Abstract: Background: Septoplasty and rhinoplasty are difficult operations to learn and teach. Many modalities have been proposed to make the teaching process of these operations easier. In this study, it was investigated if lamb heads were good training models to teach septoplasty and rhinoplasty to trainees or experienced surgeons. Methods: In the first part of the study, 21 lamb heads were dissected according to a dissection protocol and several anatomical distances were measured in order to compare them with human cadavers. In the second project 8 lamb heads were dissected and different preservation rhinoplasty techniques were practiced. Results: The study on 21 lamb heads used showed that the lateral crura were 17.8 x 11.6, average interdomal distance was 8.1 mm, average domal width was 3.7 mm. The average length of the upper lateral cartilages was 31.1 mm laterally and 21.2 medially. The average length of the nasal bones was 63.9 mm and the width was 16 mm. In the second part of the study 8 lamb heads were used to experience where high strip techniques were used in 5 and Cottle technique in 3. Conclusion: This study revealed that lamb head should be considered as an excellent training model for septoplasty and rhinoplasty. Its very low cost, ease of availability, and close similarity to the human cadavers can be counted as the main advantages. This study also proved that it was not only a tool for beginners, but also a very helpful tool for experienced surgeons to try new methods.

Objectives: Currently, ultrasound (US) is widely used for the diagnosis of giant cell arteritis (GCA). Our aim was to develop a low-cost US training model for diagnosis of GCA of the temporal and axillary artery using a modern 3D printing system. Methods: We designed an US training model, which enables measurement of the intima-media thickness (IMT) of temporal and axillary arteries using Autodesk Fusion360. This model was printed using a modern 3D printer (Formlabs Form3) and embedded in ballistic gelatine. The ultrasound images including measurement of the IMT by ultrasound specialists in GCA were compared to ultrasound images in acute GCA and healthy subjects. Results: Our ultrasound training model of the axillary and temporal artery displayed a very similar ultrasound morphology compared to real US images and fulfilled the OMERACT ultrasound definitions of normal and pathological temporal and axillary arteries in GCA. The IMT measurements were in line with published cut-off values for normal and pathological IMT values in GCA and healthy individuals. When testing the models on blinded US specialists in GCA, they were identified correctly in all test rounds with an intra-class coefficient of 0.99. Conclusion: The production of low-cost ultrasound training models of normal and pathological temporal and axillary arteries in GCA, which fulfil the OMERACT ultrasound definitions and adhere to the published IMT cut-off values in GCA, is feasible. Ultrasound specialists identified each respective model correctly in every case.

Abstract Background Benchtop microsurgical training models that use digital tools (smartphones, tablets, and virtual reality [VR]) for magnification are allowing trainees to practice without operating microscopes. This systematic review identifies existing microscope-free training models, compares models in their ability to enhance microsurgical skills, and presents a step-by-step protocol for surgeons seeking to assemble their own microsurgery training model. Methods We queried PubMed, Embase, and Web of Science databases through November 2020 for microsurgery training models and performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We collected data including training model characteristics (cost, magnification, and components) and outcomes (trainee satisfaction, image resolution, and faster suturing speed). We also conducted a complimentary Google search to identify commercially available microscope-free microsurgical training models or kits not reported in peer-reviewed literature. Results Literature search identified 1,805 publications; 24 of these met inclusion criteria. Magnification tools most commonly included smartphones (n = 10), VR simulators (n = 4), and tablets (n = 3), with magnification ranging up to ×250 magnification on digital microscopy, ×50 on smartphones, and ×5 on tablets. Average cost of training models ranged from $13 (magnification lens) to $15,000 (augmented reality model). Model were formally assessed using workshops with trainees or attendings (n = 10), surveys to end-users (n = 5), and single-user training (n = 4); users-reported satisfaction with training models and demonstrated faster suturing speed and increased suturing quality with model training. Five commercially available microsurgery training models were identified through Google search. Conclusion Benchtop microsurgery trainers using digital magnification successfully provide trainees with increased ease of microsurgery training. Low-cost yet high magnification setups using digital microscopes and smartphones are optimal for trainees to improve microsurgical skills. Our assembly protocol, “1, 2, 3, Microsurgery,” provides instructions for training model set up to fit the unique needs of any microsurgery trainee.

Youth Athlete

Context: Most available data on athletic development training models focus on adult or professional athletes, where increasing workload capacity and performance is a primary goal. Development pathways in youth athletes generally emphasize multisport participation rather than sport specialization to optimize motor skill acquisition and to minimize injury risk. Other models emphasize the need for accumulation of sport- and skill-specific hours to develop elite-level status. Despite recommendations against sport specialization, many youth athletes still specialize and need guidance on training and competition. Medical and sport professionals also recommend progressive, gradual increases in workloads to enhance resilience to the demands of high-level competition. There is no accepted model of risk stratification and return to play for training a specialized youth athlete through periods of injury and maturation. In this review, we present individualized training models for specialized youth athletes that (1) prioritize performance for healthy, resilient youth athletes and (2) are adaptable through vulnerable maturational periods and injury. Evidence Acquisition: Nonsystematic review with critical appraisal of existing literature. Study Design: Clinical review. Level of Evidence: Level 4. Results: A number of factors must be considered when developing training programs for young athletes: (1) the effect of sport specialization on athlete development and injury, (2) biological maturation, (3) motor and coordination deficits in specialized youth athletes, and (4) workload progressions and response to load. Conclusion: Load-sensitive athletes with multiple risk factors may need medical evaluation, frequent monitoring, and a program designed to restore local tissue and sport-specific capacity. Load-naive athletes, who are often skeletally immature, will likely benefit from serial monitoring and should train and compete with caution, while load-tolerant athletes may only need occasional monitoring and progress to optimum loads.

ABSTRACT - This review highlights the advantages and current status of plant-derived vaccine development with special reference to the dengue virus. There are numerous problems involved in dengue vaccine development, and there is no vaccine against all four dengue serotypes. Dengue vaccine development using traditional approaches has not been satisfactory in terms of inducing neutralizing antibodies. Recently, these issues were addressed by showing a very good response to inducing neutralizing antibodies by plant-derived dengue vaccine antigens. This indicates the feasibility of using plant-derived vaccine antigens as a low-cost method to combat dengue and other infectious diseases. The application of new methods and strategies such as dendritic cell targeting in cancer therapy, severe acute respiratory syndrome, tuberculosis, human immune deficiency virus, and malaria might play an important role. These new methods are more efficient than traditional protocols. It is expected that in the near future, plant-derived vaccine antigens or antibodies will play an important role in the control of human infectious diseases.

Meta Analyses

Studies assessed the beneficial effects of aerobic exercise on blood pressure (BP); however, few studies have evaluated the effects of long-term resistance training on variations of this response. The aim of the study was to verify through a systematic review, the long-term effect of resistance training on BP. Searches were made on Medline through Pubmed, Science Direct, Scopus, Web of Science and Lilacs databases. Overall, 751 articles were found, of which 22 were further analyzed. The analysis followed the PRISMA checklist (Statement for Reporting Systematic Reviews and Meta-Analyses of Studies) and was divided according to two resistance training models: traditional resistance training (TRT), resistance training alone; or combined resistance training (CRT), resistance training associated with aerobic exercise. Greater BP reductions occurred for CRT compared to TRT. However, further studies are needed to better explicit the resistance training variables (number of exercises, repetitions, number of sets, intervals, speed of execution and load intensity), in order to identify the best training model and improve the methodological quality of experiments in an attempt to reduce the risk of bias.

Agriculture is one of the fields that still dominates Indonesia as an agricultural country. As a substantial actor in agriculture, many farmers have not met their daily needs. This study examines the quality of alternative business training models for farmworkers using a community empowerment system. This study is part of research and development focused on product quality testing. The training model that the researcher has designed is then tested on validity, practicality, and effectiveness. The participants involved in this study were farm labourers in 2 sub-districts in Wajo Regency, South Sulawesi, Indonesia, namely Pammana and Tanasitolo sub-districts as many as 15 farm workers, two observers, and three agricultural experts. Furthermore, the instruments used in this study were: (1) validation sheet, (2) model implementation observation sheet, (3) farmworker response questionnaire, and (4) knowledge test. The data that has been collected is then analyzed quantitatively using SPSS 23.00 software. The study results show that the training model that this researcher has designed is valid, practical, and effective in increasing the knowledge of farmworkers and can be used for a broader range of users.

Research Findings

This paper outlines briefly, some views of the term “ Educational Technology” and its role generally in the field of education as evident from research findings. The urgent need for low-cost educational technology for schools and colleges in Nigeria is discussed. Attention is also drawn to the need to re-orient the teacher to his task, if new methods and media are to be used successfully. Finally, it is further suggested that future use of the achieved methods and media may differ radically depending among other things on the objectives to be achieved and the en­try behaviour of the students, particularly when we employ the low-cost educational technology for effective learning hnd teaching. The importance of an Educational Resource Centre, and Teachers’ Resource Centre are among other things strongly suggested.

Postpartum haemorrhage remains a leading cause of maternal mortality and morbidity. While conventional obstetrics training curricula describe at length the management of postpartum haemorrhage, obstetrics trainees rarely have exposure to surgical management of postpartum haemorrhage in emergency situations due to reduced hours of training. Procedures such as the transverse or longitudinal haemostatic uterine brace sutures are recognised to be safe, simple and allow for the preservation of the uterus. Training during emergency situations is rarely practical or ideal. We describe a simple model that simulates the atonic postnatal uterus and allows trainees to practise the safe placement of the brace sutures. We use a bovine uterus model with attached broad ligament, bladder and ureters for the transverse haemostatic suture. For the longitudinal brace suture, we use a porcine bladder to simulate the uterus, with the ureters and bladder mesentery simulating the tubes and broad ligaments. The placement of the sutures can be practised with the uterus/bladder closed, or open akin to a caesarean section. Tissue dissection and feedback is almost similar to in vivo conditions. The sutures are inserted and driven using the material and correct placement used during real surgery. Our wet lab training model allows the acquisition, maintenance and enhancement of the required technical skills in a controlled environment, using inexpensive, reproducible and widely available specimens. The model has proved successful in both high and low-resource healthcare settings.
