Cariogenic Risk in the Presence of Foods with Varied Glycemic Index in Dentistry Students. Cross-Sectional Study
(Fundacion Universitaria Maria Cano, 0025) Lisse Angarita Davila; Josefa Escobar Zoñez; Kaslyn Morales Cerda; Hector Fuentes Barria; Maria Eugenia Carrasco; Raul Aguilera
Introduction. Dentistry, a profession with high levels of stress, is associated with a decrease in quality of life and possible risks to oral health. Objective. Identify the cariogenic risk from foods consumed by dentistry students in the Biobío region. Methodology. Cross-sectional descriptive study with 178 dental students from the Biobio region (Chile), whose analysis considers the self-assessment of academic stress with the Academic Stress Inventory, cariogenic risk through the Lipari and Andrade Cariogenic Food Consumption Survey, and the glycemic index evaluated by the International Glycemic Index Tables. The statistical analysis considers the Chi-square test, with the effect size determined by Cramer’s V. Results. The students were 22.2 ± 3.1 years old. The prevalence of overweight or obesity was 44.4% (n = 79), 52.8% (n = 94) were of normal weight, and 2.8% (n = 5) were underweight. Additionally, 59.6% (n = 106) reported low stress levels and 57.8% (n = 103) had medium cariogenic risk. The analysis of cariogenic risk revealed significant differences in the intake of 14 food groups, especially those high in sugars. In the overweight/obesity subgroup, significant differences were observed in the consumption of milk, cookies, soda crackers, candies, and sweet pastries. Conclusion. An association was found between foods rich in sugar, nutritional sta-tus, and cariogenic risk, while appetizing foods were related to academic stress. © 2025. María Cano University Foundation.
The young exoplanetary system TOI-4562: Confirming the presence of a third body in the system
(LETTER TO THE EDITOR, 0024-10-09) Fermiano, V; Saito, RK; Ivanov, VD; Caceres, C; Almeida, LA; Aires, J; Beamin, JC; Minniti, D; Ferreira, T; Andrade, L; Borges, BW; de Almeida, L; Jablonski, F; Schlindwein, W
Young planetary systems represent an opportunity to investigate the early stages of (exo)planetary formation because the gravitational interactions have not yet significantly changed the initial configuration of the system. Aims. TOI-4562 b is a highly eccentric temperate Jupiter analogue orbiting a young F7V-type star of < 700 Myr in age with an orbital period of Porb similar to 225 days and an eccentricity of e = 0.76, and is one of the largest known exoplanets to have formed in situ. Methods. We observed a new transit of TOI-4562 b using the 0.6-m Zeiss telescope at the Pico dos Dias Observatory (OPD/LNA) in Minas Gerais, Brazil, and combine our data with Transiting Exoplanet Survey Satellite (TESS) and archive data, with the aim being to improve the ephemerides of this interesting system. Results. The O - C diagram for the new ephemeris is consistent with the presence of a giant planet in an outer orbit around TOI-4562. TOI-4562 c is a planet with a mass of M = 5.77 MJup, an orbital period of Porb = 3990 days, and a semi-major axis of a = 5.219 AU. Conclusions. We report the discovery of TOI-4562 c, the exoplanet with the longest orbital period discovered to date via the transit timing variation (TTV) method. The TOI-4562 system is in the process of violent evolution with intense dynamical changes - judging by its young age and high eccentricity - and is therefore a prime target for studies of formation and evolution of planetary systems.
Model Sets with Euclidean internal Space
(Cambridge University Press, 0022-11-07) Allendes Cerda, Mauricio; Coronel, Daniel
We give a characterization of inter-model sets with Euclidean internal space. This characterization is similar to previous results for general inter-model sets obtained independently by Baake, Lenz and Moody, and Aujogue. The new ingredients are two additional conditions. The first condition is on the rank of the abelian group generated by the set of internal differences. The second condition is on a flow on a torus defined via the address map introduced by Lagarias. This flow plays the role of the maximal equicontinuous factor in the previous characterizations. © The Author(s), 2023. Published by Cambridge University Press.
Statistical Analysis to Quantify the Impact of Map Type on Estimating Peak Discharge in Non-Instrumented Basins
(Universidad Tecnologica de Bolivar, 0023-08-11) Sierra-Sánchez, Alexandra; Gatica, Gustavo; Paternina-Verona, Duban A; Ramos, Helena M.
The calculation of peak discharge in non-instrumented basins requires including morphometric parameters, which in turn depend on the map type used. This study analyses the impact of and variation in peak discharges of the Caño Ricaurte basin, Colombia, based on three types of maps at different resolution scales. The reference map used was the map made for the detailed designs of the channel analysed, which was extracted from the Master Plan of the City. Additionally, maps from a 90 × 90 m digital elevation model and contour lines extracted from Google Earth were used. The time of concentration was determined by different equations (Kirpich, Témez, Bureau, and TR-55) using the mapping methods described above, and the peak discharge was determined using rainfall-runoff models. © 2023 by the authors.
Isokinetic trunk training on pain, disability, and strength in non-specific low back pain patients: A systematic review and meta-analysis
(IOS Press BV, 2023-11) Reyes-Ferrada, W.; Chirosa-Rios, L.; Martinez-Garcia, D.; Rodríguez-Perea, A.; Jerez-Mayorga, D.
BACKGROUND: Low back pain is one of the leading causes of disability globally, with a high economic and social burden. A decrease or imbalance in trunk strength has been associated with the occurrence of low back pain and its severity. Trunk strength training is helpful in the treatment of Non-specific low back pain (NSLBP) patients. However, we do not know the effects of trunk isokinetic training (IKT) on pain intensity, disability, and trunk strength. OBJECTIVE: This systematic review aimed to determine the effects of trunk IKT in NSLBP patients on pain intensity, disability, and trunk flexor and extensor isokinetic strength. METHODS: We searched PubMed, Web of Science, Scopus, CENTRAL, and PEDro, from January 2001 until March 2021 and updated to November 2022. Randomized controlled trials (RCTs) that investigated the effect of IKT in adult participants with NSLBP on pain intensity, disability, or isokinetic trunk strength were included. Mean difference (MD) and 95% confidence intervals (95% CI) were calculated for pain. Bias was assessed using the Cochrane risk of bias (RoB) tool and evidence certainty via Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Among 1750 retrieved articles, eight were included in this review. Meta-analysis comparing IKT (trunk isokinetic training, n= 134) with control groups (conventional exercises, n= 133) revealed that IKT decreases pain intensity (MD -1.50 (95% CI: -2.60; -0.39)) immediately post-intervention, and one month (MD -1.97 (95% CI: -2.92; -1.03)) and at six months follow-up (MD -2.48 (95% CI: -2.77; -2.19)), although with a very low to low quality according to the GRADE rating. Besides, IKT decreases disability and increases isokinetic trunk strength, but with scant evidence. CONCLUSIONS: Trunk IKT could be a novel clinical tool for pain management in patients with NSLBP, although evidence is scarce. In addition, few RCTs exist for IKT on disability or trunk isokinetic strength in patients with NSLBP. Therefore, further research on this topic is needed. © 2023 - IOS Press. All rights reserved.
