Oncologic emergencies and urgencies: A comprehensive review.

Patients with advanced cancer generate 4 million visits annually to emergency departments (EDs) and other dedicated, high-acuity oncology urgent care centers. Because of both the increasing complexity of systemic treatments overall and the higher rates of active therapy in the geriatric population, many patients experiencing acute decompensations are frail and acutely ill. This article comprehensively reviews the spectrum of oncologic emergencies and urgencies typically encountered in acute care settings. Presentation, underlying etiology, and up-to-date clinical pathways are discussed. Criteria for either a safe discharge to home or a transition of care to the inpatient oncology hospitalist team are emphasized. This review extends beyond familiar conditions such as febrile neutropenia, hypercalcemia, tumor lysis syndrome, malignant spinal cord compression, mechanical bowel obstruction, and breakthrough pain crises to include a broader spectrum of topics encompassing the syndrome of inappropriate antidiuretic hormone secretion, venous thromboembolism and malignant effusions, as well as chemotherapy-induced mucositis, cardiomyopathy, nausea, vomiting, and diarrhea. Emergent and urgent complications associated with targeted therapeutics, including small molecules, naked and drug-conjugated monoclonal antibodies, as well as immune checkpoint inhibitors and chimeric antigen receptor T-cells, are summarized. Finally, strategies for facilitating same-day direct admission to hospice from the ED are discussed. This article not only can serve as a point-of-care reference for the ED physician but also can assist outpatient oncologists as well as inpatient hospitalists in coordinating care around the ED visit.

A legal mapping of 48 WHO member states' inclusion of public health emergency of international concern, pandemic, and health emergency terminology within national emergency legislation in responding to health emergencies.

WHO has determined a public health emergency of international concern (PHEIC) seven times, and beyond this nomenclature declared COVID-19 to be a pandemic. Under the International Health Regulations (IHR), and through their operationalisation in the joint external evaluation (JEE), governments are urged to create suitable legislation to be able to enact a response to a public health emergency. Whether the pandemic declaration had a greater effect than a PHEIC in encouraging goverments to act, however, remains conjecture, as there is no systemic analysis of what each term means in practice and whether either has meaningful legal implications at the national level. We undertook a legal scoping review to assess the utilisation of PHEIC and pandemic language within national legislation in 28 WHO member states. Data were collected from national websites, JEE reviews, COVID Analysis and Mapping of Policies Tool, Natlex, and Oxford Compendium of National Legal Responses to COVID-19. We found that only 16% of countries have any reference to the PHEIC in national legislation and 37·5% of countries reference the term pandemic. This finding paints a weakened picture of the IHR and PHEIC mechanisms. Having such legalese enshrined in legislation might enhance the interaction between WHO determining a PHEIC or declaring a pandemic and resulting action to mitigate transnational spread of disease and enhance health security. Given the ongoing negotiations at WHO in relation to the amendments to the IHR and creation of the pandemic accord, both of which deal with this declaratory power of the PHEIC and pandemic language, negotiators should understand the possible implications of any changes to these proclamations at the national level and for global health security.

Human Immunodeficiency Virus and Hepatitis C Virus-related Disparities in Undergoing Emergency General Surgical Procedures in the United States, 2016-2019.

OBJECTIVE: To determine whether people living with human immunodeficiency virus (PLWHIV) and people living with hepatitis C virus (PLWHCV) experience inequities in receipt of emergency general surgery (EGS) care. BACKGROUND: PLWHIV and PLWHCV face discrimination in many domains; it is unknown whether this extends to the receipt of EGS care. METHODS: Using data from the 2016 to 2019 National Inpatient Sample, we examined 507,458 nonelective admissions of adults with indications for one of the 7 highest-burden EGS procedures (partial colectomy, small-bowel resection, cholecystectomy, operative management of peptic ulcer disease, lysis of peritoneal adhesions, appendectomy, or laparotomy). Using logistic regression, we evaluated the association between HIV/HCV status and the likelihood of undergoing one of these procedures, adjusting for demographic factors, comorbidities, and hospital characteristics. We also stratified analyses for the 7 procedures separately. RESULTS: After adjustment for covariates, PLWHIV had lower odds of undergoing an indicated EGS procedure [adjusted odds ratio (aOR): 0.81; 95% CI: 0.73-0.89], as did PLWHCV (aOR: 0.66; 95% CI: 0.63-0.70). PLWHIV had reduced odds of undergoing cholecystectomy (aOR: 0.68; 95% CI: 0.58-0.80). PLWHCV had lower odds of undergoing cholecystectomy (aOR: 0.57; 95% CI: 0.53-0.62) or appendectomy (aOR: 0.76; 95% CI: 0.59-0.98). CONCLUSIONS: PLWHIV and PLWHCV are less likely than otherwise similar patients to undergo EGS procedures. Further efforts are warranted to ensure equitable access to EGS care for PLWHIV and PLWHCV.

How prepared is the world? Identifying weaknesses in existing assessment frameworks for global health security through a One Health approach.

The COVID-19 pandemic has exposed faults in the way we assess preparedness and response capacities for public health emergencies. Existing frameworks are limited in scope, and do not sufficiently consider complex social, economic, political, regulatory, and ecological factors. One Health, through its focus on the links among humans, animals, and ecosystems, is a valuable approach through which existing assessment frameworks can be analysed and new ways forward proposed. Although in the past few years advances have been made in assessment tools such as the International Health Regulations Joint External Evaluation, a rapid and radical increase in ambition is required. To sufficiently account for the range of complex systems in which health emergencies occur, assessments should consider how problems are defined across stakeholders and the wider sociopolitical environments in which structures and institutions operate. Current frameworks do little to consider anthropogenic factors in disease emergence or address the full array of health security hazards across the social-ecological system. A complex and interdependent set of challenges threaten human, animal, and ecosystem health, and we cannot afford to overlook important contextual factors, or the determinants of these shared threats. Health security assessment frameworks should therefore ensure that the process undertaken to prioritise and build capacity adheres to core One Health principles and that interventions and outcomes are assessed in terms of added value, trade-offs, and cobenefits across human, animal, and environmental health systems.

A Managed Care System with Telemedicine Support for Neurological Emergencies.

OBJECTIVES: Telemedicine is frequently used to provide remote neurological expertise for acute stroke workup and was associated with better functional outcomes when combined with a stroke unit system-of-care. We investigated whether such system-of-care yields additional benefits when implemented on top of neurological competence already available onsite. METHODS: Quality improvement measures were implemented within a "hub-and-spoke" teleneurology network in 11 hospitals already provided with onsite or telestroke expertise. Measures included dedicated units for neurological emergencies, standardization of procedures, multiprofessional training, and quality-of-care monitoring. Intervention effects were investigated in a controlled study enrolling patients insured at 3 participating statutory health insurances diagnosed with acute stroke or other neurological emergencies. Outcomes during the intervention period between November 2017 and February 2020 were compared with those pre-intervention between October 2014 and March 2017. To control for temporal trends, we compared outcomes of patients with respective diagnoses in 11 hospitals of the same region. Primary outcome was the composite of up-to-90-day death, new disability with the need of ambulatory or nursing home care, expressed by adjusted hazard ratio (aHR). RESULTS: We included 1,418 patients post-implementation (55% female, mean age 76.7 ± 12.8 year) and 2,306 patients pre-implementation (56%, 75.8 ± 13.0 year, respectively). The primary outcome occurred in 479/1,418 (33.8%) patients post-implementation and in 829/2,306 (35.9%) pre-implementation. The aHR for the primary outcome was 0.89 (95% confidence interval [CI]: 0.79-0.99, p = 0.04) with no improvement seen in non-participating hospitals between post- versus pre-implementation periods (aHR 1.04; 95% CI: 0.95-1.15). INTERPRETATION: Implementation of a multicomponent system-of-care was associated with a lower risk of poor outcomes. ANN NEUROL 2023;93:511-521.

Preoperative high dose of dexamethasone in emergency laparotomy: randomized clinical trial.

BACKGROUND: Patients undergoing emergency laparotomy present with a profound inflammatory response, which could be an independent pathophysiological component in prolonged recovery. The aim of this study was to investigate the effects of a single preoperative high dose of intravenous dexamethasone on the inflammatory response and recovery after emergency laparotomy. METHODS: In this double-blinded placebo-controlled trial, patients were prospectively stratified according to surgical pathology (intestinal obstruction and perforated viscus) and randomized to preoperative 1 mg/kg dexamethasone or placebo at a ratio of 1 : 1. The primary outcome was C-reactive protein on postoperative day 1. Secondary outcomes were postoperative recovery, morbidity, and mortality. RESULTS: A total of 120 patients were included in the trial. On postoperative day 1, the C-reactive protein response was significantly lower in the dexamethasone group (a median of 170 versus 220 mg/l for dexamethasone and for placebo respectively; P = 0.015; mean difference = 49 (95% c.i. 13 to 85) mg/l) and when stratified according to intestinal obstruction (a median of 60 versus 160 mg/l for dexamethasone and for placebo respectively; P = 0.002) and perforated viscus (a median of 230 versus 285 mg/l for dexamethasone and for placebo respectively; P = 0.035). Dexamethasone administration was associated with improved recovery (better haemodynamics, better pulmonary function, less fatigue, and earlier mobilization). Furthermore, the dexamethasone group had a lower 90-day mortality rate (7% versus 23% for dexamethasone and for placebo respectively; relative risk 0.33 (95% c.i. 0.11 to 0.93); P = 0.023) and a decreased incidence of postoperative major complications (27% versus 45% for dexamethasone and for placebo respectively; relative risk 0.62 (95% c.i. 0.37 to 1.00); P = 0.032). CONCLUSION: A single preoperative high dose of intravenous dexamethasone significantly reduces the inflammatory response after emergency laparotomy and is associated with enhanced recovery and improved outcome.

Changes in Site of Death Among Older Adults Without a COVID-19 Diagnosis During the COVID-19 Pandemic.

BACKGROUND: Understanding how the coronavirus disease 2019 (COVID-19) pandemic affected site of death-an important patient-centered outcome related to end-of-life care-would inform healthcare system resiliency in future public health emergencies. OBJECTIVE: To evaluate the changes in site of death during the COVID-19 pandemic among older adults without a COVID-19 diagnosis. DESIGN: Using a quasi-experimental difference-in-differences method, we estimated net changes in site of death during the pandemic period (March-December 2020) from the pre-pandemic period (January-February 2020), using data on the same months in prior years (2016-2019) as the control. PARTICIPANTS: A 20% sample of Medicare Fee-for-Service beneficiaries aged 66 years and older who died in 2016-2020. We excluded beneficiaries with a hospital diagnosis of COVID-19. MAIN MEASURES: We assessed each of the following sites of death separately: (1) home or community; (2) acute care hospital; and (3) nursing home. KEY RESULTS: We included 1,133,273 beneficiaries without a hospital diagnosis of COVID-19. We found that the proportion of Medicare beneficiaries who died at home or in the community setting increased (difference-in-differences [DID] estimate, + 3.1 percentage points [pp]; 95% CI, + 2.6 to + 3.6 pp; P < 0.001) and the proportion of beneficiaries who died (without COVID-19 diagnosis) in an acute care hospital decreased (- 0.8 pp; 95% CI, - 1.2 to - 0.4 pp; P < 0.001) during the pandemic. We found no evidence that the proportion of deaths in nursing homes changed during the pandemic. CONCLUSIONS: Using national data on older adults without a COVID-19 diagnosis, we found that site of death shifted toward home or community settings during the COVID-19 pandemic. Our findings may inform clinicians and policymakers in supporting end-of-life care during future public health emergencies.

The epidemiological profile of incidence and mortality from epidemics in complex humanitarian emergencies from 1990 to 2022 - A scoping review.

AIM: This study aimed to investigate the impact of communicable diseases with epidemic potential in complex emergency (CE) situations, focusing on the epidemiological profile of incidence and mortality and exploring underlying factors contributing to increased epidemic risks. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review (PRISMA-ScR) guidelines, we conducted a scoping review of articles published between 1990 and 2022. The search included terms related to complex emergencies, communicable diseases, outbreaks, and epidemics. We identified 92 epidemics related to CE occurring in 32 different countries. RESULTS: Communicable diseases like Shigellosis, Cholera, Measles, Meningococcal meningitis, Yellow Fever, and Malaria caused significant morbidity and mortality. Diarrhoeal diseases, particularly Cholera and Shigellosis, had the highest incidence rates. Shigella specifically had an incidence of 241.0 per 1000 (people at risk), with a mortality rate of 11.7 per 1000, while Cholera's incidence was 13.0 per 1000, with a mortality rate of 0.22 per 1000. Measles followed, with an incidence of 25.0 per 1000 and a mortality rate of 0.76 per 1000. Meningococcal Meningitis had an incidence rate of 1.3 per 1000 and a mortality rate of 0.13 per 1000. Despite their lower incidences, yellow fever at 0.8 per 1000 and malaria at 0.4 per 1000, their high case fatality rates of 20.1% and 0.4% remained concerning in CE. The qualitative synthesis reveals that factors such as water, sanitation, and hygiene, shelter and settlements, food and nutrition, and public health and healthcare in complex emergencies affect the risk of epidemics. CONCLUSION: Epidemics during complex emergencies could potentially lead to a public health crisis. Between 1990 and 2022, there have been no statistically significant changes in the trend of incidence, mortality, or fatality rates of epidemic diseases in CE. It is crucial to understand that all epidemics identified in CE are fundamentally preventable.

Short Term Outcomes and Treatment Intensity of Major Cardiovascular Emergencies During the COVID-19 Pandemic in Germany.

OBJECTIVE: There has been a decline in hospital admission rates in many countries since the beginning of the COVID-19 pandemic. Patient selection differed from episodes before the pandemic. This study investigated changes in baseline characteristics as well as the short term mortality rate and probability of receiving an invasive procedure while considering sex disparities. METHODS: Claims data provided by Germany's second largest insurance fund, BARMER, were used. Patients without COVID-19 who were treated for ST segment elevation myocardial infarction (STEMI), non-ST segment elevation myocardial infarction (NSTEMI), acute limb ischaemia (ALI), and stroke between 1 January 2018 and 31 December 2021 were included. Outcomes were compared separately for both sexes between the years before the pandemic (2018/2019) and during the pandemic (2020/2021). Propensity scores with exact matching were used to balance confounders including age, drug prescriptions in the previous year, federal state, month of admission, domiciliary care, and the Elixhauser comorbidities. Short term death and probability of invasive procedures were determined using cumulative incidence functions and Cox regressions. RESULTS: The cohort consisted of 140 989 hospitalisations of 122 340 individual patients (48.3% female) with 102 960 matched cases. Baseline characteristics were similar between episodes in the unmatched cohort. Earlier discharge was observed for all strata except for males with ALI or STEMI, where the probability of early discharge was unchanged. The probability of receiving an invasive procedure was increased for both sexes with ALI, NSTEMI, and STEMI but not for stroke. The analyses suggested neither a statistically significant increase of the in hospital mortality rate nor the 30 day mortality rate after the pandemic started. CONCLUSION: There was no evidence for a direct or indirect impact of the pandemic on major short term hospital outcomes. While the probability of receiving an invasive procedure increased for STEMI, NSTEMI, and ALI, the overall short term mortality rate was unaffected for both sexes.

Prehospital Clinical Decision-Making for Medication Administration for Behavioral Emergencies.

Introduction. Prehospital behavioral emergency protocols provide guidance on when a medication may be necessary; however, the final decision of which medication to administer to a patient is made independently by paramedics. This study sought to describe the clinical decision-making process of prehospital behavioral emergencies when paramedics consider chemical restraints, and determine the factors associated with choosing specific medications to administer. Methods. Paramedics from a Midwest County in the United States were surveyed in November of 2019. The survey consisted of two open-ended questions, measuring paramedics' clinical decision-making process and factors that they considered when selecting a medication. An immersion-crystallization approach was used to analyze the interviews. Results. There was a 53% (79/149) response rate. Six themes emerged regarding the paramedics' decisions to use medication for cases involving patients with behavioral emergencies: safety of the patients and paramedics; inability to use calming techniques; severity of the behavioral emergency; inability to assess the patient due to presentation; etiology of the behavioral episode; and other factors, such as age, size, and weight of the patient. Six themes emerged regarding factors paramedics considered when choosing which medication to use in behavioral emergencies: etiology of the behavioral emergency, patient presentation, the patient's history, the patient's age, desired effect and intended outcome of the medication, and other factors. Conclusion. This study suggests there are several factors, such as safety and the etiology of the behavioral emergency, that contributed to paramedics' decision-making. The results of this study could help Emergency Medical Services administrators in revising behavioral emergency protocols.

Features of databases that supported searching for rapid evidence synthesis during COVID-19: implications for future public health emergencies.

BACKGROUND: As evidence related to the COVID-19 pandemic surged, databases, platforms, and repositories evolved with features and functions to assist users in promptly finding the most relevant evidence. In response, research synthesis teams adopted novel searching strategies to sift through the vast amount of evidence to synthesize and disseminate the most up-to-date evidence. This paper explores the key database features that facilitated systematic searching for rapid evidence synthesis during the COVID-19 pandemic to inform knowledge management infrastructure during future global health emergencies. METHODS: This paper outlines the features and functions of previously existing and newly created evidence sources routinely searched as part of the NCCMT's Rapid Evidence Service methods, including databases, platforms, and repositories. Specific functions of each evidence source were assessed as they pertain to searching in the context of a public health emergency, including the topics of indexed citations, the level of evidence of indexed citations, and specific usability features of each evidence source. RESULTS: Thirteen evidence sources were assessed, of which four were newly created and nine were either pre-existing or adapted from previously existing resources. Evidence sources varied in topics indexed, level of evidence indexed, and specific searching functions. CONCLUSION: This paper offers insights into which features enabled systematic searching for the completion of rapid reviews to inform decision makers within 5-10 days. These findings provide guidance for knowledge management strategies and evidence infrastructures during future public health emergencies.

Association of prehospital lactate levels with base excess in various emergencies - a retrospective study.

OBJECTIVES: Blood gas analysis, including parameters like lactate and base excess (BE), is crucial in emergency medicine but less commonly utilized prehospital. This study aims to elucidate the relationship between lactate and BE in various emergencies in a prehospital setting and their prognostic implications. METHODS: We conducted a retrospective analysis of prehospital emergency patients in Graz, Austria, from October 2015 to November 2020. Our primary aim was to assess the association between BE and lactate. This was assessed using Spearman's rank correlation and fitting a multiple linear regression model with lactate as the outcome, BE as the primary covariate of interest and age, sex, and medical emergency type as confounders. RESULTS: In our analysis population (n=312), lactate and BE levels were inversely correlated (Spearman's ρ, -0.75; p<0.001). From the adjusted multiple linear regression model (n=302), we estimated that a 1 mEq/L increase in BE levels was associated with an average change of -0.35 (95 % CI: -0.39, -0.30; p<0.001) mmol/L in lactate levels. Lactate levels were moderately useful for predicting mortality with notable variations across different emergency types. CONCLUSIONS: Our study highlights a significant inverse association between lactate levels and BE in the prehospital setting, underscoring their importance in early assessment and prognosis in emergency care. Additionally, the findings from our secondary aims emphasize the value of lactate in diagnosing acid-base disorders and predicting patient outcomes. Recognizing the nuances in lactate physiology is essential for effective prehospital care in various emergency scenarios.

Effect of surgeon's seniority and subspeciality interest on mortality after emergency laparotomy: A systematic review and meta-analysis.

AIM: To evaluate effect of surgeon's seniority (trainee surgeon vs. consultant surgeon) and surgeon's subspeciality interest on postoperative mortality in patients undergoing emergency laparotomy (EL). METHOD: A systematic review was conducted and reported according to the Cochrane Handbook for Systematic Reviews and the PRISMA statement standards, respectively. We evaluated all studies comparing the risk of postoperative mortality in patients undergoing EL between (a) trainee surgeon and consultant surgeon, and (b) surgeon without and with subspeciality interest related to pathology. Random effects modelling was applied for the analyses. The certainty of evidence was assessed using the GRADE system. RESULTS: Analysis of 256 844 patients from 13 studies showed no difference in the risk of postoperative mortality between trainee-led and consultant-led EL (OR: 0.76, p = 0.12). However, EL performed by a surgeon without subspeciality interest related to the pathology was associated with a higher risk of postoperative mortality compared with a surgeon with subspeciality interest (OR: 1.38, p < 0.00001). In lower gastrointestinal (GI) pathologies, EL done by upper GI surgeons resulted in higher risk of mortality compared with lower GI surgeons (OR: 1.43, p < 0.00001). In upper GI pathologies, EL done by lower GI surgeons resulted in higher risk of mortality compared with upper GI surgeons (OR: 1.29, p = 0.05). CONCLUSION: While confounding by indication cannot be excluded, level 2 evidence with moderate certainty suggests that trainee-led EL may not increase the risk of postoperative mortality but EL by a surgeon with subspeciality interest related to the pathology may reduce the risk of mortality.

Postoperative outcomes and identification of risk factors for complications after emergency intestinal stoma surgery - a multicentre retrospective study.

AIM: Approximately 4000 patients in the UK have an emergency intestinal stoma formed each year. Stoma-related complications (SRCs) are heterogeneous but have previously been subcategorized into early or late SRCs, with early SRCs generally occurring within 30 days postoperatively. Early SRCs include skin excoriation, stoma necrosis and high output, while late SRCs include parastomal hernia, retraction and prolapse. There is a paucity of research on specific risk factors within the emergency cohort for development of SRCs. This paper aims to describe the incidence of SRCs after emergency intestinal surgery and to identify potential risk factors for SRCs within this cohort. METHOD: Consecutive patients undergoing emergency formation of an intestinal stoma (colostomy, ileostomy or jejunostomy) were identified prospectively from across three acute hospital sites over a 3-year period from the ELLSA (Emergency Laparotomy and Laparoscopic Scottish Audit) database. All patients were followed up for a minimum of 1 year. A multivariate logistic regression model was used to identify risk factors for early and late SRCs. RESULTS: A total of 455 patients were included (median follow-up 19 months, median age 64 years, male:female 0.52, 56.7% ileostomies). Early SRCs were experienced by 54.1% of patients, while 51% experienced late SRCs. A total of 219 patients (48.1%) had their stoma sited preoperatively. Risk factors for early SRCs included end ileostomy formation [OR 3.51 (2.24-5.49), p < 0.001], while preoperative stoma siting was found to be protective [OR 0.53 (0.35-0.83), p = 0.005]. Patient obesity [OR 3.11 (1.92-5.03), p < 0.001] and reoperation for complications following elective surgery [OR 4.18 (2.01-8.69), p < 0.001] were risk factors for late SRCs. CONCLUSION: Stoma-related complications after emergency surgery are common. Preoperative stoma siting is the only truly modifiable risk factor to reduce SRCs, and further research should be aimed at methods of improving the frequency and accuracy of this in the emergency setting.

Postoperative complications and emergency surgeries in colorectal cancer patients <50 years-a national cohort study.

AIM: The incidence of colorectal cancer (CRC) in Sweden is increasing in individuals <50 years. This study aimed to examine differences in postoperative 30-day complications and rate of emergency surgeries in CRC patients <50 years at diagnosis compared to older age groups since population-based research on this topic is scarce. METHOD: This population-based study included data from the Swedish Colorectal Cancer Registry for patients undergoing CRC resection between 2010 and 2018. Bivariate analysis and logistic regression were used to analyse the relationship between age groups (<50, 50-79 and ≥80 years) and probability of postoperative 30-day complications adjusted for gender, tumour localization, neoadjuvant (chemo)radiotherapy and American Society of Anesthesiologists score. RESULTS: In total 33 320 patients were included. Patients <50 years had a lower American Society of Anesthesiologists score, more advanced tumours and received more neoadjuvant treatment. Emergency surgeries were less common in the youngest age group (P < 0.001) as well as overall postoperative 30-day complications: ORadj 0.84 (95% CI 0.74-0.96) compared to those ≥80 years. Surgical complications were more common in age groups <50 and 50-79 years (16.5% and 16.9% respectively) compared to patients ≥80 years (14.1%) (P < 0.001). Anastomotic leakage and intra-abdominal infections were more frequent in patients <50 years (5.7% and 3.5% respectively) compared to age groups 50-79 years (5.1% and 2.8% respectively) and ≥80 years (3.5% and 2.1% respectively) (P < 0.001). Wound infections were more common in the two youngest age groups compared to patients ≥80 years (5.3% vs. 3.7% respectively) (P < 0.001). CONCLUSION: Colorectal cancer patients <50 years and 50-79 years had a higher proportion of surgical complications regarding anastomotic leakage, intra-abdominal infections and wound infections but lower overall postoperative complications. The incidence of surgical emergencies was highest amongst patients ≥80 years. Postoperative diagnostic workup in symptomatic individuals <50 years is warranted.

Emergency radiation therapy in modern-day practice: Now or never, or never again ?

Radiation therapy plays a fundamental role in oncological emergencies such as superior vena cava syndrome (SVCS) and metastatic epidural spinal cord compression (MESCC). These are two examples of critical complications of metastatic cancer in terms of pain and functional impact (respiratory and/or neurological). The aim of this review is to explore the current indications, treatment options and outcomes for emergency radiotherapy regarding to these complications.Regarding SVCS, studies are mostly retrospective and unanimously demonstrated a beneficial effect of radiotherapy on symptom relief. Spinal cord compression remains an indication for urgent radiotherapy, and should be combined with surgery when possible. The innovative stereotactic body radiotherapy (SBRT) showed promising results, however this technique requires small volumes and more time preparation and therefore is often unsuitable for SVCS and MESCC emergencies.This review concluded that radiotherapy has a central role to play within a multimodal approach for SVCS and MESCC treatment. Further prospective studies are needed to confirm the effectiveness of radiation and establish the criteria for selecting patients to benefit from this treatment option.

Risk of insomnia during COVID-19: effects of depression and brain functional connectivity.

Normal sleepers may be at risk for insomnia during COVID-19. Identifying psychological factors and neural markers that predict their insomnia risk, as well as investigating possible courses of insomnia development, could lead to more precise targeted interventions for insomnia during similar public health emergencies. Insomnia severity index of 306 participants before and during COVID-19 were employed to determine the development of insomnia, while pre-COVID-19 psychometric and resting-state fMRI data were used to explore corresponding psychological and neural markers of insomnia development. Normal sleepers as a group reported a significant increase in insomnia symptoms after COVID-19 outbreak (F = 4.618, P = 0.0102, df = 2, 609.9). Depression was found to significantly contribute to worse insomnia (ß = 0.066, P = 0.024). Subsequent analysis found that functional connectivity between the precentral gyrus and middle/inferior temporal gyrus mediated the association between pre-COVID-19 depression and insomnia symptoms during COVID-19. Cluster analysis identified that postoutbreak insomnia symptoms followed 3 courses (lessened, slightly worsened, and developed into mild insomnia), and pre-COVID-19 depression symptoms and functional connectivities predicted these courses. Timely identification and treatment of at-risk individuals may help avoid the development of insomnia in the face of future health-care emergencies, such as those arising from COVID-19 variants.

Stenting as bridge to surgery versus upfront emergency resection for non-metastatic left sided obstructing colorectal cancer: risk of peritoneal recurrence and long-term outcomes.

BACKGROUND: Oncological outcomes of stenting as a bridge to surgery (SBTS) remain a major concern, despite perioperative benefits it offers. This study aims to evaluate the differences in recurrence patterns and survival in patients with non-metastatic, obstructing left sided colon cancers treated by SBTS versus upfront emergency surgery (ES). METHODS: This is a retrospective, single-centre cohort study of 227 consecutive patients with non-metastatic, obstructing left sided colon cancer between 2007 and 2016. Primary outcomes were pattern of recurrence, and survival. Univariate, bivariate and multivariate logistic regression were done to determine relationships between factors and recurrence. Kaplan Meier curves and log rank tests were used to analyse survival outcomes. RESULTS: Of the 227 patients included, 62 underwent SBTS and 165 underwent upfront ES. There was a higher rate of peritoneal recurrence in SBTS group (27.4 vs 15.2% p = 0.034), with no difference observed in overall, liver or lung recurrences. No significant difference in overall survival (p = 0.11), cancer specific survival (p = 0.35), or recurrence free survival (p = 0.107) was observed. Univariate analysis showed that SBTS (OR 2.12, p = 0.036), diabetes mellitus (DM) (OR 2.58, p = 0.013), T4 (OR 2.81, p = 0.001), N + (OR 4.02, p = 0.001), lymphovascular invasion (OR 2.43, p = 0.011) contributed to a higher rate of peritoneal recurrence. Bivariate analysis showed synergistic relationship between T4 tumors and SBTS: in T4 tumors that underwent SBTS, the odds of having peritoneal recurrence was 6.8 times higher when compared to ES (p = 0.004); whilst in T2/3 tumors there was no significant difference observed (OR 1.33, p = 0.55). Multivariable analysis showed SBTS (OR 2.60, p = 0.04), DM (OR 2.88, p = 0.012), N + (OR 2.97, p = 0.026) were significant predictors for peritoneal recurrence. CONCLUSIONS: There are concerns over oncological safety of SBTS even with low rates of stent-related perforation. Higher rates of peritoneal recurrence are seen especially with T4 colon cancers treated with SBTS. SBTS, DM and nodal stage were significant predictors for peritoneal recurrence.
