Using Deauville Scoring to Guide Consolidative Radiotherapy in Diffuse Large B-Cell Lymphoma.

BACKGROUND: The most common aggressive lymphoma in adults is diffuse large B-cell lymphoma (DLBCL). Consolidative radiotherapy (RT) is often administered to DLBCL patients but guidelines remain unclear, which could lead to unnecessary RT. We aimed to evaluate the value of end-of-treatment PET-CT scans, interpreted using the Deauville score (DV), to guide the utilization of consolidative RT, which may help spare low-risk DLBCL patients from unnecessary RT. METHODS: We included all DLBCL patients diagnosed between 2010 and 2022 at the National Cancer Centre Singapore with DV measured at the end of the first-line chemoimmunotherapy. The outcome measure was time-to-progression (TTP). The predictive value of DV for RT was assessed based on the interaction effect between the receipt of RT and DV in Cox regression models. RESULTS: The data of 349 patients were analyzed. The median follow-up time was 38.1 months (interquartile range 34.0-42.3 months). RT was associated with a significant improvement in TTP amongst the DV4-5 patients (HR 0.33; 95%CI 0.13-0.88; p = 0.027) but not the DV1-3 patients (HR 0.85; 95%CI 0.40-1.81; p = 0.671) (interaction's p = 0.133). Multivariable analysis reported that RT was again significantly associated with improved TTP among the DV4-5 patients (adjusted HR 0.29; 95%CI 0.10-0.80; p = 0.017) but not the DV1-3 group (HR 0.86; 95%CI 0.40-1.86; p = 0.707) (interaction's p = 0.087). CONCLUSION: Our results suggests that DLBCL patients with end-of-treatment PET-CT DV1-3 may not need consolidative RT. Longer follow-up and prospective randomized trials are still necessary to investigate long-term outcomes.

Interrupting inflammatory bowel disease therapy: why, who, when and how to consider medication holidays.

INTRODUCTION: Medication holidays in inflammatory bowel disease (IBD) offer a potential means to balance disease management, costs, and quality of life. This concept is increasingly relevant in light of the chronic nature of IBD, the cumulative side effects associated with long-term pharmacotherapy, and the evolving treatment landscape that now includes a large armamentarium of effective induction, maintenance, and rescue therapies paired with disease monitoring tools that enable early intervention. AREAS COVERED: This review critically examines the rationale, implementation, and risks of medication holidays in IBD. Recent evidence is reviewed to help guide the risks of relapse involved with cessation of therapy. The selection criteria for patients, the necessary monitoring protocols, and strategies for managing potential relapses are outlined. EXPERT OPINION: Despite the potential benefits, medication holidays in IBD involve significant risks and require careful patient selection and active management. Current research highlights a need for improved predictive models and a deeper understanding of patient-specific outcomes and consequences. The future of medication holidays will depend heavily on advancements in noninvasive monitoring technologies and more personalized approaches to therapy. Ultimately, establishing clearer guidelines for safely conducting medication holidays will be crucial in integrating this strategy into routine clinical practice.

Cryotherapy in the Treatment of Early-Stage Breast Cancer.

Breast cancer is one of the most common malignancies, affecting millions of people worldwide annually. The treatment paradigm for early-stage breast cancer is in flux. The focus is now on opportunities to de-escalation treatment to minimize morbidity and maximize patients' quality of life. Recently, percutaneous minimally invasive ablative techniques have been explored. Early trials in small population of patients demonstrated cryoablation to be effective, safe, and well-tolerated in an outpatient setting. Subsequent surgical resection was performed and the ablation success rate was the highest if the tumor was less than 1.5 cm and with < 25% ductal carcinoma in situ component. ACOSOG Alliance Z1072, a phase II trial with curative intent, demonstrated 100% ablation in all tumors smaller than 1 cm and 92% success in lesions without multifocal disease and less than 2 cm in size. There are ongoing prospective clinical trials to investigate the efficacy of cryoablation without surgical excision for treatment of early-stage breast cancer. FROST (Freezing Instead of Removal Of Small Tumors) started in 2016 is ongoing, ICE3 (Cryoablation of Low Risk Small Breast Cancer) started in 2014 just released 5 years results, and COOL-IT: Cryoablation vs Lumpectomy in T1 Breast Cancers is also ongoing. These prospective trials will expand our knowledge on the safety and value of cryoablation. It is crucial to understand the indications, technical nuances, and distinctive imaging findings for cryoablation as it has potential to revolutionize standard surgical practice.

MR radiomics unveils neoadjuvant chemo-responsiveness with insights into selective treatment de-intensification in HPV-positive oropharyngeal carcinoma.

BACKGROUND: Accurate prediction of neoadjuvant chemotherapy (NAC) response allows for NAC-guided personalized treatment de-intensification in HPV-positive oropharyngeal squamous cell carcinoma (OPSCC). In this study, we aimed to apply baseline MR radiomic features to predict NAC response to help select NAC-guided de-intensification candidates, and to explore biological underpinnings of response-oriented radiomics. METHODS: Pre-treatment MR images and clinical data of 131 patients with HPV-positive OPSCC were retrieved from Fudan University Shanghai Cancer Center. Patients were divided into training cohort (n = 47), validation cohort 1 (n = 49) from NAC response-adapted de-intensification trial (IChoice-01, NCT04012502) and real-world validation cohort 2 (n = 35). NAC prediction model using linear support vector machine (SVM) was built and validated. Subsequent nomograms combined radiomics and clinical characteristics were established to predict survival outcomes. RNA-seq and proteomic data were compared to interpret the molecular features underlying radiomic signatures with differential NAC response. FINDINGS: For NAC response prediction, the fusion model with both oropharyngeal and nodal signatures achieved encouraging performance to predict good responders in the training cohort (AUC 0·89, 95% CI, 0·79-0·95) and validation cohort 1 (AUC 0·71, 95% CI, 0·59-0·83). For prognosis prediction, radiomics-based nomograms exhibited satisfactory discriminative ability between low-risk and high-risk patients (PFS, C-index 0·85, 0·76 and 0·83; OS, C-index 0·79, 0·76 and 0·87, respectively) in three cohorts. Expression analysis unveiled NAC poor responders had predominantly enhanced keratinization while good responders were featured by upregulated immune response and oxidative stress. INTERPRETATION: The MR-based radiomic models and prognostic models efficiently discriminate among patients with different NAC response and survival risk, which help candidate selection in HPV-positive OPSCC with regard to personalized treatment de-intensification.

Assessment of De-Escalation of Empirical Antimicrobial Therapy in Medical Wards with Recognized Prevalence of Multi-Drug-Resistant Pathogens: A Multicenter Prospective Cohort Study in Non-ICU Patients with Microbiologically Documented Infection.

Antimicrobial resistance poses a major threat to human health worldwide and the implementation of antimicrobial stewardship programs (ASPs), including antimicrobial de-escalation (ADE), is a multifaceted tool for minimizing unnecessary or inappropriate antibiotic exposure. This was a prospective observational study of 142 non-Intensive Care Unit (ICU) patients with microbiologically documented infection who were initially administered empirical antimicrobial therapy and admitted to the medical wards of 6 tertiary-care hospitals in Greece from January 2017 to December 2018. Patients were divided into two groups, the ADE and non-ADE group, based on whether ADE was applied or not, respectively. Exploratory end-points were ADE feasibility, safety and efficacy. ADE was applied in 76 patients at a median time of 4 days (IQR: 3, 5). An increased likelihood of ADE was observed in patients with urinary tract (OR: 10.04, 95% CI: 2.91, 34.57; p < 0.001), skin and soft tissue (OR: 16.28, 95% CI: 1.68, 158.08; p = 0.016) and bloodstream infections (OR: 2.52, 95% CI: 1, 6.36; p = 0.05). Factors significantly associated with higher rates of ADE were clarithromycin administration, diagnosis of urinary tract infection (UTI), isolation of E. coli, age and symptoms type on admission. Mortality was lower in the ADE group (18.4% vs. 30.3% p < 0.1) and ADE was not significantly associated with the probability of death (p = 0.432). ADE was associated with favorable clinical outcomes and can be performed even in settings with high prevalence of multi-drug resistant (MDR) pathogens without compromising safety.

De-Escalation of Axillary Surgery in Clinically Node-Positive Breast Cancer Patients Treated with Neoadjuvant Therapy: Comparative Long-Term Outcomes of Sentinel Lymph Node Biopsy versus Axillary Lymph Node Dissection.

BACKGROUNDS: This study compares the long-term outcomes of axillary lymph node dissection (ALND) versus sentinel lymph node biopsy (SLNB) in clinically node-positive (cN+) breast cancer (BC) patients treated with neoadjuvant therapy (NAT). METHODS: We conducted a retrospective analysis of 322 cN+ BC patients who became clinically node-negative (ycN0) post-NAT. Patients were categorized based on the final type of axillary surgery performed: ALND or SLNB. Recurrence-free survival (RFS), distant disease-free survival (DDFS), overall survival (OS), and breast cancer-specific survival (BCSS) were evaluated and compared between the two groups. RESULTS: Patients in the SLNB group had significantly better 3-, 5-, and 10-year RFS, DDFS, OS, and BCSS compared to those in the ALND group. The SLNB group also had a higher proportion of patients achieving pathologic complete response (pCR). Multivariate analysis identified pCR, ypN0 status, and SLNB as favorable prognostic factors for all survival metrics. Axillary recurrence rates were low for both groups (0.6-2.1%). CONCLUSIONS: SLNB may be a safe and effective alternative to ALND for selected cN+ BC patients who convert to ycN0 after NAT. These findings suggest that careful patient selection is crucial, and further research is needed to validate these results in more comparable populations.

Multidisciplinary Simulation-Based Verbal De-escalation Training Improves Staff Knowledge and Clinical Environment in an Urban Emergency Department.

OBJECTIVES: Hands-on de-escalation training has been recommended for patient-facing emergency department staff by the Occupational Safety and Health Administration. Additionally, simulation-based learning has been shown to be effective at improving staff knowledge and management of agitated patients. The objective of this study was to evaluate the impact of a multidisciplinary education session on staff knowledge and confidence in verbal de-escalation and violent restraint use, in the clinical environment in an urban emergency department. METHODS: A 90-min mixed didactic and standardized patient encounter educational course with formal debriefing was developed. Learners included nurses, patient support associates, paramedics, and protective services officers from an urban emergency department. Data was obtained from standardized surveys. Lastly, changes to the clinical environment that occurred because of the educational intervention were captured. RESULTS: A total of 117/136 emergency department staff members (86%) completed the de-escalation training. Improved confidence (> 90% agree/strongly agree) in all learning objectives was reported immediately after training and maintained after 6 months. Additionally, the rate of violent restraint use trended down after intervention. Multiple hospital policies, including alterations to physical environment, arrival process, and communication, were enacted as a result of staff feedback during the education. CONCLUSION: A multidisciplinary simulation-based educational course was successful in improving learner confidence in management and de-escalation of agitated patients. This education also led to changes in the clinical environment within the emergency department.

Omission of Axillary Lymph Node Dissection in Patients with Residual Nodal Disease After Neoadjuvant Chemotherapy.

BACKGROUND: Axillary management after neoadjuvant chemotherapy (NAC) is evolving but axillary lymph node dissection (ALND) remains the standard of care for patients with residual nodal disease. The results of the Alliance A011202 trial evaluating the oncologic safety of ALND omission in this cohort are pending but we hypothesize that ALND omission is already increasing. METHODS: The National Cancer Database was queried to identify patients diagnosed with cT1-3N1M0 breast cancer who underwent NAC and had residual nodal disease (ypN1mi-2) from 2012 to 2021. Temporal trends in omission of completion ALND were assessed annually. Multivariable logistic and Cox regression models were used to identify factors associated with ALND omission and overall survival (OS), respectively. RESULTS: A total of 6101 patients were included; the majority presented with cT2 disease (57%), with 69% HER2+, 23% triple-negative, and 8% hormone receptor-positive/HER2-. Overall, 34% underwent sentinel lymph node biopsy (SLNB) alone. Rates of ALND were the lowest in the last 4 years of observation. After adjustment, treatment at community centers (vs. academic) and lower pathologic nodal burden were associated with omission of ALND. ALND omission was associated with a higher unadjusted OS (5-year OS: 86% SLNB alone vs. 84% ALND; log-rank p = 0.03), however this association was not maintained after adjustment. CONCLUSIONS: Despite the impending release of the Alliance A011202 results, omission of ALND in patients with residual nodal disease after NAC is increasing. This practice appears more prominent in community centers and in patients with a lower burden of residual nodal disease. No association with OS was noted.

Treatment De-escalation in Oropharyngeal Carcinoma and the Role of Robotic Surgery.

Oropharyngeal squamous cell carcinoma (OPSCC) related to human papillomavirus (HPV) infection has better survival outcomes compared to non-HPV-related OPSCC, leading to efforts to de-escalate the intensity of treatment to reduce associated morbidity. This article reviews recent clinical efforts to explore different de-escalation frameworks with a particular emphasis on the emergence of transoral robotic surgery and surgically driven de-escalation approaches. It discusses the current evidence for incorporating surgery into an evolving treatment paradigm for HPV-related OPSCC.

Update on the management of ductal carcinoma in situ of the breast: current approach and future perspectives.

The standard treatment for ductal carcinoma in situ became well established through the results of several valuable clinical trials, and its therapeutic benefits have now come to be taken for granted. Ductal carcinoma in situ has an extremely good prognosis with the current treatment approach, with a 10-year breast cancer-specific survival rate of 97-98%. According to one retrospective cohort study, the breast cancer-specific survival rate of patients with low-grade ductal carcinoma in situ does not differ significantly between patients undergoing and not undergoing surgery. Some patients with ductal carcinoma in situ are not at a risk of progression to invasive cancer, but the predictors of such progression have not yet been clearly identified. Therefore, the same therapeutic strategies have been used to treat ductal carcinoma in situ and under the assumption that they have risks of invasive breast cancer, and a well-balanced risk/benefit ratio in respect of treatment has not yet been achieved. Based on the results of several recent clinical trials aimed at ensuring provision of a well-balanced treatment for patients with ductal carcinoma in situ which carries a good prognosis, de-escalation of postoperative adjuvant therapy has now begun. Currently, not only is the optimization of postoperative adjuvant therapy accelerating, but also clinical trials to de-escalate basic surgical treatments are under way. There is a possibility of achieving individualized treatment for patients with ductal carcinoma in situ of the breast with reduced treatment intervention. In this review, we present an overview of the current treatment approaches and potential future management strategies for ductal carcinoma in situ of the breast.

Psychophysiological insights and user perspectives: enhancing police de-escalation skills through full-body VR training.

In recent years, Virtual Reality (VR) has emerged as a promising tool for enhancing training responses in high-stress professions, notably among police officers. This study investigates the psychophysiological responses and subjective user experience of active police officers undergoing Mental Health Crisis Response (MHCR) training using an immersive full-body VR system. A total of 10 active police officers with Special Weapons and Tactics (SWAT) training participated in our controlled study. Officers independently took part in one VR training session lasting 7-12 min involving an avatar in crisis portrayed by an actor. Officers wore integrated cardiovascular and electrodermal activity measurement devices for physiological monitoring. VR user experience aspects such as induced symptoms or game mechanics were investigated upon completing the training, aiming to evaluate the officer's perceptions of the technology. We used the DePICT™ scale to evaluate the de-escalation skills of officers, coded by a research professional. Our findings revealed significant differences in heart rate and heart rate variability responses between baseline and VR scenario immersion, suggesting heightened stress regulation during the MHCR simulation using full-body VR. Arousal measurements also revealed measurable responses during the training in VR. Additionally, the user experience assessment indicated a positive reception to the VR training, with minimal VR-induced symptoms. A "Defensive-Dynamics-Dichotomy" was revealed highlighting dominant autonomic responses linked to defensive actions (e.g., officers who drew a weapon; those who kept their weapons holstered) and their respective implications for stress management and cognitive function. A unique constellation of de-escalation skills was revealed among officers who relied on weapons relative to those who did not, to resolve the scenario. The study highlighted the perceived utility of physiological monitoring technologies in enhancing police training outcomes. In conclusion, our research underscores the potential of VR as an effective tool for de-escalation training following MHCR simulated scenarios among active police officers, offering insights into its psychophysiological impact and user experience. The findings contribute to improving our understanding of the physiology associated with decision-making in police officers to draw a weapon, emphasizing the role of advanced simulation and physiological monitoring technology in developing evidence-based training programs for public safety.

Radiological and pathological predictors of post-operative upstaging of breast ductal carcinoma in situ (DCIS) to invasive ductal carcinoma and lymph-nodes metastasis; a potential algorithm for node surgical de-escalation.

BACKGROUND/AIM: Ductal carcinoma in situ is considered a local disease with no metastatic potential, thus sentinel lymph node biopsy (SLNB) may be deemed an overtreatment. SLNB should be reserved for patients with invasive cancer, even though the risk of upstaging rises to 25 %. We aimed to identify clinicopathological predictors of post-operative upstaging in invasive carcinoma. METHODS: We retrospectively analyzed patients with a pre-operative diagnosis of DCIS subjected to breast surgery between January 2017 to December 2021, and evaluated at the Breast Unit of PTV (Policlinico Tor Vergata, Rome). RESULTS: Out of 267 patients diagnosed with DCIS, 33(12.4 %) received a diagnosis upstaging and 9(3.37 %) patients presented with sentinel lymph node (SLN) metastasis. In multivariate analysis, grade 3 tumor (OR 1.9; 95 % CI 1.2-5.6), dense nodule at mammography (OR 1.3; 95 % CI 1.1-2.6) and presence of a solid nodule at ultrasonography (OR 1.5; 95 % CI 1.2-2.6) were independent upstaging predictors. Differently, the independent predictors for SLNB metastasis were: upstaging (OR 2.1.; 95 % CI 1.2-4.6; p = 0.0079) and age between 40 and 60yrs (OR 1.4; 95 % CI 1.4-2.7; p = 0.027). All 9 patients with SLN metastasis received a diagnosis upstaging and were aged between 40 and 60 years old. CONCLUSION: We identified pre-operative independent predictors of upstaging to invasive ductal carcinoma. The combined use of different predictors in an algorithm for surgical treatments of DCIS could reduce the numbers of unnecessary SLNB.

Escalation and De-Escalation of Adjuvant Radiotherapy in Early Breast Cancer: Strategies for Risk-Adapted Optimization.

Postoperative radiotherapy (RT) is recommended after breast-conserving surgery and mastectomy (with risk factors). Consideration of pros and cons, including potential side effects, demands the optimization of adjuvant RT and a risk-adapted approach. There is clear de-escalation in fractionation-hypofractionation should be considered standard. For selected low-risk situations, PBI only or even the omission of RT might be appropriate. In contrast, tendencies toward escalating RT are obvious. Preoperative RT seems attractive for patients in whom breast reconstruction is planned or for defining the tumor location more precisely with the potential of giving ablative doses. Dose escalation by a (simultaneous integrated) boost or the combination with new compounds/systemic treatments may increase antitumor efficacy but also toxicity. Despite low evidence, RT for oligometastatic disease is becoming increasingly popular. The omission of axillary dissection in node-positive disease led to an escalation of regional RT. Studies are ongoing to test if any axillary treatment can be omitted and which oligometastatic patients do really benefit from RT. Besides technical improvements, the incorporation of molecular risk profiles and also the response to neoadjuvant systemic therapy have the potential to optimize the decision-making concerning if and how local and/or regional RT should be administered.

Prognostic Significance of Human Papillomavirus Genotypes in Oropharyngeal Squamous Cell Carcinoma.

OBJECTIVES: The prognostic significance of human papillomavirus (HPV) genotypes in oropharyngeal squamous cell carcinoma (OPSCC) has garnered considerable attention due to the increasing reliance on HPV status for clinical decision-making. This study aimed to compare the survival outcomes associated with different HPV genotypes in patients with OPSCC relative to HPV-negative tumors, providing insights into the potential implications for treatment de-intensification strategies. METHODS: Patients diagnosed with invasive OPSCC were included from the National Cancer Database (NCDB). Patients were stratified based on HPV status and genotype, with HPV-negative tumors serving as the reference group. Multivariable Cox regression analysis was performed to assess the independent prognostic value of different HPV genotypes. RESULTS: Th majority of patient were classified as HPV-positive (N = 17,358, 70.0%), with HPV 16 being the most common genotype (N = 15410/17358, 88.8%) compared with other high-risk (N = 1217/17,358, 7.0%) and low-risk (N = 731/17,358, 4.2%) HPV genotypes. A significantly lower risk of death was measured for all HPV-positive compared with HPV-negative tumors (HPV 16: adjusted HR 0.51; 95% CI: 0.49-0.54; other high-risk HPV: adjusted HR 0.56; 95% CI: 0.49-0.63; low-risk HPV: adjusted HR 0.59; 95% CI: 0.50-0.68; p < 0.001). CONCLUSION: This study highlights the significant prognostic value of HPV genotypes in OPSCC, underscoring the superior survival outcomes of HPV-positive tumors across all genotypes compared with HPV-negative tumors. Detailed HPV subtype analysis can inform better treatment decisions and support de-intensification strategies for patients with low-risk genotypes. LEVEL OF EVIDENCE: 3 Laryngoscope, 2024.

MS treatment de-escalation: review and commentary.

Almost all currently licensed disease-modifying therapies (DMTs) for MS treatment require prolonged if not lifelong administration. Yet, as people age, the immune system has increasingly reduced responsiveness, known as immunosenescence. Many MS DMTs reduce the responsiveness of the immune system, increasing the risks for infections and possibly cancers. As people with MS (pwMS) age, it is recognized that inflammatory MS activity declines. Several studies have addressed de-escalation of DMTs for relapsing MS under special circumstances. Here, we review evidence for de-escalating DMTs as a strategy that is particularly relevant to pwMS of older age. Treatment de-escalation can involve various strategies, such as extended or reduced dosing, switching from high-efficacy DMTs having higher risks to moderately effective DMTs with lesser risks, or treatment discontinuation. Studies have suggested that for natalizumab extended dosing maintained clinical efficacy while reducing the risk of PML. Extended interval dosing of ocrelizumab mitigated the decline of Ig levels. Retrospective and observational discontinuation studies demonstrate that age is an essential modifier of drug efficacy. Discontinuation of MS treatment in older patients has been associated with a stable disease course, while younger patients who discontinued treatment were more likely to experience new clinical activity. A recently completed 2-year randomized-controlled discontinuation study in 260 stable pwMS > 55 years found stable clinical multiple sclerosis with only a small increased risk of new MRI activity upon discontinuation. DMT de-escalation or discontinuation in MS patients older than 55 years may be non-inferior to continued treatment with immunosuppressive agents having higher health risks. However, despite several small studies, a definite conclusion about treatment de-escalation in older pwMS will require larger and longer studies. Ideally, comparison of de-escalation versus continuation versus discontinuation of DMTs should be done by prospective randomized-controlled trials enrolling sufficient numbers of subjects to allow comparisons for MS patients of both sexes within age groups, such as 55-59, 60-65, 66-69, etc. Optimally, such studies should be 3 years or longer and should incorporate testing for specific markers of immunosenescence (such as T-cell receptor excision circles) to account for differential aging of individuals.

Re-Evaluating the Omission of Radiation Therapy in Low-Risk Patients With Early-Stage Breast Cancer.

Traditionally, management of early-stage breast cancer has required adjuvant radiation therapy following breast conserving surgery, due to decreased local recurrence and breast cancer mortality. However, over the past decade, there has been an increasing emphasis on potential overtreatment of patients with early-stage breast cancer. This has given rise to questions of how to optimize deintensification of treatment in this cohort of patients while maintaining clinical outcomes. A multitude of studies have focused on identification of a subset of patients with invasive breast cancer who were at low risk of local recurrence based on clinicopathologic features and therefore suitable for RT omission. These studies have failed to identify a subset that does not from RT with respect to local control. Several ongoing trials are evaluating alternative approaches to deintensification while focusing on tumor biology. With regards to ductal carcinoma in situ (DCIS), the role of RT has been questioned since breast conservation was utilized. Paralleling invasive disease studies, studies have sought to use clinicopathologic features to identify low risk patients suitable for RT omission but have failed to identify a subset that does not from RT with respect to local control. Use of new assays in patients with DCIS may represent the ideal approach for risk stratification and appropriate deintensification. At this time, when considering deintensification, individualizing treatment decisions with a focus on shared decision making is paramount.

Strategies for optimal management of pediatric acute agitation in emergency settings.

Acute agitation in youth is a challenging presentation to the emergency department. In many cases, however, youth can be behaviorally de-escalated using a combination of environmental modification and verbal de-escalation. In cases where additional strategies such as pharmacologic de-escalation or physical restraint are needed, using the least restrictive means possible, including the youth in the decision-making process, and providing options are important. This paper reviews specific considerations on the approach to a youth with acute agitation and strategies and techniques to successfully de-escalate agitated youth who pose a danger to themselves and/or others.

A multidisciplinary team and patient perspective on omission of surgery after neoadjuvant systemic therapy for early breast cancer: A European Society of Surgical Oncology (ESSO) Research Academy survey.

BACKGROUND: Surgical de-escalation aims to reduce morbidity without compromising oncological outcomes. Trials to de-escalate breast cancer (BC) surgery among exceptional responders after neoadjuvant systemic therapy (NST) are ongoing. Combined patient and clinician insights on this strategy are unknown. METHODS: The European Society of Surgical Oncology Young Surgeons Alumni Club (EYSAC) performed an online survey to evaluate the perspective of multidisciplinary teams (MDTs) on omission of surgery ("no surgery") following complete response to NST for early BC. The aim was to identify MDT considerations and perceived barriers to omission of BC surgery. Patient insights were obtained through a focused group discussion (FGD) with four members of the patient advocacy group, Guiding Researchers and Advocates to Scientific Partnerships (GRASP). RESULTS: The MDT survey had 248 responses, with 229 included for analysis. Criteria for a "no surgery" approach included: patient's tumor and nodal status before (39.7 %) and after (45.9 %) NST and comorbidities (44.3 %). The majority chose standard surgery for hypothetical cases with a complete response to NST. Barriers for implementation were lack of definitive trials (55.9 %), "no surgery" not being discussed in MDTs (28.8 %) and lack of essential diagnostic or therapeutic options (24 %). Patients expressed communication gaps about BC surgery, lack of trust regarding accuracy of imaging, fear of regret and psychosocial burden of choosing less extensive surgery. CONCLUSIONS: Before accepting "no surgery" after complete response to NST, MDTs and patients need level 1 evidence from clinical trials, access to standard diagnostic modalities and treatments. Patient's fear of regretting less surgery need to be acknowledged and addressed.

De-escalating aggression in acute inpatient mental health settings: a behaviour change theory-informed, secondary qualitative analysis of staff and patient perspectives.

BACKGROUND: De-escalation is often advocated to reduce harm associated with violence and use of restrictive interventions, but there is insufficient understanding of factors that influence de-escalation behaviour in practice. For the first time, using behaviour change and implementation science methodology, this paper aims to identify the drivers that will enhance de-escalation in acute inpatient and psychiatric intensive care mental health settings. METHODS: Secondary analysis of 46 qualitative interviews with ward staff (n = 20) and patients (n = 26) informed by the Theoretical Domains Framework. RESULTS: Capabilities for de-escalation included knowledge (impact of trauma on memory and self-regulation and the aetiology and experience of voice hearing) and skills (emotional self-regulation, distress validation, reducing social distance, confirming autonomy, setting limits and problem-solving). Opportunities for de-escalation were limited by dysfunctional risk management cultures/ relationships between ward staff and clinical leadership, and a lack of patient involvement in safety maintenance. Motivation to engage in de-escalation was limited by negative emotion associated with moral formulations of patients and internal attributions for behaviour. CONCLUSION: In addition to training that enhances knowledge and skills, interventions to enhance de-escalation should target ward and organisational cultures, as well as making fundamental changes to the social and physical structure of inpatient mental health wards. Psychological interventions targeting negative emotion in staff are needed to increase motivation. This paper provides a new evidence-based framework of indicative changes that will enhance de-escalation in adult acute mental health inpatient and PICU settings.

Assessing aortic flow with doppler echocardiography in cardiogenic shock: A crucial diagnostic tool.

PURPOSE: Cardiogenic shock still has a high mortality. In order to correctly manage these patients, it is useful to have available haemodynamic parameters, invasive and non-invasive. The aim of this review is to show the current evidence on the use of echocardiographic aortic flow assessment by left ventricular outflow tract - velocity time integral. METHODS: Publications relevant to the discussion of echocardiographic aortic flow assessment by left ventricular outflow tract - velocity time integral and cardiogenic shock, were retrieved from PubMed®. RESULTS: Left ventricular outflow tract - velocity time integral is an easily sampled and reproducible parameter that has already been shown to have prognostic value in various cardiovascular pathologies, including myocardial infarction and heart failure. Although there are still few data available in the literature, the LVOT-VTI also seems to have an important role in CS from prognosis to guidance in the escalation/de-escalation of vasoactive therapy and to support devices by allowing an estimate of patient's probability of response to fluid administration. CONCLUSION: Aortic flow assessment can become a very useful invasive parameter in the management of cardiogenic shock.
