    Full Text Available Objective: To study the relationship of serum sphingosine 1-phosphate (S1P and heparin cofactor II (HCII levels with vasoactive substances and cytokines in patients with cerebral vascular restenosis after stent implantation. Methods: 52 patients who received cerebrovascular stent implantation and developed restenosis in our hospital between May 2012 and December 2015 were collected as observation group, and 40 healthy patients with cerebrovascular stent implantation who had re-examination in our hospital during the same period were selected as control group. ELISA method was used to detect serum S1P and HC-II levels as well as vasoactive substance and inflammatory factor contents. Spearman correlation analysis was used to evaluate the relationship of serum S1P and HC-II levels with vasoactive substances and inflammatory factors. Results: Serum S1P and HC-II levels of observation group were lower than those of control group (P<0.05; serum vasoactive substances endothelin (ET, angiotensin II (AngII and thromboxane B2 (TXB2 contents of observation group were higher than those of control group while nitric oxide (NO content was lower than that of control group (P<0.05; serum inflammatory factors hypersensitive C-reactive protein (hs-CRP, interleukin-1 (IL-1, IL-6, IL-8 and IL-11 contents of observation group were higher than those of control group (P<0.05. Serum S1P and HC-II levels in patients with cerebral vascular restenosis after stent implantation were directly correlated with vasoactive substance and inflammatory factor contents. Conclusion: Serum S1P and HC-II levels decrease in patients with cerebral vascular restenosis after stent implantation, and it is an important cause of cerebral vascular dysfunction and systemic inflammatory response.

    In 12 patients suffering from systemic sclerosis (SSc) the influence of autogenic training on the plasma level of the neuropeptides substance P and vasoactive intestinal peptide (VIP) was studied. Compared with healthy controls the SSc patients exhibited significantly elevated levels of substance P (mean +/- SD: 7.1 +/- 3.2 pmol/l vs 1.6 +/- 1.6 pmol/l). Apart from variations the VIP plasma concentration did not significantly differ from that in healthy controls (mean +/- SD 10.7 +/- 7.1 pmol/l versus 12.0 +/- 5.3 pmol/l). Autogenic training did not bring about any significant changes in the plasma levels of neuropeptides.

    Victimization by and perpetration of domestic violence are associated with co-occurring mental and substance use disorders. This study used data from the National Survey of Substance Abuse Treatment Services to examine differences in organizational factors, treatment approaches offered, and client-level factors among 13,342 substance abuse treatment facilities by whether or not they offered domestic violence services. Only 36% of the facilities offered domestic violence services. Those that offered such services were more likely than those that did not to treat clients with co-occurring disorders. Principal-components analysis reduced eight treatment approaches to two factors: psychosocial services and traditional substance abuse services. Regression models indicated that the frequency with which psychosocial services were offered depended on the percentage of clients with co-occurring disorders who were being treated in the facility and whether or not that facility offered domestic violence services. Specifically, facilities that did not offer domestic violence services and that had a high percentage of clients with co-occurring disorders were more likely to offer psychosocial services than facilities that offered domestic violence services. A larger proportion of facilities offering domestic violence services offered traditional substance abuse treatment services, compared with facilities not offering domestic violence services, but this relationship was not contingent on the percentage of clients with co-occurring disorders at each facility. Improved efforts should be made to tailor treatments to accommodate the links between domestic violence, mental disorders, and substance abuse.

    Neuropeptide Y (NPY) is widely distributed in the sympathetic nervous system, where it is colocalized with norepinephrine. The authors report here that NPY-immunoreactive neurons are also abundant in three cranial parasympathetic ganglia, the otic, sphenopalatine, and ciliary, in the rat measured by radioimmunoassay. High-performance liquid chromatographic analysis of the immunoreactive material present in the otic ganglion indicates that this material is very similar to porcine NPY and indistinguishable from the NPY-like immunoreactivity present in rat sympathetic neurons. These findings raise the possibility that NPY acts as a neuromodulator in the parasympathetic as well as the sympathetic nervous system. In contrast to what had been observed for sympathetic neurons, NPY-immunoreactive neurons in cranial parasympathetic ganglia do not contain detectable catecholamines or tyrosine hydroxylase immunoreactivity, and many do contain immunoreactivity for vasoactive intestinal peptide and/or choline acetyltransferase. These findings suggest that there is no simple rule governing coexpression of NPY with norepinephrine, acetylcholine, or vasoactive intestinal peptide in autonomic neurons. Further, while functional studies have indicated that NPY exerts actions on the peripheral vasculature which are antagonistic to those of acetylcholine and vasoactive intestinal peptide, the present results raise the possibility that these three substances may have complementary effects on other target tissues

    Full Text Available Objective To observe the effect of Cordyceps sinensis mycelium on serum vasoactive intestinal peptide (VIP and substance P (SP in mice with dysbacteriosis induced by antibiotics. Methods Forty-eight healthy SPF BALB/c mice were randomly divided into the normal control group (normal drink, the dysbacteriosis model group (induced by oral administration of 0.5 g/L ceftriaxone sodium, the natural recovery group (oral sterile water to replace antibiotic after reproduction of dysbacteriosis, and Cordyceps sinensis mycelium treatment group (treated by intragastric administration of Cordyceps sinensis mycelium. The feces were collected without contamination, and the change in intestinal bacterial number was observed with the plate dilution method. The volatile fatty acid was detected by chromatography. The serum VIP and SP contents were assayed with enzyme linked immunosorbent assay (ELISA. Results Compared with the normal control group, the numbers of probiotics, volatile fatty acids and serum VIP significantly decreased in the model group, while the serum SP markedly increased (P<0.01. Compared with the natural recovery group, the bacteria number, the quantities of volatile fatty acids and serum VIP significantly increased after the Cordyceps sinensis mycelium treatment, while the serum SP significantly decreased (P<0.01, P<0.05. Conclusion Cordyceps sinensis mycelium may effectively adjust the proportion of the probiotics in the mice with dysbacteriosis, and the mechanism is apparently related to alteration in the VIP and SP.

    Rett syndrome is associated with profound mental retardation and motor disability in girls. It has a characteristic clinical phenotype which includes abnormalities of the autonomic nervous system. Feeding impairment and severe constipation are two symptoms of this autonomic dysfunction. Substance P, an important peptide in the autonomic nervous system, is decreased in the cerebrospinal fluid of Rett syndrome. We have demonstrated that substance P immunoreactivity is significantly decreased in Rett syndrome brain-stem and may be related to the autonomic dysfunction. In this study, we have continued the investigation of substance P in the enteric nervous system. We immunohistochemically examined the normal developing bowel in 22 controls (ages, 14 gestational weeks to 31 years) using formalin fixed tissue, with antibodies to substance P, tyrosine hydroxylase and vasoactive intestinal peptide. We compared the immunoreactivity of normal controls with 14 cases of Rett syndrome (ages, 5-41 years) and observed that the expression of substance P, tyrosine hydroxylase and vasoactive intestinal peptide immunoreactivity in the bowel in Rett syndrome was not significantly different from that of controls. This suggests that the feeding impairment and constipation in Rett syndrome relate to dysfunction of the autonomic nervous system originating outside of the bowel, in the brain-stem, as suggested by our previous study.

    Being a nurse in an intensive care unit entails caring for seriously ill patients. Vasoactive drugs are one of the tools that are used to restore adequate circulation. Critical care nurses often manage and administer these potent drugs after medical advice from physicians. To describe the experiences of critical care nurses learning to manage vasoactive drugs, and to highlight the competence required to manage vasoactive drugs. Twelve critical care nurses from three hospitals in Sweden were interviewed. Qualitative content analysis was applied. The theme "becoming proficient requires accuracy, practice and precaution" illustrated how critical care nurses learn to manage vasoactive drugs. Learning included developing cognitive, psychomotor, and effective skills. Sources for knowledge refers to specialist education combined with practical exercises, collegial support, and accessible routine documents. The competence required to manage vasoactive drugs encompassed well-developed safety thinking that included being careful, in control, and communicating failures. Specific skills were required such as titrating doses, being able to analyse and evaluate the technological assessments, adapting to the situation, and staying calm. Learning to manage vasoactive drugs requires a supportive introduction for novices, collegial support, lifelong learning, and a culture of safety. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Vasoactive intestinal peptide and secretin increased cellular cAMP and pepsinogen secretion in dispersed chief cells from guinea pig gastric mucosa. With each peptide there was a close correlation between the dose-response curve for changes in cellular cAMP and that for changes in pepsinogen secretion. Vasoactive intestinal peptide- (10-28) and secretin- (5-27) had no agonist activity and antagonized the actions of vasoactive intestinal peptide and secretin on cellular cAMP and pepsinogen secretion. Studies of binding of 125 I-vasoactive intestinal peptide and of 125 -secretin indicated that gastric chief cells possess four classes of binding sites for vasoactive intestinal peptide and secretin and that occupation of two of these classes of binding sites correlates with the abilities of vasoactive intestinal peptide and secretin to increase cellular cAMP and pepsinogen secretion. What function, in any, is mediated by occupation by the other two classes of binding sites remains to be determined

    Vasoactive liabilities are typically assayed using wire myography, which is limited by its high cost and low throughput. To meet the demand for higher throughput in vitro alternatives, this study introduces a magnetic 3D bioprinting-based vasoactivity assay. The principle behind this assay is the magnetic printing of vascular smooth muscle cells into 3D rings that functionally represent blood vessel segments, whose contraction can be altered by vasodilators and vasoconstrictors. A cost-effective imaging modality employing a mobile device is used to capture contraction with high throughput. The goal of this study was to validate ring contraction as a measure of vasoactivity, using a small panel of known vasoactive drugs. In vitro responses of the rings matched outcomes predicted by in vivo pharmacology, and were supported by immunohistochemistry. Altogether, this ring assay robustly models vasoactivity, which could meet the need for higher throughput in vitro alternatives. PMID:27477945

  11. Clostridium difficile suppresses colonic vasoactive intestinal peptide associated with altered motility

    1995-01-01

    Full Text Available We investigated whether Clostridium difficile toxin alters colonic tissue levels of vasoactive intestinal peptide (VIP at the expense of changes in colonic motility in the isolated perfused rabbit left colon. Colonic inflammation was induced by the intracolonic administration of 10−8 M C. difflcile toxin. Strain gauge transducers were sewn onto the serosal surface of the colon to evaluate colonic motility. C. difflcile administration produced histologic changes consistent with epithelial damage. This was associated with an increased production of prostaglandin E2 and thromboxane B2. Tissue levels of VIP but not substance P were significantly reduced. This was associated with an increased number of contractions per minute and an average force of each colonic contraction. These results suggest that tissue levels of VIP are suppressed by C. difflcile and may participate in colonic dysmotility during active inflammation.

  17. Vasoactive drugs and the gut: is there anything new?

    Woolsey, Cheryl A; Coopersmith, Craig M

    2006-04-01

    Systemic changes in blood pressure and cardiac output induced by pressors and inotropes do not always correlate to improvements in regional perfusion. Since the gut is often referred to as the 'motor' of the systemic inflammatory response syndrome, the impact of vasoactive agents on splanchnic perfusion has theoretical importance. This review will highlight recent studies examining secondary effects of vasoactive agents on intestinal perfusion, metabolism, and barrier function. Norepinephrine has minimal impact on mesenteric blood flow although the combination of norepinephrine and dobutamine increases splanchnic blood flow in sepsis. Dopamine also increases mesenteric blood flow although this may be associated with negative hepatic energy balance at high does. Vasopressin and epinephrine both have negative effects on splanchnic blood flow. Newer inodilators levosimendan and olprinone preferentially improve mesenteric perfusion in animal models. Secondary effects of norepinephrine and dopamine on splanchnic perfusion are minor compared with their systemic effects. While vasopressin usage is increasing in the intensive care unit, caution should be used because of its adverse effects on gut perfusion. Experimental agents for the treatment of heart failure have beneficial gut-specific effects although the clinical significance of this is currently limited by their availability.

    We hypothesized that bioactive peptides might be released into the portal circulation and mediate pathophysiologic alterations accompanying small bowel obstruction. We studied this question in a subacute canine small bowel obstruction model using 50 percent diameter occlusion. Control animals underwent sham laparotomy. Vasoactive intestinal peptide (VIP), peptide YY, and gastrin were measured in portal and systemic plasma by specific radioimmunoassays at 24-hour intervals as the obstruction progressed to completion over 5 days. All peptides in both groups demonstrated portal and peripheral gradients. In control dogs, peptide concentrations did not change postoperatively but VIP increased markedly in obstructed dogs, demonstrating a median portal level of 95 pmol/liter at 96 hours compared with 31.5 pmol/liter in control animals. These portal VIP levels are known to cause hypersecretion and splanchnic vasodilation in experimental models. The release of vasoactive compounds such as VIP may mediate local pathophysiology in human small bowel obstruction. A similar explanation of the systemic effects is consistent with the known cardiopulmonary bioactivity of VIP.

    In normotensive conditions, it has been confirmed that S-nitrosothiols (RSNO), can interact with hydrogen sulfide (H 2 S) and create new substances with specific vasoactive effects. This interaction could also represent a new regulator signaling pathway in conditions of hypertension. Until now, these effects were studied only in normotensive rats, and they have not been carried out in humans yet. We investigated the vasoactive effects of the products of the H 2 S/S-nitrosoglutathione (S/GSNO) interaction in lobar arteries (LA) isolated from the nephrectomized kidneys of patients suffering from arterial hypertension and in renal arteries (RA) of spontaneously hypertensive rats (SHR). The changes in the isometric tension of pre-contracted arteries were evaluated. Acetylcholine-induced vasorelaxation of LA was reduced compared to the effect induced by an NO donor, sodium nitroprusside suggesting an endothelium dysfunction. While 1 μmol/L Na2S had a minimal effect on the vascular tone, the concentration 20 μmol/L evoked a slight vasorelaxation. GSNO at 0.1 μmol/L induced vasorelaxation, which was less pronounced compared to the effect induced by 1 μmol/L. The S/GSNO products (final concentration 0.1 μmol/L) prepared as the mixture of GSNO (0.1 μmol/L) + Na2S (1 μmol/L) induced a higher vasorelaxation compared to GSNO (0.1 μmol/L) alone only in the 5 th minute and without the differences in the speed. On the other hand, the S/GSNO products (final concentration 1 μmol/L) prepared as the mixture of GSNO (1 μmol/L) + Na2S (10 μmol/L) induced a higher and faster vasorelaxation compared to the effect induced by GSNO (1 μmol/L) alone. In RA of SHR this S/GSNO products induced similar vasorelaxation (higher and faster than GSNO) with involvement of HNO (partially) and cGMP as mediators. However, the products of the H 2 S/NO donor (DEA NONOate) manifested differently than S/GSNO indicating the unique interaction between GSNO and H 2 S. In this study, we confirmed

    Besides their importance for the vascular tone, vascular smooth muscle cells (VSMC) also contribute to pathophysiological vessel alterations. Various G-protein coupled receptor ligands involved in vascular dysfunction and remodeling can transactivate the epidermal growth factor receptor (EGFR) of VSMC, yet the importance of EGFR transactivation for the VSMC phenotype is incompletely understood. The aims of this study were (i) to characterize further the importance of the VSMC-EGFR for proliferation, migration and marker gene expression for inflammation, fibrosis and reactive oxygen species (ROS) homeostasis and (ii) to test the hypothesis that vasoactive substances (endothelin-1, phenylephrine, thrombin, vasopressin and ATP) rely differentially on the EGFR with respect to the abovementioned phenotypic alterations. In primary, aortic VSMC from mice without conditional deletion of the EGFR, proliferation, migration, marker gene expression (inflammation, fibrosis and ROS homeostasis) and cell signaling (ERK 1/2, intracellular calcium) were analyzed. VSMC-EGFR loss reduced collective cell migration and single cell migration probability, while no difference between the genotypes in single cell velocity, chemotaxis or marker gene expression could be observed under control conditions. EGF promoted proliferation, collective cell migration, chemokinesis and chemotaxis and leads to a proinflammatory gene expression profile in wildtype but not in knockout VSMC. Comparing the impact of five vasoactive substances (all reported to transactivate EGFR and all leading to an EGFR dependent increase in ERK1/2 phosphorylation), we demonstrate that the importance of EGFR for their action is substance-dependent and most apparent for crowd migration but plays a minor role for gene expression regulation.

    Numbers of novel psychoactive substances (NPS) have been rapidly increasing over the past few years, with unprecedented challenges on traditional drug control systems. The web has been involved in the promotion and knowledge dissemination of NPS, which are being presented online as safer/legal alternatives to illicit drugs. The physical, psychological and social harms associated with NPS have been studied so far mainly in Europe and other English speaking countries. The aim of this research is to provide knowledge on the provision of NPS information/purchase opportunities to Middle East customers, whilst monitoring the Internet in Arabic and Farsi. Web analysis/assessments were carried out in both Farsi and Arabic between 2011 and 2013. Sources were scrutinized with the help of different search engines, including Google Arabic and Google Persian, to carry out searches focusing on both NPS retailers' and social network websites. The research identified 45 NPS apparently offered for purchase online. Most of these products were of synthetic origin; a few herbal stimulants were identified as well. The pro drug websites were not here easily identified, being hidden behind other, unrelated, websites. Present results may constitute a public health challenge to be considered at both national and worldwide level. New legislative frameworks should also be encouraged in order to ensure a better response to the current threat posed by rapid emergence of these substances. Copyright © 2014 Elsevier B.V.

    Patients with cirrhosis display hypocontractility of splanchnic vessels because of dysregulation of vasoactive proteins, such as decreased effect of RhoA/ROCK and increased activity of β-Arrestin-2 and eNOS. However, it is unknown whether the dysregulation of vasoactive proteins is displayed in other vessels. We investigated whether expression of vasoactive proteins can be evaluated in gastric mucosa vessels. Biopsies from the gastric mucosa of 111 patients with cirrhosis were collected at three different centres and from 13 controls. Forty-nine patients had received TIPS. Portal pressure gradient was measured in 49 patients with TIPS and in 16 patients without TIPS. Biopsies from the antrum were conserved in formaldehyde for immunohistochemistry or shock-frozen for PCR and Western blot. The mucosal transcription of vascular markers (αSMA, CD31) was higher in cirrhotic patients than controls, which was confirmed by immunohistochemistry. On average, relative mucosal levels of RhoA and ROCK were lower, while β-Arrestin-2 levels were higher in cirrhotic patients compared to controls. Transcriptional levels of eNOS increased with presence of ascites and grade of oesophageal varices. Patients with TIPS showed less pronounced markers of vascular dysfunction in gastric mucosa. This is the first evidence that the expression of vasoactive proteins in mucosa from the gastric antrum of patients with cirrhosis reflects their vascular dysfunction and possibly changes after therapeutic interventions. © 2014 John Wiley & Sons A/S.

    Full Text Available Acupuncture is emerging as an alternative therapy for rheumatoid arthritis (RA. However, the molecular mechanism underlying this beneficial effect of acupuncture has not been fully understood. Here, we demonstrated that electroacupuncture at acupoints Zusanli (ST36, Xuanzhong (GB39; and Shenshu (BL23 markedly decreased the paw swelling and the histologic scores of inflammation in the synovial tissue, and reduced the body weight loss in an adjuvant-induced arthritis rat model. However, the electrical stimulation at nonacupoint did not produce any beneficial effects against the experimental arthritis. Most interestingly, the electroacupuncture treatment resulted in an enhanced immunostaining for vasoactive intestinal peptide (VIP, a potent anti-inflammatory neuropeptide, in the synovial tissue. Moreover, the VIP-immunostaining intensity was significantly negatively correlated with the scores of inflammation in the synovial tissue (r=−0.483, P=.0026. In conclusion, these findings suggest that electroacupuncture may offer therapeutic benefits for the treatment of RA, at least partially through the induction of VIP expression.

    Background: Peripheral arterial disease (PAD) is characterised by impaired leg blood flow, which contributes to claudication and reduced exercise capacity. This study investigated to what extent vasoactive enzymes might contribute to altered blood flow in PAD (Fontaine stage II). Methods: We...... compared femoral artery blood flow during reactive hyperaemia, leg-extension exercise and passive leg movement, and determined the level of vasoactive enzymes in skeletal muscle samples from the vastus lateralis in PAD (n = 10, 68.5 ± 6.5 years) and healthy controls (CON, n = 9, 62.1 ± 12.3 years). Leg...... than CON (1.04 ± 0.19 vs 0.50 ± 0.06 AU, P = 0.02), with no differences for other enzymes. Leg blood flow during exercise was correlated with prostacyclin synthase (P = 0.001). Conclusion: Elevated NADPH oxidase indicates that oxidative stress may be a primary cause of low nitric oxide availability...

    Full Text Available Preterm neonates often have hypotension which may be due to various etiologies. While it is controversial to define hypotension in preterm neonates, various vasoactive medications are commonly used to provide the cardiovascular support to improve the blood pressure, cardiac output, or to treat shock. However, the literature on the systemic and regional hemodynamic effects of these antihypotensive medications in neonates is deficient and incomplete, and cautious translation of findings from other clinical populations and animal studies is required. Based on a literature search on published reports, meta-analytic reviews, and selected abstracts, this review discusses the current available information on pharmacologic actions, clinical effects, and side effects of commonly used antihypotensive medications including dopamine, dobutamine, epinephrine, norepinephrine, vasopressin, and milrinone in preterm neonates.

    Vasoactive intestinal polypeptide (VIP) in the pig pancreas is localized to nerves, many of which travel along the pancreatic ducts. VIP stimulates pancreatic fluid and bicarbonate secretion like secretin. Electrical vagal stimulation in the pig causes an atropine-resistant profuse secretion...... of bicarbonate-rich pancreatic juice. In an isolated perfused preparation of the pig pancreas with intact vagal nerve supply, electrical vagal stimulation caused an atropine-resistant release of VIP, which accurately parallelled the exocrine secretion of juice and bicarbonate. Perfusion of the pancreas...... with a potent VIP-antiserum inhibited the effect of vagal stimulation on the exocrine secretion. It is concluded, that VIP is responsible for (at least part of) the neurally controlled fluid and bicarbonate secretion from the pig pancreas....

    The concentration of vasoactive intestinal polypeptide (VIP) was determined in peripheral venous plasma from 136 patients with liver cirrhosis without gastrointestinal bleeding or coma and from 112 controls. In eight patients (cirrhosis, six; fibrosis, one; steatosis, one) arteriovenous extraction...... is significantly elevated in peripheral plasma from patients with cirrhosis, probably due to porto-systemic shunting and/or compromised hepatic elimination. Hepatic elimination is still likely to account for the inactivation of most of the VIP escaping from the neurosynapses throughout the body in patients...

    Playing video games causes physical and psychological stress, including increased heart rate and blood pressure and aggression-related feelings. Use of mobile phones is very popular in Japan, and frequent ringing is a common and intrusive part of Japanese life. Atopic eczema/dermatitis syndrome is often exacerbated by stress. Stress increases serum IgE levels, skews cytokine pattern towards Th2 type, enhances allergen-induced skin wheal responses, and triggers mast cell degranulation via substance P, vasoactive intestinal peptide and nerve growth factor. (1). In the video game study, normal subjects (n = 25), patients with allergic rhinitis (n = 25) or atopic eczema/dermatitis syndrome (n = 25) played a video game (STREET FIGHTER II) for 2 h. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor, and in vitro production of total IgE, antihouse dust mite IgE and cytokines were measured. (2). In the mobile phone study, normal subjects (n = 27), patients with allergic rhinitis (n = 27) or atopic eczema/dermatitis syndrome (n = 27) were exposed to 30 incidences of ringing mobile phones during 30 min. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor were measured. Playing video games had no effect on the normal subjects or the patients with allergic rhinitis. In contrast, playing video games significantly enhanced allergen-induced skin wheal responses and increased plasma levels of substance P, vasoactive intestinal peptide and nerve growth factors in the patients with atopic eczema/dermatitis syndrome. Moreover, playing video games enhanced in vitro production of total IgE and anti-house dust mite IgE with concomitant increased production of IL-4, IL-10 and IL-13 and decreased production of IFN-gamma and IL-12 in the patients with atopic eczema/dermatitis syndrome. However, exposure

    Manual changeover of vasoactive drug infusion pumps (CVIP) frequently lead to haemodynamic instability. Some of the newest smart pumps allow automated CVIP. The aim of this study was to compare automated CVIP with manual 'Quick Change' relays. We performed a prospective, quasi-experimental study, in a university-affiliated intensive care unit (ICU). All adult patients receiving continuous i.v. infusion of vasoactive drugs were included. CVIP were successively performed manually (Phase 1) and automatically (Phase 2) during two 6-month periods. The primary endpoint was the frequency of haemodynamic incidents related to the relays, which were defined as variations of mean arterial pressure >15 mm Hg or heart rate >15 bpm. The secondary endpoints were the nursing time dedicated to relays and the number of interruptions in care because of CVIP. A multivariate mixed effects logistic regression was fitted for analytic analysis. We studied 1329 relays (Phase 1: 681, Phase 2: 648) from 133 patients (Phase 1: 63, Phase 2: 70). Incidents related to CVIP decreased from 137 (20%) in Phase 1 to 73 (11%) in Phase 2 (Ppumps in limiting the frequency of haemodynamic incidents related to relays and in reducing the nursing workload.

    We studied 20 patients with erectile dysfunction of vascular origin and 10 patients with psychological erectile dysfunction with Doppler ultrasound before and after injection of intra cavernous vasoactive substances. We observed that psychological erectile dysfunction, is characterized by normal vascular velocities in cavernous arteries (control group). In patients with vascular aetiology we obtained abnormal registrations that differentiated arterial from venous pathology. There was a significant difference in the diameter of the cavernous artery and the systolic flow after the injection of vasoactive substances

    Plasma vasoactive intestinal peptide (VIP) concentrations of normal individuals and patients with pancreatitis were studied using a VIP RIA kit. The inter-assay and intra-assay variation of this kit were between 2.1 and 9.4 %. The VIP levels increased in the acute phase of acute pancreatitis and patients with chronic pancreatitis. The VIP concentration increased during the first 30 min of glucose tolerance test, but this increase was much smaller than that in insulin. These results suggest that this kit is useful for physiologic and pathologic changes in the VIP level. (author)

  16. Negative attributions towards people with substance use disorders in South Africa: Variation across substances and by gender

    Directory of Open Access Journals (Sweden)

    Sorsdahl Katherine

    2012-08-01

    Full Text Available Abstract Background Little research has examined attitudes towards people who use substances in low and middle income countries (LMIC. Therefore, the present study examined the attributions made by the general South African population about people who use substances and whether these attributions differ by the type of substance being used, the gender of the person using the substance, or the characteristics of the person making the attribution. Method A convenience sample of 868 members of the general public was obtained through street-intercept methods. One of 8 vignettes portraying alcohol, cannabis, methamphetamine or heroin, with either a male or female as the protagonist was presented to each respondent. Respondents’ attitudes towards the specific cases were investigated. Results Respondents held equally negative views of the presented substances, with the exception of the cannabis vignette which was considered significantly less “dangerous” than the alcohol vignette. Respondents were more likely to offer “help” to women who use alcohol, but more likely to suggest “coercion into treatment” for men. Individuals who scored higher on the ASSIST were more likely to hold negative attitudes towards substance users and black African respondents were more likely to offer help to individuals who use substances. Conclusion The stigma associated with substance use in South Africa is high and not necessarily dependent on the drug of choice. However, a range of factors, including gender of the substance user, and ethnicity of the rater, may impact on stigma. Interventions designed to strengthen mental health literacy and gender-focused anti-stigma campaigns may have the potential to increase treatment seeking behaviour.

    A new radioimmunoassay which allows the measurement of the rat vasoactive intestinal polypeptide, was performed. VIP is present in the whole digestive tract of rat, mainly between the duodenum and the colon. 1.5% of the total VIP is present in brain. The VIP-like immunoreactivity appears to correspond to biologically active molecule since a radioreceptorassay using liver plasma membranes as the target tissue, gives the same results as the radioimmunoassay [fr

    The aim of present investigation is research of influence of vasoactive and neurometabolic medicines in stroke patients's rehabilitation. We had analysed 280 stroke patients. The degree of rehabilitation had been defined with the help of Barthel and Lindmark scales. The degree of cognitive functions's rehabilitation had been defined with the help of MMSE scale. For every medicine coefficients of efficiency were calculated. As the result of the present investigation the medicine's efficiency was found out. The most efficient medicines in ischaemic stroke patients's rehabilitation among the investigated ones are the medicines which activate the neuronal metabolism, first of all,--ceraxon (citicoline).

  1. Vasoactive intestinal peptide and electrical activity influence neuronal survival

    1986-01-01

    Blockage of electrical activity in dissociated spinal cord cultures results in a significant loss of neurons during a critical period in development. Decreases in neuronal cell numbers and 125 I-labeled tetanus toxin fixation produced by electrical blockage with tetrodotoxin (TTX) were prevented by addition of vasoactive intestinal peptide (VIP) to the nutrient medium. The most effective concentration of VIP was 0.1 nM. At higher concentrations, the survival-enhancing effect of VIP on TTX-treated cultures was attenuated. Addition of the peptide alone had no significant effect on neuronal cell counts or tetanus toxin fixation. With the same experimental conditions, two closely related peptides, PHI-27 (peptide, histidyl-isoleucine amide) and secretin, were found not to increase the number of neurons in TTX-treated cultures. Interference with VIP action by VIP antiserum resulted in neuronal losses that were not significantly different from those observed after TTX treatment. These data indicate that under conditions of electrical blockade a neurotrophic action of VIP on neuronal survival can be demonstrated

    The origin of migraine pain is still elusive, but increasingly researchers focus on the neuropeptides in the perivascular space of cranial vessels as important mediators of nociceptive input during migraine attacks. The parasympathetic neurotransmitters, pituitary adenylate cyclase activating...... peptide-38 (PACAP38) and vasoactive intestinal peptide (VIP) may be released from parasympathetic fibres and activate sensory nerve fibres during migraine attacks. Triptans are effective and well tolerated in acute migraine management but the exact mechanism of action is still debated. Triptans might...

    Assess changes in the number of prescriptions for peripheral and cerebral vasoactive drugs for the treatment of lower limb arteritis and cerebrovascular disease since the promulgation in 1995 of prescription standards for the treatment of lower limb arteritis. Assess compliance to prescription standards with a detailed analysis of patient features, prescriptions written for lower limb arteritis, cerebrovascular disease and concomitant diseases and evaluate changes in treatment costs for lower limb arteritis and cerebrovascular disease as well as cost of the full prescription, including treatments for associated diseases. This study was based on data recorded during the Permanent Study of Medical Prescriptions conducted from March 1994 to February 1995 and from March 1995 to February 1996 by the IMS. Prescription costs were established from the National Description Files of the IMS. Treatment costs were expressed as public price (FF) tax included. Prescriptions meeting the following criteria were selected for each period: prescriptions written by general practitioners for drugs with peripheral and cerebral vasoactivity (excepting calcium antagonists with a cerebral target) belonging to the Anatomic Therapeutic Classes C4A1 of the European Pharmaceutical Marketing Research Association, Bromly 1996; prescriptions for diagnoses 447.6 (arteritis) and 437.9 (cerebrovascular disease) according to the 9th WHO classification. A random sample of 500 prescriptions was selected to calculate costs. Since the advent of the prescription standards in 1995, prescriptions have dropped off by 6.3% for lower limb arteritis and by 14.8% for cerebrovascular disease. There was a 3.7 point decline in the percentage of multiple prescriptions of vasoactive drugs for lower limb arteritis (21.7% prior to March 1995 versus 18% after promulgation of the prescription standards, p > 0.1) and a 1.8 increase in the percentage of multiple prescriptions for cerebrovascular disease (14% prior to March

  4. Is chronic fatigue syndrome an autoimmune disorder of endogenous neuropeptides, exogenous infection and molecular mimicry?

    Staines, Donald R

    2004-01-01

    Chronic fatigue syndrome is a disorder characterised by prolonged fatigue and debility and is mostly associated with post-infection sequelae although ongoing infection is unproven. Immunological aberration is likely and this may prove to be associated with an expanding group of vasoactive neuropeptides in the context of molecular mimicry and inappropriate immunological memory. Vasoactive neuropeptides including vasoactive intestinal peptide (VIP) and pituitary adenylate activating polypeptide (PACAP) belong to the secretin/glucagon superfamily and act as hormones, neurotransmitters, immune modulators and neurotrophes. They are readily catalysed to smaller peptide fragments by antibody hydrolysis. They and their binding sites are immunogenic and are known to be associated with a range of autoimmune conditions. Vasoactive neuropeptides are widely distributed in the body particularly in the central, autonomic and peripheral nervous systems and have been identified in the gut, adrenal gland, reproductive organs, vasculature, blood cells and other tissues. They have a vital role in maintaining vascular flow in organs, and in thermoregulation, memory and concentration. They are co-transmitters for acetylcholine, nitric oxide, endogenous opioids and insulin, are potent immune regulators with primarily anti-inflammatory activity, and have a significant role in protection of the nervous system to toxic assault, promotion of neural development and the maintenance of homeostasis. This paper describes a biologically plausible mechanism for the development of CFS based on loss of immunological tolerance to the vasoactive neuropeptides following infection, significant physical exercise or de novo. It is proposed that release of these substances is accompanied by a loss of tolerance either to them or their receptor binding sites in CFS. Such an occurrence would have predictably serious consequences resulting from compromised function of the key roles these substances perform. All

    This study was conducted to obtain morphological proof of innervating nerve fibres in the glands of the human eyelid (accessory lacrimal glands of Wolfring, meibomian glands, goblet cells, glands of Zeis, glands of Moll, sweat glands, glands of lanugo hair follicles) and identification of the secretomotorically active neuropeptide vasoactive intestinal polypeptide (VIP) as a common transmitter. Epoxy-embedded ultrathin sections of tissue samples from human eyelids were studied using electron microscopy. Paraffin sections fixed in Bouin-Hollande solution were immunostained with rabbit antiserum against VIP. With the electron microscope we were able to identify nerves in the glandular stroma of all the glands examined with the exception of goblet cells. Intraepithelial single axons were only seen in the parenchyma of Wolfring glands. The morphological findings corresponded with the immunological finding of VIP-positive, nerve-like structures in the same locations, with the exception of lanugo hair follicle glands, and goblet cells. Our findings indicate that the glands of the eyelids and main lacrimal gland represent a functional unit with VIP as a possible common stimulating factor. Copyright 1999 Academic Press.

    D. R. Staines

    2008-01-01

    Full Text Available Vasoactive neuropeptides (VNs such as pituitary adenylate cyclase-activating polypeptide (PACAP and vasoactive intestinal peptide (VIP have critical roles as neurotransmitters, vasodilators including perfusion and hypoxia regulators, as well as immune and nociception modulators. They have key roles in blood vessels in the central nervous system (CNS including maintaining functional integrity of the blood brain barrier (BBB and blood spinal barrier (BSB. VNs are potent activators of adenylate cyclase and thus also have a key role in cyclic AMP production affecting regulatory T cell and other immune functions. Virchow-Robin spaces (VRSs are perivascular compartments surrounding small vessels within the CNS and contain VNs. Autoimmunity of VNs or VN receptors may affect BBB and VRS function and, therefore, may contribute to the aetiology of neurological-related conditions including multiple sclerosis, Parkinson's disease, and amyotrophic lateral sclerosis. VN autoimmunity will likely affect CNS and immunological homeostasis. Various pharmacological and immunological treatments including phosphodiesterase inhibitors and plasmapheresis may be indicated.

    2016-01-01

    This study characterized mental health facilities that offer suicide prevention services or outcome follow-up after discharge. The study analyzed data from 8,459 U.S. mental health facilities that participated in the 2010 National Mental Health Services Survey. Logistic regression analyses were used to compare facilities that offered neither of the prevention services with those that offered both or either service. About one-fifth of mental health facilities reported offering neither suicide prevention services nor outcome follow-up. Approximately one-third offered both, 25% offered suicide prevention services only, and 21% offered only outcome follow-up after discharge. Facilities that offered neither service were less likely than facilities that offered either to offer comprehensive support services or special programs for veterans; to offer substance abuse services; and to be accredited, licensed, or certified. Further examination of facilitators and barriers in implementing suicide prevention services in mental health facilities is warranted.

    Solid crystalline phases containing two cocrystallized components offer a new development pathway whereby one can potentially improve the physical characteristics (i.e., equilibrium solubility, dissolution rate, solid-state stability, etc.) of a drug substance that exhibits a profile that is less than desirable. In this commentary, the topic of pharmaceutical cocrystals will be briefly explored, and a short exposition of the solubility and dissolution rate advantages that have been realized in various systems will be provided. The Guidance for Industry document recently proposed by United States Food and Drug Administration will be outlined, and its requirements explained. Finally, the subset of pharmaceutical cocrystals that consist of a drug substance and a salt of that substance (termed a salt cocrystal) will be examined to illustrate this additional class of pharmaceutical cocrystals that may offer significant scientific and regulatory advantages.

    2009-09-01

    This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to standardized criteria to determine whether they offered to sell psilocybin or psilocybin spores. No attempts were made to procure the products offered for sale in order to ascertain whether the marketed psilocybin was in fact "genuine" or "counterfeit." Of the 800 links examined, 58% led to websites offering to sell psilocybin spores. Additionally, evidence that whole Psilocybe mushrooms are offered for sale online was obtained. Psilocybin and psilocybin spores were found to be widely available for sale over the Internet. Online purchase of psilocybin may facilitate illicit use of this potent psychoactive substance. Additional studies are needed to assess whether websites offering to sell psilocybin and psilocybin spores actually deliver their products as advertised.

  13. Vasoactive receptors in abdominal blood vessels of the dogfish shark, Squalus acanthias.

    Science.gov (United States)

    Evans, D H

    2001-01-01

    Previous studies have demonstrated that the ventral aorta of the dogfish shark, Squalus acanthias, responds to a variety of cell-signaling agents. To investigate the generality of vasoactive receptors in the shark vasculature, in particular a conductance artery (anterior mesenteric) and vein (posterior intestinal), I measured the effect of acetylcholine, endothelin, nitric oxide, natriuretic peptides, and prostaglandins on tension in isolated rings from these vessels. Both vessels responded to these agents, and responses to receptor-specific ligands for endothelin and natriuretic peptide receptors suggest that B-type endothelin receptors are expressed in both vessels and that the artery expresses both A- and B-type natriuretic peptide receptors; however, the vein (like the ventral aorta) expresses only the B-type natriuretic peptide receptor. My data suggest that a suite of signaling systems is ubiquitous in both arteries and veins in at least this elasmobranch species. Their role in hemodynamics and osmoregulation (perfusion of gill and rectal gland) remains to be determined.

    Li Jiaqiang; Li Wei

    1999-01-01

    Objective: To explore the plasma concentration of the endothelium-derived vasoactive factors such as endothelin (ET), thromboxane B 2 (TXB 2 ), 6-keto-prostaglandin F 1α (6-K-PGF 1α ) and their effects on regional cerebral blood flow (rCBF). Methods: Plasma ET, TXB 2 , 6-K-PGF 1α were measured with radioimmunoassay in 64 patients with acute stroke and 30 control subjects. Meanwhile, the rCBF was determined using 133 Xe inhalation method in all patients and the control group. The data of stroke group were studied by t test. The linear correlation between alterations of vasoactive factors and rCBF was analysed. Results: The mean ET, TXB 2 plasma level [respectively (103.8 +- 42.6) and (152.2 +- 59.1) ng/L] was significantly higher in 64 stroke patients than in normal subjects [respectively (47.8 +- 7.8) and (84.4 +- 11.5) ng/L], P 1α [(93.7 +- 28.8) ng/L] as compared with the healthy controls [(104.7 +- 17.4) ng/L, P -1 ·min -1 ; mean: (46.9 +- 7.9) mL·100 g -1 ·min -1 vs (63.3 +- 6.5) mL·100 g -1 ·min -1 , P 2 in patients with large infarct or hemorrhage volume were markedly higher than those of patients with small foci; to the opposite, rCBF was decreased remarkably. The same situation was seen while compared the date of patients with basilar nuclei stroke with those of patients with lobar stroke. Both ET and TXB 2 had a significant negative correlation with rCBF ( r = -0.751, -0.454, P 2 and rCBF might be useful in assessment of brain damage caused by acute stroke

    Although there is considerable literature pertaining to IgE and non IgE-mediated food allergy, there is a paucity of information on non-immune mediated reactions to foods, other than metabolic disorders such as lactose intolerance. Food additives and naturally occurring 'food chemicals' have long been reported as having the potential to provoke symptoms in those who are more sensitive to their effects. Diets low in 'food chemicals' gained prominence in the 1970s and 1980s, and their popularity remains, although the evidence of their efficacy is very limited. This review focuses on the available evidence for the role and likely adverse effects of both added and natural 'food chemicals' including benzoate, sulphite, monosodium glutamate, vaso-active or biogenic amines and salicylate. Studies assessing the efficacy of the restriction of these substances in the diet have mainly been undertaken in adults, but the paper will also touch on the use of such diets in children. The difficulty of reviewing the available evidence is that few of the studies have been controlled and, for many, considerable time has elapsed since their publication. Meanwhile dietary patterns and habits have changed hugely in the interim, so the conclusions may not be relevant for our current dietary norms. The conclusion of the review is that there may be some benefit in the removal of an additive or a group of foods high in natural food chemicals from the diet for a limited period for certain individuals, providing the diagnostic pathway is followed and the foods are reintroduced back into the diet to assess for the efficacy of removal. However diets involving the removal of multiple additives and food chemicals have the very great potential to lead to nutritional deficiency especially in the paediatric population. Any dietary intervention, whether for the purposes of diagnosis or management of food allergy or food intolerance, should be adapted to the individual's dietary habits and a suitably

    Intestinal gluconeogenesis (IGN) promotes metabolic benefits through activation of a gut-brain neural axis. However, the local mediator activating gluconeogenic genes in the enterocytes remains unknown. We show that (i) vasoactive intestinal peptide (VIP) signaling through VPAC1 receptor activates the intestinal glucose-6-phosphatase gene in vivo, (ii) the activation of IGN by propionate is counteracted by VPAC1 antagonism, and (iii) VIP-positive intrinsic neurons in the submucosal plexus are increased under the action of propionate. These data support the role of VIP as a local neuromodulator released by intrinsic enteric neurons and responsible for the induction of IGN through a VPAC1 receptor-dependent mechanism in enterocytes. © 2015 John Wiley & Sons Ltd.

These conditions have been attributed variably to neuroinflammatory and neurodegenerative processes. While autoimmune pathology, at least in part, has long been suspected in these conditions proof has been elusive. Autoimmune pathomechanisms affecting the blood–brain barrier (BBB or blood–spinal barrier (BSB may predispose the BBB/BSB to ‘leakiness’ and be a precursor to additional autoimmune events resulting in neuroinflammatory or neurodegenerative processes. The aim of the paper is to postulate immunopathology of the cerebrospinal perivascular compartment involving certain vasoactive neuropeptides, specifically pituitary adenylate cyclase-activating polypeptide (PACAP and vasoactive intestinal peptide (VIP, in the etiology of certain neuropsychiatric fatigue-related conditions such as MS, ALS, PD, and CFS. Vasoactive neuropeptides (VNs such as PACAP and VIP have critical roles as neurotransmitters, vasodilators including perfusion and hypoxia regulators, and immune and nociception modulators. PACAP and VIP are widely distributed in the central nervous system (CNS and have key roles in CNS blood vessels including maintaining functional integrity of the BBB and BSB. Autoimmunity affecting these VNs would likely have a detrimental effect on BBB and BSB functioning arguably predisposing to further pathological processes. Virchow–Robin spaces (VRS are perivascular compartments surrounding small vessels within the CNS which

    The Vasoactive Intestinal Peptide (VIP) is a 28-amino acid polypeptide with a great numbers of receptors in tumoral cells, including adenocarcinomas and pancreatic and colon carcinomas. The VIP molecule contains two tyrosine residues, in positions 10 and 22, that are theoretically equally susceptible to iodination, The VIP was labeled with 131-iodine by direct method using Iodogen as oxidant agent: 15.03 mmol VIP + 0.10 nmol KI + [ 131 I]NaI + 13.9 mmol Iodogen; the final volume was adjust to 100 μL using 0.2 M phosphate buffer, pH 7.5 and the reaction proceed with stirring for 30 minutes at room temperature. The radiochemical purity was determined by electrophoresis (Whatman 1MM paper; 0.05 M barbital buffer; pH 8.6; 150 V; 40 minutes) that indicates low percent of free 131-iodine. The high performance liquid chromatography (HPLC) system using RPC 18 , 10 μm, 4 x 250mm column, was able to separate the different radiochemical species, only when an isocratic mixture of acetonitrile: 0.1% trifluoroacetic acid (27:73) was used, with 0.5 mL/min. flux.

  4. Effects of vasoactive intestinal peptide on vascular conductance are unaffected by anesthesia

    1988-01-01

    In rats anesthetized with ketamine and pentobarbital (KET/PB), vasoactive intestinal peptide (VIP) increases vascular conductance (VC) in the salivary gland, pancreas, and thyroid gland, whereas no changes in VC are observed in a number of other organs. Because anesthesia may alter the responsiveness of physiological systems, we compared the effects of VIP on organ VC in conscious or anesthetized rats. Chronically catheterized rats were studied in the conscious state or 30 min after induction of anesthesia with KET/PB, isoflurane, or Inactin. Blood flows were measured by the reference sample version of the radioactive microsphere (MS) technique using two MS injections ( 141 Ce-MS/ 85 Sr-MS). Mean arterial blood pressure was monitored and used in the calculation of VC. Organ VCs were similar under basal conditions in conscious and anesthetized rats. VIP infusion caused systemic hypotension and increased VCs in the salivary gland, pancreas, and thyroid gland, and these responses were largely unaffected by anesthesia. These results indicate that the anesthetics used do not alter basal VC or the responsiveness of the vasculature to exogenous VIP

    All sectors of society should be involved in reducing substance misuse, including businesses. However, the business sector is typically involved only to the extent that their products compel them to be (e.g., alcohol producers promoting responsible alcohol consumption). This article examines why business participation has been limited and how embedding prevention within a framework of health promotion could increase participation. It reviews both Hungarian and international cases, concluding that although corporate social responsibility (CSR) offers a framework to approach substance misuse reduction, a different perception of the role of the business sector is necessary to make it viable.

  8. Is urbanization a risk factor for substance misuse?

    2008-07-01

    More than half of the world's population is living in urban areas, but the evidence about urban-rural differences in drug use is not clearly defined. The present paper aims to review the international literature addressing the role of urbanization and related parameters in association with substance misuse. In particular, the evidence of urbanization being a risk factor for substance misuse is examined. Although it has been suggested that substance misuse is typically a characteristic of large urban areas, this did not appear to be a consistent observation from the literature review. Furthermore, the urban context may offer a relative proximity of health services and prompter emergency intervention in case of overdose. Although more efforts have to be put into explaining substance misuse in general, identifying which characteristics of the urban context are modifiable, and under what circumstances, is an important theoretical, empirical, and public health question.

    Lungs have many non-respiratory metabolic functions, of which some take place in the capillary endothelium, while others are in parenchymal lung tissue. We have studied the role of the lungs in the metabolism of vasoactive and some other hormones by comparing patients who have undergone lung resection to those having various obstructive or fibrotic lung diseases. We have also compared these groups with persons in good physical health. The data suggested that lung resection patients had low angiotensin II levels in plasma but the response of angiotensin II to exercise was normal. Also adrenalin concentration was low in the lung resection group while dopamine did not show any significant difference between the groups. When hormone levels were correlated to the exercise data, renin levels were especially related to physical condition. Serum post-exercise renin values were inversely related to the uneven distribution of lung perfusion, possibly thus reflecting the diminished pulmonary vascularization. A negative association was found between angiotensin II and diffusion capacity. Thus, the angiotensin II levels may preferably be controlled by the non-circulatory functions of the lungs.

    Proline-rich oligopeptides (PROs) are a large family which comprises the bradykinin-potentiating peptides (BPPs). They inhibit the activity of the angiotensin I-converting enzyme (ACE) and have a typical pyroglutamyl (Pyr)/proline-rich structure at the N- and C-terminus, respectively. Furthermore......, PROs decrease blood pressure in animals. In the present study, the isolation and biological characterization of a novel vasoactive BPP isolated from the skin secretion of the frog Brachycephalus ephippium is described. This new PRO, termed BPP-Brachy, has the primary structure WPPPKVSP and the amidated...... form termed BPP-BrachyNH2 inhibits efficiently ACE in rat serum. In silico molecular modeling and docking studies suggest that BPP-BrachyNH2 is capable of forming a hydrogen bond network as well as multiple van der Waals interactions with the rat ACE, which blocks the access of the substrate to the C...

    2008-07-01

    Full Text Available Abstract Background The neuropeptide vasoactive intestinal peptide (VIP is widely distributed in the adult central nervous system where this peptide functions to regulate synaptic transmission and neural excitability. The expression of VIP and its receptors in brain regions implicated in learning and memory functions, including the hippocampus, cortex, and amygdala, raise the possibility that this peptide may function to modulate learned behaviors. Among other actions, the loss of VIP has a profound effect on circadian timing and may specifically influence the temporal regulation of learning and memory functions. Results In the present study, we utilized transgenic VIP-deficient mice and the contextual fear conditioning paradigm to explore the impact of the loss of this peptide on a learned behavior. We found that VIP-deficient mice exhibited normal shock-evoked freezing behavior and increases in corticosterone. Similarly, these mutant mice exhibited no deficits in the acquisition or recall of the fear-conditioned behavior when tested 24-hours after training. The VIP-deficient mice exhibited a significant reduction in recall when tested 48-hours or longer after training. Surprisingly, we found that the VIP-deficient mice continued to express circadian rhythms in the recall of the training even in those individual mice whose wheel running wheel activity was arrhythmic. One mechanistic explanation is suggested by the finding that daily rhythms in the expression of the clock gene Period2 continue in the hippocampus of VIP-deficient mice. Conclusion Together these data suggest that the neuropeptide VIP regulates the recall of at least one learned behavior but does not impact the circadian regulation of this behavior.

  19. Neural Circuitry of Impaired Emotion Regulation in Substance Use Disorders.

    Science.gov (United States)

    Wilcox, Claire E; Pommy, Jessica M; Adinoff, Bryon

    2016-04-01

    Impaired emotion regulation contributes to the development and severity of substance use disorders (substance disorders). This review summarizes the literature on alterations in emotion regulation neural circuitry in substance disorders, particularly in relation to disorders of negative affect (without substance disorder), and it presents promising areas of future research. Emotion regulation paradigms during functional magnetic resonance imaging are conceptualized into four dimensions: affect intensity and reactivity, affective modulation, cognitive modulation, and behavioral control. The neural circuitry associated with impaired emotion regulation is compared in individuals with and without substance disorders, with a focus on amygdala, insula, and prefrontal cortex activation and their functional and structural connectivity. Hypoactivation of the rostral anterior cingulate cortex/ventromedial prefrontal cortex (rACC/vmPFC) is the most consistent finding across studies, dimensions, and clinical populations (individuals with and without substance disorders). The same pattern is evident for regions in the cognitive control network (anterior cingulate and dorsal and ventrolateral prefrontal cortices) during cognitive modulation and behavioral control. These congruent findings are possibly related to attenuated functional and/or structural connectivity between the amygdala and insula and between the rACC/vmPFC and cognitive control network. Although increased amygdala and insula activation is associated with impaired emotion regulation in individuals without substance disorders, it is not consistently observed in substance disorders. Emotion regulation disturbances in substance disorders may therefore stem from impairments in prefrontal functioning, rather than excessive reactivity to emotional stimuli. Treatments for emotion regulation in individuals without substance disorders that normalize prefrontal functioning may offer greater efficacy for substance disorders

  1. Peptidergic modulation of efferent sympathetic neurons in intrathoracic ganglia regulating the canine heart.

    Science.gov (United States)

    Armour, J A

    1989-05-01

    When either substance P or vasoactive intestinal peptide was injected into an acutely decentralized intrathoracic sympathetic ganglion, short-lasting augmentation of cardiac chronotropism and inotropism was induced. These augmentations were induced before the fall in systemic arterial pressure occurred which was a consequence of these peptides leaking into the systemic circulation in enough quantity to alter peripheral vascular resistance directly. When similar volumes of normal saline were injected into an intrathoracic ganglion, no significant cardiac changes were induced. When substance P or vasoactive intestinal peptide was administered into an intrathoracic ganglion, similar cardiac augmentations were induced either before or after the intravenous administration of hexamethonium. In contrast, when these peptides were injected into an intrathoracic ganglion in which the beta-adrenergic blocking agent timolol (0.1 mg/0.1 ml of normal saline) had been administered no cardiac augmentation occurred. These data imply that in the presence of beta-adrenergic blockade intraganglionic administration of substance P or vasoactive intestinal peptide does not modify enough intrathoracic neurons to alter cardiac chronotropism and inotropism detectably. When neuropeptide Y was injected into an intrathoracic ganglion, no cardiac changes occurred. However, when cardiac augmentations were induced by sympathetic preganglionic axon stimulation these were enhanced following the intraganglionic administration of neuropeptide Y. As this effect occurred after timolol was administered into the ipsilateral ganglia, but not after intravenous administration of hexamethonium, it is proposed that the effects of neuropeptide Y are dependent upon functioning intrathoracic ganglionic nicotinic cholinergic synaptic mechanisms. Intravenous administration of either morphine or [D-ala2,D-leu5]enkephalin acetate did not alter the capacity of the preganglionic sympathetic axons to augment the heart

    Vascular sensitization to vasoactive amines (VAA) may be critical for the development of experimental autoimmune encephalitis as well as other autoimmune diseases. Some inbred stains of mice such as SJL/J are particularly sensitive to the effects of VAA while others (BALB/c) are not. This study was performed to determine if the differing response to VAA in vivo is due to differing levels of binding of VAA to cultured brain endothelial (En) cells in vitro. Cells were isolated, grown to confluence, washed twice with binding buffer and incubated with either 3 H-histamine, 3 H-mepyramine or 3 H-5 hydroxytryptamine (5HT) for 1 hour at 37 0 C. Results showed that the BALB derived En cells specifically bound approximately twice as much mepyramine and three times as much 5-HT as the SJL derived En cells. The relative low binding of VAA to SJL En cells may reflect the extreme in vivo sensitivity that this mouse strain displays toward VAA. These seemingly paradoxical levels of VAA binding in the cultured cerebral endothelium may be due to genetic factors and may give insight into diseases that affect the blood brain barrier

    1977-06-01

    A sensitive and specific radioimmunoassay for vasoactive intestinal polypeptide (VIP) has been developed, which can detect 3.3 pmol x L/sup -1/ of the peptide in plasma. Antisera to highly purified porcine VIP coupled to albumin were raised in eight rabbits. The final dilution, the avidity, and the specificity of each antiserum were determined. /sup 125/I-VIP served as label, and highly purified porcine VIP was used as standard. Separation of antibody-bound and free VIP was achieved by plasma-coated charcoal. Nonspecific interference with the assay system was excluded by extraction of plasm samples with ethanol. The reliability of the assay was investigated by recovery experiments, by serial dilution of plasma samples with high concentration of endogenous VIP, and by immunosorption. The within-and between assay reproducibility at a concentration of 18.3 pmol x L/sup -1/ was 1.6 and 2.3 pmol x L/sup -1/ (1 S.D.), respectively. Median fasting concentration of VIP in plasma from 74 normal subjects was 7.3 pmol x L/sup -1/ (range: 0 to 20.0 pmol x L/sup -1/).

  4. Substance abuse and cancer.

    2017-01-01

    Substance abuse is a health problem with serious psychological and psychiatric dimensions and multiple social and economic consequences. Cancer is a disease that threatens not only life and physical integrity but mental health as well. Oncology patients suffer from mental disorders in high rates, especially from depression and anxiety. The role of substance abuse in the pathogenesis of cancer is studied systematically, since there are research data supporting the mutagenic effects of certain substances. It has been supported that a possible dysregulation of the immune system is linked to the oncogenic processes induced by substances of abuse. Specifically, opioids are the first addictive substances that have been identified as oncogenic factors. However, conflicting results have been offered by experimental animal studies, which showed that opioids, such as morphine, depending on the dosage administered, may not only enhance the process of tumor growth, but also inhibit it. Additionally, research data indicate that the use of cannabis may be associated with cancer, either as an independent factor or in relation to other mutagenics, although it is not yet clear to which extent these effects may be connected to the disease, especially once the consumption of tobacco and alcohol by these patients are taken into account. However, it has been argued that certain cannabinoids may have biological -anticancer- activities which could be used therapeutically without being accompanied by the corresponding 9-tetrahydrocannabinol psychoactive effects. It is well known that alcohol is a risk factor for developing head and neck cancer, and epidemiological studies indicate that the higher the consumption of alcohol, the more mortality due to cancer increases. In addition, it is suggested that there is no safety level for alcohol consumption regarding the risk of developing cancer; that is even a minimum daily consumption is associated with the occurrence of certain types of cancer

    Adolescents who refuse direct cannabis offers and remain non-users represent a potentially very informative, yet surprisingly understudied group. We examined a range of risk and protective factors putatively associated with this poorly understood "cannabis-resilient" profile. Paper-and-pencil questionnaires assessing substance use, peer and family relations, and behavioral and personality characteristics were completed by 19,303 middle- and high-school students from 82 schools in Norway (response rate 84%) The lifetime prevalence of cannabis use was 7.6%. Another 10.4% reported no use of the drug despite having received recent cannabis offers. Results from the multinomial logistic regression revealed a set of characteristics differentiating adolescents who resisted such offers from those who: (a) neither received the offers nor used, and, more importantly, (b) used the drug. Specifically, parent-child relationship quality, negative drug-related beliefs, absence of close relationships with cannabis-users, low delinquency, no regular tobacco use, and infrequent alcohol intoxication were all associated with increased odds of being in the cannabis-resilient vs. cannabis-user group. This pattern of results was comparable across middle- and high-school cohorts, but the parent-child relationship quality and delinquency were significantly associated with cannabis-resilient vs. cannabis-use outcome only among younger and older adolescents, respectively. Among other low-risk characteristics, better relationships with parents and beliefs that drug use is problematic were associated with adolescents' refusals to accept cannabis offers. These results may have implications for novel preventive strategies targeting cannabis-exposed adolescents. Copyright © 2016. Published by Elsevier Ireland Ltd.

    In the present study, we aimed to examine the effects of soya oligosaccharides (SOS) and soya oligopeptides (SOP) on blood lipid levels, release of vasoactive substances, antioxidant activity and faecal bile acid (FBA) excretion in rats fed a high-fat diet (HFD). Male Sprague-Dawley rats were evenly divided into five groups according to diets as follows: regular diet (control), HFD, HFD enriched with 2 % of SOS (SOS), HFD enriched with 3 % of SOP (SOP) and HFD enriched with 2 % SOS and 3 % SOP (SOSP). The results showed that SOS and SOP significantly reduced plasma total cholesterol, LDL-cholesterol and TAG, whereas HDL-cholesterol concentration was significantly increased. Furthermore, SOS and SOP reduced plasma apoB, apoE and the apoB:apoAI ratio, whereas apoAI was significantly increased. Moreover, SOS and SOP also reduced plasma thromboxane A₂ (TXA₂) and the TXA₂:prostacyclin (PGI₂) ratio, whereas plasma PGI₂ and nitric oxide were significantly increased. In addition, SOS and SOP significantly reduced serum and liver malondialdehyde concentrations and increased FBA excretion. However, we did not observe obvious influences of SOS and SOP on superoxide dismutase activities in the liver of HFD-fed rats. The combination of 2 % SOS and 3 % SOP showed a more marked effect than SOS or SOP alone in improving the lipid profile, release of vasoactive substances and increasing FBA excretion (P < 0.05). In summary, SOS and SOP might help prevent atherosclerosis through improving abnormal blood lipid levels, regulating vasoactive substances and protecting against oxidative stress.

    Methods, principles, normal values, reproducibility and clinical indications of rCBF-measurements, using the intraartrial 133-Xenon-clearance-technique, are presented. The effect of vaso- and metabolically active drugs on cerebral blood flow was examined in 215 patients, suffering from cerebral ischemia. Significant increase of rCBF was ascertained after intravenous injection of centrophenoxine, pyrithioxine, extractum sanguis deproteinatus, piracetam and solutions of low molecular dextran. All the other drugs tested proved to be either without any effect or caused decrease of rCBF. In 130 patients with obstructive disease of internal carotid artery after surgery at an interval of 6 - 8 weeks and 1 year a significant increase of CBF could be stated. The rank of psychological tests and quantitative EEF-investigations relating to evidence of efficacy of metabolically active drugs is discussed critically. Therapeutic efficacy and clinical relevance of vaso- and metabolically active drugs in cerebral ischemia of man are to be substantiated only by double-blind controlled studies.

    Early enteral nutrition (EEN) in critically ill patients is associated with significant benefit as well as elevated risk of complications. Concomitant use of EEN with vasopressors has been associated with nonocclusive bowel necrosis in critically ill patients with hemodynamic instability. The decision when to initiate enteral nutrition in hemodynamically unstable patients that require vasoactive substances remains a clinical dilemma. This review summarizes the effect of EEN and vasoactive agents on gastrointestinal blood flow and perfusion in critically ill patients, based on current evidence. Animal and clinical data involving simultaneous administration of EEN and vasoactive agents for hemodynamic instability are reviewed, and the factors related to the safety and effectiveness of EEN support in this patient population are analyzed. Moreover, practical recommendations are provided. Additional randomized clinical trials are warranted to provide cutting-edge evidence-based guidance about this issue for practitioners of critical care.

  11. Should there be both categorical and dimensional criteria for the substance use disorders in DSM-V?

    Science.gov (United States)

    Helzer, John E; van den Brink, Wim; Guth, Sarah E

    2006-09-01

    As discussed in the following literature review, the relative advantages of categorical and dimensional criteria for classifying the substance use disorders (SUDs) have been debated for many years. The scheduled revision of the Diagnostic and Statistical Manual (DSM) offers an opportunity to re-examine this question. Both categorical and dimensional approaches to diagnosis offer advantages, both may in fact be necessary for a comprehensive taxonomy. One means of resolving debate about the direction to take in revising DSM-V and simultaneously of achieving maximum taxonomic utility is to include both categorical and dimensional criteria in DSM-V. This could be accomplished by first defining a set of categorical criteria, as in the previous editions of the DSM. Corresponding dimensional criteria could then be created using a more empirical methodology. In this paper we review some of the relevant literature, offer a specific proposal for a dimensional component for the DSM-V substance use disorders that also preserves the categorical definitions and suggest areas for additional research relevant the this agenda. There is evidence that alcohol and other forms of substance abuse and dependence are heterogeneous categories and that the SUDs can be conceptualized viably as arrayed along a continuum. Amplifying clinically derived categorical definitions with more empirically derived dimensional components to better capture this variability is a particularly important consideration for a substance use research agenda for DSM-V. It is crucial that a dimensional approach be offered in some form in DSM-V; but it is also vital that any dimensional approach be linked to the categorical definition. The proposal offered herein provides a model for amplifying categorical definitions with a dimensional component in a way that is evolutionary and not disruptive to the existing taxonomy.

    Objective: To seek for an effective way to acquire radiolabeled vasoactive intestinal peptide (VIP) with excellent in vivo stability. N-succinimidyl-3-iodo-125-benzoate (S 125 IB) came from radioiodination of N-succinimidyl-3-(tri-n-butylstannyl) benzoate (ATE) precursor and then conjugated with VIP to form 125 IBA-VIP. The labelling procedure was optimized; the in vitro stability and biological activity were evaluated. Methods: 1) Radiolabeling of ATE precursor was achieved with iodogen oxidant and the influential factors were considered in this procedure. The labeling efficiency was determined by thin layer chromatography (TLC) and the purification was carried out by Sep-pak silica gel cartridge. The stability was detected by TLC after 2 h storage in dark at 4 degree C. 2) Conjugation of S 125 IB and VIP. The labelling efficiency was determined with RP TLC and the purification was carried out with high performance liquid chromatography (HPLC, RP C18 column). Trichloroacetic acid (TCA) precipitation method was applied to evaluate the in vitro stability while the biological activity was determined by cell binding experiments with SGC7901 cell lines. Results: 1) S 125 IB experiments. The radioiodination of ATE was performed well for 5 min at 25 degree C with 10 micrograms of iodogen at suitable mole ratio (3-8:1) of ATE/Na 125 I, the labelling efficiency was about 96%. The stability was kept well at 4 degree C in dark, no significant decrease of S 125 IB was observed. 2) The conjugation efficiency of S 125 IB and VIP was above 75% with TLC. HPLC showed the different retention time (t R ) as follows, 125 IBA-VIP: 13.3 min, S 125 IB: 19.6 min, VIP: 8.32 min. The stability of 125 IBA-VIP was better than 125 I-VIP from direct radioiodination of VIP with iodogen oxidant, only 2.85% decrease was found after 7 d at 4 degree C. The biological activity of 125 IBA-VIP was kept as well as 125 I-VIP under the condition of 37 degree C 60 min. Conclusions: The indirect

    Full Text Available Antimicrobial peptides represent an emerging category of therapeutic agents with remarkable structural and functional diversity. Modified vasoactive intestinal peptide (VIP (VIP analogue 8 with amino acid sequence “FTANYTRLRRQLAVRRYLAAILGRR” without haemolytic activity and cytotoxicity displayed enhanced antimicrobial activities against Staphylococcus aureus (S. aureus ATCC 25923 and Escherichia coli (E. coli ATCC 25922 than parent VIP even in the presence of 180 mM NaCl or 50 mM MgCl2, or in the range of pH 4–10. VIP analogue 8 was expressed as fusion protein thioredoxin (Trx-VIP8 in E. coli BL21(DE at a yield of 45.67 mg/L. The minimum inhibitory concentration (MIC of the recombinant VIP analogue 8 against S. aureus ATCC 25923 and E. coli ATCC 25922 were 2 μM. These findings suggest that VIP analogue 8 is a promising candidate for application as a new and safe antimicrobial agent.

    Kuniomi Ishimori and Henri Piéron were the first researchers to introduce the concept and experimental evidence for a chemical factor that would presumably accumulate in the brain during waking and eventually induce sleep. This substance was named hypnotoxin. Currently, the variety of substances which have been shown to alter sleep includes peptides, cytokines, neurotransmitters and some substances of lipidic nature, many of which are well known for their involvement in other biological activities. In this chapter, we describe the sleep-inducing properties of the vasoactive intestinal peptide, prolactin, adenosine and anandamide.

    To investigate the possible role and clinical significance of vasoactive intestinal peptide (VIP) and somatostatin(SS) in the irritable bowel syndrome (IBS), the VIP and SS in the plasma and sigmoid mucosa were measured by radioimmunoassay in the control group and the IBS group. The VIP concentration in the plasma and sigmoid mucosa of the IBS patients with constipation was significantly higher than that of the control group (P<0.01), while that of the IBS patients with diarrhea was significantly lower than that of the control group (P<0.05). The SS concentration in two sites was significantly elevated in IBS patients of both types and was significantly higher in IBS with constipation than in IBS with diarrhea (P<0.05). Conclusion: The VIP and SS in IBS are abnormal, which might play a role in the pathogenesis of IBS. The plasma and mucosa concenration of VIP and SS in two kinds of IBS patients are significantly different, which indicates that there might be different pathophysiological basis involved in the pathogenesis of the two kinds of IBS patients.

  16. Amelioration of cardiac function and activation of anti-inflammatory vasoactive peptides expression in the rat myocardium by low level laser therapy.

    Directory of Open Access Journals (Sweden)

    Martha Trindade Manchini

    Full Text Available Low-level laser therapy (LLLT has been used as an anti-inflammatory treatment in several disease conditions, even when inflammation is a secondary consequence, such as in myocardial infarction (MI. However, the mechanism by which LLLT is able to protect the remaining myocardium remains unclear. The present study tested the hypothesis that LLLT reduces inflammation after acute MI in female rats and ameliorates cardiac function. The potential participation of the Renin-Angiotensin System (RAS and Kallikrein-Kinin System (KKS vasoactive peptides was also evaluated. LLLT treatment effectively reduced MI size, attenuated the systolic dysfunction after MI, and decreased the myocardial mRNA expression of interleukin-1 beta and interleukin-6 in comparison to the non-irradiated rat tissue. In addition, LLLT treatment increased protein and mRNA levels of the Mas receptor, the mRNA expression of kinin B2 receptors and the circulating levels of plasma kallikrein compared to non-treated post-MI rats. On the other hand, the kinin B1 receptor mRNA expression decreased after LLLT. No significant changes were found in the expression of vascular endothelial growth factor (VEGF in the myocardial remote area between laser-irradiated and non-irradiated post-MI rats. Capillaries density also remained similar between these two experimental groups. The mRNA expression of the inducible nitric oxide synthase (iNOS was increased three days after MI, however, this effect was blunted by LLLT. Moreover, endothelial NOS mRNA content increased after LLLT. Plasma nitric oxide metabolites (NOx concentration was increased three days after MI in non-treated rats and increased even further by LLLT treatment. Our data suggest that LLLT diminishes the acute inflammation in the myocardium, reduces infarct size and attenuates left ventricle dysfunction post-MI and increases vasoactive peptides expression and nitric oxide (NO generation.

    Analogs of vasoactive intestinal peptide with cysteine residues incorporated at selected sites within the sequence were prepared by solid phase methods, oxidized to the corresponding cyclic disulfides and purified to homogeneity by preparative HPLC. The cyclic compounds were assayed as smooth muscle relaxants on isolated guinea pig trachea, as bronchodilators in vivo in guinea pigs, and for binding to VIP receptors in guinea pig lung membranes. Of the analogs prepared at the N-terminus, one compound, Ac-[D-Cys6,D-Cys11,Lys12,Nle17,Val26,Th r28]-VIP, was found to be a full agonist with slightly more than one tenth the potency of native VIP. Most other cyclic analogs in the N-terminal region were found to be inactive. A second analog, Ac-[Lys12,Cys17,Val26,Cys28]-VIP, was also found to be a full agonist with potency about one third that of native VIP. Furthermore, this compound was active as a bronchodilator in vivo in guinea pig, but with somewhat diminished potency as compared to native VIP. Strikingly, this cyclic compound was found to have significantly longer duration of action (> 40 min) when compared to an analogous acyclic compound (5 min). The conformational restrictions imposed by formation of the cyclic ring structures may have stabilized the molecule to degradation, thus enhancing the effective duration of action. Analysis of this series of cyclic analogs has also yielded information about the requirements for the receptor-active conformation of VIP.

    While the implementation of evidence-based practices (EBPs) in the treatment of substance use disorders (SUD) has attracted substantial research attention, little consideration has been given to parallel implementation of complementary and alternative medical (CAM) practices. Using data from a nationally representative sample (N = 299) of U.S. substance abuse treatment programs, this study modeled organizational factors falling in the domains of patient characteristics, treatment ideologies, and structural characteristics, associated with the use of art therapy and music therapy. We found that 36.8% of treatment programs offered art therapy and 14.7% of programs offered music therapy. Programs with a greater proportion of women were more likely to use both therapies, and programs with larger proportions of adolescents were more likely to offer music therapy. In terms of other treatment ideologies, programs’ use of Motivational Enhancement Therapy (MET) was positively related to offering art therapy, while use of Contingency Management (CM) was positively associated with offering music therapy. Finally, our findings showed a significant relationship between requiring 12-step meetings and the use of both art therapy and music therapy. With increasing use of CAM in a diverse range of medical settings, and recent federal legislation likely to reduce barriers in accessing CAM, the inclusion of CAM in addiction treatment is growing in importance. Our findings suggest treatment programs may be utilizing art and music therapies to address unique patient needs of women and adolescents. PMID:25514689

    Activation of protein kinase C with phorbol ester modifies cyclic AMP production in several anterior pituitary cell systems. In the GH cell line from a rat pituitary tumor, exposure to phorbol 12-myristate 13-acetate (PMA: 100 nM) for 30 minutes significantly reduces vasoactive intestinal peptide (VIP: 100 nM) stimulated adenylate cyclase (AC) activity in subsequent membrane preparations to 62 + 4% of control (n = 6 independent studies). In contrast, these same membrane preparations respond to forskolin (1 ..mu..M) with significantly more activity, 130 +/- 6% of controls (n = 6 independent studies). Finally, phorbol ester does not block an inhibitory hormone input into the AC system; somatostatin (100 nM) reduction of VIP-stimulated AC activity is not significantly different in membrane preparations from PMA treated and control cells (n = 3 independent studies). These other findings lead the authors to propose that protein kinase C can modify several sites in the AC complex in anterior pituitary cells.

    Chronic cardiovascular disease is associated with air pollution exposure in epidemiology and toxicology studies. Inhaled toxicants can induce changes in serum bioactivity that impact endothelial inflammatory gene expression in vitro and impair vasorelaxation ex vivo, which are common precursors to atherosclerosis. Comparisons between single pollutants and common combustion mixtures, in terms of driving such serum inflammatory and vasoactive effects, have not been characterized. Healthy C57BL/6 mice were exposed to a single 6-h period of contrasting pollutant atmospheres: road dust, mixed vehicle emissions (MVE; a combination of gasoline and diesel engine emissions) particulate matter, mixed vehicle emissions gases, road dust plus ozone, road dust plus MVE, and hardwood smoke. Serum obtained from mice 24 h after these exposures was used as a stimulus to assess inflammatory potential in two assays: incubated with primary murine cerebrovascular endothelial cells for 4 h to measure inflammatory gene expression or applied to naïve aortic rings in an ex vivo myographic preparation. Road dust and wood smoke exposures were most potent at inducing inflammatory gene expression, while MVE atmospheres and wood smoke were most potent at impairing vasorelaxation to acetylcholine. Responses are consistent with recent reports on MVE toxicity, but reveal novel serum bioactivity related to wood smoke and road dust. These studies suggest that the compositional changes in serum and resultant bioactivity following inhalation exposure to pollutants may be highly dependent on the composition of mixtures.

    Although it has long been known that microinjection of the cholinergic agonist carbachol into the medial pontine reticular formation (mPRF) induces a state that resembles rapid eye movement (REM) sleep, it is likely that other transmitters contribute to mPRF regulation of behavioral states. A key...... candidate is the peptide vasoactive intestinal polypeptide (VIP), which innervates the mPRF and induces REM sleep when injected into this region of the brainstem. To begin understanding the cellular mechanisms underlying this phenomenon, we examined the effects of VIP on mPRF cells using whole-cell patch...... conclude that VIP excites mPRF neurons by activation of a sodium current. This effect is mediated at least in part by G-protein stimulation of adenylyl cyclase, cAMP, and protein kinase A. These data suggest that VIP may play a physiological role in REM induction by its actions on mPRF neurons....

    Substance use disorders (SUDs) represent a great barrier to functional recovery for individuals with schizophrenia. It is important to use research on treatment of SUDs in schizophrenia to guide treatment recommendations and program planning. We review studies of pharmacological and psychosocial interventions to treat SUDs in individuals with schizophrenia. The criteria used to select studies for inclusion are (1) the percentage of the sample with a schizophrenia spectrum diagnosis is at least 25%; (2) participants have a comorbid SUD or problem use of substances; (3) an intervention for SUD is provided; (4) a substance use-related outcome is measured; and (5) the study design enabled examination of pre-post outcome measures including open label trials, nonrandomized evaluations (quasi-experimental designs, nonrandom assignment to groups), or randomized controlled trials. There are few psychopharmacology outcomes studies. Most have examined use of antipsychotic medications to treat SUDs in schizophrenia. Several trials have yielded positive findings for naltrexone in reducing drinking compared to placebo in this population. Motivational and cognitive-behavioral interventions are associated with decreased substance use in several trials. Treatment for SUDs is feasible within a range of settings and acceptable to many individuals with schizophrenia. All individuals with schizophrenia should be offered brief or more extended psychosocial interventions that incorporate discussion of personal reasons to change and training in cognitive-behavioral strategies to reduce use, cope with cravings and stress, and avoid relapse. Future research must include larger samples, longitudinal designs, and similar outcome measures across studies.

    Religiousness is reliably associated with lower substance use, but little research has examined whether self-control helps explain why religiousness predicts lower substance use. Building on prior theoretical work, our studies suggest that self-control mediates the relationship between religiousness and a variety of substance-use behaviors. Study 1 showed that daily prayer predicted lower alcohol use on subsequent days. In Study 2, religiousness related to lower alcohol use, which was mediated by self-control. Study 3 replicated this mediational pattern using a behavioral measure of self-control. Using a longitudinal design, Study 4 revealed that self-control mediated the relationship between religiousness and lower alcohol use 6 weeks later. Study 5 replicated this mediational pattern again and showed that it remained significant after controlling for trait mindfulness. Studies 6 and 7 replicated and extended these effects to both alcohol and various forms of drug use among community and cross-cultural adult samples. These findings offer novel evidence regarding the role of self-control in explaining why religiousness is associated with lower substance use.

    Environment and organisms are persistently exposed by a mixture of various substances. However, the current evaluation method is mostly based on an individual substance's toxicity. A systematic toxicity evaluation of heterogeneous substances needs to be established. To demonstrate toxicity assessment of mixture, we chose a group of three typical ingredients in cosmetic sunscreen products that frequently enters ecosystems: benzophenone-3 (BP-3), ethylhexyl methoxycinnamate (EHMC), and titanium dioxide nanoparticle (TiO2 NP). We first determined a range of nominal toxic concentration of each ingredient or substance using Daphnia magna, and then for the subsequent organismal level phenotypic assessment, chose the wild-type zebrafish embryos. Any phenotype change, such as body deformation, led to further examinations on the specific organs of transgenic zebrafish embryos. Based on the systematic toxicity assessments of the heterogeneous substances, we offer a sequential environmental toxicity assessment protocol that starts off by utilizing Daphnia magna to determine a nominal concentration range of each substance and finishes by utilizing the zebrafish embryos to detect defects on the embryos caused by the heterogeneous substances. The protocol showed additive toxic effects of the mixtures. We propose a sequential environmental toxicity assessment protocol for the systematic toxicity screening of heterogeneous substances from Daphnia magna to zebrafish embryo in-vivo models.

    Substance addiction (or drug addiction) is a neuropsychiatric disorder characterized by a recurring desire to continue taking the drug despite harmful consequences. Non-substance addiction (or behavioral addiction) covers pathological gambling, food addiction, internet addiction, and mobile phone addiction. Their definition is similar to drug addiction but they differ from each other in specific domains. This review aims to provide a brief overview of past and current definitions of substance and non-substance addiction, and also touches on the topic of diagnosing drug addiction and non-drug addiction, ultimately aiming to further the understanding of the key concepts needed for a foundation to study the biological and psychological underpinnings of addiction disorders.

  13. Use of 125I-labeled human serum albumin for quantitation of microvascular permeability in rat skin: reevaluation of an old method for studies on substances with an enhancing effect on microvascular permeability

    International Nuclear Information System (INIS)

    Gerdin, B.

    1981-01-01

    A method of determining the leakage of 125I-labeled human serum albumin in the plasma into a standardized area of rat skin to study the effects of intracutaneous application of vasoactive substances on microvascular permeability, was reevaluated. The effect is expressed as a quotient (Q) between the amount of labeled albumin in the test area and that in an area injected with buffer. This calculation is simple and as reliable as more complicated expressions of activity. Within a limited dose range, linear/log dose-response curves can be obtained after application of histamine or bradykinin. Locally injected 125I-labeled human serum albumin is eliminated very slowly from rat skin and determination of the amount of radiolabeled albumin in skin after an intravenous injection therefore represents leakage from the vascular compartments. The potentialities and advantages of this method in pharmacological studies are stressed

  14. Understanding Postdisaster Substance Use and Psychological Distress Using Concepts from the Self-Medication Hypothesis and Social Cognitive Theory.

    Science.gov (United States)

    Alexander, Adam C; Ward, Kenneth D

    2017-11-10

    This article applies constructs from the Self-Medication Hypothesis and Social Cognitive Theory to explain the development of substance use and psychological distress after a disaster. A conceptual model is proposed, which employs a sequential mediation model, identifying perceived coping self-efficacy, psychological distress, and self-medication as pathways to substance use after a disaster. Disaster exposure decreases perceived coping self-efficacy, which, in turn, increases psychological distress and subsequently increases perceptions of self-medication in vulnerable individuals. These mechanisms lead to an increase in postdisaster substance use. Last, recommendations are offered to encourage disaster researchers to test more complex models in studies on postdisaster psychological distress and substance use.

    The primary outcome was to compare the effects of dopamine or epinephrine in severe sepsis on 28-day mortality; secondary outcomes were the rate of healthcare-associated infection, the need for other vasoactive drugs, and the multiple organ dysfunction score. Double-blind, prospective, randomized controlled trial from February 1, 2009, to July 31, 2013. PICU, Hospital Universitário da Universidade de São Paulo, Brazil. Consecutive children who are 1 month to 15 years old and met the clinical criteria for fluid-refractory septic shock. Exclusions were receiving vasoactive drug(s) prior to hospital admission, having known cardiac disease, having already participated in the trial during the same hospital stay, refusing to participate, or having do-not-resuscitate orders. Patients were randomly assigned to receive either dopamine (5-10 μg/kg/min) or epinephrine (0.1-0.3 μg/kg/min) through a peripheral or intraosseous line. Patients not reaching predefined stabilization criteria after the maximum dose were classified as treatment failure, at which point the attending physician gradually stopped the study drug and started another catecholamine. Physiologic and laboratory data were recorded. Baseline characteristics were described as proportions and mean (± SD) and compared using appropriate statistical tests. Multiple regression analysis was performed, and statistical significance was defined as a p value of less than 0.05. Baseline characteristics and therapeutic interventions for the 120 children enrolled (63, dopamine; 57, epinephrine) were similar. There were 17 deaths (14.2%): 13 (20.6%) in the dopamine group and four (7%) in the epinephrine group (p=0.033). Dopamine was associated with death (odds ratio, 6.5; 95% CI, 1.1-37.8; p=0.037) and healthcare-associated infection (odds ratio, 67.7; 95% CI, 5.0-910.8; p=0.001). The use of epinephrine was associated with a survival odds ratio of 6.49. Dopamine was associated with an increased risk of death and healthcare

    Stress is known to cause severe adverse effects in the human gastrointestinal tract including mucosal microbleedings and erosions or even gastric ulceration but the mechanism of these complications has not been fully elucidated. The pathogenesis of stress-induced gastric damage involves the fall in Gastric Blood Flow (GBF), an increase in gastric acid secretion and gastric motility, enhanced adrenergic and cholinergic nerve activity and the rise in gastric mucosal generation of reactive oxygen species. The gastric mucosal defense mechanisms against the deleterious effect of stress include the activation of the hypothalamic-pituitary-adrenal axis which has been linked with glucocorticoids release capable of counteracting of stress-induced gastric lesions. Here we summarize the novel gastroprotective mechanisms against stress damage exhibited by angiotensin-(1-7), the newly discovered metabolite of Renin-Angiotensin System (RAS), the gaseous mediators such as nitric oxide (NO), hydrogen sulfide (H2S) or Carbon Monoxide (CO), and the food intake controlling peptides ghrelin, nesfatin- 1 and apelin possibly acting via brain-gut axis. These bioactive molecules such as RAS vasoactive metabolite angiotensin-(1-7) and appetite peptides have been shown to afford gastroprotective effect against stressinduced gastric lesions mainly mediated by an increase in gastric microcirculation. Gaseous mediators protect the gastric mucosa against stress lesions by mechanism involving the activation of PG/COX and CO/HO-1 biosynthetic pathways, and their anti-inflammatory and anti-oxidizing properties. Thus, these new components add new mechanistic aspects to the common cooperation of NO/NO-synthase, PG/COX systems and vasoactive sensory neuropeptides including CGRP but their gastroprotective efficacy against experimental stress ulcerogenesis requires the confirmation in human clinical trials.

  18. Placental Leucine Aminopeptidase- and Aminopeptidase A- Deficient Mice Offer Insight concerning the Mechanisms Underlying Preterm Labor and Preeclampsia

    Directory of Open Access Journals (Sweden)

    Shigehiko Mizutani

    2011-01-01

    Full Text Available Preeclampsia and preterm delivery are important potential complications in pregnancy and represent the leading causes for maternal and perinatal morbidity and mortality. The mechanisms underlying both diseases remain unknown, thus available treatments (beta2-stimulants and magnesium sulfate are essentially symptomatic. Both molecules have molecular weights less than 5–8 kDa, cross the placental barrier, and thus exert their effects on the fetus. The fetus produces peptides that are highly vasoactive and uterotonic and increase in response to maternal stress and with continued development. Fetal peptides are also small molecules that inevitably leak across into the maternal circulation. Aminopeptidases such as placental leucine aminopeptidase (P-LAP and aminopeptidase A (APA are large molecules that do not cross the placental barrier. We have shown that APA acts as an antihypertensive agent in the pregnant spontaneously hypertensive rat by degrading vasoactive peptides and as a result returns the animal to a normotensive state. P-LAP also acts as an antiuterotonic agent by degrading uterotonic peptides and thus prolongs gestation in the pregnant mouse. Given the ever increasing worldwide incidences of preeclampsia and preterm labor, it is imperative that new agents be developed to safely prolong gestation. We believe that the use of aminopeptidases hold promise in this regard.

  19. Watery diarrhea syndrome in an adult with ganglioneuroma-pheochromocytoma: identification of vasoactive intestinal peptide, calcitonin, and catecholamines and assessment of their biologic activity.

    Science.gov (United States)

    Trump, D L; Livingston, J N; Baylin, S B

    1977-10-01

    A case of adult ganglioneuroma-pheochromocytoma with an associated watery diarrhea syndrome is reported. High levels of vasoactive intestinal peptide (VIP) were found in preoperative serum and in tumor tissue. The serum VIP levels fell to normal, and the watery diarrhae syndrome completely ceased following removal of the tumor. In addition to containing VIP, the tumor was rich in catecholamines, and calcitonin. Peptide hormone-containing extracts and catecholamine extracts from the tumor both activated the adenyl cyclase system and increased lipolytic activity in a preparation of isolated rat fat cells. The findings in this patient further link VIP with neural crest tissues, and suggest the importance of determining catecholamine levels in patients with the watery diarrhea syndrome.

    1982-01-01

    This paper describes a method for localization of substance P receptors in the rat central nervous system using 125 I labeled substance P in an autoradiographic procedure. Particularly high densities of substance P receptors were observed in the olfactory bulb, dentate gyrus, amygdala, superior colliculus, and locus coeruleus. Surprisingly low densities of substance P receptors were found in the substantia nigra pars reticulata, a region which contains high concentrations of substance P

  5. Radioiodination of vasoactive intestinal peptide (VIP)

    International Nuclear Information System (INIS)

    Wang, Y.; Wang, L.; Yin, D.

    2002-01-01

    In recent years, increasing biochemical and radiochemical research has been performed to develop radiolabelled peptides as specific ligands for tumour associated receptors. VIP, a 28-amino acid peptide containing two tyrosines and three lysines, has demonstrated that various tumour cells express significantly higher amounts of VIP-receptors and could be applied to the clinic diagnosis. For these purposes, radiohalogenation of VIP by direct and indirect method was studied. Direct labelling works well for radioiodine but is limited to dehalogenation of labelling products in vivo. Conjugate labelling methods including Boltonhunter and wood reagents were developed but introduction of such a molecule to peptides may lead to the decrease of biological activity in vivo. In order to resolve these problems, N-Succinimidyl-3-(tri-nbutylstannyl) benzoate (ATE) was elected for the radioiodination of VIP and already employed to radioiodination of IgG successfully. The in vitro stability and biological activity would be compared in these two methods. Vasoactive intestinal peptide (VIP) and human immunoglobulin (IgG) were radioiodinated by direct and indirect methods. Iodogen was employed in direct method and N-Succinimidyl-3-(tri-n-butylstannyl) benzoate (ATE) was applied as a prosthetic group in the conjugation labelling. The subject of our study was optimizing the radiohalogenation of IgG and VIP followed by separation and analysis of reaction products. The advantages and disadvantages were illustrated by comparing the in vitro stability and biological activity in these two methods. Na 123 I was prepared by nuclear reaction of 124 Te(p, 2n) 123 I using cyclone-30. More than 95% of radiochemical purity, more than 95% of radionuclide purity and about 100 mCi/mL of radioactivity concentration were obtained. ATE was supplied by Dr. Pozzi and radioiodinated with iodogen and 96% of labelling efficiency was obtained. The stability of radioactive S 125 IB kept well in dark at 4

    Substance abuse has often been associated with committing sex offenses. In this article, the following will be reviewed: 1) studies that assessed substance abuse in sex offenders; 2) differences in substance abuse among different types of sex offenders; 3) differences in substance abuse between sex offenders and nonsexual offenders and substance abuse in the normal population; 4) sex offenders' intoxication at the time of the offense; and 5) differences in intoxication at the time of the offense among different types of sex offenders. Studies will be discussed according to the method they used to assess substance abuse, i.e., file research, screening instruments or semi-structured interviews. This review shows that about half of the sex offenders has a history of substance abuse, a quarter to half of the sex offenders has a history of alcohol misuse and that about one fifth to a quarter of the sex offenders has a history of drug misuse. Furthermore, about a quarter to half of the sex offenders appeared to be intoxicated at the time of the offense. The review results in recommendations for future research. Because of the high prevalence of substance abuse in sex offenders it is advisable to routinely screen for substance abuse and, if necessary, to treat substance abuse. Copyright © 2010 Elsevier Ltd.

    The correlation between noninvasive (oscillometric) blood pressure (NBP) and intra-arterial blood pressure (IAP) in critically ill patients receiving vasoactive medications in a Neurocritical Care Unit has not been systematically studied. The purpose of this study is to examine the relationship between simultaneously measured NBP and IAP recordings in these patients. Prospective observational study of patients (N = 70) admitted to a neurocritical care unit receiving continuous vasopressor or antihypertensive infusions. Paired NBP/IAP observations along with covariate and demographic data were abstracted via chart audit. Analysis was performed using SAS v9.4. A total of 2177 paired NBP/IAP observations from 70 subjects (49% male, 63% white, mean age 59 years) receiving vasopressors (n = 21) or antihypertensive agents (n = 49) were collected. Paired t test analysis showed significant differences between NBP versus IAP readings: ([systolic blood pressure (SBP): mean = 136 vs. 140 mmHg; p blood pressure (DBP): mean = 70 vs. 68 mmHg, p blood pressure (MAP): mean = 86 vs. 90 mmHg, p blood pressures. Pearson correlation coefficients show strong positive correlations for paired MAP (r = 0.82), SBP (r = 0.84), and DBP (r = 0.73) recordings. An absolute NBP-IAP SBP difference of > 20 mmHg was seen in ~ 20% of observations of nicardipine, ~ 25% of observations of norepinephrine, and ~ 35% of observations of phenylephrine. For MAP, the corresponding numbers were ~ 10, 15, and 25% for nicardipine, norepinephrine, and phenylephrine, respectively. Despite overall strong positive correlations between paired NBP and IAP readings of MAP and SBP, clinically relevant differences in blood pressure are frequent. When treating with vasoactive infusions targeted to a specific BP goal, it is important to keep in mind that NBP and IAP values are not interchangeable.

  9. Direct demonstration of guanine nucleotide sensitive receptors for vasoactive intestinal peptide in the anterior lobe of the rat pituitary gland

    International Nuclear Information System (INIS)

    Agui, T.; Matsumoto, K.

    1990-01-01

    The vasoactive intestinal peptide (VIP) receptors were identified on the membranes from the rat anterior pituitary gland with [ 125 I]VIP. The dissociation constant (Kd) and the maximal binding capacity (Bmax) values were estimated from the competitive inhibition data. The Kd and Bmax values were 1.05 +/- 0.75 nM and 103 +/- 11 fmol/mg protein, respectively. The order of molar potency of related peptides to inhibit [ 125 I]VIP binding was VIP greater than peptide histidine isoleucine (PHI) greater than secretin greater than glucagon. Glucagon was not effective to inhibit the binding. [ 125 I]VIP binding was effectively inhibited by the addition of guanine nucleotides. The order of molar potency to inhibit the binding was Gpp(NH)p greater than GTP greater than GDP greater than GMP greater than ATP. These results directly suggest the coupling of VIP receptors with guanine nucleotide binding proteins in the anterior pituitary gland

Pharmacological MRI (phMRI) explores the interaction between brain physiology, neuronal activity and drugs[1]. The BOLD-signal is an indirect method to investigate brain activity by way...... of measuring task-related hemodynamic changes. Pharmacological substances that induce hemodynamic changes can therefore potentially alter the BOLD-signal that in turn falsely can be interpreted as changes in neuronal activity. It is therefore important to characterize possible effects of a pharmacological...... substance on the BOLD-response per see before that substance can be used in an fMRI experiment.

  15. Unusual chemical properties of N-terminal histidine residues of glucagon and vasoactive intestinal peptide

    International Nuclear Information System (INIS)

    Hefford, M.A.; Evans, R.M.; Oda, G.; Kaplan, H.

    1985-01-01

    An N-terminal histidine residue of a protein or peptide has two functional groups, viz., an alpha-amino group and an imidazole group. A new procedure, based on the competitive labeling approach described by Duggleby and Kaplan has been developed by which the chemical reactivity of each functional group in such a residue can be determined as a function of pH. Only very small amounts of material are required, which makes it possible to determine the chemical properties in dilute solution or in proteins and polypeptides that can be obtained in only minute quantities. With this approach, the reactivity of the alpha-amino group of histidylglycine toward 1-fluoro-2,4-dinitrobenzene gave an apparent pK /sub a/ value of 7.64 +/- 0.07 at 37 degrees C, in good agreement with a value of 7.69 +/- 0.02 obtained by acid-base titration. However, the reactivity of the imidazole function gave an apparent pK /sub a/ value of 7.16 +/- 0.07 as compared to the pK /sub a/ value of 5.85 +/- 0.01 obtained by acid-base titration. Similarly, in glucagon and vasoactive intestinal peptide (VIP), apparent pKa values of 7.60 +/- 0.04 and 7.88 +/- 0.18, respectively, were obtained for the alpha-amino of their N-terminal histidine, and pKa values of 7.43 +/- 0.09 and 7.59 +/- 0.18 were obtained for the imidazole function

  16. Vasoactive intestinal peptide and secretin: effects of combined and separate intravenous infusions on bile secretion in man

    International Nuclear Information System (INIS)

    Nyberg, B.; Sonnenfeld, T.; Einarsson, K.

    1991-01-01

    The effects of intravenously administered vasoactive intestinal peptide (VIP) and secretin on bile secretion were studied in 12 patients with complete biliary fistulas. The two peptides were administered both simultaneously and separately. During VIP infusion, bile volume increased by 60%, and during the combined VIP and secretin infursion bile volume increased by another 70%. VIP increased bile bicarbonate concentration by some 30%. Although secretin did not increase the concentration, bicarbonate output increased threefold during secretin infusion but only twofold during VIP infusion. The outputs of bile acids were not significantly affected by the two peptides, whereas the concentration decreased by 40% and 70% after VIP and secretin, respectively. The canalicular bile flow, measured by [ 14 C]erythritol, was unaffected by VIP infusion, whereas secretin alone and the combination of the two peptides increased the canalicular clearance by 80%. The choleretic effect of VIP thus seems to occur only at the ductular level. Secretin exerts its effect at the ductular level and possibly also at the canalicular level. It is concluded that the two peptides have additive effects on the ductular bile flow.. 32 refs., 5 figs., 5 tabs

Multivariate regressions were used to test whether the respondents' use of the REAL strategies by the participants could be predicted by key demographic variables. Separate models were estimated for the frequency of use of each strategy and for different substances. Findings indicate that most adolescents in this sample utilized each of the REAL strategies as well as other strategies to respond to offers of alcohol, cigarettes, or marijuana. Mexican and U.S. youth residing close to the US border appear to use similar drug resistance strategies. Use of the strategies varied considerably by the level of exposure to offers, but only minimally by gender and age. There were no notable differences by socioeconomic status or academic performance. Implications for prevention science, social work practice and social work research are discussed in the context of the bi-national border region and the applicability and prospect for dissemination of U.S. evidence based youth substance use prevention interventions.

    Due to the scarcity of resources for implementing rapid on-site HIV testing, many substance abuse treatment programs do not offer these services. This study sought to determine whether addressing previously identified implementation barriers to integrating on-site rapid HIV testing into the treatment admissions process would increase offer and acceptance rates. Results indicate that it is feasible to integrate rapid HIV testing into existing treatment programs for substance abusers when resources are provided. Addressing barriers such as providing start-up costs for HIV testing, staff training, addressing staffing needs to reduce competing job responsibilities, and helping treatment staff members overcome their concerns about clients' reactions to positive test results is paramount for the integration and maintenance of such programs.

  3. Changes of neurotransmitter levels in the cerebrospinal fluid of children with seizures

    International Nuclear Information System (INIS)

    Greber, S.

    1991-03-01

    In this study the aminoacids are measured in the CSF of children with seizures with a High-Performance Liquid Chromatograph and the peptides Substance P, Neurokinin A, Vasoactive Intestinale Peptide and Calcitoningene related peptide in the same subjects with a radioimmunoassay. The concentrations are related to the duration of seizure and the interval between seizure and puncture. Moreover most children suffer from febrile seizures. The results show an increase of glycine and taurine, two inhibitory amino acids with advancing interval between the seizure, and the puncture. Asparagine decreases with the duration of seizure, while ornithine, cystine and citrulline increase. These results cannot be postulated, because there are only three children with seizures about or equal to 10 minutes. But it can be discussed, that excitatory activity predominates or that central metabolism, the blood-brain-CSF barrier and/or some neurons are disturbed. For the peptides it seems, that the excitatory ones like Substance P, Neurokinin A and Vasoactive Intestinale Peptide increase with seizure susceptibility. That's only the case for seizures without a central focus and therefore maybe a neurochemical expression for a low seizure threshold of the brain. (author)

    The increase rate of utilization of branched-chain amino acids (BCAA) by muscle is reduced to its plasma concentration during prolonged exercise leading to glycogen. BCAA supplementation would reduce the serum activities of intramuscular enzymes associated with muscle damage. To examine the effects of BCAA administration on fatigue substances (serotonin, ammonia and lactate), muscle damage substances (CK and LDH) and energy metabolism substances (FFA and glucose) after endurance exercise. Subjects (n = 26, college-aged males) were randomly divided into an experimental (n = 13, EXP) and a placebo (n = 13, CON) group. Subjects both EXP and CON performed a bout of cycle training (70% VO2max intensity) to exhaustion. Subject in the EXP were administrated BCAA (78ml/kg·w) prior to the bout of cycle exercise. Fatigue substances, muscle damage substances and energy metabolism substances were measured before ingesting BCAAs and placebos, 10 min before exercise, 30 min into exercise, immediately after exercise, and 30 min after exercise. Data were analyzed by two-way repeated measure ANCOVA, correlation and statistical significance was set at p BCAA decreased serum concentrations of the intramuscular enzymes as CK and LDH following exhaustive exercise. This observation suggests that BCAA supplementation may reduce the muscle damage associated with endurance exercise.

    This study investigated the association of academic outcomes, romantic relationships, and substance use (tobacco, marijuana, cocaine) with alcohol dependence in a sample of Latino (N = 1,143) college students. Secondary data analysis was conducted on measures of grade point average in college, relationship satisfaction, drug use, and alcohol dependence. Latino college students who reported alcohol dependency had significant relational dissatisfaction and poor academic outcomes. Thus, lower grade point average and relationship dissatisfaction were associated with alcohol dependence. By focusing specifically on a Mexican American population, this study adds important information to current research regarding the commonality and differences across cultural groups regarding drug use and dependence and further clarifies the risk factors associated with substance use and dependency in a population that is vulnerable for at-risk behaviors. This study also offers insight into potential targets of treatment and intervention for this cultural group.

    Purpose Conduct problems and peer effects are among the strongest risk factors for adolescent substance use and problem use. However, it is unclear to what extent the effects of conduct problems and peer behavior interact, and whether adolescents' capacity to refuse the offer of substances may moderate such links. This study was conducted to examine relationships between conduct problems, close friends' substance use, and refusal assertiveness with adolescents' alcohol use problems, tobacco, and marijuana use. Methods We studied a population-based sample of 1,237 individuals from the Cardiff Study of All Wales and North West of England Twins aged 11–18 years. Adolescent and mother-reported information was obtained. Statistical analyses included cross-sectional and prospective logistic regression models and family-based permutations. Results Conduct problems and close friends' substance use were associated with increased adolescents' substance use, whereas refusal assertiveness was associated with lower use of cigarettes, alcohol, and marijuana. Peer substance use moderated the relationship between conduct problems and alcohol use problems, such that conduct problems were only related to increased risk for alcohol use problems in the presence of substance-using friends. This effect was found in both cross-sectional and prospective analyses and confirmed using the permutation approach. Conclusions Reduced opportunities for interaction with alcohol-using peers may lower the risk of alcohol use problems in adolescents with conduct problems. PMID:20547290

    Aims To assess past-year prevalence rates of substance use behaviors and substance dependence across three major dimensions of sexual orientation (identity, attraction, and behavior) in a large national sample of adult women and men in the United States. Design Data were collected from structured diagnostic face-to-face interviews using the Alcohol Use Disorder and Associated Disabilities Interview Schedule DSM-IV Version (AUDADIS-IV). Setting Prevalence estimates were based on data collected from the 2004–2005 (Wave 2) National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Participants A large national sample of 34,653 adults aged 20 years and older: 52% female, 71% White, 12% Hispanic, 11% African American, 4% Asian, and 2% Native American or other racial/ethnic categories. Findings Approximately 2% of the sample self-identified as lesbian, gay or bisexual; 4% reported at least one lifetime same-sex sexual partner, and 6% reported same-sex sexual attraction. Although non-heterosexual orientation was generally associated with a higher risk of substance use and substance dependence, the majority of sexual minority respondents did not report substance use or meet criteria for DSM-IV substance dependence. There was considerable variation in substance use outcomes across sexual orientation dimensions; these variations were more pronounced among women than among men. Conclusions Results support previous research findings of heightened risk of substance use and substance dependence among some sexual minority groups and point to the need for research that examines reasons for such differences. Results also highlight important gender differences and question previous findings indicating uniformly higher risk for substance dependence among sexual minorities. Risks appear to vary based on gender and how sexual orientation is defined. Findings have implications for prevention and intervention efforts that more effectively target subgroups at greatest

    These days young people use internet as a source of information. Internet offers knowledge that can be used not only for school education but also to obtain information about usage and effects of psychoactive substances. Recent research shows that young people more often use internet websites and chat rooms to exchange knowledge and experience with chemicals and everyday products used as intoxicants, for example: nutmeg, nonprescription medications, metal cleaning liquid or feminine hygiene products. This article shows the extend of knowledge young people can gain from popular internet websites. Information on the web is presented as appealing, attractive and encouraging. From a toxicologist point of view it is extremely important to be familiar with those new threats because more and more often we have to treat young patients with a serious poisoning from usage of experimental intoxicating substances.

    1986-01-01

    Cerebral circulation in the patients with unilateral occlusive cerebrovascular disease (CVD) in chronic stage was evaluated by radionuclide angiography (RNA) using Tc-99m pertechnetate. RNA (each Tc-99m dose = 20 mCi) was repeated in short time interval. Employed parameters were as follows; appearance to peak time (APT), brain transit time (BTT), peak count (PC) and up slope (US). These parameters were calculated from time activity curve (TAC) of ''region of interest'' on each hemisphere and the values obtained in affected side were compared with those of normal side and control hemisphere. Reproducibility of these values were satisfactory in PC and US. The results obtained were as follows: In affected hemisphere, PC and US were significantly reduced, while APT and BTT were not significantly affected. The ratio of PC and US between left and right hemispheres increased in the patients with CVD and the latter was particularly significant to detect the abnormality. Effect of vasoactive drugs such as papaverine, acetazolamide, angiotensin II or methoxamine on these parameters was studied in 24 patients with CVD and 16 patients without CVD. Papaverine and acetazolamide increased significantly PC and US in normal hemisphere of patients without CVD and US in normal hemisphere of patients with CVD, while US in these hemispheres were decreased under high blood pressure induced by angiotensin II and methoxamine. These responses, however, were mild or not detected in the affected hemispheres. (J.P.N.)

    Full Text Available Objective: In this in vitro study, we investigated the vasoactive effects of levobupivacaine and ropivacaine on vascular smooth muscle derived from human umbilical arteries and veins.Material and Methods: The strips were mounted in tissue baths at 37°C continuously gassed with 5% CO2 in oxygen for isometric recording of contractile activity on a polygraph. The endothelium of some tissues was mechanically removed to assess the influence of the endothelium on contractility. The strips were precontracted with serotonin (10-6 M 5-HT; n=7. After obtaining the maximal contraction, responses obtained by adding levobupivacaine and ropivacaine (10-9-10-4 M; n=7 cumulatively were recorded. Contractions were expressed as the (% of 5HT maximal response percentage of 5 HT’s maximal response.Results: Both levobupivacaine and ropivacaine induce a concentration-dependent contraction in the smooth muscle cells of umbilical arteries and veins. Maximum contractile response (Emax of levobupivacaine (79.2±2.5, 71.1±2.6 was higher than ropivacaine (68.4±2, 36.2±2.8 on both umbilical arteries and veins. There were no statistically significant differences between contraction responses of endothelium-intact and endothelium-denuded tissues. Conclusion: The results suggest that, in high concentrations, levobupivacaine and ropivacaine may affect umbilical blood flow by contracting the umbilical artery and vein, thus reducing fetal blood flow.

    This report discusses pricing of emissions to air of several harmful substances. It combines ranking indices for environmentally harmful substances with economic valuation data to yield price estimates. The ranking methods are discussed and a relative index established. Given the relative ranking of the substances, they all become valued by assigning a value to one of them, the `anchor` substance, for which lead is selected. Valuations are provided for 19 hazardous substances that are often subject to environmental regulations. They include dioxins, TBT, etc. The study concludes with a discussion of other categories of substances as well as uncertainties and possible refinements. When the valuations are related to CO, NOx, SOx and PM 10, the index system undervalues these pollutants as compared to other studies. The scope is limited to the outdoor environment and does not include global warming and eutrophication. The indices are based on toxicity and so do not apply to CO{sub 2} or other substances that are biologically harmless. The index values are not necessarily valid for all countries and should be considered as preliminary. 18 refs., 6 tabs.

    All classes of iodinated water-soluble radiographic contrast media (RCM) are vasoactive with the iso-osmolar dimers inducing the least changes in the vascular tone. The mechanisms responsible for RCM-induced changes in the vascular tone are not fully understood and could be multifactorial. A direct effect on the vascular smooth muscle cells causing alterations in the ion exchanges across the cell membrane is thought to be an important factor in RCM-induced vasodilatation. The release of the endogenous vasoactive mediators adenosine and endothelin may also play a crucial role in the haemodynamic effects of RCM particularly in the kidney. In addition, the effects of RCM on blood rheology can cause a reduction in the blood flow in the microcirculation. The purpose of this review is to discuss the pathophysiology of the haemodynamic effects of RCM and to offer some insight into the biology of the endothelium and vascular smooth muscle cells as well as the pharmacology of the important vasoactive mediators endothelin and adenosine

    To improve awareness and knowledge of problematic substance use in pregnancy and to provide evidence-based recommendations for the management of this challenging clinical issue for all health care providers. This guideline reviews the use of screening tools, general approach to care, and recommendations for clinical management of problematic substance use in pregnancy. Evidence-based recommendations for screening and management of problematic substance use during pregnancy and lactation. Medline, PubMed, CINAHL, and The Cochrane Library were searched for articles published from 1950 using the following key words: substance-related disorders, mass screening, pregnancy complications, pregnancy, prenatal care, cocaine, cannabis, methadone, opioid, tobacco, nicotine, solvents, hallucinogens, and amphetamines. Results were initially restricted to systematic reviews and randomized control trials/controlled clinical trials. A subsequent search for observational studies was also conducted because there are few RCTs in this field of study. Articles were restricted to human studies published in English. Additional articles were located by hand searching through article reference lists. Searches were updated on a regular basis and incorporated in the guideline up to December 2009. Grey (unpublished) literature was also identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on the Preventive Health Care. Recommendations for practice were ranked according to the method described in that report (Table 1).

    mental illness were commonly identified correlates of substance use.Our understanding of substance use among forced migrants remains limited, particularly regarding persons displaced due to disasters, development and deportation. Despite a growing body of work among refugee-background populations, few studies include refugees in low and middle-income countries, where over 80% of the global refugee population resides. Findings suggest a need to integrate substance use prevention and treatment into services offered to forced migrants, particularly in camp settings. Efforts to develop and evaluate interventions to reduce substance use and related harms are needed.

    To present the development of a multidisciplinary controlled substances committee and describe its effectiveness in relation to prescribers' acceptance of committee recommendations, the number of premature deaths associated with controlled substances, and prescribers' need for education on controlled substances. A patient-centered medical home and accountable care organization in Maine that serves more than 60,000 patients across a large rural area, 70% of whom are classified as lower income. A multidisciplinary group of prescribers and PharmD residents created a committee to influence organizational culture regarding controlled substances. The Controlled Substances Initiative Committee (CSIC) updated institutional policies, developed provider education, and made personalized patient recommendations to prescribers. The primary outcome was average change in daily morphine equivalent dose (MED) in patients for whom CSIC recommended a dose reduction to the patient's prescriber. Secondary outcomes included the proportion of patients who died of a known overdose or suspected drug-related death during 2012-2013 or 2013-2014. In addition, prescriber beliefs about controlled substances were measured via a needs assessment. The average daily MED for patients whom CSIC recommended dose reduction was lower after 3 months compared with at baseline (175.5 ± 344.3 mg vs. 292.7 ± 466.5 mg; P vs. 11.1%; P = 1.00). However, a greater number of patients had a suspected drug-related death during 2013-2014 compared with during 2012-2013 (0% vs. 27.3%; P = 0.05). A multidisciplinary controlled substances committee may improve patient safety and outcomes by offering prescriber support and helping alter prescribing culture.

    1990-01-01

    Vasoactive intestinal peptide (VIP) has been implicated as a physiological PRL-releasing factor; however, characterization of VIP receptors on normal pituitaries using radioligand-binding methods has been problematic. In this study we demonstrated specific receptors for VIP in anterior pituitary glands of female rats using HPLC-purified monoiodinated [Tyr(125I)10]VIP. Binding of VIP was reversible, saturable to receptor and radioligand, regulated by guanine nucleotides, and dependent on time and temperature. Scatchard analysis of competitive binding studies indicated high and low affinity binding sites, with equilibrium dissociation constants (Kd) of 0.19 +/- 0.03 and 28 +/- 16 nM, respectively. The corresponding maximum numbers of binding sites were 158 +/- 34 fmol/mg and 11.7 +/- 6.9 pmol/mg. Binding was specific, as peptides with structural homology to VIP were less than 100th as potent as VIP. The rank order of potency of the peptides tested was VIP greater than rat (r) peptide histidine isoleucine = human (h) PHI greater than rGRF greater than bovine GRF = porcine PHI = VIP-(10-28) greater than hGRF greater than secretin greater than apamin greater than glucagon. Radioligand binding was associated primarily with lactotrope-enriched fractions prepared by unit gravity sedimentation of dispersed anterior pituitary cells. VIP stimulated PRL release from cultured rat anterior pituitary cells, with an ED50 of 1 nM. These results, comprising the first identification of specific VIP receptors in normal rat anterior pituitary tissue using radioligand-binding methods, provide additional support for a biological role of VIP in lactotrope function

  5. Extracellular histones disarrange vasoactive mediators release through a COX-NOS interaction in human endothelial cells.

    2017-08-01

    Extracellular histones are mediators of inflammation, tissue injury and organ dysfunction. Interactions between circulating histones and vascular endothelial cells are key events in histone-mediated pathologies. Our aim was to investigate the implication of extracellular histones in the production of the major vasoactive compounds released by human endothelial cells (HUVECs), prostanoids and nitric oxide (NO). HUVEC exposed to increasing concentrations of histones (0.001 to 100 μg/ml) for 4 hrs induced prostacyclin (PGI2) production in a dose-dependent manner and decreased thromboxane A2 (TXA2) release at 100 μg/ml. Extracellular histones raised cyclooxygenase-2 (COX-2) and prostacyclin synthase (PGIS) mRNA and protein expression, decreased COX-1 mRNA levels and did not change thromboxane A2 synthase (TXAS) expression. Moreover, extracellular histones decreased both, eNOS expression and NO production in HUVEC. The impaired NO production was related to COX-2 activity and superoxide production since was reversed after celecoxib (10 μmol/l) and tempol (100 μmol/l) treatments, respectively. In conclusion, our findings suggest that extracellular histones stimulate the release of endothelial-dependent mediators through an up-regulation in COX-2-PGIS-PGI2 pathway which involves a COX-2-dependent superoxide production that decreases the activity of eNOS and the NO production. These effects may contribute to the endothelial cell dysfunction observed in histone-mediated pathologies. © 2017 The Authors.

    This study investigated athlete knowledge of the World Anti-doping Agency (WADA) Prohibited Substances List and the effects of four well-known performance enhancing substances (PES). A sample of 1925 elite and sub-elite athletes (mean age 20.6 years) completed a questionnaire about the banned status of 30 substances/methods and their knowledge of the effects of amphetamines, anabolic steroids, growth hormone and erythropoietin. Athletes showed limited understanding of the WADA Prohibited Substances List, scoring 32.2% correct, 36.3% incorrect, and 31.4% indicated they did not know the status of 30 substances. Responses of >50% correct were given for only eight substances/method: anabolic steroids, amphetamines, blood doping, erythropoietin, caffeine, vitamins/minerals, protein powders and iron. Athletes demonstrated moderate knowledge of the desired effects of the four PES (49% correct), but poor knowledge of their adverse effects (29% correct). Age, sex, ethnicity, professional/amateur status, and current competition level were significant predictors of the number of correct responses (r 2  = 0.16, p wide range of substances and PES. Better targeted drug education towards younger and non-professional athletes and evaluation of current anti-doping programs are warranted. Copyright © 2018 Elsevier B.V. All rights reserved.

  9. Substance Use Stigma: Reliability and validity of a theory-based scale for substance-using populations*

    Background Substance use disorders consistently rank among the most stigmatized conditions worldwide. Thus, substance use stigma fosters health inequities among persons with substance use disorders and remains a key barrier to successful screening and treatment efforts. Current efforts to measure substance use stigma are limited. This study aims to advance measurement efforts by drawing on stigma theory to develop and evaluate the Substance Use Stigma Mechanisms Scale (SU-SMS). The SU-SMS was designed to capture enacted, anticipated, and internalized substance use stigma mechanisms among persons with current and past substance use disorders, and distinguish between key stigma sources most likely to impact this target population. Methods This study was a cross-sectional evaluation of the validity, reliability, and generalizability of the SU-SMS across two independent samples with diverse substance use and treatment histories. Results Findings support the structural and construct validity of the SU-SMS, suggesting the scale was able to capture enacted, anticipated, and internalized stigma as distinct stigma experiences. It also further differentiated between two distinct stigma sources (family and healthcare providers). Analysis of these mechanisms and psychosocial metrics suggests that the scale is also associated with other health-related outcomes. Furthermore, the SU-SMS demonstrated high levels of internal reliability and generalizability across two independent samples of persons with diverse substance use disorders and treatment histories. Conclusion The SU-SMS may serve as a valuable tool for better understanding the processes through which substance use stigma serves to undermine key health behaviors and outcomes among persons with substance use disorders.

    1987-01-01

    The iodination of vasoactive intestinal peptide (VIP) was studied, using a variety of enzymatic and chemical iodination methods. Reversed phase high performance liquid chromatography (HPLC) was used to purify the reaction products. The lactoperoxidase-glucose oxidase method gave excellent results in terms of reproducibility, iodine incorporation, and yield of the non-oxidized products [Tyr(I)10]VIP and [Tyr(I)22]VIP, and was used to prepare both 125 I and 127 I labelled derivatives. In both cases, direct application to HPLC and a single column system were used. Although the oxidized peptides [Tyr(I)10,Met(O)17]VIP and [Tyr(I)22,Met(O)17]VIP could be generated to varying degrees directly by iodination of VIP, these were most conveniently prepared by iodination of [Met(O)17]VIP. Iodinated derivatives of the homologous peptides PHI and PHM were likewise prepared by rapid, one-step HPLC procedures. The site and degree of iodination were determined by HPLC peptide mapping of tryptic digests and amino acid analyses, and in the case of [Tyr(I)10]VIP also by sequencing. The vasorelaxant activities of the iodinated peptides in bovine cerebral artery preparations did not differ significantly from those of the corresponding noniodinated peptides, with the exception of [Tyr(I)10,Met(O)17]VIP and [Tyr(I)22,Met(O)17]VIP which, unlike [Met(O)17]VIP itself, had slightly lower potency than VIP

  11. Current challenges and problems in the field of new psychoactive substances in Germany from a law enforcement perspective.

    Science.gov (United States)

    Duffert, Anna

    2014-01-01

    Over the last few years, a range of so-called new psychoactive substances (NPS) have established themselves on the German recreational drug scene, causing increased concern. At the same time, a great number of Internet shops have come into existence offering these substances for sale online, ensuring a high level of availability. A number of these substances derived from pharmaceutical research which did not result in marketing authorization, presumably due to unfavourable properties. There are hardly any reliable data on long-term health damage, addictive potential, and other aspects of these scientifically unexplored substances. A number of fatal intoxications have also become known. As a rule, the mostly young consumers do not know what substance they are taking and in what concentration, thus exposing themselves to incalculable health risks and consequences. The punishability of the handling of NPS depends on the actual content: the Narcotic Drugs Act (BtMG) is applicable if a product contains narcotic drugs. If similarly effective substances are contained, which are not classified as narcotic drugs, the (penal) provisions of the Medicinal Products Act might be applicable, if the product has a pharmaceutical effect. Experience gained so far has shown that manufacturers of these intoxicating substances react immediately to inclusions in the German BtMG and put new substances on the market which are chemically similar to the known substances thus circumventing legislation. In view of the immense variety of NPS and the enormous profits derived from their sale, an end to this development is not in sight. Copyright © 2014 John Wiley & Sons, Ltd.

    2017-10-01

    To study how substance use disorder (SUD) treatment providers respond to changes in economic conditions. 2000-2012 National Survey of Substance Abuse Treatment Services (N-SSATS) which contains detailed information on specialty SUD facilities in the United States. We use fixed-effects regression to study how changes in economic conditions, proxied by state unemployment rates, impact treatment setting, accepted payment forms, charity care, offered services, special programs, and use of pharmacotherapies by specialty SUD treatment providers. Secondary data analysis in the N-SSATS. Our findings suggest a one percentage point increase in the state unemployment rate is associated with a 2.5% reduction in outpatient clients by non-profit providers and a 1.8% increase in the acceptance of private insurance as a form of payment overall. We find no evidence that inpatient treatment, the provision of charity care, offered services, or special programs are impacted by changes in the state unemployment rate. However, a one percentage point increase in the state unemployment rate leads to a 2.5% increase in the probability that a provider uses pharmacotherapies to treat addiction. Deteriorating economic conditions may increase financial pressures on treatment providers, prompting them to seek new sources of revenue or to change their care delivery models.

    2011-01-01

    This study explored relationships between several hypothesized dimensions of gender identity and substance use outcomes within a non-probability sample of adolescents in Monterrey, Mexico. Based on Mexican concepts of machismo and marianismo, four gender identity constructs were measured: aggressive masculinity, assertive masculinity, affective femininity and submissive femininity. The study assessed how well these gender identity measures predicted substance use behaviors, substance use intentions, expectancies, and normative approval, and exposure and vulnerability to substance offers. Data were drawn from questionnaires completed by 327 students from 2 Monterrey secondary schools. Multivariate ordered logistic and linear regression analyses, adjusted for school level effects, indicated that aggressive masculinity was associated with higher risk of drug use on most outcomes, while affective femininity was associated with lower risk on selected outcomes. Assertive masculinity was associated with only one of the outcomes examined and submissive femininity with none of them. Most gender identity effects persisted after controlling for biological sex, academic performance, age, and other gender identity measures. For two of the outcomes, the gender identity measures had significantly stronger effects for males than for females. The findings are interpreted in light of males’ higher risk for drug use and changes in gender roles and gendered behavior that are now occurring in Mexico as in the U.S. PMID:18329826

    To report on the development of a questionnaire to screen for hazardous substance use in pregnant women and to compare the performance of the questionnaire with other drug and alcohol measures. Pregnant women were administered a modified TWEAK (Tolerance, Worried, Eye-openers, Amnesia, K[C] Cut Down) questionnaire, the 4Ps Plus questionnaire, items from the Addiction Severity Index, and two questions about domestic violence (N=2,684). The sample was divided into "training" (n=1,610) and "validation" (n=1,074) subsamples. We applied recursive partitioning class analysis to the responses from individuals in the training subsample that resulted in a three-item Substance Use Risk Profile-Pregnancy scale. We examined sensitivity, specificity, and the fit of logistic regression models in the validation subsample to compare the performance of the Substance Use Risk Profile-Pregnancy scale with the modified TWEAK and various scoring algorithms of the 4Ps. The Substance Use Risk Profile-Pregnancy scale is comprised of three informative questions that can be scored for high- or low-risk populations. The Substance Use Risk Profile-Pregnancy scale algorithm for low-risk populations was mostly highly predictive of substance use in the validation subsample (Akaike's Information Criterion=579.75, Nagelkerke R=0.27) with high sensitivity (91%) and adequate specificity (67%). The high-risk algorithm had lower sensitivity (57%) but higher specificity (88%). The Substance Use Risk Profile-Pregnancy scale is simple and flexible with good sensitivity and specificity. The Substance Use Risk Profile-Pregnancy scale can potentially detect a range of substances that may be abused. Clinicians need to further assess women with a positive screen to identify those who require treatment for alcohol or illicit substance use in pregnancy. III.

    2008-11-01

    For the first time since the year 2000 the number of death due to substance abuse of illegal drugs has increased in Germany in 2007 (+8 % compared to 2006). Emergency situations due to drug abuse are frequent, particular in big cities. They may be, however, difficult to diagnose and/or treat for an emergency physician on scene because of a lack of diagnostic tools, the local and personal surroundings, and the unknown number and nature of drugs. Many drug intoxications must be considered suicidal. On the other hand, drug intoxications may mask (other) life-threatening conditions. Emergency situations due to withdrawal offer the possibility to motivate patients to take advantage of specialist-guided abstinence programs.

  1. Radioiodination of humic substances

    Energy Technology Data Exchange (ETDEWEB)

    Franke, K.; Kupsch, H. [Inst. of Interdisciplinary Isotope Research, Leipzig (Germany)

    2010-07-01

    The known IODO-GEN trademark -method was adapted for radiolabeling of humic and fulvic acids with {sup 131}I. The water insoluble oxidizing agent 1,3,4,6tetrachloro-3{alpha},6{alpha}-diphenylglycoluril (IODO-GEN trademark) forms an iodous ion species (I{sup +}), which undergoes an electrophilic I/H-substitution on aromatic moieties of the humic and fulvic acids. This method offers mild conditions with a lesser extent of oxidative alterations of the target molecule, accompanied by an easy handling due to the virtual water-insolubility of the oxidizing agent. The method was optimized and different techniques were tested for the purification of the radioiodinated humic material. The yield of the labeling procedure varies between 45 and 75% depending on the provenance of the humic material and the applied purification method. A specific activity up to 40 MBq/mg was achieved. Furthermore, the known inherent photo-susceptibility of the iodinated humic substance and the influence of reducing agents were verified. An additional release of {sup 131}I up to 20% and up to 35%, respectively were observed. (orig.)

  2. Psychopathology in Substance Use Disorder Patients with and without Substance-Induced Psychosis

    Directory of Open Access Journals (Sweden)

    Simon Zhornitsky

    2015-01-01

    Full Text Available Background. Substance-induced psychotic disorder (SIPD is a diagnosis constructed to distinguish substance-induced psychotic states from primary psychotic disorders. A number of studies have compared SIPD persons with primary psychotic patients, but there is little data on what differentiates substance use disorder (SUD individuals with and without SIPD. Here, we compared psychopathology, sociodemographic variables, and substance use characteristics between SUD patients with and without SIPD. Methods. A retrospective chart review was conducted on newly admitted patients at a rehabilitation centre between 2007 and 2012. Results. Of the 379 patients included in the study, 5% were diagnosed with SIPD n=19 and 95% were diagnosed with SUDs without SIPD n=360. More SIPD patients reported using cannabis and psychostimulants, and fewer SIPD patients reported using alcohol than SUDs patients without SIPD. SIPD patients scored higher on the “schizophrenia nuclear symptoms” dimension of the SCL-90R psychoticism scale and exhibited more ClusterB personality traits than SUD patients without SIPD. Discussion. These data are consistent with previous studies suggesting that psychopathology, substance type, and sociodemographic variables play important role in the development of SIPD. More importantly, the results highlight the need for paying greater attention to the types of self-reported psychotic symptoms during the assessment of psychotomimetic effects associated with psychoactive substances.

  3. Receptors for sensory neuropeptides in human inflammatory diseases: Implications for the effector role of sensory neurons

    Glutamate and several neuropeptides are synthesized and released by subpopulations of primary afferent neurons. These sensory neurons play a role in regulating the inflammatory and immune responses in peripheral tissues. Using quantitative receptor autoradiography we have explored what changes occur in the location and concentration of receptor binding sites for sensory neurotransmitters in the colon in two human inflammatory diseases, ulcerative colitis and Crohn's disease. The sensory neurotransmitter receptors examined included bombesin, calcitonin gene related peptide-alpha, cholecystokinin, galanin, glutamate, somatostatin, neurokinin A (substance K), substance P, and vasoactive intestinal polypeptide. Of the nine receptor binding sites examined only substance P binding sites associated with arterioles, venules and lymph nodules were dramatically up-regulated in the inflamed tissue. These data suggest that substance P is involved in regulating the inflammatory and immune responses in human inflammatory diseases and indicate a specificity of efferent action for each sensory neurotransmitter in peripheral tissues

  4. Pubertal timing and substance use: associations between and within families across late adolescence.

    Dick, D M; Rose, R J; Viken, R J; Kaprio, J

    2000-03-01

    In the present study, between-family analyses of data from adolescent twin girls offer new evidence that early menarche is associated with earlier initiation and greater frequency of smoking and drinking. The role of personality factors and peer relationships in that association was investigated, and little support was found for their involvement. Novel within-family analyses replicating associations of substance use with pubertal timing in contrasts of twin sisters selected for extreme discordance for age at menarche are reported. Within-family replications demonstrated that the association of pubertal timing with substance use cannot be explained solely by between-family confounds. Within-family analyses demonstrated contextual modulation of the influence of pubertal timing: Its impact on drinking frequency is apparent only among girls in urban settings. Sibling comparisons illustrate a promising analytic tool for studying diverse developmental outcomes.

    Conclusion: In this study, the β-EP, VIP, 5-HT and NE contents in ITP mice injected with GP-APS were changed by prednison. It shows that prednison as the first-line therapy for ITP with effective hemostasis function is likely to increasing the contents of VIP and 5-HT. These results suggest the therapeutic value of prednison for the treatment of ITP.

    The abuse of substances available to anesthesiologists in their workspace is a potentially lethal occupational hazard. Our primary objective was to define the prevalence of substance abuse cases among Canadian anesthesiologists at university-affiliated hospitals. Our secondary aim was to describe the current management of confirmed cases, rehabilitation procedures being offered, and preventative strategies being employed. We conducted a cross-sectional electronic survey of all Canadian anesthesia residency program directors and site chiefs at university-affiliated hospitals. Data analysis was performed using descriptive statistics. The survey response rate was 54% (53/98). Substance abuse was reported as 1.6% for residents and 0.3% for clinical fellows over a ten-year period ending in June 2014. Fentanyl was abused in nine of 24 reported cases. At present, one of 22 respondents (4.5%) reported a formal education program on substance abuse for faculty members, and 72% described mandatory education for residents. The majority of participants did not perceive substance abuse as a growing problem. Seventy-one percent of respondents indicated that methods for controlled-drug handling had changed in the previous ten years; however, 66% did not think that the incidence of controlled substance abuse could be decreased further by more stringent measures. Only 21% of respondents supported the introduction of random urine drug testing. The prevalence of substance abuse among Canadian anesthesiologists and the substances abused appear comparable with data from the United States, with residents being the group most often affected. Early recognition and treatment of chemically dependent anesthesiologists remain imperfect.

  10. Substance abuse and child maltreatment.

    Science.gov (United States)

    Wells, Kathryn

    2009-04-01

    Pediatricians and other medical providers caring for children need to be aware of the dynamics in the significant relationship between substance abuse and child maltreatment. A caregiver's use and abuse of alcohol, marijuana, heroin, cocaine, methamphetamine, and other drugs place the child at risk in multiple ways. Members of the medical community need to understand these risks because the medical community plays a unique and important role in identifying and caring for these children. Substance abuse includes the abuse of legal drugs as well as the use of illegal drugs. The abuse of legal substances may be just as detrimental to parental functioning as abuse of illicit substances. Many substance abusers are also polysubstance users and the compounded effect of the abuse of multiple substances may be difficult to measure. Often other interrelated social features, such as untreated mental illness, trauma history, and domestic violence, affect these families.

  11. Effects and risks associated with novel psychoactive substances: mislabeling and sale as bath salts, spice, and research chemicals.

    Hohmann, Nicolas; Mikus, Gerd; Czock, David

    2014-02-28

    The number of newly reported psychoactive substances in Europe is now higher than ever. In order to evade legal restrictions, old and novel psychoactive substances from medical research and their derivatives are commonly mislabeled as "not for human consumption" and offered for sale on the Internet and elsewhere. Such substances are widely taken by young people as "club drugs." Their consumption must be considered in the differential diagnosis of psychiatric, neurological, cardiovascular, or metabolic disturbances of unclear origin in a young patient. Selective review of pertinent literature retrieved by a PubMed search, including publications by government-sponsored organizations. From 2010 to 2012, 163 substances were reported to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), mostly either synthetic cannabinoids (39.3%) or synthetic cathinones (16.6%). Synthetic cannabinoids alter mood and perception; intoxications cause agitation, tachy cardia, and arterial hypertension. Synthetic cathinones are hallucinogenic stimulants with predominantly cardiovascular and psychiatric side effects. Severe intoxications cause serotonin syndrome and potentially fatal rhabdomyolysis. Substances in either of these classes often escape detection in screening tests. Young persons who present with agitation and cardiovascular and/or psychiatric manifestations of unclear origin and whose drug screening tests are negative may be suffering from an intoxication with a novel psychoactive substance. Physicians should know the classes of such substances and their effects. Targeted toxicological analysis can be carried out in a toxicology laboratory or a facility for forensic medicine.

  12. When acute-stage psychosis and substance use co-occur: differentiating substance-induced and primary psychotic disorders.

    Caton, C L; Samet, S; Hasin, D S

    2000-09-01

    Substances such as alcohol, cocaine, amphetamine, and cannabis can produce psychotic reactions in individuals who are otherwise free of serious mental illness. However, persons with primary psychotic disorders, such as schizophrenia and bipolar disorder, who use these substances often present for treatment with signs and symptoms similar to those whose psychosis resulted from the use of drugs alone. While it is often difficult to distinguish substance-induced from primary psychoses, especially early in the course of treatment, this differential diagnosis has important implications for treatment planning. To help clinicians distinguish these two types of presentations, the authors first review the types of psychotic symptoms that can co-occur with substance use. They discuss the prevalence and patterns of substance use that have been found in patients with schizophrenia and other primary psychotic disorders and review the negative outcomes associated with substance use in this population. The prevalence of and types of symptoms and problems associated with psychotic symptoms that occur as a result of substance use alone are also reviewed. The authors describe assessment procedures for differentiating substance-induced and primary psychotic disorders. They stress the importance of accurately establishing the temporal relationship between the substance use and the onset and continuation of psychotic symptoms in making a differential diagnosis, as well as the importance of being familiar with the types of psychological symptoms that can occur with specific substances. The authors review the utility and limitations of a number of diagnostic instruments for assessing patients with co-occurring psychosis and substance use problems, including The Addiction Severity Index, The Michigan Alcohol Screening Test, and diagnostic interviews such as the Schedule for Affective Disorders and Schizophrenia and the Structured Clinical Interview for DSM. They then discuss the

    Given the high prevalence of smoking among substance use disorder (SUD) patients, the specialty SUD treatment system is an important target for adoption and implementation of tobacco cessation (TC) services. While research has addressed the impact of tobacco control on individual tobacco consumption, largely overlooked in the literature is the potential impact of state tobacco control policies on availability of services for tobacco cessation. This paper examines the association between state tobacco control policy and availability of TC services in SUD treatment programs in the United States. State tobacco control and state demographic data (n=51) were merged with treatment program data from the 2012 National Survey of Substance Abuse Treatment Services (n=10.413) to examine availability of TC screening, counseling and pharmacotherapy services in SUD treatment programs using multivariate logistic regression models clustered at the state-level. Approximately 60% of SUD treatment programs offered TC screening services, 41% offered TC counseling services and 26% offered TC pharmacotherapy services. Results of multivariate logistic regression showed the odds of offering TC services were greater for SUD treatment programs located in states with higher cigarette excise taxes and greater spending on tobacco prevention and control. Findings indicate cigarette excise taxes and recommended funding levels may be effective policy tools for increasing access to TC services in SUD treatment programs. Coupled with changes to insurance coverage for TC under the Affordable Care Act, state tobacco control policy tools may further reduce tobacco use in the United States. Published by Elsevier Ltd.

    The use of dietary supplements is increasing among athletes, year after year. Related to the high rates of use, unintentional doping occurs. Unintentional doping refers to positive anti-doping tests due to the use of any supplement containing unlisted substances banned by anti-doping regulations and organizations, such as the World Anti-Doping Agency (WADA). The objective of this review is to summarize the presence of unlabeled doping substances in dietary supplements that are used in sports. A review of substances/metabolites/markers banned by WADA in ergonutritional supplements was completed using PubMed. The inclusion criteria were studies published up until September 2017, which analyzed the content of substances, metabolites and markers banned by WADA. 446 studies were identified, 23 of which fulfilled all the inclusion criteria. In most of the studies, the purpose was to identify doping substances in dietary supplements. Substances prohibited by WADA were found in most of the supplements analyzed in this review. Some of them were prohormones and/or stimulants. With rates of contamination between 12 and 58%, non-intentional doping is a point to take into account before establishing a supplementation program. Athletes and coaches must be aware of the problems related to the use of any contaminated supplement and should pay special attention before choosing a supplement, informing themselves fully and confirming the guarantees offered by the supplement.

  17. Demographic and Mental Health Characteristics of Individuals Who Present to Community Health Clinics With Substance Misuse

    Full Text Available Introduction: Community health clinics (CHCs are an opportune setting to identify and treat substance misuse. This study assessed the characteristics of patients who presented to a CHC with substance misuse. Methods: Personnel at a large CHC administered a 5-question screener to patients between June 3, 2014, and January 15, 2016, to assess past 3-month alcohol use, prescription opioid misuse, or illicit drug use. We stratified screen-positive patients into 4 diagnostic groups: (1 probable alcohol use disorder (AUD and no comorbid opioid use disorder (OUD; (2 probable heroin use disorder; (3 probable prescription OUD, with or without comorbid AUD; and (4 no probable substance use disorder. We describe substance use and mental health characteristics of screen-positive patients and compare the characteristics of patients in the diagnostic groups. Results: Compared to the clinic population, screen-positive patients (N = 733 included more males ( P < .0001 and had a higher prevalence of probable bipolar disorder ( P < .0001 and schizophrenia ( P < .0001. Eighty-seven percent of screen-positive patients had probable AUD or OUD; only 7% were currently receiving substance use treatment. The prescription opioid and heroin groups had higher rates of past bipolar disorder and consequences of mental health conditions than the alcohol only or no diagnosis groups ( P < .0001. Conclusions: Patients presenting to CHCs who screen positive for alcohol or opioid misuse have a high likelihood of having an AUD or OUD, with or without a comorbid serious mental illness. Community health clinics offering substance use treatment may be an important resource for addressing unmet need for substance use treatment and comorbid mental illness.

    Ream, Geoffrey L; Elliott, Luther C; Dunlap, Eloise

    2011-10-01

    This study tested the hypothesis that playing video games while using or feeling the effects of a substance--referred to herein as "concurrent use"-is related to substance use problems after controlling for substance use frequency, video gaming as an enthusiastic hobby, and demographic factors. Data were drawn from a nationally representative online survey of adult video gamers conducted by Knowledge Networks, valid n = 2,885. Problem video game playing behavior was operationalized using Tejeiro Salguero and Bersabé Morán's 2002 problem video game play (PVP) measure, and measures for substance use problems were taken from the National Survey of Drug Use and Health (NSDUH). Separate structural equation modeling analyses were conducted for users of caffeine, tobacco, alcohol, and marijuana. In all four models, concurrent use was directly associated with substance use problems, but not with PVP. Video gaming as an enthusiastic hobby was associated with substance use problems via two indirect paths: through PVP for all substances, and through concurrent use for caffeine, tobacco, and alcohol only. Results illustrate the potential for "drug interaction" between self-reinforcing behaviors and addictive substances, with implications for the development of problem use.

  20. Mast cell chymase reduces the toxicity of Gila monster venom, scorpion venom, and vasoactive intestinal polypeptide in mice

    Mast cell degranulation is important in the pathogenesis of anaphylaxis and allergic disorders. Many animal venoms contain components that can induce mast cell degranulation, and this has been thought to contribute to the pathology and mortality caused by envenomation. However, we recently reported evidence that mast cells can enhance the resistance of mice to the venoms of certain snakes and that mouse mast cell–derived carboxypeptidase A3 (CPA3) can contribute to this effect. Here, we investigated whether mast cells can enhance resistance to the venom of the Gila monster, a toxic component of that venom (helodermin), and the structurally similar mammalian peptide, vasoactive intestinal polypeptide (VIP). Using 2 types of mast cell–deficient mice, as well as mice selectively lacking CPA3 activity or the chymase mouse mast cell protease-4 (MCPT4), we found that mast cells and MCPT4, which can degrade helodermin, can enhance host resistance to the toxicity of Gila monster venom. Mast cells and MCPT4 also can limit the toxicity associated with high concentrations of VIP and can reduce the morbidity and mortality induced by venoms from 2 species of scorpions. Our findings support the notion that mast cells can enhance innate defense by degradation of diverse animal toxins and that release of MCPT4, in addition to CPA3, can contribute to this mast cell function.

    2004-01-01

    Volatile substance abuse (VSA) is believed to be widespread. The Toxic Exposure Surveillance System (TESS) of the American Association of Poison Control Systems offers an opportunity to evaluate the epidemiology of volatile substance abuse using a data set that captures data from a large geographic area covering a wide-ranging group of socioeconomic strata, ethnic groups, and demographics. To utilize this potential we analyzed a data set of TESS for the 6-year period of 1996 through 2001 involving all cases of intentional inhalational abuse of nonpharmaceutical substances. Over the study period there was a mean annual decline of 9% of reported VSA with an overall decline of 37% from 1996 to 2001. Volatile substance abuse was reported primarily in children, with 6358 cases (54%) in children 13-19 yr and 1803 (15%) cases in children 6-12 yr. Fifty-two cases were reported in children air fresheners (6%), and formalin (5%). Three categories were responsible for the majority of deaths: gasoline (45%), air fresheners (26%), and propane/butane (11%). While there was a decline in reported cases, there was no decline in major outcomes or fatalities. Volatile substance abuse was reported in all 50 states, with case distribution similar to population distribution. However, seven states had > 2 times the expected rate based on their population; three western states, two midwestern states, and two Appalachian states. The role of urban vs. rural population may possibly explain the difference in numbers, with a greater incidence of VSA cases reported in states with large rural populations. The mean monthly occurrence rate was 162 VSA cases/month (S.D. +/- 10.85). There were 4 months that were > 2 standard deviations from the mean, with two peak months (May, 192/month and March, 187/month) and two trough months (December, 126/month and January, 137/month). This report presents a broad picture of VSA in the United States. Volatile substance abuse, as reported to U.S. poison centers

  3. National substance use patterns on Twitter.

    Full Text Available We examined openly shared substance-related tweets to estimate prevalent sentiment around substance use and identify popular substance use activities. Additionally, we investigated associations between substance-related tweets and business characteristics and demographics at the zip code level.A total of 79,848,992 tweets were collected from 48 states in the continental United States from April 2015-March 2016 through the Twitter API, of which 688,757 were identified as being related to substance use. We implemented a machine learning algorithm (maximum entropy text classifier to estimate sentiment score for each tweet. Zip code level summaries of substance use tweets were created and merged with the 2013 Zip Code Business Patterns and 2010 US Census Data.Quality control analyses with a random subset of tweets yielded excellent agreement rates between computer generated and manually generated labels: 97%, 88%, 86%, 75% for underage engagement in substance use, alcohol, drug, and smoking tweets, respectively. Overall, 34.1% of all substance-related tweets were classified as happy. Alcohol was the most frequently tweeted substance, followed by marijuana. Regression results suggested more convenience stores in a zip code were associated with higher percentages of tweets about alcohol. Larger zip code population size and higher percentages of African Americans and Hispanics were associated with fewer tweets about substance use and underage engagement. Zip code economic disadvantage was associated with fewer alcohol tweets but more drug tweets.The patterns in substance use mentions on Twitter differ by zip code economic and demographic characteristics. Online discussions have great potential to glorify and normalize risky behaviors. Health promotion and underage substance prevention efforts may include interactive social media campaigns to counter the social modeling of risky behaviors.

    In liver transplantation, adults with small stature have a greater susceptibility to waitlist mortality. This may explain the persistent waitlist mortality disparity that exists for women. We hypothesized that women who receive early offers of pediatric donor livers have improved waitlist survival, and that preferentially offering these organs to women mitigates this sex-based disparity. We analyzed donor liver offers from 2010 to 2014. Adult candidates who received a first offer that ranked within the first three match run positions from the donors' perspective were classified based on gender and whether they received a pediatric versus adult offer. We used competing risks regression to associate first offer type and waitlist mortality. 8,101 waitlist candidates received a first offer that was ranked within the first three match run positions: 5.6% (293/5,202) men and 6.2% (179/2,899) women received a pediatric donor liver as their first offer. In multivariable analyses, compared to adult-first men, adult-first women (sHR1.33, 95%CI 1.17-1.51, p offer had a lower risk of waitlist mortality compared to those who receive adult offers. Our data provides a simple approach to mitigating the increased waitlist mortality experienced by women by incorporating donor and recipient size, as variables, into organ allocation.

    During the first phases of adolescent development, young people have little self-efficacy and resistance against substance use. The aim of this study was to demonstrate the effectiveness of role-playing scenarios on the self-efficacy of students in resisting substance use. A pre test and post test study design was used with a single group. The study was carried out with 245 secondary school students. The scenario-based training, developed by the researchers, was presented by the school counselors once a week for 4 weeks. For this purpose, a booklet of scenarios was prepared for the teachers. The role-playing scenarios were intended to improve adolescents' abilities to say "no" to substance offers, to prevent them from becoming addicted to certain substances, and to call for help if needed. The data of the study were collected using the Personal Information Form and the Self-Efficacy for Adolescences Protecting Substance Abuse Scale . The obtained data were assessed using percentages, chi-square, t test, and F test in the SPSS software. Results showed that, after the training, the mean score in the Self-Efficacy for Adolescences Protecting Substance Abuse Scale increased significantly (103.20 ± 20.00) compared with before the training (92.11 ± 17.08) ( P < .05). Short-term outcomes of the class-based scenario training were observed to be effective in the development of students' self-efficacy to resist the temptations of substance use.

  8. [Acting out and psychoactive substances: alcohol, drugs, illicit substances].

    Science.gov (United States)

    Gillet, C; Polard, E; Mauduit, N; Allain, H

    2001-01-01

    In humans, some psychotropic agents (alcohol, drugs, illicit substances) have been suggested to play a role in the occurrence of major behavioural disorders, mainly due to the suppression of psychomotor inhibition. Behavioural disinhibition is a physiological mechanism which allows humans to behave appropriately according to a given environmental situation. The behavioural disinhibition induced by either therapeutic dosage or misuse involves the loss of restraint over certain types of social behaviour and may increase the risk of auto or hetero-aggression and acting out. The increased use of psychotropic agents in recent years and the occurrence of unwanted effects are worrying and must be detected and evaluated. The objective of the present study was to establish a causal relationship between psychoactive substance use and occurrence of major behavioural disorders, such as paradoxical rage reactions and suicidal behaviour, based on a literature analysis. It consisted of reviewing reports of drug-induced violent reactions in healthy volunteers and demonstrating, where possible, a cause-effect relationship. Patients with schizophrenia and psychopathic personalities were not included in our study since psychiatric comorbidity could influence behavioural responses. Psychotropic agents included drugs, licit and illicit substances already associated with violence in the past. Many reports used the "Go/No Go test" to evaluate the disinhibiting effect of psychotropic substances; this allows the "cognitive mapping" of drugs. The results suggest that only alcohol, antidepressants, benzodiazepines and cocaïne are related to aggressive behaviour. The best known precipitant of behavioural disinhibition is alcohol, which induces aggressive behaviour. However, there are large differences between individuals, and attentional mechanisms are now recognised as being important in mediating the effects of alcohol. Suicidal tendency as an adverse antidepressant reaction is rare

    The aim of the present research programme is to study the complexation behaviour of actinide ions with humic substances in natural aquifer systems and hence to quantify the effect of humic substances on the actinide migration. Aquatic humic substances commonly found in all groundwaters in different concentrations have a strong tendency towards complexation with actinide ions. This is one of the major geochemical reactions but hitherto least quantified. Therefore, the effect of humic substances on the actinide migration is poorly understood. In the present research programme the complexation of actinide ions with humic substances will be described thermodynamically. This description will be based on a model being as simple as possible to allow an easy introduction of the resulting constants into geochemical modelling of the actinide migration. (orig.)

  10. Alexithymia in Egyptian Substance Abusers.

    2001-03-01

    Alexithymia is thought of as a trait that predisposes to drug abuse. Moreover, it is suggested to be related to type of the substance abused, with the worst-case scenario including a worse prognosis as well as tendency to relapse or even not to seek treatment at all. To address this important subject in Egyptian patients, a sample of 200 Egyptian substance abusers was randomly selected from inpatients in the Institute of Psychiatry, Ain Shams University, Egypt. The study also included 200 group-matched controls. DSM-IV criteria were used for assessment of substance use disorders, and toxicologic urine analysis was used to confirm the substances of abuse. Toronto Alexithymia Scale (TAS)-Arabic version was used for assessment of alexithymia. It was found that alexithymia was significantly more prevalent in the substance use disorders group as compared to healthy controls. It was also found that among the substance use disorders group, alexithymics reported more polysubstance abuse, more opiate use (other than heroin IV), lower numbers of hospitalizations, lower numbers of reported relapses, and a lower tendency to relapse as a result of internal cues compared to patients without alexithymia. Statistically significant associations were also found between alexithymia and more benzodiazepine abuse and nonpersistence in treatment. The results suggest that alexithymia should be targeted in a treatment setting for substance use disorders.

    This study explored intentions to emigrate and substance use among youth (ages 14–24) from a central Mexico state with high emigration rates. Questionnaires were completed in 2007 by 702 students attending a probability sample of alternative secondary schools serving remote or poor communities. Linear and logistic regression analyses indicated that stronger intentions to emigrate predicted greater access to drugs, drug offers, and use of illicit drugs (marijuana, cocaine, inhalants), but not alcohol or cigarettes. Results are related to the healthy migrant theory and its applicability to youth with limited educational opportunities. The study’s limitations are noted. PMID:21955065

    Proline-rich oligopeptides (PROs) are a large family which comprises the bradykinin-potentiating peptides (BPPs). They inhibit the activity of the angiotensin I-converting enzyme (ACE) and have a typical pyroglutamyl (Pyr)/proline-rich structure at the N- and C-terminus, respectively. Furthermore, PROs decrease blood pressure in animals. In the present study, the isolation and biological characterization of a novel vasoactive BPP isolated from the skin secretion of the frog Brachycephalus ephippium is described. This new PRO, termed BPP-Brachy, has the primary structure WPPPKVSP and the amidated form termed BPP-BrachyNH2 inhibits efficiently ACE in rat serum. In silico molecular modeling and docking studies suggest that BPP-BrachyNH2 is capable of forming a hydrogen bond network as well as multiple van der Waals interactions with the rat ACE, which blocks the access of the substrate to the C-domain active site. Moreover, in rat thoracic aorta BPP-BrachyNH2 induces potent endothelium-dependent vasodilatation with similar magnitude as captopril. In DAF-FM DA-loaded aortic cross sections examined by confocal microscopy, BPP-BrachyNH2 was found to increase the release of nitric oxide (NO). Moreover, BPP-BrachyNH2 was devoid of toxicity in endothelial and smooth muscle cell cultures. In conclusion, the peptide BPP-BrachyNH2 has a novel sequence being the first BPP isolated from the skin secretion of the Brachycephalidae family. This opens for exploring amphibians as a source of new biomolecules. The BPP-BrachyNH2 is devoid of cytotoxicity and elicits endothelium-dependent vasodilatation mediated by NO. These findings open for the possibility of potential application of these peptides in the treatment of endothelial dysfunction and cardiovascular diseases.

  1. Intended or Unintended Doping? A Review of the Presence of Doping Substances in Dietary Supplements Used in Sports

    Directory of Open Access Journals (Sweden)

    José Miguel Martínez-Sanz

    2017-10-01

    Full Text Available Introduction: The use of dietary supplements is increasing among athletes, year after year. Related to the high rates of use, unintentional doping occurs. Unintentional doping refers to positive anti-doping tests due to the use of any supplement containing unlisted substances banned by anti-doping regulations and organizations, such as the World Anti-Doping Agency (WADA. The objective of this review is to summarize the presence of unlabeled doping substances in dietary supplements that are used in sports. Methodology: A review of substances/metabolites/markers banned by WADA in ergonutritional supplements was completed using PubMed. The inclusion criteria were studies published up until September 2017, which analyzed the content of substances, metabolites and markers banned by WADA. Results: 446 studies were identified, 23 of which fulfilled all the inclusion criteria. In most of the studies, the purpose was to identify doping substances in dietary supplements. Discussion: Substances prohibited by WADA were found in most of the supplements analyzed in this review. Some of them were prohormones and/or stimulants. With rates of contamination between 12 and 58%, non-intentional doping is a point to take into account before establishing a supplementation program. Athletes and coaches must be aware of the problems related to the use of any contaminated supplement and should pay special attention before choosing a supplement, informing themselves fully and confirming the guarantees offered by the supplement.

    Introduction: The use of dietary supplements is increasing among athletes, year after year. Related to the high rates of use, unintentional doping occurs. Unintentional doping refers to positive anti-doping tests due to the use of any supplement containing unlisted substances banned by anti-doping regulations and organizations, such as the World Anti-Doping Agency (WADA). The objective of this review is to summarize the presence of unlabeled doping substances in dietary supplements that are used in sports. Methodology: A review of substances/metabolites/markers banned by WADA in ergonutritional supplements was completed using PubMed. The inclusion criteria were studies published up until September 2017, which analyzed the content of substances, metabolites and markers banned by WADA. Results: 446 studies were identified, 23 of which fulfilled all the inclusion criteria. In most of the studies, the purpose was to identify doping substances in dietary supplements. Discussion: Substances prohibited by WADA were found in most of the supplements analyzed in this review. Some of them were prohormones and/or stimulants.

    Full Text Available This study tested the hypothesis that playing video games while using or feeling the effects of a substance—referred to herein as “concurrent use”—is related to substance use problems after controlling for substance use frequency, video gaming as an enthusiastic hobby, and demographic factors. Data were drawn from a nationally representative online survey of adult video gamers conducted by Knowledge Networks, valid n = 2,885. Problem video game playing behavior was operationalized using Tejeiro Salguero and Bersabé Morán’s 2002 problem video game play (PVP measure, and measures for substance use problems were taken from the National Survey of Drug Use and Health (NSDUH.

In all four models, concurrent use was directly associated with substance use problems, but not with PVP. Video gaming as an enthusiastic hobby was associated with substance use problems via two indirect paths: through PVP for all substances, and through concurrent use for caffeine, tobacco, and alcohol only. Results illustrate the potential for “drug interaction” between self-reinforcing behaviors and addictive substances, with implications for the development of problem use.

    2010-05-01

    To critically review the literature on topiramate in the treatment of substance-related disorders. A PubMed search of human studies published in English through January 2009 was conducted using the following search terms: topiramate and substance abuse, topiramate and substance dependence, topiramate and withdrawal, topiramate and alcohol, topiramate and nicotine, topiramate and cocaine, topiramate and opiates, and topiramate and benzodiazepines. 26 articles were identified and reviewed; these studies examined topiramate in disorders related to alcohol, nicotine, cocaine, methamphetamine, opioids, Ecstasy, and benzodiazepines. Study design, sample size, topiramate dose and duration, and study outcomes were reviewed. There is compelling evidence for the efficacy of topiramate in the treatment of alcohol dependence. Two trials show trends for topiramate's superiority over oral naltrexone in alcohol dependence, while 1 trial suggests topiramate is inferior to disulfiram. Despite suggestive animal models, evidence for topiramate in treating alcohol withdrawal in humans is slim. Studies of topiramate in nicotine dependence show mixed results. Human laboratory studies that used acute topiramate dosing show that topiramate actually enhances the pleasurable effects of both nicotine and methamphetamine. Evidence for topiramate in the treatment of cocaine dependence is promising, but limited by small sample size. The data on opioids, benzodiazepines, and Ecstasy are sparse. Topiramate is efficacious for the treatment of alcohol dependence, but side effects may limit widespread use. While topiramate's unique pharmacodynamic profile offers a promising theoretical rationale for use across multiple substance-related disorders, heterogeneity both across and within these disorders limits topiramate's broad applicability in treating substance-related disorders. Recommendations for future research include exploration of genetic variants for more targeted pharmacotherapies.

  6. Abortion Legalization and Adolescent Substance Use

    We assess whether in utero exposure to legalized abortion in the early 1970's affected individuals' propensities to use controlled substances as adolescents. We exploit the fact that some states legalized abortion before national legalization in 1973 to compare differences in substance use for adolescents across birth cohorts in different states. We find that persons exposed to early legalization were, on average, much less likely to use controlled substances. We also assess how substance use...

    A variety of special regulations exist in Costa Rica for registration and transport of hazardous substances; these set the requirements for entry into the country and the security of transport units. However, the regulations mentioned no specific rules for storing hazardous substances. Tax deposits have been the initial place where are stored the substances that enter the country.The creation of basic rules that would be regulating the storage of hazardous substances has taken place through the analysis of regulations and national and international laws governing hazardous substances. The regulatory domain that currently exists will be established with a field research in fiscal deposits in the metropolitan area. The storage and security measures that have been used by the personnel handling the substances will be identified to be putting the reality with that the hazardous substances have been handled in tax deposits. A rule base for the storage of hazardous substances in tax deposits can be made, protecting the safety of the environment in which are manipulated and avoiding a possible accident causing a mess around. The rule will have the characteristics of the storage warehouses hazardous substances, such as safety standards, labeling standards, infrastructure features, common storage and transitional measures that must possess and meet all bonded warehouses to store hazardous substances.

    2013-06-01

    Adolescents who experience homelessness are at higher risk for abusing substances, and for being exposed to substance-using peers. The current study used a longitudinal design to track substance abuse, affiliation with substance-using peers, and episodes of homelessness among a sample of 223 adolescents who were housed at the baseline data collection and 148 adolescents who were housed at baseline. Participants were interviewed at six waves over 6.5 years, covering an age range from 13 to 25. Many participants experienced a recurrence of homelessness during follow-up, with 64.6 % of the baseline homeless group and 22.6 % of the baseline housed group reporting an additional episode of homelessness. Both alcohol abuse and other drug abuse symptoms showed an increase in adolescence followed by slowing in early adulthood. Recent homelessness and friend alcohol use predicted alcohol abuse symptoms, and the strength of the influence of friend use decreased over time. Recent homelessness and friend drug use predicted other drug abuse symptoms. Duration of the initial episode of adolescent homelessness showed no influence on substance abuse over time, or the effects of other predictors, highlighting the importance of conceptualizing the experience of homelessness as a recent stressor rather than an enduring personal characteristic.

    2014-05-01

    Past research showed a relationship between substance abuse and aggression and past trauma and aggression. The nature of the relationships between substance use, trauma, and aggression is inconclusive. The current research hypothesized greater aggression among those with a history of substance abuse and trauma compared with those without such a history and an additive relationship between substance abuse and trauma on aggression. Participants were 615 individuals in a substance abuse treatment program for individuals under criminal justice supervision. Data were collected from face-to-face interviews and self-report measures. Univariate and multivariate analyses assessed the relationships among substance use, trauma, and aggression. Participants with a history of trauma and regular substance use reported the highest rates of homicidal ideation, problem behaviors, and person offenses. Participants in this group also reported greater desire for help managing their stress and tension, dealing with problems in their intimate relationships, developing healthier relationships in general, and learning prosocial approaches to express their feelings. Substance abusing participants who experienced trauma reported more externalizing behaviors and a greater desire for coping- and social-skills training than participants who abused substances but did not report a history of trauma. This suggests that participants in substance abuse treatment programs may have improved outcomes with the addition of components to address these issues.

    2015-01-01

    Background Following completion of substance use treatment, it is crucial for patients to continue to utilize skills learned in treatment for optimal treatment outcomes. Mobile applications (apps) on smartphones offer a unique platform to promote utilization of evidence-based skills following completion of substance use treatment. Despite the promise of mobile apps and smartphones for treatment delivery, it remains unknown whether patients in substance use treatment in the United States have access to smartphones and utilize mobile apps on smartphones. The present study sought to determine smartphone utilization among individuals enrolled in one residential substance use treatment center in the U.S catering specifically to low-income adults. Methods Participants included 251 individuals at a residential substance use treatment center in Washington DC admitted to the center between March, 2014 and January, 2015. During the intake process, participants completed interviewer-administered demographics and psychiatric questionnaires as well as a self-report of technology utilization. Results Results indicated that the majority of patients in this residential substance use treatment center owned mobile phones prior to treatment entry (86.9%) and expected to own mobile phones after leaving treatment (92.6%). Moreover, the majority of these phones were (68.5%) or will be smartphones (72.4%) on which patients reported utilizing mobile applications (Prior to treatment: 61.3%; Post treatment: 64.3%) and accessing the internet (Prior to treatment: 61.3%; Post treatment: 65.9%). Conclusions Mobile phone and smartphone ownership among this sample were comparable to ownership among U.S. adults broadly. Findings suggest that smartphones and mobile apps may hold clinical utility for fostering continued use of treatment skills following substance use treatment completion. PMID:26231698

    A well functioning immune system is essential in maintaining integrity of the organism, and malfunction may have severe health consequences. Environmental substances may pose direct toxicity to components of the immune system, often leading to immunosuppression and resulting reduced resistance to infections and tumors. Alternatively, such substances may be recognized by the immune system in a specific fashion, which may result in allergy and autoimmunity. A proper risk assessment of environmental substances in terms of immunotoxicity is necessary. In this manuscript, I reviewed recent three topics about immunotoxicity: (1) IPCS/WHO Guidance for immunotoxicity risk assessment for chemicals, (2) Intestinal immunotoxicity, and (3) Epicutaneous sensitization of food proteins.

    Crime rates are high in substance-using populations; therefore, investigation of factors associated with crime in these populations is highly relevant. We describe crime prevalence and associations between crime, pattern of substance use and psychosocial factors, such as self-control and social network. This is a cross-sectional study including substance users (n = 549; mean age 34 years; 27% women) entering treatment at 21 treatment centres across Norway (December 2012 to April 2015). Data on demographics, substance use, psychosocial variables and crime in the 6 months prior to treatment were obtained through interviews. Adjusted odds ratios (aOR) with 95% confidence intervals (CI) were estimated through logistic regression. Sixty-four percent of participants had committed crime in the 6 months prior to treatment. Of these, 93% committed income-generating crime. Several factors were associated with increased likelihood of having committed crime: use of stimulants (aOR = 1.82, 95% CI 1.04-3.17), use of a higher number of different substances (aOR = 1.16, 95% CI 1.04-1.31) and spending most of their time with family or friends using addictive substances (aOR = 2.38, 95% CI 1.10-5.16 and aOR = 2.22, 95% CI 1.32-3.73). Protective factors associated with decreased likelihood of committing crime were being older (aOR = 0.95, 95% CI 0.92-0.97) and having higher self-control (aOR = 0.94, 95% CI 0.91-0.97). Stimulant use, higher number of different substances used, lower self-control, primarily a substance-using social network and being younger were associated with crime in this substance-using population. Treatment clinics should consider these risk factors for crime, and suitable interventions should be implemented and evaluated. [Skjaervø I, Skurtveit S, Clausen T, Bukten A.

    Both music preferences and the substance use behavior of peers are important elements in explaining adolescent substance use. The extent to which music preference and peer use overlap in explaining adolescent substance use remains to be determined. A nationally representative sample of 7324 Dutch school-going adolescents (aged 12-16) provided data on music preferences, substance use behaviors and perceived number of peers using substances. Factor analyses showed that preferences for eight music genres factored into four styles: Pop (chart music, Dutch pop), Adult (classical music, jazz), Urban (rap/hiphop, soul/R&B) and Hard (punk/hardcore, techno/hardhouse); substance use was indicated by smoking, drinking, and cannabis use. Structural equation modeling revealed that the relationship between music preference and substance use was either wholly or partially mediated by perceived peer use. Music can model substance use and fans of different types of music may select friends with use patterns that reinforce their own substance use inclinations.

    2005-03-01

    Substance abuse is among one of the major problems plaguing our society. It has come to the attention of several healthcare professionals that a communication gap exists between themselves and substance abusers. Most of the time the substance abusers are only familiar with the slang terms of abused substances, a terminology that medical professionals are usually unaware of. This paper is an attempt to close that communication gap, allowing health care professionals to understand the slang terminology that their patients use, thus enabling them to make appropriate treatment decisions. In addition, the article presents some key features (including active ingredient, pharmacological classification, medical use, abuse form, usage method, combinations used, effects sought, long-term possible effects, and detectability in urine) of the most commonly abused substances.

    Functional and mental health impairments that adults with attention-deficit/hyperactivity disorder (ADHD) experience may be exacerbated by regular substance use and co-morbidity with substance use disorders (SUD). This may be especially true during young adulthood, which represents a critical stage of life associated with increased substance use and associated problems. However, previous studies investigating the association between ADHD and substance use and SUD have demonstrated inconsistent results, probably due to methodological limitations (e.g., small and non-representative samples). Thus, the relationship of ADHD with substance use and related disorders remains unclear. The aim of the present study was to examine the association between ADHD and both the use of licit and illicit substances and the presence of SUD in a large, representative sample of young men. The sample included 5677 Swiss men (mean age 20 ± 1.23 years) who participated in the Cohort Study on Substance Use Risk Factors (C-SURF). ADHD was assessed using the adult ADHD Self Report Screener (ASRS). The association between ADHD and substance use and SUD was assessed for alcohol, nicotine, cannabis and other illicit drugs, while controlling for socio-demographic variables and co-morbid psychiatric disorders (i.e., major depression (MD) and anti-social personality disorder (ASPD)). Men with ADHD were more likely to report having used nicotine, cannabis and other illicit drugs at some time in their life, but not alcohol. ADHD was positively associated with early initiation of alcohol, nicotine and cannabis use, the risky use of these substances, and the presence of alcohol use disorders, and nicotine and cannabis dependence. Additionally, our analyses revealed that these patterns are also highly associated with ASPD. After adjusting for this disorder, the association between ADHD and licit and illicit substance use and the presence of SUDs was reduced, but remained significant. Our findings

  2. Substance use during pregnancy: time for policy to catch up with research

    2004-04-01

    Full Text Available Abstract The phenomenon of substance abuse during pregnancy has fostered much controversy, specifically regarding treatment vs. punishment. Should the pregnant mother who engages in substance abuse be viewed as a criminal or as someone suffering from an illness requiring appropriate treatment? As it happens, there is a noticeably wide range of responses to this matter in the various states of the United States, ranging from a strictly criminal perspective to one that does emphasize the importance of the mother's treatment. This diversity of dramatically different responses illustrates the failure to establish a uniform policy for the management of this phenomenon. Just as there is lack of consensus among those who favor punishment, the same lack of consensus characterizes those states espousing treatment. Several general policy recommendations are offered here addressing the critical issues. It is hoped that by focusing on these fundamental issues and ultimately detailing statistics, policymakers throughout the United States will consider the course of action that views both pregnant mother and fetus/child as humanely as possible.

    Despite the high prevalence and known morbidity and mortality caused by cigarette smoking, 60% to 70% of substance abuse treatment programs lack smoking cessation counseling or fail to offer pharmacotherapy for smoking cessation, including those programs designed to meet the needs of drug-dependent pregnant patients. Previous studies of staff knowledge, attitudes, and practices (S-KAP) at general substance abuse/HIV treatment programs have suggested that staff may contribute to the deficiency in smoking cessation treatment in these settings. It is not known whether similar deficiencies exist at perinatal substance abuse treatment programs. This study compared cigarette S-KAP in perinatal substance abuse (n = 41) and general substance abuse/HIV treatment (Veterans Affairs [VA] medical center, hospital-, and community-based) workforce samples (n = 335). Significant differences were seen between the 2 groups on all measures, but perinatal staff compared favorably to general staff only on measures of barriers to smoking cessation services. Perinatal staff compared unfavorably on all other measures: knowledge, beliefs/attitudes, self-efficacy, and smoking cessation practices. Pair-wise comparisons of knowledge and beliefs/attitudes revealed a significant difference between perinatal and VA staff; of self-efficacy, between perinatal and staff at all other settings; and of smoking cessation practices, between perinatal and VA and community-based staff. These results-showing deficiencies of perinatal staff on most S-KAP measures-are concerning and suggest that identifying gaps in and improving S-KAP in perinatal substance abuse programs is urgently needed, for which the VA may provide an efficacious model.

    Full Text Available Background: Illicit substance use is a serious social problem faced by adolescents worldwide, including adolescents in Aceh and has many negative consequences. In addition, illicit substance use does not fit with the values of Islamic teaching, and is strictly prohibited in Islam. Purpose: The aims of this paper are to determine the prevalence of illicit substance use, the stages of substance use, and types of substance used among Muslim students in senior high schools in Aceh, Indonesia. Method: Four hundred and twenty six students who met the inclusion criteria were recruited from four senior high schools in Banda Aceh by using simple random sampling, and of these, 290 returned a completed questionnaire. A self reported questionnaire was used to collect data. Result: The mean age of the subjects was 15.9 years old and the majority of them were female (68.6%. The study found that the prevalence of substance use was 2.4%with a higher number of females than males who had used illicit substances. The common substances that were used by the students were marijuana and dextromethorphon, as well as intentionally inhaled substances. Lastly, out of the students who had used illegal substances the majority was in the regular use stage (1.4%. Conclusion: This study found that substance use among Muslim students in Aceh exists, although prevalence was low. Thus, several preventive programs may be needed in Aceh not only for Muslims students who have used substances but also for students who have not use illegal substances. Keywords: Adolescents, Substance use, Muslim students, Indonesia.

    This study determines the substance use and abuse patterns among patients with comorbid substance-related disorder (SRD) and dysthymia in SRD-dysthymia as compared with patients with SRD only. Differences in use and abuse patterns could be useful for (a) understanding motivations for use, such as self-treatment, and (b) assisting clinicians to identify cases of dysthymia among SRD patients. Retrospective and current data were obtained regarding history of substance use and current SRD diagnoses. Two university medical centers with alcohol-drug programs located within departments of psychiatry were the settings. A total of 642 patients was assessed. of whom 39 had SRD-dysthymia and 308 had SRD only. Data on past usc were collected by a research associate using a questionnaire. Current SRD and dysthymia diagnoses were made by psychiatrists specializing in addiction. The patients with SRD-dysthymia and SRD only did not differ with regard to use of alcohol, tobacco, and benzodiazepines. The patients with SRD-dysthymia started caffeine use at an earlier age, had shorter "use careers" of cocaine, amphetamines, and opiates, and had fewer days of cocaine and cannabis use in the last year. They also had a lower rate of cannabis abuse/dependence. This study indicated that patients with dysthymia and SRD have exposure to most substances of abuse that is comparable to patients with SRD only. However, they selectively use certain substances less often than patients with SRD only. Early use of caffeine may reflect self-treatment for depressive symptoms among patients with SRD-dysthymia.

  6. Detection of diffusible substances

    1976-12-01

    The different steps of a radioautographic technique for the detection of diffusible substances are described. Using this radioautographic method, the topographic distribution of estradiol-concentrating neurons was studied in the nervous system and pituitary of the ovariectomized mouse and guinea-pig. A relatively good morphological preservation of structures can be ascertained on sections from unfixed, unembedded tissues prepared at low temperatures and kept-under relatively low humidity. The translocation or extraction of diffusible substances is avoided by directly mounting of frozen sections on dried photographic emulsion. Since no solvent is used, this technique excludes the major sources of diffusion artifacts and permits to be in favourable conditions for the localization of diffusible substances.

    Full Text Available When we compare the categories about alcohol, and substance-related disorders in DSM-IV and DSM-5, the new category, named addictive disorders is the most striking change. Only gambling disorder have been identified currently in this category. This may be the most remarkable change among the changes in the DSM-5. Because the expansion of the existing diagnostic criteria may cause the assessment of and lsquo;normal behavior' as a disorder. Additionally, withdrawal of caffeine and cannabis are defined in the DSM-5. Disorders collected under the title of substance-related disorders in the DSM-IV were collected under the name of substance-related and addictive disorders in the DSM-5. Specific criterias for substance abuse and substance addiction have been combined into the name of "substance use disorders". In substance abuse, "experienced legal problems" criteria was removed and "a strong desire or urge or craving for substance use" criteria has been introduced. Henceforth, substance abuse is defined as a mild form of substance use disorders in the DSM-5. A change in the prevalence of substance use disorders should be investigated by the new researches.

    Rosen, Daniel; Engel, Rafael J; Hunsaker, Amanda E; Engel, Yael; Detlefsen, Ellen Gay; Reynolds, Charles F

    2013-01-01

    This article examines the extent to which studies of alcohol abuse, illicit drug use, and prescription drug abuse among older adults appear in the leading gerontological and substance abuse journals. The authors reviewed articles published in the 10 social science gerontological journals and the 10 social science substance abuse journals with the highest 5-year impact factors in PubMed from 2000 to 2010. Articles were selected that presented original research on alcohol, substance, or prescription abuse with older adults aged 50 and older; and were identified through aging and substance abuse-related Medical Subject Headings and word searches of titles and abstracts (N = 634). Full text of each article was reviewed by the authors, and consensus determined inclusion in the final sample. Of the 19,953 articles published respectively in the top 10 gerontological and substance abuse journals, 181 articles met the inclusion criteria of reporting findings related to substance use disorders among older adults. Specifically, 0.9% (102 of 11,700) of articles from the top 10 gerontology journals and 1.0% (79 of 8,253) of articles from the top 10 substance abuse journals met the criteria. Most published articles addressed alcohol misuse/abuse or polysubstance abuse with few articles addressing illicit drug use or the misuse of prescription medications. Less than 1% of articles published in the 10 gerontology journals and the 10 substance abuse journals with the highest 5-year impact scores addressed substance abuse in older adults. Practitioners treating health and/or mental health problems are at a disadvantage in accurately identifying and treating these conditions in older adult populations without a proper understanding of the role of comorbid substance use disorders.

    2015-07-01

    Transgender people have elevated substance use prevalence compared with the U.S. general population, however no studies have comprehensively examined the relationship of psychosocial risk factors to substance use and substance use disorder (SUD) treatment among both male-to-female (MTF) and female-to-male (FTM) transgender adults. Secondary data analysis of a 2013 community-based survey of transgender adults in Massachusetts (N=452) was conducted. Adjusted multivariable logistic regression models were fit to examine the relationship of four risk factor domains with SUD treatment history and recent substance use: (1) demographics; (2) gender-related characteristics; (3) mental health; (4) socio-structural factors. Adjusted Odds Ratios (aOR) and 95% Confidence Intervals (95% CI) were estimated. Ten percent of the sample reported lifetime SUD treatment. Factors associated with significant increase in odds of lifetime SUD treatment alongside recent substance use (all pdiscrimination (aOR=1.90; 95% CI=1.22-2.95), unstable housing (aOR=1.80; 95% CI=1.21-2.67), and sex work (aOR=2.48; 95% CI=1.24-4.95). Substance use and SUD treatment among transgender adults are associated with demographic, gender-related, mental health, and socio-structural risk factors. Studies are warranted that identify SUD treatment barriers, and integrate SUD treatment with psychosocial and structural interventions for a diverse spectrum of transgender adults.

  17. [Dual diagnosis psychosis and substance use disorders: theoretical foundations and treatment].

    Gouzoulis-Mayfrank, Euphrosyne

    2008-07-01

    Dual Diagnosis (DD) patients with psychosis and substance use disorders (SUD) represent a large core group among patients with schizophrenia. Cannabis use disorders are most prevalent among DD patients, particularly in adolescent and young adult populations. There are different models to explain the high rates of comorbidity between psychosis and SUD. Currently, evidence is best for the model of cannabis use being a component cause of psychosis in individuals who are highly vulnerable to psychosis. There is also some evidence for the model of common vulnerability factors for psychosis and SUD. DD patients are difficult to treat as they comply poorly, their long-term outcomes are unfavourable and they suffer frequent psychotic relapses and hospitalisations. Successful treatment models integrate traditional psychiatric therapy for psychosis and therapy for addiction in one setting, modifying and adjusting the two components to the special needs of the DD patients. Integrated programmes focus mostly on long-term outpatient treatment and offer pharmacotherapy, motivational enhancement, psychoeducation, cognitive-behavioural therapy and family interventions. Current clinical research demonstrates that integrated treatment programmes can achieve significant improvements with regard to the social adjustment of, as well as decreased substance use by DD patients.

    Cigarette smoking is common among patients in substance abuse treatment. Tobacco control programs have advocated for integrated tobacco dependence treatment into behavioral healthcare, including within substance abuse treatment facilities (SATFs) to reduce the public health burden of tobacco use. This study used data from seven waves (2006 to 2012) of the National Survey of Substance Abuse Treatment Services (n=94,145) to examine state and annual changes in the provision of smoking cessation services within US SATFs and whether changes over time could be explained by facility-level (private vs public ownership, receipt of earmarks, facility admissions, acceptance of government insurance) and state-level factors (cigarette tax per pack, smoke free policies, and percent of CDC recommended tobacco prevention spending). Results showed that the prevalence of SATFs offering smoking cessation services increased over time, from 13% to 65%. The amount of tax per cigarette pack, accepting government insurance, government (vs private) ownership, facility admissions, and CDC recommended tobacco prevention spending (per state) were the strongest correlates of the provision of smoking cessation programs in SATFs. Facilities that received earmarks were less likely to provide cessation services. Adult smoking prevalence and state-level smoke free policies were not significant correlates of the provision of smoking cessation services over time. Policies aimed at increasing the distribution of tax revenues to cessation services in SATFs may offset tobacco-related burden among those with substance abuse problems. Copyright © 2017.

    Full Text Available Background and Objective: The previous research has demonstrated that addiction treatment services for women need to be based on knowledge of female psychological needs. Therefore, the aim of current study is to compare body image, quality of sleep and marital satisfaction among substance abuser and non-substance abuser women.Materials and Methods: This study is a descriptive comparative research. 200 women including 100 substance abuser women and 100 non-substance abuser women were chosen through convenience method in Arak in 2015. The measuring instruments were Fisher body image scale (1970, Pittsburgh Sleep Quality Index (1989 and Enrich Marital Satisfaction Scale (1989. Data was analyzed utilizing t independent.Results: The results showed that there is the significant difference between marital satisfaction (P=0.001 and quality of sleep (P=0.001 among substance abuser and non-substance abuser women. Additionally, the significant difference was not observed between body image (P= 0.31 among these two groups.Conclusion: These findings emphasized that substance use decreases the quality of sleep and marital satisfaction in women. Hence, it should be considered these factors in process of therapeutic intervention in substance abuser women.

    We developed a kidney offer acceptance decision tool to predict the probability of graft survival and patient survival for first-time kidney-alone candidates after an offer is accepted or declined, and we characterized the effect of restricting the donor pool with a maximum acceptable kidney donor profile index (KDPI). For accepted offers, Cox proportional hazards models estimated these probabilities using transplanted kidneys. For declined offers, these probabilities were estimated by considering the experience of similar candidates who declined offers and the probability that declining would lead to these outcomes. We randomly selected 5000 declined offers and estimated these probabilities 3 years post-offer had the offers been accepted or declined. Predicted outcomes for declined offers were well calibrated (offers been accepted, the probabilities of graft survival and patient survival were typically higher. However, these advantages attenuated or disappeared with higher KDPI, candidate priority, and local donor supply. Donor pool restrictions were associated with worse 3-year outcomes, especially for candidates with high allocation priority. The kidney offer acceptance decision tool could inform offer acceptance by characterizing the potential risk-benefit trade-off associated with accepting or declining an offer. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

  7. Intracerebroventricular Infusion of Vasoactive Intestinal Peptide (VIP Rescues the Luteinizing Hormone Surge in Middle-Aged Female Rats

    Directory of Open Access Journals (Sweden)

    Yan eSun

    2012-02-01

    Full Text Available Reproductive aging is characterized by delayed and attenuated luteinizing hormone (LH surges apparent in middle-aged rats. The suprachiasmatic nucleus (SCN contains the circadian clock that is responsible for the timing of diverse neuroendocrine rhythms. Electrophysiological studies suggest vasoactive intestinal peptide (VIP originating from the SCN excites gonadotropin-releasing hormone (GnRH neurons and affects daily patterns of GnRH-LH release. Age-related LH surge dysfunction correlates with reduced VIP mRNA expression in the SCN and fewer GnRH neurons with VIP contacts expressing c-fos, a marker of neuronal activation, on the day of the LH surge. To determine if age-related LH surge dysfunction reflects reduced VIP availability or altered VIP responsiveness under estradiol positive feedback conditions, we assessed the effect of intracerebroventricular (icv VIP infusion on c-fos expression in GnRH neurons and on LH release in ovariohysterectomized, hormone-primed young and middle-aged rats. Icv infusion of VIP between 1300 and 1600 h significantly advanced the time of peak LH release, increased total and peak LH release, and increased the number of GnRH neurons expressing c-fos on the day of the LH surge in middle-aged rats. Surprisingly, icv infusion of VIP in young females significantly reduced the number of GnRH neurons expressing c-fos and delayed and reduced the LH surge. These observations suggest that a critical balance of VIP signaling is required to activate GnRH neurons for an appropriately timed and robust LH surge in young and middle-aged females. Age-related LH surge changes may, in part, result from decreased availability and reduced VIP-mediated neurotransmission under estradiol positive feedback conditions.

    It is well established that craving increases following exposure to substance-related 'cues', but the role of life-styles or substance use habits that are unique to each person remains poorly understood. This study examines the association of substance-specific and personal cues with craving and substance use in daily life. Ecological momentary assessment was used during a 2-week period. Data were collected in a French out-patient addiction treatment centre. A total of 132 out-patients beginning treatment for alcohol, tobacco, cannabis or opiate addiction were included. Using mobile technologies, participants were questioned four times per day relative to craving, substance use and exposure to either substance-specific cues (e.g. seeing a syringe) or personal cues unique to that individual (e.g. seeing the specific person with whom the substance is used). Craving intensity was associated with the number of concurrently assessed substance-specific cues (t = 4.418, P addictive substances, and the duration of this association may persist longer than for more general substance-specific cues. Mobile technologies provide new opportunities for understanding these person-specific risk factors and for providing individually tailored interventions. © 2015 Society for the Study of Addiction.

    2013-05-01

    Maternal substance abuse is a critical problem, and adolescent mothers appear to be at high risk for such behaviors. We review studies on postpartum adolescent substance use to explore the extent of this problem and avenues for new research. Authors screened 1,300 studies, identifying 12 articles on substance use among postpartum adolescent mothers for this review. Adolescent mothers reported greater substance use before pregnancy compared to other adolescent females. Although some adolescents continued substance use during pregnancy, most stopped using only to resume within six months after birth. Comparisons of use to national samples of nulliparous adolescent females showed a higher prevalence of substance use in this population. Substances used often varied by race/ethnicity, with white mothers more likely to smoke cigarettes and use marijuana, and Black mothers more likely than whites to drink and use drugs. Of all identified studies, only one focused on Hispanics. Beliefs about drug use grew less negative as girls transitioned from pregnancy to parenthood. As they transitioned to adulthood, substance use remained prevalent and stable. Psychological distress and low self-esteem appeared to influence continued use. Friends' cigarette smoking predicted early initiation of and persistent smoking, while increased education predicted quitting. Early initiation of substances often predicted problem behaviors. Adolescent mothers are a vulnerable population, implicating use of problem behavior theory or the self-medication hypothesis in future research. Multiple avenues for new studies are needed to help identify effective treatment and intervention for this understudied population.

    Electronic cigarettes as possibly healthier alternative to conventional cigarettes are gaining popularity worldwide, although they are still hazardous to human health. Partly it is caused by unregulated advertising and online sales. Unfortunately it is more and more popular for youth to try electronic cigarettes. The aim of the study was to assess the marketing claims used by Polish websites offering electronic cigarettes. A search using Google search engine was performed in July 2015 for two keywords: e-papierosy [e-cigarettes] and elektroniczne papierosy [electronic cigarettes]. First 150 websites (15 pages) were listed. After initial review 86 pages met all inclusion criteria and were included in the study. Pages were searched for presence of 13 selected marketing claims as well as age-related warning and any social websites connections. Age-related warning was present on only 33.72% (n=29) websites. Two thirds has its own Facebook fan-page with average 1922.09 ± 3634.86 likes. Articles about health are available on 10.46% (n=9) websites, 53.49% (n=46) states that e-cigarettes are healthier than conventional ones, 39.53% (n=34) emphasized that during usage of e-cigarettes no tarry substances are produced. Two pages had special article in which conventional and electronic cigarettes were compared. Almost half (44.19%) remarked that e-cigarettes are cheaper in usage than conventional, one third pointed out the simplicity of usage. 32.56% advertised e-cigarettes as aid in quitting smoking. One fourth stated that e-cigarettes are harmless for surroundings. 33.72% marketed them as a way of bypassing public smoking act. 56.98% remarked the variety of liquid tastes offered. Electronic cigarettes and their rising popularity create another new possible threat for public health as the widely available information emphasize safety of e-cigarettes usage and as their availability and usage is not limited or restricted by law. electronic cigarettes, e-cigarettes, internet

    Findings of pharmacological studies revealed that vasoactive intestinal peptide (VIP) plays a modulatory role in learning and memory. A role of the peptide in the neurobiological mechanisms of affective disorders was also suggested. The objectives are to study the involvement of VIP in learning and memory processes after unilateral and bilateral local application into hippocampal CA1 area in rats with a model of depression (bilateral olfactory bulbectomy--OBX) and to test whether VIP receptors could affect cognition. VIP (50 ng) and combination (VIP(6-28) 10 ng + VIP 50 ng) microinjected bilaterally or into the right CA1 area improved the learning and memory of OBX rats in shuttle-box and step-through behavioral tests as compared to the saline-treated OBX controls. Left-side VIP microinjections did not affect the number of avoidances (shuttle box) and learning criteria (step through) as compared to the left-side saline-treated OBX controls. The administration of the combination into left CA1 influenced positively the performance in the step-through task. VIP antagonist (VIP(6-28), 10 ng) did not affect learning and memory of OBX rats. These findings suggest asymmetric effect of VIP on cognitive processes in hippocampus of rats with OBX model of depression. Our results point to a lateralized modulatory effect of VIP injected in the hippocampal CA1 area on the avoidance deficits in OBX rats. The right CA1 area was predominantly involved in the positive effect of VIP on learning and memory. A possible role of the PAC1 receptors is suggested.

    The Vasoactive Intestinal Peptide (VIP) is a 28-amino acid polypeptide with a great numbers of receptors in tumoral cells, including adenocarcinomas and pancreatic and colon carcinomas. The VIP molecule contains two tyrosine residues, in positions 10 and 22, that are theoretically equally susceptible to iodination, The VIP was labeled with 131-iodine by direct method using Iodogen as oxidant agent: 15.03 mmol VIP + 0.10 nmol KI + [{sup 131} I]NaI + 13.9 mmol Iodogen; the final volume was adjust to 100 {mu}L using 0.2 M phosphate buffer, pH 7.5 and the reaction proceed with stirring for 30 minutes at room temperature. The radiochemical purity was determined by electrophoresis (Whatman 1MM paper; 0.05 M barbital buffer; pH 8.6; 150 V; 40 minutes) that indicates low percent of free 131-iodine. The high performance liquid chromatography (HPLC) system using RPC{sup 18}, 10 {mu}m, 4 x 250mm column, was able to separate the different radiochemical species, only when an isocratic mixture of acetonitrile: 0.1% trifluoroacetic acid (27:73) was used, with 0.5 mL/min. flux.

    To systematically review the literature on contraceptive use by women with opioid and other substance use disorders in order to estimate overall contraceptive use and to examine method choice given the alarmingly high rate of unintended pregnancy in this population. Pubmed (1948-2014) and PsycINFO (1806-2014) databases were searched for peer-reviewed journal articles using a systematic search strategy. Only articles published in English and reporting contraceptive use within samples of women with opioid and other substance use disorders were eligible for inclusion. Out of 580 abstracts reviewed, 105 articles were given a full-text review, and 24 studies met the inclusion criteria. The majority (51%) of women in these studies reported using opioids, with much smaller percentages reporting alcohol and cocaine use. Across studies, contraceptive prevalence ranged widely, from 6%-77%, with a median of 55%. Results from a small subset of studies (N=6) suggest that women with opioid and other substance use disorders used contraception less often than non-drug-using comparison populations (56% vs. 81%, respectively). Regarding method choice, condoms were the most prevalent method, accounting for a median of 62% of contraceptives used, while use of more effective methods, especially implants and intrauterine devices (IUDs), was far less prevalent 8%. Women with opioid and other substance use disorders have an unmet need for contraception, especially for the most effective methods. Offering contraception services in conjunction with substance use treatment and promoting use of more effective methods could help meet this need and reduce unintended pregnancy in this population.

    Objective: There has been an increase in the use of social network analysis in studies of peer socialization effects on adolescent substance use. Some researchers argue that social network analyses provide more accurate measures of peer substance use, that the alternate strategy of assessing perceptions of friends’ drug use is biased, and that perceptions of peer use and actual peer use represent different constructs. However, there has been little research directly comparing the two effects, and little is known about the extent to which the measures differ in the magnitude of their influence on adolescent substance use, as well as how these two effects may be redundant or separate constructs. Method: Using Waves I and II of the National Longitudinal Study of Adolescent Health (Add Health) saturated subsample, we directly compared effects of perception of friends’ use (PFU) and actual friends’ use (AFU) on alcohol, cigarette, and marijuana initiation and persistence of use 1 year later. We also examined potential moderating effects of friendship quality and individual use on the relationship between perceived and actual friends’ substance use and outcomes. Results: Results indicated that, overall, PFU effects were larger than AFU effects; however, these effects did not significantly differ in magnitude for most models. In addition, interaction effects differed for different substances and usage outcomes, indicating the meaning of PFU and AFU constructs (and thus, different types of peer socialization) may change based on substance and type of use. Conclusions: These results highlight the multifaceted nature of peer influence on substance use and the importance of assessing multiple aspects of peer socialization while accounting for distinct contexts related to specific substances and use outcomes.

    Dialectical behavior therapy (DBT) identifies emotion dysregulation as central to the dangerous impulsivity of borderline personality disorder (BPD) including substance use disorders, and DBT targets improved emotion regulation as a primary mechanism of change. However, improved emotion regulation with DBT and associations between such improvement and behavioral outcomes such as substance use has not been previously reported. Thus, the goal of this study was to assess for improvement in emotion regulation and to examine the relationship between improvements in the emotion regulation and substance use problems following DBT treatment. Emotion regulation as assessed by the Difficulties in Emotion Regulation Scale, depressed mood as assessed by the Beck Depression Inventory, and their associations with substance use frequency were investigated in 27 women with substance dependence and BPD receiving 20 weeks of DBT in an academic community outpatient substance abuse treatment program. Results indicated improved emotion regulation, improved mood, and decreased substance use frequency. Further, emotion regulation improvement, but not improved mood, explained the variance of decreased substance use frequency. This is the first study to demonstrate improved emotion regulation in BPD patients treated with DBT and to show that improved emotion regulation can account for increased behavioral control in BPD patients. SIGNIFICANCE AND FUTURE RESEARCH: Emotion regulation assessment is recommended for future studies to further clarify the etiology and maintenance of disorders associated with emotional dysregulation such as BPD and substance dependence and to further explore emotion regulation as a potential mechanism of change for clinical interventions.

    Psychosocial Characteristics of Adolescent Girls with Posttraumatic Stress Disorders and Substance Use Disorders Already in adolescence posttraumatic stress disorder (PTSD) and substance use disorders (SUD) often occur comorbid. SUD is usually in the focus of treatment and underlying PTSD is not always recognized. To date there is no explicit offer for the simultaneous treatment of both clinical pictures in adolescence. In the present study we tested whether the group intervention Seeking Safety, that is implemented successfully in adulthood, would also be interesting for the youth clientele. In addition we analyzed the characteristics of a target group of girls and young women between 14 and 21 years, that could be reached for such a program in a German city. In the present study we conducted 39 complete interviews that enable an estimation of the various strains and symptoms of those affected. The results clarify that female adolescents with a dual diagnosis PTSD and SUD are currently not sufficiently addressed by the supply system and could benefit from a specific treatment like Seeking Safety.

    The college years are a time for developing independence and separating from one's family, and they are also a time in which substance use often escalates. This study examined the relationships between use of substances and interpersonal guilt, an emotion that can arise from feelings about separation among college students. In total, 1865 college students completed a survey evaluating substance use and interpersonal guilt. Regular users of alcohol, cigarettes, cannabis, and other illicit drugs were compared with nonregular users of each substance. Sequential linear regression, controlling for confounding variables, examined relationships between regular use of each substance and scores on a guilt index. Risky drinkers and daily smokers had significantly more interpersonal guilt than their peers who did not regularly use these substances. In contrast, regular cannabis users had significantly less guilt than nonregular cannabis users. These data suggest that substance use among college students may be related to interpersonal guilt and family separation issues, and this relationship may vary across substances.

  4. Gender differences in substance use disorders.

    Despite the fact that the rate of substance abuse and dependence is higher among men than it is among women, the prevalence rates, especially the more recent ones, indicate that a diagnosis of substance abuse is not gender specific. From the emerging literature on gender differences over the past 25 years, male and female substance abusers are clearly not the same. Women typically begin using substances later than do men, are strongly influenced by spouses or boyfriends to use, report different reasons for maintaining the use of the substances, and enter treatment earlier in the course of their illnesses than do men. Importantly, women also have a significantly higher prevalence of comorbid psychiatric disorders, such as depression and anxiety, than do men, and these disorders typically predate the onset of substance-abuse problems. For women, substances such as alcohol may be used to self-medicate mood disturbances, whereas for men, this may not be true. Although these comorbid disorders might complicate treatment for women, women are, in fact, responsive to treatment and do as well as men in follow-up. Gender differences and similarities have significant treatment implications. This is especially true for the telescoping phenomenon, in which the window for intervention between progressive landmarks is shorter for women than for men. This is also true for the gender differences in physical and sexual abuse, as well as other psychiatric comorbidity that is evident in female substance abusers seeking treatment. The barriers to treatment for women are being addressed in many treatment settings to encourage more women to enter treatment, and family and couples therapy are standard therapeutic interventions. Negative consequences associated with substance abuse are different for men and women, and gender-sensitive rating instruments must be used to measure not only the severity of the problem but also to evaluate treatment efficacy. To determine whether gender

    Since 1993, the New York State Department of Health, funded by the Agency for Toxic Substances and Disease Registry, has collected data about non-petroleum hazardous substances releases through the Hazardous Substances Emergency Events Surveillance (NYHSEES) project. This study investigates risk factors for hazardous substances releases that may result in public health consequences such as injury or reported health effects. The 6428 qualifying events that occurred during the 10-year-period of 1993-2002 involved 8838 hazardous substances, 842 evacuations, more than 75,419 people evacuated, and more than 3120 people decontaminated. These events occurred both at fixed facilities (79%) and during transport (21%). The causative factors most frequently contributing to reported events were equipment failure (39%) and human error (33%). Five of the 10 chemicals most frequently associated with injuries were also among the 10 chemicals most frequently involved in reported events: sulfuric acid, hydrochloric acid, ammonia, sodium hypochlorite, and carbon monoxide. The chemical categories most frequently associated with events, and with events with adverse health effects were volatile organic compounds (VOCs) and solvents, and acids. Events with releases of hazardous substances were associated with injuries to 3089 people including employees (37%), responders (12%), the general public (29%) and students (22%). The most frequently reported adverse health effects were respiratory irritation, headache, and nausea or vomiting. Most of the injured were transported to the hospital, treated, and released (55%) or treated at the scene (29%). These data have been used for emergency response training, planning, and prevention activities to reduce morbidity and mortality from future events

    Objective: Research has documented that sexual minorities are at greater risk for substance use than heterosexuals. However, there are limited studies and mixed findings when investigating these health disparities among racial and ethnic minority samples. We used an intersectionality framework to examine disparities in lifetime substance use problems between heterosexual and sexual minority men and women and within sexual minority groups among a racially diverse sample. Method: A nonprobability sample of heterosexual (n = 1,091) and sexual minority (n = 1,465) patients from an urban community health center ranged in age from 18 to 72 years. Participants completed a brief patient survey and reported demographic information and history of lifetime substance use problems. Logistic regressions analyses were used to examine interactions between and among sexual orientation, gender, and race. Results: We found a significant three-way interaction among sexual orientation, gender, and race. Sexual minorities had a greater risk of self-reported lifetime substance use problems than heterosexuals, with nuanced gender and racial differences. Of greatest note, sexual minority women of color had greater risks than heterosexual women of color and than White sexual minority women. Sexual minority men of color did not differ in their risk when compared with heterosexual men of color, and they had lower risk than White sexual minority men. Conclusions: The results of this study demonstrate that an intersectionality framework is crucial to clearly identify lifetime substance use disparities between racially diverse sexual minority and heterosexual men and women. Future research, treatment, and policy should use intersectionality approaches when addressing substance use disparities. PMID:24411810

  9. A Review of Plant Growth Substances

    2014-10-01

    Full Text Available Plant growth substances are compounds, either natural or synthetic that modifies or controls through physiological action, the growth and maturation of plants. If the compound is produced within the plant, it is called a plant hormone or phytohormone. In general, it is accepted that there are five major classes of plant hormones. They are Auxins (IAA, Cytokinins, Gibberellins, Ethylene and Abscisic Acid. However, there are still many plant growth substances that cannot be grouped under these classes, though they also perform similar functions, inhibiting or promoting plant growth. These substances include Brassinosteroids (Brassins, Salicylic Acid, Jasmonic Acid, Fusicoccin, Batasins, Strigolactones, Growth stimulants (e.g. Hymexazol and Pyripropanol, Defoliants (e.g. Calcium Cyanamide, Dimethipin. Researchers are still working on the biosynthetic pathways of some of these substances. Plant growth substances are very useful in agriculture in both low and high concentrations. They affect seed growth, time of flowering, the sex of flowers, senescence of leaves and fruits, leaf formation, stem growth, fruit development and ripening, plant longevity, and even plant death. Some synthetic regulators are also used as herbicides and pesticides. Therefore, attention should be paid to the production and synthesis of these substances so that they affect plants in a way that would favour yield.

    2010-01-01

    Objective: Although much research has explored the relation of substance-use norms to substance use among college students, much less research has focused on employed adults and the workplace as a social context for social norms regarding substance use. This study explored the relation of descriptive and injunctive workplace substance-use norms regarding alcohol and illicit drug use to employee substance use. Both alcohol use and illicit drug use were explored, as well as overall and context-specific use and impairment. Method: Data were collected from a national probability sample of 2,430 employed adults (55% female) using a random-digit-dial telephone survey. Overall employee alcohol and illicit drug use were assessed, as well as use before work, use and impairment during the workday, and use after work. Results: After controlling for a number of potential covariates, injunctive norms regarding workplace alcohol and illicit drug use predicted substance use and impairment overall and across all contexts of use. Descriptive norms predicted alcohol and illicit drug use before and during work, as well as workplace impairment. Conclusions: This study shows that both workplace injunctive and descriptive norms are important predictors of substance use in the U.S. workforce. There were two general patterns, however, that were consistent across both alcohol and illicit drug use. Social norms marketing campaigns, therefore, may be a useful way for employers to target employee substance use. The present results also helped to integrate the results of several prior studies that employed narrower samples and measures. PMID:20553660

    2018-02-01

    Full Text Available Context: The care of the ozone layer is an activity that contributes to the planet's environmental stability. For this reason, the Montreal Protocol is created to control the emission of substances that deplete the ozone layer and reduce its production from an organizational point of view. However, it is also necessary to have control of those that are already circulating and those present in the equipment that cannot be replaced yet because of the context of the companies that keep it. Generally, the control mechanisms for classifying the type of substances, equipment and companies that own them, are carried in physical files, spreadsheets and text documents, which makes it difficult to control and manage the data stored in them. Method: The objective of this research is to computerize the process of control of substances that deplete the ozone layer. An evaluation and description of all process to manage Ozone-Depleting Substances (ODS, and its alternatives, is done. For computerization, the agile development methodology SCRUM is used, and for the technological solution tools and free open source technologies are used. Result: As a result of the research, a computer tool was developed that automates the process of control and management of substances that exhaust the ozone layer and its alternatives. Conclusions: The developed computer tool allows to control and manage the ozone-depleting substances and the equipment that use them. It also manages the substances that arise as alternatives to be used for the protection of the ozone layer.

  15. Adolescent Suicidal Behavior and Substance Use: Developmental Mechanisms

    Directory of Open Access Journals (Sweden)

    Donald M. Dougherty

    2008-01-01

    Full Text Available Adolescent suicidal behaviors and substance use are disturbingly common. Research suggests overlap of some of the etiological mechanisms for both adolescent suicidal behavior and substance use, yet clear understanding of the complex relations between these behaviors and their causal underpinnings is lacking. A growing body of evidence and a diathesis model (Mann et al. 1999; Mann, 2003 highlight the importance of impulse control as a proximal risk factor for adolescent suicidal and substance use behaviors. This literature review extends current theory on the relationships between adolescent suicidal behavior and substance use by: (1 examining how, when, and to what extent adolescent development is affected by poor impulse control, stressful life events, substance use behavior, and biological factors; (2 presenting proposed causal mechanisms by which these risk factors interact to increase risk for suicidal behaviors and substance use; and (3 proposing specific new hypotheses to extend the diathesis model to adolescents at risk for suicide and substance use. More specifically, new hypotheses are presented that predict bidirectional relationships between stressful life events and genetic markers of 5-HT dysregulation; substance use behavior and impulsivity; and substance use behavior and suicide attempts. The importance of distinguishing between different developmental trajectories of suicidal and substance use behaviors, and the effects of specific risk and protective mechanisms are discussed. Use of new statistical approaches that provide for the comparison of latent growth curves and latent class models is recommended to identify differences in developmental trajectories of suicidal behavior and substance use. Knowledge gained from these prospective longitudinal methods should lead to greater understanding on the timing, duration, and extent to which specific risk and protective factors influence the outcomes of suicidal behavior and substance

    Substance abuse is a growing, but mostly silent, epidemic among older adults. We sought to analyze the trends in admissions for substance abuse treatment among older adults (aged 55 and older). Treatment Episode Data Set - Admissions (TEDS-A) for period between 2000 and 2012 was used. The trends in admission for primary substances, demographic attributes, characteristics of substance abused and type of admission were analyzed. While total number of substance abuse treatment admissions between 2000 and 2012 changed slightly, proportion attributable to older adults increased from 3.4% to 7.0%. Substantial changes in the demographic, substance use pattern, and treatment characteristics for the older adult admissions were noted. Majority of the admissions were for alcohol as the primary substance. However there was a decreasing trend in this proportion (77% to 64%). The proportion of admissions for following primary substances showed increase: cocaine/crack, marijuana/hashish, heroin, non-prescription methadone, and other opiates and synthetics. Also, admissions for older adults increased between 2000 and 2012 for African Americans (21% to 28%), females (20% to 24%), high school graduates (63% to 75%), homeless (15% to 19%), unemployed (77% to 84%), and those with psychiatric problems (17% to 32%).The proportion of admissions with prior history of substance abuse treatment increased from 39% to 46% and there was an increase in the admissions where more than one problem substance was reported. Ambulatory setting continued to be the most frequent treatment setting, and individual (including self-referral) was the most common referral source. The use of medication assisted therapy remained low over the years (7% - 9%). The changing demographic and substance use pattern of older adults implies that a wide array of psychological, social, and physiological needs will arise. Integrated, multidisciplinary and tailored policies for prevention and treatment are necessary to

    Abnormal uterine bleeding (AUB) is the major complaint in approximately one-third of gynecological visits in premenopausal women, and in >70% of appointments of perimenopausal and postmenopausal women. Uterine myoma is one of the main causes of AUB during menacme, especially when it is submucosal. The association of myoma and AUB may be related to several factors, from local alterations of angiogenic and vasoactive substances to changes in uterine contractility. The objective of this paper is to show the different associations of myoma and AUB. Copyright © 2016. Published by Elsevier Ltd.

    Erectile dysfunction very frequently can be traced back to the real cause by means of angiography. Selective angiography is the method of choice in cases where other causes of circulatory disturbance have already been excluded, and non-invasive tests are expected to yield information of relevance to therapy. The qualitatively best angiographic results are obtained by examination under peridural anesthesia and by intracavitary injection of vaso-active substances. Selective arteriography is indicated in cases of primary or post-traumatic erectile dysfunction. It is a prerequisite of surgery for revascularisation of the pudendal-penile vascular bed.

    Hernandez, Lynn; Rodriguez, Ana Maria; Spirito, Anthony

    2015-01-01

    Synopsis Research has consistently shown that a lack of parental involvement in the activities of their children predicts initiation and escalation of substance use. Parental monitoring, as well as youth disclosure about their whereabouts, parent child communication, positive parenting and family management strategies, e.g., consistent limit setting, and parental communication about and disapproval of substance use, have all been shown to protect against adolescent substance abuse and substance problems. Given the empirical evidence, family and parenting approaches to preventing and intervening on adolescent substance misuse have received support in the literature. This article discusses the theoretical foundations as well as the application of the Family Check-up, a brief family-based intervention for adolescent substance use. PMID:26092741

    Full Text Available Introduction: Substance use including tobacco and alcohol is the most important cause of preventable morbidity, disability, and premature mortality. The study aims to specify the prevalence and the pattern of use of different substance. Methods: A cross sectional study was performed amongst first year and final year students in four medical colleges in Kathmandu using self administered anonymous questionnaire.Data collectedfrom 446 students were analyzed. Results: Prevalence of substance use was found to be 60.3% among the medical students. Alcohol (57.6% was the substance most prevalently used followed by tobacco (27.58% and cannabis (12.8%. Mean age of first exposure was 17.94 (Confidence interval: 17.91-17.97. There was significant difference in the useof tobacco and cannabis amongst final year students than first year students. Male and female differed significantly in use of every substance except for benzodiazepine. Medical college, college and school were place of first exposure in 17.26%, 15.92% and 13.23% of the cases respectively. Family history was associated with substance use in medical students and was statistically significant (P<0.0001.Experimentation was the major reason for the use of most of the substances. Conclusions: Substance use is prevalent in male medical students of both first and final year. Hence steps should be initiated early in school, college and medical college to prevent substance use.

    The aim of the present research programme is to study the complexation behaviour of actinide ions with humic substances in natural aquifer systems and hence to quantify the effect of humic substances on the actinide migration. Aquatic humic substances commonly found in all groundwaters in different concentrations have a strong tendency towards complexation with actinide ions. This is one of the major geochemical reactions but hitherto least quantified. Therefore, the effect of humic substances on the actinide migration is poorly understood. In the present research programme the complexation of actinide ions with humic substances will be described thermodynamically. This description will be based on a model being as simple as possible to allow an easy introduction of the resulting constants into geochemical modelling of the actinide migration. This programme is a continuation of the activities of the COCO group in the second phase of the CEC-MIRAGE project. (orig.)

  7. Epidemiology of Substance Use in Reproductive-Age Women

    McHugh, R. Kathryn; Wigderson, Sara; Greenfield, Shelly F.

    2014-01-01

    Synopsis A significant number of women of reproductive age in the U.S. use addictive substances. In 2012 more than 50% reported current use of alcohol, 20% used tobacco products, and approximately 13% used other drugs. Among women, use of these substances is associated with a number of significant medical, psychiatric, and social consequences, and the course of illness may progress more rapidly in women than men. The lifetime prevalence of alcohol and drug use disorders in women is 19.5% and 7.1%, respectively. In addition, as most addictive substances cross the placenta and have deleterious effects on fetal development, substance use has additional potential adverse consequences for women of reproductive age who may become pregnant. Specific barriers to accessing effective substance use treatment exist for women. The prevalence of substance use and evidence of accelerated illness progression in women highlight the importance of universal substance use screening in women in primary care settings.

  9. Vasodilatory effect of the stable vasoactive intestinal peptide analog RO 25-1553 in murine and rat lungs.

    Directory of Open Access Journals (Sweden)

    Jun Yin

    Full Text Available Stable analogs of vasoactive intestinal peptide (VIP have been proposed as novel line of therapy in chronic obstructive pulmonary disease (COPD based on their bronchodilatory and anti-inflammatory effects. We speculated that VIP analogs may provide additional benefits in that they exert vasodilatory properties in the lung, and tested this hypothesis in both ex vivo and in vivo models.In isolated perfused mouse lungs and in an in vivo rat model, pulmonary blood vessels were preconstricted by hypoxia and hemodynamic changes in response to systemic (ex vivo or inhaled (in vivo administration of the cyclic VIP analog RO 25-1553 were determined.In mouse lungs, RO 25-1553 reduced intrinsic vascular resistance at normoxia, and attenuated the increase in pulmonary artery pressure in response to acute hypoxia. Consistently, inhalation of RO 25-1553 (1 mg · mL(-1 for 3 min caused an extensive and sustained (> 60 min inhibition of the pulmonary arterial pressure increase in response to hypoxia in vivo that was comparable to the effects of inhaled sildenafil. This effect was not attributable to systemic cardiovascular effects of RO 25-1553, but to a lung specific reduction in pulmonary vascular resistance, while cardiac output and systemic arterial hemodynamics remained unaffected. No adverse effects of RO 25-1553 inhalation on pulmonary gas exchange, ventilation-perfusion matching, or lung fluid content were detected.Our findings demonstrate that inhaled delivery of the stable VIP analog RO 25-1553 induces a potent and sustained vasodilatory effect in the pulmonary circulation with no detectable adverse effects. Therapeutic inhalation of RO 25-1553 may provide vascular benefits in addition to its reported anti-inflammatory and bronchodilatory effects in COPD, yet caution is warranted given the overall poor results of vasodilator therapies for pulmonary hypertension secondary to COPD in a series of recent clinical trials.

    2015-01-01

    To date studies have not explored patterns of substance use exclusively among youth in the child welfare system. Consequently, little is known about polysubstance use among child welfare-involved youth. This study aimed to explore whether physical abuse, parental substance use, depression, and demographic characteristics predict distinct patterns of substance use among child welfare-involved youth using latent class analysis (LCA). The sample included 822 11-17 year olds who participated in the National Survey of Child and Adolescent Well-being (NSCAW II) study between March 2008 and September 2009. We found the following three classes: (1) polysubstance use, (2) alcohol and marijuana use, and (3) low use. Older youth and youth who experienced physical abuse were at greater risk of being in the polysubstance use class, while living with a biological parent reduced the likelihood of polysubstance use class membership. Youth in the alcohol and marijuana use class were more likely to be older and depressed. Results from this study illuminate important targets for interventions.

  11. From substance use to homelessness or vice versa?

    McVicar, Duncan; Moschion, Julie; van Ours, Jan C

    2015-07-01

    Homelessness is associated with substance use, but whether substance use precedes or follows homelessness is unclear. We investigate the nature of the relationship between homelessness and substance use using data from the unique Australian panel dataset Journeys Home collected in 4 surveys over the period from October 2011 to May 2013. Our data refer to 1325 individuals who were homeless or at risk of becoming homeless. We investigate dynamics in homelessness and substance use over the survey period. We find that the two are closely related: homeless individuals are more likely to be substance users and substance users are more likely to be homeless. These relationships, however, are predominantly driven by observed and unobserved individual characteristics which cause individuals to be both more likely to be homeless and to be substance users. Once we take these personal characteristics into account it seems that homelessness does not affect substance use, although we cannot rule out that alcohol use increases the probability that an individual becomes homeless. These overall relationships also hide some interesting heterogeneity by 'type' of homelessness. Copyright © 2015 Elsevier Ltd. All rights reserved.

    There are persistent concerns of long-term effects of stimulant ADHD medication on the development of substance abuse. Using Swedish national registers, we studied all individuals born between 1960 and 1998 and diagnosed with ADHD (26,249 men and 12,504 women). We investigated the association between stimulant ADHD medication in 2006 and substance abuse during 2009. Substance abuse was indexed by substance-related death, crime, or hospital visits. ADHD medication was not associated with increased rate of substance abuse. Actually, the rate during 2009 was 31% lower among those prescribed ADHD medication in 2006, even after controlling for medication in 2009 and other covariates (hazard ratio: 0.69; 95% confidence interval: 0.57-0.84). Also, the longer the duration of medication, the lower the rate of substance abuse. Similar risk reductions were suggested among children and when investigating the association between stimulant ADHD medication and concomitant short-term abuse. We found no indication of increased risks of substance abuse among individuals prescribed stimulant ADHD medication; if anything, the data suggested a long-term protective effect on substance abuse. Although stimulant ADHD medication does not seem to increase the risk for substance abuse, clinicians should remain alert to the potential problem of stimulant misuse and diversion in ADHD patients. © 2013 The Authors.

By areas, the official masters more offered have been the ones of nutrition and alimentary security. 76,33% of the official masters have a length of 1 academic year. Almost the half of the official masters have an orientation researcher-professional and almost 40% researcher. 62,65% of the masters give of face-to-face way. In 52,1% of the official masters do not realise external practices and 86,2% has continuity with the doctorate.Conclusions: It has seen that it is necessary that expand the number of masters including other fields of study that contribute to a main specialisation of the professionals of the infirmary. An important percentage of official masters give in face-to-face modality, and there is very few offered on-line or to distance.

  14. Acculturation factors and substance use among Asian American youth.

    2009-07-01

    In this study of 329 Cambodian, Chinese, Laotian/Mien, and Vietnamese youth in Oakland, California, acculturation factors of individualism-collectivism and acculturative dissonance were examined as risk and protective factors for substance use. Results of structural equation modeling and bootstrapping revealed that peer substance use was a robust mediator between individualism and youth's self-reported substance use, particularly among Vietnamese and males. Peer substance use also significantly mediated the relation between collectivism and substance use for females. As such, there appears to be ethnic and gender group variations in the saliency of cultural/acculturation factors with respect to substance use. Implications for substance use prevention programs for ethnic and immigrant youth are discussed.

    The distribution of vasoactive intestinal peptide (VIP) binding sites in the pigeon brain was examined by in vitro autoradiography on slide-mounted sections. A fully characterized monoiodinated form of VIP, which maintains the biological activity of the native peptide, was used throughout this study. The highest densities of binding sites were observed in the hyperstriatum dorsale, archistriatum, auditory field L of neostriatum, area corticoidea dorsolateralis and temporo-parieto-occipitalis, area parahippocampalis, tectum opticum, nucleus dorsomedialis anterior thalami, and in the periventricular area of the hypothalamus. Lower densities of specific binding occurred in the neostriatum, hyperstriatum ventrale and nucleus septi lateralis, dorsolateral area of the thalamus, and lateral and posteromedial hypothalamus. Very low to background levels of VIP binding were detected in the ectostriatum, paleostriatum primitivum, paleostriatum augmentatum, lobus parolfactorius, nucleus accumbens, most of the brainstem, and the cerebellum. The distribution of VIP-containing fibers and terminals was examined by indirect immunofluorescence using a polyclonal antibody against porcine VIP. Fibers and terminals were observed in the area corticoidea dorsolateralis, area parahippocampalis, hippocampus, hyperstriatum accessorium, hyperstriatum dorsale, archistriatum, tuberculum olfactorium, nuclei dorsolateralis and dorsomedialis of the thalamus, and throughout the hypothalamus and the median eminence. Long projecting fibers were visualized in the tractus septohippocampalis. In the brainstem VIP immunoreactive fibers and terminals were observed mainly in the substantia grisea centralis, fasciculus longitudinalis medialis, lemniscus lateralis, and in the area surrounding the nuclei of the 7th, 9th, and 10th cranial nerves

    Vasoactive intestinal peptide (VIP) is known to regulate proliferation or differentiation in normal and tumoral cells. SH-SY5Y is a differentiated cell subclone derived from the SK-N-SH human neuroblastoma cell line and possess all the components for an autocrine action of VIP. In the present study, we investigated the morphological changes and intracellular signaling pathways occurring upon VIP treatment of SH-SY5Y cells. VIP induced an early remodeling of cell projections: a branched neurite network spread out and prominent varicosities developed along neurites. Although activated by VIP, the Ras/ERK pathway was not required for the remodeling process. In contrast, pull-down experiments revealed a strong Cdc42 activation by VIP while expression of a dominant-negative Cdc42 prevented the VIP-induced neurite changes, suggesting an important role for this small GTPase in the process. These data provide the first evidence for a regulation of the activity of Rho family GTPases by VIP and bring new insights in the signaling pathways implicated in neurite remodeling process induced by VIP in neuroblastoma cells

    Suicidality is more commonly reported among individuals with addictions relative to the general population, though data from Asian countries remain scarce. The medical records of 2187 Singaporean patients with drug (n=879), alcohol (n=754) or gambling (n=554) disorders entering an outpatient treatment service were examined to explore differences in suicidal ideation and lifetime attempts between substance and gambling addictions. The relationship between suicidality, co-morbidity and addiction severity were also examined. 25.0% reported thoughts of suicide in the past month, 11.8% had a suicide plan and 12.2% reported lifetime attempts. Rates of suicidal ideation (thoughts, and plan) but not lifetime attempts were significantly higher among gambling than substance use patients. Co-morbid (DSM-IV axis-1) disorders were found among 32.5%, 38% and 40% of those reporting thoughts, plan and lifetime attempts respectively. Addiction severity was higher and quality of life lower among those reporting suicidal behaviors. Logistic regression revealed co-morbidity, debt, gender (being female) and being a gambling patient as significant predictors of suicidal behaviors. The findings highlight the importance of screening for suicidality, even in the absence of co-morbidity, particularly among gambling disorder patients with debts. Suicide risk should be assessed periodically and referral to suicidal prevention interventions routinely offered to this vulnerable population. Copyright © 2014 Elsevier Ireland Ltd.

    Media-related cognitions are a unique influence on adolescents' substance use outcomes even after accounting for the powerful influence of parent and peers. This cross-sectional study expands upon prior research by investigating the impact of media-related cognitions on children's alcohol and tobacco outcomes in the context of parental and peer substance use. Six hundred forty-nine elementary school children (M = 9.4 years of age, SD = 1.1 years; 51 % female) completed self-report questionnaires. After accounting for peer and parental substance use, children's media-related cognitions were independently associated with three outcomes: preferences for alcohol-branded merchandise, moral beliefs about underage alcohol and tobacco use, and intentions to use alcohol and tobacco. Children's perceptions of the desirability and realism of alcohol and tobacco ads--and their similarity to and identification with these ads--predicted greater intentions to use. Desirability and identification with alcohol and tobacco ads were associated with stronger preferences for alcohol-branded merchandise, and understanding advertising's persuasive intent predicted weaker preferences. Media deconstruction skills predicted stronger beliefs that underage alcohol and tobacco use is wrong. Peer and parental substance use were associated with stronger substance-use intentions among children and weaker feelings that substance use is wrong. The findings highlight the role of media influence in contributing to youth substance use and the potential role of media literacy education in the early prevention of substance use.

    2011-01-01

    Motivation to change substance use behavior is an important component of the recovery process that has usually been studied at entry into treatment. Less studied, but equally important, is the measurement of motivation over time and the role motivation plays in subsequent substance use. The present study sought to examine longitudinal motivation toward sobriety among residents of sober living houses. Sober living residents (n = 167) were followed at 6-month intervals over an 18-month period and assessed for motivation and substance use outcomes at each study interview. Motivation was measured using the costs and benefits subscales of the Alcohol and Drug Consequences Questionnaire (ADCQ) and substance use outcomes included the Addiction Severity Index (ASI) alcohol scale, ASI drug scale, and peak density of substance use (number of days of most use in a month). Participants reported higher benefits than costs of sobriety or cutting down substance use at every study time point. Using lagged generalized estimating equation models, the ADCQ costs predicted increased severity for alcohol, drugs, and peak density, whereas the benefits subscale predicted decreased drug and peak density. Longitudinal measurement of motivation can be a useful clinical tool to understand later substance use problems. Given the mixed findings from prior studies on the effects of baseline motivation, a shift toward examining longitudinal measures of motivation at proximal and temporal intervals is indicated.

  5. Women and substance abuse: gender, age, and cultural considerations.

    Stevens, Sally J; Andrade, Rosi A C; Ruiz, Bridget S

    2009-01-01

    Historically, data has shown that a smaller percentage of women use alcohol and illicit substances compared to men, and that frequency of use has been lower among women compared to use among men. Although this data on usage may be true, researchers also acknowledge that substance use among women has been a hidden issue, one not realistically acknowledged by society, especially prior to the mid-1960s. Along with this, more recent data indicates that rates of substance use among women are increasing. Factors contributing to this increase in substance abuse have begun to receive considerable attention, and recent research suggests that many issues exist that are unique to substance use among women. The purpose of this article is to discuss gender specific considerations in women's substance abuse by examining the history of substance use among women; analyzing gender-specific factors, including physiological factors, trauma-related factors, mental health issues, and cultural considerations that impact on women's substance use; articulating treatment approaches for working with substance abusing women and girls; and providing recommendations for further research in this area.

    2012-04-01

    Anaesthesiologists have a significantly higher frequency of substance abuse by a factor of nearly 3 when compared with other physicians. This is still a current problem that must be reviewed. Many hypotheses have been formulated to explain why anaesthesiologists appear to be more susceptible to substance abuse than other medical professionals (genetic differences in sensitivity to opioids, stress, the association between chemical dependence and other psychopathology or the second-hand exposure hypothesis). Environmental exposure and sensitization may be an important risk factor in physician addiction. There is a long debate about returning to work for an anaesthetist who has been depending on opioid drugs, and recent debates are discussed. Institutional efforts have been made in many countries and physician health programmes have been developed. As drug abuse among anaesthesiologists has continued, new studies have been conducted to know the theories about susceptibility. Written substance abuse policies and controls must be taken in place and in all countries.

    To explore patterns and levels of self-esteem of pregnant substance abusers. A descriptive prospective study to describe the self-esteem of pregnant substance abusers. Subjects (N = 31) were abusing and dependent on three or more legal and/or illegal substances. Subjects were asked one open-ended question regarding their self-esteem, then the Rosenberg Self-Esteem Inventory (RSI) was administered. Subjects gave 46 responses to the open-ended question. Overall, they used a single word to describe self-esteem. The most frequent response on the RSI was "low" for self-esteem, 23 subjects used positive terms, 20 used negative terms, and 3 reported a neutral term. The RSI confirmed the aspects of low self-esteem. Problems with low self-esteem were evident. Intervention strategies need to be developed to increase self-esteem in pregnant substance abusers.

  20. The natural history of substance use disorders.

    Sarvet, Aaron L; Hasin, Deborah

    2016-07-01

    Illicit drugs, alcohol, and tobacco use disorders contribute substantially to the global burden of disease. Knowledge about the major elements of the natural history of substance use disorders (incidence, remission, persistence, and relapse) is crucial to a broader understanding of the course and outcomes of substance use disorders. Prospective cohort studies in nonclinical samples indicate that externalizing psychopathology in earlier life, including early disordered substance use, delinquency, and personality disorders, are related to substance use disorders later in life and chronic course. Externalizing psychopathology may be initiated by early adverse experiences, for example, childhood maltreatment and stressful life events. After controlling for confounders, 'age at first use' as a causal factor for alcohol use disorder later in life and the 'drug substitution' hypothesis are not supported in general population data. Future research should focus on elaborating the causal framework that leads to the development and persistence of severe substance use disorders, with an emphasis on identifying modifiable factors for intervention by policy makers or health professionals. More research is needed on the natural history of substance use disorders in low-income and middle-income countries.

  1. The role of substance use motives in the associations between minority stressors and substance use problems among young men who have sex with men.

    Science.gov (United States)

    Feinstein, Brian A; Newcomb, Michael E

    2016-09-01

    Young men who have sex with men (YMSM) report higher rates of substance use than their heterosexual peers and minority stress has been posited as a risk factor for substance use. The associations between specific types of minority stress and substance use have been inconsistent throughout the literature and few studies have examined mechanisms underlying these associations. Drawing on minority stress theory and the motivational model of alcohol use, we propose that one mechanism underlying these associations may be people's motivations for using substances, including using substances to cope with negative emotions and to enhance pleasure. The goals of the current study were: (1) to examine the associations among minority stressors, substance use motives, and substance use problems; and (2) to examine substance use motives as mediators of the associations between minority stressors and substance use problems. Baseline self-report data were used from a cohort of 370 YMSM enrolled in a larger study of substance use and sexual behavior. Results indicated that using marijuana to cope mediated the association between victimization and marijuana use problems. Using other drugs to cope mediated the associations between victimization and drug use problems and between internalized stigma and drug use problems. Drinking to cope and to enhance pleasure mediated the association between internalized stigma and alcohol use problems. In sum, substance use motives, especially using substances to cope, act as mechanisms through which certain types of minority stress influence substance use problems among YMSM.

    2014-02-01

    Barriers to both mental health and substance use disorder treatments have rarely been examined among individuals with comorbid mental health and substance use disorders. In a sample of 393 adults with 12-month major depressive episodes and substance use disorders, we compared perceived barriers to these two types of treatments. Data were drawn from the 2005-2011 U.S. National Surveys on Drug Use and Health. Overall, the same individuals experienced different barriers to mental health treatment versus substance use disorder treatment. Concerns about negative views of the community, effects on job, and inconvenience of services were more commonly reported as reasons for not receiving substance use disorder treatment. Not affording the cost of care was the most common barrier to both types of treatments, but more commonly reported as a barrier to mental health treatment. Improved financial access through the Affordable Care Act and parity legislation and integration of mental health and substance use disorder services may help to reduce treatment barriers among individuals with comorbid mental health and substance disorders. © 2013.

    2007-09-01

    The study documents the characteristics of Hong Kong residents who used substances in mainland China. Characteristics of such users were compared with those using substances elsewhere. A cross-sectional survey was used. Data analyses were stratified by gender, and multivariate analyses were performed. Respondents, Hong Kong adults aged 18-30 (n = 6,528), were interviewed using a mixed interviewer and computerized mobile phone method, at the Hong Kong-mainland China boundary. Cross-border substance users and other types of substance users had characteristics that were quite different (e.g., education level, perceived harmfulness of substance use in general, having friends who frequently used substances in mainland China). Cross-boundary substance users also found it easier to obtain substances in mainland China than in Hong Kong (males: 60.5%, females: 39.6%) and perceived no chance of being arrested in mainland China because of substance use (men: 28.8%, women: 24.5%). They tended to use substances in discos/rave parties together with friends (men: 77%, women: 81%), and substances were often obtained for free (men: 63.2%, women: 78%). Ecstasy and ketamine were often used (men: 86.5% & 79.4%, women: 81% & 70.2%), and multiple uses of different substances were common (men: 81.3%, women: 68.6%). Lower price, peer influence, and better availability were reasons behind cross-boundary substance use behaviors. Cross-boundary substance users have specific characteristics. Prevention policies should take these characteristics into account. Regional collaborations are highly warranted.

    Lower rates of substance abuse are found among Black Americans compared to Whites, but little is known about differences in substance abuse across ethnic groups within the black population. We examined prevalence rates of substance abuse among Blacks across three geographic regions (US, Jamaica, Guyana). The study also sought to ascertain whether length of time, national context and major depressive episodes (MDE) were associated with substance abuse. We utilized three different data sources based upon probability samples collected in three different countries. The samples included 3,570 African Americans and 1,621 US Caribbean Black adults from the 2001-2003 National Survey of American Life (NSAL). An additional 1,142 Guyanese Blacks and 1,176 Jamaican Blacks living in the Caribbean region were included from the 2005 NSAL replication extension study, Family Connections Across Generations and Nations (FCGN). Mental disorders were based upon DSM-IV criteria. For the analysis, we used descriptive statistics, chi-square, and multivariate logistic regression analytic procedures. Prevalence of substance abuse varied by national context, with higher rates among Blacks within the United States compared to the Caribbean region. Rates of substance abuse were lower overall for women, but differ across cohorts by nativity and length of time in the United States, and in association with major depressive episode. The study highlights the need for further examination of how substance abuse disparities between US-based and Caribbean-based populations may become manifested.

    Siddharth Sarkar

    2014-01-01

    Full Text Available Background: Harm ratings of substances help in understanding the perception toward substance use and formulating policies. Evidence of such harm ratings by substance users and their caregivers provides a clearer perspective of those who experience and observe such harm closely. Materials and Methods: Substance users and their caregivers were recruited from the Drug De-addiction and Treatment Centre of PGIMER, Chandigarh. Sociodemographic details of the subjects were noted. The subjects were then asked to rate a list of psychoactive preparations according to the harms they thought the preparation caused. The list of substances was developed taking into consideration substance commonly encountered in the geographical area. The harm ratings were transformed on a scale of 0-100. Results: All subjects were males and majority of them were educated above 10 th standard, were not employed and belonged to urban background. Most of them had taken psychoactive substances in their lifetimes but were currently abstinent. Most of the subjects endorsed intravenous drugs as the most harmful, followed by heroin. Beer and chewable tobacco considered the least harmful substances. Greater degree of education was associated with lower harm rankings for heroin, cannabis, dextropropoxyphene, and raw opium; while urban residence was associated with greater harm ratings for cannabis and raw opium. Differences in the harms were perceived for different preparations of the same active compound for alcohol and nicotine. Conclusion: Harm ratings of substances can be a useful guide while formulating policies and allocating resources. Need for further research extending this pilot study is emphasized.

  16. Employer health insurance offerings and employee enrollment decisions.

    Polsky, Daniel; Stein, Rebecca; Nicholson, Sean; Bundorf, M Kate

    2005-10-01

    To determine how the characteristics of the health benefits offered by employers affect worker insurance coverage decisions. The 1996-1997 and the 1998-1999 rounds of the nationally representative Community Tracking Study Household Survey. We use multinomial logistic regression to analyze the choice between own-employer coverage, alternative source coverage, and no coverage among employees offered health insurance by their employer. The key explanatory variables are the types of health plans offered and the net premium offered. The models include controls for personal, health plan, and job characteristics. When an employer offers only a health maintenance organization married employees are more likely to decline coverage from their employer and take-up another offer (odds ratio (OR)=1.27, phealth plan coverage an employer offers affects whether its employees take-up insurance, but has a smaller effect on overall coverage rates for workers and their families because of the availability of alternative sources of coverage. Relative to offering only a non-HMO plan, employers offering only an HMO may reduce take-up among those with alternative sources of coverage, but increase take-up among those who would otherwise go uninsured. By modeling the possibility of take-up through the health insurance offers from the employer of the spouse, the decline in coverage rates from higher net premiums is less than previous estimates.

    Eitle, David

    2005-06-01

    This study examines the association between family structure and adolescent substance use, specifically focusing on the potential conditioning effects of the level of exposure to substance-using peers. Using data from a statewide study of Florida students, tobacco, alcohol, marijuana, and other illicit drug use was regressed on measures of family structure, exposure to deviant peers, family process variables (including supervision, attachment, and discipline), and an array of salient predictors of adolescent substance use. Logistic regression analyses revealed that the level of exposure to substance-using peers moderates the relationship between family structure and substance use for three of the four dependent variables. The core finding is that living with two natural parents serves as a protective factor against using tobacco, alcohol, or other illicit drugs, but only under conditions when exposure to deviant peers is lowest. Under conditions when exposure to deviant peers is highest, teens residing in a traditional two-parent family are most likely to report substance use. However, some evidence suggests that this latter finding may be due to differences in the duration of exposure to deviant peers. These findings reinforce the need to continue to explore how the quantity of parenting may provide additional protection against adolescent substance use beyond quality of parenting factors.

  19. Topiramate in the treatment of substance related disorders: a critical review of the literature

    Shinn, Ann K.; Greenfield, Shelly F.

    2013-01-01

    Objective To critically review the literature on topiramate in the treatment of substance related disorders. Data Sources A PubMed search of human studies published in English through January 2009. Study Selection 26 articles were identified and reviewed; these studies examined topiramate in disorders related to alcohol, nicotine, cocaine, methamphetamine, opioids, ecstasy, and benzodiazepines. Data Extraction Study design, sample size, topiramate dose and duration, and study outcomes were reviewed. Data Synthesis There is compelling evidence for the efficacy of topiramate in the treatment of alcohol dependence. Two trials show trends for topiramate’s superiority over oral naltrexone in alcohol dependence, while one trial suggests topiramate is inferior to disulfiram. Despite suggestive animal models, evidence for topiramate in treating alcohol withdrawal in humans is slim. Studies of topiramate in nicotine dependence show mixed results. Human laboratory studies that used acute topiramate dosing show that topiramate actually enhances the pleasurable effects of both nicotine and methamphetamine. Evidence for topiramate in the treatment of cocaine dependence is promising, but limited by small sample size. The data on opioids, benzodiazepines, and ecstasy are sparse. Conclusion Topiramate is efficacious for the treatment of alcohol dependence, but side effects may limit widespread use. While topiramate’s unique pharmacodynamic profile offers a promising theoretical rationale for use across multiple substance related disorders, heterogeneity both across and within these disorders limits topiramate’s broad applicability in treating substance related disorders. Recommendations for future research include exploration of genetic variants for more targeted pharmacotherapies. PMID:20361908

    Chapman, Shawna L. Carroll; Wu, Li-Tzy

    2013-01-01

    National survey data suggest that new mothers have high prevalences of alcohol and illicit drug use. Depression correlates with substance use, and new mothers with postpartum depression (PPD) may be at high risk for substance use. Understanding postpartum substance use and its relationship to PPD can inform future research and intervention. A literature search was conducted resulting in 12 studies published from 1999–2012 examining postpartum alcohol use, drug use, or combined postpartum depression and substance use. Postpartum alcohol (prevalence range 30.1%−49%) and drug use (4.5%–8.5%) were lower than use among not pregnant, not postpartum women (41.5%–57.5%; 7.6%–10.6%, respectively) but higher than use among pregnant women (5.4%–11.6%; 3.7%–4.3%, respectively). Correlates of postpartum problem drinking were being unemployed, unmarried, and a cigarette smoker. Prevalence of drug use was highest among white new mothers, followed by Blacks and Hispanics, but Black new mothers appeared at greater risk of drug use. No identified studies examined correlates of postpartum drug use beyond race/ethnicity. Postpartum depressive symptoms were prevalent among postpartum substance users and those with a substance use history (19.7%–46%). The postpartum period is a critical time. Prevalent substance use and the scarcity of studies warrant research to identify means to reduce maternal substance use. PMID:23879459

    2013-12-01

    To assess the link between childhood attention problems (AP) and substance use 18 years later. This cohort study was conducted in a community sample of 1103 French youths followed from 1991 to 2009. Exposures and covariates were childhood behavioral problems (based on parental report at baseline), early substance use, school difficulties, and family adversity. Outcome measures were regular tobacco smoking, alcohol problems, problematic cannabis use, and lifetime cocaine use (based on youth reports at follow-up). Individuals with high levels of childhood AP had higher rates of substance use (regular tobacco smoking, alcohol problems, problematic cannabis use, and lifetime cocaine use). However, when taking into account other childhood behavioral problems, early substance use, school difficulties, and family adversity, childhood AP were related only to regular tobacco smoking and lifetime cocaine use. Early cannabis exposure was the strongest risk factor for all substance use problems. This longitudinal community-based study shows that, except for tobacco and cocaine, the association between childhood AP and substance use is confounded by a range of early risk factors. Early cannabis exposure plays a central role in later substance use. Copyright © 2013 Mosby, Inc. All rights reserved.

    Richardson, George B; Chen, Ching-Chen; Dai, Chia-Liang; Swoboda, Christopher M

    2014-11-03

    This study tested whether life history strategy (LHS) and its intergenerational transmission could explain young adult use of common psychoactive substances. We tested a sequential structural equation model using data from the National Longitudinal Survey of Youth. During young adulthood, fast LHS explained 61% of the variance in overall liability for substance use. Faster parent LHS predicted poorer health and lesser alcohol use, greater neuroticism and cigarette smoking, but did not predict fast LHS or overall liability for substance use among young adults. Young adult neuroticism was independent of substance use controlling for fast LHS. The surprising finding of independence between parent and child LHS casts some uncertainty upon the identity of the parent and child LHS variables. Fast LHS may be the primary driver of young adult use of common psychoactive substances. However, it is possible that the young adult fast LHS variable is better defined as young adult mating competition. We discuss our findings in depth, chart out some intriguing new directions for life history research that may clarify the dimensionality of LHS and its mediation of the intergenerational transmission of substance use, and discuss implications for substance abuse prevention and treatment.

    Individuals with a family history of substance use disorders (Family History Positive) are more likely to have early-onset substance use (i.e., prior to age 15), which may contribute to their higher rates of substance use disorders. One factor that may differentiate Family History Positive youth who engage in early-onset substance use from other Family History Positive youth is exposure to stressors. The aim of this study was to quantify how exposure to stressors from age 11-15 varies as a function of family history of substance use disorders and early-onset substance use. Self-reported stressors were prospectively compared in a sample of predominately (78.9%) Hispanic youth that included 68 Family History Positive youth (50% female) who initiated substance use by age 15 and demographically matched non-users with (n = 136; 52.9% female) and without (n = 75; 54.7% female) family histories of substance use disorders. Stressors were assessed at 6-month intervals for up to 4 years. Both the severity of stressors and the degree to which stressors were caused by an individual's own behavior were evaluated. All three groups differed from one another in overall exposure to stressors and rates of increase in stressors over time, with Family History Positive youth who engaged in early-onset substance use reporting the greatest exposure to stressors. Group differences were more pronounced for stressors caused by the participants' behavior. Family History Positive users had higher cumulative severity of stressors of this type, both overall and across time. These results indicate greater exposure to stressors among Family History Positive youth with early-onset substance use, and suggest that higher rates of behavior-dependent stressors may be particularly related to early-onset use.

    This study aimed to evaluate the association between substance use (alcohol, tobacco, and illicit drugs) and family problems among 965 adolescents from 50 public schools in two cities in São Paulo State, Brazil, in 2007. The Drug Use Screening Inventory (DUSI) was used for data collection. Use of alcohol, tobacco, and illicit drugs was associated with a negative assessment of the family relationship, lack of monitoring/support, and psychoactive substance use by family members (p illicit drugs had more family problems than those who did not consume any substance (p illicit drugs (p illicit drug use.

    2014-03-01

    Licit and illicit substance use during pregnancy is a major public health concern. Alcohol and substance (tobacco, cannabis, cocaine...) use prevalence during pregnancy remains under estimated. Some studies have reported the prevalence of alcohol or substance use in different countries worldwide but most of them were based on the mother's interview. Consumption of one or more psychoactive substances during pregnancy may have serious consequences on the pregnancy and on the child development. However, the type of consequences is still a matter of controversies. The reasons are diverse: different rating scales, potential interactions with environmental and genetic factors. Considering the negative consequences of drug use during pregnancy, preventive campaigns against the use of drugs during pregnancy are strongly recommended.

  16. Peer substance use as a mediator between early pubertal timing and adolescent substance use: longitudinal associations and moderating effect of maltreatment.

    Negriff, Sonya; Trickett, Penelope K

    2012-11-01

    Early pubertal timing has received considerable empirical support as a risk for adolescent substance use. However, few studies have examined the mediators linking these variables. Therefore, the aims of this study were (1) to examine peer substance use as a mediator between pubertal timing and adolescent substance use longitudinally and (2) to test gender and maltreatment experience as moderators of the mediational model. Data were obtained from time 1, 2, and 3 of a longitudinal study of maltreatment and development. At time 1 the sample was comprised of 303 maltreated and 151 comparison children aged 9-13 years (213 females and 241 males). Longitudinal mediation was tested using structural equation modeling and moderating effects were tested using multiple group analysis. Peer substance use mediated the relationship between early pubertal timing and later adolescent substance use for the total sample. Moderation analyses indicated this significant indirect effect did not differ for males and females. However, it did differ for maltreated versus comparison adolescents with the mediational effect only remaining significant for the comparison group. This is one of the first studies to examine peer substance use as a mediator of pubertal timing and adolescent substance use using a longitudinal design. Early maturing males are at equal risk to early maturing females for interacting with peers that may draw them into substance use. Additionally, the findings indicate that while peers are mediators for comparison adolescents a different mechanism may link early puberty to substance use for maltreated adolescents.

    1998-01-01

    A structured interview and standardized rating scales were used to assess a sample of 194 outpatients with schizophrenia in a regional Australian mental health service for substance use, abuse, and dependence. Case manager assessments and urine drug screens were also used to determine substance use. Additional measurements included demographic information, history of criminal charges, symptom self-reports, personal hopefulness, and social support. The sample was predominantly male and showed relative instability in accommodations, and almost half had a history of criminal offenses, most frequently drug or alcohol related. The 6-month and lifetime prevalence of substance abuse or dependence was 26.8 and 59.8 percent, respectively, with alcohol, cannabis, and amphetamines being the most commonly abused substances. Current users of alcohol comprised 77.3 percent and current users of other nonprescribed substances (excluding tobacco and caffeine) comprised 29.9 percent of the sample. Rates of tobacco and caffeine consumption were high. There was a moderate degree of concordance between case manager determinations of a substance-use problem and research diagnoses. Subjects with current or lifetime diagnoses of substance abuse/dependence were predominantly young, single males with higher rates of criminal charges; however, there was no evidence of increased rates of suicide attempts, hospital admissions, or daily doses of antipsychotic drugs in these groups compared with subjects with no past or current diagnosis of substance abuse or dependence. Subjects with a current diagnosis of substance use were younger at first treatment and currently more symptomatic than those with no past or current substance use diagnosis. The picture emerging from this study replicates the high rate of substance abuse in persons with schizophrenia reported in North American studies but differs from the latter in finding a slightly different pattern of substances abused (i.e., absence of

    Early administration of antibiotics for sepsis, and of fluid boluses and vasoactive agents for septic shock, is recommended. Evidence for this in children is limited. The Alberta Sepsis Network prospectively enrolled eligible children admitted to the Pediatric Intensive Care Unit (PICU) with sepsis from 04/2012-10/2014. Demographics, severity of illness, and outcomes variables were prospectively entered into the ASN database after deferred consent. Timing of interventions were determined by retrospective chart review using a study manual and case-report-form. We aimed to determine the association of intervention timing and outcome in children with sepsis. Univariate (t-test and Fisher's Exact) and multiple linear regression statistics evaluated predictors of outcomes of PICU length of stay (LOS) and ventilation days. Seventy-nine children, age median 60 (IQR 22-133) months, 40 (51%) female, 39 (49%) with severe underlying co-morbidity, 44 (56%) with septic shock, and median PRISM-III 10.5 [IQR 6.0-17.0] were enrolled. Most patients presented in an ED: 36 (46%) at an outlying hospital ED, and 21 (27%) at the Children's Hospital ED. Most infections were pneumonia with/without empyema (42, 53%), meningitis (11, 14%), or bacteremia (10, 13%). The time from presentation to acceptable antibiotic administration was a median of 115.0 [IQR 59.0-323.0] minutes; 20 (25%) of patients received their antibiotics in the first hour from presentation. Independent predictors of PICU LOS were PRISM-III, and severe underlying co-morbidity, but not time to antibiotics. In the septic shock subgroup, the volume of fluid boluses given in the first 2 hours was independently associated with longer PICU LOS (effect size 0.22 days; 95% CI 0.5, 0.38; per ml/kg). Independent predictors of ventilator days were PRISM-III score and severe underlying co-morbidity. In the septic shock subgroup, volume of fluid boluses in the first 2 hours was independently associated with more ventilator days

    2011-09-01

    Media effects research provides evidence for a link between adolescent exposure to media portrayals of substance use and usage. Exposure to media content that glamorizes and normalizes substance use carries potential public health risks. Though substance use has been examined in other media, such as film, television, and magazines, no research to date examines usage portrayals in adolescent novels. Given that adolescents do read, and given the potential impact of content on adolescent attitudes and behavior, this study provides a detailed analysis of the frequency and nature of substance use in the understudied area of novels. Substance use was examined in 40 best-selling adolescent novels on the New York Times Best Sellers list (time span June-July 2008). Substance use varied widely. Of the various types of substances, alcohol portrayals were most common. Almost all substance use was portrayed as having no consequences. Alcohol use was portrayed in similar frequencies in books aimed at younger, middle, and older adolescents, though illegal drug use was more likely to be found in books aimed at older ages. Our results suggest that the manner in which substance use is generally portrayed may encourage use among adolescents. Researchers, parents, and adolescents are encouraged to examine books as one potentially overlooked area of influence.

    2014-07-01

    We studied vasoactive and radioprotective properties of new original N-acyl, S-alkyl isothiourea derivatives which are potent inhibitors of nitric oxide synthases (preferably eNOS and iNOS). These compounds have a moderate toxicity (LD50 - 400-550 mg/kg), and are stable in aqueous solutions. In hemodynamic studies, these compounds exhibited high vasotropic activity. The use of these compounds in doses of 5-15 mg/kg (0,01-0,03 LD{sub 50}) in the experimental animals in a state of the severe hemorrhagic or endo-toxic shock causes a potent vasopressor effect, accompanied by a significant and continuous rise in blood pressure. The increasing of vascular tone developed over 2-5 min after injection and persisted for at least 60-90 minutes, excelling at least 3-5 times the duration of α1-adreno-mimetic vasopressor action. The rapid increase in vascular tone under the influence of these compounds in normo-tonic animals caused protective baroreflex to prevent high blood pressure. At doses of 10-15 mg/kg the reflex reaction was mild, but at higher doses (30-40 mg/kg) the reaction was fierce and prolonged, and was accompanied by severe bradycardia, decreasing of the cardiac output and a significant weakening of the peripheral blood flow. In all cases, the hemodynamic response was reflexive and easily eliminated by atropine. The ability of these compounds to induce circulatory hypoxia was the basis for the study of their radioprotective properties. The study of radioprotective effect on the survival of animals exposed to lethal doses of γ-radiation (10 Gy) and on the survival of hematopoietic clonogenic cells showed that these compounds in doses of 80-150 mg/kg (0,2-0,3 LD50) have considerable radioprotective action, which is comparable with the protective effect of the maximum tolerated dose of cystamine. The factor of change in dose for γ-radiation, estimated by the LD{sub 50}, was 1,42-1,58. We also investigated the ability of the test compounds, due to their hypoxic

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The emergence of risky behavior is characteristic in adolescence. Of all forms of risky behavior in adolescence, the use of psychoactive substances - cigarettes, alcohol and illegal psychoactive substances particularly stand out, because of the frequency and degree of prevalence of use, and because of the impact that they have on youth development in this sensitive stage of growing up. Unfortunately, today we are witnessing the fact that such behavior in adolescents has gained an increasingly epidemic character mainly due to the characteristics of the social context in which young people are growing up. The main objective of this research, conducted in the framework of the doctoral dissertation of the author, was determining relations between relevant sociodemographic factors: gender, age, school success, financial status and place of residence of respondents, with the appearance and intensity of use of three types of psychoactive substances - cigarettes, alcohol and illegal psychoactive substances among the general population of adolescents. The sample represents non-clinical young population, and it consists of 529 adolescents, students of the 2nd and 4th class of secondary school (17 and 18 years old. The data was collected by using Scale use of PAS (psychoactive substances in adolescents, which was designed for the purpose of this research, as well as using a set of questions intended for the registration of socio-demographic variables. Respondents filled in questionnaires in groups, during the school lessons. The data show a relationship between the three studied socio-demographic variables with the occurrence and degree of use of psychoactive substances in the adolescence period, such as gender, age and school success of the respondents. As regards gender of respondents associated with the occurrence and degree of alcohol and illegal substance use in adolescents, male adolescents more likely use alcohol and illegal psychoactive substances

  16. Association Between Substance Use and Gun-Related Behaviors.

    Chen, Danhong; Wu, Li-Tzy

    2016-01-01

    Gun-related violence is a public health concern. This study synthesizes findings on associations between substance use and gun-related behaviors. Searches through PubMed, Embase, and PsycINFO located 66 studies published in English between 1992 and 2014. Most studies found a significant bivariate association between substance use and increased odds of gun-related behaviors. However, their association after adjustment was mixed, which could be attributed to a number of factors such as variations in definitions of substance use and gun activity, study design, sample demographics, and the specific covariates considered. Fewer studies identified a significant association between substance use and gun access/possession than other gun activities. The significant association between nonsubstance covariates (e.g., demographic covariates and other behavioral risk factors) and gun-related behaviors might have moderated the association between substance use and gun activities. Particularly, the strength of association between substance use and gun activities tended to reduce appreciably or to become nonsignificant after adjustment for mental disorders. Some studies indicated a positive association between the frequency of substance use and the odds of engaging in gun-related behaviors. Overall, the results suggest a need to consider substance use in research and prevention programs for gun-related violence. © The Author 2016.

    Whether a doctor, professional baseball manager, or a politician, having successful negotiation skills is a critical part of being a leader. Building upon prior journal articles on negotiation strategy, the author presents the concept of the multiple equivalent simultaneous offer (MESO). The concept of a MESO is straightforward: as opposed to making a single offer, make multiple offers with several variables. Each offer alters the different variables, such that the end result of each offer is equivalent from the perspective of the party making the offer. Research has found several advantages to the use of MESOs. For example, using MESOs, an offer was more likely to be accepted, and the counterparty was more likely to be satisfied with the negotiated deal. Additional benefits have been documented as well, underscoring why a prepared radiology business leader should understand the theory and practice of MESO.

    1980-05-01

    The amount of data available concerning the toxicity of various substances to freshwater biota is so large that it is difficult to use in a practical situation, such as environmental impact assessment. In this document, summary tables are presented showing acute and/or chronic toxicity of selected substances for various groups of aquatic biota. Each entry is referenced to its original source so that details concerning experimental conditions may be consulted. In addition, general information concerning factors modifying toxicity, synergisms, evidence of bioaccumulation, and water quality standards and criteria for the selected substances is given. The final table is a general toxicity table designed to provide an easily accessible and general indication of toxicity of selected substances in aquatic systems.

    To determine the prevalence of substance use in adolescents with eating disorders, compare the results with a data set of Ontario high school students, and explore why adolescents with eating disorders do, or do not, use various substances. From January 1999 to March 2000, 101 female adolescents who met the DSM-IV criteria for an eating disorder were followed up in a tertiary care pediatric treatment center. They were asked to participate in a cross-sectional study using a self-administered questionnaire assessing substance use and investigating reasons for use and nonuse; 95 agreed to participate and 77 completed the questionnaire (mean age, 15.2 years). The patients were divided into two groups: 63 with restrictive symptoms only, 17 with purging symptoms. The rates of drug use between subjects and their comparison groups were compared by z-scores, with the level of significance set at.05. During the preceding year, restrictors used significantly less tobacco, alcohol, and cannabis than grade- and sex-matched comparison populations, and purgers used these substances at rates similar to those of comparison subjects. Other drugs seen frequently in the purgers included hallucinogens, tranquilizers, stimulants, LSD, PCP, cocaine, and "ecstasy." Both groups used caffeine and laxatives, but few used diet pills. Restrictors said they did not use substances because they were bad for their health, tasted unpleasant, were contrary to their beliefs, and were too expensive. Purgers generally used substances to relax, relieve anger, avoid eating, and "get away" from problems. Female adolescents with eating disorders who have restrictive symptoms use substances less frequently than the general adolescent population but do not abstain from their use. Those with purging symptoms use substances with a similar frequency to that found in the general adolescent population. Because the sample size for the purging group was small, firm conclusions cannot be drawn from our analysis

    1979-01-01

    Using immunohistochemical techniques we studied duodenal biopsies from 18 patients with coeliac disease and 24 patients with normal duodenal morphology. We had access to antisera against the following gastrointestinal peptides: cholecystokinin (CCK), gastric inhibitory peptide (GIP), gastrin-17, glucagon-enteroglucagon, motilin, neurotensin, pancreatic peptide (PP), secretin, somatostatin, substance P and vasoactive intestinal peptide (VIP). The somatostatin, GIP, CCK, and glucagon cells were increased in number in coeliac disease. The number of motilin cells was slightly increased, while secretin cells were reduced. Cells storing gastrin-17, substance P, or neurotensin were rare in all patients regardless of diagnosis. No PP immunoreactive cells were found and VIP was localised to neurons only. In biopsies from patients having a mucosa with ridging of villi the number of the various endocrine cell types did not differ from that in the control group. Images Fig. 2 PMID:385455

    Full Text Available Background. Youth populations are vulnerable to substance use particularly in developing countries where circumstances may be favorable for it. There is no published data on substance use among the youth in Sudan other than on tobacco use. Objectives. The aim of this study was to investigate the prevalence, circumstances, and factors associated with substance use. Methods. An institution-based survey was conducted on a sample of 500 students. Data was collected using a questionnaire designed by the WHO for student drug surveys and analyzed using IBM SPSS version 20. Results. The overall prevalence of substance use is 31%. The current prevalence of tobacco, cannabis, alcohol, amphetamines, tranquilizers, inhalants, opiates, cocaine, and heroin use was 13.7%, 4.9%, 2.7%, 2.4%, 3.2%, 1%, 1.2%, 0.7%, and 0.5%, respectively. Curiosity (33.1% was the main reason for initiation of substance use. The main adverse effects reported were health problems (19.7% and theft (19.7%. Peers (40.9% were the prime source of substance use. On multivariate analysis, male sex was the principle predictor for substance use (AOR: 5.55; 95% CI: 3.38, 9.17. Conclusion. Strategies to control substance use should encompass the role of the university and parents in observing and providing education to improve awareness of substances and their consequences.

    The subject of the research was the analysis of frequency and type of psychoactive substances used, basing on the determinations the blood and/or urine samples, performed in the toxicological laboratory of the Department of Clinical and Industrial Toxicology Jagiellonian University in Kraków in the period from December 2001 to November 2003. From 17,649 performed determinations--45.5% were positive. 50% of the positive determinations were psychoactive substances. The most often psychoactive substance determined was ethyl alcohol (52.86%), next benzodiazepines (17.41%), amphetamines (10.54%), opiates (8.05%), THC (6.87%), barbiturates (3.74%), and occasionally atropine and cocaine. There was observed a variety of mixed, simultaneously taking psychoactive substances, especially ethyl alcohol, opiates, amphetamine derivatives and cannabinoids. The analysis of the occurrence of psychoactive substances in biological samples from patients treated in different hospital departments, others hospitals and ordered by private persons also was performed. In the last two years 369 private patients ordered psychoactive substances determinations and 78 of them were positive.

    1989-01-01

    Use of nonprescribed mood altering substances is pervasive and problematic in young adults with serious mental illnesses in community care. Fifty-eight percent of young adult clients with clearly defined schizophrenia or schizophrenia-related disorders participating in a long-term community treatment study were rated by staff or themselves as using alcohol, cannabis, or other street drugs several times a week or more. We interviewed in depth a random sample of these "significant users" to obtain their perspective on their frequencies, patterns, histories, contributing factors to, and effects of substance use and their related treatment experiences. Results revealed these clients' substance use to be of long duration and deeply entrenched, with current use often involving multiple substances including both street drugs and substances of "everyday life" (e.g., caffeine, nicotine). Clients reported compelling reasons for use including anxiety reduction, relief of boredom, and a means for social contact. Staff and clients clearly view substance use quite differently, with the latter focusing at least as much on consequences of symptom relief as symptom exacerbation. Treatment implications are discussed.

    Full Text Available Substance abuse and dependence among the employed have massive cost implications for South Africa. Employers are legally obliged to provide opportunities for the treatment of substance dependence before dismissal is considered. Problem areas are the following: inadequate identification of employees with substance-abuse problems, infrequent treatment referrals, and overlooking of substance abuse in the workplace. This article attempts to address these issues by providing an overview of literature dealing with the problem of substance abuse and dependence in the workplace. Addressing this problem calls for specialist intervention measures, which are discussed in the article.

    Although categorized as an impulse control disorder, kleptomania has many features in common with substance use disorders. This paper sought to examine the mounting evidence supporting the phenomenological, clinical, epidemiological, and biological links between kleptomania and substance addictions. A review of the literature examining family history, genetics, comorbid psychiatric conditions, neuroimaging, and phenomenology was utilized to examine the relationship of kleptomania to substance addiction. Kleptomania and substance addiction share common core qualities, including similar treatment successes, as well as etiologic and phenomenological similarities. Future research investigating the relationship between kleptomania and substance use disorders holds significant promise in advancing prevention and treatment strategies for addiction in general. Research investigating kleptomania (and other behavioral addictions) and its relationship to substance addiction holds significant promise in advancing prevention and treatment strategies for addiction in general.

    2004-01-01

    The paper reviews the responsibilities of producers, importers and distributors set in a new Act of January 2001 on chemical substances and preparations (Off. J. 2001, No. 11, item 84, with subsequent amendments). This Act together with executive provisions is aimed at harmonizing Polish legislation with EU requirements. The Act sets conditions, restriction and bans of production placing on the market and use of chemical substances and preparations in order to protect human health and environment against their harmful effects. The Act together with a number of executive provisions render those who introduce dangerous chemicals and chemical preparations, including distributors responsible for: classification and labelling of dangerous chemical substances and preparations; possessing, making available and up-dating safety data sheets; supplying packages containing certain dangerous substances with child-proof fastenings; notifying the Inspector for Chemical Substances and Preparations about placing a dangerous preparation on the market; notifying the Inspector about a new substance and conducting required studies; being properly qualified to handle dangerous substances. The Act strictly defines the term "placing a substance or a preparation on the market"--it means making a substance or a preparation available to third parties on the territory of The Republic of Poland, territories of the Member States of the European Union or the territory of Iceland, Liechtenstein and Norway, unless the Act provides otherwise; it also means introduction of a substance or a preparation from outside of the territory referred to above on the customs territory of The Republic of Poland, or that of the member states of the European Union and other states listed above. In addition, some of the responsibilities defined by the provisions of the law on chemical substances and preparations are also applicable to handling of biocidals, which are classified as dangerous substances.

  14. The monitoring of trade in and control of psychotropic substances to guard against their diversion.

    Science.gov (United States)

    Bayer, I

    1983-01-01

    The establishment of international control of opiates has been an important achievement of the international community; this is substantiated by the fact that, at the beginning of this century, legally manufactured morphine and heroin were the principal sources of illicit supply, whereas at present the illicit traffic in these drugs is supplied from illicit sources. The poppy straw process has helped to promote measures to control opium poppy cultivation in a number of European countries; Turkey has been a successful example of such control. The present large-scale illicit traffic in cannabis resin and cocaine is the consequence of the lack of the implementation of provisions of the Single Convention on Narcotic Drugs, 1961, to control the cannabis plant and the coca bush at the national level. The provisions of the 1971 Convention on Psychotropic Substances, being largely a result of international compromise, are not designed in the best possible way to prevent the diversion of psychotropic substances from legal sources to illicit channels. There are no appropriate provisions for the control and monitoring of international transactions. There is a discrepancy between the rather limited scope of international control of substances listed in schedules III and IV of the 1971 Convention and the much larger scope of control of hypnotics, sedatives and tranquillizers at national levels. The provisions of the 1971 Convention, however, constitute a legal basis for bilateral and multilateral actions for the detection of suspected diversion cases, and offer possibilities of promoting the prevention of diversion of psychotropic substances. At present, the relationship between the control of psychotropic drugs, including the prevention of diversion and the organization of the national drug supply system, as well as the efficacy of national control over pharmaceutical products, has not been fully recognized by the international community.

  15. The substance use risk profile scale: a scale measuring traits linked to reinforcement-specific substance use profiles.

    2009-12-01

    The Substance Use Risk Profile Scale (SURPS) is based on a model of personality risk for substance abuse in which four personality dimensions (hopelessness, anxiety sensitivity, impulsivity, and sensation seeking) are hypothesized to differentially relate to specific patterns of substance use. The current series of studies is a preliminary exploration of the psychometric properties of the SURPS in two populations (undergraduate and high school students). In study 1, an analysis of the internal structure of two versions of the SURPS shows that the abbreviated version best reflects the 4-factor structure. Concurrent, discriminant, and incremental validity of the SURPS is supported by convergent/divergent relationships between the SURPS subscales and other theoretically relevant personality and drug use criterion measures. In Study 2, the factorial structure of the SURPS is confirmed and evidence is provided for its test-retest reliability and validity with respect to measuring personality vulnerability to reinforcement-specific substance use patterns. In Study 3, the SURPS was administered in a more youthful population to test its sensitivity in identifying younger problematic drinkers. The results from the current series of studies demonstrate support for the reliability and construct validity of the SURPS, and suggest that four personality dimensions may be linked to substance-related behavior through different reinforcement processes. This brief assessment tool may have important implications for clinicians and future research.

    2017-01-01

    This paper first introduces important conceptual and practical distinctions among three key terms: substance "use," "misuse," and "disorders" (including addiction), and goes on to describe and quantify the important health and social problems associated with these terms. National survey data are presented to summarize the prevalence and varied costs associated with misuse of alcohol, illegal drugs, and prescribed medications in the United States. With this as background, the paper then describes historical views, perspectives, and efforts to deal with substance misuse problems in the United States and discusses how basic, clinical, and health service research, combined with recent changes in healthcare legislation and financing, have set the stage for a more effective, comprehensive public health approach.

    This study used mixed methods to explore youth attitudes about recovery-related needs and important drug-avoidance behaviors after treatment. Focus groups were conducted with 118 substance using youth in treatment (four residential and 10 outpatient settings) throughout Los Angeles County. The average age was 17.4 (SD = 2.9); 78.3% were male, 66.1% Latino; and most were in treatment for primary marijuana (40.9%) or methamphetamine (30.4%) abuse. Quantitatve results from the drug-avoidance activity survey identified the following factors youth rated as important to their recovery after treatment: lifestyle improvement activities (95.7%); changing personal drug behaviors (89.6%); drug environment/culture change activities (82.5%); with the least important being therapeutic activities (78.5%). Qualitative findings from focus groups that asked what youth think are important for recovery programs to address after treatment revealed the following four areas: (1) recovery promotion to developmentally appropriate activities (95%); (2) facilitating the use of coping skills to deal with stress (85%); (3) offering alternative recovery support options (not just abstinence only) (75%); and (4) continuing to provide substance use education (65%). Findings highlight essential aspects of recovery in terms of need and drug-avoidance behaviors considered important to youth in treatment. Such information will help to better address clinical and recovery support models aimed at relapse prevention to ensure that the perceived problems of substance-abusing youth are adequately met.

    Girotto, Edmarlon; Mesas, Arthur Eumann; de Andrade, Selma Maffei; Birolim, Marcela Maria

    2014-01-01

    The aim of this study was to summarise the scientific evidence on the prevalence of psychoactive substance use and on the factors associated with their intake among truck drivers. A systematic review was performed in the databases PubMed, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, and Cochrane and 36 cross-sectional studies were identified with quantitative results about the use of psychoactive substances by truck drivers. Out of these, 28 were carried out in countries with large land areas and 23 obtained their information through self-reporting. The most frequently studied substances were alcohol (n=25), amphetamines (n=17), marijuana (n=16) and cocaine (n=13). The prevalence of the use of these substances greatly varied: alcohol (0.1-91.0%); amphetamines (0.2-82.5%), marijuana (0.2-29.9%), cocaine (0.1-8.3%). The frequency of substance use was lower in studies that investigated the presence of these substances in biological samples than in those based on self-reported use. In 12 studies that evaluated factors associated with the intake of psychoactive substances, the following stood out: younger age, higher income, longer trips, alcohol consumption, driving in the night shift, travelling interstate routes, long or short sleep, fewer hours of rest, little experience of the driver, connection with small and medium sized companies, income below levels determined by labour agreements, productivity-based earnings and prior involvement in accidents. The frequency of psychoactive substance use by truck drivers seems to be high, although that greatly varies according to the type of substance and the method of collecting the information. The use of these substances was mainly associated with indicators of poor working conditions.

    To compare European students' personal use and approval of illicit substance use with their perceptions of peer behaviours and attitudes, and investigate whether perceptions of peer norms are associated with personal use of illicit substances and attitudes. This study used baseline data from the Social Norms Intervention for the prevention of Polydrug usE (SNIPE) project involving 4482 students from seven European countries in 2012. Students completed an online survey which included questions on personal and perceived peer illicit substance use and personal and perceived peer attitude towards illicit substances. 8.3% of students reported having used illicit substances at least once in their life. 49.7% of students perceived that the majority of their peers have used illicit substances more frequently than themselves. The perception was significantly associated with higher odds for personal illicit substance use (OR: 1.97, 95% CI: 1.53-2.54). The perception that the majority of peers approve illicit substance use was significantly associated with higher odds for personal approval of illicit substance use (OR: 3.47, 95% CI: 2.73-4.41). Students commonly perceived that their peers used illicit subtances more often than themselves. We found an association between the perceived peer norms/attitudes and reported individual behaviour/attitudes. Copyright © 2014 Elsevier Inc. All rights reserved.

    1993-03-01

    The aim of the present research programme is to study the complexation behaviour of actinide ions with humic substances in natural aquifer systems and hence to quantify the effect of humic substances on the actinide migration. Aquatic humic substances commonly found in all groundwaters in different concentrations have a strong tendency towards complexation with actinide ions. This is one of the major geochemical reactions but hitherto least quantified. Therefore, the effect of humic substances on the actinide migration is poorly understood. In the present research programme the complexation of actinide ions with humic substances will be described thermodynamically. This description will be based on a model being as simple as possible to allow an easy introduction of the resulting reaction constants into geochemical modelling of the actinide migration. This programme is a continuation of the activities of the COCO group in the second phase of the CEC-MIRAGE project. The programme consists of the following three main tasks: Task 1: Complexation reactions of actinide ions with well characterized reference and site-specific humic and fulvic acids; Task 2: Competition reactions with major cations in natural groundwaters; Task 3: Validation of the complexation data in natural aquatic systems by comparison of calculation with spectroscopic experiment.

Addiction treatments will continue to be offered through traditional substance abuse care systems, but these will be more integrated with primary care, and less separated as treatment facilities leverage opportunities to blend services, financing mechanisms, and health information systems under federally driven incentive programs. To further these reforms, vigilance will be needed by consumers, clinicians, and policy makers to assure that the unmet treatment needs of individuals with addiction are addressed. Embedded in this article are essential recommendations to facilitate the improvement of care for substance use disorders under health care reform. Ultimately, as addiction care acquires more of the “look and feel” of mainstream medicine, it is important to be mindful of preexisting trends in health care delivery overall that are reflected in recent health reform legislation. Within the world of addiction care, clinicians must move beyond their self-imposed “stigmatization” and sequestration of specialty addiction treatment. The problem for addiction care, as it becomes more “mainstream,” is to not comfortably feel that general slogans like “Treatment Works,” as promoted by Substance Abuse and Mental Health Services Administration’s Center for Substance Abuse Treatment during its annual Recovery Month celebrations, will meet the expectations of stakeholders outside the specialty addiction treatment community. Rather, the problem is to show exactly how addiction treatment works, and to what extent it works-there have to be metrics showing changes in symptom level or functional outcome, changes in health care utilization, improvements in workplace attendance and

    Full Text Available Numerous studies have supported a role for oxidative stress in the development of ischemic damage and endothelial dysfunction. Crataegus oxyacantha (Co and Rosmarinus officinalis (Ro extracts are polyphenolic-rich compounds that have proven to be efficient in the treatment of cardiovascular diseases. We studied the effect of extracts from Co and Ro on the myocardial damage associated with the oxidative status and to the production of different vasoactive agents. Rats were assigned to the following groups: (a sham; (b vehicle-treated myocardial infarction (MI (MI-V; (c Ro extract-treated myocardial infarction (MI-Ro; (d Co extract-treated myocardial infarction (MI-Co; or (e Ro+Co-treated myocardial infarction (MI-Ro+Co. Ro and Co treatments increased total antioxidant capacity, the expression of superoxide dismutase (SOD-Cu2+/Zn2+, SOD-Mn2+, and catalase, with the subsequent decline of malondialdehyde and 8-hydroxy-2′-deoxyguanosine levels. The extracts diminished vasoconstrictor peptide levels (angiotensin II and endothelin-1, increased vasodilators agents (angiotensin 1–7 and bradikinin and improved nitric oxide metabolism. Polyphenol treatment restored the left intraventricular pressure and cardiac mechanical work. We conclude that Ro and Co treatment attenuate morphological and functional ischemic-related changes by both an oxidant load reduction and improvement of the balance between vasoconstrictors and vasodilators.

    The aim of this study was to explore in detail the relationship between various social aspects of young people's lives and substance use and differences in the degree of influence exerted by the different social factors as a function of age. Design, setting, participants. The study was a survey of pupils aged 11-16 in a stratified sample of five English schools. Data from 4516 participants were obtained in relation to their cigarette, alcohol and illicit drug use and their contact with the police, perceived academic achievements and future expectations, religious beliefs, family structure, the importance of family versus peer opinions and suspension from school. Cumulative, age-specific preferences of substance misuse were compared. Logistic regression was used to rank the various risk factors. Substantial differences were found between substance users and non-users and the various risk factors being examined. For example, of those who had only been in trouble with the police, 18.8% used illegal drugs compared with 1.6% of those who had not had a police contact and who had no other risk factors. Many of these relationships were age-sensitive. For instance, the negative relationship between belief in God and illicit drug use became stronger as age increased (non-believers: y = 8.1886x - 9.16 R(2) = 0.9484; believers: y = 5.1514x - 8.08 R(2) = 0.9247). These results suggest that, within this sample of English adolescents, there was a strong relationship between substance use and the social factors examined. Although there were differences depending upon whether cigarette, alcohol or illicit drug use was being modelled, logistic regression indicated that the social factors could be ranked in the following order of importance: concurrent use of the second and third substances, having been in trouble with the police, perceived poor academic performance and low future academic expectations, a lack of religious belief, coming from a non-intact family, favouring peer over

    Screening adolescents for substance use and intervening immediately can reduce the burden of addiction and substance-related morbidity. Several screening tools have been developed to identify problem substance use for adolescents, but none have been calibrated to triage adolescents into clinically relevant risk categories to guide interventions. To describe the psychometric properties of an electronic screen and brief assessment tool that triages adolescents into 4 actionable categories regarding their experience with nontobacco substance use. Adolescent patients (age range, 12-17 years) arriving for routine medical care at 2 outpatient primary care centers and 1 outpatient center for substance use treatment at a pediatric hospital completed an electronic screening tool from June 1, 2012, through March 31, 2013, that consisted of a question on the frequency of using 8 types of drugs in the past year (Screening to Brief Intervention). Additional questions assessed severity of any past-year substance use. Patients completed a structured diagnostic interview (Composite International Diagnostic Interview-Substance Abuse Module), yielding Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) substance use diagnoses. For the entire screen and the Screening to Brief Intervention, sensitivity and specificity for identifying nontobacco substance use, substance use disorders, severe substance use disorders, and tobacco dependence were calculated using the Composite International Diagnostic Interview-Substance Abuse Module as the criterion standard. Of 340 patients invited to participate, 216 (63.5%) enrolled in the study. Sensitivity and specificity were 100% and 84% (95% CI, 76%-89%) for identifying nontobacco substance use, 90% (95% CI, 77%-96%) and 94% (95% CI, 89%-96%) for substance use disorders, 100% and 94% (95% CI, 90%-96%) for severe substance use disorders, and 75% (95% CI, 52%-89%) and 98% (95% CI, 95%-100%) for nicotine dependence.

    Organ offers in liver transplantation are high-risk medical decisions with a low certainty of whether a better liver offer will come along before death. We hypothesized that decision support could improve the decision to accept or decline. With data from the Scientific Registry of Transplant Recipients, survival models were constructed for 42,857 waiting-list patients and 28,653 posttransplant patients from 2002 to 2008. Daily covariate-adjusted survival probabilities from these 2 models were combined into a 5-year area under the curve to create an individualized prediction of whether an organ offer should be accepted for a given patient. Among 650,832 organ offers from 2008 to 2013, patient survival was compared by whether the clinical decision was concordant or discordant with model predictions. The acceptance benefit (AB)--the predicted gain or loss of life by accepting a given organ versus waiting for the next organ--ranged from 3 to -22 years (harm) and varied geographically; for example, the average benefit of accepting a donation after cardiac death organ ranged from 0.47 to -0.71 years by donation service area. Among organ offers, even when AB was >1 year, the offer was only accepted 10% of the time. Patient survival from the time of the organ offer was better if the model recommendations and the clinical decision were concordant: for offers with AB > 0, the 3-year survival was 80% if the offer was accepted and 66% if it was declined (P decision support may improve patient survival in liver transplantation. © 2015 American Association for the Study of Liver Diseases.

    Full Text Available Abstract Background This study was conducted to examine the perception and views of medical students regarding the extent of alcohol and substance abuse in the community and the possible predisposing factors for this problem. Methods It is a cross-sectional study involving samples from two medical colleges in Riyadh, Saudi Arabia. The students who decided to participate in the study without the offer of any incentives filled an anonymous, self administered questionnaire which had been designed to meet the purpose of the study. Results Two hundred and fifteen out of three hundred and thirty students (65% response rate participated in this study. About 75% of them believe that alcohol and substance abuse is a common problem in the community. Students' views also correspond with the reported view that the problem is mainly present in young adult males. Married males and senior students perceived the problem as more serious than their other colleagues. Students perceived that alcohol was the most commonly abused drug in the community, followed by amphetamines, heroin, cannabis and cocaine. They believe that influence of friends, life stressors, tobacco smoking and curiosity are the most important predisposing factors for abuse of alcohol and other substances. According to the students' perception, the main beneficial effect of alcohol and substance abuse was stress alleviation. About 3% of the students have also indicated that they may use alcohol or some other substance in the future. Conclusion Despite scarce information on the subject and a strong religious belief in Saudi Arabia against the use of alcohol and other addictive substances, a significant majority of the medical students in Riyadh, the capital of Saudi Arabia, perceived that alcohol and substance abuse is a common problem in the community. Some students appear to perceive the seriousness of the problem less than others. Efforts are needed to educate young men and women at an early

    The presence of naturally occurring complexing agents that may enhance the migration of disposed radionuclikes and thus facilitate their uptake by plantsis a problem associated with the underground disposal of radioactive wastes in bedrock. The main purpose of this work is to characterized humic substances from ground water and compare them with humic substances from surface water. The humic materials isolated from ground waters of a borehole in Fjaellveden (Sweden) were characterized by elemental and functional group analyses. Spectroscopic properties, molecular weight distributions as well as acid-base properties of the fulvic and humic fractions were also studied. The ground water humic substances were found to be quite similar in many respects (but not identical) to the Swedish surface water humics concentrated from the Goeta River but appeared to be quite different from the American ground water humics from Biscayne Florida Aquifer or Laramie Fox-Hills in Colorado. The physico-chemical properties of the isolated humic materials are discussed

  2. EMOTIONALLY AVOIDANT LANGUAGE IN THE PARENTING INTERVIEWS OF SUBSTANCE-DEPENDENT MOTHERS: ASSOCIATIONS WITH REFLECTIVE FUNCTIONING, RECENT SUBSTANCE USE, AND PARENTING BEHAVIOR

    2012-01-01

    Parenting and emotion regulation are two known, and potentially interrelated, areas of impairment among substance-abusing mothers. In this study, we examine substance -abusing mothers’ (positive and negative) emotion language word use during their discussion of negative parenting experiences on the Parent Development Interview for its association with reflective functioning (RF), recent substance-use history, and sensitivity to child cues. Within a sample of 47 methadone-maintained mothers, we evaluate the hypothesis that linguistic evidence of emotional avoidance (more frequent positive feeling words and less frequent negative emotion words) will be associated with lower RF, more recent substance use, and more insensitive parenting. Further, we evaluate whether language use mediates the association between self-focused RF and insensitive parenting. Results of hierarchical regressions suggest that more frequent positive feeling word use, but not negative emotion word use, is associated with lower RF, more recent substance use, and lower sensitivity to child cues. Positive feeling word use partially mediates the association between self-focused RF and insensitive parenting. Results are discussed in the context of their contribution to the literature on emotion and parenting in substance-abusing populations. PMID:23049148

    The current study examined the relationship between substance use references contained in music lyrics and videos and the attitudes and behaviors regarding substance use of White non-Hispanic, African American, and Hispanic emerging adults from a cultivation and social norms framework by assessing 425 male and female college students. It was hypothesized that there would be ethnic variations in perceived harm from substance use and reported recent substance use and that exposure to substance use references contained in music could mediate this relationship. Results confirmed ethnic differences in perceived risk associated with substance use as well as reported substance use with White non-Hispanic college students reporting the least perceived risk and the most substance use. African American college students reported the most perceived risk associated with substance use and the least amount of reported substance use. Results of the Test of Joint Significance confirmed the mediational model in that participant ethnicity was associated with exposure to substance use references in music lyrics and music videos. Substance use references in music lyrics, then, was able to predict actual reported substance use of participants but not perceived risk associated with substance use.

  5. Beyond Drug Use: A Systematic Consideration of Other Outcomes in Evaluations of Treatments for Substance Use Disorders

    Across the addictions field, the primary outcome in treatment research has been reduction in drug consumption. A comprehensive view of the impact of substance use disorders on human functioning suggests that effective treatments should address the many consequences and features of addiction beyond drug use, a recommendation forwarded by multiple expert panels and review articles. Despite recurring proposals, and a compelling general rationale for moving beyond drug use as the sole standard for evaluating addiction treatment, the field has yet to adopt any core set of “other” measures that are routinely incorporated into treatment research. Among the many reasons for the limited impact of previous proposals has been the absence of a clear set of guidelines for selecting candidate outcomes. This paper is the result of the deliberations of a panel of substance abuse treatment and research experts convened by the National Institute on Drug Abuse to discuss appropriate outcome measures for clinical trials of substance abuse treatments. This paper provides an overview of previous recommendations and outlines specific guidelines for consideration of candidate outcomes. A list of outcomes meeting those guidelines is described and illustrated in detail with two outcomes: craving and quality of life. The paper concludes with specific recommendations for moving beyond the outcome listing offered in this paper to promote the programmatic incorporation of these outcomes into treatment research.

    Several researchers have investigated substance use patterns using a latent class analysis; however, hardly no studies exist on substance use patterns across countries. Adolescent substance use patterns, demographic factors, and international differences in the prevalence of substance use patterns were explored. Data from 25 European countries were used to identify patterns of adolescent (12-16 years, 50.6% female) substance use (N = 33,566). Latent class analysis revealed four substance use classes: nonusers (68%), low-alcohol users (recent use of beer, wine, and alcopops; 16.1%), alcohol users (recent use of alcohol and lifetime use of marijuana; 11.2%), and polysubstance users (recent use of alcohol, marijuana, and other illicit drugs; 4.7%). Results support a general pattern of adolescent substance use across all countries; however, the prevalence rates of use patterns vary for each country. The present research provides insight into substance use patterns across Europe by using a large international adolescent sample, multidimensional indicators and a variety of substances. Substance use patterns are helpful when targeting policy and prevention strategies.

    The dentin-pulp complex is a peripheral end-organ supplied by dense sensory nerve fibers. Substance P, a representative neuropeptide widely distributed in the dental pulp, has been reported to play roles in pain transmission and the amplification of inflammation. We analyzed here the expression of the neurokinin 1 (NK1) receptor, preferentially activated by substance P, using immunocytochemistry in rat dental pulp at both the light and electron microscopic levels. Conspicuous NK1 receptor immunoreactivity was found in the odontoblasts; immunolabelings were present at their plasma membrane and endosomal structures, especially in their cytoplasmic processes. Immunoreactions for NK1 receptor were also detectable in a part of the nerve terminals associated with the cytoplasmic processes of the odontoblasts. Furthermore, the endothelial cells of capillaries and post-capillary venules and the fibroblasts were labeled with the NK1 receptor in the subodontoblast layer. These findings suggest that pulpal cells and nerve fibers are targets for substance P that mediate multiple functions, including a vasoactive function and the regulation of vascular permeability as well as the modulation of pain transmission.

    2004-05-01

    The introduction into the Baltic Sea of hazardous substances that are persistent, bioaccumulate, and are toxic is an important environmental and human health problem. Multilateral efforts to address this problem have primarily been taken under the Helsinki Commission (HELCOM). This article examines past HELCOM efforts on hazardous substances, and discusses future challenges regarding their management. The article finds that past actions on hazardous substances have had a positive effect on improving Baltic environmental quality and reducing human health risks, although there are remaining issues and difficulties that need to be addressed. In particular, four related future challenges for HELCOM management of hazardous substances are identified and discussed: i) the need to engender further implementation and building public and private sector capacities; ii) the need to improve data availability, quality and comparability across the region and international fora; iii) the need to strengthen existing regulations and incorporate new issues; and iv) the need to effectively coordinate HELCOM activities with efforts on hazardous substances in other international fora.

    2007-09-22

    The ultimatum game is a simple negotiation with the interesting property that people frequently reject offers of 'free' money. These rejections contradict the standard view of economic rationality. This divergence between economic theory and human behaviour is important and has no broadly accepted cause. This study examines the relationship between ultimatum game rejections and testosterone. In a variety of species, testosterone is associated with male seeking dominance. If low ultimatum game offers are interpreted as challenges, then high-testosterone men may be more likely to reject such offers. In this experiment, men who reject low offers ($5 out of $40) have significantly higher testosterone levels than those who accept. In addition, high testosterone levels are associated with higher ultimatum game offers, but this second finding is not statistically significant.

  11. Organic substances in ashes; Organiska aemnen i askor

    Energy Technology Data Exchange (ETDEWEB)

    Bjurstroem, Henrik [AaF-Process AB, Stockholm (Sweden)

    2006-12-15

    Based on a review of available literature the following conclusions have been reached: Organic substances constitute a minor part of the TOC, Total Organic Carbon, and inert, elemental carbon constitutes the major part, TOC being expressed as weight percent of the ash. Organic substances are trace substances, with concentrations of the order a few mg/kg, exceptionally g/kg, in screening analyses, and of the order of ng/kg to mg/kg in dedicated analyses. The results from a screening of organic content depend largely on sample preparation and the method of analysis. The substances that are commonly identified are aliphatic acids and n-alkanes (semi-volatile substances). However, in one investigation chlorinated hydrocarbons such as trichloroethylene were found instead, which are more volatile than acids and n-alkanes In the leachates, organic substances are mostly humus-like relatively high molecular products of degradation. There is not any experimental evidence for substances to be terminated, which evidence would allow an assessment of their importance. The concentrations of dioxins and furans in all ashes seem to be low, from a few ng/kg TEQ ta few tens of ng/kg TEQ. Their concentration in bioashes is significantly lower than the default value in UNEP's guidelines for national inventories of sources of dioxins. The exception is air pollution control residues from waste incineration, which residues contain 200 - 2,000 ng/kg TEQ depending on the type of plant. If combustion residues from waste incineration are well investigated, residues from other fuels are not. The concentration of PAH varies more widely and is more uncertain, from 0.015 mg/kg DS ta few hundreds of mg/kg DS. It is not feasible tassess the consequences for the environment of the presence of organic substances in ashes in this survey. This demands a separate study.

    During the last years, an increased misuse of doping substances in sport has been observed. The action of doping substances characterized by the stimulation of blood flow and metabolic processes is also reflected in the hair structure. In the present study it was demonstrated that optical coherent tomography is well suited for the analysis of hair parameters influenced by doping. Analyzing 20 patients, systemically treated with steroids which also represent doping substances, it was found that in all cases a significant increase in the cross-section of the hairs could be detected. The results obtained in the study are not only important for the screening of doping substances but also for medical diagnostics and control of compliance of patients.

    Patto, R J; Vinayek, R; Jensen, R T; Gardner, J D

    1992-01-01

    In a previous study, we found that first incubating guinea pig pancreatic acini with carbachol caused desensitization of the enzyme secretory response to cholecystokinin-octapeptide (CCK-8), bombesin, and carbachol but not that to substance P. This carbachol-induced desensitization could be accounted for by carbachol-induced down-regulation of receptors for CCK-8, bombesin, and carbachol. Although carbachol did not desensitize the enzyme secretory response to substance P, an effect of carbachol on substance P receptors was not examined. In the present study, in dispersed acini from guinea pig pancreas, substance P caused a twofold increase in amylase secretion. Stimulation was half-maximal at 0.7 nM and was maximal at 10 nM. Analysis of the ability of substance P to inhibit binding of 125I-substance P to substance P receptors indicated that acini possess a single class of receptors for substance P (Kd = 0.8 +/- 0.1 nM; Bmax = 1,037 +/- 145 fmol/mg of DNA). There was a close correlation between the relative potency with which substance P stimulated amylase secretion (0.7 nM) and the potency for inhibiting binding of 125I-substance P (Kd = 0.8 nM). First incubating pancreatic acini with carbachol did not alter either substance P-stimulated enzyme secretion or binding of 125I-substance P to substance P receptors, whereas in the same experiments, carbachol reduced binding of 125I-CCK-8 to cholecystokinin receptors by 50% and decreased in CCK-8-stimulated enzyme secretion by 50%.(ABSTRACT TRUNCATED AT 250 WORDS)

    2015-08-01

    Due to the Affordable Care Act and other recent laws and regulations, funding for substance use disorder (SUD) treatment is on the rise. In the 2000s, the Veterans Health Administration (VA) implemented several initiatives that increased funding for SUD treatment during a period of growth in demand for it. A key question is whether access to and intensity of treatment kept pace or declined. Using VA SUD treatment funding data and patient-level records to construct performance measures, we studied the relationship between funding and access during the VA expansion. Overall, we observed an increase in access to and intensity of VA SUD care associated with increased funding. The VA was able to increase funding for and expand the population to which it offered SUD treatment without diminishing internal access and intensity. Published by Elsevier Inc.

    Full Text Available Substance misuse is frequently encountered in the psychiatric emergency service (PES and may take many forms, ranging from formal DSM-IV diagnoses to less obvious entities such as hazardous consumption. Detecting such patients using traditional screening instruments has proved problematic. We therefore undertook this study to more fully characterize substance misuse in the PES and to determine whether certain variables might help better screen these patients. We used a prospectively acquired database of over 18,000 visits made to four PESs during a 2-year period in the province of Quebec, Canada. One of the variables acquired was a subjective rating by the nursing staff as to whether substance misuse was a contributing factor to the visit (graded as direct, indirect, or not at all. Substance misuse accounted for 21% of all diagnoses and alcohol was the most frequent substance used. Patients were divided into those with primary (PSM, comorbid (CSM or no substance misuse (NSM. Depressive disorders were the most frequent primary diagnoses in CSM, whereas personality and substance misuse disorders were frequent secondary diagnoses in PSM. Although many variables significantly differentiated the three groups, few were sufficiently detailed to be used as potential screening tools. Those situations that did have sufficient details included those with a previous history of substance misuse, substance misuse within 48 hours of the visit, and visits graded by the nursing staff as being directly and/or indirectly related to substance misuse. Variables related to substance misuse itself were the primary predictors of PSM and, less significantly, CSM. The nursing staff rating, although promising, was obtained in less than 30% of all visits, rendering its practical use difficult to assess.

    Little is known about the needs or characteristics of transgender individuals in substance abuse treatment settings. Transgender (n=199) and non-transgender (cisgender, n=13440) individuals were compared on psychosocial factors related to treatment, health risk behaviors, medical and mental health status and utilization, and substance use behaviors within a database that documented individuals entering substance abuse treatment in San Francisco, CA from 2007–2009 using logistic and linear regression analyses (run separately by identified gender). Transgender men (assigned birth sex of female) differed from cisgender men across many psychosocial factors, including having more recent employment, less legal system involvement, greater incidence of living with a substance abuser, and greater family conflict, while transgender women (assigned birth sex of male) were less likely to have minor children than cisgender women. Transgender women reported greater needle use and HIV testing rates were greater among transgender women. Transgender men and women reported higher rates of physical health problems, mental health diagnoses, and psychiatric medications but there were no differences in service utilization. There were no differences in substance use behaviors except that transgender women were more likely to endorse primary methamphetamine use. Transgender individuals evidence unique strengths and challenges that could inform targeted services in substance abuse treatment. PMID:24561017

    Full Text Available Purpose of the article: The aim of the paper is to uncover ways of managing service offering provided by electrical equipment manufactures in the Czech Republic. The segment is extremely important for Czech industry nowadays, especially because of many companies being subcontractors for the car industry and mechanical engineering. The producers of electric equipment comply with the Czech industry classification CZ-NACE 27. Methodology/methods: The questionnaire in the form of the Likert scale was prepared to gather information about customer services. The respondents were usually directors or managers, e.g. employees with high competencies of knowing customer services in this particular market. The total of 22 companies were included in the survey. Research was focused on the following industries classifications belonging to CZ-NACE 27: CZ-NACE 27, CZ-NACE 271 and CZ-NACE 273. According to Czech Statistical Office the total number of companies belonging to these 3 segments is 136. It means 16,2% companies belonging to CZ-NACE 27 participated in our research. Basic statistical methods were used to analyse the complete database. Scientific aim: The paper deals with the problem of service offering provided by today’s manufacturers. Global understanding of services that manufacturers really develop, sell, deliver and manage is still limited. Findings: Managing service offering provided by today‘s manufacturers shows that 1 Manufacturers not offer only tangible products, but also wide range of services and even information and support. 2 New products are not designed only according to company technicians, but also according to their customers. Their products and services are developed, tested and improved according to their needs. 3 Services provide complex customer care from time product selection to its end. Conclusions: Manufacturers of tangible products need to enlarge their product offering to be able to satisfy customers. Therefore

  2. A rationale and model for addressing tobacco dependence in substance abuse treatment

    Full Text Available Abstract Most persons in drug treatment smoke cigarettes. Until drug treatment facilities systematically treat their patients' tobacco use, millions will flow through the drug treatment system, overcome their primary drug of abuse, but die prematurely from tobacco-related illnesses. This paper reviews the literature on the health benefits of quitting smoking for drug treatment patients, whether smoking causes relapse to other drug or alcohol abuse, the treatment of tobacco dependence, and good and bad times for quitting smoking among drug treatment patients. It also presents a conceptual model and recommendations for treating tobacco in substance abuse treatment, and provides references to internet and paper-copy tools and information for treating tobacco dependence. At present, research on tobacco treatment in drug treatment is in its infancy. Although few drug treatment programs currently offer formal services, many more will likely begin to treat nicotine dependence as external forces and patient demand for these services increases. In the absence of clear guidelines and attention to quality of care, drug treatment programs may adopt smoking cessation services based on cost, convenience, or selection criteria other than efficacy. Because research in this field is relatively new, substance abuse treatment professionals should adhere to the standards of care for the general population, but be prepared to update their practices with emerging interventions that have proven to be effective for patients in drug treatment.

    Most Americans pray; many pray about their health. When they are hospitalized, however, do patients want an offer of prayer from a healthcare provider? This project allowed for the measurement of hospitalized patient's responses to massage therapists' offers of a colloquial prayer after a massage. After the intervention, 78 patients completed questionnaires that elicited quantitative data that were analyzed using uni- and bivariate statistical analyses. In this sample, 88% accepted the offer of prayer, 85% found it helpful, and 51% wanted prayer daily. Patients may welcome prayer, as long as the clinician shows "genuine kindness and respect."

  5. Framework of collagen type I - vasoactive vessels structuring invariant geometric attractor in cancer tissues: insight into biological magnetic field.

    Jairo A Díaz

    Full Text Available In a previous research, we have described and documented self-assembly of geometric triangular chiral hexagon crystal-like complex organizations (GTCHC in human pathological tissues. This article documents and gathers insights into the magnetic field in cancer tissues and also how it generates an invariant functional geometric attractor constituted for collider partners in their entangled environment. The need to identify this hierarquic attractor was born out of the concern to understand how the vascular net of these complexes are organized, and to determine if the spiral vascular subpatterns observed adjacent to GTCHC complexes and their assembly are interrelational. The study focuses on cancer tissues and all the macroscopic and microscopic material in which GTCHC complexes are identified, which have been overlooked so far, and are rigorously revised. This revision follows the same parameters that were established in the initial phase of the investigation, but with a new item: the visualization and documentation of external dorsal serous vascular bed areas in spatial correlation with the localization of GTCHC complexes inside the tumors. Following the standard of the electro-optical collision model, we were able to reproduce and replicate collider patterns, that is, pairs of left and right hand spin-spiraled subpatterns, associated with the orientation of the spinning process that can be an expansion or contraction disposition of light particles. Agreement between this model and tumor data is surprisingly close; electromagnetic spiral patterns generated were identical at the spiral vascular arrangement in connection with GTCHC complexes in malignant tumors. These findings suggest that the framework of collagen type 1 - vasoactive vessels that structure geometric attractors in cancer tissues with invariant morphology sets generate collider partners in their magnetic domain with opposite biological behavior. If these principles are incorporated

  7. The offerings from the Hyperboreans.

    The ancient Greeks believed that the fruits of agriculture could be harvested only if one first appeased the spirit of the primitive avatars from which the edible crop had been evolved over the centuries through hybridization and cultivation. On occasion, this appeasement was secured through the sacrifice of a human victim, a person who for various reasons could be considered to represent a similar primitivism. By the classical age, this extreme form of sacrificial appeasement appears to have been reserved for times of unusual crisis, such as pestilence or natural disaster, for at such times, the resurgent forces of primitivism seemed to threaten the entire civilization with regression back to its wilder origins. Other forms of appeasement were ordinarily substituted for the actual offering of a human victim. Amongst these was the enactment of puberty rites, for the natural growth and maturation of an individual could be thought to symbolize this same evolutionary process. Each infant is born as a wild creature who must develop into a socialized adult through the metaphoric death of its former self as it assumes the responsibilities of civilized life in crossing the threshold to sexual maturity. A similar symbolic victim was customarily represented by the offering of first fruits. A portion of the cultivated crop was prematurely cut and consecrated to redeem and release the ripening harvest from the dangerous contamination with the spirits of its pre-agricultural precedents. On the island of Delos, a special version of this consecration was performed. Each year, the various Greek cities would send a sheaf of unripened grain to the sanctuary of the god Apollo and his twin sister Artemis. Amongst these annual offerings, there was one that was supposed to have originated from the Hyperboreans, a mythical people who were thought to live in the original homeland of the two gods. This special Hyperborean offering differed from the others, for it was said to contain a

    A new method of radiolabelling of humic substances (HS) in the aqueous phase has been developed. Radiolabelling with the short-lived positron-emitter 18 F was carried out via diazonium coupling to electron-rich aromatic residues of the humic substances. Labelling yields of up to 75% were obtained after optimization of the synthetic procedure. Introductory experimental steps were performed for testing the labelling stability of the humic substances with ultrafiltration, electrophoretic and chromatographic methods. (orig.)

    The frequency of suicide attempts and clinical characteristics of attempters among poly-substance abusers and alcoholics were examined. A consecutive sample (n = 260) of in- and outpatients from two Norwegian counties were assessed by Composite International Diagnostic Interview (Axis I disorders), Millon's Clinical Multiaxial Inventory (Axis II disorders) and the Norwegian National Client Assessment Form. When analysing the association between suicide attempters and the range of predictor variables, logistic regression analysis was conducted. Almost half (47%) of the sample reported lifetime suicide attempts; significantly more frequently in poly-substance abusers (58%) than alcoholics (38%). A substance use disorder with duration of >or=15 years and an early onset (suicide attempter after controlling for Axis I disorders. In addition, eating disorders, agoraphobia and major depression were strongly and independently associated with being a suicide attempter. Attempts at preventing suicidal behaviour should not ignore the suicide risk among poly-substance abusers. In addition, prevention of suicidal behaviour demands a treatment programme focusing concomitantly on both addictive behaviour and comorbid psychiatric disorders. Copyright 2006 S. Karger AG, Basel.

    The aim of the present study was to study the personality characteristics and criminal behavior in the substance abusers. The role of various sociodemographic variables in substance abusers, which affected their criminal behavior was also studied. Moreover, in the present study, the personality profile of substance users and nonusers was compared using psychoticism, extraversion, and neuroticism (PEN) inventory. A total of 50 consecutive subjects diagnosed as per International Classification of Diseases-10 criteria for substance abuse, fulfilling the inclusive and exclusive criteria were taken. A well-matched control was also assessed to compare the studied subject using a well-designed semi-structured proforma and PEN inventory. Most of the substance abusers were Hindus, married, belonged to 21-30 age group and urban domicile, and were presently unemployed, educated up to middle class, and belonged to lower socioeconomic status. Family history of substance use was significant in the subjects, and the chief substance of use was opioids. Scores for psychoticism and neuroticism, as well as the criminal behavior was significantly higher in studied subjects. Thus, conclusions drawn were that personality characteristics of the substance abusers differed significantly from the control group and second, the number of variables including occupational status, socioeconomic status, family history of substance use, and type of substance of abuse significantly correlated with the criminal behavior in the substance abusers. Identifying these variables can be the first step in the intervention in substance abusers in order to reduce their future criminal behavior.

    2015-01-01

    Full Text Available Context: The abuse of psychoactive substances which is one of the most important global public health problems begins in adolescence. Adolescents usually start by abusing the gateway substances. They suffer social, economic, physical, and legal consequences on account of use of substances, and this is very worrisome because of the increasing prevalence of use. Aims: The aim was to identify the characteristics of adolescents that use gateway substances. This knowledge shall be utilized in preventive programs. Settings and Design: Cross-sectional study with secondary school adolescents as participants. Subjects and Methods: Multistage sampling technique was used to select 492 respondents and the questionnaire consisted of characteristics of the adolescents, their families and schools and the alcohol, tobacco, cannabis, and stimulant use sections of the World Health Organisation questionnaire for student drug use surveys. Statistical Analysis Used: The data were analyzed using the Statistical Package for Social Sciences, and Chi-square statistics was used. Results: Having a friend who uses substance was significantly associated with tobacco, alcohol, cannabis, and caffeine use while being a male, having a family member that uses substance were significantly associated with tobacco, alcohol, and caffeine use. Older age, lack of satisfaction with the relationship with the teacher and polygamous family background were significantly associated with tobacco use. And finally, lack of satisfaction with the relationship with parents/guardians and having parents or guardians who are not religious were significantly associated with alcohol use. Conclusion: A comprehensive approach is needed to prevent the use of substances; this should target individuals, schools, families, and religious institutions.

    PETRORISK is a modeling framework used to evaluate environmental risk of petroleum substances and human exposure through these routes due to emissions under typical use conditions as required by the European regulation for the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH). Petroleum substances are often complex substances comprised of hundreds to thousands of individual hydrocarbons. The physicochemical, fate, and effects properties of the individual constituents within a petroleum substance can vary over several orders of magnitude, complicating risk assessment. PETRORISK combines the risk assessment strategies used on single chemicals with the hydrocarbon block approach to model complex substances. Blocks are usually defined by available analytical characterization data on substances that are expressed in terms of mass fractions for different structural chemical classes that are specified as a function of C number or boiling point range. The physicochemical and degradation properties of the blocks are determined by the properties of representative constituents in that block. Emissions and predicted exposure concentrations (PEC) are then modeled using mass-weighted individual representative constituents. Overall risk for various environmental compartments at the regional and local level is evaluated by comparing the PECs for individual representative constituents to corresponding predicted no-effect concentrations (PNEC) derived using the Target Lipid Model. Risks to human health are evaluated using the overall predicted human dose resulting from multimedia environmental exposure to a substance-specific derived no-effect level (DNEL). A case study is provided to illustrate how this modeling approach has been applied to assess the risks of kerosene manufacture and use as a fuel. © 2014 SETAC.

    Full text: Government of the Republic of Tajikistan has signed Convention "On prohibition of chemical weapon application"and no chemical weapon (CHW) is produced on the territory of republic. However, the potential production of CHW by individual persons or groups can be organized, using available production and obtaining chemical substances from other countries. Chemical substances, which have strong damage effect, easily, can be synthesized in chemical laboratories. These are general toxic substances, as hydrocyanic acid acid, phosgene, mustard gas, lewisite, sarin and others. The similar chemical substances of industrial significance are produced in Tajikistan: ammonia, chlorine, explosives, caustic soda, carbamide, formaldehyde and others. For industrial needs and agriculture from other countries Tajikistan is receiving the following: sodium cyanide and potassium for gold-mining; mineral acids; pesticides and others. Besides, there are different deposits in Tajikistan, reprocessing of which gives an opportunity to obtain different chemical substances. What can be obtained from chemicals produced in Tajikistan? Chlorine - from this reagent the fluoride chlorine, phosgene COCl_2 and many other compounds are easily synthesized, which are CHW components. Obtained cyanic compounds for gold mining can be used as precursor for neuroparalytic action. A big amount of metallic aluminum is produced in the republic. The Al powder for rocket fuel can be obtained from it. Obtained from other countries pesticides are potential components for CHW creation. A strong control and account of pesticides use is necessary. It is extremely important to control materials, equipment and technologies which allow countries and separate groups to create weapons of mass destruction (WMD). The most important factor is goods identification. Firstly - inspection of external view, labeling, packing specifications, license availability and etc. Strong control of checklists is necessary according

    Despite the well-established finding that American Indian adolescents are at a greater risk of illicit substance use and abuse than the general population, few generalist explanations of deviance have been extended to American Indian substance use. Using a popular generalist explanation of deviance, General Strain Theory, we explore the predictive utility of this model with a subsample of American Indian adolescents from waves one and two of the National Longitudinal Study of Adolescent Health (Add-Health). Overall, we find mixed support for the utility of General Strain Theory to account for American Indian adolescent substance use. While exposure to recent life events, a common measure of stress exposure, was found to be a robust indicator of substance use, we found mixed support for the thesis that negative affect plays a key role in mediating the link between strain and substance use. However, we did find evidence that personal and social resources serve to condition the link between stress exposure and substance use, with parental control, self-restraint, religiosity, and exposure to substance using peers each serving to moderate the association between strain and substance use, albeit in more complex ways than expected.

    2012-01-01

    Radioactive substances were discharged over a wide range from the accident of the Fukushima Daiichi Nuclear Station of Tokyo Electric Power Company. As a result, in sewer system, especially in the combined sewer system that jointly collects rainwater and sewage, radioactive substances accumulated on the surface of urban areas were transferred together with rainwater to sewage plants and accumulated there. In the process of further treatment, radioactive substances were transferred to and concentrated in sewage sludge, and a high concentration of radioactive substances were detected in incineration ash. For this reason, some sewage plants still continuously store dewatered sludge, incinerator ash, etc. This paper introduces the current state of waste treatment from the published data from each local government in Tohoku and Kanto districts. As for the sewer, which is essential as a lifeline, the Ministry of Land, Infrastructure, Transport and Tourism, together with the Japan Sewage Works Association, established 'Investigative Commission on Radioactive Substance Countermeasures in Sewerage System.' This group grasped the damage situation due to radioactive substances, and summarized the measures to be taken by sewage managers, such as the storage method for sewage sludge containing radioactive substances as well as the method for the volume reduction of sewage sludge.

    Peterson, David M

    2015-03-01

    Prescription drug abuse and overdose are rapidly growing problems in the United States. The United States federal Disposal of Controlled Substances Rule became effective 9 October 2014, implementing the Secure and Responsible Drug Disposal Act of 2010 (Disposal Act). These regulations target escalating prescription drug misuse by reducing accumulation of unused controlled substances that may be abused, diverted or accidentally ingested. Clinical areas that can now participate in collecting unused controlled substances include retail pharmacies, hospitals or clinics with an onsite pharmacy, and narcotic treatment programs. Collection methods include placing a controlled substance collection receptacle or instituting a mail-back program. Because prompt onsite destruction of collected items is required of mail-back programs, collection receptacles are more likely to be used in clinical areas. Retail pharmacies and hospitals or clinics with an onsite pharmacy may also place and maintain collection receptacles at long-term care facilities. The Act and Rule are intended to increase controlled substance disposal methods and expand local involvement in collection of unused controlled substances. Potential barriers to participating in controlled substance collection include acquisition of suitable collection receptacles and liners, lack of available space meeting the necessary criteria, lack of employee time for verification and inventory requirements, and program costs.

    Since DSM-IV was published in 1994, its approach to substance use disorders has come under scrutiny. Strengths were identified (notably, reliability and validity of dependence), but concerns have also arisen. The DSM-5 Substance-Related Disorders Work Group considered these issues and recommended revisions for DSM-5. General concerns included whether to retain the division into two main disorders (dependence and abuse), whether substance use disorder criteria should be added or removed, and whether an appropriate substance use disorder severity indicator could be identified. Specific issues included possible addition of withdrawal syndromes for several substances, alignment of nicotine criteria with those for other substances, addition of biomarkers, and inclusion of nonsubstance, behavioral addictions. This article presents the major issues and evidence considered by the work group, which included literature reviews and extensive new data analyses. The work group recommendations for DSM-5 revisions included combining abuse and dependence criteria into a single substance use disorder based on consistent findings from over 200,000 study participants, dropping legal problems and adding craving as criteria, adding cannabis and caffeine withdrawal syndromes, aligning tobacco use disorder criteria with other substance use disorders, and moving gambling disorders to the chapter formerly reserved for substance-related disorders. The proposed changes overcome many problems, while further studies will be needed to address issues for which less data were available. PMID:23903334

    Full Text Available David Baron1, Samir AbolMagd2, Salwa Erfan2, Mona El Rakhawy21Temple University School of Medicine, Philadelphia, PA, USA; 2University of Cairo School of Medicine, Cairo, EgyptAbstract: Drug addicts often come from dysfunctional families. The prevailing view in the literature is that mothers of drug-dependent patients can be characterized by strong emotional bonds and overprotection. Studies suggest that maternal rejection could be a major risk factor of developing drug addiction. This work is a continuation of our previous study of childhood parenting experiences of substance-dependent patients. The aims were to compare the personality profile of mothers of substance-dependent patients and that of mothers of matched control subjects; and to examine the relation between the personality of mothers of addicts, and severity of their offspring’s addiction. The study group consisted of 20 mothers of substance-dependent patients and a control group of 35 mothers of non-dependent subjects; mothers of both groups were age matched. Patients were diagnosed according to DSM IV criteria. Personalities of mothers of both groups were assessed using the Minnesota Multiphasic Personality Inventory (MMPI. Substance-dependent patients (sons were administered the Addiction Severity Index (ASI. The mean scores of the MMPI Scales were higher for mothers of dependent patients compared to mothers of non-dependent subjects. Scores on the depression, hysteria and paranoia scales were significantly higher for mothers of patients (P = 0.03, 0.02, and 0.03, respectively. There was a significant positive correlation between scores of hysteria, and psychopathic deviance and the ASI (P = 0.03 and 0.01, respectively. There were significant negative correlations between scores of social introversion and the ASI drug/alcohol use status (P = 0.007, and family history dimensions (P = 0.003. Mothers of substance-dependent patients showed disturbances in aspects of personalities

    Despite efforts to decrease substance use, rates among sexual minority youth (SMY) remain higher than among heterosexuals. Substance use is a leading contributor to morbidity and mortality in adulthood, and SMY's use of substances is related to poorer mental and emotional health. We sought to document the trends in substance use for a large sample of youth over 14 years with special attention to SMY. In addition, we tested whether there were disparities in substance use behaviors between SMY and heterosexual youth. Last, we examined changes in disparities over time in substance use among SMY. We analyzed data from 8 waves of the Massachusetts YRBS (N = 26,002, M age = 16), from 1999 to 2013, to investigate trends and disparities in current tobacco, alcohol, and cannabis use for heterosexual youth and SMY. We used logistic regression interaction models to test whether these disparities have widened or narrowed for SMY, as compared to heterosexuals, over the span of 14 years. In absolute terms, substance use rates decreased for nearly all youth between 1999 and 2013. There were striking disparities in substance use between heterosexual youth and all sexual minority subgroups. These disparities in substance use narrowed among males but remained unchanged or worsened among females. Conclusions/Importance: Trends in substance use are changing over time, but not in the same ways for all sexual minority subgroups. Patterns are worsening for females. These findings suggest that we need to address the needs of LGB populations in novel ways.

    Full Text Available Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3% questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31% questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%, followed by tobacco use (10.9%, and marijuana (7.6%. Of the students surveyed, 145 (79.2% answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3% responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.

    The utilization of administrative data in substance abuse research has become more widespread than ever. This selective review synthesizes recent extant research from 31 articles to consider what has been learned from using administrative data to conduct longitudinal substance abuse research in four overlapping areas: (1) service access and utilization, (2) underrepresented populations, (3) treatment outcomes, and (4) cost analysis. Despite several notable limitations, administrative data contribute valuable information, particularly in the investigation of service system interactions and outcomes among substance abusers as they unfold and influence each other over the long term. This critical assessment of the advantages and disadvantages of using existing administrative data within a longitudinal framework should stimulate innovative thinking regarding future applications of administrative data for longitudinal substance abuse research purposes.

    A new method of radiolabelling of humic substances (HS) in the aqueous phase has been developed. Radiolabelling with the short-lived positron-emitter {sup 18}F was carried out via diazonium coupling to electron-rich aromatic residues of the humic substances. Labelling yields of up to 75% were obtained after optimization of the synthetic procedure. Introductory experimental steps were performed for testing the labelling stability of the humic substances with ultrafiltration, electrophoretic and chromatographic methods. (orig.)

    Full Text Available Abstract Background A large proportion of people attending residential alcohol and other substance abuse treatment have a co-occurring mental illness. Empirical evidence suggests that it is important to treat both the substance abuse problem and co-occurring mental illness concurrently and in an integrated fashion. However, the majority of residential alcohol and other substance abuse services do not address mental illness in a systematic way. It is likely that computer delivered interventions could improve the ability of substance abuse services to address co-occurring mental illness. This protocol describes a study in which we will assess the effectiveness of adding a computer delivered depression and substance abuse intervention for people who are attending residential alcohol and other substance abuse treatment. Methods/Design Participants will be recruited from residential rehabilitation programs operated by the Australian Salvation Army. All participants who satisfy the diagnostic criteria for an alcohol or other substance dependence disorder will be asked to participate in the study. After completion of a baseline assessment, participants will be randomly assigned to either a computer delivered substance abuse and depression intervention (treatment condition or to a computer-delivered typing tutorial (active control condition. All participants will continue to complete The Salvation Army residential program, a predominantly 12-step based treatment facility. Randomisation will be stratified by gender (Male, Female, length of time the participant has been in the program at the commencement of the study (4 weeks or less, 4 weeks or more, and use of anti-depressant medication (currently prescribed medication, not prescribed medication. Participants in both conditions will complete computer sessions twice per week, over a five-week period. Research staff blind to treatment allocation will complete the assessments at baseline, and then 3, 6, 9

    Full Text Available The research aimed to investigate the phenomena of adolescent depressive symptomology, substance abuse and the relationship between the two phenomena in a South African context. The influence of moderator variables was also examined. Another objective was to determine risk factors for the before mentioned. This was done by using a questionnaire with a sample of 1298 conveniently selected adolescents in a South African high school. It was determined that adolescents become progressively unhappier from 13 to 17 years of age. Girls are more depressed than boys. This research also revealed that adolescent depressive symptomology is significantly and positively correlated with earlier age of onset of substance abuse as well as frequency of usage. There appear to be no gender differences in substance abuse but teenagers from different ethnic and language groups differ in their use of substances. Risk factors for depression and substance abuse included a conflict relationship with parents, the experience of major stressful events, dissatisfaction with school grades and friends’ use of substances.

    The etiological factors and interrelations of juvenile delinquents, with psychiatric morbidity and substance abuse have been continuously debated. Cloninger's Tridimensional Theory of Temperament has been reported to predict patterns of substance abuse and comorbidity. In the current study, we aimed to examine the usability of the theory in predicting juvenile delinquency and substance abuse. Sixty consecutive and newly incarcerated male delinquents with history of substance abuse were recruited from a juvenile correctional facility in northwestern Taiwan from January 2002 through December 2003. All subjects were assessed of their temperament, behavioral problems, and psychiatric disorders on an individual base. The juvenile delinquent subjects with childhood history of attention deficit and hyperactivity disorder (ADHD) were significantly younger, consumed less betel nuts, and had more siblings with history of drug abuse. Consistent with the results of Cloninger's studies, novelty seeking positively correlated to the amount of substance abuse, while harm avoidance inversely correlated in juvenile delinquents. Endemic trend of choice of substance abuse needs to be taken into consideration in future research projects.

  15. Problems of substance abuse: exploitation and control.

    The notion of substance abuse is highly problematic. There is considerable disagreement amongst 'experts' as to the relative hazards and addictive properties of both legally and illegally available substances. There are also widely divergent sub-cultural attitudes to the harmfulness or benefit of drug use. One can assume no social consensus as to the nature of the contemporary 'drug problem', nor about the most appropriate means of dealing with it. There is, however, considerable evidence that criminalization of drug use, and harsh penalties against users and suppliers, are ineffective and counter-productive. Other models of control need to be considered, and in particular the merits and de-merits of the medicalization of drug abuse require examination. However, this is only one aspect of the problem. On the other side are the national and international corporations and syndicates, both legitimate and criminal, that earn vast profits from trade in toxic substances. Tobacco is legally available in every country in the world, and the industry is rarely subject to strict control. Thus the issue of substance abuse and control should be seen in a global context, in which account is taken of both legitimate and underworld operations. In attempts to control international trade in toxic substances, the limited success and the problems of already existing legal controls should be acknowledged. Local awareness and regulation of trade in substances is essential, but not sufficient. Amongst other avenues to be explored is the possibility of diverting presently illicitly grown narcotics into indigenous pharmaceutical industries in the Third World. Some problems with this strategy are noted.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Aim: The aim of the present study was to study the personality characteristics and criminal behavior in the substance abusers. The role of various sociodemographic variables in substance abusers, which affected their criminal behavior was also studied. Moreover, in the present study, the personality profile of substance users and nonusers was compared using psychoticism, extraversion, and neuroticism (PEN inventory. Materials and Methods: A total of 50 consecutive subjects diagnosed as per International Classification of Diseases-10 criteria for substance abuse, fulfilling the inclusive and exclusive criteria were taken. A well-matched control was also assessed to compare the studied subject using a well-designed semi-structured proforma and PEN inventory. Results: Most of the substance abusers were Hindus, married, belonged to 21-30 age group and urban domicile, and were presently unemployed, educated up to middle class, and belonged to lower socioeconomic status. Family history of substance use was significant in the subjects, and the chief substance of use was opioids. Scores for psychoticism and neuroticism, as well as the criminal behavior was significantly higher in studied subjects. Conclusion: Thus, conclusions drawn were that personality characteristics of the substance abusers differed significantly from the control group and second, the number of variables including occupational status, socioeconomic status, family history of substance use, and type of substance of abuse significantly correlated with the criminal behavior in the substance abusers. Identifying these variables can be the first step in the intervention in substance abusers in order to reduce their future criminal behavior.

    Full Text Available Abstract Background The rate of women with substance abuse issues is increasing. Women present with a unique constellation of risk factors and presenting needs, which may include specific needs in their role as mothers. Numerous integrated programs (those with substance use treatment and pregnancy, parenting, or child services have been developed to specifically meet the needs of pregnant and parenting women with substance abuse issues. This synthesis and meta-analysis reviews research in this important and growing area of treatment. Methods We searched PsycINFO, MedLine, PubMed, Web of Science, EMBASE, Proquest Dissertations, Sociological Abstracts, and CINAHL and compiled a database of 21 studies (2 randomized trials, 9 quasi-experimental studies, 10 cohort studies of integrated programs published between 1990 and 2007 with outcome data on maternal substance use. Data were summarized and where possible, meta-analyses were performed, using standardized mean differences (d effect size estimates. Results In the two studies comparing integrated programs to no treatment, effect sizes for urine toxicology and percent using substances significantly favored integrated programs and ranged from 0.18 to 1.41. Studies examining changes in maternal substance use from beginning to end of treatment were statistically significant and medium sized. More specifically, in the five studies measuring severity of drug and alcohol use, the average effect sizes were 0.64 and 0.40, respectively. In the four cohort studies of days of use, the average effect size was 0.52. Of studies comparing integrated to non-integrated programs, four studies assessed urine toxicology and two assessed self-reported abstinence. Overall effect sizes for each measure were not statistically significant (d = -0.09 and 0.22, respectively. Conclusions Findings suggest that integrated programs are effective in reducing maternal substance use. However, integrated programs were not

  20. Prosocial coping and substance use during pregnancy.

    In structured interviews of pregnant inner-city residents, 38 substance users reported more current liking of drugs and polysubstance use, disengagement coping, depressive symptoms, negative affect, and antisocial behavior than did 45 nonusers. During videotaped interviews, trained observers coded less warmth and less prosocial information exchange (e.g., self-disclosure, question asking) among users. Factor analysis of measures of coping and its concomitants yielded a three-factor (prosocial, antisocial, asocial) solution, with asocial and antisocial coping predominating among substance users. These results suggest that coping has emotional, social, and cognitive elements. This study is the first to demonstrate an association between a substance-using lifestyle and limited prosocial information exchange.
