AbstractCancer and its treatment produce deleterious symptoms across the phases of care. Poorly controlled symptoms negatively affect quality of life and result in increased health-care needs and hospitalization. The Improving the Management of symPtoms during And following Cancer Treatment (IMPACT) Consortium was created to develop 3 large-scale, systematic symptom management systems, deployed through electronic health record platforms, and to test them in pragmatic, randomized, hybrid effectiveness and implementation trials. Here, we describe the IMPACT Consortium’s conceptual framework, its organizational components, and plans for evaluation. The study designs and lessons learned are highlighted in the context of disruptions related to the COVID-19 pandemic.

Objectives: Sensorineural hearing loss (SNHL) occurs commonly as part of mitochondriopathies and varies in severity and onset. In this study, we characterized hearing with specific consideration for hearing loss as a potential early indicator of mitochondrial disease (MD). We hypothesize that genetic testing at the earliest detection of SNHL may lead to an earlier MD diagnosis. Design: We reviewed the clinical and audiometric data of 49 patients undergoing genetic testing for MD. Results: One-third of individuals with molecularly confirmed MD presented with SNHL. On average, patients had hearing loss at least 10 years before genetic testing. The collective audiometric profile includes mild to moderate SNHL at lower frequencies and moderate SNHL at 2 kHz and higher frequencies. Conclusions: This study suggests that screening for SNHL could be an early indicator of MD. We propose that the audiometric profile for those with a MD diagnosis may have clinical triage utility.

AbstractPeripheral T‐cell lymphoma (PTCL) is a clinically heterogeneous group that represents 10%–15% of all lymphomas. Despite improved genetic and molecular understanding, treatment outcomes for PTCL have not shown significant improvement. Although Janus kinase‐2 (JAK2) plays an important role in myeloproliferative neoplasms, the critical role of JAK isoforms in mediating prosurvival signaling in PTCL cells is not well defined. Immunohistochemical analysis of PTCL tumors (n = 96) revealed high levels of constitutively active JAK3 (pJAK3) that significantly (p < 0.04) correlated with the activation state of its canonical substrate STAT3. Furthermore, constitutive activation of JAK3 and STAT3 positively correlated, at least in part, with an oncogenic tyrosine phosphatase PTPN11. Pharmacological inhibition of JAK3 but not JAK1/JAK2 significantly (p < 0.001) decreased PTCL proliferation, survival and STAT3 activation. A sharp contrast was observed in the pJAK3 positivity between ALK+ (85.7%) versus ALK‐negative (10.0%) in human PTCL tumors and PTCL cell lines. Moreover, JAK3 and ALK reciprocally interacted in PTCL cells, forming a complex to possibly regulate STAT3 signaling. Finally, combined inhibition of JAK3 (by WHI‐P154) and ALK (by crizotinib or alectinib) significantly (p < 0.01) decreased the survival of PTCL cells as compared to either agent alone by inhibiting STAT3 downstream signaling. Collectively, our findings establish that JAK3 is a therapeutic target for a subset of PTCL, and provide rationale for the clinical evaluation of JAK3 inhibitors combined with ALK‐targeted therapy in PTCL.

Objective The objective of the current study was to present the results of an international working group survey identifying perceived limitations of existing facial nerve grading scales to inform the development of a novel grading scale for assessing early postoperative facial paralysis that incorporates regional scoring and is anchored in recovery prognosis and risk of associated complications. Study Design Survey. Setting A working group of 48 multidisciplinary clinicians with expertise in skull base, cerebellopontine angle, temporal bone, or parotid gland surgery. Results House-Brackmann grade is the most widely used system to assess facial nerve function among working group members (81%), although more than half (54%) agreed that the system they currently use does not adequately estimate the risk of associated complications, such as corneal injury, and confidence in interrater and intrarater reliability is generally low. Simplicity was ranked as the most important attribute of a novel postoperative facial nerve grading system to increase the likelihood of adoption, followed by reliability and accuracy. There was widespread consensus (91%) that the eye is the most critical facial region to focus on in the early postoperative setting. Conclusions Members were invited to submit proposed grading systems in alignment with the objectives of the working group for subsequent validation. From these data, we plan to develop a simple, clinically anchored, and reproducible staging system with regional scoring for assessing early postoperative facial nerve function after surgery of the skull base, cerebellopontine angle, temporal bone, or parotid gland.

Background: Limited information is available for patients with breast cancer (BC) and coronavirus disease 2019 (COVID-19), especially among underrepresented racial/ethnic populations. Methods: This is a COVID-19 and Cancer Consortium (CCC19) registry-based retrospective cohort study of females with active or history of BC and laboratory-confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection diagnosed between March 2020 and June 2021 in the US. Primary outcome was COVID-19 severity measured on a five-level ordinal scale, including none of the following complications, hospitalization, intensive care unit admission, mechanical ventilation, and all-cause mortality. Multivariable ordinal logistic regression model identified characteristics associated with COVID-19 severity. Results: 1383 female patient records with BC and COVID-19 were included in the analysis, the median age was 61 years, and median follow-up was 90 days. Multivariable analysis revealed higher odds of COVID-19 severity for older age (aOR per decade, 1.48 [95% CI, 1.32–1.67]); Black patients (aOR 1.74; 95 CI 1.24–2.45), Asian Americans and Pacific Islander patients (aOR 3.40; 95 CI 1.70–6.79) and Other (aOR 2.97; 95 CI 1.71–5.17) racial/ethnic groups; worse ECOG performance status (ECOG PS ≥2: aOR, 7.78 [95% CI, 4.83–12.5]); pre-existing cardiovascular (aOR, 2.26 [95% CI, 1.63–3.15])/pulmonary comorbidities (aOR, 1.65 [95% CI, 1.20–2.29]); diabetes mellitus (aOR, 2.25 [95% CI, 1.66–3.04]); and active and progressing cancer (aOR, 12.5 [95% CI, 6.89–22.6]). Hispanic ethnicity, timing, and type of anti-cancer therapy modalities were not significantly associated with worse COVID-19 outcomes. The total all-cause mortality and hospitalization rate for the entire cohort was 9% and 37%, respectively however, it varied according to the BC disease status. Conclusions: Using one of the largest registries on cancer and COVID-19, we identified patient and BC-related factors associated with worse COVID-19 outcomes. After adjusting for baseline characteristics, underrepresented racial/ethnic patients experienced worse outcomes compared to non-Hispanic White patients.

ImportanceTracheotomies are frequently performed by nonotolaryngology services. The factors that determine which specialty performs the procedure are not defined in the literature but may be influenced by tracheotomy approach (open vs percutaneous) and other clinicodemographic factors.ObjectiveTo evaluate demographic and clinical characteristics associated with tracheotomies performed by otolaryngologists compared with other specialists and to differentiate those factors from factors associated with use of open vs percutaneous tracheotomy.Design, Setting, and ParticipantsThis multicenter, retrospective cohort study included patients aged 18 years or older who underwent a tracheotomy for cardiopulmonary failure at 1 of 8 US academic institutions between January 1, 2013, and December 31, 2016. Data were analyzed from September 2022 to July 2023.ExposureTracheotomy.Main Outcomes and MeasuresThe primary outcome was factors associated with an otolaryngologist performing tracheotomy. The secondary outcome was factors associated with use of the open tracheotomy technique.ResultsA total of 2929 patients (mean [SD] age, 57.2 [17.2] years; 1751 [59.8%] male) who received a tracheotomy for cardiopulmonary failure (652 [22.3%] performed by otolaryngologists and 2277 [77.7%] by another service) were analyzed. Although 1664 of all tracheotomies (56.8%) were performed by an open approach, only 602 open tracheotomies (36.2%) were performed by otolaryngologists. Most tracheotomies performed by otolaryngologists (602 of 652 [92.3%]) used the open technique. Multivariable regression analysis revealed that self-reported Black race (odds ratio [OR], 1.89; 95% CI, 1.52-2.35), history of neck surgery (OR, 2.71; 95% CI, 2.06-3.57), antiplatelet and/or anticoagulation therapy (OR, 1.74; 95% CI, 1.29-2.36), and morbid obesity (OR, 1.54; 95% CI, 1.24-1.92) were associated with greater odds of an otolaryngologist performing tracheotomy. In contrast, history of neck surgery (OR, 1.36; 95% CI, 0.96-1.92), antiplatelet and/or anticoagulation therapy (OR, 0.80; 95% CI, 0.56-1.14), and morbid obesity (OR, 0.94; 95% CI, 0.74-1.19) were not associated with undergoing open tracheotomy when performed by any service, and Black race (OR, 0.56; 95% CI, 0.44-0.71) was associated with lesser odds of an open approach being used. Age-adjusted Charlson Comorbidity Index score greater than 4 was associated with greater odds of both an otolaryngologist performing tracheotomy (OR, 1.26; 95% CI, 1.03-1.53) and use of the open tracheotomy technique (OR, 1.48, 95% CI, 1.21-1.82).Conclusions and RelevanceIn this study, otolaryngologists were significantly more likely than other specialists to perform a tracheotomy for patients with history of neck surgery, morbid obesity, and ongoing anticoagulation therapy. These findings suggest that patients undergoing tracheotomy performed by an otolaryngologist are more likely to present with complex and challenging clinical characteristics.

Abstract Prior to the 1970s, blending food and liquids and putting them through an enteral access device (EAD) was the most common form of enteral nutrition (EN). However, in the 1970s, blenderized tube feedings (BTFs) became less popular due to the emergence of modern commercial enteral formulas (CEFs). Recently, a cultural shift toward consuming a natural diet, consisting of whole foods, has led to a resurgence in the use of BTF. The increasing use of BTF in a variety of patient care settings identifies a need for practice recommendations that provide guidance for nutrition professionals and patients. Members of the American Society for Parental and Enteral Nutrition (ASPEN) Enteral Nutrition Committee identified salient clinical questions concerning BTF, conducted a comprehensive literature search, and subsequently developed practice recommendations pertaining to the use of BTF. This paper was approved by the ASPEN 2022–2023 Board of Directors.

Abstract Histone H3 lysine 9 methylation (H3K9me), which is written by the Euchromatic Histone Lysine Methyltransferases EHMT1 and EHMT2 and read by the heterochromatin protein 1 (HP1) chromobox (CBX) protein family, is dysregulated in many types of cancers. Approaches to inhibit regulators of this pathway are currently being evaluated for therapeutic purposes. Thus, knowledge of the complexes supporting the function of these writers and readers during the process of cell proliferation is critical for our understanding of their role in carcinogenesis. Here, we immunopurified each of these proteins and used mass spectrometry to define their associated non-histone proteins, individually and at two different phases of the cell cycle, namely G1/S and G2/M. Our findings identify novel binding proteins for these writers and readers, as well as corroborate known interactors, to show the formation of distinct protein complex networks in a cell cycle phase-specific manner. Furthermore, there is an organizational switch between cell cycle phases for interactions among specific writer–reader pairs. Through a multi-tiered bioinformatics-based approach, we reveal that many interacting proteins exhibit histone mimicry, based on an H3K9-like linear motif. Gene ontology analyses, pathway enrichment, and network reconstruction inferred that these comprehensive EHMT and CBX-associated interacting protein networks participate in various functions, including transcription, DNA repair, splicing, and membrane disassembly. Combined, our data reveals novel complexes that provide insight into key functions of cell cycle-associated epigenomic processes that are highly relevant for better understanding these chromatin-modifying proteins during cell cycle and carcinogenesis.

ImportanceLimited literature exists on surgical outcomes after selective deep lobe parotidectomy (SDLP) with preservation of superficial lobe for patients with benign deep lobe tumors.ObjectiveTo compare the following factors for SDLP vs total parotidectomy for patients with benign tumors in the deep lobe: postoperative complications, including facial nerve paresis or paralysis, Frey syndrome, first bite syndrome, cosmetic defect, sialocele formation, and wound infection; and tumor control and recurrence.Design, Setting, and ParticipantsThis case series included 273 adults who underwent SDLP (n = 177) or total parotidectomy (n = 96) at a single tertiary care institution for benign parotid tumors located in the deep lobe or deep lobe and parapharynx from January 1, 2000, to December 31, 2020.ExposureSelective deep lobe parotidectomy vs total parotidectomy.Main Outcomes and MeasuresIncidence of postoperative complications and tumor recurrence.ResultsAmong 273 patients (SDLP, 177 [65%]; 122 women [69%]; median age at surgery, 58 years [IQR, 46-67 years]; total parotidectomy, 96 [35%]; 57 women [59%]; median age at surgery, 59 years [IQR, 40-68 years]), the most common tumor was pleomorphic adenoma (SDLP, 128 of 177 [72%]; total parotidectomy, 62 of 96 [65%]). An abdominal dermal fat graft was less commonly performed for patients who underwent SDLP than those who underwent total parotidectomy (2 of 177 [1%] vs 20 of 96 [21%]; difference, −20% [95% CI, −28% to −11%]). The rate of great auricular nerve preservation was higher in the SDLP group than in the total parotidectomy group (84 of 102 [82%] vs 20 of 34 [59%]; difference, 24% [95% CI, 5%-42%]). No meaningful difference in length of hospital stay was found. The percentage of patients with House-Brackmann grade I immediately after surgery was 48% (85 of 177) in the SDLP group and 21% (20 of 96) in the total parotidectomy group (difference, 28% [95% CI, 16%-40%]). There were no clinically meaningful differences in rates of hematoma, sialocele, seroma, ear numbness, wound infection, or unplanned return to emergency department or operating room. The SDLP group reported a lower rate of Frey syndrome than the total parotidectomy group (1 of 137 [1%] vs 12 of 78 [15%]; difference, −15% [95% CI, −23% to −7%]), as well as a lower rate of facial contour defect (28 of 162 [17%] vs 25 of 84 [30%]; difference, −13% [95% CI, −24% to −1%]) and a higher rate of first bite syndrome (34 of 148 [23%] vs 7 of 78 [9%]; difference, 14% [95% CI, 5%-23%]). The percentage of patients with House-Brackmann grade I at their first follow-up visit was 67% (118 of 177) in the SDLP group compared with 49% (47 of 96) in the total parotidectomy group (difference, 17% [95% CI, 4%-30%]). There was no clinically meaningful difference in House-Brackmann grade after 1 year.Conclusions and RelevanceFindings of this case series study suggest that SDLP can be considered an effective and even superior technique for management of benign tumors in the deep parotid lobe. Advantages associated with SDLP include reduction in need for reconstruction for facial contour defect and reduction in complications, such as immediate facial nerve weakness and Frey syndrome. The incidence of first bite syndrome was higher in the SDLP group. Tumor control was not compromised by SLDP.
