Anatomical Variants of the Origin of the Coronary Arteries: A Systematic Review and Meta-Analysis of Prevalence.

PURPOSE: The most common anomaly is an anomalous left coronary artery originating from the pulmonary artery. These variants can be different and depend on the location as well as how they present themselves in their anatomical distribution and their symptomatological relationship. For these reasons, this review aims to identify the variants of the coronary artery and how they are associated with different clinical conditions. METHODS: The databases Medline, Scopus, Web of Science, Google Scholar, CINAHL, and LILACS were researched until January 2024. Two authors independently performed the search, study selection, and data extraction. Methodological quality was evaluated using an assurance tool for anatomical studies (AQUA). Pooled prevalence was estimated using a random effects model. RESULTS: A total of 39 studies met the established selection criteria. In this study, 21 articles with a total of 578,868 subjects were included in the meta-analysis. The coronary artery origin variant was 1% (CI = 0.8-1.2%). For this third sample, the funnel plot graph showed an important asymmetry, with a p-value of 0.162, which is directly associated with this asymmetry. CONCLUSIONS: It is recommended that patients whose diagnosis was made incidentally and in the absence of symptoms undergo periodic controls to prevent future complications, including death. Finally, we believe that further studies could improve the anatomical, embryological, and physiological understanding of this variant in the heart.

Anatomical Variants of the Renal Veins and Their Relationship with Morphofunctional Alterations of the Kidney: A Systematic Review and Meta-Analysis of Prevalence.

Background: Variations in renal veins are quite common, and most people do not experience issues due to them. However, these variations are important for healthcare professionals, especially in surgical procedures and imaging studies, as precise knowledge of vascular anatomy is essential to avoid complications during medical interventions. The purpose of this study was to expose the frequency of anatomical variations in the renal vein (RV) and detail their relationship with the retroperitoneal and renal regions. Methods: A systematic search was conducted in the Medline, Scopus, Web of Science, Google Scholar, CINAHL, and LILACS databases from their inception until January 2024. Two authors independently carried out the search, study selection, and data extraction and assessed methodological quality using a quality assurance tool for anatomical studies (AQUA). Ultimately, consolidated prevalence was estimated using a random effects model. Results: In total, 91 studies meeting the eligibility criteria were identified. This study included 91 investigations with a total of 46,664 subjects; the meta-analysis encompassed 64 studies. The overall prevalence of multiple renal veins was 5%, with a confidence interval (CI) of 4% to 5%. The prevalence of the renal vein trajectory was 5%, with a CI of 4% to 5%. The prevalence of renal vein branching was 3%, with a CI of 0% to 6%. Lastly, the prevalence of unusual renal vein origin was 2%, with a CI of 1% to 4%. Conclusions: The analysis of these variants is crucial for both surgical clinical management and the treatment of patients with renal transplant and hemodialysis.

Effectiveness of supervised physiotherapy versus a home exercise program in patients with distal radius fracture: a randomized controlled trial with a 2-year follow-up.

OBJECTIVE: To determine in the long term whether supervised physiotherapy is more effective than a home exercise program for functional improvement and pain relief in patients with distal radius fracture (DRF). DESIGN: Randomized controlled trial. SETTING: Rehabilitation hospital. PARTICIPANTS: A total of 74 patients older than 60 years with extra-articular DRF were randomly allocated into two groups. INTERVENTIONS: The experimental group received 6 weeks of supervised physiotherapy (n = 37) and the control group received 6 weeks of home exercise program (n = 37). MAIN OUTCOME MEASURES: The primary outcome was wrist/hand function assessed using the Patient-Rated Wrist Evaluation (PRWE) questionnaire; secondary outcomes were the pain visual analogue scale (VAS), grip strength and wrist flexion-extension active range of motion. RESULTS: All patients completed the trial. For the primary outcome, at 6-weeks and 1-year follow-up, the PRWE questionnaire showed a mean difference between groups of 18.6 (95% CI 12.8 to 24.3) and 18.5 points (95% CI 12.7 to 24.2) respectively, these differences are clinically important. Conversely, at 2-year follow-up this effect decreases to 3.3 points (95% CI -2.4 to 9.0). For secondary outcomes, at 6-weeks and 1-year follow-up, in all measurements the effect size range from medium to large. Conversely, at 2-year follow-up only grip strength showed large effect size in favor of supervised physiotherapy, the rest of outcomes did not show difference between groups. CONCLUSION: At the 6-week and 1-year follow-up, supervised physiotherapy was more effective for functional improvement and pain relief compared with a home exercise program in patients older than 60 years with extra-articular DRF. However, this effect decreases over time, at the 2-year follow-up, only grip strength showed a difference in favor of supervised physiotherapy.

Association between the Anatomical Location of Glioblastoma and Its Evaluation with Clinical Considerations: A Systematic Review and Meta-Analysis.

Background: Glioblastoma is a primary malignant brain tumor; it is aggressive with a high degree of malignancy and unfavorable prognosis and is the most common type of malignant brain tumor. Glioblastomas can be located in the brain, cerebellum, brainstem, and spinal cord, originating from glial cells, particularly astrocytes. Methods: The databases MEDLINE, Scopus, Web of Science, Google Scholar, and CINAHL were researched up to January 2024. Two authors independently performed the search, study selection, and data extraction. Methodological quality was evaluated with an assurance tool for anatomical studies (AQUA). The statistical mean, standard deviation, and difference of means calculated with the Student's t-test for presence between hemispheres and presence in the frontal and temporal lobes were analyzed. Results: A total of 123 studies met the established selection criteria, with a total of 6224 patients. In relation to the mean, GBM between hemispheres had a mean of 33.36 (SD 58.00) in the right hemisphere and a mean of 34.70 (SD 65.07) in the left hemisphere, due to the difference in averages between hemispheres. There were no statistically significant differences, p = 0.35. For the comparison between the presence of GBM in the frontal lobe and the temporal lobe, there was a mean in the frontal lobe of 23.23 (SD 40.03), while in the temporal lobe, the mean was 22.05 (SD 43.50), and for the difference in means between the frontal lobe and the temporal lobe, there was no statistically significant difference for the presence of GBM, p = 0.178. Conclusions: We believe that before a treatment, it will always be correct to know where the GBM is located and how it behaves clinically, in order to generate correct conservative or surgical treatment guidelines for each patient. We believe that more detailed studies are also needed to show why GBM is associated more with some regions than others, despite the brain structure being homologous to other regions in which GMB occurs less frequently, which is why knowing its predominant presence in brain regions is very important.

Food Insecurity and Sleep-Related Problems in Adolescents: Findings from the EHDLA Study.

PURPOSE: The current research aimed to investigate the connection between food insecurity and sleep issues among Spanish adolescents aged from 12 to 17 years from the Valle de Ricote (Region of Murcia, Spain). METHODS: Data from the Eating Healthy and Daily Life Activities Study, which included a sample of 836 adolescents (55.3% girls), were analyzed. Food insecurity was evaluated using the Child Food Security Survey Module in Spanish (CFSSM-S), while sleep-related problems were evaluated using the Bedtime problems, Excessive daytime sleepiness, Awakenings during the night, Regularity and duration of sleep, and Sleep-disordered breathing (BEARS) sleep screening tool. Generalized linear models were employed to explore the association between food insecurity and sleep-related issues. RESULTS: Compared with their counterparts with food security, adolescents with food insecurity had greater probabilities of bedtime problems (24.1%, 95% confidence interval (CI) 16.9% to 33.0%, p = 0.003), excessive daytime sleepiness (36.4%, 95% CI 27.5% to 46.3%, p < 0.001), awakenings during the night (16.7%, 95% CI 10.8% to 25.1%, p = 0.004), and any sleep-related problems (68.1%, 95% CI 57.5% to 77.1%, p < 0.001). CONCLUSIONS: This study suggests that food insecurity is related to greater sleep-related problems among adolescents. Implementing strategies to mitigate food insecurity may contribute to improved sleep health among adolescents, highlighting the importance of integrated public health interventions.

Prevalence of obesity and associated sociodemographic and lifestyle factors in Ecuadorian children and adolescents.

BACKGROUND: Given the increasing prevalence of obesity in young people in Ecuador, there is a need to understand the factors associated with this condition. The aim of this study was to assess the prevalence of obesity in Ecuadorian children and adolescents aged 5-17 years and identify its associated sociodemographic and lifestyle factors. METHODS: This cross-sectional study was conducted using data from the Encuesta Nacional de Salud y Nutrición (ENSANUT-2018). The final sample consisted of 11,980 participants who provided full information on the variables of interest. RESULTS: The prevalence of obesity was 12.7%. A lower odd of having obesity was observed for adolescents; for those with a breadwinner with an educational level in middle/high school or higher; for each additional day with 60 or more minutes of daily moderate-to-vigorous physical activity; and for those with greater daily vegetable consumption (one, two, or three or more servings). Conversely, there were greater odds of obesity in participants from families with medium, poor, and very poor wealth and those from the coast and insular region. CONCLUSIONS: The high prevalence of obesity in Ecuadorian children and adolescents is a public health concern. Sociodemographic and lifestyle behavior differences in young people with obesity should be considered when developing specific interventions. IMPACT: As the prevalence of obesity among children and adolescents increases in Latin America, with a particular focus on Ecuador, it becomes crucial to delve into the factors linked to this condition and identify the most successful strategies for its mitigation. The elevated prevalence of obesity among young individuals in Ecuador raises significant public health concerns. To develop targeted interventions, it is crucial to account for sociodemographic variables and lifestyle behaviors that contribute to obesity in this population.

Association of IGF-1 and IGF-2 genotypes with respiratory muscle strength in individuals with COPD: A cross-sectional study / Asociación de los genotipos de IGF-1 e IGF-2 con la fuerza muscular respiratoria en individuos con EPOC: estudio transversal

Introduction Chronic obstructive pulmonary disease is a systemic disease characterized not only by respiratory symptoms but also by physical deconditioning and muscle weakness. One prominent manifestation of this disease is the decline in respiratory muscle strength. Previous studies have linked the genotypes of insulin-like growth factor 1 and 2 (IGF-1 and IGF-2) to muscle weakness in other populations without this disease. However, there is a notable knowledge gap regarding the biological mechanisms underlying respiratory muscle weakness, particularly the role of IGF-1 and IGF-2 genotypes in this pulmonary disease. Therefore, this study aimed to investigate, for the first time, the association between IGF-1 and IGF-2 genotypes with respiratory muscle strength in individuals with chronic obstructive pulmonary disease. In addition, we analyzed the relationship between oxidative stress, chronic inflammation, and vitamin D with respiratory muscle strength. Methods A cross sectional study with 61 individuals with chronic obstructive pulmonary disease. Polymerase chain reaction of gene polymorphisms IGF-1 (rs35767) and IGF-2 (rs3213221) was analyzed. Other variables, related to oxidative stress, inflammation and Vitamin D were dosed from peripheral blood. Maximal inspiratory and expiratory pressure were measured. Results The genetic polymorphisms were associated with respiratory muscle strength ( 3.0 and 3.5; = 0.57). Specific genotypes of IGF-1 and IGF-2 presented lower maximal inspiratory and expiratory pressure (<0.05 for all). Oxidative stress, inflammatory biomarkers, and vitamin D were not associated with respiratory muscle strength. Conclusion The polymorphisms of IGF-1 and IGF-2 displayed stronger correlations with respiratory muscle strength compared to blood biomarkers in patients with chronic obstructive pulmonary disease. Specific genotypes of IGF-1 and IGF-2 were associated with reduced respiratory muscle strength in this population.

Introducción La enfermedad pulmonar obstructiva crónica es una enfermedad sistémica caracterizada no solo por síntomas respiratorios, sino también por el deterioro físico y la debilidad muscular. Una manifestación destacada de esta enfermedad es el declive en la fuerza de los músculos respiratorios. Estudios previos han vinculado los genotipos de factor de crecimiento insulínico 1 y 2 (IGF-1 e IGF-2) con la debilidad muscular en poblaciones sin esta enfermedad. Sin embargo, existe un vacío de conocimiento con respecto a los mecanismos biológicos subyacentes a la debilidad de los músculos respiratorios, en particular el papel de los genotipos IGF-1 e IGF-2 en esta enfermedad pulmonar. Por lo tanto, este estudio tuvo como objetivo investigar, por primera vez, la asociación de los genotipos IGF-1 e IGF-2 con la fuerza de los músculos respiratorios en individuos con enfermedad pulmonar obstructiva crónica. Además, analizamos la relación entre el estrés oxidativo, la inflamación crónica y la vitamina D con la fuerza de los músculos respiratorios. Métodos Un estudio transversal con 61 individuos con enfermedad pulmonar obstructiva crónica. Se analizó la reacción en cadena de la polimerasa de los polimorfismos genéticos IGF-1 (rs35767) e IGF-2 (rs3213221). Otras variables relacionadas con el estrés oxidativo, la inflamación y la vitamina D se dosificaron a partir de muestras de sangre periférica. Se midieron las presiones inspiratorias y espiratorias máximas. Resultados Los polimorfismos genéticos están asociados con la fuerza de los músculos respiratorios (F: 3.0 y 3.5; R2= 0.57). Genotipos específicos de IGF-1 e IGF-2 presentaron bajos valores en las presiones inspiratorias y espiratorias (p<0.05 en todos los casos). El estrés oxidativo, los biomarcadores inflamatorios y la vitamina D no se asociaron con la fuerza de los músculos respiratorios. Conclusión Los polimorfismos de IGF-1 e IGF-2 mostraron correlaciones más sólidas con la fuerza de los músculos respiratorios en pacientes con enfermedad pulmonar obstructiva crónica en comparación con los biomarcadores sanguíneos. Genotipos específicos de IGF-1 e IGF-2 se asociaron con una disminución de la fuerza de los músculos respiratorios en esta población

Family Meals and Social Eating Behavior and Their Association with Disordered Eating among Spanish Adolescents: The EHDLA Study.

PURPOSE: The aim of this study was to examine the association of family meals and social eating behavior with disordered eating behavior in Spanish adolescents. METHODS: This was a cross-sectional study that included 706 adolescents (43.9% boys) from the Eating Habits and Daily Life Activities (EHDLA) study (aged 12 to 17) from Valle de Ricote, Region of Murcia, Spain. The frequency of family meals was assessed by asking participants to report how often their family, or most household members, had shared meals in the past week. Social eating behavior was evaluated using three statements: "I enjoy sitting down with family or friends for a meal", "Having at least one meal a day with others (family or friends) is important to me", and "I usually have dinner with others". To evaluate disordered eating, two psychologists administered the Sick, Control, One, Fat and Food (SCOFF) questionnaire. RESULTS: After adjusting for several covariates, for each additional family meal, the likelihood of having disordered eating behavior was lower (odds ratio (OR) = 0.96; 95% confidence interval (CI) 0.93 to 0.9997, p = 0.049). On the other hand, a lower likelihood of having disordered eating behavior was observed for each additional point in the social eating behavior scale (OR = 0.85; 95% CI 0.77 to 0.93, p = 0.001). The likelihood of having disordered eating behavior was 0.7% lower for each additional family meal (95% CI 0.01% to 1.4%, p = 0.046). Furthermore, for each additional point in the social eating behavior scale, a lower probability of having disordered eating behavior was observed (3.2%; 95% CI 1.4% to 5.0%, p < 0.001). CONCLUSIONS: While disordered eating behavior is complex and can be shaped by various factors, both family meals and social eating behavior emerge as significant factors inversely associated with this condition among adolescents. Promoting regular engagement in family meals and fostering positive social eating experiences could serve as effective strategies in public health initiatives aimed at mitigating the incidence of disordered eating behavior among the young population.

Higher Numbers of Family Meals and Social Eating Behavior Are Associated with Greater Self-Esteem among Adolescents: The EHDLA.

BACKGROUND: the aim of this study was to assess the associations of family meals and social eating behavior with self-esteem levels among Spanish adolescents. METHODS: This was a secondary cross-sectional study including 706 participants (aged 12 to 17 years; 56.1% girls) from the Eating Habits and Daily Life Activities (EHDLA) study. The evaluation of the frequency of family meals involved participants providing information in physical education classes on how frequently they, along with other members of their household, had shared meals in the previous week. Social eating behavior was assessed by three different statements: "I usually have dinner with others", "Having at least one meal a day with others (family or friends) is important to me", and "I enjoy sitting down with family or friends for a meal". To assess overall self-esteem, the Rosenberg Self-Esteem Scale was used. RESULTS: In the adjusted models, a positive association was observed between the frequency of family meals and the self-esteem score (unstandardized beta coefficient [B] = 0.06, 95% confidence interval [CI] 0.003 to 0.12, p-adjusted = 0.040). Furthermore, the same positive association was also identified between social eating behavior and the self-esteem score (B = 0.23; 95% CI 0.07 to 0.40, p-adjusted = 0.005). CONCLUSIONS: Although self-esteem is complex and can be influenced by numerous factors, both family meals and social eating behavior may exert a relevant role in adolescents. Encouraging consistent participation in family meals and promoting positive eating practices could be valuable approaches in public health actions targeting the enhancement of self-esteem levels in adolescents.

The Association between Anatomical Variants of Musculoskeletal Structures and Nerve Compressions of the Lower Limb: A Systematic Review and Meta-Analysis.

Objective: The aim of this study was to describe the main anatomical variants and morphofunctional alterations in the lower limb that compress surrounding nervous structures in the gluteal region, thigh region, and leg and foot region. Methods: We searched the Medline, Scopus, Web of Science, Google Scholar, CINAHL, and LILACS databases from their inception up to October 2023. An assurance tool for anatomical studies (AQUA) was used to evaluate methodological quality, and the Joanna Briggs Institute assessment tool for case reports was also used. Forest plots were generated to assess the prevalence of variants of the gluteal region, thigh, and leg. Results: According to the forest plot of the gluteal region, the prevalence was 0.18 (0.14-0.23), with a heterogeneity of 93.52%. For the thigh region, the forest plot presented a prevalence of 0.10 (0.03-0.17) and a heterogeneity of 91.18%. The forest plot of the leg region was based on seven studies, which presented a prevalence of 0.01 (0.01-0.01) and a heterogeneity of 96.18%. Conclusions: This review and meta-analysis showed that, in studies that analyzed nerve compressions, the prevalence was low in the thigh and leg regions, while in the gluteal region, it was slightly higher. This is mainly due to the PM region and its different variants. We believe that it is important to analyze all the variant regions defined in this study and that surgeons treating the lower limb should be attentive to these possible scenarios so that they can anticipate possible surgical situations and thus avoid surgical complications.

Lifestyle behavior of physiotherapy students from Ecuador upon admission to higher education: a cross-sectional study.

Introduction: Admission to university has been identified as a period involving the adoption of unhealthy lifestyle behaviors. However, few studies have addressed the extent of this experience among Latin American university students. The aim of this study was twofold: first, to describe anthropometric variables, body composition, physical activity, sedentary behavior, sleep duration and quality, diet, and alcohol consumption in first-year students entering physiotherapy school at the Universidad de las Americas in Quito, Ecuador; second, to test differences in these variables between sexes. Methods: A total of 116 students were recruited. Sociodemographic variables, anthropometric indices, body composition, physical activity, sedentary behavior, sleep quality and duration, adherence to 24-hour movement guidelines, physical fitness (i.e., handgrip strength), diet, alcohol consumption, and smoking habits were evaluated. Results: A total of 50 male (43.1%) and 66 female (56.9%) students were assessed. Overall, the adherence to the 24-hour movement guidelines of the students upon admission to university was 8.6%. Conversely, 86 students (74.1%) did not meet any of the recommendations. Upon admission to university, only 8.6% of the students (female 2.6%; male 6%) met the overall 24-hour movement guidelines. Additionally, 82 students (70.7%) needed changes in diet quality, 81 students (69.8%) had significant sleep disturbances, and 22 students (18.9%) had harmful alcohol consumption. A greater proportion of males met all three 24-h movement recommendations (p = 0.025) than females did. In addition, females reported a greater percentage of occasional smokers (p = 0.025) and a greater prevalence of obesity (p < 0.001), a lower level of physical activity (p < 0.001), and a greater percentage of sleep disturbance (p < 0.001). Conversely, males reported greater waist circumference (p = 0.005), weight (p < 0.001), handgrip strength (p < 0.001), and a greater percentage of harmful alcohol consumption (p < 0.001). Discussion: Our study showed that upon admission to university, overall adherence to the 24-hour movement guidelines is low among university students. Additionally, a high percentage of students reported unhealthy lifestyle behaviors, with differences according to sex. Our findings could lead to the use of specific sex-specific strategies for the prevention and promotion of movement and lifestyle behaviors during this critical period.

Arthroscopic Assistance in Surgical Management of Distal Radius Fractures: A Systematic Review and Meta-analysis.

Background Wrist arthroscopy has become a commonly used tool for the management of adults with distal radius fractures (DRFs), although its implementation requires technical competence. This systematic review and meta-analysis appraised the available evidence concerning the contribution of wrist arthroscopy to the functional and radiological outcomes of patients with DRFs operated with arthroscopic assistance. Methods Randomized control trials were identified through five principal electronic databases on May 31, 2022: Web of Science, Scopus, EBSCO, Embase, and PubMed. Two authors independently performed the search and data extraction and assessed risk of bias (RoB) using the Cochrane RoB tool. Results A total of 1,780 relevant abstracts and citations were extracted in the preliminary search, which yielded 6 trials that met the eligibility criteria, and 3 studies were included in the quantitative synthesis. The overall pooled mean difference (MD) estimate showed no significant difference in the Disabilities of the Arm, Shoulder, and Hand scores between surgical groups with and without arthroscopic assistance (MD = 0.77 points, 95% confidence interval = -6.58 to 5.03, p = 0.79), with substantial heterogeneity (I 2 = 85%). Conclusion There was low-quality evidence that wrist arthroscopy conveyed not clinically or statistically significant difference to functional outcomes of patients with DRFs. However, our findings are limited by the numbers of studies included and lack of long-term follow-up, although they do provide a good starting point for future quality research.

Effects of a Conventional Treatment Plus Scapular Exercises Program in Patients With Chronic Lateral Elbow Tendinopathy: A Pre-Post Single-Group Study.

BACKGROUND: Weakness of the shoulder girdle muscles has been reported in patients with chronic lateral elbow tendinopathy. The aim of this study was to assess the short- and long-term effects of a conventional treatment plus scapular exercises program in patients with chronic lateral elbow tendinopathy. METHODS: A single-group prestudy and poststudy were conducted. The primary outcome was the Patient-Rated Tennis Elbow Evaluation questionnaire score. Secondary outcomes were grip strength; Disabilities of the Arm, Shoulder, and Hand questionnaire score; Visual Analogue Scale score at rest and at grip, and presence of scapular dyskinesis. RESULTS: A total of 65 patients (72.3% females), with a mean age of 41.8 years, were analyzed. At the end of 6 weeks, the results showed clinically and statistically significant differences (P < .05). At 1-year follow-up, the differences were: Patient-Rated Tennis Elbow Evaluation -31 points (P < .001); grip strength +33.6% (P < .001); Disabilities of the Arm, Shoulder, and Hand -34.2 points (P < .001); Visual Analogue Scale at rest -2.5 cm (P < .001); and Visual Analogue Scale at grip -2.3 cm (P < .001). CONCLUSION: At the end of 6 weeks and at 1-year follow-up, conventional treatment plus scapular exercises program showed statistically and clinically significant differences in all functional outcomes assessed in patients with lateral elbow tendinopathy.

Intra-articular Pressure in the Distal Radioulnar Joint: A Biomechanical Study.

PURPOSE: The aim of the study was to use cadaveric models to assess the effect of loading the forearm muscles in different forearm rotations, with or without disruption to the stabilizing components, on the intra-articular pressure of the distal radioulnar joint (DRUJ). METHODS: Ten forearms with no severe osteoarthritis or injury to the DRUJ stabilizers were used. They were placed in a vertical support, and pressure sensors measured pressure within the DRUJ in 5 forearm rotations (neutral, pronation, supination, extension, and flexion) under the following 6 conditions: 1) no loading; 2) loading (at 1/5 of the load per cross-sectional area) with no disruption; 3) loading with disruption of the triangular fibrocartilage complex (TFCC); 4) loading with disruption of the TFCC and ulnar ligaments (ULs); 5) loading with disruption of the TFCC, ULs and interosseous membrane (IM); and 6) loading with disruption of the TFCC, ULs, IM, and pronator quadratus (PQ). RESULTS: Under the no disruption-no load, no disruption-loaded, and disrupted TFCC conditions, the highest intra-articular pressures were recorded in supination. Compared with the no-load condition, pressure was greater in the no disruption-loaded condition with a mean difference (MD) of 1.57 kg/cm2 in a neutral position. In flexion, pressure was greater with a disrupted TFCC (MD, 4.3 kg/cm2). In supination, pressure was only greater with a disrupted TFCC (MD, 3.3 kg/cm2), and pressure decreased in the other disruption conditions. The pressures recorded did not differ from the no disruption-no load condition in pronation or extension. CONCLUSIONS: Pressures within the DRUJ changed with forearm rotations. In the no disruption-no load, no disruption-loaded, and disrupted TFCC conditions, intra-articular pressure was highest in supination. In flexion and supination with load and disruption of stabilizers, intra-articular pressure only increased significantly in the disrupted TFCC condition compared with no load. CLINICAL RELEVANCE: Based on our findings, exercises in supination should be avoided during the first phase of rehabilitation of TFCC injuries given the increased pressure on the DRUJ.

Overall proportion of orthorexia nervosa symptoms: A systematic review and meta-analysis including 30 476 individuals from 18 countries.

Background: To date, no previous meta-analysis has determined the overall proportion of orthorexia nervosa symptoms on a global scale. The aim of the present study was 2-fold: first, to establish the overall proportion of orthorexia nervosa symptoms on a global scale, assessed with the ORTO-15 questionnaire; and second, to determine the role of sex, type of population, mean age, body mass index, and the temporal trend in relation to orthorexia nervosa symptoms. Methods: Four databases were searched (PubMed, Scopus, Web of Science, and Cochrane Database of Systematic Reviews) with date limits from January 2005 to June 2023. Studies assessing the proportion of orthorexia nervosa assessed using the ORTO-15 questionnaire with a cutoff of <35 or <40 points were included in this review. Results: The overall proportion of orthorexia nervosa symptoms (using the cutoff <35 points) was 27.5% (95% confidence interval (CI) = 23.5-31.6, I2 = 97.0%). In addition, no significant differences were observed between females (34.6%, 95% CI = 29.5-39.8, I2 = 96.1%) and males (32.1%, 95% CI = 26.5-38.1, I2 = 93.1%). According to the type of population, the highest overall proportion was found in people focused on sports performance or body composition (34.5%, 95% CI = 23.1-47.0, I2 = 98.0%). Notwithstanding, caution should be exercised in interpreting this result, as reverse causality could be a potential pitfall in this relationship. Conclusions: We found that approximately three out of 10 study participants showed orthorexia nervosa symptoms according to the ORTO-15 tool. This overall proportion was higher in those participants who were athletes or fitness practitioners. Over the years, the proportion of orthorexia nervosa symptoms seems to be increasing. These high percentages and their increase are worrisome from a public health perspective and highlight the need to develop psychometric instruments to aid in clinical diagnosis and treatment efficacy.

Periodized Aerobic Training between Thresholds Improves Submaximal Cardiorespiratory Parameters in Octogenarians.

BACKGROUND AND AIMS: The worldwide aging population is expanding, with more individuals living into their 80s. Physiological functions decline gradually with age, compounded by sedentary lifestyles. Incorporating physical activity into daily routine is crucial for maintaining independence. This study aimed to assess a periodized high-intensity aerobic training program (PEZO-BT) in octogenarians, focusing on submaximal ergospirometry effects. METHODS: A total of 48 non-frail octogenarian subjects (12 females, 36 males) were randomized into control and intervention groups. All subjects underwent submaximal cardiopulmonary exercise testing with gas analysis at baseline, stopping after the respiratory compensation point (RCP). Our intervention group completed a 14-week PEZO-BT aerobic training program. The outcomes were oxygen consumption at first ventilatory threshold (VO2AT), ventilatory efficiency slope (VE/VCO2), oxygen uptake efficiency slope (OUES), cardiorespiratory optimal point (COP), oxygen pulse change (ΔVO2/HR) from anaerobic threshold (AT) to respiratory compensation point (RCP), and power output at anaerobic threshold (POAT). RESULTS: Mixed ANOVA examined time and treatment effects. If significance emerged, post hoc t-tests were used to compare significances between groups. The homogeneity of variance was assessed using Levene's test. Chi-square tests compared ergospirometry criteria and ventilatory performance within groups. The mean differences at post intervention were significant in VO2AT (p < 0.001), VE/VCO2 (p < 0.001), ΔVO2/HR (p < 0.05), and POAT (p < 0.001), while OUES and COP were not significant (p > 0.05). However, clinical effects were observed in the entire intervention group. CONCLUSIONS: Training improved exercise capacity and workload. Overall, this periodic aerobic and high-intensity interval training (HIIT) program yielded significant improvements in cardiorespiratory fitness (CRF) in previously untrained octogenarians with and without comorbidities. The findings suggest implications for promoting long-term healthy aging.

Specific versus general exercise programme in adults with subacromial impingement syndrome: a randomised controlled trial.

Objectives: Current evidence on the clinical effectiveness about the different types of exercises in the subacromial impingement syndrome (SIS) remains controversial. This study aims to compare the short-term (at 5 weeks) effects of a specific exercise programme with a general exercise programme on shoulder function in adults with SIS. Methods: In total, 52 adults with SIS were randomly allocated to 5 weeks to perform specific exercises (experimental group, n=26) or general exercises (control group, n=26). The primary outcome was change in shoulder function, it was assessed using the Shoulder Pain and Disability Index (SPADI) from baseline to 5 weeks. Secondary end points included changes in upper limb function (Disabilities of the Arm, Shoulder, and Hand (DASH) Questionnaire), pain intensity (Visual Analog Scale (VAS)) and kinesiophobia (Tampa Scale of Kinesiophobia (TSK)). Results: All participants completed the trial. The between-group differences at 5 weeks were: SPADI, 13.5 points (95% CI: 4.3 to 15.6; ƞ2=0.22; p=0.001); DASH, 10.1 points (95% CI: 5.6 to 15.2; ƞ2=0.27; p<0.001); VAS at rest, 0.2 cm (95% CI: 0.1 to 0.3; ƞ2=0.07; p=0.553); VAS on movement, 1.7 cm (95% CI: 0.9 to 2.2; ƞ2=0.24; p<0.001); and TSK, 16.3 points (95% CI: 13.2 to 15.3; ƞ2=0.33; p<0.001). All differences favoured the experimental group and effect sizes were medium to large for most outcomes. Mediation analyses showed that the effect of the specific exercises on shoulder function was mediated by kinesiophobia (ß=2.800; 95% CI: 1.063 to 4.907) and pain on movement (ß= -0.690; 95% CI: -1.176 to -0.271). Conclusion: In adults with SIS, specific exercises may have a larger effect than general exercises. However, most differences did not reach the minimum threshold to be considered clinically important and the evidence to support exercise as standard treatment warrant further study.

Correlación entre los Estilos de Aprendizaje Según el Modelo de Felder-Silverman y el Rendimiento Académico de la Asignatura de Morfología y Función en Estudiantes Universitarios / Correlation Between Learning Styles According to the Felder-Silverman Model and the Academic Performance of the Morphology and Function Subject in University Students

El objetivo del estudio fue determinar la relación existente entre la tendencia predominante del estilo de aprendizaje, según el modelo de Felder-Silverman, evaluando el rendimiento académico parcial y final de los estudiantes que cursan la asignatura Morfología y Función I. Se realizó un estudio transversal en 231 estudiantes universitarios que ingresaron a las Facultades de Salud y Educación en el primer semestre del año 2019. Para poder evaluar el rendimiento, a los estudiantes se les aplicó el cuestionario de Índice de Estilos de Aprendizaje y se correlacionó con la nota de la prueba teórica 1, la evaluación práctica 1 y el promedio final de la asignatura. Los resultados muestran que el 53,4 % del total de estudiantes evaluados son visuales, para estos estudiantes el coeficiente de correlación de Spearman fue de -0,378 para prueba teórica (p<0,001), -0.467 para evaluación práctica (p<0,001) y -0.500 para el promedio final (p<0,001). Los estudiantes visuales tienen promedio de notas más altos en la prueba teórica y el promedio final comparado con los activos (p<0,05). Se concluyó que la tendencia predominante es el visual, para estos estudiantes existe una correlación inversa y estadísticamente significativa con el rendimiento académico. Además, presentan un promedio de notas significativamente más alto que las otras tendencias.

SUMMARY: The objective if this study was to determine the relation that exists between the predominant tendency of the learning style, according to the Felder-Silverman model, and partial and final academic performance of the students attending the subject Morphology and Function I. A transversal study was carried out among 231 college students who joined the Faculties of Health and Education during the first term of 2019. They received the Index of Learning Styles Questionnaire and it was correlated with the mark of the theoretical test n°1, the practical evaluation n° 1 and the final average of the course. Results showed that 53.4 % of the total numbers of students assessed are visual, for these pupils the Spearman correlation coefficient was -0.378 for the theoretical test (p<0.001),-0.467 for the practical evaluation (p<0.001) and -0.500 for the final average (p<0.001). Visual students have higher average marks in the theoretical test and the final average contrasted with the active ones (p<0.05). We concluded that the predominant tendency is the visual style. For these students there is an inverted and statistically significant correlation with the academic performance. Besides, they show significantly higher average marks than the other tendencies.

Effectiveness of Glenohumeral Joint Mobilization on Range of Motion and Pain in Patients With Rotator Cuff Disorders: A Systematic Review and Meta-Analysis.

OBJECTIVE: The purpose of this study was to determine the effectiveness of glenohumeral joint mobilization (JM) on range of motion and pain intensity in patients with rotator cuff (RC) disorders. METHODS: An electronic search was performed in the MEDLINE, CENTRAL, Embase, PEDro, LILACS, CINAHL, SPORTDiscus, and Web of Science databases. The eligibility criteria for selecting studies included randomized clinical trials that investigated the effect of glenohumeral JM techniques with or without other therapeutic interventions on range of motion, pain intensity, and shoulder function in patients older than 18 years with RC disorders. Two authors independently performed the search, study selection, and data extraction, and assessed risk of bias. Grades of Recommendation Assessment, Development and Evaluation ratings were used to evaluate the quality of evidence in this study. RESULTS: Twenty-four trials met the eligibility criteria, and 15 studies were included in the quantitative synthesis. At 4 to 6 weeks, for glenohumeral JM with other manual therapy techniques vs other treatments, the mean difference (MD) for shoulder flexion was -3.42° (P = .006), abduction 1.54° (P = .76), external rotation 0.65° (P = .85), and Shoulder and Pain Disability Index score 5.19 points (P = .5), and standard MD for pain intensity was 0.16 (P = .5). At 4 to 5 weeks, for the addition of glenohumeral JM to an exercise program vs exercise program alone, the MD for the visual analog scale was 0.13 cm (P = .51) and the Shoulder and Pain Disability Index score was -4.04 points (P = .01). CONCLUSION: Compared with other treatments or an exercise program alone, the addition of glenohumeral JM with or without other manual therapy techniques does not provide significant clinical benefit with respect to shoulder function, range of motion, or pain intensity in patients with RC disorders. The quality of evidence was very low to high according to Grades of Recommendation Assessment, Development and Evaluation ratings.
