Comparison of Pulmonary Functions, Physical Activity Level and Quality of Life in Obese and Pre-Obese Individuals

Objective: There are studies regarding pulmonary functions of obese individuals in literature; however, there is insufficient data regarding pre-obese individuals. This study aimed to compare the pulmonary functions, physical activity levels, and health-related quality of life (HRQOL) of obese and pre-obese individuals. Methods: The characteristics of 62 subjects participating in the study were recorded All subjects were evaluated using pulmonary function tests (PFT), short form-36 health survey (SF-36), obesity and weight loss quality of life measure (OWLQOL), international physical activity questionnaires (IPAQ), and modified medical research council (mMRC) scale. Results: The severity of perceived dyspnea in obese subjects was significantly higher than that in pre-obese subjects. The PFT parameters (FVC, FEV1, PEF, FEF25–75, FEF25–75%, MVV, and MVV%) were significantly lower in obese subjects. Although individuals in both groups were inactive, the inactivity levels in obese subjects were significantly higher. HRQOL scores were significantly lower in obese individuals. The body mass index (BMI) was significantly correlated with dyspnea severity, SF-36 subscores, OWLQOL scores, and PFT parameters. Conclusion: While an increasing BMI has an adverse effect on the pulmonary functions of pre-obese individuals, increased BMI coupled with reduced pulmonary functions causes a decrease in the physical activity levels and reduces HRQOL of obese individuals

Does the Panoramic Radiography Have the Power to Identify the Gonial Angle in Orthodontics?

Purpose. The objective of this study was to assess gonial angle under the angle classification by comparing panoramic radiograph and lateral cephalometric radiograph. Materials and Methods. 49 patients (25 males, 24 females) with an age range of 12–29 years participated in the present study. Subjects were retrospectively selected among those categorised as skeletal and dental Class I, II, and III malocclusion group. Using lateral cephalometric radiograph, mandibular and ramal planes were drawn and based on these planes. Gonial angle was determined from two tangents which were drawn from the inferior border of the mandible and posterior borders of the condyle and ramus of both sides in the panoramic radiographs. Multiple comparison tests (ANOVA) were used to determine differences between the three angle groups. Results. There were no significant differences between Class I, II, and III malocclusion group values of gonial angles determined by lateral cephalometric radiograph and panoramic radiographs (). Conclusion. Panoramic radiograph results were shown to be as reliable as lateral cephalometric radiograph in all angle classifications. Panoramic radiography can be used as an alternative radiographic technique to detect gonial angle in orthodontic patients

USEFULNESS OF A NEW PARAMETER IN FUNCTIONAL ASSESSMENT IN PATIENTS WITH IDIOPATHIC PULMONARY FIBROSIS: DESATURATION- DISTANCE RATIO FROM THE SIX-MINUTE WALK TEST

Background and aim: New parameters in the 6-minute walk test (6MWT) are needed for assessing exercise capacity in patients with idiopathic pulmonary fibrosis (IPF). To our knowledge, no previous study has investigated the potential of using the desaturation distance ratio (DDR) to assess exercise capacity specifically in patients with IPF. This study aimed to investigate whether DDR is a potential tool for assessing the exercise capacity of patients with IPF. Methods: This study conducted with 33 subjects with IPF. Pulmonary function tests and a 6MWT were performed. To calculate the DDR, first, the difference between the patient's SpO(2) at each minute and the SpO(2) of 100% was summed together to determine the desaturation area (DA). Next, DDR was calculated using dividing DA by the 6-minute walk test distance (6MWD) (i.e., DA/6MWD). Results: When correlations of 6MWD and DDR with changes (.) in the severity of perceived dyspnea were examined, 6MWD did not significantly correlate with Borg. Conversely, there was a significant correlation between the DDR and Borg (r= 0.488, p=0.004). There were significant correlations between 6MWD and FVC % (r=0.370, p=0.034), and FEV1 % (r=0.465, p=0.006). However, DDR was significantly more correlated with FVC % (r= -0.621, p< 0.001), FEV1 % (r= -0.648, p< 0.001). Moreover, there was a significant correlation between DDR and DLCO % (r= -0.342, p=0.052). Conclusions: The findings of this study suggest that DDR is a promising and more useful parameter for assessing patients with IPF
