Bridging Visual-Spatial Ability and Skill Performance: The Impact of Perceived Quality of a Practical Seminar in Interventional Radiology Education.

Background: Medical education integrates skills training and simulation to prepare students for clinical tasks. A seminar on interventional radiology was restructured to include specific practical training utilizing a 3D-catheter model. We aimed to investigate the complex interplay between student evaluations, their visual-spatial ability and practical performance.

Virtual reality for assessing emergency medical competencies in junior doctors - a pilot study.

Background: The teaching and assessment of clinical-practical skills in medical education face challenges in adequately preparing students for professional practice, especially in handling emergency situations. This study aimed to evaluate the emergency medical competencies of junior doctors using Virtual Reality (VR)-based scenarios to determine their preparedness for real-world clinical situations.

Methods: Junior doctors with 0-6 months of professional experience participated in one of three VR-based emergency scenarios.

Digital analysis of the human maxilla to enable semistandardized template tool reconstructions with free fibula transplants.

Objectives: This study analyzed the human maxilla to support the development of mean-value-based cutting guide systems for maxillary reconstruction, bridging the gap between freehand techniques and virtual surgical planning (VSP).

Materials And Methods: This retrospective cohort study used routine CT scans. DICOM data enabled 3D modelling and the maxilla was divided into four regions: paranasal (R1), facial maxillary sinus wall (R2), zygomatic bone (R3) and alveolar process (R4).

The interplay of stress and work-related musculoskeletal disorders in dental practitioners.

Objectives: Prevalence of work-related musculoskeletal disorders (WRMSDs) among general dental practitioners and orthodontists is approximated to range between 64% and 93%. Etiology of WRMSDs in the mentally and physically demanding occupation remains unclear, for which reason the aim of the study was to clarify the interplay of physical, psychological, and mental factors on WRMSDs.

Method And Materials: Of 94 orthodontists and 187 general dental practitioners (mean age = 35 years) questioned using an online survey, 84% reported persisting tension or pain in the back, neck, or shoulders.

Clustering of Gastrointestinal Microorganisms in Human Stool Samples from Ghana.

The study was conducted to identify cluster patterns of enteric microorganisms with potential etiological relevance for infectious gastroenteritis in stool samples of individuals from Ghana, which is a known high-endemicity setting for infectious gastroenteritis. These patterns were compared to previous observations with specimens from Colombian indigenous people in order to assess potentially stable clustering for temporally and spatially distinct populations from high-endemicity regions. By doing so, the study aimed to identify stable clusters as markers of microbial interaction with potential importance for etiological relevance assignment in cases of multiple enteric pathogen detections.

Improved Learning Gain in Medical Students by Using Animated Whiteboard-Videos in Comparison to Textbooks in Surgery.

Background: Animated videos have become popular in teaching medical students, although there is a certain lack of evidence concerning its efficacy. Surgery seems to be an ideal field for its application, since animations are very helpful to understand anatomic structures and complex procedures. The aim of this study was to investigate the effects of animated videos compared to textbooks on learning gain.

Collider Bias Assessment in Colombian Indigenous Wiwa and Kogui Populations with Chronic Gastroenteric Disorder of Likely Infectious Etiology Suggests Complex Microbial Interactions Rather Than Clear Assignments of Etiological Relevance.

Multiple microbial detections in stool samples of indigenous individuals suffering from chronic gastroenteric disorder of a likely infectious origin, characterized by recurring diarrhea of variable intensity, in the rural north-east of Colombia are common findings, making the assignment of etiological relevance to individual pathogens challenging. In a population of 773 indigenous people from either the tribe Wiwa or Kogui, collider bias analysis was conducted comprising 32 assessed microorganisms including 10 bacteria ( spp., spp.

Chagas Disease: Comparison of Therapy with Nifurtimox and Benznidazole in Indigenous Communities in Colombia.

: For indigenous people in Colombia, high infection rates with Chagas disease (CD) are known. : In 2018 and 2020, nine villages were screened for CD. CD-positive patients could enter a drug observed treatment.

[Repetitio est mater studiorum-implementation of ENT cases in case-based e-learning].

Background: German university otorhinolaryngology has a need for digital teaching content. Case-based e‑learning represents a digital teaching methodology. The data on student use of case-based e‑learning in university teaching of ENT medicine are limited.

Gastrointestinal Pathogens in Multi-Infected Individuals: A Cluster Analysis of Interaction.

Indigenous people live in remote areas of Colombia. Multiple infections with bacteria, protozoa and/or helminths are common, as well as colonization in various forms. This study focused on the question of whether and to what extent various pathogens interact with each other.

Tablet-based versus presentation-based seminars in radiology: Effects of student digital affinity and teacher charisma on didactic quality.

Aims: Tablets are being adopted as teaching medium in medical education more frequently. Here we compared two teaching formats in a radiology seminar using a tablet-based student-centred approach guided by teachers and traditional presentation-based, teacher-centred instruction. The aim was to investigate the effects on academic performance, estimated learning gain, didactic quality, as well as how teacher charisma and student digital affinity influence these elements.

Students' perception of three-dimensionally printed teeth in endodontic training.

Introduction: In endodontic education, there is a need for thorough training prior to students embarking on clinical treatment. The aim of this study was to use three-dimensional printing technology to create a new model and to compare its suitability for training purposes with resin blocks and extracted teeth.

Materials And Methods: Multi-jet-modelling (MJM) produced the 3D model replicating a common difficulty in root-canal morphology.

High Prevalence of Intestinal Pathogens in Indigenous in Colombia.

Background: Intestinal infections remain a major public health burden in developing countries. Due to social, ecological, environmental, and cultural conditions, Indigenous peoples in Colombia are at particularly high risk.

Materials: 137 stool samples were analyzed by microscopy and real-time-Polymerase Chain Reaction (RT-PCR), targeting protozoan parasites ( spp.

Digital Affinity in Medical Students Influences Learning Outcome: A Cluster Analytical Design Comparing Vodcast With Traditional Lecture.

Background/objective: Undergraduate medical education still relies on lectures as the core teaching activity. However, e-learning and new media have begun to augment learning and information gathering over the last few years. The aim of this study was to investigate the effect of 2 teaching formats in surgical education, a classic lecture and a video podcast (vodcast), on knowledge gain, in particular with respect to the participants' characteristics and preferences.

Assessment of Health-Related Quality of Life after TBI: Comparison of a Disease-Specific (QOLIBRI) with a Generic (SF-36) Instrument.

Psychosocial, emotional, and physical problems can emerge after traumatic brain injury (TBI), potentially impacting health-related quality of life (HRQoL). Until now, however, neither the discriminatory power of disease-specific (QOLIBRI) and generic (SF-36) HRQoL nor their correlates have been compared in detail. These aspects as well as some psychometric item characteristics were studied in a sample of 795 TBI survivors.
