Objective: Initiating postoperative radiotherapy (PORT) within 6 weeks of surgery for head and neck squamous cell carcinoma (HNSCC) is included in the National Comprehensive Cancer Network Clincal Practice Guidelines and is a Commission on Cancer quality metric. Factors associated with delays in starting PORT have not been systematically described nor synthesized., Data Sources: PubMed, Scopus, and CINAHL., Review Methods: We included studies describing demographic characteristics, clinical factors, or social determinants of health associated with PORT delay (>6 weeks) in patients with HNSCC treated in the United States after 2003. Meta-analysis of odds ratios (ORs) was performed on nonoverlapping datasets., Results: Of 716 unique abstracts reviewed, 21 studies were included in the systematic review and 15 in the meta-analysis. Study sample size ranged from 19 to 60,776 patients. In the meta-analysis, factors associated with PORT delay included black race (OR, 1.46, 95% confidence interval [CI]: 1.28-1.67), Hispanic ethnicity (OR, 1.37, 95% CI, 1.17-1.60), Medicaid or no health insurance (OR, 2.01, 95% CI, 1.90-2.13), lower income (OR, 1.38, 95% CI, 1.20-1.59), postoperative admission >7 days (OR, 2.92, 95% CI, 2.31-3.67), and 30-day hospital readmission (OR, 1.37, 95% CI, 1.29-1.47)., Conclusion: Patients at greatest risk for a delay in initiating guideline-adherent PORT include those who are from minoritized communities, of lower socioeconomic status, and experience postoperative challenges. These findings provide the foundational evidence needed to deliver targeted interventions to enhance equity and quality in HNSCC care delivery., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Objective: To determine if librarian collaboration was associated with improved database search quality, search reproducibility, and systematic review reporting in otolaryngology systematic reviews and meta-analyses., Methods: In this retrospective cross-sectional study, PubMed was queried for systematic reviews and meta-analyses published in otolaryngology journals in 2010, 2015, and 2021. Two researchers independently extracted data. Two librarians independently rated search strategy reproducibility and quality for each article. The main outcomes include association of librarian involvement with study reporting quality, search quality, and publication metrics in otolaryngology systematic reviews and meta-analyses. Categorical data were compared with Chi-Squared tests or Fisher's Exact tests. Continuous variables were compared via Mann Whitney U Tests for two groups, and Kruskal-Wallis Tests for three or more groups., Results: Of 559 articles retrieved, 505 were analyzed. More studies indicated librarian involvement in 2021 (n=72, 20.7%) compared to 2015 (n=14, 10.4%) and 2010 (n=2, 9.0%) (p=0.04). 2021 studies showed improvements in properly using a reporting tool (p<0.001), number of databases queried (p<0.001), describing date of database searches (p<0.001), and including a flow diagram (p<0.001). Librarian involvement was associated with using reporting tools (p<0.001), increased number of databases queried (p<0.001), describing date of database search (p=0.002), mentioning search peer reviewer (p=0.02), and reproducibility of search strategies (p<0.001). For search strategy quality, librarian involvement was associated with greater use of "Boolean & proximity operators" (p=0.004), "subject headings" (p<0.001), "text word searching" (p<0.001), and "spelling/syntax/line numbers" (p<0.001). Studies with librarian involvement were associated with publication in journals with higher impact factors for 2015 (p=0.003) and 2021 (p<0.001)., Conclusion: Librarian involvement was associated with improved reporting quality and search strategy quality. Our study supports the inclusion of librarians in review teams, and journal editing and peer reviewing teams., Competing Interests: The authors declare that there is no conflict of interest., (Copyright © 2024 Rachel Whitney, Michael C.

Background: The placebo effect observed in clinical trials evaluating medical treatments for chronic rhinosinusitis (CRS) is not well understood. This systematic review and meta-analysis sought to characterize the placebo effect present within CRS outcomes., Methods: A systematic review of PubMed, Scopus, and Cumulated Index in Nursing and Allied Health Nursing (CINAHL) was performed. Randomized controlled trials (RCTs) evaluating medical treatments for CRS versus placebo were included. We assessed patient-reported (sino-nasal outcome test 22 [SNOT-22], nasal obstruction, sense of smell, nasal obstruction visual analogue score [VAS], sense of smell VAS, anterior rhinorrhea, and postnasal drip) and objective (Lund-Mackay Computed tomography (CT) score, peak nasal inspiratory flow [PNIF], nasal polyp scores, 40-item Smell Identification Test, serum IgE, and blood eosinophil levels) outcomes., Results: Twenty-one RCTs were included, comprising 1437 patients (mean age 49.2 years). Biologics were the most common treatment investigated (n = 9). Eleven studies administered background steroids along with placebo. Following placebo administration, multiple patient-reported outcomes significantly decreased, including SNOT-22 (mean difference -9.49, 95% confidence interval [CI] [-11.26, -7.73]), nasal obstruction (-0.33 [-0.54, -0.13]), sense of smell (-0.22 [-0.33, -0.11]), nasal obstruction VAS (-2.47 [-2.87, -2.06]), and loss of smell VAS (-2.31 [-4.14, -0.47]) scores. For objective measures, significant changes occurred in Lund-Mackay CT score (-0.82, [-1.48, -0.16]) and PNIF (4.70, [4.76, 24.64]) with placebo. Placebo arms had the greatest impact when no background medications were used., Conclusions: Placebo treatments have a statistically and potentially clinically significant effect on patient-reported and some objective CRS outcomes. Further investigation is required to fully understand placebo effect, which could improve assessment of RCTs and impact patient care., (© 2023 ARS-AAOA, LLC.)

Objective: Initiating postoperative radiotherapy (PORT) within 6 weeks (42 days) of surgery is the first and only Commission on Cancer (CoC) approved quality metric for head and neck squamous cell carcinoma (HNSCC). No study has systematically reviewed nor synthesized the literature to establish national benchmarks for delays in starting PORT., Data Sources: Following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we performed a systematic review of PubMed, Scopus, and CINAHL., Review Methods: Studies that described time-to-PORT or PORT delays in patients with HNSCC treated in the United States after 2003 were included. Meta-analysis of proportions and continuous measures was performed on nonoverlapping datasets to examine the pooled frequency of PORT delays and time-to-PORT., Results: Thirty-six studies were included in the systematic review and 14 in the meta-analysis. Most studies utilized single-institution (n = 17; 47.2%) or cancer registry (n = 16; 44.4%) data. Twenty-five studies (69.4%) defined PORT delay as >6 weeks after surgery (the definition utilized by the CoC and National Comprehensive Cancer Network Guidelines), whereas 4 (11.1%) defined PORT delay as a time interval other than >6 weeks, and 7 (19.4%) characterized time-to-PORT without defining delay. Meta-analysis revealed that 48.6% (95% confidence interval [CI], 41.4-55.9) of patients started PORT > 6 weeks after surgery. Median and mean time-to-PORT were 45.8 (95% CI, 42.4-51.4 days) and 47.4 days (95% CI, 43.4-51.4 days), respectively., Conclusion: Delays in initiating guideline-adherent PORT occur in approximately half of patients with HNSCC. These meta-analytic data can be used to set national benchmarks and assess progress in reducing delays., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

A biliary stricture is an abnormal narrowing in the ductal drainage system of the liver that can result in clinically and physiologically relevant obstruction to the flow of bile. The most common and ominous etiology is malignancy, underscoring the importance of a high index of suspicion in the evaluation of this condition. The goals of care in patients with a biliary stricture are confirming or excluding malignancy (diagnosis) and reestablishing flow of bile to the duodenum (drainage); the approach to diagnosis and drainage varies according to anatomic location (extrahepatic vs perihilar). For extrahepatic strictures, endoscopic ultrasound-guided tissue acquisition is highly accurate and has become the diagnostic mainstay. In contrast, the diagnosis of perihilar strictures remains a challenge. Similarly, the drainage of extrahepatic strictures tends to be more straightforward and safer and less controversial than that of perihilar strictures. Recent evidence has provided some clarity in multiple important areas pertaining to biliary strictures, whereas several remaining controversies require additional research. The goal of this guideline is to provide practicing clinicians with the most evidence-based guidance on the approach to patients with extrahepatic and perihilar strictures, focusing on diagnosis and drainage., (Copyright © 2023 by The American College of Gastroenterology.)

Caregivers of adults with cancer often provide prolonged demanding assistance (e.g., physical, emotional) to their loved ones, resulting in caregiver burden. This meta-analytic review examined the efficacy of psychosocial interventions in reducing caregiver burden in caregivers of adults with cancer. Randomized controlled trials (RCTs) were identified from six electronic databases and clinical trial registries. Random-effects meta-analyses were conducted for subgroups of interventions and control conditions. Overall, 90 records describing 50 RCTs showed that psychosocial interventions reduced caregiver burden compared to passive controls (e.g. wait-list) at post-intervention (g = 0.26, 95%CI [0.12, 0.40]), but not at the first follow-up (g = 0.10, 95%CI [-0.05, 0.24]). Subgroup analyses showed that compared to passive controls, therapeutic counseling and skills training interventions significantly reduced caregiver burden at post-intervention, whereas psycho-education/support interventions did not significantly reduce burden. Very few RCTs examined intervention efficacy compared to active controls (e.g., psycho-education/support). The evidence grade ranged from very low to moderate due to inconsistency and imprecision of the results. Therapeutic counseling and skills training interventions appear efficacious in improving caregiver burden at post-intervention, although these improvements attenuate over time. Rigorous trials examining intervention effects on long-term outcomes are needed to better understand the effective mechanisms to sustain reduction in caregiver burden., Competing Interests: Declaration of Competing Interest Ekin Secinti is presently employed at Eli Lilly and Company, Indianapolis, IN.

Introduction: Temporal bone osteomyelitis is an invasive infection most often caused by bacteria and associated with high mortality. Fungal etiologies are rare and little is known of the predictors of disease severity and outcomes in fungal temporal bone osteomyelitis., Materials and Methods: A scoping review was performed to determine what is known from the literature on how clinical, diagnostic, and treatment characteristics relate to patient outcomes in fungal temporal bone osteomyelitis. Using PRISMA guidelines, three databases were searched to identify all published cases of fungal temporal bone osteomyelitis. Data were extracted from each study, including clinical, diagnostic, and treatment characteristics, and outcomes., Results: Sixty-eight studies comprising 74 individual cases of fungal temporal bone osteomyelitis were included. All studies were case reports. There were high rates of diabetes, facial nerve palsy, infectious complications, and need for surgical intervention, as well as a significant delay in the evaluation and diagnosis of fungal temporal bone osteomyelitis. Disease recovery was greater in patients presenting with otorrhea, comorbid diabetes, and in those without facial nerve palsy., Discussion: Many of the defining characteristics of fungal temporal bone osteomyelitis remain unknown, and future reports should focus on determining factors that improve timely diagnosis and treatment of fungal TBO in addition to identifying prognostic indicators for outcomes and survival., Competing Interests: The authors disclose no conflicts of interest., (Copyright © 2022, Otology & Neurotology, Inc.)

Introduction: During the SARS-CoV-2 pandemic, the incidence of pediatric button battery (BB) ingestions has risen. Children have spent more time at home from school, while many parents try to balance working from home and childcare. Additionally, the amount of electronics powered by BB has increased. Tracheoesophageal fistula (TEF) secondary to a retained aerodigestive BB is a devastating development. Management is challenging, and the clinical timeline of watchful waiting versus surgical intervention for TEF is poorly defined in the literature., Methods: In accordance with PRISMA guidelines, databases searched include PubMed, Scopus, and CINAHL from database date of inception through August 13, 2021. All study designs were included, and no language, publication date, or other restrictions were applied. Case series and reports of TEFs secondary to BBs were included. Clinical risk factors and outcomes were compared between the spontaneous closure and surgical repair groups., Results: A total of 79 studies with 105 total patients were included. Mortality was 11.4%. There were 23 (21.9%) TEFs that spontaneously closed and 71 (67.6%) that underwent surgical repair. Median time to spontaneous closure compared to surgical repair was significantly different (8.0 weeks [IQR 4.0-18.4] vs. 2.0 weeks [IQR 0.1-3.3], p<0.001). Smaller TEFs were more likely to spontaneously close versus being surgically repaired (9.3 mm ± 3.5 vs. 14.9 mm ± 8.3, p=0.022). Duration of symptoms before BB discovery, BB size, time between BB removal and TEF discovery, and location of the TEF were not statistically different between the spontaneous closure and surgical repair groups., Conclusion: A TEF secondary to BB ingestion is a potentially deadly complication. Timing of reported TEF spontaneous closure varies significantly. While smaller TEFs may be amenable to healing without surgical repair, no other significant factors were identified that may be associated with spontaneous closure. If clinical status permits, these data suggest a period of observation of at least 8 weeks prior to surgical intervention may be practical for many BB-induced TEFs., (Copyright © 2022 Elsevier B.V.

Background: Postoperative pericardial adhesions have been associated with increased morbidity, mortality, and surgical difficulty. Barriers exist to limit adhesion formation, yet little is known about their use in cardiac surgery. The study presented here provides the first major systematic review of adhesion barriers in cardiac surgery., Methods: Scopus and PubMed were assessed on November 20, 2020. Inclusion criteria were clinical studies on human subjects, and exclusion criteria were studies not published in English and case reports. Risk of bias was evaluated with the Cochrane Risk of Bias Tool. Barrier efficacy data was assessed with Excel and GraphPad Prism 5., Results: Twenty-five studies were identified with a total of 13 barriers and 2928 patients. Polytetrafluoroethylene (PTFE) was the most frequently evaluated barrier (13 studies, 67% of patients) with adhesion formation rate of 37.31% and standardized tenacity score of 26.50. Several barriers had improved efficacy. In particular, Cova CARD had a standardized tenacity score of 15.00., Conclusions: Overall, the data varied considerably in terms of study design and reporting bias. The amount of data was also limited for the non-PTFE studies. PTFE has historically been effective in preventing adhesions. More recent barriers may be superior, yet the current data is nonconfirmatory. No ideal adhesion barrier currently exists, and future barriers must focus on the requirements unique to operating in and around the heart., (© 2021 Wiley Periodicals LLC.)

Background: Viral respiratory infections are a leading cause of worldwide mortality and exert the potential to cause global socioeconomic crises. However, inexpensive, efficacious, and rapidly deployable strategies to reduce viral transmission are increasingly important in the setting of an ongoing pandemic, though not entirely understood. This article provides a comprehensive review of commonly employed nonpharmacological interventions to interrupt viral spread and provides evidence-based recommendations for their use., Methodology: A systematic review of three databases was performed. Studies with defined endpoints of subjects receiving one of five interventions (nasal washing, gargling, personal protective equipment (PPE), social distancing, and hand hygiene) were included. An evidence-based review of the highest level of evidence, with recommendations, was created in accordance with a previously described, rigorous, iterative process., Results: Fifty-four primary studies were included. The most commonly studied intervention was hand hygiene, followed by PPE, gargling, saline nasal washing, and social distancing., Conclusions: Mask use and hand hygiene are strong recommendations for prevention of viral transmission. Donning gloves, gowns, and eye protection are a recommendation in healthcare settings. Saline nasal washing and gargling are options in selected populations. Although an aggregate level of evidence is not provided, the authors recommend social distancing.

Objective: This study aims to explore and determine the effectiveness of current pharmacologic agents for the prevention of noise-induced hearing loss (NIHL) via a systematic review., Databases Reviewed: The PubMed, Scopus, ClinicalTrials.gov, and Cochrane Library databases were searched from inception through February 6, 2020., Methods: Full-text, English-language articles detailing prospective randomized and nonrandomized clinical trials with pharmacological interventions administered to prevent NIHL were included in accordance with PRISMA guidelines. The detailed search terms are included in the Appendix, http://links.lww.com/MAO/B67., Results: Eleven articles were included in this review with 701 patients receiving a pharmacologic prevention for various noise exposures. Various regimens included administration of alpha-lipoic acid, ambient oxygen, beta-carotene, carbogen, ebselen, Mg-aspartate, N-acetylcysteine, and vitamins C, E, and B12. A number of studies demonstrated statistically significant amelioration of NIHL with pharmacologic intervention. Two studies demonstrated significantly better hearing outcomes for pharmacological prophylaxis with carbogen or ebselen as compared with placebo for the 4 kHz frequency, where the noise-notch is most likely to be encountered. Given the considerable heterogeneity in agents and methodologies, however, it was not possible to conduct a meta-analysis., Conclusions: While several heterogenous articles demonstrated promising results for Mg-aspartate, carbogen, vitamin B12, and alpha-lipoic acid, the clinical significance of these pharmaceuticals remains unclear. Initial data from this study alongside future clinical trials might potentially contribute to the generation of clinical practice guidelines to prevent NIHL., Level of Evidence: 2.

Objective: To assess the effects of earlier vs. later re-initiation of enteral feeds after necrotizing enterocolitis (NEC)., Study Design: We reviewed the literature to assess timing of enteral feeding after NEC using fixed effects models., Results: Three studies met inclusion criteria; no randomized trials. After removal of Bell's Stage I infants, the earlier refeeding group (<5-7 or median 4 days) included 79 infants and later refeeding group (≥5-7 or median 10 days) included 119 infants. Pooled analysis revealed earlier re-initiation reduced the incidence in the composite outcome of recurrent NEC and/or post-NEC stricture (OR = 0.27; 95% Cl = 0.10-0.75; p = 0.012). Individually, NEC recurrence (pooled OR = 0.34; 95% Cl = 0.09-1.29; p = 0.112) or stricture (OR = 0.34; 95% Cl = 0.09-1.26; p = 1.06) did not differ between groups., Conclusions: There was no increase in negative outcomes with earlier refeeding after NEC. Earlier initiation of enteral feeds resulted in a significantly lower risk for the combined outcome of recurrent NEC and/or post-NEC stricture.

Background: Librarians teach evidence-based medicine (EBM) and information-seeking principles in undergraduate, graduate, and post-graduate medical education. These curricula are informed by medical education standards, medical education competencies, information literacy frameworks, and background literature on EBM and teaching. As this multidimensional body of knowledge evolves, librarians must adapt their teaching and involvement with medical education. Identifying explicit connections between the information literacy discipline and the field of medical education requires ongoing attention to multiple guideposts but offers the potential to leverage information literacy skills in the larger health sciences education sphere., Methods: A subgroup of the Association of Academic Health Sciences Libraries Competency-Based Medical Education Task Force cross-referenced medical education documents (Core Entrustable Professional Activities and 2017-2018 Liaison Committee on Medical Education Functions and Structures of a Medical School) with the Association of College & Research Libraries Framework for Information Literacy for Higher Education using nominal group technique., Results: In addition to serving as a vocabulary, the map can also be used to identify gaps between and opportunities for enhancing the scholarly expectations of undergraduate and graduate medical education standards and the building blocks of information literacy education., (Copyright © 2020 Emily A.

Objective: To synthesize published literature describing the severity of body image disturbance (BID) in patients with head and neck cancer (HNC) over time, its psychosocial and functional associations, and treatment strategies as assessed by patient-reported outcome measures (PROMs)., Data Source: PubMed/MEDLINE, Scopus, PsycINFO, Web of Science, and Google Scholar., Review Methods: A systematic review of the English-language literature was performed to identify studies of BID in patients with HNC using psychometrically validated PROMs to assess (1) severity of BID over time, (2) psychosocial and functional associations, and (3) management strategies., Results: A total of 17 studies met inclusion criteria. BID was assessed via 10 different PROMs, none of which were HNC-specific measures of BID. Two of 2 longitudinal studies (100%) reported that BID improved from pretreatment to posttreatment, and 2 of 3 longitudinal studies (67%) showed that the severity of BID decreased over time as survivors got further out from treatment. Seven of 17 studies (41%) described negative functional and psychosocial associations with BID, although study methodology limited conclusions about cause and effect. None of the studies assessing interventions to manage BID (0/2, 0%) demonstrated an improvement in BID relative to control., Conclusion: BID in patients with HNC has negative functional and psychosocial associations and lacks evidence-based treatment. Research is limited by the lack of an HNC-specific BID PROM. Further research should address knowledge gaps related to the lack of an HNC-specific BID PROM, longitudinal course of BID in patients with HNC, confusion with regards to risk factors and outcomes, and lack of prevention and treatment strategies.

Background: Individual randomized controlled trials (RCTs) have demonstrated the efficacy of cognitive behavioral therapy (CBT) and serotonin reuptake inhibitors (SRIs) for the treatment of youth with obsessive-compulsive disorder (OCD). Although meta-analyses have confirmed these results, there has been minimal examination of treatment moderators or an examination of treatment response and symptom/diagnostic remission for these two treatment types. The present report examined the treatment efficacy, treatment response, and symptom/diagnostic remission for youth with OCD receiving either CBT or SRIs relative to comparison conditions, and examined treatment moderators., Method: A comprehensive literature search identified 20 RCTs that met inclusion criteria, and produced a sample size of 507 CBT participants and 789 SRI participants., Results: Random effects meta-analyses of CBT trials found large treatment effects for treatment efficacy (g = 1.21), treatment response (relative risk [RR] = 3.93), and symptom/diagnostic remission (RR = 5.40). Greater co-occurring anxiety disorders, therapeutic contact, and lower treatment attrition were associated with greater CBT effects. The number needed to treat (NNT) was three for treatment response and symptom/diagnostic remission. Random effects meta-analyses of SRI trials found a moderate treatment effect for treatment efficacy (g = 0.50), treatment response (RR = 1.80), and symptom/diagnostic remission (RR = 2.06). Greater methodological quality was associated with a lower treatment response for SRI trials. The NNT was five for treatment response and symptom/diagnostic remission., Conclusions: Findings demonstrate the treatment effects for CBT and SRIs across three important outcome metrics, and provide evidence for moderators of CBT across trials., (© 2015 Wiley Periodicals, Inc.)

Individual randomized controlled trials (RCTs) of habit reversal training and a Comprehensive Behavioral Intervention for Tics (collectively referred to as behavior therapy, BT) have demonstrated efficacy in reducing tic severity for individuals with Tourette Syndrome and Chronic Tic Disorders (collectively referred to as TS), with no examination of treatment moderators. The present meta-analysis synthesized the treatment effect sizes (ES) of BT relative to comparison conditions, and examined moderators of treatment. A comprehensive literature search identified eight RCTs that met inclusion criteria, and produced a total sample of 438 participants. A random effects meta-analysis found a medium to large ES for BT relative to comparison conditions. Participant mean age, average number of therapy sessions, and the percentage of participants with co-occurring attention deficit hyperactivity disorder (ADHD) were found to moderate treatment effects. Participants receiving BT were more likely to exhibit a treatment response compared to control interventions, and identified a number needed to treat (NNT) of three. Sensitivity analyses failed to identify publication bias. Overall, BT trials yield medium to large effects for TS that are comparable to treatment effects identified by meta-analyses of antipsychotic medication RCTs. Larger treatment effects may be observed among BT trials with older participants, more therapeutic contact, and less co-occurring ADHD., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

The mechanism of acetate absorption in the small intestine is not yet established. One possible mechanism is by carrier mediated Na(+)-acetate cotransport since acetate, like glucose, stimulates intestinal Na+ and water absorption in vivo. Uptake of radioactive carbon acetate by small intestinal brush border membrane vesicles was not saturable or Na+ dependent and did not respond to osmotic shrinkage of the vesicles. This suggests that acetate binds to the membranes but is not transported into the intravesicular space and argues against carrier mediated Na+ acetate cotransport. These results are consistent with acetate absorption by a non-mediated diffusion and suggest that the stimulation of water and Na+ absorption by acetate in vivo is largely due to osmotic forces and solvent drag.
