As a booming system, free-floating bicycle-sharing (denoted as Mobike) attracts a large number of users due to the convenient utilization procedure. However, it brings about a rapid increase of bicycle volume on roadways, resulting in safety problems especially on road segments shared by automobiles and bikes. This study aimed to evaluate impacts of Mobike on automobile-involved bicycle crashes on shared roadways at a macro level, the network level. Relation between traffic volumes and crashes was first established...

Urban transportation systems are vulnerable to congestion, accidents, weather, special events, and other costly delays. Whereas typical policy responses prioritize reduction of delays under normal conditions to improve the efficiency of urban road systems, analytic support for investments that improve resilience (defined as system recovery from additional disruptions) is still scarce. In this effort, we represent paved roads as a transportation network by mapping intersections to nodes and road segments between the intersections to links...

Jeremy sustained bilateral complete brachial plexus injuries in an auto collision on an icy road a month before his third birthday. The accident rendered both upper extremities completely flail and insensate: he has no motor or sensory function of his shoulders, elbows, wrists, or digits. Jeremy does, however, have normal function of the lower extremities. Physical therapists have worked with the child for over a year with no noted improvement in arm function. Jeremy falls frequently, causing injury to his face and head, and occasionally, his arms get twisted or caught in his crib and his fingers turn blue...

BACKGROUND: Uveal melanoma is a rare and aggressive subtype of melanoma, with singular characteristics that separate it from the most famous cutaneous melanoma. This uncommon condition becomes even rarer if we look at young population. Common chemotherapy regimens does not work with this aggressive disease in its metastatic scenario, and the new armament like targeted and immunotherapies are still looking for more robust evidence. CASE PRESENTATION: We report a rare case of uveal melanoma in a patient younger than 20 years, with abdominal pain as his initial complaint...

Splenosis is an acquired anomaly related to heterotopic auto-transplantation of splenic tissue following abdominal trauma or splenectomy. We report the first definitive bilateral ovarian case in a 65-year-old woman who underwent splenectomy following a motor vehicle accident 44 years prior to presentation. We review the literature and discuss the main differential diagnoses. Gross examination revealed a 1-cm well-circumscribed dark nodule on the surface of each ovary. Paraffin-embedded, formalin-fixed blocks were sectioned and stained with hematoxylin-eosin and immunostains (CK5/6, Calretinin, WT1, Vimentin)...

Injuries and deaths due to road traffic crashes (RTC) are major public health concern. The Road Traffic Injury Research and Prevention Center, collects RTC data on injuries and fatalities from five emergency departments in Karachi. Data generating process (DGP) for RTC from 2007 to 2014, for monthly number of fatal and injured victims were analyzed using autoregressive integrated moving average and vector auto regression, time series models. Results provide strong evidence that the DGP for the current levels of the number of fatalities and injured owing to RTCs are significantly influenced by the own past history of the two series...

Wind erosion not only affects agricultural productivity but also soil, air, and water quality. Dust and specifically particulate matter ≤10 μm (PM-10) has adverse effects on respiratory health and also reduces visibility along roadways, resulting in auto accidents. The Wind Erosion Prediction System (WEPS) was developed by the USDA-Agricultural Research Service to simulate wind erosion and provide for conservation planning on cultivated agricultural lands. A companion product, known as the Single-Event Wind Erosion Evaluation Program (SWEEP), has also been developed which consists of the stand-alone WEPS erosion submodel combined with a graphical interface to simulate soil loss from single (i...

Fatal craniovertebral junction (CVJ) injuries were the most common cause of death in high-speed motor sports prior to 2001. Following the death of a mutual friend and race car driver, Patrick Jacquemart (1946-1981), biomechanical engineer Dr. Robert Hubbard, along with race car driver and brother-in-law Jim Downing, developed the concept for the Head and Neck Support (HANS) device to prevent flexion-distraction injuries during high-velocity impact. Biomechanical testing showed that neck shear and loading forces experienced during collisions were 3 times the required amount for a catastrophic injury...

INTRODUCTION: According to the latest version of the Abbreviated Injury Scale (AIS), all Thoraco-Lumbar Compression Fractures (TLCF) with >20% loss of height, were branded code 3 injuries, reflecting a threat for life or permanent disability. However, clinical observation suggests that that TLCF with <40% loss of height and without neurological deficits, have been noted to have a better clinical prognosis, prompting the need to segregate these injuries differently, revise the classification, and review outcomes...

RATIONALE: Fragments of glass from cars are often found at crime scenes and can be crucial evidence for solving the crime. The glass fragments are important as trace evidence at crime scenes related to car accidents and burgled homes. By identifying the origin of glass fragments, it is possible to infer the identity of a suspect. Our results represent a promising approach to a thorough forensic investigation of car glass. METHODS: Thirty-five samples from the side windows of cars produced and used in South Korea were collected from the official agencies of five car manufacturers and from two glassmakers...

Differential mobility spectrometry (DMS) is currently being used for environmental monitoring of space craft atmospheres and has been proposed for the rapid assessment of patients at accident and emergency receptions. Three studies investigated hitherto undescribed complexity in the DMS spectra of methanol, ethanol, propan-1-ol and butan-1-ol product ions formed from a (63)Ni ionisation source. 54 000 DMS spectra obtained over a concentration range of 0.01 mg m(-3)(g) to 1.80 g m(-3)(g) revealed the phenomenon of auto-modification of the product ions...

BACKGROUND: The cost of medical care is an area of major emphasis in the current healthcare environment. Medical providers have a significant role in reducing costs. One way to achieve this goal is to eliminate practices that add little value to patient care. The pelvic x-ray (PXR) obtained during the initial evaluation of blunt trauma may be an example. The objective of this study was to explore the utility of the pelvic x-ray in the initial evaluation of blunt trauma patients. METHODS: Blunt trauma patients with pelvic fractures of any type admitted to our urban trauma center from January 2012 to December 2013 were reviewed...
