Download or read book Occupational Voice written by Philippe H. Dejonckere and published by Kugler Publications. This book was released on 2001 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction The concept of occupational voice disorders Philippe H. Dejonckere "People using their voice professionally are at risk for occupational voice diseases, and require specific prevention and treatment" was the topic focused on by the third Pan European Voice Conference, organized in August 1999 at Utrecht University. The present book includes the main tutorial lectures, with reviews of the most relevant research data and opinions regarding this specific area of concern. Occupational voice users include not only singers and actors, but also teachers, politicians, lawyers, clergymen, telephone operators, etc.(1). The pathogenesis of voice disorders in such patients can be primarily related to their occupation, and thus, after adequate differential diagnosis, these need to be recognized as true occupational diseases, in the same way as, for example, occupational hearing loss (2). A surfeit of information is available on the potential damage from exposure to excessive noise levels(3,4). Noise-induced hearing loss is generally recognized as a typical occupational disease. The relationship between dose and effect is clear, as is documented in publications by the International Organization of Standardization (ISO) (5). The dose combines intensity and duration, and therefore, the concept of dosimetry is of major importance. Also of importance is the definition of the safe limits for exposure to noise. However, factors regarding individual susceptibility to noise and the reversibility of early effects also have to be considered, as well as possible preventive indices of noise-induced hearing loss (6). In some - but not all - respects, noise-induced hearing loss may be considered as a useful model for occupational voice disorders. Epidemiology Titze (7) compared the percentage of the US working population and of the voice-clinic load for different occupation categories: for example, telephone marketers constitute only 0.78% of the total workforce, but 2.3% of the clinic load; teachers represent 4.2% of the US workforce and 20% of the voice-clinic load. Studies based on questionnaires have suggested that teachers and aerobic instructors are at high risk for disabilities from voice disorders, and that these health problems may have significant work-related and economic effects (8,9). For example, Russel et al.(10) investigated the prevalence of self-reported voice problems in teachers: 16% of teachers reported voice problems on the day of the survey, 20% during the current teaching year, and 19% at some time during their career. Roughly speaking, we can conclude from the several studies published during the 1990s that about 20% of teachers experience voice disorders (11). Voice dosimetry Objective measurement of vocal use and vocal load is necessary for the identification of activities and working conditions that are at risk. Voice dosimeters can provide information on the total vocalization time and sound pressure level over a whole working day, in a real life situation (12-14). Just as noise dosimeters define acceptable levels of noise exposure, voice dosimeters help to define the average acceptable limits for vocal load. Hyperphonation Repeated mechanical vibrations transmitted to the body tissues by engines or machines are known to be able of eliciting - in certain conditions - specific kinds of pathology, which are also considered to be occupational diseases (15,16). The vibration may involve the whole body (e.g., in a vehicle) or mainly the hand, wrist, elbow, or shoulder (hand-held power tools). There are standards in the field of occupational health that stipulate the acceptable limits for tissue acceleration values, depending on the frequency (17). Titze's calculations suggest that the risk of damage from tissue vibration is exceeded by occupational vocalists, such as telephone marketers and teachers (18). In the last few years, much new and important information has materialized on the dangers of 'hyperphonation', i.e., loud and prolonged phonation beyond the physiological range. Laboratory experiments on canine larynges, hyper-phonated in vivo under anesthesia, demonstrated obvious damage to vocal fold epithelia (19). The basement membrane shows early lesions and seems to be particularly sensitive (20). A clinical study by Mann et al.(21) in drill sergeants, demonstrated significant increases in vocal fold edema, erythema and edge irregularity, and decreases in vocal fold mucosal wave and amplitude of excursion, following a five-day training period Voice fatigue, relief and recovery According to Titze (18) , two different aspects must be considered: Muscle fatigue: the muscle chemistry needs to be reset for the following contractions. Epithelial cells may die and be shed, due to repeated traumata. New cells have to develop underneath. Collagen and elastin fibers may have separated from the structural matrix of the lamina propria, and have to be removed and replaced by the fibroblasts. Detached protein debris will be removed and re-used by the fibroblasts to make new protein fibers that will support the connective tissue structure. Therefore, minor destruction and repair is continuous. Can the regenerative processes keep up with the destructive process, and what are the physiological time constants in these processes? When there is damage to the joints, ligaments, tendons, or other connective tissue, the recovery time will be proportional to the amount of localized tissue injury that has occurred. If muscle fatigue is the only complaint, the recovery period required will probably be shorter. Hypothetical curves for tissue injury and the recovery period for human phonation have been suggested by Titze (18). Nevertheless, vocal fatigue is still difficult to identify in practical and clinical situations, and Buekers has questioned the clinical relevance of voice endurance tests (13,14). Environmental factors The relative humidity of the air affects vocal function: the most common subjective complaints of teachers with regard to their working environment are the dryness and dustiness of the air. Professional singers note that singing is more difficult in a dry environment: dry air puts an increased strain on the phonatory apparatus and raises the demands on its efficacious and appropriate use (22). The human voice is very sensitive to decreases in the relative humidity of inhaled air because, in experimental conditions, even after short provocation, a significant increase in perturbation measures has been found (23). Noise is also a very common and relatively well-known risk factor in the working environment of professional voice users. It has been observed that the sound level of the speaking voice significantly increases in ambient noise levels starting from 40 dB (A) (about 3 dB for each 10 dB increase in ambient noise), due to the Lombard effect (24,25). In kindergartens, for example, noise levels have been found to vary between 75 and 80 dB (A) (26,27). Effects of stress Mendoza and Carballo investigated the effects of experimentally induced stress on voice characteristics (28). In conditions of stress, induced by means of a stressful environment and cognitive workload tasks, they observed: 1. an increase in F o with respect to baseline; 2. a decrease in pitch perturbation quotient and in amplitude perturbation quotient; 3. a lower presence of turbulent noise in the spectral zone in which the existence of harmonic components is not expected (2800-5800 Hz), with respect to harmonic energy in the 70-4500 Hz range; 4. an increase in harmonic energy in the 1600-4500 Hz range with respect to harmonic energy in the 70-1600 Hz range. The increase in F o seems to be considered a universal indicator of stress and of cognitive workload, as is the lowering of F o perturbation. The response to a stressful stimulus demands a high level of activation, which in turn produces elevated ergotropic arousal that would cause an increase in the tension of the vocal muscles, producing a higher and more tense voice. Mattiske et al. (29) report that teachers seem to experience a significant degree of stress during their work (30) , and there is some research evidence that anxiety and stress are associated with the development of voice problems (31). Marks (32) compares teachers' voices with those of nurses, and finds that psychological stress is reported more frequently by teachers. There are indications that stress, psychological tension, personality, and other psychological factors, may play an important role in voicing problems among teachers (30,33,34). Vocal fold lesions Phonotrauma may result in typical vocal fold lesions, to be interpreted as a direct consequence of mechanical stress and/or as tissue reaction to that stress. Vocal fold nodules and polyps are classical examples (35,36) , but also contact ulcerations/ granulomas of the vocal processes (35,36,37) , if not induced by acid re-flux. Vocal fold hemorrhage is generally consecutive to acute phonotrauma (35). Depending on reversibility and context, microsurgery may become indicated as an important element of the treatment (38,39). Care and cure Patients with occupational voice disorders should benefit from specific medical and paramedical treatments, as well as from technical aids, with respect to their particular pathogenesis. There are major economical aspects at stake, and occupational rehabilitation plays an important role. In a few cases, compensation and professional re-orientation is necessary. Outcomes of the various possible treatment strategies have still to be investigated. However, prevention is still essential. There are indications that vocal hygiene education programs could improve the voice by reducing vocal abuse in daily life and by practising specific strategies to maintain classroom order and to reduce the use of the voice during teaching (40). Further research is needed to demonstrate the usefulness of prevention strategies on the incidence of actual voice disorders.

Download or read book Obesity and Diabetes written by Joel Faintuch and published by Springer Nature. This book was released on 2020-12-14 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in its second edition, this comprehensive handbook provides a state-of-the-art overview of recent advances in drug and non-drug therapies for obesity and diabetes. It also addresses major comorbidities, covering topics such as, cardiovascular diseases, renal and neuropsychiatric disorders, appetite control and micro RNAs. Special attention is also devoted to pediatric care, including the latest recommendations for therapy and prevention. Obesity and type 2 diabetes are among the top global health-care budget concerns worldwide and impact professional practice at all levels: in hospitals, clinics and physicians’ offices alike. They prominently feature in headlines, and virtually no family, community or country is exempt from their protean, deleterious consequences. Furthermore, given the multiple intersections in their pathways, they often go hand in hand. The good news is that scientific advances in all fields, including genomics, metabolomics, lipidomics and microbiomics, are increasing our understanding of these two disease areas. At the same time, artificial intelligence, machine learning, mobile health and advanced implantable and external devices are rendering prevention and management more available, safe and cost-effective. In addition, bariatric and metabolic surgery has evolved from a niche specialty to an officially endorsed option for several modalities of obesity and diabetes. This book presents the latest lifestyle, pharmacological, surgical and non-surgical treatment options, including endoscopic intervention and cell therapy. Objectively reviewing natural and artificial sweeteners and critically examining issues such as public health initiatives, government mandated taxes for unhealthy foods and environmental planning, no stone is left unturned in gathering the latest practical information. As such, the book will appeal to seasoned specialists, as well as students and healthcare professionals in training.

Download or read book Zika written by Debora Diniz and published by Zed Books Ltd.. This book was released on 2017-09-15 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2017 Jabuti Book Prize The Zika virus is devastating lives and communities. Children across the Americas are being born with severe disabilities because of it. Yet during the desolating outbreak, Brazil played host to both the Olympics and the FIFA World Cup, leading many to suspect that the true impact of the virus has been subject to a cover-up of international proportions. Beginning in the northeast, where the devastation has been most felt, professor of bioethics and award-winning documentary filmmaker Debora Diniz travels across Brazil tracing the virus’s origin and spread. Along the journey she meets a host of fearless families, doctors and scientists uncovering the virus’s impact on local communities. In doing so Diniz paints a vivid picture of the Zika epidemic, exposing the Brazilian government’s complicity in allowing the virus to spread while championing the efforts of local doctors and mothers who, working together, are raising awareness of the virus and fighting for the rights of children affected by Zika.

Download or read book Inequality in Brazil A Regional Perspective written by Carlos Góes and published by International Monetary Fund. This book was released on 2017-10-31 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, we document the decline in income inequality and a convergence in consumption patterns in Brazilian states in a new database constructed from micro data from the national households’ survey. We adjust the state-Gini coefficients for spatial price differences using information on households’ rental prices available in the survey. In a panel regression framework, we find that labor income growth, formalization, and schooling contributed to the decline in inequality during 2004-14, but redistributive policies, such as Bolsa Família, have also played a positive role. Going forward, it will be important to phase out untargeted subsidies, such as public spending on tertiary education, and contain growth of public sector wages, to improve budgetary efficiency and protect gains in equality.

Download or read book Leveraging Data Science for Global Health written by Leo Anthony Celi and published by Springer Nature. This book was released on 2020-07-31 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book explores ways to leverage information technology and machine learning to combat disease and promote health, especially in resource-constrained settings. It focuses on digital disease surveillance through the application of machine learning to non-traditional data sources. Developing countries are uniquely prone to large-scale emerging infectious disease outbreaks due to disruption of ecosystems, civil unrest, and poor healthcare infrastructure – and without comprehensive surveillance, delays in outbreak identification, resource deployment, and case management can be catastrophic. In combination with context-informed analytics, students will learn how non-traditional digital disease data sources – including news media, social media, Google Trends, and Google Street View – can fill critical knowledge gaps and help inform on-the-ground decision-making when formal surveillance systems are insufficient.

Download or read book Conditional Cash Transfers written by Ariel Fiszbein and published by World Bank Publications. This book was released on 2009-02-09 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conditional Cash Transfer (CCT) programs aim to reduce poverty by making welfare programs conditional upon the receivers' actions. That is, the government only transfers the money to persons who meet certain criteria. These criteria may include enrolling children into public schools, getting regular check-ups at the doctor's office, receiving vaccinations, or the like. They have been hailed as a way of reducing inequality and helping households break out of a vicious cycle whereby poverty is transmitted from one generation to another. Do these and other claims make sense? Are they supported by the available empirical evidence? This volume seeks to answer these and other related questions. Specifically, it lays out a conceptual framework for thinking about the economic rationale for CCTs; it reviews the very rich evidence that has accumulated on CCTs; it discusses how the conceptual framework and the evidence on impacts should inform the design of CCT programs in practice; and it discusses how CCTs fit in the context of broader social policies. The authors show that there is considerable evidence that CCTs have improved the lives of poor people and argue that conditional cash transfers have been an effective way of redistributing income to the poor. They also recognize that even the best-designed and managed CCT cannot fulfill all of the needs of a comprehensive social protection system. They therefore need to be complemented with other interventions, such as workfare or employment programs, and social pensions.

Download or read book Disease Control Priorities Third Edition Volume 2 written by Robert Black and published by World Bank Publications. This book was released on 2016-04-11 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evaluation of reproductive, maternal, newborn, and child health (RMNCH) by the Disease Control Priorities, Third Edition (DCP3) focuses on maternal conditions, childhood illness, and malnutrition. Specifically, the chapters address acute illness and undernutrition in children, principally under age 5. It also covers maternal mortality, morbidity, stillbirth, and influences to pregnancy and pre-pregnancy. Volume 3 focuses on developments since the publication of DCP2 and will also include the transition to older childhood, in particular, the overlap and commonality with the child development volume. The DCP3 evaluation of these conditions produced three key findings: 1. There is significant difficulty in measuring the burden of key conditions such as unintended pregnancy, unsafe abortion, nonsexually transmitted infections, infertility, and violence against women. 2. Investments in the continuum of care can have significant returns for improved and equitable access, health, poverty, and health systems. 3. There is a large difference in how RMNCH conditions affect different income groups; investments in RMNCH can lessen the disparity in terms of both health and financial risk.
