AbstractNasogastric/nasoenteric (NG/NE) feeding tube placements are associated with adverse events and, without proper training, can lead to devastating and significant patient harm related to misplacement. Safe feeding tube placement practices and verification are critical. There are many procedures and techniques for placement and verification; this paper provides an overview and update of techniques to guide practitioners in making clinical decisions. Regardless of placement technique and verification practices employed, it is essential that training and competency are maintained and documented for all clinicians placing NG/NE feeding tubes. This paper has been approved by the American Society for Parenteral and Enteral Nutrition (ASPEN) Board of Directors.

Abstract Objectives To describe the methodology and implications of the patient‐identified most bothersome symptom (PI‐MBS) measure used in the phase 3, multicenter, randomized, double‐blind, placebo‐controlled, and parallel‐group PROMISE‐2 trial and to evaluate the contribution of this measure to the assessment of the preventive migraine benefits of treatment. Background Although freedom from MBS is a coprimary endpoint in acute migraine treatment trials, its evaluation in preventive migraine trials is limited. The PROMISE‐2 study assessed a unique PI‐MBS measure as a secondary endpoint. Methods This was a secondary analysis of data from the PROMISE‐2 study. Adults with chronic migraine (CM) were randomized to receive intravenous (IV) eptinezumab 100 mg, eptinezumab 300 mg, or placebo, administered on day 0 and every 12 weeks. At the screening visit, patients were asked to verbally describe the MBS associated with their CM; the question format was open ended. At subsequent visits, patients were asked to rate the overall change in severity of their MBS from study inception to that time point, using a 7‐point ordinal scale ranging from “very much worse” (−3) to “very much improved” (+3). Patients completed the Patient Global Impression of Change (PGIC) assessment during the same visits, using an identical rating scale and recall period. Endpoints were summarized descriptively; post hoc correlations using the methodologies of Pearson and Spearman were calculated to evaluate relationships between PGIC and PI‐MBS and between PGIC and mean monthly migraine days (MMDs; primary efficacy endpoint in PROMISE‐2). Results Altogether, 1072 patients received treatment (eptinezumab 100 mg, n = 356; eptinezumab 300 mg, n = 350; placebo, n = 366) and were included in the analysis. There were 23 unique MBS identified; those reported by ≥10 patients included light sensitivity (18.7%), nausea/vomiting (15.1%), pain with activity (13.7%), pain (12.4%), headache (11.2%), sound sensitivity (7.3%), throbbing/pulsating pain (4.7%), cognitive disruption (4.1%), fatigue (2.4%), mood changes (1.5%), and sensitivity to smell (0.9%). Four weeks after the first dose (week 4), the rates of much or very much improvement in PI‐MBS were higher with eptinezumab 100 mg (45%) and 300 mg (57%) than with placebo (29%). Four weeks after the second dose (week 16), the proportions with much or very much improvement in PI‐MBS had increased to 58%, 65%, and 36%, respectively. At each time point, the percentages of patients with PGIC ratings of much or very much improved were similar to those for patient‐reported improvement in PI‐MBS. Patient ratings of changes in PI‐MBS and PGIC correlated strongly across time points (Pearson, r range, 0.83–0.88; Spearman, r range, 0.83–0.89); the absolute value of the correlations was greater than the correlation among changes in MMDs and PGIC (Pearson, r range, −0.49 to −0.52; Spearman, r range, −0.49 to −0.52). Conclusions Among patients with CM in the PROMISE‐2 study, a broad range of PI‐MBS was reported at baseline. Throughout the study, patients treated with eptinezumab reported greater improvement in their PI‐MBS severity compared with placebo recipients, and this improvement correlated strongly with PGIC findings. Collectively, these results indicate that PI‐MBS is a promising and novel outcome measure for preventive trials of CM and thus may provide a unique patient‐centered approach for identifying and measuring the burden of migraine symptoms that matter most to each patient, as well as the benefits of treatment.

Abstract Patients with core-binding factor (CBF) acute myeloid leukemia (AML), caused by either t(8;21)(q22;q22) or inv(16)(p13q22)/t(16;16)(p13;q22), have higher complete remission rates and longer survival than patients with other subtypes of AML. However, ∼40% of patients relapse, and the literature suggests that patients with inv(16) fare differently from those with t(8;21). We retrospectively analyzed 537 patients with CBF-AML, focusing on additional cytogenetic aberrations to examine their impact on clinical outcomes. Trisomies of chromosomes 8, 21, or 22 were significantly more common in patients with inv(16)/t(16;16): 16% vs 7%, 6% vs 0%, and 17% vs 0%, respectively. In contrast, del(9q) and loss of a sex chromosome were more frequent in patients with t(8;21): 15% vs 0.4% for del(9q), 37% vs 0% for loss of X in females, and 44% vs 5% for loss of Y in males. Hyperdiploidy was more frequent in patients with inv(16) (25% vs 9%, whereas hypodiploidy was more frequent in patients with t(8;21) (37% vs 3%. In multivariable analyses (adjusted for age, white blood counts at diagnosis, and KIT mutation status), trisomy 8 was associated with improved overall survival (OS) in inv(16), whereas the presence of other chromosomal abnormalities (not trisomy 8) was associated with decreased OS. In patients with t(8;21), hypodiploidy was associated with improved disease-free survival; hyperdiploidy and del(9q) were associated with improved OS. KIT mutation (either positive or not tested, compared with negative) conferred poor prognoses in univariate analysis only in patients with t(8;21).

AbstractBackgroundCheckpoint inhibitors (CPI) in combination with cell‐based vaccines may produce synergistic antitumor immunity. The primary analysis of the randomized and blinded phase IIb trial in resected stage III/IV melanoma demonstrated TLPLDC is safe and improved 24‐month disease‐free survival (DFS) in the per treatment (PT) analysis. Here, we examine efficacy within pre‐specified and exploratory subgroups.MethodsStage III/IV patients rendered disease‐free by surgery were randomized 2:1 to TLPLDC vaccine versus placebo. The pre‐specified PT analysis included only patients completing the primary vaccine/placebo series at 6 months. Kaplan–Meier analysis was used to compare 24‐month DFS among subgroups.ResultsThere were no clinicopathologic differences between subgroups except stage IV patients were more likely to receive CPI. In stage IV patients, 24‐month DFS was 43% for vaccine versus 0% for placebo (p = 0.098) in the ITT analysis and 73% versus 0% (p = 0.002) in the PT analysis. There was no significant difference in 24‐month DFS when stratified by use of immunotherapy or CPI. For patients with resected recurrent disease, 24‐month DFS was 88.9% versus 33.3% (p = 0.013) in the PT analysis. All benefit from vaccination was in the PT analysis; no benefit was found in patients receiving up to three doses.ConclusionThe TLPLDC vaccine improved DFS in patients completing the primary vaccine series, particularly in the resected stage IV patients. The efficacy of the TLPLDC vaccine will be confirmed in a phase III study evaluating adjuvant TLPLDC + CPI versus Placebo + CPI in resected stage IV melanoma patients.

Background: The management of patients with triple-negative breast cancer (TNBC) is challenging with several controversies and unmet needs. During the 12th Breast-Gynaecological & Immuno-oncology International Cancer Conference (BGICC) Egypt, 2020, a panel of 35 breast cancer experts from 13 countries voted on consensus guidelines for the clinical management of TNBC. The consensus was subsequently updated based on the most recent data evolved lately. Methods: A consensus conference approach adapted from the American Society of Clinical Oncology (ASCO) was utilized. The panellists voted anonymously on each question, and a consensus was achieved when ≥75% of voters selected an answer. The final consensus was later circulated to the panellists for critical revision of important intellectual content. Results and conclusion: These recommendations represent the available clinical evidence and expert opinion when evidence is scarce. The percentage of the consensus votes, levels of evidence and grades of recommendation are presented for each statement. The consensus covered all the aspects of TNBC management starting from defining TNBC to the management of metastatic disease and highlighted the rapidly evolving landscape in this field. Consensus was reached in 70% of the statements (35/50). In addition, areas of warranted research were identified to guide future prospective clinical trials.

Abstract Objective: The detection and management of concomitant pheochromocytoma (PHEO) and primary aldosteronism (PA) is not well understood. Our objectives were to investigate varying presentations and outcomes of cases with coexisting PHEO and PA to provide an approach to its diagnosis and management. Design: Retrospective case series from 2000–2020 at a single institution tertiary center; additional review of previously known cases before 2000 and from the medical literature. Patients and Measurements: Adult patients with concomitant PHEO and PA. Clinical, biochemical, radiologic, and histologic parameters were reviewed. Results: Fifteen patients (53% men, median age 53 years) were diagnosed with concomitant PHEO and PA. The majority presented with hypertension (13, 87%) and hypokalemia (13, 87%), but only 6 (40%) presented with symptoms suggestive of catecholamine excess. All patients with preoperative work-up for catecholamine excess (14, 93%) were found to have elevated plasma or urinary metanephrines/catecholamines above the upper limit of normal. Adrenal vein sampling (AVS) was performed in 9 (60%) patients, where 5 (56%) were diagnosed with bilateral PA, and 4 (44%) with unilateral PA. All patients underwent either unilateral (12, 80%) or bilateral (3, 20%) adrenalectomy to treat their PHEO and/or PA. Postoperative catecholamines and/or catecholamine breakdown products normalized or improved in 13 (87%) patients and were not measured in 2. Recurrence of PHEO was not observed. Six (40%) displayed persistent PA postoperatively, where 4 required long-term mineralocorticoid blockade. Conclusions: Concomitant PHEO and PA is a rare but likely under-reported condition. Hypertension with or without hypokalemia should prompt evaluation for PA, while any indeterminate adrenal mass should be worked up for PHEO. Coexisting disease warrants consideration of AVS to determine the laterality of PA to ensure appropriate management.

ObjectiveThis study tested whether substrate concentrations or fatty acid storage proteins predict storage of endogenous lipids in visceral adipose tissue (VAT) and upper body subcutaneous adipose tissue (UBSQ) fat.MethodsThe day prior to surgery, 25 patients undergoing bariatric procedures received an infusion of autologous [1‐14C]triolein‐labeled very low‐density lipoprotein (VLDL) particles, and during surgery, they received a continuous [U‐13C]palmitate infusion/bolus [9,10‐3H]palmitate tracer. VAT and UBSQ fat were collected to measure VLDL‐triglyceride (TG) storage, direct free fatty acid (FFA) storage rates, CD36 content, lipoprotein lipase (LPL), acyl‐CoA synthetase, diacylglycerol acetyl‐transferase, and glycerol‐3‐phosphate acyltransferase activities.ResultsStorage of VLDL‐TG and FFA‐palmitate in UBSQ and VAT was not different. Plasma palmitate concentrations correlated with palmitate storage rates in UBSQ and VAT (r = 0.46, P = 0.02 and r = 0.46, P = 0.02, respectively). In VAT, VLDL‐TG storage was correlated with VLDL concentrations (r = 0.53, P < 0.009) and LPL (r = 0.42, P < 0.05). In UBSQ, VLDL‐TG storage was correlated with LPL (r = 0.42, P < 0.05). CD36, acyl‐CoA synthetase, glycerol‐3‐phosphate acyltransferase, and diacylglycerol acetyl‐transferase were not correlated with VLDL‐TG or palmitate storage.ConclusionsAdipose storage of VLDL‐TG is predicted by VLDL‐TG concentrations and LPL; FFA concentrations predict direct adipose tissue FFA storage rates.

Secretory carcinoma (SC) was first recognized as a distinct salivary malignancy in 2010. In the nine years since its recognition, there have been multiple reports of SC of the major and minor salivary glands, as well one case of tongue base involvement. Here we present the first reported case of bilateral SC. The first tumor, diagnosed before the recognition of SC, was classified as mucoepidermoid carcinoma. After the contralateral parotid tumor was diagnosed as SC in 2016, the two histologies were compared, and the mucoepidermoid carcinoma was reclassified as SC. In this report, we describe our patient’s clinical course and review the SC literature, with a focus on pathologic diagnosis and clinical prognosis.
