Purpose. We evaluated the potential utility of a cost-effective 4K consumer video system for surgical education in ophthalmology. Setting. Tokai University Hachioji Hospital, Tokyo, Japan. Design. Experimental study. Methods. The eyes that underwent cataract surgery, glaucoma surgery, vitreoretinal surgery, or oculoplastic surgery between February 2016 and April 2016 were recorded with 17.2 million pixels using a high-definition digital video camera (LUMIX DMC-GH4, Panasonic, Japan) and with 0.41 million pixels using a conventional analog video camera (MKC-501, Ikegami, Japan). Motion pictures of two cases for each surgery type were evaluated and classified as having poor, normal, or excellent visibility. Results. The 4K video system was easily installed by reading the instructions without technical expertise. The details of the surgical picture in the 4K system were highly improved over those of the conventional pictures, and the visual effects for surgical education were significantly improved. Motion pictures were stored for approximately 11 h with 512 GB SD memory. The total price of this system was USD 8000, which is a very low price compared with a commercial system. Conclusion. This 4K consumer camera was able to record and play back with high-definition surgical field visibility on the 4K monitor and is a low-cost, high-performing alternative for surgical facilities.

Background: Although all microsurgeries are based on the use of surgical microscopes, several alternative magnification systems have shown promising results. Improvements in image quality facilitated the use of video systems in microsurgeries with safety and accuracy. The aim of this study was to evaluate the use of a low-cost, video-assisted magnification system in peripheral neurorrhaphy in rats. Methods: Twenty Wistar rats were randomly divided into 2 matched groups according to the magnification system used: the microscope group, with neurorrhaphy performed under a microscope with an image magnification of 40×; and the video system group, with the procedures performed under a video system composed of a high-definition Sony camcorder DCR-SR42 set to 52× magnification, macro lenses, 42-inch television, and a digital HDMI cable. We analyzed weight, nerve caliber, total surgery time, neurorrhaphy time, number of stitches, and number of axons in both ends (proximal and distal). Results: There were no significant differences between groups in weight, nerve caliber, or number of stitches. Neurorrhaphy under the video system took longer (video: 5.60 minutes; microscope: 3.20 minutes; P < .05). Number of axons was similar between groups, both in proximal and distal stumps. Conclusion: It is possible to perform a peripheral neurorrhaphy in rats through video system magnification, but with a longer surgical time.

Abstract The purpose of this study was to compare swing time and golf club angle parameters during golf swings using three, two dimensional (2D) low cost, Augmented-Video-based-Portable-Systems (AVPS) (Kinovea, SiliconCoach Pro, SiliconCoach Live). Twelve right-handed golfers performed three golf swings whilst being recorded by a high-speed 2D video camera. Footage was then analysed using AVPS-software and the results compared using both descriptive and inferential statistics. There were no significant differences for swing time and the golf phase measurements between the 2D and 3D software comparisons. In general, the results showed a high Intra class Correlation Coefficient (ICC > 0.929) and Cronbach’s Coefficient Alpha (CCA > 0.924) reliability for both the kinematic and temporal parameters. The inter-rater reliability test for the swing time and kinematic golf phase measurements on average were strong. Irrespective of the AVPS software investigated, the cost effective AVPS can produce reliable output measures that benefit golf analyses.

Abstract Aims The high cost of laparoscopic training kits is a major barrier for trainees of any level to learn basic laparoscopic skills. Research shows that consistent practice is more effective than intensive training sessions, therefore having access to an at-home training kit provides surgical trainees optimised learning opportunities. During the current pandemic when access to hospital training centres is limited, at-home training kits have become an increasingly vital component of surgical education. Methods A scoping review of current laparoscopic training kits was conducted and based on the results, medical students designed and built ultra low-cost laparoscopic graspers and training kits. Results The laparoscopic training kits were reviewed and approved by a surgical consultant and senior surgical registrars and are currently being trialled in a virtual training course at a tertiary care centre. Each kit cost £10 and was created using commonly available materials. Conclusions The ultra low-cost laparoscopic training kits were successfully created and remain one of the most cost-effective to date. These training kits provide a cost-effective solution for providing trainees with the opportunity for extended practice of basic laparoscopic skills, further improving surgical education worldwide.

Background. A literature review of the use of video systems for magnification has suggested that so far, this novel magnification system has only been used to perform arterial anastomoses. The aim of this study was to evaluate the use of 2 low-cost methods of video-assisted magnification in microvascular venous anastomosis in rats. Methods. Thirty rats were randomly divided into 3 matched groups according to the magnification system used: the microscope group, with venous anastomosis performed under a microscope; the camcorder system group, with the procedures performed under a high-definition Handycam HDR-XR160; and the Photographic camera group, for which procedures were performed with an EOS Rebel T3i photographic camera. In both video system groups, a magnification system was connected to a 42-in. television by an HDMI cable. We analyzed weight, venous caliber, total surgery and anastomosis time, patency immediately and 14 days postoperatively, number of stitches, and histological analyses. Results. There were no significant differences between the groups in weight, venous caliber, or number of stitches. Anastomosis under the video systems took longer. Patency rates were similar between the groups, except for the photographic system group that has a lower patency rate at 14 days. The histological analyses were similar in all groups. Conclusion. It is possible to perform a venous anastomosis in rats through video system magnification, with a satisfactory success rate comparable with that for procedures performed under microscopes; however, the kind of video system has a great influence on the final patency.

AbstractObjective:This study aimed to estimate the effectiveness of a full digital, high definition video system for laryngeal observations.Methods:A newly available, full digital, high definition video camera and high definition video monitor were used. With an endoscopic adaptor and rigid telescope, laryngoscopy and stroboscopy were performed on patients with various kinds of laryngeal lesions.Results:All laryngeal lesions were observed and recorded by the full digital, high definition video camera without incident. The image quality for laryngoscopy and stroboscopy was far superior to that of a conventional video system, including video-endoscopy. Even tiny structures or lesions could clearly be visualised on the monitor. The still image obtained from the full digital, high definition video camera was 1920 × 1080 pixels and was comparable to that obtained from a still camera.Conclusions:Full digital, high definition video cameras are now commonplace products and can easily be applied to patients with laryngeal disorders. They provide superior laryngeal images, compared with conventional video systems. Furthermore, high definition video systems are cheaper than proprietary medical video systems. We consider our system to represent an accessible technique of gaining superior laryngeal observation in otolaryngological clinics.

Severity Of The Disease

The major risk associated with low platelet count in pregnancy is the increased risk of bleeding during the childbirth or post that. There is an increased blood supply to the uterus during pregnancy and the surgical procedure requires cutting of major blood vessels. Women with thrombocytopenia are at increased risk of losing excessive blood. The risk is more in case of caesarean delivery as compared to vaginal delivery. Hence based on above findings the present study was planned for Assessment of the Platelet Count in the Pregnant Women in IGIMS, Patna, Bihar. The present study was planned in Department of Pathology, Indira Gandhi Institute of Medical Science, Patna, Bihar, India. The present study was planned from duration of January 2019 to June 2019. In the present study 200 pregnant females samples received for the platelet estimation were enrolled in the present study. Clinically platelet indices can be a useful screening test for early identification of preeclampsia and eclampsia. Also platelet indices can assess the prognosis of this disease in pregnant women and can be used as an effective prognostic marker because it correlates with severity of the disease. Platelet count is a simple, low cost, and rapid routine screening test. Hence the data generated from the present study concludes that platelet count can be used as a simple and cost effective tool to monitor the progression of preeclampsia, thereby preventing complications to develop during the gestational period.

The Cost

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”.

The Impact

SYNOPSIS Mandatory existence disclosure rules require an organization to disclose a policy's existence, but not its content. We examine policy adoption frequencies in the year immediately after the IRS required mandatory existence disclosure by nonprofits of various governance policies. We also examine adoption frequencies in the year of the subsequent change from mandatory existence disclosure to a disclose-and-explain regime that required supplemental disclosures about the content and implementation of conflict of interest policies. Our results suggest that in areas where there is unclear regulatory authority, mandatory existence disclosure is an effective and low cost regulatory device for encouraging the adoption of policies desired by regulators, provided those policies are cost-effective for regulated firms to implement. In addition, we find that disclose-and-explain regulatory regimes provide stronger incentives for policy adoption than do mandatory existence disclosure regimes and also discourage “check the box” behavior. Future research should examine the impact of mandatory existence disclosure rules in the year that the regulation is implemented.
