RESUMEN
PURPOSE: Despite the availability of clinical guidelines for hip fracture patients, adherence to these guidelines is challenging, potentially resulting in suboptimal patient care. The goal of this study was (1) to evaluate and benchmark the adherence to recently established quality indicators (QIs), and (2) to study clinical outcomes, in fragile hip fracture patients from different European countries. METHODS: This observational, cross-sectional multicenter study was performed in 10 hospitals from 9 European countries including data of 298 consecutive patients. RESULTS: A large variation both within and between hospitals were seen regarding adherence to the individual QIs. QIs with the lowest overall adherence rates were the administration of systemic steroids (5.4%) and tranexamic acid (20.1%). Indicators with the highest adherence rates (above 95%) were pre-operative (99.3%) and post-operative haemoglobin level assessment (100%). The overall median time to surgery was 22.6 h (range 15.7-42.5 h). The median LOS was 9.0 days (range 5.0-19.0 days). The most common complications were delirium (23.2%) and postsurgical constipation (25.2%). CONCLUSION: The present study shows large variation in the care for fragile patients with hip fractures indicating room for improvement. Therefore, hospitals should invest in benchmarking and knowledge-sharing. Large quality improvement initiatives with longitudinal follow up of both process and outcome indicators should be initiated.
RESUMEN
Tibial plateau fractures are often complex injuries that result from high-energy trauma affecting the articular congruity of the knee. Managing tibial plateau fractures can be challenging because of severe depression of the subchondral cancellous bone and concomitant cartilage injury. Bone substitutes are commonly used to fill such defects as part of the surgical treatment of tibial plateau fractures. We describe three cases of tibial plateau fractures managed with a synthetic bone substitute (b.Bone™, GreenBone ORTHO S.p.A Faenza, Italy) with a highly interconnected and porous 3D structure to mimic the hierarchical architecture and morphology of natural human bone.
RESUMEN
INTRODUCTION: Occult hypoperfusion (OH) entails inadequate tissue oxygenation in the presence of normal vital signs. Numerous studies have demonstrated that this phenomenon is associated with impaired outcome and increased mortality, however definitions of OH differ between studies. The aim of the current study was to identify and evaluate the published definitions of the term `occult hypoperfusion` in trauma (tOH). MATERIAL & METHODS: A review of literature was performed using the Medline database. The following MeSH terms have been used: occult hypoperfusion, severe trauma, polytrauma, resuscitation. Clinical studies on OH were included and utilized definitions have been compared. A predefined data-interpretation process was applied to create an integrative definition for tOH. RESULTS: A total of 43 publications used the term OH. A definition of OH was provided in 16 manuscripts. A pooled mean number of participants of 729 (SD: 1158) was found per study. The majority of manuscripts combine multiple parameters for inadequate tissue oxygenation and normal vital signs to define OH in trauma. In 12 manuscripts, specific cut-off values for hemodynamic parameters (SBP/PR/UP) and in 11/16 papers exact metabolic thresholds (lactate/B.E) were defined. The following definition best integrates definitions in current literature: Lactate > 2 mmol/l or BE <-3 mmol/l (to define inadequate oxygenation) plus SBP > 90 mmHg and PR < 120 bpm (to define normal macroperfusion). CONCLUSIONS: The current systematic review demonstrates that definitions of occult hypoperfusion in trauma differ in the literature. The following comprehensive definition for (tOH) is proposed: Lactate > 2 mmol/l or BE <-3 mmol/l plus SBP > 90 mmHg and PR < 120 bpm. This recommendation appears to represent current literature on tOH and may improve the identification of trauma patients at risk for OH and related complicated courses. Further validation studies are required to demonstrate the clinical role of tOH and the proposed definition.

Acute compartment syndrome of the extremities is a surgical emergency and a rapid diagnosis and immediate surgical treatment are essential for the outcome. The cause is an increase in the tissue pressure inside a muscle compartment enclosed by fasciae and the resulting disruption of microperfusion. This can have potentially disastrous consequences, such as loss of the extremity due to extensive tissue necrosis or a threat to life due to infectious complications. Although mostly triggered by trauma, a multitude of other causes can lead to the formation of a compartment syndrome, so that a basic knowledge of this condition is of great importance not only for trauma surgeons. This is particularly true because a timely treatment necessitates rapid diagnosis and evaluation of the indications. This article provides an overview of the underlying pathophysiology, the causes, the symptoms and the treatment of acute compartment syndrome.

The pathophysiology after polytrauma represents a complex network of interactions. While it was thought for a long time that the direct and indirect effects of hypoperfusion are most relevant due to the endothelial permeability changes, it was discovered that the innate immune response to trauma is equally important in modifying the organ response. Recent multi center studies provided a "genetic storm" theory, according to which certain neutrophil changes are activated at the time of injury. However, a second hit phenomenon can be induced by activation of certain molecules by direct organ injury, or pathogens (damage associated molecular patterns, DAMPS - pathogen associated molecular patterns, PAMPS). The interactions between the four pathogenetic cycles (of shock, coagulopathy, temperature loss and soft tissue injuries) and cross-talk between coagulation and inflammation have also been identified as important modifiers of the clinical status. In a similar fashion, overzealous surgeries and their associated soft tissue injury and blood loss can induce secondary worsening of the patient condition. Therefore, staged surgeries in certain indications represent an important alternative, to allow for performing a "safe definitive surgery" strategy for major fractures. The current review summarizes all these situations in a detailed fashion.

PURPOSE: The number of severely injured patients exceeding the age of 60 has shown a steep increase within the last decades. These patients present with numerous co-morbidities, polypharmacy, and increased frailty requiring an adjusted treatment approach. In this study, we establish an overview of changes we observed in demographics of older severe trauma patients from 2002 to 2017. METHODS: A descriptive analysis of the data from the TraumaRegister DGU® (TR-DGU) was performed. Patients admitted to a level one trauma center in Germany, Austria and Switzerland between 2002 and 2017, aged 60 years or older and with an injury severity score (ISS) over 15 were included. Patients were stratified into subgroups based on the admission: 2002-2005 (1), 2006-2009 (2), 2010-2013 (3) and 2014-2017 (4). Trauma and patient characteristics, diagnostics, treatment and outcome were compared. RESULTS: In total 27,049 patients with an average age of 73.9 years met the inclusion criteria. The majority were males (64%), and the mean ISS was 27.4. The proportion of patients 60 years or older [(23% (1) to 40% (4)] rose considerably over time. Trauma mechanisms changed over time and more specifically low falls (< 3 m) rose from 17.6% (1) to 40.1% (4). Altered injury patterns were also identified. Length-of-stay decreased from 28.9 (1) to 19.5 days (4) and the length-of-stay on ICU decreased from 17.1 (1) to 12.7 days (4). Mortality decreased from 40.5% (1) to 31.8% (4). CONCLUSION: Length of stay and mortality decreased despite an increase in patient age. We ascribe this observation mainly to increased use of diagnostic tools, improved treatment algorithms, and the implementation of specialized trauma centers for older patients allowing interdisciplinary care.

Treatment resistance of anxiety-related disorders often arises from an inappropriate fear expression, impairment in fear extinction, and spontaneous return of fear. Stress exposure is considered a high risk factor for neuropsychiatric disorders, but understanding of the long-term consequences of stress is limited, particularly when it comes to treatment outcome. Therefore, studying the consequences of acute stress would provide critical information on the role of stress in psychopathology. In the present study, we investigated the effect of acute immobilization stress on anxiety-like behavior and on conditioned fear memory. Our results demonstrate that prior stress exposure had no effect on anxiety-related behavior, fear acquisition, as well as fear extinction compared to non-stressed controls, but resulted in significantly higher rates of freezing during recall of extinction, indicating a consolidation failure. Further, immunohistochemical analysis of the expression of the immediate early gene c-Fos after recall of extinction revealed increased neuronal activity in the posterior paraventricular nucleus of the thalamus (PVT) in previously stressed animals compared to non-stressed controls. These results indicate, firstly, that acute stress affects long-term fear memory even after successful extinction training, and secondly, a strong involvement of the PVT in maladaptive fear responses induced by prior stress. Thus, stress-induced changes in PVT neuronal activity might be of importance for the pathophysiology of stress-sensitive anxiety-related psychiatric disorders, since exposure to an earlier acute stressor could counteract the success of therapy.

RESUMEN
INTRODUCTION: False traumatic aneurysm (FTA) or pseudoaneurysm and traumatic arteriovenous fistulas (TAVF) are rare pathologies in civilian trauma and mainly result from stabs or gunshot wounds. The posterior tibial artery as site of trauma is very rare. PRESENTATION OF CASE: We report on a 39-year old female patient who was suffering from combined FTA and TAVF of the posterior tibial artery after falling into a wine glass. CT-imaging as well as duplex ultrasound and selective arteriography were performed, and two stent-grafts were inserted. DISCUSSION: Based on the presented case, incidence of the described pathology, treatment options and outcomes are discussed. CONCLUSION: Adequate imaging in penetrating wounds to the extremities is crucial in order to provide diagnosis and treatment of concomitant lesions.
RESUMEN
Brain µ-opioid receptors (MOR) mediate reward and help coping with pain, social rejection, anxiety and depression. The dorsal midline thalamus (dMT) integrates visceral/emotional signals and biases behavior towards aversive or defensive states through projections to the amygdala. While a dense MOR expression in the dMT has been described, the exact cellular and synaptic mechanisms of µ-opioidergic modulation in the dMT-amygdala circuitry remain unresolved. Here, we hypothesized that MORs are important negative modulators of dMT-amygdala excitatory networks. Using retrograde tracers and targeted channelrhodopsin expression in combination with patch-clamp electrophysiology, we found that projections of dMT neurons onto both basal amygdala principal neurons (BA PN) and central amygdala (CeL) neurons are attenuated by stimulation of somatic or synaptic MORs. Importantly, dMT efferents to the amygdala drive feedforward excitation of centromedial amygdala neurons (CeM), which is dampened by MOR activation. This downregulation of excitatory activity in dMT-amygdala networks puts the µ-opioid system in a position to ameliorate aversive or defensive behavioral states associated with stress, withdrawal, physical pain or social rejection.

OBJECTIVES: Sustained changes in resuscitation and transfusion management have been observed since the turn of the millennium, along with an ongoing discussion of surgical management strategies. The aims of this study are threefold: a) to evaluate the objective changes in resuscitation and mass transfusion protocols undertaken in major level I trauma centers; b) to summarize the improvements in diagnostic options for early risk profiling in multiply injured patients and c) to assess the improvements in surgical treatment for acute major fractures in the multiply injured patient. METHODS: I. A systematic review of the literature (comprehensive search of the MEDLINE, Embase, PubMed, and Cochrane Central Register of Controlled Trials databases) and a concomitant data base (from a single Level I center) analysis were performed. Two authors independently extracted data using a pre-designed form. A pooled analysis was performed to determine the changes in the management of polytraumatized patients after the change of the millennium. II. A data base from a level I trauma center was utilized to test any effects of treatment changes on outcome. INCLUSION CRITERIA: adult patients, ISS > 16, admission < less than 24 h post trauma. Exclusion: Oncological diseases, genetic disorders that affect the musculoskeletal system. Parameters evaluated were mortality, ICU stay, ICU complications (Sepsis, Pneumonia, Multiple organ failure). RESULTS: I. From the electronic databases, 5141 articles were deemed to be relevant. 169 articles met the inclusion criteria and a manual review of reference lists of key articles identified an additional 22 articles. II. Out of 3668 patients, 2694 (73.4%) were male, the mean ISS was 28.2 (SD 15.1), mean NISS was 37.2 points (SD 17.4 points) and the average length of stay was 17.0 days (SD 18.7 days) with a mean length of ICU stay of 8.2 days (SD 10.5 days), and a mean ventilation time of 5.1 days (SD 8.1 days). Both surgical management and nonsurgical strategies have changed over time. Damage control resuscitation, dynamic analyses of coagulopathy and lactate clearance proved to sharpen the view of the worsening trauma patient and facilitated the prevention of further complications. The subsequent surgical care has become safer and more balanced, avoiding overzealous initial surgeries, while performing early fixation, when patients are physiologically stable or rapidly improving. Severe chest trauma and soft tissue injuries require further evaluation. CONCLUSIONS: Multiple changes in management (resuscitation, transfusion protocols and balanced surgical care) have taken place. Moreover, improvement in mortality rates and complications associated with several factors were also observed. These findings support the view that the management of polytrauma patients has been substantially improved over the past 3 decades.

A Patient Blood Management programme was established at the University Hospital of Zurich, along with a monitoring and feedback programme, at the beginning of 2014 with a first analysis reported in 2015. Our study aimed to investigate the further impact of this Patient Blood Management monitoring and feedback programme on transfusion requirements and related costs. We included adult patients discharged between 2012 and 2017. A total of 213,882 patients underwent analysis: 66,659 patients in the baseline period (2012-2013); 35,309 patients in the year after the introduction of the Patient Blood Management monitoring and feedback programme (2014) and 111,914 patients in the continued sustainability period (2015-2017). The introduction of the Patient Blood Management monitoring and feedback programme reduced allogeneic blood product transfusions by 35%, from 825 units per 1000 hospital discharges in 2012 to 536 units in 2017. The most sustained effect was an approximately 40% reduction in red blood cell transfusions, from 535 per 1000 discharges to 319 units. Fewer patients were transfused in the periods after the introduction of the Patient Blood Management monitoring and feedback programme (6251 (9.4%) vs. 2932 (8.3%) vs. 8196 (7.3%); p < 0.001). Compared with 2012, the yearly OR for being exposed to any blood transfusion declined steadily after the introduction of the Patient Blood Management monitoring and feedback programme to 0.64 (95%CI 0.61-0.68; p < 0.001) in 2017. For patients requiring extracorporeal membrane oxygenation, transfusion requirements were also sustainably reduced. This reduction in allogeneic blood transfusions led to savings of 12,713,754 Swiss francs (£ 9,497,000 sterling; EUR 11,100,000; US$ 12,440,000) in blood product acquisition costs over 4 years. In-hospital mortality was not affected by the programme. The Patient Blood Management monitoring and feedback programme sustainably reduced transfusion requirements and related costs, without affecting in-hospital mortality.

BACKGROUND: Injuries to the acromioclavicular (AC) joint are one of the most common among sporting injuries of the upper extremity. Several studies investigated different treatment options comparing surgical and non-surgical treatment, and type of operative interventions. This study aims to evaluate treatment decisions regarding injuries of the AC joint and to compare different treatment strategies depending on the specific training of the treating physician. METHODS: We performed a nationwide survey by contacting different experienced physicians and sending them questionnaires. The questionnaire included 37 questions that assessed preferred treatment strategies in AC joint injuries. We addressed different surgical and nonsurgical options as well as level of experience and factors that might influence the decision on treatment strategy. The physicians were stratified according to their training into general surgeons (group trauma associated) and orthopedic surgeons (orthopedic associated). The AC joint lesions were categorized according to the widely used Rockwood classification. RESULTS: This study analyses 96 questionnaires. We included 46 (47.9%) colleagues in group trauma and 50 (52.1%) in group orthopedics. Most of the colleagues (98.9%) prefer non-operative treatment of type I and type II AC lesions. Similarly, 96.8% agree on surgical treatment of types IV, V, and VI lesions. The treatment of type III lesions is performed in 41.6% of cases non-operatively and in 58.4% of cases surgically. Trauma-associated colleagues are 3.4 times more likely to treat AC lesions with a hook plate compared to orthopedic-associated colleagues (p = 0.05). In decreasing order, the most commonly used non-surgical technique is sling immobilization (63.7%), and the most commonly performed surgical treatment is the hook plate (41.1%) in treating type III injuries. CONCLUSION: This study shows a distinct difference in treatment of AC joint injuries depending on the training of the physician. Further, the need for high-quality studies arises to define the optimal treatment of type III lesions.

PURPOSE: To test the effects of vitamin D intervention and a simple home exercise program (HE) on health-related quality of life (HRQL) in the first 12 months after hip fracture. METHODS: HRQL was reported in 173 acute hip fracture patients (mean age 84 years, 79% females, 77% community dwelling) who were enrolled in the 12-month 2 × 2 factorial Zurich Hip Fracture Trial. Pre-fracture HRQL was assessed at baseline (4.2 ± 2.2 days post-surgery) and then again at 6 and 12 months after hip fracture surgery by the EuroQol EQ-5D-3L index value (EQ-5D-3L questionnaire). The effects of vitamin D intervention (2000 vs. 800 IU vitamin D3) and exercise (HE vs. no HE) or of the combined interventions on HRQL were assessed using multivariable-adjusted repeated-measures linear mixed-effects regression models. RESULTS: The EQ-5D-3L index value significantly worsened from 0.71 pre-fracture to 0.57 over 12 months, but the degree of worsening did not differ between individual or combined interventions. However, regarding only the late recovery between 6 and 12 months, the group receiving neither intervention (800 IU/day and no HE) experienced a significant further decline in the EQ-5D-3L index value (adjusted mean change = 0.08 [95% CI 0.009, 0.15], p = 0.03) while all other groups remained stable. CONCLUSION: Hip fractures have a long-lasting negative effect on HRQL up to 12 months after hip fracture. However, HE and/or 2000 IU vitamin D per day may help prevent a further decline in HRQL after the first 6 months following the acute hip fracture event.

BACKGROUND: An individual's risk of falling is generally difficult to detect and it is likely to be underestimated. Thus, preventive measures are challenging and they demand sufficient integration and implementation into aftercare and outpatient management. The Aachen Falls Prevention Scale (AFPS) is a quick and easy tool for patient-driven fall risk assessment. Older adults' risk of falling is identified in a suitable manner and they then have the opportunity to independently assess and monitor their risk of falling. OBJECTIVES: The aim of the current study was to evaluate the AFPS as a simple screening tool in geriatric trauma patients via the identification of influencing factors, e.g. objective or subjective fall risk, fear of falling (FOF) and demographic data. In this context, we investigated older adults' willingness to take part in special activities concerning fall prevention. METHODS: Retrospectively, all patients over 70 years of age who received in-hospital fracture treatment between July 2014 and April 2016 were analyzed at a level I trauma center. After identification of 884 patients, participants completed a short questionnaire (47 questions, yes/no, Likert scale) comprising the AFPS. A history of falls in the past year was considered an indicator of a balance disorder. In addition, ambulant patients were invited to participate between July and August 2016. RESULTS: In total, 201 patients (mean 80.4 years, range 63-97 years) performed a self-assessment based on the AFPS. After steps 1 and 2 of the AFPS had been completed, 95 (47%) participants rated their subjective risk of falling as high (more than 5 points). Of the participants 84 (42%) were objectively classified as "fallers" with significant effects on their AFPS evaluation and rating of their subjective risk of falling. Furthermore, 67% of the participants identified a general practitioner as their main contact person, and 43% of the respondents viewed the AFPS as a beneficial screening tool in fall risk evaluation (8% negative attitudes). Only 12% of the participants could imagine using the AFPS app version as a feasible option. CONCLUSION: It would be advantageous to pretest at-risk individuals in their environment using a simple self-assessment approach, with the main purpose of identifying potential balance problems. With this approach, cost savings in the healthcare system are possible, combined with a higher health-related quality of life in the geriatric population.

Abdominal injuries are potentially life-threatening and occur in 20-25% of all polytraumatized patients. Blunt trauma is the main mechanism. The liver and spleen are most commonly injured and much less often the intestines. The clinical evaluation proves equivocal in many cases; therefore, the gold standard is computed tomography (CT), which has been increasingly used even in hemodynamically weakly stable or sometimes even unstable patients because it promptly provides precise diagnostic findings, which present the basis for successful therapy. Hemodynamically unstable patients always need an exploratory laparotomy (EL). An EL should also be carried out with a positive focused assessment with sonography for trauma (FAST) or CT for severe parenchymal lesions, hollow organ lesions, intraperitoneal bladder lesions, peritonitis and organ evisceration, impalement injuries and lesions of the abdominal fascia. Hemodynamically stable patients without signs of peritonitis and a lack of such findings can often be treated conservatively irrespective of the extent of an injury. Angiography (and if needed embolization) can additionally be diagnostically and therapeutically utilized.

PURPOSE: This review gives an overview of physiological processes, mainly regarding vascular endothelial cells and their important role in hemostasis, information processing, and communication during trauma. An insight is given into molecules and cells involved in the first innate immune response through to the behavior of endothelial cells in developing trauma. The goal of this review is to show the overlap of crucial factors related to the endothelium and the development of trauma. METHODS: A systemic literature search was performed using Google scholar and PubMed. RESULTS: The results of the literature search showed that the endothelium, especially the vascular endothelium, is involved in various cellular and subcellular pathways of activation, suppression, and transfer of information. A variety of molecules and cells are orchestrated, subsequently the endothelium gets in contact with a traumatizing event. CONCLUSION: The endothelium is one of the first barriers that comes into contact with exo- and endogenous trauma-related signals and is a pivotal point in activating subsequent pathways and cascades by transfer of information.
