Abstract
Abstract
Background
Formal international medical programmes (IMPs) represent an evolution away from traditional medical volunteerism, and are based on the foundation of bidirectional exchange of knowledge, experience and organizational expertise. The intent is to develop multidirectional collaborations and local capacity that is resilient in the face of limited resources. Training and accreditation of surgeons continues to be a challenge to IMPs, including the need for mutual recognition of competencies and professional certification.
Methods
MEDLINE, Embase and Google Scholar™ were searched using the following terms, alone and in combination: ‘credentialing’, ‘education’, ‘global surgery’, ‘international medicine’, ‘international surgery’ and ‘training’. Secondary references cited by original sources were also included. The authors, all members of the American College of Academic International Medicine group, agreed advice on training and accreditation of international surgeons.
Results and conclusion
The following are key elements of training and accrediting international surgeons: basic framework built upon a bidirectional approach; consideration of both high-income and low- and middle-income country perspectives; sourcing funding from current sources based on existing IMPs and networks of IMPs; emphasis on predetermined cultural competencies and a common set of core surgical skills; a decentralized global system for verification and mutual recognition of medical training and certification. The global medical system of the future will require the assurance of high standards for surgical education, training and accreditation.

Abstract
Introduction: Warfarin continues to be widely prescribed for a variety of conditions. It has been shown that preinjury warfarin may worsen outcomes in trauma patients. We hypothesized that a substantial proportion of injured patients seen at our institution were receiving preinjury warfarin for inappropriate indications and that a significant number of such patients had subtherapeutic or supratherapeutic international normalized ratios as well as increased mortality. Materials and Methods: A retrospective review of registry data from a Level I trauma center was conducted for the period from January 2004 to July 2013. Included were patients aged ≥22 years (based on the youngest recorded patient on warfarin in this study). Abstracted variables included patient age, Injury Severity Score (ISS), Maximum Abbreviated Injury Score for Head (MAISH), mortality, hospital length of stay (HLOS), indication(s) for anticoagulant therapy, admission Glasgow Coma Scale (GCS), and admission international normalized ratio (INR). Suitability of warfarin indication(s) was determined using the most recent American College of Chest Physicians (ACCP) Guidelines. Inappropriate warfarin administration was defined as use inconsistent with these guidelines. For outcome comparisons, a case-control design with 1:1 ratio was used, matching patients taking preinjury warfarin to a random sample of trauma patients who were not taking warfarin. Severe traumatic brain injury (sTBI) was defined as MAISH ≥4. Results: A total of 700 out of 14,583 patients aged ≥22 years were receiving preinjury warfarin (4.8% incidence, WG). This group was age- and ISS-matched with 700 patients (4.8% total sample) who were not taking warfarin (NWG) in a total case-control sample of 1,400. The two groups were similar in age, gender, ISS, and initial GCS. According to the ACCP guidelines, 115/700 (16.4%) patients in the warfarin group were receiving anticoagulation for inappropriate indications. Nearly 65% of the patients were outside of their intended INR therapeutic window (43.4% subtherapeutic, 21.6% supratherapeutic). Overall, median HLOS was greater among patients taking preinjury warfarin (4 days vs 2 days, P < 0.010). Mortality was higher in the WG (7.4% or 52/700) than in the NWG (1.9% or 13/700, P < 0.010). Patients with sTBI in the WG had significantly greater mortality (12.8% or 34/266) than those with sTBI in the NWG (5.3% or 9/169, P < 0.013). Conclusion: A significant proportion of trauma patients admitted to our institution were noted to take warfarin for inappropriate indications. Moreover, many patients taking warfarin had either subtherapeutic or supratherapeutic INR. Although warfarin use did not independently predict mortality, preinjury warfarin use was associated with greater mortality and HLOS in the subset of patients with sTBI. Safety initiatives directed at better initiation and management of warfarin are needed.

Abstract
Introduction: Clinical information continues to be limited regarding changes in the temporal risk profile for readmissions during the initial postoperative year in vascular surgery patients. We set out to describe the associations between demographics, clinical outcomes, comorbidity indices, and hospital readmissions in a sample of patients undergoing common extremity revascularization or dialysis access (ERDA) procedures. We hypothesized that factors independently associated with readmission will evolve from “short-term” to “long-term” determinants at 30-, 180-, and 360-day postoperative cutoff points. Methods: Following IRB approval, medical records of patients who underwent ERDA at two institutions were retrospectively reviewed between 2008 and 2014. Abstracted data included patient demographics, procedural characteristics, the American Society of Anesthesiologists score, Goldman Criteria for perioperative cardiac assessment, the Charlson comorbidity index, morbidity, mortality, and readmission (at 30-, 180-, and 360-days). Univariate analyses were performed for readmissions at each specified time point. Variables reaching statistical significance of P < 0.20 were included in multivariate analyses for factors independently associated with readmission. Results: A total of 450 of 744 patients who underwent ERDA with complete medical records were included. Patients underwent either an extremity revascularization (e.g. bypass or endarterectomy, 406/450) or a noncatheter dialysis access procedure (44/450). Sample characteristics included 262 (58.2%) females, mean age 61.4 ± 12.9 years, 63 (14%) emergent procedures, and median operative time 164 min. Median hospital length of stay (index admission) was 4 days. Cumulative readmission rates at 30-, 180-, and 360-day were 12%, 27%, and 35%, respectively. Corresponding mortality rates were 3%, 7%, and 9%. Key factors independently associated with 30-, 180-, and 360-day readmissions evolved over the study period from comorbidity and morbidity-related issues in the short-term to cardiovascular and graft patency issues in the long-term. Any earlier readmission elevated the risk of subsequent readmission. Conclusions: We noted important patterns in the temporal behavior of hospital readmission risk in patients undergoing ERDA. Although factors independently associated with readmission were not surprising (e.g. comorbidity profile, cardiovascular status, and graft patency), the knowledge of temporal trends described in this study may help determine clinical risk profiles for individual patients and guide readmission reduction strategies. These considerations will be increasingly important in the evolving paradigm of value-based healthcare.

Abstract
INTRODUCTION The spleen is one of the most commonly injured abdominal solid organs during blunt trauma. Modern management of splenic trauma has evolved to include non-operative therapies, including observation and angioembolization to preclude splenectomy in most cases of blunt splenic injury. Despite the shift in management strategies, relatively little is known about the hematologic changes associated with these various modalities. The aim of this study was to determine if there are significant differences in hematologic characteristics over time based on the treatment modality employed following splenic trauma. We hypothesized that alterations seen in hematologic parameters would vary between observation (OBS), embolization (EMB), and splenectomy (SPL) in the setting of splenic injury. METHODS An institutional review board-approved, retrospective study of routine hematologic indices examined data between March 2000 and December 2014 at three academic trauma centers. A convenience sample of patients with splenic trauma and admission lengths of stay >96 h was selected for inclusion, resulting in a representative sample of each sub-group (OBS, EMB, and SPL). Basic demographics and injury severity data (ISS) were abstracted. Platelet count, red blood cell (RBC) count and RBC indices, and white blood cell (WBC) count with differential were analyzed between the time of admission and a maximum of 1080 h (45 days) post-injury. Comparisons between OBS, EMB, and SPL groups were then performed using non-parametric statistical testing, with statistical significance set at p < 0.05. RESULTS Data from 130 patients (40 SPL, 40 EMB, and 50 OBS) were analyzed. The median age was 40 years, with 67 % males. Median ISS was 21.5 (21 for SPL, 19 for EMB, and 22 for OBS, p = n/s) and median Glasgow Coma Scale (GCS) was 15. Median splenic injury grade varied by interventional modality (grade 4 for SPL, 3 for EMB, and 2 for OBS, p < 0.05). Inter-group comparisons demonstrated no significant differences in RBC counts. However, mean corpuscular volume (MCV) and RBC distribution width (RDW) were elevated in the SPL and EMB groups (p < 0.01). Similarly, EMB and SPL groups had higher platelet counts than the OBS group (p < 0.01). In aggregate, WBC counts were highest following SPL, followed by EMB and OBS (p < 0.01). Similar trends were noted in neutrophil and monocyte counts (p < 0.01), but not in lymphocyte counts (p = n/s). CONCLUSION This study describes important trends and patterns among fundamental hematologic parameters following traumatic splenic injuries managed with SPL, EMB, or OBS. As expected, observed WBC counts were highest following SPL, then EMB, and finally OBS. No differences were noted in RBC count between the three groups, but RDW was significantly greater following SPL compared to EMB and OBS. We also found that MCV was highest following OBS, when compared to EMB or SPL. Finally, our data indicate that platelet counts are similarly elevated for both SPL and EMB, when compared to the OBS group. These results provide an important foundation for further research in this still relatively unexplored area.

Abstract
BACKGROUND Recent review of older (≥45-years-old) patients admitted to our trauma center showed that more than one-third were using neuro-psychiatric medications (NPMs) prior to their injury-related admission. Previously published data suggests that use of NPMs may increase patients' risk and severity of injury. We sought to examine the impact of pre-injury NPM use on older trauma patients' morbidity and mortality. MATERIALS AND METHODS Retrospective record review included medication regimen characteristics and NPM use (antidepressants-AD, antipsychotics-AP, anxiolytics-AA). Hospital morbidity, mortality, and 90-day survival were examined. Comparisons included regimens involving NPMs, further focusing on their interactions with various cardiac medications (beta blocker - BB; angiotensin-converting enzyme inhibitor/angiotensin receptor blocker - ACE/ARB; calcium channel blocker - CCB). RESULTS 712 patient records were reviewed (399 males, mean age 63.5 years, median ISS 8). 245 patients were taking at least 1 NPM: AD (158), AP (35), or AA (108) before injury. There was no effect of NPM monotherapy on hospital mortality. Patients taking ≥3 NPMs had significantly lower 90-day survival compared to patients taking ≤2 NPMs (81% for 3 or more NPMs, 95% for no NPMs, and 89% 1-2 NPMs, P < 0.01). Several AD-cardiac medication (CM) combinations were associated with increased mortality compared to monotherapy with either agent (BB-AD 14.7% mortality versus 7.0% for AD monotherapy or 4.8% BB monotherapy, P < 0.05). Combinations of ACE/ARB-AA were associated with increased mortality compared to ACE/ARB monotherapy (11.5% vs 4.9, P = 0.04). Finally, ACE/ARB-AD co-administration had higher mortality than ACE/ARB monotherapy (13.5% vs 4.9%, P = 0.01). CONCLUSIONS Large proportion of older trauma patients was using pre-injury NPMs. Several regimens involving NPMs and CMs were associated with increased in-hospital mortality. Additionally, use of ≥3 NPMs was associated with lower 90-day survival.

Abstract
Ultrasound is a ubiquitous and versatile diagnostic tool. In the setting of acute injury, ultrasound enhances the basic trauma evaluation, influences bedside decision-making, and helps determine whether or not an unstable patient requires emergent procedural intervention. Consequently, continued education of surgeons and other acute care practitioners in performing focused emergency ultrasound is of great importance. This article provides a synopsis of focused assessment with sonography for trauma (FAST) and the extended FAST (E-FAST) that incorporates basic thoracic injury assessment. The authors also review key pitfalls, limitations, controversies, and advances related to FAST, E-FAST, and ultrasound education.

Abstract
Ultrasound technology has become ubiquitous in modern medicine. Its applications span the assessment of life-threatening trauma or hemodynamic conditions, to elective procedures such as image-guided peripheral nerve blocks. Sonographers have utilized ultrasound techniques in the pre-hospital setting, emergency departments, operating rooms, intensive care units, outpatient clinics, as well as during mass casualty and disaster management. Currently available ultrasound devices are more affordable, portable, and feature user-friendly interfaces, making them well suited for use in the demanding situation of a mass casualty incident (MCI) or disaster triage. We have reviewed the existing literature regarding the application of sonology in MCI and disaster scenarios, focusing on the most promising and practical ultrasound-based paradigms applicable in these settings.

Abstract
Although chronic hypertension is associated with long-term complications, few studies directly examine the effects of in-hospital acute hypertensive episodes in trauma patients. The aim was to determine whether there is an association between in-hospital acute hypertension and morbidity. We included trauma patients between 45 and 89 years who presented to a level I trauma center between January and September 2008. Patients were classified as either experiencing or not experiencing acute hypertensive episode(s) as defined by systolic blood pressure ≥180, or diastolic blood pressure ≥110 mmHg, or at least two readings of systolic blood pressure ≥160 or diastolic blood pressure ≥100 mmHg. The primary outcome was a composite endpoint of myocardial infarction, stroke, venous thromboembolism, new-onset atrial fibrillation, or acute kidney injury. At least one acute hypertensive episode occurred in 42.6% (69/162) of patients. A total of 10.5% patients developed the composite endpoint, 17.4% in the acute hypertensive episode group compared to 5.4% in the non-hypertensive group, p = 0.012. Patients in the acute hypertensive group were more likely to require an intensive care unit admission compared to the non-hypertensive group (33.3 versus 14.0%, p = 0.004). Of the 17 patients who developed an acute hypertensive episode and met the primary endpoint, 10 were on home antihypertensive medications. Of those, four were restarted on all medications initially, three on some, two were started on new medications, and one was not resumed on home medications. Development of acute hypertensive episode(s) in older trauma patients was associated with an increase in the composite endpoint. Prospective studies are needed.

Abstract
Critical illness polyneuropathy and myopathy is associated with intensive care unit therapies; it is an independent predictor of mortality and will be increasingly affecting the practice of critical care. Most patients with this illness are over 50 years of age, and as our population demographics shift in favor of an aging population, physicians must be aware that this malady will have a rising incidence in the perioperative period. Intensivists, anesthesiologists, surgeons, and geriatricians/internists must remain vigilant. Here we present a concise overview of critical illness polyneuropathy and myopathy, its diagnosis, associations, and possible interventions.

Abstract
Ultrasonography used by practicing clinicians has been shown to be of utility in the evaluation of time-sensitive and critical illnesses in a range of environments, including pre-hospital triage, emergency department, and critical care settings. The increasing availability of light-weight, robust, user-friendly, and low-cost portable ultrasound equipment is particularly suited for use in the physically and temporally challenging environment of a multiple casualty incident (MCI). Currently established ultrasound applications used to identify potentially lethal thoracic or abdominal conditions offer a base upon which rapid, focused protocols using hand-carried emergency ultrasonography could be developed. Following a detailed review of the current use of portable ultrasonography in military and civilian MCI settings, we propose a protocol for sonographic evaluation of the chest, abdomen, vena cava, and extremities for acute triage. The protocol is two-tiered, based on the urgency and technical difficulty of the sonographic examination. In addition to utilization of well-established bedside abdominal and thoracic sonography applications, this protocol incorporates extremity assessment for long-bone fractures. Studies of the proposed protocol will need to be conducted to determine its utility in simulated and actual MCI settings.

Abstract
Despite advances in ventilator management, 31% to 38% of patients with adult respiratory distress syndrome (ARDS) will die, some from progressive respiratory failure. Inability to adequately oxygenate patients with severe ARDS has prompted extensive efforts to identify what are now known as alternative modes of ventilation including high-frequency oscillatory ventilation and airway pressure release ventilation. Both modalities are based on the principles of the open-lung concept and aim to improve oxygenation by keeping the lung uniformly inflated for an extended period of time. Although a mortality benefit has not been proven, some patients may benefit from these alternative modes of ventilation as rescue measures while the underlying process resolves. The purpose of this article is to review the evidence and mechanisms underlying each modality and to describe the fundamental steps in initiating, adjusting, and terminating these modes of ventilation.

Abstract
Given the increasing complexity of both the modern health care environment and the overall patient population, reduction of medical errors is a high priority task for health policy makers and medical/surgical community alike. The problem of retained surgical foreign bodies (RSFB) has existed ever since the humans first performed surgical procedures. Retained surgical foreign bodies continue to be a significant problem with an incidence between 0.3 and 1.0 per 1,000 abdominal operations. Retained surgical foreign bodies have the potential to cause harm to the patient and carry profound professional and medico-legal consequences to surgical trainees, surgical practitioners, hospitals, and health systems. Currently, there are no known methods of entirely eliminating the occurrence of RSFB. In this manuscript, the authors discuss the available evidence with regards to risk factors associated with RSFB as well as methods of minimizing the incidence of RSFB. Modern technological advances designed to decrease the incidence of RSFB (radio-frequency tagging of surgical sponges) and improved perioperative patient processing (multiple 'checks and balances' and better provider-to-provider communication) are reviewed. The authors also explore the relationship between RSFB and surgical training with emphasis on education in early recognition, prevention, and focus on team-oriented training strategies.

Abstract
Pancreatic injuries are rare, with penetrating mechanisms being causative in majority of cases. They can create major diagnostic and therapeutic challenges and require multiple diagnostic modalities, including multislice high-definition computed tomography, magnetic resonance cholangiopancreatography, endoscopic retrograde cholangiopancreatography, ultrasonography, and at times, surgery and direct visualization of the pancreas. Pancreatic trauma is frequently associated with duodenal and other severe vascular and visceral injuries. Mortality is high and usually related to the concomitant vascular injury. Surgical management of pancreatic and pancreatic-duodenal trauma is challenging, and multiple surgical approaches and techniques have been described, up to and including pancreatic damage control and later resection and reconstruction. Wide surgical drainage is a key to any surgical trauma technique and access for enteral nutrition, or occasionally parenteral nutrition, are important adjuncts. Morbidity associated with pancreatic trauma is high and can be quite severe. Treatment of pancreatic trauma-related complications often requires a combination of interventional, endoscopic, and surgical approaches.

Abstract
Deep venous thrombosis and pulmonary embolism constitute common preventable causes of morbidity and mortality. The incidence of venous thromboembolism (VTE) continues to increase. Standard anticoagulation therapy may reduce the risk of fatal PE by 75% and that of recurrent VTE by over 90%. For patients who are not candidates for anticoagulation, a vena cava filter (VCF) may be beneficial. Despite a good overall safety record, significant complications related to VCF are occasionally seen. This review discusses both procedural and non-procedural complications associated with VCF placement and use. We will also discuss VCF use in the settings of pregnancy, malignancy, and the clinical need for more than one filter.

Abstract
The surgical specialty of critical care has evolved into a field where the surgeon manages complex medical and surgical problems in critically ill patients. As a specialty, surgical critical care began when acutely ill surgical patients were placed in a designated area within a hospital to facilitate the delivery of medical care. As technology evolved to allow for development of increasingly intricate and sophisticated adjuncts to care, there has been recognition of the importance of physician availability and continuity of care as key factors in improving patient outcomes. Guidelines and protocols have been established to ensure quality improvement and are essential to licensing by state and national agencies. The modern ICU team provides continuous daily care to the patient in close communication with the primary operating physician. While the ultimate responsibility befalls the primary physician who performed the preoperative evaluation and operative procedure, the intensivist is expected to establish and enforce protocols, guidelines and patient care pathways for the critical care unit. It is difficult to imagine modern surgical ICU care without the surgical critical care specialist at the helm.

Abstract
BACKGROUND Sestamibi imaging is the most widely used preoperative localization study for patients with hyperparathyroidism. Previous reports examine the relationship between the weight and volume of excised parathyroid glands and preoperative serum calcium and parathyroid hormone (PTH) levels. The aim of this study was to examine whether these variables correlate with the results of preoperative Sestamibi scans. MATERIAL AND METHODS A retrospective review of 150 consecutive patients who underwent preoperative sestamibi imaging for primary hyperparathyroidism between 1998 and 2007 was performed. Variables studied included patient demographics, diagnostic test (sestamibi) results, operative/pathology findings and surgical outcome (normocalcaemia vs. persistent hypercalcaemia). Sestamibi scans were designated as either "negative" (NSS) or "positive" (PSS), where PSS correctly localized abnormal gland(s) enabling a focused neck exploration. The results of sestamibi imaging were correlated with calcium/PTH levels, weight/volume of excised glands and patient outcomes and demographics. RESULTS Total excised gland weight/volume and preoperative serum calcium levels were significantly higher with PSS (all, p < 0.04). Higher preoperative serum calcium levels and greater total gland weight/volume were significantly associated with successful operative outcome (presence of postoperative normocalcaemia; all, p < 0.01). Factors associated with operative failure included multi-gland disease (p < 0.01) and NSS (p < < 0.01). Higher diagnostic PTH levels (> 150 pg/mL) were associated with greater excised gland mass (p < 0.05) and volume (p < 0.05). Male gender was associated with higher preoperative serum calcium levels (p < 0.02). Of interest, patients with single-gland disease had significantly higher preoperative PTH levels than patients with multi-gland disease (155 vs. 109 pg/mL, p < 0.05). CONCLUSION Positive sestamibi scans are associated with heavier/larger parathyroid glands and higher preoperative serum calcium levels. Male gender was associated with higher preoperative serum calcium levels, while single-gland disease was associated with higher preoperative PTH levels. In addition, successful surgical outcome was associated with higher preoperative serum calcium levels and with greater excised parathyroid gland mass/volume. Surgical failure was associated with multi-gland disease and negative sestamibi.

Abstract
Spontaneous renal artery dissection (SRAD) is rare. Clinical manifestations vary from minimal symptoms to life-threatening hypertension. We analysed three cases from our institution and conducted a literature review in order to design diagnostic and treatment algorithms for SRAD.
