BACKGROUND: Patients are at risk of missed or delayed injuries in the setting of multisystem trauma, which may be identified with a tertiary trauma survey (TTS). There is limited literature to support the utilization of a TTS in pediatric trauma population. We aim to assess the impact of the TTS as a quality and performance improvement tool in identifying missed or delayed injuries and improving the quality of care among pediatric trauma population. METHODS: A retrospective study assessing a quality improvement/performance improvement (QI/PI) project focusing on the administration of tertiary surveys to pediatric trauma patients was conducted at our level 1 trauma center between 08-2020 and 08-2021. Patients with injury severity scores (ISS) greater than 12 and/or an anticipated hospital stay greater than 72 hours met inclusion criteria and were included. RESULTS: Of the 535 trauma patients admitted to the pediatric trauma service during the study period, 85 (16%) patients met the criteria and received a TTS. Thirteen unaddressed or undertreated injuries were found in 11 patients: 5 cervical spine injuries, 1 subdural hemorrhage, 1 bowel injury, 1 adrenal hemorrhage, 1 kidney contusion, 2 hematomas, and 2 full thickness abrasions. Following TTS, 13 patients (15%) had additional imaging, which identified 6 of the 13 injuries. CONCLUSION: The TTS is a valuable quality and performance improvement tool in the comprehensive care of trauma patients. Standardization and implementation of a tertiary survey have the potential to facilitate the prompt detection of injuries and improve the quality of care for pediatric trauma patients. LEVEL OF EVIDENCE: III.

Background: Access to healthcare is imperative to health equity and well-being. Geographic access to healthcare can be modeled using spatial datasets on local context, together with the distribution of existing health facilities and populations. Several population datasets are currently available, but their impact on accessibility analyses is unknown. In this study, we model the geographic accessibility of public health facilities at 100-meter resolution in sub-Saharan Africa and evaluate six of the most popular gridded population datasets for their impact on coverage statistics at different administrative levels. Methods: Travel time to nearest health facilities was calculated by overlaying health facility coordinates on top of a friction raster accounting for roads, landcover, and physical barriers. We then intersected six different gridded population datasets with our travel time estimates to determine accessibility coverages within various travel time thresholds (i.e., 30, 60, 90, 120, 150, and 180-min). Results: Here we show that differences in accessibility coverage can exceed 70% at the sub-national level, based on a one-hour travel time threshold. The differences are most notable in large and sparsely populated administrative units and dramatically shape patterns of healthcare accessibility at national and sub-national levels. Conclusions: The results of this study show how valuable and critical a comparative analysis between population datasets is for the derivation of coverage statistics that inform local policies and monitor global targets. Large differences exist between the datasets and the results underscore an essential source of uncertainty in accessibility analyses that should be systematically assessed.
RESUMEN
INTRODUCTION: Mass shootings pose a considerable threat to public safety and significantly cost the United States in terms of lives and expenses. The following are the specific aims of this study: (1) to assess US mass shootings, firearm-related sales, laws, and regional differences from 2015 to 2021 and (2) to investigate changes in mass shootings and firearm sales before and during the Coronavirus Disease 2019 pandemic. METHODS: A retrospective review was conducted of mass shootings, gun sales, and laws regarding the minimum age required to purchase a firearm within the United States from 2015 to 2021. The 10 states/regions with the greatest mean mass shootings/capita from 2015 to 2021 were selected for further analysis. RESULTS: Mass shootings correlated significantly with firearm sales from 2015 to 2021 nationwide (P < 0.02 for all). The growth in mass shootings, the number killed/injured, and gun sales were greater in 2020 and 2021 compared to the years prior. The 10 states with the highest mean mass shooting/capita over the study period were Alabama, Arkansas, the District of Columbia, Illinois, Louisiana, Maryland, Mississippi, Missouri, South Carolina, and Tennessee. No significant correlation was found between the number of mass shootings/capita and the minimum age to purchase a firearm. CONCLUSIONS: Firearm sales correlated significantly with mass shootings from 2015 to 2021. Mass shootings and gun sales increased at greater rates during the Coronavirus Disease 2019 pandemic compared to the years before the pandemic. Mass shootings exhibited inconsistent trends with state gun laws regarding the minimum age to purchase a firearm. Future studies may consider investigating the methods by which firearms used in mass shootings are obtained to further identify targets for prevention.

Button battery ingestion in pediatric populations is a common occurrence with severe sequelae. Multiple case reports have established the occurrence of death, fistula formation, mucosal erosion, esophageal perforation, and bleeding post-ingestion of button batteries. However, there is a gap in the literature on the occurrence of bilateral vocal cord paralysis post-lithium battery ingestion. We present a case in which a 12-month-old male developed bilateral vocal cord paralysis following ingestion of a button battery. We compare our case to eleven other reports that exist in the literature based on age, sex, time until removal, clinical presentation, day upon which vocal cord paralysis developed, anatomic location, and post-operative course. We conclude that bilateral vocal cord paralysis is a time-sensitive complication which requires prompt diagnosis. Any child with stridor following button battery ingestion should undergo consultation with pediatric otolaryngology immediately. In addition, long-term follow-up is necessary to evaluate return of normal vocal cord function.
RESUMEN
The whole-genome sequencing analysis revealed a polyclonal dissemination of NDM-1 and NDM-9 variants in Escherichia coli (n = 20) and Klebsiella pneumoniae (n = 2) in Tahiti since 2015 via interspecies transfer of three different blaNDM-carrying plasmids (IncR, IncHI2, and IncF) and patient-to-patient cross-transmission. It highlights the potential risk of importation of NDM producers in France, where French Polynesia is not considered stricto sensu a foreign country from which repatriated patients have to be screened.

BACKGROUND: Leptospirosis is a widespread zoonosis with global impact, particularly among vulnerable populations in resource-poor settings in tropical countries. Rodents have been considered to be the main reservoir of the disease; however, a wide variety of mammals can act as hosts as well. Here we examine the genetic diversity of Leptospira strains from biological samples of patients and animals in French Polynesia (FP) from 2011 to 2019. METHODOLOGY/PRINCIPAL FINDINGS: From 2011 to 2019, we have collected 444 blood samples from patients diagnosed as having leptospirosis. The limited volume of clinical material and low amount of leptospiral DNA in blood samples led us to develop a nested PCR targeting the secY locus that enabled us to amplify and sequence 244 samples (55%). In addition, 20 Leptospira strains recovered from the blood of patients from 2002 to 2011 were sequenced and fully characterized at the serogroup level and used as reference strains for the association of different phylogenetic branches with respective serogroups. The secY sequences were compared with publicly available sequences from patients and animal reservoirs in FP (n = 79). We identified rats as the main source of infection for L. borgpetersenii serogroup Ballum and L. interrogans serogroup Icterohaemorrhagiae, dogs as the main source of infection for L. interrogans serogroup Australis, and farm pigs as the main source of infection for L. interrogans serogroups Pomona or Canicola. L. interrogans was associated with the most severe infections with 10 and 5 fatal cases due to serogroups Icterohaemorrhagiae and Australis, respectively. Mortality was significantly associated with older age (p-value < 0.001). CONCLUSIONS/SIGNIFICANCE: We described the population dynamics of leptospires circulating among patients in FP, including two patients who were reinfected with unrelated Leptospira genotypes, and clarified the local role of the animal reservoirs in the transmission route of leptospirosis to humans. Routine Leptospira genotyping directly on biological samples should allow the epidemiological follow-up of circulating strains and assess the impact of control interventions on disease transmission.

BACKGROUND: On the morning of June 12, 2016, an armed assailant entered the Pulse Nightclub in Orlando, Florida, and initiated an assault that killed 49 people and injured 53. The regional Level I trauma center and two community hospitals responded to this mass casualty incident. A detailed analysis was performed to guide hospitals who strive to prepare for future similar events. METHODS: A retrospective review of all victim charts and/or autopsy reports was performed to identify victim presentation patterns, injuries sustained, and surgical resources required. Patients were stratified into three groups: survivors who received care at the regional Level I trauma center, survivors who received care at one of two local community hospitals, and decedents. RESULTS: Of the 102 victims, 40 died at the scene and 9 died upon arrival to the Level I trauma center. The remaining 53 victims received definitive medical care and survived. Twenty-nine victims were admitted to the trauma center and five victims to a community hospital. The remaining 19 victims were treated and discharged that day. Decedents sustained significantly more bullet impacts than survivors (4 ± 3 vs. 2 ± 1; p = 0.008) and body regions injured (3 ± 1 vs. 2 ± 1; p = 0.0002). Gunshots to the head, chest, and abdominal body regions were significantly more common among decedents than survivors (p < 0.0001). Eighty-two percent of admitted patients required surgery in the first 24 hours. Essential resources in the first 24 hours included trauma surgeons, emergency room physicians, orthopedic/hand surgeons, anesthesiologists, vascular surgeons, interventional radiologists, intensivists, and hospitalists. CONCLUSION: Mass shooting events are associated with high mortality. Survivors commonly sustain multiple, life-threatening ballistic injuries requiring emergent surgery and extensive hospital resources. Given the increasing frequency of mass shootings, all hospitals must have a coordinated plan to respond to a mass casualty event. LEVEL OF EVIDENCE: Epidemiological Study, level V.

PURPOSE: Firearm injuries continue to be a common cause of injury for American children. This pilot study was developed to evaluate the feasibility of providing guidance about firearm safety to the parents of pediatric patients using a tablet-based module in the outpatient setting. METHODS: A tablet-based questionnaire that included a firearm safety message based on current best practice was administered to parents of pediatric patients at nine centers in 2018. Parents were shown a firearm safety video and then asked a series of questions related to firearm safety. RESULTS: The study was completed by 543 parents from 15 states. More than one-third (37%) of families kept guns in their home. The majority of parents (81%, nâ¯=â¯438) thought it was appropriate for physicians to provide firearm safety counseling. Two-thirds (63%) of gun owning parents who do not keep their guns locked said that the information provided in the module would change the way they stored firearms at home. CONCLUSION: Use of a tablet based firearm safety module in the outpatient setting is feasible, and the majority of parents are receptive to receiving anticipatory guidance on firearm safety. Further data is needed to evaluate whether the intervention will improve firearm safety practices in the home. LEVEL OF EVIDENCE: Level III.

BACKGROUND: In recent years, several states have enacted Stand Your Ground (SYG) legislation intended to deter crime. To date, the impact of these laws on justifiable homicide (JH) and homicide (HOM) is unknown. This study was designed to compare JH and HOM rates (JHR, HR) before and after enactment of SYG laws and in states with and without (NoSYG) such legislation. STUDY DESIGN: This was a retrospective analysis of justifiable homicide and homicide using 3 United States datasets from 2000 to 2017. Descriptive statistics and univariate linear regressions were used to evaluate the association of SYG laws and JH and HOM in the United States. RESULTS: There were 4,594 incidents of JH and 214,630 incidents of HOM in the United States between 2000 and 2017. Stand Your Ground states accounted for most JH and HOM incidents 3,184 (69%) and 116,511 (54%), respectively. Stand Your Ground states had higher JH and HOM rates than NoSYG states (0.126 vs 0.047 and 4.663 vs 3.301 per 100,000 population, respectively; p < 0.001). Comparing periods pre- (2000 to 2004) and post-SYG (2005 to 2017) law enactment, SYG vs NoSYG states had increased JH rates of 54.9% vs 20.4%, respectively (p < 0.001); HOM rates increased 10.8% in SYG states and decreased 2.3% in NoSYG states (p < 0.001). CONCLUSIONS: Stand Your Ground states had significantly higher JH and HOM rates and significantly greater increases in JH and HOM rates pre- vs post-SYG law enactment compared with NoSYG states. These results raise questions about the potential adverse consequences of policies such as the SYG law in the US.

A 59-year-old tobacco smoker male with chronic bronchitis living in Taravao, French Polynesia, Pacific, presented with a two-year growing nodule in the middle lobe of the right lung. A guided bronchoalveolar lavage inoculated onto Löwenstein-Jensen medium yielded colonies of a rapidly-growing non-chromogenic mycobacterium designed as isolate P7213. The isolate could not be identified using routine matrix-assisted laser desorption ionization-time of flight-mass spectrometry and phenotypic and probe-hybridization techniques and yielded 100% and 97% sequence similarity with the respective 16S rRNA and rpoB gene sequences of Mycobacterium virginiense in the Mycobacterium terrae complex. Electron microscopy showed a 1.15 µm long and 0.38 µm large bacillus which was in vitro susceptible to rifampicin, rifabutin, ethambutol, isoniazid, doxycycline and kanamycin. Its 4,511,948-bp draft genome exhibited a 67.6% G + C content with 4,153 coding-protein genes and 87 predicted RNA genes. Genome sequence-derived DNA-DNA hybridization, OrthoANI and pangenome analysis confirmed isolate P7213 was representative of a new species in the M. terrae complex. We named this species "Mycobacterium mephinesia".

PURPOSE: Though the total fatality and injury count in mass shootings is known, the burden on the pediatric population remains undefined. We sought to define the impact of domestic vs. public mass shootings in the pediatric population. METHODS: Open-source databases, Everytown for Gun Violence, and Mother Jones were cross-referenced and used to review domestic and public mass shootings from 2009 to 2016. Mass shootings were defined as four or more fatalities and any injuries. Domestic mass shootings were defined as ones that occurred in the home where the assailant was either a family member or a past or present intimate partner of a family member. Public mass shootings occurred in a public space where the shooter was unknown to the victim. The number of incidents in each group, fatalities and injuries, and effect on children <18â¯years were analyzed along with perpetrator characteristics. Categorical data were analyzed using Fisher's Exact test. RESULTS: There were 71 Domestic and 31 Public mass shootings accounting for 331 vs. 281 fatalities and 28 vs. 217 injuries (pâ¯<â¯0.0001). Children <18â¯years accounted for 44% of Domestic and 10% of Public fatalities (pâ¯<â¯0.0001) and 46% vs. 2% of all injuries (pâ¯<â¯0.0001). The assailant was prohibited from owning or possessing a firearm in 32% of Domestic and 39% of Public mass shootings accounting for 54 vs. 25 fatalities. CONCLUSION: The pediatric fatality rate in mass shootings is alarming, especially among Domestic shooting events. This is a public health issue and requires vigilance to protect at-risk youth. TYPE OF STUDY: Epidemiology study, retrospective review. LEVEL OF EVIDENCE: Level IV.

Human pressures on the environment are changing spatially and temporally, with profound implications for the planet's biodiversity and human economies. Here we use recently available data on infrastructure, land cover and human access into natural areas to construct a globally standardized measure of the cumulative human footprint on the terrestrial environment at 1 km(2) resolution from 1993 to 2009. We note that while the human population has increased by 23% and the world economy has grown 153%, the human footprint has increased by just 9%. Still, 75% the planet's land surface is experiencing measurable human pressures. Moreover, pressures are perversely intense, widespread and rapidly intensifying in places with high biodiversity. Encouragingly, we discover decreases in environmental pressures in the wealthiest countries and those with strong control of corruption. Clearly the human footprint on Earth is changing, yet there are still opportunities for conservation gains.

Remotely-sensed and bottom-up survey information were compiled on eight variables measuring the direct and indirect human pressures on the environment globally in 1993 and 2009. This represents not only the most current information of its type, but also the first temporally-consistent set of Human Footprint maps. Data on human pressures were acquired or developed for: 1) built environments, 2) population density, 3) electric infrastructure, 4) crop lands, 5) pasture lands, 6) roads, 7) railways, and 8) navigable waterways. Pressures were then overlaid to create the standardized Human Footprint maps for all non-Antarctic land areas. A validation analysis using scored pressures from 3114×1 km(2) random sample plots revealed strong agreement with the Human Footprint maps. We anticipate that the Human Footprint maps will find a range of uses as proxies for human disturbance of natural systems. The updated maps should provide an increased understanding of the human pressures that drive macro-ecological patterns, as well as for tracking environmental change and informing conservation science and application.
