Localization of the Porion Landmark in Orthodontics: A Comparison of the Efficiency of NEMO-Ceph 2020 Software between Inexperienced and Expert Operators

2023 , Loaiza Martinez, Daniela , Llerena-Velasquez S.A. , Gallegos J. , Ferrando R.

This study discusses the utility of the NEMO-Ceph 2020 software in localizing the cephalometric landmark known as the Porion point (Po) and the Frankfurt plane in orthodontics. It highlights the challenges in locating the Porion point due to anatomical variations and external factors. The use of radiographs as a diagnostic method is mentioned, along with the need for new tools to aid in locating the Porion landmark. The study employed a database of 179 teleradiographs from the "UCAM DENTAL"database, processed using NEMO-Ceph 2020® software. Inexperienced operators (4th and 5th-year dentistry students) and an expert operator participated. Linear measurements and angular differences were analyzed using the software. Results revealed discrepancies in the Porion point's location among operators, with mean discrepancies of 2.42 mm (X-axis) and 2.23 mm (Y-axis). The mean discrepancy between Porion points was 2.47 mm, and with the Frankfurt point was 2.44 mm. No statistically significant correlation existed between discrepancies in the X and Y axes. The study concluded that there was a significant difference in Porion point location between inexperienced operators and the expert, and that NEMO-Ceph 2020® software required expert operators for accurate localization of cephalometric landmarks and could not predict the point independently. © 2023 IEEE.

Personalised Nutritional Plan and Resistance Exercise Program to Improve Health Parameters in Celiac Women

2022 , Martínez-Rodríguez, A. , Loaiza Martinez, Daniela , Sánchez-Sánchez, J. , Rubio-Arias, J.Á. , Alacid, F. , Prats-Moya, S. , Martínez-Olcina, M. , Yáñez-Sepúlveda, R. , Marcos-Pardo, P.J.

Celiac disease (CD) is a permanent immune reaction to gluten in those with a genetic predisposition. This study was designed to evaluate menopause-associated symptoms, mood, bone quality, and IgA antibody levels in women with CD, untreated and treated with a gluten-free diet (GFD), and with or without resistance exercise. The randomised controlled trial was conducted on 28 Spanish women (>40 years old). Participants were divided into the following intervention groups: personalised gluten-free nutrition plan + exercise (GFD + E); personalised gluten-free nutrition plan (GFD); celiac controls (NO-GFD); and non-celiac controls (CONTROL). The participants responded to the Menopause Rating Scale and the Profile of Mood States (POMS) questionnaires. Bone quality was measured with ultrasound and IgA with a blood test. After 12 weeks of intervention, the GFD + E group showed significant improvement in urogenital symptoms and scored higher on the ‘vigour’ subscale of the POMS. Negative associations were found between the total score on the Menopause Rating Scale and the ‘vigour’ subscale of the POMS questionnaire. Only those women who underwent a personalised GFD nutritional intervention combined with resistance exercise demonstrated significant changes after the intervention. © 2022 by the authors.

Psychological, Physiological, and Physical Effects of Resistance Training and Personalized Diet in Celiac Women

2022 , Martínez-Rodríguez, A. , Loaiza Martinez, Daniela , Sánchez-Sánchez, J. , Rubio-Arias, J.Á. , Alacid, F. , Prats-Moya, S. , Martínez-Olcina, M. , Yáñez-Sepúlveda, R. , Asencio-Mas, N. , Marcos-Pardo, P.J.

Background: Gluten intolerance is a systemic process of autoimmune nature; it develops in genetically predisposed subjects with gluten ingestion. The only treatment for celiac disease (CD) is a lifelong strict gluten-free diet (GFD). This study was designed to evaluate adherence to a GFD, risk of an eating disorder, and nutritional status in adult CD patients undergoing different interventions. Methods: A total of 28 Spanish women, aged 40 years or more, took part in a randomized controlled trial. Each group received a different intervention: group 1, gluten-free nutrition plan + exercise (GFD + E); group 2, gluten-free nutrition plan (GFD); group 3, celiac controls (NO-GFD); and group 4, non-celiac controls (CONTROL). The training was prescribed by a sport scientist. It was based on resistance training with elastic bands; beforehand a warm-up was performed and the resistance was increased progressively. The variables studied were adherence to the GFD, risk of eating disorders, blood values, and body composition. Results: Celiac women with personalized nutritional planning presented greater adherence to a gluten-free diet (p < 0.001). Regarding leukocytes, significant differences were observed between the GFD and control groups (p = 0.004). Perimeters and folds did not decrease significantly. Conclusion: Women with celiac disease who follow an adapted and personalized diet have a better adherence to a GFD compared to those who follow a non-professional diet, and therefore have a better immune system status (blood leukocytes).
