    The aim of this study was to identify possible health effects caused by different cleaning agents used in graffiti removal. In 38 graffiti removers working 8-h shifts in the Stockholm underground system, the exposure to organic solvents was assessed by active air sampling, biological monitoring, and by interviews and a questionnaire. Health effects were registered, by physical examinations, porta7ble spirometers and self-administered questionnaires. The prevalence of symptoms was compared with 49 controls working at the underground depots, and with 177 population controls. The 8-h time-weighted average exposures (TWA) were low, below 20% of the Swedish permissible exposure limit value (PEL) for all solvents. The short-term exposures occasionally exceeded the Swedish short-term exposure limit values (STEL), especially during work in poorly ventilated spaces, e.g. in elevators. The graffiti removers reported significantly higher prevalence of tiredness and upper airway symptoms compared with the depot controls, and significantly more tiredness, headaches and symptoms affecting airways, eyes and skin than the population controls. Among the graffiti removers, some of the symptoms increased during the working day. On a group basis, the lung function registrations showed normal values. However, seven workers displayed a clear reduction of peak expiratory flow (PEF) over the working shift. Though their average exposure to organic solvents was low, the graffiti removers reported significantly higher prevalence of unspecific symptoms such as fatigue and headache as well as irritative symptoms from the eyes and respiratory tract, compared with the controls. To prevent adverse health effects it is important to inform the workers about the health risks, and to restrict use of the most hazardous chemicals. Furthermore, it is important to develop good working practices and to encourage the use of personal protective equipment.

    There is a small body of evidence that supports the use of care pathways and assessment pro formas for the management of acute stroke patients, however, such tools applied specifically to the allied health disciplines are not in widespread use. This study sought to evaluate the effects of introducing an assessment pro forma on the allied health management of acute stroke patients. The allied health management of 40 consecutive stroke patients admitted after the introduction of the assessment pro forma was compared with that of a historical control group of the same size. The quality of allied health management was assessed by a variety of measures including the quality of documentation, the inclusion of specific recommended assessment components, the use of standardised assessment tools or outcome measures and the use of specific recommended interventions. These outcomes were used to calculate a total score for each of the allied health disciplines and the combined area of upper limb management, which were then used for analysis. At baseline, there was no statistically significant difference between the control and intervention groups. After the intervention, total allied health scores increased for all disciplines and for the upper limb management section. These increases were statistically significant for all disciplines (p forma specifically for the allied health disciplines may improve the management of acute stroke patients in terms of quality of documentation, and the use of specific assessment and treatment processes of care.

    Acute high-intensity physical exercise is known to improve cognitive performance of children, including those with attention-deficit/hyperactivity disorder (ADHD). In this work, we investigated the acute effect of an aerobic stretching and moderate-intensity, health and happiness improving movement (HHIM) exercise on the cortical activity of children with and without ADHD using electroencephalography (EEG). Children aged 12 to 14 yr with combined-type ADHD and age-matched healthy controls participated in the study, performing two individual movements (n=79, 35 controls) and a single exercise bout (n=45, 18 controls). electroencephalographic signals were recorded before and immediately after each movement, and before and after acute exercise under resting conditions, to obtain absolute and relative power estimates for the theta (3.5-8 Hz), alpha (8-12 Hz), sensory motor rhythm (12-16 Hz), and beta (16-25 Hz) bands. After acute HHIM exercise, all children showed significant changes in their relative EEG, mainly in the theta and alpha bands. Individual movements were found to influence relative theta, alpha and beta, and theta-to-beta ratios. He presents aerobic stretching HHIM exercise has demonstrated acute effect on the cortical activity of children.

  7. Acute Health Effects After the Elk River Chemical Spill, West Virginia, January 2014.

    On January 9, 2014, approximately 10 000 gallons of a mixture of 4-methylcyclohexanemethanol and propylene glycol phenyl ether spilled into West Virginia's Elk River, contaminating the potable water supply of about 300 000 West Virginia residents. This study sought to describe acute health effects after the chemical spill. We conducted a descriptive analysis using 3 complementary data sources: (1) medical records of patients who visited an emergency department during January 9-23, 2014, with illness potentially related to the spill; (2) West Virginia Poison Center caller records coded as "contaminated water" during January 9-23, 2014; and (3) answers to household surveys about health effects from a Community Assessment for Public Health Emergency Response (CASPER) questionnaire administered 3 months after the spill. In the 2 weeks after the spill, 2000 people called the poison center reporting exposure to contaminated water, and 369 people visited emergency departments in the affected area with reports of exposure and symptoms potentially related to the spill. According to CASPER weighted cluster analyses, an estimated 25 623 households (21.7%; 95% confidence interval [CI], 14.4%-28.9%) had ≥1 person with symptoms who felt that they were related to the spill in the 3 months after it. Reported health effects across all 3 data sources included mild skin, respiratory, and gastrointestinal symptoms that resolved with no or minimal treatment. Medical records, poison center data, and CASPER household surveys were inexact but useful data sources to describe overall community health effects after a large-scale chemical spill. Analyzing multiple data sources could inform epidemiologic investigations of similar events.

    Menthol reduces intestinal motility in animal studies, an effect that is probably mediated by transient receptor potential channels. Peppermint oil (PO), with menthol as a major constituent, is widely used as a spasmolytic agent in irritable bowel syndrome. In the current study, we investigated the effect of acute PO administration on intragastric pressure (IGP) profiles and gastric sensorimotor functions in health. Healthy volunteers underwent IGP measurement before and during continuous intragastric infusion of a nutrient drink (n = 13), and gastric barostat studies (n = 13). A single capsule of PO (182 mg) or placebo was administered during the studies in a randomized controlled crossover design. Throughout the studies, healthy volunteers scored 11 epigastric symptoms on a visual analogue scale (VAS); satiation was scored on a 6-point Likert scale during intragastric infusion. During fasting, IGP and motility index (MI) of the proximal stomach decreased significantly after PO administration compared with placebo (P IGP profiles, MI, satiation scores, and epigastric symptoms. The maximum infused volume, gastric compliance or sensitivity to balloon distention did not differ between both treatment arms. However, reduced appetite scores were seen during fasting after PO treatment, as compared with placebo (P = 0.01). Postprandial VAS scores were similar between PO and placebo. Peppermint oil reduces IGP, proximal phasic contractility, and appetite, with negligible effects on gastric sensitivity, tone, accommodation, and nutrient tolerance in health. © 2013 Blackwell Publishing Ltd.

    In 2008, the Kilauea Volcano on the island of Hawai'i increased eruption activity and emissions of sulfurous volcanic air pollution called vog. The purpose of this study was to promptly assess for a relative increase in cases of medically diagnosed acute illnesses in an exposed Hawaiian community. Using a within-clinic retrospective cohort design, comparisons were made for visits of acute illnesses during the 14 wk prior to the increased volcanic emissions (low exposure) to 14 wk of high vog exposure when ambient sulfur dioxide was threefold higher and averaged 75 parts per billion volume per day. Logistic regression analysis estimated effect measures between the low- and high-exposure cohorts for age, gender, race, and smoking status. There were statistically significant positive associations between high vog exposure and visits for medically diagnosed cough, headache, acute pharyngitis, and acute airway problems. More than a sixfold increase in odds was estimated for visits with acute airway problems, primarily experienced by young Pacific Islanders. These findings suggest that the elevated volcanic emissions in 2008 were associated with increased morbidity of acute illnesses in age and racial subgroups of the general Hawaiian population. Continued investigation is crucial to fully assess the health impact of this natural source of sulfurous air pollution. Culturally appropriate primary- and secondary-level health prevention initiatives are recommended for populations in Hawai'i and volcanically active areas worldwide.

    Acute exercise performed at a self-selected intensity improves affect and may improve long-term adherence. Similarly, in people with severe depression, acute aerobic exercise performed at self-selected intensity improves affect and arousal. However, the relationship between changes in affect and arousal and perceived exercise intensity in people with mental illness has not been evaluated. Affect and arousal were assessed immediately prior to, and immediately following, a group exercise program performed at a self-selected intensity in 40 inpatient mental health consumers who received a diagnosis of anxiety or bipolar or depressive disorders. Exercise intensity was assessed immediately after exercise. Postexercise affect was significantly improved for people with bipolar and depressive disorders but not for people with anxiety disorders. For the group as a whole, results showed a significant curvilinear relationship between ratings of perceived exertion and postexercise affect. These data will inform the development and delivery of future exercise interventions for inpatient mental health consumers.

    Full Text Available Abstract Background The project "Assessment and prevention of acute health effects of weather conditions in Europe" (PHEWE had the aim of assessing the association between weather conditions and acute health effects, during both warm and cold seasons in 16 European cities with widely differing climatic conditions and to provide information for public health policies. Methods The PHEWE project was a three-year pan-European collaboration between epidemiologists, meteorologists and experts in public health. Meteorological, air pollution and mortality data from 16 cities and hospital admission data from 12 cities were available from 1990 to 2000. The short-term effect on mortality/morbidity was evaluated through city-specific and pooled time series analysis. The interaction between weather and air pollutants was evaluated and health impact assessments were performed to quantify the effect on the different populations. A heat/health watch warning system to predict oppressive weather conditions and alert the population was developed in a subgroup of cities and information on existing prevention policies and of adaptive strategies was gathered. Results Main results were presented in a symposium at the conference of the International Society of Environmental Epidemiology in Paris on September 6th 2006 and will be published as scientific articles. The present article introduces the project and includes a description of the database and the framework of the applied methodology. Conclusion The PHEWE project offers the opportunity to investigate the relationship between temperature and mortality in 16 European cities, representing a wide range of climatic, socio-demographic and cultural characteristics; the use of a standardized methodology allows for direct comparison between cities.

    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.

    2015-03-01

    Multi-site time series studies have reported evidence of an association between short term exposure to particulate matter (PM) and adverse health effects, but the effect size varies across the United States. Variability in the effect may partially be due to differing community level exposure and health characteristics, but also due to the chemical composition of PM which is known to vary greatly by location and time. The objective of this article is to identify particularly harmful components of this chemical mixture. Because of the large number of highly-correlated components, we must incorporate some regularization into a statistical model. We assume that, at each spatial location, the regression coefficients come from a mixture model with the flavor of stochastic search variable selection, but utilize a copula to share information about variable inclusion and effect magnitude across locations. The model differs from current spatial variable selection techniques by accommodating both local and global variable selection. The model is used to study the association between fine PM (PM <2.5μm) components, measured at 115 counties nationally over the period 2000-2008, and cardiovascular emergency room admissions among Medicare patients.

    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.

    2011-10-01

    In air pollution epidemiology, there is a growing interest in estimating the health effects of coarse particulate matter (PM) with aerodynamic diameter between 2.5 and 10 μm. Coarse PM concentrations can exhibit considerable spatial heterogeneity because the particles travel shorter distances and do not remain suspended in the atmosphere for an extended period of time. In this paper, we develop a modeling approach for estimating the short-term effects of air pollution in time series analysis when the ambient concentrations vary spatially within the study region. Specifically, our approach quantifies the error in the exposure variable by characterizing, on any given day, the disagreement in ambient concentrations measured across monitoring stations. This is accomplished by viewing monitor-level measurements as error-prone repeated measurements of the unobserved population average exposure. Inference is carried out in a Bayesian framework to fully account for uncertainty in the estimation of model parameters. Finally, by using different exposure indicators, we investigate the sensitivity of the association between coarse PM and daily hospital admissions based on a recent national multisite time series analysis. Among Medicare enrollees from 59 US counties between the period 1999 and 2005, we find a consistent positive association between coarse PM and same-day admission for cardiovascular diseases.

    2007-11-01

    The Chernobyl accident resulted in almost one-third of the reported cases of acute radiation sickness (ARS) reported worldwide. Cases occurred among the plant employees and first responders but not among the evacuated populations or general population. The diagnosis of ARS was initially considered for 237 persons based on symptoms of nausea, vomiting, and diarrhea. Ultimately, the diagnosis of ARS was confirmed in 134 persons. There were 28 short term deaths of which 95% occurred at whole body doses in excess of 6.5 Gy. Underlying bone marrow failure was the main contributor to all deaths during the first 2 mo. Allogenic bone marrow transplantation was performed on 13 patients and an additional six received human fetal liver cells. All of these patients died except one individual who later was discovered to have recovered his own marrow and rejected the transplant. Two or three patients were felt to have died as a result of transplant complications. Skin doses exceeded bone marrow doses by a factor of 10-30, and at least 19 of the deaths were felt to be primarily due to infection from large area beta burns. Internal contamination was of relatively minor importance in treatment. By the end of 2001, an additional 14 ARS survivors died from various causes. Long term treatment has included therapy for beta burn fibrosis and skin atrophy as well as for cataracts.

  2. Effects of health intervention programs and arsenic exposure on child mortality from acute lower respiratory infections in rural Bangladesh.

    Respiratory infections continue to be a public health threat, particularly to young children in developing countries. Understanding the geographic patterns of diseases and the role of potential risk factors can help improve future mitigation efforts. Toward this goal, this paper applies a spatial scan statistic combined with a zero-inflated negative-binomial regression to re-examine the impacts of a community-based treatment program on the geographic patterns of acute lower respiratory infection (ALRI) mortality in an area of rural Bangladesh. Exposure to arsenic-contaminated drinking water is also a serious threat to the health of children in this area, and the variation in exposure to arsenic must be considered when evaluating the health interventions. ALRI mortality data were obtained for children under 2 years old from 1989 to 1996 in the Matlab Health and Demographic Surveillance System. This study period covers the years immediately following the implementation of an ALRI control program. A zero-inflated negative binomial (ZINB) regression model was first used to simultaneously estimate mortality rates and the likelihood of no deaths in groups of related households while controlling for socioeconomic status, potential arsenic exposure, and access to care. Next a spatial scan statistic was used to assess the location and magnitude of clusters of ALRI mortality. The ZINB model was used to adjust the scan statistic for multiple social and environmental risk factors. The results of the ZINB models and spatial scan statistic suggest that the ALRI control program was successful in reducing child mortality in the study area. Exposure to arsenic-contaminated drinking water was not associated with increased mortality. Higher socioeconomic status also significantly reduced mortality rates, even among households who were in the treatment program area. Community-based ALRI interventions can be effective at reducing child mortality, though socioeconomic factors may

However, both music therapy conditions tended to have slightly higher mean pathway, agency, and total state hope scores than the control condition even within the temporal parameters of a single music therapy session. There was no between-group difference in the songwriting and lyric analysis interventions. Conclusions: Although not significant, results support that educational music therapy may impact state hope for recovery within the temporal parameters of a single session. The specific type of educational music therapy intervention did not affect results. Implications for practice, limitations, and suggestions for future research are provided.

    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.

    Acute kidney injury (AKI) is increasingly prevalent in developing and developed countries and is associated with severe morbidity and mortality.Most etiologies of AKI can be prevented by interventions at the individual,community,regional and in-hospital levels.Effective measures must include community-wide efforts to increase an awareness of the devastating effects of AKI and provide guidance on preventive strategies,as well as early recognition and management.Efforts should be focused on minimizing causes of AKI,increasing awareness of the importance of serial measurements of serum creatinine in high risk patients,and documenting urine volume in acutely ill people to achieve early diagnosis; there is as yet no definitive role for alternative biomarkers.Protocols need to be developed to systematically manage prerenal conditions and specific infections.More accurate data about the true incidence and clinical impact of AKI will help to raise the importance of the disease in the community,increase awareness of AKI by governments,the public,general and family physicians and other health care professionals to help prevent the disease.Prevention is the key to avoid the heavy burden of mortality and morbidity associated with AKI.

    To examine hypotheses regarding health effects of particulate matter, we conducted time series studies in Austrian urban and rural areas. Of the pollutants measured, ambient PM 2.5 was most consistently associated with parameters of respiratory health. Time series studies applying semiparametric generalized additive models showed significant increases of respiratory hospital admissions (ICD 490-496) at age 65 and older. The early increase of 5.5% in Vienna at a lag of 2 days in males and of 5.6% per 10 μg/m 3 at a lag of 3 days in females was not observed in a nearby rural area. Another increase of respiratory admissions (mainly COPD) was observed after a lag of 10-11 days. A time series on a panel of 56 healthy preschool children showed a significant impact of the carbonaceous fraction of PM 2.5 on tidal breathing pattern assessed by inductive plethysmography. In repeated oscillometric measurements of respiratory resistance in 164 healthy elementary school children not only immediate responses to fine particulates were found but also latent ones, possibly indicating inflammatory changes in airways. It may be speculated that the improvements of urban air quality prevented measurable effects on respiratory mortality. More sensitive indicators, however, still show acute impairments of respiratory function and health in elderly and children which are associated with fine particulates and subfractions related to motor traffic.

    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

  12. Health Impacts from Acute Radiation Exposure

    Strom, Daniel J.

    2003-09-30

    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.

    Acute and chronic life stressors have a detrimental effect on the health of people living with HIV. Psychosocial resources such as mastery, coping, and social support may play a critical role in moderating the negative effects of stressors on health-related quality of life. A total of 758 participants provided baseline enrolment data on demographics (age, gender, ethnicity, sexual orientation, education, employment, income), clinical variables (CD4 counts, viral load, AIDS-defining condition, time since HIV diagnosis), psychosocial resources (mastery, coping, social support), life stressors (National Population Health Survey [NPHS] Stress Questionnaire), and health-related quality of life (SF-36). We performed hierarchical multivariate regression analyses to evaluate the potential moderating effects of psychosocial resources on the relationship between stressors and health-related quality of life. The top three stressors reported by participants were trying to take on too many things at once (51%), not having enough money to buy the things they needed (51%), and having something happen during childhood that scared them so much that they thought about it years later (42%). Life stressors were significantly and inversely associated with both physical and mental health-related quality of life. Mastery and maladaptive coping had significant moderating effects on mental health but not on physical health. These results suggest that developing interventions that improve mastery and reduce maladaptive coping may minimize the negative impact of life stressors on the mental health of people with HIV. They also highlight that it is important for clinicians to be mindful of the impact of life stressors on the health of patients living with HIV.

    The purpose of this study was to evaluate the effect of low-level laser therapy (LLLT) as an adjunct to standard therapy in acute pericoronitis. Eighty acute pericoronitis patients were randomly assigned to one of four LLLT groups: (neodymium:yttrium-aluminum garnet [Nd:YAG] 1064-nm: n=20, 8 J/cm2, 0.25 W, 10 Hz, 10 sec; 808-nm diode: n=20, 8 J/cm2, 0.25 W, continuous mode, 10 sec; 660-nm diode: n=20, 8 J/cm2, 0.04 W, continuous mode, 60 sec; or a placebo laser control group: n=20). After standard treatment, LLLT or a placebo laser were applied to the treatment area at a distance of 1 cm from the buccal site. Interincisal opening, pain perception, and oral health-related quality of life (OHRQoL) were evaluated at baseline, 24 h, and 7 days after laser application. The data were analyzed by the one-way ANOVA test. We found that the trismus and the OHRQoL in the Nd:YAG and the 808-nm diode groups were significantly improved when compared with the 660-nm diode and control groups at 24 h (ppericoronitis. Taking into account the limitations of this study, we conclude that the 1064-nm Nd:YAG laser has biostimulatory effects and improves OHRQoL, making it suitable for LLLT.

  1. Mental health nurses' views of recovery within an acute setting.

    2013-06-01

    How the principles of a recovery-oriented mental health service are incorporated in the day-to-day nursing practice of mental health nurses in inpatient settings is unclear. In this study, we interviewed 21 mental health nurses working in acute inpatient mental health units about a range of recovery-focused topics. Three overlapping themes were identified: (i) the perception of recovery; (ii) congruent humanistic approaches; and (iii) practical realities. Only four interviewees had some formal training about recovery. Most respondents recognize that positive attitudes, person-centred care, hope, education about mental illness, medication and side-effects, and the acknowledgement of individual recovery pathways are necessary to prevent readmission, and are central to a better life for people who live with a mental illness. This research supports the view that ideas and practices associated with the recovery movement have been adopted to some degree by nurses working at the acute end of the services continuum. However, most saw the recovery orientation as rhetoric rather than as an appropriately resourced, coordinated, and integrated program. These nurses, however, speak of much more detailed aspects of working with patients and being required to prepare them for the exigencies of living in the community post-discharge.

  2. Health Care Seeking Behavior of Persons with Acute Chagas Disease in Rural Argentina: A Qualitative View

    Dinardi, Graciela; Canevari, Cecilia; Torabi, Nahal

    2016-01-01

    Chagas disease (CD) is a tropical parasitic disease largely underdiagnosed and mostly asymptomatic affecting marginalized rural populations. Argentina regularly reports acute cases of CD, mostly young individuals under 14 years old. There is a void of knowledge of health care seeking behavior in subjects experiencing a CD acute condition. Early treatment of the acute case is crucial to limit subsequent development of disease. The article explores how the health outcome of persons with acute CD may be conditioned by their health care seeking behavior. The study, with a qualitative approach, was carried out in rural areas of Santiago del Estero Province, a high risk endemic region for vector transmission of CD. Narratives of 25 in-depth interviews carried out in 2005 and 2006 are analyzed identifying patterns of health care seeking behavior followed by acute cases. Through the retrospective recall of paths for diagnoses, weaknesses of disease information, knowledge at the household level, and underperformance at the provincial health care system level are detected. The misdiagnoses were a major factor in delaying a health care response. The study results expose lost opportunities for the health care system to effectively record CD acute cases. PMID:27829843

    Full Text Available Purpose: We investigated factors driving health care costs of patients with a diagnosis of acute myeloid and acute lymphoblastic leukemia. Methods: Standard costs identified in insurance claims data obtained from the Wisconsin Health Information Organization were used in a sample of 837 acute leukemia patients from April 2009 to June 2011. The Andersen behavioral model of health care utilization guided selection of patient and community factors expected to influence health care costs. A generalized linear model fitting gamma-distributed data with log-link technique was used to analyze cost. Results: Type of treatment received and disease severity represented significant cost drivers, and patients receiving at least some of their treatment from academic medical centers experienced higher costs. Inpatient care and pharmacy costs of patients who received treatment from providers located in areas of higher poverty experienced lower costs, raising questions of potential treatment and medical practice disparities between provider locations. Directions of study findings were not consistent between different types of services received and underscore the complexity of investigating health care cost. Conclusions: While prevalence of acute leukemia in the United States is low compared to other diseases, its extreme high cost of treatment is not well understood and potentially influences treatment decisions. Acute leukemia health care costs may not follow expected patterns; further exploration of the relationship between cost and the treatment decision, and potential treatment disparities between providers in different socioeconomic locations, is needed.

    2010-08-01

    Full Text Available Abstract Background The economical impact of absenteeism and reduced productivity due to acute infectious respiratory and gastrointestinal disease is normally not in the focus of surveillance systems and may therefore be underestimated. However, large community studies in Europe and USA have shown that communicable diseases have a great impact on morbidity and lead to millions of lost days at work, school and university each year. Hand disinfection is acknowledged as key element for infection control, but its effect in open, work place settings is unclear. Methods Our study involved a prospective, controlled, intervention-control group design to assess the epidemiological and economical impact of alcohol-based hand disinfectants use at work place. Volunteers in public administrations in the municipality of the city of Greifswald were randomized in two groups. Participants in the intervention group were provided with alcoholic hand disinfection, the control group was unchanged. Respiratory and gastrointestinal symptoms and days of work were recorded based on a monthly questionnaire over one year. On the whole, 1230 person months were evaluated. Results Hand disinfection reduced the number of episodes of illness for the majority of the registered symptoms. This effect became statistically significant for common cold (OR = 0.35 [0.17 - 0.71], p = 0.003, fever (OR = 0.38 [0.14-0.99], p = 0.035 and coughing (OR = 0.45 [0.22 - 0.91], p = 0.02. Participants in the intervention group reported less days ill for most symptoms assessed, e.g. colds (2.07 vs. 2.78%, p = 0.008, fever (0.25 vs. 0.31%, p = 0.037 and cough (1.85 vs. 2.00%, p = 0.024. For diarrhoea, the odds ratio for being absent became statistically significant too (0.11 (CI 0.01 - 0.93. Conclusion Hand disinfection can easily be introduced and maintained outside clinical settings as part of the daily hand hygiene. Therefore it appears as an interesting, cost-efficient method within the scope

    Large and growing segments of the United States population consume seafood or engage in marine recreation. These activities provide significant benefits but also bring risk of exposure to marine-borne illness. To manage these risks, it is important to understand the incidence and cost of marine-borne disease. We review the literature and surveillance/monitoring data to determine the annual incidence of disease and health consequences due to marine-borne pathogens from seafood consumption and beach recreation in the USA. Using this data, we employ a cost-of-illness model to estimate economic impacts. Our results suggest that health consequences due to marine-borne pathogens in the USA have annual costs on the order of US$900 million. This includes US$350 million due to pathogens and marine toxins specifically identified as causing food-borne disease, an estimated US$300 million due to seafood-borne disease with unknown etiology, US$30 million from direct exposure to the Vibrio species, and US$300 million due to gastrointestinal illness from beach recreation. Although there is considerable uncertainty about the degree of underreporting of certain pathogen-specific acute marine-related illnesses, the conservative assumptions we have used in constructing our estimate suggest that it should be considered a lower bound on true costs.

    Background: the aim of the study was to assess the safety, efficacy and cost-effectiveness of negative Pressure wound therapy (nPT for people with chronic and acute wounds.

    Methods: the scope and the final draft of the report have been submitted to the stakeholders (producers, payers and patients. safety issues were addressed through a systematic review of the meta-literature. efficacy was addressed through a systematic review and meta-analysis of randomized controlled trials (rcTs comparing nPT and other standard therapies in patients with chronic or acute lesions. cost-consequence was analyzed through a systematic review of the existing studies.

    Results: we retrieved 19 studies, 13 of which were included in the meta-analysis. Many studies had biases that may have resulted in a better performance for nPT. nPT showed: a slightly shorter healing time (-10.4 days, p=0.001, with no heterogeneity, apart from one small study with very positive results, and 40% more patients healed (p=0.002, no heterogeneity.We identified 15 original research papers on nPT costs and cost per outcome. The costs-per-patient- treated varied from +29% to -60%, with several studies reporting savings for nPT.

    Conclusions: despite serious methodological flaws, the body of evidence available was sufficient to prove some clinical benefit of nPT in severe chronic and acute wound treatment. There is a need for independent and contextualized cost analyses....

    2015-01-01

    An acute mental health triage ward at Oxleas NHS Foundation Trust was attracting high levels of formal service user and family complaints. The Trust used experience based co-design to examine the issues and redesign procedures. This resulted in an immediate eradication of formal complaints for a period of 23 months. This paper describes two outcomes: firstly, the successful adaptations made to the experience based co-design methodology from its origins in physical care, in order to ensure it was safe and effective in an acute mental health setting; and, secondly, the changes made to the ward as a result of this quality improvement intervention.

    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.

    Full Text Available Abstract 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.

    Some questions associated with statistical inference of doubly stochastic Poisson processes are discussed. This general model appears to be of value in studying a number of problems in environmental health in which the factors which affect the rate at which certain diseases occur cannot be deterministically characterized. The model's applicability to a study of air pollution and incidence of acute respiratory diseases in the New York City area is examined.

    A focus group using nursing informatics experts as informants was conducted to guide development of a survey to explore the impact of health information technology on the role of nurses and interdisciplinary communication in acute care settings. Through analysis of focus group transcripts, five key themes emerged: information, communication, care coordination, interdisciplinary relationships, workflow, and practice effectiveness and efficiency. This served as the basis for development of a survey that will investigate perceptions of acute care providers across the United States regarding the impact of health information technology on the role of nurses and interdisciplinar communication in acute care settings. The purpose of this paper is to describe the process of survey development including analysis of transcripts, emergence of key themes, and the processes by which the themes will be employed to inform survey development.

    2012-06-01

    Full Text Available Abstract Background Acute hospital discharge delays are a pressing concern for many health care administrators. In Canada, a delayed discharge is defined by the alternate level of care (ALC construct and has been the target of many provincial health care strategies. Little is known on the patient characteristics that influence acute ALC length of stay. This study examines which characteristics drive acute ALC length of stay for those awaiting nursing home admission. Methods Population-level administrative and assessment data were used to examine 17,111 acute hospital admissions designated as alternate level of care (ALC from a large Canadian health region. Case level hospital records were linked to home care administrative and assessment records to identify and characterize those ALC patients that account for the greatest proportion of acute hospital ALC days. Results ALC patients waiting for nursing home admission accounted for 41.5% of acute hospital ALC bed days while only accounting for 8.8% of acute hospital ALC patients. Characteristics that were significantly associated with greater ALC lengths of stay were morbid obesity (27 day mean deviation, 99% CI = ±14.6, psychiatric diagnosis (13 day mean deviation, 99% CI = ±6.2, abusive behaviours (12 day mean deviation, 99% CI = ±10.7, and stroke (7 day mean deviation, 99% CI = ±5.0. Overall, persons with morbid obesity, a psychiatric diagnosis, abusive behaviours, or stroke accounted for 4.3% of all ALC patients and 23% of all acute hospital ALC days between April 1st 2009 and April 1st, 2011. ALC patients with the identified characteristics had unique clinical profiles. Conclusions A small number of patients with non-medical days waiting for nursing home admission contribute to a substantial proportion of total non-medical days in acute hospitals. Increases in nursing home capacity or changes to existing funding arrangements should target the sub

    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.

    The present study assessed the acute effects of smoked marijuana on social conversation. Speech quantity was recorded continuously in seven moderate marijuana users during separate 1 h experimental sessions following the paced smoking of 0, 1.01, 1.84, and 2.84% THC marijuana cigarettes. Subjects engaged in conversation with undrugged partners who smoked placebo marijuana cigarettes. The active marijuana produced significant decreases in speech quantity, increases in heart rate, and increases in self-reports of "high" and sedation. Partners showed no effects in speech quantity or self-reports of drug effects that were systematically related to the doses administered to the subject pair members. The effects on speech quantity observed in the present study after acute dosing are similar to the effects on social conversation reported previously during chronic marijuana dosing. Marijuana appears to be an exception to the general rule that drugs of abuse increase verbal interaction.

  20. Protective Effect of Melatonin on Acute Pancreatitis

    2012-01-01

    Full Text Available Melatonin, a product of the pineal gland, is released from the gut mucosa in response to food ingestion. Specific receptors for melatonin have been detected in many gastrointestinal tissues including the pancreas. Melatonin as well as its precursor, L-tryptophan, attenuates the severity of acute pancreatitis and protects the pancreatic tissue from the damage caused by acute inflammation. The beneficial effect of melatonin on acute pancreatitis, which has been reported in many experimental studies and supported by clinical observations, is related to: (1 enhancement of antioxidant defense of the pancreatic tissue, through direct scavenging of toxic radical oxygen (ROS and nitrogen (RNS species, (2 preservation of the activity of antioxidant enzymes; such as superoxide dismutase (SOD, catalase (CAT, or glutathione peroxidase (GPx, (3 the decline of pro-inflammatory cytokine tumor necrosis α (TNFα production, accompanied by stimulation of an anti-inflammatory IL-10, (4 improvement of pancreatic blood flow and decrease of neutrophil infiltration, (5 reduction of apoptosis and necrosis in the inflamed pancreatic tissue, (6 increased production of chaperon protein (HSP60, and (7 promotion of regenerative process in the pancreas. Conclusion. Endogenous melatonin produced from L-tryptophan could be one of the native mechanisms protecting the pancreas from acute damage and accelerating regeneration of this gland. The beneficial effects of melatonin shown in experimental studies suggest that melatonin ought to be employed in the clinical trials as a supportive therapy in acute pancreatitis and could be used in people at high risk for acute pancreatitis to prevent the development of pancreatic inflammation.

    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 animals exposed to space flight stressors combined with the types of radiation expected during an SPE. 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). All animal studies described have been approved by the University of PA IACUC. Some conclusions from recent CARR investigations are as follows: (i) the relative biological effectiveness (RBE) values for SPE-like protons compared with standard reference radiations (gammas or electrons) for white blood cells (WBCs) vary greatly between mice, ferrets and pigs, with the RBE values being greater in ferrets than those in mice, and considerably greater in pigs compared with those in ferrets or mice [1, 2]. This trend for the data suggests that the RBE values for WBCs in humans could be considerably greater than those observed in small mammals, and SPE proton radiation may be far more hazardous to humans than previously estimated from small animal studies. (ii) Very low doses of SPE proton radiation (25 cGy) increase blood clotting times in ferrets, and the low SPE-like dose rate has more severe effects than high dose rate radiation [3]. (iii) Results from pig and ferret studies suggest that disseminated intravascular coagulation is a major cause of death at doses near the LD50 level for SPE-like proton and gamma radiation. (iv) Exposure to SPE-like proton or gamma radiation, in combination with

    Full Text Available Psychological reactions, risk health behavior and cardiac parameters can influence rehospitalization after acute myocardial infarction.The aim of the paper was to determine the presence of psychological reactions and risk health behavior in patients with acute myocardial infarction on admission as well as the differences after six months.The research included thirty-trhee patients of both sexes, who were consecutively hospitalized due to acute myocardial infarction. A prospective clinical investigation involved the following: semi-structured interview, Mini International Neuropsychiatric Interview (M.I.N.I for pcychiatric disorders, Beck Anxiety Inventory (BAI for measuring the severity of anxiety, Beck Depression Inventory (BDI for measuring the severity of depression, KON-6 sigma test for aggression, Holms-Rahe Scale (H-R for exposure to stressful events, and Health Behavior Questionnaire: alcohol consumption, cigarette smoking, lack of physical activity. Measurement of the same parameters was done on admission and after six months. The differences were assessed using the t-test and chi-square test for p<0.05.On admission, anxiety (BAI=8.15±4.37 and depression (BDI=8.67±3.94 were mild without significant difference after six months in the group of examinees. Aggression was elevated and significantly lowered after six monts (KON-6 sigma =53,26±9, 58:41,42±7.67, t=2,13 for p<0.05.

    Full Text Available Acute rheumatic fever remains a public health concern in developing countries as well as in poorer communities and among indigenous populations in some developed nations. It poses serious economic problem at individual, communal and national levels through direct and indirect health care costs. The objective of this article is to review acute rheumatic fever in the global context with some emphasis on the continuing burden of this disease in the developing settings. The Cochrane Database of Systematic Reviews, PubMed, EMBASE and AJOL were searched with focus on epidemiology, pathogenesis, diagnosis and treatment, and control of acute rheumatic fever. The review shows that acute rheumatic fever still occurs under conditions of impoverished overcrowding and poor sanitation and where access to healthcare services is limited. Since acute rheumatic fever is a preventable disease, improved housing and sanitation, access to effective healthcare services, early diagnosis, registration of cases and follow up remain the bedrock of the control of this disease [Archives Medical Review Journal 2013; 22(2.000: 153-169

    Full Text Available Ritual use of ayahuasca, an amazonian Amerindian medicine turned sacrament in syncretic religions in Brazil, is rapidly growing around the world. Because of this internationalization, a comprehensive understanding of the pharmacological mechanisms of action of the brew and the neural correlates of the modified states of consciousness it induces is important. Employing a combination of electroencephalogram (EEG recordings and quantification of ayahuasca's compounds and their metabolites in the systemic circulation we found ayahuasca to induce a biphasic effect in the brain. This effect was composed of reduced power in the alpha band (8-13 Hz after 50 minutes from ingestion of the brew and increased slow- and fast-gamma power (30-50 and 50-100 Hz, respectively between 75 and 125 minutes. Alpha power reductions were mostly located at left parieto-occipital cortex, slow-gamma power increase was observed at left centro-parieto-occipital, left fronto-temporal and right frontal cortices while fast-gamma increases were significant at left centro-parieto-occipital, left fronto-temporal, right frontal and right parieto-occipital cortices. These effects were significantly associated with circulating levels of ayahuasca's chemical compounds, mostly N,N-dimethyltryptamine (DMT, harmine, harmaline and tetrahydroharmine and some of their metabolites. An interpretation based on a cognitive and emotional framework relevant to the ritual use of ayahuasca, as well as it's potential therapeutic effects is offered.

    2012-11-01

    A double-blind, placebo-controlled, crossover design was employed to determine whether acute lorazepam (2 mg orally) cognitive side effects would emerge in a differential age-dependent fashion in 15 young (mean age=22 years) and 12 older (mean age=64 years) subjects. Acute use of lorazepam is frequently the initial treatment choice for convulsive status epilepticus or repetitive seizure clusters. Cognitive assessment was performed during drug and placebo conditions using a computerized battery of cognitive tests. With the exception of performance on the reasoning composite score, significant drug effects were present on all primary cognitive domain measures. However, the only significant drug-by-age interaction effect was seen for dual-task performance. The relationship between test performance and plasma lorazepam concentrations was generally modest and non-significant, suggesting that individual differences in pharmacokinetics are not a major factor contributing to the emergence of cognitive side effects. Despite robust lorazepam effects on multiple measures of neurocognitive function, differential age effects are largely restricted to dual-task performance. These results indicate that with the exception of dual-task performance, older individuals in the age range of this study do not appear to be at increased risk for the emergence of cognitive side effects following a single 2-mg dose of lorazepam.

Nurse health-related quality of life is an important health outcome, and should be promoted for quality nursing care. This cross-sectional study was conducted on nurses who work in general acute care wards in three university hospitals in metropolitan Japan. Multilevel analysis was conducted to investigate possible factors related to nurse health-related quality of life. Nurses who worked at a ward had a significantly lower physical health score (β = -0.13, P characteristics. Further large-scale studies are needed in order to investigate the effect of hospital characteristics on nurse health-related quality of life. Increasing the number of nurses' aides and delegating assistance with ADL to them could support nurse health-related quality of life in the acute care setting. © 2014 John Wiley & Sons Ltd.

    Full Text Available Ionizing radiation has become an inevitable health concern emanating from natural sources like space travel and from artificial sources like medical therapies. In general, exposure to ionizing radiation such as γ-rays is one of the methods currently used to stress specific model systems. In this study, we elucidated the long-term effect of acute and fractionated irradiation on DCX-positive cells in hippocampal neurogenesis. Groups of two-month-old C57BL/6 female mice were exposed to whole-body irradiation at acute dose (5 Gy or fractional doses (1 Gy × 5 times and 0.5 Gy × 10 times. Six months after exposure to γ-irradiation, the hippocampus was analyzed. Doublecortin (DCX immunohistochemistry was used to measure changes of neurogenesis in the subgranular zone (SGZ of the hippocampal dentate gyrus (DG. The number of DCX-positive cells was significantly decreased in all acute and fractionally irradiation groups. The long-term changes in DCX-positive cells triggered by radiation exposure showed a very different pattern to the short-term changes which tended to return to the control level in previous studies. Furthermore, the number of DCX-positive cells was relatively lower in the acute irradiation group than the fractional irradiation groups (approximately 3.6-fold, suggesting the biological change on hippocampal neurogenesis was more susceptible to being damaged by acute than fractional irradiation. These results suggest that the exposure to γ-irradiation as a long-term effect can trigger biological responses resulting in the inhibition of hippocampal neurogenesis.

    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

    2013-12-01

    Use of electricity causes extremely low frequency magnetic fields (ELF-MF) and wireless communication devices emit radiofrequency electromagnetic fields (RF-EMF). Average ELF-MF exposure is mainly determined by high voltage power lines and transformers at home or at the workplace, whereas RF-EMF exposure is mainly caused by devices operating close to the body (mainly mobile and cordless phones). Health effects of EMF are controversially discussed. The IARC classified ELF-MF and RF-EMF as possible carcinogenic. Most consistent epidemiological evidence was found for an association between ELF-MF and childhood leukaemia. If causal, 1 - 4 percent of all childhood leukaemia cases could be attributed to ELF-MF. Epidemiological research provided some indications for an association between ELF-MF and Alzheimer's diseases as well as amyotrophic lateral sclerosis, although not entirely consistent. Regarding mobile phones and brain tumours, some studies observed an increased risk after heavy or long term use on the one hand. On the other hand, brain tumour incidence was not found to have increased in the last decade in Sweden, England or the US. Acute effects of RF-EMF on non-specific symptoms of ill health seem unlikely according to randomized and double blind provocation studies. However, epidemiological research on long term effects is still limited. Although from the current state of the scientific knowledge a large individual health risk from RF-EMF exposure is unlikely, even a small risk would have substantial public health relevance because of the widespread use of wireless communication technologies.

    Previous studies have established a relationship between marijuana use and risky behavior in natural settings. A limited number of laboratory investigations of marijuana effects on human risk taking have been conducted. The present study was designed to examine the acute effects of smoked marijuana on human risk taking, and to identify behavioral mechanisms that may be involved in drug-induced changes in the probability of risky behavior. Using a laboratory measure of risk taking designed to address acute drug effects, 10 adults were administered placebo cigarettes and three doses of active marijuana cigarettes (half placebo and half 1.77%; 1.77%; and 3.58% Delta9-THC) in a within-subject repeated-measures experimental design. The risk-taking task presented subjects with a choice between two response options operationally defined as risky and nonrisky. Data analyses examined cardiovascular and subjective effects, response rates, distribution of choices between the risky and nonrisky option, and first-order transition probabilities of trial-by-trial data. The 3.58% THC dose increased selection of the risky response option, and uniquely shifted response probabilities following both winning and losing outcomes following selection of the risky option. Acute marijuana administration thereby produced measurable changes in risky decision making under laboratory conditions. Consistent with previous risk-taking studies, shifts in trial-by-trial response probabilities at the highest dose suggested a change in sensitivity to both reinforced and losing risky outcomes. Altered sensitivity to consequences may be a mechanism in drug-induced changes in risk taking. Possible neurobiological sites of action related to THC are discussed.

    In India, common morbidities among children under 3 years of age are fever, acute respiratory infections, diarrhea. Effective early management at the home level and health care-seeking behavior in case of appearance of danger signs are key strategies to prevent the occurrence of severe and life-threatening complications. To find out the prevalence of acute child morbidities, their determinants and health-seeking behavior of the mothers of these children. The cross-sectional study was carried out in Wardha district of central India. We interviewed 990 mothers of children below 3 years of age using 30-cluster sampling method. Nutritional status was defined by National Center for Health Statistics (NCHS) reference. Composite index of anthropometric failure (CIAF) was constructed. Hemoglobin concentration in each child was estimated using the 'filter paper cyanm ethemoglobin method.' Using World Health Organization guidelines, anemia was defined as hemoglobin concentration less than 110 g/L. Post-survey focus group discussions (FGDs) were undertaken to bridge gaps in information obtained from the survey. The data was analyzed by using SPSS 12.0.1 software package. Chi-square was used to test the association, while odds ratios were calculated to measure the strength of association. Multiple logistic regression analysis was applied to derive the final model. Anemia was detected in 80.3% of children, and 59.6% of children were undernourished as indicated by CIAF. The overall prevalence of acute morbidity was 59.9%. Children with mild anemia, moderate anemia and severe anemia had 1.52, 1.61 and 9.21 times higher risk of being morbid, respectively. Similarly, children with single, 2 and 3 anthropometric failures had 1.16, 1.29 and 2.27 times higher risk of being morbid, respectively. Out of 594 (60%) children with at least one of the acute morbidities, 520 (87.5%) sought health care, where majority (66.1%) received treatment from private clinics. The final model suggested

    Full Text Available Background: This study sought to characterise acute poisoning cases seen in three health districts of Botswana.Method: A retrospective review of patients’ records was conducted and included patients treated from January 2004 to December 2005. Data on the demographic status of the patients, information about the poisonous agent(s involved, and the circumstances and outcomes of the poisoning incidents were recorded on a pre-tested data collection form.Results: A total of 590 cases of acute poisoning were included in the analysis. The most affected age category was that of children aged less than six years, who constituted 33.4% of the cases. Most incidents were recorded in the urban district of Gaborone. Seventy-eight percent (78% of the incidents were accidental, with the remainder being intentional. The poisonous agents involved were pharmaceuticals (26.6%, natural toxins (25.6%, household products (14.6%, foods (14.4%, alcohol (6.9%, traditional medicines (4.7%, unspecified agents (3.2%, and agrochemicals (2.7%. The most common route of poison exposure was by oral (82.2%, followed by dermal contact (16.5%, while the inhalation of gases occurred in 1.2% of cases. An incidence rate of 4.7/1000, a case fatality rate of 3.8/100, and 1.5% of deaths were recorded over the two-year period.Conclusion: In conclusion, it can be stated that acute poisoning involved mainly young children and resulted in an incidence rate of 4.7/1000, a case fatality rate of 3.8/100, and 1.5% of deaths over the two-year period. There were differences based on age category, gender and residence of the victims, the types of toxic agents involved, as well as the circumstances and the outcomes of the poisoning incidents. Given the fact that pharmaceuticals, natural toxins, household products and foods were the agents most commonly involved, targeted interventions should take these differences into account in addressing the problem of acute poisoning.

    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.

    Specialized stroke units offer optimal treatment of patients with an acute stroke. Unfortunately, their installation is limited by an acute lack of experienced neurologists and the small number of stroke patients in sparsely populated rural areas. This problem is increasingly being solved by the use of telemedicine, so that neurological expertise is made available to basic and regular care. It has been demonstrated by national and international pilot studies that solidly based and rapid decisions can be made by telemedicine regrading the use of thrombolysis, as the most important acute treatment, but also of other interventions. So far studies have only evaluated improvement in the quality of care achieved by networking, but not of any lasting effect on any economic benefit. Complementary to a medical evaluation, the qualitative economic assessment presented here of German and American concepts of telemetric care indicate no difference in efficacy between various ways of networking. Most noteworthy, when comparing two large American and German studies, is the difference in their priorities. While the American networks achieved targeted improvements in efficacy of care that go beyond the immediate wishes of the doctors involved, this was of only secondary importance in the German studies. Also, in contrast to several American networks, the German telemetry networks have not tended to be organized for future growth. In terms of economic benefits, decentralized organized networks offer a greater potential of efficacy than purely local ones. Furthermore, the integration of inducements into the design of business models is a fundamental factor for achieving successful and lasting existence, especially within a highly competitive market.

    With the advent of an increased emphasis on the potential to utilize biomarkers in saliva for systemic diseases, the issue of existing oral disease is an important consideration that could adversely affect the interpretation of diagnostic results obtained from saliva. We addressed the question does a patient's oral inflammation status confound biomarker levels used in diagnosis of acute myocardial infarction (AMI). The results demonstrated that multiple serum biomarkers and a few salivary biomarkers reflected the cardiac event. Importantly, oral health of the individual had minimal impact on the validity of the serum or salivary biomarker effectiveness.

    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.

    Consuming a diet rich in plant foods will provide a milieu of phytochemicals, non-nutritive substances in plants that possess health-protective benefits. Vegetables, fruits, whole grains, herbs, nuts and seeds contain an abundance of phenolic compounds, terpenoids, sulfur compounds, pigments, and other natural antioxidants that have been associated with protection from and/or treatment of conditions such as cardiovascular disease and cancer. The foods and herbs with the highest anticancer activity include garlic, soybeans, cabbage, ginger, licorice root, and the umbelliferous vegetables. Citrus, in addition to providing an ample supply of vitamin C, folic acid, potassium, and soluble fibre, contains a host of active phytochemicals. Clinical trials have not yet been able to demonstrate the same protective effects from taking supplements. It is difficult to estimate how many Canadians achieve an adequate level of consumption, but it seems reasonable to assume that many Canadians could benefit from substantially increasing their intake of vegetables and fruit.

    Cannabis is the most widely used illicit drug in the United States and Europe. In recent years, a range of new substances with cannabis-like effects-known as synthetic cannabinoids (SCs)-have suddenly burst on the drug scene. However, there is limited information about the clinical hazards linked to the use of these emerging substances. This review summarizes the literature to date relating the health effects of SCs. A systematic literature review of original case studies was performed using PubMed and Web of Science (January 1980-July 2015). Only articles in which a drug screening was reported were included in this review. Forty-six articles meeting the inclusion criteria were included in this review, reporting data on 114 patients who went to hospital emergency departments after exposure to SCs. The majority of patients were adolescent or young adult males (14-25 years; 24.5 ± 10.1 years). The most common route of administration was smoking. The SCs most involved were John William Huffman (JWH) derivatives, followed by XRL-11, ADB-PINACA, AM-2201, MAM-2201, and 5F-PB-22. This analysis showed that the use of these substances may cause minor and moderate side effects similar to those of cannabis intoxication, including tachycardia, nausea, somnolence, hallucinations, paranoia, xerostomia, and injected conjunctivae among others. However, atypical cannabis intoxication effects and worse complications (such as renal injuries, aggressiveness, cerebral ischemia, myocardial infarction, etc.) were also observed, which led to a significant morbidity were also observed. Some SCs were highlighted as being involved in 24 cases of deaths. In this review, the nature and frequency of the signs and symptoms of SC poisoning were estimated in order to inform health professionals about the health risks of these new and emerging substances.

    Australian mental health nurses will need to care with consumers of mental health services, within the domains of recovery. However, in acute inpatient mental health settings, nurses are without a clear description of how to be recovery-oriented. The intent of this qualitative study was to ask nurses to reflect on and describe current practice within acute inpatient services that are not overtly recovery-oriented. Results show that nurses can identify recovery and articulate with pragmatic clarity how to care within a recovery-oriented paradigm. Pragmatic modes of care described by nurses support using "champions" to assist with eventual system transformation in the delivery of mental health services.

    The Space Radiation Standing Review Panel (from here on referred to as the SRP) was impressed with the strong research program presented by the scientists and staff associated with NASA's Space Radiation Program Element and National Space Biomedical Research Institute (NSBRI). The presentations given on-site and the reports of ongoing research that were provided in advance indicated the potential Risk of Acute and Late Central Nervous System Effects from Radiation Exposure (CNS) and were extensively discussed by the SRP. This new data leads the SRP to recommend that a higher priority should be placed on research designed to identify and understand these risks at the mechanistic level. To support this effort the SRP feels that a shift of emphasis from Acute Radiation Syndromes (ARS) and carcinogenesis to CNS-related endpoints is justified at this point. However, these research efforts need to focus on mechanisms, should follow pace with advances in the field of CNS in general and should consider the specific comments and suggestions made by the SRP as outlined below. The SRP further recommends that the Space Radiation Program Element continue with its efforts to fill the vacant positions (Element Scientist, CNS Risk Discipline Lead) as soon as possible. The SRP also strongly recommends that NASA should continue the NASA Space Radiation Summer School. In addition to these broad recommendations, there are specific comments/recommendations noted for each risk, described in detail below.

    2012-07-01

    Comparative effectiveness research (CER) represents an evolution in clinical decision-making research that allows for the study of heterogeneous groups of patients with complex diseases processes. It has foundations in decision science, reliability science, and health care policy research. Health care finance will increasingly rely on CER for guidance in the coming years. There is increasing awareness of the importance of decreasing unwarranted variation in health care delivery. In the past 7 years, Geisinger Health System has performed broad reengineering of its acute episodic and chronic care delivery models utilizing macrosystem-level application of CER principles. These provider-driven process initiatives have resulted in significant improvement across all segments of care delivery, improved patient outcomes, and notable cost containment. These programs have led to the creation of novel pricing models, and when "hardwired" throughout a care delivery system, they can lead to correct medical decision making by 100% of providers in all patient encounters. Neurosurgery as a specialty faces unique challenges and opportunities with respect to broad adoption and application of CER techniques.

    The most common health problems in Nghi Trong in Vietnam include reproductive tract infections, children's diseases such as diarrhea, and acute bronchitis. Reproductive tract infections take place because of unsanitary water and acute bronchitis is rampant because of the cold weather. Although no HIV/AIDS cases have been reported in the commune, the Nghi Trong Commune Health Center (CHC) is making every effort to prevent HIV infection while providing other services. Under the Japan International Cooperation Agency (JICA) project, information, education and communication activities have been implemented in the district. These activities are important because they have been helping commune people identify and understand common health problems, how to prevent them, and how to get timely treatment. It is not only temporary, but it is permanently effective in health development. In addition, health staff workers at the CHCs are benefiting from the training program provided by the JICA project. More commune people are also visiting the CHCs for examination and treatment.

    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.

    The benefits that physical exercise confers on cardiovascular health are well known, whereas the notion that physical exercise can also improve cognitive performance has only recently begun to be explored and has thus far yielded only controversial results. In the present study, we used a sample of young male subjects to test the effects that a single bout of aerobic exercise has on learning. Two tasks were run: the first was an orientation discrimination task involving the primary visual cortex, and the second was a simple thumb abduction motor task that relies on the primary motor cortex. Forty-four and forty volunteers participated in the first and second experiments, respectively. We found that a single bout of aerobic exercise can significantly facilitate learning mechanisms within visual and motor domains and that these positive effects can persist for at least 30 minutes following exercise. This finding suggests that physical activity, at least of moderate intensity, might promote brain plasticity. By combining physical activity-induced plasticity with specific cognitive training-induced plasticity, we favour a gradual up-regulation of a functional network due to a steady increase in synaptic strength, promoting associative Hebbian-like plasticity.

    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 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).

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

    Full Text Available In modern world, living without radiation is impossible. Radiation is defined as ?energy transmitted through space as waves or particles? and also determined as ?particles or waves emitted from the nucleus of unstable radioactive atoms to become stable? Mainly two types of radiation are exist; ionising radiation and non-ionising radiation. Ionising radiation is consist of alpha, beta particules, neutrons, x rays and gamma rays. Ionising radiation which can be measured by ion chambers, geiger-Mueller detectors, Scintillation Counters, fluorescent counters etc. Has harmfull effects on human health in levels of molecular, cellular, tissue, organs and organ systems. These harmfull effects can also be named somatic and genetic. One of the most encountered problem is ?Acute Radiation Syndrom? which has three sub syndroms called haematopoetic syndrom, gastrointestinal syndrom and neurovascular syndrom. Exposure time, distance and armorisation are the key elements of protection from radiation. [TAF Prev Med Bull 2005; 4(4.000: 199-208

  9. Do pollution time-series studies contain uncontrolled or residual confounding by risk factors for acute health events?

    Acute health effects from air pollution are based largely on weak associations identified in time-series studies comparing daily air pollution levels to daily mortality. Much of this mortality is due to cardiovascular disease. Time-series studies have many potential limitations, but are not thought to be confounded by traditional cardiovascular risk factors (e.g., smoking status or hypertension) because these chronic risk factors are not obviously associated with daily pollution levels. However, acute psychobehavioral variants of these risk factors (e.g., smoking patterns and episodes of stress on any given day) are plausible confounders for the associations observed in time-series studies, given that time-series studies attempt to predict acute rather than chronic health outcomes. There is a fairly compelling literature on the strong link between cardiovascular events and daily "triggers" such as stress. Stress-related triggers are plausibly associated with daily pollution levels through surrogate stressors such as ambient temperature, daily workload, local traffic congestion, or other correlates of air pollution. For example, variables such as traffic congestion and industrial activity increase both stress-related health events and air pollution, suggesting the potential for classical confounding. Support for this argument is illustrated through examples of the well-demonstrated relationship between emotional stress and heart attack/stroke.

    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.

    A recent clinical trial suggests that printed (PDS) and computer decision support (CDS) interventions are safe and effective in reducing antibiotic use in acute bronchitis relative to usual care (UC). Our aim was to evaluate the cost-effectiveness of decision support interventions in reducing antibiotic use in acute bronchitis. We conducted a clinical trial-based cost-effectiveness analysis comparing UC, PDS and CDS for management of acute bronchitis. We assumed a societal perspective, 5-year program duration and 30-day time horizon. The U.S. population aged 13-64 years presenting with acute bronchitis in the ambulatory setting. Printed and computer decision support interventions relative to usual care. Cost per antibiotic prescription safely avoided. In the base case, PDS dominated UC and CDS, with lesser total costs (PDS: $2,574, UC: $2,768, CDS: $2,805) and fewer antibiotic prescriptions (PDS: 3.79, UC: 4.60, CDS: 3.95) per patient over 5 years. In one-way sensitivity analyses, PDS dominated UC across all parameter values, except when antibiotics reduced work loss by ≥ 1.9 days or the probability of hospitalization within 30 days was ≥ 0.9 % in PDS (base case: 0.2 %) or ≤ 0.4 % in UC (base case: 1.0 %). The dominance of PDS over CDS was sensitive both to probability of hospitalization and plausible variation in the adjusted odds of antibiotic use in both strategies. A PDS strategy to reduce antibiotic use in acute bronchitis is less costly and more effective than both UC and CDS strategies, although results were sensitive to variation in probability of hospitalization and the adjusted odds of antibiotic use. This simple, low-cost, safe, and effective intervention would be an economically reasonable component of a multi-component approach to address antibiotic overuse in acute bronchitis.

    The toxic effects of mercury are known to be complex with specific enzyme inhibitions and subsequent oxidative stress adding to the damaging effects. There are likely other factors involved, such as the development of impaired metal ion homeostasis and depletion of thiol and selenium based metabolites such as cysteine and selenium. Much of the toxicity of mercury occurs at the intracellular level via binding of Hg(2+) to thiol groups in specific proteins. Therefore, amelioration of mercury toxicity by the use of chelation would likely be enhanced by the use of a chelator that could cross the cell membrane and the blood brain barrier. It would be most favorable if this compound was of low toxicity, had appropriate pharmacokinetics, bound and rendered mercury cation non-toxic and had antioxidant properties. Herein we report on such a chelator, N,N'-bis(2-mercaptoethyl)isophthalamide (NBMI), and, using an animal model, show that it prevented the toxic effects associated with acute exposure induced by injected mercury chloride.

    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.

    Experimental studies have shown that hyperthermia is a determinant of poor outcome after ischemic stroke. Clinical studies evaluating the effect of temperature on poststroke outcome have, however, been limited by small sample sizes. We sought to evaluate the effect of temperature and timing of hyperthermia on outcome after ischemic stroke. Data of 5305 patients in acute stroke trials from the Virtual International Stroke Trials Archive (VISTA) data set were analyzed. Data for temperatures at baseline, eighth, 24th, 48th, and 72nd hours, and seventh day were assessed in relation to outcome (poor versus good) based on the modified Rankin Scale at 3 months. Hyperthermia was defined as temperature >37.2 degrees C and poor outcome as 90-day modified Rankin Scale >2. Hazard ratios with 95% CIs were reported for hyperthermia in relation to the outcome. Logistic regression models, in relation to hyperthermia, were fitted for a set of preselected covariates at different time points to identify predictors/determinants of hyperthermia. The average age of patients was 68.0+/-11.9 years, 2380 (44.9%) were females, and 42.3% (2233) received thrombolysis using recombinant tissue plasminogen activator. After adjustment, hyperthermia was a statistically significant predictor of poor outcome. The hazard ratios (95% CI) for poor outcome in relation to hyperthermia at different time points were: baseline 1.2 (1.0 to 1.4), eighth hour 1.7 (1.2 to 2.2), 24th hour 1.5 (1.2 to 1.9), 48th hour 2.0 (1.5 to 2.6), 72nd hour 2.2 (1.7 to 2.9), and seventh day 2.7 (2.0 to 3.8). Gender, stroke severity (National Institutes of Health Stroke Scale score >16), white blood cell count, and antibiotic use were significantly associated with hyperthermia (Pacute ischemic stroke, is associated with a poor clinical outcome. The later the hyperthermia occurs within the first week, the worse the prognosis. Severity of stroke and inflammation are important determinants of hyperthermia after ischemic stroke

    Full Text Available Background Noise pollution is of particular importance due to the physical and psychological effects on humans. Noise is a stressor that affects the autonomic nervous system and the endocrine system. Noise is also a threat to marine and terrestrial ecosystems. Health risks from noise are correlated with road traffic. In other words, noise health effects are the health consequences of elevated sound levels. Objectives This study aims to determine the effect of noise pollution (near roadways on health issues in Ahvaz, Iran. Materials and Methods In this cross-sectional study, equivalent sound pressure level were measured by sound level meters TES-1353 in 75 locations around 4 roadways, which had a high load of traffic in Ahvaz City during day time. During the study, 820 measurements were recorded at measuring stations, for 7 days per week with 1-hour interval between each measurement. Statistical analysis was carried out by SPSS software. Results According to the research findings, the equivalent sound pressure levels in all stations were 76.28 ± 3.12 dB (Mean ± SD. According to sound measurements and the survey questionnaire, noise pollution is higher than EPA (US Environmental Protection Agency and Iran standard level. Based on result of this study the worst noise health effects were the nervousness and sleep quality during 2012. Conclusions According to the results of this study, with increasing load of traffic, there is an increasing need for proper consideration plans to control noise pollution and prevent its effects.

    Since 2007 to address a high burden, integration of acute malnutrition has been promoted in Niger. This paper studies factors that influenced the integration process of acute malnutrition into the Niger national health system.We used qualitative methods of observation, key informant interviews and focus group discussions at national level, two districts and nine communities selected through convenience sampling, as well as document review. A framework approach constructed around the problem, intervention, adoption system, health system characteristics and broad context guided the analysis. Data were recorded on paper, transcribed in a descriptive record, coded by themes deduced by building on the framework and triangulated for comprehensiveness.Key facilitating factors identified were knowledge and recognition of the problem helped by accurate information; effectiveness of decentralized continuity of care; compatibility with goals, support and involvement of health actors; and leadership for aligning policies and partnerships and mobilizing resources within a favourable political context driven by multisectoral development goals. Key hindering factors identified were not fully understanding severity, causes and consequences of the problem; limited utilization and trust in health interventions; high workload, and health worker turnover and attrition; and high dependence on financial and technical support based on short-term emergency funding within a context of high demographic pressure.The study uncovered influencing factors of integrating acute malnutrition into the national health system and their complex dynamics and relationships. It elicited the need for goal-oriented strategies and alignment of health actors to achieve sustainability, and systems thinking to understand pathways that foster integration. We recommend that context-specific learning of integrating acute malnutrition may expand to include causal modelling and scenario testing to inform strategy

    Teamwork is seen as an important element of patient care in acute hospital settings. The complexity of the journey of care for patients highlights the need for health professionals to collaborate and communicate clearly with each other. Health organizations in western countries are committed to improving patient safety through education of staff and teamwork education programs have been integral to this focus. There are no current systematic reviews of the experience of health professionals who participate in teamwork education in acute hospital settings. The objective of this systematic review was to search for the best available evidence on the experiences of health professionals who participate in teamwork education in acute hospital settings. This review considered studies reporting on experiences of registered health professionals who work in acute hospitals. This included medical, nursing and midwifery and allied health professionals. The focus of the meta-synthesis was the experiences and reflections of health professionals who were involved in teamwork education in acute hospital settings. The geographical context for this review was acute hospitals in rural or metropolitan settings in Australia and overseas countries. The review focused on the experiences of health professionals who work in acute hospitals and participated in teamwork education programs. This review considered studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research.In the absence of research studies, other text such as opinion papers, discussion papers and reports were considered. Studies published in English and from 1990 to 2013 were included in this review. The literature search for relevant papers occurred between 13 September and 26 October 2013. A three-step search strategy was utilized in this review. The databases searched were PubMed, CINAHL, Embase and Scopus. The

    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.

    Personalised care planning is argued for but there is a need to know more about what the plans actually contain. To describe the content of person-centred health, plans documented at three healthcare levels for patients with acute coronary syndrome. Patients with acute coronary syndrome aged under 75 years and admitted to two coronary care units at a university hospital were enrolled in the study. This retrospective descriptive study documented 89 person-centred health plans at three healthcare levels: hospital, outpatient and primary care. In total, 267 health plans were reviewed and a quantitative content analysis conducted. The health plans included commonly formulated goals, patients' own resources and support needed. The health plan goals were divided into three categories: lifestyle changes, illness management and relational activities. The most frequently reported goal for better health was increased physical activity, followed by social life/leisure activities and return to paid professional work. In order to reach the goals, patients identified three ways: own resources, family and social support and healthcare system, in total three categories. The most frequently reported own capability was self-motivation. Spouses and children were important sources of family and social support. The most frequently reported healthcare support was cardiac rehabilitation. In traditional care and treatment plans devised by health professionals, patient goals often comprise behavioural changes. When patients identify their own goals and resources with the help of professionals, they include maintaining social relations and being able to return to important activities such as work.

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

    Recovery-oriented care acknowledges the unique journey that consumers lead with the aim of regaining control of their lives in order to live a good life. Recovery has become a dominant policy-directed model of many mental health care organizations, but in older-adult acute mental health inpatient settings, nurses do not have a clear description of how to be recovery-oriented. The aims of this study were to determine the extent to which elements of existing nursing practice resemble the domains of recovery-oriented care and provide a baseline understanding of practice in preparation for transformation to recovery-oriented mental health care provision. An exploratory, qualitative research design was used to meet the research aims. A purposive sample of mental health nurses (N = 12) participated in focus groups in three older-adult inpatient settings in Australia. A general inductive approach was used to analyze the qualitative data. The mental health nurses in this study readily discussed aspects of their current practice within the recovery domains. They described pragmatic ways to promote a culture of hope, collaborative partnerships, meaningful engagement, autonomy and self-determination, and community participation and citizenship. Nurses also discussed challenges and barriers to recovery-oriented care in older-adult acute mental health settings. This study identified a reasonable baseline understanding of practice in preparation for transformation to recovery-oriented older-adult mental healthcare provision. A concerted drive focused on recovery education is required to effectively embed a recovery-orientated paradigm into older-adult mental health settings.

    Early reopening of the occluded artery is, thus, important in ischemic stroke, and it has been calculated that 2 million neurons die every minute in an ischemic stroke if no effective therapy is given; therefore, "Time is Brain." 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. The neuroprotective drug citicoline has been extensively studied in clinical trials with volunteers and more than 11,000 patients with various neurologic disorders, including acute ischemic stroke (AIS). The conclusion is that citicoline is safe to use and may have a beneficial effect in AIS patients and most beneficial in less severe stroke in older patients not treated with recombinant tissue plasminogen activator. No other neuroprotective agent had any beneficial effect in confirmative clinical trials or had any positive effect in the subgroup analysis. Citicoline is the only drug that in a number of different clinical stroke trials continuously had some neuroprotective benefit.

    Tea has historically been associated with mood and performance benefits, such as relaxation and concentration. This review summarizes the research on the acute effects of tea, and its ingredients theanine and caffeine, on attention and mood. Consistent with abundant research on the benefits of caffeine, the performance benefits of tea were identified in a number of studies, with particularly consistent evidence for improved attention. Tea consumption also consistently improved self-reported alertness and arousal, whereas effects on pleasure or relaxation were less consistent. In addition to the research on caffeine in real-life performance, 2 recent studies have provided a broader perspective on tea's effects on psychological function in that they showed beneficial effects in related areas such as work performance and creativity. These studies showed the validity of laboratory findings by supporting the idea that tea consumption has acute benefits on both mood and performance in real-life situations.

    Pharmacologic and physiologic effects of snuff and chewing tobacco include the gamut of cardiovascular, endocrinologic, neurologic, and psychological effects that are associated with nicotine. A review of studies appearing in the scientific literature involving various populations and approaches indicates that the use of snuff or chewing tobacco is associated with a variety of serious adverse effects and especially with oral cancer. The studies suggest that snuff and chewing tobacco also may affect reproduction, longevity, the cardiovascular system, and oral health. The Council on Scientific Affairs concludes there is evidence demonstrating that use of snuff or chewing tobacco is associated with adverse health effects such as oral cancer, urges the implementation of well-planned and long-term studies that will further define the risks of using snuff and chewing tobacco, and recommends that the restrictions applying to the advertising of cigarettes also be applied to the advertising of snuff and chewing tobacco.

    From May to June 1999, 3,920 ethnic Albanians from Kosovo arrived in Australia as part of Operation Safe Haven. These people were evacuated from refugee camps in the former Yugoslav Republic of Macedonia. Initial processing in Australia occurred at East Hills Reception Centre, and accommodation for the duration of stay was provided in eight Haven Centres in five States. The arrival of a large number of refugees in a short time frame is unprecedented in Australia. A health surveillance system was developed and critical health data were collected to assess health status and needs, plan care, monitor for potential outbreaks of communicable diseases, track service use, to meet international reporting requirements and document our response to this crisis. In this article the health surveillance system is evaluated and suggestions are offered for the formulation of specific guidelines necessary for health surveillance in acute settings.

    Therapeutic interpersonal relationships are the primary component of all health care interactions that facilitate the development of positive clinician–patient experiences. 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.

    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{sup 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{sup 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.

    Despite the tremendous increase in the number of modern health institutions, traditional medical practices still remain alternative places of health care service delivery and important sites for disease notification in the disease surveillance system. The objectives of this study are to describe the patterns and factors associated with health care seeking behavior of parents and care takers with acute flaccid paralysis child and see how the traditional practice affect the surveillance system. A cross-sectional descriptive study was conducted to assess the health seeking behavior of parents with an acute flaccid paralysis child. Data were collected throughout the country as a routine surveillance program. Of 1299 families analyzed, 907(69.3%) of families with AFP child first went to health institutions to seek medical care, while. 398 (30.7%) of parents took their child first to other traditional sites, including holy water sites (11.8%), traditional healers (9.1%) and prayer places (5.4%). Over half of the parents with AFP child reported practicing home measures before first seeking health service from modern health institutions. Home measures (OR, 0.1202, 95% CI 0.0804-0.1797), decision by relatives (OR, 0.5595, 95% CI 0.3665-0.8540) and More than 10km distance from health facility (OR, 0.5962, 95% CI, 0.4117-0.8634) were significantly associated to first seeking health service from health institutions (p<0.05). Program strategies must certainly be developed to expand and capture all traditional sites in the surveillance network, and intensify sensitization and active surveillance visit in these areas.

    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.

    Full Text Available Psychiatric nurse practitioners (PNPs working with mental health care users presenting with acute symptoms work in a complex environment. This environment is characterised by mental health care users who may present with a history of violence, sexual assault and substance misuse.The objectives of this study were twofold: firstly, to explore and describe the experiences of PNPs working with mental health care users (MHCUs presenting with acute symptoms; and secondly, to make recommendations for the advanced PNPs to facilitate promotion of the mental health of PNPs with reference to nursing practice, research and education.A qualitative, explorative, descriptive and contextual design was used. The target population was PNPs working with MHCUs presenting with acute symptoms in a public mental health care institution in Gauteng. Data were collected by means of four focus group interviews involving 21 PNPs. The researcher made use of drawings, naïve sketches and field notes for the purpose of data triangulation. Data were analysed in accordance with Tesch’s method of open coding.The three themes that emerged were: PNPs experienced working with these MHCUs as entering an unsafe world where care became a burden; they experienced negative emotional reactions and attitudes towards these MHCUs that compromised quality nursing care; and they made a plea for a nurturing environment that would enhance quality nursing care.The PNPs suggest skills and competency development, organisational support, and a need for external resources. Creation of a positive environment and mobilisation of resources as well as the identification and bridging of obstacles are essential in the promotion of the overall wellbeing and mental health of PNPs.

    Distress intolerance (an individual's perceived or actual inability to tolerate distressing psychological or physiological states) is associated with cannabis use. It is unknown whether a biobehavioral index of distress intolerance, breath-holding duration, is acutely influenced (increased or decreased) by cannabis. Such information may further inform understanding of the expression of psychological or physiological distress postcannabis use. This within-subjects study examined whether smoked marijuana with 2.7%-3.0% delta-9-tetrahydrocannabinol (THC), relative to placebo, acutely changed duration of breath holding. Participants (n = 88; 65.9% male) were nontreatment-seeking frequent cannabis users who smoked placebo or active THC cigarette on two separate study days and completed a breath-holding task postsmoking. Controlling for baseline breath-holding duration and participant sex, THC produced significantly shorter breath-holding durations relative to placebo. There was a significant interaction of drug administration × frequency of cannabis use, such that THC decreased breath-holding time among less frequent but not among more frequent users. Findings indicate that cannabis may exacerbate distress intolerance (via shorter breath-holding durations). As compared to less frequent cannabis users, frequent users display tolerance to cannabis' acute effects including increased ability to tolerate respiratory distress when holding breath. Objective measures of distress intolerance are sensitive to contextual factors such as acute drug intoxication, and may inform the link between cannabis use and the expression of psychological distress.

    The complex process of discharging patients from acute care to community care requires a multifaceted interaction between all health care providers and patients. 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. 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. 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. 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 teaching unit and occurred on a daily basis between the multidisciplinary team. To help facilitate provider-patient communication, electronic transfer of care summaries were suggested as a potential solution. To help role clarity, a discharge coordinator and/or liaison was suggested. Communication can be enhanced through use of electronic discharge summaries, bullet rounds, and implementation of a discharge coordinator(s). The findings from this study can be used to aid future researchers in devising appropriate

    Cigarette smoking is common despite adverse health effects. Nicotine's effects on learning may contribute to addiction by enhancing drug-context associations. Effects of nicotine on learning could be direct or could occur by altering systems that modulate cognition. Because thyroid signaling can alter cognition and nicotine/smoking may change thyroid function, nicotine could affect learning through changes in thyroid signaling. These studies investigate the functional contributions of thyroid receptor (TR) subtypes β and α1 to nicotine-enhanced learning and characterize the effects of acute nicotine and learning on thyroid hormone levels. We conducted a high throughput screen of transcription factor activity to identify novel targets that may contribute to the effects of nicotine on learning. Based on these results, which showed that combined nicotine and learning uniquely acted to increase TR activation, we identified TRs as potential targets of nicotine. Further analyses were conducted to determine the individual and combined effects of nicotine and learning on thyroid hormone levels, but no changes were seen. Next, to determine the role of TRβ and TRα1 in the effects of nicotine on learning, mice lacking the TRβ or TRα1 gene and wildtype littermates were administered acute nicotine prior to fear conditioning. Nicotine enhanced contextual fear conditioning in TRα1 knockout mice and wildtypes from both lines but TRβ knockout mice did not show nicotine-enhanced learning. This finding supports involvement of TRβ signaling in the effect of acute nicotine on hippocampus-dependent memory. Acute nicotine enhances learning and these effects may involve processes regulated by the transcription factor TRβ.

    The in vivo effect of Solcoseryl on the antitumour activity and acute toxicity of some antineoplastic drugs was examined. It was found that Solcoseryl does not inhibit the antineoplastic effectiveness of the drugs against transplantable P 388 leukaemia in mice. Studies of the effect of Solcoseryl on acute toxicity of selected antineoplastic drugs in mice revealed that the biostimulator could exert a modifying influence. The prior administration of Solcoseryl significantly decreases the acute toxicity of methotrexate but has no effect on acute toxicity of 5-fluorouracil, increases the acute toxicity of bleomycin and vinblastine and has no effect on acute toxicity of methotrexate and mitoxantron. On the other hand, Solcoseryl administered simultaneously with the antineoplastic drugs increases acute toxicity of 5-fluorouracil, bleomycin and mitoxantron. The protective effect of the biostimulator noted exclusively against acute toxicity of 5-fluorouracil was also observed after multiple administration of this anticancer drug.

    2014-05-01

    With the rapid increase in use of electronic nicotine delivery systems (ENDS), such as electronic cigarettes (e-cigarettes), users and non-users are exposed to the aerosol and product constituents. This is a review of published data on the human health effects of exposure to e-cigarettes and their components. Literature searches were conducted through September 2013 using multiple electronic databases. Forty-four articles are included in this analysis. E-cigarette aerosols may contain propylene glycol, glycerol, flavourings, other chemicals and, usually, nicotine. Aerosolised propylene glycol and glycerol produce mouth and throat irritation and dry cough. No data on the effects of flavouring inhalation were identified. Data on short-term health effects are limited and there are no adequate data on long-term effects. Aerosol exposure may be associated with respiratory function impairment, and serum cotinine levels are similar to those in traditional cigarette smokers. The high nicotine concentrations of some products increase exposure risks for non-users, particularly children. The dangers of secondhand and thirdhand aerosol exposure have not been thoroughly evaluated. Scientific evidence regarding the human health effects of e-cigarettes is limited. While e-cigarette aerosol may contain fewer toxicants than cigarette smoke, studies evaluating whether e-cigarettes are less harmful than cigarettes are inconclusive. Some evidence suggests that e-cigarette use may facilitate smoking cessation, but definitive data are lacking. No e-cigarette has been approved by FDA as a cessation aid. Environmental concerns and issues regarding non-user exposure exist. The health impact of e-cigarettes, for users and the public, cannot be determined with currently available data.

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 (Pacetaminophen and placebo was 0.86 (95% CI: 0.62 to 1.2), with no statistical significance (P=0.27). Acetaminophen was revealed to have some favorable influence in body temperature reduction in acute stroke, but showed no important effect on improving functional outcome and reducing adverse events of patients. What is already known on this subject? Paracetamol (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.

    The need to focus on patient safety and improve the quality and consistency of medical care in acute hospital settings has been highlighted in a number of UK and international reports. When patients on a hospital ward become acutely unwell there is often a window of opportunity for staff, patients and relatives to contribute to the 'rescue' process by intervening in the trajectory of clinical deterioration. This paper explores the social and institutional processes associated with the practice of rescue, and implications for the implementation and effectiveness of rapid response systems (RRSs) within acute health care. An ethnographic case study was conducted in 2009 in two UK hospitals (focussing on the medical directorates in each organisation). Data collection involved 180 h of observation, 35 staff interviews (doctors, nurses, health care assistants and managers) and documentary review. Analysis was informed by Bourdieu's logic of practice and his relational concept of the 'field' of the general medical ward. Three themes illustrated the nature of rescue work within the field and collective rules which guided associated occupational distinction practices: (1) the 'dirty work' of vital sign recording and its distinction from diagnostic (higher order) interpretive work; (2) the moral order of legitimacy claims for additional help; and (3) professional deference and the selective managerial control of rescue work. The discourse of rescue provided a means of exercising greater control over clinical uncertainty. The acquisition of 'rescue capital' enabled the social positioning of health care assistants, nurses and doctors, and shaped use of the RRS on the wards. Boundary work, professional legitimation and jurisdictional claims defined the social practice of rescue, as clinical staff had to balance safety, professional and organisational concerns within the field. This paper offers a nuanced understanding of patient safety on the front-line, challenging notions of

    Conditions with chronically elevated glucocorticoid levels are usually associated with declarative memory deficits. Considerable evidence suggests that long-term glucocorticoid exposure may cause cognitive impairment via cumulative and long-lasting influences on hippocampal function and morphology. However, because elevated glucocorticoid levels at the time of retention testing are also known to have direct impairing effects on memory retrieval, it is possible that such acute hormonal influences on retrieval processes contribute to the memory deficits found with chronic glucocorticoid exposure. To investigate this issue, we examined memory functions and hippocampal volume in 24 patients with rheumatoid arthritis who were treated either chronically (5.3 +/- 1.0 years, mean +/- SE) with low to moderate doses of prednisone (7.5 +/- 0.8 mg, mean +/- SE) or without glucocorticoids. In both groups, delayed recall of words learned 24 h earlier was assessed under conditions of either elevated or basal glucocorticoid levels in a double-blind, placebo-controlled crossover design. Although the findings in this patient population did not provide evidence for harmful effects of a history of chronic prednisone treatment on memory performance or hippocampal volume per se, acute prednisone administration 1 h before retention testing to either the steroid or nonsteroid group impaired word recall. Thus, these findings indicate that memory deficits observed under chronically elevated glucocorticoid levels result, at least in part, from acute and reversible glucocorticoid effects on memory retrieval.

    Full Text Available OBJECTIVE: To investigate to what extent various oral health variables are associated with taste ability in acutely hospitalized elderly. BACKGROUND: Impaired taste may contribute to weight loss in elderly. Many frail elderly have poor oral health characterized by caries, poor oral hygiene, and dry mouth. However, the possible influence of such factors on taste ability in acutely hospitalized elderly has not been investigated. MATERIALS AND METHODS: The study was cross-sectional. A total of 174 (55 men acutely hospitalized elderly, coming from their own homes and with adequate cognitive function, were included. Dental status, decayed teeth, oral bacteria, oral hygiene, dry mouth and tongue changes were recorded. Growth of oral bacteria was assessed with CRT® Bacteria Kit. Taste ability was evaluated with 16 taste strips impregnated with sweet, sour, salty and bitter taste solutions in 4 concentrations each. Correct identification was given score 1, and maximum total taste score was 16. RESULTS: Mean age was 84 yrs. (range 70-103 yrs.. Total taste score was significantly and markedly reduced in patients with decayed teeth, poor oral hygiene, high growth of oral bacteria and dry mouth. Sweet and salty taste were particularly impaired in patients with dry mouth. Sour taste was impaired in patients with high growth of oral bacteria. CONCLUSION: This study shows that taste ability was reduced in acutely hospitalized elderly with caries activity, high growth of oral bacteria, poor oral hygiene, and dry mouth. Our findings indicate that good oral health is important for adequate gustatory function. Maintaining proper oral hygiene in hospitalized elderly should therefore get high priority among hospital staff.

    In 2013, the World Health Organization (WHO) published new guidelines for the management of conditions specifically related to stress, including symptoms of acute stress, bereavement, and post-traumatic stress disorder (PTSD). It is important to evaluate potential challenges for the implementation of these guidelines in low-resource settings, however, there is a dearth of research in this area. The current qualitative study aimed to assess perspectives on the feasibility and acceptability of the new guidelines in four clinics that provide mental health services in post-conflict northern Uganda. In-depth interviews were conducted with 19 mental health-care providers and program developers in northern Uganda to address three major research objectives: (1) describe the current standard practices and guidelines used for treating conditions related to stress in Uganda; (2) identify barriers and challenges associated with implementing the new WHO guidelines; and (3) identify and describe potential strategies for overcoming these barriers and challenges. An emergent thematic analysis was used to develop a coding scheme for the transcribed interviews. Practices for managing conditions related to stress included group psychological interventions, psychoeducation, and medication for clients with severe signs and symptoms. Several themes were identified from the interviews on barriers to guideline implementation. These included (1) a lack of trained and qualified mental health professionals to deliver WHO-recommended psychological interventions; (2) a perception that psychological interventions developed in high-income countries would not be culturally adaptable in Uganda; and (3) reluctance about blanket statements regarding medication for the management of acute stress symptoms and PTSD. Identified strategies for overcoming these barriers included (1) training and capacity building for current mental health staff; (2) a stepped care approach to mental health services; and

    In the EU 27 countries about 100 million persons are exposed to road traffic noise above 55 dB (LDEN) according to the European Environment Agency. Exposure to railway noise affects 16 million individuals, aircraft noise 4 million and industry noise 1 million persons. Although the proportion of people reporting to be annoyed by noise exposure is substantial, health effects of noise is rarely an issue in general practitioners' consultations. According to stress models chronic noise exposure results in an increased allostatic load by direct physiological responses as well as psychological stress responses including sleep disturbances. In relation to acute and chronic noise exposure an increase of blood pressure was observed in epidemiological studies. An association between ischemic heart diseases and noise exposure was observed in various studies. However, the data is less consistent for other cardiovascular diseases and for cognitive effects in children. The association between metabolic syndrome and noise has rarely been investigated so far. Recently an association between road traffic noise and diabetes was observed in a Danish cohort study. Given the plausibility for a noise effect, general practitioners should consider noise exposure in patients with increased cardiometabolic risk.

    AIM: To assess the role of oxygen-derived free radicals and cytokines in the pathogenesis of taurocholic acid-induced acute pancreatitiS, and to evaluate the preventive effects of octreotide towards the development of acute pancreatitis.METHODS: Acute pancreatitis was induced in male New Zealand 50 g/L sodium taurocholate (NaTC) in the pancreatic duct. Shamwas administered subcutaneously before the induction of pancreatitis. Blood was taken from the jugular vein before and at 1, 3, 6, 12 and 24 h after pancreatitis induction.Serum activities of amylase, IL-6 and TNF-α and levels of malonyl dialdehyde (MDA), glutathione (GSH), glutathione peroxidase (GPx), catalase and superoxide dismutase (Mn-,Cu-, and Zn-SOD) in pancreatic tissue were measured.RESULTS: Serum TNF-α and IL-6 levels increased significantly 3 h after the onset of pancreatitis, and then returned to control level. The tissue concentration of MDA was significantly elevated at 24 h, while the GSH level and GP-x, catalase, Mn-SOD, Cu-, Zn-SOD activities were all significantly decreased in animals with pancreatitis as compared to the control. Octreotide pretreatment significantly reversed the changes in cytokines and reactive oxygen metabolites. Octreotide treatment did not alter the serum amylase activity and did not have any beneficial effects on the development of histopathological changes.CONCLUSION: Oxygen-derived free radicals and proinflammatory cytokines are generated at an early stage of NaTc-induced acute pancreatitis in rabbits. Prophylactic octreotide treatment can prevent release of cytokines and generation of reactive oxygen metabolites, but does not have any beneficial effects on the development of necrotizing pancreatitis.

    Pharmaceuticals and personal care products (PPCPs), as emerging contaminants, have been detected in various environmental matrices and caused adverse effects on human health and the ecosystem. But water quality criterias (WQCs) of PPCPs for protecting aquatic environment are lacking, which hinders the environmental management of these emerging contaminants. In the present study, in order to support their WQC derivation, acute and chronic hazardous concentrations for 5% of species (HC5s) of some frequently detected PPCPs in China were calculated based on acute and chronic species sensitivity distributions (SSDs), respectively, using both parametric (log-normal and log-logistic) and nonparametric bootstrap approaches. The groups of aquatic species used in SSDs included planktons, zooplanktons, invertebrates and vertebrates. Acute and chronic predicted no effect concentrations (PNECs) were derived from the HC5s. The acute PNECs of the selected PPCPs were in a range from 1.1 to 4993μg/L. While the chronic PNECs were one or two orders of magnitude lower than the acute PNECs, with a range from 0.02 to 298μg/L. Among these PPCPs, the compound with the highest acute effect on the aquatic environment was clarithromycin while erythromycin was the one with the highest chronic toxicity effect. Among the studied PPCPs, erythromycin caused a relatively higher aquatic ecological risk in China. This study helps derive WQCs of PPCPs in the aquatic environment, which is essential for environmental managment of these emerging contaminants. Copyright © 2017. Published by Elsevier Inc.

    Physical activity is associated with reduced risk of several cancers, including aggressive prostate cancer. The mechanisms mediating the effects are not yet understood; among the candidates are modifications of endogenous hormone levels. Long-term exercise is known to reduce serum levels of growth stimulating hormones. In contrast, the endocrine effects of acute endurance exercise include increased levels of mitogenic factors such as GH and IGF-1. It can be speculated that the elevation of serum growth factors may be detrimental to prostate cancer progression into malignancy. The incentive of the current study is to evaluate the effect of acute exercise serum on prostate cancer cell growth. We designed an exercise intervention where 10 male individuals performed 60 minutes of bicycle exercise at increasing intensity. Serum samples were obtained before (rest serum) and after completed exercise (exercise serum). The established prostate cancer cell line LNCaP was exposed to exercise or rest serum. Exercise serum from 9 out of 10 individuals had a growth inhibitory effect on LNCaP cells. Incubation with pooled exercise serum resulted in a 31% inhibition of LNCaP growth and pre-incubation before subcutaneous injection into SCID mice caused a delay in tumor formation. Serum analyses indicated two possible candidates for the effect; increased levels of IGFBP-1 and reduced levels of EGF. In conclusion, despite the fear of possible detrimental effects of acute exercise serum on tumor cell growth, we show that even the short-term effects seem to add to the overall beneficial influence of exercise on neoplasia.

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.

    Indoor air quality can be impacted by hundreds of different chemicals. More than 900 different organic compounds alone have been identified in indoor air. Health effects that could arise from exposure to individual pollutants or mixtures of pollutants cover the full range of acute and chronic effects, including largely reversible responses, such as rashes and irritations, to the irreversible toxic and carcinogenic effects. These indoor contaminants are emitted from a large variety of materials and substances that are widespread components of everyday life. Pacific Northwest Laboratory conducted a search of the peer-reviewed literature on health effects associated with indoor air contaminants for the Bonneville Power Administration to aid the agency in the preparation of environmental documents. Results are reported in two volumes. Volume 1 summarizes the results of the search of the peer-reviewed literature on health effects associated with a selected list of indoor air contaminants. In addition, the report discusses potential health effects of polychlorinated biphenyls and chlorofluorocarbons. All references to the literature reviewed are found in this document Volume 2. Volume 2 provides detailed information from the literature reviewed, summarizes potential health effects, reports health hazard ratings, and discusses quantitative estimates of carcinogenic risk in humans and animals. Contaminants discussed in this report are those that; have been measured in the indoor air of a public building; have been measured (significant concentrations) in test situations simulating indoor air quality (as presented in the referenced literature); and have a significant hazard rating. 38 refs., 7 figs., 23 tabs.

    2003-03-01

    A review was conducted of studies that assessed the effects of acute bouts of physical activity on adults' cognitive performance. Three groups of studies were constituted on the basis of the type of exercise protocol employed. Each group was then evaluated in terms of information-processing theory. It was concluded that submaximal aerobic exercise performed for periods up to 60 min facilitate specific aspects of information processing; however, extended exercise that leads to dehydration compromises both information processing and memory functions. The selective effects of exercise on cognitive performance are explained in terms of Sanders' [Acta Psychol. 53 (1983) 61] cognitive-energetic model.

    There is growing concern about how hydraulic fracturing affects public health because this activity involves handling large volumes of fluids that contain toxic and carcinogenic constituents, which are injected under high pressure through wells into the subsurface to release oil and gas from tight shale formations. The constituents of hydraulic fracturing fluids (HFFs) present occupational health risks because workers may be directly exposed to them, and general public health risks because of potential air and water contamination. Hazard identification, which focuses on the types of toxicity that substances may cause, is an important step in the complex health risk assessment of hydraulic fracturing. This article presents a practical and adaptable tool for the hazard identification of HFF constituents, and its use in the analysis of HFF constituents reported to be used in 2,850 wells in North Dakota between December 2009 and November 2013. Of the 569 reported constituents, 347 could be identified by a Chemical Abstract Service Registration Number (CASRN) and matching constituent name. The remainder could not be identified either because of trade secret labeling (210) or because of an invalid CASRN (12). Eleven public databases were searched for health hazard information on thirteen health hazard endpoints for 168 identifiable constituents that had at least 25 reports of use. Health hazard counts were generated for chronic and acute endpoints, including those associated with oral, inhalation, ocular, and dermal exposure. Eleven of the constituents listed in the top 30 by total health hazard count were also listed in the top 30 by reports of use. This includes naphthalene, which along with benzyl chloride, has the highest health hazard count. The top 25 constituents reportedly used in North Dakota largely overlap with those reported for Texas and Pennsylvania, despite different geologic formations, target resources (oil vs. gas), and disclosure requirements

    Social policy greatly influences the working environment of mental health nurses but in practice can be difficult to translate. Empowerment of service users is one area that is constantly significant in policy, locally and nationally, yet quite difficult to define in practice. This ethnomethodological study explored the practice of 10 mental health nurses working in an acute admissions unit. Through semi-structured interviews, the nurses were asked to discuss the taken-for-granted methods of empowerment with individual service users, their families and with work colleagues. The results were thematically analysed and compared with international findings, which reflected an awareness among mental health nurses of empowering practice in four areas. These were: Working with mental illness, Making connections, Responsibility and Teamworking.

    Full Text Available Accumulating data clearly claimed that Punica granatum L. (pomegranate has several health benefits. Pomegranates can help prevent or treat various disease risk factors including high blood pressure, high cholesterol, oxidative stress, hyperglycemia, and inflammatory activities. It is demonstrated that certain components of pomegranate such as polyphenols have potential antioxidant, anti-inflammatory, and anticarcinogenic effects. The antioxidant potential of pomegranate juice is more than that of red wine and green tea, which is induced through ellagitannins and hydrosable tannins. Pomegranate juice can reduce macrophage oxidative stress, free radicals, and lipid peroxidation. Moreover, pomegranate fruit extract prevents cell growth and induces apoptosis, which can lead to its anticarcinogenic effects. In addition, promoter inhibition of some inflammatory markers and their production are blocked via ellagitannins. In this article, we highlight different studies on the therapeutic effects of pomegranate and their suggested mechanisms of actions.

    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.

    Neurosteroid dehydroepiandrosterone sulfate (DHEAS) has been associated with important brain functions, including neuronal survival, memory, and behavior, showing therapeutic potential in various neuropsychiatric and cognitive disorders. 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. 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 [(3)H]flunitrazepam binding to the mouse brain membranes. DHEAS did not modify the locomotor activity, motor coordination, body weight, and brain [(3)H]flunitrazepam binding of male and female mice. The results failed to demonstrate significant effects of single- and long-term DHEAS treatment on the convulsive susceptibility in both adult and aged mice of both sexes. However, small but significant changes regarding sex differences in the susceptibility to seizures were observed following DHEAS administration to mice. Although our findings suggest that DHEAS treatment might be safe for various potential therapeutic applications in adult as well as in old age, they also support subtle interaction of DHEAS with male and female hormonal status, which may underline observed sex

    Full Text Available Dietary fi bre is a group of food components which is resistant to digestive enzymes and found mainly in cereals, fruits and vegetables. Dietary fi ber and whole grains contain a unique blend of bioactive components including resistant starches, vitamins, minerals, phytochemicals and antioxidants. Dietary fi ber which indigestible in human small intestinal, on the other hand digested completely or partially fermented in the large intestine, is examined in two groups: water-soluble and water insoluble organic compounds. Dietary fi ber can be separated into many different fractions. These fractions include arabinoxylan, inulin, pectin, bran, cellulose, β-glucan and resistant starch. Dietary fi bres compose the major component of products with low energy value that have had an increasing importance in recent years. Dietary fi bres also have technological and functional properties that can be used in the formulation of foods, as well as numerous benefi cial effects on human health. Dietary fi bre components organise functions of large intestine and have important physiological effects on glucose, lipid metabolism and mineral bioavailability. Today, dietary fi bers are known to be protective effect against certain gastrointestinal diseases, constipation, hemorrhoids, colon cancer, gastroesophageal refl ux disease, duodenal ulcer, diverticulitis, obesity, diabetes, stroke, hypertension and cardiovascular diseases. In this review the physicochemical and biological properties of dietary fi bers and their important implications on human health will be investigated.

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

    Full Text Available BACKGROUND: Relapses occur in about 20% of children with acute lymphoblastic leukemia (ALL. Approximately one-third of these children can be cured. Their risk for late effects is high because of intensified treatment, but their health-related quality of life (HRQOL was largely unmeasured. Our aim was to compare HRQOL of ALL survivors with the general population, and of relapsed with non-relapsed ALL survivors. METHODOLOGY/PRINCIPAL FINDINGS: As part of the Swiss Childhood Cancer Survivor Study (SCCSS we sent a questionnaire to all ALL survivors in Switzerland who had been diagnosed between 1976-2003 at age <16 years, survived ≥5 years, and were currently aged ≥16 years. HRQOL was assessed with the Short Form-36 (SF-36, which measures four aspects of physical health and four aspects of mental health. A score of 50 corresponded to the mean of a healthy reference population. We analyzed data from 457 ALL survivors (response: 79%. Sixty-one survivors had suffered a relapse. Compared to the general population, ALL survivors reported similar or higher HRQOL scores on all scales. Survivors with a relapse scored lower in general health perceptions (51.6 compared to those without (55.8;p=0.005, but after adjusting for self-reported late effects, this difference disappeared. CONCLUSION/SIGNIFICANCE: Compared to population norms, ALL survivors reported good HRQOL, even after a relapse. However, relapsed ALL survivors reported poorer general health than non-relapsed. Therefore, we encourage specialists to screen for poor general health in survivors after a relapse and, when appropriate, specifically seek and treat underlying late effects. This will help to improve patients' HRQOL.

    Full Text Available Health promotion is very relevant today. There is a global acceptance that health and social wellbeing are determined by many factors outside the health system which include socioeconomic conditions, patterns of consumption associated with food and communication, demographic patterns, learning environments, family patterns, the cultural and social fabric of societies; sociopolitical and economic changes, including commercialization and trade and global environmental change. In such a situation, health issues can be effectively addressed by adopting a holistic approach by empowering individuals and communities to take action for their health, fostering leadership for public health, promoting intersectoral action to build healthy public policies in all sectors and creating sustainable health systems. Although, not a new concept, health promotion received an impetus following Alma Ata declaration. Recently it has evolved through a series of international conferences, with the first conference in Canada producing the famous Ottawa charter. Efforts at promoting health encompassing actions at individual and community levels, health system strengthening and multi sectoral partnership can be directed at specific health conditions. It should also include settings-based approach to promote health in specific settings such as schools, hospitals, workplaces, residential areas etc. Health promotion needs to be built into all the policies and if utilized efficiently will lead to positive health outcomes.

    Multidisciplinary teamwork is viewed as one of the key processes through which care is managed in the British National Health Service, and yet is often viewed as one of the most problematic. Working in a multidisciplinary team requires many skills, which involves understanding not only one's own role but also the role of other professionals. The aim of this study was to explore nurses' perceptions of multidisciplinary teamwork in acute health-care. Nineteen nurses were interviewed using the critical incident approach to obtain their perceptions of multidisciplinary teamwork. Direct observation was conducted to record interactions between nurses and health-care professionals in multidisciplinary teams. In total, 14 meetings were attended in elder care and orthopaedics and seven in acute medicine. The findings of this study identified three barriers that hindered teamwork: (i) differing perceptions of teamwork; (ii) different levels of skills acquisitions to function as a team member; and (iii) the dominance of medical power that influenced interaction in teams. Thus, education establishments and nursing managers need to ensure that the acquisition of team-playing skills is an integral part of continued professional development.

    It has been clearly acknowledged and well-documented that physical, emotional, and psychological violence is a central theme and an expected workplace hazard for registered nurses working in acute inpatient mental health care facilities. Limited research, however, has focused on how registered nurses have been able to cope within this environment and adequately protect themselves from harm. A critical feminist research project recently explored the lived experience of 13 Australian, female, registered nurses working in a busy metropolitan acute inpatient mental health care facility. "Fear" was exposed as the precursor to violence and aggression, both "fear as experienced by the nurse" and "fear as experienced by the patient." The participants reported experiencing a sense of fear when they could not accurately or confidently anticipate a patient response or reaction. They identified this relationship with fear as being "part of the job" and part of the unpredictable nature of caring for people experiencing complex distortions in thinking and behavior. The participants believed, however, that additional workplace pressures complicated the therapeutic environment, resulting in a distraction from patient care and observation. This distraction could lead to nurse-patient miscommunication and the potential for violence. This article discusses a major theme to emerge from this study, "Better the devil you know!" The theme highlights how mental health nurses cope with violence and why they choose to continue working in this complex care environment.

    The health system in Pakistan is spraining because of increasing cost and demand gravities. The shortage of skilled health care workers is one of the main factors of health issues. There is a need to move away from the dependency of tools such as pen, paper, and human memory to a milieu where patients and health care providers can reliably access and share health information in real time across geographic and health sector boundaries. The purpose of this research is to observe the effect of e-health on the physician-patient relationship and to analyze the capacity of health professionals by noting information and communication technologies usage as indicators. Structured questionnaire was used to gather data from physicians to judge the success and effect of existing e-health policy. Both categorical and Likert scale variables were used. The analysis of data was per.formed using chi-square test and binary logistic regression. Specialist doctors comprised the major proportion of health care professionals in both male and female categories with good knowledge about Internet usage. E-health-based communication does not seem to be gender specific. Logistic regression revealed that busy doctors whose patients are more than 100 per week believe that e-health would significantly strengthen their communication with patients (OR=3.06; 95% CI=1.05- 8.87). Among other significant impacts of e-health include reduced consultation period and time of diagnosis. E-health technology can play a crucial role in controlling many epidemic diseases through effective surveillance. E-health implementation will result in improving the efficiency, better access of general public to the health care system, and eradication of diseases in Pakistan.

    Full Text Available Abstract Background Mortality from acute myocardial infarction (AMI is declining worldwide. We sought to determine if mortality in the Veterans Health Administration (VHA has also been declining. Methods We calculated 30-day mortality rates between 2004 and 2006 using data from the VHA External Peer Review Program (EPRP, which entails detailed abstraction of records of all patients with AMI. To compare trends within VHA with other systems of care, we estimated relative mortality rates between 2000 and 2005 for all males 65 years and older with a primary diagnosis of AMI using administrative data from the VHA Patient Treatment File and the Medicare Provider Analysis and Review (MedPAR files. Results Using EPRP data on 11,609 patients, we observed a statistically significant decline in adjusted 30-day mortality following AMI in VHA from 16.3% in 2004 to 13.9% in 2006, a relative decrease of 15% and a decrease in the odds of dying of 10% per year (p = .011. Similar declines were found for in-hospital and 90-day mortality. Based on administrative data on 27,494 VHA patients age 65 years and older and 789,400 Medicare patients, 30-day mortality following AMI declined from 16.0% during 2000-2001 to 15.7% during 2004-June 2005 in VHA and from 16.7% to 15.5% in private sector hospitals. After adjusting for patient characteristics and hospital effects, the overall relative odds of death were similar for VHA and Medicare (odds ratio 1.02, 95% C.I. 0.96-1.08. Conclusion Mortality following AMI within VHA has declined significantly since 2003 at a rate that parallels that in Medicare-funded hospitals.

    Impaired autonomic function is common in the acute poststroke phase but little is known about its effects on functional outcome after acute ischemic stroke. This study sought to investigate the impact of autonomic dysfunction by Ewing's classification on functional outcome 2 months after acute ischemic stroke. 34 consecutive acute ischemic stroke patients within 7 days after onset were enrolled. On admission, autonomic function was assessed by Ewing's battery tests. Stroke severity was assessed by the National Institutes of Health Stroke Scale (NIHSS), autonomy in activities of daily living by the Barthel Index (BI), and global disability by the modified Rankin Scale (mRS). BI and mRS were also evaluated 2 months after ischemic stroke onset. On admission, eight patients were diagnosed as minor autonomic dysfunction and 26 patients as relatively severe autonomic dysfunction. The prevalence of relatively severe autonomic dysfunction in ischemic stroke patients was 76.5%. There were no significant differences in baseline characteristics between the minor and severe autonomic dysfunction groups. 2 months after stroke onset, the mean BI score of patients with minor autonomic dysfunction and severe autonomic dysfunction increased from 76.3±15.3 on admission to 95.0±7.1, 66.5±15.2 on admission to 74.8±15.9 respectively. The mean BI score after 2-month stroke onset and the change in BI from admission to 2-month outcome (delta BI) in patients with severe autonomic dysfunction were lower than those in patients with minor autonomic dysfunction (all Pacute stroke patients. Relatively severe autonomic dysfunction is related to an unfavorable functional outcome in patients with acute ischemic stroke. Copyright © 2011 Elsevier B.V. All rights reserved.

    2016-11-01

    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.

    2016-03-01

    Full Text Available According to the World Health Organization there are almost two billion people worldwide who consume alcohol on a regular basis. It’s a common abuse and almost 80 million are diagnozed with “alcohol abuse disorders” (WHO 2002, 2004. Excessive alcohol consumption is related to more than 60 different medical conditions, as suicide, homicide and different forms of accidents. Some conditions are acute, while other conditions such as liver cirrhosis, chronic pancreatitis, haemorrhagic stroke and various forms of cancer, are chronic consequences. Non-carious destructions of teeth like dental erosion are also associated with frequent alcohol consumption, because of precipitation of salivary proline-rich proteins caused by polyphenols present in most alcoholic drinks. The high concentration of organic and inorganic acids and the habit of keeping the alcoholic drink in the mouth can cause chronic inflammations of the soft tissues in the mouth and can increase the negative side effects from metals of crowns, bridges, orthodontic devises and various restorations. A literature review has been made due to the authors clinical observations and experiences.

  17. Health effects of dietary phospholipids

    2012-01-01

    Full Text Available Abstract Beneficial effects of dietary phospholipids (PLs have been mentioned since the early 1900's in relation to different illnesses and symptoms, e.g. coronary heart disease, inflammation or cancer. This article gives a summary of the most common therapeutic uses of dietary PLs to provide an overview of their approved and proposed benefits; and to identify further investigational needs. From the majority of the studies it became evident that dietary PLs have a positive impact in several diseases, apparently without severe side effects. Furthermore, they were shown to reduce side effects of some drugs. Both effects can partially be explained by the fact that PL are highly effective in delivering their fatty acid (FA residues for incorporation into the membranes of cells involved in different diseases, e.g. immune or cancer cells. The altered membrane composition is assumed to have effects on the activity of membrane proteins (e.g. receptors by affecting the microstructure of membranes and, therefore, the characteristics of the cellular membrane, e.g. of lipid rafts, or by influencing the biosynthesis of FA derived lipid second messengers. However, since the FAs originally bound to the applied PLs are increased in the cellular membrane after their consumption or supplementation, the FA composition of the PL and thus the type of PL is crucial for its effect. Here, we have reviewed the effects of PL from soy, egg yolk, milk and marine sources. Most studies have been performed in vitro or in animals and only limited evidence is available for the benefit of PL supplementation in humans. More research is needed to understand the impact of PL supplementation and confirm its health benefits.

    The purpose of this study was to evaluate the acute effect of photobiomodulation therapy (PBM) on arterial pressure in hypertensive and normotensive rats with application in an abdominal region. Normotensive (2K) and hypertensive (2K-1C) wistar rats were treated with PBM. Systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP) and heart rate (HR) were measured before, during and after PBM application. The nitric oxide (NO) serum concentration was measured before and after PBM application. Vascular reactivity study was performed in isolated thoracic aortas. Aluminum gallium arsenide (GaAlAs) diode laser was used, at 660nm wavelength and 100mW optical output. The PBM application induced a decrease of SAP in 2K-1C rats. In 2K rats, the PBM application had no effect on SAP, DAP and MAP. Moreover, the magnitude of hypotensive effect was higher in 2K-1C than in 2K rats. The PBM application induced a decrease of HR in 2K-1C and 2K, with higher effect in 2K-1C rats. In 2K-1C, the hypotensive effect induced by PBM was longer than that obtained in 2K rats. PBM application induced an elevation of NO concentration in serum from 2K-1C and 2K rats, with higher effect in 2K-1C. In isolated aortic rings PBM effect is dependent of NO release, and is not dependent of nitric oxide synthase (NOS) activation. Our results indicate that the abdominal acute application of PBM at 660nm is able to induce a long lasting hypotensive effect in hypertensive rats and vasodilation by a NO dependent mechanism.

    Air pollution is a complex and ubiquitous mixture of pollutants including particulate matter, chemical substances and biological materials. There is growing awareness of the adverse effects on health of air pollution following both acute and chronic exposure, with a rapidly expanding body of evidence linking air pollution with an increased risk of respiratory (e.g., asthma, chronic obstructive pulmonary disease, lung cancer) and cardiovascular disease (e.g., myocardial infarction, heart failure, cerebrovascular accidents). Elderly subjects, pregnant women, infants and people with prior diseases appear especially susceptible to the deleterious effects of ambient air pollution. The main diseases associated with exposure to air pollutants will be summarized in this narrative review.

    This report introduces general information about diesel particles and their health effects. The purpose of this report is to introduce particulate matter pollution and present some recent studies made regarding the health effects of particulate matter. The aim is not to go very deeply into the science, but instead to keep the text understandable for the average layman. Particulate matter is a complex mixture of extremely small particles and liquid droplets. These small particles are made up of a number of components that include for example acids, such as nitrates and sulphates, as well as organic chemicals, metals and dust particles from the soil. Particulate matter comes from several sources, such as transportation emissions, industrial emissions, forest fires, cigarette smoke, volcanic ash and climate variations. Particles are divided into coarse particles with diameters less than 10 ..m, fine particles with diameters smaller than 2.5 ..m and ultra-fine particles with diameters less than 0.1 ..m. The particulate matter in diesel exhaust gas is a highly complex mixture of organic, inorganic, solid, volatile and partly volatile compounds. Many of these particles do not form until they reach the air. Many carcinogenic compounds have been found in diesel exhaust gas and it is considered carcinogenic to humans. Particulate matter can cause several health effects, such as premature death in persons with heart or lung disease, cancer, nonfatal heart attacks, irregular heartbeat, aggravated asthma, decreased lung function and an increase in respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing. It is estimated that in Finland about 1300 people die prematurely due to particles and the economic loss in the EU due to the health effects of particles can be calculated in the billions. Ultra-fine particles are considered to be the most harmful to human health. Ultrafine particles usually make the most of their quantity and surface area

    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.

    Environmental and occupational health effects associated with exposures to various chemicals are a subject of increasing concern. One recently developed methodology for assessing the health impacts of various chemical compounds involves the classification of similar chemicals into risk-assessment categories (RACs). This report reviews documented human health effects for a broad range of pollutants, classified by RACs. It complements other studies that have estimated human health effects by RAC based on analysis and extrapolation of data from animal research.

    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.

    Care transitions between settings are a well-known cause of medical errors. A key component of transition is information exchange, especially in long-term care (LTC). However, LTC is behind other settings in adoption of health information technologies (HIT). In this article, we provide some brief background information about care transitions in LTC and concerns related to technology. We describe a pilot project using HIT and secure messaging in LTC to facilitate electronic information exchange during care transitions. Five LTC facilities were included, all located within Oklahoma and serviced by the same regional health system. The study duration was 20 months. Both inpatient readmission and return emergency department (ED) visit rates were lower than baseline following implementation. We provide discussion of positive outcomes, lessons learned, and limitations. Finally, we offer implications for practice and research for implementation of HIT and information exchange across care settings that may contribute to reduction in readmission rates in acute care and ED settings.

    Side effects in the short term Recreational use of Ecstasy (3,4-methylenedioxymethamphetamine or MDMA), a synthetic drug, has considerably increased over the last decade. Since its appearance it is associated with the rave culture, but its use has spread to other social settings. The drug produces euphoria and empathy, but can lead to side effects, notably acute, potentially lethal, toxicity (malignant hyperthermia and/or hepatitis). Neurotoxicity in the long-term Moreover, MDMA has been shown to induce long-term deleterious effects and provoke neurotoxic affecting the serotoninergic system. However, the psychopathological consequences of such neurotoxicity are still controversial, particularly since many ecstasy consumers are multi-drug users. A complex pharmacological profile The mechanism of action of MDMA involves various neurobiological systems (serotonin, dopamine, noradrenalin), that may all interact.

    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.

    Ever since it was first used in armed conflict, mustard gas (sulfur mustard, MG) has been known to cause a wide range of acute and chronic injuries to exposure victims. The earliest descriptions of these injuries were published during and in the immediate aftermath of the First World War, and a further series of accounts followed the Second World War. More recently, MG has been deployed in warfare in the Middle East and this resulted in large numbers of victims, whose conditions have been studied in detail at hospitals in the region. In this review, we bring together the older and more recent clinical studies on MG toxicity and summarize what is now known about the acute and chronic effects of the agent on the eyes, skin, respiratory tract and other physiological systems. In the majority of patients, the most clinically serious long-term consequences of MG poisoning are on the respiratory system, but the effects on the skin and other systems also have a significant impact on quality of life. Aspects of the management of these patients are discussed.

    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.

    Objective:To observe the effects antiarrhythmic peptide 10 (AAP10) aon acute ventricular arrhythmia and the phosphorylation state of ischemic myocardium connexin.Methods:Acute total ischemia and partial ischemia models were established by ceasing perfusion and ligating the left anterior descending coronary artery in SD rats. The effects of AAP10 (1 mg/L) on the incidence rate of ischemia-induced ventricular arrhythmia were observed. The ischemic myocardium was sampled to detect total-Cx43 and NP-Cx43 by immunofluorescent staining and western blotting. the total-Cx43 expression was detected through image analysis system by semi-quantitative analysis.Results: AAP10 could significantly decrease the incidence of ischemia-induced ventricular tachycardia and ventricular fibrillation. During ischemic stage, total ischemia (TI) and AAP10 total ischemia (ATI) groups were compared with partial ischemia (PI) and AAP10 partial ischemia (API) groups. The rates of incidence for arrhythmia in the ATI and API groups (10% and 0%) were lower than those in the TI and PI groups (60% and 45%). The difference between the two groups was statistically significant (P=0.019, P=0.020). The semi-quantitative analysis results of the ischemic myocardium showed that the total-Cx43 protein expression distribution areas for TI, ATI, PI and API groups were significantly decreased compared with the control group. On the other hand, the NP-Cx43 distribution areas of TI, ATI, PI and API groups were significantly increased compared with the control group (P>0.05). AAP10 could increase the total-Cx43 expression in the ischemic area and decrease the NP-Cx43 expression. Western blot results were consistent with the results of immunofluorescence staining.Conclusions:AAP10 can significantly decrease the rate of incidence of acute ischemia-induced ventricular tachycardia and ventricular fibrillation. Acute ischemic ventricular arrhythmias may have a relationship with the decreased phosphorylation of Cx43

    Objective To evaluate the effects of acute glucose level changes on expression of prepro-orexin, orexin 1 receptor (OX1R) and orexin 2 receptor (OX2R) mRNA in rat hypothalamus tissue and pancreatic islets cells.Methods Thirty adult male Wistar rats were randomly divided into three equal groups (n= 10). The acute hypoglycemia rat model was induced by a single subcutaneous injection of insulin. Twenty acute hypoglycemia rats were divided into group B and group C. Group B was allowed to eat freely, while group C was food-deprived. Control rats were injected the same volume of saline. The effect of glucose levels (2.8 mmol/L and 8.3 mmol/L) on pancreatic islet cell orexin system was detected in pancreas islet cell cultured in vitro. The expression of prepro-orexin and OXR mRNA was examined in rat hypothalamus tissue and pancreatic islets cell cultured in vitro using reverse transcription-polymerase chain reaction (RTPCR).Results Expression of orexin mRNA increased about 150% for the food-deprived hypoglycemia rats in comparison with control group (P < 0.01), whereas expression of OX1R mRNA decreased up to 30% (P < 0.01). However, expression of OX2R mRNA was unchanged in comparison with control group. In vitro, after incubation with 2.8 mmol/L glucose for 6hours, the expression of prepro-orexin mRNA increased 2 times in rat pancreas islet cells in comparison with 8.3 mmol/Lglucose group (P < 0.01). But the expression of OX1R mRNA was not sensitive to acute glucose fluctuation.Conclusions Orexin in rat hypothalamus is stimulated by decline in blood glucose and inhibited by signals related to feeding. Moreover, glucose plays a role in modulating the gene expression of prepro-orexin in rat pancreatic islet cells.

    Previous research suggests that specific preconditioning activities such as whole-body vibration (WBV) and resistance training may play an important role in ensuing dynamic activities. The purpose of this study was to examine the effects of 2 preconditioning activities, WBV and power cleans (PC), on acute sprint performance. Two studies were conducted in which 14 (WBV) and 9 (PC) male track and field athletes were subjects. The WBV treatment consisted of 4 bouts of 5 seconds of high-knee running on a vibrating platform at 0, 30, 40, or 50 Hz. The PC treatment consisted of 3 PC reps at 90% 1RM. In both cases, acute sprint performance was the dependent variable of interest. For WBV, split times were recorded at 10, 20, and 40 m. Reaction times (RXN) as well as 5-, 10-, and 40-m split times were recorded for the PC study. Results indicated no significant differences between treatment and nontreatment groups for both studies. However, significant correlations were present between RXN and 5-m splits (r = 0.65) and RXN and 10-m splits (r = 0.63), although they decreased as a function of sprint distance to r = 0.43 at 40 m. These results suggest little efficacy for the use of WBV and PC as a means of augmenting acute sprint performance. However, a trend within the 30-Hz protocol may suggest that WBV as part of a warm-up for sprinting activities greater than 40 m (i.e., 100 m) could potentially result in a decreased sprint time of nearly 1/10th of a second, which is worth future consideration.

    Terpenes have a wide range of pharmacological properties, including antinociceptive action. The anti-inflammatory and antinociceptive effects of eucalyptol are well established. The purpose of this study was to evaluate the antinociceptive effect of eucalyptol on acute and neuropathic orofacial pain in rodent models. Acute orofacial and corneal nociception was induced with formalin, capsaicin, glutamate and hypertonic saline in mice. In another series, animals were pretreated with capsazepine or ruthenium red to evaluate the involvement of TRPV1 receptors in the effect of eucalyptol. In a separate experiment, perinasal tissue levels of IL-1β, TNF-α and IFN-γ were measured. Rats were pretreated with eucalyptol before induction of temporomandibular joint pain with formalin or mustard oil. In another experiment, rats were submitted to infraorbital nerve transection (IONX) to induce chronic pain, followed by induction of mechanical hypersensitivity using Von Frey hairs. Locomotor performance was evaluated with the open-field test, and molecular docking was conducted on the TRPV1 channel. Pretreatment with eucalyptol significantly reduced formalin-induced nociceptive behaviors in all mouse strains, but response was more homogenous in the Swiss strain. Eucalyptol produced antinociceptive effects in all tests. The effect was sensitive to capsazepine but not to ruthenium red. Moreover, eucalyptol significantly reduced IFN-γ levels. Matching the results of the experiment in vivo, the docking study indicated an interaction between eucalyptol and TRPV1. No locomotor activity changes were observed. Our study shows that eucalyptol may be a clinically relevant aid in the treatment of orofacial pain, possibly by acting as a TRPV1 channel antagonist.

    Nitrates are potent venous dilators and anti-ischemic agents. They are widely used for the relief of chest pain and pulmonary congestion in patients with acute coronary syndromes and heart failure. Nitrates, however, do not reduce mortality in patients with acute coronary syndromes. Combination of nitrates and hydralazine when given in addition to beta-blockers and angiotensin-converting enzyme (ACE) inhibitors reduce mortality and heart failure hospitalizations in patients with heart failure due to left ventricular systolic dysfunction who are of African-American origin. Side effects during nitrate therapy are common but are less well described in the literature compared with the reported side effects in patients with stable angina pectoris. The reported incidence of side effects varies highly among different studies and among various disease states. Headache is the most commonly reported side effect with an incidence of 12% in acute heart failure, 41-73% in chronic heart failure, 3-19% in unstable angina and 2-26% in acute myocardial infarction. The reported incidence of hypotension also differs: 5-10% in acute heart failure, 20% in chronic heart failure, 9% in unstable angina and < 1-48% in acute myocardial infarction, with the incidence being much higher with concomitant nitrate therapy plus angiotensin-converting enzyme inhibitors. Reported incidence of dizziness is as low as 1% in patients with acute myocardial infarction to as high as 29% in patients with heart failure. Severe headaches and/or symptomatic hypotension may necessitate discontinuation of nitrate therapy. Severe life threatening hypotension or even death may occur when nitrates are used in patients with acute inferior myocardial infarction associated with right ventricular dysfunction or infarction, or with concomitant use of phosphodiesterase-5 inhibitors or N-acetylcysteine. Despite the disturbing observational reports in the literature that continuous and prolonged use of nitrates may lead to

    Full Text Available The role of hyperbaric oxygen therapy (HBOT in the treatment of acute ischemic stroke is controversial. This prospective study assessed the efficacy and safety of HBOT as adjuvant treatment on 46 acute ischemic stroke in patients who did not receive thrombolytic therapy. The HBOT group (n=16 received conventional medical treatment with 10 sessions of adjunctive HBOT within 3–5 days after stroke onset, while the control group (n=30 received the same treatment but without HBOT. Early (around two weeks after onset and late (one month after onset outcomes (National Institutes of Health Stroke Scale, NIHSS scores and efficacy (changes of NIHSS scores of HBOT were evaluated. The baseline clinical characteristics were similar in both groups. Both early and late outcomes of the HBOT group showed significant difference (P≤0.001. In the control group, there was only significant difference in early outcome (P=0.004. For early efficacy, there was no difference when comparing changes of NIHSS scores between the two groups (P=0.140 but there was statistically significant difference when comparing changes of NIHSS scores at one month (P≤0.001. The HBOT used in this study may be effective for patients with acute ischemic stroke and is a safe and harmless adjunctive treatment.

    This article focuses on the redistributive effects of different measures to finance public health insurance. We analyse the implications of different financing options for public health insurance on the redistribution of income from good to bad health risks and from high-income to low-income individuals. The financing options considered are either income-related (namely income taxes, payroll taxes, and indirect taxes), health-related (co-insurance, deductibles, and no-claim), or neither (flat fee). We show that governments who treat access to health care as a basic right for everyone should consider redistributive effects when reforming health care financing.

    This study investigated the acute effect of static stretching methods (SS and proprioceptive neuromuscular facilitation (PNF on the static muscle strength (SMS. Eleven young male subjects with strength training experience, performed 3 tests with a 48h interval between them, randomly selected, where each one subject carried out all procedures: a hand grip without stretching; b hand grip preceded by static stretching of wrist flexors muscles; c hand grip preceded by PNF stretching of wrist flexors muscles. The Shapiro-Wilk test verified the normality of data, and a one-way ANOVA with repeated measures, followed by Tukey’s post hoc test, evaluated the differences between the groups. The significance was set at p 0.05. In conclusion, both stretching methods had caused negative effects on isometric strength, reducing its levels.

    Public health surveillance systems for acute hepatitis are limited: clinician reporting is insensitive and electronic laboratory reporting is nonspecific. Insurance claims and electronic health records are potential alternative sources. To compare the utility of laboratory data, diagnosis codes, and electronic health record combination data (current and prior viral hepatitis studies, liver function tests, and diagnosis codes) for acute hepatitis A and B surveillance. Retrospective chart review. Massachusetts ambulatory practice serving 350 000 patients per year. All patients seen between 1990 and 2008. Sensitivity and positive predictive value of immunoglobulin M (IgM), International Classification of Disease-Ninth Revision (ICD-9) diagnosis codes, and combination electronic health record data for acute hepatitis A and B. During the study period, there were 111 patients with positive hepatitis A IgMs, 154 with acute hepatitis A ICD-9 codes, and 77 with positive IgM and elevated liver function tests. On review, 79 cases were confirmed. Sensitivity and positive predictive value were 100% and 71% (95% confidence interval, 62%-79%) for IgM, 94% (92%-100%) and 48% (40%-56%) for ICD-9 codes and 97% (92%-100%) and 100% (96%-100%) for combination electronic health record data. There were 14 patients with positive hepatitis B core IgMs, 2564 with acute hepatitis B ICD-9 codes, and 125 with suggestive combinations of electronic health record data. Acute hepatitis B was confirmed in 122 patients. Sensitivity and positive predictive value were 9.4% (5.2%-16%) and 86% (60%-98%) for hepatitis B core IgM, 73% (65%-80%) and 3.6% (2.9%-4.4%) for ICD-9 codes, and 96% (91%-99%) and 98% (94%-99%) for electronic health record data. Laboratory surveillance using IgM tests overestimates the burden of acute hepatitis A and underestimates the burden of acute hepatitis B. Claims data are subject to many false positives. Electronic health record data are both sensitive and predictive

    Moderate consumption of red wine is associated with fewer cardiovascular events. We investigated whether red wine consumption counteracts the adverse vascular effects of cigarette smoking. Participants smoked 3 cigarettes alone or after drinking a titrated volume of red wine. Clinical chemistry, blood counts, plasma cytokine enzyme-linked immunosorbent assays, immunomagnetic separation of CD14(+) monocytes for gene expression analysis, fluorescence-activated cell sorting for microparticles, and isolation of circulating mononuclear cells to measure telomerase activity were performed, and urine cotinine levels were quantified. Compared with baseline, leukocytosis (P = .019), neutrophilia (P wine consumption. Cigarette smoke results in acute endothelial damage, vascular and systemic inflammation, and indicators of the cellular aging processes in otherwise healthy nonsmokers. Pretreatment with red wine was preventive. The findings underscore the magnitude of acute damage exerted by cigarette smoking in "occasional lifestyle smokers" and demonstrate the potential of red wine as a protective strategy to avert markers of vascular injury.

    2010-01-01

    Full Text Available Abstract Background Smoking and smoking cessation are considered to be associated with weight changes. We have recently shown that smoking acutely increases plasma levels of ghrelin, a known orexigenic hormone. Obestatin is a peptide encoded by the ghrelin gene, which opposes ghrelin effects on food intake. We conducted a study in adult volunteers measuring plasma levels of obestatin immediately after initiation of smoking. Methods 31 volunteers (mean age 32.2 ± 9.2 years and mean BMI 25.7 ± 4.1, 17 smokers and 14 non-smokers, were enrolled in our study. The 2 groups were matched in age and BMI. Plasma obestatin concentrations were determined at baseline (T0, 2 (T2, 5 (T5, 15 (T15, and 60 (T60 minutes after the initiation of smoking. Results In all 31 subjects, no significant difference in the mean values of plasma obestatin levels was observed from baseline at T2, T5, T15 and T60 after initiation of smoking (overall p = 0.15. However, a trend for higher obestatin levels was noted in smokers vs non-smokers (overall p = 0.069, which was not related to the pack-years. Conclusion On the contrary with ghrelin's response after smoking initiation, there is no such an acute response of plasma obestatin levels.

    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.

    AIM: To investigate the effect of exogenous erythropoietin (EPO) administration on acute lung injury (ALI) in an experimental model of sodium taurodeoxycholateinduced acute necrotizing pancreatitis (ANP).METHODS: Forty-seven male Wistar albino rats were randomly divided into 7 groups: sham group (n = 5),3 ANP groups (n = 7 each) and 3 EPO groups (n = 7each). ANP was induced by retrograde infusion of 5% sodium taurodeoxycholate into the common bile duct.Rats in EPO groups received 1000 U/kg intramuscular EPO immediately after induction of ANP. Rats in ANP groups were given 1 mL normal saline instead. All animals were sacrificed at postoperative 24 h, 48 h and 72 h. Serum amilase, IL-2, IL-6 and lung tissue malondialdehyde (MDA) were measured. Pleural effusion volume and lung/body weight (LW/BW) ratios were calculated. Tissue levels of TNF-α, IL-2 and IL-6 were screened immunohistochemically. Additionally, ox-LDL accumulation was assessed with immune-fluorescent staining. Histopathological alterations in the lungs were also scored.RESULTS: The mean pleural effusion volume, calculated LW/BW ratio, serum IL-6 and lung tissue MDA levels were significantly lower in EPO groups than in ANP groups. No statistically significant difference was observed in either serum or tissue values of IL-2 among the groups. The level of tumor necrosis factor-α (TNF-α)and IL-6 and accumulation of ox-LDL were evident in the lung tissues of ANP groups when compared to EPO groups, particularly at 72 h. Histopathological evaluation confirmed the improvement in lung injury parameters after exogenous EPO administration, particularly at 48 h and 72 h.CONCLUSION: EPO administration leads to a significant decrease in ALI parameters by inhibiting polymorphonuclear leukocyte (PMNL) accumulation,decreasing the levels of proinflammatory cytokines in circulation, preserving microvascular endothelial cell integrity and reducing oxidative stress-associated lipid peroxidation and therefore, can be

We searched for systematic reviews in 10 online databases, bibliographic references, and hand-searches in yoga-related journals. Included reviews satisfy Oxman criteria and specify yoga as a primary intervention in one or more randomized controlled trials for treatment in adults. The AMSTAR tool and GRADE approach evaluated the methodological quality of reviews and quality of evidence. Results. We identified 2202 titles, of which 41 full-text articles were assessed for eligibility and 26 systematic reviews satisfied inclusion criteria. Thirteen systematic reviews include quantitative data and six papers include meta-analysis. The quality of evidence is generally low. Sixteen different types of health conditions are included. Eleven reviews show tendency towards positive effects of yoga intervention, 15 reviews report unclear results, and no, reviews report adverse effects of yoga. Yoga appears most effective for reducing symptoms in anxiety, depression, and pain. Conclusion. Although the quality of systematic reviews is high, the quality of supporting evidence is low. Significant heterogeneity and variability in reporting interventions by type of yoga, settings, and population characteristics limit the generalizability of results.

Eleven reviews show tendency towards positive effects of yoga intervention, 15 reviews report unclear results, and no, reviews report adverse effects of yoga. Yoga appears most effective for reducing symptoms in anxiety, depression, and pain. Conclusion. Although the quality of systematic reviews is high, the quality of supporting evidence is low. Significant heterogeneity and variability in reporting interventions by type of yoga, settings, and population characteristics limit the generalizability of results.

    Context Little is known about how health insurance status affects decisions to seek care during emergency medical conditions like acute myocardial infarction (AMI). Objective To examine the association between lack of health insurance and financial concerns about accessing care among those with health insurance, and the time from symptom onset to hospital presentation (prehospital delays) during AMI. Design, Setting and Patients Multicenter, prospective registry of 3721 AMI patients enrolled between April, 2005 and December, 2008 from 24 U.S. hospitals. Health insurance status was categorized as uninsured, insured with financial concerns about accessing care, and insured without financial concerns. Insurance information was determined from medical records while financial concerns among those with health insurance were determined from structured interviews. Main Outcome Measure Prehospital delay times (≤2 hours, >2 to 6 hours, >6 hours), adjusted for demographic, clinical, social and psychological factors using hierarchical ordinal regression models. Results Of 3,721 patients, 738 (19.8%) were uninsured, and 689 (18.5%) were insured with financial concerns, and 2294 (61.7%) were insured without financial concerns. Uninsured and insured patients with financial concerns were more likely to delay seeking care during AMI, with prehospital delays >6 hours among 48.6% of uninsured patients, 44.6% of insured patients with financial concerns, and 39.3% of insured patients without financial concerns, as compared with prehospital delays of insured with financial concerns, and insured without financial concerns, respectively (P insurance with financial concerns and lack of insurance were associated with prehospital delays: insurance without financial concerns (reference); insurance with financial concerns, adjusted odds ratio [OR)], 1.21; 95% confidence interval [CI]: 1.05-1.41, P=.01; no insurance, adjusted OR 1.38, 95% CI: 1.17-1.63, P insurance and financial concerns

    The objective of this study was to identify the key enablers of change in re-orienting a remote acute care model to comprehensive primary healthcare delivery. The setting of the study was a 12-bed hospital in Fitzroy Crossing, Western Australia. Individual key informant, in-depth interviews were completed with five of six identified senior leaders involved in the development of the Fitzroy Valley Health Partnership. Interviews were recorded and transcripts were thematically analysed by two investigators for shared views about the enabling factors strengthening primary healthcare delivery in a remote region of Australia. Participants described theestablishment of a culturally relevant primary healthcare service, using a community-driven, 'bottom up' approach characterised by extensive community participation. The formal partnership across the government and community controlled health services was essential, both to enable change to occur and to provide sustainability in the longer term. A hierarchy of major themes emerged. These included community participation, community readiness and desire for self-determination; linkages in the form of a government community controlled health service partnership; leadership; adequate infrastructure; enhanced workforce supply; supportive policy; and primary healthcare funding. The strong united leadership shown by the community and the health service enabled barriers to be overcome and it maximised the opportunities provided by government policy changes. The concurrent alignment around a common vision enabled implementation of change. The key principle learnt from this study is the importance of community and health service relationships and local leadership around a shared vision for the re-orientation of community health services.

    AIM: To investigate the effects of rhubarb on severe acute pancreatitis (SAP) in rats.METHODS: Severe acute pancreatitis was induced by two intraperitoneal injections of cerulein (40 μg/kg body weight) plus 5-h restraint water-immersion stress. Rhubarb (75-150 mg/kg) was orally fed before the first cerulein injection.The degree of pancreatic edema, serum amylase level,local pancreatic blood flow (PBF), and histological alterations were investigated. The effects of rhubarb on pancreatic exocrine secretion in this model were evaluated by comparing with those of somatostatin.RESULTS: In the Cerulein+Stress group, severe edema and diffuse hemorrhage in the pancreas were observed,the pancreatic wet weight (11.60±0.61 g/Kg) and serum amylase (458 490±43 100 U/L) were markedly increased (P<0.01 vs control). In the rhubarb (150 mg/kg) treated rats, necrosis and polymorphonuclear neutrophil (PMN) infiltration in the pancreas were significantly reduced (P<0.01), and a marked decrease (50%) in serum amylase levels was also observed (P<0.01). PBF dropped to 38%(93±5 Ml/min per 100 g) of the control in the Cerulein+Stressgroup and partly recovered in the Cerulein+Stress+Rhubarb 150 mg group (135±12 Ml/min per 100 g) (P<0.01). The pancreatic exocrine function was impaired in the SAP rats.The amylase levels of pancreatic juice were reduced in the rats treated with rhubarb or somatostatin, comparing with that of untreated SAP group. The bicarbonate concentration of pancreatic juice was markedly elevated only in the rhubarb treated group (P<0.01).CONCLUSION: Rhubarb can exert protective effects on SAP, probably by inhibiting the inflammation of pancreas,improving pancreatic microcirculation, and altering exocrine secretion.

    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.

    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.

  18. Oxidant pollution - Effects on health

    Energy Technology Data Exchange (ETDEWEB)

    Bignon, J.

    Oxidizing pollution consists of air-borne gaseous, liquid and particle pollutants acting like reducing agents that can react with oxygen to produce toxic derivatives: superoxide anion, hydrogen peroxide, hydroxyl radicles and other free radicles. The major oxidizing gaseous pollutants are NO/sub x,/ particularly NO/sub 2/, ozone and photo-oxidizing agents as derivatives. Epidemiological studies have generally failed to show any significant relation between NO/sub 2/ concentration and respiratory disorders. Correlations are better with SO/sub 2/ and total suspended particles. In certain very sunny areas with high ozone levels, there is a link between O/sub 3/ concentration and respiratory disorders. Controlled trials comparing healthy and asthmatic volunteers have given variable results with highly raised bronchoreactivity at concentrations of 0.1 to 0.2 ppm NO/sub 2/ and 0.25 ppm O/sub 3/ for 1 to 2 hours in about half the studies. Using this data, the World Health Organisation (WHO) has established maximum exposure levels. Numerous investigations on exposure of animals to NO/sub 2/ and ozone have been performed using rodents, the dog, the cat and the primate. At concentrations close to peak urban air pollution levels various biochemical and cellular changes in the respiratory apparatus are generally observed. The areas most affected by NO/sub 2/ and ozone are the peripheral airways with distal stenosal bronchiolitis. NO/sub 2/ led to emphysematous lesions and O/sub 3/ to fibrosal hyperplasic lesions in alveolar tissue. Short bursts at high levels were generally more toxic than long exposure at low levels. There is an additive effect between NO/sub 2/ and ozone and with other pollutants. Exposure to nitrogen dioxide and ozone is conducive to bacterial and viral infection. Results for genitotoxicity and carcinogenic effects produced by NO/sub 2/ and ozone have hitherto been inconclusive.

    There is emerging evidence, although at early stages, of various detrimental health effects after smoking shisha. With regard to the cardiovascular system, there is a significant acute rise in cardiovascular markers, such as heart rate and blood pressure. The long-term effects on the cardiovascular system are yet to be established. Shisha smoking has also been significantly associated with lung cancer. Various other forms of cancer have also been documented, but have not reached statistical significance and require further research. Finally, shisha smoking increases the risk of infection and has been associated with outbreaks in the Middle East. Therefore, with the increasing consumption of shisha in Europe, especially in the UK, more research is required to tackle this potential public health threat.

    To determine the acute effects of a variety of recognized energy drinks on medical students, based on the hypothesis that these beverages may affect negatively cardiovascular parameters, stress levels and working memory. Eighty young healthy medical students were included in the study. 62.5 % of the participants were male, and the age mean was 21.45 years. Each person was evaluated via measurement of systolic and diastolic blood pressure, electrocardiogram (ECG), heart rate, oxygen saturation, breath rate, temperature, STAI score (to assess anxiety state), salivary cortisol and N-back task score (to determine cognitive enhancement). These evaluations were performed before and following the intake of either carbonated water or one of three energy drinks containing caffeine in similar concentrations and an undetermined energy blend; A contained less sugar and no taurine. Thirty-minute SBP increased significantly in the A and C groups. The B group exhibited a diminution of the percentage of the 1-h SBP increase, an increase of 1-h DBP and QTc shortening. HR showed an increase in the percent change in the A and C groups. Cortisol salivary levels increased in the B group. The STAI test score decreased in the C group. The percent change in N-back scores increased in the A group. The data reinforce the need for further research on the acute and chronic effects of energy drinks to determine the actual risks and benefits. Consumers need to be more informed about the safety of these energy drinks, especially the young student population.

    Municipality acute wards (MAWs) have recently been introduced in Norway. Their mandate is to provide treatment for patients who otherwise would have been hospitalized. Even though GPs are key stakeholders, little is known about how they perceive referring patients to these wards. The aim of this study was to investigate GPs' perspectives on factors relevant for their decision-making when referring patients to MAWs. We used a qualitative approach, conducting semi-structured interviews with 23 GPs from five different MAW catchment areas in the southeastern part of Norway. The data were analysed using thematic analysis. The GPs experienced challenges in deciding which patients were suitable for treatment at a MAW, including whether patients could be regarded as medically clarified, and whether these services were sufficient and safe. GPs were also under pressure from several other stakeholders when deciding where to refer their patients. Moreover, the MAWs were viewed not merely as an alternative to hospitals, but also as a service in addition to hospitals. This study improves our understanding of how GPs experience decentralized acute health care services, by identifying factors that influence and challenge their referral decisions. For these services to be used as intended in the collaboration reform, integrating the perspectives of GPs in the development and implementation of these services may be beneficial. © The Author 2016.

    The Taiwanese government subsidizes healthcare providers offering preventive medicine to patients to help reduce the threats of chronic sickness and halt skyrocketing medical expenditures. Usually, nurses are the primary workers who perform community health promotion; however, because of the chronic shortage of working nurses, many Taiwan hospitals have closed wards and deferred the responsibility of promoting primary prevention. With a community health promotion platform integrating interactive response features and Web sites for community patients and hospital staff, a case hospital efficiently sustained the community health services. The objective of this study was to assess the impact of the integrated community health promotion platform for conducting education. Fifty-four patients/residents were invited to join a quasi-experiment of health education, and a follow-up survey was conducted to assess the acceptance of the community health promotion platform from both the experimental group of learners/users and the hospital staff. The results showed that the community health promotion platform was effective in improving participant health awareness. The experimental group outperformed the control group, with higher posttest scores and longer knowledge retention. Furthermore, users indicated a high acceptance of the community health promotion platform.

    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.

  8. Efficacy of Acute Intermittent Hypoxia on Physical Function and Health Status in Humans with Spinal Cord Injury: A Brief Review

    2015-01-01

    Full Text Available Spinal cord injury (SCI results in a loss of motor and sensory function and is consequent with reductions in locomotion, leading to a relatively sedentary lifestyle which predisposes individuals to premature morbidity and mortality. Many exercise modalities have been employed to improve physical function and health status in SCI, yet they are typically expensive, require many trained clinicians to implement, and are thus relegated to specialized rehabilitation centers. These characteristics of traditional exercise-based rehabilitation in SCI make their application relatively impractical considering the time-intensive nature of these regimens and patients’ poor access to exercise. A promising approach to improve physical function in persons with SCI is exposure to acute intermittent hypoxia (IH in the form of a small amount of sessions of brief, repeated exposures to low oxygen gas mixtures interspersed with normoxic breathing. This review summarizes the clinical application of IH in humans with SCI, describes recommended dosing and potential side effects of IH, and reviews existing data concerning the efficacy of relatively brief exposures of IH to modify health and physical function. Potential mechanisms explaining the effects of IH are also discussed. Collectively, IH appears to be a safe, time-efficient, and robust approach to enhance physical function in chronic, incomplete SCI.

    Background Organophosphate poisoning is an important health problem in developing countries which causes death mainly by inducing acute lung injury.In this study,we examined the effects of penehyclidine hydrochloride (PHC),a selective M-receptor inhibitor,on dichlorvos-induced acute lung injury in swine.Methods Twenty-two female swines were randomly divided into control (n=5),dichlorvos (n=6),atropine (n=6),and PHC (n=5) groups.Hemodynamic data,extravascular lung water index (EVLWI),and pulmonary vascular permeability index (PVPI) were monitored; blood gas analysis and acetylcholinesterase (AchE) levels were measured.PaO2/FiO2,cardiac index (Cl),and pulmonary vascular resistance indices (PVRI) were calculated.At termination of the study,pulmonary tissue was collected for ATPase activity determination and wet to dry weight ratio (W/D) testing 6 hours post-poisoning.TUNEL assay,and Bax,Bcl-2,and caspase-3 expression were applied to pulmonary tissue,and histopathology was observed.Results After poisoning,PHC markedly decreased PVRI,increased CI more effectively than atropine.Anticholinergic treatment reduced W/D,apoptosis index (AI),and mitigated injury to the structure of lung; however,PHC reduced AI and caspase-3 expression and improved Bcl-2/Bax more effectively than atropine.Atropine and PHC improved ATPase activities; a significant difference between groups was observed in Ca2+-ATPase activity,but not Na+-K+-ATPase activity.Conclusions The PHC group showed mild impairment in pathology,less apoptotic cells,and little impact on cardiac function compared with the atropine group in dichlorvos-induced acute lung injury.

    There is a long history of certain medical conditions being associated with stigma, stereotypes, and negative attitudes. Research has shown that such attitudes can have a detrimental effect on patients presenting with stigmatised medical conditions and can even flow on to impact their family. The objective of this study was to measure the attitudes of undergraduate students enrolled in six different health-related courses at Monash University toward patients with intellectual disability, substance abuse, and acute mental illness. A convenience sample of undergraduate students enrolled in six health-related courses in first, second and third years at Monash University were surveyed. The Medical Condition Regard Scale--a valid and reliable, self-report measure of attitudes--was administered to students along with a brief demographic form. Mean scores, t-tests, and ANOVA were used to analyse student attitudes. Ethics approval was granted. 548 students participated. Statistically significant differences were found between the courses (p = 0.05), year of the course (p = 0.09), and gender (p = 0.04) for the medical condition of intellectual disability. There was no statistically significant difference between the courses, year of the course, gender, and age group for substance abuse or acute mental illness conditions. The findings suggest that students in undergraduate health-related courses, as a group, have a strong regard for patients with intellectual disability and some regard for patients with acute mental illness, but not for patients presenting with substance abuse problems.

    . Malaria is transmitted by the Anopheles mosquito and is highly prevalent in tropical and subtropical regions located between 40 degrees latitude North and 30 degrees latitude South. It causes acute attacks that leave the human body in such a poor state that health problems resulting from these attacks become chronic. Due to the high mortality and morbidity associated with it, malaria is considered the most serious of tropical diseases and a major public-health dilemma. Pregnant women are at high risk of becoming infected, as well as children in their first years of life. In pregnant women, malaria can cause anemia which can be the major cause of maternal mortality, especially during the first pregnancy. Malaria can also cause fetal anemia which frequently results in retarded intrauterine growth and low birth weight. Prophylactic treatment with antimalarial drugs during pregnancy is recommended in areas where the disease is endemic. The prophylactic treatment should focus primarily on primiparous women who are most susceptible. Chloroquine is safe and effective for antimalarial prophylaxis, and is not teratogenic. Proguanil is also safe for prophylactic use during pregnancy, particularly in areas where P. falciparum is resistant to chloroquine. Mefloquine may be used during the third trimester of pregnancy, only if other antimalarial drugs are unavailable or ineffective.

    2016-01-01

    With only a quarter of young people currently meeting physical activity guidelines, two key areas of concern are the effects of exercise on cardiometabolic health and cognition. Despite the fact that physical activity in young people is typically high intensity and intermittent in nature, much of the literature examines traditional endurance-type exercise. This review provides an update on the effects of high-intensity intermittent exercise on young people's cardiometabolic health and cognition. High-intensity intermittent exercise has acute beneficial effects on endothelial function and postprandial lipemia and chronic positive effects on weight management. In addition, there is emerging evidence regarding chronic benefits on the blood lipid profile, blood pressure, and proinflammatory and anti-inflammatory cytokines. Furthermore, emerging evidence suggests beneficial acute and chronic effects of high-intensity intermittent exercise on cognition. However, further research is required in both cardiometabolic health and cognition, particularly regarding the impact of school-based interventions in adolescents.

    This article reviews the health effects of the Chernobyl accident. The clearest effect to be seen to date is the dramatic increase in thyroid cancer in children. The evidence for increased leukaemia is less clear, but there are indications of increased leukaemia incidence in Russian clean-up workers. There is also evidence of increases in breast cancer, cataract and cardiovascular disease. However, to date the largest public health problem caused by the accident is the mental health impact.

    Some clinical trials have suggested that the inhaled long-acting β2-agonists (LABAs) may be effective in the treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Since indacaterol, the first once-daily LABA to be developed for the regular treatment of COPD, exhibits fast onset of action and 24-h duration of bronchodilation, we have investigated its effects in patients with AECOPD managed in the emergency department. In a randomised controlled pilot trial, we have enrolled 29 consecutive patients with a recent (i.e., within ≤ 4 d) history of AECOPD and requiring hospitalization. All patients received a standard protocol consisting of ipratropium bromide aerosol 500 μg three times a day, intravenous methylprednisolone 20 mg twice-daily and, if indicated, oral levofloxacin 500 mg once-daily. Moreover, they were randomly allocated to one of the two 5-day treatment groups (indacaterol maleate 300 μg once-daily or salbutamol nebulizer 1250 μg three times a day). The administration of indacaterol 300 μg to patients admitted to emergency department for an AECOPD resulted in a greater improvement of pulmonary function compared with traditional therapy, without cardiovascular side effects. Our results suggest that indacaterol could be a useful option in the treatment of AECOPD. However, further larger double-blinded randomized clinical trials are needed to validate the intriguing results obtained in this setting. Copyright © 2013 Elsevier Ltd. All rights reserved.

  19. The Impact of Private versus Social Health Insurance on Offered Waiting Times in German Acute Care Hospitals

    2009-01-01

    This paper shows that patients with private health insurance (PHI) are being offered significantly shorter waiting times than patients with statutory health insurance (SHI) in German acute hospital care. This behavior may be driven by the higher expected profitability of PHI relative to SHI holders. Further,we find that hospitals offering private insurees shorter waiting times as compared to SHI holders have a significantly better financial performance than those abstaining from or with less ...

    Exposure to acute stress alters cognition; however, few studies have examined the effects of acute stress on executive functions such as behavioral flexibility. The goal of the present experiments was to determine the effects of acute periods of stress on two distinct forms of behavioral flexibility: set-shifting and reversal learning. Male Sprague-Dawley rats were trained and tested in an operant-chamber-based task. Some of the rats were exposed to acute restraint stress (30 min) immediately before either the set-shifting test day or the reversal learning test day. Acute stress had no effect on set-shifting, but it significantly facilitated reversal learning, as assessed by both trials to criterion and total errors. In a second experiment, the roles of glucocorticoid (GR) and mineralocorticoid receptors (MR) in the acute-stress-induced facilitation of reversal learning were examined. Systemic administration of the GR-selective antagonist RU38486 (10 mg/kg) or the MR-selective antagonist spironolactone (50 mg/kg) 30 min prior to acute stress failed to block the facilitation on reversal learning. The present results demonstrate a dissociable effect of acute stress on set-shifting and reversal learning and suggest that the facilitation of reversal learning by acute stress may be mediated by factors other than corticosterone.

    Objective To highlight the current understanding of mixed phenotype acute leukemia (MPAL).Data sources We collected the relevant articles in PubMed (from 1985 to present),using the terms "mixed phenotype acute leukemia","hybrid acute leukemia","biphenotypic acute leukemia",and "mixed lineage leukemia".We also collected the relevant studies in WanFang Data base (from 2000 to present),using the terms "mixed phenotype acute leukemia" and "hybrid acute leukemia".Study selection We included all relevant studies concerning mixed phenotype acute leukemia in English and Chinese version,with no limitation of research design.The duplicated articles are excluded.Results MPAL is a rare subgroup of acute leukemia which expresses the myeloid and lymphoid markers simultaneously.The clinical manifestations of MPAL are similar to other acute leukemias.The World Health Organization classification and the European Group for Immunological classification of Leukaemias 1998 cdteria are most widely used.MPAL does not have a standard therapy regimen.Its treatment depends mostly on the patient's unique immunophenotypic and cytogenetic features,and also the experience of individual physician.The lack of effective treatment contributes to an undesirable prognosis.Conclusion Our understanding about MPAL is still limited.The diagnostic criteria have not been unified.The treatment of MPAL remains to be investigated.The prognostic factor is largely unclear yet.A better diagnostic cdteria and targeted therapeutics will improve the therapy effect and a subsequently better prognosis.

    If cost reductions produce a cost-quality trade-off, healthcare policy makers need to be more circumspect about the use of cost-effective initiatives. Additional empirical evidence about the relationship between cost and quality is needed to design a value-based payment system. We examined the association between cost and quality performances for acute myocardial infarction (AMI) care at the hospital level.In 2008, this cross-sectional study examined 69 hospitals with 6599 patients hospitalized under the Korea National Health Insurance (KNHI) program. We separately estimated hospital-specific effects on cost and quality using the fixed effect models adjusting for average patient risk. The analysis examined the association between the estimated hospital effects against the treatment cost and quality. All hospitals were distributed over the 4 cost × quality quadrants rather than concentrated in only the trade-off quadrants (i.e., above-average cost and above-average quality, below-average cost and below-average quality). We found no significant trade-off between cost and quality among hospitals providing AMI care in Korea.Our results further contribute to formulating a rationale for value-based hospital-level incentive programs by supporting the necessity of different approaches depending on the quality location of a hospital in these 4 quadrants.

    Effective and efficient acute pain management strategies have the potential to improve medical outcomes, enhance patient satisfaction, and reduce costs. Pain management records are having an increasing influence on patient choice of health care providers and will affect future financial reimbursement. Dedicated acute pain and regional anesthesia services are invaluable in improving acute pain management. In addition, nonpharmacologic and alternative therapies, as well as information technology, should be viewed as complimentary to traditional pharmacologic treatments commonly used in the management of acute pain. The use of innovative technologies to improve acute pain management may be worthwhile for health care institutions. Copyright © 2015 Elsevier Inc. All rights reserved.

    To investigate the acute effects of stochastic resonance whole body vibration (SR-WBV) training to identify possible explanations for preventive effects against musculoskeletal disorders. Twenty-three healthy, female students participated in this quasi-experimental pilot study. Acute physiological and psychological effects of SR-WBV training were examined using electromyography of descending trapezius (TD) muscle, heart rate variability (HRV), different skin parameters (temperature, redness and blood flow) and self-report questionnaires. All subjects conducted a sham SR-WBV training at a low intensity (2 Hz with noise level 0) and a verum SR-WBV training at a higher intensity (6 Hz with noise level 4). They were tested before, during and after the training. Conclusions were drawn on the basis of analysis of variance. Twenty-three healthy, female students participated in this study (age = 22.4 ± 2.1 years; body mass index = 21.6 ± 2.2 kg/m(2)). Muscular activity of the TD and energy expenditure rose during verum SR-WBV compared to baseline and sham SR-WBV (all P HRV were similar to those observed during sham SR-WBV. The same applies for most of the skin characteristics, while microcirculation of the skin of the middle back was higher during verum compared to sham SR-WBV (P changes over the three measurement points only in the middle back area (P = 0.022). There was a significant rise from baseline to verum SR-WBV (0.86 ± 0.25 perfusion units; P = 0.008). The self-reported chronic pain grade indicators of pain, stiffness, well-being, and muscle relaxation showed a mixed pattern across conditions. Muscle and joint stiffness (P = 0.018) and muscular relaxation did significantly change from baseline to different conditions of SR-WBV (P < 0.001). Moreover, muscle relaxation after verum SR-WBV was higher than after sham SR-WBV (P < 0.05). Verum SR-WBV stimulated musculoskeletal activity in young healthy individuals while cardiovascular activation was low. Training of

    AIM: To investigate the effect of Patrinia scabiosaefolia (PS) on the cholecystokinin (CCK) octapeptide- induced acute pancreatitis (AP) in rats.METHODS: Wistar rats weighing 240-260 g were divided into three groups: (1) Normal saline-treated group;(2) treatment with PS at 100 mg/kg group, in which PS was administered orally, followed by subcutaneous administration of 75 μg/kg CCK octapeptide three times after 1, 3 and 5 h, and this whole procedure was repeated for 5 d; (3) treatment with saline group,in which the protocols were the same as in treatment group with PS. We determined the pancreatic weight/body weight ratio, the levels of pancreatic HSP60,HSP72 and the secretion of pro-inflammatory cytokines.Repeated CCK octapeptide treatment resulted in the typical laboratory findings of experimentally induced pancreatitis.RESULTS: PS reduced the pancreatic weight/body weight ratio, the levels of serum amylase and lipase,and inhibited expressions of pro-inflammatory cytokines in the CCK octapeptide-induced AP. Furthermore, PS pretreatment increased the pancreatic levels of HSP60and HSP72.CONCLUSION: Pretreatment with PS has an antiinflammatory effect on CCK octapeptide-induced AP.

    Laing, A W; Galbraith, A

    1996-01-01

    Argues that the introduction of the quasi market mechanism into the Health Service has required that managers within NHS trusts acquire new managerial skills relating to market operations and, more importantly, reorientate their organizations towards the marketplace. Examines the pattern of development which has occurred within acute trusts across Scotland in the past three years, and argues that managers in the majority of trusts have developed a remarkably robust and relevant conceptualization of the nature and application of marketing within the NHS, reflecting the difficulties managers have faced in selling the concept of marketing to a generally sceptical body of clinicians. Notes, in part owing to such professional scepticism, that the development of marketing as an implementable approach to operations has lagged significantly behind the managerial conceptualization, although this cannot be attributed solely to resistance from clinicians and other health care professionals. Rather, suggests that such limited progress in implementing a market orientation reflects a range of "structural" barriers, both within individual trusts and the specific market environment faced by trusts.

    Objective This retrospective study aimed to explore the appropriate application and implications of Mental Health Act 2007 (NSW) (MHA) certificate use in a metropolitan generalist hospital in New South Wales. Methods A de-identified MHA certificate review was undertaken within acute generalist medical and surgical specialties between June 2012 and May 2013. To assess differences, data were separated into two categories according to whether certificates were completed by psychiatry trainees or generalist medical officers. Analysis of indications for detention was also undertaken and qualitatively matched against legislative criteria. Results A total of 43 MHA certificates were included in the review, which highlighted missing elements in most certificates. Differences were found when professional consensus by the researchers was used to match documentation to legislative criteria. The researchers disagreed with nine of the 16 indications (mental illness/mental disorder) by the generalist medical officers and only one indication by a psychiatry trainee. Six of the certificates appeared to be related to lack of capacity and need for treatment of medical conditions, thus more related to Guardianship Act 1987 (NSW) applications. Conclusion This study highlights inconsistencies in legislative knowledge and requirements between professional groups. Education and training opportunities have been identified to ensure greater consistency in application of the MHA, preservation of patient rights and avoidance of stigma. MHA use in this setting should be exercised with caution and by appropriately trained individuals. What is known about the topic? The MHA and its state and territory counterparts provide for the treatment, care and support of people who have a mental illness and the protection of a person's rights therein. Despite not being intended for application in generalist facilities, mental health legislation is widely used in generalist facilities and certificates are

    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.

    Objective:To investigate the effect of Chaiqinchengqi decoction (CQCQD) on serum amyloid A (SAA) in severe acute pancreatitis (SAP) patients. Methods: Thirty-five participants enrolled and were randomly assigned into either a treatment condition (n=17, treated with CQCQD) or a control condition (n=18, treated with placebo) 24 hours following the onset of the disease. No statistical difference was observed in either group at baseline. Upon admission, the Acute Physiology and Chronic Health Evaluation scoreⅡ (APACHEⅡ), SAA, serum C-reactive protein (CRP) and interleukin-6 (IL-6) were measured, as well as on the first, 3rd and 7th day and were compared between the two groups. Organ complications, infection, operation rate, mortality and hospital stay were also compared. Results:The duration of acute respiratory distress syndrome, acute hepatitis, acute renal failure, gastrointestinal failure and blood coagulation dysfunction were shorter in the treatment group than in those in the control group (P<0.05). The secondary infection rates and the hospital fees in the treatment group were lower than those in the control group (P< 0.05) as well as length of hospital stay (P< 0.01). After 3 days of hospitalization, the APACHEⅡ, score SAA levels, serum CRP and IL-6 in the treatment group was lower than those in the control group (P< 0.05). SAA was positively correlated with serum CRP (R= 0.346, P=0.042), Ranson score (R= 0.442, P= 0.008) and serum IL-6 (R=0.359, P=0.034). The area under the receiver operating characteristic curve of admission SAA predict pancreatic necrosis (PN) was 0.815 (95%CI:0.625-0.954;P=0.006). The best cut-off value of admission SAA was 7.85 mg/L with the sensitivity 84.6%and specificity 68.2%. Conclusions: The CQCQD can reduce the duration of organ damage through lowering the SAA in SAP patients and the SAA can early predict the PN and severity of SAP patients.

    Full Text Available Carbon monoxide poisoning (COP is one of the most common causes of mortality and morbidity due to poisoning in all over the world. Although the incidence of COP has not been known exactly in the childhood, almost one-third of CO exposures occurred in children. The data regarding COP in children are inconclusive. Children may be more vulnerable to CO exposure than adults as a result of their high respiration and metabolic rates, high oxygen metabolism, and immature central nervous system. Recent researches proposed new theories about neurological effects of CO toxicity. The clinical presentations associated acute COP may be various and nonspecific. Unrecognized CO exposure may lead to significant morbidity and mortality. CO exposed children often become symptomatic earlier, and recover more rapidly, than similarly CO exposed adults. Mild clinical signs and symptoms associated with COP are headache, dizziness, weakness, lethargy, and myalgia; however, severe signs and symptoms such as blurred vision, syncope, convulsion, coma, cardiopulmonary arrest and death can also accompany with COP. Neurologic manifestations can include altered mental status at different degrees, neck stiffness, tremor, ataxia, and positive Babinski's sign. Delayed neurologic sequels (DNS of COP might be seen in children like adults. DNS symptoms and signs in children include memory problems, mental retardation, mutism, fecal and urinary incontinence, motor deficits, facial palsy, psychosis, chronic headache, seizures, and epilepsy. After CO exposure children must be cared to detect and treat DNS. Although hyperbaric oxygen therapy (HBOT is reported to prevent development of DNS, its indications, application duration and procedures are controversial in both of the children and adults. Although their predictive values are limited, exposing to CO more than eight hours and suffering from CO-induced coma, cardiac arrest, lactic acidosis, high COHb levels, and pathologic findings

    The present study was carried out to characterize the effects of in vitro exposure to paving asphalt fume condensate (AFC) on alveolar macrophage (AM) functions and to monitor acute pulmonary responses to in vivo AFC exposure in rats. Methods: For in vitro studies, rat primary AM cultures were incubated with various concentrations of AFC for 24 h at 37 C. AM-conditioned medium was collected and assayed for lactate dehydrogenase (LDH) as a marker of cytotoxicity. Tumor necrosis factor-{alpha} (TNF-{alpha}) and interleukin-1 (IL-1) production were assayed in AM-conditioned medium to monitor AM function. The effect of AFC on chemiluminescence (CL) generated by resting AM or AM in response to zymosan or PMA stimulation was also determined as a marker of AM activity. For in vivo studies, rats received either (1) a single intratracheal (IT) instillation of saline, or 0.1 mg or 0.5 mg AFC and were killed 1 or 3 days later; or (2) IT instillation of saline, or 0.1, 0.5, or 2 mg AFC for three consecutive days and were killed the following day. Differential counts of cells harvested by bronchoalveolar lavage were measured to monitor inflammation. Acellular LDH and protein content in the first lavage fluid were measured to monitor damage. CL generation, TNF-{alpha} and IL-1 production by AM were assayed to monitor AM function. Results: In vitro AFC exposure at <200 {mu}g/ml did not induce cytotoxicity, oxidant generation, or IL-1 production by AM, but it did cause a small but significant increase in TNF-{alpha} release from AM. In vitro exposure of AM to AFC resulted in a significant decline of CL in response to zymosan or PMA stimulation. The in vivo studies showed that AFC exposure did not induce significant neutrophil infiltration or alter LDH or protein content in acellular lavage samples. Macrophages obtained from AFC-exposed rats did not show significant differences in oxidant production or cytokine secretion at rest or in response to LPS in comparison with control

  18. Health and environmental effects document for batteries: 1980

    Energy Technology Data Exchange (ETDEWEB)

    1980-11-01

    An evaluation is presented of the ecological and health effects of the near-term electric storage batteries (lead/acid, nickel/zinc, and nickel/iron) as related to electric and hybrid vehicle applications. The storage battery technology is considered in its totality, and emissions are estimated for the complete cycle. For estimating quantities of various emissions, the market penetration is assumed to be 3 x 10/sup 6/ Pb/acid battery-powered vehicles and 8 x 10/sup 6/ each of the Ni/Zn and Ni/Fe battery-powered vehicles on the road by the year 2000. Ecological effects are assessed using the Estimated Permissible Concentration (EPC) approach. Pb, S, Cu, Ni, Cd, Zn, and Sb appear to be the most hazardous emission constituents and exceed EPC values for protection of ecology in one or more of the battery-related industries. More definitive, quantitative estimates of damage to the biota and to the ecosystem are not feasible because of paucity of relevant information. Health effects as a result of increased levels of lead, arsenic, and cadmium in the environment and risks of exposure to arsine, stibine, and antimony trioxide released during charging are assessed. Health effects among the occupationally exposed are also assessed using the toxicological models. Acute and chronic effects of exposure to stibine, arsine, and antimony trioxide are described.

    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&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&N) HT to the scored acute health effects. We performed a simulation study to calculate the induced peak 10 g spatial-averaged SAR (psSAR10g) in the brains of 16 selected H&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 psSAR10g 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.

Objectives: i To analyse the symptoms, signs and diagnosis of Acute Respiratory Infections in under-fives. ii To compare the experience with WHO guidelines. Design: Retrospective analysis of under-five patients admitted with ARI. Setting: Comprehensive Rural Health Services Project Hospital, Ballabgarh. Participants; Under-fives admitted with ARI. Outcome: Signs, symptoms, diagnosis of ARI. Statistical Analysis: Descriptive analysis of findings. Results: 73.6% admitted were males, 63.2% were infants. The most commonly complained symptoms at the time of admission were fever (69.6%, Cough (63.2%, breathlessness (61.6% inability to feed (19.2 and diarrhoea (19.2%. 76.0% had crepitations, 26.4% had chest in drawing, 23.2% had ronchi, and 14.4%had respiratory distress. Only 33.3% had respiratory rate more than 60 per minute among children less than 2 months old, 56.9% had respiratory rate more than 50 per minute among children 2-12 month old. 54.3% had respiratory rate more than 40 per minute among 12 months to 5 years of age. 76% had pneumonias. The case fatality rate (CFR was 12.8% and most of the deaths occurred within 24 hours of arrival. The C.F.R was more in females and among young infants. Conclusion: Fever should be included in the lead symptoms of ARI along with cough and breathlessness. There is a need for looking at Respiratory rate for recognition of Pneumonias.

    Objective To determine the occurrence of neurological changes during the first 48 hours after acute stroke as it relates to the initial stroke severity assessment. Methods The assessment with the National Institutes of Health Stroke Scale (NIHSS) was performed serially for the first 48 hours on 68 consecutive ischemic stroke patients admitted to the Department of Geriatric Cardiology at the Khanh Hoa Hospital, Nha Trang, Vietnam. Incidence of stroke progression (a ≥ 3-point increase on the NIHSS) was recorded and analysis performed to determine its association with initial stroke severity and other demographic and physiological variables. Deficit resolution by 48 hours, defined as an NIHSS score of 0 or 1, measured the frequency of functional recovery predicted by the initial deficit.Results Overall progression was noted in 28% of events (19/68). Applying Bayes' solution to the observed frequency of worsening, the greatest likelihood of predicting future patient progression occurred with NIHSS score of =7 and >7. Patients with an initial NIHSS score of =7 experienced a 13% (6/47) worsening rate versus those of an initial score of>7 with a 62% (13/21) worsening rate (P<0.01). 42.5%(20/47) of those with an initial score of =7 were functionally normal at 48 hours, whereas only 4.7% (1/21) of those with scores of >7 retnrned to a normal examination within this period (x2, P<0.05). Conclusions This study suggests that the early clinical course of neurological deficit after acute stroke be dependent on the initial stroke severity and that a dichotomy in early outcome exist surrounding an initial NIHSS score of 7. These findings may have significant implications for the design and patient stratification in treatment protocols with respect to primary clinical outcome.

    Little is known about the acute precipitants of ischemic stroke, although evidence suggests infections contribute to risk. We hypothesized that acute hospitalization for infection is associated with the short-term risk of stroke. The case-crossover design was used to compare hospitalization for infection during case periods (90, 30, or 14 days before an incident ischemic stroke) and control periods (equivalent time periods exactly 1 or 2 years before stroke) in the Cardiovascular Health Study, a population-based cohort of 5888 elderly participants from 4 US sites. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated by conditional logistic regression. Confirmatory analyses assessed hazard ratios of stroke from Cox regression models, with hospitalization for infection as a time-varying exposure. During a median follow-up of 12.2 years, 669 incident ischemic strokes were observed in participants without a baseline history of stroke. Hospitalization for infection was more likely during case than control time periods; for 90 days before stroke, OR=3.4 (95% CI, 1.8 to 6.5). The point estimates of risks were higher when we examined shorter intervals: for 30 days, OR=7.3 (95% CI, 1.9 to 40.9), and for 14 days, OR=8.0 (95% CI, 1.7 to 77.3). In survival analyses, risk of stroke was associated with hospitalization for infection in the preceding 90 days, adjusted hazard ratio=2.4 (95% CI, 1.6 to 3.4). Hospitalization for infection is associated with a short-term increased risk of stroke, with higher risks observed for shorter intervals preceding stroke.

    Communication failures between physicians and nurses are one of the most common causes of adverse events for hospitalized patients, as well as a major root cause of all sentinel events. Communication technology (ie, the electronic medical record, computerized provider order entry, email, and pagers), which is a component of health information technology (HIT), may help reduce some communication failures but increase others because of an inadequate understanding of how communication technology is used. Increasing use of health information and communication technologies is likely to affect communication between nurses and physicians. The purpose of this study is to describe, in detail, how health information and communication technologies facilitate or hinder communication between nurses and physicians with the ultimate goal of identifying how we can optimize the use of these technologies to support effective communication. Effective communication is the process of developing shared understanding between communicators by establishing, testing, and maintaining relationships. Our theoretical model, based in communication and sociology theories, describes how health information and communication technologies affect communication through communication practices (ie, use of rich media; the location and availability of computers) and work relationships (ie, hierarchies and team stability). Therefore we seek to (1) identify the range of health information and communication technologies used in a national sample of medical-surgical acute care units, (2) describe communication practices and work relationships that may be influenced by health information and communication technologies in these same settings, and (3) explore how differences in health information and communication technologies, communication practices, and work relationships between physicians and nurses influence communication. This 4-year study uses a sequential mixed-methods design, beginning with a

    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.

    Recent research has started to identify mood disorders and problems associated with acute and chronic wounds, which have been shown to contribute to delayed healing, poor patient well-being and a reduced quality of life. Furthermore, mood disorders have been shown to have a negative impact on financial costs for service providers and the wider society in terms of treatment and sickness absence. This study aimed to survey a multinational sample of health professionals to explore their perspective and awareness of mood disorders amongst acute and chronic wound patients. Responses were received from n = 908 health professionals working in Asia, Africa, Australia, Europe, North America and South America. A strong awareness of the prevalence of mood disorders appeared to be widespread among the health professionals across the world, in addition to a view on the potential factors contributing to these problems with mood. Despite this, it was thought that few patients were actually receiving treatment for their mood disorders. Implications for clinical practice include the need for health professionals to engage actively with their patients to enable them to learn from their experiences. Studies that explore the benefits of treatments and techniques appropriate for minimising mood disorders in patients with wounds would provide empirical evidence for health professionals to make recommendations for patients with acute and chronic wounds. © 2013 The Authors.

    Mental health nurses work with acutely unwell patients, and the busy setting is characterised by unpredictable events. This paper is a report of a review conducted to identify, analyse and synthesize research in adult acute inpatient mental health units, which focused on nurse-patient interaction. Several electronic databases were searched using relevant keywords to identify studies published from 1999-present. Qualitative studies published in English were included if they specifically investigated nurse-patient interaction in acute inpatient care in adult settings. Eighteen studies were included (23 papers). Findings were grouped into the following six categories: 1) sophisticated communication; 2) subtle discriminations; 3) managing security parameters; 4) ordinary communication; 5) reliance on colleagues; and 6) personal characteristics. These studies of acute inpatient mental health units reveal that nurse communication involves interpersonal approaches and modalities that exemplify highly developed communication and personal skills designed specifically for this challenging setting. Further quality research should focus on the conditions that enable the development of therapeutic interactional skills and the relationship of these skills to the nuanced context in which they are practiced.

    2012-05-01

    Unfavourable effects on the respiratory and the cardiovascular systems from short-term and long-term inhalation of air pollution are well documented. Exposure to freshly generated mixed combustion emissions such as those observed in proximity to roadways with high volumes of traffic and those from ice-resurfacing equipment are of particular concern. This is because there is a greater toxicity from freshly generated whole exhaust than from its component parts. The particles released from emissions are considered to cause oxidative damage and inflammation in the airways and the vascular system, and may be related to decreased exercise performance. However, few studies have examined this aspect. Several papers describe deleterious effects on health from chronic and acute air pollution exposure. However, there has been no research into the effects of long-term exposure to air pollution on athletic performance and a paucity of studies that describe the effects of acute exposure on exercise performance. The current knowledge of exercising in the high-pollution environment and the consequences that it may have on athlete performance are reviewed.

This is also the way how to improve the efficiency of health care. The term of efficiency in relation to the health services. In economics, the efficiency is the ratio between the achieved result (effect) and the expenditure of a specified amount of resources. Mathematically, this ratio is expressed as follows: efficiency = end-result/costs Linked to the Health care, the efficiency may be understood also differently from its economic term.(ABSTRACT TRUNCATED AT 400 WORDS)

    Although traditional meditation has been found to be effective in improving physical and mental health of subjects, there was a paucity of research of the effect of active or dynamic meditation on these variables. Therefore, the present study was aimed at studying the effect of dynamic meditation on mental health of the subjects. Total sample of the present study comprised 60 subjects, 30 each in experimental and control group. Subjects in experimental group were given 21-day training in dynamic meditation. Mental health of the experimental and control group subjects was measured in pre- and post-condition with the help of Mental Health Inventory developed by Jagadish and Srivastava (Mental Health inventory, Manovaigyanik Parikshan Sansthan, Varanasi, 1983). Obtained data were analyzed with the help of ANCOVA. In post-condition, experimental group scored better than control group on integration of personality, autonomy and environmental mastery. Effect sizes of dynamic meditation on these dimensions of mental health were large. However, experimental group and control group did not differ significantly on positive self-evaluation, perception of reality and group-oriented attitude dimensions of mental health in post-condition. Overall, dynamic meditation training was effective in improving mental health of the subjects.

  14. Protective Effects of Hydrogen Gas on Experimental Acute Pancreatitis.

    Directory of Open Access Journals (Sweden)

    Hao-Xin Zhou

    Full Text Available Acute pancreatitis (AP is an inflammatory disease mediated by damage to acinar cells and pancreatic inflammation. In patients with AP, subsequent systemic inflammatory responses and multiple organs dysfunction commonly occur. Interactions between cytokines and oxidative stress greatly contribute to the amplification of uncontrolled inflammatory responses. Molecular hydrogen (H2 is a potent free radical scavenger that not only ameliorates oxidative stress but also lowers cytokine levels. The aim of the present study was to investigate the protective effects of H2 gas on AP both in vitro and in vivo. For the in vitro assessment, AR42J cells were treated with cerulein and then incubated in H2-rich or normal medium for 24 h, and for the in vivo experiment, AP was induced through a retrograde infusion of 5% sodium taurocholate into the pancreatobiliary duct (0.1 mL/100 g body weight. Wistar rats were treated with inhaled air or 2% H2 gas and sacrificed 12 h following the induction of pancreatitis. Specimens were collected and processed to measure the amylase and lipase activity levels; the myeloperoxidase activity and production levels; the cytokine mRNA expression levels; the 8-hydroxydeoxyguanosine, malondialdehyde, and glutathione levels; and the cell survival rate. Histological examinations and immunohistochemical analyses were then conducted. The results revealed significant reductions in inflammation and oxidative stress both in vitro and in vivo. Furthermore, the beneficial effects of H2 gas were associated with reductions in AR42J cell and pancreatic tissue damage. In conclusion, our results suggest that H2 gas is capable of ameliorating damage to the pancreas and AR42J cells and that H2 exerts protective effects both in vitro and in vivo on subjects with AP. Thus, the results obtained indicate that this gas may represent a novel therapy agent in the management of AP.

  18. An overview of health effects on noise

    Science.gov (United States)

    Osada, Y.

    1988-12-01

    Although noise can damage the inner ear and cause other pathological changes, its most common negative effects are non-somatic, such as a perception of noisiness and disturbance of daily activities. According to the definition of health by WHO, this should be considered as a health hazard. These health effects of noise can be classified into the following three categories: (I) hearing loss, perception of noisiness and masking are produced along the auditory pathway and are thus direct and specific effects of noise; (II) interference with performance, rest and sleep, a feeling of discomfort and some physiological effects are produced as indirect and non-specific effects via reticular formation of the midbrain; (III) annoyance is not merely a feeling of unpleasantness but the feeling of being bothered or troubled, and includes the development of a particular attitude toward the noise source. Individual or group behavioral responses will be evoked when annoyance develops. Annoyance and behavioral response are integrated and composite effects. The health effects of noise are modified by many factors related to both the noise and the individual. Noise level, frequency spectrum, duration and impulsiveness modify the effects. Sex, age, health status and mental character also have an influence on the effects. Direct effects of noise are most dependent on the physical nature of the noise and least dependent on human factors. Indirect effects are more dependent, and integrated effects most dependent, on human factors.

    This study investigates the effects of lysine-induced acute renal failure. Female dogs received a lysine hydrochloride (lysine) of 4500 mg/kg/day (3.75 ml/kg/hr) for 3 consecutive days. The dogs were observed for clinical signs. Body weights were recorded, food consumption and water consumption calculated, and urinalysis and blood biochemistry were performed daily. Plasma samples for amino acid determinations were obtained from all dogs, which were necropsied on Day 3. Histopathological examinations were done on all test animals. Compound-related findings include the following. Blood biochemistry results showed increases in ammonia, blood urea nitrogen, blood urea nitrogen/creatinine ratio, and creatinine. Urinary changes consisted of increases in urine volume, total protein, albumin, gamma-glutamyl transpeptidase, and N-acetyl-beta-D-glucosaminidase. In addition, macroscopic findings consisted of pale, congested capsule; microscopic findings consisted of hypertrophy of proximal convoluted tubule (mainly S1 segment), and degeneration/desquamation of urinary tubule (mainly S3 segment with hyaline casts) in the kidney. From these findings, it can be concluded that lysine is nephrotoxic in dogs. Nephrotoxicity of lysine may relate to direct tubular toxicity and to tubular obstruction.

    The aim of this study was to verify the acute effects of the application of local vibration on upper limbs during resistance training on the number of maximum repetitions, metabolic and hormonal responses. 32 volunteers performed a maximum voluntary contraction test during a lat pulldown exercise. After the test, all volunteers underwent one conventional resistance training session and one resistance training session with local vibration. In both interventions, volunteers performed 4 sets with the highest possible number of repetitions of the lat pulldown exercise at 55% of maximum voluntary contraction. During the vibratory resistance training intervention, vibration was locally applied (20-Hz and 12-mm). During the conventional resistance training, volunteers performed the same procedures without vibration. Blood samples were taken at each experimental session before and 5 min after the end of each intervention. No significant differences were observed in number of maximum repetitions between the series of vibratory and conventional training. Serum testosterone, cortisol and lactate were significantly increased after 2 interventions. Vibratory resistance training induced greater increases in testosterone and lactate concentrations. No significant changes were found in creatine kinase, creatinine or urea concentration. These data indicate that local vibration increases the metabolic and anabolic response to the resistance training, without changing the training volume. © Georg Thieme Verlag KG Stuttgart · New York.

    In this study, acute effects of cigarette smoking on the pattern electroretinogram (PERG) were investigated. First, variability of the PERG was studied in a group of young male smokers (26 right eyes of 26 subjects). Then PERGs were investigated in a group of habitual smokers (17 right eyes of 17 subjects) in separate real smoking and sham smoking sessions. On each session PERGs were recorded pre-smoking (PS), immediately after smoking (IAS) and 5 min after smoking (5th) conditions. Real smoking significantly increased P50 amplitudes and decreased N95 latencies. Regarding P50 amplitudes in the real smoking sessions, the differences were significant between PS and IAS (PS: 3.3 +/- 0.5 muV, IAS: 3.7 +/- 0.7microV, P = 0.015) and between PS-5th (PS: 3.3 +/- 0.5microV, 5th: 4.1 +/- 0.9microV, P = 0.039). There was significant difference (P = 0.024) between N95 latencies of PS (98.5 +/- 6.9 ms) and IAS (94.7 +/- 5.1 ms) in the real smoking sessions. No statistically significant difference was observed in sham smoking sessions. Our results indicated, for the first time, that cigarette smoking may influence PERG amplitude and latency significantly in habitual smokers.

    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

    Acute coronary syndrome is one of the most frequent medical emergencies in developing countries. To determine, from the perspective of the Colombian health system, the cost-effectiveness of ticagrelor compared to clopidogrel for the treatment of patients with acute coronary syndrome. We conducted a cost-effectiveness analysis from the perspective of the Colombian health system comparing ticagrelor and clopidogrel for the treatment of patients with acute coronary syndrome. To estimate the expected costs and outcomes, a Markov model was constructed in which patients could remain stable without experiencing new cardiovascular events, suffer from a new event, or die. For the baseline case, a 10-year time horizon and a discount ratio of 3% for costs and benefits were adopted. The transition probabilities were extracted from the PLATO (Platelet Inhibition and Patient Outcomes) clinical trial. Vital statistics were drawn from the Departmento Administrativo Nacional de Estadística (DANE) and additional information from Colombian patients included in the Access registry. To identify and measure resource use, a standard case was built by consulting guidelines and protocols. Unit costs were obtained from Colombian rate lists. A probabilistic sensitivity analysis was conducted in which costs were represented by a triangular distribution, and the effectiveness through a beta distribution. In the base case, the additional cost per quality-adjusted life-year gained with ticagrelor was COP$ 28,411,503. The results were sensitive to changes in the time horizon and the unit cost of clopidogrel. For a willingness-to-pay equivalent to three times the Colombian per capita gross domestic product, the probability of ticagrelor being cost-effective was 75%. Ticagrelor is a cost-effective strategy for the treatment of patients with acute coronary syndrome in Colombia.

    Background For patients recovering from severe acute illness, admission to a long-term acute care hospital (LTAC) is an increasingly common alternative to continued management in an intensive care unit. Objective To examine the effectiveness of LTAC transfer in patients with chronic critical illness. Research Design Retrospective cohort study in United States hospitals from 2002 to 2006. Subjects Medicare beneficiaries with chronic critical illness, defined as mechanical ventilation and at least 14 days of intensive care. Measures Survival, costs and hospital readmissions. We used multivariate analyses and instrumental variables to account for differences in patient characteristics, the timing of LTAC transfer and selection bias. Results A total of 234,799 patients met our definition of chronic critical illness. Of these, 48,416 (20.6%) were transferred to an LTAC. In the instrumental variable analysis, patients transferred to an LTAC experienced similar survival compared to patients who remained in an intensive care unit (adjusted hazard ratio = 0.99, 95% CI: 0.96 to 1.01, p=0.27). Total hospital-related costs in the 180 days following admission were lower among patients transferred to LTACs (adjusted cost difference = -$13,422, 95% CI: -26,662 to -223, p=0.046). This difference was attributable to a reduction in skilled nursing facility admissions (adjusted admission rate difference = -0.591 (95% CI: -0.728 to -0.454, p <0.001). Total Medicare payments were higher (adjusted cost difference = $15,592, 95% CI: 6,343 to 24,842, p=0.001). Conclusions Patients with chronic critical illness transferred to LTACs experience similar survival compared with patients who remain in intensive care units, incur fewer health care costs driven by a reduction in post-acute care utilization, but invoke higher overall Medicare payments.

    Background 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. Purpose and Setting 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. Method 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. Participants 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. Result 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 t52 = 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. PMID:21589696

    Limited data exist as to the relative contribution of sex and gender on health-related quality of life (HRQL) among patients with acute coronary syndrome (ACS). This study aims to evaluate the effect of sex and gender-related variables on long-term HRQL among young adults with ACS. GENESIS-PRAXY (GENdEr and Sex determInantS of cardiovascular disease: from bench to beyond-Premature Acute Coronary SYndrome) is a multicenter, prospective cohort study (January 2009 to August 2013) of adults aged 18 to 55 years, hospitalized with ACS. HRQL was measured at baseline, 1, 6, and 12 months using the Short Form-12 and Seattle Angina Questionnaire (SAQ) among 1213 patients. Median age was 49 years. Women reported worse HRQL than men over time post-ACS, both in terms of physical and mental functioning. Gender-related factors were more likely to be predictors of HRQL than sex. Femininity score, social support, and housework responsibility were the most common gender-related predictors of HRQL at 12 months. We observed an interaction between female sex and social support (β=0.44 [95% confidence interval, 0.01, 0.88]; P=0.047) for the physical limitation subscale of the SAQ. Young women with ACS report significantly poorer HRQL than young men. Gender appears to be more important than sex in predicting long-term HRQL post-ACS. Specific gender-related factors, such as social support, may be amenable to interventions and could improve the HRQL of patients with premature ACS. © 2014 The Authors.

    2016-01-01

    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.

    This paper aims to assess administrative and clinical manager stances on health system reform. Understanding these stances will help to identify cultural differences and competing agendas between these two key health service stakeholders and contribute to developing strategies to improve organisational performance. A qualitative methodology was used comprising in-depth open-ended interviews conducted in 2007 with 26 administrative and clinical managers who managed clinical units. This paper provides empirical insights into the ways that administrative and clinical mangers conceive of their managerial roles in relation to health care reform and performance improvement in health services. The findings suggest that developing a hybrid clinical manager culture as a means to bridge the gap between administrative and clinical manager stances on reform objectives, while possible, is not yet being realised. The research has relevance for health services that are experiencing organisational transformation. However, its location in one health service limits the generalisability of findings to other sites. Further research is needed to assess the opportunities for a hybrid culture to emerge as well as its effect. While attention is predominantly directed to clinician groups as a key stakeholder in implementing health reform policies, this paper has implications for how administrative managers also structure their roles and responsibilities to create an organisational climate conducive to change. This will include strategies to support clinical managers to make the transition from a predominantly clinical, to a clinical managerial, orientation. This paper addresses a significant problem in health service governance, namely the divide between the value stances of dual hierarchies. This problem is only now gaining prominence as a significant barrier to health reform.

    Full Text Available Biomass fuels, charcoal and kerosene are the most used cooking fuels in Tanzania. Biomass fuel use has been linked to Acute Respiratory Infections (ARI in children. It is not clear whether the use of charcoal and kerosene has health advantage over biomass fuels. In this study, the effects of biomass fuels, charcoal/kerosene on ARI in children under five years old in Tanzania are quantified and compared based on data from Tanzania Demographic and Health survey conducted between 2004 and 2005. Approximately 85% and 15% of children were from biomass fuels and charcoal/kerosene using homes respectively. Average ARI prevalence was about 11%. The prevalence of ARI across various fuel types used for cooking did not vary much from the national prevalence. Odds ratio for ARI, adjusting for child’s sex, age and place of residence; mother’s education, mother’s age at child birth and household living standard, indicated that the effect of biomass fuels on ARI is the same as the effect of charcoal/kerosene (OR 1.01; 95% CI: 0.78-1.42. The findings suggest that to achieve meaningful reduction of ARI prevalence in Tanzania, a shift from the use of biomass fuels, charcoal and kerosene for cooking to clean fuels such as gas and electricity may be essential. Further studies, however, are needed for concrete policy recommendation.

    The management of acute respiratory distress syndrome (ARDS) was investigated with the use of heliox in an experimental model. To investigate whether heliox can be considered a new therapeutic approach in ARDS. ARDS was designed in Wistar albino male rats, 250-300 g in weight, by intratracheal instillation of physiological saline solution. Anesthezied and tracheotomized rats with ARDS were pressure-controlled ventilated. At the end of 210 min, helium gas was tried. All rats were assigned to two groups: Group 1 (n = 10) was the control group, and was given no treatment; group 2 (n = 7) was given heliox (He: O(2) = 50:50). The heliox group received heliox for 1 h continously. Rats were continued to be kept on a ventilator through the experiment. Two hours after the last inhalation, both lungs of the rats were excised for both histopathological examination and immunohistochemical evaluation. Histopathological grading were expressed as median interquartile range. Mann-Whitney U-test was used to assess the relationships between the variables. The infiltation of neutrophils were decreased in rats treated with heliox. Edema in the interstitial and intraalveolar areas was less than that of the control rats. Also, the diminishing of perivascular and/or intraalveolar hemorrhage was apperant. Hyaline membrane (HM) formation decreased in the heliox group compared with the control group. Decreased inducible nitric oxide synthase expression was shown via immunohistochemical examination in the heliox group. The present study histopathologically indicated the effectiveness of heliox in the decreasing of neutrophil infiltation, interstitial/intraalveolar edema, perivascular and/or intraalveolar hemorrhage and HM formation in ARDS. Besides the known effect of heliox in obstructive lung disease, inhaled heliox therapy could be associated with the improvement of inflamation in ARDS.

    Orthostatic tolerance is impaired following an acute bout of exercise. This study examined the effect of fluid ingestion following treadmill exercise in restoring the cardiovascular responses to an orthostatic stress. Five men (age, 29.6 +/- 3.4 yrs) were exposed to a graded lower body negative (LBNP) pressure protocol (0 to -50 mmHg) during euhydration without exercise (C), 20 minutes after exercise dehydration (D), 20 minutes after exercise and fluid ingestion (FI20), and 60 minutes after exercise and fluid ingestion (FI60). Fluid ingestion (mean +/- SE) consisted of water-ingestion equivalent to 50% of the body weight lost during exercise (520 +/- 15 ml). Exercise dehydration resulted in significantly higher heart rates (119 +/- 8 vs 82 +/- 7 bpm), lower systolic blood pressures (95 +/- 1.7 vs 108 +/- 2.3 mmHg), a smaller increase in leg circumference (3.7 +/- 4 vs 6.9 +/- 1.0 mm), and an attenuated increase in total peripheral resistance (2.58 +/- 1.2 vs 4.28 +/- 0.9 mmHg/L/min) at -50 mmHg LBNP compared to the C condition. Fluid ingestion (both 20 and 60), partially restored the heart rate, systolic blood pressure, and total peripheral resistance responses to LBNP, but did not influence the change in leg circumference during LBNP (4 +/- 0.3 for R20 and 2.8 +/- 0.4 mm for R60). These data illustrate the effectiveness of fluid ingestion on improving orthostatic responses following exercise, and suggest that dehydration is a contributing factor to orthostatic intolerance following exercise.

    Vegetarian diets are those diets mainly based on the consumption of vegetable product, but that also permit consumption of eggs and milk. The American Dietetic Association made a declaration on these vegetarian diets in which they stated that vegetarian diet is healthy, nutritionally adequate and provides health benefits in the prevention and treatment of certain diseases>. Some studies have shown beneficial results in obesity, cancer, Parkinson disease, hypertension, type 2 diabetes mellitus and urinary stones, compared with the omnivorous. The possible theoretical benefits in some diseases has been seen in the medical practice (diabetes mellitus, obesity, cardiovascular risk). However more studies are needed in the case of Parkinson's disease and rheumatoid arthritis.

    Case Report has presented health effects of high level of irradiation with gamma rays from {sup 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)

    Full Text Available Abstract Background Cannabis intoxication is related to a number of physical and mental health risks with ensuing social costs. However, little attention has been given to the investigation of possible pharmacological interactions in this condition. Objective To review the available scientific literature concerning pharmacological interventions for the treatment of the acute effects of cannabis. Methods A search was performed on the Pubmed, Lilacs, and Scielo online databases by combining the terms cannabis, intoxication, psychosis, anxiety, and treatment. The articles selected from this search had their reference lists checked for additional publications related to the topic of the review. Results The reviewed articles consisted of case reports and controlled clinical trials and are presented according to interventions targeting the physiological, psychiatric, and cognitive symptoms provoked by cannabis. The pharmacological interventions reported in these studies include: beta-blockers, antiarrhythmic agents, antagonists of CB-1 and GABA-benzodiazepine receptors, antipsychotics, and cannabidiol. Conclusion Although scarce, the evidence on pharmacological interventions for the management of cannabis intoxication suggests that propanolol and rimonabant are the most effective compounds currently available to treat the physiological and subjective effects of the drug. Further studies are necessary to establish the real effectiveness of these two medications, as well as the effectiveness of other candidate compounds to counteract the effects of cannabis intoxication, such as cannabidiol and flumazenil.

    The mental health consequences of war and other forms of organized violence for children represent a serious global public health issue. Much of the research on the mental health of war-affected civilians has focused on refugees who have sought asylum in high-income countries and face the dual stress of a traumatic past and resettlement. This review will focus on the mental health of refugee children who have fled war as well as interventions to both prevent and treat adverse mental health outcomes. While war can have devastating mental health consequences, children raised in the midst of armed conflict also display resilience. Effective interventions for refugee children will be discussed both in terms of prevention and treatment of psychopathology, with a focus on recent developments in the field.

This study was performed to elucidate the effect of timereleased garlic powder tablets (Allicor in prevention of ARD in children. At the first stage, in open-labeled 5-months study it has been shown that ARD morbidity was reduced by 2.4-fold in 172 Allicor-treated (600 mg daily schoolchildren aged 7-16 as compared to 468 controls. At the second stage, the effects of Allicor (300 mg daily on ARD morbidity were investigated in the double-blinded placebo-controlled randomized 5-months comparative study in 42 children aged 10-12 in comparison with 41 placebo-treated children and 73 benzimidazole-treated children. Allicor treatment reduced ARD morbidity by 2.4-fold as compared to placebo, and by 1.7-fold as compared to benzimidazole. Health index in Allicor-treated group was 1.5-fold higher as compared either to placebo- or benzimidazole-treated children. The results of this study have demonstrated that garlic powder tablets Allicor are effective in non-specific prevention of acute respiratory infections in children and possess no side effects. Additionally, the commonly used ARD prevention withbenzimidazole turned to be entirely ineffective in placebocontrolled study, so the development of new useful and safe efficient drugs like garlic-based preparations is of ultimate importance.

    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.

    Identification of patients with acute ischaemic stroke who could most benefit from arterial recanalization after endovascular treatment remains an unsettled issue. Although several classifications of collateral circulation have been proposed, the clinical role of collaterals is still debated. We evaluated the effect of the collateral circulation in relation to recanalization as a predictor of clinical outcome. Data were prospectively collected from 103 patients consecutively treated for proximal middle cerebral or internal carotid artery occlusion. The collateral circulation was evaluated with a novel semiquantitative-qualitative score, the Careggi collateral score (CCS), in six grades. Both CCS and recanalization grades (TICI) were analysed in relation to clinical outcome. A statistical analysis was performed to evaluate the effect of interaction between recanalization and collateral circulation on clinical outcome. Out of the 103 patients, 37 (36.3%) had poor collaterals, and 65 (63.7%) had good collaterals. Patients with good collaterals had lower basal National Institute of Health Stroke Scale (NIHSS), more distal occlusion, smaller lesions at 24h CT scan and better functional outcome. After multivariate analysis, the interaction between recanalization and collateral grades was significantly stronger as a predictor of good outcome (OR 6.87, 95% CI 2.11-22.31) or death (OR 4.66, 95%CI 1.48-14.73) compared to the effect of the single variables. Collaterals showed an effect of interaction with the recanalization grade in determining a favourable clinical outcome. Assessment of the collateral circulation might help predict clinical results after recanalization in patients undergoing endovascular treatment for acute ischaemic stroke.

    The latest recommendations for building dynamic health behavior theories emphasize that cognitions, emotions, and behaviors--and the nature of their inter-relationships--can change over time. This paper describes the development and psychometric validation of four scales created to measure smoking-related causal attributions, perceived illness severity, event-related emotions, and intention to quit smoking among patients experiencing acute cardiac symptoms. After completing qualitative work with a sample of 50 cardiac patients, we administered the scales to 300 patients presenting to the emergency department for cardiac-related symptoms. Factor analyses, alpha coefficients, ANOVAs, and Pearson correlation coefficients were used to establish the scales' reliability and validity. Factor analyses revealed a stable factor structures for each of the four constructs. The scales were internally consistent, with the majority having an alpha of >0.80 (range: 0.57-0.89). Mean differences in ratings of the perceived illness severity and event-related emotions were noted across the three time anchors. Significant increases in intention to quit at the time of enrollment, compared to retrospective ratings of intention to quit before the event, provide preliminary support for the sensitivity of this measure to the motivating impact of the event. Finally, smoking-related causal attributions, perceived illness severity, and event-related emotions correlated in the expected directions with intention to quit smoking, providing preliminary support for construct validity.

    This article shares findings of work undertaken with a group of mental health ward managers to consider their roles through workshops using an action learning approach. The tensions between the need to balance the burden of administrative tasks and act as clinical role models, leaders and managers are considered in the context of providing recovery-focused services. The group reviewed their leadership styles, broke down the administrative elements of their roles using activity logs, reviewed their working environments and considered how recovery focused they believed their wards to be. Findings support the notion that the ward manager role in acute inpatient settings is at times unmanageable. Administration is one aspect of the role for which ward managers feel unprepared and the high number of administrative tasks take them away from front line clinical care, leading to frustration. Absence from clinical areas reduces opportunities for role modeling good clinical practice to other staff. Despite the frustrations of administrative tasks, overall the managers thought they were supportive to their staff and that their wards were recovery focused.

    Full Text Available Abstract Background Most studies on Health-related Quality of Life (HRQOL in children with cancer were conducted in developed countries. The aims of this study were to assess the HRQOL in childhood acute lymphoblastic leukemia (ALL patients in Indonesia and to assess the influence of demographic and medical characteristics on HRQOL. Methods After cultural linguistic validation, a cross-sectional study of HRQOL was conducted with childhood ALL patients and their guardians in various phases of treatment using the Pediatric Quality of Life Inventory™ (PedsQL™ 4.0 Generic Core Scale and the Pediatric Quality of Life Inventory™ (PedsQL™ 3.0 Cancer Module. Results Ninety-eight guardians and 55 patients participated. The internal consistency of both scales ranged from 0.57 to 0.92. HRQOL of Indonesian patients was comparable with those in developed countries. There were moderate to good correlations between self-reports and proxy-reports, however guardians tended to report worse HRQOL than patients. Children of the 2–5 year-group significantly had more problems in procedural anxiety, treatment anxiety and communication subscales than in older groups (p Conclusion Younger children had more problems in procedural anxiety, treatment anxiety and communication subscales. Therefore, special care during intervention procedures is needed to promote their normal development. Psychosocial support should be provided to children and their parents to facilitate their coping with disease and its treatment.

  12. Health effects of vegan diets.

    Science.gov (United States)

    Craig, Winston J

    2009-05-01

    Recently, vegetarian diets have experienced an increase in popularity. A vegetarian diet is associated with many health benefits because of its higher content of fiber, folic acid, vitamins C and E, potassium, magnesium, and many phytochemicals and a fat content that is more unsaturated. Compared with other vegetarian diets, vegan diets tend to contain less saturated fat and cholesterol and more dietary fiber. Vegans tend to be thinner, have lower serum cholesterol, and lower blood pressure, reducing their risk of heart disease. However, eliminating all animal products from the diet increases the risk of certain nutritional deficiencies. Micronutrients of special concern for the vegan include vitamins B-12 and D, calcium, and long-chain n-3 (omega-3) fatty acids. Unless vegans regularly consume foods that are fortified with these nutrients, appropriate supplements should be consumed. In some cases, iron and zinc status of vegans may also be of concern because of the limited bioavailability of these minerals.

    Full Text Available 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.

    Exercise with flexible poles provides fast eccentric and concentric muscle contractions. Although the literature reports significant muscle chain activity during this exercise, it is not clear if a single bout of exercise induces cardiac changes. In this study we assessed the acute effects of flexible pole exercise on cardiac autonomic regulation. The study was performed on 22 women between 18 and 26 years old. We assessed heart rate variability (HRV) in the time (SDNN, RMSSD and pNN50) and frequency (HF, LF and LF/HF ratio) domains and geometric indices of HRV (RRTri, TINN, SD1, SD2 and SD1/SD2 ratio). The subjects remained at rest for 10 min and then performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 60 min and HRV was analyzed. We observed no significant changes in time domain (SDNN: p=0.72; RMSSD: p=0.94 and pNN50: p=0.92) or frequency domain indices (LF [nu]: p=0.98; LF [ms(2)]: p=0.72; HF [nu]: p=0.98; HF [ms(2)]: p=0.82 and LF/HF ratio: p=0.7) or in geometric indices (RRTri: p=0.54; TINN: p=0.77; SD1: p=0.94; SD2: p=0.67 and SD/SD2: p=0.42) before and after a single bout of flexible pole exercise. A single bout of flexible pole exercise did not induce significant changes in cardiac autonomic regulation in healthy women. Copyright © 2014 Sociedade Portuguesa de Cardiologia.

    Background Atrial electrical remodeling (AER) contributes to the maintainance of atrial fibrillation (AF). This study was to compare the effects of Losartan with those of Diltiazem on tachycardia-induced acute AER in rabbits.Methods Twenty-one rabbits paced with maximal atrial capture rate for 3 hours in the right atrium (RA) were randomly divided into saline group, Diltiazem group and Losartan group. After autonomic blockage, we measured atrial effective refractory period (AERP), AERP rate adapting feature, AERP dispersion and RA conduction time at basic cycle lengths (BCLs) of 200 ms and 150 ms at baseline, 0.5 hour, 1 hour, 2 and 3 hours after rapid atrial pacing. Results In the saline group, there was a prompt decrease in AERP as a result of rapid atrial pacing, and AERP200 and AERP150 were shortened sharply within 0.5 hour of pacing (30.2±10.5 ms and 24.1±9.1 ms, respectively). The AERP did not change dramatically in the Diltiazem and Losartan groups. In the saline group, the value of (AERP200-AERP150)/50 ms in high RA was 0.17±0.08 at baseline and became significantly smaller at 0.5 hour (0.08±0.06), 1 hour (0.09±0.06), 2 hours (0.08±0.04) and 3 hours (0.09±0.05) (all P<0.05), suggesting a reduction of rate adaptation of AERP. The value of (AERP200-AERP150)/50 ms in high RA did not change during the 3 hours of pacing in both Diltiazem and Losartan groups. In the saline group, AERP dispersion increased significantly at 2 and 3 hours (P<0.05). However, Diltiazem could not prevent the increase of AERP dispersion at 3 hours (P<0.05). During Losartan infusion, the AERP dispersion was no longer increased after rapid atrial pacing. There was no significant difference in RA conduction time among the three groups.Conclusion Like calcium antagonist Diltiazem, Losartan could prevent AERP shortening and preserve rate adaptation of AERP after rapid atrial pacing. Losartan is more effective than Diltiazem in inhibiting the increase of AERP dispersion.

    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)

    Full Text Available In order to improve current clinical treatment of human hypocortisolism, it is necessary to understand molecular aspects of this pathophysiology. In this study liver tissues from male Wistar rats were used as an experimental model to study structural and functional properties of glucocorticoid receptor (GR in the absence of glucocorticoid hormones (GC. Results show that acute adrenalectomy (ADX significantly increases the number of GR binding sites and GR protein content. In addition, acute ADX stimulates increase in stability of the GR, decrease in stability of the glucocorticoid- receptor complex (G-R, and changes in accumulation of the G-R complex in nuclei and its cellular distribution. .

    Health systems in low- and middle-income countries were designed to provide episodic care for acute conditions. However, the burden of disease has shifted to be overwhelmingly dominated by chronic conditions and illnesses that require health systems to function in an integrated manner across a spectrum of disease stages from prevention to palliation. Low- and middle-income countries are also aiming to ensure health care access for all through universal health coverage. This article proposes a framework of effective universal health coverage intended to meet the challenge of chronic illnesses. It outlines strategies to strengthen health systems through a "diagonal approach." We argue that the core challenge to health systems is chronicity of illness that requires ongoing and long-term health care. The example of breast cancer within the broader context of health system reform in Mexico is presented to illustrate effective universal health coverage along the chronic disease continuum and across health systems functions. The article concludes with recommendations to strengthen health systems in order to achieve effective universal health coverage.

    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.

    Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi...... method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis......, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment. Our results showed that none of the protocols addressed all 14...

    Recent epidemiological studies have demonstrated associations between air pollution and adverse effects that extend beyond respiratory and cardiovascular disease, including low birth weight, appendicitis, stroke, and neurological/neurobehavioural outcomes (e.g., neurodegenerative disease, cognitive decline, depression, and suicide). To gain insight into mechanisms underlying such effects, we mapped gene profiles in the lungs, heart, liver, kidney, spleen, cerebral hemisphere, and pituitary of male Fischer-344 rats immediately and 24h after a 4-h exposure by inhalation to particulate matter (0, 5, and 50mg/m(3) EHC-93 urban particles) and ozone (0, 0.4, and 0.8 ppm). Pollutant exposure provoked differential expression of genes involved in a number of pathways, including antioxidant response, xenobiotic metabolism, inflammatory signalling, and endothelial dysfunction. The mRNA profiles, while exhibiting some interorgan and pollutant-specific differences, were remarkably similar across organs for a set of genes, including increased expression of redox/glucocorticoid-sensitive genes and decreased expression of inflammatory genes, suggesting a possible hormonal effect. Pollutant exposure increased plasma levels of adrenocorticotropic hormone and the glucocorticoid corticosterone, confirming activation of the hypothalamic-pituitary-adrenal axis, and there was a corresponding increase in markers of glucocorticoid activity. Although effects were transient and presumably represent an adaptive response to acute exposure in these healthy animals, chronic activation and inappropriate regulation of the hypothalamic-pituitary-adrenal axis are associated with adverse neurobehavioral, metabolic, immune, developmental, and cardiovascular effects. The experimental data are consistent with epidemiological associations of air pollutants with extrapulmonary health outcomes and suggest a mechanism through which such health effects may be induced.

    Acetaminophen (APAP) overdose causes acute liver injury or even death in both humans and experimental animals. We investigated the effect of sesame oil on APAP-induced acute liver injury. Male Wistar rats were given APAP (1,000 mg/kg; orally) to induce acute liver injury. Acetaminophen significantly increased aspartate transaminase, alanine transaminase, lipid peroxidation, and superoxide anion and hydroxyl radical generation levels; it also induced glutathione depletion. Sesame oil (8 mL/kg; orally) did not alter the gastric absorption of APAP, but it inhibited all the parameters altered by APAP and protected the rats against APAP-induced acute liver injury. We hypothesize that sesame oil maintained the intracellular glutathione levels, reduced reactive oxygen species levels, and inhibited lipid peroxidation in rats with APAP-induced acute liver injury.

    Genetic polymorphisms influence the metabolism of ethanol and methanol, but the potential effects of genetic predisposition on the clinical course, outcome and short-term health sequelae of acute methanol poisoning are unknown. To evaluate the role of the MEOS system in methanol poisoning, we analysed the effect of three polymorphisms (RsaI - rs2031920; PstI - rs3813867; insertion/deletion I/D) within the CYP2E1 enzyme (MEOS system) in 50 adult survivors of methanol poisoning and compared their genotype frequencies with 460 controls. The minor allele frequencies of all three polymorphisms were below 5% in both groups. We did not detect significant differences in the genotype frequencies between survivors of methanol poisoning and controls (p = 0.34 for the RsaI variant; p = 0.59 for the PstI variant and p = 0.21 for the I/D polymorphism). The carriers of at least one minor allele in the CYP2E1 gene had less severe clinical symptoms and better short-term outcome after acute poisoning. Variants within the CYP2E1 gene are likely not significant genetic determinants of acute methanol poisoning (if survivors are analysed), but they may influence the severity of methanol poisoning and its visual/central nervous system (CNS) outcome.

    Full Text Available Context: This review describes the health effects of beryllium exposure in the workplace and the environment. Aim: To collate information on the consequences of occupational and environmental exposure to beryllium on physiological function and well being. Materials and Methods: The criteria used in the current review for selecting articles were adopted from proposed criteria in The International Classification of Functioning, Disability, and Health. Articles were classified based on acute and chronic exposure and toxicity of beryllium. Results: The proportions of utilized and nonutilized articles were tabulated. Years 2001-10 gave the greatest match (45.9% for methodological parameters, followed by 27.71% for 1991-2000. Years 1971-80 and 1981-90 were not significantly different in the information published and available whereas years 1951-1960 showed a lack of suitable articles. Some articles were published in sources unobtainable through requests at the British Library, and some had no impact factor and were excluded. Conclusion: Beryllium has some useful but undoubtedly harmful effects on health and well-being. Measures need to be taken to prevent hazardous exposure to this element, making its biological monitoring in the workplace essential.

    Full Text Available Background: acute dentoalveolar abscess is a dental emergency and one of the major condition affecting the population; however, there are few studies on the subject. Objective: to describe the clinical and epidemiological characteristics of acute dentoalveolar abscess in patients of the health area VII in Cienfuegos. Methods: a descriptive study was conducted from January to December 2013 in the Health Area VII, Cienfuegos. The universe consisted of 672 patients and the sample included 374 individuals selected by simple random sampling. Primary data recording and data collection was obtained from medical records prior informed consent of the patients. The main variables were age, sex, pulp irritating agents. Results: females were more affected with 55, 35% and the 19-34 year age group with 33.69%. The main pulp irritator was microbial, 59.36%. Among the iatrogenic factors, the remains of decayed tissues were significant with 32.35%. Conclusions: there is a high number of patients with acute dentoalveolar abscess, thus, as a dental emergency, the dentist should know the characteristics and factors that develop the disease to promote a comprehensive job in terms of health promotion, prevention, treatment and rehabilitation of affected patients.

    Information on health-seeking behavior and utilization of health facilities in slums of Addis Ababa is scarce, impeding the implementation of effective interventions. The purpose of this study is to assess the status of health facilities utilization and predictors for health-seeking behavior of mothers/caregivers of under-five children with acute diarrhea in slums of Addis Ababa, Ethiopia. A community-based cross-sectional study design was employed in five rounds of surveys in seven kebeles in slums of Addis Ababa among 472 mothers/caregivers of 472 under-five children with acute diarrhea in reference to Andersen's behavioral model. Data were entered into EpiData Version 3.1 and analyzed using STATA Version 14.0. Descriptive statistics were used to examine patterns of health facilities utilization and multivariable logistic regression analysis was applied to identify predictors associated with health-seeking behavior. Most mothers/caregivers (70.8%) sought care either at home (14.2%) or health facilities (56.6%), whereas 29.2% reported that they did not seek any care. Of those who consulted health facilities, government health facilities (76.9%) were more utilized than private (18.0%) and informal (5.1%) health facilities. Nearly all (93.9%) of the mothers/caregivers using government health facilities used health centers, and of those who took their children to private health facilities (60.9%) used clinics and 26.1% used pharmacies/drug vendors. Mothers/caregivers visiting health facilities obtained mainly oral rehydration salt (ORS) (39.8%) and home-recommended fluids (HRF) (40.3%), but few of them (11.9%) obtained ORS plus zinc supplementation. Predisposing factors of literacy of mothers/caregivers (adjusted odds ratio (AOR) = 2.4; 95% CI 1.4-4.1) and occupation (AOR = 2.6; 95% CI 1.5-4.6), the enabling factors of households monthly income of 50 United States Dollars (US$) and above (AOR = 2.9; 95% CI 1.5-5.6) and availability of nearest health

    Objective: To evaluate the clinical effects of comprehensive therapy of psychological intervention and rehabilitation training on the mental health of the patients with acute stroke. Methods: A total of 120 patients with acute stroke were randomly divided into trial group and control group. Both groups were given the corresponding drug therapy, medical basic nursing and convention nursing. Besides, psychological intervention and comprehensive rehabilitation training were added to the trial group. SCL-90, Europ stroke scales (ESS) score were assessed with each patient on day 3 for the first time and on day 21 for the second time;Barthel index was assessed on the day 90. Results: After psychological intervention, SCL-90 declined significantly in the trial group comparing with the control group, there were signicant differences in the somatization, obsession, depression, anxiety, fear, ESS score, Barthel index and other psychological factors between the trial group and control group (P<0.05). Conclusions:Comprehensive therapy of early psychological intervention and rehabilitation training can significantly improve the mental health, limb movement function, stress ability and activity of daily living on the patients with acute stroke.

    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.

    Indoor air quality can conceivably be impacted by hundreds of different chemicals. More than 900 different organic compounds alone have been identified in indoor air. The health effects that could potentially arise from exposure to individual pollutants or mixtures of pollutants cover the full range of acute and chronic effects, including largely reversible responses, such as rashes and irritations, as well as irreversible toxic and carcinogenic effects. These indoor contaminants are emitted from a large variety of materials and substances that are widespread components of everyday life. Pacific Northwest Laboratory conducted a search of the peer-reviewed literature on health effects associated with indoor air contaminants for the Bonneville Power Administration to aid the agency in the preparation of environmental documents. The results of this search are reported in two volumes. Volume 1 is a summary of the results of the literature search; Volume 2 is the complete results of the literature search and contains all references to the material reviewed. 16 tabs.

    Rhinosinusitis is one of the more common diseases encountered in outpatient visits to health care. The objective of this study was to determine the most cost-effective antibiotic treatment for patients with acute (RSA) and chronic rhinosinusitis (RSC) that is available at the Mexican Institute of Social Security (IMSS). Cost-effectiveness analysis of RSA and RSC treatment from an institutional perspective. Effectiveness outcome was defined as the percentage of cure. A decision tree with a Bayesian approach included the following therapeutic alternatives: ciprofloxacin, gatifloxacin, trimetoprim/sulfametoxazol (TMP/SMX), amoxicilin/clavulanic acid (AAC) and clindamicin. Treatment for RSA with AAC showed a mean cost per cured patient of $ 878 pesos. The remaining antibiotics had a higher cost per unit of success, and therefore the results showed that AAC was the best alternative considering this criterion. The therapy that showed a larger percentage of cured patients in RSC was clindamicin; however, the therapeutic alternative with the lowest cost per successful unit was the one based on ciprofloxacin, which dominates gatifloxacin and AAC. The most cost-effective alternative in the antibiotic treatment of patients with RSA was ACC while for RSC it was ciprofloxacin; sensitivity analysis showed the strength of the base study results.

We aimed to develop a strategy to identify hospitalizations for AECOPD in secondary care data and to investigate the validity of strategies to identify hospitalizations for AECOPD in primary care data. Methods: We identified patients with chronic obstructive pulmonary disease (COPD in the Clinical Practice Research Datalink (CPRD with linked Hospital Episodes Statistics (HES data. We used discharge summaries for recent hospitalizations for AECOPD to develop a strategy to identify the recording of hospitalizations for AECOPD in HES. We then used the HES strategy as a reference standard to investigate the positive predictive value (PPV and sensitivity of strategies for identifying AECOPD using general practice CPRD data. We tested two strategies: 1 codes for hospitalization for AECOPD and 2 a code for AECOPD other than hospitalization on the same day as a code for hospitalization due to unspecified reason. Results: In total, 27,182 patients with COPD were included. Our strategy to identify hospitalizations for AECOPD in HES had a sensitivity of 87.5%. When compared with HES, using a code suggesting hospitalization for AECOPD in CPRD resulted in a PPV of 50.2% (95

    Full Text Available Acute respiratory infection is a major contributor to morbidity and mortality among children under five years of age in Ethiopia. While facilities have been implemented to address this problem they are underused due to a lack in help-seeking behavior. This study investigates factors related to the help-seeking behavior of mothers for children with acute respiratory infection using data from the 2011 Ethiopia Demographic and Health Survey.Data on 11,030 children aged 0-59 months obtained through interviewing women aged 15-49 years throughout Ethiopia was available. Descriptive statistics and logistic regression analyses were performed to determine which factors are related to help-seeking behavior for acute respiratory infection.In the two weeks prior to the survey, 773(7% of the children were reported to have symptoms of acute respiratory infection while treatment was sought for only 209 (27.2%. The odds ratio for acute respiratory infection was 1.6 (95% CI: 1.2-2.0 for rural residence with only 25.2% of these mothers seeking help compared to 46.4% for mothers with an urban residence. Smaller family size, younger mothers' age and having had prenatal care had a statistically significant odds ratio greater than 1 for both urban and rural residences. Highest wealth index had a statistically significant odds ratio greater than 1 for rural residence only, whereas primary education or higher had a statistically significant odds ratio greater than 1 for urban residence.Children from rural areas are more at risk for acute respiratory infection while their mothers are less likely to seek help. Nevertheless, there is also underuse of available services in urban areas. Interventions should target mothers with less education and wealth and older mothers. Expanding prenatal care among these groups would encourage a better use of available facilities and subsequently better care for their children.

    The media can be a powerful teacher of children and adolescents and have a profound impact on their health. The media are not the leading cause of any major health problem in the United States, but they do contribute to a variety of pediatric and adolescent health problems. Given that children and teens spend >7 hours a day with media, one would think that adult society would recognize its impact on young people's attitudes and behaviors. Too little has been done to protect children and adolescents from harmful media effects and to maximize the powerfully prosocial aspects of modern media.

    CHEM{_}MACCS has been developed from the radiological accident consequence code, MACCS, to perform probabilistic calculations of potential off-site consequences of the accidental atmospheric release of hazardous chemicals. The principal phenomena considered in CHEM{_}MACCS are atmospheric transport, mitigative actions based on dose projection, dose accumulation by a number of pathways, and early and latent health effects. CHEM{_}MACCS provides the following capabilities: (1) statistical weather sampling data (8,760 hourly data points per year), (2) population dose and health effect risk calculations based on site-specific population data, (3) health effects calculations including the consideration of potential site specific mitigative actions (evacuation and shielding), and (4) modeling of multiple release segments. Three different sample problems are contained in this report to show how to use CHEM{_}MACCS. Three test problems are run to compare CHEM{_}MACCS and D2PC. The doses versus the downwind centerline distances from the source for the given doses are in very close agreement.

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.

    Full Text Available Acute agitation occurs in a variety of medical and psychiatric conditions, and the management of agitated, abusive, or violent patients is a common problem in the emergency department. Rapid control of potentially dangerous behaviors by physical restraint and pharmacologic tranquillization is crucial to ensure the safety of the patient and health-care personnel and to allow diagnostic procedures and treatment of the underlying condition. The purpose of this article (the second in a 2-part series is to review published data on the efficacy and safety of antipsychotic medications currently available for managing situations of this type. Arrhythmias caused by QT-prolonging drugs occur infrequently, and multiple factors are often involved, including concomitant use of other drugs affecting the same pathway (most antipsychotic drugs prolong the QT interval by blocking potassium IKr current in HERG channels of myocardial cells, electrolyte disorders and, possibly, genetic predisposition. Judicious use of typical antipsychotics (mainly haloperidol and benzodiazepines (mainly lorazepam, given intramuscularly alone or in combination, has proved to be safe and effective for controlling acute motor agitation related to psychiatric illness; cocaine, methamphetamine, and ethanol toxicity; ethanol withdrawal; and other factors. They are still widely used and are particularly useful when limited data are available on the patient’s history of cardiovascular disease, current use of medication, and/or the likelihood of illicit drug or alcohol intoxication; when the diagnosis involves medical comorbidity or intoxication; or when there is no specific treatment (e.g., personality disorders, learning disabilities, mental retardation, organic brain damage. If rapid tranquillization is necessary before a formal diagnosis can be made and there are uncertainties regarding the patient’s medical history, lorazepam is often considered the first-line drug of choice.

    Objective.To examine the procoagulant effects of thrombolytic agent on hemostasis and study the role of hemostatic markers as predictors of clinical outcomes.Methods.In the present study,eighteen patients with acute myocardial infarction(AMI) received 1.5 or 2.0 million U nonspecific urokinase(UK),or 70~80 mg fibrin specific recombinant tissue plasminogen activator(rt PA)and did not use heparin until 8 hours after intravenous injection of the above agents.Eight patients with AMI and without thrombolytic therapy were enrolled as controls.Coagulant and thrombolytic activity markers included thrombin antithrombin Ⅲ complex (TAT),D dimer,fibrinogen (Fg),FMPV/Amax.All markers were determined before,immediately,1,2,4 and 8 hours after the administration of thrombolytic agents respectively. Results.Molecular marker of thrombin generation- - TAT showed an activated coagulant state immediately after thrombolytic therapy.Level of TAT showed no significant changes between every two observed phases in controls.However,level of TAT increased significantly from 4.95± 1.75μ g/L ( 4.63± 1.37μ g/L) to 14.71± 3.31μ g/L ( 14.25± 2.53μ g/L) before and immediately after administration of thrombolytic agents UK(or rt PA).There was significant difference between level of serum TAT of patients with and without thrombolytic therapy (P< 0.05).Patients achieving clinical reperfusion had lower TAT level than those failing in thrombolytic therapy,and higher FMPV/Amax level than controls.D dimer,a surrogate of thrombolytic activity increased markedly and Fg significantly declined after thrombolytic therapy(P< 0.05). Conclusions.Thrombin generation occurred in plasma in response to excess fibrinolysis induced by thrombolytic therapy.Both urokinase and rt PA had procoagulant action.This transient activation of the coagulant system might contribute to early reocclusion.These data provided the theoretical support for simultaneous administration of anticoagulant therapy with thrombolytic

    Previous work in animals has shown that dopamine (DA) in cortex and striatum plays an essential role in stress processing. For the first time, we systematically reviewed the in vivo evidence for DAergic stress processing in health and psychopathology in humans. All studies included (n studies=25, n observations=324) utilized DA D2/3 positron emission tomography and measured DAergic activity during an acute stress challenge. The evidence in healthy volunteers (HV) suggests that physiological, but not psychological, stress consistently increases striatal DA release. Instead, increased medial prefrontal cortex (mPFC) DAergic activity in HV was observed during psychological stress. Across brain regions, stress-related DAergic activity was correlated with the physiological and psychological intensity of the stressor. The magnitude of stress-induced DA release was dependent on rearing conditions, personality traits and genetic variations in several SNPs. In psychopathology, preliminary evidence was found for stress-related dorsal striatal DAergic hyperactivity in psychosis spectrum and a blunted response in chronic cannabis use and pain-related disorders, but results were inconsistent. Physiological stress-induced DAergic activity in striatum in HV may reflect somatosensory properties of the stressor and readiness for active fight-or-flight behavior. DAergic activity in HV in the ventral striatum and mPFC may be more related to expectations about the stressor and threat evaluation, respectively. Future studies with increased sample size in HV and psychopathology assessing the functional relevance of stress-induced DAergic activity, the association between cortical and subcortical DAergic activity and the direct comparison of different stressors are necessary to conclusively elucidate the role of the DA system in the stress response.

    Hospital-acquired acute kidney injury (HA-AKI) is a potentially preventable cause of morbidity and mortality. Identifying high-risk patients prior to the onset of kidney injury is a key step towards AKI prevention. A national retrospective cohort of 1,620,898 patient hospitalizations from 116 Veterans Affairs hospitals was assembled from electronic health record (EHR) data collected from 2003 to 2012. HA-AKI was defined at stage 1+, stage 2+, and dialysis. EHR-based predictors were identified through logistic regression, least absolute shrinkage and selection operator (lasso) regression, and random forests, and pair-wise comparisons between each were made. Calibration and discrimination metrics were calculated using 50 bootstrap iterations. In the final models, we report odds ratios, 95% confidence intervals, and importance rankings for predictor variables to evaluate their significance. The area under the receiver operating characteristic curve (AUC) for the different model outcomes ranged from 0.746 to 0.758 in stage 1+, 0.714 to 0.720 in stage 2+, and 0.823 to 0.825 in dialysis. Logistic regression had the best AUC in stage 1+ and dialysis. Random forests had the best AUC in stage 2+ but the least favorable calibration plots. Multiple risk factors were significant in our models, including some nonsteroidal anti-inflammatory drugs, blood pressure medications, antibiotics, and intravenous fluids given during the first 48 h of admission. This study demonstrated that, although all the models tested had good discrimination, performance characteristics varied between methods, and the random forests models did not calibrate as well as the lasso or logistic regression models. In addition, novel modifiable risk factors were explored and found to be significant. Published by Oxford University Press on behalf of the American Medical Informatics Association 2015.

    Background and Aim: Studies on potential biomarkers in experimental models of acute lung injury (ALI) and clinical samples from patients with ALI have provided evidence to the pathophysiology of the mechanisms of lung injury and predictor of clinical outcome. Because of the high mortality and substantial variability in outcomes in patients with acute respiratory distress syndrome (ARDS), identification of biomarkers such as cytokines is important to determine prognosis and guide clinical decision-making. Materials and Methods: In this study, we have included thirty patients admitted to Intensive Care Unit diagnosed with ARDS, and serum samples were collected on day 1 and 7 and were analyzed for serum interleukin-6 (IL-6) and IL-8 by ELISA method, and Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring was done on day 1. Results: The mortality in the patients observed with ARDS was 34%. APACHE II score was significantly higher in nonsurvivors as compared to survivors. There were no significant differences in gender and biochemical and hematological parameters among the survivors and nonsurvivors. Serum IL-6 and IL-8 levels on day 1 were significantly higher in all the ARDS patients as compared to healthy controls and these levels were returned to near-normal basal levels on day 7. The serum IL-6 and IL-8 levels measured on day 7 were of survivors. As compared to survivors, the IL-6 and IL-8 levels were significantly higher in nonsurvivors measured on day 1. Spearman's rank correlation analysis indicated a significant positive correlation of APACHE II with IL-8. By using APACHE II score, IL-6, and IL-8, the receiver operating characteristic curve was plotted and the provided predictable accuracy of mortality (outcome) was 94%. Conclusion: The present study highlighted the importance of measuring the cytokines such as IL-6 and IL-8 in patients with ARDS in predicting the clinical outcome. PMID:27688627

    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.

    Full Text Available Healthcare delivery systems are facing fundamental challenges. New ways of organising theses systems based on the different needs of stakeholders’ are required to meet these challenges. While medicine is currently undergoing remarkable developments from its morphological and phenotype orientation to a molecular and genotype orientation, promoting the importance of prognosis and prediction, the discussion about the relevance of genome-based information and technologies for the health care system as a whole and especially for public health is still in its infancy. The following article discusses the relevance of genome-based information and technologies for individual health information management, health policy development and effective health services.

    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.

    Stable tendency to perseverative thoughts such as trait rumination and worry can influence somatic health. The purpose of the study was to investigate the relationship between perseverative thoughts and somatic complaints, and the possible mediating effects of perceived stress, negative and positive affectivity in adolescence. Having an acute or a chronic condition was also assessed to be controlled for and to reveal their effects on symptom reporting. Three hundred and six adolescents from 7th to 12th grade with mean age of 16.33 (SD = 1.29) participated in the study. Mediation analysis suggested that impact of trait-like perseverative thoughts on complaints were mediated by perceived stress and negative affectivity. Having an acute condition had also an effect on symptom reporting through increased negative affectivity. Our results highlight that ruminations or worry as stable intrapersonal characteristics are relevant processes in health and can be potential targets in prevention programmes in adolescence.

    Although adolescent cigarette smoking remains a critical public health concern, little is known about the reinforcing mechanisms governing smoking in this vulnerable population. To assess predictions derived from both positive and negative reinforcement models of drug use, the authors measured the acute effects of nicotine, as administered via tobacco cigarettes, on both positive and negative affect in a group of 15- to 18-year-old smokers. A matched group of nonsmokers served as a comparison group. Findings revealed that whereas adolescents who smoked a cigarette experienced reductions in both positive and negative affect, the observed reductions in negative affect were moderated by nicotine content of the cigarette (high yield vs. denicotinized), level of nicotine dependence, level of baseline craving, and smoking expectancies pertinent to negative affect regulation. Nonsmokers experienced no change in affect over the 10-min assessment period, and no interaction effects were observed for positive affect. Overall, the findings conform to a negative reinforcement model of nicotine effects and strongly suggest that, even among young light smokers, nicotine dependence and resultant withdrawal symptomatology may serve as motivating factors governing smoking behavior.

    Effects of the effective components group of Xiaoshuantongluo formula (XECG) on rat acute blood stasis model were studied under the guidance of the concept of effective components group. Rat acute blood stasis model was induced by subcutaneous injection of epinephrine combined with ice water bath. Hemorheology indices such as whole blood viscosity, plasma viscosity, erythrocyte aggregation index and platelet aggregation rate; coagulation parameters including PT, APTT, TT and FIB; 6-keto-PGF1alpha, TXB2 and D-dimer levels were determined to evaluate the effects of XECG. The results showed that XECG significantly reduced ADP-induced platelet aggregation, but showed little influence on the whole blood viscosity, plasma viscosity and erythrocyte aggregation rate. XECG extended PT and TT slightly, but had no effects on APTT and FIB content. D-dimer levels significantly decreased after administration of XECG with a little decrease of TXB2, but the content of 6-keto-PGF1alpha did not change significantly. The results suggest that the role of XECG of anti-aggregation is more prominent.

    Guinea pigs were sensitized with trinitrophenylated liver macromolecular protein fraction (TNP-LP1) prepared by using sodium trinitrobenzenesulfonate of strong immunogenicity as the hapten and LP1 as the carrier protein. The administration of trinitrophenylated hepatocytes and lipopolysaccharide to these TNP-LP1-sensitized guinea pigs through the mesenteric vein 2 weeks later resulted in the induction of acute hepatic failure accompanied by massive hepatic cell necrosis in almost all of the guinea pigs. Using this experimental model, the effect of Gomisin A on the induction of immunological acute hepatic failure was examined. As a result, the administration of gomisin A remarkably improved the survival rate and serum transaminase levels of the immunologically-induced acute hepatic failure guinea pigs. Gomisin A also improved the histological changes of the liver in these guinea pigs. These results suggested that gomisin A is effective for the improvement of immunologically-induced acute hepatic failure in our experimental model.

    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.

    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.

    We assessed the impact of unemployment benefit programs on the health of the unemployed. We linked US state law data on maximum allowable unemployment benefit levels between 1985 and 2008 to individual self-rated health for heads of households in the Panel Study of Income Dynamics and implemented state and year fixed-effect models. Unemployment was associated with increased risk of reporting poor health among men in both linear probability (b=0.0794; 95% confidence interval [CI]=0.0623, 0.0965) and logistic models (odds ratio=2.777; 95% CI=2.294, 3.362), but this effect is lower when the generosity of state unemployment benefits is high (b for interaction between unemployment and benefits=-0.124; 95% CI=-0.197, -0.0523). A 63% increase in benefits completely offsets the impact of unemployment on self-reported health. Results suggest that unemployment benefits may significantly alleviate the adverse health effects of unemployment among men.

  17. [Cost effectiveness and health sector reform].

    Science.gov (United States)

    Musgrove, P

    1995-01-01

    The cost-effectiveness of a health intervention is an estimate of the relation between what it costs to be provided, and the improvement in health which results from such intervention. Health may improve because the incidence of illness or injury is reduced, because death is avoided or delayed, or because the duration or severity of disability is limited. The calculation of this health benefit combines objective factors, such as the age at incidence and whether or not the outcome is death, with subjective factors such as the severity of disability, the judgement as to the value of life lived at different ages, and the rate at which the future is discounted. The construction and interpretation of the estimate are explained. Also, the paper examines whether the concept of cost-effectiveness is consistent with ethical norms such as equity, and concludes that they are not in conflict. Finally, it addresses the question of how to incorporate cost-effectiveness into a health sector reform, and possible ways to implement it.

    High sugar consumption elicits numerous deleterious effects on health by inducing insulin resistance, which is closely associated with the development of metabolic disorders such as obesity or type-2 diabetes. Furthermore, there is also growing evidence that caffeine may play an important role in the regulation of insulin release and the appearance of related metabolic impairments. Thus, the aim of this work was to investigate the impact of acute sugar and caffeine intake on the metabolic health status by using a metabolomic multi-platform based on the combination of flow injection mass spectrometry and ultra-high performance liquid chromatography mass spectrometry. To this end, we performed a randomized, crossover and double-blind intervention study with different soft drinks from the same brand. Numerous metabolomic changes were detected in serum samples over time after the intake of sugar-sweetened beverages, including energy-related metabolites, amino acids and lipids, thus demonstrating the intense effects provoked by acute sugar consumption on the organism during 3 h of follow-up. However, the most significant findings were observed after the co-ingestion of caffeine, which could be indicative of a synergic effect of this psychostimulant on insulin-mediated perturbations. © 2017 WILEY-VCH Verlag GmbH & Co.

    Because of its public health, ecological and industrial consequences, the Chernobyl accident has become a myth which serves as the focus of many fears, justified or not. no one can question the seriousness of the event, but after fifteen years there is still no agreement about the effect it has had or will have on public health. For example, the total number of deaths attributed to Chernobyl varies from less than a hundred to several millions and congenital malformations from negligible to cataclysmic. Effects on public health may be calculated from data on contamination, from the dose received and from the risk, all three of which are likely to be very roughly known; or they may be evaluated on the spot, either by epidemiological studies or by examining medical registers. This report makes an inventory of the different risks and takes stock on them. (N.C.)

    Full Text Available Polydextrose (PDX is a non-digestible oligosaccharide used widely across most sectors of the food industry. It is a randomly linked glucose oligomer containing small amounts of sorbitol and citric acid. The random bonds in PDX prevent mammalian digestive enzymes from readily hydrolyzing the molecule and it has a reported energy value of 1 kcal/g. These properties have led to the acceptance in many countries that PDX provides similar physiological effects as other dietary fibers and has shown prebiotic potential. Dietary intervention with prebiotics has been shown to selectively stimulate the growth and/or activity of one or a limited number of intestinal bacteria associated with several physiological benefits on health. Therefore, the objective of this review was a survey of the literature on the effect of supplementation with PDX in health, and to list the benefits for maintaining health and/or reducing the development of diseases.

    This study aimed to examine whether social capital (bonding and bridging social capital) attenuate the effect of low functional health literacy on health information resources, efficacy, and behaviors. In-person interviews were conducted with 1,000 residents in Seoul, Korea, in 2011. The authors found that respondents' functional health literacy had positive effects on the scope of health information sources and health information self-efficacy but not health information-seeking intention. Respondents' social capital had positive effects on the scope of health information sources, health information efficacy, and health information-seeking intention. The authors found (a) a significant moderation effect of bridging social capital on the relation between health literacy and health information self-efficacy and (b) a moderation effect of bonding social capital on the relation between health literacy and health information-seeking intention.

    Carbon dioxide (CO2) originates from human metabolism and typically remains about 10-fold higher in concentration on the International Space Station (ISS) than at the earth's surface. There have been recurring complaints by crew members of episodes of "mental viscosity" adversely affecting their performance, and there is evidence from the ISS that associates CO2 levels with reports of headaches by crewmembers. Consequently, flight rules have been employed to control CO2 below 3 mm Hg, which is well below the existing Spacecraft Maximum Allowable Concentration (SMAC) of 10 mm Hg for 24-hour exposures, and 5.3 mm Hg for exposures of 7 to 180 days. Headaches, while sometime debilitating themselves, are also symptoms that can provide evidence that physiological defense mechanisms have been breached, and there is evidence that CO2 has effects at levels below the threshold for headaches. This concern appears to be substantiated in reports that CO2 at concentrations below 2 mm Hg substantially reduced some cognitive functions that are associated with the ability to make complex decisions in conditions that are characterized by volatility, uncertainty, complexity, ambiguity, and delayed feedback. These are conditions that could be encountered by crews in off-nominal situations or during the first missions beyond low earth orbit. Therefore, we set out to determine if decision-making under volatile, uncertain, confusing and ambiguous circumstances, where feedback is delayed or absent, is correlated with low levels of CO2 during acute exposures (several hours) in crew-like subjects and to determine if additional cognitive domains are sensitive to concentrations of CO2 at, or below, current ISS levels by using a test battery that is currently available onboard ISS. We enrolled 22 volunteers (8 females, 14 males) between the ages of 30-55 (38.8 +/- 7.0) years whose training and professional experience reflect that of the astronaut corps. Subjects were divided among 4 study

    Full Text Available Abstract Background The use of cardiovascular health services is greater among patients with depressive symptoms than among patients without. However, the extent to which such associations between depressive symptoms and health service utilization are attributable to variations in comorbidity and prognostic disease severity is unknown. This paper explores the relationship between depressive symptoms, health service cardiovascular consumption, and prognosis following acute myocardial infarction (AMI. Methods The study design was a prospective cohort study with follow-up telephone interviews of 1,941 patients 30 days following AMI discharged from 53 hospitals across Ontario, Canada between December 1999 and February, 2003. Outcome measures were post discharge use of cardiac and non-cardiac health care services. The service utilization outcomes were adjusted for age, sex, income, comorbidity, two validated measures of prognosis (cardiac functional capacity and risk adjustment severity index, cardiac procedures (CABG or PTCA and drugs prescribed at discharge. Results Depressive symptoms were associated with a 24% (Adjusted RR:1.24; 95% CI:1.19–1.30, P Conclusion Depressive symptoms are associated with significantly higher cardiac and non-cardiac health service consumption following AMI despite adjustments for comorbidity and prognostic severity. The disproportionately higher cardiac health service consumption among lower-risk AMI depressive patients may suggest that health seeking behaviors are mediated by psychosocial factors more so than by objective measures of cardiovascular risk or necessity.

    It is unclear whether antihypertensive treatment before stroke affects acute ischemic stroke severity and outcome. To evaluate this association, the authors studied 482 consecutive patients (age 78.8±6.7 years) admitted with acute ischemic stroke. Stroke severity was assessed at admission with the National Institutes of Health Stroke Scale (NIHSS). The outcome was assessed with rates of adverse outcome (modified Rankin scale at discharge ≥2). Independent predictors of severe stroke (NIHSS ≥16) were female sex and atrial fibrillation. Treatment with diuretics before stroke was associated with nonsevere stroke. At discharge, patients with adverse outcome were less likely to be treated before stroke with β-blockers or with diuretics. Independent predictors of adverse outcome were older age, higher NIHSS at admission, and history of ischemic stroke. Treatment with diuretics before stroke appears to be associated with less severe neurologic deficit in patients with acute ischemic stroke. © 2015 Wiley Periodicals, Inc.

    A case-control study of mortality from acute respiratory infections (ARI) among children under five years of age was conducted in Naucalpan, an urban-suburban area of Mexico City, and in rural localities of Tlaxcala, Mexico. The study found that ARI deaths tended to occur in the poorest neighborhoods; 78% of the deceased study subjects were infants under six months old; and 68% of the deaths occurred at home. Comparison of the data for cases (fatalities) and control children who had severe ARI but recovered showed that failure to receive antibiotics was associated with death (odds ratio 28.5, 95% confidence interval 2.1-393.4). This antibiotic effect was controlled for numerous potentially confounding factors. It is evident that antibiotics had a much greater effect in the early days of the illness than later on. In general, the findings strongly support PAHO/WHO primary health care strategies--including such strategies as standardized management of severe ARI cases--that seek to reduce childhood ARI mortality.

    The beneficial impact of beta blockade after an acute myocardial infarction (AMI) is clear, but beta-adrenergic blockers differ in multiple characteristics, including lipophilicity and selectivity. The impact of these factors on the effects of beta blockade is unknown. We therefore compared the effects of different beta blockers on mortality after AMI. Charts of 201,752 patients with AMI were abstracted by the Cooperative Cardiovascular Project, a quality assurance program sponsored by the Health Care Financing Administration. Of the 69,338 patients prescribed beta blockers, we compared mortality of patients receiving different beta-adrenergic blockers using the Cox proportional-hazards model accounting for multiple factors that might influence survival. The mortality rates of the 2 selective agents, metoprolol and atenolol, were virtually identical (13.5% and 13.4% 2-year mortality, respectively). Compared with metoprolol, patients discharged on propranolol had a slightly increased mortality (15.9% 2-year mortality), which may be related to undetected differences at baseline. Survival with all of the drugs was superior to the 23.9% 2-year mortality seen in patients not receiving beta blockers. Beta blockade overall was associated with a 40% improvement in survival. Although the use of beta blockade after AMI has major prognostic importance, the present study suggests that the specific beta blocker chosen will have little influence on mortality.

    Acetaminophen (APAP)-induced acute liver failure (ALF) is a serious health problem in developed countries. N-acetyl-l-cysteine (NAC), the current therapy for APAP-induced ALF, is not always effective, and liver transplantation is often needed. Opuntia spp. fruits are an important source of nutrients and contain high levels of bioactive compounds, including antioxidants. The aim of this study was to evaluate the hepatoprotective effect of Opuntia robusta and Opuntia streptacantha extracts against APAP-induced ALF. In addition, we analyzed the antioxidant activities of these extracts. Fruit extracts (800 mg/kg/day, orally) were given prophylactically to male Wistar rats before intoxication with APAP (500 mg/kg, intraperitoneally). Rat hepatocyte cultures were exposed to 20 mmol/L APAP, and necrosis was assessed by LDH leakage. Opuntia robusta had significantly higher levels of antioxidants than Opuntia streptacantha. Both extracts significantly attenuated APAP-induced injury markers AST, ALT and ALP and improved liver histology. The Opuntia extracts reversed APAP-induced depletion of liver GSH and glycogen stores. In cultured hepatocytes, Opuntia extracts significantly reduced leakage of LDH and cell necrosis, both prophylactically and therapeutically. Both extracts appeared to be superior to NAC when used therapeutically. We conclude that Opuntia extracts are hepatoprotective and can be used as a nutraceutical to prevent ALF. PMID:27782042

    Full Text Available Nutrition represents a summation of intake, absorption, storage and utilization of foods by the tissues. Oral tissues are one of the most sensitive indicators of nutritional state of the body. Nutritional deficiencies are associated with changes in the integrity (health and appearance of the oral structures/ tissues and these changes are frequently the first clinical signs of deficiency. Nutrition affects oral health and oral health affects nutrition. The effects of malnutrition can be seen in the oral structures in all stages of human growth and development from conception to old age. The consequence of certain oral diseases may compromise the nutrition by affecting the intake and mastication particularly in some vulnerable groups like people with severe caries, severe oral ulceration, advanced periodontal disease and the resulting edentulousness. The HIV pandemic has added another dimension to the issue of nutrition and oral health. Oral lesions are some of the earliest lesions seen in HIV/AIDS and 90% of HIV/AIDS patients will have oral lesions at a point in the course of the disease. These oral lesions are painful; disturb food intake and mastication thereby further compromising the nutrition of the affected individuals. In Africa, particularly the Sub-Saharan Africa, the burden of poverty, economic downturn and the HIV pandemic have added another dimension to the issue of food availability and nutrition. Malnutrition is a real problem in this area. This paper will examine the effects of compromised nutrition on oral health and the reverse.

    This article explores public relations effectiveness in public health institutions. First, the two major elements that comprise public relations effectiveness are discussed: reputation management and stakeholder relations. The factors that define effective reputation management are examined, as are the roles of issues and crisis management in building and maintaining reputation. The article also examines the major facets of stakeholder relations, including an inventory of stakeholder linkages and key audiences, such as the media. Finally, methods of evaluating public relations effectiveness at both the program level and the institutional level are explored.

  18. Therapeutic effect of ghrelin in the course of cerulein-induced acute pancreatitis in rats.

    Recent studies have shown that pretreatment with ghrelin exhibits protective effect in the gut. Administration of ghrelin reduces gastric mucosal damage, as well as inhibits the development of experimental pancreatitis. However, this protective effect requires administration of ghrelin before gastric or pancreatic damage and thus has a limited clinical value. The aim of present study was to assess the influence of ghrelin administered after development of acute pancreatitis on the course of this disease. Acute pancreatitis was induced by cerulein. Ghrelin was administered twice a day for 1, 2, 4, 6 or 9 days at the dose of 4, 8 or 16 nmol/kg/dose. The first dose of ghrelin was given 24 hours after last injection of cerulein. The severity of acute pancreatitis was assessed between 0 h and 10 days after cessation of cerulein administration. Administration of caerulein led to the development of acute edematous pancreatitis and maximal severity of this disease was observed 24 hours after induction of pancreatitis. Treatment with ghrelin reduced morphological signs of pancreatic damage such as pancreatic edema, leukocyte infiltration and vacuolization of acinar cells, and led to earlier regeneration of the pancreas. Also biochemical indexes of the severity of acute pancreatitis, serum activity of lipase and amylase were significantly reduced in animals treated with ghrelin. These effects were accompanied by an increase in the pancreatic DNA synthesis and a decrease in serum level of pro-inflammatory interleukin-1b. Administration of ghrelin improved pancreatic blood flow in rats with acute pancreatitis. We conclude that: (1) treatment with ghrelin exhibits therapeutic effect in caerulein-induced experimental acute pancreatitis; (2) this effect is related, at least in part, to the improvement of pancreatic blood flow, reduction in proinflammatory interleukin-1beta and stimulation of pancreatic cell proliferation.

    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.

    Full Text Available Recently, vibration has become very popular as a method of exercise and training and drawn attention of researchers. The aim of this study was to analyses the acute affect of vibration applications as a method of exercise and training on jumping performance.In this study experimental group consists of 25 subjects who are studying at Physical Education and Sports Department of Sakarya University (age 22.2±1.7 years, height 179.2±4.8 cm. body weight 71.5±9.0 kg. This study included a vibration at density of 35 Hz (3x30 sec. frequency that result from aerobic exercise that has low density and b just methods of aerobic exercise (without any vibration that has low density. Subjects have taken the tests of countermovement and squat jumping after 2 minutes of each application. All applications and tests have been done in nonconsecutive days in a random scheme. In statistical analysis Wilcoxon has been applied in nonparametric scheme.For counter movement jumping; height of jumping, the difference between before and after the application of vibration related to the point of peak power and average power has been found significiant (respectively, p0.05; p>0.05; p>0.05.As a result, it is concluded that vibration that is applied at the range of 35 Hz frequency could increase the performance of acute countermovement jumping.

    Full Text Available The acute phase of stroke is accompanied by functional changes in the activity and interplay of both hemispheres. In healthy subjects, gender is known to impact the functional brain organization.We investigated whether gender influences also acute stroke functional changes. In thirty-five ischemic stroke patients, we evaluated the excitability of the affected (AH and unaffected hemisphere (UH by measuring resting and active motor threshold and motor-evoked potential amplitude under baseline conditions and after intermittent theta burst stimulation (iTBS of AH. We also computed an index of the excitability balance between the hemispheres, laterality indexes (LI, to evidence hemispheric asymmetry. Active motor threshold differed significantly between AH and UH only in the male group (p=0.004, not in females (p>0.200, and both LIAMT and LIRMT were significantly higher in males than in females (respectively p=0.033 and p=0.042. LTP-like activity induced by iTBS in AH was more frequent in females. Gender influences the functional excitability changes that take place after human stroke and the level of LTP that can be induced by repetitive stimulation. This knowledge is of high value in the attempt of individualizing to different genders any non-invasive stimulation strategy designed to foster stroke recovery.

    Acute otitis media is the most common bacterial disease in children under five years; therefore, is one of the most common causes of pediatric consultation. Our objective was to determine the feasibility to consider this disease as a sentinel factor of medical attention. All the new cases of acute otitis media registered between 2008 and 2011 were collected and analyzed. Proportions, ratios, and incidence rates were determined. Also, the limits for proportions were calculated using mid P exact test. In children under five years, we observed 20 % of the cases of non-suppurative otitis media, and suppurative otitis media in 17 %. The reason for acute respiratory infection in relation to cases of otitis media in children of this age increased from 87:1 in 2008 to 53:1 in 2011. The reason of suppurative otitis media decreased in children under five years, even in 2009, when it was registered the highest number of new cases of acute respiratory infection. It was not feasible to determine if acute otitis media is a sentinel indicator; however, we could monitor medical attention indirectly.

    The effective delivery of health care to growing ethnic populations within the United States is a challenge for nurse practitioners. A breakdown in cross-cultural communication and understanding, which stems from the tendency of health care professionals to project their own culturally specific values and behaviors onto the foreign-born patient, has contributed significantly to non-compliance in this patient population. In order to remedy this situation, it is important for nurse practitioners to separate the values of their own cultural background from the cultural background and values of the patients for whom they provide care.

    Introduction Farm workers are at a very high risk of occupational diseases due to exposure to pesticides resulting from inadequate education, training and safety systems. The farm worker spends a lot of time exposed to these harmful agrochemicals. Numerous acute cases with symptoms typical of agrochemical exposure were reported from the commercial farms. We assessed the health effects of agrochemicals in farm workers in commercial farms of Kwekwe District (Zimbabwe), in 2006. Methods An analy...

    In Tlaxcala State, Mexico, we determined that 80% of children who died from diarrhoea or acute respiratory infections (ARI) received medical care before death; in more than 70% of the cases this care was provided by a private physician. Several strategies have been developed to improve physicians' primary health care practices but private practitioners have only rarely been included. The objective of the present study was to evaluate the impact of in-service training on the case management of diarrhoea and ARI among under-5-year-olds provided by private and public primary physicians. The training consisted of a five-day course of in-service practice during which physicians diagnosed and treated sick children attending a centre and conducted clinical discussions of cases under guidance. Each training course was limited to six physicians. Clinical performance was evaluated by observation before and after the courses. The evaluation of diarrhoea case management covered assessment of dehydration, hydration therapy, prescription of antimicrobial and other drugs, advice on diet, and counselling for mothers; that of ARI case management covered diagnosis, decisions on antimicrobial therapy, use of symptomatic drugs, and counselling for mothers. In general the performance of public physicians both before and after the intervention was better than that of private doctors. Most aspects of the case management of children with diarrhoea improved among both groups of physicians after the course; the proportion of private physicians who had five or six correct elements out of six increased from 14% to 37%: for public physicians the corresponding increase was from 53% to 73%. In ARI case management, decisions taken on antimicrobial therapy and symptomatic drug use improved in both groups; the proportion of private physicians with at least three correct elements out of four increased from 13% to 42%, while among public doctors the corresponding increase was from 43% to 78%.

    This work aims to test whether different segments of healthcare provision differentially attract private capital and thus offer heterogeneous opportunities for private investors' diversification strategies. Thomson Reuter's SDC Platinum database provided data on 2563 merger and acquisition (M&A) deals targeting healthcare providers in Western Europe between 1990 and 2010. Longitudinal trends of industrial and geographical characteristics of M&As' targets and acquirers are examined. Our analyses highlight: (i) a relative decrease of long-term care facilities as targets of M&As, replaced by an increasing prominence of general hospitals, (ii) a shrinking share of long-term care facilities as targets of financial service organizations' acquisitions, in favor of general hospitals, and (iii) an absolute and relative decrease of long-term care facilities' role as target of cross-border M&As. We explain the decreasing interest of private investors towards long-term care facilities along three lines of reasoning, which take into account the saturation of the long-term care market and the liberalization of acute care provision across Western European countries, regulatory interventions aimed at reducing private ownership to ensure resident outcomes and new cultural developments in favor of small-sized facilities, which strengthen the fragmentation of the sector. These findings advance the literature investigating the effect of private ownership on health outcomes in long-term facilities. Market, policy and cultural forces have emerged over two decades to jointly regulate the presence of privately owned, large-sized long-term care providers, seemingly contributing to safeguard residents' well-being.

  8. Likely health outcomes for untreated acute febrile illness in the tropics in decision and economic models; a Delphi survey.

    Directory of Open Access Journals (Sweden)

    Yoel Lubell

    Full Text Available BACKGROUND: Modelling is widely used to inform decisions about management of malaria and acute febrile illnesses. Most models depend on estimates of the probability that untreated patients with malaria or bacterial illnesses will progress to severe disease or death. However, data on these key parameters are lacking and assumptions are frequently made based on expert opinion. Widely diverse opinions can lead to conflicting outcomes in models they inform. METHODS AND FINDINGS: A Delphi survey was conducted with malaria experts aiming to reach consensus on key parameters for public health and economic models, relating to the outcome of untreated febrile illnesses. Survey questions were stratified by malaria transmission intensity, patient age, and HIV prevalence. The impact of the variability in opinion on decision models is illustrated with a model previously used to assess the cost-effectiveness of malaria rapid diagnostic tests. Some consensus was reached around the probability that patients from higher transmission settings with untreated malaria would progress to severe disease (median 3%, inter-quartile range (IQR 1-5%, and the probability that a non-malaria illness required antibiotics in areas of low HIV prevalence (median 20%. Children living in low transmission areas were considered to be at higher risk of progressing to severe malaria (median 30%, IQR 10-58% than those from higher transmission areas (median 13%, IQR 7-30%. Estimates of the probability of dying from severe malaria were high in all settings (medians 60-73%. However, opinions varied widely for most parameters, and did not converge on resurveying. CONCLUSIONS: This study highlights the uncertainty around potential consequences of untreated malaria and bacterial illnesses. The lack of consensus on most parameters, the wide range of estimates, and the impact of variability in estimates on model outputs, demonstrate the importance of sensitivity analysis for decision models

    Nicotine is a widely used addictive drug, with an estimated 73 million Americans 12 years of age or older having used a tobacco product in the last month, despite documented risks to personal health. Nicotine alters cognitive processes, which include effects on attention and impulsivity, a mechanism that may contribute to the addictive properties of the drug. Individuals with a variety of psychological disorders ranging from attention deficit hyperactivity disorder (ADHD) to schizophrenia smoke at a higher rate than the rest of the population and show deficits in impulse control. The present studies evaluated the effects of acute, chronic, and withdrawal from chronic nicotine on an operant task that measured premature and signaled nose pokes, as well as performance efficiency in C57BL/6J mice. Results indicate that acute nicotine (0.09 mg/kg intraperitoneally) does not alter the acquisition of the task, but does significantly increase performance efficiency once the behavior has been learned. In contrast, chronic nicotine (0, 6.3, 12.6, and 36 mg/kg/day subcutaneously) and withdrawal from chronic nicotine had no effect on performance efficiency. These results suggest that initial nicotine use may have beneficial effects on inhibitory control, but these effects are not maintained with chronic nicotine consumption as tolerance develops. The findings may provide an explanation for higher rates of smoking in patients with impulse control issues, as the smoking may represent an initial attempt at self-medication. PMID:23565938

    The purpose of this work is to analyse the effects on informal caregiver's health and lifestyle when living with a dependent person at home. A comparison will be made between this situation and other situations involving commitment of time and energy, taking into account gender and age differences in each stage of the life cycle. Cross-sectional study analysing secondary data. The method used for collecting information is the computer assisted personal interview carried out in selected homes by the Ministry of Health, Social Services and Equality. The study included 19,351 participants aged over 25 years who completed the 2011-2012 Spanish National Health Survey. This research is based on demographic information obtained from a Spanish National Health Survey (2011/12). Using an empirical framework, the Logit model was select and the data reported as odds ratio. The estimations were repeated independently by sub-groups of age and gender. The study showed that the health of people who share their lives with a dependent person is worse than those who do not have any dependent person at home (they are 5 times at higher risk of developing health problems). The study found that being a woman, advance age, low educational level and does not work, also has an influence. Being a caregiver reduces the likelihood of maintaining a healthy lifestyle through physical exercise, relaxation, or eating a balanced diet. Living with a dependent person reduces the likelihood of maintaining healthy lifestyles and worsens the state of health of family members. Significant differences in gender and age were found.

    controlled at levels that are well below current spacecraft limits. Our study will extend the earlier study to determine if crew-like subjects are similarly effected by CO2. In addition to employing the Strategic Management Simulation tool, we will use the Cognition battery of psychometric measures that are being utilized aboard the ISS. It will be important to learn, by using Cognition, if additional cognitive domains are sensitive to concentrations of CO2 at or below limits currently controlled by flight rules. While spaceflight Cognition data will greatly enhance the knowledge base related to inflight behavioral health and performance, some of the measures may be influenced by fatigue (related to sleep deprivation and or workload) and changes in circadian rhythms. Therefore our use of this battery of tests in a well-controlled, ground-based study that is free of these potential confounding influences will establish a baseline terrestrial data set against which Cognition data collected in flight may be assessed. The findings from this study will be useful to the NASA Toxicology Office and the National Research Council Committee on Toxicology, which assists NASA in setting environmental standards, for revision of the SMAC for CO2, and for designing further studies on effects of CO2 upon cognitive functions.

    In this work, we present ARIES* update: a system designed in order to facilitate the human health effects assessment produced by accidental release of toxic chemicals. The first version of ARIES was developed in relation to 82/501/EEC Directive about mayor accidents in the chemical industry. So, the first aim was the support of the effects assessment derived for the chemicals included into this directive. From this establishment, it was considered acute exposures for high concentrations. In this report, we present the actual methodology for considering other type of exposures, such as environmental and occupational. Likewise other versions, the methodology comprises two approaches: quantitative and qualitative assessments. Quantitative assessment incorporates the mathematical algorithms useful to evaluate the effects produced by the most important routes of exposure: inhalation, ingestion, eye contact and skin absorption, in a short, medium and long term. It has been included models that realizes an accurate quantification of doses, effects,... and so on, such as simple approaches when the available information is not enough. Qualitative assessment, designed in order to complement or replace the previous one, is incorporated into an informatics system, developed in Clipper. It executes and displays outstanding and important toxicological information of about 100 chemicals. This information comes from ECDIN (Environmental Chemicals Data and Information Network) database through a collaboration with JRC-ISPRA working group. (Author) 24 refs.

    Full Text Available We all know that 2014 has been declared as the hottest year globally by the Meteorological department of United States of America. Climate change is a global challenge which is likely to affect the mankind in substantial ways. Not only climate change is expected to affect physical health, it is also likely to affect mental health. Increasing ambient temperatures is likely to increase rates of aggression and violent suicides, while prolonged droughts due to climate change can lead to more number of farmer suicides. Droughts otherwise can lead to impaired mental health and stress. Increased frequency of disasters with climate change can lead to posttraumatic stress disorder, adjustment disorder, and depression. Changes in climate and global warming may require population to migrate, which can lead to acculturation stress. It can also lead to increased rates of physical illnesses, which secondarily would be associated with psychological distress. The possible effects of mitigation measures on mental health are also discussed. The paper concludes with a discussion of what can and should be done to tackle the expected mental health issues consequent to climate change.

    In conscious rats implanted with an intracerebroventricular (icv) cannula, effect of icv injections of histamine, chlorpheniramine (H(1)-receptor antagonist) and ranitidine (H(2)-receptor blocker) was investigated in a rat model of acute trigeminal pain. Acute trigeminal pain was induced by putting a drop of 5 M NaCl solution on the corneal surface of the eye and the numbers of eye wipes were counted during the first 30 s. Histamine (20, 40 microg) and chlorpheniramine (80 microg) significantly decreased the numbers of eye wipes. Ranitidine alone had no effect. Pretreatment with chlorpheniramine did not change the histamine-induced analgesia, whereas the histamine effect on pain was inhibited with ranitidine pretreatment. These results indicate that the brain histamine, through central H(2) receptors, may be involved in the modulation of the acute trigeminal pain in rats.

    The tricyclic antidepressant imipramine has recently emerged as a cytoprotective agent, exerting beneficial effects in inflammatory tissue injury. The present study aimed to investigate therapeutic effects of imipramine in murine model of endotoxin-induced acute lung injury. Mice were administrated intraperitoneally with LPS (lipopolysaccharide) from Escherichia coli or vehicle. Imipramine was administrated intraperitoneally 30 min before LPS challenge. Pretreatment of mice with imipramine reduced lethality. Impramine also significantly attenuated lung inflammation, lung edema, MPO (myeloperoxidase) activity, lung tissue pathological changes and nuclear factor-kappaB DNA binding activity. The results of this study suggest that imipramine can exert protective effects in endotoxin-induced acute lung injury by suppressing nuclear factor-kappaB-mediated expression of inflammatory genes. Thus, imipramine could be a potential novel therapeutic agent for the treatment for acute lung injury.

    2016-10-18

    Aristolochic acid nephropathy (AAN) is a progressive kidney disease caused by a Chinese herb containing aristolochic acid. Excessive death of renal tubular epithelial cells (RTECs) characterized the acute phase of AAN. Therapies for acute AAN were limited, such as steroids and angiotensin-receptor blockers (ARBs)/angiotensin-converting enzyme inhibitors (ACEIs). It was interesting that, in acute AAN, female patients showed relative slower progression to renal failure than males. In a previous study, female hormone 17β-estradiol (E2) was found to attenuate renal ischemia-reperfusion injury. Thus, the aim of this study was to investigate the potential protective role of E2 in acute AAN. Compared with male C57BL/6 mice of acute AAN, lower serum creatinine (SCr) and less renal injury, together with RTEC apoptosis in females, were found. Treatment with E2 in male AAN mice reduced SCr levels and attenuated renal tubular injury and RTEC apoptosis. In the mice kidney tissue and human renal proximal tubule cells (HK-2 cells), E2 both attenuated AA-induced cell apoptosis and downregulated the expression of phosphor-p53 (Ser15), p53, and cleaved-caspase-3. This study highlights that E2 exhibited protective effects on the renal injury of acute AAN in male mice by reducing RTEC apoptosis, which might be related to inhibiting the p53 signaling pathway.

    AIM: To determine whether thalidomide prevents microvascular injury in acute radiation proctitis in white rats. METHODS: Fourteen female Wistar rats were used:six in the radiation group,six in the thalidomide group,and two in normal controls.The radiation and thalidomide groups were irradiated at the pelvic area using a single 30 Gy exposure.The thalidomide (150 mg/kg) was injected into the peritoneum for 7 d from the day of irradiation.All animals were sacrificed and the rectums were removed on day 8 after irradiation.The microvessels of resected specimens were immunohistochemically stained with thrombomodulin (TM),yon Willebrand Factor (vWF),and vascular endothelial growth factor (VEGF).RESULTS: The microscopic scores did not differ significantly between the radiation and thalidomide groups,but both were higher than in the control group.Expression of TM was significantly lower in the endothelial cells (EC) of the radiation group than in the control and thalidomide groups (P < 0.001).The number of capillaries expressing vWF in the EC was higher in the radiation group (15.3 ± 6.8) than in the control group (3.7 ± 1.7),and the number of capillaries expressing vWF was attenuated by thalidomide (10.8 ± 3.5,P < 0.001).The intensity of VEGF expression in capillaries was greater in the radiation group than in the control group and was also attenuated by thalidomide (P = 0.003).CONCLUSION: The mechanisms of acute radiationinduced proctitis in the rats are related to endothelial cell injury of microvessel,which may be attenuated with thalidomide.

In statistical analysis Wilcoxon has been applied in nonparametric scheme. For counter movement jumping; height of jumping,  the difference between before and after  the application of vibration related to the point of peak power and average power has been found significiant (respectively, p<0.05; p<0.05; p<0.01. In addition to this, no statistical difference was found for squat vertical jumping before and after the application of vibration related to the point of peak power and average power (respectively, p>0.05; p>0.05; p>0.05. As a result, it is concluded that vibration that is applied at the range of 35 Hz frequency could increase the performance of acute countermovement jumping.

    While it is recognised that effective health care teams are associated with quality patient care, the literature is comparatively sparse in defining the outcomes of effective teamwork. This literature review of the range of organisational, team and individual benefits of teamwork complements an earlier article which summarised the antecedent conditions for (input) and team processes (throughput) of effective teams. This article summarises the evidence for a range of outcome measures of effective teams. Organisational benefits of teamwork include reduced hospitalisation time and costs, reduced unanticipated admissions, better accessibility for patients, and improved coordination of care. Team benefits include efficient use of health care services, enhanced communication and professional diversity. Patients report benefits of enhanced satisfaction, acceptance of treatment and improved health outcomes. Finally, team members report enhanced job satisfaction, greater role clarity and enhanced well-being. Due to the inherent complexity of teamwork, a constituency model of team evaluation is supported where key stakeholders identify and measure the intended benefits of a team.

    Organizational health culture is a health-oriented core characteristic of the organization that is shared by all members. It is effective in regulating health-related behavior for employees and could therefore influence the effectiveness of health promotion efforts among organizations and employees. This study applied a multilevel analysis to verify the effects of organizational health culture on the organizational and individual effectiveness of health promotion. At the organizational level, we investigated the effect of organizational health culture on the organizational effectiveness of health promotion. At the individual level, we adopted a cross-level analysis to determine if organizational health culture affects employee effectiveness through the mediating effect of employee health behavior. The study setting consisted of the workplaces of various enterprises. We selected 54 enterprises in Taiwan and surveyed 20 full-time employees from each organization, for a total sample of 1011 employees. We developed the Organizational Health Culture Scale to measure employee perceptions and aggregated the individual data to formulate organization-level data. Organizational effectiveness of health promotion included four dimensions: planning effectiveness, production, outcome, and quality, which were measured by scale or objective indicators. The Health Promotion Lifestyle Scale was adopted for the measurement of health behavior. Employee effectiveness was measured subjectively in three dimensions: self-evaluated performance, altruism, and happiness. Following the calculation of descriptive statistics, hierarchical linear modeling (HLM) was used to test the multilevel hypotheses. Organizational health culture had a significant effect on the planning effectiveness (β = .356, p organizational health culture on three dimensions of employee effectiveness were completely mediated by health behavior. The construct connections established in this multilevel model will help in

    2016-12-01

    The incidence of pediatric nephrolithiasis has risen over the past few decades leading to a growing public health burden. Children and adolescents represent a unique patient population secondary to their higher risks from radiation exposure as compared to adults, high risk of recurrence, and longer follow up time given their longer life expectancies. Ultrasound imaging is the first-line modality for diagnosing suspected nephrolithiasis in children. Although data is limited, the best evidence based medicine supports the use of alpha-blockers as first-line MET in children, especially when stones are small and in a more distal ureteral location. Surgical management of pediatric nephrolithiasis is similar to that in adults with ESWL and URS first-line for smaller stones and PCNL reserved for larger renal stone burden. Clinical effectiveness in minimizing risks in children and adolescents with nephrolithiasis centers around ED pathways that limit CT imaging, strict guidance to ALARA principles or use of US during surgical procedures, and education of both patients and families on the risks of repeat ionizing radiation exposures during follow up and acute colic events.

    Full Text Available Abstract Background We investigated the relation between hospital volume and outcome in patients with severe acute pancreatitis (SAP. The determination is important because patient outcome may be improved through volume-based selective referral. Methods In this cohort study, we analyzed 22,551 SAP patients in 2,208 hospital-years (between 2000 and 2009 from Taiwan’s National Health Insurance Research Database. Primary outcome was hospital mortality. Secondary outcomes were hospital length of stay and charges. Hospital SAP volume was measured both as categorical and as continuous variables (per one case increase each hospital-year. The effect was assessed using multivariable logistic regression models with generalized estimating equations accounting for hospital clustering effect. Adjusted covariates included patient and hospital characteristics (model 1, and additional treatment variables (model 2. Results Irrespective of the measurements, increasing hospital volume was associated with reduced risk of hospital mortality after adjusting the patient and hospital characteristics (adjusted odds ratio [OR] 0.995, 95% confidence interval [CI] 0.993-0.998 for per one case increase. The patients treated in the highest volume quartile (≥14 cases per hospital-year had 42% lower risk of hospital mortality than those in the lowest volume quartile (1 case per hospital-year after adjusting the patient and hospital characteristics (adjusted OR 0.58, 95% CI 0.40-0.83. However, an inverse relation between volume and hospital stay or hospital charges was observed only when the volume was analyzed as a categorical variable. After adjusting the treatment covariates, the volume effect on hospital mortality disappeared regardless of the volume measures. Conclusions These findings support the use of volume-based selective referral for patients with SAP and suggest that differences in levels or processes of care among hospitals may have contributed to the volume

    In the present study the authors evaluated therapy-related long-term adverse effects and physical activity in a cohort of long-term survivors of childhood acute lymphoblastic leukemia (ALL), diagnosed in their center between March 1991 and August 2000, treated according to the AIEOP (Associazione Italiana di Ematologia e Oncologia Pediatrica) ALL 91 or 95 study protocol and regularly seen in the authors' long-term follow-up unit. The authors analyzed the long-term sequelae of major body systems in this cohort of subjects and administered an "ad hoc" questionnaire concerning sport. The authors found that 70 patients out of 102 (68.5%) showed no late effects, 10% presented only instrumental or neuropsychological test abnormalities, and 21.5% had 1 or more clinical late sequelae. None of the evidenced late effects represented a contraindication to do physical activity. Sixty-one percent of survivors do physical activity, most of them regularly. Sixty-one percent of males and 18.5% of females (P < .005) do competitive sport (sports rates are similar to those of the general age-matched population). Nearly all subjects spontaneously choose to do sport and think physical exercise is an important and useful resource for their health. The authors conclude that the more recent therapy regimens for leukemia treatment, excluding bone marrow transplantation, do not seem to cause such late effects as to prevent survivors from doing sport. Therefore, in the care of ALL survivors, physical activity is not only not contraindicated, but should also be promoted as much as possible. The development of specific educational programs is warranted as part of the care of cancer survivors.

  17. Decitabine is more cost effective than cytarabine and daunorubicin in elderly acute myeloid leukemia patients

    2014-04-01

    Full Text Available Introduction: Decitabine is not approved in the United States (US for acute myeloid leukemia (AML because it did not improve overall survival compared with standard conventional induction treatment with cytarabine and daunorubicin (AD. We asked what would be the cost effectiveness of decitabine versus AD in AML patients older than 60 years of age. Methods: A semi-Markov model compiling survival and cost data was used based on survival probabilities from the literature. Data accounted for re-induction therapy with idarubicin, fludarabine, cytarabine and granulocyte colony-stimulating factor and consolidation therapy with high-dose cytarabine (HiDAC but not for stem cell transplantation. The assumption-based model considered a maximum of four cycles of HiDAC and continuing decitabine until loss of benefit. Results: Assuming 1,000 patients for each treatment arm in a semi-Markov model over one year time horizon, the quality-adjusted life year (QALY for AD vs. decitabine were 0.47 and 0.61. The percentage survival for AD and decitabine were 45.2% and 50.5%. Their costs were $168,863 and $108,084. The incremental cost-effectiveness ratio was -$60,779/0.14 = -$433,756 per QALY. By sensitivity analysis, decitabine was superior to AD in all parameters. Conclusion: Decitabine is a more cost-effective therapy for patients older than 60 years of age than AD. While cost effectiveness is certainly important, decitabine may be arguably considered for elderly newly diagnosed AML patients given the economic pressures in the US health system; however, this is not a criterion for drug approval.

    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.

  19. Acute and training effects of resistance exercise on heart rate variability.

    2016-05-01

    Heart rate variability (HRV) has been used as a non-invasive method to evaluate heart rate (HR) regulation by the parasympathetic and sympathetic divisions of the autonomic nervous system. In this review, we discuss the effect of resistance exercise both acutely and after training on HRV in healthy individuals and in those with diseases characterized by autonomic dysfunction, such as hypertension and fibromyalgia. HR recovery after exercise is influenced by parasympathetic reactivation and sympathetic recovery to resting levels. Therefore, examination of HRV in response to acute exercise yields valuable insight into autonomic cardiovascular modulation and possible underlying risk for disease. Acute resistance exercise has shown to decrease cardiac parasympathetic modulation more than aerobic exercise in young healthy adults suggesting an increased risk for cardiovascular dysfunction after resistance exercise. Resistance exercise training appears to have no effect on resting HRV in healthy young adults, while it may improve parasympathetic modulation in middle-aged adults with autonomic dysfunction. Acute resistance exercise appears to decrease parasympathetic activity regardless of age. This review examines the acute and chronic effects of resistance exercise on HRV in young and older adults. © 2014 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    2010-06-01

    Full Text Available Introduction: recent clinical trials found that high-dose statin therapy, compared with conventional-dose statin therapy, reduces the risk of cardiovascular events in patients with acute coronary syndromes (ACS and stable coronary artery disease (CAD. With the introduction of simvastatin and pravastatin generics and the next patent expiration of atorvastatin, projected for 2011 in Italy, it is natural to ask: what is the most cost-effective treatment for a rational use of resources?Aim: the aim of this study was to estimate the cost-effectiveness of high-dose atorvastatin versus conventional standard-dose statins based on the scenario of atovastatin price evolution.Methods: a cost-effectiveness analysis was conducted in the perspective of the Italian National Health Service over the 4.9 years time horizon. Clinical data were obtained from a pooled analyses of the 3 clinical trials that directly compared high-dose atorvastatin with conventional standard-dose statins in patients with either ACS or CAD. Hospitalizations were quantified based on the Italian National Health Service tariffs and drug costs according to the Italian National Therapeutic Formulary (2009. Assuming the cost of atorvastatin reduces in line with that observed for simvastatin when the patent expires, 3 scenarios were constructed: atorvastatin current price (scenario 1; 55% price discount (scenario 2; 65% price discount (scenario 3. Effects were measured in terms of primary composite endpoint (coronary death or any adverse cardiovascular event. All costs were discounted at 3% per annum. Sensitivity analyses were performed to assess the robustness of findings. Results: intensive therapy with atorvastatin provided a hospitalization cost saving of 245,519.36 € per 1,000 patients. Under the assumptions established for scenario 1 and scenario 2, the incremental cost-effectiveness of treatment with atorvastatin 80 mg was estimated to be 20,289.72 € and 917.05 € for patient free

    Airport is an extremely complex emission source of airborne pollutants that can have a significant impact on the environment. Indeed, several airborne chemicals emitted during airport activities may significantly get worse air quality and increase exposure level of both airport workers and general population living nearby the airports. In recent years airport traffic has increased and consequently several studies investigated the association between airport-related air pollution and occurrence of adverse health effects, particularly on respiratory system, in exposed workers and general population resident nearby. In this context, we carried out a critical evaluation of the studies that investigated this correlation in order to obtain a deeper knowledge of this issue and to identify the future research needs. Results show that the evidence of association between airport-related air pollution and health effects on workers and residents is still limited.

  3. Health Effects of Noise Exposure in Children.

    Stansfeld, Stephen; Clark, Charlotte

    2015-06-01

    Environmental noise exposure, such as road traffic noise and aircraft noise, is associated with a range of health outcomes in children. Children demonstrate annoyance responses to noise, and noise is also related to lower well-being and stress responses, such as increased levels of adrenaline and noradrenaline. Noise does not cause more serious mental health problems, but there is growing evidence for an association with increased hyperactivity symptoms. Studies also suggest that noise might cause changes in cardiovascular functioning, and there is some limited evidence for an effect on low birth weight. There is robust evidence for an effect of school noise exposure on children's cognitive skills such as reading and memory, as well as on standardised academic test scores. Environmental noise does not usually reach levels that are likely to affect children's hearing; however, increasing use of personal electronic devices may leave some children exposed to harmful levels of noise.

  4. Redistributive effects of Swedish health care finance.

    1998-01-01

    This paper investigates the redistributive effects of the Swedish health care financing system in 1980 and 1990 for four different financial sources: county council taxes, payroll taxes, direct payments and state grants. The redistributive effects are decomposed into vertical, horizontal and 'reranking' segments for each of the four financial sources. The data used are based on probability samples of the Swedish population, from the Level of Living Survey (LNU) from 1981 and 1991. The paper concludes that the Swedish health care financing system is weakly progressive, although direct payments are regressive. There is some horizontal inequity and 'reranking', which mainly comes from the county council taxes, since those tax rates vary for each county council. The implication is that, to some extent, people with equal incomes are treated unequally.

    Hormones level and lipid peroxidation processes under influence of acute alcohol intoxication are tested in testes and adrenals of rats. Ethanol marker effects--the rise of corticosterone biosynthesis and depression of testosterone concentration--were reproduced in the experiment. At the moment of maximal changes in steroid levels indices characterising lipid peroxidation didn't differ from the control. At the early stage of the experiment transient shifts in malonic dialdehyde and dienic conjugates levels were noted. The data obtained does not agree with the hypothesis of acute ethanol effects in testes and adrenals being mediated through the changes of lipid peroxidation rate.

    The bioelectric cardiac activity was studied in the experiments on white mice with an acute cerebral blood circulation disorder. It was found that he resulting EEG changes possess a specific character, with the sympathoadrenal system stimulation playing an important role in the acute cerebrocardiac syndrome development. The antioxidant-type agents such as emoxypine (50 mg/kg), mexidol (50 mg/kg), and cytochrome C (10 mg/kg) produce a significant cardioprotective effect in the test animals with experimental cerebral ischemia, which was comparable with the effect of propranolol (obsidane) (0.1 mg/kg).

    This paper reports the characteristics and local management of 826 acute wounds identified during an audit across all health care providers serving the population of Bradford, UK. Of the wounds encountered 303 were traumatic wounds and 237 primary closures with smaller numbers of other acute wound types. Of the 303 traumatic wounds 174 occurred in women (57.4%). Men predominated in the under 45s (65M:26F), this being largely accounted for by hand and finger trauma (n = 62) particularly in patients of working age (M32:F12). Women predominated in the over 65s (50M:130F), this being largely accounted for by lower limb traumatic wounds (M24:F91), the majority of these being in patients 65 and over (M14:F82). In this sub-group of 96 patients 25 had wounds of 6 weeks or longer duration, only 3 had undergone Doppler assessment and only 2 received compression bandaging. Typically these wounds were of recent origin and small in size (under 1 week and less than 5 cm2 in surface area) however exceptions occurred where 10 people had wounds over 25 cm2 in area while 3 wounds had been present for over 5 years. 101 (12.2%) of the encountered wounds were considered to be infected although the practice of wound swabbing in the presence of presumed infection seemed inadequate with 37.6% of all infected acute wounds not being swabbed while 97 non-infected wounds were swabbed. Where wounds were swabbed 4.5% were found to be MRSA positive. Across all acute wound types (with the sole exception of primary closures) antimicrobial wound dressings were the most prevalent form of dressing and covered 56 (55.4%) of all infected wounds.

    Acute alkalosis may directly affect PTH secretion. The effect of acute metabolic and respiratory alkalosis was studied in 20 dogs. PTH values were lower in the metabolic (5.6 +/- 0.8 pg/ml) and respiratory (1.8 +/- 0.6 pg/ml) alkalosis groups than in the control group (27 +/- 5 pg/ml). Acute alkalosis is an independent factor that decreases PTH values during normocalcemia and delays the PTH response to hypocalcemia. We recently showed that acute metabolic and respiratory acidosis stimulated PTH secretion. This study was designed to evaluate whether acute metabolic and respiratory alkalosis suppressed parathyroid hormone (PTH) secretion. Three groups of 10 dogs were studied: control, acute metabolic alkalosis, and acute respiratory alkalosis. Metabolic alkalosis was induced with an infusion of sodium bicarbonate and respiratory alkalosis by hyperventilation. Calcium chloride was infused to prevent alkalosis-induced hypocalcemia during the first 60 minutes. During the next 30 minutes, disodium EDTA was infused to induce hypocalcemia and to evaluate the PTH response to hypocalcemia. Because the infusion of sodium bicarbonate resulted in hypernatremia, the effect of hypernatremia was studied in an additional group that received hypertonic saline. After 60 minutes of a normocalcemic clamp, PTH values were less (p respiratory (1.8 +/- 0.6 pg/ml) alkalosis groups than in the control group (27 +/- 5 pg/ml); the respective blood pH values were 7.61 +/- 0.01, 7.59 +/- 0.02, and 7.39 +/- 0.02. The maximal PTH response to hypocalcemia was similar among the three groups. However, the maximal PTH response was observed after a decrease in ionized calcium of 0.20 mM in the control group but not until a decrease of 0.40 mM in the metabolic and respiratory alkalosis groups. In contrast to the metabolic alkalosis group, hypernatremia (157 +/- 2 mEq/liter) in the hypertonic saline group was associated with an increased PTH value (46 +/- 4 pg/ml). Finally, the half-life of intact PTH

    To examine the accuracy of the original Mortality Probability Admission Model III, ICU Outcomes Model/National Quality Forum modification of Mortality Probability Admission Model III, and Acute Physiology and Chronic Health Evaluation IVa models for comparing observed and risk-adjusted hospital mortality predictions. Retrospective paired analyses of day 1 hospital mortality predictions using three prognostic models. Fifty-five ICUs at 38 U.S. hospitals from January 2008 to December 2012. Among 174,001 intensive care admissions, 109,926 met model inclusion criteria and 55,304 had data for mortality prediction using all three models. None. We compared patient exclusions and the discrimination, calibration, and accuracy for each model. Acute Physiology and Chronic Health Evaluation IVa excluded 10.7% of all patients, ICU Outcomes Model/National Quality Forum 20.1%, and Mortality Probability Admission Model III 24.1%. Discrimination of Acute Physiology and Chronic Health Evaluation IVa was superior with area under receiver operating curve (0.88) compared with Mortality Probability Admission Model III (0.81) and ICU Outcomes Model/National Quality Forum (0.80). Acute Physiology and Chronic Health Evaluation IVa was better calibrated (lowest Hosmer-Lemeshow statistic). The accuracy of Acute Physiology and Chronic Health Evaluation IVa was superior (adjusted Brier score = 31.0%) to that for Mortality Probability Admission Model III (16.1%) and ICU Outcomes Model/National Quality Forum (17.8%). Compared with observed mortality, Acute Physiology and Chronic Health Evaluation IVa overpredicted mortality by 1.5% and Mortality Probability Admission Model III by 3.1%; ICU Outcomes Model/National Quality Forum underpredicted mortality by 1.2%. Calibration curves showed that Acute Physiology and Chronic Health Evaluation performed well over the entire risk range, unlike the Mortality Probability Admission Model and ICU Outcomes Model/National Quality Forum models.

    Trees remove air pollution by the interception of particulate matter on plant surfaces and the absorption of gaseous pollutants through the leaf stomata. However, the magnitude and value of the effects of trees and forests on air quality and human health across the United States remains unknown. Computer simulations with local environmental data reveal that trees and forests in the conterminous United States removed 17.4 million tonnes (t) of air pollution in 2010 (range: 9.0-23.2 million t), with human health effects valued at 6.8 billion U.S. dollars (range: $1.5-13.0 billion). This pollution removal equated to an average air quality improvement of less than one percent. Most of the pollution removal occurred in rural areas, while most of the health impacts and values were within urban areas. Health impacts included the avoidance of more than 850 incidences of human mortality and 670,000 incidences of acute respiratory symptoms.

    Treatment with intravenous streptokinase is known to restore blood flow to the ischaemic myocardium in patients with acute myocardial infarction. However, little is known about its effect on chest pain. In a retrospective cohort study, 76 patients treated with streptokinase were compared to 76...... patients not treated with streptokinase. All patients had acute myocardial infarction and less than 6 h of cardiac symptoms. Patients treated with streptokinase had a significantly lower need for nicomorphine (median 20 mg) than patients not treated with streptokinase (median 41 mg). Correspondingly......, the median duration (3.5 h) of pain was reduced significantly in patients treated with streptokinase compared to patients not treated (24 h). We conclude that intravenous streptokinase given in the acute phase of myocardial infarction is effective in reducing the duration of cardiac chest pain....

    Full Text Available Abstract Background The elevated serum and peritoneal cytokine concentrations responsible for the systemic response syndrome (SIRS and multiorgan failure in patients with severe acute pancreatitis lead to high morbidity and mortality rates. Prompted by reports underlining the importance of reducing circulating inflammatory mediators in severe acute pancreatitis, we designed this study to evaluate the efficiency of laparotomy followed by continuous perioperative peritoneal lavage combined with postoperative continuous venovenous diahemofiltration (CVVDH in managing critically ill patients refractory to intensive care therapy. As the major clinical outcome variables we measured morbidity, mortality and changes in the Acute Physiology and Chronic Health Evaluation (APACHE II score and cytokine concentrations in serum and peritoneal lavage fluid over time. Methods From a consecutive group of 23 patients hospitalized for acute pancreatitis, we studied 6 patients all with Apache II scores ≥19, who underwent emergency surgery for acute complications (5 for an abdominal compartment syndrome and 1 for septic shock followed by continuous perioperative peritoneal lavage and postoperative CVVDH. CVVDH was started within 12 hours after surgery and maintained for at least 72 hours, until the multiorgan dysfunction syndrome improved. Samples were collected from serum, peritoneal lavage fluid and CVVDH dialysate for cytokine assay. Apache II scores were measured daily and their association with cytokine levels was assessed. Results All six patients tolerated CVVDH well, and the procedure lasted a mean 6 days (range, 3-12. Five patients survived and one died of Acinetobacter infection after surgery (mortality rate 16.6%. The mean APACHE II score was ≥ 19 (range 19-22 before laparotomy and decreased significantly during peritoneal lavage and postoperative CVVDH (P = 0.013 by matched-pairs Students t-test. The decrease in cytokine concentrations in serum and

    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.

    Full Text Available Abstract Background Several methodological issues with non-randomized comparative clinical studies have been raised, one of which is whether the methods used can adequately identify uncertainties that evolve dynamically with time in real-world systems. The objective of this study is to compare the effectiveness of different combinations of Traditional Chinese Medicine (TCM treatments and combinations of TCM and Western medicine interventions in patients with acute ischemic stroke (AIS by using Markov decision process (MDP theory. MDP theory appears to be a promising new method for use in comparative effectiveness research. Methods The electronic health records (EHR of patients with AIS hospitalized at the 2nd Affiliated Hospital of Guangzhou University of Chinese Medicine between May 2005 and July 2008 were collected. Each record was portioned into two "state-action-reward" stages divided by three time points: the first, third, and last day of hospital stay. We used the well-developed optimality technique in MDP theory with the finite horizon criterion to make the dynamic comparison of different treatment combinations. Results A total of 1504 records with a primary diagnosis of AIS were identified. Only states with more than 10 (including 10 patients' information were included, which gave 960 records to be enrolled in the MDP model. Optimal combinations were obtained for 30 types of patient condition. Conclusion MDP theory makes it possible to dynamically compare the effectiveness of different combinations of treatments. However, the optimal interventions obtained by the MDP theory here require further validation in clinical practice. Further exploratory studies with MDP theory in other areas in which complex interventions are common would be worthwhile.

    A test meal (300 mg casein, 600 mg sucrose, 100 mg corn oil, tracer dose of 9.10(3)H oleic acid) was given to fasting adult rats with intestinal lymph fistulas. One group received an acute oral dose of ethanol (3.2 g/kg body weight) simultaneously with the test meal. Controls received 2.5 ml of water instead of ethanol. Ingestion of ethanol temporarily delayed the removal of lipid radioactivity from the stomachs. More than 25% of radioactivity fed remained 8 hr after feeding whereas with control rats less than 10% of lipid radioactivity fed remained 6 hr after feeding. In controls and ethanol-treated rats, the amounts of exogenous lipids in the intestinal lumen and mucosa were low and similar enough. Quantities of endogenous and exogenous lipids found in the lymph collected during 24 hr after feeding were similar in the two groups, but the fat absorption peak was found after 6 hr in alcoholic rats and before 6 hr in controls. This delay was probably due to the retention of lipids in the stomach. More of the exogenous lipid was always transported by small particles moving in the region of alpha1 globulins in cellulose acetate electrophoresis than by larger particles remaining at the origin. This proportion was enhanced in the ethanol-treated animals. The larger fat particles were richer in endogenous fatty acids in alcohol-treated rats than in controls.

    One hundred and eighty-two SD rats were randomly divided into the normal control group, fast operating group and food-intake operating group. The experimental model of acute pancreatitis (AP) in rats was established by injecting 5 % sodium taurocholate into the pancreatic duct of rat according to Aho's method. The sandostatin was used for positive contrast. The concentrations of serum amylase, calcium, C reaction protein (CRP) and interleukin-6 (IL-6) were assayed respectively at different time points. The pathological sections were observed. Each operating group contained 10 rats. The mortality of the operating groups was observed during the 24 h. The serum amylase level in the AP rats was reduced after receiving vagotomy (VG, P<0.05). Although the serum calcium level in most groups was decreased, the reduction in the group with VG plus sandostatin was not obvious (P>0.05). The increase of CRP and IL-6 was not obvious after VG (P>0.05). The change of mortality was not significant (P>0.05). The pathological sections showed that the AP pathological change was mild after VG. The disease condition of food-intake operating group was more serious than that of fast operating group. It was suggested that VG had some influence on the prognosis of AP in rats.

    Full Text Available The aim of the present study was to investigate the effects of an acute physical activity intervention including cognitive engagement on executive functions and on cortisol level in young elementary school children. Half of the 104 participating children (6 to 8 years old attended a 20-minute sport sequence, which included cognitively engaging and playful forms of physical activity. The other half was assigned to a resting control condition. Individual differences in children`s updating, inhibition, and shifting performance as well as salivary cortisol were assessed before (pre-test, immediately after (post-test, and 40 minutes after (follow-up the intervention or control condition respectively. Results revealed a significantly stronger improvement in inhibition in the experimental group compared to the control group, while it appeared that acute physical activity had no specific effect on updating and shifting. The intervention effect on inhibition levelled out 40 minutes after physical activity. Salivary cortisol increased significantly more in the experimental compared to the control group between post-test and follow-up and results support partly the assumed inverted U-shaped relationship between cortisol level and cognitive performance. In conclusion, results indicate that acute physical activity including cognitive engagement may have immediate positive effects on inhibition, but not necessarily on updating and shifting in elementary school children. This positive effect may partly be explained trough cortisol elevation after acute physical activity.

    Full Text Available The aim of this study was to evaluate the protective effect of different doses of diphenhydramine against acute toxicosis with Levamisole. The Mechanism of levamisole induced acute toxicity and that of protective effect of diphenhydramine against Levamisole toxicosis also examined on the level of cholinesterase (ChE activity. Subcutanous injection of 100mg/kg levamisole in male mice with induced cholinergic over stimulation and death in 100% of animals. The Toxicosis was not related to the significantly decreased in plasma, red blood cells and brain ChE activity. Injection low dose of diphenhydramin 2.5mg/kg S.C. 15 min before levamisole produced protective effect against acute toxicity with levamisole. Significantly decreased the severity of toxicosis and increased survival rates to 100%. Diphenhydramine at low dose alone or with acute dose of levamisole did not Produced Significantly inhibition in ChE activity.The data suggested that the toxic effect of Levamisole was not related to inhibition of ChE. The low dose of diphenhydramine protected mice from Levamisole toxicity. The antidoatal effect of diphenhydramine not at the level of protection from ChE inhibition. There was no adverse interaction between two drugs.

    Introduction Acute levodopa challenge may be performed to predict levodopa chronic responsiveness. The aim of the study was to investigate frequency of side effects during the acute levodopa challenge in PD and atypical parkinsonisms. Methods We enrolled 34 de novo PD patients and 29 patients affected by atypical parkinsonisms (Multiple System Atrophy, MSA, n = 10; Progressive Supranuclear Palsy, PSP, n = 12 and Corticobasal Degeneration, CBD, n = 7) who underwent an acute levodopa challenge. Side effects occurring during test were recorded. Results Side effects were more frequent among atypical parkinsonisms as unique group when compared to PD patients (64.3% versus 23.5%; p-value 0.002) with an adjusted OR of 4.36 (95%CI 1.40–13.5). Each atypical parkinsonisms showed almost double occurrence of side effects (MSA 90%, PSP 41.7% and CBD 57%). Conclusions Side effects during acute levodopa challenge may be frequent in atypical parkinsonisms. This information could be useful in order to better prepare the patient for the test. Furthermore, it could represent a useful cue in differential diagnosis with PD.
