Extended partial laryngectomy with functional preservation using the rotational crico-thyrotracheopexy.

Objectives: Glottic tumors with infiltration of the anterior/posterior commissure, and lesions with subglottic, cricoid, or cricoarytenoid joint infiltration have been highly controversial in the past, from the perspective of oncological safety. Although conservation laryngeal resection options exist, most are limited by the extent of resection proscribed by the technique and the postoperative functional results. Oncologically speaking, extended vertical hemilaryngectomy is often the optimal solution.

Relationship of arterial stiffness and baseline vascular burden with new lacunes and microbleeds: A longitudinal cohort study.

Introduction: Arterial stiffness may have a significant impact on the development of cerebral small vessel disease (cSVD).

Patients And Methods: We obtained pulse wave velocity (24-h PWV) by means of ambulatory blood pressure monitoring (ABPM) in patients with a recent small subcortical infarct (RSSI). Patients with known cardiac or arterial embolic sources were excluded.

Cognitive Radio with Machine Learning to Increase Spectral Efficiency in Indoor Applications on the 2.5 GHz Band.

Due to the propagation characteristics in the 2.5 GHz band, the signal is significantly degraded by building entry loss (BEL), making coverage in indoor environments in some cases non-existent. Signal degradation inside buildings is a challenge for planning engineers, but it can be seen as a spectrum usage opportunity for a cognitive radio communication system.

Comparative Treatment Outcomes for Idiopathic Subglottic Stenosis: 5-Year Update.

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol.

Endoscopic management of adult subglottic stenosis: an alternative to open surgery.

Purpose: Various surgical techniques could be used to treat subglottic stenosis (SGS). The aim of this study is to present our experience in endoscopic management of SGS and show the impact of symptoms' evaluation, clinical examination and spirometry in the therapeutic decision.

Increased mortality associated with uncontrolled diabetes mellitus in patients with pulmonary cryptococcosis: a single US cohort study.

Background: Diabetes mellitus is an established risk factor for bacterial infections, but its role in cryptococcosis is unclear. The study aimed to determine whether uncontrolled diabetes (HbA1c >7%) was an independent risk factor for mortality in cryptococcosis.

Methods: A retrospective case-control study partially matched by age and gender was performed in patients tested for infection at the University of Colorado Hospital from 2000 to 2019.

Association of Social Determinants of Health with Time to Diagnosis and Treatment Outcomes in Idiopathic Subglottic Stenosis.

Objectives: To examine whether social determinants of health (SDH) factors are associated with time to diagnosis, treatment selection, and time to recurrent surgical intervention in idiopathic subglottic stenosis (iSGS) patients.

Methods: Adult patients with diagnosed iSGS were recruited prospectively (2015-2017) via clinical providers as part of the North American Airway Collaborative (NoAAC) and via an online iSGS support community on Facebook. Patient-specific SDH factors included highest educational attainment (self-reported), median household income (matched from home zip code via U.

Impact of Obesity on Quality of Life, Psychological Distress, and Coping on Patients with Colon Cancer.

Background: Despite the causal relationship between obesity and colon cancer being firmly established, the effect of obesity on the course of cancer calls for further elucidation. The objective of this study was to assess differences in clinical-pathological and psychosocial variables between obese and nonobese individuals with colon cancer.

Materials And Methods: This was a prospective, multicentric, observational study conducted from 2015-2018.

Transoral closure of the supraglottic larynx for intractable aspiration.

The aim of this paper is to describe a novel, safe, and effective surgical technique to eliminate aspiration, that is performed entirely by reconstructive transoral laser microsurgery (R-TLM). Eleven tracheostomy-dependent patients with recurrent pneumonia secondary to intractable aspiration treated with transoral laryngeal closure were included in our study. In all cases, the supraglottic mucosa is incised in a circumferential manner.

Friend Support and the Parenting of Latina Adolescent Mothers: The Moderating Role of Maternal Age.

Objectives: This study examined the role of maternal age in the relation between social support from friends and parenting adjustment in a sample of young Latina mothers and their 18-month-old children (=168).

Methods: Hierarchical multiple regression analyses tested friend social support types (emotional, socializing, child care) as differential predictors of maternal behavior (sensitivity, cognitive growth-fostering, detachment) displayed during mother-child play interactions. To consider maternal development, the moderating role of maternal age on these associations was tested.

Structural investigation of doubly-dehydrogenated pyrene cations.

The vibrationally resolved spectra of the pyrene cation and doubly-dehydrogenated pyrene cation (CH˙; Py and CH˙; ddPy) are presented. Infrared predissociation spectroscopy is employed to measure the vibrational spectrum of both species using a cryogenically cooled 22-pole ion trap. The spectrum of Py allows a detailed comparison with harmonic and anharmonic density functional theory (DFT) calculated normal mode frequencies.
