ABSTRACT Purpose To determine the variations in average distances between various facial landmarks used to determine the vertical dimension of rest and occlusion among dentulous and edentulous subjects. Besides determining the reliability of these facial measurements against commonly used Chin-Nose distance, this study would also compare the difference between cephalometric landmarks (anterior nasal Spine-Menton) with the Chin-Nose distance (Niswonger's method). Materials and methods To standardize the measurement and minimize errors associated with observer and subject movement, a novel instrument was designed in the form of an apparatus and was named as subject and device stabilizing apparatus (SDSA). One hundred and twenty subjects, in the age group of 30 to 60 years, were selected and divided into two equal groups which were further subdivided into subgroups. Measurements were recorded with the help of a digital vernier that was attached to the apparatus. The various facial measure- ments studied were Pupil-Stomion, Glabella-Subnasion, Pupil-Pupil and Angle-Angle both at rest and in occlusion. These measurements were then compared with Chin-Nose and anterior nasal Spine-Menton distance. Differences between the dentulous and edentulous subjects at rest and at occlusion were noted and statistically analyzed using unpaired ‘t’ test and Karl Pearson correlation coefficient. Results Among the six measurements Chin-Nose, Glabella- Subnasion, Pupil-Stomion and anterior nasal Spine-Menton were closely associated between dentulous and edentulous subjects both at rest and at occlusion. Among all facial and cephalometric measurement the facial parameter of Pupil- Stomion illustrates the least deviation in edentulous (1.318) and dentulous (1.381) subjects at rest, whereas anterior nasal Spine-Menton displays least deviation in edentulous (2.751) and dentulous (1.224) subjects at occlusion. Conclusion The average facial measurements in dentulous subjects were more than measurements in edentulous subjects and among various facial measurements, Pupil-Stomion and anterior nasal Spine-Menton distance can be used clinically as a guide to verify vertical dimension of occlusion.

Background: Diabetes is a global epidemic with serious complication and there is a clear need for paying special attention to self-management as the cornerstone to optimal control of the disease. Objectives: This study aimed to assess the self-management status and its correlation to disease control indicators in people with diabetes. Methods: In a descriptive cross-sectional study, 220 patients were selected from the list of the referred patients available in Lamerd public health network from December 2014 to June 2015. In the first step, data about demographic information and disease control were collected from the patients’ records. In the second step, the self-management status of each patient was assessed by the Diabetes Self-Management Questionnaire developed by Schmitt et al. To analyze the data, independent sample t-test and Pearson correlation coefficient were used. Results: The mean age of the male and female participants was 56.43 ± 13.50 and 56.46 ± 10.49 years old, respectively. The mean duration of the disease was 6.67 ± 4.72 years for men and 7.07 ± 5.30 years for women. Twenty-one (25.9%) men and 60 (43.7%) women had a history of smoking. The results of the Pearson correlation coefficient showed that there was an inverse and statistically significant relationship between diabetes self-management status and weight, body mass index (BMI), waist circumference, glucose tolerance test (GTT), LDL, and cholesterol. The results of the t-test did not show significant differences between the level of HbA1C (HbA1C7) and self-management scores of the patients (P > 0.05). Conclusions: Patients with better self-management status were in a better disease control condition with respect to weight, BMI, waist circumference, GTT, LDL, and cholesterol levels. Special attention to the control and management of LDL, cholesterol, HbA1C, BMI, and blood pressure levels is recommended in planning for these patients.

BACKGROUND Health sciences are steadily developing apps to help people to have a correct lifestyle and, in case of chronic diseases, to help physicians to follow their patients. However, a proper validated tool to evaluate patients’ perception of apps’ usefulness, graphic and comfort to use it still lacks in many languages. At present time, there is an English validated questionnaire called User Version of the Mobile Application Rating Scale (uMARS). OBJECTIVE Aim of the study is to translate and validate uMARS in Italian. METHODS uMARS questionnaire have been translated into Italian by an official translator from English. Then, questionnaire has been administrated to 100 smartphone users to evaluate the same App at time 0 and at time 1 (after 2 weeks). Paired t test, Pearson Correlation Coefficient,Intraclass Correlation Coefficient (ICCs) and Cronbach’s Alpha were used to evaluate Italian uMARS reliability and validity. RESULTS Subjects were 100, 52 male (52%) and 48 females (48%). Mean age was 22.8 (SD: 3.4). All the enrolled subjects answered to all questions both at time 0 and at time 1. Paired t test showed no statistically significant difference for each answer or answers group between time 0 and 1 (P>0.05). In detail, higher variability was observed for question E20, regarding the subjective evaluation of the app: “What is your overall (star) rating of the app?” T0 mean 3.7 (SD: 0.8) vs T1 mean 3.6 (SD:1.0) p=0.089. The lower variability was observed in the Information Section for question D16 “Credibility of source: does the information within the app seem to come from a credible source? “, T0 mean 3.6 (SD:1.1) T1 mean 3.6 (SD: 1.1) p=1.000. Cronbach’s alpha was 0.945, as all patients answered to all questions. Each question was furtherly assessed through Pearson correlation coefficient, which demonstrated high reliability, with significant P (<0.05) and Pearson Coefficients higher than 0.7. Similarly, ICC, which was always higher than 0.750, confirmed an excellent test-rest reliability. CONCLUSIONS Our results allow the validation of uMARS in Italian language and it may become a reliable and useful tool to evaluate health app

LANGUAGE NOTE | Document text in English; abstract also in Chinese. This study aims to investigate the correlation between the 2.4 km Run-Walk Test and the Multi-stage Fitness Test (MST) in measuring aerobic fitness in the National Physical Fitness Award (NAPFA) of Secondary 2 students in Singapore. 187 Secondary 2 students (age 14 years) of a mixed gender secondary school were recruited for the study. Subjects performed the 2.4 km Run-Walk Test and the MST. The VO2 max level obtained from both tests were compared using the Pearson correlation coefficient analysis and Paired-sample t-test. Pearson correlation coefficient analysis shows that the predicted VO2 max from the two tests share a strong positive correlation with r=0.78. However, Paired-sample t-test shows that VO2 max predicted by the 2.4 km Run-Walk test is significantly (t = 13.82, p < 0.05) greater (mean = 36.70 L/min, SD = 4.32) than that predicted by MST (mean = 33.60 L/min, SD = 4.91). Results of the present study suggest that both the MST and 2.4 km Run-Walk test can measure aerobic fitness of 14-year old participants for NAPFA. In unfavourable weather, the MST can replace the 2.4 km Run-Walk Test. Further research can be done to enhance the test setting and environmental factors, as well as to include subjects of other age groups and ethnicities, to obtain a more holistic perspective on the interchangeability of the two tests for NAPFA assessment. 本文旨在探討2.4公里耐力跑與20米每分鐘遞增速度往返跑測驗(簡稱20米往返跑)在新加坡全國體能測驗中測試中二學生 心肺功能的關係。本研究對187名男女同校的中二學生(14歲)進行2.4公里耐力跑與20米往返跑。接著，從這兩項測驗中預測 學生最大吸氧量，採用積差相關係數與相依樣本T鑒定進行檢驗。積差相關係數顯示2.4 公里耐力跑與20米往返跑預測的最大 吸氧量正相關(r=0.78)。相依樣本T鑒定顯示2.4公里耐力跑預測的最大吸氧量顯然(t=13.82,p<0.05) 高於(mean=36.70 L/min, SD=4.32)20米往返跑預測的最大吸氧量 (mean=33.60 L/min, SD=4.91)。研究結果顯示，2.4公里耐力跑與20米往返跑可用於新 加坡全國體能測驗，是測試新加坡中二學生心肺功能的可靠方法。若天氣不佳，20米往返跑可取代2.4公里耐力跑。為了在現有 的基礎上加強實驗的整體設定，以及減少環境因素造成的影響，可以進行更深入調查。其外，也可以從不同年齡和種族背景方面 擴大研究物件，從一個更全面的角度研究並分析這兩種測驗在新加坡全國體能測驗的可替換性。

Introduction: Animal models have been used to understand the pathophysiology of pulmonary hypertension, to describe the mechanisms of action and to evaluate promising active ingredients. The monocrotaline-induced pulmonary hypertension model is the most used animal model. In this model, invasive and non-invasive hemodynamic variables that resemble human measurements have been used. Aim: To define if non-invasive variables can predict hemodynamic measures in the monocrotaline-induced pulmonary hypertension model. Materials and Methods: Twenty 6-week old male Wistar rats weighing between 250-300g from the bioterium of the Universidad del Valle (Cali - Colombia) were used in order to establish that the relationships between invasive and non-invasive variables are sustained in different conditions (healthy, hypertrophy and treated). The animals were organized into three groups, a control group who was given 0.9% saline solution subcutaneously (sc), a group with pulmonary hypertension induced with a single subcutaneous dose of Monocrotaline 30 mg/kg, and a group with pulmonary hypertension with 30 mg/kg of monocrotaline treated with Sildenafil. Right ventricle ejection fraction, heart rate, right ventricle systolic pressure and the extent of hypertrophy were measured. The functional relation between any two variables was evaluated by the Pearson correlation coefficient. Results: It was found that all correlations were statistically significant (p <0.01). The strongest correlation was the inverse one between the RVEF and the Fulton index (r = -0.82). The Fulton index also had a strong correlation with the RVSP (r = 0.79). The Pearson correlation coefficient between the RVEF and the RVSP was -0.81, meaning that the higher the systolic pressure in the right ventricle, the lower the ejection fraction value. Heart rate was significantly correlated to the other three variables studied, although with relatively low correlation. Conclusion: The correlations obtained in this study indicate that the parameters evaluated in the research related to experimental pulmonary hypertension correlate adequately and that the measurements that are currently made are adequate and consistent with each other, that is, they have good predictive capacity.

Objective: Accurate assessment of breast tumor size preoperatively is important for the initial decision-making in surgical approach. Therefore, we aimed to compare efficacy of mammography and ultrasonography in ductal carcinoma in situ (DCIS) of breast cancer. Methods: Preoperative mammography and ultrasonography were performed on 104 women with DCIS of breast cancer. We compared the accuracy of each of the imaging modalities with pathological size by Pearson correlation. For each modality, it was considered concordant if the difference between imaging assessment and pathological measurement is less than 0.5cm. Results: At pathological examination tumor size ranged from 0.4cm to 7.2cm in largest diameter. For mammographically determined size versus pathological size, correlation coefficient of r was 0.786 and for ultrasonography it was 0.651. Grouped by breast composition, in almost entirely fatty and scattered areas of fibroglandular dense breast, correlation coefficient of r was 0.790 for mammography and 0.678 for ultrasonography; in heterogeneously dense and extremely dense breast, correlation coefficient of r was 0.770 for mammography and 0.548 for ultrasonography. In microcalcification positive group, coeffient of r was 0.772 for mammography and 0.570 for ultrasonography. In microcalcification negative group, coeffient of r was 0.806 for mammography and 0.783 for ultrasonography. Conclusion: Mammography was more accurate than ultrasonography in measuring the largest cancer diameter in DCIS of breast cancer. The correlation coefficient improved in the group of almost entirely fatty/ scattered areas of fibroglandular dense breast or in microcalcification negative group.
