Salivary cortisol is used as a diagnostic analysis in the investigation of suspected Cushings' syndrome. This study evaluates if liqourice intake increases salivary cortisol in healthy individuals. Late night salivary cortisol and cortisone is analysed before, during and after 7 days of liqourice intake in three different doses.
The effect of noise is often underestimated but it is one of the most common occupational health hazards. Its health effects include; noise-induced hearing loss, sleep disturbance, interference with speech comprehension, complaints, stress, annoyance, and safety concerns with regard to workers being able to complete their tasks in a safe manner. This pilot aims to measure and analyze noise levels in obstetric ORs at BC Women's Hospital during elective and emergency cesarean de...
Aldosterone, the major mineralocorticoid hormone and cortisol, the major glucocorticoid hormone are produced in the adrenal gland. Aldosterone binds intracellular mineralocorticoid receptors (MR) in the kidney promoting urinary reabsorption of sodium and water and excretion of potassium and hydrogen ions. Unregulated mineralocorticoid excess may, therefore, lead to high blood pressure due to sodium and water retention and hypokalaemic alkalosis. Blood concentrations of c...
This study investigates the salivary LL-37 in passive smoking-exposed and unexposed children and the association between salivary LL-37 levels and periodontal clinical parameters in these children.Unstimulated salivary samples were collected from 180 children (90 passive smoking-exposed and 90 passive smoking-unexposed)
RATIONALE: Exposure to formaldehyde in the work place may affect the risk of developing cancer later in life. Learning about the long-term effects of formaldehyde exposure may help the study of cancer in the future. PURPOSE: This clinical trial is studying precancerous myeloid cells in workers exposed or not exposed to formaldehyde.
Trigger finger, also known as stenosing tenosynovitis, is a painful condition that can cause discomfort and disability. Many physicians choose to locally inject cortisone into the infected finger although there is no current consensus as to how many injections are needed to achieve maximum relief. This study will be a prospective, randomized study to compare one versus two injections for the treatment of trigger finger.
The aim of this study was to investigate the influence of the use of headphones in salivary cortisol levels in newborns (NB) during periods of nap aimed at noise reduction, brightness and handling NB, measure the concentrations of salivary cortisol before (baseline) and after the use of hearing protection (response) in the neonatal intensive care unit (NICU). A NICU nap periods and compare the influence of the use and non-use of hearing protection in salivary cortisol levels a...
The purpose of this study is to investigate the health effects of benzene exposure in workers in Shanghai, China.
The study is a single blinded randomized control trial. Participants were blinded to the purpose of the study and to the level of noise they would be exposed. Anesthesiology residents and certified anesthesiologists were recruited.The goal of this study was to measure the time needed to initiate treatment(TNIT) of a severe bradycardia while performing a spinal anesthesia in a high-fidelity simulation environment with either a low or a high ambient dB-level.
The aim of the study is to examine possible changes in lung function, nitric oxide levels and systemic inflammatory markers in cement dust exposed workers, during one shift (6-8 hours).
Many patients complain to clinicians that they have difficulty sleeping appears to be due to environmental noise. There is a common perception that acute noises are more troublesome than continuous noises in the effect on individual sleep quality. Therefore the goal is to use a Marpac white noise maker with a continuous noise to see its effect on individuals that have difficulty sleeping in a high noise environment.
Although salivary contents play a major role in the early stage of food digestion process, their role in taste perception of glucose polymers is essentially unknown. It is hypothesized that the differences in salivary contents, more specifically salivary amylase concentration and activity, influence taste perception of glucose polymers and ultimately eating behavior, which is related to risks in various diseases. The current project is designed to investigate 2 aims. Aim 1 will...
The primary objective of this work is to determine the effect noise has on the auditory system (both auditory health and performance) and also the degree to which the effect of pre-noise therapy such as NIR light can mitigate the effects of noise exposure. The ability of NIR light therapy to protect against the effects of noise will be determined by measuring the health of the auditory system using hearing threshold measurements and monitoring the stability of audiometric data ...
Hearing loss is the most prevalent service-connected disability in the VA. It causes communication difficulties, which contribute to isolation, frustration and depression. A major cause of hearing loss is from exposure to high levels of sound, and is referred to as Noise Induced Hearing Loss (NIHL). Veterans have inevitably been exposed to high levels of sound during military service, and even though they may not yet have NIHL, their ears have been damaged. Continued noise expo...
Saturnism, or lead poisoning, is defined by clinical symptoms (affecting primarily the nervous, hematopoietic, gastrointestinal, cardiovascular, musculoskeletal, renal and reproductive systems) compatible with exposure, in the short or long term, to lead or to its compounds, and can manifest as acute or chronic symptoms, pursuant to the intensity and duration of the signs and symptoms. Measuring serum concentration is the primary method for diagnosing and accompanying exposed w...
The objective of this project is to determine if giving a cortisone injection to patients with proximal humerus fractures who have stiff shoulders recover their range of motion.
This study will examine the risks of workplace exposure to benzene, a substance known to lead to cancer of the blood and possibly of the lungs. It is used widely in industries and is a contaminant in the environment. Researchers from the National Cancer Institute and the China Center for Disease Control (formerly Chinese Academy of Preventive Medicine) had done previous studies of workers in manufacturing industries in China-of people who worked at least 1 day from 1972 to 1987...
Construction workers have the highest rate of smoking among all occupations, and are frequently exposed to a wide range of workplace hazards (e.g. toxins), which interact with smoking to increase their health risks. Minority construction workers, in particular, have higher smoking and lower cessation rates compared to other groups, and they generally show lower access and participation in cessation and health promotion services. The number of Hispanic workers employed in the co...
This project will investigate whether reduction in ambient light and elimination of noise during induction and emergence from anesthesia influences the response time of the anesthesia provider to auditory and visual alarms when compared to a standard operating room. In addition, the investigators will assess the cumulative level of noise exposure that providers experience during the perioperative period.
The patients were randomly separated into three groups. Group M (n=35) applied CD player and Group S (n=35) received the independent anesthesiologist placed earplugs into the patients' ears. Group N (n=35) exposed to the ambient operating room noise.
