Abnormal dopamine transporter imaging in pure autonomic failure: a potential biomarker of central nervous system involvement.

BACKGROUND AND PURPOSE: Pure autonomic failure (PAF) is a rare progressive neurodegenerative disease characterized by neurogenic orthostatic hypotension at presentation, without other neurological abnormalities. Some patients may develop other central neurological features indicative of multiple system atrophy or a Lewy body disorder. There are currently no biomarkers to assess possible central nervous system involvement in probable PAF at an early stage. A possibility is to evaluate the nigrostriatal dopaminergic degeneration by imaging of dopamine transporter with DaTscan brain imaging. The objective was to evaluate subclinical central nervous system involvement using DaTscan in PAF. METHODS: We retreospectively reviewed pure autonomic failure patients who were evaluated at the Autonomic Unit between January 2015 and August 2021 and underwent comprehensive autonomic assessment, neurological examination, brain magnetic resonance imaging and DaTscan imaging. DaTscan imaging was performed if patients presented with atypical features which did not meet the criteria for Parkinson's disease or multiple system atrophy or other atypical parkinsonism. RESULTS: In this cohort, the median age was 49.5 years at disease onset, 57.5 years at presentation, and the median disease duration was 7.5 years. Five of 10 patients had an abnormal DaTscan without neurological features meeting the criteria of an alternative diagnosis. Patients with abnormal DaTscan were predominantly males, had shorter disease duration and had more severe genitourinary symptoms. DISCUSSION: Degeneration of nigrostriatal dopaminergic neurons measured using DaTscan imaging can present in patients with PAF without concurrent signs indicating progression to widespread α-synucleinopathy. It is advocated that DaTscan imaging should be considered as part of the workup of patients with emerging autonomic failure who are considered to have PAF.

A population-based analysis of the management of symptoms of depression among patients with stage IV non-small cell lung cancer (NSCLC) in Ontario, Canada.

PURPOSE: Patients with lung cancer can experience significant psychological morbidities including depression. We characterize patterns and factors associated with interventions for symptoms of depression in stage IV non-small cell lung cancer (NSCLC). METHODS: We conducted a population-based cohort study using health services administrative data in Ontario, Canada of stage IV NSCLC diagnosed from January 2007 to September 2018. A positive symptom of depression score was defined by reporting at least one ESAS (Edmonton Symptom Assessment System) depression score ≥ 2 following diagnosis until the end of follow-up (September 2019). Patient factors included age, sex, comorbidity burden, rurality of residence, and neighbourhood income quintile. Interventions included psychiatry assessment, psychology referral, social work referral and anti-depressant medical therapy (for patients ≥ 65 years with universal drug coverage). Multivariable modified Poisson regression models were used to examine the association between patient factors and intervention use for patients who reported symptoms of depression. RESULTS: In the cohort of 13,159 patients with stage IV NSCLC lung cancer, symptoms of depression were prevalent (71.4%, n = 9,397). Patients who reported symptoms of depression were more likely to receive psychiatry assessment/psychology referral (7.8% vs 3.5%; SD [standardized difference] 0.19), social work referral (17.4% vs 11.9%; SD 0.16) and anti-depressant prescriptions (23.8% vs 13.8%; SD 0.26) when compared to patients who did not report symptoms of depression respectively. In multivariable analyses, older patients were less likely to receive any intervention. Females were more likely to obtain a psychiatry assessment/psychology referral or social work referral. In addition, patients from non-major urban or rural residences were less likely to receive psychiatry assessment/psychology referral or social work referral, however patients from rural residences were more likely to be prescribed anti-depressants. CONCLUSIONS: There is high prevalence of symptoms of depression in stage IV NSCLC. We identify patient populations, including older patients and rural patients, who are less likely to receive interventions that will help identifying and screening for symptoms of depression.

Enhancing Symptom Screening and Patient Education Among Patients with Metastatic Lung Cancer: a Qualitative Analysis.

We explored perspectives of patients with metastatic non-small cell lung cancer (mNSCLC) on symptom screening and population-level patient-reported outcome (PRO) data regarding common symptom trajectories in the year after diagnosis. A qualitative study of patients with mNSCLC was conducted at a Canadian tertiary cancer centre. English-speaking patients diagnosed ≥ 6 months prior to study invitation were recruited, and semi-structured one-on-one interviews were conducted. Patient and treatment characteristics were obtained via chart review. Anonymized interview transcripts underwent deductive-inductive coding and thematic content analysis. Among ten participants (5 (50%) females; median (range) age, 68 (56-77) years; median (range) time since diagnosis, 28.5 (6-72) months; 6 (60%) with smoking histories), six themes were identified in total. Two themes were identified regarding symptom screening: (1) screening is useful for symptom self-monitoring and disclosure to the healthcare team, (2) screening of additional quality-of-life (QOL) domains (smoking-related stigma, sexual dysfunction, and financial toxicity) is desired. Four themes were identified regarding population-level symptom trajectory PRO data: (1) data provide reassurance and motivation to engage in symptom self-management, (2) data should be disclosed after an oncologic treatment plan is developed, (3) data should be communicated via in-person discussion with accompanying patient-education resources, and (4) communication of data should include reassurance about symptom stabilization, acknowledgement of variability in patient experience, and strategies for symptom self-management. The themes and recommendations derived from the patient experience with mNSCLC provide guidance for enhanced symptom screening and utilization of population-level symptom trajectory data for patient education.

Identify risk factors for perioperative outcomes in Intracorporeal Urinary Diversion and Extracorporeal Urinary Diversion with Robotic Cystectomy.

INTRODUCTION: The increasing adoption of robotic-assisted cystectomy with intracorporeal urinary diversion (ICUD), despite its complexity, prompts a detailed comparison with extracorporeal urinary diversion (ECUD). Our study at a single institution investigates perioperative outcomes and identifies risk factors impacting the success of these surgical approaches. METHODS: In this retrospective analysis, 174 patients who underwent robotic-assisted cystectomy at the University of Louisville from June 2016 to August 2021 were reviewed. The cohort was divided into two groups based on the urinary diversion method: 30 patients underwent ECUD and 144 underwent ICUD. Data on demographics, complication rates, length of hospital stay, and readmission rates were meticulously collected and analyzed. RESULTS: Operative times were comparable between the ICUD and ECUD groups. However, the ICUD group had a significantly lower intraoperative transfusion rate (0.5 vs. 1.0, p=0.02) and shorter hospital stay (7.8 vs. 12.3 days, p<0.001). Factors such as male sex, smoking history, diabetes mellitus, intravesical therapy, higher ASA, and ACCI scores were associated with increased Clavien-Dindo Grade 3 or higher complications. Age over 70 was the sole factor linked to a higher 90-day readmission rate, with no specific characteristics influencing the 30-day rate. CONCLUSION: Robotic cystectomy with ICUD results in shorter hospitalizations and lower intraoperative transfusion rates compared to ECUD, without differences in operative time, high-grade postoperative complications, or readmission rates. These findings can inform clinical decision-making, highlighting ICUD as a potentially more favorable option in appropriate settings.

Access to symptom screening and severe symptom risk among cancer patients with major mental illness.

INTRODUCTION: Cancer symptom screening has the potential to improve cancer outcomes, including reducing symptom burden among patients with major mental illness (MMI). We determined rates of symptom screening with the Edmonton Symptom Assessment System (ESAS-r) and risk of severe symptoms in cancer patients with MMI. METHODS: This retrospective cohort study used linked administrative health databases of adults diagnosed with cancer between 2007 and 2020. An MMI was measured in the 5 years prior to cancer diagnosis and categorized as inpatient, outpatient, or no MMI. Outcomes were defined as time to first ESAS-r screening and time to first moderate-to-severe symptom score. Cause-specific and Fine and Gray competing events models were used for both outcomes, controlling for age, sex, rural residence, year of diagnosis and cancer site. RESULTS: Of 389,870 cancer patients, 4049 (1.0%) had an inpatient MMI and 9775 (2.5%) had an outpatient MMI. Individuals with inpatient MMI were least likely to complete an ESAS-r (67.5%) compared to those with outpatient MMI (72.3%) and without MMI (74.8%). Compared to those without MMI, individuals with an inpatient or outpatient MMI had a lower incidence of symptom screening records after accounting for the competing risk of death (subdistribution Hazard Ratio 0.77 (95% CI 0.74-0.80) and 0.88 (95% CI 0.86-0.90) respectively). Individuals with inpatient and outpatient MMI status consistently had a significantly higher risk of reporting high symptom scores across all symptoms. CONCLUSIONS: Understanding the disparity in ESAS-r screening and management for cancer patients with MMI is a vital step toward providing equitable cancer care.

Chest radiograph classification and severity of suspected COVID-19 by different radiologist groups and attending clinicians: multi-reader, multi-case study.

OBJECTIVES: To quantify reader agreement for the British Society of Thoracic Imaging (BSTI) diagnostic and severity classification for COVID-19 on chest radiographs (CXR), in particular agreement for an indeterminate CXR that could instigate CT imaging, from single and paired images. METHODS: Twenty readers (four groups of five individuals)-consultant chest (CCR), general consultant (GCR), and specialist registrar (RSR) radiologists, and infectious diseases clinicians (IDR)-assigned BSTI categories and severity in addition to modified Covid-Radiographic Assessment of Lung Edema Score (Covid-RALES), to 305 CXRs (129 paired; 2 time points) from 176 guideline-defined COVID-19 patients. Percentage agreement with a consensus of two chest radiologists was calculated for (1) categorisation to those needing CT (indeterminate) versus those that did not (classic/probable, non-COVID-19); (2) severity; and (3) severity change on paired CXRs using the two scoring systems. RESULTS: Agreement with consensus for the indeterminate category was low across all groups (28-37%). Agreement for other BSTI categories was highest for classic/probable for the other three reader groups (66-76%) compared to GCR (49%). Agreement for normal was similar across all radiologists (54-61%) but lower for IDR (31%). Agreement for a severe CXR was lower for GCR (65%), compared to the other three reader groups (84-95%). For all groups, agreement for changes across paired CXRs was modest. CONCLUSION: Agreement for the indeterminate BSTI COVID-19 CXR category is low, and generally moderate for the other BSTI categories and for severity change, suggesting that the test, rather than readers, is limited in utility for both deciding disposition and serial monitoring. KEY POINTS: • Across different reader groups, agreement for COVID-19 diagnostic categorisation on CXR varies widely. • Agreement varies to a degree that may render CXR alone ineffective for triage, especially for indeterminate cases. • Agreement for serial CXR change is moderate, limiting utility in guiding management.

Medical management of secondary postpartum haemorrhage: A prospective cohort study.

BACKGROUND: Secondary postpartum haemorrhage (PPH) complicates ~1% of pregnancies and can cause serious maternal morbidity. However, evidence guiding optimal management is scarce and often based on case series and expert opinion. AIMS: To measure the success of primary medical therapy in managing secondary PPH and to identify factors associated with need for surgical management. MATERIALS AND METHODS: Postpartum patients presenting to a tertiary women's hospital emergency department between July 2020 and October 2021 with secondary PPH were recruited. Data from the acute presentation were prospectively collected. Antenatal and intrapartum data were collected from medical record review. The primary outcome was the success of medical management for secondary PPH, defined by the implementation of medical or expectant measures without subsequent need for surgical intervention. RESULTS: One-hundred and twenty patients underwent primary medical management for secondary PPH. Ninety-eight (82%) were managed successfully with medical management and 22 (18%) required surgery. Medical management involved misoprostol (n = 33; 27.5%), antibiotics (n = 108; 90%), and less commonly other uterotonics (n = 6; 5%). Factors associated with lower rates of successful medical management included: antecedent manual removal of placenta (MROP) (odds ratio (OR) 0.2, P = 0.047), primary PPH ≥500 mL (OR 0.39, P = 0.048) or ≥1 L (OR 0.24, P = 0.009), >200 mL blood loss at presentation (OR 0.17, P = 0.015), increasing time post-delivery (OR 0.84, P = 0.044), retained products of conception (RPOC) on ultrasound (OR 0.024, P = 0.001) and vaginal birth (OR 0.27, P = 0.027). CONCLUSION: Medical management was highly successful. Vaginal birth, MROP, primary PPH, RPOC on ultrasound and increasing time post-delivery were associated with increased need for surgical management.

Economic cost of secondary postpartum haemorrhage: A case-control study at a tertiary hospital in Australia.

BACKGROUND: Secondary postpartum haemorrhage (PPH) is a condition which affects 0.2-3.0% of women. Despite its impact on maternal morbidity, there is a lack of understanding of the cost burden of disease. AIMS: To determine the economic cost of secondary PPH in the postpartum period, compared to the costs for women without this diagnosis. MATERIALS AND METHODS: Data were prospectively collected on a cohort of 97 women who presented with secondary PPH to the emergency department (ED) between July 2020 and February 2021. A case-control design was then used to compare postpartum cost data from these patients to a group of 97 controls who were matched to maternal demographics, and who did not present with secondary PPH. RESULTS: For women with secondary PPH, there were significantly more hospital attendances, and postpartum costs were higher for all cost subcategories across ED, admissions, and outpatient attendances (P < 0.0001), compared to controls. The total cost of postpartum care for 97 patients with secondary PPH was $254 377.62 with an average cost per patient of $2622.45, compared to $26 670.46 for 97 controls with an average cost of $274.95 per patient (P < 0.0001). This demonstrates a 9.5-fold increase in postpartum costs per woman with secondary PPH. CONCLUSIONS: Secondary PPH is an under-researched condition which presents a significant cost burden for the health system. Evidence-based guidelines addressing the prevention and management of secondary PPH may assist in minimising this cost burden for both the health service and the patient.

Textbook Outcome and Survival in Patients With Gastric Cancer: An Analysis of the Population Registry of Esophageal and Stomach Tumours in Ontario (PRESTO).

OBJECTIVE: To examine the association between Textbook Outcome (TO)-a new composite quality measurement-and long-term survival in gastric cancer surgery. BACKGROUND: Single-quality indicators do not sufficiently reflect the complex and multifaceted nature of perioperative care in patients with gastric adenocarcinoma. METHODS: All patients undergoing gastrectomy for nonmetastatic gastric adenocarcinoma registered in the Population Registry of Esophageal and Stomach Tumours of Ontario (PRESTO) between 2004 and 2015 were included. TO was defined according to negative margins; >15 lymph nodes sampled; no severe complications; no re-interventions; no unplanned ICU admission; length of stay ≤21 days; no 30-day readmission; and no 30-day mortality. Three-year survival was estimated using the Kaplan-Meier method. A marginal multivariable Cox proportional-hazards model was used to estimate the association between achieving TO metrics and long-term survival. E-value methodology was used to assess for risk of residual confounding. RESULTS: Of the 1836 patients included in this study, 402 (22%) achieved all TO metrics. TO patients had a higher 3-year survival rate compared to non-TO patients (75% vs 55%, log-rank P < 0.001). After adjustments for covariates and clustering within hospitals, TO was associated with a 41% reduction in mortality (adjusted hazards ratio 0.59, 95% confidence interval 0.48, 0.72, P < 0.001). These results were robust to potential residual confounding. CONCLUSIONS: Achieving TO is strongly associated with improved long-term survival in gastric cancer patients and merits further focus in surgical quality improvement efforts.

Stereotactic Ablative Radiotherapy for the Management of Liver Metastases from Neuroendocrine Neoplasms: A Preliminary Study.

INTRODUCTION: Liver metastases are common in patients with neuroendocrine neoplasms. The role of stereotactic ablative radiotherapy (SABR) is not well understood in this population. OBJECTIVE: The objective of this study was to evaluate the safety and efficacy of SABR in treating well-differentiated neuroendocrine liver metastases (WD-NELM). METHODS: A retrospective review of patients with WD-NELM treated with SABR was conducted between January 2015 and July 2019. Demographic, treatment, and clinical/radiographic follow-up data were abstracted. RECIST 1.1 criteria were applied to each individual target to evaluate the response to treatment. Local control (LC) and progression-free survival (PFS) were determined using the Kaplan-Meier methodology. Toxicity was reported according to the CTCAE v5.0. RESULTS: Twenty-five patients with a total of 53 liver metastases treated with SABR were identified. Most patients (68%) had midgut tumors, were grade 2 (80%), and had high-volume intrahepatic and/or extrahepatic disease (76%). The median number of liver metastases treated was 2, with a median size of 2.5 cm. The median radiation dose delivered was 50 Gy/5 fractions. The median follow-up was 14 months; 24 of the 25 patients were alive at the time of analysis. The objective response rate was 32%, with improvement or stability in 96% of lesions treated. The median time to best response was 9 months. The 1-year LC and PFS were 92 and 44%, respectively. No grade 3/4 acute or late toxicity was identified. CONCLUSIONS: Liver SABR is a safe and promising means of providing LC for WD-NELM. This treatment modality should be evaluated in selected patients in concert with strategies to manage systemic disease.

Province-Wide Analysis of Patient-Reported Outcomes for Stage IV Non-Small Cell Lung Cancer.

BACKGROUND: In Ontario, Canada, patient-reported outcome (PRO) evaluation through the Edmonton Symptom Assessment System (ESAS) has been integrated into clinical workflow since 2007. As stage IV non-small cell lung cancer (NSCLC) is associated with substantial disease and treatment-related morbidity, this province-wide study investigated moderate to severe symptom burden in this population. MATERIALS AND METHODS: ESAS collected from patients with stage IV NSCLC diagnosed between 2007 and 2018 linked to the Ontario provincial health care system database were studied. ESAS acquired within 12 months following diagnosis were analyzed and the proportion reporting moderate to severe scores (ESAS ≥4) in each domain was calculated. Predictors of moderate to severe scores were identified using multivariable Poisson regression models with robust error variance. RESULTS: Of 22,799 patients, 13,289 (58.3%) completed ESAS (84,373 assessments) in the year following diagnosis. Patients with older age, with high comorbidity, and not receiving active cancer therapy had lower ESAS completion. The majority (94.4%) reported at least one moderate to severe symptom. The most prevalent were tiredness (84.1%), low well-being (80.7%), low appetite (71.7%), and shortness of breath (67.8%). Most symptoms peaked at diagnosis and, while declining, remained high in the following year. On multivariable analyses, comorbidity, low income, nonimmigrants, and urban residency were associated with moderate to severe symptoms. Moderate to severe scores in all ESAS domains aside from anxiety were associated with radiotherapy within 2 weeks prior, whereas drowsiness, low appetite and well-being, nausea, and tiredness were associated with systemic therapy within 2 weeks prior. CONCLUSION: This province-wide PRO analysis showed moderate to severe symptoms were prevalent and persistent among patients with metastatic NSCLC, underscoring the need to address supportive measures in this population especially around treatments. IMPLICATIONS FOR PRACTICE: In this largest study of lung cancer patient-reported outcomes (PROs), stage IV non-small cell lung cancer patients had worse moderate-to-severe symptoms than other metastatic malignancies such as breast or gastrointestinal cancers when assessed with similar methodology. Prevalence of moderate-to-severe symptoms peaked early and remained high during the first year of follow-up. Symptom burden was associated with recent radiation and systemic treatments. Early and sustained PRO collection is important to detect actionable symptom progression, especially around treatments. Vulnerable patients (e.g., older, high comorbidity) who face barriers in attending in-person clinic visits had lower PRO completion. Virtual PRO collection may improve completion.

COVID-19 in the act: incidental 18F-FDG PET/CT findings in asymptomatic patients and those with symptoms not primarily correlated with COVID-19 during the United Kingdom coronavirus lockdown.

PURPOSE: The emergence of the novel SARS-CoV-2 pathogen and lethal COVID-19 disease pandemic poses major diagnostic challenges. The study aims to describe the spectrum and prevalence of thoracic and extrathoracic incidental findings in patients who have undergone 18F-FDG PET/CT during the first 3 weeks of the COVID-19 UK lockdown. METHODS: This is a single-centre retrospective controlled observational study. 18F-FDG PET/CT scans (n = 160) acquired from 23/3/2020 to 9/4/2020 were retrospectively reviewed for incidental findings in the lungs and extrapulmonary sites (heart, nasal sinuses, parotid and salivary glands, colon, large vessels, renal cortex, brain, spleen and testes). A date-matched control group (n = 205) of patients from 2019 was used for comparison. RESULTS: The total prevalence of suspicious findings was 26/160 (16.25%). Fifteen patients presented with incidental findings in the lungs, while eleven patients had only non-pulmonary incidental findings. There was a significant increase in the appearance of incidental 18F-FDG PET/CT findings during the 2nd week (OR = 3.8) and 3rd week (OR = 7.6) in relation to the 1st week. There was a significant increase in the average maximum standardised uptake values (SUVmax) in the parotid/salivary glands of patients scanned during week 2 in relation to week 1 (p = 0.036). There was no significant difference in the prevalence of incidental findings compared to the control group, but the number of pulmonary vs. extrathoracic findings was different between the two populations. CONCLUSION: The study provides a novel base of evidence to identify asymptomatic patients and those without symptoms strongly associated with COVID-19 with incidental 18F-FDG PET/CT findings suspicious of SARS-CoV-2 infection during the initial stages of the pandemic.

Association Between Preoperative Patient-Reported Symptoms and Postoperative Outcomes in Rectal Cancer Patients: A Retrospective Cohort Study.

BACKGROUND: Rectal cancer patients undergoing preoperative radiotherapy experience a significant symptom burden. However, it is unknown whether symptoms during radiotherapy may portend adverse postoperative outcomes and healthcare utilization. METHODS: A retrospective cohort study was performed of rectal cancer patients undergoing neoadjuvant radiotherapy and proctectomy in Ontario from 2007 to 2014. The primary outcome was a complicated postoperative course-a dichotomous variable created as a composite of postoperative mortality, major morbidity, or hospital readmission. Patient-reported Edmonton Symptom Assessment System (ESAS) scores, collected routinely at outpatient provincial cancer center visits, were linked to administrative healthcare databases. The receiver-operating characteristic analysis was used to compare ESAS scoring approaches and to stratify patients into low versus high symptom score groups. Multivariable regression models were constructed to evaluate associations between preoperative symptom scores and postoperative outcomes. RESULTS: 1455 rectal cancer patients underwent sequential radiotherapy and proctectomy during the study period and recorded symptom assessments. Patients with high preoperative symptom scores were significantly more likely to experience a complicated postoperative course (OR 1.55, 95% CI 1.23-1.95). High preoperative ESAS scores were also associated with the secondary outcomes of emergency department visits (OR 1.34, 95% CI 1.08-1.66) and longer length of stay (IRR 1.23, 95% CI 1.04-1.45). CONCLUSIONS: Rectal cancer patients reporting elevated symptom scores during neoadjuvant radiotherapy have increased odds of experiencing a complicated postoperative course. Preoperative patient-reported outcome screening may be a useful tool to identify at-risk patients and to efficiently direct perioperative supportive care.

Geographic impact on access to care and survival for non-curative esophagogastric cancer: a population-based study.

BACKGROUND: Among patients not undergoing curative-intent therapy for esophagogastric cancer, access to care may vary. We examined the geographic distribution of care delivery and survival and their relationship with distance to cancer centres for non-curative esophagogastric cancer, hypothesising that patients living further from cancer centres have worse outcomes. METHODS: We conducted a population-based analysis of adults with non-curative esophagogastric cancer from 2005 to 2017 using linked administrative healthcare datasets in Ontario, Canada. Outcomes were medical oncology consultation, receipt of chemotherapy, and overall survival. Using geographic information system analysis, we mapped locations of cancer centres and outcomes across census divisions. Bivariate choropleth maps identified regional outcome discordances. Multivariable regression models assessed the relationship between distance from patient residence to the nearest cancer centre and outcomes, adjusting for demographic, clinical, and socioeconomic factors. RESULTS: Of 10,228 patients surviving a median 5.1 months (IQR: 2.0-12.0), 68.5% had medical oncology consultation and 32.2% received chemotherapy. Certain distances (reference ≤ 10 km) were associated with lower consultation [relative risk 0.79 (95% CI 0.63-0.97) for ≥ 101 km], chemotherapy receipt [relative risk 0.67 (95% CI 0.53-0.85) for ≥ 101 km], and overall survival [hazard ratio 1.07 (95% CI 1.02-1.13) for 11-50 km, hazard ratio 1.13 (95% CI 1.04-1.23) for 51-100 km]. CONCLUSION: A third of patients did not see medical oncology and most did not receive chemotherapy. Outcomes exhibited high geographic variability. Location of residence influenced outcomes, with inferior outcomes at certain distances > 10 km from cancer centres. These findings are important for designing interventions to reduce access disparities for non-curative esophagogastric cancer care.

Patient-reported symptoms in metastatic gastric cancer patients in the last 6 months of life.

BACKGROUND: Patients with metastatic gastric cancer have poor survival outcomes and may experience high symptom burden. We evaluated symptom trajectory and risk factors for increased symptom severity among metastatic gastric cancer patients during the last 6 months of life. METHODS: We conducted a retrospective cohort study among patients ≥ 18 years diagnosed with metastatic gastric cancer from January 2007 to December 2014 in the province of Ontario, Canada. We included patients who died during the study period and who reported at least one Edmonton Symptom Assessment System (ESAS) score during the last 6 months of life. We described the proportion of patients who reported moderate-to-severe symptom scores (≥ 4) by month. Multivariable logistic regression models were created to identify risk factors for moderate-to-severe symptom scores. RESULTS: Seven hundred eighty-eight eligible patients with 3286 unique symptom scores completed during their last 6 months of life were identified. The highest prevalence of moderate-to-severe scores was observed for tiredness and lack of appetite, while nausea and depression had the lowest prevalence of elevated scores. The prevalence of moderate-to-severe was consistently high for all symptoms, particularly approaching end-of-life. Timing of ESAS scores, receipt of cancer-directed therapy, urban residence, and female sex were associated with increased odds of reporting moderate-to-severe symptom scores. CONCLUSION: Patients with metastatic gastric cancer experience significant symptom burden at the end-of-life. Routine screening with patient-reported outcome tools may assist in shared decision-making and effective palliative care by ensuring patients' health status and supportive care needs are identified promptly at the time of clinical encounters.

Berlin Heart EXCOR Support in the First Year of Life: A Single Centre Experience.

BACKGROUND: Berlin Heart EXCOR Pediatric Ventricular Assist Device (BHE) (Berlin Heart AG, Berlin, Germany, BHE) is used worldwide for mechanical circulatory support as a bridge to transplantation or recovery for children with end-stage heart failure. The study aim was to evaluate morbidity and mortality of children less than one year old supported with BHE to identify predictors of adverse outcomes. METHODS: Data of all children aged less than one year supported with BHE between 2005 and 2018 at the Royal Children's Hospital, Melbourne were reviewed. Adverse events were defined using PediMACS criteria. RESULTS: Fourteen (14) children under 1 year of age were implanted with BHE at a median age and weight of 0.37 years (IQR 0.09-0.7) and 5.7 kg (IQR 3.5-7.95) respectively. Four (4) patients were neonates, and 10 were older infants. Twelve (12) patients had cardiomyopathy and two, myocarditis. Preoperative extracorporeal membrane oxygenation (ECMO) support was required in six patients for a mean of 9 days (IQR 6-13). Sepsis occurred in five patients (36%) and thromboembolic stroke in two patients (14%). Survival to bridge to transplantation (11) and recovery (1) was achieved in 12 patients (86%). Mortality was 14%. The median duration of BHE support was 110 days (IQR 40-161). Both patients who died were neonates with myocarditis and required surgical re-intervention during BHE support. CONCLUSIONS: BHE provides excellent support as a bridge to transplantation or recovery in infants, with a low incidence of neurological dysfunction. Neonates with myocarditis may be at greater risk for death after BHE implantation.

Risk of venous thromboembolism in patients with elevated INR undergoing hepatectomy: an analysis of the American college of surgeons national surgical quality improvement program registry.

BACKGROUND: Patients undergoing hepatectomy can have elevated INR and may have venous thromboembolism (VTE) prophylaxis withheld as a result. We sought to examine the association between preoperative INR elevation and VTE following hepatectomy. METHODS: Hepatectomies captured in the American College of Surgeons National Surgical Quality Improvement Program registry between 2007 and 2016 were analyzed. Univariable and multivariable models examined the effect of incremental increases in preoperative INR on 30-day VTE, perioperative transfusion, serious morbidity, and mortality, adjusting for potential confounders. RESULTS: We included 25,220 elective hepatectomies (62.4% partial lobectomies, 10.1% left hepatectomies, 18.6% right hepatectomies, 9.2% trisegmentectomies). The median age of the patients was 60 years and 49% were male. INR was elevated in 3089 patients (12.2%): 1.1-1.2 in 8.1%, 1.2-1.4 in 3.3%, and 1.4-2.0 in 0.9%. Incremental elevations in INR were independently associated with increasing risk for postoperative VTE [odds ratio (OR) 1.15, 95% confidence intervals 1.01-1.31], perioperative transfusion [OR 1.35 (1.28-1.43)], serious morbidity [OR 1.35 (1.28-1.43)], and mortality [OR 1.76 (1.56-1.98)]. CONCLUSION: Elevation in preoperative INR was counter-intuitively associated with increased risk of both VTE and perioperative transfusion following hepatectomy. The role of perioperative thromboprophylaxis warrants further investigation to determine optimal care in patients with elevated preoperative INR.

The impact of tranexamic acid on administration of red blood cell transfusions for resection of colorectal liver metastases.

BACKGROUND: Red blood cell transfusions (RBCT) remain a concern for patients undergoing hepatectomy. The effect of tranexamic acid (TXA), an anti-fibrinolytic, on receipt of RBCT in colorectal liver metastases (CRLM) resection was examined. METHODS: Hepatectomies for CRLM over 2009-2014 were included. Primary outcome was 30-day receipt of RBCT. Secondary outcomes were 30-day major morbidity (Clavien-Dindo III-V) and 90-day mortality. Multivariable modelling examined the adjusted association between TXA and outcomes. RESULTS: Of 433 included patients, 146 (34%) received TXA. TXA patients were more likely to have inflow occlusion (41.8% vs. 23.1%; p < 0.01) and major hepatectomies (56.1% vs. 45.6%; p = 0.0193). TXA was independently associated with lower risk of RBCT (Relative risk (RR) 0.59; 95% confidence interval (95%CI): 0.42-0.85), but not with 30-day major morbidity (adjusted RR 1.02; 95%CI: 0.64-1.60) and 90-day mortality (univariable RR 0.99; 95%CI: 0.95-1.03). CONCLUSION: Intraoperative TXA was associated with a 41% reduction in risk of 30 -day receipt of RBCT after hepatectomy for CRLM. This finding is important to potentially improve healthcare resource allocation and patient outcomes. Pending further evidence, intraoperative TXA may be an effective method of reducing RBCT in hepatectomy for CRLM.

Material deprivation and access to cancer care in a universal health care system.

BACKGROUND: The role of socioeconomic factors as determinants of oncology consultations for advanced cancers in public payer health care systems is unknown. This study examined the association between material deprivation and receipt of cancer care among patients with advanced gastrointestinal (GI) cancer. METHODS: This was a population-based, retrospective cohort study of noncuratively treated patients with GI cancer diagnosed from 2007 to 2017. Material deprivation, representing income, quality of housing, education, and family structure, was defined as quintiles on the basis of 2016 census data. The first consultation with a radiation oncologist or medical oncologist and the receipt of 1 or more instances of radiation and/or chemotherapy were measured in the year after diagnosis. Adjusted, cause-specific Cox proportional hazards competing risk analyses were used (competing event = death). RESULTS: This study included 34,022 noncuratively treated patients with GI cancer. Consultation rates ranged from 67.8% for those in the most materially deprived communities to 73.5% for those in the least materially deprived communities. Among those with a consult, rates of cancer-directed therapy ranged from 58.5% for patients in the most materially deprived communities to 62.3% for patients in the least materially deprived communities. Patients living in the most materially deprived communities were significantly less likely to see a radiation and/or medical oncologist after a diagnosis (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.85-0.92) and significantly less likely to receive radiation and/or chemotherapy (HR, 0.80; 95% CI, 0.76-0.85) than those living in the least materially deprived communities. CONCLUSIONS: This study identified socioeconomic disparities in accessing cancer care. Continued efforts at examining and developing evidence-based policies for interventions that begin before or at the time of oncologist consultation are required to address root causes of inequities.

Gaps in the Management of Depression Symptoms Following Cancer Diagnosis: A Population-Based Analysis of Prospective Patient-Reported Outcomes.

BACKGROUND: One of the most common psychological morbidities of cancer is depression. Routine depression symptoms screening (DSS) is recommended, but its ability to lead to psychosocial interventions in clinical practice is limited. We examined the use of and factors associated with psychosocial interventions for positive DSS following cancer diagnosis. MATERIALS AND METHODS: We conducted a population-based cohort study of patients with diagnoses from 2010 to 2017 who reported ≥1 patient-reported Edmonton Symptom Assessment System (ESAS) score. Positive DSS was defined as ESAS ≥2 out of 10 for the depression item within 6 months of diagnosis. Outcomes were psychosocial interventions around the time of positive DSS: palliative care assessment, psychiatry/psychology assessment, social work referral, and antidepressant therapy (in patients ≥65 years of age with universal drug coverage). We examined reduction in depression symptom score (≥1 point) following intervention. Modified Poisson regression examined factors associated with interventions. RESULTS: Of 142,270 patients, 65,424 (46.0%) reported positive DSS at a median of 66 days (interquartile range: 34-105) after diagnosis. Of those with depression symptoms, 17.1% received palliative assessment, 1.7% psychiatry/psychology assessment, 8.4% social work referral, and 4.3% antidepressant therapy. Depression symptom score decreased in 67.2% who received palliative assessment, 63.7% with psychiatry/psychology assessment, 67.3% with social work referral, and 71.4% with antidepressant therapy. On multivariable analysis, patients with older age, rural residence, lowest income quintile, and genitourinary or oropharyngeal cancer were more likely to not receive intervention other than palliative care. CONCLUSION: The proportion of patients reporting positive DSS after cancer diagnosis receiving psychosocial intervention is low. We identified patients vulnerable to not receiving interventions, who may benefit from additional support. These data represent a call to action to modify practice and optimize the usefulness of systematic symptom screening. IMPLICATIONS FOR PRACTICE: Patient-reported depression symptoms screening should be followed by targeted interventions to improve symptoms and patient-centered management.
