INTRODUCTION AND OBJECTIVES: Laryngopharyngeal Reflux (LPR) is a disease characterized by the presence of symptoms, signs and tissue damage caused by retrograde flow of gastric contents to the upper aerodigestive tract. It represents up to 10% of otolaryngology consultations. The aim of the study is to describe the findings obtained by applying the salivary pepsin test (PEP-test) in a sample of patients with the clinical suspicion of LPR. MATERIAL AND METHODS: Our descriptive clinical study included 142 subjects with symptoms suggestive of LPR and a score above 13 on the RSI scale...

Objectives: This study evaluated whether the symptoms of laryngopharyngeal reflux (LPR) change after multilevel surgery for obstructive sleep apnea (OSA). Methods: Patients who underwent multilevel surgery for OSA between April 2009 and September 2014 were enrolled in this study. All patients underwent preoperative polysomnography prior to surgery and were asked to complete the reflux symptom index (RSI) questionnaire before and after surgery. Results: Of 73 enrolled patients, 24 (33%) reported an RSI score >13 and were thus classified as having reflux...

BACKGROUND: Respiratory instability in chronic heart failure (CHF) is characterized by irregularly rapid respiration or non-periodic breathing rather than by Cheyne-Stokes respiration. We developed a new quantitative measure of respiratory instability (RSI) and examined its independent prognostic impact upon CHF. METHODS: In 87 patients with stable CHF, respiratory flow and muscle sympathetic nerve activity (MSNA) were simultaneously recorded. RSI was calculated from the frequency distribution of respiratory spectral components and very low frequency components...

The reactive strength index (RSI) is often used to quantify drop jump (DJ) performance; however, not much is known about the biomechanical determinants of the RSI. The purpose of this study was to investigate the correlations between the RSI and several biomechanical variables calculated from DJ performed with different initial drop heights. Twelve, male NCAA DI basketball players performed DJ from drop heights of 30, 45, and 60 cm. Force plates were used to calculate DJ performance parameters (i.e., DJ height, contact time, and RSI) and DJ biomechanical variables (i...

BACKGROUND: Hypertrophy of the lingual tonsil tissue in the adult patient is thought to contribute to the pathophysiology of obstructive sleep apnea. The underlying etiology of lingual tonsil hypertrophy (LTH) in the adult patient is unclear and likely multifactorial. Previous studies have suggested that the lingual tonsils may undergo compensatory hyperplasia post-tonsillectomy in children, although it is unknown if this occurs or persists into adulthood. The purpose of this study was to determine what factors are associated with LTH in a population of Canadian adults...

OBJECTIVES: We sought to examine the physiological impact the apneic period has on the respiratory physiology of patients undergoing intubation in the emergency department and whether DAO, the delivery of 15L oxygen by nasal cannula during apnea, can affect the development of respiratory acidosis. METHODS: This was a prospective observational cohort study conducted at an urban academic level 1 trauma center. A convenience sample of 100 patients was taken. Timed data collection forms were completed during the periintubation period...

The aim of this paper is to extend the so-called semantic Stroop paradigm (Neely & Kahan, 2001) - which already successfully distinguishes between the contribution of the semantic vs. response conflict to Stroop interference - so that it can take account of and capture the separate contribution of task conflict. In line with this idea, the Stroop interference observed using the aforementioned paradigm with both short and long RSIs (500 vs. 2000ms) did indeed reflect the specific contribution of the task, semantic and response conflicts...

Background: Regional radiation therapy (RT) has been shown to reduce the risk of regional recurrence with node-positive cutaneous melanoma. However, risk factors for regional recurrence, especially in the era of sentinel lymph node biopsy (SLNB), are less clear. Our goals were to identify risk factors associated with regional recurrence and to determine whether a radiosensitivity index (RSI) gene expression signature (GES) could identify patients who experience a survival benefit with regional RT. Methods: A single-institution, Institutional Review Board-approved study was performed including 410 patients treated with either SLNB with or without completion lymph node dissection (LND; n=270) or therapeutic LND (n=91)...

SIGNIFICANCE: Oxidative stress is thought to account for aberrant redox homeostasis and contribute to aging and disease. However, more often than not administration of antioxidants is ineffective, suggesting our current understanding of the underlying regulatory processes is incomplete. Recent Advances. Similar to reactive oxygen and nitrogen species (ROS, RNS), reactive sulfur species (RSS) are now emerging as important signaling molecules, targeting regulatory cysteine redox switches in proteins, affecting gene regulation, ion transport, intermediary metabolism and mitochondrial function...

The purpose of this study was to identify the effectiveness of low and high volume plyometric loads on developing stretch shortening cycle capability in collegiate rugby players. A between- group repeated measures design was used. Thirty six subjects (age 20.3 ±1.6 yrs, mass 91.63 ±10.36kg, stature 182.03 ±5.24cm) were randomly assigned to one of three groups, a control group (CG), a low volume plyometric group (LPG) or a high volume plyometric group (HPG). Data were collected from a force plate, and measures of reactive strength index (RSI) and leg stiffness were calculated from jump height, contact time and flight time...

Flexible inorganic-organic silica aerogels based on methyltrimethoxysilane (MTMS, CH3Si(OCH3)3) can overcome the drawbacks of conventional silica aerogels by introducing high mechanical strength, elastic recovery and hydrophobicity to monolithic materials. In this work, MTMS is co-condensed with organofunctional alkoxysilanes RSi(OMe)3 (R = vinyl, chloropropyl, mercaptopropyl, methacryloxypropyl, etc.) yielding aerogels that are not only flexible but also contain reactive functional groups. Sol-gel parameters, such as the MTMS/RSi(OMe)3 ratio, have been systematically investigated in terms of gelation behavior, complete/incomplete incorporation of the functional organic groups (confirmed by FTIR-ATR and Raman spectroscopy) and flexibility of the resulting gel...

Implementation literature has under-reported bottom-up dissemination attempts of research-supported interventions (RSI). This study examined factors associated with individual clinicians' implementation of Child-Parent Psychotherapy (CPP), including CPP social network (SN), supervision, and self-efficacy. Seventy-seven (90%) CPP graduates completed a cross-sectional survey, including measures regarding social network, receiving supervision, and CPP self-efficacy. Self-efficacy was significantly associated with CPP implementation; CPP SN and supervision were not...

Classic gastroenterological diagnostic tools have proven to be insufficient in identifying the causal relationship between extra-esophageal symptoms and presumed pathological reflux activity. Some new methodological approaches, such as functional endoscopy (video panendoscopy, VPE), are considered to be helpful. However, there are currently no data objectively verifying the success of this method. In a previous study, we found a good correlation between the reflux symptom index (RSI) according to Belafsky and endoscopic findings...

This study examined the delayed effects of a power type training session on explosive performance. Seventeen well-trained male power and team sport athletes (age: 22.7±5.5 y, height: 181±8 cm, body mass: 80.7±8.6 kg, body fat: 9.2±1.7 %, 1-RM half-squat: 163±29 kg) performed four sessions (2 experimental and 2 control) one week apart in a randomized and counterbalanced order. Explosive performance was assessed before, 24 and 48 h following a low-volume, power-type training session (5 x 4 jump squats at 40% 1RM with 3 min rest), as well as before and after 24 and 48 h of rest (control)...

Due to the great advantages, it is not possible to imagine current practice in anesthesia without the adminstration of muscle relaxants. For a long time the administration of succinylcholine for rapid sequence induction (RSI) was considered to be the state of the art for patients at risk for aspiration. The favorable characteristics are, however, accompanied by many, sometimes severe side effects. Due to the development of non-depolarizing muscle relaxants, in particular rocuronium in combination with sugammadex, there is the possibility to achieve a profile of action similar to succinylcholine with low side effects...

Three studies examined the hypothesis that bilinguals can more rapidly disengage attention from irrelevant information than monolinguals by investigating the impact of previous trial congruency on performance in a simple flanker task. In Study 1, monolingual and bilingual young adults completed two versions of a flanker task. There were no differences between language groups on mean reaction time using standard analyses for congruent or incongruent trials or the size of the flanker effect. Sequential congruency effects (SCEs) however, which account for previous trial congruency, were smaller for bilinguals than for monolinguals...

To evaluate treatment response in patients with laryngopharyngeal reflux (LPR). A prospective study of 100 patients with voice disorders was conducted. Patients were evaluated using reflux symptom index (RSI) and reflux finding score (RFS) by 70° rigid laryngoscope. Patients with RFS score of 7 or more were diagnosed of having LPR and were started with anti-reflux therapy for a period of 6 months. Patients were assessed at regular intervals using RSI and RFS. The prevalence of LPR in patients with voice disorders was found to be 25%...

BACKGROUND: Retained surgical instruments (RSI) are one of the most serious preventable complications in operating room settings, potentially leading to profound adverse effects for patients, as well as costly legal and financial consequences for hospitals. Safety measures to eliminate RSIs have been widely adopted in the United States and abroad, but despite widespread efforts, medical errors with RSI have not been eliminated. OBJECTIVE: Through a systematic review of recent studies, we aimed to identify the impact of radio frequency identification (RFID) technology on reducing RSI errors and improving patient safety...
