    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. PMID:26457296

  2. Probable Nootropicinduced Psychiatric Adverse Effects: A Series of Four Cases

    2015-01-01

    The misuse of nootropics—any substance that may alter, improve, or augment cognitive performance, mainly through the stimulation or inhibition of certain neurotransmitters—may potentially be dangerous and deleterious to the human brain, and certain individuals with a history of mental or substance use disorders might be particularly vulnerable to their adverse effects. 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.

    of reports, while for ofloxacin and pefloxacin, the number of reports may be over-representative. A total of 232 ADRs were identified from the selected articles, with 206 of these related to psychiatric and/or neurological ADRs. The other 26 were related to other body systems but were reported together with the reactions of interest. Mania, insomnia, acute psychosis and delirium were the most frequently reported psychiatric adverse events; grand mal convulsion, confusional state, convulsions and myoclonus were the most frequently reported neurological adverse events. Several aspects should be taken into account in the development of CNS adverse effects, such as the pharmacokinetics of quinolones, chemical structure and quinolone uptake in the brain. These events may affect not only susceptible patients but also 'healthy' patients.

  5. When the safe place does not protect: reports of victimisation and adverse experiences in psychiatric institutions.

    Psychiatric patients report higher levels of victimisation and are at risk for further victimisation in different contexts, such as psychiatric institutions. Studies in this field tend to focus on hospital staff as victims, experiencing classic forms of victimisation (e.g. physical assault, threats, verbal abuse), through qualitative studies. This is a quantitative retrospective study that aims to know the occurrence of psychiatric victimisation and other adverse experiences in Portuguese psychiatric patients. Ninety-five psychiatric patients, between 20 and 79 years old (M - 45.18, SD - 13.06), with a history of psychiatric hospitalisation answered the Experiences in Psychiatric Institution Inventory. Participants were recruited in four psychiatric hospitals. Inpatients were approached during their hospitalisation; outpatients were approached in scheduled appointment days. Only 23 (24.2%) participants reported no victimisation. Total Experiences of Self varied from 0 to 7 (M - 1.75, SD - 1.72), Total Witnessed Experiences varied from 0 to 7 (M - 1.17, SD - 1.64), and Total Global Experiences varied from 0 to 14 (M - 2.92, SD - 3.01). These results show that victimisation and adverse experiences in psychiatric contexts are frequent and go beyond classic forms of victimisation. A deeper knowledge of these experiences and their impact in the mental health of psychiatric patients may promote quality of care provided and lead to more effective treatments, thus reducing the number and length of hospitalisations, and the financial burden for public health services.

    Aripiprazole is a partial dopamine agonist with only minor neurological and psychiatric adverse effects, making it a potential first-line drug for the treatment of psychiatric disorders. However, the evidence of its use in children and adolescents is rather sparse. The aim of this case study is to discuss adverse drug reaction (ADR) reports concerning aripiprazole-associated neurological and psychiatric events in children and adolescents. The ADR report database at Danish Medicines Agency was searched for all ADRs involving children and adolescents (<18 years) reported by the search term [aripiprazole] AND all spontaneous reports since the introduction of aripiprazole in 2003 until December 31, 2015. Nineteen case reports were included in the study and included both patients with psychotic disorders (PS group) and nonpsychotic disorders (non-PS group). The PS group consisted of 5 patients with schizophrenia and psychoses, not otherwise specified; and the non-PS group consisted of fourteen cases including autism spectrum disorders, attention deficit and hyperactivity disorder, obsessive-compulsive disorder, and Tourette syndrome. The main reported adverse effects in the non-PS group were chronic insomnia, Parkinsonism, behavioral changes psychoses, and weight gain, whereas the adverse effects in the PS group was predominantly anxiety, convulsions, and neuroleptic malignant syndrome. Although aripiprazole is considered safe and well tolerated in children and adolescents, severe adverse events as neuroleptic malignant syndrome, extreme insomnia, and suicidal behavior has been reported to health authorities. Clinicians should pay attention to these possible hazards when prescribing aripiprazole to this vulnerable group of patients.

    The NASA commitment to human space flight includes continuing to fly astronauts on the ISS until it is decommissioned as well as possibly returning astronauts to the moon or having astronauts venture to an asteroid or Mars. As missions leave low Earth orbit and explore deeper space, BHP supports and conducts research to enable a risk posture that considers the risk of adverse cognitive or behavioral conditions and psychiatric disorders “acceptable given mitigations,” for pre-, in, and post-flight.The Human System Risk Board (HSRB) determines the risk of various mission scenarios using a likelihood (per person per year) by consequences matrix examining those risks across two categories—long term health and operational (within mission). Colors from a stoplight signal are used by HSRB and quickly provide a means of assessing overall perceived risk for a particular mission scenario. Risk associated with the current six month missions on the ISS are classified as “accepted with monitoring” while planetary missions, such as a mission to Mars, are recognized to be a “red” risk that requires mitigation to ensure mission success.Currently, the HSRB deems that the risk of adverse cognitive or behavioral conditions and psychiatric outcomes requires mitigation for planetary missions owing to long duration isolation and radiation exposure (see Table 1). While limited research evidence exists from spaceflight, it is well known anecdotally that the shift from the two week shuttle missions to the six month ISS missions renders the psychological stressors of space as more salient over longer duration missions. Shuttle astronauts were expected just to tolerate any stressors that arose during their mission and were successful at doing so (Whitmire et al, 2013). While it is possible to deal with stressors such as social isolation and to live with incompatible crewmembers for two weeks on shuttle, “ignoring it” is much less likely to be a successful coping mechanism

    The purpose of this paper is to estimate the impact of chronic adversity on psychopathology in adolescents, taking into account the type of adversity, number of adversities experienced and type of psychiatric disorder, as well as to estimate the impact on severity of the disorder. A total of 3,005 male and female adolescents from the Mexican Adolescent Mental Health Survey aged 12-17 years were interviewed in a stratified multistage general population probability survey. Assessment of 20 DSM-IV disorders, disorder severity and 12 chronic childhood adversities were assessed with the adolescent version of the World Mental Health Composite International Diagnostic Interview (WMH-CIDI-A). Family dysfunction adversities including abuse presented the most consistent associations between chronic adversity and psychopathology and their impact was generally non-specific with regard to the type of disorder. Parental divorce, parental death and economic adversity were not individually associated with psychopathology. Among those with a psychiatric disorder, sexual abuse and family violence were associated with having a seriously impairing disorder. The odds of having a psychiatric disorder and a serious disorder increased with increasing numbers of adversities; however, each additional adversity increased the odds at a decreasing rate. While the study design does not allow for conclusions regarding causality, these findings suggest general pathways from family dysfunction to psychopathology rather than specific associations between particular adversities and particular disorders, and provide further evidence for the importance of family-focused intervention and prevention efforts.

  9. Adverse effects of cannabis.

    2011-01-01

    Cannabis, Cannabis sativa L., is used to produce a resin that contains high levels of cannabinoids, particularly delta9-tetrahydrocannabinol (THC), which are psychoactive substances. Although cannabis use is illegal in France and in many other countries, it is widely used for its relaxing or euphoric effects, especially by adolescents and young adults. What are the adverse effects of cannabis on health? During consumption? And in the long term? Does cannabis predispose users to the development of psychotic disorders? To answer these questions, we reviewed the available evidence using the standard Prescrire methodology. The long-term adverse effects of cannabis are difficult to evaluate. Since and associated substances, with or without the user's knowledge. Tobacco and alcohol consumption, and particular lifestyles and behaviours are often associated with cannabis use. Some traits predispose individuals to the use of psychoactive substances in general. The effects of cannabis are dosedependent.The most frequently report-ed adverse effects are mental slowness, impaired reaction times, and sometimes accentuation of anxiety. Serious psychological disorders have been reported with high levels of intoxication. The relationship between poor school performance and early, regular, and frequent cannabis use seems to be a vicious circle, in which each sustains the other. Many studies have focused on the long-term effects of cannabis on memory, but their results have been inconclusive. There do not * About fifteen longitudinal cohort studies that examined the influence of cannabis on depressive thoughts or suicidal ideation have yielded conflicting results and are inconclusive. Several longitudinal cohort studies have shown a statistical association between psychotic illness and self-reported cannabis use. However, the results are difficult to interpret due to methodological problems, particularly the unknown reliability of self-reported data. It has not been possible to

    Objective: To investigate the incidence of serious adverse events (SAE) of subthalamic deep brain stimulation (STN-DBS) in elderly patients with Parkinson's disease (PD). Methods: We investigated a group of 26 patients with PD who underwent STN-DBS at mean age 63.2 ± 3.3 years. The operated patients from the EARLYSTIM study (mean age 52.9 ± 6.6) were used as a comparison group. Incidences of SAE were compared between these groups. Results: A higher incidence of psychosis and hallucinations was found in these elderly patients compared to the younger patients in the EARLYSTIM study (p < 0.01). Conclusions: The higher incidence of STN-DBS-related psychiatric complications underscores the need for comprehensive psychiatric pre- and postoperative assessment in older DBS candidates. However, these psychiatric SAE were transient, and the benefits of DBS clearly outweighed its adverse effects. PMID:27375478

  12. Enduring psychobiological effects of childhood adversity.

    PubMed

    2013-09-01

    This mini-review refers to recent findings on psychobiological long-term consequences of childhood trauma and adverse living conditions. The continuum of trauma-provoked aftermath reaches from healthy adaptation with high resilience, to severe maladjustment with co-occurring psychiatric and physical pathologies in children, adolescents and adults. There is increasing evidence of a strong interconnectivity between genetic dispositions, epigenetic processes, stress-related hormonal systems and immune parameters in all forms of (mal)-adjustment to adverse living conditions. Unfavorable constellations of these dispositions and systems, such as low cortisol levels and elevated markers of inflammation in maltreated children, seem to promote the (co)-occurrence of psychiatric and physical pathologies such as posttraumatic stress disorder, obesity, or diabetes. Although findings from prospective study designs support a deepened understanding of causal relations between adverse living conditions, including traumatic experiences, during childhood and its psychobiological effects, so far, little is known about the temporal coincidence of stress-sensitive developmental stages during childhood and adolescence and trauma consequences. Taken together, childhood adversity is a severe risk factor for the onset of psychobiological (mal)-adjustment, which has to be explained under consideration of diverse physiological systems and developmental stages of childhood and adolescence.

  13. Telithromycin: review of adverse effects.

    PubMed

    2014-11-01

    Telithromycin is a macrolide antibiotic that has been marketed since the early 2000s. It has not been shown to be more effective against any bacteria than other macrolide antibiotics. Its antibacterial activity is in no way remarkable. In early 2014, we reviewed its adverse effect profile using data from periodic safety update reports, drug regulatory agencies, and detailed published case reports. In addition to the adverse effect profile telithromycin shares with the other macrolides, it provokes several specific adverse effects: visual disturbances due to impaired accommodation; taste and smell disorders; severe liver damage; worsening of myasthenia gravis; rhabdomyolysis; and loss of consciousness. Prolongation of the QT interval with standard oral doses is a worrisome adverse effect. In practice, it is better not to use telithromycin as it exposes patients to disproportionate, serious adverse effects. When treatment with a macrolide antibiotic appears necessary, it is prudent to choose a different macrolide, such as spiramycin or azithromycin, which have fewer adverse effects.

  14. Neuropsychiatric Adverse Effects of Amphetamine and Methamphetamine.

    PubMed

    Harro, Jaanus

    2015-01-01

    Administration of amphetamine and methamphetamine can elicit psychiatric adverse effects at acute administration, binge use, withdrawal, and chronic use. Most troublesome of these are psychotic states and aggressive behavior, but a large variety of undesirable changes in cognition and affect can be induced. Adverse effects occur more frequently with higher dosages and long-term use. They can subside over time but some persist long-term. Multiple alterations in the gray and white matter of the brain assessed as changes in tissue volume or metabolism, or at molecular level, have been associated with amphetamine and methamphetamine use and the psychiatric adverse effects, but further studies are required to clarify their causal role, specificity, and relationship with preceding states and traits and comorbidities. The latter include other substance use disorders, mood and anxiety disorders, attention deficit hyperactivity disorder, and antisocial personality disorder. Amphetamine- and methamphetamine-related psychosis is similar to schizophrenia in terms of symptomatology and pathogenesis, and these two disorders share predisposing genetic factors.

  15. Adverse psychosocial working conditions and minor psychiatric disorders among bank workers

    PubMed Central

    2010-01-01

    Background In most countries, the financial service sector has undergone great organizational changes in the past decades, with potential negative impact on bank workers' mental health. The aim of this paper is to estimate the prevalence of minor psychiatric disorders (MPD) among Brazilian bank workers and to investigate whether they are associated with an adverse psychosocial working environment. Methods A cross-sectional study of a random sample of 2,500 workers in a Brazilian state bank in 2008. The presence of MPD was determined by the General Health Questionnaire.(GHQ). Psychosocial work conditions were assessed by means of the Effort-Reward Imbalance (ERI) and Job Content Questionnaire (JCQ). The presence and magnitude of the independent associations between MPD and adverse psychosocial working conditions were determined by Prevalence Ratios, obtained by Poisson regression. Results From 2,337 eligible workers, 88% participated. The prevalence of MPD was greater among women (45% vs. 41%; p > 0.05). In the multivariate analysis, the prevalence of MPD was twice as high among bank workers exposed to high psychological demand and low control at work and under high effort and low reward working conditions. The lack of social support at work and the presence of over-commitment were also associated with higher prevalence of MPD. A negative interaction effect was found between over-commitment and effort-reward imbalance. Conclusion The prevalence of MPD is high among bank workers. The results reinforce the association between MPD and adverse psychosocial working conditions, assessed by the JCQ and ERI models. The direction of the interaction observed between over-commitment and ERI was contrary to what was expected. PMID:21062496

    In April 2010, President Obama declared a space pioneering goal for the United States in general and NASA in particular. "Fifty years after the creation of NASA, our goal is no longer just a destination to reach. Our goal is the capacity for people to work and learn and operate and live safely beyond the Earth for extended periods of time, ultimately in ways that are more sustainable and even indefinite." Thus NASA's Strategic Objective 1.1 emerged as "expand human presence into the solar system and to the surface of Mars to advance exploration, science, innovation, benefits to humanity, and international collaboration" (NASA 2015b). Any space flight, be it of long or short duration, occurs in an extreme environment that has unique stressors. Even with excellent selection methods, the potential for behavioral problems among space flight crews remain a threat to mission success. Assessment of factors that are related to behavioral health can help minimize the chances of distress and, thus, reduce the likelihood of adverse cognitive or behavioral conditions and psychiatric disorders arising within a crew. Similarly, countermeasures that focus on prevention and treatment can mitigate the cognitive or behavioral conditions that, should they arise, would impact mission success. Given the general consensus that longer duration, isolation, and confined missions have a greater risk for behavioral health ensuring crew behavioral health over the long term is essential. Risk, which within the context of this report is assessed with respect to behavioral health and performance, is addressed to deter development of cognitive and behavioral degradations or psychiatric conditions in space flight and analog populations, and to monitor, detect, and treat early risk factors, predictors and other contributing factors. Based on space flight and analog evidence, the average incidence rate of an adverse behavioral health event occurring during a space mission is relatively low for the

  17. Thiocolchicoside: review of adverse effects.

    PubMed

    2016-02-01

    Thiocolchicoside has long been used as a muscle relaxant, despite a lack of proven efficacy beyond the placebo effect. Its chemical structure consists of colchicine, a sugar (ose) and a sulphur-containing radical (thio), and its adverse effects are therefore likely to be similar to those of colchicine. Using the standard Prescrire methodology, we reviewed the available data on the adverse effects of thiocolchicoside. Liver injury, pancreatitis, seizures, blood cell disorders, severe cutaneous disorders, rhabdomyolysis and reproductive disorders have all been recorded in the French and European pharmacovigilance databases and in the periodic updates that the companies concerned submit to regulatory agencies. These data do not specify the frequency of the disorders nor do they identify the most susceptible patient populations. Thiocolchicoside is teratogenic in experimental animals and also damages chromosomes. Human data are limited to a follow-up of about 30 pregnant women (no major malformations) and reports of altered spermatogenesis, including cases of azoospermia. In practice, there is no justification for exposing patients to the adverse effects of thiocolchicoside. It is better to use an effective, well-known analgesic for patients complaining of muscle pain, starting with paracetamol.

    Early essential hypertension is asymptomatic and should remain so throughout treatment. In view of the increasing number of available antihypertensive agents, clinicians need to become familiar with the potential side effects of these drugs. By placing more emphasis on non-pharmacological treatment (sodium restriction, weight loss, exercise) and thoroughly evaluating each case in particular, the pharmacological regimen can be optimally tailored to the patient's needs. Potential side effects should be predicted and can often be avoided; if they become clinically significant they should be rapidly recognised and corrected. These side effects can be easily remembered in most instances, as they fall into 3 broad categories: (a) those caused by an exaggerated therapeutic effect; (b) those due to a non-therapeutic pharmacological effect; and (c) those caused by a non-therapeutic, non-pharmacological effect probably representing idiosyncratic reactions. This review focuses mainly on adverse effects of the second and third kind. Each group of drugs in general shares the common side effects of the first two categories, while each individual drug has its own idiosyncratic side effects.

    Anabolic-androgenic steroids (AAS) are used as ergogenic aids by athletes and non-athletes to enhance performance by augmenting muscular development and strength. AAS administration is often associated with various adverse effects that are generally dose related. High and multi-doses of AAS used for athletic enhancement can lead to serious and irreversible organ damage. Among the most common adverse effects of AAS are some degree of reduced fertility and gynecomastia in males and masculinization in women and children. Other adverse effects include hypertension and atherosclerosis, blood clotting, jaundice, hepatic neoplasms and carcinoma, tendon damage, psychiatric and behavioral disorders. More specifically, this article reviews the reproductive, hepatic, cardiovascular, hematological, cerebrovascular, musculoskeletal, endocrine, renal, immunologic and psychologic effects. Drug-prevention counseling to athletes is highlighted and the use of anabolic steroids is must be avoided, emphasizing that sports goals may be met within the framework of honest competition, free of doping substances.

    Deep brain stimulation (DBS) has been approved by the FDA for use in the treatment of Parkinson's disease, essential tremor, and dystonia. Case reports and case series have reported significant psychiatric side effects in some individuals. The goal of this meta-analysis is to characterize the risks and benefits of DBS and to assess its possible use within the psychiatric setting. A search was conducted on PubMed, EBSCO, and PsycInfo in January 2006 that covered the time period 1 Jan 1996-30 Dec 2005. All identified articles were reviewed and those describing adverse events were further examined with a structured instrument. The initial searches yielded 2667 citations; 808 articles met inclusion criteria for the meta-analysis; 98.2% of studies that specifically assessed motor function reported some level of improvement. Most reported side effects were device or procedure related (e.g., infection and lead fracture). The prevalence of depression was 2-4%, mania 0.9-1.7%, emotional changes 0.1-0.2%, and the prevalence of suicidal ideation/suicide attempt was 0.3-0.7%. The completed suicide rate was 0.16-0.32%. In conclusion, DBS is an effective treatment for Parkinson's disease, dystonia, and essential tremor, and case reports suggest that major depression and OCD may also respond to DBS. Reported rates of depression, cognitive impairment, mania, and behavior change are low, but there is a high rate of suicide in patients treated with DBS, particularly with thalamic and GPi stimulation. Because of the high suicide rate, patients should be prescreened for suicide risk prior to DBS surgery. Additionally, patients should be monitored closely for suicidal behavior post-operatively.

    Hypercortisolism is associated with various systemic manifestations, including central obesity, arterial hypertension, glucose intolerance/diabetes mellitus, dyslipidemia, nephrolithiasis, osteoporosis, gonadal dysfunction, susceptibility to infections, psychiatric disorders, and hypercoagulability. The activation of the hemostatic system contributes to the development of atherosclerosis and subsequent cardiovascular morbidity and mortality. Previous studies have identified an increased risk of both unprovoked and postoperative thromboembolic events in patients with endogenous and exogenous Cushing's syndrome (CS). The risk for postoperative venous thromboembolism in endogenous CS is comparable to the risk after total hip or knee replacement under short-term prophylaxis. The mechanisms that are involved in the thromboembolic complications in hypercortisolism include endothelial dysfunction, hypercoagulability, and stasis (Virchow's triad). It seems that at least two factors from Virchow's triad must be present for the occurrence of a thrombotic event in these patients. Most studies have demonstrated that this hypercoagulable state is explained by increased levels of procoagulant factors, mainly factors VIII, IX, and von Willebrand factor, and also by an impaired fibrinolytic capacity, which mainly results from an elevation in plasminogen activator inhibitor 1. Consequently, there is a shortening of activated partial thromboplastin time and increased thrombin generation. For these reasons, anticoagulant prophylaxis might be considered in patients with CS whenever they have concomitant prothrombotic risk factors. However, multicenter studies are needed to determine which patients will benefit from anticoagulant therapy and the dose and time of anticoagulation.

    The recent advance in identifying risk genes has provided an unprecedented opportunity for developing animal models for psychiatric disease research with the goal of attaining translational utility to ultimately develop novel treatments. However, at this early stage, successful translation has yet to be achieved. Here, we review recent advances in modeling psychiatric disease, discuss utility and limitations of animal models, and emphasize the importance of shifting from behavioral analysis to identifying neurophysiological defects, which are likely more conserved across species and thus increase translatability. Looking forward, we envision that preclinical research will align with clinical research to build a common framework of comparable neurobiological abnormalities and form subgroups of patients based on similar pathophysiology. Experimental neuroscience can then use animal models to discover mechanisms underlying distinct abnormalities and develop strategies for effective treatments. PMID:26340119

    Adverse side effects of drugs are a significantly underestimated problem in modern medicine. In this review article, we summarize common adverse side effects of cardiovascular drugs. In particular, we highlight the factors promoting these adverse side effects in patients, including reduced hepatic or renal clearance in elderly patients that often requires dosage adjustment. Pharmacodynamic and pharmacokinetic interactions between drugs (e.g. through the cytochrome P450 system or P-glycoproteins) can modify the plasma concentration of many compounds, thereby also increasing the likelihood of unwanted side effects. The most prominent cardiac side effects include arrhythmias, e.g. atrioventricular (AV) block, drug-induced long-QT syndrome and torsade de pointes and altered inotropy. Non-cardiac side effects are subsequently discussed grouped by drug class. A better understanding of the risks and side effects of cardiovascular drugs is expected to reduce the mortality and morbidity associated with adverse side effects.

    In Fiji, kava is also known as yaqona or grog. A convenient sample of 300 kava drinkers in Nadi, Lautoka, Ba and Sigatoka were studied to see whether local people in Fiji experienced side effects of kava use. Because males usually consume kava in Fiji, we approached specific groups of people and asked them to participate in the survey. To evaluate the side effects of kava consumption, we interviewed housewives of male kava drinkers regarding specific effects of kava. We interviewed these housewives during kava drinking sessions since they were usually not taking part in the kava drinking. We also interviewed employers of these kava drinkers and the market vendors in Nadi Town since they were closely involved with kava drinkers. Wives of kava users felt deprived of basic family needs due to the amount of money spent on kava. In Urban schools, 64% males and 46.2% had tried kava. The present study aims to assess the prevalence of side effects of kava usage among a community sample of kava drinkers in Fiji and to compare the result with some of the side effects provided by other studies. The questionnaire also asked how much kava was consumed and the reasons. Since kava use is very much part of our everyday culture and existence, convincing people to change their behavior and kava consumption is a major tasks. I hope that this study would emphasize the need at a national level to educate people on the harmful effects of kava and the need for the health ministry to view very heavy kava intake as contributing to morbidity in Fiji.

    Marijuana has consistently been reported as the most commonly used illicit substance in the United States each year. Currently, the legalization of marijuana is up for debate across the nation. While marijuana use is prevalent among the adolescent population, research has shown that there can be devastating effects on health and well-being. A review of the literature shows that marijuana use can have a negative impact on physical health, psychological well-being, and multiple psychosocial outcomes. Adolescents who used marijuana more frequently and began using marijuana at an earlier age experienced worse outcomes and long-lasting effects.

    Evaluation of the potential benefits and risks offered by naturally occurring plant estrogens requires investigation of their potency and sites of action when consumed at natural dietary concentrations. Our investigations have examined the effects of a range of natural dietary concentrations of the most potent plant isoflavonoid, coumestrol, using a rat model and a variety of estrogen-dependent tissues and endpoints. Treatments of immature females demonstrated agonistic action in the reproductive tract, brain, and pituitary at natural dietary concentrations. Experiments designed to test for estrogen antagonism demonstrated that coumestrol did not conform to the picture of a classic antiestrogen. However, coumestrol did suppress estrous cycles in adult females. Developmental actions were examined by neonatal exposure of pups through milk of rat dams fed a coumestrol, control, or commercial soy-based diet during the critical period of the first 10 postnatal days or throughout the 21 days of lactation. The 10-day treatment did not significantly alter adult estrous cyclicity, but the 21-day treatment produced in a persistent estrus state in coumestrol-treated females by 132 days of age. In contrast, the 10-day coumestrol treatments produced significant deficits in the sexual behavior of male offspring. These findings illustrate the broad range of actions of these natural estrogens and the variability in potency across endpoints. This variability argues for the importance of fully characterizing each phytoestrogen in terms of its sites of action, balance of agonistic and antagonistic properties, natural potency, and short-term and long-term effects.

  8. Perspective on Lithotripsy Adverse Effects

    Shock wave lithotripsy (SWL) is an effective and without any doubt the least invasive procedure to treat upper urinary tract calculi. Acute complications are rarely reported and do not require specific treatment in most cases. However, one should be aware that energy levels sufficient for stone breakage are capable of damaging tissue as well, and significant hematoma—not only in the kidney but as well in surrounding organs—has been observed. Furthermore, only little is known about the long-term effects of SWL. Some authors have reported an increased incidence of hypertension and possibly also diabetes mellitus. Such chronic diseases—if indeed related to prior SWL—may be a late result of acute SWL-related trauma but the discussion on the underlying pathogenesis is controversial. Many factors have to be considered, such as the natural history of recurrent stone formers, technical principles of SWL, and differences in treatment protocols. Promising studies are currently underway to optimize stone breakage while limiting potential collateral damage. With this progress, SWL remains a safe treatment option for most urinary calculi.

    Objective: Despite limited information related to efficacy in children, psychotropic medications are commonly prescribed as a first-line treatment for a range of psychiatric diagnoses in children in a variety of clinical settings. Usage has increased over the past three decades. Although psychotropic medications are often effective at treating psychiatric symptoms, the risk of adverse effects (AE) in children is unclear. The current research seeks to identify the mental health characteristics of those children at highest risk of experiencing potential AE from psychotropic medications. Methods: Psychotropic medication monitoring checklists were used to record possible AE for 99 pediatric clients in a tertiary mental health residential treatment centre for the duration of one to eight weeks. Client characteristics, including the number of diagnoses and behavioural variables, were explored for predictive value of potential AE observed. Results: Results showed that the total number of potential AE was positively predicted by the number of DSM-IV categories diagnosed, as well as behavioural symptoms of impulsiveness and uncooperativeness. Conclusions: The findings of this study indicate that the number of potential AE from psychotropic medications may be predictable based on client characteristics. Predicting this likelihood during initial assessment can be useful in directing and monitoring treatment, as well as preventing serious events related to medication use. PMID:25320615

  13. Metabolic and adverse effects of diuretics.

    PubMed

    Wilcox, C S

    1999-11-01

    Diuretics are among the most frequently prescribed drugs. They enjoy a very high clinical reputation for safety and efficacy. However, more than 3 decades of clinical investigation have disclosed a number of abnormalities in fluid electrolyte handling, metabolism, and other adverse effects that can complicate therapy with diuretic drugs. Some of these complications are a direct extension of the wanted action of the drug. These include extracellular fluid volume depletion, associated orthostatic hypotension, and prerenal azotemia. Others are not a direct action of the diuretic, but can be explained as an intranephronal compensation to the diuretic action. These include hypokalemia, in part to increased potassium secretion secondary to the enhanced tubular fluid flow and aldosterone secretion induced by diuretic administration. Metabolic abnormalities are usually mild. Hyperglycemia and carbohydrate intolerance have been related to diuretic-induced hypokalemia, which inhibits insulin secretion by the beta cells, and reductions in extracellular fluid volume and cardiac output. This is compounded by increases in catecholamines from sympathetic nerve activity which decrease peripheral glucose utilization. A mild increase in serum cholesterol concentration is seen frequently during initiation of diuretic therapy, but during steady state therapy after 6 to 12 months, values usually return to baseline. Knowledge of the more common adverse effects induced by diuretics helps the physician in predicting patients at risk and taking effective steps to anticipate or treat adverse responses.

  14. Adverse effects of statins - myths and reality.

    Statins reduce cardiovascular mortality and morbidity as well as cardiovascular events in patients with a very high risk of cardiovascular disease (CVD) and also in subjects with high or moderate risk by reducing the levels of low-density lipoprotein cholesterol (LDL-C). Although they are considered to be drugs with a very good safety profile, because of their wide use there are many concerns that their adverse effects might compromise their proven beneficial effects. Therefore this article reviews all the data and provides an evidence- based insight what are the proven adverse effects of statins and what are the "myths" about them. The most important side effects include myopathy and rhabdomyolysis. Another side effect is increased activity of liver tests which occurs occasionally and is reversible. However, recent studies even suggest that statin therapy can improve hepatic steatosis. It is beyond any doubt that statins do slightly increase the incidence of type 2 diabetes mellitus in people with two or more components of metabolic syndrome but the cardiovascular benefits of such a treatment by far exceed this risk. Statin therapy has also been associated with some adverse renal effects, eg. acute renal failure, but recent data suggest even a possible protective effect of these drugs on renal dysfunction. Concerns that statins might increase cancer have not been proven. On the contrary, several studies have indicated a possible benefit of these drugs in patients with different types of cancer. Early concerns about cognitive dysfunction and memory loss associated with statins use could not be proven and most recent data even suggest a possible beneficial effect of statins in the prevention of dementia. Systematic reviews and clinical guidelines suggest that the cardiovascular benefits of statins by far out-weight non-cardiovascular harms in patients with cardiovascular risk.

    Exposure to early life adversity is linked to impaired affective, cognitive, and behavioral functioning and increases risk for various psychiatric and medical conditions. Stress-induced increases in pro-inflammatory cytokines may be a biological mechanism of these effects. Few studies have examined cytokine levels in children experiencing early life adversity, and very little research has investigated cytokines or other markers of inflammation in saliva. In the present study, we examined salivary IL-1β and C-reactive protein (CRP) levels in relation to stress exposure in 40 children aged 3 to 5 years who were enrolled in a larger study of early life adversity. Childhood maltreatment status was assessed via review of child welfare records, and contextual stress exposure, traumatic life event history, and symptoms of psychopathology were assessed via caregiver interviews at a home visit. In a subsequent visit, salivary IL-1β and CRP were obtained before and after participation in four emotion-eliciting tasks. Number of past month contextual stressors, lifetime contextual stressors, and traumatic life events each demonstrated a significant main effect on IL-1β. Baseline IL-1β was positively associated with each of the significant main-effect adversities. Post-challenge IL-1β displayed positive associations with each adversity variable, but were not significant. CRP was not significantly associated with any of the adversity variables. Given evidence suggesting involvement of IL-1β in the neuropathology of psychiatric conditions, these results may have important implications for developmental outcomes. PMID:25997772

    Adverse perinatal and infant outcomes are the leading causes of infant morbidity and mortality in developing countries like Brazil. Among the risk factors are maternal mental disorders. A retrospective longitudinal study was conducted based on passive follow-up using probabilistic record linkage to estimate the prevalence of adverse perinatal and infant outcomes in children of women admitted to a public psychiatric hospital in Rio de Janeiro, Brazil, and who gave birth from 1999 to 2009. Prevalence rates were: low birth weight (27.6%), prematurity (17.4%), malformations (2.5%), stillbirths (4.8%), and neonatal deaths (3.7%). Associated factors were deficient prenatal care, schizophrenia, and low income. The results corroborate the high prevalence of adverse perinatal and infant outcomes in mothers with major mental disorders, and that screening of psychiatric symptoms and specialized care by mental health professionals are essential throughout prenatal and postpartum care.

    Starting with phenobarbital in the 1900s, it took almost 70-80 years to introduce old-generation agents for the treatment of epilepsy. Then, in eleven years, nine more new antiepileptic drugs were added to the armamentarium. These drugs produce a nearly 40-50% decrease in seizure incidence in refractory patients, but few patients have been able to achieve complete freedom from seizures. So the search for more effective drugs with minimal adverse effect profiles will continue. Although the new antiepileptic drugs do not demonstrate a superior efficacy compared to the older ones, they do offer some advantages in terms of tolerability, fewer drug interactions and simpler pharmacokinetics. However, our knowledge concerning their safety profiles can not yet be considered adequate due to the relatively short time these drugs have been on the market and to the limited number of patients exposed to them. The fact that the serious side effects of felbamate and vigabatrine appeared late after marketing should be taken as an important lesson because it implies the potential for unknown side effects at any time during treatment. Antiepileptic drug treatment should begin with diagnosis of the seizure and epileptic syndrome, followed by selection of the drug most appropriate for treatment of the individual patient, and continued with monitoring of not only the seizures but the adverse effect profile as well.

    Objectives: The main objectives are to present the different adverses effects of the immunomodulatory drugs that can impair the quality of life of the immunosupressed patients and study the impact of immunomodualtion on oral diseases. Immunomodulatory drugs have changed the treatment protocols of many diseases where immune functions play a central role, such as rheumatic diseases. Their effect on oral health has not been systematically investigated, however. Study Design: We review current data on the new immunomodulatory drugs from the oral health perspective based on open literature search of the topic. Results: These target specific drugs appear to have less drug interactions than earlier immunomodulating medicines but have nevertheless potential side effects such as activating latent infections. There are some data showing that the new immunomodulatory drugs may also have a role in the treatment of certain oral diseases such as lichen planus or ameliorating symptoms in Sjögren´s syndrome, but the results have not been overly promising. Conclusions: In general, data are sparse of the effect of these new drugs vs. oral diseases and there are no properly powered randomized controlled trials published on this topic. Key words:Immunomodulatory drugs, oral diseases, adverse effects, therapeutic action. PMID:23986016

    This study aimed to determine the prevalence and the clinical correlates of Adverse Childhood Experiences (ACEs) among 158 inpatient youths with two types of severe psychiatric disorders. ACEs were retrospectively collected with the ACEs scale and the List of Threatening Experiences Questionnaire in 77 patients hospitalized for a catatonic syndrome (average age 15.2 years) and 81 for a manic or mixed episode (average age 15.7 years). ACEs were frequent in youths suffering from bipolar disorder type I (BD-I) (58 %) and from catatonia (57 %), with around one quarter exposed to severe abuse (i.e., physical/sexual/emotional abuse or physical/emotional neglect). Youths with BD-I were more likely to be exposed to family violence compared to those with catatonia. Youths who had been exposed to ACEs did not exhibit a more severe presentation or a poorer response to treatment compared to others, either in the bipolar group or in the catatonic group.

    More pharmacovigilance data on agomelatine became available in 2012. The main sources of information were surveillance data from the French national monitoring system, EU periodic safety update reports (PSURs), and the European pharmacovigilance database. The principal adverse effects of agomelatine consist of hepatic, pancreatic, neuropsychiatric, muscular and cutaneous disorders. The harms associated with agomelatine, which has no proven efficacy in depression, clearly outweigh the benefits. Until regulatory agencies decide to withdraw agomelatine from the market, it is up to healthcare professionals to protect patients from this unnecessarily dangerous drug.

    Community pharmacists represent an important pillar for the identification and the reporting of adverse drug effects (ADE}. Thanks to their broad view on the pharmacotherapy, over-the-counter medication included, they contribute greatly to the improvement of drug safety. In principle, the community pharmacy will face three groups of ADE which require specific attention. This article deals with these specific ADE groups and presents some illustrative examples from daily practice. Furthermore, we suggest some solutions to identify potential relevant interactions - including herbal-drug interactions - and give tips for daily practice, along with some often overseen cutaneous ADE.

    Adverse effects are common, bothersome, and a leading cause of discontinuation of treatment. The methodology for evaluating adverse effects of medications has been greatly neglected, however, especially in comparison to the methodology for assessment of efficacy of medications. Existing methods for assessment and reporting of adverse effects have important limitations leading to lack of much-needed data related to adverse effects. Lastly, there is little systematic research into management of most adverse effects. A series of recommendations are made in this article about how to improve identification, assessment, reporting, and management of adverse effects.

    In two independent parent training projects (Kansas and Mississippi), mothers of deviant young children were observed to follow almost all child behaviors with attention. The mothers were then trained to use differential attention procedures to increase their child's appropriate behaviors and to decrease deviant behaviors. Contrary to expectations, the differential attention procedure produced substantial increases in deviant behavior for four of the children. This adverse effect was maintained over many sessions and was replicated in single organism, reversal designs. A fifth child showed no change. A sixth child showed some improvement. However, this effect was not recovered in a second application of differential attention, and the child became worse. The results underline the importance of subject generality in applied behavior analysis and strongly suggest that service programs using operant techniques must carefully evaluate their effects on behavior.

    Objective Several studies have reported that ethnic differences influence psychiatric diagnoses. Some previous studies reported that African Americans and Hispanics are diagnosed with schizophrenia spectrum disorders more frequently than Caucasians, and that Caucasians are more likely to be diagnosed with affective disorders than other ethnic groups. We sought to identify associations between sociodemographic factors and psychiatric diagnosis. Methods We retrospectively examined the medical records of all psychiatric inpatients (ages over 18 years) treated at Kern county mental hospital (n=2,051) between July 2003 and March 2007 for demographic, clinical information, and discharge diagnoses. Results African American and Hispanic males were more frequently diagnosed with schizophrenia spectrum disorders than Caucasians, whereas Caucasian females were more frequently diagnosed with affective disorders than females in the other ethnic groups, suggesting that patient ethnicity and gender may influence clinical diagnoses. Demographic variables, that is, a lower education, failure of marriage, homelessness, and low quality insurance, were found to be significantly associated with a diagnosis of schizophrenia spectrum disorders after adjusting for clinical variables. And, the presence of a family psychiatric history, failure of marriage, not-homelessness, and quality insurance were found to be associated with a diagnosis of affective disorders. Conclusion Our results show that these demographic factors, including ethnicity, have effects on diagnoses in psychiatric inpatients. Furthermore, these variables may help prediction of psychiatric diagnoses. PMID:22993517

    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

    Phenylpropanolamine (PPA) is a sympathomimetic drug similar in structure to amphetamine which, in the United States, is present in over 130 medications, primarily decongestants, cough/cold remedies, and anorectic agents. We have reviewed 37 cases (published in North America and Europe since 1960) that received diagnoses of acute mania, paranoid schizophrenia, and organic psychosis and that were attributed to PPA product ingestion. Of the 27 North American case reports, more reactions followed the ingestion of combination products than preparations containing PPA alone; more occurred after ingestion of over-the-counter products than those obtained by prescription or on-the-street; and more of the cases followed ingestion of recommended doses than overdoses. Groups at particular risk appear to be those with a past or family psychiatric history, children under the age of 6 and post-partum women. Failure to recognize PPA as an etiological agent in the onset of symptoms usually led to a diagnosis of schizophrenia or mania, lengthy hospitalization, and treatment with substantial doses of neuroleptics or lithium. While generally safe at recommended doses, PPA can be hazardous to susceptible individuals and we urge physicians to be alert to the potential for PPA related psychiatric reactions. We have compiled an alphabetized table (Table 1: Prescription and Over-the-Counter Products Containing Phenylpropanolamine) allowing busy clinicians quick access to those drugs containing PPA.

    Tuberculosis has now become a curable disease with chemotherapy. So it is natural that the present issues in tuberculosis management are focused on how to complete standard chemotherapy. In this context, management of adverse effects constitutes an essential part of antituberculosis chemotherapy, as well as directly observed therapy. In this symposium, discussions were held about three major subjects on this issue. First, hepatotoxicity develops frequently and has sometimes fatal outcome, which makes it the most problematic adverse effect. "Management of hepatotoxicity during antituberculosis chemotherapy" was published by the Japanese Society for Tuberculosis (JST) in 2006. Dr. Shinsho Yoshiba evaluated this recommendation and pointed out that the criteria for discontinuation of drug based on AST, ALT and bilirubin levels is too sensitive and the concept of predicting fulminant hepatic failure (FHF) is lacking. He stressed the importance of monitoring serum prothrombin time for predicting FHF. Next, allergic drug reaction such as fever or skin rash often causes distress, although rarely fatal. As isoniazid (INH) and rifampicin (RFP) are key drugs for the cure, readministration of these drugs is often attempted by desensitization therapy. "Recommendation about desensitization therapy of antituberculosis drugs" was also published by JST in 1997. Dr. Yoshihiro Kobashi reported high success rates of 79 percent for INH and 75 percent for RFP according to this recommendation. He also reported correlated factor with the success, such as the longer period from the discontinuation to the desensitization therapy and lower doses of drugs at starting desensitization. Finally, we sometimes experience transient worsening of radiographical findings and general symptoms during antituberculosis chemotherapy. This is presumed to be due to allergic reaction to dead bacilli without requiring discontinuation of the drug. Differential diagnosis includes drug-induced pneumonia requring

    1987-01-01

    Propylthiouracil and methimazole are frequently used in the management of hyperthyroidism. Two patients in whom adverse immunologic effects other than isolated agranulocytosis developed during treatment with propylthiouracil are described. A review of the literature revealed 53 similar cases over a 35-year period. Rash, fever, arthralgias and granulocytopenia were the most common manifestations. Vasculitis, particularly with cutaneous manifestations, occurs and may be fatal. The clinical evidence suggests that an immunologic mechanism is involved. A number of different autoantibodies were reported, but antinuclear antibodies were infrequent, and none of the cases met the criteria for a diagnosis of systemic lupus erythematosus. Thus, the reactions do not represent a true drug-induced lupus syndrome. Current hypotheses and experimental data regarding the cause of the reactions are reviewed. No specific clinical subgroup at high risk can be identified, and manifestations may occur at any dosage and at any time during therapy. Cross-reactivity between the two antithyroid drugs can be expected. Except for minor symptoms (e.g., mild arthralgias or transient rash), such reactions are an indication for withdrawal of the drug and the use of alternative methods to control the hyperthyroidism. In rare cases of severe vasculitis a short course of high-dose glucocorticoid therapy may be helpful. PMID:3539299

  14. Adverse effects of cow's milk in infants.

    PubMed

    Ziegler, Ekhard E

    2007-01-01

    The feeding of cow's milk has adverse effects on iron nutrition in infants and young children. Several different mechanisms have been identified that may act synergistically. Probably most important is the low iron content of cow's milk. It makes it difficult for the infant to obtain the amounts of iron needed for growth. A second mechanism is the occult intestinal blood loss, which occurs in about 40% of normal infants during feeding of cow's milk. Loss of iron in the form of blood diminishes with age and ceases after 1 year of age. A third factor is calcium and casein provided by cow's milk in high amounts. Calcium and casein both inhibit the absorption of dietary nonheme iron. Infants fed cow's milk receive much more protein and minerals than they need. The excess has to be excreted in the urine. The high renal solute load leads to higher urine concentration during the feeding of cow's milk than during the feeding of breast milk or formula. When fluid intakes are low and/or when extrarenal water losses are high, the renal concentrating ability of infants may be insufficient for maintaining water balance in the face of high water use for excretion of the high renal solute. The resulting negative water balance, if prolonged, can lead to serious dehydration. There is strong epidemiological evidence that the feeding of cow's milk or formulas with similarly high potential renal solute load places infants at an increased risk of serious dehydration. The feeding of cow's milk to infants is undesirable because of cow's milk's propensity to lead to iron deficiency and because it unduly increases the risk of severe dehydration.

    The scientific knowledge about adverse effects of psychological therapies and how such effects should be detected is limited. It is possible that children and adolescents are particularly vulnerable and need specific support in order to express adverse effects. In this exploratory study, we used a qualitative approach to explore practitioners' experiences of this phenomenon. Fourteen practitioners providing psychological therapy within the Child and Adolescent Psychiatric Service were interviewed. Qualitative content analysis was applied to the data. Four overarching categories brought up by the practitioners were identified: vagueness of the concept (reflecting that the concept was novel and hard to define), psychotherapist-client interaction (encompassing aspects of the interaction possibly related to adverse effects), consequences for the young person (including a range of emotional, behavioural and social consequences) and family effects (e.g. professional complications and decreased autonomy for the parent). Professional discussions on these issues could improve psychological therapy for children and adolescents. Based on our findings and previous research, we propose three basic aspects to consider when adverse effects are detected and managed in this context: typology (form, severity and duration), aetiology (hypothesis about the causes) and perspective (adverse effects seen from the points of view of different interested parties).

  17. Equifinality, multifinality, and the rediscovery of the importance of early experiences: pathways from early adversity to psychiatric and (functional) somatic disorders.

    Most current mainstream research, diagnostic assessment, and treatment strategies focus on specific psychiatric disorders--on diagnoses that are based on manifest symptoms within a categorical, atheoretical approach. This disorder-centered approach has been antithetical to psychoanalytic views, which are fundamentally person centered, focusing on the dynamics of individual lives. Growing realization of the high comorbidity among psychiatric disorders has led to the need to include developmental considerations and hierarchical models in the classification and treatment of psychopathology. In addition, this realization has led to a renewed interest in the principles of equifinality and multifinality--that a given end state can be the result of different developmental paths and that similar developmental factors may lead to dissimilar outcomes. In this chapter these developments are illustrated by research on the impact of early adversity, a central domain in psychoanalytic thought. Findings from various strands of research in the neurosciences and genetic research, in particular, suggest that early adversity leads to vulnerability for a wide variety of both psychiatric and (functional) somatic disorders. These findings have contributed to the rediscovery of the importance of early experiences more generally and to the need for a broad developmental perspective. In this context, we also discuss the danger of reductionism associated with the growing influence and popularity of affective neuroscience and genetics as well as the vital role a psychoanalytic perspective might play in countering this reductionism by reestablishing the importance of meaning and meaning making in understanding and treating patients with a history of early adversity. In particular, we focus on the importance of narrative and mental representations in the development of the capacity for mentalization in these patients.

    There is a growing concern regarding the propensity of second generation antipsychotics (SGAs) to induce weight gain and metabolic adverse effects. Recent consensus guidelines have recommended assessment and monitoring procedures to appropriately detect and manage these adverse effects. This study addresses the appreciation and readiness of clinicians to implement management guidelines for these adverse effects. Respondents indicated awareness of the risks of treatment with SGAs. The extent of monitoring for metabolic adverse effects was low and inconsistent across measures and in frequency of evaluation. Ongoing efforts are needed to support and encourage change in clinician practice.

  19. The adverse health effects of chronic cannabis use.

    This paper summarizes the most probable of the adverse health effects of regular cannabis use sustained over years, as indicated by epidemiological studies that have established an association between cannabis use and adverse outcomes; ruled out reverse causation; and controlled for plausible alternative explanations. We have also focused on adverse outcomes for which there is good evidence of biological plausibility. The focus is on those adverse health effects of greatest potential public health significance--those that are most likely to occur and to affect a substantial proportion of regular cannabis users. These most probable adverse effects of regular use include a dependence syndrome, impaired respiratory function, cardiovascular disease, adverse effects on adolescent psychosocial development and mental health, and residual cognitive impairment.

    Misoprostol is a synthetic analogue of prostaglandin E1. It is used in gynaecology because of its properties of myometrium smooth muscle cells contraction and its effects on the cervix. Misoprostol oral bioavailability is low and several authors have assessed whether the administration by other routes increased its pharmacodynamic effects. This paper summarizes the pharmacokinetic studies after other routes of administration: vaginal, sublingual, buccal or rectal. It also provides an update on its adverse effects and teratogenic effects.

    2016-08-01

    We report on our research in using literature-based discovery (LBD) to provide pharmacological and/or pharmacogenomic explanations for reported adverse drug effects. The goal of LBD is to generate novel and potentially useful hypotheses by analyzing the scientific literature and optionally some additional resources. Our assumption is that drugs have effects on some genes or proteins and that these genes or proteins are associated with the observed adverse effects. Therefore, by using LBD we try to find genes or proteins that link the drugs with the reported adverse effects. These genes or proteins can be used to provide insight into the processes causing the adverse effects. Initial results show that our method has the potential to assist in explaining reported adverse drug effects.

    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. PMID:25061568

    The study was to assess the effectiveness of soft music for treatment of major depressive disorder inpatients in Kaohsiung City, Taiwan. A pretest-posttest with a two-group repeated measures design was used. Patients with major depressive disorder were recruited through referred by the psychiatric physicians. Subjects listened to their choice of music for 2 weeks. Depression was measured with the Zung's Depression Scale before the study and at two weekly posttests. Using repeated measures ANCOVA, music resulted in significantly better depressive scores, as well as significantly better subscores of depression compared with controls. Depression improved weekly, indicating a cumulative dose effect. The findings provide evidence for psychiatric nurses to use soft music as an empirically based intervention for depressed inpatients.

    2014-12-01

    Psychiatric disorders themselves--and not only the known psychotropic agents--lead to enhanced psychic and somatic morbidity, and not only as a so-called psychic reaction. Psychiatric disorders such as depression, anxiety disorders and schizophrenia are diseases with a high prevalence and incidence in most countries, and they are life-threatening because they induce--besides suicidality--also many somatic diseases such as coronary arte- riosclerotic syndrome and diabetes. As a result, they have an--often indirect--effect on mortality. In the future, studies should give greater attention to the underlying neurobiological mechanisms. True "psychosomatic medicine" consists of determining the combined biological effect of psychic and somatic factors and their interactions in greater detail.

    2012-11-01

    The topic of adverse effects of drugs is now receiving due attention in both the lay and medical communities. For drugs of the coagulation disorder class, such as anticoagulants and antiplatelet agents, the obvious adverse effects are bleeding from a dose too high and thrombosis from a dose too low. However, these drugs have other potential adverse effects that are not directly related to blood coagulation, yet cannot be dismissed due to their medical importance. There has been a recent advancement of several new drugs in this category and this number will soon grow as more drugs are reaching the end of their clinical trials. This article will discuss the nonhemostatic adverse effects of anticoagulants and antiplatelet drugs. As the adverse effects of bleeding and thrombosis will be excluded, this article will be in contrast to the typical discussions on the anticoagulant and antiplatelet drug classes.

    For over two decades, cannabis, commonly known as marijuana, has been the most widely used illicit drug by young people in high-income countries, and has recently become popular on a global scale. Epidemiological research during the past 10 years suggests that regular use of cannabis during adolescence and into adulthood can have adverse effects. Epidemiological, clinical, and laboratory studies have established an association between cannabis use and adverse outcomes. We focus on adverse health effects of greatest potential public health interest-that is, those that are most likely to occur and to affect a large number of cannabis users. The most probable adverse effects include a dependence syndrome, increased risk of motor vehicle crashes, impaired respiratory function, cardiovascular disease, and adverse effects of regular use on adolescent psychosocial development and mental health.

    Adverse childhood experiences are associated with an array of health, psychiatric, and behavioral problems including antisocial behavior. Criminologists have recently utilized adverse childhood experiences as an organizing research framework and shown that adverse childhood experiences are associated with delinquency, violence, and more chronic/severe criminal careers. However, much less is known about adverse childhood experiences vis-à-vis specific forms of crime and whether the effects vary across race and ethnicity. Using a sample of 2520 male confined juvenile delinquents, the current study used epidemiological tables of odds (both unadjusted and adjusted for onset, total adjudications, and total out of home placements) to evaluate the significance of the number of adverse childhood experiences on commitment for homicide, sexual assault, and serious persons/property offending. The effects of adverse childhood experiences vary considerably across racial and ethnic groups and across offense types. Adverse childhood experiences are strongly and positively associated with sexual offending, but negatively associated with homicide and serious person/property offending. Differential effects of adverse childhood experiences were also seen among African Americans, Hispanics, and whites. Suggestions for future research to clarify the mechanisms by which adverse childhood experiences manifest in specific forms of criminal behavior are offered. PMID:28327508

    Clinical descriptions of patients with Fetal Alcohol Syndrome (FAS) and Fetal Alcohol Effects (FAE) suggest major problems with adaptive behavior. Five operationally defined adverse outcomes and 18 associated risk/protective factors were examined using a Life History Interview with knowledgeable informants of 415 patients with FAS or FAE (median age 14 years, range 6-51; median IQ 86, range 29-126). Eighty percent of these patients were not raised by their biological mothers. For adolescents and adults, the life span prevalence was 61% for Disrupted School Experiences, 60% for Trouble with the Law, 50% for Confinement (in detention, jail, prison, or a psychiatric or alcohol/drug inpatient setting), 49% for Inappropriate Sexual Behaviors on repeated occasions, and 35% for Alcohol/Drug Problems. The odds of escaping these adverse life outcomes are increased 2- to 4-fold by receiving the diagnosis of FAS or FAE at an earlier age and by being reared in good stable environments.

    Clozapine (CLZ) is the drug of choice for the treatment of resistant schizophrenia; however, its suitable use is limited by the complex adverse effects’ profile. The best-described adverse effects in the literature are represented by agranulocytosis, myocarditis, sedation, weight gain, hypotension, and drooling; nevertheless, there are other known adverse effects that psychiatrists should readily recognize and manage. This review covers the “rare” and “very rare” known adverse effects of CLZ, which have been accurately described in literature. An extensive search on the basis of predefined criteria was made using CLZ and its combination with adverse effects as keywords in electronic databases. Data show the association between the use of CLZ and uncommon adverse effects, including ischemic colitis, paralytic ileus, hematemesis, gastroesophageal reflux disease, priapism, urinary incontinence, pityriasis rosea, intertriginous erythema, pulmonary thromboembolism, pseudo-pheochromocytoma, periorbital edema, and parotitis, which are influenced by other variables including age, early diagnosis, and previous/current pharmacological therapies. Some of these adverse effects, although unpredictable, are often manageable if promptly recognized and treated. Others are serious and potentially life-threatening. However, an adequate knowledge of the drug, clinical vigilance, and rapid intervention can drastically reduce the morbidity and mortality related to CLZ treatment. PMID:26273202

    Public health interventions may have a range of adverse effects. However, there is limited guidance as to how evaluations should address the possibility of adverse effects. This discussion paper briefly presents a framework for thinking about the potential harms of public health interventions, focusing on the following categories: direct harms; psychological harms; equity harms; group and social harms; and opportunity harms. We conclude that the possibility of adverse effects needs to be taken into account by those implementing and evaluating interventions, and requires a broad perspective on the potential impacts of public health strategies.

    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.

    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.

    2011-12-01

    BACKGROUND  Treatment of hepatitis C with peginterferon and ribavirin is associated with psychiatric side-effects, frequently necessitating dose reduction or therapy cessation. AIM  To assess the efficacy of prophylactic escitalopram to prevent psychiatric side-effects during peginterferon and ribavirin treatment in a randomised, double-blind, placebo-controlled trial. METHODS  Seventy-nine hepatitis C patients were treated with peginterferon and ribavirin. Patients received escitalopram (n = 40, 10 mg) or placebo (n = 39), which was initiated together with peginterferon and ribavirin. Primary outcomes were an increase of two points or more on the items reported sadness, inner tension and impaired concentration of the Montgomery-Asberg Depression Rating Scale, and hostile feelings of the Brief Anxiety Scale. Secondary outcome was the development of depression diagnosed by the Mini-International Neuropsychiatric Interview. Measurements were performed at baseline, week 4, 12 and 24 during anti-viral treatment, and 24 weeks thereafter. RESULTS  The incidence of psychiatric side-effects was significantly lower in patients treated with escitalopram compared with placebo for all primary and secondary outcomes, except for impaired concentration: reported sadness 27.5 vs. 48.7% (P = 0.052), inner tension 17.5 vs. 38.5% (P = 0.038), impaired concentration 55.0 vs. 66.7% (P = 0.288) and hostile feelings 22.5 vs. 43.6% (P = 0.046) (escitalopram vs. placebo, Chi-squared test). The sum scores of all four endpoints showed an overall beneficial effect of escitalopram (P = 0.009, Mann-Whitney U-test). Depression occurred in 12.5% of the patients in the escitalopram-group vs. 35.9% in the placebo-group (P = 0.015, Chi-squared test). CONCLUSIONS  Prophylactic treatment with escitalopram is effective in the prevention of psychiatric side-effects during interferon-based treatment of hepatitis C.

    2013-09-01

    The 7 July 2005 bombings in London caused heightened levels of distress among some in the general community. This distress was most notable in Muslims and members of ethnic minority groups. These effects were transient for most. An estimated 30% of those who were more affected by the attacks, including victims and witnesses, developed psychiatric disorders as a result. An outreach program was set up to screen those who were exposed to potentially traumatic events and to offer them evidence-based treatment. This article discusses what lessons might be learned from studies of the general community and the screen-and-treat approach.

    2003-01-01

    Several pharmacological treatments used in internal medicine can induce psychiatric side effects (PSEs) that mimic diagnoses seen in psychiatry. PSEs may occur upon withdrawal or intoxication, and also at usual therapeutic doses. Drugs that may lead to depressive, anxious, or psychotic syndromes include corticosteroids, isotretinoin, levo-dopar mefloquine, interferon-a, and anabolic steroids, as well as some over-the-counter medications. PSEs are often difficult to diagnose and can be very harmful to patients. PSEs are discussed in this review, as well as diagnostic clues to facilitate their identification. PMID:22034468

    The interest of psychiatric patients for complementary medicine, such as acupuncture, is stable, but effect studies in psychiatry remain scarce. In this pilot study, the effects of 3 months of acupuncture treatment on sleep were evaluated and compared between a group of patients with schizophrenia (n = 16) and a group with depression (n = 16). Healthy controls were included in order to establish reference values (n = 8). Patients with schizophrenia and depression were randomly assigned to either a waiting list or a treatment condition. The Pittsburgh Sleep Quality Inventory was completed before and after the acupuncture treatment (individualized and according to traditional Chinese medicine principles) or the waiting list condition. Both acupuncture groups showed significant lower scores on the sleep inventory, which was not the case for the waiting list condition. Moreover, it was found that the effectiveness of the acupuncture treatment was higher in the patients with schizophrenia than in the patients with depression. Acupuncture seems able to improve sleep in this convenient sample of patients with long-lasting psychiatric problems and may be a suitable and cost-effective add-on treatment for this group, particularly if conducted group-wise.

    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.

    Statin therapy is considered to be safe and rarely associated with serious adverse events. However, a significant proportion of patients on statin therapy show some degree of intolerance which can lead to decreased adherence to statin therapy. The authors summarize the symptoms, signs and frequencies of the most common statin-induced adverse effects and their most important risk factors including some single nucleotide polymorphisms and gene mutations. Also, they review the available approaches to detect and manage the statin-intolerant patients.

    The use of transmission precautions such as contact isolation in patients known to be colonised or infected with multidrug-resistant organisms is recommended in healthcare institutions. Although essential for infection control, contact isolation has recently been associated with adverse effects in patients. We undertook a systematic review to determine whether contact isolation leads to psychological or physical problems for patients. Studies were included if (1) hospitalised patients were placed under isolation precautions for an underlying medical indication, and (2) any adverse events related to the isolation were evaluated. We found 16 studies that reported data regarding the impact of isolation on patient mental well-being, patient satisfaction, patient safety or time spent by healthcare workers in direct patient care. The majority showed a negative impact on patient mental well-being and behaviour, including higher scores for depression, anxiety and anger among isolated patients. A few studies also found that healthcare workers spent less time with patients in isolation. Patient satisfaction was adversely affected by isolation if patients were kept uninformed of their healthcare. Patient safety was also negatively affected, leading to an eight-fold increase in adverse events related to supportive care failures. We found that contact isolation may negatively impact several dimensions of patient care. Well-validated tools are necessary to investigate these results further. Large studies examining a number of safety indicators to assess the adverse effects of isolation are needed. Patient education may be an important step to mitigate the adverse psychological effects of isolation and is recommended.

  13. Adverse effects of the radioprotector WR2721

    S-2-(3-Aminopropylamino)ethylphosphorothioic acid (WR2721) has radioprotective properties, but it is also toxic - in man it causes nausea and vomiting. Since radiation also causes nausea and vomiting it is important to know whether WR2721 would increase or decrease the likelihood of nausea and vomiting after radiation. This question was investigated in rats using the phenomenon of aversion to the taste of saccharin, which is readily inducible and is understood to be controlled in rats by the same pathways that control nausea and vomiting in man. The taste aversion was induced by giving 0.2 Gy /sup 60/Co ..gamma.. radiation 30 min after drinking 0.1% saccharin, or WR2721 immediately after the saccharin, or giving both radiation and WR2721. There were appropriate controls. In sham-irradiated rats, WR2721 (40 or 200 mg/kg, but not 8 mg/kg) produced a significant taste aversion. When WR2721 (40 or 200 mg/kg) was given immediately after the saccharin to irradiated rats it increased the taste aversion significantly, but it did not have any effect at 8 mg/kg. It was concluded that at doses which were optimal for radioprotection (approx.200 mg/kg) or lower, WR2721 increased in rats the taste aversion induced by radiation. By inference if conditioned taste aversion is an appropriate paradigm, WR2721 would increase nausea and vomiting in man induced by radiation.

  14. Adverse effects of thyroid hormone preparations and antithyroid drugs.

    Bartalena, L; Bogazzi, F; Martino, E

    1996-07-01

    Thyroid hormone preparations, especially thyroxine, are widely used either at replacement doses to correct hypothyroidism or at suppressive doses to abolish thyrotropin (thyroid-stimulating hormone) secretion in patients with differentiated thyroid carcinoma after total thyroidectomy or with diffuse/ nodular nontoxic goitre. In order to suppress thyrotropin secretion, it is necessary to administer slightly supraphysiological doses of thyroxine. Possible adverse effects of this therapy include cardiovascular changes (shortening of systolic time intervals, increased frequency of atrial premature beats and, possibly, left ventricular hypertrophy) and bone changes (reduced bone density and bone mass), but the risk of these adverse effects can be minimised by carefully monitoring serum free thyroxine and free liothyronine (triiodothyronine) measurements and adjusting the dosage accordingly. Thionamides [thiamazole (methimazole), carbimazole, propylthiouracil] are the most widely used antithyroid drugs. They are given for long periods of time and cause adverse effects in 3 to 5% of patients. In most cases, adverse effects are minor and transient (e.g. skin rash, itching, mild leucopenia). The most dangerous effect is agranulocytosis, which occurs in 0.1 to 0.5% of patients. This life-threatening condition can now be effectively treated by granulocyte colony-stimulating factor administration. Other major adverse effects (aplastic anaemia, thrombocytopenia, lupus erythematosus-like syndrome, vasculitis) are exceedingly rare.

    Although the use of cannabis shows no pronounced acute toxicity, acute psychological and psychomotor disturbances are observed occasionally after intake of single doses. Cannabis use can result in relevant impairment of driving ability. The risk is enhanced by concomitant use of alcohol. This augments the effect of cannabis significantly. After chronic use, significantly more psychotic symptoms become manifest, and there is a risk for developing psychological and physical dependence. Young age and pre-existing psychological disturbances increase the risk of these adverse effects. Chronic marijuana smoking is associated with increased toxicity and the risk of cancer of the respiratory tract. There is evidence of disturbance of the immune system and teratogenic effects of chronic cannabis use.

    Dey, Vivek Kumar

    2014-01-01

    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. PMID:25396124

  17. Adverse effects of oral antiviral therapy in chronic hepatitis B

    2017-01-01

    Oral nucleoside/nucleotide analogues (NAs) are currently the backbone of chronic hepatitis B (CHB) infection treatment. They are generally well-tolerated by patients and safe to use. To date, a significant number of patients have been treated with NAs. Safety data has accumulated over the years. The aim of this article is to review and update the adverse effects of oral NAs. NAs can cause class adverse effects (i.e., myopathy, neuropathy, lactic acidosis) and dissimilar adverse effects. All NAs carry a “Black Box” warning because of the potential risk for mitochondrial dysfunction. However, these adverse effects are rarely reported. The majority of cases are associated with lamivudine and telbivudine. Adefovir can lead to dose- and time-dependent nephrotoxicity, even at low doses. Tenofovir has significant renal and bone toxicity in patients with human immunodeficiency virus (HIV) infection. However, bone and renal toxicity in patients with CHB are not as prominent as in HIV infection. Entecavir and lamivudine are not generally associated with renal adverse events. Entecavir has been claimed to increase the risk of lactic acidosis in decompensated liver disease and high Model for End-Stage Liver Disease scores. However, current studies reported that entecavir could be safely used in decompensated cirrhosis. An increase in fetal adverse events has not been reported with lamivudine, telbivudine and tenofovir use in pregnant women, while there is no adequate data regarding entecavir and adefovir. Further long-term experience is required to highlight the adverse effects of NAs, especially in special patient populations, including pregnant women, elderly and patients with renal impairment.

    We present a case of adverse neurological effects of methylphenidate therapy for attention deficit and hyperactivity disorder (ADHD). A 7-year-old boy presented to the emergency department (ED) having developed ataxic gait, orofacial dyskinesias and choreoathetosis of the limbs. The results of all blood investigations, EEG and CT scan of the head were unremarkable. Subsequently, a detailed history revealed he was being treated for ADHD, being started on methylphenidate in the past 3 months. Discontinuation of methylphenidate led to significant and rapid amelioration of neurological adverse effects.

    The epidemiological data are limited for the spontaneous adverse drug reaction (ADR) reporting system in psychiatry and its comparison with intensive monitoring studies in terms of causative drugs, seriousness, preventability and drug interactions. This spontaneous ADR reporting study was carried out over a period of three years in the psychiatry department. We adopted WHO definition for an ADR, Naranjo's algorithm for causality, WHO-ADR terminology for the labeling of involved organ-system, International conference on harmonisation (ICH) E2A guidelines for seriousness, modified Schumock and Thornton's criteria for preventability and Medscape drug interaction checker for drug interactions. Two subgroup analyses were performed to find out the risk factors for the serious and preventable reactions. A total of 97 ADRs from 67 patients were included for analysis. The incidence of 'overall' and 'serious ADRs were 0.69% (95% CI: 0.54%, 0.88%) and 0.18% (95% CI: 0.12-0.29%), respectively. The females experienced more ADRs than males. The most commonly reported ADR, incriminated pharmacology group and drug, were extrapyramidal movement disorders (22.68%), atypical antipsychotics (35.62%) and escitalopram (13.91%), respectively. One out of five and one out three reactions were considered as 'serious' and 'preventable', respectively. The drug interactions contributed in 34.02% reactions. The factors significantly associated with 'serious' reactions were typical antipsychotics [OR: 5.47 (1.68, 17.87)], central and peripheral nervous system disorders [OR: 24.00 (5.12, 112.5)] and extrapyramidal reactions [OR: 14.03 (4.43, 44.43)]. The polypharmacy [OR: 5.85 (1.90, 18.03)] was significantly associated with 'preventable' reactions. The spontaneous reporting system is efficient to detect serious reactions and preventable reactions.

  1. Psychiatric side effects of mefloquine: applications to forensic psychiatry.

    Ritchie, Elspeth Cameron; Block, Jerald; Nevin, Remington Lee

    2013-01-01

    Mefloquine (previously marketed in the United States as Lariam®) is an antimalarial medication with potent psychotropic potential. Severe psychiatric side effects due to mefloquine intoxication are well documented, including anxiety, panic attacks, paranoia, persecutory delusions, dissociative psychosis, and anterograde amnesia. Exposure to the drug has been associated with acts of violence and suicide. In this article, we discuss the history of mefloquine use and describe plausible mechanisms of its psychotropic action. Mefloquine intoxication has not yet been successfully advanced in legal proceedings as a defense or as a mitigating factor, but it appears likely that it eventually will be. Considerations for the application of claims of mefloquine intoxication in forensic settings are discussed.

    The article critically reviews selected, clinically significant, adverse endocrine and metabolic effects associated with psychotropic drug treatments, including hyperprolactinaemia, hyponatraemia, diabetes insipidus, hypothyroidism, hyperparathyroidism, sexual dysfunction and virilization, weight loss, weight gain and metabolic syndrome (type 2 diabetes mellitus, dyslipidaemia and hypertension). Such effects are prevalent and complex, but can be managed clinically when recognized. They encourage continued critical assessment of benefits versus risks of psychotropic drugs and underscore the importance of close coordination of psychiatric and general medical care to improve long-term health of psychiatric patients. Options for management of hyperprolactinaemia include lowering doses, switching to agents such as aripiprazole, clozapine or quetiapine, managing associated osteoporosis, carefully considering the use of dopamine receptor agonists and ruling out stress, oral contraceptive use and hypothyroidism as contributing factors. Disorders of water homeostasis may include syndrome of inappropriate antidiuretic hormone (SIADH), managed by water restriction or slow replacement by hypertonic saline along with drug discontinuation. Safe management of diabetes insipidus, commonly associated with lithium, involves switching mood stabilizer and consideration of potassium-sparing diuretics. Clinical hypothyroidism may be a more useful marker than absolute cut-offs of hormone values, and may be associated with quetiapine, antidepressant and lithium use, and managed by thyroxine replacement. Hyper-parathyroidism requires comprehensive medical evaluation for occult tumours. Hypocalcaemia, along with multiple other psychiatric and medical causes, may result in decreased bone density and require evaluation and management. Strategies for reducing sexual dysfunction with psychotropics remain largely unsatisfactory. Finally, management strategies for obesity and metabolic syndrome

  12. Skin-lightening cosmetics: frequent, potentially severe adverse effects.

    PubMed

    2011-09-01

    Skin-lightening cosmetics are used by many women and men around the world. The products contain a variety of substances, which are often unknown to the users. Most of these products include topical corticosteroids, hydroquinone and mercury salts. Many other substances may be added. Several surveys and cohort studies, including several thousand individuals, have shown that regular application of skin-lightening cosmetics to large surface areas can have irreversible cutaneous adverse effects, such as patchy hyper- or hypopigmentation, skin atrophy, stretch marks and delayed wound healing, and can also mask or, on the contrary, promote or reactivate skin infections. Cases of skin cancer have been attributed to skin-lightening cosmetics. A Senegalese cohort study of 147 women showed a statistically significant increase in the risk of hypertension and diabetes linked to the use of skin-lightening agents. Other systemic adverse effects attributed to skin-lightening cosmetics include Cushing's syndrome, adrenal insufficiency, nephrotic syndrome, neurological disorders, and ocular disorders. Hypersensitivity reactions, including anaphylaxis, have also been attributed to these products. Many skin-lightening cosmetics contain substances that can harm the unborn child. For example, tretinoin is teratogenic while salicylic acid is feto-toxic. In practice, users are often unaware of the risk of severe adverse effects associated with skin-lightening cosmetics. Users should be informed of these adverse effects and encouraged to stop using these products, especially when skin disorders appear.

    SUMMARY 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

    2012-11-01

    Much literature has been written in the field of child psychiatry regarding the placebo as a tool to test drug efficacy in clinical trials, but quite little regarding the placebo effect itself or its clinical use in child psychiatry. In this article, we aim to critically review the literature regarding the placebo effect in children and adolescents with mental disorders, focusing especially on factors influencing the placebo effect and how they may influence the interpretation of clinical trials. The placebo effect seems to be more marked in children than adults, and particularly in children and adolescents with depression, although it is pervasive across ages and is present in non-psychiatric conditions as well. The use of a placebo in clinical trials as a comparator with drugs that have moderate efficacy at most makes it difficult to obtain positive results, and much effort is needed to design very high quality clinical trials that may overcome the limitations of using a placebo. In addition, the placebo effect across ages and clinical conditions must be tested directly (compared with no treatment whenever possible), in order to characterise which placebos work for what and to determine their use in clinical settings.

  16. Indoor air pollution: Acute adverse health effects and host susceptibility

    SciTech Connect

    Zummo, S.M.; Karol, M.H.

    1996-01-01

    Increased awareness of the poor quality of indoor air compared with outdoor air has resulted in a significant amount of research on the adverse health effects and mechanisms of action of indoor air pollutants. Common indoor air agents are identified, along with resultant adverse health effects, mechanisms of action, and likely susceptible populations. Indoor air pollutants range from biological agents (such as dust mites) to chemical irritants (such as nitrogen dioxide, carbon monoxide, sulfur dioxide, formaldehyde, and isocyanates). These agents may exert their effects through allergic as well as nonallergic mechanisms. While the public does not generally perceive poor indoor air quality as a significant health risk, increasing reports of illness related to indoor air and an expanding base of knowledge on the health effects of indoor air pollution are likely to continue pushing the issue to the forefront.

  17. Effect of wettability on adverse mobility immiscible floods

    1995-12-31

    Many immiscible displacements in reservoirs occur at adverse mobility. Effect of wettability on these displacements is not well understood and often ignored in reservoir simulation. Recent macroscopic theories of viscous fingering treat adverse immiscible flows similar to miscible flows, the mixing in the fingered region being controlled by a Todd-Longstaff-type functional form. The wettability of the medium is taken into account only through the use of appropriate relative permeabilities. The goal of this paper is to understand the macroscopic bypassing in adverse mobility immiscible floods. Immiscible displacements are conducted in a quarter 5-spot model in both drainage and imbibition modes at similar effective mobility ratios and viscous-to-gravity numbers. The level of bypassing and gravity override is visualized and measured. Tertiary water-alternating-gas (WAG) displacements are also conducted at various WAG ratios and viscosity ratios. Fractional flow analysis and numerical simulation are used to understand these displacements. Experiments show that macroscopic viscous fingering is present in adverse viscosity immiscible displacements where no saturation shock is expected from 1-D fractional flow theory. Bypassing due to both fingering and gravity override is higher in the drainage mode than in the imbibition mode, with other key parameters being the same. Optimum WAG ratio in water-wet rock is a function of oil/solvent viscosity ratio. The macroscopic flow theory needs to include capillarity and viscous fingering to match these experimental findings.

  20. Experiences from consumer reports on psychiatric adverse drug reactions with antidepressant medication: a qualitative study of reports to a consumer association

    PubMed Central

    2012-01-01

    Background The new European pharmacovigilance legislation has been suggested as marking the beginning of a new chapter in drug safety, making patients an important part of pharmacovigilance. In Sweden since 2008 it has been possible for consumers to report adverse drug reactions (ADRs) to the Medical Products Agency (MPA), and these reports are now understood as an increasingly valuable contribution in the monitoring of safety aspects in medicines. Already in 2002 it was possible to report experiences with medicines to the non-profit and independent organization Consumer Association for Medicines and Health (KILEN) through a web-based report form with an opportunity to describe ADR experiences in free text comments. The aim of this study was to qualitatively analyze the free text comments appended to consumer reports on antidepressant medication. Methods All reports of suspected adverse reactions regarding antidepressant medications submitted from January 2002 to April 2009 to KILEN’s Internet-based reporting system in Sweden were analyzed according to reported narrative experience(s). Content analysis was used to interpret the content of 181 reports with free text comments. Results Three main categories emerged from the analyzed data material: (1) Experiences of drug treatment with subcategories (a) Severe psychiatric adverse reactions, and (b) Discontinuation symptoms; (2) Lack of communication and (3) Trust and distrust. A majority of the reports to KILEN were from patients experiencing symptoms of mental disturbances (sometimes severe) affecting them in many different ways, especially during discontinuation. Several report included narratives of patients not receiving information of potential ADRs from their doctor, but also that there were no follow-ups of the treatment. Trust was highlighted as especially important and some patients reported losing confidence in their doctor when they were not believed about the suspected ADRs they experienced, making them

    The psychoactive effects of psychiatric medications have been obscured by the presumption that these medications have disease-specific actions. Exploiting the parallels with the psychoactive effects and uses of recreational substances helps to highlight the psychoactive properties of psychiatric medications and their impact on people with psychiatric problems. We discuss how psychoactive effects produced by different drugs prescribed in psychiatric practice might modify various disturbing and distressing symptoms, and we also consider the costs of these psychoactive effects on the mental well-being of the user. We examine the issue of dependence, and the need for support for people wishing to withdraw from psychiatric medication. We consider how the reality of psychoactive effects undermines the idea that psychiatric drugs work by targeting underlying disease processes, since psychoactive effects can themselves directly modify mental and behavioral symptoms and thus affect the results of placebo-controlled trials. These effects and their impact also raise questions about the validity and importance of modern diagnosis systems. Extensive research is needed to clarify the range of acute and longer-term mental, behavioral, and physical effects induced by psychiatric drugs, both during and after consumption and withdrawal, to enable users and prescribers to exploit their psychoactive effects judiciously in a safe and more informed manner.

    Consumption of energy drinks has been increasing dramatically in the last two decades, particularly amongst adolescents and young adults. Energy drinks are aggressively marketed with the claim that these products give an energy boost to improve physical and cognitive performance. However, studies supporting these claims are limited. In fact, several adverse health effects have been related to energy drink; this has raised the question of whether these beverages are safe. This review was carried out to identify and discuss the published articles that examined the beneficial and adverse health effects related to energy drink. It is concluded that although energy drink may have beneficial effects on physical performance, these products also have possible detrimental health consequences. Marketing of energy drinks should be limited or forbidden until independent research confirms their safety, particularly among adolescents. PMID:26715927

    Bisphosphonates are widely prescribed and highly effective at limiting the bone loss that occurs in many disorders characterized by increased osteoclast-mediated bone resorption, including senile osteoporosis in both men and women, glucocorticoid-associated osteoporosis, and malignancies metastatic to bone. Although they are generally well tolerated, potential adverse effects may limit bisphosphonate use in some patients. Optimal use of bisphosphonates for osteoporosis requires adequate calcium and vitamin D intake before and during therapy. The World Health Organization fracture risk assessment algorithm is currently available to determine absolute fracture risk in patients with low bone mass and is a useful tool for clinicians in identifying patients most likely to benefit from pharmacological intervention to limit fracture risk. This fracture risk estimate may facilitate shared decision making, especially when patients are wary of the rare but serious adverse effects that have recently been described for this class of drugs.

    Statin-associated muscular adverse effects cover a wide range of symptoms, including asymptomatic increase of creatine kinase serum activity and life-threatening rhabdomyolysis. Different underlying pathomechanisms have been proposed. However, a unifying concept of the pathogenesis of statin-related muscular adverse effects has not emerged so far. In this review, we attempt to categorize these mechanisms along three levels. Firstly, among pharmacokinetic factors, it has been shown for some statins that inhibition of cytochrome P450-mediated hepatic biotransformation and hepatic uptake by transporter proteins contribute to an increase of systemic statin concentrations. Secondly, at the myocyte membrane level, cell membrane uptake transporters affect intracellular statin concentrations. Thirdly, at the intracellular level, inhibition of the 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase results in decreased intracellular concentrations of downstream metabolites (e.g. selenoproteins, ubiquinone, cholesterol) and alteration of gene expression (e.g. ryanodine receptor 3, glycine amidinotransferase). We also review current recommendations for prescribers.

    Objectives. Studies have demonstrated the adverse effects of emergency department (ED) boarding. This study examines the impact of resource utilization, throughput, and financial impact for psychiatric patients awaiting inpatient placement. Methods. The authors retrospectively studied all psychiatric and non-psychiatric adult admissions in an Academic Medical Center ED (>68,000 adult visits) from January 2007-2008. The main outcomes were ED length of stay (LOS) and associated reimbursement. Results. 1,438 patients were consulted to psychiatry with 505 (35.1%) requiring inpatient psychiatric care management. The mean psychiatric patient age was 42.5 years (SD 13.1 years), with 2.7 times more women than men. ED LOS was significantly longer for psychiatric admissions (1089 min, CI (1039–1140) versus 340 min, CI (304–375); P < 0.001) when compared to non-psychiatric admissions. The financial impact of psychiatric boarding accounted for a direct loss of ($1,198) compared to non-psychiatric admissions. Factoring the loss of bed turnover for waiting patients and opportunity cost due to loss of those patients, psychiatric patient boarding cost the department $2,264 per patient. Conclusions. Psychiatric patients awaiting inpatient placement remain in the ED 3.2 times longer than non-psychiatric patients, preventing 2.2 bed turnovers (additional patients) per psychiatric patient, and decreasing financial revenue.

    Statins are a cornerstone of the pharmacologic treatment and prevention of atherosclerotic cardiovascular disease. Atherosclerotic disease is a predominant cause of mortality and morbidity worldwide. Statins are among the most commonly prescribed classes of medications, and their prescribing indications and target patient populations have been significantly expanded in the official guidelines recently published by the American and European expert panels. Adverse effects of statin pharmacotherapy, however, result in significant cost and morbidity and can lead to nonadherence and discontinuation of therapy. Statin-associated muscle symptoms occur in ~10% of patients on statins and constitute the most commonly reported adverse effect associated with statin pharmacotherapy. Substantial clinical and nonclinical research effort has been dedicated to determining whether genetics can provide meaningful insight regarding an individual patient’s risk of statin adverse effects. This contemporary review of the relevant clinical research on polymorphisms in several key genes that affect statin pharmacokinetics (eg, transporters and metabolizing enzymes), statin efficacy (eg, drug targets and pathways), and end-organ toxicity (eg, myopathy pathways) highlights several promising pharmacogenomic candidates. However, SLCO1B1 521C is currently the only clinically relevant pharmacogenetic test regarding statin toxicity, and its relevance is limited to simvastatin myopathy. PMID:27757045

    An increasing number of patients require long-term medication regimens at a young age, but the adverse effects of medications on male reproduction are often inadequately considered, recognized and investigated. Medications can affect male reproduction through central hormonal effects, direct gonadotoxic effects, effects on sperm function or on sexual function. For example, exogenous testosterone inhibits spermatogenesis through central suppression of the hypothalamic-pituitary-gonadal hormonal axis. 5α-reductase inhibitors can impair sexual function, decrease semen volume and negatively affect sperm parameters, depending on dose and treatment duration. α-Blockers might decrease seminal emission and cause retrograde ejaculation, depending on the receptor specificity and dose of the agent. Phosphodiesterase inhibitors seem to have variable effects based on the isoform inhibited and evidence is conflicting. Antihypertensive and psychotropic agents can affect sperm, sexual function and hormonal parameters. For antibiotics, the literature on effects on sperm and sperm function is limited and dated. Many chemotherapeutic agents have a direct gonadotoxic effect, depending on agents used, dosing and number of treatment cycles. Overall, many medications commonly used in urology can have effects on male fertility (mostly reversible) but conclusive evidence in humans is often limited. Men should be counselled appropriately about potential drug-related adverse effects on their fertility.

Cross-sectional study of a convenience sample of patients recruited from two San Diego Emergency Departments from January to December 2009. One-thousand-two-hundred-ninety-eight subjects participated of which 52.6% were male. Ethnicity: Caucasian 48.3%, African American 17%, Hispanic 18%, Other 16.7%. Age ranges: 18-29 years (38.4%), 30-54 years (49.6%) and greater than 55 years (12%). Reasons for use: 57% to "increase energy", 9.5% for studying/work projects, 2.4% while prolonged driving, improve sports performance 2%, with ethanol 6.3%, "other" reasons 22.1%. Adverse reactions reported by 33.5% (429) patients.

    The terms 'adverse drug effects' and 'adverse drug reactions' are commonly used interchangeably, but they have different implications. Adverse drug reactions arise when a compound (e.g. a drug or metabolite, a contaminant or adulterant) is distributed in the same place as a body tissue (e.g. a receptor, enzyme, or ion channel), and the encounter results in an adverse effect (a physiological or pathological change), which results in a clinically appreciable adverse reaction. Both the adverse effect and the adverse reaction have manifestations by which they can be recognized: adverse effects are usually detected by laboratory tests (e.g. biochemical, haematological, immunological, radiological, pathological) or by clinical investigations (e.g. endoscopy, cardiac catheterization), and adverse reactions by their clinical manifestations (symptoms and/or signs). This distinction suggests five scenarios: (i) adverse reactions can result directly from adverse effects; (ii) adverse effects may not lead to appreciable adverse reactions; (iii) adverse reactions can occur without preceding adverse effects; (iv) adverse effects and reactions may be dissociated; and (v) adverse effects and reactions can together constitute syndromes. Defining an adverse drug reaction as "an appreciably harmful or unpleasant reaction, resulting from an intervention related to the use of a medicinal product" suggests a definition of an adverse drug effect: "a potentially harmful effect resulting from an intervention related to the use of a medicinal product, which constitutes a hazard and may or may not be associated with a clinically appreciable adverse reaction and/or an abnormal laboratory test or clinical investigation, as a marker of an adverse reaction."

  12. Psychiatric sequelae of induced abortion.

    1984-03-01

    An attempt is made to identify and document the problems of comparative evaluation of the more recent studies of psychiatric morbidity after abortion and to determine the current consensus so that when the results of the joint RCGP/RCOG study of the sequelae of induced abortion become available they can be viewed in a more informed context. The legalization of abortion has provided more opportunities for studies of subsequent morbidity. New laws have contributed to the changing attitudes of society, and the increasing acceptability of the operation has probably influenced the occurrence of psychiatric sequelae. The complexity of measuring psychiatric sequelae is evident from the many terms used to describe symptomatology and behavioral patterns and from the number of assessment techniques involved. Numerous techniques have been used to quantify psychiatric sequelae. Several authors conclude that few psychiatric problems follow an induced abortion, but many studies were deficient in methodology, material, or length of follow-up. A British study in 1975 reported a favorable outcome for a "representative sample" of 50 National Health Service patients: 68% of these patients had an absence of or only mild feelings of guilt, loss, or self reproach and considered abortion as the best solution to their problem. The 32% who had an adverse outcome reported moderate to severe feelings of guilt, regret, loss, and self reproach, and there was evidence of mental illness. In most of these cases the adverse outcome was related to the patient's environment since the abortion. A follow-up study of 126 women, which compared the overall reaction to therapeutic abortion between women with a history of previous mild psychiatric illness and those without reported that a significantly different emotional reaction could not be demonstrated between the 2 groups.

    Four hundred seventy-nine drug abusing adolescent patients enrolled in seven Straight, Inc. Adolescent Drug-Abuse Treatment Programs in five geographic regions across the United States were studied to determine the severity and patterns of cocaine abuse. Of these, 341 admitted to cocaine use and became part of this survey. Cocaine use was categorized as heavy, intermediate, or light. Areas examined were the addictive spectrum, psychosocial dysfunction, and psychiatric symptoms. Intermediate and heavy users of cocaine abused significantly less marijuana and inhalants than light cocaine abusers. Heavy and intermediate users were more likely to use cocaine intravenously and to use crack. They developed tachyphylaxis more frequently, progressed to weekly use in less than 3 months more frequently, and became preoccupied with obtaining and using cocaine significantly more frequently. They used more sedative hypnotics to calm themselves and engaged in more criminal behavior, such as stealing from parents and stores and passing bad checks. They had more arrests for possession of drugs, stole more cars, sold more drugs, and were more likely to trade sexual favors to obtain the drug. Heavy and intermediate users were significantly more psychiatrically disturbed than light users, becoming more suspicious, nervous, aggressive, and demonstrating increased symptoms of fatigue, sleeplessness, decreased appetite, and increasing cocaine dysphoria. All of these symptoms could be mistaken for psychiatric disorders. This study suggests that cocaine is as addictive in adolescents as in adults; possibly more so. It also causes psychosocial dysfunction and psychiatric symptoms. Further research into cocaine addiction among adolescents is indicated.

    Anabolic-androgenic steroids (AAS) are synthetic drugs derived from testosterone. Illegally, these drugs are regularly self-administered by body builders and power lifters to enhance their sportive performance. Adverse side effects of AAS include sexual dysfunction, alterations of the cardiovascular system, psyche and behavior, and liver toxicity. However, severe side effects appear only following prolonged use of AAS at high dose and their occurrence is limited. Occasionally, AAS abuse may be linked to certain social and psychological traits of the user, like low self-esteem, low self-confidence, suffered hostility, childhood conduct disorder, and tendency to high-risk behavior. The overwhelming stereotype about AAS is that these compounds cause aggressive behavior in males. However, the underlying personality traits of a specific subgroup of the AAS abusers, who show aggression and hostility, may be relevant, as well. Use of AAS in combination with alcohol largely increases the risk of violence and aggression. The dependence liability of AAS is very low, and withdrawal effects are relatively mild. Based on the scores for acute and chronic adverse health effects, the prevalence of use, social harm and criminality, AAS were ranked among 19 illicit drugs as a group of drugs with a relatively low harm.

    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.

    Long-term remission of HIV-1 disease can be readily achieved by combinations of antiretroviral agents. The suppression of plasma viral loads to less than the limit of quantification of the most sensitive commercially available assays (i.e., less than 50 copies/mL) and the coincident improvement in CD4 T cell counts is associated with resolution of established opportunistic infections and a decrease in the risk of new opportunistic infections. However, prolonged treatment with combination regimens can be difficult to sustain because of problems with adherence and toxic effects. All antiretroviral drugs can have both short-term and long-term adverse events. The risk of specific side effects varies from drug to drug, from drug class to drug class, and from patient to patient. A better understanding of the adverse effects of antiretroviral agents is of interest not only for HIV specialists as they try to optimize therapy, but also for other physicians who care for HIV-positive patients.

    This study examined effects of type of and cumulative burden of childhood adversities on bullying and cruelty to animals in the United States. Data were derived from Waves I and II of the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of U.S. adults. Structured psychiatric interviews were completed by trained lay interviewers between 2001-2002 and 2003-2004. Although the effects of childhood adversity diminished with the inclusion of confounding variables, several adversities remained significant. For bullying, these included being made to do chores that were too difficult or dangerous, threatening to hit or throw something, pushing, shoving, slapping, or hitting, and hitting that left bruises, marks, or injuries. With respect to cruelty to animals, swearing and saying hurtful things, having a parent or other adult living within the home that went to jail or prison, and adult/other person fondling/touching in a sexual way were significant. The final models indicated that the cumulative burden of childhood adversities had strong effects on the increased likelihood of bullying behavior but not cruelty to animals.

    BPA is a ubiquitous environmental contaminant, resulting mainly from manufacturing,use or disposal of plastics of which it is a component, and the degradation of industrial plastic-related wastes. Growing evidence from research on laboratory animals, wildlife, and humans supports the view that BPA produces an endocrine disrupting effect and adversely affects male reproductive function. To better understand the adverse effects caused by exposure to BPA, we performed an up-to-date literature review on the topic, with particular emphasis on in utero exposure, and associated effects on spermatogenesis, steroidogenesis, and accessory organs.BPA studies on experimental animals show that effects are generally more detrimental during in utero exposure, a critical developmental stage for the embryo. BPA has been found to produce several defects in the embryo, such as feminization of male fetuses, atrophy of the testes and epididymides, increased prostate size, shortening of AGD, disruption of BTB, and alteration of adult sperm parameters (e.g.,sperm count, motility, and density). BPA also affects embryo thyroid development.During the postnatal and pubertal periods and adulthood, BPA affects the hypothalamic-pituitary-testicular axis by modulating hormone (e.g., LH and FSH,androgen and estrogen) synthesis, expression and function of respective receptors(ER, AR). These effects alter sperm parameters. BPA also induces oxidative stress in the testis and epididymis, by inhibiting antioxidant enzymes and stimulating lipid peroxidation. This suggests that employing antioxidants may be a promising strategy to relieve BPA-induced disturbances.Epidemiological studies have also provided data indicating that BPA alters male reproductive function in humans. These investigations revealed that men occupationally exposed to BPA had high blood/urinary BPA levels, and abnormal semen parameters. BPA-exposed men also showed reduced libido and erectile ejaculatory difficulties; moreover, the

    With fewer newborns and people living longer, older people are making up an increasing fraction of the total population. Epidemiological evidence shows that older-age-related health problems affect a wide and expanding proportion of the world population. One of the major epidemiological trends of this century is the rise of chronic diseases that affect more elderly than younger people. A total of 3.7 million premature deaths worldwide in 2012 are attributable to outdoor air pollution; the susceptibility to adverse effects of air pollution is expected to differ widely between people and within the same person, and also over time. Frailty history, a measure of multi-system decline, modifies cumulative associations between air pollution and lung function. Moreover, pre-existing diseases may determine susceptibility. In the elderly, due to comorbidity, exposure to air pollutants may even be fatal. Rapid and not-well-planned urbanization is associated with high level of ambient air pollution, mainly caused by vehicular exhausts. In general, there is sufficient evidence of the adverse effects related to short-term exposure, while fewer studies have addressed the longer-term health effects. Increased pollution exposures have been associated with increased mortality, hospital admissions/emergency-room visits, mainly due to exacerbations of chronic diseases or to respiratory tract infections (e.g., pneumonia). These effects may also be modulated by ambient temperature and many studies show that the elderly are mostly vulnerable to heat waves. The association between heat and mortality in the elderly is well-documented, while less is known regarding the associations with hospital admissions. Chronic exposure to elevated levels of air pollution has been related to the incidence of chronic obstructive pulmonary disease (COPD), chronic bronchitis (CB), asthma, and emphysema.

    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.

    In addition to the person-environment fit model (J. R. French, R. D. Caplan, & R. V. Harrison, 1982) and the demand-control model (R. A. Karasek & T. Theorell, 1990), a third theoretical concept is proposed to assess adverse health effects of stressful experience at work: the effort-reward imbalance model. The focus of this model is on reciprocity of exchange in occupational life where high-cost/low-gain conditions are considered particularly stressful. Variables measuring low reward in terms of low status control (e.g., lack of promotion prospects, job insecurity) in association with high extrinsic (e.g., work pressure) or intrinsic (personal coping pattern, e.g., high need for control) effort independently predict new cardiovascular events in a prospective study on blue-collar men. Furthermore, these variables partly explain prevalence of cardiovascular risk factors (hypertension, atherogenic lipids) in 2 independent studies. Studying adverse health effects of high-effort/low-reward conditions seems well justified, especially in view of recent developments of the labor market.

    Self-medication means resorting to one or more drugs in order to treat oneself without the help of a doctor. This phenomenon is developing fast. In this review, we will discuss the main definitions of self-medication; we will then present a few important characteristics of this therapeutic practice: prevalence, reasons, populations involved and drugs used. Whilst the theoretical risks of self-medication have been abundantly discussed in the literature (adverse effects, interactions, product, dosage or treatment duration errors, difficulty in self-diagnosis, risk of addiction or abuse…), there is in fact very little detailed pharmacovigilance data concerning the characteristics and the consequences of this usage in real life. This study therefore describes the all too rare data that is available: patients, clinical characteristics, "seriousness" and drugs involved in the adverse effects of self-medication. It also discusses leads to be followed in order to minimize medication risks, which are obviously not well known and clearly not sufficiently notified.

    Ondansetron is a serotonin receptor antagonist which has been used frequently to reduce the incidence of post-operative nausea and vomiting in laparoscopic surgery. It has become very popular drug for the prevention of post-operative nausea and vomiting due to its superiority in-terms of efficacy as well as lack of side effects and drug interactions. Although cardiovascular adverse effects of this drug are rare, we found a case of symptomatic sinus bradycardia in a 43-year-old female patient, going for laparoscopic cholecystectomy, who developed the same after she was given intravenous ondansetron in operation theater during premedication. Hence, we report this case, as the rare possibility of encountering bradycardia effect after intravenous administration of ondansetron should be born in mind. PMID:21655029

    The question of whether heated fats in the diet may be detrimental to health is nowadays of the upmost concern, but finding an answer is not easy and requires careful consideration of different aspects of lipid oxidation. This review is divided into two sections. The first part deals with the nature of the new compounds formed at high temperature in the frying process as well as their occurrence in the diet while the second part focuses on their possible nutritional and physiological effects. Oxidation products present in abused frying fats and oils are the compounds most suspected of impairing the nutritional properties of the oils or involving adverse physiological effects. The recent studies on their health implications include those related to their fate and those focused on their effects in metabolic pathways and the most prevalent diseases.

    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. In conclusion, decreased fertility may be a serious problem Botox® injections could cause. - Highlights: • Botox® injections are the trend nowadays, for both medical and non-medical uses. • They were recently suggested for cryptorchidism and

  8. Denosumab. Limited efficacy in fracture prevention, too many adverse effects.

    PubMed

    2011-06-01

    The standard drug for postmenopausal osteoporotic women with a high risk of fracture is alendronic acid, used in conjunction with non-drug measures. There are no drugs with demonstrated efficacy on the risk of fracture in castrated men with prostate cancer. Denosumab, a monoclonal antibody that inhibits a cytokine acting mainly on bone cells and lymphocytes, has been authorised in the European Union for use in both these settings. There are no trials comparing denosumab versus alendronic acid for symptomatic fracture prevention. In two trials involving 1189 and 504 women, the incidence of clinical fractures, recorded as simple adverse effects, did not differ significantly between the groups. In a placebo-controlled trial in about 7900 elderly osteoporotic women, denosumab significantly reduced the incidence of symptomatic vertebral fractures (0.8% versus 2.6% after 3 years) and hip fractures (0.7% versus 1.2%). An indirect comparison, providing weak evidence, suggests that denosumab is less effective than alendronic acid. In a placebo-controlled trial in 1468 castrated men with prostate cancer, denosumab did not reduce the incidence of symptomatic fractures after 3 years. Only the incidence of vertebral fractures, detected on routine radiographs, showed a statistically significant decline (1.5% versus 3.5%). Denosumab has numerous adverse effects. In placebo-controlled trials, this monoclonal antibody was associated with a higher incidence of deep-seated infections such as endocarditis, cancer, and skin rash. More data are needed on the risk of pancreatitis, long-term bone disorders (atypical fractures, delayed fracture healing, osteonecrosis of the jaw), hypocalcaemia and cataracts, all of which were reported in clinical trials. In practice, denosumab is not sufficiently effective to outweigh its established and potential risks in postmenopausal osteoporotic women or in castrated men with prostate cancer.

    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.

  10. Does Cannabidiol Protect Against Adverse Psychological Effects of THC?

    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.

    The growing use and legalization of cannabis are leading to increased exposures across all age groups, including in adolescence. The touting of its medicinal values stems from anecdotal reports related to treatment of a broad range of illnesses including epilepsy, multiple sclerosis, muscle spasms, arthritis, obesity, cancer, Alzheimer disease, Parkinson disease, post-traumatic stress, inflammatory bowel disease, and anxiety. However, anecdotal data and the high level of interest in this treatment must not obscure objective assessments of any potential and realized short- and long-term adverse effects of cannabis, particularly with respect to age of onset and chronicity of exposure. This critical review focuses on evidence-based research designed to assess both therapeutic benefits and harmful effects of cannabis exposure and is combined with an illustration of the neuropathologic findings in a fatal case of cannabis-induced psychosis. The literature and reported case provide strong evidence that chronic cannabis abuse causes cognitive impairment and damages the brain, particularly white matter, where cannabinoid 1 receptors abound. Contrary to popular perception, there are few objective data supporting preferential use of cannabis over conventional therapy for restoration of central nervous system structure and function in disease states such as multiple sclerosis, epilepsy, or schizophrenia. Additional research is needed to determine if subsets of individuals with various neurological and psychiatric diseases derive therapeutic benefits from cannabis.

    Objective We investigated the performance of North Korean refugees on attention tasks, and the relationship between that performance and psychiatric symptoms. Methods Sustained and divided attention was assessed using the computerized Comprehensive Attention Test in North Korean refugees and in South Koreans. All participants also completed the Beck Depression Inventory, the Beck Anxiety Inventory, the Impact of Event Scale-Revised and the Dissociative Experiences Scale-II (DES-II). Results The North Korean refugees showed slower reaction times (RTs) on the visual sustained attention task compared to the South Koreans after controlling for age and sex. North Korean refugees had a greater number of omission errors (OEs) on the divided attention task and a higher standard deviation (SD) of RT. Total DES-II scores of the North Korean refugees were associated with the number of OEs and the SD of RT on the sustained attention task, and with the number of OEs on the divided attention task. Conclusion North Korean refugees showed poorer performance on computerized attention tasks. In addition, attention deficit among North Korean refugees was associated with their dissociative experiences. Our results suggest that refugees may have attention deficits, which may be related to their psychiatric symptoms, particularly dissociation. PMID:27757125

    2012-01-01

    Exposure to ambient air pollution is a serious and common public health concern associated with growing morbidity and mortality worldwide. In the last decades, the adverse effects of air pollution on the pulmonary and cardiovascular systems have been well established in a series of major epidemiological and observational studies. In the recent past, air pollution has also been associated with diseases of the central nervous system (CNS), including stroke, Alzheimer's disease, Parkinson's disease, and neurodevelopmental disorders. It has been demonstrated that various components of air pollution, such as nanosized particles, can easily translocate to the CNS where they can activate innate immune responses. Furthermore, systemic inflammation arising from the pulmonary or cardiovascular system can affect CNS health. Despite intense studies on the health effects of ambient air pollution, the underlying molecular mechanisms of susceptibility and disease remain largely elusive. However, emerging evidence suggests that air pollution-induced neuroinflammation, oxidative stress, microglial activation, cerebrovascular dysfunction, and alterations in the blood-brain barrier contribute to CNS pathology. A better understanding of the mediators and mechanisms will enable the development of new strategies to protect individuals at risk and to reduce detrimental effects of air pollution on the nervous system and mental health.

    Long-term glucocorticoid treatment is associated with numerous adverse outcomes, including weight gain, insulin resistance, and diabetes; however, the pathogenesis of these side effects remains obscure. Glucocorticoids also suppress osteoblast function, including osteocalcin synthesis. Osteocalcin is an osteoblast-specific peptide that is reported to be involved in normal murine fuel metabolism. We now demonstrate that osteoblasts play a pivotal role in the pathogenesis of glucocorticoid-induced dysmetabolism. Osteoblast-targeted disruption of glucocorticoid signaling significantly attenuated the suppression of osteocalcin synthesis and prevented the development of insulin resistance, glucose intolerance, and abnormal weight gain in corticosterone-treated mice. Nearly identical effects were observed in glucocorticoid-treated animals following heterotopic (hepatic) expression of both carboxylated and uncarboxylated osteocalcin through gene therapy, which additionally led to a reduction in hepatic lipid deposition and improved phosphorylation of the insulin receptor. These data suggest that the effects of exogenous high-dose glucocorticoids on insulin target tissues and systemic energy metabolism are mediated, at least in part, through the skeleton.

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

    PubMed

    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.

    Few well-controlled studies have considered neurofeedback treatment in adult psychiatric patients. In this regard, the present study investigates the characteristics and effects of neurofeedback on adult psychiatric patients in a naturalistic setting. A total of 77 adult patients with psychiatric disorders participated in this study. Demographic data and neurofeedback states were retrospectively analyzed, and the effects of neurofeedback were evaluated using clinical global impression (CGI) and subjective self-rating scales. Depressive disorders were the most common psychiatric disorders (19; 24.7 %), followed by anxiety disorders (18; 23.4 %). A total of 69 patients (89.6 %) took medicine, and the average frequency of neurofeedback was 17.39 ± 16.64. Neurofeedback was applied to a total of 39 patients (50.6 %) more than 10 times, and 48 patients (62.3 %) received both β/SMR and α/θ training. The discontinuation rate was 33.8 % (26 patients). There was significant difference between pretreatment and posttreatment CGI scores (<.001), and the self-rating scale also showed significant differences in depressive symptoms, anxiety, and inattention (<.001). This is a naturalistic study in a clinical setting, and has several limitations, including the absence of a control group and a heterogenous sample. Despite these limitations, the study demonstrates the potential of neurofeedback as an effective complimentary treatment for adult patients with psychiatric disorders.

  18. The cost-effectiveness of psychotherapy for the major psychiatric diagnoses.

    Psychotherapy is an effective and often highly cost-effective medical intervention for many serious psychiatric conditions. Psychotherapy can also lead to savings in other medical and societal costs. It is at times the firstline and most important treatment and at other times augments the efficacy of psychotropic medication. Many patients are in need of more prolonged and intensive psychotherapy, including those with personality disorders and those with chronic complex psychiatric conditions often with severe anxiety and depression. Many patients with serious and complex psychiatric illness have experienced severe early life trauma in an atmosphere in which family members or caretakers themselves have serious psychiatric disorders. Children and adolescents with learning disabilities and those with severe psychiatric disorders can also require more than brief treatment. Other diagnostic groups for whom psychotherapy is effective and cost-effective include patients with schizophrenia, anxiety disorders (including posttraumatic stress disorder), depression, and substance abuse. In addition, psychotherapy for the medically ill with concomitant psychiatric illness often lowers medical costs, improves recovery from medical illness, and at times even prolongs life compared to similar patients not given psychotherapy. While "cost-effective" treatments can yield savings in healthcare costs, disability claims, and other societal costs, "cost-effective" by no means translates to "cheap" but instead describes treatments that are clinically effective and provided at a cost that is considered reasonable given the benefit they provide, even if the treatments increase direct expenses. In the current insurance climate in which Mental Health Parity is the law, insurers nonetheless often use their own non-research and non-clinically based medical necessity guidelines to subvert it and limit access to appropriate psychotherapeutic treatments.

    The goals of epilepsy therapy are to achieve seizure freedom while minimizing adverse effects of treatment. However, producing seizure-freedom is often overemphasized, at the expense of inducing adverse effects of treatment. All antiepileptic drugs (AEDs) have the potential to cause dose-related, "neurotoxic" adverse effects (i.e., drowsiness, fatigue, dizziness, blurry vision, and incoordination). Such adverse effects are common, especially when initiating AED therapy and with polytherapy. Dose-related adverse effects may be obviated in most patients by dose reduction of monotherapy, reduction or elimination of polytherapy, or substituting for a better tolerated AED. Additionally, all older and several newer AEDs have idiosyncratic adverse effects which usually require withdrawal in an affected patient, including serious rash (i.e., Stevens-Johnson Syndrome, toxic epidermal necrolysis), hematologic dyscrasias, hepatotoxicity, teratogenesis in women of child bearing potential, bone density loss, neuropathy, and severe gingival hyperplasia. Unfortunately, occurrence of idiosyncratic AED adverse effects cannot be predicted or, in most cases, prevented in susceptible patients. This article reviews a practical approach for the definition and identification of adverse effects of epilepsy therapies, and reviews the literature demonstrating that adverse effects result in detrimental quality of life in epilepsy patients. Strategies for minimizing AED adverse effects by reduction or elimination of AED polytherapy, appropriately employing drug-sparing therapies, and optimally administering AEDs are outlined, including tenets of AED selection, titration, therapeutic AED laboratory monitoring, and avoidance of chronic idiosyncratic adverse effects.

    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.

  1. Shocking Results on the Adverse Effects of CO2 Exposures

    2012-01-01

    Carbon dioxide (CO2) is released in large quantities from humans while they live and work in spacecraft or work outside the spacecraft during extravehicular activity (EVA). Removal of this anthropogenic pollutant requires major resources, and these resources increase dramatically as the levels of CO2 set to protect human health and performance are reduced. The current Spacecraft Maximum Allowable Concentration of CO2 aboard the ISS is 0.7% or 5.3 mmHg; however, according to Chits (mission action requests), NASA and its international partners have agreed to control CO2 levels to less than 4 mmHg. In the meantime, retrospective investigations attempting to associate crew symptoms with elevated CO2 levels over the life if the International Space Station (ISS) are underway to determine if this level is sufficient to protect against health and performance decrements. Anecdotal reports suggest that crewmembers are not able to perform complex tasks as readily in spaceflight as they were able during ground-based training. While physiological effects of CO2 have been studied for many decades, it is only recently that the effects of CO2 on higher reasoning capabilities have been studied. The initial results are shocking. For example, one study published in the respected journal Environmental Health Perspectives showed obvious adverse effects of CO2 exposures on higher reasoning at 1.9 mmHg. The implications and limitations of this study are paramount in determining future CO2 SMACs for human spaceflight, both aboard the ISS and in exploration-class missions.

    2015-02-01

    Research and drug developments fostered under orphan drug product development programs have greatly assisted the introduction of efficient and safe enzyme-based therapies for a range of rare disorders. The introduction and regulatory approval of 20 different recombinant enzymes has enabled, often for the first time, effective enzyme-replacement therapy for some lysosomal storage disorders, including Gaucher (imiglucerase, taliglucerase, and velaglucerase), Fabry (agalsidase alfa and beta), and Pompe (alglucosidase alfa) diseases and mucopolysaccharidoses I (laronidase), II (idursulfase), IVA (elosulfase), and VI (galsulfase). Approved recombinant enzymes are also now used as therapy for myocardial infarction (alteplase, reteplase, and tenecteplase), cystic fibrosis (dornase alfa), chronic gout (pegloticase), tumor lysis syndrome (rasburicase), leukemia (L-asparaginase), some collagen-based disorders such as Dupuytren's contracture (collagenase), severe combined immunodeficiency disease (pegademase bovine), detoxification of methotrexate (glucarpidase), and vitreomacular adhesion (ocriplasmin). The development of these efficacious and safe enzyme-based therapies has occurred hand in hand with some remarkable advances in the preparation of the often specifically designed recombinant enzymes; the manufacturing expertise necessary for commercial production; our understanding of underlying mechanisms operative in the different diseases; and the mechanisms of action of the relevant recombinant enzymes. Together with information on these mechanisms, safety findings recorded so far on the various adverse events and problems of immunogenicity of the recombinant enzymes used for therapy are presented.

    The present study was undertaken to evaluate the oxidative damage, biochemical and histopathological alterations in sucking rats whose mothers were exposed to the insecticide chlorpyrifos (CPF). Dams were administered CPF, via oral route. Doses equalled 0.01 mg kg(-1) body weight (b.wt.; acceptable daily intake, ADI), 1.00 mg kg(-1) b.wt. (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.

  5. 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.

    The study was set up to evaluate the impact of the total drug load of antiepileptic pharmacotherapy on cognition. Retrospective analyses were based on 834 patients with epilepsy who underwent a brief routine assessment of executive function and verbal memory (EpiTrack Plus) at our department. The total drug load was quantified in two ways: (1) number of concurrent antiepileptic drugs (AEDs) and (2) total drug load according to the defined daily dose (DDD) provided by the World Health Organization. The cognitive measures showed higher inverse correlations with the number of AEDs (executive function: r=-0.35, p<0.001; memory: r=-0.22, p<0.001) than with the total DDD (executive function: r=-0.27, p<0.001; memory: r=-0.17, p<0.001). Reanalysis with statistical control for disease severity hardly changed the aforementioned results. With each additional drug in polytherapy, we observed a significantly lower performance in executive function. In this regard an additional explorative approach revealed that regimens combining AEDs with favorable cognitive profiles were associated with higher cognitive performance. Correlations between indicators of disease severity and drug load indices were low: altogether explaining only up to 9% of the observed variance in drug load. The findings demonstrate a considerable adverse effect of a higher drug load on cognition, especially on executive functions. Simply counting the number of drugs may be sufficient as a rough estimate of the risk of side effects. However, the combination of AEDs with favorable cognitive profiles may attenuate the negative effect of the total drug load.

  7. Ropinirole: new indication. Restless legs: disproportionate adverse effects.

    (1) The restless legs syndrome consists of unpleasant sensory and motor symptoms of varying intensity in the lower limbs. Symptoms occur at rest, seated or lying down, are more intense in the evening and at night, and are relieved by moving the limb. This syndrome does not cause serious physical complications. When sleep disturbances occur, non drug methods should be tried first. (2) Ropinirole is a dopaminergic agonist initially marketed for the treatment of Parkinson's disease. It is the first drug to be approved for restless legs syndrome in France. (3) Three double-blind randomised placebo-controlled trials with similar designs showed minimal differences on a composite rating scale. After 12 weeks of treatment, ropinirole led to an improvement of about 3 points on a 40-point scale compared with placebo. (4) A 12-week double-blind randomised controlled trial and including patients who had "responded" to ropinirole showed a lower relapse rate in the group that continued to use ropinirole (32.6%) instead of switching to placebo (57.8%). However, we do not know if this was because of continued drug efficacy or a rebound effect in the placebo group. (5) The adverse effects of ropinirole in patients with restless legs syndrome had already been observed in the treatment of Parkinson's disease, and included nausea, vomiting, drowsiness, a sudden urge to sleep, syncope, hypotension, and hallucinations. (6) An increase in the severity of restless legs symptoms, typically seen with levodopa, was not evaluated in clinical trials of ropinirole. Some cases have nevertheless been reported. They describe the appearance of symptoms increasingly early in the evening, then in the afternoon, or as a rebound effect in the morning or the latter part of the night. Their intensity increases and can affect other parts of the body. (7) In practice, ropinirole has a negative risk-benefit balance in restless legs syndrome, which is a minor health disorder.

    Cognitive deficits in old-age depression vary as a function of multiple factors; one rarely examined factor is long-term psychiatric history. We investigated effects of psychiatric history on cognitive performance in old-age depression and in remitted persons. In the population-based Swedish National Study on Aging and Care in Kungsholmen study, older persons (≥60 years) without dementia were tested with a cognitive battery and matched to the Swedish National Inpatient Register (starting 1969). Participants were grouped according to current depression status and psychiatric history and compared to healthy controls (n = 96). Group differences were observed for processing speed, attention, executive functions, and verbal fluency. Persons with depression and psychiatric inpatient history (n = 20) and late-onset depression (n = 49) performed at the lowest levels, whereas cognitive performance in persons with self-reported recurrent unipolar depression (n = 52) was intermediate. Remitted persons with inpatient history of unipolar depression (n = 38) exhibited no cognitive deficits. Heart disease burden, physical inactivity, and cumulative inpatient days modulated the observed group differences in cognitive performance. Among currently depressed persons, those with inpatient history, and late onset performed at the lowest levels. Importantly, remitted persons showed no cognitive deficits, possibly reflecting the extended time since the last admission (m = 15.6 years). Thus, the present data suggest that cognitive deficits in unipolar depression may be more state- than trait-related. Information on profiles of cognitive performance, psychiatric history, and health behaviors may be useful in tailoring individualized treatment. PMID:26175699

    It is a popularly held belief that psychiatric behavior worsens during a full moon. Research in this area has yielded mixed results. Records from Naval Medical Center San Diego for 1993-2001 were examined to see whether there were higher rates of psychiatric admission associated with particular phases of the moon. Records from 8,473 admissions revealed that there were no more admission on days with a full moon, a new moon, any quarter of the moon, a waxing moon, or a waning moon. This held true for psychiatric patients as a whole, as well as for individuals with particular diagnoses, such as those with a mood disorder or psychotic disorder. Records from 1,909 emergency psychiatric evaluations that occurred between 2002 and 2003 were also examined to see whether a higher percentage of patients might present, but not require hospitalization, during a particular phase of the moon. Once again, no significant effect was found. In summary, lunar phase was not associated in any significant way with psychiatric admissions or emergency presentation.

  10. Ziconotide: new drug. Limited analgesic efficacy, too many adverse effects.

    2008-10-01

    (1) When oral morphine does not relieve severe pain and when there is no specific treatment for the underlying cause, the first option is to try subcutaneous or intravenous administration. If this standard treatment fails or is poorly tolerated, intrathecal injection is usually preferred as the direct route to the central nervous system. However, one-quarter to one-half of patients still do not achieve adequate pain relief, and adverse effects are relatively frequent; (2) Ziconotide is not an opiate and is not related to the usual classes of drugs that interfere with nervous transmission in the posterior horn of the spinal cord. Marketing authorization has been granted for "severe, chronic pain in patients who require intrathecal analgesia". The Summary of Product Characteristics (SPC) recommends continuous infusion via an intrathecal catheter connected to a pump; (3) Clinical evaluation of ziconotide does not include any trials versus morphine in patients with nociceptive pain, or any trials versus tricyclic or antiepileptic drugs in patients with neurogenic pain; (4) In a trial in 220 patients in whom systemic morphine had failed, the mean pain score on a 100-mm visual analogue scale was 69.8 mm after three weeks on ziconotide, compared to 75.8 mm with placebo. This difference, although statistically significant, is clinically irrelevant. The proportion of "responders" (reduction of at least 30% in the initial pain score) was respectively 16.1% and 12.0% (no statistically significant difference); (5) The two other placebo-controlled trials included 112 patients with pain linked to cancer or HIV infection, and 257 patients with non-cancer pain. After a titration phase lasting 5 to 6 days, a combined analysis of the two trials showed that the mean pain score was 48.8 mm with ziconotide and 68.4 mm with placebo (statistically significant difference). However, many patients did not complete the titration phase. Efficacy also appeared to differ according to the type

    2015-10-05

    We present a case series of four previously healthy, employed adults without significant prior medical history in each of whom symptoms developed while on fluoroquinolones (FQs), with progression that continued following discontinuation evolving to a severe, disabling multisymptom profile variably involving tendinopathy, muscle weakness, peripheral neuropathy, autonomic dysfunction, sleep disorder, cognitive dysfunction and psychiatric disturbance. Physicians and patients should be alert to the potential for FQ-induced severe disabling multisymptom pathology that may persist and progress following FQ use. Known induction by FQs of delayed mitochondrial toxicity provides a compatible mechanism, with symptom profiles (and documented mechanisms of FQ toxicity) compatible with the hypothesis of an exposure-induced mitochondrial neurogastrointestinal encephalomyopathy.

    PubMed

    Masuzawa, H; Shimizu, H; Sano, K

    1979-08-01

    Radiographic quality as well as adverse effects of intrathecal metrizamide instillation was prospectively investigated in thirty-three clinical cases admitted to the department of neurosurgery, University of Tokyo Hospital, and Kantoh Teishin Hospital. Metrizamide CT cisternography was performed in fifteen cases using in most cases 10 ml of 170 mg I/ml solution through lumbar route. Eleven cases exhibited "normal" pattern CSF circulation and the remaining four, "delayed" pattern. Eight cases (53%) experienced headache, nausea, and/or vomiting several hours after the instillation. All of these belong to the "normal" pattern group. Four cases of "normal" pattern received electroencephalographic examinations before and after metrizamide instillation. Three revealed appearance of negative spike and slow wave burst or sharp waves one to twenty-four hours after the instillation, along with penetration of metrizamide into brain parenchyma. Diagnostic quality was interpreted as "good" in eleven cases. Small acoustic neurinoma, pituitary adenoma, arachnoid cyst, and subdural hygroma were diagnosed among others. Metrizamide ventriculography was done in four cases. No untoward effect of significance was attributed to metrizamide per se. Cervical myelograpy and/or CT myelography was done in fourteen cases using, in most cases, 10 ml of metrizamide 170 mgI/ml. Polytome tomography with metrizamide instillation through lateral cervical puncture was highly diagnostic, whereas, ordinary X-ray with lumbar instillation yielded less satisfactory results. CT myelography in cases of subarachnoid block required good consideration on instillation site and positioning of the patient. Six cases (50%) among twelve cases where metrizamide had run into the cranial cavity experienced headache, nausea, and/or vomiting to a lesser degree than those of cisterno graphy. Metrizamide is the first contrast agent ever made which can be safely introduced into human subarachnoid space, if administered

    Statins are effective treatment for the prevention of cardiovascular diseases and used extensively worldwide. However, adverse effects induced by statins are the major barrier of maximalizing cardiovascular risk reduction. Hypothyroidism and administration of drugs metabolized on the same cytochrome P450 (CYPP450) pathways where statin biotransformation occurs represent a significant risk factor for statin induced adverse effects including myopathy. Simvastatin, atorvastatin and lovastatin are metabolized by CYP3A4, fluvastatin by CYP2C9, while rosuvastatin by CYP2C9 and 2C19. We investigated the levels of the free thyroid hormones and CYP metabolism of concomitant medication in 101 hyperlipidemic patients (age 61.3 +/- 9.9 ys) with statin induced adverse effects including myopathy (56 cases; 55.4%), hepatopathy (39 cases; 38.6%) and gastrointestinal adverse effects (24 cases; 23.8%). Abnormal thyroid hormone levels were found in 5 patients (4.95%); clinical hypothyroidism in 2 and hyperthyroidism in 3 cases. 11 patients had a positive history for hypothyroidism (10.9%). Myopathy occured in one patient with hypothyroidism and two patients with hyperthyroidism. There were no significant differences in the TSH, fT4 and fT3 levels between patients with statin induced myopathy and patients with other types of adverse effects. 78 patients (77.2%) were administered drugs metabolized by CYP isoforms also used by statins (3A4: 66 cases (65.3%); 2C9: 67 cases (66.3%); 2C19: 54 cases (53.5%)). Patients with myopathy took significantly more drugs metabolized by CYP3A4 compared to patients with other types of adverse effects (p < 0.05). More myopathy cases were found in patients on simvastatin treatment (52% vs. 38%, ns.), while significantly less patients with myopathy were on fluvastatin treatment (13% vs. 33%, p < 0.05) compared to patients with other types of statin induced adverse effects. Both abnormal thyroid hormone status and administration of drugs metabolized by CYP

  17. Dissecting cause and effect in the pathogenesis of psychiatric disorders: genes, environment and behaviour.

    PubMed

    Gray, Laura; Hannan, Anthiny J

    2007-08-01

    It has long been established that the development of psychiatric illness results from a complex interplay between genetic and environmental factors. Postmortem and genetic linkage studies have identified a number of promising candidate genes which have been reinforced by replication and functional studies. However, the fact that concordance rates for monozygotic twins rarely approach 100% highlights the involvement of environmental factors. Whilst epidemiological studies of psychiatric cohorts have demonstrated potential risk factors, such studies are clearly limited and in many cases the potential mechanism linking a given risk factor with pathogenesis remains unclear. A very powerful method of elucidating the mechanisms underlying gene-environment interactions is the use of appropriate animal models of psychiatric pathology. Whilst animals cannot be used to map the entire complexity of diseases such as schizophrenia, dissecting the symptom profile into more simply encapsulated traits or endophenotypes has proved to be a successful approach. Such endophenotypes provide a measurable link between aetiological factors and phenotypic outcome. Given the potential for the careful control and modification of an experimental animal's environment, the combination of studies of candidate genes with investigations of environmental factors is an effective heuristic tool, allowing examination of behavioural endophenotypes in conjunction with cellular and molecular outcomes. This review will consider the extant genetic, molecular, pharmacological and lesion-based models of psychiatric disorders, and the relevant methods of environmental manipulation appearing in the literature. We will discuss studies where such models have been combined, and the potential for future experimentation in this area.

  18. Psychiatric emergencies.

    PubMed

    Cavanaugh, S V

    1986-09-01

    Psychiatric disorders are common in medical inpatient and outpatient populations. As a result, internists commonly are the first to see psychiatric emergencies. As with all medical problems, a good history, including a collateral history from relatives and friends, physical and mental status examination, and appropriate laboratory tests help establish a preliminary diagnosis and treatment plan. Patients with suicidal ideation usually have multiple stressors in the environment and/or a psychiatric disorder (i.e., a major affective disorder, dysthymic disorder, anxiety or panic disorder, psychotic disorder, alcohol or drug abuse, a personality disorder, and/or an adjustment disorder). Of all patients who commit suicide, 70% have a major depressive disorder, schizophrenia, psychotic organic mental disorder, alcoholism, drug abuse, and borderline personality disorder. Patients who are at great risk have minimal supports, a history of previous suicide attempts, a plan with high lethality, hopelessness, psychosis, paranoia, and/or command self-destructive hallucinations. Treatment is directed toward placing the patient in a protected environment and providing psychotropic medication and/or psychotherapy for the underlying psychiatric problem. Other psychiatric emergencies include psychotic and violent patients. Psychotic disorders fall into two categories etiologically: those that have an identifiable organic factor causing the psychosis and those that have an underlying psychiatric disorder. Initially, it is essential to rule out organic pathology that is life-threatening or could cause irreversible brain damage. After such organic causes are ruled out, neuroleptic medication is indicated. If the patient is not agitated or combative, he or she may be placed on oral divided doses of neuroleptics in the antipsychotic range. Patients who are agitated or psychotic need rapid tranquilization with an intramuscular neuroleptic every half hour to 1 hour until the agitation and

    Background Hospitals are currently admitting an increasing number of older people, and more than one-third could have an underlying mental health problem. The existing Older Adult Mental Health (OAMH) liaison service was increasingly unable to meet the escalating needs of older and frail patients. Therefore, the service was modernized and enhanced on an “invest-to-save” principle to provide a prompt holistic assessment for older adults with mental health problems. The objective of this study was a service evaluation to appraise clinical outcome, minimize the length of stay, and measure the predictors of adverse outcomes to streamline this enhanced service. Materials and methods Patient demographics, social care needs, comorbidity burden (Charlson comorbidity index, CCI), and functional status (Barthel index, BI) were recorded from November 2014 to February 2015. Frailty status (frailty index, FI) was measured by an index (Rockwood index) of accumulated deficits. The outcomes were compared with the previous OAMH liaison service data over the same period a year earlier. Results The new Rapid Assessment Interface and Discharge service assessed 339 patients compared to 179 by the previous liaison team over the 4-month period. Mean age was 82.18±8.04 years, with 60% women; preadmission BI was 14.96±4.35, and admission BI was 11.38±5.73 (P<0.001, paired t-test); mean CCI was 1.66±1.53, and mean FI was 0.34±0.99, and 80% were on polypharmacy. The direct discharges from front door were increased by 7%. The mean hospital stay reduced from 35 to 20 days in acute site and from 108 to 47 days in long-stay wards. The cost benefits were based on the mean reduction in hospital stay (41.8 days) and admission reduction (2.2 days), leading to a total annualized bed savings of 44 days. FI was the most highly significant factor between patient groups with a good and poor outcome (P=0.00003, independent groups t-test, t=−4.38, df 98). Conclusion Prompt mental health

  20. The lifelong effects of early childhood adversity and toxic stress.

    PubMed

    Boyce, W Thomas

    2014-01-01

    A rapidly expanding body of research indicates that early social environments characterized by adversity, subordination and stress, along with individual differences in susceptibility to such environments, create risks for lifelong chronic diseases, including declines in oral health. Emerging findings suggest that gene-environment interplay, resulting in epigenetically regulated differences in gene expression, underlie many such declines in health. The origins of these processes in early life reveal how many of the chronic morbidities of adulthood should be viewed as developmental disorders, with etiologic roots in childhood.

  1. Psychiatric disorders and sleep issues.

    PubMed

    Sutton, Eliza L

    2014-09-01

    Sleep issues are common in people with psychiatric disorders, and the interaction is complex. Sleep disorders, particularly insomnia, can precede and predispose to psychiatric disorders, can be comorbid with and exacerbate psychiatric disorders, and can occur as part of psychiatric disorders. Sleep disorders can mimic psychiatric disorders or result from medication given for psychiatric disorders. Impairment of sleep and of mental health may be different manifestations of the same underlying neurobiological processes. For the primary care physician, key tools include recognition of potential sleep effects of psychiatric medications and familiarity with treatment approaches for insomnia in depression and anxiety.

    2012-06-01

    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.

    The benefits of clinical neurofeedback training are well known, however, its adverse side-effects are less studied. This research focuses on the transient adverse side effects of neurofeedback training via a double-blind, sham/controlled methodology. Thirty healthy undergraduate students volunteers were randomly divided into three treatment groups: increasing a modified Sensory Motor Rhythm, increasing Upper Alpha, and Sham/control group who receive a random reward. The training sessions were administered for a total of ten sessions. Questionnaires of transient adverse side effects were completed by all volunteers before each session. The results suggest that similar to most medical treatments, neurofeedback can cause transient adverse side effects. Moreover, most participants reported experiencing some side effects. The side effects can be divided into non-specific side effect, associated with the neurofeedback training in general and specific ones associated with the particular protocol. Sensory Motor Rhythm protocol seems to be the most sensitive to side effects.

    Background The rapid expansion of online video gaming as a leisure time activity has led to the appearance of problematic online gaming (POG). According to the literature, POG is associated with different psychiatric symptoms (eg, depression, anxiety) and with specific gaming motives (ie, escape, achievement). Based on studies of alcohol use that suggest a mediator role of drinking motives between distal influences (eg, trauma symptoms) and drinking problems, this study examined the assumption that there is an indirect link between psychiatric distress and POG via the mediation of gaming motives. Furthermore, it was also assumed that there was a moderator effect of gender and game type preference based on the important role gender plays in POG and the structural differences between different game types. Objective This study had two aims. The first aim was to test the mediating role of online gaming motives between psychiatric symptoms and problematic use of online games. The second aim was to test the moderator effect of gender and game type preference in this mediation model. Methods An online survey was conducted on a sample of online gamers (N=3186; age: mean 21.1, SD 5.9 years; male: 2859/3186, 89.74%). The Brief Symptom Inventory (BSI), the Motives for Online Gaming Questionnaire (MOGQ), and the Problematic Online Gaming Questionnaire (POGQ) were administered to assess general psychiatric distress, online gaming motives, and problematic online game use, respectively. Structural regression analyses within structural equation modeling were used to test the proposed mediation models and multigroup analyses were used to test gender and game type differences to determine possible moderating effects. Results The mediation models fitted the data adequately. The Global Severity Index (GSI) of the BSI indicated that the level of psychiatric distress had a significant positive direct effect (standardized effect=.35, P<.001) and a significant indirect (mediating) effect

    The purpose of this study was to implement and measure the effectiveness of a single-session assertiveness music therapy role playing protocol for psychiatric inpatients. Participants (N=133) were randomly assigned by group to one of three conditions: (a) Assertiveness Music Therapy, (b) No Music Assertiveness, or (c) Music No Assertiveness. Participants in both assertiveness conditions role played a number of different commonly occurring scenarios at an inpatient psychiatric facility and in the community. There were no significant between-group differences in posttest quality of life, locus of control, or other subscales. However, participants in both assertiveness conditions tended to have slightly higher internal locus of control and overall quality of life scores than participants in the music no assertiveness condition. Additionally, the assertiveness music therapy condition had higher attendance rates than the other conditions. A higher percentage of participants from both the assertiveness music therapy and music no assertiveness conditions indicated they thought their session was the most helpful/therapeutic group therapy session in which they had participated; this was not the case for the assertiveness no music condition. Future research is warranted to measure the effects of protocols that can help psychiatric patients generalize skills learned in treatment.

    Morphine is the gold-standard pain reliever for severe acute or chronic pain but it also produces adverse side effects that can alter the quality of life of patients and, in some rare cases, jeopardize the vital prognosis. Morphine elicits both therapeutic and adverse effects primarily through the same μ opioid receptor subtype, which makes it difficult to separate the two types of effects. Here we show that beneficial and deleterious effects of morphine are mediated through different signalling pathways downstream from μ opioid receptor. We demonstrate that the TREK-1 K(+) channel is a crucial contributor of morphine-induced analgesia in mice, while it is not involved in morphine-induced constipation, respiratory depression and dependence-three main adverse effects of opioid analgesic therapy. These observations suggest that direct activation of the TREK-1 K(+) channel, acting downstream from the μ opioid receptor, might have strong analgesic effects without opioid-like adverse effects.

    The impact of the micro-blowing technique (MBT) on the skin friction and total drag of a strut in a turbulent, strong adverse-pressure-gradient flow is assessed experimentally over a range of subsonic Mach numbers (0.3 less than M less than 0.7) and reduced blowing fractions (0 less than or equal to 2F/C (sub f,o) less than or equal to 1.75). The MBT-treated strut is situated along the centerline of a symmetric 2-D diffuser with a static pressure rise coefficient of 0.6. In agreement with presented theory and earlier experiments in zero-pressure-gradient flows, the effusion of blowing air reduces skin friction significantly (e.g., by 60% at reduced blowing fractions near 1.75). The total drag of the treated strut with blowing is significantly lower than that of the treated strut in the limit of zero-blowing; further, the total drag is reduced below that of the baseline (solid-plate) strut, provided that the reduced blowing fractions are sufficiently high. The micro-blowing air is, however, deficient in streamwise momentum and the blowing leads to increased boundary-layer and wake thicknesses and shape factors. Diffuser performance metrics and wake surveys are used to discuss the impact of various levels of micro-blowing on the aerodynamic blockage and loss.

    We investigate the effects of music therapy concerts, which were held 60 times over a four year period, 1992 to 1996, in Geiyo Psychiatric Hospital, Kochi Prefecture and found that; 1) Musicians who performed at the concerts were not only from Kochi prefecture but also from other prefectures (10 times) and from four foreign countries (7 times). 2) Live concerts in a small hall had a positive influence on patients and drew the patient's attention and interest away from their hallucinations and delusions to the real world. Moreover, the concerts provided the patients with chances to acquire social graces such as being well-groomed. 3) Explanations by the musicians, interviews with the musicians and the seasonal choruses accompanied by the musicians were helpful to give the patients motives for recovering communication skills and to interact with society. 4) Inquiries to the patients about the concerts indicated discrepancies between the poor observed estimations during the concerts (83.3%) and the good subjective impressions expressed by the patients (82.0%), suggesting that the patients were not good at expressing their internal emotions through facial expressions or attitudes. 5) Many citizens including children came to the concerts and/or gave aid to the hospital because the concerts were open to the public and we suggest that this contributed to improving the general publics' image of psychiatric hospitals. Questionnaires revealed that 90% of people in a control group had a bad image of psychiatric hospitals in Japan, but only 32% of the members of the general public who attended our concerts had a bad image of psychiatric hospitals. In addition, the revolving ratio of the hospital beds rose from 0.4 to 1.2 over the four years, which also suggests a beneficial effect on the patients.

  7. Adverse effects of extra-articular corticosteroid injections: a systematic review

    PubMed Central

    2010-01-01

    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. PMID:20836867

    BACKGROUND: The use of antidepressant medications and the resulting costs have increased dramatically in recent years, partly because of the introduction of selective serotonin reuptake inhibitors (SSRIs). An assessment of the clinical and economic aspects of SSRIs compared with the older tricyclic antidepressants (TCAs) was initiated to generate information for purchasers of these drugs as well as clinicians. One component of this study was an examination of the adverse effects associated with the use of these drugs. METHODS: Searches of bibliographic databases (for January 1980 through May 1996) and manual scanning of both peer-reviewed publications and other documents were used to identify double-blind, randomized controlled trials involving at least one SSRI and one TCA. For the study of adverse effects, only trials that had at least 20 patients in each trial arm and that reported rates of adverse effects in both arms were retained. In total 84 trials reporting on 18 adverse effects were available. Meta-analyses were undertaken to calculate pooled differences in rates of adverse effects. The question of whether the method of eliciting information from patients about adverse effects made a difference in the findings was also examined. Finally, differences in drop-out rates due to adverse effects were calculated. RESULTS: The crude rates of occurrence of adverse effects ranged from 4% (palpitations) to 26% (nausea) for SSRIs and from 4% (diarrhea) to 27% (dry mouth) for TCAs. The differences in the rates of adverse effects between the 2 types of drugs ranged from 14% more with SSRIs (for nausea) to 11% more with TCAs (for constipation). The results did not depend on the method of eliciting information from patients. There were no statistically significant differences between drug classes in terms of drop-outs due to adverse effects. INTERPRETATION: SSRIs and TCAs are both associated with adverse effects, although the key effects differ between the drug classes

    Because of advances in surgical technique, radiation therapy, and combined chemotherapy regimens, there has been a dramatic improvement in the survival of children with pediatric malignancies. All treatment modalities are associated with adverse effects that may be manifested months to years after therapy. This article has provided an overview of the physiologic and psychologic adverse effects of antineoplastic therapy and described the multidisciplinary approach used by one institution to identify and initiate appropriate remedial intervention. Nurses can learn to assist in the identification of adverse late effects, provide support to the family, and facilitate appropriate intervention.

    Immunoglobulin therapy has not only served as a lifesaving approach for the prevention and treatment of infections in primary and secondary immunodeficiency diseases, but has also been used as an immunomodulatory agent for autoimmune and inflammatory disorders and to provide passive immunity for some infectious diseases. Most of the adverse effects associated with immunoglobulin therapy are mild, transient and self-limiting. However, serious side effects also occur. Therefore, to minimize the adverse events of immunoglobulin therapy, specialist review of patient clinical status and immunoglobulin products, in addition to selection of appropriate treatment strategy for the management of patients with associated side effects and adverse events, are crucial.

    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.

    African American girls in psychiatric care are at increased risk for HIV and sexually transmitted infection (STI) through sexual risk taking. Adolescent sexual behavior often reflects peer norms and behavior. Secure attachment patterns with mothers and peers might lessen the effects of negative peer influences and reduce sexual risk taking among African American girls. This study examined the relationships among mother-daughter and peer attachment, peer norms, and sexual-risk behaviors in African American girls seeking outpatient psychiatric care. A group of 12-16-year-old African American girls (N = 262; M age = 14.45 years) reported on their attachment to their mothers and peers, peer risk-taking and dating behaviors, peer pressure, and sexual-risk behaviors (e.g., number of partners, high-risk partners, and condom use). Structural equation modeling examined whether peer attachment and peer norms mediated the relationship between mother attachment and sexual risk. Findings supported peer norms, but not peer attachment, as a mediator of mother attachment and girls' sexual-risk behaviors. Findings revealed important family and peer factors for African American girls in psychiatric care. HIV prevention programs may be strengthened by improving mother-daughter relationships, addressing the importance of peer relationships, and emphasizing how secure mother-daughter relationships can temper the impact of peer norms.

  13. Alcohol and cannabis: Comparing their adverse health effects and regulatory regimes.

    2016-11-28

    The claim that the adverse health effects of cannabis are much less serious than those of alcohol has been central to the case for cannabis legalisation. Regulators in US states that have legalised cannabis have adopted regulatory models based on alcohol. This paper critically examines the claim about adverse health effects and the wisdom of regulating cannabis like alcohol. First, it compares what we know about the adverse health effects of alcohol and cannabis. Second, it discusses the uncertainties about the long term health effects of sustained daily cannabis use. Third, it speculates about how the adverse health effects of cannabis may change after legalisation. Fourth, it questions the assumption that alcohol provides the best regulatory model for a legal cannabis market. Fifth, it outlines the major challenges in regulating cannabis under the liberal alcohol-like regulatory regimes now being introduced.

  14. The Useage of Opioids and their Adverse Effects in Gastrointestinal Practice: A Review

    Opium is one of the oldest herbal medicines currently used as an analgesic, sedative and antidiarrheal treatment. The effects of opium are principally mediated by the μ-, κ- and δ-opioid receptors. Opioid substances consist of all natural and synthetic alkaloids that are derived from opium. Most of their effects on gastrointestinal motility and secretion result from suppression of neural activity. Inhibition of gastric emptying, increase in sphincter tone, changes in motor patterns, and blockage of peristalsis result from opioid use. Common adverse effects of opioid administration include sedation, dizziness, nausea, vomiting, constipation, dependency and tolerance, and respiratory depression. The most common adverse effect of opioid use is constipation. Although stool softeners are frequently used to decrease opioid-induced bowel dysfunction, however they are not efficacious. Possibly, the use of specific opioid receptor antagonists is a more suitable approach. Opioid antagonists, both central and peripheral, could affect gastrointestinal function and visceromotor sensitivity, which suggests an important role for endogenous opioid peptides in the control of gastrointestinal physiology. Underlying diseases or medications known to influence the central nervous system (CNS) often accelerate the opioid’s adverse effects. However, changing the opioid and/or route of administration could also decrease their adverse effects. Appropriate patient selection, patient education and discussion regarding potential adverse effects may assist physicians in maximizing the effectiveness of opioids, while reducing the number and severity of adverse effects.

    2016-04-01

    The Short-Term Assessment of Risk and Treatability (START) aims to assist mental health practitioners to estimate an individual's short-term risk for a range of adverse outcomes via structured consideration of their risk ("Vulnerabilities") and protective factors ("Strengths") in 20 areas. It has demonstrated predictive validity for aggression but this is less established for other outcomes. We collated START assessments for N = 200 adults in a secure mental health hospital and ascertained 3-month risk event incidence using the START Outcomes Scale. The specific risk estimates, which are the tool developers' suggested method of overall assessment, predicted aggression, self-harm/suicidality, and victimization, and had incremental validity over the Strength and Vulnerability scales for these outcomes. The Strength scale had incremental validity over the Vulnerability scale for aggressive outcomes; therefore, consideration of protective factors had demonstrable value in their prediction. Further evidence is required to support use of the START for the full range of outcomes it aims to predict.

    Until 2002, counties were responsible for providing both somatic and psychiatric specialized health care services in Norway. The financing arrangement of the counties consisted of fixed local taxes, a general block grant and different types of earmarked grants from the national government. Since 1997, earmarked conditional grants related to DRG-activity have been used for somatic services, whereas earmarked unconditional grants have been used for mental health care services from approximately the same time. This paper analyse the price and revenue effects of grants on the allocation of labour, with special attention to the two types of earmarked grants: conditional and unconditional. Theoretically, labour (as an index of production output) is assumed to be allocated to somatic and psychiatric services dependent upon revenues (taxes, block grants and earmarked unconditional grants), price per labour-year (that among other things are affected by earmarked conditional grants) and the preferences of the local government (which relate to the age structure and population density of the county). We assume that a conditional grant reduces the net price of labour and thereby increases the (relative) demand, whereas an unconditional grant adds to the other revenues of the county and do not affect the relative allocation of labour. Data from a panel of 18 counties for the period 1992-2001 is analysed using OLS with fixed effects. The results show revenue effects and direct price effects as expected. However, the assumption that unconditional grants do not affect relative allocation of labours is not supported. We find a positive effect of the unconditional grant to psychiatric care on the demand for labour in this sector. We interpret this as an effect of hierarchical governance such as supervision and monitoring that were remedies that were used together with the unconditional grant.

  19. Knowledge of Psychiatric Nurses About the Potentially Lethal Side-Effects of Clozapine.

    Clozapine is an antipsychotic with superior efficacy in treatment refractory patients, and has unique anti-suicidal properties and a low propensity to cause extrapyramidal side-effects. Despite these advantages, clozapine utilization is low. This can in part be explained by a number of potentially lethal side effects of clozapine. Next to psychiatrists nurses play a crucial role in the long-term management of patients with schizophrenia. It is therefore important that nurses know, inform and monitor patients about the specific side-effects of clozapine. A recent study of psychiatrists published in 2011 has shown that there was a gap in the knowledge about side-effects of clozapine. The knowledge about side-effects of clozapine in nurses has never been studied. This cross-sectional study evaluated the knowledge base regarding the safety of clozapine, and its potential mediators, of psychiatric nurses in 3 psychiatric hospitals in Belgium with a specifically developed questionnaire based on the literature and expert opinion (3 clozapine experts). A total of 85 nurses completed the questionnaire. The mean total score was 6.1 of a potential maximum score of 18. Only 3 of the 18 multiple choice knowledge questions were answered correctly by more than 50% of nurses. Only 24.9% of participants passed the test (>50% correct answers). Nurses working on psychosis units were more likely to pass the test (xx.y% vs yy.z%, p=0.0124). There was a trend that nurses with a lower nursing diploma were more likely to fail the test (p=0.0561). Our study clearly identifies a large gap in the basic knowledge of psychiatric nurses about clozapine and its side-effects. Knowledge could be increased by more emphasis on the topic in nurse's training curricula as well as targeted onsite training. Only 23.5% of participants indicate that there was sufficient information in their basic nursing training.

    The adverse effects profile of levetiracetam in epilepsy is still being fully described. We recently published a Cochrane Review evaluating the effectiveness of levetiracetam, added on to usual care, in treating drug-resistant focal epilepsy. The five most common adverse effects were reported and analysed with no scope for reporting any less common adverse effects than those. Here, we report and analyse the remaining adverse effects (including the five most common). These were (in decreasing order of frequency) somnolence; headache; asthenia; accidental injury; dizziness; infection; pharyngitis; pain; rhinitis; abdominal pain; flu syndrome; vomiting; diarrhoea; convulsion; nausea; increased cough; anorexia; upper respiratory tract infection; hostility; personality disorder; urinary tract infection; nervousness; depression; aggression; back pain; agitation; emotional liability; psychomotor hyperactivity; pyrexia; rash; ECG abnormalities; decreased appetite; nasal congestion; irritability; abnormal behaviour; epistaxis; insomnia; altered mood; anxiety; bloody urine; diplopia; dissociation; memory impairment; pruritis; increased appetite; acne; and stomach discomfort. Only somnolence and infection were significantly associated with levetiracetam. When adverse effects pertaining to infection were combined, these affected 19.7% and 15.1% of participants on levetiracetam and placebo (relative risk 1.16, CI 0.89-1.50, Chi(2) heterogeneity p = 0.13). Somnolence and infection further retained significance in adults while no single adverse effect was significant in children. This review updates the adverse effects profile data on levetiracetam use by empirically reporting its common and uncommon adverse effects and analysing their relative importance statistically using data from a group of trials that possess low Risk of Bias and high Quality of Evidence GRADE scores.

    Background: The frequent use of corticosteroid inhalers (CSIs), especially at higher doses, has been accompanied by concern about both systemic and local adverse reactions. The local adverse reactions of inhaled corticosteroids (ICSs) are considered to constitute infrequent and minor problems. However, while not usually serious, these local adverse reactions are of clinical importance. This study assessed the prevalence of local adverse reactions, their clinical features, role of inhaler devices and current measures that have been suggested to prevent the problem. Materials and Methods: This study was performed in YAS clinic in Tabriz on 500 asthmatic patients. A questionnaire about the patients’ demographic information, methods of using CSIs, local care after using CSIs, using spacer devices, doses of ICSs, and adverse reactions were filled then the patients were clinically examined for local adverse reactions. Results: Only 56% patients were using CSIs properly. In general, the incidence of complications was: oropharyngeal candidiasis 25.6%, laryngeal weakness 8.8%, choking 17.6%, tooth decay 15.2%, speechlessness 36.2%, taste decrease 20.8%, tongue burning 29.8% and tongue abrasion 27.8%. Conclusion: Persistent asthma can be effectively controlled with currently available CSIs. Although not life-threatening, local adverse reactions of ICSs are clinically significant and warrant attention. Use of spacer devices and changes in CSI usage, dosage amount and frequency and rinsing and gargling are the methods that have been used to reduce the incidence of local adverse reactions.

    Objective:To test the hypothesis that among adolescent smokers hospitalised for psychiatric and substance use disorders, motivational interviewing (MI) would lead to more and longer quit attempts, reduced smoking, and more abstinence from smoking over a 12 month follow up. Design:Randomised control trial of MI versus brief advice (BA) for smoking cessation, with pre- and post-intervention assessment of self efficacy and intentions to change, and smoking outcome variables assessed at one, three, six, nine, and 12 month follow ups. Setting:A private, university affiliated psychiatric hospital in Providence, Rhode Island, USA. Patients or other participants:Consecutive sample (n = 191) of 13–17 year olds, admitted for psychiatric hospitalisation, who smoked at least one cigarette per week for the past four weeks, had access to a telephone, and did not meet DSM-IV criteria for current psychotic disorder. Interventions:MI versus BA. MI consisted of two, 45 minute individual sessions, while BA consisted of 5–10 minutes of advice and information on how to quit smoking. Eligible participants in both conditions were offered an eight week regimen of transdermal nicotine patch upon hospital discharge. Main outcome measures:Point prevalence abstinence, quit attempts, changes in smoking rate and longest quit attempt. Proximal outcomes included intent to change smoking behaviour (upon hospital discharge), and self efficacy for smoking cessation. Results:MI did not lead to better smoking outcomes compared to BA. MI was more effective than BA for increasing self efficacy regarding ability to quit smoking. A significant interaction of treatment with baseline intention to quit smoking was also found. MI was more effective than BA for adolescents with little or no intention to change their smoking, but was actually less effective for adolescents with pre-existing intention to cut down or quit smoking. However, the effects on these variables were relatively modest and only

    Weight gain has been identified as being responsible for increased morbidity and mortality rates of schizophrenia patients. For the management of weight gain, exercise is one of the most acknowledged interventions. At the same time, exercise and sports have been recognized for their positive impact on psychiatric symptoms of schizophrenia. However, the neurobiological basis for this remains poorly understood. We aimed to examine the effect of sports participation on weight gain, psychiatric symptoms and brain activation during sports observation in schizophrenia patients. Thirteen schizophrenia patients who participated in a 3-month program, including sports participation and 10 control schizophrenia patients were studied. In both groups, body mass index (BMI), Positive and Negative Syndrome Scale (PANSS), and brain activation during observation of sports-related actions measured by functional magnetic resonance imaging were accessed before and after a 3-month interval. BMI and general psychopathology scale of PANSS were significantly reduced in the program group but not in the control group after a 3-month interval. Compared with baseline, activation of the body-selective extrastriate body area (EBA) in the posterior temporal-occipital cortex during observation of sports-related actions was increased in the program group. In this group, increase in EBA activation was associated with improvement in the general psychopathology scale of PANSS. Sports participation had a positive effect not only on weight gain but also on psychiatric symptoms in schizophrenia. EBA might mediate these beneficial effects of sports participation. Our findings merit further investigation of neurobiological mechanisms underlying the therapeutic effect of sports for schizophrenia.

    The effects of calcium inhibitors are not limited to the muscles and may affect other systems and cause varied side effects. Two cases of Parkinsonian syndrome occurring after starting therapy with calcium inhibitors (verapamil in one case and diltiazem in the other) are reported. Complete regression of the symptoms after withdrawing the drugs was strongly in favour of a causal relationship. The condition could be due to inhibition of the calcium channels in the central nervous system disturbing neurotransmission. This seems to be a rare side effect as there have only been three other reported cases of secondary extrapyramidal syndromes in the literature. However, a Parkinsonian syndrome is very invalidating and clinicians using this family of drugs should be aware of this possible complication.

    We report a case of a 28-year-old major depressive female patient who manifested ecchymoses following fluoxetine use. After substitution of sertraline, her depression resolved after 4 weeks and ecchymoses 1.5 months latter. This is an unexplored side-effect with unknown long-term consequences that warrants further study.

  7. Concrete blocks` adverse effects on indoor air and recommended solutions

    Ruppersberger, J.S.

    1995-04-01

    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/m{sup 2} 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.

    Research conducted during the last decades has provided increasing evidence for the use of psychological treatments for a number of psychiatric disorders and somatic complaints. However, by focusing only on the positive outcomes, less attention has been given to the potential of negative effects. Despite indications of deterioration and other adverse and unwanted events during treatment, little is known about their occurrence and characteristics. Hence, in order to facilitate research of negative effects, a new instrument for monitoring and reporting their incidence and impact was developed using a consensus among researchers, self-reports by patients, and a literature review: the Negative Effects Questionnaire. Participants were recruited via a smartphone-delivered self-help treatment for social anxiety disorder and through the media (N = 653). An exploratory factor analysis was performed, resulting in a six-factor solution with 32 items, accounting for 57.64% of the variance. The derived factors were: symptoms, quality, dependency, stigma, hopelessness, and failure. Items related to unpleasant memories, stress, and anxiety were experienced by more than one-third of the participants. Further, increased or novel symptoms, as well as lack of quality in the treatment and therapeutic relationship rendered the highest self-reported negative impact. In addition, the findings were discussed in relation to prior research and other similar instruments of adverse and unwanted events, giving credence to the items that are included. The instrument is presently available in eleven different languages and can be freely downloaded and used from www.neqscale.com. PMID:27331907

    2016-01-01

    The management guideline for traumatic brain injury (TBI) recommends high-dose barbiturate therapy to control increased intracranial pressure refractory to other therapeutic options. High-dose barbiturate therapy, however, may cause many severe side effects; the commonly recognized ones include hypotension, immunosuppression, hepatic dysfunction, renal dysfunction, and prolonged decrease of cortical activity. Meanwhile, dyskalemia remains relatively uncommon. In this study, we report the case of a hypokalemic patient with severe rebound hyperkalemia, which occurred as a result of barbiturate coma therapy administered for TBI treatment. PMID:27857927

    Buprenorphine in sublingual formulation was recently introduced to the American market for treatment of opioid dependence. We report a series of 5 toddlers with respiratory and mental-status depression after unintentional buprenorphine exposure. Despite buprenorphine's partial agonist activity and ceiling effect on respiratory depression, all children required hospital admission and either opioid-antagonist therapy or mechanical ventilation. Results of routine urine toxicology screening for opioids were negative in all cases. Confirmatory testing was sent for 1 child and returned with a positive result. The increasing use of buprenorphine as a home-based therapy for opioid addiction in the United States raises public health concerns for the pediatric population.

    2009-01-01

    Context: This review describes the health effects of beryllium exposure in the workplace and the environment. Aim: To collate information on the consequences of occupational and environmental exposure to beryllium on physiological function and well being. Materials and Methods: The criteria used in the current review for selecting articles were adopted from proposed criteria in The International Classification of Functioning, Disability, and Health. Articles were classified based on acute and chronic exposure and toxicity of beryllium. Results: The proportions of utilized and nonutilized articles were tabulated. Years 2001–10 gave the greatest match (45.9%) for methodological parameters, followed by 27.71% for 1991–2000. Years 1971–80 and 1981–90 were not significantly different in the information published and available whereas years 1951–1960 showed a lack of suitable articles. Some articles were published in sources unobtainable through requests at the British Library, and some had no impact factor and were excluded. Conclusion: Beryllium has some useful but undoubtedly harmful effects on health and well-being. Measures need to be taken to prevent hazardous exposure to this element, making its biological monitoring in the workplace essential. PMID:20386622

  13. The Adverse Effects of Alcohol on Vitamin A Metabolism

    2012-01-01

    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.

    2016-01-01

    Introduction Working at unusual hours has been found to be related to sleep problems, psychiatric symptoms, and low quality of life. This study aimed to investigate the effect of sleep quality on psychiatric symptoms and the quality of life in newspaper couriers who permanently wake up at early morning hours. Methods Thirty-five newspaper couriers who worked for a media company in Ankara and 35 healthy individuals who worked at usual hours and who were matched according to age, gender, and work duration were included in the study. All individuals were evaluated using the demographic forms, Symptom Checklist (SCL)-90-R, Pittsburg Sleep Quality Index (PSQI), and Short Form-36 (SF-36). Results The somatization subscale of SCL-90-R and the sleep duration sub-component scores of PSQI were significantly higher and the physical role functioning domain score of SF-36 was significantly lower in newspaper couriers compared with the scores in healthy individuals. There were significantly positive correlations between the PSQI total and sub-component scores and the SCL-90-R subscale and global symptom index scores. There were significantly negative correlations between the PSQI total and sub-component scores and the SF-36 domain scores. Conclusion This study demonstrates that waking up permanently at early morning hours may be related to sleep disturbances, psychiatric symptoms, and low quality of life. Measures to increase sleep quality in individuals working at unusual hours may improve their mental health and quality of life. Future studies should investigate the effects of interventions toward sleep disturbances on mental health and quality of life in different occupational groups.

    1996-07-17

    Utah Valley has provided an interesting and unique opportunity to evaluate the health effects of respirable particulate air pollution (PM10). Residents of this valley are predominantly nonsmoking members of the Church of Jesus Christ of Latter-day Saints (Mormons). The area has moderately high average PM10 levels with periods of highly elevated PM10 concentrations due to local emissions being trapped in a stagnant air mass near the valley floor during low-level temperature inversion episodes. Due to a labor dispute, there was intermittent operation of the single largest pollution source, an old integrated steel mill. Levels of other common pollutants including sulfur dioxide, ozone, and acidic aerosol are relatively low. Studies specific to Utah Valley have observed that elevated PM10 concentrations are associated with: (1) decreased lung function; (2) increased incidence of respiratory symptoms; (3) increased school absenteeism; (4) increased respiratory hospital admissions; and (5) increased mortality, especially respiratory and cardiovascular mortality.

    Psychiatric abuse, such as we usually associate with practices in the former Soviet Union, is related not to the misuse of psychiatric diagnoses, but to the political power intrinsic to the social role of the psychiatrist in totalitarian and democratic societies alike. Some reflections are offered on the modern, therapeutic state's proclivity to treat adults as patients rather than citizens, disjoin rights from responsibilities, and thus corrupt the language of political-philosophical discourse.

    Objective Cardiovascular disease (CVD) is the leading cause of death in severe psychiatric disorders (depression, schizophrenia). Here, we provide evidence of how the effects of oxidative stress on fatty acid (FA) and one-carbon (1-C) cycle metabolism, which may initially represent adaptive responses, might underlie comorbidity between CVD and psychiatric disorders. Method We conducted a literature search and integrated data in a narrative review. Results Oxidative stress, mainly generated in mitochondria, is implicated in both psychiatric and cardiovascular pathophysiology. Oxidative stress affects the intrinsically linked FA and 1-C cycle metabolism: FAs decrease in chain length and unsaturation (particularly omega-3 polyunsaturated FAs), and lipid peroxidation products increase; the 1-C cycle shifts from the methylation to transsulfuration pathway (lower folate and higher homocysteine and antioxidant glutathione). Interestingly, corresponding alterations were reported in psychiatric disorders and CVD. Potential mechanisms through which FA and 1-C cycle metabolism may be involved in brain (neurocognition, mood regulation) and cardiovascular system functioning (inflammation, thrombosis) include membrane peroxidizability and fluidity, eicosanoid synthesis, neuroprotection and epigenetics. Conclusion While oxidative-stress-induced alterations in FA and 1-C metabolism may initially enhance oxidative stress resistance, persisting chronically, they may cause damage possibly underlying (co-occurrence of) psychiatric disorders and CVD. This might have implications for research into diagnosis and (preventive) treatment of (CVD in) psychiatric patients. PMID:24649967

    In this study, we investigated the relation between global and domain-specific self-esteem and psychiatric disorders. A sample of 577 children aged 8-14 years was recruited via psychiatric hospitals and from the general population. Parents were given a diagnostic interview to assess children's psychiatric diagnoses (current/past). Parents and children completed questionnaires on child symptoms. Children completed a questionnaire on global and domain-specific self-esteem (scales: scholastic competence, social acceptance, athletic performance and physical appearance, global self-esteem). Self-esteem of children with current psychiatric disorders was lower than that of healthy controls (η p(2) between 0.01 and 0.08). Concerning scholastic competence, social acceptance and global self-esteem, children with past psychiatric disorders scored also lower than healthy controls. Different current psychiatric disorders showed specific but small effects on dimensions of self-esteem (β between -0.08 and 0.19). Moreover, we found a gender × group interaction, indicating that girls with depressive and adjustment disorders were specifically impaired in their global self-esteem and perception of their physical appearance. Findings might help clinicians to focus on particular domains of self-esteem during the diagnostic process and to define adequate treatment goals.

    Autoimmune disease has affected up to 50 million Americans, according to the American Autoimmune Related Diseases Association (AARDA) and 75 percent of those affected are women. These inflammatory diseases have variable activity and a lot of women will have to undergo major therapies during and after pregnancy. Many of the women suffering from these disease will improve during gestation. However a lot of women will require continuation of disease-modifying therapies (i.e., biological therapies) throughout pregnancy and post-partum involving many risks. In the past decade all gaze turned to biological therapies, as an attempt, to obtain even more effective medications in order to suppress the exacerbation of autoimmune disease, even at the most unfit circumstances such as pregnancy. The results are both satisfying and promising since increasingly proven thoughts prevail on making anti-TNF agents first-line medications, clearing up the limited knowledge over human influence. The purpose of this review is to summarize the results of the reports with the highest and representative range of patients of the last decade involving the use of anti-TNF agents during pregnancy.

    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

    Introduction. Aerobic exercise performed after hospital discharge for exacerbated COPD patients is already recommended to improve respiratory and skeletal muscle strength, increase tolerance to activity, and reduce the sensation of dyspnea. Previous studies have shown that anaerobic activity can clinically benefit patients hospitalized with exacerbated COPD. However, there is little information on the feasibility and safety of aerobic physical activity performed by patients with exacerbated COPD during hospitalization. Objective. To evaluate the effects of aerobic exercise on vital signs in hospitalized patients with exacerbated COPD. Patients and Methods. Eleven COPD patients (63% female, FEV1: 34.2 ± 13.9% and age: 65 ± 11 years) agreed to participate. Aerobic exercise was initiated 72 hours after admission on a treadmill; speed was obtained from the distance covered in a 6-minute walk test (6MWT). Vital signs were assessed before and after exercise. Results. During the activity systolic blood pressure increased from 125.2 ± 13.6 to 135.8 ± 15.0 mmHg (p = 0.004) and respiratory rate from 20.9 ± 4.4 to 24.2 ± 4.5 rpm (p = 0.008) and pulse oximetry (SpO2) decreased from 93.8 ± 2.3 to 88.5 ± 5.7% (p < 0.001). Aerobic activity was considered intense, heart rate ranged from 99.2 ± 11.5 to 119.1 ± 11.1 bpm at the end of exercise (p = 0.092), and patients reached on average 76% of maximum heart rate. Conclusion. Aerobic exercise conducted after 72 hours of hospitalization in patients with exacerbated COPD appears to be safe. PMID:28265180

    Abnormal parasympathetic nervous system (PNS)-related cardiac activity has been linked to aggression. However, little is known about how it interacts with psychosocial adversity in predisposing to reactive-proactive aggression. In the current study, 84 male and female college students self-reported reactive and proactive aggression, and were assessed for respiratory sinus arrhythmia (RSA), a measure of PNS-related cardiac activity, during rest and when they contemplated an emotion-evoking decision-making task. Regression analyses showed that (a) resting RSA was positively linked to reactive aggression in conditions of high social adversity, and (b) RSA reactivity was positively associated with reactive but negatively associated with proactive aggression, in conditions of low social adversity. Main effects were not found for psychophysiological functioning or psychosocial adversity, suggesting the importance of their interaction. Findings support a biosocial basis for aggression and add additional support for the distinctions between reactive and proactive aggression.

    Objective: Framed in the patients' engagement perspective, the current study aims to determine the effects of group music therapy in addition to drug care in comparison with drug care in addition to other non-expressive group activities in the treatment of psychiatric outpatients. Method: Participants (n = 27) with ICD-10 diagnoses of F20 (schizophrenia), F25 (schizoaffective disorders), F31 (bipolar affective disorder), F32 (depressive episode), and F60 (specific personality disorders) were randomized to receive group music therapy plus standard care (48 weekly sessions of 2 h) or standard care only. The clinical measures included dosages of neuroleptics, benzodiazepines, mood stabilizers, and antidepressants. Results: The participants who received group music therapy demonstrated greater improvement in drug dosage with respect to neuroleptics than those who did not receive group music therapy. Antidepressants had an increment for both groups that was significant only for the control group. Benzodiazepines and mood stabilizers did not show any significant change in either group. Conclusion: Group music therapy combined with standard drug care was effective for controlling neuroleptic drug dosages in adult psychiatric outpatients who received group music therapy. We discussed the likely applications of group music therapy in psychiatry and the possible contribution of music therapy in improving the psychopathological condition of adult outpatients. In addition, the implications for the patient-centered perspective were also discussed.

    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 < 0.001). Location and cortical eloquence were not significantly associated with the development of adverse events (p = 0.12). No additional vascular parameters were identified as predictive of ARE. There was a significant target volume threshold of 4 cm{sup 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

  11. Psychiatric drug-induced Chronic Brain Impairment (CBI): implications for long-term treatment with psychiatric medication.

    2011-01-01

    Understanding the hazards associated with long-term exposure to psychiatric drugs is very important but rarely emphasized in the scientific literature and clinical practice. Drawing on the scientific literature and clinical experience, the author describes the syndrome of Chronic Brain Impairment (CBI) which can be caused by any trauma to the brain including Traumatic Brain Injury (TBI), electroconvulsive therapy (ECT), and long-term exposure to psychiatric medications. Knowledge of the syndrome should enable clinicians to more easily identify long-term adverse effects caused by psychiatric drugs while enabling researchers to approach the problem with a more comprehensive understanding of the common elements of brain injury as they are manifested after long-term exposure to psychiatric medications. Treatment options are also discussed.

    Men with prostate cancer (PCa) frequently undergo androgen deprivation therapy (ADT), typically in the form of a depot injection of luteinizing hormone-releasing hormone agonists (LHRHa). LHRHa are associated with many adverse effects (eg, hot flashes, sexual dysfunction, loss of muscle mass, osteopenia, metabolic syndrome), which drastically impact patient quality of life. This literature review, which includes a comprehensive table documenting prevalence rates, provides a quick reference for health care professionals involved in the care of men undergoing ADT with LHRHa. Primary sources were acquired from PubMed using the search terms "androgen deprivation therapy" and each potentially adverse effect (eg, "androgen deprivation therapy and hot flashes"). Commonly cited review articles were also examined for citations of original studies containing prevalence rates. More than 270 articles were reviewed. In contrast to many existing reviews, rates are cited exclusively from original sources. The prevalence rates, obtained from original sources, suggest that more than half of documented adverse effects are experienced by as many as 40% or more of patients. A critique of the literature is also provided. Although there is a vast literature of both original and review articles on specific adverse effects of LHRHa, the quality of research on prevalence rates for some adverse effects is subpar. Many review articles contain inaccuracies and do not cite original sources. The table of prevalence rates will serve as a quick reference for health care providers when counseling patients and will aid in the development of evidence-based patient education materials.

    SALAWU, Emmanuel O

    2010-01-01

    Background: Lead is known for its adverse effects on various organs and systems. In this study, the ability of lead to adversely affect blood parameters was investigated, and Lycopersicon esculentum, or commonly known as tomato (a source of antioxidants), was administered orally in the form of tomato paste (TP) to reduce the adverse effects of lead. Methods: The study involved 56 Wistar rats divided equally into 4 groups of 14 rats each: Control, LAG, TPG, and LA+TPG. Control and TPG rats were given distilled water ad libitum, while LAG and LA+TPG rats were given 1% lead (II) acetate (LA) per day. TPG and LA+TPG rats were additionally treated with 1.5 ml of TP per day. All treatments lasted for 10 weeks, after which the rats were weighed and sacrificed, and haematological and biochemical parameters were measured. The independent samples t test was used to analyse the results. Results: Lead caused significant reductions in the following parameters: weight; packed cell volume; red blood cell and white blood cell counts; the percentages of lymphocytes and monocytes; total serum protein, albumin, and globulin levels; and plasma superoxide dismutase and catalase activities. In contrast, lead caused a significant increase in the percentage of neutrophils and the plasma malondialdehyde concentration. TP, however, significantly prevented the adverse effects of LA. Conclusion: The oral administration of TP prevents the adverse effects of lead on blood constituents. PMID:22135544

    The ultimate goal of cancer chemotherapy is to achieve a cure without causing any adverse effects. We have developed a pH-sensitive redox nanoparticle (RNP(N)), which disintegrates under acidic conditions and exposes nitroxide radicals, leading to strongly scavenging reactive oxygen species (ROS). After intravenous administration of RNP(N) to tumor bearing mice, it effectively accumulated in tumors due to the leaky neovascular and immature lymphatic system and scavenged ROS, resulting in suppression of inflammation and activation of NF-кB, after disintegration of RNP(N) in the tumors. Pre-administration of RNP(N) prior to treatments with anticancer agents, doxorubicin, to tumor-bearing mice significantly suppressed the progression of tumor size, compared to low-molecular weight 4-hydroxy-TEMPO. Interestingly, the administration of RNP(N) suppressed adverse effects of doxorubicin to normal organs due to the scavenging ROS and suppression of inflammation, which was confirmed by reduction in lactate dehydrogenase and creatine phosphokinase activities in plasma. RNP(N) is thus anticipated as a novel and ideal adjuvant for cancer chemotherapy.

    This work aimed at determining the local prevalence of adverse effects on women with CaCu that recieved LDR brachytherapy treatment at CECAN. The data was extracted from the patient's and medical physics' departement records. Non Gaussian statistics was used due to dose distribution characteristics. A total of 103 patients were studied with average age of 55{+-}13 years and Ia-IV FIGO clinical clasification. The observed prevalence is higher than that reported by other studies. It was observed that patients with proctitis were prescribed a slightly higher dose than those without adverse effects (90% confidence). Patients with proctitis also presented higher age (95% confidence) when compared with the mean of the studied population. The inverse applies to the group with other adverse effects, its average age is lower than the mean (90% confidence).

  16. A review of the adverse effects and safety of noradrenergic antidepressants.

    PubMed

    Whiskey, Eromona; Taylor, David

    2013-08-01

    There are a variety of noradrenergic antidepressants available, most of which act by inhibiting neuronal noradrenaline re-uptake, although few drugs are specific for this action. Where drugs have numerous actions the adverse effects of noradrenaline reuptake may be difficult to isolate, although in this respect the adverse effects of reboxetine, a specific noradrenaline re-uptake inhibitor, are illuminating. Noradrenergic antidepressants typically cause minor changes in blood and heart rate, sweating and insomnia. Other pharmacological actions shown by non-specific antidepressants may act to worsen or mitigate these adverse effects. Noradrenergic drugs are less likely than selective serotonin reuptake inhibitors (SSRIs) to cause sexual dysfunction but more likely to cause urinary hesitancy. Doubts remain over the relative propensity for antidepressants with different modes of action to cause diabetes and hyponatraemia. Noradrenergic actions do not seem to confer a risk of death in overdose.

  17. Psychiatric Emergencies

    PubMed Central

    Bayrakal, Sadi

    1972-01-01

    Dr. Bayrakal believes that the time has come for the family physician to deal with minor psychiatric disturbances in his office as well as psychiatric emergencies in the emergency department. The newly emerging medico-social philosophy of both the federal and provincial governments, he says, is giving greater responsibility and authority to the family physician in every area of medicine, including psychiatry. The author discusses major psychiatric emergencies (suicide, suicidal attempt, homicide, social scandal, as well as other psychiatric emergencies) on the ward including adolescent psychiatry. (The descriptions and treatment procedures are given on a concrete clinical level without theoretical overload.) In the family physician's work, psychological understanding is of profound importance. Giving him the added scope of psychiatric consideration to see the patient in bio-psycho-social totality will enable him to practice a more humanized form of medicine. PMID:20468779

  18. The effect of songwriting on knowledge of coping skills and working alliance in psychiatric patients: a randomized clinical effectiveness study.

    PubMed

    Silverman, Michael J

    2011-01-01

    The purpose of this study was to determine the effects of a songwriting intervention on psychiatric patients' knowledge of coping skills and working alliance. Participants were randomly assigned to scripted and manualized experimental (n=48) or control (n=41) conditions. The experimental condition was a group psychoeducational music therapy songwriting session concerning coping skills while the control condition was a group psychoeducational session concerning coping skills. Both conditions were single-session therapy with patients on an acute adult psychiatric unit. Results indicated no significant between group differences in measures of knowledge of coping skills, consumer working alliance, or perception of enjoyment (p>.05), although the experimental condition tended to have slightly higher mean scores than the control group for these measures. There was a significant between group difference in measures of therapist working alliance (p<.001), with the therapist scoring the experimental group higher than the control group. Although the music therapy group had a higher mean rate of previous psychiatric hospitalizations, their perception of enjoyment scores were still higher than those of the control condition, a finding incongruent in the literature. Furthermore, despite the increased number of previous hospitalizations, the music therapy condition had higher attendance rates than the control condition, thus possibly providing incentives for funding. It seems that group songwriting about coping skills can be as effective a psychosocial intervention as traditional talk-based psychoeducation to teach psychiatric inpatients how to proactively manage their illness. Additionally, music therapy can be as effective as talk-based psychoeducation in establishing working alliance. Implications for clinical practice, limitations, and suggestions for future research are provided.

    Weight loss reduces many of the health hazards associated with obesity including insulin resistance, diabetes mellitus, hypertension, dyslipidemia, sleep apnea, hypoxemia and hypercarbia, and osteoarthritis. Potential adverse effects of weight loss include a greater risk for gallstone formation and cholecystitis, excessive loss of lean body mass, water and electrolyte problems, mild liver dysfunction, and elevated uric acid levels. Less consequential problems such as diarrhea, constipation, hair loss, and cold intolerance may also occur. The short-term adverse effects are not severe enough to contraindicate weight loss, nor do they outweigh its short-term benefits.

    2015-03-30

    The objective of the present research was to test the hypotheses that: (1) Iraq/Afghanistan war veterans experience a wide range of psychiatric symptomatology (e.g., obsessive-compulsive symptoms, hypochondriasis, somatization); and (2) general psychiatric symptomatology among Iraq/Afghanistan war veterans is associated with their warzone experiences. To achieve this objective, Iraq/Afghanistan war veterans (N=155) completed a screening questionnaire that assessed a wide range of psychiatric symptoms along with a measure of warzone experiences. As expected, returning veterans reported significant elevations across a wide range of clinical scales. Approximately three-fourths screened positive on at least one clinical subscale, and a one-third screened positive on five or more. In addition, nearly all of these conditions were associated with veterans' warzone experiences (average r=0.36); however, this association was much stronger among veterans with posttraumatic stress disorder (PTSD) (average r=0.33) than among veterans without PTSD (average r=0.15). We also observed that approximately 18% of the variance in total psychiatric symptomatology was attributable to warzone experiences above and beyond the effects of childhood trauma and demographic factors. Taken together, these findings suggest that returning veterans experience a broad array of psychiatric symptoms that are strongly associated with their warzone experiences.

    2017-01-01

    Finasteride has proved to be relatively safe and effective in the therapeutic management of male androgenic alopecia. However, literature data report several endocrine imbalances inducing various adverse effects, which often persist after treatment cessation in the form of post-finasteride syndrome. Here we present the case of a 52-year-old man receiving finasteride (1 mg/day) who developed an uncommon adverse effect represented by generalized vitiligo 2 months after finasteride discontinuation. Associated adverse effects encountered were represented by mild sexual dysfunction (as determined by the International Index of Erectile Function, IIEF) and moderate depressive symptoms (according to DSM-V criteria), all of these manifestations aggregating within/as a possible post-finasteride syndrome. Further studies should develop and compare several therapeutic approaches, taking into account not only compounds that decrease the circulating dihydrotestosterone level but also those that could block the dihydrotestosterone receptors (if possible, compounds with selective tropism towards the skin). In addition, the possibility of predicting adverse effects of finasteride (according to hand preference and sexual orientation) should be taken into account.

    2014-08-01

    A tabletop simulation was developed as a patient safety activity that involved checking in a patient admitted to a psychiatric care unit. Students were second-degree (n = 79) and traditional (n = 53) BSN students. They were given suitcases or backpacks containing various items, and following a fictional hospital policy, they had to decide whether to give the items to the patient, place them in a secured area, or send them to the pharmacy or security personnel. The activity was evaluated using the Simulation Effectiveness Tool (SET) and two open-ended questions. Students reported that they found the simulation to be enjoyable and a good learning experience. Checking in a patient's belongings is not an activity students typically perform, but the simulation can help prepare them for situations they will experience in the workplace. This inexpensive activity can easily be adapted for staff orientation and competencies. [Journal of Psychosocial Nursing and Mental Health Services, 52(8), 39-44.].

  7. Synergistic childhood adversities and complex adult psychopathology.

    Putnam, Karen T; Harris, William W; Putnam, Frank W

    2013-08-01

    Numerous studies find a cumulative effect of different types of childhood adversities on increasing risk for serious adult mental and medical outcomes. This study uses the National Comorbidity Survey-Replication sample to investigate the cumulative impact of 8 childhood adversities on complex adult psychopathology as indexed by (a) number of lifetime diagnoses according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed., DSM-IV; American Psychiatric Association, 1994); (b) number of 4 DSM-IV disorder categories (mood, anxiety, impulse control, and substance abuse disorders); and (c) coexistence of internalizing and externalizing disorders. Seven of the 8 childhood adversities were significantly associated with complex adult psychopathology. Individuals with 4 or more childhood adversities had an odds ratio of 7.3, 95% confidence interval [4.7, 11.7] for 4 disorder categories. Additive and multiplicative synergistic effects increasing adult psychopathology were found for specific pairwise combinations of childhood adversities. Synergistic patterns differed by gender suggesting that women are more impacted by sexual abuse and men by economic hardship. The absence of childhood adversities was protective, in that it significantly decreased an individual's risk for subsequent adult mental illness. The results support the clinical impression that increased childhood adversity is associated with more complex adult psychopathology.

  8. The Role of Mindfulness in Reducing the Adverse Effects of Childhood Stress and Trauma

    2017-01-01

    Research suggests that many children are exposed to adverse experiences in childhood. Such adverse childhood exposures may result in stress and trauma, which are associated with increased morbidity and mortality into adulthood. In general populations and trauma-exposed adults, mindfulness interventions have demonstrated reduced depression and anxiety, reduced trauma-related symptoms, enhanced coping and mood, and improved quality of life. Studies in children and youth also demonstrate that mindfulness interventions improve mental, behavioral, and physical outcomes. Taken together, this research suggests that high-quality, structured mindfulness instruction may mitigate the negative effects of stress and trauma related to adverse childhood exposures, improving short- and long-term outcomes, and potentially reducing poor health outcomes in adulthood. Future work is needed to optimize implementation of youth-based mindfulness programs and to study long-term outcomes into adulthood. PMID:28264496

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

    PubMed Central

    Croft, Ashley M; Herxheimer, Andrew

    2002-01-01

    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. PMID:11914150

    Purpose: The development of adverse effects resulting from the radiotherapy of cancer limits the use of this treatment modality. The validation of a test capable of predicting which patients would be most likely to develop adverse responses to radiation treatment, based on the possession of specific genetic variants, would therefore be of value. The purpose of the Genetic Predictors of Adverse Radiotherapy Effects (Gene-PARE) project is to help achieve this goal. Methods and Materials: A continuously expanding biorepository has been created consisting of frozen lymphocytes and DNA isolated from patients treated with radiotherapy. In conjunction with this biorepository, a database is maintained with detailed clinical information pertaining to diagnosis, treatment, and outcome. The DNA samples are screened using denaturing high performance liquid chromatography (DHPLC) and the Surveyor nuclease assay for variants in ATM, TGFB1, XRCC1, XRCC3, SOD2, and hHR21. It is anticipated that additional genes that control the biologic response to radiation will be screened in future work. Results: Evidence has been obtained that possession of variants in genes, the products of which play a role in radiation response, is predictive for the development of adverse effects after radiotherapy. Conclusions: It is anticipated that the Gene-PARE project will yield information that will allow radiation oncologists to use genetic data to optimize treatment on an individual basis.

  3. Current research on the epidemiology, medical and psychiatric effects, and treatment of methamphetamine use

    PubMed Central

    Rawson, Richard A.

    2014-01-01

    Methamphetamine (MA) is a drug that is widely used in many parts of the world. It has multiple neurobiological impacts on the nervous system, some of which are transitory and some more long lasting. MA activates the reward system of the brain and produces effects that are highly reinforcing, which can lead to abuse and dependence. Routes of administration that produce rapid onset of the drug’s effects (i.e., smoking and injection) are likely to lead to more rapid addiction and more medical and psychiatric effects. The medical effects of MA use are extensive, and chronic use of MA can produce significant neurological damage as well as damage to cardiovascular, pulmonary, and other organ systems. Both acute and chronic MA use can lead to extreme paranoia, anxiety, and depression, and following discontinuation of MA use, cognitive deficits and anhedonia can persist for months. No effective pharmacotherapies have been developed for the treatment of MA dependence, although this is an area of very active research. Several behavioral treatments have been shown to reduce MA use, but better treatments are needed. The research agenda for MA is substantial, with development of effective pharmacotherapies as one of the most important priorities. PMID:25214749

    Background Methamphetamine (MA) which is known as “shisheh” in Iran is a drug that widely is used in many parts of the world and it is near to a decade that is available for the most drug users and has a considerable prevalence of use. Due to high abuse prevalence and very new challenging phenomenon, it is very important that researchers and treatment providers become more familiar with different aspects of MA. Discussion It has multiple neurobiological impacts on the nervous system, some of which are transitory and some longer lasting. MA activates the reward system of the brain and produces effects that are highly reinforcing, which can lead to abuse and dependence. Routes of administration that produce rapid onset of the drug’s effects (i.e., smoking and injection) are likely to lead to more rapid addiction and more medical and psychiatric effects. No effective pharmacotherapies have been developed for the treatment of MA dependence; although, this is an area of very active research. Several behavioral treatments have been shown to reduce MA use, but better treatments are needed. Conclusion Harm reduction strategies for non-treatment seeking MA users are needed to reduce the risk of human immunodeficiency virus and other medical risks. The research agenda for MA is substantial, with development of effective pharmacotherapies as one of the most important priorities. Appropriate and effective response for prevention, treatment and harm reduction services due to increasing problems regarding MA in Iran and some other countries in the region. PMID:25984282

    Trazodone is an antidepressant that is FDA-approved for the treatment of depression. It has been used by mental health and primary care providers for the treatment of multiple psychiatric and medical conditions .This review describes trazodone mechanism of action, formulation, dosage and adverse effects and then summarizes the beneficial effects of trazodone in the treatment of various psychiatric and medical conditions such as major depression, as well non-approved FDA indications such as insomnia,anxiety disorders, posttraumatic stress disorder, obsessive compulsive disorder, feeding and eating disorders, substance use disorders, behavioral disturbances associated with cognitive dysfunction, sexual dysfunction, certain pain conditions, and rehabilitation after acute ischemic stroke. Despite trazodone's favorable effects in the treatment of FDA-unapproved psychiatric and medical conditions, large, randomized controlled clinical trials are still needed to confirm its efficacy in the treatment of the multiple conditions for which it is often used in clinical practice.

    This cross-sectional study compared the effects of treatment with atypical antipsychotic drugs on quality of life (QoL) and side effects in 218 patients with schizophrenia attending the ambulatory services of psychiatric in Rio Grande do Norte, Brazil. Socio-economic variables were compared. The five-dimension EuroQoL (EQ-5D) was used to evaluate QoL, and side effects were assessed using the Udvalg for Kliniske Undersøgelser (UKU) Side Effect Rating Scale and the Simpson-Angus Scale. Data were analysed using the χ (2) test and Student's t test, with a significance level of 5 %. Average monthly household incomes in the medication groups were 1.1-2.1 minimum wages ($339-$678). UKU Scale scores showed significant differences in side effects, mainly, clozapine, quetiapine and ziprasidone (p < 0.05). EQ-5D scores showed that all drugs except olanzapine significantly impacted mobility (p < 0.05), and proportions of individuals reporting problems in other dimensions were high: 63.6 % of clozapine users reported mobility problems, 63.7 and 56.3 % of clozapine and ziprasidone users, respectively, had difficulties with usual activities, 68.8 and 54.5 % of ziprasidone and clozapine users, respectively, experienced pain and/or discomfort, and 72.8 % of clozapine users reported anxiety and/or depression. Psychiatric, neurological, and autonomous adverse effects, as well as other side effects, were prevalent in users of atypical antipsychotic drugs, especially clozapine and ziprasidone. Olanzapine had the least side effects. QoL was impacted by side effects and economic conditions in all groups. Thus, the effects of these antipsychotic agents appear to have been masked by aggravating social and economic situations.

    This cross-sectional study aimed to compare the effects of treatment with an atypical antipsychotic drug (olanzapine or risperidone) on quality of life (QoL) and to document adverse effects in 115 patients diagnosed with schizophrenia who attended the ambulatory service of Hospital Dr. João Machado, Natal, Rio Grande do Norte, Brazil. Socioeconomic, sociodemographic, and clinical variables were compared. The QoL Scale validated for Brazil (QLS-BR) was used to evaluate QoL, and adverse effects were assessed using the Udvalg for Kliniske Undersøgelser Side Effect Rating Scale. Data were analyzed using the χ(2) test and Student's t test, with a significance level of 5 %. Patients in both drug groups showed severe impairment in the occupational domain of the QLS-BR. Global QLS-BR scores indicated impairment among risperidone users and severe impairment among olanzapine users. The most significant side effects were associated with risperidone, including asthenia/lassitude/fatigue, somnolence/sedation, paresthesia, change in visual accommodation, increased salivation, diarrhea, orthostatic posture, palpitations/tachycardia, erythema, photosensitivity, weight loss, galactorrhea, decreased sexual desire, erectile/orgasmic dysfunction, vaginal dryness, headache, and physical dependence. QoL was impaired in patients using olanzapine and in those using risperidone. Risperidone use was associated with psychic, neurological, and autonomous adverse effects and other side effects.

    The exposome encompasses an individual's exposure to exogenous chemicals, as well as endogenous chemicals that are produced or altered in response to external stressors. While the exposome concept has been established for human health, its principles can be extended to include broader ecological issues. The assessment of exposure is tightly interlinked with hazard assessment. Here, we explore if mechanistic understanding of the causal links between exposure and adverse effects on human health and the environment can be improved by integrating the exposome approach with the adverse outcome pathway (AOP) concept that structures and organizes the sequence of biological events from an initial molecular interaction of a chemical with a biological target to an adverse outcome. Complementing exposome research with the AOP concept may facilitate a mechanistic understanding of stress-induced adverse effects, examine the relative contributions from various components of the exposome, determine the primary risk drivers in complex mixtures, and promote an integrative assessment of chemical risks for both human and environmental health.

    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.

    Early identification of adverse effect of preclinical and commercial drugs is crucial in developing highly efficient therapeutics, since unexpected adverse drug effects account for one-third of all drug failures in drug development. To correlate protein–drug interactions at the molecule level with their clinical outcomes at the organism level, we have developed an integrated approach to studying protein–ligand interactions on a structural proteome-wide scale by combining protein functional site similarity search, small molecule screening, and protein–ligand binding affinity profile analysis. By applying this methodology, we have elucidated a possible molecular mechanism for the previously observed, but molecularly uncharacterized, side effect of selective estrogen receptor modulators (SERMs). The side effect involves the inhibition of the Sacroplasmic Reticulum Ca2+ ion channel ATPase protein (SERCA) transmembrane domain. The prediction provides molecular insight into reducing the adverse effect of SERMs and is supported by clinical and in vitro observations. The strategy used in this case study is being applied to discover off-targets for other commercially available pharmaceuticals. The process can be included in a drug discovery pipeline in an effort to optimize drug leads and reduce unwanted side effects. PMID:18052534

    Deep brain stimulation is an established neurosurgical therapy for movement disorders including essential tremor and Parkinson’s disease. While typically highly effective, deep brain stimulation can sometimes yield suboptimal therapeutic benefit and can cause adverse effects. In this study, we tested the hypothesis that intraoperative functional magnetic resonance imaging could be used to detect deep brain stimulation-evoked changes in functional and effective connectivity that would correlate with the therapeutic and adverse effects of stimulation. Ten patients receiving deep brain stimulation of the ventralis intermedius thalamic nucleus for essential tremor underwent functional magnetic resonance imaging during stimulation applied at a series of stimulation localizations, followed by evaluation of deep brain stimulation-evoked therapeutic and adverse effects. Correlations between the therapeutic effectiveness of deep brain stimulation (3 months postoperatively) and deep brain stimulation-evoked changes in functional and effective connectivity were assessed using region of interest-based correlation analysis and dynamic causal modelling, respectively. Further, we investigated whether brain regions might exist in which activation resulting from deep brain stimulation might correlate with the presence of paraesthesias, the most common deep brain stimulation-evoked adverse effect. Thalamic deep brain stimulation resulted in activation within established nodes of the tremor circuit: sensorimotor cortex, thalamus, contralateral cerebellar cortex and deep cerebellar nuclei (FDR q < 0.05). Stimulation-evoked activation in all these regions of interest, as well as activation within the supplementary motor area, brainstem, and inferior frontal gyrus, exhibited significant correlations with the long-term therapeutic effectiveness of deep brain stimulation (P < 0.05), with the strongest correlation (P < 0.001) observed within the contralateral cerebellum.

    Corresponding to the uncontrolled diabetes pandemic, significant effort has been invested in developing new therapeutic options. Nevertheless, all medicines have possible adverse effects. Recently, a trend of 'scrutinizing' novel hypoglycaemic drug side effects based on scant scientific data has emerged. With recent publications highlighting possible dangers of rosiglitazone, insulin glargine, sitagliptin, exenatide and, most recently, pioglitazone, it seems that all means are valid and that every database is suitable, even if specifically defined as inadequate for the purpose of data analysis. The use of such data may lead authors to draw erroneous conclusions that may be granted unwarranted impact upon publication in leading scientific journals and eventually lead patients and misinformed physicians to wrongly change beneficial medication regimes. Adherence to strict scientific methodology, ongoing large clinical trials and creating adjudicated patient databases may facilitate early recognition of adverse effects while avoiding disruptive false alarms.

  13. Mining multi-item drug adverse effect associations in spontaneous reporting systems

    PubMed Central

    2010-01-01

    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. PMID:21044365

    The aim of this study was to evaluate adverse effects of multi-walled carbon nanotubes (MWCNT) produced for industrial purposes, on the human epithelial cell line A549. MWCNT were dispersed in dipalmitoyl lecithin (DPL), a component of pulmonary surfactant, and the effects of dispersion in DPL were compared to those in 2 other media: ethanol (EtOH) and phosphate buffer saline (PBS). Effects of MWCNT were also compared to those of 2 asbestos fibers (chrysotile and crocidolite) and carbon black (CB) nanoparticles, not only in A549 cells, but also on mesothelial cells (MeT5A human cell line), used as an asbestos-sensitive cell type. MWCNT formed agglomerates on top of both cell lines (surface area 15–35 μm2), that were significantly larger and more numerous in PBS than in EtOH and DPL. Whatever the dispersion media, incubation with 100 μg/ml MWCNT induced a similar decrease in metabolic activity without changing cell membrane permeability or apoptosis. Neither MWCNT cellular internalization nor oxidative stress were observed. In contrast, asbestos fibers penetrated into the cells, decreased metabolic activity but not cell membrane permeability and increased apoptosis, without decreasing cell number. CB was internalized without any adverse effects. In conclusion, this study demonstrates that MWCNT produced for industrial purposes exert adverse effects without being internalized by human epithelial and mesothelial pulmonary cell lines.

    BACKGROUND—The adverse effects of oral corticosteroids are widely recognised but there are few quantitative data on which to base advice to patients. In a two part cross sectional study we compared adverse effects in patients with lung disease taking oral corticosteroids and control subjects and related the adverse effects to corticosteroid dose in the patient group.
METHODS—Data on oral corticosteroid use, lifestyle, fractures, and other possible adverse effects were collected by questionnaire and compared between a community based cohort of patients taking continuous or frequent intermittent oral corticosteroids for asthma, chronic obstructive pulmonary disease, or alveolitis and age and sex matched control subjects. Dose related effects were explored in the corticosteroid group using cumulative dose quartiles and multiple logistic regression.
RESULTS—A total of 367 patients (⩾50 years, 48% female) and 734 control subjects completed the questionnaire. The cumulative incidence of fractures since the time of diagnosis was 23% for patients taking oral corticosteroids and 15% in the control group (odds ratio (OR) 1.8; 95% confidence interval (CI) 1.3 to 2.6). Patients were more likely to have had a fracture of the vertebrae (OR 10; 95% CI 2.9 to 34), hip (OR 6; 95% CI 1.2 to 30), and ribs or sternum (OR 3.2, 95% CI 1.6 to 6.6) than control subjects. They also reported a significant increase in cataracts, use of antacids, muscle weakness, back pain, bruising, oral candidiasis, and having fewer teeth. The effects of oral corticosteroids were dose related: the odds ratio for patients in the highest compared with the lowest cumulative dose quartile (median prednisolone dose 61 g versus 5 g) ranged from 2 for all fractures to 9 for vertebral fractures and bruising.
CONCLUSIONS—By quantifying the morbidity associated with the use of oral corticosteroids, this study should help to rationalise their long term use.

    Little is known about the relationships between adverse health effects and unhealthy behaviors among medical students using Facebook. The aim of this study was to determine the associations between adverse health effects and unhealthy behaviors with Facebook use. A cross-sectional study was conducted in a private university in Malaysia among 316 medical students. A self-administered questionnaire was used. It included questions on sociodemographics, pattern of Facebook use, social relationship, unhealthy behaviors, and health effects. Mean age was 20.5 (±2.7) years. All students had a Facebook account. The average daily Facebook surfing hours were 2.5 (±1.7). Significant associations were found between average hours of Facebook surfing and the following factors: isolation from family members and community, refusing to answer calls, musculoskeletal pain, headache, and eye irritation (P < 0.005). The average hours spent on Facebook were significantly associated with holding urination and defecation while online, surfing Facebook until midnight, and postponing, forgetting, or skipping meals (P < 0.005). The average hours spent on Facebook were associated with adverse health effects and unhealthy behaviors among medical students, as well as social isolation from the family and community.

    Oseltamivir is the most widely used antiviral drug for the treatment and prophylaxis of influenza. However, not much is known about its adverse effects. The potential side effects were investigated in male and female rats (140-170 g). Oseltamivir was administered at 2.2 mg·kg(-1)·day(-1) for 5 days. For both genders, treatment with oseltamivir resulted in significant reductions in the hepatic activities of glutathione reductase, glutathione peroxidase, and glutathione S-transferase. Also for both genders, oseltamivir produced modest reductions in the hepatic activities of UDP-glucuronosyltransferase, quinone oxidoreductase, thioredoxin reductase, CYP1A1/2, and CYP3A, as well as hepatic glutathione content. For both genders, neither the kidney functions nor protein profile was affected by oseltamivir. Oseltamivir also caused significant elevation in serum levels of both triacylglycerols and LDL-cholesterol and in the activity of γ-glutamyl transpeptidase, in both genders. For male animals only, oseltamivir treatment elevated the serum level of total cholesterol as well as the activity of serum alanine aminotransferase, and reduced the hepatic activities of superoxide dismutase and catalase. Oseltamivir caused oxidative stress and acute toxicity in the liver, and disrupted the cholesterol and lipid metabolism but was less likely to cause serious drug interactions. There was a sexual differentiation in these adverse effects, with adverse effects being more evident in male rats.

  19. Evidence for adverse effect of perinatal glucocorticoid use on the developing brain

    PubMed Central

    2014-01-01

    The use of glucocorticoids (GCs) in the perinatal period is suspected of being associated with adverse effects on long-term neurodevelopmental outcomes for preterm infants. Repeated administration of antenatal GCs to mothers at risk of preterm birth may adversely affect fetal growth and head circumference. Fetal exposure to excess GCs during critical periods of brain development may profoundly modify the limbic system (primarily the hippocampus), resulting in long-term effects on cognition, behavior, memory, co-ordination of the autonomic nervous system, and regulation of the endocrine system later in adult life. Postnatal GC treatment for chronic lung disease in premature infants, particularly involving the use of dexamethasone, has been shown to induce neurodevelopmental impairment and increases the risk of cerebral palsy. In contrast to studies involving postnatal dexamethasone, long-term follow-up studies for hydrocortisone therapy have not revealed adverse effects on neurodevelopmental outcomes. In experimental studies on animals, GCs has been shown to impair neurogenesis, and induce neuronal apoptosis in the immature brains of newborn animals. A recent study has demonstrated that dexamethasone-induced hypomyelination may result from the apoptotic degeneration of oligodendrocyte progenitors in the immature brain. Thus, based on clinical and experimental studies, there is enough evidence to advice caution regarding the use of GCs in the perinatal period; and moreover, the potential long-term effects of GCs on brain development need to be determined.

    2015-03-01

    Cannabis use is associated with an increased risk of psychosis in vulnerable individuals. Cannabis containing high levels of the partial cannabinoid receptor subtype 1 (CB1) agonist tetrahydrocannabinol (THC) is associated with the induction of psychosis in susceptible subjects and with the development of schizophrenia, whereas the use of cannabis variants with relatively high levels of cannabidiol (CBD) is associated with fewer psychotic experiences. Synthetic cannabinoid receptor agonists (SCRAs) are full agonists and often more potent than THC. Moreover, in contrast to natural cannabis, SCRAs preparations contain no CBD so that these drugs may have a higher psychosis-inducing potential than cannabis. This paper reviews the general toxicity profile and the adverse effects of SCRAs with special emphasis on their psychosis-inducing risk. The review shows that, compared with the use of natural cannabis, the use of SCRAs may cause more frequent and more severe unwanted negative effects, especially in younger, inexperienced users. Psychosis and psychosis-like conditions seem to occur relatively often following the use of SCRAs, presumably due to their high potency and the absence of CBD in the preparations. Studies on the relative risk of SCRAs compared with natural cannabis to induce or evoke psychosis are urgently needed.

    Objectives To determine rates and risk factors for adverse outcomes in patients discharged from forensic psychiatric services. Method We conducted a historical cohort study of all 6,520 psychiatric patients discharged from forensic psychiatric hospitals between 1973 and 2009 in Sweden. We calculated hazard ratios for mortality, rehospitalisation, and violent crime using Cox regression to investigate the effect of different psychiatric diagnoses and two comorbidities (personality or substance use disorder) on outcomes. Results Over mean follow-up of 15.6 years, 30% of patients died (n = 1,949) after discharge with an average age at death of 52 years. Over two-thirds were rehospitalised (n = 4,472, 69%), and 40% violently offended after discharge (n = 2,613) with a mean time to violent crime of 4.2 years. The association between psychiatric diagnosis and outcome varied—substance use disorder as a primary diagnosis was associated with highest risk of mortality and rehospitalisation, and personality disorder was linked with the highest risk of violent offending. Furthermore comorbid substance use disorder typically increased risk of adverse outcomes. Conclusion Violent offending, premature mortality and rehospitalisation are prevalent in patients discharged from forensic psychiatric hospitals. Individualised treatment plans for such patients should take into account primary and comorbid psychiatric diagnoses. PMID:27196309

    2013-06-01

    Penicillamine is a well-known heavy metal chelator, classically used in the treatment of Wilson disease, rheumatoid arthritis, and cystinuria. From a dermatologic standpoint, penicillamine was found to be useful in the treatment of systemic sclerosis. The successful therapeutic uses of penicillamine have been hindered by its numerous adverse effects, both cutaneous and extra-cutaneous. It is a unique drug since it provokes a diversity of dermatologic manifestations that include (1) acute hypersensitivity reactions, (2) dermopathies characterized by elastic fiber abnormalities including elastosis perforans serpiginosa and pseudo-pseudoxanthoma elasticum, (3) autoimmune disorders such as pemphigus and penicillamine-induced lupus erythematosus-like syndrome, and (4) miscellaneous dermatoses that result from undefined mechanisms. These cutaneous adverse effects may correlate with the dosage and duration of penicillamine therapy as well as the disease being treated.

    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.

    Although many studies have addressed adverse outcomes in children of parents with alcohol abuse/dependence, less is known about the possible long-term effects of more normative patterns of parental alcohol consumption, including drinking at lower risk levels and heavy episodic or binge drinking. The extent of harm from parental drinking may therefore be underestimated. With this research proposal, we describe a project that aims to assess possible long-term adverse effects of parental drinking by combining survey and nationwide registry data. Advantages of a longitudinal general population cohort design include that it allows for detailed information on parental drinking through survey data and identification of possible negative long-term health and social outcomes from exposure to parental drinking 1–19 years after exposure through continuously updated nationwide registers. The rich information available from combining survey and registry data allows us to take into account important confounders, mediators, and moderators. PMID:26688663

    The authors report the efficacy and adverse effects of intranasal ethmoidectomy in 70 patients with asthma and persistent severe symptoms from nasosinal polyposis despite repeated prior treatment. The efficacy was defined according to the evolution of symptoms and endoscopic findings. Adverse effects were evaluated according to subjective clinical and therapeutic data in all 70 patients. In addition, 25 patients had complete pre and post-operative pulmonary function tests. The results confirm that intranasal micro-surgery does not increase the severity of asthma. On the other hand, no significant improvement in bronchial function was noted after ethmoidectomy. Finally, the authors emphasize the poorer results obtained in Widal's disease and the importance, after the failure of medical treatment, of using of sufficiently extensive surgical procedure in order to decrease the incidence of recurrences.

    Intrauterine growth restriction (IUGR) is associated with higher rates of fetal, perinatal, and neonatal morbidity and mortality. The consequences of IUGR include short-term metabolic, hematological and thermal disturbances that lead to metabolic syndrome in children and adults. Additionally, IUGR severely affects short- and long-term fetal brain development and brain function (including motor, cognitive and executive function) and neurobehavior, especially neuropsychology. This review details the adverse effects of IUGR on fetal brain development and discusses intervention strategies.

    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.

    Somnambulism (sleepwalking) is a disorder of arousal that falls under "parasomnia" group and is more common in children. These phenomena occur as primary sleep events or secondary to systemic disease or can be drug induced. Medications that can cause sleepwalking include neuroleptics, hypnotics, lithium, amitriptyline, and β-blockers. This report presents an unusual adverse effect of topiramate on sleep in a patient with migraine.

    Tooth bleaching (whitening) is one of the most common and inexpensive method for treating discolouration of teeth. Dental aesthetics, especially tooth colour, is of great importance to majority of the people; and discolouration of even a single tooth can negatively influence the quality of life. Therefore, a review of the literature was carried out (limited to aesthetic tooth-bleaching) to provide a broad overview of the efficacy and adverse effects of various tooth whitening products on soft and hard oral tissues.

    Study objective: To determine the effect of chronic job insecurity and changes in job security on self reported health, minor psychiatric morbidity, physiological measures, and health related behaviours. Design: Self reported health, minor psychiatric morbidity, physiological measures, and health related behaviours were determined in 931 women and 2429 men who responded to a question on job insecurity in 1995/96 and again in 1997/99. Self reported health status, clinical screening measures, and health related behaviours for participants whose job security had changed or who remained insecure were compared with those whose jobs had remained secure. Setting: Prospective cohort study, Whitehall II, all participants were white collar office workers in the British Civil Service on entry to the study. Main results: Self reported morbidity was higher among participants who lost job security. Among those who gained job security residual negative effects, particularly in the psychological sphere were observed. Those exposed to chronic job insecurity had the highest self reported morbidity. Changes in the physiological measures were limited to an increase in blood pressure among women who lost job security and a decrease in body mass index among women reporting chronic job insecurity. There were no significant differences between any of the groups for alcohol over the recommended limits or smoking. Conclusion: Loss of job security has adverse effects on self reported health and minor psychiatric morbidity, which are not completely reversed by removal of the threat and which tend to increase with chronic exposure to the stressor.

    Psychiatric rehabilitation (PR) is widely recognized as a treatment approach and an array of evidence-based practices effective for promoting the recovery of people with serious mental illness (SMI). However, its use in institutional settings is not widespread for unclear reasons. Policymakers may sometimes believe the superiority of PR in controlled research does not apply in the real world, for various reasons. This study exploits an unusual set of real-world circumstances surrounding the closure of a well-developed PR program in a state hospital. The program was closed after a period of mental-health services reform that significantly augmented the surrounding community-service system. The PR program was converted to conventional medical-institutional model-treatment units with no reduction in beds or funding within the state hospital. A database composed of public documents was used to analyze the consequences of the closing. Within the institution, the consequences included a persistent presence of long-term difficult-to-discharge patients, a slowed discharge rate, a net increase in the hospital's per capita treatment costs, and higher use of restraint/seclusion. Effects were also detectable in the surrounding mental-health service system, including degraded outcome of community-based step-down services and increased pressure on emergency/crisis services. The consequences of closing the program are consistent with expectations based on research, and demonstrate danger in assuming that real world exigencies obviate research findings.

    Our aim was to investigate the adverse effects of occupational exposure to trivalent chromium. We measured chromium and iron levels in serum and urine and hemoglobin levels in tannery workers and unexposed persons. We studied three groups of subjects. Group 1 included 15 non-smoking male tannery workers highly exposed to chromium from tanning and retanning departments. Group 2 included 14 non-smoking male tannery workers with moderate chromium exposure from dying, drying and finishing departments. Group 3 included 11 healthy, non-smoking male subjects without direct chromium exposure. Higher serum chromium levels were observed in groups 1 and 2 with respect to group 3 (mean values respectively: 0.43; 0.25 and 0.13 microg x l(-1)). Urine chromium levels in group 1 were higher than those in controls (mean values: 1.78 and 1.35 microg x l(-1)). In group 1 an inverse association was found between serum chromium and urine iron (-0.524), urine chromium and hemoglobin (-0.594) and between the urine chromium to iron ratio and hemoglobin (-0.693, p<0.05). The results suggest a chromium adverse effect on iron metabolism, possibly associated with excessive body chromium accumulation. In conclusion, chromium urine test could be recommended for diagnosis of chromium adverse effect on iron metabolism. Further studies are needed to quantify the relationship between urine chromium and hemoglobin metabolism.

    Regulatory agencies grant product licences (marketing authorizations) for medicinal products in the light of evidence that the balance between benefit and harm in the population is favourable. Here we consider a framework for allowing regulatory agencies to make rational decisions when reviewing product licences in the light of new information about harms that change that balance. The regulator can revoke the product licence, restrict the product's availability or change the 'label' in different ways. We examine the features of the adverse effect that may be relevant in making the decision: namely, individual differences in susceptibility; the possibility of monitoring; and the availability of protective strategies. The balance of benefit and harm, and the time-course and dose relation of the adverse effect play important roles in the decision-making process. We set out how these factors can help determine the logical response to new information on the balance between benefit and harm, and provide a series of relevant examples. We believe that when regulatory agencies have to decide how to amend the product licence of a drug when new serious adverse effects cause concern, they would find it useful to adopt a framework of this kind, using different strategies for different cases. Our proposed framework could also be useful in risk management planning during drug development.

    The treatment of thyroid cancer has promising prospects, mostly through the use of surgical or radioactive iodine therapy. However, some thyroid cancers, such as progressive radioactive iodine-refractory differentiated thyroid carcinoma, are not remediable with conventional types of treatment. In these cases, a treatment regimen with multi-kinase inhibitors is advisable. Unfortunately, clinical trials have shown a large number of patients, treated with multi-kinase inhibitors, being adversely affected by hypertension. This means that treatment of thyroid cancer with multi-kinase inhibitors prolongs progression-free and overall survival of patients, but a large number of patients experience hypertension as an adverse effect of the treatment. Whether the prolonged lifetime is sufficient to develop sequelae from hypertension is unclear, but late-stage cancer patients often have additional diseases, which can be complicated by the presence of hypertension. Since the exact mechanisms of the rise of hypertension in these patients are still unknown, the only available strategy is treating the symptoms. More studies determining the pathogenesis of hypertension as a side effect to cancer treatment as well as outcomes of dose management of cancer drugs are necessary to improve future therapy options for hypertension as an adverse effect to cancer therapy with multi-kinase inhibitors.

    OBJECTIVES: To re-examine a health-protective role of the common Apolipoprotein E (APOE) polymorphism focusing on connections between the APOE ε2-containing genotypes and impairments in instrumental activities of daily living [IADL] in older (65+) males and females. To examine how these connections may be mediated by diagnosed coronary heart disease (CHD), Alzheimer's disease, colorectal cancer, macular degeneration (MD), and atherosclerosis. DESIGN: Retrospective cross-sectional study. SETTING: The unique disability-focused data from a genetic sub-sample of the 1999 National Long Term Care Survey linked with Medicare service use files. PARTICIPANTS: 1733 genotyped individuals interviewed on IADL disabilities. MEASUREMENTS: Indicators of IADL impairments, five geriatric disorders, and ε2-containing genotypes. RESULTS: The ε2/3 genotype is a major contributor to adverse associations between the ε2 allele and IADL disability in males [Odds Ratio (OR)=3.09, Confidence Interval (CI)=1.53-6.26)]. It shows, however, significant protective effects for CHD (OR=0.55, CI=0.33-0.92), while CHD is adversely associated with IADL disability (OR=2.18, CI=1.28-3.72). The presence of five diseases does not significantly alter the adverse association between ε2-containing genotypes and disability. Protective effects of the ε2/3 genotype for CHD (OR=0.52, CI=0.27-0.99) and deleterious effects for IADL (OR=3.50, CI=1.71-7.14) for males hold in multivariate models with both these factors included. No significant associations between the ε2-containing genotypes and IADL are found in females. CONCLUSIONS: The ε2 allele can play a dual role in males, protecting them against some health disorders, while promoting others. Strong adverse relationships with disability suggest that ε2-containing genotypes can be unfavorable factors for the health/well-being of aging males. PMID:18179501

    Six second-generation antipsychotics (SGAs), aripiprazole, clozapine, olanzapine, quetiapine, risperidone and ziprasidone, are currently US FDA approved. The aim of this review is to investigate whether sex differences exist for efficacy and adverse effects of these drugs.Sex-related differences have been shown in the pharmacokinetics of cytochrome P450 (CYP), with a higher activity in females for CYP3A4 and CYP2D6. However, even if there are pharmacokinetic differences between females and males, significantly higher plasma concentrations in women have been demonstrated only for olanzapine and clozapine. To date, sex differences in adverse effects have not been well studied, but some adverse effects such as weight gain, hyperprolactinaemia and cardiac effects are reported to be particularly problematic for women. Most of the studies reviewed indicate that clozapine and olanzapine are associated with greater bodyweight gain than the other atypical antipsychotics, and that serious adverse effects such as metabolic syndrome, which includes increased visceral adiposity, hyperglycaemia, hypertension and dyslipidaemia induced by SGAs, are more frequent in females. According to most studies, the risk for cardiac adverse effects induced by SGAs is the same in male and female patients. Although women are at a lower risk of sudden cardiac death, they have a higher risk of induced long QT syndrome from antiarrhythmic and, probably, antipsychotic drugs. The propensity of sexual dysfunctions is higher with conventional antipsychotics than with SGAs. Additionally, there is some evidence that female sexual dysfunction is associated with high prolactin levels; however, whether the degree of prolactin level elevation is different between female and male patients remains controversial. There is no evidence for sex differences for any of the SGAs to cause a higher rate of extrapyramidal symptoms, acute dystonia or any other movement disturbance. Knowledge of the risks and benefits

    Limited pharmacokinetic and safety data exist for MMF in pediatric HTR. Previously targeted MPA-TL are 1.5-3.0 μg/mL. The objective of this study was to assess the outcomes targeting MPA-TL of 0.8-2.0 μg/mL in pediatric HTR. MPA-TL were retrospectively collected 2-12 months post-transplant. Acute rejection, infection, leukopenia, and GI complaints were then correlated with MPA-TL. A total of 355 MPA-TL from 22 HTR were included. Median age was 2.5 yr. Primary indication for transplant was dilated cardiomyopathy (64%). Mean MPA-TL was 1.7 ± 0.9 μg/mL. African American patients received significantly higher doses (702 ± 235 mg/m(2) ) compared with other races (p = 0.035). Leukopenia was less common in patients with SUB MPA vs. others (p = 0.01). MMF was discontinued for GI complaints in one patient and leukopenia in two patients. One SUB patient had acute rejection, and one SUP patient had infection. One-yr survival was 100%. Targeting a lower range for MPA-TL was not associated with significant rejection or infection. Despite lower MPA-TL, MMF was discontinued in 3/22 patients for adverse effects.

    Objective Depression and anxiety are common disorders in inflammatory bowel disease (IBD). Our aim is to prospectively determine the effect of psychiatric treatment on scores for depression, anxiety, quality of life (QoL), and sexual dysfunction in an outpatient population diagnosed with IBD and also anxiety and/or depression disorder. Patients and methods Patients who scored higher than the cutoff point on the Hospital Anxiety Depression Scale were referred for further structured psychiatric evaluation and determination of the need for psychiatric drug treatment. Patients who underwent drug therapy completed Short Form-36 (SF-36) and the Arizona Sexual Experience Scale at baseline and after 6 months of follow-up. Results Major depressive disorder and generalized anxiety disorder were the most common diagnoses. After 6 months, 47 patients had completely adhered to drug treatment (group A), whereas 20 were nonadherent (group B). In group A, all domains of SF-36, Arizona Sexual Experience Scale, depression/anxiety scores, and Crohn’s disease activity index were statistically improved after treatment when compared with the baseline. In group B, the three domains of SF-36, platelet count, and mean corpuscular volume were worse between baseline and at 6 months. Conclusion In IBD patients having any psychiatric disorder, 6 months of antidepressant drug treatment is associated with an improvement in depression, anxiety, QoL, and sexual functioning scores, as well as an improvement in Crohn’s disease activity index. On the other hand, insufficient psychiatric treatment seems to be related to a poor QoL. PMID:27069364

    High-dose opioid administration is associated with significant adverse events. Evidence suggests that low-dose ketamine infusions improve perioperative analgesia over conventional opioid management, but usage is highly variable. Ketamine's adverse drug effects (ADEs) are well known, but their prevalence during low-dose infusions in a clinical setting and how often they lead to infusion discontinuation are unknown. The purposes of this study were 3-fold: (1) to identify patient factors associated with initiation of ketamine infusions during spine surgery, (2) to identify specific spine procedures in which ketamine has been used most frequently, and (3) to identify ADEs associated with postoperative ketamine infusions and which ADEs most frequently led to discontinuation. Spine surgery was chosen because of its association with moderate to severe pain and a relatively high use of ketamine infusions in this population at our hospital.

    Hydrogen peroxide (H(2)O(2)) is a powerful oxidising agent. It gives rise to agents known to be effective bleaching agents. The mechanisms of bleaching involve the degradation of the extracellular matrix and oxidation of chromophores located within enamel and dentin. However, H(2)O(2) produces also local undesirable effects on tooth structures and oral mucosa. In clinical conditions, the daily low-level doses used to produce tooth whitening never generate general acute and sub-acute toxic effects. Genotoxicity and carcinogenicity only occur at concentrations that are never reached during dental treatments. Some transient adverse effects have been reported on the oral mucosa and the digestive tract if the product is swallowed. Local effects may occur on the oral mucosa and dental tissues during whitening, namely, pulp sensitivity, cervical resorption, release of selected components of dental restorative materials, and alteration of the enamel surface. Most of the local effects are dependent of the technique and concentration of the product so far used, but as the results of bleaching obtained are not stable, repeated treatments add to the adverse effects. The informed decision to administer or not and the control of bleaching effects should stand in the hand of dental surgeons and certainly not as it appears at present, as cosmetics sold without any restriction despite the potential health hazards of peroxides.

    Introduction The aim of the study was to determine the rate of exposure to domestic violence among female inpatients at any period of their lives; to investigate the effect of different forms of violence on the diagnoses and the course of the illness. Method The study was conducted on 102 female inpatients treated at Bakirkoy Research and Training Hospital for Psychiatry, Neurology and Neurosurgery. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) was administered and socio-demographic and clinical data was collected. A form designed for the assessment of violence was used to evaluate domestic violence. Results Ninety patients reported that they had been subjected to some kind of violence at some period of their lives. The parents or husbands were the most frequently reported persecutors. Seventy-three patients reported that they had been subjected to violence before the onset of their illness. Seventy-one had been subjected to physical, 79 to verbal, 42 to sexual, 52 to economic violence, and 49 to constraints on social relationship formation. Comorbid diagnosis of post traumatic stress disorder (PTSD) was related to all types of violence. The rate of suicide attempt was found to be significantly related to verbal-emotional violence. Only 12 patients had previously reported being subjected to domestic violence to their psychiatrist. Conclusion Domestic violence, an often overlooked phenomenon, is prevalent among women with psychiatric disorders. Subjection to domestic violence is found to be correlated with PTSD and suicidal attempt.

  3. Sedimentary selenium as a causal factor for adverse biological effects: Toxicity thresholds and stream modeling

    Selenium (Se) in the aquatic environment exhibits a strong association with particulate organic matter and as a result, measurements of waterborne concentration can be an unreliable predictor of bioaccumulation and adverse effects. Particulate-bound Se, typically measured as sedimentary Se, has been repeatedly implicated as a causal factor for Se bioaccumulation and subsequent potential for reproductive failures in fish and/or birds at sites receiving coal-fired power plant and refinery effluents as well as irrigation drainage. In fact, the premise that adverse biological effects are largely induced by sedimentary Se satisfies all of Hill`s criteria for a causal association. Despite these findings, most efforts to control Se continue to focus on waterborne concentrations because sedimentary toxicity thresholds are largely unknown. Sedimentary Se and associated biological effects data from studies of Se-bearing industrial effluent and irrigation drainage were compiled to initiate development of biological effects thresholds, The probability of adverse effects on fish or birds appears to be low up to a sedimentary Se concentration of about 2.8 {micro}g/g dry weight and high at 6.4 {micro}g/g dry weight (10th and 50th percentile of effects data, respectively). In addition, a preliminary regression model was derived for predicting dissolved to sedimentary Se transfer in streams as an interactive function of site-specific sedimentary organic carbon content (R{sup 2} = 0,870, p < 0.001) based on irrigation drainage studies in Colorado. This dissolved Se interaction with sedimentary organic carbon provides a possible explanation for the variable biological response to waterborne Se-organic-rich sites are predisposed to greater Se bioaccumulation and subsequent biological effects than organic-poor sites.

    Amphetamine stimulants have been used medically since early in the twentieth century, but they have a high abuse potential and can be neurotoxic. Although they have long been used effectively to treat attention deficit hyperactivity disorder (ADHD) in children and adolescents, amphetamines are now being prescribed increasingly as maintenance therapy for ADHD and narcolepsy in adults, considerably extending the period of potential exposure. Effects of prolonged stimulant treatment have not been fully explored, and understanding such effects is a research priority. Because the pharmacokinetics of amphetamines differ between children and adults, reevaluation of the potential for adverse effects of chronic treatment of adults is essential. Despite information on the effects of stimulants in laboratory animals, profound species differences in susceptibility to stimulant-induced neurotoxicity underscore the need for systematic studies of prolonged human exposure. Early amphetamine treatment has been linked to slowing in height and weight growth in some children. Because the number of prescriptions for amphetamines has increased several fold over the past decade, an amphetamine-containing formulation is the most commonly prescribed stimulant in North America, and it is noteworthy that amphetamines are also the most abused prescription medications. Although early treatment does not increase risk for substance abuse, few studies have tracked the compliance and usage profiles of individuals who began amphetamine treatment as adults. Overall, there is concern about risk for slowed growth in young patients who are dosed continuously, and for substance abuse in patients first medicated in late adolescence or adulthood. Although most adult patients also use amphetamines effectively and safely, occasional case reports indicate that prescription use can produce marked psychological adverse events, including stimulant-induced psychosis. Assessments of central toxicity and adverse

    Several meta-analyses have demonstrated the effectiveness of treatment utilizing cognitive behavioral therapy (CBT) combined with medication. There is, however, a paucity of research comparing the effectiveness of this combined treatment with psychiatric patients from different ethnic backgrounds. This study is the first of its kind to compare the effectiveness of CBT combined with medication for Asian American and White patients' psychiatric symptom severity levels of depression, anxiety, psychological well-being, and quality of life. The study examined the effects of CBT combined with medication for 43 Asian American and 43 White Non-Hispanic patients at an acute psychiatric partial hospital. A 2×2 between-within repeated measures analysis of variance was used. Results indicated significant improvement after treatment in all symptom categories assessed for the Asian American and White patients. The findings displayed trends over the course of treatment toward a greater decrease in anxiety symptoms among Asian patients but a larger increase in functioning level among White patients. In conclusion, the findings from this study provide preliminary cross-cultural support for CBT combined with medication as a treatment in partial hospital settings and suggest that the effectiveness of such treatments is similar across cultural groups.

    We surveyed undergraduate students' perceptions of psychiatric nurses' effectiveness and analyzed other sources of data. Students reported that psychiatric nurses' strengths include helping in situations that involve psychiatric symptoms, mental health evaluation, and drug abuse. Psychiatric nurses also were said to be effective when helping an individual with psychiatric symptoms, such as delusions and hallucinations. Friends or associates, common knowledge, school and education, and movies are some sources by which students learn about psychiatric nurses. Sources that provided less influential information include insurance carriers, newspapers, and personal experience.

    Childhood adversity plays an important role for development of major depressive disorder (MDD). There are differences in subcortical brain structures between patients with MDD and healthy controls, but the specific impact of childhood adversity on such structures in MDD remains unclear. Thus, aim of the present study was to investigate whether childhood adversity is associated with subcortical volumes and how it interacts with a diagnosis of MDD and sex. Within the ENIGMA-MDD network, nine university partner sites, which assessed childhood adversity and magnetic resonance imaging in patients with MDD and controls, took part in the current joint mega-analysis. In this largest effort world-wide to identify subcortical brain structure differences related to childhood adversity, 3036 participants were analyzed for subcortical brain volumes using FreeSurfer. A significant interaction was evident between childhood adversity, MDD diagnosis, sex, and region. Increased exposure to childhood adversity was associated with smaller caudate volumes in females independent of MDD. All subcategories of childhood adversity were negatively associated with caudate volumes in females - in particular emotional neglect and physical neglect (independently from age, ICV, imaging site and MDD diagnosis). There was no interaction effect between childhood adversity and MDD diagnosis on subcortical brain volumes. Childhood adversity is one of the contributors to brain structural abnormalities. It is associated with subcortical brain abnormalities that are relevant to psychiatric disorders such as depression.

    Diesel exhaust (DE) exposure induces adverse cardiopulmonary effects. Cerium oxide nanoparticles added to diesel fuel (DECe) increases fuel burning efficiency but leads to altered emission characteristics and potentially altered health effects. Here, we evaluated whether DECe results in greater adverse pulmonary effects compared with DE. Male Sprague Dawley rats were exposed to filtered air, DE, or DECe for 5 h/day for 2 days. N-acetyl glucosaminidase activity was increased in bronchial alveolar lavage fluid (BALF) of rats exposed to DECe but not DE. There were also marginal but insignificant increases in several other lung injury biomarkers in both exposure groups (DECe > DE for all). To further characterize DECe toxicity, rats in a second study were exposed to filtered air or DECe for 5 h/day for 2 days or 4 weeks. Tissue analysis indicated a concentration- and time-dependent accumulation of lung and liver cerium followed by a delayed clearance. The gas-phase and high concentration of DECe increased lung inflammation at the 2-day time point, indicating that gas-phase components, in addition to particles, contribute to pulmonary toxicity. This effect was reduced at 4 weeks except for a sustained increase in BALF γ-glutamyl transferase activity. Histopathology and transmission electron microscopy revealed increased alveolar septa thickness due to edema and increased numbers of pigmented macrophages after DECe exposure. Collectively, these findings indicate that DECe induces more adverse pulmonary effects on a mass basis than DE. In addition, lung accumulation of cerium, systemic translocation to the liver, and delayed clearance are added concerns to existing health effects of DECe.

    Diesel exhaust (DE) exposure induces adverse cardiopulmonary effects. Cerium oxide nanoparticles added to diesel fuel (DECe) increases fuel burning efficiency but leads to altered emission characteristics and potentially altered health effects. Here, we evaluated whether DECe results in greater adverse pulmonary effects compared with DE. Male Sprague Dawley rats were exposed to filtered air, DE, or DECe for 5 h/day for 2 days. N-acetyl glucosaminidase activity was increased in bronchial alveolar lavage fluid (BALF) of rats exposed to DECe but not DE. There were also marginal but insignificant increases in several other lung injury biomarkers in both exposure groups (DECe > DE for all). To further characterize DECe toxicity, rats in a second study were exposed to filtered air or DECe for 5 h/day for 2 days or 4 weeks. Tissue analysis indicated a concentration- and time-dependent accumulation of lung and liver cerium followed by a delayed clearance. The gas-phase and high concentration of DECe increased lung inflammation at the 2-day time point, indicating that gas-phase components, in addition to particles, contribute to pulmonary toxicity. This effect was reduced at 4 weeks except for a sustained increase in BALF γ-glutamyl transferase activity. Histopathology and transmission electron microscopy revealed increased alveolar septa thickness due to edema and increased numbers of pigmented macrophages after DECe exposure. Collectively, these findings indicate that DECe induces more adverse pulmonary effects on a mass basis than DE. In addition, lung accumulation of cerium, systemic translocation to the liver, and delayed clearance are added concerns to existing health effects of DECe. PMID:25239632

    Recommendations (best practices) are provided by the Society of Toxicologic Pathology's Adversity Working Group for making consistent interpretations of test article-related effects as "adverse" and assigning a "no observed adverse effect level" (NOAEL) in nonclinical toxicity studies. Adverse is a term indicating "harm" to the test animal, while nonadverse indicates lack of harm. Adverse findings in the study reports should be defined in relation to effects on the test species used and within the context of the given study. Test article-related effects should be described on their own merits, and decisions to consider them as adverse or nonadverse should be justified. Related effects may be discussed together; in particular, markers of toxicity that are not in and of themselves adverse ideally should be discussed in conjunction with the causal toxicity to determine adversity. Adverse findings should be identified in subreports (clinical data, pathology data, etc.) if sufficient information is available, and/or in the final study report as individual or grouped findings, but study NOAELs should be established at the level of the overall study report. Interpretations such as "not biologically relevant" or "not toxicologically important" should be avoided unless defined and supported by scientific rationale. Decisions defining adverse findings and the NOAEL in final study reports should combine the expertise of all contributing scientific disciplines. Where possible, use of NOAELs in data tables should be linked to explanatory text that places them in context. Ideally, in nonclinical summary documents, NOAELs from multiple studies are considered together in defining the most important adverse responses in the most sensitive species. These responses are then considered along with an understanding of their likely mechanisms, as well as other information such as variability in species sensitivity, comparative pathology, reversibility and progression, kinetics, and

    Nanoscale engineering is one of the most dynamically growing areas at the interface between electronics, physics, biology, and medicine. As there are no safety regulations yet, concerns about future health problems are rising. We investigated the effects of citrate/gold nanoparticles at different concentrations and exposure times on human dermal fibroblasts. We found that, as a result of intracellular nanoparticle presence, actin stress fibers disappeared, thereby inducing major adverse effects on cell viability. Thus, properties such as cell spreading and adhesion, cell growth, and protein synthesis to form the extracellular matrix were altered dramatically. These results suggest that the internal cell activities have been damaged.

    Electroconvulsive therapy (ECT) is frequently used in the treatment of major depression and other psychiatric disorders; its mechanism of action is not established, but previous evidence suggests that it is associated with postictal metabolic suppression. The authors have used measurements of rCBF as an index of cortical metabolic activity to study the acute effects of ECT. Measurements of rCBF were made in 32 cortical regions in 10 patients (pts) following one minute breathing of Xe-133 (5mCi/L); the measurements were performed 30min before and 50min after ECT. Bilateral ECT was administered to six pts (five diagnosed as major depressives and one schizophrenic) and unilateral ECT to four (all diagnosed as unipolar or bipolar affective disorder). The total rCBF material consists of 52 measurements in these pts, made before and after 16 bilateral and 10 unilateral treatments. ECT was found to cause significant reduction of rCBF. Mean hemispheric flows (using the Initial Slope Index to measure grey-matter flow) were reduced by about 5% in both hemispheres following bilateral treatment. Unilateral treatment caused a 9% reduction of flow in the treated hemisphere, but only 2% contralaterally. Regional patterns of flow decreases also differed between the two treatment modes: bilateral frontal reductions were found after bilateral treatment, whereas unilateral ECT caused a widespread flow reduction in the treated hemisphere, and almost no effect contralaterally. These results suggest that rCBF studies are useful for assessing ECT, and indicate that the acute cerebral effects of ECT vary with the mode of treatment.

    Recent rapid growth in the range of contraceptive products has given women more choice, but also adds complexity to the resultant decision of which product to choose. This paper uses a discrete choice experiment (DCE) to investigate the effect of adverse information and positive promotion on women's stated preferences for prescribed contraceptive products. In November 2007, 527 Australian women aged 18-49 years were recruited from an online panel. Each was randomly allocated to one of three information conditions. The control group only received basic information on contraceptive products. One treatment group also received adverse information on the risks of the combined oral pill. The other group received basic information and promotional material on the vaginal ring, newly introduced into Australia and on the transdermal patch, which is unavailable in Australia. Respondents completed 32 choice sets with 3 product options where each option was described by a product label: either combined pill, minipill, injection, implant, hormonal IUD, hormonal vaginal ring, hormonal transdermal patch or copper IUD; and by the attributes: effect on acne, effect on weight, frequency of administration, contraceptive effectiveness, doctor's recommendation, effect on periods and cost. Women's choices were analysed using a generalized multinomial logit model (G-MNL) and model estimates were used to predict product shares for each information condition. The predictions indicated that adverse information did not affect women's preferences for products relative to only receiving basic information. The promotional material increased women's preferences for the transdermal patch. Women in all groups had a low preference for the vaginal ring which was not improved by promotion. The findings highlight the need for researchers to pay attention to setting the context when conducting DCEs as this can significantly affect results.

    Finasteride and dutasteride, both 5-alpha reductase inhibitors, are considered first-line treatment for androgenetic hair loss in men and used increasingly in women. In each case, patients are expected to take the medications indefinitely despite the lack of research regarding long-term adverse effects. Concerns regarding the adverse effects of these medications has led the United States National Institutes of Health to add a link for post-finasteride syndrome to its Genetic and Rare Disease Information Center. Herein, the authors report the results of a literature search reviewing adverse events of 5-alpha reductase inhibitors as they relate to prostate cancer, psychological effects, sexual health, and use in women. Several large studies found no increase in incidence of prostate cancer, a possible increase of high-grade cancer when detected, and no change in survival rate with 5-alpha reductase inhibitor use. Currently, there is no direct link between 5-alpha reductase inhibitor use and depression; however, several small studies have led to depression being listed as a side effect on the medication packaging. Sexual effects including erectile dysfunction and decreased libido and ejaculate were reported in as many as 3.4 to 15.8 percent of men. To date, there are very few studies evaluating 5-alpha reductase inhibitor use in women. Risks include birth defects in male fetuses if used in pregnancy, decreased libido, headache, gastrointestinal discomfort, and isolated reports of changes in menstruation, acne, and dizziness. Overall, 5-alpha reductase inhibitors were well-tolerated in both men and women, but not without risk, highlighting the importance of patient education prior to treatment. PMID:27672412

    Ipilimumab, an antibody that blocks cytotoxic T lymphocyte-associated antigen-4 (CTLA-4; CD152), was approved by the Food and Drug Administration (FDA) in 2011 for the treatment of unresectable stage III or IV malignant melanoma. Although the addition of this particular immunotherapy has broadened treatment options, immune-related adverse events (irAEs) are associated with ipilimumab therapy, including dermatologic effects, colitis and diarrhea, endocrine effects, hepatotoxicity, ocular effects, renal effects, neurologic effects, and others. In this article, a critical evaluation of the underlying mechanisms of irAEs associated with anti-CTLA-4 therapy is presented. Additionally, potentially beneficial effects of combinational therapies to alleviate ipilimumab-induced irAEs in malignant melanoma are discussed. Future research is warranted to elucidate the efficacy of such combination therapies as well as specific biomarkers that would help to predict a clinical response to ipilimumab in patients with malignant melanoma.

    Finasteride is currently used extensively for male androgenic alopecia and benign prostatic hyperplasia; however, some adverse effects are severe and even persistent after treatment cessation, the so-called 'post-finasteride syndrome'. The following most severe adverse effects-sexual dysfunction and depression-often occur together and may potentiate one other, a fact that could explain (at least in part) the magnitude and persistence of finasteride adverse effects. This paper presents the pharmacological action of finasteride and the corresponding adverse effects, the biological base explaining the occurrence, persistence and distribution of these adverse effects, and a possible therapeutic solution for post-finasteride syndrome. The distribution of finasteride adverse effects is presented within a comprehensive and modern neuro-endocrine perspective related to structural and informational dichotomies of the brain. Understanding the variation of finasteride side effects among different populations would be necessary not only to delineate the safety profile of finasteride for different subgroups of men (a subject may or may not be affected by a certain anti-hormonal compound dependent on the individual neuro-endocrine profile), but also as a possible premise for a therapeutic approach of finasteride adverse effects. Such therapeutic approach should include administration of exogenous hormones, which are deficient in men with post-finasteride syndrome, namely dihydrotestosterone (in right-handed men) or progesterone/dihydroprogesterone (in left-handed subjects).

    Cancer is the most dreadful disease affecting mankind. The available treatments such as chemotherapy and radiotherapy have cytotoxic effects, which are hazardous to the normal cells of the patient, causing many unnecessary effects. This further leads to complications of the therapy, impaired health, and deterioration of quality of life, resulting in mandatory stoppage of the treatment. In the present study, the efficacy of an Ayurvedic formulation, Rasayana Avaleha, has been evaluated as an adjuvant medication to modern radiotherapy and chemotherapy. A total of 36 cancer patients were registered in this trial and were divided into two groups, group A and group B. In group A, the patients were treated with radiotherapy and chemotherapy along with adjuvant Rasayana Avaleha (RT + CT + RA), while in group B only radiotherapy and chemotherapy (RT + CT) were given, as the control group. After assessing the results, it was observed that Rasayana Avaleha gave better results in controlling the adverse effect of chemotherapy and radiotherapy in comparison with the control group. Therefore, Rasayana Avaleha has proved to be an effective adjuvant therapy in protecting patients from the adverse effects of chemotherapy and radiotherapy. PMID:22048532

  19. Apoptosis May Explain the Pharmacological Mode of Action and Adverse Effects of Isotretinoin, Including Teratogenicity.

    2017-02-08

    Isotretinoin (13-cis retinoic acid) is the most effective sebum-suppressive drug for the treatment of severe acne. Its effect depends on sebocyte apoptosis, which results from isotretinoin-induced expression of the apoptotic protein tumour necrosis factor-related apoptosis-inducing ligand, insulin-like growth factor-binding protein-3 and neutrophil gelatinase-associated lipocalin. This review proposes that the pharmacological mode of action of isotretinoin in the treatment of severe acne, acute promyelocytic leukaemia, and neuroblastoma results from apoptosis. Furthermore, apoptosis may be the underlying and unifying mechanism of the adverse effects of isotretinoin on neural crest cells (teratogenicity), hippocampal neurones (depression), epidermal keratinocytes and mucosa cells (mucocutaneous side-effects), hair follicle cells (telogen effluvium), intestinal epithelial cells (inflammatory bowel disease), skeletal muscle cells (myalgia and release of creatine kinase), and hepatocytes (release of transaminases and very low-density lipoproteins). Genetic variants of components of the apoptotic signalling cascade, such as RARA polymorphisms, might explain variations in the magnitude of isotretinoin-induced apoptotic signalling and apparently identify subgroups of patients who experience either stronger adverse effects with isotretinoin therapy or resistance to treatment.

    The Proceedings of a Canadian Working Group Consensus Conference, first published in 2011, provided a summary of statin-associated adverse effects and intolerance and management suggestions. In this update, new clinical studies identified since then that provide further insight into effects on muscle, cognition, cataracts, diabetes, kidney disease, and cancer are discussed. Of these, the arenas of greatest controversy pertain to purported effects on cognition and the emergence of diabetes during long-term therapy. Regarding cognition, the available evidence is not strongly supportive of a major adverse effect of statins. In contrast, the linkage between statin therapy and incident diabetes is more firm. However, this risk is more strongly associated with traditional risk factors for new-onset diabetes than with statin itself and any possible negative effect of new-onset diabetes during statin treatment is far outweighed by the cardiovascular risk reduction benefits. Additional studies are also discussed, which support the principle that systematic statin rechallenge, and lower or intermittent statin dosing strategies are the main methods for dealing with suspected statin intolerance at this time.

    The U.S. Food and Drug Administration (FDA) periodically publishes Drug Safety Communications and Drug Alerts notifying health care practitioners and the general public of important information regarding drug therapies following FDA approval. These alerts can result in both positive and negative effects on patient care. Most clinical trials are not designed to detect long-term safety end points, and postmarketing surveillance along with patient reported events are often instrumental in signaling the potential harmful effect of a drug. Recently, many cardiovascular (CV) safety announcements have been released for FDA-approved drugs. Because a premature warning could discourage a much needed treatment or prompt a sudden discontinuation, it is essential to evaluate the evidence supporting these FDA alerts to provide effective patient care and to avoid unwarranted changes in therapy. Conversely, paying attention to these warnings in cases involving high-risk patients can prevent adverse effects and litigation. This article reviews the evidence behind recent FDA alerts for drugs with adverse CV effects and discusses the clinical practice implications.

    Melamine is a heterocyclic, aromatic amine and nitrogen-enriched environmental toxicant, found in not only adulterated foodstuffs but also industrial household tableware and paints. Previous studies demonstrated adverse effects of high-dose melamine on human infants and pregnant animals, but effects of low-dose melamine on pregnancy have not been reported. In this study, reproductive effects of low-dose melamine were investigated in pregnant rats. Melamine in the range of 12.5-50 mg/kg was administered to pregnant rats at different gestational stages. Maternal weight gain was not significantly affected, and other maternal morbidity was not observed. Low-dose melamine exposure during pregnancy increased fetal size but reduced somite number in gastrulation (GD8.5-GD10.5) and organogenesis (GD10.5-GD16.5) periods, and increased incidence of stillbirth in whole gestational period (GD0.5 to delivery). Embryotoxicity of melamine was further confirmed by whole embryo culture in vitro that melamine retarded embryonic growth, impaired development of brain and heart, and induced open neural tube and atrioventricular defects with increased apoptosis. In conclusion, adverse reproductive effects of low-dose melamine during pregnancy were identified in the developing rat embryos and the perinatal effects of melamine were gestational and developmental stage dependent. Detailed hazard and risk assessment of melamine in reproduction system are warrant. © 2015 Wiley Periodicals, Inc. Environ Toxicol 32: 131-138, 2017.

  3. Time-Dependent Effects in Algae for Chemicals with Different Adverse Outcome Pathways: A Novel Approach.

    PubMed

    Vogs, Carolina; Altenburger, Rolf

    2016-07-19

    Chemicals affect unicellular algae as a result of toxicokinetic and toxicodynamic processes. The internal concentration of chemicals in algae cells typically reaches equilibrium within minutes, while damage cumulatively increases over hours. The time gap between the steady state of internal exposure and damage development is thus suspected to span up to hours, mainly due to toxicodynamic processes. The quantification of rate-limited toxicodynamic processes, aggregated as a progressive effect from an initiating molecular event through biological key events toward the adverse outcome on algae growth inhibition, might discriminate between different adverse outcome pathways (AOPs). To support our hypothesis, we selected six chemicals according to different physicochemical properties and three distinctly dissimilar AOPs. The time courses of internal concentrations were linked to the observed affected Scenedesmus vacuolatus growth using toxicokinetic-toxicodynamic modeling. Effects on cell growth were explained by effect progression and not by the time to reach internal equilibrium concentration. Effect progression rates ranged over 6 orders of magnitude for all chemicals but varied by less than 1 order of magnitude within similar AOP (photosystem II inhibitors > reactive chemicals > lipid biosynthesis inhibitors), meaning that inhibitors of photosystem II advance an effect toward algae growth fastest compared to reactive chemicals and inhibitors of lipid biosynthesis.

    Most laxatives, if used intermittently in the absence of contraindications, are relatively safe. Bulking agents may diminish absorption of some minerals and drugs, but this is not usually clinically significant. Ispaghula can cause serious allergic reactions. The chronic ingestion of stimulant laxatives has been blamed for the development of the 'cathartic colon', but there are no definitive studies which have demonstrated this. Dantron (danthron) preparations should only be used in older patients and the terminally ill because of the risk of hepatotoxicity with this drug. Oral oxyphenisatine should no longer be used. Senna would appear to be the stimulant laxative of choice during pregnancy and lactation. Bisacodyl is the polyphenolic derivative of choice. Lactulose, sorbitol and lactilol rarely cause significant adverse effects. Magnesium salt laxatives and phosphate enemas can cause serious metabolic disturbances in babies and young children. Liquid paraffin is contraindicated if there is any risk of aspiration. Interference with the absorption of fat soluble vitamins would not appear to be clinically significant. Docusate sodium may potentiate the hepatotoxicity of other drugs, but reports of this are rare. The role of cisapride in constipation has not been established. Antidiarrhoeal drugs are second line drugs whose use is aimed at minimising inconvenience and discomfort. No antidiarrhoeals can be recommended for children under 4 years of age. Loperamide is the drug of choice in older children and adults. The atropine component of diphenoxylate/atropine combinations can cause significant adverse effects. Bismuth salicylate is an inconvenient treatment for travellers' diarrhoea as large frequent doses of the liquid formulation are needed. Some bismuth can be absorbed and there is the potential to cause encephalopathy. Octreotide, methysergide and cholestyramine have a role for specific causes of diarrhoea only. Octreotide is effective in high output states

    Obesity is an established risk factor for postmenopausal breast cancer (BCa), insulin resistance, and vitamin D deficiency, and all contribute to increased synthesis of mammary estrogens, the drivers of estrogen receptor-positive (ER+) BCa growth. As both dietary vitamin D and calcitriol treatments inhibit breast estrogen synthesis and signaling, we hypothesized that vitamin D would be especially beneficial in mitigating the adverse effects of obesity on ER+BCa. To assess whether obesity exerted adverse effects on BCa growth and whether vitamin D compounds could reduce these unfavorable effects, we employed a diet-induced obesity (DIO) model in ovariectomized C57BL/6 mice. Breast tumor cells originally from syngeneic Mmtv-Wnt1 transgenic mice were then implanted into the mammary fat pads of lean and obese mice. DIO accelerated the initiation and progression of the mammary tumors. Treatments with either calcitriol or dietary vitamin D reduced the adverse effects of obesity causing a delay in tumor appearance and inhibiting continued tumor growth. Beneficial actions of treatments with vitamin D or calcitriol on BCa and surrounding adipose tissue included repressed Esr1, aromatase, and Cox2 expression; decreased tumor-derived estrogen and PGE2; reduced expression of leptin receptors; and increased adiponectin receptors. We demonstrate that vitamin D treatments decreased insulin resistance, reduced leptin, and increased adiponectin signaling and also regulated the LKB1/AMPK pathway contributing to an overall decrease in local estrogen synthesis in the obese mice. We conclude that calcitriol and dietary vitamin D, acting by multiple interrelated pathways, mitigate obesity-enhanced BCa growth in a postmenopausal setting.

    There are connection between use of cannabis and many psychiatric disturbances in adolescents, especially "cannabis psychosis", depression, panic attacks and suicide. Negative effects could occur either as a result of a specific pharmacological effect of cannabis, or as the result of stressful experiences during the intoxication of cannabis in young people. Potentially is very dangerous high frequency suicidal ideation among cannabis users.

    Psychiatric rehabilitation has become accepted by the mental health field as a legitimate field of study and practice. Over the last several decades various psychiatric rehabilitation programme models and procedures have been developed, evaluated and disseminated. At the same time the process of psychiatric rehabilitation has been specified and its underlying values and practitioner technology articulated. This review describes the psychiatric rehabilitation process and in so doing differentiates psychosocial interventions that can be classified as psychiatric rehabilitation interventions from other psychosocial interventions. Furthermore, the major psychiatric rehabilitation interventions are examined within a framework of the psychiatric rehabilitation process with a review of their evidence. The review concludes that psychiatric rehabilitation interventions are currently a mixture of evidence-based practices, promising practices and emerging methods that can be effectively tied together using the psychiatric rehabilitation process framework of helping individuals with serious mental illnesses choose, get and keep valued roles, and together with complementary treatment orientated psychosocial interventions, provide a broad strategy for facilitating recovery.

  10. Putative Kappa Opioid Heteromers As Targets for Developing Analgesics Free of Adverse Effects

    PubMed Central

    2015-01-01

    It is now generally recognized that upon activation by an agonist, β-arrestin associates with G protein-coupled receptors and acts as a scaffold in creating a diverse signaling network that could lead to adverse effects. As an approach to reducing side effects associated with κ opioid agonists, a series of β-naltrexamides 3–10 was synthesized in an effort to selectively target putative κ opioid heteromers without recruiting β-arrestin upon activation. The most potent derivative 3 (INTA) strongly activated KOR-DOR and KOR-MOR heteromers in HEK293 cells. In vivo studies revealed 3 to produce potent antinociception, which, when taken together with antagonism data, was consistent with the activation of both heteromers. 3 was devoid of tolerance, dependence, and showed no aversive effect in the conditioned place preference assay. As immunofluorescence studies indicated no recruitment of β-arrestin2 to membranes in coexpressed KOR-DOR cells, this study suggests that targeting of specific putative heteromers has the potential to identify leads for analgesics devoid of adverse effects.

Here we examine the impact of intravenously injected drug-free nanocarriers on the cardiovasculature at both the systemic and organ levels. We combine in vivo and in vitro methods to enable monitoring of hemodynamic parameters in conscious rats, assessments of the function of the vessels after sub-chronic systemic exposure to nanocarriers and evaluation of the direct effect of nanocarriers on vascular tone. We demonstrate that nanocarriers can decrease blood pressure and increase heart rate in vivo via various mechanisms. Depending on the type, nanocarriers induce the dilation of the resistance arteries and/or change the responses induced by vasoconstrictor or vasodilator drugs. No direct correlation between physicochemical properties and cardiovascular effects of nanoparticles was observed. The proposed combination of methods empowers the studies of cardiovascular adverse effects of the nanocarriers.

    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.

    It is now generally recognized that upon activation by an agonist, β-arrestin associates with G protein-coupled receptors and acts as a scaffold in creating a diverse signaling network that could lead to adverse effects. As an approach to reducing side effects associated with κ opioid agonists, a series of β-naltrexamides 3-10 was synthesized in an effort to selectively target putative κ opioid heteromers without recruiting β-arrestin upon activation. The most potent derivative 3 (INTA) strongly activated KOR-DOR and KOR-MOR heteromers in HEK293 cells. In vivo studies revealed 3 to produce potent antinociception, which, when taken together with antagonism data, was consistent with the activation of both heteromers. 3 was devoid of tolerance, dependence, and showed no aversive effect in the conditioned place preference assay. As immunofluorescence studies indicated no recruitment of β-arrestin2 to membranes in coexpressed KOR-DOR cells, this study suggests that targeting of specific putative heteromers has the potential to identify leads for analgesics devoid of adverse effects.

  14. Nutraceuticals in psychiatric practice.

    2012-08-01

    Nutraceuticals can be defined as food components or active principles present in aliments which have positive effects for health and quality of life, including preventing or treating disorders. Herbal and "natural" food supplements are increasingly used to treat different psychiatric disorders, often as "self-prescribed" therapies. With factors such as chronic illness, poor health, emotional distress, and quality of life influencing the desire for complementary medicine, patients with comorbid medical and psychiatric problems seem likely to turn to this approach. We reviewed the most commonly used herbal and dietary supplements for which a certain efficacy on psychiatric symptoms or disorders has been claimed, checking current Pubmed-indexed literature (the most important being St. John's wort, Omega-3 fatty acids, valerian, Kava, Ginkgo, folate, B vitamins, S-Adenosylmethionine, inositol, alfa-lactoalbumin and passionflower). There is evidence of efficacy for some of these herbs an supplements, proved also by Cochrane's meta-analysis. However many different areas (including efficacy, tolerability, optimal dosing, adequate shelf life, drug and non-pharmacological interactions) need to be thoroughly studied; moreover political decisions need to be scientifically guided in order to best serve psychiatric patients' interests and to prevent using of expensive and sometimes un-useful therapies. This implies that a scientific strategy is needed to rule out any third-part economical interest which could in any way influence therapeutic choices. The article presents some promising patents on nutraceuticals in psychiatric practice.

  15. Risk, mercury levels, and birds: relating adverse laboratory effects to field biomonitoring.

    There is an abundance of field data on levels of mercury in a variety of organisms and there are a number of studies that demonstrate the adverse effects of mercury on laboratory animals, but few studies examine the relationship between the two. Thus it is often difficult to determine the ecological relevance of mercury concentrations found in nature, or to predict the ecosystem consequences of current levels. In this paper we review the levels in tissues that are associated with adverse effects in birds from laboratory studies and compare these with levels found in wild bird populations in the New York Bight to provide a basis for interpreting values in avian populations. We use feathers from fledgling birds which would have been fed on locally obtained food to eliminate the problem of where toxic burdens were acquired by more mobile adult birds. Laboratory studies indicate that in some species mercury levels of 1.5 ppm in eggs and/or 5 to 40 ppm in the feathers of birds are associated with adverse effects, including impaired reproduction. We report egg levels in birds that range as high as 3.8 ppm and feather levels that range as high as 10.3 ppm, although means are much lower. The levels in eggs of some wild birds in the New York Bight are within the range known to lower hatchability, embryo and chick survival, and chick weight, all variables that reduce reproductive success. Species with high egg levels include Forster's tern (Sterna forsteri) and black skimmer (Rynchops niger). Levels in feathers of some young wild birds from the New York Bight are within the range associated with reduced hatchability of eggs, behavioral abnormalities of adults, and infertility. Species with dangerously elevated mercury levels in feathers include great egret (Ardea [=Egretta] alba), snowy egret [Egretta thula), and black skimmers.

  16. Epigenetics and transcriptomics to detect adverse drug effects in model systems of human development.

    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.

    2016-01-01

    Background: Our aim was to investigate the effects of clinical application of perioperative predictive nursing on reducing psychiatric complications in Intensive Care Unit (ICU) patients after neurosurgery. Methods: A total of 129 patients who underwent neurosurgery and received intensive care were enrolled in our study from February 2013 to February 2014. These patients were divided into two groups: the experimental group (n=68) receiving predictive nursing before and after operation, and the control group (n=61) with general nursing. Clinical data including length of ICU stay, duration of the patients’ psychiatric symptoms, form and incidence of adverse events, and patient satisfaction ratings were recorded, and their differences between the two groups were analyzed. Results: The duration of psychiatric symptoms and the length of ICU stay for patients in the experimental group were significantly shorter than those in the control group (P<0.05). The incidence of adverse events and psychiatric symptoms, such as sensory and intuition disturbance, thought disturbance, emotional disorder, and consciousness disorder, in the experimental group was significantly lower than that in the control group (P<0.05). Patient satisfaction ratings were significantly higher in the experimental group than those in the control group (P<0.05). Conclusion: Application of predictive nursing on ICU patients who undergo neurosurgery could effectively reduce the incidence of psychiatric symptoms as well as other adverse events. Our study provided clinical evidences to encourage predictive nursing in routine settings for patients in critical conditions. PMID:27252916

    Children (n = 126) ages 9 to 17 years with chronic tic or Tourette disorder were randomly assigned to receive either behavior therapy or a control treatment over 10 weeks. This study examined acute effects of behavior therapy on secondary psychiatric symptoms and psychosocial functioning and long-term effects on these measures for behavior therapy responders only. Baseline and end point assessments conducted by a masked independent evaluator assessed several secondary psychiatric symptoms and measures of psychosocial functioning. Responders to behavior therapy at the end of the acute phase were reassessed at 3-month and 6-month follow-up. Children in the behavior therapy and control conditions did not differentially improve on secondary psychiatric or psychosocial outcome measures at the end of the acute phase. At 6-month posttreatment, positive response to behavior therapy was associated with decreased anxiety, disruptive behavior, and family strain and improved social functioning. Behavior therapy is a tic-specific treatment for children with tic disorders. PMID:21555779

    Clinical trials of intranasal administration of oxytocin for treating psychiatric problems have yielded mixed results. To conduct a quantitative review of placebo-controlled clinical trials of intranasally-administered oxytocin (OT) for psychiatric symptoms, manual and electronic searches using PubMed and PsycINFO were conducted. Of 1,828 entries, 16 placebo-controlled studies totaling 330 participants were included in the analysis. The overall placebo-controlled effect size was moderately strong (Hedges’ g = 0.67) and robust as suggested by the fail-safe N and funnel plot analysis. OT reduced symptoms of depression, anxiety, autism/repetitive behaviors, psychotic symptoms, and general psychopathology. In the combined sample, symptom reduction was moderated by frequency of administration. Publication year and diagnostic category did not moderate the effect of OT on the clinical outcome measures. We conclude that intranasal administration of OT is a potentially useful intervention for reducing psychiatric symptoms. However, more studies are needed to determine the best treatment target and to identify the mechanism of treatment change. PMID:26094200

Informational and psychological nature of dissemination of these inventions is analyzed. On the basis of recent literature data conclusion was made about the absence of real toxicity (including neurotoxicity), carcinogenicity, allergenicity and autopathogenicity of phenol, folmaldehyde, aluminium hydroxide, Twin 80, squalen (MF59) and ethylmercury in concentrations found in vaccines of national immunization schedule.

    Objective: To evaluate the possible interaction between religious beliefs and psychiatric disorders among Black Americans. Methods: In this study, we used data of 5181 adult Black Americans who had participated in National Survey of American Life (NSAL) from February 2001 to June 2003. Variables such as socio-demographics, religious beliefs, and psychiatric disorders were entered in a Cox regression to determine the possible interaction between psychiatric disorders (0, 1, ≥2) and the subjective religiosity on age of onset of suicidal thought among the participants. Main outcome was age of the first serious suicidal ideation. Results: A dose-dependent effect of number of psychiatric disorders on suicidal ideation was observed. Psychiatric disorders had a higher impact on age of suicidal ideation among those with low self-reported religiosity. Conclusion: Religious beliefs may buffer the effect of psychiatric disorders on suicidal thought. Blacks who are less religious and suffer psychiatric disorders are at the highest risk for early suicidal ideation. PMID:22708032

    We report the results of administration of the Portuguese-Brazilian translation of the Liverpool Adverse Events Profile (LAEP) to 100 patients (mean age=34.5, SD=12.12; 56 females), 61 with symptomatic partial epilepsy (SPE) and 39 with idiopathic generalized epilepsy (IGE) (ILAE, 1989) who were on a stable antiepileptic drug (AED) regimen and being treated in a Brazilian tertiary epilepsy center. Carbamazepine was the most commonly used AED (43.0%), followed by valproic acid (32.0%). Two or more AEDs were used by 69.0% of patients. The mean LAEP score (19 questions) was 37.6 (SD=13.35). The most common adverse effects were sleepiness (35.0%), memory problems (35.0%), and difficulty in concentrating (25.0%). Higher LAEP scores were associated with polytherapy with three or more AEDs (P=0.005), female gender (P<0.001), older age (P<0.001), and uncontrolled seizures (P=0.045). The intraclass coefficient (test-retest reliability) for LAEP overall score was 0.848 (95% CI=0.782-0.895), with a range from 0.370 (unsteadiness) to 0.750 (memory problems). Cronbach's α coefficient (internal consistency) was 0.903. The LAEP was highly correlated with Quality of Life in Epilepsy-31 inventory (r=-0.804, P>0.001) and Hospital Anxiety and Depression Scale (Depression: r=0.637, P<0.001; Anxiety: r=0.621, P<0.001) dimensions. LAEP overall scores were similar in people with SPE and IGE and were not helpful in differentiating adverse effects in these two groups. Clinical variables that influenced global LAEP were seizure frequency (P=0.050) and generalized tonic-clonic seizures in the last month (P=0.031) in the IGE group, and polytherapy with three or more AEDs (P=0.003 and P=0.003) in both IGE and SPE groups.

    The purpose of this study was to compare group-based psychoeducational music therapy to psychoeducation in measures of satisfaction with life, knowledge of illness, treatment perceptions, and response frequency and type in acute psychiatric inpatients during a randomized and controlled clinical trial. Participants (N=105) took part in a scripted single session controlled by a treatment manual and facilitated by a Board-Certified Music Therapist. No significant differences were found between groups in measures of helpfulness, enjoyment, satisfaction with life, or psychoeducational knowledge. However, although not significant, the music therapy group tended to have slightly higher mean scores in all aforementioned variables, suggesting music therapy can be as effective as psychoeducation in these measures. There were no significant differences between groups for the number of therapist questions and validations as measured by a trained behavioral observer, although during the music therapy condition the therapist was able to ask a mean of almost 11 additional questions than during the psychoeducational control condition. Although not significant, there were almost 20 more participant mean verbalizations per session during the music therapy conditions. Additionally, many of these verbalizations were categorized as self and cognitive insight statements, indicating participants in the music therapy condition were talking more about themselves and their unique situations. Congruent with this finding, during the music therapy condition, the ratios of participant self statements to therapist questions and participant cognitive insights to therapist questions were higher than in the control condition. There was a significant correlation between participant total verbal participation and perception of helpfulness, enjoyment, and comfort for the control condition. This correlation was not significant for the experimental condition, indicating that the music therapy group did

  7. How antibiotics can make us sick: the less obvious adverse effects of antimicrobial chemotherapy.

    PubMed

    Dancer, Stephanie J

    2004-10-01

    Antimicrobial agents are associated with side-effects, which are usually tolerated because the benefits of treatment outweigh the toxic effects. Clinicians know about these side-effects but are less likely to understand additional adverse events, such as the overgrowth of resistant microorganisms. Overgrowth can itself precipitate a secondary infection, which can be more difficult to treat. Resistant organisms then spread to other patients and the environment, and contribute to increasing antimicrobial resistance worldwide. Organisms exposed to antibiotics undergo molecular changes that might enhance virulence. Enhanced pathogenicity would affect patients, particularly if the organism is also multiply resistant. Clinicians have a responsibility to select the correct antibiotic as soon as they have diagnosed infection, but an absence of microbiological understanding and ignorance of the potential environmental effects have contributed to inappropriate prescribing. The less obvious results of antimicrobial consumption probably go unrecognised in routine clinical care.

    Short interfering RNA (siRNA) is a potent activator of the mammalian innate immune system. When considering possible clinical applications of siRNA for humans, the adverse immunostimulatory effects must also be taken into account. Here, we show that atelocollagen-mediated systemic delivery of siRNA without chemical modifications did not cause any immunostimulation in both animals and human peripheral blood mononuclear cells (PBMCs), even if the siRNA harbored an interferon (IFN)-inducible sequence. In contrast, systemic delivery of immunostimulatory RNA (isRNA)-mediated by a cationic lipid (such as Invivofectamine) induced potent type-I IFNs and inflammatory cytokines. Regarding the mechanism by which the isRNA/atelocollagen complex avoided adverse effects on immunostimulation, we revealed that this complex was not incorporated into PBMCs. On the other hand, Invivofectamine delivered isRNA into PBMCs. The use of either atelocollagen or Invivofectamine as a vehicle elicited significant and undistinguishable therapeutic effects in a contact hypersensitivity (CHS) inflammatory model mouse, when we intravenously injected the siRNA targeting monocyte chemoattractant protein-1 as the complex. For the goal of realizing siRNA-based medicines for humans, atelocollagen is an excellent and promising delivery vehicle, and it has the useful advantage of evading detection by the “radar” of innate immunity.

    2016-10-01

    We propose a computationally efficient probabilistic modeling methodology to estimate the adverse effects on humans of exposure to contaminated groundwater. Our work is aligned with the standard suggested by the regulatory agencies and allows to propagate uncertainty from hydrogeological, toxicological and behavioral parameters to the final health risk endpoint. The problem under consideration consists of a contaminated aquifer supplying water to a population. Contamination stems from a continuous source that feeds a steady plume which constitutes the hazard source. This scenario is particularly suited for NAPL pollutants. The erratic displacement of the contaminant plume in groundwater, due to the spatial variability of hydraulic conductivity, is characterized within the Lagrangian stochastic framework which enables the complete probabilistic characterization of the contaminant concentration at an environmentally sensitive location. Following the probabilistic characterization of flow and transport, we quantify the adverse health effects on humans. The dose response assessment involves the estimation of the uncertain effects of the exposure to a given contaminant while accounting for the exposed individual's metabolism. The model integrates groundwater transport, exposure and human metabolism in a comprehensive probabilistic framework which allows the assessment of the risk probability through a novel simple analytical solution. Aside from its computational efficiency, the analytical features of the framework allows the assessment of uncertainty arising from the hydrogeological parameters.

    Cyproheptadine prevention of the neuropsychiatric adverse effects of an antiretroviral regimen including efavirenz has been evaluated in a randomized clinical trial. Twenty-five patients (16 males and 9 females with mean±SD ages of 36±9 years) in a cyproheptadine group, and 26 patients (17 males and 9 females with mean±SD ages of 34±7 years) in a control group completed the trial. Sexual contact and injection drug use were the main routs of HIV infection in both groups. The patients' neuropsychiatric adverse effects were evaluated based on the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Positive and Negative Syndrome Scale, Beck Depression Scale, Pittsburgh Sleep Quality Inventory, Positive and Negative Suicide Ideation, and Somatization Subscale of Symptom Checklist 90 at baseline and 4 weeks after treatment. Cyproheptadine significantly decreased the scores of Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Positive and Negative Syndrome Scale, Beck Depression Scale, Pittsburgh Sleep Quality Inventory, Positive and Negative Suicide Ideation of the patients after 4 weeks in comparison with control group. All of the scores increased in control group following antiretroviral therapy. Although short duration of the patients' follow-up was a major limitation of the study, the results of the study showed that cyprohepradine is effective in prevention of depression, anxiety, hallucination, aggressive behaviors, emotional withdrawal, poor rapport, poor impulse control, active social avoidance, suicidal ideation, and improved sleep quality of HIV-positive patients after initiation of antiretroviral therapy including efavirenz.

    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

    2001-06-01

    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

    Background There is substantial evidence that mortality increases in low temperatures. Less is known about the role of prolonged cold periods denoted as cold spells. Objective We conducted the first systematic review and meta-analysis to summarize the evidence on the adverse health effects of cold spells in varying climates. Data sources and extraction Four databases (Ovid Medline, PubMed, Scopus, Web of Science) were searched for all years and languages available. “Cold spell” was defined as an event below a temperature threshold lasting for a minimum duration of 2 days. Of 1,527 identified articles, 26 satisfied our eligibility criteria for the systematic review, and 9 were eligible for meta-analyses. The articles were grouped by the three main study questions into Overall-effect Group, Added-effect Group, and Temperature-change-effect Group. Data synthesis Based on random-effects models in the meta-analyses, cold spells were associated with increased mortality from all or all nonaccidental causes (summary rate ratio = 1.10; 95% CI: 1.04, 1.17 based on 9 estimates from five studies), cardiovascular diseases (1.11; 95% CI: 1.03, 1.19; 12 estimates from eight studies), and respiratory diseases (1.21; 95% CI: 0.97, 1.51; 8 estimates from four studies). Estimated associations were stronger for people ≥ 65 years of age (1.06; 95% CI: 1.00, 1.12) than for people 0–64 years of age (1.01; 95% CI: 1.00, 1.03). Study-specific effect estimates from a limited number of studies suggested an increased morbidity related to cold spells, but it was not possible to quantitatively summarize the evidence. Conclusions Cold spells are associated with increased mortality rates in populations around the world. The body of evidence suggests that cold spells also have other adverse health effects. There was substantial heterogeneity among the studies, which should be taken into account in the interpretation of the results. Citation Ryti NR, Guo Y, Jaakkola JJ. 2016. Global

  14. Manganese inhibits NMDA receptor channel function: implications to psychiatric and cognitive effects.

    Humans exposed to excess levels of manganese (Mn(2+)) express psychiatric problems and deficits in attention and learning and memory. However, there is a paucity of knowledge on molecular mechanisms by which Mn(2+) produces such effects. We now report that Mn(2+) is a potent inhibitor of [(3)H]-MK-801 binding to the NMDA receptor channel in rat neuronal membrane preparations. The inhibition of [(3)H]-MK-801 to the NMDA receptor channel by Mn(2+) was activity-dependent since Mn(2+) was a more potent inhibitor in the presence of the NMDA receptor co-agonists glutamate and glycine (K(i)=35.9+/-3.1 microM) than in their absence (K(i)=157.1+/-6.5 microM). We also show that Mn(2+) is a NMDA receptor channel blocker since its inhibition of [(3)H]-MK-801 binding to the NMDA receptor channel is competitive in nature. That is, Mn(2+) significantly increased the affinity constant (K(d)) with no significant effect on the maximal number of [(3)H]-MK-801 binding sites (B(max)). Under stimulating conditions, Mn(2+) was equipotent in inhibiting [(3)H]-MK-801 binding to NMDA receptors expressed in neuronal membrane preparations from different brain regions. However, under basal, non-stimulated conditions, Mn(2+) was more potent in inhibiting NMDA receptors in the cerebellum than other brain regions. We have previously shown that chronic Mn(2+) exposure in non-human primates increases Cu(2+), but not zinc or iron concentrations in the basal ganglia [Guilarte TR, Chen M-K, McGlothan JL, Verina T, Wong DF, Zhou Y, Alexander M, Rohde CA, Syversen T, Decamp E, Koser AJ, Fritz S, Gonczi H, Anderson DW, Schneider JS. Nigrostriatal dopamine system dysfunction and subtle motor deficits in manganese-exposed non-human primates. Exp Neurol 2006a;202:381-90]. Therefore, we also tested the inhibitory effects of Cu(2+) on [(3)H]-MK-801 binding to the NMDA receptor channel. The data shows that Cu(2+) in the presence of glutamate and glycine is a more potent inhibitor of the NMDA receptor than Mn(2

    Aim Exposure to road traffic and air pollution may be a trigger of acute myocardial infarction, but the individual pollutants responsible for this effect have not been established. We assess the role of combustion-derived-nanoparticles in mediating the adverse cardiovascular effects of air pollution. Methods and results To determine the in vivo effects of inhalation of diesel exhaust components, 16 healthy volunteers were exposed to (i) dilute diesel exhaust, (ii) pure carbon nanoparticulate, (iii) filtered diesel exhaust, or (iv) filtered air, in a randomized double blind cross-over study. Following each exposure, forearm blood flow was measured during intra-brachial bradykinin, acetylcholine, sodium nitroprusside, and verapamil infusions. Compared with filtered air, inhalation of diesel exhaust increased systolic blood pressure (145 ± 4 vs. 133 ± 3 mmHg, P< 0.05) and attenuated vasodilatation to bradykinin (P= 0.005), acetylcholine (P= 0.008), and sodium nitroprusside (P< 0.001). Exposure to pure carbon nanoparticulate or filtered exhaust had no effect on endothelium-dependent or -independent vasodilatation. To determine the direct vascular effects of nanoparticulate, isolated rat aortic rings (n= 6–9 per group) were assessed in vitro by wire myography and exposed to diesel exhaust particulate, pure carbon nanoparticulate and vehicle. Compared with vehicle, diesel exhaust particulate (but not pure carbon nanoparticulate) attenuated both acetylcholine (P< 0.001) and sodium-nitroprusside (P= 0.019)-induced vasorelaxation. These effects were partially attributable to both soluble and insoluble components of the particulate. Conclusion Combustion-derived nanoparticulate appears to predominately mediate the adverse vascular effects of diesel exhaust inhalation. This provides a rationale for testing environmental health interventions targeted at reducing traffic-derived particulate emissions. PMID:21753226

    Limited evidence shows that time-limited residential treatment (RT) is beneficial for homeless people with serious mental illness. The Department of Veterans Affairs has established 11 specialty programs for homeless female veterans. We present data comparing 1-year clinical outcomes in a group of veterans who did and did not receive at least 30 days of RT. Clients of the Homeless Women Veterans Programs were invited to participate in a follow-up study. They were interviewed every 3 months for 1 year. Those who received at least 30 days of RT in the 3 months after program entry (RT group) were compared with other program participants (no or <30 days RT [NRT] group) on measures of community functioning, psychiatric symptoms, and drug and alcohol use during the follow-up. The RT group had better outcomes on employment, social support, housing status, and psychiatric symptoms. They also had significantly increased use of drugs and alcohol compared with the NRT group. Data suggest that RT may have a beneficial effect on mental health outcomes in homeless women. This study, in conjunction with others, suggests that provision of stable housing may be an important element of recovery for homeless women with psychiatric problems, excluding substance use.

    Irritable bowel syndrome (IBS) is a gastrointestinal disorder linked to disturbances in the gut-brain axis. Visceral hypersensitivity and pain are hallmarks of IBS and linked to the physiological and psychological burden and to the nonadaptive coping with stress. Cognitive-behavioral therapy (CBT) for IBS has proven effective in reducing gastrointestinal and psychiatric symptoms in IBS by means of coping with stress. The present pilot study evaluated for the first time whether CBT for IBS affected visceral sensitivity and pain. Individual CBT was performed for 12 weeks in 18 subjects with IBS and evaluated in terms of visceral sensitivity and pain during rectal distensions using the barostat method and self-rated visceral sensitivity and gastrointestinal and psychiatric symptoms. Visceral discomfort, urge, and pain induced by the barostat were not affected by CBT but were stable across the study. However, the level of self-rated visceral sensitivity and gastrointestinal and psychiatric symptoms decreased after the intervention. Central working mechanisms and increased ability to cope with IBS-symptoms are suggested to play a key role in the alleviation of IBS symptoms produced by CBT. PMID:28210270

    Valproic acid (VPA) is a drug used for the treatment of epilepsy, bipolar psychiatric disorders, and migraine. Previous studies have reported an increased generation of reactive oxygen species and oxidative stress in the toxic mechanism of VPA. Edaravone, a free radical scavenger for clinical use, can quench free radical reaction by trapping a variety of free radical species. In this study, effect of edaravone on some small intestine biochemical parameters in VPA-induced toxicity was investigated. Thirty seven Sprague Dawley female rats were randomly divided into four groups. The groups include control group, edaravone (30 mg(-1) kg(-1) day(-1)) given group, VPA (0.5 g(-1) kg(-1) day(-1)) given group, VPA + edaravone (in same dose) given group. Edaravone and VPA were given intraperitoneally for 7 days. Biochemical parameters such as malondialdehyde, as an index of lipid peroxidation(LPO), sialic acid (SA), glutathione levels and glutathione peroxidase, glutathione-S-transferase, superoxide dismutase, catalase, myeloperoxidase, alkaline phosphatase (ALP), and tissue factor (TF) activities were determined in small intestine samples by colorimetric methods. Decreased small intestine antioxidant enzyme activities, increased LPO and SA levels, and increased activities of ALP and TF were detected in the VPA group. Based on our results edaravone may be suggested to reverse the oxidative stress and inflammation due to VPA-induced small intestine toxicity.

  19. Adverse Effects Associated with Protein Intake above the Recommended Dietary Allowance for Adults.

    Background. While high-protein consumption-above the current recommended dietary allowance for adults (RDA: 0.8 g protein/kg body weight/day)-is increasing in popularity, there is a lack of data on its potential adverse effects. Objective. To determine the potential disease risks due to high protein/high meat intake obtained from diet and/or nutritional supplements in humans. Design. Review. Subjects. Healthy adult male and female subjects. Method. In order to identify relevant studies, the electronic databases, Medline and Google Scholar, were searched using the terms:"high protein diet," "protein overconsumption," "protein overuse," and "high meat diet." Papers not in English were excluded. Further studies were identified by citations in retrieved papers. Results. 32 studies (21 experimental human studies and 11 reviews) were identified. The adverse effects associated with long-term high protein/high meat intake in humans were (a) disorders of bone and calcium homeostasis, (b) disorders of renal function, (c) increased cancer risk, (d) disorders of liver function, and (e) precipitated progression of coronary artery disease. Conclusions. The findings of the present study suggest that there is currently no reasonable scientific basis in the literature to recommend protein consumption above the current RDA (high protein diet) for healthy adults due to its potential disease risks. Further research needs to be carried out in this area, including large randomized controlled trials.

    Organophosphate (OP) compounds are the most widely used pesticides with more than 100 OP compounds in use around the world. The high-intensity use of OP pesticides contributes to morbidity and mortality in farmworkers and their families through acute or chronic pesticides-related illnesses. Many factors contributing to adverse health effects have been investigated by researchers to determine pathways of OP-pesticide exposure among farmers in developed and developing countries. Factors like wind/agricultural pesticide drift, mixing and spraying pesticides, use of personal protective equipment (PPE), knowledge, perceptions, washing hands, taking a shower, wearing contaminated clothes, eating, drinking, smoking, and hot weather are common in both groups of countries. Factors including low socioeconomic status areas, workplace conditions, duration of exposure, pesticide safety training, frequency of applying pesticides, spraying against the wind, and reuse of pesticide containers for storage are specific contributors in developing countries, whereas housing conditions, social contextual factors, and mechanical equipment were specific pathways in developed countries. This paper compares existing research in environmental and behavioural exposure modifying factors and biological monitoring between developing and developed countries. The main objective of this review is to explore the current depth of understanding of exposure pathways and factors increasing the risk of exposure potentially leading to adverse health effects specific to each group of countries.

    The purpose of the study was to investigate the noise pollution situation and the resulting adverse effect on residents' health in Luzhou, China, to provide data for noise pollution prevention policies and interventions. Four different functional areas (commercial, construction, residential, and transportation hub areas) were chosen to monitor noise level for 3 months. The survey was performed by questionnaire on the spot on randomly selected individuals; it collected data on the impact of noise on residents' health (quality of sleep, high blood pressure, subjective feeling of nervous system damage, and attention) as well as the knowledge of noise-induced health damage, the degree of adaptation to noise, and their solutions. The noise levels of residential, commercial, transportation, and construction areas exceeded the national standards (P < .001). Sleep quality, prevalence of hypertension, and attention in transportation hub areas were significantly different from those in the other 3 areas (P < .05); only 24.46% of people knew the health hazards associated with noise; 64.57% of residents have adapted to the current noise environment. Most of them have to close the doors and windows to reduce noise. The noise pollution situation in Luzhou, China, is serious, especially the traffic noise pollution. Residents pay less attention to it and adopt single measures to reduce the noise. We should work toward the prevention and control of traffic noise and improve the residents' awareness to reduce the adverse health effects of noise.

    Residential wood burning is a major source of poorly characterized, deleterious particulate matter, whose composition and toxicity may vary with wood type, burning condition and photochemical age. The causative link between ambient wood particle constituents and observed adverse health effects is currently lacking. Here we investigate the relationship between chemical properties of primary and atmospherically aged wood combustion particles and acute toxicity in human airway epithelial cells. Emissions from a log wood burner were diluted and injected into a smog chamber for photochemical aging. After concentration-enrichment and removal of oxidizing gases, directly emitted and atmospherically aged particles were deposited on cell cultures at the air-liquid interface for 2 hours in an aerosol deposition chamber mimicking physiological conditions in lungs. Cell models were fully differentiated normal and diseased (cystic fibrosis and asthma) human bronchial epithelia (HBE) and the bronchial epithelial cell line BEAS-2B. Cell responses were assessed at 24 hours after aerosol exposure. Atmospherically relevant doses of wood combustion particles significantly increased cell death in all but the asthma cell model. Expression of oxidative stress markers increased in HBE from all donors. Increased cell death and inflammatory responses could not be assigned to a single chemical fraction of the particles. Exposure to primary and aged wood combustion particles caused adverse effects to airway epithelia, apparently induced by several interacting components.

    This study elucidated differences in predisposition to the gastrointestinal adverse effects of ketoprofen between young and adult cats. Ketoprofen was administered subcutaneously (2.0 mg/kg, s.c.) once a day for 3 days. The animals were sacrificed 24 hr after final injection to allow examination of gastrointestinal mucosal lesions. Ketoprofen caused gastric lesions in adult cats (>6 months) but not in young cats (<3 months). Ketoprofen caused more severe small intestinal lesions in adult cats than in young cats. In the study of prevention of lipopolysaccharide (LPS)-induced hyperthermia using ketoprofen, young and adult cats of both sexes were administered LPS (0.3 μg/kg, intravenously), and body temperature was measured 24 hr later. Ketoprofen was administered subcutaneously 30 min before LPS injection. LPS-induced hyperthermia was almost completely inhibited by pretreatment with ketoprofen in both adult and young cats. In the pharmacokinetics of ketoprofen, plasma concentrations were analyzed by high-performance liquid chromatography. No significant differences were observed in plasma concentrations of two mirror-image R(-) and S(+) ketoprofen between young and adult cats from 0.5-4 hr after injection. As observed in a previous study using flunixin, the degree of gastrointestinal damage was unrelated to plasma concentrations of ketoprofen. The results of this study demonstrated that ketoprofen is safer for use in young cats than in adult cats from the viewpoint of gastrointestinal adverse effects.

    The discovery of the human papillomavirus (HPV) vaccine illustrates the power of in situ-based pathologic analysis in better understanding and curing diseases. The 2 available HPV vaccines have markedly reduced the incidence of cervical intraepithelial neoplasias, genital warts, and cervical cancer throughout the world. Concerns about HPV vaccine safety have led some physicians, health care officials, and parents to refuse providing the recommended vaccination to the target population. The aims of the study were to discuss the discovery of HPV vaccine and review scientific data related to measurable outcomes from the use of HPV vaccines. The strong type-specific immunity against HPV in humans has been known for more than 25 years. Multiple studies confirm the positive risk benefit of HPV vaccination with minimal documented adverse effects. The most common adverse effect, injection site pain, occurred in about 10% of girls and was less than the rate reported for other vaccines. Use of HPV vaccine should be expanded into more diverse populations, mainly in low-resource settings.

    Registered nurses (RNs) play a pivotal role in treating pain and preventing and recognizing the adverse effects (AEs) of analgesics in patients with dementia. The purpose of this study was to determine RNs' knowledge of potentially clinically relevant AEs of analgesics. A descriptive, cross-sectional study design was used. In all, 267 RNs treating orthopedic patients, including patients with dementia, in 7 university hospitals and 10 central hospitals in Finland, completed a questionnaire. Analgesics were defined according to the Anatomic Therapeutic Classification as strong opioids, weak opioids, nonsteroidal anti-inflammatory analgesics (NSAIDs), and paracetamol. Definitions of AEs were based on the literature. Logistic regression analysis was applied to analyze which variables predicted nurses' knowledge. The RNs had a clear understanding of the AEs of paracetamol and strong opioids. However, the AEs of NSAIDs, especially renal and cardiovascular AEs, were less well known. The median percentage of correct answers was 87% when asked about strong opioids, 73% for weak opioids, and 60% for NSAIDs. Younger RNs had better knowledge of opioid-related AEs (odds ratio [OR] per 1-year increase, 0.97; 95% confidence interval [CI], 0.94-1.00) and weak opioids (OR, 0.96; 95% CI, 0.93-0.99). This study provides evidence of a deficiency in RNs' knowledge, especially regarding the adverse renal and cardiovascular effects of NSAIDs. Such lack of knowledge indicates that hospitals may need to update the knowledge of older RNs, especially those who treat vulnerable patients with dementia.

    With the onset of the AIDS epidemic, major changes occurred in blood banking and transfusion medicine. These changes occurred mainly in donor selection and screening tests for infectious diseases, blood centers modified their organizational philosophy regarding quality. Transfusion of blood products are procedures that allow us to correct the haematology deficiencies for which was indicated. But today, despite the strict controls that precede transfusion,recipients may have undesirable effects, which are known as adverse effects or adverse reactions to transfusion. Antibodies and antigens of the HLA system plays a role in a series of events related to transfusion, such as immunological platelet refractoriness, febrile non-haemolytic transfusion reactions, transfusion related acute lung injury (TRALI) and transfusion-associated graft-versus-host disease. The determination of anti-HLA antibodies is evidence that in most developed countries is used on a daily basis in the regular assessment of patients multitransfused or waiting lists for organs from deceased donors. The biomodulators are able to modify biological responses which act in sequence to lead to the differentiation of T lymphocytes. These agents may subcategorizes those which facilitate a normal immune response, those stimulates the immune response, those are capable of inducing immunosuppression not cytotoxic, and those enhancing the ability of the host to tolerate damage by cytotoxic treatment (transfusion or transplant).

    A retrospective cohort study was conducted among an international group of 46 law enforcement chemists and 13 Washington State clandestine drug laboratory investigation team members with more than 2,800 combined investigations. Each participant completed a questionnaire concerning previous drug laboratory investigations and adverse health effects during response activities. Methamphetamine laboratories accounted for 81-97% of all responses. Total illness incident rates varied between 0.75-3.4% of responses. Most exposures were through inhalation, and many occurred in the years prior to use of personal protective equipment. Symptoms were primarily those of headache and respiratory, mucous membrane, and skin irritation. Most illness episodes occurred during the processing phase of laboratory responses, and none occurred during the entry phase. A majority of illness episodes occurred in laboratories with leak/spills, fire/explosion, or uncontrolled reactions. Responding to an active laboratory was associated with a 7 to 15-fold risk of becoming ill as compared with setup, in-transit, or former (equipment removed) laboratory responses. No other laboratories characteristics were consistently associated with a significantly elevated relative risk of adverse health effects.

    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.

    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.

    Background Antenatal magnesium sulphate, widely used in obstetrics to improve maternal and infant outcomes, may be associated with adverse effects for the mother sufficient for treatment cessation. This systematic review aimed to quantify maternal adverse effects attributed to treatment, assess how adverse effects vary according to different regimens, and explore women’s experiences with this treatment. Methods Bibliographic databases were searched from their inceptions to July 2012 for studies of any design that reported on maternal adverse effects associated with antenatal magnesium sulphate given to improve maternal or infant outcomes. Primary outcomes were life-threatening adverse effects of treatment (death, cardiac arrest, respiratory arrest). For randomised controlled trials, data were meta-analysed, and risk ratios (RR) pooled using fixed-effects or random-effects models. For non-randomised studies, data were tabulated by design, and presented as RR, odds ratios or percentages, and summarised narratively. Results A total of 143 publications were included (21 randomised trials, 15 non-randomised comparative studies, 32 case series and 75 reports of individual cases), of mixed methodological quality. Compared with placebo or no treatment, magnesium sulphate was not associated with an increased risk of maternal death, cardiac arrest or respiratory arrest. Magnesium sulphate significantly increased the risk of 'any adverse effects’ overall (RR 4.62, 95% CI 2.42-8.83; 4 trials, 13,322 women), and treatment cessation due to adverse effects (RR 2.77; 95% CI 2.32-3.30; 5 trials, 13,666 women). Few subgroup differences were observed (between indications for use and treatment regimens). In one trial, a lower dose regimen (2 g/3 hours) compared with a higher dose regimen (5 g/4 hours) significantly reduced treatment cessation (RR 0.05; 95% CI 0.01-0.39, 126 women). Adverse effect estimates from studies of other designs largely supported data from randomised

    Objective Toward explicating relations between economic adversity and children’s sleep, we examined associations between multiple indicators of socioeconomic status (SES)/adversity and children’s objectively and subjectively derived sleep parameters; ethnicity was examined as potential moderator. Methods Participants were 276 third- and fourth-grade children and their families (133 girls; M age = 9.44 years; SD = .71): 66% European American (EA) and 34% African American (AA). Four SES indicators were used: income-to-needs ratio, perceived economic well-being, maternal education, and community poverty. Children wore actigraphs for 7 nights and completed a self-report measure to assess sleep problems. Results Objectively and subjectively assessed sleep parameters were related to different SES indicators, and overall worse sleep was evident for children from lower SES homes. Specifically, children from homes with lower income-to-needs ratios had higher levels of reported sleep/wake problems. Parental perceived economic well-being was associated with shorter sleep minutes and greater variability in sleep onset for children. Lower mother’s education was associated with lower sleep efficiency. Children who attended Title 1 schools had shorter sleep minutes. Ethnicity was a significant moderator of effects in the link between some SES indicators and children’s sleep. AA children’s sleep was more negatively affected by income-to-needs ratio and mother’s education than was the sleep of EA children. Conclusions The results advocate for the importance of specifying particular SES and sleep variables used because they may affect the ability to detect associations between sleep and economic adversity.

    Objective We examined the cost-effectiveness of smoking cessation treatment for psychiatric inpatients. Method Smokers, regardless of intention to quit, were recruited during psychiatric hospitalization and randomized to receive stage-based smoking cessation services or usual aftercare. Smoking cessation services, quality of life, and biochemically-verified abstinence from cigarettes were assessed during 18-months of follow-up. Trial findings were combined with literature on changes in smoking status and the age and gender adjusted effect of smoking on health care cost, mortality, and quality of life in a Markov model of cost-effectiveness during a lifetime horizon. Results Among 223 smokers randomized between 2006 and 2008, the mean cost of smoking cessation services was $189 in the experimental treatment group and $37 in the usual care condition (p < 0.001). At the end of follow-up, 18.75% of the experimental group was abstinent from cigarettes, compared to 6.80% abstinence in the usual care group (p <0.05). The model projected that the intervention added $43 in lifetime cost and generated 0.101 additional Quality Adjusted Life Years (QALYs), an incremental cost-effectiveness ratio of $428 per QALY. Probabilistic sensitivity analysis found the experimental intervention was cost-effective against the acceptance criteria of $50,000/QALY in 99.0% of the replicates. Conclusions A cessation intervention for smokers identified in psychiatric hospitalization did not result in higher mental health care costs in the short-run and was highly cost-effective over the long-term. The stage-based intervention was a feasible and cost-effective way of addressing the high smoking prevalence in persons with serious mental illness. PMID:26528651

    2017-03-17

    Health interventions commonly have adverse effects. Addressing these could significantly improve health outcomes. This paper addresses an adverse effect common in the promotion of health behaviours: exacerbation of health inequalities between low- and high-socioeconomic groups. Health behaviours - particularly, physical activity - are positioned within the context of social inequality and the inequitable spatial distribution of resources. Area-based health policy that targets deprived areas is assessed for its capacity to promote health behaviours without exacerbating inequality. Data are derived from a 16-month ethnography in a deprived English neighbourhood that was the target of area-based intervention that prioritised the promotion of physical activity. Findings provide evidence of adverse intervention effects that further disadvantaged the low-socioeconomic population. Analysis demonstrates how this was ultimately the outcome of localised policy drifting away from initial commitments to equitable service access. These findings increase understanding of the processes through which adverse intervention effects arise and how they can be mitigated.

    Radiation therapy is a common treatment regimen for cancer patients. However, its adverse effects on the neighboring bone could lead to fractures with a great impact on quality of life. The underlying mechanism is still elusive and there is no preventive or curative solution for this bone loss. Parathyroid hormone (PTH) is a current therapy for osteoporosis that has potent anabolic effects on bone. In this study, we found that focal radiation from frequent scans of the right tibiae in 1-month-old rats by micro-computed tomography severely decreased trabecular bone mass and deteriorated bone structure. Interestingly, PTH daily injections remarkably improved trabecular bone in the radiated tibiae with increases in trabecular number, thickness, connectivity, structure model index and stiffness, and a decrease in trabecular separation. Histomorphometric analysis revealed that radiation mainly decreased the number of osteoblasts and impaired their mineralization activity but had little effects on osteoclasts. PTH reversed these adverse effects and greatly increased bone formation to a similar level in both radiated and non-radiated bones. Furthermore, PTH protects bone marrow mesenchymal stem cells from radiation-induced damage, including a decrease in number and an increase in adipogenic differentiation. While radiation generated the same amount of free radicals in the bone marrow of vehicle-treated and PTH-treated animals, the percentage of apoptotic bone marrow cells was significantly attenuated in the PTH group. Taken together, our data demonstrate a radioprotective effect of PTH on bone structure and bone marrow and shed new light on a possible clinical application of anabolic treatment in radiotherapy.

    Sexual dysfunctions (SD) are adverse effects of common drug therapies that have rarely been considered in investigations so far. Possibly it is barely known that many widespread and frequently prescribed medications and drug therapies can have significant impact on vascular and nerval processes as well as on endocrinologic and psychoneuroendocrinologic systems and therefore can influence sexual functions. Impotence and disorders of the erectile function can mainly be caused by antidopaminergic mechanisms, whereas ejaculatory disorders and anorgasmia often can be explained by antiserotoninergic effects. Anticholinergic and adrenoloytic agents can also cause a particular impairment of erectile functions. The following considerations will show that the detection and treatment of SD (also in women!) should be given much more attention since drug-induced SDs occur predominantly in indications where a SD itself can be a symptom of the disease.

    Both Te inclusions and point defects can trap the charge carriers generated by ionizing particles in CdZnTe (CZT) detectors. The amount of charge trapped by point defects is proportional to the carriers’ drift time and can be corrected electronically. In the case of Te inclusions, the charge loss depends upon their random locations with respect to the electron cloud. Consequently, inclusions introduce fluctuations in the charge signals, which cannot be easily corrected. In this paper, we describe direct measurements of the cumulative effect of Te inclusions and its influence on the response of CZT detectors of different thicknesses and different sizes and concentrations of Te inclusions. We also discuss a means of partially correcting their adverse effects.

    Exposure to air pollution has long been known to trigger cardiovascular events, primarily through activation of local and systemic inflammatory pathways that affect the vasculature. Detrimental effects of air pollution exposure on heart failure and cardiac remodeling have also been described in human populations. Recent studies in both human subjects and animal models have provided insights into the basic physiological, cellular and molecular mechanisms that play a role in adverse cardiac remodeling. This review will give a brief overview of the relationship between air pollution and cardiovascular disease, describe the clinical effects of air pollution exposure on cardiac remodeling, describe the basic mechanisms that affect remodeling as described in human and animal systems and will discuss future areas of investigation.

    There are five approved, partially effective, parenteral disease-modifying therapies for multiple sclerosis (MS), including three interferon-beta preparations, glatiramer acetate and the antineoplastic agent mitoxantrone. A sixth drug, natalizumab, was withdrawn from the market in 2005 but could return with increased safety measures. Careful surveillance for, and management of, the minor and serious adverse effects associated with these therapies in routine practice provides the best opportunity for maintaining compliance and achieving maximal therapeutic efficacy. This review outlines the strategies for the prevention, identification and management of the complications associated with administration and ongoing use of current MS therapies. These skills will become increasingly important to those caring for MS patients as contemporary treatment regimens become increasingly complex.

  20. Oral Bisphosphonate Related Osteonecrosis of the Jaw: A Challenging Adverse Effect

    2013-01-01

    Oral bisphosphonates are the most commonly prescribed antiresorptive drugs for the treatment of osteoporosis. However, there are several adverse effects associated with oral bisphosphonates including the bisphosphonate related osteonecrosis of the jaw (BRONJ). With a better understanding of this side effect, reported incidences for BRONJ in oral bisphosphonate users have increased in time. The pathogenesis of BRONJ has not been well determined. Several risk factors such as dentoalveolar surgery, therapy duration, and concomitant steroid usage have been linked to BRONJ. Conservative and surgical methods can be preferred in the treatment. Preventative measures are of great importance for the patients at high risk. In this paper, osteonecrosis of the jaw secondary to oral bisphosphonates was reviewed in order to increase awareness as well as to renew the current knowledge. PMID:23762600

    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.

    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.

    Objective The aim of this study was to design and validate a questionnaire to measure perceived symptoms associated with antihypertensive drugs (PERSYVE). Methods The PERSYVE development and validation included four stages: 1) item development (bibliographic review and questionnaire elaboration); 2) face and content validation; 3) field testing (pre-test); and 4) test-retest validation, assessment of internal consistency (Cronbach’s alpha) and reproducibility over time (intraclass correlation coefficient and Cohen’s kappa coefficient). Results PERSYVE is divided into six sections according to results obtained from the literature review: (1) drug adherence, (2) perceived symptoms and how they affect quality of life (five-point Likert scale), (3) communication with health professionals, (4) perception of symptoms as adverse reactions, (5) influence on therapy compliance, and (6) adoption of non-pharmacological methods for blood pressure control. Content and face validation of the questionnaire led to some vocabulary changes and the introduction of section 2.1. Field-testing (n=26) revealed high comprehensibility of the questions. The Cronbach's alpha, calculated for section 2 (five-point Likert scale) was 0.850. PERSYVE was reproducible (n=167): kappa values presented fair to substantial reproducibility and, in section 2, ICC values resulted in good to excellent reproducibility. Conclusion Results showed that PERSYVE is a well-structured, objective, patient-friendly, valid and reliable questionnaire. PERSYVE can be a very useful instrument in hypertensive patients’ monitoring and in the screening of adverse effects. PMID:25035716

    A mobile phone intervention was developed and tested with 30 psychiatric outpatients with mental illness, who had high ideation for suicide. The intervention involved promoting help-seeking behaviors by sending text messages, including information about social welfare services and reminders about medical appointments, for 6 months. After the intervention period, the number of participants who used social services significantly increased, and more than 80% of participants reported that the text messaging service was helpful and useful. Compared to baseline, participants' self-harming behaviors decreased and the attending psychiatrists rated their suicide ideation as weaker. This is the first intervention study to promote psychiatric patients' help-seeking using text messaging, and although it was not a randomized controlled trial, this intervention has practical value and may lead to the prevention of suicide.

    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.

    The activation of the canonical Wnt/β-catenin signaling pathway in both mesenchymal stem cells and osteoblasts has been demonstrated to increase bone mass, showing promise for the treatment of low bone volume conditions such as osteoporosis. However, the possible side effects of manipulating this pathway have not been fully addressed. Previously, we reported that the constitutive activation of ß-catenin in osteoblasts impaired vertebral linear growth. In the present study, β-catenin was constitutively activated in osteocytes by crossing Catnb+/lox(exon 3) mice with dentin matrix protein 1(DMP1)-Cre transgenic mice, and the effects of this activation on bone mass, bone growth and bone strength were then observed. DMP1-Cre was found to be predominantly expressed in osteocytes, with weak expression in a small portion of osteoblasts and growth plate chondrocytes. After the activation, the cancellous bone mass was dramatically increased, almost filling the entire bone marrow cavity in long bones. However, bone strength decreased significantly. Thinner and more porous cortical bone along with impaired mineralization were responsible for the decrease in bone strength. Furthermore, the mice showed shorter stature with impaired linear growth of the long bones. Moreover, the concentration of serum phosphate decreased significantly after the activation of ß-catenin, and a high inorganic phosphate (Pi) diet could partially rescue the phenotype of decreased mineralization level and impaired linear growth. Taken together, the constitutive activation of β-catenin in osteocytes may increase cancellous bone mass; however, the activation also had adverse effects on bone strength and bone growth. These adverse effects should be addressed before the adoption of any therapeutic clinical application involving adjustment of the Wnt/β-catenin signaling pathway.

  7. Suicides on the Austrian railway network: hotspot analysis and effect of proximity to psychiatric institutions

    Railway suicide is a significant public health problem. In addition to the loss of lives, these suicides occur in public space, causing traumatization among train drivers and passengers, and significant public transport delays. Prevention efforts depend upon accurate knowledge of clustering phenomena across the railway network, and spatial risk factors. Factors such as proximity to psychiatric institutions have been discussed to impact on railway suicides, but analytic evaluations are scarce and limited. We identify 15 hotspots on the Austrian railway system while taking case location uncertainties into account. These hotspots represent 0.9% of the total track length (5916 km/3676 miles) that account for up to 17% of all railway suicides (N=1130). We model suicide locations on the network using a smoothed inhomogeneous Poisson process and validate it using randomization tests. We find that the density of psychiatric beds is a significant predictor of railway suicide. Further predictors are population density, multitrack structure and—less consistently—spatial socio-economic factors including total suicide rates. We evaluate the model for the identified hotspots and show that the actual influence of these variables differs across individual hotspots. This analysis provides important information for suicide prevention research and practice. We recommend structural separation of railway tracks from nearby psychiatric institutions to prevent railway suicide.

  8. Adverse drug effects attributed to phenylpropanolamine: a review of 142 case reports.

    Phenylpropanolamine (PPA) is contained in about 106 products, over half of which are available over-the-counter (OTC). Most are cough/cold remedies; nine are OTC diet aids. More than nine million Americans were using OTC diet aids in 1981, making PPA the fifth most used drug in the United States, responsible for over $200 million in revenues. The safety of PPA remains controversial. Although most controlled studies indicate minimal pressor effects with recommended doses, adverse drug reactions (ADRs) continue to be documented. Since 1965, 142 ADRs have been reported in 85 studies, 69% of these in North America. Many such cases may go unrecognized. About two thirds of all ADRs occurred in females and in patients under 30. Of ADRs attributed to legitimately sold PPA products, 85% occurred after consumption of OTC products versus only 15% after prescription drugs. The PPA product often contained combination ingredients, or PPA was consumed along with additional drugs. An overdose of PPA was taken in about a third of the cases. After ingestion of non-overdose amounts, 82% of the ADRs were severe. The most frequent side effects involved symptoms compatible with acute hypertension, with severe headache the most common complaint. Twenty-four intracranial hemorrhages, eight seizures, and eight deaths (most due to stroke) were associated with PPA ingestion. We have summarized these data in an effort to alert clinicians to the prevalence of usage of PPA products and the potential for adverse effects. In patients who present with elevated blood pressure or signs of acute hypertension, especially hypertensive encephalopathy of undetermined origin, we recommend inquiry about recent ingestion of PPA-containing diet aids and cough/cold products and suggest having such patients remain upright rather than supine.

    In this study, we elucidated the difference in nonsteroidal anti-inflammatory drug sensitivities between young and adult cats on therapeutic and adverse effects. In the prevention of lipopolysaccharide (LPS)-induced hyperthermia using flunixin-meglumine, young (<3 months old) and adult (>12 months old) cats of both sexes were given LPS (0.3 µg/kg, i.v.), and body temperature was measured 24 hr later. Flunixin (1 mg/kg, s.c.) was administered 30 min before the LPS injection. LPS-induced hyperthermia was almost completely inhibited by pre-treatment with flunixin in both adult and young cats. In addition, flunixin showed almost the same antipyretic effects in both young and adult cats. The animals were administered flunixin (1 mg/kg, s.c.) once a day for 3 days, and sacrificed 24 hr later to examine the gastrointestinal mucosal lesions. In adult cats, flunixin caused many severe lesions in the small intestine. In contrast, very few gastrointestinal lesions were produced by flunixin in young cats. In the pharmacokinetics of flunixin, plasma concentrations of flunixin were analysed using a high performance liquid chromatography. There were no significant differences in plasma concentration of flunixin between young and adult cats from 0.5 to 4 hr after the injection. These results demonstrated that NSAIDs could be used more safely in young than in adult cats from the points of gastrointestinal adverse effects. Furthermore, this difference in gastrointestinal lesions between adult and young cats was not related with the plasma concentration of flunixin.

    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.

    The results of an in-flight simulation program undertaken to study the problems of landing a representative STOL transport in the presence of adverse ground effects are presented. Landings were performed with variations in ground effect magnitude, ground effect lag, and thrust response. Other variations covered the effects of augmented lift response, SAS-failures, turbulence, segmented approach, and flare warning. The basic STOL airplane required coordinated use of both stick and throttle for consistently acceptable landings, and the presence of adverse ground effects made the task significantly more difficult. Ground effect lag and good engine response gave noticeable improvement, as did augmented lift response.

    Both historical clinical and recent preclinical data suggest that the M1 muscarinic acetylcholine receptor is an exciting target for the treatment of Alzheimer's disease and the cognitive and negative symptom clusters in schizophrenia; however, early drug discovery efforts targeting the orthosteric binding site have failed to afford selective M1 activation. Efforts then shifted to focus on selective activation of M1 via either allosteric agonists or positive allosteric modulators (PAMs). While M1 PAMs have robust efficacy in rodent models, some chemotypes can induce cholinergic adverse effects (AEs) that could limit their clinical utility. Here, we report studies aimed at understanding the subtle structural and pharmacological nuances that differentiate efficacy from adverse effect liability within an indole-based series of M1 ago-PAMs. Our data demonstrate that closely related M1 PAMs can display striking differences in their in vivo activities, especially their propensities to induce adverse effects. We report the discovery of a novel PAM in this series that is devoid of observable adverse effect liability. Interestingly, the molecular pharmacology profile of this novel PAM is similar to that of a representative M1 PAM that induces severe AEs. For instance, both compounds are potent ago-PAMs that demonstrate significant interaction with the orthosteric site (either bitopic or negative cooperativity). However, there are subtle differences in efficacies of the compounds at potentiating M1 responses, agonist potencies, and abilities to induce receptor internalization. While these differences may contribute to the differential in vivo profiles of these compounds, the in vitro differences are relatively subtle and highlight the complexities of allosteric modulators and the need to focus on in vivo phenotypic screening to identify safe and effective M1 PAMs.

  13. Do shrubs reduce the adverse effects of grazing on soil properties?

    Increases in the density of woody plants are a global phenomenon in drylands, and large aggregations of shrubs, in particular, are regarded as being indicative of dysfunctional ecosystems. There is increasing evidence that overgrazing by livestock reduces ecosystem functions in shrublands, but that shrubs may buffer the negative effects of increasing grazing. We examined changes in water infiltration and nutrient concentrations in soils under shrubs and in their interspaces in shrublands in eastern Australia that varied in the intensity of livestock grazing. We used structural equation modelling to test whether shrubs might reduce the negative effects of overgrazing on infiltration and soil carbon and nitrogen (henceforth ‘soil nutrients’). Soils under shrubs and subject to low levels of grazing were more stable and had greater levels of soil nutrients. Shrubs had a direct positive effect on soil nutrients; but, grazing negatively affected nutrients by increasing soil bulk density. Structural equation modelling showed that shrubs had a direct positive effect on water flow under ponded conditions but also enhanced water flow, indirectly, through increased litter cover. Any positive effects of shrubs on water flow under low levels of grazing waned at high levels of grazing. Our results indicate that shrubs may reduce the adverse effects of grazing on soil properties. Specifically, shrubs could restrict access to livestock and therefore protect soils and plants beneath their canopies. Low levels of grazing are likely to ensure the retention of soil water and soil carbon and nitrogen in shrubland soils.

    We were interested in investigating the effects of dance movement therapy (DMT) in a psychiatric outpatient clinic with patients diagnosed with depression. DMT aims to engage the patients in physical and verbal exploration of their experiences generated in movement based interaction. The assumption was that DMT, which includes both physical engagement as well as emotional and social exploration, would alleviate the mood and psychiatric symptoms. All adult patients (n = 33) included in the study received treatment as usual (TAU). Twenty-one patients participated in a 12-session DMT group intervention, and the remaining 12 patients chose to take TAU only. The majority of the patients suffered from moderate or severe depression, recurrent and/or chronic type. The effects of the interventions were investigated after the intervention, and at 3-month follow-up. Compared to the TAU, adding DMT seemed to improve the effect of the treatment. The effect of the DMT was observable whether the patient was taking antidepressant medication or not. At follow-up, between group effect sizes (ES) were medium in favor for the DMT group (d = 0.60–0.79). In the DMT group, the within ES at the 3 months follow-up varied from 0.62 to 0.82 as compared to TAU 0.15–0.37. The results indicated that DMT is beneficial in the treatment of depressed patients.

  16. Adverse Effects of Synthetic Cannabinoids: Management of Acute Toxicity and Withdrawal

    PubMed Central

    2016-01-01

    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

    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.

Two datasets which contain compounds with two serum enzyme markers of liver toxicity: alanine aminotransferase (ALT, n=187) and aspartate aminotransferase (AST, n=209) are analyzed. Statistical quality of the prediction for ALT activity is n=35, Sensitivity = 0.5556, Specificity = 0.8077, and Accuracy = 0.7429. In the case of AST activity the prediction is characterized by n=42, Sensitivity = 0.6875, Specificity = 0.7692, and Accuracy = 0.7381. A number of structural alerts which can be related to the studied activities are revealed. It is the first attempt to build up the classification QSAR model by means of the Monte Carlo technique based on representation of the molecular structure by SMILES using the CORAL software.

    Propolis (bee glue) is the resinous substance that bees collect from living plants for the construction and adaptation of their nests. It has antibacterial, antifungal, and antiviral properties and may have a wide range of other beneficial biological activities. Propolis is available as a dietary supplement, in products for the protection of health and prevention of diseases, in biopharmaceuticals, and as a constituent of (bio)cosmetics. In this article, the following aspects of propolis are reviewed: the nature and chemical composition, its biological properties and applications, contact allergy and allergic contact dermatitis (sensitizing potential, products causing contact allergy, clinical picture, frequency of sensitization, coreactivity and cross-reactivity, the allergens in propolis), and other adverse effects.

    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.

    Sexual assault was a ubiquitous and serious problem in our society. The world's care centers and forensic associations, which were at the forefront of scientific research in sexual assaults, discussed the role of the Forensic Nursing in their early diagnosis and their prevention, but little has been written in literature regarding their appropriate management. This article focuses on the immunochemical laboratory investigation in diagnosis and prevention of its adverse effects in sexual assaults and the role of the Forensic Nursing played in this task. After a careful reading of all the material received from many of the care centers and the associations contacted, a Forensic Nursing Examination Program, with specific immunochemical address, is identified.

    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

    Naltrexone is an opioid receptor antagonist used in the management of alcohol dependence. Although the endogenous opioid system has been implicated in emotion regulation, the effects of mu-opioid receptor blockade on brain systems underlying negative emotional processing are not clear in addiction. Individuals meeting criteria for alcohol dependence alone (n=18, alcohol) and in combination with cocaine and/or opioid dependence (n=21, alcohol/drugs) and healthy individuals without a history of alcohol or drug dependence (n=21) were recruited. Participants were alcohol and drug abstinent before entered into this double-blind, placebo-controlled, randomized, crossover study. Functional magnetic resonance imaging was used to investigate brain response while viewing aversive and neutral images relative to baseline on 50 mg of naltrexone and placebo. We found that naltrexone modulated task-related activation in the medial prefrontal cortex and functional connectivity between the anterior cingulate cortex and the hippocampus as a function of childhood adversity (for aversive versus neutral images) in all groups. Furthermore, there was a group-by-treatment-by-condition interaction in the right amygdala, which was mainly driven by a normalization of response for aversive relative to neutral images under naltrexone in the alcohol/drugs group. We conclude that early childhood adversity is one environmental factor that influences pharmacological response to naltrexone. Pharmacotherapy with naltrexone may also have some ameliorative effects on negative emotional processing in combined alcohol and drug dependence, possibly due to alterations in endogenous opioid transmission or the kappa-opioid receptor antagonist actions of naltrexone.

    BACKGROUND. Obesity is associated with insulin resistance and increased intrahepatic triglyceride (IHTG) content, both of which are key risk factors for diabetes and cardiovascular disease. However, a subset of obese people does not develop these metabolic complications. Here, we tested the hypothesis that people defined by IHTG content and insulin sensitivity as "metabolically normal obese" (MNO), but not those defined as "metabolically abnormal obese" (MAO), are protected from the adverse metabolic effects of weight gain. METHODS. Body composition, multiorgan insulin sensitivity, VLDL apolipoprotein B100 (apoB100) kinetics, and global transcriptional profile in adipose tissue were evaluated before and after moderate (~6%) weight gain in MNO (n = 12) and MAO (n = 8) subjects with a mean BMI of 36 ± 4 kg/m2 who were matched for BMI and fat mass. RESULTS. Although the increase in body weight and fat mass was the same in both groups, hepatic, skeletal muscle, and adipose tissue insulin sensitivity deteriorated, and VLDL apoB100 concentrations and secretion rates increased in MAO, but not MNO, subjects. Moreover, biological pathways and genes associated with adipose tissue lipogenesis increased in MNO, but not MAO, subjects. CONCLUSIONS. These data demonstrate that MNO people are resistant, whereas MAO people are predisposed, to the adverse metabolic effects of moderate weight gain and that increased adipose tissue capacity for lipogenesis might help protect MNO people from weight gain-induced metabolic dysfunction.

    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.

    Although human beings are, by most standards, the most capable agents to search for and detect extraterrestrial life, we are also potentially the most harmful. While there has been substantial work regarding forward contamination with respect to robotic missions, the issue of potential adverse effects on possible indigenous Martian ecosystems, such as biological contamination, due to a human mission has remained relatively unexplored and may require our attention now as this presentation will try to demonstrate by exploring some of the relevant scientific questions, mission planning challenges, and policy issues. An informal, high-level mission planning decision tree will be discussed and is included as the next page of this abstract. Some of the questions to be considered are: (1) To what extent could contamination due to a human presence compromise possible indigenous life forms? (2) To what extent can we control contamination? For example, will it be local or global? (3) What are the criteria for assessing the biological status of Mars, both regionally and globally? For example, can we adequately extrapolate from a few strategic missions such as sample return missions? (4) What should our policies be regarding our mission planning and possible interaction with what are likely to be microbial forms of extraterrestrial life? (5) Central to the science and mission planning issues is the role and applicability of terrestrial analogs, such as Lake Vostok for assessing drilling issues, and modeling techniques. Central to many of the policy aspects are scientific value, international law, public concern, and ethics. Exploring this overall issue responsibly requires an examination of all these aspects and how they interrelate.

    Tobacco is an important cash crop of Pakistan and tremendous amount of irrational pesticides are being used to control insect growth. The frequency of plasma pesticide residues above acceptable daily intake (ADI) and its correlation with biochemical markers for assessment of adverse health effects in the tobacco farmers at district Sawabi, Pakistan was determined. Total 109 adult males consisting of 55 tobacco farmers exposed to pesticides and 54 controls were included. Pesticides residues in blood were analyzed on HPLC and GC-NPD. Plasma butyrylcholinesterase (BChE) was analyzed by Ellman's method. Biochemical markers including serum calcium, phosphorus, urea, creatinine, bilirubin and liver enzymes were measured on Selectra-E auto analyzer. The tobacco farmers had multiple pesticides residues above ADI in their blood consisting of 35 (63%) methomyl; 31 (56%) thiodicarb; 34(62%) cypermethrin; 27 (49%) Imidacloprid; 18 (32%) Methamidophos and 15 (27%) endosulfan. BChE activity was significantly decreased in the pesticides exposed farmers as compared to controls (P<0.001). Plasma biochemical markers including ALT, AST, CK, LDH and phosphate were significantly raised in the pesticides exposed farmers as compared to control group (P<0.001). Total pesticides residues revealed a significant positive correlation with AST (r=0.42), LDH(r= 0.47), ALT (r=0.20) and phosphorus (r=0.51). Excessive exposure to pesticide caused cytotoxic changes in the hepatic and renal biochemical markers which were positively correlated with pesticide residue. Hence these biomarkers might be used in addition to BChE activity for monitoring of adverse effects of pesticides on the health of farm workers. PMID:19079663

    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.

    In April 2010, an explosion on an oil rig in the Gulf of Mexico killed 11 workers, injured 17 workers, and spilled an estimated 185 million gallons of crude oil into the Gulf. Adverse effects on the health of cleanup workers, fishermen, and others as well as on the ecosystem are being studied. This paper reviews published studies of the adverse health effects due to previous oil spills. Acute effects have included: respiratory, eye, and skin symptoms; headache; nausea; dizziness; and tiredness or fatigue. Chronic effects have included: psychological disorders, respiratory disorders, genotoxic effects, and endocrine abnormalities. We also present a systematic approach to evaluating individuals exposed to oil spills.

    To describe the core elements of modern psychiatric rehabilitation. Based on selected examples we describe the discussion about values in mental health care with focus on Europe. We present outcome data from studies, which have tried to implement care structures based on this value discussion. In the second half of the 20th century, mental health care in all European and other high-income countries changed conceptually and structurally. Deinstitutionalisation reduced the number of psychiatric beds and transferred priority to outpatient care and community-based services, but community mental health programs developed differently across and within these countries. High-income countries in Europe continued to invest in costly traditional services that were neither evidence-based nor person-centered by emphasising inpatient services, sheltered group homes and sheltered workshops. We argue that evidence-based, person-centred, recovery-oriented psychiatric rehabilitation offers a parsimonious solution to developing a consensus plan for community-based care in Europe. The challenges to scaling up effective psychiatric rehabilitation services in high-income countries are not primarily a lack of resources, but rather a lack of political will and inefficient use and dysfunctional allocation of resources.

    The exposure of Bufo arenarum embryos to 25 micromol/L 17beta-estradiol (E2) resulted in 100% lethality within 48 hr, whereas 10 micromol//L E2 was the no observed effect concentration value for short-term chronic (7 days) exposure. The toxicity profile curves show that lethal effects were proportional to the E2 concentration and the time of exposure. The E2 uptake resulted in 20.1 ng E2/mg embryo at 8 hr posttreatment, but 67.3% of this value was achieved during the first 30 min of incubation with this estrogen. Regarding metabolism, the embryos synthesize estrone (E1) from E2 by means of 17beta-hydroxysteroid dehydrogenase. Simultaneous treatments of Bufo arenarum embryos with 1 mg/L Cd2+ and 0.1, 1, or 10 micromol/L E2 enhanced the lethality exerted by cadmium in 76.7, 80, and 83.3% of embryos, respectively. The results indicate that estrogenic endocrine disruptors could have an adverse effect on amphibian embryos and enhance the toxic effect of Cd on amphibian embryos. This study points to the possibility of using the AMPHITOX test as a screening method for potential endocrine disruption as well as the combined effects of chemical mixtures. PMID:15175173

    2015-09-01

    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.

    Anxiety and aggression are part of the behavioral repertoire of humans and animals. However, in their exaggerated form both can become maladaptive and result in psychiatric disorders. On the one hand, genetic predisposition has been shown to play a crucial modulatory role in anxiety and aggression. On the other hand, social experiences have been implicated in the modulation of these traits. However, so far, mainly experiences in early life phases have been considered crucial for shaping anxiety-like and aggressive behavior, while the phase of adolescence has largely been neglected. Therefore, the aim of the present study was to elucidate how levels of anxiety-like and aggressive behavior are shaped by social experiences during adolescence and serotonin transporter (5-HTT) genotype. For this purpose, male mice of a 5-HTT knockout mouse model including all three genotypes (wildtype, heterozygous and homozygous 5-HTT knockout mice) were either exposed to an adverse social situation or a beneficial social environment during adolescence. This was accomplished in a custom-made cage system where mice experiencing the adverse environment were repeatedly introduced to the territory of a dominant opponent but had the possibility to escape to a refuge cage. Mice encountering beneficial social conditions had free access to a female mating partner. Afterwards, anxiety-like and aggressive behavior was assessed in a battery of tests. Surprisingly, unfavorable conditions during adolescence led to a decrease in anxiety-like behavior and an increase in exploratory locomotion. Additionally, aggressive behavior was augmented in animals that experienced social adversity. Concerning genotype, homozygous 5-HTT knockout mice were more anxious and less aggressive than heterozygous 5-HTT knockout and wildtype mice. In summary, adolescence is clearly an important phase in which anxiety-like and aggressive behavior can be shaped. Furthermore, it seems that having to cope with challenge during

The purpose of this paper is to sensitize clinicians who prescribe psychiatric drugs to the issues of the psychology of risk, especially as they pertain to the risk of side effects. Specifically, the present analysis focuses on heuristic organization and framing effects that create cognitive biases in medical practice. Our purpose is to increase the awareness of how pharmaceutical companies may influence physicians by framing the risk of medication side effects to favor their products.

    Stigma is a major social barrier that can restrict access to and willingness to seek psychiatric care. Psychiatric consumers may use secrecy and withdrawal in an attempt to cope with stigma. The purpose of this study was to determine the effects of music therapy on self- and experienced stigma in acute care psychiatric inpatients using a randomized design with wait-list control. Participants (N=83) were randomly assigned by cluster to one of three single-session group-based conditions: music therapy, education, or wait-list control. Participants in the music therapy and education conditions completed only posttests while participants in the wait-list control condition completed only pretests. The music therapy condition was a group songwriting intervention wherein participants composed lyrics for "the stigma blues." Results indicated significant differences in measures of discrimination (experienced stigma), disclosure (self-stigma), and total stigma between participants in the music therapy condition and participants in the wait-list control condition. From the results of this randomized controlled investigation, music therapy may be an engaging and effective psychosocial technique to treat stigma. Limitations, suggestions for future research, and implications for clinical practice and psychiatric music therapy research are provided.

    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.

    Objective: To investigate the changes of mestruation patterns and adverse effects during the treatment of levonorgestrel-releasing intrauterine system(LNG-IUS)for symptomatic adenomyosis in a prospective cohort study. Methods: From December, 2006 to December, 2014, patients of symptomatic adenomyosis diagnosed by transvaginal ultrasound in Peking Union Medical College Hospital were given LNG-IUS. Before and after placement of IUS, all patients' parameters were recorded, including carrying status of IUS, symptoms and scores of dysmenorrhea, menstruation scores, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Risk factors for changes of menstruation patterns and adverse effects, and their impact on treatment effects were analyzed. Results: Totally 1 100 cases met inclusion criteria, with median age 36 years(range 20-44 years), median follow-up 35 months(range 1 -108 months). During follow-up changes of menstruation patterns increased significantly with amenorrhea and shortened-menstruation being the most common manifestations. On 3, 6, 12, 24, 36, 48 and 60 months after the placement of LNG-IUS, 0, 5.8%(43/744), 6.9%(47/682), 10.1%(60/595), 17.3%(87/502), 27.2%(104/383)and 29.6%(82/277)patients achieved amenorrhea respectively(P<0.01). Total and subclassification of adverse effects decreased significantly(P<0.01). Within 12 months and >12 months after placement, abdominal pain and body weight increasing ≥5 kg/year were the most common adverse effects. Changes of menstruation patterns, total and subclassifications of adverse effects were neither dependent on patient parameters, treatment modes and treatment effects, nor could predict future LNG-IUS carrying status(all P> 0.05). After taking out of LNG-IUS, most changes of menstruation and adverse effects disappeared. Conclusions: During the treatment of LNG-IUS for symptomatic adenomyosis, changes of menstruation patterns increase gradually with amenorrhea and shortened

    OBJECTIVE: To compare direct and indirect costs of day and inpatient treatment of acute psychiatric illness. DESIGN: Randomised controlled trial with outcome and costs assessed over 12 months after the date of admission. SETTING: Teaching hospital in an inner city area. SUBJECTS: 179 patients with acute psychiatric illness referred for admission who were suitable for random allocation to day hospital or inpatient treatment. 77 (43%) patients had schizophrenia. INTERVENTIONS: Routine inpatient or day hospital treatment. MAIN OUTCOME MEASURES: Direct and indirect costs over 12 months, clinical symptoms, social functioning, and burden on relatives over the follow up period. RESULTS: Clinical and social outcomes were similar at 12 months, except that inpatients improved significantly faster than day patients and burden on relatives was significantly less in the day hospital group at one year. Median direct costs to the hospital were 1923 pounds (95% confidence interval 750 pounds to 3174 pounds) per patient less for day hospital treatment than inpatient treatment. Indirect costs were greater for day patients; when these were included, overall day hospital treatment was 2165 pounds cheaper than inpatient treatment (95% confidence interval of median difference 737 pounds to 3593 pounds). Including costs to informants when appropriate meant that day hospital treatment was 1994 pounds per patient cheaper (95% confidence interval 600 pounds to 3543 pounds). CONCLUSIONS: Day patient treatment is cheaper for the 30-40% of potential admissions that can be treated in this way. Carers of day hospital patients may bear additional costs. Carers of all patients with acute psychiatric illness are often themselves severely distressed at the time of admission, but day hospital treatment leads to less burden on carers in the long term.

    Evidence is accumulating that commonly used pesticides are linked to decline of pollinator populations; adverse effects of three neonicotinoids on bees have led to bans on their use across the European Union. Developing insecticides that pose negligible risks to beneficial organisms such as honeybees is desirable and timely. One strategy is to use recombinant fusion proteins containing neuroactive peptides/proteins linked to a 'carrier' protein that confers oral toxicity. Hv1a/GNA (Galanthus nivalis agglutinin), containing an insect-specific spider venom calcium channel blocker (ω-hexatoxin-Hv1a) linked to snowdrop lectin (GNA) as a 'carrier', is an effective oral biopesticide towards various insect pests. Effects of Hv1a/GNA towards a non-target species, Apis mellifera, were assessed through a thorough early-tier risk assessment. Following feeding, honeybees internalized Hv1a/GNA, which reached the brain within 1 h after exposure. However, survival was only slightly affected by ingestion (LD50>100 µg bee(-1)) or injection of fusion protein. Bees fed acute (100 µg bee(-1)) or chronic (0.35 mg ml(-1)) doses of Hv1a/GNA and trained in an olfactory learning task had similar rates of learning and memory to no-pesticide controls. Larvae were unaffected, being able to degrade Hv1a/GNA. These tests suggest that Hv1a/GNA is unlikely to cause detrimental effects on honeybees, indicating that atracotoxins targeting calcium channels are potential alternatives to conventional pesticides.

    It is known that the adverse effects of shock wave boundary layer interactions in high speed inlets include reduced total pressure recovery and highly distorted flow at the aerodynamic interface plane (AIP). This paper presents a design method for flow control which creates perturbations in geometry. These perturbations are tailored to change the flow structures in order to minimize shock wave boundary layer interactions (SWBLI) inside supersonic inlets. Optimizing the shape of two dimensional micro-size bumps is shown to be a very effective flow control method for two-dimensional SWBLI. In investigating the three dimensional SWBLI, a square duct is employed as a baseline. To investigate the mechanism whereby the geometric elements of the baseline, i.e. the bottom wall, the sidewall and the corner, exert influence on the flow's aerodynamic characteristics, each element is studied and optimized separately. It is found that arrays of micro-size bumps on the bottom wall of the duct have little effect in improving total pressure recovery though they are useful in suppressing the incipient separation in three-dimensional problems. Shaping sidewall geometry is effective in re-distributing flow on the side wall and results in a less distorted flow at the exit. Subsequently, a near 50% reduction in distortion is achieved. A simple change in corner geometry resulted in a 2.4% improvement in total pressure recovery.

    Although maternal stress and depression have been linked to adverse birth outcomes (ABOs), few studies have investigated preventive interventions targeting maternal mental health as a means of reducing ABOs. This randomized controlled study examines the impact of Family Foundations (FF)—a transition to parenthood program for couples focused on promoting coparenting quality, with previously documented impact on maternal stress and depression—on ABOs. We also examine whether intervention buffers birth outcomes from the negative effect of elevated salivary cortisol levels. We use intent-to-treat analyses to assess the main effects of the FF intervention on ABOs (prematurity, birth weight, pregnancy complications, Cesarean section, and days in hospital for mothers and infants) among 148 expectant mothers. We also test the interaction of cortisol with intervention condition status in predicting ABOs. FF participation was associated with reduced risk of C-section (OR .357, p < 0.05, 95 % CI 0.149, 0.862), but did not have main effects on other ABOs. FF significantly buffered (p < 0.05) the negative impact of maternal cortisol on birth weight, gestational age, and days in hospital for infants; that is, among women with relatively higher levels of prenatal cortisol, the intervention reduced ABOs. These results demonstrate that a psycho-educational program for couples reduces incidence of ABOs among higher risk women. Future work should test whether reduced maternal stress and depression mediate these intervention effects. PMID:24969352

    We assessed adverse metabolic effects (AMEs) of atenolol and hydrochlorothiazide (HCTZ) among hypertensive patients with and without abdominal obesity using data from a randomized, open-label study of hypertensive patients without evidence of cardiovascular disease or diabetes. Intervention included randomization to HCTZ 25mg or atenolol 100mg monotherapy followed by their combination. Fasting glucose, insulin, triglycerides, HDL cholesterol and uric acid were measured at baseline and after mono-and combination therapy. Outcomes included new occurrence of and predictors for new cases of glucose ≥ 100mg/dl (impaired fasting glucose [IFG]), triglyceride ≥ 150 mg/dl, HDL ≤ 40mg/dl for men or ≤ 50mg/dl for women, or new onset diabetes according to presence or absence of abdominal obesity. Abdominal obesity was present in 167/395 (58%). Regardless of strategy, in those with abdominal obesity, 20% had IFG at baseline compared with 40% at end of study (p<0.0001). Proportion with triglycerides ≥ 150 mg/dl increased from 33% at baseline to 46% at end of study (p<0.01). New onset diabetes occurred in 13 (6%) with and in 4 (2%) without abdominal obesity. Baseline levels of glucose, triglyceride and HDL predicted adverse outcomes and predictors for new onset diabetes after monotherapy in those with abdominal obesity included HCTZ strategy (OR 47, 95% CI 2.55-862), female sex (OR 31.3, 95% CI 2.10-500) and uric acid (OR 3.2, 95% CI 2.35-7.50). Development of AME, including new onset diabetes associated with short term exposure to HCTZ and atenolol was more common in those with abdominal obesity. PMID:19917874

    The current investigations were undertaken to study the mechanism of the adverse effect of phytoestrogens on the function of bovine granulosa (follicles >1< cm in diameter) and luteal cells from day 1-5, 6-10, 11-15, 16-19 of the oestrous cycle. The cells were incubated with genistein, daidzein or coumestrol (each at the dose of 1 × 10(-6) m). The viability and secretion of estradiol (E2), progesterone (P4) and oxytocin (OT) were measured after 72 h of incubation. Moreover, the expression of mRNA for neurophysin-I/OT (NP-I/OT; precursor of OT) and peptidyl-glycine-α-amidating monooxygenase (PGA, an enzyme responsible for post-translational OT synthesis) was determined after 8 h of treatment. None of the phytoestrogens used affected the viability of cells except for coumestrol. The increased secretion of E2 and P4 was only obtained by coumestrol (p<0.05) from granulosa cells from follicles <1cm in diameter and decreased from luteal cells on days 11-15 of the oestrous cycle, respectively. All three phytoestrogens stimulated (p<0.05) OT secretion from granulosa and luteal cells in all stages of the oestrous cycle and the expression of NP-I/OT mRNA in the both types of cells. The expression of mRNA for PGA was stimulated (p<0.05) by daidzein and coumestrol in granulosa cells, and by genistein and coumestrol in luteal cells. In conclusion, our results demonstrate that these phytoestrogens can impair the ovary function in cattle by adversely affecting the synthesis of OT in follicles and in corpus luteum. However, their influence on the ovarian steroids secretion was less evident.

    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.

    The authors have been following a group of 6 prisoners of war and their families since the men were returned from North Viet Nam. They found that most of the men experiences cognitive, social, work, emotional, and family difficulties during the first two years after their return. However, most of these problems were resolved after two years, and there was no evidence of the concentration camp syndrome, homicidal or suicidal behavior, violent physical aggression, impotence, fugue states, psychosomatic disorders, or major psychiatric illnesses in any of the men. On the basis of their findings, the authors make recommendations for future reentry programs.

    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.

    This study examined the direct and interactive effects of stress reactivity and family adversity on socioemotional and cognitive development in three hundred and thirty-eight 5- to 6-year-old children. Neurobiological stress reactivity was measured as respiratory sinus arrhythmia and salivary cortisol responses to social, cognitive, sensory, and emotional challenges. Adaptation was assessed using child, parent, and teacher reports of externalizing symptoms, prosocial behaviors, school engagement, and academic competence. Results revealed significant interactions between reactivity and adversity. High stress reactivity was associated with more maladaptive outcomes in the context of high adversity but with better adaption in the context of low adversity. The findings corroborate a reconceptualization of stress reactivity as biological sensitivity to context by showing that high reactivity can both hinder and promote adaptive functioning.

    Thalamic deep brain stimulation is a mainstay treatment for severe and drug-refractory essential tremor, but postoperative management may be complicated in some patients by a progressive cerebellar syndrome including gait ataxia, dysmetria, worsening of intention tremor and dysarthria. Typically, this syndrome manifests several months after an initially effective therapy and necessitates frequent adjustments in stimulation parameters. There is an ongoing debate as to whether progressive ataxia reflects a delayed therapeutic failure due to disease progression or an adverse effect related to repeated increases of stimulation intensity. In this study we used a multimodal approach comparing clinical stimulation responses, modelling of volume of tissue activated and metabolic brain maps in essential tremor patients with and without progressive ataxia to disentangle a disease-related from a stimulation-induced aetiology. Ten subjects with stable and effective bilateral thalamic stimulation were stratified according to the presence (five subjects) of severe chronic-progressive gait ataxia. We quantified stimulated brain areas and identified the stimulation-induced brain metabolic changes by multiple (18)F-fluorodeoxyglucose positron emission tomography performed with and without active neurostimulation. Three days after deactivating thalamic stimulation and following an initial rebound of symptom severity, gait ataxia had dramatically improved in all affected patients, while tremor had worsened to the presurgical severity, thus indicating a stimulation rather than disease-related phenomenon. Models of the volume of tissue activated revealed a more ventrocaudal stimulation in the (sub)thalamic area of patients with progressive gait ataxia. Metabolic maps of both patient groups differed by an increased glucose uptake in the cerebellar nodule of patients with gait ataxia. Our data suggest that chronic progressive gait ataxia in essential tremor is a reversible cerebellar

    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

    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

    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

    Thiazolidinediones (TZDs) or glitazones are agents that are widely used for the treatment of type 2 diabetes mellitus. These drugs have a multitude of therapeutic effects including reduction in insulin resistance and hyperglycaemia, anti-inflammatory effects and amelioration of hypertension, microalbuminuria and hepatic steatosis. The TZD molecular target, peroxisome proliferator-activated receptor gamma (PPARgamma), a nuclear transcription factor, is expressed diffusely in humans, including many tissues comprising the cardiovascular and renal systems. This suggests a potential for TZDs to elicit perturbing effects on these systems, which are independent of their effects on glucose and lipid metabolism. One of the most common adverse effects of TZDs is fluid retention, which can result in, or exacerbate, oedema and congestive heart failure (CHF). The frequency of peripheral oedema is approximately 5% when TZDs are used in mono- or combination oral therapy, and about 15% when used with insulin. Patients with type 2 diabetes are at high risk of myriad morbid complications, including CHF. The development of CHF, particularly in the elderly, is a harbinger of premature mortality. TZD-induced oedema is largely peripheral, may have its origins in changes in haemodynamics, with some contribution from molecules, which regulate cell and tissue permeability (e.g. vascular endothelial growth factor and protein kinase Cbeta), and remains the preponderant manifestation of TZD-induced fluid retention even in those with existing heart failure. Preclinical and pilot clinical data attest to the fact that at least part of the fluid retention derives from a direct effect of TZDs on sodium reabsorption via the renal medullary collecting duct, a mechanism that is sensitive to diuretic agents that have this nephron segment as their site of action, in whole or in part (spironolactone, amiloride and hydrochlorothiazide). Our review suggests various potential clinical strategies by which

    Mycorrhizal roots are frequently colonized by fungi of the Phialocephala fortinii s.l.-Acephala applanata species complex (PAC). These ascomycetes are common and widespread colonizers of tree roots. Some PAC strains reduce growth increments of their hosts but are beneficial in protecting roots against pathogens. Nothing is known about the effects of PAC on mycorrhizal fungi and the PAC-mycorrhiza association on plant growth, even though these two fungal groups occur closely together in natural habitats. We expect reduced colonization rates and reduced negative effects of PAC on host plants if roots are co-colonized by an ectomycorrhizal fungus (ECM). Depending on the temperature regime interactions among the partners in this tripartite ECM-PAC-plant system might also change. To test our hypotheses, effects of four PAC genotypes (two pathogenic and two non-pathogenic on the Norway spruce), mycorrhization by Laccaria bicolor (strain S238N) and two temperature regimes (19°C and 25°C) on the biomass of the Douglas-fir (Pseudotsuga menziesii) and Norway spruce (Picea abies) seedlings were studied. Mycorrhization compensated the adverse effects of PAC on the growth of the Norway spruce at both temperatures. The growth of the Douglas-fir was not influenced either by PAC or mycorrhization at 19°C, but at 25°C mycorrhization had a similar protective effect as in the Norway spruce. The compensatory effects probably rely on the reduction of the PAC-colonization density by mycorrhizae. Temperature and the PAC strain only had a differential effect on the biomass of the Norway spruce but not on the Douglas-fir. Higher temperature reduced mycorrhization of both hosts. We conclude that ectomycorrhizae form physical and/or physiological barriers against PAC leading to reduced PAC-colonization of the roots. Additionally, our results indicate that global warming could cause a general decrease of mycorrhization making primary roots more accessible to other symbionts and pathogens.

Temperature and the PAC strain only had a differential effect on the biomass of the Norway spruce but not on the Douglas-fir. Higher temperature reduced mycorrhization of both hosts. We conclude that ectomycorrhizae form physical and/or physiological barriers against PAC leading to reduced PAC-colonization of the roots. Additionally, our results indicate that global warming could cause a general decrease of mycorrhization making primary roots more accessible to other symbionts and

    Background A prolonged corrected QT (QTc) interval is a marker for an increased risk of sudden cardiac death. We evaluated the relationship between oral contraceptive (OC) use, type of OC, and QTc interval. Methods We identified 410,782 ECGs performed at Northern California Kaiser Permanente on female patients between 15–53 years from January, 1995 to June, 2008. QT was corrected for heart rate using log-linear regression. OC generation (first, second and third) was classified by increasing progestin androgenic potency, while the fourth generation was classified as anti-androgenic. Results Among 410,782 women, 8.4% were on OC. In multivariate analysis after correction for comorbidities, there was an independent shortening effect of OCs overall (slope = −0.5ms; SE = 0.12, p<0.0002). Users of first and second generation progestins had a significantly shorter QTc than non-users (p<0.0001), while users of fourth generation had a significantly longer QTc than non-users (slope = 3.6ms, SE = 0.35, p<0.0001). Conclusion Overall, OC use has a shortening effect on the QTc. Shorter QTc is seen with first and second generation OC while fourth generation OC use has a lengthening effect on the QTc. Careful examination of adverse event rates in fourth generation OC users is needed. PMID:23879279

    The manufacture of methamphetamine in clandestine drug laboratories occurs in various locations, including residential houses and apartments. Unlike the controlled manufacture of chemicals and drugs, clandestine manufacture results in the uncontrolled storage, use, generation, and disposal of a wide range of chemicals and the deposit of methamphetamine drug residues on indoor surfaces (1). These residues have been found at high levels on porous and nonporous surfaces and have been shown to persist for months to years (1). Persons exposed to these environments often have poorly defined exposures and health effects. It is commonly assumed that these levels of exposure are low compared with those related to illicit drug use or therapeutic use of amphetamine-based drugs for managing behavioral issues such as attention deficit hyperactivity disorder (2). In 2015, a family that was unknowingly exposed to methamphetamine residues in a house in Australia was found to have adverse health effects and elevated methamphetamine levels in hair samples, highlighting the potential for public health risks for persons who might live in methamphetamine-contaminated dwellings. This case study highlights the importance of the identification and effective decontamination of former clandestine drug laboratories.

    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.

    Calcium polycarbophil is the calcium salt of polyacrylic acid crosslinked with divinyl glycol. It is chemically and physiologically inert. In dilute alkali it possesses marked hydrophilic capacity (60 to 100 times its weight), which is the basis for its therapeutic use. In daily dosages of 4 to 5 g in adults, it appears to be quite safe, is non-toxic, does not interfere with digestion or absorption, and does not cause gastrointestinal irritation. It appears to be effective in the treatment of both constipation and diarrhea due to functional or organic causes. Several days of continuous use are necessary before effectiveness becomes apparent. Clinical studies, of which there are relatively few, range from uncontrolled, unblinded evaluations of an almost anecdotal nature to well controlled, double-blind, crossover studies. Additional carefully controlled studies on dietary influences, exercise, and patient compliance would be helpful. Adverse effects, which are minimal, include epigastric fullness or heaviness, abdominal distention and bloating, and flatulence. As with all bulk-forming agents, calcium polycarbophil should not be used by persons who have stenotic lesions of the gastrointestinal tract.

    Patients with COPD have high risk for osteoporosis and fractures. 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. PMID:19888355

    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.

    Although all Chinese materia medica (CMM) come from nature, CMM interventions have both therapeutic effects and adverse effects (AEs). Normally, AEs in randomized controlled trial (RCT) with traditional Chinese medicine (TCM) could be divided into five types as follows: 1) AEs under proper TCM principles and guidelines, such as the toxicity (acute and chronic) and allergy; 2) AEs due to improper usage without following TCM principles, involving without following the TCM therapeutic principles, over-dosage, improper processing and preparation methods, improper formula strategy, etc; 3) AEs due to contamination in CMM, such as heavy metal and pesticides contaminations in Chinese herbal medicine interventions, and intentional or unintentional contamination with drug(s); 4) AEs due to replacement of CMMs; 5) AEs due to drug-herb interaction. AEs of TCM should be treated properly. Overestimation or underestimation about AEs of TCM intervention will bring a wrong message to patients and health care providers. In order to give readers a more comprehensive understanding about the safety issue of study intervention, Consolidated Standards of Reporting Trials (CONSORT) for TCM should involve the background information on side effects of each CMM constituents and/or the study intervention, specific outcome assessment on AEs, the details of reported AEs and the interpretation of the AEs occurrence in a structural RCT report.

    Summary This study was conducted to evaluate the adverse effects of the anabolic steroid, boldenone undecylenate (BOL) on reproductive functions of male rabbits. Thirty white New Zealand mature male rabbits were divided into three groups (10 rabbits each). Group A rabbits served as a control group. Group B rabbits received 4.4 mg/kg body weight (bwt) BOL 5% oily solution. Group C rabbits received 8.8 mg/kg bwt BOL. Rabbits were injected intramuscularly twice weekly for two months. BOL had no significant effect on the bwt and bwt gain. Testes and epididymis weights were decreased significantly in the BOL-treated groups. BOL caused significant reduction in serum testosterone level, seminal volume, sperm motility, and sperm count. No abnormalities were detected in the sperm morphology of the BOL-treated groups. Histopathological alterations in the testes and epididymis were marked in the group C rabbits. These results indicate that administration of BOL exerts a significant harmful effect on the reproductive functions of male rabbits. PMID:22583130

    We evaluated the cost-effectiveness of one-time pharmacogenomic testing for preventing adverse drug reactions (ADRs) over a patient's lifetime. We developed a Markov-based Monte Carlo microsimulation model to represent the ADR events in the lifetime of each patient. The base-case considered a 40-year-old patient. We measured health outcomes in life years (LYs) and quality-adjusted LYs (QALYs) and estimated costs using 2013 US$. In the base-case, one-time genetic testing had an incremental cost-effectiveness ratio (ICER) of $43,165 (95% confidence interval (CI) is ($42,769,$43,561)) per additional LY and $53,680 per additional QALY (95% CI is ($53,182,$54,179)), hence under the base-case one-time genetic testing is cost-effective. The ICER values were most sensitive to the average probability of death due to ADR, reduction in ADR rate due to genetic testing, mean ADR rate and cost of genetic testing.

    In this study, the effect of phytic acid supplement on streptozotocin-induced diabetic rats was investigated. Diabetic rats were fed rodent chow with or without phytic acid supplementation for thirty days. Blood and organ samples were collected for assays. The average food intake was the highest and the body weight gain was the lowest in the group fed phytic acid supplement compared to the diabetic and normal control groups. There was a downward trend in intestinal amylase activity in the group fed phytic acid supplement compared to the other groups. The spike in random blood glucose was the lowest in the same group. We noted reduced serum triglycerides and increased total cholesterol and HDL cholesterol levels in the group fed phytic acid supplement. Serum alkaline phosphatase and alanine amino transferase activities were significantly (P < 0.05) increased by phytic acid supplementation. Systemic IL-1 β level was significantly (P < 0.05) elevated in the diabetic control and supplement treated groups. The liver lipogenic enzyme activities were not significantly altered among the groups. These results suggest that phytic acid supplementation may be beneficial in the management of diabetes mellitus. The observed adverse effect on the liver may be due to the combined effect of streptozotocin-induced diabetes and phytic acid supplementation.

    Although there is accumulating evidence regarding the additional protective effect of folic acid against adverse pregnancy outcomes other than neural tube defects, these effects have not been elucidated in detail. We evaluated whether folic acid supplementation is associated with favorable maternal and fetal outcomes. This was a secondary analysis of 215 pregnant women who were enrolled in our prior study. With additional data from telephone interviews regarding prenatal folic acid supplementation, existing demographic, maternal and fetal data were statistically analyzed. The concentration of folic acid in maternal blood was significantly higher following folic acid supplementation (24.6 ng/mL vs.11.8 ng/mL). In contrast, homocysteine level in maternal blood decreased with folic acid supplementation (5.5 µmol/mL vs. 6.8 µmol/mL). The rates of both preeclampsia (odds ratio [OR], 0.27; 95% confidence interval [CI], 0.09–0.76) and small for gestational age (SGA; 9.2% vs. 20.0%; OR, 0.42; 95% CI, 0.18–0.99) were lower in the folic acid supplementation group than those in the control group. Other pregnancy outcomes had no association with folic acid supplementation. The findings indicate that folic acid supplementation may help to prevent preeclampsia and SGA. Further studies are warranted to elucidate the favorable effects of folic acid supplementation on pregnancy outcomes. PMID:24842467

    Little is known about the acceptability of wearing physical activity-monitoring devices. This study aimed to examine the compliance, comfort, incidence of adverse side effects, and usability when wearing the SenseWear Armband (SWA) for daily physical activity assessment. In a prospective study, 314 participants (252 people with COPD, 36 people with a dust-related respiratory disease and 26 healthy age-matched people) completed a purpose-designed questionnaire following a 7-day period of wearing the SWA. Compliance, comfort levels during the day and night, adverse side effects and ease of using the device were recorded. Non-compliance with wearing the SWA over 7 days was 8%. The main reasons for removing the device were adverse side effects and discomfort. The SWA comfort level during the day was rated by 11% of participants as uncomfortable/very uncomfortable, with higher levels of discomfort reported during the night (16%). Nearly half of the participants (46%) experienced at least one adverse skin irritation side effect from wearing the SWA including itchiness, skin irritation and rashes, and/or bruising. Compliance with wearing the SWA for measurement of daily physical activity was found to be good, despite reports of discomfort and a high incidence of adverse side effects.

    Health care workers are often exposed to violence and aggression in psychiatric settings. Short-term risk assessments, such as the Brøset Violence Checklist (BVC), are strong predictors of such aggression and may enable staff to take preventive measures against aggression. This study evaluated whether the routine use of the BVC could reduce the frequency of patient aggression. We conducted a study with a semi-random regression discontinuity design in 15 psychiatric wards. Baseline aggression risk was assessed using the Aggression Observation Short Form (AOS) over three months. The BVC was implemented in seven intervention wards, and the risk of aggressive incidents over three months of follow-up was compared with the risk in eight control wards. The analysis was conducted at the ward level because each ward was allocated to the intervention and control groups. At baseline, the risk of aggression varied between wards, from one aggressive incident per patient per 1,000 shifts to 147 aggressive incidents per patient per 1,000 shifts. The regression discontinuity analysis found a 45% reduction in the risk of aggression (Odds Ratio (OR) = 0.55, 95% confidence interval: 0.21-1.43). The study did not find a significant reduction in the risk of aggression after implementing a systematic short-term risk assessment with the BVC. Although our findings suggest that use of the BVC may reduce the risk of aggression, the results need to be confirmed in studies with more statistical power.

    Cationic compounds are diverse and atypical therapeutic substances. In the present study we examined whether a prototypical class effect of cationic drugs in the cardiovascular system exists and whether this might be predictable on the basis of chemistry. The dose-dependent effects of cationic compounds of varying molecular weights and charge were examined on the blood pressure (BP), heart rate (HR) and the ECG in anesthetized rats. The compounds examined were protamine, hexadimethrine, tetraethylammonium (TEA), low molecular weight poly-L-lysine (LMW-PLL) and high molecular weight PLL (HMW-PLL). All of the compounds examined except TEA produced a dose-dependent reduction in BP. No changes occurred in HR even when high doses were administered. The ECG effects of these cationic compounds included a dose-dependent prolongation of the QT interval, especially at higher doses. All compounds transiently decreased the size of the P-wave after i.v. bolus administration whereas only protamine and hexadimethrine prolonged the PR and QRS intervals and only at the highest dose (32 mg/kg) administered. All cationic compounds, except TEA and saline, evoked ventricular premature beats (VPB), and protamine and HMW-PLL also evoked brief episodes of ventricular tachycardia (VT). The incidence and frequency of arrhythmias was not dose-dependent and no animals experienced protracted episodes of arrhythmia incidence. These dose dependent effects of the polycationic compounds tested suggest a collective mechanism of action that relates the effect of charge of the compound to the onset and persistence of observed cardiovascular toxicity, and adverse cardiovascular effect risk appears to be predictable on this basis.

    Raloxifene is the only selective estrogen receptor modulator approved for long-term treatment in the prevention of osteoporotic fractures and for the reduction of invasive breast cancer risk in post-menopausal women. The demonstrated beneficial effects on bone and mammalian tissue led clinical and molecular research to focus mainly on these organs, giving less attention to all other systemic effects. The aim of this review was to evaluate all described systemic effects of raloxifene, investigating its molecular and tissutal mechanism of action. A literature research was carried out in electronic databases MEDLINE, EMBASE, ScienceDirect, and the Cochrane Library in interval time between 2000 and 2012. Outcomes were considered in relation to positive/adverse effects concerning bone metabolism, lipid metabolism, coagulation pattern, menopausal symptoms, breast cancer onset, and endometrial cancer onset. Raloxifene acts as an estrogen agonist or antagonist depending on the tissue. This feature is related to specific actions on at least 2 distinct estrogen receptors, whose proportions vary according to tissue type. Raloxifene is a drug for the treatment of osteoporosis and for the prevention of estrogen receptor-positive breast cancer because it guarantees a safety profile on the endometrium. Raloxifene is furthermore an effective therapy in women with increased levels of plasma cholesterol. Raloxifene treatment shifts the coagulation pattern toward prothrombosis, and the patients should be exhaustively informed about the risks associated with therapy. Raloxifene does not show to affect memory and cognition. Finally, it is noteworthy that quality-of-life studies demonstrated some favorable effects of raloxifene.

    Research into therapeutics for neuropsychiatric disorders is increasingly focusing on drugs with new mechanisms of action, and such agents are often assessed in preclinical studies using nonhuman primates. However, researchers lack a standardised method to compare different drugs for common adverse effects on the nervous system. We have developed a new scale for this purpose, named "Drug Effects on the Nervous System" (DENS), and tested its utility in an analysis of the second-generation antipsychotic risperidone in monkeys. The behavioural effects of risperidone over a ten-fold clinically relevant exposure range were rated with the DENS scale and compared with a standard motor disability scale for primates. The ratings were correlated with projected D2 and 5-HT2A receptor occupancies over time. The DENS scale detected dose-dependent side effects of risperidone in addition to the motor effects detected with the motor disability scale, including cognitive, sensorimotor and autonomic functions. A consistent temporal association between the DENS scale changes and the projected D2 receptor occupancy was observed, and the DENS scale ratings demonstrated high inter-rater reliability. These results demonstrate the usefulness of the DENS scale as a highly sensitive, reliable and accurate method to identify common adverse effects of risperidone and potentially other neurotropics for translational studies in primates.

    Selective Serotonin Reuptake Inhibitors (SSRIs) have become the drug of choice for the treatment of depression and have shown to be effective in the treatment for other mental disorders. Recently, several articles have reported about the adverse effects observed in newborns after maternal exposure to these drugs during the last trimester of pregnancy. In this work, a review of literature is presented, regarding the above mentioned adverse effects. Moreover, some guidelines for the rational use of these drugs during the last trimester of pregnancy and for the management of prenatally exposed newborns are provided.

    Fluorescence in situ hybridization with chromosome-specific composite DNA probes (``chromosome painting``) is a reliable and efficient method for detecting structural chromosome aberrations. Painting is now being used to quantify chromosome damage in many human populations. In one such study we evaluated 91 unexposed people ranging in age from birth (cord bloods) to 79. We established a baseline frequency of stable aberrations that showed a highly significant curvi-linear increase with age (p < 0.00001) that accounted for 70% of the variance between donors. The magnitude of this effect illustrates the importance of understanding the cytogenetic changes that occur with age, which is particularly important for quantifying the effects of prior adverse environmental, occupational, or accidental exposure. In this paper we use the data obtained in our previous study to characterize the distribution of stable aberrations by age and pack-years of cigarette smoking. We also provide estimates of the number of cell equivalents that need to be scored to detect a given increase in aberrations above the background level surveyed in this population.

    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.

    Bullous pemphigoid (BP) is the most common autoimmune bullous disease. It primarily presents in elderly patients older than 70 years of age. The presentation can vary with localized or generalized disease that variably affects mucosal tissue. Therapy primarily consists of administration of topical and systemic corticosteroids. Topical corticosteroids are effective with less adverse effects compared with systemic steroids. Other therapies, such as steroid-sparing agents and plasma exchanges, have been recommended and studied to some degree, but these require more evidence before they can be routinely recommended. A 68-year-old African-American female resident of a nursing facility develops a rash and is evaluated at a dermatology clinic. Since the resident has many medications and concomitant diseases, the physician at first suspected a drug rash. On subsequent visits, the resident undergoes multiple punch biopsies and is diagnosed with BP. Treatment is initiated with topical steroids, systemic steroids, and oral minocycline. On a follow-up visit, the resident is showing improvement of her BP. However, the resident's hypertension and hyperglycemia are now uncontrolled as a result of the discontinuation of hydrochlorothiazide and the initiation of steroid therapy. This case highlights the dangers of corticosteroids in patients, especially the elderly, who have multiple comorbidities.

  19. Systemic effects of periodontitis: Lessons learned from research on atherosclerotic vascular disease and adverse pregnancy outcomes

    Studies conducted over the past 25 years have focused on the role of periodontitis, an inflammatory condition of microbial etiology that destroys the tooth supporting tissues, as a systemic inflammatory stressor that can act as an independent risk factor of atherosclerotic vascular disease (AVSD) and adverse pregnancy outcomes (APOs). It has been suggested that periodontitis-associated bacteremias and systemic dissemination of inflammatory mediators produced in the periodontal tissues may result in systemic inflammation and endothelial dysfunction, while bacteria of oral origin may translocate into the feto-placental unit. Epidemiologic studies largely support an association between periodontitis and ASVD / APOs independent of known confounders; indeed, periodontitis has been shown to confer statistically significantly elevated risk for clinical events associated with ASVD and APOs in multivariable adjustments. On the other hand, intervention studies demonstrate that although periodontal therapy reduces systemic inflammation and improves endothelial function, it has no positive effect on the incidence of APOs. Studies of the effects of periodontal interventions on ASVD-related clinical events are lacking. This review summarizes key findings from mechanistic, association and intervention studies and attempts to reconcile the seemingly contradictory evidence that originates from different lines of investigation.

    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-1beta, interleukin-6 and TNF-alpha 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.

    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 been prospectively shown to cause decreased lean muscle mass, increased fat mass, weight gain, increased cholesterol and triglycerides, insulin resistance, and loss of bone mineral density. In population-based analyses it has been associated with an increased incidence of diabetes, clinical fractures, and cardiovascular disease. Data-driven recommendations for managing these adverse effects are needed. Currently the authors advocate the use of adapted practice guidelines developed to prevent diabetes, fractures, and coronary heart disease in the general population. PMID:20141678

    People with mental illness (PWMI) are faced with a number of social and health-related challenges especially stigma and discrimination which tend to have negative effects on their lives. This paper presents narrative monologues portraying the experiences and effects of psychiatric stigma and discrimination on PWMI in South Africa. These narratives voice out the concerns of the stigmatizers (specifically family members and significant others of PWMI) and the stigmatized in a poetic fashion. The society is still not very sympathetic to the plights of PWMI and this affects their general health and well-being. Traditional beliefs and prejudice still drive public attitude towards PWMI especially in African settings. These narratives presented in a poetic fashion in this paper highlight some salient issues relating to the experience and effects of stigma and the desires of PWMI to be treated with love and respect and helped to lead healthy normal lives.

    The American Thoracic Society has previously published statements on what constitutes an adverse effect on health of air pollution in 1985 and 2000. We set out to update and broaden these past statements that focused primarily on effects on the respiratory system. Since then, many studies have documented effects of air pollution on other organ systems, such as on the cardiovascular and central nervous systems. In addition, many new biomarkers of effects have been developed and applied in air pollution studies.This current report seeks to integrate the latest science into a general framework for interpreting the adversity of the human health effects of air pollution. Rather than trying to provide a catalogue of what is and what is not an adverse effect of air pollution, we propose a set of considerations that can be applied in forming judgments of the adversity of not only currently documented, but also emerging and future effects of air pollution on human health. These considerations are illustrated by the inclusion of examples for different types of health effects of air pollution.

    Reproductive toxicity was investigated in rats after developmental exposure to a mixture of 13 endocrine-disrupting contaminants, including pesticides, plastic and cosmetic ingredients, and paracetamol. The mixture was composed on the basis of information about high-end human exposures, and the dose levels reflecting 100, 200, and 450 times this exposure were tested. The compounds were also grouped according to their estrogenicity or anti-androgenicity, and their joint effects were tested at two different doses, with each group reflecting 200 or 450 times human exposure. In addition, a single paracetamol dose was tested (350 mg/kg per day). All exposures and a vehicle were administered by oral gavage to time-mated Wistar dams rats throughout gestation and lactation, and their offspring were assessed for reproductive effects at birth and in prepuberty. The mixture doses, which included the anti-androgenic compounds, affected the male offspring by causing decreased anogenital distance, increased nipple retention (NR), and reduced ventral prostate weights, at both medium and high doses. In addition, the weights of the levator ani/bulbocavernosus muscle (LABC) were decreased at the high dose of anti-androgen mixture. No effects were seen after exposure to the estrogenic chemicals alone, whereas males exposed solely to paracetamol showed decreased LABC weights and increased NR. Thus adverse reproductive effects were observed at mixtures reflecting 200 times high-end human exposure, which is relatively close to the safety margin covered by the regulatory uncertainty factor of 100. This suggests that highly exposed human population groups may not be sufficiently protected against mixtures of endocrine-disrupting chemicals.
