The Microbiology Of Acute Exacerbations In Chronic Rhinosinusitis - A Systematic Review, Oghenefejiro Okifo, Amrita Ray, David A. Gudis

Otolaryngology Articles

BACKGROUND: Acute exacerbations (AE) in chronic rhinosinusitis (CRS) are a common and important clinical issue. However, relatively little is known regarding the underlying microbiology that drives exacerbations or how it relates to the microbiome of CRS. The purpose of this study is to examine the literature to characterize the microbiome associated with acute exacerbations in a chronic rhinosinusitis setting. Understanding this disease process may facilitate targeted antibiotic therapy, reduced antibiotic resistance, and offer more effective disease control and treatment efficacy.

OBJECTIVE: To characterize the microbiome associated with acute exacerbations of chronic rhinosinusitis (AECRS).

METHODS: We conducted a systematic review of …

Quadruple aberrant hyperphosphorylated tau (p-τ), amyloid-β peptide, alpha-synuclein and TDP-43 brainstem and supratentorial pathology are documented in forensic ≤40y autopsies in Metropolitan Mexico City (MMC), and p-τ is the major aberrant protein. Post-traumatic stress disorder (PTSD) is associated with an elevated risk of subsequent dementia, and rapid eye movement sleep behavior disorder (RBD) is documented in PD, AD, Lewy body dementia and ALS. This study aimed to identify an association between PTSD and potential pRBD in Mexico. An anonymous online survey of 4502 urban college-educated adults, 29.3 ± 10.3 years; MMC, n = 1865; non-MMC, n = 2637, measured PTSD …

Clinical Assessment Of Cognitive Function In Patients With Head And Neck Cancer: Prevalence And Correlates, Amy M. Williams, Jamie Lindholm, Farzan Siddiqui, Tamer Ghanem, Steven S. Chang

Otolaryngology Articles

Objective: Identify the prevalence and clinical correlates of cognitive impairment in patients presenting for treatment of head and neck cancer (HNC) using brief screening within a multidisciplinary care team.

Study Design: A case series with planned data collection of cognitive function, quality of life (QoL), and psychosocial variables.

Setting: Urban Midwest academic medical center.

Subjects and Methods: In total, 209 consecutive patients with a diagnosis of HNC between August 2015 and September 2016 who had a pretreatment assessment with a clinical health psychologist. At pretreatment assessment, the Montreal Cognitive Assessment (MoCA), a brief screening tool for cognitive function, was administered …

Free Flap Reconstruction Monitoring Techniques And Frequency In The Era Of Restricted Resident Work Hours, Urjeet A. Patel, David Hernandez, Yelizaveta Shnayder, Mark K. Wax, Matthew M.

Importance: Free flap reconstruction of the head and neck is routinely performed with success rates around 94% to 99% at most institutions. Despite experience and meticulous technique, there is a small but recognized risk of partial or total flap loss in the postoperative setting. Historically, most microvascular surgeons involve resident house staff in flap monitoring protocols, and programs relied heavily on in-house resident physicians to assure timely intervention for compromised flaps. In 2003, the Accreditation Council for Graduate Medical Education mandated the reduction in the hours a resident could work within a given week. At many institutions this new era …

Biological Significance Of Genome-Wide Dna Methylation Profiles In Keloids, Lamont R. Jones, Joshua B. Greene, Kang-Mei Chen, George Divine, Dhananjay A. Chitale, Veena Shah, Indrani Datta, Maria Worsham

Otolaryngology Articles

OBJECTIVES/HYPOTHESIS: To obtain biological insight into keloid pathogenesis and treatment using pathway analysis of genome-wide differentially methylated gene profiles between keloid and normal skin.

STUDY DESIGN: Prospective cohort.

METHODS: Genome-wide profiling was previously done, with institutional review board approval, on six fresh keloid and six fresh normal skin tissue samples, using the Infinium HumanMethylation450 BeadChip kit. Statistically significant differentially methylated cytosine-phosphodiester bond-guanines (CpGs, n = 197) between keloid and normal tissue mapped to 152 genes. These genes were uploaded into Ingenuity Pathway Analysis (IPA) software to identify biological functions or regulatory networks interacting. The pathways (or "network") with an enrichment …

Integrated Psychological Care In Head And Neck Cancer: Views From Health Care Providers, Patients, And Supports, Michelle T. Jesse, Michael Ryan, Anne Eshelman, Tamer Ghanem, Amy M. Williams, Lisa R. Miller-Matero, Kathleen Yaremchuk

Otolaryngology Articles

OBJECTIVES/HYPOTHESIS: An evaluation by head-and-neck cancer (HNC) staff, patients, and patient support feedback regarding integrated psychological care and perceived benefit based on patient characteristics.

STUDY DESIGN: Cross-sectional survey of HNC staff, patients, and their primary supports; and retrospective chart review of psychiatric characteristics of HNC patients.

METHODS: HNC staff, patients (who were evaluated by the integrated psychologist), and their primary supports were given questionnaires on their perception of benefit of including a psychologist in the evaluation and treatment of HNC patients. Also, a retrospective chart review on patients who were psychiatrically evaluated by the psychologist on sociodemographics and psychiatric characteristics. …

Cell Signaling Events Differentiate Er-Negative Subtypes From Er-Positive Breast Cancer, Maria Worsham, Dhananjay A. Chitale, Kang-Mei Chen, Indrani Datta, George Divine

Otolaryngology Articles

Currently available markers routinely used in clinical practice are of limited value to patients with estrogen receptor-negative (ER(-)) breast cancer [basal-like and HER2neu-positive (HER(+))], an aggressive subtype. Our aim was to uncover molecular pathways and signaling networks exposed by differentially methylated genes informative of the biology of ER(-) breast cancer (BC) subtypes versus ER-positive (ER(+)). Whole-genome methylation array analysis was carried out using the Illumina Infinium HumanMethylation27 BeadChip on 14 primary BC: five ER(+), four triple-negative (TNBC), and five ER(-)HER2(+). Degree of methylation was calculated as a β-value (ranging from 0 to 1), and M-values [log (β/(1 - β)] were …

Genome-Wide Scan For Methylation Profiles In Keloids, Lamont R. Jones, William Young, George W. Divine, Indrani Datta, Kang-Mei Chen, David M. Ozog, Maria Worsham

Otolaryngology Articles

Keloids are benign fibroproliferative tumors of the skin which commonly occur after injury mainly in darker skinned patients. Medical treatment is fraught with high recurrence rates mainly because of an incomplete understanding of the biological mechanisms that lead to keloids. The purpose of this project was to examine keloid pathogenesis from the epigenome perspective of DNA methylation. Genome-wide profiling used the Infinium HumanMethylation450 BeadChip to interrogate DNA from 6 fresh keloid and 6 normal skin samples from 12 anonymous donors. A 3-tiered approach was used to call out genes most differentially methylated between keloid and normal. When compared to normal, …
