Rib fractures are a frequent occurrence in trauma victims. Patients with a “flail chest” pattern of injury, defined as two fractures per rib in three (or more) consecutive ribs, often struggle with hypoxemic respiratory failure related to inefficient ventilatory mechanics, inability to expectorate, underlying pulmonary contusion and subsequent pneumonia. The operative indications for rib fracture repair have not been established and are considered to be an issue of debate. Over the last ten years, surgical stabilization of rib fractures has emerged as a promising therapy for patients with severe chest wall injuries. When surgical treatment is performed for patients with rib fracture, general anesthesia is the gold standard but, considered the patients clinical condition, we decided to perform the surgery with regional anesthesia and awake patients to avoid risk of ventilator-induced lung injury. Epidural anesthesia, thoracic paravertebral block and erector spinae plane block for analgesia in patients with rib fractures have been reported. In our report, we discussed the use of ultrasound-guided thoracic paravertebral block with administration of local anesthetic posteriorly to superior costo-transverse ligament and erector spinae plane block to perform surgical stabilization of rib fractures.

Mediastinitis secondary to esophageal perforation is a rare, progressive, and destructive disease that may often lead to an imminent risk of death. We describe a single center experience showing how early diagnosis and prompt intervention can reduce mortality and complications. Methods From February 2016 to December 2019, 15 consecutive patients were referred to the Emergency Unit of The AORN Cardarelli (Naples) with clinical and radiological (CT scan) diagnosis of acute mediastinitis secondary to oesophageal perforation (post endoscopy or after foreign body ingestion) and furthermore, referred to the Thoracic Surgery Unit, they underwent to early surgical treatment (cervicotomy and\or thoracotomy and chest drainage. Results For early detected case (occurred within 24 hours) an emergency thoracotomy/cervicotomy was performed with surgical repair. For late detected (referred from other hospitals) a Surgical esclusion (abdominal plus cervical) and toilette thoracotomy was performed in emergency. Reconstruction occurred in 5 cases with a median of 46 days after firts care. All patient were admitted to ICU unit and susbsequentily to the thoracic surgery ward. 30 days mortality occurred in two cases. Median hospital staying was 28 days, in six cases a redo surgery was necessary. Empiric antibiotic treatment was started before operation and reviewed under Infectivologist. Conclusion Mediastinitis secondary to esophageal perforation has a fulminating course with a potential risk of sepsis, pericarditis, and multiple organ failure. A prompt identification and an invasive treatment is the best and most successful option to reduce mortality and improve patient’s recovery.

Background Major trauma patients experience a 20% mortality rate overall, and many survivors remain permanently disabled. In order to monitor the quality of trauma care in the Trauma System, outcomes assessment is essential. Quality indicators on outcome can be expressed as quality of life, functional outcome, and others. The trauma follow-up system was created within the Romagna Trauma System (Italy) in order to monitor the trauma network and assess its long-term outcomes. The aim of this paper is firstly to evaluate the existence of correlations between epidemiological data, severity of injury, and clinical assessment characterizing the acute phase and the long-term outcomes in trauma patients and secondly, to explore the association between outcome variables have been modified. Methods We conducted a cross-sectional study over a 10-year period, including patients with severe trauma who survived and were discharged from the intensive care unit. The outcome measures were assessed with the use of the Extended Glasgow Outcome Scale and the Euro Quality of Life scale 5 dimension. Demographic data and clinical severity descriptors versus functional outcome were tested in a binary logistic regression model. Results In all, 428 major trauma patients participated in the study. At 1 year, 50.8% of trauma patients included had a good recovery and 49.2% had some degree of disability. The median value of quality of life was 0.725. At the multivariate analysis, variables showing significant impact on functional outcome were age (p = 0.052, OR 1.025), injury severity score (p = 0.001, OR 1.025), and Glasgow coma scale ≤ 8 (p = 0.001, OR 3.509) The Spearman’s Rank correlation coefficient showed a strong correlation between the global level of function variables and quality of life at one year (Spearman’s Rho Correlation Coefficient 0.760 (p < 0.0001)). Conclusions Increased age, increased injury severity score, and severe traumatic brain injury are predictors of long-term disability. Most of these trauma patients show impairments that affect not only the level of functional state but also the quality of life. The degree of functional independence has the greatest positive impact on quality of life. According to our results, after the recovery a prompt recognition of physical and psychological problems with systematic follow-up screening programs can help patients and doctors in defining specific therapeutic-rehabilitation pathways tailored to meet individual requirements.

Introduction The management of complex trauma patient with concomitant brain injury and extra-cranial lesions is challenging since the requirement of a low pressure to limit the bleeding clashes with the need to maintain an adequate cerebral perfusion and to obtain a brain CT-scan. Here we present the use of REBOA as a bridge to CT scan in complex head and torso trauma. Case presentation A 59-years male patient involved in a car accident was admitted to our hospital after a car accident. He had a GCS of 3 with a left fixed pupil anisocoria. Despite right-sided chest decompression for pneumothorax and massive transfusion protocol for hemoperitoneum, blood pressure remained low; to temporally stabilize the patient and perform a brain CT scan a zone 1 REBOA was inserted and systolic blood pressure rose up from 60 mmHg to 110 mmHg. A brain CT scan highlighted a right subdural hematoma with a 8-mm midline shift. The patient went to the operating room to perform damage control surgery and, subsequently, a decompressive craniotomy. After 96 days of hospital stay, the patient was discharged at home with a complete neurological recovery. Conclusions The achievement of a rapid brain CT scan in traumatic brain injury is often crucial and has a deep impact in changing surgical management; moreover, duration of cerebral herniation is associated with worse outcome and increased mortality. In the light of this, the use of REBOA in selected cases of complex head and torso trauma could allow to gain time to go to the CT room in safe conditions.

The intracranial compartment syndrome is a condition characterized by a set of clinical symptoms and signs due to a rise in intracranial pressure (ICP). Intracranial hypertension is a life-treating condition that requires quick diagnosis and treatment; otherwise, it may progress in herniation syndrome and death. Consequently, timely recognition and management of elevated ICP is the first goal in order to maintain good cerebral perfusion pressure and to prevent irreversible secondary cerebral insult. Several pathologies may cause raised ICP, and it is fundamental to treat the specific underlying disease. Therefore, neuromonitoring assumes paramount significance for the rapid detection of harmful events and for a quick evaluation of the efficacy of medical treatment. In this chapter, we aimed to provide an overview of the current knowledge regarding the diagnosis and treatment of intracranial compartment syndrome.

Thoracoscopic lobectomy (VATS-L) for non-small-cell lung cancer (NSCLC) is a well-established option for early stage NSCLC, but the evidences are limited for octogenarians.The objectives of this multi-institutional study were to evaluate the post-operative outcomes of VATS-L in octogenarians and to estimate the post-operative quality of life (QoL) using a validated questionnaire (EuroQoL5D).Data from patients underwent VATS-L between 2014 and 2019 were analysed and divided into two groups: Group A (younger patients) and Group B (octogenarians). To define predictors for complications, univariate and multivariable logistic regression analysis were performed.7023 patients underwent VATS-L and 329 (4.6%) were octogenarians. 30-day and 90-day post-operative mortality were similar (0.95% vs 0.91%, p = 0.84 and 1.3% vs 1.2%, p = 0.58), whereas the percentage of patients who suffered from any complication (25.5% vs 31.9%, p = 0.012) and the complication rate (31.6% vs 45.2%, p=0.01) were higher for octogenarians. At discharge, the values of EuroQoL5D were worse in group B, but after one month these levels became similar. Age80 years had a significant influence on morbidity on both univariate and multivariable analyses (p = 0.025).VATS-L for NSCLC can be performed in selected octogenarians without increased risk of post-operative death, acceptable not-life-threatening complications and a moderate impact on QoL.

Background Health-related quality of life (HRQoL) impairment is often reported among COVID-19 ICU survivors, and little is known about their long-term outcomes. We evaluated the HRQoL trajectories between 3 months and 1 year after ICU discharge, the factors influencing these trajectories and the presence of clusters of HRQoL profiles in a population of COVID-19 patients who underwent invasive mechanical ventilation (IMV). Moreover, pathophysiological correlations of residual dyspnea were tested. Methods We followed up 178 survivors from 16 Italian ICUs up to one year after ICU discharge. HRQoL was investigated through the 15D instrument. Available pulmonary function tests (PFTs) and chest CT scans at 1 year were also collected. A linear mixed-effects model was adopted to identify factors associated with different HRQoL trajectories and a two-step cluster analysis was performed to identify HRQoL clusters. Results We found that HRQoL increased during the study period, especially for the significant increase of the physical dimensions, while the mental dimensions and dyspnea remained substantially unchanged. Four main 15D profiles were identified: full recovery (47.2%), bad recovery (5.1%) and two partial recovery clusters with mostly physical (9.6%) or mental (38.2%) dimensions affected. Gender, duration of IMV and number of comorbidities significantly influenced HRQoL trajectories. Persistent dyspnea was reported in 58.4% of patients, and weakly, but significantly, correlated with both DLCO and length of IMV. Conclusions HRQoL impairment is frequent 1 year after ICU discharge, and the lowest recovery is found in the mental dimensions. Persistent dyspnea is often reported and weakly correlated with PFTs alterations. Trial registration NCT04411459.

Even with encouraging recipient outcomes, transplantation using donation after circulatory death (DCD) is still limited. A major barrier to this type of transplantation is the consequences of warm ischemia on graft survival; however, preservation techniques may reduce the consequences of cardiac arrest and provide better organ conservation. Furthermore, DCD in trauma patients could further expand organ donation. We present five cases in which organs were retrieved and transplanted successfully using normothermic regional perfusion (NRP) in trauma patients. Prompt critical care support and surgical treatment allowed us to overcome the acute phase. Unfortunately, owing to the severity of their injuries, all of the donors died. However, the advanced and continuous organ-specific supportive treatment allowed the maintenance of general clinical stability and organ preservation. Consequently, it was possible to retrieve and transplant the donors’ organs. Death was ascertained in accordance with cardio-circulatory criteria, which was followed by NRP. We consider that DCD in trauma patients may represent an important source of organs.

Purpose The onset of the coronavirus disease 19 (COVID-19) pandemic in Italy induced a dramatic increase in the need for intensive care unit (ICU) beds for a large proportion of patients affected by COVID-19-related acute respiratory distress syndrome (ARDS). The aim of the present study was to describe the health-related quality of life (HRQoL) at 90 days after ICU discharge in a cohort of COVID-19 patients undergoing invasive mechanical ventilation and to compare it with an age and sex-matched sample from the general Italian and Finnish populations. Moreover, the possible associations between clinical, demographic, social factors, and HRQoL were investigated. Methods COVID-19 ARDS survivors from 16 participating ICUs were followed up until 90 days after ICU discharge and the HRQoL was evaluated with the 15D instrument. A parallel cohort of age and sex-matched Italian population from the same geographic areas was interviewed and a third group of matched Finnish population was extracted from the Finnish 2011 National Health survey. A linear regression analysis was performed to evaluate potential associations between the evaluated factors and HRQoL. Results 205 patients answered to the questionnaire. HRQoL of the COVID-19 ARDS patients was significantly lower than the matched populations in both physical and mental dimensions. Age, sex, number of comorbidities, ARDS class, duration of invasive mechanical ventilation, and occupational status were found to be significant determinants of the 90 days HRQoL. Clinical severity at ICU admission was poorly correlated to HRQoL. Conclusion COVID-19-related ARDS survivors at 90 days after ICU discharge present a significant reduction both on physical and psychological dimensions of HRQoL measured with the 15D instrument.

There is the urgent need to study the effects of immunomodulating agents as therapy for Covid-19. An observational, cohort, prospective study with 30 days of observation was carried out to assess clinical outcomes in 88 patients hospitalized for Covid-19 pneumonia and treated with canakinumab (300 mg sc). Median time from diagnosis of Covid-19 by viral swab to administration of canakinumab was 7.5 days (range 0–30, IQR 4–11). Median PaO2/FiO2 increased from 160 (range 53–409, IQR 122–210) at baseline to 237 (range 72–533, IQR 158–331) at day 7 after treatment with canakinumab (p 9/L, respectively, p p

Rhabdomyolysis is an uncommon complication of the coronavirus disease 2019 (COVID-19) infection. Previous reports have described its management and treatment in medical units, but have not discussed confirmatory tests or differential diagnosis. We report a case of a 58 year-old male patient, who was admitted for COVID-19 pneumonia and subsequently developed severe weakness, inability to move limbs, acute renal failure, significantly elevated myoglobin and creatinine kinase, and was diagnosed with rhabdomyolysis. Continuous renal replacement therapy, the treatment modality of choice over hyperhydration due to ongoing mechanical ventilation, was effective in resolving symptoms. No direct viral invasion of muscles was noted on biopsy. Here, we describe his symptoms, electromyography, and muscular biopsy results, and further discuss the possible differential diagnoses. Neuromuscular symptoms related to COVID-19 require careful clinical analysis. In addition, detailed reports of patients’ course of illness and diagnoses will assist in improving care for affected patients.

In recent years, many studies showed that the Trauma Mortality Probability Model (TMPM-ICD-9) had better calibration compared to other ICD-9-based models and to the ones based to the Abbreviated Injury Scale (AIS). The study aims to assess the validity of TMPM-ICD-9 in predicting injury severity in an Italian region and, through this model, to assess the performances of the Trauma Systems SIAT Romagna. Administrative data of trauma patients admitted in the Trauma System of SIAT Romagna, in Northern Italy, from 2014 to 2018 were obtained. The XISS, an indirect indicator of Injury Severity Score (ISS) and the TMPM-POD (Probability of Death) were calculated from ICD-9-CM codes. Only patients with XISS > 15 were included. Student t-test, Mann–Whitney test and Chi-square test were used for univariate analyses, while logistic regression for multivariate analyses. 3907 trauma patients with XISS > 15 were included. The Hub hospital (HUB) received 47.1% of these patients. Patients treated in HUB had higher TMPM-POD than in SPOKE + PST (mean TMPM-POD ± SD: HUB 0.093 ± 0.091, SPOKE + PST 0.082 ± 0.90, p

Introduction: despite the accumulating data on clinical and imaging features of COVID-19, its pathogenesis is still poorly understood. The majority of data regarding morphology and molecular changes regards post-mortem analysis; however, the value of performing lung biopsy on live patients more than autopsies on deceased patients is significantly high, as they may provide an insight into the complexity of the disease pathophysiology. Objectives: we examine the morphologic and molecular features of patients affected by COVID-19 who underwent lung biopsy at different times in the course of the disease: either at an earlier or at a later stage. Methods: comparative, multicenter, prospective, observational study. 24 patients were recruited. Lung samples were obtained by either cryobiopsy or TBB or SLB. Results: in most “early” phases of pneumonia the morphological changes did not match with typical DAD pattern; the exudative phase with jaline membranes and alveolar collapse were absent. Alveolar damage was patchy, varying from focal AECII hyperplasia to extensive nodular proliferation. The involvement of linear AECI was only partial; in advanced cases consistent remnants of normally looking AECI were present. A wide panel of immunohistochemical markers were just applied in samples (cytokeratin-7, cytokeratin 5/6, TTF1, CD34, Tubulin beta-3, alfa-SMA, CD163, CD14, CD20, CD138, CD3, CD4, CD8, T-bet, FoxP3, Gata-3, PD1, TCF1). Molecules involved in cell signaling, cell proliferation and activation were also investigated (beta-Catenin, phospho-STAT3, PDL-1, IDO, HLA-DR, CD25, gamma-fibrinogen).

Background: Multiple major health organisations recommend the use of extracorporeal membrane oxygenation (ECMO) support for COVID-19-related acute hypoxaemic respiratory failure. However, initial reports of ECMO use in patients with COVID-19 described very high mortality and there have been no large, international cohort studies of ECMO for COVID-19 reported to date. Methods: We used data from the Extracorporeal Life Support Organization (ELSO) Registry to characterise the epidemiology, hospital course, and outcomes of patients aged 16 years or older with confirmed COVID-19 who had ECMO support initiated between Jan 16 and May 1, 2020, at 213 hospitals in 36 countries. The primary outcome was in-hospital death in a time-to-event analysis assessed at 90 days after ECMO initiation. We applied a multivariable Cox model to examine whether patient and hospital factors were associated with in-hospital mortality. Findings: Data for 1035 patients with COVID-19 who received ECMO support were included in this study. Of these, 67 (6%) remained hospitalised, 311 (30%) were discharged home or to an acute rehabilitation centre, 101 (10%) were discharged to a long-term acute care centre or unspecified location, 176 (17%) were discharged to another hospital, and 380 (37%) died. The estimated cumulative incidence of in-hospital mortality 90 days after the initiation of ECMO was 37·4% (95% CI 34·4–40·4). Mortality was 39% (380 of 968) in patients with a final disposition of death or hospital discharge. The use of ECMO for circulatory support was independently associated with higher in-hospital mortality (hazard ratio 1·89, 95% CI 1·20–2·97). In the subset of patients with COVID-19 receiving respiratory (venovenous) ECMO and characterised as having acute respiratory distress syndrome, the estimated cumulative incidence of in-hospital mortality 90 days after the initiation of ECMO was 38·0% (95% CI 34·6–41·5). Interpretation: In patients with COVID-19 who received ECMO, both estimated mortality 90 days after ECMO and mortality in those with a final disposition of death or discharge were less than 40%. These data from 213 hospitals worldwide provide a generalisable estimate of ECMO mortality in the setting of COVID-19. Funding: None.

BackgroundPathogenesis of Coronavirus disease 2019 (Covid-19) is poorly understood. Most histologic studies come from post-mortem analysis, with existing data indicating that histologic features of acute respiratory distress syndrome are typically present in fatal cases. However, this observation may be misleading, due to confounding factors in pre-terminal disease, including injury resulting from prolonged mechanical ventilation. Ante-mortem lung biopsy may provide major pathogenetic insights, potentially providing a basis for novel treatment approaches.AimThis comparative, multicenter, prospective, observational study was planned to identify ante-mortem histological profile and immunohistochemical features of lung tissue in patients with Covid-19 in early and late phases of the disease, including markers of inflammatory cells and major pathways involved in the cytokine storm triggering.MethodsEnrolled patients underwent lung biopsy, according to the study protocol approved by local Ethical Committee, either within 15 days of the first symptoms appearing (early phase) or after >15 days (more advanced disease). Key exclusion criteria were excessive or uncorrectable bleeding risk and cardiovascular disease with heart failure. Lung samples were obtained by conventional transbronchial biopsy, trans-bronchial lung cryobiopsy or surgical lung biopsy.Results23 patients were enrolled: 12 patients underwent lung biopsy within 15 days and 11 patients more than 15 days after the onset of symptoms. Early biopsies were characterized by spots of patchy acute lung injury (ALI) with alveolar type II cells hyperplasia and significant vascular abnormalities (disordered angiogenesis with alveolar capillary hyperplasia, luminal enlargement and thickened walls of pulmonary venules, perivascular CD4-T-cell infiltration), with no hyaline membranes. In the later stages, the alveolar architecture appeared disrupted, with areas of organizing ALI, venular congestion and capillary thromboembolic microangiopathy. Striking phenotypic features were demonstrated in hyperplastic pneumocytes and endothelial cells, including the expression of phospho-STAT3 and molecules involved in immunoinhibitory signals (PD-L1 and IDO-1). Alveolar macrophages exhibited macrophage-related markers (CD68, CD11c, CD14) together with unusual markers, such as DC-Lamp/CD208, CD206, CD123/IL3AR.ConclusionA morphologically distinct “Covid pattern” was identified in the earlier stages of the disease, with prominent epithelial and endothelial cell abnormalities, that may be potentially reversible, differing strikingly from findings in classical diffuse alveolar damage. These observations may have major therapeutic implications, justifying studies of early interventions aimed at mitigating inflammatory organ injury.

Background Iron metabolism and immune response to SARS-CoV-2 have not been described yet in intensive care patients, although they are likely involved in Covid-19 pathogenesis. Methods We performed an observational study during the peak of pandemic in our intensive care unit, dosing D-dimer, C-reactive protein, troponin T, lactate dehydrogenase, ferritin, serum iron, transferrin, transferrin saturation, transferrin soluble receptor, lymphocyte count and NK, CD3, CD4, CD8 and B subgroups of 31 patients during the first 2 weeks of their ICU stay. Correlation with mortality and severity at the time of admission was tested with the Spearman coefficient and Mann–Whitney test. Trends over time were tested with the Kruskal–Wallis analysis. Results Lymphopenia is severe and constant, with a nadir on day 2 of ICU stay (median 0.555 109/L; interquartile range (IQR) 0.450 109/L); all lymphocytic subgroups are dramatically reduced in critically ill patients, while CD4/CD8 ratio remains normal. Neither ferritin nor lymphocyte count follows significant trends in ICU patients. Transferrin saturation is extremely reduced at ICU admission (median 9%; IQR 7%), then significantly increases at days 3 to 6 (median 33%, IQR 26.5%, p value 0.026). The same trend is observed with serum iron levels (median 25.5 μg/L, IQR 69 μg/L at admission; median 73 μg/L, IQR 56 μg/L on days 3 to 6) without reaching statistical significance. Hyperferritinemia is constant during intensive care stay: however, its dosage might be helpful in individuating patients developing haemophagocytic lymphohistiocytosis. D-dimer is elevated and progressively increases from admission (median 1319 μg/L; IQR 1285 μg/L) to days 3 to 6 (median 6820 μg/L; IQR 6619 μg/L), despite not reaching significant results. We describe trends of all the abovementioned parameters during ICU stay. Conclusions The description of iron metabolism and lymphocyte count in Covid-19 patients admitted to the intensive care unit provided with this paper might allow a wider understanding of SARS-CoV-2 pathophysiology.

Obese subjects with coronavirus disease 2019 (COVID-19) are at increased risk of requiring critical care (1), suggesting that excess body fat associates with greater disease severity. BMI does not discriminate between fat and lean body mass and poorly reflects fat distribution. Cardiometabolic diseases and increased systemic inflammation, two conditions associated with visceral adiposity, are also linked to COVID-19 severity and fatality (1,2). The aim of this study was to assess the relationship between abdominal fat distribution and COVID-19 severity. We hypothesized that excess visceral adipose tissue (VAT), as identified by an increased VAT to subcutaneous adipose tissue (SAT) ratio (VAT/SAT), is associated with COVID-19 severity, as defined by intensive care unit (ICU) admission. This was a single-center cohort study of 441 patients consecutively admitted to the Emergency Department (ED) of the Trauma Center Public Hospital Bufalini, Cesena, Italy, between 26 February and 6 April 2020 for a clinical suspicion of COVID-19. Of these patients, 144 had confirmed COVID-19 based on positive RT-PCR from a nasal and/or throat swab together with high-resolution computed tomography (HR-CT) findings suggestive of COVID-19 pneumonia. Of those, 61 (42%) were admitted to ICU (ICU-COVID-19 group). One-hundred thirty-six patients evaluated in the ED for clinical suspicion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) …

Background: Iron metabolism and immune response to SARS-CoV-2 have not been described yet in intensive care patients, although they are likely involved in Covid-19 pathogenesis. Little is known about clinical management of severe forms of Covid-19. Methods: we performed an observational study during the peak of pandemic in our intensive care unit, serially dosing D-dimer, C-reactive protein, Troponin T, Lactate Dehydrogenase, Ferritin, Serum iron, Transferrin, Transferrin Saturation, Transferrin Soluble Receptor, Lymphocyte count and NK, CD3, CD4, CD8, B subgroups of 31 patients during the first two weeks of their ICU stay. Correlation with mortality and severity at the time of admission was tested with Spearman coefficient and Mann-Whitney test. Trend over time were tested with Kruskall-Wallis analysis. Results: All patients show hyperferritinemia, and its dosage might be helpful in individuating patients developing hemophagocytic lymphohistiocytosis (we observed 1 case). Lymphopenia is severe and constant, with a nadir on day 2 of ICU stay (median 0.555 109/L; interquartile range (IQR) 0.450 109/L); all lymphocytic subgroups are dramatically reduced in critically ill patients, while CD4/CD8 ratio remains normal. Neither Ferritin nor lymphocyte count follow significant trends in ICU patients.

D-dimer is constantly elevated and progressively increases from admission (median 1319 µg/L; IQR 1285 µg/L) to day 3 to 6 (median 6820 µg/L; IQR 6619 µg/L), despite not reaching significant results. We describe trends of all the above mentioned parameters during ICU stay and provide a narrative review of our clinical experience about critical Covid-19 patients. D-dimer is constantly elevated in our ICU population and increases from admission to a maximum on day 3 to 6 of ICU stay (median 6820 µg/L; IQR 6619 µg/L) Conclusions: iron metabolism and lymphopenia are key clinical features of Covid-19 patients in the ICU setting and have been specifically described in this paper.

Background: Video-assisted thoracoscopic surgery (VATS) lobectomy has recently been adopted as the gold standard surgical option for the treatment of early stage non-small cell lung cancer. Enhanced recovery after surgery (ERAS) is being progressively adopted in thoracic surgery to improve the postoperative outcomes. Even if the benefits of ERAS are universally accepted, to date a standardized and uniform approach has not been described in the medical literature. The Italian VATS group has recently proposed to include in the VATS lobectomy database a structured protocol for ERAS. Methods: The ERAS section of the Italian VATS group is proposing a comprehensive ERAS protocol within the VATS lobectomy database, allowing the prospective collection of a dedicated set of data. Separate sections of the protocol are dedicated to different topics of ERAS. This study is specifically dedicated to the section of physiokinesis therapy. The medical literature will be extensively reviewed and a physiotherapy (PT) protocol of ERAS will be presented and discussed. A seta of structured clinical pathways will also be suggested for adoption in the VATS Group database. Discussion: Pre- and post-operative adoption of an ERAS protocol in patients undergoing VATS lobectomy may promote an improved post-operative course, a shorter hospital stay and an overall more comfortable patients’ experience. The mainstays of a physiokinesis therapy ERAS protocol are patients’ education, constant physical and respiratory therapy sessions, and adoption of adequate devices. Although many studies have investigated the usefulness of physical and respiratory physiokinesis therapy, a comprehensive ERAS protocol for VATS lobectomy patients has not yet been described. The proposed ERAS platform, adopted by the VATS Group database, will contribute to a prospective data collection and allow a scientific analysis of the results.

The outcome of patients with severe traumatic brain injury (TBI) and acute traumatic subdural hematoma (aSDH) admitted to the emergency room with bilaterally dilated, unreactive pupils (bilateral mydriasis) is notoriously poor. Of 2074 TBI patients consecutively admitted to our facility between 1997 and 2012, 115 had a first CT scan with aSDH, unreactive bilateral mydriasis, and a Glasgow Coma Score of 3 or 4. Sixty-two patients were unoperated and died within hours or a few days. The remaining 53 patients (2.5% of the 2074 consecutive patients) were scheduled for emergent evacuation of the aSDH. We compared three different dosages of mannitol to landmark different comprehensive levels of treatment: (1) a “basic” level of treatment characterized by a single conventional dose (18 to 36 g), (2) “reinforced” treatment landmarked by a single high dose (54 to 72 g), and (3) “aggressive” treatment landmarked by a single high dose (90 to 106 g). Doses above 36 g were administered intravenously over a period of 5 min. Of the 53 selected patients, 7 were aggressively managed (13.2%) and 24 (45.3%) received reinforced treatment. Rates of hyperventilation and barbiturate bolus administration were appropriately associated with increasing doses of mannitol. After adjustment for age, aggressive management was significantly associated with a lower risk of death and persistent vegetative state [adjusted OR 0.016 (95% 0.001–0.405)]. Patients surviving after aggressive management suffered more severe disability at 1 year. The study shows an association between reduced mortality and persistent vegetative state, albeit at the cost of increased long-term severe disability in survivors, and aggressive medical preoperative management of mydriatic patients with aSDH following TBI.

Gait recovery is one of the main goals of post-stroke rehabilitation and Robot-Assisted Gait Training (RAGT) has shown positive outcomes. However, there is a lack of studies in the literature comparing the effects of different devices. This paper aims to study the effects, in terms of clinical and gait outcomes, of treadmill-based and overground RAGT, compared to conventional gait training in stroke subjects. The results showed a significant improvement of clinical outcomes in both robotic treatments and in conventional therapy. The performance of locomotor tasks was clinically significant in the robotic groups only. The spatio-temporal gait parameters did not reveal any significant difference. Results suggest future multicentre studies on a larger number of subjects.

Subarachnoid hemorrhage (SAH) represents a medical emergency. Unfortunately, diagnosis can be delay due to cardiogenic abnormalities often associated with SAH. Cardiac manifestations are heterogeneous and common in patients with SAH. This phenomenon has not to be underestimated taking into account the devastating consequences of misdiagnosis and delay in the correct diagnosis and in a specific treatment, with serious and life-threatening consequences. We present a case report of an out of hospital ST elevation in a patient with Glasgow coma score of 6. He was primarily managed as an acute coronary syndrome case. However, coronary angiography was normal. After performing a computed tomography scan, the diagnosis of SAH was made.

Video-assisted thoracic surgery (VATS) is currently considered a ‘gold standard’ approach for pulmonary lobectomy in patients with early-stage lung cancer, displaying equal or superior results compared with an open traditional approach. In patients with limited pulmonary function, VATS lobectomy may reduce the impact of surgery and allow outcomes similar to patients with normal pulmonary function. The preliminary analysis of our initial, single center series of VATS lobectomy showed less complications and shorter postoperative length of stay compared with a historical series of open lobectomy patients. Patients with reduced predicted preoperative FEV1% (ppoFEV1%) who underwent VATS lobectomy had similar outcomes compared with patients with normal ppoFEV1, but longer postoperative length of stay.

The evidence suggests that antiplatelet agents (APA) slightly increase the risk of death and disease progression in patients with traumatic brain injury or spontaneous intracranial hemorrhage (ICH). There is little evidence that APA reversal with platelet (PLT) transfusion may improve the outcome. In this systematic review and meta-analysis, our goal was to evaluate the differences in mortality, severe disability, and hematoma expansion related to PLT transfusion. We retrieved randomized or cohort studies comparing adult patients on APA with traumatic brain injury or ICH who were treated with PLT or not. We calculated the standardized risk difference and 95% confidence interval. A random-effects model was applied to analyze the data. The heterogeneity of the retrieved trials was evaluated through the I2 statistic. Our review included 16 clinical trials. We observed a significant difference between the 2 groups only for hematoma expansion: risk difference was –0.10 (10%; 95% confidence interval, –0.14 to –0.05; P

Background Trauma victims could be an important source of organs. This article presents two cases of successful organ donation and transplant, after Maastricht category III cardiac death in patients with successfully repaired AAST grade V traumatic cardiac injuries. Case presentation The first donor was an adult patient with self-inflicted heart stab wound and non-survivable burn injury. The second one was an adult patient with blunt cardiac and abdominal trauma and an anoxic brain injury due to a car accident. The cardiac injury was promptly repaired in both patients. In the first case, adequate organ perfusion ante-mortem was achieved thanks to venoarterial extracorporeal membrane oxygenation and intensive care unit support. The above procedure allowed successful organ donation and transplantation even after Maastricht category III cardiac death. This is the first case reported where, for organ donation purposes, it was made necessary first thing to avoid the immediate death of the patient, due to a rare and frequently not survivable cardiac injury. The challenge of preserving organ perfusion, due to major burn injury effects, was faced afterwards. Conclusions The outcomes of these two cases suggest that a repaired heart injury should not be considered as an absolute contraindication to organ donation, even if it is associated with non-survivable major burns. Therefore, cardiac death could provide an opportunity for these kinds of patients to contribute to the pool of potential organ donors.

Robot-mediated therapies enhance the recovery of post-stroke patients with motor deficits. Repetitive and repeatable exercises are essential for rehabilitation following brain damage or other disorders that impact the central nervous system, as plasticity permits to reorganize its neural structure, fostering motor relearning. Despite the fact that so many studies claim the validity of robot-mediated therapy in post-stroke patient rehabilitation, it is still difficult to assess to what extent its adoption improves the efficacy of traditional therapy in daily life, and also because most of the studies involved planar robots. In this paper, we report the effects of a 20-session-rehabilitation project involving the Armeo Power robot, an assistive exoskeleton to perform 3D upper limb movements, in addition to conventional rehabilitation therapy, on 10 subacute stroke survivors. Patients were evaluated through clinical scales and a kinematic assessment of the upper limbs, both pre- and post-treatment. A set of indices based on the patients’ 3D kinematic data, gathered from an optoelectronic system, was calculated. Statistical analysis showed a remarkable difference in most parameters between pre- and post-treatment. Significant correlations between the kinematic parameters and clinical scales were found. Our findings suggest that 3D robot-mediated rehabilitation, in addition to conventional therapy, could represent an effective means for the recovery of upper limb disability. Kinematic assessment may represent a valid tool for objectively evaluating the efficacy of the rehabilitation treatment.

Background Wearable robots are people-oriented robots designed to be worn all day, thus helping in the daily activities. They can assist in walking, running, jumping higher or even lifting objects too heavy in normal conditions. Aim The aim of this report was to investigate the changes in gait pattern through 3D gait analysis of subjects with spinal cord injury (SCI) undergoing an adaptive training with a wearable exoskeletal device (ESD). The change in the quality of life was also investigate together with the possibility to wear these devices all day, to improve the mobility. Design Prospective quasi-experimental study, pre- and post-design. Setting Outpatient SCI patients. Population On a voluntary basis, eight SCI patients who had never used any ESD device were recruited. Methods Subjects underwent a three-dimensional gait analysis (3D GA) while wearing the ESD at baseline (inclusion) (T0) and after 20 sessions of training over an expected average of 5/6 weeks (T1). The secondary outcome measures were: Participant Satisfaction Questionnaire, 6-Minute Walking Test (6MWT), Borg Scale (the test was administered in indoor and outdoor conditions) and Timed Up-and-Go test (TUG). Spatiotemporal and kinematic parameters were assessed and their change from the beginning to the end of the training was the secondary outcome. Results No dropouts were recorded during the training and all subjects were able to terminate the protocol (compliant subjects: N.=8). After the training, all person showed some significant improvements for TUG, 6MWT and 10 MWT (Z=-2.521; P=0.008) and for the spatiotemporal and kinematics parameters. Conclusions This paper confirms that the adaptive training with ESD is safe and feasible in a heterogeneous sample of persons with SCI, especially in ameliorating the interaction between the patients and the device with an improvement of spatiotemporal and kinematics parameters. Clinical rehabilitation impact Since the training has been proven safe and the hypothesis that the subjects with spinal cord injury improving their performance over time and being able to adapt at the use of device in full autonomy at home during all the activities of the daily living has strengthened.

ObjectiveTo evaluate cross-sectional patient distribution and standardised 30-day mortality in the intensive care units (ICU) of an inclusive hub and spoke trauma system.SettingICUs of the Integrated System for Trauma Patient Care (SIAT) of Emilia-Romagna, an Italian region with a population of approximately 4.5 million.Participants5300 patients with an Injury Severity Score (ISS) >15 were admitted to the regional ICUs and recorded in the Regional Severe Trauma Registry between 2007 and 2012. Patients were classified by the Abbreviated Injury Score as follows: (1) traumatic brain injury (2) multiple injuriesand (3) extracranial lesions. The SIATs were divided into those with at least one neurosurgical level II trauma centre (TC) and those with a neurosurgical unit in the level I TC only.ResultsA higher proportion of patients (out of all SIAT patients) were admitted to the level I TC at the head of the SIAT with no additional neurosurgical facilities (1083/1472, 73.6%) compared with the level I TCs heading SIATs with neurosurgical level II TCs (1905/3815; 49.9%). A similar percentage of patients were admitted to level I TCs (1905/3815; 49.9%) and neurosurgical level II TCs (1702/3815, 44.6%) in the SIATs with neurosurgical level II TCs. Observed versus expected mortality (OE) was not statistically different among the three types of centre with a neurosurgical unit; however, the best mean OE values were observed in the level I TC in the SIAT with no neurosurgical unit.ConclusionThe Hub and Spoke concept was fully applied in the SIAT in which neurosurgical facilities were available in the level I TC only. The performance of this system suggests that competition among level I and level II TCs in the same Trauma System reduces performance in both. The density of neurosurgical centres must be considered by public health system governors before implementing trauma systems.

BACKGROUND In patients with traumatic brain injury (TBI), ventilator-associated pneumonia (VAP) is considered a dangerous complication, prompting early aggressive antibiotic treatment and prophylaxis. While this approach increases the selection of multidrug-resistant bacteria (MDR), its clinical benefit has not been demonstrated. METHODS One-year incidence of VAP in severe TBI patients (ICU stay >48 hours, with either Glasgow Coma Scale ≤8 or receiving intracranial pressure monitoring, or having undergone emergency surgery) and the prevalence of MDR among those who eventually developed it, were compared in two Italian intensive care units (ICUs) adopting different antibiotic approaches. Antibiotic use was guideline-driven and aggressive in the Pisa-based unit (165 eligible patients), and very conservative and coupled with non-pharmacological prevention measures in Cesena (262 patients). Data were also compared with those of 208 Italian ICUs participating in the same infection surveillance program. RESULTS Patient case mix and general care were similar in the two units. Overall antibiotic pressure was higher in Pisa (58.9% vs. 26.1% of beds occupied by patients receiving antibiotics, P

Summary This study aimed to gauge the opinions of patients' next of kin regarding transfer of patients from the specialist ‘Hub’ intensive care unit, to ‘Spoke’ intensive care units near home. We included 213 consecutive patients with severe trauma or severe acute neurological conditions admitted to the Hub intensive care unit over a 21-month period, who were repatriated to Spoke intensive care units for ongoing intensive care. One year after admission to the Hub intensive care unit, two thirds of patients' next of kin said they would have preferred patients to have been treated only in the Hub intensive care unit, and not repatriated. They perceived Hub intensive care unit care to be important, and would have preferred that their relatives be hospitalised there until intensive treatment was completed. The next of kin's preference was associated with severe acute neurological conditions (p ≤ 0.0001). Although centralised Hub & Spoke intensive care unit networks are appropriate to ensure specialised care, repatriation to local hospitals may not be appropriate for patients with severe neurological conditions.

Background Thymic epithelial tumors (TET) are the most frequent human primary mediastinal tumors in adults. A deep biological characterization of the processes at the basis of the transformed phenotype could strongly improve our understanding of the morphological and clinical heterogeneity of these diseases. MicroRNAs (miRNAs) are non-coding RNAs involved in post-transcriptional regulation and their altered expression accounts for the pathogenesis of several tumors. Objectives The aim of this study was to identify the miRNAs that are differentially expressed in tumor vs normal thymic tissues or among the different tumor histotypes and that could impact on the biology of TET. Materials and methods microRNAs expression profiling was performed by microarray analysis of formalin-fixed paraffin embedded (FFPE) tissue from 54 thymic tumor samples and 12 normal counterparts, derived from two patient cohorts. Results and conclusion We identified groups of miRNAs differentially expressed between: (i) TET and normal thymic tissues, (ii) thymomas and thymic carcinomas, (iii) histotype groups. Moreover, we identified putative molecular pathways targeted by these differentially expressed miRNAs that could be involved in thymic carcinogenesis and in the maintenance and spreading of this tumor.

Introduction: Resuscitative endovascular balloon occlusion of the aorta has been used in various clinical settings to elevate blood pressure in the setting of shock, even if the evidence base is weak with no clear indications. Case presentation: We report a case of traumatic hemorrhagic shock in which this technique was used in an unusual manner, treating obvious arterial abdominal bleeding associated with suspected pelvic arterial bleeding, in a Trauma Center where hybrid angiographic-surgical suite is not available. A 35-year-old man was involved in a traffic accident within 2 trucks. He was transported to the Major Trauma Center of an Integrated Trauma System where emergent laparotomy confirmed massive hepatic rupture and a bleeding control was obtained by large abdominal packing. Trauma team decided to considerate Resuscitative Endovascular Balloon Occlusion of the Aorta, positioning a deflated balloon in zone III to eventually manage a pelvic arterial hemorrhage, while performing Bogota Bag. Suddenly a new abdominal arterial bleeding was noted through Bogota Bag. Because Pringle maneuver was considered too difficult in this case because of liver hilum injury, the balloon was moved cranially with the aim to reach zone I. Introducer sheath displacement occurred at this time, and the balloon was then only partially inflated in zone II, usually considered too dangerous, and immediately the target systolic blood pressure of 90 mmHg was obtained. Transfer the patient into interventional radiology suite was then feasible and embolization of active bleeding by right hepatic artery and superior mesenteric artery branch, missed during first laparotomy, were performed. Balloon was definitely deflated after 50 minutes. The patient was discharged by the hospital 113 days later, fully recovered with long lasting motor rehabilitation program. Discussion: Partial zone II Resuscitative Endovascular Balloon Occlusion of the Aorta in this particular case allowed overcoming procedural mistakes without major complications and with good clinical outcome. Conclusion: Judicious manage of REBOA inflation time and amount, together with multidisciplinary contemporary damage control strategy with clear and effective team leading, is the key to effectively resuscitate multiple trauma shocked patients.

Inflammatory myofibroblastic tumors (IMTs) are rare neoplasms that can involve the airway. Recent studies have shown their malignant behavior with local recurrence and potential metastatic spread; half of the cases are associated with anaplastic lymphoma kinase gene rearrangement. Complete surgical resection is recommended, when feasible. We present a case of a 26-year-old woman admitted to our institution with severe respiratory failure; she was affected with primary IMT of the trachea and underwent complete surgical resection.

Spinal cord injury (SCI) is a severe neurological disorder associated not only with ongoing medical complications but also with a significant loss of mobility and participation. The introduction of robotic technologies to recover lower limb function has been greatly employed in the rehabilitative practice. The aim of this preliminary report were to evaluate the efficacy, the feasibility and the changes in the mobility and in the de-adaptations of a new rehabilitative protocol for EKSO™ a robotic exoskeleton device in subjects with SCI disease with an impairment of lower limbs assessed by gait analysis and clinical outcomes. This is a pilot single case experimental A-B (pre-post) design study. Three cognitively intact voluntary participants with SCI and gait disorders were admitted. All subjects were submitted to a training program of robot walking sessions for 45 min daily over 20 sessions. The spatiotemporal parameters at the beginning (T0) and at the end of treatment (T1) were recorded. Other clinical assessments (6 min walking test and Timed Up and Go test) were acquired at T0 and T1. Robot training were feasible and acceptable and all participants completed the training sessions. All subjects showed improvements in gait spatiotemporal indexes (Mean velocity, Cadence, Step length and Step width) and in 6 min Walking Test (T0 versus T1). Robot training is a feasible form of rehabilitation for people with SCI. Further investigation regarding long term effectiveness of robot training in time is necessary.

Thymic epithelial cells give rise to both thymoma and thymic carcinoma. A crucial advance in thymic epithelial tumors (TET) management may derive from the identification of novel molecular biomarkers able to improve diagnosis, prognosis and treatment planning.In a previous study, we identified microRNAs that were differentially expressed in tumor vs normal thymic tissues. Among the microRNAs resulted up-regulated in TET tissues, we evaluated miR-21-5p, miR-148a-3p, miR-141-3p, miR-34b-5p, miR-34c-5p, miR-455-5p as blood plasma circulating non-invasive biomarkers for TET management.We firstly report that the expression levels of specific onco-miRNAs, that we found upregulated in the blood plasma collected from TET patients at surgery, resulted significantly reduced in follow-up samples.This pilot study suggests that circulating miR-21-5p and miR-148a-3p could represent novel non-invasive biomarkers to evaluate the efficacy of therapy and the prognosis of TET.

Introduction Hemorrhage is the principal cause of death in the first few hours following severe injury. Coagulopathy is a frequent complication of critical bleeding. A network of Italian trauma centers recently developed a protocol to prevent and treat trauma-induced coagulopathy. A pre-post cohort multicenter study was conducted to assess the impact of the early coagulation support (ECS) protocol on blood products consumption, mortality and treatment costs. Methods We prospectively collected data from all severely injured patients (Injury Severity Score (ISS) >15) admitted to two trauma centers in 2013 and compared these findings with the data for 2011. Patients transfused with at least 3 units of packed red blood cells (PRBCs) within 24 hours of an accident were included in the study. In 2011, patients with significant hemorrhaging were treated with early administration of plasma with the aim of achieving a high (≥1:2) plasma-to-PRBC ratio. In 2013, the ECS protocol was the treatment strategy. Outcome data, blood product consumption and treatment costs were compared between the two periods. Results The two groups were well matched for demographics, injury severity (ISS: 32.9 in 2011 versus 33.6 in 2013) and clinical and laboratory data on admission. In 2013, a 40% overall reduction in PRBCs was observed, together with a 65% reduction in plasma and a 52% reduction in platelets. Patients in the ECS group received fewer blood products: 6.51 units of PRBCs versus 8.14 units. Plasma transfusions decreased from 8.98 units to 4.21 units (P P Conclusions The introduction of the ECS protocol in two Italian trauma centers was associated with a marked reduction in blood product consumption, reaching statistical significance for plasma and platelets, and with a non-significant trend toward a reduction in early and 28-day mortality. The overall costs for transfusion and coagulation support (including point-of-care tests) decreased by 23% between 2011 and 2013.

Background: New bronchoscopic techniques for end-stage emphysema treatment are nowadays available; the presence of interlobar collateral ventilation (CV) and interlobar lung fissures (ILF) is crucial for patient selection. Objectives: Assessment of these variables has been reported previously, but it has never been anatomically validated in vivo. This is the purpose of our study. Methods: Twenty-one patients undergoing lung resection for lung cancer were prospectively enrolled in this study. At operation, CV was assessed by the Chartis® catheter system. ILF completeness at high-resolution computed tomography (HRCT) was retrospectively reviewed. The ILF status at HRCT and at surgery was compared; furthermore, the relationship between CV and ILF status was assessed. Results: At HRCT, ILF were incomplete in 18 cases; at catheter evaluation, CV was present in 11 cases; 15 patients had incomplete ILF at operation. HRCT specificity, sensitivity and accuracy were 33, 93 and 76% compared with ILF status at surgery. HRCT accuracy was 90% on the right and 63% on the left. We demonstrated a high grade of probability of CV presence and incomplete ILF at surgery (odds ratio = 10.0). Conclusions: There is a correlation between ILF status and CV. Both catheter evaluation of CV and HRCT assessment of ILF show some limitations. However, the cumulative information provided by these techniques allows to reliably assess the anatomical ILF status.

Lung transplantation (OLT) is a viable option for end-stage pulmonary diseases in selected patients with satisfactory long-term results. However, the paucity of available donors engenders a prolonged stay on the waiting list with progressive decline of lung function. In cases of sudden respiratory failure, admission to an intensive care unit with institution of extracorporeal membrane oxygenation (ECMO) may be an option while a waiting an emergency OLT. In 12 OLT candidates we started ECMO because of acute decline of lung function. Eleven patients had cystic fibrosis and the other subject, histiocytosis X. In 7 patients bilateral OLT was performed after a mean waiting time of 6 days from ECMO institution; 5 patients died on ECMO at a mean time of 11.6 days. After OLT 2 patients required reoperation for hemothorax; renal failure and acute leg ischemia occurred in 2 patients. The mean weaning time from ECMO after OLT was 2.14 days. No patient died in the perioperative period and 1-year survival was 85.7%. ECMO represents a valid option as a bridge to urgent OLT for selected candidates.
