    To review immune checkpoint inhibitor indications and ophthalmic side effects. A literature review was performed using a PubMed search for publications between 1990 and 2017. Immune checkpoint inhibitors are designed to treat system malignancies by targeting one of three ligands, leading to T-cell activation for attack against malignant cells. These ligands (and targeted drug) include cytotoxic T-lymphocyte antigen-4 (CTLA-4, ipilimumab), programmed death protein 1 (PD-1, pembrolizumab, nivolumab), and programmed death ligand-1 (PD-L1, atezolizumab, avelumab, durvalumab). These medications upregulate the immune system and cause autoimmune-like side effects. Ophthalmic side effects most frequently manifest as uveitis (1%) and dry eye (1-24%). Other side effects include myasthenia gravis (n = 19 reports), inflammatory orbitopathy (n = 11), keratitis (n = 3), cranial nerve palsy (n = 3), optic neuropathy (n = 2), serous retinal detachment (n = 2), extraocular muscle myopathy (n = 1), atypical chorioretinal lesions (n = 1), immune retinopathy (n = 1), and neuroretinitis (n = 1). Most inflammatory side effects are managed with topical or periocular corticosteroids, but advanced cases require systemic corticosteroids and cessation of checkpoint inhibitor therapy. Checkpoint inhibitors enhance the immune system by releasing inhibition on T cells, with risk of autoimmune-like side effects. Ophthalmologists should include immune-related adverse events in their differential when examining cancer patients with new ocular symptoms.

    To examine the effects of using positive or negative frames to describe influenza vaccine benefits and side effects on patients' expectations, decisions, decisional conflict, and reported side effects. 292 previously unimmunized patients with chronic respiratory or cardiac disease were randomly assigned to receive benefit/risk information that was framed: (1) positively as the percentage who remain free of influenza and have no vaccine side effects, or (2) negatively as the percentage who acquire influenza and have vaccine side effects. Questionnaires elicited expectations, decisions, and decisional conflict. Vaccines were telephoned 3 days later for a self-report of local and systemic side effects and work absenteeism. Both groups had similar immunization rates and decisional conflict scores. The positive frame group had lower and more realistic expectations of vaccine side effects, fewer systemic side effects, and less work absenteeism (p framing did not influence patients' decisions, possibly due to the patients' awareness of their higher risk of influenza complications and greater desire to follow recommendations. The common practice of using negative frames when describing probabilities of side effects may need to be reexamined, considering its deleterious influence on self-reported side effects and work absenteeism.

    Full Text Available Topical Imiquimod is increasingly used in the treatment of lentigo maligna (LM for patients not suitable or willing for surgery. It acts as an immune response modifier and is recommended for use with caution in patients with autoimmune disorders. A review of the literature did not reveal any reported cases of Idiopathic Thrombocytopenic Purpura (ITP with the use of Imiquimod so far. We report a case of a 55-year-old woman with a history of Addison's and Graves' disease who had been diagnosed with lentigo maligna on the right nasal ala. Within two days of commencing of topical Imiquimod treatment, she was admitted to the hospital with extensive cutaneous and mucosal bruising and treated as acute Idiopathic Throbocytopenic Purpura. Deranged platelets were reversed promptly with treatment and Imiquimod discontinued. We demonstrate that Idiopathic Throbocytopenic Purpura is a potential life-threatening side effect of Imiquimod treatment and patients who have autoimmune disorders are at increased risk of developing this side effect. We recommend that Imiquimod is contraindicated in patients with autoimmune disease. Here we describe the clinical presentation and review the relevant literature on Imiquimod treatment for lentigo maligna and its potential side effects.

  6. Innate Immune Response and Off-Target Mis-splicing Are Common Morpholino-Induced Side Effects in Xenopus.

    Gentsch, George E; Spruce, Thomas; Monteiro, Rita S; Owens, Nick D L; Martin, Stephen R; Smith, James C

    2018-03-12

    Antisense morpholino oligomers (MOs) have been indispensable tools for developmental biologists to transiently knock down (KD) genes rather than to knock them out (KO). Here we report on the implications of genetic KO versus MO-mediated KD of the mesoderm-specifying Brachyury paralogs in the frog Xenopus tropicalis. While both KO and KD embryos fail to activate the same core gene regulatory network, resulting in virtually identical morphological defects, embryos injected with control or target MOs also show a systemic GC content-dependent immune response and many off-target splicing defects. Optimization of MO dosage and increasing incubation temperatures can mitigate, but not eliminate, these MO side effects, which are consistent with the high affinity measured between MO and off-target sequence in vitro. We conclude that while MOs can be useful to profile loss-of-function phenotypes at a molecular level, careful attention must be paid to their immunogenic and off-target side effects.

    2011-03-21

    When the incidence and prevalence of most common vaccine preventable childhood infectious diseases are constantly low, as is the case in many industrialized countries, the incidence of vaccine-associated side effects might become a key determinant in vaccine demand. We study an SIR transmission model with dynamic vaccine demand based on an imitation mechanism where the perceived risk of vaccination is modelled as a function of the incidence of vaccine side effects. The model shows some important differences compared to previous game dynamic models of vaccination, and allows noteworthy inferences as regards both the past and future lifetime of vaccination programmes. In particular it is suggested that a huge disproportion between the perceived risk of disease and vaccination is necessary in order to achieve high coverages. This disproportion is further increased in highly industrialised countries. Such considerations represent serious challenges for future vaccination programmes. Copyright © 2010 Elsevier Ltd.

    2015-01-01

    A study of psychoanalysis from the perspective of side effects reveals that its history was a succession of measures to deal with its own side effects. This, however, does not merely suggest that, as a treatment method, psychoanalysis is incomplete and weak: rather, its history is a record of the growth and development of psychoanalysis that discovered therapeutic significance from phenomena that were initially regarded as side effects, made use of these discoveries, and elaborated them as a treatment method. The approach of research seen during the course of these developments is linked to the basic therapeutic approach of psychoanalysis. A therapist therefore does not draw conclusions about a patient's words and behaviors from a single aspect, but continues to make efforts to actively discover a variety of meanings and values from them, and to make the patient's life richer and more productive. This therapeutic approach is undoubtedly one of the unique aspects of psychoanalysis. I discuss the issue of psychoanalysis and side effects with the aim of clarifying this unique characteristic of psychoanalysis. The phenomenon called resistance inevitably emerges during the process of psychoanalytic treatment. Resistance can not only obstruct the progress of therapy; it also carries the risk of causing a variety of disadvantages to the patient. It can therefore be seen as an adverse effect. However, if we re-examine this phenomenon from the perspective of transference, we find that resistance is in fact a crucial tool in psychoanalysis, and included in its main effect, rather than a side effect. From the perspective of minimizing the character of resistance as a side effect and maximizing its character as a main effect, I have reviewed logical organization, dynamic evaluation, the structuring of treatment, the therapist's attitudes, and the training of therapists. I conclude by stating that psychoanalysis has aspects that do not match the perspective known as a side

  9. Metabolic Side Effects of Lithium

    Directory of Open Access Journals (Sweden)

    2010-04-01

    Full Text Available Lithium is an alkaline ion being used since 19th century. After its widespread use in psychiatric disorders, observed side effects caused skepticism about its therapeutic efficacy. Despite several disadvantages, lithium is one of the indispensible drugs used in affective disorders, especially in bipolar disorder. It became a necessity for physicians to recognize its side effects since lithium is still accepted as a gold standard in the treatment of bipolar disorder. Adverse effects of chronic administration of lithium on several organ systems are widely known. In this article metabolic effects of lithium on thyroid and parathyroid glands, body mass index and kidneys will be discussed along with their mechanisms, clinical findings, possible risk factors and treatment. One of the most common side effect of lithium is hypothyroidism. It has the same clinical and biochemical properties as primary hypothyroidism and observed as subclinical hypothyroidism in the first place. Hypothyroidism, even its subclinical form, may be associated with non-response or inadequate response and is indicated as a risk factor for development of rapid cycling bipolar disorder. Therefore, hypothyroidism should be screened no matter how severe it is and should be treated with thyroid hormone in the presence of clinical hypothyroidism. Weight gain due to lithium administration disturbs the compliance to treatment and negatively affects the course of the illness. Increased risk for diabetes, hypertension, ischemic heart disease and stroke because of weight gain constitute other centers of problem. Indeed, it is of importance to determine the risk factors before treatment, to follow up the weight, to re-organize nutritional habits and to schedule exercises. Another frequent problematic side effect of lithium treatment is renal dysfunction which clinically present as nephrogenic diabetes insipidus with the common symptoms of polyuria and polydipsia. Nephrogenic diabetes

    Caused by the consumption of raw or undercooked freshwater fish containing infective metacercariae of Clonorchis sinensis, human clonorchiasis remains a major public health problem in China. In previous study, we had expressed enolase from C. sinensis (CsENO) on the surface of Bacillus subtilis spore and the recombinant spore induced a pronounced protection in terms of reduced worm burden and eggs per gram feces, suggesting B. subtilis spore as an ideal vehicle for antigen delivery by oral treatment and CsENO as a promising vaccine candidate against clonorchiasis. In the current study, we detected CsENO-specific IgG and IgA levels both in serum and in intestinal mucus from rats orally administrated with B. subtilis spore surface expressing CsENO by ELISA. Lysozyme levels in serum and in intestinal mucus were analyzed too. In addition, IgA-secreting cells in intestine epithelium of the rats were detected by immunohistochemistry assay. The intestinal villi lengths of duodenum, jejunum, and ileum were also measured. Rats orally treated with B. subtilis spore or normal saline were used as controls. Our results showed that, compared with the control groups, oral administration of B. subtilis spore expressing CsENO induced both systemic and local mucosal immune response. The recombinant spores also enhanced non-specific immune response in rats. The spores had no side effect on liver function. Moreover, it might facilitate food utilization and digestion of the rats. Our work will pave the way to clarify the involved mechanisms of protective efficacy elicited by B. subtilis spore expressing CsENO and encourage us to carry out more assessment trails of the oral treated spore to develop vaccine against clonorchiasis.

    2002-01-01

    Full Text Available Vancomycin has been used with increased frequency during the past 15 years and the most common toxicity with this drug is the "red man syndrome". Other adverse effects include neutropenia, fever, phlebitis, nephrotoxicity, ototoxicity, thrombocytopenia, interstitial nephritis, lacrimation, linear IgA bullous dermatosis, necrotizing cutaneous vasculitis and toxic epidermal necrolysis. Only two cases of vancomycin-induced Stevens-Johnson syndrome and one case of pancytopenia have been reported in the medical literature. The treatment for both situations is based on cessation of the vancomycin therapy; in cases of Stevens-Johnson syndrome, antihistamine and/or steroid agents can be used. This article reports a case of pancytopenia and a case of erythema major associated with neutropenia.

  18. The Social Side Effects of Acetaminophen

    Science.gov (United States)

    Mischkowski, Dominik

    About 23% of all adults in the US take acetaminophen during an average week (Kaufman, Kelly, Rosenberg, Anderson, & Mitchell, 2002) because acetaminophen is an effective physical painkiller and easily accessible over the counter. The physiological side effects of acetaminophen are well documented and generally mild when acetaminophen is consumed in the appropriate dosage. In contrast, the psychological and social side effects of acetaminophen are largely unknown. Recent functional neuroimaging research suggests that the experience of physical pain is fundamentally related to the experience of empathy for the pain of other people, indicating that pharmacologically reducing responsiveness to physical pain also reduces cognitive, affective, and behavioral responsiveness to the pain of others. I tested this hypothesis across three double-blind between-subjects drug intervention studies. Two experiments showed that acetaminophen had moderate effects on empathic affect, specifically personal distress and empathic concern, and a small effect on empathic cognition, specifically perceived pain, when facing physical and social pain of others. The same two experiments and a third experiment also showed that acetaminophen can increase the willingness to inflict pain on other people, i.e., actual aggressive behavior. This effect was especially pronounced among people low in dispositional empathic concern. Together, these findings suggest that the physical pain system is more involved in the regulation of social cognition, affect, and behavior than previously assumed and that the experience of physical pain and responsiveness to the pain of others share a common neurochemical basis. Furthermore, these findings suggest that acetaminophen has unappreciated but serious social side effects, and that these side effects may depend on psychological characteristics of the drug consumer. This idea is consistent with recent theory and research on the context-dependency of neurochemical

    1989-01-01

    Side effect incidences after ambulatory (22G needle and two h bed rest) and after non-ambulatory (22 and 20G needles and 20 h bed rest) lumbar iohexol myelography have been estimated and compared. Headache incidence was significantly greater in ambulatory (50%, n=107) as compared to nonambulatory myelography (26%, n=58). Headaches in the ambulatory group tended to be of shorter duration and the difference between severe headaches in ambulatory and non-ambulatory groups was not significant. Serious adverse reactions did not occur and none of the ambulatory patients required readmission because of side effects. The headache was predominantly postural and occurred significantly earlier in the ambulatory group. Headache incidence was significantly greater after 20G needle myelography (44%, n=97) as compared to 22G needle iohexol myelography (26%, n=58). The results support the hypothesis that CSF leakage is a major cause of headache after lumbar iohexol myelography. (orig.)

    Sand, T.; Stovner, L.J.; Myhr, G.; Dale, L.G.

    1990-01-01

    Side effects of iohexol lumbar myelography have been analyzed with respect to the influence of the type of radiological abnormality, sex and age in a group of 200 patients. Headache, postural headache, nausea and back/leg pain were significantly more frequent in patients without definite radiological abnormalities. Postural headache, nausea, dizziness and mental symptoms were more frequent in women, while headache, postural headache, nausea, dizziness, minor mental symptoms (i.e. anxiety or depression) and pain became less frequent with age. This pattern is similar to that reported after lumbar puncture. Young women without definite clinical signs of nerve root lesions probably have the greatest risk of experiencing side effects after iohexol lumbar myelography. (orig.)

    Chlamydia trachomatis (CT) infection is one of the most common causes of reproductive tract diseases and infertility. CT-Hsp60 is synthesized during infection and is released in the bloodstream. As a consequence, immune cells will produce anti-CT-Hsp60 antibodies. Hsp60, a ubiquitous and evolutionarily conserved chaperonin, is normally sequestered inside the cell, particularly into mitochondria. However, upon cell stress, as well as during carcinogenesis, the chaperonin becomes exposed on the cell surface (sf-Hsp60) and/or is secreted from cells into the extracellular space and circulation. Reports in the literature on circulating Hsp and anti-Hsp antibodies are in many cases short on details about Hsp60 concentrations, and about the specificity spectra of the antibodies, their titers, and their true, direct, pathogenetic effects. Thus, more studies are still needed to obtain a definitive picture on these matters. Nevertheless, the information already available indicates that the concurrence of persistent CT infection and appearance of sf-Hsp60 can promote an autoimmune aggression towards stressed cells and the development of diseases such as autoimmune arthritis, multiple sclerosis, atherosclerosis, vasculitis, diabetes, and thyroiditis, among others. At the same time, immunocomplexes composed of anti-CT-Hsp60 antibodies and circulating Hsp60 (both CT and human) may form deposits in several anatomical locations, e.g., at the glomerular basal membrane. The opposite side of the coin is that pre-tumor and tumor cells with sf-Hsp60 can be destroyed with participation of the anti-Hsp60 antibody, thus stopping cancer progression before it is even noticed by the patient or physician.

    Anabolic - androgenic steroids (AAS) were originally developed to promote growth of skeletal muscle. AAS abuse is commonly associated with bodybuilders, weightlifters, and other athletes. The issue of AAS toxicity is not yet completely understood since the adverse effects outline a varied scenario with side effects reported affecting many organs and systems in humans. The true incidence of AAS related medical problems is not known, due to several drawbacks in human studies. The entity of side effects depends on the sex, the dose, the duration of treatment, whether they are taken during exercise training or under sedentary conditions, and the susceptibility of the individuals themselves to androgen exposure partly depending on genetic factors. Both the acute and the chronic effects can lead to toxicity, but generally the serious and even fatal effects depend on the time and the duration of AAS administration. A limitation of human studies is represented by the fact that information about the intake of steroids are, generally, self reported and it is hardly possible to assess the exact dosage. AAS are often used in combination with other dugs or substances, so it is difficult to separate their toxic effects from those caused by the other drugs abused. Hence experimental studies conducted on animal models are mandatory to investigate the mechanisms underlying to AAS toxicity and the organ alterations due to these substances. Finally, clinicians should be aware of the complex and varied pattern of toxicity so as to be able to perform correct diagnoses and treatments.

    The introduction of biologics has revolutionized the treatment of moderate to severe plaque psoriasis. Due to the continuous expansion of biological therapies for psoriasis, it is particularly important to acknowledge efficacy and safety of the compounds not only in clinical trials but also in long-term registry-based observational studies. Typical side effects and significant risks of antipsoriatic biologic therapies considering psoriatic control groups are presented. A selective literature search was conducted in PubMed and long-term safety studies of the psoriasis registries PsoBest, PSOLAR and BADBIR were evaluated. To assess the long-term safety of biologics, the evaluation of the course of large patient cohorts in long-term registries is of particular medical importance. Newer biologic drugs seem to exhibit a better safety profile than older ones.

    Patients with functional gastrointestinal disorders treated with tricyclic antidepressants sometimes report nongastrointestinal symptoms; it is unclear whether these are drug side effects or reflect a behavioral tendency to report symptoms. We evaluated whether symptoms reported before treatment with a tricyclic antidepressant (desipramine) increased in number or worsened in severity after 2 weeks of treatment and assessed the baseline factors that predispose patients to report symptoms. Female patients in a multicenter National Institutes of Health trial for functional bowel disorders completed a 15-item symptom questionnaire at baseline (before randomization), 2 weeks after they were given desipramine (n = 81) or placebo (n = 40), and at study completion (12 weeks). Patients were asked about the severity and frequency of 15 symptoms. Results were analyzed from 57 patients given desipramine who completed the questionnaires. Symptoms reported as side effects to have occurred more frequently and also worsened at week 2 in the group given desipramine included dizziness, dry mouth/thirstiness, lightheadedness, jittery feelings/tremors, and flushing. Symptoms that did not change in severity or showed improvement at week 2 in the group given desipramine included morning tiredness, nausea, blurred vision, headaches, appetite reduction, and trouble sleeping. Psychologic distress but not desipramine blood level correlated with symptom reporting. Most symptoms often attributed to side effects of desipramine were present before treatment; only a few, related to anticholinergic effects, worsened 2 weeks after treatment, suggesting that most so-called side effects were not associated specifically with desipramine use. Such symptoms might instead be associated with psychologic distress.

    1985-03-01

    Side effects that have occurred in over 250 endobronchial laser treatments are reported. The laser has been used in severe tracheal and in bronchial obstructions. In two cases significant bleeding had to be treated with tamponade. In one patient an emphysema of the mediastinum developed, in 2 further patients a small pneumothorax. Perforation of the airway was not detected and no special treatment was necessary. Three patients with life-threatening tracheal stenoses and one patient with severe stenosis of both the mainstem bronchi due to metastasis in the bifurcation lymph node had a large defect in the tracheal or bronchial wall with a deep necrosis five to twelve weeks after laser treatment; all these patients had extensive radiotherapy in addition. One patient died due to severe respiratory insufficiency, probably caused by smoke intoxication. After the laser treatment, rubber-like fibrin-rich plaques may develop, which can lead to life-threatening obstructions of the airway. It is recommended that laser bronchoscopy should be performed with the rigid bronchoscope. After treatment of tracheal lesion an endoscopic check must be performed within 24 hours. The combination of laser treatment and radiotherapy seems to involve a certain risk of large defects in the bronchial wall due to necrosis of the tumor.

    Heat shock protein 10 (Hsp10) in eukaryotes, originally identified as a mitochondrial chaperone, now is also known to be present in cytosol, cell surface, extracellular space and peripheral blood. Functionally besides participating in mitochondrial protein folding in association with Hsp60, Hsp10 appears to be related to pregnancy, cancer and autoimmune inhibition. Hsp10 can be released to peripheral blood at very early time point of pregnancy and given another name called early pregnancy factor (EPF), which seems to play a critical role in developing a pregnant niche. In malignant disorders, Hsp10 is usually abnormally expressed in the cytosol of malignant cells and further released to extracellular space, resulting in tumor-promoting effect from various aspects. Furthermore, distinct from other heat shock protein members, whose soluble form is recognized as danger signal by immune cells and triggers immune responses, Hsp10 after release, however, is designed to be an inhibitory signal by limiting immune response. This review discusses how Hsp10 participates in various physiological and pathological processes from basic protein molecule folding to pregnancy, cancer and autoimmune diseases, and emphasizes how important the location is for the function exertion of a molecule.

    The study was conducted to compare the side effects in myelography of the two non-ionic water-soluble contrast medias, lopamidol (Niopam) and Metrizamide (Amipaque). A total of 111 patients were examined, 64 with lopamidol and 47 with Metrizamide. Side effects consisted of headache, nausea, vomiting, dizziness, urinary difficulty, muscular pain, seizure, neurobehavioral disturbance, neurological sign change, vital sign change and etc. The common side effects were headache, nausea, vomiting and dizziness in order of frequency. Most of the side effects were subsided within 24 hours following myelography. lopamidol myelography caused fewer and milder side effects than Metrizamide study. The side effects were more commonly observed in cervical, thoracic or total myelography than in lumbar myelography with either lopamidol or Metrizamide. There was no significant correlation between incidence of the side effects and premedication with phenobarbital or valium injection before myelography and CSF sampling during the procedure.

    Full Text Available Retinoids are compounds chemically related to vitamin A, which are frequently used in dermatological practice (1. They are characterized by numerous mechanisms of action leading to normalization of keratinocyte proliferation and maturation. They have anti-seborrhoeic, immunomodulatory and anti-inflammatory effects (1, 2. A number of side effects to retinoid treatment have been recorded; one group of such side effects relates to eyes and vision. Dry eye syndrome and blepharoconjunctivitis are the most common side effects, appearing in 20-50 % of patients treated with retinoids. They often contribute to the occurrence of other side-effects such as eye discomfort and contact lens intolerance. Due to the widespread use in clinical practice, the adverse effects, including ocular side effects, should be studied. To confirm the variety of adverse effects of retinoids, several case reports of rare side-effects are presented.

    Leukotriene receptor antagonists (LTRAs) are drugs which have been widely used more than ten years. As the use of LTRAs increases, our knowledge with respect to their side effects increases as well. The objective of our study was to evaluat the observed side effects of LTRAs used in patients with astma. 1024 patients treated only with LTRAs owing to asthma or early wheezing were included in the study for a five-year period. The observed side effects of LTRAs in these patients were retrospectively investigated. The side effects were divided into two parts as psychiatric and non-psychiatric. Among the 1024 cases included in the study, 67.5% of the patients out of 41 with side effects were male, 32.5% were female and the average age was 6.5 years. The rate of patients with asthma was 63.41% and 36.58% of the patients had early wheezing. It was determined that sex, age and diagnosis (early wheezing or asthma) of the patients were ineffective in the emergence of side effects. The average period for the emergence of side effects was the first month. It was observed that hyperactivity was the most frequently observed psychiatric side effect and that abdominal pain was the non-psychiatric side effect. The side effects of LTRAs were common in children. Therefore, patients must be informed at the beginning of the treatment and they must be evaluated at certain intervals.

    Body positioning exerts a strong effect on pulmonary function, but its effect on other components of the oxygen transport pathway are less well understood, especially the effects of side-lying positions. This study investigated the interrelationships between side-lying positions and indexes of lung function such as spirometry, alveolar diffusing capacity, and inhomogeneity of ventilation in older individuals. Nineteen nonsmoking subjects (mean age=62.8 years, SD=6.8, range=50-74) with no history of cardiac or pulmonary disease were tested over 2 sessions. The test positions were sitting and left side lying in one session and sitting and right side lying in the other session. In each of the positions, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), single-breath pulmonary diffusing capacity (DLCO/VA), and the slope of phase III (DN2%/L) of the single-breath nitrogen washout test to determine inhomogeneity of ventilation were measured. Compared with measurements obtained in the sitting position, FVC and FEV1 were decreased equally in the side-lying positions, but no change was observed in DLCO/VA or DN2%/L. Side-lying positions resulted in decreases in FVC and FEV1, which is consistent with the well-documented effects of the supine position. These findings further support the need for prescriptive rather than routine body positioning of patients with risks of cardiopulmonary compromise and the need to use upright positions in which lung volumes and capacities are maximized.

  11. Are peripheral opioid antagonists the solution to opioid side effects?

    LENUS (Irish Health Repository)

    Bates, John J

    2012-02-03

    Opioid medication is the mainstay of therapy for severe acute and chronic pain. Unfortunately, the side effects of these medications can affect patient comfort and safety, thus limiting their proven therapeutic potential. Whereas the main analgesic effects of opioids are centrally mediated, many of the common side effects are mediated via peripheral receptors. Novel peripheral opioid antagonists have been recently introduced that can block the peripheral actions of opioids without affecting centrally mediated analgesia. We review the clinical and experimental evidence of their efficacy in ameliorating opioid side effects and consider what further information might be useful in defining their role. IMPLICATIONS: The major analgesic effects of opioid medication are mediated within the brain and spinal cord. Many of the side effects of opioids are caused by activation of receptors outside these areas. Recently developed peripherally restricted opioid antagonists have the ability to block many opioid side effects without affecting analgesia.

    The paper addresses the safety of febuxostat and summarizes reports on side effects and interactions of febuxostat published by the cut-off date (last day of literature search) of 20 March 2018. Publications on side effects and the interactions of febuxostat were considered. Information concerning the occurrence of side effects and interactions in association with the treatment with febuxostat was collected and summarized in the review. The incidence of severe side effects was much less frequent than mild side effects (1.2⁻3.8% to 20.1⁻38.7%). The rate and range of febuxostat side effects are low at doses of up to 120 mg and only increase with a daily dose of over 120 mg. The publications reveal no age-dependent increase in side effects for febuxostat. In patients with impaired renal function, no increase in adverse events is described with a dose of up to 120 mg of febuxostat per day. Patients with impaired liver function had no elevated risk for severe side effects. A known allopurinol intolerance increases the risk of skin reactions during treatment with febuxostat by a factor of 3.6. No correlation between treatment with febuxostat and agranulocytosis has been confirmed. Possible interactions with very few medications (principally azathioprine) are known for febuxostat. Febuxostat is well tolerated and a modern and safe alternative to allopurinol therapy.

    Zolpidem is one of the newer medications developed for the treatment of insomnia. It is an imidazopyridine agent that is an alternative to the typical sedative-hypnotic agents. Zolpidem use is gaining favor because of its efficacy and its side effect profile, which is milder and less problematic than that of the benzodiazepines and barbiturates used to treat insomnia. Still, side effects are not uncommon with zolpidem use. We report a series of cases in which the patients developed delirium, nightmares and hallucinations during treatment with zolpidem. We will review its pharmacology, discuss previous reports of central nervous system side effects, examine the impact of drug interactions with concurrent use of antidepressants, examine gender differences in susceptibility to side effects, and explore the significance of protein binding in producing side effects.

  18. Side Flow Effect on Surface Generation in Nano Cutting.

    Science.gov (United States)

    Xu, Feifei; Fang, Fengzhou; Zhang, Xiaodong

    2017-12-01

    The side flow of material in nano cutting is one of the most important factors that deteriorate the machined surface quality. The effects of the crystallographic orientation, feed, and the cutting tool geometry, including tool edge radius, rake angle and inclination angle, on the side flow are investigated employing molecular dynamics simulation. The results show that the stagnation region is formed in front of tool edge and it is characterized by the stagnation radius R s and stagnation height h s . The side flow is formed because the material at or under the stagnation region is extruded by the tool edge to flow to the side of the tool edge. Higher stagnation height would increase the size of the side flow. The anisotropic nature of the material which partly determines the stagnation region also influences the side flow due to the different deformation mechanism under the action of the tool edge. At different cutting directions, the size of the side flow has a great difference which would finally affect the machined surface quality. The cutting directions of {100} , {110} , and {110}  are beneficial to obtain a better surface quality with small side flow. Besides that, the side flow could be suppressed by reducing the feed and optimizing the cutting tool geometry. Cutting tool with small edge radius, large positive rake angle, and inclination angle would decrease the side flow and consequently improve the machined surface quality.

  19. In vivo assessment of antiretroviral therapy-associated side effects

    2014-07-01

    Full Text Available Antiretroviral therapy has been associated with side effects, either from the drug itself or in conjunction with the effects of human immunodeficiency virus infection. Here, we evaluated the side effects of the protease inhibitor (PI indinavir in hamsters consuming a normal or high-fat diet. Indinavir treatment increased the hamster death rate and resulted in an increase in triglyceride, cholesterol and glucose serum levels and a reduction in anti-oxLDL auto-antibodies. The treatment led to histopathological alterations of the kidney and the heart. These results suggest that hamsters are an interesting model for the study of the side effects of antiretroviral drugs, such as PIs.

Little is known, however, about sildenafil’s side effects in this population.Methods: Single institution, longitudinal survey-based study performed in an outpatient pediatric cardiology clinic. Pediatric patients on sildenafil (alone or in combination with other PH therapies completed questionnaires regarding frequency of vascular, gastrointestinal, neurologic and hematologic side effects. Results: Between January 2011 and May 2014, 66 pediatric patients with PH on sildenafil filled out 214 surveys, 32 patients (96 surveys on monotherapy, and 43 patients (118 surveys on sildenafil plus an endothelin receptor antagonist (bosentan or ambrisentan and/or a prostacyclin (epoprostenol or treprostinil. Overall, 30% of respondents identified at least one side effect. For all patients on sildenafil, incidence of side effects by system was 37% gastrointestinal, 35% vascular and 22% neurologic. For patients on sildenafil monotherapy, incidence of side effects by system was 24% gastrointestinal, 21% vascular and 18% neurologic compared to patients on combination therapy who reported an incidence of 48% gastrointestinal, 45% vascular and 25% neurologic.Conclusion: Incidence of vascular, gastrointestinal and neurologic side effect in pediatric patients on sildenafil therapy for pulmonary arterial hypertension was 30%. Side effects were more common in patients on combination therapy with an endothelin receptor antagonist and/or prostacyclin than in patients on sildenafil monotherapy.

    Multiple sclerosis (MS) is an immune-mediated and neurodegenerative disease with an unpredictable outcome. Immune-modulatory treatment aims at decreasing long-term disability. With the increasing number of treatment options, it is essential to fully digest the possible side effects of the available therapeutics and to monitor patients is essential. Areas covered: All approved disease-modifying drugs (DMD) for MS are discussed in this review. Mode of action, adverse effects, reported risks for infections and malignancies, and pregnancy related issues are discussed in the review. The authors also provide suggestions for monitoring therapy. For all approved DMDs the pivotal studies have been included for possible side effects, as well as reports by health authorities. For this manuscript, PubMed was checked for reports on side effects for various drugs. Expert opinion: Treatment options in MS are manifold, each carrying different risks. The safety-risk profile for approved agents is favorable. Knowing and monitoring these possible side effects is essential to minimize risks associated with treatment. Presently, the long-term experience for some of these therapies is missing and this must be addressed.

    Anti-programmed cell death receptor-1 (PD-1) antibodies represent an effective treatment option for metastatic melanoma as well as for other cancer entities. They act via blockade of the PD-1 receptor, an inhibitor of the T-cell effector mechanisms that limit immune responses against tumours. As reported for ipilimumab, the anti-PD-1 antibodies pembrolizumab and nivolumab can induce immune-related adverse events (irAEs). These side-effects affect skin, gastrointestinal tract, liver, endocrine system and other organ systems. Since life-threatening and fatal irAEs have been reported, adequate diagnosis and management are essential. In total, 496 patients with metastatic melanoma from 15 skin cancer centers were treated with pembrolizumab or nivolumab; 242 side-effects were described in 138 patients. In 116 of the 138 patients, side-effects affected the skin, gastrointestinal tract, liver, endocrine, and renal system. Rare side-effects included diabetes mellitus, lichen planus, and pancreas insufficiency due to pancreatitis. Anti-PD1 antibodies can induce a plethora of irAEs. The knowledge of them will allow prompt diagnosis and improve the management resulting in decreased morbidity. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Capturing service users' perspectives can highlight additional and different concerns to those of clinicians, but there are no up to date, self-report psychometrically sound measures of side effects of antipsychotic medications. Aim To develop a psychometrically sound measure to identify antipsychotic side effects important to service users, the Maudsley Side Effects (MSE) measure. An initial item bank was subjected to a Delphi exercise (n = 9) with psychiatrists and pharmacists, followed by service user focus groups and expert panels (n = 15) to determine item relevance and language. Feasibility and comprehensive psychometric properties were established in two samples (N43 and N50). We investigated whether we could predict the three most important side effects for individuals from their frequency, severity and life impact. MSE is a 53-item measure with good reliability and validity. Poorer mental and physical health, but not psychotic symptoms, was related to side-effect burden. Seventy-nine percent of items were chosen as one of the three most important effects. Severity, impact and distress only predicted 'putting on weight' which was more distressing, more severe and had more life impact in those for whom it was most important. MSE is a self-report questionnaire that identifies reliably the side-effect burden as experienced by patients. Identifying key side effects important to patients can act as a starting point for joint decision making on the type and the dose of medication.

  5. Membrane Transporters as Mediators of Cisplatin Effects and Side Effects

    Full Text Available Transporters are important mediators of specific cellular uptake and thus, not only for effects, but also for side effects, metabolism, and excretion of many drugs such as cisplatin. Cisplatin is a potent cytostatic drug, whose use is limited by its severe acute and chronic nephro-, oto-, and peripheral neurotoxicity. For this reason, other platinum derivatives, such as carboplatin and oxaliplatin, with less toxicity but still with antitumoral action have been developed. Several transporters, which are expressed on the cell membranes, have been associated with cisplatin transport across the plasma membrane and across the cell: the copper transporter 1 (Ctr1, the copper transporter 2 (Ctr2, the P-type copper-transporting ATPases ATP7A and ATP7B, the organic cation transporter 2 (OCT2, and the multidrug extrusion transporter 1 (MATE1. Some of these transporters are also able to accept other platinum derivatives as substrate. Since membrane transporters display a specific tissue distribution, they can be important molecules that mediate the entry of platinum derivatives in target and also nontarget cells possibly mediating specific effects and side effects of the chemotherapeutic drug. This paper summarizes the literature on toxicities of cisplatin compared to that of carboplatin and oxaliplatin and the interaction of these platinum derivatives with membrane transporters.

    Full Text Available The activating/co-stimulatory receptor NKG2D (natural-killer group 2, member D is expressed on the surface of all human NK, NKT, CD8+ T and subsets of γδ+ T cells. The significance of NKG2D function in tumor immunity has been well demonstrated in experimental animal models. However, the role of human NKG2D ligands in regulating tumor immunity and cancer prognosis had been controversial in the literature. In this review, we summarize the latest advancement, discuss the controversies, and present evidence that membrane-bound and soluble NKG2D ligands oppositely regulate tumor immunity. We also discuss new perspectives of targeting NKG2D ligands for cancer immunotherapy.

    2014-12-01

    Full Text Available [english] Phytoestrogens are present in certain edible plants being most abundant in soy; they are structurally and functionally analogous to the estrogens. Phytoestrogens have been applied for compensation of hormone deficiency in the menopause. At the same time, soy products are used in infant food and other foodstuffs. Furthermore, soy is applied as animal fodder, so that residual phytoestrogens and their active metabolites such as equol can remain in meat and influence the hormonal balance of the consumers. There have been only singular reports on modified gender-related behavior or feminization in humans in consequence of soy consumption. In animals, the intake of phytoestrogens was reported to impact fertility, sexual development and behavior. Feminizing effects in humans can be subtle and identifiable only statistically in large populations.

    Both technological and social fixes are likely to bring with them deterimental and unforeseen side effects. Although the perceived side effects of nuclear energy can undoubtedly be ameliorated by improved technology, a permanent institutional infrastructure will probably also be required. It is pointed out that confinement of nuclear energy to relatively few large sites rather than many small sites may be a first step toward creating this permanent institutional infrastructure.

    Allergen-specific immunotherapy is the only causal form of therapy for IgE-mediated allergic diseases. Subcutaneous immunotherapy (SCIT) is considered safe and well tolerated in adults, yet there is less evidence of safety in the pediatric population. A non-interventional prospective observing longitudinal study was carried out to determine the incidence of local and systemic side effects by SCIT, routinely performed in pediatric patients. A total of 581 pediatric patients were observed in 18 study centers between March 2012 and October 2014, recording 8640 treatments and 10 015 injections. A total of 54.6% of the patients experienced immediate local side effects at least once; delayed local side effects were seen in 56.1%. Immediate systemic adverse reactions occurred in 2.2% of patients; 7.4% experienced delayed systemic side effects. However, severe systemic side effects (grade III in the classification of Ring and Messmer) were seen in 0.03% of all treatments, all appearing within 30 minutes after the injections. No grade IV reactions were observed. In addition, many potential risk factors were investigated, yet only a few were found to be associated with the occurrence of side effects. Subcutaneous immunotherapy is a safe form of therapy in pediatric patients, with similar rates of local side effects compared to adult patients and low rates of severe systemic side effects. However, local and systemic reactions occurring later than 30 minutes after injection were observed more often than expected, which makes it essential to be attentive on behalf of pediatricians, patients, and parents. © 2017 EAACI and John Wiley and Sons A/S.

    1987-01-01

    A prospective, controlled study was performed to compare side effect incidences after lumbar iohexol myelography (n=97) and diagnostic lumbar puncture (n=85). No significant side effect incidence differences (iohexol vs. controls) were found regarding number of patients with any side effect (63 vs. 73%), headache (44 vs. 54%), nausea, dizziness, visual, auditory, or psychic symptoms. Early-onset headache occurred significantly more often in the iohexol group (16 vs 5%), while postural headache occurred most frequently after lumbar puncture (25 vs. 41%). These results suggest that apart from the slight early-onset headache, most side effets after lumbar iohexol myelography are related to the puncture per se, not to the contrast agent. (orig.)

    Side effects in the therapy of malignant melanoma are primarily of importance for radiologists in advanced tumor stages. The available treatment options and their respective side effect profiles have undergone a profound change in recent years after the introduction of modern oncological therapies (e.g. immunotherapy and targeted therapy) with an increasing focus on individual tumor biology and differ significantly from those of classical chemotherapy. The immunotherapeutic agents, in particular ipilimumab, take on a special position because of their specific immune-mediated mechanisms of action and the associated side effects, so-called immune-related adverse events (irAE). The majority of the treatment effects are manifested on the skin (> 50 %) and are generally not detectable by diagnostic radiology. Only a comparatively small proportion of treatment side effects is detectable with diagnostic imaging (15-20 %) but as in the example of therapy-induced colitis with ipilimumab, may be rapidly fatal. In addition to colitis (10-20 %) further therapy side effects apparent in diagnostic imaging are hypophysitis (1.8-17 %), thyroiditis (0.8 %), myositis (1.7 %), fasciitis and sarcoid-like lymph node alterations (6.8 %). To detect radiologically detectable side effects early on and to delineate them especially from tumor progression and (opportunistic) infections, detailed knowledge of the therapeutic methods for melanoma, the mechanisms of action and in particular the sometimes very specific side effects is imperative for radiologists. (orig.) [German] Nebenwirkungen der Therapie des malignen Melanoms sind fuer den Radiologen primaer in fortgeschrittenen Tumorstadien von Bedeutung.

    Dipyridamole is an agent that may be used to noninvasively evaluate coronary artery disease. The effect of dipyridamole infusion its generally related to its induced peripheral vasodilatory effect. In normal person, heart rate is generally increased slightly while blood pressure decrease, but the achieved double product and related myocardial oxygen consumption have no significant change. The purpose of this study is to examine the effect and side effect of dipyridamole, and to compare different response to dipyridamole among the patients. We evaluated 847 patients who underwent dipyridamole stress myocardial SPECT. 93.6% of them had induced hypotension 0.9% showed no change of blood pressure, 5.5% had increased blood pressure 8.3% had no change of pulse rate more than 10% of basal pulse rate. Among diabetes, 16.9% was not change of pulse rate, 6.7% in non-diabetes. There was no significant correlation between age and rate pressure product rest(RPPr), in patients without perfusion defects on SPECT(y=7.1x+48.4r=0.13 p>0.01). As increasing age, RPPs/RPPr was declined(y=-11.6x+68.9 r=0.17 p<0.01), similar results were obtained in patients with perfusion defect. The size of perfusion defect on myocardial SPECT have no correlation between RPPr and RPPs/RPPr. The side effects of dipyridamole included chest pain and chest tightness, headache, abdominal pain, dizziness, nausea, and dyspnea. As increasing age, dipyridamole-induced cardiac work at rest was increased, cardiac response to dipyridamole was decreased.

    Full Text Available Phototherapy (PUVA ve UVB is a widely used and effective treatment method for a variety of dermatological diseases. Adverse effects associated with phototherapy can be classified as acute and chronic side effects. Acute side effects are mostly related with UV doses and drug intolerance, and include itching, nausea, erythema, edema and phototoxic reactions that sometimes blister formation is seen. Acute side effects are usually moderate and transient. Chronic side effects of phototherapy are early aging of skin, pigmentary changes and increased risk of skin carcinogenesis. The major concern is development of skin cancer. This risk is especially related to long-term exposure and high cumulative doses of PUVA, increase in time and is persistent. Therefore, risk/advantage ratio of phototherapy should be carefully evaluated in each patient, and treatment protocols with minimal UV exposure should be chosen according to the phototherapy guides. Follow-up of the patients for long terms is important in prevention or in reduction of this risk by detecting and treating any premalignant or malignant lesion early. In this article, acute and chronic side effects of phototherapy are reviewed with recent literature findings.

    Migraine is a neurovascular disorder. Current acute specific antimigraine pharmacotherapies target trigeminovascular 5-HT 1B/1D , 5-HT 1F and CGRP receptors but, unfortunately, they induce some cardiovascular and central side effects that lead to poor treatment adherence/compliance. Therefore, new antimigraine drugs are being explored. Areas covered: This review considers the adverse (or potential) side effects produced by current and prospective antimigraine drugs, including medication overuse headache (MOH) produced by ergots and triptans, the side effects observed in clinical trials for the new gepants and CGRP antibodies, and a section discussing the potential effects resulting from disruption of the cardiovascular CGRPergic neurotransmission. Expert opinion: The last decades have witnessed remarkable developments in antimigraine therapy, which includes acute (e.g. triptans) and prophylactic (e.g. β-adrenoceptor blockers) antimigraine drugs. Indeed, the triptans represent a considerable advance, but their side effects (including nausea, dizziness and coronary vasoconstriction) preclude some patients from using triptans. This has led to the development of the ditans (5-HT 1F receptor agonists), the gepants (CGRP receptor antagonists) and the monoclonal antibodies against CGRP or its receptor. The latter drugs represent a new hope in the antimigraine armamentarium, but as CGRP plays a role in cardiovascular homeostasis, the potential for adverse cardiovascular side effects remains latent.

    The side effects of primary percutaneous radiotherapy in 100 patients with prostatic cancer were evaluated and classified into different degrees of gravity. It was shown that especially chronic side effects are benign in most of all cases. Severe - but not vitally dangerous - complications in bladder and intestine are rare (3%); their percentage corresponds roughly to the average mortality rate of surgical intervention (radical prostatectomy). Contrary to operation, troubles of the sexual function appear only in one third of the patients. Taking into consideration the similar therapeutic results of intervention and radiotherapy, radiotherapy is more favorable with respect to side effects. This essential aspects should be considered when making a decision whether to apply a surgical or radiotherapeutic treatment. (orig.) [de

    To explore the actions cancer patients reported they would take in response to a range of common side effects of chemotherapy and whether these were considered appropriate based on current guidelines and evidence; and to explore the sociodemographic and cancer-related variables associated with patients selecting the appropriate action (immediate medical attention or reporting) for two potentially life-threatening side effects: fever, and unusual bleeding and bruising. Four hundred thirty-six medical oncology and haematology patients receiving chemotherapy completed two surveys to provide demographic, disease and treatment characteristics, and details on how they would respond if they experienced a range of specified side effects of chemotherapy (for example, nausea and vomiting, fatigue, and skin rash or nail changes). The proportion of patients reporting the appropriate action for each side effect was calculated. Multiple logistic regressions examined the patient demographic and cancer characteristics associated with selecting the appropriate action (seeking immediate medical attention) for two potentially life-threatening side effects of chemotherapy: high fever of 38 °C or more, and unusual bleeding or bruising. Two thirds of patients indicated that they would seek immediate medical attention for high fever (67%), but only 41% would seek immediate attention for bleeding or bruising. Cancer type and time since diagnosis were significantly associated with patients indicating that they would seek immediate medical attention for high fever; while time since diagnosis was the only variable significantly associated with patients reporting that they would seek immediate medical attention for unusual bleeding or bruising. For chronic side effects, like skin rash or nail changes, and tingling or numbness, which usually do not require urgent reporting, only between 12 and 16% would report them immediately. A significant proportion of patients reported that they would

    Full Text Available Disharmonious of dental arrangement can possibly create problems for the patient, such as the masticatory function, esthetical, psychosocial, and also the increased risk of trauma and periodontal disease. These are reasons for a patient to seek orthodontic treatment. The aim of this study was to know the patient’s knowledge about the side effects possibility that they receive during orthodontic treatment. The side effects include pain experience during orthodontic treatment, the possibility of soft tissue damage, email demineralization, loss of tooth vitality, periodontal problem, root resorption, temporomandibular joint disorders, and relapse. A cross-sectional study was conducted in patients who registered at Orthodontic Department, Faculty of Dentistry, Universitas Indonesia on March-June 2009. The participants of this study were 100 patients, consist of 86 women and 14 men respectively. Twenty-seven questions about the side-effects of orthodontic treatment were used to obtain the patient’s knowledge and the result was categorized into 3 groups, good, average and poor. The result of the study showed that patient’s knowledge about the side effect of pain experience during orthodontic treatment was average and the patient’s knowledge about the possibility of soft tissue damage due to orthodontic treatment was good. However, the patient’s knowledge about the possibility of email demineralization, loss of tooth vitality, periodontal problem, root resorption, temporomandibular joint disorders and relapse due to orthodontic treatment was low.

    2011-09-01

    Cannabidiol (CBD), a major nonpsychotropic constituent of Cannabis, has multiple pharmacological actions, including anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties. However, little is known about its safety and side effect profile in animals and humans. This review describes in vivo and in vitro reports of CBD administration across a wide range of concentrations, based on reports retrieved from Web of Science, Scielo and Medline. The keywords searched were "cannabinoids", "cannabidiol" and "side effects". Several studies suggest that CBD is non-toxic in non-transformed cells and does not induce changes on food intake, does not induce catalepsy, does not affect physiological parameters (heart rate, blood pressure and body temperature), does not affect gastrointestinal transit and does not alter psychomotor or psychological functions. Also, chronic use and high doses up to 1,500 mg/day of CBD are reportedly well tolerated in humans. Conversely, some studies reported that this cannabinoid can induce some side effects, including inhibition of hepatic drug metabolism, alterations of in vitro cell viability, decreased fertilization capacity, and decreased activities of p-glycoprotein and other drug transporters. Based on recent advances in cannabinoid administration in humans, controlled CBD may be safe in humans and animals. However, further studies are needed to clarify these reported in vitro and in vivo side effects.

  11. The Economic Side Effects of Dangerous Drug Announcements.

    OpenAIRE

    Dranove, David; Olsen, Chris

    1994-01-01

    Immediately prior to the passage of the 1962 Food and Drug Administration Amendments, there were a number of drugs recalled from markets worldwide. Announcements about the dangerous side effects of these drugs were associated with lower-share prices for their manufacturers and the industry as a whole. We perform several analyses to sort out alternative explanations for the observed declines. We find that dangerous drug announcements had no effect on the sales of other drugs and didn't affect ...

    The essay gives a brief survey of possible side effects occurring in irradiating patients with carinomas of the breast. Special attention is paid to difficulties concerning differential diagnosis and occurring in differentiating radiation reactions from secondary blastomas in the skeleton system. The problems concerning lymphatic oedema in the arm, and changes in the lungs and the effects of radiotherapy on the haematopoictic system are dealt with.

    2016-01-01

    A randomized clinical trial of 100 children (52 boys, 48 girls) ages 2 months to 7 years was conducted to evaluate the effect of vibration therapy without cold analgesia on pain. A convenience sample was recruited at two sites: a publicly funded, free immunization clinic and a private group pediatric practice. Participants were randomly assigned to receive vibration therapy via a specialized vibrating device or standard care. All children regardless of intervention group were allowed to be distracted and soothed by the parent. Pain was evaluated using the FLACC score, which two nurses assessed at three points in time: prior to, during, and after the injection(s). Data were analyzed using a two-independent samples-paired t-test. Results show that vibration therapy had no effect on pain scores in the younger age groups studied (2 months ≤ 1 year, > 1 year ≤ 4 years). In the oldest age group (> 4 to 7 years of age), a heightened pain reading was found in the period from preinjection to post-injection periods (p = 0.045). These results indicate that the addition of vibration therapy (without cold analgesia) to standard soothing techniques is no more effective in reducing immunization pain than standard soothing techniques alone, and thus, is not indicated for use with immunization pain. Recommendations include further evaluation of interventions.

    Novel painkillers are urgently needed. The activation of opioid receptors in peripheral inflamed tissue can reduce pain without central adverse effects such as sedation, apnoea, or addiction. Here, we use an unprecedented strategy and report the synthesis and analgesic efficacy of the standard opioid morphine covalently attached to hyperbranched polyglycerol (PG-M) by a cleavable linker. With its high-molecular weight and hydrophilicity, this conjugate is designed to selectively release morphine in injured tissue and to prevent blood-brain barrier permeation. In contrast to conventional morphine, intravenous PG-M exclusively activated peripheral opioid receptors to produce analgesia in inflamed rat paws without major side effects such as sedation or constipation. Concentrations of morphine in the brain, blood, paw tissue, and in vitro confirmed the selective release of morphine in the inflamed milieu. Thus, PG-M may serve as prototype of a peripherally restricted opioid formulation designed to forego central and intestinal side effects.

    2013-01-01

    Guidelines from throughout the world recommend intranasal corticosteroids (INSs) as first-line treatment for most patients with moderate to severe allergic rhinitis. In general, limited comparative studies between different INSs have not indicated that one particular steroid moiety is more effective than another in controlling symptoms of allergic rhinitis. However, there are numerous formulations available with different ingredients that may influence a patient's adherence to treatment. This article looks at topical features with these agents, specifically, formulations, vehicles (aqueous vs aerosol), and side effects such as epistaxis and nasal septal perforation. Topical side effects are minimal with INSs with the exception of epistaxis. There are major differences in formulations, volumes, and vehicles between INSs, which could affect adherence. Physicians need to be aware of the different INS attributes to try to match patients' preferences in order to achieve better adherence and improve outcomes in sufferers of allergic rhinitis.

  16. Cutaneous side-effects during therapy of melanoma by vemurafenib

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Introduction. Vemurafenib is a selective inhibitor of serine-threonine kinase BRAF used in the treatment of advanced melanoma with BRAF mutation. Effectiveness of this drug was confirmed in a large clinical trial, which led to the increase of its usage. During treatment with vemurafenib, particular attention should be paid to the numerous side effects, including those concerning the skin. Vemurafenib is highly toxic to the skin. Skin lesions occurring during the treatment of melanoma with this medicament can be divided into: early (observed 3 to 6 weeks after beginning treatment, late (observed 6 weeks after beginning treatment and hypersensitivity reactions to vemurafenib. Objective. Presentation of vemurafenib toxic effects on the skin and side effects that can be caused by this drug. Case report. We present a 58-year-old woman with metastatic melanoma who was treated with vemurafenib. During the course of therapy, numerous adverse reactions, including inflammatory tumors, emergence of a number of melanocytic naevi, skin horns, alopecia, hyperkeratosis of the palms and soles, and palmar erythrodysesthesia were observed. She was treated with anti-inflammatory drugs, an antibiotic, circulation-improving preparations and local moisturizing and keratolytic treatment. The patient remains under the care of oncologists and dermatologists. Conclusions. The new generation anti-cancer drugs bring hope for a cure or prolongation of life, but can also significantly reduce the quality of life by inducing both general and local adverse side effects. Oncological patients should also be taken care of by dermatologists.

  17. Ketamine for Pain Management-Side Effects & Potential Adverse Events.

    Allen, Cheryl A; Ivester, Julius R

    2017-12-01

    An old anesthetic agent, ketamine is finding new use in lower doses for analgesic purposes. There are concerns stemming from its potential side effects-specifically psychomimetic effects. These side effects are directly related to dose amount. The doses used for analgesic purposes are much lower than those used for anesthesia purposes. A literature review was performed to ascertain potential side effects and/or adverse events when using ketamine for analgesia purposes. The search included CINAHL, PubMed, and Ovid using the search terms "ketamine," "ketamine infusion," "pain," "adverse events," "practice guideline," and "randomized controlled trial." Searches were limited to full-text, peer-reviewed articles and systematic reviews. Initially 1,068 articles were retrieved. The search was then narrowed by using the Boolean connector AND with various search term combinations. After adjusting for duplication, article titles and abstracts were reviewed, leaving 25 articles for an in-depth analysis. Specific exclusion criteria were then applied. The literature supports the use of ketamine for analgesic purposes, and ketamine offers a nonopioid option for the management of some pain conditions. Because ketamine is still classified as an anesthetic agent, health care institutions should develop their own set of policies and protocols for the administration of ketamine. By using forethought and understanding of the properties of ketamine, appropriate care may be planned to mitigate potential side effects and adverse events so that patients are appropriately cared for and their pain effectively managed.

    Langmann, G.; Faulborn, J.; Poier, E.

    1994-01-01

    When effectiveness is evaluated in brachytherapy with Ruthenium 106 special emphasis has to be put on tumor destruction and late side effects responsible for the definite functional results. We evaluated the late side effects of 22 uveal melanomas, which had been treated with 106 Ruthenium plaques. The tumor prominences ranged from 3 to 10 mm, the diameter from 4 to 9 disc diameters. In 4 patients the tumor involved the posterior pole, 14 melanomas were located in the midperiphery of the fundus, 4 tumors were ciliary body melanomas. The total radiation dose of the apex ranged from 100 to 240 Gy with a corresponding dose to the sclera between 540 to 1000 Gy. Because of the short half life of the plaque we have been using different dose rates (1.6-11 Gy/h). In 17/22 eyes adequate regression could be achieved by Ruthenium therapy alone. In one case additional laser treatment of the macular part of the melanoma had to be performed, Gamma Knife therapy was necessary in another melanoma with 10 mm tumor prominence. 3 recurrences led to enucleation. The mean follow up was 4.8 years ranging from 1 to 7 years. In 2/22 patients opticopathy caused severe visual impairment, in another 2 patients radiation maculopathy and opticopathy was observed. 7/22 developed vasculopathy with neovascularization treated by photocoagulation. In one case of focal radiation maculopathy laser treatment could prevent further visual impairment. The following factors are responsible for a higher incidence of late side effects: 1. High dose rate of the plaques in combination with a high radiation dose to the sclera 2. Location of the tumor within a minimum distance of 2 disc diameters to the optic nerve or macula 3. Tumor location at the ciliary body Laser treatment in case of neovascularization and focal radiation maculopathy is the only effective treatment with regard to late side effects. Ischemic maculopathy and radiation opticopathy are responsible for late visual impairment. (authors)

  19. Effect of Different Adjuvants on Protection and Side-Effects Induced by Helicobacter suis Whole-Cell Lysate Vaccination.

    Full Text Available Helicobacter suis (H. suis is a widespread porcine gastric pathogen, which is also of zoonotic importance. The first goal of this study was to investigate the efficacy of several vaccine adjuvants (CpG-DNA, Curdlan, Freund's Complete and Incomplete, Cholera toxin, administered either subcutaneously or intranasally along with H. suis whole-cell lysate, to protect against subsequent H. suis challenge in a BALB/c infection model. Subcutaneous immunization with Freund's complete (FC/lysate and intranasal immunization with Cholera toxin (CT/lysate were shown to be the best options for vaccination against H. suis, as determined by the amount of colonizing H. suis bacteria in the stomach, although adverse effects such as post-immunization gastritis/pseudo-pyloric metaplasia and increased mortality were observed, respectively. Therefore, we decided to test alternative strategies, including sublingual vaccine administration, to reduce the unwanted side-effects. A CCR4 antagonist that transiently inhibits the migration of regulatory T cells was also included as a new adjuvant in this second study. Results confirmed that immunization with CT (intranasally or sublingually is among the most effective vaccination protocols, but increased mortality was still observed. In the groups immunized subcutaneously with FC/lysate and CCR4 antagonist/lysate, a significant protection was observed. Compared to the FC/lysate immunized group, gastric pseudo-pyloric metaplasia was less severe or even absent in the CCR4 antagonist/lysate immunized group. In general, an inverse correlation was observed between IFN-γ, IL-4, IL-17, KC, MIP-2 and LIX mRNA expression and H. suis colonization density, whereas lower IL-10 expression levels were observed in partially protected animals.

    Chromium is a naturally occurring heavy metal found commonly in the environment in trivalent, Cr(III), and hexavalent, Cr(VI), forms. Cr(VI) compounds have been declared as a potent occupational carcinogen among workers in chrome plating, stainless steel, and pigment industries. The reduction of Cr(VI) to Cr(III) results in the formation of reactive intermediates that together with oxidative stress oxidative tissue damage and a cascade of cellular events including modulation of apoptosis regulatory gene p53, contribute to the cytotoxicity, genotoxicity and carcinogenicity of Cr(VI)-containing compounds. On the other hand, chromium is an essential nutrient required to promote the action of insulin in body tissues so that the body can use sugars, proteins and fats. Chromium is of significant importance in altering the immune response by immunostimulatory or immunosuppressive processes as shown by its effects on T and B lymphocytes, macrophages, cytokine production and the immune response that may induce hypersensitivity reactions. This review gives an overview of the effects of chromium on the immune system of the body. Copyright 2002 Federation of European Microbiological Societies

To facilitate the safety assessment of NMPs, we aimed to gain insight into toxic effects specific for NMPs by systematically analyzing the available toxicity data on approved NMPs in the European Union. In addition, by comparing five sets of products with the same active pharmaceutical ingredient (API in a conventional formulation versus a nanoformulation, we aimed to identify any side effects specific for the nano aspect of NMPs. The objective was to investigate whether specific toxicity could be related to certain structural types of NMPs and whether a nanoformulation of an API altered the nature of side effects of the product in humans compared to a conventional formulation. The survey of toxicity data did not reveal nanospecific toxicity that could be related to certain types of structures of NMPs, other than those reported previously in relation to accumulation of iron nanoparticles (NPs. However, given the limited data for some of the product groups or toxicological end points in the analysis, conclusions with regard to (a lack of potential nanomedicine-specific effects need to be

    This randomized crossover out-patient study was designed to compare the antihypertensive effects of atenolol and pindolol. After a wash-out period of two weeks in pretreated cases, 107 patients with essential hypertension were given either atenolol 100 mg once-daily or pindolol 20 mg slow release (SR) once-daily. Both atenolol and pindolol lowered blood pressure over the 24 week period. The diastolic blood pressure reduction was significantly greater (p less than 0.01) with atenolol than with pindolol. Before beta-blocker therapy, many patients had already experienced side-effects such as fatigue, sleep disturbances and dreams. This probably relates to the high sensitivity of the analogue scale used to assess side-effects, and to the high incidence of such symptoms in untreated patients. As the study progressed there was a reduction in the frequency of fatigue (p less than 0.03) and dreams (p less than 0.05) in both groups, whereas sleep disturbances significantly increased under pindolol (p less than 0.05) but decreased under atenolol (p less than 0.05). The only important side-effect difference between the two beta-blockers was the higher incidence of sleep disturbances with pindolol which may be due to the higher lipophilicity of this beta-blocker.

    Targets for drugs have so far been predicted on the basis of molecular or cellular features, for example, by exploiting similarity in chemical structure or in activity across cell lines. We used phenotypic side-effect similarities to infer whether two drugs share a target. Applied to 746 marketed...... drugs, a network of 1018 side effect-driven drug-drug relations became apparent, 261 of which are formed by chemically dissimilar drugs from different therapeutic indications. We experimentally tested 20 of these unexpected drug-drug relations and validated 13 implied drug-target relations by in vitro...... binding assays, of which 11 reveal inhibition constants equal to less than 10 micromolar. Nine of these were tested and confirmed in cell assays, documenting the feasibility of using phenotypic information to infer molecular interactions and hinting at new uses of marketed drugs....

    Insomnia is a self-reported disease where patients lose their ability to initiate and maintain sleep, leading to daytime performance impairment. Several drug targets to ameliorate insomnia symptoms have been discovered; however, these drug targets lead to serious side effects. Thus, we characterize the structural properties of these sleep-related receptors and the clock complex and discuss a possible drug design that will reduce side effects. Computational prediction shows that disordered property is shared. Over 30% of the structure of CLOCK, PER1/2/3, BMAL-1, muscarinic acetylcholine receptor-M1, melatonin receptor and casein kinase I are structurally disordered (the remaining proteins represent insomnia drugs might be closely related to the protein architecture.

    The immune system describes the body's ability to defend itself against various foreign intruders named as antigens by calling on an immune mechanism. Antigens penetration into body activate the body's immune system that may be humoral response, cellular response, or both. The immune response is primarily mediated by two cell types, lymphocyte and macrophage. This paper will discuss the cellular component of immune system and the radiation effects on various cells involved in system. Moreover, the effects of radiation on humoral and cellular responses and the relation among immunity, cancer and radiotherapy are also described. (author)

    Pinworms are highly contagious parasites that have been effectively treated in laboratory rodents with fenbendazole (FBZ). Whether FBZ has any detrimental side effects that may compromise experimental results is unknown. Here we asked whether the immune systems from young and aged mice are altered under FBZ treatment. We compared control and FBZ-treated groups of young (age, 2 to 4 mo) and old (age, 22 to 24 mo) BALB/cN mice. The treated mice received a total of 4 wk (alternating-week treatment regimen) of FBZ-medicated feed. Spleen and bone marrow were collected for immunologic assays, and heart, stomach, intestines, kidneys, and liver were evaluated by histopathology. Our results indicate that FBZ treatment has significant effects on the immune systems of mice; these effects are greater in aged mice. FBZ treatment adversely affected mRNA and protein expression of E2A (a transcription factor crucial for B lymphocytes) in activated precursor B lymphocytes obtained from the bone marrow of young and old mice. These effects were reversed by 6 wk on regular feed after the end of treatment. Activated B lymphocytes from the spleens of young and old mice showed decreased function (cell proliferation, E2A mRNA and protein expression) through the last time point of FBZ treatment but recovered by 2 to 4 wk after treatment. Our findings suggest that FBZ treatment may alter sensitive immune and molecular measures as presented here, and postponing the experimental use of mice until at least 6 wk after treatment should be considered.

    Local skin reactions to subcutaneous injections of interferon beta (IFNB) or glatiramer acetate (GA) in multiple sclerosis (MS) are frequent, while severe cutaneous toxicity is rare. Both IFNB and GA are immunomodulatory drugs that have excellent safety profiles and are currently used for treatment of MS. They are administered by SC injection every other day for IFNB-1b, three times a week for IFNB-1a or daily for 20 mg for GA. The most common adverse effects, which occur in approximately 20-60% of patients, include pain, inflammation and induration at the injection sites. Another adverse effect is frank panniculitis followed by localized lipoatrophy at the injection sites, which has been described in half of the patients receiving GA injections but is also described with Subcutaneous IFNB-1b. No guidelines have yet been established for the treatment of skin reactions, which is a frequent point for discussion between neurologists and dermatologists. In addition, no treatment has been found for established lipoatrophy. The prevention and management of cutaneous side-effects include patient education, regular examination and manual palpation of all injection sites. Non-steroid antiinflammatory gels, local corticosteroids or endermology can help patients to resolve side-effects and to continue immunomodulatory treatment.

    We have presented a case showing a major side-effect following metrizamide CT cisternography. The patient was a 68-year-old woman who developed anaphylactic shock and a disturbance of consciousness 6 hours after metrizamide CT cisternography with a dose of 850 mg of iodine. In spite of vigorous therapy, she died 60 hours after the shock. Examples of anaphylactic shock by metrizamide administered intrathecally have been reported very rarely. The pathogenesis of this case was presumably due to anaphylactic shock, but other etiological factors, such as a hypothalamic dysfunction due to a disturbed glucose metabolism of the brain, may also be suspected.

Outbreak-related cases of mumps born between 1995 and 2005 notified to Navarre and Catalonia public health services during the period 2005-2007 were studied. Vaccine effectiveness (VE) and their 95%CI were calculated using the screening method. Of 47 confirmed, 85.1% immunized with at least one dose (1MMR) and 44.9% with two (2MMR). Estimated VE was 85.4% (95%CI: 67.3-93.4) for 1MMR and 88.5% (95%CI: 78.1-93.9) for 2MMR. High 2MMR coverage, improved confirmation techniques and further VE studies with all confirmed cases are needed to prevent further outbreaks. (c) 2010 Elsevier Ltd. All rights reserved.

    Full Text Available The core of the digital transition is the representation of all kinds of real-world entities and processes and an increasing number of cognitive processes by digital information and algorithms on computers. These allow for seemingly unlimited storage, operation, retrieval, and transmission capacities that make digital tools economically available for all domains of society and empower human action, particularly combined with real-world interfaces such as displays, robots, sensors, 3D printers, etc. Digital technologies are general-purpose technologies providing unprecedented potential benefits for sustainability. However, they will bring about a multitude of potential unintended side effects, and this demands a transdisciplinary discussion on unwanted societal changes as well as a shift in science from analog to digital modeling and structure. Although social discourse has begun, the topical scope and regional coverage have been limited. Here, we report on an expert roundtable on digital transition held in February 2017 in Tokyo, Japan. Drawing on a variety of disciplinary backgrounds, our discussions highlight the importance of cultural contexts and the need to bridge local and global conversations. Although Japanese experts did mention side effects, their focus was on how to ensure that AI and robots could coexist with humans. Such a perspective is not well appreciated everywhere outside Japan. Stakeholder dialogues have already begun in Japan, but greater efforts are needed to engage a broader collection of experts in addition to stakeholders to broaden the social debate.

Concerning inhalant allergens, the safety of SLIT is overall superior to that of subcutaneous immunotherapy in terms of systemic adverse events. No fatality has been ever reported, and episodes of anaphylaxis were described only exceptionally. Looking at the historical and recent trials, most (>90%) adverse events are "local" and confined to the site of administration. For this reason, a specific grading system has been developed by the World Allergy Organization to classify and describe local adverse events. There is an increasing amount of literature concerning oral desensitization for food allergens, referred to as oral immunotherapy. Also, in this case, local side effects are predominant, although systemic adverse events are more frequent than with inhalant allergens. We review herein the description of local side effects due to SLIT, with a special focus on large trials having a declared sample size calculation. The use of the Medical Dictionary for Regulatory Activities nomenclature for adverse events is mentioned in this context, as recommended by regulatory agencies. It is expected that a uniform classification/grading of local adverse events will improve and harmonize the surveillance and reporting on the safety of SLIT.

    The interaction between complement fragment C3d and complement receptor 2 (CR2) is a key aspect of complement immune system activation, and is a component in a link between innate and adaptive immunities. The complement immune system is an ancient mechanism for defense, and can be found in species that have been on Earth for the last 600 million years. However, the link between the complement system and adaptive immunity, which is formed through the association of the B-cell co-receptor complex, including the C3d-CR2 interaction, is a much more recent adaptation. Human C3d and CR2 have net charges of -1 and +7 respectively, and are believed to have evolved favoring the role of electrostatics in their functions. To investigate the role of electrostatics in the function and evolution of human C3d and CR2, we have applied electrostatic similarity methods to identify regions of evolutionarily conserved electrostatic potential based on 24 homologues of complement C3d and 4 homologues of CR2. We also examine the effects of structural perturbation, as introduced through molecular dynamics and mutations, on spatial distributions of electrostatic potential to identify perturbation resistant regions, generated by so-called electrostatic "hot-spots". Distributions of electrostatic similarity based on families of perturbed structures illustrate the presence of electrostatic "hot-spots" at the two functional sites of C3d, while the surface of CR2 lacks electrostatic "hot-spots" despite its excessively positive nature. We propose that the electrostatic "hot-spots" of C3d have evolved to optimize its dual-functionality (covalently attaching to pathogen surfaces and interaction with CR2), which are both necessary for the formation B-cell co-receptor complexes. Comparison of the perturbation resistance of the electrostatic character of the homologues of C3d suggests that there was an emergence of a new role of electrostatics, and a transition in the function of C3d, after the

    The aim of this study was to investigate the effect of vitamine-A deficiency on the induction of specific periodontal pathogenic bacteria A. actinomycetetemcomitans(Aa) immunization. BALB/c mice were fed with vitamine A-depleted diet or control regular diet throughout the whole experiment period. After 2 weeks, immunized formalin-killed Aa to build immunized models, 6 weeks later, sacrificed to determine specific antibody-IgG, IgM and sub-class IgG antibody titers in serum, and concentration of IL-10, IFN-γ, TNF-α and RANKL in T cell supernatant were measured by ELISA and T cell proliferation was measured by cintilography. SPSS 11.5 software package was used for statistical analysis. The levels of whole IgG and IgM antibody which were immunized by Aa significantly elevated, non-immune group was unable to produce any antibody. Compared with Aa immunized+RD group, the level of whole IgG in Aa immunized+VAD group was significantly higher (Pvitamin-A diet can increase the immunized mice's susceptibility to periodontal pathogenic bacteria and trigger or aggravate immune inflammatory response. Adequate vitamin A is an important factor in maintaining body health.

    Antiarrhythmic drugs are commonly prescribed cardiac drugs. Due to their receptor mimicry with several of the gastrointestinal tract receptors, they can frequently lead to gastrointestinal side effects. These side effects are the most common reasons for discontinuation of these drugs by the patients. Knowledge of these side effects is important for clinicians that manage antiarrhythmic drugs. This review focuses on the gastrointestinal side effects of these drugs and provides a detailed up-to-date literature review of the side effects of these drugs. The review provides case reports reported in the literature as well as possible mechanisms that lead to gastrointestinal side effects.

    Resistance of mice to challenge infections of Schistosoma mansoni was evaluated before and after elimination of their primary, established S. mansoni infections with the chemotherapeutic drug praziquantel. Mice treated after either 10 or 20 weeks of primary infection were challenged 6 or 10 weeks after treatment. Mice infected for for 10 weeks prior to treatment expressed progressively less resistance 6 and 10 weeks after treatment. By 10 weeks after treatment significant levels of protection were no longer observed. Resistance waned more slowly if mice were treated 20 weeks after infection, and there was still significant expression of resistance to challenge 10 weeks after treatment. A separate set of experiments evaluated the use of highly irradiated cercariae as a vaccine in mice that had been previously infected with S. mansoni and cured with praziquantel. It was observed that effective immunizations were possible in previously infected mice. These studies demonstrate that established resistance waned after treatment and the rate of loss of protection was dependent upon the duration of infection prior to treatment. Furthermore, the irradiated cercarial vaccine studies indicate that in the murine model induction of immunological resistance was feasible following chemotherapeutic treatment of infected populations

    Early life adversity (ELA) is associated with a higher risk for diseases in adulthood. Although the pathophysiological effects of ELA are varied, there may be a unifying role for the immune system in all of the long-term pathologies such as chronic inflammatory disorders (autoimmune diseases, allergy, and asthma). Recently, significant efforts have been made to elucidate the long-term effects ELA has on immune function, as well as the mechanisms underlying these immune changes. In this review, we focus on data from human studies investigating immune parameters in relation to post-natal adverse experiences. We describe the current understanding of the 'ELA immune phenotype', characterized by inflammation, impairment of the cellular immune system, and immunosenescence. However, at present, data addressing specific immune functions are limited and there is a need for high-quality, well powered, longitudinal studies to unravel cause from effect. Besides the immune system, also the stress system and health behaviors are altered in ELA. We discuss probable underlying mechanisms based on epigenetic programming that could explain the ELA immune phenotype and whether this is a direct effect of immune programming or an indirect consequence of changes in behavior or stress reactivity. Understanding the underlying mechanisms will help define effective strategies to prevent or counteract negative ELA-associated outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

  7. Side-effects of improving CERN's spam filter

    CERN Multimedia

    2004-01-01

    To further improve the fight against spam (unsolicited email), CERN implemented in June a mechanism that returns electronic mail messages to the sender if the originating server is wrongly configured. This "reverse DNS lookup" is an increasingly widespread technique to identify whether the sending e-mail server is legitimate and has a valid host name. This change has nearly doubled the spam rejection efficiency at CERN. However, it has a known side-effect. A small number of correspondents are sending legitimate electronic mail to CERN from mail servers that are incorrectly configured (in technical terms, they do not have a reverse DNS registration). These persons will have their messages returned to them with an error message, provided their sender address is valid. The typical error message that the correspondent receives in such cases is "Relaying denied. No reverse DNS configured for IP". If a correspondent complains to you that emails they are sending you at CERN are being returned with...

    Tripeptide tyroserleutide (YSL) is a novel small molecule anti-tumor polypeptide that has been shown to inhibit the growth of human liver cancer cells. In this study, we investigated the effects of YSL plus doxorubicin on the growth of human hepatocellular carcinoma BEL-7402 cells that had been transplanted into nude mice. Nude mice bearing human hepatocellular carcinoma BEL-7402 tumors were treated with successive intraperitoneal injections of saline; low-, mid-, or high-dose doxorubicin; or low-, mid-, or high-dose doxorubicin plus YSL. Effects on the weight and volume of the tumors were evaluated. Co-administration of YSL and high-dose doxorubicin (6 mg/kg every other day) prolonged the survival time of tumor-bearing mice as compared to high-dose doxorubicin alone. As well, the anti-tumor effects of mid- and low-dose doxorubicin (2 and 0.7 mg/kg every other day, respectively) were enhanced when supplemented with YSL; the tumor growth inhibition rates for YSL plus doxorubicin were greater than the inhibition rates for the same dosages of doxorubicin alone. The combination of YSL and doxorubicin decreased chemotherapy-associated weight loss, leukocyte depression, and heart, liver, and kidney damage as compared to doxorubicin alone. The combination of YSL plus doxorubicin enhances the anti-tumor effect and reduces the side effects associated with doxorubicin chemotherapy

    Minoxidil, a vasodilator medication known for its ability to slow or stop hair loss and promote hair regrowth, was first introduced, exclusively as an oral drug, to treat high blood pressure. It was however discovered to have the important side-effect of increasing growth or darkening of fine body hairs; this led to the development of a topical formulation as a 2% concentration solution for the treatment of female androgenic alopecia or 5% for treating male androgenic alopecia. Measurable changes disappear within months after discontinuation of treatment. The mechanism by which it promotes hair growth is not fully understood. Minoxidil is a potassium channel opener, causing hyperpolarization of cell membranes and it is also a vasodilator, it is speculated that, by widening blood vessels and opening potassium channels, it allows more oxygen, blood and nutrients to the follicle. This can also cause follicles in the telogen phase to shed, usually soon to be replaced by new, thicker hairs in a new anagen phase. It needs to be applied regularly, once or twice daily, for hair gained to be maintained, and side effects are common. The most common adverse reactions of the topical formulation are limited to irritant and allergic contact dermatitis on the scalp. There have been cases of allergic reactions to the nonactive ingredient propylene glycol, which is found in some topical solution especially if they are galenic. Increased hair loss which can occur during Minoxidil use, is due to the synchronization of the hair cycle that the treatment induces. In this review, we described its mechanism of action, use in dermatology and some patents related to alternative treatment of allergic reactions due to its use.

  12. The sweet side of a long pentraxin: how glycosylation affects PTX3 functions in innate immunity and inflammation

    Directory of Open Access Journals (Sweden)

    Antonio eInforzato

    2013-01-01

    Full Text Available Innate immunity represents the first line of defence against pathogens and plays key roles in activation and orientation of the adaptive immune response. The innate immune system comprises both a cellular and a humoral arm. Components of the humoral arm include soluble pattern recognition molecules (PRMs that recognise pathogen associated molecular patterns (PAMPs and initiate the immune response in coordination with the cellular arm, therefore acting as functional ancestors of antibodies. The long pentraxin PTX3 is a prototypic soluble PRM that is produced at sites of infection and inflammation by both somatic and immune cells. Gene targeting of this evolutionarily conserved protein has revealed a non-redundant role in resistance to selected pathogens. Moreover, PTX3 exerts important functions at the crossroad between innate immunity, inflammation and female fertility. The human PTX3 protein contains a single N-glycosylation site that is fully occupied by complex type oligosaccharides, mainly fucosylated and sialylated biantennary glycans. Glycosylation has been implicated in a number of PTX3 activities, including neutralization of influenza viruses, modulation of the complement system, and attenuation of leukocyte recruitment. Therefore, this post translational modification might act as a fine tuner of PTX3 functions in native immunity and inflammation.Here we review the studies on PTX3, with emphasis on the glycan-dependent mechanisms underlying pathogen recognition and crosstalk with other components of the innate immune system.

    To extract physician-asserted drug side effects from electronic medical record clinical narratives. Pattern matching rules were manually developed through examining keywords and expression patterns of side effects to discover an individual side effect and causative drug relationship. A combination of machine learning (C4.5) using side effect keyword features and pattern matching rules was used to extract sentences that contain side effect and causative drug pairs, enabling the system to discover most side effect occurrences. Our system was implemented as a module within the clinical Text Analysis and Knowledge Extraction System. The system was tested in the domain of psychiatry and psychology. The rule-based system extracting side effects and causative drugs produced an F score of 0.80 (0.55 excluding allergy section). The hybrid system identifying side effect sentences had an F score of 0.75 (0.56 excluding allergy section) but covered more side effect and causative drug pairs than individual side effect extraction. The rule-based system was able to identify most side effects expressed by clear indication words. More sophisticated semantic processing is required to handle complex side effect descriptions in the narrative. We demonstrated that our system can be trained to identify sentences with complex side effect descriptions that can be submitted to a human expert for further abstraction. Our system was able to extract most physician-asserted drug side effects. It can be used in either an automated mode for side effect extraction or semi-automated mode to identify side effect sentences that can significantly simplify abstraction by a human expert.

    Drug side effects are one of main concerns in the drug discovery, which gains wide attentions. Investigating drug side effects is of great importance, and the computational prediction can help to guide wet experiments. As far as we known, a great number of computational methods have been proposed for the side effect predictions. The assumption that similar drugs may induce same side effects is usually employed for modeling, and how to calculate the drug-drug similarity is critical in the side effect predictions. In this paper, we present a novel measure of drug-drug similarity named "linear neighborhood similarity", which is calculated in a drug feature space by exploring linear neighborhood relationship. Then, we transfer the similarity from the feature space into the side effect space, and predict drug side effects by propagating known side effect information through a similarity-based graph. Under a unified frame based on the linear neighborhood similarity, we propose method "LNSM" and its extension "LNSM-SMI" to predict side effects of new drugs, and propose the method "LNSM-MSE" to predict unobserved side effect of approved drugs. We evaluate the performances of LNSM and LNSM-SMI in predicting side effects of new drugs, and evaluate the performances of LNSM-MSE in predicting missing side effects of approved drugs. The results demonstrate that the linear neighborhood similarity can improve the performances of side effect prediction, and the linear neighborhood similarity-based methods can outperform existing side effect prediction methods. More importantly, the proposed methods can predict side effects of new drugs as well as unobserved side effects of approved drugs under a unified frame.

    Purpose: Despite increased utilization of fractionated stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS), the incidence and nature of immediate side effects (ISE) associated with these treatment techniques are not well defined. We report immediate side effects from a series of 78 patients. Materials and Methods: Intracranial lesions in 78 adult patients were treated with SRT or SRS, using a dedicated linear accelerator. Those lesions included 13 gliomas, 2 ependymomas, 19 metastatic tumors, 15 meningiomas, 12 acoustic neuromas, 4 pituitary adenomas, 1 optic neuroma, 1 chondrosarcoma, and 11 arteriovenous malformations (AVM). SRT was used in 51 and SRS in 27 patients. Mean target volume was 9.0 cc. Eleven patients received prior external-beam radiation therapy within 2 months before SRT/SRS. Any side effects occurring during and up to 2 weeks after the course of radiation were defined as ISE and were graded as mild, moderate, or severe. The incidence of ISE and the significance of their association with several treatment and pretreatment variables were analyzed. Results: Overall, 28 (35%) of 78 patients experienced one or more ISE. Most of the ISE (87%) were mild, and consisted of nausea (in 5), dizziness/vertigo (in 5), seizures (in 6), and new persistent headaches (in 17). Two episodes of worsening neurological deficit and 2 of orbital pain were graded as moderate. Two patients experienced severe ISE, requiring hospitalization (1 seizure and 1 worsening neurological deficit). ISE in 6 cases prompted computerized tomography of the brain, which revealed increased perilesional edema in 3 cases. The incidence of ISE by diagnosis was as follows: 46% (6 of 13) for gliomas, 50% (6 of 12) for acoustic neuromas, 36% (4 of 11) for AVM, 33% (5 of 15) for meningiomas, and 21% (4 of 19) for metastases. A higher incidence of dizziness/vertigo (4 of 12 = 33%) was seen among acoustic neuroma patients than among other patients (p < 0.01). There was no

    The impact of electronic health record (EHR) immunization clinical alert systems on the delivery of other preventive services remains unknown. We assessed for spillover effects of an EHR immunization alert on delivery of 6 other preventive services, in children 18 to 30 months of age needing immunizations. We conducted a secondary data analysis, with additional primary data collection, of a randomized, historically controlled trial to improve immunization rates with EHR alerts, in an urban, primary care clinic. No significant differences were found in screening for anemia, lead, development, nutrition, and injury prevention counseling in children prompting EHR immunization alerts (n = 129), compared with controls (n = 135). Significant increases in oral health screening in patients prompting EHR alerts (odds ratio = 4.8, 95% CI = 1.8-13.0) were likely due to practice changes over time. An EHR clinical alert system targeting immunizations did not have a spillover effect on the delivery of other preventive services.

    Full Text Available Background: Control of balance is a complex motor skill that involves integration of sensory inputs and the planning and execution of flexible movement patterns. Carrying side packs is famous in our society especially shoulder side packs. Most students carry shoulder side packs and they don't care about the way to carry them to be more balanced. The purpose of the study is to investigate the effect of carrying shoulder side pack on dynamic postural stability and to determine the best way of carrying a shoulder side pack either on the dominant side or non-dominant side that doesn’t affect dynamic postural stability in young healthy female. Methods: Sixty female volunteers aged from 18 to 25 years old participated in the study. Biodex balance system was used to measure the dynamic postural stability in three different occasions (without carrying a shoulder side pack, with carrying a shoulder side pack on the dominant side, and on the non-dominant side with a rest period in between. Results: Repeated measure analysis of variance (ANOVA followed by Bonferroni post hoc test were used to compare dynamic posture balance without carrying and during carrying a shoulder side pack on dominant and non-dominant sides. Analysis revealed that overall, anteroposterior and mediolateral stability indexes reduced significantly (P<0.0001 when carrying shoulder side pack on dominant side in comparison with when carrying shoulder side pack on non-dominant side and without carrying bag. Conclusion: It was concluded that carrying a shoulder side pack on the non-dominant side didn't disturb the postural stability when compared to carrying on the dominant side so, we recommend the students to carry shoulder side packs on the non-dominant side.

    Innate immunity that protects against pathogens in the tissues and circulation is the first line of defense in the immune reaction, where macrophages have a critical role in directing the fate of the infection. We recently demonstrated that kefir modulates the immune response in mice, increasing the number of IgA+ cells in the intestinal and bronchial mucosa and the phagocytic activity of peritoneal and pulmonary macrophages. The aim of this study was to further characterize the immunomodulating capacity of the two fractions of kefir (F1: solids including bacteria and F2: liquid supernatant), by studying the cytokines produced by cells from the innate immune system: peritoneal macrophages and the adherent cells from Peyer's patches. BALB/c mice were fed either kefir solid fraction (F1) or kefir supernatant (F2) for 2, 5 or 7 consecutive days. The number of cytokine (IL-1alpha, IFNgamma, TNFalpha, IL-6 and IL-10) producing cells was determined on peritoneal macrophages and adherent cells from Peyer's patches. Both kefir fractions (F1 and F2) induced similar cytokine profiles on peritoneal macrophages (only TNFalpha and IL-6 were up-regulated). All cytokines studied on adherent cells from Peyer's patches were enhanced after F1 and F2 feeding, except for IFNgamma after F2 administration. Moreover, the percentage of IL-10+cells induced by fraction F2 on adherent cells from Peyer's patches was significantly higher than the one induced by fraction F1. Different components of kefir have an in vivo role as oral biotherapeutic substances capable of stimulating immune cells of the innate immune system, to down-regulate the Th2 immune phenotype or to promote cell-mediated immune responses against tumours and also against intracellular pathogenic infections.

  20. Statin Therapy: Review of Safety and Potential Side Effects.

    Hydroxymethyl glutaryl coenzyme A reductase inhibitors, commonly called statins, are some of the most commonly prescribed medications worldwide. Evidence suggests that statin therapy has significant mortality and morbidity benefit for both primary and secondary prevention from cardiovascular disease. Nonetheless, concern has been expressed regarding the adverse effects of long term statin use. The purpose of this article was to review the current medical literature regarding the safety of statins. Major trials and review articles on the safety of statins were identified in a search of the MEDLINE database from 1980 to 2016, which was limited to English articles. Myalgia is the most common side effect of statin use, with documented rates from 1-10%. Rhabdomyolysis is the most serious adverse effect from statin use, though it occurs quite rarely (less than 0.1%). The most common risk factors for statin-related myopathy include hypothyroidism, polypharmacy and alcohol abuse. Derangement in liver function tests is common, affecting up to 1% of patients; however, the clinical significance of this is unknown. Some statin drugs are potentially diabetogenic and the risk appears to increase in those patients on higher doses. Pitavastatin has not been associated with increased risk of diabetes. Statins have not been proven to increase the risk of malignancy, dementia, mood disorders or acute interstitial nephritis. However, statins do have multiple drug interactions, primarily those which interact with the cytochrome p450 enzyme group. Overall, statin drugs appear to be safe for use in the vast majority of patients. However, patients with multiple medical co-morbidities are at increased risk of adverse effects from long-term statin use.

Design and setting A prospective database study of all patients admitted to the burn centres (Beverwijk, Groningen, Rotterdam) and the hospital emergency departments in the Netherlands. Method Number and extent of burn injuries as a result of steam inhalation therapy were analysed, as well as an approximation made of the direct costs for their medical treatment. Results Annually, on average three people are admitted to in one of the Dutch burn centres for burns resulting from steam inhalation therapy. Most victims were children, and they needed skin grafting more often than adults. The total direct medical costs for burn centre and emergency department treatment were €115 500 (£93 000), emotional costs are not reflected. Conclusion As steam inhalation therapy has no proven benefit and the number and extent of complications of this therapy in terms of burn injury are significant, especially in children, steam inhalation therapy should be considered a dangerous procedure and not recommended anymore in professional guidelines and patient brochures.

    Temozolomide (TMZ) is an alkylating agent primarily used to treat tumors of the central nervous system. We describe 2 patients with apparent TMZ-induced central diabetes insipidus. Using our institution's Research Patient Database Registry, we identified 3 additional potential cases of TMZ-induced diabetes insipidus among a group of 1545 patients treated with TMZ. A 53-year-old male with an oligoastrocytoma and a 38-year-old male with an oligodendroglioma each developed symptoms of polydipsia and polyuria approximately 2 months after the initiation of TMZ. Laboratory analyses demonstrated hypernatremia and urinary concentrating defects, consistent with the presence of diabetes insipidus, and the patients were successfully treated with desmopressin acetate. Desmopressin acetate was withdrawn after the discontinuation of TMZ, and diabetes insipidus did not recur. Magnetic resonance imaging of the pituitary and hypothalamus was unremarkable apart from the absence of a posterior pituitary bright spot in both of the cases. Anterior pituitary function tests were normal in both cases. Using the Research Patient Database Registry database, we identified the 2 index cases and 3 additional potential cases of diabetes insipidus for an estimated prevalence of 0.3% (5 cases of diabetes insipidus per 1545 patients prescribed TMZ). Central diabetes insipidus is a rare but reversible side effect of treatment with TMZ.

    Full Text Available Photodynamic Therapy (PDT is a non-invasive treatment successfully used for neoplastic, inflammatory and infectious skin diseases. One of its strengths is represented by the high safety profile, even in elderly and/or immuno-depressed subjects. PDT, however, may induce early and late onset side effects. Erythema, pain, burns, edema, itching, desquamation, and pustular formation, often in association with each other, are frequently observed in course of exposure to the light source and in the hours/days immediately after the therapy. In particular, pain is a clinically relevant short-term complication that also reduces long-term patient satisfaction. Rare complications are urticaria, contact dermatitis at the site of application of the photosensitizer, and erosive pustular dermatosis. Debated is the relationship between PDT and carcinogenesis: the eruptive appearance of squamous cell carcinoma (SCC in previously treated areas has been correlated to a condition of local and/or systemic immunosuppression or to the selection of PDT-resistant SCC. Here we review the literature, with particular emphasis to the pathogenic hypotheses underlying these observations.

    Between April 1984 and December 1985 we treated ten children suffering from neuroblastoma in a total of 25 metaiodobenzylguanidine (MIBG) courses. Five had had a relapse of neuroblastoma stage III or IV, three had never achieved a remission in spite of intensive chemotherapy, and two were treated with an unstable remission. The children were each administered from 1 to 5 courses with a dosage per course of between 1295 and 9065 MBq. The sum of the single doses during the whole course of therapy ranged between 3145 and 21,904 MBq per child. Five of five children suffering from bone pain and fever became free of complaints during the first three treatment days. Six of eight children with manifest tumor at onset of therapy responded well to the treatment: response extended from transitory decrease in elevated catecholamine levels in serum and urine to complete disappearance of large abdominal tumor masses. We also observed a decrease in bone marrow involvement and a stabilization of osteolytic lesions. Seven of these eight children died in spite of a good response from 55 to 350 days after the first MIBG treatment course. The only side effect we witnessed was a reversible bone marrow depression. In three children we combined the MIBG therapy with bone marrow transplantation

    Full Text Available Aim of the study : To evaluate an association between food products consumption, dietary intake and the incidence of selected gastrointestinal symptoms (nausea, vomiting, diarrhea and constipation in cancer patients undergoing chemotherapy. Material and methods : Fifty six women receiving chemotherapy for ovarian cancer were eligible for the study. Anthropometrical measurements were assessed. The dietary intake was evaluated by 24-hours food records. The association between the consumption of selected food products and gastrointestinal symptoms incidences was assessed by modified semi-quantitative food frequency questionnaire including 77-different food items that was developed and applied in cancer patients undergoing chemotherapy. Results : BMI values indicated 9%, 45%, 30% and 16% of patients as underweight, normal weight, overweight and obese respectively. Only 23% and 32% of patients never experienced nausea and constipation when 43% and 45% never experienced vomiting and diarrhea. Nausea was promoted by oils, constipation by chocolate and chocolate products and diarrhea by dairy products, stone fruit and apple. Significant inverse correlations were found between vomiting and the intake of energy, fat, protein, carbohydrates, B groups vitamins, vitamin D, phosphorus and zinc. The difference in energy intake between marginal values of vomiting incidence exceeded 400 kcal. Conclusions : Dietary intake as well as specific food products influence on gastrointestinal side effect of chemotherapy in cancer patients. The dietary approach based on either exclusion or limited intake of selected food products and improvement of diet could reduce and prevent chemotherapy induced gastrointestinal symptoms therefore should be taken under consideration in clinical practice.

    Side effects prompt some patients to forego otherwise-beneficial therapies. This study explored which characteristics make side effects particularly aversive. We used a psychometric approach, originating from research on risk perception, to identify the factors (or components) underlying side effect perceptions. Women ( N = 149) aged 40 to 74 years were recruited from a patient registry to complete an online experiment. Participants were presented with hypothetical scenarios in which an effective and necessary medication conferred a small risk of a single side effect (e.g., nausea, dizziness). They rated a broad range of side effects on several characteristics (e.g., embarrassing, treatable). In addition, we collected 4 measures of aversiveness for each side effect: choosing to take the medication, willingness to pay to avoid the side effect (WTP), negative affective attitude associated with the side effect, and how each side effect ranks among others in terms of undesirability. A principal components analysis (PCA) was used to identify the components underlying side effect perceptions. Then, for each aversiveness measure separately, regression analyses were used to determine which components predicted differences in aversiveness among the side effects. The PCA revealed 4 components underlying side effect perceptions: affective challenge (e.g., frightening), social challenge (e.g., disfiguring), physical challenge (e.g., painful), and familiarity (e.g., common). Side effects perceived as affectively and physically challenging elicited the highest levels of aversiveness across all 4 measures. Understanding what side effect characteristics are most aversive may inform interventions to improve medical decisions and facilitate the translation of novel biomedical therapies into clinical practice.

    Purpose/Objective: Despite increased utilization of fractionated stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS), the incidence and nature of immediate side effects (ISE) associated with these treatment techniques is not well defined. Materials and Methods: Intracranial lesions in 78 adult patients were treated with SRT or SRS, using a dedicated linear accelerator. They comprised 13 gliomas, 2 ependymomas, 19 metastatic tumors, 15 meningiomas, 12 acoustic neuromas, 4 pituitary adenomas, 1 optic neuroma, 1 chondrosarcoma and 11 arteriovenous malformations (AVM). SRT was used in 51 and SRS in 27 patients. Mean target volume was 9.0 cc. Eleven patients received prior external beam radiation therapy within 2 months before SRT/SRS. Any side effects occurring during and up to two weeks after radiation course were defined as ISE and were graded as mild, moderate or severe. The incidence of ISE and the significance of their association with several pretreatment variables were analyzed. Results: Overall, (28(78)) (35%) patients experienced one or more ISE. Most of ISE (87%) were mild and consisted of nausea (5), dizziness/vertigo (5), seizures (7) and new persistent headaches (17). Two episodes of worsening neurological deficit and 2 of orbital pain were graded as moderate. Two patients experienced severe ISE, requiring hospitalization (1 seizure and 1 worsening neurological deficit). ISE in 5 cases prompted computerized tomography of the brain which revealed increased perilesional edema in 3 cases. The incidence of ISE by diagnosis was as follows: 46% ((6(13))) for gliomas, 50% ((6(12))) for acoustic neuromas, 36% ((4(11))) for AVM, 33% ((5(15))) for meningiomas and 21% ((4(19))) for metastases. Increasing dose to the margin and increasing maximum dose were associated with a higher incidence of ISE (p=0.02 and 0.005, respectively).

  9. Effects of utility demand-side management programs on uncertainty

    Electric utilities face a variety of uncertainties that complicate their long-term resource planning. These uncertainties include future economic and load growths, fuel prices, environmental and economic regulations, performance of existing power plants, cost and availability of purchased power, and the costs and performance of new demand and supply resources. As utilities increasingly turn to demand-side management (DSM) programs to provide resources, it becomes more important to analyze the interactions between these programs and the uncertainties facing utilities. This paper uses a dynamic planning model to quantify the uncertainty effects of supply-only vs DSM + supply resource portfolios. The analysis considers four sets of uncertainties: economic growth, fuel prices, the costs to build new power plants, and the costs to operate DSM programs. The two types of portfolios are tested against these four sets of uncertainties for the period 1990 to 2010. Sensitivity, scenario, and worst-case analysis methods are used. The sensitivity analyses show that the DSM + supply resource portfolio is less sensitive to unanticipated changes in economic growth, fuel prices, and power-plant construction costs than is the supply-only portfolio. The supply-only resource mix is better only with respect to uncertainties about the costs of DSM programs. The base-case analysis shows that including DSM programs in the utility's resource portfolio reduces the net present value of revenue requirements (NPV-RR) by 490 million dollars. The scenario-analysis results show an additional 30 million dollars (6%) in benefits associated with reduction in these uncertainties. In the worst-case analysis, the DSM + supply portfolio again reduces the cost penalty associated with guessing wrong for both cases, when the utility plans for high needs and learns it has low needs and vice versa. 20 refs

    Intraoral devices have increasingly assumed a key role in the treatment of obstructive sleep apnea syndrome, but there are limitations to their indication and side effects that result from their continuous use, as well as the use of the continuous positive airway pressure device. To evaluate the changes in dental positioning caused by the continuous use of mandibular advancement devices. A prospective longitudinal study with a sample of 15 patients, with evaluation of complete documentation after a mean time of 6.47 months, assessed changes in dental positioning due to the use of the Twin Block oral device for the treatment of patients with apnea. The following variables were evaluated: overjet, overbite, upper and lower intermolar distances, upper and lower intercanine distances, Little's irregularity index and the incisor mandibular plane angle. An intraclass correlation test was performed and a correlation index>0.08 was accepted. After verifying the normal sample distribution (Shapiro-Wilks), a parametric test was used (t test), with a significance level set at 5%. There was a decrease in the values of overjet, overbite and Little's irregularity index, whereas there was an increase in the lower intercanine distance and IMPA values. All these variables are influenced, at different levels, by the forward inclination of the lower incisors, an action that can be expected due to the force applied by the device on the dentition. The other variables did not show statistically significant differences. After a mean time of 6.47 months of use of the mandibular advancement device, there were statistically significant changes in the dental positioning, but they were not clinically relevant. However, it is relevant that this device is commonly in use over long periods of time, making the monitoring of these patients of the utmost importance for the duration of their therapy.

    Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side-effects are common. No validated self-rating scale measuring side-effects to CPAP treatment exists today. The aim was to develop the side-effects to CPAP treatment inventory (SECI), and investigate the validity and reliability of the instrument among patients with OSAS. SECI was developed on the basis of: (1) in-depth interviews with 23 patients; (2) examination of the scientific literature and (3) consensus agreement of a multi-professional expert panel. This yielded 15 different types of side-effects related to CPAP treatment. Each side-effect has three sub-questions (scales): perceived frequency (a) and magnitude (b) of the side-effect, as well as its perceived impact on CPAP use (c). A cross-sectional descriptive design was used. A total of 329 patients with OSAS with an average use of CPAP treatment for 39 months (2 weeks to 182 months) were recruited. Data were collected with SECI, and obtained from medical records (clinical variables and data related to CPAP treatment). Construct validity was confirmed with factor analysis (principal component analysis with orthogonal rotation). A logical two-factor solution, the device subscale and symptom subscale, emerged across all three scales. The symptom subscale describing physical and psychological side-effects and the device subscale described mask and device-related side-effects. Internal consistency reliability of the three scales was good (Cronbach's α = 0.74-0.86) and acceptable for the subscales (Cronbach's α = 0.62-0.86). The satisfactory measurement properties of this new instrument are promising and indicate that SECI can be used to measure side-effects to CPAP treatment. © 2010 European Sleep Research Society.

    Purpose: Proton minibeam radiation therapy is a novel approach to minimize normal tissue damage in the entrance channel by spatial fractionation while keeping tumor control through a homogeneous tumor dose using beam widening with an increasing track length. In the present study, the dose distributions for homogeneous broad beam and minibeam irradiation sessions were simulated. Also, in an animal study, acute normal tissue side effects of proton minibeam irradiation were compared with homogeneous irradiation in a tumor-free mouse ear model to account for the complex effects on the immune system and vasculature in an in vivo normal tissue model. Methods and Materials: At the ion microprobe SNAKE, 20-MeV protons were administered to the central part (7.2 × 7.2 mm{sup 2}) of the ear of BALB/c mice, using either a homogeneous field with a dose of 60 Gy or 16 minibeams with a nominal 6000 Gy (4 × 4 minibeams, size 0.18 × 0.18 mm{sup 2}, with a distance of 1.8 mm). The same average dose was used over the irradiated area. Results: No ear swelling or other skin reactions were observed at any point after minibeam irradiation. In contrast, significant ear swelling (up to fourfold), erythema, and desquamation developed in homogeneously irradiated ears 3 to 4 weeks after irradiation. Hair loss and the disappearance of sebaceous glands were only detected in the homogeneously irradiated fields. Conclusions: These results show that proton minibeam radiation therapy results in reduced adverse effects compared with conventional homogeneous broad-beam irradiation and, therefore, might have the potential to decrease the incidence of side effects resulting from clinical proton and/or heavy ion therapy.

    A mathematical model, simulating the effect of ionizing radiation on the dynamics of humoral immune reaction is suggested. It represents the system of nonlinear differential equations and is realized in the form of program in Fortran computer language. The model describes the primary immune reaction of nonirradiated organism on T-independent antigen, reflects the postradiation lymphopoiesis dynamics in nonimmunized mammals, simulates the processes of injury and recovery of the humoral immunity system under the combined effect of ionizing radiation and antigenic stimulation. The model can be used for forecasting imminity state in irradiated mammals

    Serotonin [5-hydroxytryptamine (5-HT)] plays an important role in many organs as a peripheral hormone. Most of the body’s serotonin is circulating in the bloodstream, transported by blood platelets and is released upon activation. The functions of serotonin are mediated by members of the 7 known mammalian serotonin receptor subtype classes (15 known subtypes), the serotonin transporter (SERT), and by covalent binding of serotonin to different effector proteins. Almost all immune cells express...

    Antithymocyte globulins (ATGs) are part of the immunosuppression arsenal currently used by clinicians to prevent or treat acute rejection in solid organ transplantation. ATG is a mixture of non-specific anti-lymphocyte immunoglobulins targeting not only T cell subsets but also several other immune and non-immune cells, rendering its precise immunoglobulin composition difficult to appreciate or to compare from one preparation to another. Furthermore, several mechanisms of action have been described. Taken together, this probably explains the efficacy and the side effects associated with this drug. Recent data suggest a long-term negative impact on allograft and patient outcomes, pointing out the need to better characterize the potential toxicity and the benefit-risk balance associated to this immunosuppressive therapy within large clinical trials. © The Author 2016.

    In this project, we aimed to obtain the preclinical in vivo evaluation data for the development of the herbal composition (HemoHIM) as the auxiliary agent for the anticancer treatment that can reduce the side-effects of anticancer drugs and enhance their anticancer activities. Firstly, in vitro studies showed that HemoHIM did not show any effects on the tumor cell growth inhibition by 2 anticancer drugs (cisplatin, 5-FU), which indicated that at least HemoHIM does not exert any adverse effects on the activities of anticancer drugs. Next, the in vivo studies with mice implanted with tumor cells(B16F0, LLC1) showed that HemoHIM partially enhanced the anticancer activities of drugs (cisplatin, 5-FU), and improved endogenous anticancer immune activities. Furthermore, in the same animal models, HemoHIM effectively reduced the side-effects of anticancer drugs (liver and renal toxicities by cisplatin, immune and hematopoietic disorders by 5-FU). These results collectively showed that HemoHIM can enhance the activities of anticancer drugs and reduce their side-effects in vitro and in vivo and HemoHIM does not exert any adverse effects on the efficacy of anticancer drugs. The results of this project can be utilized as the basic preclinical data for the development and approval of HemoHIM as the auxiliary agent for the anticancer treatment

    Full Text Available Interferons alpha and beta have been used worldwide for a few decades, altering the natural history of several severe diseases including hepatitis C, cancer and immune-mediated conditions such as multiple sclerosis. The adverse events profile of interferons is well established, but only isolated reports of ophthalmological complications of interferon therapy have been published. The objective of this study was to carry out a literature systematic review on the subject, bringing to light the need for careful ophthalmological monitoring of patients undergoing interferon treatment. Nearly 500 cases of ophthalmological complications related to interferon have been reported. The most frequent findings were soft exudates, hemorrhages and retina ischemia.

    1986-01-01

    After reviewing the different lymphoid organs and the essential phases of the immune response, we studied the morphological and functional effects of ionizing radiation on the immunological system. Histologic changes in the lymph nodes, spleen, thymus, and different lymphocyte subpopulations were studied in relation with the radiation dose and irradiated volume (whole body irradiation, localized irradiation). Functional changes in the immune system induced by ionizing radiation were also investigated by a study of humoral-mediated immunity (antibody formation) and cell-mediated immunity (behavior of macrophages, B-cells, T suppressor cells, T helper cells, T effector cells, and natural killer cells). A study into the mechanisms of action of ionizing radiation and the immune processes it interferes with suggests several likely hypotheses (direct action on the immune cells, on their precursors, on seric mediators or on cell mediators). The effects on cancer patients' immune reactions of low radiation doses delivered to the various lymphoid organs are discussed, as well as the relationships between the host and the evolution of the tumor [fr

    Side effects from hormonal therapy (HT) for breast cancer treatment occur frequently and are associated with worse quality of life and HT non-adherence. Whether improved patient-physician communication is associated with patients' reporting of side effects is unknown. We undertook this study to assess factors associated with women's reports of HT side effects. Between December 2012 and April 2013, we conducted a cross-sectional survey of breast cancer patients undergoing HT in an urban medical center. Descriptive statistics, univariate analyses, and multivariate analyses were used to evaluate associations. Of the 100 participants, 67% reported having HT side effects. However, when prompted, an additional 9% reported experiencing specific HT-related symptoms. Despite very high communication scores, one-third of participants reported they had not discussed side effects with providers. Multivariate analysis showed that after controlling for age, education, race, and medication beliefs, women who had difficulty asking providers for more information were more likely to report side effects (odds ratio 8.27, 95% confidence interval 1.01-69.88). Although HT side effects often occur and are bothersome, patient-provider discussions about side effects remain suboptimal. Providers should actively ask patients about medication side effects so that they can be addressed to improve quality of life and potentially, medication adherence.

    Side effects are central to the experience of living longer with HIV but rarely have they been studied alone. Unlike other aspects of that experience, like quality of life, treatment adherence, chronicity, episodic disability, aging, health, and viral load suppression, side effects have not benefited from the same level of empirical and theoretical engagement from qualitative researchers. In this paper, we draw on syndemics theory and 50 qualitative interviews to better understand the experience of HIV treatment side effects. Two main categories were identified in the data: side effects as a product and side effects as a risk factor. The first category suggests that side effects are not just the product of taking antiretroviral drugs. They are also the product of particular conditions and tend to cluster with other health problems. The second category puts forward the idea that side effects can act as a syndemic risk factor by exposing PLWH to a greater risk of developing health problems and creating conditions in which psychosocial issues are more likely to emerge. The paper concludes by calling for more research on the complex nature of side effects and for the development of comprehensive approaches for the assessment and management of side effects.

    High-quality BN-Graphene-BN nanoribbon capacitors with double side-gates of graphene have been experimentally realized. The double side-gates can effectively modulate the electronic properties of graphene nanoribbon capacitors. By applying anti-symmetric side-gate voltages, we observed significant upward shifting and flattening of the V-shaped capacitance curve near the charge neutrality point. Symmetric side-gate voltages, however, only resulted in tilted upward shifting along the opposite direction of applied gate voltages. These modulation effects followed the behavior of graphene nanoribbons predicted theoretically for metallic side-gate modulation. The negative quantum capacitance phenomenon predicted by numerical simulations for graphene nanoribbons modulated by graphene side-gates was not observed, possibly due to the weakened interactions between the graphene nanoribbon and side-gate electrodes caused by the Ga + beam etching process

    Branding medication with a known pharmaceutical company name or product name bestows on the drug an added assurance of authenticity and effectiveness compared to a generic preparation. This study examined the impact of brand name and generic labeling on medication effectiveness and side effects. 87 undergraduate students with frequent headaches took part in the study. Using a within-subjects counterbalanced design, each participant took tablets labeled either as brand name "Nurofen" or "Generic Ibuprofen" to treat each of 4 headaches. In reality, half of the tablets were placebos, and half were active ibuprofen (400 mg). Participants recorded their headache pain on a verbal descriptor and visual analogue scale prior to taking the tablets, and again 1 hour afterward. Medication side effects were also reported. Pain reduction following the use of brand name labeled tablets was similar in active ibuprofen or a placebo. However, if the tablets had a generic label, placebo tablets were significantly less effective compared to active ibuprofen. Fewer side effects were attributed to placebo tablets with brand name labeling compared to the same placebo tablets with a generic label. Branding of a tablet appears to have conferred a treatment benefit in the absence of an active ingredient, while generic labeled tablets were substantially less effective if they contained no active ingredient. Branding is also associated with reduced attribution of side effects to placebo tablets. Future interventions to improve perceptions of generics may have utility in improving treatment outcomes from generic drugs. (c) 2016 APA, all rights reserved).

    Full Text Available Aparna Jain,1 Laura Reichenbach,1 Iqbal Ehsan,2 Ubaidur Rob2 1Evidence Project, Population Council, Washington, DC, USA; 2Evidence Project, Population Council, Dhaka, Bangladesh Purpose: In a country like Bangladesh that has made great progress in contraceptive use with one of the lowest levels of fertility and highest levels of contraceptive use, understanding what factors influence women’s decisions to discontinue a contraceptive method and not switch to a new method is critical in designing interventions and programs that will help enable Bangladesh to reach its FP2020 goals. Research on side effects has focused on physical manifestations like headaches, moodiness, abdominal pain, and menstrual irregularities. While physical effects alone may stop women from continuing a contraceptive method, less is known about how side effects influence women’s daily activities and lives. The purpose of this study is to understand the ways that side effects affect Bangladeshi women’s participation in different social settings.Methods: Thirty-five in-depth interviews with married women who recently discontinued or switched to a different contraceptive method were conducted in Sylhet and Khulna Divisions. Interviews explored reasons for discontinuation including experience of side effects and impact of side effects on women’s lives.Results: Key themes emerged including that side effects are not only experienced physically but are barriers to women’s participation in many aspects of their lives. The spheres of life that most commonly appeared to be influenced by side effects include religion, household, and sexual intimacy irrespective of method used or residence.Conclusion: Family planning providers need to be aware of these additional consequences associated with contraceptive side effects to provide tailored counseling that recognizes these issues and helps women to mitigate them. For Bangladesh to achieve its FP2020 goals, understanding the

    The immunity booster is, according to its patent description, microbiologically pure water with an D/(D+H) isotopic concentration of 100 ppm, with physical-chemical characteristics similar to those of distilled water. It is obtained by sterilization of a mixture of deuterium depleted water, with a 25 ppm isotopic concentration, with distilled water in a volume ratio of 4:6. Unlike natural immunity boosters (bacterial agents as Bacillus Chalmette-Guerin, Corynebacterium parvum; lipopolysaccharides; human immunoglobulin) or synthetical products (levamysol; isoprinosyne with immunostimulating action), which cause hypersensitivity and shocks, thrill, fever, sickness and the immunity complex disease, the water of 100 ppm D/(D + H) isotopic concentration is a toxicity free product. The testing for immune reaction of the immunity booster led to the following results: - an increase of cell action capacity in the first immunity shielding stage (macrophages), as evidenced by stimulation of a number of essential characterizing parameters, as well as of the phagocytosis capacity, bactericide capacity, and opsonic capacity of serum; - an increase of the number of leucocyte particularly of the granulocyte in peripheral blood, produced especially when medullar toxic agents like caryolysine are used; - it hinders the effect of lowering the number of erythrocytes in peripheral blood produced by experimentally induced chronic inflammation; - an increase of nonspecific immunity defence capacity against specific bacterial aggression of both Gram-positive bacteria (Streptococcus pneumoniae 558 ) and of the Gram-negative ones (Klebsiella pneumoniae 507 ); - an increase of immunity - stimulating activity (proinflamatory), like that of levamisole as evidenced by the test of stimulation of experimentally induced inflammation by means of carrageenan. The following advantages of the immunity booster are stressed: - it is toxicity free and side effect free; - can be orally administrated as

    Delayed radiation effects of irradiation at relatively high doses - 0.52- 2 Gy in result of severe accidents are discussed. The immune response of lymphocyte populations manifested in formation of different kind of mutant cells at Hiroshima-A-bombing and Chernobyl accident are presented. It is of great interest the hypothesis presented launched by RERF (Japanese Foundation for Radiation Effect Research, Hiroshima) for radiation induced predominant of T H2 -lymphocytes in comparison to T H1 as delayed immune response at the Hiroshima-A-bomb survivors. The aspect of immune status is quite different at low doses irradiation (0.02 - 0.2 Gy). There is some stimulation in immune response known as hormesis effect. It is suggested that T-cell activation has key role in immune system stimulation at doses under 0.2 Gy. There is also activation of DNA-reparation mechanisms. Suppression of the hypothalamus-hypophysis-suprarenal axis brings to enhancing of immune potential. Chinese people living in a region with three-times higher background radiation, X-ray examined patients as well as occupationally exposed personnel have been investigated. Radioprotective effect of some cytokines and their influence on the individual radiosensitivity are also discussed.The investigations have to be continued because of some inconsistent results

    Full Text Available Vertebrate mothers transfer diverse compounds to developing embryos that can affect their development and final phenotype (i.e., maternal effects. However, the way such effects modulate offspring phenotype, in particular their immunity, remains unclear. To test the impact of maternal effects on offspring development, we treated wild breeding house sparrows (Passer domesticus in Sevilla, SE Spain with Newcastle disease virus (NDV vaccine. Female parents were vaccinated when caring for first broods, eliciting a specific immune response to NDV. The immune response to the same vaccine, and to the PHA inflammatory test were measured in 11-day-old chicks from their following brood. Vaccinated chicks from vaccinated mothers developed a stronger specific response that was related to maternal NDV antibody concentration while rearing their chicks. The chicks’ carotenoid concentration and total antioxidant capacity in blood were negatively related to NDV antibody concentration, whereas no relation with PHA response was found. Specific NDV antibodies could not be detected in 11-day-old control chicks from vaccinated mothers, implying that maternally transmitted antibodies are not directly involved but may promote offspring specific immunity through a priming effect, while other immunity components remain unaffected. Maternally transmitted antibodies in the house sparrow are short-lived, depend on maternal circulation levels and enhance pre-fledging chick specific immunity when exposed to the same pathogens as the mothers.

    The purpose of this study was to characterize the effects of chronic low-dose ionizing radiation (LDR) on murine immune cells. Previously, it had been reported that LDR enhances the proliferative activity of T cells in vitro and delays the growth of transplantable immunogenic tumors in vivo. This suggests that LDR eliminates immune suppressor cells, which downregulates immune response and/or adoptively upregulates the responsiveness of immune effector cells. It had also been reported that human lymphocytes become refractive to high dose radiation-induced chromosomal aberrations by pretreating mitotically active lymphocytes in vitro with very low doses of ionizing radiation, and the adaptive effect can be abrogated by cycloheximide. This suggests that protein synthesis is required for lymphocytes to respond adoptively to LDR

    Management of recurrent cervical cancer by reirradiation after radiation treatment remains controversial. In Indonesia, there is currently no data about reirradiation tumor response and side effects. This study aims to assess the tumor response to and side effects of reirradiation, the effect of time interval between first radiation treatment and cancer recurrence on the tumor response and side effects, and the effect of tumor size on tumor response. A cohort retrospective study with no comparison was done with the Radiotherapy Department at Cipto Mangunkusumo General Hospital, Jakarta. Participants were recurrent cervical cancer patients undergoing reirradiation. Data was collected from patients’ medical records and follow-up phone calls. Twenty-two patients participated in this study. Nine patients (40.9%) had complete responses, 10 patients (45.5%) had partial responses, 1 patient (4.5%) had a stable response, and 2 patients (9.1%) had tumor progressions. In general, 15 patients (68.2%) had no to light side effects (grade 0-2 RTOG) and 7 patients (31.8%) had severe side effects (grade 3-4 RTOG). Four patients (18.1%) had severe gastrointestinal acute side effects, 6 patients (27.3%) had severe gastrointestinal late side effects, 2 patients (9.1%) had severe urogenital side effects, and there were no patients had severe urogenital late side effects. There was no significant difference in tumor response between patients with time interval between first radiation treatment and recurrence of 4 cm. Reirradiation can be considered as a modality in recurrent cervical cancer management since good tumor response was achieved and the majority of patients had no to light side effects (grade 0-2 RTOG). This study found no correlation between tumor response, side effects, and time gap between first radiation treatment and recurrence of 4 cm.

    Nowadays, use of prebiotics as feed and food additives has received increasing interest because of the beneficial effects of prebiotics on the health of animals and humans. One of the beneficial effects of prebiotics is stimulation of immune system, which can be direct or indirect through increasing population of beneficial microbes or probiotics, especially lactic acid bacteria and bifidobacteria, in the gut. An important mechanism of action of probiotics and prebiotics, by which they can affect the immune system, is changing the expression of cytokines. The present review tried to summarize the findings of studies that investigated the effects of prebiotics on immune system with focusing on their effects on cytokine expression. Generally, most of reviewed studies indicated beneficial effects for prebiotics in terms of improving immune system, by increasing the expression of anti-inflammatory cytokines, while reducing the expressions of proinflammatory cytokines. However, most of studies mainly considered the indirect effects of prebiotics on the immune system (through changing the composition and population of gut microbiota), and their direct effects still need to be further studied using prebiotics with different degree of polymerization in different hosts.

    Full Text Available Purpose. To study and summarize the existing evidence base for the use of melatonin as a mean to counteract or diminish the side effects of various psychotropic drugs and electroconvulsive therapy, and to provide the reader with relevant conclusions. Methodology. The authors have searched for the scientific literature regarding the use of melatonin as a mean to counteract or diminish the side effects of various psychotropic drugs and electroconvulsive therapy, using the PubMed and Google Scholar as a search tool. Then the authors thoroughly reviewed the data they found. The resulting review is presented in this article. Results. The data we have obtained from this review of the literature indicate that melatonin can be effectively used both in monotherapy and in combination with other therapeutic means in order to reduce several different side effects of psychotropic drugs and electroconvulsive therapy. Melatonin also deserves further study in this regard. The evidence base for its use in this manner is very variable in quality for different side effects. For now, the greatest evidence base exists regarding the potential effectiveness of melatonin in the prevention and treatment of drug-induced insomnia, memory and cognitive impairment, akathisia, tardive dyskinesias, and metabolic syndrome. Practical implications. The results we have obtained can be widely applied in psychiatry, neurology and addiction medicine, as well as in all those areas of general medicine, which make use of psychotropic drugs.

    Flow around two rotating side-by-side circular cylinders of equal diameter D is numerically studied at the Reynolds number 40≤ Re ≤200 and various rotation rate θ i . The incoming flow is assumed to be two-dimensional laminar flow. The governing equations are the incompressible Navier-Stokes equations and solved by the finite volume method (FVM). The ratio of the center-to-center spacing to the cylinder diameter is T/D=2. The objective of the present work is to investigate the effect of rotational speed and Reynolds number on the stability of the flow. The simulation results are compared with the experimental data and a good agreement is achieved. The stability of the flow is analyzed by using the energy gradient theory, which produces the energy gradient function K to identify the region where the flow is the most prone to be destabilized and the degree of the destabilization. Numerical results reveal that K is the most significant at the separated shear layers of the cylinder pair. With Re increases, the length of the wake is shorter and the vortex shedding generally exhibits a symmetrical distribution for θ i < θ crit . It is also shown that the unsteady vortex shedding can be suppressed by rotating the cylinders in the counter-rotating mode.

    Full Text Available In August/1999, a group of 14 adults from the staff of a private hospital in Contagem -- Minas Gerais State, Brazil, received unintentionally a 25 times concentrated dose of the 17-DD yellow fever vaccine (Bio-Manguinhos, due to a mistake at the reconstitution step. All patients were clinically and laboratorially evaluated at days 5, 13 and 35 post vaccination. Frequency of side effects and clinical observations of this group of individuals were not different from the observed in recipients immunized with normal doses of the vaccine. At the second and third evaluation none of the subjects reported symptoms. None of the patients presented abnormalities at the physical examination at none of the time points and in all cases the blood examination was normal, except for a reduced number of platelets that was detected in one subject at the first and second evaluation and reverted to normal at third evaluation. At the first evaluation point, 8 subjects were serum negative and 6 serum positive for yellow fever at the plaque reduction neutralization test. In 5 subjects the observed titre was 10 times higher as the baseline of 2.36 Log10 mUI/ml. The samples collected at second and third evaluation (13th and 35th days demonstrated that all subjects responded to the vaccination with the exception of one that did not present a positive result in any of the samples collected. This evaluation confirms the safety of the 17-DD yellow fever vaccine.

  20. Effects of ultraviolet radiation on the immune system in humans

    Morison, W.L.

    1989-01-01

    In experimental animals, exposure to UV-B radiation produces selective alterations of immune function which are mainly in the form of suppression of normal immune responses. This immune suppression is important in the development of nonmelanoma skin cancer, may influence the development and course of infectious disease and possibly protects against autoimmune reactions. The evidence that this form of immune suppression occurs in humans is less compelling and very incomplete. The wavelengths of radiation most affected by a depletion of the stratospheric ozone layer are those known to be most immunosuppressive in animals and it is likely that such depletion will increase any suppressive effect of sunlight on immunity in humans. In addition to establishing whether or not UV-B radiation can cause suppression of immune function in humans, studies are required to determine if melanin can provide protection against such suppression, the role of this suppression in the pathogenesis of skin cancer, the development of infectious disease and vaccine effectiveness, and the capacity for humans to develop adaptive, protective mechanisms which may limit damage from continued exposure to UV-B radiation.

    Full Text Available Patricia PoirierUniversity of Maine School of Nursing, Orono, ME, USAAbstract: It has been estimated that 50%–60% of patients diagnosed with cancer will receive radiation therapy at some point in their treatment. Although radiation therapy can play a significant role in the cure or control of cancer, and the palliation of symptoms, it also has side effects. Side effects of radiation therapy can interfere with patient quality of life and daily functioning. Severe side effects can lead to delays in treatment, potentially affecting the outcome of treatment. All patients receiving radiation therapy are at risk of fatigue and skin reactions in the area of the body being treated. Other side effects of radiation therapy are specific to the part of the body being treated. Radiation therapy to the head and neck area may cause oral mucositis, dryness, and nutritional deficiencies. Radiation therapy to the chest or lung area may lead to difficulty in swallowing and eating. Radiation therapy to the pelvis frequently causes diarrhea. There are many nursing interventions available to manage the side effects of treatment based on best available evidence and expert opinion. Nurses in all settings are essential in helping patients manage the side effects of treatment and maintain their quality of life. The purpose of this review is to provide nurses with evidence-based recommendations and suggestions for managing common acute side effects of radiation therapy.Keywords: evidence-based practice, radiation therapy, side effects, nursing management

    Prediction of adverse drug reactions is an important problem in drug discovery endeavors which can be addressed with data-driven strategies. SIDER is one of the most reliable and frequently used datasets for identification of key features as well as building machine learning models for side effects prediction. The inherently unbalanced nature of this data presents with a difficult multi-label multi-class problem towards prediction of drug side effects. We highlight the intrinsic issue with SIDER data and methodological flaws in relying on performance measures such as AUC while attempting to predict side effects.We argue for the use of metrics that are robust to class imbalance for evaluation of classifiers. Importantly, we present a 'hierarchical anatomical classification schema' which aggregates side effects into organs, sub-systems, and systems. With the help of a weighted performance measure, using 5-fold cross-validation we show that this strategy facilitates biologically meaningful side effects prediction at different levels of anatomical hierarchy. By implementing various machine learning classifiers we show that Random Forest model yields best classification accuracy at each level of coarse-graining. The manually curated, hierarchical schema for side effects can also serve as the basis of future studies towards prediction of adverse reactions and identification of key features linked to specific organ systems. Our study provides a strategy for hierarchical classification of side effects rooted in the anatomy and can pave the way for calibrated expert systems for multi-level prediction of side effects.

  7. Radiotherapy and antitumor immunity. An immunomodifying effect of ionizing radiation

    1983-01-01

    It has been found that a tumor is formed and spread under the influence of opposite but not mutually exlusive immune reactions. Radiation effect along with direct injury of tumoral cells and feeding neoplasms vessels changes the established equilibrium of immunologic factors, therefore it should be considered as immunomodifying one. The wide spread opinion according to which the therapeutic effect in case of radiotherapy is attained despite its depressive effect on immunity, should be revised as not corresponding to the facts. The data available allow one to assume that immunologic factors may play an essential role in realization of therapeutic effect of irradiation as well as in limitation of its efficiency. Investigations into immunologic aspects of oncology and radiology should be therefore directed to the search of methods of control of immune reactions of organism - the tumor bearer. This may discover considerable reserves of increasing radiotherapeutic efficiency

    In the present study the side effects of adjuvant radiotherapy of testicular seminoma stage I patients were followed up in the period between 13 to 84 months (median 28 months). The most frequent side effects in these patients during radiotherapy were gastrointestinal problems (nausea/vomiting), psychologic and cognitive problems and minor sexual problems. The reported side effects were treated by antimmimetics and anxiolytics. After radiotherapy, the side effects persisted in 6 % of patients but therapy was needed only in few. Healthy children were born to 76 % of patients in the age group 18 - 39 years after radiotherapy. The present study shows that adjuvant irradiation of paraaortal lymph nodes with total a dose of 24 Gy in 16 daily fractions in testicular seminoma patients causes acceptable side effects with acceptable quality of life and fertility, however in conditions of individual approach and family consulting.

    In semiconductor manufacturing, as the design rule has decreased, the ITRS roadmap requires crucial tighter critical dimension (CD) control. CD uniformity is one of the necessary parameters to assure good performance and reliable functionality of any integrated circuit (IC) [1] [2], and towards the advanced technology nodes, it is a challenge to control CD uniformity well. The study of corresponding CD Uniformity by tuning Post-Exposure bake (PEB) and develop process has some significant progress[3], but CD side to side error happening to some line/space pattern are still found in practical application, and the error has approached to over the uniformity tolerance. After details analysis, even though use several developer types, the CD side to side error has not been found significant relationship to the developing. In addition, it is impossible to correct the CD side to side error by electron beam correction as such error does not appear in all Line/Space pattern masks. In this paper the root cause of CD side to side error is analyzed and the PEB module process are optimized as a main factor for improvement of CD side to side error.

    One of the major factors contributing to parental refusal of vaccinations is the perception that vaccines cause side effects. Although symptoms are commonly reported following vaccinations, their causes are not always straightforward. Although some may be directly attributable to the vaccine itself, others may reflect pre-existing or coincidental symptoms that are misattributed to the vaccine. To investigate psychological factors associated with parental report of side effects following vaccination with the child influenza vaccine, and parental intention to re-vaccinate one's child the following year. A prospective cohort study was run in primary care practices in London in the 2016-2017 influenza season (ClinicalTrials.gov number NCT02909855). Two hundred seventy parents from 14 practices completed a questionnaire before their child's vaccination. Follow-up questionnaires were completed 3 days after vaccination and one month after vaccination. Parental report of side effects and vaccination intention for the subsequent year were measured. Parental report of side effects was strongly associated with pre-vaccination expectation of side effects. Suggestions received from the media, National Health Service (NHS) vaccination leaflet, and health care workers, as well as uncertainty-related beliefs, perceived sensitivity of the child to medicines, pessimism, and anxiety were also associated with reporting side effects. Side effect report was associated with lower vaccination intention for the following influenza season. Side effect perception following vaccination is influenced by psychological factors, in particular expectations. Perceiving side effects reduces future vaccination intention. Future public health communications should aim to decrease unrealistic expectations of side effects to increase vaccine uptake.

    Besides providing optimal nutrition to infants, human milk contains a multitude of immunological components. These components are important for protection against infections and also support the development and maturation of the infant's own immune system. This review focuses on the function of some classical immunocomponents of human milk. Relevant studies are presented that describe health benefits of human milk for the child and of lactation for the mother. Relevant articles were found mainly by searching PubMed. Humoral and cellular components of human milk confer protection against infections in the respiratory--, gastrointestinal--and urinary tract. Human milk also protects premature children from neonatal sepsis and necrotizing enterocolitis. There is evidence that human milk may confer long-term benefits such as lower risk of certain autoimmune diseases, inflammatory bowel disease and probably some malignancies. Human milk possibly affects components of the metabolic syndrome. Recent studies demonstrate long-term health benefits of lactation also for the mother. A reduced incidence of breast cancer is best documented. An increasing number of studies indicate protection against ovarian cancer, rheumatoid arthritis and type II diabetes.

    Understanding individual differences in susceptibility to antidepressant therapy side-effects is essential to optimize the treatment of depression. We performed genome-wide association studies (GWAS) to search for genetic variation affecting the susceptibility to side-effects. The analysis sample consisted of 1439 depression patients, successfully genotyped for 421K single nucleotide polymorphisms (SNPs), from the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study. Outcomes included four indicators of side-effects: general side-effect burden, sexual side-effects, dizziness and vision/hearing-related side-effects. Our criterion for genome-wide significance was a prespecified threshold ensuring that, on average, only 10% of the significant findings are false discoveries. Thirty-four SNPs satisfied this criterion. The top finding indicated that 10 SNPs in SACM1L mediated the effects of bupropion on sexual side-effects (p = 4.98 × 10(-7), q = 0.023). Suggestive findings were also found for SNPs in MAGI2, DTWD1, WDFY4 and CHL1. Although our findings require replication and functional validation, this study demonstrates the potential of GWAS to discover genes and pathways that could mediate adverse effects of antidepressant medication.

    Affecting about 1 in 12 Americans annually, depression is a leading cause of the global disease burden. While a range of effective antidepressants are now available, failure and relapse rates remain substantial, with intolerable side effect burden the most commonly cited reason for discontinuation. Thus, understanding individual differences in susceptibility to antidepressant therapy side effects will be essential to optimize depression treatment. Here we perform genome-wide association studies (GWAS) to identify genetic variation influencing susceptibility to citalopram-induced side effects. The analysis sample consisted of 1762 depression patients, successfully genotyped for 421K single-nucleotide polymorphisms (SNPs), from the Sequenced Treatment Alternatives to Relieve Depression (STAR(*)D) study. Outcomes included five indicators of citalopram side effects: general side effect burden, overall tolerability, sexual side effects, dizziness and vision/hearing side effects. Two SNPs met our genome-wide significance criterion (qeffects of citalopram on vision/hearing side effects (P=3.27 × 10(-8), q=0.026). The second genome-wide significant finding, representing a haplotype spanning ∼30 kb and eight genotyped SNPs in a gene desert on chromosome 13, was associated with general side effect burden (P=3.22 × 10(-7), q=0.096). Suggestive findings were also found for SNPs at LAMA1, AOX2P, EGFLAM, FHIT and RTP2. Although our findings require replication and functional validation, this study demonstrates the potential of GWAS to discover genes and pathways that potentially mediate adverse effects of antidepressant medications.

    Based on a newly developed model that integrates energy production, transformation and consumption processes, this paper compares the relative importance of some traditionally recognized factors operating on the energy demand side with a body of newly defined factors on the supply side, in terms of their contribution to trends in China's CO 2 emissions related to the total primary energy supply (C-TPES). Before 1996, changes in China's C-TPES were mainly driven by changes on the energy demand side. Factors operating on the energy supply side played trivial roles. During the period 1996-2000, however, increasing demand-side effects declined dramatically and at the same time decreasing effects from supply side expanded significantly. Such changes resulted directly in a decline in the C-TPES. The decreasing effects from international trade as well as statistical imbalances between supply and demand reinforced the declining trend. The shrinkage of demand side effects mainly arose from the slowdown of economic growth and speed of decrease in energy intensity. The expansion of supply-side effects was principally attributed to the speed of decrease in gross unit consumption in transformation sectors, especially in electricity sector. Therefore, the acceleration of efficiency improvements in end-use and transformation sectors accounted for the decline in the C-TPES over the period 1996-2000. (author)

    In a series of experiments carried out on young and adult rabbits the effect of isocaloric low protein diets containing 4% or 8% protein compared with a diet containing 21% protein on Obeliscoides cuniculi infection was studied. The pathogenesis, resistance and local immunity were assessed after single infections with 10,000 larvae or reinfection with 5000 larvae. Live weight gain was reduced in young and adult rabbits fed the low protein diets, but the establishment of parasites was not substantially influenced by protein deprivation. However, development of worms in the histotrophic phase and parasite fecundity were impaired in association with the low protein diet. Moreover, mild anaemia as well as changes in the mucosal immune response as a result of infection were related to the level of dietary protein. (author). 30 refs, 6 figs, 5 tabs

    Studies have shown that produced water (PW) discharged from North Sea offshore platforms affects the biota at greater distances from operational platforms than originally presumed. According to PW dispersion simulations, dilution by at least 240 times occurs within 50-100 m, and up to 9000 times by 20 km from the discharge. In this study, the effect of PW on cod immunity was investigated by exposing fish to 0, 100 ppm (x 10,000 dilution) or 200 ppm (x 500) of PW for 76 days. Immune responses were evaluated at the end of the exposure. Fish from the 3 groups were injected with Aeromonas salmonicida lipopolysaccharides (LPS). Blood cell observation and flow cytometry were used to investigate the serum cortisol levels and gill histology along with ratios and respiratory burst (RB) responses of both circulating and head-kidney white blood cells (WBCs). The study revealed that baseline immunity and stress response were not affected by PW, other than an irritant-induced change in gill cells found in treated cod. In all groups, LPS injection resulted in a pronounced decrease in RB of head-kidney cells and an increase in serum cortisol and protein levels. However, the group exposed to 200 ppm of PW exhibited the most significant changes. LPS injection was also shown to influence WBC ratios, but further studies are needed to determine if this impact is stronger in fish exposed to PW. This study suggested an effect of PW on cod immunity after immune challenge with LPS.

    Phenobarbital remains one of the most widely used antiepileptic drugs worldwide, yet there are limited data regarding side effects associated with its use in routine clinical care settings in low-income countries. Available data suggests that phenobarbital is as effective as other first-line drugs for treating tonic-clonic seizures, but side effect reports differ widely between high and low-income settings. A better understanding of phenobarbital side effect profile and severity in low-income settings is warranted given its role in efforts to decrease the epilepsy treatment gap. We used the Liverpool adverse events profile (LEAP) to assess side effects in consecutive patients with epilepsy on phenobarbital seeking care in rural Zambia. Data regarding age, gender, medication dose, and medication adherence were also collected. T-tests and Spearman's correlation coefficient were used to assess predictors of LEAP score and medication adherence. Thirty-five patients receiving a mean dose of 2.1mg/kg/day (SD: 2.78 mg/kg/day) of phenobarbital were assessed. All participants reported at least one side effect in the previous four weeks with a median of 6 symptoms (IQR: 4-8) and a mean side effects score of 28/76 (SD: 5.38). Over half reported sleepiness and dizziness. Memory problems and depression were also common (both 46%). Total LAEP score was not associated with age (p=0.88), gender (p=0.17), or phenobarbital dose (p=0.13). Medication adherence was not associated with side effects total score (p=0.56). Rural Zambian adults taking phenobarbital at doses recommended by the World Health Organization report a significant number of side effects. The most common side effects reported were similar to those reported in high-income countries. The significant burden of phenobarbital-associated side effects in this African cohort is in contrast to data from non-randomized clinical trials in China that reported phenobarbital to be well-tolerated with few side effects.

    Diarrhea is one of the leading causes of death in children under 5, and an estimated 39% of these deaths are attributable to rotavirus. Currently two live, oral rotavirus vaccines have been introduced on the market; however, the herd immunity effect associated with rotavirus vaccine has not yet been quantified. The purpose of this meta-analysis was to estimate the herd immunity effects associated with rotavirus vaccines. We performed a systematic literature review of articles published between 2008 and 2014 that measured the impact of rotavirus vaccine on severe gastroenteritis (GE) morbidity or mortality. We assessed the quality of published studies using a standard protocol and conducted meta-analyses to estimate the herd immunity effect in children less than one year of age across all years presented in the studies. We conducted these analyses separately for studies reporting a rotavirus-specific GE outcome and those reporting an all-cause GE outcome. In studies reporting a rotavirus-specific GE outcome, four of five of which were conducted in the United States, the median herd effect across all study years was 22% [19-25%]. In studies reporting an all-cause GE outcome, all of which were conducted in Latin America, the median herd effect was 24.9% [11-30%]. There is evidence that rotavirus vaccination confers a herd immunity effect in children under one year of age in the United States and Latin American countries. Given the high variability in vaccine efficacy across regions, more studies are needed to better examine herd immunity effects in high mortality regions. Copyright © 2015 The Authors.

    The morbilliviruses measles virus (MeV) and canine distemper virus (CDV) both rely on two surface glycoproteins, the attachment (H) and fusion proteins, to promote fusion activity for viral cell entry. Growing evidence suggests that morbilliviruses infect multiple cell types by binding to distinct host cell surface receptors. Currently, the only known in vivo receptor used by morbilliviruses is CD150/SLAM, a molecule expressed in certain immune cells. Here we investigated the usage of multiple receptors by the highly virulent and demyelinating CDV strain A75/17. We based our study on the assumption that CDV-H may interact with receptors similar to those for MeV, and we conducted systematic alanine-scanning mutagenesis on CDV-H throughout one side of the β-propeller documented in MeV-H to contain multiple receptor-binding sites. Functional and biochemical assays performed with SLAM-expressing cells and primary canine epithelial keratinocytes identified 11 residues mutation of which selectively abrogated fusion in keratinocytes. Among these, four were identical to amino acids identified in MeV-H as residues contacting a putative receptor expressed in polarized epithelial cells. Strikingly, when mapped on a CDV-H structural model, all residues clustered in or around a recessed groove located on one side of CDV-H. In contrast, reported CDV-H mutants with SLAM-dependent fusion deficiencies were characterized by additional impairments to the promotion of fusion in keratinocytes. Furthermore, upon transfer of residues that selectively impaired fusion induction in keratinocytes into the CDV-H of the vaccine strain, fusion remained largely unaltered. Taken together, our results suggest that a restricted region on one side of CDV-H contains distinct and overlapping sites that control functional interaction with multiple receptors. PMID:21849439

    Lymphocytes are divided into 2 major classes: T and B lymphocytes (or cells). T cells are responsible for cell-mediated immune response, and B cells for humoral immune response or antibody formation. The possible immunological complications that might develop as the late manifestation of radiation effects include: lymphoid neoplasms, immune complex diseases, auto-aggressive immune reactions, and other degenerative diseases of immunological nature. The development of lymphoid neoplasma following the exposure to radiation was extensively studied with mice. Radiation-induced immunological compications would not contribute significantly to the life-shortening of exposed individuals. The extensive health survey of adult A-bomb survivors revealed little evidence of immunological complications such as rheumatoid arthritis, kidney diseases, paraproteinemia, etc. The young healthy adults who had received thymic irradiation during infancy for the treatment of enlarged thymus manifested higher incidence of illness with abnormal immunological features. Immune complex diseases, particularly the inter-capillary glomerulosclerosis of kidneys, develop as a result of earlier exposure to high dose of radiation. (Yamashita, S.)

    2015-01-01

    Recently, we have derived a novel and compact expression for how perturbations in the matter fields of the cosmological fluid can lead to deviations from the standard Friedmann equations. Remarkably, the dissipative damping of velocity perturbations by bulk and shear viscosity in the dark sector can modify the expansion history of the universe on arbitrarily large scales. In universes in which this effect is sufficiently sizeable, it could account for the acceleration of the cosmological expansion. But even if dark matter should be less viscous and if the effect would be correspondingly smaller, it may have observable consequences in the era of precision cosmology. Here, we review the origin of this backreaction effect and possibilities to constrain it further.

    Standard therapy in chronic hepatitis C virus infection is still a combination of peginterferon alfa2a/2b and ribavirin for 48 weeks. As of side effects, there are organic side effects, such as hematologic disorders, and functional side effects, reflected in the quality of life of hepatitis C patients. Up to 30% of the patients develop specific side effects such as headache, fever, fatigue. Sarcoidosis, known as a granulomatous disease of uncertain cause, is an uncommon finding in this category of patients. This cause-effect relation is accounted for by the convergent action of peginterferon and ribavirin of stimulating type 1 T helper cells and reducing type 2 helper T cells activation. We present the case of male patient known with chronic hepatitis C who developed pulmonary sarcoidosis following antiviral therapy. The first manifestation of the disease was unexplained fever accompanied by pulmonary tract disease. The diagnosis was established by immunophenotyping in bronchial aspirate

    Chemotherapy and radiation therapy (RT) are standard therapeutic modalities for patients with cancers, and could induce various tumor cell death modalities, releasing tumor-derived antigens as well as danger signals that could either be captured for triggering anti-tumor immune response. Historic studies examining tissue and cellular responses to RT have predominantly focused on damage caused to proliferating malignant cells leading to their death. However, there is increasing evidence that RT also leads to significant alterations in the tumor microenvironment, particularly with respect to effects on immune cells and infiltrating tumors. This review will focus on immunologic consequences of RT and discuss the therapeutic reprogramming of immune responses in tumors and how it regulates efficacy and durability to RT.

    Energy drinks are increasingly popular among athletes and others. Advertising for these products typically features images conjuring great muscle power and endurance; however, the scientific literature provides sparse evidence for an ergogenic role of energy drinks. Although the composition of energy drinks varies, most contain caffeine; carbohydrates, amino acids, herbs, and vitamins are other typical ingredients. This report analyzes the effects of energy drink ingredients on prolonged submaximal (endurance) exercise as well as on short-term strength and power (neuromuscular performance). It also analyzes the effects of energy drink ingredients on the fluid and electrolyte deficit during prolonged exercise. In several studies, energy drinks have been found to improve endurance performance, although the effects could be attributable to the caffeine and/or carbohydrate content. In contrast, fewer studies find an ergogenic effect of energy drinks on muscle strength and power. The existing data suggest that the caffeine dose given in studies of energy drinks is insufficient to enhance neuromuscular performance. Finally, it is unclear if energy drinks are the optimal vehicle to deliver caffeine when high doses are needed to improve neuromuscular performance. © 2014 International Life Sciences Institute.

    Virtual reality (VR) has become increasingly well-known over the last few years. However, little is known about the side-effects of prolonged immersion in VR. This study set out to investigate the frequency of occurrence and severity of side-effects of using an immersion VR system. Out of 146 subjects, 61% reported symptoms of malaise at some point during a 20-min immersion and 10-min post-immersion period. These ranged from symptoms such as dizziness, stomach awareness, headaches, eyestrain and lightheadedness to severe nausea. These symptoms caused 5% of the subjects to withdraw from the experiment before completing their 20-min immersion period. Further research needs to be conducted that attempts to identify those factors that play a causative role in the side-effects of the VR system, and that looks for methods of reducing these side-effects.

    Radioiodine treatment is considered to be the treatment of choice in benign thyroid diseases because of its very low side effects. Real and hypothetic risks and side effects have to be differentiated. Both may occur early and late after the treatment. Radioiodinethyroiditis in small volumes at high doses is very rare. Exacerbation of a thyroid storm (0.34%) as well as local compressions accompanied with reactive edema of the thyroid are early real side effects of radioiodine treatment. Late real side effects are failure of treatment (7-30% of thyrotoxicosis) and induction of hypothyroidism (4-20% of functional autonomy and increasing frequency in Graves' diseases with time). Late hypothetic risks are somatic (1-9/10000 bis 1-9/100000) or genetic (1-9/100000). An early risk might be the misdiagnosis of an additional thyroid carcinoma. (orig.) [de

    Adolescent immunization rates for human papillomavirus (HPV) are low and interventions within school-based health centers (SBHCs) may increase HPV uptake and series completion. We examined the effect of a parent health message intervention on HPV vaccination intent, first dose uptake and series completion among adolescents who received care at SBHCs. Via computer-assisted telephone interviews (CATI), 445 parents of young adolescents were randomly assigned to 2 two-level interventions using a 2 × 2 design (rhetorical question (RQ) or no-RQ and one-sided or two-sided message). The RQ intervention involved asking the parent a question they were likely to endorse (e.g., "Do you want to protect your daughter from cervical cancer?") with the expectation that they would then behave in a manner consistent with their endorsement (i.e., agree to vaccinate). For the one-sided message, parents were given information that emphasized the safety and effectiveness of HPV vaccine, whereas the two-sided message acknowledged that some parents might have concerns about the vaccine, followed by reassurance regarding the safety and effectiveness. At CATI conclusion, parents indicated intentions to have their adolescents vaccinated. Parents who endorsed any intent were sent a consent form to return and all adolescents with signed returned consents were vaccinated at SBHCs. Medical records were reviewed for uptake/completion. Parents were 87% female; adolescents were 66% male and racially/ethnically diverse. 42.5% of parents indicated some intention to immunize, 51.4% were unsure, and 6.1% were not interested. 34% (n = 151) of adolescents received their first dose with series completion rates of 67% (n = 101). The RQ component of the intervention increased intention to vaccinate (RR = 1.45; 95%CI 1.16,1.81), but not first dose uptake or series completion. The 1-sided and 2-sided messages had no effect. This brief, RQ health intervention enhanced intent, but did not impact vaccination

  8. Study of ageing side effects in the DELPHI HPC calorimeter

    The readout proportional chambers of the HPC electromagnetic calorimeter in the DELPHI experiment are affected by large ageing. In order to study the long-term behaviour fo the calorimeter, one HPC module was extracted from DELPHI in 1992 and was brought to a test area where it was artificially aged during a period of two years; an ageing level exceeding the one expected for the HPC at the end of the LEP era was reached. During this period the performance of the module was periodically tested by means of dedicated beam tests whose results are discussed in this paper. These show that ageing has no significant effects on the response linearity and on the energy resolution for electromagnetic showers, once the analog response loss is compensated for by increasing the chamber gain through the anode voltage.

    Drug side effects represent a common reason for stopping drug development during clinical trials. Improving our ability to understand drug side effects is necessary to reduce attrition rates during drug development as well as the risk of discovering novel side effects in available drugs. Today, most investigations deal with isolated side effects and overlook possible redundancy and their frequent co-occurrence. In this work, drug annotations are collected from SIDER and DrugBank databases. Terms describing individual side effects reported in SIDER are clustered with a semantic similarity measure into term clusters (TCs). Maximal frequent itemsets are extracted from the resulting drug x TC binary table, leading to the identification of what we call side-effect profiles (SEPs). A SEP is defined as the longest combination of TCs which are shared by a significant number of drugs. Frequent SEPs are explored on the basis of integrated drug and target descriptors using two machine learning methods: decision-trees and inductive-logic programming. Although both methods yield explicit models, inductive-logic programming method performs relational learning and is able to exploit not only drug properties but also background knowledge. Learning efficiency is evaluated by cross-validation and direct testing with new molecules. Comparison of the two machine-learning methods shows that the inductive-logic-programming method displays a greater sensitivity than decision trees and successfully exploit background knowledge such as functional annotations and pathways of drug targets, thereby producing rich and expressive rules. All models and theories are available on a dedicated web site. Side effect profiles covering significant number of drugs have been extracted from a drug ×side-effect association table. Integration of background knowledge concerning both chemical and biological spaces has been combined with a relational learning method for discovering rules which explicitly

    To examine baseline psychological functioning and antiepileptic drug (AED) behavioral side effects in new onset epilepsy and determine, by age, whether baseline psychological functioning predicts AED behavioral side effects 1 month following AED initiation. A retrospective chart review was conducted between July 2011 and December 2014 that included youths with new onset epilepsy. As part of routine interdisciplinary care, caregivers completed the Behavior Assessment System for Children, 2nd Edition: Parent Rating Scale to report on baseline psychological functioning at the diagnostic visit and the Pediatric Epilepsy Side Effects Questionnaire to identify AED behavioral side effects at the 1-month follow-up clinic visit following AED initiation. Children (age = 2-11 years) and adolescents (age = 12-18 years) were examined separately. A total of 380 youths with new onset epilepsy (M age  = 8.9 ± 4.3 years; 83.4% Caucasian; 34.8% focal epilepsy, 41.1% generalized epilepsy, 23.7% unclassified epilepsy) were included. Seventy percent of youths had at-risk or clinically elevated baseline psychological symptoms. Children had significantly greater AED behavioral side effects (M = 25.08 ± 26.36) compared to adolescents (M = 12.36 ± 17.73), regardless of AED. Valproic acid demonstrated significantly greater behavioral side effects compared to all other AEDs, with the exception of levetiracetam. Higher hyperactivity/impulsivity at baseline significantly predicted higher AED behavioral side effects 1 month after AED initiation in both age groups. Younger children seem to be more prone to experience behavioral side effects, and these are likely to be higher if youths with epilepsy have baseline hyperactivity/impulsivity. Baseline psychological screening, specifically hyperactivity, can be used as a precision medicine tool for AED selection. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

    To gain insight into patients' medical decisions by exploring the content of laypeople's spontaneous mental associations with the term "side effect." An online cross-sectional survey asked 144 women aged 40-74, "What are the first three things you think of when you hear the words 'side effect?"' Data were analyzed using content analysis, chi-square, and Fisher's exact tests. 17 codes emerged and were grouped into 4 themes and a Miscellaneous category: Health Problems (70.8% of participants), Decision-Relevant Evaluations (52.8%), Negative Affect (30.6%), Practical Considerations (18.1%) and Miscellaneous (9.7%). The 4 most frequently identified codes were: Risk (36.1%), Health Problems-Specific Symptoms (35.4%), Health Problems-General Terms (32.6%), and Negative Affect-Strong (19.4%). Code and theme frequencies were generally similar across demographic groups (ps>0.05). The term "side effect" spontaneously elicited comments related to identifying health problems and expressing negative emotions. This might explain why the mere possibility of side effects triggers negative affect for people making medical decisions. Some respondents also mentioned decision-relevant evaluations and practical considerations in response to side effects. Addressing commonly-held associations and acknowledging negative affects provoked by side effects are first steps healthcare providers can take towards improving informed and shared patient decision making.

    Purpose: To evaluate early side effects in prostate cancer patients treated with image-guided conformation arc therapy (IGCAT) using a minimultileaf collimator and daily X-ray-assisted patient positioning. Methods and Materials: Between May 2000 and November 2004, 238 cT1-T3N0M0 tumors were treated with doses of 70 or 78 Gy. Seventy patients also received neoadjuvant or concurrent hormonal treatment. Median follow-up is 18 months (range, 4-55 months). Radiation Therapy Oncology Group and the European Organization for Research and Treatment of Cancer toxicity scoring system was used to evaluate early side effects. Results: Grade 1, 2, and >2 acute side effects occurred in 19, 6, and 0% (gastrointestinal) and 37, 16, and 0% (genitourinary) of the patients. No relation between radiation dose and early side effects was observed. Conclusion: Patients treated with image-guided conformation arc therapy experience a low rate of Grade 2 (i.e., requiring medication) early side effects. The definitive evaluation of late side effects and biochemical control requires further follow-up

  18. Cardiac Side-effects From Breast Cancer Radiotherapy.

    Breast cancer radiotherapy reduces the risk of cancer recurrence and death. However, it usually involves some radiation exposure of the heart and analyses of randomised trials have shown that it can increase the risk of heart disease. Estimates of the absolute risks of radiation-related heart disease are needed to help oncologists plan each individual woman's treatment. The risk for an individual woman varies according to her estimated cardiac radiation dose and her background risk of ischaemic heart disease in the absence of radiotherapy. When it is known, this risk can then be compared with the absolute benefit of the radiotherapy. At present, many UK cancer centres are already giving radiotherapy with mean heart doses of less than 3 Gy and for most women the benefits of the radiotherapy will probably far outweigh the risks. Technical approaches to minimising heart dose in breast cancer radiotherapy include optimisation of beam angles, use of multileaf collimator shielding, intensity-modulated radiotherapy, treatment in a prone position, treatment in deep inspiration (including the use of breath-hold and gating techniques), proton therapy and partial breast irradiation. The multileaf collimator is suitable for many women with upper pole left breast cancers, but for women with central or lower pole cancers, breath-holding techniques are now recommended in national UK guidelines. Ongoing work aims to identify ways of irradiating pan-regional lymph nodes that are effective, involve minimal exposure of organs at risk and are feasible to plan, deliver and verify. These will probably include wide tangent-based field-in-field intensity-modulated radiotherapy or arc radiotherapy techniques in combination with deep inspiratory breath-hold, and proton beam irradiation for women who have a high predicted heart dose from intensity-modulated radiotherapy.

    The photovoltaic properties of a series of low band-gap conjugated copolymers, in which alkyl side chains were substituted at various positions, were investigated using donor–acceptor (D–A) conjugated copolymers consisting of a cyclopentadithiophene derivative and dithienyl-benzothiadiazole. The base polymer, which has no alkyl side chains, yielded promising power conversion efficiency of 3.8%. Polymers with alkyl side chains, however, exhibited significantly decreased performance. In addition, the effects of processing additive became negligible. The results indicate that substituted side chains, which were introduced to improve solubility, critically affected the optical and electronic properties of D–A conjugated copolymers. Furthermore, the position of the side chain was also very important for controlling the morphological properties of the D–A conjugated copolymers. - Highlights: ► Effect of side chain position on solar cell performance was investigated. ► Polymer without alkyl chains yielded promising power conversion efficiency of 3.8%. ► Position of side chains critically affected the optical and electronic properties.

    Full Text Available In the article, the literature on the effects of TNFa-antagonists (etanercept, infliximab and adalimumab on the immune system is reviewed. These biologic agents are employed in chronic inflammatory diseases such as rheumatoid arthritis, seronegative spondyloarthritides, as well as psoriasis and Crohn’s disease. The differences of these drugs, testified by the different effects on the immune response, are discussed. These molecules exert their effect through cytokine inhibition, but they present striking differences since they can modulate macrophage activity, T cells apoptosis, leukocyte migration, and angiogenesis to a different degree. Some studies showed that these agents also affect the hypothalamo- pituitary-adrenal axis. The potential immunogenicity of these biologic agents is also discussed.

    We examined pregnant women's intention to obtain the seasonal influenza vaccine via a randomized controlled study examining the effects of immunization history, message exposure, and sociodemographic correlates. Pregnant women ages 18-50 participated in a randomized message framing study from September 2011 through May 2012. Venue-based sampling was used to recruit racial and ethnic minority women throughout Atlanta, Georgia. Key outcomes were evaluated using bivariate and multivariate analyses. History of influenza immunization was positively associated with intent to immunize during pregnancy [OR=2.31, 90%CI: (1.06, 5.00)]. Significant correlates of intention to immunize included perceived susceptibility to influenza during pregnancy [OR=3.8, 90% CI: (1.75, 8.36)] and vaccine efficacy [OR=10.53, 90% CI: (4.34, 25.50)]. Single message exposure did not influence a woman's intent to vaccinate. Prior immunization, perceived flu susceptibility and perceived vaccine effectiveness promoted immunization intent among this population of pregnant minority women. Vaccine efficacy and disease susceptibility are critical to promoting immunization among women with no history of seasonal influenza immunization, while those who received the vaccine are likely to do so again. These findings provide evidence for the promotion of repeated exposure to vaccine messages emphasizing vaccine efficacy, normative support, and susceptibility to influenza.

    Unexpected side effects of drugs are great concern in the drug development, and the identification of side effects is an important task. Recently, machine learning methods are proposed to predict the presence or absence of interested side effects for drugs, but it is difficult to make the accurate prediction for all of them. In this paper, we transform side effect profiles of drugs as their quantitative scores, by summing up their side effects with weights. The quantitative scores may measure the dangers of drugs, and thus help to compare the risk of different drugs. Here, we attempt to predict quantitative scores of drugs, namely the quantitative prediction. Specifically, we explore a variety of drug-related features and evaluate their discriminative powers for the quantitative prediction. Then, we consider several feature combination strategies (direct combination, average scoring ensemble combination) to integrate three informative features: chemical substructures, targets, and treatment indications. Finally, the average scoring ensemble model which produces the better performances is used as the final quantitative prediction model. Since weights for side effects are empirical values, we randomly generate different weights in the simulation experiments. The experimental results show that the quantitative method is robust to different weights, and produces satisfying results. Although other state-of-the-art methods cannot make the quantitative prediction directly, the prediction results can be transformed as the quantitative scores. By indirect comparison, the proposed method produces much better results than benchmark methods in the quantitative prediction. In conclusion, the proposed method is promising for the quantitative prediction of side effects, which may work cooperatively with existing state-of-the-art methods to reveal dangers of drugs.

    This review describes findings concerning persisting effects of A-bomb radiation on immune cells and their relation to diseases. Injuries in immune system are mainly the depression of cellular immunity mediated by T-lymphocytes, especially CD4 T-cells, and the elevation of humoral immunity by B-cells. These are conceivably the imbalance results in immune system of incomplete recovery of those T-cells after exposure and thymus retraction by aging and of consequently affecting the functional differentiation of CD4 T-cells to lower the cellular immunity and to elevate the humoral immunity. Lowered cellular immunity in the survivors can be related to their liver and cardiovascular diseases caused by infection and cancer caused by tumor antigens and oncoviruses. Thus immunological investigations of the survivors are revealing not only the effect of radiation on the immune system but also the correlation between immunity and diseases. (K.H.)

    Trans-generational immune priming is the transmission of enhanced immunity to offspring following a parental immune challenge. Although within-generation increased investment into immunity demonstrates clear costs on reproductive investment in a number of taxa, the potential for immune priming to impact on offspring reproductive investment has not been thoroughly investigated. We explored the reproductive costs of immune priming in a field cricket, Teleogryllus oceanicus. To assess the relative importance of maternal and paternal immune status, mothers and fathers were immune-challenged with live bacteria or a control solution and assigned to one of four treatments in which one parent, neither or both parents were immune-challenged. Families of offspring were reared to adulthood under a food-restricted diet, and approximately 10 offspring in each family were assayed for two measures of immunocompetence. We additionally quantified offspring reproductive investment using sperm viability for males and ovary mass for females. We demonstrate that parental immune challenge has significant consequences for the immunocompetence and, in turn, reproductive investment of their male offspring. A complex interaction between maternal and paternal immune status increased the antibacterial immune response of male offspring. This increased immune response was associated with a reduction in son's sperm viability, implicating a trans-generational resource trade-off between investment into immunocompetence and reproduction.

    Full Text Available Objective. The aim of the study was to investigate the possible protective qualities of resveratrol (RSV against the side effects of risperidone (RIS in an experimental model in rat kidneys with histologic and biochemical assessments. Materials and Methods. Experimental procedures were performed on 35 female Sprague Dawley rats. Rats were randomly divided into five groups: control, untreated rats (n=7 were in group 1; group 2 was given 2 mg/kg/day RIS (n=7; group 3 was treated with 2 mg/kg/day RIS and 20 mg/kg/day RSV (n=7; group 4 was treated with 2 mg/kg/day RIS and 40 mg/kg/day RSV (n=7; and group 5 was treated with 2 mg/kg/day RIS and 80 mg/kg/day RSV (n=7. All treatments were administered for two weeks by gavage. On treatment day 15, kidney tissues were removed for analysis. Results. The results showed that RSV treatment reduced weight gain induced by RIS. In addition, RSV increased the total antioxidant status (TAS and decreased serum creatinine (Cr, blood urea nitrogen (BUN, oxidative stress index (OSI, and total oxidant status (TOS levels significantly (p<0.05. Conclusion. This study revealed that treatment with RSV might protect kidney tissues against the side effects of RIS. RSV could be an effective course of therapy to enhance therapeutic efficacy.

  11. Muscle-related side-effects of statins: from mechanisms to evidence-based solutions.

    2015-06-01

    This article highlights the recent findings regarding statin-associated muscle side effects, including mechanisms and treatment as well as the need for more comprehensive clinical trials in statin myalgia. Statin myalgia is difficult to diagnose and treat, as major clinical trials have not routinely assessed muscle side-effects, there are few clinically relevant biomarkers and assessment tools for the symptoms, many apparent statin-related muscle symptoms may be nonspecific and related to other drugs or health conditions, and prevalence estimates vary widely. Data thus suggest that only 30-50% of patients with self-reported statin myalgia actually experience muscle pain on statins during blinded, placebo-controlled trials. In addition, evidence to date involving mechanisms underlying statin myalgia and its range of symptoms and presentations supports the hypothesis that there are multiple, interactive and potentially additive mechanisms underlying statin-associated muscle side-effects. There are likely multiple and interactive mechanisms underlying statin myalgia, and recent studies have produced equivocal data regarding prevalence of statin-associated muscle side-effects, contributing factors and effectiveness of common interventions. Therefore, more clinical trials on statin myalgia are critical to the field, as are systematic resources for quantifying, predicting and reporting statin-associated muscle side-effects.

    To study the effects of end-to-side anastomosis of initially-denatured nerves at different times. 60 male Wistar albino rats were used to fabricate animal models for the experiment on end-to-side anastomosis of peripheral nerves and 50 female Wistar albino rats were used to fabricate animal models for the experiment on the effect of FK506 on end-to-side anastomosis. Bilateral common peroneal nerve, tibialis anterior muscle electrophysiological and histological examinations, tibialis anterior muscle wet muscle weight determination, and motor end plate examination were performed 3 months after operation. All recovery rates of action potential, single muscle contraction force and tetanic contraction force of the FK506 experimental group are significantly higher than those of the control group and the sectional area of muscle fiber is also higher than that of the control group of normal saline. The best time for end-to-side anastomosis of nerves should be controlled within 2 weeks and the effect of end-to-side anastomosis of nerves will gradually become unsatisfactory. FK506 plays a role in promoting functional rehabilitation following nerve end-to-side anastomosis (Tab. 7, Fig. 4, Ref. 31).

    Benua, Leeper, and others (BEL) have advocated the estimation of radiation exposure to the blood to select a more rational maximum safe dose of radioiodine (dosimetry) to treat metastatic functioning well-differentiated thyroid carcinoma. After adopting the BEL dosimetry approach, we reviewed the immediate (during hospitalization) and intermediate (from discharge up to 3 mo) side effects after our initial 15 therapies in ten patients. The doses ranged from 51 mCi (1887 MBq) to 450 mCi (16.65 GBq). Immediate side effects were observed in 12/15 (80%), are described in detail, and were as follows: gastrointestinal 10/15, salivary 9/15, nonsalivary neck pain, swelling, etc. 2/15, pulmonary 0/15. Intermediate side effects were observed in 10/15 (67%), are described in detail, and were as follows: gastrointestinal 0/15, salivary 3/15, nonsalivary neck pain, swelling, etc. 3/15, nasal complaints 2/15, transient bone marrow suppression 9/10, pulmonary 0/15. No patient required blood transfusions or had complications secondary to reduced blood counts. All patient complaints resolved; however, several patients may have reduced baseline blood counts one year after therapy. No other long-term side effect has been noted but the mean follow-up has been only 15 mo. In our opinion, we have not observed any side effect to date which would contraindicate the continued use and evaluation of the BEL dosimetry approach

    Many medications used to manage multiple sclerosis (MS) affect oral health. This review aimed to identify the oral side-effects of the current drugs recommended in Australia to treat MS and make dental practitioners aware of the range of symptoms. The Australian Therapeutic Guidelines and the Australian Medicines Handbook were searched for medications used to treat MS. For each medication, the generic name, class, route of administration, dosage and drug company reported side-effects were extracted from the online Monthly Index of Medical Specialties (MIMs) database. Meyler's Side-effect of Drugs Encyclopaedia was used to identify any additional oral adverse reactions to medications used to treat MS. Fourteen drugs were identified for the treatment of MS progression and 13 drugs for the treatment of MS symptoms. For these medications, 18 oral side-effects were documented: xerostomia was the most common, followed by dysgeusia, dysphagia, mouth ulceration and sinusitis. Anticholinergic drugs caused xerostomia while immunosuppressants resulted in more infection-related side-effects. Dental practitioners should be aware of the range of symptoms likely to be reported by this population. Clinicians are encouraged to continue providing dental care for their patients who develop MS and refer complex cases to specialists. © 2017 Australian Dental Association.

    Narcolepsy is a disease in which there is diurnal excessive sleepiness with sleep attacks and a prevalence in the general population of 1/4000 individuals. Classically, it is characterized by cataplexy, sleep paralysis, hypnagogic hallucinations and fragmented sleep. The use of modafinil in the treatment of narcolepsy is the first option of treatment for diurnal excessive sleepiness. Although considered a safe drug for use in patients with narcolepsy, being utilized for more than 20 years, modafinil possesses a series of side effects, some of them still not fully researched or described. Side effects such as headache, nausea, anxiety, insomnia, lumbago, diarrhea, dyspepsia, rhinitis and vertigo are the most frequent. However, the clinical follow-up of patients under treatment with modafinil must be intensive and the side effects ought to be noted and evaluated. The under-response to treatment or the unexpected side effects must always be directed to differential diagnostics. The objective of this article is to describe an unexpected side effect of the use of modafinil in a patient with incorrect diagnosis of narcolepsy. PMID:26483900

    Evidence suggests that hypnosis is an effective intervention for reducing distress, pain and other side effects associated with cancer and its treatment. However, hypnosis has failed to be adopted into standard clinical practice. This study (n=115) investigated overall intentions to use hypnosis to control side effects of cancer and its treatment, as well as demographic predictors of such intentions among healthy volunteers. Results suggest that the vast majority of patients (89%) would be willing to use hypnosis to control side effects associated with cancer treatment. Mean intention levels did not differ by gender, ethnicity, education or age. These results indicate that in the general public, there is a willingness to consider the use of hypnosis, and that willingness is not determined by demographic factors. This broad acceptance of hypnosis argues for more widespread dissemination. PMID:21049742

    A double blind study was performed to examine the side-effects of Metrizamide (group 1) and of Jopamidol (group 2) in ascending cervical myelography. Both groups were compared to a control group (group 3) comprising patients who had undergone lumbar puncture only. EEG was taken of the patients in groups 1 and 2 before as well as 6 and 24 h after intervention. Side-effects were collected by means of a questionnaire. Response time, concentration, memory and mood were examined psychometrically. Training effects or defensive attitudes in the multiple test examinations were checked against another control group of patients (group 4) which had no myelographic nor lumbar-puncture-induced impairment. Statistical findings corroborated our clinical impression that side-effects occurred after Metrizamide administration at a more than simply random rate. (orig.) [de

    The optimization problem of the effective properties for magnetoelectric composites is considered. The effective properties are determined by the semi-analytical Mori-Tanaka approach. The generalized Eshelby tensor components are calculated numerically by using the Gauss quadrature method for the integral representation of the inclusion problem. The linear magnetoelectric constitutive equation is used. The effect of orientation of the electromagnetic materials components is taken into account. The optimization problem of the design is formulated and the artificial immune system is applied to solve it.

    Full Text Available The purpose of this study was to examine, first, the movement actions performed during two different small-sided games and, second, their effects on a series of field endurance and technical tests. Thirty-four young soccer players (age: 13 ± 0.9 yrs; body mass: 62.3 ± 15.1 kg; height: 1.65 ± 0.06 m participated in the study. Small-sided games included three-a-side (3 versus 3 players and six-a-side (6 versus 6 players games consisting of 10 bouts of 4 min duration with 3 min active recovery between bouts. Soccer player performance was evaluated using five field tests: a 30m sprint, b throw-in for distance, c Illinois Agility Test, d dribbling the ball and e horizontal jump before, in the middle and after the implementation of both game situations. Heart rate was monitored during the entire testing session. Each game was also filmed to measure soccer movements within the game. The ANOVA analysis indicated that the three-a- side games displayed significantly higher heart rate values compared with the six-a-side games (p < 0.05. The number of short passes, kicks, tackles, dribbles and scoring goals were significantly higher during the three-a-side compared with the six-a-side game condition (p < 0. 05 while players performed more long passes and headed the ball more often during the six-a-side (p < 0.05. After the three-a-side games, there was a significant decline in sprint and agility performance (p < 0.05, while after both game conditions significant alterations in the throw-in and the horizontal jump performance were observed (p < 0.05. The results of the present study indicated that three-a-side games provide higher stimulus for physical conditioning and technical improvement than six-a-side games and their use for training young soccer players is recommended

    People with epilepsy are at increased risk of accidents and injuries but, despite several studies on this subject, data regarding preventable causes are still contradictory. The aim of this study was to investigate the relationship between injuries, side effects of antiepileptic drugs (AEDs) and depression. Data from a consecutive sample of adult patients with epilepsy attending the outpatient clinics at St George's University Hospital in London were included. All patients were asked if they had had any injury since the last clinic appointment and completed the Liverpool Adverse Event Profile (LAEP) and Neurological Disorders Depression Inventory for Epilepsy. Among 407 patients (243 females, mean age 43.1 years), 71 (17.4%) reported injuries since the last appointment. A two-step cluster analysis revealed two clusters with the major cluster (53.5% of the injured group) showing a total score for LAEP ≥45, a positive Neurological Disorders Depression Inventory for Epilepsy screening and presence of AED polytherapy. A total score for LAEP ≥45 was the most important predictor. Antiepileptic drug treatment should be reviewed in patients reporting injuries in order to evaluate the potential contribution and burden of AED side effects. © 2017 EAN.

    A comprehensive analysis is performed to evaluate the effect of weight, height and body mass index (BMI) of occupants on side impact injuries at different body regions. The accident dataset for this study is based on the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) for accident year 2000-08. The mean BMI values for driver and front passenger are estimated from all types of crashes using NASS database, which clearly indicates that mean BMI has been increasing over the years in the USA. To study the effect of BMI in side impact injuries, BMI was split into three groups namely (1) thin (BMI30). For more clear identification of the effect of BMI in side impact injuries, a minimum gap of three BMI is set in between each adjacent BMI groups. Car model years from MY1995-1999 to MY2000-2008 are chosen in order to identify the degree of influence of older and newer generation of cars in side impact injuries. Impact locations particularly side-front (F), side-center (P) and side-distributed (Y) are chosen for this analysis. Direction of force (DOF) considered for both near side and far side occupants are 8 o'clock, 9 o'clock, 10 o'clock and 2 o'clock, 3 o'clock and 4 o'clock respectively. Age <60 years is also one of the constraints imposed on data selection to minimize the effect of bone strength on the occurrence of occupant injuries. AIS2+ and AIS3+ injury risk in all body regions have been plotted for the selected three BMI groups of occupant, delta-V 0-60kmph, two sets (old and new) of car model years. The analysis is carried with three approaches: (a) injury risk percentage based on simple graphical method with respect to a single variable, (b) injury distribution method where the injuries are marked on the respective anatomical locations and (c) logistic regression, a statistical method, considers all the related variables together. Lower extremity injury risk appears to be high for thin BMI group. It is found that BMI does not have much

    The pediatric Critical Illness Stress-induced Immune Suppression (CRISIS) trial compared the effectiveness of 2 nutraceutical supplementation strategies and found no difference in the development of nosocomial infection and sepsis in the overall population. We performed an exploratory post hoc analysis of interaction between nutraceutical treatments and host immune status related to the development of nosocomial infection/sepsis. Children from the CRISIS trial were analyzed according to 3 admission immune status categories marked by decreasing immune competence: immune competent without lymphopenia, immune competent with lymphopenia, and previously immunocompromised. The comparative effectiveness of the 2 treatments was analyzed for interaction with immune status category. There were 134 immune-competent children without lymphopenia, 79 previously immune-competent children with lymphopenia, and 27 immunocompromised children who received 1 of the 2 treatments. A significant interaction was found between treatment arms and immune status on the time to development of nosocomial infection and sepsis ( P patient characteristic.

    Antidepressant-induced sexual dysfunction adversely affects the quality of life of antidepressant users and reduces compliance with treatment. Animal models provide an instructive approach for examining potential sexual side effects of novel drugs. This review discusses the stability and reproducibility of our standardized test procedure that assesses the acute, subchronic and chronic effects of psychoactive compounds in a 30 minute mating test. In addition, we present an overview of the effects of several different (putative) antidepressants on male rat sexual behavior, as tested in our standardized test procedure. By comparing the effects of these mechanistically distinct antidepressants (paroxetine, venlafaxine, bupropion, buspirone, DOV 216,303 and S32006), this review discusses the putative mechanism underlying sexual side effects of antidepressants and their normalization. This review shows that sexual behavior is mainly inhibited by antidepressants that increase serotonin neurotransmission via blockade of serotonin transporters, while those that mainly increase the levels of dopamine and noradrenaline are devoid of sexual side effects. Those sexual disturbances cannot be normalized by simultaneously increasing noradrenaline neurotransmission, but are normalized by increasing both noradrenaline and dopamine neurotransmission. Therefore, it is hypothesized that the sexual side effects of selective serotonin reuptake inhibitors may be mediated by their inhibitory effects on dopamine signaling in sex brain circuits. Clinical development of novel antidepressants should therefore focus on compounds that simultaneously increase both serotonin and dopamine signaling. © 2013 Elsevier Inc. All rights reserved.

    2010-01-01

    Side effects of anabolic steroids with relevance in forensic medicine are mainly due to life-threatening health risks with potential fatal outcome and cases of uncertain limitations of criminal liability after steroid administration. Both problems are typically associated with long-term abuse and excessive overdose of anabolic steroids. Side effects may be due to direct genomic or nongenomic activities (myotrophic, hepatotoxic), can result from down-regulation of endogenous biosynthesis (antiandrogenic) or be indirect consequence of steroid biotransformation (estrogenic).Logically, there are no systematic clinical studies available and the number of causally determined fatalities is fairly limited. The following compilation reviews typical abundant observations in cases where nonnatural deaths (mostly liver failure and sudden cardiac death) were concurrent with steroid abuse. Moreover, frequent associations between structural characteristics and typical side effects are summarized.

    Full Text Available Attention deficit hyperactivity disorder (ADHD is one of the most common neurobehavioral disorders of childhood and adolescence. Classically, stimulants have been used in the treatment of this condition. Atomoxetine (Strattera; Eli Lilly and Company is a selective norepinephrine reuptake inhibitor (SNRI, one of the first medications in the nonstimulant class of medications that has been approved by the FDA for the treatment of ADHD. Atomoxetine is a phenoxypropylamine derivative and is structurally related to the antidepressant fluoxetine. The common side effects reported with the use of atomoxetine include mainly GI disturbances. Cardiovascular side effects are less commonly reported. The increase in the noradrenergic tone may explain some of the side effects noted with the use of this medication. Here, we present a case of a patient who presented with syncope, orthostatic hypotension, and tachycardia and discuss the various clinical implications based on the pharmacokinetics and pharmacodynamics of the drug.

    2014-05-15

    Most patients treated with curative intent for colorectal cancer (CRC) are included in a follow-up program involving periodic evaluations. The survival benefits of a follow-up program are well delineated, and previous meta-analyses have suggested an overall survival improvement of 5%-10% by intensive follow-up. However, in a recent randomized trial, there was no survival benefit when a minimal vs an intensive follow-up program was compared. Less is known about the potential side effects of follow-up. Well-known side effects of preventive programs are those of somatic complications caused by testing, negative psychological consequences of follow-up itself, and the downstream impact of false positive or false negative tests. Accordingly, the potential survival benefits of CRC follow-up must be weighed against these potential negatives. The present review compares the benefits and side effects of CRC follow-up, and we propose future areas for research.

    Preceding anaesthesia 750 randomised patients, sub-divided into 5 different age groups, were given 500 ml of a standard plasma-substitute at a flow rate of 25-30 ml/min. There was direct correlation (p=0.1%) of the frequency of side-effects to the substance used; none, however, to the age or general surgical risk. Side-effects were observed in 21.3% with derivates of gelatin as compared to 3.7% with Macrodex and Plasmasteril combined. The rate of more serious anaphylactoid reactions was 6% with Haemaccel, 1.3% with Gelifundol-S, 0.67% with Macrodex and less than 0.67% with Neo-Plasmagel. The study reveals that serious side-effects may be expected in orthopaedictic patients after application of plasma substitutes. As a prophylactic procedure for those patients we recommend, therefore, the application of these substances only after careful consideration of the indications for their use.

    Full Text Available omorbid psychiatric disorders, frequent hospitalization, multiple outpatient treatment, prior history of hypertension, obesity and lipid dysregulation are associated with higher risk of metabolic syndrome in children. Side effects of antipsychotic drugs and their management have recently become a major subject of research due to enhanced antipsychotic drug usage in child and adolescents. Prevention strategies are usually preferred to secondary or tertiary strategies in the management of metabolic syndrome associated with antipsychotic drugs. Clinicians should present multidisciplinary approach to endocrine and metabolic side effects due to antipsychotic use in pediatric patient groups and avoid multiple drug use in such patients. In this paper, we briefly reviewed metabolic side effects of second generation antipsychotic drugs in child and adolescent population, possible mechanisms of susceptibility to metabolic syndrome and pharmacological and non pharmacological treatment approach to prevention of weight gain.

    Full Text Available Background: Clozapine is the antipsychotic of choice for treatment-resistant schizophrenia and has minimal risk for extrapyramidal symptoms. Therapeutic benefits, however, are accompanied by a myriad of cardiometabolic side-effects. The specific reasons for clozapine's high propensity to cause adverse cardiometabolic events remain unknown, but it is believed that autonomic dysfunction may play a role in many of these.Objective: This systematic review summarizes the literature on autonomic dysfunction and related cardiovascular side effects associated with clozapine treatment.Method: A search of the EMBASE, MEDLINE, and EBM Cochrane databases was conducted using the search terms antipsychotic agents, antipsychotic drug*, antipsychotic*, schizophrenia, schizophren*, psychos*, psychotic*, mental ill*, mental disorder*, neuroleptic*, cardiovascular*, cardiovascular diseases, clozapine*, clozaril*, autonomic*, sympathetic*, catecholamine*, norepinephrine, noradrenaline, epinephrine, adrenaline.Results: The search yielded 37 studies that were reviewed, of which only 16 studies have used interventions to manage cardiovascular side effects. Side effects reported in the studies include myocarditis, orthostatic hypotension and tachycardia. These were attributed to sympathetic hyperactivity, decreased vagal contribution, blockade of cholinergic and adrenergic receptors, reduced heart rate variability and elevated catecholamines with clozapine use. Autonomic neuropathy was identified by monitoring blood pressure and heart rate changes in response to stimuli and by spectral analysis of heart rate variability. Metoprolol, lorazepam, atenolol, propranolol, amlodipine, vasopressin and norepinephrine infusion were used to treat tachycardia and fluctuations in blood pressure, yet results were limited to case reports.Conclusion: The results indicate there is a lack of clinical studies investigating autonomic dysfunction and a limited use of interventions to manage

For example, a German campaign raised awareness that infection is unlikely in low-risk day-to-day interactions. Research has yet to show that there are no harmful side effects. This is essential because such messages promote a less threatening picture of HIV and thus may unintentionally increase complacency. We tested the possible side effects on the willingness to have sex without condoms. An experiment was conducted in which participants were exposed to anti-stigma messages or not. Anti-stigma messages did not elicit an increase in the willingness to have sex without condoms.

    Full Text Available The research goal is to study the immune effects in patients with external genital endometriosis. 126 patients with external genital endometriosis ages 22-44 years have been examined. CD3+, CD4+, CD8+, CD16+, CD19+, CD25+, immunoglobulin A, M, G are defined in peripheral blood and peritoneal liquid. Method of cytoflowmetry and radial immunodiffusion by Manchini has been used. Statistical processing of results has been spent by means of a package of the statistical program «Statgraphics», STSC (USA. Reliability of variability has been estimated by means of calculation of nonparametric criterion by Uilkokson — Mann — Uitni. Depression of cellular and increase of humoral immunity (IgG and IgA in peritoneal liquid have been revealed. Degree of expressiveness of immunity has been depended on presence of inflammatory diseases, duration of disease, localization of the pathology center. In peritoneal liquid the total amount of T-lymphocytes, CD4+ cells and CD8+ lymphocytes has been increased in patients with of external genital endometriosis of lll-IV degree. The immunoregulatory index has been also increased. These results have confirmed the presence of inflammatory process in peritoneal cavity

    In previous studies, the authors have shown that hyperthermia can enhance antibody-complement chytotoxicity of hamster and human tumor cells. Moreover, whole body microwave exposure of hamsters resulted in activation of peritoneal macrophages to a viricidal state and transient suppression of natural killer (NK) cell activity. In this study, the authors compare the effects of whole body heating by microwaves or by an environmental chamber (hot air) on the hamster immune system. Microwave exposure (25mW/cm/sup 2/; 1 hr) caused viricidal activation of peritoneal macrophages which resulted in restriction of vaccinia and vesicular stomatitis virs (VSV) growth. However, heating in an environmental chamber (41 0 C; 1 hr) did not activate macrophages to a viricidal state. Both microwave and hot air hyperthermia caused significant augmentation of antibody producing spleen cell response to sheep red blood cells (SRBC), using the Jerne hymolytic plaque assay, four days post exposure and immunization with SRBC. Natural killer spleen cell cytotoxicity was suppressed by microwave and hot air hyperthermia showing that NK lymphocytes are extremely sensitive to changes in temperature. These alterations in cellular immune response due to hyperthermia could be of significance in treatment of tumors and viral infections

    Vascular malformations (VM) are congenital lesions that can be debilitating and cause significant aesthetic and functional limitations. The chemotherapeutic agent bleomycin has been utilized as a sclerosant, directly injected percutaneously into the VM. Unfortunately, little is known about the benefits and short-term side effects of bleomycin with intralesional injections. An IRB approved, retrospective chart review was performed on patients with VM who had been treated with intralesional bleomycin. Data included type of VM, number of treatments, total bleomycin dose per m², and adverse effects. A questionnaire was administered to available patients to assess subjective outcomes and side effects. Forty-six patients were treated with 141 procedures of bleomycin sclerotherapy for VM. Patient ages ranged from 1 to 20 years (median age 10 years). The median cumulative bleomycin dose was 16.3 units/m²/person (range of 1.7-97.0 units/m²/person). Sixty-three percent of patients were reached for a questionnaire to assess short-term side effects. Ninety percent of patients surveyed were satisfied to very satisfied with the results from the procedure. About 24% of patients experienced transient nausea, vomiting and/or local hyperpigmentation. Bleomycin sclerotherapy can be an effective treatment of VM with repeat exposure with minor risk of short-term side effects, however, long-term risks are of great concern. Further studies are required to assess systemic absorption and long-term risks. © 2018 Wiley Periodicals, Inc.

    This paper describes the evaluation of aerodynamic flow effects on side mirror geometry for a passenger car using ANSYS Fluent CFD simulation software. Results from analysis of pressure coefficient on side view mirror designs is evaluated to analyse the unsteady forces that cause fluctuations to mirror surface and image blurring. The fluctuation also causes drag forces that increase the overall drag coefficient, with an assumption resulting in higher fuel consumption and emission. Three features of side view mirror design were investigated with two input velocity parameters of 17 m/s and 33 m/s. Results indicate that the half-sphere design shows the most effective design with less pressure coefficient fluctuation and drag coefficient.

    An analysis is presented of physical phenomena occurring during secondary-side feed-and-bleed, which is being considered as an accident management procedure for pressurized water reactors. Problem areas related to the reliability of this procedure are identified and discussed. Secondary-side feed-and-bleed, as examined in the LOBI (which is the Light Water Reactor Off-Normal Behavior Investigation) integral system test facility, was not successful because of a delay in the secondary-side heat removal caused by the release of stored heat from the steam generator downcomer wall. Countercurrent flow limiting in the hot leg was another major phenomenon that can influence the effectiveness of this procedure. The discussion of the experimental results is complemented by relevant calculations by RELAP5/MOD3. In general, it was found that the effectiveness of the feed-and-bleed procedure is maximized if the number of steam generators used to implement it is reduced

  3. Do the emotional side-effects of hormonal contraceptives come from pharmacologic or psychological mechanisms?

    Hormonal preparations have become one of the most popular methods used for controlling fertility. The literature over the last 40 years continues to reveal how their numerous side effects negatively impact many users and even society at large. Three large cohort trials were the first to demonstrate, on a grand scale, certain emotional and behavioral associations with contraceptive use. Current contraceptive use was associated with an increase rate in depression, divorce, tranquilizer use, sexual dysfunction, and suicide and other violent and accidental deaths. Despite the advent of more "user friendly" contraceptives, the discontinuation rate secondary to side effects has changed little through the years. While in rare cases hormonal preparations can be deadly to the user, there is substantial evidence that their negative effect issues more from their emotional and behavioral properties. This paper reviews the results of over seven studies which further characterize these prominent associations, particularly with hormonal contraception, in an attempt to demonstrate their association with the intrinsic pharmacologic properties of hormonal preparations. Hormonal contraceptive users, in contrast with non users, were found to have higher rates of depression, anxiety, fatigue, neurotic symptoms, sexual disturbances, compulsion, anger, and negative menstrual effects. The question of whether the association of these maladies is directly due to the effect of taking exogenous hormones versus the psychological impact of the contraceptive behavior itself had yet to be studied. Seven small randomized-controlled trials were found in a review of the literature which studied this hypothesis in a direct way. They do not support the origination of these side effects being from the pharmacological properties of hormones. No association was found between hormone levels and emotional functioning in females.

    Opioids cause gastrointestinal (GI) symptoms such as nausea, vomiting, pain, and (in 40 percent) constipation that diminish patients' quality of life. Outside traditional surveys, little is known about the opioid-induced constipation (OIC) patient experience and its impact on pain management. The purpose of this study was to use data from social media platforms to qualitatively examine patient beliefs about OIC and other prominent GI side effects, their impact on effective pain management and doctor-patient interaction. The authors collected Tweets from March 25 to July 31, 2014, and e-forum posts from health-related social networking sites regardless of timestamp. The authors identified specific keywords related to opioids and GI side effects to locate relevant content in the dataset, which was then manually coded using ATLAS.ti software. The authors examined 2,519,868 Tweets and more than 1.8 billion e-forum posts, of which, 88,586 Tweets and 9,767 posts satisfied the search criteria. Three thousand three individuals experienced opioidinduced GI side effects, mostly related to phenanthrenes (n = 1,589), and 1,274 (42.4 percent) individuals described constipation. Over-the-counter medications and nonevidence-based natural approaches were most commonly used to alleviate constipation. Many individuals questioned, rotated, reduced, or stopped their opioid treatments as a result of their GI side effects. Investigation of social media reveals a struggle to balance pain management with opioid-induced GI side effects, especially constipation. Individuals are often unprepared to treat OIC, to modify opioid regiments without medical advice, and to resort to using natural remedies and treatments lacking scientific evidence of effectiveness. These results identify opportunities to improve physician-patient communication and explore effective treatment alternatives.

  5. Effect of oral administration of Lactobacillus paracasei L9 on mouse systemic immunity and the immune response in the intestine

    2016-01-01

    Full Text Available A probiotic strain Lactobacillus paracasei L9,which was isolated from human intestine, was investigated for its immunomodulatory activity in vivo. Results showed that L9 improved systemic immunity by enhancing the phagocytic activity of peritoneal macrophages, the proliferation ratio of splenocytes, the IgG level in the serum and the level of IgA in the mucosa. Further, L9induced theTh1-polarized immune response by elevating the IFN-γ/IL-4 ratio in the mucosa. This effect was confirmed by the enhanced IL-12-inducing activity of macrophages after in vitro stimulation of L9. Also detected was increased expression of TLR-2mRNA in the mucosa. We predict that L9 could enhance innate immunity by activating TLR-2 in the mucosa, and enhance acquired immunity by promoting Th1 polarization through induced production of IL-12 by macrophages.

  6. Exploring the Process of Conveying Information about Side Effects: A Qualitative Study among Pharmacists

    Full Text Available This study explored how a sample of Australian pharmacists would convey information about the side effects of a medicine, if they were to counsel a patient. A qualitative method was selected and written responses to a case-based scenario were analysed using inductive thematic analysis. The grounded theory approach elicited a fluid and dynamic model for side effect counselling. The study identified strategies for counselling, such as encouraging adherence through emphasising the benefits of the medication, referral to the prescriber, and providing empathy and reassurance to ease anxiety and address concerns. Pharmacists acknowledged the potential for risk, although only a minority used numerical descriptors. The final themes or outcomes were that pharmacists aim to allay fears, minimise harm and promote medication use when counselling about side effects. Professional empathy, the acknowledgment of patient concerns, and the importance of providing tailored information to promote medication adherence, emerged as features of the quality use of medicines. This study contributes to existing literature by identifying the role of allaying patients’ fears when conveying side effect information. It also describes a process to convey tailored information. Implications for practice include the importance of effective use of communication strategies to encourage adherence, as the appropriate use of medication can lead to positive health outcomes.

    relieving distressing symptoms and managing the side effects of analgesics are essential in order to improve quality of life and functional capacity in chronic non-cancer pain patients. A quick, reliable and valid tool for assessing symptoms and side effects is needed in order to optimize treatment. We aimed to investigate the symptoms reported by chronic non-cancer pain patients after open-ended questioning vs. a systematic assessment using a list of symptoms, and to assess whether the patients could distinguish between the symptoms and the side effects induced by analgesics. patients treated with either opioids and/or adjuvant analgesics were asked to report their symptoms spontaneously, followed by a 41-item investigator-developed symptom checklist. A control group also filled in the checklist. a total of 62 patients and 64 controls participated in the study. The numbers of symptoms reported by the patients (9.9 ± 5.9) were significantly higher than those reported by the controls (3.2 ± 3.9) (Pside effects due to analgesics was: (1) Dry mouth (42%); (2) Sweating (34%); (3) Weight gain (29%); (4) Memory deficits (24%); (5) Fatigue (19%); and (6) Concentration deficits (19%). the number of symptoms reported using systematic assessment was eightfold higher than those reported voluntarily. Fatigue, cognitive dysfunction, dry mouth, sweating and weight gain were the most frequently reported. The patients reported the side effects of their analgesics to contribute substantially to the reported symptoms. 2010 The Acta Anaesthesiologica Scandinavica Foundation.

    We measured cognitive side effects from bitemporal electroconvulsive therapy (ECT) using stimuli of 0.5 msec pulse width 900 milliamperes (mA). Mini-Mental State Exam (MMSE) and 21-item Hamilton Rating Scale for Depression (HRSD-21) were rated within 36 hours before and 36 hours after a series of 6 bitemporal ECT sessions on 15 patients age ≥45. MMSE remained high after ECT (pre-ECT mean 29, standard deviation [SD] 1.60, post-ECT mean 28.53, SD 1.36) with no significant change. The mean HRSD-21 fell from 27.5 to 16.3. Post-ECT MMSE was significantly and markedly higher than in previous studies of bitemporal ECT; all had used ECT stimuli of pulse width at least 1 msec. With stimuli of 0.5 msec pulse width and 900 mA, 6 bitemporal ECTs did not decrease MMSE score. This result leaves no opportunity for further decrease in basic cognitive side effects, and complements published reports of stronger physiological effects with stimuli of 0.5 msec pulse width and 900 mA. ECT stimuli of 0.5 msec pulse width and 900 mA are more desirable than wider pulse widths. Six bitemporal ECT sessions using these stimuli generally will not have more cognitive side effects than treatments with other placements, allowing maintenance of full efficacy with clinically insubstantial side effects.

    Full Text Available Introduction: Acne vulgaris is an inflammatory disease of pilosebaceous folicles. Tretinoin is used as one of the topical treatments for acne vulgaris. It has different cutaneous side effects such as erythema, scaling, irritation and photosensitivity. The aim of this study was to evaluate the efficacy of oral Vitamine E in preventing the cutaneous side effects of topical tretinoin in acne patients.
    Methods: A clinical trial was performed in AI-Zahra Hospital in Isfahan for six months in 2000. 80 patients with mild to moderate facial acne were randomized into 2 groups. Group 1 (controls received topical solution of tretinoin 0.05 percent nightly and group 2 (cases received daily oral 100mg of Vit. E in addition. All patients were followed at 1, 4 and 6 weeks after initiation of treatment. Children under 12 years old, pregnant or lactating women were excluded.
    Results: At the end of one week, no cutaneous side effects were observed in 25 percent (10 of group 1 and 15 percent (6 of group 2 (P > 0.05. At the end of 4 weeks, 25 percent (10 of group 1 and 60 percent (24 of group 2 were without any cutaneous complications, while at the end of 6 weeks, 35 percent (14 of group 1 in comparison to 75 percent (30 of group 2 were free of any cutaneous side effects (P < 0.05. The most common side effect in both groups was exfoliation.
    Discussion: Daily oral 100 mg of Vit. E has been effective in preventing cutaneous complications of topical tretinoin in acne management, but there is a delay of one week in its onset of action. Meanwhile, Vitamine E is a safe modality with no undesirable effects in acne patients.

    The capacity of immune cells obtained from the major lymphoid compartments to protect C58 mice from transplanted line Ib leukemia, and from an age-dependent autoimmune CNS disease (immune polioencephalomyelitis = IPE) elicited by immunizing old C58 mice with inactivated Ib cells was quantified. Cells used for comparative adoptive protection tests were harvested from the major lymphoid compartments 14 to 15 days after young C58 mice were immunized with inactivated Ib cell preparations. Regression curves were plotted from survival data and the log 10 PD 50 values were determined. Immune spleen (ISC) and peritoneal cells (IPEC) were significantly more protective against transplanted Ib cells than immune lymph node (ILNC), thymic (ITC), and marrow cells (IMC). In contrast, IPEC and IMC were not protective against IPE and ITC were only marginally protective. ILNC afforded significant protection to transplantable leukemia but were only marginally protective to IPE. When ISC were treated with anti-thy 1.2 serum and complement, protection against transplanted leukemia and IPE was reduced > 99%. When donors of immune lymphoid cells were treated with 12.5 mg of cortisone acetate daily for 2 days before lymphoid cells were harvested, protection against transplanted Ib cells by ISC was reduced by approximately 90% whereas protection against IPE was totally eliminated. Considered together, these results indicate that the protective mechanisms to transplantable leukemia and IPE differ significantly in the same indicator mouse strain

    Full Text Available Tuberculosis infection, disease and mortality are all less common at high than low altitude and ascent to high altitude was historically recommended for treatment. The immunological and mycobacterial mechanisms underlying the association between altitude and tuberculosis are unclear. We studied the effects of altitude on mycobacteria and antimycobacterial immunity.Antimycobacterial immunity was assayed in 15 healthy adults residing at low altitude before and after they ascended to 3400 meters; and in 47 long-term high-altitude residents. Antimycobacterial immunity was assessed as the extent to which participants' whole blood supported or restricted growth of genetically modified luminescent Bacille Calmette-Guérin (BCG mycobacteria during 96 hours incubation. We developed a simplified whole blood assay that could be used by a technician in a low-technology setting. We used this to compare mycobacterial growth in participants' whole blood versus positive-control culture broth and versus negative-control plasma.Measurements of mycobacterial luminescence predicted the number of mycobacterial colonies cultured six weeks later. At low altitude, mycobacteria grew in blood at similar rates to positive-control culture broth whereas ascent to high altitude was associated with restriction (p ≤ 0.002 of mycobacterial growth to be 4-times less than in culture broth. At low altitude, mycobacteria grew in blood 25-times more than negative-control plasma whereas ascent to high altitude was associated with restriction (p ≤ 0.01 of mycobacterial growth to be only 6-times more than in plasma. There was no evidence of differences in antimycobacterial immunity at high altitude between people who had recently ascended to high altitude versus long-term high-altitude residents.An assay of luminescent mycobacterial growth in whole blood was adapted and found to be feasible in low-resource settings. This demonstrated that ascent to or residence at high altitude was

    Drug therapy is the mainstay of treatment for overactive bladder (OAB), but antimuscarinic agents possess side-effects. These side-effects decrease the patients' quality of life. We therefore assessed the impact of side-effects on health-related quality of life (HR-QoL) through an analysis of EQ-5D questionnaire. This study was designed to investigate the patients' satisfaction by quality weight of health status as affected by the side-effects of OAB medications. Patients who had OAB symptoms lasting longer than 3 months and have experienced side-effects after any antimuscarinic treatments filled in the EQ-5D questionnaire. The enrolled patients had two EQ-5D questionnaires for two different health statuses, i.e., presence or absence of side-effects. Quality weight was calculated using the ED-5D health status score with Korean tariff. One hundred patients were enrolled and completed the HR-QoL questionnaire. The most prevalent side-effect was dry mouth (61%) and 28% patients had dry mouth and constipation concurrently. Most of the patients with side-effects tried to endure and overcome these side-effects (79%), but 10% desired a change in medication, and 6% stopped medication altogether. The quality weight of EQ-5D without side-effects was 0.863, while the quality weight with side-effects was 0.666 (P effects and 57 in those with side-effects, supporting the results of quality weight assessment. Overactive bladder patients may enjoy a better quality of life if side-effects associated with antimuscarinic therapy are fewer. © 2016 John Wiley & Sons Australia, Ltd.

    Privacy preserving data mining (PPDM) is an emerging research problem that has become critical in the last decades. PPDM consists of hiding sensitive information to ensure that it cannot be discovered by data mining algorithms. Several PPDM algorithms have been developed. Most of them are designed for hiding sensitive frequent itemsets or association rules. Hiding sensitive information in a database can have several side effects such as hiding other non-sensitive information and introducing redundant information. Finding the set of itemsets or transactions to be sanitised that minimises side effects is an NP-hard problem. In this paper, a genetic algorithm (GA) using transaction deletion is designed to hide sensitive high-utility itemsets for PPUM. A flexible fitness function with three adjustable weights is used to evaluate the goodness of each chromosome for hiding sensitive high-utility itemsets. To speed up the evolution process, the pre-large concept is adopted in the designed algorithm. It reduces the number of database scans required for verifying the goodness of an evaluated chromosome. Substantial experiments are conducted to compare the performance of the designed GA approach (with/without the pre-large concept), with a GA-based approach relying on transaction insertion and a non-evolutionary algorithm, in terms of execution time, side effects, database integrity and utility integrity. Results demonstrate that the proposed algorithm hides sensitive high-utility itemsets with fewer side effects than previous studies, while preserving high database and utility integrity.

    Full Text Available Abstract Background This study is part of a nationwide evaluation of complementary medicine in Switzerland (Programme Evaluation of Complementary Medicine PEK and was funded by the Swiss Federal Office of Public Health. The main objective of this study is to investigate patient satisfaction and perception of side effects in homeopathy compared with conventional care in a primary care setting. Methods We examined data from two cross-sectional studies conducted in 2002–2003. The first study was a physician questionnaire assessing structural characteristics of practices. The second study was conducted on four given days during a 12-month period in 2002/2003 using a physician and patient questionnaire at consultation and a patient questionnaire mailed to the patient one month later (including Europep questionnaire. The participating physicians were all trained and licensed in conventional medicine. An additional qualification was required for medical doctors providing homeopathy (membership in the Swiss association of homeopathic physicians SVHA. Results A total of 6778 adult patients received the questionnaire and 3126 responded (46.1%. Statistically significant differences were found with respect to health status (higher percentage of chronic and severe conditions in the homeopathic group, perception of side effects (higher percentage of reported side effects in the conventional group and patient satisfaction (higher percentage of satisfied patients in the homeopathic group.

    To analyse pharmacy customers' knowledge and information sources about side effects of medicines they purchased and factors associated with this knowledge. Cross-sectional survey and semi-structured interviews with customers of 52 randomly selected community pharmacies in Morelos state, Mexico. Customers were included if they were older than 18 years, bought at least one drug either with or without medical prescription, and agreed to take part in the survey. Data were analysed using a multinomial logistic regression model. A total of 1445 customers buying 1946 drugs were surveyed (age 42.9 +/- 15.7 years, 56.9% female); 627 (59%) of 1055 customers who purchased prescription-only medicines (POM) did so without a prescription. Of all customers interviewed, 172 (11.9%) affirmed that the bought medicine(s) could cause harm. Only half of those (87 or 6%) were able to identify correctly at least one side effect of the purchased medicines. The majority received the information about side effects from a physician. Customers in semirural areas knew less about side effects (odds ratio: 0.26; 95% CI: 0.11-0.61; P = 0.00); whereas customers buying medicines for chronic pain, hypertension or diabetes knew more (odds ratio 2.63; 95% CI: 1.44-4.80; P = 0.00). The overall majority of customers did not know that medicines they bought could be harmful. This is particularly alarming because they frequently used POM without consulting a physician.

    2003-01-01

    Atypical antipsychotics generally have milder side-effects than conventional antipsychotics, but also differ among themselves in this respect. This study aimed to compare the impact of different side-effect profiles of individual atypical antipsychotics on non-compliance, relapse and cost in schizophrenia. A state-transition model was built using literature data supplemented by expert opinion. The model found that quetiapine and ziprasidone were similar in estimated non-compliance and relapse rates. Olanzapine and risperidone had higher estimated non-compliance and relapse rates, and incremental, 1-year, per-patient direct costs, using US-based cost data, of approximately $530 (95% confidence interval [CI] approximately $275, $800), and approximately $485 (95% CI approximately $235, $800), respectively, compared with quetiapine. Incremental costs attributable to different side-effect profiles were highly significant. This study shows that differing side-effect profiles of the newer antipsychotic agents are likely to lead to different compliance rates, and consequent variation in relapse rates. The cost implications of these heterogenous clinical outcomes are substantial.

    2014-01-01

    Why do things go wrong? Why, despite all the planning and care in the world, do things go from bad to worse? This book argues that it is because we are like the ants. Just as ants create an anthill without being aware of it, unintended side effects of human activity create all manner of social trends and crises. The book traces the way these trends emerge and the role they play in some of the major issues of our time. One of the greatest challenges today is the complexity of our social and economic systems. Every action has side effects that people often ignore or fail to see. The book examines the ways in which limitations in our thinking and behaviour lead to unintended side effects. It looks at the role played by complex networks of interactions. Finally, it looks at the way side effects of new technologies, especially computers and communication, have created an Information Revolution, the full repercussions of which are yet to be seen. In our race to create new technologies and sustain indefinite economi...

    Older patients can be especially susceptible to antipsychotic-induced side effects, and the pharmacodynamic mechanism underlying this phenomenon remains unclear. We hypothesized that age-related epigenetic alterations lead to decreased expression and functionality of the dopamine D2 receptor (D2R), contributing to this susceptibility. In this study, we treated young (2-3 months old) and aged (22-24 months old) C57BL/6 mice with the D2R antagonist haloperidol (HAL) once a day for 14 days to evaluate HAL-induced motor side effects. In addition, we pretreated separate groups of young and aged mice with histone deacetylase (HDAC) inhibitors valproic acid (VPA) or entinostat (MS-275) and then administered HAL. Our results show that the motor side effects of HAL are exaggerated in aged mice as compared to young mice and that HDAC inhibitors are able to reverse the severity of these deficits. HAL-induced motor deficits in aged mice are associated with an age- and drug-dependent decrease in striatal D2R protein levels and functionality. Further, histone acetylation was reduced while histone tri-methylation was increased at specific lysine residues of H3 and H4 within the Drd2 promoter in the striatum of aged mice. HDAC inhibitors, particularly VPA, restored striatal D2R protein levels and functionality and reversed age- and drug-related histone modifications at the Drd2 promoter. These results suggest that epigenetic changes at the striatal Drd2 promoter drive age-related increases in antipsychotic side effect susceptibility, and HDAC inhibitors may be an effective adjunct treatment strategy to reduce side effects in aged populations.

    Androgen deprivation therapy (ADT) is a common treatment for prostate cancer with numerous side effects. We assess primary care physicians' (PCPs) knowledge of ADT side effects and their interest in increasing their knowledge in this area. A list of active Canadian PCPs was obtained using the Canadian Medical Directory. A cross-sectional survey was distributed to 600 randomly selected physicians. We collected PCPs' demographic information, experience with ADT management, knowledge regarding ADT side effects and desired sources for obtaining knowledge on ADT management. In total, we received 103 completed questionnaires. Of these, 89% of PCPs had patients on ADT. One-third of respondents prescribed ADT and over half of them administered ADT annually. Thirty-eight percent felt their knowledge of ADT side effects was inadequate and 50% felt uncomfortable counselling patients on ADT. Many PCPs were less familiar with the incidence of functional side effects of ADT (i.e., hot flashes, fatigue and erectile dysfunction) compared to life-threatening side effects (i.e., cardiovascular events, metabolic syndrome, fractures). In terms of increasing their knowledge of ADT side effects, 82% of PCPs would use educational resources if they were available (52% and 32% preferred continued medical education [CME] events and educational pamphlets, respectively). PCPs play an important role in managing ADT side effects. There is poor awareness of the prevalence of ADT side effects, and many are uncomfortable in managing these side effects. These areas may be addressed through CME programs and educational pamphlets.

    Ciguatoxins (CTXs) and brevetoxins (PbTxs) are phycotoxins that can accumulate along the marine food chain and thus cause seafood poisoning in humans, namely "ciguatera fish poisoning" (CFP) and "neurotoxic shellfish poisoning" (NSP), respectively. CFP is characterized by early gastrointestinal symptoms and typical sensory disorders (paraesthesia, pain, pruritus and cold dysaesthesia), which can persist several weeks and, in some cases, several months or years. NSP is considered a mild form of CFP with similar but less severe symptoms. After inhaled exposure, PbTxs can also cause respiratory tract irritation in healthy subjects and asthma exacerbations in predisposed subjects, whose respiratory functions may be disrupted for several days following PbTx inhalation. Mechanistically, it is well established that CTX- or PbTx-induced disturbances are primarily mainly due to voltage-gated sodium channel activation in sensory and motor peripheral nervous system. However, little is known about the pathophysiology or a potential individual susceptibility to long lasting effects of CFP/NSP. In addition to their action on the nervous system, PbTxs and CTXs were also shown to exert effects on the immune system. However, their role in the pathophysiology of syndromes induced by CTX or PbTx exposure is poorly documented. The aim of this review is to inventory the literature thus far on the inflammatory and immune effects of PbTxs and CTXs. Copyright © 2018 Elsevier Ltd. All rights reserved.

  18. The effects of cocoa on the immune system

    2013-06-01

    Full Text Available Cocoa is a food relatively rich in polyphenols, which makes it a potent antioxidant. Due to its activity as an antioxidant, as well as through other mechanisms, cocoa consumption has been reported to be beneficial for cardiovascular health, brain functions, and cancer prevention. Furthermore, cocoa influences the immune system, in particular the inflammatory innate response and the systemic and intestinal adaptive immune response. Preclinical studies have demonstrated that a cocoa-enriched diet modifies T-cell functions that conduce to a modulation of the synthesis of systemic and gut antibodies. In this regard, it seems that a cocoa diet in rats produces changes in the lymphocyte composition of secondary lymphoid tissues and the cytokines secreted by T cells. These results suggest that it is possible that cocoa could inhibit the function of Th2 cells, and in line with this, the preventive effect of cocoa on IgE synthesis in a rat allergy model has been reported, which opens up new perspectives when considering the beneficial effects of cocoa compounds. On the other hand, cocoa intake modifies the functionality of gut-associated lymphoid tissue by means of modulating IgA secretion and intestinal microbiota. The mechanisms involved in these influences are discussed here. Further research may elucidate the cocoa compounds involved in such an effect and also the possible medical approaches to these repercussions.

    Tattoo removal by laser therapy is a frequently performed procedure in dermatological practices. Quality-switched ruby, alexandrite, or Nd:YAG lasers are the most suitable treatment devices. Although these techniques are regarded as safe, both temporary and permanent side effects might occur. Little has been published on the frequency of complications associated with laser tattoo removal. We performed an Internet survey in German-speaking countries on characteristics of laser tattoo removal and associated side effects. A total number of 157 questionnaires entered the final analysis. Motivations for laser tattoo removal were mainly considering the tattoo as youthful folly (29%), esthetic reasons (28%), and 6% indicated medical problems. One third of participants were unsatisfied with the result of laser tattoo removal, and a complete removal of the tattoo pigment was obtained in 38% only. Local transient side effects occurred in nearly all participants, but an important rate of slightly visible scars (24%) or even important scarring (8%) was reported. Every fourth participant described mild or intense tan when the laser treatment was performed, and the same number of people indicated UV exposure following laser therapy, which should normally be avoided in these circumstances. As reported in the literature, nearly half of the participants experienced hypopigmentation in the treated area. Our results show that from the patients' point of view there is an important rate of side effects occurring after laser tattoo removal. Appropriate pretreatment counseling with regard to realistic expectations, possible side effects, and the application of test spots is mandatory to ensure patient satisfaction. Laser treatment should be performed by appropriately trained personnel only.

    Bartl, R; Bartl, C

    2015-12-01

    Osteoporosis is still an underdiagnosed and insufficiently therapied widespread disease in Germany. Of the estimated 7 million osteoporosis patients only 1.5 million receive a guideline conform diagnosis and even less receive appropriate treatment. Some 90 % of patients are provided with analgesics but only 10 % receive an effective therapy, although efficacious, well-tested and affordable medications are available. In addition, approximately one half of the patients terminate treatment after only 1 year although according to the results of recent studies the duration of therapy should be at least 3-5 years. In view of the increasing average life expectancy, a consistent management for prevention of fractures associated with osteoporosis is always most important for society, even if only for reasons of costs. Achievement of this target depends on four circumstances: clarification of the origin of osteoporosis and fractures (bone consciousness), prophylaxis of bone loss and fractures (primary prevention), consistent guideline conform diagnostics and therapy (secondary and tertiary prevention) and cooperation of all disciplines in medicine (bone is everybody's business). This article describes the current state of diagnostics (bone density measurement with dual X-ray absorptiometry, FRAX®), prophylaxis of fractures (screening program) and therapy (use of economic and effective medications with low side effects). Novel medications are already undergoing clinical testing and a "healing" of bone reduction with restoration of the normal bone structure is to be expected.

    To determine if inhaled 239 PuO 2 suppresses immunity in lung-associated lymph nodes, Chinese hamsters were exposed to a polydisperse aerosol of 239 PuO 2 produced at 1150 0 C. The mean lung burden of these animals was estimated to be 10 nCi at 8 days after exposure. At 128, 256 and 400 days after exposure, sham exposed controls and experimental animals were immunized by intratracheal instillation of 1 x 10 8 sheep red blood cells (SRBC). Six days later, they were sacrificed and the number of antibody forming cells (AFC) in lung-associated lymph nodes, spleen and cervical lymph nodes was evaluated. Results of these studies indicated that the number of AFC in lung-associated lymph modes was significantly lower in animals exposed to 239 PuO 2 . Only a few AFC were found in spleen and cervical lymph nodes after intratracheal immunization and the number in exposed animals was not significantly different than in the controls. These data indicate that even though the 239 PuO 2 exposure had suppressed immune responses in lung-associated lymph nodes, their filtering capacity was unaffected and antigen did not translocate to the spleen. We conclude that, at the sacrifice intervals evaluated, the immune function of lung-associated lymph nodes was suppressed and that distant lymphoid tissue (e.g., spleen and cervical lymph nodes) did not replace the immune function of the lung-associated lymph nodes

    The efficacy of immunization mandates for childcare or school entry is a long-standing controversy. The United States (US) adopted school entry immunization mandates in the 1800s, while most countries still do not have mandates. The objective of this systematic review was to analyze the evidence that immunization uptake increases with mandates. A search was conducted for studies that compared immunization uptake in a population prior to and after mandates, or in similar populations with one group having and the other not having mandates. Data were extracted and synthesized qualitatively due to the heterogeneity of study design. Eleven before-and-after studies and ten studies comparing uptake in similar populations with and without mandates were included. Studies were from the US (n = 18), France (n = 1) and Canada (n = 2). Eleven of the 21 studies looked at middle school mandates. All but two studies showed at least a trend towards increased uptake with mandates. Higher uptake was associated with a more long-standing mandate. Immunization mandates have generally led to increased short-term and long-term uptake in the group to whom the mandate applies. Many studies have centered around middle school mandates in the US and there is a paucity of studies of childcare mandates or of studies of mandates in other countries or in settings with relatively high baseline immunization uptake.

    Although the efficacy of racemate ketamine, a rapid onset and sustained antidepressant, for patients with treatment-resistant depression was a serendipitous finding, clinical use of ketamine is limited, due to psychotomimetic side effects and abuse liability. Behavioral and side-effect evaluation tests were applied to compare the two stereoisomers of ketamine. To elucidate their potential therapeutic mechanisms, we examined the effects of these stereoisomers on brain-derived neurotrophic factor (BDNF)–TrkB signaling, and synaptogenesis in selected brain regions. In the social defeat stress and learned helplessness models of depression, R-ketamine showed a greater potency and longer-lasting antidepressant effect than S-ketamine (esketamine). Furthermore, R-ketamine induced a more potent beneficial effect on decreased dendritic spine density, BDNF–TrkB signaling and synaptogenesis in the prefrontal cortex (PFC), CA3 and dentate gyrus (DG) of the hippocampus from depressed mice compared with S-ketamine. However, neither stereoisomer affected these alterations in the nucleus accumbens of depressed mice. In behavioral tests for side effects, S-ketamine, but not R-ketamine, precipitated behavioral abnormalities, such as hyperlocomotion, prepulse inhibition deficits and rewarding effects. In addition, a single dose of S-ketamine, but not R-ketamine, caused a loss of parvalbumin (PV)-positive cells in the prelimbic region of the medial PFC and DG. These findings suggest that, unlike S-ketamine, R-ketamine can elicit a sustained antidepressant effect, mediated by increased BDNF–TrkB signaling and synaptogenesis in the PFC, DG and CA3. R-ketamine appears to be a potent, long-lasting and safe antidepressant, relative to S-ketamine, as R-ketamine appears to be free of psychotomimetic side effects and abuse liability. PMID:26327690

    1988-01-01

    Generally non-ionic, water-soluble contrast media has been known to be considerably better than the conventional ionic contrast agents, because of its physiochemical properties which are more hydrophilic, lower in osmolality than the ionic agents of equivalent iodine concentration. It means that the non-ionic agent has less side reaction and better general tolerance. Iopromide (Ultavist) is a newly developed non-ionic contrast media that is suitable for angiography. Some non-ionic contrast media such as Metrizamide and lopamidol were clinically introduced and proved tobe the most compromising agents for neuroradiographic study, but lopromide is not yet freely available in the vascular study. In order to evaluate the clinical fitness and its side effects of lopromide for angiography various type of angiography were done in 136 patients using lopromide and 51 received Diatrizoate meglumine (DTM). Similar volumes of the contrast media was administered at similar rate to both groups. The results were as the follows: 1. In celiac angiography of 31 patients with lopromide (Ultravist 370) and 18 with DTM 60, there were observed 9.7% mild pain and 25.8% mild heat sensation in lopromide. In DTM 60 mild pain was approximately 3 times more frequently observed than lopromide. Heat sensation is mild and similar in frequency of both groups. There was no clinically significant side effects related to the osmolality and its difference between two groups. 2. In peripheral angiography of 47 patients with lopromide 300 and 24 with DTM 60, there were observed 19.1% mild, 6.4 moderate in pain and 46.8% mild, 1% moderate heat sensation in lopromide. But in DTM there were 33.3% mild, 58.3% moderate and 8.3% severe pain, and also 70.8% mild and 16.7% moderate heat sensation in DTM were observed. lopromide is more advantageous and better contrast agents than the DTM for peripheral vascular study on the point of low side effect related to osmolality. 3. In renal angiography, there was no

    Concerns regarding the use of efavirenz in patients with a history of mental illness may predispose clinicians to not offer this agent to psychiatrically ill populations in spite of the convenience of once daily dosing, which can result in improved adherence in these at-risk populations. This systematic review examines the current data regarding the neuropsychiatric effects of efavirenz, and also attempts to provide guidance to clinicians using efavirenz to treat patients with mental illness. The review identified high rates of neuropsychiatric side effects including vivid dreams, insomnia and mood changes in approximately 50% of patients who initiate efavirenz. The effects begin quickly, commonly peak in the first 2 weeks, and are generally mild and transient in nature. Isolated case reports and uncontrolled data suggest higher rates of severe side effects; however, there is no clear evidence of a broadly increased risk of suicide or dangerous behavior for patients taking efavirenz as part of their antiretroviral regimen.

    Accumulating evidence suggests that Japanese herbal medicines, called Kampo, have beneficial effects on cancer chemotherapy-induced side effects. Rikkunshito ameliorates cisplatin-induced anorexia through an antagonistic effect on the 5-HT receptors and by increasing the serum ghrelin levels. Hangeshashinto improves irinotecan-induced diarrhea and chemotherapy-induced mucositis by inhibiting the activity of β-glucuronidase as well as the synthesis of prostaglandin E2. Goshajinkigan prevents oxaliplatin-induced neurotoxicity, possibly through suppressing functional alterations of the transient receptor potential channels. In this review, we will summarize the currently available literature regarding the clinical efficacy and potential mechanisms of Kampo medicines in the treatment of cancer chemotherapy-induced side effects.

    Most pharmaceutical companies test their discovery-stage proprietary molecules in a battery of in vitro pharmacology assays to try to determine off-target interactions. During all phases of drug discovery and development, various questions arise regarding potential side effects associated with such off-target pharmacological activity. Here we present a scientific literature curation effort undertaken to determine and summarize the most likely functional and pathological outcomes associated with interactions at 70 receptors, enzymes, ion channels and transporters with established links to adverse effects. To that end, the scientific literature was reviewed using an on-line database, and the most commonly reported effects were summarized in tabular format. The resultant table should serve as a practical guide for research scientists and clinical investigators for the prediction and interpretation of adverse side effects associated with molecules interacting with components of this screening battery.

    Food additives are compounds used in order to improve food palatability, texture, and shelf life. Despite a significant effort to assure safety of use, toxicological analysis of these substances, generally, rely on their direct toxicity to target organs (liver and kidney) or their genotoxic effects. Much less attention is paid to the effects of these compounds on cells of the immune system. This is of relevance given that metabolic dysregulation and obesity have a strong immune-mediated component. Obese individuals present a state of chronic low-grade inflammation that contributes to the establishment of insulin resistance and other metabolic abnormalities known as the metabolic syndrome. Obesity and metabolic syndrome are currently recognized as worldwide epidemics that pose a profound socioeconomic impact and represent a concern to public health. Cells of the immune system contribute to both the maintenance of "lean homeostasis" and the metabolic dysregulation observed in obese individuals. Although much attention has been drawn in the past decades to obesity and metabolic syndrome as a result of ingesting highly processed food containing large amounts of fat and simple sugars, mounting evidence suggest that food additives may also be important contributors to metabolic derangement. Herein, we review pieces of evidence from the literature showing that food additives have relevant effects on cells of the immune system that could contribute to immune-mediated metabolic dysregulation. Considering their potential to predispose individuals to develop obesity and metabolic syndrome, their use should be taken with caution or maybe revisited.

    Sixty percent of cancer survivors are 65years of age or older. Cancer and its treatments lead to cancer-related fatigue and many other side effects, in turn, creating substantial global side-effect burden (total burden from all side effects) which, ultimately, compromises functional independence and quality of life. Various modes of exercise, such as yoga, reduce cancer-related fatigue and global side-effect burden in younger cancer survivors, but no studies have specifically examined the effects of yoga on older cancer survivors. The purpose of this study was to assess the effects of a 4-week yoga intervention (Yoga for Cancer Survivors: YOCAS©®) on overall cancer-related fatigue, and due to its multidimensional nature, the subdomains of cancer-related fatigue (general, physical, emotional, and mental) and global side-effect burden in older cancer survivors. We conducted a secondary analysis on data from a multicenter phase III randomized controlled clinical trial with 2 arms (standard care and standard care plus a 4-week YOCAS©® intervention). The sample for this secondary analysis was 97 older cancer survivors (≥60years of age), between 2months and 2years post-treatment, who participated in the original trial. Participants in the YOCAS©® intervention arm reported significantly lower cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden than participants in the standard care arm following the 4-week intervention period (peffective standardized yoga intervention for reducing cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden among older cancer survivors.

    2017-11-01

    To achieve the rebalance of flow distributions of double-sided impellers, a method of improving the radius of rear impeller is presented in this paper. It is found that the flow distributions of front and rear impeller can be adjusted effectively by increasing the radius of rear impeller, thus improves the balance of flow distributions of front and rear impeller. Meanwhile, the working conversion mode process of double-sided centrifugal compressor is also changed. Further analysis shows that the flowrates of blade channels in front impeller are mainly influenced by the circumferential distributions of static pressure in the volute. But the flowrates of rear impeller blade channels are influenced by the outlet flow field of bent duct besides the effects of static pressure distributions in the volute. In the airflow interaction area downstream, the flowrate of blade channel is obviously smaller. By increasing the radius of rear impeller, the work capacity of rear impeller is enhanced, the working mode conversion process from parallel working mode of double-sided impeller to the single impeller working mode is delayed, and the stable working range of double-sided compressor is broadened.

    During the helminth infections, the immune system tends to be modulated by host's sex hormones. Actually, many studies show the reciprocal relationship between sex steroids, the immune system and the elimination or establishment of helminth parasites. Is well known that innate immune response determines the type of adaptive immune response, so the effects in the innate immune response by hormones may affect subsequent adaptive immunity. The sex steroids as estrogens, progesterone and testosterone regulate growth, differentiation, survival and function of many cell types that could be involved in process like homeostasis and immunity, but also have a direct effect on the helminthes, that may probably be mediated by specific receptors on these parasites. Sex steroids, parasites and immunity are closely connected, and their interconnection is involved in the maintenance of elimination or establishment of helminthes in an immunocompetent host. For that reason, understanding the action's mechanisms of sex steroids on immune cells and its direct effect on helminth parasites is important for further progress in the development of novel therapies for chronic helminth diseases associated to immune dysregulation. In this review, we will describe the effects of sex steroids on the immune response during helminth infections as well as the direct effect in these parasites, and the possible implications of these effects on the incidence of several helminth infections.

    The nicotine-metabolite ratio (NMR) predicts treatment response and is related to treatment side effect severity. Sleep disturbance may be one important side effect, but understanding sleep disturbance effects on smoking cessation is complicated by the fact that nicotine withdrawal also produces sleep disturbance. To evaluate the effects of withdrawal and treatment side effects on sleep disturbance. This is a secondary analysis of data from a clinical trial (Lerman et al., 2015) of 1,136 smokers randomised to placebo ( n = 363), transdermal nicotine (TN; n = 381), or varenicline ( n = 392) and stratified based on NMR (559 slow metabolisers; 577 normal metabolisers). Sleep disturbance was assessed at baseline and at 1-week following the target quit date (TQD). We also examined whether sleep disturbance predicted 7-day point-prevalence abstinence at end-of-treatment (EOT). The varenicline and TN groups exhibited greater increases in sleep disturbance (vs. placebo; treatment × time interaction; p = 0.005), particularly among those who quit smoking at 1-week post-TQD. There was a main effect of NMR ( p = 0.04), but no interactions with treatment. TN and varenicline attenuated withdrawal symptoms unrelated to sleep (vs. placebo). Greater baseline sleep disturbance predicted relapse at EOT ( p = 0.004). Existing treatments may not mitigate withdrawal-related sleep disturbance and adjunctive treatments that target sleep disturbance may improve abstinence rates.

    2014-08-01

    To assess the psychiatric side effects of ketamine when administered in subanesthetic doses to hospitalized patients. It is hypothesized that such effects occur frequently. In this retrospective study, the medical records of 50 patients hospitalized on medical and surgical units at our facility who had continuous intravenous infusions of ketamine for pain or mild sedation were reviewed. Patient progress in the days following the start of ketamine infusion was reviewed and response to ketamine was noted. Twenty-two percent of the patients were noted to have some type of psychiatric reaction to ketamine, including agitation, confusion, and hallucinations. These reactions were relatively short lived, namely, occurring during or shortly after the infusions. No association was found between patient response to ketamine and gender, age, or infusion rate. Awareness of the psychiatric side effects of ketamine is an important consideration for clinicians administering this medication either for pain control or for depressive illness.

    Cordyceps sinensis (CS), a Chinese tonifying herb, has been widely used for centuries in Asian countries as a medicine and a health supplement. Although ample evidence indicates that CS can modulate immune responses, the functional effect of CS on dendritic cells (DCs) is still unclear. This study examines how CS affects human monocyte-derived DCs in two physiological states: naïve and LPS-induced inflammatory. Our experimental results demonstrate that CS acts as an activator and maturation inducer of immature DCs by stimulating the expression of costimulatory molecules and proinflammatory cytokines by DCs, enhancing the DC-induced, allogeneic T cell proliferation, and reducing the endocytic ability of DCs. In contrast, CS suppresses the LPS-induced, inflammatory response by decreasing the LPS-induced expression of costimulatory molecules and proinflammatory cytokines by DCs. CS also suppresses the LPS-induced, DC-elicited, allogeneic T cell proliferation and shifts the LPS-activated, DC-driven Th1 response toward a Th2 response. These results demonstrate that CS differentially regulates the DC activities according to the presence or absence of the inflammatory signs. Restated, with the lack of an ongoing inflammatory environment, CS primes DCs toward a Th1-type immunity, whereas in a potential inflammatory reaction, CS balances the over-reactivity of elicited Th1 immunity. This investigation illustrates the Yin-Yang balancing effects of CS as a medicine and a health supplement.

    2015-01-01

    Clozapine (CLZ) is the most effective treatment for treatment-resistant schizophrenia (SCZ) patients, with potential added benefits of reduction in suicide risk and aggression. However, CLZ is also mainly underused due to its high risk for the potentially lethal side-effect of agranulocytosis as well as weight gain and related metabolic dysregulation. Pharmacogenetics promises to enable the prediction of patient treatment response and risk of adverse effects based on patients' genetics, paving the way toward individualized treatment. This article reviews pharmacogenetics studies of CLZ response and side-effects with a focus on articles from January 2012 to February 2015, as an update to the previous reviews. Pharmacokinetic genes explored primarily include CYP1A2, while pharmacodynamic genes consisted of traditional pharmacogenetic targets such as brain-derived neurotrophic factor as well novel mitochondrial genes, NDUFS-1 and translocator protein. Pharmacogenetics is a promising avenue for individualized medication of CLZ in SCZ, with several consistently replicated gene variants predicting CLZ response and side-effects. However, a large proportion of studies have yielded mixed results. Large-scale Genome-wide association studies (e.g., CRESTAR) and targeted gene studies with standardized designs (response measurements, treatment durations, plasma level monitoring) are required for further progress toward clinical translation. Additionally, in order to improve study quality, we recommend accounting for important confounders, including polypharmacy, baseline measurements, treatment duration, gender, and age at onset.

    Full Text Available The effects of azadirachtin, a tetranortriterpenoid from the neem tree Aradirachta indica J. on both immunity and Trypanosoma cruzi interaction within Rhodniusprolixus and other triatomines, were presented Given through a blood meal, azadirachtin affected the immune reactivity as shown by a significant reduction in numbers of hemocytes and consequently nodule formation follwing challenge with Enterobacter cloacae ß12, reduction in ability to produce antibacterial activities in the hemolymph when injected with bacteria, and decreased ability to destroy the infection caused by inoculation of E. cloacae cells. A single dose of azadirachtin was able to block the development of T. cruzi in R. prolixus if given through the meal at different intervals, together with, before or after parasite infection. Similary, these results were observed with different triatomine species and different strains of T. cruzi. Azadirachtin induced a permanent resistance of the vector against reinfection with T. cruzi. The significance of these data is discussed in relation to the general mode of azadirachtin action in insects.

    Substantial progress has been made in China in using traditional Chinese medicine (TCM) to treat acquired immune deficiency syndrome (AIDS). Our objective was to review the latest developments in TCM treatment of AIDS in China between 2004 and 2014. We reviewed the content of original articles investigating the efficacy and safety of TCM for treating AIDS published in Chinese and English language journals. Relevant references from 2004 to 2014 were found using PubMed and the China National Knowledge Infrastructure Database. We found that TCM has been widely used for treating AIDS and its complications in China. The number of TCM studies has increased, which indicates efficacy and safety. Measures of efficacy in the reviewed articles included the alleviation of human immunodeficiency virus (HIV)-related signs and symptoms, improvements in quality of life, improvements in long-term survival, counteraction of the adverse side effects of antiviral drugs, promotion of immune reconstitution, and improvement of laboratory results. In sum, the literature indicates that TCM is safe. TCM plays an important role in the treatment of AIDS. Some studies have attempted to measure the efficacy and safety of TCM for treating AIDS, but more evidence is needed. Therefore, more research on this topic is required in the future.

    To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

    Deep brain stimulation of the medial globus pallidus is a surgical procedure for treating patients suffering from Parkinson's disease. Its therapeutic effect may be limited by the presence of pyramidal tract side effect (PTSE). PTSE is a contraction time-locked to the stimulation when the current spreading reaches the motor fibers of the pyramidal tract within the internal capsule. The lack of side-effect predictive model leads the neurologist to secure an optimal electrode placement by iterating clinical testing on an awake patient during the surgical procedure. The objective of the study was to propose a preoperative predictive model of PTSE. A machine learning based method called PyMAN (for Pyramidal tract side effect Model based on Artificial Neural network) that accounted for the current of the stimulation, the 3D electrode coordinates and the angle of the trajectory, was designed to predict the occurrence of PTSE. Ten patients implanted in the medial globus pallidus have been tested by a clinician to create a labeled dataset of the stimulation parameters that trigger PTSE. The kappa index value between the data predicted by PyMAN and the labeled data was .78. Further evaluation studies are desirable to confirm whether PyMAN could be a reliable tool for assisting the surgeon to prevent PTSE during the preoperative planning.

    Conventional 4-field box radiotherapy technique induces high morbidity for patients with localized prostatic cancer. Using a patient daily diary, the present study compared side-effects after conventional radiotherapy with conformal radiotherapy for prostate cancer. Fifty-eight patients treated with the conventional technique (with or without sucralfate) were compared with 72 patients treated with conformal technique. The patient groups were compared with an age-matched control population. Patients treated with conformal technique were also evaluated regarding acute and late urinary problems. Results showed that patients treated with conformal technique reported significantly fewer side-effects as compared with conventional technique. Patients treated with sucralfate also showed slightly decreased intestinal morbidity in comparison to non-sucralfate group. Acute and late morbidity evaluated by the patients was decreased after conformal radiotherapy as compared with the conventional technique. Sucralfate may be of value if conformal radiotherapy is used for dose escalation in prostatic cancer patients. (orig.)

    1997-01-01

    Purpose: To profile cancer patients aged 80 and older undergoing radiotherapy and to study the tumor response and side effects of therapy. Methods and Materials: We retrospectively analyzed the records of patients aged 80 and older who received radiation therapy at James A. Haley Veterans Hospital and H. Lee Moffitt Cancer Center between 1988 and 1995. A total of 203 patients aged 80-94 received radiotherapy during this period. Treatment sites included head and neck [50], breast [16], chest [37], pelvis [53], and miscellaneous [39]. Age, treatment site, field size, total dose, response to treatment, treatment interruptions, incidence and severity of weight loss, myelosuppression, diarrhea, mucositis, dermatitis, and follow-up status are assessed using our departmental records and hospital tumor registry. Results: Of 191 patients evaluated, 179 (94%) completed the treatment without serious complications. A total of 195 sites were irradiated. Twelve patients (6%) required interruption of the treatment. Therapeutic responses were seen in 86 out of 112 patients (77%) treated with curative intent (with 67% complete response) and in 67 out of 83 patients (81%) treated with palliative intent. The causes of treatment interruptions included weight loss from diarrhea, dysphagia, and progressive disease. Treatment interruptions were more likely in patients treated with large treatment fields. In patients treated for upper aero-digestive tract cancer, Grade 3 and 4 mucositis was noted in 20 and 2% of patients, respectively. Grade 1 and 2 enteritis was noted in 43% of patients treated for pelvic malignancies. Grade 3 dermatitis was noted only in 2% of patients. Conclusion: Radiotherapy is highly effective and well tolerated by the oldest old. Age is not a contraindication to aggressive radiotherapy

    Colorectal cancer (CRC) is one of the most prevalent forms of cancer that shows a high mortality and increasing incidence. There are numerous successful treatment options for CRC, including surgery, chemotherapy, radiotherapy and immunotherapy; however, their side effects and limitations are considerable. Probiotics may be an effective strategy for preventing and inhibiting tumour growth through stimulation of host innate and adaptive immunity. We investigated and compared potential anti-tumour immune responses induced by two isolated Lactobacillus strains, Lactobacillus plantarum A and Lactobacillus rhamnosus b, by pre-inoculating mice with lactobacilli for 14 days. Subsequently, subcutaneous and orthotopic intestinal tumours were generated in the pre-inoculated mice using CT26 murine adenocarcinoma cells and were assessed for response against the tumour. Our results indicated that oral administration with L. plantarum inhibited CT26 cell growth in BALB/c mice and prolonged the survival time of tumour-bearing mice compared with mice administered L. rhamnosus. L. plantarum produced protective immunity against the challenge with CT26 cells by increasing the effector functions of CD8+ and natural killer (NK) cell infiltration into tumour tissue, up-regulation of IFN-gamma (but not IL-4 or IL-17) production, and promotion of Th1-type CD4+ T differentiation. Consequently, our results suggest that L. plantarum can enhance the anti-tumour immune response and delay tumour formation.

    Pegylated-interferon-α/ribavirin (PEG-IFN/RBV) treatment can cure hepatitis C virus (HCV) infection but has frequent neuropsychiatric side-effects. Patients with pre-existing psychiatric illness may not be offered therapy. We established prevalence of self-reported psychiatric comorbidity among HCV-infected patients in a hospital-liver clinic, and determined the impact of such diagnoses on uptake and tolerance to PEG-IFN/RBV. All HCV cases referred for assessment in Australian Capital Territory/surrounding regions April 2004-March 2012 were entered into a clinical database. We conducted univariate and multivariate analyses of variables correlating with uptake of antiviral therapy and frequency of treatment-related side-effects. Of 773 referred patients, 235 (30%) described pre-existing psychiatric illness. Among these, 26% received antiviral therapy, compared with 30% of 538 without psychiatric comorbidity. History of depression (usually validated by liaison psychiatry) was associated with higher incidence of treatment-related neuropsychiatric side-effects (odds ratio 2.79 [1.35-5.70], P schizophrenia: three (11%) received antiviral therapy, compared with 30% admitting depression and 20% with bipolar affective disorder (all assessed by psychiatrist). In most schizophrenia cases, the reason for not offering antiviral treatment was psychological illness, yet none of five treated (these three plus two others in a psychiatric rehabilitation facility) experienced worsening psychiatric symptoms. A history of depression is common with hepatitis C but does not affect initiation of antiviral treatment, despite substantially increased risk of psychiatric side-effects. In contrast, pre-existing schizophrenia appears to influence treatment decisions, despite little evidence that PEG-IFN/RBV exacerbates the psychiatric condition, and well-supervised antiviral therapy can have good outcomes.

    Full Text Available OBJECTIVE: To assess household acceptability and perceived side effects of residual indoor pyrethroid (PYR, carbamate and organophosphate insecticides sprayed by annual rotation (ROT, spatial mosaic (MOS, and a single insecticide (DDT or PYR in communities of the coastal plain of Chiapas, Mexico. MATERIAL AND METHODS: A questionnaire to assess the acceptability and perceived side effects of indoor insecticides was administered to one member of 30% of the families in eight villages of Chiapas. The association of different insecticide treatments with their responses was evaluated (Chi-square. The intensity of side effects indicated under different treatments was compared in an ordered logistic model, using a severity index as the response variable. RESULTS: Insecticide spraying as a probable cause of symptoms was identified by 2.1% of interviewees. A significantly high percentage of persons with blurred vision, dizziness, sneezing, coughing, numbness, watery eyes, and itching lived in villages under MOS and ROT and a high severity index was significantly associated with ROT treatment. Reduction of mosquito bites and cockroaches were the perceived main benefits, and most villagers that perceived no benefits lived in DDT treated villages. Most of the interviewees welcomed spraying (83.7%, but the smell and having to remove furniture from houses were the main arguments against it. CONCLUSIONS: Acceptability correlated with insecticide spray coverage, although the most frequent suggestion for improvement was to increase the understanding of the objectives of spraying in the communities. The frequency of side effects was low, but higher in localities where a combination of insecticides was applied. This is a limitation for the use of this type of resistance management strategy in public health.

    2017-12-01

    Engineered nanoparticles (NPs) have broad applications in industry and nanomedicine. When NPs enter the body, interactions with the immune system are unavoidable. The innate immune system, a non-specific first line of defense against potential threats to the host, immediately interacts with introduced NPs and generates complicated immune responses. Depending on their physicochemical properties, NPs can interact with cells and proteins to stimulate or suppress the innate immune response, and similarly activate or avoid the complement system. NPs size, shape, hydrophobicity and surface modification are the main factors that influence the interactions between NPs and the innate immune system. In this review, we will focus on recent reports about the relationship between the physicochemical properties of NPs and their innate immune response, and their applications in immunotherapy.

    1988-01-01

    Changes in the content and function of cell populations and subpopulations involved in the humoral response of mice to the thymus-dependent antigen were investigated. The effect was followed during a prolonged continuous exposure to 137 C gamma-emitter (total dose - 5 Gy and daily dose - 12 cGy for 22 hours) and after its termination. The data obtained give evidence for a decrease of the pool of polypotent lymphocyte precursors (CFUs), stable moderate hypoplasia of central and peripheral organs of the immune system, distinct inhibition of antibody production at the expense of reduced activity of precursors of lymphocytes, B-lymphocytes and T-helpers. In the remote post-irradiation period residual radiation damage was seen in polypotent and committed precursors of lymphocytes and T-helpers, which was responsible for the trend towards the decline of antibody production, hypoplasia in the spleen and lymph nodes being persistent

  7. Hormonal contraception and physiology: a research-based theory of discontinuation due to side effects.

    2005-03-01

    Side effects influence the acceptability and continuation of hormonal contraceptives. Counseling the client about the management of side effects is a principal approach advocated for increasing continuation. Evidence of a biological basis for variation in women's tolerance of hormonal contraceptives argues, however, that greater attention should be given to altering the product rather than principally attempting to alter a woman's ability to deal with the product. Discontinuation rates for hormonal contraceptives, largely attributable to side effects and health concerns, are high in nearly all less-developed countries for which Demographic and Health Survey data are available. Oral contraceptives appear to be particularly problematic for Latin American women, most notably in Bolivia. Clinical trials suggest substantial variation in the physiological response to exogenous hormones, and new evidence confirms the hypothesis that the normal hormonal profiles of Bolivian women are significantly lower than those of women in the United States. These findings suggest a need for more population-specific physiological research linked to analyses of the possible association between endogenous hormone differences and contraceptive continuation. Appropriately adjusting the level of the steroid delivered may benefit women's health and improve the acceptability and continuation of hormonal contraceptives.

  8. A Rare Side Effect due to TNF-Alpha Blocking Agent: Acute Pleuropericarditis with Adalimumab

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

    The objective of this study was to assess side effects and satisfaction about OsteoCalVitFort (500 mg calcium and 400 I.U. of vitamin D3) usage. A total 186 people were participated with range age from 18 to 65 years old. Each participant received 1 pack that contains 60 OsteoCalVitFort tablet and used two tablet OsteoCalVitFort daily (1 tablet after breakfast and 1 after dinner). By a phone call, side effects and satisfaction about OsteoCalVitFort were assessed. The rate of constipating (8.0 %) and bloating (12.5 %) were decreased significantly after OsteoCalVitFort supplement intake (1.2 %, and 0.6 %, respectively). Similar results were observed in metallic taste in mouth, tiredness, weakness, loss of appetite, bone/muscle pain and mental/mood change after Calcium Vitamin D3 supplementation intake. Totally, 94 % of patients were satisfied about OsteoCalVitFort usage. The results of the research indicate despite the high quality of OsteoCalVitFort supplement, there are no side effects which have been seen in other supplements.

    One hundred and seventy patients with interstitial lung diseases undergoing bronchoalveolar lavage (BAL), were contrasted with 51 patients undergoing fibreoptic bronchoscopy alone to define the factors which predispose to post-lavage side-effects. Transient post-bronchoscopy fall in the peak expired flow (PEF) greater than or equal to 20% occurred in both groups (24% and 23% respectively), and thus was probably related to the bronchoscopy procedure. Post-lavage pyrexia (greater than or equal to 1 degree C) occurred only in the patients undergoing BAL (26%), p less than 0.001. Only 4% with pyrexia required antibiotics, and only 2% with falls in PEF needed bronchodilator therapy. The only significant clinical association was more frequent pyrexia in patients on treatment with prednisolone, particularly in women (p less than 0.01). Pyrexia was also associated with higher lavage fluid introduction volumes (greater than 240 ml). Side effects did not relate to the percentages of lavage fluid recovered, although smokers had lower recoveries and, recoveries tended to be higher in sarcoidosis than cryptogenic fibrosing alveolitis. Serial lavages in 25 patients caused no significant increase in side effects.

    Heisterkamp, A.; Ripken, T.; Mamom, T.; Drommer, W.; Welling, H.; Ertmer, W.; Lubatschowski, H.

    In order to evaluate the potential for refractive surgery, fs laser pulses of 150-fs pulse duration were used to process corneal tissue of dead and living animal eyes. By focusing the laser radiation down to spot sizes of several microns, very precise cuts could be achieved inside the treated cornea, accompanied with minimum collateral damage to the tissue by thermal or mechanical effects. During histo-pathological analysis by light and transmission electron microscopy considerable side effects of fs photodisruption were found. Due to the high intensities at the focal region several nonlinear effects occurred. Self-focusing, photodissociation, UV-light production were observed, leading to streak formation inside the cornea.

    Informing patients about treatment side effects increases the occurrence and intensity of side effects. Since the obligatory informed consent procedure in drug treatments requires transparency and nocebo research suggests that the informed consent of a drug leads to an increased occurrence of the mentioned side effects, the aim of this proof of concept study was to determine the effect of two different framings of informed consent on the occurrence, intensity, and perceived threat of side effects. Healthy male participants (n = 80) were randomized to one of two framing groups. The positive framing group was informed that the common side effect dizziness was a sign that the drug had started to work, while the neutral framing group was told that dizziness is an unpleasant but well-known side effect. Side effects were measured after the administration of metoprolol, an antihypertensive agent. Post hoc moderator analyses investigated the effect of pre-existing negative beliefs about the general harm of medication on the framing manipulation. Metoprolol-specific drug-attributed side effects were rated significantly less threatening in the positive framing group. The between-group effect size (Cohen's d) was small (d = 0.38, p = 0.049). Exploratory post hoc moderator analyses suggest that participants who believed that medication is a source of harmful effects benefited from positive framing, compared to neutral framing of drug-attributed side effects. Positive framing was partially effective in decreasing specific side effect measures, particularly among participants with a tendency to believe that medicine is harmful. Informed consent procedures should therefore be personalized, focusing on patients with negative treatment beliefs.

    Microparticles are polymeric bodies ranging 1-1000 µm that constitute a variety of forms such as microcapsules, microspheres, microcages, microshells, microrods, biosensors microparticles, radiolabeled microparticles, and so forth. This review focuses on general microparticles, mainly microcapsules and microspheres. Nonsteriodal anti-inflammatory drugs (NSAIDs) are one of the mostcommonly prescribed medications in the world. Most of the NSAIDs available have severe side effects. With increased awareness of NSAID-induced gastrointestinal (GI) side effects, safety has become a priority in treatment of arthritis and other inflammatory diseases with NSAIDs. A trend in NSAID development has been to improve therapeutic efficacy while reducing the severity of GI side effects by altering dosage through modified release to optimize drug delivery. One such approach is the use of fabricated microparticles such as microcapsules and microspheres as carriers of drugs. Microparticles provide delivery of macromolecules and micromolecules via different routes and effectively control the release profile of such drugs. Microcapsules and microspheres are compatible with most natural and synthetic polymers and can be used for several routes of administration, including parenteral, oral, nasal, intra-ocular, topical, and the like. Because of greater stability and multiple manufacturing techniques, microspheres and microcapsules are preferred as drug carriers over other colloidal drug delivery systems. Microparticles provide effective protection of the encapsulated agent against degradation by enzymatic activities, controlled and confined delivery of drugs from a few hours to months, and ingenious administration compared to alternative forms of controlled-release parenteral dosages, such as macro-sized implants. This comprehensive overview of fabricated microparticles describes microencapsulation technologies to produce microparticles for targeted therapy of arthritis and other

    Full Text Available Children with epilepsy have a high rate of mood and behavior problems yet few studies consider the emotional and behavioral impact of surgery. No study to date has been sufficiently powered to investigate effects of both side (left/right and site (temporal/frontal of surgery. One hundred patients (aged 6-16 and their families completed measures of depression, anxiety and behavioral function as part of neuropsychological evaluations before and after surgery for pharmacoresistant epilepsy. Among children who had left-sided surgeries (frontal=16; temporal=38, there were significant interactions between time (pre to postoperative neuropsychological assessment and resection site (frontal/temporal on Anhedonia, Social Anxiety, and Withdrawn/Depressed scales. Patients with frontal lobe epilepsy (FLE endorsed greater presurgical anhedonia and social anxiety than patients with temporal lobe epilepsy (TLE, with scores normalizing following surgery. While scores on the Withdrawn/Depressed scale were similar between groups before surgery, the FLE group showed greater symptom improvement after surgery. In children who underwent right-sided surgeries (FLE=20; TLE=26 main effects of time (patients in both groups improved and resection site (caregivers of FLE patients endorsed greater symptoms than those with TLE were observed primarily on behavior scales. Individual data revealed that a greater proportion of children with left FLE demonstrated clinically significant improvements in Anhedonia, Social Anxiety, and Aggressive Behavior than children with TLE. This is the first study to demonstrate differential effects of both side and site of surgery in children with epilepsy at group and individual levels. Results suggest that children with FLE have greater emotional and behavioral dysfunction before surgery, but show marked improvement after surgery. Overall, most children had good emotional and behavioral outcomes, with most scores remaining stable or improving.

    2005-01-01

    This paper examines the implications of SO 2 emission mitigation constraints in the power sector planning in Indonesia--a developing country--during 2003-2017 from a long term integrated resource planning perspective. A decomposition model is developed to assess the contributions of supply- and demand-side effects to the total changes in CO 2 , SO 2 and NO x emissions from the power sector due to constraints on SO 2 emissions. The results of the study show that both the supply- and demand-side effects would act towards the reduction of CO 2 , SO 2 and NO x emissions. However, the supply-side effect would play the dominant role in emission mitigations from the power sector in Indonesia. The average incremental SO 2 abatement cost would increase from US$ 970 to US$ 1271 per ton of SO 2 , while electricity price would increase by 2-18% if the annual SO 2 emission reduction target is increased from 10% to 25%

    Cigarette smoking has long been implicated in cancer development and survival. However, few studies have investigated the impact of smoking on symptom burden in cancer survivors during treatment and at survivorship stage. This study examines the influence of cigarette smoking on side effects among 947 cancer patients during and 6 months following treatment. Patients diagnosed with cancer and scheduled to receive chemotherapy and/or radiation therapy reported on current smoking status (yes, no) and total symptom burden [the sum of 12 common symptoms (fatigue, hair loss, memory, nausea, depression, sleep, pain, concentration, hot flashes, weight loss, skin problems, and dyspnea) scored on an 11-point scale ranging from 0 = "not present" to 10 = "as bad as you can imagine"] during treatment and at 6-month follow-up. The adjusted mean total symptom burden by smoking status was determined by analysis of covariance controlling for age, gender, race, education, occupation, treatment, cancer site, and Karnofsky performance score. During treatment, smokers (S) had a significantly higher total symptom burden than nonsmokers (NS) (S = 46.3 vs. NS = 41.2; p < 0.05). At 6-month follow-up, smokers continued to report a higher total symptom burden than nonsmokers (S = 27.7 vs. NS = 21.9; p < 0.05). Participants who quit smoking before treatment levels had a total symptom burden similar to nonsmokers. Smoking was associated with an increased symptom burden during and following treatments for cancer. Targeted cessation efforts for smokers to decrease symptom burden may limit the likelihood of treatment interruptions and increase quality of life following treatment.

    Full Text Available This study evaluated the effects of dietary anticoccidial drugs plus antibiotic growth promoters (AGPs on parameters of immunity in commercial broiler chickens. Day-old chicks were raised on used litter from a farm with endemic gangrenous dermatitis to simulate natural pathogen exposure and provided with diets containing decoquinate (DECX or monensin (COBN as anticoccidials plus bacitracin methylene disalicylate and roxarsone as AGPs. As a negative control, the chickens were fed with a non-supplemented diet. Immune parameters examined were concanavalin A (ConA-stimulated spleen cell proliferation, intestine intraepithelial lymphocyte (IEL and spleen cell subpopulations, and cytokine/chemokine mRNA levels in IELs and spleen cells. ConA-induced proliferation was decreased at 14 d post-hatch in DECX-treated chickens, and increased at 25 and 43 d in COBN-treated animals, compared with untreated controls. In DECX-treated birds, increased percentages of MHC2+ and CD4+ IELS were detected at 14 d, but decreased percentages of these cells were seen at 43 d, compared with untreated controls, while increased TCR2+ IELs were evident at the latter time. Dietary COBN was associated with decreased fractions of MHC2+ and CD4+ IELs and reduced percentages of MHC2+, BU1+, and TCR1+ spleen cells compared with controls. The levels of transcripts for interleukin-4 (IL-4, IL-6, IL-17F, IL-13, CXCLi2, interferon-γ (IFN-γ, and transforming growth factorβ4 were elevated in IELs, and those for IL-13, IL-17D, CXCLi2, and IFN-γ were increased in spleen cells, of DECX- and/or COBN-treated chickens compared with untreated controls. By contrast, IL-2 and IL-12 mRNAs in IELs, and IL-4, IL-12, and IL-17F transcripts in spleen cells, were decreased in DECX- and/or COBN-treated chickens compared with controls. These results suggest that DECX or COBN, in combination with bacitracin and roxarsone, modulate the development of the chicken post-hatch immune system.

    Purpose: To report the side effects and complications after I-125 seeds prostate implant after 8.5 years experience. Methods and materials: Six hundred and sixty seven (667) patients were treated between March 1995 and December 2001. The median follow up is 31 months with a maximum of 98.2 months. Morbidity data were collected from a review of patient case-notes. Patients also provided prospective data on urinary symptoms using the International Prostate Symptom Score (IPSS) scoring chart before treatment and at regular follow up. Patients were also sent a questionnaire detailing symptoms and side effects following their brachytherapy. This enabled them to record urinary, bowel and sexual function side effects independently. Logistic regression analysis was carried out to identify the risk of catheterisation in relation to the pre-implant prostate volume and potential implant factors such as the number of seeds and needles and implant dose. Result: The urinary symptom score rises in the first few months after implantation and returns to within one or two points of the pre-treatment score within one year. Nine patients reported incontinence prior to treatment and 15, 12 and 10 patients reported incontinence 6, 12 and 24 months after treatment, respectively. Catheterisation was reported in 97 (14.5%) patients. At six months 84.9% of patients reported no change in bowel function and 78.9% at 12 months. 6.4% of patients complained of some increased bowel frequency at 6 months and 5.7% at 12 months. 402 (77.2%) patients reported being fully potent before treatment and that this fell to 32.4% after treatment. Logistic regression showed that the most significant factors which correlate with the probability of catheterisation are the pre-treatment prostate volume and the number of seeds and needles implanted. Conclusion: The side effects and complications after prostate brachytherapy as reported here and elsewhere confirm that the treatment is not only convenient but also

    In this research, CFD simulations are performed for air vehicle configuration to compute the side force effect and yawing moment coefficients variations at high angle of attack and Mach numbers. As the angle of attack is increased then lift and drag are increased for cylinder body configurations. But when roll angle is given to body then side force component is also appeared on the body which causes lateral forces on the body and yawing moment is also produced. Now due to advancement of CFD methods we are able to calculate these forces and moment even at supersonic and hypersonic speed. In this study modern CFD techniques are used to simulate the hypersonic flow to calculate the side force effects and yawing moment coefficient. Static pressure variations along the circumferential and along the length of the body are also calculated. The pressure coefficient and center of pressure may be accurately predicted and calculated. When roll angle and yaw angle is given to body then these forces becomes very high and cause the instability of the missile body with fin configurations. So it is very demanding and serious problem to accurately predict and simulate these forces for the stability of supersonic vehicles.

    Full Text Available Objective: To investigate the effect of immune nutritional support on immune function and inflammatory factor in postoperative patients with gastric cancer. Methods: A total of 100 patients with gastric cancer were selected and randomly divided into the observation group and the control group with 50 cases in each group. The control group received routine perioperative enteral and parenteral nutrition, on the basis of conventional nutritional support, and the observation group was given enteral nutrition emulsion immune support. Then, the immune function and the inflammatory factor of postoperative day 1 and day 7 were compared between the two groups. Results: (1 With the preoperative data as the basis, the levels of serum IgG, IgA, C3 and C4 decreased at the postoperative day 1 and then increased at the postoperative day 7, while the level of IgM showed an increasing trend and then a decreasing trend in the two groups, and the corresponding figures for the postoperative day 1 and day 7 were statistically different between the two groups. In the observation group, the levels of IgG, IgA, C3 and C4 were higher, while the level of IgM was lower at the postoperative day 1 and day 7 than that in the control group, and the differences were statistically significant; (2 With the preoperative data as the basis, the levels of serum TNF-α, IL-6 and CRP significantly increased at the postoperative day 1 and then decreased at the postoperative day 7 in the two groups, and the corresponding figures for the postoperative day 1 and day 7 in the observation group were lower than those in the control group, and the differences were statistically significant. Conclusion: Immune nutritional support can help to reduce the damage of immune function and the inflammatory response induced by surgery in patients with gastric cancer, which is worthy of clinical application.

    Noise acts as a stressor and is reported to have impact on individual health depending on nature, type, intensity and perception. Modern medicine has no effective drugs or cure to prevent its consequences. Being an environmental stressor noise cannot be avoided; instead minimizing its exposure or consuming anti-stressor and adaptogens from plants can be considered. The present study was carried out to evaluate the anti-stressor, adaptogen and immunostimulatory activity of Scoparia dulcis against noise-induced stress in Wistar rat models. Noise stress in rats was created by broadband white noise generator, 100 dB A/4 h daily/15 days and S. dulcis (200 mg/kg b.w.) was administered orally. 8 groups of rats were used consisting of 6 animals each; 4 groups for unimmunized and 4 groups for immunized. For immunization, sheep red blood cells (5 × 10 9  cells/ml) were injected intraperitoneally. Sub-acute noise exposed rats showed a significant increase in corticosterone and IL-4 levels in both immunized and unimmunized rats whereas lymphocytes, antibody titration, soluble immune complex, IL-4 showed a marked increase with a significant decrease in IL-2, TNF-α, IFN-γ cytokines only in unimmunized rats. Immunized noise exposed rats presented increased leukocyte migration index and decreased foot pad thickness, IL-2, TNF-α, IFN-γ with no changes in the lymphocytes. S. dulcis (SD) has normalized and prevented the noise induced changes in cell-mediated and humoral immunity and it could be the presence of anti-stressor and immuno stimulant activity of the plant.

  4. The evaluation-mediation hypothesis: does the specification of potential side effects influence the perceived risk of medication?

    International Nuclear Information System (INIS)

    Reimer, T.

    1998-01-01

    Full text of publication follows: starting from the assumptions of support theory, this project analyzed the extent to which the specification of potential side effects influences the perceived risk associated, with a particular medication. Respondents were presented with an instruction leaflet for a medication which indicated (a) the overall probability that a side effect will occur or (b) the probability of occurrence of several specific side effects. Support theory predicts that the cognitive availability of potential side effects and therefore the perceived risk increases as a function of the specificity with which the side effects are presented. In contrast the evaluation-mediation hypothesis predicts that a more detailed presentation of potential side effects enhances the perceived quality of the information leaflet and thereby leads to a reduction of perceived risk. Support for the evaluation-mediation hypothesis was found in a series of studies which included the editing hypothesis and the elaboration likelihood model as additional explanations: the more detailed the information about potential side effects, the lower the estimated risk of suffering a side effect on taking the medication. As predicted, the influence of presentation specificity on perceived risk was mediated almost exclusively by the perceived quality of the information leaflet. A current series of studies seeks to support the evaluation-mediation hypothesis in a completely different domain, the perceived risk of environmental pollution by motor vehicles. (author)

  6. Effects of intensified training and taper on immune function

    2013-03-01

    Full Text Available Although resting immune function is not very different in athletes compared with non-athletes periods of intensified training (overreaching in already well trained athletes can result in a depression of immunity in the resting state. Illness-prone athletes appear to have an altered cytokine response to antigen stimulation and exercise. Having low levels of salivary IgA secretion also makes athletes more susceptible to upper respiratory tract infections. Overtraining is associated with recurrent infections and immunodepression is common, but immune functions do not seem to be reliable markers of impending overtraining. There are several possible causes of the diminution of immune function associated with periods of heavy training. One mechanism may simply be the cumulative effects of repeated bouts of intense exercise (with or without tissue damage with the consequent elevation of stress hormones, particularly glucocorticoids such as cortisol, causing temporary inhibition of TH-1 cytokines with a relative dampening of the cell-mediated response. When exercise is repeated frequently there may not be sufficient time for the immune system to recover fully. Tapering has been described as a gradual reduction in the training load which allows the recovery of physiological capacities that were impaired by previous intensive training and permits further training-induced adaptations to occur accompanied by competition performance enhancements. The majority of the studies that have examined the recovery of immunoendocrine responses during 1-3 week tapers in trained athletes have mainly reported enhanced performance, often accompanied by increased anabolic activity, reduced physiological stress and restoration of mucosal immunity and immune function.Quando se compara a função imune, em repouso, de atletas e não atletas, não se verificam grandes diferenças. Porém, períodos de treinamento intensificado ("overreaching" em atletas bem treinados podem

  7. Inverse targeting —An effective immunization strategy

    2012-05-01

    We propose a new method to immunize populations or computer networks against epidemics which is more efficient than any continuous immunization method considered before. The novelty of our method resides in the way of determining the immunization targets. First we identify those individuals or computers that contribute the least to the disease spreading measured through their contribution to the size of the largest connected cluster in the social or a computer network. The immunization process follows the list of identified individuals or computers in inverse order, immunizing first those which are most relevant for the epidemic spreading. We have applied our immunization strategy to several model networks and two real networks, the Internet and the collaboration network of high-energy physicists. We find that our new immunization strategy is in the case of model networks up to 14%, and for real networks up to 33% more efficient than immunizing dynamically the most connected nodes in a network. Our strategy is also numerically efficient and can therefore be applied to large systems.

  9. Combined effect of x irradiation and cell-mediated immune reaction

    Song, C.W.; Guertin, D.P.

    1978-01-01

    The combined effect of radiation and cell-mediated immune reaction on tumor cells was investigated in vitro. Mastocytoma P815-X2 cells of DBA mice either were irradiated first and subjected to immune lysis by immune splenic lymphocytes of C57Bl mice, or the tumor cells were subjected to immune reaction first and then irradiated. Cell survival was quantitated by colony formation in soft agar medium. It was observed that cellular immune damage to tumor cells did not influence the response of tumor cells to subsequent radiation. Irradiation of tumor cells first, followed by subjection of the cells to cellular immune reaction, slightly enhanced the death of the tumor cells. It appears that this enhanced death might have resulted from a relative increase in the ratio of the number of cytotoxic immune cells to the number of target tumor cells in the incubation mixture as a consequence of the decrease in the number of viable tumor cells by radiation

    The immune system can be the target of many chemicals, with potentially severe adverse effects on the host's health. In the literature, carbamate (CM) pesticides have been implicated in the increasing prevalence of diseases associated with alterations of the immune response, such as hypersensitivity reactions, some autoimmune diseases and cancers. CMs may initiate, facilitate, or exacerbate pathological immune processes, resulting in immunotoxicity by induction of mutations in genes coding for immunoregulatory factors and modifying immune tolerance. In the present study, direct immunotoxicity, endocrine disruption and inhibition of esterases activities have been introduced as the main mechanisms of CMs-induced immune dysregulation. Moreover, the evidence on the relationship between CM pesticide exposure, dysregulation of the immune system and predisposition to different types of cancers, allergies, autoimmune and infectious diseases is criticized. In addition, in this review, we will discuss the relationship between immunotoxicity and cancer, and the advances made toward understanding the basis of cancer immune evasion.

    Full Text Available Knowledge on side effects of pesticides on non-target beneficial arthropods is a key point in Integrated Pest Management (IPM. Here we present the results of four experiments conducted in vineyards where the effects of chlorpyrifos, thiamethoxam, indoxacarb, flufenoxuron, and tebufenozide were evaluated on the generalist predatory mites Typhlodromus pyri Scheuten and Amblyseius andersoni (Chant, key biocontrol agents of herbivorous mites on grapevines. Results show that indoxacarb and tebufenozide had a low impact on the predatory mites considered here, while a significant impact was observed for chlorpyrifos, flufenoxuron, and thiamethoxam. The information obtained here should be considered in the design of IPM strategies on grapevine.

    In a prospective randomized placebo controlled double blind study, the prophylactic effect of Mesalazine (5-aminosalicylic acid, 5-ASA) as suppositories (3x250 mg/day) on radiation induced proctitis during radiotherapy for prostatic carcinoma was studied. The study ended when 16 patients had been included (5-ASA: Eight, placebo: Eight) because of severe side effects in the 5-ASA group. 75% of patients treated with 5-ASA reported symptoms of a severe proctitis while only one patient in the placebo group had similar complaints. The application of Mesalazine as suppositories is not useful in preventing radiation induced proctitis during radiotherapy of prostate carcinoma.

    Full Text Available In this work the effects of the segmentation of the electrodes of Double Sided Silicon Strip Detectors (DSSSDs are investigated. In order to characterize the response of the DSSSDs we perform a first experiment by using tandem beams of different energies directly sent on the detector and a second experiment by mean of a proton microbeam. Results show that the effective width of the inter-strip region and the efficiency for full energy detection, varies with both detected energy and bias voltage. The experimental results are qualitatively reproduced by a simplified model based on the Shockley-Ramo-Gunn framework.

    2010-02-01

    Full Text Available Non-steroidal anti-inflammatory drugs like ibuprofen or indomethacin are commonly prescribed drugs to induce pharmacologic closure of a patent ductus arteriosus in preterm neonates. Based on a recently published Cochrane meta-analysis, both drugs are equally effective to induce closure. Drug choice can therefore be based on differences in side effects or pharmaco-economic arguments. The current review quantifies the negative impact of either ibuprofen or indomethacin on renal function, including diuresis, glomerular filtration rate and renal tubular function. Both ibuprofen and indomethacin have a quantifiable impact on renal function. However, compared to ibuprofen, the negative impact of indomethacin is more pronounced.

    Cancer-related fatigue, insomnia, and cancer-related cognitive impairment are commonly experienced symptoms that share psychological and physical manifestations. One or more of these symptoms will affect nearly all patients at some point during their course of treatment or survivorship. These side effects are burdensome and reduce patients' quality of life well beyond their cancer diagnosis and associated care treatments. Cancer-related fatigue, insomnia, and cancer-related cognitive impairment are likely to have multiple etiologies that make it difficult to identify the most effective method to manage them. In this review, we summarized the information on cancer-related fatigue, insomnia, and cancer-related cognitive impairment incidence and prevalence among breast cancer patients and survivors as well as recent research findings on pharmaceutical, psychological, and exercise interventions that have shown effectiveness in the treatment of these side effects. Our review revealed that most current pharmaceutical interventions tend to ameliorate symptoms only temporarily without addressing the underlying causes. Exercise and behavioral interventions are consistently more effective at managing chronic symptoms and possibly address an underlying etiology. Future research is needed to investigate effective interventions that can be delivered directly in clinic to a large portion of patients and survivors. © 2017 Wiley Periodicals, Inc.

    To evaluate the consumption, prevalence, side effects and awareness of energy drinks among female university students in Saudi Arabia. A quantitative research design was implied with sample size of 358 female students, recruited from Prince Sattam bin Abdulaziz University. The data, gathered through self-administered questionnaire, was analyzed through SPSS version 20.0 with p value energy drink consumers. The reasons for increased consumption of energy drinks mainly include giving company to friends (59.4%), better performance in exams (41.2%), and better concentration in studies (39.4%). The most common side effect was headache (32.3%), and the least was identified as allergy (2%). Only 39.4% and 29.9% of students acquired awareness regarding the harmful effects of energy drink consumption during pregnancy and breast feeding respectively. A significant proportion of female students at Prince Sattam bin Abdulaziz have reported to consume energy drinks regularly with several adverse effects. The government of Saudi Arabia should take serious initiatives towards organizing effective awareness programs specifically in universities and colleges to control the consumption of energy drinks and educate on the adverse effects.

    The objective of this study was to determine the efficacy of percutaneous radiofrequency (RF) treatment of the trigeminal ganglion for treating patients with trigeminal neuralgia, to determine which patients have a long-term benefit, and to evaluate the effect of RF parameters. A retrospective study in 28 consecutive patients in combination with a follow-up questionnaire (n = 26, 93% response). An initial treatment effect of 89% was observed, 60% sustained at 12-month follow-up. Major side effects were hypesthesia (56%), dry eye (20%), and masseter muscle weakness (12%). A lower sensory stimulation threshold during treatment was associated with better patient satisfaction (P = 0.016), improved pain relief (P = 0.039), and trended toward more hypesthesia (P = 0.077). This low-volume study reported treatment effects in an older population that were similar to previous studies. Only a higher incidence of hypesthesia was detected by long-term follow-up. This study supported the high efficiency of RF treatment, but there was a high level of side effects. Most notable, low sensory stimulation was associated with increased hypesthesia, whereas higher stimulation levels yielded less effectiveness. Further investigation of an optimal sensory stimulation range for percutaneous RF treatment of the trigeminal ganglion was found to be warranted. © 2013 World Institute of Pain.

    Identifying effective drug targets, with little or no side effects, remains an ever challenging task. A potential pitfall of failing to uncover the correct drug targets, due to side effect of pleiotropic genes, might lead the potential drugs to be illicit and withdrawn. Simplifying disease complexity, for the investigation of the mechanistic aspects and identification of effective drug targets, have been done through several approaches of protein interactome analysis. Of these, centrality measures have always gained importance in identifying candidate drug targets. Here, we put forward an integrated method of analysing a complex network of cancer and depict the importance of k-core, functional connectivity and centrality (KFC) for identifying effective drug targets. Essentially, we have extracted the proteins involved in the pathways leading to cancer from the pathway databases which enlist real experimental datasets. The interactions between these proteins were mapped to build an interactome. Integrative analyses of the interactome enabled us to unearth plausible reasons for drugs being rendered withdrawn, thereby giving future scope to pharmaceutical industries to potentially avoid them (e.g. ESR1, HDAC2, F2, PLG, PPARA, RXRA, etc). Based upon our KFC criteria, we have shortlisted ten proteins (GRB2, FYN, PIK3R1, CBL, JAK2, LCK, LYN, SYK, JAK1 and SOCS3) as effective candidates for drug development.

    Full Text Available Agricultural chemicals have been used extensively in modern agriculture and toxicological studies suggest a great potential for inducing undesirable effects on non target organisms. A model experiment was conducted in order to determine side effects of three nitrification inhibitors (NIs, 3,4dimethylpyrazolephosphate = DMPP, 4-Chlor-methylpyrazole phosphate = ClMPP and dicyandiamide = DCD on non target microbial processes in soils. Side effects and dose response curve of three NIs were quantified under laboratory conditions using silty clay, loam and a sandy soils. Dehydrogenase, dimethylsulfoxide reductase as well as nitrogenase activity (NA and potential denitrification capacity were measured as common and specific non target microbial processes. The influence of 5-1000 times the base concentration, dose response curves were examined, and no observable effect level = NOEL, as well as effective dose ED10 and ED50 (10% and 50% inhibition were calculated. The NOEL for microbial non target processes were about 30–70 times higher than base concentration in all investigated soils. The potential denitrification capacity revealed to be the most sensitive parameter. ClMPP exhibited the strongest influence on the non target microbial processes in the three soils. The NOEL, ED10 and ED50 values were higher in clay than in loamy or sandy soil. The NIs was the most effective in sandy soils.

    This paper presents the effects of water side deposits in the 210 MW coal fired thermal power plant components (viz., boiler, turbine, feed water heaters, condensers and lube oil coolers) on the energy efficiency of these components and that of the overall system at 100% maximum continuous rating (MCR). The origin, composition and rate of build up of deposits on the water side are presented. A linear growth rate of deposits is assumed for simplicity. The effects of the reduction in heat transfer, increased pressure drop and increased pumping power/reduced power output in the components are quantified in the form of curve fits as functions of the deposit thickness (μm). The reduction in heat transfer in the boiler components is in the range of 0.2-2.0% under normal scaling. The increased pumping power is of the order of 0.6-7.6% in the boiler components, 29% in the BFP circuit, 26% in the LPH circuit, 21% in the HPH circuit and 18% in the lube oil cooler circuits. The effects on the overall coal fired plant is quantified through functional relations between the efficiencies and the notional deposit thickness. The sensitivity indices to the notional deposit thickness are: boiler efficiency: -0.0021% points/μm, turbine circuit efficiency: -0.0037% points/μm, auxiliary power efficiency: -0.00129% points/μm, gross overall efficiency: -0.0039% points/μm and net overall efficiency: -0.0040% points/μm. The overall effect of scale build up is either increased power input of ∼68 kW/μm (at a constant power output) or decreased power output ∼25 kW/μm (at a constant power input). Successful contaminant control techniques are highlighted. Capacity reduction effects due to water side deposits are negligible

    Full Text Available Objectives: Chelating agents remain the mainstay in reducing the iron burden and extending patient survival in homozygous beta-thalassemia but adverse and toxic effects may increase with the institution and long term use of this essential therapy. This study aimed to estimate the incidence of deferasirox (DFX side effects in patients with thalassemia major or intermedia.Methods: A retrospective study of 72 patients (mean age: 20.3±0.9 yrs; 36 male, 36 female with thalassemia major or intermedia treated at Sultan Qaboos University Hospital, Oman, was performed to assess the incidence of side effects related to deferasirox over a mean of 16.7 month follow-up period.Results: Six patients experienced rashes and 6 had gastro-intestinal upset. DFX was discontinued in 18 patients for the following reasons: persistent progressive rise(s in serum creatinine (7 patients; 40% mean serum creatinine rise from baseline, feeling unwell (2, severe diarrhea (1, pregnancy (1, death unrelated to chelator (2 and rise in serum transaminases (2. Three patients were reverted to desferoxamine and deferiprone combination therapy as DFX was no longer biochemically effective after 18 months of therapy. There was no correlation between baseline serum ferritin and serum creatinine or a rise in serum creatinine. Cardiac MRI T2* did not change with DFX therapy. However, there was an improvement in liver MRI T2* (p=0.013.Conclusion: Renal side effects related to deferasirox appear to be higher than those reported in published clinical trials. Further larger studies are required to confirm these findings.

    The inconsistency in clinician and patient ratings of clozapine-induced side effects underscore the need to supplement clinician-based estimates of side effects with patient-reported ones. The main aims of the study are validation of the Glasgow antipsychotic side-effects scale for clozapine (GASS-C) in Serbian inpatients/outpatients with schizophrenia or schizo-affective disorder and recommendations for its future use, based on common and rare clozapine-associated side-effects. The GASS-C was administered to 95 outpatients/inpatients diagnosed with schizophrenia, schizoaffective, or chronic psychotic disorder. The scale showed good overall reliability, with an internal consistency coefficient of α = 0.84, an average retest coefficient of rho = 0.76, and a Spearman-Brown coefficient of validity of 0.81. Side effects were absent or mild in 64.2% of the patients, moderate in 31.6%, severe in 4.2%; 14% of the subjects considered their symptoms distressing. The most commonly reported side-effects were drowsiness, thirst, frequent urination, and dry mouth. Women reported more side effects than men, and patients not in a relationship reported significantly fewer side effects than patients in a relationship. Results indicate a weak positive correlation (rho = 0.231; p = .025) between severity of side effects and clozapine dose. The GASS-C showed good psychometric characteristics in clinical population of patients on clozapine. In future studies, clozapine serum concentrations should be measured when using the GASS-C to monitor side effects.

    Immune Thrombocytopenia (ITP) is characterised by an autoimmune antibody-mediated destruction of platelets and impaired platelet production. Few controlled trials exist to guide management of patients with ITP in Indian scenario for which patients require an individualized approach. Anti-D (Rho (D) immune globulin) at a higher dose can prove to be a cost effective and safe alternative for Indian patients with ITP. To compare the safety and efficacy of higher dose (75μg/kg) intravenous Anti-D immune globulin against the standard dose of 50μg/kg for the management of ITP in Indian patients. One hundred and sixty four children with newly diagnosed ITP between 4-14 years were randomly selected for inclusion and were treated with 50μg/kg (standard dose) or 75μg /kg (higher dose) of Anti-D to compare the efficacy and safety of higher dose intravenous anti-D immune globulin. Efficacy of Anti-D was measured in terms of rate of response and median time to response for increase in platelet counts. Any adverse event was noted. A decrease in haemoglobin concentration suggested accompanying haemolysis. Seventy one out of 84 patients treated with Anti-D at 75μg/kg produced complete response (85%) with median time of response being 2.5 days. On the contrary, 45 patients (70%) patients treated with 50μg/kg had complete response. However, there was no significant increase in haemolysis with higher dose. A significant correlation was found between dose and peak increase in platelet count measured at 7 th day following administration. However, there was no relationship between the decrease in haemoglobin and the dose given, or between the increase in platelet count and fall in haemoglobin. A 75μg/kg dose of Anti-D is more effective with acceptable side effect in comparison to 50μg dose for treatment of newly diagnosed Indian patients of ITP.

    The Clean Development Mechanism (CDM) under the Kyoto Protocol to the United Nations Framework Convention on Climate Change is considered a key instrument to encourage developing countries' participation in the mitigation of global climate change. Reduction of greenhouse gas (GHG) emissions through the energy supply and demand side activities are the main options to be implemented under the CDM. This paper analyses the general equilibrium effects of a supply side GHG mitigation option-the substitution of thermal power with hydropower--in Thailand under the CDM. A static multi-sector general equilibrium model has been developed for the purpose of this study. The key finding of the study is that the substitution of electricity generation from thermal power plants with that from hydropower plants would increase economic welfare in Thailand. The supply side option would, however, adversely affect the gross domestic product (GDP) and the trade balance. The percentage changes in economic welfare, GDP and trade balance increase with the level of substitution and the price of certified emission reduction (CER) units.

    Daikenchuto (DKT) has a stimulant effect on intestinal motility and reportedly has a positive effect on postoperative intestinal motility in patients with sigmoid colon cancer. In this study, we investigated the effects of DKT in patients with right-side colon cancer. This retrospective study included 88 patients with right-side colon cancer. We orally administered 7.5 g of DKT in the DKT group and did not administer any DKT to patients in the no-DKT group. All patients ingested radiopaque markers 2 h before surgery, which were used to assess intestinal motility. The postoperative intestinal motility was radiologically assessed by counting the numbers of residual markers in the large and small intestines. The DKT and no-DKT groups showed no marked differences in the total number of residual markers or number of residual markers in the small intestine. However, in the elderly subgroup, the total number of residual markers in the DKT group was significantly less than in the no-DKT group. Although DKT had some small effect on the postoperative intestinal motility for most patients, it may have positive effects in elderly patients.

    Full Text Available Objective Although the efficacy of Rubus coreanus (RC byproducts as a feed additive has been recognized, its effects on intestinal microorganisms and the immune system are still unknown. Methods Six-week-old male rats were treated with 0.5% RC (T1, 1.0% RC (T2, and 1.5% RC (T3 for 4 weeks. Results We found that treatment with RC byproducts significantly increased the daily gain of body weight and feed intake. Treg-cell differentiation was enhanced in the mesenteric lymph nodes and spleen from the rats fed with RC byproducts. Illumina sequencing showed that bacteria in the phylum Firmicutes decreased and while those in the phylum Bacteroidetes increased in RC-treated groups. Particularly, the pathogenic microorganisms in the family Peptococcaceae decreased, and the non-pathogenic families Lachnospiraceae and S24-7 increased. Quantitative polymerase chain reaction analysis showed that the RC byproducts increased the lactic acid bacteria Bifidobacterium spp., Oscillospira spp., Leuconostoc citreum, and Weissella cibaria in a concentration-dependent manner. Conclusion RC byproducts may be effective in immunomodulation by affecting intestinal microorganisms.

    Full Text Available Abstract Background The desired (therapeutic and undesired (side effects of methylphenidate might have underlying correlations. The aim of this study was to explore the strength and the possible sources of these correlations. Methods One hundred and fifty-seven children with ADHD (6-12 years were administered placebo and methylphenidate (0.5 mg/kg in a divided b.i.d. dose, each for a one-week period, in a double-blind, crossover trial. Therapeutic response was assessed using the Conners' Global Index for parents (CGI-Parents and teachers (CGI-Teachers, while side effects were assessed using the Barkley Side Effects Rating Scale (SERS. Results The side effect profile as assessed by the SERS was similar to that of previous studies with insomnia, decreased appetite, and headaches showing significant treatment effects (p Conclusion The greater "mood/anxiety" side effects on methylphenidate and placebo, the less the parents observe improvement of their children while treated with methylphenidate. This suggests that the correlations between "mood/anxiety" side effects and poor response to treatment may be driven by observer effects rather than biological commonalities between therapeutic and side effects of methylphenidate.

    Thoracic sympathectomy (TS) is the treatment of choice for severe primary hyperhidrosis. However, complications, side effects and satisfaction have not been well defined. To analyze the complications, side effects, satisfaction degree and quality of life of patients after TS for primary upper limb hyperhidrosis. One-year follow-up after 406 consecutive TS for primary upper limb hyperhidrosis. Bilateral TS was completed in all patients. Complications arose in 23 cases (5.6%), with pneumothorax being the most frequent. The success rate after discharge, 6 and 12 months was respectively, 100%, 98.1% and 96.5% for palmo-axillary hyperhidrosis; 100%, 99.3% and 97.8% for isolated palmar hyperhidrosis and 100%, 85.7% and 71.4% for isolated axillary hyperhidrosis. No persistence of hyperhidrosis was observed. Global recurrence was 3.7% (28.5% axillary hyperhidrosis group). Compensatory sweating (CS) appeared in 55% and was not related to the extension of the TS. Being female was a predisposing factor of CS (p<0.004). Excessive dryness appeared at 9% and was associated with extensive TS (P<0.001). Plantar hyperhidrosis improved at 33.6%, worsened at 10% and remained stable during the follow-up. Satisfaction degree decreased with the passage of time and was associated with recurrence. Quality of life was excellent at discharge, 6 and 12 month in 100%, 100% and 97%, respectively. Pneumothorax is the most frequent complication of TS. CS is the main and undesirable side effect, appears with the passage of time, and is not related to the extension of TS. Being female is the only predictor factor of suffering CS. Plantar hyperhidrosis improves initially, although tends to reappear. Excessive dryness appears in extensive TS and does not improve over time. Postoperative satisfaction degree is high but decreases over time owing to the appearance of recurrence. Effectiveness and the absence of CS determine an excellent quality of life. Six percent of the patients regret the surgery

    Introduction: This study was aimed to compare the efficacy and side effects of memantine, an antagonist of the NMDA receptor of glutamate, with risperidone given the fact that glutamate has been noted for its possible effects in the pathogenesis of autism. Risperidone, an atypical antipsychotic, has been approved by FDA for the management of irritability associated with autism. Methods: 30 children, aged 4-17 years, entered an 8-week, randomized trial. Patients were randomly assigned to receive either risperidone or memantine. Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), Clinical Global Impressions - Improvement (CGI-I) and Clinical Global Impression-Severity (CGI-S) scales were used to assess behavioral symptoms of the patients. Results: Both risperidone and memantine reduced the scores of 4 subscales of ABC as well as the 10-item and the total score of CARS significantly. However, differences between the 2 drugs in the scores of each evaluating scale were not found to be significant. Relatively, larger number of patients on risperidone showed "very much improvement" when assessed by CGI-I scale when compared with those on memantine. Discussion and conclusion: The present study suggests that memantine may have beneficial effects in the treatment of many core symptoms of autism. Therefore, memantine may be considered as a potential medication in the treatment of those autistic children who do not respond or cannot tolerate side effects of risperidone. © Georg Thieme Verlag KG Stuttgart · New York.

    Regan and Price (1994) investigated the frequency of occurrence and severity of side-effects of using an immersion virtual reality system in 150 subjects: 61% of the subjects reported symptoms of malaise at some point during a 20-min immersion and 10-min post-immersion period. This paper describes a double-blind placebo-controlled study that investigated whether 300 microgram of hyoscine/scopolamine hydrobromide administered to subjects prior to immersion in virtual reality was effective in reducing side-effects experienced during immersion. It was hypothesized that the hyoscine hydrobromide would cause a significant reduction in reported symptoms. We administered 300 micrograms of hyoscine hydrobromide to 19 subjects, and 20 subjects were administered a placebo compound 40 min prior to a 20-min immersion in VR. Data on malaise were collected using a simulator sickness questionnaire and a malaise scale. A 2 x 2 Chi-square analysis comparing the numbers of subjects reporting no symptoms on the malaise scale with those reporting some symptoms in the placebo and hyoscine conditions showed the differences between the two groups to be statistically significant at the 0.01 level (Chi-square = 7.392 with 1 df, p = 0.007). This difference was clearly in the direction of fewer symptoms being reported in the hyoscine condition. The results of the study showed that the hyoscine was effective in reducing symptoms that are commonly observed during immersion in virtual reality.

    Background: The documentation of acute and chronic treatment sequelae is a decisive precondition for the appropriate evaluation of the treatment quality of any cancer therapy. Methods and results: Interdisciplinary (inter)national efforts have resulted in a new consensus for recording of treatment sequelae in oncology. While the acute treatment side effects (day 1 to 90 after treatment) are recommended to be documented and evaluated using the Common Toxicity Criteria (CTC), for the chronic treatment side effects (day 91 and thereafter) the Late Effect Normal Tissue (LENT) criteria are to be implemented. The latter classification system allows to differentiate between the Subjective, Objective, Management and Analytic (SOMA) toxicity aspects. Both classification systems can be implemented not only for clinical applications using radiotherapy or chemotherapy alone but also for combinations with each other or with other treatment modalities. This allows for an effective interdisciplinary comparison between different treatment concepts not only within each institution but also in multicenter trials. Conclusions: Prospective documentation and evaluation of treatment toxicity in oncology should be intensified and systematically included in future mono- and multi-institutional clinical trials.

    Full Text Available Propofol is one of the main sedatives but its negative side effects limit its clinical application. Chitosan oligosaccharide (COS, a kind of natural product with anti-pain and anti-inflammatory activities, may be a potential adjuvant to propofol use. A total of 94 patients receiving surgeries were evenly and randomly assigned to two groups: 10 mg/kg COS oral administration and/or placebo oral administration before being injected with propofol. The target-controlled infusion of propofol was adjusted to maintain the values of the bispectral index at 50. All patients’ pain was evaluated on a four-point scale and side effects were investigated. To explore the molecular mechanism for the functions of COS in propofol use, a mouse pain model was established. The activities of Nav1.7 were analyzed in dorsal root ganglia (DRG cells. The results showed that the patients receiving COS pretreatment were likely to require less propofol than the patients pretreated with placebo for maintaining an anesthetic situation (p < 0.05. The degrees of injection pain were lower in a COS-pretreated group than in a propofol-pretreated group. The side effects were also more reduced in a COS-treated group than in a placebo-pretreated group. COS reduced the activity of Nav1.7 and its inhibitory function was lost when Nav1.7 was silenced (p > 0.05. COS improved propofol performance by affecting Nav1.7 activity. Thus, COS is a potential adjuvant to propofol use in surgical anesthesia.

    Breast cancer is the most common cancer type among women necessitating adjuvant radiotherapy. As the Internet has become a major source of information for cancer patients, this study aimed to evaluate the quality of websites giving information on side effects of radiotherapy for breast cancer patients. A patients' search for the English terms "breast cancer - radiotherapy - side effects" and the corresponding German terms "Brustkrebs - Strahlentherapie - Nebenwirkungen" was carried out twice (5 months apart) using the search engine Google. The first 30 search results each were evaluated using the validated 16-question DISCERN Plus instrument, the Health on the Net Code of Conduct (HONcode) certification and the Journal of the American Medical Association (JAMA) benchmark criteria. The overall quality (DISCERN score) of the retrieved websites was further compared to queries via Bing and Yahoo search engines. The DISCERN score showed a great range, with the majority of websites ranking fair to poor. Significantly superior results were found for English websites, particularly for webpages run by hospitals/universities and nongovernmental organizations (NGO), when compared to the respective German categories. In general, only a minority of websites met all JAMA benchmarks and was HONcode certified (both languages). We did not determine a relevant temporal change in website ranking among the top ten search hits, while significant variation occurred thereafter. Mean overall DISCERN score was similar between the various search engines. The Internet can give breast cancer patients seeking information on side effects of radiotherapy an overview. However, based on the currently low overall quality of websites and the lack of transparency for the average layperson, we emphasize the value of personal contact with the treating radio-oncologist in order to integrate and interpret the information found online.

      The long-term patient satisfaction and safety of nightguard vital bleaching (NGVB) requires further evaluation.   The purpose of this study was to evaluate patients' satisfaction and identify side effects of NGVB up to 17 years post-treatment.   Thirty-one participants who had completed previous NGVB studies using 10% carbamide peroxide were contacted at least 10 years post-treatment (range 10-17 years, average 12.3 years). Participants reported shade satisfaction (very satisfied [VS], partially satisfied [PS], or not satisfied [NS]) as well as potential complications. Participants had teeth # 6 to 11 examined for tooth vitality, gingival inflammation (Löe's Gingival Index [GI]), and radiographically for external cervical resorption (ECR).   All of the participants had successful lightening of their teeth. Sixty-one percent (19) had not retreated their teeth. Of those who had not retreated their teeth and who responded to the question of whitening satisfaction, 31% (4/13) were VS, 54% (7/13) were PS, and 15% (2/13) were NS with their current shade. Of those who had retreated their teeth, all were VS or PS. Ninety-one percent of the examined teeth had GI = 0 (normal), 7% had GI = 1 (mild inflammation), and 2% had GI = 2 (moderate inflammation). Sixty-nine percent of teeth tested responded to a cold stimulus. Radiographs did not detect ECR or apical lesions. No participant reported having a gingival biopsy post-treatment, and 87% would whiten again.   Patient satisfaction with NGVB may last as long as 12.3 years in average (range 10-17 years) post-treatment. GI and ECR findings were considered within the normal expectations for the sample studied, suggesting minimal clinical post-NGVB side effects up to 17 years. Nightguard vital bleaching provides patient satisfaction with minimal side effects up to 17 years post-treatment. © 2011 Wiley Periodicals, Inc.

    Patients with treatment-resistant obsessive-compulsive disorder (OCD) are potential candidates for deep brain stimulation (DBS). The anteromedial subthalamic nucleus (STN) is among the most commonly used targets for DBS in OCD. We present a patient with a 30-year history of treatment-resistant OCD who underwent anteromedial STN-DBS. Despite a clear mood-enhancing effect, stimulation caused motor side effects, including bilateral hyperkinesia, dyskinesias, and sudden large amplitude choreatic movements of arms and legs when stimulating at voltages greater than approximately 1.5 V. DBS at lower amplitudes and at other contact points failed to result in a significant reduction of obsessions and compulsions without inducing motor side effects. Because of this limitation in programming options, we decided to reoperate and target the ventral capsule/ventral striatum (VC/VS), which resulted in a substantial reduction in key obsessive and compulsive symptoms without serious side effects. Choreatic movements and hemiballismus have previously been linked to STN dysfunction and have been incidentally reported as side effects of DBS of the dorsolateral STN in Parkinson disease (PD). However, in PD, these side effects were usually transient, and they rarely interfered with DBS programming. In our patient, the motor side effects were persistent, and they made optimal DBS programming impossible. To our knowledge, such severe and persistent motor side effects have not been described previously for anteromedial STN-DBS. Copyright © 2017 Elsevier Inc. All rights reserved.

    Side-contacted Fild Effect Diode (S-FED), with low leakage current and high Ion/Ioff ratio, has been recently introduced to suppress short channel effects in nanoscale regime. The voltage and size scalability of S-FEDs and effects on the power consumption, propagation delay time, and power delay product have been studied in this article. The most attractive properties are related to channel length to channel thickness ratio in the S-FED which reduces in comparison with MOSFET significantly, while gates control over the channel improve and the off-state current reduces dramatically. This promising advantage is not only capable to improve important S-FED's characteristics such as subthreshold slope but also eliminate Latch-up and floating body effect.

    To study the possible effect of the side pinch on the steady-state current and the steady-state shock speed of a magnetically driven shock tube, a semiempirical model is formulated. The time history of the current, the radial and the translational motion of the current-carrying region are expressed...... by three interacting nonlinear equations with five adjustable parameters describing the variation of the electric circuit elements, the geometry of the shock tube, and the initial running conditions. Within the range of practical interest for values of the parameters investigated, computational results...

    Full Text Available Abstract Background Patient-reported side effect questionnaires offer a simple method for the systematic measurement of drug-related side effects. In order to measure patients' inhaled corticosteroids (ICS related side effect perceptions the 14-day retrospective Inhaled Corticosteroid Questionnaire (ICQ was developed. In this research we aim to assess the construct validity and reliability of the ICQ and test its responsiveness to dose changes in adult asthma patients. Methods In a cross-sectional study, current inhaler users with asthma completed the ICQ (27 with non ICS inhaler; 61 BDP equivalent daily ICS low dose ≤400 μg; 62 mid dose 401–800 μg; and 105 with high dose >800 μg. We generated 3 construct validity hypotheses: 1 a hierarchical dose-response pattern for scoring of the individual items on the ICQ, and statistically significant differences in the scores of each of the 15 ICQ domains by ICS dose group 2 an association between ICS dose and ICQ scoring after adjusting for appropriate confounders in multiple regression; 3 greater convergence between local side effect domains than between systemic and local domains of the scale. Test-retest reliability was assessed on a randomly selected subgroup of patients (n = 73 who also completed the ICQ a second time after 7 days. In a separate longitudinal study, 61 patients with asthma completed the ICQ at baseline and after changing their daily ICS dose, at 2- and 6- months, in order to test the ICQ's responsiveness. Results All three construct validity hypotheses were well supported: 1 a statistically significant difference existed in scores for 14 domains, the high ICS dose group scoring highest; 2 ICS dose independently predicted ICQ scoring after adjusting for confounders; 3 greater convergence existed between local ICQ domains than between local and systemic domains. The ICQ had good reproducibility: test-retest intraclass correlation coefficients were ≥0.69 for all but the 'Facial

    Psychotropic medications are often prescribed to reduce challenging behavior in individuals with intellectual and developmental disabilities (IDD). Functional analyses (FAs) have demonstrated utility in assessing medication impact on behavior; however, the impact of adverse side effects (ASE) on challenging behavior is under-assessed. The purpose of this study was to develop a methodology, similar to FAs, to explore potential medication ASE impact on challenging behavior in seven individuals with IDD. Results revealed response rate differences in designed ASE conditions for most participants. Outcomes support further development and use of this methodology to assess the presence and impact of ASEs.

    The use of anabolic steroids is prevalent in recreational athletes. This case report describes a young amateur bodybuilder who was referred to our outpatient clinic with jaundice and loss of appetite due to cholestatic hepatitis. Additional tests including a liver biopsy made it likely that the hepatitis was caused by the injectable anabolic steroid trenbolone enanthate. Cholestatic hepatitis may not be limited to the use of oral anabolic-androgenic steroids, as is widely assumed. Therefore, and because of other side effects, the recreational use of all forms of anabolic steroids should be discouraged.

    After surgical removal of a carcinoma of the breast, 79 women received postoperative telecobalt-60 irradiation as out-patients. Prior to irradiation high doses of venoruton intens (1500 mg HR/die) were administered in order to obtain radioprotective properties of the skin, the subcutaneous fatty tissue and the lymphatic system of the irradiated regions. A strikingly small number of brachial oedemas and subcutaneous indurations following telecobalt-60 irradiation was found under HR treatment. Irradiation was carried out in the out-patient department with relatively high single doses without interruptions caused by radiotherapy. The high doses of HR did not entail any side-effects.

    The cellular basis of immunity to sporozoites was investigated by examining the effect of immunization of T and B cell-deficient C57BL/6N x BALB/c AnN F 1 (BLCF 1 ) mice compared to immunocompetent controls. Immunization of T cell-deficient (ATX-BM-ATS) BLCF 1 mice with x-irradiated sporozoites did not result in the generation of protective immunity. The same immunization protocols protected all immunocompetent controls. In contrast, B cell-deficient (μ-suppressed) BLCF 1 mice were protected by immunization in the majority of cases. The absence of detectable serum circumsporozoite precipitins or sporozoite neutralizing activity in the μ-suppressed mice that resisted a sporozoite challenge suggests a minor role for these humoral factors in protection. These data demonstrate a preeminent role for T cells in the induction of protective immunity in BLCF 1 mice against a P. berghei sporozoite infection

    Evidence-based integrative medicine therapies have been introduced to promote wellness and offset side-effects from cancer treatment. Energy medicine is an integrative medicine technique using the human biofield to promote well-being. The biofield therapy chosen for study was Therapeutic Touch (TT). Breast cancer tumors were initiated in mice by injection of metastatic 66cl4 mammary carcinoma cells. The control group received only vehicle. TT or mock treatments were performed twice a week for 10 minutes. Two experienced TT practitioners alternated treatments. At 26 days, metastasis to popliteal lymph nodes was determined by clonogenic assay. Changes in immune function were measured by analysis of serum cytokines and by fluorescent activated cells sorting (FACS) of immune cells from the spleen and lymph nodes. No significant differences were found in body weight gain or tumor size. Metastasis was significantly reduced in the TT-treated mice compared to mock-treated mice. Cancer significantly elevated eleven cytokines. TT significantly reduced IL-1-a, MIG, IL-1b, and MIP-2 to control/vehicle levels. FACS demonstrated that TT significantly reduced specific splenic lymphocyte subsets and macrophages were significantly elevated with cancer. Human biofield therapy had no significant effect on primary tumor but produced significant effects on metastasis and immune responses in a mouse breast cancer model.

    In this article, a research project on mobile safe food consumption system (FoodWiki) is discussed that performs its own inferencing rules in its own knowledge base. Currently, the developed rules examines the side effects that are causing some health risks: heart disease, diabetes, allergy, and asthma as initial. There are thousands compounds added to the processed food by food producers with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. Those commonly used ingredients or compounds in manufactured foods may have many side effects that cause several health risks such as heart disease, hypertension, cholesterol, asthma, diabetes, allergies, alzheimer etc. according to World Health Organization. Safety in food consumption, especially by patients in these risk groups, has become crucial, given that such health problems are ranked in the top ten health risks around the world. It is needed personal e-health knowledge base systems to help patients take control of their safe food consumption. The systems with advanced semantic knowledge base can provide recommendations of appropriate foods before consumption by individuals. The proposed FoodWiki system is using a concept based search mechanism that performs on thousands food compounds to provide more relevant information.

    No study has tested the effectiveness of individualized cognitive behavioral therapy (CBT) interventions to reduce persistent nausea, pain, anxiety, and fatigue in patients on continuous antiretroviral therapy (ART). Our objective was to determine if CBT could reduce nausea, pain, anxiety, and fatigue in patients with HIV on ART. Men ages 40 to 56 years on ART (n = 18) at a suburban HIV clinic were randomly assigned to a control group or the CBT intervention. Usual adherence education and side-effect management were provided to both groups. Symptoms, health perception, medication adherence, and side-effect-reducing medication use were measured at four time points over 3 months. Participants in the intervention group rated usual fatigue and worst fatigue at 60 days, and nausea duration at 90 days significantly lower than controls (p < .05). Brief CBT training may reduce fatigue and nausea in patients with HIV undergoing ART. Copyright © 2016 Association of Nurses in AIDS Care. Published by Elsevier Inc. All rights reserved.

Here, we report the case of an 83-year-old woman who was prescribed quetiapine (50 mg per day for delirium. Unexpected, global aphasia occurred 3 days after treatment began. Complete recovery occurred following discontinuation of the drug. A brain computed tomography scan excluded intracranial hemorrhage and the laboratory results confirmed that no exacerbation of infection or electrolyte imbalances were present. During the aphasic episode, the patient’s condition did not deteriorate and no new neurological symptoms occurred. We suspect that the occurrence of aphasia was directly due to an adverse reaction to quetiapine. To our knowledge, this is the first case report of reversible, global aphasia as a side effect of quetiapine. We propose that this occurrence of aphasia may be due to the action of quetiapine as a dopamine receptor antagonist. Clinicians should use quetiapine with caution, especially in elderly patients. On observation of aphasia, a review of the patient’s medical history is required to assess for the usage of quetiapine. Keywords: aphasia, quetiapine, insomnia, delirium

    2018-04-01

    Drug side effects are one of the public health concerns. Using powerful machine-learning methods to predict potential side effects before the drugs reach the clinical stages is of great importance to reduce time consumption and protect the security of patients. Recently, researchers have proved that the central nervous system (CNS) side effects of a drug are closely related to its permeability to the blood-brain barrier (BBB). Inspired by this, we proposed an extended neighborhood-based recommendation method to predict CNS side effects using drug permeability to the BBB and other known features of drug. To the best of our knowledge, this is the first attempt to predict CNS side effects considering drug permeability to the BBB. Computational experiments demonstrated that drug permeability to the BBB is an important factor in CNS side effects prediction. Moreover, we built an ensemble recommendation model and obtained higher AUC score (area under the receiver operating characteristic curve) and AUPR score (area under the precision-recall curve) on the data set of CNS side effects by integrating various features of drug.

  20. Comparison of side effects of oxytetracycline and talc pleurodesis: an experimental study

    2010-01-01

    Background Chemical pleurodesis is widely recommended in the treatment of refractory pleural effusion or pulmonary air leak of different etiologies. Although several agents have been used, many questions have remained unanswered about their toxicity. Talc is the most commonly used agent for the treatment, with rare, serious complications reported. Oxytetracycline pleurodesis in clinical practice has been described in a few studies, but literature reveals no experimental studies using this agent. We performed a prospective, randomized, observer-blinded, controlled study to evaluate the changes in lung histology and systemic response to pleurodesis with oxytetracycline and talc in acute and subacute phases in a rat model. Methods Forty-two male albino Wistar rats were divided into three groups and 3 subgroups with 7 animals in each. Group 1 was given oxytetracycline, 35 mg/kg; Group 2 was given talc slurry, 60 mg/kg in 0.5 mL saline solution, and Group 3 was given only 0.5 mL saline intrapleurally. In subgroups "a" the nimls were sacrificed at the postoperative 72nd hour and, in subgroups "b", on the postoperative day 7. The surfaces were graded by microscopic examination. Results Oxytetracycline produced alveolar collapse, hemorrhage, edema, inflammation at the postoperative 72nd hour and hemorrhage on the postoperative day 7, while talc produced significant edema, inflammation, proliferation, fibrosis at the postoperative 72nd hour and hemorrhage, edema, inflammation, proliferation, and fibrosis on the postoperative day 7 (p oxytetracycline on the postoperative day 7. On contralateral side, oxytetracycline and talc produced significant hemorrhage on the postoperative day 7 (p oxytetracycline were more pronounced, whereas the side effects of talc were prolonged to subacute phase. We propose that the occasional side effects in humans may be related to these changes as were observed in our rat model, and like talc, oxytetracycline must be used cautiously in patients

  1. Linalool Exhibits Cytotoxic Effects by Activating Antitumor Immunity

    Full Text Available According to recent studies, the Plantaginaceae, which are traditional Chinese herbal remedies, have potential for use in viral infection treatment and cancer therapy. Linalool and p-coumaric acid are two of the biologically active compounds that can be isolated from the Plantaginaceae. This study mainly focused on investigating the bioactivity of linalool as well as the bioactivity of p-coumaric acid in terms of their cytotoxic effects on cancer cells. Whether the mechanisms of such effects are generated through apoptosis and immunoregulatory activity were also investigated. By using WST-1 analysis, it was shown that linalool and p-coumaric acid have good inhibitory effects against breast, colorectal and liver cancer cells. The IC50 values of linalool for those cancer cell types were 224 μM, 222 μM, and 290 μM, respectively, and the IC50 values of p-coumaric acid were 693 μM, 215 μM and 87 μM, respectively. Cell cycle analysis also confirmed that linalool and p-coumaric acid can lead to apoptosis. By using flow cytometry, it was determined that treatment with linalool rather than p-coumaric acid significantly increased the sub-G1 phase and that there were more cells concentrated in the G1 phase. Furthermore, by using cytokine array analysis, we found that linalool can stimulate IFN-γ, IL-13, IL-2, IL-21, IL-21R, IL-4, IL-6sR and TNF-α secretion. This demonstrated that in addition to the bidirectional regulation capabilities found in linalool, it also induces Th1 cellular immune response in T-47D cells. These results showed that linalool holds great potential for use in cancer therapy, and we believe that it could provide an alternative way to take action against tumors.

    Diabetes Mellitus type 2 is very common worldwide, with majority of cases in Asia Pacific region. Metformin is the first line therapy, along with lifestyle modification for all type 2 diabetics as recommended by ADA. Metformin is available as conventional Metformin Immediate Release (MIR) and Metformin Extended Release (MXR). Metformin XR has better gastrointestinal tolerability and fewer side effects as compared to Metformin IR, with similar efficacy regarding anti-hyperglycaemic effects. The objective of this study was to determine whether metformin XR is as effective as Metformin IR in maintaining glycaemic control at equivalent doses or even at reduced doses; and to compare the side effect profile of the two preparations. Methods: This randomized control trial was conducted at Medical and Endocrinology OPD of Jinnah Hospital Lahore A total of 90 type 2 diabetics of both genders were recruited using nonprobability purposive sampling. Patients were randomized into 3 groups; 30 in each group. Group 1 received Metformin IR 1000 mg twice daily; group 2 received metformin XR 1000mg twice daily; and group 3 received metformin XR 500 mg twice daily, for a period of three months. HbA1c was done at baseline and after three months of therapy along with fasting blood sugars and random blood sugars weekly. Results: The mean age of patients was 46+-9 years, with 54% being males and 46% being females. There was a 1% reduction in HbA1c in group 1, 0.7% reduction in group 2 and only 0.4% reduction in group 3. Similarly, all three therapies were equally effective in reducing blood sugar fasting and blood sugar random at three months. Side effects namely diarrhoea, dyspepsia and flatulence were greatest with Metformin IR (40%) but less than half with Metformin XR at equivalent dose and negligible at half the dose. Conclusions: All three Metformin groups were effective in reduction of HbA1C and glycaemic control clinically and there is no statistical difference in HbA1c reduction

    Psychiatric and behavioral side effects (PBSEs) are common, undesirable effects associated with antiepileptic drug (AED) use. The objective of the study was to compare the PBSE profiles of older and newer AEDs in a large specialty practice-based sample of patients diagnosed with epilepsy. As part of the Columbia and Yale AED Database Project, we reviewed patient records including demographics, medical history, AED use, and side effects for 4085 adult patients (age: 18 years) newly started on an AED regimen. Psychiatric and behavioral side effects were determined by patient or physician report in the medical record, which included depressive mood, psychosis, anxiety, suicidal thoughts, irritability, aggression, and tantrum. Significant non-AED predictors of PBSE rate were first determined from 83 variables using logistic regression. Predictors were then controlled for in the comparison analysis of the rate of PBSEs and intolerable PBSEs (PBSEs that led to dosage reduction or discontinuation) between 18 AEDs. Psychiatric and behavioral side effects occurred in 17.2% of patients and led to intolerability in 13.8% of patients. History of psychiatric condition(s), secondary generalized seizures, absence seizures, and intractable epilepsy were associated with increased incidence of PBSE. Levetiracetam (LEV) had the greatest PBSE rate (22.1%). This was statistically significant when compared with the aggregate of the other AEDs (P<0.001, OR=6.87). Levetiracetam was also significantly (P<0.001) associated with higher intolerability rate (17.7%), dose decreased rate (9.4%), and complete cessation rate (8.3%), when compared with the aggregate of the other AEDs. Zonisamide (ZNS) was also significantly associated with a higher rate of PBSE (9.7%) and IPBSE (7.9%, all P<0.001). On the other hand, carbamazepine (CBZ), clobazam (CLB), gabapentin (GBP), lamotrigine (LTG), oxcarbazepine (OXC), phenytoin (PHT), and valproate (VPA) were significantly associated with a decreased PBSE

Our results indicate that γBCG induces long-term training of innate immunity in vitro. In vivo, γ......BCG vaccination is associated with a reduced mortality from nonmycobacterial infections. This is likely to be mediated by a combination of innate-immune memory ("trained immunity") and heterologous effects on adaptive immunity. As such, BCG could be used to boost host immunity...

    The acute cardiovascular side effects of iopamidol, metrizamide, and amidotrizoate during coronary arteriography and left ventriculography have been compared in anesthetized closed-chest dogs. The influence of these contrast media on hemodynamics, coronary circulation, ECG and physicochemical properties of coronary sinus blood were evaluated. Following intracoronary injection, iopamidol and metrizamide cause positive inotropism while amidotrizoate initially induces cardiodepression. All contrast solutions lead to marked increase of myocardial blood flow. Electrocardiographic changes are greater after amidotrizoate. A fall of cationic content in coronary sinus blood is seen after each contrast medium. Amidotrizoate leads to more decrease of potassium and both ionized and total calcium. Increase of osmolality and hydrogen ionic content is greater after amidotrizoate than after iopamidol and metrizamide. Following left ventricular injection, marked peripheral vasodilation, as seen after amidotrizoate, does not occur after low osmolality compounds. There are no significant differences between iopamidol and metrizamide in spite of the slightly higher osmolality of the former. Thus, both contrast materials should be equivalent with respect to their acute cardiovascular side effects under clinical conditions. Advantages of low osmolality radiological contrast media are discussed.

    Objective. Hypertension is the largest threat to patient health and a burden to health care systems. Despite various options, 30% of patients do not respond sufficiently to medical treatment. Mechanoreceptors in the aortic arch relay blood pressure (BP) levels through vagal nerve (VN) fibers to the brainstem and trigger the baroreflex, lowering the BP. Selective electrical stimulation of these nerve fibers reduced BP in rats. However, there is no technique described to localize and stimulate these fibers inside the VN without inadvertent stimulation of non-baroreceptive fibers causing side effects like bradycardia and bradypnea. Approach. We present a novel method for selective VN stimulation to reduce BP without the aforementioned side effects. Baroreceptor compound activity of rat VN (n = 5) was localized using a multichannel cuff electrode, true tripolar recording and a coherent averaging algorithm triggered by BP or electrocardiogram. Main results. Tripolar stimulation over electrodes near the barofibers reduced the BP without triggering significant bradycardia and bradypnea. The BP drop was adjusted to 60% of the initial value by varying the stimulation pulse width and duration, and lasted up to five times longer than the stimulation. Significance. The presented method is robust to impedance changes, independent of the electrode's relative position, does not compromise the nerve and can run on implantable, ultra-low power signal processors.

    Recent reviews of the benefits and risks associated with electroconvulsive therapy (ECT) have often reported mixed and conflicting results. Although there are very few qualitative studies on ECT, qualitative research offers the advantage of in-depth explorations into how people perceive and experience ECT. The objective of this qualitative study was to explore women's experiences and perceptions of the benefits and side effects associated with having ECT. The authors used narrative inquiry and in-depth interviews to obtain nine women's accounts and stories of ECT, focusing particularly on their accounts of perceived benefits and side effects associated with ECT. Qualitative thematic analysis of the interviews with nine women resulted in four main themes emerging from the interviews: "it's sort of like housecleaning," "I don't remember the wedding," made me stupider," and "putting them in a cage with a bear." Three of the women were able to articulate some perceived benefit arising from ECT, although these women also acknowledged the benefits did not last more than two weeks. The majority of women complained of significant and persistent autobiographical memory loss, cognitive deficits, and fear of the procedure.

  10. Self-Limited Kleptomania Symptoms as a Side Effect of Duloxetine

    Full Text Available Introduction. Impulse control disorders (ICDs have been described as a side effect of dopamine agonists, frequently used in neurodegenerative conditions affecting the nigrostriatal pathway. Serotonin-norepinephrine reuptake inhibitors (e.g., duloxetine have dose-dependent differential affinity for monoaminergic transporters, inhibiting the dopamine transporter at higher doses, thus increasing availability of synaptic dopamine, with the potential for similar impulse control side effects. Case Presentation. A 19-year-old Asian-American female with a history of depression developed new-onset stealing behaviors after an increase in her dose of duloxetine from 60 mg to 90 mg; she described these actions as “compulsive” and irresistible, later experiencing either relief or guilt, features compatible with an ICD. Her symptoms eventually subsided with continued use of 90 mg of duloxetine. Discussion. To the knowledge of the authors, this is the first report of a patient developing new-onset ICD behaviors after being placed on a higher dose of duloxetine, which can inhibit the dopamine transporter and cause difficulty with impulse control. The self-resolving nature of the symptoms may result from compensatory upregulation of dopamine transporters, increasing reuptake of dopamine. Asian populations may be at a higher risk due to the frequent occurrence of CYP2D6 polymorphisms, which decrease the conversion of duloxetine to its inactive metabolites.

    The trading of emission allowances is an important market instrument in climate policy. However, the inclusion of certain branches of industry in the trading system not only provides incentives for emission reduction, it also entails unwanted side effects. Thus, the objective of the present study is to identify such side effects-positive and negative-by examining the potential impact of waste management inclusion in the European Union Emissions Trading Scheme (EU ETS). Desk research was supplemented with qualitative and quantitative empirical analysis (based on expert interviews and a questionnaire) in order to analyse the related perceptions and expectations of actors and stakeholders. The impact of waste management inclusion in the EU ETS is analysed in terms of the following three areas: (i) costs and cost pass-through, (ii), competitiveness and market position, and (iii) carbon leakage. Concerning expectations in the area of costs, both the interviewed experts and the practitioners surveyed thought that costs were likely to increase or that they could be passed on to customers. However, experts and practitioners differed with respect to the possibility of carbon leakage. Clearly, increased knowledge of the possible impact arising from inclusion of the waste sector in the EU ETS would enable managers to become more proactive and to manage waste streams and treatment options more economically.

    Chemotherapy used for cancer treatment, due to the lack of specificity of drugs, is associated to various damaging side effects that have severe impact on patients' quality of life. Over the past 30 years, increasing efforts have been placed on optimizing chemotherapy dosing with the main goal of increasing antitumor efficacy while reducing drug-associated toxicity. A novel research shows that stem cells may act as a reservoir for the anticancer agent, which will subsequently release some of the drug's metabolites, or even the drug in its original form, in vicinity of the cancer cells. These cells may play a dual role in controlling drug toxicity depending on their capacity to uptake and release the chemotherapeutic drug. In our study, we show that Dental Pulp Stem Cells DPSCs are able to rapidly uptake Paclitaxel PTX, and to release it in the culture medium in a time-dependent manner. This resulting conditioned culture medium is to be transferred to breast cancer cells, the MCF-7. By applying Confocal Raman Microscopy, the anticancer drug uptake by the MCF-7 was measured. Surprisingly, the cancer cells -without any direct contact with PTX- showed a drug uptake. This proves that the stem cells carried and delivered the anticancer drug without its modification. It could be a revolution in chemotherapy to avoid the drug's side effects and increase its efficacy.

    Objective: To investigate the perceptions of health status and depression among Renal Transplant Recipients (RTRs). Stydy Design: A longitudinal research design was used. Methods: Recipients’ perceived health status (PHS) was measured by a self-developed questionnaire that reflected the symptom severity and frequency of common immunosuppressant side effects. Depression levels were assessed using Beck Depression Inventory B.D.I II) .The sample population comprised of RTRs with a successful and healthy renal transplant recruited from private and government sector renal units in Lahore, Pakistan. Results: Recipients with poorer perceptions of health status tend to be more depressed as indicated by significant negative correlations between PHS and depression. However, further regression analysis found both constructs as significant predictors of each other, raising a question of causal direction. A cross lagged correlation analysis indicated that PHS appears to be a stronger predictor of depression comparatively. Most recipients tend to have positive perceptions of their health status (M = 30.84, S.D = 3.64) with minimum to moderate level of depression (M = 9.50, S.D = 4.00), It is found that a positive perception of health status is associated with lowered depression. Conclusion: Most recipients’ with a healthy kidney transplant tend to report a positive perception of their health status despite adverse medication side effects. However, the perceived health status is significantly associated with consequent feeling of depression. The study confirms the efficacy and positive health outcomes of renal transplantation in Pakistan. (author)

    2008-05-01

    Full Text Available Abstract Introduction Oxycodone is a widely-used semisynthetic opioid analgesic that has been used for over eighty years. Oxycodone is known to cause side effects such as nausea, pruritus, dizziness, constipation and somnolence. As far as we are aware cholestatic hepatitis as a result of oxycodone use has not been reported so far in the world literature. Case presentation A 34-year-old male presented with cholestatic jaundice and severe pruritus after receiving oxycodone for analgesia post-T11 vertebrectomy. Extensive laboratory investigations and imaging studies did not reveal any other obvious cause for his jaundice and a liver biopsy confirmed canalicular cholestatis suggestive of drug-induced hepatotoxicity. The patient's symptoms and transaminases normalised on withdrawal of oxycodone confirming that oxycodone was the probable cause of the patient's hepatotoxicity. Conclusion We conclude that cholestatic hepatitis is possibly a rare side effect of oxycodone use. Physicians should be aware of the possibility of this potentially serious picture of drug-induced hepatotoxicity.

    Side effects and complications of the application of partial ileal bypass used for dislipidemia were analyzed in 162 patients with atherosclerosis. It was shown, that the partial ileal bypass operation could lead to the development of series of undesirable side effects such as diarrhea, hypovitaminosis B12, off-state intestine enteritis. The application of modification of partial ileal bypass such as formation of ileo-ileoanastomosis 5-6 cm long near ileocecal valve with the maintenance of its functions disposed the diarrhea and minimized the risk of the development of hypovitaminosis B12 after operation. It is possible to prevent the development of enteritis of off-state loop of the small intestine by using microanastomosis between off-state and functioning iliac intestine. The partial ileal bypass operation didn't influence on body weight, wouldn't increase the risk of stone formation in the gallbladder and kidneys. The risk of the development of hypovitaminosis B12 is minimal after operation.

    Highlights: ► A new analytical equation to model the end effect braking force of SLIM is derived. ► Equations for efficiency, power factor and output thrust are analytically derived. ► The effect of design variables on the performance of the motor is analyzed. ► An optimization method is employed to minimize the end effect braking force (EEBF). ► The results show that EEBF is minimized by appropriate selection of motor parameters. - Abstract: Linear induction motors have been widely employed in industry because of their simple structure and low construction cost. However, they suffer from low efficiency and power factor. In addition, existence of so called end effect influences their performance especially in high speeds. The end effect deteriorates the performance of the motor by producing braking force. So, in this paper, by using Duncan equivalent circuit model, a new analytical equation is proposed to model end effect braking force. Employing the proposed equation and considering all phenomena involved in the single-sided linear induction motor, a simple design procedure is presented and the effect of different design variables on the performance of the motor is analyzed. A multi-objective optimization method based on genetic algorithm is introduced to maximize efficiency and power factor, as well as to minimize the end effect braking force, simultaneously. Finally, to validate the optimization results, 2D finite element method is employed.

    Martensitic transition is a solid-state phase transition involving cooperative movement of atoms, mostly studied in metallurgy. The main characteristics are low transition barrier, ultrafast kinetics, and structural reversibility. They are rarely observed in molecular crystals, and hence the origin and mechanism are largely unexplored. Here we report the discovery of martensitic transition in single crystals of two different organic semiconductors. In situ microscopy, single-crystal X-ray diffraction, Raman and nuclear magnetic resonance spectroscopy, and molecular simulations combined indicate that the rotating bulky side chains trigger cooperative transition. Cooperativity enables shape memory effect in single crystals and function memory effect in thin film transistors. We establish a molecular design rule to trigger martensitic transition in organic semiconductors, showing promise for designing next-generation smart multifunctional materials.

    2014-01-01

    We reviewed the Chinese and English literature for the efficacy and safety data of valsartan monotherapy or combination therapy in Chinese hypertensive patients. According to the data of ten randomized controlled trials, valsartan monotherapy was as efficacious as another angiotensin receptor blocker or other classes of antihypertensive drugs, excepting the slightly inferior diastolic blood pressure-lowering effect in comparison with calcium channel blockers. According to the data of six randomized controlled trials, valsartan combination, with hydrochlorothiazide, amlodipine, or nifedipine gastrointestinal therapeutic system, was more efficacious than monotherapy of valsartan, amlodipine, or nifedipine gastrointestinal therapeutic system. According to these trials, valsartan had an acceptable tolerability, regardless of whether it was used as monotherapy or in combination therapy. Nonetheless, several rare side effects have been reported, indicating that it should still be used with caution. This is of particular importance given that there are millions of hypertensive patients, worldwide, currently exposed to the drug. PMID:24403822

    2007-01-01

    Increased utilization of iodinated contrast media may be associated with increased incidence of adverse events. The most important side effects include contrast-induced nephropathy, anaphylactoid reaction, thyrotoxicosis, and extravasation. In patients with moderate renal dysfunction, saline hydration and reduction of contrast media volume are recommended. No regime to prevent anaphylactoid reactions has yet proven to be efficient. If subclinical hyperthyroidism has been determined, prophylaxis with sodium perchlorate is advised. Contrast-induced nephropathy is commonly transient and needs to be followed over time. Mild general anaphylactoid reactions may be treated with antihistaminic drugs and corticosteroids. Furthermore the choice of the X-ray contrast media might influence the risk of any adverse effects.

    The better knowledge of the mechanisms of nuclear incidents and lessons learned from accidents in the recent past to improve the effectiveness of measures taken following a nuclear accident exposure to fallout of radioactive iodine isotopes. Thus, immediate, passive measures, such as containment, and stopping consumption of contaminated products are paramount. The earliest possible administration of stable iodine as potassium iodide (KI) reduces significantly (up to 90% if taken at the same time of the accident) thyroid radioactive contamination. These tablets should be given in priority to children and pregnant women. The side effects are minor. KI is not recommended for persons aged over 60 years, or for adults suffering from cardiovascular disorders. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Objective: To evaluate the protective role of a mixture of honey bee products (honey, royal jelly and pollen grains against the genotoxicity induced by the anticancer drug cyclophosphamide (CP. Methods: The study included chromosomal aberration analysis in mice bone marrow cells, induction of morphological sperm abnormalities, DNA fragmentation and histopathological changes induced in liver cells of mice. CP was injected intraperitoneally at the dose of 20 mg/ kg body weight. The mixture of honey bee products was administrated orally for different periods of time 5, 10 and 15 days with a dose exactly equivalent to the daily intake of human beings. Results: The results revealed that honey mixture ameliorated the genotoxic side effects of CP. For chromosomal aberrations the percentage reached 25.20 ± 1.30 for CP treated group, while it reached half of that value 12.30 ± 0.54 in CP-group pretreated with honey mixture for 15 days. Breaks, fragments and multiple aberrations were the most pronounced types of aberrations induced after CP treatment and honey mixture reduced these types of abnormalities. CP induced significant percentage of sperm abnormalities 8.52 ± 0.17 compared to control 3.10 ± 0.10. The percentage of sperm abnormalities reached nearly to the control value in CP- mice treated with honey mixture for 15 days. Honey also reduced the incidence of liver DNA damage induced by CP. The results also indicated that CP had a marked damaging effect on liver tissue including severe dilatation, congestion of main blood vessels and massive infiltration of inflammatory cells with irregular general pattern of the tissue. These effects were greatly ameliorated by using oral administration of honey mixture for different periods of time. Conclusions: The results concluded that honey bee mixture can be used as chemopreventive agent for minimizing the genotoxic side effects of the anticancer drug CP and open the field for its use in many applications.

    Whereas the efficacy of the newer antiepileptic drugs (AEDs) is well established, there remain questions regarding their cognitive side effects. Therefore, we performed a comparative open randomized trial with TPM and TGB as add-on therapy, with particular consideration of cognition, mood, and health-related quality of life (HRQOL). Forty-one patients with refractory epilepsy were randomly assigned to one of the two treatment groups (TPM vs TGB) and received neuropsychological testing at baseline (T1), after titration (3 months, T2), and during the maintenance phase (another 3 months, T3). Tests included measures of intelligence, attention, working memory, episodic memory, language, and self-report questionnaires regarding mood and HRQOL. Twenty patients (8 TPM, 12 TGB) discontinued the trial for different reasons (no group difference). Seizure outcome (intention-to-treat analysis) was comparably good in both groups (8.1% seizure free, 29.7% seizure reduction>50%). From baseline to after the titration paired sample t tests revealed significant deterioration in verbal fluency, language comprehension, working memory, and visual block tapping under TPM and a deterioration in verbal memory (delayed free recall) in the TGB group. These functions remained stable in the maintenance phase. Self-report measures initially indicated concerns about AED side effects in both groups and concerns about worse cognitive functioning and depression under TPM. In the maintenance phase the TGB group reported feeling a lack of energy, whereas patients on TPM demonstrated improvement on all QOLIE scales on a descriptive level. This study demonstrates the comparable efficacy of TPM and TGB. Consistent with previous reports, TPM but not TGB appears to be associated with persistent negative cognitive side effects on frontal lobe-associated functions, the degree of which may be estimated by the fact that this effect was observed with a very small sample size. In contrast, in patients taking

In experimental vaccination trials with rainbow trout (Oncorhynchus mykiss) using a DNA-vaccine encoding the viral glycoprotein of viral...... haemorrhagic septicaemia virus (VHSV), non-specific as well as specific immune mechanisms seemed to be delayed at low temperature. At five weeks post vaccination fish kept at 5C had no detectable response of neutralising antibodies while two thirds of the fish kept at 15C had sero-converted. While protective...... immunity was still established at both temperatures, specificity analysis suggested that protection at the lower temperature was mainly due to non-specific innate antiviral mechanisms, which appeared to last longer at low temperature. This was presumably related to a prolonged persistence of the vaccine...

    We fabricate planar graphene field-effect transistors with self-aligned side-gate at 100 nm from the 500 nm wide graphene conductive channel, using a single lithographic step. We demonstrate side-gating below 1 V with conductance modulation of 35% and transconductance up to 0.5 mS/mm at 10 mV drain bias. We measure the planar leakage along the SiO{sub 2}/vacuum gate dielectric over a wide voltage range, reporting rapidly growing current above 15 V. We unveil the microscopic mechanisms driving the leakage, as Frenkel-Poole transport through SiO{sub 2} up to the activation of Fowler-Nordheim tunneling in vacuum, which becomes dominant at higher voltages. We report a field-emission current density as high as 1 μA/μm between graphene flakes. These findings are important for the miniaturization of atomically thin devices.

    Radioiodine treatment is considered to be the treatment of choice in benign thyroid diseases because of its very low side effects. Real and hypothetic risks and side effects have to be differentiated. Both may occur early and late after the treatment. Radioiodinethyroiditis in small volumes at high doses is very rare. Exacerbation of a thyroid storm (0.34%) as well as local compressions accompanied with reactive edema of the thyroid are early real side effects of radioiodine treatment. Late real side effects are failure of treatment (7-30% of thyrotoxicosis) and induction of hypothyroidism (4-20% of functional autonomy and increasing frequency in Graves' diseases with time). Late hypothetic risks are somatic (1-9/10000 bis 1-9/100000) or genetic (1-9/100000). An early risk might be the misdiagnosis of an additional thyroid carcinoma. (orig.).

Recent studies have pointed out their effect on weight gain and increased visceral adiposity as they induce metabolic syndrome. Patients receiving SGAs often need to be treated with other substances to counteract metabolic side effects. In this paper, we point out the possible protective effect of add-on melatonin treatment in preventing, mitigating, or even reversing SGAs metabolic effects, improving quality of life and providing safer long-term treatments in pediatric patients. Melatonin is an endogenous indolamine secreted during darkness by the pineal gland; it plays a key role in regulating the circadian rhythm, generated by the suprachiasmatic nuclei (SCN of the hypothalamus, and has many other biological functions, including chronobiotic, antioxidant and neuroprotective properties, anti-inflammatory and free radical scavenging effects, and diminishing oxidative injury and fat distribution. It has been hypothesized that SGAs cause adverse metabolic effects that may be restored by nightly administration of melatonin because of its influence on autonomic and hormonal outputs. Interestingly, atypical anti-psychotics (AAPs can cause

    Full Text Available BACKGROUND: Fingolimod (FTY-720 has shown efficacy in relapsing multiple sclerosis (MS, while some side effects of this drug have been recognized that the most important is cardiovascular side effects. The aim of this study was to evaluate the cardiovascular side effects of FTY-720. However, the effect of fingolimod on cardiac has not been well recognized. This study was designed to evaluate the cardiovascular side effects of fingolimod in relapsing-remitting multiple sclerosis (RRMS patient in an Iranian population. METHODS: This prospective clinical trial study was performed on 200 RRMS patients. The patients received a single daily oral dose of fingolimod 0.5 mg. During the first 6 hours after the first fingolimod dose, the patients’ vital signs and electrocardiographic traces were continuously monitored. Moreover, the patients followed up over 6 months after receiving fingolimod. RESULTS: The results showed that pulse rate (P < 0.001, systolic blood pressure (BP (P < 0.001, and diastolic BP (P < 0.001 were decreased significantly during 6 hours after receiving the first dose of fingolimod. The most reduction in vital sign was observed in 3 hours. Arrhythmia, bradycardia, and dizziness were the other complications of fingolimod, which were detected in our study. CONCLUSION: All the side effects such as hypotension and bradycardia were happened in first 3 hours after receiving the fingolimod. Indeed, we advise clinicians to monitor the patients for first 6 hours after initiation of fingolimod to decrease worse side effects

    This is a study that updates earlier research on the influence of a front passenger on the risk for severe driver injury in near-side and far-side impacts. It includes the effects of belt use by the driver and passenger, identifies body regions involved in driver injury, and identifies the sources for severe driver head injury. 1997-2015 NASS-CDS data were used to investigate the risk for Maximum Abbreviated Injury Scale (MAIS) 4 + F driver injury in near-side and far-side impacts by front passenger belt use and as a sole occupant in the driver seat. Side impacts were identified with GAD1 = L or R without rollover (rollover ≤ 0). Front-outboard occupants were included without ejection (ejection = 0). Injury severity was defined by MAIS and fatality (F) by TREATMNT = 1 or INJSEV = 4. Weighted data were determined. The risk for MAIS 4 + F was determined using the number of occupants with known injury status MAIS 0 + F. Standard errors were determined. Overall, belted drivers had greater risks for severe injury in near-side than far-side impacts. As a sole driver, the risk was 0.969 ± 0.212% for near-side and 0.313 ± 0.069% for far-side impacts (P impacts. The risk was 2.17 times greater with an unbelted passenger (NS). The driver's risk was 0.782 ± 0.431% with an unbelted passenger and 0.361% ± 0.114% with a belted passenger in far-side impacts. The risk was 1.57 times greater with an unbelted passenger (P impacts, the leading sources for AIS 4+ head injury were the left B-pillar, roof, and other vehicle. For far-side impacts, the leading sources were the other occupant, right interior, and roof (8.5%). Seat belt use by a passenger lowered the risk of severe driver injury in side impacts. The reduction was 54% in near-side impacts and 36% in far-side impacts. Belted drivers experienced mostly head and thoracic AIS 4+ injuries. Head injuries in the belted drivers were from contact with the side interior and the other occupant, even with a belted passenger.

    The aim of this study was to compare the side-effects of glyphosate to the parasitoid Telenomus remus Nixon (Hymenoptera: Platygastridae) when parasitoids were exposed to this chemical at the pupal (inside host eggs) and adult stages. Bioassays were conducted under laboratory conditions according to the International Organization for Biological Control (IOBC) standard methods for testing side-effects of pesticides to egg parasitoids. Different glyphosate-based pesticides (Roundup Original®, Roundup Ready®, Roundup Transorb®, Roundup WG®, and Zapp Qi®) were tested at the same acid equivalent concentration. Treatments were classified following the IOBC toxicity categories as (1) harmless, (2) slightly harmful, (3) moderately harmful, and (4) harmful. When tested against T. remus adults, Roundup Original®, Roundup Ready®, Roundup Transorb®, and Roundup WG® reduced parasitism 2 days after parasitoid emergence, being classified as slightly harmful. Differently, when tested against T. remus pupae, all tested glyphosate-based products did not differ in their lethal effect and therefore did not reduce T. remus adult emergence or parasitism capacity, being classified as harmless. However, differences on sublethal toxicity were found. Parasitism of individuals emerging from parasitized eggs sprayed at the pupal stage of T. remus with Zapp Qi® was lower compared to control, but parasitism was still higher than 66%, and therefore, Zapp Qi® was still classified as harmless. In conclusion, all tested glyphosate-based products can be used in agriculture without negative impact to T. remus as none was classified as harmful or moderately harmful to this parasitoid when exposure occurred at the pupal or adult stages.

    Corticosteroids currently are the most effective pharmacological treatment available to control heaves in horses. Systemically administered corticosteroids have been shown to alter immune response in horses, humans, and other species. Aerosolized administration theoretically minimizes systemic adverse effects, but the effect of inhaled corticosteroids on immune function has not been evaluated in horses. To evaluate the effects of prolonged administration of inhaled fluticasone on the immune system of heaves-affected horses. Heaves-affected horses were treated with inhaled fluticasone (n = 5) for 11 months or received environmental modifications only (n = 5). Prospective analysis. Clinical parameters and CBC, lymphocyte subpopulations and function, and circulating neutrophil gene expression were sequentially measured. Primary and anamnestic immune responses also were evaluated by measuring antigen-specific antibodies in response to vaccination with bovine viral antigen and tetanus toxoid, respectively. No clinical adverse effects were observed and no differences in immune function were detected between treated and untreated horses. The treatment of heaves-affected horses with inhaled fluticasone at therapeutic dosages for 11 months has no significant detectable effect on innate and adaptive (both humoral and cell-mediated) immune parameters studied. These results suggest that prolonged administration of fluticasone would not compromise the systemic immune response to pathogens nor vaccination in adult horses.

    Hypopituitary dwarf mice demonstrate advantages of longevity, but little is known of their colon development and intestinal immunity. Herein we found that Ames dwarf mice have shorter colon and colonic crypts, but larger ratio of mesenteric lymph nodes (MLNs) over body weight than age-matched wild type (WT) mice. In the colonic lamina propria (cLP) of juvenile Ames mice, more inflammatory neutrophils (Ā: 0.15% vs. 0.03% in WT mice) and monocytes (Ā: 7.97% vs. 5.15%) infiltrated, and antigen presenting cells CD11c+ dendritic cells (Ā: 1.39% vs. 0.87%), CD11b+ macrophages (Ā: 3.22% vs. 0.81%) and gamma delta T (γδ T) cells (Ā: 5.56% vs. 1.35%) were increased. In adult Ames dwarf mice, adaptive immune cells, such as IL-17 producing CD4+ T helper (Th17) cells (Ā: 8.3% vs. 4.7%) were augmented. In the MLNs of Ames dwarf mice, the antigen presenting and adaptive immune cells also altered when compared to WT mice, such as a decrease of T-regulatory (Treg) cells in juvenile Ames mice (Ā: 7.7% vs.10.5%), but an increase of Th17 cells (Ā: 0.627% vs.0.093%). Taken together, these data suggest that somatotropic signaling deficiency influences colon development and intestinal immunity.
