IJCM_246A: Estimating the prevalence of seat belt usage in motor cars: A descriptive cross-sectional study in Mangalore

Background: Every year 1.25 million people die of road traffic accidents. Several safety measures can be taken to prevent RTAs. The SDG 2030 set the target to halve the number of global death and injuries from road traffic accidents by the year 2020. The aim of this study is to estimate the prevalence of seat belt use and factors influencing it including driver characteristics, type of car and time of day and distractions while driving. Methodology: This Descriptive cross-sectional study was set on the major roads and intersections of Mangalore, recruiting the drivers and front-seat passengers in the motor cars at the time and site of observation. Results: A total of 6165 motor cars were observed. 15 (0.2%) of these cars had completely tinted car windows, therefore out of the total, 6150 motor cars could be properly observed. 70.91% (4361) of drivers were wearing seat belts. Seat belt usage among drivers was found to be higher on highways (76.6%) as compared to on residential and city roads (69.3%). In vicinity of traffic police, 76.5% of drivers were observed to be wearing seat belts in contrary only 67.8% of them were wearing seatbelts in the absence of traffic police. Prevalence of mobile phone use and other distractions amongst drivers was 2.1%. Out of 2646 adult front seat passengers observed, only 10.9% were wearing seat belts. Conclusion: Among drivers, type of motor car, traffic zone and type of road and presence of traffic police in vicinity are significantly associated factors with seatbelt usage. Among adult front seat passengers, type of motor car, traffic zone, type of road and presence of traffic police in vicinity are significantly associated. Among front seat child passengers, type of road and traffic zone are significantly associated with seat belt usage.

Majority of them (77.7%) drive a two-wheeler. 70.3% have poor knowledge regarding airbag deployment during a crash, poor knowledge about vehicle maintenance (70.7%). About 77.7% do not use helmet, 44.9% do not use seat belt, 45.3% had distracted driving. Conclusion: The knowledge of participants was found to be fair and the practices were found to be poor.

Behaviors of pregnant women regarding travel – the case of Türkiye

Introduction and aim. With the development of transportation facilities and options, people can now travel easily. With women having a greater presence in the workforce, pregnant women can work until the eighth week before childbirth. This study was conducted to examine the behaviors of pregnant women regarding travel. Material and methods. The data for this cross-sectional and descriptive study were collected from 519 pregnant women who voluntarily participated in the research and met the research criteria. The data were analyzed using the SPSS 24 software package. Results. The average age of the participating pregnant women was 27.49±0.17, with 63.8% residing in urban areas, 74.8% be ing primiparous, and 47.6% being in the third trimester of pregnancy. A decrease in travel and car usage during pregnancy. The use of bus, train/tram/metro, taxi, bicycle/scooter, and motorcycle decreased during pregnancy, while use of car, plane, and ship/ferry increased. 81.9% of women always wore a seat belt during pregnancy. There was a statistically significant difference between the educational level of women and their car usage (p<0.005). It was found that women wore seat belts more frequently in the third trimester. As the number of pregnancies increased, the frequency of seat belt usage decreased. Conclusion. A decrease in the frequency of travel was observed among women during pregnancy. The levels of seat belt usage and correct seat belt fastening were unsatisfactory.

Covered endovascular reconstruction of the aortic bifurcation: A versatile technique with many potential applications.

We present our experience with using the bifurcated covered endovascular reconstruction technique in two unusual conditions. One patient with a traumatic "seat belt" aortic injury and a second patient with a bleeding aorto-enteric fistula were successfully treated with the CERAB technique. We discuss potential benefits of the technique outside the usual pattern of chronic atherosclerotic aortoiliac disease.

Outcome of Seatbelt Education and Safety Program Among Teenagers.

Despite the effectiveness of seatbelts, concerns persist about compliance, especially among teenagers. Survey data from a local high school and registry data from a level 1 trauma center were used to observe seatbelt and motor vehicle accident trends. The survey data was analyzed to gauge student's sentiments on seatbelt education. The trauma center data was analyzed to identify characteristics and trends among teenage motor vehicle accidents. Social media was the most common strategy selected for seatbelt safety awareness. Random seatbelt checks performed over 4 months revealed seatbelt compliance rates of 90%, 93.55%, and 96.94% after education intervention. Trauma center data showed that lack of seatbelt usage resulted in greater morbidity. These findings emphasize the need for targeted interventions. This study provides insights into creating effective education campaigns that can be used to enhance safety belt compliance and potentially reduce injury.

Carbon monoxide poisoning manifesting with rhabdomyolysis, Takotsubo syndrome, and skin lesion: A case report

Carbon monoxide (CO) poisoning is characterized by non-specific and protean clinical manifestations, exhibiting a highly variable presentation. We present a case of an 83-year-old female Alzheimer’s patient, a non-smoker, who was found unconscious in her wheelchair by her caregiver at home. The heating in the apartment was powered by liquefied petroleum gas. On admission to the emergency department, her vital signs were normal, but she was unconscious and slightly dyspneic. The examination revealed red-colored skin lesions in the submammary area, where the wheelchair safety belt was firmly fastened. The rest of the physical examination results were unremarkable. The carboxyhemoglobin level was 23%, and there was an increase in creatine phosphokinase and troponin I levels. On the 2nd day of hospitalization in the emergency ward, the electrocardiogram revealed negative T waves in the V1–V6 leads, while the bedside echocardiogram revealed apical ballooning of the left ventricle. The myocardial perfusion examination yielded a negative result for myocardial ischemia. In the management of patients with CO poisoning, it is important for emergency physicians to assess the presence of multiple organ and tissue disorders. Consequently, the patient was diagnosed with CO poisoning with skin, skeletal, and cardiac muscle involvement.

Sex-related disparities in vehicle crash injury and hemodynamics.

Multiple studies evaluate relative risk of female vs. male crash injury; clinical data may offer a more direct injury-specific evaluation of sex disparity in vehicle safety. This study sought to evaluate trauma injury patterns in a large trauma database to identify sex-related differences in crash injury victims. Data on lap and shoulder belt wearing patients age 16 and up with abdominal and pelvic injuries from 2018 to 2021 were extracted from the National Trauma Data Bank for descriptive analysis using injuries, vital signs, International Classification of Disease (ICD) coding, age, and injury severity using AIS (Abbreviated Injury Scale) and ISS (Injury Severity Score). Multiple linear regression was used to assess the relationship of shock index (SI) and ISS, sex, age, and sex*age interaction. Regression analysis was performed on multiple injury regions to assess patient characteristics related to increased shock index. Sex, age, and ISS are strongly related to shock index for most injury regions. Women had greater overall SI than men, even in less severe injuries; women had greater numbers of pelvis and liver injuries across severity categories; men had greater numbers of injury in other abdominal/pelvis injury regions. Female crash injury victims' tendency for higher (AIS) severity of pelvis and liver injuries may relate to how their bodies interact with safety equipment. Females are entering shock states (SI > 1.0) with lesser injury severity (ISS) than male crash injury victims, which may suggest that female crash patients are somehow more susceptible to compromised hemodynamics than males. These findings indicate an urgent need to conduct vehicle crash injury research within a sex-equity framework; evaluating sex-related clinical data may hold the key to reducing disparities in vehicle crash injury.

Ocular injuries associated with motor vehicle accidents: long term effects on quality of life.

To describe the prevalence and outcome of motor vehicle accidents-associated ocular injuries. A survey of patients who presented to the emergency room at a level 1 trauma center with motor vehicle accidents-associated ocular injuries. A patient questionnaire and review of clinical notes were conducted for all patients. Of 274 motor vehicle accident victims with ocular injuries who presented to the emergency room, 40 (15%) responded to the survey. Over half of them were driving a vehicle, and most reported wearing a seat belt or a helmet. Most ocular injuries were mild. The most common injuries were bone fractures, subconjunctival hemorrhage, eyelid involvement and corneal injury. Most respondents had no change in vision and perceived their ocular involvement as a minor part of their injury. Most respondents returned to work and to driving within a year. Our study sheds light on the details and extent of ocular involvement and the visual ability to perform daily activities following motor vehicle accidents.

Distinctive Pathology Associated With Focal Stenosis of the Main Pancreatic Duct Secondary to Remote Trauma: A Long-term Complication of Seat Belt Pancreatitis.

The radiologic finding of focal stenosis of the main pancreatic duct is highly suggestive of pancreatic cancer. Even in the absence of a mass lesion, focal duct stenosis can lead to surgical resection of the affected portion of the pancreas. We present four patients with distinctive pathology associated with non-neoplastic focal stenosis of the main pancreatic duct. The pathology included stenosis of the pancreatic duct accompanied by wavy, acellular, serpentine-like fibrosis, chronic inflammation with foreign body-type giant cell reaction, and calcifications. In all cases, the pancreas toward the tail of the gland had obstructive changes including acinar drop-out and interlobular and intralobular fibrosis. Three of the four patients had a remote history of major motor vehicle accidents associated with severe abdominal trauma. These results emphasize that blunt trauma can injure the pancreas and that this injury can result in long-term complications, including focal stenosis of the main pancreatic duct. Pathologists should be aware of the distinct pathology associated with remote trauma and, when the pathology is present, should elicit the appropriate clinical history.

Kinematic analysis of an unrestrained passenger in an autonomous vehicle during emergency braking.

Analyzing human body movement is a critical aspect of biomechanical studies in road safety. While most studies have traditionally focused on assessing the head-neck system due to the restraint provided by seat belts, it is essential to examine the entire pelvis-thorax-head kinematic chain when these body regions are free to move. The absence of restraint systems is prevalent in public transport and is also being considered for future integration into autonomous vehicles operating at low speeds. This article presents an experimental study examining the movement of the pelvis, thorax and head of 18 passengers seated without seat belts during emergency braking in an autonomous bus. The movement was recorded using a video analysis system capturing 100 frames per second. Reflective markers were placed on the knee, pelvis, lumbar region, thorax, neck and head, enabling precise measurement of the movement of each body segment and the joints of the lumbar and cervical spine. Various kinematic variables, including angles, displacements, angular velocities and accelerations, were measured. The results delineate distinct phases of body movement during braking and elucidate the coordination and sequentiality of pelvis, thorax and head rotation. Additionally, the study reveals correlations between pelvic rotation, lumbar flexion, and vertical trunk movement, shedding light on their potential impact on neck compression. Notably, it is observed that the elevation of the C7 vertebra is more closely linked to pelvic tilt than lumbar flexion. Furthermore, the study identifies that the maximum angular acceleration of the head and the maximum tangential force occur during the trunk's rebound against the seatback once the vehicle comes to a complete stop. However, these forces are found to be insufficient to cause neck injury. While this study serves as a preliminary investigation, its findings underscore the need to incorporate complete trunk kinematics, particularly of the pelvis, into braking and impact studies, rather than solely focusing on the head-neck system, as is common in most research endeavors.

Identifying community safety and policy-based injury prevention opportunities to reduce golf cart injuries.

In small US communities, golf cart utilization has become increasingly more common. In the past 3 years, the incidence and severity of pediatric golf cart-related trauma evaluated at our trauma center have noticeably increased. Thus, the aim of this study was to analyze trends, identify risk and protective factors, and provide community-level recommendations to improve golf cart safety for children in a coastal community. A retrospective cross-sectional study of our institutional trauma registry was performed. The registry was queried for golf cart injuries between 2012 and 2022. Demographics, accident details, hospital course, and outcomes were reviewed. Data analysis involved quantitative statistics. Incident locations were mapped, including additional data from the County emergency medical service. In addition, customer education at four prominent golf rental shops was observed. Annual golf cart-related traumas doubled starting in 2020. Of 235 total patients, 105 (46%) were children. Median age was 11.5 years (range, 2-17 years). Fifty-five percent were female, and 67% were non-Hispanic White. Eighty percent were out-of-county residents. The most common injury location was extremity (56%). The median Injury Severity Score was 4, and 3% died. Only 10% of children were restrained. Forty-one percent were ejected, and most (84%) were front-facing passengers. Ejection was associated with more severe injury (odds ratio, 4.13; p = 0.01). Most injuries occurred during 5 to 10 pm (47%), weekends, and summertime. Nighttime injuries were more severe than daytime ( p = 0.04). A hotspot of crashes was identified in a zone where golf carts were restricted. Rental stores provided education on seat belt use, car seat use for infants, and off-limit zones. However, rules were not enforced. Our results inform the following golf cart injury prevention opportunities: raising awareness of injury risks to children in high-tourist areas, partnering with rental stores to enforce rules, improving signage, adding protected lanes, and adopting a no nighttime operation policy. Prognostic and Epidemiological; Level IV.

Risk Factors for Blunt Cerebrovascular Injury in a Cohort of Pediatric Patients With Cervical Seat Belt Sign.

Blunt cerebrovascular injury (BVCI), injury to the carotid or vertebral arteries, may result from forces involving seatbelts. Although previous studies have not found a seat belt sign to be a significant predictor for BCVI, it is still used to screen patients for BCVI. This study aims to determine risk factors for BCVI within a cohort of patients with seat belt signs. We conducted a retrospective cohort study using our institutional trauma registry and included patients younger than 18 years with blunt trauma who both had a computed tomography angiography (CTA) of the neck performed and had evidence of a seat belt sign per the medical record. We reported frequencies, proportions, and measures of central tendency and conducted univariate analysis to evaluate factors associated with BCVI. We estimated the magnitude of the effect of each variable associated with the study outcome by conducting logistic regression and reporting odds ratios and 95% confidence intervals. Among all study patients, BCVI injuries were associated with Injury Severity Score higher than 15 ( P = 0.04), cervical spinal fractures ( P = 0.007), or basilar skull fractures ( P = 0.01). We observed higher proportions of children with BCVI when other motorized and other blunt mechanisms were reported as the mechanisms of injury ( P = 0.002) versus motor vehicle collision. Significant risk factors for BCVI in the presence of seat belt sign are: Injury severity score greater than 15, cervical spinal fracture, basilar skull fracture, and the other motorized mechanism of injury, similar to those in all children at risk of BCVI.

Enhancing Tractor Stability and Safety through Individual Actuators in Active Suspension

Tractor overturning accidents are a prominent safety concern in the field of agriculture. Many studies have been conducted to prevent tractor overturning accidents. Rollover protective structures and seat belts currently installed on tractors cannot prevent them from overturning. The posture of a tractor was controlled by installing individual actuators. The overturning angles of the tractor equipped with an actuator were compared with those of a tractor with no actuator. For the overturning angles in all directions of the tractor, it rotated 15° from 0° to 345°, and the actuator height suitable for the tractor posture was controlled by establishing an equation according to the tractor posture. Consequently, posture control using actuators was noticeably improved. This study proposes that tractors operating on irregular and sloping terrain be equipped with individual actuators. These results prevent tractor rollover accidents and improve safety and driving stability.

Assessing injury risks of reclined occupants in a frontal crash preceded by braking with varied seatbelt designs using the SAFER Human Body Model

Objective This study investigated the effects of different seatbelt geometries and load-limiting levels on the kinematics and injury risks of a reclined occupant during a whole-sequence frontal crash scenario, using simulations with the Active SAFER Human Body Model (Active SHBM). Methods The Active SHBM was positioned in a reclined position (50°) on a semi-rigid seat model. A whole-sequence frontal crash scenario, an 11 m/s2 Automated Emergency Braking (AEB) phase followed by a frontal crash at 50 km/h, was simulated. The seatbelt geometry was varied using either a B-pillar-integrated (BPI) or Belt-in-seat (BIS) design. The shoulder belt load-limiting level of the BPI seatbelt was also varied to achieve either similar shoulder belt forces (BPI_Lower_LL) or comparable upper body displacements (BPI_Higher_LL) to the BIS seatbelt. Kinematics of different body regions and seatbelt forces were compared. The risks of sustaining a mild traumatic brain injury (mTBI), two or more fractured ribs (NFR2+), and lumbar spine vertebral fractures were also compared. Results During the pre-crash phase, head, first thoracic vertebra, and first lumbar vertebra displacements were greater with the BPI seatbelt than with the BIS, mainly due to the lack of initial contact between the torso and the seatbelt. Pelvis pre-crash displacements, however, remained consistent across seatbelt types. In the in-crash phase, variations in shoulder belt forces were directly influenced by the different load-limiting levels of the shoulder belt. The mTBI (around 20%) and NFR2+ (around 70–100%) risks were amplified with BPI seatbelts, especially at higher load-limiting force. However, the BPI design demonstrated reduced lumbar spine fracture risks (from 30% to 1%). Conclusions The BIS seatbelt appears promising, as seen with the reduced mTBI and NFR2+ risks, for ensuring the protection of reclined occupants in frontal crashes. However, additional solutions, such as lap belt load limiting, should be considered to reduce lumbar spine loading.

Semiotic Analysis of "Hyundai Presents Re:Style 2020" Green Marketing in Automotive Ads

One detrimental consequence of the automotive industry's excessive production is the accumulation of end-of-life vehicles (ELV). ELV ought to be disposed of via a waste recycling system. As a result, the automotive sector bears a substantial obligation with regard to ELV. Hyundai is one of the automotive industries that has managed ELV effectively. The YouTube advertisement for the Hyundai Re:Style Presents 2020 model illustrates this. Hyundai's collaboration with fashion designers to recycle automobile byproducts including leather, airbags, seat belts, and glass is featured in the advertisement. They create fashion items from waste, including jewelry, denim jumpsuits, work vests, corsets, and tote bags. Researchers are intrigued by the pursuit of investigating the significance of the sign representation, the object, and the interpretant, as well as the implications of advertising within the framework of green marketing theory. To achieve this aim, the semiotic theory of Charles Sanders Peirce was employed by featuring a triadic model comprising an object, representation, and interpretant. Additionally, Sinh's green marketing framework was incorporated, comprising a green place, green product, green price, and green promotion. Consequently, A qualitative research based on Charles Sanders Peirce's semiotics was used. The results shows that the signs, objects, and interpretants in Hyundai advertisements show the meaning of green marketing.

Detection method of the seat belt for workers at height based on UAV image and YOLO algorithm

In the domain of outdoor construction within the power industry, working at significant heights is common, requiring stringent safety measures. Workers are mandated to wear hard hats and secure themselves with seat belts to prevent potential falls, ensuring their safety and reducing the risk of injuries. Detecting seat belt usage holds immense significance in safety inspections within the power industry. This study introduces detection method of the seat belt for workers at height based on UAV Image and YOLO Algorithm. The YOLOv5 approach involves integrating CSPNet into the Darknet53 backbone, incorporating the Focus layer into CSP-Darknet53, replacing the SPPF block in the SPP model, and implementing the CSPNet strategy in the PANet model. Experimental results demonstrate that the YOLOv5 algorithm achieves an elevated average accuracy of 99.2%, surpassing benchmarks set by FastRcnn, SSD, YOLOX-m, and YOLOv7. It also demonstrates superior adaptability in scenarios involving smaller objects, validated using a UAV-collected dataset of seat belt images. These findings confirm the algorithm's compliance with performance criteria for seat belt detection at power construction sites, making a significant contribution to enhancing safety measures within the power industry's construction practices.

Road traffic accidents, sanctions and delays in judgments in Court proceedings in Prizren - Republic of Kosovo

Abstract Traffic accidents are unexpected and unpleasant cases on the road, which often have consequences of damage to cars, people’s injuries and in more severe cases lead to death. These events occur for various reasons and can be the result of factors such as high speed, disregard for traffic signals, alcohol, unused safety belt, technical vehicle problems, bad weather conditions and dangerous drivers’ behavior. The consequences of traffic accidents can be very serious, including serious physical injuries, material damage to the vehicle, and in some cases loss of life. Some of the preventive measures to reduce the risk of traffic accidents include the respect for traffic rules, use of seat belts, non-consumption of alcohol at the time of driving, car maintenance, education and information. Road safety is a common challenge that requires cooperation and dedication from drivers, road authorities and the community in general. This challenge is faced by law enforcement institutions to perform the tasks and obligations deriving from the legislation in terms of discouraging legal violations by traffic participants. Therefore, this paper is intended for the discovery and interpretation of any stagnation or negligence that can lead to the encouragement of traffic participants to neglect traffic rules and laws. The analysis of this manuscript is accompanied with statistics, tables and graphs from 116 cases from a population of about 150,000 inhabitants.

Unique laparoscopic emergency management of traumatic obstructed abdominal wall hernia: A case report and review of literature

Abstract Traumatic abdominal wall hernia (TAWH) is a rare clinical occurrence, with only limited cases published since 1906. This type of hernia is primarily caused by low- or high-energy blunt force trauma, resulting in damage to abdominal wall musculature while the skin is intact. The diagnosis and management of TAWH poses a lot of challenges and complexities. Herein, we present a case of a 32-year-old male Saudi patient who sustained significant abdominal trauma as a driver involved in a front collision while wearing a seat belt. Upon arrival at the trauma center, the patient was hemodynamically stable and exhibited clinical signs of left flank bulge, seat belt sign, and abdominal bruising. First, a focused assessment with sonography for trauma (FAST) was performed, which revealed minimal free fluid in the abdomen. Subsequent contrast-enhanced IV computed tomography (CT) scan confirmed a 3.6-cm left lateral abdominal wall defect with herniation of short segments of the large and small bowel loops and adjacent subcutaneous fluid. Following initial observation, the patient developed signs of bowel obstruction. A repeat CT scan showed interval progression of the hernia, partial small bowel obstruction, and other concerning findings. An emergency laparoscopic exploration revealed a large defect at the left lumber region containing omentum and long segments of the small bowel with mild distension. The bowel and omentum were reduced. The surgical repair included herniorrhaphy and mesh placement. The patient recovered well and was discharged on the third postoperative day. This case underscores the importance of thorough evaluation and timely intervention in TAWHs. Rapid surgical management, aided by advanced imaging techniques, can lead to favorable outcomes even in complex cases involving bowel herniation and associated complications.

Design and Development of an IoT System Prototype for Safe Traffic Assurance System

In 18 months (from 2022 to the first 6 months of 2023), there were 16,229 road traffic accidents nationwide, killing 9,086 people and injuring 11,235 people. In the first 9 months of 2023 alone, there were 8,335 traffic accidents nationwide, killing 4,765 people and injuring 5,802 people. Traffic order and safety are one of the important issues related to the life and development of the country. According to statistics from the World Health Organization (WHO), each year about 1.35 million people die and 50 million people are injured due to traffic accidents. Some serious traffic accidents, killing and injuring many people, are mainly caused by high speed and violation of the regulations on alcohol concentration. Therefore, implementing safe traffic solutions to minimize loss of life and property is one of the urgent needs. The project develops an IoT system prototype that can reduce the risks of traffic accidents through a continuous monitoring of parameters during participation in traffic by vehicles. The system integrates sensors, including gas sensors (detection of alcohol concentration), vibration sensors (detection of accidents), and infrared sensors (detection of the seat belts). In case of any accident, the system can send warnings and location information to the relevant systems.
