    Cadmium (Cd), a by-product of zinc production, is one of the most toxic elements to which man can be exposed at work or in the environment. Once absorbed, Cd is efficiently retained in the human body, in which it accumulates throughout life. Cd is primarily toxic to the kidney, especially to the proximal tubular cells, the main site of accumulation. Cd can also cause bone demineralization, either through direct bone damage or indirectly as a result of renal dysfunction. In the industry, excessive exposures to airborne Cd may impair lung function and increase the risk of lung cancer. All these effects have been described in populations with relatively high exposures to Cd in the industrial or in heavily polluted environments. Recent studies, however, suggest that the chronic low environmental exposure to Cd now prevailing in industrialized countries can adversely affect the kidneys and bones of the general population. These studies show consistent associations between various renal and bone biomarkers and the urinary excretion of Cd used to assess Cd body burden. The public health impact of these findings are still unknown. Further research is needed to ascertain that these associations are truly causal and not secondary to parallel changes in Cd metabolism and in the bone or kidney function occurring because of ageing or diseases unrelated to Cd exposure.

    The use of wood stoves has increased greatly in the past decade, causing concern in many communities about the health effects of wood smoke. Wood smoke is known to contain such compounds as carbon monoxide, nitrogen oxides, sulfur oxides, aldehydes, polycyclic aromatic hydrocarbons, and fine respirable particulate matter. All of these have been shown to cause deleterious physiologic responses in laboratory studies in humans. Some compounds found in wood smoke--benzo(a)pyrene and formaldehyde--are possible human carcinogens. Fine particulate matter has been associated with decreased pulmonary function in children and with increased chronic lung disease in Nepal, where exposure to very high amounts of wood smoke occurs in residences. Wood smoke fumes, taken from both outdoor and indoor samples, have shown mutagenic activity in short-term bioassay tests. Because of the potential health effects of wood smoke, exposure to this source of air pollution should be minimal.29 references.

    The effects of poor lighting and glare on public safety are well-known, as are the harmful environmental effects on various species and the environment in general. What is less well-known is the potential harmful medical effects of excessive poor nighttime lighting. A significant body of research has been developed over the last few years regarding this problem. One of the most significant effects is the startling increased risk for breast cancer by excessive exposure to nighttime lighting. The mechanism is felt to be by disruption of the circadian rhythm and suppression of melatonin production from the pineal gland. Melatonin has an anticancer effect that is lost when its production is disrupted. I am in the process of developing a monograph that will summarize this important body of research, to be presented and endorsed by the American Medical Association, and its Council of Science and Public health. This paper is a brief overall summary of this little known potential harmful effect of poor and excessive nighttime lighting.

    Noise pollution from road traffic in residential areas is a growing environmental problem. New approaches to turn the negative trend are needed. The programme “Soundscape Support to Health” will achieve new knowledge about the adverse health effects of noise pollution on humans and will investigate the link between well-being and health and perceived soundscapes for optimizing the acoustic soundscapes in urban residential areas. This paper will briefly present the programme and presents preliminary results from the first study of how various adverse health effects are related to individual noise exposures among individuals in residential areas with and without access to a quiet side of the dwelling.

  7. Categories of adverse health effects from indoor air pollution

    International Nuclear Information System (INIS)

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

    This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys that were randomly allocated at birth across three rearing conditions: mother rearing, peer rearing, and surrogate peer rearing. We show that the lack of a secure attachment relationship in the early years engendered by adverse rearing conditions has detrimental long-term effects on health that are not compensated for by a normal social environment later in life.

MATERIAL AND METHOD: The population of this descriptive- cross-sectional study is 15-49 age, married women who recruited in the number 15 health-center region. The sample consisted of 183 women who were selected with systematic sampling method. A questionnaire designed with researcher based on literature which was 30 questions include fertility characteristics, VD practice and adverse health effects was used to collect data. The data were collected by the researcher with home visiting between April-May 2005. Descriptive statistics and X² test were used to analysis data. RESULTS: The mean age of women in the study group is 33.5±7.86, 87. 4 % has primary school education, 68.3 % middle income, 54.6 % practice VD. The mean year of VD practice is 12.9±8.8 and 65.1 % douche at least once a week. The reasons of the women’s VD practices are religious practice (45.4 %, cleaning (41.5% and preventing pregnancy(13.1% and, 68.9 % of women don’t know harmfull efects of VD. There was no difference between history of sterility, extopic pregnancy, abortus, low birth weigh, symptoms of genito-urinary infection and its frequency and VD in the X² test. There was a difference between contraceptive method used and VD. CONCLUSION: Sterility, extopic pregnancy, abortus, low birth weigh, symptoms of genito-urinary infection and its frequency were not related to VD. We suggest that the women have been educated about adverse health effects of VD and analytic researches may be planned for causal relationship between adverse health effects and VD.

    Androgen deprivation therapy (ADT) plays a central role in the management of men with locally advanced, recurrent, and metastatic prostate cancer. Because most men diagnosed with prostate cancer will die of something other than their cancer, treatment-related adverse effects are highly relevant to their long-term health. Benefits of ADT in each clinical setting must be weighed against ADT-related adverse effects. ADT is detrimental to several metabolic end points and to bone health. ADT has b...

    2014-10-01

    In an effort to address climate change, governments have pursued policies that seek to reduce greenhouse gases. Alternative energy, including wind power, has been proposed by some as the preferred approach. Few would debate the need to reduce air pollution, but the means of achieving this reduction is important not only for efficiency but also for health protection. The topic of adverse health effects in the environs of industrial wind turbines (AHE/IWT) has proven to be controversial and can present physicians with challenges regarding the management of an exposure to IWT. Rural physicians in particular must be aware of the possibility of people presenting to their practices with a variety of sometimes confusing complaints. An earlier version of the diagnostic criteria for AHE/IWT was published in August 2011. A revised case definition and a model for a study to establish a confirmed diagnosis is proposed.

    The Development of Countermeasures for Space Radiation Induced Adverse Health Effects Ann R. Kennedy Department of Radiation Oncology, University of Pennsylvania School of Medicine, 195 John Morgan Building, 3620 Hamilton Walk, Philadelphia, PA, United States 19104-6072 The development of countermeasures for radiation induced adverse health effects is a lengthy process, particularly when the countermeasure/drug has not yet been evaluated in human trials. One example of a drug developed from the bench to the clinic is the soybean-derived Bowman-Birk inhibitor (BBI), which has been developed as a countermeasure for radiation induced cancer. It was originally identified as a compound/drug that could prevent the radiation induced carcinogenic process in an in vitro assay system in 1975. The first observation that BBI could inhibit carcinogenesis in animals was in 1985. BBI received Investigational New Drug (IND) Status with the U.S. Food and Drug Administration (FDA) in 1992 (after several years of negotiation with the FDA about the potential IND status of the drug), and human trials began at that time. Phase I, II and III human trials utilizing BBI have been performed under several INDs with the FDA, and an ongoing Phase III trial will be ending in the very near future. Thus, the drug has been in development for 35 years at this point, and it is still not a prescription drug on the market which is available for human use. A somewhat less time-consuming process is to evaluate compounds that are on the GRAS (Generally Recognized as Safe) list. These compounds would include some over-the-counter medications, such as antioxidant vitamins utilized in human trials at the levels for which Recommended Dietary Allowances (RDAs) have been established. To determine whether GRAS substances are able to have beneficial effects on radiation induced adverse health effects, it is still likely to be a lengthy process involving many years to potentially decades of human trial work.

    Full Text Available Introduction: Radar workers are exposed to pulsed high frequency electromagnetic fields. In this study, health effects of these radiations in personnel who routinely work with radar systems are investigated. Materials and Methods: The 28-item General Health Questionnaire was used as a self-administered tool for assessment of general mental health and mental distress. One hundred workers occupationally exposed to radar radiations (14-18 GHz participated in the study. Visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. To assess the short-term memory, Wechsler Memory Scale-III test was performed. Results: Twenty to 39% of the radar workers reported different problems such as needing a good tonic, feeling run down and out of sorts, headache, tightness or pressure in the head, insomnia, getting edgy and bad-tempered. Furthermore, 47% of the radar workers reported feeling under strain. In response to this question that if they have been able to enjoy their normal day-to-day activities, 31% responded "less than usual". It was also shown that work experience had significant relationships with reaction time and short-term memory indices i.e., forward digit span, reverse digit span, word recognition and paired words. Conclusion: To the best of our knowledge, this is the first study to show that occupational exposure to radar microwave radiation leads to changes in somatic symptoms, anxiety and insomnia, social dysfunction, and severe depression. Altogether these results indicate that occupational exposure to radar microwave radiations may be linked to some adverse health effects.

  4. Adverse health effects due to arsenic exposure: Modification by dietary supplementation of jaggery in mice

    International Nuclear Information System (INIS)

    Populations of villages of eastern India and Bangladesh and many other parts of the world are exposed to arsenic mainly through drinking water. Due to non-availability of safe drinking water they are compelled to depend on arsenic-contaminated water. Generally, poverty level is high in those areas and situation is compounded by the lack of proper nutrition. The hypothesis that the deleterious health effects of arsenic can be prevented by modification of dietary factors with the availability of an affordable and indigenous functional food jaggery (sugarcane juice) has been tested in the present study. Jaggery contains polyphenols, vitamin C, carotene and other biologically active components. Arsenic as sodium-m-arsenite at low (0.05 ppm) and high (5 ppm) doses was orally administered to Swiss male albino mice, alone and in combination with jaggery feeding (250 mg/mice), consecutively for 180 days. The serum levels of total antioxidant, glutathione peroxidase and glutathione reductase were substantially reduced in arsenic-exposed groups, while supplementation of jaggery enhanced their levels in combined treatment groups. The serum levels of interleukin-1β, interleukin-6 and TNF-α were significantly increased in arsenic-exposed groups, while in the arsenic-exposed and jaggery supplemented groups their levels were normal. The comet assay in bone marrow cells showed the genotoxic effects of arsenic, whereas combination with jaggery feeding lessened the DNA damage. Histopathologically, the lung of arsenic-exposed mice showed the necrosis and degenerative changes in bronchiolar epithelium with emphysema and thickening of alveolar septa which was effectively antagonized by jaggery feeding. These results demonstrate that jaggery, a natural functional food, effectively antagonizes many of the adverse effects of arsenic.

    silica (Permissible Exposure Limit [PEL] 0.05 mg/m3) but more toxic than the nuisance dust titanium dioxide (TiO2 [PEL 5.0 mg/m3]). A PEL for episodic exposure to airborne lunar dust during a six-month stay on the lunar surface was established, in consultation with an independent, extramural panel of expert pulmonary toxicologists, at 0.3 mg/m3. The PEL provided for lunar dust is limited to the conditions and exposure specified therefore additional research remains to be accomplished with lunar dust to further address the issues of activation, address other areas of more unique lunar geology (Glotch et al., 2010; Greenhagen et al., 2010), examine potential toxicological effects of inhaled or ingested dust upon other organ systems, such cardiovascular, nervous systems, and examine effects of acute exposure to massive doses of dust such as may occur during off-nominal situations. Work to support the establishment of PELs for Martian dust and dusts of asteroids remains to be accomplished. The literature that describes health effects of exposure to toxic terrestrial dusts provides substantial basis for concern that prolonged exposure to respirable celestial dust could be detrimental to human health. Celestial bodies where a substantial portion of the dust is in the respirable range or where the dusts have large reactive surface areas or contain transition metals or volatile organics, represent greater risks of adverse effects from exposure to the dust. It is possible that in addition to adverse effects to the respiratory system, inhalation and ingestion of celestial dusts could pose risks to other systems

    Our research on adverse effects of lead exposures on physical and neurobehavioral health of children aged 6-12 years in 4 villages, labeled as K, M, L, and X, in rural China, was reported in this article. Lead in blood (PbB), urine (PbU), hairs (PbH), and nails (PbN) were measured by graphite furnace atomic absorption spectrometry. Abbreviated Symptom Questionnaire of Conner's instruments and Revised Raven's Standard Progressive Matrices were applied to evaluate childhood attention deficit/hyperactivity disorders (ADHD) and intelligences. Geometric means (SD) of PbB, PbU, PbH and PbN concentrations were 71.2 μg/L (1.56), 11.7 μg/g (1.75), 12.5 μg/g (2.82), and 25.3 μg/g (2.79), respectively. 54 (17.0%) children had PbB levels of ≥ 100 μg/L. Boys, the 6-10 years old, and living in village K were 2.11, 2.48, and 9.16 times, respectively, more likely to be poisoned by lead than girls, aged 11-12 years, and residing in X. 18 (5.7%) and 37 (11.7%) subjects had ADHD and mental retardations, respectively. Inverse relationships between intelligences and natural log transformed PbU and PbH levels were observed with respective odds ratios (95%CI) of 1.79 (1.00-3.22) and 1.46 (1.06-2.03) or 1.28 (1.04-1.58) and 1.73 (1.18-2.52) by binary or ordinal logistic regression modeling. ADHD prevalence was different by gender and age of subjects. PbU, PbH, and PbN related to PbB positively with respective correlation coefficients of 0.530, 0.477, and 0.181. Receiver operating characteristic (ROC) curves of the three measurements reveled areas under curves (AUCs) being 0.829, 0.758, and 0.687, respectively. In conclusion, children had moderate levels of lead exposures in this rural area. Intelligence declines were associated with internal lead levels among children. ROC analysis suggests PbU an internal lead indicator close to PbB.

Inverse relationships between intelligences and natural log transformed PbU and PbH levels were observed with respective odds ratios (95%CI) of 1.79 (1.00-3.22) and 1.46 (1.06-2.03) or 1.28 (1.04-1.58) and 1.73 (1.18-2.52) by binary or ordinal logistic regression modeling. ADHD prevalence was different by gender and age of subjects. PbU, PbH, and PbN related to PbB positively with respective correlation coefficients of 0.530, 0.477, and 0.181. Receiver operating characteristic (ROC) curves of the three measurements reveled areas under curves (AUCs) being 0.829, 0.758, and 0.687, respectively. In conclusion, children had moderate levels of lead exposures in this rural area. Intelligence declines were associated with internal lead levels among children. ROC analysis suggests PbU an internal lead indicator close to PbB.

  15. Agricultural sources of contaminants of emerging concern and adverse health effects on freshwater fish

    Science.gov (United States)

    Tillitt, Donald E.; Buxton, Herbert T.

    2011-01-01

    Agricultural contaminants of emerging concern (CECs) are generally thought of as certain classes of chemicals associated with animal feeding and production facilities. Veterinary pharmaceuticals used in animal food production systems represent one of the largest groups of CECs. In our review, we discuss the extensive increase in use of antibiotics in animal feeding operations (AFOs) around the world. AFOs are a major consumer of antibiotics and other veterinary pharmaceuticals and over the past decade there has been growing information on the occurrence, release, and fate of CECs from animal food production operations, including the application of pharmaceutical-containing manure to agricultural fields and releases from waste lagoons. Concentrations of CECs in surface and ground water in proximity to AFOs correspond to their presence in the AFO wastes. In many cases, the environmental concentrations of agriculturally-derived CECs are below toxicity thresholds. Hormones and hormone replacement compounds are a notable exception, where chemical concentrations near AFOs can exceed concentrations known to cause adverse effects on endocrine-related functions in fish. In addition, some agricultural pesticides, once thought to be safe to non-target organisms, have demonstrated endocrine-related effects that may pose threats to fish populations in agricultural regions. That is, we have pesticides with emerging concerns, thus, the concern is emerging and not necessarily the chemical. In this light, one must consider certain agricultural pesticides to be included in the list of CECs. Even though agricultural pesticides are routinely evaluated in regulatory testing schemes which have been used for decades, the potential hazards of some pesticides have only recently been emerging. Emerging concerns of pesticides in fish include interference with hormone signaling pathways; additive (or more than additive) effects from pesticide mixtures; and adverse population-level effects at

  16. Piezoelectric properties of quartz and cristobalite airborne particulates as a cause of adverse health effects

    Science.gov (United States)

    Williamson, B. J.; Pastiroff, S.; Cressey, G.

    Inhalation of quartz and cristobalite dusts is commonly linked with health effects although the mechanisms involved are poorly understood. Grinding of these piezoelectric silica polymorphs produces particulates with transient piezoelectric charges. This is likely to cause vigorous reaction with atmospheric gases and, through interaction with surface charges and 'dangling bonds', may lead to the formation of highly deleterious ozonide, superoxide and hydroxyl radicals. It is hoped that this study will encourage experimental work to quantify piezoelectric effects in silica dusts and to develop a method for their neutralisation during cutting and grinding processes.

    2012-06-01

    High doses of synthetic antioxidative vitamins: A, E, C and β-carotene are often used on long-term basis in numerous preventive and therapeutic medical applications. Instead of expected health effects, the use of those vitamins may however lead to cases of hypervitaminosis and even to intoxication. The article points out main principles of safety which are to be observed during supplementation with antioxidative vitamins. Toxic effects resulting from erroneous administration of high doses of those substances on organs and systems of the organism are also discussed. Attention is drawn to interactions of antioxidative vitamins with concomitantly used drugs, as well as intensification of adverse effects caused by various exogenous chemical factors. Moreover, the article presents the evaluation of supplementation with these vitamins, which was performed in large studies. PMID:22528540

    2016-09-01

    First impressions based on practitioner appearance often form the basis for preliminary assumptions regarding trust, confidence, and competence, especially in situations where patients or family members do not have an established relationship with the physician. Given their growing prevalence, we strove to further investigate whether visible tattoos or piercings on a medical provider affects a patient's perception of the provider's capabilities and their trust in the care that would be provided. A survey using photographs of simulated practitioners was administered to 314 participants split between rural and urban locations. Study volunteers rated tattooed practitioners with lower confidence ratings when compared with nontattooed practitioners and reported greater degrees of discomfort with greater degrees of facial piercing. We concluded that these factors adversely affect the clinical confidence ratings of practitioners, regardless of the gender, age group, or location of participants. PMID:26603585

    Full Text Available Background: Studies have revealed a powerful relationship between adverse childhood experiences (ACEs and physical and mental health in adulthood. Literature documents the conversion of traumatic emotional experiences in childhood into organic disease later in life. Objective: The aim was to estimate the effect of childhood experiences on the physical health of adults in Baghdad city. Subjects and Methods: A cross-sectional study was conducted from January 2013 to January 2014. The study sample was drawn from Baghdad city. Multistage sampling techniques were used in choosing 13 primary health care centers and eight colleges of three universities in Baghdad. In addition, teachers of seven primary schools and two secondary schools were chosen by a convenient method. Childhood experiences were measured by applying a modified standardized ACEs-International Questionnaire form and with questions for bonding to family and parental monitoring. Physical health assessment was measured by a modified questionnaire derived from Health Appraisal Questionnaire of Centers for Disease Control and Prevention. The questionnaire includes questions on cerebrovascular diseases, diabetes mellitus, tumor, respiratory and gastrointestinal diseases. Results: Logistic regression model showed that a higher level of bonding to family (fourth quartile is expected to reduce the risk of chronic physical diseases by almost the half (odds ratio = 0.57 and exposure to a high level of household dysfunction and abuse (fourth quartile is expected to increase the risk of chronic physical diseases by 81%. Conclusion: Childhood experiences play a major role in the determination of health outcomes in adulthood, and early prevention of ACEs. Encouraging strong family bonding can promote physical health in later life.

    Bernhardt, J H

    2005-01-01

    This review supplies a survey of the three physical influences, i. e. UV radiation, high-frequency electromagnetic fields of radio telephone systems and other wireless radio applications as well as low-frequency fields of electric power supply. The exposure to UV radiation must be considered to be by far the highest health risk. The annual rate of about 2000 deaths from skin cancer in Germany, mainly caused by extensive exposure to solar UV radiation, demands protective measures. Teaching reasonable behaviour is the supreme issue. Recommended protective measures in the order of their effectiveness are protection by adaptation of behaviour, by clothes, sun hats and sunglasses as well as by sun creams. Children are the most important target group. With regard to UV tanning appliances it is recommended not to use artificial UV radiation for cosmetic purposes because of the related health risks. For the assessment of health impairments caused by exposure to electromagnetic fields, direct field reactions due to induced electric body currents, reactions on the surface of the body or heating effects should be separated from indirect field reactions (e. g. electric shocks and burns) due to contact currents or interference with electronic body aids and implants. Risk assessment has led to recommendations of threshold values which-in agreement with international research results-exclude all impairments of health caused by direct field reactions scientifically proven to date. Contrary to public concerns, which are mostly related to base transmitters of radio telephone systems, exposure due to handheld radio telephones (cellular phones) should rather be considered from the viewpoint of precautionary health protection, since it is more likely that their use can lead to high exposure of the user. Due to the protective measures provided so far and observance of the threshold values based on scientific results, exposures do not lead to health impairments-not even in children

    2009-01-01

    Full Text Available Problem statements: Fumonisin was a mycotoxin produced mainly by fungi belonging to the genus Fusarium in various foods and feeds. They occurred worldwide and were found predominantly in corn and in corn-based animal feeds and also can be found in other crops. Contamination of food and feed with fumonisins has been implicated in and associated with a number of diseases in both livestock as well as human beings. Approach: A review was done on the effect of fumonisins on animal and human and detoxification method for the prevention. ScienceDirect, Scopus, PubMed, Google and Yahoo were used in the preparation of this review. Results: This review clarified that the major forms of fumonisins found in food were the B series, fumonisin B1, B2 and B3. Fumonisin B1 (FB1 was the most common and the most thoroughly studied. FB1 caused toxicities in animals including Equine Leukoencephalomalacia (ELEM, Porcine Pulmonary Edema (PPE in pigs and nephrotoxic, hepatotoxic and hepatocarcinogenic in rats. Furthermore, FB1 had been implicated to be associated with high rates of human esophageal cancer. In addition to their natural occurrence in corn-based animal feeds and in home-grown corn used for food, fumonisins were frequently found in commercial corn-based foods. Methods for prevention and detoxification for fumonisins included prevention of plants contamination at the field level and harvest and post-harvest control of fumonisins. Furthermore, the diseases occurred in livestock will pose the additional economic losses in livestock farmers. Conclusion: Due to economic losses engendered by fumonisin, several strategies for detoxifying and preventing contaminated foods and feeds had been described in the literature including physical and biological process. However these methods still in demonstrated. Awareness of fumonisin-related animal diseases, contamination of fumonisin in foods and feeds and adherence to guidance recommendation in prevention methods were

    Full Text Available Background: Existence or non-existence of adverse selection in insurance market is one of the important cases that have always been considered by insurers. Adverse selection is one of the consequences of asymmetric information. Theory of adverse selection states that high-risk individuals demand the insurance service more than low risk individuals do.Methods: The presence of adverse selection in Irans supplementary health insurance market is tested in this paper. The study group consists of 420 practitioner individuals aged 20 to 59. We estimate two logistic regression models in order to determine the effect of individual's characteristics on decision to purchase health insurance coverage and loss occurrence. Using the correlation between claim occurrence and decision to purchase health insurance, the adverse selection problem in Iranian supplementary health insurance market is examined.Results: Individuals with higher level of education and income level purchase less supplementary health insurance and make fewer claims than others make and there is positive correlation between claim occurrence and decision to purchase supplementary health insurance.Conclusion: Our findings prove the evidence of the presence of adverse selection in Iranian supplementary health insurance market.

    2016-05-01

    Phenytoin is an established drug in the treatment of acute repetitive seizures and status epilepticus. One of its main advantages over benzodiazepines is the less sedative effect. However, the possibility of cardiovascular adverse effects with the intravenous use of phenytoin cause a reluctance to its usage, and this has lead to a search for safer anticonvulsant drugs. In this study, we aimed to review the studies which evaluated the safety of phenytoin with respect to cardiovascular adverse effects. The original clinical trials and case reports listed in PUBMED in English language between the years of 1946-2014 were evaluated. As the key words, "phenytoin, diphenylhydantoin, epilepsy, seizure, cardiac toxicity, asystole, arrhythmia, respiratory arrest, hypotension, death" were used. Thirty-two clinical trials and ten case reports were identified. In the case reports, a rapid infusion rate (>50 mg/min) of phenytoin appeared as the major cause of increased mortality. In contrast, no serious cardiovascular adverse effects leading to death were met in the clinical trials which applied the recommended infusion rate and dosages. An infusion rate of 50 mg/min was reported to be safe for young patients. For old patients and patients with a cardiovascular co-morbidity, a slower infusion rate was recommended with a careful follow-up of heart rhythm and blood pressure. No cardiovascular adverse effect was reported in oral phenytoin overdoses except one case with a very high serum phenytoin level and hypoalbuminemia. Phenytoin is an effective and well tolerated drug in the treatment of epilepsy. Intravenous phenytoin is safe when given at recommended infusion rates and doses. PMID:26645393

    The aim of this study was to review original scientific articles describing the relationship between atmospheric pollution and damage to human health. We also aimed to determine which of these studies mentioned public policy issues. Original articles relating to atmospheric pollution and human health published between 1995 and 2009 were retrieved from the PubMed database and analyzed. This study included only articles dealing with atmospheric pollutants resulting primarily from vehicle emissions. Three researchers were involved in the final selection of the studies, and the chosen articles were approved by at least two of the three researchers. Of the 84 non-Brazilian studies analyzed, 80 showed an association between atmospheric pollution and adverse effects on human health. Moreover, 66 showed evidence of adverse effects on human health, even at levels below the permitted emission standards. Three studies mentioned public policies aimed at changing emission standards. Similarly, the 29 selected Brazilian studies reported adverse associations with human health, and 27 showed evidence of adverse effects even at levels below the legally permitted emission standards. Of these studies, 16 mentioned public policies aimed at changing emission standards. Based on the Brazilian and non-Brazilian scientific studies that have been conducted, it can be concluded that, even under conditions that are compliant with Brazilian air quality standards, the concentration of atmospheric pollutants in Brazil can negatively affect human health. However, as little discussion of this topic has been generated, this finding demonstrates the need to incorporate epidemiological evidence into decisions regarding legal regulations and to discuss the public policy implications in epidemiological studies.

    Electroconvulsive therapy (ECT) is an effective treatment commonly used for depression and other major psychiatric disorders. We discuss potential adverse effects (AEs) associated with ECT and strategies for their prevention and management. Common acute AEs include headache, nausea, myalgia, and confusion; these are self-limiting and are managed symptomatically. Serious but uncommon AEs include cardiovascular, pulmonary, and cerebrovascular events; these may be minimized with screening for risk factors and by physiologic monitoring. Although most cognitive AEs of ECT are short-lasting, troublesome retrograde amnesia may rarely persist. Modifications of and improvements in treatment techniques minimize cognitive and other AEs.

  15. Childhood adversity and adult health: Evaluating intervening mechanisms.

    Science.gov (United States)

    Turner, R Jay; Thomas, Courtney S; Brown, Tyson H

    2016-05-01

    Substantial evidence has accumulated supporting a causal link between childhood adversity and risk for poor health years and even decades later. One interpretation of this evidence is that this linkage arises largely or exclusively from a process of biological embedding that is not modifiable by subsequent social context or experience - implying childhood as perhaps the only point at which intervention efforts are likely to be effective. This paper considers the extent to which this long-term association arises from intervening differences in social context and/or environmental experiences - a finding that would suggest that post-childhood prevention efforts may also be effective. Based on the argument that the selected research definition of adult health status may have implications for the early adversity-adult health linkage, we use a representative community sample of black and white adults (N = 1252) to evaluate this relationship across three health indices: doctor diagnosed illnesses, self-rated health, and allostatic load. Results generally indicate that observed relationships between childhood adversity and dimensions of adult health status were totally or almost totally accounted for by variations in adult socioeconomic position (SEP) and adult stress exposure. One exception is the childhood SEP-allostatic load association, for which a statistically significant relationship remained in the context of adult stress and SEP. This lone finding supports a conclusion that the impact of childhood adversity is not always redeemable by subsequent experience. However, in general, analyses suggest the likely utility of interventions beyond childhood aimed at reducing exposure to social stress and improving social and economic standing. Whatever the effects on adult health that derive from biological embedding, they appear to be primarily indirect effects through adult social context and exposure. PMID:27030896

  17. Health-related quality of life in childhood epilepsy: Moving beyond 'seizure control with minimal adverse effects'

    Directory of Open Access Journals (Sweden)

    Rosenbaum Peter

    2003-08-01

    Full Text Available Abstract Childhood epilepsy is one of the most important and prevalent neurological conditions in the developing years. Persons with childhood onset epilepsy are at a high risk for poor psychosocial outcomes, even without experiencing co-morbidities. The goal of management of children with epilepsy should be to enable the child and the family to lead a life as free as possible from the medical and psychosocial complications of epilepsy. This comprehensive care needs to go beyond simply trying to control seizures with minimal adverse drug reactions. Seizure frequency and severity is only one important outcome variable. Other factors such as social, psychological, behavioural, educational, and cultural dimensions of their lives affect children with epilepsy, their families and their close social networks. A number of epilepsy-specific health-related quality of life (HRQL scales for children have been developed with the aim to include and measure accurately the impact and burden of epilepsy. Their target populations, details of the origin of the items, and psychometric properties vary significantly. Their strengths and weaknesses will be identified more clearly through their continued use in the clinical setting and in research studies. Only a few studies to date have utilized these or generic HRQL measures to assess the HRQL of specific populations with epilepsy. Future research needs to develop theory driven models of HRQL and identify measurable factors that have important correlations with outcomes. Since biomedical variables like seizure frequency and severity have only moderate correlations with HRQL, other independent factors including the child's resilience, co-morbid conditions, parental well-being, family factors and societal/cultural variables may play a major role. We also need to learn what encompasses comprehensive patient care, define the goals of management and evaluate the impact of different interventions. Future studies need to

    Health insurance markets face two forms of adverse selection problems. On the demand side, adverse selection leads to plan price distortions and inefficient sorting of consumers across health plans. On the supply side, adverse selection creates incentives for plans to inefficiently distort benefits to attract profitable enrollees. These problems can be addressed by features of health plan payment systems such as reinsurance, risk adjustment, and premium categories. In this paper, we develop H...

This paper reviews reports of U-shaped outcome associations with vitamin D status for evidence of underlying pathophysiological processes, or of confounding, finding that some U-shaped associations appear to be biologically meaningful, but that many could well reflect confounding by factors such as lifestyle, or hypovitaminosis D-related disease onset being masked by self-supplementation that was begun too late to correct developing health problems but before baseline vitamin D status assessment. However, the various U-shaped associations for allergic reactions may be due to vitamin D modulation of the phenotype of the immune response, shifting the Th1-Th2 balance toward Th2 formation. For prostate cancer, there seems to be little effect of 25(OH)D concentration on incidence; however, there is an inverse correlation between 25(OH)D concentration and mortality rates. Future observational studies, and randomized controlled trial data analyses, should include adjustment for data collected on prior long-term vitamin D supplementation and solar UVB exposure, as well as other potential confounders.

    Objective The study tested the performance of adverse effects search filters when searching for safety information on medical devices, procedures, and diagnostic tests in MEDLINE and Embase. Methods The sensitivity of 3 filters was determined using a sample of 631 references from 131 rapid reviews related to the safety of health technologies. The references were divided into 2 sets by type of intervention: drugs and nondrug health technologies. Keyword and indexing analysis were performed on references from the nondrug testing set that 1 or more of the filters did not retrieve. Results For all 3 filters, sensitivity was lower for nondrug health technologies (ranging from 53%–87%) than for drugs (88%–93%) in both databases. When tested on the nondrug health technologies set, sensitivity was lower in Embase (ranging from 53%–81%) than in MEDLINE (67%–87%) for all filters. Of the nondrug records that 1 or more of the filters missed, 39% of the missed MEDLINE records and 18% of the missed Embase records did not contain any indexing terms related to adverse events. Analyzing the titles and abstracts of nondrug records that were missed by any 1 filter, the most commonly used keywords related to adverse effects were: risk, complications, mortality, contamination, hemorrhage, and failure. Conclusions In this study, adverse effects filters were less effective at finding information about the safety of medical devices, procedures, and tests compared to information about the safety of drugs.

    Oral squamous cell carcinoma (OSCC) is a world health problem with approximately 50% of patients having a 5-year survival rate. A change in the demographics of the disease is now being recognised, particularly in Europe, where it is increasingly being seen in young males. While a variety of risk factors are important in OSCC, it is tobacco that plays a central part in the pathogenesis of the disease. Narghile is an old form of tobacco use but in the past decade, there has been a resurgence in this form of smoking. The practice is particularly common in young males and females from the Middle East but with the advent of immigration and globalisation, its use is becoming more widespread. It is now not uncommon to see narghile smoking in western countries such as the UK and USA. Studies describing the oral effects of narghile are unfortunately scarce. While adverse effects such as periodontal bone loss and dry socket have been described, its association with OSCC cannot be excluded. Variation in the type of narghile, the type of tobacco and the presence of co-factors such as cigarette smoking may all influence clinical outcome. In the present study, the practice of narghile smoking is reviewed in terms of its effect on health, particularly oral health. The association of narghile smoking and adverse effects on the orofacial region will be outlined, namely, periodontal disease, potentially malignant lesions and oral cancer. PMID:19521371

    2011-05-01

    The experience of poverty during childhood is a potent predictor of a variety of adverse health outcomes during middle and late adulthood. Children who live in poverty are more likely as adults than their peers to develop and die earlier from a range of diseases. These effects are especially strong for cardiovascular disease and type II diabetes. Most disturbingly, these effects appear in large part to be biologically embedded such that later improved life circumstances have only a modest ameliorative effect. Considering these findings and the relatively high rates of child poverty in nations such as Canada, UK, and USA, those concerned with improving the health of citizens should focus their attention on advocating for public policy that will reduce the incidence of child poverty.

    2016-04-01

    Hydrofluorosis in humans and domestic animals is a worldwide health problem and caused by a prolonged period of fluoride exposure through drinking of fluoride contaminated water. But in recent years, due to rapid industrialization in India, diverse serious health problems among industrial workers and residents and domestic animals living in the industrial areas due to fluoride pollution are on the rise. A number of coal-burning and industrial activities such as power-generating stations, welding operations and the manufacturing or production of steel, iron, aluminum, zinc, phosphorus, chemical fertilizers, bricks, glass, plastic, cement, and hydrofluoric acid are generally discharging fluoride in both gaseous and particulate/dust forms into surrounding environments which create a industrial fluoride pollution and are an important cause of occupational exposure to fluoride in several countries including India. An industrial emitted fluoride contaminates not only surrounding soil, air, and water but also vegetation, crops and many other biotic communities on which man and animals are generally dependants for food. Long- time of inhalation or ingestion of industrial fluoride also causes serious health problems in the forms of industrial and neighborhood fluorosis. In India, whatever research works conducted so far on the chronic industrial fluoride intoxication or poisoning (industrial and neighborhood fluorosis) in man and various species of domestic animals due to a prolonged period of industrial fluoride exposure or pollution (contamination) are critically reviewed in the present communication. Simultaneously, we are also focused the various bio-indicators and bio-markers for chronic industrial fluoride intoxication or pollution. PMID:26903127

    The purpose of this report is to present a review of the medical uses, efficacy, and adverse effects of the three approved cannabis-based medications and ingested marijuana. A literature review was conducted utilizing key search terms: dronabinol, nabilone, nabiximols, cannabis, marijuana, smoke, efficacy, toxicity, cancer, multiple sclerosis, nausea, vomiting, appetite, pain, glaucoma, and side effects. Abstracts of the included literature were reviewed, analyzed, and organized to identify the strength of evidence in medical use, efficacy, and adverse effects of the approved cannabis-based medications and medical marijuana. A total of 68 abstracts were included for review. Dronabinol's (Marinol) most common medical uses include weight gain, chemotherapy-induced nausea and vomiting (CINV), and neuropathic pain. Nabiximol's (Sativex) most common medical uses include spasticity in multiple sclerosis (MS) and neuropathic pain. Nabilone's (Cesamet) most common medical uses include CINV and neuropathic pain. Smoked marijuana's most common medical uses include neuropathic pain and glaucoma. Orally ingested marijuana's most common medical uses include improving sleep, reducing neuropathic pain, and seizure control in MS. In general, all of these agents share similar medical uses. The reported adverse effects of the three cannabis-based medications and marijuana show a major trend in central nervous system (CNS)-related adverse effects along with cardiovascular and respiratory related adverse effects. Marijuana shares similar medical uses with the approved cannabis-based medications dronabinol (Marinol), nabiximols (Sativex), and nabilone (Cesamet), but the efficacy of marijuana for these medical uses has not been fully determined due to limited and conflicting literature. Medical marijuana also has similar adverse effects as the FDA-approved cannabis-based medications mainly consisting of CNS related adverse effects but also including cardiovascular and respiratory

    Full Text Available Abstract Background The H1N1 influenza pandemic had garnered a large amount of attention. Currently, the most effective preventive measure available is the H1N1 vaccine. We aimed to assess the willingness of our study participants to receive the H1N1 vaccination prior to the annual Hajj season. If any participant declined, we investigated the reasons for vaccine rejection. Findings We conducted a prospective cohort study of National Guard employees during the 1430 (2009 Hajj season. A survey was used as the primary method for data collection. Participants were vaccinated one to two weeks prior to their trip to Mona, and any side effects reported at the time of injection and three weeks post vaccination were recorded. There were 100 male and 26 female participants in the study. In total, 66.7% (n = 84 of the participants were health care workers (HCWs and 33.3% (n = 42 were non-health care workers (non-HCWs. Less than half of the respondents (46.8%, n = 59 accepted the vaccination. The vaccination acceptance rate was higher among non-HCWs, at a rate of 71.4% (n = 30; HCWs only accepted at a rate of 34.5% (n = 29 (OR 1.103, 95% CI [0.488-2.496]. The most common reason for vaccine refusal was the impression that the disease was not fatal (25.4%, n = 32. Finally, all participants reported pain at the injection site and 18.3% (n = 11 reported swelling. All other side effects were reported in less than 15% of the participants. Conclusions Despite fears of the new H1N1 vaccine, there was a reasonable rate of vaccine acceptance among our study participants. Early health education may increase the rate of acceptance of the H1N1 vaccine. Furthermore, additional research is needed on long-term adverse effects of the H1N1 vaccine.

    Full Text Available Biological rhythm of sleeping is a natural disparity in an organism corresponding to and in reply to cyclic environmental changes, such as daylight hours and hours of darkness or elevated and low down flow. There is some evidence, based upon epidemiological studies as well as studies upon smaller groups of subjects, that individuals who work during the night and sleep during the daytime show cognitive impairment at work, have poorer and fragmented daytime sleep, and have increased risks of developing a wide range of social, psychological, physiological and medical impairments and disorders. Circadian rhythms are one of the most important effective factors on the physiological and physical performances of humans and disturbing this normal rhythm leads to different groups of diseases. The majority of investigations in biological rhythm demeanor vary noticeably in regards to the exact type of disease, population and protocols of sampling over the other outcomes or issues. We conducted a systematic review of [Science Direct, Pubmed, Scopus] to identify influence of different kinds of diseases among shift workers in response to abnormal rhythm of sleeping. The results of this review indicate that abnormal patterns of sleeping can lead to immunological issues, hypertension, metabolic syndrome, insomnia, cardiovascular disease, obesity and depression. It is vital for subsequent investigations to find a way to reduce negative effects (such as decreased amount of works’ time and altered diet without side effects to help them.

  14. Adverse Effects of Wheat Gluten.

    Koning, Frits

    2015-01-01

    Man began to consume cereals approximately 10,000 years ago when hunter-gatherers settled in the fertile golden crescent in the Middle East. Gluten has been an integral part of the Western type of diet ever since, and wheat consumption is also common in the Middle East, parts of India and China as well as Australia and Africa. In fact, the food supply in the world heavily depends on the availability of cereal-based food products, with wheat being one of the largest crops in the world. Part of this is due to the unique properties of wheat gluten, which has a high nutritional value and is crucial for the preparation of high-quality dough. In the last 10 years, however, wheat and gluten have received much negative attention. Many believe that it is inherently bad for our health and try to avoid consumption of gluten-containing cereals; a gluten-low lifestyle so to speak. This is fueled by a series of popular publications like Wheat Belly; Lose the Wheat, Lose the Weight, and Find Your Path Back to Health. However, in reality, there is only one condition where gluten is definitively the culprit: celiac disease (CD), affecting approximately 1% of the population in the Western world. Here, I describe the complexity of the cereals from which gluten is derived, the special properties of gluten which make it so widely used in the food industry, the basis for its toxicity in CD patients and the potential for the development of safe gluten and alternatives to the gluten-free diet.

    (131)I, when released in a radiological or nuclear accident as happened recently in Fukushima, Japan, may cause thyroid cancer as a long-term consequence. Iodine thyroid blocking (ITB) is known to reduce the risk of developing thyroid cancer. Potential adverse effects of ITB have not been systematically investigated so far. This article summarises the results of a review on adverse effects of ITB based on a systematic literature search in scientific medical databases. A meta-analysis was not performed as identified studies displayed major heterogeneity. The search resulted in 14 articles relevant to the topic, reporting mostly on surveys, ecological and intervention studies. Only one study from Poland focused on effects (both desired and adverse) of an ITB intervention following the Chernobyl accident. All other studies reported on iodine administration in a different context. Overall, the studies did not reveal severe adverse reactions to potassium iodide in the general public. Since ITB is a protective measure only applied in very specific circumstances, scientifically sound studies of adverse effects are scarce and consequently the evidence base is weak. The assessment of adverse effects of ITB relies on indirect evidence from related areas. This study may contribute to ongoing developments in pharmacoepidemiology aiming to better quantify adverse effects of medications and health care interventions including ITB. PMID:22021061

    2015-01-01

    This study examined associations between adverse childhood family experiences and adult physical health using data from 52,250 US adults aged 18–64 from the 2009–2012 Behavioral Risk Factor Surveillance System (BRFSS). We found that experiencing childhood physical, verbal, or sexual abuse, witnessing parental domestic violence, experiencing parental divorce, and living with someone who was depressed, abused drugs or alcohol, or who had been incarcerated were associated with one or more of the following health outcomes: self-rated health, functional limitations, diabetes, and heart attack. Adult socioeconomic status and poor mental health and health behaviors significantly mediated several of these associations. The results of this study highlight the importance of family-based adverse childhood experiences on adult health outcomes and suggest that adult SES and stress-related coping behaviors may be crucial links between trauma in the childhood home and adult health.

  18. The NAS Perchlorate Review: Adverse Effects?

    Energy Technology Data Exchange (ETDEWEB)

    Johnston, Richard B.; Corley, Richard; Cowan, Linda; Utiger, Robert D.

    2005-11-01

    To the editor: Drs. Ginsberg and Rice argue that the reference dose for perchlorate of 0.0007 mg/kg per day recommended by the National Academies’ Committee to Assess the Health Implications of Perchlorate Ingestion is not adequately protective. As members of the committee, we disagree. Ginsberg and Rice base their conclusion on three points. The first involves the designation of the point of departure as a NOEL (no-observed-effect level) versus a LOAEL (lowest-observed-adverse- effect level). The committee chose as its point of departure a dose of perchlorate (0.007 mg/kg per day) that when given for 14 days to 7 normal subjects did not cause a significant decrease in the group mean thyroid iodide uptake (Greer et al. 2002). Accordingly, the committee considered it a NOEL. Ginsberg and Rice focus on the fact that only 7 subjects were given that dose, and they 1seem to say that attention should be paid only to the results in those subjects in whom there was a 1fall in thyroid iodide uptake, and that the results in those in whom there was no fall or an increase should be ignored. They consider the dose to be a LOAEL because of the fall in uptake in those few subjects. It is important to note that a statistically significant decrease of, for example, 5% or even 10%, would not be biologically important and, more important, would not be sustained. For example, in another study (Braverman et al. 2004), administration of 0.04 mg/kg per day to normal subjects for 6 months had no effect on thyroid iodide uptake when measured at 3 and 6 months, and no effect on serum thyroid hormone or thyrotropin concentrations measured monthly (inspection of Figure 5A in the paper by Greer et al. suggests that this dose would inhibit thyroid iodide uptake by about 25% if measured at 2 weeks). The second issue involves database uncertainty. In clinical studies, perchlorate has been administered prospectively to 68 normal subjects for 2 weeks to 6 months. In one study (Brabant et al. 1992

  20. Psychiatric Adverse Effects of Dermatological Drugs

    Directory of Open Access Journals (Sweden)

    2010-07-01

    Full Text Available Dermatological drugs, mostly corticosteroids and isotretinoin, cause different psychiatric adverse effects. During steroid therapy, a wide range of psychiatric conditions, from minor clinical symptoms like insomnia and anxiety to serious psychiatric syndromes like psychosis and delirium might be seen. In medical literature, a causal connection is usually suggested between “isotretinoin”, which is used for treatment of acne vulgaris and depression and suicide attempts. However, there are no statistically significant double-blind randomized studies that support this connection. Clinicians must know patient’s psychiatric history before using any dermatological treatment known as causing psychiatric adverse effects, and psychiatric consultation should be established whenever necessary.

  1. Cardiac adverse effects of nicotine replacement therapy.

    Science.gov (United States)

    2015-12-01

    Smoking markedly increases the risk of cardiovascular disease. Nicotine replacement therapy is available to assist in smoking cessation. To assess the cardiac adverse effects of nicotine replacement therapy, we conducted a review of the literature using the standard Prescrire methodology. A meta-analysis of 21 randomised, placebo-controlled trials published in early 2014 included a total of 11 647 patients, including 828 patients at high risk of cardiovascular events and 187 patients with acute coronary disorders. It showed that nicotine replacement therapy was associated with an increased risk of cardiac disorders, particularly palpitations, which are a known adverse effect of smoking. Among patients at high cardiovascular risk, 1.2% experienced a serious cardiovascular event, with no statistically significant difference versus placebo. Bupropion and varenicline both have serious adverse effects and have been less extensively evaluated in patients at high cardiovascular risk. In practice, when a drug is needed to assist in smoking cessation, nicotine appears to be a reasonable choice. Nicotine replacement therapy exposes patients to a risk of palpitations but rarely to serious cardiac disorders, even in individuals with a cardiovascular history. In addition, these adverse effects are better documented than those of bupropion and varenidine in such patients. Nonetheless, the cardiac effects of nicotine call for prudent use of nicotine replacement therapy: the minimum effective dose should be sought, and the goal should be total nicotine withdrawal.

    2011-01-01

    Full Text Available Background: Bevacizumab a recombinant humanized monoclonal antibody was approved in 2004 by US FDA for metastatic colorectal cancer. It is reported to cause potentially serious toxicities including severe hypertension, proteinuria, and congestive heart failure. Aim: To correlate adverse event tetany with the use of bevacizumab. Materials and Methods : World Health Organization′s Uppsala Monitoring Centre, Sweden, for reporting of adverse drug reactions from all over the world, identified 7 cases with tetany-related symptoms to bevacizumab from four different countries. These 7 patients reported to UMC database developed adverse events described as musculoskeletal stiffness (1, muscle spasm (1, muscle cramps (1, lock jaw or jaw stiffness (4, and hypertonia (1, with hypocalcaemia. Results: After detailed study of the possible mechanism of actions of bevacizumab and factors causing tetany, it is proposed that there is a possibility of tetany by bevacizumab, which may occur by interfering with calcium metabolism. Resorption of bone through osteoclasts by affecting VEGF may interfere with calcium metabolism. Another possibility of tetany may be due to associated hypomagnesaemia, hypokalemia, or hyponatremia. Conclusions: Tetany should be considered as a one of the signs. Patient on bevacizumab should carefully watch for tetany-related symptoms and calcium and magnesium levels for their safety.

  5. Excessive folic acid intake and relation to adverse health outcome.

    Selhub, Jacob; Rosenberg, Irwin H

    2016-07-01

    The recent increase in the intake of folic acid by the general public through fortified foods and supplements, has raised safety concern based on early reports of adverse health outcome in elderly with low B12 status who took high doses of folic acid. These safety concerns are contrary to the 2015 WHO statement that "high folic acid intake has not reliably been shown to be associated with negative healeffects". In the folic acid post-fortification era, we have shown that in elderly participants in NHANES 1999-2002, high plasma folate level is associated with exacerbation of both clinical (anemia and cognitive impairment) and biochemical (high MMA and high Hcy plasma levels) signs of vitamin B12 deficiency. Adverse clinical outcomes in association with high folate intake were also seen among elderly with low plasma B12 levels from the Framingham Original Cohort and in a study from Australia which combined three elderly cohorts. Relation between high folate and adverse biochemical outcomes were also seen in the Sacramento Area Latino Study on Aging (High Hcy, high MMA and lower TC2) and at an outpatient clinic at Yale University where high folate is associated with higher MMA in the elderly but not in the young. Potential detrimental effects of high folic acid intake may not be limited to the elderly nor to those with B12 deficiency. A study from India linked maternal high RBC folate to increased insulin resistance in offspring. Our study suggested that excessive folic acid intake is associated with lower natural killer cells activity in elderly women. In a recent study we found that the risk for unilateral retinoblastoma in offspring is 4 fold higher in women that are homozygotes for the 19 bp deletion in the DHFR gene and took folic acid supplement during pregnancy. In the elderly this polymorphism is associated with lower memory and executive scores, both being significantly worse in those with high plasma folate. These and other data strongly imply that

    Despite medical advances, childhood health and well-being have not been broadly achieved due to rising chronic diseases and conditions related to child poverty. Family and neighborhood living conditions can have lasting consequences for health, with community adversity affecting health outcomes in significant part through stress response and increased allostatic load. Exposure to this "toxic stress" influences gene expression and brain development with direct and indirect negative consequences for health. Ensuring healthy child development requires improving conditions in distressed, high-poverty neighborhoods by reducing children's exposure to neighborhood stressors and supporting good family and caregiver functioning. The community development industry invests more than $200 billion annually in low-income neighborhoods, with the goal of improving living conditions for residents. The most impactful investments have transformed neighborhoods by integrating across sectors to address both the built environment and the social and service environment. By addressing many facets of the social determinants of health at once, these efforts suggest substantial results for children, but health outcomes generally have not been considered or evaluated. Increased partnership between the health sector and community development can bring health outcomes explicitly into focus for community development investments, help optimize intervention strategies for health, and provide natural experiments to build the evidence base for holistic interventions for disadvantaged children. The problems and potential solutions are beyond the scope of practicing pediatricians, but the community development sector stands ready to engage in shared efforts to improve the health and development of our most at-risk children.

    Nearly two thirds of patients with cancer will undergo radiation therapy as part of their treatment plan. Given the increased use of radiation therapy and the growing number of cancer survivors, family physicians will increasingly care for patients experiencing adverse effects of radiation. Selective serotonin reuptake inhibitors have been shown to significantly improve symptoms of depression in patients undergoing chemotherapy, although they have little effect on cancer-related fatigue. Radiation dermatitis is treated with topical steroids and emollient creams. Skin washing with a mild, unscented soap is acceptable. Cardiovascular disease is a well-established adverse effect in patients receiving radiation therapy, although there are no consensus recommendations for cardiovascular screening in this population. Radiation pneumonitis is treated with oral prednisone and pentoxifylline. Radiation esophagitis is treated with dietary modification, proton pump inhibitors, promotility agents, and viscous lidocaine. Radiation-induced emesis is ameliorated with 5-hydroxytryptamine3 receptor antagonists and steroids. Symptomatic treatments for chronic radiation cystitis include anticholinergic agents and phenazopyridine. Sexual dysfunction from radiation therapy includes erectile dysfunction and vaginal stenosis, which are treated with phosphodiesterase type 5 inhibitors and vaginal dilators, respectively.

    Full Text Available Obesity and overeating are among the most prevalent health concerns worldwide and individuals are increasingly using performance and image-enhancing drugs (PIEDs as an easy and fast way to control their weight. Among these, herbal weight-loss products (HWLPs often attract users due to their health claims, assumed safety, easy availability, affordable price, extensive marketing, and the perceived lack of need for professional oversight. Reports suggest that certain HWLPs may lead to onset or exacerbation of psychiatric disturbances. Here we review the available evidence on psychiatric adverse effects of HWLPs due to their intrinsic toxicity and potential for interaction with psychiatric medications.

    Life-threatening and benign drug reactions occur frequently in the skin, affecting 8 % of the general population and 2-3 % of all hospitalized patients, emphasizing the need for physicians to effectively recognize and manage patients with drug-induced eruptions. Neurologic medications represent a vast array of drug classes with cutaneous side effects. Approximately 7 % of the United States (US) adult population is affected by adult-onset neurological disorders, reflecting a large number of patients on neurologic drug therapies. This review elucidates the cutaneous reactions associated with medications approved by the US Food and Drug Administration (FDA) to treat the following neurologic pathologies: Alzheimer disease, amyotrophic lateral sclerosis, epilepsy, Huntington disease, migraine, multiple sclerosis, Parkinson disease, and pseudobulbar affect. A search of the literature was performed using the specific FDA-approved drug or drug classes in combination with the terms 'dermatologic,' 'cutaneous,' 'skin,' or 'rash.' Both PubMed and the Cochrane Database of Systematic Reviews were utilized, with side effects ranging from those cited in randomized controlled trials to case reports. It behooves neurologists, dermatologists, and primary care physicians to be aware of the recorded cutaneous adverse reactions and their severity for proper management and potential need to withdraw the offending medication.

    The beneficial and adverse effects of some chemopreventive agents, such as Vitamins A, C, E, beta-carotene, indole-3-carbinol, capsaicin, garlic, and aloe are reviewed. Two large randomized trials with a lung cancer endpoint, the Alpha-Tocopherol, Beta-Carotene (ATBC) Prevention Study and the Beta-Carotene and Retinol Efficacy Trial (CARET), suggested that antioxidants might be harmful in smokers. However, the results of the Linxian study and of the ATBC or the CARET studies were significantly different in this respect, and therefore, the relationship between antioxidant and carcinogenesis remains open to debate. Indole-3-carbinol has cancer promoting activities in the colon, thyroid, pancreas, and liver, whereas capsaicin alters the metabolism of chemical carcinogens and may promote carcinogenesis at high doses. Organosulfur compounds and selenium from garlic have no or a little enhancing effect on cancer promotion stage. Information upon chemopreventive mechanisms that inhibit carcinogenesis is imperfect, although the causes and natures of certain human cancers are known. Therefore, definitive preventive guidelines should be carefully offered for various types of tumors, which properly consider ethnic variations, and the efficacies and the safety of chemopreventive agents.

    IgG is widely used for patients with immune deficiencies and in a broad range of autoimmune and inflammatory disorders. Up to 40% of intravenous infusions of IgG may be associated with adverse effects (AEs), which are mostly uncomfortable or unpleasant but often are not serious. The most common infusion-related AE is headache. More serious reactions, including true anaphylaxis and anaphylactoid reactions, occur less frequently. Most reactions are related to the rate of infusion and can be prevented or treated just by slowing the infusion rate. Medications such as nonsteroidal anti-inflammatory drugs, antihistamines, or corticosteroids also may be helpful in preventing or treating these common AEs. IgA deficiency with the potential of IgG or IgE antibodies against IgA increases the risk of some AEs but should not be viewed as a contraindication if IgG therapy is needed. Potentially serious AEs include renal dysfunction and/or failure, thromboembolic events, and acute hemolysis. These events usually are multifactorial, related to combinations of constituents in the IgG product as well as risk factors for the recipient. Awareness of these factors should allow minimization of the risks and consequences of these AEs. Subcutaneous IgG is absorbed more slowly into the circulation and has a lower incidence of AEs, but awareness and diligence are necessary whenever IgG is administered. PMID:24565701

    In response to the attacks on Sept 11, 2001 (9/11), and the related security concerns, the USA and its coalition partners began a war in Afghanistan and subsequently invaded Iraq. The wars caused many deaths of non-combatant civilians, further damaged the health-supporting infrastructure and the environment (already adversely affected by previous wars), forced many people to migrate, led to violations of human rights, and diverted resources away from important health needs. After 9/11 and the anthrax outbreak shortly afterwards, the USA and other countries have improved emergency preparedness and response capabilities, but these actions have often diverted attention and resources from more urgent health issues. The documentation and dissemination of information about the adverse health effects of these wars and about the diversion of resources could help to mitigate these consequences and prevent their recurrence.

    Results from medical examinations conducted in 2012 of workers who were engaged in radiation work in 2012 as a result of the 2011 Fukushima Daiichi Nuclear Power Plant (NPP) accident showed that the prevalence of abnormal findings was 4.21%, 3.23 points higher than the 0.98% that was found prior to the accident in the jurisdiction area of the labor inspection office which holds jurisdiction over the NPP. The Ministry of Health, Labour and Welfare (MHLW) concluded that the 2010 and 2012 data cannot be easily compared because 70% of the enterprises within the jurisdiction of the office that reported the 2012 results were different from those that did so in 2010. In addition, although the radiation workers' estimated average dose weighted by number of workers was 3.66 times higher than decontamination workers' dose, the prevalence among radiation workers was only 1.14 times higher than that among decontamination workers. Based on the results of the medical examinations, however, the MHLW decided to implement an epidemiological study on the health effects of radiation exposure on all emergency workers. This article explains key issues of the basic design of the study recommended by the expert meeting established in the MHLW and also identifies challenges that could not be resolved and thus required further consideration by the study researchers. The major issues included: (a) study methods and target group; (b) evaluation of cumulative doses; (c) health effects (end points); (d) control of confounding factors; and (e) study implementation framework. Identified key challenges that required further deliberation were: (a) preventing arbitrary partisan analysis; (b) ensuring a high participation rate; (c) inquiry about the medical radiation doses; and (d) the preparedness of new analytical technology. The study team formulated and implemented the pilot study in 2014 and started the full-scale study in April 2015 with funding from a research grant from the MHLW. PMID

    Despite the high prevalence of performance-enhancing drug (PED) use, media attention has focused almost entirely on PED use by elite athletes to illicitly gain a competitive advantage in sports, and not on the health risks of PEDs. There is a widespread misperception that PED use is safe or that adverse effects are manageable. In reality, the vast majority of PED users are not athletes but rather nonathlete weightlifters, and the adverse health effects of PED use are greatly underappreciated. This scientific statement synthesizes available information on the medical consequences of PED use, identifies gaps in knowledge, and aims to focus the attention of the medical community and policymakers on PED use as an important public health problem. PED users frequently consume highly supraphysiologic doses of PEDs, combine them with other PEDs and/or other classical drugs of abuse, and display additional associated risk factors. PED use has been linked to an increased risk of death and a wide variety of cardiovascular, psychiatric, metabolic, endocrine, neurologic, infectious, hepatic, renal, and musculoskeletal disorders. Because randomized trials cannot ethically duplicate the large doses of PEDs and the many factors associated with PED use, we need observational studies to collect valid outcome data on the health risks associated with PEDs. In addition, we need studies regarding the prevalence of PED use, the mechanisms by which PEDs exert their adverse health effects, and the interactive effects of PEDs with sports injuries and other high-risk behaviors. We also need randomized trials to assess therapeutic interventions for treating the adverse effects of PEDs, such as the anabolic-androgen steroid withdrawal syndrome. Finally, we need to raise public awareness of the serious health consequences of PEDs. PMID:24423981

    Full Text Available Abstract Background Studies of toxicity and unintended side effects can lead to improved drug safety and efficacy. One promising form of study comes from molecular systems biology in the form of "systems pharmacology". Systems pharmacology combines data from clinical observation and molecular biology. This approach is new, however, and there are few examples of how it can practically predict adverse reactions (ADRs from an experimental drug with acceptable accuracy. Results We have developed a new and practical computational framework to accurately predict ADRs of trial drugs. We combine clinical observation data with drug target data, protein-protein interaction (PPI networks, and gene ontology (GO annotations. We use cardiotoxicity, one of the major causes for drug withdrawals, as a case study to demonstrate the power of the framework. Our results show that an in silico model built on this framework can achieve a satisfactory cardiotoxicity ADR prediction performance (median AUC = 0.771, Accuracy = 0.675, Sensitivity = 0.632, and Specificity = 0.789. Our results also demonstrate the significance of incorporating prior knowledge, including gene networks and gene annotations, to improve future ADR assessments. Conclusions Biomolecular network and gene annotation information can significantly improve the predictive accuracy of ADR of drugs under development. The use of PPI networks can increase prediction specificity and the use of GO annotations can increase prediction sensitivity. Using cardiotoxicity as an example, we are able to further identify cardiotoxicity-related proteins among drug target expanding PPI networks. The systems pharmacology approach that we developed in this study can be generally applicable to all future developmental drug ADR assessments and predictions.

    Full Text Available Due to the important role of thyroid disorders on reproductive health of the women of childbearing age, pregnancy outcome, fetal health, and neurodevelopment of the infant, providing comprehensive assessment of the treatments used for preventing hyperthyroidism and hypothyroidism seems to be essential. Therefore, evaluating the efficacy of different treatments of the thyroid disorders would be beneficial in better managing and controlling the disease during pregnancy. Hypothyroidism (a deficiency of thyroid hormone is a common thyroid disorder, which might increase the incidence rate of miscarriage, pre-eclampsia, placental abruption, and preterm delivery. Hyperthyroidism, which is not a common disorder during the pregnancy not only leads to similar adverse effects as hypothyroidism but also can result in stillbirth and intrauterine growth restriction. Levothyroxine is the preferred treatment of hypothyroidism and the only drug therapy recommended for treating hyperthyroidism during pregnancy. In this study, we aimed to briefly review the adverse effects of hyperthyroidism and hypothyroidism during pregnancy and review the effects of recent suggested treatments for controlling thyroid disorders on pregnancy outcomes.

Design – Analytical survey. Subjects – A case study using a recently published systematic review of the effectiveness and adverse effects of seven new anti-epileptic drugs. Setting – MEDLINE and EMBASE searches performed by researchers at the Centre for Reviews and Dissemination and the UK Cochrane Centre Search Filters Design Group at the University of York, UK. Methods – Five key approaches to searching were defined. The first approach used either text words or controlled vocabulary to search for specific adverse effects. The second used subheadings or qualifiers either attached to drug names found in the controlled vocabulary (approach 2a or ‘floating’ without drug names (approach 2b. The third approach used text words as synonyms for the phrase ‘adverse effects.’ The fourth used controlled indexing terms for adverse effects. The fifth and final approach used two published search strategies incorporating study design (Badgett et al., Loke et al.. These five approaches were used to search for studies of the adverse effects of seven new anti‐epileptic drugs. 5,011 unique papers were retrieved. Of these, 236 were judged potentially relevant and 225 full text articles were obtained. The inclusion criteria from a previously published systematic review (Wilby et al. were applied to the papers, and 79 met the criteria. Five papers were added to the set after being identified from reference lists, clinical experts, and other sources. This new set of 84 studies was used as a quasi gold standard (QGS against which more than 300 combinations of the five approaches could be tested. To create the set of possible approaches, the researchers combined search strategies one through four in all possible ways, and used all available subheading combinations from 2a and 2b. The Badgett

    Effects of Timing of Adversity on Adolescent and Young Adult Adjustment Abstract Exposure to adversity during childhood and adolescence predicts adjustment across development. Further, adolescent adjustment problems persist into young adulthood. This study examined relations of contextual adversity with concurrent adolescent adjustment and prospective mental health and health outcomes in young adulthood. A longitudinal sample (N = 808) was followed from age 10 through 27. Perceptions of neighborhood in childhood predicted depression, alcohol use disorders, and HIV risk in young adulthood. Further, the timing of adversity was important in determining the type of problem experienced in adulthood. Youth adjustment predicted adult outcomes, and in some cases, mediated the relation between adversity and outcomes. These findings support the importance of adversity in predicting adjustment and elucidate factors that affect outcomes into young adulthood. PMID:22754271

    Pain is a widespread symptom in clinical practice. Older adults and chronically ill patients are particularly affected. In multimorbid geriatric patients, pharmacological pain treatment is an extension of a previously existing multimedication. Besides the efficacy of pain treatment, drug side effects and drug-drug interactions have to be taken into account to minimize the health risk for these patients. Apart from the number of prescriptions, the age-related pharmacokinetic and pharmacodynamic changes significantly increase the risk among older adults. The use of non-steroidal anti-inflammatory drugs (NSAID) is widespread but NSAIDs have the highest risk of adverse drug reactions and drug interactions. In particular, the gastrointestinal, cardiovascular, renal and coagulation systems are affected. Apart from the known toxic effect on the liver (in high doses), paracetamol (acetaminophen) has similar risks although to a lesser degree. According to current data, metamizol is actually better than its reputation suggests. The risk of potential drug interactions seems to be low. Apart from the risk of sedation in combination with other drugs, tramadol and other opioids can induce the serotonin syndrome. Among older adults, especially in the case of polypharmacy, an individualized approach should be considered instead of sticking to the pain management recommended by the World Health Organization (WHO) in order to minimize drug-drug interactions and adverse drug reactions.

    Human immunoglobulin (IG) is used for IgG replacement therapy in primary and secondary immunodeficiency, for prevention and treatment of certain infections, and as an immunomodulatory agent for autoimmune and inflammatory disorders. IG has a wide spectrum of antibodies to microbial and human antigens. Several high-titered IGs are also available enriched in antibodies to specific viruses or bacterial toxins. IG can be given intravenously (IGIV), intramuscularly (IGIM) or by subcutaneous infusions (SCIG). Local adverse reactions such as persistent pain, bruising, swelling and erythema are rare with IGIV infusions but common (75%) with SCIG infusions. By contrast, adverse systemic reactions are rare with SCIG infusions but common with IGIV infusions, occurring as often as 20% to 50% of patients and 5% to 15% of all IGIV infusions. Systemic adverse reactions can be immediate (60% of reactions) occurring within 6 hours of an infusion, delayed (40% of reactions) occurring 6 hours-1 week after an infusion, and late (less than 1% of reactions), occurring weeks and months after an infusion. Immediate systemic reactions such as head and body aches, chills and fever are usually mild and readily treatable. Immediate anaphylactic and anaphylactoid reactions are uncommon. The most common delayed systemic reaction is persistent headache. Less common but more serious delayed reactions include aseptic meningitis, renal failure, thromboembolism, and hemolytic reactions. Late reactions are uncommon but often severe, and include lung disease, enteritis, dermatologic disorders and infectious diseases. The types, incidence, causes, prevention, and management of these reactions are discussed. PMID:23835249

    Ship engine emissions are important regarding lung and cardiovascular diseases in coastal regions worldwide. Bio mass burning is made responsible for adverse health effects in many cities and rural regions. The Virtual Helmholtz Institute-HICE (www.hice-vi.eu) addresses chemical & physical properties and health effects of anthropogenic combustion emissions. Typical lung cell responses to combustion aerosols include inflammation and apoptosis, but a molecular link with the specific chemical composition in particular of ship emissions has not been established. Through an air-liquid interface exposure system (ALI), we exposed human lung cells at-site to exhaust fumes from a ship engine running on common heavy fuel oil (HFO) and cleaner-burning diesel fuel (DF) as well as to emissions of wood combustion compliances. A special field deployable ALI-exposition system and a mobile S2-biological laboratory were developed for this study. Human alveolar basal epithelial cells (A549 etc.) are ALI-exposed to fresh, diluted (1:40-1:100) combustion aerosols and subsequently were toxicologically and molecular-biologically characterized. Advanced chemical analyses of the exhaust aerosols were combined with transcriptional, proteomic and metabolomic profiling to characterise the cellular responses. The HFO ship emissions contained high concentrations of toxic compounds (transition metals, organic toxicants) and particle masses. The cellular responses included inflammation and oxidative stress. Surprisingly, the DF ship emissions, which predominantly contain rather "pure" carbonaceous soot and much less known toxicants, induced significantly broader biological effects, affecting essential cellular pathways (e.g., mitochondrial function and intracellular transport). Therefore the use of distillate fuels for shipping (this is the current emission reduction strategy of the IMO) appears insufficient for diminishing health effects. The study suggests rather reducing the particle emissions

    Radiation exposure in space is expected to increase the risk of cancer and other adverse biological effects in astronauts. The types of space radiation of particular concern for astronaut health are protons and heavy ions known as high atomic number and high energy (HZE) particles. Recent studies have indicated that carcinogenesis induced by protons and HZE particles may be modifiable. We have been evaluating the effects of proton and HZE particle radiation in cultured human cells and animals for nearly a decade. Our results indicate that exposure to proton and HZE particle radiation increases oxidative stress, cytotoxicity, cataract development and malignant transformation in in vivo and/or in vitro experimental systems. We have also shown that these adverse biological effects can be prevented, at least partially, by treatment with antioxidants and some dietary supplements that are readily available and have favorable safety profiles. Some of the antioxidants and dietary supplements are effective in preventing radiation induced malignant transformation in vitro even when applied several days after the radiation exposure. Our recent progress is reviewed and discussed in the context of the relevant literature.

    Full Text Available Abstract Background This study examined sociodemographic, physical and mental health, and adult and childhood adverse experiences associated with binge drinking in a representative sample of women in the State of California. Materials and methods Data were from the 2003 to 2004 (response rates of 72% and 74%, respectively California Women's Health Survey (CWHS, a population-based, random-digit-dial annual probability survey sponsored by the California Department of Health Services. The sample was 6,942 women aged 18 years or older. Results The prevalence of binge drinking was 9.3%. Poor physical health, and poorer mental health (i.e., symptoms of PTSD, anxiety, and depression, feeling overwhelmed by stress, were associated with binge drinking when demographics were controlled, as were adverse experiences in adulthood (intimate partner violence, having been physically or sexually assaulted, or having experienced the death of someone close and in childhood (living with someone abusing substances or mentally ill, or with a mother vicimized by violence, or having been physically or sexually assaulted. When adult mental health and adverse experiences were also controlled, having lived as a child with someone who abused substances or was mentally ill was associated with binge drinking. Associations between childhood adverse experiences and binge drinking could not be explained by women's poorer mental health status in adulthood. Conclusion Identifying characteristics of women who engage in binge drinking is a key step in prevention and intervention efforts.

    Whereas the adverse impact of attention-deficit/hyperactivity disorder (ADHD) on emotional and psychosocial well-being has been well investigated, its impact on physical health has not. The main aim of this study was to assess the impact of ADHD on lifestyle behaviors and measures of adverse health risk indicators. Subjects were 100 untreated adults with ADHD and 100 adults without ADHD of similar age and sex. Unhealthy lifestyle indicators included assessments of bad health habits, frequency of visits to healthcare providers, and follow through with recommended prophylactic tests. Assessments of adverse health risk indicators included measurements of cardiovascular and metabolic parameters, weight, body mass index, and waist circumference. No differences were identified in health habits between subjects with and without ADHD, but robust differences were found in a wide range of adverse health risk indicators. ADHD is associated with an adverse impact in health risk indicators well known to be associated with high morbidity and mortality. PMID:25211634

  15. Towards a multidisciplinary and integrated strategy in the assessment of adverse health effects related to air pollution: The case study of Cracow (Poland) and asthma

    International Nuclear Information System (INIS)

    Complex interaction between anthropogenic activities, air quality and human health in urban areas, such as in Cracow sustains the need for the development of an interdisciplinary and integrated risk-assessment methodology. In such purpose, we propose a pilot study performed on asthmatics and based on a combined use of a biomarker, such as metallothionein 2A (MT-2A) in the characterization of human exposure to one or a mixture of pollutants and of Geographical Information Systems (G.I.S.) which integrates climatic and urban anthropogenic parameters in the assessment of spatio-temporal dispersion of air pollutants. Considering global incidence of air pollution on asthma and on peripheral blood lymphocytes MT-2A expression should provide a complementary information on biological risks linked to urban anthropogenic activities. Such study would help for the establishment of a sustainable development in urban areas that can maintain the integrity of air quality and preserve human health. - An integrative risk methodology based on both geographic and molecular biological approaches is proposed for the assessment of asthmatics exposure to urban air pollution

    2007-07-01

    Full Text Available Abstract Background As every healthcare intervention carries some risk of harm, clinical decision making needs to be supported by a systematic assessment of the balance of benefit to harm. A systematic review that considers only the favourable outcomes of an intervention, without also assessing the adverse effects, can mislead by introducing a bias favouring the intervention. Much of the current guidance on systematic reviews is directed towards the evaluation of effectiveness; but this differs in important ways from the methods used in assessing the safety and tolerability of an intervention. A detailed discussion of why, how and when to include adverse effects in a systematic review, is required. Methods This discussion paper, which presupposes a basic knowledge of systematic review methodology, was developed by consensus among experienced reviewers, members of the Adverse Effects Subgroup of The Cochrane Collaboration, and supplemented by a consultation of content experts in reviews methodology, as well as those working in drug safety. Results A logical framework for making decisions in reviews that incorporate adverse effects is provided. We explore situations where a comprehensive investigation of adverse effects is warranted and suggest strategies to identify practicable and clinically useful outcomes. The advantages and disadvantages of including observational and experimental study designs are reviewed. The consequences of including separate studies for intended and unintended effects are explained. Detailed advice is given on designing electronic searches for studies with adverse effects data. Reviewers of adverse effects are given general guidance on the assessment of study bias, data collection, analysis, presentation and the interpretation of harms in a systematic review. Conclusion Readers need to be able to recognize how strategic choices made in the review process determine what harms are found, and how the findings may affect

  18. Does cannabidiol protect against adverse psychological effects of THC?

    Directory of Open Access Journals (Sweden)

    Raymond J.M. eNiesink

    2013-10-01

    Full Text Available The recreational use of cannabis can have persistent adverse effects on mental health. Delta-9-tetrahydrocannabinol (THC is the main psychoactive constituent of cannabis, and most, if not all, of the effects associated with the use of cannabis are caused by THC. Recent studies have suggested a possible protective effect of another cannabinoid, cannabidiol (CBD. A literature search was performed in the bibliographic databases PubMed, PsycINFO and Web of Science using the keyword ‘cannabidiol.’ After removing duplicate entries, 1295 unique titles remained. Based on the titles and abstracts, an initial selection was made. The reference lists of the publications identified in this manner were examined for additional references. Cannabis is not a safe drug. Depending on how often someone uses, the age of onset, the potency of the cannabis that is used and someone's individual sensitivity, the recreational use of cannabis may cause permanent psychological disorders. Most recreational users will never be faced with such persistent mental illness, but in some individuals cannabis use leads to undesirable effects: cognitive impairment, anxiety, paranoia and increased risks of developing chronic psychosis or drug addiction. Studies examining the protective effects of CBD have shown that CBD can counteract the negative effects of THC. However, the question remains of how the laboratory results translate to the types of cannabis that are encountered by real-world recreational users.

  2. Ground level ozone (O3) associated with radon (222Rn) and particulate matter (PM) concentrations in Bucharest metropolitan area and adverse health effects

    International Nuclear Information System (INIS)

    The aim of this paper is to contribute with new information in the application of ground based radon (222Rn) observations to atmospheric research, namely its relation with air pollution due to ground-level ozone (O3) and particle matter in two size fractions (PM10 and PM2.5) for Bucharest metropolitan area in Romania. During January 1-December 31, 2011, ground levels of radon, ozone and particulate matter (PM) have been continuously monitored in synergy with the main meteorological parameters (air temperature, humidity and pressure), and daily global air quality indices. A systematic analysis of surface ozone observations of ground level radon, ozone and PM is presented. Observational results indicate the following yearly daily mean ground level concentrations: 40.26 ± 7.54 Bq/m3 for radon, 90.51 μg/m3 for ozone, 35.96 μg/m3 for PM2.5, and 40.91 μg/m3 for PM10. The assessment of the results showed the influence of local and meteorological conditions on the daily mean radon, ozone and PM concentrations. However, in densely populated metropolitan area of Bucharest the mean daily values of ozone, PM2.5, PM10, and attached 222Rn are sometimes higher than European Community limit values leading to serious public concern during the last years. Due to the high risk of increased levels of O3, PM2.5, PM10, and attached 222Rn on human health respiratory function (especially for children and older persons), and urban green, the results are very useful for atmospheric, radiological protection, epidemiological and environmental studies.

    2013-02-01

    This overview of systematic reviews (SRs) aims to evaluate critically the evidence regarding the adverse effects of herbal medicines (HMs). Five electronic databases were searched to identify all relevant SRs, with 50 SRs of 50 different HMs meeting our inclusion criteria. Most had only minor weaknesses in methods. Serious adverse effects were noted only for four HMs: Herbae pulvis standardisatus, Larrea tridentate, Piper methysticum and Cassia senna. The most severe adverse effects were liver or kidney damage, colon perforation, carcinoma, coma and death. Moderately severe adverse effects were noted for 15 HMs: Pelargonium sidoides, Perna canaliculus, Aloe vera, Mentha piperita, Medicago sativa, Cimicifuga racemosa, Caulophyllum thalictroides, Serenoa repens, Taraxacum officinale, Camellia sinensis, Commifora mukul, Hoodia gordonii, Viscum album, Trifolium pratense and Stevia rebaudiana. Minor adverse effects were noted for 31 HMs: Thymus vulgaris, Lavandula angustifolia Miller, Boswellia serrata, Calendula officinalis, Harpagophytum procumbens, Panax ginseng, Vitex agnus-castus, Crataegus spp., Cinnamomum spp., Petasites hybridus, Agave americana, Hypericum perforatum, Echinacea spp., Silybum marianum, Capsicum spp., Genus phyllanthus, Ginkgo biloba, Valeriana officinalis, Hippocastanaceae, Melissa officinalis, Trigonella foenum-graecum, Lagerstroemia speciosa, Cnicus benedictus, Salvia hispanica, Vaccinium myrtillus, Mentha spicata, Rosmarinus officinalis, Crocus sativus, Gymnema sylvestre, Morinda citrifolia and Curcuma longa. Most of the HMs evaluated in SRs were associated with only moderately severe or minor adverse effects. PMID:23472485

    Study objective: To evaluate if the effects of particulate matter (PM10) on respiratory mortality of elderly people are affected by socioeconomic status. Design: Time series studies. The daily number of elderly respiratory deaths were modelled in generalised linear Poisson regression models controlling for long term trend, weather, and day of the week, from January 1997 to December 1999, in six different regions of São Paulo City, Brazil. The regions were defined according to the proximity of air pollution monitoring stations. Three socioeconomic indicators were used: college education, monthly income, and housing. Main results: For a 10 µg/m3 increase in PM10, the percentage increase in respiratory mortality varied from 1.4% (95% CI 5.9 to 8.7) to 14.2% (95% CI 0.4 to 28.0). The overall percentage increase in the six regions was 5.4% (95% CI 2.3 to 8.6). The effect of PM10 was negatively correlated with both percentage of people with college education and high family income, and it was positively associated with the percentage of people living in slums. Conclusions: These results suggest that socioeconomic deprivation represents an effect modifier of the association between air pollution and respiratory deaths. PMID:14684725

    Adverse childhood experiences (ACEs), including child abuse, have been linked with poor health outcomes in adulthood. The mechanisms that explain these relations are less understood. This study assesses whether associations of ACEs and health risks are mediated by adult socioeconomic conditions, and whether these pathways are different for maltreatment than for other types of adversities. Using the Behavioral Risk Factor Surveillance System 2012 survey (N=29,229), we employ structural equation modeling to (1) estimate associations of the number and type of ACEs with five health risks-depression, obesity, tobacco use, binge drinking, and self-reported sub-optimal health; and (2) assess whether adult socioeconomic conditions-marriage, divorce and separation, educational attainment, income and insurance status-mediate those associations. Findings suggest both direct and indirect associations between ACEs and health risks. At high numbers of ACEs, 15-20% of the association between number of ACEs and adult health risks was attributable to socioeconomic conditions. Associations of three ACEs (exposure to domestic violence, parental divorce, and residing with a person who was incarcerated) with health risks were nearly entirely explained by socioeconomic conditions in adulthood. However, child physical, emotional, and sexual abuse were significantly associated with several adult health risks, beyond the effects of other adversities, and socioeconomic conditions explained only a small portion of these associations. These findings suggest that the pathways to poor adult health differ by types of ACEs, and that childhood abuse is more likely than other adversities to have a direct impact. PMID:26059537

We describe four cases of probable nootropic-induced psychiatric adverse effects to illustrate this theory. To the best of our knowledge this has not been previously reported in the formal medical literature. We briefly describe the most common classes of nootropics, including their postulated or proven methods of actions, their desired effects, and their adverse side effects, and provide a brief discussion of the cases. Our objective is to raise awareness among physicians in general and psychiatrists and addiction specialists in particular of the potentially dangerous phenomenon of unsupervised nootropic use among young adults who may be especially vulnerable to nootropics’ negative effects.

    Full Text Available Background: Misuse of topical corticosteroids is a widespread phenomenon among young people in India, especially women. The practice is associated with significant adverse effects and poor awareness of these effects among the general public. Aim: This study was conducted to examine the misuse and adverse effects of topical corticosteroids among the people in Bastar region in Chhattisgarh state of India. Materials and Methods: Data collected from patients presenting with at least one of the adverse effects of topical corticosteroids as the chief complaint, from November 2010 to October 2011. Results: Out of the 6723 new patients, 379 (5.63% had presented with misuse and adverse effects of topical corticosteroids, of whom 78.89% were females. More than 65% of the patients were in the age group 10-29 years. The main reason for using the topical corticosteroids was to lighten skin colour and treat melasma and suntan. Acne (37.99% and telangiectasia (18.99% were the most common adverse effects noted. Conclusions: Misuse of topical corticosteroids has a huge impact on dermatological practice, leading to a significant proportion of visits to the dermatologist. This hydra-headed problem needs multi-dimensional interventions, involving educational, legal and managerial approaches with cooperation from different sectors of society.

    Full Text Available Introduction: The use of nutritional supplements is prevalent among physical exercise practitioners and some adverse effects have been reported, however not sufficiently substantial, because they originate from isolated cases. Objectives: Investigate nutritional supplements consumption prevalence and adverse effects of the use of such products. Methods: An epidemiological, representative and transversal study, with 180 physical exercise practitioners in gyms, who answered questionnaires about sports supplementation, associated factors and self-perceived adverse effects. In a subsample of 86 individuals, blood pressure was measured and blood was collected for the evaluation of lipid profile markers, hepatic and renal function. Results: The supplementation prevalence level was 58.3%, whereas the physicians and nutritionists indicated only 21.9%. The reported adverse effects were observed only by supplement users (acne, insomnia, aggressiveness, headaches and tachycardia. Systolic blood pressure was higher in the supplemented group when compared to the control group (p = 0.04, as in the subgroup of thermogenic users (p < 0.0001 and among those who had consumed any type of supplementation for over 2 years (p = 0.005. Serum creatinine levels were higher only in the subgroup of carbohydrates when compared to the control group (p = 0.03. Diastolic blood pressure, lipid profile and hepatic function did not present differences between groups. Conclusions: The use of nutritional supplements without specialized orientation was elevated among physical exercise practitioners, being associated to adverse effects both by the users themselves and by clinical diagnosis.

  10. Adverse effects and treatment on palliative radiotherapy for bone metastases

    International Nuclear Information System (INIS)

    Adverse effects on palliative radiotherapy for bone metastases are generally mild. Acute and late adverse effects are similar between 8 Gy single fraction and multi-fraction radiotherapy (e.g. 30 Gy in 10 fractions). Both external beam radiotherapy and radiopharmaceutical therapy with strontium-89 may cause pain flare. A randomized controlled trial is currently performed to confirm the effectiveness of dexamethasone for the prevention of pain flare. Reirradiation for the same site is widely used. However, its safeness has not been confirmed enough. Radiation myelitis is an unrecoverable severe adverse effect. However, the tolerated accumulated dose for the spinal cord is not fully understood. Stereotactic body radiotherapy may be considered to deliver reirradiation for spinal metastases without exposing too much dose for the spinal cord. Another solution to prevent radiation myelitis after reirradiation may use dose fractionations of 8 Gy single or 20 Gy in 5 fractions instead of 30 Gy in 10 fractions. (author)

    International Nuclear Information System (INIS)

    DTC is considered the most common endocrine neoplasm, and 131I therapy has been proven to be an important component in the management strategy. Currently, most research focuses on the adverse effects of radiation exposure to 131I therapy. Some results, based on large-scale and long-term investigation,show new information. Although 131I therapies are usually well tolerated, clinicians involved in the management of DTC need to be aware of the potential toxicity of 131I and take all measures to reduce these effects to a minimum. The aim of this review is to present the adverse effects of 131I therapy for DTC. (authors)

    This study examined the utility of a lifetime cumulative adversities and trauma model in predicting the severity of mental health symptoms of depression, anxiety, and posttraumatic stress disorder. We also tested whether ethnicity and gender moderate the effects of this stress exposure construct on mental health using multigroup structural equation modeling. A sample of 500 low-socioeconomic status African American and Latino men and women with histories of adversities and trauma were recruited and assessed with a standard battery of self-report measures of stress and mental health. Multiple-group structural equation models indicated good overall model fit. As hypothesized, experiences of discrimination, childhood family adversities, childhood sexual abuse, other childhood trauma, and chronic stresses all loaded on the latent cumulative burden of adversities and trauma construct (CBAT). The CBAT stress exposure index in turn predicted the mental health status latent variable. Although there were several significant univariate ethnic and gender differences, and ethnic and gender differences were observed on several paths, there were no significant ethnic differences in the final model fit of the data. These findings highlight the deleterious consequences of cumulative stress and trauma for mental health and underscore a need to assess these constructs in selecting appropriate clinical interventions for reducing mental health disparities and improving human health.

    2016-09-01

    More than 10 million people are imprisoned worldwide, and the prevalence of all investigated mental disorders is higher in prisoners than in the general population. Although the extent to which prison increases the incidence of mental disorders is uncertain, considerable evidence suggests low rates of identification and treatment of psychiatric disorders. Prisoners are also at increased risk of all-cause mortality, suicide, self-harm, violence, and victimisation, and research has outlined some modifiable risk factors. Few high quality treatment trials have been done on psychiatric disorders in prisoners. Despite this lack of evidence, trial data have shown that opiate substitution treatments reduce substance misuse relapse and possibly reoffending. The mental health needs of women and older adults in prison are distinct, and national policies should be developed to meet these. In this Review, we present clinical, research, and policy recommendations to improve mental health care in prisons. National attempts to meet these recommendations should be annually surveyed.

    Although in the last two decades the World Health Organization (WHO) has introduced tuberculosis as “a threat to global”, the vaccination with the Mycobacterium bovis Bacillus Calmette-Guerin (BCG) is the only way for the prevention of this fatal infectious disease. Despite of the efficacy of BCG vaccine especially against infants’ meningitis, it has still some limitations due to a variety of adverse effects. Many studies have evaluated the side effects of different strains of BCG vaccines in different countries. In Iran, some studies have been done so far to evaluate the adverse effects of 1173 P2 strain which is used for BCG vaccination. Each of these studies have used different standardization and sampling methods.

    Full Text Available Many wild plants around us have beneficial effects on our body and can be used as food. People are more and more interested in the medicinal plants. Many of them began gathering and preparing plants for the relief of symptoms of diseases or as a food dietary. Due to the lack of knowledge of plants, mistaking plants that contain toxins for medical plants may happen and cause adverse effects or even poisoning. The Poison Control Centre in Ljubljana keeps records of patients who have been admitted to the department because of adverse effects from the ingestion of certain plants. We analysed 64 cases, which were registered by the Poison Control Centre between January 2000 and December 2013. The aim of the present study was to determine which plants cause the most intoxications in Slovenia.

    Full Text Available Topiramate, an antiepileptic drug is reported to cause various ocular adverse effects like acute onset myopia, glaucoma. Visual field defect is an uncommon, serious treatment emergent adverse effect. We are reporting two cases of suspected topiramate induced visual field defects. Both the cases were on topiramate for more than 6 months as add-on therapy at daily doses ranging from 100-150mg. The presenting complaints were insidious onset visual disturbances. Diagnosis was based of temporal association with drug intake, clinical examination and investigations. Automated perimetry revealed bilateral superior quadrantic and arcuate field defects in the two cases respectively. Marked improvement with drug dechallenge was noted which was also corroborated by perimetry. Using Naranjo′s ADR Probability Scale, both cases revealed a "probable" association with topiramate. This report intends to improve awareness amongst clinicians to facilitate early diagnosis and intervention.

    Full Text Available AIM: Adverse drug reaction is noxious and unwanted reaction to drugs at dose used in humans for diagnosis, treatment or prophylaxis. Adverse drug reaction monitoring is an area of drug information that has been given little attention yet. Spontaneous reporting is currently the major back bone for the detection of adverse drug reactions. The objective of this study was to assess the knowledge, attitude and practices of adverse drug reaction reporting among health professionals in selected health facilities in southwest Ethiopia. METHOD: A cross-sectional study design was used among health professionals in selected health facilities in January 2010. Prescribers other than physicians, junior pharmacy technicians and also health assistants were excluded. Data was collected using self administered questionnaires from volunteered physicians (Medical interns and above, nurses (Diploma and above and Pharmacy professionals (Diploma and above and analyzed using SPSS version 16.0. RESULTS: A total of 82 health professionals were participated in the study. From those 82 participants, only 19 (23.17% and 21 (25.61% knew the existence of national reporting system and a yellow card of adverse drug reaction reporting form. Thirteen (15.85% participants encountered adverse drug reaction in the past 12 months in their clinical activities, but none of them reported to responsible body. Even though the participants’ knowledge and practice were inadequate, most of the respondents 47 (57.31% agreed that adverse drug reaction reporting is part of duty of them and important to the public in general and to the patient in particular. CONCLUSION: There was no documentation and reporting of adverse drug reaction, which might partly be explained by lack of knowledge and misconceptions about spontaneous reporting. Our study strongly suggests that there is a great need to create awareness and to promote the reporting of adverse drug reaction amongst health professionals

    Full Text Available Elderly adults should avoid medications with anticholinergic effects since they may increase the risk of adverse events, including falls, delirium, and cognitive impairment. However, data on anticholinergic burden are limited in subpopulations, such as individuals with Parkinson disease (PD. The objective of this study was to determine whether anticholinergic burden was associated with adverse outcomes in a PD inpatient population.Using the Cerner Health Facts® database, we retrospectively examined anticholinergic medication use, diagnoses, and hospital revisits within a cohort of 16,302 PD inpatients admitted to a Cerner hospital between 2000 and 2011. Anticholinergic burden was computed using the Anticholinergic Risk Scale (ARS. Primary outcomes were associations between ARS score and diagnosis of fracture and delirium. Secondary outcomes included associations between ARS score and 30-day hospital revisits.Many individuals (57.8% were prescribed non-PD medications with moderate to very strong anticholinergic potential. Individuals with the greatest ARS score (≥ 4 were more likely to be diagnosed with fractures (adjusted odds ratio (AOR: 1.56, 95% CI: 1.29-1.88 and delirium (AOR: 1.61, 95% CI: 1.08-2.40 relative to those with no anticholinergic burden. Similarly, inpatients with the greatest ARS score were more likely to visit the emergency department (adjusted hazard ratio (AHR: 1.32, 95% CI: 1.10-1.58 and be readmitted (AHR: 1.16, 95% CI: 1.01-1.33 within 30-days of discharge.We found a positive association between increased anticholinergic burden and adverse outcomes among individuals with PD. Additional pharmacovigilance studies are needed to better understand risks associated with anticholinergic medication use in PD.

    This study aimed to measure the relative contribution of adverse experiences to adolescent behavioral health problems using administrative data. Specifically, we sought to understand the predictive value of adverse experiences on the presence of mental health and substance abuse problems for youth receiving publicly funded social and health services. Medicaid claims and other service records were analyzed for 125,123 youth age 12-17 and their biological parents. Measures from administrative records reflected presence of parental domestic violence, mental illness, substance abuse, criminal justice involvement, child abuse and/or neglect, homelessness, and death of a biological parent. Mental health and substance abuse status of adolescents were analyzed as functions of adverse experiences and other youth characteristics using logistic regression. In multivariate analyses, all predictors except parental domestic violence were statistically significant for substance abuse; parental death, parental mental illness, child abuse or neglect and homelessness were statistically significant for mental illness. Odds ratios for child abuse/neglect were particularly high in both models. The ability to identify risks during childhood using administrative data suggests the potential to target prevention and early intervention efforts for children with specific family risk factors who are at increased risk for developing behavioral health problems during adolescence. This study illustrates the utility of administrative data in understanding adverse experiences on children and the advantages and disadvantages of this approach. PMID:26234784

Self-assessed health, burnout-scores and well-being are commonly used as outcome measures. Few studies have used sick-leave to compare effects of stress interventions. A new approach is to use nature and garden in a multimodal stress management context. This study aimed to explore effects on burnout, work ability, stress-related health symptoms, and sick leave for 33 women participating in a 12-weeks nature based stress management course and to investigate how the nature/garden activities were experienced. A mixed method approach was used. Measures were taken at course start and three follow-ups. Results showed decreased burnout-scores and long-term sick leaves, and increased work ability; furthermore less stress-related symptoms were reported. Tools and strategies to better handle stress were achieved and were widely at use at all follow-ups. The garden and nature content played an important role for stress relief and for tools and strategies to develop. The results from this study points to beneficial effects of using garden activities and natural environments in a stress management intervention.

    Recent systematic reviews have emphasized the need for more research into the health and social impacts of adverse childhood experiences (ACEs) in the Asia-Pacific region. This cross-sectional study was conducted with 2099 young adult students in 8 medical universities throughout Vietnam. An anonymous, self-report questionnaire included the World Health Organization ACE-International Questionnaire and standardized measures of mental and physical health. Three quarters (76%) of the students reported at least one exposure to ACEs; 21% had 4 or more ACEs. The most commonly reported adversities were emotional abuse, physical abuse, and witnessing a household member being treated violently (42.3%, 39.9%, and 34.6%, respectively). Co-occurrence of ACEs had dose-response relationships with poor mental health, suicidal ideation, and low physical health-related quality of life. This first multisite study of ACEs among Vietnamese university students provided evidence that childhood adversity is common and is significantly linked with impaired health and well-being into the early adult years.

  20. Macrophages are involved in hexachlorobenzene-induced adverse immune effects

    International Nuclear Information System (INIS)

    Hexachlorobenzene (HCB) is a persistent environmental pollutant that causes adverse immune effects in man and rat. The Brown Norway (BN) rat is very susceptible to HCB-induced immunopathology and oral exposure causes inflammatory skin and lung lesions, splenomegaly, lymph node (LN) enlargement, and increased serum levels of IgE and anti-ssDNA IgM. T cells play an important role but do not account for all adverse effects induced by HCB. Macrophages are probably also important and the relationship between macrophages and T cells was further investigated. To eliminate macrophages clodronate-liposomes were used. Furthermore, a kinetic study was performed to obtain insight in the early phase of the HCB-induced immune response. Also, experiments were performed to detect specific memory T cells. Therefore, an adoptive transfer study was performed. Our results indicate that macrophages are indeed involved in HCB-induced skin lesions, lung eosinophilia, and elevation of IgM against ssDNA. Kinetics showed that both skin and lung lesions appeared early after exposure. Moreover, immune effects could not be adaptively transferred. Thus, both macrophages and T cells are involved in HCB-induced immune effects but HCB exposure does not lead to specific T cell sensitization. Presumably, HCB exposure induces macrophage activation, thereby generating adjuvant signals that polyclonally stimulate T cells. Together, these events may lead to the observed immunopathology in BN rats

    BACKGROUND: Bevacizumab is humanized monoclonal antibody inhibiting angiogenesis and the only FDA approved treatment for recurrent glioblastoma. The aim of this study was to look at the occurrence of various adverse effects associated with use of bevacizumab in recurrent glioblastoma. METHODS: In this retrospective chart review, we studied 280 patients with recurrent glioblastoma treated with Bevacizumab between 2005-2011 to characterize the known adverse effects of bevacizumab including hypertension, grade 3-4 myelosuppression, wound healing complications, thrombo-embolic events, stroke, hemorrhage and gastrointestinal complications. RESULTS: The study population included 168 males and 112 females. The median age was 53.5 years(range 8.1-81.3). TREATMENT: Bevacizumab only(58), Bevacizumab + CPT(11), Bevacizumab + TMZ(32) or Bevacizumab + Other(34). Patients were treated at recurrence(1st = 96; 2nd = 126, 3rd = 58). Hypertension was the most common adverse effect occurring in 131(49%). The median duration from treatment start to development was 82 days (Range 7-1143). However, only 33(25%) were started on antihypertensive medication. Grade 3-4 Myelosuppression occurred in 52(19%)causing treatment discontinuation in 8. Thrombo-embolic events were reported in 5%(15) patients including DVT(9), PE(2), Central venous thrombosis(1) and Stroke(3). Thirty-six patients (13%) were on anti-coagulant medication at bevacizumab initiation. Median time to a thromboembolic complication was 113 days (Range 8-1145). Wound healing complications were noted in 7(3%) patients, 3 craniotomy dehiscence and 4 at soft tissue sites. Five patients (2%) developed GI complications, including perforations(3), pancreatitis(1), and diverticulitis(1). Median time to development was 92 days(Range 10-651). There was a high rate 46%(129) of grade 3-4 lymphocytopenia; median time to develop lymphocytopenia was 50 days(Range = 3-564). CONCLUSION: The range of toxicities was similar to other reports

    Advances in fields of inquiry as diverse as neuroscience, molecular biology, genomics, developmental psychology, epidemiology, sociology, and economics are catalyzing an important paradigm shift in our understanding of health and disease across the lifespan. This converging, multidisciplinary science of human development has profound implications for our ability to enhance the life prospects of children and to strengthen the social and economic fabric of society. Drawing on these multiple streams of investigation, this report presents an ecobiodevelopmental framework that illustrates how early experiences and environmental influences can leave a lasting signature on the genetic predispositions that affect emerging brain architecture and long-term health. The report also examines extensive evidence of the disruptive impacts of toxic stress, offering intriguing insights into causal mechanisms that link early adversity to later impairments in learning, behavior, and both physical and mental well-being. The implications of this framework for the practice of medicine, in general, and pediatrics, specifically, are potentially transformational. They suggest that many adult diseases should be viewed as developmental disorders that begin early in life and that persistent health disparities associated with poverty, discrimination, or maltreatment could be reduced by the alleviation of toxic stress in childhood. An ecobiodevelopmental framework also underscores the need for new thinking about the focus and boundaries of pediatric practice. It calls for pediatricians to serve as both front-line guardians of healthy child development and strategically positioned, community leaders to inform new science-based strategies that build strong foundations for educational achievement, economic productivity, responsible citizenship, and lifelong health.

    The athletic performance supplement industry is a multibillion-dollar business and one popular category claims to increase nitric oxide (NO) production. We report three patients presenting to the emergency department with adverse effects. A 33-year-old man presented with palpitations, dizziness, vomiting, and syncope, after the use of NO(2) platinum. His examination and electrocardiogram (ECG) were normal. The dizziness persisted, requiring admission overnight. A 21-year-old man with palpitations and near syncope had used a "nitric oxide" supplement. He was tachycardic to 115 bpm with otherwise normal examination. Laboratory values including methemoglobin, and ECG were unremarkable. He was treated with 1 L of saline with no change in heart rate. He was admitted for observation. A 24-year-old man presented after taking NO-Xplode with palpitations and a headache. His examination, laboratory values, and ECG were normal. He was discharged. The purported active ingredient in these products is arginine alpha-ketoglutarate (AAKG), which is claimed to increase NO production by supplying the precursor L-arginine. The symptoms could be due to vasodilation from increased levels of NO, though other etiologies cannot be excluded. AAKG containing supplements may be associated with adverse effects requiring hospital admission. PMID:19755457

    The adverse effects of administration of gentamicin (5 mg/kg of body weight, IM, q 12 h) for 7 days were studied in healthy scarlet macaws (Ara macao) and galahs (Eolophus roseicapillus; cockatoos). Polydipsia and polyuria developed in each species, but were greater and persisted longer in the cockatoos. Peak water intake in the cockatoos more than quadrupled, and remained increased for 23 days after cessation of gentamicin administration. Plasma aspartate transaminase activity increased significantly (P less than 0.05) after treatment in the macaws, and plasma aspartate transaminase and lactate dehydrogenase activities increased in the cockatoos. Single IM administration of gentamicin (5 mg/kg) resulted in mean (+/- SEM) plasma concentration of 20.6 (+/- 1.85) micrograms/ml at 0.5 hour for either species of birds. There were no significant differences between mean plasma gentamicin concentrations for cockatoos and macaws at any time after drug administration, except at 12 hours, when values for cockatoos were significantly (P less than 0.05) greater than those for macaws. The elimination half-life for gentamicin after IM administration of 5 and 10 mg/kg was 1.17 and 1.07 hours, respectively, for macaws and 1.23 and 1.44 hours, respectively, for cockatoos. Correlation between drug disposition and adverse side effects could not be detected. PMID:2316918

    Botox® injections are taking a consistently increasing place in urology. Intracremasteric injections, particularly, have been applied for cryptorchidism and painful testicular spasms. Studies outlining their safety for this use are, however, scanty. Thus, the present study aimed at evaluating possible testicular toxicity of Botox® injections and their effect on male fertility. Mature rats were given intracremasteric Botox® injections (10, 20 and 40 U/kg) three times in a two-week interval. Changes in body and testes weights were examined and gonadosomatic index compared to control group. Semen quality, sperm parameters, fructose, protein, cholesterol and triglycerides contents were assessed. Effects on normal testicular function were investigated by measuring testosterone levels and changes in enzyme activities (lactate dehydrogenase-X and acid phosphatase). To draw a complete picture, changes in oxidative and inflammatory states were examined, in addition to the extent of connective tissue deposition between seminiferous tubules. In an attempt to have more accurate information about possible spermatotoxic effects of Botox®, flowcytometric analysis and histopathological examination were carried out. Botox®-injected rats showed altered testicular physiology and function. Seminiferous tubules were separated by dense fibers, especially with the highest dose. Flowcytometric analysis showed a decrease in mature sperms and histopathology confirmed the findings. The oxidative state was, however, comparable to control group. This study is the first to show that intracremasteric injections of Botox® induce adverse testicular effects evidenced by inhibited spermatogenesis and initiation of histopathological changes.

Previous studies have been vulnerable to possible selection bias. In the study reported here, we examined the association between self-rated health and adverse events in terms of cardiac events, cardiac readmissions, and all-cause mortality in a complete cohort of patients treated with percutaneous coronary intervention (PCI.Study design and setting: A cohort of patients with coronary heart disease treated with PCI was followed up with questionnaires 4 weeks after PCI to measure self-rated health and in registers to identify adverse events. Of 1,752 eligible patients under 67 years, 26 died during the first 4 weeks. A total of 224 patients were excluded from the analysis because they were readmitted with a cardiac diagnosis before answering the first questionnaire. We received complete SF-12 Health Survey component summaries from 984 of the remaining 1,502 patients. We used multiple imputation to establish a complete cohort, including nonrespondents.Results: During follow-up, 83 patients died, 220 patients experienced a new cardiac event, and 526 patients experienced a hospital readmission related to coronary heart disease. Poor self-rated health was related to cardiac events, cardiac readmission, and all-cause mortality. The associations were stronger for all-cause mortality than for events and readmissions. Physical health was more important than mental health, but both revealed an exposure–response pattern

    A new statistical methodology is developed for the analysis of spontaneous adverse event (AE) reports from post-marketing drug surveillance data. The method involves both empirical Bayes (EB) and fully Bayes estimation of rate multipliers for each drug within a class of drugs, for a particular AE, based on a mixed-effects Poisson regression model. Both parametric and semiparametric models for the random-effect distribution are examined. The method is applied to data from Food and Drug Administration (FDA)'s Adverse Event Reporting System (AERS) on the relationship between antidepressants and suicide. We obtain point estimates and 95 per cent confidence (posterior) intervals for the rate multiplier for each drug (e.g. antidepressants), which can be used to determine whether a particular drug has an increased risk of association with a particular AE (e.g. suicide). Confidence (posterior) intervals that do not include 1.0 provide evidence for either significant protective or harmful associations of the drug and the adverse effect. We also examine EB, parametric Bayes, and semiparametric Bayes estimators of the rate multipliers and associated confidence (posterior) intervals. Results of our analysis of the FDA AERS data revealed that newer antidepressants are associated with lower rates of suicide adverse event reports compared with older antidepressants. We recommend improvements to the existing AERS system, which are likely to improve its public health value as an early warning system. PMID:18404622

    2016-04-01

    The Aloe plant is employed as a dietary supplement in a variety of foods and as an ingredient in cosmetic products. The widespread human exposure and its potential toxic and carcinogenic activities raise safety concerns. Chemical analysis reveals that the Aloe plant contains various polysaccharides and phenolic chemicals, notably anthraquinones. Ingestion of Aloe preparations is associated with diarrhea, hypokalemia, pseudomelanosis coli, kidney failure, as well as phototoxicity and hypersensitive reactions. Recently, Aloe vera whole leaf extract showed clear evidence of carcinogenic activity in rats, and was classified by the International Agency for Research on Cancer as a possible human carcinogen (Group 2B). This review presents updated information on the toxicological effects, including the cytotoxicity, genotoxicity, carcinogenicity, and adverse clinical effects of Aloe vera whole leaf extract, gel, and latex.

    The immature kidney may be adversely affected by a variety of vasoactive or diuretic drugs, either administered to the mother during pregnancy, or to the neonate. Inhibitors of the angiotensin-converting enzyme administered to the hypertensive pregnant woman can severely and sometimes definitely impair renal function in the fetus, leading to postnatal anuria. Pathogenesis involves interference with the renin-angiotensin system and the prostaglandins. Beta-adrenergic agents administered during labor depress glomerular filtration rate transiently. Tolazoline, an alpha-adrenergic blocking agent useful in the treatment of persistent pulmonary hypertension of the neonate induces intense renal vasoconstriction with consequent hypoperfusion. Indomethacin, a prostaglandin synthetase inhibitor used for the pharmacological closure of a patent ductus arteriosus, also increases renal vascular resistance, and decreases urine output. Furosemide, the drug most often used in oliguric neonates, may also adversely affect the newborn infant. Its use has been associated with an increase in the incidence of patent ductus arteriosus, hypercalciuria, nephrocalcinosis and secondary hyperparathyroidism. These observations demonstrate that the proper use of drugs requires that the therapeutic endpoint be clearly defined and the predictable side effects be anticipated. PMID:2901276

    Social media offer insights of patients' medical problems such as drug side effects and treatment failures. Patient reports of adverse drug events from social media have great potential to improve current practice of pharmacovigilance. However, extracting patient adverse drug event reports from social media continues to be an important challenge for health informatics research. In this study, we develop a research framework with advanced natural language processing techniques for integrated and high-performance patient reported adverse drug event extraction. The framework consists of medical entity extraction for recognizing patient discussions of drug and events, adverse drug event extraction with shortest dependency path kernel based statistical learning method and semantic filtering with information from medical knowledge bases, and report source classification to tease out noise. To evaluate the proposed framework, a series of experiments were conducted on a test bed encompassing about postings from major diabetes and heart disease forums in the United States. The results reveal that each component of the framework significantly contributes to its overall effectiveness. Our framework significantly outperforms prior work. PMID:26518315

    Adverse Childhood Experiences (ACEs), which include family dysfunction and community-level stressors, negatively impact the health and well being of children throughout the life course. While several studies have examined the impact of these childhood exposures amongst racially and socially diverse populations, the contribution of ACEs in the persistence of socioeconomic disparities in health is poorly understood. To determine the association between ACEs and health outcomes amongst a sample of adults living in Philadelphia and examine the moderating effect of Socioeconomic Status (SES) on this association, we conducted a cross-sectional survey of 1,784 Philadelphia adults, ages 18 and older, using random digit dialing methodology to assess Conventional ACEs (experiences related to family dysfunction), Expanded ACEs (community-level stressors), and health outcomes. Using weighted, multivariable logistic regression analyses along with SES stratified models, we examined the relationship between ACEs and health outcomes as well as the modifying effect of current SES. High Conventional ACE scores were significantly associated with health risk behaviors, physical and mental illness, while elevated Expanded ACE scores were associated only with substance abuse history and sexually transmitted infections. ACEs did have some differential impacts on health outcomes based on SES. Given the robust impact of Conventional ACEs on health, our results support prior research highlighting the primacy of family relationships on a child's life course trajectory and the importance of interventions designed to support families. Our findings related to the modifying effect of SES may provide additional insight into the complex relationship between poverty and childhood adversity. PMID:26726759

    2008-09-01

    Depending on etiology, the esthetic treatment of dyschromia may involve vital tooth- bleaching techniques. Hydrogen peroxide is the active molecule used for such procedures; however, its action mechanism is not clearly understood. Moreover, a variety of contradictory studies make difficult the evaluation of the safety of bleaching techniques. The purpose of this article is therefore to review the available literature (1) to describe the physicochemical properties of hydrogen peroxide and (2) to assess the safety of its use as a vital tooth-bleaching agent. Indeed, based on hydrogen peroxide's capacity to generate free radicals that diffuse throughout the dental hard tissues, concerns have been addressed regarding the adverse effects that bleaching products can induce on the enamel and dentin structures, pulp, and bonding to a composite resin system. Moreover, during self-application of home bleaching products, hydrogen peroxide is released into the oral cavity and ingested. Some questions have therefore arisen concerning its toxicity and its possible carcinogenicity. PMID:19107251

    Causal factors in aviation accidents and incidents related to system/component failure/malfunction (SCFM) were examined for Federal Aviation Regulation Parts 121 and 135 operations to establish future requirements for the NASA Aviation Safety Program s Integrated Vehicle Health Management (IVHM) Project. Data analyzed includes National Transportation Safety Board (NSTB) accident data (1988 to 2003), Federal Aviation Administration (FAA) incident data (1988 to 2003), and Aviation Safety Reporting System (ASRS) incident data (1993 to 2008). Failure modes and effects analyses were examined to identify possible modes of SCFM. A table of potential adverse conditions was developed to help evaluate IVHM research technologies. Tables present details of specific SCFM for the incidents and accidents. Of the 370 NTSB accidents affected by SCFM, 48 percent involved the engine or fuel system, and 31 percent involved landing gear or hydraulic failure and malfunctions. A total of 35 percent of all SCFM accidents were caused by improper maintenance. Of the 7732 FAA database incidents affected by SCFM, 33 percent involved landing gear or hydraulics, and 33 percent involved the engine and fuel system. The most frequent SCFM found in ASRS were turbine engine, pressurization system, hydraulic main system, flight management system/flight management computer, and engine. Because the IVHM Project does not address maintenance issues, and landing gear and hydraulic systems accidents are usually not fatal, the focus of research should be those SCFMs that occur in the engine/fuel and flight control/structures systems as well as power systems.

  2. Adverse effects of beta-agonists: are they clinically relevant?

    Inhaled beta(2)-adrenoceptor agonists (beta(2)-agonists) are the most commonly used asthma medications in many Western countries. Minor adverse effects such as palpitations, tremor, headache and metabolic effects are predictable and dose related. Time series studies suggested an association between the relatively nonselective beta-agonist fenoterol and asthma deaths. Three case-control studies confirmed that among patients prescribed fenoterol, the risk of death was significantly elevated even after controlling for the severity of asthma. The Saskatchewan study not only found an increased risk of death among patients dispensed fenoterol, but also suggested this might be a class effect of beta(2)-agonists. However, in subsequent studies, the long-acting beta(2)-agonist salmeterol was not associated with increased asthma mortality. In a case-control study blood albuterol (salbutamol) concentrations were found to be 2.5 times higher among patients who died of asthma compared with controls. It is speculated that such toxic concentrations could cause tachyarrhythmias under conditions of hypoxia and hypokalemia. The risk of asthma exacerbations and near-fatal attacks may also be increased among patients dispensed fenoterol, but this association may be largely due to confounding by severity. Although salmeterol does not appear to increase the risk of near-fatal attacks, there is a consistent association with the use of nebulized beta(2)-agonists. Nebulized and oral beta(2)-agonists are also associated with an increased risk of cardiovascular death, ischemic heart disease and cardiac failure. Caution should be exercised when first prescribing a beta-agonist for patients with cardiovascular disease. A potential mechanism for adverse effects with regular use of beta(2)-agonists is tachyphylaxis. Tachyphylaxis to the bronchodilator effects of long-acting beta(2)-agonists can occur, but has been consistently demonstrated only for formoterol (eformoterol) a full agonist, rather

  4. Parenteral Lipid Tolerance and Adverse Effects: Fat Chance for Trouble?

    Wanten, Geert J A

    2015-09-01

    Lipid emulsions (LEs) are indispensable sources of fuel calories and (essential) fatty acids (FAs) in modern parenteral nutrition formulations. The use of LE, however, also remains associated with the development of adverse effects. Intolerance for LE mostly becomes apparent upon the development of patient complaints or disturbed blood function tests, mainly of the liver. These issues may be associated with the composition, stability, or the infusion rate of the emulsion. Also, altered balances of (anti)oxidants or the presence or absence of protective or toxic bioactive agents such as phytosterols and tocopherol in LE may lead to complications, especially in already vulnerable patients with an inflammatory condition. While the oldest available LEs are based on pure soybean oil (SO-LE), rich in the proinflammatory ω-6 polyunsaturated fatty acid linoleic acid, more recent next-generation LEs where alternative FA sources such as olive and fish oil (partially) replace soybean oil to lower the content of linoleic acid seem safe and effective. Especially LEs containing fish oil (FO-LE) have less proinflammatory characteristics that promise to convey beneficial effects on immune system and organ functions, although much of the available evidence awaits more robust clinical validation.

    Despite India's substantial progress in human development since its independence in 1947, 5-7% of its children have vitamin A deficiency disorders in selected geographic areas, 53% have iron deficiency anemia, and 9% have goiter. Three micronutrients--vitamin A, iron, and iodine--are among the most important of all the nutrients needed by the body because they are vital for developing normal learning and cognitive functions, immunity, work capacity, and reproductive health. The body cannot synthesize them, so they must be made available through the diet. Deficiencies of these three micronutrients are known to have devastating effects on health. PMID:12035866

    Full Text Available Exposure to childhood adversities (CA is associated with subsequent alterations in regional brain grey matter volume (GMV. Prior studies have focused mainly on severe neglect and maltreatment. The aim of this study was to determine in currently healthy adolescents if exposure to more common forms of CA results in reduced GMV. Effects on brain structure were investigated using voxel-based morphometry in a cross-sectional study of youth recruited from a population-based longitudinal cohort. 58 participants (mean age = 18.4 with (n = 27 or without (n = 31 CA exposure measured retrospectively from maternal interview were included in the study. Measures of recent negative life events (RNLE recorded at 14 and 17 years, current depressive symptoms, gender, participant/parental psychiatric history, current family functioning perception and 5-HTTLPR genotype were covariates in analyses. A multivariate analysis of adversities demonstrated a general association with a widespread distributed neural network consisting of cortical midline, lateral frontal, temporal, limbic, and cerebellar regions. Univariate analyses showed more specific associations between adversity measures and regional GMV: CA specifically demonstrated reduced vermis GMV and past psychiatric history with reduced medial temporal lobe volume. In contrast RNLE aged 14 was associated with increased lateral cerebellar and anterior cingulate GMV. We conclude that exposure to moderate levels of childhood adversities occurring during childhood and early adolescence exerts effects on the developing adolescent brain. Reducing exposure to adverse social environments during early life may optimize typical brain development and reduce subsequent mental health risks in adult life.

    The in vivo repeated dose toxicity (RDT) test is intended to provide information on the possible risk caused by repeated exposure to a substance over a limited period of time. The measure of the RDT is the no observed adverse effect level (NOAEL) that is the dose at which no effects are observed, i.e., this endpoint indicates the safety level for a substance. The need to replace in vivo tests, as required by some European Regulations (registration, evaluation authorization and restriction of chemicals) is leading to the searching for reliable alternative methods such as quantitative structure-activity relationships (QSAR). Considering the complexity of the RDT endpoint, for which data quality is limited and depends anyway on the study design, the development of QSAR for this endpoint is an attractive task. Starting from a dataset of 140 organic compounds with NOAEL values related to oral short term toxicity in rats, we developed a QSAR model based on optimal descriptors calculated with simplified molecular input-line entry systems and the graph of atomic orbitals by the Monte Carlo method, using CORAL software. Three different splits into the training, calibration, and validation sets are studied. The mechanistic interpretation of these models in terms of molecular fragment with positive or negative contributions to the endpoint is discussed. The probabilistic definition for the domain of applicability is suggested. PMID:25850638

  13. Second-Generation Antipsychotics and Extrapyramidal Adverse Effects

    Jakovcevski, Igor

    2014-01-01

    Antipsychotic-induced extrapyramidal adverse effects are well recognized in the context of first-generation antipsychotic drugs. However, the introduction of second-generation antipsychotics, with atypical mechanism of action, especially lower dopamine receptors affinity, was met with great expectations among clinicians regarding their potentially lower propensity to cause extrapyramidal syndrome. This review gives a brief summary of the recent literature relevant to second-generation antipsychotics and extrapyramidal syndrome. Numerous studies have examined the incidence and severity of extrapyramidal syndrome with first- and second-generation antipsychotics. The majority of these studies clearly indicate that extrapyramidal syndrome does occur with second-generation agents, though in lower rates in comparison with first generation. Risk factors are the choice of a particular second-generation agent (with clozapine carrying the lowest risk and risperidone the highest), high doses, history of previous extrapyramidal symptoms, and comorbidity. Also, in comparative studies, the choice of a first-generation comparator significantly influences the results. Extrapyramidal syndrome remains clinically important even in the era of second-generation antipsychotics. The incidence and severity of extrapyramidal syndrome differ amongst these antipsychotics, but the fact is that these drugs have not lived up to the expectation regarding their tolerability.

(no observed adverse effects level, NOAEL) and 1.35 mg kg(-1) b.wt. (1/100 lethal dose [LD(50)]) from postnatal day 1 until day 20 after delivery. At two high doses of CPF, the body weight gain and relative liver and kidney weight of suckling pups were significantly decreased. Exposure of the mothers to CPF caused increase in lipid peroxidation (LPO) and decrease in superoxide dismutase (SOD) and glutathione-s-transferase (GST) in lactating pups. CPF altered the level of the marker parameters related to the liver and kidneys. Consistent histological changes were found in the liver and kidneys of the subjected pups, especially at the higher doses. The results suggested that the transfer of CPF intoxication through the mother's milk has resulted in oxidative stress and biochemical and histopathological alterations in the suckling pups. The data of this study may be considered as a contribution to the problem of lactational transfer of the relatively less persistent OP pesticides, such as CPF. PMID:20028704

    The link between poverty and children's health is well recognized. Even temporary poverty may have an adverse effect on children's health, and data consistently support the observation that poverty in childhood continues to have a negative effect on health into adulthood. In addition to childhood morbidity being related to child poverty, epidemiologic studies have documented a mortality gradient for children aged 1 to 15 years (and adults), with poor children experiencing a higher mortality rate than children from higher-income families. The global great recession is only now very slowly abating for millions of America's children and their families. At this difficult time in the history of our nation's families and immediately after the 50th anniversary year of President Lyndon Johnson's War on Poverty, it is particularly germane for the American Academy of Pediatrics, which is "dedicated to the health of all children," to publish a research-supported technical report that examines the mediators associated with the long-recognized adverse effects of child poverty on children and their families. This technical report draws on research from a number of disciplines, including physiology, sociology, psychology, economics, and epidemiology, to describe the present state of knowledge regarding poverty's negative impact on children's health and development. Children inherit not only their parents' genes but also the family ecology and its social milieu. Thus, parenting skills, housing, neighborhood, schools, and other factors (eg, medical care) all have complex relations to each other and influence how each child's genetic canvas is expressed. Accompanying this technical report is a policy statement that describes specific actions that pediatricians and other child advocates can take to attenuate the negative effects of the mediators identified in this technical report and improve the well-being of our nation's children and their families.

    Full Text Available Abstract Background Mammary tumors are among the most frequent neoplasms in female dogs, but the strategies employed in animal treatment are limited. In human medicine, hormone manipulation is used in cancer therapy. Tamoxifen citrate is a selective inhibitor of oestrogen receptors and exerts a potent anti-oestrogen effect on the mammary gland. The aim of this study was to evaluate the adverse effects when exposing healthy female dogs to tamoxifen. Methods Tamoxifen was administered for 120 days at a dose of 0.5 or 0.8 mg/kg/day to either intact or spayed female dogs. The effects were assessed through clinical examination, haematology, serum biochemistry, ophthalmology and bone marrow aspirate examination. Ovariohysterectomy was performed and the uterus examined by histopathology. Results Vulva oedema and purulent vaginal discharge developed with 10 days of tamoxifen exposure in all groups. Pyometra was diagnosed after around 90 days of exposure in intact females with frequencies increasing during the following 30 days of exposure. Up to 50% of dogs within the groups developed retinitis but none of the dogs had signs of reduced visual acuity. The prevalence of retinitis in each group was similar after 120 days of exposure. Haematological, biochemical and bone marrow changes were not observed. Due to the high risk of developing pyometra after prolonged exposure to tamoxifen, only spayed animals should be given this medication. Conclusions A dose of 0.8 mg tamoxifen/kg body weight/day is recommended when treating tamoxifen-responsive canine mammary tumors. Due to the high risk of developing pyometra, ovariohysterectomy is recommended.

  17. Early-Life Adversity and Physical and Emotional Health Across the Lifespan: A Neuroimmune Network Hypothesis.

    2016-07-01

    Children who experience chronic stressors are vulnerable to emotional and physical health problems across the lifespan. This phenomenon raises questions for scientists and clinicians alike. How does adversity get under the skin of the developing child? Through what mechanisms does it confer vulnerability to a heterogeneous set of mental and physical illnesses? And how does it instantiate risk across different life stages, engendering vulnerability to conditions that develop shortly after stressor exposure-like depression-and conditions that manifest decades later, like heart disease? Although answers to these questions have started to emerge, research has typically focused on single diseases or organ systems. To understand the plethora of health problems associated with childhood adversity, we argue that the field needs a second generation of research that recognizes multidirectional transactions among biological systems. To help facilitate this process, we propose a neuroimmune network hypothesis as a heuristic framework for organizing knowledge from disparate literatures and as a springboard for generating integrative research. Drawing on existing data, we argue that early-life adversity amplifies crosstalk between peripheral inflammation and neural circuitries subserving threat-related, reward-related, and executive control-related processes. This crosstalk results in chronic low-grade inflammation, thereby contributing to adiposity, insulin resistance, and other predisease states. In the brain, inflammatory mediators act on cortico-amygdala threat and cortico-basal ganglia reward, circuitries in a manner that predisposes individuals to self-medicating behaviors like smoking, drug use, and consumption of high-fat diets. Acting in concert with inflammation, these behaviors accelerate the pathogenesis of emotional and physical health problems. PMID:26166230

    Diesel engine emissions are among the most prevalent anthropogenic pollutants worldwide, and with the growing popularity of diesel-fueled engines in the private transportation sector, they are becoming increasingly widespread in densely populated urban regions. However, a large number of toxicological studies clearly show that diesel engine emissions profoundly affect human health. Thus the interest in the molecular and cellular mechanisms underlying these effects is large, especially concerning the nature of the components of diesel exhaust responsible for the effects and how they could be eliminated from the exhaust. This review describes the fundamental properties of diesel exhaust as well as the human respiratory tract and concludes that adverse health effects of diesel exhaust not only emerge from its chemical composition, but also from the interplay between its physical properties, the physiological and cellular properties, and function of the human respiratory tract. Furthermore, the primary molecular and cellular mechanisms triggered by diesel exhaust exposure, as well as the fundamentals of the methods for toxicological testing of diesel exhaust toxicity, are described. The key aspects of adverse effects induced by diesel exhaust exposure described herein will be important for regulators to support or ban certain technologies or to legitimate incentives for the development of promising new technologies such as catalytic diesel particle filters.

    Debjani Das

    Full Text Available Most individuals successfully maintain psychological well-being even when exposed to trauma or adversity. Emotional resilience or the ability to thrive in the face of adversity is determined by complex interactions between genetic makeup, previous exposure to stress, personality, coping style, availability of social support, etc. Recent studies have demonstrated that childhood trauma diminishes resilience in adults and affects mental health. The Dopamine receptor D4 (DRD4 exon III variable number tandem repeat (VNTR polymorphism was reported to moderate the impact of adverse childhood environment on behaviour, mood and other health-related outcomes. In this study we investigated whether DRD4-exIII-VNTR genotype moderates the effect of childhood adversities (CA on resilience. In a representative population sample (n = 1148 aged 30-34 years, we observed an interactive effect of DRD4 genotype and CA (β = 0.132; p = 0.003 on resilience despite no main effect of the genotype when effects of age, gender and education were controlled for. The 7-repeat allele appears to protect against the adverse effect of CA since the decline in resilience associated with increased adversity was evident only in individuals without the 7-repeat allele. Resilience was also significantly associated with approach-/avoidance-related personality measures (behavioural inhibition/activation system; BIS/BAS measures and an interactive effect of DRD4-exIII-VNTR genotype and CA on BAS was observed. Hence it is possible that approach-related personality traits could be mediating the effect of the DRD4 gene and childhood environment interaction on resilience such that when stressors are present, the 7-repeat allele influences the development of personality in a way that provides protection against adverse outcomes.

    Full Text Available The paper analyzes a widely discussed problem of the negative health dynamics of the growing generation, and points out the necessity of complex consideration of all the factors adversely affecting children’s health. The special emphasis is on the fallowing harmful factors: intensification of training process; discrepancy between the applied training methods and techniques on the one side, and children’s age, sex and functional specifics and capabilities on the other side; shortcomings in organizing children’s physical activities; limitations of the expositive illustrative methods for developing the healthy lifestyle habits. The other group of factors is related to the teaching style and professional characteristics of the teachers. They include the common practice of «stress» tactics; incompetence in health saving technologies; personal indisposition and psychological drawbacks. The situation is exacerbated by the absence of psychologists and pediatricians in educational institutions. The multilevel approach to solving the problems of students’ health preservation and promotion involves the elicitation of objective, subjective, inschool and out-of-school health determining factors. The paper denotes the actual ways of children’s health preservation at the level of related ministries, departments, and educational institutions.

    Full Text Available OBJECTIVE: To estimate the extent to which exposure to music through earphones or headphones with MP3 players or at discotheques and pop/rock concerts exceeded current occupational safety standards for noise exposure, to examine the extent to which temporary and permanent hearing-related symptoms were reported, and to examine whether the experience of permanent symptoms was associated with adverse perceived general and mental health, symptoms of depression, and thoughts about suicide. METHODS: A total of 943 students in Dutch inner-city senior-secondary vocational schools completed questionnaires about their sociodemographics, music listening behaviors and health. Multiple logistic regression analyses were used to examine associations. RESULTS: About 60% exceeded safety standards for occupational noise exposure; about one third as a result of listening to MP3 players. About 10% of the participants experienced permanent hearing-related symptoms. Temporary hearing symptoms that occurred after using an MP3 player or going to a discotheque or pop/rock concert were associated with exposure to high-volume music. However, compared to participants not experiencing permanent hearing-related symptoms, those experiencing permanent symptoms were less often exposed to high volume music. Furthermore, they reported at least two times more often symptoms of depression, thoughts about suicide and adverse self-assessed general and mental health. CONCLUSIONS: Risky music-listening behaviors continue up to at least the age of 25 years. Permanent hearing-related symptoms are associated with people's health and wellbeing. Participants experiencing such symptoms appeared to have changed their behavior to be less risky. In order to induce behavior change before permanent and irreversible hearing-related symptoms occur, preventive measurements concerning hearing health are needed.

    The Risk of Crew Adverse Health Event Due to Altered Immune Response is identified by the National Aeronautics and Space Administration (NASA) Human Research Program (HRP) as a recognized risk to human health and performance in space. The HRP Program Requirements Document (PRD) defines these risks. This Evidence Report provides a summary of the evidence that has been used to identify and characterize this risk. It is known that human immune function is altered in- and post-flight, but it is unclear at present if such alterations lead to increased susceptibility to disease. Reactivation of latent viruses has been documented in crewmembers, although this reactivation has not been directly correlated with immune changes or with observed diseases. As described in this report, further research is required to better characterize the relationships between altered immune response and susceptibility to disease during and after spaceflight. This is particularly important for future deep-space exploration missions.

    During the past two decades, increasing recognition has been given to a relationship between oral health and systemic diseases. Associated systemic conditions include cardiovascular disease, diabetes, low birth weight and preterm births, respiratory diseases, rheumatoid arthritis, obesity, osteoporosis, and, in particular among oral conditions, periodontal disease. Low-grade inflammation is a common denominator linking these disorders. Applying an anecdotal approach and an integrative view, the medical and dental histories of two women document increasing ill health subsequent to incidences of maltreatment and sexual abuse, including oral penetration, at an early age. Comprehensive oral rehabilitation was required in both cases. These cases open for medical insight with regard to their implicit patho-physiology, when integrated with current evidence from neuroscience, endocrinology, and immunology, converging in the concepts of allostasis and allostatic load. In cases such as those presented in this paper, primary care physicians (family doctors, General Practitioners) and dentists may be the first to identify an etiological pattern. This report underlines the importance of increased and enhanced multidisciplinary research cooperation among health professionals. Our hypothesis is that childhood adversity may affect all aspects of human health, including adult oral health. PMID:25978926

    With the rapid growth of nanotechnology and future bulk manufacture of nanomaterials comes the need to determine, understand and counteract any adverse health effects of these materials that may occur during manufacture, during use, or accidentally. Nanotechnology is expanding rapidly and will affect many aspects of everyday life; there are already hundreds of products that utilize nanoparticles. Paradoxically, the unique properties that are being exploited (e.g. high surface reactivity and ability to cross cell membranes) might have negative health impacts. The rapid progress in development and use of nanomaterials is not yet matched by toxicological investigations. Epidemiological studies implicate the ultrafine (nano-sized) fraction of particulate air pollution in the exacerbation of cardiorespiratory disease and increased morbidity. Experimental animal studies suggest that the increased concentration of nanoparticles and higher reactive surface area per unit mass, alongside unique chemistry and functionality, is important in the acute inflammatory and chronic response. Some animal models have shown that nanoparticles which are deposited in one organ (e.g. lung and gut) may access the vasculature and target other organs (e.g. brain and liver). The exact relationship between the physicochemistry of a nanoparticle, its cellular reactivity, and its biological and systemic consequences cannot be predicted. It is important to understand such relationships to enjoy the benefits of nanotechnology without being exposed to the hazards. PMID:17511644

    Information related to adverse drug effects caused by ocular medications and ocular adverse effects of systemically administered drugs has increased over the last several decades. Here we review the medical literature over the last four decades to both quantitatively and qualitatively determine the adverse effects of ocular drugs and ocular toxicity of non-ocular drugs. A systematic bibliographic review of the literature was performed with the following terms: "drug treatment", "drug therapy", "ocular adverse effects", "ocular side effects", "ocular toxicity", "systemic side effects", "systemic adverse effects", "systemic toxicity", "ocular drug" and "ophthalmic drug" using the Boolean operators or, and, not. Searches focused on: (1) Ocular side/adverse effects of ophthalmic drugs; (2) Ocular side/adverse effects of systemic drugs; (3) Systemic side/adverse effects of ophthalmic drugs. PubMed was used to perform searches. Limits included: species, human and field tag, abstract/title, dates from 01/01/1971 to 31/12/2010. A sub-selection of references was made by discarding articles that were irrelevant for the topics listed above. Adverse effects of alpha2-adrenergic agonists, beta-adrenergic antagonists, quinine derivatives and antituberculosis agents appear in the literature throughout the period of the review. Adverse effects of newer drugs such as amiodarone, phosphodiesterase 5 inhibitors, antiepileptics, tamoxifen, and its interactions have been published principally in the last two decades. It is imperative for patient safety that knowledge of the adverse effects of drugs on the eye whether topically or systemically administered, and the possible systemic effects of drugs given as ophthalmic medications be emphasized to clinicians.

    Malnutrition and starvation's possible adverse impacts on bone health and bone quality first came into the spotlight after the horrors of the Holocaust and the ghettos of World War II. Famine and food restrictions led to a mean caloric intake of 200-800 calories a day in the ghettos and concentration camps, resulting in catabolysis and starvation of the inhabitants and prisoners. Severely increased risks of fracture, poor bone mineral density, and decreased cortical strength were noted in several case series and descriptive reports addressing the medical issues of these individuals. A severe effect of severely diminished food intake and frequently concomitant calcium- and Vitamin D deficiencies was subsequently proven in both animal models and the most common cause of starvation in developed countries is anorexia nervosa. This review attempts to summarize the literature available on the impact of the metabolic response to Starvation on overall bone health and bone quality. PMID:25810719

    Full Text Available BACKGROUND Acquired Immunodeficiency Syndrome, a disease of the human immune system caused by the Human Immunodeficiency Virus (HIV is a major health problem in many parts of the world. The prognosis was dramatically altered with the introduction of antiretroviral drugs in 1987 and Highly Active Antiretroviral Therapy (HAART in 1996. Despite the absence of a cure, the natural history of the disease was radically changed since then. This study aimed at documenting and analysing the adverse effect profile of Tenofovir Disoproxil Fumarate-based Antiretroviral Therapy (ART in HIV positive patients attending Antiretroviral Therapy Centre, Government Medical College, Thrissur. METHODOLOGY HIV positive patients on Tenofovir Disoproxil Fumarate-based antiretroviral treatment attending Antiretroviral Therapy Centre, Government Medical College, Thrissur, were enrolled in the prospective cohort study conducted over 18 months from Jan 2013- June 2014. The patients were followed up for 12 months pattern of adverse drug reactions. RESULTS A total of 178 Adverse Drug Reactions (ADRs were identified, out of which 86 (48.31% were in male and 92 (51.68% were in female patients. Out of 178 suspected ADRs, 172 (96.6% ADRs were reported from outpatient departments. Six patients (3.3% required hospital admission. The most commonly identified adverse drug reactions were nausea and vomiting in 54 (30.3% patients, headache and fatigue in 30 (16.85%, heartburn and diarrhoea in 17 (9.5% cases, lab abnormalities like dyslipidaemia in 12 (6.74%, hyperphosphatemia in 10 (5.6%, hypocalcemia in 5 (2.85% patients. Out of 178 ADRs, 4 (2.2% were of acute renal failure seen. One among the four died even after discontinuation of the drug, 2 were changed to non-Tenofovir based regimen who improved later within 2 months. CONCLUSION In this study of Tenofovir based regimen, the side effects which necessitated regimen change were very few. Majority of the side effects were GI related

We report herein a case of a 16-year-old Chinese boy with depression who experienced extrapyramidal-like effects, for example, facial spasm, upper limb dystonia, akathisia, and other disturbed behaviors, while being treated with sertraline 200 mg per day. His movement symptoms were significantly alleviated after the discontinuation of sertraline and the administration of scopolamine. This finding indicates that albeit infrequent, sertraline may cause severe extrapyramidal symptoms in adolescent patients, suggesting that clinicians should be alert to the neurological side effects of sertraline in young patients.

    Full Text Available Abstract Background Millions of veterans are eligible to use the Veterans Health Administration (VHA and Medicare because of their military service and age. This article examines whether an indirect measure of dual use based on inpatient services is associated with increased mortality risk. Methods Data on 1,566 self-responding men (weighted N = 1,522 from the Survey of Assets and Health Dynamics among the Oldest Old (AHEAD were linked to Medicare claims and the National Death Index. Dual use was indirectly indicated when the self-reported number of hospital episodes in the 12 months prior to baseline was greater than that observed in the Medicare claims. The independent association of dual use with mortality was estimated using proportional hazards regression. Results 96 (11% of the veterans were classified as dual users. 766 men (50.3% had died by December 31, 2002, including 64.9% of the dual users and 49.3% of all others, for an attributable mortality risk of 15.6% (p Conclusion An indirect measure of veterans' dual use of the VHA and Medicare systems, based on inpatient services, was associated with an increased risk of death. Further examination of dual use, especially in the outpatient setting, is needed, because dual inpatient and dual outpatient use may be different phenomena.

  18. Remembering Statins: Do Statins Have Adverse Cognitive Effects?

    Science.gov (United States)

    Bitzur, Rafael

    2016-08-01

    The issue of statin-associated cognitive impairment has been a hot topic among both patients and health care providers, especially since the U.S. Food and Drug Administration (FDA) issued a statement regarding rare postmarketing reports of ill-defined cognitive impairment associated with statin use. This statement was based on case reports, and no objective measures of cognitive function were used. Nevertheless, many patients at high risk of cardiovascular disease have expressed concerns about possible cognitive decline and may have opted to forgo statin therapy. In this overview, the evidence leading to the statement by the FDA is reviewed. Potential mechanisms of the effect of LDL cholesterol reduction and statin therapy on cognition are discussed. Evidence from observational and prospective randomized trials is summarized, leading to the conclusion that as for now, there is no good evidence that statins cause cognitive impairment to a significant degree. Reported cases seem to be rare, and a causal relationship has not been established. PMID:27440840

    Adverse childhood experiences (ACEs) have been linked with risky health behaviors and the development of chronic diseases in adulthood. This study examined associations between ACEs, chronic diseases, and risky behaviors in adults living in Riyadh, Saudi Arabia in 2012 using the ACE International Questionnaire (ACE-IQ). A cross-sectional design was used, and adults who were at least 18 years of age were eligible to participate. ACEs event scores were measured for neglect, household dysfunction, abuse (physical, sexual, and emotional), and peer and community violence. The ACE-IQ was supplemented with questions on risky health behaviors, chronic diseases, and mood. A total of 931 subjects completed the questionnaire (a completion rate of 88%); 57% of the sample was female, 90% was younger than 45 years, 86% had at least a college education, 80% were Saudi nationals, and 58% were married. One-third of the participants (32%) had been exposed to 4 or more ACEs, and 10%, 17%, and 23% had been exposed to 3, 2, or 1 ACEs respectively. Only 18% did not have an ACE. The prevalence of risky health behaviors ranged between 4% and 22%. The prevalence of self-reported chronic diseases ranged between 6% and 17%. Being exposed to 4 or more ACEs increased the risk of having chronic diseases by 2-11 fold, and increased risky health behaviors by 8-21 fold. The findings of this study will contribute to the planning and development of programs to prevent child maltreatment and to alleviate the burden of chronic diseases in adults. PMID:24974249

    In order to analyse the response of pharmaceutical companies to adverse drug reaction reports, 37 suspected side effects were sent by mail to the 30 companies concerned. The time period involved was 1 year and corresponded to a total of 3341 consultations in general practice. Companies answered in 29 cases (78.3%), sent 21 reply forms and returned 3 evaluations of adverse drugs reactions to the reporting doctor. The high percentage of adverse drug reactions (1.07 per one hundred consultations), the doctor's work-load and poor feed-back lead one to reflect on the usefulness of systematic adverse drug reaction reporting by general practitioners.

    Plants are of relevance to dermatology for both their adverse and beneficial effects on skin and skin disorders respectively. Virtually all cultures worldwide have relied historically, or continue to rely on medicinal plants for primary health care. Approximately one-third of all traditional medicines are for treatment of wounds or skin disorders, compared to only 1-3% of modern drugs. The use of such medicinal plant extracts for the treatment of skin disorders arguably has been based largely on historical/anecdotal evidence, since there has been relatively little data available in the scientific literature, particularly with regard to the efficacy of plant extracts in controlled clinical trials. In this article therefore, adverse and beneficial aspects of medicinal plants relating to skin and skin disorders have been reviewed, based on recently available information from the peer-reviewed scientific literature. Beneficial aspects of medicinal plants on skin include: healing of wounds and burn injuries (especially Aloe vera); antifungal, antiviral, antibacterial and acaricidal activity against skin infections such as acne, herpes and scabies (especially tea tree (Melaleuca alternifolia) oil); activity against inflammatory/immune disorders affecting skin (e.g. psoriasis); and anti-tumour promoting activity against skin cancer (identified using chemically-induced two-stage carcinogenesis in mice). Adverse effects of plants on skin reviewed include: irritant contact dermatitis caused mechanically (spines, irritant hairs) or by irritant chemicals in plant sap (especially members of the Ranunculaceae, Euphorbiaceae and Compositae plant families); phytophotodermatitis resulting from skin contamination by plants containing furocoumarins, and subsequent exposure to UV light (notably members of the Umbelliferae and Rutaceae plant families); and immediate (type I) or delayed hypersensitivity contact reactions mediated by the immune system in individuals sensitized to plants

    Herbal supplements have been used as adjuncts to medical therapy for many years by various cultures. Many consumers believe that because herbal supplements are natural products, they are somewhat safer or more effective than traditional prescribed medications. This is also one reason that alternative medicine is growing and gaining more popularity. On the other hand, adverse reactions to herbal supplements or their interactions with patients' current medications are no different than pharmaceutical medicines. We report a case of premature ventricular contraction associated with two herbal supplements. These products contained multiple different herbs and both included large doses of guarana. Guarana, which is found in some supplements marketed in U.S., contains a substantial amount of caffeine. Although the exact cause of tachycardia in our report is not proven, a large amount of caffeine consumption is thought to be a possible causal effect. The purpose of this report is to remind health care professionals to evaluate and educate patients on the use of herbal products and any potential adverse reactions, drug interactions, or possible toxicities.

The findings show that in rural South Africa, temporary migration has a major impact on household well-being and health. Remittances from migrants make a significant difference to socioeconomic status (SES in households left behind by the migrant. For the poorest households the key factors improving SES are government grants and female temporary migration, while for the less poor it is male temporary migration and local employment. Migration is associated with HIV but not in straightforward ways. Migrants that return more frequently may be less exposed to outside partners and therefore less implicated in the HIV epidemic. There are links between migration and mortality patterns, including a higher risk of dying for returnee migrants compared with permanent residents. A mother's migration impacts significantly on child survival for South African and former refugee parents, but there is an additional mortality risk for children of Mozambican former refugees. It is recommended that national censuses and surveys account for temporary migration when collecting information on household membership, because different migration types have different outcomes. Without discriminating between different migration types, the implications for sending and receiving communities will remain lost to policy-makers.

    Full Text Available Abstract Background To estimate the occurrence and type of adverse effects after application of an extra-articular (soft tissue corticosteroid injection. Methods A systematic review of the literature was made based on a PubMed and Embase search covering the period 1956 to January 2010. Case reports were included, as were prospective and retrospective studies that reported adverse events of corticosteroid injection. All clinical trials which used extra-articular corticosteroid injections were examined. We divided the reported adverse events into major (defined as those needing intervention or not disappearing and minor ones (transient, not requiring intervention. Results The search yielded 87 relevant studies:44 case reports, 37 prospective studies and 6 retrospective studies. The major adverse events included osteomyelitis and protothecosis; one fatal necrotizing fasciitis; cellulitis and ecchymosis; tendon ruptures; atrophy of the plantar fat was described after injecting a neuroma; and local skin effects appeared as atrophy, hypopigmentation or as skin defect. The minor adverse events effects ranged from skin rash to flushing and disturbed menstrual pattern. Increased pain or steroid flare after injection was reported in 19 studies. After extra-articular injection, the incidence of major adverse events ranged from 0-5.8% and that of minor adverse events from 0-81%. It was not feasible to pool the risk for adverse effects due to heterogeneity of study populations and difference in interventions and variance in reporting. Conclusion In this literature review it was difficult to accurately quantify the incidence of adverse effects after extra-articular corticosteroid injection. The reported adverse events were relatively mild, although one fatal reaction was reported.

    Full Text Available Background. This study aims to share our experiences when carrying out observational studies of traditional Chinese medicine (TCM. Methods. We have proactively monitored the safety profiles of Duhuo Jisheng Tang (DJT, Suan Zao Ren Tang (SZRT, and TMN-1. A list of adverse events (AEs, complete blood counts, and liver and kidney function tests were obtained from the participants during their scheduled hospital visits. Retrospective observational studies were conducted based on the reimbursement database of the National Health Insurance system, Taiwan, to explore the relationship between the use of TCM that have been adulterated by aristolochic acid and the risk from both nephrotoxins and carcinogens. Results. A total of 221, 287, and 203 AEs were detected after SZRT, DJT, and TMN-1 had been taken, respectively. Dizziness, headache, stomach ache, and diarrhea were judged to be probably related to SZRT treatment. Retrospective observational studies found an association between the consumption of aristolochic acid-containing Chinese formulae such as Mu Tong and an increased risk of CKD, ESRD, and urinary tract cancer. Conclusion. Prospective and retrospective observational studies seem to have specific advantages when investigating the safety and adverse effects of TCM therapies, as well as possibly other alternative/complementary therapies.

    The assessment procedure of new synthetic illicit drugs that are not documented in the UN treaty on psychotropic drugs was evaluated using a modified Electre model. Drugs were evaluated by an expert panel via the open Delphi approach, where the written score was discussed on 16 items, covering medical, health, legal, and criminalistic issues of the drugs. After this face-to-face discussion the drugs were scored again. Taking the assessment of ketamine as an example, it appeared that each expert used its own scale to score, and that policymakers do not score deviant from experts trained in the medical-biological field. Of the five drugs evaluated by the panel, p-methoxy-metamphetamine (PMMA), gamma-hydroxybutyric acid (GHB), and 4-methylthio-amphetamine (MTA) were assessed as more adverse than ketamine and psilocine and psilocybine-containing mushrooms. Whereas some experts slightly adjusted during the assessment procedure their opinion on ketamine and PMMA, the opinion on mushrooms was not affected by the discussion held between the two scoring rounds. All experts rank the five drugs in a similar way on the adverse effect scale i.e., concordance scale of the Electre model, indicating unanimity in the expert panel with respect to the risk classification of these abused drugs.

    2013-01-01

    Little is known about the health impact of air pollution on children's cardiovascular health. A cross-sectional study was conducted and data was analysed in 2048 Chinese schoolchildren (aged 8-10 years) in three districts of Hong Kong to examine the association between exposure to outdoor air pollution and cardiorespiratory fitness. Annual means of ambient PM10, SO2, NO2 and O3 from 1996 to 2003 were used to estimate individual exposure of the subjects. Cardiorespiratory fitness was measured for maximal oxygen uptake (VO2max), predicted by the multistage fitness test (MFT). Height and weight were measured and other potential confounders were collected with questionnaires. Analysis of covariance was performed to estimate the impact of air pollution on complete speed in the MFT and predicted VO2max. The results showed that children in high-pollution district had significantly lower complete speed and predicted VO2max compared to those in low- and moderate-pollution districts. Complete speed and predicted VO2max was estimated to reduce 0.327 km h-1 and 1.53 ml kg-1 min-1 per 10 μg m-3 increase in PM10 annual mean respectively, with those in girls being greater than in boys. Being physically active could not significantly result in improved cardiorespiratory fitness in polluted districts. The adverse effect seems to be independent of short-term exposure to air pollution. We concluded that long-term exposure to higher outdoor air pollution levels was negatively associated with cardiorespiratory fitness in Chinese schoolchildren, especially for girls. PM10 is the most relevant pollutant of the adverse effect. Elevated cardiorespiratory fitness observed in physically activate children could be negated by increased amount of inhaled pollutants during exercise.

    Full Text Available Background: Participation in social networking is commonplace and social media is transforming both health and health related research. Of the various social media platforms, Twitter must be considered a platform for rapid and immediate communication. There has been considerable national and international media coverage reporting a number of adverse incidents in the Irish maternity services. The media coverage of these adverse incidents, most recently about a cluster of perinatal deaths, stimulated much public debate including debate online. Aim: Our study aimed to explore the Twitter status updates, and subsequent responses, relating to a number of perinatal deaths which occurred in a maternity unit with approximately 2,000 births per year. Method: As this study examined Twitter status updates in relation to reported perinatal death a mixed methods approach was adopted. Firstly, status updates in English were searched utilising the Twitter search function on its website. A search was undertaken on all public status updates from January 29th 2014 to March 31st 2014 relating to the perinatal deaths. Data were quantitatively analysed in order to assess the frequency of status updates, the demographic profiles of users and to ascertain the potential reach of the status updates. Secondly qualitative analysis was employed to generate themes from the content that twitter users shared publically. Results: From January 29th 2014 to March 31st 2014, 3,577 Twitter status updates from 1,276 profiles relating to the perinatal deaths were identified. Of these, 54.1% (n=1615 were tweets, 38.9% (n=1392 were retweets and 15.9% (n=570 were replies. Over one third of all updates (36.8%; n=1317 were from profiles which identified the user as either a media outlet or media personnel. One in 10 (11.8%; 424 status updates were by those who self-identified as a parent. Twitter was not utilised as a platform by any healthcare authority to release a statement in

    2016-07-01

    There is increasing evidence supporting the existence of a link between income inequalities and health outcomes. The main purpose of this article is to test whether economic inequalities are associated with poor population health in Latin American countries. Multi-country data from 1970 to 2012 were used to assess this question. The results show that the Gini coefficient has a strong correlation with health outcomes. Moreover, multiple linear regression analysis using fixed effects shows that after controlling for gross national income per capita, literacy rate, and health expenditure, the Gini coefficient is independently negatively associated with health outcomes. In Latin American countries, for every percentage point increase in the Gini coefficient, the infant mortality rate grows by 0.467 deaths per 1,000 live births, holding all other variables constant. Additionally, an ordinary least squares estimation model suggests that countries that do not use International Monetary Fund loans perform better on health outcomes. These findings should alert policymakers, elected officials, and the public of the need to fight income inequalities and rethink the role of international financial institutions that dictate state policies.

    Recently,novel anti-androgens and inhibitors of androgen biosynthesis have been developed through the elucidation of mechanisms of castration resistance of prostate cancer.We believe that these new developments will improve hormonal therapy.On the other hand,there has been an increase in criticism of hormonal therapy,because hormonal therapy is supposed to induce adverse effects such as cardiovascular disease.In this review,we have introduced the Japanese experience of hormonal therapy,because we believe that there may be ethnic differences between Caucasians and Asian people in the efficacy and adverse effects of hormonal therapy.First,we showed that primary hormonal therapy can achieve long-term control of localized prostate cancer in some cases and that quality of life of patients receiving hormonal therapy is rather better than previously thought.Neoadjuvant and adjuvant hormonal therapy in cases undergoing radical prostatectomy or radiotherapy are very useful for high-risk or locally advanced prostate cancer.Further clinical trials are required to confirm the efficacy of neoadjuvant or adjuvant hormonal therapy.We showed that the death from cardiovascular diseases in Japanese patients receiving hormonal therapy was not higher than that in the general population.However,efforts should be made to decrease the adverse effects of hormonal therapy,because life-style change may increase the susceptibility to adverse effects by hormonal therapy even in Japan.Managements of endocrine and metabolic dysfunction,such as diabetes mellitus,are essential.New hormonal compounds such as selective androgen receptor modulators capable of specifically targeting prostate cancer are expected to be developed.

    Purpose. The use of radiation therapy (RT) together with improvement in the surgical treatment of rectal cancer improves survival and reduces the risk for local recurrences. Despite these benefits, the adverse effects of radiation therapy limit its use. The aim of this review was to present a comprehensive overview of published studies on late adverse effects related to the RT for rectal cancer. Methods. Meta-analyses, reviews, randomised clinical trials, cohort studies and case-control studies on late adverse effects, due to pre- or postoperative radiation therapy and chemo-radiotherapy for rectal cancer, were systematically searched. Most information was obtained from the randomised trials, especially those comparing preoperative short-course 5x5 Gy radiation therapy with surgery alone. Results. The late adverse effects due to RT were bowel obstructions; bowel dysfunction presented as faecal incontinence to gas, loose or solid stools, evacuation problems or urgency; and sexual dysfunction. However, fewer late adverse effects were reported in recent studies, which generally used smaller irradiated volumes and better irradiation techniques; although, one study revealed an increased risk for secondary cancers in irradiated patients. Conclusions. These results stress the importance of careful patient selection for RT for rectal cancer. Improvements in the radiation technique should further be developed and the long-term follow-up of the randomised trials is the most important source of information on late adverse effects and should therefore be continued.

Hip and vertebral fractures might impair mobility, and vertebral fractures further reduce lung function. This review discusses the evidence of bone loss due to medical treatment opposed to disease severity and risk factors for COPD, and therapeutic options for the prevention and treatment of osteoporosis in these patients. A review of the English-language literature was conducted using the MEDLINE database until June 2009. Currently used bronchodilators probably lack adverse effect on bone. Oral corticosteroids (OCS increase bone resorption and decrease bone formation in a dose response relationship, but the fracture risk is increased more than reflected by bone densitometry. Inhaled corticosteroids (ICS have been associated with both increased bone loss and fracture risk. This might be a result of confounding by disease severity, but high doses of ICS have similar effects as equipotent doses of OCS. The life-style factors should be modified, use of regular OCS avoided and use of ICS restricted to those with evidenced effect and probably kept at moderate doses. The health care should actively reveal risk factors, include bone densitometry in fracture risk evaluation, and give adequate prevention and treatment for osteoporosis.Keywords: COPD, corticosteroids, bronchodilators, bone mineral density, osteoporosis, fractures

  6. Concrete blocks' adverse effects on indoor air and recommended solutions

    International Nuclear Information System (INIS)

    Air infiltration through highly permeable concrete blocks can allow entry of various serious indoor air pollutants including radon. An easy approach to avoiding these pollutants is to select a less-air-permeable concrete block. Tests show that air permeability of concrete blocks can vary by a factor greater than 50 (0.63--35 standard L/min/m2 at 3 Pa). The surface texture of the blocks correlates well with air permeability; test results of smoother, closed-surface-texture blocks were usually less air-permeable. During construction, air infiltration can be minimized by capping walls and carefully sealing around openings for utilities or other penetrations. Structures with indoor air-quality problems due to soil-gas entry can be mitigated more effectively with less coating material if the blocks have a closed surface texture. All coatings evaluated--cementaceous block filler (which has the lowest applied cost and is more than 99.5% effective), surface bonding cement, water-based epoxy, polysulfide vinyl acrylic, and latex (three coats)--were highly effective (more than 98%) in reducing air permeability when adequately applied. Coating selection should be influenced by expected service life, considering surface condition and cost

    Recent years have seen a rapidly increasing trend towards the delivery of health technology through mobile devices. Smartphones and tablet devices are thus becoming increasingly popular for accessing information and a wide range of services, including health care services. Modern mobile apps can be used for a variety of reasons, ranging from education for the patients and assistance to clinicians to delivery of interventions. Mobile phone apps have also been established to benefit patients in a scope of interventions across numerous medical specialties and treatment modalities. Medical apps have their advantages and disadvantages. It is important that clinicians have access to knowledge to make decisions regarding the use of medical apps on the basis of risk-benefit ratio. Mobile apps that deliver psycho social interventions offer unique challenges and opportunities. A number of reviews have highlighted the potential use of such apps. There is a need to describe, report and study their side effects too. The adverse effects associated with these apps can broadly be divided into: (1) those resulting from the security and safety concerns; (2) those arising from the use of a particular psycho social intervention; and (3) those due to the interaction with digital technology. There is a need to refine and reconsider the safety and adverse effects in this area. The safety profile of a mobile PSI app should describe its safety profile in: (1) privacy and security; (2) adverse effects of psychotherapy; and (3) adverse effects unique to the use of apps and the internet. This is, however, a very new area and further research and reporting is required to inform clinical decision making. PMID:27354959

  10. The Adverse Effects of Alcohol on Vitamin A Metabolism

    Directory of Open Access Journals (Sweden)

    William S. Blaner

    2012-05-01

    Full Text Available The objective of this review is to explore the relationship between alcohol and the metabolism of the essential micronutrient, vitamin A; as well as the impact this interaction has on alcohol-induced disease in adults. Depleted hepatic vitamin A content has been reported in human alcoholics, an observation that has been confirmed in animal models of chronic alcohol consumption. Indeed, alcohol consumption has been associated with declines in hepatic levels of retinol (vitamin A, as well as retinyl ester and retinoic acid; collectively referred to as retinoids. Through the use of animal models, the complex interplay between alcohol metabolism and vitamin A homeostasis has been studied; the reviewed research supports the notion that chronic alcohol consumption precipitates a decline in hepatic retinoid levels through increased breakdown, as well as increased export to extra-hepatic tissues. While the precise biochemical mechanisms governing alcohol’s effect remain to be elucidated, its profound effect on hepatic retinoid status is irrefutable. In addition to a review of the literature related to studies on tissue retinoid levels and the metabolic interactions between alcohol and retinoids, the significance of altered hepatic retinoid metabolism in the context of alcoholic liver disease is also considered.

    Long-term antidepressant treatment has increased and there is evidence of adverse effects; however, little is known about patients’ experiences and views of this form of treatment. This study used mixed methods to examine patients’ views and experiences of long-term antidepressant treatment, including benefits and concerns. Data from 180 patients, who were long-term users of antidepressants (3–15 years), were extracted from an anonymous online survey of patients’ experiences of antidepressants in New Zealand. Participants had completed rating scales about the effectiveness of antidepressants, levels of depression before and during antidepressant use, quality of life, and perceived adverse effects. Two open-ended questions allowed participants to comment on personal experiences. The majority (89.4%) reported that antidepressants had improved their depression although 30% reported moderate-to-severe depression on antidepressants. Common adverse effects included withdrawal effects (73.5%), sexual problems (71.8%), and weight gain (65.3%). Adverse emotional effects, such as feeling emotionally numb (64.5%) and addicted (43%), were also common. While the majority of patients were pleased with the benefits of antidepressant treatment, many were concerned about these adverse effects. Some expressed a need for more information about long-term risks and increased information and support to discontinue. PMID:27528803

    2016-01-01

    There is a growing body of epidemiological research reporting the neurological effects of ambient air pollution. We examined current evidence, identified the strengths and weaknesses of published epidemiological studies, and suggest future directions for research in this area. Studies were identified through a systematic search of online scientific databases, in addition to a manual search of the reference lists from the identified papers. Despite being a relatively new area of investigation, overall, there is mounting evidence implicating adverse effects of air pollution on neurobehavioral function in both adults and children. Further research is needed to expand our understanding of these relationships, including improvement in the accuracy of exposure assessments; focusing on specific toxicants and their relationships to specific health endpoints, such as neurodevelopmental disorders and neurodegenerative diseases; investigating the combined neurological effects of multiple air pollutants; and further exploration of genetic susceptibility for neurotoxicity of air pollution. In order to achieve these goals collaborative efforts are needed from multidisciplinary teams, including experts in toxicology, biostatistics, geographical science, epidemiology, and neurology.

    Full Text Available This study aims to determine the effects of the automotive industry on carbon dioxide emissions for the period from 1997 to 2010 for diverse economies, as well as the relationships between carbon dioxide discharges and output. The study applies cointegration and causality tests to validate these associations. The results of the Johansen cointegration test depict long-run associations between the quantity of passenger cars and carbon dioxide emissions in France, Sweden, Spain, Hungary and Japan. In addition, significant relations were observed between output and carbon dioxide discharges in Spain, Canada, India and Japan. Changes in output had substantial impact on emissions in Germany, Canada and India. The results also show that the number of passenger cars influences the magnitude of emissions in multiple economies. In conclusion, the automotive industry has to be considered in policies that aim to reduce carbon dioxide emissions.

    The fluoroquinolones have been extensively used in the neutropenic patient. When fluoroquinolone monotherapy was used as prophylaxis, frequently for extended periods, the rate of adverse effect of ciprofloxacin (6.9%) ofloxacin (11.6%) and norfloxacin (5.5%) were significantly lower than those of the comparator agents--co-trimoxazole, vancomycin and polymycin. Rash and gastrointestinal upset were the commonest adverse effects associated with the fluoroquinolones. When used as monotherapy for bacterial infections, often intravenously and in high dosages, the cumulative rate of adverse effects caused by the fluoroquinolones (12.6%) was similar to that caused by the comparator agents (10.3%), but significantly higher than reported for non-neutropenic patients (6.4%) and for prophylactic use. The main adverse events were also rashes (15.4%) and gastrointestinal upset (6.1%). When fluoroquinolones were used as therapy of bacterial infections in combination with other agents, the incidence of adverse events was 14.9%, which was similar to the comparator agents (13.5%). Adverse events were also similar except that nephrotoxicity was commonest with comparator combinations (4.0%). The data suggest that fluoroquinolone prophylaxis in neutropenic patients, even for prolonged periods, is safer than the comparator agents, but is associated with more frequent adverse events than in non-neutropenic patients. Fluoroquinolone therapy, frequently with high dosages, is associated with similar rate of adverse events as the comparator agents. When used in combination with the other antibiotics, fluoroquinolones are as safe as the comparator agents. PMID:7961217

    Full Text Available We studied the effects of advanced glycation end products (AGEs, which are known to accumulate in patients with diabetes, autoimmune diseases, or those who smoke, on embryonal development. Pronuclear (PN embryos were obtained by flushing the fallopian tubes of rats after superovulation and mating. The cleavage rate and blastocyst yield were evaluated at 24, 72, 96, and 120 h of culture. Glyoxal, an AGE-forming aldehyde, suppressed embryonal development at every stage from PN to blastocyst in a concentration-dependent manner. The cleavage rate of the embryo was also signifi cantly decreased by treatment with glyoxal at concentrations of 1 mM or higher. The blastocyst yield was significantly decreased by treatment with glyoxal at concentrations of 0.5 mM or higher. N-acetyl-L-cysteine (L-NAC at 1 mM significantly suppressed the glyoxal-induced embryonal toxicity. BSA-AGEs at 5 microg/ml or higher concentration signifi cantly reduced the cleavage rate and blastocyst yield compared to those for BSA-treated embryos. L-NAC at 1 mM significantly suppressed BSAAGE-induced embryonal toxicity. Because AGEs are embryo-toxic, AGE contamination may influence the pregnancy rate of in vitro fertilization and embryo transfer. AGEs, which are increased in women under pathological conditions, may also be involved in their infertility.

    2013-01-01

    Full Text Available Abstract Background Post-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access. Methods We conducted 4 semi-structured focus groups comprising altogether 28 Japanese gynecological cancer survivors to collect a variety of participants’ post-treatment care-seeking behaviors through active interaction with participants. Factors influencing access to treatment for adverse effects were analyzed qualitatively. Results Survivors sought care through specialty clinic visits when regular post-treatment gynecological follow-ups were inadequate or when symptoms seemed to be non-treatment related. Information provided by hospital staff during initial treatment influenced patients’ understanding and response to adverse effects. Lack of knowledge and inaccurate symptom interpretation delayed help-seeking, exacerbating symptoms. Gynecologists’ attitudes during follow-ups frequently led survivors to cope with symptoms on their own. Information from mass media, Internet, and support groups helped patients understand symptoms and facilitated care seeking. Conclusions Post-treatment adverse effects are often untreated during follow-up visits. Awareness of possible post-treatment adverse effects is important for gynecological cancer survivors in order to obtain appropriate care if the need arises. Consultation during the follow-up visit is essential for continuity in care.

  20. Radiation protection and health effects

    International Nuclear Information System (INIS)

    The use of ionizing radiation in nuclear medicine carries with it a responsibility to both patient and personnel to maximize the diagnostic and therapeutic benefit while minimizing the potential for any adverse health effects. Shortly after the discovery of the x-ray in 1895 the potential for acute health hazards of ionizing radiation became apparent. However, the risks of ionizing radiation were poorly understood and many early users did not believe that anyone could be hurt by something that could not be detected by any of the human senses. Many experiments on the biologic effects of ionizing radiation began in the early 1900s, and the first radiation protection standards were proposed by the British Roentgen Society in 1915. We now realize that these pioneers had a very limited knowledge of the potential hazards and radiation protection principles. Today more scientific data are available on the health effects of, detection of, and protection from ionizing radiation than any other physical agent or chemical known. In addition, use of many forms of ionizing radiation is heavily regulated at both national and state levels. This paper discusses how maternal contamination with radionuclides may cause irradiation of the fetus even if the radionuclide is not transferred across the placenta. This is mostly true for radionuclides that decay yielding relatively penetrating radiations

    Full Text Available Finasteride is a 5α-reductase inhibitor widely used in present in the therapeutic approach of androgenic alopecia. Adverse effects consist in variable sign and symptoms, the most common being represented by mental troubles (reduced feeling of life pleasure or emotions, depression, physical impairments (loss of muscle tone and/or mass and sexual complains (loss of libido and sexual potency. An increasing number of studies identify and describe even a post-finasteride syndrome (persistent adverse affects three months or more after finasteride cessation or new adverse effects including but not limited at the skin level or oral cavity (marginal periodontium. We intend to present in this study several oral adverse effects encountered during finasteride administration, represented by mild and moderate signs which generally responded to topical procedures without to require the stop of the drug administration. New studies on large samples will further document the existing relation between the described oral adverse effects and the implied pathophysiological mechanisms. For this moment, we are taking into account as possible mechanisms- a direct action of finasteride administration, possible indirect consequences due to hormonal interferences, or coexisting factors with finasteride administration that were not detected.

Scopus, Google Scholar, ClinicalTrials.gov, the ISRCTN registry as well as reference lists of the trials included and relevant reviews were manually searched.Study selectionRandomised (RCTs) and prospective non-randomised clinical trials (non-RCTs) on human patients that compared therapeutic and adverse effects of lingual and labial appliances were considered. One reviewer initially screened titles and subsequently two reviewers independently screened the selected abstracts and full texts.Data extraction and synthesisThe data were extracted independently by the reviewers. Missing or unclear information, ongoing trials and raw data from split-mouth trials were requested from the authors of the trials. The quality of the included trials and potential bias across studies were assessed using Cochrane's risk of bias tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. For parallel trials, mean difference (MD) and the relative risk (RR) were used for continuous (objective speech performance, subjective speech performance, intercanine width, intermolar width and sagittal anchorage loss) and binary outcomes (eating difficulty), respectively. The standardised mean difference (SMD) was chosen to pool, after conversion, the outcome (oral discomfort) that assessed both binary and continuous. Random-effects meta-analyses were conducted, followed by subgroup and sensitivity analyses.ResultsThirteen papers pertaining to 11 clinical trials (three parallel RCTs, one split-mouth RCT and seven parallel prospective non-RCTs) were included with a total of 407 (34% male/66% female) patients. All trials had at least one bias domain at high risk of bias. Compared with labial appliances

    Chemical prroducts used in farming and wastes from livestock can contaminate pond water in agroecosystems due to runoff. Amphibians using these ponds for breeding are probably exposed to pollutants, and serious consequences might be observed afterward at the population level. Assessment biological endpoints of anuran to water quality give a realistic estimate of the probability of occurrence of adverse effects and provide an early warning signal. In this study, the ecotoxicity of agroecosystem ponds from the south of Córdoba province, Argentina, was investigated. Ponds in four sites with different degrees of human disturbance were selected: three agroecosystems (A1, A2, A3) and a site without crops or livestock (SM). The effect of pond water quality on the biological endpoint of Rhinella arenarum tadpoles was examined using microcosms with pond water from sites. Biological endpoints assessed were as follows: mortality, growth, development, morphological abnormalities (in body shape, gut, and labial tooth row formula), behavior, and blood cell parameters (micronucleus and nuclear abnormalities). Results indicated that water from agroecosystems has adverse effect on early life stage of R. arenarum. High mortality and fewer metamorphs were recorded in the A1 and A3 treatments. Tadpoles and metamorphs from A1 and A2 treatments had lower body condition. Tadpoles from A1 and A3 showed the highest prevalence of morphological abnormalities. The lowest amount of tadpoles feeding and the highest percentage of tadpoles swimming on the surface were observed in treatments with agroecosystem pond water. The higher frequencies of micronuclei and nuclear abnormalities were recorded in tadpoles from A1, A2, and A3 treatments. We check the sensitivity of the biological endpoints of R. arenarum tadpoles like early warning indicators of water quality. We found that the poor water quality of agroecosystem ponds has impact on the health of the tadpoles, and this could affect the

    Full Text Available Long-term intravenous immunoglobulin (IVIG infusion is an effective treatment for children with humoral immunodeficiencies, already be complicated by systemic ad¬verse effects. In order to determine the adverse effects of intravenous immunoglobulin inpatients with antibody deficiency, 45 immunodeficientpatients receiving intravenous immunoglobulin were studied during a 36-month period at Children's Medical Center. The investigated group included 25 patients with common variable immunodeficiency, 14 patients with X-linked agammaglobulinemia and 6 patients with IgG subclass defi¬ciency. A total of fifty adverse effects occurred through 955 infusions (5.2%. The most frequent immediate adverse effects were mild (40 infusions out of 955 in 22 cases, including: chills, flushing, fever, nausea and headache. Three patients experienced mod¬erate effects (10 infusions out of 955 such as rash, severe headache, joint pain and chest tightness. None of the effects was anaphylactic type. It can be concluded that intravenous immunoglobulin is generally a well-tolerated medical agent for patients with antibody deficiency, but all patients should be monitored by a physician who is familiar with its indications, risks, adverse effects and their appropriate management.

    Malnutrition and starvation's possible adverse impacts on bone health and bone quality first came into the spotlight after the horrors of the Holocaust and the ghettos of World War II. Famine and food restrictions led to a mean caloric intake of 200–800 calories a day in the ghettos and concentration camps, resulting in catabolysis and starvation of the inhabitants and prisoners. Severely increased risks of fracture, poor bone mineral density, and decreased cortical strength were noted in sev...

    This article examines the possible adverse effects of well-intended climate policies. A weak Green Paradox arises if the announcement of a future carbon tax or a sufficiently fast rising carbon tax encourages fossil fuel owners to extract reserves more aggressively, thus exacerbating global warming. We argue that such policies may also encourage more fossil fuel to be locked in the crust of the earth, which can offset the adverse effects of the weak Green Paradox. We show that a subsidy on cl...

  13. Iohexol and iopamidol myelography in the dog: a clinical trial comparing adverse effects and myelographic quality

    International Nuclear Information System (INIS)

    In a blind clinical trial, adverse effects after iohexol and iopamidol myelography were evaluated in 151 dogs. Eighty-one dogs were given iohexol (240 mgI/ml) and 70 dogs were given iopamidol (200 mgI/ml) by pre-determined assignment. Each dog was evaluated postmyelographically for seizures, hyperthermia, prolonged recovery from anesthesia and intensification of pre-existing neural signs. Myelographic quality was evaluated with a subjective scoring method. In comparing iohexol and iopamidol groups, there was not a statistically significant difference in the incidence of adverse effects or in myelographic quality. Iopamidol and iohexol appeared to be equally efficacious for routine canine myelography

  14. Pretreatment Predictors of Adverse Radiation Effects After Radiosurgery for Arteriovenous Malformation

    International Nuclear Information System (INIS)

    Purpose: To identify vascular and dosimetric predictors of symptomatic T2 signal change and adverse radiation effects after radiosurgery for arteriovenous malformation, in order to define and validate preexisting risk models. Methods and Materials: A total of 125 patients with arteriovenous malformations (AVM) were treated at our institution between 2005 and 2009. Eighty-five patients have at least 12 months of clinical and radiological follow-up. Any new-onset headaches, new or worsening seizures, or neurological deficit were considered adverse events. Follow-up magnetic resonance images were assessed for new onset T2 signal change and the volume calculated. Pretreatment characteristics and dosimetric variables were analyzed to identify predictors of adverse radiation effects. Results: There were 19 children and 66 adults in the study cohort, with a mean age of 34 (range 6–74). Twenty-three (27%) patients suffered adverse radiation effects (ARE), 9 patients with permanent neurological deficit (10.6%). Of these, 5 developed fixed visual field deficits. Target volume and 12 Gy volume were the most significant predictors of adverse radiation effects on univariate analysis (p 3, above which the rate of ARE increased dramatically. Multivariate analysis target volume and the absence of prior hemorrhage are the only significant predictors of ARE. The volume of T2 signal change correlates to ARE, but only target volume is predictive of a higher volume of T2 signal change. Conclusions: Target volume and the absence of prior hemorrhage is the most accurate predictor of adverse radiation effects and complications after radiosurgery for AVMs. A high percentage of permanent visual field defects in this series suggest the optic radiation is a critical radiosensitive structure.

    Unconventional oil and gas operations using hydraulic fracturing can contaminate surface and groundwater with endocrine-disrupting chemicals. We have previously shown that 23 of 24 commonly used hydraulic fracturing chemicals can activate or inhibit the estrogen, androgen, glucocorticoid, progesterone, and/or thyroid receptors in a human endometrial cancer cell reporter gene assay and that mixtures can behave synergistically, additively, or antagonistically on these receptors. In the current study, pregnant female C57Bl/6 dams were exposed to a mixture of 23 commonly used unconventional oil and gas chemicals at approximately 3, 30, 300, and 3000 μg/kg·d, flutamide at 50 mg/kg·d, or a 0.2% ethanol control vehicle via their drinking water from gestational day 11 through birth. This prenatal exposure to oil and gas operation chemicals suppressed pituitary hormone concentrations across experimental groups (prolactin, LH, FSH, and others), increased body weights, altered uterine and ovary weights, increased heart weights and collagen deposition, disrupted folliculogenesis, and other adverse health effects. This work suggests potential adverse developmental and reproductive health outcomes in humans and animals exposed to these oil and gas operation chemicals, with adverse outcomes observed even in the lowest dose group tested, equivalent to concentrations reported in drinking water sources. These endpoints suggest potential impacts on fertility, as previously observed in the male siblings, which require careful assessment in future studies. PMID:27560547

    Full Text Available Purpose: To evaluate whether transformation of the naso-lacrimal passage as happens after dacryocystorhinostomy (DCR operation has any effect on the systemic adverse effects of topically administered timolol maleate. Materials and Methods: Fifty otherwise healthy adult patients without any prior history of cardiac or pulmonary problems scheduled for elective DCR surgery received a drop of timolol maleate 0.5% on the healthy eye. This eye served as a control. Six weeks after successful DCR surgery, the operated eye received the same medication. Parameters compared included intraocular pressure (IOP, pulse rate, blood pressure and forced expiratory volume in the first second (FEV1 findings. Observations: Post DCR patients showed an increased incidence of reduced pulse rate and FEV1. Conclusion: Timolol maleate ophthalmic preparation should be used with caution in post-DCR patients.

  17. The Adverse Events and Hemodynamic Effects of Adenosine-Based Cardiac MRI

    International Nuclear Information System (INIS)

    We wanted to prospectively assess the adverse events and hemodynamic effects associated with an intravenous adenosine infusion in patients with suspected or known coronary artery disease and who were undergoing cardiac MRI. One hundred and sixty-eight patients (64 ± 9 years) received adenosine (140 μg/kg/min) during cardiac MRI. Before and during the administration, the heart rate, systemic blood pressure, and oxygen saturation were monitored using a MRI-compatible system. We documented any signs and symptoms of potential adverse events. In total, 47 out of 168 patients (28%) experienced adverse effects, which were mostly mild or moderate. In 13 patients (8%), the adenosine infusion was discontinued due to intolerable dyspnea or chest pain. No high grade atrioventricular block, bronchospasm or other life-threatening adverse events occurred. The hemodynamic measurements showed a significant increase in the heart rate during adenosine infusion (69.3 ± 11.7 versus 82.4 ± 13.0 beats/min, respectively; p < 0.001). A significant but clinically irrelevant increase in oxygen saturation occurred during adenosine infusion (96 ± 1.9% versus 97 ± 1.3%, respectively; p < 0.001). The blood pressure did not significantly change during adenosine infusion (systolic: 142.8 ± 24.0 versus 140.9 ± 25.7 mmHg; diastolic: 80.2 ± 12.5 mmHg versus 78.9 ± 15.6, respectively). This study confirms the safety of adenosine infusion during cardiac MRI. A considerable proportion of all patients will experience minor adverse effects and some patients will not tolerate adenosine infusion. However, all adverse events can be successfully managed by a radiologist. The increased heart rate during adenosine infusion highlights the need to individually adjust the settings according to the patient, e.g., the number of slices of myocardial perfusion imaging.

    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. PMID:23307563

  1. Testing programs related to potential adverse flow effects in nuclear power plants

    International Nuclear Information System (INIS)

    Potential adverse flow effects on nuclear power plant Structures, Systems and Components (SSCs), can result from various causes. For example, reactor vessel and main steam system piping and components (including the steam dryer, safety relief and power-operated valves, and pipe supports) in BWR nuclear power plants can be damaged by pressure fluctuations and vibration resulting from acoustic resonances occurring in the main steam system or reactor vessel. The acoustic resonance phenomenon can also occur in pressurized water reactor (PWR) nuclear power plants with resulting damage to plant piping and components. Sampling probes in feedwater and condensate systems in nuclear power plants are also susceptible to adverse flow effects. The NRC staff reviews the evaluation performed by applicants for the construction and operation of nuclear power plants under 10 CFR Part 50 or Part 52 of the potential for adverse flow effects on plant SSCs. This proposed paper will discuss the various aspects of the programs established by applicants and licensees for monitoring plant data to verify that adverse flow effects are not occurring. These aspects of the test programs include the following: conducting walk-downs, and inspecting components during power ascension and operation at full licensed power conditions, dynamic response analysis of reactor internals under operational flow transients and steady-state conditions; preoperational flow-induced vibration testing of reactor internals; correlation of the test results with the analytical results.

    The purpose of this study was to examine the late adverse effects of childhood hematological disorders treated with chemotherapy and radiotherapy including whole cranial irradiation at Sapporo Medical University Hospital. Twenty-eight patients were treated with chemotherapy and 18-24 Gy of prophylactic cranial irradiation (PCI) for acute lymphoblastic leukemia (ALL), and 14 patients were treated with 3-12.8 Gy of total body irradiation (TBI) and bone marrow transplantation (BMT) for ALL, acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), myelodysplastic syndrome (MDS), malignant lymphoma, and aplastic anemia (AA). Age at diagnosis ranged from 2 to 15 years old, and 28 were males and 14 were females. All patients were disease-free more than 2 years after diagnosis. Of 42 patients, 4 patients had decreased height (less than -2 S.D.), 3 patients required hormone replacement therapy, 2 patients had mental retardation, 3 patients had leukoencephalopathy, and 1 patient had a second malignancy. Except for the cases of decreased height, 3 of 7 late adverse effects were occurred in patients who had relapse of disease, and the risk of the adverse effects seemed to be higher for those patients whose doses of PCI were 22 Gy or more, or who received an additional craniospinal irradiation due to relapse of disease, and 18 Gy of PCI did not increase the risk of adverse effects.

  6. Adverse effects in coronary angiography: a comparative study of different temperature contrast medium

    International Nuclear Information System (INIS)

    Objective: To investigate the correlation between different temperature contrast medium and the occurrence of adverse effects, including the chest discomfort, the changes of heart rate, ST segment and T wave, the operating time and the used dosage of contrast medium, in performing coronary angiography. Methods: According to the contrast medium temperature used in coronary angiography, the patients were randomly divided into two groups: room temperature group (n=521) and warm temperature group (n=522). The contrast medium used in warm temperature group was bathed in 37 ℃ water for 60 minutes when the coronary angiography was carried out. The T Wave amplitude changes ≥ 0.01 mv, ST segment depression ≥ 0.05 mv, changes in heart rate ≥ 10 times/min were brought into the positive accounting. The occurrence of adverse effects, such as palpitation, chest distress and pectoralgia, the operative time and the used dosage of contrast medium were recorded. The results were analyzed and compared between the two groups. Results: Statistically significant differences in the changes of heart rate, ST segment deviation, T wave change and operating time existed between the two groups (P<0.05). And the difference in the occurrence of adverse effects between the two groups was also statistically significant (P<0.05). Conclusion: When performing coronary angiography, warming of the contrast medium with water bath is greatly conducive to the prevention of cardiac adverse effects. (authors)

    We analyzed the cases of side effects due to antipsychotics reported to Japan's Pharmaceuticals and Medical Devices Agency (PMDA) from Jan. 2004 to Dec. 2012. We used the Japanese Adverse Drug Event Report Database (JADER) and analyzed 136 of 216,945 cases using the defined terms. We also checked the cardiac adverse effects listed in the package inserts of the antipsychotics involved. We found cases of Ikr blockade resulting in sudden death (49 cases), electrocardiogram QT prolonged (29 cases), torsade de pointes (TdP, 19 cases), ventricular fibrillation (VF, 10 cases). M2 receptor blockade was observed in tachycardia (8 cases) and sinus tachycardia (3 cases). Calmodulin blockade was involved in reported cardiomyopathy (3 cases) and myocarditis (1 case). Multiple adverse events were reported simultaneously in 14 cases. Our search of package inserts revealed warnings regarding electrocardiogram QT prolongation (24 drugs), tachycardia (23), sudden death (18), TdP (14), VF (3), myocarditis (1) and cardiomyopathy (1). We suggest that when an antipsychotic is prescribed, the patient should be monitored regularly with ECG, blood tests, and/or biochemical tests to avoid adverse cardiac effects. PMID:25069255

  11. Adverse effects of the antimalaria drug, mefloquine: due to primary liver damage with secondary thyroid involvement?

    Directory of Open Access Journals (Sweden)

    Herxheimer Andrew

    2002-03-01

    Full Text Available Abstract Background Mefloquine is a clinically important antimalaria drug, which is often not well tolerated. We critically reviewed 516 published case reports of mefloquine adverse effects, to clarify the phenomenology of the harms associated with mefloquine, and to make recommendations for safer prescribing. Presentation We postulate that many of the adverse effects of mefloquine are a post-hepatic syndrome caused by primary liver damage. In some users we believe that symptomatic thyroid disturbance occurs, either independently or as a secondary consequence of the hepatocellular injury. The mefloquine syndrome presents in a variety of ways including headache, gastrointestinal disturbances, nervousness, fatigue, disorders of sleep, mood, memory and concentration, and occasionally frank psychosis. Previous liver or thyroid disease, and concurrent insults to the liver (such as from alcohol, dehydration, an oral contraceptive pill, recreational drugs, and other liver-damaging drugs may be related to the development of severe or prolonged adverse reactions to mefloquine. Implications We believe that people with active liver or thyroid disease should not take mefloquine, whereas those with fully resolved neuropsychiatric illness may do so safely. Mefloquine users should avoid alcohol, recreational drugs, hormonal contraception and co-medications known to cause liver damage or thyroid damage. With these caveats, we believe that mefloquine may be safely prescribed in pregnancy, and also to occupational groups who carry out safety-critical tasks. Testing Mefloquine's adverse effects need to be investigated through a multicentre cohort study, with small controlled studies testing specific elements of the hypothesis.

    Background The use of food supplements containing botanicals is increasing in European markets. Although intended to maintain the health status, several cases of adverse effects to Plant Food Supplements (PFS) have been described. Objectives To describe the self-reported adverse effects collected during the European PlantLIBRA PFS Consumer Survey 2011–2012, with a critical evaluation of the plausibility of the symptomatology reported using data from the literature and from the PlantLIBRA Poisons Centers' survey. Subjects/Setting From the total sample of 2359 consumers involved in the consumers' survey, 82 subjects reported adverse effects due to a total of 87 PFS. Results Cases were self-reported, therefore causality was not classified on the basis of clinical evidence, but by using the frequency/strength of adverse effects described in scientific papers: 52 out of 87 cases were defined as possible (59.8%) and 4 as probable (4.6%). Considering the most frequently cited botanicals, eight cases were due to Valeriana officinalis (garden valerian); seven to Camellia sinensis (tea); six to Ginkgo biloba (Maidenhair tree) and Paullinia cupana (guarana). Most adverse events related to the gastrointestinal tract, nervous and cardiovascular systems. Conclusions Comparing the data from this study with those published in scientific papers and obtained by the PlantLIBRA Poisons Centers' survey, some important conclusions can be drawn: severe adverse effects to PFS are quite rare, although mild or moderate adverse symptoms can be present. Data reported in this paper can help health professionals (and in particular family doctors) to become aware of possible new problems associated with the increasing use of food supplements containing botanicals.

    Full Text Available As a further step towards the modernization of acupuncture, the objective of this review was to figure out the frequency and severity of adverse complications and events in acupuncture treatment reported from 1980 to 2013 in China. All first-hand case reports of acupuncture-related complications and adverse events that could be identified in the scientific literature were reviewed and classified according to the type of complication and adverse event, circumstance of the event, and long-term patient outcome. The selected case reports were published between 1980 and 2013 in 3 databases. Relevant papers were collected and analyzed by 2 reviewers. Over the 33 years, 182 incidents were identified in 133 relevant papers. Internal organ, tissue, or nerve injury is the main complications of acupuncture especially for pneumothorax and central nervous system injury. Adverse effects also included syncope, infections, hemorrhage, allergy, burn, aphonia, hysteria, cough, thirst, fever, somnolence, and broken needles. Qualifying training of acupuncturists should be systemized and the clinical acupuncture operations should be standardized in order to effectively prevent the occurrence of acupuncture accidents, enhance the influence of acupuncture, and further popularize acupuncture to the rest of the world.

    2007-11-01

    Because of their small size and ongoing organ development, children may be more susceptible than adults to the harmful effects of toxic chemicals. The objective of the study reported here was to identify frequent locations, released substances, and factors contributing to short-term chemical exposures associated with adverse health consequences experienced by children. The study examined the Hazardous Substances Emergency Events Surveillance (HSEES) system data from 1996-2003. Eligible events involved the acute release of a hazardous substance associated with at least one child being injured. The study found that injured children were predominantly at school, home, or a recreational center when events took place. School-related events were associated with the accidental release of acids and the release of pepper spray by pranksters. Carbon monoxide poisonings occurring in the home, retail stores, entertainment facilities, and hotels were responsible for about 10 percent of events involving child victims. Chlorine was one of the top chemicals harmful to children, particularly at public swimming pools. Although human error contributed to the majority of releases involving child victims, equipment failure was responsible for most chlorine and ammonia releases. The authors conclude that chemical releases resulting in injury to children occur mostly in schools, homes, and recreational areas. Surveillance of acute hazardous chemical releases helped identify contributing causes and can guide the development of prevention outreach activities. Chemical accidents cannot be entirely prevented, but efforts can be taken to provide safer environments in which children can live, learn, and play. Wide dissemination of safety recommendations and education programs is required to protect children from needless environmental dangers. PMID:18044249

    2010-10-01

    Full Text Available Abstract Background Multi-item adverse drug event (ADE associations are associations relating multiple drugs to possibly multiple adverse events. The current standard in pharmacovigilance is bivariate association analysis, where each single drug-adverse effect combination is studied separately. The importance and difficulty in the detection of multi-item ADE associations was noted in several prominent pharmacovigilance studies. In this paper we examine the application of a well established data mining method known as association rule mining, which we tailored to the above problem, and demonstrate its value. The method was applied to the FDAs spontaneous adverse event reporting system (AERS with minimal restrictions and expectations on its output, an experiment that has not been previously done on the scale and generality proposed in this work. Results Based on a set of 162,744 reports of suspected ADEs reported to AERS and published in the year 2008, our method identified 1167 multi-item ADE associations. A taxonomy that characterizes the associations was developed based on a representative sample. A significant number (67% of the total of potential multi-item ADE associations identified were characterized and clinically validated by a domain expert as previously recognized ADE associations. Several potentially novel ADEs were also identified. A smaller proportion (4% of associations were characterized and validated as known drug-drug interactions. Conclusions Our findings demonstrate that multi-item ADEs are present and can be extracted from the FDA’s adverse effect reporting system using our methodology, suggesting that our method is a valid approach for the initial identification of multi-item ADEs. The study also revealed several limitations and challenges that can be attributed to both the method and quality of data.

  20. The role of ADHD in academic adversity: disentangling ADHD effects from other personal and contextual factors.

    Students with attention-deficit/hyperactivity disorder (ADHD) experience significant academic difficulties that can lead to numerous negative academic consequences. With a focus on adverse academic outcomes, this study seeks to disentangle variance attributable to ADHD from variance attributable to salient personal and contextual covariates. Responses from 136 students with ADHD and 3,779 non-ADHD peers from 9 high schools were analyzed using logistic regression. Dependent measures included academic failure, grade repetition, school refusal, changing classes and school, school exclusion, and schoolwork noncompletion. Covariates comprised personal (e.g., sociodemographics, personality, prior achievement, specific learning disabilities, motivation) and contextual (e.g., school size, school socioeconomic status, school average achievement) factors. Findings indicated that, after accounting for personal and contextual covariates, ADHD explained significant variance in numerous adversities (schoolwork noncompletion, school suspension, school expulsion, changing schools, grade repetition). Thus, beyond the effects of numerous personal and contextual covariates, ADHD has a distinct presence in students' academic adversity. Also interesting, after accounting for other personal and contextual factors, was academic adversity with which ADHD was not associated. Findings provide direction for educational intervention targeting ADHD and associated factors found to be significant in the study. PMID:24820011

    Nutritional supplementation during pregnancy is increasingly recommended especially in low-resource settings, but its oral health impacts have not been studied. Our aim was to examine whether supplementation with multiple micronutrients (MMN) or small-quantity lipid-based nutrient supplements affects dental caries development or periodontal health in a rural Malawian population. The study was embedded in a controlled iLiNS-DYAD trial that enrolled 1391 pregnant women nutritional and health status. At the end of the intervention, the prevalence of caries was 56.7%, 69.1% and 63.3% (P = 0.004), and periodontitis 34.9%, 29.8% and 31.2% (P = 0.338) in the IFA, MMN and LNS groups, respectively. Compared with the IFA group, women in the MMN group had 0.60 (0.18-1.02) and in the LNS group 0.59 (0.17-1.01) higher mean number of caries lesions. In the absence of baseline oral health data, firm conclusions on causality cannot be drawn. However, although not confirmatory, the findings are consistent with a possibility that provision of MMN or LNS may have increased the caries incidence in this target population. Because of the potential public health impacts, further research on the association between gestational nutrient interventions and oral health in low-income settings is needed. PMID:26194850

    Medications are being used with greater frequency to address pediatric mental health problems, and in recent years atypical antipsychotic (AAP) prescriptions have increased more than any other class. Acute care practitioners must be aware of the pharmacology of AAPs and the conditions, on- and off-label, for which they are prescribed. This involves identifying and managing side effects that manifest both mentally and physically. Although “atypicality” confers a lower risk of movement side effects compared to conventional agents, children are more sensitive than adults to extrapyramidal reactions. Like adults, they also may present with toxic sedation, confusion, cardiovascular dysfunction, and metabolic derangements. Evaluation and management of these toxicities requires an index of suspicion, a careful symptom and medication history, physical examination, and targeted interventions. This review is designed to orient the emergency practitioner to the challenging task of recognizing and treating adverse effects related to acute and chronic atypical antipsychotic exposure in children.

    Full Text Available The mammalian target of rapamycin inhibitors (mTOR-I, sirolimus and everolimus, are immunosuppressive drugs largely used in renal transplantation. The main mechanism of action of these drugs is the inhibition of the mammalian target of rapamycin (mTOR, a regulatory protein kinase involved in lymphocyte proliferation. Additionally, the inhibition of the crosstalk among mTORC1, mTORC2, and PI3K confers the antineoplastic activities of these drugs. Because of their specific pharmacological characteristics and their relative lack of nephrotoxicity, these inhibitors are valid option to calcineurine inhibitors (CNIs for maintenance immunosuppression in renal transplant recipients with chronic allograft nephropathy. However, as other immunosuppressive drugs, mTOR-I may induce the development of several adverse effects that need to be early recognized and treated to avoid severe illness in renal transplant patients. In particular, mTOR-I may induce systemic nonnephrological side effects including pulmonary toxicity, hematological disorders, dysmetabolism, lymphedema, stomatitis, cutaneous adverse effects, and fertility/gonadic toxicity. Although most of the adverse effects are dose related, it is extremely important for clinicians to early recognize them in order to reduce dosage or discontinue mTOR-I treatment avoiding the onset and development of severe clinical complications.

    Opioid effects are potentiated by cannabinoid agonists including anandamide, an endocannabinoid. Inter-individual variability in responses to opioids is a major clinical problem. Multiple deaths and anoxic brain injuries occur every year because of opioid-induced respiratory depression (RD) in surgical patients and drug abusers of opioids and cannabinoids. This study aimed to determine specific associations between genetic variants of fatty acid amide hydrolase (FAAH) and postoperative central opioid adverse effects in children undergoing tonsillectomy. This is a prospective genotype-blinded observational study in which 259 healthy children between 6 and 15 years of age who received standard perioperative care with a standard anesthetic and an intraoperative dose of morphine were enrolled. Associations between frequent polymorphisms of FAAH and central postoperative opioid adverse effects including, RD, postoperative nausea and vomiting (PONV) and prolonged stay in Post Anesthesia Recovery Room (postoperative anesthesia care unit, PACU) due to RD and PONV were analyzed. Five specific FAAH single nucleotide polymorphisms (SNPs) had significant associations with more than twofold increased risk for refractory PONV (adjusted PPACU stay in white children undergoing tonsillectomy. The FAAH SNP, rs324420, is a missense mutation with altered FAAH function and it is linked with other FAAH SNPs associated with PONV and RD in our cohort; association between PONV and rs324420 was confirmed in our extended cohort with additional 66 white children. Specific FAAH polymorphisms are associated with refractory PONV, opioid-related RD, and prolonged PACU stay due to opioid adverse effects in white children undergoing tonsillectomy. PMID:25558980

    Full Text Available Pharmaceutical care (PC has been shown to improve the outcome of drug therapy in many disease conditions. HIV/AIDS is one of the disease conditions that are fraught with many problems that can benefit from this new emphasis of pharmacy practice also known as ‘pharmacists care’. Adverse drug reactions or effects are unintended and undesirable effects of drugs other than their known and expected actions which can be unpleasant and sometimes fatal. This study is designed to evaluate the impact of pharmaceutical care activities on the occurrence of side/adverse drug reactions in HIV/AIDS patients receiving antiretroviral drugs. The components of the American society of health-system pharmacists (ASHP guidelines on ‘standardized method for pharmaceutical care’ was used as a data collection instrument to evaluate, document and intervene in the antiretroviral therapy of about one thousand four hundred and seventy three (1,473 patients. The study identified about sixty (60 different types of side/adverse effects occurring among these patients through observation and patient complaints. The study also showed significant reduction in the incidence of side/adverse drug effects following the Pharmacist’s intervention activities, p ≥ 0.5. The study showed that pharmacists’ interventions in antiretroviral drug therapy through Pharmaceutical care can significantly reduce the incidence of side/adverse drug effects in HIV/AIDS patients receiving antiretroviral drugs.

  6. Development of STI/AOT optimization methodology and an application to the AFWPs with adverse effects

    International Nuclear Information System (INIS)

    Adverse effects caused by the surveillance test for the components of nuclear power plant involve plant transients, unnecessary wear, burden on licensee's time, and the radiation exposure to personnel along with the characteristics of each component. The optimization methodology of STI and AOT has been developed and applied to AFWPs of a reference plant. The approach proposed in this paper consists of the results in minimal mean unavailability of the two-out-of-four system with adverse effects are analytically calculated for the example system. The surveillance testing strategy are given by the sequential test, the staggered test and the train staggered test, which is a mixed test scheme. In the system level, the sensitivity analyses for the STI and AOT, are performed for the measure of the system unavailability of the top event in the fault tree developed for the example system. This methodology may contribute to establishing the basis for the risk-based regulations. (author)

    Many adverse drug effects (ADEs) can be attributed to drug interactions. Spontaneous reporting systems (SRS) provide a rich opportunity to detect novel post-marketed drug interaction adverse effects (DIAEs), as they include populations not well represented in clinical trials. However, their identification in SRS is nontrivial. Most existing research have addressed the statistical issues used to test or verify DIAEs, but not their identification as part of a systematic large scale database-wide mining process as discussed in this work. This paper examines the application of a highly optimized and tailored implementation of the Apriori algorithm, as well as methods addressing data quality issues, to the identification of DIAEs in FDAs SRS.

    2008-12-01

    Active cigarette smoking causes a broad spectrum of diseases that extend to many different organ systems. Its numerous deleterious health effects, combined with the substantial prevalence of cigarette smoking, make it a major worldwide cause of death. Smoking contributes so heavily to the mortality burden because it is a major cause of vascular disease, cancer and chronic obstructive pulmonary disease. In addition to these diseases, cigarette smoking also causes other respiratory symptoms, adversely affects reproductive outcomes and is a cause of diminished health status. Furthermore, exposure to secondhand smoke is an established cause of coronary heart disease and lung cancer, as well as a host of other adverse health effects. Given that cigarette smoking is such a major threat to global public health, controlling the worldwide epidemic of cigarette smoking would lead to enormous public health benefits. Strategies to control cigarette smoking at the societal level include smoke-free workplace legislation, increasing cigarette taxes and regulating cigarette advertising. On the individual level, preventing the initiation of cigarette smoking among youths is the optimal strategy; in practice, discovering efficacious primary prevention interventions has proven challenging. During the past two decades, major advances have been made in extending the menu of options available to assist dependent smokers in successfully quitting smoking. Successfully combating cigarette smoking requires a broad-based commitment to smoking control from multiple stakeholders, along with a multifaceted strategy that addresses both societal and individual factors.

    Unintended pregnancy is among the most troubling public health problems and a major reproductive health issue worldwide imposing appreciable socioeconomic burden on individuals and society. Governments generally plan to control growth of births (especially wanted births as well as orphans and illegitimate births) imposing extra burden on public funding of the governments which inevitably affects economic efficiency and leads to economic slowdown, too. The present narrative review focuses on socioeconomic impacts of unintended pregnancy from the health system perspective. Follow of Computerized searches of Academic, 53 scientific journals were found in various databases including PubMed, EMBASE, ISI, Iranian databases, IPPE, UNFPA (1985-2013). Original articles, review articles, published books about the purpose of the paper were used. During this search, 20 studies were found which met the inclusion criteria. Unintended pregnancy is one of the most critical challenges facing the public health system that imposes substantial financial and social costs on society. On the other hand, affecting fertility indicators, it causes reduced quality of life and workforce efficiency. Therefore lowering the incidence of intended pregnancies correlates with elevating economic growth, socio-economic development and promoting public health. Regarding recent policy changes in Iran on family planning programs and adopting a new approach in increasing population may place the country at a higher risk of increasing the rate of unintended pregnancy. Hence, all governmental plans and initiatives of public policy must be regulated intelligently and logically aiming to make saving in public spending and reduce healthcare cost inflation.

    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.

  15. Predicting Nonauditory Adverse Radiation Effects Following Radiosurgery for Vestibular Schwannoma: A Volume and Dosimetric Analysis

    International Nuclear Information System (INIS)

    Purpose: To define clinical and dosimetric predictors of nonauditory adverse radiation effects after radiosurgery for vestibular schwannoma treated with a 12 Gy prescription dose. Methods: We retrospectively reviewed our experience of vestibular schwannoma patients treated between September 2005 and December 2009. Two hundred patients were treated at a 12 Gy prescription dose; 80 had complete clinical and radiological follow-up for at least 24 months (median, 28.5 months). All treatment plans were reviewed for target volume and dosimetry characteristics; gradient index; homogeneity index, defined as the maximum dose in the treatment volume divided by the prescription dose; conformity index; brainstem; and trigeminal nerve dose. All adverse radiation effects (ARE) were recorded. Because the intent of our study was to focus on the nonauditory adverse effects, hearing outcome was not evaluated in this study. Results: Twenty-seven (33.8%) patients developed ARE, 5 (6%) developed hydrocephalus, 10 (12.5%) reported new ataxia, 17 (21%) developed trigeminal dysfunction, 3 (3.75%) had facial weakness, and 1 patient developed hemifacial spasm. The development of edema within the pons was significantly associated with ARE (p = 0.001). On multivariate analysis, only target volume is a significant predictor of ARE (p = 0.001). There is a target volume threshold of 5 cm3, above which ARE are more likely. The treatment plan dosimetric characteristics are not associated with ARE, although the maximum dose to the 5th nerve is a significant predictor of trigeminal dysfunction, with a threshold of 9 Gy. The overall 2-year tumor control rate was 96%. Conclusions: Target volume is the most important predictor of adverse radiation effects, and we identified the significant treatment volume threshold to be 5 cm3. We also established through our series that the maximum tolerable dose to the 5th nerve is 9 Gy.

    There are many misconceptions of the effects on health from the accident at Chernobyl. The 1996 conference in Vienna held one decade after the event, and more recent material being examined by UNSCEAR, provide a more soundly-based view. Apart from an increase in thyroid cancer in some of those people exposed as children, there is no evidence of a major public health impact to date from radiation exposures caused by the accident. There is no increase in leukemia attributable to radiation exposure, the most likely indicator, even in the group of radiation workers. Definitive studies of the health status of the various groups involved have been difficult to carry out because of the socio-economic conditions. Clearly, their continuation is going to need further international cooperation. (author)

    Full Text Available This study aimed at evaluating the incidence of adverse effects leading to treatment discontinuation of antihypertensive drugs within the same therapeutic class. Individual medical records were searched to identify those hypertensive patients who had been commenced on antihypertensive therapy during a 24-month period and who had subsequently for a reason(s discontinued the therapy. The results showed variation in discontinuation rates for drugs within same class, and that might be related to the relative frequency of specific adverse effects. Cough was the reason cited for discontinuation of angiotensin converting enzyme inhibitors, with linosopril appearing to be better tolerated than captopril (39% vs 48% ; peripheral oedema with calcium channel blockers, with amlodipine appearing to be better tolerated than nifedipine (29% vs 38% and bradycardia with beta adrenergic receptor blockers, with propranolol better tolerated than atenolol (0% vs 48%. Diuretics showed the lowest discontinuation rate (3.3% mainly due to hypokalemia, with thiazide better tolerated than frusemide (11% vs 43%. Prescribers should verify their use of antihypertensive drugs to ensure that they prescribe drugs with lower adverse effect rates, in order that patients with hypertension continue using the medication in the long term, thereby reducing the risk of developing cardiovascular complications associated with uncontrolled blood pressure.

    Nepal is a country economically dependent on climate-sensitive industries. It is highly vulnerable to the environmental, social, economic and health impacts of climate change. The objective of this study is to explore community perceptions of climate variability and human health risks. In this letter, we present a cross sectional study conducted between August 2013 and July 2014 in the Tanahu district of Nepal. Our analysis is based on 258 face-to-face interviews with household heads utilizing structured questionnaires. Over half of the respondents (54.7%) had perceived a change in climate, 53.9% had perceived an increase in temperature in the summer and 49.2% had perceived an increase in rainfall during the rainy season. Half of the respondents perceived an increase in the number of diseases during the summer, 46.5% perceived an increase during the rainy season and 48.8% during winter. Only 8.9% of the respondents felt that the government was doing enough to prevent climate change and its impact on their community. Belonging to the Janajati (indigenous) ethnic group, living in a pakki, super-pakki house and belonging to poor or mid-level income were related to higher odds of perceiving climate variability. Illiterates were less likely to perceive climate variability. Respondents living in a pakki house, super-pakki, or those who were poor were more likely to perceive health risks. Illiterates were less likely to perceive health risks.

    Full Text Available Objective: To provide a frame to estimate the systemic impact (side/adverse events of (novel therapeutic targets by taking into consideration drugs potential on the numerous districts involved in rheumatoid arthritis (RA from the inflammatory and immune response to the gut-intestinal (GI microbiome.Methods: We curated the collection of molecules from high-throughput screens of diverse (multi-omic biochemical origin, experimentally associated to RA. Starting from such collection we generated RA-related protein-protein interaction (PPI networks (interactomes based on experimental PPI data. Pharmacological treatment simulation, topological and functional analyses were further run to gain insight into the proteins most affected by therapy and by multi-omic modelling.Results: Simulation on the administration of MTX results in the activation of expected (apoptosis and adverse (nitrogenous metabolism alteration effects. Growth factor receptor-bound protein 2 (GRB2 and Interleukin-1 Receptor Associated Kinase-4 (IRAK4, already an RA target emerge as relevant nodes. The former controls the activation of inflammatory, proliferative and degenerative pathways in host and pathogens. The latter controls immune alterations and blocks innate response to pathogens.Conclusions: This multi-omic map properly recollects in a single analytical picture known, yet complex, information like the adverse/side effects of MTX, and provides a reliable platform for in silico hypothesis testing or recommendation on novel therapies. These results can support the development of RA translational research in the design of validation experiments and clinical trials, as such we identify GRB2 as a robust potential new target for RA for its ability to control both synovial degeneracy and dysbiosis, and, conversely, warn on the usage of IRAK4-inhibitors recently promoted, as this involves potential adverse effects in the form of impaired innate response to pathogens.

    In Latin America, little research has been conducted regarding exposure to adverse childhood experiences (ACEs), mental health, and health-related quality of life (HRQoL) among foster children. This study examined the association between ACEs and mental health, posttraumatic stress disorder (PTSD), and HRQoL in Chilean foster girls relative to age-matched Chilean family girls. Data were obtained from 27 Chilean foster girls and 27 Chilean girls ages 6 to 17 years living in family homes. Standardized self- and proxy-report measures were used. Foster girls reported more ACEs than controls in terms of familial and nonfamilial sexual abuse and both emotional and physical neglect. Girls living in foster care had a significantly higher rate of PTSD, displayed greater behavioral and emotional problems, and reported a lower HRQoL. Analysis confirmed the well-known cumulative risk hypothesis by demonstrating a significant positive association between the number of ACEs and PTSD symptom severity and a significant negative association with HRQoL. Chilean foster girls endured more ACEs that impair mental health and HRQoL than age-matched peers living with their families. These findings have implications for out-of-home care services in Latin America, highlighting the need to implement not only appropriate trauma-focused treatments but also appropriate prevention strategies.

    To determine the correlation between the working environment and the health status of employees in solar greenhouse, 1171 employees were surveyed. The results show the 'Greenhouse diseases' are affected by many factors. Among general uncomforts, the morbidity of the bone and joint damage is the highest and closely related to labor time and age. Planting summer squash and wax gourd more easily cause skin pruritus. Asthma-related cough, eye disease, and skin pruritus are significantly correlated with the cultivation of wax gourd. The application of inorganic fertilizer and fertigation dramatically induce the bone and joint damage. The smell of covering film greatly influence skin pruritus. Personal protection is badly scanty and normative occupational health and safety need to be completed. PMID:25716566

    Sleep loss, circadian desynchronization, and work overload occur to some extent for ground and flight crews, prior to and during spaceflight missions. Ground evidence indicates that such risk factors may lead to performance decrements and adverse health outcomes, which could potentially compromise mission objectives. Efforts are needed to identify the environmental and mission conditions that interfere with sleep and circadian alignment, as well as individual differences in vulnerability and resiliency to sleep loss and circadian desynchronization. Specifically, this report highlights a collection of new evidence to better characterize the risk and reveals new gaps in this risk as follows: Sleep loss is apparent during spaceflight. Astronauts consistently average less sleep during spaceflight relative to on the ground. The causes of this sleep loss remain unknown, however ground-based evidence suggests that the sleep duration of astronauts is likely to lead to performance impairment and short and long-term health consequences. Further research is needed in this area in order to develop screening tools to assess individual astronaut sleep need in order to quantify the magnitude of sleep loss during spaceflight; current and planned efforts in BHP's research portfolio address this need. In addition, it is still unclear whether the conditions of spaceflight environment lead to sleep loss or whether other factors, such as work overload lead to the reduced sleep duration. Future data mining efforts and continued data collection on the ISS will help to further characterize factors contributing to sleep loss. Sleep inertia has not been evaluated during spaceflight. Ground-based studies confirm that it takes two to four hours to achieve optimal performance after waking from a sleep episode. Sleep inertia has been associated with increased accidents and reduced performance in operational environments. Sleep inertia poses considerable risk during spaceflight when emergency

    2013-04-01

    Full Text Available Background: Proton pump inhibitors (PPIs have provided important benefits in the management of gastroesophageal reflux disease (GERD, peptic ulcer disease and in the prevention of non steroidal antiinflammatory drugs and aspirin-related ulcer complications. PPIs are also the most commonly used medications for stress ulcer prophylaxis, despite little evidence to support their use in non-intensive care unit. Discussion: Considering the widespread use of PPIs, these agents’ overall safety profile is unquestionable. However, there is growing evidence that PPIs use may be associated with an increased risk of enteric infections, pneumonia, hip fractures, vitamin B12 deficiency. Overall, until now, none of these adverse effects have discouraged the PPIs treatment. Recently attention has been placed on a more important potential adverse effect of PPIs, their interaction with clopidogrel to which they are associated for the prophylaxis of gastrointestinal bleeding. Preliminary results of laboratory tests suggest that omeprazole reduces clopidogrel’s antiplatelet effect. The interaction seems to involve the competitive inhibition of the CYP2C19 isoenzyme. The effect appears to be clinically important, as some retrospective studies have shown an increase in adverse cardiovascular outcomes when PPIs and clopidogrel are used concomitantly. Some studies indicate that pantoprazole and esomeprazole are not associated with impaired response to clopidogrel. However, the available data for PPIs other than omeprazole do not allow definitive conclusions to be drawn about whether is a class effect. Conclusions: Specifically designed and randomized clinical studies are needed to define the interaction between PPIs and clopidogrel. Moreover, alternative treatment strategies with histamine- 2 receptor antagonists that are not dependent on cytochrome p450 2C19 should be tested in future studies.

    Exposure to stress during critical periods of development can have adverse effects on adult health behaviors, and genetic vulnerabilities may enhance these stress effects. We carried out an exploratory examination of psychological, physiological, and behavioral characteristics of 252 healthy young adults for the impact of early-life adversity (ELA) in relation to the G-to-A single nucleotide polymorphism (SNP), rs9296158, of the FKBP5 gene. FKBP5 is a molecular cochaperone that contributes to the functional status of the glucocorticoid receptor (GR) and to the quality of corticosteroid signaling. FKBP5 expression is upregulated by cortisol exposure during stressful episodes, with greater upregulation seen in A-allele carriers. As such, FKBP5 expression and GR function may be environmentally sensitive in A-allele carriers and therefore suitable for the study of gene-by-environment (G × E) interactions. Compared with FKBP5, GG homozygotes (N=118), A-allele carriers (N = 132) without psychiatric morbidity had progressively worse performance on the Stroop color-word task with increasing levels of ELA exposure (Genotype × ELA, F=5.14, P=0.007), indicating a G × E interaction on working memory in early adulthood. In addition, heart rate response to mental stress was diminished overall in AA/AG-allele carriers (F=5.15, P=0.024). Diminished working memory and attenuated autonomic responses to stress are both associated with risk for alcoholism and other substance use disorders. The present data suggest that FKBP5 in the GR pathway may be a point of vulnerability to ELA, as seen in this group of non-traumatized young adults. FKBP5 is accordingly a potential target for more extensive studies of the impact of ELA on health and health behaviors in adulthood. PMID:26632991

    Full Text Available Introduction Recent evidence indicates that chronic diseases and mental illness are associated. In the Middle Eastern country of Jordan, chronic diseases and frequent mental distress (FMD are increasing; however, the capacity for mental health care is limited. The objective of this study was to determine the association between FMD, chronic conditions, and adverse health behaviors in Jordan. Methods The third cycle of the Jordan Behavioral Risk Factor Surveillance Survey (2007 served as the data source for this study. The sample consisted of 3,612 noninstitutionalized Jordanian adults aged 18 years or older. Logistic regression was used to obtain odds ratios for the association between chronic conditions, health behaviors, and FMD adjusted for age, sex, marital status, education, income, and employment. Results In the adjusted models, people with hypertension (adjusted odds ratio [AOR], 2.0; 95% confidence interval [CI], 1.6–2.7, high cholesterol (AOR, 2.3; 95% CI, 1.6–3.2, diabetes (AOR, 1.6; 95% CI, 1.1–2.4, and asthma (AOR, 2.2; 95% CI, 1.5–3.1 and smokers (AOR, 1.5; 95% CI, 1.1–2.0 were more likely to have FMD than people without each of these conditions. Adults who reported vigorous physical activity were less likely to have FMD (AOR, 0.6; 95% CI, 0.4–0.9 than their less active counterparts. Conclusions In Jordan, FMD was associated with several chronic conditions. As a result, we suggest additional research to examine the complex relationship between FMD and chronic conditions. More doctors in the primary health care system should be trained in mental health.

    War and other forms of armed conflict have profound adverse effects on population health. It is important to document these effects to inform the general public and policy makers about the consequences of armed conflict, provide services to meet the needs of affected populations, protect human rights and document violations of international humanitarian law, and help to prevent future armed conflict. Documentation can be accomplished with surveillance, epidemiological surveys, and rapid assessment. Challenges include inadequate or absent data systems, social breakdown, forced migration, reporting biases, and the fog of war. The adverse effects of the Iraq War on population health demonstrate how the effects of armed conflict on population health can be documented. We recommend the establishment of an independent mechanism, operated by the United Nations or a multilateral organization, to investigate and document the effects of armed conflict on population health.

    Energy drink sales are expected to reach $52 billion by 2016. These products, often sold as dietary supplements, typically contain stimulants. The Dietary Supplement Protection Act claims an exemplary public health safety record. However, in 2011 the number of emergency department visits related to consumption of energy drinks exceeded 20,000. Nearly half of these visits involved adverse effects occurring from product misuse. Political, social, economic, practical, and legal factors shape the landscape surrounding this issue. In this policy analysis, we examine 3 options: capping energy drink caffeine levels, creating a public education campaign, and increasing regulatory scrutiny regarding the manufacture and labeling of energy drinks. Increased regulatory scrutiny may be in order, especially in light of wrongful death lawsuits related to caffeine toxicity resulting from energy drink consumption. PMID:24832439

    Full Text Available Stephanie Andrews,1 Rita Holden21H Lee Moffitt Cancer Center and Research Institute, Tampa, FL, 2St Luke's Hospital and Health Network Cancer Center, Easton, PA, USAAbstract: When diagnosed in its early stages, melanoma is highly treatable and associated with good long-term outcomes; however, the prognosis is much poorer for patients diagnosed with advanced or metastatic melanoma. For decades, available treatments were effective in only a few patients and associated with significant safety concerns. Ipilimumab is a novel immunotherapy which has proved to be an exciting breakthrough in the treatment of melanoma. It is the first drug approved for the treatment of melanoma by the Food and Drug Administration (FDA which has shown a survival benefit in a randomized Phase III clinical trial. The objective of this review is to provide information on the administration, treatment responses, and expected outcomes of treatment of metastatic melanoma with the new immunotherapeutic agent, ipilimumab, a drug with a unique mechanism of action that differentiates it from current treatments. Guidelines for the management of immune-related adverse events associated with ipilimumab therapy are also presented. These stress vigilance, prompt intervention, and the use of corticosteroids as appropriate. Various ipilimumab-associated immune-related adverse events, both common (enterocolitis, dermatitis and less frequent (hepatitis, hypophysitis, are illustrated in case studies. Nurses are uniquely positioned to provide patient and caregiver education on how this new therapy differs from traditional cytotoxic agents, to recognize the signs and symptoms of immune-related adverse events, and to report them immediately, and finally, to be aware of the patterns of response that are commonly observed in patients receiving ipilimumab therapy.Keywords: melanoma, ipilimumab, immunotherapy, case studies

    The elderly are more susceptible to adverse drugs effects due to a variety of factors, such as excessive and concomitant use of several drugs, administration errors, physiological changes in the body that alter the pharmacodynamics and pharmacokinetics. In order to determine the main therapeutic classes involved in hospital admissions of elderly people due to intoxication and adverse drug effects, as well as major health problems related to these events, 9,793 hospitalizations of people aged 60 or over registered in the Hospital Information System of the Unified Health System (SIH-SUS) in the period of 2004 to 2008 were analyzed. Unspecified drugs, systemic antibiotics, psychotropics, psychoactives, antiepileptics, sedatives, hypnotics and antiparkinsonians accounted for 57% of the total of admissions analyzed. Injuries and falls were the main health problems related to intoxication and adverse drug effects. Hospitalizations due to injuries were associated with analgesic, antipyretic and antirheumatic non-opioid. Falls were associated with systemic antibiotics, contradicting studies which point out psychotropic drugs as the main drug involved in these events. The results reflect the growing trend of problems associated with drug use by elderly people. It was verified that the consumption profile alone is not sufficient to explain the concentration of cases of the major therapeutic classes. We suggest the adoption of more effective programs of pharmacovigilance, capable of intervening at different stages of drug use: prescribing, dispensing, marketing, administration and compliance.

    The small Pacific Island nation of Palau has alarmingly high rates of betel nut with tobacco use and obesity among the entire population including pregnant women. This study aimed to determine the effects of betel nut with tobacco use and pre-pregnancy obesity on adverse birth outcomes. This study used retrospective cohort data on 1171 Palauan women who gave birth in Belau National Hospital in Meyuns, Republic of Palau between 2007 and 2013. The exposures of interest were pre-pregnancy obesity and reported betel nut with tobacco use during pregnancy. The primary outcomes measured were preterm birth and low birth weight among full-term infants. A significantly increased risk for low birth weight among full-term infants was demonstrated among those women who chewed betel nut with tobacco during pregnancy when other known risk factors were controlled for. Additionally, pre-pregnancy obesity was associated with a significantly increased risk for preterm birth when other known risk factors were controlled for. Both betel nut with tobacco use and pre-pregnancy obesity were associated with higher risks for adverse birth outcomes. These findings should be used to drive public health efforts in Palau, as well as in other Pacific Island nations where these studies are currently lacking. PMID:26994610

Explains the molecular, cytologic and histopathologic events that lead to altered physiologic and metabolic functions and their clinical manifestations. Includes chapters on legal issues, economic aspects, nursing, psychological issues and quality of life. The literature on the late effects of cancer treatment is widely scattered in different journals since all major organ systems are affected and management is based on a variety of medical and surgical treatments. The aim of ALERT - Adverse Late Effects of Cancer Treatment is to offer a coherent multidisciplinary approach to the care of cancer survivors. The central paradigm is that cytotoxic multimodal therapy results in a perpetual cascade of events that affects each major organ system differently and is expressed continually over time. Essentially, radiation and chemotherapy are intense biologic modifiers that allow for cancer cure and cancer survivorship but accelerate senescence of normal tissues and increase the incidence of age-related diseases and second malignant tumors. Volume 1 of this two-volume work focuses on the general concepts and principles relevant to late effects and on the dynamic interplay of molecular, cytologic and histopathologic events that lead to altered physiologic and metabolic functions and their clinical manifestations.

    Prenatal exposure to environmental chemicals or drugs has been associated with functional or structural deficits and the development of diseases in later life. For example, developmental neurotoxicity (DNT) is triggered by lead, and this compound may predispose to neurodegenerative diseases in later life. The molecular memory for such late consequences of early exposure is not known, but epigenetic mechanisms (modification of the chromatin structure) could take this role. Examples and underlying mechanisms have been compiled here for the field of DNT. Moreover, we addressed the question as to what readout is suitable for addressing drug memory effects. We summarize how complex developmental processes can be modelled in vitro by using the differentiation of human stem cells. Although cellular models can never replicate the final human DNT phenotype, they can model the adverse effect that a chemical has on key biological processes essential for organ formation and function. Highly information-rich transcriptomics data may inform on these changes and form the bridge from in vitro models to human prediction. We compiled data showing that transcriptome analysis can indicate toxicity patterns of drugs. A crucial question to be answered in our systems is when and how transcriptome changes indicate adversity (as opposed to transient adaptive responses), and how drug-induced changes are perpetuated over time even after washout of the drug. We present evidence for the hypothesis that changes in the histone methylation pattern could represent the persistence detector of an early insult that is transformed to an adverse effect at later time-points in life.

    Full Text Available Ischemia and hemorrhage are the conditions which may lead to stroke. As stroke is a medical emergency, treated with medications such as aspirin, clopidogrel and dipyridamole. In the present study the combination and individual adverse effects of aspirin and clopidogrel medication were studied. The study during was around nine months in one of the private hospital at Hyderabad, Andhra Pradesh, India. Adverse effects evaluation was based on WHO guide lines and Naranjo’s Algorithm. Total 69 stroke patients were taken in to studies. 46 (66.66% were males and 23 (33.33% were females. The number of ischemic stroke patients was 39(56.5% and hemorrhage stroke was 30(43.4%. Among 41 patients, 19 patients was on Aspirin (46.34%, 10 patients was on clopidogral (24.34% and 12 patients was on combinations medication (29.26%. Adverse effects reported among the antiplatelate users were 6 patients. Among these 6 patients 4 patients were observed with upper gastrointestinal bleeding (UGI the overall percentage was 66.66% and 2 patients were observed with Vomiting, the overall percentage was 33.33%. In this study, the relative risk reduction for secondary stroke prevention was 37% with use of a combination of extended- release dipyridamole and aspirin. Importantly, the risk of major bleeding attributable to the combination therapy was no greater than that seen with aspirin alone. The benefit of clopidogrel over aspirin for the prevention of vascular events was a relative risk reduction of 8.7%.In addition, there was less major bleeding in the clopidogrel group, yielding a relative net benefit of about 10%. This study revels clopidogrel is the safe drug when compared with Aspirin and as well as combination therapy.

    The effects of high, medium and low levels of perinatal complications and family adversity on intelligence quotient (IQ) scores were examined in a large sample of Dunedin children tested every second year in the age group 3-13 years. The aim was to test the hypothesis that favourable environmental circumstances attenuate the effects of perinatal complications on later cognitive ability. The results did not support this hypothesis but rather suggested that perinatal complications and family adversity have independent adverse effects on the development of children's cognitive ability.

    The taxane chemotherapeutic agent docetaxel has been utilized in the management of breast cancer in the adjuvant, neoadjuvant and metastatic setting. Although well tolerated by the majority of patients, docetaxel toxicity may limit the dose which can be administered. Adverse events include infusion reactions, febrile neutropenia, fatigue, fluid retention, pneumonitis, cutaneous and nail toxicity, epiphora and lacrimal duct stenosis, gastrointestinal complications, and neuropathies. In this review, we explore these complications and how they can be effectively managed to improve patient quality of life during and following docetaxel therapy

    Management of bipolar disorder during pregnancy often involves medications with potential adverse effects, including risks to the mother and fetus. Although some specifics are known, many medications continue to have incompletely characterized reproductive safety profiles. Women with bipolar disorder who are planning pregnancy face challenging decisions about their treatment; careful risk-benefit discussions are necessary. With the goal of further informing these discussions, this article reviews the data currently available regarding medication safety in the management of bipolar disorder during pregnancy, with specific attention to lithium, valproic acid, lamotrigine, carbamazepine, and antipsychotic medications.

    Full Text Available Methotrexate (MTX is one of the most commonly used medicines in the treatment of psoriatic arthritis. The drug can produce steatosis and cirrhosis. Autoimmune hepatitis is a rare and serious adverse effect. We describe the case of a 53-year-old woman who developed autoimmune hepatitis after a long-term use of MTX for psoriatic arthritis. Hepatitis was completely resolved 4 months after stopping this drug. The pathophysiologic mechanisms of a drug-induced autoimmunity are unclear and complex. This report confirms the need to monitor liver enzymes carefully in patients using long-term treatment with MTX for psoriasis or rheumatoid arthritis.

    Polychlorinated-biphenyls (PCBs) were introduced in the late 1920s and used until the 1970s when they were banned in most countries due to evidence of environmental build-up and possible adverse health effects. However they still persist in the environment, indoors and in humans. Indoor air in contaminated buildings may confer airborne exposure markedly above background regional PCB levels. To date, no epidemiological studies have assessed the health effects from exposure to semi-volatile PCB...

    Early HIV detection and treatment decreases morbidity and mortality and reduces high-risk behaviors. Many Emergency Departments (EDs) have HIV screening programs as recommended by the Centers for Disease Control and Prevention. Recent federal legislation includes incentives for electronic health record (EHR) adoption. Our objective was to analyze the impact of conversion to EHR on a mature ED-based HIV screening program. A retrospective pre- and post-EHR implementation cohort study was conducted in a large urban, academic ED. Medical records were reviewed for HIV screening rates from August 2008 through October 2013. On 1 November 2010, a comprehensive EHR system was implemented throughout the hospital. Before EHR implementation, labs were requested by providers by paper orders with HIV-1/2 automatically pre-selected on every form. This universal ordering protocol was not duplicated in the new EHR; rather it required a provider to manually enter the order. Using a chi-squared test, we compared HIV testing in the 6 months before and after EHR implementation; 55,054 patients presented before, and 50,576 after EHR implementation. Age, sex, race, acuity of presenting condition, and HIV seropositivity rates were similar pre- and post-EHR, and there were no major patient or provider changes during this period. Average HIV testing rate was 37.7% of all ED patients pre-, and 22.3% post-EHR, a 41% decline (p implementation, and could have been improved with more thoughtful inclusion of existing human processes in its design.

    Full Text Available We evaluated the components of the Fuenzalida-Palacios antirabies vaccine, which is till used in most developing countries in human immunization for treatment and prophylaxis. This vaccine is prepared from newborn mouse brains at 1% concentration. Even though the vaccine is considered to have a low myelin content, it is not fully free of myelin or of other undesirable components that might trigger adverse effects after vaccination. The most severe effect is a post-vaccination neuroparalytic accident associated with Guillain-Barré syndrome. In the present study we demonstrate how the vaccines produced and distributed by different laboratories show different component patterns with different degrees of impurity and with varying protein concentrations, indicating that production processes can vary from one laboratory to another. These differences, which could be resolved using a better quality control process, may affect and impair immunization, with consequent risks and adverse effects after vaccination. We used crossed immunoelectrophoresis to evaluate and demonstrate the possibility of quality control in vaccine production, reducing the risk factors possibly involved in these immunizing products.

    Topical steroids are known for their anti-inflammatory properties and are commonly prescribed to treat many adverse skin conditions such as eczema and psoriasis. While these treatments are known to be effective, adverse effects including skin atrophy are common. In this study, the progression of these effects is investigated in an in vivo mouse model using multimodal optical microscopy. Utilizing a system capable of performing two-photon excitation fluorescence microscopy (TPEF) of reduced nicotinamide adenine dinucleotide (NADH) to visualize the epidermal cell layers and second harmonic generation (SHG) microscopy to identify collagen in the dermis, these processes can be studied at the cellular level. Fluorescence lifetime imaging microscopy (FLIM) is also utilized to image intracellular NADH levels to obtain molecular information regarding metabolic activity following steroid treatment. In this study, fluticasone propionate (FP)-treated, mometasone furoate (MF)-treated and untreated animals were imaged longitudinally using a custom-built multimodal optical microscope. Prolonged steroid treatment over the course of 21 days is shown to result in a significant increase in mean fluorescence lifetime of NADH, suggesting a faster rate of maturation of epidermal keratinocytes. Alterations to collagen organization and the structural microenvironment are also observed. These results give insight into the structural and biochemical processes of skin atrophy associated with prolonged steroid treatment. PMID:26739196

    Atopic eczema is a chronic inflammatory disease affecting about 30% of Australian and New Zealand children. Severe eczema costs over AUD 6000/year per child in direct medical, hospital and treatment costs as well as time off work for caregivers and untold distress for the family unit. In addition, it has a negative impact on a child's sleep, education, development and self-esteem. The treatment of atopic eczema is complex and multifaceted but a core component of therapy is to manage the inflammation with topical corticosteroids (TCS). Despite this, TCS are often underutilised by many parents due to corticosteroid phobia and unfounded concerns about their adverse effects. This has led to extended and unnecessary exacerbations of eczema for children. Contrary to popular perceptions, (TCS) use in paediatric eczema does not cause atrophy, hypopigmentation, hypertrichosis, osteoporosis, purpura or telangiectasia when used appropriately as per guidelines. In rare cases, prolonged and excessive use of potent TCS has contributed to striae, short-term hypothalamic-pituitary-adrenal axis alteration and ophthalmological disease. TCS use can also exacerbate periorificial rosacea. TCS are very effective treatments for eczema. When they are used to treat active eczema and stopped once the active inflammation has resolved, adverse effects are minimal. TCS should be the cornerstone treatment of atopic eczema in children.

    Abstract Recent studies have demonstrated that atrial fibrillation significantly increases the risk of adverse clinical outcomes in high cardiovascular disease risk subjects. Application of renin–angiotensin–aldosterone system blockers for prevention of recurrence of atrial fibrillation and adverse clinical outcomes in subjects with atrial fibrillation is a theoretically appealing concept. However, results of clinical trials evaluating the effect of renin–angiotensin–aldosterone blockers on adverse clinical outcomes in high cardiovascular disease risk subjects with atrial fibrillation remain inconclusive. A pooled study of 6 randomized controlled trials assessing the efficacy of renin–angiotensin–aldosterone blockers on subjects with atrial fibrillation was performed. A total of 6 randomized controlled trials enrolled a total of 53,510 patients followed for 1 to 5 years. RAAS blockade therapy was associated with 14% reduction in the incidence of heart failure (OR: 0.86, [95%CI: 0.76– 0.97], P=0.018) and 17% reduction in the incidence of CVE (OR: 0.83, [95%CI: 0.70–0.99], P = 0.038). The corresponding decline in absolute risk against heart failure (ARR: 1.4%, [95%CI: 0.2–2.6%], P = 0.018) and CVE (ARR: 3.5%, [95%CI: 0.0–6.9%], P = 0.045) in the AF group was much higher than the non-AF group for heart failure (ARR: 0.4%, [95%CI: 0.0–0.7%], P = 0.057) and CVE (ARR: 1.6%, [95%CI: –0.1% to 3.3%], P = 0.071). No significant effect was noted on all-cause or cardiovascular mortality, stroke, or myocardial infarction. This study suggests that RAAS blockade offers protection against heart failure and cardiovascular events in high cardiovascular disease risk subjects with atrial fibrillation. PMID:27368043

  19. A review of the adverse side effects associated with antipsychotics as related to their efficacy.

    2014-11-01

    Since the introduction of antipsychotic medication for the treatment of psychosis, a wide range of different types of antipsychotic drugs have been developed while their side effects have become evident. The side effects of both the typical and atypical generation of antipsychotics have important consequences for the quality of life of recipients, stigma experienced and also the level of care of patients. It is well acknowledged that the side effects of antipsychotics reduce compliance with the medication. In this review the data for an association between typical and atypical antipsychotics and the main side effects that are well-supported in the literature was explored: weight gain and associated metabolic effects; extrapyramidal symptoms and tardive dyskinesia; prolactin elevation and associated sexual effects; QTc elongation; and a group of miscellaneous side effects. It has been demonstrated that the production of adverse effects following the use of antipsychotic medication differs widely both between atypical and typical drugs but also within these subgroups. Considering the wide range of antipsychotics available amongst both groups and the differing effects they have on patients in terms of side effects, there is reason to believe that a more personalised approach to antipsychotic treatment should be considered. Additionally, screening for risk factors, screening for the appearance of side effects, as well as good communication with patients about the side effects and other options available are important tasks for clinicians in order to optimise concordance with medication.

    Determining the effect of space travel on the human immune system has proven to be extremely challenging. Limited opportunities for in-flight studies, varying mission durations, technical and logistical obstacles, small subject numbers, and a broad range of potential assays have contributed to this problem. Additionally, the inherent complexity of the immune system, with its vast array of cell populations, sub-populations, diverse regulatory molecules, and broad interactions with other physiological systems, makes determining precise variables to measure very difficult. There is also the challenge of determining the clinical significance of any observed immune alterations. Will such a change lead to disease, or is it a transient subclinical observation related to short-term stress? The effect of this problem may be observed by scanning publications associated with immunity and spaceflight, which began to appear during the 1970s. Although individually they are each valid studies, the comprehensive literature to date suffers from widely varying sampling methods and assay techniques, low subject counts, and sometimes a disparate focus on narrow aspects of immunity. The most clinically relevant data are derived from in-flight human studies, which have demonstrated altered cell-mediated immunity and reactivation of latent herpes viruses. Much more data are available from post-flight testing of humans, with clear evidence of altered cytokine production patterns, altered leukocyte distribution, continued latent viral reactivation, and evidence of dramatically altered virus-specific immunity. It is unknown if post-flight assessments relate to the in-flight condition or are a response to landing stress and readaptation. In-flight culture of cells has clearly demonstrated that immune cells are gravity-sensitive and display altered functional characteristics. It is unknown if these data are related to in vivo immune cell function or are an artifact of microgravity culture

    Full Text Available Purpose: Adverse drug reactions (ADRs are adverse consequences of drug therapy. ADRs are representing a major concern of health systems in terms of early recognition, proper management and prevention. Under reporting of Adverse Drug Reactions (ADRs is a common problem in Pharmacovigilance programs. Poor perceptions of doctors about ADRs and risk management have contributed to high rate of ADR under-reporting in India. Underreporting has also been attributed to lack of time to doctor, misconceptions about spontaneous reporting and lack of information on how to report, where to report and a lack of availability of report forms, and also physicians' attitudes to ADRs. The objective of our study was to evaluate the knowledge, attitude and practices (KAP of health care professional towards Pharmacovigilance and adverse drug reactions in a tertiary care hospital, Bhavnagar, Gujarat, India. Methods: A cross-sectional questionnaires based study was carried out in Post graduate students and faculties of tertiary care hospital attached with Govt. Medical College, Bhavnagar, Gujarat. Post graduate students and faculties of different clinical subjects working in the tertiary care teaching hospital, Bhavnagar, Gujarat (India were enrolled and present throughout in study. 22 questionnaires about knowledge, attitude and practices towards ADRs and Pharmacovigilance were developed and peer viewed of all questionnaires by expert faculties from Pharmacology department. We were contacted directly to post graduate students and faculties of respective clinical department, questionnaires were distributed, 30 minutes time given to filled form. Any clarification and extra time was needed, provided to them. The filled KAP questionnaires were analyzed in question wise and their percentage value was calculated by using Microsoft excel spread sheet and online statistical software.

    Gratitude has robust associations with multiple aspects of well-being. However, little research has explored whether the psychological benefits of gratitude extend to body image. We used a repeated measures experimental design to test whether a brief period of grateful reflection would buffer the adverse effect of exposure to thin-ideal media. Female undergraduates (N=67) completed three sessions one week apart. The conditions were specifically designed to isolate (a) the effects of viewing thin models on body dissatisfaction and (b) the moderating effect of grateful contemplation. Results showed that body dissatisfaction scores were lower for women who engaged in a brief period of grateful contemplation before viewing photographs of thin models than for women who reflected upon life hassles before viewing the same photographs. The magnitude of this decrease depended on BMI. Gratitude offers an innovative direction for future research directed toward helping women to accept their bodies. PMID:24958659

  5. Effects of roughness and adverse pressure gradient on the turbulence structure

    International Nuclear Information System (INIS)

    Highlights: • Adverse pressure gradient diminished the size of the hairpin packet over the smooth wall. • Adverse pressure gradient produced more intense ejection, sweep and interaction motions over smooth and rough walls. • The turbulence structure over the k-type rough wall is larger compared to the smooth wall. -- Abstract: The manuscript presents an experimental study of turbulent flows over smooth and rough walls in a channel that consists of an upstream parallel section to produce a fully developed channel flow and a diverging section to produce an adverse pressure gradient (APG) flow. The roughness element consists of two-dimensional transverse square ribs of nominal height, k = 3 mm that were spaced to produce pitch-to-height ratio of p/k = 2 and 8, corresponding to d-type and k-type rough walls. A particle image velocimetry system was used to conduct detailed velocity measurements over the smooth and rough walls in both the parallel and diverging sections. The mean defect velocity and Reynolds stresses as well as Galilean decomposition, quadrant decomposition, two-point velocity correlation and linear stochastic estimation were used to document the salient effects of APG and wall roughness on the flows. The results indicated that APG significantly augments turbulence level compared to the flows in the parallel section. The flow fields were populated with vortex cores that formed hairpin vortex packets. The packets were inclined at shallow angles relative to the wall as revealed by the two-point velocity correlation. The quadrant analysis revealed that the ejections, sweeps, and inward and outward interaction motions associated with the structures were influenced by roughness and APG. The existence of structures was further supported by linear stochastic estimates conditioned on the prograde vortices

    We examined parent-reported adverse childhood experiences (ACEs) and associated outcomes among American Indian and Alaska Native (AI/AN) children aged 0–17 years from the 2011-2012 National Survey of Children's Health. Bivariate and multivariable analyses of cross-sectional data on 1,453 AI/AN children and 61,381 non-Hispanic White (NHW) children assessed race-based differences in ACEs prevalence and differences in provider-diagnosed chronic emotional and developmental conditions, health characteristics, reported child behaviors, and health services received as a function of having multiple ACEs. AI/AN children were more likely to have experienced 2+ ACEs (40.3% versus 21%), 3+ ACEs (26.8% versus 11.5%), 4+ ACEs (16.8% versus 6.2%), and 5+ ACEs (9.9% versus 3.3%) compared to NHW children. Prevalence rates for depression, anxiety, and ADHD were higher among AI/AN children with 3+ ACEs (14.4%, 7.7%, and 12.5%) compared to AI/ANs with fewer than 2 ACEs (0.4%, 1.8%, and 5.5%). School problems, grade failures, and need for medication and counseling were 2-3 times higher among AI/ANs with 3+ ACEs versus the same comparison group. Adjusted odds ratio for emotional, developmental, and behavioral difficulties among AI/AN children with 2+ ACEs was 10.3 (95% CI = 3.6–29.3). Race-based differences were largely accounted for by social and economic-related factors. PMID:27529052

    Directory of Open Access Journals (Sweden)

    Ata Mahmoodpoor

    2015-04-01

    Full Text Available Once admired for its supposed safety, nitrous oxide is presently blamed to increase adverse cardiovascular effects through augmenting plasma homocysteine concentrations (1, 2. Hemodynamic alterations following the administration of nitrous oxide are extremely complicated and sometimes contradictory. Enhanced venous return, arterial pressure, pulmonary and systemic vascular resistance, cardiac output, pupillary dilation and diaphoresis occur under nitrous oxide administration consistent with sympathomimetic properties of nitrous oxide (3. Conversely, reductions in arterial pressure are also probable, especially in patients with coronary artery disease. Nitrous oxide can also depress myocardial contractility due to decreased availability of Ca2+ for contractile activation; yet, myocardial relaxation kinetics remains intact (4. In the presence of a volatile anesthetic, nitrous oxide decreases MVO2 (Myocardial oxygen consumption and myocardial O2 extraction which may exacerbate myocardial ischemia during concomitant reductions in arterial pressure in patients with coronary artery disease. Consequently, it could be conjectured that probable adverse cardiovascular effects following nitrous oxide administration are variable and consequent of a multi-variable phenomenon rather than a single variable such as increased levels of homocysteine. Studied purely focusing on the effects of nitrous oxide are difficult to conduct due to the numerous confounding factors.In a study by Myles et al., hyperhomocysteinemia has been introduced as the source of the adverse cardiovascular effects of nitrous oxide. However, in this study, increased inspired oxygen concentrations were used to overcome arterial desaturation (1. Given the fact that a constant volume and flow rates are used throughout the anesthesia in a particular patient, increasing the concentrations of oxygen would be associated with decreased delivered nitrous oxide and volatile anesthetic concentrations

    The effect of particulate matter on construction materials have been studied under laboratory conditions. For testing the adverse effects of diesel soot and particulate matter on stone and concrete a small scale laboratory exposure chamber was constructed. Blocks of 9 different stone types and concrete was placed in the chamber and an exhaust pipe of diesel engine was diverted into the system. Tested stones included: porous limestone, cemented non-porous limestone, travertine, marble, rhyolite tuff, andesite and granite. The engine was operated for 10 hours and the produced particulate matter was diverted directly to the surface of the material specimens of 3 cm in diameter each. Working parameters of the engine were controlled; the composition of the exhaust gas, smoke value and temperature were continuously measured during the test. Test specimens were documented and analysed prior to exposure and after the exposure test. Parameters such colorimetric values, weight, surface properties, mineralogical compositions of the test specimens were recorded. The working temperature was in the order of 300°C-320°C. The gas concentration was in ppm as follows: 157 CO; 5.98 CO2, 34.3 THC; 463 NOx; 408 NO; 12.88 O2. Our tests have demonstrated that significant amount of particulate matter was deposited on construction materials even at a short period of time; however the exposure was very intense. It also indicates that that the interaction of particulate matter and aerosol compounds with construction materials in urban areas causes rapid decay and has an adverse effect not only on human health but also on built structures.

    Multipotent mesenchymal stromal cells [also referred toas mesenchymal stem cells (MSCs)] are a heterogeneoussubset of stromal cells. They can be isolated from bonemarrow and many other types of tissue. MSCs arecurrently being tested for therapeutic purposes (i.e.,improving hematopoietic stem cell engraftment, managinginflammatory diseases and regenerating damagedorgans). Their tropism for tumors and inflamed sites andtheir context-dependent potential for producing trophicand immunomodulatory factors raises the question asto whether MSCs promote cancer and/or infection. Thisarticle reviews the effect of MSCs on tumor establishment,growth and metastasis and also susceptibility to infectionand its progression. Data published to date shows aparadoxical effect regarding MSCs, which seems todepend on isolation and expansion, cells source anddose and the route and timing of administration.

    Despite the significant contributions from previous studies about the prevalence of problematic Internet use (PIU) among adolescents in Europe, important questions remain regarding adverse consequences of PIU. This study aims to assess the relation between duration of Internet use and adverse psychosocial effects among adolescents from six European countries. The final sample included 7,351 adolescents (50.8% male and 49.2% female; mean age: 14.6±1.90) recruited from randomly selected schools within the six study sites. Results showed that 12.9% of adolescents used Internet more than 20 hours per week. There was a significant relationship between duration of Internet use and frequency of alcohol, tobacco, cannabis and other illegal drug use. Duration of Internet use is also significantly associated with school problems, with use of slot machines and with other psychosocial problems. These findings highlight the need to strengthen preventive efforts for reducing PIU and related consequences among adolescents. Key Words: Internet, adolescents, psychosocial problems. PMID:25314040

    Carrageenan (CRG) is a family of natural polysaccharides derived from seaweeds and has widely been used as food additives. In the past decade, owing to its attractive physicochemical properties, CRG has been developed into versatile biomaterials vehicles for drug delivery. Nevertheless, studies also emerged to reveal its adverse effects on the biological system. In this review, we critically appraise the latest literature (two thirds since 2008) on the development of CRG-based pharmaceutical vehicles and the perspective of using CRG for broader biomedical applications. We focus on how current strategies exploit the unique gelling mechanisms, strong water absorption and abundant functional groups of the three major CRG varieties. Notably, CRG-based matrices are demonstrated to increase drug loading and drug solubility, enabling release of orally administrated drugs in zero-order or in a significantly prolonged period. Other amazing features, such as pH-sensitivity and adhesive property, of CRG-based formulations are also introduced. Finally, we discuss the adverse influence of CRG on the human body and then suggest some future directions for the development of CRG-based biomaterials for broader applications in biomedicine.

  19. A Study on the Adverse Effect of AOVs in AFWS Recirculation Paths on Plant Safety

    International Nuclear Information System (INIS)

    Auxiliary feedwater system (AFWS) recirculation flow paths adopted air operated valves (AOVs) which could fail close on loss of instrument air (LOIA) event. So the AOVs and recirculation paths are closed on LOIA event, which could result in Auxiliary feedwater (AFW) pump(s) damage, which contributes greatly to core damage frequency (CDF).. On February 2002, the USNRC issued an inspection finding related to potential common cause failure of AOVs in AFWS recirculation flow paths on loss of instrument air system in Point Beach nuclear power plant (Pt. Beach). The AOVs have been removed from AFWS recirculation paths in the design of Korea standard nuclear power plant (KSNP). So, there is no possibility of above mentioned failure event in KSNP. It would be beneficial to evaluate the significance of adverse effect of AOVs in AFWS recirculation paths to realize the importance of maintaining AFWS recirculation paths always open. In this study, the AFWS modeling of Ulchin unit 3 and 4 was modified to model the AOVs in AFW recirculation flow paths to evaluate the change in CDF, which is caused by the adverse effect of AOV with operation mode of 'fails close' on LOIA event. It is concluded that the existence of AOV with 'fail close' design in AFWS MDP recirculation paths results in CDF increase of 131%, which is significant adverse effect on plant safety.. In this regard, the improved Westinghouse design and KSNP design had removed the AOVs from AFWS MDP recirculation paths. However, a couple of units with old Westinghouse design, Kori 1 and 2, still have AOVs in AFWS MDP recirculation paths and throttle back operation of AFWS is in effect. Although those AOVs adopt 'fail open' design to prevent above mentioned inadvertent closure, considering the big increase in CDF, there still exists considerable risk from the possibility of 'failure to open' during this throttle back operation. Therefore, it is strongly recommended that any

    Full Text Available Gian Maria Pacifici Medical School, Department of Translational Research and New Technologies in Medicine and Surgery, Section of Pharmacology, University of Pisa, Pisa, Italy Objective: The objective of this study was to evaluate the extent of renal adverse effects caused by ibuprofen or indomethacin in order to choose the safer drug to administer to preterm infants. Methods: The following three parameters of renal function were taken into consideration: 1 the urine output; 2 the serum creatinine concentration; and 3 the frequency of oliguria. The bibliographic search was performed using PubMed and Embase databases as search engines. Results: Urine output ranged from 3.5±1.2 to 4.0±1.4 mL/kg/h after ibuprofen treatment, and from 2.8±1.1 to 3.6±1.4 mL/kg/h after indomethacin treatment. The values for ibuprofen are significantly (P<0.05 higher than those for indomethacin. The serum creatinine concentrations ranged from 0.98±0.24 to 1.48±0.2 mg/dL after ibuprofen treatment, and from 1.06±0.24 and 2.03±2.10 mg/dL after indomethacin treatment. The values for ibuprofen are significantly (P<0.05 lower than those for indomethacin. The frequency of oliguria ranged from 1.0% to 9.6% (ibuprofen and from 14.8% to 40.0% (indomethacin, and was significantly lower following ibuprofen than indomethacin administration. In infants with body weight lower than 1,000 g, oliguria appeared in 5% (ibuprofen and 40% (indomethacin; P=0.02. Conclusion: Indomethacin is associated with more severe renal adverse effects than ibuprofen. Ibuprofen is less nephrotoxic than indomethacin and should be used to treat patent ductus arteriosus in preterm infants. Immaturity increases the frequency of adverse effects of indomethacin. Keywords: ibuprofen, indomethacin, patent-ductus-arteriosus, renal-side-effects

    Full Text Available Symbiotic association between arbuscular mycorrhizal (AM species and host plant roots improves plant growth and protects them from several abiotic stress factors. In the present study, the effect of Glomus mosseae and Glomus fasciculatum as an individual inoculation and in combination was studied on two legumes (Glycine max and Cyamopsis tetragonoloba under soil salinity stress gradient [1.04 (control to 8.26 dS/m]. Individual and co-inoculation of both the AM fungi alleviated adverse salt effect, with improvement in plant dry weight matter and biochemical parameters. However, these two isolates worked better in combination with respect to higher accumulation of soluble carbohydrate, reducing sugar, protein, proline concentration etc. C. tetragonoloba showed better response as compared to G. max in relation to improvement in nutritional profile under salt stress after AM treatment. As compared to non-mycorrhizal counterparts, co-inoculation with G. mosseae and G. fasciculatum in C. tetragonoloba enhanced total chlorophyll (14.83% at soil salinity of 3.78 dS/m, soluble carbohydrate (17.26% at soil salinity of 5.94 dS/m, proline (8.79% at soil salinity of 3.78 dS/m while exposed to different soil salinity levels. Also, co-colonization with both the isolates showed more root colonization (% and may be responsible for the better effect in salt stress alleviation. Electrolyte leakage of mycorrhizal plants was lowered at soil salinity gradient of 2.10 to 8.26 dS/m and hence, maintained membrane stability. These two isolates can be utilized as bio-inoculant in alleviation of adverse salt effect in soil in association with the two test legume plants.

    Comprehensively documents potential late effects in all the normal tissue sites in the human body. Considers in detail the detection, diagnosis, management and prevention of effects and discusses prognostic outcomes. Clearly presents radiation risk factors and interactions with chemotherapy effects. Provides the most current evidence-based medicine for cancer care survivorship guidelines. The literature on the late effects of cancer treatment is widely scattered in different journals since all major organ systems are affected and management is based on a variety of medical and surgical treatments. The aim of ALERT - Adverse Late Effects of Cancer Treatment is to offer a coherent multidisciplinary approach to the care of cancer survivors. The central paradigm is that cytotoxic multimodal therapy results in a perpetual cascade of events that affects each major organ system differently and is expressed continually over time. Essentially, radiation and chemotherapy are intense biologic modifiers that allow for cancer cure and cancer survivorship but accelerate senescence of normal tissues and increase the incidence of age-related diseases and second malignant tumors. Volume 2 of this two-volume work comprehensively documents potential late effects in all the normal tissue anatomic sites in the human body. The detection, diagnosis, management and prevention of effects are all considered in detail, and prognostic outcomes are discussed. Radiation risk factors and interactions with chemotherapy effects are clearly presented. The text is accompanied by numerous supportive illustrations and tables.

    A comparative assessment of the effectiveness of different prophylactic procedures to prevent the adverse effects of weightlessness is presented. It is concluded that: physical training is most effective but no single method by itself produces the full effect, and an adjustment of regimes to one another enhances the effect. The approved complex of prophylactic procedures affected basic changes occurring in hypokinesia: deficit of muscular activity, no or reduced BP hydrostatic component, reduced volume of blood circulation, reduced hydration level, and the application of various prophylactic complexes during 49 day antiorthostatic hypodynamia eliminated or reduced the adverse effects of weightlessness in simulation.

    Oil and natural gas operations have been shown to contaminate surface and ground water with endocrine-disrupting chemicals. In the current study, we fill several gaps in our understanding of the potential environmental impacts related to this process. We measured the endocrine-disrupting activities of 24 chemicals used and/or produced by oil and gas operations for five nuclear receptors using a reporter gene assay in human endometrial cancer cells. We also quantified the concentration of 16 of these chemicals in oil and gas wastewater samples. Finally, we assessed reproductive and developmental outcomes in male C57BL/6J mice after the prenatal exposure to a mixture of these chemicals. We found that 23 commonly used oil and natural gas operation chemicals can activate or inhibit the estrogen, androgen, glucocorticoid, progesterone, and/or thyroid receptors, and mixtures of these chemicals can behave synergistically, additively, or antagonistically in vitro. Prenatal exposure to a mixture of 23 oil and gas operation chemicals at 3, 30, and 300 μg/kg · d caused decreased sperm counts and increased testes, body, heart, and thymus weights and increased serum testosterone in male mice, suggesting multiple organ system impacts. Our results suggest possible adverse developmental and reproductive health outcomes in humans and animals exposed to potential environmentally relevant levels of oil and gas operation chemicals.

    The transplantation of conventional human cell and tissue grafts, such as heart valve replacements and skin for severely burnt patients, has saved many lives over the last decades. The late eighties saw the emergence of tissue engineering with the focus on the development of biological substitutes that restore or improve tissue function. In the nineties, at the height of the tissue engineering hype, industry incited policymakers to create a European regulatory environment, which would facilitate the emergence of a strong single market for tissue engineered products and their starting materials (human cells and tissues). In this paper we analyze the elaboration process of this new European Union (EU) human cell and tissue product regulatory regime-i.e. the EU Cell and Tissue Directives (EUCTDs) and the Advanced Therapy Medicinal Product (ATMP) Regulation and evaluate its impact on Member States' health care systems. We demonstrate that the successful lobbying on key areas of regulatory and policy processes by industry, in congruence with Europe's risk aversion and urge to promote growth and jobs, led to excessively business oriented legislation. Expensive industry oriented requirements were introduced and contentious social and ethical issues were excluded. We found indications that this new EU safety and health legislation will adversely impact Member States' health care systems; since 30 December 2012 (the end of the ATMP transitional period) there is a clear threat to the sustainability of some lifesaving and established ATMPs that were provided by public health institutions and small and medium-sized enterprises under the frame of the EUCTDs. In the light of the current economic crisis it is not clear how social security systems will cope with the inflation of costs associated with this new regulatory regime and how priorities will be set with regard to reimbursement decisions. We argue that the ATMP Regulation should urgently be revised to focus on delivering

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

    Cooper, Ziva D

    2016-05-01

    Although several chemical structural classes of synthetic cannabinoids (SCs) were recently classified as Schedule I substances, rates of use and cases of serious toxic effects remain high. While case reports and media bring attention to severe SC toxicity, daily SC use resulting in dependence and withdrawal is a significant concern that is often overlooked when discussing the risks of these drugs. There is a rich literature on evidence-based approaches to treating substance use disorders associated with most abused drugs, yet little has been published regarding how to best treat symptoms related to SC dependence given its recency as an emerging clinically significant issue. This review provides a background of the pharmacology of SCs, recent findings of adverse effects associated with both acute intoxication and withdrawal as a consequence of daily use, and treatment approaches that have been implemented to address these issues, with an emphasis on pharmacotherapies for managing detoxification. In order to determine prevalence of use in cannabis smokers, a population at high risk for SC use, we obtained data on demographics of SC users, frequency of use, and adverse effects over a 3.5-year period (2012-2015) in the New York City metropolitan area, a region with a recent history of high SC use. While controlled studies on the physiological and behavioral effects of SCs are lacking, it is clear that risks associated with using these drugs pertain not only to the unpredictable and severe nature of acute intoxication but also to the effects of long-term, chronic use. Recent reports in the literature parallel findings from our survey, indicating that there is a subset of people who use SCs daily. Although withdrawal has not been systematically characterized and effective treatments have yet to be elucidated, some symptom relief has been reported with benzodiazepines and the atypical antipsychotic, quetiapine. Given the continued use and abuse of SCs, empirical studies

    Full Text Available We present a case of complete heart block (CHB in a 58-year-old female patient with acute myeloid leukemia (AML with no past history of cardiac disease, who received caspofungin in the treatment of disseminated fungal infection. To our knowledge, this is the first case of CHB associated with caspofungins. Subsequent to induction chemotherapy the patient developed invasive pulmonary aspergillosis with sudden tachypnea, dyspnoea, fever, bilateral pulmonary infiltrates and acute respiratory insufficiency consequent to neutropenia with ANC<500. During the first dose of antifungal therapy with caspofungins, she developed complete atrioventricular block and cardiac arrest. Complete heart block is an unusual adverse effect of caspofungins which has not been reported previously. Caspofungins release histamine in peripheral blood cells, so possible histamine-mediated symptoms ranging from severe fatal anaphylaxis can occur. These data suggest that infusion-related reactions associated with caspofungin may be mediated by histamine release secondary to caspofungin therapy.

    Worldwide, the benefits of combined antiretroviral (ARV) therapy in morbidity and mortality due to perinatally acquired human immunodeficiency virus infection are beyond question and outweigh the toxicity these drugs have been associated with in HIV-infected children and adolescents to date. In puberty, abnormal body fat distribution is stigmatizating and leads to low adherence to ARV treatment. The other metabolic comorbidities (mitochondrial toxicity, dyslipidemias, insulin resistance and low bone mineral density) and renal toxicity, albeit nonsymptomatic in most children, are increasingly being reported and potentially put this population at risk for early cardiovascular or cerebrovascular atherosclerotic disease, diabetes, pathologic fractures or premature renal failure in the third and fourth decades of life. Evidence from available studies is limited because of methodological limitations and also because of several HIV-unrelated factors influencing, to some degree, the development of these conditions. Current recommendations for the prevention, diagnosis, monitoring and treatment of metabolic and renal adverse effects in HIV-children and adolescents are based on adult studies, observational pediatric studies and experts' consensus. Healthy lifestyle habits (regarding diet, exercise and refraining from toxic substances) and wise use of ARV options are the only preventive tools for the majority of patients. Should abnormal findings arise, switches in one or more ARV drugs have proved useful. Specific therapies are also available for some of these comorbidities, although the experience in the pediatric age is still very scarce. We aim to summarize the epidemiological, clinical and therapeutic aspects of metabolic and renal adverse effects in vertically HIV-infected children and adolescents. PMID:25629891

    2016-06-01

    Pharmacotherapy directed toward reducing body weight may provide benefits for both curbing obesity and lowering the risk of obesity-associated comorbidities; however, many weight loss medications have been withdrawn from the market because of serious adverse effects. Examples include pulmonary hypertension (aminorex), cardiovascular toxicity, e.g. flenfluramine-induced valvopathy, stroke [phenylpropanolamine (PPA)], excess non-fatal cardiovascular events (sibutramine), and neuro-psychiatric issues (rimonabant; approved in Europe, but not in the USA). This negative experience has helped mould the current drug development and approval process for new anti-obesity drugs. Differences between the US Food and Drug Administration (FDA) and the European Medicines Agency, however, in perceptions of risk-benefit considerations for individual drugs have resulted in discrepancies in approval and/or withdrawal of weight-reducing medications. Thus, two drugs recently approved by the FDA, i.e. lorcaserin and phentermine + topiramate extended release, are not available in Europe. In contrast, naltrexone sustained release (SR)/bupropion SR received FDA approval, and liraglutide 3.0 mg was recently approved in both the USA and Europe. Regulatory strategies adopted by the FDA to manage the potential for uncommon but potentially serious post-marketing toxicity include: (i) risk evaluation and mitigation strategy programmes; (ii) stipulating post-marketing safety trials; (iii) considering responder rates and limiting cumulative exposure by discontinuation if weight loss is not attained within a reasonable timeframe; and (iv) requiring large cardiovascular outcome trials before or after approval. We chronicle the adverse effects of anti-obesity pharmacotherapy and consider how the history of high-profile toxicity issues has shaped the current regulatory landscape for new and future weight-reducing drugs.

  19. Serious adverse effects of gamma knife radiosurgery for mesial temporal lobe epilepsy

    International Nuclear Information System (INIS)

    Gamma knife radiosurgery (GKRS) for mesial temporal lobe epilepsy (MTLE) has been proposed as an alternative to surgical resection. We report serious adverse effects of the treatment after follow-up periods over 9 years in 11 patients treated with GKRS between 1997 and 2000. The target volume of the entorhinoamygdalohippocampectomy area was 4.8-17.1 ml. Marginal dose of 20-25 Gy to the 50% isodose was delivered. One patient was drowned after suffering seizure 7 months after GKRS. Two patients did not show any reduction in seizure frequency over 9 and 18 months. Both patients requested open surgery and became seizure-free postoperatively. Four of the other eight patients were classified as Engel's class I within 4 years after GKRS. One of the four patients experienced symptomatic radiation-induced cerebral edema transiently, one developed radiation necrosis and required surgery 5 years after GKRS, and one developed cognitive impairment with hemiparesis 10 years after GKRS. Magnetic resonance (MR) imaging showed a large cyst in the irradiated temporal lobe. This patient recovered fully after the cyst excision. Only one patient became seizure-free and antiepileptic drug-free without symptomatic radiation-induced complications. However, MR imaging revealed abnormal enhancement, cyst formation, and diffuse white matter change in the irradiated temporal lobe 9 years after GKRS. GKRS for MTLE causes adverse effects of delayed seizure remission and symptomatic radiation-induced complications. Therefore, GKRS cannot be considered as an ideal alternative to surgery for MTLE. Long-term follow-up studies including MR imaging with contrast medium are required for the patients even after successful control of seizures. (author)

  20. Adverse effects of radon and its progeny on immune system in rats

    International Nuclear Information System (INIS)

    Objective: To study adverse effects of inhaled radon and its progeny on immune system of rats. Methods: Sprague-Dawley rats were exposed to radon and its progeny at cumulative doses up to 66, 111 and 174 WLM (working level month), respectively. The numbers and types of cells in bronchoalveolar lavage fluids (BALF) were investigated. The spleen index was examined. The DNA migration in the thymus and spleen cells was detected with single cell gel electrophoresis(SCGE). RT-PCR was applied to determine the expression of IL-6 mRNA in BALF cells. Results: It was shown that the proportion of lymphocyte of the exposed groups was significantly lower than that of the control group while the proportion of granulocyte was higher than that of the control group (P<0.05). The distance of DNA migration in the thymus and spleen cells increased in the 174 WLM group. The spleen index of 111 WLM and 174 WLM groups decreased significantly compared with the control group. A high expression level of IL-6 mRNA in BALF cells was observed in the 174 WLM group (P<0.01) but there was no significant change in other two exposed groups compared with the control group. Conclusion: The results suggest that in certain dose range radon and its progeny have adverse effect on structure and function of immune system of rats by affecting the proportion of lymphocyte and granulocyte in BALF, decreasing spleen index, and damaging the DNA of the thymus and spleen cells.

    Since the 1970s anabolic androgenic steroids (AAS) have been abused at ever increasing rates in competitive athletics, in recreational sports and in bodybuilding. Exceedingly high doses are often consumed over long periods, in particular by bodybuilders, causing acute or chronic adverse side effects frequently complicated by additional polypharmacy. This review summarizes side effects on non-reproductive organs and functions; effects on male and female reproduction have been recently reviewed in a parallel paper. Among the most striking AAS side effects are increases in haematocrit and coagulation causing thromboembolism, intracardiac thrombosis and stroke as well as other cardiac disturbances including arrhythmias, cardiomyopathies and possibly sudden death. 17α-alkylated AAS are liver toxic leading to cholestasis, peliosis, adenomas and carcinomas. Hyperbilirubinaemia can cause cholemic nephrosis and kidney failure. AAS abuse may induce exaggerated self-confidence, reckless behavior, aggressiveness and psychotic symptoms. AAS withdrawal may be accompanied by depression and suicidal intentions. Since AAS abuse is not or only reluctantly admitted physicians should be aware of the multitude of serious side effects when confronted with unclear symptoms. PMID:26373946

    Previous studies have shown that socio-demographic factors, childhood socioeconomic status (CSES), childhood traumatic experiences (CTEs), social support and behavioral factors are associated with health and well-being in adulthood. However, the relative importance of these factors for mental health, health, and well-being has not been studied. Moreover, the mechanisms by which CTEs affect mental health, health, and well-being in adulthood are not clear. Using data from a representative sample (n = 12,981) of the adult population in Tromsø, Norway, this study examines (i) the relative contribution of structural conditions (gender, age, CSES, psychological abuse, physical abuse, and substance abuse distress) to social support and behavioral factors in adulthood; (ii) the relative contribution of socio-demographic factors, CSES, CTEs, social support, and behavioral factors to three multi-item instruments of mental health (SCL-10), health (EQ-5D), and subjective well-being (SWLS) in adulthood; (iii) the impact of CTEs on mental health, health, and well-being in adulthood, and; (iv) the mediating role of adult social support and behavioral factors in these associations. Instrumental support (24.16%, p Psychological abuse was relatively more important for mental health (12.13%), health (7.01%), and well-being (9.09%), as compared to physical abuse, and substance abuse distress. The subjective assessment of childhood financial conditions was relatively more important for mental health (6.02%), health (10.60%), and well-being (20.60%), as compared to mother's and father's education. CTEs were relatively more important for mental health, while, CSES was relatively more important for health and well-being. Respondents exposed to all three types of CTEs had a more than two-fold increased risk of being mentally unhealthy (RRTotal Effect = 2.75, 95% CI: 2.19–3.10), an 89% increased risk of being unhealthy (RRTotal Effect = 1.89, 95% CI: 1.47–1.99), and a 42% increased

  4. Some effects of favorable and adverse electric fields on pool boiling in dielectric fluids

    International Nuclear Information System (INIS)

    The effects of the application of an electric field on pool boiling in dielectric fluids were studied in this work.Two different geometries were used: one which is favorable to the bubble detachment (favorable electric field) and other which attract the bubbles toward the heater (adverse electric field).In the favorable electric field experiments, the void fraction and impact rate were calculated from the measured indicator function.Those parameters were obtained varying the probe-heater distance and the power to the heater.The results show a reduction of the void fraction with increasing applied voltage, probably caused by the combination of the dielectrophoretic force and a smaller bubble size due to the electric field application. Also, the impact rate decreases when a voltage is applied and the heat fluxes are close to the critical heat flux (CHF).On the other hand, the impact rate increases with voltage for moderate heat fluxes.Another interesting result is the approximately exponential decay of the void fraction and impact rate with the distance to the heater. Both the void fraction and the impact rate grow with heat flux if the heat fluxes are moderate, with or without applied voltage.For highest heat fluxes the void fraction still grows with heat flux if there are no applied electric fields while decreases with heat flux when there is an applied voltage. Similar behavior is observed in the impact rate.The boiling regimes was measured with adverse electric fields using two techniques.The heat transfer in the nucleate boiling regime was measured on an electrically powered heater.The results in these experiments show a reduction in the CHF of 10 % for saturation conditions and 10 kV of applied voltage, and a reduction of up to 40 % for 20 oC of liquid subcooling.The boiling curve corresponding to the transition and film boiling was performed with quenching experiments.An increase in the heat flux was achieved when an electric field was applied in spite of the

  6. Cutaneous adverse effect during concomitant therapy with phenytoin and holoencefalica radiotherapy

    International Nuclear Information System (INIS)

    Introduction: Phenytoin is one of anticonvulsant drugs (AC) which together with the Corticosteroids are used frequently in patients with intracranial tumors either early or metastatic; the association of treatments can cause adverse effects within which are skin reactions called erythema multiforme (EM) syndrome Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) whose incidence is 5 to 10%, with an increased risk are used when the AC associated with treatment with radiotherapy (RT).Case report: A 48 year old woman in whom primitive brain metastases were diagnosed breast cancer, so phenytoin, corticosteroids and performed RT presenting holoencefálica for such treatment maculo-papular skin reaction symmetrical onset zone Radiant treatment extension neck, thorax, abdomen and pelvis, oral mucositis, conjunctivitis and fever, which improved after stopping treatment altogether. Discussion: The clinical picture presented matches the description of the 30 Reported SJS / TEN in the literature with the use of AC and RT cases. The clinical course of the skin reactions in our patient represents the possible combined effect of phenytoin and RT as causative agents and analyzed the occurrence of side effects occurred in the third week of starting treatment with both therapeutic modalities such as what described in these reactions and improved frankly to stop treatment until disappear entirely. Cutaneous adverse reactions may occur as a complication severe in patients treated with RT and phenytoin and both treatments should suspend the first sign of side effects must continue once the patient recovered with AC radiant modifying drug treatment if necessary. There are differences of opinion regarding the prophylactic use of drug therapy in patients with AC intracranial tumors both early and metastatic. The American Academy of Neurology held a consensus in 2000 whose recommendations are non-routine use of AC in patients diagnosed intracerebral tumor that has not

    Research was conducted to evaluate conversations about epilepsy between community-based neurologists and patients. Adverse effects of antiepileptic drugs and mood/behavioral issues were infrequently discussed, and neurologists and patients disagreed about these issues postvisit. Follow-up research was conducted to assess the impact of a previsit assessment tool on discussions of epilepsy. Twenty neurologists reviewed a tool incorporating questions from validated instruments (Adverse Events Profile [AEP] and Neurological Disorders Depression Inventory for Epilepsy [NDDI-E]). Naturally occurring interactions between neurologists and 60 patients were recorded. Neurologists and patients were interviewed separately. All components were transcribed and analyzed using sociolinguistics. Using the previsit assessment tool increased the number of discussions about adverse effects and mood/behavioral issues and increased neurologist-patient agreement about issues postvisit. Visit length did not increase significantly when the tool was used. Ten months after follow-up research, 50% of neurologists reported continuing to use the tool in everyday practice with patients with epilepsy. PMID:21967731

    Inhaled, intranasal, and cutaneous steroids are prescribed by physicians for a plethora of disease processes including asthma and rhinitis. While the high efficacy of this class of medication is well known, the wide range of adverse effects, both local and systemic, is not well elucidated. It is imperative to monitor total steroid burden in its varied forms as well as tracking for possible side effects that may be caused by a high cumulative dose of steroids. This review article highlights the adverse effects of different steroid modalities as well as suggests a monitoring tool to determine steroid totality and side effects. PMID:27207481

    Wogonin, a flavone in the roots of Scutellaria baicalensis, reduced etoposide-induced apoptotic cell death in normal cells, such as bone marrow cells and thymocytes. On the other hand, wogonin potentiated the proapoptotic or cytotoxic action of etoposide in tumor cells, such as Jurkat, HL-60, A549, and NCI-H226. These contradictory actions of wogonin on apoptosis are distinguished by normal or cancer cell types. Wogonin had no effect on apoptosis induced by other anticancer agents in the tumor cells. Thus, the potentiation effect of wogonin was observed only in etoposide-induced apoptosis in tumor cells. In a functional assay for P-glycoprotein (P-gp), wogonin suppressed excretion of calcein, a substrate for P-gp, in these tumor cells. Moreover, wogonin decreased the excretion of radiolabeled etoposide and accordingly increased intracellular content of this agent in the cells. P-gp inhibitors showed a similar potentiation effect on etoposide-induced apoptosis in these tumor cells. Thus, wogonin is likely to potentiate the anticancer action of etoposide due to P-gp inhibition and accumulation of this agent. These findings suggest that wogonin may be a useful chemotherapeutic adjuvant to potentiate the pharmacological action of etoposide and ameliorate its adverse effects. PMID:20658136

    The cost of photovoltaic (PV) energy is reduced by increasing solar cell power conversion efficiency and decreasing manufacture cost. An effective way of lowering the cost of Si thin film solar cells (TFSC) is to grow panels on large-area substrates. In this paper we study the effect of air residual to Si TFSC grown on 5.7 m{sup 2} glass in plasma-enhanced chemical vapor deposition (PECVD) chambers. Structural and chemical analysis show that oxygen incorporated into the Si films behaved as impurity dopant in the hydrogenated microcrystalline Si ({mu}c-Si) layers and reduced the efficiency of amorphous Si (a-Si)/{mu}c-Si tandem junction solar cells when the film had oxygen concentration >2 x 10{sup 19} atoms/cm{sup 3}. Higher oxygen content further suppressed the {mu}c-Si crystallization. We found that hydrogen plasma treatment of process chamber before Si film deposition effectively reduced the adverse effects of air exposure and improved both film quality and solar cell performance. The hydrogen-treated chamber produced contamination-free, solar cells with consistent, initial efficiency >10%. (author)

    Effects of fullerene-spiked sediment on a benthic organism, Lumbriculus variegatus (Oligochaeta), were investigated. Survival, growth, reproduction, and feeding rates were measured to assess possible adverse effects of fullerene agglomerates produced by water stirring and then spiked to a natural sediment. L. variegatus were exposed to 10 and 50 mg fullerenes/kg sediment dry mass for 28 d. These concentrations did not impact worm survival or reproduction compared to the control. Feeding activities were slightly decreased for both concentrations indicating fullerenes' disruptive effect on feeding. Depuration efficiency decreased in the high concentration only. Electron and light microscopy and extraction of the worm fecal pellets revealed fullerene agglomerates in the gut tract but not absorption into gut epithelial cells. Micrographs also indicated that 16% of the epidermal cuticle fibers of the worms were not present in the 50 mg/kg exposures, which may make worms susceptible to other contaminants. - Highlights: > Effects of fullerene-spiked sediment on black worms were investigated. > Survival, growth, reproduction, and feeding rates were measured. > Exposure did not impact worm survival or reproduction. > Feeding rates and depuration efficiency were decreased. > Worms transferred fullerenes from the sediment to the sediment surface. - Exposure to fullerene-spiked sediment decreased black worms' feeding and depuration efficiency, but fullerenes did not appear to be absorbed into the microvilli.

    Full Text Available Background: The combination of antiretroviral therapy is the corner stone of management of patients with human immune deficiency virus infection. Although antiretroviral therapy can reduce viral load to undetectable level, improve the immunity and prolong survival of patients, antiretroviral drugs are associated with many adverse effects that may be severe and affect patient adherence and quality of life. Aims : The aim of this study was to assess management strategies under taken in patient′s experienced common adverse effects of highly active antiretroviral therapy in Goba Hospital antiretroviral clinic. Patients and Methods: A cross sectional study of patient record chart of patients who had follow-up during data collection period was done followed by patient interview. Data was filled on well structured questionnaire and analyzed using SPSS for window version 16.0. Results: The common adverse effects were Rash (48.8%, Peripheral neuropathy (36.9% and Anemia (20.24%. The rate of management was 39.3%. Pyridoxine (36.8% was commonly prescribed drug for management of Peripheral neuropathy. Chlorphenarimine gel and Iron gluconate were common drugs for management of Rash and Anemia respectively. Use of traditional healers (57.7% was leading reason for non-management. Conclusion: Rate of management for common adverse effect is low. Education should be given on adverse effects for patients.

  14. Honeybees Produce Millimolar Concentrations of Non-Neuronal Acetylcholine for Breeding: Possible Adverse Effects of Neonicotinoids

    The worldwide use of neonicotinoid pesticides has caused concern on account of their involvement in the decline of bee populations, which are key pollinators in most ecosystems. Here we describe a role of non-neuronal acetylcholine (ACh) for breeding of Apis mellifera carnica and a so far unknown effect of neonicotinoids on non-target insects. Royal jelly or larval food are produced by the hypopharyngeal gland of nursing bees and contain unusually high ACh concentrations (4–8 mM). ACh is extremely well conserved in royal jelly or brood food because of the acidic pH of 4.0. This condition protects ACh from degradation thus ensuring delivery of intact ACh to larvae. Raising the pH to ≥5.5 and applying cholinesterase reduced the content of ACh substantially (by 75–90%) in larval food. When this manipulated brood was tested in artificial larval breeding experiments, the survival rate was higher with food supplemented by 100% with ACh (6 mM) than with food not supplemented with ACh. ACh release from the hypopharyngeal gland and its content in brood food declined by 80%, when honeybee colonies were exposed for 4 weeks to high concentrations of the neonicotinoids clothianidin (100 parts per billion [ppb]) or thiacloprid (8,800 ppb). Under these conditions the secretory cells of the gland were markedly damaged and brood development was severely compromised. Even field-relevant low concentrations of thiacloprid (200 ppb) or clothianidin (1 and 10 ppb) reduced ACh level in the brood food and showed initial adverse effects on brood development. Our findings indicate a hitherto unknown target of neonicotinoids to induce adverse effects on non-neuronal ACh which should be considered when re-assessing the environmental risks of these compounds. To our knowledge this is a new biological mechanism, and we suggest that, in addition to their well documented neurotoxic effects, neonicotinoids may contribute to honeybee colony losses consecutive to a reduction of the ACh content

    Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder characterized by diminished degradation of the glycosaminoglycans heparan sulfate (HS) and dermatan sulfate (DS). Patients present with a variety of symptoms, including severe skeletal disease. Current therapeutic strategies have only limited effects on bone disease. The isoflavone genistein has been studied as a potential therapy for the mucopolysaccharidoses because of its putative ability to inhibit GAG synthesis and subsequent accumulation. Cell, animal, and clinical studies, however, showed variable outcomes. To determine the effects of genistein on MPS I-related bone disease, wild-type (WT) and MPS I mice were fed a genistein-supplemented diet (corresponding to a dose of approximately 160 mg/kg/day) for 8 weeks. HS and DS levels in bone and plasma remained unchanged after genistein supplementation, while liver HS levels were decreased in genistein-fed MPS I mice as compared to untreated MPS I mice. Unexpectedly, genistein-fed mice exhibited significantly decreased body length and femur length. In addition, 60% of genistein-fed MPS I mice developed a scrotal hernia and/or scrotal hydrocele, manifestations, which were absent in WT or untreated MPS I mice. In contrast to studies in MPS III mice, our study in MPS I mice demonstraes no beneficial but even potential adverse effects of genistein supplementation. Our results urge for a cautious approach on the use of genistein, at least in patients with MPS I. PMID:25854773

    Inspection error has clearly been shown to have adverse effects upon the results desired from a quality assurance sampling plan. These effects upon performance measures have been well documented from a statistical point of view. However, little work has been presented to convince the QC manager of the unfavorable cost consequences resulting from inspection error. This paper develops a very general, yet easily used, mathematical cost model. The basic format of the well-known Guthrie-Johns model is used. However, it is modified as required to assess the effects of attributes sampling errors of the first and second kind. The economic results, under different yet realistic conditions, will no doubt be of interest to QC practitioners who face similar problems daily. Sampling inspection plans are optimized to minimize economic losses due to inspection error. Unfortunately, any error at all results in some economic loss which cannot be compensated for by sampling plan design; however, improvements over plans which neglect the presence of inspection error are possible. Implications for human performance betterment programs are apparent, as are trade-offs between sampling plan modification and inspection and training improvements economics.

  18. What is an adverse effect? A possible resolution of clinical and epidemiological perspectives on neurobehavioral toxicity

    International Nuclear Information System (INIS)

    The sizes of the effects observed in studies that rely on neurobehavioral endpoints are often small. Because the mean deficits implied are more modest in magnitude than are those that correspond to the clinical criteria used to diagnose 'disease', some observers dismiss them as inconsequential. Other observers argue that the mean deficits take on greater import when viewed as effects on a population rather than on individual members of the population. Several considerations germane to an effort to reconcile these perspectives are discussed: (1) the relative sensitivity of clinical diagnoses and continuously distributed scores on neurobehavioral tests as indices of adverse effect, (2) the syndromal nature of many diagnoses in pediatric neurology and neuropsychology and the implications of shifting nosology, (3) neurobehavioral test-score changes as surrogates or as prodromes for clinically significant deficits, (4) the distinction between individual risk and population risk, and (5) the tendency of the distribution of a risk factor in a population to move up and down as a whole. The clinical and epidemiological perspectives are complementary rather than incompatible

    Calcium-activated chloride channels(CaCCs) are the crucial regulators of transepithelial fluid secretion,smooth muscle contraction and sensory transduction. Recently, compelling evidence has indicated that TMEM 16A(ANO 1 or anoctamin-i ) is a bona fide calcium-acvtivated chloride channel. A few small molecule CaCCs regulators are available for functional and therapeutic studies. We screened 126 natural compounds from Chinese herbs. Screening was performed with an iodide influx assay in Fischer rat thyroid epithelial cells to coexpress ANOI and an iodide-sensitive fluorescent indicator(EYFP-HI48Q/I152L). lmperatorin, a coumarin compound, was identifled to inhibit ANOl-mediated chloride transport activated by multiple calcium-elevating agonists. The inhibitory effect is dose-dependent with IC50 ~14.63 μmol/L. Interestingly, imperatorin activated CFTR chloride channel with EC50 ~35.52 μmol/L. The adverse effects of imperatorin on CaCC and CFTR chloride channels will make it useful in pharmacological dissection of chloride transport in airway and intestinal epithelium. Further studies are required to evaluate the therapeutic effects of imperatorin on hypertension, asthma and certain tumors.

    Herbal products have been used for centuries among indigenous people to treat symptoms and illnesses. Recently, their use in Western countries has grown significantly, rivaling that of prescription medications. Currently, herbal products are used mainly for weight loss and bodybuilding purposes but also to improve well-being and symptoms of chronic diseases. Many people believe that because they are natural, they must be effective and safe; however, these beliefs are erroneous. Few herbal products have been studied in well-designed controlled trials of patients with liver or other diseases, despite testimony to the contrary. Moreover, current highly effective antiviral drugs make efforts to treat hepatitis C with herbal products redundant. Herbal products are no safer than conventional drugs and have caused liver injury severe enough to require transplantation or cause death. Furthermore, their efficacy, safety, and claims are not assessed by regulatory agencies, and there is uncertainty about their reported and unreported contents. We review the history of commonly used herbal products, as well as their purported efficacies and mechanisms and their adverse effects. PMID:25500423

    Lithotripter SWs rupture blood vessels in the kidney. This acute trauma, accompanied by a fall in renal function, can lead to significant long-term effects such as profound scarring of the kidney cortex and renal papillaea permanent loss of functional renal mass. SWL has been linked to new-onset hypertension in some patients, and recent studies suggest that multiple lithotripsies can actually alter a patient's stone disease leading to formation of stones (brushite) that are harder to break. Cavitation and shear appear to play a role in stone breakage and tissue damage. Progress in understanding these mechanisms, and the renal response to SWs, has led to practical strategies to improve treatment. Slowing the SW-rate, or initiating treatment at low kV/power both improve stone breakage and reduce the number of potentially tissue-damaging SWs needed to achieve comminution. The observation that SWs cause transient vasoconstriction in the kidney has led to studies in pigs showing that a pre-conditioning dose of low-energy SWs significantly reduces trauma from subsequent high-energy SWs. Thus, SWs can induce adverse effects in the kidney, but what we have learned about the mechanisms of SW action suggests strategies that could make lithotripsy safer and more effective.

    Full Text Available Gold bead implantation has been used for years as an alternative method to improve function in chronic joint disease both in humans and dogs. The aims of the present study were to describe the technique of implanting 24-karat gold beads around the hip joints of dogs with chronic hip dysplasia, and to record any side effects or complications of such treatment. A prospective placebo-controlled double-blinded clinical trial was performed. Eighty dogs were randomly allocated to treatment or placebo, with 38 in the gold implantation group and 42 in the placebo group, and followed intensely for six months. The implantation technique was simple to perform, using fluoroscopy and with the dogs under inhalation anesthesia for about 30 minutes. Adverse effects, measured as pain or discomfort, were seen for a period of up to four weeks in 15 of the dogs in the gold implantation group, compared to six dogs in the placebo group. During implantation, a technical difficulty occurred as 82% of the dogs showed leakage of blood and/or synovia from the needles. The dogs in the gold implantation group were radiographed 18 months later. Of the 30 dogs that were radiographed at both inclusion and 24 months, 80% (24 dogs showed a deterioration of the coxofemoral arthrosis, the other six had stable disease evaluated by radiography. Migration of gold beads was only observed in one dog.

    Several devices and medications have been used to address poststroke spasticity. Yet, spasticity's impact on outcomes remains controversial. Using data from a cohort of 460 ischemic stroke patients, we previously published a validated multivariable regression model for predicting 3-month modified Rankin Score (mRS) as an indicator of functional outcome. Here, we tested whether including spasticity improved model fit and estimated the effect spasticity had on the outcome. Spasticity was defined by a positive response to the question "Did you have spasticity following your stroke?" on direct interview at 3 months from stroke onset. Patients who had expired by 90 days (n = 30) or did not have spasticity data available (n = 102) were excluded. Spasticity affected the 3-month functional status (β = 0.420, 95 CI = 0.194 to 0.645) after accounting for age, diabetes, leukoaraiosis, and retrospective NIHSS. Using spasticity as a covariable, the model's R (2) changed from 0.599 to 0.622. In our model, the presence of spasticity in the cohort was associated with a worsened 3-month mRS by an average of 0.4 after adjusting for known covariables. This significant adverse effect on functional outcomes adds predictive value beyond previously established factors. PMID:25147752

In our model, the presence of spasticity in the cohort was associated with a worsened 3-month mRS by an average of 0.4 after adjusting for known covariables. This significant adverse effect on functional outcomes adds predictive value beyond previously established factors.

    Gold bead implantation has been used for years as an alternative method to improve function in chronic joint disease both in humans and dogs. The aims of the present study were to describe the technique of implanting 24-karat gold beads around the hip joints of dogs with chronic hip dysplasia, and to record any side effects or complications of such treatment. A prospective placebo-controlled double-blinded clinical trial was performed. Eighty dogs were randomly allocated to treatment or placebo, with 38 in the gold implantation group and 42 in the placebo group, and followed intensely for six months. The implantation technique was simple to perform, using fluoroscopy and with the dogs under inhalation anesthesia for about 30 minutes. Adverse effects, measured as pain or discomfort, were seen for a period of up to four weeks in 15 of the dogs in the gold implantation group, compared to six dogs in the placebo group. During implantation, a technical difficulty occurred as 82% of the dogs showed leakage of blood and/or synovia from the needles. The dogs in the gold implantation group were radiographed 18 months later. Of the 30 dogs that were radiographed at both inclusion and 24 months, 80% (24 dogs) showed a deterioration of the coxofemoral arthrosis, the other six had stable disease evaluated by radiography. Migration of gold beads was only observed in one dog. PMID:26487031

    INTRODUCTION: Current space suits have limited movement due to gas pressurization during exposure to the vacuum of space. Alternatively, if pressure is applied by an elastic garment vs. pneumatic garment to produce mechanical counter pressure (MCP), several advantages are possible. In this study, we investigate local microcirculatory and other effects produced with and without a prototype MCP glove and sleeve during exposure to varying levels of vacuum. METHODS: The entire arms of eight male volunteers were studied at normal ambient pressure and during 5 min exposures to -50, -100, and -150 mm Hg with and without the MCP glove and sleeve. Pressure distribution, skin microvascular flow, and temperature were measured. RESULTS: The MCP glove and sleeve generated over 200 mm Hg on the middle finger, dorsum of the hand, and the wrist. However, pressure was significantly lower on the forearm and the upper arm. Without the glove and sleeve, only two of eight subjects tolerated -100 mm Hg. Also, no subject tolerated -150 mm Hg. However, subjects tolerated all vacuum pressures wearing the glove and sleeve. Skin microvascular flow and temperature remained within control values with the glove and sleeve at a chamber pressure of -150 mm Hg. DISCUSSION: The MCP glove and sleeve counteracts adverse effects of vacuum exposures due to lower pressure differentials. Pressure levels over the hand and wrist are similar to those of the current U.S. space suit glove and sleeve, but additional development is required to increase MCP over the forearm and upper arm.

    Seven-day batch equilibrium experiments were conducted to measure the efficacy of four phosphate amendments (trisodium trimetaphosphate [TP3], dodecasodium phytate [Na-IP6], precipitated calcium phytate [Ca-IP6], and hydroxyapatite [HA]) for immobilizing Ni and U in organic-rich sediment. Using the eight-step modified Miller's sequential extraction procedure and the USEPA's Toxicity Characteristic Leaching Procedure, the effect of these amendments on the distribution of Ni and U was assessed. Relative to unamended controls, equilibrium aqueous-phase U concentrations were lower following HA and Ca-IP6 additions but higher following TP3 and Na-IP6 amendments, whereas aqueous Ni concentrations were not decreased only in the Na-IP6 amended treatment relative to the control. The poor rates of contaminant immobilization following TP3 and Na-IP6 amendments correlate with the dispersion of organic matter and organo-mineral colloids, which probably contain sorbed U and Ni. While all amendments shifted the U distribution toward more recalcitrant soil fractions, Ni was redistributed to more labile soil fractions. This study cautions that the addition of orthophosphates and organophosphates as contaminant immobilizing amendments may in fact have adverse effects, especially in high-organic soils. Particular attention is warranted at sites with mixed contaminants with varying geochemical behaviors. PMID:21712583

  8. Analysis of heavy-ion irradiation induced adverse effect on normal tissue in murine model

    International Nuclear Information System (INIS)

    The purpose of this study was to clarify the molecular mechanism of C-ion radiation induced late injury of lung and urinary bladder in normal tissue, using murine model. Exposures were conducted using horizontal carbon-12 beams with 290 MeV/u at a dose rate of approximately 3 Gy/min within the 6-cm spread-out Bragg peak (SOBP). To evaluate the effects of C-ion irradiation on lungs, pathological changes after thoracic irradiation were analyzed. To evaluate the adverse effects on the bladder, pathological evaluation were performed. The gene expression analysis were performed using total RNA derived from irradiated tissues on 6 hour after irradiation to elucidate the molecular response to irradiation. Survival assay revealed the subacute phase death by hemorrhagic pneumonitis in C3H/He and the late phase death by pulmonary fibrosis in C57BL/6J after C-ion irradiation. Microarray analysis presented the genes with strain variance after C-ion irradiation. Immunohistochemical staining of LAMP family proteins, which relates bladder contraction, in the irradiated urinary bladder were different between strains. (author)

    Although endothelin receptor antagonists (ERAs) including bosentan and ambrisentan are essential tools for the treatment of pulmonary arterial hypertension (PAH), each agent has a specific adverse effect with non-negligible frequency, ie, liver dysfunction for bosentan and peripheral edema for ambrisentan. These adverse effects often hinder the titration of the doses of ERAs up to the therapeutic levels. Portopulmonary hypertension, which is complicated with liver cirrhosis and successive portal hypertension, is one of the PAHs refractory to general anti-PAH agents because of the underlying progressed liver dysfunction and poor systemic condition. We here present a patient with portopulmonary hypertension, which was treated safely by combination therapy that included low-dose bosentan and ambrisentan, minimizing the adverse effects of each ERA. Combination therapy including different types of ERAs at each optimal dose may become a breakthrough to overcome portopulmonary hypertension in the future. PMID:26084462

    Steroids are important physiological orchestrators of endocrine as well as peripheral and central nervous system functions. One of the key processes for regulation of these molecules lies in their enzymatic processing by a family of 5α-reductase (5α-Rs) isozymes. By catalyzing a key rate-limiting step in steroidogenesis, this family of enzymes exerts a crucial role not only in the physiological control but also in pathological events. Indeed, both 5α-R inhibition and supplementation of 5α-reduced metabolites are currently used or have been proposed as therapeutic strategies for a wide array of pathological conditions. In particular, the potent 5α-R inhibitors finasteride and dutasteride are used in the treatments of benign prostatic hyperplasia (BPH), as well as in male pattern hair loss (MPHL) known as androgenetic alopecia (AGA). Recent preclinical and clinical findings indicate that 5α-R inhibitors evoke not only beneficial, but also adverse effects. Future studies should investigate the biochemical and physiological mechanisms that underlie the persistence of the adverse sexual side effects to determine why a subset of patients is afflicted with such persistence or irreversible adverse effects. Also a better focus of clinical research is urgently needed to better define those subjects who are likely to be adversely affected by such agents. Furthermore, research on the non-sexual adverse effects such as diabetes, psychosis, depression, and cognitive function are needed to better understand the broad spectrum of the effects these drugs may elicit during their use in treatment of AGA or BPH. In this review, we will summarize the state of art on this topic, overview the key unresolved questions that have emerged on the pharmacological targeting of these enzymes and their products, and highlight the need for further studies to ascertain the severity and duration of the adverse effects of 5α-R inhibitors, as well as their biological underpinnings.

    Full Text Available The adverse effect of cypermethrin on the liver and kidney of weanling female rats and the protective effect of ethanolic extract of grape pomace were investigated in the present study. Weanling female rats were given cypermethrin oral at a dose of 25 mg kg−1 body weight for 28 consecutive days. An additional two Cyp-trated groups received extract at a dose of 100 and 200 mg kg−1 body weight, respectively, throughout the experimental duration. Three groups more served as extract and control groups. Administration of Cyp resulted in a significant increase in serum marker enzymes, for example, aminotransferases (AST and ALT, alkaline phosphatase (ALP, and gamma-glutamyl transferase (GGT, and increases the level of urea nitrogen and creatinine. In contrast, Cyp caused significant decrease in levels of total protein and albumin and caused histopathological alterations in liver and kidneys of female rats. Coadministration of the extract to Cyp-treated female rats restored most of these biochemical parameters to within normal levels especially at high dose of extract. However, extract administration to Cyp-treated rats resulted in overall improvement in liver and kidney damage. This study demonstrated the adverse biohistological effects of Cyp on the liver and kidney of weanling female rats. The grape pomace extract administration prevented the toxic effect of Cyp on the above serum parameters. The present study concludes that grape pomace extract has significant antioxidant and hepatorenal protective activity.

  14. Evaluating legacy contaminants and emerging chemicals in marine environments using adverse outcome pathways and biological effects-directed analysis

    International Nuclear Information System (INIS)

    Natural and synthetic chemicals are essential to our daily lives, food supplies, health care, industries and safe sanitation. At the same time protecting marine ecosystems and seafood resources from the adverse effects of chemical contaminants remains an important issue. Since the 1970s, monitoring of persistent, bioaccumulative and toxic (PBT) chemicals using analytical chemistry has provided important spatial and temporal trend data in three important contexts; relating to human health protection from seafood contamination, addressing threats to marine top predators and finally providing essential evidence to better protect the biodiversity of commercial and non-commercial marine species. A number of regional conventions have led to controls on certain PBT chemicals over several years (termed ‘legacy contaminants’; e.g. cadmium, lindane, polycyclic aromatic hydrocarbons [PAHs] and polychlorinated biphenyls [PCBs]). Analytical chemistry plays a key role in evaluating to what extent such regulatory steps have been effective in leading to reduced emissions of these legacy contaminants into marine environments. In parallel, the application of biomarkers (e.g. DNA adducts, CYP1A-EROD, vitellogenin) and bioassays integrated with analytical chemistry has strengthened the evidence base to support an ecosystem approach to manage marine pollution problems. In recent years, however, the increased sensitivity of analytical chemistry, toxicity alerts and wider environmental awareness has led to a focus on emerging chemical contaminants (defined as chemicals that have been detected in the environment, but which are currently not included in regulatory monitoring programmes and whose fate and biological impacts are poorly understood). It is also known that natural chemicals (e.g. algal biotoxins) may also pose a threat to marine species and seafood quality. Hence complex mixtures of legacy contaminants, emerging chemicals and natural biotoxins in marine ecosystems represent

    2014-02-01

    The health benefits of exercise are well known. Many of the most accessible forms of exercise, such as walking, cycling, and running often occur outdoors. This means that exercising outdoors may increase exposure to urban air pollution. Regular exercise plays a key role in improving some of the physiologic mechanisms and health outcomes that air pollution exposure may exacerbate. This problem presents an interesting challenge of balancing the beneficial effects of exercise along with the detrimental effects of air pollution upon health. This article summarizes the pulmonary, cardiovascular, cognitive, and systemic health effects of exposure to particulate matter, ozone, and carbon monoxide during exercise. It also summarizes how air pollution exposure affects maximal oxygen consumption and exercise performance. This article highlights ways in which exercisers could mitigate the adverse health effects of air pollution exposure during exercise and draws attention to the potential importance of land use planning in selecting exercise facilities.

    Full Text Available Salinity is a major limiting factor for crop production in coastal areas of Bangladesh. Organic amendments could contribute to the improvement of crop production in coastal areas. Two maize cultivars (BARI Hybrid Maize-5 and Hybrid Maize Pacific-987 were grown in pots to investigate the mitigating adverse effects of salt stress in maize by organic amendments. Two doses of farmyard manure (FYM and poultry manure (PM were mixed with soils before seed sowing. Plants were subjected to salinity (0-50 mM NaCl at vegetative stage. Salt stress caused a significant reduction in growth and yield of both maize cultivars. Higher NaCl (50 mM stress caused a drastic decrease in growth and yield of both maize cultivars. Salinity also decreased reproductive growth, chlorophyll contents and K+/Na+ ratio in both maize cultivars. Organic amendments with FYM and PM improved salt tolerances of maize that were associated with increased yield components, chlorophyll content and K+/Na+ ratio. Hybrid Maize Pacific-987 grown in low salinity with FYM or PM amendments produced higher yield than control condition. On the contrary, BARI Hybrid Maize-5 conferred tolerance to high salinity, when soils were amended with FYM or PM. Furthermore, organic amendments improved electrical conductivity, exchangeable Na and organic matter status under salinity condition. The present study suggests that organic amendments with FYM or PM confer tolerance to salinity in maize by increasing chlorophyll content and K+/Na+ ratio.

    Calcium dyshomeostasis is an important pathology of memory impairment. However, the mechanism of how calcium dyshomeostasis impairs neurons has remained elusive. The aim of the present study was to reveal the influence of calcium dyshomeostasis on the expression of calcium memory‑associated proteins and the ability of raloxifene to neutralize the adverse effects of glutamate on cultured neurons by regulation of calcium oscillations. After neurons were treated with various concentrations of glutamate alone or with raloxifene, the expression of calcium memory‑associated proteins and the influence on calcium dyshomeostasis was assessed. The results indicated that glutamate regulated calcium oscillation waves and expression of calcium memory‑associated protein in a concentration‑dependent manner. Raloxifene increased the expression of these proteins as well as neuronal survival. It is therefore concluded that glutamate regulated calcium oscillations in a dose‑dependent manner, while raloxifene protected neurons from destruction through glutamate exposure and at the same time neutralized the decrease in expression of the memory‑associated proteins.

    Full Text Available During postnatal development, adverse early life experiences can affect the formation of neuronal circuits and exert long-lasting influences on neural function. Many studies have shown that daily repeated MS, an animal model of early life stress, can modulate the hypothalamic-pituitary-adrenal axis (HPA axis and can affect subsequent brain function and emotional behavior during adulthood. However, the molecular basis of the long-lasting effects of early life stress on brain function has not been completely elucidated. In this review, we introduce various cases of MS in rodents and illustrate the alterations in HPA axis activity by focusing on corticosterone (CORT, an end product of the HPA axis in rodents. We then present a characterization of the brain regions affected by various patterns of MS, including repeated MS and single time MS at various stages before weaning, by investigating c-Fos expression, a biological marker of neuronal activity. These CORT and c-Fos studies suggest that repeated early life stress may affect neuronal function in region- and temporal-specific manners, indicating a critical period for habituation to early life stress. Next, we discuss how early life stress can impact behavior, namely by inducing depression, anxiety or eating disorders. Furthermore, alterations in gene expression in adult mice exposed to MS, especially epigenetic changes of DNA methylation, are discussed.

  4. Avoiding adverse employment effects from electricity taxation in Norway: What does it cost?

    International Nuclear Information System (INIS)

    Welfare analyses of energy taxes typically show that systems with uniform rates perform better than differentiated systems. However, most western countries include some exemptions for their energy-intensive export industries and thereby avoid this potential welfare gain. find that uniform taxation of carbon emissions in combination with a wage subsidy preserves jobs in these industries at a lower welfare cost compared with a differentiated system. The wage subsidy scheme generates a substantial welfare gain per job saved. This study, however, finds that welfare costs are substantial when less accurate policy measures, represented by production-dependent subsidies, protect jobs in Norwegian electricity-intensive industries. The welfare cost per job preserved by this subsidy scheme amounts to approximately 60% of the wage cost per job, suggesting that these jobs are expensive to preserve. A uniform electricity tax combined with production-dependent subsidies preserves jobs at a lower welfare cost compared with the current differentiated electricity tax system. - Highlights: → Avoiding adverse employment effects from electricity taxation is costly in Norway. → Uniform Norwegian electricity tax with job-preserving subsidies improves welfare. → The welfare cost of Norwegian job-saving subsidies amounts to 60% of the wage.

  5. Biomarkers in natural fish populations indicate adverse biological effects of offshore oil production.

    Directory of Open Access Journals (Sweden)

    Lennart Balk

    Full Text Available BACKGROUND: Despite the growing awareness of the necessity of a sustainable development, the global economy continues to depend largely on the consumption of non-renewable energy resources. One such energy resource is fossil oil extracted from the seabed at offshore oil platforms. This type of oil production causes continuous environmental pollution from drilling waste, discharge of large amounts of produced water, and accidental spills. METHODS AND PRINCIPAL FINDINGS: Samples from natural populations of haddock (Melanogrammus aeglefinus and Atlantic cod (Gadus morhua in two North Sea areas with extensive oil production were investigated. Exposure to and uptake of polycyclic aromatic hydrocarbons (PAHs were demonstrated, and biomarker analyses revealed adverse biological effects, including induction of biotransformation enzymes, oxidative stress, altered fatty acid composition, and genotoxicity. Genotoxicity was reflected by a hepatic DNA adduct pattern typical for exposure to a mixture of PAHs. Control material was collected from a North Sea area without oil production and from remote Icelandic waters. The difference between the two control areas indicates significant background pollution in the North Sea. CONCLUSION: It is most remarkable to obtain biomarker responses in natural fish populations in the open sea that are similar to the biomarker responses in fish from highly polluted areas close to a point source. Risk assessment of various threats to the marine fish populations in the North Sea, such as overfishing, global warming, and eutrophication, should also take into account the ecologically relevant impact of offshore oil production.

    2012-02-01

    Full Text Available Abstract Background The optimum protocol for expander volume adjustment with respect to the timing and application of radiotherapy remains controversial. Methods Eighteen New Zealand rabbits were divided into three groups. Metallic port integrated anatomic breast expanders of 250 cc were implanted on the back of each animal and controlled expansion was performed. Group I underwent radiotherapy with full expanders while in Group II, expanders were partially deflated immediately prior to radiotherapy. Control group did not receive radiotherapy. The changes in blood flow at different volume adjustments were investigated in Group II by laser Doppler flowmetry. Variations in the histopathologic properties of the irradiated tissues including the skin, capsule and the pocket floor, were compared in the biopsy specimens taken from different locations in each group. Results A significant increase in skin blood flow was detected in Group II with partial expander deflation. Overall, histopathologic exam revealed aggravated findings of chronic radiodermatitis (epidermal atrophy, dermal inflammation and fibrosis, neovascularisation and vascular changes as well as increased capsule thickness especially around the lower expander pole, in Group II. Conclusions Expander deflation immediately prior to radiotherapy, may augment the adverse effects, especially in the lower expander pole, possibly via enhanced radiosensitization due to a relative increase in the blood flow and tissue oxygenation.

    In this study, we evaluated whether supplementation with antioxidant vitamins can reduce the adverse effects of irradiation on the salivary glands in the rat. Four groups of adult Sprague-Dawley rats were given a basic diet providing 0.6 mg {alpha}-tocopherol and no {beta}-carotene per day. In two groups the basic diet was supplemented with 3.4 mg {alpha}-tocopherol and 6 mg {beta}-carotene per day from 14 days before irradiation until 12 days after complete irradiation. One group of rats given basic diet and one group given supplemented diet were irradiated with 7 Gy daily for five consecutive days. Isoproterenol and pilocarpine-stimulated whole saliva was collected from all rats 2, 4 and 26 weeks after irradiation. Vitamin-supplemented irradiated rats had higher secretion rates on all three occasions compared with those of irradiated rats given basic diet. The changes in saliva composition seen in irradiated rats were less accentuated in vitamin-supplemented, irradiated rats. The proportions of acinar cells were significantly decreased both in parotid and submandibular glands 26 weeks after irradiation. Supplementation with {alpha}-tocopherol and {beta}-carotene did not alter the morphology of the glands. (author).

  9. Methyl donor supplementation blocks the adverse effects of maternal high fat diet on offspring physiology.

    Directory of Open Access Journals (Sweden)

    Jesselea Carlin

    Full Text Available Maternal consumption of a high fat diet during pregnancy increases the offspring risk for obesity. Using a mouse model, we have previously shown that maternal consumption of a high fat (60% diet leads to global and gene specific decreases in DNA methylation in the brain of the offspring. The present experiments were designed to attempt to reverse this DNA hypomethylation through supplementation of the maternal diet with methyl donors, and to determine whether methyl donor supplementation could block or attenuate phenotypes associated with maternal consumption of a HF diet. Metabolic and behavioral (fat preference outcomes were assessed in male and female adult offspring. Expression of the mu-opioid receptor and dopamine transporter mRNA, as well as global DNA methylation were measured in the brain. Supplementation of the maternal diet with methyl donors attenuated the development of some of the adverse effects seen in offspring from dams fed a high fat diet; including weight gain, increased fat preference (males, changes in CNS gene expression and global hypomethylation in the prefrontal cortex. Notable sex differences were observed. These findings identify the importance of balanced methylation status during pregnancy, particularly in the context of a maternal high fat diet, for optimal offspring outcome.

    This study investigates the mechanisms accounting for the adverse cholinergic effects of the antitumour drug irinotecan. The activity of irinotecan and its active metabolite, 7-ethyl-10-hydroxy-camptothecin (SN-38), was assayed in models suitable for pharmacological studies on cholinergic system. Irinotecan moderately inhibited human or electric eel acetylcholinesterase activity, SN-38 had no effect, whereas physostigmine blocked both the enzymes with high potency and efficacy. Irinotecan and SN-38 did not affect spontaneous or electrically-induced contractile activity of human colonic muscle. Acetylcholine and dimethylphenylpiperazinium (DMPP) caused phasic contractions or relaxations, respectively. Physostigmine enhanced the motor responses elicited by electrical stimulation. Although irinotecan and SN-38 did not modify the basal contractile activity of guinea-pig ileum longitudinal muscle strips, irinotecan 100 μM moderately enhanced cholinergic twitch contractions. Acetylcholine or DMPP caused phasic contractions, whereas physostigmine enhanced the twitch responses. Electrically-induced [3H]-acetylcholine release was reduced by irinotecan (100 μM) or physostigmine (0.1 μM). Intravenous irinotecan stimulated gastric acid secretion in rats, but no effects were obtained with SN-38, physostigmine or i.c.v. irinotecan. Hypersecretion induced by irinotecan was partly prevented by ondansetron, and unaffected by capsazepine. In the presence of atropine, vagotomy and systemic or vagal ablation of capsaicin-sensitive afferent fibres, irinotecan did not stimulate gastric secretion. The present results indicate that irinotecan and SN-38 do not act as specific acetylcholinesterase blockers or acetylcholine receptor agonists. It is rather suggested that irinotecan promotes a parasympathetic discharge to peripheral organs, mediated by capsaicin-sensitive vagal afferent fibres, and that serotonin 5-HT3 receptors are implicated in the genesis of vago-vagal reflex

    Halle, Rob J.

    2016-01-01

    ABSTRACT Background Dry needling is an evidence-based treatment technique that is accepted and used by physical therapists in the United States. This treatment approach focuses on releasing or inactivating muscular trigger points to decrease pain, reduce muscle tension, and assist patients with an accelerated return to active rehabilitation. Issue While commonly used, the technique has some patient risk and value of the treatment should be based on benefit compared to the potential risk. Adverse effects (AEs) with dry needling can be mild or severe, with overall incidence rates varying from zero to rates of approximately 10 percent. While mild AEs are the rule, any procedure that involves a needle insertion has the potential for an AE, with select regions and the underlying anatomy increasing the risk. Known significant AEs from small diameter needle insertion include pneumothorax, cardiac tamponade, hematoma, infection, central nervous system injury, and other complications. Purpose/Objective Underlying anatomy across individuals has variability, requiring an in-depth knowledge of anatomy prior to any needle placement. This commentary is an overview of pertinent anatomy in the region of the thorax, with a ‘part two’ that addresses the abdomen, pelvis, back, vasovagal response, informed consent and other pertinent issues. The purpose of the commentary is to minimize the risk of a dry needling AE. Conclusions/Implications Dry needling is an effective adjunct treatment procedure that is within the recognized scope of physical therapy practice. Physical therapy education and training provides practitioners with the anatomy, basic sciences, and clinical foundation to use this intervention safely and effectively. A safe and evidenced-based implementation of the procedure is based on a thorough understanding of the underlying anatomy and the potential risks, with risks coordinated with patients via informed consent.

    Full Text Available Electronic healthcare records (EHRs are a rich source of information, with huge potential for secondary research use. The aim of this study was to develop an application to identify instances of Adverse Drug Events (ADEs from free text psychiatric EHRs.We used the GATE Natural Language Processing (NLP software to mine instances of ADEs from free text content within the Clinical Record Interactive Search (CRIS system, a de-identified psychiatric case register developed at the South London and Maudsley NHS Foundation Trust, UK. The tool was built around a set of four movement disorders (extrapyramidal side effects [EPSEs] related to antipsychotic therapy and rules were then generalised such that the tool could be applied to additional ADEs. We report the frequencies of recorded EPSEs in patients diagnosed with a Severe Mental Illness (SMI and then report performance in identifying eight other unrelated ADEs.The tool identified EPSEs with >0.85 precision and >0.86 recall during testing. Akathisia was found to be the most prevalent EPSE overall and occurred in the Asian ethnic group with a frequency of 8.13%. The tool performed well when applied to most of the non-EPSEs but least well when applied to rare conditions such as myocarditis, a condition that appears frequently in the text as a side effect warning to patients.The developed tool allows us to accurately identify instances of a potential ADE from psychiatric EHRs. As such, we were able to study the prevalence of ADEs within subgroups of patients stratified by SMI diagnosis, gender, age and ethnicity. In addition we demonstrated the generalisability of the application to other ADE types by producing a high precision rate on a non-EPSE related set of ADE containing documents.The application can be found at http://git.brc.iop.kcl.ac.uk/rmallah/dystoniaml.

  17. Adverse effects of endocrine disruptors on the foetal testis development: focus on the phthalates.

    Full Text Available There are great concerns about the increasing incidence of abnormalities in male reproductive function. Human sperm counts have markedly dropped and the rate of testicular cancer has clearly augmented over the past four decades. Moreover, the prevalence rates of cryptorchidism and hypospadias are also probably increasing. It has been hypothesized that all these adverse trends in male reproduction result from abnormalities in the development of the testis during foetal and neonatal life. Furthermore, many recent epidemiological, clinical and experimental data suggest that these male reproductive disorders could be due to the effects of xenobiotics termed endocrine disruptors, which are becoming more and more concentrated and prevalent in our environment. Among these endocrine disruptors, we chose to focus this review on the phthalates for different reasons: 1 they are widespread in the environment; 2 their concentrations in many human biological fluids have been measured; 3 the experimental data using rodent models suggesting a reprotoxicity are numerous and are the most convincing; 4 their deleterious effects on the in vivo and in vitro development and function of the rat foetal testis have been largely studied; 5 some epidemiological data in humans suggest a reprotoxic effect at environmental concentrations at least during neonatal life. However, the direct effects of phthalates on human foetal testis have never been explored. Thus, as we did for the rat in the 1990s, we recently developed and validated an organ culture system which allows maintenance of the development of the different cell types of human foetal testis. In this system, addition of 10-4 M MEHP (mono-2-ethylhexyl phthalate, the most produced phthalate, had no effect on basal or LH-stimulated production of testosterone, but it reduced the number of germ cells by increasing their apoptosis, without modification of their proliferation. This is the first experimental demonstration

    Global health research typically relies on the translation of knowledge (from health professionals to the community) and the dissemination of knowledge (from research results to the wider public). However, Greenhalgh and Wieringa [2011. Is it time to drop the 'knowledge translation' metaphor? A critical literature review. Journal of the Royal Society of Medicine, 104(12), 501-509. doi: 10.1258/jrsm.2011.110285 ] suggest 'that while "translation" is a widely used metaphor in medicine, it constrains how we conceptualize and study the link between knowledge and practice' (p. 501). Often the knowledge garnered from such research projects comes from health professionals rather than reflecting the lived experiences of people and communities. Likewise, there has been a gap in 'translating' and 'disseminating' the results of participatory action research projects to policymakers and medical practitioners. This paper will look at how using participatory visual methodologies in global health research with children and youth facing global adversity incorporates the multiple functions of their lived realities so that research becomes a means of intervention. Drawing from a literature review of participatory visual methods as media, content and processes of global health research, this paper raises practical, theoretical, and ethical questions that arise from research as intervention. The paper concludes by exploring what lessons emerge when participatory visual methodologies are integrated into global health research with children and youth facing global adversity. PMID:27043374

    Bioaccumulation of trivalent (CrIII) and hexavalent chromium (CrVI), and its adverse effects were studied in two rotifer species: Brachionus calyciflorus (two different strains), and Lecane quadridentata. Median Lethal Concentration (LC50) at 24 h of both species showed that CrVI is highly toxic: LC50 ranges from 4.7 × 10(-5) to 4 × 10(-6) mg L(-1)), compared with CrIII: LC50 ranges from 0.64 to 1.279 mg L(-1). Using the LC50 as an exposure concentration, and using atomic absorption, the bioconcentration factor (BCF) was obtained and BCFs of rotifers exposed to CrIII are four orders of magnitude lower than BCFs of rotifers exposed to CrVI. The effect of Cr on the elemental composition of the two species of rotifers in their structures by X-ray microanalysis by energy dispersion showed that Cr is found in intoxicated rotifers, but not in control rotifers. The basal immunoreactivity to metallothioneins is greater in B. calyciflorus than L. quadridentata. The immunoreactivity to metallothioneins decreases in B. calyciflorus when is exposed to CrIII, in contrast in L. quadridentata the immunoreactivity to metallothioneins increase when is exposed to CrIII, and the immunoreactivity to CrVI in L. quadridentata decrease. A mechanism is proposed in which the harder lorica of L. quadridentata acts as a barrier and accumulator of CrVI, and allows for attenuating responses like metallothionein production in L. quadridentata. Instead, in B. calyciflorus the lack of a harder lorica allows for deeper penetration of CrVI, and no time to produce attenuating measures. PMID:27258901

    The extensive flooding in the aftermath of Hurricanes Katrina and Rita created conditions ideal for indoor mold growth, raising concerns about the possible adverse health effects associated with indoor mold exposure. Studies evaluating the levels of indoor and outdoor molds in the months following the hurricanes found high levels of mold growth. Homes with greater flood damage, especially those with >3 feet of indoor flooding, demonstrated higher levels of mold growth compared with homes with little or no flooding. Water intrusion due to roof damage was also associated with mold growth. However, no increase in the occurrence of adverse health outcomes has been observed in published reports to date. This article considers reasons why studies of mold exposure after the hurricane do not show a greater health impact. PMID:20070193

  3. Adverse effects to iodinated contrast media in interleukin-2 treated patients

    International Nuclear Information System (INIS)

    Interleukin-2 (IL-2) is a potent modulator of immune response that provokes tumor regression in cancer patients. IL-2 may induce sensitization to radiological iodinated contrast media (ICM) and this phenomenon has been rarely reported in literature. We report the increased incidence of adverse reactions to ICM patients treated with systemic IL-2, discuss the possible mechanisms of action, and propose patient management strategies. Retrospective study was conducted in 168 patients treated with subcutaneous IL-2 and 544 patients who did not.CT scans were performed with intravenous administration of 80-160 ml of nonionic ICM with a power injector. The incidence of adverse reactions to ICM among our patients was 7.14%. It differs significantly (p<0.001) from that in the control group ((1.28%). Thus, patients treated with IL-2 have a relative risk of 5,6 times (CI 95%; 2.2-13.9). The adverse reactions in IL-2 patients were mild and resolved promptly without treatment in 11 patients. In one patient hypotension required intravenous forced hydration. Patients on IL-2 treatment may be at risk of experiencing contrast induced adverse reactions. Potent of the immune system by IL-2 may increase the potential risk for hypersensitivity or other adverse reactions to ICM. Knowledge of this fact may be valuable in clinical decision making and patient follow-up strategies. (Author) 18 refs

    Objective This study sought to clarify the relationship between childhood trauma and adversity with later alcohol consumption and the moderating effects of adult psychosocial stress. Method Seventy-seven recently abstinent alcohol-dependent men attending residential treatment programs were assessed. Childhood trauma/adversity was assessed with the Childhood Trauma Questionnaire (CTQ), drinks per drinking day (DDD) with the TimeLine Follow Back, and chronic psychosocial stress with the UCLA Stress Interview. Drinking and stress were retrospectively assessed for six months prior to the present treatment episode. Direct associations between childhood trauma/adversity and alcohol consumption and the moderating effects of recent psychosocial stress were assessed. All measures were considered as continuous variables. Results Pretreatment drinking severity (DDD) was associated with CTQ Total score (p = .009) and the Emotional Abuse (p < .001) and Physical Abuse (p < .01) subscales. UCLA Total Stress significantly moderated the effects of CTQ Total score on drinking severity (p = .04). Whereas higher CTQ scores were significantly associated with a greater amount of pretreatment drinking in participants with high UCLA stress scores (p = .01), CTQ scores were not associated with the amount of drinking in those with low UCLA stress scores (p = .63). Conclusions Childhood trauma predicts drinking severity in alcohol-dependent men and this effect is stronger in participants with ongoing stress in adult life. These findings suggest that early childhood trauma/adversity may sensitize stress-response systems. PMID:24635549

    Throughout the world, herbal medicines are consumed by most of the patients without considering their adverse effects. Many herbal medicines/plant extracts have been reported to interact with the natural blood clotting system. In continuation to this effort, thirty medicinal plant extracts were allowed to interact with citrated human blood and the clotting time was measured after re-calcification in vitro using Lee and White method. The aq. leaf ext. of Syzygium cumini and Camellia sinensis significantly prolonged the clotting time. In response to the prothrombin time and activated partial thromboplastin time tests, the ext. of C. sinensis showed normal APTT and marginally prolonged the PT to 16.7 s (control-15.2 s) while S. cumini showed normal PT but significantly prolonged the APTT to 66.9 s (control-20.7 s). This suggests that, C. sinensis acts on the extrinsic pathway while S. cumini on the intrinsic pathway. There are some common herbal formulations that are frequently used by the patients which contain above plant materials, like, Syzygium cumin in anti-diabetic formulations, while the ext. of C. sinensis is consumed frequently as beverage in many part of the world. Hence, patients having known bleeding tendency or haemophilia disease should take into account the interaction potential of these plants with the natural blood clotting system while taking herbal formulations containing above plants; specially, the patients suffering from intrinsic pathway factor deficiency should keep a limit on the consumption of S. cumini while extrinsic pathway factor deficiency patients should limit C. sinensis. Also, the medical practitioners should consider the patient's food consumption history before doing any major surgical procedures. PMID:26340850

    Full Text Available PURPOSE: To determine whether pre-treatment growth rate of vestibular schwannomas (VS predict response to radiosurgery. METHODS: A retrospective review of a prospectively maintained database of all VS patients treated with 12Gy prescription dose between September 2005 and June 2011 at our institution using the Leksell Model 4C Gamma Knife Unit was conducted. Patients who had a minimum of 12-months clinical and radiological assessment before and after radiosurgery were included in this study. Tumor growth rates were calculated using specific growth rate (SGR. Tumor volumes were measured on FIESTA-MRI scans using ITK-SNAP v2.2. RESULTS: Following radiosurgery, twenty-seven (42.9% patients showed a significant decrease in volume after one year, twenty-nine (46.0% stabilized, and seven (11.1% continued to grow. There was no correlation between VS pre-treatment SGRs with post-treatment SGRs (p = 0.34, and incidence of adverse radiation effects (ARE. The reduction in tumors' SGRs after radiosurgery was proportional to pre-treatment SGRs, although this correlation was not statistically significant (p = 0.19. Analysis of risk factors revealed a positive correlation between post-treatment SGRs and incidence of non-auditory complications, most of which were attributed to ARE (p = 0.047. CONCLUSION: Pre-treatment growth rate of VS does not predict tumor response to radiosurgery or incidence of ARE. VS with higher SGRs post-radiosurgery are more likely to experience ARE.

    A dysregulation of the hypothalamus-pituitary-adrenocortical (HPA) axis and the experience of early-life adversity are both well-established risk factors for the development of affective disorders, such as major depression. However, little is known about the interaction of these two factors in shaping endophenotypes of the disease. Here, we studied the gene-environment interaction of a genetic predisposition for HPA axis dysregulation with early-life stress (ELS), assessing the short-, as well as the long-lasting consequences on emotional behavior, neuroendocrine functions and gene expression profiles. Three mouse lines, selectively bred for either high (HR), intermediate (IR), or low (LR) HPA axis reactivity, were exposed to one week of ELS using the limited nesting and bedding material paradigm. Measurements collected during or shortly after the ELS period showed that, regardless of genetic background, ELS exposure led to impaired weight gain and altered the animals' coping behavior under stressful conditions. However, only HR mice additionally showed significant changes in neuroendocrine stress responsiveness at a young age. Accordingly, adult HR mice also showed lasting consequences of ELS, including hyperactive stress-coping, HPA axis hyperreactivity, and gene expression changes in the Crh system, as well as downregulation of Fkbp5 in relevant brain regions. We suggest that the genetic predisposition for high stress reactivity interacts with ELS exposure by disturbing the suppression of corticosterone release during a critical period of brain development, thus exerting lasting programming effects on the HPA axis, presumably via epigenetic mechanisms. In concert, these changes lead to the emergence of important endophenotypes associated with affective disorders. PMID:27179233

The palates were immersed in one of the following solutions: total suspended particles (0.1 mg/mL, particulate matter 2.5 µm 0.1 mg/mL (PM0.1 or 3.0 mg/mL (PM3.0 and amphibian Ringer’s solution (control. Particle chemical compositions were determined by X-ray fluorescence and gas chromatography/mass spectrometry.RESULTS:Exposure to total suspended particles and PM3.0 decreased mucociliary transport. Ciliary beating frequency was diminished by total suspended particles at all times during exposure, while particulate matter of 2.5 µm did not elicit changes. Particulate matter of 2.5 µm reduced epithelial mucous and epithelium thickness, while total suspended particles behaved similarly to the control group. Total suspended particles exhibited a predominance of Fe and no organic compounds, while the particulate matter 2.5 µm contained predominant amounts of S, Fe, Si and, to a lesser extent, Cu, Ni, V, Zn and organic compounds.CONCLUSION:Our results showed that different compositions of particles induced different airway epithelial responses, emphasizing that knowledge of their individual characteristics may help to establish policies aimed at controlling air pollution.

    Full Text Available This article provides examples of adverse health effects, including weather-related injury, food insecurity, mental health issues, and water infrastructure damage, and the responses to these effects that are currently being applied in two Northwest Alaska communities.In Northwest Alaska, warming is resulting in a broad range of unusual weather and environmental conditions, including delayed freeze-up, earlier breakup, storm surge, coastal erosion, and thawing permafrost. These are just some of the climate impacts that are driving concerns about weather-related injury, the spread of disease, mental health issues, infrastructure damage, and food and water security. Local leaders are challenged to identify appropriate adaptation strategies to address climate impacts and related health effects.The tribal health system is combining local observations, traditional knowledge, and western science to perform community-specific climate change health impact assessments. Local leaders are applying this information to develop adaptation responses.The Alaska Native Tribal Health Consortium will describe relationships between climate impacts and health effects and provide examples of community-scaled adaptation actions currently being applied in Northwest Alaska.Climate change is increasing vulnerability to injury, disease, mental stress, food insecurity, and water insecurity. Northwest communities are applying adaptation approaches that are both specific and appropriate.The health impact assessment process is effective in raising awareness, encouraging discussion, engaging partners, and implementing adaptation planning. With community-specific information, local leaders are applying health protective adaptation measures.

    Full Text Available OBJECTIVE: To describe and characterize local adverse effects (in the oral cavity, pharynx, and larynx associated with the use of inhaled corticosteroids (ICSs in patients with moderate or severe asthma. METHODS: This was a cross-sectional study involving a convenience sample of 200 asthma patients followed in the Department of Pharmaceutical Care of the Bahia State Asthma and Allergic Rhinitis Control Program Referral Center, located in the city of Salvador, Brazil. The patients were ≥ 18 years of age and had been using ICSs regularly for at least 6 months. Local adverse effects (irritation, pain, dry throat, throat clearing, hoarseness, reduced vocal intensity, loss of voice, sensation of thirst, cough during ICS use, altered sense of taste, and presence of oral candidiasis were assessed using a 30-day recall questionnaire. RESULTS: Of the 200 patients studied, 159 (79.5% were women. The mean age was 50.7 ± 14.4 years. In this sample, 55 patients (27.5% were using high doses of ICS, with a median treatment duration of 38 months. Regarding the symptoms, 163 patients (81.5% reported at least one adverse effect, and 131 (65.5% had a daily perception of at least one symptom. Vocal and pharyngeal symptoms were identified in 57 (28.5% and 154 (77.0% of the patients, respectively. The most commonly reported adverse effects were dry throat, throat clearing, sensation of thirst, and hoarseness. CONCLUSIONS: Self-reported adverse effects related to ICS use were common among the asthma patients evaluated here.

    Full Text Available BACKGROUND: After the introduction of the multidrug therapy, there was a decline in the coefficients of prevalence and detection of new cases of leprosy. However, the records of drug resistance and relapses are threatening factors in leprosy control. Hence, new alternative schemes and monitoring of adverse effects to avoid treatment abandonment are important considerations. OBJECTIVE: Describe the side effects of a multidrug regimen containing minocycline, ofloxacin, and clofazimine in multibacillary leprosy patients. METHODS: We conducted a prospective, descriptive, and observational study with multibacillary patients, including cases of intolerance to standard MDT and relapses. The study was carried out at Fundação Alfredo da Matta (Alfredo da Matta Foundation, in Manaus, Amazonas, from April 2010 to January 2012. The patients received alternative therapy, which consisted of daily self-administered doses of 100mg of minocycline, 400 mg of ofloxacin, and 50mg of clofazimine and a supervised monthly dose of 300mg of clofazimine for six months, followed by eighteen months of daily doses of ofloxacin 400mg, clofazimine 50mg, and a supervised monthly dose of clofazimine 300mg. Results: Twenty-one cases were included. Mild and transitory side effects occurred in 33.3% of patients. Of the total episodes, 45.9% were attributed to ofloxacin and they included abdominal pain, nausea, vomiting, headache, and insomnia; 21.6% were due to clofazimine, with 100% of patients presenting skin pigmentation. The mean time for the development of adverse effects after beginning the therapy was 15.2 days. CONCLUSION: All patients tolerated the drugs well, and compliance was satisfactory, with no serious events. Unlike other standard MDT studies had shown, no treatment was stopped due to side effects. Nevertheless, patient follow-up and studies with bigger samples are necessary to guarantee the efficacy and safety of the alternative regimen as a second-line scheme

    This study aimed to examine the relationship between three indicators of family adversity (domestic violence, family substance use, and broken parental marriage) and the severity of social anxiety among adolescents in Taiwan, as well as the mediating effects of perceived family function and self-esteem on that relationship, using structural equation modeling (SEM). A total of 5607 adolescents completed the social anxiety subscale of the Multidimensional Anxiety Scale for Children; the Family APGAR Index; the Rosenberg Self-Esteem Scale; and a questionnaire for domestic violence, family substance use, and broken parental marriage. The relation between family adversity and social anxiety, as well as the mediating effects of family function and self-esteem, was examined using SEM. SEM analysis revealed that all three indicators of family adversity reduced the level of family function, that decreased family function compromised the level of self-esteem, and that a low level of self-esteem further increased the severity of social anxiety. The results indicated that, along with intervening to change family adversity, evaluating and improving adolescents' self-esteem and family function are also important clinical issues when helping adolescents reduce their social anxiety.

  20. Ozone health effects

    International Nuclear Information System (INIS)

    Ozone is a principal component of photochemical air pollution endogenous to numerous metropolitan areas. It is primarily formed by the oxidation of NOx in the presence of sunlight and reactive organic compounds. Ozone is a highly active oxidizing agent capable of causing injury to the lung. Lung injury may take the form of irritant effects on the respiratory tract that impair pulmonary function and result in subjective symptoms of respiratory discomfort. These symptoms include, but are not limited to, cough and shortness of breath, and they can limit exercise performance. The effects of ozone observed in humans have been primarily limited to alterations in respiratory function, and a range of respiratory physiological parameters have been measured as a function of ozone exposure in adults and children. These affects have been observed under widely varying (clinical experimental and environmental settings) conditions

  3. Adverse effects of brain irradiation correlated with MR and CT imaging

    International Nuclear Information System (INIS)

    Forty-one patients treated for primary malignancies of the brain at the University of Rochester Cancer Center since 1970 were assessed for adverse effects of irradiation clinically, and by computerized tomography (CT) and magnetic resonance (MR) imaging. At diagnosis, patients ranged in age from 1-65 years (median 19 years) and the most common tumor (in 30) was astrocytoma. Radiation doses ranged from 45 to 81.3 Gy (median 56.8 Gy). White matter changes visible on MR were graded on a scale of 1-4, with grades 1-2 known to occur in some normal patients. Areas of increased signal intensity not associated with the tumor or surgery were visible in all patients (gr 1 = 37%, gr 2 = 32%, gr 3 = 17%, gr 4 = 15%) whereas only 35% had regions of abnormality (hypodensity) on CT. Sulci enlargement and ventricular abnormalities (asymmetry or dilatation) were present in approximately 50% of patients by each technique. Higher grade MR lesions were associated with radiation to large volumes and high doses. For the 36 patients treated with 1.5-2.0 Gy daily fractions, the mean radiation dose by grade was as follows: gr 1 = 55.1 Gy, gr 2 = 58.8 Gy, gr 3 = 60.0 Gy, gr 4 = 63.5 Gy. All 5 patients treated on a hyperfractionated schedule had gr 1-2 changes despite receiving greater than 70 Gy. Fifty percent of patients treated to the whole brain (+/- boost) had gr 3-4 changes, compared with 14% treated with local fields (peak dose regions similar in both groups). Among the children (less than or equal to 13 years), 20% had gr 3-4 changes compared with 56% of adults (excluding hyperfractionated patients). This finding may be due entirely or in part to the lower radiation doses used for children (mean 54.4 Gy vs. 63.7 Gy in adults). Clinical abnormalities attributable to irradiation included an impairment in mental functioning in 7 adults, and learning disabilities in 5 children

  5. Air pollution epidemiology. Assessment of health effects and risks

    1995-12-31

    Air pollution epidemiology is the study of the occurrence and distribution of health outcomes in association with community air pollution exposure. It is therefore specific in the exposure variable. Air pollution health effects became evident during high air pollution episodes which occurred in the first decades of our century. Since then, legal and other control measures have led to lower air pollution levels. However, recent results from several studies indicate that lower levels of air pollution than the previously considered safe have serious adverse health effects. Although, there is increasingly agreement that air pollution, at levels measured today, affects health, there is still a lot to be understood concerning specific causal pollutants, biologic mechanisms involved and sensitive groups of individuals. The extent of potential confounding, time-considerations in air pollution effects, individual variation in air pollution exposure and exposure misclassification are some factors which complicate the study of these issues.

  6. Chernobyl health effects

    International Nuclear Information System (INIS)

    On 26 April 1986, a few short minutes were not enough to destroy one of the four nuclear reactors at Chernobyl and cause, over the next few weeks, the deaths of 31 people from among the staff, rescuers and firefighters who had dealt with the accident and prevented the spread of the catastrophe to the other three reactors on the site. The experts and the authorities soon recognized that the consequences of this event for the environment and for the surrounding populations would last several decades. Forecast estimates from very diverse sources of the nature and extent of these consequences came thick and fast, particularly in the years 1986 and 1987. Unfortunately, they differed so greatly in both time and space that they lacked all credibility. As the news spread through the public, it could only worsen a social climate which was already seriously upset by the effects of the catastrophe itself. 55 refs

  7. Are hand preference and sexual orientation possible predicting factors for finasteride adverse effects in male androgenic alopecia?

    Sexual side effects of finasteride seem to be redoubtable, being encountered not only during therapy but also after treatment cessation. Consequently, any possible clinical/paraclinical elements that might predict these adverse effects would be useful in the selection of a therapeutic strategy for male androgenic alopecia. Previous published studies show that some compounds that interfere with sexual hormones can decrease sexual activation and response, according to hand preference (as reported for finasteride and tamoxifen) and according to sexual orientation (as noted for bicalutamide). Our preliminary published data and the arguments presented here suggest that these two individual parameters might be used by dermatologists in the therapeutic approach of male androgenic alopecia, so as to alert specific subsets of men, prior to treatment, of the potential increased risk for developing adverse effects to finasteride.

    Full Text Available Early life adversity can have a significant long-term impact with implications for the emergence of psychopathology. Disruption to mother-infant interactions is a form of early life adversity that may, in particular, have profound programming effects on the developing brain. However, despite converging evidence from human and animal studies, the precise mechanistic pathways underlying adversity-associated neurobehavioral changes has yet to be elucidated. One approach to the study of mechanism is exploration of epigenetic changes associated with early life experience. In the current study, we examined the effects of postnatal maternal separation in mice and assessed the behavioral, brain gene expression, and epigenetic effects of this manipulation in offspring. Importantly, we included two different mouse strains (B6 and Balb/c and both male and female offspring to determine strain- and/or sex-associated differential response to maternal separation. We found both strain-specific and sex-dependent effects of maternal separation in early adolescent offspring on measures on open-field exploration, sucrose preference, and social behavior. Analyses of cortical and hippocampal mRNA levels of the glucocorticoid receptor (Nr3c1 and brain-derived neurotrophic factor (Bdnf genes revealed decreased hippocampal Bdnf expression in maternally-separated B6 females and increased cortical Bdnf expression in maternally separated male and female Balb/c offspring. Analyses of Nr3c1and Bdnf (IV and IX CpG methylation indicated increased hippocampal Nr3c1 methylation in maternally separated B6 males and increased hippocampal Bdnf IX methylation in male and female maternally separated Balb/c mice. Overall, though effect sizes were modest, these findings suggest a complex interaction between early life adversity, genetic background, and sex in the determination of neurobehavioral and epigenetic outcomes that may account for differential vulnerability to later life

    Full Text Available The development of in vitro testing strategies may achieve a cost-effective generation of comprehensive datasets on a large number of chemicals, according to the requirements of the European Regulation REACH. Much emphasis is placed on in vitro methods based on subcellular mechanisms (e.g., nuclear receptor interaction, but it is necessary to define the predictive value of molecular or biochemical changes within an adverse outcome pathway (AOP. AOP pivots on the description of the flow from a molecular initiating event through a cascade of intermediate events needed to produce a specific adverse effect at organism level: downstream responses at cell level are, therefore, essential to define an AOP. Several in vitro assays are based on human cell lines representative of endocrine-targeted tissues (e.g., prostate and on functional biomarkers of clinical relevance (e.g., PSA secretion in human prostate epithelial cells. We discuss the implementation of such functional biomarkers in the AOP context.

    Full Text Available BACKGROUND: Giardia duodenalis infection and malnutrition are still considered as public health problems in many developing countries especially among children in rural communities. This study was carried out among Aboriginal (Orang Asli primary schoolchildren in rural peninsular Malaysia to investigate the burden and the effects of Giardia infection on growth (weight and height of the children. METHODS/FINDINGS: Weight and height of 374 children aged 7-12 years were assessed before and after treatment of Giardia infection. The children were screened for Giardia parasite using trichrome staining technique. Demographic and socioeconomic data were collected via face-to-face interviews using a pre-tested questionnaire. Overall, 22.2% (83/374 of the children were found to be infected with Giardia. Nutritional status of children was assessed and the results showed that the mean weight and height were 23.9 kg (95% CI = 23.3, 24.5 and 126.6 cm (95% CI = 125.6, 127.5, respectively. Overall, the prevalence of severe underweight, stunting and wasting were 28.3%, 23.8% and 21.0%, respectively. Multiple linear regression analyses showed sex, Giardia infection and household monthly income as the significant determinants of weight while sex and level of mother's education were the significant determinants of height. Weight and height were assessed at 3 and 6 months after treatment of Giardia infection. It was found that Giardia infection has a significant association with the weight of children but not with height. CONCLUSIONS/SIGNIFICANCE: This study reveals high prevalence of Giardia infection and malnutrition among Aboriginal children in rural Malaysia and clearly highlights an urgent need to identify integrated measures to control these health problems in the rural communities. Essentially, proper attention should be given to the control of Giardia infection in Aboriginal communities as this constitutes one of the strategies to improve the

    Gastroesophageal reflux (GER) is commonly observed in children, particularly during the first year of life. Pharmacological therapy is mostly reserved for symptomatic infants diagnosed with GER disease (GERD), usually as defined in a recent consensus statement. The purpose of the present article was to review the reported adverse effects of pharmacological agents used in the treatment of paediatric GERD. We conducted this review using the electronic journal database Pubmed and Cochrane database systematic reviews using the latest 10-year period (1 January 2003 to 31 December 2012). Our search strategy included the following keywords: omeprazole, esomeprazole, lansoprazole, pantoprazole, rabeprazole, rantidine, cimetidine, famotidine, nizatidine, domperidone, metoclopramide, betanechol, erythromycin, baclofen, alginate. We used Pubmed's own filter of: 'child: birth-18 years'. All full articles were reviewed and we only included randomized controlled trials retrieved from our search. We addressed a summary of our search on a drug-by-drug basis with regard to its mechanism of action and clinical applications, and reviewed all of the adverse effects reported and the safety profile of each drug. Adverse effects have been reported in at least 23% of patients treated with histamine H2 receptor antagonists (H2 RAs) and 34% of those treated with proton pump inhibitors (PPIs), and mostly include headaches, diarrhoea, nausea (H2 RAs and PPIs) and constipation (PPIs). Acid suppression may place immune-deficient infants and children, or those with indwelling catheters, at risk for the development of lower respiratory tract infections and nosocomial sepsis. Prokinetic agents have many adverse effects, without major benefits to support their routine use. PMID:25752807
