necessitates maintenance of different postures for prolonged duration. These repetitive movements place tremendous physical demands on the body at young age and may alter the postural profile of the dancer. The study aimed to evaluate the differences in terms of posture between female Bharatanatyam dancers and age-matched non-dancers. A cross-sectional study was conducted in 40 female Bharatanatyam dancers and 40 age-matched female non-dancers in the age group of 18 to 30 years. Analysis of erect standing posture of dancers and non-dancers was conducted in a reserved environment using a photogrammetric method. Static photographs of the subjects were taken in the sagittal plane. The measurement of the angles of the digitized photographs was performed using KINOVEA 0.8.15 software. Head protrusion angle, cervical lordosis angle, thoracic kyphosis angle, lumbar lordosis angle, and pelvic tilt angle were evaluated. Results There was no significant difference between the dancers and non-dancers with respect to head protrusion angle (p = 0.081), cervical lordosis (p = 0.15), and thoracic kyphosis (p = 0.33). Significant differences were identified between the dancers and non-dancers for lumbar lordosis (p = 0.00) and pelvic tilt (p = 0.00) using independent t test with dancers. Higher values of lumbar lordosis and pelvic tilt were observed in dancers. Conclusion Increased lumbar lordosis and anterior pelvic tilt were observed in Bharatanatyam dancers as compared to non-dancers. Hence, it is vital to establish preventive measures like postural re-education, muscular balance, and flexibility to prevent erroneous postural patterns capable of causing pain and injuries.

Summary. Posture is a feature that allows us to understand the biological, mechanical, mental and emotional functioning of human beings; the positioning of the head on the body meets the physiological requirements of breathing, hearing, vision and balance, and the stimuli to which the children are subjected determine to a great extent the postural balance they will have in adulthood. The aim of the present study was to determine the relationship between the position of the head during the use of electronic devices and bipedal position in the sagittal plane in children aged 6 to 10 years. It is a cross-sectional study of 56 children enrolled in a private school in Bogotá, mean age of 8.2 + 2 years whose participation was voluntary. The position of the child in the sagittal plane and the position of the head during the use of electronic devices were evaluated by means of photographs. Correlation measurements and non-parametric tests were used for comparison of medians. 69% of the participants presented advanced head, the average distance from cervical 1 (C1) to the perpendicular traced (P) in children with head forward was 5 cm. The average flexion of the head during the use of the digital tablet was 30 ° while with the computer it was 20 ° (p = .005). No relationship was found between head positions and posture in the sagittal plane in the sample evaluated; a significant difference was found between head flexion during tablet and computer use.Resumen. La postura es una característica que permite entender el funcionamiento biológico, mecánico, mental y emocional de los seres humanos; el posicionamiento de la cabeza sobre el cuerpo cumple con requisitos fisiológicos de respiración, audición, visión y equilibrio, además los estímulos a los que los niños están sometidos determinan en gran medida el equilibrio postural que tendrán en la edad adulta. El objetivo del presente estudio era determinar la relación entre la posición de la cabeza durante el uso de dispositivos electrónicos y la postura en bípedo en el plano sagital en niños de 6 a 10 años. Se trata de un estudio transversal realizado en 56 niños escolarizados en un colegio privado de Bogotá, edad promedio de 8.2 + 2 años cuya participación fue voluntaria. Se evaluó la postura del niño en el plano sagital y la posición de la cabeza durante el uso de dispositivos electrónicos por medio de fotografías. Se utilizaron medidas de correlación y pruebas no paramétricas para comparación de medianas. El 69% de los participantes presentó cabeza adelantada, la distancia promedio desde la cervical 1 (C1) hasta la perpendicular trazada (P) en los niños con cabeza hacia adelante fue de 5 cm. El promedio de flexión de la cabeza durante el uso de la tableta digital fue de 30° mientras que con el computador fue de 20° (p = .005). No se encontró relación entre las posiciones de la cabeza y la postura en el plano sagital en la muestra evaluada; se encontró una diferencia significativa entre la flexión de la cabeza durante el uso de la tableta y el computador.

Purpose The aims of this study were to characterize hearing symptoms, habits, and sound pressure levels (SPLs) of personal audio system (PAS) used by young adults; estimate the risk of developing hearing loss and assess whether instructions given to users led to behavioral changes; and propose recommendations for PAS users. Method A cross-sectional study was performed in 50 subjects with normal hearing. Procedures included questionnaire and measurement of PAS SPLs (real ear and manikin) through the users' own headphones and devices while they listened to four songs. After 1 year, 30 subjects answered questions about their usage habits. For the statistical analysis, one-way analysis of variance, Tukey's post hoc test, Lin and Spearman coefficients, the chi-square test, and logistic regression were used. Results Most subjects listened to music every day, usually in noisy environments. Sixty percent of the subjects reported hearing symptoms after using a PAS. Substantial variability in the equivalent music listening level (Leq) was noted ( M = 84.7 dBA; min = 65.1 dBA, max = 97.5 dBA). A significant difference was found only in the 4-kHz band when comparing the real-ear and manikin techniques. Based on the Leq, 38% of the individuals exceeded the maximum daily time allowance. Comparison of the subjects according to the maximum allowed daily exposure time revealed a higher number of hearing complaints from people with greater exposure. After 1 year, 43% of the subjects reduced their usage time, and 70% reduced the volume. A volume not exceeding 80% was recommended, and at this volume, the maximum usage time should be 160 min. Conclusions The habit of listening to music at high intensities on a daily basis seems to cause hearing symptoms, even in individuals with normal hearing. The real-ear and manikin techniques produced similar results. Providing instructions on this topic combined with measuring PAS SPLs may be an appropriate strategy for raising the awareness of people who are at risk.

Background: Postpartum depression with a different incidence of 40- 45% in different societies, which it has adverse effects on the health of mothers and their child, given the negative effects of maternal depression and its harmful effects on the baby and the quality of family life. So, this study was performed with the aim to determine postpartum depression and its associated factors in Bandar Abbas city. Materials and Methods: A descriptive cross-sectional study was conducted in 2015 after obtaining consent from mothers by the census. A total of 343 mothers was examined for depression who referred to Bandar Abbas health centers in the 2nd and 4th months after childbirth. The data collection tools included demographic information and Postpartum Depression Edinburgh questionnaires. Finally, the statistical analyses were performed using SPSS (version 22.0) software and data were analyzed using the Independent t-test, Mann Whitney, Chi-square, and Fisher exact tests.Result: Totally, 68 (19.8%) of samples were in the second month and 54 (15.7%) in the fourth month after delivery had postpartum depression. The incidence of depression in the four months was 6.6%. There was a significant difference between depression and income, parental education, father’s use of cigarette and abnormalities of the infant (P <0.001). There was no significant difference between other factors such as gestational age, infant sex, birth weight, unwanted pregnancy, and type of delivery. Conclusion: Regarding the prevalence of this disorder, it seems that postpartum depression screening planning should be considered during child routine care as an essential component, especially for vulnerable groups.

Background and Purpose: Stroke is the second cause of mortality and the leading cause of disability. Using the clinical scale to predict the outcome of the patient play an important role in clinical practice. The Totaled Health Risks in Vascular Events (THRIVE) score has shown broad utility, allowing prediction of clinical outcome and death. Methods: A cross-sectional study conducting on 102 patients with acute ischemic stroke using THRIVE score. The outcome of patient was assessed by mRankin in the day of 30 after stroke. Statistic analysis using SPSS 15.0. Results: There was 60.4% patient in the group with THRIVE score 0 – 2 points having a good outcome (mRS 0 - 2), patient group with THRIVE score 6 - 9 having a high rate of bad outcome and mortality. Having a positive correlation between THRIVE score on admission and mRankin score at the day 30 after stroke with r = 0.712. THRIVE score strongly predicts clinical outcome with ROC-AUC was 0.814 (95% CI 0.735 - 0.893, p<0.001), Se 69%, Sp 84% and the cut-off was 2. THRIVE score strongly predicts mortality with ROC-AUC was 0.856 (95% CI 0.756 - 0.956, p<0.01), Se 86%, Sp 77% and the cut-off was 3. Analysis of prognostic factors by multivariate regression models showed that THRIVE score was only independent prognostic factor for the outcome of post stroke patients. Conclusions: The THRIVE score is a simple-to-use tool to predict clinical outcome, mortality in patients with ischemic stroke. Despite its simplicity, the THRIVE score performs better than several other outcome prediction tools. Key words: Ischemic stroke, THRIVE, prognosis, outcome, mortality

Background: Non-communicable diseases seriously affect public health and socio-economic development of the country due to the high number of people suffering from diseases, being disabled and mortal. However, the proportion of people who recognized themselves a suffering from non-communicable diseases such as hypertension, diabetes and dyslipidemia is not high. For cases that their disease situations have been identified, there are not appropriate treatment and preventive behaviors. Objectives: 1) To determine the proportion of 25 - 84 years old peoplewho identified themselves as suffering from hypertension, diabetes and dyslipidemia. 2) To learn treatment and preventive behaviors in the group of people who identified themselves as suffering from diseases. Methods: A cross-sectional study was conducted with a randomly selected sample of 1600 residents in Thua Thien Hue province. Results: The proportion of people knowing that they are suffering from hypertension, diabetes and dyslipidemia was 29.4%; 3.2% and 7.8% respectively. Among them, the proportion of people who did not treat and treated irregularly accounted for 42.7%; 13.7% and 75.2% respectively; the proportion of people who did not change their lifestyles and dietary habits accounted for 50.1%; 5.9% and 56.8% respectively. Conclusions: The proportion of people who identified themselves as suffering from some non-communicable diseases without appropriate treatment and preventive behaviors is alarming. Interventions are needed to help people realize the importance of treatment and prevention effectively. Key words: Non-communicable diseases, hypertension, diabetes, dyslipidemia

Background: There has been a rapid rise in cases of COVID-19 infection and its mortality rate since the first case reported in February 2020. This led to the rampant dissemination of misinformation and rumors about the disease among the public. Objectives: To investigate the scale of public misinformation about COVID-19 in Basrah, Iraq. Methods: A cross-sectional study based on a 22-item questionnaire to assess public knowledge and understanding of information related to the COVID-19 infection. Results: A total of 483 individuals completed the questionnaire. The most frequent age group was 26–35 years (28.2%); there were 280 (58%) males and 203 (42%) females. Of the participants, 282 (58.4%) were with an education level below the Bachelor’s degree, 342 (70.8%) were married, and 311 (64%) were living in districts in Basra other than the central district. Overall, 50.8% (11.8/ 22 * 100%) of individuals had the correct information regarding COVID-19. There was a significant association between the level of COVID-19 related misinformation and participants’ educational levels and occupation (p <0.05). However, there was no significant difference found across sex, age group, marital state, and area of residence. Conclusions: Misinformation related to COVID-19 is widely spread and has to be addressed in order to control the pandemic. Keywords: COVID-19, misinformation, knowledge, Iraq
