Self-perception of the acquisition of transferable competencies by the participants in a research congress for undergraduate students: A cross-sectional study.

Context: Several curricular initiatives have been developed to improve the acquisition of research competencies by Health Science students. Objectives: To know how students self-perceived of whether their participation in the XIV National Research Congress for Undergraduate Students of Health Sciences had helped them in the acquisition of 36 research-related transferable competencies (TCs) common to Health Science degrees. Methods: A survey design (Cronbach's alpha = 0.924), using a self-administered questionnaire, was conducted among undergraduate students who voluntarily participated in the Congress. Data analysis was performed using SPSS 25 and Statgraphics 19. Statistical significance was considered for P < 0.05. Results: Eighty-one students from 12 Health Science degree programs responded. Key findings are presented in a structured manner, using a Likert-5 scale. Twenty-five of the competencies surveyed obtained an average ≥ 4 highlighting: "Critically evaluate and know how to use sources of clinical and biomedical information to obtain, organize, interpret, and communicate scientific and health information"; "To be able to formulate hypotheses, collect and critically evaluate information for problem solving, following the scientific method", "Critical analysis and research" and "Communicate effectively and clearly, orally and in writing with other professionals". Significance was found in 15 competencies. The development of the competencies "Teamwork", "Critical reasoning" and "Analysis and synthesis abilities" was considered to be of greater "personal utility" by the respondents. Conclusion: Participation in this event contributed to the development of research-related TCs, critical analysis and information management and communication, especially in relation to learning the sources of clinical and biomedical information, to know, following the scientific method, how to formulate hypotheses that allow students to solve problems in their professional activity. The experience was significantly influenced by the respondents' year, the type of participation in the event and the gender of the students. Limitations and suggestions regarding future research are discussed to encourage further exploration of the topic.

Latin American Anatomists' views on human body dissection and donation.

BACKGROUND: Studies abound regarding the medical students' views on the importance of anatomy and the dissection of human bodies, but little is known about the views of Latin American Anatomists. METHODS: A survey was carried out to test several hypotheses among anatomists of the Americas about how they perceive their professional identity, the use and role of dissection in their undergraduate courses, and the approval degree of bequeathing their body for anatomical teaching/research; another goal was ascertaining to what extent their attitude on these topics depended on gender, length of teaching experience and belief in the afterlife. RESULTS: One hundred and forty-five anatomists from thirteen Latin American and Caribbean Countries took the survey; 79% stated the main role of an anatomist is teaching; 34% recorded their undergraduate students dissected human cadavers as part of their anatomy lab course-undergraduates dissecting less in the less experienced anatomists' courses (p = 0.0002). Most anatomists said dissection was a training tool for undergraduate students, a tool for developing professional skills, and a tool to help control emotions-most experienced anatomists stood out from the rest saying dissection is only to teach anatomy (p < 0.001), even if such response was the least valued by them among all replies. Men differed from women in valuing dissection as a tool to help control emotions (p = 0.006); less experienced anatomists held the opposite (p < 0.0001). Approval of a close doctor-patient relationship diverged, being different between the most and the least experienced anatomists (p = 0.01). Anatomists said they would donate only their organs (44%), whole body (9%) and both organs and body (46%). Undecided anatomists about the belief in life after death were the least in favor of donation (p = 0.05).

Physicians' viewpoints on faculty anatomists and dissection of human bodies in the undergraduate medical studies.

BACKGROUND: Studies abound regarding the views of faculty anatomists and medical students on the importance of anatomy and the dissection of human bodies, but very little is known about the views of practicing physicians. METHODS: A survey was distributed among physicians and surgeons practicing in Spain in order to find out their views on the practice and consequences of human dissection by undergraduate students of medicine. The most relevant definition to qualify faculty anatomists of medical schools was also requested. Responses were repeatedly clustered into characteristic subgroups for analysis. RESULTS: In total, 536 physicians and surgeons belonging to 36 different specialties in seven Spanish hospitals responded to the survey. The results highlighted two main facts. Firstly, faculty anatomists were perceived as teachers, above any other professional identity (namely: physician, biologist or scientist); nonetheless, the ascription of identities varied between specialties (p=0.009); and it also depended on whether the respondents had dissected in their undergraduate degree (p=0.03) and on the respondent's gender (p=0.03). Secondly, physicians and surgeons confirmed that dissecting human cadavers serves the undergraduate student not only for acquiring anatomical knowledge, but also essential skills and attitudes, including professionalism. CONCLUSIONS: The results strongly suggest that dissection practice should be reinforced and enriched in undergraduate medical school. As this is important in itself, the results of the study could also help with the development of strategies to alleviate the current shortage of adequately trained anatomists for medical degrees.

Development of the long head of the biceps brachial tendon: A possible explanation of the anatomical variations.

The anatomical variations of the proximal portion of the long head of the biceps brachii tendon (LHBT) are rarely observed in clinical practice. However, an increase in the rate of shoulder arthroscopic surgery has led to an increase in the observation of anatomical variations of this region. The aim of this work was to analyze the development of the LHBT in 23 human embryos ranging from the 6th to 8th weeks of development. The LHBT develops from the glenohumeral interzonal mesenchyme in the 6th week. By week 7, the myotendinous junction of the LHBT develops. The anlage of the LHBT is separated from that of the glenohumeral capsule during week 8. Our results suggest that the most important period for the LHBT development occurs between the 6th and 8th weeks of embryonic development. Alterations during this critical period may cause anatomical variations of the LHBT. An additional case report from our own experience is provided as Supplementary material.

Development of the Human Biceps Brachii Tendon and Coracoglenoid Ligament (7th-12th Week of Development).

The goal of this study is to clarify the development of the long head of the biceps brachii tendon (LHBT) and to verify the existence and development of the coracoglenoid ligament. Histological preparations of 22 human embryos (7-8 weeks of development) and 43 human fetuses (9-12 weeks of development) were studied bilaterally using a conventional optical microscope. The articular interzone gives rise to the LHBT, glenoid labrum, and articular capsule. During the fetal period, it was observed that in 50 cases (58%), the LHBT originated from both the glenoid labrum and the scapula, while in 36 cases (42%), it originated only from the glenoid labrum. The coracoglenoid ligament, first described by Sappey in 1867, is a constant structure that originates at the base of the coracoid process and projects toward the glenoid labrum zone, which is related to the origin of the LHBT. The coracoglenoid ligament was more easily identifiable in the 36 cases in which the LHBT originated only from the glenoid labrum. We suggest that the coracoglenoid ligament is a constant anatomical structure, is not derived from the articular interzone unlike the LHBT, and contributes to the fixation of the glenoid labrum in the scapula in cases in which the LHBT originated only from the glenoid labrum. We postulate that, when the LHBT is fixed only at the glenoid labrum, alterations in the coracoglenoid ligament could lead to a less sufficient attachment of the glenoid labrum to the scapula which could predispose to a superior labral lesion.

A Systematic Review of the Soft-Tissue Connections Between Neck Muscles and Dura Mater: The Myodural Bridge.

STUDY DESIGN: Systematic review. OBJECTIVE: To elucidate the existence of soft tissue connections between the neck muscles and cervical dura mater. SUMMARY OF BACKGROUND DATA: Several studies discuss the existence of a cervical myodural bridge; however, conflicting data have been reported. METHODS: Searches were conducted in the PubMed, Web of Science, Cochrane Library, and PEDro databases. Studies reporting original data regarding the continuity of non-post-surgical soft tissue between the cervical muscles and dura mater were reviewed. Two reviewers independently selected articles, and a third one resolved disagreements. Another two researchers extracted the methodology of the study, the anatomical findings, and evaluated the quality of the studies using Quality Appraisal for Cadaveric Studies Scale. A different third researcher resolved disagreements. RESULTS: Twenty-six studies were included. A soft tissue connection between the rectus capitis posterior minor, the rectus capitis posterior major, and the obliquus capitis inferior muscles seems to be proved with a strong level of evidence for each one of them. Controversy exists about the possible communication between the dura mater and the upper trapezius, rhomboideus minor, serratus posterior superior, and splenius capitis by means of the ligamentum nuchae. Finally, there is limited evidence about the existence of a soft tissue connection between rectus capitis anterior muscle and the dura mater. CONCLUSION: There is a continuity of soft tissue between the cervical musculature and the cervical dura mater; this might have physiological, pathophysiological, and therapeutic implications, and going some way to explaining the effect of some therapies in craniocervical disorders. LEVEL OF EVIDENCE: N/A.

[Schwannoma of the brachial plexus resembling a breast adenocarcinoma metastasis]. / Neurinoma del plexo braquial simulando metastasis de adenocarcinoma de mama.

Schwanomas originating from the brachial plexus, although rare, may be mistaken for another type of tumour. A 40 year-old woman, who had been treated years earlier for a breast adenocarcinoma, showed in the 5-year follow-up magnetic resonance examination a localized lesion in the right brachial plexus. The presumptive radiological diagnosis was a metastasis from the primary adenocarcinoma. Following surgical access via the right axilla, a well-circumscribed mass in the brachial plexus was detected. Under intraoperative electrophysiological guidance, the lesion was observed to depend on the ulnar nerve and its complete resection was possible without compromising nerve function. Histological findings indicated a schwannoma thus ruling out the presence of metastasis. The postoperative development was uneventful and six years after surgery, the patient is to date tumour-free. To the best of our knowledge, this is the first report of a brachial plexus schwannoma arising from the ulnar branch. Intraoperative electrophysiological monitoring is essential for a good surgical outcome.

Neurinoma del plexo braquial simulando metastasis de adenocarcinoma de mama / Schwannoma of the brachial plexus resembling a breast adenocarcinoma metastasis

Los neurinomas del plexo braquial son tumores infrecuentes que pueden confundirse con otras lesiones de índole tumoral. Se presenta el caso de una mujer de 40 años, tratada previamente de un adenocarcinoma de mama derecha en el pasado, que en el estudio de extensión realizado 5 años después se detectó una lesión localizada en el plexo braquial derecho. La paciente se encontraba asintomática. El diagnóstico radiológico de presunción fue metástasis de adenocarcinoma mamario. Se realizó un abordaje axilar derecho descubriendo una lesión bien delimitada en el plexo braquial. Con ayuda de la monitorización neurofisiológica intraoperatoria, se observó que la lesión dependía de la rama cubital y se pudo realizar una resección completa preservando la función de dicho nervio. El estudio anatomopatológico confirmó que se trataba de un neurinoma, descartando así la existencia de metástasis. La evolución postoperatoria fue satisfactoria. Seis años después de la intervención no existe recidiva tumoral. En nuestro conocimiento este es el primer caso publicado en la literatura de un neurinoma del plexo braquial dependiente de la rama cubital. La monitorización neurofisiológica intraoperatoria resulta fundamental para abordar este tipo de lesiones con baja morbilidad.

Dissection from the Spanish anatomist's perspective: aims, attitudes, and related aspects.

We present the results of a study conducted on participants of the 21st Congress of the Spanish Society of Anatomy, in which anatomists were asked their opinions about a range of issues related to anatomical dissection: its relative roles as the exclusive source of anatomy teaching, as a source for medical research, or to assist the future professional to acquire emotional control; the attitudes and behaviors they expect the student to have in the dissecting room; whether the student-cadaver relationship can convey knowledge and attitudes affecting the future doctor-patient relationship; and the anatomists' attitudes toward donation. Anatomists considered dissection to be mainly an instrument for professional training and to help develop professional skills. They gave little importance to the role it could play in helping students to control their emotions. However, this aspect was considered to be more important by anatomists who also valued a close doctor-patient relationship. On the other hand, a majority of anatomists felt that the student's attitude and behavior during dissection could be to some extent reflected in future relationships with patients. However, they did not feel that dissection-related attitudes would distinguish between future good or bad doctors. Finally, anatomy teachers are generally in favor of donation (86.5%), especially of organs alone (52.7%), and this aspect was not affected by their religious beliefs.
