Absorbed doses above1-2 Gy (100-200 rads) received over a period of a day or less lead to one or another of the acute radiation syndromes. These are the hematopoietic syndrome, the gastrointestinal (GI) syndrome, the cerebrovascular (CV) syndrome, the pulmonary syndrome, or the cutaneous syndrome. The dose that will kill about 50% of the exposed people within 60 days with minimal medical care, LD50-60, is around 4.5 Gy (450 rads) of low-LET radiation measured free in air. The GI syndrome may not be fatal with supportive medical care and growth factors below about 10 Gy (1000 rads), but above this is likely to be fatal. Pulmonary and cutaneous syndromes may or may not be fatal, depending on many factors. The CV syndrome is invariably fatal. Lower acute doses, or protracted doses delivered over days or weeks, may lead to many other health outcomes than death. These include loss of pregnancy, cataract, impaired fertility or temporary or permanent sterility, hair loss, skin ulceration, local tissue necrosis, developmental abnormalities including mental and growth retardation in persons irradiated as children or fetuses, radiation dermatitis, and other symptoms listed in Table 2 on page 12. Children of parents irradiated prior to conception may experience heritable ill-health, that is, genetic changes from their parents. These effects are less strongly expressed than previously thought. Populations irradiated to high doses at high dose rates have increased risk of cancer incidence and mortality, taken as about 10-20% incidence and perhaps 5-10% mortality per sievert of effective dose of any radiation or per gray of whole-body absorbed dose low-LET radiation. Cancer risks for non-uniform irradiation will be less.

Full Text Available Whole-body vibration (WBV exercise is an alternative, popular and easy exercise that can be followed by general public. Therefore, the aim of the present study was to investigate the influence of acute and chronic WBV exercise on health-related parameters. Twenty-eight women were allocated into a control group (n=11, mean ±SEM: age, 43.5 ±1.5 yr; body mass, 66.1 ±3.1 kg; height, 160.6 ±1.5 cm and a vibration group (n=17, mean ±SEM: age, 44.0 ±1.0 yr; body mass, 67.1 ±2.2 kg; height, 162.5 ±1.5 cm. After baseline assessments, participants of the experimental group performed WBV training 3 times/week for 8 weeks. Before and after the chronic WBV exercise, the participants of the vibration group performed one session of acute WBV exercise. Blood chemistry measurements (hematology, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, C-reactive protein, glucose, insulin, triacylglycerols, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apolipoprotein A1, apolipoprotein B and lipoprotein, thiobarbituric-acid reactive substances, protein carbonyls, total antioxidant capacity, uric acid, albumin and bilirubin were assessed pre-exercise and post-exercise at the first and eighth week of WBV exercise in both control and vibration groups. The results failed to support any effect of both acute and chronic WBV exercise on biochemical health-related parameters. However, it seems that WBV exercise is a safe way of training without a negative impact on muscle and liver functionality.

Acute inpatient mental health units are busy and sometimes chaotic settings, with high bed occupancy rates. These settings include acutely unwell patients, busy staff, and a milieu characterised by unpredictable interactions and events. This paper is a report of a literature review conducted to identify, analyse, and synthesize ethnographic research in adult acute inpatient mental health units. Several electronic databases were searched using relevant keywords to identify studies published from 1990-present. Additional searches were conducted using reference lists. Ethnographic studies published in English were included if they investigated acute inpatient care in adult settings. Papers were excluded if the unit under study was not exclusively for patients in the acute phase of their mental illness, or where the original study was not fully ethnographic. Ten research studies meeting our criteria were found (21 papers). Findings were grouped into the following overarching categories: (1) Micro-skills; (2) Collectivity; (3) Pragmatism; and (4) Reframing of nursing activities. The results of this ethnographic review reveal the complexity, patient-orientation, and productivity of some nursing interventions that may not have been observed or understood without the use of this research method. Additional quality research should focus on redefining clinical priorities and philosophies to ensure everyday care is aligned constructively with the expectations of stakeholders and is consistent with policy and the realities of the organisational setting. We have more to learn from each other with regard to the effective nursing care of inpatients who are acutely disturbed.

Radiation exposure from Solar Particle Events (SPE) presents a significant health concern for astronauts for exploration missions outside the protection of the Earth's magnetic field, which could impair their performance and result in the possibility of failure of the mission. Assessing the potential for early radiation effects under such adverse conditions is of prime importance. Here we apply a biologically based mathematical model that describes the dose- and time-dependent early human responses that constitute the prodromal syndromes to consider acute risks from SPEs. We examine the possible early effects on crews from exposure to some historically large solar events on lunar and/or Mars missions. The doses and dose rates of specific organs were calculated using the Baryon radiation transport (BRYNTRN) code and a computerized anatomical man model, while the hazard of the early radiation effects and performance reduction were calculated using the Radiation-Induced Performance Decrement (RIPD) code. Based on model assumptions we show that exposure to these historical events would cause moderate early health effects to crew members inside a typical spacecraft or during extra-vehicular activities, if effective shielding and medical countermeasure tactics were not provided. We also calculate possible even worse cases (double intensity, multiple occurrences in a short period of time, etc.) to estimate the severity, onset and duration of various types of early illness. Uncertainties in the calculation due to limited data on relative biological effectiveness and dose-rate modifying factors for protons and secondary radiation, and the identification of sensitive sites in critical organs are discussed.

On December 7, 2007, the Hebei Spirit oil tanker spilled out 12,547 kl of crude oil on the Yellow Sea 10 km away from the cost of Taean Province, Korea. As the coastline has been contaminated, local residents have been exposed to crude oil. Because the residents were showing many symptoms, we investigated the acute health effects of this oil spill on them. We conducted a cross-sectional study consisting of the heavy and moderately oil soaked area in Taean and the lightly oil soaked area in Seocheon. Ten seashore villages were selected from each area, and 10 male and female adults were selected from each village. We interviewed the subjects using a structured questionnaire on the characteristics of residents, the cleanup activities, the perception of oil hazard, depression and anxiety, and the physical symptoms. The odds ratios and 95% confidence intervals were analyzed using logistic regression analysis. The logistic regression model was adjusted for age, gender, education, smoking, the perception of oil hazard and anxiousness. The more highly contaminated the area, the more likely it was for residents to be engaged in cleanup activities and have a greater chance of exposure to oil. The indexes of anxiety and depression were higher in the heavy and moderately oil soaked areas. The increased risks of headache, nausea, dizziness, fatigue, tingling of limb, hot flushing, sore throat, cough, runny nose, shortness of breath, itchy skin, rash, and sore eyes were significant. The results suggest that exposure to crude oil is associated with various acute physical symptoms. Long-term investigation is required to monitor the residents' health.

facilitators in the development and implementation of teamwork education in acute hospital settings. Although the quality of the specific teamwork education programs was an important factor, there were a number of issues that also impacted on the experiences of health professionals who participated in teamwork education programs. These included the context that the program was delivered in, the diversity of health care teams, starting points of individual learners, the type of tools utilized in education programs, the levels of confidence and motivation of learners post training and the opportunity to transfer into practice new learning. Drawing from the synthesized findings of the review, recommendations for practice have been devised in order to guide the development and implementation of teamwork education in acute hospital settings and to improve the experience of participating health professionals. The Joanna Briggs Institute utilizes Grades of Recommendation to rate a health management strategy in terms of its desirable effects, evidence of adequate quality supporting its use, benefits of use, and the inclusion of patient experience, values and preferences. A strong recommendation has a Grade A and a weak recommendation has a Grade B. The FAME (Feasibility, Appropriateness, Meaningfulness and Effectiveness) scale was used to inform the strength of the following six recommendations for practice from the review: RECOMMENDATION ONE: All members of a team should be encouraged by their organization/managers to participate in teamwork education programs in order to foster a positive culture of learning and teamwork within the team.JBI Recommendation: Grade A. This recommendation is appropriate and applicable to all health professionals in acute hospital settings, is associated with positive experiences for participants of teamwork education programs and has a beneficial effect on participants. Facilitators of teamwork education programs should understand how successful teams

To determine whether multimedia based health information presented to parents of children with breathing difficulties in a pediatric acute ward, is more effective than verbal information, to reduce parental anxiety and increase satisfaction. This randomized controlled trial was conducted in a pediatric acute ward in Norway, from January to March 2011. Parents were randomly assigned to a multimedia intervention (n=53), or verbal health information (n=48). Primary outcome measure was parental anxiety, and secondary outcome measures were parental satisfaction with nursing care and health information. Parental anxiety decreased from arrival to discharge within both groups. At discharge the anxiety levels in the intervention group were no lower than in the control group. There was no difference in satisfaction with nursing care between the groups, but parents in the intervention group reported higher satisfaction with the health information given in the acute ward (p=.005). Multimedia based health information did not reduce anxiety more than verbal information, among parents to children with breathing difficulties. However, after discharge the parents were more satisfied with the multimedia approach. More research is needed to recommend the use of multimedia based information as a routine to parents in pediatric emergency care. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To test how the implementation of new Medicare post-acute payment systems affected the use of inpatient rehabilitation facilities (IRFs), skilled nursing facilities (SNFs), and home health agencies. Medicare acute hospital, IRF, and SNF claims; provider of services file; enrollment file; and Area Resource File data. We used multinomial logit models to measure realized access to post-acute care and to predict how access to alternative sites of care changed in response to prospective payment systems. A file was constructed linking data for elderly Medicare patients discharged from acute care facilities between 1996 and 2003 with a diagnosis of hip fracture, stroke, or lower extremity joint replacement. Although the effects of the payment systems on the use of post-acute care varied, most reduced the use of the site of care they directly affected and boosted the use of alternative sites of care. Payment system changes do not appear to have differentially affected the severely ill. Payment system incentives play a significant role in determining where Medicare beneficiaries receive their post-acute care. Changing these incentives results in shifting of patients between post-acute sites.

Hazardous chemicals escape to the environment by a number of natural and/or anthropogenic activities and may cause adverse effects on human health and the environment. Increased combustion of fossil fuels in the last century is responsible for the progressive change in the atmospheric composition. Air pollutants, such as carbon monoxide (CO), sulfur dioxide (SO 2 ), nitrogen oxides (NOx), volatile organic compounds (VOCs), ozone (O 3 ), heavy metals, and respirable particulate matter (PM2.5 and PM10), differ in their chemical composition, reaction properties, emission, time of disintegration and ability to diffuse in long or short distances. Air pollution has both acute and chronic effects on human health, affecting a number of different systems and organs. It ranges from minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults, aggravating pre-existing heart and lung disease, or asthmatic attacks. In addition, short- and long-term exposures have also been linked with premature mortality and reduced life expectancy. These effects of air pollutants on human health and their mechanism of action are briefly discussed. - The effect of air pollutants on human health and underlying mechanisms of cellular action are discussed

To investigate whether residents in the vicinity of the Sea Empress tanker spill suffered an increase in self reported physical and psychological symptoms, which might be attributable to exposure to crude oil. Retrospective cohort study; postal questionnaire including demographic details, a symptom checklist, beliefs about health effects of oil and the Hospital Anxiety and Depression and SF-36 mental health scales. Populations living in four coastal towns on the exposed south Pembrokeshire coast and two control towns on the unexposed north coast. 539 exposed and 550 unexposed people sampled at random from the family health services authority age-sex register who completed questionnaires. Adjusted odds ratios for self reported physical symptoms; scores on the Hospital Anxiety and Depression and SF-36 mental health scales, in 1089 people who responded out of a possible 1585 (69%). Living in areas exposed to the crude oil spillage was significantly associated with higher anxiety and depression scores, worse mental health; and self reported headache (odds ratio = 2.35, 95% CI 1.56, 3.55), sore eyes (odds ratio = 1.96, 95% CI 1.06, 3.62), and sore throat (odds ratio = 1.70, 95% CI 1.12, 2.60) after adjusting for age, sex, smoking status, anxiety, and the belief that oil had affected health. People living in exposed areas reported higher rates of physical and psychological symptoms than control areas. Symptoms significantly associated with exposure after adjustment for anxiety and health beliefs were those expected from the known toxicological effect of oil, suggesting a direct health effect on the exposed population.

Epidemiological findings concerning the seasonal variation in the acute effect of particulate matter (PM) are inconsistent. We investigated the seasonality in the association between PM with an aerodynamic diameter of less than 10 μm (PM10) and daily mortality in 17 Chinese cities. We fitted the “main” time-series model after adjustment for time-varying confounders using smooth functions with natural splines. We established a “seasonal” model to obtain the season-specific effect estimates of PM10, and a “harmonic” model to show the seasonal pattern that allows PM10 effects to vary smoothly with the day in a year. At the national level, a 10 μg/m3 increase in the two-day moving average concentrations (lag 01) of PM10 was associated with 0.45% [95% posterior interval (PI), 0.15% to 0.76%], 0.17% (95% PI, −0.09% to 0.43%), 0.55% (95% PI, 0.15% to 0.96%) and 0.25% (95%PI, −0.05% to 0.56%) increases in total mortality for winter, spring, summer and fall, respectively. For the smoothly-varying plots of seasonality, we identified a two-peak pattern in winter and summer. The observed seasonal pattern was generally insensitive to model specifications. Our analyses suggest that the acute effect of particulate air pollution could vary by seasons with the largest effect in winter and summer in China. To our knowledge, this is the first multicity study in developing countries to analyze the seasonal variations of PM-related health effects. PMID:23500824

The chemical effects from acute exposures to uranium hexafluoride are compared to the nonstochastic effects from acute radiation doses of 25 rems to the whole body and 300 rems to the thyroid. The analysis concludes that an intake of about 10 mg of uranium in soluble form is roughly comparable, in terms of early effects, to an acute whole body dose of 25 rems because both are just below the threshold for significant nonstochastic effects. Similarly, an exposure to hydrogen fluoride at a concentration of 25 mg/m 3 for 30 minutes is roughly comparable because there would be no significant nonstochastic effects. For times t other than 30 minutes, the concentration C of hydrogen fluoride considered to have the same effect can be calculated using a quadratic equation: C = 25 mg/m 3 (30 min/t). The purpose of these analyses is to provide information for developing design and siting guideline based on chemical toxicity for enrichment plants using uranium hexafluoride. These guidelines are to be similar, in terms of stochastic health effects, to criteria in NRC regulations of nuclear power plants, which are based on radiation doses. 26 refs., 1 fig., 5 tabs

To evaluate practice nurse (PN) and health visitor (HV) management of patients with acute minor illnesses, monitor the effect on general practitioner (GP) workload, and describe the range of conditions seen by nurses. Patients requesting 'urgent' appointments (within 24 hours) were offered consultations with a PN or HV trained in the management of acute minor illness. Comparative data were collected before and after the establishment of the acute minor illness service. A general practice in Nottingham, England. Patient satisfaction, consultation rate, prescriptions, investigations, referrals and urgent re-consultations for the same condition within 2 weeks. About 2056 urgent consultations were recorded in the study period, of which 332 (16.1%) were seen by PNs and 46 (2.2%) by a HV. High levels of patient satisfaction were reported for all health professionals. Patients seeing the HV reported higher levels of satisfaction than those consulting GPs (P=0.033) and PNs (P=0.010). There was no difference by health professional for prescription rates (P=0.76), re-consultations (P=0.14), or referrals to secondary care (P=0.07). General practitioners were more likely to initiate further investigations than the PNs or HV (P manage patients with a range of conditions. General practitioner workload can be reduced while maintaining high patient satisfaction levels.

Some studies have begun to show benefits of brief in-person mind-body skills training. We evaluated the effects of 1-hour online elective mind-body skills training for health professionals on mindfulness, resilience, and empathy. Between May and November, 2014, we described enrollees for the most popular 1-hour modules in a new online mind-body skills training program; compared enrollees' baseline stress and burnout to normative samples; and assessed acute changes in mindfulness, resilience, and empathy. The 513 enrollees included dietitians, nurses, physicians, social workers, clinical trainees, and health researchers; about 1/4 were trainees. The most popular modules were the following: Introduction to Stress, Resilience, and the Relaxation Response (n = 261); Autogenic Training (n = 250); Guided Imagery and Hypnosis for Pain, Insomnia, and Changing Habits (n = 112); Introduction to Mindfulness (n = 112); and Mindfulness in Daily Life (n = 102). Initially, most enrollees met threshold criteria for burnout and reported moderate to high stress levels. Completing 1-hour modules was associated with significant acute improvements in stress (P training reaches diverse, stressed health professionals and is associated with acute improvements in stress, mindfulness, empathy, and resilience. Additional research is warranted to compare the long-term cost-effectiveness of different doses of online and in-person mind-body skills training for health professionals. © The Author(s) 2015.

There have been no multicity studies on the acute effects of air pollution on stroke mortality in China. This study was undertaken to examine the associations between daily stroke mortality and outdoor air pollution (particulate matter air pollution with daily stroke mortality. Air pollution was associated with daily stroke mortality in 8 Chinese cities. In the combined analysis, an increase of 10 μg/m(3) of 2-day moving average concentrations of particulate matter air pollution and risk of stroke mortality. To our knowledge, this is the first multicity study in China, or even in other developing countries, to report the acute effect of air pollution on stroke mortality. Our results contribute to very limited data on the effect of air pollution on stroke for high-exposure settings typical in developing countries.

This paper describes health and environmental impacts of coal-fired electric power plants. Effects on man, agriculture, and natural ecosystems are considered. These effects may result from direct impacts or exposures via air, water, and food chains. The paper is organized by geographical extent of effect. Occupational health impacts and local environmental effects such as noise and solid waste leachate are treated first. Then, regional effects of air pollution, including acid rain, are analyzed. Finally, potential global impacts are examined. Occupational health concerns considered include exposure to noise, dust, asbestos, mercury, and combustion products, and resulting injury and disease. Local effects considered include noise; air and water emissions of coal storage piles, solid waste operations, and cooling systems. Air pollution, once an acute local problem, is now a regional concern. Acute and chronic direct health effects are considered. Special attention is given to potential effects of radionuclides in coal and of acid rain. Finally, potential global impacts associated with carbon dioxide emissions are considered. 88 references, 9 tables

Air pollution and climate change have become key environmental and public health problems around the world, which poses serious threat to human health. How to assess and mitigate the health risks and increase the adaptation of the public have become an urgent topic of research in this area. The six papers in this issue will provide important and rich information on design, analysis method, indicator selection and setting about acute health risk assessment and adaptation study of air pollution and climate change in China, reflecting the advanced conceptions of multi-center and area-specific study and multi-pollutant causing acute effect study. However, the number and type of the cities included in these studies were still limited. In future, researchers should further expand detailed multi-center and multi-area study coverage, conduct area specific predicting and early warning study and strengthen adaptation study.

Full Text Available BACKGROUND: Natural health products (NHP use may have implications with respect to adverse effects, drug interactions and adherence yet the prevalence of NHP use by patients with acute cardiovascular disease and the best method to ascertain this information is unknown. OBJECTIVE: To identify the best method to ascertain information on NHP, and the prevalence of use in a population with acute cardiovascular disease. METHODS: Structured interviews were conducted with a convenience sample of consecutive patients admitted with acute cardiovascular disease to the University of Alberta Hospital during January 2009. NHP use was explored using structured and open-ended questions based on Health Canada's definition of NHP. The medical record was reviewed, and documentation of NHP use by physicians, nurses, and pharmacists, compared against the gold-standard structured interview. RESULTS: 88 patients were interviewed (mean age 62 years, standard deviation [SD 14]; 80% male; 41% admitted for acute coronary syndromes. Common co-morbidities included hypertension (59%, diabetes (26% and renal impairment (19%. NHP use was common (78% of patients and 75% of NHP users reported daily use. The category of NHP most commonly used was vitamins and minerals (73% followed by herbal products (20%, traditional medicines including Chinese medicines (9%, homeopathic preparations (1% and other products including amino acids, essential fatty acids and probiotics (35%. In a multivariable model, only older age was associated with increased NHP use (OR 1.5 per age decile [95%CI 1.03 to 2.2]. When compared to the interview, the highest rate of NHP documentation was the pharmacist history (41%. NHP were documented in 22% of patients by the physician and 19% by the nurse. CONCLUSIONS: NHP use is common in patients admitted with acute cardiovascular disease. However, health professionals do not commonly identify NHP as part of the medication profile despite its potential importance

Disinvestment from inefficient or ineffective health services is a growing priority for health care systems. Provision of allied health services over the weekend is now commonplace despite a relative paucity of evidence supporting their provision. The relatively high cost of providing this service combined with the paucity of evidence supporting its provision makes this a potential candidate for disinvestment so that resources consumed can be used in other areas. This study aims to determine the effectiveness, cost-effectiveness and safety of the current model of weekend allied health service and a new stakeholder-driven model of weekend allied health service delivery on acute medical and surgical wards compared to having no weekend allied health service. Two stepped wedge, cluster randomised trials of weekend allied health services will be conducted in six acute medical/surgical wards across two public metropolitan hospitals in Melbourne (Australia). Wards have been chosen to participate by management teams at each hospital. The allied health services to be investigated will include physiotherapy, occupational therapy, speech therapy, dietetics, social work and allied health assistants. At baseline, all wards will be receiving weekend allied health services. Study 1 intervention will be the sequential disinvestment (roll-in) of the current weekend allied health service model from each participating ward in monthly intervals and study 2 will be the roll-out of a new stakeholder-driven model of weekend allied health service delivery. The order in which weekend allied health services will be rolled in and out amongst participating wards will be determined randomly. This trial will be conducted in each of the two participating hospitals at a different time interval. Primary outcomes will be length of stay, rate of unplanned hospital readmission within 28 days and rate of adverse events. Secondary outcomes will be number of complaints and compliments, staff absenteeism

As part of their core mission, public health agencies attend to a wide range of disease and health threats, including those that require routine, acute, and emergency responses. While each incident is unique, the number and type of response activities are finite; therefore, through comparative analysis, we can learn about commonalities in the response patterns that could improve predictions and expectations regarding the resources and capabilities required to respond to future acute events. In this study, we interviewed representatives from more than 120 local health departments regarding their recent experiences with real-world acute public health incidents, such as infectious disease outbreaks, severe weather events, chemical spills, and bioterrorism threats. We collected highly structured data on key aspects of the incident and the public health response, particularly focusing on the public health activities initiated and community partners engaged in the response efforts. As a result, we are able to make comparisons across event types, create response profiles, and identify functional and structural response patterns that have import for future public health preparedness and response. Our study contributes to clarifying the complexity of public health response systems and our analysis reveals the ways in which these systems are adaptive to the character of the threat, resulting in differential activation of functions and partners based on the type of incident. Continued and rigorous examination of the experiences of health departments throughout the nation will refine our very understanding of what the public health response system is, will enable the identification of organizational and event inputs to performance, and will allow for the construction of rich, relevant, and practical models of response operations that can be employed to strengthen public health systems.

La Vecchia, G Marina; Maestrelli, Piero

2011-01-01

This paper describes some of the recent developments in the control technology to enhance capability of Pulse Gas Metal Arc Welding. Friction Stir Welding (FSW) processing has been also considered. FSW is a new solid-state joining technique. Heat generated by friction at the rotating tool softens the material being welded. FSW can be considered a green and energy-efficient technique without deleterious fumes, gas, radiation, and noise. Application of new welding processes is limited and studies on health effects in exposed workers are lacking. Acute and chronic health effects of conventional welding have been described. Metal fume fever and cross-shift decline of lung function are the main acute respiratory effects. Skin and eyes may be affected by heat, electricity and UV radiations. Chronic effects on respiratory system include chronic bronchitis, a benign pneumoconiosis (siderosis), asthma, and a possible increase in the incidence of lung cancer. Pulmonary infections are increased in terms of severity, duration, and frequency among welders.

Acute otitis media causes discomfort to children and inconvenience to their parents. This study evaluated the quality of life in children with recurrent acute otitis media aged less than 24 months. Quality of life was evaluated in 149 children aged 10 to 24 months who were referred to the Oulu University Hospital on account of recurrent acute otitis media. The children were treated with or without surgery. Age-matched controls were selected randomly from the general child population. Parents completed the Child Health Questionnaire. The children with recurrent acute otitis media had a significantly poorer quality of life than control children. The control children with a history of a few acute otitis media episodes had a significantly poorer quality of life than those without any such history. The quality of life of the children with recurrent acute otitis media improved during the one-year follow up, regardless of the treatment, but did not reach the same level as healthy children. Acute otitis media detracted from quality of life when a generic measure was used. The mode of treatment used to prevent further recurrences of acute otitis media did not influence quality of life improvement.

The effects of acute stress on performance: implications for health professions education.

LeBlanc, Vicki R

2009-10-01

This paper is a review of representative research on the impact of acute stressors on the clinical performance of individuals and teams. The Sciences Citation Index, Medline, and Psychinfo were used to search for articles up to and including 2008. The search terms were stress/tension/arousal/anxiety/cortisol/threat, cognition/skills/memory/attention/problem solving/decision making/performance, stress reduction/stress exposure/stress management/stress inoculation, and health professionals/medicine/medical students/residents/physicians/teams. The search was limited to papers in English from all developed countries. Secondary references were selected from primary papers. Elevated stress levels can impede performance on tasks that require divided attention, working memory, retrieval of information from memory, and decision making. These effects appear to be determined by the individual's appraisal of the demands and resources of a situation, the relationship between the stressor and the task, and factors such as coping styles, locus of control, and social supports. Given the potential negative impact of stress on performance, and the individualistic way in which people respond, medical educators might want to consider avenues for training learners in stress management. More research is needed to fully understand the contributions of personal factors such as coping style and locus of control, as well as the relationship of perceptions of stress to issues such as fatigue.

Periodic, well timed exposure to light is important for our health and wellbeing. Light, in particular in the blue part of the spectrum, is thought to affect alertness both indirectly, by modifying circadian rhythms, and directly, giving rise to acute effects. We performed a systematic review of empirical studies on direct, acute effects of light on alertness to evaluate the reliability of these effects. In total, we identified 68 studies in which either light intensity, spectral distribution, or both were manipulated, and evaluated the effects on behavioral measures of alertness, either subjectively or measured in reaction time performance tasks. The results show that increasing the intensity of polychromatic white light has been found to increase subjective ratings of alertness in a majority of studies, though a substantial proportion of studies failed to find significant effects, possibly due to small sample sizes or high baseline light intensities. The effect of the color temperature of white light on subjective alertness is less clear. Some studies found increased alertness with higher color temperatures, but other studies reported no detrimental effects of filtering out the short wavelengths from the spectrum. Similarly, studies that used monochromatic light exposure showed no systematic pattern for the effects of blue light compared to longer wavelengths. Far fewer studies investigated the effects of light intensity or spectrum on alertness as measured with reaction time tasks and of those, very few reported significant effects. In general, the small sample sizes used in studies on acute alerting effects of light make it difficult to draw definitive conclusions and better powered studies are needed, especially studies that allow for the construction of dose-response curves.

Frequently, research and conference papers explore difficult or problematic areas of practice that can inadvertently render daily nursing accomplishments invisible and create the perception of a discipline in crisis. In this qualitative study, we explore the views of registered nurses about achievements in the workplace and good nursing work in an acute inpatient mental health setting in Sydney, Australia. Mental health nurses were asked a series of questions about their experiences and understanding of what constitutes good nursing work as well as their sense of optimism about their work. A total of 40 structured face-to-face interviews were completed. Among the responses to questions about achievements and good nursing practice, five broad themes were identified: i) teamwork; (ii) interpersonal interactions with patients; (iii) providing practical and holistic support to patients; (iv) patients' mental health improvements; and (v) optimism-pessimism continuum. Findings contribute to a discussion of good nursing work in acute mental health settings, as well as self-perceptions of optimism and hopefulness, which are important contributors to positive, supportive health-care settings and patient recovery. © 2012 The Authors.

Health emergency service teams play an important role in the management of patients with acute coronary syndrome. They have to be educated, equipped, skilful and supported by the entire health care system. The role of county health center in the management of patients with acute coronary syndrome is illustrated in the article, based on the experience acquired at Medimurje County Health Center from Cakovec. The reformed Health Center activities including organization, coordination and linking of teams, population health monitoring at the local level, epidemiologic surveillance, education (active and passive, on both sides of college chair), joint diagnostic and other services, and quality control are discussed in detail. In contrast to a bureaucratic and formal one, a real and innovative reform should take account of necessary changes in the management and organization, not just in standards, rights and obligations. The management protocol for acute coronary syndrome patients is described: setting the main objective (acute coronary disease morbidity and mortality reduction), setting short-term and long-term specific goals, adoption of strategy based on the main objective (education, completion and particular programs pursuit, connecting, collaboration, quality assurance through clinical guidelines and protocols) and other elements, including dignity, leadership, teamwork, adoption and implementation of patient management protocols.

Physiological Basis for Prompt Health Effects

International Nuclear Information System (INIS)

VINCENT, Andrew

2006-01-01

As input to design considerations precluding worker radiological exposure that could lead to an acute health effect from a postulated accident condition, an assessment of the short term health effects was performed. To assure that the impact of the accident scenario on the individual is appropriately considered, both external and internal exposures are included in the evaluation. The focus of this evaluation was to develop a quantitative basis from which to consider the level of exposure postulated in an accident that could lead to a defined physiological impact for short term health effects. This paper does not assess latent health effects of radiological exposure associated with normal operations or emergency response guidelines as these are clearly articulated in existing regulations and ICRP documents. The intent of this paper is to facilitate a dialogue on the appropriate meaning of currently undefined terms such as ''significant'' exposure and ''high-hazard material'' in DSA development

To identify the most common health problems experienced by patients with acute inflammatory arthritis using the International Classification of Functioning, Disability and Health (ICF), and to provide empirical data for the development of an ICF Core Set for acute inflammatory arthritis. Cross-sectional survey of patients with acute inflammatory arthritis of two or more joints requiring admission to an acute hospital. The second level categories of the ICF were used to collect information on patients' health problems. Relative frequencies of impairments, limitations and restrictions in the study population were reported for the ICF components Body Functions, Body Structures, and Activities and Participations. For the component Environmental Factors absolute and relative frequencies of perceived barriers or facilitators were reported. In total, 130 patients were included in the survey. The mean age of the population was 59.9 years (median age 63.0 years), 75% of the patients were female. Most had rheumatoid arthritis (57%) or early inflammatory polyarthritis (22%). Fifty-four second-level ICF categories had a prevalence of 30% or more: 3 (8%) belonged to the component Body Structures and 10 (13%) to the component Body Functions. Most categories were identified in the components Activities and Participation (19; 23%) and Environmental Factors (22; 56%). Patients with acute inflammatory arthritis can be well described by ICF categories and components. This study is the first step towards the development of an ICF Core Set for patients with acute inflammatory arthritis.

To better understand why some people worry more about terrorism compared with others, we measured how much US residents worried about a terrorist event in their area and examined the association of their fears with their concerns about acute and chronic hazards and other correlates. In 2008 (n = 600) and 2010 (n = 651), we performed a random-digit dialing national landline telephone survey. We asked about worries about terrorism and 5 other environmental health hazard issues. We also collected demographic and socioeconomic data. Only 15% worried "a great deal" about a terrorist event in their area and 18% to 33% were greatly concerned about other environmental issues. Fear about acute hazard events was a stronger predictor of a great deal of concern about terrorism than were age, race/ethnicity, gender, educational achievement, and other correlates. Those who worried most about acute environmental health hazard events were most likely to worry about terrorism. Also, those who were older, poorer, Blacks, or Latinos, or who lived in populous urban areas felt they were most vulnerable to terrorist attacks. We recommend methods to involve US citizens as part of disaster planning.

To evaluate the impact of an arts in health programme delivered by a specialised artist within an acute older person's unit. Acute hospitals must meet the increasingly complex needs of older people who experience multiple comorbidities, often including cognitive impairment, either directly related to their admission or longer term conditions, including dementia. A focus on physical illness, efficiency and tasks within an acute care environment can all divert attention from the psychosocial well-being of patients. This focus also decreases capacity for person-centred approaches that acknowledge and value the older person, their life story, relationships and the care context. The importance of arts for health and wellness, including responsiveness to individual need, is well established: however, there is little evidence about its effectiveness for older people in acute hospital settings. We report on a collaborative arts in health programme on an acute medical ward for older people. The qualitative study used collaborative enquiry underpinned by a constructivist approach to evaluate an arts programme that involved participatory art-making activities, customised music, song and illustration work, and enlivening the unit environment. Data sources included observation of art activities, semi-structured interviews with patients and family members, and focus groups with staff. Data were transcribed and thematically analysed using a line by line approach. The programme had positive impacts for the environment, patients, families and staff. The environment exhibited changes as a result of programme outputs; patients and families were engaged and enjoyed activities that aided recovery from illness; and staff also enjoyed activities and importantly learnt new ways of working with patients. An acute care arts in health programme is a carefully nuanced programme where the skills of the arts health worker are critical to success. Utilising such skill, continued focus on person

Gevers, Josette; van Erven, Pierre; de Jonge, Jan; Maas, Maaike; de Jong, Jos

2010-07-01

This paper is a report of a study conducted to determine the combined effect of acute and chronic job demands on acute job strains experienced during medical emergencies, and its consequences for individual teamwork behaviour. Medical emergency personnel have to cope with high job demands, which may cause considerable work stress (i.e. job strains), particularly when both acute and chronic job demands are experienced to be high. This may interfere with effective individual teamwork behaviour. A cross-sectional survey study was conducted in 2008, involving 48 members (doctors and nurses) of medical emergency teams working in the emergency department of a Dutch general hospital. Data were analyzed by means of hierarchical regression analyses. High acute job demands impeded effective teamwork behaviour, but only when they resulted in acute job strain. Acute emotional demands were more likely to result in acute job strain when chronic emotional job demands were also experienced as high. Although acute cognitive and physical strains were also detrimental, effective teamwork behaviour was particularly impeded by acute emotional strain. Acute job strains impair effective individual teamwork behaviour during medical emergencies, and there is urgent need to prevent or reduce a build-up of job strain from high acute and chronic demands, particularly of the emotional kind.

Mechanical Thrombectomy in Patients With Acute Ischemic Stroke: A Health Technology Assessment

Science.gov (United States)

2016-01-01

Background In Ontario, current treatment for eligible patients who have an acute ischemic stroke is intravenous thrombolysis (IVT). However, there are some limitations and contraindications to IVT, and outcomes may not be favourable for patients with stroke caused by a proximal intracranial occlusion. An alternative is mechanical thrombectomy with newer devices, and a number of recent studies have suggested that this treatment is more effective for improving functional independence and clinical outcomes. The objective of this health technology assessment was to evaluate the clinical effectiveness and cost-effectiveness of new-generation mechanical thrombectomy devices (with or without IVT) compared to IVT alone (if eligible) in patients with acute ischemic stroke. Methods We conducted a systematic review of the literature, limited to randomized controlled trials that examined the effectiveness of mechanical thrombectomy using stent retrievers and thromboaspiration devices for patients with acute ischemic stroke. We assessed the quality of the evidence using the GRADE approach. We developed a Markov decision-analytic model to assess the cost-effectiveness of mechanical thrombectomy (with or without IVT) versus IVT alone (if eligible), calculated incremental cost-effectiveness ratios using a 5-year time horizon, and conducted sensitivity analyses to examine the robustness of the estimates. Results There was a substantial, statistically significant difference in rate of functional independence (GRADE: high quality) between those who received mechanical thrombectomy (with or without IVT) and IVT alone (odds ratio [OR] 2.39, 95% confidence interval [CI] 1.88–3.04). We did not observe a difference in mortality (GRADE: moderate quality) (OR 0.80, 95% CI 0.60–1.07) or symptomatic intracerebral hemorrhage (GRADE: moderate quality) (OR 1.11, 95% CI 0.66–1.87). In the base-case cost-utility analysis, which had a 5 year time horizon, the costs and effectiveness for

Left ventricular function was investigated at rest and during exercise by heart catheterization in 15 patients 3-5 months after acute myocardial infarction. The effect of 1 mg digoxin i.v. in ten patients was correlated to placebo (saline solution) in five patients. A significant decrease of the left ventricular enddiastolic pressure, increase of left ventricular systolic ejection fraction and a shift of the left ventricular function curve to left upwards was found after digoxin with no changes in the placebo group. This beneficial effect of acute digitalization in patients convalescing from uncomplicated myocardial infarction without clinical signs of manifest heart failure could have therapeutic implication.

Previous national survey research has shown significant deficits in routine postoperative pain management in the UK. This study used an organizational change perspective to explore in detail the organizational challenges faced by three acute pain services in improving postoperative pain management. Case studies were conducted comprising documentary review and semi-structured interviews (71) with anaesthetists, surgeons, nurses, other health professionals, and managers working in and around three broadly typical acute pain services. Although the precise details differed to some degree, the three acute pain services all faced the same broad range of inter-related challenges identified in the organizational change literature (i.e. structural, political, cultural, educational, emotional, and physical/technological challenges). The services were largely isolated from wider organizational objectives and activities and struggled to engage other health professionals in improving postoperative pain management against a background of limited resources, turbulent organizational change, and inter- and intra-professional politics. Despite considerable efforts they struggled to address these challenges effectively. The literature on organizational change and quality improvement in health care suggests that it is only by addressing the multiple challenges in a comprehensive way across all levels of the organization and health-care system that sustained improvements in patient care can be secured. This helps to explain why the hard work and commitment of acute pain services over the years have not always resulted in significant improvements in routine postoperative pain management for all surgical patients. Using this literature and adopting a whole-organization quality improvement approach tailored to local circumstances may produce a step-change in the quality of routine postoperative pain management.

Poor communication in a patient’s discharge can result in post hospital adverse events, readmission, and mortality. Because of the gravity of these problems, discharge planning has been emphasized as a potential solution. The purpose of this paper is to identify communication barriers to effective discharge planning in an acute care unit of a tertiary care center and to suggest solutions to these barriers. Methods: Health care providers provided comments to a single open-ended question: “What are the communication barriers between the different health care providers that limit an effective discharge of patients from Unit 36?” We conducted qualitative thematic analysis by identifying themes related to communication barriers affecting a successful discharge process. Results: Three broad themes related to barriers to the discharge process were identified: communication, lack of role clarity and lack of resources. We also identified two themes for opportunities for improvement, ie, structure and function of the medical team and need for leadership. Conclusion: While it was evident that poor communication was an overarching barrier identified by health care providers, other themes emerged. In an effort to increase inter-team communication, “bullet rounds”, a condensed form of discharge rounds, were introduced to the medical

The purpose of this study was to examine the effects on humans of exposure to carbon dioxide (CO2) and bioeffluents. In three of the five exposures, the outdoor air supply rate was high enough to remove bioeffluents, resulting in a CO2 level of 500 ppm. Chemically pure CO2 was added...... to this reference condition to create exposure conditions with CO2 at 1,000 ppm or 3,000 ppm. In two further conditions, the outdoor air supply rate was restricted so that the bioeffluent CO2 reached 1,000 ppm or 3,000 ppm. The same twenty-five subjects were exposed for 255 minutes to each condition. Subjective...... ratings, physiological responses and cognitive performance were measured. No statistically significant effects on perceived air quality, acute health symptoms or cognitive performance were seen during exposures when CO2 was added. Exposures to bioeffluents with CO2 at 3,000 ppm reduced perceived air...

More than 30% of patients hospitalized for heart failure are rehospitalized or die within 90 days of discharge. Lower health literacy is associated with mortality among outpatients with chronic heart failure; little is known about this relationship after hospitalization for acute heart failure. Patients hospitalized for acute heart failure and discharged home between November 2010 and June 2013 were followed through December 31, 2013. Nurses administered the Brief Health Literacy Screen at admission; low health literacy was defined as Brief Health Literacy Screen ≤9. The primary outcome was all-cause mortality. Secondary outcomes were time to first rehospitalization and, separately, time to first emergency department visit within 90 days of discharge. Cox proportional hazards models determined their relationships with health literacy, adjusting for age, gender, race, insurance, education, comorbidity, and hospital length of stay. For the 1379 patients, average age was 63.1 years, 566 (41.0%) were female, and 324 (23.5%) had low health literacy. Median follow-up was 20.7 months (interquartile range 12.8 to 29.6 months), and 403 (29.2%) patients died. Adjusted hazard ratio [aHR] for death among patients with LHL was 1.32 (95%confidence interval [CI] 1.05, 1.66, P=0.02) compared to BHLS>9 [corrected].Within 90 days of discharge, there were 415 (30.1%) rehospitalizations and 201 (14.6%) emergency department visits, with no evident association with health literacy. Lower health literacy was associated with increased risk of death after hospitalization for acute heart failure. There was no evident relationship between health literacy and 90-day rehospitalization or emergency department visits. © 2015 The Authors.

The quality of health information in the Internet may be low. This is a concerning issue in cardiovascular diseases which warrant patient self-management. We aimed to assess the quality of Portuguese websites as a source of health information on acute myocardial infarction and stroke. We used the search terms 'enfarte miocardio' and 'acidente vascular cerebral' (Portuguese terms for myocardial infarction and stroke) on Google(®), on April 5th and 7th 2011, respectively, using Internet Explorer(®). The first 200 URL retrieved in each search were independently visited and Portuguese websites in Portuguese language were selected. We analysed and classified 121 websites for structural characteristics, information coverage and accuracy of the web pages with items defined a priori, trustworthiness in general according to the Health on the Net Foundation and regarding treatments using the DISCERN instrument (48 websites). Websites were most frequently commercial (49.5%), not exclusively dedicated to acute myocardial infarction/ stroke (94.2%), and with information on medical facts (59.5%), using images, video or animation (60.3%). Websites' trustworthiness was low. None of the websites displayed the Health on the Net Foundation seal. Acute myocardial infarction/ stroke websites differed in information coverage but the accuracy of the information was acceptable, although often incomplete. The quality of information on acute myocardial infarction/ stroke in Portuguese websites was acceptable. Trustworthiness was low, impairing users' capability of identifying potentially more reliable content.

The therapeutic effect of bee pollens on acute radiation sickness were evaluated by observing the changes in the peripheral white blood cell (PWBC) count, the total activity of superoxide dismutase (SOD) and the levels of lipid peroxides (LPO) in sera of the irradiated rats following P.O. administration of bee pollens. It was found that bee pollens could remarkably help irradiated rats recover from radiation-induced injury. The functions of bee pollens might be summarized as follows: (1) Stimulating Proliferation of PWBC. The PWBC count of the bee pollens group showed no significant difference as compared with the normal control group on the 30 th day postirradiation. (2) Enhancing antioxidative effect of clearing free radicals. The total activity of serum SOD in the bee pollens group increased by 6.48% as compared with the normal control group on the 30 th day after irradiation, and the LPO levels i.e. MDA and POV in sera of the irradiated rats decreased by 54.73% and 21.60% respectively. The result suggests that using bee pollens as antiradiation and health-promoting agents in clinical treatment of acute radiation sickness and during radiotherapy of patients with tumors may has certain practical value.

Full Text Available Abstract Background Universal health coverage through the removal of financial and other barriers to access, particularly for people who are poor, is a global priority. This viewpoint describes the many pathways to catastrophic health expenditure (CHE for patients with Acute Coronary Syndrome (ACS based on two case studies and the thematic analysis of field notes regarding 210 patients and their households from a study based in Kerala, India. Discussion There is evidence of the severe financial impact of non-communicable diseases (NCDs, which is in contradiction to the widely acclaimed Kerala model: Good health at low cost. However, it is important to look beyond the out-of-pocket expenditure (OOPE and CHE to the possible pathways and identify the triggers that make families vulnerable to CHE. The identified pathways include a primary and secondary loop. The primary pathway describes the direct path by which families experience CHE. These include: 1 factors related to the pre-event period that increase the likelihood of experiencing CHE, such as being from the lower socio-economic strata (SES, past financial losses or loans that leave families with no financial shock absorber at the time of illness; 2 factors related to the acute event, diagnosis, treatment and hospitalization and expenditures incurred for the same and; 3 factors related to the post-event period such as loss of gainful employment and means of financing both the acute period and the long-term management particularly through distress financing. The secondary pathway arises from the primary and includes: 1 the impact of distress financing and; 2 the long- and short- term consequences of CHE. These factors ultimately result in a vicious cycle of debt and poverty through non-compliance and repeat acute events. Summary This paper outlines the direct and indirect pathways by which patients with ACS and their families are trapped in a vicious cycle of debt and poverty. It also

2014-08-01

Distribution and marketing of chemicals require appropriate labelling of health, physical and environmental hazards according to the United Nations global harmonisation system (GHS). Labelling for (human) acute toxicity categories is based on experimental findings usually obtained by oral, dermal or inhalative exposure of rodents. There is a strong societal demand for replacing animal experiments conducted for safety assessment of chemicals. Fish embryos are considered as alternative to animal testing and are proposed as predictive model both for environmental and human health effects. Therefore, we tested whether LC50s of the fish embryo acute toxicity test would allow effectively predicting of acute mammalian toxicity categories. A database of published fish embryo LC50 containing 641 compounds was established. For these compounds corresponding rat oral LD50 were identified resulting in 364 compounds for which both fish embryo LC50 and rat LD50 was available. Only a weak correlation of fish embryo LC50 and rat oral LD50 was obtained. Fish embryos were also not able to effectively predict GHS oral acute toxicity categories. We concluded that due to fundamental exposure protocol differences (single oral dose versus water-borne exposure) a reverse dosimetry approach is needed to explore the predictive capacity of fish embryos.

Health Effects of Chronic Arsenic Exposure

Full Text Available Arsenic is a unique element with distinct physical characteristics and toxicity whose importance in public health is well recognized. The toxicity of arsenic varies across its different forms. While the carcinogenicity of arsenic has been confirmed, the mechanisms behind the diseases occurring after acute or chronic exposure to arsenic are not well understood. Inorganic arsenic has been confirmed as a human carcinogen that can induce skin, lung, and bladder cancer. There are also reports of its significant association to liver, prostate, and bladder cancer. Recent studies have also suggested a relationship with diabetes, neurological effects, cardiac disorders, and reproductive organs, but further studies are required to confirm these associations. The majority of research to date has examined cancer incidence after a high exposure to high concentrations of arsenic. However, numerous studies have reported various health effects caused by chronic exposure to low concentrations of arsenic. An assessment of the health effects to arsenic exposure has never been performed in the South Korean population; thus, objective estimates of exposure levels are needed. Data should be collected on the biological exposure level for the total arsenic concentration, and individual arsenic concentration by species. In South Korea, we believe that biological exposure assessment should be the first step, followed by regular health effect assessments.

Therapeutic interpersonal relationships have the capacity to transform and enrich the patients’ experiences. Consequently, with an increasing necessity to focus on patient-centered care, it is imperative for health care professionals to therapeutically engage with patients to improve health-related outcomes. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO databases of peer-reviewed research, limited to the English language with search terms developed to reflect therapeutic interpersonal relationships between health care professionals and patients in the acute care setting. This study found that therapeutic listening, responding to patient emotions and unmet needs, and patient centeredness were key characteristics of strategies for improving therapeutic interpersonal relationships.

Electronic Health Record-Enabled Big-Data Approaches to Nephrotoxin-Associated Acute Kidney Injury Risk Prediction.

Science.gov (United States)

Sutherland, Scott M

2018-06-09

Nephrotoxin-associated acute kidney injury (NTx-AKI) has become one of the most common causes of AKI among hospitalized adults and children; across acute and intensive care populations, exposure to nephrotoxins accounts for 15-25% of AKI. Although some interventions have shown promise in observational studies, no treatments currently exist for NTx-AKI once it occurs. Thus, nearly all effective strategies are aimed at prevention. The primary obstacle to prevention is risk prediction and the determination of which patients are more likely to develop NTx-AKI when exposed to medications with nephrotoxic potential. Historically, traditional statistical modeling has been applied to previously recognized clinical risk factors to identify predictors of NTx-AKI. However, increased electronic health record adoption and the evolution of "big-data" approaches to predictive analytics may offer a unique opportunity to prevent NTx-AKI events. This article describes prior and current approaches to NTx-AKI prediction and offers three novel use cases for electronic health record-enabled NTx-AKI forecasting and risk profiling.

The costs associated with patients discharged with isolated clinician-elicited persistent midline tenderness and negative computed tomography (CT) findings have not been reported. Our aim was to determine the association of acute and post-acute patient and injury characteristics with health resource costs in such patients following road trauma. In a prospective cohort study, road trauma patients presenting with isolated persistent midline cervical tenderness and negative CT, who underwent additional acute imaging with MRI, were recruited. Patients were reviewed in the outpatient spine clinic following discharge, and were followed up at 6 and 12 months post-trauma. Multivariate linear regression was used to assess the association of injury mechanism, clinical assessment, socioeconomic factors and outcome findings with health resource costs generated in the acute hospital and post-acute periods. There were 64 patients recruited, of whom 24 (38%) had cervical spine injury detected on MRI. Of these, 2 patients were managed operatively, 6 were treated in cervical collars and 16 had the cervical spine cleared and were discharged. At 12 months, there were 25 patients (44%) with residual neck pain, and 22 (39%) with neck-related disability. The mean total cost was AUD $10,153 (SD=10,791) and the median was $4015 (IQR: 3044-6709). Transient neurologic deficit, which fully resolved early in the emergency department, was independently associated with higher marginal mean acute costs (represented in the analysis by the β coefficient) by $3521 (95% CI: 50-6880). Low education standard (β coefficient: $5988, 95% CI: 822-13,317), neck pain at 6 months (β coefficient: $4017, 95% CI: 426-9254) and history of transient neurologic deficit (β coefficient: $8471, 95% CI: 1766-18,334) were associated with increased post-acute costs. In a homogeneous group of road trauma patients with non fracture-related persistent midline cervical tenderness, health resource costs varied

Experiences of mental health nursing staff working with voice hearers in an acute setting: An interpretive phenomenological approach.

McMullan, E; Gupta, A; Collins, S C

2018-04-01

WHAT IS KNOWN ON THE SUBJECT?: Community mental health staff and their service users have reported mixed views on the importance of talking about the content of voices. Community staff have reported feeling that they do not have the skills to explore voice content and worry about making things worse. Voice hearers experiencing extreme distress due to the content of their voices can access support through acute inpatient mental health services. No previous studies have focused on the experiences of staff who nurse voice hearers at a time of acute distress. WHAT DOES THIS STUDY ADD TO EXISTING KNOWLEDGE?: MHNs and HSWs working with voice hearers in acute distress report feeling powerless and helpless, as they feel that they cannot lessen the distress experienced by the voice hearer. Despite these difficult feelings, staff report finding ways of coping, including using structured tools to help make sense of their service users' voice-hearing experiences and accessing reflective practice forums. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Due to the current context of increased acuity and limited resources in acute services, there may be a need to further protect time for staff to access reflective practice groups and supervision forums to help them manage the difficult feelings arising from their work with voice hearers. Introduction Mental health nursing (MHN) staff in acute settings work with voice hearers at times of crises when they experience high levels of distress. Previous research has focused on community mental health staff's experiences and their service users views on exploring the content of voices. No studies have explored this from an acute mental health service perspective. Aim This study therefore sought to explore the experiences of staff working with voice hearers in an acute mental health service. Method Due to the exploratory nature of the research, a qualitative design was chosen. Three MHNs and five healthcare support workers (HSWs) were

As polybrominated diphenyl ethers are phased out, numerous compounds are emerging as potential replacement flame retardants for use in consumer and electronic products. Little is known, however, about the neurobehavioral toxicity of these replacements. This study evaluated the neurobehavioral effects of acute or developmental exposure to t-butylphenyl diphenyl phosphate (BPDP), 2-ethylhexyl diphenyl phosphate (EHDP), isodecyl diphenyl phosphate (IDDP), isopropylated phenyl phosphate (IPP), tricresyl phosphate (TMPP; also abbreviated TCP), triphenyl phosphate (TPHP; also abbreviated TPP), tetrabromobisphenol A (TBBPA), tris (2-chloroethyl) phosphate (TCEP), tris (1,3-dichloroisopropyl) phosphate (TDCIPP; also abbreviated TDCPP), tri-o-cresyl phosphate (TOCP), and 2,2-,4,4’-tetrabromodiphenyl ether (BDE-47) in zebrafish (Danio rerio) larvae. Larvae (n≈24 per dose per compound) were exposed to test compounds (0.4 - 120 µM) at sub-teratogenic concentrations either developmentally or acutely, and locomotor activity was assessed at 6 days post fertilization. When given developmentally, all chemicals except BPDP, IDDP and TBBPA produced behavioral effects. When given acutely, all chemicals produced behavioral effects, with TPHP, TBBPA, EHDP, IPP, and BPDP eliciting the most effects at the most concentrations. The results indicate that these replacement flame retardants may have developmental or pharmacological effects on the vertebrate nervous system. This study

This is the second of three reports on the follow-up review of mental health care at Helen Joseph Hospital (HJH). Objectives for the review were to provide realistic estimates of cost for unit activities and to establish a quality assurance cycle that may facilitate cost centre management. The study described and used activity-based costing (ABC) as an approach to analyse the recurrent cost of acute in-patient care for the financial year 2007-08. Fixed (e.g. goods and services, staff salaries) and variable recurrent costs (including laboratory' 'pharmacy') were calculated. Cost per day, per user and per diagnostic group was calculated. While the unit accounted for 4.6% of the hospital's total clinical activity (patient days), the cost of R8.12 million incurred represented only 2.4% of the total hospital expenditure (R341.36 million). Fixed costs constituted 90% of the total cost. For the total number of 520 users that stayed on average 15.4 days, the average cost was R1,023.00 per day and R15748.00 per user. Users with schizophrenia accounted for the most (35%) of the cost, while the care of users with dementia was the most expensive (R23,360.68 per user). Costing of the application of World Health Organization norms for acute care staffing for the unit, projected an average increase of 103% in recurrent costs (R5.1 million), with the bulk (a 267% increase) for nursing. In the absence of other guidelines, aligning clinical activity with the proportion of the hospital's total budget may be an approach to determine what amount should be afforded to acute mental health in-patient care activities in a general regional hospital such as HJH. Despite the potential benefits of ABC, its continued application will require time, infrastructure and staff investment to establish the capacity to maintain routine annual cost analyses for different cost centres.

Intimate partner violence (IPV) often culminates in acute physical injury, sexual assault, and mental health issues. It is crucial to understand the healthcare habits of victims to develop interventions that can drastically improve a victim's quality of life and prevent future abuse. The objective of this study is to mine de-identified and aggregated Electronic Health Record data to identify women's health issues that are potentially associated with IPV. In this study we compared health issues of female domestic abuse victims to female non-domestic abuse victims. The Domestic abuse population contained 5870 patients, while the Non-Domestic Abuse population contained 14,315,140 patients. Explorys provides National Big Data from the entire USA. Statistical analysis identified 2429 terms as significantly more prevalent among victims of domestic abuse, compared to the general population. These terms were classified into broad categories, including acute injury, chronic conditions, substance abuse, mental health, disorders, gynecological and pregnancy related problems.

Mobile Integrated Health (MIH) leverages specially trained paramedics outside of emergency response to bridge gaps in local health care delivery. To evaluate the efficacy of a MIH led transitional care strategy to reduce acute care utilization. This was a retrospective cohort analysis of a quality improvement pilot of patients from an urban, single county EMS, MIH transitional care initiative. We utilized a paramedic/social worker (or social care coordinator) dyad to provide in home assessments, medication review, care coordination, and improve access to care. The primary outcome compared acute care utilization (ED visits, observation stays, inpatient visits) 90days before MIH intervention to 90days after. Of the 203 patients seen by MIH teams, inpatient utilization decreased significantly from 140 hospitalizations pre-MIH to 26 post-MIH (83% reduction, p=0.00). ED and observation stays, however, increased numerically, but neither was significant. (ED 18 to 19 stays, p=0.98; observation stays 95 to 106, p=0.30) Primary care visits increased 15% (p=0.11). In this pilot before/after study, MIH significantly reduces acute care hospitalizations. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Objective: The present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of Crocus sativus L. (saffron using mice in two different regimens of acute and sub-acute administration. Material and Methods: In acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p. were evaluated using forced swim test (FST. In sub-acute study (21 times with 24-h intervals, antidepressant-like effects of oral administration of drugs were examined using FST and tail suspension test (TST. Locomotor activity and motor coordination were studied using open field and rotarod tests, respectively. Results: Acute treatment with crocin (40 mg/kg and crocetin (20 and 40 mg/kg produced antidepressant-like effect in FST without affecting the baseline locomotion in mice. Sub-acute oral administration of crocin significantly decreased immobility time only at the highest dose (100 mg/kg. Crocetin (12.5, 25 and 50 mg/kg was able to decrease immobility time in FST and TST. Locomotor activity and coordination of mice were not affected by crocin or crocetin. Conclusion: Since higher doses of crocin was required to show antidepressant effects, more efficacy of crocetin may be concluded. This observation provides further support for metabolism of crocin to crocetin following oral administration.

Given the well-documented deleterious health effects, poor sleep has become a serious public health concern and increasing efforts are directed toward understanding underlying pathways. One potential mechanism may be stress and its biological correlates; however, studies investigating the effects of poor sleep on a body's capacity to deal with challenges are lacking. The current study thus aimed at testing the effects of sleep quality and quantity on cortisol responses to acute psychosocial stress. A total of 73 college-aged adults (44 females) were investigated. Self-reported sleep behavior was assessed via the Pittsburgh Sleep Quality Index and salivary cortisol responses to the Trier Social Stress Test were measured. In terms of sleep quality, we found a significant three-way interaction, such that relative to bad sleep quality, men who reported fairly good or very good sleep quality showed blunted or exaggerated cortisol responses, respectively, while women's stress responses were less dependent on their self-reported sleep quality. Contrarily, average sleep duration did not appear to impact cortisol stress responses. Lastly, participants who reported daytime dysfunctions (i.e. having trouble staying awake or keeping up enthusiasm) also showed a trend to blunted cortisol stress responses compared to participants who did not experience these types of daytime dysfunctions. Overall, the current study suggests gender-specific stress reactivity dysfunctions as one mechanism linking poor sleep with detrimental physical health outcomes. Furthermore, the observed differential sleep effects may indicate that while the body may be unable to maintain normal hypothalamic-pituitary-adrenal functioning in an acute psychosocial stress situation after falling prey to low sleep quality, it may retain capacities to deal with challenges during extended times of sleep deprivation.

Principles and practical procedures for acute psychological first aid training for personnel without mental health experience.

Most authorities agree that mass disasters leave in their wake a need for some form of acute mental health services. However, a review of current literature on crisis intervention and disaster mental health reveals differing points of view on the methods that should be employed (Raphael, 1986; NIMH, 2002). Nevertheless, there appears to be virtual universal endorsement, by relevant authorities, of the value of acute "psychological first aid" (American Psychiatric Association, 1954; USDHHS, 2004; Raphael, 1986; NIMH, 2002; Institute of Medicine, 2003; WHO, 2003; DoD/VAPTSD, 2004; Ritchie, et al., 2004; Friedman, Hamblin, Foa, & Charney, 2004). Psychological first aid (PFA), as an acute mental health intervention, seems uniquely applicable to public health settings, the workplace, the military, mass disaster venues, and even the demands of more well circumscribed critical incidents, e.g., dealing with the psychological aftermath of accidents, robberies, suicide, homicide, or community violence. In this document, we shall introduce the notion of psychological first aid (PFA) as one aspect of a psychological continuum of care, offer a rudimentary definition of PFA, and provide the reader with a practicalframework for its implementation utilizing the individual psychological first aid (iPFA)format. The goal of this paper is to better prepare public health, public safety, and other disaster response personnel who do not possess formal clinical mental health degrees or specialized training to provide iPFA services to primary and secondary disaster victims.

Good jobs, good pay, better health? The effects of job quality on health among older European workers.

Henseke, Golo

2018-01-01

Using data from the Survey of Health, Ageing and Retirement in Europe, this study presents new evidence on the effects of job quality on the occurrence of severe acute conditions, the level of cardiovascular risk factors, musculoskeletal disorders, mental health, functional disabilities and self-assessed health among workers aged 50+. By combining intrinsic job quality with job insecurity and pay the study maps out multiple potential pathways through which work may affect health and well-being. Levering longitudinal data and external information on early retirement ages allows for accounting of unobserved heterogeneity, selection bias and reverse causality. The empirical findings suggest that inequities in health correlate with inequities in job quality, though a substantial fraction of these associations reflect time-constant unobserved heterogeneity. Still, there is evidence for genuine protective effects of better jobs on musculoskeletal disorders, mental health and general health. The effect could contribute to a substantial number of avoidable disorders among older workers, despite relatively modest effect sizes at the level of individuals. Mental health, in particular, responds to changes in job quality. Selection bias such as the healthy worker effect does not alter the results. But the influence of job quality on health may be transitional among older workers. An in-depth analysis of health dynamics reveals no evidence for persistence.

2015-12-01

Telemedicine is a disruptive innovation within health care settings as consultations take place via audio-visual technology rather than traditional face-to-face. Specialist perceptions and experiences of providing audio-visual consultations in emergency situations, however, are not well understood. The aim of this exploratory study was to describe the experience of medical specialists providing acute stroke decision-making support via telemedicine. Data from the Victorian Stroke Telemedicine (VST) programme were used. The experiences of specialists providing an acute clinical telemedicine service to rural emergency departments were explored, drawing on disruptive innovation theory. Document analysis of programme consultation records, meeting minutes and in-depth individual interviews with three neurologists were analysed using triangulation. Since February 2014, 269 stroke telemedicine consultations with 12 neurologists have occurred. Retention on the roster has varied between 1 and >4 years. Overall, neurologists reported benefits of participation, as they were addressing health equity gaps for rural patients. Negative effects were the unpredictability of consultations impacting on their personal life, the mixed level of experience of colleagues initiating the consult and not knowing patient outcomes since follow-up communication was not routine. Insights into workforce experience and satisfaction were identified to inform strategies to support specialists to adapt to the disruptive innovation of telemedicine. © The Author(s) 2015.

Full Text Available Terrorism is a disruptive man-made disaster event challenging human health and wellbeing. It is a hostile activity which brings about much casualty, even death. It not only causes physical casualties but also brings about psychological morbidity and can lead to long term mental disorders. The effects of terrorist attacks on people’s psychological health covers a wide range such as acute stress symptoms to long term disorders like Post-traumatic Stress Disorder (PTSD. The psychological disorder due to traumatic distress is treated with psychotherapies such as psychosocial intervention, psychological debriefing, psychological first aid care, psychological counseling services, and psychoeducation. Government is supporting state and local public health departments to develop efficient public health preparedness planning programs in case of emergency situations. There are some newer approaches working towards enhancing health security and managing responses to a psychological impact of a disaster event like a terrorist attack.

This study examined the effects of optimism and gratitude on self-reported health behavior adherence, physical functioning and emotional well-being after an acute coronary syndrome (ACS). Among 156 patients, we examined associations between optimism and gratitude measured 2 weeks post-ACS and 6-month outcomes: adherence to medical recommendations, mental and physical health-related quality of life (HRQoL), physical functioning, depressive symptoms and anxiety. Multivariable linear regression models were used, controlling for increasing levels of adjustment. Optimism [β=.11, standard error (S.E.)=.05, P=.038] and gratitude (β=.10, S.E.=.05, P=.027) at 2 weeks were associated with subsequent self-reported adherence to medical recommendations (diet, exercise, medication adherence, stress reduction) at 6 months in fully adjusted models. Two-week optimism and gratitude were associated with improvements in mental HRQoL (optimism: β=.44, S.E.=.13, P=.001; gratitude: β=.33, S.E.=.12, P=.005) and reductions in symptoms of depression (optimism: β=-.11, S.E.=.05, P=.039; gratitude: β=-.10, S.E.=.05, P=.028) and anxiety (optimism: β=-.15, S.E.=.05, P=.004; gratitude: β=-.10, S.E.=.05, P=.034) at 6 months. Optimism and gratitude at 2 weeks post-ACS were associated with higher self-reported adherence and improved emotional well-being 6 months later, independent of negative emotional states. Optimism and gratitude may help recovery from an ACS. Interventions promoting these positive constructs could help improve adherence and well-being. Copyright © 2016 Elsevier Inc.

The unchanged global HIV incidence may be related to ignoring acute HIV infection (AHI). This scoping review examines diagnostic, clinical, and public health implications of identifying and treating persons with AHI. We searched PubMed, in addition to hand-review of key journals identifying research pertaining to AHI detection and treatment. We focused on the relative contribution of AHI to transmission and the diagnostic, clinical, and public health implications. We prioritized research from low- and middle-income countries (LMICs) published in the last fifteen years. Extensive AHI research and limited routine AHI detection and treatment have begun in LMIC. Diagnostic challenges include ease-of-use, suitability for application and distribution in LMIC, and throughput for high-volume testing. Risk score algorithms have been used in LMIC to screen for AHI among individuals with behavioural and clinical characteristics more often associated with AHI. However, algorithms have not been implemented outside research settings. From a clinical perspective, there are substantial immunological and virological benefits to identifying and treating persons with AHI - evading the irreversible damage to host immune systems and seeding of viral reservoirs that occurs during untreated acute infection. The therapeutic benefits require rapid initiation of antiretrovirals, a logistical challenge in the absence of point-of-care testing. From a public health perspective, AHI diagnosis and treatment is critical to: decrease transmission via viral load reduction and behavioural interventions; improve pre-exposure prophylaxis outcomes by avoiding treatment initiation for HIV-seronegative persons with AHI; and, enhance partner services via notification for persons recently exposed or likely transmitting. There are undeniable clinical and public health benefits to AHI detection and treatment, but also substantial diagnostic and logistical barriers to implementation and scale-up. Effective

Full Text Available Objective: With increasing survival rates in childhood acute lymphocytic leukemia (ALL, the long-term side effects of treatment have become important. Our aim was to investigate health-related quality of life, depression, anxiety, and self-image among ALL survivors. Materials and Methods: Fifty patients diagnosed with ALL and their siblings were enrolled. The Kovacs Children’s Depression Inventory, State-Trait Anxiety Inventory, Offer Self-Image Questionnaire, and Pediatric Quality of Life InventoryTM were used for collecting data. ANOVA tests were used to determine if there were any significant differences between groups. Results: ALL survivors had higher depression, more anxiety symptoms, lower quality of life, and more negative self-image when compared to their siblings. Conclusion: Continuous diagnostic and interventional mental health services might be necessary for possible emotional side effects of treatment during and after the treatment. Rehabilitation and followup programs should be implemented for children during and after treatment for ALL.

Case Report has presented health effects of high level of irradiation with gamma rays from 192 Ir on the patient M. L. during 21 years after an incident. The main purpose was to investigate long time consequences of partial high level irradiation on human health. Locally, short-term irradiation with high, deadly dose, caused acute radiation syndrome with reversible disorder of function of the individual, most exposed, organs. Frequency of chromosomal aberrations (dicentric), characteristic for direct irradiation, was increased. However, dicentric analyzes did not give expected result for an acute radioactivity illness. Radio-dermatitis had begun already after the incident, while changes on the heart began gradually, not earlier than six months, up to two years after the incident. Irradiated parts of the patient skin have been changed with auto-transplanted skin and appropriate therapy had been taken. More than two decades after the irradiation, system (leukemia) nor solitary tumor on near organs (liver, heart, lungs, bones) did not happened. Radiation illness did not happened in spite of very large dose, because impacts were local and body was uneven irradiated. Also, an appropriate therapy was organized and potential illness did not happen. (authors)

The well-known changes in modern lifestyle habits including over nutrition and physical inactivity have led to striking adverse effects on public health (e.g., obesity, diabetes, and metabolic syndrome) over recent decades. One noticeable consequence is exaggerated and prolonged state of postprandial hyperlipemia due to the ingestion of multiple fat-enriched meals during the course of a day. Postprandial (non-fasting) hyperlipemia is characterized by increased blood levels of exogenous triglycerides (TG) in the form of apolipoprotein (apo) B48-containing TG-rich lipoproteins (TRL), which have a causal role in the pathogenesis and progression of cardiovascular disease (CVD). The cardiovascular benefits of lifestyle modification (healthy diet and exercise) and conventional lipid-lowering therapies (e.g., statins, fibrates, and niacin) could involve their favourable effects on postprandial metabolism. Pharmacologically, niacin has been used as an athero-protective drug for five decades. Studies have since shown that niacin may decrease fasting levels of plasma verylow- density lipoproteins (VLDL), low-density lipoprotein cholesterol (LDL-C), and lipoprotein [a] (Lp[a]), while may increase high-density lipoprotein cholesterol (HDL-C). Herein, the purpose of this review was to provide an update on effects and mechanisms related to the pharmacological actions of niacin on acute hyperlipemia.

Acute ischemic brain injury (stroke, stroke), a leader among the causes of morbidity and mortality in the world. This pathology is one of the most pressing health and social problems that cause enormous economic damage to society, due to the high fatality rate, significant disability and social maladjustment of patients, which is based in most cases are the motor and cognitive impairment. Despite the fact that, currently established risk factors and pathophysiological basis of this disease, the availability of effective methods of diagnosing illness, still a practicing neurologist in some cases difficult to find adequate therapy that could effectively reach a well-established neurological deficit. Therefore the search for treatments that effectively reduce the health and social consequences of vascular damage to the brain, is one of the priority areas of neurology.

2015-05-01

We determine the cost-effectiveness of out-of-hospital continuous positive airway pressure (CPAP) compared with standard care for adults presenting to emergency medical services with acute respiratory failure. We developed an economic model using a United Kingdom health care system perspective to compare the costs and health outcomes of out-of-hospital CPAP to standard care (inhospital noninvasive ventilation) when applied to a hypothetical cohort of patients with acute respiratory failure. The model assigned each patient a probability of intubation or death, depending on the patient's characteristics and whether he or she had out-of-hospital CPAP or standard care. The patients who survived accrued lifetime quality-adjusted life-years (QALYs) and health care costs according to their age and sex. Costs were accrued through intervention and hospital treatment costs, which depended on patient outcomes. All results were converted into US dollars, using the Organisation for Economic Co-operation and Development purchasing power parities rates. Out-of-hospital CPAP was more effective than standard care but was also more expensive, with an incremental cost-effectiveness ratio of £20,514 per QALY ($29,720/QALY) and a 49.5% probability of being cost-effective at the £20,000 per QALY ($29,000/QALY) threshold. The probability of out-of-hospital CPAP's being cost-effective at the £20,000 per QALY ($29,000/QALY) threshold depended on the incidence of eligible patients and varied from 35.4% when a low estimate of incidence was used to 93.8% with a high estimate. Variation in the incidence of eligible patients also had a marked influence on the expected value of sample information for a future randomized trial. The cost-effectiveness of out-of-hospital CPAP is uncertain. The incidence of patients eligible for out-of-hospital CPAP appears to be the key determinant of cost-effectiveness.

To provide an adequate level of protection for humans from exposure to radio-frequency (RF) electromagnetic fields (EMF) and to assure that any adverse health effects are avoided. The basic restrictions in terms of the specific energy absorption rate (SAR) were prescribed by IEEE and ICNIRP. An example of a therapeutic application of non-ionizing EMF is hyperthermia (HT), in which intense RF energy is focused at a target region. Deep HT in the head and neck (H and N) region involves inducing energy at 434 MHz for 60 min on target. Still, stray exposure of the brain is considerable, but to date only very limited side-effects were observed. The objective of this study is to investigate the stringency of the current basic restrictions by relating the induced EM dose in the brain of patients treated with deep head and neck (H and N) HT to the scored acute health effects. We performed a simulation study to calculate the induced peak 10 g spatial-averaged SAR (psSAR 10g ) in the brains of 16 selected H and N patients who received the highest SAR exposure in the brain, i.e. who had the minimum brain-target distance and received high forwarded power during treatment. The results show that the maximum induced SAR in the brain of the patients can exceed the current basic restrictions (IEEE and ICNIRP) on psSAR 10g for occupational environments by 14 times. Even considering the high local SAR in the brain, evaluation of acute effects by the common toxicity criteria (CTC) scores revealed no indication of a serious acute neurological effect. In addition, this study provides pioneering quantitative human data on the association between maximum brain SAR level and acute adverse effects when brains are exposed to prolonged RF EMF. (paper)

An acute health effect of people living near the petrochemical industrial estate in Thailand was assessed using a panel study design. The populations in communities near the petrochemical industrial estates were recruited. The daily air pollutant concentrations, daily percentage of respiratory and other health symptoms reported were collected for 63 days. The effect of air pollutants to reported symptoms of people were estimated by adjusted odds ratios and 95% confidence interval using binary logistic regression. The significant associations were found with the adjusted odds ratios of 38.01 for wheezing, 18.63 for shortness of breath, 4.30 for eye irritation and 3.58 for dizziness for total volatile organic compounds (Total VOCs). The adjusted odds ratio for carbon monoxide (CO2) was 7.71 for cough, 4.55 for eye irritation and 3.53 for weakness and the adjusted odds ratio for ozone (O3) was 1.02 for nose congestion, sore throat and 1.05 for phlegm. The results showed that the people living near petrochemical industrial estate had acute adverse health effects, shortness of breath, eye irritation, dizziness, cough, nose congestion, sore throat, phlegm and weakness from exposure to industrial air pollutants.

Background: Conflicting recommendations exist related to which facial protection should be used by health care workers to prevent transmission of acute respiratory infections, including pandemic influenza. We performed a systematic review of both clinical and surrogate exposure data comparing N95 respirators and surgical masks for the prevention of transmissible acute respiratory infections. Methods: We searched various electronic databases and the grey literature for relevant studies published from January 1990 to December 2014. Randomized controlled trials (RCTs), cohort studies and case–control studies that included data on health care workers wearing N95 respirators and surgical masks to prevent acute respiratory infections were included in the meta-analysis. Surrogate exposure studies comparing N95 respirators and surgical masks using manikins or adult volunteers under simulated conditions were summarized separately. Outcomes from clinical studies were laboratory-confirmed respiratory infection, influenza-like illness and workplace absenteeism. Outcomes from surrogate exposure studies were filter penetration, face-seal leakage and total inward leakage. Results: We identified 6 clinical studies (3 RCTs, 1 cohort study and 2 case–control studies) and 23 surrogate exposure studies. In the meta-analysis of the clinical studies, we found no significant difference between N95 respirators and surgical masks in associated risk of (a) laboratory-confirmed respiratory infection (RCTs: odds ratio [OR] 0.89, 95% confidence interval [CI] 0.64–1.24; cohort study: OR 0.43, 95% CI 0.03–6.41; case–control studies: OR 0.91, 95% CI 0.25–3.36); (b) influenza-like illness (RCTs: OR 0.51, 95% CI 0.19–1.41); or (c) reported workplace absenteeism (RCT: OR 0.92, 95% CI 0.57–1.50). In the surrogate exposure studies, N95 respirators were associated with less filter penetration, less face-seal leakage and less total inward leakage under laboratory experimental conditions

In the meta-analysis of the clinical studies, we found no significant difference between N95 respirators and surgical masks in associated risk of (a) laboratory-confirmed respiratory infection (RCTs: odds ratio [OR] 0.89, 95% confidence interval [CI] 0.64-1.24; cohort study: OR 0.43, 95% CI 0.03-6.41; case-control studies: OR 0.91, 95% CI 0.25-3.36); (b) influenza-like illness (RCTs: OR 0.51, 95% CI 0.19-1.41); or (c) reported workplace absenteeism (RCT: OR 0.92, 95% CI 0.57-1.50). In the surrogate exposure studies, N95 respirators were associated with less filter penetration, less face-seal leakage and less total inward leakage under laboratory experimental conditions, compared with surgical masks. Although N95

An economic evaluation of the potential incremental benefits of intravenous tissue plasminogen activator (tPA) versus streptokinase (SK) for treatment of acute myocardial infarction. Cost effectiveness analysis from a third-party payer perspective (Ontario Ministry of Health). ECONOMIC INPUTS: Fully allocated costs for cardiovascular procedures and hospitalization for myocardial infarction were obtained anonymously for four Ontario teaching hospitals and converted to 1988 Canadian dollars. Professional charges were taken from the provincial health insurance fee schedule and drug costs obtained from the manufacturers. CLINICAL INPUTS: The baseline analysis was for nonelderly patients with uncomplicated myocardial infarctions; sensitivity analyses allowed extrapolation to higher risk subgroups. Short and longer term mortality and short term invasive procedure rates were estimated using data from clinical trials. If tPA achieves a 1% short term mortality advantage over SK with no advantages for other survivors, cost per life-year gained can be comparable to other cardiovascular interventions at $58,600. In the absence of immediate survival advantages, but assuming greater left ventricular preservation, the constant annual hazard rate advantage must be about 0.5% per year for competitive cost effectiveness ratios. A full range of projections is presented to help guide the policy decisions that will arise in the wake of the Global Utilization of SK and tPA for Occluded Coronary Arteries (GUSTO) trial. The analysis also illustrates the general importance of considering longer term effects of in-hospital therapies for acute myocardial infarction.

Health Shocks and Retirement:

DEFF Research Database (Denmark)

Datta Gupta, Nabanita; Larsen, Mona

We investigate the effect of an acute health shock on retirement among elderly male workers in Denmark, 1991-1999, and in particular whether various welfare state programs and institutions impinge on the retirement effect. The results show that an acute health event increases the retirement chances...... significant. For the most part, the retirement effect following a health shock seems to be immune to the availability of a multitude of government programs for older workers in Denmark....... benefits in Denmark nor by the promotion of corporate social responsibility initiatives since the mid-1990s. In the late 1990s, however, the retirement rate following a health shock is reduced to 3% with the introduction of the subsidized employment program (fleksjob) but this effect is not strongly...

Domestic violence and abuse: an exploration and evaluation of a domestic abuse nurse specialist role in acute health care services.

2017-08-01

The aim of this study was to explore the experiences of clinical staff in responding to disclosure of domestic violence and abuse, and to evaluate the effectiveness of training and support provided by a dedicated Domestic Abuse Nurse Specialist across one acute National Health Service Trust in the UK. The impact of domestic violence and abuse is well documented and is far reaching. Health care professionals have a key role to play in the effective identification and management of abuse across a range of settings. However, there is a paucity of evidence regarding the constituents of effective support for practitioners within wider nonemergency hospital-based services. A qualitative approach semi-structured interviews (n = 11) with clinical staff based in one acute care Trust in the UK. Interviews were informed by an interview guide and analysed using the Framework approach. The organisation of the nurse specialist role facilitated a more cohesive approach to management at an organisational level with training and ongoing support identified as key facets of the role by practitioners. Time constraints were apparent in terms of staff training and this raises questions with regard to the status continuing professional development around domestic violence and abuse. Domestic violence and abuse continues to exert a significant and detrimental impact on the lives and health of those who encounter abuse. Health care services in the UK and globally are increasingly on the frontline in terms of identification and management of domestic violence and abuse. This is coupled with the growing recognition of the need for adequate support structures to be in place to facilitate practitioners in providing effective care for survivors of domestic violence and abuse. This study provides an approach to the expansion of existing models and one which has the potential for further exploration and application in similar settings. © 2016 John Wiley & Sons Ltd.

Quality Assessment of Acute Inpatient Pain Management in an Academic Health Center.

Lin, Richard J; Reid, M Carrington; Chused, Amy E; Evans, Arthur T

2016-02-01

The quality of acute inpatient pain management remains suboptimal and poorly understood. In this retrospective study, we analyze acute pain management practice in a large academic health center using several quality indicators. Not surprisingly, despite high rate of pain assessment, many patients still have frequent, prolonged, and unrelieved severe pain episodes. Upon examination of naloxone administration, we identify potential inappropriate opioid prescription practices such as the use of wrong opioids in hepatic and renal failure and simultaneous use of multiple short-acting opioids. Most importantly, we find that chronic opioid users appear to suffer the most in terms of undertreatment of pain as well as opioid overdose, highlighting the urgent need to target this underserved population of patients. © The Author(s) 2014.

Spinal manual therapy (SMT) is a popular treatment option for low back pain (LBP). The aim of our analysis was to evaluate the effects of manual therapy delivered by general practitioners and ambulatory orthopedic surgeons in routine care on follow up consultations, sick leave, health service utilization and costs for acute LBP compared to matched patients not receiving manual therapy. This is a propensity score matched cohort study based on health claims data. We identified a total of 113.652 adult patients with acute LBP and no coded red flags of whom 21.021 (18%) received SMT by physicians. In the final analysis 17.965 patients in each group could be matched. Balance on patients' coded characteristics, comorbidity and prior health service utilization was achieved. The provision of SMT for acute LBP had no relevant impact on follow up visits and days of sick leave for LBP in the index billing period and the following year. SMT was associated with a higher proportion of imaging studies for LBP (30.6% vs. 23%, SMD: 0.164 [95% CI 0.143-0.185]). SMT did not lead to meaningful savings by replacing other health services for LBP. SMT for acute non-specific LBP in routine care was not clinically meaningful effective to reduce sick leave and reconsultation rates compared to no SMT and did not lead to meaningful savings by replacing other health services from the perspective of health insurance. This does not imply that SMT is ineffective but might reflect a problem with selection of suitable patients and the quality and quantity of SMT in routine care. National Manual Medicine societies should state clearly that imaging is not routinely needed prior to SMT in patients with low suspicion of presence of red flags and monitor the quality of provided services.

Although the rise in health costs is a widely debated issue, in Switzerland it was until recently taken for granted that patients are given the best available treatment regardless of cost. An example of a disease requiring costly treatment is acute myelogenous leukaemia (AML). To relate cost to benefit we calculated expenditure per life years gained. To assess costs we determined the real cost of treatment up to total remission, followed by consolidation or withdrawal of treatment or death. For survival time exceeding the 2-year observation period we used data from recent literature. The average cost of treatment ranges up to 107,592 Swiss francs (CHF). In 1997 we treated 23 leukaemia patients at Zurich University Hospital and gained a total of 210 life years. This represents an average cost of CHF 11,741 per life year gained. Chief cost items were therapy and personnel costs for nursing staff, followed by hotel business and personnel costs for doctors and diagnosis. Our results for AML treatment are far removed from the $61,500 ranging up to $166,000 discussed in the literature as the "critical" QALY (quality adjusted life years) value. This is the first time the actual costs of AML therapy have been shown for a Swiss cohort. Despite high initial treatment costs and success only in a limited number of patients, the expenditure per QALY is surprisingly low and shows clearly the effectiveness of apparently costly acute medicine.

Communication in healthcare settings has recently received significant attention in the literature. However, there continues to be a large gap in current understanding of the effectiveness of different communication channels used in acute healthcare settings, particularly in the context of infection prevention and control (IPC). To explore and evaluate the main communication channels used within hospitals to communicate with healthcare workers (HCWs) and to propose practical recommendations. Critical review of the main communication channels used within acute health care to communicate information to HCWs, and analysis of their impact on practice. The analysis covers verbal communications, standardization via guidelines, education and training, electronic communications and marketing strategies. Traditional communication channels have not been successful in changing and sustaining best practice in IPC, but newer approaches (electronic messages and marketing) also have pitfalls. A few simple recommendations are made in relation to the development, implementation and evaluation of communications to HCWs; top-down vs bottom-up communications; and the involvement of HCWs, particularly ward personnel.

Radio frequencies are suspected to produce health effects. Concerning the mobile phone technology, according to position during use (close to the head), possible effects of radio frequencies on the central nervous system have to be evaluated. Previous works showed contradictory results, possibly due to experimental design diversity. In the framework of R.A.M.P. 2001 project, we evaluated possible effect of a 900 MHz GSM exposure on the central nervous system of rat at a structural, a functional and a behavioral level after acute or sub-chronic exposures. Rats were exposed using a loop antenna system to different S.A.R. levels and durations, according to results of the French C.O.M.O.B.I.O. 2001 project. A functional effect was found (modification of the cerebral activity and increase of the glia surface) after an acute exposure, even at a low level of brain averaged S.A.R. (1.5 W/kg). No cumulative effect was observed after a sub-chronic exposure (same amplitude of the effect). No structural or behavioral consequence was noted. We do not conclude on the neurotoxicity of the 900 MHz GSM exposure on the rat brain. Our results do not indicate any health risk. (authors)

In massive hemispheric infarction and edema, surgical decompression...... lowers the risk of death or severe disability defined as a modified Rankin Scale score greater than 4 in selected patients. The majority, around 80%-85% of all ischemic stroke victims, does not fulfill the criteria for revascularization therapy, and also for these patients, there is no effective acute...... therapy. Also there is no established effective acute treatment of spontaneous intracerebral bleeding. Therefore, an effective therapy applicable to all stroke victims is needed.

Honey is recommended for non-specific acute paediatric cough by the Australian guidelines. Current available randomised clinical trials evaluated the effects of a single evening dose of honey, but multiple doses outcomes have never been studied. To evaluate the effects of wildflower honey, given for three subsequent evenings, on non-specific acute paediatric cough, compared to dextromethorphan (DM) and levodropropizine (LDP), which are the most prescribed over-the-counter (OTC) antitussives in Italy. 134 children suffering from non-specific acute cough were randomised to receive for three subsequent evenings a mixture of milk (90ml) and wildflower honey (10ml) or a dose of DM or LDP adjusted for the specific age. The effectiveness was evaluated by a cough questionnaire answered by parents. Primary end-point efficacy was therapeutic success. The latter was defined as a decrease in cough questionnaire score greater than 50% after treatment compared with baseline values. Three children were excluded from the study, as their parents did not complete the questionnaire. Therapeutic success was achieved by 80% in the honey and milk group and 87% in OTC medication group (p=0.25). Milk and honey mixture seems to be at least as effective as DM or LDP in non-specific acute cough in children. These results are in line with previous studies, which reported the health effects of honey on paediatric cough, even if placebo effect cannot be totally excluded. Copyright © 2014 SEICAP.

The inability to monetize the health costs of acute exposures in homes and the benefits of various control options is a barrier to justifying policies and approaches that can reduce exposure and improve health.We synthesized relationships between short-term outdoor concentration changes and health outcomes to estimate the health impacts of short-term in-home exposures. Damage and cost impacts of specific health outcomes were taken from the literature. We assessed the impact of vented and non-vented residential natural gas cooking burners on Southern California occupants for two pollutants (NO₂ and CO).

Nanometer zinc oxide (nano-ZnO) is widely used in diverse industrial and agricultural fields. Due to the extensive contact humans have with these particles, it is crucial to understand the potential effects that nano-ZnO have on human health. Currently, information related to the toxicity and mechanisms of nano-ZnO is limited. The aim of the present study was to investigate acute and cumulative toxic effects of 50-nm unmodified ZnO in mice. This investigation will seek to establish median lethal dose (LD50), a cumulative coefficient, and target organs. The acute and cumulative toxicity was investigated by Karber's method and via a dose-increasing method, respectively. During the experiment, clinical signs, mortality, body weights, hematology, serum biochemistry, gross pathology, organ weight, and histopathology were examined. The LD50 was 5177-mg/kg·bw; the 95% confidence limits for the LD50 were 5116-5238-mg/kg·bw. It could be concluded that the liver, kidney, lung, and gastrointestinal tract were target organs for the 50-nm nano-ZnO acute oral treatment. The cumulative coefficient (K) was 1.9 which indicated that the cumulative toxicity was apparent. The results also indicated that the liver, kidney, lung, and pancrea were target organs for 50-nm nano-ZnO cumulative oral exposure and might be target organs for subchronic and chronic toxicity of oral administered 50-nm ZnO.

Endovascular treatment for acute ischemic stroke with a large vessel occlusion was recently shown to be effective. We aimed to develop a score capable of predicting large vessel occlusion eligible for endovascular treatment in the early hospital management. Retrospective, cohort study. Two tertiary, Swiss stroke centers. Consecutive acute ischemic stroke patients (1,645 patients; Acute STroke Registry and Analysis of Lausanne registry), who had CT angiography within 6 and 12 hours of symptom onset, were categorized according to the occlusion site. Demographic and clinical information was used in logistic regression analysis to derive predictors of large vessel occlusion (defined as intracranial carotid, basilar, and M1 segment of middle cerebral artery occlusions). Based on logistic regression coefficients, an integer score was created and validated internally and externally (848 patients; Bernese Stroke Registry). None. Large vessel occlusions were present in 316 patients (21%) in the derivation and 566 (28%) in the external validation cohort. Five predictors added significantly to the score: National Institute of Health Stroke Scale at admission, hemineglect, female sex, atrial fibrillation, and no history of stroke and prestroke handicap (modified Rankin Scale score, < 2). Diagnostic accuracy in internal and external validation cohorts was excellent (area under the receiver operating characteristic curve, 0.84 both). The score performed slightly better than National Institute of Health Stroke Scale alone regarding prediction error (Wilcoxon signed rank test, p < 0.001) and regarding discriminatory power in derivation and pooled cohorts (area under the receiver operating characteristic curve, 0.81 vs 0.80; DeLong test, p = 0.02). Our score accurately predicts the presence of emergent large vessel occlusions, which are eligible for endovascular treatment. However, incorporation of additional demographic and historical information available on hospital arrival

Categories of adverse health effects from indoor air pollution

There is a lack of precision in the definition of health, which leads to confusion in the assessment of adverse effects arising from indoor air pollution. Adverse health effects range from annoyance to life-threatening conditions. Survey responses suggest that males and females differ in their perception of a healthy person, but both sexes envisage a male in terms of positive fitness, strength, energy and the possession of an athletic body, rather than how long one was likely to live. Psychological fitness was relatively unimportant in describing the health of others, but was rates as very important with respect to one's own health. Mortality statistics tend to obscure the proportion of the population who suffer chronic illness that is not life threatening. Although health is largely determined by genetic constitution, lifestyle and environmental factors, the morale of an individual is also important. A new classification of the adverse effects on health of indoor air pollution is proposed: this includes 'comfort' responses, such as sick building syndrome (category 1); acute chemical effects, the nature of which depends upon the specific intoxicant (category 2B), and perceived chronic grave risk, including cancer causation (category 3). The magnitude of risk in this latter category is imprecise, because its measurement involves the technique of quantitative risk assessment. (author) 1 fig., 2 tabs., 158 refs

The environmental and energy policy in Sweden is aiming to replace fossil energy with renewable sources such as biofuels, e.g., wood Pellets produced from shavings and sawdust of pine and spruce. Reported health effects in the wood processing industries are airway, eye and skin irritation, reduced lung function as well as eczema. The aim of our study was to investigate the prevalence of airway and skin symptoms and measure lung function in a population of pellet operators in the Swedish wood industry. Additional reported acute effects from the airways, eyes, nose and skin were recorded. From May 2004 until April 2005 50 blue-collar workers from four Swedish pellet-producing industries were investigated. The study included a questionnaire about skin and airway symptoms (n=50), acute effect questionnaire (n=67; 44 individuals) as well as a test of the lung function (spirometry) before and after work shift (n=118; 39 individuals). Acute effects questionnaire and spirometry were done one to three times per participants and for the acute effects the worker had to assess their symptoms in the airways, eyes, nose and skin between 6 and 8 times during a day. The results from the symptom questionnaires were compared with reference data from other Swedish studies and the lung function data with a European reference material. Statistical tests used were chi-2-test for the questionnaire, t-test for lung function before shift compared expected values, and for difference in lung function between before and after work shift mixed models with subjects as a random factor. No statistical significant difference was seen for the skin and airway symptoms in the questionnaire. Reported acute effects were seen especially for eye and nose symptoms (table 1). Spirometry showed significantly higher forced vital capacity (FVC; p=0.0003) and no difference in forced expiratory volume in 1 second (FEV1; p=0.08) before work shift compared to expected values. FVC was 108,1 % and FEV1 was 104

Acute pesticide poisoning in developing countries is a considerable problem, requiring diagnosis and treatment. This study describes how training of health care workers in Uganda affects their ability to diagnose and manage acute pesticide poisoning. A postintervention cross-sectional study was conducted using a standardized questionnaire. A total of 326 health care workers in Uganda were interviewed on knowledge and handling of acute pesticide poisoning. Of those, 173 health care workers had received training, whereas 153 untrained health care workers from neighboring regions served as controls. Trained health care workers scored higher on knowledge of pesticide toxicity and handling of acute pesticide poisoning. Stratification by sex, profession, experience, and health center level did not have any influence on the outcome. Training health care workers can improve their knowledge and treatment of pesticide poisonings. Knowledge of the subject is still insufficient among health care workers and further training is needed.

Full Text Available To examine the independent contribution of individual, community and state-level factors to health care service utilization for children with acute childhood illnesses in Nigeria.The study was based on secondary analyses of cross-sectional population-based data from the 2013 Nigeria Demographic and Health Survey (DHS. Multilevel logistic regression models were applied to the data on 6,427 under-five children who used or did not use health care service when they were sick (level 1, nested within 896 communities (level 2 from 37 states (level 3.About one-quarter of the mothers were between 15 and 24 years old and almost half of them did not have formal education (47%. While only 30% of the children utilized health service when they were sick, close to 67% lived in the rural area. In the fully adjusted model, mothers with higher education attainment (Adjusted odds ratio [aOR] = 1.63; 95% credible interval [CrI] = 1.31-2.03, from rich households (aOR = 1.76; 95% CrI = 1.35-2.25, with access to media (radio, television or magazine (aOR = 1.18; 95% CrI = 1.08-1.29, and engaging in employment (aOR = 1.18; 95% CrI = 1.02-1.37 were significantly more likely to have used healthcare services for acute childhood illnesses. On the other hand, women who experienced difficulty getting to health facilities (aOR = 0.87; 95% CrI = 0.75-0.99 were less likely to have used health service for their children.Our findings highlight that utilization of healthcare service for acute childhood illnesses was influenced by not only maternal factors but also community-level factors, suggesting that public health strategies should recognise this complex web of individual composition and contextual composition factors to guide provision of healthcare services. Such interventions could include: increase in female school enrolment, provision of interest-free loans for small and medium scale enterprises, introduction of mobile clinics and establishment of more primary health care

Martin Marietta Energy Systems, Inc. (MMES), and Martin Marietta Utility Services, Inc. (MMUS), are engaged in phased programs to update the safety documentation for the existing US Department of Energy (DOE)-owned facilities. The safety analysis of potential toxic hazards requires a methodology for evaluating human health effects of predicted toxic exposures. This report provides a consistent set of health effects and documents toxicity estimates corresponding to these health effects for some of the more important chemicals found within MMES and MMUS. The estimates are based on published toxicity information and apply to acute exposures for an ``average`` individual. The health effects (toxicological endpoints) used in this report are (1) the detection threshold; (2) the no-observed adverse effect level; (3) the onset of irritation/reversible effects; (4) the onset of irreversible effects; and (5) a lethal exposure, defined to be the 50% lethal level. An irreversible effect is defined as a significant effect on a person`s quality of life, e.g., serious injury. Predicted consequences are evaluated on the basis of concentration and exposure time.

Research demonstrates that acute exercise can enhance retrospective episodic memory performance. However, limited research has examined the effects of acute exercise on prospective memory, and no studies have examined the effects of exercise on false memory performance. This study examined the potential effects of acute exercise on prospective memory and false memory performance. A between-group randomized controlled trial was employed, with participants (college students; M age  = 20 years) randomized into an exercise group (15-minute acute bout of treadmill walking; N = 25) or a control group (15 minutes of sitting; N = 26). Prospective memory was assessed from two laboratory and two naturalistic assessments outside the lab. False memory was assessed using a word-list trial. There were no statistically significant differences in prospective memory based on group allocation (F Group×Time  = 1.17; P = 0.32; η 2  = 0.06). However, the control group recalled more false words and had a higher rate of false memory recognition (F Group×Time  = 3.15; P = 0.01; η 2  = 0.26). These findings indicate that acute moderate-intensity aerobic exercise is not associated with prospective memory performance but provides some suggestive evidence that acute exercise may reduce the rate of false memories.

The effectiveness of psychological therapies for those receiving acute adult mental health inpatient care remains unclear, partly because of the difficulty in conducting randomized controlled trials (RCTs) in this setting. The aim of this meta-analysis was to synthesize evidence from all controlled trials of psychological therapy carried out with this group, to estimate its effects on a number of important outcomes and examine whether the presence of randomization and rater blinding moderated these estimates. A systematic review and meta-analysis of all controlled trials of psychological therapy delivered in acute inpatient settings was conducted, with a focus on psychotic symptoms, readmissions or emotional distress (anxiety and depression). Studies were identified through ASSIA, EMBASE, CINAHL, Cochrane, MEDLINE, and PsycINFO using a combination of the key terms 'inpatient', 'psychological therapy', and 'acute'. No restriction was placed on diagnosis. The moderating effect of the use of assessor-blind RCT methodology was examined via subgroup and sensitivity analyses. Overall, psychological therapy was associated with small-to-moderate improvements in psychotic symptoms at end of therapy but the effect was smaller and not significant at follow-up. Psychological therapy was also associated with reduced readmissions, depression, and anxiety. The use of single-blind randomized controlled trial methodology was associated with significantly reduced benefits on psychotic symptoms and was also associated with reduced benefits on readmission and depression; however, these reductions were not statistically significant. The provision of psychological therapy to acute psychiatric inpatients is associated with improvements; however, the use of single-blind RCT methodology was associated with reduced therapy-attributable improvements. Whether this is a consequence of increased internal validity or reduced external validity is unclear. Trials with both high internal and

There is evidence to suggest a role of emotions in placebo and nocebo effects, but whether acute psychological stress changes the magnitude of placebo or nocebo responses has not been tested. In a clinically relevant model of visceroception, we assessed effects of acute psychological stress on changes in urgency and pain in response to positive or negative treatment suggestions. In 120 healthy volunteers, perceived urge-to-defecate and pain in response to individually calibrated rectal distensions were measured with visual analogue scales during a BASELINE. Participants then underwent the Trier Social Stress Test (N = 60) or a simple cognitive task (control, N = 60) and were randomized to positive (placebo), negative (nocebo), or neutral treatment information regarding intravenous administration of saline. The series of distensions was repeated, and changes in visual analogue scales from BASELINE to TEST were compared between groups using analysis of covariance and planned post hoc tests. Treatment information emerged as a main factor (P effects for both urgency and pain. Effects for urgency were modulated by stress (interaction effect: P stressed groups. For pain, effects of stress emerged for nocebo responses, which were only evident in stressed groups (P = 0.009). This is the first experimental study supporting effects of acute psychological stress on placebo and nocebo responses in visceroception. Results call for mechanistic as well as patient studies to assess how psychological stress shapes patients' treatment expectations and thereby affects health outcomes.

Several epidemiological studies have reported an association between environmental pollution and various health conditions in individuals residing in industrial complexes. To evaluate the effects of pollution from industrial complex on human health, we performed a pooled analysis of environmental epidemiologic monitoring data for residents living near national industrial complexes in Korea. The respiratory and allergic symptoms and the prevalence of acute and chronic diseases, including cancer, were used as the outcome variables for health effects. Multiple logistic regression analysis was used to analyze the relationship between exposure to pollution from industrial complexes and health conditions. After adjusting for age, sex, smoking status, occupational exposure, level of education, and body mass index, the residents near the industrial complexes were found to have more respiratory symptoms, such as cough (odds ratio [OR], 1.18; 95% confidence interval [CI], 1.06 to 1.31) and sputum production (OR, 1.13; 95% CI, 1.03 to 1.24), and symptoms of atopic dermatitis (OR, 1.10; 95% CI, 1.01 to 1.20). Among residents of the industrial complexes, the prevalence of acute eye disorders was approximately 40% higher (OR, 1.39; 95% CI, 1.04 to 1.84) and the prevalence of lung and uterine cancer was 3.45 times and 1.88 times higher, respectively, than those among residents of the control area. This study showed that residents living in the vicinity of industrial complexes have a high risk of acute and chronic diseases including respiratory and allergic conditions. These results can be used as basic objective data for developing health management measures for individuals residing near industrial complexes.

The Nuclear Regulatory Commission (NRC) has sponsored several studies to identify and quantify, through the use of models, the potential health effects of accidental releases of radionuclides from nuclear power plants. The Reactor Safety Study provided the basis for most of the earlier estimates related to these health effects. Subsequent efforts by NRC-supported groups resulted in improved health effects models that were published in the report entitled open-quotes Health Effects Models for Nuclear Power Plant Consequence Analysisclose quotes, NUREG/CR-4214, 1985 and revised further in the 1989 report NUREG/CR-4214, Rev. 1, Part 2. The health effects models presented in the 1989 NUREG/CR-4214 report were developed for exposure to low-linear energy transfer (LET) (beta and gamma) radiation based on the best scientific information available at that time. Since the 1989 report was published, two addenda to that report have been prepared to (1) incorporate other scientific information related to low-LET health effects models and (2) extend the models to consider the possible health consequences of the addition of alpha-emitting radionuclides to the exposure source term. The first addendum report, entitled open-quotes Health Effects Models for Nuclear Power Plant Accident Consequence Analysis, Modifications of Models Resulting from Recent Reports on Health Effects of Ionizing Radiation, Low LET Radiation, Part 2: Scientific Bases for Health Effects Models,close quotes was published in 1991 as NUREG/CR-4214, Rev. 1, Part 2, Addendum 1. This second addendum addresses the possibility that some fraction of the accident source term from an operating nuclear power plant comprises alpha-emitting radionuclides. Consideration of chronic high-LET exposure from alpha radiation as well as acute and chronic exposure to low-LET beta and gamma radiations is a reasonable extension of the health effects model

Food intake and exercise have been shown to alter body satisfaction in a state-dependent manner. One-time consumption of food perceived as unhealthy can be detrimental to body satisfaction, whereas an acute bout of moderate-intensity aerobic exercise can be beneficial. The current study examined the effect of exercise on state body image and appearance-related self-esteem following consumption of isocaloric foods perceived as healthy or unhealthy in 36 female college students (18-30 years old) in the Northeastern United States. Using a randomized-controlled design, participants attended six study sessions with breakfast conditions (healthy, unhealthy, no food) and activity (exercise, quiet rest) as within-participants factors. Body image questionnaires were completed prior to breakfast condition, between breakfast and activity conditions, and following activity condition. Results showed that consumption of an unhealthy breakfast decreased appearance self-esteem and increased body size perception, whereas consumption of a healthy breakfast did not influence appearance self-esteem but increased body size perception. Exercise did not influence state body image attitudes or perceptions following meal consumption. Study findings suggest that morning meal type, but not aerobic exercise, influence body satisfaction in college-aged females. Copyright © 2018. Published by Elsevier Ltd.

Acute diarrhea continues to be a leading cause of morbidity, hospitalization and mortality worldwide and probiotics have been proposed as a complementary therapy in the treatment of acute diarrhea. Regarding the treatment of acute diarrhea, a few probiotics including Saccharomyces boulardii seem to be promising therapeutic agents. We performed a systematic review and meta-analysis regarding the use of S. boulardii in the treatment of acute infectious diarrhea with relevant studies that searched with the PubMed, Embase, Scopus, Google Scholar, the Cochrane Controlled Trials Library, and the Cochrane Database of Systematic Reviews through October 2011. This review describes the effects of S. boulardii on the duration of diarrhea, the risk of diarrhea during the treatment (especially at the third day) and duration of hospitalization in patients with acute infectious diarrhea. This review also focused on the potential effects of S. boulardii for acute infectious diarrhea due to different etiological causes. S. boulardii significantly reduced the duration of diarrhea approximately 24 h and that of hospitalization approximately 20 h. S. boulardii shortened the initial phase of watery stools; mean number of stools started to decrease at day 2; moreover, a significant reduction was reported at days 3 and 4. This systematic review and meta-analysis of the efficacy of S. boulardii in the treatment of acute infectious diarrhea show that there is strong evidence that this probiotic has a clinically significant benefit, whatever the cause, including in developing countries. Therefore, with S. boulardii, the shortened duration of diarrhea and the reduction in hospital stay result in social and economic benefits.

Marijuana produces acute increases in positive subjective effects and decreased reactivity to negative affective stimuli, though may also acutely induce anxiety. Implicit attentional and evaluative processes may explicate marijuana’s ability to acutely increase positive and negative emotions. This within-subjects study examined whether smoked marijuana with 2.7–3.0 % delta-9-tetrahydrocannabinol (THC), relative to placebo, acutely changed attentional processing of rewarding and negative affec...

The economic costs of radiation-induced health effects: Estimation and simulation

International Nuclear Information System (INIS)

Nieves, L.A.; Tawil, J.J.

1988-08-01

This effort improves the quantitative information available for use in evaluating actions that alter health risks due to population exposure to ionizing radiation. To project the potential future costs of changes in health effects risks, Pacific Northwest Laboratory (PNL) constructed a probabilistic computer model, Health Effects Costs Model (HECOM), which utilizes the health effect incidence estimates from accident consequences models to calculate the discounted sum of the economic costs associated with population exposure to ionizing radiation. Application of HECOM to value-impact and environmental impact analyses should greatly increase the quality of the information available for regulatory decision making. Three major types of health effects present risks for any population sustaining a significant radiation exposure: acute radiation injuries (and fatalities), latent cancers, and impairments due to genetic effects. The literature pertaining to both incidence and treatment of these health effects was reviewed by PNL and provided the basis for developing economic cost estimates. The economic costs of health effects estimated by HECOM represent both the value of resources consumed in diagnosing, treating, and caring for the patient and the value of goods not produced because of illness or premature death due to the health effect. Additional costs to society, such as pain and suffering, are not included in the PNL economic cost measures since they do not divert resources from other uses, are difficult to quantify, and do not have a value observable in the marketplace. 83 refs., 3 figs., 19 tabs

The influence of source term release parameters on health effects

International Nuclear Information System (INIS)

Jeong, Jong Tae; Ha, Jae Joo

1998-08-01

In this study, the influence of source term release parameters on the health effects was examined. This is very useful in identifying the relative importance of release parameters and can be an important factor in developing a strategy for reducing offsite risks. The release parameters investigated in this study are release height, heat content, fuel burnup, release time, release duration, and warning time. The health effects affected by the change of release parameters are early fatalities, cancer fatalities, early injuries, cancer injuries, early fatality risk, population weighted early fatality risk, population weighted cancer fatality risk, effective whole body population dose, population exceeding an early acute red bone marrow dose of 1.5 Sv, and distance at which early fatalities are expected to occur. As release height increases, the values of early health effects such as early fatalities and injuries decrease. However, the release height dose not have significant influences on late health effects. The values of both early and late health effects decrease as heat content increases. The increase fuel burnup, i.e., the increase of core inventories increases the late health effects, however, has small influence on the early health effects. But, the number of early injuries increases as the fuel burnup increases. The effects of release time increase shows very similar influence on both the early and late health effects. As the release time increases to 2 hours, the values of health effects increase and then decrease rapidly. As release duration increases, the values of late health effects increase slightly, however, the values of early health effects decrease. As warning time increases to 2 hours, the values of late health effects decrease and then shows no variation. The number of early injuries decreases rapidly as the warning time increases to 2 hours. However, the number of early fatalities and the early fatality risk increase as the warning time increases

The mTOR inhibitor rapamycin has limited acute anticonvulsant effects in mice.

Directory of Open Access Journals (Sweden)

Adam L Hartman

Full Text Available The mammalian target of rapamycin (mTOR pathway integrates signals from different nutrient sources, including amino acids and glucose. Compounds that inhibit mTOR kinase activity such as rapamycin and everolimus can suppress seizures in some chronic animal models and in patients with tuberous sclerosis. However, it is not known whether mTOR inhibitors exert acute anticonvulsant effects in addition to their longer term antiepileptogenic effects. To gain insights into how rapamycin suppresses seizures, we investigated the anticonvulsant activity of rapamycin using acute seizure tests in mice.Following intraperitoneal injection of rapamycin, normal four-week-old male NIH Swiss mice were evaluated for susceptibility to a battery of acute seizure tests similar to those currently used to screen potential therapeutics by the US NIH Anticonvulsant Screening Program. To assess the short term effects of rapamycin, mice were seizure tested in ≤ 6 hours of a single dose of rapamycin, and for longer term effects of rapamycin, mice were tested after 3 or more daily doses of rapamycin.The only seizure test where short-term rapamycin treatment protected mice was against tonic hindlimb extension in the MES threshold test, though this protection waned with longer rapamycin treatment. Longer term rapamycin treatment protected against kainic acid-induced seizure activity, but only at late times after seizure onset. Rapamycin was not protective in the 6 Hz or PTZ seizure tests after short or longer rapamycin treatment times. In contrast to other metabolism-based therapies that protect in acute seizure tests, rapamycin has limited acute anticonvulsant effects in normal mice.The efficacy of rapamycin as an acute anticonvulsant agent may be limited. Furthermore, the combined pattern of acute seizure test results places rapamycin in a third category distinct from both fasting and the ketogenic diet, and which is more similar to drugs acting on sodium channels.

It was reported that the tiron had good therapeutic effects on small animals with acute uranium intoxication. The tiron's therapeutic effects as a first aid on large animals (38 dogs) with acute uranium poisoning are reported in this paper. Indices reflecting its effect were as follows: excretion rate of uranium from the dogs, several appropriate biochemical tests, clinical manifestations, histo-pathological changes of kidney and liver, and also the mortality of dogs. The results showed that the tiron or a combination of tiron and NaHCO 3 has a good therapeutic effect as a first aid on the dogs receiving lethal dose of uranyl nitrate

to review and evaluate the recent literature on the health effects of exposure to mobile phone base station (MPBS) radiation. we performed a systematic review of randomized human trials conducted in laboratory settings and of epidemiological studies that investigated the health effects of MPBS radiation in the everyday environment. we included in the analysis 17 articles that met our basic quality criteria: 5 randomized human laboratory trials and 12 epidemiological studies. The majority of the papers (14) examined self-reported non-specific symptoms of ill-health. Most of the randomized trials did not detect any association between MPBS radiation and the development of acute symptoms during or shortly after exposure. The sporadically observed associations did not show a consistent pattern with regard to symptoms or types of exposure. We also found that the more sophisticated the exposure assessment, the less likely it was that an effect would be reported. Studies on health effects other than non-specific symptoms and studies on MPBS exposure in children were scarce. the evidence for a missing relationship between MPBS exposure up to 10 volts per metre and acute symptom development can be considered strong because it is based on randomized, blinded human laboratory trials. At present, there is insufficient data to draw firm conclusions about health effects from long-term low-level exposure typically occurring in the everyday environment.

The risk assessment of residues of veterinary drugs in food is a field that continues to evolve. The toxicological end-points to be considered are becoming more nuanced and in light of growing concern about the development of antimicrobial resistance, detailed analysis of the antimicrobial activity of the residues of veterinary drugs in food is increasingly incorporated in the assessment. In recent years, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) has refined its approaches to provide a more comprehensive and fit-for-purpose risk assessment. This publication describes in detail the consideration of acute and chronic effects, the estimation of acute and chronic dietary exposure, current approaches for including microbiological endpoints in the risk assessment, and JECFA's considerations for the potential effects of food processing on residues from veterinary drugs. JECFA now applies these approaches in the development of health-based guidance values (i.e. safe exposure levels) for residues of veterinary drugs. JECFA, thus, comprehensively addresses acute and chronic risks by using corresponding estimates for acute and chronic exposure and suitable correction for the limited bioavailability of bound residues by the Gallo-Torres model. On a case-by-case basis, JECFA also considers degradation products that occur from normal food processing of food containing veterinary drug residues. These approaches will continue to be refined to ensure the most scientifically sound basis for the establishment of health-based guidance values for veterinary drug residues.

Nursing is an emotionally demanding profession and deficiencies in nurses' mental wellbeing, characterised by low vitality and common mental disorders, have been linked to low productivity, absenteeism and presenteeism. Part of a larger study of nurses' health, the aim of this paper was to describe the mental health status and related characteristics of nurses working in two acute metropolitan teaching hospitals. A cross sectional survey design was used. The Registered and Enrolled Nurse workforce, employed on any form of contract, at two teaching hospitals in Sydney Australia were invited to participate. The survey tool was compiled of validated tools and questions. Family and medical history and health risk-related characteristics, current psycho-active medications, smoking status, alcohol intake, eating disorders, self-perceived general health, mental health and vitality, demographic, social and occupational details were collected. A total of 1215 surveys were distributed with a usable response rate of 382 (31.4%). Altogether 53 nurses (14%) reported a history of mental health disorders, of which n = 49 (13%) listed diagnoses of anxiety and/or depression; 22 (6%) were currently taking psychoactive medication. Symptoms that could potentially indicate a mental health issue were more common, with 248 (65.1%) reporting they had experienced symptoms sometimes or often in the last 12 month. Nurses had better mental health if they had better general health, lived with a spouse/ partner rather than alone, had fewer symptoms, sleep problems or disordered eating behaviours, were not an informal carer and did not work nights. Nurses had greater vitality if they were male, had better general health, fewer sleep problems or symptoms generally and lived with a spouse/ partner rather than alone; less vitality if they were an informal carer or had disordered eating. Nurses and their managers should strive to create workplaces where working practices promote nurses' health

The Acute Psychological Trauma (APT) Study was a collaboration between an acute care hospital, a specialized multidisciplinary program designed to meet the mental health needs of injured workers, and a large urban public transit system. The overall purpose was to evaluate a Best Practices Intervention (BPI) for employees affected by acute psychological trauma compared to a Treatment as Usual (TAU) group. The specific purpose is to discuss facilitators and barriers that were recognized in implementing and carrying out mental health research in a workplace setting. Over the course of the APT study, a joint implementation committee was responsible for day-to-day study operations and made regular observations on the facilitators and barriers that arose throughout the study. The facilitators to this study included the longstanding relationships among the partners, increased recognition for the need of mental health research in the workplace, and the existence of a community advisory committee. The significant barriers to doing this study of mental health research in the workplace included differences in organizational culture, inconsistent union support, co-interventions, and stigma. Researchers and funding agencies need to be flexible and provide additional resources in order to overcome the barriers that can exist doing workplace mental health research.

To synthesize and appraise research testing the effects of exercise interventions on fitness, cardiometabolic health, and bone health among adults with spinal cord injury (SCI). Electronic databases were searched (1980-2016). Included studies employed exercise interventions for a period ≥2 weeks, involved adults with acute or chronic SCI, and measured fitness (cardiorespiratory fitness, power output, or muscle strength), cardiometabolic health (body composition or cardiovascular risk factors), or bone health outcomes. Evidence was synthesized and appraised using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). A total of 211 studies met the inclusion criteria (22 acute, 189 chronic). For chronic SCI, GRADE confidence ratings were moderate to high for evidence showing exercise can improve all of the reviewed outcomes except bone health. For acute SCI, GRADE ratings were very low for all outcomes. For chronic SCI, there was low to moderate confidence in the evidence showing that 2-3 sessions/week of upper body aerobic exercise at a moderate to vigorous intensity for 20-40 minutes, plus upper body strength exercise (3 sets of 10 repetitions at 50%-80% 1-repetition maximum for all large muscle groups), can improve cardiorespiratory fitness, power output, and muscle strength. For chronic SCI, there was low to moderate confidence in the evidence showing that 3-5 sessions per week of upper body aerobic exercise at a moderate to vigorous intensity for 20-44 minutes can improve cardiorespiratory fitness, muscle strength, body composition, and cardiovascular risk. Exercise improves fitness and cardiometabolic health of adults with chronic SCI. The evidence on effective exercise types, frequencies, intensities, and durations should be used to formulate exercise guidelines for adults with SCI. © 2017 American Academy of Neurology.

To show certain health effects associated with acute and chronic exposure to nitrous oxide of staff of the Department of Anaesthesiology and Intensive Care at the Clinical Hospital in Shtip. A transversal study was conducted, that include 43 health workers (23 - exposed and 20 - unexposed). Personal exposure to nitrous oxide for this group members was assessed through continuous measurement over 8 hours shift within breathing zone of the subjects involved, using handheld electrochemical instrument with datalogging option direct. In order to determine presence of possible health effects associated with acute and chronic exposure to nitrous oxide in ORs and ICUs, a specially designed questionnaire was prepared and distributed to be anonymously filled out, by all the examinees from both examined groups. Data were statistically tested for normality and also quantitative and qualitative assessment was performed. From the results obtained, a significant difference in several health effects between exposed and unexposed groups can be noted, including headaches, dizziness, nausea and vomiting, euphoria and tachycardia. Regarding the excitement, the appearance of depression, the feeling of numbness and tingling of the hands and feet, the differences between the two examined groups were not significant. It can be concluded that chronic exposure to nitrous oxide is associated with the adverse health effects.

Full Text Available Background Acute inflammatory pain causes by direct stimulation of nociceptors and release of inflammatory mediators and cytokines. Probiotics are capable to modulate the immune system, down regulate the inflammatory mediators, and increase regulatory and anti-inflammatory cytokines. Objectives The aim of this study was to examine the effect of oral administration of probiotics on behavioral, cellular and molecular aspects of acute inflammatory pain in male rats. Methods Adult male Wistar rats (200 - 220 g were selected and randomly divided into 7 experimental groups (CFA, CFA control, CFA + vehicle (distilled water, CFA + 3 doses of probiotics, CFA + indomethacin and each group was divided into 3 subgroups based on different time points (days 0, 3, and 7 (n = 6 rats, each group. Complete Freund’s adjuvant (CFA-induced arthritis (AA was caused by a single subcutaneous injection of CFA into the rats’ left hind paw on day 0. Different doses of probiotics (1/250, 1/500 and 1/1000 (109 CFU/g was administered daily (gavage after the CFA injection. Blood samples were taken from the vessel retro-orbital corners of rat’s eyes. After behavioral and inflammatory tests, the lumbar segments of rat’s spinal cord (L1 - L5 were removed. Hyperalgesia, edema, serum TNF-α and IL-1β levels and NF-κB expression were assessed on days 0, 3, and 7 of the study. Results The results of this study showed the role of effective dose of probiotics (1/500 in reducing edema (P = 0.0009, hyperalgesia (P = 0.0002, serum levels of TNF-α (P = 0.0004 and IL-1β (P = 0.0004 and NF-κB expression (P = 0.0007 during the acute phase of inflammatory pain caused by CFA. Conclusions It seems that an effective dose of probiotics due to its direct effects on inhibition of intracellular signaling pathways and pro-inflammatory cytokines can alleviate inflammatory symptoms and pain in the acute phase.

So, you want to design an acute mental health inpatient unit: physical issues for consideration.

The aim of this paper is to explore important considerations when planning an acute mental health inpatient unit. Planning a mental health acute inpatient facility should be about more than just building a beautiful, fabulous facility. A novel architectural design, fancy gadgets, safe tapware, new lounge suites, good light and air circulation are all incredibly important and good architects and designers can inform us about new developments in architecture and design that we must incorporate in our design plans. However, to design a facility that is right for tomorrow, it is also important to spend time trying to understand what happens in the facility and how the new facility is going to make things different and better. Planning of a health facility should be about creating an environment that is not only pleasant, comfortable and safe but also one that would enable and facilitate better care. It is important to map processes before rather than after building a facility, so that this process mapping can inform design and we do not keep falling into the trap of building a beautiful new facility but losing the opportunity to make care better.

The literature of acute exacerbation of chronic obstructive pulmonary disease (COPD) is fast expanding. This review focuses on several aspects of acute exacerbation of COPD (AECOPD) including epidemiology, diagnosis and management. COPD poses a major health and economic burden in the Asia-Pacific region, as it does worldwide. Triggering factors of AECOPD include infectious (bacteria and viruses) and environmental (air pollution and meteorological effect) factors. Disruption in the dynamic balance between the 'pathogens' (viral and bacterial) and the normal bacterial communities that constitute the lung microbiome likely contributes to the risk of exacerbations. The diagnostic approach to AECOPD varies based on the clinical setting and severity of the exacerbation. After history and examination, a number of investigations may be useful, including oximetry, sputum culture, chest X-ray and blood tests for inflammatory markers. Arterial blood gases should be considered in severe exacerbations, to characterize respiratory failure. Depending on the severity, the acute management of AECOPD involves use of bronchodilators, steroids, antibiotics, oxygen and noninvasive ventilation. Hospitalization may be required, for severe exacerbations. Nonpharmacological interventions including disease-specific self-management, pulmonary rehabilitation, early medical follow-up, home visits by respiratory health workers, integrated programmes and telehealth-assisted hospital at home have been studied during hospitalization and shortly after discharge in patients who have had a recent AECOPD. Pharmacological approaches to reducing risk of future exacerbations include long-acting bronchodilators, inhaled steroids, mucolytics, vaccinations and long-term macrolides. Further studies are needed to assess the cost-effectiveness of these interventions in preventing COPD exacerbations. © 2016 Asian Pacific Society of Respirology.

Stress ulcer is one ofacute stroke complications. Giving ranitidine or omeprazole may prevent stress ulcer, but may increase the occurrence of pneumonia. Thus, it will affect the outcome of acute stroke. The method was experimental with a randomized control-group pretest - posttest design. This study divided the subjects into two groups, ranitidine 300mg and omeprazole 20mg group.We observed the patients whether stress ulcer or pneumonia occurred during hospitalization. Then, we measured the outcome by the National Institutes of Health Stroke Scaleand modified Rankin Scale. There were 32 subjects in this study. Only 1 (3.1%) subject suffered stress ulcer, and 3 (3.1%) suffered pneumonia in ranitidine group. Moreover, 2 (6.2%) subjects suffered pneumonia in omeprazole group. The differences were not significant between the two groups (p = 0.31 and p = 0.54). There was no significant effect and difference effect on the administration of both medications to the outcome at day 14. These results indicate that ranitidine and omeprazole have anequal effectiveness in the prevention of stress ulcer and also have equal effect on the occurrence of pneumonia, and both have no effect on the outcome of acute stroke patients.

People diagnosed with borderline personality disorder (BPD) are highly prevalent in acute mental health wards, with staff nurses identifying a challenge in working with people who can be significantly distressed. This has contributed to a negative stereotype verging on stigmatization. Mentalization-based therapy (MBT) is a psychological therapy which has been shown to be of benefit to people with a diagnosis of BPD, yet it has been utilized and evaluated only in partial hospitalization and outpatient settings. Despite this, most people diagnosed with BPD will continue to be treated in generic inpatient settings such as acute mental health. Mentalization-based therapy skills training (MBT-S) is a new and cost-effective 2-day workshop aiming to provide generalist practitioners with MBT skills for use in generic settings. This study aimed to capture staff perceptions of the impact of MBT-S on their practice when working with people with a diagnosis of BPD in acute mental health. Through two focus groups, this study assessed the perceptions of nine staff nurses. An interpretive phenomenological approach was utilized in data analysis. Participants found the approach easy to grasp, improving of consistency between staff and flexible in its use in planned or 'off the cuff' discussions. MBT-S promoted empathy and humane responses to self-harm, impacted on participants ability to tolerate risk and went some way to turning the negative perception of BPD through changing the notion of patients as 'deliberately difficult'. Staff felt empowered and more confident in working with people with a diagnosis of BPD. The positive implication for practice was the ease in which the approach was adopted and participants perception of MBT-S as an empowering skill set which also contributed to attitudinal change. In acute mental health environments, which may not have the resources to provide long-term structured treatments to patients, MBT-S could be viewed as ideal as participants

High-intensity interval training (HIIT) interventions improve cardiovascular health, yet the acute effects on circulating and functional biomarkers of cardiovascular function are unclear in individuals with type 2 diabetes (T2D). To explore this, we conducted two investigations to examine the acute response to HIIT in individuals with T2D. Study 1 measured blood pressure, endothelial-dependent dilation, circulating measures of endothelial activation, and troponin T, 30 min and 2 h after HIIT (7 × 1-min intervals) in T2D (n = 8) and age-matched normoglycemic controls (CTL; n = 8). Study 2 assessed circulating measures of endothelial activation and troponin T, 30 min, and 24 h after HIIT (10 × 1-min intervals) in ten previously trained T2D men. In study 1, markers of endothelial function and activation within the first 2 h after HIIT did not differ from baseline between T2D and CTL participants, except at 30 min after HIIT for glucose, which was reduced more in T2D than CTL (by -0.8 ± 1.2 mmol/L, p = 0.04), and VCAM-1, which was reduced more 30 min after HIIT in CTL compared to T2D (by -187 ± 221 ng/mL, p = 0.05). Study 2 saw no significant difference in any circulating markers of endothelial activation and troponin T, 30 min, and 24 h after HIIT in trained T2D males. Exploratory findings from these two studies suggest that acute HIIT does not substantially alter circulating and functional markers of cardio(vascular) health in individuals with T2D who are unaccustomed (study 1) and accustomed to HIIT (study 2).

Psychiatric acute units use different levels of segregation to satisfy needs for containment and decrease in sensory input for behaviourally disturbed patients. Controlled studies evaluating the effects of the procedure are lacking. The aim of the present study was to compare effects in acutely admitted patients with the use of a psychiatric intensive care unit (PICU) and not in a psychiatric acute department. In a naturalistic study, one group of consecutively referred patients had access only to the PICU, the other group to the whole acute unit. Data were obtained for 56 and 62 patients using several scales. There were significant differences in reduction of behaviour associated with imminent, threatening incidents (Broset Violence Checklist), and actual number of such incidents (Staff Observation Aggression Scale-Revised) in favour of the group that was treated in a PICU. The principles of patient segregation in PICUs have favourable effects on behaviours associated with and the actual numbers of violent and threatening incidents.

Acute malnutrition affects millions of children each year, yet global coverage of life-saving treatment through the community-based management of acute malnutrition (CMAM) is estimated to be below 15%. We investigated the potential role of stigma as a barrier to accessing CMAM. We surveyed caregivers bringing children to rural health facilities in Marsabit County, Kenya, divided into three strata based on the mid-upper arm circumference of the child: normal status (n = 327), moderate acute malnutrition (MAM, n = 241) and severe acute malnutrition (SAM, n = 143). We used multilevel mixed effects logistic regression to estimate the odds of reporting shame as a barrier to accessing health care. We found that the most common barriers to accessing child health care were those known to be universally problematic: women's time and labour constraints. These constituted the top five most frequently reported barriers regardless of child acute malnutrition status. In contrast, the odds of reporting shame as a barrier were 3.64 (confidence interval: 1.66-8.03, P stigma is an under-recognized barrier to accessing CMAM and may constrain programme coverage. In light of the large gap in coverage of CMAM, there is an urgent need to understand the sources of acute malnutrition-associated stigma and adopt effective means of de-stigmatization. © 2015 John Wiley & Sons Ltd.

Full Text Available Background. Acute bronchiolitis infection during infancy is associated with an increased risk of asthma later in life. The objective of this study was to determine if inhaled steroids are effective in preventing the development of recurrent wheeze or asthma following acute bronchiolitis. Methods. Multiple databases and bibliographies of selected references were searched. Inclusion required (a a randomized controlled trial of inhaled steroids and control group, (b at least 2 weeks duration of therapy started during the acute phase of disease, and (c identification of the rate of recurrent wheeze or asthma at least 6 months after therapy. Results. Of 1410 studies reviewed, 8 reports were included in this meta-analysis (748 patients. The overall odds ratio for developing recurrent wheeze or asthma with treatment versus without treatment was 1.02 (95% confidence interval = 0.58-1.81. Conclusions. A course of inhaled steroids after acute bronchiolitis is not effective in preventing recurrent wheeze or asthma.

Many countries now have national mental health policies and guidelines to decrease or eliminate the use of seclusion and restraint yet the use of Pro Re Nata (PRN) medications has received less practice evaluation. This research aimed to identify mental health nurses' attitudes towards the use of PRN medications with mental health consumers. Participants were working in forensic mental health and non-forensic acute mental health settings. The "Attitudes towards PRN medication use survey" was used and data were collected online. Data were analysed using the Statistical Package Social Sciences, Version 22.0. Practice differences between forensic and other acute mental health settings were identified related to the use of PRN medications to manage symptoms from nicotine, alcohol and other drug withdrawal. Differences related to the useage of comfort rooms and conducting comprehensive assessments of consumers' psychiatric symptoms were also detected. Qualitative findings highlighted the need for increased accountability for the prescribing and administration of PRN medications along with more nursing education/training to use alternative first line interventions. Nurses administering PRN medications should be vigilant regarding the indications for this practice to ensure they are facilitating the consumer's recovery by reducing the use of all forms of potentially restrictive practices in the hospital setting. The reasons for using PRN medications and PRN administration rates must be continually monitored to avoid practices such as high dose antipsychotics use and antipsychotic polypharmacy to ensure the efficacy of the consumers' management plans on their health care outcomes. © 2017 Australian College of Mental Health Nurses Inc.

Our aim was to investigate the acute and 24-hour (h) effects of high-intensity interval training (HIIT) and moderate continuous training (MCT) on arterial pulse wave reflection, an established marker of arterial stiffness and cardiovascular risk. In a randomized cross-over design, 21 young healthy male participants performed a HIIT or a MCT on separate visits. Before and 5 (t5), 20 (t20), 35 (t35), and 50 (t50) minutes after the acute exercise bouts, the crude augmentation index (AIx) and the AIx at a set heart rate (AIx@75) were analysed by applanation tonometry. Starting 1 h post-exercise, both indices were captured over 24-h with an oscillometric monitoring device. AIx did not change significantly after MCT but declined progressively after HIIT, reaching significantly lower values compared to MCT at t35 (P = 0.045) and t50 (P = 0.008). AIx@75 increased after both acute exercise types but was higher after HIIT at t5 (P HIIT (P = 0.007) but not after MCT (P = 0.813). Exercise intensity affects pulse wave reflection, with different time courses for AIx and AIx@75 post-exercise. Although initially higher after HIIT, AIx@75 declines in the 24-h recovery period indicating more favourable effects on pulse wave reflection compared to MCT. This may result in substantial positive chronic training effects on arterial stiffness in health and cardiovascular disease. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Acute malnutrition is linked to child mortality and morbidity. Community-Based Management of Acute Malnutrition (CMAM) programs can be instrumental in large-scale detection and treatment of undernutrition. The World Health Organization (WHO) 2006 weight-for-height/length tables are diagnostic tools available to screen for acute malnutrition. Frontline workers (FWs) in a CMAM program in Dharavi, Mumbai, were using CommCare, a mobile application, for monitoring and case management of children in combination with the paper-based WHO simplified tables. A strategy was undertaken to digitize the WHO tables into the CommCare application. To measure differences in diagnostic accuracy in community-based screening for acute malnutrition, by FWs, using a mobile-based solution. Twenty-seven FWs initially used the paper-based tables and then switched to an updated mobile application that included a nutritional grade calculator. Human error rates specifically associated with grade classification were calculated by comparison of the grade assigned by the FW to the grade each child should have received based on the same WHO tables. Cohen kappa coefficient, sensitivity and specificity rates were also calculated and compared for paper-based grade assignments and calculator grade assignments. Comparing FWs (N = 14) who completed at least 40 screenings without and 40 with the calculator, the error rates were 5.5% and 0.7%, respectively (p .90), from .79 to .97, after switching to the mobile calculator. Sensitivity and specificity also improved significantly. The mobile calculator significantly reduces an important component of human error in using the WHO tables to assess acute malnutrition at the community level. © The Author(s) 2016.

Konetzka, R Tamara; Stuart, Elizabeth A; Werner, Rachel M

2018-02-07

In this paper we examine empirically the effect of integration on Medicare payment and rehospitalization. We use 2005-2013 data on Medicare beneficiaries receiving post-acute care (PAC) in the U.S. to examine integration between hospitals and the two most common post-acute care settings: skilled nursing facilities (SNFs) and home health agencies (HHA), using two measures of integration-formal vertical integration and informal integration representing preferential relationships between providers without formal relationships. Our identification strategy is twofold. First, we use longitudinal models with a fixed effect for each hospital-PAC pair in a market to test how changes in integration impact patient outcomes. Second, we use an instrumental variable approach to account for patient selection into integrated providers. We find that vertical integration between hospitals and SNFs increases Medicare payments and reduces rehospitalization rates. However, vertical integration between hospitals and HHAs has little effect, nor does informal integration between hospitals and either PAC setting. Copyright © 2018 The Author(s).

It may be used for patients who have infections that require parenteral treatment but who are otherwise stable enough to not require admission as inpatients. Objective: We aimed to review the treatment of patients with acute tonsillopharyngitis at the OPAT health care clinic in the Bahrain Defense Force Royal Medical Services (BDF-RMS, with regard to efficacy, patient satisfaction, cost effectiveness, and safety. Methods: A retrospective case notes review was conducted for all patients admitted to the OPAT clinic in the BDF-RMS with acute tonsillopharyngitis treated with ceftriaxone, between March 2012 and March 2014. Results: In the period between March 2012 and March 2014, 97 patients with acute tonsillopharyngitis were treated with ceftriaxone for a minimum of 3 days at the OPAT clinic. In total, 94.8% of patients completed the prescribed course of ceftriaxone. Total cure was achieved in 89.7% of patients. Usage of the OPAT clinic led to cost savings of 10,693 BD, while total bed days saved were 301 over the 2-year period examined by this study. Participants in the program expressed high satisfaction rates, and the average (± standard deviation score on a patient satisfaction survey was 4.41 (± 0.31 out of a total of 5. This study highlights the efficacy, patient satisfaction, cost effectiveness, and safety of the OPAT clinic service for the treatment of acute tonsillopharyngitis with ceftriaxone.

Hazardous substances can be released into the atmosphere due to industrial and transportation accidents, fires, tornadoes, earthquakes, and terrorists, thereby exposing workers and the nearby public to potential adverse health effects. Various enforceable guidelines have been set by regulatory agencies for worker and ambient air quality. However, these exposure levels generally are not applicable to rare lifetime acute exposures, which possibly could occur at high concentrations. Acute exposure guideline levels (AEGLs) provide estimates of concentrations for airborne exposures for an array of short durations that possibly could cause mild (AEGL-1), severe, irreversible, potentially disabling adverse health effects (AEGL-2), or life threatening effects (AEGL-3). These levels can be useful for emergency responders and planners in reducing or eliminating potential risks to the public. Procedures and methodologies for deriving AEGLs are reviewed in this paper that have been developed in the United States, with direct input from international representatives of OECD member-countries, by the National Advisory Committee for Acute Exposure Guidelines for Hazardous Substances and reviewed by the National Research Council. Techniques are discussed for the extrapolation of effects across different exposure durations. AEGLs provide a viable approach for assisting in the prevention, planning, and response to acute airborne exposures to toxic agents.

Physical forces have been widely used to stimulate bone growth in fracture repair. Addition of bone growth stimulation to the conservative treatment regime is more costly than standard health care. However, it might lead to cost-savings due to a reduction of the total amount of working days lost. This economic evaluation was performed to assess the cost-effectiveness of Pulsed Electromagnetic Fields (PEMF) compared to standard health care in the treatment of acute scaphoid fractures. An economic evaluation was carried out from a societal perspective, alongside a double-blind, randomized, placebo-controlled, multicenter trial involving five centres in The Netherlands. One hundred and two patients with a clinically and radiographically proven fracture of the scaphoid were included in the study and randomly allocated to either active bone growth stimulation or standard health care, using a placebo. All costs (medical costs and costs due to productivity loss) were measured during one year follow up. Functional outcome and general health related quality of life were assessed by the EuroQol-5D and PRWHE (patient rated wrist and hand evaluation) questionnaires. Utility scores were derived from the EuroQol-5D. The average total number of working days lost was lower in the active PEMF group (9.82 days) compared to the placebo group (12.91 days) (p = 0.651). Total medical costs of the intervention group (€1594) were significantly higher compared to the standard health care (€875). The total amount of mean QALY's (quality-adjusted life year) for the active PEMF group was 0.84 and 0.85 for the control group. The cost-effectiveness plane shows that the majority of all cost-effectiveness ratios fall into the quadrant where PEMF is not only less effective in terms of QALY's but also more costly. This study demonstrates that the desired effects in terms of cost-effectiveness are not met. When comparing the effects of PEMF to standard health care in terms of QALY's, PEMF

Full Text Available The Canadian Collaborative Acute Pain Initiative, established in 2002, is a voluntary, multidisciplinary consortium of acute pain health professionals from across Canada whose goal is to improve acute pain management through discussion and consensus. The group met in January 2002 to define strategic areas related to the treatment of acute pain. The areas identified were: the definition of pain; the epidemiology of pain; the concept of an 'ideal' acute pain management service; education; therapeutic options; symptom management; and research and safety. In November 2002, a second meeting was held to develop objectives and recommendations for the management of acute pain based on the defined areas. The outcome of these discussions is summarized in this paper.

Environmental and health effects of the herbicide glyphosate.

The herbicide glyphosate, N-(phosphonomethyl) glycine, has been used extensively in the past 40years, under the assumption that side effects were minimal. However, in recent years, concerns have increased worldwide about the potential wide ranging direct and indirect health effects of the large scale use of glyphosate. In 2015, the World Health Organization reclassified glyphosate as probably carcinogenic to humans. A detailed overview is given of the scientific literature on the movement and residues of glyphosate and its breakdown product aminomethyl phosphonic acid (AMPA) in soil and water, their toxicity to macro- and microorganisms, their effects on microbial compositions and potential indirect effects on plant, animal and human health. Although the acute toxic effects of glyphosate and AMPA on mammals are low, there are animal data raising the possibility of health effects associated with chronic, ultra-low doses related to accumulation of these compounds in the environment. Intensive glyphosate use has led to the selection of glyphosate-resistant weeds and microorganisms. Shifts in microbial compositions due to selective pressure by glyphosate may have contributed to the proliferation of plant and animal pathogens. Research on a link between glyphosate and antibiotic resistance is still scarce but we hypothesize that the selection pressure for glyphosate-resistance in bacteria could lead to shifts in microbiome composition and increases in antibiotic resistance to clinically important antimicrobial agents. We recommend interdisciplinary research on the associations between low level chronic glyphosate exposure, distortions in microbial communities, expansion of antibiotic resistance and the emergence of animal, human and plant diseases. Independent research is needed to revisit the tolerance thresholds for glyphosate residues in water, food and animal feed taking all possible health risks into account. Copyright © 2017 Elsevier B.V.

2012-07-01

A major solar particle event (SPE) may place astronauts at significant risk for the acute radiation syndrome (ARS), which may be exacerbated when combined with other space flight stressors, such that the mission or crew health may be compromised. The National Space Biomedical Research Institute (NSBRI) Center of Acute Radiation Research (CARR) is focused on the assessment of risks of adverse biological effects related to the ARS in animal models exposed to space flight stressors combined with the types of radiation expected during an SPE. As part of this program, FDA-approved drugs that may prevent and/or mitigate ARS symptoms are being evaluated. The CARR studies are focused on the adverse biological effects resulting from exposure to the types of radiation, at the appropriate energies, doses and dose-rates, present during an SPE (and standard reference radiations, gamma rays or electrons). The ARS is a phased syndrome which often includes vomiting and fatigue. Other acute adverse biologic effects of concern are the loss of hematopoietic cells, which can result in compromised bone marrow and immune cell functions. There is also concern for skin damage from high SPE radiation doses, including burns, and resulting immune system dysfunction. Using 3 separate animal model systems (ferrets, mice and pigs), the major ARS biologic endpoints being evaluated are: 1) vomiting/retching and fatigue, 2) hematologic changes (with focus on white blood cells) and immune system changes resulting from exposure to SPE radiation with and without reduced weightbearing conditions, and 3) skin injury and related immune system functions. In all of these areas of research, statistically significant adverse health effects have been observed in animals exposed to SPE-like radiation. Countermeasures for the management of ARS symptoms are being evaluated. New research findings from the past grant year will be discussed.

2015-01-01

Background Recent human studies confirm animal research showing that nicotine enhances reinforcement from rewards unrelated to nicotine. These effects of acute nicotine via tobacco smoking may also occur when consumed from non-tobacco products. Methods We assessed acute effects of nicotine via electronic cigarettes (“e-cigarettes”) on responding reinforced by music, video, or monetary rewards, or for no reward (control). In a fully within-subjects design, adult dependent smokers (N=28) participated in three similar experimental sessions, each following overnight abstinence (verified by CO≤10 ppm). Varying only in e-cigarette condition, sessions involved controlled exposure to a nicotine (labeled “36 mg/ml”) or placebo (“0”) e-cigarette, or no e-cigarette use. A fourth session involved smoking one’s own tobacco cigarette brand after no abstinence, specifically to compare responses under typical nicotine satiation with these acute e-cigarette conditions after abstinence. Results Reinforced responding for video reward, but not the other rewards, was greater due to use of the nicotine versus placebo e-cigarette (i.e., nicotine per se), while no differences were found between the placebo e-cigarette and no e-cigarette conditions (i.e., e-cigarette use per se). For nicotine via tobacco smoking, responding compared to the nicotine e-cigarette was similar for video but greater for music, while both video and music reward were enhanced relative to the non-nicotine conditions (placebo and no e-cigarette). Conclusions Acute nicotine from a non-tobacco product has some reinforcement enhancing effects in humans, in a manner partly consistent with nicotine via tobacco smoking and perhaps contributing to the rising popularity of nicotine e-cigarette use.

Full Text Available Hsiao-Wen Lin, E-Jian LeeNeurophysiology Laboratory, Neurosurgical Service, Department of Surgery, National Cheng Kung University Medical Center and Medical School, Tainan, TaiwanAbstract: Melatonin (N-acetyl-5-methoxy-tryptamine, a naturally occurring indole produced mainly by the pineal gland, is a well known antioxidant. Stroke (cerebral ischemia is the second leading cause of death worldwide. To date, however, effective and safe treatment for stroke remains unavailable. Melatonin is both lipid- and water-soluble and readily crosses the blood–brain barrier (BBB. Increasing evidence has shown that, in animal stroke models, administering melatonin significantly reduces infarct volume, edema, and oxidative damage and improves electrophysiological and behavioral performance. Here, we reviewed studies that assess effects of melatonin on cerebral ischemia in acute, sub-acute, and chronic stages. In addition to its potent antioxidant properties, melatonin exerts antiapoptotic, antiexcitotoxic, anti-inflammatory effects and promotes mitochondrial functions in animals with cerebral ischemia. Given that melatonin shows almost no toxicity to humans and possesses multifaceted protective capacity against cerebral ischemia, it is valuable to consider using melatonin in clinical trials on patients suffering from stroke.Keywords: cerebral ischemia, melatonin, stroke, neuroprotection

Orofacial pain in people with dementia is difficult to detect, and often under-treated. Our aim was to investigate the prevalence of orofacial pain in people with dementia in acute hospitals in the UK. Secondary aims were to examine oral health status and explore associations between orofacial pain and oral health factors. This cross-sectional observational study was carried out in two UK hospitals. Using the Orofacial Pain Scale in Non-Verbal Individuals (OPS-NVI) to identify orofacial pain, 101 participants with dementia, admitted to acute medical wards, were observed for at least 3 min during rest and chewing. Verbal participants were then asked about presence of orofacial pain, using self-report pain scales. Finally, a brief oral assessment was performed. Orofacial pain, assessed with the OPS-NVI, was present in 11.9% (95% C.I. 5.9, 18.8) of participants at rest and 21.9% (95% C.I. 14.6, 31.3) whilst chewing. Participants who were no longer able to self-report pain were significantly more likely to experience orofacial pain. Oral health in both dentate and edentate participants was poor. Brush frequency, indication of chewing quality, consistency of the food, presence of extra-oral abnormalities, person who performed mouth care, and oral hygiene in dentate participants were significant predictors for the presence of orofacial pain. Improving oral care in acute hospital patients with dementia, particularly those who cannot self-report pain, may significantly reduce pain and suffering in this population.

To present the findings of a structured literature review that aimed to identify the influences on the health, safety and welfare of adults with learning disabilities in acute hospitals. There is increasing evidence regarding the inadequacy of care for people with learning disabilities in acute care settings. However, few studies have specifically addressed their health, safety and welfare in such contexts. Four key electronic databases (Medline; PsycINFO; British Nursing Index and archive; Cumulative Index to Nursing and Allied Health Literature) were searched for relevant literature published between 2000 and 2011. Publications assessed as meeting the inclusion criteria were retrieved in full. Data were extracted regarding methods used; primary aims of the study being reported; and key findings. Of the 3505 papers identified in the initial search, eight met the inclusion criteria. Analysis revealed six areas of influence on the health, safety and welfare of adults with learning disabilities in acute hospitals: care provision (meeting health and personal needs); communication; staff attitudes; staff knowledge; supporters; and carers (valuing their role); physical environment. We represent these six areas diagrammatically, as concentric rings. These influence on health, safety and welfare form an inner (direct) layer and an outer (indirect) layer consisting of liaison services and education/training. This new conceptualisation of influences as being multi-layered assists in the identification of similarly multi-layered improvement strategies. Adults with learning disabilities can exert their own influence on health, safety and welfare and should be supported to make decisions about their own care. More broadly they should be involved with policy development, nurse education and research. This can be achieved through inclusive approaches, for example, inviting people with learning disabilities to input into nursing curricula or to engage in research as

Full Text Available Objective: To observe the effects of montelukast sodium combined with pidotimod on acute phase protein (APP and indexes of immunologic function in pediatric acute bronchitis treatment. Methods: A total of 180 cases children with acute bronchitis acted as research objects were randomly divided into control group (n=65 and observation group (n=63. On the basis of conventional therapy, control group was treated by plus pidotimod. On this base, observation group was treated with montelukast sodium. The changes of acute phase proteins (CRP, HP, a1-AAG and CER and immune function (CD3+ , CD4+ , CD8+ and CD4+ /CD8+ levels before and after treatment were observed after 2 months. Results: Before treatment, CRP, HP, a1-AAG, CER, CD3+ , CD4+ , CD8+ and CD4+ /CD8+ levels of two groups had no statistically significant difference; CRP, HP, a1-AAG, CER, and CD8+ levels of control and observation groups decreased significantly after treatment, the decreases of observation group were more obvious than that of control group, and the levels after treatment were significantly lower than that of control groups. The levels of CD3+ , CD4+ and CD4+ /CD8+ in two groups after treatment were significantly higher than those before treatment. For observation group, the levels of CD3+ , CD4+ and CD4+ /CD8+ increased more significantly after treatment, which were significantly higher than that of the control group. Conclusion: Using Montelukast sodium combined with pidotimod can effectively reduce the children's acute phase protein levels, improve immune function, which has clinical value for the treatment of children with acute bronchitis.

The Hippocratic tradition emphasized environmental causes of diseases and the need for harmony between the individual and the natural environment as the right philosophy to maintain a good health status. Public awareness and scientific attention concerning environmental pollution is usually focused on the consequent increased risk of developing cancer. Air pollution has been recognized by the World Health Organization (WHO) to cause cardiovascular and respiratroy diseases, as well as lung cancer, after acute/chronic exposure to fine particulates (PM2.5 and PM10) even at concentrations which are 50% lower than those accepted as legal limits in many developed countries. An increase of 10 µg/m³ of PM2.5 produces a +4%-6% of overall mortality, a +10% of cardiovascular disease prevalence (arithmyas, acute myocardial infarctions, and heart failure) and a +22% of lung cancer prevalence. In addition to these chronic effects, acute hospitalizations are also affected, especially among susceptible populations such as children and diabetic patients. Water and soil contamination also have an additional detrimental effect on people's health. Other issues concerning environment contamination and human health include male/female fertility, metabolic and thyroid conditions, but also professional exposures resulting in occupational diseases. Moreover, in the perspective of "gender medicine", different acute or chronic effects of environmental pollution should be specifically assessed both in men and in women. This special issue on "Environmental Diseases" is aimed at providing a global overview about different threats to human health possibily originating from environmental contamination.

Ionizing radiation affects healthy organs and tissues as well as diseased tissues during radiation therapy. Skin reactions varying from acute erythema to necrosis can be seen. It has been found that vitamin E can prevent mutagenic and/or carcinogenic effects of ionizing radiation in both animals and cell cultures. This study investigated the preventative effect of antioxidant vitamin E on irradiation-induced acute skin reactions. No protective effect of vitamin E was demonstrated. It is possible that the vehicle induced free radical exposure in the irradiated skin.

There is a well-established link between maternal depression and child mental health. Similar effects have been found for maternal history of early life maltreatment (ELM). However, studies investigating the relationship of children's quality of life and maternal depression are scarce and none have been conducted for the association with maternal ELM. The aim of the present study was to investigate the effects of maternal history of ELM and depression on children's health-related quality of life and to identify mediating factors accounting for these effects. Our study involved 194 mothers with and without history of depression and/or ELM and their children between five and 12 years. Children's health-related quality of life was assessed by maternal proxy- and child self-ratings using the KIDSCREEN. We considered maternal sensitivity and maternal parenting stress as potential mediators. We found an effect of maternal history of depression but not of maternal history of ELM on health-related quality of life. Maternal stress and sensitivity mediated the effects of maternal depression on child global health-related quality of life, as well as on the dimensions Autonomy & Parent Relation, School Environment (maternal and child rating), and Physical Wellbeing (child rating). Due to the cross-sectional design of the study, causal interpretations must be made with caution. Some scales yielded low internal consistency. Maternal impairments in areas of parenting which possibly developed during acute depression persist even after remission of acute affective symptoms. Interventions should target parenting stress and sensitivity in parents with prior depression. Copyright © 2017 Elsevier B.V. All rights reserved.

Health effects models for nuclear power plant accident consequence analysis. Modification of models resulting from addition of effects of exposure to alpha-emitting radionuclides: Revision 1, Part 2, Scientific bases for health effects models, Addendum 2

The Nuclear Regulatory Commission (NRC) has sponsored several studies to identify and quantify, through the use of models, the potential health effects of accidental releases of radionuclides from nuclear power plants. The Reactor Safety Study provided the basis for most of the earlier estimates related to these health effects. Subsequent efforts by NRC-supported groups resulted in improved health effects models that were published in the report entitled {open_quotes}Health Effects Models for Nuclear Power Plant Consequence Analysis{close_quotes}, NUREG/CR-4214, 1985 and revised further in the 1989 report NUREG/CR-4214, Rev. 1, Part 2. The health effects models presented in the 1989 NUREG/CR-4214 report were developed for exposure to low-linear energy transfer (LET) (beta and gamma) radiation based on the best scientific information available at that time. Since the 1989 report was published, two addenda to that report have been prepared to (1) incorporate other scientific information related to low-LET health effects models and (2) extend the models to consider the possible health consequences of the addition of alpha-emitting radionuclides to the exposure source term. The first addendum report, entitled {open_quotes}Health Effects Models for Nuclear Power Plant Accident Consequence Analysis, Modifications of Models Resulting from Recent Reports on Health Effects of Ionizing Radiation, Low LET Radiation, Part 2: Scientific Bases for Health Effects Models,{close_quotes} was published in 1991 as NUREG/CR-4214, Rev. 1, Part 2, Addendum 1. This second addendum addresses the possibility that some fraction of the accident source term from an operating nuclear power plant comprises alpha-emitting radionuclides. Consideration of chronic high-LET exposure from alpha radiation as well as acute and chronic exposure to low-LET beta and gamma radiations is a reasonable extension of the health effects model.

Optimal usability is crucial in providing protection for health care workers who are exposed to severe acute respiratory syndrome day and night while taking care of patients with the virus. No research study has yet tested the usability of personal protective clothing (PPC). The study was carried out in 3 stages. PPC available in Hong Kong were sorted by their physical properties in the first stage. The second stage was a single-blinded study examining the different usability aspects of the PPC. The third stage was a simulated viral load test. Four types were identified: good water repellency and water resistance, poor air permeability (Type A PPC); good water repellency and air permeability, poor water resistance (Type B PPC); poor water repellency, poor water resistance, and fair air permeability (Type C PPC); and good water repellency, poor air permeability, and fair water resistance (Type D PPC). Type D PPC had a significantly higher number of contamination sites on the subjects' dorsum and palm. Type C PPC had the highest contamination over the trunk. Findings in the viral load test showed that there was a significant difference in the contamination of the face (t=4.69, df=38, Phand contamination is lowest among the 4 groups in the current study.

Health-care costs following acute hospital care have been identified as a major contributor to regional variation in Medicare spending. This study investigated the associations of preoperative physical therapy and post-acute care resource use and its effect on the total cost of care during primary hip or knee arthroplasty. Historical claims data were analyzed using the Centers for Medicare & Medicaid Services Limited Data Set files for Diagnosis Related Group 470. Analysis included descriptive statistics of patient demographic characteristics, comorbidities, procedures, and post-acute care utilization patterns, which included skilled nursing facility, home health agency, or inpatient rehabilitation facility, during the ninety-day period after a surgical hospitalization. To evaluate the associations, we used bivariate and multivariate techniques focused on post-acute care use and total episode-of-care costs. The Limited Data Set provided 4733 index hip or knee replacement cases for analysis within the thirty-nine-county Medicare hospital referral cluster. Post-acute care utilization was a significant variable in the total cost of care for the ninety-day episode. Overall, 77.0% of patients used post-acute care services after surgery. Post-acute care utilization decreased if preoperative physical therapy was used, with only 54.2% of the preoperative physical therapy cohort using post-acute care services. However, 79.7% of the non-preoperative physical therapy cohort used post-acute care services. After adjusting for demographic characteristics and comorbidities, the use of preoperative physical therapy was associated with a significant 29% reduction in post-acute care use, including an $871 reduction of episode payment driven largely by a reduction in payments for skilled nursing facility ($1093), home health agency ($527), and inpatient rehabilitation ($172). The use of preoperative physical therapy was associated with a 29% decrease in the use of any post-acute care

Background The recovery of patients after an acute episode of illness or injury depends both on adequate medical treatment and on the early identification of needs for rehabilitation care. The process of early beginning rehabilitation requires efficient communication both between health professionals and the patient in order to effectively address all rehabilitation goals. The currently used nursing taxonomies, however, are not intended for interdisciplinary use and thus may not contribute to efficient rehabilitation management and an optimal patient outcome.

Full Text Available Abstract Background The recovery of patients after an acute episode of illness or injury depends both on adequate medical treatment and on the early identification of needs for rehabilitation care. The process of early beginning rehabilitation requires efficient communication both between health professionals and the patient in order to effectively address all rehabilitation goals. The currently used nursing taxonomies, however, are not intended for interdisciplinary use and thus may not contribute to efficient rehabilitation management and an optimal patient outcome. The ICF might be the missing link in this communication process. The objective of this study was to identify the categories of the International Classification of Functioning, Disability and Health (ICF categories relevant for nursing care in the situation of acute and early post-acute rehabilitation.

Objective: To determine the independent effects of aphasia on outcomes during acute stroke admission, controlling for total NIH Stroke Scale (NIHSS) scores and loss of consciousness. Methods: Data from the Tulane Stroke Registry were used from July 2008 to December 2014 for patient demographics, NIHSS scores, length of stay (LOS), complications (sepsis, deep vein thrombosis), and discharge modified Rankin Scale (mRS) score. Aphasia was defined as a score >1 on question 9 on the NIHSS on admission and hemiparesis as >1 on questions 5 or 6. Results: Among 1,847 patients, 866 (46%) had aphasia on admission. Adjusting for NIHSS score and inpatient complications, those with aphasia had a 1.22 day longer LOS than those without aphasia, whereas those with hemiparesis (n = 1,225) did not have any increased LOS compared to those without hemiparesis. Those with aphasia had greater odds of having a complication (odds ratio [OR] 1.44, confidence interval [CI] 1.07–1.93, p = 0.0174) than those without aphasia, which was equivalent to those having hemiparesis (OR 1.47, CI 1.09–1.99, p = 0.0137). Controlling for NIHSS scores, aphasia patients had higher odds of discharge mRS 3–6 (OR 1.42 vs 1.15). Conclusion: Aphasia is independently associated with increased LOS and complications during the acute stroke admission, adding $2.16 billion annually to US acute stroke care. The presence of aphasia was more likely to produce a poor functional outcome than hemiparesis. These data suggest that further research is necessary to determine whether establishing adaptive communication skills can mitigate its consequences in the acute stroke setting. PMID:27765864

The health effects of depleted uranium (DU) are mainly caused by its chemical toxicity. Although the kidneys are the main target organs for uranium toxicity, uranium can also reach the brain. In this paper, the central effects of acute exposure to DU were studied in relation to health parameters and the sleep-wake cycle of adult rats. Animals were injected intraperitoneally with 144+/-10 microg DU kg-1 as nitrate. Three days after injection, the amounts of uranium in the kidneys represented 2.6 microg of DU g-1 of tissue, considered as a sub-nephrotoxic dosage. The central effect of uranium could be seen through a decrease in food intake as early as the first day after exposure and shorter paradoxical sleep 3 days after acute DU exposure (-18% of controls). With a lower dosage of DU (70+/-8 microg DU kg-1), no significant effect was observed on the sleep-wake cycle. The present study intends to illustrate the fact that the brain is a target organ, as are the kidneys, after acute exposure to a moderate dosage of DU. The mechanisms by which uranium causes these early neurophysiological perturbations shall be discussed.

J Strength Cond Res 25(12): 3319-3325, 2011-This study examined the acute potentiating effects of back squats on athlete performance with a specific focus on movement specificity and the individual timing of potentiation. Nine subelite male rugby players performed 3 protocols on separate occasions using a randomized, crossover, and counterbalanced design. Each protocol consisted of performance testing before a single set of 3 repetition maximum (3RM) back squats, followed by retesting at ∼15 seconds, 4, 8, 12, and 16 minutes. The 3 tests were countermovement jumps (CMJs), sprint performance (5 and 10 m), and 3-m horizontal sled pushes with a 100-kg load. Relationships between the individual changes in salivary testosterone and cortisol concentrations and performance were also examined. The 3RM squats significantly (p squats was found effective in acutely enhancing CMJ height in the study population, especially when the recovery period was individualized for each athlete. The study results also suggest that the potentiating effects of squats may exhibit some degree of movement specificity, being greater for those exercises with similar movement patterns. The current findings have practical implications for prescribing warm-up exercises, individualizing training programs, and for interpreting postactivation potentiation research.

Air pollution has been accepted as an important contributor to asthma development and exacerbation. However, the evidence is limited in China. In this study, we investigated the acute effect of air pollution on asthma hospitalization in Shanghai, China. We applied over-dispersed generalized additive model adjusted for weather conditions, day of the week, long-term and seasonal trends. An interquartile range increase in the moving average concentrations of PM 10 , SO 2 , NO 2 and BC on the concurrent day and previous day corresponded to 1.82%, 6.41%, 8.26% and 6.62% increase of asthmatic hospitalization, respectively. The effects of SO 2 and NO 2 were robust after adjustment for PM 10 . The associations appeared to be more evident in the cool season than in the warm season. Our results contribute to the limited data in the scientific literature on acute effects of air pollution on asthma in high exposure settings, which are typical in developing countries. - Highlights: • Few prior studies in China examine the effect of air pollution on asthma. • We found acute effect of air pollution on asthma hospitalization in Shanghai. • Our results contribute to limited data on air pollution and asthma in China. - Ambient air pollution increases the risk of asthma hospitalization in Shanghai, China

Design elements of clinical trials can introduce recruitment bias and reduce study efficiency. Trials involving the critically ill may be particularly prone to design-related inefficiencies. Enrollment into the Veterans Affairs/National Institutes of Health Acute Renal Failure Trial Network Study was systematically monitored. Reasons for nonenrollment into this study comparing strategies of renal replacement therapy in critically ill patients with acute kidney injury were categorized as modifiable or nonmodifiable. 4339 patients were screened; 2744 fulfilled inclusion criteria. Of these, 1034 were ineligible by exclusion criteria. Of the remaining 1710 patients, 1124 (65.7%) enrolled. Impediments to informed consent excluded 21.4% of potentially eligible patients. Delayed identification of potential patients, physician refusal, and involvement in competing trials accounted for 4.4, 2.7, and 2.3% of exclusions. Comfort measures only status, chronic illness, chronic kidney disease, and obesity excluded 11.8, 7.8, 7.6, and 5.9% of potential patients. Modification of an enrollment window reduced the loss of patients from 6.6 to 2.3%. The Acute Renal Failure Trial Network Study's enrollment efficiency compared favorably with previous intensive care unit intervention trials and supports the representativeness of its enrolled population. Impediments to informed consent highlight the need for nontraditional acquisition methods. Restrictive enrollment windows may hamper recruitment but can be effectively modified. The low rate of physician refusal acknowledges clinical equipoise in the study design. Underlying comorbidities are important design considerations for future trials that involve the critically ill with acute kidney injury.

Chronic and acute exposure to toxic aerosols belongs to frequent causes of airway diseases. However, asthma attacks due to long-distance inhalative exposure to organic solvents, transmitted via an air condition system, have not been reported so far. The present case illustrates the possibility of air conditioning systems as non-infectious health hazards in occupational medicine. So far, only infectious diseases such as legionella pneumophila pneumonia have commonly been associated to air-conditioning exposures but physicians should be alert to the potential of transmission of toxic volatile substances via air conditioning systems. In view of the events of the 11th of September 2001 with a growing danger of large building terrorism which may even use air conditioning systems to transmit toxins, facility management security staff should be alerted to possible non-infectious toxic health hazards arising from air-conditioning systems.

Full Text Available In Italy, urban wastewater disinfection is regulated in the third part of Legislative Decree n. 152/2006, which states that wastewater treatment plants (WWTPs must include a disinfection unit, with a capacity exceeding 2000 Population Equivalent (PE. This treatment shall ensure microbial quality and health security. The legislation provides the following limits for wastewater: Escherichia coli (E. coli concentration below 5000 CFU 100 mL−1 (recommended value, active chlorine concentration below 0.2 mg L−1 and lack of acute toxicity. The compliance with these conditions is shown by means of the study of correct disinfectant dosage, which also depends on wastewater characteristics. An investigation at the regional level (from 2013 to 2016 shows a correlation between acute toxicity discharge and disinfection treatment through chemical reagents (mainly with the use of chlorine compounds and peracetic acid. The experimental work concerns two active sludge WWTPs in northern Italy with small capacity (10,000–12,000 PE. The activities provide the assessment of microbiological quality and toxicity of WWTPs effluents in relation to the dosage of sodium hypochlorite and peracetic acid, by means of the use of batch tests. The results show that with similar disinfectant dosage and comparable initial E. coli concentration, peracetic acid exhibits the best performance in terms of microbial removal (with removal yields up to 99.99%. Moreover, the acute toxicity was evident at higher doses and therefore with higher residuals of peracetic acid (2.68 mg L−1 compared to the free residual chlorine (0.17 mg L−1.

Although ample evidence has shown that acute stress impairs memory, the influences of acute stress on different phases of memory, such as acquisition, consolidation and retrieval, are different. Experimental data from both human and animals support that endogenous opioid system plays a role in stress, as endogenous opioid release is increased and opioid receptors are activated during stress experience. On the other hand, endogenous opioid system mediates learning and memory. The aim of the present study was to investigate the effect of acute forced swimming stress on recognition memory of C57 mice and the role of opioid receptors in this process by using a three-day pattern of new object recognition task. The results showed that 15-min acute forced swimming damaged the retrieval of recognition memory, but had no effect on acquisition and consolidation of recognition memory. No significant change of object recognition memory was found in mice that were given naloxone, an opioid receptor antagonist, by intraperitoneal injection. But intraperitoneal injection of naloxone before forced swimming stress could inhibit the impairment of recognition memory retrieval caused by forced swimming stress. The results of real-time PCR showed that acute forced swimming decreased the μ opioid receptor mRNA levels in whole brain and hippocampus, while the injection of naloxone before stress could reverse this change. These results suggest that acute stress may impair recognition memory retrieval via opioid receptors.

Status epilepticus is a life threatening neurological medical emergency. It may cause serious damage to the brain and even death in many cases if not treated properly. There is limited choice of drugs for the short term and long term management of status epilepticus and the dugs recommended for status epilepticus possess various side effects. The present study was designed to investigate synergistic anticonvulsant effects of pregabalin with amlodipine on acute seizure model of epilepsy in mice. Pentylenetetrazole was used to induce acute seizures which mimic status epilepticus. Pregabalin and amlodipine were used in combination to evaluate synergistic anti-seizure effects on acute seizure model of epilepsy in mice. Diazepam and valproate were used as reference dugs. The acute anti-convulsive activity of pregabalin with amlodipine was evaluated in vivo by the chemical induced seizures and their anti-seizure effects were compared with pentylenetetrazole, reference drugs and to their individual effects. The anti-seizure effects of tested drugs were recorded in seconds on seizure characteristics such as latency of onset of threshold seizures, rearing and fallings and Hind limbs tonic extensions. The seizure protection and mortality to the animals exhibited by the drugs were recorded in percentage. Combination regimen of pregabalin with amlodipine exhibited dose dependent significant synergistic anticonvulsant effects on acute seizures which were superior to their individual effects and equivalent to reference drugs.

Background: Children who recover from moderate acute malnutrition (MAM) have high rates of relapse in the year after nutritional recovery. Interventions to decrease these adverse outcomes are needed to maximize the overall effectiveness of supplemental feeding programs (SFPs). Objective: We evaluated the effectiveness of a package of health and nutrition interventions on improving the proportion of children who sustained recovery for 1 y after MAM treatment. We further explored factors related to sustained recovery. Design: We conducted a cluster-randomized clinical effectiveness trial involving rural Malawian children aged 6-62 mo who were enrolled on discharge from an SFP for MAM. We enrolled 718 children at 10 control sites and 769 children at 11 intervention sites. In addition to routine health and nutrition counseling, the intervention group received a package of health and nutrition interventions that consisted of a lipid nutrient supplement, deworming medication, zinc supplementation, a bed net, and malaria chemoprophylaxis. A survival analysis was used to determine the effectiveness of the intervention as well as to identify factors associated with sustained recovery. Results: Of 1383 children who returned for the full 12-mo follow-up period, 407 children (56%) and 347 children (53%) sustained recovery in the intervention and control groups, respectively. There was no significant difference in relapse-free survival curves between the treatment and control groups ( P = 0.380; log-rank test). The risk factors for relapse or death after initial recovery were a smaller midupper arm circumference on SFP admission ( P = 0.01) and discharge ( P nutrition services in addition to traditional SFP treatment has no significant effect on improving sustained recovery in children after treatment of MAM.

Despite the widespread implementation of the World Health Organization (WHO) guidelines for the management of severe malnutrition in South Africa, poor treatment outcomes for children under 5 years are still observed in some hospitals, particularly in rural areas. To explore health care workers' perceptions about upstream and proximal factors contributing to poor treatment outcomes for severe acute malnutrition in two district hospitals in South Africa. An explorative descriptive qualitative study was conducted. Four focus group discussions were held with 33 hospital staff (senior clinical and management staff, and junior clinical staff) using interview guide questions developed based on the findings from an epidemiological study that was conducted in the same hospitals. Qualitative data were analysed using the framework analysis. Most respondents believed that critical illness, which was related to early and high case fatality rates on admission, was linked to a web of factors including preference for traditional medicine over conventional care, gross negligence of the child at household level, misdiagnosis of severe malnutrition at the first point of care, lack of specialised skills to deal with complex presentations, shortage of patient beds in the hospital and policies to discharge patients before optimal recovery. The majority believed that the WHO guidelines were effective and relatively simple to implement, but that they do not make much difference among severe acute malnutrition cases that are admitted in a critical condition. Poor management of cases was linked to the lack of continuity in training of rotating clinicians, sporadic shortages of therapeutic resources, inadequate staffing levels after normal working hours and some organisational and system-wide challenges beyond the immediate control of clinicians. Findings from this study suggest that effective management of paediatric severe acute malnutrition in the study setting is affected by a

Environment and Health: Not Only Cancer

Full Text Available The Hippocratic tradition emphasized environmental causes of diseases and the need for harmony between the individual and the natural environment as the right philosophy to maintain a good health status. Public awareness and scientific attention concerning environmental pollution is usually focused on the consequent increased risk of developing cancer. Air pollution has been recognized by the World Health Organization (WHO to cause cardiovascular and respiratroy diseases, as well as lung cancer, after acute/chronic exposure to fine particulates (PM2.5 and PM10 even at concentrations which are 50% lower than those accepted as legal limits in many developed countries. An increase of 10 µg/m3 of PM2.5 produces a +4%–6% of overall mortality, a +10% of cardiovascular disease prevalence (arithmyas, acute myocardial infarctions, and heart failure and a +22% of lung cancer prevalence. In addition to these chronic effects, acute hospitalizations are also affected, especially among susceptible populations such as children and diabetic patients. Water and soil contamination also have an additional detrimental effect on people’s health. Other issues concerning environment contamination and human health include male/female fertility, metabolic and thyroid conditions, but also professional exposures resulting in occupational diseases. Moreover, in the perspective of “gender medicine”, different acute or chronic effects of environmental pollution should be specifically assessed both in men and in women. This special issue on “Environmental Diseases” is aimed at providing a global overview about different threats to human health possibily originating from environmental contamination.

Determine the incremental health care costs associated with the diagnosis and treatment of acute otitis media (AOM) in children. Cross-sectional analysis of a national health-care cost database. Pediatric patients (age children with and without a diagnosis of AOM, adjusting for age, sex, region, race, ethnicity, insurance coverage, and Charlson comorbidity Index. A total of 8.7 ± 0.4 million children were diagnosed with AOM (10.7 ± 0.4% annually, mean age 5.3 years, 51.3% male) among 81.5 ± 2.3 million children sampled (mean age 8.9 years, 51.3% male). Children with AOM manifested an additional +2.0 office visits, +0.2 emergency department visits, and +1.6 prescription fills (all P <0.001) per year versus those without AOM, adjusting for demographics and medical comorbidities. Similarly, AOM was associated with an incremental increase in outpatient health care costs of $314 per child annually (P <0.001) and an increase of $17 in patient medication costs (P <0.001), but was not associated with an increase in total prescription expenses ($13, P = 0.766). The diagnosis of AOM confers a significant incremental health-care utilization burden on both patients and the health care system. With its high prevalence across the United States, pediatric AOM accounts for approximately $2.88 billion in added health care expense annually and is a significant health-care utilization concern. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

The discovery of endothelial progenitor cells (EPCs) may help to explain observed cardiovascular effects associated with inhaled nickel nanoparticle exposures, such as increases in vascular inflammation, generation of reactive oxygen species, altered vasomotor tone and potentiated atherosclerosis in murine species. Following an acute whole body inhalation exposure to 500 µg/m(3) of nickel nanoparticles for 5 h, bone marrow EPCs from C57BL/6 mice were isolated. EPCs were harvested for their RNA or used in a variety of assays including chemotaxis, tube formation and proliferation. Gene expression was assessed for important receptors involved in EPC mobilization and homing using RT-PCR methods. EPCs, circulating endothelial progenitor cells (CEPCs), circulating endothelial cells (CECs) and endothelial microparticles (EMPs) were quantified on a BD FACSCalibur to examine endothelial damage and repair associated with the exposure. Acute exposure to inhaled nickel nanoparticles significantly increased both bone marrow EPCs as well as their levels in circulation (CEPCs). CECs were significantly elevated indicating that endothelial damage occurred due to the exposure. There was no significant difference in EMPs between the two groups. Tube formation and chemotaxis, but not proliferation, of bone marrow EPCs was impaired in the nickel nanoparticle exposed group. These results coincided with a decrease in the mRNA of receptors involved in EPC mobilization and homing. These data provide new insight into how an acute nickel nanoparticle exposure to half of the current Occupational Safety & Health Administration (OSHA) permissible exposure limit may adversely affect EPCs and exacerbate cardiovascular disease states.

To create acute pancreatitis condition experimentally in rats using cerulein, and to reveal histopathological effects in pancreatic tissue with erdosteine. An experimental study. Department of General Surgery, Duzce University, Turkey, from June to October 2014. Thirty male Wistar albino rats were divided into three groups. No procedures were applied to Group 1. The rats in Group 2 and Group 3 were injected cerulein, to establish an experimental pancreatitis model and the blood amylase and lipase values were examined. The rats in Group 3 were given 10 mg/kg erdosteine. This treatment was continued for another 2 days and the rats were sacrificed. The pancreatic tissues were examined histopathologically for edema, inflammation, acinar necrosis, fat necrosis, and vacuolization. The lipase and amylase values and the histopathological examination of pancreatic tissues evidenced that the experimental acute pancreatitis model was established and edema, inflammation, acinar necrosis, fat necrosis, and vacuolization were observed in the pancreatic tissues. The statistical results suggest that erdosteine can decrease the edema, inflammation, acinar necrosis, fat necrosis and vacuolization scores in the tissues. The severity of acute pancreatitis, induced by cerulein in rats, is reduced with the use of erdosteine.

Exercise improves cardiometabolic and vascular function, although the mechanisms remain unclear. Our objective was to demonstrate the diversity of circulating extracellular RNA (ex-RNA) release during acute exercise in humans and its relevance to exercise-mediated benefits on vascular inflammation. We performed plasma small RNA sequencing in 26 individuals undergoing symptom-limited maximal treadmill exercise, with replication of our top candidate miRNA in a separate cohort of 59 individuals undergoing bicycle ergometry. We found changes in miRNAs and other ex-RNAs with exercise (e.g., Y RNAs and tRNAs) implicated in cardiovascular disease. In two independent cohorts of acute maximal exercise, we identified miR-181b-5p as a key ex-RNA increased in plasma after exercise, with validation in a separate cohort. In a mouse model of acute exercise, we found significant increases in miR-181b-5p expression in skeletal muscle after acute exercise in young (but not older) mice. Previous work revealed a strong role for miR-181b-5p in vascular inflammation in obesity, insulin resistance, sepsis, and cardiovascular disease. We conclude that circulating ex-RNAs were altered in plasma after acute exercise target pathways involved in inflammation, including miR-181b-5p. Further investigation into the role of known (e.g., miRNA) and novel (e.g., Y RNAs) RNAs is warranted to uncover new mechanisms of vascular inflammation on exercise-mediated benefits on health. NEW & NOTEWORTHY How exercise provides benefits to cardiometabolic health remains unclear. We performed RNA sequencing in plasma during exercise to identify the landscape of small noncoding circulating transcriptional changes. Our results suggest a link between inflammation and exercise, providing rich data on circulating noncoding RNAs for future studies by the scientific community.

However, the antagonistic effects of DHEAS on γ-amino-butyric acidA receptors and its facilitatory action on glutamatergic neurotransmission might lead to enhanced brain excitability and seizures and thus limit DHEAS therapeutic applications. The aim of this study was to investigate possible age and sex differences in the neuronal excitability of the mice following acute and chronic DHEAS administration.Methods: DHEAS was administered intraperitoneally in male and female adult and old mice either acutely or repeatedly once daily for 4 weeks in a 10 mg/kg dose. To investigate the potential proconvulsant properties of DHEAS, we studied the effects of acute and chronic DHEAS treatment on picrotoxin-, pentylentetrazole-, and N-methyl-d-aspartate-induced seizures in mice. The effects of acute and chronic DHEAS administration on the locomotor activity, motor coordination, and body weight of the mice were also studied. We also investigated the effects of DHEAS treatment on [3H]flunitrazepam binding to the mouse brain membranes.Results: DHEAS did not modify the locomotor activity, motor coordination, body weight, and brain [3H]flunitrazepam binding of male and female mice.

Higher body mass index (BMI) is associated with lower circulating levels of N-terminal-pro-b-type natriuretic peptide (NT-proBNP). The Interaction between BMI and NT-proBNP with respect to clinical outcomes is not well characterized in patients with acute heart failure. A total of 686 patients from the biomarker substudy of the ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated HF ) clinical trial with documented NT-proBNP levels at baseline were included in the present analysis. Patients were classified by the World Health Organization obesity classification (nonobese: BMI value of NT-proBNP was not modified by BMI in this acute heart failure population. NT-proBNP remains a useful prognostic indicator of long-term mortality in acute heart failure even in the obese patient. URL: http://www.clinicaltrials.gov.

Issues in casemix funding for acute inpatient psychiatric services and their relevance to mental health nursing.

Science.gov (United States)

Fanker, S

1996-09-01

With increased recognition by government, health administrators, and clinicians of the need to simultaneously contain health expenditure, improve the productivity and efficiency of health services and maintain quality of patient care, applications of casemix funding have been advocated as an alternative means of financing acute hospital care. Currently in Australia, the Commonwealth's casemix development program is encouraging the States and Territories to participate in certain casemix initiatives. Acute psychiatric hospital care and treatment have been excluded from the initial stages of the implementation of casemix in recognition of a number of inherent obstacles or challenges affecting the utility and accuracy of casemix in funding the psychiatric sector. Despite anecdotal claims that the reduced length of stay that often occurs under casemix payment systems may negatively impact upon the quality of care and patient outcomes, to date little empirical research has been directed towards measuring the potential impact of psychiatric casemix on the quality of patient care. Psychiatry cannot afford to ignore the casemix debate on account of its current exclusion from the early phases of implementation. To do so is to run the risk of having casemix imposed at some later stage in the absence of consultation. In the meantime it is vital that mental health professionals, including nurses, participate in the development and implementation of casemix, and contribute to research aimed at increasing or maximizing the relevance of casemix to the funding of psychiatric services.

To examine the use and effectiveness of essential oil therapeutic interventions on pain, nausea, and anxiety, when provided by nurses to patients in acute hospital settings across a large health system. This study expands upon the limited body of literature on aromatherapy use among inpatients. Retrospective, effectiveness study using data obtained from electronic health records. Ten Allina Health hospitals located in Minnesota and western Wisconsin. Nurse-delivered aromatherapy. Change in patient-reported pain, anxiety, and nausea, rated before and after receiving aromatherapy using a numeric rating scale (0-10). There were 10,262 hospital admissions during the study time frame in which nurse-delivered aromatherapy was part of patient care. The majority of admissions receiving aromatherapy were females (81.71%) and white (87.32%). Over 75% of all aromatherapy sessions were administered via inhalation. Lavender had the highest absolute frequency (49.5%) of use regardless of mode of administration, followed by ginger (21.2%), sweet marjoram (12.3%), mandarin (9.4%), and combination oils (7.6%). Sweet marjoram resulted in the largest single oil average pain change at -3.31 units (95% CI: -4.28, -2.33), while lavender and sweet marjoram had equivalent average anxiety changes at -2.73 units, and ginger had the largest single oil average change in nausea at -2.02 units (95% CI: -2.55, -1.49). Essential oils generally resulted in significant clinical improvements based on their intended use, although each oil also showed ancillary benefits for other symptoms. Future research should explore use of additional essential oils, modes of administration, and different patient populations. Copyright © 2016. Published by Elsevier Ltd.

Exposure-response functions for health effects of air pollutants based on epidemiological findings

Energy Technology Data Exchange (ETDEWEB)

Aunan, K

1995-10-01

The objective of this report is to provide exposure-response functions for health effects and air pollution, which can be used in cost-effectiveness analyses of abatement measures. When cost-effective abatement strategies for air pollution are analyzed, and when air quality standards are set, it is important to have quantitative knowledge about health damage. In spite of their shortcomings, epidemiological studies provide a sound basis for exposure-response functions because they involve a random cross section of the population. In this report the exposure-response functions apply to the relation between air pollutant concentrations and relative effect frequencies, and involve the following health effect end-points: acute and chronic respiratory symptoms in children and adults, asthma episodes in children and adults, eye irritations, headache, lung damage in children, excess mortality, lung cancer incidence. The effects are attributed to one indicator component, which in many cases is particles, but for some effects NO{sub 2}, SO{sub 2}, O{sub 3}, or CO. A calculation procedure is suggested which makes it possible to estimate excess annual symptom-days for short-term effects using the annual average concentration. 103 refs., 1 table

Full Text Available Encephalitis presents with seizures in the acute phase and increases the risk of late unprovoked seizures and epilepsy. This study aimed to evaluate the effect of antiepileptic drugs in pediatric patients with acute seizures due to encephalitis and epilepsy.Cases of acute pediatric encephalitis between January 2000 and December 2010 were reviewed. Clinical data, including onset at age, seizure type, seizure frequency, effects of antiepileptic drugs, and prognosis were analyzed.During the study period, 1038 patients (450 girls, 588 boys were enrolled. Among them, 44.6% (463 had seizures in the acute phase, 33% had status epilepticus, and 26% (251 developed postencephalitic epilepsy. At one year of follow-up, 205 of the 251 patients with postencephalitic epilepsy were receiving antiepileptic drugs while 18% were seizure free even after discontinuing the antiepileptic drugs. Among those with postencephalitic epilepsy, 67% had favorable outcomes and were using <2 anti-epileptic drugs while 15% had intractable seizures and were using ≥ 2 antiepileptic drugs. After benzodiazepines, intravenous phenobarbital was preferred over phenytoin as treatment of postencephalitic seizures in the acute phase. For refractory status epilepticus, high-dose topiramate combined with intravenous high-dose phenobarbital or high-dose lidocaine had less side effects.Children with encephalitis have a high rate of postencephalitic epilepsy. Phenobarbital and clonazepam are the most common drugs used, alone or in combination, for postencephalitic epilepsy.

Full Text Available Abstract Background On July 27 2003, a ship carrying crude oil run aground near Karachi and after two weeks released 37,000 tons of its cargo into the sea. Oil on the coastal areas and fumes in air raised health concerns among people. We assessed the immediate health impact of oil spill from the tanker Tasman Spirit on residents of the affected coastline in Karachi, Pakistan. Methods We conducted a study consisting of an exposed group including adults living in houses on the affected shoreline and two control groups (A and B who lived at the distance of 2 km and 20 km away from the sea, respectively. We selected households through systematic sampling and interviewed an adult male and female in each household about symptoms relating to eyes, respiratory tract, skin and nervous system, smoking, allergies, beliefs about the effect on their health and anxiety about the health effects. We used logistic regression procedures to model each symptom as an outcome and the exposure status as an independent variable while adjusting for confounders. We also used linear regression procedure to assess the relationship exposure status with symptoms score; calculated by summation of all symptoms. Results Overall 400 subjects were interviewed (exposed, n = 216; group A, n = 83; and group B, n = 101. The exposed group reported a higher occurrence of one or more symptoms compared to either of the control groups (exposed, 96% vs. group A, 70%, group B 85%; P P Conclusion Results suggest that the occurrence of increased symptoms among the exposed group is more likely to be due to exposure to the crude oil spill.

Burnoffs (intentional fires for agricultural purposes) and forest fires of large proportions have been observed in various regions of the planet. Exposure to high levels of air pollutants emitted by fires can be responsible for various harmful effects on human health. In this article, the literature on estimating acute effects of air pollution on human health by fires in the regions with the highest number of fires on the planet, using a time series approach is summarized. An attempt was made to identify gaps in knowledge. The study consisted of a narrative review, in which the characteristics of the selected studies were grouped by regions of the planet with a higher incidence of burnoffs: Amazon, America, Australia and Asia. The results revealed a large number of studies in Australia, few studies in the Amazon and great heterogeneity in the results on the significant effects on human health.

A great number of antineoplastic drugs (ANPDs) are used globally in cancer treatment. Due to their adverse health effects, occupational exposure to ANPDs is considered a potential health risk to health care workers. The current study aimed to evaluate safe-handling practices of ANPDs, exposure controls, and adverse health implications for health care providers exposed to ANDPs. Prevention measures, including engineering, administrative, and work practice controls, as well as personal protective equipment (PPE), were recorded daily through a questionnaire for six weeks. Acute adverse health effects experienced by health care workers were also documented. The implemented exposure controls for preparation, administration, cleaning, and waste disposal were not in accordance with the safe handling guidelines. Central nervous system disorders (26.33%) were the most frequent acute adverse effects reported by health care workers. A significant correlation was found between the number of experienced adverse effects and handling characteristics, including the number of preparations (r = 0.38, p health care workers were in danger of exposure to ANPDs and experienced acute adverse health effects. Implementation of appropriate exposure controls is required to prevent occupational exposure to ANPDs.

The purpose of this paper is to evaluate the views of stove users in Ulaanbaatar, Mongolia on how stoves affect their health. In this paper focus groups were conducted with improved stove users; traditional stove users; and a mix of traditional and improved stove users. Individual interviews were also held with various types of stove users. A translator moderated all discussions with a questioning route. All discussions were fully transcribed and translated. The transcripts were analysed by identifying common themes in responses to form an emerging theory. The findings in the paper are that all stove users recognised respiratory symptoms caused by stove smoke and other health effects such as warmth, dirt and workload, which they perceived to be important. Stove users had a lack of knowledge about the diseases caused by the smoke. Public health was a key driver for the improved stove project, yet has been neglected in improved stove marketing. The study used in this paper was limited by the language barrier. Some of the meanings of participants' responses may have been lost in translation. This paper has highlighted the importance of the health effects of stove smoke to stove users. Uptake of the improved stoves has been low. Public health should be included in marketing strategies for improved stoves to increase their uptake. The paper shows that acute respiratory infections are a major cause of mortality world-wide. Indoor air pollution from burning biomass fuels in household stoves causes a significant proportion of respiratory infections. No qualitative research has been published exploring stove users' views on the health effects of stoves. This paper provides an insight into stove users' perceptions for those interested in people-centred approaches to tackling international health issues.

Purpose: To identify dosimetric variables predictive of acute gastrointestinal (GI) and genitourinary (GU) toxicity and to determine whether hormonal therapy (HT) is independently associated with acute GI and GU toxicity in prostate cancer patients treated with conformal radiotherapy (RT). Methods and Materials: This analysis was performed on 336 patients participating in a multicenter (four hospitals) randomized trial comparing 68 Gy and 78 Gy. The clinical target volume consisted of the prostate with or without the seminal vesicles, depending on the risk of seminal vesicle involvement. The margin from the clinical target volume to the planning target volume was 1 cm. For these patients, the treatment plan for a total dose of 68 Gy was used, because nearly all toxicity appeared before the onset of the 10-Gy boost. Acute toxicity ( 3 months before RT). Results: Acute GI toxicity Grade 2 or worse was seen in 46% of the patients. Patients with long-term neoadjuvant HT experienced less Grade 2 or worse toxicity (27%) compared with those receiving short-term neoadjuvant HT (50%) and no HT (50%). The volumes of the prostate and seminal vesicles were significantly smaller in both groups receiving neoadjuvant HT compared with those receiving no HT. In multivariate logistic regression analysis, including the two statistically significant clinical variables neoadjuvant HT and hospital, a volume effect was found for the relative, as well as absolute, rectal wall volumes exposed to intermediate and high doses. Of all the length parameters, the relative rectal length irradiated to doses of ≥5 Gy and ≥30 Gy and absolute lengths receiving ≥5-15 and 30 Gy were significant. Acute GU toxicity Grade 2 or worse was reported in 56% of cases. For patients with pretreatment GU symptoms, the rate was 93%. The use of short-term and long-term neoadjuvant HT resulted in more GU toxicity (73% and 71%) compared with no HT (50%). In multivariate analysis, containing the variables

In Catalonia the current surveillance systems do not allow to know the true incidence or the health care utilization of acute gastroenteritis (AGE) caused by Campylobacter and Salmonella infections. The aim of this study is to analyze these characteristics. Descriptive study of Campylobacter and Salmonella infections reported in 2002 and 2012 in Catalonia, Spain. We included cases isolated and reported by the laboratory to a regional Surveillance Unit. The estimated incidence of Salmonella and Campylobacter AGE decreased by almost 50% and 20% respectively in 2012. Children between one and 4 years old were the most affected in both years. Significant differences in the clinical characteristics and disease duration were observed between Campylobacter and Salmonella. Visits to the Emergency Department and hospitalization rates were 63.7% and 15%, being more frequent among salmonellosis cases. The estimated incidence of Campylobacter and Salmonella infections has decreased, however rates are still important, as well as it is the health care utilization in both diseases. Current surveillance systems need appropriateness improvements to reach a better control of these infections. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Exposure to 3, 4- methylenedioxymethamphetamine (MDMA) could lead to serotonergic system toxicity in the brain. This system is responsible for learning and memory functions. Studies show that MDMA causes memory impairment dose-dependently and acutely. The present study was designed to evaluate the chronic and acute effects of MDMD on spatial memory and acquisition of passive avoidance. Adult male Wistar rats (200-250 g) were given single or multiple injections of MDMA (10 mg/kg, IP). Using passive avoidance and Morris Water Maze (MWM) tasks, learning and spatial memory functions were assessed. The data were analyzed by SPSS 16 software and one- way analysis of variance (ANOVA) test. Our results showed that there were significant differences in latency to enter the dark compartment (STL) between sham and MDMA- treated groups. Acute group significantly showed more STL in comparison with chronic group. Furthermore, MDMA groups spent more time in dark compartment (TDS) than the sham group. Administration of single dose of MDMA significantly caused an increase in TDS compared with the chronic group. In the MWM, MDMA treatment significantly increased the traveled distance and escaped latency compared to the sham group. Like to passive avoidance task, percentage of time spent in the target quadrant in MDMA- treated animals impaired in MWM compared with sham group. These data suggest that MDMA treatment impairs learning and memory functions that are more extensive in acute- treated rats.

There is a paucity of research exploring Indigenous women's experiences in acute mental health inpatient services in Australia. Even less is known of Indigenous women's experience of seclusion events, as published data are rarely disaggregated by both indigeneity and gender. This research used secondary analysis of pre-existing datasets to identify any quantifiable difference in recorded experience between Indigenous and non-Indigenous women, and between Indigenous women and Indigenous men in an acute mental health inpatient unit. Standard separation data of age, length of stay, legal status, and discharge diagnosis were analysed, as were seclusion register data of age, seclusion grounds, and number of seclusion events. Descriptive statistics were used to summarize the data, and where warranted, inferential statistical methods used SPSS software to apply analysis of variance/multivariate analysis of variance testing. The results showed evidence that secondary analysis of existing datasets can provide a rich source of information to describe the experience of target groups, and to guide service planning and delivery of individualized, culturally-secure mental health care at a local level. The results are discussed, service and policy development implications are explored, and suggestions for further research are offered. © 2016 Australian College of Mental Health Nurses Inc.

Objective To assess the validity of a predictive model of health literacy, and to examine the relationship between derived health literacy estimates and 30-day hospital readmissions for acute myocardial infarction (AMI). Design Retrospective cohort study. Setting and participants A National Institute of Aging (NIA) study cohort of 696 adult, English-speaking primary care patients, aged 55–74 years, was used to assess the validity of derived health literacy estimates. Claims from 7733 Medicare beneficiaries hospitalised for AMI in 2008 in North Carolina and Illinois were used to investigate the association between health literacy estimates and 30-day hospital readmissions. Measures The NIA cohort was administered 3 common health literacy assessments (Newest Vital Sign, Test of Functional Health Literacy in Adults, and Rapid Estimate of Adult Literacy in Medicine). Health literacy estimates at the census block group level were derived via a predictive model. 30-day readmissions were measured from Medicare claims data using a validated algorithm. Results Fair agreement was found between derived estimates and in-person literacy assessments (Pearson Correlation coefficients: 0.38–0.51; κ scores: 0.38–0.40). Medicare enrollees with above basic literacy according to derived health literacy estimates had an 18% lower risk of a 30-day readmission (RR=0.82, 95% CI 0.73 to 0.92) and 21% lower incidence rate of 30-day readmission (IRR=0.79, 95% CI 0.68 to 0.87) than patients with basic or below basic literacy. After adjusting for demographic and clinical characteristics, the risk of 30-day readmission was 12% lower (p=0.03), and the incidence rate 16% lower (pliteracy. Conclusions Health literacy, as measured by a predictive model, was found to be a significant, independent predictor of 30-day readmissions. As a modifiable risk factor with evidence-based solutions, health literacy should be considered in readmission reduction efforts. PMID:26068508

Acute Moderate Exercise Improves Mnemonic Discrimination in Young Adults

Increasing evidence suggests that regular moderate exercise increases neurogenesis in the dentate gyrus (DG) of the hippocampus and improves memory functions in both humans and animals. The DG is known to play a role in pattern separation, which is the ability to discriminate among similar experiences, a fundamental component of episodic memory. While long-term voluntary exercise improves pattern separation, there is little evidence of alterations in DG function after an acute exercise session. Our previous studies showing acute moderate exercise-enhanced DG activation in rats, and acute moderate exercise-enhanced prefrontal activation and executive function in humans, led us to postulate that acute moderate exercise may also activate the hippocampus, including more specifically the DG, thus improving pattern separation. We thus investigated the effects of a 10-min moderate exercise (50% V̇O2peak) session, the recommended intensity for health promotion, on mnemonic discrimination (a behavioral index of pattern separation) in young adults. An acute bout of moderate exercise improved mnemonic discrimination performance in high similarity lures. These results support our hypothesis that acute moderate exercise improves DG-mediated pattern separation in humans, proposing a useful human acute-exercise model for analyzing the neuronal substrate underlying acute and regular exercise-enhanced episodic memory based on the hippocampus.

Full Text Available Abstract Background Debate continues as to whether acute bronchodilator responsiveness (BDR predicts long-term outcomes in COPD. Furthermore, there is no consensus on a threshold for BDR. Methods At baseline and during the 4-year Understanding Potential Long-term Improvements in Function with Tiotropium (UPLIFT® trial, patients had spirometry performed before and after administration of ipratropium bromide 80 mcg and albuterol 400 mcg. Patients were split according to three BDR thresholds: ≥12% + ≥200 mL above baseline (criterion A, ≥15% above baseline (criterion B; and ≥10% absolute increase in percent predicted FEV1 values (criterion C. Several outcomes (pre-dose spirometry, exacerbations, St. George's Respiratory Questionnaire [SGRQ] total score were assessed according to presence or absence of BDR in the treatment groups. Results 5783 of 5993 randomized patients had evaluable pre- and post-bronchodilator spirometry at baseline. Mean age (SD was 64 (8 years, with 75% men, mean post-bronchodilator FEV1 1.33 ± 0.44 L (47.6 ± 12.7% predicted and 30% current smokers. At baseline, 52%, 66%, and 39% of patients had acute BDR using criterion A, B, and C, respectively. The presence of BDR was variable at follow-up visits. Statistically significant improvements in spirometry and health outcomes occurred with tiotropium regardless of the baseline BDR or criterion used. Conclusions A large proportion of COPD patients demonstrate significant acute BDR. BDR in these patients is variable over time and differs according to the criterion used. BDR status at baseline does not predict long-term response to tiotropium. Assessment of acute BDR should not be used as a decision-making tool when prescribing tiotropium to patients with COPD.

Full Text Available Radiation therapy is a standard treatment in the multidisciplinary approach to the treatment of head and neck carcinomas (HNC. The description and perception of the effects caused by the treatment in the normal tissues is important for the clinical evaluation of the patient because treatment is interrupted if the patient develops several acute side effects which directly affect their survival. This study involved 46 patients over 6 weeks of treatment and evaluated the observed acute effects of treatment in five different anatomical areas - skin, mucosa, salivary glands, pharynx /esophagus and larynx. This evaluation adopted the classification of the Acute Radiation Morbidity Scoring Criteria of the Radiation Therapy Oncology Group (RTOG. Data analysis revealed that the acute effects related to the RapidArcTM technique appeared earlier when compared to IMRT techniques. On the other hand, the IMRT technique showed more exacerbated high-grade effects.

Although psychological stress has long been known to alter cardiovascular function, there have been few studies on the effect of psychological stress on platelets, which play a pivotal role in cardiovascular disease. In the present study, we investigated the effects of acute and chronic psychological stress on the aggregation of platelets and platelet cytosolic free calcium concentration ([Ca(2+)]i). Mice were subjected to both transportation stress (exposure to novel environment, psychological stress) and restraint stress (psychological stress) for 2 h (acute stress) or 3 weeks (2 h/day) (chronic stress). In addition, adrenalectomized mice were subjected to similar chronic stress (both transportation and restraint stress for 3 weeks). The aggregation of platelets from mice and [Ca(2+)]i was determined by light transmission assay and fura-2 fluorescence assay, respectively. Although acute stress had no effect on agonist-induced platelet aggregation, chronic stress enhanced the ability of the platelet agonists thrombin and ADP to stimulate platelet aggregation. However, chronic stress failed to enhance agonist-induced increase in [Ca(2+)]i. Adrenalectomy blocked chronic stress-induced enhancement of platelet aggregation. These results suggest that chronic, but not acute, psychological stress enhances agonist-stimulated platelet aggregation independently of [Ca(2+)]i increase, and the enhancement may be mediated by stress hormones secreted from the adrenal glands.

The health effects of depleted uranium (DU) are mainly caused by its chemical toxicity. Although the kidneys are the main target organs for uranium toxicity, uranium can also reach the brain. In this paper, the central effects of acute exposure to DU were studied in relation to health parameters and the sleep-wake cycle of adult rats. Animals were injected intraperitoneally with 144 ± 10 μg DU kg -1 as nitrate. Three days after injection, the amounts of uranium in the kidneys represented 2.6 μg of DU g -1 of tissue, considered as a sub-nephrotoxic dosage. The central effect of uranium could be seen through a decrease in food intake as early as the first day after exposure and shorter paradoxical sleep 3 days after acute DU exposure (-18% of controls). With a lower dosage of DU (70 ± 8 μg DU kg -1 ), no significant effect was observed on the sleep-wake cycle. The present study intends to illustrate the fact that the brain is a target organ, as are the kidneys, after acute exposure to a moderate dosage of DU. The mechanisms by which uranium causes these early neurophysiological perturbations shall be discussed

The aim of our paper is to analyse the effect of the so-called performance volume limit (PVL) financing method on acute hospital care. The data were derived from the nationwide administrative dataset of the National Health Insurance Fund Administration (OEP) covering the period 2003-2008. We analysed the trends in the DRG cost-weights, number of cases, case-mix, and average length of stay. We calculated the average annual reimbursement rate per DRG cost-weight with and without the application of PVL degression according to the hospital type and medical professions. Our results showed that although the national case mix (i.e., the sum of all of the DRG cost-weights produced in one year) did not change between 2003-2006, the trend of the annual number of cases increased, and the average length of stay decreased. During 2007-2008, a significant decline was found in each indicator. The introduction of the PVL resulted in a health insurance budget saving of 1.9% in 2004, 2.6% in 2005, 3.4% in 2006, 5.6% in 2007, and 3.2% in 2008. We found the lowest reimbursement rate per DRG cost-weight at the university medical schools (HUF 138,200 or € 550) and children's hospitals (HUF 132,547 or € 528), whereas the highest was at the county hospitals (HUF 143,451 or € 571) and city hospitals (HUF 142, 082 or € 565). The implementation of the PVL reduced the acute care hospital activity and reimbursement. The effect of the PVL was different on the different types of hospitals, and it had a serious disadvantageous effect on the university medical schools and children's hospitals.

To explore the occupational backgrounds of English Non-Executive Directors (NED) on Acute National Health Service (NHS) Trusts. Data extrapolated from Trust websites of NED' occupational backgrounds by gender and occupations, and inter-rater reliability test undertaken. Data were available on all but 24 of the 166 Acute Trusts' from all regions. Trust Chairs and NED were categorised by their dominant occupation. Differentiating NED with and without health or social care leadership experience. The ratings of NED' occupations positively correlated (p business' (Francis, 2013) rather than developing a more patient-centred, clinically led and integrated NHS? It is suggested that Boards need more NED with health and social care leadership experience and methods to identify the 'patient's agenda' to create 'a common culture' that places 'patients at the centre of everything we do' (Hunt, 2012). A key context for Trust Boards operations is funding, which Francis' terms of reference excluded, an issue that is briefly discussed.

An important goal of home health care is to assist patients to remain in community living arrangements. Yet home care often fails to prevent hospitalizations and to facilitate discharges to community living, thus putting patients at risk of additional health challenges and increasing care costs. To determine the relationship between home health agency work environments and agency-level rates of acute hospitalization and discharges to community living. Analysis of linked Center for Medicare and Medicaid Services Home Health Compare data and nurse survey data from 118 home health agencies. Robust regression models were used to estimate the effect of work environment ratings on between-agency variation in rates of acute hospitalization and community discharge. Home health agencies with good work environments had lower rates of acute hospitalizations and higher rates of patient discharges to community living arrangements compared with home health agencies with poor work environments. Improved work environments in home health agencies hold promise for optimizing patient outcomes and reducing use of expensive hospital and institutional care.

Suicides among men aged 35-64 years increased by 27% between 1999 and 2013, yet little research exists to examine the nature of the suicide risk within this population. Many men do not seek help if they have mental health problems and suicides may occur in reaction to stressful circumstances. We examined the precipitating circumstances of 600 suicides without known mental health or substance abuse (MH/SA) problems and with a recent crisis. Whether these suicides occurred within the context of an acute crisis only or in the context of chronic circumstances was observed. Using data from the National Violent Death Reporting System and employing mixed-methods analysis, we examined the circumstances and context of a census of middle-aged male suicides (n = 600) in seven states between 2005 and 2010. Precipitating circumstances among this group involved intimate partner problems (IPP; 58.3%), criminal/legal problems (50.7%), job/financial problems (22.5%), and health problems (13.5%). Men with IPP and criminal/legal issues were more likely than men with health and/or job/financial issues to experience suicide in the context of an acute crisis only. Suicides occurring in reaction to an acute crisis only or in the context of acute and chronic circumstances lend themselves to opportunities for intervention. Further implications are discussed.

According to the cross-stressor adaptation hypothesis, physically trained individuals show lower physiological and psychological responses to stressors other than exercise, e.g. psychosocial stress. Reduced stress reactivity may constitute a mechanism of action for the beneficial effects of exercise in maintaining mental health. With regard to neural and psychoneuroendocrine stress responses, the acute stress-buffering effects of exercise have not been investigated yet. A sample of highly trained (HT) and sedentary (SED) young men was randomized to either exercise on a treadmill at moderate intensity (60-70% VO2max; AER) for 30 min, or to perform 30 min of "placebo" exercise (PLAC). 90 min later, an fMRI experiment was conducted using an adapted version of the Montreal Imaging Stress Task (MIST). The subjective and psychoneuroendocrine (cortisol and α-amylase) changes induced by the exercise intervention and the MIST were assessed, as well as neural activations during the MIST. Finally, associations between the different stress responses were analysed. Participants of the AER group showed a significantly reduced cortisol response to the MIST, which was inversely related to the previous exercise-induced α-amylase and cortisol fluctuations. With regard to the sustained BOLD signal, we found higher bilateral hippocampus (Hipp) activity and lower prefrontal cortex (PFC) activity in the AER group. Participants with a higher aerobic fitness showed lower cortisol responses to the MIST. As the Hipp and PFC are brain structures prominently involved in the regulation of the hypothalamus-pituitary-adrenal (HPA) axis, these findings indicate that the acute stress-buffering effect of exercise relies on negative feedback mechanisms. Positive affective changes after exercise appear as important moderators largely accounting for the effects related to physical fitness. Copyright © 2014 Elsevier Ltd. All rights reserved.

Purpose: To study the effect of a dietary intervention on acute gastrointestinal side effects and other aspects of health-related quality of life (HRQOL) in prostate cancer patients referred to radiotherapy. Materials and methods: A total of 130 patients were randomly assigned to one of two groups: an intervention group (IG, n = 64), instructed to reduce their intake of insoluble dietary fibres and lactose, a standard care group (SC, n = 66), instructed to continue their normal diet. Gastrointestinal side effects and other aspects of HRQOL were evaluated from baseline up to 2 months after completed radiotherapy, using the EORTC QLQ-C30 and QLQ-PR25 and the study-specific Gastrointestinal Side Effects Questionnaire (GISEQ). A scale indicating adherence to dietary instructions was developed from a Food Frequency Questionnaire (FFQ), with lower scores representing better compliance. Descriptive and inferential statistical analyses were conducted. Results: There was an interaction effect between randomization and time in the FFQ Scores (p < 0.001), indicating that both groups followed their assigned dietary instructions. The dietary intervention had no effect on gastrointestinal side effects or other aspects of HRQOL. During radiotherapy, the percentage of patients with bowel symptoms and bloated abdomen was lower in IG compared to SC, but the between-group differences were not statistically significant. During radiotherapy, the percentage of patients with bowel symptoms, urinary symptoms, pain, fatigue and diminished physical and role functioning increased in both groups. Conclusions: The dietary intervention had no effect on gastrointestinal side effects or other aspects of HRQOL. The tendency towards lower prevalence of bowel symptoms in IG may indicate some positive effect of the dietary intervention, but methodological refinements, clearer results and longer follow-up are needed before the value of diet change can be established with certainty.

Post-acute care (PAC) service is becoming increasingly important in Taiwan as a core focus of government policies that are designed to ensure continuity of care. In order to improve PAC nursing education and quality of care, the present study applies a modified Delphi method to identify the core competences of nurses who provide PAC services to acute stroke patients. We surveyed 18 experts in post-acute care and long-term care anonymously using a 29-question questionnaire in order to identify the essential professional skills that are required to perform PAC effectively. The results of this survey indicate that the core competences of PAC may be divided into two categories: Case Management and Care Management. Case Management includes Direct Care, Communication, Health Care Education, Nursing Consulting, and Family Assessment & Health Care. Care Management includes Interdisciplinary Teamwork, Patient Care Management, and Resource Integration. The importance and practicality of each item was evaluated using a 7-point Likert scale. The experts required 2 rounds to reach a consensus about the importance and 3 rounds to determine the practicality of PAC core competences. This process highlighted the differing points of view that are held by professionals in the realms of nursing, medicine, and national health policy. The PAC in-job training program in its current form inadequately cul-tivates core competence in Care Management. The results of the present study may be used to inform the development of PAC nurse orientation training programs and continuing education courses.

To investigate the effect of Uncaria rhynchophylla total alkaloids (RTA) pretreatment on the voltage-gated sodium currents of the rat hippocampal neurons after acute hypoxia. Primary cultured hippocampal neurons were divided into RTA pre-treated and non-pretreated groups. Patch clamp whole-cell recording was used to compare the voltage-gated sodium current amplitude and threshold with those before hypoxia. After acute hypoxia, sodium current amplitude was significantly decreased and its threshold was upside. RTA pretreatment could inhibit the reduction of sodium current amplitude. RTA pretreatment alleviates the acute hypoxia-induced change of sodium currents, which may be one of the mechanisms for protective effect of RTA on cells.

In February, 2017, the US Food and Drug Administration approved the blood infection marker procalcitonin for guiding antibiotic therapy in patients with acute respiratory infections. This meta-analysis of patient data from 26 randomised controlled trials was designed to assess safety of procalcitonin-guided treatment in patients with acute respiratory infections from different clinical settings. Based on a prespecified Cochrane protocol, we did a systematic literature search on the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase, and pooled individual patient data from trials in which patients with respiratory infections were randomly assigned to receive antibiotics based on procalcitonin concentrations (procalcitonin-guided group) or control. The coprimary endpoints were 30-day mortality and setting-specific treatment failure. Secondary endpoints were antibiotic use, length of stay, and antibiotic side-effects. We identified 990 records from the literature search, of which 71 articles were assessed for eligibility after exclusion of 919 records. We collected data on 6708 patients from 26 eligible trials in 12 countries. Mortality at 30 days was significantly lower in procalcitonin-guided patients than in control patients (286 [9%] deaths in 3336 procalcitonin-guided patients vs 336 [10%] in 3372 controls; adjusted odds ratio [OR] 0·83 [95% CI 0·70 to 0·99], p=0·037). This mortality benefit was similar across subgroups by setting and type of infection (p interactions >0·05), although mortality was very low in primary care and in patients with acute bronchitis. Procalcitonin guidance was also associated with a 2·4-day reduction in antibiotic exposure (5·7 vs 8·1 days [95% CI -2·71 to -2·15], pacute respiratory infections reduces antibiotic exposure and side-effects, and improves survival. Widespread implementation of procalcitonin protocols in patients with acute respiratory infections thus has the potential to improve antibiotic

Objective(s): Due to the prevalence and pervasiveness of stress in modern life and exposure to both chronic and acute stresses, it is not clear whether prior exposure to chronic stress can influence the impairing effects of acute stress on memory retrieval. This issue was tested in this study. Materials and Methods: Adult male Wistar rats were randomly assigned to the following groups: control, acute, chronic, and chronic + acute stress groups. The rats were trained with six trials per day for 6 consecutive days in the water maze. Following training, the rats were either kept in control conditions or exposed to chronic stress in a restrainer 6 hr/day for 21 days. On day 22, a probe test was done to measure memory retention. Time spent in target and opposite areas, platform location latency, and proximity were used as indices of memory retention. To induce acute stress, 30 min before the probe test, animals received a mild footshock. Results: Stressed animals spent significantly less time in the target quadrant and more time in the opposite quadrant than control animals. Moreover, the stressed animals showed significantly increased platform location latency and proximity as compared with control animals. No significant differences were found in these measures among stress exposure groups. Finally, both chronic and acute stress significantly increased corticosterone levels. Conclusion: Our results indicate that both chronic and acute stress impair memory retrieval similarly. Additionally, the impairing effects of chronic stress on memory retrieval were not influenced by acute stress. PMID:27635201

Pain management remains a critical issue for hospitals and is receiving the attention of hospital accreditation organizations. The acute care setting of the hospital provides an excellent opportunity for the integration of massage therapy for pain management into the team-centered approach of patient care. This preliminary study evaluated the effect of the use of massage therapy on inpatient pain levels in the acute care setting. The study was conducted at Flagstaff Medical Center in Flagstaff, Arizona-a nonprofit community hospital serving a large rural area of northern Arizona. A convenience sample was used to identify research participants. Pain levels before and after massage therapy were recorded using a 0 - 10 visual analog scale. Quantitative and qualitative methods were used for analysis of this descriptive study. Hospital inpatients (n = 53) from medical, surgical, and obstetrics units participated in the current research by each receiving one or more massage therapy sessions averaging 30 minutes each. The number of sessions received depended on the length of the hospital stay. Before massage, the mean pain level recorded by the patients was 5.18 [standard deviation (SD): 2.01]. After massage, the mean pain level was 2.33 (SD: 2.10). The observed reduction in pain was statistically significant: paired samples t(52) = 12.43, r = .67, d = 1.38, p massage therapy into the acute care setting creates overall positive results in the patient's ability to deal with the challenging physical and psychological aspects of their health condition. The study demonstrated not only significant reduction in pain levels, but also the interrelatedness of pain, relaxation, sleep, emotions, recovery, and finally, the healing process.

The objective of this study was to assess the efficacy of paracetamol (acetaminophen) on body temperature in acute stroke. Medline, Cochrane Central Register of Controlled Trials, EMBASE, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, and the World Health Organization (WHO) International Clinical Trials Registry Platform were searched electronically. Relevant journals and references of studies included were hand-searched for randomized controlled trials (RCT) and controlled clinical trials (CCT) regarding the efficacy of paracetamol (acetaminophen) on body temperature in acute stroke. Two reviewers independently performed data extraction and quality assessment. Data were analyzed using RevMan 5.3 software by the Cochrane Collaboration. Five studies were included. To compare the efficacy of paracetamol (acetaminophen) in acute stroke, the pooled RR (Risk Ratio) and its 95% CI of body temperature reduction at 24h from the start of treatment were -0.3 (95% CI: -0.52 to -0.08), with statistical significance (P=0.007). Consistently, the pooled RR (Risk Ratio) and its 95% CI of body temperature at 24h from the start of treatment were -0.22 (-0.29, -0.15), with statistical significance (PParacetamol (acetaminophen) is one of the most commonly used antipyretic drugs and has some capability to reduce body temperature through acting on central nervous system. Acetaminophen showed some capability to decrease body temperature for acute stroke. Acetaminophen could not improve functional outcome and reduce adverse events of patients with acute stroke.

2013-01-01

Full Text Available Tumor necrosis factor-alpha antagonism is an important treatment strategy in patients with rheumatoid arthritis, psoriatic arthritis, vasculitis, and ankylosing spondylitis. Adalimumab is one of the well-known tumor necrosis factor-alpha blocking agents. There are several side effects reported in patients with adalimumab therapy. Cardiac side effects of adalimumab are rare. Only a few cardiac side effects were reported. A 61-year-old man treated with adalimumab for the last 6 months due to psoriatic arthritis presented with typically acute pleuropericarditis. Chest X-ray and echocardiography demonstrated marked pericardial effusion. Patient was successfully evaluated for the etiology of acute pleuro-pericarditis. Every etiology was excluded except the usage of adalimumab. Adalimumab was discontinued, and patient was treated with 1200 mg of ibuprofen daily. Control chest X-ray and echocardiography after three weeks demonstrated complete resolution of both pleural and pericardial effusions. This case clearly demonstrated the acute onset of pericarditis with adalimumab usage. Acute pericarditis and pericardial effusion should be kept in mind in patients with adalimumab treatment.

Recent advances in the treatment of colonic diverticular disease and prevention of acute diverticulitis

Elisei, Walter; Tursi, Antonio

2016-01-01

The incidence of diverticulosis and diverticular disease of the colon is increasing worldwide. Although the majority of patients remains asymptomatic long-life, the prevalence of diverticular disease of the colon, including acute diverticulitis, is substantial and is becoming a significant burden on National Health Systems in terms of direct and indirect costs. Focus is now being drawn on identifying the correct therapeutic approach by testing various treatments. Fiber, non-absorbable antibiotics and probiotics seem to be effective in treating symptomatic and uncomplicated patients, and 5-aminosalicylic acid might help prevent acute diverticulitis. Unfortunately, robust evidence on the effectiveness of a medical strategy to prevent acute diverticulitis recurrence is still lacking. We herein provide a concise review on the effectiveness and future perspectives of these treatments. PMID:26752946

Protocol for an economic evaluation alongside the University Health Network Whiplash Intervention Trial: cost-effectiveness of education and activation, a rehabilitation program, and the legislated standard of care for acute whiplash injury in Ontario

2011-01-01

Background Whiplash injury affects 83% of persons in a traffic collision and leads to whiplash-associated disorders (WAD). A major challenge facing health care decision makers is identifying cost-effective interventions due to lack of economic evidence. Our objective is to compare the cost-effectiveness of: 1) physician-based education and activation, 2) a rehabilitation program developed by Aviva Canada (a group of property and casualty insurance providers), and 3) the legislated standard of care in the Canadian province of Ontario: the Pre-approved Framework Guideline for Whiplash developed by the Financial Services Commission of Ontario. Methods/Design The economic evaluation will use participant-level data from the University Health Network Whiplash Intervention Trial and will be conducted from the societal perspective over the trial's one-year follow-up. Resource use (costs) will include all health care goods and services, and benefits provided during the trial's 1-year follow-up. The primary health effect will be the quality-adjusted life year. We will identify the most cost-effective intervention using the incremental cost-effectiveness ratio and incremental net-benefit. Confidence ellipses and cost-effectiveness acceptability curves will represent uncertainty around these statistics, respectively. A budget impact analysis will assess the total annual impact of replacing the current legislated standard of care with each of the other interventions. An expected value of perfect information will determine the maximum research expenditure Canadian society should be willing to pay for, and inform priority setting in, research of WAD management. Discussion Results will provide health care decision makers with much needed economic evidence on common interventions for acute whiplash management.

Acute Radiation Syndrome (ARS) and its harmful effects on human health

International Nuclear Information System (INIS)

Khanam, Yasmin; Singh, Yogender

2012-01-01

After radiation exposure a series of many clinical syndromes appear that is called as Acute Radiation Syndrome (ARS). ARS also known as radiation toxicology or radiation sickness. Both low and higher doses radiation exposure on human body cause different types of radiation syndromes. These radiations may be ionizing radiations. X-rays and gamma rays etc. some times neutrons or radionuclides may also be deposited in human body and their effective doses cause major injuries or abnormalities even sometimes death also. ARS consist of a sequence of phased symptoms. These symptoms appear after the radiation exposure for several days to several months or sometimes for a long period or years. ARS depends on the quantity of absorbed radiation dose (rad0). ARS is characterized by an initial prodromal stage of malaise, nausea, vomiting, and diarrhea. Critical effects of ARS are Hematologic, that results infections to low white blood cells (WBC), bleeding due to low platelets and anemia due to low red blood cells (RBC), Gastrointestinal results nausea, vomiting, loss of appetite and abdominal pain (exposure doses of 600-1000 rad) and Neurovascular depending on the exposure dose. Neurovascular syndrome typically occurs at exposure doses greater than 1000 rad. It presents with neurological symptoms such as dizziness, headache, or decreased level of consciousness with an absence of vomiting. The clinical course of radiation sickness following a single intensive exposure to whole body radiation is characterized by three successive phases; a prodromal phase, which develops within minutes or hours after exposure, an ensuring latent period, which is relatively asymptomatic; and the main phase of the illness. Complete Blood Count (CBC) are helpful for the diagnosis for ARS. ARS may cause skin damage or loss of epidermis. Person suffering from nausea, vomiting, diarrhea should be admitted to well equipped hospitals or clinics. High exposured persons should be analysed CBC. Their

Oral hygiene and mouth care for older people in acute hospitals: part 1.

Science.gov (United States)

Steel, Ben J

2017-10-31

The oral health of older people in acute hospitals has rarely been studied. Hospital admission provides a prime opportunity for identification and rectification of problems, and oral health promotion. This two-part article explores oral hygiene and mouth care provision for older adults in acute hospitals. The first article presents the findings of a literature review exploring oral and dental disease in older adults, the importance of good oral health and mouth care, and the current situation. Searches of electronic databases and the websites of relevant professional health service bodies in the UK were undertaken to identify articles and guidelines. The literature shows a high prevalence of oro-dental disease in this population, with many known detrimental effects, combined with suboptimal oral hygiene and mouth care provision in acute hospitals. Several guidelines exist, although the emphasis on oral health is weaker than other aspects of hospital care. Older adults admitted to acute hospitals have a high burden of oro-dental disease and oral and mouth care needs, but care provision tends to be suboptimal. The literature is growing, but this area is still relatively neglected. Great potential exists to develop oral and mouth care in this context. The second part of this article explores clinical recommendations. ©2012 RCN Publishing Company Ltd. All rights reserved.

Acute inflammation reduces flow-mediated vasodilatation and increases arterial stiffness in young healthy individuals. However, this response has not been studied in older adults. The aim of this study, therefore, was to evaluate the effect of acute induced systemic inflammation on endothelial function and wave reflection in older adults. Furthermore, an acute bout of moderate-intensity aerobic exercise can be anti-inflammatory. Taken together, we tested the hypothesis that acute moderate-intensity endurance exercise, immediately preceding induced inflammation, would be protective against the negative effects of acute systemic inflammation on vascular function. Fifty-nine healthy volunteers between 55 and 75 years of age were randomized to an exercise or a control group. Both groups received a vaccine (induced inflammation) and sham (saline) injection in a counterbalanced crossover design. Inflammatory markers, endothelial function (flow-mediated vasodilatation) and measures of wave reflection and arterial stiffness were evaluated at baseline and at 24 and 48 h after injections. There were no significant differences in endothelial function and arterial stiffness between the exercise and control group after induced inflammation. The groups were then analysed together, and we found significant differences in the inflammatory markers 24 and 48 h after induction of acute inflammation compared with sham injection. However, flow-mediated vasodilatation, augmentation index normalized for heart rate (AIx75) and β-stiffness did not change significantly. Our results suggest that acute inflammation induced by influenza vaccination did not affect endothelial function in older adults.

Pathogenesis of acute radiation effects in the urinary bladder. Experimental results

Purpose: The present review summarizes experimental studies of the pathogenesis of acute radiation-induced changes in urinary bladder function. Material and methods: Transurethral cystometry was used for longitudinal assessment of bladder function in mice. With this technique, radiation-induced changes in storage capacity can be quantified. In histological studies, changes in urothelial cell density and in urothelial protein expression during the acute radiation response were determined. Acetylsalicylic acid (ASA) was used for the treatment of acute functional changes. Results: The histological studies did not reveal any systematic fluctuations in urothelial cell density during the time of the acute radiation response. However, characteristic changes in the expression of proteins associated with urothelial cell function, differentiation and cell contact were observed, which correlated with the functional impairment. By local or systemical application of ASA, a significant restoration of bladder function compared to placebo treatment could be achieved. Conclusion: Acute functional radiation effects in the urinary bladder are not based on urothelial denudation. However, changes in protein expression indicate an impairment of the urothelial barrier function. The results of ASA treatment demonstrate that prostaglandins are involved in the response. Alterations in urothelial or endothelial prostaglandin metabolism may be primarily radiation-induced or secondary because of the impaired urothelial barrier. (orig.) [de

Ongoing changes to health-care funding Australia wide continue to influence how occupational therapists practise in acute hospitals. This study describes the practice challenges experienced by Western Australian acute care occupational therapists. Then, it explores if and how acute care occupational therapists are modifying their practice in response to these practice changes. This study used a qualitative grounded theory approach. Semi-structured interviews were completed with 13 purposively selected acute care occupational therapists from four Western Australian metropolitan hospitals. Data were analysed using a constant comparative method to provide detailed descriptions of acute care occupational therapy practice and to generate theory. Five conceptual categories were developed. The first two addressed practice challenges: pragmatic organisational influences on client care and establishing a professional identity within the multidisciplinary team. Three categories related to therapist responses are as follows: becoming the client advocate, being the facilitator and applying clinical reasoning. Finally, modified practice was identified as the core category which explains the process whereby acute care occupational therapists are ensuring they remain relevant and authentic in the acute care context. Western Australian acute care occupational therapists are practising in a highly complex health context that presents many challenges. They are responding by using a modified form of practice that ensures occupational therapy skills remain relevant within the narrow confines of this health setting. © 2016 Occupational Therapy Australia.

Full Text Available Purpose: The purpose of our study was to evaluate the effect of oral taurine on the incidence of febrile episodes during chemotherapy in young adults with acute lymphoblastic leukemia. Methods: Forty young adults with acute lymphoblastic leukemia, at the beginning of maintenance course of their chemotherapy, were eligible for this study. The study population was randomized in a double blind manner to receive either taurine or placebo (2 gram per day orally. Life quality and side effects including febrile episodes were assessed using questionnaire. Data were analyzed using Pearson’s Chi square test. Results: Of total forty participants, 43.8% were female and 56.3 % were male. The mean age was 19.16±1.95 years (ranges: 16-23 years. The results indicated that the levels of white blood cells are significantly (P<0.05 increased in taurine treated group. There was no elevation in blasts count. A total of 70 febrile episodes were observed during study, febrile episodes were significantly (P<0.05 lower in taurine patients in comparison to the control ones. Conclusion: The overall incidence of febrile episodes and infectious complications in acute lymphoblastic leukemia patients receiving taurine was lower than placebo group. Taurine’s ability to increase leukocyte count may result in lower febrile episodes.

A Mini-Review on the Effect of Docosahexaenoic Acid (DHA on Cerulein-Induced and Hypertriglyceridemic Acute Pancreatitis

Full Text Available Acute pancreatitis refers to the sudden inflammation of the pancreas. It is associated with premature activation and release of digestive enzymes into the pancreatic interstitium and systemic circulation, resulting in pancreatic tissue autodigestion and multiple organ dysfunction, as well as with increased cytokine production, ultimately leading to deleterious local and systemic effects. Although mechanisms involved in pathogenesis of acute pancreatitis have not been completely elucidated, oxidative stress is regarded as a major risk factor. In human acute pancreatitis, lipid peroxide levels in pancreatic tissues increase. Docosahexaenoic acid (DHA, an omega-3 polyunsaturated fatty acid (C22:6n-3, exerts anti-inflammatory and antioxidant effects on various cells. Previous studies have shown that DHA activates peroxisome proliferator-activated receptor-γ and induces catalase, which inhibits oxidative stress-mediated inflammatory signaling required for cytokine expression in experimental acute pancreatitis using cerulein. Cerulein, a cholecystokinin analog, induces intra-acinar activation of trypsinogen in the pancreas, which results in human acute pancreatitis-like symptoms. Therefore, DHA supplementation may be beneficial for preventing or inhibiting acute pancreatitis development. Since DHA reduces serum triglyceride levels, addition of DHA to lipid-lowering drugs like statins has been investigated to reduce hypertriglyceridemic acute pancreatitis. However, high DHA concentrations increase cytosolic Ca2+, which activates protein kinase C and may induce hyperlipidemic acute pancreatitis. In this review, effect of DHA on cerulein-induced and hypertriglyceridemic acute pancreatitis has been discussed. The relation of high concentration of DHA to hyperlipidemic acute pancreatitis has been included.

In survivors, clinical signs of acute 1080 toxicosis such as salivation and lethar gywere generally very mild. Fasted animals were more prone to 1080 toxicity. In animals that died, more severe signs, including tachypnoea, dyspnoea, and tremors occurred for 15-20 min prior to death. 1080 concentrations were highest in the blood> heart> skeletal muscle> liver. 1080 could not be detected in any of these organs of the animals that survived. Serum citratec oncentratione were elevated for 4 days after dosing. No clinical or biochemical abnormalities were found in any animal after 4 days. Histopathological lesions were most marked in the heart and lung with inflammation, necrosis, and scattered foci of fibrous tissue in the myocardium, pulmonary oedema and inflammation of the lung. No adverse longterm effects on general health or reproductive performance were observed in any sheep that survived the first 4 days following exposure to 1080. The most reliable diagnostic in dicators of 1080 exposure in sheep were measurement of its residues in blood, skeletal muscle and ruminal contents, increased serum citratec oncentratione; l evated heart rate,and characteristic electrocardiograpchh anges(up to 4 days after exposure. Death from 1080 is most likely to occur within 96 h, and animals that survived this period appeared normal.

Full Text Available Background: Low back pain (LBP is one of the most common musculoskeletal complications of today’s societies which, poses a big portion of health expenses and work absentees. Lumbar disc herniation is claimed to be one of the several causes of LBP. Conservative therapies like physiotherapy are found to be beneficial for treatment in such a kind of LBP. However, there is low evidence proving traction therapy can be effective. Therefore, the aim of this study was to evaluate effects of a 7-day physiotherapy protocol along with segmental traction therapy on pain and range of motion in patients with acute LBP Methods: A total of 9 patients with acute LBP voluntarily participated in this study. They undertook a 7-day conventional physiotherapy along with segmental traction therapy. Pain, functional ability and lumbar flexion range of motion (ROM were measured before and after the therapeutic intervention. Results: A significant reduction in pain was observed after the intervention (P=0.006. In addition, patients’ functional ability increased significantly (P=0.03.However, there were no significant changes in lumbar in flexion ROM. Conclusion: According to results of the present study segmental traction therapy along with a physiotherapy protocol consisting of TENS, Ultrasound and Hot pack reduces pain and improves functional ability in patient with acute LBP. Although no effect on lumbar ROM is expected.

Due to poor design, operator error and the absence of an established {sup S}afety Culture{sup ,} the worst accident in the history of nuclear power involving the Unit 4 RMBK reactor occurred at Chernobyl in the Ukraine in the early morning of 26 April 1986. This accident led to the contamination of large tracts of forest and agricultural land (in the former Soviet Union) and the evacuation of a large number of people. Thirty-one people died at the time of the accident or shortly afterwards, and 203 people were treated for the Acute Radiation Syndrome. From about 1990 a significant increase in the number of childhood thyroid cancers has been noted in Belarus and Ukraine. Because of the social, political and economic situation in the Soviet Union soon after the accident, the anxiety and stress induced in the general population has been enhanced to the point where it may well be the single most important indirect health effect of the accident. Contamination outside the former Soviet Union was largely confined to Europe, where it was extremely patchy and variable. Contamination in the rest of the Northern Hemisphere was insignificant. The health effects in the General Population in the Contaminated Regions in the former USSR and Europe, are predicted to be low and not discernible. However, there may be subgroups within, for example, the Liquidators, which if they can be identified and followed, may show adverse health effects. Health effects in the rest of the Northern Hemisphere will be inconsequential. (author) 38 refs., 1 tab., 1 fig.

Methods A total of 69 infants aged 1-24 months with acute bronchiolitis were studied between September 2009 and December 2010. All patients'age, sex, breastfeeding duration, exposure to smoking, history of using vitamin D, symptoms duration, physical examination and laboratory findings were recorded. Bronchiolitis score and predisposing factors that influence the disease process were determined. Thorax ultrasonography was carried out in all patients, who were evaluated on the 3rd and 7th day of the treatment. Results Mean age of patients (43 boys, 26 girls was 11.97 ± 0.69 months (median 11 months. Breastfeeding duration was 8.26 ± 0.56 months (median 8 months. According to bronchiolitis score, 52 patients (75.4% had mild and moderate bronchiolitis and 17 (24.6% had severe bronchiolitis; 34 patients (49.2% had pleural effusion. There was no relation between pleural effusion and symptoms. Frequency of pleural effusion was significantly higher in patients with risk factors. Conclusions This study demonstrated that most of the acute bronchiolitis cases in the infants studied were accompanied by pleural effusion. Pleural effusion in acute bronchiolitis had no effects on prognosis.

Rhabdomyolysis with acute tubular necrosis following occupational inhalation of thinners.

2017-07-01

Thinners are mixtures of organic solvents commonly containing toluene, xylene, acetone, hexane, benzene and methyl isobutyl ketone. This report describes a case of rhabdomyolysis with acute tubular necrosis and renal failure, most likely attributable to toluene, following occupational exposure to thinners while cleaning a steel water tank. These adverse health effects have previously been reported following acute poisoning or intentional inhalation by drug abusers, but rarely in the occupational setting. Poor working conditions, lack of health and safety training and delayed treatment contributed to the onset and severity of the patient's complications. This case emphasizes the need for strict control measures, including adequate ventilation, training on working in confined spaces, appropriate personal protective equipment and emergency rescue procedures in such settings. In addition, rhabdomyolysis, acute tubular necrosis and renal failure should be added to safety data material as possible complications of excessive inhalation of thinners. © The Author 2017.

Flavanoid-rich dark chocolate consumption benefits cardiovascular health, but underlying mechanisms are elusive. We investigated the acute effect of dark chocolate on the reactivity of prothrombotic measures to psychosocial stress. Healthy men aged 20-50 years (mean ± SD: 35.7 ± 8.8) were assigned to a single serving of either 50 g of flavonoid-rich dark chocolate (n=31) or 50 g of optically identical flavonoid-free placebo chocolate (n=34). Two hours after chocolate consumption, both groups underwent an acute standardised psychosocial stress task combining public speaking and mental arithmetic. We determined plasma levels of four stress-responsive prothrombotic measures (i. e., fibrinogen, clotting factor VIII activity, von Willebrand Factor antigen, fibrin D-dimer) prior to chocolate consumption, immediately before and after stress, and at 10 minutes and 20 minutes after stress cessation. We also measured the flavonoid epicatechin, and the catecholamines epinephrine and norepinephrine in plasma. The dark chocolate group showed a significantly attenuated stress reactivity of the hypercoagulability marker D-dimer (F=3.87, p=0.017) relative to the placebo chocolate group. Moreover, the blunted D-dimer stress reactivity related to higher plasma levels of the flavonoid epicatechin assessed before stress (F=3.32, p = 0.031) but not to stress-induced changes in catecholamines (p's=0.35). There were no significant group differences in the other coagulation measures (p's≥0.87). Adjustments for covariates did not alter these findings. In conclusion, our findings indicate that a single consumption of flavonoid-rich dark chocolate blunted the acute prothrombotic response to psychosocial stress, thereby perhaps mitigating the risk of acute coronary syndromes triggered by emotional stress.

BACKGROUND Although concerns surrounding high-dose dextromethorphan (DXM) abuse have recently increased, few studies have examined the acute cognitive effects of high doses of DXM. The aim of this study was to compare the cognitive effects of DXM with those of triazolam and placebo. METHODS Single, acute, oral doses of DXM (100, 200, 300, 400, 500, 600, 700, 800 mg/70 kg), triazolam (0.25, 0.5 mg /70 kg), and placebo were administered p.o. to twelve healthy volunteers with histories of hallucinogen use, under double-blind conditions, using an ascending dose run-up design. Effects on cognitive performance were examined at baseline and after drug administration for up to 6 hours. RESULTS Both triazolam and DXM produced acute impairments in attention, working memory, episodic memory, and metacognition. Impairments observed following doses of 100-300 mg/70 kg DXM were generally smaller in magnitude than those observed after 0.5 mg/70 kg triazolam. Doses of DXM that impaired performance to the same extent as triazolam were in excess of 10-30 times the therapeutic dose of DXM. CONCLUSION The magnitude of the doses required for these effects and the absence of effects on some tasks within the 100-300 mg/70 kg dose range of DXM, speak to the relatively broad therapeutic window of over-the-counter DXM preparations when used appropriately. However, the administration of supratherapeutic doses of DXM resulted in acute cognitive impairments on all tasks that were examined. These findings are likely relevant to cases of high-dose DXM abuse. PMID:22989498

To determine whether racial and ethnic effects on bounce-back risk (ie, movement to settings of higher care intensity within 30 d of hospital discharge) in acute stroke patients vary depending on initial posthospital discharge destination. Retrospective analysis of administrative data. Four hundred twenty-two hospitals, southern/eastern United States. All Medicare beneficiaries 65 years or more with hospitalization for acute ischemic stroke within one of the 422 target hospitals during the years 1999 or 2000 (N=63,679). Not applicable. Adjusted predicted probabilities for discharge to and for bouncing back from each initial discharge site (ie, home, home with home health care, skilled nursing facility [SNF], or rehabilitation center) by race (ie, black, white, and Hispanic). Models included sociodemographics, comorbidities, stroke severity, and length of stay. Blacks and Hispanics were significantly more likely to be discharged to home health care (blacks=21% [95% confidence interval (CI), 19.9-22.8], Hispanic=19% [17.1-21.7] vs whites=16% [15.5-16.8]) and less likely to be discharged to SNFs (blacks=26% [95% CI, 23.6-29.3], Hispanics=28% [25.4-31.6] vs whites=33% [31.8-35.1]) than whites. However, blacks and Hispanics were significantly more likely to bounce back when discharged to SNFs than whites (blacks=26% [95% CI, 24.2-28.6], Hispanics=28% [24-32.6] vs whites=21% [20.3-21.9]). Hispanics had a lower risk of bouncing back when discharged home than either blacks or whites (Hispanics=14% [95% CI, 11.3-17] vs blacks=20% [18.4-22.2], whites=18% [16.8-18.3]). Patients discharged to home health care or rehabilitation centers demonstrated no significant differences in bounce-back risk. Racial/ethnic bounce-back risk differs depending on initial discharge destination. Additional research is needed to fully understand this variation in effect.

To evaluate sleep deprivation and its effects on young physicians in relation to concentration capacity and psychomotor performance. Eighteen physicians aged 26 - 33 years were divided into 2 groups: non-sleep deprived group (with no night work) and sleep deprived group (minimum 12 hour of night work/week). We applied Pittsburgh Sleep Quality Index to screen the presence of sleep pathology and Epworth Sleepiness Scale to evaluate subjective daytime sleepiness; we used actigraphy and sleep diary to assess sleep hygiene and standard sleep-wake cycles. To demonstrate the effects of sleep deprivation, we applied Toulouse-Piéron's test (concentration test) and a battery of three reaction time tasks after the night duty. Sleep deprived group had higher daytime sleepiness on Epworth Sleepiness Scale (p sleep deprivation was higher (p sleep during the period of night duty was 184.2 minutes to sleep deprived group and 397.7 minutes to non-sleep deprived group (p sleep deprived group had more omissions (p Sleep deprived group; in reaction to instruction test the sleep deprived group showed worse perfection index (p sleep deprivation resulting from nocturnal work in medical professions is associated with a reduction in attention and concentration and delayed response to stimuli. This may compromise patient care as well as the physician's health and quality of life. It is essential to study the effects of acute sleep deprivation on the cognitive abilities and performance of health professionals.

Environmental stress such as extremely warm or cold temperature is often considered a challenge to human health and body homeostasis. However, the human body can adapt relatively well to heat and cold environments, and recent studies have also elucidated that particularly heat stress might be even highly beneficial for human health. Consequently, the aim of the present brief review is first to discuss general cardiovascular and other responses to acute heat stress, followed by a review of beneficial effects of Finnish sauna bathing on general and cardiovascular health and mortality as well as dementia and Alzheimer's disease risk. Plausible mechanisms included are improved endothelial and microvascular function, reduced blood pressure and arterial stiffness, and possibly increased angiogenesis in humans, which are likely to mediate the health benefits of sauna bathing. In addition to heat exposure with physiological adaptations, cold stress-induced physiological responses and brown fat activation on health are also discussed. This is important to take into consideration, as sauna bathing is frequently associated with cooling periods in cold(er) environments, but their combination remains poorly investigated. We finally propose, therefore, that possible additive effects of heat- and cold-stress-induced adaptations and effects on health would be worthy of further investigation.

The Effects of Acute Stress on Core Executive Functions: A Meta-Analysis and Comparison with Cortisol

Science.gov (United States)

Shields, Grant S.; Sazma, Matthew A.; Yonelinas, Andrew P.

2016-01-01

Core executive functions such as working memory, inhibition, and cognitive flexibility are integral to daily life. A growing body of research has suggested that acute stress may impair core executive functions. However, there are a number of inconsistencies in the literature, leading to uncertainty about how or even if acute stress influences core executive functions. We addressed this by conducting a meta-analysis of acute stress effects on working memory, inhibition, and cognitive flexibility. We found that stress impaired working memory and cognitive flexibility, whereas it had nuanced effects on inhibition. Many of these effects were moderated by other variables, such as sex. In addition, we compared effects of acute stress on core executive functions to effects of cortisol administration and found some striking differences. Our findings indicate that stress works through mechanisms aside from or in addition to cortisol to produce a state characterized by more reactive processing of salient stimuli but greater control over actions. We conclude by highlighting some important future directions for stress and executive function research. PMID:27371161

Heart failure (HF) is a global public health problem of increasing importance. The association between acute exposure to air pollution and HF has been well established in developed countries, but little evidence was available in developing countries where air pollution levels were much higher. We conducted a time-series study to investigate the short-term association between air pollution and overall emergency ambulance dispatches (EAD) due to HF in Guangzhou, China. Daily data of EAD due to HF from 1 January 2008 to 31 December 2012 were obtained from Guangzhou Emergency Center. We applied the over-dispersed Poisson generalized addictive model to analyze the associations after controlling for the seasonality, day of the week and weather conditions. We identified a total of 3375 EAD for HF. A 10-μg/m(3) increase in the present-day concentrations of particulate matter with an aerodynamic diameter of less than 10 μm, sulfur dioxide and nitrogen dioxide corresponded to increases of 3.54% [95% confidence interval (CI): 1.35%, 5.74%], 5.29% (95% CI: 2.28%, 8.30%) and 4.34% (95% CI: 1.71%, 6.97%) in daily EAD for HF, respectively. The effects of air pollution on acute HF were restricted on the concurrent day and in the cool seasons. Our results provided the first population-based evidence in Mainland China that outdoor air pollution could trigger the exacerbation of HF. Copyright © 2014 Elsevier Ireland Ltd.

2009-04-01

The goal of this investigation was to assess the influence of acute bouts of aerobic versus resistance exercise on the executive control of working memory. Twenty-one young adult participants completed a cardiorespiratory fitness test and maximal strength tests. On subsequent days, task performance measures of reaction time (RT) and accuracy were collected while participants completed a modified Sternberg working memory task before the start of, immediately after, and 30 min after an intervention consisting of 30 min of either resistance or aerobic exercise and a seated rest control. Findings indicated shorter RT immediately and 30 min after acute aerobic exercise relative to the preexercise baseline with no such effects observed after resistance exercise or seated rest. Further, in the aerobic condition, a larger reduction in RT from the baseline occurred during task conditions requiring increased working memory capacity. Again, no effect was observed in the resistance exercise or the seated rest conditions. These data extend the current knowledge base by indicating that acute exercise-induced changes in cognition are disproportionately related to executive control and may be specific to the aerobic exercise domain.

To examine the cost-effectiveness of semi-rigid ankle brace to facilitate return to work following first-time acute ankle sprains. Economic evaluation based on cost-utility analysis. Ankle sprains are a source of morbidity and absenteeism from work, accounting for 15-20% of all sports injuries. Semi-rigid ankle brace and taping are functional treatment interventions used by Musculoskeletal Physiotherapists and Nurses to facilitate return to work following acute ankle sprains. A decision model analysis, based on cost-utility analysis from the perspective of National Health Service was used. The primary outcomes measure was incremental cost-effectiveness ratio, based on quality-adjusted life years. Costs and quality of life data were derived from published literature, while model clinical probabilities were sourced from Musculoskeletal Physiotherapists. The cost and quality adjusted life years gained using semi-rigid ankle brace was £184 and 0.72 respectively. However, the cost and quality adjusted life years gained following taping was £155 and 0.61 respectively. The incremental cost-effectiveness ratio for the semi-rigid brace was £263 per quality adjusted life year. Probabilistic sensitivity analysis showed that ankle brace provided the highest net-benefit, hence the preferred option. Taping is a cheaper intervention compared with ankle brace to facilitate return to work following first-time ankle sprains. However, the incremental cost-effectiveness ratio observed for ankle brace was less than the National Institute for Health and Care Excellence threshold and the intervention had a higher net-benefit, suggesting that it is a cost-effective intervention. Decision-makers may be willing to pay £263 for an additional gain in quality adjusted life year. The findings of this economic evaluation provide justification for the use of semi-rigid ankle brace by Musculoskeletal Physiotherapists and Nurses to facilitate return to work in individuals with first-time ankle

Many epidemiological studies on the health effects of air pollutants have been carried out in regions with major sources such as factories and automobiles. However, the health effects of air pollutants in regions without major sources remain unclear. This study investigated the acute effects of ambient air pollution on pulmonary function among healthy students in an isolated island without major artificial sources of air pollutants. A panel study was conducted of 43 healthy subjects who attended a school in an isolated island in the Seto Inland Sea, Japan. We measured the forced expiratory volume in 1 s (FEV 1 ) and peak expiratory flow (PEF) every morning for about 1 month in May 2014. Ambient concentrations of particulate matter ≤ 2.5 μm in diameter (PM 2.5 ), particulate matter between 2.5 and 10 μm in diameter (PM 10-2.5 ), black carbon (BC), ozone (O 3 ), and nitrogen dioxide (NO 2 ) were measured. The associations between the concentrations of air pollutants and pulmonary function were analyzed using mixed-effects models. A decrease in FEV 1 was significantly associated with BC concentrations (-27.28 mL [95%confidence interval (CI):-54.10,-0.46] for an interquartile range (IQR) increase of 0.23 μg/m 3 ). The decrease in PEF was significantly associated with indoor O 3 concentrations (-8.03 L/min [95% CI:-13.02,-3.03] for an IQR increase of 11 ppb). Among subjects with a history of allergy, an increase in PM 2.5 concentrations was significantly associated with low FEV 1 . In subjects with a history of asthma, an inverse association between the indoor O 3 concentration and pulmonary function was observed. Our results demonstrate that increases in BC and O 3 concentrations have acute effects on the pulmonary function among students in an isolated island without major artificial sources of air pollutants.

The data of the nationwide prospective registry of acute cerebral large vessel occlusion (LVO; RESCUE-Japan Registry) were analyzed to know the effect of edaravone, a free radical scavenger, on clinical outcome at 90 days after onset. In this registry, patients with acute cerebral LVO admitted within 24 h after onset were prospectively registered. The effect of various factors including endovascular treatment (EVT), intravenous recombinant tissue plasminogen activator (IV rt-PA), and other medication including edaravone on favorable outcome (modified Rankin scale 0-1) was analyzed. Of the 1,454 registered patients, 1,442 patients (99.2%) had the information of edaravone were analyzed. In total, edaravone group had more patients with favorable outcome compared to non-edaravone group (22.9% vs. 13.8%, p = 0.0006). Edaravone increased favorable outcome in patients treated with IV rt-PA (29.4% vs. 11.1%, p = 0.0107), but not with EVT (21.2% vs. 13.9%, p = 0.309). Logistic regression analysis revealed that higher National Institutes of Health Stroke Scale (NIHSS) score on admission [odds ratio (OR) 0.875, 95% confidence interval (CI) 0.858-0.894] and advanced age (OR 0.963, 95%CI 0.952-0.975) were significantly related to unfavorable outcome. In contrast, IV rt-PA (OR 2.489, 95%CI 1.867-3.319), EVT (OR 1.375, 95%CI 1.013-1.865), and edaravone (OR 1.483, 95%CI 1.027-2.143) were significantly associated with favorable outcome. This analysis indicated that IV rt-PA, EVT, and edaravone were effective to obtain favorable outcome in patients with acute LVO. Combination IV rt-PA with edaravone was more effective.

While new forms of tobacco, including waterpipe (WP) smoking, continue to gain popularity, limited literature has examined the vascular health consequences. The purpose of the current study was to examine: (i) the acute WP-induced changes in vascular function; (ii) whether acute changes in vascular function are modified by lifestyle behaviors (habitual physical activity, physical fitness). Fifty three (22.7 y, 36% F, 23.4 kg/m(2)) otherwise healthy WP smokers were recruited. Strain-gauge plethysmography was used to measure forearm blood flow, vascular resistance, venous capacitance, and venous outflow at rest and following occlusion. Habitual physical activity was determined using the Arabic version of short-form international physical activity questionnaire, while physical fitness was assessed using the 6 min walk test and handgrip strength. Partial correlations were used to examine the relationships between post-smoking vascular function and lifestyle behaviors, controlling for pre-smoking vascular measures. (i) WP had a small effect on forearm post-occlusion blood flow (d = -0.19), a moderate effect on venous outflow (d = 0.30), and a moderate effect on post-occlusion vascular resistance (d = 0.32). (ii) Total habitual physical activity strongly correlated with resting blood flow (r = 0.50) and moderately with vascular resistance (r = -0.40). Handgrip strength moderately correlated with venous capacitance (r = 0.30) and post-occlusion blood flow (r = 0.30), while 6 min walked distance moderately correlated with resting venous capacitance (r = 0.30). Waterpipe smoking is associated with immediate changes in vascular function, which are exacerbated in individuals with low habitual physical activity and physical fitness levels in young otherwise healthy individuals.

Appropriate oral health care is fundamental for any individual's health. Dental caries is still one of the major public health problems. The most effective way of caries prevention is the use of fluoride. The aim of our research was to review the literature about fluoride toxicity and to inform physicians, dentists and public health specialists whether fluoride use is expedient and safe. Data we used in our review were systematically searched and collected from web pages and documents published from different international institutions. Fluoride occurs naturally in our environment but we consume it in small amounts. Exposure can occur through dietary intake, respiration and fluoride supplements. The most important factor for fluoride presence in alimentation is fluoridated water. Methods, which led to greater fluoride exposure and lowered caries prevalence, are considered to be one of the greatest accomplishments in the 20th century`s public dental health. During pregnancy, the placenta acts as a barrier. The fluoride, therefore, crosses the placenta in low concentrations. Fluoride can be transmitted through the plasma into the mother's milk; however, the concentration is low. The most important action of fluoride is topical, when it is present in the saliva in the appropriate concentration. The most important effect of fluoride on caries incidence is through its role in the process of remineralization and demineralization of tooth enamel. Acute toxicity can occur after ingesting one or more doses of fluoride over a short time period which then leads to poisoning. Today, poisoning is mainly due to unsupervised ingestion of products for dental and oral hygiene and over-fluoridated water. Even though fluoride can be toxic in extremely high concentrations, it`s topical use is safe. The European Academy of Paediatric Dentistry (EAPD) recommends a preventive topical use of fluoride supplements because of their cariostatic effect.

The effects of acute ..gamma.. irradiation on two models of phytocenoses - natural polyphytic grasslands and freshwater phytoplankton communities developed in artificial cultures - have been studied. A retardation of the successional process and a simplification of community structure was observed. This included a reduction in biomass and degree of complexity. A selection favouring weeds and other species which are usually present in young successional stages was also apparent. To a large extent, the overall effects of ..gamma..-radiation depended upon the degree of ecological stability and maturity. Radiation-induced disturbances seemed to be buffered in advanced successional stages. The model of response to ..gamma..- radiation was similar to that produced by other factors of ecological exploitation or perturbation. Synecological parameters such as diversity, similarity and stability were also studied for acute phytocenoses. Low radiation levels produced some clear stimulation effects, the possible significance of which is discussed.

Periodontal disease has been linked to adverse cardiovascular events by unknown mechanisms. C-reactive protein is a systemic marker released during the acute phase of an inflammatory response and is a prognostic marker for cardiovascular disease, with elevated serum levels being reported during periodontal disease. Studies also reported elevated levels of various other acute-phase reactants in periodontal disease. It has been reported extensively in the literature that treatment of periodontal infections can significantly lower serum levels of C-reactive protein. Therefore, an understanding of the relationship between acute-phase response and the progression of periodontal disease and other systemic health complications would have a profound effect on the periodontal treatment strategies. In view of this fact, the present review highlights an overview of acute-phase reactants and their role in periodontal disease. © 2014 Wiley Publishing Asia Pty Ltd.

2015-04-01

Full Text Available Objective: Resveratrol has been shown to exert anti-inflammatory and antioxidant effects, while sodium alginate is a common pharmaceutic adjuvant with antioxidative and immunomodulatory properties. We performed an animal study to investigate the effect of sodium alginate addition to resveratrol on acute gouty arthritis. Methods: Twenty-four SPF Wistar mice were randomized to four groups receiving the combination of sodium alginate and resveratrol, resveratrol alone, colchicine, and placebo, respectively. Acute gouty arthritis was induced by injection of 0.05 ml monosodium urate (MSU solution (25g/mL into ankle joint cavity. IL-1β, CCR5, and CXCL10 levels in both serum and synovial fluid were measured using ELISA. NLRP3 expression in the synovial tissues was measured using western plot. Results: The combination of sodium alginate and resveratrol significantly reduced synovial levels of IL-1β, CCR5, and CXCL10 when compared with colchicines, and all P values were less than 0.0001. The combination of sodium alginate and resveratrol was also superior to resveratrol in terms of both serum levels and synovial levels of IL-1β, CCR5, and CXCL10. In addition, resveratrol, with or without sodium alginate, could reduce NLRP3 expression obviously in the synovial tissues. Conclusion: The combination of sodium alginate and resveratrol has better effect over colchicines in treating MSU-induced acute gouty arthritis.

Resistance to changing practice from pro re nata prescriptions to patient group directions in acute mental health settings.

Science.gov (United States)

Price, O; Baker, J A

2013-09-01

Poor practice associated with pro re nata (PRN) prescriptions in mental health is known to be common and can increase the risk of serious and potentially fatal side effects. A contributing factor to poor practice is the lack of a clear chain of accountability between the decision to prescribe and administer PRN prescriptions. To address this problem, a patient group direction (PGD) for acute behavioural disturbance (lorazepam 0.5-2 mg) and staff training materials were developed. The intention was to replace PRN prescriptions with the PGD in two mental health trusts. One of the potential benefits of this would be the removal of the contribution of PRN to high and combined dose antipsychotic prescriptions. This proposal, however, was met with significant resistance in both trusts and did not replace PRN as a result. A series of interviews and focus groups were conducted with 16 RMNs working in the two trusts, to explore the reasons why the PGD was met with resistance. Senior nurses perceived resistance to be associated with anxieties over increased responsibility for decision making. Junior nurses reported concerns regarding the medicalization of the nursing role, the paperwork associated with the PGD and the training approach used. Future efforts to implement PGDs in mental health settings must carefully consider the methods for engaging effectively with participating organizations, in terms of managing change and completing the necessary groundwork for successful implementation. © 2012 John Wiley & Sons Ltd.

Health consequences of ionizing radiation exposure

Dalci, D.; Dorter, G.; Guclu, I.

2004-01-01

The increasing use of ionizing radiations all over the world induces an ever increasing interest of the professionals as well as of the whole society in health protection and the risk due to these practices. Shortly after its discovery, it was recognized that ionizing radiation can have adverse health effects and knowledge of its detrimental effects has accumulated. The fact that ionizing radiation produces biological damage has been known for many years. The biological effects of ionizing radiation for radiation protection considerations are grouped into two categories: The deterministic and the stochastic ones. Deterministic radiation effects can be clinically diagnosed in the exposed individual and occur when above a certain 'threshold' an appropriately high dose is absorbed in the tissues and organs to cause the death of a large number of cells and consequently to impair tissue or organ functions early after exposure. A clinically observable biological effect (Acute Radiation Syndromes, ARS) that occurs days to months after an acute radiation dose. ARS is a complex of acute injury manifestations that occur after a sufficiently large portion of a person's body is exposed to a high dose of ionizing radiation. Such irradiation initially injures all organs to some extent, but the timing and extent of the injury manifestations depend upon the type, rate, and dose of radiation received. Stochastic radiation effects are the chronic effects of radiation result from relatively low exposure levels delivered over long periods of time. These are sort of effects that might result from occupational exposure, or to the background exposure levels (includes radioactive pollution). Such late effects might be the development of malignant (cancerous) disease and of the hereditary consequences. These effects may be observed many years after the radiation exposure. There is a latent period between the initial radiation exposure and the development of the biological effect. In this

The acute effects of alpha and beta irradiation of mouse skin and the factors affecting the response

1991-01-01

Several problems regarding acute effects of alpha and beta irradiation were investigated in order to clarify protection problems of localised doses to the skin. A study into the acute biological effects of different energy beta emitters and the effects of energy and area on the response showed direct relationships between these criteria for a range of different acute responses with different time courses. Three different types of acute response were found and these are described as 'moist desquamation', 'acute ulceration' and 'acute epidermal necrosis'. An unexpected finding was that the lower energy beta emitter 170 Tm was as efficient at inducing scab formation as the higher energy 90 Sr sources for the same area of exposure. Experiments using 2x4 cm 2 exposures to 224 Cm alpha particles showed that the response to this poorly penetrating radiation was minimal after doses as high as 180 Gy measured at 10 μm into the skin. In comparison, large area exposure to 170 Tm produced areas of prolonged scabbing after doses up to 100 Gy. However, the intensity of the reaction varied between strains. (author)

This study aims to evaluate the relationship of alcohol/drug use and effect severities to the degree of suicidality in acutely admitted psychiatric patients. Both degree of substance dependency and degree of substance-induced syndrome were analyzed. In addition, length of stay, involuntary status, and against medical advice discharge status were determined as they related to these variables. Structured clinical admissions and discharge ratings were gathered from 10,667 consecutive, single-case individual records, from an urban acute care county psychiatric hospital. Data indicate that of the most severely suicidal group, 56% had substance abuse or dependence, 40% were rated as having half or more of their admission syndrome substance induced, and most had nonpsychotic diagnoses. There was an inverse relationship between degree of substance problem and length of stay. Although these patients more commonly left against medical advice, and were readmitted more frequently, they were less likely to be involuntarily committed. A large, potentially lethal, and highly expensive subgroup of patients has been characterized, which might be called the "New Revolving Door acute psychiatric inpatient." This group, which uses the most expensive level of care in the mental health system but is substantially addiction related, poses special challenges for inpatient psychiatric units, addiction treatment providers, and health care planners.

HARMFUL ALGAL BLOOMS IN THE MEDITERRANEAN SEA: EFFECTS ON HUMAN HEALTH.

2013-01-01

Full Text Available A harmful algal bloom (HAB is defined as a bloom that has deleterious effects on plants, animals or humans. Marine algal toxins are responsible for an array of human illnesses associated with consumption of seafood or exposure to aerosolized toxins. The effects of algal toxins are generally observed as acute intoxications, whereas the environmental health effects of chronic exposure to low levels of algal toxins are, to date, only poorly documented and an emerging issue. Consumption of seafood contaminated with algal toxins can result in five types of seafood poisoning syndromes: paralytic shellfish poisoning, neurotoxic shellfish poisoning, amnesic shellfish poisoning, diarrhetic shellfish poisoning and ciguatera fish poisoning. The aim of this paper is to provide an overview on HAB-related issues in the Mediterranean Sea.

New-onset, hospital-acquired anemia (HAA) during acute myocardial infarction (AMI) is independently associated with poor outcomes. The patterns of recovery from HAA after AMI and their association with mortality and health status are unknown. In the prospective 24-center Translational Research Investigating Underlying disparities in acute myocardial infarction Patients' Health Status (TRIUMPH) registry, we identified 530 patients with AMI and HAA (defined as normal hemoglobin at admission with the development of anemia by discharge) who had a repeat, protocol-driven hemoglobin measurement at 1 month after discharge. The 1-month measures were used to define persistent (persistent anemia) and transient (anemia resolved) HAA. The patients' health status was assessed at 1, 6, and 12 months after AMI using the Short-Form 12 Physical Component Summary, and the health status of patients with persistent and transient HAA was compared using multivariate repeated measures regression analysis. Mortality was compared using the log-rank test and proportional hazards regression analysis. Overall, 165 patients (31%) developed persistent HAA. The adjusted mean Short-Form 12 Physical Component Summary scores at the follow-up visit were significantly lower in those with persistent HAA than in those with transient HAA (-2.0 points, 95% confidence interval -3.6 to -0.3; p = 0.02). During a median follow-up of 36 months, the crude mortality (13% vs 5%, p = 0.002) and multivariate-adjusted mortality (hazard ratio 2.08, 95% confidence interval 1.02 to 4.21, p = 0.04) was greater in patients with persistent HAA. In conclusion, HAA persists 1 month after discharge in nearly 1 of 3 patients and is associated with worse health status and greater mortality. Additional investigation is needed to understand whether HAA prevention, recognition, and treatment, particularly among those with persistent HAA, will improve outcomes.

Lechat, M.F.

1984-01-01

In the aftermath of a thermonuclear attack a number of health problems would appear, related to the changed living conditions, lack of food, absence of sanitation, the environmental effects, and disruption of the health services. Internal irradiation by ingestion of radioactive isotopes deposited on the ground would constitute a major hazard from the fallout. In the first few weeks following the attack iodine-131 would present the greatest hazard. Its main entry into the body would be through milk from livestock grazing on pastures contaminated with fallout; milk from local cattle pasturing in open land would thus be unsuitable for consumption. There is much speculation about the possible outbreaks of communicable diseases following a nuclear attack. Infection could emerge as a major problem. It constitutes a leading cause of death in burns. In the Japanese experience acute radiation sickness was generally accompanied by infectious complications

Full Text Available Exercise and physical activity have proven benefits for physical and psychological well-being. However, it is not clear if healthy young adults can enhance mood in everyday life through regular exercise. Earlier studies mainly showed positive effects of acute exercise and exercise programs on psychological well-being in children, older people and in clinical populations. Few studies controlled participants´ physical activity in daily life, performed besides the exercise program, which can impact results. In addition the transition from mood enhancement induced by acute exercise to medium or long-term effects due to regular exercise is not yet determined.The purpose of this pilot study was to examine the acute effects of an aerobic running training on mood and trends in medium term changes of mood in everyday life of young adults. We conducted a 10-week aerobic endurance training with frequent mood assessments and continuous activity monitoring. 23 apprentices, separated into experimental and control group, were monitored over 12 weeks.To control the effectiveness of the aerobic exercise program, participants completed a progressive treadmill test pre and post the intervention period. The three basic mood dimensions energetic arousal, valence and calmness were assessed via electronic diaries. Participants had to rate their mood state frequently on three days a week at five times of measurement within twelve weeks. Participants´ physical activity was assessed with accelerometers. All mood dimensions increased immediately after acute endurance exercise but results were not significant. The highest acute mood change could be observed in valence (p=.07; η2=.27. However, no medium term effects in mood states could be observed after a few weeks of endurance training.Future studies should focus on the interaction between acute and medium term effects of exercise training on mood. The decreasing compliance over the course of the study requires the

Yi-Fu-Qing granule is a traditional Chinese medicine for the treatment of acute respiratory tract infections. The present study sought to investigate the anti-virus effects of Yi-Fu-Qing granule on acute respiratory infections with respiratory syncytial virus (RSV) and human adenoviruses type 3 (Ad3). The cytotoxicity of Yi-Fu-Qing granule was evaluated by the neutral red assay on HeLa cells. The antiviral effect of Yi-Fu-Qing granule was tested by observing the cytopathogenic effect (CPE) with a compound mixture of Isatis leaf as the positive control drug. The results indicated that the highest non-toxicity concentration of Yi-Fu-Qing granule on Hela cells was 1:100. The CPE reduction assay showed that Yi-Fu-Qing granule inhibited RSV and Ad3 replication at a concentration of 1:100. Thus, Yi-Fu-Qing granule may have a significant antivirus effect on acute respiratory tract infections with RSV and Ad3 infections and this could prove useful for further antivirus research on acute respiratory tract infections.

Caffeine is widely used for the treatment of apnea of prematurity (AoP) but whether this effect varies with sex is unknown. To shed some light on this question, we present a summary of data obtained on the effects of caffeine on the respiratory chemoreflexes and apnea frequency in 1- and 12-days old male and female rats. Caffeine was either administered as a single acute injection (10mg/kg, i.p.) or for 10 consecutive days (7.5mg/kg/day between 3 and 12days of life by gavage, simulating its clinical use). Acute caffeine had little effects on breathing in 1-day old male and female rats. In 12-days old female rats caffeine reduced the response to hypercapnia (not hypoxia) compared to males. During the steady state of hypoxia females had a lower frequency of apneas than males, and acute injection of caffeine decreased the frequency of apnea, suppressing the differences between males and females. In 12-days old rats chronic administration of caffeine stimulated basal breathing and decreased the frequency of apnea similarly in males and females. In response to hypoxia, chronic caffeine administration also masked the difference in respiratory frequency between males and females observed in control rats. Female rats had lower frequency of apnea than males with or without caffeine treatment. These observations indicate that sex influences the respiratory responses to caffeine and this effect seems to depend on the modality of administration (acute vs chronic) and environmental oxygen (normoxia vs hypoxia).

This paper reports on the non-participant observational findings from a study, which examined hospital-based nurses' health promoting nursing practice in an acute setting. Nurses are considered to have a key role in health promotion. However, the development of the role of the generalist hospital-based nurse in health promotion has been slow and is not well-understood. The conceptual framework used was based on the Ottawa Charter (WHO 1986). A single qualitative embedded case study, employing data source and methodological triangulation was used. A framework for identifying nurse's use of health promotion methods was developed and used to collect non-participant observations on a purposive sample of eight nurses working on an acute hospital ward. Following the observations a semi structured one-to-one interview was conducted with each observed nurse. One randomly selected patient that the observed nurse had cared for during the observations was also interviewed. Qualitative data analysis based on the work of Miles and Huberman was employed. Two categories were identified 'health promotion strategies and content' and 'patient participation'. The findings indicated that, overall, the strategies used by nurses to promote health were prescriptive and individualistic. The main strategy observed was information giving and the content was 'preparatory information'. Predominantly, nurses practised traditional health education. Overall, patient participation was limited to minor personal aspects of care as nurses focused on the routine and getting the tasks completed. There was no evidence of a ward culture which valued health promotion. Ward managers are key in creating a culture for health promotion. A review of the methods of organizing nursing care is warranted. Nursing programmes must highlight health promotion as integral to practice and emphasis the socio-political dimensions of health promotion.

1. It has been suggested that the high prevalence of drug abuse in schizophrenics is related to chronic treatment with typical neuroleptics and dopaminergic supersensitivity that develops as a consequence. Within this context, atypical neuroleptics do not seem to induce this phenomenon. In the present study, we investigated the effects of acute administration or withdrawal from long-term administration of haloperidol and/or ziprasidone on morphine-induced open-field behaviour in mice. 2. In the first experiment, mice were given a single injection of haloperidol (1 mg/kg, i.p.) or several doses of ziprasidone (2, 4 or 6 mg/kg, i.p.) and motor activity was quantified by the open-field test. The aim of the second experiment was to verify the effects of an acute injection of haloperidol (1 mg/kg) or ziprasidone (6 mg/kg) on 20 mg/kg morphine-induced behaviours in the open-field test. In the third experiment, mice were treated with 1 mg/kg haloperidol and/or 2, 4 or 6 mg/kg ziprasidone for 20 days. Seventy-two hours after the last injection, mice were injected with 20 mg/kg, i.p., morphine and then subjected to the open-field test. Acute haloperidol or ziprasidone decreased spontaneous general activity and abolished morphine-induced locomotor stimulation. 3. Withdrawal from haloperidol or ziprasidone did not modify morphine-elicited behaviours in the open-field test. The results suggest that withdrawal from neuroleptic treatments does not contribute to the acute effect of morphine in schizophrenic patients. © 2014 Wiley Publishing Asia Pty Ltd.

Full Text Available Objective. Right heart catheterization is performed in patients with pulmonary arterial hypertension to determine the severity of disease and their pulmonary vascular reactivity. The acute pulmonary vascular effect of inhaled nitric oxide is frequently used to identify patients who will respond favorably to vasodilator therapy. This study sought to determine whether the acute pulmonary vascular effects of oxygen with nitric oxide and intravenous sildenafil are similar. Methods. A retrospective, descriptive study of 13 individuals with pulmonary hypertension who underwent heart catheterization and acute vasodilator testing was performed. The hemodynamic measurements during five phases (21% to 53% oxygen, 100% oxygen, 100% oxygen with 20 ppm nitric oxide, 21% to 51% oxygen, and 21% to 51% oxygen with 0.05 mg/kg to 0.29 mg/kg intravenous sildenafil of the procedures were compared.Results. Mean pulmonary arterial pressure and pulmonary vascular resistance acutely decreased with 100% oxygen with nitric oxide, and 21% to 51% oxygen with sildenafil. Mean pulmonary arterial pressure (mm Hg, mean ± standard error of the mean was 38 ± 4 during 21% to 53% oxygen, 32 ± 3 during 100% oxygen, 29 ± 2 during 100% oxygen with nitric oxide, 37 ± 3 during 21% to 51% oxygen, and 32 ± 2 during 21% to 51% oxygen with sildenafil. There was not a significant correlation between the percent change in pulmonary vascular resistance from baseline with oxygen and nitric oxide, and from baseline with sildenafil (r2 = 0.011, p = 0.738. Conclusions. Oxygen with nitric oxide and sildenafil decreased pulmonary vascular resistance. However, the pulmonary vascular effects of oxygen and nitric oxide cannot be used to predict the acute response to sildenafil. Additional studies are needed to determine whether the acute response to sildenafil can be used to predict the long-term response to treatment with an oral phosphodiesterase V inhibitor.

Full Text Available Background: Acute pesticide poisoning (APP is commonly underdiagnosed in Tanzania. Studies in developing countries suggest that a lack of diagnostic skills among health care providers (HCPs undermines surveillance for APP. This study aimed at characterizing experience and skills of Tanzanian HCPs regarding APP diagnosis and management. Methodology: The population included HCPs responsible for managing APP in Kilimanjaro and Arusha regions (n = 91. The resulting sample included 66 respondents (response rate: 73%. The data were collected in 2005 using a standardized questionnaire. Results: Half of all respondents (50% reported handling at least 1 APP case with 15% reporting handling more than 5 cases in the past. Reported experience of handling an APP case was marginally higher in respondents who reported ⩾4 years of work experience in the health sector compared with those with <4 years of work experience (odds ratio = 1.32; 95% confidence interval = 0.9-1.5. Most of the respondents had high knowledge of exposure routes, reporting awareness of oral (98.5%, inhalational (93.9%, and dermal (77% routes. The study revealed low awareness of pesticide classification by chemical groups (29% or World Health Organization hazard (0% and weak knowledge on pesticide label instructions (55%. Organophosphates accounted for 35% of the pesticide products reported by respondents as being responsible for poisoning. Some treatment options were incorrectly reported as first aid options, and some reported first aid options were wrong or inappropriate. Conclusions: The study revealed that HCPs in northern Tanzania lack adequate skills to diagnose and manage APP. For effective surveillance of APP, there is a need to include training on hazards, classification, diagnosis, and health effects in the training programmes for all HCPs in Tanzania.

The World Health Organisation called for research assessing the safety of electronic cigarette (e-cigarette). We evaluated the acute effect of active and passive e-cigarette and tobacco cigarette smoking on complete blood count (CBC) markers in 15 smokers and 15 never-smokers, respectively. Smokers underwent a control session, an active tobacco cigarette smoking session, and an active e-cigarette smoking session. Never-smokers underwent a control session, a passive tobacco cigarette smoking session, and a passive e-cigarette smoking session. The results demonstrated that CBC indices remained unchanged during the control session and the active and passive e-cigarette smoking sessions (P>0.05). Active and passive tobacco cigarette smoking increased white blood cell, lymphocyte, and granulocyte counts for at least one hour in smokers and never smokers (Pissues and other areas of consumer product safety of e-cigarettes, because the nicotine content in the liquids used may vary considerably.

In some countries, conditional cash transfer (CCT) programmes show an impact on maternal and child health. Juntos, the CCT programme in Peru, has been evaluated several times operationally, but seldom for maternal and child health outcomes. The objective of this study is to evaluate the impact of Juntos on children under 6 years, pregnant women and mothers of children under 17 years. Outcomes evaluated included (1) anaemia in women and children; (2) acute malnutrition in children; (3) post-partum complications in mothers; and (4) underweight and overweight in mothers. We identified Juntos eligible respondents from the Demographic and Health Surveys of Peru for years 2007 to 2013. Propensity score matching was used to identify comparable treatment and control groups, including eligible respondents enrolled in Juntos vs. those not enrolled in Juntos (individual-level analysis), as well as eligible respondents living in Juntos districts vs. those not residing in Juntos districts (district-level analysis). We then used generalized linear models to estimate prevalence ratios. Individual level analysis showed that Juntos reduced underweight in women (PR:0.39, 95%CI:0.18 - 0.85) and anaemia in children (PR:0.93, 95%CI:0.86 - 1.00). In the district level analysis, the programme was associated with a reduction of overweight in women (PR:0.94, 95%CI:0.90 - 0.98) and acute malnutrition in children (PR:0.49, 95%CI:0.32 - 0.73), but an increase in the prevalence of anaemia in children (PR:1.09, 95%CI:1.01 - 1.17). We found that Juntos had an effect on maternal and child health indicators, but further studies are required to overcome some limitations encountered here. © 2016 John Wiley & Sons Ltd.

Severe acute malnutrition (SAM) in children is the most serious form of malnutrition and is associated with very high rates of morbidity and mortality. For sustainable SAM management, United Nations recommends integration of community based management of acute malnutrition (CMAM) into the health system. The objective of the study was to assess the preparedness of the health system to implement CMAM in Bangladesh. The assessment was undertaken during January to May 2014 by conducting document review, key informant interviews, and direct observation. A total of 38 key informant interviews were conducted among government policy makers and program managers (n = 4), nutrition experts (n = 2), health and nutrition implementing partners (n = 2), development partner (n = 1), government health system staff (n = 5), government front line field workers (n = 22), and community members (n = 2). The assessment was based on: workforce, service delivery, financing, governance, information system, medical supplies, and the broad socio-political context. The government of Bangladesh has developed inpatient and outpatient guidelines for the management of SAM. There are cadres of community health workers of government and non-government actors who can be adequately trained to conduct CMAM. Inpatient management of SAM is available in 288 facilities across the country. However, only 2.7% doctors and 3.3% auxiliary staff are trained on facility based management of SAM. In functional facilities, uninterrupted supply of medicines and therapeutic diet are not available. There is resistance and disagreement among nutrition stakeholders regarding import or local production of ready-to-use therapeutic food (RUTF). Nutrition coordination is fragile and there is no functional supra-ministerial coordination platform for multi-sectoral and multi-stakeholder nutrition. There is an enabling environment for CMAM intervention in Bangladesh although health system

Probiotics may improve a person's health by regulating their immune function. Some trials have shown that probiotic strains can prevent respiratory infections. Even though the previous version of our review showed benefits of probiotics for acute upper respiratory tract infections (URTIs), several new studies have been published. To assess the effectiveness and safety of probiotics (any specified strain or dose), compared with placebo, in the prevention of acute URTIs in people of all ages, at risk of acute URTIs. We searched CENTRAL (2014, Issue 6), MEDLINE (1950 to July week 3, 2014), EMBASE (1974 to July 2014), Web of Science (1900 to July 2014), the Chinese Biomedical Literature Database, which includes the China Biological Medicine Database (from 1978 to July 2014), the Chinese Medicine Popular Science Literature Database (from 2000 to July 2014) and the Masters Degree Dissertation of Beijing Union Medical College Database (from 1981 to July 2014). We also searched the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov for completed and ongoing trials on 31 July 2014. Randomised controlled trials (RCTs) comparing probiotics with placebo to prevent acute URTIs. Two review authors independently assessed the eligibility and quality of trials, and extracted data using the standard methodological procedures expected by The Cochrane Collaboration. We included 13 RCTs, although we could only extract data to meta-analyse 12 trials, which involved 3720 participants including children, adults (aged around 40 years) and older people. We found that probiotics were better than placebo when measuring the number of participants experiencing episodes of acute URTI (at least one episode: odds ratio (OR) 0.53; 95% confidence interval (CI) 0.37 to 0.76, P value school absence (OR 0.10; 95% CI 0.02 to 0.47, very low quality evidence).

Non-ST elevation acute coronary syndrome (NSTE-ACS) imposes a significant health and economic burden on a society. Anticoagulants are recommended as standard therapy by various clinical practice guidelines. Fondaparinux was introduced and evaluated in a number of large randomised, controlled trials. This study therefore aimed to determine the cost-effectiveness of fondaparinux versus enoxaparin in the treatment of NSTE-ACS in Thailand. A two-part construct model comprising a one-year decision tree and a Markov model was developed to capture short and long-term costs and outcomes from the perspective of provider and society. Effectiveness data were derived from OASIS-5 trial while bleeding rates were derived from the Thai Acute Coronary Syndrome Registry (TACSR). Costs data were based on a Thai database and presented in the year of 2013. Both costs and outcomes were discounted by 3% annually. A series of sensitivity analyses were performed. The results showed that compared with enoxaparin, fondaparinux was a cost-saving strategy (lower cost with slightly higher effectiveness). Cost of revascularisation with major bleeding had a greater impact on the amount of cost saved both from societal and provider perspectives. With a threshold of 160,000 THB ((4,857.3 USD) per QALY in Thailand, fondaparinux was about 99% more cost-effective compared with enoxaparin. Fondaparinux should be considered as a cost-effective alternative when compared to enoxaparin for NSTE-ACS based on Thailand's context, especially in the era of limited healthcare resources.

The objective of the study is to assess the cost-effectiveness and cost-utility analysis of a multidisciplinary biopsychosocial educational group intervention (MBEGI of non-specific sub-acute LBP in comparison with the usual care in the working population recruited in primary healthcare centres. Methods/design The study design is a cost-effectiveness and cost-utility analysis of a MBEGI in comparison with the usual care of non-specific sub-acute LBP. Measures on effectiveness and costs of both interventions will be obtained from a cluster randomised controlled clinical trial carried out in 38 Catalan primary health care centres, enrolling 932 patients between 18 and 65 years old with a diagnosis of non-specific sub-acute LBP. Effectiveness measures are: pharmaceutical treatments, work sick leave (% and duration in days, Roland Morris disability, McGill pain intensity, Fear Avoidance Beliefs (FAB and Golberg Questionnaires. Utility measures will be calculated from the SF-12. The analysis will be performed from a social perspective. The temporal horizon is at 3 months (change to chronic LBP and 12 months (evaluate the outcomes at long term. Assessment of outcomes will be blinded and will follow the intention-to-treat principle. Discussion We hope to demonstrate the cost-effectiveness and cost-utility of MBEGI, see an improvement in the patients' quality of life, achieve a reduction in the duration of episodes and the chronicity of non-specific low back pain, and be able to report a decrease in the social costs. If the intervention is cost-effectiveness and cost-utility, it could be applied to Primary Health Care Centres. Trial registration ISRCTN: ISRCTN58719694

Full Text Available Objective: To assess the cost-effectiveness relationship of Ticagrelor versus Clopidogrel for the management of acute coronary syndrome in Spain. Methods: The data from the PLATO study were used for the calculation of the events rate and health-related quality of life for Ticagrelor and Clopidogrel for the first 12 months, whereas the costs were obtained from Spanish sources. Quality of lifeadjusted survival and costs were estimated according to the fact that the patients did not suffer any thrombotic event (myocardial infarction or ictus or this one was not fatal. The lifetime cots, life years gained, and the quality of life-adjusted survival were estimated for both treatment arms. Incremental costeffectiveness ratios were assessed through the perspective of the Spanish healthcare system for 2013, by using a macro-costs strategy based on published literature and the survival tables for the Spanish population. Results: Treatment with Ticagrelor was associated to an incremental cost of 1,228 per year, an increase in 0.1652 life years gained, and 0.1365 years adjusted by quality of life, as compared to Clopidogrel. The cost for one quality of life-adjusted life year was 8,997 and the cost per one gained life year of 7,435 . The sensitivity analysis showed consistent results. Conclusions: Treatment of acute coronary syndrome for 12 months with Ticagrelor was associated with a cost per 1 life year of quality of life-adjusted cost below the cost-effectiveness limits generally accepted in Spain.

This was a cross-sectional study within Brazil's Project for the Expansion and Consolidation of Family Health, 2005, with the objective of universal and free access to the medication prescribed in the last medical appointment for acute health problems and to estimate the degree to which access may have improved with inclusion of the medicines in prevailing policies and programs. The sample included 4,060 adults living in the area of primary health care units in 41 municipalities in South and Northeast Brazil. Access was greater in the South (83.2%) than in the Northeast (71%), and free access was similar (37%), with a greater share by the Family Health Program (FHP) when compared to the traditional model, especially in the Northeast. Some 60% of prescribed medicines and 50% of those on the National List of Essential Medicines (RENAME) were paid for. No variation was observed in the proportion of medicines present on the prevailing RENAME list and access. However, 40% of the medicines that were paid for can currently be obtained through the Popular Pharmacy Program. The latter program appears to emerge as a new way to guarantee access to medicines prescribed in the health system.

As required or pro re nata (PRN) psychotropic medicines are frequently used in acute mental health wards. PRN is known to contribute to polypharmacy and high doses of antipsychotic medication. Few studies have attempted to improve clinician's use of these potentially harmful drugs. The objectives of the study were to determine the impact and acceptability of a good practice manual on prescribing and administration practices of PRN psychotropic medication in acute mental health wards. The study used a pre-post exploratory design with two acute mental health wards in the NW of England. Over the total trial period of 10 weeks, 28 of 35 patients received 484 doses of PRN. Patients had a mean of 3.6 prescriptions of 14 different PRN medications in 34 different dose combinations prescribed. Medication errors beyond poor quality of prescribing occurred in 23 of the 35 patients (65.7%). Prescription quality improved following the introduction of the intervention but quality of nursing notes reduced. Acceptability of the manual to both nursing and medical staff was high. The introduction of the manual appeared to influence some of the practices associated with the prescribing and administration of PRN psychotropic medications. Further, larger, more robust studies are required in this area. In particular research is required to identify the reasons why professionals continue to rely so heavily on using PRN medication.

In recent decades, noise pollution caused by industrialization and increased motorization has become a major concern around the world because of its adverse effects on human well-being. Therefore, transportation agencies have been implementing noise abatement measures in order to reduce road traffic noise. However, limited attention is given to noise in environmental assessment of road transportation systems. This paper presents a framework for a health impact assessment model for road transportation noise emissions. The model allows noise impacts to be addressed with the health effects of air pollutant and greenhouse gas emissions from road transportation. The health damages assessed in the model include annoyance, sleep disturbance, and cardiovascular disease in terms of acute myocardial infarction. The model was applied in a case study in Istanbul in order to evaluate the change in health risks from the implementation of noise abatement strategies. The noise abatement strategies evaluated include altering pavement surfaces in order to absorb noise and introducing speed limits. It was shown that significant improvements in health risks can be achieved using open graded pavement surfaces and introducing speed limits on highways. - Highlights: • Transportation noise has a significant effect on health. • Noise should be included in the environmental assessment of transportation systems. • Traffic noise abatement measures include noise reducing pavements and speed limits. • Noise abatement measures help reduce the health risks of transportation noise. • Speed limit reduction on uncongested roads is an effective way to reduce health risks.

Anxiety disorders, such as post-traumatic stress disorder (PTSD), may be related to an inability to distinguish safe versus threatening environments and to extinguish fear memories. Given the high rate of cigarette smoking in patients with PTSD, as well as the recent finding that an acute dose of nicotine impairs extinction of contextual fear memory, we conducted a series of experiments to investigate the effect of acute nicotine in an animal model of contextual safety discrimination. Following saline or nicotine (at 0.0275, 0.045, 0.09 and 0.18 mg/kg) administration, C57BL/6J mice were trained in a contextual discrimination paradigm, in which the subjects received presentations of conditioned stimuli (CS) that co-terminated with a foot-shock in one context (context A (CXA)) and only CS presentations without foot-shock in a different context (context B (CXB)). Therefore, CXA was designated as the 'dangerous context', whereas CXB was designated as the 'safe context'. Our results suggested that saline-treated animals showed a strong discrimination between dangerous and safe contexts, while acute nicotine dose-dependently impaired contextual safety discrimination (Experiment 1). Furthermore, our results demonstrate that nicotine-induced impairment of contextual safety discrimination learning was not a result of increased generalized freezing (Experiment 2) or contingent on the common CS presentations in both contexts (Experiment 3). Finally, our results show that increasing the temporal gap between CXA and CXB during training abolished the impairing effects of nicotine (Experiment 4). The findings of this study may help link nicotine exposure to the safety learning deficits seen in anxiety disorder and PTSD patients. © The Author(s) 2014.

Full Text Available Background. Acute promyelocytic leukemia is characterized by t(15;17. This leads to the formation of PML/RARα which blocks the differentiation of blasts at the stage of promyelocytes. This is reversed by all-trans-retinoic acid (ATRA, a vitamin A derivative. Acute myocardial ischemia is a rare side effect of ATRA. Case Report. We report a case of acute coronary syndrome manifesting as an adverse effect of ATRA in a lady with APL who had no other risk factors for cardiovascular disease. Conclusions. We emphasize the need for high index of suspicion for the diagnosis of this entity. In the light of this case, the rare instances of ATRA associated acute myocardial ischemia recorded in the literature and the options available for treatment of acute promyelocytic leukemia sans ATRA have been reviewed.

Despite extensive research and clinical efforts made in the management of acute pancre-atitis during the past few decades, to date no effective cure is available and the mortality from severe acute pancre-atitis remains high. Given that lung is the primary cause of early death in acute pancreatitis patients, novel therapeutic approaches aiming to prevent lung injury have become a subject of intensive investigation. In a previous study, we demonstrated that sivelestat, a specific inhibitor of neutrophil elastase, is effective in protecting against lung failure in rats with taurocholate-induced acute pancreatitis. As part of the analyses extended from that study, the present study aimed to evaluate the role of sivelestat and/or resveratrol in the protection against acute pancreatitis-associated lung injury. The extended analyses demonstrated the following: (1) sodium taurocholate induced apparent lung injury and dysfunction manifested by histological anomalies, including vacuolization and apoptosis of the cells in the lung, as well as biochemical aberrations in the blood (an increase in amylase concentration and a decrease in partial arterial oxygen pressure) and increases in activities of reactive oxygen species, interleukin 6, myeloperoxidase, neutrophil elastase, lung edema, bronchotracho alveolar lavage protein concentration, and bronchotracho alveolar lavage cell infiltration in the lung; and (2) in lung tissues, either sivelestat or resveratrol treatment effectively attenuated the taurocholate-induced abnormalities in all parameters analyzed except for serum amylase concentration. In addition, combined treatment with both sivelestat and resveratrol demonstrated additive protective effects on pancreatitis-associated lung injury compared with single treatment.

Full Text Available 2,5-dimethoxy-4-bromophenethylamine (2C-B is a psychedelic phenylethylamine derivative, structurally similar to mescaline. It is a serotonin 5-hydroxytryptamine-2A (5-HT2A, 5-hydroxytryptamine-2B (5-HT2B, and 5-hydroxytryptamine-2C (5-HT2C receptor partial agonist used recreationally as a new psychoactive substance. It has been reported that 2C-B induces mild psychedelic effects, although its acute pharmacological effects and pharmacokinetics have not yet been fully studied in humans. An observational study was conducted to assess the acute subjective and physiological effects, as well as pharmacokinetics of 2C-B. Sixteen healthy, experienced drug users self-administered an oral dose of 2C-B (10, 15, or 20 mg. Vital signs (blood pressure and heart rate were measured at baseline 1, 2, 3, 4, and 6 hours (h. Each participant completed subjective effects using three rating scales: the visual analog scale (VAS, the Addiction Research Centre Inventory (ARCI, and the Evaluation of the Subjective Effects of Substances with Abuse Potential (VESSPA-SSE at baseline, 2–3 and 6 h after self-administration (maximum effects along 6 h, and the Hallucinogenic Rating Scale (maximum effects along 6 h. Oral fluid (saliva was collected to assess 2C-B and cortisol concentrations during 24 h. Acute administration of 2C-B increased blood pressure and heart rate. Scores of scales related to euphoria increased (high, liking, and stimulated, and changes in perceptions (distances, colors, shapes, and lights and different body feelings/surrounding were produced. Mild hallucinating effects were described in five subjects. Maximum concentrations of 2C-B and cortisol were reached at 1 and 3 h after self-administration, respectively. Oral 2C-B at recreational doses induces a constellation of psychedelic/psychostimulant-like effects similar to those associated with serotonin-acting drugs.

Assessment of acute and late effects to high-LET radiation

We have begun to reassess late tissue effects available from the Charged Particle Cancer Radiotherapy program at Berkeley. Our quantitative approach is limited in the analysis of these Phase I/II studies by not having equivalent patient numbers for each of the particle beams studied, by not having completely comparable follow-up times, by variations in the sizes of the fields compared, by variations in the skin scoring photographic documentation available from the patient charts, and by variations in the fractionation sizes, numbers and schedules. Despite these limitations, preliminary evidence demonstrates acute skin reactions with a shift to increasing lower dose per fraction per field for the maximum skin reactions of helium, carbon and neon ions compared to electrons. Comparisons with skin reactions from low-energy neutrons indicate that Bragg peak carbon ions (initial energy 308 MeV/nucleon) are slightly less effective than 7.5 MeV neutrons. Bragg peak neon ions (initial energy 670 MeV/nucleon) corrected for differences in reference radiation are slightly more effective than 7.5 MeV neutrons. Bragg peak silicon (initial energy 670 MeV/nucleon) result in an enhanced acute skin reaction, and a premature appearance of late effects that may indicate a significantly different mechanism of damage and/or repair

Full Text Available Objective. To identify the role of thrombolytic therapy in acute embolic stroke due to infective endocarditis. Design. Case report. Setting. University hospital. Patient. A 70-year-old male presented with acute onset aphasia and hemiparesis due to infective endocarditis. His head computerized tomographic scan revealed left parietal sulcal effacement. He was given intravenous tissue plasminogen activator with significant resolution of the neurologic deficits without complications. Main Outcome Measures. Physical examination, National Institute of Health Stroke Scale, radiologic examination results. Conclusions. Thrombolytic therapy in selected cases of stroke due to infective endocarditis manifesting as major neurologic deficits can be considered as an option after careful consideration of risks and benefits. The basis for such favorable response rests in the presence of fibrin as a major constituent of the vegetation. The risk of precipitating hemorrhage with thrombolytic therapy especially with large infarcts and mycotic aneurysms should be weighed against the benefits of averting a major neurologic deficit.

2015-09-01

Full Text Available Aims: It is internationally recognised that exercise is beneficial—both physically and mentally. However, only a minority of published research has explored the unique contribution of the exercise task itself. We tested the effect an ‘acute bout of moderate exercise’ had on selective attention, executive function and mood. We hypothesised that acute exercise would improve mood and cognitive performance compared to the controls. Method: 29 females and 11 males aged between 18-50 (M=26.5, SD=8.8 were administered the Stroop Colour-Interference Test, Erikson Flanker Task and Positive and Negative Affect Scale (PANAS.  Participants were randomly assigned to one of two conditions (exercise or relaxation. The experimental group (N=20 performed 20 minutes of exercise on a treadmill. The control group (N=20 relaxed for 20 minutes. Measures were taken before and after the intervention. Results: An independent samples t-test compared the differences between post-test and pre-test for the two groups. Results revealed a significant difference between the exercise group and control group on the measures of mood. The exercise group reported increased positive affect (t(38 = 3.10, p = .004, d = .99 and decreased negative affect (t(38 = -3.24, p = .003, d = 1.0 on the post-test. No significant differences between the exercise and control groups were obtained for the two tasks of cognitive performance. Conclusions: A significant difference in the PANAS ratings following exercise offers strong support to earlier research demonstrating that acute exercise improves mood. Although no significant improvement in performance was observed in the two cognitive tasks following acute exercise, it is possible that fitness levels could be the relevant factor, rather than acute exercise as a task. Our findings did not support the hypothesis that acute exercise improves cognitive performance.

Objective: To evaluate the effect of recombinant human epidermal growth factor (Gene Time) on acute mucositis and dermatitis induced by radiation. Methods: 120 head and neck cancer patients were randomized into 3 groups: 1. Mucositis prophylactic application (MPA) group with control, 2. Mucositis therapeutic application (MTA) group with control and 3. Dermatitis therapeutic application (DTA) group with control. Prophylactic application of drug consisted of spraying the Gene Time preparation on the irradiated skin or mucous membrane as radiotherapy was being carried out. This was compared with control patients who received routine conventional skin care. Therapeutic application was started as grade I radiation mucositis or dermatitis appeared. The evaluation of acute radiation mucositis and dermatitis was done according to the systems proposed by RTOG or EORTC. Results: The results showed that in the MPA group, the rate of radiation mucositis at ≤10 Gy was 20% (4/20) as compared to the 70% (14/20) of the control (P = 0.004). During the course of radiation, the incidences of grade III, IV acute radiation mucositis and dermatitis were always lower than the control. In therapeutic application of Gene Time, the response rate of acute radiation mucositis was also better than the control (90% vs 50%) (P = 0.016) and that of acute dermatitis was similar (95% vs 50%) (P = 0.005). Moreover, the ≤3 d rate of healing of grade III dermatitis in the application group was 3/7 as compared to the 0/14 of the control. Conclusion: Prophylactic application of recombinant human epidermal growth factor is able to postpone the development of radiation mucositis. This preparation is also able to lower the incidence of grade III, IV mucositis and dermatitis both by therapeutic and prophylactic application in addition to the hastened healing of grade III dermatitis

Recent surveys carried out in Japan in connection with the reassessment of the dosimetry for long-term effects provided an opportunity for another look at the acute effects of radiation and a recalculation of the LD-50 value. The recalculation gave an LD-50 value which is two to three times lower than had been assumed before. It means that in a nuclear war the number of fatalities due to exposure to radiation would be considerably higher than thought hitherto. 11 refs, 5 figs, 2 tabs

Full Text Available Recognizing patients at a higher risk of developing chronic low back pain (LBP is important in industrial medicine. This study aimed to assess the power and quality of General Health Questionnaire (GHQ for prediction of the odds of chronicity of acute LBP. This study was conducted on industrial workers. All subjects with acute LBP who met the inclusion criteria were enrolled. Demographic characteristics, occupational, physical, and mental parameters and the general health status of subjects were evaluated;  they were followed up for developing chronic LBP for one year. Cigarette smoking, high body mass index, job stress, physical load and high GHQ scores were found to be the risk factors for the progression of acute LBP to chronic LBP (P<0.05. Standing position while working, age, work experience, exercise, level of education, weekly work hours and shift work were not the risk factors for chronic LBP (P>0.05.High GHQ score can be a risk factor for progression of acute LBP to chronic LBP. The GHQ in combination with the Job Content Questionnaire can be used as a quick and simple screening tool for detection of subjects at high risk of chronic LBP when evaluating acute LBP in an occupational setting.

Current therapies against toxoplasmosis are limited, and drugs have significant side effects and low efficacies. We evaluated the potential anti-Toxoplasma activity of propranolol at a dose of 2 or 3 mg/kg of body weight/day in vivo in the acute and chronic phases. Propranolol as a cell membrane-stabilizing agent is a suitable drug for inhibiting the entrance of Toxoplasma gondii tachyzoites into cells. The acute-phase assay was performed using propranolol, pyrimethamine, and propranolol plus pyrimethamine before (pretreatment) and after (posttreatment) intraperitoneal challenge with 1 × 103 tachyzoites of the virulent T. gondii strain RH in BALB/c mice. Also, in the chronic phase, treatment was performed 12 h before intraperitoneal challenge with 1 × 106 tachyzoites of the virulent strain RH of T. gondii in rats. One week (in the acute phase) and 2 months (in the chronic phase) after postinfection, tissues were isolated and DNA was extracted. Subsequently, parasite load was calculated using quantitative PCR (qPCR). In the acute phase, in both groups, significant anti-Toxoplasma activity was observed using propranolol (P toxoplasmosis. Also, propranolol combined with pyrimethamine reduced the parasite load as well as significantly increased survival of mice in the pretreatment group. In the chronic phase, anti-Toxoplasma activity and decreased parasite load in tissues were observed with propranolol. In conclusion, the presented results demonstrate that propranolol, as an orally available drug, is effective at low doses against acute and latent murine toxoplasmosis, and the efficiency of the drug is increased when it is used in combination therapy with pyrimethamine.

The category of 'acute and transient psychotic disorders' (ATPDs) appeared in the ICD-10 Classification of Mental and Behavioural Disorders (ICD-10), but its distinctive features remain uncertain. To examine the course and outcome of ATPDs, pointing out differences from other types of psychosis. A one-year follow-up investigation of patients enrolled at the former World Health Organization (WHO) Centre for Research and Training in Mental Health in Aarhus (Denmark) for the WHO collaborative study on acute psychoses. Of 91 patients aged 15-60 years presenting with acute psychosis, 47 (51.6%) were diagnosed with ATPD, and it occurred more commonly in females; yet, the other acute psychoses featured mainly mood disorders and affected equally both genders. After 1 year, the ATPD diagnosis did not change in 28 cases (59.6%); the remaining developed either affective psychoses (27.7%), or schizophrenia and schizoaffective disorder (12.8%). Nearly, all patients with unchanged diagnosis of ATPD enjoyed full recovery, while those with other types of acute psychosis had significantly higher rates of recurrence or incomplete remission. Duration of illness within 4 weeks and stressful events in the 3 months before symptom onset predicted 1-year favourable clinical outcome for acute psychoses.

Possible acute and late risks to the central nervous system (CNS) from galactic cosmic rays (GCR) and solar particle events (SPE) are concerns for human exploration of space. Acute CNS risks may include: altered cognitive function, reduced motor function, and behavioral changes, all of which may affect performance and human health. Late CNS risks may include neurological disorders such as Alzheimer's disease (AD), dementia and premature aging. Although detrimental CNS changes are observed in humans treated with high-dose radiation (e.g., gamma rays and 9 protons) for cancer and are supported by experimental evidence showing neurocognitive and behavioral effects in animal models, the significance of these results on the morbidity to astronauts has not been elucidated. There is a lack of human epidemiology data on which to base CNS risk estimates; therefore, risk projection based on scaling to human data, as done for cancer risk, is not possible for CNS risks. Research specific to the spaceflight environment using animal and cell models must be compiled to quantify the magnitude of CNS changes in order to estimate this risk and to establish validity of the current permissible exposure limits (PELs). In addition, the impact of radiation exposure in combination with individual sensitivity or other space flight factors, as well as assessment of the need for biological/pharmaceutical countermeasures, will be considered after further definition of CNS risk occurs.

The purpose of this study was to evaluate the safety and technical feasibility of a new thrombectomy device (Revive; Micrus Endovascular) in the endovascular treatment of acute ischemic stroke. Ten patients with acute large vessel occlusions were treated with the Revive device between October 2010 and December 2010. Mean National Institutes of Health Stroke Scale on admission was 19.0; mean duration of symptoms was 172 minutes. Recanalization was assessed using the Thrombolysis In Cerebral Infarction score. Clinical outcome (National Institutes of Health Stroke Scale) after thrombectomy was determined on Day 1, at discharge, and at Day 30. Vessel recanalization (Thrombolysis In Cerebral Infarction 2b or 3) was successful in all patients without device-related complications. Mean National Institutes of Health Stroke Scale 24 hours after the intervention, at discharge, and at Day 30 was 14.0, 11.5, and 5.1, respectively. At Day 30, 6 patients had a clinical improvement of >8 points or an National Institutes of Health Stroke Scale of 0 to 1, 1 patient showed minor improvement, and 3 patients had died. Symptomatic intracranial hemorrhage occurred in 2 patients, of which 1 was fatal. Thrombectomy with the Revive device in patients with stroke with acute large vessel occlusions demonstrated to be technically safe and highly effective. Clinical safety and efficacy have to be established in larger clinical trials.

To evaluate effectiveness of vestibular exercises in acute vertigo. 45 patients with acute vertigo were divided into 2 groups; 23 in study group (SG) and 22 in control group (CG). All patients were given tablet betahistine 24 mg twice daily as basic medical treatment and tablet Stemetil 5mg as a rescue. Those in SG also received vestibular exercise. Assessment was done using validated questionnaires, neuro-otology tests and individual diaries. Results : Intragroup comparison of intensity of symptoms showed a significant improvement from baseline, 3-month and 6-month visit with p<0.001. While intergroup comparison showed reduction of scores in both groups and which was greater in SG at 6 months visit. An improvement of neuro-otology tests was seen in all five tests whereby the Romber test, Unterberger-Fukuda test and spontaneous nystagmus test showed earlier improvement in SG at 3-month visit than CG. The SG also recovered faster and used lesser medication. 30.4% patients in SG were asymptomatic as early as first to third week after intervention. The number of rescue medications required in each group lessened towards the end of study. By week 7, 56.3% of SG and 43.8% of CG needed no rescue medication. (author)

Full Text Available Objective: To determine the effects of acute and chronic administration of methylprednisolone on oxidative stress, as quantified by measuring lipid peroxidation (LPO and total reactive antioxidant potential (TRAP, in rat lungs. Methods: Forty Wistar rats were divided into four groups: acute treatment, comprising rats receiving a single injection of methylprednisolone (50 mg/kg i.p.; acute control, comprising rats i.p. injected with saline; chronic treatment, comprising rats receiving methylprednisolone in drinking water (6 mg/kg per day for 30 days; and chronic control, comprising rats receiving normal drinking water. Results: The levels of TRAP were significantly higher in the acute treatment group rats than in the acute control rats, suggesting an improvement in the pulmonary defenses of the former. The levels of lung LPO were significantly higher in the chronic treatment group rats than in the chronic control rats, indicating oxidative damage in the lung tissue of the former. Conclusions: Our results suggest that the acute use of corticosteroids is beneficial to lung tissue, whereas their chronic use is not. The chronic use of methylprednisolone appears to increase lung LPO levels.

Several studies suggest users of 3,4-methylenedioxymethamphetamine (ecstasy) have low levels of serotonin. Low serotonin may make them susceptible to lowered mood. This work aims to study the acute effects on mood and impulsivity of lowering serotonin levels with acute tryptophan depletion in polydrug ecstasy users and to determine whether effects were different in men and women. In a double-blind cross-over study, participants who had used ecstasy at least 25 times (n = 13) and nonuser controls (n = 17) received a tryptophan-deficient amino acid mixture and a control amino acid mixture containing tryptophan, at least 1 week apart. Mood was measured using the profile of mood states, and impulsivity was measured with the Go/No-Go task. The main result shows that a lowering of mood after acute tryptophan depletion occurred only in female polydrug ecstasy users (n = 7), relative to controls (n = 9). Results from the Go/No-Go task suggested that impulsivity was not increased by acute tryptophan depletion in polydrug ecstasy users. The group sizes were small, when males and females were considered separately. Women polydrug ecstasy users appear to be more susceptible than men to the effects of lowered serotonin levels. If use of ecstasy alone or in conjunction with other drugs causes progressive damage of serotonin neurons, women polydrug ecstasy users may become susceptible to clinical depression.

Dating aggression is a prevalent and costly public health concern. Using a relational risk framework, this study examined acute and chronic relational risk factors (negative interactions, jealousy, support, and relationship satisfaction) and their effects on physical and psychological dating aggression. The study also examined the interaction between chronic and acute risk, allowing us to assess how changes in acute risk have differing effects depending on whether the individual is typically at higher chronic risk. A sample of 200 youth (100 female) completed seven waves of data, which spanned 9 years from middle adolescence to young adulthood (M age at Wave 1 = 15.83). Using hierarchical linear modeling, analyses revealed both acute (within-person) and chronic (between-person) levels in jealousy, negative interactions, and relationship satisfaction, were associated with physical and psychological dating aggression. Significant interactions between chronic and acute risk emerged in predicting physical aggression for negative interactions, jealousy, and relationship satisfaction such that those with higher levels of chronic risk are more vulnerable to increases in acute risk. These interactions between chronic and acute risk indicate that risk is not static, and dating aggression is particularly likely to occur at certain times for youth at high risk for dating aggression. Such periods of increased risk may provide opportunities for interventions to be particularly effective in preventing dating aggression or its consequences. Taken together, these findings provide support for the role of relational risk factors for dating aggression. They also underscore the importance of considering risk dynamically.

The biological effects of exposure to ionising radiation

International Nuclear Information System (INIS)

Higson, D.J.

Scenarios for exposure to ionising radiation range from natural background radiation (chronic) to the explosions of atomic bombs (acute), with some medical, industrial and research exposures lying between these extremes. Biological responses to radiation that predominate at high doses incurred at high dose rates are different from those that predominate at low doses and low dose rates. Single doses from bomb explosions ranged up to many thousand mGy. Acute doses greater than about 1000 mGy cause acute radiation syndrome (ARS). Below this threshold, radiation has a variety of potential latent health effects: Change to the incidence of cancer is the most usual subject of attention but change to longevity may be the best overall measure because decreased incidences of non-cancer mortality have been observed to coincide with increased incidence of cancer mortality. Acute doses greater than 500 mGy cause increased risks of cancer and decreased life expectancy. For doses less than 100 mGy, beneficial overall health effects ('radiation hormesis') have been observed. At the other end of the spectrum, chronic exposure to natural radiation has occurred throughout evolution and is necessary for the normal life and health of current species. Dose rates greater than the present global average of about 2 mGy per year have either no discernible health effect or beneficial health effects up to several hundred mGy per year. It is clearly not credible that a single health effects model -- such as the linear no-threshold (LNT) model of risk estimation -- could fit all latent health effects. A more realistic model is suggested.
