RESUMEN

En la educación superior, pocos estudios relacionan factores contextuales en la clase, como el énfasis del profesor en la utilidad del contenido y las características motivacionales de los estudiantes. El objetivo fue probar un modelo multinivel sobre la relación entre el énfasis del docente en la utilidad del contenido durante la clase, la autonomía de los estudiantes y, a su vez, la motivación para aprender. Participaron 3033 estudiantes universitarios matriculados de 1º a 4º grado de Ciencias de la Actividad Física y del Deporte, de universidades de España (N = 602), Portugal (N = 469), México (N = 1177), Chile (N = 372), y Brasil (N = 413). Se realizó un modelo de ecuaciones estructurales multinivel, en el que los participantes respondieron preguntas sobre el énfasis del profesor en la utilidad del contenido de la clase, la autonomía y la motivación para aprender. Se hipotetizó que el énfasis del profesor en la utilidad del contenido predecía la autonomía del estudiante que, por su vez, predecía la motivación para aprender. Los resultados, a nivel grupal e individual, indican que el énfasis del docente en la utilidad del contenido predijo la autonomía del estudiante, y la autonomía predijo la motivación para aprender.(AU)

Teacher autonomy support is related to improved student learn-ing. In higher education, few studies relate classroom contextual factors, such as teacher emphasis on content usefulness, and students' motivational characteristics. The aim was to test a multilevel model about the relation between the extent of teachers’ emphasis on the usefulness of class con-tent with student autonomy, and, in turn, on motivation to learn. The par-ticipants were 3033 university students enrolled from 1st to 4th grade of Sciences of the Physical Activity and Sport, from universities in Spain (N = 602), Portugal (N = 469), Mexico (N = 1177), Chile (N = 372), and Brazil (N = 413). A multilevel structural equation model was performed, in which participants answered questions about the teacher's emphasis on the use-fulness of class content, basic psychological need for autonomy, and moti-vation to learn. At the group and individual levels, the hypothesis is that the teacher's emphasis on the usefulness of class content predict the stu-dent autonomy, in turn, student autonomy predicts student motivation to learn. Results found at the group level and at the individual level the strength of teacher emphasis on class content predicted student autonomy; student autonomy predicted student motivation to learn.(AU)

RESUMEN

Based on the research results and development trend of modern life sciences, our team first proposed in 2020 that Dao-di herbs had the characteristics of "excellent shape, high quality, and superior effect", which broadened the scope of traditional medicinal herb description. In recent years, with the gradual deepening of the research on the natural, material, and medicinal properties of Dao-di herbs in traditional Chinese medicine(TCM), the scientific connotation of "excellent shape, high quality, and superior effect" of Dao-di herbs has been enriched. "High quality" is mainly embodied in the fact that Dao-di herbs have a "unique chemotype", which can be used as the material basis of "superior effect" and can participate in regulating the formation of "excellent shape". Similar to the principle of "unity of body and spirit", in the process of long-term evolution, Dao-di herbs gradually form unique environmental adaptive characteristics, which is manifested as the "unity of shape and quality". The characteristics of "excellent shape, high quality, and superior effect" of Dao-di herbs are affected by the interaction between the genotype of the species and the ecological factors of the production area, which can be reflected in the climate-dominated type, production measure-dominated type, or germplasm-dominated type. According to the natural, material, and medicinal attributes of Dao-di herbs, model organisms such as Salvia miltiorrhiza can be constructed, and the research methodology system of the characteristics of "excellent shape, high quality, and superior effect" can be established, including quality evaluation system based on "high quality", characterization methodology system of "property-efficacy relationship", and homeostatic comprehensive control system based on "excellent shape and high quality". In the future, research on Dao-di herbs should pay more attention to in-depth and extensive basic work, and it is necessary to establish a comprehensive medicinal model plant research platform and build a medicinal model plant mutant library, so as to provide powerful model organisms for the functional gene research of other plants. Meanwhile, three research hotspots have been proposed for the research on the characteristics of "excellent shape, high quality, and superior effect" of Dao-di herbs, so as to reveal the mechanisms of their genetic basis, biological characteristics, and ecological adaptability. These studies will provide a scientific basis for optimizing the directed breeding of medicinal plants, standardizing cultivation, and improving the quality of medicinal herbs, so as to promote the sustainable use and development of Dao-di herbs.

RESUMEN

Introducción: Entre 0,3-0,5% de niños nacidos presentan una vena cava superior izquierda persistente, lo que lo hace una de las malformaciones congénitas más frecuentes del drenaje venoso. El drenaje de esta en la aurícula derecha, además del drenaje de la vena cava superior derecha en la aurícula izquierda, es extremadamente infrecuente. Caso Clínico: Se presenta el caso de un infante de 8 meses asintomático que es llevado a consulta por presentar desaturaciones. El examen físico es normal. El ecocardiograma de contraste con solución salina muestra una vena cava superior izquierda persistente que drena en la aurícula derecha y un retorno anómalo de la vena cava superior derecha. Se realiza una corrección quirúrgica y evoluciona de forma favorable. Conclusión: La presentación en simultáneo de una vena cava superior izquierda persistente que drena en la aurícula derecha y una vena cava derecha que drena en la aurícula izquierda es extremadamente rara. La mayoría de los casos registrados se diagnosticaron de manera incidental en personas adultas al no presentar síntomas.

Introduction: Between 0.3-0.5% of children born have a persistent left superior vena cava, which makes it one of the most frequent congenital malformations of venous drainage. Drainage of this vein into the right atrium, in addition to drainage of the right superior vena cava into the left atrium, is extremely rare. Clinical case: We present a case of an asymptomatic 8-month-old infant who was taken to the clinic for desaturations. Physical examination was normal. The contrast echocardiogram with saline solution showed a persistent left superior vena cava draining into the right atrium and an anomalous return of the right superior vena cava. Surgical correction was performed and the patient evolved favorably. Conclusion: The simultaneous presentation of a persistent left superior vena cava draining into the right atrium and a right superior vena cava draining into the left atrium is extremely rare. Most of the reported cases were diagnosed incidentally in adults in the absence of symptoms.

RESUMEN

BACKGROUND: Graft failure is a common complication after superior capsule reconstruction (SCR). The graft in SCR is fixed on the greater tuberosity and superior glenoid, and graft failure has been reported on both sides. PURPOSE: To evaluate the clinical manifestations of patients with graft failure after SCR and identify the clinical and radiological differences between medial and lateral graft failure. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients who underwent SCR with a dermal allograft for symptomatic irreparable rotator cuff tears between March 2018 and September 2021 were retrospectively reviewed. All patients had minimum 2-year follow-up and underwent magnetic resonance imaging at 6 months postoperatively. Patients with graft failure were divided into 2 groups: those with lateral graft failure on the greater tuberosity side (group I) and those with medial graft failure on the glenoid side (group II). Patients with intact grafts were included in group III as a control group. Intergroup differences in clinical and radiological characteristics were analyzed, and multiple regression analysis was performed. RESULTS: Among the 93 patients included, there were 18 patients in group I, 15 in group II, and 60 in group III. Overall, 11 patients (61.1%) in group I and 9 patients (60.0%) in group II had a partial graft rupture at one anchor. The postoperative graft volume was significantly lower in group I than in groups II and III (2514.0 ± 564.3 mm3, 3183.5 ± 547.1 mm3, and 3198.0 ± 584.8 mm3, respectively; P = .002 for group I vs II; P < .001 for group I vs III). The acromiohumeral distance (AHD) was significantly increased at 6 months postoperatively compared with before surgery in group I (6.6 ± 1.6 mm vs 4.3 ± 1.9 mm, respectively; P < .001) and group II (7.4 ± 1.3 mm vs 5.7 ± 1.7 mm, respectively; P = .002). However, group I exhibited a significantly greater decrease in the AHD over time than group II (P < .001) and a significantly lower AHD at the final follow-up than the other groups (P < .001). The postoperative American Shoulder and Elbow Surgeons score was significantly lower in group I than in the other groups (P < .001). On multiple regression analysis, fatty infiltration of the infraspinatus muscle, Hamada grade, and graft width were independent factors for lateral graft failure. CONCLUSION: Patients with lateral graft failure had inferior clinical outcomes and lower postoperative graft volumes than those with medial graft failure after SCR using a dermal allograft. The AHD of patients with lateral graft failure improved postoperatively; however, it deteriorated over time.

RESUMEN

The superior colliculus (SC) receives inputs from various brain regions in a layer- and radial subregion-specific manner, but whether the SC exhibits subregion-specific dynamics remains unclear. To address this issue, we recorded the spiking activity of single SC neurons while photoactivating cortical areas in awake head-fixed Thy1-ChR2 rats. We classified 309 neurons that responded significantly into 8 clusters according to the response dynamics. Among them, neurons with monophasic excitatory responses (7-12 ms latency) that returned to baseline within 20 ms were commonly observed in the optic and intermediate gray layers of centromedial and centrolateral SC. In contrast, neurons with complex polyphasic responses were commonly observed in the deep layers of the anterolateral SC. Cross-correlation analysis suggested that the complex pattern could be only partly explained by an internal circuit of the deep gray layer. Our results indicate that medial to centrolateral SC neurons simply relay cortical activity, whereas neurons in the deep layers of the anterolateral SC dynamically integrate inputs from the cortex, SNr, CN, and local circuits. These findings suggest a spatial gradient in SC integration, with a division of labor between simple relay circuits and those integrating complex dynamics.

RESUMEN

This radiologic work aimed to display the alteration in the superior orbital fissure (SOF) morphology in the pediatric population with advancing age. This pediatric examination consisted of computed tomography images of 180 subjects (90 males/90 females) aged 1-18 years. The length (SOF-L) and width (SOF-W) of SOF were measured, and its shape was noted. SOF-L and SOF-W were measured as 16.04 ± 2.34 mm and 5.35 ± 1.01 mm, respectively. SOF-L was similar in infancy and early childhood periods, but then decreased up to postpubescent period. This measurement increased significantly in postpubescent period. SOF-W did not show important change from infancy period up to postpubescent period. After that, it increased significantly in postpubescent period. Seven configurations regarding SOF shape were observed: the straight type in 20.8% out of 360 SOFs, eight-shaped type in 12.2%, key-shaped type in 14%, racket-shaped type in 18.6%, narrow type in 7.2%, triangular type in 14.7%, and curved type in 12.5%. SOF shape was not affected by sex (p = 0.150) and side (p = 0.919). Linear functions were calculated as y = 16.310-0.028 × age for SOF-L, and as y = 4.886 + 0.048 × age for SOF-W. SOF-L showed an irregular pattern of first decreasing and then increasing, during the transition from 1 year to 18 years. SOF-W displayed an irregular pattern of increasing with advancing ages in children. Our linear functions representing the growth pattern of SOF in children may be useful to estimate SOF size.

RESUMEN

Purpose: To compare the surgical outcomes of One- versus Two-vertical muscle surgery in patients with unilateral superior oblique muscle palsy (SOP) with primary position hypertropia (HT) over 20 PD. Patients in Group 1 underwent inferior oblique anterior transposition plus resection (IOATR), while patients in Group 2 underwent inferior oblique anterior transposition (IOAT) along with contralateral inferior rectus (IR) recession. Methods: Medical data of all SOP patients treated by either procedure from 2000 to 2023 in our strabismus center were recruited. We compared surgical outcomes between Group 1 and Group 2 by analyzing HT correction, rate of under-correction, and over-correction. Results: The study included 33 patients in Group 1 and 23 in Group 2. Both groups were similar in age, sex, etiology, affected side, diplopia, and head tilt. Group 2 achieved higher HT correction in all measured gazes. Group 1 had a higher risk of under-correction (18.18% in Group 1 vs 8.69% in Group 2) while Group 2 had a higher rate of over-correction (21.73% vs 0% in Group 1). Conclusion: In patients with severe unilateral SOP, Two-vertical muscle surgery achieved higher amounts of HT correction in all gazes despite a significantly higher risk of over-correction.

RESUMEN

Surgery which involves anterior mediastinal mass resection with artificial replacement of the superior vena cava results in significant disruption to the circulatory system. In this case, a pathway was established to divert blood from the internal jugular to the femoral vein after clamping of the superior vena cava. Blood which would ordinarily return to the right atrium via the superior vena cava was now being returned via the inferior vena cava. The mean arterial pressure was maintained at least 50 mmHg higher than the central venous pressure during clamping of the superior vena cava to avoid cerebral hypoperfusion. The combined use of the above strategies aimed to provide satisfactory surgical conditions and cerebral protection.

RESUMEN

COVID-19 patients may experience acute mesenteric ischaemia. Identifying acute mesenteric ischaemia is challenging, particularly as initial symptoms are often vague and easily overlooked. Early detection and immediate intervention to restore blood flow can prevent these severe consequences. Presented in this report are two cases of superior mesenteric artery (SMA) thrombosis following severe acute respiratory syndrome coronavirus 2 infection. CT scans demonstrated SMA thrombosis in both patients, with no evidence of bowel necrosis. Endovascular intervention with self-expanding stent placement was performed after angiographic confirmation of the diagnosis. At 6-month follow-up, both patients remained asymptomatic on dual antiplatelet therapy. Atypical gastrointestinal manifestations in COVID-19 patients should raise suspicion for uncommon complications, such as SMA thrombosis. For SMA occlusion without associated bowel necrosis, endovascular therapy represents a viable treatment approach.

RESUMEN

Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is a rare condition resulting from compression of the third portion of the duodenum between the aorta and the superior mesenteric artery. When symptomatic, this compression may result in nausea, vomiting, epigastric discomfort, and weight loss, requiring clinical attention and imaging to make the diagnosis. Typically, SMA syndrome presents in young females and is associated with an underlying condition such as anorexia nervosa, cachexia, postoperative development after scoliosis surgery, etc. In this report, we present the case of an atypical delayed presentation of SMA syndrome in an 84-year-old male who had epigastric pain, nausea, intermittent vomiting, and a 30-pound weight loss over two years. SMA syndrome was diagnosed on a computed tomography (CT) scan by a decreased angle between the superior mesenteric artery and abdominal aorta, and treatment with a robotic-assisted strong procedure was performed. The patient was followed postoperatively in the clinic and tolerated the procedure well.

RESUMEN

Superior vena cava (SVC) syndrome is a constellation of symptoms that occur secondary to external compression of the SVC, most commonly by a mediastinal malignancy. With the increased use of implanted cardiac devices and indwelling central venous catheters, SVC syndrome from a benign cause has become quite common. This report follows a 62-year-old female who was initially admitted to the critical care unit for treatment of angioedema without a history of malignancy but was found to have a surgically placed port used to treat her rheumatoid arthritis. Despite treatment of what was presumed to be angioedema, her symptoms failed to resolve. Imaging of the thorax revealed a venous thrombosis in the previously placed port. The port was subsequently removed, and the patient's symptoms hastily resolved. This case report underscores the importance of obtaining a thorough history, maintaining a broad differential diagnosis, and revising the differential when the patient's symptoms fail to improve.

RESUMEN

BACKGROUND: The majority of studies on parasagittal dural arteriovenous fistulas (DAVFs) have been limited to case reports or case series, and they are frequently reported alongside true superior sagittal sinus (SSS) DAVFs. Because of the selective bias present in the reporting of dispersed small numbers of parasagittal DAVFs, the results of each study may influence the findings. As a result, we present a large sequential cohort of parasagittal DAVFs from our institution spanning a 20-year period. METHODS: This study was a retrospective analysis involving 80 patients with parasagittal DAVFs who were hospitalized at a single medical center from 2002 to 2022. We explore their clinical manifestations, angioarchitecture, clinical and radiographic outcomes. RESULTS: We identified 80 patients with 85 parasagittal DAVFs. The cohort consisted of 69 men and 11 women, with a M ± SD age of 50.5 ± 11.1 years. Seventy-six patients underwent trans-arterial embolization (TAE), two underwent surgery, and two received conservative treatment. Immediate complete occlusion was achieved in 74 cases (94.9%). Fifty (96.2%) patients were cured, with no recurrence detected on final follow-up imaging. One patient died 6 months after the final subtotal occlusion, while the other patients experienced improvement or resolution of clinical symptoms following treatment. CONCLUSIONS: These lesions carry a high risk of hemorrhage and nonhemorrhagic neurological deficits. In our series, TAE achieved a high cure rate for these lesions, with no major complications reported.

RESUMEN

OBJECTIVES: Our study aimed to evaluate the effect of superior hypogastric nerve plexus (SHNP) block in postoperative pain management in the first 24 h after minimally invasive gynecological (MIG) surgeries. METHODS: We conducted a double-blinded, randomized controlled trial in the Department of Obstetrics and Gynecology at a tertiary care centre from May 1, 2023 to September 30, 2023 in women undergoing major MIG surgeries. At the completion of the surgery, women were randomized to the intervention group who received SHNP block with ropivacaine 10 mL (0.75%) before port removal, whereas no intervention was taken in the control group. The extubation time was noted, and the pain score was assessed after 1, 2, 6, 12, and 24 h of extubation in the postoperative period using the visual analog scale (VAS). Statistical analysis was done, with a significance level of 0.05, to test the differences between the two groups. RESULTS: A total of 64 patients were randomly allocated to intervention and control groups. The median pain score was lower at 1 and 2 h post-extubation and comparable between the two groups at 6, 12, and 24 h. The surrogate markers that is need for additional analgesia and duration of stay did not differ significantly in the two groups, with P-values of 0.08 and 0.943, respectively. CONCLUSION: Although the SHNP group experienced considerably lower immediate postoperative pain levels in the initial hours following extubation, the impact of this benefit remains uncertain in the longer postoperative period. The effectiveness of this modality for pain control needs further study, particularly at later postoperative hours.

RESUMEN

This study investigates the challenges and repercussions of Emergency Remote Learning (ERL) on the education of Nutrition students at a public university in Rio Grande do Norte, with a particular focus on Public Health education, from the perspective of faculty members. ERL was implemented due to the COVID-19 pandemic, directly impacting the quality of education, especially in health-related courses that require hands-on practices. The research employed a qualitative approach, using semi-structured interviews with faculty members who teach Public Health-related subjects. The results indicate that, despite the teachers' efforts to adapt their methodologies to the virtual environment, significant challenges were encountered, such as low student participation and technical difficulties. Furthermore, the lack of in-person interaction hindered practical training and the development of essential skills for professional practice within the Unified Health System (SUS). The conclusions emphasize the importance of in-person learning in Public Health and the need to reconsider the role of Information and Communication Technologies (ICTs) in health education.

RESUMEN

Objectives: To investigate the factors associated with the willingness to know the serological status for syphilis among higher education students. Methods: A cross-sectional and analytical study was conducted with higher education students in Portugal. Data collection was carried out through an online questionnaire. The data were analyzed using Poisson logistic regression with robust variance, utilizing SPSS-24. Results: A total of 413 students were included, the majority of whom were female, with an average age of 20.5 years, and enrolled in health-related courses. Behavioral vulnerabilities such as not using condoms and using alcohol/other drugs were observed; there was also a low-risk perception and poor knowledge about syphilis. Less than half of the students were willing to undergo the syphilis test. Conclusions: Adherence to syphilis screening was low and associated with uncommon factors such as lower knowledge, low risk perception, younger age, fewer sexual partnerships, and enrollment in courses outside the health field.

RESUMEN

Superior vena cava syndrome (SVCS) is commonly caused by mediastinal malignancies. Early identification through clinical signs and imaging is critical to avoid complications including cerebral and laryngeal edema, and cardiogenic shock. We present a case of large cell neuroendocrine carcinoma causing superior and inferior vena cava compression that responded well to radiotherapy and chemotherapy.

RESUMEN

Superior mesenteric artery (SMA) syndrome causes duodenal obstruction between the SMA and aorta, which culminates into bowel obstruction. Meanwhile, nutcracker syndrome (NCS) involves left renal vein compression between the aorta and SMA, categorized by the compression site. We present a 15-year-old female with no prior medical or surgical history who displayed early signs of the rarely coexisting SMA and nutcracker phenomena, which were managed symptomatically along with nutritional support to reach her optimal body mass index.

RESUMEN

BACKGROUND: Transcatheter radiofrequency ablation is one of the main treatments for atrial fibrillation, but related complications of this surgery are uncommon. CASE PRESENTATION: Here, we report a 70-year-old elderly male patient with atrial fibrillation who experienced severe abdominal pain early after undergoing radiofrequency ablation; related imaging examinations suggested that the patient had intestinal edema and thickening, combined with hepatic portal vein gas accumulation. The reason was that the patient experienced intestinal necrosis due to superior mesenteric artery embolism related to radiofrequency surgery. The surgeon suggested laparotomy for exploration. However, after multidisciplinary consideration, we ultimately chose conservative treatment. After fasting, gastrointestinal decompression, spasmolysis, pain relief, somatostatin inhibition of intestinal edema, antiinfection, and anticoagulation, the patient's condition improved, and he was discharged. We followed the patient for 1 month after discharge, and there was no special discomfort. CONCLUSION: Hepatoportal vein gas accumulation after radiofrequency ablation of atrial fibrillation is rare, and imaging findings have important guiding significance for the diagnosis and treatment of the disease.
