Therapeutic benefit of idebenone in patients with Leber hereditary optic neuropathy: The LEROS nonrandomized controlled trial.

Leber hereditary optic neuropathy (LHON) is a mitochondrial disease leading to rapid and severe bilateral vision loss. Idebenone has been shown to be effective in stabilizing and restoring vision in patients treated within 1 year of onset of vision loss. The open-label, international, multicenter, natural history-controlled LEROS study (ClinicalTrials.gov NCT02774005) assesses the efficacy and safety of idebenone treatment (900 mg/day) in patients with LHON up to 5 years after symptom onset (N = 199) and over a treatment period of 24 months, compared to an external natural history control cohort (N = 372), matched by time since symptom onset. LEROS meets its primary endpoint and confirms the long-term efficacy of idebenone in the subacute/dynamic and chronic phases; the treatment effect varies depending on disease phase and the causative mtDNA mutation. The findings of the LEROS study will help guide the clinical management of patients with LHON.

Quantifying surgical completeness in patients with aspirin exacerbated respiratory disease.

BACKGROUND: Aspirin exacerbated respiratory disease (AERD) in patients who have had sinus surgery remains a management challenge. Aspirin desensitization and biologics are additional treatment options. It remains unclear if patients require a more comprehensive surgery prior to implementing such additional therapies. The purpose of this study was to quantify prior surgery completeness in AERD patients at a tertiary rhinology practice. METHODS: Paranasal sinus CT scans were reviewed by four academic rhinologists to assess surgery completeness. Using a published CT grading system, each sinus was graded on the completeness of surgery and middle turbinate reduction. A score out of 14 was calculated for each patient (7 per side). RESULTS: Sixty-one patients with AERD out of 141 available were included. Mean inter-rater agreement across all sinuses was moderate (k = 0.42). The mean completeness score was 6.7/14. The following procedures were rated as complete (means): uncinectomy (L: 84%, R: 82%, k = 0.44), maxillary (L: 83%, R: 77%, k = 0.32), middle turbinate reduction (L: 45%, R: 46%, k = 0.31), anterior ethmoid (L: 35%, R: 39%, k = 0.51), sphenoid (L: 36%, R: 35%, k = 0.4), posterior ethmoid (L: 30%, R: 30%, k = 0.48), frontal (L: 22%, R: 21%, k = 0.46). CONCLUSION: Prior surgery in AERD patients were mostly deemed incomplete. Uncinectomy and maxillary antrostomy are the most common procedures previously performed. It remains toe seen whether this would be considered 'adequate' surgery or more 'complete' surgery is required to achieve greater disease control.

Anterior segment ischemia following strabismus surgery in a young adult using gender-affirming estrogen hormone therapy.

Well-known risk factors for anterior segment ischemia (ASI) following strabismus surgery include ipsilateral surgery on three or more rectus muscles, older age, and vasculopathy. ASI is rarely reported in young patients following uneventful strabismus surgery on two ipsilateral rectus muscles. We report a 30-year-old transgender female on long-term estrogen therapy who underwent strabismus surgery involving recessions of both lateral rectus muscles, the right inferior rectus muscle, and the left superior rectus muscle. The left eye developed severe ASI with hypotony maculopathy that was resistant to topical medications, oral steroids, anterior chamber reformation, and intravitreal steroid injection. Following phacoemulsification with intraocular lens and capsular tension ring insertion 1 year later, intraocular pressure and hypotony maculopathy improved.

The educational value of thyroidectomy YouTube videos for surgical trainees.

OBJECTIVE: To evaluate the usefulness of thyroidectomy videos posted on YouTube for surgical training. METHODS: The following keywords were searched on YouTube: "thyroidectomy", "conventional thyroidectomy", "hemithyroidectomy", and "thyroid lobectomy". The first 30 videos from each search were selected for a total of 120 videos. Included videos were those displaying a conventional approach to thyroidectomy and real, non-animated patient surgery. Two independent reviewers assessed each video using the LAParoscopic surgery Video Educational Guidelines (LAP-VEGaS) and a thyroidectomy-specific grading score (TSS). RESULTS: The search yielded 22 videos that met the selection criteria. The inter-rater agreement was excellent for the grading systems (ICC = 0.910). The average LAP-VEGaS score was of medium quality (8.82 ± 3.56 standard deviation (SD)). The highest average score (11.00 ± 1.68 SD) was assigned to videos published from academic institutions. There was no statistically significant difference in LAP-VEGaS scores when comparing the type of publisher between videos (p = 0.132). The majority of the videos (12/22, 55 %) did not include all hallmarks of thyroidectomy according to the novel TSS score. There was a significant positive correlation between TSS markers and the overall LAP-VEGaS score (r = 0.577, p = 0.005). CONCLUSION: YouTube videos as an educational resource for thyroidectomy instructions vary in quality. Most of the thyroidectomy videos were medium quality according to the LAP-VEGaS score. YouTube sourced thyroidectomy videos should be used to supplement traditional educational methods.

A critical readability and quality analysis of internet-based patient information on neck dissections.

Objective: Patients are increasingly turning to the Internet as a source of healthcare information. Given that neck dissection is a common procedure within the field of Otolaryngology - Head and Neck Surgery, the aim of this study was to evaluate the quality and readability of online patient education materials on neck dissection. Methods: A Google search was performed using the term "neck dissection." The first 10 pages of a Google search using the term "neck dissection" were analyzed. The DISCERN instrument was used to assess quality of information. Readability was calculated using the Flesch-Reading Ease, Flesch-Kincaid Grade Level, Gunning-Fog Index, Coleman-Liau Index, and Simple Measure of Gobbledygook Index. Results: Thirty-one online patient education materials were included. Fifty-five percent (n = 17) of results originated from academic institutions or hospitals. The mean Flesch-Reading Ease score was 61.2 ± 11.9. Fifty-two percent (n = 16) of patient education materials had Flesch-Reading Ease scores above the recommended score of 65. The average reading grade level was 10.5 ± 2.1. The average total DISCERN score was 43.6 ± 10.1. Only 26% of patient education materials (PEMs) had DISCERN scores corresponding to a "good quality" rating. There was a significant positive correlation between DISCERN scores and both Flesch-Reading Ease scores and average reading grade level. Conclusions: The majority of patient education materials were written above the recommended sixth-grade reading level and the quality of online information pertaining to neck dissections was found to be suboptimal. This research highlights the need for patient education materials regarding neck dissection that are high quality and easily understandable by patients.

Cannabis use amongst tinnitus patients: consumption patterns and attitudes.

BACKGROUND: Tinnitus has a significant impact on quality of life and causes considerable psychological distress. Cannabis is known to modulate neuron hyperexcitability, provide protection against auditory damage, and has been used for treatment for many diseases which have physiological similarities with tinnitus. The objective of this study was to survey patients presenting with tinnitus regarding their perspectives and usage patterns of cannabis. METHODS: Patients with a primary presenting complaint of tinnitus in a tertiary neuro-otology clinic completed a 18-item questionnaire assessing perception, attitudes, and cannabis usage patterns. RESULTS: Forty five patients completed the survey (mean age: 54.5 years, 31 females and 14 males). Overall, 96% of patients reported that they would consider cannabis as treatment for their tinnitus. Patients considered cannabis use for auditory symptoms (91%), and symptoms related to their tinnitus, such as emotional complaints (60%), sleep disturbances (64%), and functional disturbances (56%). 36% of patients had previously used cannabis and 22% of patients reported cannabis use at the time of the study. 80% of patients that were actively using cannabis reported that it helped with tinnitus-related symptoms, such as dizziness, anxiety, bodily pain, and sleep disturbances. Most patients would prefer to use edibles (62%), tablet (58%) and cream (47%) formulations of cannabis. Patients were concerned about the cost (29%), potential physical health implications (53%) and psychosocial side effects (60%) of cannabis. Over half of patients learned about cannabis from a friend or family member and only 22% of patients learned about cannabis from a physician or nurse. CONCLUSION: Cannabis use is common amongst patients with tinnitus and current users of cannabis reported that it helped with their symptoms. Most patients would consider its use as a potential treatment to alleviate their tinnitus-related symptoms and are interested in learning more regarding its use. By understanding how cannabis is perceived by tinnitus patients, healthcare providers can provide appropriate patient education.

Attitudes Toward and Acceptability of Medical Marijuana Use Among Head and Neck Cancer Patients.

OBJECTIVE: This study aims to understand the attitudes toward marijuana in HNC patients. METHODS: A 17-question questionnaire regarding medical marijuana (MM) was distributed to HNC patients at a tertiary cancer center. RESULTS: 63 HNC patients completed the questionnaire. Patients that had used or were using marijuana described benefit with symptoms of headache, pain, nausea, and loss of appetite. 83% of all patients considered marijuana as treatment for cancer related pain and 67% as treatment for cancer related anxiety. About 70% of patients actively undergoing cancer treatment believed marijuana medications would help with symptoms during treatment. CONCLUSIONS: By understanding how HNC patients perceive MM, HNC teams may be able to prescribe and educate their patients on MM.

Clinicopathological Predictors of Survival for Parotid Mucoepidermoid Carcinoma: A Systematic Review.

OBJECTIVE: Various prognostic factors are associated with the survival of patients with parotid mucoepidermoid carcinoma (MEC). The aim of this systematic review is to summarize the clinical and pathologic prognostic factors on survival outcomes in patients with parotid MEC. DATA SOURCES: Articles published from database inception to July 2020 on OVID Medline, OVID Embase, Cochrane Central, and Scopus. REVIEW METHODS: Studies were included that reported clinical or pathologic prognostic factors on survival outcomes for adult patients with parotid MEC. Data extraction, risk of bias, and quality assessment were conducted by 2 independent reviewers. RESULTS: A total of 4290 titles were reviewed, 396 retrieved for full-text screening, and 18 included in the review. The average risk of bias was high, and quality assessment for the prognostic factors ranged from very low to moderate. Prognostic factors that were consistently associated with negative survival outcomes on multivariate analysis included histologic grade (hazard ratio [HR], 5.66), nodal status (HR, 2.86), distant metastasis (HR, 3.10-5.80), intraparotid metastasis (HR, 13.52), and age (HR, 1.02-6.86). Prognostic factors that inconsistently reported associations with survival outcomes were TNM stage, T classification, and N classification. CONCLUSION: Histologic grade, nodal status, distant metastasis, intraparotid metastasis, and age were associated with worse survival outcomes. These prognostic factors should be considered when determining the most appropriate treatment and follow-up plan for patients with parotid MEC.

Video-based coaching for surgical residents: a systematic review and meta-analysis.

BACKGROUND: Video-based coaching (VBC) is used to supplement current teaching methods in surgical education and may be useful in competency-based frameworks. Whether VBC can effectively improve surgical skill in surgical residents has yet to be fully elucidated. The objective of this study is to compare surgical residents receiving and not receiving VBC in terms of technical surgical skill. METHODS: The following databases were searched from database inception to October 2021: Medline, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and PubMed. Articles were included if they were randomized controlled trials (RCTs) comparing surgical residents receiving and not receiving VBC. The primary outcome, as defined prior to data collection, was change in objective measures of technical surgical skill following implementation of either VBC or control. A pairwise meta-analyses using inverse variance random effects was performed. Standardized mean differences (SMD) were used as the primary outcome measure to account for differences in objective surgical skill evaluation tools. RESULTS: From 2734 citations, 11 RCTs with 157 residents receiving VBC and 141 residents receiving standard surgical teaching without VBC were included. There was no significant difference in post-coaching scores on objective surgical skill evaluation tools between groups (SMD 0.53, 95% CI 0.00 to 1.01, p = 0.05, I2 = 74%). The improvement in scores pre- and post-intervention was significantly greater in residents receiving VBC compared to those not receiving VBC (SMD 1.62, 95% CI 0.62 to 2.63, p = 0.002, I2 = 85%). These results were unchanged with leave-one-out sensitivity analysis and subgroup analysis according to operative setting. CONCLUSION: VBC can improve objective surgical skills in surgical residents of various levels. The benefit may be most substantial for trainees with lower baseline levels of objective skill. Further studies are required to determine the impact of VBC on competency-based frameworks.

Acute idiopathic blind spot enlargement syndrome (AIBSES) with retinal vasculitis.

Purpose: To report the clinical and anatomical features of an unusual case of acute idiopathic blind spot enlargement syndrome (AIBSES) with retinal vasculitis. Observations: A 39-year-old patient, who was a known case of chronic headache with nonspecific visual symptoms for nine years, developed scotomas in her right eye. She was initially diagnosed with AIBSES which had been stable, but later worsened with symptoms of subsequent blind spot enlargement and photopsia on the left eye a year later. Increase in the size of the blind spot over the left eye and stability of the blind spot enlargement over the right eye was documented on Humphrey visual field (HVF) testing. Due to the rapid onset and severity of symptoms, an inflammatory etiology was entertained and this prompted referral to our clinic. At initial presentation, fluorescein angiogram (FA) revealed moderate diffuse vasculitis and disc leakage in the left eye, which existed alongside the enlarged blind spot. Corticosteroid treatment was suggested and initiated. The patient was found to have a reduction in the size of her blind spot and a decrease in severity of retinal vasculitis a month later. Unfortunately, the patient was then lost to follow up and had stopped steroid treatment of her own accord. After nine months without treatment, the patient's blind spot increased to a larger size than her initial presentation, as documented on HVF, with recurrence of vasculitis in the left eye. Conclusion and Importance: This is an unusual case of AIBSES which presented with vasculitis and rapid progression and has responded to steroids. Though monocular AIBSES has been shown to later affect the contralateral eye, concurrent vasculitis with AIBSES has not previously been reported. Furthermore, the response to treatment with reduction in blind spot enlargement is unusual for AIBSES. These findings stress the need for regular monitoring in cases of AIBSES.

Post-operative survival in head and neck cancer patients with elevated troponins.

OBJECTIVES: The strenuous demands of head and neck cancer surgery (HNS) place patients at increased risk of myocardial injury. Troponin positivity (TP) post-operatively is a predictor of increased complications and mortality. The present study is the first to investigate the effects of TP on potential delays in adjuvant treatment and disease-specific survival. DESIGN, SETTING, PARTICIPANTS AND MAIN OUTCOME MEASURES: All patients undergoing HNS from 2014 to 2016 had troponins measured at a single academic centre. Relevant patient data was extracted on retrospective chart review. The main outcome measures were the impact of TP on timing of adjuvant treatment and disease-specific survival. RESULTS: Of 166 patients, 26 (15.6%) developed TP post-operatively. There was no significant difference between cohorts for baseline characteristics except for age. Overall and disease-specific survival for TP patients were respectively 45.9% and 57.4% at 3 years. There was no significant difference between cohorts for overall and disease-specific survival, and time to adjuvant therapy. CONCLUSION: No significant association was found between TP and overall and disease-specific survival, and time to adjuvant therapy.

Septin-5 and -7-IgGs: Neurologic, Serologic, and Pathophysiologic Characteristics.

BACKGROUND AND OBJECTIVES: We sought to determine clinical significance of neuronal septin autoimmunity and evaluate for potential IgG effects. METHODS: Septin-IgGs were detected by indirect immunofluorescence assays (IFAs; mouse tissue and cell based) or Western blot. IgG binding to (and internalization of) extracellular septin epitopes were evaluated for by live rat hippocampal neuron assay. The impact of purified patient IgGs on murine cortical neuron function was determined by recording extracellular field potentials in a multielectrode array platform. RESULTS: Septin-IgGs were identified in 23 patients. All 8 patients with septin-5-IgG detected had cerebellar ataxia, and 7 had prominent eye movement disorders. One of 2 patients with co-existing septin-7-IgG had additional psychiatric phenotype (apathy, emotional blunting, and poor insight). Fifteen patients had septin-7 autoimmunity, without septin-5-IgG detected. Disorders included encephalopathy (11; 2 patients with accompanying myelopathy, and 2 were relapsing), myelopathy (3), and episodic ataxia (1). Psychiatric symptoms (≥1 of agitation, apathy, catatonia, disorganized thinking, and paranoia) were prominent in 6 of 11 patients with encephalopathic symptoms. Eight of 10 patients with data available (from 23 total) improved after immunotherapy, and a further 2 patients improved spontaneously. Staining of plasma membranes of live hippocampal neurons produced by patient IgGs (subclasses 1 and 2) colocalized with pre- and post-synaptic markers. Decreased spiking and bursting behavior in mixed cultures of murine glutamatergic and GABAergic cortical neurons produced by patient IgGs were attributable to neither antigenic crosslinking and internalization nor complement activation. INTERPRETATION: Septin-IgGs are predictive of distinct treatment-responsive autoimmune central nervous system (CNS) disorders. Live neuron binding and induced electrophysiologic effects by patient IgGs may support septin-specific pathophysiology. ANN NEUROL 2022;92:1090-1101.

Validity and Usefulness of YouTube Videos Related to Endoscopic Transsphenoidal Surgery for Patient Information.

Objectives This article evaluates the completeness and accuracy of YouTube videos related to endoscopic transsphenoidal surgery (ETS) as a source for patient information. Design YouTube was searched using relevant terms pertaining to ETS. Videos were evaluated independently by two physician reviewers experienced in ETS. Video demographics including uploader source along with validity scores based on predetermined checklists were captured. Setting Internet. Participants Not applicable. Main Outcome Measures A novel ETS scoring checklist, the modified DISCERN criteria, and Journal of the American Medical Association (JAMA) benchmark score were used to measure completeness and accuracy of videos. video power index (VPI) was calculated to reflect popularity. Intraclass correlation coefficient was calculated for rater agreement. Results Seventy-nine videos were included in final scoring and analysis. The ETS score, DISCERN, JAMA, and mean VPI across all included videos were 5.0 ± 2.7, 2.4 ± 0.83, 2.19 ± 0.62, and 8.92 ± 18.1, respectively. Based on the ETS score checklist, 31 (39%) of the videos were rated as poor, 30 (38%) were moderately useful, 17 (22%) were useful, and 1 (1%) was exceptional. There was a significant positive correlation between the ETS, DISCERN, and JAMA scores ( p < 0.001), but no correlation with VPI and the validity scores. There were no significant differences comparing validity scores based on the uploader source. Conclusion YouTube videos related to ETS have limited usefulness and poor overall validity for patient information. Clinicians should direct patients to other validated sources of information and aim to improve the comprehensiveness of ETS-related videos.

Modalities of Post-Rhinoplasty Edema and Ecchymosis Measurement: A Systematic Review.

Background: Post-rhinoplasty edema and ecchymosis can influence patient satisfaction with surgery as well as result in poor quality of life. Methods to quantify such edema and ecchymosis have been described in the literature. Despite this, there is currently no collective understanding of which methods are the most effective. Hence, this systematic review aims to describe and analyze the literature on post-rhinoplasty edema and ecchymosis measurement techniques. Methods: Standard bibliographic databases (OVID Medline, EMBASE, and PubMed) were searched from their inception to December 2019 for the terms: "rhinoplasty", "postoperative", "edema", and "ecchymosis". Descriptive analysis was completed. Results: The search revealed 1116 articles of which 33 met inclusion criteria and were included for qualitative synthesis. A total of 1801 patients from all studies were included. Of the 33 included studies, there were 57 unique ecchymosis/edema measurements. The majority of studies measured edema/ecchymosis on post-operative day 1, 2, 3 and 7. Ninety-three percent of measurements described were taken subjectively from a human rater. Other techniques described included magnetic resonance imaging, ultrasound, 3-dimensional imaging, and digital analysis. Less than half of the subjective ecchymosis/edema gradings were completed by a blinded rater. Conclusion: There are a wide variety of post-rhinoplasty edema and ecchymosis techniques being used by rhinoplasty surgeons. The majority of post-rhinoplasty edema and ecchymosis measurements are completed by unblinded subjective raters. It is important that facial plastic surgeons select an accurate measurement tool so they may be able to initiate precise patient-specific management of edema and ecchymosis.

Historique: L'œdème et les ecchymoses après une rhinoplastie peuvent nuire à la satisfaction du patient envers l'opération et entraîner une mauvaise qualité de vie. Les publications contiennent des méthodes pour les quantifier. Pourtant, il n'y a actuellement aucune compréhension collective de la méthode la plus efficace. La présente analyse systématique vise à décrire et à analyser les publications sur les techniques de mesure de l'œdème et des ecchymoses après une rhinoplastie. Méthodologie: Les chercheurs ont fouillé les bases de données bibliographiques standards (OVID Medline, EMBASE et PubMed) à compter de leur création jusqu'à décembre 2019 au moyen des termes rhinoplasty, postoperative, edema et ecchymosis. Ils ont procédé à l'analyse descriptive. Résultats: La recherche a permis d'extraire 1 116 articles, dont 33 respectaient les critères d'inclusion et ont servi à la synthèse qualitative. Au total, 1 801 patients de toutes les études ont été retenus. Les 33 articles étudiés contenaient 57 mesures différentes des ecchymoses et de l'œdème. Dans la majorité des études, la mesure de l'œdème et des ecchymoses avait lieu le premier, le deuxième, le troisième et le septième jour après l'opération. Par ailleurs, 93% des mesures décrites avaient été prises de manière subjective par un évaluateur humain. Parmi les autres techniques décrites, soulignons l'imagerie par résonance magnétique, l'échographie, l'imagerie tridimensionnelle et l'analyse numérique. Moins de la moitié des évaluations subjectives des ecchymoses et de l'œdème avait été effectuée par un évaluateur en insu. Conclusion: Les chirurgiens spécialisés en rhinoplastie recourent à une vaste gamme de techniques pour mesurer l'œdème et les ecchymoses après une rhinoplastie. La majeure partie de ces mesures est effectuée par des évaluateurs subjectifs sans insu. Il est important que les chirurgiens faciaux choisissent un outil de mesure précis pour pouvoir entreprendre une prise en charge de l'œdème et des ecchymoses adaptée au patient.

Nasal Septal Perforation Reconstruction with Polydioxanone Plate: A Systematic Review.

Nasal septal perforation is an uncommon pathology that is difficult to surgically repair and may significantly impact patients' quality of life. Existing treatments have high complication and failure rates. The use of polydioxanone (PDS) plates to repair septal perforations is an innovative approach that has demonstrated superior outcomes to the conventional techniques. This study aimed to review the literature on PDS plates for nasal septal perforation reconstruction. PubMed, OVID Medline, and OVID Embase databases were searched for relevant articles in June 2021. Search terms included nasal septal perforation, polydioxanone, septal perforation, septal repair, nasal septum, and PDS plate. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were adhered to for this systematic review. Database searches yielded 80 articles. Seven articles were included representing 74 patients. All studies reported the use of PDS plates in addition to other materials. They all reported closure rates of at least 80%. The majority of studies reported no postoperative complications. Nasal septal perforation reconstruction with PDS plates is a promising approach that has demonstrated positive outcomes. Further larger studies are required to evaluate the long-term efficacy of using PDS plates on patients with septal perforations.

Critical Quality and Readability Analysis of Online Patient Education Materials on Parotidectomy: A Cross-Sectional Study.

PURPOSE: Complications related to parotidectomy can cause significant morbidity, and thus, the decision to pursue this surgery needs to be well-informed. Given that information available online plays a critical role in patient education, this study aimed to evaluate the readability and quality of online patient education materials (PEMs) regarding parotidectomy. METHODS: A Google search was performed using the term "parotidectomy" and the first 10 pages of the search were analyzed. Quality and reliability of the online information was assessed using the DISCERN instrument. Flesch-Kincaid Grade Level (FKGL) and Flesch-Reading Ease Score (FRE) were used to evaluate readability. RESULTS: Thirty-five PEMs met the inclusion criteria. The average FRE score was 59.3 and 16 (46%) of the online PEMs had FRE scores below 60 indicating that they were fairly difficult to very difficult to read. The average grade level of the PEMs was above the eighth grade when evaluated with the FKGL. The average DISCERN score was 41.7, which is indicative of fair quality. There were no significant differences between PEMs originating from medical institutions and PEMs originating from other sources in terms of quality or readability. CONCLUSION: Online PEMs on parotidectomy may not be comprehensible to the average individual. This study highlights the need for the development of more appropriate PEMs to inform patients about parotidectomy.

Operating Room Noise and Team Communication during Facial Plastic and Reconstructive Surgery: A Multicenter Study.

Operating room (OR) noise contributes to team miscommunication. In facial plastic and reconstructive surgery (FPRS), many cases are completed under sedation. This creates a unique environment wherein patients are aware of OR noise. The objectives of this study were to quantify noise and evaluate team members' perspectives on communication inside of FPRS ORs. This study was completed across three surgical institutions. Objective noise measurements were recorded with SoundMeter X. A communication questionnaire was delivered to OR team members following each case. Four hundred and twenty-three noise measurements were recorded during facelift/neck, eye/brow, rhinoplasty, and fat transfer/lip surgeries. The mean and maximum noise levels were 66.1 dB (dB) and 87.6 dB, respectively. Measurements during cases with general anesthetic (221/423, 52.2%) had higher noise measurements (70.3 dB) compared with those with sedation (202/423, 47.8%) (69.7 dB) (p = 0.04). The OR was louder with suction on (72.3 dB) versus off (69.3 dB) (p <0.00). Suction (34.5%) and music (22.4%) were the largest noise contributors according to questionnaire replies. Intraoperative noise, awake patients, and suctions/music may negatively impact FPRS OR communication. Innovation to improve FPRS intraoperative communication should be considered for effective patient care.

Fecal microbiome and bile acid metabolome in adult short bowel syndrome.

Loss of functional small bowel surface area causes short bowel syndrome (SBS), intestinal failure, and parenteral nutrition (PN) dependence. The gut adaptive response following resection may be difficult to predict, and it may take up to 2 yr to determine which patients will wean from PN. Here, we examined features of gut microbiota and bile acid (BA) metabolism in determining adaptation and ability to wean from PN. Stool and sera were collected from healthy controls and from patients with SBS (n = 52) with ileostomy, jejunostomy, ileocolonic, and jejunocolonic anastomoses fed with PN plus enteral nutrition or who were exclusively enterally fed. We undertook 16S rRNA gene sequencing, BA profiling, and 7α-hydroxy-4-cholesten-3-one (C4) quantitation with LC-MS/MS and serum amino acid analyses. Patients with SBS exhibited altered gut microbiota with reduced gut microbial diversity compared with healthy controls. We observed differences in the microbiomes of patients with SBS with ileostomy versus jejunostomy, jejunocolonic versus ileocolonic anastomoses, and PN dependence compared with those who weaned from PN. Stool and serum BA composition and C4 concentrations were also altered in patients with SBS, reflecting adaptive changes in enterohepatic BA cycling. Stools from patients who were weaned from PN were enriched in secondary BAs including deoxycholic acid and lithocholic aicd. Shifts in gut microbiota and BA metabolites may generate a favorable luminal environment in select patients with SBS, promoting the ability to wean from PN. Proadaptive microbial species and select BA may provide novel targets for patient-specific therapies for SBS.NEW & NOTEWORTHY Loss of intestinal surface area causes short bowel syndrome, intestinal failure, and parenteral nutrition dependence. We analyzed the gut microbiota and bile acid metabolome of a large cohort of short bowel syndrome adult patients with different postsurgical anatomies. We report a novel analysis of the microbiome of patients with ileostomy and jejunostomy. Enrichment of specific microbial and bile acid species may be associated with the ability to wean from parenteral nutrition.
