A Positioning Alarm System for Explosive Impact Debris Protective Suit Based on an Accelerometer Array.

Protection suits are vital for firefighters' safety. Traditional protection suits physically protect firemen from burns, but cannot locate the position of bodily injuries caused by impact debris. Herein, we present a wearable impact debris positioning system for firefighter protection suits based on an accelerometer array. Wearable piezoelectric accelerometers are distributed regularly on the suit to detect the vibration on different body parts, which is conducive to determining the position of injured body parts. In addition, the injured parts can be displayed on a dummy body model on the upper computer with a higher localization accuracy of 4 cm. The positioning alarm system has a rapid response time of 0.11 ms, attributed to the smart signal processing method. This work provides a reliable and smart method for locating and assessing the position of bodily injuries caused by impact debris, which is significant because it enables fire commanders to rescue injured firefighters in time.

FIRST AID EDUCATION DURING INJURY IN CHILDREN WITH RICE METHOD AT SEKOLAH INDONESIA SINGAPURA (SIS)

First Aid is an aid for emergency treatment of victims before help is provided by medical personnel. Injuries can occur anywhere, the location of injuries often occurs especially in the home and school environment. School-age children are a group that is vulnerable to injury, especially when entering celementary school. Injuries can become an emergency case and cause serious injuries and even death if not handled properly. To prevent injuries in children from getting worse, one of the methods that can be used to treat is the RICE (Rest, Ice, Compression, Elevation) method, which can first rest the injured part, apply an ice pack to reduce swelling, bandage the injured skin and elevate the injured area above the height of the heart area. First Aid community service with the RICE method at Sekolah Indonesia Singapura (SIS) is a positive activity that aims to increase children's knowledge and ability to perform first aid when injured or when children know other people are injured. The method used is counseling about first aid for injuries using the RICE method, demonstrating and distributing leaflets. The results of the analysis of children's ability to understand first aid material when injured with the RICE method before and after education is 30 (with an average pre test score of 70 and post test 100). The increase in participants' knowledge proves that with this counseling participants become more aware of what is related to first aid during injuries that can be treated with the RICE method to prevent more severe injuries.

In Situ 4D Printing of Polyelectrolyte/Magnetic Composites for Sutureless Gastric Perforation Sealing.

In situ bioprinting has emerged as one of the most promising techniques for the sutureless tissue sealing of internal organs. However, most existing in situ bioprinting methods are limited by the complex and confined printing space inside the organs, harsh curing conditions for printable bioinks, and poor ability to suturelessly seal injured parts. The combination of in situ bioprinting and 4D printing is a promising technique for tissue repair. Herein, the in situ 4D printing of polyelectrolyte/magnetic composites by gastroscopy for sutureless internal tissue sealing is reported. Using gastric perforation as an example, a gelatin/sodium alginate/magnetic bioink is developed, which can be precisely located by a gastroscope with the assistance of an external magnetic field, solidified in gastric fluid, and firmly adhered to tissue surfaces. The solidified bioink along the defect can be attracted by an external magnetic field, resulting in sutureless sealing. A demonstration using a porcine stomach with an artificial perforation confirms the feasibility of sutureless sealing using 4D printing. Moreover, an in vivo investigation on gastric perforation in a rat model identifies the biocompatibility by H&E and CD68+ staining. This study provides a new orientation and concept for functionality-modified in situ 4D bioprinting.

Simulation of neuroplasticity in a CNN-based in-silico model of neurodegeneration of the visual system.

The aim of this work was to enhance the biological feasibility of a deep convolutional neural network-based in-silico model of neurodegeneration of the visual system by equipping it with a mechanism to simulate neuroplasticity. Therefore, deep convolutional networks of multiple sizes were trained for object recognition tasks and progressively lesioned to simulate neurodegeneration of the visual cortex. More specifically, the injured parts of the network remained injured while we investigated how the added retraining steps were able to recover some of the model's object recognition baseline performance. The results showed with retraining, model object recognition abilities are subject to a smoother and more gradual decline with increasing injury levels than without retraining and, therefore, more similar to the longitudinal cognition impairments of patients diagnosed with Alzheimer's disease (AD). Moreover, with retraining, the injured model exhibits internal activation patterns similar to those of the healthy baseline model when compared to the injured model without retraining. Furthermore, we conducted this analysis on a network that had been extensively pruned, resulting in an optimized number of parameters or synapses. Our findings show that this network exhibited remarkably similar capability to recover task performance with decreasingly viable pathways through the network. In conclusion, adding a retraining step to the in-silico setup that simulates neuroplasticity improves the model's biological feasibility considerably and could prove valuable to test different rehabilitation approaches in-silico.

Cross-Limb Vascular Shunting for Traumatic Popliteal Artery Injury

Popliteal artery injury (PAI) is a challenging trauma that requires prompt and accurate treatment since the probability of lower-limb amputation increases with the ischemic time. Intravascular shunting (IVS) and cross-limb vascular shunting (CLS) are used as temporary vascular shunting (TVS) methods to shorten the ischemic time for limb vascular injury. CLS involves sending blood from an artery in a healthy body part to a peripheral vessel in an injured part to immediately resume blood flow to the injured limb. For closed injuries including PAI, CLS may be performed without exploring and identifying the arterial stumps and it enables early reperfusion to the ischemic limb. We report the cases series of traumatic PAI treated using CLS and verify the usefulness of CLS. All patients with traumatic PAI treated with CLS at our institution between August 2013 and December 2021 were included. Demographic and clinical patient characteristics were extracted from the medical records. Comorbid injuries, severity of acute limb ischemia based on Rutherford grading scale, time from injury to reperfusion by CLS, time from injury to completion of artery, and the use of fasciotomy were investigated. As outcomes, we investigated the presence or absence of lower extremity amputation during the course of treatment. We used CLS for treatment for 5 cases with traumatic PAI. Based on the Rutherford grading scale for acute limb ischemia, there were one limb with grade 2B and four with grade 3. Amputation of the lower extremities was avoided except for one extremity in which arterial reconstruction was not achieved due to unexplained cardiac arrest during surgery. CLS enables early reperfusion of the injured limb and is effective as a TVS method for traumatic PAI with severe ischemia or soft tissue damage.

The fate of mitochondria during platelet activation

AbstractBlood platelets undergo several successive motor-driven reorganizations of the cytoskeleton when they are recruited to an injured part of a vessel. These reorganizations take place during the platelet activation phase, the spreading process on the injured vessel or between fibrin fibers of the forming clot, and during clot retraction. All these steps require a lot of energy, especially the retraction of the clot when platelets develop strong forces similar to those of muscle cells. Platelets can produce energy through glycolysis and mitochondrial respiration. However, although resting platelets have only 5 to 8 individual mitochondria, they produce adenosine triphosphate predominantly via oxidative phosphorylation. Activated, spread platelets show an increase in size compared with resting platelets, and the question arises as to where the few mitochondria are located in these larger platelets. Using expansion microscopy, we show that the number of mitochondria per platelet is increased in spread platelets. Live imaging and focused ion beam–scanning electron microscopy suggest that a mitochondrial fission event takes place during platelet activation. Fission is Drp1 dependent because Drp1-deficient platelets have fused mitochondria. In nucleated cells, mitochondrial fission is associated with a shift to a glycolytic phenotype, and using clot retraction assays, we show that platelets have a more glycolytic energy production during clot retraction and that Drp1-deficient platelets show a defect in clot retraction.

Evaluation of the Relationship of Screw Pullout and Plate Fracutre in Fixation of Mandible Condyle Fractures: A Mechanistic Study.

The mandible is the most injured part of the facial skeleton, and 25-40% of mandibular fractures involve the condyle process. The aim of this study is to answer the question of the relationship between screw pullout and/or plate fracture during osteosynthesis. We tested polyurethane models of mandibles whose condylar process was cut (simulating a fracture) and fused using plates and screws. A total of 672 plates were tested. A total of 25.6% of them were fractured during the test, with most being fractures of the base of the condyle. More screws (81.97%) are pulled out from the ramus than from the condyle-69.15%. The gold standard in the osteosynthesis of condylar fractures is two straight plates. Other than these, there is no one-size-fits-all plate for every type of fracture. Plates fixed with fewer screws (smaller plates used in higher-lying fractures) are more likely to result in screw pullout. On the other hand, in plates fixed with more screws, plate fracture is more common.

Golf-related sports injuries of the musculoskeletal system.

The purpose of this study was to evaluate the characteristics of golf-related musculoskeletal injuries. Golfers were retrospectively surveyed through a 50-item questionnaire. Golfers were divided into injured and noninjured groups according to the presence or absence of musculoskeletal injuries. Of the 208 respondents, 64.0% suffered golf-related injuries, most of which were minor injuries caused by overuse in the early 9.9 weeks. According to the anatomical distribution, the most injured parts were upper limbs, spine, trunk, and lower limbs in that order. As for the distribution by part, the hand and wrist were the most vulnerable, and the lateral elbow damage was 3 times more common than the inner elbow. Self-management for injuries was the most common treatment, and regular preventive exercise accounted for 30% of the injured. Overall, more than half of the respondents suffered from musculoskeletal injuries, self-management was the most common, and less than one-third did regular exercise to prevent injuries. Therefore, active management to prevent golf-related musculoskeletal injuries may be necessary.

Receptivity of injured and aged coconut petiole for oviposition by red palm weevil Rhynchophorus ferrugineus (Coleoptera: Curculionidae)

Red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae) is a key pest of palm-based ecosystem. Globally R. ferrugineus is reported from 50 countries infecting 40 palm species. R. ferrugineus are attracted to wounded, damaged, dying palms or apparently healthy palms. R. ferrugineus gains entry into a palm when female weevils are drawn to palm tissue volatiles to lay eggs. The females use the rostrum to bore into palm tissue to form a hole for oviposition. Because of its cryptic feeding habit management of R. ferrugineus is difficult leading to death of palms. The laboratory study was conducted with the aim to assess the ovipositional preference of injured and aged coconut petiole (var. Benaulim) to red palm weevil R. ferrugineus (Coleoptera: Curculionidae). Results reveals that freshly injured coconut petiole was most preferred for egg laying by R. ferrugineus (mean egg lay: 4.11) and was statistically at par with one and two-day old, injured coconut petiole, indicating that injuries and wounds on coconut petiole between 0-2 days after damage emit palm volatiles that are most attractive to female R. ferrugineus adults for egg laying. It concludes that injured part should be treated with effective insecticides immediately after damage to prevent further losses.

FREQUENCY OF INJURIES IN BASKETBALL - A SYSTEMATIC REVIEW

Basketball is a team sport that is really demanding due to its dynamism and variety of motor, technical and tactical abilities that are necessary for the successful performance of basketball elements. The following databases were used to collect adequate literature: GoogleScholar, PubMed. For the analysis, studies were taken that investigated the frequency of injuries in professional, semi-professional and elite basketball players. In order for the studies to meet the inclusion criteria, they contained complete data on the type of injury, localization, and frequency of injury on the tested sample. The total number of respondents in all surveys was 3,802 respondents from all collected and analyzed previous surveys. In this study, more than 4,260 basketball injuries from 15 analyzed studies were analyzed, and after analyzing the results of these studies, it was noted that the most injuries were in the lower extremities in the amount of (66.6%), and the number of injuries in the ankle joint was (33.6% ), while the second most injured part of the body was the knee (19.4%). As for upper extremity injuries, hand, finger and wrist injuries predominate (7.1%) compared to shoulder, hand and forearm injuries (5.8%). This study found that jumping/landing, turning or stopping, or contact with an opponent are the most common causes of injury in basketball players. It can be said that a large number of injuries can occur due to the increased fatigue of basketball players, so it can also be said that a proper training program can be the best prevention of injuries in basketball players. It is concluded that basketball is a sport with a high frequency of injuries.

Emergency Department Pediatric Readiness Among US Trauma Centers: A Machine Learning Analysis of Components Associated With Survival.

We used machine learning to identify the highest impact components of emergency department (ED) pediatric readiness for predicting in-hospital survival among children cared for in US trauma centers. ED pediatric readiness is associated with improved short-term and long-term survival among injured children and part of the national verification criteria for US trauma centers. However, the components of ED pediatric readiness most predictive of survival are unknown. This was a retrospective cohort study of injured children below 18 years treated in 458 trauma centers from January 1, 2012, through December 31, 2017, matched to the 2013 National ED Pediatric Readiness Assessment and the American Hospital Association survey. We used machine learning to analyze 265 potential predictors of survival, including 152 ED readiness variables, 29 patient variables, and 84 ED-level and hospital-level variables. The primary outcome was in-hospital survival. There were 274,756 injured children, including 4585 (1.7%) who died. Nine ED pediatric readiness components were associated with the greatest increase in survival: policy for mental health care (+8.8% change in survival), policy for patient assessment (+7.5%), specific respiratory equipment (+7.2%), policy for reduced-dose radiation imaging (+7.0%), physician competency evaluations (+4.9%), recording weight in kilograms (+3.2%), life support courses for nursing (+1.0%-2.5%), and policy on pediatric triage (+2.5%). There was a 268% improvement in survival when the 5 highest impact components were present. ED pediatric readiness components related to specific policies, personnel, and equipment were the strongest predictors of pediatric survival and worked synergistically when combined.

A Study on the Structure and Biomedical Application Characteristics of Phosphate Coatings on ZKX500 Magnesium Alloys.

Magnesium-matrix implants can be detected by X-ray, making post-operative monitoring easier. Since the density and mechanical properties of Mg alloys are similar to those of human bones, the stress-shielding effect can be avoided, accelerating the recovery and regeneration of bone tissues. Additionally, Mg biodegradability shields patients from the infection risk and medical financial burden of needing another surgery. However, the major challenge for magnesium-matrix implants is the rapid degradation rate, which necessitates surface treatment. In this study, the ZKX500 Mg alloy was used, and a non-toxic and eco-friendly anodic oxidation method was adopted to improve corrosion resistance. The results indicate that the anodic coating mainly consisted of magnesium phosphate. After anodic oxidation, the specimen surface developed a coating and an ion-exchanged layer that could slow down the degradation and help maintain the mechanical properties. The results of the tensile and impact tests reveal that after being immersed in SBF for 28 days, the anodic oxidation-treated specimens maintained good strength, ductility, and toughness. Anodic coating provides an excellent surface for cell attachment and growth. In the animal experiment, the anodic oxidation-treated magnesium bone screw used had no adverse effect and could support the injured part for at least 3 months.

Correlation analysis of national elite Chinese male table tennis players' shoulder proprioception and muscle strength.

BACKGROUNDShoulder is the most injured part in table tennis players, and it takes multiple roles in transmitting power and striking the center of the ball during the stroke. Proprioception is strongly correlated with high level of athletic performance. It is customary to assume that there is a correlation between proprioception and muscle strength and therefore proprioceptive assessment and rehabilitation is often neglected.AIMTo investigate the correlation between isokinetic muscle strength and proprioception in the internal and external rotation muscle groups of elite Chinese male table tennis players, to provide reference for physical training and rehabilitation of elite table tennis players.METHODSA total of 19 national elite table tennis players from the Chinese National Table Tennis Team were recruited in this research. All of them had more than 10 years training experience and had participated major competitions such as the National Games and World Youth Championships. IsoMed 2000 was used to test the peak torque of internal and external rotation isokinetic concentric contraction of the athletes' bilateral shoulder joints at low speed (60°/s) and high speed (180°/s) respectively; IsoMed 2000 was used to conduct the Joint Position Reproduction test to evaluate the athletes' proprioceptive ability capacity at low speed (60°/s) and high speed (180°/s) respectively. If the data satisfied the normal distribution, the correlation between the differences in peak torque s and angles in different directions was analyzed using a Pearson simple linear model; otherwise, Spearman correlation analysis was used. The comparison of proprioceptive ability between the table tennis racket-holding hand and non-racket-holding hands was performed using independent samples t-test if the data satisfied a normal distribution; otherwise, the Mann-Whitney U test was used.RESULTSThere was no direct linear correlation between the strength and proprioceptive correlation analysis at slow speed (60°/s) and fast speed (180°/s) in the racket-holding hand; At the slow speed (60°/s) and fast speed (180°/s), there was no correlation between muscle strength and proprioception in the non-racket-holding hand except for the internal rotation variable error (VE) and external rotation relative peak torque, which showed a moderate positive correlation (r = 0.477, P < 0.05), (r = 0.554, P < 0.05). The internal rotation’s constant error (CE) and VE were 1.06 ± 3.99 and 2.94 ± 2.16, respectively, for the racket-holding hand, and -3.36 ± 2.39 and 1.22 ± 0.93, respectively, for the non-racket-holding hand; the internal rotation’s CE, VE of the racket-holding hand was lower than that of the non-racket-holding hand, and there was a highly significant difference (P < 0.01).CONCLUSIONThere was no correlation between muscle strength and proprioceptive function in the internal and external rotation of the racket-holding hand’s shoulder in elite Chinese male table tennis players. These results may be useful for interventions for shoulder injuries and for the inclusion of proprioceptive training in rehabilitation programs.

One DOF passive Glove for Thumb rehabilitation

Nowadays, with increasing the injuries to the hand, specially fingers, because of saving in time and money, wearable robots are so practical to use in order to rehabilitate the injured part of the body. This exoskeleton is designed to rehabilitate the thumb to do the opposition movement, which is one DOF (degree of freedom) and a passive type with the cable mechanism. These cables are placed by two drums, one on the thumb and the other on the tip of the assistive finger, and have a cable adjusting screw that can be adjusted for fingers of different lengths. To choose the assistive finger from 4 intact fingers, the two perspectives of the cable length changes and finger forces are compared. Finally, with the help of these comparisons, the middle finger was selected as the assistive finger. Furthermore, by safety factor of 36.78, the cable traction forces do not harm the fingers' joins. The most angle difference between thumb and middle is at the 140 degrees angle, at the third joint, the performance of the thumb is better, due to the least angle difference.

Review article on criteria for selection of patient for periodontal splinting

A ‘splint’ is a device for supporting weakened tissues. Periodontal splints have been defined in a variety of styles. It is defined as a rigid or flexible device that maintains in position a displaced or movable part; also used to keep in place and protect an injured part. A splint does not make loose teeth tight. Only the removal of disease and subsequent healing can achieve a real reduction in tooth mobility. This review article is on Criteria for selection of Patient for Periodontal Splinting.

A Data Augmentation Method for War Trauma Using the War Trauma Severity Score and Deep Neural Networks

The demand for large-scale analysis and research of data on trauma from modern warfare is increasing day by day, but the amount of existing data is not sufficient to meet such demand. In this study, an integrated modeling approach incorporating a war trauma severity scoring algorithm (WTSS) and deep neural networks (DNN) is proposed. First, the proposed WTSS, which uses multiple non-linear regression based on the characteristics of war trauma data and the medical evaluation by an expert panel, performed a standardized assessment of an injury and predicts its trauma consequences. Second, to generate virtual injury, based on the probability of occurrence, the injured parts, injury types, and complications were randomly sampled and combined, and then WTSS was used to assess the consequences of the virtual injury. Third, to evaluate the accuracy of the predicted injury consequences, we built a DNN classifier and then trained it with the generated data and tested it with real data. Finally, we used the Delphi method to filter out unreasonable injuries and improve data rationality. The experimental results verified that the proposed approach surpassed the traditional artificial generation methods, achieved a prediction accuracy of 84.43%, and realized large-scale and credible war trauma data augmentation.

Recent advancement in the method of transdermal drug delivery system: A review

A transdermal patch is a medicated adhesive patch that is applied to the skin and used to deliver a particular amount of medication into the bloodstream through the skin. It aids in the recovery of an injured bodily part. The transdermal drug delivery system (TDDS) provides an alternative safe means of drug delivery to previous intrusive techniques. In the past, topically applied lotions and ointments were the most commonly utilised systems for dermatological issues. The fact that some of these formulations cause systemic side effects indicates that they are absorbed through the skin. All topically applied medication formulations intended to transport the active ingredient into the general circulation are included in the transdermal delivery system. To overcome the skin's formidable barrier to topical medication administration, several substances have been utilised. Because of their unique qualities, such as improved bioavailability, regulated pharmaceutical release, and improved patient compliance, TDDS have recently gained increased attention. The current review focuses on the various advancements in transdermal drug delivery, as well as the various available methods for preparing transdermal patches, characterization and assessment tools for transdermal patch preparation, patents, transdermal compound clinical trials, and drug approved and future applications of transdermal drug delivery systems. As a result, in recent years, the Transdermal Drug Delivery System has received a lot of attention.
