Early Cold Stored Platelet Transfusion Following Severe Injury: A Randomized Clinical Trial.

OBJECTIVE: To determine the feasibility, efficacy, and safety of early cold stored platelet transfusion compared with standard care resuscitation in patients with hemorrhagic shock. BACKGROUND: Data demonstrating the safety and efficacy of early cold stored platelet transfusion are lacking following severe injury. METHODS: A phase 2, multicenter, randomized, open label, clinical trial was performed at 5 US trauma centers. Injured patients at risk of large volume blood transfusion and the need for hemorrhage control procedures were enrolled and randomized. The intervention was the early transfusion of a single apheresis cold stored platelet unit, stored for up to 14 days versus standard care resuscitation. The primary outcome was feasibility and the principal clinical outcome for efficacy and safety was 24-hour mortality. RESULTS: Mortality at 24 hours was 5.9% in patients who were randomized to early cold stored platelet transfusion compared with 10.2% in the standard care arm (difference, -4.3%; 95% CI, -12.8% to 3.5%; P =0.26). No significant differences were found for any of the prespecified ancillary outcomes. Rates of arterial and/or venous thromboembolism and adverse events did not differ across treatment groups. CONCLUSIONS AND RELEVANCE: In severely injured patients, early cold stored platelet transfusion is feasible, safe and did not result in a significant lower rate of 24-hour mortality. Early cold stored platelet transfusion did not result in a higher incidence of arterial and/or venous thrombotic complications or adverse events. The storage age of the cold stored platelet product was not associated with significant outcome differences. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04667468.

Impact of breast surgical procedure on survival in BRCA mutated patients with invasive breast cancer: Mastectomy versus conservative treatment.

INTRODUCTION: Patients with BRCA1/2 mutations have a higher risk of developing breast cancer compared to the wild-type population. For patients with a BRCA mutation, there are no specific recommendations for surgical management. The aim of this study was therefore to retrospectively investigate overall survival (OS) and recurrence-free survival (RFS) of BRCA mutated patients with localized invasive breast cancer, by comparing conservative surgery versus mastectomy. METHODS: This study was based on data from the Côte d'Or breast and gynecological cancer registry. Data from patients with a constitutional BRCA1/2 mutation who presented with invasive breast cancer were collected retrospectively from 1998 to 2018. The Kaplan-Meier method was used to describe RFS and OS. RESULTS: A total of 104 patients were included in the analysis, of whom 69 had conservative surgery and 35 underwent mastectomy. Regarding survival, there was no significant difference in OS (HR =1.49; 95 % confidence interval (CI) [0.76-2.93], p = 0.25). Similarly, there was no significant difference in RFS (HR =1.40; 95 % CI [0.81-2.40], p = 0.22), survival without homolateral recurrence (HR =0.88; 95 % CI [0.30-2.61], p = 0.89), without contralateral recurrence (HR =1.50; 95 % CI [0.55-4.09], p = 0.42), or without distant metastatic recurrence (HR =1.42, 95 % CI [0.69-2.90], p = 0.33). CONCLUSION: In invasive breast cancer in a patient with a germline BRCA1/2 mutation, conservative surgery, when possible, appears to be a feasible option over total mastectomy, with no difference in overall survival. However, the patient should be informed of the aggressive nature of recurrence in this population requiring chemotherapy in most cases.

[Updated indications and techniques for immediate breast reconstruction, particularly in the case of adjuvant radiotherapy]. / Actualisation des indications et techniques de reconstruction mammaire immédiate, notamment en cas de radiothérapie adjuvante.

In 2023, 62,000 patients were diagnosed with breast cancer in France. Every year, 22,000 mastectomies are performed. Breast reconstruction (BR) should be an integral part of breast cancer management. Yet the MR rate in France is only 28% within 3 years of mastectomy, of which 14% are immediate breast reconstruction (IBR). The number of contraindications to RMI has steadily declined over the last few decades, although some of them remain definitive, such as inflammatory cancer (T4d). Today, many specialists involved in the management of breast cancer consider that IBR can be proposed in cases where adjuvant chemotherapy and/or radiotherapy is indicated, if it is not expected to delay carcinological management. The surgical team must then inform the patient of all available BR techniques. If a team does not offer a particular technique, the patient should be referred to a center that does. In all cases, the proposal for curative and reparative treatment should be the subject of a multidisciplinary discussion involving, in particular, a surgeon, a radiotherapist and a medical oncologist. When adjuvant radiotherapy is indicated, the patient must be informed of the increased risk of complications and deterioration of the aesthetic result. In this indication, RMI by prosthesis is a validated technique. However, if the patient has a history of radiotherapy, autologous techniques should be preferred. In a context of shared decision-making, the choice of whether or not to undergo MR and the type of technique must ultimately be made by the patient, in agreement with the multidisciplinary team.

Impact of the withdrawal of macrotextured implant on reconstruction practices.

INTRODUCTION: On 22 November 2018, the French Society for Plastic, Reconstructive and Aesthetic Surgery recommended that Allergan® macrotextured breast implants be recalled, a decision endorsed by the French national health products safety agency (ANSM) on 2nd April 2019. At the Georges-François Leclerc Cancer Center (CGFL) in Dijon, we decided to stop using macrotextured implants as of November 2018 in favor of smooth implants. The purpose of this study is to evaluate the impact of the recall of macrotextured implants on breast reconstruction surgical practices and their complications. METHODS: This is a single-centre, retrospective study performed at the CGFL in Dijon, France. Reconstruction techniques and complications were compared between two periods, i.e. before the recall of macrotextured breast implants (period 1: 1st September 2017-November 22, 2018) and after the recall (period 2: 23 November 2018-31st March 2020). All patients who underwent breast reconstruction for the first time were included. RESULTS: Data were collected from 168 reconstructions in period 2, and 159 in period 2. The rate of use of breast implants during reconstructions decreased significantly in period 2 (53.6% vs. 23.9%; P<0.001). The rate of autologous reconstructions increased significantly for muscle sparing latissimus dorsi (2.4% vs. 12.6%; P<0.001) and exclusive fat grafting (9.5% vs. 21.5%; P<0.01). Clavien-Dindo Stage IIIb complications decreased in period 2 (10% vs. 18.4%; P=0.04). CONCLUSION: Since the recall of macrotextured breast implants, the reconstruction rate has decreased in our centre in favor of autologous techniques with lower complication rates.

Reduction in transfer of micro-organisms between patients and staff using short-sleeved gowns and hand/arm hygiene in intensive care during the COVID-19 pandemic: A simulation-based randomised trial.

Background: Current personal protective equipment (PPE) practices in UK intensive care units involve "sessional" use of long-sleeved gowns, risking nosocomial infection transmitted via gown sleeves. Data from the first wave of the COVID19 pandemic demonstrated that these changes in infection prevention and control protocols were associated with an increase in healthcare associated bloodstream infections. We therefore explored the use of a protocol using short-sleeved gowns with hand and arm hygiene to reduce this risk. Methods: ICU staff were trained in wearing short-sleeved gowns and using a specific hand and arm washing technique between patients (experimental protocol). They then underwent simulation training, performing COVID-19 intubation and proning tasks using either experimental protocol or the standard (long-sleeved) control protocol. Fluorescent powder was used to simulate microbial contamination, detected using photographs under ultraviolet light. Teams were randomised to use control or experimental PPE first. During the simulation, staff were questioned on their feelings about personal safety, comfort and patient safety. Results: Sixty-eight staff and 17 proning volunteers were studied. Experimental PPE completely prevented staff contamination during COVID-19 intubation, whereas this occurred in 30/67 staff wearing control PPE (p = .003, McNemar). Proning volunteers were contaminated by staff in 15/17 control sessions and in 1/17 with experimental PPE (p = .023 McNemar). Staff comfort was superior with experimental PPE (p< .001, Wilcoxon). Their personal safety perception was initially higher with control PPE, but changed towards neutrality during sessions (p < .001 start, 0.068 end). Their impressions of patient safety were initially similar (p = .87), but finished strongly in favour of experimental PPE (p < .001). Conclusions: Short-sleeved gowns with hand and forearm cleansing appear superior to sessional long-sleeved gowns in preventing cross-contamination between staff and patients.

Randomized Controlled Trial of Surgical Rib Fixation to Nonoperative Management in Severe Chest Wall Injury.

OBJECTIVE: To compare the effectiveness of surgical stabilization of rib fractures (SSRFs) to nonoperative management in severe chest wall injury. BACKGROUND: SSRF has been shown to improve outcomes in patients with clinical flail chest and respiratory failure. However, the effect of SSRF outcomes in severe chest wall injuries without clinical flail chest is unknown. METHODS: Randomized controlled trial comparing SSRF to nonoperative management in severe chest wall injury, defined as: (1) a radiographic flail segment without clinical flail or (2) ≥5 consecutive rib fractures or (3) any rib fracture with bicortical displacement. Randomization was stratified by the unit of admission as a proxy for injury severity. Primary outcome was hospital length of stay (LOS). Secondary outcomes included intensive care unit (ICU) LOS, ventilator days, opioid exposure, mortality, and incidences of pneumonia and tracheostomy. Quality of life at 1, 3, and 6 months was measured using the EQ-5D-5L survey. RESULTS: Eighty-four patients were randomized in an intention-to-treat analysis (usual care = 42, SSRF = 42). Baseline characteristics were similar between groups. The numbers of total fractures, displaced fractures, and segmental fractures per patient were also similar, as were the incidences of displaced fractures and radiographic flail segments. Hospital LOS was greater in the SSRF group. ICU LOS and ventilator days were similar. After adjusting for the stratification variable, hospital LOS remained greater in the SSRF group (RR: 1.48, 95% CI: 1.17-1.88). ICU LOS (RR: 1.65, 95% CI: 0.94-2.92) and ventilator days (RR: 1.49, 95% CI: 0.61--3.69) remained similar. Subgroup analysis showed that patients with displaced fractures were more likely to have LOS outcomes similar to their usual care counterparts. At 1 month, SSRF patients had greater impairment in mobility [3 (2-3) vs 2 (1-2), P = 0.012] and self-care [2 (1-2) vs 2 (2-3), P = 0.034] dimensions of the EQ-5D-5L. CONCLUSIONS: In severe chest wall injury, even in the absence of clinical flail chest, the majority of patients still reported moderate to extreme pain and impairment of usual physical activity at one month. SSRF increased hospital LOS and did not provide any quality of life benefit for up to 6 months.

Evaluation of the management of intracystic papillary carcinoma.

INTRODUCTION: Intracystic papillary carcinoma is defined as papillary carcinoma located in a dilated or cystic duct. There is no consensus regarding the management of this lesion. The aim of our study is to evaluate the frequency of associated invasive lesions and the need to perform an axillary staging during surgery. MATERIAL AND METHODS: This is a retrospective study concerning intracystic papillary carcinomas diagnosed at the Georges-François Leclerc Cancer Center between January 2010 and December 2021. Inclusion criteria were an age superior to 18 years and a histologic diagnosis confirmed at biopsy. RESULTS: Fifty-nine patients were included in this study. All but one patient underwent surgery: 39 patients (67.2%) underwent lumpectomy, and 18 patients (31.1%) underwent total mastectomy. An axillary staging was performed in 51 patients (86.4%). On final histologic analysis, 31 patients (52.5%) had pure intracystic papillary carcinoma and/or associated with in situ and 27 patients (45.8%) had invasive and/or microinvasive lesions. After univariate analysis, the only variable significantly associated with the presence of invasive lesions on final histologic analysis was the palpation of the lesion with a P-value of 0.09. DISCUSSION: Through this study, it appears necessary to discuss the realization of an axillary staging by conducting an axillary sentinel node procedure because of the high frequency of invasive lesions associated with intracystic papillary carcinoma.

Axillary pathologic response after neoadjuvant chemotherapy and surgery according to breast cancers subtypes and survival impact.

PURPOSE: To retrospectively assess the rate of pathologic complete response in the axilla according to breast cancer biologic subtypes, and to study the impact of nodal response on survival. METHODS: Inclusion criteria were all T-stage breast cancers with initial lymph node involvement, non-metastatic, treated with neoadjuvant chemotherapy followed by surgery with axillary lymph node dissection, managed at the George-François Leclerc Cancer Center in Dijon, France, between 2000 and 2018. RESULTS: Among 437 patients included, the rate of complete nodal response rate varied according to tumor subtypes: 69.4% in Hormone Receptors (HR)-/HER2-positive, 47.4% in HR-/HER2-negative, 46.7% in HR+/HER2-positive, 8.5% in HR+/HER2-negative. By multivariate analysis, the factors significantly associated with complete nodal response were HER2-positive profile (OR 4.48 [2.14-9.65], P<0.001 if HR+; OR 8.02 [3.54-18.74], P<0.001 if HR-), triple negative tumors (OR 3.01 [1.40-6.58], P=0.005), SBRIII grade (OR 6.85 [2.28-29.58], P=0.002) and breast complete response (OR 18.69 [9.67-38.53], P<0.001). Five-year recurrence rates were 15.7% in ypN0, 23% in ypN1, 41.2% in ypN2, 50% in ypN3 patients (P<0.001). Five-year overall survival rates were 92.2% in ypN0, 85.7% in ypN1, 72.2% in ypN2, 65.4% in ypN3 patients (P<0.001). CONCLUSION: The impact of nodal response on survival was significant. Pathologic complete response in the axilla appears to be a good surrogate marker of long-term outcome in patients treated for these cancers.

Impact of therapeutic strategy on disease-free and overall survival of early-stage cervical cancer: Surgery alone versus preoperative radiation.

BACKGROUND AND OBJECTIVES: There is no international consensus for management of early-stage cervical cancer (ESCC). This study aimed to retrospectively investigate disease-free survival (DFS) and overall survival (OS) in patients with ESCC according to the therapeutic strategy used, surgery alone versus preoperative radiation following by surgery. METHODS: Data were retrospectively collected from 1998 to 2015 using the Gynecological Cancer Registry of the Côte d'Or. The inclusion criteria were FIGO 2018 ≤ IB2; squamous cell carcinoma, adenocarcinoma or adenosquamous type. Survival curves were compared using the log-rank test. RESULTS: One hundred twenty-six patients were included. Median survival was 90 months. There was no significant difference in DFS (HR = 0.91, 95%CI [0.32-2.53], p = 0.858) or in OS between surgery alone versus preoperative radiation following by surgery (HR = 0.97, 95%CI [0.31-2.99], p = 0.961). In the subgroup of patients with stage ≥IB1, there was no significant difference in DFS (HR = 3.26, p = 0.2) or in OS (HR = 3.87, p = 0.2). CONCLUSION: Our study did not identify any difference in survival according to the treatment strategy. Preoperative radiation following by surgery can be an alternative to surgery alone for ESCC.

Building a Covid-19 secure intensive care unit: A human-centred design approach.

Background: The Covid-19 pandemic has highlighted weaknesses in the National Health Service critical care provision including both capacity and infrastructure. Traditionally, healthcare workspaces have failed to fully incorporate Human-Centred Design principles resulting in environments that negatively affect the efficacy of task completion, patient safety and staff wellbeing. In the summer of 2020, we received funds for the urgent construction of a Covid-19 secure critical care facility. The aim of this project was to design a pandemic resilient facility centred around both staff and patient requirements and safety, within the available footprint. Methods: We developed a simulation exercise, underpinned by Human-Centred Design principles, to evaluate intensive care designs through Build Mapping, Tasks Analysis and Qualitative data. Build Mapping involved taping out sections of the design and mocking up with equipment. Task Analysis and qualitative data were collected following task completion. Results: 56 participants completed the build simulation exercise generating 141 design suggestions (69 task related, 56 patient and relative related, 16 staff related). Suggestions translated to 18 multilevel design improvements; five significant structural changes (Macro level) including wall moves and lift size change. Minor improvements were made at a Meso and Micro design level. Critical care design drivers identified included functional drivers (visibility, Covid-19 secure environment, workflow, and task efficiency) and behavioural drivers (learning and development, light, humanising intensive care and design consistency). Conclusion: Success of clinical tasks, infection control, patient safety and staff/patient wellbeing are highly dependent on clinical environments. Primarily, we have improved clinical design by focusing on user requirements. Secondly, we developed a replicable approach to exploring healthcare build plans revealing significant design changes, that may have only been identified once built.

Association of Changes in Antithrombin Activity Over Time With Responsiveness to Enoxaparin Prophylaxis and Risk of Trauma-Related Venous Thromboembolism.

Importance: Venous thromboembolism (VTE) affects 2% to 20% of recovering trauma patients, despite aggressive prophylaxis with enoxaparin. Antithrombin is a primary circulating anticoagulant and crucial component of enoxaparin thromboprophylaxis. Approximately 20% of trauma patients present with antithrombin deficiency (antithrombin activity <80%). Objective: To examine time-dependent changes in antithrombin activity, responsiveness to enoxaparin, as measured by anti-factor Xa (anti-FXa) levels, and incidence of VTE after severe trauma and to assess the association of ex vivo antithrombin supplementation with patients' sensitivity to enoxaparin prophylaxis. Design, Setting, and Participants: This single-center, prospective cohort study was performed at a level 1 trauma center between January 7, 2019, and February 28, 2020. Adult trauma patients admitted to the trauma service at high risk for VTE, based on injury pattern and severity, were screened and enrolled. Patients who were older than 70 years, were pregnant, had a known immunologic or coagulation disorder, or were receiving prehospital anticoagulants were excluded. Exposures: Blood samples were collected on emergency department arrival and daily for the first 8 days of hospitalization. Main Outcomes and Measures: Patients' antithrombin activity and anti-FXa levels were measured by a coagulation analyzer, and thrombin generation was measured by calibrated automated thrombography. Responsiveness to enoxaparin was assessed by measuring anti-FXa levels 4 to 6 hours after the first daily enoxaparin dose and compared between patients who developed VTE and who did not. In addition, the associations of ex vivo supplementation of antithrombin with plasma anti-FXa levels were assessed. Results: Among 150 patients enrolled (median [IQR] age, 35 [27-53] years; 37 [24.7%] female and 113 [75.3%] male; 5 [3.3%] Asian, 32 [21.3%] Black, and 113 [75.3%] White; and 51 [34.0%] of Hispanic ethnicity), 28 (18.7%) developed VTE. Patients with VTE had significantly lower antithrombin activity on admission compared with patients without VTE (median [IQR], 91% [79%-104%] vs 100% [88%-112%]; P = .04), as well as lower antithrombin activity on hospital days 5 (median (IQR), 90% [83%-99%] vs 114% [99%-130%]; P = .011), 6 (median [IQR], 97% [81%-109%] vs 123% [104%-134%]; P = .003), 7 (median [IQR], 82% [74%-89%] vs 123% [110%-140%]; P < .001), and 8 (median [IQR], 99% [85%-100%] vs 123% [109%-146%]; P = .011). Anti-FXa levels were significantly lower in patients with VTE vs those without VTE at hospital day 4 (median [IQR], 0.10 [0.05-0.14] IU/mL vs 0.18 [0.13-0.23] IU/mL; P = .006), day 6 (median [IQR], 0.12 [0.08-0.14] IU/mL vs 0.22 [0.13-0.28] IU/mL; P = .02), and day 7 (median [IQR], 0.11 [0.08-0.12] IU/mL vs 0.21 [0.13, 0.28] IU/mL; P = .002). Multivariable analyses found that for every 10% decrease in antithrombin activity during the first 3 days, the risk of VTE increased 1.5-fold. Conclusions and Relevance: The results of this cohort study suggest that after severe trauma, antithrombin deficiency is common and contributes to enoxaparin resistance and VTE. Interventional studies are necessary to determine the efficacy of antithrombin supplementation in the reduction of VTE incidence.

Omitting axillary lymph node dissection after positive sentinel lymph node in the post-Z0011 era: Compliance with NCCN and ASCO clinical guidelines and Z0011 criteria in a large prospective cohort.

PURPOSE: In the ACOSOG Z0011 trial, patients with primary breast cancer and 1-2 tumor-involved sentinel lymph nodes (SLNs) undergoing breast-conserving surgery had no oncological outcome benefit after axillary lymph node dissection (ALND), despite a relevant rate of non-SLN metastases of 27%. According to the St Gallen expert consensus, and NCCN and ASCO clinical guidelines, ALND may be avoided in patients who meet all ACOSOG Z0011 inclusion criteria. This recommendation can also be extended to patients undergoing mastectomy, with 1 or 2 positive SLNs and an indication for chest wall radiation, in whom axillary radiotherapy can be proposed as an alternative to completion ALND. The aim of this study was to assess non-compliance with the NCCN and ASCO clinical guidelines and Z0011 criteria, namely the rate of performance of completion ALND when it was not recommended, and the rate of failure to perform completion ALND when recommended. METHODS: Data were prospectively analysed from T1-2 N0 breast cancer patients undergoing an SLN procedure and treated at the Georges-François Leclerc Cancer Center between November 2015 and May 2017. Factors associated with non-compliance treatment decisions were identified using logistic regression. RESULTS: Among 563 patients included, 122 (21.7%) had at least one positive SLN. ALND was not recommended for 76 patients (62.3%), and was recommended in 46 patients (37.7%). The rate of non-compliant treatment was 32% (39/122) overall: ALND was performed despite not being recommended in 16/76 patients (21.1%) and was not performed in 50% of patients in whom it was recommended (23/46). By multivariate analyses, lymphovascular invasion ((Odds Ratio (OR)=6.1; 95% confidence interval (CI): 1.4-26.7; P=0.02)) and only one SLN removed (OR=9.1; 95%CI: 2.2-33.3; P=0.002) were associated with performance of completion ALND when not recommended. Conversely, >1 SLN removed (OR=5.1; 95%CI: 1.2-22.2; P=0.03) was associated with the failure to perform completion ALND when recommended. CONCLUSION: Almost one third of patients with invasive breast cancer receive treatment that is not in compliance with recommendations regarding completion ALND.

NETosis Markers in Pregnancy: Effects Differ According to Histone Subtypes.

NETosis is an innate immune response occurring after infection or inflammation: activated neutrophils expel decondensed DNA in complex with histones into the extracellular environment in a controlled manner. It activates coagulation and fuels the risk of thrombosis. Human pregnancy is associated with a mild proinflammatory state characterized by circulatory neutrophil activation which is further increased in complicated pregnancies, placenta-mediated complications being associated with an increased thrombotic risk. This aberrant activation leads to an increased release of nucleosomes in the blood flow. The aim of our study was to initially quantify nucleosome-bound histones in normal pregnancy and in placenta-mediated complication counterpart. We analyzed the role of histones on extravillous trophoblast function. Circulating nucleosome-bound histones H3 (Nu.QH3.1, Nu.QH3PanCit, Nu.QH3K27me3) and H4 (Nu.QH4K16Ac) were increased in complicated pregnancies. In vitro using the extravillous cell line HTR-8/SVNeo, we observed that free recombinant H2B, H3, and H4 inhibited migration in wound healing assay, but only H3 also blocked invasion in Matrigel-coated Transwell experiments. H3 and H4 also induced apoptosis, whereas H2B did not. Finally, the negative effects of H3 on invasion and apoptosis could be restored with enoxaparin, a low-molecular-weight heparin (LMWH), but not with aspirin. Different circulating nucleosome-bound histones are increased in complicated pregnancy and this would affect migration, invasion, and induce apoptosis of extravillous trophoblasts. Histones might be part of the link between the risk of thrombosis and pregnancy complications, with an effect of LMWH on both.

Effect of Out-of-Hospital Tranexamic Acid vs Placebo on 6-Month Functional Neurologic Outcomes in Patients With Moderate or Severe Traumatic Brain Injury.

Importance: Traumatic brain injury (TBI) is the leading cause of death and disability due to trauma. Early administration of tranexamic acid may benefit patients with TBI. Objective: To determine whether tranexamic acid treatment initiated in the out-of-hospital setting within 2 hours of injury improves neurologic outcome in patients with moderate or severe TBI. Design, Setting, and Participants: Multicenter, double-blinded, randomized clinical trial at 20 trauma centers and 39 emergency medical services agencies in the US and Canada from May 2015 to November 2017. Eligible participants (N = 1280) included out-of-hospital patients with TBI aged 15 years or older with Glasgow Coma Scale score of 12 or less and systolic blood pressure of 90 mm Hg or higher. Interventions: Three interventions were evaluated, with treatment initiated within 2 hours of TBI: out-of-hospital tranexamic acid (1 g) bolus and in-hospital tranexamic acid (1 g) 8-hour infusion (bolus maintenance group; n = 312), out-of-hospital tranexamic acid (2 g) bolus and in-hospital placebo 8-hour infusion (bolus only group; n = 345), and out-of-hospital placebo bolus and in-hospital placebo 8-hour infusion (placebo group; n = 309). Main Outcomes and Measures: The primary outcome was favorable neurologic function at 6 months (Glasgow Outcome Scale-Extended score >4 [moderate disability or good recovery]) in the combined tranexamic acid group vs the placebo group. Asymmetric significance thresholds were set at 0.1 for benefit and 0.025 for harm. There were 18 secondary end points, of which 5 are reported in this article: 28-day mortality, 6-month Disability Rating Scale score (range, 0 [no disability] to 30 [death]), progression of intracranial hemorrhage, incidence of seizures, and incidence of thromboembolic events. Results: Among 1063 participants, a study drug was not administered to 96 randomized participants and 1 participant was excluded, resulting in 966 participants in the analysis population (mean age, 42 years; 255 [74%] male participants; mean Glasgow Coma Scale score, 8). Of these participants, 819 (84.8%) were available for primary outcome analysis at 6-month follow-up. The primary outcome occurred in 65% of patients in the tranexamic acid groups vs 62% in the placebo group (difference, 3.5%; [90% 1-sided confidence limit for benefit, -0.9%]; P = .16; [97.5% 1-sided confidence limit for harm, 10.2%]; P = .84). There was no statistically significant difference in 28-day mortality between the tranexamic acid groups vs the placebo group (14% vs 17%; difference, -2.9% [95% CI, -7.9% to 2.1%]; P = .26), 6-month Disability Rating Scale score (6.8 vs 7.6; difference, -0.9 [95% CI, -2.5 to 0.7]; P = .29), or progression of intracranial hemorrhage (16% vs 20%; difference, -5.4% [95% CI, -12.8% to 2.1%]; P = .16). Conclusions and Relevance: Among patients with moderate to severe TBI, out-of-hospital tranexamic acid administration within 2 hours of injury compared with placebo did not significantly improve 6-month neurologic outcome as measured by the Glasgow Outcome Scale-Extended. Trial Registration: ClinicalTrials.gov Identifier: NCT01990768.

Actinic keratosis area and severity index is not correlated with photodynamic therapy procedural pain.

BACKGROUND: The Actinic Keratosis Area and Severity Index (AKASI) is a validated quantitative tool used to measure the severity of actinic keratoses. Given the success of AKASI in measuring outcomes and therapies related to actinic damage, we hypothesized that AKASI would be correlated to photodynamic therapy (PDT)-related pain. The aim of this study was to evaluate AKASI's correlation with PDT-associated pain for patients with AKs being treated with 5-Aminolevulinic acid (ALA) PDT. METHODS: Thirty consecutive patients being treated for AKs with ALA PDT on the face and/or scalp were recruited from a single center. The AKASI of the treated areas were collected. The patient underwent a standard treatment with ALA-PDT for a total of 10 J/cm2 to treated area. Immediate post-procedural pain scores were measured using a visual-analog pain scale. Pain and AKASI scores were analyzed using Pearson's correlation coefficient. RESULTS: AKASI was not correlated to pain score (Pearson correlation coefficient was 0.027, p = 0.87). In sub-group analyses, there was no strong correlation between the scalp AKASI or face AKASI and respective pain scores (p = 0.59 and p = 0.38, respectively). Furthermore, there was no strong correlation between the individual components of AKASI and pain score: distribution (p = 0.26), erythema (p = 0.66) and thickness (p = 0.43). CONCLUSION: There is no correlation between the AKASI score and perceived pain from PDT. Therefore, the need for pain relief using a fan and evaporative cooling should be anticipated for all patients. We feel that this negative result is noteworthy as it supports mechanisms outside of AK destruction as the cause of immediate PDT-related pain.

The role of prospection in altruistic bone marrow donation decisions.

OBJECTIVE: The decision to become an unrelated allogeneic bone marrow or hematopoietic stem cell (HSC) donor is a consequential and complex one. Although new registry members pledge to donate if asked in the future, significant proportions ultimately reconsider when they are notified as a potential match for a patient and are asked to undergo confirmatory typing (CT), resulting in many patients failing to receive transplants. We consider the roles of prospection, or thinking about the future, and ambivalence, or having mixed emotions about an event, in this phenomenon. Prospection theory dictates that distant and improbable events are construed more abstractly than near-term and probable events. We hypothesized that construals about donation in new registry members versus those asked to undergo CT would differ in accordance with these patterns, and that variation in construals would be associated with decisions about whether to proceed toward donation. METHOD: In collaboration with the National Marrow Donor Program, we measured donation intentions and CT decisions in 516 new registry members and 213 members asked to undergo CT, respectively. Participants were asked to describe what they imagined would happen in the donation process. RESULTS: We found that the valence and heterogeneity with which registry members construed donation were significant predictors of donation-related decisions. Assuming the temporal ordering of cognitive processes, ambivalence about donation was a mediator of these relationships. CONCLUSIONS: Findings suggest that encouraging a focus on positive central features of marrow and HSC donation may reduce ambivalence and decrease attrition from the registry.

[Strategies in case of metastatic sentinel lymph node in breast cancer]. / Stratégies en cas de positivité du ganglion sentinelle dans les cancers du sein.

Management strategy of micro or macro metastatic sentinel lymph node(s) (SLNs) in breast cancer has dramatically changed over the past ten years and the publication of five randomized trials results: ACOSOG Z0011, IBCSG 23-01, and AATRM comparing axillary lymph node dissection (ALND) versus SLNs biopsy alone; and AMAROS and OTOASOR comparing ALND versus axillary radiotherapy. Despite methodological limitations of several of these trials, notably ACOSOG Z0011, the international recommendations (ASCO, NCCN) and the expert consensus of St Gallen do not recommend the performance of a complementary ALND in case of macro or micro metastatic SLN, if all ACOSOG Z0011 inclusion criteria are met. Moreover, in the context of a mastectomy, with one or two positive SLN and a wall irradiation indication, an axillary radiotherapy can be proposed as an alternative to ALND. Additionally, ALND is also indicated in extracapsular involvement or when three or more SLNs are metastatic. This change in strategy led to a significant decrease on the number of ALNDs performed and resulted on the abandon of SLNs extemporaneous examination. In France, there are no national recommendations on axillary management in the context of SLN involvement. Moreover, a multitude of different local guidelines, led to very heterogeneous practices in our country. The next evolution on axillary management strategy will be the implementation of a SLNs procedure after neoadjuvant chemotherapy (NAC) for patients with lymph node involvement proven before NAC and for whom NAC has allowed axillary downstaging.

Burnout Syndrome in UK Intensive Care Unit staff: Data from all three Burnout Syndrome domains and across professional groups, genders and ages.

INTRODUCTION: This is the first comprehensive evaluation of Burnout Syndrome across the UK Intensive Care Unit workforce and in all three Burnout Syndrome domains: Emotional Exhaustion, Depersonalisation and lack of Personal Accomplishment. METHODS: A questionnaire was emailed to UK Intensive Care Society members, incorporating the 22-item Maslach Burnout Inventory Human Services Survey for medical personnel. Burnout Syndrome domain scores were stratified by 'risk'. Associations with gender, profession and age-group were explored. RESULTS: In total, 996 multi-disciplinary responses were analysed. For Emotional Exhaustion, females scored higher and nurses scored higher than doctors. For Depersonalisation, males and younger respondents scored higher. CONCLUSION: Approximately one-third of Intensive Care Unit team-members are at 'high-risk' for Burnout Syndrome, though there are important differences according to domain, gender, age-group and profession. This data may encourage a more nuanced understanding of Burnout Syndrome and more personalised strategies for our heterogeneous workforce.

Observer-based tools for non-technical skills assessment in simulated and real clinical environments in healthcare: a systematic review.

BACKGROUND: Over the past three decades multiple tools have been developed for the assessment of non-technical skills (NTS) in healthcare. This study was designed primarily to analyse how they have been designed and tested but also to consider guidance on how to select them. OBJECTIVES: To analyse the context of use, method of development, evidence of validity (including reliability) and usability of tools for the observer-based assessment of NTS in healthcare. DESIGN: Systematic review. DATA SOURCES: Search of electronic resources, including PubMed, Embase, CINAHL, ERIC, PsycNet, Scopus, Google Scholar and Web of Science. Additional records identified through searching grey literature (OpenGrey, ProQuest, AHRQ, King's Fund, Health Foundation). STUDY SELECTION: Studies of observer-based tools for NTS assessment in healthcare professionals (or undergraduates) were included if they: were available in English; published between January 1990 and March 2018; assessed two or more NTS; were designed for simulated or real clinical settings and had provided evidence of validity plus or minus usability. 11,101 articles were identified. After limits were applied, 576 were retrieved for evaluation and 118 articles included in this review. RESULTS: One hundred and eighteen studies describing 76 tools for assessment of NTS in healthcare met the eligibility criteria. There was substantial variation in the method of design of the tools and the extent of validity, and usability testing. There was considerable overlap in the skills assessed, and the contexts of use of the tools. CONCLUSION: This study suggests a need for rationalisation and standardisation of the way we assess NTS in healthcare and greater consistency in how tools are developed and deployed.
