Abstract
People suffering from critical injuries/illness face marked challenges before transportation to definitive care. Solutions to diagnose and intervene in the prehospital setting are required to improve outcomes. Despite advances in artificial intelligence and robotics, near-term practical interventions for catastrophic injuries/illness will require humans to perform unfamiliar, uncomfortable and risky interventions. Development of posttraumatic stress disorder is already disproportionately high among first responders and correlates with uncertainty and doubts concerning decisions, actions and inactions. Technologies such as remote telementoring (RTM) may enable such interventions and will hopefully decrease potential stress for first responders. How thought processes may be remotely assisted using RTM and other technologies should be studied urgently. We need to understand if the use of cognitively offloading technologies such as RTM will alleviate, or at least not exacerbate, the psychological stresses currently disabling first responders.

Abstract
BACKGROUND Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. A further therapeutic option may be open abdomen (OA) management with negative peritoneal pressure therapy (NPPT) to remove inflammatory ascites and attenuate the systemic damage from SCIAS, although there are definite risks of leaving the abdomen open whenever it might possibly be closed. This potential therapeutic paradigm is the rationale being assessed in the Closed Or Open after Laparotomy (COOL trial) ( https://clinicaltrials.gov/ct2/show/NCT03163095 ). Initially, the COOL trial received Industry sponsorship; however, this funding mandated the use of a specific trademarked and expensive NPPT device in half of the patients allocated to the intervention (open) arm. In August 2022, the 3 M/Acelity Corporation without consultation but within the terms of the contract canceled the financial support of the trial. Although creating financial difficulty, there is now no restriction on specific NPPT devices and removing a cost-prohibitive intervention creates an opportunity to expand the COOL trial to a truly global basis. This document describes the evolution of the COOL trial, with a focus on future opportunities for global growth of the study. METHODS The COOL trial is the largest prospective randomized controlled trial examining the random allocation of SCIAS patients intra-operatively to either formal closure of the fascia or the use of the OA with an application of an NPPT dressing. Patients are eligible if they have free uncontained intraperitoneal contamination and physiologic derangements exemplified by septic shock OR severely adverse predicted clinical outcomes. The primary outcome is intended to definitively inform global practice by conclusively evaluating 90-day survival. Initial recruitment has been lower than hoped but satisfactory, and the COOL steering committee and trial investigators intend with increased global support to continue enrollment until recruitment ensures a definitive answer. DISCUSSION OA is mandated in many cases of SCIAS such as the risk of abdominal compartment syndrome associated with closure, or a planned second look as for example part of "damage control"; however, improved source control (locally and systemically) is the most uncertain indication for an OA. The COOL trial seeks to expand potential sites and proceed with the evaluation of NPPT agnostic to device, to properly examine the hypothesis that this treatment attenuates systemic damage and improves survival. This approach will not affect internal validity and should improve the external validity of any observed results of the intervention. TRIAL REGISTRATION National Institutes of Health ( https://clinicaltrials.gov/ct2/show/NCT03163095 ).

Abstract
Introduction Remotely Piloted Aircraft Systems (RPAS) can access patients inaccessible to traditional rescue. Just-in-time remote telementoring (RTM) of naïve users to self-care could potentially address challenges in salvaging exsanguination in remote environments. Methods An exsanguination self-application task was established in a wilderness location. Three volunteers-initiated distress calls to prompt RPAS precision delivered STOP-THE-BLEED kits, after which a remote mentor directed the volunteers how to self-care. Results Limited connectivity prevented video, however each volunteer delivered images and initiated conversation with the mentor pre-RPAS arrival. Thereafter, all subjects were able to unpack and deploy hemorrhage control adjuncts under verbal direction, and to simulate self-application. All subjects were able to successfully apply wound-clamps, tourniquets, and pack wounds although one had insufficient pressure. Discussion RPASs can deliver supplies long before human rescuers, and communication connectivity might allow remote mentoring in device application. Further development of technology and self-care paradigms for exsanguination are encouraged.

Abstract
Point-of-Care ultrasound (POCUS) is an invaluable tool permitting the understanding of critical physiologic and anatomic details wherever and whenever a patient has a medical need. Thus the application of POCUS has dramatically expanded beyond hospitals to become a portable user-friendly technology in a variety of prehospital settings. Traditional thinking holds that a trained user is required to obtain images, greatly handicapping the scale of potential improvements in individual health assessments. However, as the interpretation of ultrasound images can be accomplished remotely by experts, the paradigm wherein experts guide novices to obtain meaningful images that facilitate remote care is being embraced worldwide. The ultimate extension of this concept is for experts to guide patients to image themselves, enabling secondary disease prevention, home-focused care, and self-empowerment of the individual to manage their own health. This paradigm of remotely telementored self-performed ultrasound (RTMSPUS) was first described for supporting health care on the International Space Station. The TeleMentored Ultrasound Supported Medical Interventions (TMUSMI) Research Group has been investigating the utility of this paradigm for terrestrial use. The technique has particular attractiveness in enabling surveillance of lung health during pandemic scenarios. However, the paradigm has tremendous potential to empower and support nearly any medical question poised in a conscious individual with internet connectivity able to follow the directions of a remote expert. Further studies and development are recommended in all areas of acute and chronic health care.

Abstract
BACKGROUND Early hemorrhage control after interpersonal violence is the most urgent requirement to preserve life and is now recognized as a responsibility of law enforcement. Although earlier entry of first responders is advocated, many shooting scenes remain unsafe for humans, necessitating first responses conducted by robots. Thus, robotic hemorrhage control warrants study as a care-under-fire treatment option. METHODS Two bomb disposal robots (Wolverine and Dragon Runner) were retrofitted with hemostatic wound clamps. The robots' ability to apply a wound clamp to a simulated extremity exsanguination while controlled by 4 experienced operators was tested. The operators were randomly assigned to perform 10 trials using 1 robot each. A third surveillance robot (Stair Climber) provided further visualization for the operators. We assessed the success rate of the application of the wound clamp to the simulated wound, the time to application of the wound clamp and the amount of fluid loss. We also assessed the operators' efforts to apply the wound clamp after an initial attempt was unsuccessful or after the wound clamp was dropped. RESULTS Remote robotic application of a wound clamp was demonstrated to be feasible, with complete cessation of simulated bleeding in 60% of applications. This finding was consistent across all operators and both robots. There was no difference in the success rates with the 2 robots (p = 1.00). However, there were differences in fluid loss (p = 0.004) and application time (p < 0.001), with the larger (Wolverine) robot being faster and losing less fluid. CONCLUSION Law enforcement tactical robots were consistently able to provide partial to complete hemorrhage control in a simulated extremity exsanguination. Consideration should be given to using this approach in care-under-fire and care-behind-the-barricade scenarios as well as further developing the technology and doctrine for robotic hemorrhage control.

Abstract
Background SARS-CoV-2 infection, manifesting as COVID-19 pneumonia, constitutes
a global pandemic that is disrupting health-care systems. Most patients who are
infected are asymptomatic/pauci-symptomatic can safely self-isolate at home.
However, even previously healthy individuals can deteriorate rapidly with
life-threatening respiratory failure characterized by disproportionate hypoxemic
failure compared to symptoms. Ultrasound findings have been proposed as an early
indicator of progression to severe disease. Furthermore, ultrasound is a safe
imaging modality that can be performed by novice users remotely guided by experts.
We thus examined the feasibility of utilizing common household
informatic-technologies to facilitate self-performed lung ultrasound. Methods A lung ultrasound expert remotely mentored and guided participants
to image their own chests with a hand-held ultrasound transducer. The results were
evaluated in real time by the mentor, and independently scored by three
independent experts [planned a priori]. The primary outcomes were feasibility in
obtaining good-quality interpretable images from each anatomic location
recommended for COVID-19 diagnosis. Results Twenty-seven adults volunteered. All could be guided to obtain
images of the pleura of the 8 anterior and lateral lung zones (216/216 attempts).
These images were rated as interpretable by the 3 experts in 99.8% (647/648) of
reviews. Fully imaging one’s posterior region was harder; only 108/162 (66%) of
image acquisitions was possible. Of these, 99.3% of images were interpretable in
blinded evaluations. However, 52/54 (96%) of participants could image their lower
posterior lung bases, where COVID-19 is most common, with 99.3% rated as
interpretable. Conclusions Ultrasound-novice adults at risk for COVID-19 deterioration can be
successfully mentored using freely available software and low-cost ultrasound
devices to provide meaningful lung ultrasound surveillance of themselves that
could potentially stratify asymptomatic/paucisymptomatic patients with early risk
factors for serious disease. Further studies examining practical logistics should
be conducted. Trial Registration: ID

Abstract
Traumatic pneumothoraces remain a life-threatening problem that may be resolved quickly with timely diagnosis. Unfortunately, they are still not optimally managed. The most critically injured patients with hemodynamic instability require immediate diagnoses of potentially correctible conditions in the primary survey. Point-of-care ultrasonography (POCUS) performed by the responsible physician can be a tremendous adjunct to expediting diagnoses in the primary surgery and can typically be done in seconds rather than minutes. If more detailed sonographic examination is required, the secondary survey of the hemodynamically unstable patient is more appropriate. All involved in bedside care need to be conscious to efficiently integrate POCUS into resuscitation with the right intentions and goals to avoid sono-paralysis of the resuscitation sequence. Sono-paralysis has recently been described as critical situations wherein action is delayed through unnecessary imaging after a critical diagnosis has been made or unnecessary imaging details are sought despite an urgent diagnosis being made.

Abstract
COVID-19 has impacted human life globally and threatens to overwhelm health-care resources. Infection rates are rapidly rising almost everywhere, and new approaches are required to both prevent transmission, but to also monitor and rescue infected and at-risk patients from severe complications. Point-of-care lung ultrasound has received intense attention as a cost-effective technology that can aid early diagnosis, triage, and longitudinal follow-up of lung health. Detecting pleural abnormalities in previously healthy lungs reveal the beginning of lung inflammation eventually requiring mechanical ventilation with sensitivities superior to chest radiographs or oxygen saturation monitoring. Using a paradigm first developed for space-medicine known as Remotely Telementored Self-Performed Ultrasound (RTSPUS), motivated patients with portable smartphone support ultrasound probes can be guided completely remotely by a remote lung imaging expert to longitudinally follow the health of their own lungs. Ultrasound probes can be couriered or even delivered by drone and can be easily sterilized or dedicated to one or a commonly exposed cohort of individuals. Using medical outreach supported by remote vital signs monitoring and lung ultrasound health surveillance would allow clinicians to follow and virtually lay hands upon many at-risk paucisymptomatic patients. Our initial experiences with such patients are presented, and we believe present a paradigm for an evolution in rich home-monitoring of the many patients expected to become infected and who threaten to overwhelm resources if they must all be assessed in person by at-risk care providers.

Abstract
OBJECTIVE As the incidence of active shooters increase, local emergency response has also changed. South Metro Fire Rescue coordinated a series of hyper-realistic active shooter simulation drills involving multiple agencies. METHODS "The Next Nine Minutes" was one of the largest active shooter drills performed to date with 904 personnel that were trained in 18 mass casualty active shooter drills. Evaluation was from point of injury to and including care in the operating room (OR), and evaluation of real-time system logistics. RESULTS A total of 126 patients in Cut Suits® received a total of 479 procedures such as needle decompressions, cricothyrotomies, tourniquets, wound packs, and chest tubes. Central to this exercise, law enforcement (LE) established a warm zone from the initial shooting. EMS was able to move into the facility, locate casualties, extract the first victim, move them to a casualty collection point (CCP), and transport them to safety within 12 minutes. CONCLUSIONS Strengths and weaknesses were identified in prehospital and in-hospital care. These included what roles agencies play in a true event, specific timing in establishing areas such as the warm zone and CCP, transportation, and logistics at the accepting hospitals. Only after the barriers to success were identified and addressed did the timing of casualty movement drastically improve. Lessons learned from this training were ultimately used to save lives at the STEM School, Highlands Ranch, and Colorado Shooting. This in situ immersion training should be practiced as a whole system.

Abstract
Humans are destined to explore space, yet critical illness and injury may be catastrophically limiting for extraterrestrial travel. Humans are superorganisms living in symbiosis with their microbiomes, whose genetic diversity dwarfs that of humans. Symbiosis is critical and imbalances are associated with disease, occurring within hours of serious illness and injury. There are many characteristics of space flight that negatively influence the microbiome, especially deep space itself, with its increased radiation and absence of gravity. Prolonged weightlessness causes many physiologic changes that are detrimental; some resemble aging and will adversely affect the ability to tolerate critical illness or injury and subsequent treatment. Critical illness-induced intra-abdominal hypertension (IAH) may induce malperfusion of both the viscera and microbiome, with potentially catastrophic effects. Evidence from animal models confirms profound IAH effects on the gut, namely ischemia and disruption of barrier function, mechanistically linking IAH to resultant organ dysfunction. Therefore, a pathologic dysbiome, space-induced immune dysfunction and a diminished cardiorespiratory reserve with exacerbated susceptibility to IAH, imply that a space-deconditioned astronaut will be vulnerable to IAH-induced gut malperfusion. This sets the stage for severe gut ischemia and massive biomediator generation in an astronaut with reduced cardiorespiratory/immunological capacity. Fortunately, experiments in weightless analogue environments suggest that IAH may be ameliorated by conformational abdominal wall changes and a resetting of thoracoabdominal mechanics. Thus, review of the interactions of physiologic changes with prolonged weightlessness and IAH is required to identify appropriate questions for planning exploration class space surgical care.

Abstract
Humans are destined to explore space, yet critical illness and injury may be catastrophically limiting for extraterrestrial travel. Humans are superorganisms living in symbiosis with their microbiomes, whose genetic diversity dwarfs that of humans. Symbiosis is critical and imbalances are associated with disease, occurring within hours of serious illness and injury. There are many characteristics of space flight that negatively influence the microbiome, especially deep space itself, with its increased radiation and absence of gravity. Prolonged weightlessness causes many physiologic changes that are detrimental; some resemble aging and will adversely affect the ability to tolerate critical illness or injury and subsequent treatment. Critical illness-induced intra-abdominal hypertension (IAH) may induce malperfusion of both the viscera and microbiome, with potentially catastrophic effects. Evidence from animal models confirms profound IAH effects on the gut, namely ischemia and disruption of barrier function, mechanistically linking IAH to resultant organ dysfunction. Therefore, a pathologic dysbiome, space-induced immune dysfunction and a diminished cardiorespiratory reserve with exacerbated susceptibility to IAH, imply that a space-deconditioned astronaut will be vulnerable to IAH-induced gut malperfusion. This sets the stage for severe gut ischemia and massive biomediator generation in an astronaut with reduced cardiorespiratory/immunological capacity. Fortunately, experiments in weightless analogue environments suggest that IAH may be ameliorated by conformational abdominal wall changes and a resetting of thoracoabdominal mechanics. Thus, review of the interactions of physiologic changes with prolonged weightlessness and IAH is required to identify appropriate questions for planning exploration class space surgical care.

Abstract
Purpose: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is an acute respiratory illness. Although most infected persons are asymptomatic or have only mild symptoms, some patients progress to devastating disease; such progression is difficult to predict or identify in a timely manner. COVID-19 patients who do not require hospitalization can self-isolate at home. Calls from one disease epicenter identify the need for homebased isolation with telemedicine surveillance to monitor for impending deterioration. Methodology: Although the dominant approach for these asymptomatic/paucisymptomatic patients is to monitor oxygen saturation, we suggest additionally considering the potential merits and utility of home-based imaging. Chest computed tomography is clearly impractical, but ultrasound has shown comparable sensitivity for lung involvement, with major advantages of short and simple procedures, low cost, and excellent repeatability. Thoracic ultrasound may thus allow remotely identifying the development of pneumonitis at an early stage of illness and potentially averting the risk of insidious deterioration to severe pneumonia and critical illness while in home isolation. Conclusions: Lung sonography can be easily performed by motivated nonmedical caregivers when directed and supervised in real time by experts. Remote mentors could thus efficiently monitor, counsel, and triage multiple home-based patients from their "control center." Authors believe that this approach deserves further attention and study to reduce delays and failures in timely hospitalization of home-isolated patients.

Abstract
Summary Providing the earliest hemorrhage control is now recognized as a shared responsibility of all members of society, including both the lay public and professionals, consistent with the Stop the Bleed campaign. However, providing early hemorrhage control in a hostile environment, such as the scene of a mass shooting, is extremely challenging. In such settings, the first access to a bleeding victim may be robotic. An all-purpose bomb robot was thus retrofitted with a commercial, off-the-shelf wound clamp and successfully applied to an extremity exsanguination simulator as a demonstration of remote robotic hemorrhage control. As this method can potentially control extremity hemorrhage, further development of the techniques, equipment and, most importantly, the guidelines and rules of engagement should continue. We suggest that in order to minimize the loss of life during an active shooter incident, the armamentarium of prehospital medical resources may be extended to include law-enforcement robots.

Abstract
Background Severe complicated intra-abdominal sepsis (SCIAS) has high mortality, thought due in part to progressive bio-mediator generation, systemic inflammation, and multiple organ failure. Treatment includes early antibiotics and operative source control. At surgery, open abdomen management with negative-peritoneal-pressure therapy (NPPT) has been hypothesized to mitigate MOF and death, although clinical equipoise for this operative approach exists. The Closed or Open after Laparotomy (COOL) study (https://clinicaltrials.gov/ct2/show/NCT03163095) will prospectively randomize eligible patients intra-operatively to formal abdominal closure or OA with NPTT. We review the ethical basis for conducting research in SCIAS. Main body Research in critically ill incapacitated patients is important to advance care. Conducting research among SCIAS is complicated due to the severity of illness including delirium, need for emergent interventions, diagnostic criteria confirmed only at laparotomy, and obtundation from anaesthesia. In other circumstances involving critically ill patients, clinical experts have worked closely with ethicists to apply principles that balance the rights of patients whilst simultaneously permitting inclusion in research. In Canada, the Tri-Council Policy Statement-2 (TCPS-2) describes six criteria that permit study enrollment and randomization in such situations: (a) serious threat to the prospective participant requires immediate intervention; (b) either no standard efficacious care exists or the research offers realistic possibility of direct benefit; (c) risks are not greater than that involved in standard care or are clearly justified by prospect for direct benefits; (d) prospective participant is unconscious or lacks capacity to understand the complexities of the research; (e) third-party authorization cannot be secured in sufficient time; and (f) no relevant prior directives are known to exist that preclude participation. TCPS-2 criteria are in principle not dissimilar to other (inter)national criteria. The COOL study will use waiver of consent to initiate enrollment and randomization, followed by surrogate or proxy consent, and finally delayed informed consent in subjects that survive and regain capacity. Conclusions A delayed consent mechanism is a practical and ethical solution to challenges in research in SCIAS. The ultimate goal of consent is to balance respect for patient participants and to permit participation in new trials with a reasonable opportunity for improved outcome and minimal risk of harm.

Abstract
Background: Most deaths in military trauma occur soon after wounding, and demand immediate on scene interventions. Although hemorrhage predominates as the cause of potentially preventable death, airway obstruction and tension pneumothorax are also frequent. First responders caring for casualties in operational settings often have limited clinical experience. Introduction: We hypothesized that communications technologies allowing for real-time communications with a senior medically experienced provider might assist in the efficacy of first responding to catastrophic trauma. Methods: Thirty-three basic life saving (BLS) medics were randomized into two groups: either receiving telementoring support (TMS, n = 17) or no telementoring support (NTMS, n = 16) during the diagnosis and resuscitation of a simulated critical battlefield casualty. In addition to basic life support, all medics were required to perform a procedure needle thoracentesis (not performed by BLS medics in Israel) for the first time. TMS was performed by physicians through an internet link. Performance was assessed during the simulation and later on review of videos. Results: The TMS group was significantly more successful in diagnosing (82.35% vs. 56.25%, p = 0.003) and treating pneumothorax (52.94% vs. 37.5%, p = 0.035). However, needle thoracentesis time was slightly longer for the TMS group versus the NTMS group (1:24 ± 1:00 vs. 0:49 ± 0:21 minu, respectively (p = 0.016). Complete treatment time was 12:56 ± 2:58 min for the TMS group, versus 9:33 ± 3:17 min for the NTMS group (p = 0.003). Conclusions: Remote telementoring of basic life support performed by military medics significantly improved the medics' ability to perform an unfamiliar lifesaving procedure at the cost of prolonging time needed to provide care. Future studies must refine the indications and contraindications for using telemedical support.

Abstract
Background: Tension pneumothorax is a frequent cause of potentially preventable death. Tube thoracostomy (TT) can obviate death but is invasive and fraught with complications even in experienced hands. We assessed the utility of a remote international virtual network (RIVN) of specialized mentors to remotely guide military medical technicians (medics) using wireless informatics. Methods: Medics were randomized to insert TT in training mannequins (TraumaMan; Abacus ALS, Meadowbrook, Australia) supervised by RIVN or not. The RIVN consisted of trauma surgeons in Canada and Australia and a senior medic in Ohio. Medics wore a helmet-mounted wireless camera with laser pointer to confirm anatomy and two-way voice communication using commercial software (Skype®). Performance was measured through objective task completion (pass/fail) regarding safety during the procedure, proper location, and secure anchoring of the tube, in addition to remote mentor opinion and subjective debrief. Results: Fourteen medics attempted TT, seven mentored and seven not. The RIVN was functional and surgeons on either side of the globe had real-time communication with the mentees. TT placement was considered safe, successful, and secure in 100% of mentored (n = 7) procedures, although two (29%) received corrective remote guidance. All (100%) of the unmentored attempted and adequately secured the TT and were safe. However, only 71% (n = 5) completed the task successfully (p = 0.46). Participating medics subjectively felt remote telementoring (RTM) increased self-confidence (strong agreement mean 5/5 ± 0); confidence to perform field TT (agreement (4/5 ± 1); and decreased anxiety (strong agreement 5/5 ± 1). Subjectively, the remote mentors felt in 100% of the mentored procedures that "yes" they were able to assist the medics (1.86 ± 0.38), and in 71% (n = 5) felt "yes" they made TT safer (2.29 ± 0.49). Conclusions: RTM descriptively increased the success of TT placement and allowed for real-time troubleshooting from thousands of kilometers with a redundant capability. RTM was subjectively associated with high levels of satisfaction and self-reported self-confidence. Continued controlled and critical evaluation and refinement of telemedical techniques should continue. Trial Registration: ID ISRCTN/77929274.

Abstract
Background Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. Principles of treatment include early antibiotic administration and operative source control. A further therapeutic option may be open abdomen (OA) management with active negative peritoneal pressure therapy (ANPPT) to remove inflammatory ascites and ameliorate the systemic damage from SCIAS. Although there is now a biologic rationale for such an intervention as well as non-standardized and erratic clinical utilization, this remains a novel therapy with potential side effects and clinical equipoise. Methods The Closed Or Open after Laparotomy (COOL) study will constitute a prospective randomized controlled trial that will randomly allocate eligible surgical patients intra-operatively to either formal closure of the fascia or use of the OA with application of an ANPTT dressing. Patients will be eligible if they have free uncontained intra-peritoneal contamination and physiologic derangements exemplified by septic shock OR a Predisposition-Infection-Response-Organ Dysfunction Score ≥ 3 or a World-Society-of-Emergency-Surgery-Sepsis-Severity-Score ≥ 8. The primary outcome will be 90-day survival. Secondary outcomes will be logistical, physiologic, safety, bio-mediators, microbiological, quality of life, and health-care costs. Secondary outcomes will include days free of ICU, ventilation, renal replacement therapy, and hospital at 30 days from the index laparotomy. Physiologic secondary outcomes will include changes in intensive care unit illness severity scores after laparotomy. Bio-mediator outcomes for participating centers will involve measurement of interleukin (IL)-6 and IL-10, procalcitonin, activated protein C (APC), high-mobility group box protein-1, complement factors, and mitochondrial DNA. Economic outcomes will comprise standard costing for utilization of health-care resources. Discussion Although facial closure after SCIAS is considered the current standard of care, many reports are suggesting that OA management may improve outcomes in these patients. This trial will be powered to demonstrate a mortality difference in this highly lethal and morbid condition to ensure critically ill patients are receiving the best care possible and not being harmed by inappropriate therapies based on opinion only.

Abstract
Background Severe complicated intra-abdominal sepsis (SCIAS) is a worldwide challenge with increasing incidence. Open abdomen management with enhanced clearance of fluid and biomediators from the peritoneum is a potential therapy requiring prospective evaluation. Given the complexity of powering multi-center trials, it is essential to recruit an inception cohort sick enough to benefit from the intervention; otherwise, no effect of a potentially beneficial therapy may be apparent. An evaluation of abilities of recognized predictive systems to recognize SCIAS patients was conducted using an existing intra-abdominal sepsis (IAS) database. Methods All consecutive adult patients with a diffuse secondary peritonitis between 2012 and 2013 were collected from a quaternary care hospital in Finland, excluding appendicitis/cholecystitis. From this retrospectively collected database, a target population (93) of those with either ICU admission or mortality were selected. The performance metrics of the Third Consensus Definitions for Sepsis and Septic Shock based on both SOFA and quick SOFA, the World Society of Emergency Surgery Sepsis Severity Score (WSESSSS), the APACHE II score, Manheim Peritonitis Index (MPI), and the Calgary Predisposition, Infection, Response, and Organ dysfunction (CPIRO) score were all tested for their discriminant ability to identify this subgroup with SCIAS and to predict mortality. Results Predictive systems with an area under-the-receiving-operating characteristic (AUC) curve > 0.8 included SOFA, Sepsis-3 definitions, APACHE II, WSESSSS, and CPIRO scores with the overall best for CPIRO. The highest identification rates were SOFA score ≥ 2 (78.4%), followed by the WSESSSS score ≥ 8 (73.1%), SOFA ≥ 3 (75.2%), and APACHE II ≥ 14 (68.8%) identification. Combining the Sepsis-3 septic-shock definition and WSESSS ≥ 8 increased detection to 80%. Including CPIRO score ≥ 3 increased this to 82.8% (Sensitivity-SN; 83% Specificity-SP; 74%. Comparatively, SOFA ≥ 4 and WSESSSS ≥ 8 with or without septic-shock had 83.9% detection (SN; 84%, SP; 75%, 25% mortality). Conclusions No one scoring system behaves perfectly, and all are largely dominated by organ dysfunction. Utilizing combinations of SOFA, CPIRO, and WSESSSS scores in addition to the Sepsis-3 septic shock definition appears to offer the widest "inclusion-criteria" to recognize patients with a high chance of mortality and ICU admission.

Abstract
BACKGROUND Remote-telementored ultrasound involves novice examiners being remotely guided by experts using informatic-technologies. However, requiring a novice to perform ultrasound is a cognitively demanding task exacerbated by unfamiliarity with ultrasound-machine controls. We incorporated a randomized evaluation of using remote control of the ultrasound functionality (knobology) within a study in which the images generated by distant naive examiners were viewed on an ultrasound graphic user interface (GUI) display viewed on laptop computers by mentors in different cities. METHODS Fire-fighters in Edmonton (101) were remotely mentored from Calgary (n = 65), Nanaimo (n = 19), and Memphis (n = 17) to examine an ultrasound phantom randomized to contain free fluid or not. Remote mentors (2 surgeons, 1 internist, and 1 ED physician) were randomly assigned to use GUI knobology control during mentoring (GUIK+/GUIK-). RESULTS Remote-telementored ultrasound was feasible in all cases. Overall accuracy for fluid detection was 97% (confidence interval = 91 to 99%) with 3 false negatives (FNs). Positive/negative likelihood ratios were infinity/0.0625. One FN occurred with the GUIK+ and 2 without (GUIK-). There were no statistical test performance differences in either group (GUIK+ and GUIK-). CONCLUSIONS Ultrasound-naive 1st responders can be remotely mentored with high accuracy, although providing basic remote control of the knobology did not affect outcomes.

Abstract
The term "vestibular compensation" refers to the resolution of motor deficits resulting from a peripheral vestibular lesion. We investigated the role of the cerebellum in the compensation process by characterizing the vestibuloocular reflex (VOR) evoked by head rotations at frequencies and velocities similar to those in natural behaviors in wild-type (WT) versus cerebellar-deficient Lurcher (Lc/+) mice. We found that during exploratory activity, normal mice produce head rotations largely consisting of frequencies < or =4 Hz and velocities and accelerations as large as 400 degrees/s and 5,000 degrees/s2, respectively. Accordingly, the VOR was characterized using sinusoidal rotations (0.2-4 Hz) as well as transient impulses (approximately 400 degrees/s; approximately 2,000 degrees/s2). Before lesions, WT and Lc/+ mice produced similar VOR responses to sinusoidal rotation. Lc/+ mice, however, had significantly reduced gains for transient stimuli. After unilateral labyrinthectomy, VOR recovery followed a similar course for WT and Lc/+ groups during the first week: gain was reduced by 80% for ipsilesionally directed head rotations on day 1 and improved for both strains to values of approximately 0.4 by day 5. Moreover, responses evoked by contralesionally directed rotations returned to prelesion in both strains within this period. However, unlike WT, which showed improving responses to ipsilesionally directed rotations, recovery plateaued after first week for Lc/+ mice. Our results show that despite nearly normal recovery in the acute phase, long-term compensation is compromised in Lc/+. We conclude that cerebellar pathways are critical for long-term restoration of VOR during head rotation toward the lesioned side, while noncerebellar pathways are sufficient to restore proper gaze stabilization during contralesionally directed movements.

Abstract
Experimental measurements of ozone (O3) uptake are needed for validation of dosimetry model parameters and in predictions as well as for determining factors affecting uptake and for making comparisons between subpopulations or across species. In this study, 10 healthy adult male subjects were exposed to 0.3 ppm O3 while seated and breathing naturally through the nose or mouth. Total respiratory tract O3 uptake, spontaneous breathing parameters, and respiratory gas exchange were measured for 10 min under steady-state conditions. The exposure protocol was replicated in each subject approximately 2 weeks after the first visit. On each visit, health exams were performed and spirometric lung measurements were obtained. The experimental design provided comparisons of total O3 uptake during nasal and oral breathing, differences in uptake in an individual at two time points, and an examination of between-subject variability in O3 uptake. Exposure to O3 had no effect on the breathing parameters or gas exchange. Oral and nasal breathing frequency averaged 16.2 +/- 1.1 (SE) and 16.0 +/- 1.2 breaths per minute with tidal volumes averaging 651 +/- 46 and 669 +/- 67 ml, respectively. A significant correlation (p < 0.01) was found for the minute volume during resting breathing with the percentage of uptake. The percentage of O3 uptake was consistently higher (p = 0.02) during oral breathing (76.5% +/- 3.3) than during nasal breathing (73.1% +/- 3.0) although this difference may not be biologically significant. The variability in percentage of uptake between subjects was substantial with calculated uptakes ranging from 51 to 96%, a difference of about 45%. Variability in percentage of uptake for an individual was less with the maximal difference between the first and second visits being about 20%; the average difference, however, was only about 3%. We conclude that total percentage of O3 uptake is approximately 75% in adult males during resting breathing. It is slightly greater during oral than during nasal breathing, will vary considerably among subjects, and is moderately reproducible within a subject.

Abstract
INTRODUCTION The needs of family members of intensive care unit patients are well-documented, but there is little published about the specific needs of family members of air medical patients. PURPOSE This study was devised to identify family member's information needs regarding air medical transport. METHODS Using a descriptive correlational design, 100 family members of air medical patients completed a 14-item Likert-format questionnaire. Each item addressed an information need and asked how important the information was to the family member and how much of this information they received. RESULTS The information needs most frequently ranked as very important related to the patient's condition, the patient's admitting unit at the receiving hospital, and being able to see the patient prior to flight. Information most frequently received by the family related to the patient's condition. CONCLUSION Flight crews need to be cognizant of families' needs and develop ways to improve communication with the family to meet those needs.

Abstract
Acute viral respiratory infections are commonly associated with alteration in lung growth and with chronic obstructive disease. However, it is difficult to quantify these changes in lung function. We determined that the recently described techniques of fractal analysis gave additional information about the changes in lung function after viral illness compared to standard morphometric techniques. Fractal and morphometric parameters change with lung growth after acute infection with canine adenovirus type 2 (CAV2, n = 5) or no infection (controls, n = 6) in beagle puppies. Lung pathological studies showed areas of obliterative bronchiolitis and chronic small airways inflammation but no emphysema in the CAV2-infected puppies. Morphometric studies at approximately 236 days of age demonstrated accelerated lung growth in the CAV2-infected dogs as evidenced by significant increases in lung volume (VL) and internal surface area (ISA). Fractal analysis showed an increased fractal dimension (Df) of the alveolar perimeter length in the CAV2 group associated with increased growth that was similar to the percentage change in VL and ISA. These data suggest that a single infection with CAV2 in beagle puppies accelerates lung growth and increases the complexity (Df) of the alveolar structure.
