A Rare Case of Isolated Cardiac Sarcoidosis With Negative Biopsy: Diagnosis by Clinical Criteria.

Cardiac sarcoidosis (CS) is a potentially life-threatening condition that can cause sudden, fatal conduction abnormalities, arrhythmias, and heart failure. The diagnosis of CS is challenging due to nonspecific symptoms and an unclear diagnostic criterion. Although biopsy is the gold standard method, the sensitivity of biopsy is low. About a portion of CS cases are detected through imaging. A unique aspect of our case is that our definitive diagnosis was made based on clinical and imaging criteria alone despite a negative biopsy. Our diagnosis was confirmed further on follow-up with improvement in cardiac function on imaging after a treatment course with corticosteroids. This case highlights the need to have a broad differential and more awareness of this rare etiology and the value of clinical criteria to make a definitive diagnosis.

Early-Onset Pancreatic Neuroendocrine Tumors: Clinical Presentation, Pathology Features, and Oncological Outcomes.

BACKGROUND: Early-Onset (EO) pancreatic neuroendocrine tumor (PanNET) is a rare disease, but whether it is clinically different from late-onset (LO) PanNET is unknown. Our study aimed to evaluate clinical differences and disease outcomes between EO-PanNET and LO-PanNET and to compare sporadic EO-PanNET with those with a hereditary syndrome. METHODS: Patients with localized PanNET who underwent pancreatectomy at Memorial Sloan Kettering between 2000 and 2017 were identified. Those with metastatic disease and poorly differentiated tumors were excluded. EO-PanNET was defined as <50 and LO-PanNET >50 years of age at the time of diagnosis. Family history and clinical and pathology characteristics were recorded. RESULTS: Overall 383 patients were included, 107 (27.9%) with EO-PanNET. Compared with LO-PanNET, EO-PanNET were more likely to have a hereditary syndrome (2.2% vs. 16%, P <0.001) but had similar pathology features such as tumor grade ( P =0.6), size (2.2 Vs. 2.3 cm, P =0.5) and stageof disease ( P =0.8). Among patients with EO-PanNET, those with hereditary syndrome had more frequently a multifocal disease (65% vs. 3.3%, P <0.001). With a median follow-up of 70 months (range 0-238), the 5-year cumulative incidence of recurrence after curative surgery was 19% (95% CI 12%-28%) and 17% (95% CI 13%-23%), in EO-PanNET and LO-PanNET ( P =0.3). Five-year disease-specific survival was 99% (95% CI 98%-100%) with no difference with respect to PanNET onset time ( P =0.26). CONCLUSIONS: In this surgical cohort, we found that EO-PanNET is associated with hereditary syndromes but has pathologic characteristics and oncological outcomes similar to LO-PanNET. These findings suggest that patients with EO-PanNET can be managed similarly to those with LO-PanNET.

Exploring the "misfolding problem" by systematic discovery and analysis of functional-but-degraded proteins.

In both health and disease, the ubiquitin-proteasome system (UPS) degrades point mutants that retain partial function but have decreased stability compared with their wild-type counterparts. This class of UPS substrate includes routine translational errors and numerous human disease alleles, such as the most common cause of cystic fibrosis, ΔF508-CFTR. Yet, there is no systematic way to discover novel examples of these "minimally misfolded" substrates. To address that shortcoming, we designed a genetic screen to isolate functional-but-degraded point mutants, and we used the screen to study soluble, monomeric proteins with known structures. These simple parent proteins yielded diverse substrates, allowing us to investigate the structural features, cytotoxicity, and small-molecule regulation of minimal misfolding. Our screen can support numerous lines of inquiry, and it provides broad access to a class of poorly understood but biomedically critical quality-control substrates.

Suggestions for modifications to the Female Sexual Function Index based on cognitive interviews with sexual and gender minority individuals and cisgender, heterosexual persons.

BACKGROUND: Patient-reported outcome measures for sexual health were often designed for research studies that included only heterosexual, partnered, and cisgender participants; as such, they may have limited applicability for clinical use among sexual and gender minority (SGM) individuals or those without a partner. AIM: We aimed to conduct cognitive interviews with SGM persons and heterosexual women to determine the readability, comprehension, and applicability of questionnaire items to assess sexual function among diverse sexual and gender identities. METHODS: We conducted 4 rounds of cognitive interviews with 52 participants (28 SGM; 24 cisgender, heterosexual) who provided feedback on the comprehension and wording of questionnaire items and response scales. We used items from the Female Sexual Function Index (FSFI) and focused on establishing content validity of a modified measure. Participants made recommendations for changes to the questionnaire, which was iteratively revised between interview rounds. Two independent coders analyzed the transcripts using structural coding based on 5 predefined codes: satisfaction with item, specificity/language change needed, missing/suggested item, patient definitions of concepts, and confusion with item. OUTCOMES: Content validity. RESULTS: After 3 rounds of cognitive interviews and revisions to the questionnaire, participants found the final version acceptable and understandable, thereby reaching thematic saturation and establishing content validity of the modified FSFI. Modifications included the following: replacing all instances of "sexual stimulation" and "intercourse" with "sexual activity (alone or with a partner)," broadening the definition of "vaginal penetration" beyond penile-vaginal penetration, and adding skip logic to include the option "no sexual activity." Participants identified missing concepts important to their sexual health, such as use of an external lubricant. CLINICAL IMPLICATIONS: The FSFI and similar questionnaires need to be adapted to broader clinical practice populations such that all persons' experiences are accurately reflected and assessed, ensuring that sexual health needs can be met more inclusively. STRENGTH AND LIMITATIONS: A strength of the study was using cognitive interviews engaging patient perspectives, which is considered the gold standard for establishing content validity. One limitation is that participants included predominantly White and highly educated women. CONCLUSION: Feedback from interviews supports modifying FSFI items and further psychometric testing, and future studies should evaluate the measure among racially and educationally diverse groups.

Urinary Neuroendocrine Neoplasms Treated in the "Modern Era": A Multicenter Retrospective Review.

BACKGROUND: Primary urinary neuroendocrine neoplasms (U-NENs) are extremely rare thus optimal treatment is unknown. Grading and treatment are typically extrapolated from other primary sites. Since 2010, the clinical landscape for NENs has changed substantially. We performed a retrospective review of U-NENs to assess treatment patterns and oncologic outcomes of patients treated in the recent era of NEN therapy. PATIENTS AND METHODS: A multicenter retrospective review of patients diagnosed after 2005 and alive after 2010. Time to treatment failure (TTF) was used to evaluate progression and toxicity for systemic therapy. Tumors were categorized as having either well-differentiated neuroendocrine tumor (WDNET) or poorly differentiated neuroendocrine carcinoma (PDNEC) histology. RESULTS: A total of 134 patients from 6 centers were included in our analysis, including 94 (70%) bladder, 32 (24%) kidney, 2 (1.5%) urethra and 4 other urinary primaries (3.0%). Poorly-differentiated neuroendocrine carcinoma was more common in bladder (92%) than non-bladder tumors (8%). Median Ki-67 available in bladder primary was 90% (n = 24), kidney 10% (n = 23), ureter 95% (n = 1), urethra 54% (n = 2), and others 90% (n = 3). Patients received a median of 2 therapies (range 0-10). Median time to death was not reached in locoregional WDNETs versus 8.2 years (95% CI, 3.5-noncalculable) in metastatic WDNETs (predominantly renal primary). Median time to death was 3.6 years (95% CI, 2.2-9.2) in locoregional PDNECs versus 1 year (95% CI, 0.8-1.3) in metastatic PDNECs (predominantly bladder primary). CONCLUSION: This is the most extensive series examining treatment patterns in patients with U-NENs in the recent era of NEN therapy. The apparent inferior survival for bladder NENs is likely due to the preponderance of PDNECs in this group. As predicted, treatments for U-NENs mirrored that of other more common NENs. In our retrospective cohort, we observed that patients with WD-UNETs treated with peptide receptor radionuclide therapy (PRRT) and everolimus suggested potential activity for disease control in WD-UNETs. Prospective studies are needed to assess the activity of new oncology drugs in UNENs.

Patient Perceptions of a Decision Support Tool for Men with Localized Prostate Cancer.

Purpose. To evaluate patient perceptions of a Web-based decision aid for the treatment of localized prostate cancer. Methods. We assessed patient perceptions of a multicomponent, Web-based decision aid with a preference elicitation/values clarification exercise using adaptive conjoint analysis, the generation of a summary report, and provision of information about localized prostate cancer treatment options. Using a think-aloud approach, we conducted 21 cognitive interviews with prostate cancer patients presented with the decision aid prior to seeing their urologist. Thematic content analysis was used to examine patient perceptions of the tool's components and content prior to engaging in shared decision making with their clinician. Results. Five themes were identified: 1) patients had some negative emotional reactions to the tool, pointing out what they perceived to be unnecessarily negative framing and language used; 2) patients were forced to stop and think about preferences while going through the tool and found this deliberation to be useful; 3) patients were confused by the tool; 4) patients tried to discern the intent of the conjoint analysis questions; and 5) there was a disconnect between patients' negative reactions while using the tool and a contrasting general satisfaction with the final "values profile" created by the tool. Conclusions. Studies are needed to explore the disconnect between patients' expressing negative reactions while going through some components of decision aids but satisfaction with the final output. In particular, we hypothesize that this effect might be explained by cognitive biases such as choice-supportive bias, hindsight bias, and the "IKEA effect." This is one of the first projects to elicit patient reactions while they were completing a decision aid, and we recommend further similar, qualitative postprocess evaluation studies. Highlights: We explored perceptions of a decision aid with education about localized prostate cancer treatment and preference elicitation using adaptive conjoint analysis.Patients found the tool useful but were also confused by it, tried to discern the intent of the questions, and expressed negative emotional reactions.In particular, there was a disconnect between patients' negative reactions while using the tool and general satisfaction with the final values profile generated by the tool, which is an area for future research.

A Randomized Trial Evaluating Patient Experience and Preference Between Octreotide Long-Acting Release and Lanreotide for Treatment of Well-Differentiated Neuroendocrine Tumors.

PURPOSE: Somatostatin analogs octreotide long-acting release (octLAR) and lanreotide are equally acceptable in National Comprehensive Cancer Network guidelines for neuroendocrine tumors (NETs). Lanreotide is more expensive and given by deep subcutaneous injection, whereas octLAR is given intramuscularly. We evaluated patient preference between these agents in terms of injection site pain. MATERIALS AND METHODS: Randomized, single-blinded study. Patients with NETs received injections every 4 weeks. Arm 1: octLAR × 3, then lanreotide × 3; arm 2: reverse order. Self-reported injection site pain scores (range, 0-10) were obtained after each of the first three injections. Primary end point was comparison of mean pain scores over the first three injections. Secondary end points included patient-reported preference. RESULTS: Fifty-one patients enrolled (26 in arm 1 and 25 arm 2), all evaluable for primary end point. No significant difference was identified in the mean pain score over the first three injections (2.4 ± 1.9 v 1.9 ± 1.5, P = .5). Thirty-four of 51 (67%) patients (15 in arm 1 and 19 in arm 2) completed post-therapy questionnaires and were evaluable for secondary end points. Seven patients (47%) in arm 1 and eight patients (42%) in arm 2 indicated no drug preference at the end of treatment. In the other 19 patients, more patients indicated mild or strong preference for octLAR over lanreotide. CONCLUSION: We found minimal pain with octLAR and lanreotide and no significant pain score differences between the two. Patients indicating a drug preference trended toward favoring octLAR.

Randomized Controlled Trial of Health Coaching for Parents of Children With Medical Complexity.

BACKGROUND AND OBJECTIVE: Parents of children with medical complexity (CMCs) struggle with managing their children's care needs. Health coaching provides patients with tools to take ownership of their care. We sought to assess the impact of health coaching for parents of CMCs on activation, child's health related quality of life (HRQL), and utilization. METHODS: Parents of CMCs receiving primary care at two academic primary care practices were randomized to receive 3-6 months of coaching from a trained health coach (n = 54) or usual care (n = 71). Parents were surveyed on activation, HRQL, and experience of care at baseline and the end of the study period. Markers of utilization (missed visit rates, ED, and admissions) were measured for 12 months prior to and after enrollment. Parametric, nonparametric, and Poisson regression were used to assess baseline differences in characteristics and average pre-post differences between the groups. RESULTS: At baseline, activation and rating of patient experience were high in both groups, while HRQL was one standard deviation below the population-based mean. Both groups had slight increases in HRQL and P-PAM without significant differences between groups. ED visits declined significantly more in the intervention group than the usual care group (0.68 visits, (-0.03, -1.32) P = .04); there were nonsignificant differences in changes in other utilization metrics. CONCLUSION: Health coaching was associated with a decrease in ED use but not in changes in activation, patient experience, or HRQL. More inquiry is needed to understand whether health coaching is an effective modality for improving care for children with medical complexity.

Treatment Response and Clinical Outcomes of Well-Differentiated High-Grade Neuroendocrine Tumors to Lutetium-177-DOTATATE.

INTRODUCTION: Lutetium-177 (177Lu)-DOTATATE received FDA approval in 2018 to treat somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (NETs). Little data are available on response and outcomes for well-differentiated (WD) high-grade (HG) NETs treated with 177Lu-DOTATATE. MATERIALS AND METHODS: Patients with WD HG NETs treated with 177Lu-DOTATATE at MSK from 2018 to 2020 were identified. Demographics, response (RECIST 1.1), and progression-free survival (PFS) were determined. Next-generation sequencing (NGS) was performed in the archival tumor. RESULTS: Nineteen patients, all with progressive, heavily treated disease, were identified. Sites of tumor origin were: pancreas (74%), small bowel (11%), rectum (11%), and lung (5%); median Ki-67 was 32% (range 22-56). Thirteen patients (68%) completed all four 177Lu-DOTATATE cycles. Best response (N = 18 evaluable) was: 5/18 (28%) partial response, 8/18 (44%) stable disease, and 5/18 (28%) disease progression. Median PFS was 13.1 months (95% CI: 8.7-20.9). Most common treatment-related toxicities were thrombocytopenia (9 patients, 47%; G3/4, 1 patient, 5%), anemia (7 patients, 37%; G3/4, 2 patients, 11%), leukopenia (6 patients, 32%; G3/4, 0 patients), and liver function test elevation (4 patients, 21%; G3/4, 0 patients). NGS results were available from 13/19 tumors (68%). The most observed alterations were in MEN1 (6/13, 46%) and DAXX (4/13, 31%). No RB1 alterations identified. CONCLUSION: We observed a meaningful disease control rate of 72% during treatment of WD HG NETs with 177Lu-DOTATATE. In this heavily pre-treated population, more than half of patients received all four treatment cycles with toxicities largely bone marrow-related. As would be expected in WD NETs, the vast majority had alterations in chromatin remodeling genes and no RB1 alterations.

Understanding Caregiver Perspectives on an Electronic Consultation and Referral System.

This study examined caregiver impressions of an electronic consultation and referral (ECR) system. Participants included 56 caregivers of primary care patients referred through the ECR system. Semistructured interviews and surveys were conducted between August 2018 and April 2019. Transcripts were coded and themes developed using thematic content analysis. A total of 51% of caregivers stated that they would prefer to see their child's primary care provider (PCP) for a specialty issue if they could receive the same quality of care. All caregivers who received an electronic consult (n = 28) said that they would utilize that process again. Three themes emerged: (1) caregivers expect immediate action prior to or instead of a specialty referral; (2) caregiver preferences for PCP versus specialist are mediated by both child and provider characteristics; (3) caregiver attitudes toward the ECR system are influenced by external considerations and experiences with the system. Results suggest caregivers value enhanced communication and immediate access to specialty input facilitated by the ECR system.

Sexual and Gender Minority Persons' Perception of the Female Sexual Function Index.

BACKGROUND: Patient-reported outcome instruments to assess sexual functioning typically assume that patients are heterosexual and have a single sexual partner, thus they may have limited applicability for sexual and gender minority (SGM) populations as well as for nonpartnered individuals or those with multiple partners. AIM: To explore the perceptions of SGM persons regarding the Female Sexual Function Index (FSFI), a commonly used sexual functioning questionnaire. METHODS: We conducted 2 rounds of cognitive interviews with 27 SGM persons with and without a cancer diagnosis. Interviews were audio-recorded and transcribed. Two researchers independently coded the transcripts using inductive thematic analysis to identify major themes. OUTCOMES: Themes identified via qualitative analysis. RESULTS: Cognitive debriefing with the participants provided critical insights about the way we ask questions about sexual functioning in the oncology clinic. Three overarching themes arose from the data: (i) Certain aspects of the questionnaire were felt to unnecessarily medicalize sexuality; (ii) FSFI domains were perceived to represent a narrow and heteronormative experience of sexuality focused on penile-vaginal intercourse; (iii) Questionnaire domains emphasizing sexual "performance" were perceived as male-oriented. CLINICAL IMPLICATIONS: Questionnaires such as the FSFI that were developed in research studies with specific eligibility criteria need to be adapted to the broader population seen in clinical practice. STRENGTHS & LIMITATIONS: Strengths of the study include purposive sampling of SGM persons through LGBTQ networks. Our sample included individuals of different sexual orientations, gender identities, marital status, and cancer histories. However, a limitation is that the the majority of the sample was white and college-educated. Other limitations of the study include the potential sampling bias of self-selected participants with a particular interest in the study questions. CONCLUSION: The findings provide important evidence for the development of a more inclusive sexual function measure, moving away from the traditional heteronormative, cisnormative approach to measuring sexual function.

Socio-demographic factors related to parent engagement in the NICU and the impact of the SENSE program.

BACKGROUND: Early parent engagement in the neonatal intensive care unit (NICU) is important for both parent and infant mental health and for improving developmental outcomes. It remains unclear how different programs, such as the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, may empower parents from various socio-demographic groups to engage in the NICU. An improved understanding could aid in individualizing interventions for those at the highest risk for health disparities. AIMS: This exploratory study, which was part of a larger study, sought to explore 1) socio-demographic factors related to parent presence and engagement in the NICU and 2) if the SENSE program related to increased parent presence and engagement among different socio-demographic groups. METHODS: Seventy parent-infant dyads (born ≤ 32 weeks gestation) were randomized to SENSE programming (parent education and age-appropriate, positive sensory interventions for parents to conduct with their infants every day of hospitalization) or standard care after admission to the NICU. The amount of parent presence and participation in sensory activities was tracked using bedside logs, nursing records, and research team documentation. RESULTS: Being married (p = 0.048; p = 0.01), having private insurance (p < 0.001; p = 0.01), and having fewer children (p = 0.004; p = 0.03) related to more parent presence and engagement respectively. Parents who were Black had less presence and engagement in the NICU (p = 0.04; p = 0.02). Participation in the SENSE program was related to more parent presence and engagement among younger mothers (p = 0.002; p ≤0.001) and among parents living farther distances from the hospital (p < 0.001; p = 0.004). CONCLUSION: Programming, such as the SENSE program, can improve parent engagement in the NICU among high-risk groups.

Prospective study to define the clinical utility and benefit of Decipher testing in men following prostatectomy.

BACKGROUND: Genomic classifiers (GC) have been shown to improve risk stratification post prostatectomy. However, their clinical benefit has not been prospectively demonstrated. We sought to determine the impact of GC testing on postoperative management in men with prostate cancer post prostatectomy. METHODS: Two prospective registries of prostate cancer patients treated between 2014 and 2019 were included. All men underwent Decipher tumor testing for adverse features post prostatectomy (Decipher Biosciences, San Diego, CA). The clinical utility cohort, which measured the change in treatment decision-making, captured pre- and postgenomic treatment recommendations from urologists across diverse practice settings (n = 3455). The clinical benefit cohort, which examined the difference in outcome, was from a single academic institution whose tumor board predefined "best practices" based on GC results (n = 135). RESULTS: In the clinical utility cohort, providers' recommendations pregenomic testing were primarily observation (69%). GC testing changed recommendations for 39% of patients, translating to a number needed to test of 3 to change one treatment decision. In the clinical benefit cohort, 61% of patients had genomic high-risk tumors; those who received the recommended adjuvant radiation therapy (ART) had 2-year PSA recurrence of 3 vs. 25% for those who did not (HR 0.1 [95% CI 0.0-0.6], p = 0.013). For the genomic low/intermediate-risk patients, 93% followed recommendations for observation, with similar 2-year PSA recurrence rates compared with those who received ART (p = 0.93). CONCLUSIONS: The use of GC substantially altered treatment decision-making, with a number needed to test of only 3. Implementing best practices to routinely recommend ART for genomic-high patients led to larger than expected improvements in early biochemical endpoints, without jeopardizing outcomes for genomic-low/intermediate-risk patients.

Tyrosine hydroxylase and regulation of dopamine synthesis.

Tyrosine hydroxylase is the rate-limiting enzyme of catecholamine biosynthesis; it uses tetrahydrobiopterin and molecular oxygen to convert tyrosine to DOPA. Its amino terminal 150 amino acids comprise a domain whose structure is involved in regulating the enzyme's activity. Modes of regulation include phosphorylation by multiple kinases at four different serine residues, and dephosphorylation by two phosphatases. The enzyme is inhibited in feedback fashion by the catecholamine neurotransmitters. Dopamine binds to TyrH competitively with tetrahydrobiopterin, and interacts with the R domain. TyrH activity is modulated by protein-protein interactions with enzymes in the same pathway or the tetrahydrobiopterin pathway, structural proteins considered to be chaperones that mediate the neuron's oxidative state, and the protein that transfers dopamine into secretory vesicles. TyrH is modified in the presence of NO, resulting in nitration of tyrosine residues and the glutathionylation of cysteine residues.
