Purpose: To systematically review the literature regarding low-cost, low-fidelity, self-made arthroscopic surgical simulators and provide an overview of their use in the teaching of arthroscopic surgical skills. Methods: Systematic review of the literature following PRISMA (Preferred Reporting Items for Systematic Reviews and MetaAnalyses) guidelines. Results: A total of 10 studies met inclusion criteria. All studies utilized low-cost, low-fidelity, self-made arthroscopic simulators of varying designs. Five studies (50%) utilized low-cost, self-made arthroscopic cameras and three (30%) utilized commercial surgical arthroscopic cameras. One study (10%) demonstrated face validity, five (50%) demonstrated construct validity, and three (30%) demonstrated transfer validity. The assessed arthroscopic tasks varied, but generally consisted of a combination of triangulation, object grasping, and tissue manipulation. Seven (70%) studies evaluated total simulator construction costs, with six (60%) studies achieving total construction costs of < $80 US Dollars. Conclusions: A growing body of literature supports the use of low-cost, low-fidelity, self-made arthroscopic surgical simulators. The cost-effectiveness and practicality of these simulators remains a major benefit to their overall utility when compared to their commercially available and high-fidelity counterparts. Furthermore, studies utilizing low-fidelity arthroscopic simulators are beginning to place a large importance on the achievement of face, construct, and transfer validity. Evidence suggests that the true utility of low-cost, low-fidelity arthroscopic surgical simulators stem not from their ability to replicate operating room conditions, but rather from their ability to provide practical training in basic and essential arthroscopic skills that will then be further refined through possible additional simulation and future surgical training.

ABSTRACT Background  Global health (GH) interest is increasing in graduate medical education (GME). The popularity of the GH topic has created growth in the GME literature. Objective  The authors aim to provide a systematic review of published approaches to GH in GME. Methods  We searched PubMed using variable keywords to identify articles with abstracts published between January 1975 and January 2015 focusing on GME approaches to GH. Articles meeting inclusion criteria were evaluated for content by authors to ensure relevance. Methodological quality was assessed using the Medical Education Research Study Quality Instrument (MERSQI), which has demonstrated reliability and validity evidence. Results  Overall, 69 articles met initial inclusion criteria. Articles represented research and curricula from a number of specialties and a range of institutions. Many studies reported data from a single institution, lacked randomization and/or evidence of clinical benefit, and had poor reliability and validity evidence. The mean MERSQI score among 42 quantitative articles was 8.87 (2.79). Conclusions  There is significant heterogeneity in GH curricula in GME, with no single strategy for teaching GH to graduate medical learners. The quality of literature is marginal, and the body of work overall does not facilitate assessment of educational or clinical benefit of GH experiences. Improved methods of curriculum evaluation and enhanced publication guidelines would have a positive impact on the quality of research in this area.

Abstract Introduction Perineal pressure associated with bicycle riding is the cause of several genitourinary pathologies, most notably Alcock’s syndrome and subsequent perineal numbness. The possible link between cycling-induced perineal numbness and erectile dysfunction makes the development of strategies for perineal protection in bicycle users critical. Objective To assess the effectiveness of strategies for reducing the impact of cycling on the perineum in healthy males. Methods We have conducted a systematic review and a meta-analysis of studies examining various means of reducing the impact of cycling on the perineum under the PRISMA guidelines. Results Out of 2217 screened studies, 22 met our inclusion criteria, and 6 qualified for meta-analysis. The strategies included various designs of saddles, changes in the cycling position, seat shock absorber, shorts with different padding, using the recumbent bike. Using the no-nose saddle and recumbent bike resulted in a significant reduction of perineal pressure and higher penile oxygen pressure compared with a standard saddle. Indirect evidence supports the protective effect of standing on the pedals every few minutes during cycling. More evidence is needed to support—or dismiss—other strategies. Conclusions Current evidence supports the use of no-nose saddles as a mean to reduce the negative impact of cycling on the perineum in healthy males at the cost of worse stability and increase of posterior seat pressure. Standing on the pedals every ten minutes might be an effective and potentially widely applicable strategy. The use of a recumbent bike appears to protect the perineum, but several concerns prevent its widespread use.

Background: Patient navigation (PN) programs have been shown to increase patient satisfaction and quality of life among patients with lung cancer and to decrease time to treatment. However, the general cost-effectiveness of such programs in the context of lung cancer remains unknown. Hence, the aim of the present systematic review was to analyze the scientific literature and quantitatively assess the level of evidence on the cost-effectiveness of PN programs for patients diagnosed with lung cancer.  Methods: A systematic literature search was carried out in PubMed, EMBASE, CENTRAL, CINAHL and PsycINFO databases without time limitations. Randomized controlled trials written in English or German were eligible for inclusion if any results regarding the cost-effectiveness of personally delivered PN programs for patients after lung cancer diagnosis were reported. A manual search was carried out to supplement the systematic search. Additionally, the authors of ongoing or unpublished relevant research were contacted. The titles, abstracts and full texts of relevant citations were screened independently by two reviewers.   Results: The initial search yielded 814 articles, including four papers identified manually. Twenty-one articles were included in the full text screening. However, no study met the inclusion criteria. Contacting the authors of ongoing or unpublished research and cross-cancer studies did not yield any studies that met the inclusion criteria.   Conclusion: Since no study met the inclusion criteria, this study reveals a research gap in this area. Furthermore, no conclusive statement regarding the cost-effectiveness of patient navigation programs for patients diagnosed with lung cancer can be made. Since the implementation of new healthcare models such as PN at least partially depends on their cost-effectiveness, future attempts to evaluate PN programs for lung cancer patients should consider examining outcomes related to cost-effectiveness to overcome the identified research gap.

A low cost and reliable protection scheme has been designed for a three phase induction motor against unbalance voltages, under voltage, over voltage, short circuit and overheating protection. Taking the cost factor into consideration the design has been proposed using microcontroller Atmega32, MOSFETs, relays, small CTs and PTs. However the sensitivity of the protection scheme has been not compromised. The design has been tested online in the laboratory for small motors and the same can be implemented for larger motors by replacing the i-v converters and relays of suitable ratings.

Abstract Advanced jet training still relies on old concepts and solutions that are no longer efficient when considering the current and forthcoming changes in air combat. The cost of those old solutions to develop and maintain combat pilot skills are important, adding even more constraints to the training limitations. The requirement of having a trainer aircraft able to perform also light combat aircraft operational mission is adding unnecessary complexity and cost without any real operational advantages to air combat mission training. Thanks to emerging technologies, the JANUS project will study the feasibility of a brand-new concept of agile manoeuvrable training aircraft and an integrated training system, able to provide a live, virtual and constructive environment. The JANUS concept is based on a lightweight, low-cost, high energy aircraft associated to a ground based Integrated Training System providing simulated and emulated signals, simulated and real opponents, combined with real-time feedback on pilot’s physiological characteristics: traditionally embedded sensors are replaced with emulated signals, simulated opponents are proposed to the pilot, enabling out of sight engagement. JANUS is also providing new cost effective and more realistic solutions for “Red air aircraft” missions, organised in so-called “Aggressor Squadrons”.

Background: Natural products are commonly used for treating health problems. These products may be associated with adverse events, which are defined as "noxious and unintended response to a medicinal product" by the European Medicine Agency. Objectives: To identify studies describing at least one adverse event (or with potential to promote an adverse event) related to the use of natural products, as well as to describe the involved product(s) and adverse event(s). Methods: A pre-systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Keywords: "natural product(s)" and ["adverse drug reaction(s)" or "adverse effect(s)"]. Screened databases: PubMed, SciELO, DOAJ and Google Scholar. Inclusion criteria: papers describing at least one adverse event associated with the use of natural products and published between 2017 and 2019. Exclusion criteria: Repeated studies, reviews and papers written in other languages than English, Portuguese, French or Spanish. Results: 104 studies were identified (20 PubMed; 0 SciELO; 2 DOAJ; 82 Google Scholar), but only 10 were selected (4 PubMed and 6 Google Scholar): 1 in-vitro study; 2 non-clinical studies, 1 study reporting in-vitro and clinical data and 5 studies were cases reports. Globally, 997 reports of adverse drug reactions with natural products were identified, mainly non-severe cases. Conclusion: Since a limited number of studies was found, we conclude that adverse events due to natural products may be underreported, or natural products may have a good safety profile. This review contributes for assuring the safety of natural products consumers, by evaluating the knowledge/information on the potential adverse events and interactions of these products.

Introduction Lateral condyle fractures are the second most common pediatric elbow fracture. There exist multiple options for internal fixation including buried K-wires, unburied K-wires, and screw fixation. Our study aims to review the current literature and determine if fixation strategy affects outcomes to include fracture union, postoperative range of motion, and need subsequent surgery. Methods A systematic review of Pubmed, MEDLINE, and EMBASE databases was performed. Included articles involve pediatric patients with displaced lateral condyle fractures treated with internal fixation that reported outcomes to include union rates and complications. Results Thirteen studies met inclusion criteria for a total of 1299 patients (472 buried K-wires, 717 unburied K-wires, and 110 screws). The patients’ average age was 5.8 ± 0.6 years, male (64%), and had 16.3 months of follow-up. No differences in union and infection rates were found. Unburied K-wires had the shortest time to union and the greatest elbow range of motion postoperatively. Conclusions Our systematic review demonstrates similar outcomes with union and infection rates between all fixation techniques. Unburied K-wires demonstrated a shorter time to union and the greatest postoperative range of motion. Additionally, unburied K-wires may be removed in clinic, decreasing the cost on the healthcare system. Evidence Level 3.

Introduction: The objective of this systematic review is to assess the effect of vibrational force on biomarkers for orthodontic tooth movement. Methods: An electronic search was conducted for relevant studies (up to December 31, 2020) on the following databases: Pubmed, Google scholar, Web of Science, Cochrane Library, Wiley Library, and ProQuest Dissertation Abstracts and Thesis database. Hand searching of selected orthodontic journals was also undertaken. The selected studies were assessed for the risk of bias in Cochrane collaboration risk of bias tool. The “traffic plot” and “weighted plot” risk of bias distribution are designed in the RoB 2 tool. The 2 authors extracted the data and analyzed it. Results: Six studies fulfilled the inclusion criteria. The risks of biases were high for 4, low and some concern for other 2 studies. The biomarkers, medium, device, frequency and duration of device, as well as other data were extracted. The outcomes of the studies were found to be heterogenous. Conclusion: One study showed highly statistically significant levels of IL-1 beta with <.001. Rate of tooth movement was correlated with levels of released biomarkers under the influence of vibrational force in 3 studies, but it was found to be significant only in 1 study. It was further observed that vibration does not have any significant reduction in pain and discomfort.
