The Use of Race and Socioeconomic Status Variables in Published Otolaryngologic Research.

OBJECTIVE: To characterize the use of race and socioeconomic status (SES) variables in clinical otolarynogologic research. METHODS: Databases were queried for all articles published in 2016 issues of 5 major otolaryngologic journals. One thousand, one hundred and forty of 1593 articles abstracted met inclusion criteria for analysis. RESULTS: In total, 244 (21.4%) studies specified race as a variable. The subspecialty of Head and Neck cancer specified race at statistically higher rates compared to other subspecialties (P = .002). Two hundred nine (34.0%) domestic studies specified race compared to 35 (6.7%) international studies. Of the 244 studies that specified race, 79 (32.4%) defined race using racial and ethnic categories interchangeably. Two hundred twenty-four (91.8%) studies reported data by race, 145 (59.4%) analyzed the data, and 112 (45.9%) discussed race-based results.In total, 94 (8.2%) studies specified SES. All subspecialties specified SES at statistically similar rates. Seventy (11.4%) domestic studies specified SES compared to 24 (4.6%) international studies. Of the 94 studies that specified SES, 42 (44.7%) defined SES using insurance status, 35 (37.2%) used education, and 32 (34.0%) used income. Seventy-eight (83.0%) studies reported data by SES, 71 (75.5%) analyzed the data, and 68 (72.3%) discussed SES-based results. CONCLUSION: In clinical otolaryngologic research, the study of race and SES is limited. To improve quality of research and patient care for all patients, investigators should clearly justify their use of race and SES variables, carefully select their measures of race and SES (if the use of these variables is justified), and study race/SES-based data beyond just a superficial level.

Internet and social media research by parents of pediatric otolaryngologic patients.

PURPOSE: Public access to medical information has increased dramatically with the growth and accessibility of the Internet. The goal of this study is to characterize how parents use the Internet to understand and make decisions about their child's otolaryngologic surgery. MATERIALS AND METHODS: A survey was distributed to parents of pediatric patients undergoing otolaryngologic procedures to assess if and how parents gather information about their child's surgery. RESULTS: 105 parents completed the survey. 59.4% of parents gathered online information about their child's surgery. 86% of these parents used Google, 36% used YouTube, 16% used Wikipedia, and 9% used a hospital website. Most searched for general information about the surgery, followed by risks, pain/recovery, and specifics about the surgery. 69% reported that the information found influenced the healthcare decisions they made for their child. 86% felt the information was trustworthy. 21% discussed the information with their child's surgeon. 17% gathered information about their child's surgeon, of which 73% were interested in the surgeon's experience. 69% reported this influenced their choice of surgeon. CONCLUSIONS: Most parents of pediatric otolaryngologic patients use the Internet to gather information about their child's surgery, view that information as accurate, and use that information to make healthcare decisions. However, less than one quarter of parents discuss the information with their child's surgeon. It is critical to understand how parents use the Internet for healthcare information so otolaryngologists can better direct their patients' parents to appropriate and accurate resources.

Opioid use in pediatric otolaryngologic surgery: A survey of caregivers' attitudes.

OBJECTIVE: Given the current opioid epidemic and the fact that children continue to be undertreated for pain following surgeries, it is important to understand care-givers' attitudes toward post-operative opioid use. DESIGN: A survey was distributed to caregivers of pediatric patients undergoing otolaryngologic procedures. SETTING: An academic hospital in Boston, Massachusetts. PARTICIPANTS: Sixty-eight caregivers completed the survey. MAIN OUTCOME MEASURE: Caregiver attitudes toward post-operative opioid use. RESULTS: The study results are as follows: 38.1 percent of parents stated they would feel comfortable giving their child opioids post-operatively, 30.2 percent would not feel comfortable, and 31.7 percent were unsure. For every increase in 1 year of age of the child, there was an increase in the odds of a parent being comfortable giving opioids. Caregivers who had taken opioids in the past were more likely to feel comfortable, while those who were employed were less likely to feel comfortable. The most common reason reported for not feeling comfortable was addiction potential. The comfort level did not differ based on the caregivers' education level, income, race, or language. CONCLUSION: The majority of caregivers are unsure about or do not feel comfortable giving their child opioids post-operatively. Most are specifically concerned about the risk of addiction. Understanding caregivers' views on opioids in a diverse patient population is essential, so surgeons can counsel caregivers and provide appropriate post-operative pain management in their patients.

Parental Views on the Role of Social Media in Pediatric Otolaryngology.

OBJECTIVE: Social media is playing an increasingly important role in medicine as a tool for patients and their families to find information and connect with others. The goal of this study is to understand parental views on if and how social media should be incorporated into pediatric otolaryngology by physicians and hospitals. METHODS: A survey was distributed to parents of pediatric otolaryngologic patients to assess views on professional social media use by physicians and hospitals. The proportion of parents who answered with specific responses in the survey was computed using the SPSS frequency analysis function. RESULTS: One hundred five parents completed the survey. Ninety-six percent of respondents use social media, of which 92% use social media at least once a day (n = 93). Eighty-five percent of respondents said they definitely or probably would visit their physician's professional social media page (n = 90). Seventy-four percent would be interested in obtaining more information about the physician (n = 76). Forty-one percent would be interested in patient stories (n = 76). Twenty-eight percent would visit out of curiosity (n = 76). Twenty-six percent would want to gather more information about the hospital (n = 76). Seventeen percent would want to connect with other patients and their family members (n = 76). Sixty-seven percent of respondents believe it is important for physicians to have a professional social media page, and 79% of respondents believe it is important for hospitals to have a public social media page (n = 93). CONCLUSION: The vast majority of parents of pediatric otolaryngologic patients use social media regularly and would want to gather information about their physician and hospital through social media. Therefore, physicians and hospitals should consider using social media as a valuable tool to connect with and relay information to patients and their family members.

Novel treatment for mild and moderate velopharyngeal insufficiency using implantable AlloDerm for posterior pharyngeal wall augmentation and review of surgical repair techniques.

PURPOSE: Mild and moderate velopharyngeal insufficiency is a relatively common structural defect of the velopharyngeal sphincter that occurs congenitally or secondarily to various medical conditions resulting in speech inadequacy. Currently, multiple surgical methods exist to treat mild and moderate velopharyngeal insufficiency; however, the revision rates are high and the outcomes are variable. This case series describes a novel technique using implantable AlloDerm to repair the posterior pharyngeal wall to treat mild and moderate velopharyngeal insufficiency. MATERIALS AND METHODS: This paper presents four patients with mild or moderate velopharyngeal insufficiency who were treated with implantable AlloDerm in the posterior pharyngeal wall at a large, safety-net hospital in New England from 2000 to 2019. Additionally, a review of surgical repair techniques for velopharyngeal insufficiency was conducted with synthesis of a qualitative overview. RESULTS: There were sufficient follow-up data in three of these patients. All three reported subjective improvements in symptoms after the procedure. One patient had implant extrusion one month following the procedure with subsequent removal. CONCLUSION: Ultimately, implantable AlloDerm for posterior pharyngeal wall augmentation is a useful, low risk method for treating mild to moderate velopharyngeal insufficiency.

Association Between Preoperative Malnutrition and Postoperative Delirium After Hip Fracture Surgery in Older Adults.

OBJECTIVES: To determine whether poor nutritional status can predict postoperative delirium in elderly adults undergoing hip fracture surgery. DESIGN: Prospective observational cohort study. SETTING: Italian orthogeriatric unit. PARTICIPANTS: Individuals aged 70 and older (mean age 84.0 ± 6.6, 74.5% female) consecutively admitted for surgical repair of a proximal femur fracture between September 2012 and April 2016 (N = 415). MEASUREMENTS: Participants underwent a comprehensive geriatric assessment including nutritional status, which was evaluated using the Mini Nutritional Assessment Short Form (MNA-SF). The MNA-SF-based three-class stratification was tested using multivariable logistic regression to assess its role in predicting postoperative delirium (outcome). RESULTS: Seventy-eight malnourished individuals (MNA-SF score 0-7), 185 at risk of malnutrition (MNA-SF score 8-11), and 152 who were well nourished (MNA-SF score 12-14) were compared. On average, individuals with poor nutritional status were more disabled and more cognitively impaired than those who were well nourished and those at risk of malnutrition. Moreover, those who were malnourished were more likely to have postoperative delirium. Multivariate regression analysis adjusted for age, sex, comorbidity, functional impairment, preoperative cognitive status, and American Society of Anesthesiologists score showed that those who were at risk of malnutrition (odds ratio (OR) = 2.42, 95% confidence interval (CI) = 1.29-4.53) and those who were overtly malnourished (OR = 2.98, 95% CI = 1.43-6.19) were more likely to develop postoperative delirium. CONCLUSION: This is the first study in a Western population showing that risk of malnutrition and overt malnutrition, as assessed using the MNA-SF, are independent predictors of postoperative delirium. Accordingly, nutritional status should be assessed in individuals with hip fracture before surgery to determine risk of developing delirium.

Extracellular Tau Paired Helical Filaments Differentially Affect Tau Pathogenic Mechanisms in Mitotic and Post-Mitotic Cells: Implications for Mechanisms of Tau Propagation in the Brain.

The release of paired helical filaments (PHFs) from neurons into the extracellular space may contribute to the propagation of tau pathology across brain regions in Alzheimer's disease (AD) and other tauopathies. The majority of available mechanistic studies exploring the pathologic role of extracellular PHFs are conducted in proliferating cell lines. Here, we compare how extracellular PHFs induce tauopathy in mitotic cells and in post-mitotic brain neurons. In a mitotic cell line (HEK 293T), extracellular exposure to AD PHFs leads to an intracellular "aggresomal" type deposition of tau, coincidental with redistribution of dynein, a retrograde motor protein. We also observed that PHFs impaired proteasome degradation, but not autophagy. Exposure of cells to proteasome inhibitors was sufficient to induce intracellular tau aggregate formation as well as reorganization of dynein and the intermediate filament protein, vimentin. Thus, in mitotic cells, extracellular PHFs promote cellular tau aggregation, in part, by interfering with cellular proteasome degradation processes. In contrast with our observations with proliferating cells, exposure of post-mitotic primary neuronal cultures to AD PHFs did not promote "aggresomal" tau deposition, but instead resulted in a widespread accumulation of phosphorylated tau-immunoreactive swellings in neuritic processes, characterized by disturbed cytoskeletal organization of dynein and vimentin. Collectively, our observations suggest that extracellular PHFs may contribute to the propagation of tau pathology by independent mechanisms in post-mitotic and mitotic brain cells. These outcomes indicate that in addition to post-mitotic brain neurons, mitotic brain cells should also be considered as targets for therapeutic interventions to attenuate propagation of tauopathy.

Recommendations for Development of Botanical Polyphenols as "Natural Drugs" for Promotion of Resilience Against Stress-Induced Depression and Cognitive Impairment.

Extensive evidence has demonstrated that psychological stress has detrimental effects on psychological health, cognitive function, and ultimately well-being. While stressful events are a significant cause of psychopathology, most individuals exposed to adversity maintain normal psychological functioning. The mechanisms underlying such resilience are poorly understood, and there is an urgent need to identify and target these mechanisms to promote resilience under stressful events. Botanicals have been used throughout history to treat various medical conditions; however, the development of botanical compounds into potential preventative and therapeutic agents in studies promoting brain health is hindered by the fact that most orally consumed botanicals are extensively metabolized during absorption and/or by post-absorptive xenobiotic metabolism. Therefore, the primary objective of this review article is to provide recommendations for developing natural compounds as novel therapeutic strategies to promote resilience in susceptible subjects. The development of botanical polyphenols to ultimately attenuate mood disorders and cognitive impairment will rely on understanding (1) the absorption and bioavailability of botanical polyphenols with emphasis on flavan-3-ols, (2) the characterization of tissue-specific accumulation of biologically available polyphenols and their mechanisms of action in the brain, and eventually (3) the characterization of biologically available polyphenol metabolites in mechanisms associated with the promotion of resilience against mood disorders and cognitive impairment in response to stress. We also summarize exciting new lines of investigation about the role of botanicals such as polyphenols in the promotion of cognitive and psychological resilience. This information will provide a strategical framework for the future development of botanicals as therapeutic agents to promote resilience, ultimately preventing and/or therapeutically treating cognitive impairment and psychological dysfunction.

Biomarkers of Resilience in Stress Reduction for Caregivers of Alzheimer's Patients.

Caregiving for a dementia patient is associated with increased risk of psychological and physical health problems. We investigated whether a mindfulness-based stress reduction (MBSR) training course for caregivers that closely models the MBSR curriculum originally established by the Center of Mindfulness at the University of Massachusetts may improve the psychological resilience of non-professional caregivers of Alzheimer's disease patients. Twenty adult non-professional caregivers of dementia patients participated in an 8-week MBSR training course. Caregiver stress, depression, burden, grief, and gene expression profiles of blood mononuclear cells were assessed at baseline and following MBSR. MBSR training significantly improved the psychological resilience of some of the caregivers. We identified predictive biomarkers whose expression is associated with the likelihood of caregivers to benefit from MBSR, and biomarkers whose expression is associated with MBSR psychological benefits. Our biomarker studies provide insight into the mechanisms of health benefits of MBSR and a basis for developing a personalized medicine approach for applying MBSR for promoting psychological and cognitive resilience in caregivers of dementia patients.

In Silico Modeling of Novel Drug Ligands for Treatment of Concussion Associated Tauopathy.

The objective of this study was to develop an in silico screening model for characterization of potential novel ligands from commercial drug libraries able to functionally activate certain olfactory receptors (ORs), which are members of the class A rhodopsin-like family of G protein couple receptors (GPCRs), in the brain of murine models of concussion. We previously found that concussions may significantly influence expression of certain ORs, for example, OR4M1 in subjects with a history of concussion/traumatic brain injury (TBI). In this study, we built a 3-D OR4M1 model and used it in in silico screening of potential novel ligands from commercial drug libraries. We report that in vitro activation of OR4M1 with the commercially available ZINC library compound 10915775 led to a significant attenuation of abnormal tau phosphorylation in embryonic cortico-hippocampal neuronal cultures derived from NSE-OR4M1 transgenic mice, possibly through modulation of the JNK signaling pathway. The attenuation of abnormal tau phosphorylation was rather selective since ZINC10915775 significantly decreased tau phosphorylation on tau Ser202/T205 (AT8 epitope) and tau Thr212/Ser214 (AT100 epitope), but not on tau Ser396/404 (PHF-1 epitope). Moreover, no response of ZINC10915775 was found in control hippocampal neuronal cultures derived from wild type littermates. Our in silico model provides novel means to pharmacologically modulate select ubiquitously expressed ORs in the brain through high affinity ligand activation to prevent and eventually to treat concussion induced down regulation of ORs and subsequent cascade of tau pathology.

Selective brain penetrable Nurr1 transactivator for treating Parkinson's disease.

Parkinson's disease (PD) is one of the most common movement disorders, and currently there is no effective treatment that can slow disease progression. Preserving and enhancing DA neuron survival is increasingly regarded as the most promising therapeutic strategy for treating PD. IRX4204 is a second generation retinoid X receptor (RXR) agonist that has no cross reactivity with retinoic acid receptors, farnesoid X receptor, liver X receptors or peroxisome proliferator-activated receptor PPARγ. We found that IRX4204 promotes the survival and maintenance of nigral dopaminergic (DA) neurons in a dose-dependent manner in primary mesencephalic cultures. Brain bioavailability studies demonstrate that IRX4204 can cross the blood brain barrier and reach the brain at nM concentration. Oral administration of IRX4204 can activate nuclear receptor Nurr1 downstream signaling in the substantia nigra (SN) andattenuate neurochemical and motor deficits in a rat model of PD. Our study suggests that IRX4204 represents a novel, potent and selective pharmacological means to activate cellular RXR-Nurr1 signaling and promote SN DA neuron survival in PD prevention and/or treatment.

Recommendations for Development of New Standardized Forms of Cocoa Breeds and Cocoa Extract Processing for the Prevention of Alzheimer's Disease: Role of Cocoa in Promotion of Cognitive Resilience and Healthy Brain Aging.

It is currently thought that the lackluster performance of translational paradigms in the prevention of age-related cognitive deteriorative disorders, such as Alzheimer's disease (AD), may be due to the inadequacy of the prevailing approach of targeting only a single mechanism. Age-related cognitive deterioration and certain neurodegenerative disorders, including AD, are characterized by complex relationships between interrelated biological phenotypes. Thus, alternative strategies that simultaneously target multiple underlying mechanisms may represent a more effective approach to prevention, which is a strategic priority of the National Alzheimer's Project Act and the National Institute on Aging. In this review article, we discuss recent strategies designed to clarify the mechanisms by which certain brain-bioavailable, bioactive polyphenols, in particular, flavan-3-ols also known as flavanols, which are highly represented in cocoa extracts, may beneficially influence cognitive deterioration, such as in AD, while promoting healthy brain aging. However, we note that key issues to improve consistency and reproducibility in the development of cocoa extracts as a potential future therapeutic agent requires a better understanding of the cocoa extract sources, their processing, and more standardized testing including brain bioavailability of bioactive metabolites and brain target engagement studies. The ultimate goal of this review is to provide recommendations for future developments of cocoa extracts as a therapeutic agent in AD.
