Can Suttonella ornithocola entail a potential hazard to songbirds? A systematic review
No full textPasseriformes populations have experienced a marked decline in number during the last decades. Several infectious agents have been described as key factors for this population’s decrease, as they can cause mortal diseases like the recently reported Suttonella ornithocola. S. ornithocola is a bacterium from the Cardiobacteriaceae family that has been linked to several outbreaks. This systematic review aims to collect all the scientific information available about S. ornithocola to better understand its epidemiology and pathogenesis and to assess the potential hazard that it can pose to garden songbirds. Although it has been considered a respiratory pathogen, S. ornithocola has been isolated from several organs, suggesting a systemic pathogenesis. However, it has also been described as a normal taxon from the microbiota of some bird species. Therefore, further studies in healthy birds are necessary to establish if S. ornithocola is a primary pathogen or an opportunistic bacterium in songbirds.Sin financiación2.0 Q3 JCR 20220.558 Q2 SJR 2023No data IDR 202
The effect of physical exercise on anticancer immunity
No full textRegular physical activity is associated with lower cancer incidence and mortality, as well as with a lower rate of tumour recurrence. The epidemiological evidence is supported by preclinical studies in animal models showing that regular exercise delays the progression of cancer, including highly aggressive malignancies. Although the mechanisms underlying the antitumorigenic effects of exercise remain to be defined, an improvement in cancer immunosurveillance is likely important, with different immune cell subtypes stimulated by exercise to infiltrate tumours. There is also evidence that immune cells from blood collected after an exercise bout could be used as adoptive cell therapy for cancer. In this Perspective, we address the importance of muscular activity for maintaining a healthy immune system and discuss the effects of a single bout of exercise (that is, 'acute' exercise) and those of 'regular' exercise (that is, repeated bouts) on anticancer immunity, including tumour infiltrates. We also address the postulated mechanisms and the clinical implications of this emerging area of research.
Epidemiological evidence indicates that physical exercise can lower cancer incidence and mortality. This Perspective discusses the importance of muscular activity for maintaining a healthy immune system and the potential mechanisms by which exercise affects anticancer immunity.Wereld Kanker Onderzoek Fonds (WKOF), as part of the World Cancer Research Fund International grant programme (IIG_FULL_2021_007)Spanish Ministry of Science and Innovation (Fondo de Investigaciones Sanitarias (FIS)) and Fondos FEDER (PI18/00139)Spanish Ministry of Science and Innovation (Fondo de Investigaciones Sanitarias (FIS)) and Fondos FEDER (PI20/00645)Instituto de Salud Carlos III (CP18/00034)Instituto de Salud Carlos III (CD21/00138)100.3 Q1 JCR 202216.009 Q1 SJR 2023No data IDR 2022UE
Microtensile Bond Strength and Failure Mode of Different Universal Adhesives on Human Dentin
No full textAim: The aim of this study was to compare the microtensile bond strength (µTBS) and failure mode of 4 different universal adhesive systems (UAs) on human dentin.
Materials and methods: The study sectioned the occlusal thirds of 32 human third molars and divided them into 4 groups based on the adhesive system used. Group A: Palfique Universal Bond, Group B: Single Bond Universal, Group C: All-Bond Universal, and Group D: One Coat 7 Universal. The specimens underwent a 10,000-cycle thermocycling ageing process prior to testing (n = 32). Afterwards, 8 beams were obtained per group and subjected to µTBS testing using a digital universal testing machine at a speed of 1 mm/min. The microtensile bond strength values were analysed in Megapascals (MPa), and the failure mode was evaluated using a stereomicroscope. Welch's parametric ANOVA with robust variance and the Games-Howell post hoc test were used for µTBS comparisons, and Fisher's exact test was used to determine the association between adhesive type and failure mode. The significance level was set at P < .05.
Results: Group D showed a significantly higher µTBS than groups A (P < .001) and B (P < .001), but no significant difference was observed with group C (P= .075). Furthermore, groups B and C showed significantly higher µTBS than group A (P< .001 and P < .001, respectively), but there was no significant difference between groups B and C (P = .132). Additionally, group A exhibited a significant association with an adhesive failure mode (P < .05), whereas groups B, C, and D were significantly associated with a mixed failure mode (P < .05).
Conclusion: The One Coat 7 Universal adhesive system showed higher microtensile bond strength values and higher chemical interaction with dentin compared to Palfique Universal Bond and Single Bond Universal. However, no significant differences were observed compared to All-Bond Universal.Sin financiación3.3 Q2 JCR 2022;0.803 Q1 SJR 2023No data IDR 202
Immediate implant placement influenced by musical flow: a prospective randomized controlled clinical trial
No full textBackground The purpose of this study was to test how musical flow using baroque (BM) and classical era music (CM)
as a non-pharmacological therapy can control anxiety and pain levels among patients undergoing IPI (Immediate
post-extraction implants).
Methods 78 patients who required an IPI were enrolled in this randomized clinical trial. Each patient was assigned
to one of the three experimental groups with a simple randomization: Group I (n
=
26) listened to BM; Group II
(n
=
27) listened to CM; and Group III (n
=
25) did not listen to music and was the control group (C). The physiological
dependent variables analyzed were systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and
oxygen saturation (SpO2). The psychological dependent variable analyzed was modified dental anxiety scale (MDAS)
and visual analogue scale (VAS), measured before and after surgery. In all cases, the level of statistical significance was
set at p < 0.01.
Results Statistically significant differences were found in the SBP decrease in the CM group (p
=
0.001, CI
=
1.9716–
6.5840) and the BM group (p
=
0.003, CI
=
1.4450–6.4396). Anxiety levels during the intervention decreased in both
groups that listened to music: BM group (p
=
0.002, CI
=
0.645–2.662) and CM group (p
=
0.000, CI
=
1.523–3.884).
Conclusions Patients undergoing IPI placement surgery can register lower levels of SBP when listening to BM and
CM than patients who were not exposed to the musical flow, improving their anxiety levels.Sin financiación2.9 Q2 JCR 20220.737 Q1 SJR 2023No data IDR 2023UE
How does the country of origin affect tourist expenditure? An extended quantile regression analysis
No full textNationality is considered a highly relevant determinant of tourism expenditure. In this paper, we use survey data to estimate the main determinants of daily tourism expenditure in 2019 for five nationalities of a major coastal destination, the Canary Islands. A total of 38 regressors, based on literature, are used with the help of quantile regression analysis to understand the behaviour patterns of different expenditure segments. To obtain segmented information on the determinants of expenditure, independent quantile regression models for each nationality are estimated and compared. Results show that there are similarities but also some remarkable differences between nationalities regarding income, age, travel group, educational level, or content of the package that can be used in destination management and marketing.Sin financiación1.6 Q3 JCR 20230.514 Q2 SJR 2023No data IDR 2023UE

Análisis de la condición física, composición corporal, y perfil bioquímico y hormonal en las fases lútea y folicular durante una temporada en jugadoras adolescentes de voleibol de alto nivel
No full textEl efecto que el deporte de alto rendimiento provoca en las mujeres adolescentes ha sido poco estudiado en la literatura científica. En este contexto, algunos aspectos tales como el perfil hormonal, la composición corporal, los parámetros bioquímicos y la condición física pueden ser determinantes a la hora de establecer un control y un seguimiento de las deportistas y de su ciclo menstrual. Por lo tanto, el principal objetivo de esta tesis doctoral fue analizar las diferencias en las variables antropométricas, la composición corporal, parámetros bioquímicos de la sangre, perfil hormonal y el rendimiento de jugadoras adolescentes de voleibol de alto nivel en la fase folicular y la fase lútea del ciclo menstrual en distintos periodos de la temporada y en su totalidad. Las participantes fueron jugadoras adolescentes de voleibol (n = 16, edad = 16,1 ± 2,81 años), pertenecientes a la Concentración Permanente de Voleibol en el Centro de Alto Entrenamiento y Promoción Deportiva de Soria (Caep Soria).

Kronos 23(1). mediciones en jugadoras adolescentes de voleibol de alto nivel en diferentes momentos de la temporada que se corresponden con las fases folicular y lútea, y el periodo preparatorio y los periodos competitivos. Se analizó el rendimiento físico, se valoró el perfil hormonal y se controlaron parámetros bioquímicos con extracción sanguínea en 6 momentos de la temporada. Estos test se hicieron coincidir con las fases folicular y lútea de las jugadoras de manera individualizada y a lo largo de cada uno de los mesociclos de la planificación (preparatorio, competitivo 1 y competitivo 2). Además, se analizó la composición corporal en estos tres momentos concretos de la temporada para valorar el perfil antropométrico y de composición corporal de las jugadoras. Los principales resultados de esta tesis doctoral mostraron cambios significativos en el rendimiento en algunas pruebas de condición física (p<0,05). Concretamente, en el salto con bloqueo, en el salto horizontal y en el lanzamiento de balón medicinal de 3 kg, en la fase lútea con respecto a la folicular durante el periodo preparatorio; y en el test de lanzamiento de balón medicinal de 3 kg, en la fase folicular con respecto a la fase lútea durante el periodo competitivo 2. En el resto de las variables antropométricas, de composición corporal, y perfil bioquímico y hormonal no se encuentran diferencias significativas (p>0,05) entre las fases folicular y lútea. Sí se encuentran diferencias significativas entre los distintos periodos de la temporada en algunas de las variables, pero no siguen un patrón común. La conclusión principal de esta Tesis Doctoral es que es necesario controlar el ciclo menstrual de las deportistas adolescentes y establecer una organización de los entrenamientos acorde a este.The effect of high-performance sports on adolescent women has been underexplored in scientific literature. In this context, aspects such as hormonal profile, body composition, biochemical parameters, and physical condition may play a crucial role in monitoring and controlling athletes and their menstrual cycles. Therefore, the main objective of this doctoral thesis was to analyze differences in anthropometric variables, body composition, blood biochemical parameters, hormonal profile, and performance of high- level adolescent volleyball players in the follicular and luteal phases of the menstrual cycle across different phases and throughout the season. The participants were adolescent volleyball players (n = 16, age = 16.1 ± 0.81 years) from the Permanent Concentration of Volleyball at the High Training and Sports Promotion Center in Soria (Caep Soria). A descriptive, comparative, and longitudinal study was conducted, including measurements in high-level adolescent volleyball players at various points in the season corresponding to the follicular and luteal phases, as well as the preparatory3 Márquez Calle, E. (2024). Análisis de la condición física, composición corporal, y perfil bioquímico y hormonal en las fases lútea y folicular durante una temporada en jugadoras adolescentes de voleibol de alto nivel. Kronos 23(1). and competitive periods. Physical performance was analyzed, hormonal profiles were assessed, and blood biochemical parameters were monitored through blood extraction at six points during the season, aligned with individualized follicular and luteal phases across each mesocycle of the plan (preparatory, competitive 1, and competitive 2). The main results of this doctoral thesis showed significant changes in performance in some fitness tests (p<0.05). Specifically, in block jump, horizontal jump, and 3kg medicine ball throw, there were differences between luteal and follicular phases during the preparatory period, and in the 3kg medicine ball throw test, there were differences between follicular and luteal phases during competitive period 2. No significant differences (p>0.05) were found in other anthropometric variables, body composition, and biochemical and hormonal profiles between follicular and luteal phases. Significant differences were found between different periods of the season in some variables, but they did not follow a common pattern. The main conclusion of this doctoral thesis is that it is necessary to monitor the menstrual cycle of adolescent athletes and tailor training organization accordingly.Sin FinanciaciónNo data JCR 2023; No data SJR 2023; 0,24 C3 IDR 2022UE
