RESUMO

BACKGROUND: High-intensity interval training (HIT) can provide physiologic benefits and may improve postoperative recovery but has not been evaluated in inpatients. This study aimed to evaluate the safety and tolerability of HIT after major surgery. METHODS: We performed a phase I randomized study comparing HIT with low-intensity continuous ambulation (40 m) during the initial inpatient stay after major surgery at a large academic center. Clinicopathologic and pre- and post-exercise physiologic data were captured. Perceived exertion was measured throughout the intervention. RESULTS: Twenty-two subjects were enrolled and randomized with 90% (20 subjects, 10 per arm) completing all aspects of the study. One patient declined participation in the exercise intervention. The HIT and continuous ambulation groups were relatively similar in terms of median age (65.5 vs 63.5), female sex (20% vs 40%), White race (90% vs 90%), having a cancer diagnosis (100% vs 80%), undergoing gastrointestinal surgery (60% vs 80%), median Karnofsky score (60 vs 60), and ability to independently ambulate preoperatively (100% vs 90%). All subjects completed the exercise without protocol deviation, cohort crossover, or safety events. Compared with the continuous ambulation group, the HIT group had higher end median perceived exertion (5.0 [IQR, 5.5] vs 3.0 [IQR, 1.8]), shorter overall time to complete assigned exercise (56.6 seconds vs 91.8 seconds), and a trend toward higher median gait speed over 40 m (0.71 m/s vs 0.44 m/s, P = .126). CONCLUSION: HIT in the hospitalized postoperative patient is safe and may be implemented to help promote positive physiologic outcomes and recovery.

RESUMO

IMPORTANCE: Streptococcus pneumoniae (Spn) colonizes the lungs, killing millions every year. During its metabolism, Spn produces abundant amounts of hydrogen peroxide. When produced in the lung parenchyma, Spn-hydrogen peroxide (H2O2) causes the death of lung cells, and details of the mechanism are studied here. We found that Spn-H2O2 targets intracellular proteins, resulting in the contraction of the cell cytoskeleton and disruption of mitochondrial function, ultimately contributing to cell death. Intracellular proteins targeted by Spn-H2O2 included cytochrome c and, surprisingly, a protein of the cell cytoskeleton, beta-tubulin. To study the details of oxidative reactions, we used, as a surrogate model, the oxidation of another hemoprotein, hemoglobin. Using the surrogate model, we specifically identified a highly reactive radical whose creation was catalyzed by Spn-H2O2. In sum, we demonstrated that the oxidation of intracellular targets by Spn-H2O2 plays an important role in the cytotoxicity caused by Spn, thus providing new targets for interventions.

RESUMO

Streptococcus pneumoniae (Spn) causes pneumonia that kills millions through acute toxicity and invasion of the lung parenchyma. During aerobic respiration, Spn releases hydrogen peroxide (Spn-H 2 O 2 ), as a by-product of enzymes SpxB and LctO, and causes cell death with signs of both apoptosis and pyroptosis by oxidizing unknown cell targets. Hemoproteins are molecules essential for life and prone to oxidation by H 2 O 2 . We recently demonstrated that during infection-mimicking conditions, Spn-H 2 O 2 oxidizes the hemoprotein hemoglobin (Hb), releasing toxic heme. In this study, we investigated details of the molecular mechanism(s) by which the oxidation of hemoproteins by Spn-H 2 O 2 causes human lung cell death. Spn strains, but not H 2 O 2 -deficient SpnΔ spxB Δ lctO strains caused time-dependent cell cytotoxicity characterized by the rearrangement of the actin, the loss of the microtubule cytoskeleton and nuclear contraction. Disruption of the cell cytoskeleton correlated with the presence of invasive pneumococci and an increase of intracellular reactive oxygen species. In cell culture, the oxidation of Hb or cytochrome c (Cyt c ) caused DNA degradation and mitochondrial dysfunction from inhibition of complex I-driven respiration, which was cytotoxic to human alveolar cells. Oxidation of hemoproteins resulted in the creation of a radical, which was identified as a protein derived side chain tyrosyl radical by using electron paramagnetic resonance (EPR). Thus, we demonstrate that Spn invades lung cells, releasing H 2 O 2 that oxidizes hemoproteins, including Cyt c , catalyzing the formation of a tyrosyl side chain radical on Hb and causing mitochondrial disruption, that ultimately leads to the collapse of the cell cytoskeleton.

RESUMO

OBJECTIVE: Airway stenosis-particularly multi-level-presents complex management challenges. This study assessed rates of tracheostomy, decannulation, and the number of surgeries required in patients with posterior glottic stenosis (PGS), multi-level airway stenosis (MLAS), and bilateral vocal fold paralysis (BVFP). METHODS: Airway stenosis patients treated between 2016 and 2021 at three tertiary medical centers were identified. Demographics, etiology of stenosis, medical comorbidities, and patient-reported outcome measures (PROMs) were collected. RESULTS: 158 patients (84 women, mean age 56.98 ± 15.5 years) were identified (54 PGS, 38 MLAS, and 66 BVFP). 72.3% required tracheostomy, including 72.2%, 86.8%, and 63.6% in these groups, respectively. Decannulation rates were 43.6%, 21.2%, and 32.5% in these groups, respectively. Patients with MLAS had higher rates of tracheostomy than BVFP (p < 0.05). However, decannulation rates were not different between groups (p > 0.05). MLAS required more surgeries (mean 4.0 ± 3.9) than PGS (2.4 ± 2.2, p = 0.02) or BVFP (1.0 ± 1.8, p < 0.0001). Mean PROMs scores at the latest follow-up were abnormal: 15.4 ± 12.2 (Dyspnea Index), 19.9 ± 12.2 (Voice Handicap Index-10), and 9.67 ± 11.1 (Eating Assessment Tool-10). Co-morbidities present included body mass index >30 (41.4%), diabetes (31.8%), pulmonary disease (50.7%), gastroesophageal reflux disease (39.4%), autoimmune disease (22.9%), and tobacco use history (55.2%). CONCLUSIONS: Airway stenosis is a challenging clinical problem that negatively impacts patients' quality of life and often requires numerous surgeries. PGS more frequently requires tracheostomy compared to BVFP, but patients can often decannulate successfully. Patients with multi-level stenosis have lower decannulation rates and require more surgeries than glottic stenosis alone; these patients may benefit from earlier and/or more aggressive intervention.

RESUMO

OBJECTIVES: The objective of this study was to examine the types of accounts that create posts related to laryngology on Instagram, using hashtags derived from common diagnoses and procedures within the field, in order to assess the source and ownership of laryngology social media discussions. METHODS: Fellowship-trained laryngologists were surveyed to determine the most common diagnoses treated and procedures performed in laryngology. These terms were then queried as hashtags on Instagram. The top 15 posts found per hashtag were classified by the category of individual who shared the content. The categories included laryngologists/otolaryngologists, speech-language pathologists (SLP), vocalists, other physicians, and "other individuals." RESULTS: After surveying 20 fellowship-trained laryngologists, 25 different hashtags related to common diagnoses and procedures in laryngology were created and queried for the top 15 posts on Instagram. 260 posts on Instagram were identified, out of which 30.8% were posted by laryngologists/otolaryngologists, 19.2% by SLPs, 3.1% by vocalists, 6.1% by other physicians, and 40.8% by "other individuals." CONCLUSIONS: A significant portion of top resulted posts on Instagram sharing laryngology-related content is not posted by laryngologists. This raises an issue of the reliability of health information available on social media to patients regarding laryngological conditions.

RESUMO

BACKGROUND: In the past decade, there has been a rise in social media applications and usage among individuals in the otolaryngology- head and neck surgery (OHNS) community. Hashtags (#), used to identify posts relating to similar topics, are utilized to search medical information, build a network, find providers, and discuss research. Previous OHNS literature in this arena includes a standard ontology, or list of hashtags, developed for the otology subspecialty. To date, the ontology of laryngology hashtags has not been created. The objective of this study is to propose a standardized ontology to use when discussing topics in laryngology on social media to maximize reach and effect. METHODS: Using a combination of previously published techniques, along with laryngology specific adjustments, the authors developed a list of suggested hashtags. An initial list was systematically culled from laryngology Instagram accounts including academic programs, laryngology influencers (fellowship-trained laryngologists with publicly available professional accounts with greater than 500 followers), and professional societies/conferences. The list was abbreviated using current rate of use, specificity, and expert opinion. These were then categorized to include general terms, diseases and diagnoses, and treatment strategies RESULTS: Across all culled Instagram posts, there were 240 unique laryngology hashtags used and 1152 total hashtags were applied. The authors derived unique terms to be included in the ontology for laryngology by expert opinion of fellowship-trained laryngologists. CONCLUSION: Laryngology is in the early stages of utilization of social media. Developing a specific ontology of hashtags to be used will optimize the reach and connections of term specific searches.

RESUMO

INTRODUCTION: Chronic cough is a persistent cough lasting greater than eight weeks. The prevalence rate is estimated to be 9% to 33% in the United States. There are several treatment modalities described in current literature including medical, surgical, and behavioral interventions. Behavioral intervention with a speech-language pathologist (SLP) includes education on laryngeal hygiene and the voluntary control of cough as well as respiratory retraining to suppress or reduce the duration of cough. Cough suppression therapy, like other behavioral therapies, requires patient motivation and commitment to participation and completion in therapy. METHODS: This study was a prospective cross-sectional survey at a single academic institution. Adult patients evaluated by a laryngologist for chronic cough regardless of their primary etiology were included. Patients who were tracheostomy dependent, on oxygen therapy, had vocal fold paralysis/immobility, or had undergone previous laryngeal surgery were excluded. Patients were surveyed at the end of the initial clinic visit or at the beginning of the first cough suppression therapy session. Subjects reported their motivational factors for undergoing cough suppression therapy. RESULTS: The majority of patients, 21 (58.33%), identified as female, 15 patients (41.20%) identified as male, and no patients identified as transgender, nonbinary, and/or other gender. The patients in this study had a mean age of 57.75 (12.12) years. 35 patients (97.22%) were interested in cough suppression therapy. The mean presenting cough severity index (CSI) was 19.39 (10.28) with the mean cough duration of 8.69 (12.10) years. CONCLUSIONS: Patients primarily sought cough suppression therapy due to intrinsic factors rather than extrinsic influence. By understanding the relationship between symptomatology and patient motivation, clinicians can better counsel their patients and improve methods to assess candidacy for behavioral treatment.

RESUMO

OBJECTIVES: Improved screening has decreased but not eliminated the need for emergent surgery for colon cancer (CC), many of which are performed by acute care surgery (ACS) surgeons. This retrospective review compares outcomes for CC resections on the ACS service to the surgical oncology and colorectal services (SO/CRS). METHODS: Retrospective review was performed for CC operations between 2014 and 2019. Data for margin status, cancer stage, number of lymph nodes dissected, time to medical oncology follow-up, and time to initiation of chemotherapy were collected. Patients with curative resection, who chose comfort care, presented on alternative services or with non-CC indications as well as those were lost to follow-up were excluded. RESULTS: 36 ACS patients and 269 SO/CRS patients underwent CC resections. Most ACS patients presented emergently compared to the SO/CC group (83.3% vs 1%, P < .05) as well as with more advanced tumor stage. There were no statistically significant differences for presence of metastatic disease, number of lymph nodes obtained, or time to post-surgical care (in days) and chemotherapy initiation (in days). 3 (8%) EGS patients had positive margins compared to 6 (2%) CRS/SO patients due to the presence of perforated tumors in the ACS group (p < .05). There were no statistically significant differences in 30- day or 1-year mortality despite the emergent presentation of the ACS patients. DISCUSSION: These findings suggest that despite emergent presentation and advanced disease burden, ACS surgeons provide quality care to CC patients, both in the operating room and in coordination of care.

RESUMO

OBJECTIVES: Patient-reported outcome measures (PROMs) are used to evaluate patients' symptoms and clinical improvement after an intervention. Advocacy efforts and increased provider awareness regarding health literacy have helped to improve the readability of PROMs. Recent studies in otolaryngology in rhinology, pediatric otolaryngology, and head and neck reported PROM readability scores above the sixth-grade level. However, there is limited data regarding the readability of laryngology PROMs. Thus, this study aims to report the readability levels of PROMs in laryngology by assessing different readability indices and describing the relationship of readability levels to equitable healthcare. METHODS: This is a bibliometric study that received approval from institutional review board (IRB) review as a nonhuman subject research study. Recent and widely utilized laryngology PROMs were selected from a publicly available literature search by reviewing laryngology systematic reviews, PubMed, and Google Scholar. Laryngology PROMs were selected from voice, dysphagia, airway, and other PROMs including voice questionnaires administered to patients seeking gender affirming voice care from systematic reviews and expert opinion. There were 37 PROMs included in this study. PROMs were analyzed via Gunning Fog, Simple Measure of Gobbledygook (SMOG), FORCAST, and Flesch Reading Ease Score. RESULTS: All laryngology PROMs had readabilities above the recommended sixth-grade level. The mean and standard deviation (SD) of Gunning Fog was 7.30 (2.59), SMOG was 8.70 (1.51), FORCAST was 10.05 (1.51), and Flesch Reading Ease Score was 8.08 (2.76). CONCLUSION: Laryngology PROMs are above the recommended middle school reading level. To further promote health equity, readability should be considered when developing future PROMs. LEVEL OF EVIDENCE: NA Laryngoscope, 132:1069-1074, 2022.

RESUMO

BACKGROUND: Laryngologists use patient-reported outcome measures (PROM) to determine the efficacy of an intervention or to evaluate a patient's symptomatology. PROMs should be developed for a diverse target audience, including patients of all literacy levels. The American Medical Association (AMA) recommends that PROMs are written at or below the sixth- grade level. In recent studies, readability scores for otolaryngology PROMs in English were above the recommended reading level. To date, there is limited data regarding the readability of Spanish PROMs. Thus, this study aims to report the readability of Spanish language PROMs in laryngology. METHODS: This study analyzed nine Spanish language laryngology PROMs. The authors queried PROMs from PubMed and Google scholar based upon English language laryngology PROM systematic reviews. Common categories included voice, airway, dysphagia, and other laryngology PROMs. Only nine laryngology PROMs were translated and validated in the Spanish language and publicly available. The readability of Spanish PROMs was determined using a multi-lingual readability software by two readability indices: Fernández Huerta and INFLESZ. RESULTS: The mean and standard deviation (SD) Fernández-Huerta was 75.25 (27.12) and INFLESZ was 71.25 (26.98). The average readability score per PROM in Spanish was: DI (84.19), EAT-10 (11.54), MDADI (64.92), RSI (57.22), SWAL-QoL (70.98), TVQ (87.64), VFI (99.46), VHI-10 (95.04), and VRQoL (88.28). CONCLUSION: The mean readability of Spanish language laryngology PROMs was above the recommended reading level. Patient readability should be considered when developing laryngology PROMs translations and validations. Robust development and testing of novel PROMs are important to address the persistent, pervasive risks for Spanish speaking patients.

RESUMO

BACKGROUND: Pediatric otolaryngology encompasses interactions with a young patient, parent and/or guardian, and the provider. As healthcare transitions toward patient-centered care, clinicians are using direct tools of measurement such as patient-reported outcome measures (PROM) as a modality of communication between the patient and healthcare provider. Therefore, literacy levels of both the patient and their parent or guardian must be considered. Moreover, PROMs administered in pediatric audiology and otolaryngology in Spanish were found to be above the recommended reading level. Assessing the readability of Spanish translated PROMs is vital in providing safe, accurate, and quality care. The goal of this study is to analyze the readability of PROMs in pediatric otolaryngology and assess their compliance with readability recommendations. METHODS: Pediatric otolaryngology PROMs were identified from Powell's systematic review on pediatric otolaryngology PROMs. Spanish pediatric otolaryngology PROMs were selected from a literature search through PubMed (pubmed.ncbi.nlm.nih.gov) and Google scholar databases (scholar.google.com). After completion of the literature search, seven PROMs were identified. Only four PROMs Spanish validations included the translation of the PROM in their publication. The authors of the remaining PROMs were contacted via email. Ultimately, eight pediatric otolaryngology PROMs were included in this study. The PROMs included were assessed by a Latin Spanish translator for grammar, syntax, and comprehension ease. RESULTS: Four out of eight PROMs (50%) included in our study had readabilities above the recommended sixth-grade level. The following PROMs were noted with readabilities above the recommended level: tonsil & adenoid health status instrument (TAHSI), the nasal quality of life survey (SN-5), Spanish pediatric voice handicap index (P-VHI), and velopharyngeal insufficiency effects on life outcome (VELO). CONCLUSIONS: Currently, some Spanish translated pediatric PROMs are written at a reading level above the recommended range for patients and their families.

RESUMO

Acute epiglottitis is an airway emergency presenting with edema and inflammation of the epiglottis and aryepiglottic folds [1]. Infectious and other non-infectious etiologies may cause significant airway injury presenting with similar clinical symptoms and radiographic findings [1]. While many causes of thermal epiglottitis have been described in the pediatric and young adult population, we describe an unusual case of an adolescent patient with cannabis induced thermal epiglottitis. A 17-year-old previously healthy, vaccinated adolescent male presented to the pediatric emergency department with dysphagia, odynophagia, drooling, and muffled voice with fever, tachypnea, and leukocytosis. Lateral plain film imaging and computed tomography (CT) scan showed significant edema of the epiglottitis. Urinary drug screen in the emergency department was positive for benzodiazepine, opiates, and cannabinoids. Transnasal flexible laryngoscopy and direct laryngoscopy demonstrated significant erythema, edema, and copious secretions. Culture of the epiglottis culture showed normal oropharyngeal flora. The patient was diagnosed with thermal induced epiglottitis secondary to cannabinoid use based on positive substance use history, urinary drug screen, and negative bacterial cultures. Clinicians must consider thermal injury of the epiglottitis due to substance use, specifically marijuana in vaccinated adolescent patients presenting with positive substance use history, progressive dysphagia, odynophagia, and drooling with a muffled voice. It is essential to obtain a thorough history and physical examination and urinary drug screen in the pediatric emergency department since the clinical and radiographic findings are similar in epiglottitis due to infectious and non-infectious etiologies. Prompt management with intubation should occur to protect and maintain airway integrity.
