    Introduction Neonatal abstinence syndrome (NAS) is withdrawal syndrome in newborns following birth and is primarily caused by maternal drug use during pregnancy. This study examines trends, population correlates, and policy implications of NAS in two Southwest border states. Materials and Methods A cross-sectional analysis of Hospital Inpatient Discharge Data (HIDD) was utilized to examine the incidence of NAS in the Southwest border states of Arizona (AZ) and New Mexico (NM). All inpatient hospital births in AZ and NM from January 1, 2008 through December 31, 2013 with ICD9-CM codes for NAS (779.5), cocaine (760.72), or narcotics (760.75) were extracted. Results During 2008-2013 there were 1472 NAS cases in AZ and 888 in NM. The overall NAS rate during this period was 2.83 per 1000 births (95% CI 2.68-2.97) in AZ and 5.31 (95% CI 4.96-5.66) in NM. NAS rates increased 157% in AZ and 174% in NM. NAS newborns were more likely to have low birth weight, have respiratory distress, more likely to have feeding difficulties, and more likely to be on state Medicaid insurance. AZ border region (border with Mexico) had NAS rates significantly higher than the state rate (4.06 per 1000 births [95% CI 3.68-4.44] vs. 2.83 [95% CI 2.68-2.97], respectively). In NM, the border region rate (2.09 per 1000 births [95% CI 1.48-2.69]) was significantly lower than the state rate (5.31 [95% CI 4.96-5.66]). Conclusions Despite a dramatic increase in the incidence of NAS in the U.S. and, in particular, the Southwest border states of AZ and NM, there is still scant research on the overall incidence of NAS, its assessment in the southwest border, and associated long-term outcomes. The Healthy Border (HB) 2020 binational initiative of the U.S.-Mexico Border Health Commission is an initiative that addresses several public health priorities that not only include chronic and degenerative diseases, infectious diseases, injury prevention, maternal and child health but also mental health and

    Neonatal abstinence syndrome (NAS) occurs in neonates whose mothers have taken addictive drugs or were under substitution therapy during pregnancy. Incidence numbers of NAS are on the rise globally, even in Austria NAS is not rare anymore. The aim of our survey was to reveal the status quo of dealing with NAS in Austria. A questionnaire was sent to 20 neonatology departments all over Austria, items included questions on scoring, therapy, breast-feeding and follow-up procedures. The response rate was 95%, of which 94.7% had written guidelines concerning NAS. The median number of children being treated per year for NAS was 4. Finnegan scoring system is used in 100% of the responding departments. Morphine is being used most often, in opiate abuse (100%) as well as in multiple substance abuse (44.4%). The most frequent forms of morphine preparation are morphine and diluted tincture of opium. Frequency as well as dosage of medication vary broadly. 61.1% of the departments supported breast-feeding, regulations concerned participation in a substitution programme and general contraindications (HIV, HCV, HBV). Our results revealed that there is a big west-east gradient in patients being treated per year. NAS is not a rare entity anymore in Austria (up to 50 cases per year in Vienna). Our survey showed that most neonatology departments in Austria treat their patients following written guidelines. Although all of them base these guidelines on international recommendations there is no national consensus. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Neonatal abstinence syndrome (NAS refers to the constellation of signs and symptoms exhibited by a newborn of drug-abusing mother. NAS is multisystemic disorder, most frequently involving central nervous and gastrointestinal systems with irritability, high-pitched cry, hyperactive reflexes, increased muscle tone, tremors, generalized convulsions, feeding and sleeping disorders, tachycardia, tachypnea, apnea, termolability and sweating, frequent hiccups, yawning and sneezing, vomiting, diarrhea and dehydration.Intrauterine narcotic disposition can give some other adverse effects beside NAS: fetal distress, premature birth, intrauterine growth retardation, microcephaly, increased incidence of congenital anomalies (cardiac and genitourinary anomalies, cleft palate, biliar atresia. Significantly increased risks of sudden infant’s death syndrome (SIDS, abnormalities in neurocognitive and behavioral development and deficiency in motor functions have also been noticed after the long-term surveys of these children.This paper is a case report of a newborn with developed clinical signs of NAS, but it also discusses diagnostics and management of such cases

    Full Text Available Neonatal Abstinence syndrome (NAS is the result of fetal exposure to illicit or prescription drugs (for example opioids, benzodiazepines, and selective serotonin reuptake inhibitors taken by the mother prenatally. NAS is a complex of symptoms, caused by acute withdrawal of the illicit drug(s used by their mothers during pregnancy, seen in neonates hours or days after being born. In the United States of America around 16% of teenagers and 7% of women between the ages of 18 and 25 use illicit drugs during their pregnancies.

    Full Text Available AbstractBreast milk has been reported to ameliorate the severity and outcome of neonatal abstinence syndrome (NAS. The mechanism of this beneficial effect of breast milk on NAS remains unclear, as the negligible amount of methadone transmitted via breast milk is unlikely to have an impact on NAS. The aim of this study was to compare the impact of different feeding modalities on the onset of NAS.A retrospective medical record review was conducted on one hundred and ninety-four methadone maintained mother/infant dyads. Infants were categorized on the first 2 days of life as predominantly breastfed, fed expressed human breast milk or formula fed. The feeding categories were then analyzed using the onset of NAS as the outcome measure. After adjusting for confounders, there was no significant effect of the modality of feeding on the rates of NAS requiring treatment (p=0.11. Breastfeeding significantly delayed the onset of NAS (p=0.04The act of breastfeeding in the first two days of life had no effect on whether an infant required treatment for NAS when compared to those fed EBM or formula. This only suggests that the advantages of breastfeeding on NAS cannot be substantiated in a small cohort and should not discourage breastfeeding.

    Drug overdose and opioid-involved deaths continue to increase across the United States. An end-condition related to opioid abuse is neonatal abstinence syndrome (NAS). The implications for pregnant or post-partum women using an opioid, whether prescribed or illicit, can have significant effects on their infant. First described in the 1970s, NAS is defined as a postnatal drug withdrawal syndrome that primarily occurs in opioid-exposed infants. There are no nationally accepted, evidence-based treatment protocols for these infants. Pediatric dentists should be cognizant of potential dental development issues and developmental delays in children with NAS. Basic behavior guidance techniques, such as tell-show-do, may not be as effective. In addition, adherence to prescription drug monitoring programs can help identify patients who may have received multiple opioids, alerting the provider to possible misuse or abuse. The purpose of this paper was to provide background information on the incidences and potential dental implications for children with neonatal abstinence syndrome.

    Full Text Available Introduction. Neonatal abstinence syndrome (NAS refers to a newborn neurological, gastrointestinal and/or respiratory disorder if a newborn was exposed to psychoactive substances in the intrauterine period. NAS is difficult to diagnose due to unreliability of the data on addictive substances use during pregnancy, limited possibilities of the prenatal exposure diagnosis and postnatal substance detection, which all lead to diagnostic dilemmas. Objective. The aim of this study was to indicate the problems in patients with early NAS diagnosis in the maternity ward and the importance of clinical presentation used as a guide toward the diagnosis. Methods. This retrospective study included five term eutrophic newborns with high Apgar score, good adaptation in the first day and with clinical presentation of NAS during the second day of life. The clinical presentation was dominated by irritability, increased wakefulness, increased muscle tone, shrilly crying, tremors, problems with accepting food, tachypnea, subfebrility and hyperhidrosis. Finnegan scale was introduced in order to diagnose NAS and apply the therapy. Single-medication therapy of phenobarbitone was applied in four cases and a combination of phenobarbitone and morphine in one case. For toxicological analysis newborns’ urine samples were used. Results. Conditions such as perinatal asphyxia, infection, hunger, polycythemia, hypoglycemia or hypocalcemia were excluded. Finnegan score implied that pharmacological treatment had to be administered. The discrepancy between the NAS anamnesis and toxicological analysis existed. Response to the treatment was positive in all cases. Conclusion. NAS is a multisystemic disorder and should be suspected when it is noticed that children exhibit characteristic signs. However, other pathological conditions have to be excluded. Quantification according to the adopted scales for NAS leads toward appropriate treatment and recovery of the newborns.

    An increasing number of infants are diagnosed with neonatal abstinence syndrome (NAS). The study's primary objectives were to describe an academic medical center's level IV neonatal ICU's (NICU's) comprehensive outpatient NAS management effort, measure guideline compliance, and assess its safety. Secondary objectives were to describe the duration and cumulative methadone exposure, and to improve parent and provider knowledge of NAS. The study included 22 infants having a gestational age of 35-41 weeks, diagnosed with NAS, and discharged for outpatient methadone management. Discharges spanned 10 months and included 3 improvement periods. The outpatient program includes comprehensive discharge planning, a focused electronic health record (EHR) template, management guidelines, and parent and provider education. Providers complied with using the outpatient management guideline and EHR template, and assessed weight, NAS symptoms, and methadone dose during appointments. Two infants required NAS-related hospital readmission in the study period. From improvement period 1 to period 3 there was no difference in total outpatient days on methadone (58, 53, 74 days, respectively) or cumulative methadone dose (2.7, 2.6, 3.1mg/kg, respectively). A downward trend pattern in cumulative methadone exposure was noted in improvement period 2. Pre- and postimplementation surveys revealed that after implementation, parents had better understanding of NAS before delivery (71% vs. 100%, p = 0.009), while providers had increased comfort with outpatient management (24% vs. 67%, p management can be safe when a comprehensive management program is implemented and can result in provider compliance with the program.

    AIM: To determine if there is a relationship between maternal methadone dose in pregnancy and the diagnosis or medical treatment of neonatal abstinence syndrome (NAS). METHODS: PubMed, EMBASE, the Cochrane Library and PsychINFO were searched for studies reporting on methadone use in pregnancy and NAS (1966-2009). The relative risk (RR) of NAS was compared for methadone doses above versus below a range of cut-off points. Summary RRs and 95% confidence intervals (CI) were estimated using random effects meta-analysis. Sensitivity analyses explored the impact of limiting meta-analyses to prospective studies or studies using an objective scoring system to diagnose NAS. RESULTS: A total of 67 studies met inclusion criteria for the systematic review; 29 were included in the meta-analysis. Any differences in the incidence of NAS in infants of women on higher compared with lower doses were statistically non-significant in analyses restricted to prospective studies or to those using an objective scoring system to diagnose NAS. CONCLUSIONS: Severity of the neonatal abstinence syndrome does not appear to differ according to whether mothers are on high- or low-dose methadone maintenance therapy.

    Full Text Available Neonatal abstinence syndrome (NAS refers to a constellation of signs that are present in some newborn infants resulting from the abrupt cessation of passive transfer of maternal opioids used during pregnancy. The classic NAS refers to infants born to mothers who used opioids during pregnancy, but the term has broadened to include infants whose mothers have used or abused other psychoactive substances during pregnancy that contribute to the expression of the syndrome. Pregnant women who use opioids do so illicitly, and/or as medically prescribed for pain relief, and/or as medication assisted treatment for opioid dependence. The first case of NAS in infants and the subsequent treatment (or lack thereof was reported in 1875 and was called Congenital Morphinism. By 2012, the incidence of NAS increased to more than 30 per 1,000 hospital live births, along with an increase in the number of infants being treated pharmacologically for NAS, resulting in an increase in the length of stay and healthcare expenses. We present historical references on NAS, the various factors and events that led to its increasing prevalence and today’s current epidemic. We also review the current tools to assess infants with NAS and treatment options in its management.

    Neonatal abstinence syndrome (NAS) is a complicated medical condition with treatment regimens that traditionally have included methadone and other opioids, barbiturates, and benzodiazepines. We describe a case series in which clonidine was used for the prevention and management of patients with NAS. Medical records of infants treated with clonidine for NAS from January 2003 to March 2006 were reviewed for gestational age, birth weight, NAS score, dose of clonidine, duration of treatment, and additional medications required. Fourteen patients were identified. The mean gestational age was 30.1 weeks (range 24.4-40.7 weeks); three patients were full-term. Eleven had been on intravenous fentanyl for sedation; three were born to opioid-dependent mothers. All patients were treated with clonidine, administered in doses of 0.5-1.0 mcg/kg orally every 6 h. No patient received opioids. Mean duration of treatment was 6.8 days (range 4-15). Mean abstinence scores were 6.4 pretreatment (range 0-20) and 1.9 posttreatment (range 0-5). No patients suffered an adverse event (hypotension, bradycardia, excessive sedation, and oxygen desaturation) from clonidine administration, and no seizures were identified. Our data suggest that clonidine may be a reasonable alternative to more traditional agents used to prevent or treat NAS. We agree with the statement of the American Academy of Pediatrics Committee on Drugs that states that larger trials and pharmacologic data are needed before the routine use of clonidine can be recommended.

    This study explored the experiences of NICU nurses in caring for infants with neonatal abstinence syndrome (NAS). A qualitative research approach was used with open-ended questions employing computer-assisted personal interviews. Fourteen NICU nurses employed in a regional hospital provided responses. The nurses reflected a personal struggle between a desire to employ their technical and critical nursing skills and the need to provide expected maternal care to NAS infants. Other themes included frustration and burnout, challenges to values about parenting, and increased awareness of drug use in the community and at home. The results suggest that nurses underrate the skill required to care for infants with NAS. The level of knowledge, patience, and commitment to these newborns should be reframed to increase job satisfaction, and education should be offered to nurses about women struggling with addictions.

    The incidence of opioid abuse and subsequent drug withdrawal is exponentially on the rise in the United States for many populations including newborns who are born to drug-addicted mothers. These newborns often exhibit symptoms of neonatal abstinence syndrome (NAS) within 24 to 72 hours of birth. Treatment of NAS includes monitoring of withdrawal symptoms, managing physiological parameters, and the use of supportive and pharmacologic treatments. Although a few randomized controlled trials exist, studies on supportive intervention are generally limited by small sample sizes, case study reports, expert opinions, and descriptive design. Few studies address the safety of Reiki for newborns at risk for NAS using neonatal parameters. This pilot study addresses feasibility and demonstrates that Reiki is safe when administered to this high-risk population. Considerations for future studies are discussed. PMID:29315084

    Incidence of neonatal abstinence syndrome (NAS) is increasing due to the rise in opioid use. Rural states like Kentucky have been disproportionally impacted by opioid abuse, and this study determines NAS burden nationally and in Kentucky while quantifying differences in access to care between Appalachian and non-Appalachian counties. NAS rates were calculated using National (2013) and Kentucky (2008-2014) National Inpatient Sample discharge data. Births were identified using International Classification of Diseases v9 code 779.5 and live birth codes V30.x-V38.x. Counties were classified as rural, micropolitan, or metropolitan using census data. Proximity analysis was conducted via mapping from ZIP code centroid to nearest opioid treatment facility. Distance to treatment facilities was calculated and then compared using nonparametric testing for counties by rural and Appalachian status. NAS cases tripled from 2008 to 2014 in Kentucky counties, with a 2013 NAS rate more than double the national NAS rate. Rural and Appalachian counties experienced an NAS increase per 1,000 births that was 2-2.5 times higher than urban/non-Appalachian counties, with a greater number of NAS births overall in Appalachian counties. All opioid treatment facility types were further from rural patients than micropolitan/metropolitan patients (P < .001), as well as further for Appalachians versus non-Appalachians (P < .001, all facility types). NAS burden disparately affects rural and Appalachian Kentucky counties, while treatment options are disproportionately further away for these residents. Policy efforts to increase NAS prevention and encourage opioid abuse treatment uptake in pregnant women should address rural and Appalachian disparities. © 2017 National Rural Health Association.

    Current pharmacologic treatment of the neonatal abstinence syndrome with morphine is associated with a lengthy duration of therapy and hospitalization. Buprenorphine may be more effective than morphine for this indication. In this single-site, double-blind, double-dummy clinical trial, we randomly assigned 63 term infants (≥37 weeks of gestation) who had been exposed to opioids in utero and who had signs of the neonatal abstinence syndrome to receive either sublingual buprenorphine or oral morphine. Infants with symptoms that were not controlled with the maximum dose of opioid were treated with adjunctive phenobarbital. The primary end point was the duration of treatment for symptoms of neonatal opioid withdrawal. Secondary clinical end points were the length of hospital stay, the percentage of infants who required supplemental treatment with phenobarbital, and safety. The median duration of treatment was significantly shorter with buprenorphine than with morphine (15 days vs. 28 days), as was the median length of hospital stay (21 days vs. 33 days) (Pbuprenorphine group and in 7 of 30 infants (23%) in the morphine group (P=0.36). Rates of adverse events were similar in the two groups. Among infants with the neonatal abstinence syndrome, treatment with sublingual buprenorphine resulted in a shorter duration of treatment and shorter length of hospital stay than treatment with oral morphine, with similar rates of adverse events.

    To determine whether concurrent in utero exposure to buprenorphine and antidepressants impacts the course of neonatal abstinence syndrome (NAS) in infants. A retrospective cohort study of 148 infants who were exposed to buprenorphine during pregnancy. Univariate and bivariate analyses were used to examine associations between concurrent maternal use of buprenorphine and antidepressants as compared to maternal use of buprenorphine alone. The time to onset of NAS resolution was significantly longer in infants exposed to both buprenorphine and antidepressants during pregnancy when compared to those exposed to buprenorphine alone (129.8 h versus 70.2 h, p = 0.042). Women who are prescribed both antidepressants and buprenorphine during pregnancy should be counseled about the possibility of a prolonged course of neonatal abstinence syndrome.

    The opioid epidemic is a public health threat with consequences affecting newborns. Neonatal Abstinence Syndrome (NAS) is a constellation of withdrawal symptoms resulting primarily from in utero opioid exposure. The purpose of this study was to examine NAS and drug-specific trends in West Virginia (WV), where rurality-related issues are largely present. The 2007-2013 WV Health Care Authority, Uniform Billing Data were analyzed for 119,605 newborn admissions with 1,974 NAS diagnoses. NAS (ICD9-CM 779.5) and exposure diagnostic codes for opioids, hallucinogens, and cocaine were utilized as incidence rate (IR) per 1,000 live births. Between 2007 and 2013, NAS IR significantly increased from 7.74 to 31.56 per 1,000 live births per year (Z: -19.10, P < .0001). During this time period, opioid exposure increased (Z: -9.56, P < .0001), while cocaine exposure decreased (Z: 3.62, P = .0003). In 2013, the southeastern region of the state had the highest NAS IR of 48.76 per 1,000 live births. NAS infants were more likely to experience other clinical conditions, longer hospital stay, and be insured by Medicaid. Statewide NAS IR increased 4-fold over the study period, with rates over 3 times the national annual averages. This alarming trend is deleterious for the health of WV mother-child dyads and it strains the state's health care system. Therefore, WV has a unique need for prenatal public health drug treatment and prevention resources, specifically targeting the southeastern region. Further examination of maternal drug-specific trends and general underutilization of neonatal exposure ICD-9-CM codes is indicated. © 2016 National Rural Health Association.

    Neonatal abstinence syndrome (NAS) from in utero opioid exposure is highly variable with genetic factors appearing to play an important role. Epigenetic changes in cytosine:guanine (CpG) dinucleotide methylation can occur after drug exposure and may help to explain NAS variability. We correlated DNA methylation levels in the mu-opioid receptor (OPRM1) promoter in opioid-exposed infants with NAS outcomes. DNA samples from cord blood or saliva were analyzed for 86 infants who were being treated for NAS according to institutional protocol. Methylation levels at 16 OPRM1 CpG sites were determined and correlated with NAS outcome measures, including need for treatment, treatment with ≥ 2 medications, and length of hospital stay. We adjusted for covariates and multiple genetic testing. Sixty-five percent of infants required treatment for NAS, and 24% required ≥ 2 medications. Hypermethylation of the OPRM1 promoter was measured at the -10 CpG in treated vs nontreated infants (adjusted difference δ = 3.2% [95% CI, 0.3-6.0%], P = .03; nonsignificant after multiple testing correction). There was hypermethylation at the -14 (δ = 4.9% [95% CI, 1.8%-8.1%], P = .003), -10 (δ = 5.0% [95% CI, 2.3-7.7%], P = .0005), and +84 (δ = 3.5% [95% CI, 0.6-6.4], P = .02) CpG sites in infants requiring ≥ 2 medications, which remained significant for -14 and -10 after multiple testing correction. Increased methylation within the OPRM1 promoter is associated with worse NAS outcomes, consistent with gene silencing. Copyright © 2014 Elsevier Inc. All rights reserved.

    Neonatal abstinence syndrome (NAS) is a drug withdrawal syndrome, secondary to in utero chemical exposure and characterised by tremor, irritability and feed intolerance. It often requires prolonged hospital treatment and separation of families. Outpatient therapy may reduce this burden, but current literature is sparse. This review aimed to evaluate the safety and efficacy of our home-based detoxification programme and compare it with standard inpatient care. Infants requiring treatment for NAS between January 2004 and December 2010 were reviewed. Data on demographics, drug exposure, length of stay and type of therapy were compared between infants selected for home-based therapy and those treated conventionally. Of the 118 infants who were admitted for treatment of NAS, 38 (32%) were managed at home. Infants receiving home-based detoxification had shorter hospital stays (mean 19 days vs. 39 days), with no increase in total duration of treatment (mean 36 days vs. 41 days), and were more likely to be breastfeeding on discharge from hospital care (45% vs. 22%). In selected infants, home-based detoxification is associated with reduced hospital stays and increased rates of breastfeeding, without prolonging therapy. Safety of the infants remains paramount, which precludes many from entering such a programme. ©2014 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Opioid exposure during pregnancy is a potential risk factor for the developing central nervous system of the fetus. We studied evoked responses in buprenorphine-exposed newborns who displayed neonatal abstinence syndrome (NAS) to elucidate the possible alterations in functioning of the somatosensory and auditory systems. We compared somatosensory (SEFs) and auditory evoked magnetic fields (AEFs), recorded with magnetoencephalography (MEG), of 11 prenatally buprenorphine-exposed newborns with those of 12 healthy newborns. Peak latencies, source strength and location of SEFs or AEFs were recorded. AEFs were present in all buprenorphine-exposed newborns without significant differences from those of healthy newborns. In contrast, though no group level differences in SEFs existed, at individual level the response deviated from the typical neonatal morphology in four buprenorphine-exposed newborns. Although buprenorphine exposure during pregnancy does not seem to cause constant deficiencies in somatosensory or auditory processing, in some newborns the typical development of somatosensory networks may be - at least transiently - disrupted.

    The prevalence of neonatal abstinence syndrome (NAS) is increasing globally resulting in an increased incidence of adverse neonatal outcomes and health system costs. Evidence regarding the effectiveness of NAS prevention and management strategies is very weak and further research initiatives are critically needed to support meta-analysis and clinical practice guidelines. In NAS research, the choice of outcomes and the use of valid, responsive and feasible measurement instruments are crucial. There is currently no consensus and evidence-based core outcome set (COS) for NAS. The development of the NAS-COS will include five stages led by an international Multidisciplinary Steering Committee: (1) qualitative interviews with parents/families and a systematic review (SR) to identify items for inclusion in a COS. The SR will also identify participants for the Delphi survey, (2) a three-round Delphi survey to gain expert opinion on the importance of health outcomes influencing NAS management decisions, (3), a consensus meeting to finalize the items and definitions with experts and COS users, (4) feasibility and pilot testing, development of the COS and explanatory document and (5) implementation planning. Since standardized outcome measurement and reporting will improve NAS clinical research consistency, efficacy and impact, this COS will reflect the minimum set of health outcomes which should be measured in trials evaluating interventions for preventing or treating NAS.

The clinical presentation consists of neurological respiratory, gastrointestinal, and vasomotor disturbances. All infants require observation and supportive care to ensure appropriate adaptation and growth in the newborn period. A smaller percentage may also require additional pharmacotherapy, depending on the specific gestational substance exposure. Women should be counseled antenatally about the possible neonatal effects, and mother–baby dyad care should be implemented for this particular patient population.Keywords: neonatal withdrawal, opioids, marijuana, cocaine, benzodiazepines, selective serotonin reuptake inhibitors

    To compare the duration of opioid treatment and length of stay among infants treated for neonatal abstinence syndrome (NAS) by using a pilot buprenorphine vs conventional methadone treatment protocol. This retrospective cohort analysis evaluated infants who received pharmacotherapy for NAS at 6 hospitals in Southwest Ohio from January 2012 through August 2014. A single neonatology provider group used a standardized methadone protocol across all 6 hospitals. However, at one of the sites, infants were managed with a buprenorphine protocol unless they had experienced chronic in utero exposure to methadone. Linear mixed models were used to calculate adjusted mean duration of opioid treatment and length of inpatient hospitalization with 95% CIs in infants treated with oral methadone compared with sublingual buprenorphine. The use of adjunct therapy was examined as a secondary outcome. A total of 201 infants with NAS were treated with either buprenorphine (n = 38) or methadone (n = 163) after intrauterine exposure to short-acting opioids or buprenorphine. Buprenorphine therapy was associated with a shorter course of opioid treatment of 9.4 (CI 7.1-11.7) vs 14.0 (12.6-15.4) days (P methadone therapy. No difference was detected in the use of adjunct therapy (23.7% vs 25.8%, P = .79) between treatment groups. The choice of pharmacotherapeutic agent is an important determinant of hospital outcomes in infants with NAS. Sublingual buprenorphine may be superior to methadone for management of NAS in infants with select intrauterine opioid exposures. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available BackgroundThe development of suck–swallow–breath rhythms during non-nutritive suck (NNS may be an indicator of neurologic integrity. We have described swallow–breath (SwBr interaction and phase of respiration (POR with swallow during NNS in low-risk preterm (LRP infants. NNS in infants with neonatal abstinence syndrome (NAS has not been described with our method.MethodSuckle, swallow, thoracic motion, and nasal airflow were measured during NNS in 10 infants with NAS and 12 unaffected infants (control. Logistic regression models were fit to describe the three types of SwBr and five types of POR in terms of the independent variables (gender, gestational age, birth weight, postmenstrual age, weeks postfirst nipple feed and swallows per study. We also compared the NAS group to 16 LRP infants.ResultsIn the NAS group, there were 94 swallows in 18 studies. In the control group, there were 94 swallows in 12 studies. There were statistical differences between groups for all three types of SwBr. The distribution of SwBr in NAS was similar to LRP infants with NAS having fewer swallows with attenuated respiration and more with central apnea. For POR, there were few differences. Over time, the distribution of SwBr in NAS infants approaches that of control infants.DiscussionVariability in SwBr and POR during NNS may represent neurologic dysfunction in infants with NAS. Specifically, term infants with NAS display an immature pattern of SwBr making them more similar to preterm infants, rather than a unique pathology. The distribution of SwBr and POR in NAS infants becomes more like term infants, possibly representing catch-up development as the NAS symptoms resolve.ConclusionSwBr in babies with NAS is different from that of unaffected term infants, actually being similar to preterm infants. Infants with NAS exhibit a dysmature pattern of NNS development which resolves over time.

    Conducting and analyzing clinical trials in vulnerable neonates are extremely challenging. The aim of this analysis is to develop a morphine population pharmacokinetics (PK) model using data collected during a randomized control trial in neonates with abstinence syndrome (NAS). A 3-compartment morphine structural PK model after intravenous (IV) administration from previously published work was utilized as prior, whereas an allometric scaling method with physiological consideration was used to extrapolate a PK profile from adults to pediatrics. The absorption rate constant and bioavailability were estimated in NAS after oral administration of diluted tincture of opium (DTO). Goodness-of-fit plots along with normalized prediction distribution error and bootstrap method were performed for model evaluation. We successfully extrapolated the PK profile from adults to pediatrics after IV administration. The estimated first-order absorption rate constant and bioavailability were 0.751 hour(-1) and 48.5%, respectively. Model evaluations showed that the model can accurately and precisely describe the observed data. The population pharmacokinetic model we derived for morphine after oral administration of DTO is reasonable and acceptable; therefore, it can be used to describe the PK and guide future studies. The integration of the previous population PK knowledge as prior information successfully overcomes the logistic and practical issue in vulnerable neonate population. © 2016, The American College of Clinical Pharmacology.

    There is little empirical evidence that guides management of infants with neonatal abstinence syndrome. The standard of care first described in the 1970s is still prevalent today, although it has never been tested in this population. Standard of care interventions include decreasing external stimulation, holding, nonnutritive sucking, swaddling, pressure/rubbing, and rocking. These interventions meet the goals of nonpharmacologic interventions, which are to facilitate parental attachment and decrease external stimuli. Many nursing interventions used in infants with neonatal abstinence syndrome have been tested in low-birth-weight infants, whose treatment often includes the same goals. Those interventions include music therapy, kangaroo care, massage, and use of nonoscillating water beds. Nursing attitude has also been shown to be impactful on parental attachment. The American Academy of Pediatrics recommends breast-feeding in infants whose mothers are on methadone who do not have any other contraindication. It also provides guidelines for pharmacologic management but cannot provide specific recommendations about a standard first dose, escalation, or weaning schedule. Buprenorphine has some evidence about its safety in newborns with neonatal abstinence syndrome, but high-powered studies on its efficacy are currently lacking. There are many opportunities for both evidence-based projects and nursing research projects in this population.

    To provide absolute and relative risk estimates of neonatal abstinence syndrome (NAS) based on duration and timing of prescription opioid use during pregnancy in the presence or absence of additional NAS risk factors of history of opioid misuse or dependence, misuse of other substances, non-opioid psychotropic drug use, and smoking. Observational cohort study. Medicaid data from 46 US states. Pregnant women filling at least one prescription for an opioid analgesic at any time during pregnancy for whom opioid exposure characteristics including duration of therapy: short term (opioid prescriptions, corresponding to an absolute risk of 5.9 per 1000 deliveries (95% confidence interval 5.6 to 6.2). Long term opioid use during pregnancy resulted in higher absolute risk of NAS per 1000 deliveries in the presence of additional risk factors of known opioid misuse (220.2 (200.8 to 241.0)), alcohol or other drug misuse (30.8 (26.1 to 36.0)), exposure to other psychotropic medications (13.1 (10.6 to 16.1)), and smoking (6.6 (4.3 to 9.6)) than in the absence of any of these risk factors (4.2 (3.3 to 5.4)). The corresponding risk estimates for short term use were 192.0 (175.8 to 209.3), 7.0 (6.0 to 8.2), 2.0 (1.5 to 2.6), 1.5 (1.0 to 2.0), and 0.7 (0.6 to 0.8) per 1000 deliveries, respectively. In propensity score matched analyses, long term prescription opioid use compared with short term use and late use compared with early use in pregnancy demonstrated greater risk of NAS (risk ratios 2.05 (95% confidence interval 1.81 to 2.33) and 1.24 (1.12 to 1.38), respectively). Use of prescription opioids during pregnancy is associated with a low absolute risk of NAS in the absence of additional risk factors. Long term use compared with short term use and late use compared with early use of prescription opioids are associated with increased NAS risk independent of additional risk factors. © Desai et al 2015.

    Compare duration of treatment of neonatal abstinence syndrome between methadone and morphine. A prospective, double-masked, randomized trial at a single site. Randomization of methadone or morphine was stratified for maternal treatment with methadone or buprenorphine. Inclusion criteria were (i) maternal treatment with prescribed methadone or buprenorphine, (ii) withdrawal treatment criteria, (iii) adjusted gestational age ⩾35(0/7) weeks and (iv) medically stable. Primary outcome was length of opioid treatment. From January 2011 through October 2012, 78 infants were eligible for the study: 41 methadone-exposed and 37 buprenorphine-exposed. Consent was obtained from 31 mothers, 13/41 (32%) methadone-treated and 18/37 (49%) buprenorphine-treated. Length of opioid treatment was significantly shorter for methadone than morphine treatment, median 14 versus 21 days (P=0.008). Methadone had a shorter length of neonatal withdrawal treatment compared with morphine. Owing to the smaller sample size and single site, a larger randomized study is needed.

    This review focuses on the neurobiological processes involved in achieving successful abstinence from drugs of abuse. While there is clinical and public health value in knowing if the deficits associated with drug use correct with abstinence, studying the neurobiology that underlies successful abstinence can also illuminate the processes that enable drug-dependent individuals to successfully quit. Here, we review studies on human addicts that assess the neurobiological changes that arise with abstinence and the neurobiological predictors of successfully avoiding relapse. The literature, while modest in size, suggests that abstinence is associated with improvement in prefrontal structure and function, which may underscore the importance of prefrontally-mediated cognitive control processes in avoiding relapse. Given the implication that the prefrontal cortex may be an important target for therapeutic interventions, we also review evidence indicating the efficacy of cognitive control training for abstinence.

    In April 2016, the Eunice Kennedy Shriver National Institute of Child Health and Human Development invited experts to a workshop to address numerous knowledge gaps and to review the evidence for the screening and management of opioid use in pregnancy and neonatal abstinence syndrome. The rising prevalence of opioid use in pregnancy has led to a concomitant dramatic fivefold increase in neonatal abstinence syndrome over the past decade. Experts from diverse disciplines addressed research gaps in the following areas: 1) optimal screening for opioid use in pregnancy; 2) complications of pregnancy associated with opioid use; 3) appropriate treatments for pregnant women with opioid use disorders; 4) the best approaches for detecting, treating, and managing newborns with neonatal abstinence syndrome; and 5) the long-term effects of prenatal opioid exposure on children. Workshop participants identified key scientific opportunities to advance the understanding of opioid use disorders in pregnancy and to improve outcomes for affected women, their children, and their families. This article provides a summary of the workshop presentations and discussions.

    To study the incidence and patient characteristics of Neonatal Abstinence Syndrome (NAS) in infants who were born to opioid addicted mothers and required NICU admission over the three year period. From 2009 to 2011, data of infants admitted in WVUH NICU with history of maternal drug exposure were extracted and reviewed. Infants born to mothers treated with buprenorphine (BPN) and those with methadone (MTD) were compared. Incidence of drug exposure infants significantly increased in 2011. BPN exposure infants increased substantially while the number of MTD exposure infants did not significantly change. Eighty-one percent of those MTD exposure infants required drug treatment for NAS compared to 26% of BPN exposure infants. Significant increase in opioid exposure infants with NAS was observed in our unit in 2011. Although, the incidence of BPN exposure with NAS increased significantly, only 25% of them required drug treatment.

    2013-10-01

    The senior patient and/or the geriatrician are confronted with a confusing literature describing how patients interested in combating metabolic syndrome, diabesity (diabetes plus obesity) or simple obesity might best proceed. The present paper gives a brief outline of the basic disease processes that underlie metabolic pro-inflammation, including how one might go about devising the most potent and practical detoxification from such metabolic compromise. The role that dietary restriction plays in pro-inflammatory detoxification (detox), including how a modified fast (selective food abstinence) is incorporated into this process, is developed. The unique aspects of geriatric bariatric medicine are elucidated, including the concepts of sarcopenia and the obesity paradox. Important caveats involving the senior seeking weight loss are offered. By the end of the paper, the reader will have a greater appreciation for the challenges and opportunities that lie ahead for geriatric patients who wish to overcome food addiction and reverse pro-inflammatory states of ill-heath. This includes the toxic metabolic processes that create obesity complicated by type 2 diabetes mellitus (T2DM) which collectively we call diabesity. In that regard, diabesity is often the central pathology that leads to the evolution of the metabolic syndrome. The paper also affords the reader a solid review of the neurometabolic processes that effectuate anorexigenic versus orexigenic inputs to obesity that drive food addiction. We argue that these processes lead to either weight gain or weight loss by a tripartite system involving metabolic, addictive and relational levels of organismal functioning. Recalibrating the way we negotiate these three levels of daily functioning often determines success or failure in terms of overcoming metabolic syndrome and food addiction.

  4. Abstinence and neutrality: development and diverse views.

    1994-08-01

    Usually, Freud adopted a technical device for personal or practical reasons and only later formulated its theoretical basis. His conception of abstinence initially seemed designed to curb his own troublesome erotic countertransference. These speculations, while having no bearing on the clinical value of abstinence and related neutrality, do emphasise the necessity to assess their utility objectively, on the basis of clinical data. Diverse views of abstinence and neutrality persist in part because early inconsistencies in Freud's conceptions remain unresolved, and in part because these views are derived from the analyst's personality and character, are not based upon clinical data, but are buttressed by iteration. An approach to empirical assessment is suggested using multiple analyst-observers: (1) to develop reliable criteria for four analyst behaviours: abstinence, neutrality, gratification and suggestion; and (2) to evaluate enhancement or impairment of analytic work. Utilisation of this approach in the supervision of candidates would enhance analytic pedagogy and to some degree facilitate a research orientation in candidates.

    Although withdrawal symptoms are commonly reported by persons seeking treatment for marijuana dependence, the validity and clinical significance of a marijuana withdrawal syndrome has not been established. This controlled outpatient study examined the reliability and specificity of the abstinence effects that occur when daily marijuana users abruptly stop smoking marijuana. Twelve daily marijuana smokers were assessed on 16 consecutive days during which they smoked marijuana as usual (days 1-5), abstained from smoking marijuana (days 6-8), returned to smoking marijuana (days 9-13), and again abstained from smoking marijuana (days 14-16). An overall measure of withdrawal discomfort increased significantly during the abstinence phases and returned to baseline when marijuana smoking resumed. Craving for marijuana, decreased appetite, sleep difficulty, and weight loss reliably changed across the smoking and abstinence phases. Aggression, anger, irritability, restlessness, and strange dreams increased significantly during one abstinence phase, but not the other. Collateral observers confirmed participant reports of these symptoms. This study validated several specific effects of marijuana abstinence in heavy marijuana users, and showed they were reliable and clinically significant. These withdrawal effects appear similar in type and magnitude to those observed in studies of nicotine withdrawal.

São também descritos alguns estudos relevantes que demonstram o envolvimento de outros mecanismos de ação do álcool no sistema nervoso central, como o envolvimento de opióides, entre outras substâncias. O artigo reafirma a importância, para clínicos e pesquisadores, de um sempre maior entendimento do mecanismo de ação central do álcool, pois dele depende a busca por novas opções farmacológicas, tanto para a redução dos danos provocados pelo seu uso crônico, como para o tratamento da síndrome de abstinência a esta substância.The objective of this paper is to review and describe the main neuropharmacological changes caused by the chronic use of alcohol and those observed during its withdrawal period. The results show international data referring to the involvement of monoamine systems, neurotransmitters and calcium channels in both neuroadaptation and tolerance to alcohol effects and withdrawal. Relevant studies showing the participation of other systems in those mechanisms, as opioids and other substances, are also shown. The article reinforces the importance, for both physicians and researchers, of an always growing understanding of alcohol central mechanisms of action. This understanding is necessary to new pharmacological options to alcohol harm reduction as well as to alcohol withdrawal treatment.

    Full Text Available PURPOSE: To investigate the impact of alcohol intoxication and withdrawal on the course of social phobia and panic disorder. METHOD: A group of 41 alcoholic inpatients undergoing detoxification therapy were interviewed using the SCID-I (DSM-IV and questions to detect fluctuations in the course of social phobia and panic disorder as a function of the different phases in alcohol dependence (intoxication, withdrawal, and lucid interval. RESULTS: Only 1 (2.4% patient presented panic disorder throughout life, and 9 (21.9% had panic attacks during alcohol intoxication or during the withdrawal syndrome. Sixteen (39% alcoholic patients showed social phobia with onset prior to drug use. However, drinking eventually became unable to alleviate social phobia symptoms or worsened such symptoms in 31.2% of social-phobic patients. While patients with social phobia reported a significant improvement in psychiatric symptoms during alcohol intoxication, patients experiencing panic attacks worsened significantly during intoxication. In the withdrawal phase, patients with social phobia tended to have more and more intense phobic symptoms. CONCLUSION: Our findings indicate that the impact of alcohol intoxication is different for social phobia as compared to panic disorder, at first decreasing the social-phobic symptoms but later aggravating them. In panic disorder, the impact of intoxication by alcohol is more harmful, at least in the short term.OBJETIVO: Estudar o impacto das fases de intoxicação e de abstinência do uso de álcool sobre o curso da fobia social e do transtorno de pânico.

    Richman, Barbara T.

    A proposed reorganization at the National Academy of Sciences (NAS) would fold the Commission on Natural Resources into the Assembly of Mathematical and Physical Sciences (AMPS) to form what would be called the Commission on Mathematics, Physical Sciences, and Resources. Spurred by NAS President Frank Press, past president of AGU, the merger is part of a reorganization that aims to clarify the division of labor within the National Research Council (NRC). The NAS council approved the general structure of the reorganization; the National Academy of Engineering's council was scheduled to review the matter at its March 12 meeting. Administrative details of the restructuring will not be finalized until the April 3 meeting of the NRC governing board.

    The relationship between subjective social status (SSS), a person's perception of his/her relative position in the social hierarchy, and the ability to achieve long-term smoking abstinence during a specific quit attempt is unknown. The purpose of this study was to examine the relationship between SSS and long-term smoking abstinence among 421 racially/ethnically diverse smokers undergoing a specific quit attempt, as well as the interactive effects of race/ethnicity and sex. The main effects and moderated relationships of SSS on biochemically-confirmed, continuous smoking abstinence through 26 weeks post-quit were examined using continuation ratio logit models adjusted for sociodemographics and smoking characteristics. Even after adjusting for the influence of socioeconomic status and other covariates, smokers endorsing lower SSS were significantly less likely to maintain long-term smoking abstinence during a specific quit attempt than those with higher SSS (OR = 1.14, 95% CI: 1.00 - 1.28; p = 0.044). The statistical significance of this relationship, however, did not vary by race/ethnicity or sex. SSS independently predicts long-term smoking abstinence during a specific quit attempt. SSS may be a useful screener to identify smokers at elevated risk of relapse who may require additional attention to facilitate long-term abstinence. More research is needed to understand the mechanisms underlying the relationship between SSS and long-term smoking abstinence in order to appropriately tailor treatment to facilitate abstinence among lower SSS smokers.

    Social media has been established to bear signals relating to health and well-being states. In this paper, we investigate the potential of social media in characterizing and understanding abstinence from tobacco or alcohol use. While the link between behavior and addiction has been explored in psychology literature, the lack of longitudinal self-reported data on long-term abstinence has challenged addiction research. We leverage the activity spanning almost eight years on two prominent communities on Reddit: StopSmoking and StopDrinking. We use the self-reported "badge" information of nearly a thousand users as gold standard information on their abstinence status to characterize long-term abstinence. We build supervised learning based statistical models that use the linguistic features of the content shared by the users as well as the network structure of their social interactions. Our findings indicate that long-term abstinence from smoking or drinking (~one year) can be distinguished from short-term abstinence (~40 days) with 85% accuracy. We further show that language and interaction on social media offer powerful cues towards characterizing these addiction-related health outcomes. We discuss the implications of our findings in social media and health research, and in the role of social media as a platform for positive behavior change and therapy.

    Cannabis causes lower mortality and morbidity than alcohol and tobacco so it is clinically important if quitting cannabis is associated with substitution with these substances. This study tests if cannabis is substituted with alcohol and/or tobacco during cannabis abstinence, and factors predicting such substitution. A secondary analysis of a prospective community based study quantified cannabis, alcohol and tobacco use with Timeline Follow-back during a two-week voluntary cannabis abstinence and at one-month follow-up in non-treatment seeking cannabis users (n=45). Cannabis use was verified by urine THC-COOH levels. Alcohol use increased by 8 standard units (SU; d=0.48)/week and cigarette use by 14 cigarettes/week (d=0.29) during cannabis abstinence. Those using less of each substance at baseline had greater increases during cannabis abstinence (alcohol Pcannabis use. Increased cigarette use was predicted by cannabis withdrawal related sleep difficulty (insomnia) (P=0.05), restlessness (P=0.03) and physical symptoms (P=0.02). Neither alcohol nor cigarette use increased significantly in those (13.3%, n=6) who remained abstinent from cannabis through to follow-up. Abstaining from cannabis was associated with increases in alcohol and tobacco use that decreased with resumption of cannabis use; however there were no increases in individuals who remained abstinent from cannabis at one-month follow-up. Tobacco use did not increase in those experiencing milder cannabis withdrawal symptoms. Research on substitution in treatment seekers during outpatient cannabis abstinence is needed.

  5. Sex differences in time perception during smoking abstinence.

    Nicotine withdrawal leads to impulsive decision-making, which reflects a preference for smaller, immediate rewards and often prompts a relapse to smoking. The mechanism by which nicotine withdrawal leads to impulsive decision-making is not well known. An essential dimension of decision-making is time perception. Impulsive decisions reflect intolerance of temporal delays and the perception that time is passing more slowly. Sex may be an important factor in impulsive decision-making and time perception, but no studies have investigated whether sex moderates the effects of nicotine withdrawal on impulsive decision-making and time perception. Thirty-three (12 female) adult smokers completed 2 laboratory sessions: following 24-hr abstinence and once smoking-as-usual (order counterbalanced, abstinence biochemically verified). Participants completed 2 time perception tasks, a decision-making task, and self-report measures of craving, withdrawal, and mood. During time reproduction, males overestimated time during abstinence compared to smoking, whereas there was no session effect for females. On the time discrimination task, smokers were less accurate during abstinence, and this effect tended to be stronger among females. In general, males had higher discounting rates compared with females, but there was no effect of abstinence. The current data suggest that the effect of abstinence on time perception may be stronger in males and that males generally exhibit steeper delay discounting rates. Time perception may be an important mechanism in smoking abstinence. Our future work will investigate the role of time perception in smoking relapse and whether this is moderated by sex. © The Author 2015.

    We examined the use of employment-based abstinence reinforcement in out-of-treatment injection drug users, in this secondary analysis of a previously reported trial. Participants (N = 33) could work in the therapeutic workplace, a model employment-based program for drug addiction, for 30 weeks and could earn approximately $10 per hr. During a 4-week induction, participants only had to work to earn pay. After induction, access to the workplace was contingent on enrollment in methadone treatment. After participants met the methadone contingency for 3 weeks, they had to provide opiate-negative urine samples to maintain maximum pay. After participants met those contingencies for 3 weeks, they had to provide opiate- and cocaine-negative urine samples to maintain maximum pay. The percentage of drug-negative urine samples remained stable until the abstinence reinforcement contingency for each drug was applied. The percentage of opiate- and cocaine-negative urine samples increased abruptly and significantly after the opiate- and cocaine-abstinence contingencies, respectively, were applied. These results demonstrate that the sequential administration of employment-based abstinence reinforcement can increase opiate and cocaine abstinence among out-of-treatment injection drug users. © Society for the Experimental Analysis of Behavior.

    Tolerance and dependence induced by chronic delta-9-tetrahydrocannabinol (THC) administration were investigated in mice. The effects on body weight, analgesia and hypothermia were measured during 6 days of treatment (10 or 20 mg kg(-1) THC twice daily). A rapid tolerance to the acute effects was observed from the second THC administration. The selective CB-1 receptor antagonist SR 141716A (10 mg kg(-1)) was administered at the end of the treatment, and somatic and vegetative manifestations of abstinence were evaluated. SR 141716A administration precipitated several somatic signs that included wet dog shakes, frontpaw tremor, ataxia, hunched posture, tremor, ptosis, piloerection, decreased locomotor activity and mastication, which can be interpreted as being part of a withdrawal syndrome. Brains were removed immediately after the behavioural measures and assayed for adenylyl cyclase activity. An increase in basal, forskolin and calcium/calmodulin stimulated adenylyl cyclase activities was specifically observed in the cerebellum of these mice. The motivational effects of THC administration and withdrawal were evaluated by using the place conditioning paradigm. No conditioned change in preference to withdrawal associated environment was observed. In contrast, a conditioned place aversion was produced by the repeated pairing of THC (20 mg kg(-1)), without observing place preference at any of the doses used. This study constitutes a clear behavioural and biochemical model of physical THC withdrawal with no motivational aversive consequences. This model permits an easy quantification of THC abstinence in mice and can be useful for the elucidation of the molecular mechanisms involved in cannabinoid dependence.

  12. Gratitude, abstinence, and alcohol use disorders: Report of a preliminary finding.

    Krentzman, Amy R

    2017-07-01

    Gratitude is a central component of addiction recovery for many, yet it has received scant attention in addiction research. In a sample of 67 individuals entering abstinence-based alcohol-use-disorder treatment, this study employed gratitude and abstinence variables from sequential assessments (baseline, 6months, 12months) to model theorized causal relationships: gratitude would increase pre-post treatment and gratitude after treatment would predict greater percent days abstinent 6months later. Neither hypothesis was supported. This unexpected result led to the theory that gratitude for sobriety was the construct of interest; therefore, the association between gratitude and future abstinence would be positive among those already abstinent. Thus, post-treatment abstinence was tested as a moderator of the effect of gratitude on future abstinence: this effect was statistically significant. For those who were abstinent after treatment, the relationship between gratitude and future abstinence was positive; for those drinking most frequently after treatment, the relationship between gratitude and future abstinence was negative. In this preliminary study, dispositional tendency to affirm that there is much to be thankful for appeared to perpetuate the status quo-frequent drinkers with high gratitude were drinking frequently 6months later; abstinent individuals with high gratitude were abstinent 6months later. Gratitude exercises might be contraindicated for clients who are drinking frequently and have abstinence as their treatment goal. Copyright © 2017 Elsevier Inc. All rights reserved.

    Preliminary evidence, within both adults and adolescents, suggests that the intensity with which cigarettes are smoked (i.e., smoking topography) is predictive of success during a cessation attempt. These reports have also shown topography to be superior compared to other variables, such as cigarettes per day, in the prediction of abstinence. The possibility that gender may influence this predictive relationship has not been evaluated but may be clinically useful in tailoring gender-specific interventions. Within the context of a clinical trial for smoking cessation among women, adult daily smokers completed a laboratory session that included a 1-hour ad libitum smoking period in which measures of topography were collected (N=135). Participants were then randomized to active medication (nicotine patch vs. varenicline) and abstinence was monitored for 4weeks. Among all smoking topography measures and all abstinence outcomes, a moderate association was found between longer puff duration and greater puff volume and continued smoking during the active 4-week treatment phase, but only within the nicotine patch group. Based on the weak topography-abstinence relationship among female smokers found in the current study, future studies should focus on explicit gender comparisons to examine if these associations are specific to or more robust in male smokers. © 2013 Elsevier Ltd.

    2018-03-01

    In this study, we sought to discover if housing in an enriched environment (EE) is an efficacious intervention for encouraging abstinence from cocaine seeking in an animal "conflict" model of abstinence. Sixteen Long-Evans rats were trained in 3-h daily sessions to self-administer a cocaine solution (1 mg/kg/infusion) until each demonstrated a stable pattern of drug-seeking. Afterward, half were placed in EE cages equipped with toys, obstacles, and a running wheel, while the other half were given clean, standard laboratory housing. All rats then completed daily 30-min sessions during which the 2/3 of flooring closest to the self-administration levers was electrified, causing discomfort should they approach the levers; current strength (mA) was increased after every day of drug seeking until the rat ceased activity on the active lever for 3 consecutive sessions (abstinence). Rats housed in EE abstained after fewer days and at lower current strengths than rats in standard housing. These results support the idea that EE administered after the development of a cocaine-taking habit may be an effective strategy to facilitate abstinence. Copyright © 2018 Elsevier Inc.

    High-magnitude and long-duration abstinence reinforcement can promote drug abstinence but can be difficult to finance. Employment may be a vehicle for arranging high-magnitude and long-duration abstinence reinforcement. This study determined if employment-based abstinence reinforcement could increase cocaine abstinence in adults who inject drugs and use cocaine during methadone treatment. Participants could work 4 hr every weekday in a workplace where they could earn about $10.00 per hour in vouchers; they were required to provide routine urine samples. Participants who attended the workplace and provided cocaine-positive urine samples during the initial 4 weeks were invited to work 26 weeks and were randomly assigned to an abstinence-and-work (n = 28) or work-only (n = 28) group. Abstinence-and-work participants had to provide urine samples showing cocaine abstinence to work and maintain maximum pay. Work-only participants could work independent of their urinalysis results. Abstinence-and-work participants provided more (p = .004; OR = 5.80, 95% CI = 2.03-16.56) cocaine-negative urine samples (29%) than did work-only participants (10%). Employment-based abstinence reinforcement can increase cocaine abstinence.

O objetivo deste relato é mostrar um caso de paciente jovem admitido na UTI que desenvolveu síndrome de abstinência alcoólica e tolerância às drogas sedativas, solucionadas somente após o uso de clonidina. RELATO DO CASO: Paciente do sexo masculino, 18 anos, dependente de álcool, tabaco, cocaína e maconha, vítima de acidente por arma de fogo, foi admitido na UTI no 1º dia de pós-operatório de enterectomia, após aspiração de conteúdo gástrico durante reintubação traqueal. Evolução clínica: drogas vasoativas até o 4º dia de internação e broncopneumonia bilateral com derrame pleural e necessidade de ventilação artificial até o 15º dia. O esquema de sedação inicial utilizado foi a associação de midazolam e fentanil. A partir do 4º dia, o paciente apresentou vários episódios de agitação psicomotora, mesmo com a associação de lorazepam no 6° dia. No 9° dia, o paciente recebeu as maiores doses dos fármacos, mas permanecia agitado. Optou-se pela associação de dexmedetomidina, que reduziu as doses das outras drogas em 35% e diminuiu a agitação. No 12° dia, o midazolam e a dexmedetomidina foram substituídos pela infusão de propofol, com piora do quadro. No 13° dia, foi associada clonidina ao esquema de sedação, com resolução do quadro de agitação. No 14° dia, o propofol foi suspenso, sendo mantida a infusão de fentanil e reintroduzida a infusão de midazolam, com doses respectivamente 75% e 65% menores em relação ao pico de uso destas drogas. No 15° dia, o paciente foi extubado e teve alta da UTI. CONCLUSÕES: A droga de escolha para o tratamento da síndrome de abstinência alcoólica é o benzodiazepínico.

  5. Analytic neutrality, anonymity, abstinence, and elective self-disclosure.

    Shill, Merton A

    2004-01-01

    Recent contributions to the psychoanalytic literature propose new ways of understanding analytic neutrality, anonymity, abstinence, and self-disclosure. They advocate elective self-disclosure by the analyst as an antidote to the allegedly game-playing quality of transference and resistance analysis. The analytic relationship, they assert, becomes unreal when attempts are made to observe the principles of neutrality and abstinence. Both are seen as ill-conceived because of the irreducible subjectivity and unwarranted authority of the analyst. These relational and interactional views are criticized because (1) they ignore the fact that transference and resistance analysis have from Freud onward been accepted as minimal criteria qualifying a clinical process as psychoanalytic; (2) elective self-disclosure carries metapsychological implications dismissing not only Freud's theory of motivation but motivation as a basic feature of human personality; (3) they do not recognize interpersonal relations as mental events and so do not consider the ego's ability to create intrapsychic representations of object relations; (4) elective self-disclosures within the empathic parameters of the analytic situation are themselves unreal compared to the reality of the patient's experience with other objects. Abstinence and neutrality as ideals facilitate maintenance of an internal holding environment or container for the analyst's countertransference.

    Tolerance and dependence induced by chronic Δ-9-tetrahydrocannabinol (THC) administration were investigated in mice. The effects on body weight, analgesia and hypothermia were measured during 6 days of treatment (10 or 20 mg kg−1 THC twice daily). A rapid tolerance to the acute effects was observed from the second THC administration.The selective CB-1 receptor antagonist SR 141716A (10 mg kg−1) was administered at the end of the treatment, and somatic and vegetative manifestations of abstinence were evaluated. SR 141716A administration precipitated several somatic signs that included wet dog shakes, frontpaw tremor, ataxia, hunched posture, tremor, ptosis, piloerection, decreased locomotor activity and mastication, which can be interpreted as being part of a withdrawal syndrome.Brains were removed immediately after the behavioural measures and assayed for adenylyl cyclase activity. An increase in basal, forskolin and calcium/calmodulin stimulated adenylyl cyclase activities was specifically observed in the cerebellum of these mice.The motivational effects of THC administration and withdrawal were evaluated by using the place conditioning paradigm. No conditioned change in preference to withdrawal associated environment was observed. In contrast, a conditioned place aversion was produced by the repeated pairing of THC (20 mg kg−1), without observing place preference at any of the doses used.This study constitutes a clear behavioural and biochemical model of physical THC withdrawal with no motivational aversive consequences. This model permits an easy quantification of THC abstinence in mice and can be useful for the elucidation of the molecular mechanisms involved in cannabinoid dependence. PMID:9884086

Involved were auxiliaries, technicians and soon-to-be-nurses. The object was to evaluate the protocol´s potential as a guide to nursing care, and to test whether it was adequate in terms of comprehension and applicability. METHODS: A protocol based on the Clinical Institute Withdrawal Assessment was constructed to be applied by nursing professionals in hospitals and community clinics, allowing for possible alterations based upon individual patients. Fifty-nine workers tested the protocol over four months. RESULTS: Sixty-eight patients (21 women and 47 men, with average age between 34 and 40 years, were interviewed. Alcohol was the predominant drug of use (90% on a daily average between both sexes. The protocol was designed to systematize health care. Among its purposes were: to facilitate care (42.4%; provide a script for faster orientation (30.5%; provide information giving professional updates (25.4%; provide explanations regarding the particular sickness (23.7.

    There are many studies showing that more days of sexual abstinence increased sperm concentration, however, the direct influence between the days of abstinence and pregnancy rates has not been evaluated. The usual recommendation is 3-4 days prior to intrauterine insemination; this based on the interval that maximizes the number of motile sperm in the ejaculate. There are some reports with better success rate when abstinence is less than three days. To evaluate the pregnancy rate post-intrauterine insemination according to days of sexual abstinence prior to obtaining semen sample. A retrospective, observational and transversal study in patients attending the Mexican Center for Fertility (CEPAM) to intrauterine insemination. For analysis patients were grouped by age group, success rate and days of sexual abstinence. Continuous variables are reported as means and standard deviations; to determine statistical significance univariate logistic regression was performed. Categorical variables were evaluated in frequencies and percentages. The calculations were performed using JMP software program. 3,123 couples were included and increased success rate for intrauterine insemination was obtained with less than seven days of sexual abstinence. The rate of sperm retrieval is inversely proportional to the days of abstinence. A better pregnancy rate in intrauterine insemination was achieved with less than seven days of sexual abstinence and sperm retrieval rate was also recorded with fewer days of abstinence.

    Full Text Available States vary in standards for sex education, some requiring an emphasis on abstinence. Schools seek to identify curricula that reflect local community values and meet state standards. Choosing the Best (CTB, a classroom-based abstinence education curriculum, has been implemented in 75 Georgia school districts since 1995. CTB Inc., sought to determine if this popular program had an impact on abstinence attitudes, intentions, and behavior. Six Georgia public schools (1,143 ninth graders participated in the study in 2009-2010. Four randomly assigned schools received the CTB curriculum, taught by trained CTB staff. Two control schools received their usual textbook-based abstinence lessons. Surveys were conducted at the beginning and end of 9th grade, and the beginning of 10th grade. Data demonstrated significant impact of CTB at the end of 9th grade on commitment to abstinence, proabstinence beliefs and attitudes, intentions to maintain abstinence, and lower onset of sexual intercourse, and at the beginning of 10th grade on proabstinence attitudes. In two communities that sought an abstinence education approach, CTB had a short-term impact on abstinence attitudes, commitment, and behaviors, and a longer term impact on abstinence attitudes only.

  12. One month of cocaine abstinence potentiates rapid dopamine signaling in the nucleus accumbens core.

    Cocaine addiction is a chronic relapsing disorder that is difficult to treat in part because addicts relapse even after extended periods of abstinence. Given the importance of the mesolimbic dopamine (DA) system in drug addiction, we sought to characterize cocaine abstinence induced changes in rapid DA signaling in the nucleus accumbens (NAc). Here, rats were trained to self-administer cocaine for 14 consecutive days, then divided into two groups. Day 1 rats (D1; n = 7) underwent 24 h of abstinence; Day 30 rats (D30; n = 7) underwent one month of abstinence. After abstinence, all rats underwent a single extinction session. Immediately after, rats were deeply anesthetized and fast scan cyclic voltammetry (FSCV) was used to measure DA release and uptake dynamics in the NAc core before and following a single cocaine injection. We show that one month of cocaine abstinence potentiates the peak concentration of electrically evoked DA in the NAc core following an acute injection of cocaine. This potentiation is not related to alterations in DA uptake parameters, which are unchanged following abstinence, but may reflect alterations in release. These results further support the abundance of literature showing that cocaine abstinence induces neuroplasticity in brain areas implicated in drug reward and relapse. The present findings also demonstrate critical differences between abstinence-induced neuroadaptations in DA signaling and those caused by drug exposure itself. Copyright © 2016 Elsevier Ltd.

    Osteoprotegerin (OPG) is a parameter of increasing interest in the search for pathophysiological mechanisms of reduced bone mineral density (BMD). It has been shown to be increased in alcohol-dependent subjects. In our study, we wanted to examine whether changes in OPG and receptor activator of the nuclear factor-κB ligand (RANKL) levels during an 8-week abstinence period in alcohol-dependent patients treated in an alcohol rehabilitation clinic would occur and whether alcohol-related variables, smoking, status, or physical activity prior to the study served as an influence on BMD and on OPG/RANKL levels. Forty-three patients, who were abstinent not longer than a week, were included in the study. OPG and RANKL as well as other markers of bone metabolism were measured at baseline, and after 8 weeks of treatment, BMD was measured once. OPG levels decreased significantly, while osteocalcin, a marker of bone formation, increased significantly. RANKL as well as RANKL/OPG ratio, Serum CrossLaps, and all examined hormones showed no significant changes over time. Inflammatory parameters showed a significant reduction after 8 weeks. We detected no influence of potentially confounding variables of alcohol dependency on the course of OPG or other laboratory values. Our results could point to the well-known risk for reduced BMD in these patients being reversible with abstinence through an excess of bone formation. We also confirmed earlier findings that inflammatory processes play a role in the pathogenesis of alcohol-induced disturbances in bone metabolism.

    The object of this study is to evaluate the educational effects of group work sessions on drug dependence abstinence for convicts in Fukui Prison. Questionnaire surveys were conducted among participants on the first and last session. The results of surveys were analyzed quantitatively. The average ages of 50 respondents were 39 years. 95.9% of them used methamphetamine among drugs and the majority has used drugs for the past 5 years. 93.9% of respondents had no medical treatment histories and 95.8% of them have not used any formal consultations. The survey result before the sessions showed that 75.5% of respondents showed positive stances towards participations on educational group work sessions. The survey after the sessions showed 67.4% of respondents were able to talk their drug problems in group meetings and 87.0% responded that group work sessions were helpful for solving drug problems. Also, 80.0% responded that they can stop using drugs and the percentage dropped by 11.0% from the first session. In terms of the participation in self-help groups after releases from the prison, the majority responded negatively, although 78.0% showed positive responses to using consultation services. The outcomes by means of evaluation scale also showed a significant improvement on denial and no relevant change on interpersonal trusts. This study revealed that it was possible to confirm the effectiveness of drug abstinence education through group work. It is important to consider three points in further studies; 1) cooperation between judicial and medical institutions for introducing consultation and medical treatments among convicts; 2) follow-up programs for reinforcing education on drug abstinence; 3) social welfare services in cooperation with educational effects to prevent repeated offences.

    Although evidence suggests that drug abusers exhibit biases when coding individual emotional facial expressions, little is known about how they process multiple expressions simultaneously. The present study evaluated the mean emotions perceived by abstinent heroin abusers. Male abstinent heroin abusers (AHs) and healthy controls (HCs) were randomly assigned into three emotional conditions (happy, sad, or angry), viewed sets of four faces (Experiment 1) or individual faces (Experiment 2) that varied in emotionality (neutral to happy/sad/angry), and judged whether a test face presented later was more/less emotional than the preceding stimuli. Average points of subjective equality were calculated to reflect participants' biases in perceiving emotions of sets or single faces. Relative to HCs, AHs overestimated mean emotions for sad and angry faces in Experiment 1; however, no such biases were found in Experiment 2. This suggests biased ensemble coding towards negative emotional facial expressions in AHs. Furthermore, when controlling for depression and anxiety, AHs' enhanced perception of mean emotion for angry or sad faces in Experiment 1 decreased, indicating a possible mediating effect of these psychopathological variables in the relationship between drug addiction history and abnormal ensemble processing for sets of emotional expressions.

    The aim of this study was to examine whether caffeine abstinence in the evening could improve the sleep quality of those who habitually consume coffee. A double-blind control group design (caffeine and caffeine-free groups). A university. A convenience sampling of 10 students (mean age 21.4 years). It was a 14-day experiment. For the first 7 days, all participants consumed caffeinated coffee. In the following 7 days, subjects consumed caffeinated or decaffeinated coffee according to their assigned group. Sleep-wake parameters, self-reported sleep quality and level of refreshment. There were no significant differences (p>.05) among the data of the two groups identified. No significant changes (p>.05) were found in the sleep quality of either group during the study. This study confirms that caffeine abstinence in the evening might not be helpful in sleep promotion. It highlights the need to implement evidence-based practice in health promotion. Copyright © 2013 Elsevier Inc. All rights reserved.

    We sought to identify behavioral factors associated with response to an employment-based intervention, in which participants had to provide drug-free urine samples to gain access to paid employment. The present secondary analysis included data from a randomized clinical trial. The trial evaluated whether employment-based reinforcement could decrease cocaine use in community methadone patients. Participants (N=56) in the trial worked in a model workplace for 4 hr every weekday and earned about $10 per hr. After a 4-week baseline, participants were randomly assigned to an Abstinence & Work (n = 28) or Work Only (n = 28) condition and could work for an additional 26 weeks. Abstinence & Work participants had to provide cocaine-negative urine samples to work and maintain maximum pay. Work Only participants only had to work to earn pay. For Work Only participants, cocaine abstinence during baseline and the intervention period were significantly ( r s = .72, p workplace attendance was marginally correlated ( r s = .32, p = .098) with cocaine abstinence during the intervention period. Furthermore, participants who provided over 60% cocaine-negative urine samples during the intervention period (i.e., responders) had significantly higher baseline rates of opiate abstinence ( p workplace attendance ( p = .042) than non-responders. Employment-based reinforcement of cocaine abstinence may be improved by increasing opiate abstinence and workplace attendance prior to initiating the cocaine-abstinence intervention.

    This review begins with a comprehensive history of opioid dependence and treatment in the United States. The focus is an evidence-based treatment model for opioid/opiate dependent individuals. The role of reward genetic polymorphisms and the epigenetic modifications that lead to vulnerability to use and misuse of opiates/opioid to treat pain are reviewed. The neurochemical mechanisms of acute opiate withdrawal and opiate/opioid reward mechanisms are explored with a goal of identifying specific treatment targets. Alterations in functional brain connectivity based on neurobiological mechanisms in heroin dependence and abstinence are also reviewed. A new clinical model an alternative to merely blocking acute withdrawal symptoms as identified in the DSM -5 is proposed. Genetic diagnosis at the onset of detoxification, to determine risk stratification, and identify polymorphic gene targets for pharmaceutical and nutraceutical interventions, followed by the simultaneous initiation of Medication Assisted Therapy (MAT), to enable psychological extinction, and steady pro-dopaminergic therapy with the goal of developing "dopamine homeostasis" is recommended. The objective of these interventions is to prevent future relapse by treating all "Reward Deficiency Syndrome" (RDS) behaviors and eventually make an addiction-free life possible .

    Most individuals who enter drug treatment programs are unable to maintain long-term abstinence. This problem is especially relevant for those presenting with Antisocial Personality Disorder (ASPD). In examining potential mechanisms underlying the relationship between ASPD and abstinence, one factor that may be especially useful is the personality variable of impulsivity. Thus, the current study examined ASPD status in relation to longest abstinence attempt among 117 substance use treatment-seeking individuals, considering the mediating role of five facets of impulsivity: urgency, perseverance, premeditation, control, and delay discounting. Results indicated that individuals with ASPD evidenced shorter previous abstinence attempts and lower levels of perseverance and control than those without ASPD. Further, lower levels of control were associated with shorter abstinence attempts. Finally, control mediated the relationship between ASPD and longest quit attempt. These results suggest the potential value of multiple facets of impulsivity in efforts to understand relapse and subsequent treatment development efforts. Copyright © 2011 Elsevier Ltd.

    Abstinence for most adolescent-aged college students relates to several factors, including strong religious beliefs, an aversion to taking risks, high career expectations, or limited attractiveness. Young adults receive hundreds of messages from various sources; therefore, understanding their memorable sexual messages is essential. This exploratory research uses an interpretive method to unravel the memorable sexual narratives of 65 virgin respondents. Findings yield two primary themes: involuntary abstinence, and conscious abstinence, which demonstrate that messages of abstinence are important yet often imbue punitive internal attitudes and beliefs derived from mainstream media and peer relationships. The article concludes with a recommendation for health practitioners and communication scholars to create positive open spaces where young adults can discuss sexuality, sexual relationships, and sexual behaviors. Additionally, understanding stigmas related to abstinence helps reframe normative sex communication messages and promote constructive short- and long-term sexual health behaviors.

    We recently introduced an animal model of incubation of methamphetamine craving after choice-based voluntary abstinence in male rats. Here we studied the generality of this phenomenon to (1) female rats, and (2) male and female rats with a history of heroin self-administration. We first trained rats to self-administer palatable food pellets for 6 days (6 h per day) for either methamphetamine (0.1 mg/kg/infusion) or heroin (0.1 mg/kg/infusion) for 12 days (6 h/day). We then assessed relapse to drug seeking under extinction conditions after 1 and 21 abstinence days. Between tests, the rats underwent either voluntary abstinence (achieved via a discrete choice procedure between drug and palatable food; 20 trials/day) or home-cage forced abstinence. We found no sex differences in methamphetamine self-administration or in the strong preference for the palatable food over methamphetamine during the choice-based voluntary abstinence. In both sexes, methamphetamine seeking in the relapse tests was higher after 21 days of either voluntary or forced abstinence than after 1 day (incubation of methamphetamine craving). We also found no sex differences in heroin self-administration or the strong preference for the palatable food over heroin during the choice-based voluntary abstinence. However, male and female rats with a history of heroin self-administration showed incubation of heroin craving after forced but not voluntary abstinence. Our results show that incubation of methamphetamine craving after voluntary abstinence generalizes to female rats. Unexpectedly, prolonged voluntary abstinence prevented the emergence of incubation of heroin craving in both sexes.

    To examine whether initial orienting (IO) and inability to disengage (ITD) attention from negative affective stimuli moderate the association of negative affect with smoking abstinence during a quit attempt. Data were from a longitudinal cohort study of smoking cessation (N = 424). A negative affect modified Stroop task was administered 1 week before and on quit day to measure IO and ITD. Ecological Momentary Assessments were used to create negative affect intercepts and linear slopes for the week before quitting and on quit day. Quit day and long-term abstinence measures were collected. Continuation ratio logit model analyses found significant interactions for prequit negative affect slope with prequit ITD, odds ratio (OR) = 0.738 (0.57, 0.96), p = .02, and for quit day negative affect intercept with quit day ITD, OR = 0.62 (0.41, 950), p = .03, predicting abstinence. The Prequit Negative Affect Intercept × Prequit IO interaction predicting quit day abstinence was significant, OR = 1.42 (1.06, 1.90), p = .02, as was the Quit Day Negative Affect Slope × Quit Day IO interaction predicting long-term abstinence, OR = 1.45 (1.02, 2.08), p = .04. The hypothesis that the association of negative affect with smoking abstinence would be moderated by ITD was generally supported. Among individuals with high ITD, negative affect was inversely related to abstinence, but unrelated to abstinence among individuals with lower levels of ITD. Unexpectedly, among individuals with low IO, negative affect was inversely related to abstinence, but unrelated to abstinence among individuals with higher levels of ITD.

  8. NAS Panel faults export controls

    Katzoff, Judith A.

    A study prepared by a top-level panel says that current export controls on militarily sensitive U.S. technology may be “overcorrecting” previous weaknesses in that system, resulting in “a complex and confusing control system” that makes it more difficult for U.S. businesses to compete in international markets. Moreover, this control system has “an increasingly corrosive effect” on U.S. relations with allies. The panel recommended that the United States concentrate more effort on bringing about uniformity in the export control policies of countries belonging to the Coordinating Committee on Multilateral Export Controls (CoCom), i.e., most of the member nations in NATO (the North Atlantic Treaty Organization) and Japan.The 21-member panel was appointed by the Committee on Science, Engineering, and Public Policy (COSEPUP), a joint unit of the National Academy of Sciences (NAS), the National Academy of Engineering (NAE), and the Institute of Medicine (IOM). The panel, composed of administrators, researchers, and former government officials, was chaired by AGU member Lew Allen, Jr., director of the Jet Propulsion Laboratory (Pasadena, Calif.) and former chief of staff of the U.S. Air Force. Their report was supported by NAS funds, by a number of private organizations (including AGU), by the U.S. Departments of Commerce, Defense, Energy, and State, by the National Science Foundation, and by the National Aeronautics and Space Administration.

  10. Alcohol and pregnancy: do abstinence policies have unintended consequences?

    2012-01-01

    Most policies and guidelines recommend that women abstain from alcohol during pregnancy. This can be difficult to achieve in developed nations where the majority of women consume alcohol and almost half of pregnancies are unplanned, leading to many pregnancies being exposed to alcohol prior to pregnancy awareness. Concerns have been raised that abstinence policies may lead women in this situation to terminate their pregnancy out of fear that they have harmed their baby; however, the evidence is limited. A recent study found that while few women reported alcohol as the reason for seeking an abortion, in almost all cases where alcohol was the reason, the women were either binge drinking or reported alcohol-related problems and the pregnancy was unplanned.

    Cocaine is now responsible for the second-highest number of cessation intervention requests. In this study we analyze the different skills of emotional intelligence in cocaine- dependent patients maintaining abstinence. The Mayer- Salovey-Caruso Emotional Intelligence Test (MSCEIT) and the Balloon Analogue Risk Task (BART) were administered to 50 subjects (25 individuals with no history of drug use and 25 individuals in treatment at the Addictive Behaviors Unit in a state of withdrawal at the time of evaluation). The results showed differences between these groups in overall emotional intelligence quotient, strategic emotional intelligence, understanding emotions and emotional management. Cocaine-addicted participants showed difficulties in analyzing complex emotions and regulating their emotional response, aspects that can interfere with interactions in daily life.

    The need to fly UAS in the NAS to perform missions of vital importance to national security and defense, emergency management, science, and to enable commercial applications has been continually increasing over the past few years. To address this need, the NASA Aeronautics Research Mission Directorate (ARMD) Integrated Aviation Systems Program (IASP) formulated and funded the Unmanned Aircraft Systems (UAS) Integration in the National Airspace System (NAS) Project (hereafter referred to as UAS-NAS Project) from 2011 to 2016. The UAS-NAS Project identified the following need statement: The UAS community needs routine access to the global airspace for all classes of UAS. The Project identified the following goal: To provide research findings to reduce technical barriers associated with integrating UAS into the NAS utilizing integrated system level tests in a relevant environment. This report provides a summary of the collaborations between the UAS-NAS Project and its primary stakeholders and how the Project applied and incorporated the feedback.

    Full Text Available BACKGROUND: Abstinence-plus (comprehensive interventions promote sexual abstinence as the best means of preventing HIV, but also encourage condom use and other safer-sex practices. Some critics of abstinence-plus programs have suggested that promoting safer sex along with abstinence may undermine abstinence messages or confuse program participants; conversely, others have suggested that promoting abstinence might undermine safer-sex messages. We conducted a systematic review to investigate the effectiveness of abstinence-plus interventions for HIV prevention among any participants in high-income countries as defined by the World Bank. METHODS AND FINDINGS: Cochrane Collaboration systematic review methods were used. We included randomized and quasi-randomized controlled trials of abstinence-plus programs for HIV prevention among any participants in any high-income country; trials were included if they reported behavioural or biological outcomes. We searched 30 electronic databases without linguistic or geographical restrictions to February 2007, in addition to contacting experts, hand-searching conference abstracts, and cross-referencing papers. After screening 20,070 abstracts and 325 full published and unpublished papers, we included 39 trials that included approximately 37,724 North American youth. Programs were based in schools (10, community facilities (24, both schools and community facilities (2, health care facilities (2, and family homes (1. Control groups varied. All outcomes were self-reported. Quantitative synthesis was not possible because of heterogeneity across trials in programs and evaluation designs. Results suggested that many abstinence-plus programs can reduce HIV risk as indicated by self-reported sexual behaviours. Of 39 trials, 23 found a protective program effect on at least one sexual behaviour, including abstinence, condom use, and unprotected sex (baseline n = 19,819. No trial found adverse program effects on any

    Addiction is a chronic brain disorder. Prolonged abstinence from drugs of abuse involves dysphoria, high stress responsiveness and craving. The neurobiology of drug abstinence, however, is poorly understood. We previously identified a unique set of hundred mu-opioid receptor-dependent genes in the extended amygdala, a key site for hedonic and stress processing in the brain. Here we examined these candidate genes either immediately after chronic morphine, nicotine, Δ9-tetrahydrocannabinol or alcohol, or following 4 weeks of abstinence. Regulation patterns strongly differed among chronic groups. In contrast, gene regulations strikingly converged in the abstinent groups and revealed unforeseen common adaptations within a novel huntingtin-centered molecular network previously unreported in addiction research. This study demonstrates that, regardless the drug, a specific set of transcriptional regulations develops in the abstinent brain, which possibly contributes to the negative affect characterizing protracted abstinence. This transcriptional signature may represent a hallmark of drug abstinence and a unitary adaptive molecular mechanism in substance abuse disorders. © 2011 The Authors, Addiction Biology © 2011 Society for the Study of Addiction.

    Standard smoking cessation treatment studies have been limited to 6- to 12-month follow-up, and examination of predictors of abstinence has been restricted to this timeframe. The KanQuit study enrolled 750 rural smokers across all stages of readiness to stop smoking and provided pharmacotherapy management and/or disease management, including motivational interviewing (MI) counseling every 6 months over 2 years. This paper examines differences in predictors of abstinence following initial (6-month) and extended (24-month) intervention. Baseline variables were analyzed as potential predictors of self-reported smoking abstinence at Month 6 and at Month 24. Chi-square tests, 2-sample t tests, and multiple logistic regression analyses were used to identify predictors of abstinence among 592 participants who completed assessment at baseline and Months 6 and 24. Controlling for treatment group, the final regression models showed that male gender and lower baseline cigarettes per day predicted abstinence at both 6 and 24 months. While remaining significant, the relative advantage of being male decreased over time. Global motivation to stop smoking, controlled motivation, and self-efficacy predicted abstinence at 6 months but did not predict abstinence at Month 24. In contrast, stage of change was strongly predictive of 24-month smoking status. While the importance of some predictors of successful smoking cessation appeared to diminish over time, initial lack of interest in cessation and number of cigarettes per day strongly predicted continued smoking following a 2-year program.

    Alcohol use is a major public health concern with respect to its impact on youth morbidity and mortality. Self-efficacy to abstain from alcohol use in young people is an important prevention and intervention strategy in future alcohol dependence. However, research on the assessment of self-efficacy to abstain from alcohol use among undergraduate students is almost non-existent in Ghana, apparently due to the unavailability of a standardised testing instrument. The purpose of this study was to examine the factor validity, structure, and reliability of the 20-item Alcohol Abstinence Self-efficacy Scale (AASES) in undergraduate students in Ghana. Two hundred and fifteen undergraduate students studying in a private university with a mean age of 23.5 years participated in the study by completing the AASES. Results of a confirmatory factor analysis showed that the data did not fit the initial four-factor AASES model. Subsequent exploratory factor analysis showed that the AASES is a unidimensional construct (in the total sample and a subsample of drinkers), contrary to findings found in western cultures. The AASES also had a high Cronbach's alpha. Although the AASES was unidimensional in this study, each of the original four-factor model also had high and acceptable Cronbach's alpha. The original AASES structure was not confirmed in this study but a unidimensional factor was found suggesting that the AASES could be used as an instrument for assessing alcohol abstinence self-efficacy in undergraduate students in Ghana, although further validation research is needed in larger as well as in different samples.

    The experiment was designed to investigate the variation of DAT and D2 receptor in morphine administered and 1,2,3 day abstinent rats. Morphine exposure was induced by repeated morphine (i.p.) treatment for 8 days. Conditioned place preference test was conducted to evaluate the drug seeking behaviour and morphine dependence of rats with morphine exposure. Biodistribution of the imaging agents 125 I-β-CIT and 125 I-IBZM was used to evaluate the central DAT and D2 receptor during morphine exposure and 1,2,3 day's abstinence. Results reveal the following facts. (1) The morphine abstinent rats showed diarrhea and body-shake 1 day after morphine withdrawal. (2) For morphine group, 125 I-β-CIT %ID/g in ST and NAC was higher than that of the 1,2,3 day's abstinent rats and control (P 0.05). (3) 125 I-IBZM %ID/g in ST, NAC and HIP in morphine rats were lower than those of the abstinent and control rats (P 125 I-IBZM %ID/g in ST and NAC gradually increased with the abstinent days. While in ST the %ID/g among the abstinent rats was all lower than that of the control rats, in NAC the %ID/g was still lower in 1 day's abstinent rats (P 0.05), indicating the reduction of hyper-activated DAT and the increase of down-regulatory D2 receptor induced by morphine during morphine withdrawal. Our results confirmed that the dopamine system, especially DAT and D2 receptor in mesolimbic and meso-striatum pathway, has been implicated in morphine treatment. The rewarding properties of morphine and the somatic expression of morphine abstinence were related to changes in mesolimbic and meso-striatum dopaminergic activity. (authors)

    We examined whether cocaine-dependent homeless persons had stable housing and were employed 6, 12, and 18 months after they entered a randomized controlled trial comparing 2 treatments. One group (n = 103) received abstinence-contingent housing, vocational training, and work; another group (n = 103) received the same intervention plus cognitive behavioral day treatment. We examined baseline and early treatment variables for association with long-term housing and employment. Although the enhanced-treatment group achieved better abstinence rates, the groups did not differ in long-term housing and employment stability. However, consecutive weeks of abstinence during treatment (and to a lesser extent, older age and male gender) predicted long-term housing and employment stability after adjustment for baseline differences in employment, housing, and treatment. Our data showed a relationship of abstinence with housing stability. Contrasting these results with the increasingly popular Housing First interventions reveals important gaps in our knowledge to be addressed in future research.

  6. Visual P300s in long-term abstinent chronic alcoholics.

    Evidence of reduced P3b amplitudes in chronic alcoholics and individuals at risk for developing alcoholism suggest that the P3b may be an endophenotypic marker for alcoholism. If this is the case, then long-term abstinent alcoholics (LTAAs) should exhibit reduced P3b amplitudes. Thus far, P3b studies on chronic alcoholics have focused primarily on samples with relatively short-term abstinence (less than 15 months). This study examines the amplitude and latency of the P3b and P3a event-related brain electrical components in LTAAs compared with normal controls (NCs) and whether these measures are related to alcohol use and other subject variables. Electroencephalographs (EEGs) were recorded on 48 LTAAs (mean abstinence=6.7 years) compared with 48 age-matched and gender-matched NCs during a visual P300 experiment consisting of standard, target, and rare nontarget conditions. This paradigm elicited the P3b (target condition) and the P3a (rare nontarget condition) components. Long-term abstinent alcoholics had reduced P3b amplitudes and increased P3b latencies in comparison with NCs. Long-term abstinent alcoholics also exhibited delayed P3a components, but no P3a amplitude reductions. Alcohol use variables, a family history of alcohol problems, and the duration of alcohol abstinence were not associated with any amplitude or latency variables. Even after very prolonged abstinence, reduced P3b amplitudes are present in chronic alcoholics and are not associated with any family history or alcohol use variables. These results provide equivocal support for reduced P3b amplitude being an endophenotypic marker for alcoholism, but are also consistent with P3b being affected by a threshold of alcohol abuse, with the effect not resolving over long periods of abstinence.

    The aim of the present study is to review the effects of caffeine abstinence on the quality of sleep. Insomnia is a common problem and abstinence from caffeine is the most popular component in sleep hygiene advice. However, there have been inconsistent results relating to the effectiveness of caffeine abstinence in improving sleep. Systematic review. We browsed several electronic databases and reference lists of articles about the correlation of caffeine consumption and sleep deprivation. We selected the articles according to predefined inclusion and exclusion criteria. Two reviewers assessed the quality of trials, which were selected according to the Jadad quality assessment scale. We included the trials scoring three or above in the systematic review and extracted their data. We assessed the heterogeneity of the studies before we considered whether or not to combine the studies' results. Three randomised control trials fulfilled the selection criteria among which two trials scored > or =3 on the Jadad scale. We included these two trials in our systematic review. The designs and outcome measurements of these two trials were not homogeneous, therefore, we did not combine their results. Instead, we conducted a critical appraisal. In one trial, caffeine abstinence was associated with significant lengthening of sleep duration (p sleep quality (p caffeine abstinence for a whole day could improve sleep quality. Thus, health practitioners were recommended to include caffeine abstinence in the instructions for sleep hygiene.

    of high-sensitivity cardiac troponin I (hs-cTnI, compared with conventional cardiac troponin T (cTnT in the setting of non-ST elevation acute coronary syndromes. METHODS: At hospital admission, a plasma sample was collected from 103 consecutive patients with unstable angina or non-ST elevation acute myocardial infarction. In this sample, troponin was measured both by hs-cTnI and cTnT methods. Their prognostic value was compared as to the occurrence of major cardiovascular events, defined as a combination of death, nonfatal acute myocardial infarction or refractory unstable angina during hospitalization. RESULTS: During median hospitalization of 8 days (interquartile range = 5 - 11, the incidence of cardiovascular events was 10% (5 deaths, 3 non-fatal myocardial infarctions and 2 non-fatal refractory anginas. High-sensitivity troponin I significantly predicted cardiovascular events, with a C-statistics of 0.73 (95% CI = 0.59 - 0.87, similarly to cTnT (0.70; 95% CI = 0.55 - 0.84 - P = 0.75. The definition of positive cardiac marker that provided the best prognostic accuracy was hs-cTnI > 0.055 µg/L and cTnT > 0.010 µg/L, with equal sensitivity of 90% and specificity of 52% for both assays. Positive hs-cTnI was associated with 17% incidence of events, compared with 2% in patients with negative hs-cTnI (P = 0.02. CONCLUSION: High-sensitivity troponin I predicts cardiovascular events similarly to conventional troponin T in the setting of non-ST-elevation ACS.

    The key problem in treating cocaine addiction is the maintenance of a drug-free state as negative emotional symptoms during abstinence often trigger relapse. The mechanisms underpinning the emotional dysregulation during abstinence are currently not well-understood. There is evidence suggesting a role of the neuropeptide oxytocin in the modulation of drug addiction processes. However, its involvement during long-term abstinence from cocaine use remains unclear. In this study, we aimed to behaviourally characterize a mouse model of long-term cocaine withdrawal and assess the effect of chronic cocaine administration and long-term cocaine abstinence on the central oxytocinergic system and the hypothalamic-pituitary-adrenal axis. Fourteen-day escalating-dose cocaine administration (3 × 15-30 mg/kg/day) and 14-day withdrawal increased plasma corticosterone levels and oxytocin receptor (OTR) binding in piriform cortex, lateral septum and amygdala. A specific cocaine withdrawal-induced increase in OTR binding was observed in the medial septum. These biochemical alterations occurred concomitantly with the emergence of memory impairment, contextual psychomotor sensitization and an anhedonic and anxiogenic phenotype during withdrawal. Our study established a clear relationship between cocaine abstinence and emotional impairment in a novel translationally relevant model of cocaine withdrawal and demonstrated for the first time brain region-specific neuroadaptations of the oxytocin system, which may contribute to abstinence-induced negative emotional state. © 2016 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    Full Text Available Our research aims to find out if there is a difference between women voters and abstinents in Bosnia and Herzegovina, considering certain socio-psychological characteristics. For the purpose of this research we used Likert scales to measure: tolerance to other ideas, nationalism, ethical superiority, attitude towards leader, conformism, liberalism/conservativism and locus of control. This research was con-ducted in May 2007 on the sample of 547 women voters and 214 women abstinents. Results show that socio-demographic characteristics differ potential women voters from women abstinents. Women who are more active (educated, employed or mem-bers of some political party in their everyday life are more likely to go to the electi-ons and vote. Discriminative analysis showed that women voters and abstinents significantly differed at four of total seven variables. The difference between women voters and abstinents is in ethical superiority, acceptance of nationalism, tolerance to other ideas and attitude towards leader. Therefore it seems that women abstinents have greater democratic potential than women voters.

    Direct and mediated associations between subjective social status (SSS), a subjective measure of socio-economic status, and smoking abstinence were examined during the period of acute withdrawal among a diverse sample of 421 smokers (33% Caucasian, 34% African American, 33% Latino) undergoing a quit attempt. Logistic regressions examined relations between SSS and abstinence, controlling for socio-demographic variables. Depression, stress, positive affect and negative affect on the quit day were examined as potential affective mediators of the SSS-abstinence association, with and without adjusting for pre-quit mediator scores. SSS predicted abstinence to 2 weeks post-quit. Abstinence rates were 2.6 (postquit week 1) and 2.4 (postquit week 2) times higher in the highest versus the lowest SSS quartile. Depression and positive affect mediated the SSS-abstinence relationships, but only depression maintained significance when adjusting for the baseline mediator score. Among a diverse sample of quitting smokers, low SSS predicted relapse during acute withdrawal after controlling for numerous covariates, an effect accounted for partially by quit day affective symptomatology. Smokers endorsing lower SSS face significant hurdles in achieving cessation, highlighting the need for targeted interventions encompassing attention to quit day mood reactivity.

    Full Text Available Background. There are no studies in South Africa (SA on the outcomes following detoxification and psychosocial rehabilitation of heroin-dependent patients. Objective. To compare the demographic, clinical, forensic and treatment data of active heroin users v. users who were abstinent at the time of interview 4 years after attending the Opioid Detoxification Unit at Stikland Hospital in the Western Cape Province, SA.  Method. Participants included patients above the age of 16 years who had been admitted to the Opioid Detoxification Unit at Stikland Hospital for heroin detoxification between July 2006 and June 2007. Participants were individually interviewed (either in person or tele­phonically using a structured self-report questionnaire to collect demographic, clinical, forensic and treatment data 4 years following heroin detoxification treatment at this unit.  Results. Of the participants, 60% were abstinent and a large portion (34% attributed this to social support. Furthermore, there was a significant (p=0.04 difference in the longest period of abstinence between the past user group and active users, with more participants in the past user group being abstinent for 18 months or longer (n=24, 57% than in the active users group (n=8, 29%. Active users (n=18, 64% had significantly (p=0.03 more legal problems than abstinent users (n=14, 33%. Most participants (n=38, 54% relapsed within 3 months after index detoxification and rehabilitation.  Conclusion. Active users had more legal problems than abstinent users, with social support structures playing a pivotal role in abstinence. Future research should assess the impact of interventions such as post-discharge social support programmes on criminality and heroin use in those that relapse following treatment.

    Evidence indicates that the brain nicotinic acetylcholine receptor (nAChRs) ligand lobeline reduces depression-like behaviors, ethanol drinking, and nicotine withdrawal-induced depression-like behaviors. The purpose of the present study was to determine the effects of lobeline on ethanol abstinence-induced depression-like behavior and associated neuroadaptive changes in mice. Adult C57BL/6J male mice were allowed to drink 10% ethanol for 4 weeks using a two-bottle choice procedure. Mice were tested after 24 h and 14 days of ethanol abstinence in a forced swim test (FST), a measure for depression-like behavior. Acute lobeline treatment (1 mg/kg) significantly reduced immobility time compared to controls after 24 h and 14 days of abstinence. In addition, abstinence from chronic ethanol exposure reduced serotonin levels in the hippocampus, which was reversed by acute lobeline treatment. Repeated lobeline treatment (1 mg/kg, once daily) for 14 days during ethanol abstinence also significantly reduced FST immobility in mice exposed to ethanol. Chronic ethanol exposure significantly reduced the number of 5-bromo 2'-deoxyuridine (BrdU)-positive cells in the dentate gyrus of the hippocampus, indicating decreased hippocampal cell proliferation. Abstinence from chronic ethanol exposure also decreased brain-derived neurotrophic factor (BDNF) in the dentate gyrus and CA3 region of the hippocampus. In contrast, repeated lobeline treatment significantly increased both BrdU- and BDNF-positive cells. Taken together, our results indicate that lobeline produced antidepressant-like effects, likely by targeting brain β2-containing nAChRs, serotonergic neurotransmission, and/or hippocampal cell proliferation. Therefore, lobeline may have therapeutic utility to treat alcohol abstinence-induced depression. Copyright © 2017 Elsevier Inc. All rights reserved.

    Despite the critical role of withdrawal, craving, and positive affect (PA) and negative affect (NA) in smoking relapse, relatively little is known about the temporal and predictive relationship between these constructs within the first day of abstinence. This pilot study aims to characterize dynamic changes in withdrawal, craving, and affect over the course of early abstinence using ecological momentary assessment. Beginning immediately after smoking, moderate and heavy smoking participants (n = 15 per group) responded to hourly surveys assessing craving, withdrawal, NA, and PA. Univariate and multivariate multilevel random coefficient modeling was used to describe the progression of craving, withdrawal/NA, and PA and to test correlations between these constructs at the subject level over the course of early abstinence. Heavy smokers reported greater craving from 1-4 hr of abstinence and greater withdrawal/NA after 3 or more hours as compared with moderate smokers. Level of withdrawal/NA was strongly positively associated with craving, and PA was negatively correlated with craving; however, the temporal dynamics of these correlations differed substantially. The association between withdrawal/NA and craving decreased over early abstinence, whereas the reverse was observed for PA. These findings can inform experimental studies of nicotine abstinence as well as their clinical applications to smoking cessation efforts. In particular, these results help to elucidate the role of PA in nicotine abstinence by demonstrating its independent association with nicotine craving over and above withdrawal/NA. If supported by future studies, these findings can refine experimental methods and clinical approaches for smoking cessation. (c) 2015 APA, all rights reserved).

    Interactions of large-scale brain networks may underlie cognitive dysfunctions in psychiatric and addictive disorders. To test the hypothesis that the strength of coupling among 3 large-scale brain networks--salience, executive control, and default mode--will reflect the state of nicotine withdrawal (vs smoking satiety) and will predict abstinence-induced craving and cognitive deficits and to develop a resource allocation index (RAI) that reflects the combined strength of interactions among the 3 large-scale networks. A within-subject functional magnetic resonance imaging study in an academic medical center compared resting-state functional connectivity coherence strength after 24 hours of abstinence and after smoking satiety. We examined the relationship of abstinence-induced changes in the RAI with alterations in subjective, behavioral, and neural functions. We included 37 healthy smoking volunteers, aged 19 to 61 years, for analyses. Twenty-four hours of abstinence vs smoking satiety. Inter-network connectivity strength (primary) and the relationship with subjective, behavioral, and neural measures of nicotine withdrawal during abstinence vs smoking satiety states (secondary). The RAI was significantly lower in the abstinent compared with the smoking satiety states (left RAI, P = .002; right RAI, P = .04), suggesting weaker inhibition between the default mode and salience networks. Weaker inter-network connectivity (reduced RAI) predicted abstinence-induced cravings to smoke (r = -0.59; P = .007) and less suppression of default mode activity during performance of a subsequent working memory task (ventromedial prefrontal cortex, r = -0.66, P = .003; posterior cingulate cortex, r = -0.65, P = .001). Alterations in coupling of the salience and default mode networks and the inability to disengage from the default mode network may be critical in cognitive/affective alterations that underlie nicotine dependence.

    In this study, new and feasible UV-visible spectrophotometric and multivariate spectrophotometric methods were described for the simultaneous determination of hydrochlorothiazide (HCTZ), hydralazine hydrochloride (H.HCl), and reserpine (RES) in combined pharmaceutical tablets. Methanol was used as a solvent for analysis and the whole UV region was scanned from 200-400 nm. The resolution was obtained by using multivariate methods such as the net analyte signal method (NAS), principal component analysis (PCA), and net analyte signal-principal component analysis (NAS-PCA) applied to the UV spectra of the mixture. The results obtained from all of the three methods were compared. NAS-PCA showed a lot of resolved data as compared to NAS and PCA. Thus, the NAS-PCA technique is a combination of NAS and PCA methods which is advantageous to obtain the information from overlapping results.

    We evaluated the effect of short-term and long-term heroin abstinence on brain responses to heroin-related cues using functional magnetic resonance imaging (fMRI). Eighteen male heroin addicts following short-term abstinence and 19 male heroin addicts following long-term abstinence underwent fMRI scanning while viewing heroin-related and neutral images. Cue-elicited craving and withdrawal symptoms in the subjects were measured. Following short-term abstinence, greater activation was found in response to heroin cues compared to neutral cues in bilateral temporal, occipital, posterior cingulate, anterior cingulate, thalamus, cerebellum, and left hippocampus. In contrast, activations in bilateral temporal and occipital and deactivations in bilateral frontal, bilateral parietal, left posterior cingulate, insula, thalamus, dorsal striatum, and bilateral cerebellum were observed following long-term abstinence. Direct comparisons between conditions showed greater brain reactivity in response to smoking cues following short-term abstinence. In addition, short-term abstinence had more serious withdrawal symptoms than the long-term. The present findings indicate that compared to short-term, long-term abstinence manifests less serious withdrawal symptoms and significantly decreases neural responses to heroin-related cues in brain regions subserving visual sensory processing, attention, memory, and action planning. These findings suggest that long-term abstinence can decrease the salience of conditioned cues, thereby reducing the risk of relapses. The study's limitations are noted.

    Many studies of cocaine-responsive gene expression have focused on changes occurring during cocaine exposure, but few studies have examined the persistence of these changes with cocaine abstinence. Persistent changes in gene expression, as well as alterations induced during abstinence may underlie long-lasting drug craving and relapse liability. Whole-genome expression analysis was conducted on a rat cocaine binge-abstinence model that has previously been demonstrated to engender increased drug seeking and taking with abstinence. Gene expression changes in two mesolimbic terminal fields (mPFC and NAc) were identified in a comparison of cocaine-naïve rats with rats after 10 days of cocaine self-administration followed by 1, 10, or 100 days of enforced abstinence (n = 6-11 per group). A total of 1,461 genes in the mPFC and 414 genes in the NAc were altered between at least two time points (ANOVA, p genes can be subdivided into: 1) changes with cocaine self-administration that do not persist into periods of abstinence, 2) changes with cocaine self-administration that persist with abstinence, 3) and those not changed with cocaine self-administration, but changed during enforced abstinence. qPCR analysis was conducted to confirm gene expression changes observed in the microarray analysis. Together, these changes help to illuminate processes and networks involved in abstinence-induced behaviors, including synaptic plasticity, MAPK signaling, and TNF signaling.

    Clinical trials with cocaine-dependent outpatients have found a strong relation between in-treatment and follow-up abstinence, and the strength of this relation is constant across treatment conditions with variable efficacy in generating abstinence. The authors conducted secondary analyses of data from 3 clinical trials to determine whether this relation generalizes to cocaine-dependent homeless persons. The 3 trials (total N = 543) were conducted in a community health care facility for homeless people. The 7 treatment arms across the 3 trials were combinations of day treatment, abstinence-contingent housing, and vocational training. Drug use was measured with urine toxicology testing. Consecutive weeks of abstinence during treatment were strongly related to abstinence at the 12-month follow-up, whether or not missing 12-month data were included in the analysis. The treatment arms differed in their efficacy in generating abstinence, but the relation between in-treatment and follow-up abstinence did not differ across treatment arms. These results replicate earlier reports of these relations and extend them to a population of homeless people. The lack of differences between treatment arms in the in-treatment-follow-up abstinence relation implies that that relation is independent of the treatment-specific intervention components that generate group differences in abstinence.

    As many as one-half of smokers relapse in the first week following a quit attempt, and subjective reports of cognitive deficits in early abstinence are associated with increased relapse risk. This study examined whether objective cognitive performance after three days of abstinence predicts smoking resumption in a 7-day simulated quit attempt. Sixty-seven treatment-seeking smokers received either varenicline or placebo (randomized double-blind) for 21 days. Following medication run-up (days 1-10), there was a 3-day mandatory (biochemically confirmed) abstinence period (days 11-13) during which working memory (Letter-N-Back Task) and sustained attention (Continuous Performance Task) were assessed (day 13). Participants were then exposed to a scheduled smoking lapse and instructed to try to remain abstinent for the next 7 days (days 15-21). Poorer cognitive performance (slower correct reaction time on Letter-N-Back task) during abstinence predicted more rapid smoking resumption among those receiving placebo (p=.038) but not among those receiving varenicline. These data lend further support for the growing recognition that cognitive deficits involving working memory are a core symptom of nicotine withdrawal and a potential target for the development of pharmacological and behavioral treatments.

  4. Cocaine abstinence following chronic treatment alters cerebral metabolism in dopaminergic reward regions. Bromocriptine enhances recovery

    2-[14C]deoxyglucose autoradiography was used to determine local cerebral glucose utilization (lCGU) in rats following chronic cocaine treatment and subsequent abstinence. lCGU was examined in 43 discrete brain regions in animals which had received daily injections of cocaine for 14 days (10 mg/kg) followed by 3 days of saline or bromocriptine (10 mg/kg) treatment. Cocaine abstinence following chronic treatment significantly reduced lCGU in several regions including mesocorticolimbic structures such as ventral tegmental area, medial prefrontal cortex, and nucleus accumbens (NAc). Within the NAc, however, only the rostral pole showed significant reduction. In contrast, when bromocriptine treatment accompanied abstinence, lCGU was no longer reduced in mesocorticolimbic and most other regions, implying that metabolic recovery was enhanced by bromocriptine treatment during early abstinence following chronic cocaine treatment. These data suggest that cerebral metabolism is decreased during cocaine abstinence following chronic treatment in critical brain regions, and that this alteration can be prevented by treatment with direct-acting dopamine agonists such as bromocriptine

    Full Text Available Alcohol use disorders (AUDs may be associated with several psychological and affective disorders. It is controversial, however, if these symptoms are a cause or rather a consequence of alcohol dependence. There are few data testing simultaneously psychosocial and affective disorders before and after a period of alcohol abstinence. The aim of this study was to perform multiple psychometric evaluations in alcohol-dependent patients before and after 12 weeks of abstinence. Twenty-five alcohol-dependent patients were included in the study. The following psychometric tests were administered at baseline (T0 and after 12 weeks (T1: Addiction Severity Index (ASI, Brief Psychiatric Rating Scale (BPRS, Social Behaviour Scale (SBS, Sheehan Disability Scale (DISS, Aggression Questionnaire (AQ. At T1, 16 (64% patients were abstinent, 5 (20% patients dropped out and 4 (16% patients relapsed. Compared to T0, patients totally abstinent at T1 showed a significant reduction of the scores related to BPRS, BPRS-E and its subscales (except BPRS 5, ASI 1, ASI 2, ASI 3, ASI 6, ASI 7, BSM, AQ, DISS 1, DISS 2, DISS 3 (p<0.05. No significant changes in ASI 4, ASI 5, DISS 4 and DISS 5, BPRS 5 scores were found at T1 compared to T0. The present study indicates that total alcohol abstinence improves psychometric features, such as alcohol addiction severity, psychiatric rating, social behaviour, aggressiveness, and disability. Larger controlled studies are needed to confirm these findings.

    It is unclear whether increasing the dose of varenicline beyond the standard dose of 2 mg/d would improve smoking abstinence. We examined the effect of 3 mg/d of varenicline on smoking abstinence among smokers who had reduced their smoking by 50% or more in response to 2 mg/d for at least 6 weeks but had not quit smoking. Of 2833 patients treated with varenicline, dosage of a subset of 73 smokers was increased to 3 mg/d after 6 weeks. We used a propensity score analysis involving multiple baseline covariates to create a comparative sample of 356 smokers who remained on 2 mg/d. All smokers received concurrent and similar smoking-cessation counseling. At 3 months, we found higher 7-day point prevalence smoking-abstinence rate in the 3-mg group (26%) than in the 2-mg group (11.5%, χ = 10.60, P < 0.001; risk ratio [RR], 2.3; 95% confidence interval [CI], 1.4-3.6). The difference in abstinence rates remained significant at the 6-month (P < 0.001; RR, 2.6; 95% CI, 1.6-3.9) and 9-month follow-up (P < 0.001; RR, 2.2; 95% CI, 1.4-3.3). A relatively small increase in the daily dose of varenicline seems to offer a benefit for those who are not able to achieve total abstinence after approximately 6 weeks of 2 mg/d.

    This pilot study tested the efficacy of a voluntary 84-hour abstinence protocol for modifying problematic Internet gaming cognitions and behaviors METHOD: Twenty-four adults from online gaming communities, including 9 individuals who screened positively for Internet gaming disorder (IGD), abstained from Internet games for 84 hours. Surveys were collected at baseline, at daily intervals during abstinence, and at 7-day and 28-day follow-up RESULTS: Brief voluntary abstinence was successful in reducing hours of gaming, maladaptive gaming cognitions, and IGD symptoms. Abstinence was highly acceptable to participants with total compliance and no study attrition. Clinically significant improvement in IGD symptoms occurred in 75% of the IGD group at 28-day follow-up. Reliable improvement in maladaptive gaming cognitions occurred in 63% of the IGD group, whose cognition score reduced by 50% and was comparable to the non-IGD group at 28-day follow-up CONCLUSIONS: Despite limitations of sample size, this study provides promising support for brief abstinence as a simple, practical, and cost-effective treatment technique for modifying unhelpful gaming cognitions and reducing Internet gaming problems. © 2017 Wiley Periodicals, Inc.

    Attentional biases have been recognized as factors responsible for the maintenance of gambling problems. To date, no study has ever assessed the attentional biases among problem gamblers that have discontinued gambling (e.g., abstinent gamblers in treatment). The sample consisted of 75 participants comprising three groups: non-problem gamblers, problem gamblers, and abstinent pathological gamblers undergoing treatment. The groups were discriminated using South Oaks Gambling Screen scores, with the exception of the abstinent pathological gamblers that already had a DSM-5 diagnosis for gambling disorder. Participants carried out a modified Posner Task for the assessment of attentional bias for gambling stimuli and completed the Depression Anxiety Stress Scale and the Gambling Craving Scale. Abstinent pathological gamblers showed an avoidance bias in the maintenance of attention, whereas problem gamblers exhibited a facilitation in detecting gambling stimuli. No biases were detected in non-problem gamblers. The results also demonstrated that compared to the other groups, abstinent pathological gamblers showed high emotional stress and problem gamblers reported a higher level of craving. The sample size limits the generalizability of results. The present study demonstrated that attentional biases affect the maintenance and the discontinuation of gambling activities, and that the subjective feeling of craving for gambling may facilitate problem gamblers' attention towards gambling stimuli.

Abstinence when practiced provides the most effective means in preventing these problems, yet the perspective of abstinent young women is not well understood. The purpose of the investigation was to characterize female adolescents’ motivations for abstinence. Method As part of a larger, cross-sectional quantitative study investigating predictors of HIV risk reduction behaviors, qualitative responses from study participants who never had intercourse were analyzed in a consensus-based process using content analysis and frequency counts. An urban primary care site in a tertiary care center served as the setting, with adolescent young women ages 15–19 years included in the sample. Results Five broad topic categories emerged from the data that characterized motivations for abstinence in this sample: 1) Personal Readiness, 2) Fear, 3) Beliefs and Values, 4) Partner Worthiness and 5) Lack of Opportunity. Discussion A better understanding of the motivations for abstinence may serve to guide the development of interventions to delay intercourse. PMID:22525893

    Sexual abstinence is often deemed the “safest behavior” in HIV prevention, but is sometimes associated with psychological symptoms (e.g., depression) just as sexually risky behavior is. This study explored whether sexual abstinence and risky sexual behavior among men with HIV are associated with similar constellations of psychological symptoms. Prior research has not addressed this issue because abstinent people often are not included in the sample, or when data are analyzed, researchers combine abstinent people with sexually active people who practice safer sex. Past research also neglects the co-morbidity of psychological symptoms. A latent class analysis of the psychological symptoms (assessed with the Symptom Check List 90-R; Derogatis, 1994) of 140 men with HIV, mostly from rural New England, revealed three latent classes; men who were asymptomatic on all symptom domains (28.8%), men who were symptomatic on all domains (34.1%), and men who were symptomatic on internalizing domains (37.1%), but were asymptomatic on the externalizing symptoms of hostility and paranoid ideation. Logistic regression showed that sexual behavior during the past 90 days of men in the all symptom class and the internalizing symptoms class was similar, with abstinence and risky sex predominating, and safer sex being relatively uncommon for both classes. The sexual behavior of men in the asymptomatic class differed, with safer sex being relatively more likely to occur compared to the symptomatic classes. These findings suggest that the psychological symptom profile of sexually abstinent people places them at risk for inconsistent condom use should they engage in sexual behavior. PMID:25614050

    To compare the effect of maintenance pharmacotherapy on sustained abstinence rates between recently abstinent smokers with schizophrenia and bipolar disorder (SBD) and general population smokers without psychiatric illness. We performed a person-level, pooled analysis of two randomized controlled trials of maintenance varenicline, conducted in adult smokers with SBD and general population smokers, controlling for severity of dependence. Smokers abstinent after 12-weeks of open varenicline treatment were randomly assigned to ≥12-weeks maintenance varenicline or identical placebo. In those assigned to maintenance placebo, the abstinence rate at week-24 was lower in those with SBD than for those without psychiatric illness (29.4±1.1% vs. 61.8±0.4%, OR:0.26, 95% CI: 0.13, 0.52, pmaintenance pharmacotherapy, however, there was no effect of diagnosis on abstinence rates at week-24 (87.2±0.8% vs. 81.9±0.2%, OR: 1.68, 95% CI: 0.53, 5.32, p=0.38). Time to first lapse was shortest in those with SBD assigned to maintenance placebo (Q1=12days, 95%CI: 4, 16), longer in those without psychiatric illness assigned to maintenance placebo (Q1=17days, 95%CI: 17, 29), still longer in general-population smokers assigned to maintenance varenicline (Q1=88, 95% CI:58,91, and longest in those with SBD who received maintenance varenicline (Q1>95days, 95%CI:non-est), (Χ 2 3df =96.99, pmaintenance varenicline treatment. Maintenance pharmacotherapy could improve longer-term tobacco abstinence rates and reduce known smoking-related health disparities in those with SMI. Copyright © 2016 The Authors.

    Although quitting motivation predicts smoking cessation, there have been inconsistent findings regarding motivation predicting long-term maintenance of abstinence. Moreover, most such research has been conducted in North America and the United Kingdom. The aim of this study was to examine motivation to quit as a predictor of smoking cessation and of abstinence maintenance in a Spanish sample. The sample comprised 286 Spanish smokers undergoing psychological treatment for smoking cessation. Motivation to quit was assessed pre-treatment and post-treatment with the Readiness to Quit Ladder. Abstinence post-treatment and at 6month follow-up was biochemically verified. Participants with higher levels of pre-treatment and post-treatment motivation were more likely to be abstinent at the end of the treatment (OR=1.36) and at 6month follow-up (OR=4.88). Among abstainers at the end of the treatment (61.9%), higher levels of motivation to quit post-treatment predicted maintaining abstinence at 6months (OR=2.83). Furthermore, participants who failed to quit smoking reported higher levels of motivation to quit post-treatment than they had pretreatment (pMotivation to quit smoking predicted short and long-term cessation, and also predicted long-term maintenance of abstinence. These results have implications for understanding motivational processes of smoking cessation in general, while extending research to Spanish smokers. They may also help in the design of cessation and relapse-prevention interventions. Specifically, the results suggest that motivational enhancement is important throughout the cessation and maintenance periods. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Aims Due to the chronicity of cocaine dependence, practical and effective maintenance interventions are needed to sustain long-term abstinence. We sought to assess the effects of long-term employment-based reinforcement of cocaine abstinence after discontinuation of the intervention. Design Participants who initiated sustained opiate and cocaine abstinence during a 6-month abstinence reinforcement and training program worked as data entry operators and were randomly assigned to a group that could work independent of drug use (Control, n = 24), or an abstinence-contingent employment (n = 27) group that was required to provide cocaine- and opiate-negative urine samples to work and maintain maximum rate of pay. Setting A nonprofit data entry business. Participants Unemployed welfare recipients who persistently used cocaine while in methadone treatment. Measurements Urine samples and self-reports were collected every six months for 30 months. Findings During the employment year, abstinence-contingent employment participants provided significantly more cocaine-negative samples than controls (82.7% and 54.2%; P = .01, OR = 4.61). During the follow-up year, the groups had similar rates of cocaine-negative samples (44.2% and 50.0%; P = .93), and HIV-risk behaviors. Participants’ social, employment, economic, and legal conditions were similar in the two groups across all phases of the study. Conclusions Employment-based reinforcement effectively maintains long-term cocaine abstinence, but many patients relapse to use when the abstinence contingency is discontinued, even after a year of abstinence-contingent employment. Relapse could be prevented in many patients by leaving employment-based abstinence reinforcement in place indefinitely, which could be facilitated by integrating it into typical workplaces.

    2009-09-01

    The current study examined gender differences in personal and psychological characteristics among drug-abstinent Israeli inmates. The study focuses primarily on three personal variables: sense of coherence (SOC), anxiety, and hostility. Additional factors that were examined are demographic variables, which include background, crime, and drug addiction. The sample included 119 inmates (65 males and 54 females) who abstained from drugs use for two different time intervals--up to one year, and more than one year--and did not receive treatment. Overall, males and females shared similar backgrounds except for a higher rate of sexual abuse among female inmates. No gender differences were found in recidivism. These findings show that drug-addicted female inmates injected drugs to a greater extent than males. They also indicated that male inmates remained abstinent for longer periods than female inmates. Additionally, length of abstinence was related to higher SOC, lower trait anxiety, and less hostility among male inmates compared to female inmates. Among female inmates, length of abstinence was related to lower SOC, higher trait anxiety, and no change in hostility. These findings may indicate the need to require separate gender-oriented therapeutic interventions.

    The effect of chronic administration of morphine and its withdrawal on the binding of 3H-(3-MeHis2)thyrotropin releasing hormone (3H-MeTRH) to membranes of the spinal cord of the rat was determined. Male Sprague-Dawley rats were implanted with either 6 placebo or 6 morphine pellets (each containing 75-mg morphine base) during a 7-day period. Two sets of animals were used. In one, the pellets were left intact at the time of sacrificing (tolerant-dependent) and in the other, the pellets were removed 16 hours prior to sacrificing (abstinent rats). In placebo-pellet-implanted rats, 3H-MeTRH bound to the spinal cord membranes at a single high affinity binding site with a Bmax of 21.3 +/- 1.6 fmol/mg protein, and an apparent dissociation constant Kd of 4.7 +/- 0.8 nM. In morphine tolerant-dependent or abstinent rats, the binding constants of 3H-MeTRH to spinal cord membranes were unaffected. Previous studies from this laboratory indicate that TRH can inhibit morphine tolerance-dependence and abstinence processes without modifying brain TRH receptors. Together with the present results, it appears that the inhibitory effect of TRH on morphine tolerance-dependence and abstinence is probably not mediated via central TRH receptors but may be due to its interaction with other neurotransmitter systems.

    Problem gamblers account for almost one-third of the industry's total revenue with the adverse effects of problem gambling including significant financial loss, legal and occupational difficulties, family problems, psychological distress and suicide. As such, it is important to understand the influential factors in gambling abstinence and relapse, which will assist in the development of relapse prevention methods in therapeutic treatment regimes. This paper reported the role of a set of seven predictors in distinguishing between abstinent and relapsed gamblers among 75 Gambling Anonymous (GA) members (55 males; 20 females; Mean age 45 years) in Southeast Queensland. The measures taken were meeting Attendance and Participation, Social Support, God Belief, Belief in a Higher Power, Working the 12-steps of Recovery, Gambling Urges and Erroneous Cognitions. Discriminant analysis revealed that the variables separating the two groups were significant, suggesting that GA members achieving abstinence could be distinguished from those who relapsed, with Attendance and Participation, and Social Support contributing the greatest influence on member's ability to abstain from gambling. The findings suggested that GA member's involvement in meetings, and support from family and friends had significant impact on their gambling abstinence. In contrast, increased gambling urges and erroneous cognitions increased the chance of relapse.

    The authors reviewed the content, methods, and overall quality of 21 curricula used in abstinence-only-until-marriage programs. Only materials designed for use in middle school grades (fifth to eighth) or with middle school-aged audiences (9-13 years of age), which presented the abstinence message in at least 40% of their content, were included. A rating instrument adapted from 2 sets of education guidelines structured the assessment of each curriculum. Four experienced teachers rated each curriculum. Curricula exhibited considerable variability in overall quality ratings. While on average, materials scored a 3.33 on a 1-to-5 scale (1 = Unacceptable; 5 = Excellent), 12 curricula received summative scores above the average, with 4 scoring 4.0 or higher. Eight curricula, however, received a below-average rating. While abstinence materials vary considerably in terms of overall quality, the values and world views underlying this sample of curricula were clear and consistent: those who develop abstinence education curricula value nonsexual antecedents of sexual behavior such as skills (goal setting, decision making, and assertiveness), ideals (fidelity, friendships), and psychological factors such as self-esteem.

    This study aims to investigate sleep quality and the subjective dream experience in alcohol-dependent patients during withdrawal and abstinence compared with healthy controls. Thirty-seven patients with alcohol dependency and 35 healthy control subjects were asked to fill in several questionnaires and to give information about their subjective sleep and dream experiences. Twelve patients participated in a follow-up interview 4 weeks later. Sleep quality is impaired in alcohol-dependent patients during detoxication, and the subjective dream experience is more negatively toned compared with healthy controls. Both sleep quality and dream experience improves slightly after 4 weeks of abstinence. Patients with alcohol dependency during withdrawal and abstinence dream significantly more often about alcohol. However, none of the abstinent alcohol-dependent patients dreamed about alcohol during withdrawal. This study shows that the subjective sleep and dream quality is strongly impaired in patients with alcohol dependency. Differences in the dream experience between alcohol-dependent patients and healthy controls are in accordance with the continuity hypotheses of dreaming. The hypothesis of dreaming about alcohol as a compensatory effect, however, could not be confirmed.

    Smoking prevalence is alarmingly high among the homeless. Few studies have focused on predictors of smoking abstinence in this population. Subjective social status, a person's ranking of their own social standing relative to others in the United States or in their own self-defined communities, has predicted smoking cessation among domiciled smokers in analyses adjusted for objective socioeconomic status and other demographic variables. This study examined if subjective social status predicted quit-day abstinence among homeless smokers making a quit attempt. Longitudinal study using self-reported survey data. Transitional homeless shelter in Dallas, Texas. A total of 57 homeless smokers enrolled in a cessation program. Predictors were the Subjective Social Status-U.S (SSS-U.S.) and the Subjective Social Status-Community (SSS-Community) ladders measured 1 week pre quit. Covariates were sociodemographics and tobacco dependence measured 1 week pre quit. The outcome was self-reported and biochemically verified smoking abstinence on the quit day. Analysis . Covariate-adjusted logistic regression models. Higher rankings on the SSS-U.S. ladder, but not the SSS-Community ladder, predicted abstinence on the quit day (p = .005). Lower rankings on the SSS-U.S. ladder predicted increased risk of relapse on the quit day or the inability to quit at all. The SSS-U.S. ladder might be useful in identifying homeless smokers needing additional preparation and intervention before initiating a quit attempt.

  11. Attitudes toward harm reduction and abstinence-only approaches to alcohol misuse among Alaskan college students

    2013-08-01

    Full Text Available Background. Harm reduction is a public health approach that aims to guide hazardous drinkers to change unsafe drinking and minimize alcohol-related consequences without requiring abstinence. In contrast, abstinence-based interventions are designed for people with more severe alcohol problems and they aim to eliminate consequences via complete abstinence from alcohol. Current best practices for treating college student alcohol misuse involve harm reduction strategies, but no research has been conducted examining students’ perceptions of these strategies. Objective. Understanding attitudes is critical prior to the implementation of an intervention in a new setting, particularly when attitudes may serve as barriers to treatment enrolment and retention. For this reason, we sought to examine attitudes toward contrasting alcohol misuse interventions among college students in two large public universities in the circumpolar north. Design. A web-based survey was conducted with 461 students from two public universities in Alaska. Participants completed questionnaires assessing attitudes toward alcohol treatment, current drinking behaviour, and demographic information. Results. Findings indicated that emerging adult (18–25 years old students who would be targets of future interventions (hazardous drinkers evidenced more positive attitudes toward harm reduction than abstinence-only approaches. Conclusion. This research provides support for the implementation of harm reduction intervention strategies for Alaskan college students who misuse alcohol. It is likely that harm reduction will be acceptable in this population.

    1998-08-01

    Selegiline is an irreversible inhibitor of monoamine oxidase B with trophic and neuroprotective effects. Because of evidence for decreased dopaminergic function during the withdrawal syndromes associated with opiates and other medications with potential for abuse, we investigated effects of treatment with selegiline on in vitro measures of dopamine efflux following opiate withdrawal. Treatment with 2.0 mg/kg/day of selegiline did not modify the severity of opiate withdrawal, as assessed by weight loss over the first 3 days of abstinence. Opiate withdrawal increased immobility in response to a forced warm water swim test performed during the second and third weeks of abstinence following the onset of withdrawal. Brain slices obtained from the nucleus accumbens of opiate-withdrawn animals immediately following swim stress testing displayed diminished efflux of tritiated dopamine after two in vitro exposures to cocaine or amphetamine. Cocaine increases neurotransmitter efflux through blockade of dopamine reuptake, while amphetamine augments efflux by stimulating release of dopamine from intracellular storage vesicles. Although slices from opiate withdrawal subjects showed decreases in efflux after in vitro treatment with these agents, no differences were observed after exposure to 4-aminopyridine, which increases neurotransmitter release by prolonging action potential duration. These findings indicate mechanisms of action that are specific for catecholamine neurotransmitter systems are important for demonstrating long-term changes in dopaminergic function following opiate withdrawal. Selegiline prevented decreases in the efflux of tritiated dopamine in slices obtained from opiate-withdrawn subjects. In addition, selegiline decreased withdrawal-induced immobility during warm water swim testing. In conclusion, treatment with selegiline can prevent long-term changes in stress-induced immobility and deficits in presynaptic dopaminergic function that occur following the

    To compare Five-Factor personality traits in patients maintaining abstinence and relapsed patients (i.e. those who relapsed within a year after treatment), following eight weeks of in-house treatment and three months of out-patient treatment. In longitudinal studies, a sample of 190 patients was analysed (49 females and 141 males; mean age: 43). The patients participated in therapeutic programmes at several addiction treatment centres across Poland. Personality traits were measured using the NEO PI-R inventory proposed by Costa and McCrae (adapted into Polish by Jerzy Siuta) at the initial stage of the treatment. Abstinence was assessed based on the interview. As far as the main traits are concerned, abstinent patients have higher levels of Agreeableness and Conscientiousness than patients who relapsed within a year following the therapy. Moreover, they are characterised by higher levels of constituent traits: Straightforwardness, Ideas and Altruism, as well as higher levels of Order, Self-Discipline and Dutifulness. However, their levels of Hostility are lower compared to patients not maintaining abstinence. After one year follow-up, the group maintaining abstinence is characterised by a higher Agreeableness and Conscientiousness, which is beneficial for cooperation with others as well as undertaking and realising tasks. Moreover, lower constituent values of Neuroticism are linked to higher adaptability and greater therapy participation than in a relapsed group. An early identification of patients bearing traits linked to lower adaptability will decrease the possibility of relapse thanks to making a greater effort at enhancing treatment participation while paying special attention to any co-existing psychopathology.

    The aim of this paper was to investigate the subjective responses of abstinent heroin users to both neutral and negative stimuli and the related hypothalamus-pituitary-adrenal reactions to emotional experience in relationship to their perception of childhood adverse experiences. Thirty male abstinent heroin dependents were included in the study. Emotional responses and childhood neglect perception were measured utilizing the State-Trait Anxiety Inventory Y-1 and the Child Experience of Care and Abuse Questionnaire. Neutral and unpleasant pictures selected from the International Affective Picture System and the Self-Assessment Manikin procedure have been used to determine ratings of pleasure and arousal. These ratings were compared with normative values obtained from healthy volunteers used as control. Blood samples were collected before and after the experimental sessions to determine both adrenocorticotropic hormone and cortisol plasma levels. Basal anxiety scores, cortisol and adrenocorticotropic hormone levels were higher in abstinent heroin users than in controls. Tests showed that anxiety scores did not change in controls after the vision of neutral slides, whilst they did in abstinent heroin addicts, increasing significantly; and increased less significantly after the unpleasant task, in comparison to controls. Abstinent heroin users showed significantly higher levels of parent antipathy and childhood emotional neglect perception than controls for both the father and the mother. Plasma adrenocorticotropic hormone and cortisol levels did not significantly increase after unpleasant slide set viewing among addicted individuals, because of the significantly higher basal levels characterizing the addicted subjects in comparison with controls. Multiple regression correlation showed a significant relationship between childhood neglect perception, arousal reaction, impaired hypothalamus-pituitary-adrenal axis response and addiction severity.

    Methamphetamine abuse is linked with brain abnormalities, but its peripheral effects constitute an integral aspect of long-term methamphetamine use. Eight male rhesus monkeys with long histories of intravenous methamphetamine self-administration were evaluated 1 day, and 1, 4, 12, 26, and 52 weeks after their last methamphetamine self-administration session. On test days, isoflurane-anesthetized animals received a 0.35 mg/kg IV methamphetamine challenge. A control group consisted of 10 age and gender matched drug naïve monkeys. Cardiovascular responses to methamphetamine were followed for 2.5h. Echocardiograms were acquired at 3 and 12 months of abstinence and in the control animals. No pre-methamphetamine baseline differences existed among 7 physiological measures across all conditions and controls. As expected, methamphetamine increased heart rate and blood pressure in controls. However, immediately following the self-administration period, the blood pressure response to methamphetamine challenge was reduced when compared to control monkeys. The peak and 150-min average heart rate increases, as well as peak blood pressure increases following methamphetamine were significantly elevated between weeks 12 to 26 of abstinence. These data indicate the development of tolerance followed by sensitization to methamphetamine cardiovascular effects. Echocardiography demonstrated decreased left ventricular ejection fraction and cardiac output at 3 months of abstinence. Importantly, both cardiovascular sensitization and cardiotoxicity appeared to be reversible as they returned toward control group levels after 1 year of abstinence. Enhanced cardiovascular effects may occur after prolonged abstinence in addicts relapsing to methamphetamine and may underlie clinically reported acute cardiotoxic events.

    The role that sex education plays in the initiation of sexual activity and risk of teen pregnancy and sexually transmitted disease (STD) is controversial in the United States. Despite several systematic reviews, few epidemiologic evaluations of the effectiveness of these programs on a population level have been conducted. Among never-married heterosexual adolescents, aged 15-19 years, who participated in Cycle 6 (2002) of the National Survey of Family Growth and reported on formal sex education received before their first sexual intercourse (n = 1719), we compared the sexual health risks of adolescents who received abstinence-only and comprehensive sex education to those of adolescents who received no formal sex education. Weighted multivariate logistic regression generated population-based estimates. Adolescents who received comprehensive sex education were significantly less likely to report teen pregnancy (OR(adj) = .4, 95% CI = .22- .69, p = .001) than those who received no formal sex education, whereas there was no significant effect of abstinence-only education (OR(adj) = .7, 95% CI = .38-1.45, p = .38). Abstinence-only education did not reduce the likelihood of engaging in vaginal intercourse (OR(adj) = .8, 95% CI = .51-1.31, p = .40), but comprehensive sex education was marginally associated with a lower likelihood of reporting having engaged in vaginal intercourse (OR(adj) = .7, 95% CI = .49-1.02, p = .06). Neither abstinence-only nor comprehensive sex education significantly reduced the likelihood of reported STD diagnoses (OR(adj) = 1.7, 95% CI = .57-34.76, p = .36 and OR(adj) = 1.8, 95% CI = .67-5.00, p = .24 respectively). Teaching about contraception was not associated with increased risk of adolescent sexual activity or STD. Adolescents who received comprehensive sex education had a lower risk of pregnancy than adolescents who received abstinence-only or no sex education.

    This study examined mediators and moderators of short-term treatment effectiveness from the iQUITT Study (Quit Using Internet and Telephone Treatment), a 3-arm randomized trial that compared an interactive smoking cessation Web site with an online social network (enhanced Internet) alone and in conjunction with proactive telephone counseling (enhanced Internet plus phone) to a static Internet comparison condition (basic Internet). The analytic sample was N = 1,236 participants with complete 3-month data on all mediating variables. The primary outcome was 30-day point prevalence abstinence (ppa) at 3 months. Recognizing the importance of temporal precedence in mediation analyses, we also present findings for 6-month outcomes. Purported mediators were treatment utilization and changes in psychosocial constructs. Proposed moderators included baseline demographic, smoking, and psychosocial variables. Mediation analyses examined the extent to which between-arm differences in 30-day ppa could be attributed to differential Web site utilization, telephone counseling, and associated changes in smoking self-efficacy and social support for quitting. Effect modification analyses fitted interactions between treatment and prespecified moderators on abstinence. Significant mediators of 30-day ppa were changes in smoking temptations, quitting confidence, and positive and negative partner support, which were strongly associated with increased Web site utilization. The addition of telephone counseling to an enhanced Web site further improved abstinence rates, partly via an association with increased quitting confidence. Baseline smoking rate was the only significant moderator. Increased treatment utilization and associated changes in several psychosocial measures yielded higher abstinence rates. Findings validate the importance of treatment utilization, smoking self-efficacy, and social support to promote abstinence. © The Author 2014. Published by Oxford University Press on behalf

    Full Text Available Internet Gaming Disorder (IGD is positioned in the appendix of the DSM-5 as a condition requiring further study. The IGD criteria refer to withdrawal symptoms, including irritability, anxiety, or sadness, that follow cessation of Internet gaming (APA, 2013. The aim of this study was to prospectively examine the nature of Internet gaming withdrawal symptoms, if they occur, under gaming abstinence conditions. This study employed a repeated-measures protocol to examine the cognitive-affective reactions of participants undertaking an 84-h Internet gaming abstinence period. The sample included individuals who met the IGD criteria as well as those who regularly played Internet games but did not meet the IGD criteria. Outcome variables included affect (positive and negative, psychological distress (depression, anxiety, stress, and Internet gaming withdrawal symptoms (craving/urge, thoughts about gaming, inability to resist gaming. A total of 24 participants (Mage = 24.6 years, SD = 5.8 were recruited from online gaming communities, and completed a series of online surveys before, during, and after abstaining from Massively Multiplayer Online (MMO games. Both the IGD group and the non-IGD group experienced an abstinence-induced decline in withdrawal symptomatology, negative affect, and psychological distress. The IGD group experienced its largest decline in withdrawal symptomatology within the first 24 h of abstinence. These preliminary data suggest that gaming withdrawal symptoms may follow, at least initially, negative linear and quadratic trends. Further prospective work in larger samples involving longer periods of abstinence is required to verify and expand upon these observations.

    Emerging literature suggests that frequency of use of electronic cigarettes (e-cigarettes) may be an important moderating variable in the relationship between e-cigarette use and smoking cessation. However, few studies have focused specifically on treatment-seekers, a group that may differ in important ways from smokers in the general population. This study looks at the relationship between e-cigarette use frequency and abstinence among a sample of treatment-seeking tobacco users. Seven-month follow-up survey data from N=2760 treatment-seeking tobacco users who utilized statewide tobacco quitlines in three states were used to assess the relationship between 30-day point prevalence abstinence and e-cigarette use frequency at follow-up. E-cigarette use was examined in two ways. First, we looked at any use in the past 30days versus no use. Additionally, past 30-day e-cigarette use frequency was categorized into four groups: 0days, 1-5days - infrequent, 6-29days - intermediate, 30days - daily. Logistic regression models were constructed predicting 30-day point prevalence tobacco abstinence. Both infrequent (AOR=0.35; CI=0.20-0.59) and intermediate (AOR=0.50; CI=0.32-0.80) past 30-day e-cigarette use were associated with lower rates of tobacco abstinence versus no past 30-day use. However, daily e-cigarette users (AOR=1.16; CI=0.71-1.70) had similar 30-day abstinence when compared to non-users. Results from this study of treatment-seekers support findings from studies of general population tobacco users that suggest frequency of e-cigarette use is an important moderating variable in the relationship between e-cigarette use and tobacco cessation. Future studies should employ more refined measures of e-cigarette use. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available In this paper, we present a new questionnaire for the assessment of self-control as an individual trait. We describe the process of construction of this assessment tool. We also report the results of relevant validation studies. The questionnaire has two independent versions, one based on self-reports (NAS-50 and another one based on other-reports (NAS-40. The first version consists of five subscales (10 items each, called Initiative and Persistence (IP, Proactive Control (PC, Switching and Flexibility (SF, Inhibition and Adjournment (IA, and Goal Maintenance (GM. Seven samples of participants (N = 934 altogether took part in the validation study. The second version has not been split into subscales. Both versions obtained satisfactory indices of internal consistency, assessed with Cronbach’s alpha (for NAS- 50 total score a = .861, for the subscales a between .726 and .867; for NAS-40 a = .844. The NAS-50 and NAS-40 scores were highly correlated with other measures of self-control, including Tangney, Baumeister, and Boone’s (2004 self-control scale. They also proved to be entirely independent of general intelligence. In conclusion, both versions can be regarded reliable and valid enough, and therefore suitable for the assessment of trait self-control for research purposes.

  5. Impaired response inhibition in the rat 5 choice continuous performance task during protracted abstinence from chronic alcohol consumption.

    Directory of Open Access Journals (Sweden)

    Cristina Irimia

    Full Text Available Impaired cognitive processing is a hallmark of addiction. In particular, deficits in inhibitory control can propel continued drug use despite adverse consequences. Clinical evidence shows that detoxified alcoholics exhibit poor inhibitory control in the Continuous Performance Task (CPT and related tests of motor impulsivity. Animal models may provide important insight into the neural mechanisms underlying this consequence of chronic alcohol exposure though pre-clinical investigations of behavioral inhibition during alcohol abstinence are sparse. The present study employed the rat 5 Choice-Continuous Performance Task (5C-CPT, a novel pre-clinical variant of the CPT, to evaluate attentional capacity and impulse control over the course of protracted abstinence from chronic intermittent alcohol consumption. In tests conducted with familiar 5C-CPT conditions EtOH-exposed rats exhibited impaired attentional capacity during the first hours of abstinence and impaired behavioral restraint (increased false alarms during the first 5d of abstinence that dissipated thereafter. Subsequent tests employing visual distractors that increase the cognitive load of the task revealed significant increases in impulsive action (premature responses at 3 and 5 weeks of abstinence, and the emergence of impaired behavioral restraint (increased false alarms at 7 weeks of abstinence. Collectively, these findings demonstrate the emergence of increased impulsive action in alcohol-dependent rats during protracted alcohol abstinence and suggest the 5C-CPT with visual distractors may provide a viable behavioral platform for characterizing the neurobiological substrates underlying impaired behavioral inhibition resulting from chronic intermittent alcohol exposure.

    Rates of cannabis use among patients with schizophrenia are high, however little is understood about clinical effects of continued cannabis use and cessation after illness onset. Therefore, we investigated the effects of 28-days of cannabis abstinence on psychotic and depressive symptomatology in cannabis dependent patients with schizophrenia. Males with cannabis dependence and co-morbid schizophrenia (n=19) and non-psychiatric controls (n=20) underwent 28-days of monitored cannabis abstinence. Clinical symptoms were assessed at baseline and then weekly. Abstinence was encouraged using weekly therapy sessions and contingency reinforcement, confirmed by twice-weekly urine assays. Forty-two percent (8/19) of patients and 55% (11/20) of controls achieved 28-days of sustained cannabis abstinence. In patients, PANSS subscores did not change over time irrespective of abstinence status. In contrast, patient abstainers demonstrated a more pronounced reduction in depression scores compared to non-abstainers, however, the Abstinence Status x Time interaction was non-significant. Short-term (28-days) cannabis abstinence is not associated with improvement in psychotic symptoms, but may be associated with improvement in depressive symptomatology in patients with schizophrenia. Future studies employing larger samples as well as a continuous cannabis-using group may help to better characterize the causal effects of cannabis on symptom outcomes in this disorder.

  10. Probing the Behavioral and Neurophysiological Effects of Acute Smoking Abstinence on Drug and Nondrug Reinforcement During a Cognitive Task.

    2017-06-01

    Smoking abstinence is theorized to increase smoking reinforcement and decrease nondrug reinforcement. A separate literature demonstrates the detrimental effects of abstinence on cognition. The present study integrates these two areas by examining the separate and combined effects of reinforcement and smoking abstinence on behavior and a neurophysiological index of response monitoring (ie, error-related negativity [ERN]) during a cognitive task. After a screening visit, adult smokers attended two laboratory visits, once while smoking and once while abstinent. Participants completed a flanker task under cigarette-, money-, and no-reinforcement conditions. The initial 15 participants had an easier reaction time (RT) requirement; to ensure sufficient error rates for ERN computation, a harder RT deadline was employed for the remaining 21 participants. Smoking abstinence reduced speeded accuracy and ERN amplitude only among participants tested with the harder RT deadline. Cigarette and money reinforcement each increased speeded accuracy and ERN amplitude compared to no reinforcement. The effect of cigarette reinforcement tended to be greater during abstinence for speeded accuracy but not the ERN. The effect of money reinforcement was unaffected by abstinence. The impact of smoking abstinence on reinforcement may depend on task demands. However, the effects of cigarette and money reinforcement generalize well from operant paradigms to cognitive tasks, fostering integration between the two literatures. Results provided modest evidence of abstinence-induced increases in smoking reinforcement; the absence of abstinence-induced reductions in nondrug reinforcement is consistent with recent work in suggesting that such effects are limited to a subset of sensory reinforcers. This study draws attention to the need for greater integration of reinforcement and cognition to better understand the mechanisms that contribute to smoking relapse. Results emphasize thoughtful

    Context: Due to the chronic nature of cocaine dependence, long-term maintenance treatments may be required to sustain abstinence. Abstinence reinforcement is among the most effective means of initiating cocaine abstinence. Practical and effective means of maintaining abstinence reinforcement programs over time are needed. Objective: Determine whether employment-based abstinence reinforcement can be an effective long-term maintenance intervention for cocaine dependence. Design: Participants (N=128) were enrolled in a 6-month job skills training and abstinence initiation program. Participants who initiated abstinence, attended regularly, and developed needed job skills during the first six months were hired as operators in a data entry business and randomly assigned to an employment only (Control, n = 24) or abstinence-contingent employment (n = 27) group. Setting: A nonprofit data entry business. Participants: Unemployed welfare recipients who persistently used cocaine while enrolled in methadone treatment in Baltimore. Intervention: Abstinence-contingent employment participants received one year of employment-based contingency management, in which access to employment was contingent on provision drug-free urine samples under routine and then random drug testing. If a participant provided drug-positive urine or failed to provide a mandatory sample, then that participant received a temporary reduction in pay and could not work until urinalysis confirmed recent abstinence. Main Outcome Measure: Cocaine-negative urine samples at monthly assessments across one year of employment. Results: During the one-year of employment, abstinence-contingent employment participants provided significantly more cocaine-negative urine samples than employment only participants (79.3% and 50.7%, respectively; p = 0.004, OR = 3.73, 95% CI = 1.60 – 8.69). Conclusions: Employment-based abstinence reinforcement that includes random drug testing is effective as a long-term maintenance

  12. The Knowledge Gap Versus the Belief Gap and Abstinence-Only Sex Education.

    The knowledge gap hypothesis predicts widening disparities in knowledge of heavily publicized public affairs issues among socioeconomic status groups. The belief gap hypothesis extends the knowledge gap hypothesis to account for knowledge and beliefs about politically contested issues based on empirically verifiable information. This analysis of 3 national surveys shows belief gaps developed between liberals and conservatives regarding abstinence-only sex education; socioeconomic status-based knowledge gaps did not widen. The findings partially support both belief gap and knowledge gap hypotheses. In addition, the unique contributions of exposure to Fox News, CNN, and MSNBC in this process were investigated. Only exposure to Fox News was linked to beliefs about abstinence-only sex education directly and indirectly through the cultivation of conservative ideology.

    In 2011, the USA had the second highest teen birth rate of any developed nation, according to the World Bank, . In an effort to lower teen pregnancy rates, several states have enacted policies requiring abstinence-based sex education. In this study, we utilize a difference-in-differences research design to analyze the causal effects of state-level sex education policies from 2000-2011 on various teen sexual health outcomes. We find that state-level abstinence education mandates have no effect on teen birth rates or abortion rates, although we find that state-level policies may affect teen sexually transmitted disease rates in some states.

  15. Lower hypoxic ventilatory response in smokers compared to non-smokers during abstinence from cigarettes.

    Carotid body O 2 -chemosensitivity determines the hypoxic ventilatory response (HVR) as part of crucial regulatory reflex within oxygen homeostasis. Nicotine has been suggested to attenuate HVR in neonates of smoking mothers. However, whether smoking affects HVR in adulthood has remained unclear and probably blurred by acute ventilatory stimulation through cigarette smoke. We hypothesized that HVR is substantially reduced in smokers when studied after an overnight abstinence from cigarettes i.e. after nicotine elimination. We therefore determined the isocapnic HVR of 23 healthy male smokers (age 33.9 ± 2.0 years, BMI 24.2 ± 0.5 kg m -2 , mean ± SEM) with a smoking history of >8 years after 12 h of abstinence and compared it to that of 23 healthy male non-smokers matched for age and BMI. Smokers and non-smokers were comparable with regard to factors known to affect isocapnic HVR such as plasma levels of glucose and thiols as well as intracellular levels of glutathione in blood mononuclear cells. As a new finding, abstinent smokers had a significantly lower isocapnic HVR (0.024 ± 0.002 vs. 0.037 ± 0.003 l min -1 % -1 BMI -1 , P = 0.002) compared to non-smokers. However, upon re-exposure to cigarettes the smokers' HVR increased immediately to the non-smokers' level. This is the first report of a substantial HVR reduction in abstinent adult smokers which appears to be masked by daily smoking routine and may therefore have been previously overlooked. A low HVR may be suggested as a novel link between smoking and aggravated hypoxemia during sleep especially in relevant clinical conditions such as COPD.

    Chronic, frequent cannabis smokers may experience residual and offset effects, withdrawal, and craving when abstaining from the drug. We characterized the prevalence, duration, and intensity of these effects in chronic frequent cannabis smokers during abstinence on a closed research unit. Non-treatment-seeking participants (N = 29 on admission, 66% and 34% remaining after 2 and 4 weeks) provided subjective effects data. A battery of five instruments was computer-administered daily to measure psychological, sensory, and physical symptoms associated with cannabinoid intoxication and withdrawal. Plasma and oral fluid specimens were concurrently collected and analyzed for cannabinoids. Outcome variables were evaluated as change from admission (Day 0) with regression models. Most abstinence effects, including irritability and anxiety were greatest on Days 0-3 and decreased thereafter. Cannabis craving significantly decreased over time, whereas decreased appetite began to normalize on Day 4. Strange dreams and difficulty getting to sleep increased over time, suggesting intrinsic sleep problems in chronic cannabis smokers. Symptoms likely induced by residual drug effects were at maximum intensity on admission and positively correlated with plasma and oral fluid cannabinoid concentrations on admission but not afterward; these symptoms showed overall prevalence higher than cannabis withdrawal symptoms. The combined influence of residual/offset drug effects, withdrawal, and craving was observed in chronic cannabis smokers during monitored abstinence. Abstinence symptoms were generally more intense in the initial phase, implying importance of early intervention in cannabis quit attempts. Sleep disturbance persisting for an extended period suggests that hypnotic medications could be beneficial in treating cannabis dependence. © American Academy of Addiction Psychiatry.

    DRD4 Exon III Variable Number of Tandem Repeat (VNTR) variation was found to interact with bupropion to influence prospective smoking abstinence, in a recently published longitudinal analyses of N = 331 individuals from a randomized double-blind placebo-controlled trial of bupropion and intensive cognitive-behavioral mood management therapy. We used univariate, multivariate, and longitudinal logistic regression to evaluate gene, treatment, time, and interaction effects on point prevalence and continuous abstinence at end of treatment, 6 months, and 12 months, respectively, in N = 416 European ancestry participants in a double-blind pharmacogenetic efficacy trial randomizing participants to active or placebo bupropion. Participants received 10 weeks of pharmacotherapy and 7 sessions of behavioral therapy, with a target quit date 2 weeks after initiating both therapies. VNTR genotypes were coded with the long allele dominant resulting in 4 analysis categories. Covariates included demographics, dependence measures, depressive symptoms, and genetic ancestry. We also performed genotype-stratified secondary analyses. We observed significant effects of time in longitudinal analyses of both abstinence outcomes, of treatment in individuals with VNTR long allele genotypes for both abstinence outcomes, and of covariates in some analyses. We observed non-significantly larger differences in active versus placebo effect sizes in individuals with VNTR long allele genotypes than in individuals without the VNTR long allele, in the directions previously reported. VNTR by treatment interaction differences between these and previous analyses may be attributable to insufficient size of the replication sample. Analyses of multiple randomized clinical trials will enable identification and validation of factors mediating treatment response.

    Rationale Exercise appears to be a promising non-pharmacological treatment for nicotine addiction that may be useful for the vulnerable adolescent population. Objectives To determine if wheel running, an animal model of aerobic exercise, during an abstinence period would decrease subsequent nicotine-seeking in rats that had extended access to nicotine self-administration during adolescence. Methods Male adolescent rats (n = 55) were trained to self-administer saline or nicotine infusions (5 or 10 μg/kg) under a fixed ratio 1 schedule with a maximum of 20 infusions/day beginning on postnatal day 30. After 5 days, access was extended to 23-hr/day with unlimited infusions for a total of 10 days. After the last self-administration session, rats were moved to polycarbonate cages for a 10-day abstinence period where they either had access to a locked or unlocked running wheel for 2-hr/day. Nicotine-seeking was examined following the 10th day of abstinence under a within-session extinction/cue-induced reinstatement paradigm. Results Intake was higher at the 10 μg/kg dose as compared to the 5 μg/kg dose; however, intake did not differ within doses prior to wheel assignment. Compared to saline controls, rats that self-administered nicotine at either dose showed a significant increase in drug-seeking during extinction, and consistent with our hypothesis, exercise during abstinence attenuated this effect. Nicotine led to modest, but significant levels of cue-induced reinstatement; however, in this adolescent-onset model, levels were variable and not affected by exercise. Conclusions Exercise may effectively reduce relapse vulnerability for adolescent-onset nicotine addiction. PMID:23371488

    The Nicotine Metabolite Ratio (NMR, ratio of trans-3’-hydroxycotinine and cotinine), has previously been associated with CYP2A6 activity, response to smoking cessation treatments, and cigarette consumption. We searched for drug metabolizing enzyme and transporter (DMET) gene variation associated with the NMR and prospective abstinence in 2,946 participants of laboratory studies of nicotine metabolism and of clinical trials of smoking cessation therapies. Stage I was a meta-analysis of the association of 507 common single nucleotide polymorphisms (SNPs) at 173 DMET genes with the NMR in 449 participants of two laboratory studies. Nominally significant associations were identified in ten genes after adjustment for intragenic SNPs; CYP2A6 and two CYP2A6 SNPs attained experiment-wide significance adjusted for correlated SNPs (CYP2A6 PACT=4.1E-7, rs4803381 PACT=4.5E-5, rs1137115, PACT=1.2E-3). Stage II was mega-regression analyses of 10 DMET SNPs with pretreatment NMR and prospective abstinence in up to 2,497 participants from eight trials. rs4803381 and rs1137115 SNPs were associated with pretreatment NMR at genome-wide significance. In post-hoc analyses of CYP2A6 SNPs, we observed nominally significant association with: abstinence in one pharmacotherapy arm; cigarette consumption among all trial participants; and lung cancer in four case:control studies. CYP2A6 minor alleles were associated with reduced NMR, CPD, and lung cancer risk. We confirmed the major role that CYP2A6 plays in nicotine metabolism, and made novel findings with respect to genome-wide significance and associations with CPD, abstinence and lung cancer risk. Additional multivariate analyses with patient variables and genetic modeling will improve prediction of nicotine metabolism, disease risk and smoking cessation treatment prognosis. PMID:26132489

    Full Text Available Transcranial direct current stimulation (tDCS can enhance cognitive control functions including attention and top-down regulation over negative affect and substance craving in both healthy and clinical populations, including early abstinent (~1.5 h smokers. The aim of this study was to assess whether tDCS modulates negative affect, cigarette craving, and attention of overnight abstinent tobacco dependent smokers. In this study, 24 smokers received a real and a sham session of tDCS after overnight abstinence from smoking on two different days. We applied anode to the left dorsal lateral prefrontal cortex (DLPFC and cathode to the right supra orbital area for 20min with a current of 2.0mA. We used self-report questionnaires Profile of Mood State (POMS to assess negative affect and Urge to Smoke (UTS Scale to assess craving for cigarette smoking, and a computerized visual target identification task to assess attention immediately before and after each tDCS. Smokers reported significantly greater reductions in POMS scores of total mood disturbance and scores of tension-anxiety, depression-dejection, and confusion-bewilderment subscales after real relative to sham tDCS. Furthermore, this reduction in negative affect positively correlated with the level of nicotine dependence as assessed by Fagerström scale. However, reductions in cigarette craving after real vs. sham tDCS did not differ, nor were there differences in reaction time or hit rate change on the visual task. Smokers did not report significant side effects of tDCS. This study demonstrates the safety of tDCS and its promising effect in ameliorating negative affect in overnight abstinent smokers. Its efficacy in treating tobacco dependence deserves further investigation.

    Negative affect and low distress tolerance have been associated with increased likelihood of alcohol consumption and relapse. This study utilized the Paced Auditory Serial Attention Test - Computerized Version (PASAT-C) to examine affective reactivity, cognitive performance, and distress tolerance during early abstinence among heavy drinking adolescents. Participants, ages 16 to 18 (50% female), were 23 heavy episodic drinking youth (HED) and 23 demographically matched, nondrinking teens (CON). Both groups were drawn from the same schools and assessed at 3 time points: HED was first studied within 10 days (M = 4.26, SD = 4.4) of heavy episodic drinking and then at two 2-week intervals over 4 subsequent weeks of abstinence from alcohol and drugs. CON were studied at the same 2-week intervals. From the findings, it was observed that HED responded with greater emotional response to the PASAT-C (i.e., greater increases in frustration and irritability and greater decreases in happiness) at the initial assessment, but their affective responses diminished with sustained abstinence. CON and HED task performance did not differ at the initial assessment or across time. HED showed faster task discontinuation times to the PASAT-C at the first assessment, and both groups reduced task persistence across testings. Among HED, greater lifetime and recent alcohol consumption, alcohol-induced blackouts, and withdrawal symptoms were associated with increases in negative affect with PASAT-C exposure. Earlier age of onset of alcohol use was linked to poorer performance. Heavy episodic drinking adolescents demonstrated heightened emotional reactivity and poorer distress tolerance to a cognitively challenging task during early abstinence. The combination of elevated negative affect and low distress tolerance may place adolescents at a heightened risk of escalations in or return to alcohol involvement.

  6. Relationships Between Craving Beliefs and Abstinence Self-Efficacy are Mediated by Smoking Motives and Moderated by Nicotine Dependence.

    Decreased abstinence self-efficacy is linked to increased craving and negative affect, as well as poorer smoking outcomes, such as lapse, relapse, and withdrawal symptom severity. Research suggests that beliefs and cognitions concerning ourselves and the world orient us toward specific goals and thus impact our judgments and behavior. This study serves to investigate whether motives for smoking mediate the relationship between beliefs about craving and abstinence self-efficacy judgments and whether this may differ by nicotine dependence. In a sample of 198 smokers (M age = 34.96, 51.8% female, 81.8% Caucasian), self-report measures of craving beliefs, situational abstinence self-efficacy, and smoking motives were measured. We examined the effect of beliefs on abstinence self-efficacy in both craving and negative affect situations, with craving and negative reinforcement smoking motives as mediators, and nicotine dependence as a moderator. Results indicate that craving beliefs predict lower abstinence self-efficacy judgments in craving situations indirectly through increased craving motives. However, this relationship was only significant for less dependent smokers. Additionally, regardless of nicotine dependence, craving beliefs predicted lower abstinence self-efficacy in negative affect situations via increased negative reinforcement smoking motives. These findings suggest that beliefs concerning the specific nature of craving correlate with smoking motives (ie, smoking goals) and thus abstinence self-efficacy judgments. Furthermore, these associations are stronger for less dependent smokers. Such findings suggest the importance of addressing craving beliefs during smoking cessation treatment, especially for less dependent smokers whose craving beliefs are associated with abstinence self-efficacy across multiple situations. © The Author 2015.

    The success of any type of sexual education programme depends on the knowledge and preparedness for practice by adolescents. A recent study has found that an ‘abstinence-only’ sexual education programme is effective in reducing sexual activity among adolescents. Knowledge of abstinence-only sexual education and preparedness for practice as an effective tool for promotion of sexual health among Nigerian secondary school adolescents was studied. An analytic descriptive survey design was used for the study. The research population comprised of all public secondary schools in three southern geopolitical zones of the Niger Delta Region of Nigeria. A multistage sampling technique was used to select 2020 senior secondary school (SS1-SS3) students as sample for the study. A partially self-designed and partially adapted questionnaire from an 'abstinence-only versus comprehensive sex education' debate, from debatepedia (http://wiki.idebate.org/), entitled 'Questionnaire on Nigerian Secondary School Adolescents’ Perspective on Abstinence-Only Sexual Education (QNSSAPAOSE)' was used in eliciting information from respondents. Hypotheses were formulated and tested. Frequency counts, percentage and Pearson Product Moment Correlation were used in analysing data. A greater proportion of secondary school adolescents in this study lacked knowledge of sexual education. About 80% of the respondents could not define sexual education. The general perspective on abstinence-only sexual education was negative, as revealed by the larger number of respondents who demonstrated unwillingness to practice abstinence-only sexual education. Specifically, of those who responded in favour of abstinence-only sexual education, the youngest group of adolescents (11-13 years) and the male respondents were more likely to accept this type of education than the other groups. Poor knowledge of sexual education could be responsible for unwillingness to practice abstinence-only sexual education. Sexual

    Little is known about the information shared during family discussions about sexuality. From a public health perspective, abstinence is one of the most important sexuality topics parents can talk about with adolescents. We sought to characterize the messages mothers communicate to young adolescents regarding abstinence. Content analysis of dyadic discussions that occurred between June 2011-December 2012 between mothers and their 10- to 14-year-old adolescent sons and daughters. Discussions were audio-recorded, transcribed, and a grounded theory approach to content analysis performed. Urban city in Western Pennsylvania. Twenty-one dyads; 15 mother-daughter dyads and 6 mother-son dyads. None. None. Four key themes emerged reflecting the high priority mothers placed on abstinence, delaying their adolescent's sexual debut, and nurturing sexual decision-making skills. Theme 1 focused on ensuring that adolescents understand what abstinence means. In defining abstinence, only 1 mother explained what sex is. The 3 remaining themes emphasized sexual decision-making and emphasized when it is acceptable to stop being abstinent (theme 2), why abstinence is important (theme 3), and mothers' desire to engage in ongoing discussions, particularly when an adolescent was considering becoming sexually active (theme 4). Messages did not vary according to mothers' age or according to adolescent age, gender, or race. Mothers convey complex information about abstinence and sexual decision-making to young, non-sexually active adolescents. Message tailoring on the basis of the adolescents' age or sex was not observed. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc.

    The Intolerance for Smoking Abstinence Discomfort Questionnaire (IDQ-S) assesses distress tolerance specific to nicotine withdrawal. Though developed to assess withdrawal-related distress, the IDQ-S has not been validated among nicotine-deprived, treatment-seeking smokers. The present study extended previous research by examining the predictive utility of the IDQ-S among abstinent, motivated-to-quit smokers. Abstinent, treatment-seeking smokers completed the IDQ-S Withdrawal Intolerance and Lack of Cognitive Coping scales, assessments of nicotine dependence and reinforcement, and smoking history at baseline. At baseline and at 24-h, 2-week, and 1-month follow-up, participants completed a smoking cue-reactivity task (collection of cue-elicited craving and negative affect), and assessments of cigarettes per day (CPD; daily diaries at follow-up), carbon monoxide (CO), and cotinine. Greater IDQ-S Withdrawal Intolerance was associated with younger age, higher nicotine dependence and reinforcement, and less smoking years (ps  .10). Withdrawal intolerance and lack of cognitive coping did not predict smoking outcomes among nicotine-deprived, treatment-seeking smokers, but were associated with smoking characteristics, including nicotine dependence and reinforcement. Withdrawal intolerance and lack of cognitive coping may not be especially useful in predicting craving and smoking behavior, but future studies should replicate the present study's findings and assess the stability of the IDQ-S before forming firm conclusions about its predictive utility.

We recently reported attenuated mismatch negativity (MMN and altered P50 sensory gating in chronic cannabis users. This study investigated the extent of brain functional recovery (indexed by MMN and P50 in chronic users after cessation of use. Eighteen ex-users (median 13.5 years prior regular use; median 3.5 years abstinence and 18 nonusers completed (1 a multifeature oddball task with duration, frequency, and intensity deviants and (2 a P50 paired-click paradigm. Trend level smaller duration MMN amplitude and larger P50 ratios (indicative of poorer sensory gating were observed in ex-users compared to controls. Poorer P50 gating correlated with prior duration of cannabis use. Duration of abstinence was positively correlated with duration MMN amplitude, even after controlling for age and duration of cannabis use. Impaired sensory gating and attenuated MMN amplitude tended to persist in ex-users after prolonged cessation of use, suggesting a lack of full recovery. An association with prolonged duration of prior cannabis use may indicate persistent cannabis-related alterations to P50 sensory gating. Greater reductions in MMN amplitude with increasing abstinence (positive correlation may be related to either self-medication or an accelerated aging process.

    The prevalence of cigarette smoking among persons living with HIV/AIDS (PLWHA) is approximately 40%, significantly higher than that of the general population. Identifying predictors of successful smoking cessation for PLWHA is necessary to alleviate the morbidity and mortality associated with smoking in this population. Weight gain has been associated with smoking relapse in the general population, but has not been studied among PLWHA. Data from 474 PLWHA enrolled in a smoking cessation randomized clinical trial were analyzed to examine the effect of BMI change, from baseline to 3-month follow-up, on smoking outcomes using multiple logistic regression. The odds of 7-day smoking abstinence at 3-month follow-up were 4.22 (95% CI=1.65, 10.82) times higher for participants classified as BMI decrease and 4.22 (95% CI=1.62, 11.01) times higher for participants classified as BMI increase as compared to participants with a minimal increase or decrease in BMI. In this sample, both weight gain and loss following smoking cessation were significantly associated with abstinence at 3-month follow-up among HIV-infected smokers. Further research and a better understanding of predictors of abstinence will encourage more tailored interventions, with the potential to reduce morbidity and mortality. PMID:26666313

    Full Text Available Pathological gambling (PG is a chronic mental disorder characterized by a difficulty restraining gambling behavior despite negative consequences. Although brain abnormalities in patients with substance use disorders are caused by repetitive drug use and recover partly with drug abstinence, the relationship between brain activity and duration of illness or abstinence of gambling behavior in PG patients remains unclear. Here, using functional magnetic resonance imaging, we compared the brain activity of 23 PG patients recruited from a treatment facility with 27 demographically-matched healthy control subjects during reward anticipation, and examined the correlations between brain activity and duration of illness or abstinence in PG patients. During reward anticipation, PG patients showed decreased activity compared to healthy controls in a broad range of the reward system regions, including the insula cortex. In PG patients, activation in the left insula showed a significant negative correlation with illness duration. Our findings suggest that insular activation during reward anticipation may serve as a marker of progression of pathological gambling.

    Full Text Available E-cigarettes are the most popular method of quitting smoking in England and most are purchased in specialist vape shops. This qualitative study explores how the vape shop environment is experienced by quitters to support smoking abstinence. Semi-structured qualitative interviews were conducted to elicit experiences of e-cigarette use, including experiences of vape shops, in 40 people who had used e-cigarettes in a quit attempt. Observations of six shops in a range of locations were also undertaken. Interview and observation data were analysed using inductive thematic analysis and triangulated. At an individual level, smoking abstinence was supported through shop assistants’ attempts to understand customers’ smoking preferences in order to: (i tailor advice about the most appropriate product; and (ii offer an ongoing point of contact for practical help. At an interpersonal level, shops offered opportunity to socialise and reinforce a vaping identity, although the environment was perceived as intimidating for some (e.g., new and female users. At a structural level, shops ensured easy access to products perceived to be good value by customers and had adapted to legislative changes. Vape shops can provide effective behavioural support to quitters to maintain smoking abstinence. Health professionals could capitalise on this through partnership working with shops, to ensure best outcomes for clients wanting to use e-cigarettes to quit smoking.

    The purpose of this study was to identify predictors of sexual behavior and condom use in African American adolescents, as well as to evaluate the effectiveness of comprehensive sexuality and abstinence-only education to reduce adolescent sexual behavior and increase condom use. Participants included 450 adolescents aged 12-14 years in the southern United States. Regression analyses showed favorable attitudes toward sexual behavior and social norms significantly predicted recent sexual behavior, and favorable attitudes toward condoms significantly predicted condom usage. Self-efficacy was not found to be predictive of adolescents' sexual behavior or condom use. There were no significant differences in recent sexual behavior based on type of sexuality education. Adolescents who received abstinence-only education had reduced favorable attitudes toward condom use, and were more likely to have unprotected sex than the comparison group. Findings suggest that adolescents who receive abstinence-only education are at greater risk of engaging in unprotected sex.

    Research into the effectiveness of interventions for problematic gaming has been limited by a lack of data concerning the clinical characteristics of voluntary treatment-seekers; the nature and history of their gaming problems; and, their reasons for seeking help. The study aimed to identify variables predictive of short-term commitment to gaming abstinence following initial voluntary contact with an online help service. A total of 186 adult gamers with gaming-related problems were recruited online. Participants completed the DSM-5 Internet gaming disorder (IGD) checklist, Depression Anxiety Stress Scales-21, Internet Gaming Cognition Scale, Gaming Craving Scale, and Gaming Quality of Life Scale. A one-week follow up survey assessed adherence with intended gaming abstinence. Abstainers were less likely to have withdrawal symptoms and less likely to play action shooting games. Participants with mood symptoms (40% of the total) reported significantly more IGD symptoms, stronger maladaptive gaming cognitions (e.g., overvaluing game rewards), more previous occurrences of gaming problems, and poorer quality of life. However, mood symptoms did not predict abstinence from or continuation of gaming. Adults with gaming disorder seeking help to reduce their gaming may benefit initially from strategies that manage withdrawal and psychoeducation about riskier gaming activities.

    Light smoking is particularly prevalent among Latino smokers. Nicotine replacement (NRT) and varenicline are effective medications for smoking cessation for moderate-heavy smokers but have not been tested in light smokers, and thus, there are no treatment guidelines for use with light smokers. This pilot trial tested the efficacy of NRT and varenicline in increasing smoking abstinence among Latino light smokers. A 3-group (NRT, varenicline, and varenicline-placebo) randomized design was used, and Latino light smokers (≤10 cigarettes per day) received 12 weeks of treatment, which included a culturally informed behavioral health session and ongoing medication management visits. At follow-up, there were no abstinent participants in the placebo and NRT groups. However, 30% of participants in the varenicline group were abstinent at the 3-, 4-, and 6-month follow-up. This study represents the only investigation that specifically targets Latino light smokers using these treatments and characterizing their treatment adherence. Copyright © 2012 Elsevier Inc.

    2016-04-01

    Drinking, abstinence, and academic motives have been previously linked with alcohol consumption in high school and college students; however, little research has examined the impact of such sources of motivations concurrently. Drawing from self-determination theory (SDT; Ryan & Deci, 2000), the current study tested the hypothesis that alcohol-related and academic motives would be associated with one another along internal vs. external focused dimensions. We also examined the relative influence of these motives on alcohol consumption. College students (N=226) completed self-report measures assessing drinking motives, abstinence motives, academic motives, and alcohol-related outcomes. Findings suggest that drinking motives are related to abstinence motives but not academic motives. Both forms of alcohol-related motives were related to alcohol use and consequences; no associations between academic motives and alcohol variables were observed. The lack of associations among academic motives, alcohol-related motives, and alcohol variables departs from previous findings suggesting that academic motives impact alcohol use. The current findings indicate a greater understanding of the interplay of motivational sets related to salient issues for youth, such as academics, is needed in order to expand intervention models for alcohol use in such populations.

    Two methods of nicotine fading as a smoking cessation preparation technique were compared. A brand-switching procedure and a three-stage set of "Nicotine Faders" graduated filters were the preparation strategies. Both methods implemented a putative 30-50-80% nicotine exposure reduction schedule in three weekly phases. There were a total of 110 study participants (57 in brand switching) enrolled in eight clinic groups. Results indicated that at the 80% reduction level, meaningful reductions in nicotine (measured by its metabolite cotinine) and carbon monoxide (CO) exposure were measurable with both nicotine fading procedures. Overall pooled nicotine and CO exposure drops from baselines of 48.2% and 35.5%, respectively, were recorded. The abstinence outcome measures (pooled 1-year abstinence prevalence = 30.9%) were not significantly different between the two preparation strategies. Trends in nicotine and CO exposure drops, and abstinence outcome measures, however, were consistently in favor of the graduated filters. Potential advantages of filters in the context of a preparation-for-quitting strategy were suggested.

  20. Distinct Mu, Delta, and Kappa Opioid Receptor Mechanisms Underlie Low Sociability and Depressive-Like Behaviors During Heroin Abstinence

    Addiction is a chronic disorder involving recurring intoxication, withdrawal, and craving episodes. Escaping this vicious cycle requires maintenance of abstinence for extended periods of time and is a true challenge for addicted individuals. The emergence of depressive symptoms, including social withdrawal, is considered a main cause for relapse, but underlying mechanisms are poorly understood. Here we establish a mouse model of protracted abstinence to heroin, a major abused opiate, where both emotional and working memory deficits unfold. We show that delta and kappa opioid receptor (DOR and KOR, respectively) knockout mice develop either stronger or reduced emotional disruption during heroin abstinence, establishing DOR and KOR activities as protective and vulnerability factors, respectively, that regulate the severity of abstinence. Further, we found that chronic treatment with the antidepressant drug fluoxetine prevents emergence of low sociability, with no impact on the working memory deficit, implicating serotonergic mechanisms predominantly in emotional aspects of abstinence symptoms. Finally, targeting the main serotonergic brain structure, we show that gene knockout of mu opioid receptors (MORs) in the dorsal raphe nucleus (DRN) before heroin exposure abolishes the development of social withdrawal. This is the first result demonstrating that intermittent chronic MOR activation at the level of DRN represents an essential mechanism contributing to low sociability during protracted heroin abstinence. Altogether, our findings reveal crucial and distinct roles for all three opioid receptors in the development of emotional alterations that follow a history of heroin exposure and open the way towards understanding opioid system-mediated serotonin homeostasis in heroin abuse.

    Full Text Available Abstract Background Many studies of cocaine-responsive gene expression have focused on changes occurring during cocaine exposure, but few studies have examined the persistence of these changes with cocaine abstinence. Persistent changes in gene expression, as well as alterations induced during abstinence may underlie long-lasting drug craving and relapse liability. Results Whole-genome expression analysis was conducted on a rat cocaine binge-abstinence model that has previously been demonstrated to engender increased drug seeking and taking with abstinence. Gene expression changes in two mesolimbic terminal fields (mPFC and NAc were identified in a comparison of cocaine-naïve rats with rats after 10 days of cocaine self-administration followed by 1, 10, or 100 days of enforced abstinence (n = 6-11 per group. A total of 1,461 genes in the mPFC and 414 genes in the NAc were altered between at least two time points (ANOVA, p Conclusions Together, these changes help to illuminate processes and networks involved in abstinence-induced behaviors, including synaptic plasticity, MAPK signaling, and TNF signaling.

    Abstinence-only education has had little demonstrable impact on teenagers' sexual behaviors, despite significant policy and funding efforts. Given the struggle over resources to improve teenagers' reproductive health outcomes, the views of clinicians serving teenagers at high risk for unintended pregnancy and STDs merit particular attention. In 2005, a qualitative study with 31 clinicians serving low-income, at-risk patients was conducted. A semistructured interview guide was used to ask clinicians about adolescent pregnancy, HIV and STD prevention counseling, and when they include abstinence. Thematic content analysis was used to examine the content of the counseling and the techniques used in different situations. Providers reported offering comprehensive counseling, presenting abstinence as a choice for teenagers, along with information about contraceptives and condoms. Several providers mentioned that with young, sexually inexperienced teenagers, they discuss delaying sexual activity and suggest other ways to be affectionate, while giving information on condoms. Providers explained how they assess whether teenagers feel ready to be sexually active and try to impart skills for healthy relationships. Some described abstinence as giving teenagers a way to opt out of unwanted sexual activity. Many support abstinence if that is the patient's desire, but routinely dispense condoms and contraceptives. Overall, providers did not give abstinence counseling as a rigid categorical concept in their preventive practices, but as a health tool to give agency to teenagers within a harm reduction framework. Their approach may be informative for adolescent policies and programs in the future.

    Employment-based reinforcement interventions have been used to promote abstinence from drugs among chronically unemployed injection drug users. The current study used an employment-based reinforcement intervention to promote opioid and cocaine abstinence among opioid and/or cocaine-dependent, HIV-positive participants who had recently completed a brief inpatient detoxification. Participants (n = 46) were randomly assigned to an abstinence and work group that was required to provide negative urine samples in order to enter the workplace and to earn incentives for work (n = 16), a work-only group that was permitted to enter the workplace and to earn incentives independent of drug use (n = 15), and a no-voucher control group that did not receive any incentives for working (n = 15) over a 26-week period. The primary outcome was urinalysis-confirmed opioid, cocaine, and combined opioid/cocaine abstinence. Participants were 78% male and 89% African American. Results showed no significant between-groups differences in urinalysis-verified drug abstinence or HIV risk behaviors during the 6-month intervention. The work-only group had significantly greater workplace attendance, and worked more minutes per day when compared to the no-voucher group. Several features of the study design, including the lack of an induction period, setting the threshold for entering the workplace too high by requiring immediate abstinence from several drugs, and increasing the risk of relapse by providing a brief detoxification that was not supported by any continued pharmacological intervention, likely prevented the workplace from becoming established as a reinforcer that could be used to promote drug abstinence. However, increases in workplace attendance have important implications for adult training programs.

    Advancing marijuana prevention and intervention efforts are important given the decreasing perception of harm among adolescents and increasing marijuana legalization. This study evaluates how a monitored abstinence protocol may contribute to emotional functioning and changes in marijuana problems that can enhance successful outcomes for non-treatment-seeking adolescent marijuana users. Adolescent marijuana users (n = 26) and demographically matched controls (n = 30) completed 28 days of monitored abstinence confirmed by biweekly urine toxicology. Participants were given measures of emotional functioning, marijuana use symptoms, and reward sensitivity during monitored abstinence. All participants (n = 56) completed the protocol, and 69% of marijuana users (n = 18 of 26) were confirmed abstinent for 28 days, with all users showing decreasing marijuana use. Reductions in subsyndromal depression, positive marijuana use expectancies, and poor sleep quality were observed by the end of the monitored abstinence period (n = 26, p values < .05). Marijuana users also reported more attentional impulsivity and less responsiveness to reward stimuli during the second week of abstinence compared to controls. Later age of onset of regular marijuana use and more cumulative lifetime use were associated with a greater degree of emotional change and increased recognition of the negative effects of marijuana use. Monitored abstinence programs may be beneficial in reducing marijuana use, subsyndromal emotional distress symptoms, and changing beliefs about marijuana use. Future prevention and intervention efforts may consider targeting reward sensitivity and impulsivity, in addition to marijuana use, expectancies, and emotional functioning.

    African-American (AA) smokers are at disproportionate risk of tobacco dependence, utilizing smoking to regulate stress, and poor cessation outcomes. Positive emotional traits may function as coping factors that buffer the extent to which dependence increases vulnerability to adverse responses to acute tobacco abstinence (i.e., tobacco withdrawal). This laboratory study examined subjective happiness (SH; dispositional orientation towards frequent and intense positive affect [PA] and life satisfaction) as a moderator of the relation between tobacco dependence and subjective and behavioral abstinence effects among AA smokers. AA smokers (N=420, 39.0% female) completed self-report measures of tobacco dependence and SH followed by two counterbalanced experimental sessions (non-abstinent vs. 16-hr abstinent) involving self-report measures of composite withdrawal, urge to smoke, and mood, and a behavioral smoking task in which participants could: (a) earn money to delay smoking reinstatement, and (b) subsequently purchase cigarettes to smoke. Tobacco dependence was positively associated with increased abstinence effects in composite withdrawal, urge to smoke, PA, and latency to smoking reinstatement (pspsychological construct within tobacco research-subjective happiness-that may suppress the extent to which more severe tobacco dependence increases risk for subjective withdrawal-related distress during acute smoking abstinence in African American smokers. In doing so, the study provides a primer for future targeting of subjective happiness and other positive emotional traits as means to understand and treat acute tobacco abstinence effects among dependent African American smokers. © The Author 2017.

    Although traditional sensitization paradigms, which result in an augmentation of cocaine-induced locomotor behavior and dopamine (DA) overflow following repeated experimenter-delivered cocaine injections, are often used as a model to study drug addiction, similar effects have been difficult to demonstrate following cocaine self-administration. We have recently shown that intermittent access (IntA) to cocaine can result in increased cocaine potency at the DA transporter (DAT); however, traditional sensitization paradigms often show enhanced effects following withdrawal/abstinence periods. Therefore, we determined a time course of IntA-induced sensitization by examining the effects of 1 or 3 days of IntA, as well as a 7-day abstinence period on DA function, cocaine potency, and reinforcement. Here we show that cocaine potency is increased following as little as 3 days of IntA and further augmented following an abstinence period. In addition, IntA plus abstinence produced greater evoked DA release in the presence of cocaine as compared with all other groups, demonstrating that following abstinence, both cocaine's ability to increase DA release and inhibit uptake at the DAT, two separate mechanisms for increasing DA levels, are enhanced. Finally, we found that IntA-induced sensitization of the DA system resulted in an increased reinforcing efficacy of cocaine, an effect that was augmented after the 7-day abstinence period. These results suggest that sensitization of the DA system may have an important role in the early stages of drug abuse and may drive the increased drug seeking and taking that characterize the transition to uncontrolled drug use. Human data suggest that intermittency, sensitization, and periods of abstinence have an integral role in the process of addiction, highlighting the importance of utilizing pre-clinical models that integrate these phenomena, and suggesting that IntA paradigms may serve as novel models of human addiction.

    Past research suggests that a significant relationship exists between cigarette smoking and illicit-stimulant abuse. The present study evaluated the association between achieving smoking abstinence in response to smoking-cessation treatment (SCT) and illicit-stimulant abstinence in cocaine- and/or methamphetamine-dependent participants. Secondary analysis of a randomized, 10-week trial conducted at 12 substance use disorder (SUD) treatment programs. Two hundred and sixty seven adults, meeting DSM-IV-TR criteria for cocaine and/or methamphetamine-dependence and interested in quitting smoking were randomized to SUD treatment as usual plus SCT consisting of weekly individual smoking cessation counseling, extended-release (XL) bupropion (300 mg/day), nicotine inhaler, and contingency management for smoking abstinence. Illicit-stimulant-abstinence was measured by self-report and urine drug screens. Smoking abstinence was assessed via self-report and carbon monoxide levels. A significant effect was found for the cocaine-dependent subsample (N=147) in which participants who stopped smoking were abstinent for illicit stimulants an average of 78.2% of the post-smoking-quit weeks (weeks 4-10) relative to 63.6% in participants who continued smoking (X(2)(1)=8.55, p<.01, d=0.36). No significant effects were found for the sample as a whole (N=249) or for the methamphetamine-dependent subsample (N=102). The present results suggest that cocaine-dependent patients achieving smoking abstinence in response to SCT might evidence not only improved smoking outcomes but improved cocaine-use outcomes as well. Future research to replicate this finding appears warranted. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    This secondary data analysis sought to determine what mediated reductions in self-reported sexual initiation over the 24-month postintervention period in early adolescents who received "Promoting Health among Teens," a theory-based, abstinence-only intervention (Jemmott, Jemmott, & Fong, 2010). African American Grade 6 and 7 students at inner-city public middle schools were randomized to 1 of 5 interventions grounded in social-cognitive theory and the theory of reasoned action: 8-hr abstinence-only targeting reduced sexual intercourse; 8-hr safer-sex-only targeting increased condom use; 8-hr and 12-hr comprehensive interventions targeting sexual intercourse and condom use; 8-hr control intervention targeting physical activity and diet. Primary outcome was self-report of vaginal intercourse by 24 months postintervention. Potential mediators, assessed immediately postintervention, were theory-of-reasoned-action variables, including behavioral beliefs about positive consequences of abstinence and negative consequences of sex, intention to have sex, normative beliefs about sex, and HIV and sexually transmitted infection (STI) knowledge. We tested single and serial mediation models using the product-of-coefficients approach. Of 509 students reporting never having vaginal intercourse at baseline (324 girls and 185 boys; mean age = 11.8 years, SD = 0.8), 500 or 98.2% were included in serial mediation analyses. Consistent with the theory of reasoned action, the abstinence-only intervention increased positive behavioral beliefs about abstinence, which reduced intention to have sex, which in turn reduced sexual initiation. Negative behavioral beliefs about sex, normative beliefs about sex, and HIV/STI knowledge were not mediators. Abstinence-only interventions should stress the gains to be realized from abstinence rather than the deleterious consequences of sexual involvement. (c) 2015 APA, all rights reserved).

    Full Text Available Preventing relapse to drug abuse is one of the struggles faced by clinicians in order to treat patients with substance use disorders (DSM-5. There is a large body of clinical evidence suggesting differential characteristics of the disorder in men and women which is in line with preclinical findings as well. The aim of this study was to assess differences in relapse-like behavior in methamphetamine (METH seeking after a period of forced abstinence which simulates the real clinical situation very well. Findings from such study might add new insights in gender differences in relapse mechanisms to previous studies, which employ a classical drug or cue-induced reinstatement procedure following the extinction training.Adult male and female Sprague-Dawley rats were used in IV self-administration procedure conducted in operant boxes using nose-poke operandi (Coulborn Instruments, USA. Active nose-poke resulted in activation of the infusion pump to deliver one intravenous infusion of METH (0.08 mg/kg. After baseline drug intake was established (maintenance phase, a period of forced abstinence was initiated and rats were kept singly in their home-cages for 14 days. Finally, one reinstatement session in operant boxes was conducted. Females were found to self-administer significantly lower dose of METH. The relapse rate was assessed as a number of active nose-pokes during the reinstatement session, expressed as a percentage of active nose-poking during the maintenance phase. Females displayed approximately 300 % of active nose-pokes compared to 48 % in males. This indicates higher vulnerability to relapse of METH seeking behavior in female rats. This effect was detected in all females, independently of current phase of their estrous cycle. Therefore, this paradigm using operant drug self-administration and reinstatement of drug-seeking after forced abstinence model can be used for preclinical screening for potential new anti-relapse medications specific for

    Relapse is a hallmark feature of cocaine addiction and a main challenge for treatment strategies. Human studies indicate a link between impulsivity and increased susceptibility to relapse. Rats were screened for high (HI) and low impulsivity (LI) on the 5-choice serial reaction time task. The HI and LI rats were trained to self-administer cocaine under a seeking-taking chained schedule: responses on the seeking lever resulted in presentation of the taking lever, responding upon which resulted in cocaine reinforcement. After the establishment of stable responding, an intermittent punishment schedule was introduced: completion of the seeking link resulted in the random presentation of either the taking lever or a mild footshock. This resulted in a progressive decrease in cocaine-seeking approaching abstinence. Relapse was assessed 7 days after punishment, during which responding on the seeking lever resulted in the presentation of the cocaine-associated stimuli (i.e., in the absence of cocaine or footshock). The HI and LI animals significantly reinstated the cocaine-seeking response after a single phase of seeking punishment. However, after a second punishment phase only the HI rats reinitiated suppressed seeking responses and relapsed, an effect that was facilitated by prior extended cocaine access. In a preliminary study we found that the selective noradrenaline reuptake inhibitor, atomoxetine, a drug known to reduce impulsivity, prevented the reinstatement of cocaine-seeking. Impulsivity pre-dating drug abuse increases the susceptibility to relapse after abstinence. Medications targeting impulsivity might have utility as treatment interventions for relapse prevention and the promotion of abstinence.

    Full Text Available Objectives: To investigate the effects of ever use of electronic cigarettes (ECs, many of which lack nicotine, on abstinence from convention cigarettes among Hong Kong adult smokers. Methods: We collected data from 956 daily smokers in 2014–2015 regarding ever EC use and smoking behaviors at baseline, any and past 30-day EC use at the 3-month follow-up. Outcomes measured at 6 months included past 7-day point prevalence abstinence (PPA, biochemically validated quitting, smoking reduction (≥50% from baseline and cessation attempt. Logistic regression yielded adjusted odds ratios (AOR for quitting in relation to EC use, adjusting for socio-demographic characteristics and smoking profile. Complete case, missing observation as smoking and propensity score analyses were conducted. Results: By complete case, ever EC use at baseline did not predict self-reported PPA (AOR 0.99, 95% CI 0.57–1.73, biochemically validated quitting (AOR 1.22, 95% CI 0.64–2.34, cessation attempt (AOR 0.74, 95% CI 0.48–1.14, or smoking reduction (AOR 0.89, 95% CI 0.54–1.47. EC use during the first 3 months did not predict quitting (AOR 1.02, 95% CI 0.22–4.71. Similar results were observed for missing observations as smoking and propensity score analyses. Conclusions: Any use of ECs, many of which lack nicotine, did not predict smoking abstinence among Hong Kong adult smokers.

  18. Effects of abstinence and family history for alcoholism on platelet adenylyl cyclase activity.

    1998-12-01

    Platelet adenylyl cyclase (AC) activity was measured in 32 alcohol-dependent subjects and 27 control subjects who were categorized as either family history-positive (FHP) or family history-negative (FHN) for alcoholism. The interview and blood sample collections were performed shortly after cessation of heavy drinking in the alcoholic group, and repeat blood samples were obtained at the end of the first and second weeks of monitored abstinence. Control subjects received the same interview and provided blood samples at the time of the interview. When subjects were not segregated for FHP or FHN status, there were no statistically significant differences in basal, cesium fluoride (CsF)-, or forskolin-stimulated mean AC activities between the controls and the alcoholics, at study entry or with 1 or 2 weeks of abstinence. On the other hand, over the 2-week course of sobriety from heavy drinking, the CsF-stimulated AC activity of FHP alcohol-dependent subjects decreased significantly (p = 0.03). FHP alcohol-dependent subjects after 2 weeks of sobriety had significantly lower mean CsF-stimulated AC activity than FHN controls (p = 0.04), whereas the FHN alcoholic subjects' CsF-stimulated AC activity did not differ significantly from FHN controls at this point in time. When all subjects were pooled and then categorized as either FHP or FHN, there was a significant difference in mean CsF-stimulated AC activity (p = 0.02) between the FHP and FHN subject groups. Genetic factors and abstinence appear to have roles in determining low platelet AC activity in alcoholic and nonalcoholic subjects. CsF-stimulated platelet AC activity, in particular, appears to act as a trait marker for a genetic vulnerability to developing alcoholism, but recent heavy drinking in male alcoholics is a factor that can mask differences between FHP and FHN subjects.

    Smoking during pregnancy increases the risk of many adverse health outcomes for both the mother and the unborn child (Morton et al. 2010). Indigenous people often have a higher smoking prevalence during pregnancy than non-Indigenous populations. In New Zealand (NZ), the smoking rates among Indigenous Māori women who are pregnant have reduced since 1991 (68 %) but still remains high in 2007 (34 %) (Morton et al. 2010). The success rate of most smoking cessation interventions for pregnant smokers is low at products and services, and access to nicotine replacement therapy (control), (2) usual cessation support plus a retail voucher to the value of NZ$25 for each 'abstinent from smoking' week for 8 weeks (voucher), or (3) usual cessation support plus product to the value of NZ$25 for each 'abstinent from smoking' week for 8 weeks (product). Outcomes measures included weekly self-reported and monthly biochemically verified smoking status, and acceptability. Of the 74 referred women, 50 declined involvement in the study and 24 consented and were randomised (eight control, eight voucher and eight to product). The mean age of participants was 25 years old (±2.25). Overall 21 % (n = 5) of the women were abstinent from smoking for at least 6 weeks of the eight, one from the control, six from the product and three from the voucher. Our findings suggest that incentives, in particular a choice of products, may be an effective addition to usual care to increase smoking cessation among pregnant Māori women, which has the potential to improve health outcomes for both the mother and child.

  20. MISH publishes new framework for fear-based, abstinence-only education.

    Science.gov (United States)

    Mayer, R

    1997-01-01

    The US Medical Institute for Sexual Health (MISH) "National Guidelines for Sexuality and Character Education" is a fear-based, abstinence-only framework for sexuality education. This document is virtually identical in format, conceptual framework, and typeface to that produced by the Sexuality Information and Education Council of the United States (SIECUS) and adopts SIECUS language in many sections. SIECUS agrees with approximately 60% of the MISH messages and finds it noteworthy that the MISH guidelines provide a blueprint for sex education from elementary school through high school. However, MISH and SIECUS follow very different approaches to sex education. SIECUS seeks to help young people acquire the necessary information to safeguard their sexual health and make proper decisions, while the single goal of MISH is to promote abstinence until marriage (avoiding sexual intercourse and any activity involving genital contact or stimulation). MISH promotes this view with fear-based messages, uses only negative terms to describe adolescent sexual relations, and provides scant and misleading information about contraception (including the assertion that adolescent use of birth control is often ineffective). The MISH curriculum also promotes the anti-abortion viewpoint that life begins at conception. While acknowledging the changing composition of the US family, MISH promotes a view of the nuclear family as the "best" type of family in which to rear children. MISH skirts the issue of sexual orientation and avoids giving information about ways to seek treatment for sexually transmitted diseases or prenatal care. MISH guidelines make unsubstantiated statements about the value of abstinence, provide almost no information about how to adapt their framework to various communities, discuss contraceptives and condoms only in terms of failures, and suggest that all adolescent sexual relations have negative consequences.

  1. Exclusive purpose: abstinence-only proponents create federal entitlement in welfare reform.

    Science.gov (United States)

    Daley, D

    1997-01-01

    Since 1981, the US government has funded a program promoting sexual abstinence among young people through its Office of Population's Adolescent Family Life Demonstration Grants program (AFLA). A 1983 court challenge which held that AFLA violated the separation of church and state by endorsing a particular religious viewpoint was settled out of court in 1993 with stipulations that AFLA-funded sexuality education must not include religious references, must be medically accurate, must respect the principle of self-determination of teenagers regarding contraceptive referrals, and must not be implemented on church property. Critics continue to charge that AFLA's abstinence-only programs have failed to receive proper evaluation. While AFLA has no broad-based support, it is backed by the same small group of Congressional proponents who are attempting to promote broad-scale, federally-funded abstinence-only programs. Thus, the August 1996 welfare reform legislation represents the broadest attack on the provision of comprehensive sexuality education in the US. While opponents of sexuality education could not restrict the content of education programs, they could restrict programs through health policy and funding mechanisms. Congress, thus, mandated $50 million a year for 1998-2002 to a matching grant with entitlement status, which was tagged on to final versions of the larger welfare reform bill. The intent of this action was to use federal law to change the social norm of premarital sexual activity. Funds will not go to programs which discuss contraception. Additional problems with the statute include misinformation, ambiguity, and a lack of evaluation requirements. It remains for states to decide whether to accept the restricted funds and for parties on both sides of the issue to continue to lobby for their positions.

    Alcohol and drug use results in substantial morbidity, mortality, and cost. Individuals with alcohol and drug use disorders are overrepresented in general medical settings. Hospital-based interventions offer an opportunity to engage with a vulnerable population that may not otherwise seek treatment. To determine whether inpatient addiction consultation improves substance use outcomes 1 month after discharge. Prospective quasi-experimental evaluation comparing 30-day post-discharge outcomes between participants who were and were not seen by an addiction consult team during hospitalization at an urban academic hospital. Three hundred ninety-nine hospitalized adults who screened as high risk for having an alcohol or drug use disorder or who were clinically identified by the primary nurse as having a substance use disorder. Addiction consultation from a multidisciplinary specialty team offering pharmacotherapy initiation, motivational counseling, treatment planning, and direct linkage to ongoing addiction treatment. Addiction Severity Index (ASI) composite score for alcohol and drug use and self-reported abstinence at 30 days post-discharge. Secondary outcomes included 90-day substance use measures and self-reported hospital and ED utilization. Among 265 participants with 30-day follow-up, a greater reduction in the ASI composite score for drug or alcohol use was seen in the intervention group than in the control group (mean ASI-alcohol decreased by 0.24 vs. 0.08, p drug decreased by 0.05 vs. 0.02, p = 0.003.) There was also a greater increase in the number of days of abstinence in the intervention group versus the control group (+12.7 days vs. +5.6, p drug, and days abstinent all remained statistically significant after controlling for age, gender, employment status, smoking status, and baseline addiction severity (p = 0.018, 0.018, and 0.02, respectively).

    Full Text Available The identification of growth factors as potential biomarkers in alcohol addiction may help to understand underlying mechanisms associated with the pathogenesis of alcohol use disorders (AUDs. Previous studies have linked growth factors to neural plasticity in neurocognitive impairment and mental disorders. In order to further clarify the impact of chronic alcohol consumption on circulating growth factors, a cross-sectional study was performed in abstinent AUD patients (alcohol group, N = 91 and healthy control subjects (control group, N = 55 to examine plasma concentrations of brain-derived neurotrophic factor (BDNF, insulin-like growth factor-1 (IGF-1 and IGF-1 binding protein-3 (IGFBP-3. The association of these plasma peptides with relevant AUD-related variables and psychiatric comorbidity was explored. The alcohol group was diagnosed with severe AUD and showed an average of 13 years of problematic use and 10 months of abstinence at the moment of participating in the study. Regarding common medical conditions associated with AUD, we observed an elevated incidence of alcohol-induced liver and pancreas diseases (18.7% and psychiatric comorbidity (76.9%. Thus, AUD patients displayed a high prevalence of dual diagnosis (39.3% [mainly depression (19.9%] and comorbid substance use disorders (40.7%. Plasma BDNF and IGF-1 concentrations were significantly lower in the alcohol group than in the control group (p<0.001. Remarkably, there was a negative association between IGF-1 concentrations and age in the control group (r = -0.52, p<0.001 that was not found in the alcohol group. Concerning AUD-related variables, AUD patients with liver and pancreas diseases showed even lower concentrations of BDNF (p<0.05. In contrast, the changes in plasma concentrations of these peptides were not associated with abstinence, problematic use, AUD severity or lifetime psychiatric comorbidity. These results suggest that further research is necessary to elucidate the

    Full Text Available The aim of this study was to examine the factors related to abstinence from heroin and methamphetamine (MAMP use and to seeking help from medical services in Taiwanese drug users. Atotal of 196 heroin users and 226 MAMP users were recruited in this study. Their experience of previous abstinence from drug use and the routes taken to seek help for abstinence were determined at interview. Demographic data, characteristics of drug use and reasons to abstain from drug use were compared between subjects who had and those who had never tried to abstain from drug use before, as well as between the subjects who had previously sought help from medical services and those who had tried to abstain from drug use by themselves. Those who had previously tried to abstain from heroin use had longer durations of heroin use, spent more money on getting heroin, were more likely to have a criminal record of illicit drug use and had longer durations of being detained due to illicit drug use compared with those who had never tried to abstain from heroin use. Those who had sought help from medical services for abstinence were more likely to be heroin users and to spend more money on getting illicit drugs, and tried to abstain due to concerns about relationships with family. Demographic data, characteristics of drug use and reasons to abstain from drug use were different between drug users who had different experiences of abstinence.

    Full Text Available AbstractDrug addiction is viewed as a maladaptive memory induced by contextual cues even in the abstinent state. However, the variations of hedonia and appetite induced by the context during the abstinence have been neglected. To distinguish the representative behaviors between hedonia and appetite, micro-behaviors in abstinent animal such as psycho-activity and drug seeking behaviors were observed in morphine conditioned place preference (CPP. To confirm the different effects of reward between drug and natural reward, a palatable food CPP paradigm was compared in current work. After a 10-day training in CPP with morphine or food, the preference was tested on day 1, 14, 28, and the changes of micro-behaviors were analyzed further. Our data showed that tree shrews treated with morphine performed more jumps on day 1 and more visits to saline paired side on day 28, which indicated a featured behavioral transition from psycho-activity to seeking behavior during drug abstinence. Meanwhile, food-conditioned animals only displayed obvious seeking behaviors in the three tests. The results suggest that the variations of micro-behaviors could imply such a transition from hedonic response to appetitive behaviors during morphine abstinence, which provided a potential behavioral basis for further neural mechanism studies.

    Studies assessing withdrawal phenomenon during short-term abstinence from chronic cocaine use have been limited. Although cocaine abusers are reported to be at increased risk for cardiac disorders, little research has assessed cardiac parameters in cocaine abusers and subsequent changes in these parameters that may be associated with the discontinuation of cocaine use. In this study, we categorize 441 chronic cocaine abusers into three groups based on self-reported length of abstinence from cocaine use at entry into a trial approved by the National Institute on Drug Abuse (NIDA) assessing the use of pergolide mesylate in treating relapse and craving in crack cocaine abuse. Electrocardiogram (ECG) PR intervals were found to be correlated positively with length of abstinence, returning to normal population levels within 30 days. In addition, levels of generalized anxiety, nervousness, and heart racing were found to be correlated negatively with length of abstinence from crack cocaine. This work provides preliminary evidence of cardiac and mood-related parameters that are associated with cocaine abstinence and that may indicate specific withdrawal phenomena in chronic users. In addition, these results suggest that the risk of cardiomyopathies associated with abnormal atrial-ventricular polarization may dissipate relatively quickly in abusing individuals.

    Full Text Available Os fundos setoriais foram instituídos no final da década de 1990, com o propósito de criar condições mais estáveis de financiamento público às atividades de ciência, tecnologia e inovação (CT&I no Brasil. De maneira análoga ao que se observa com outros instrumentos de incentivo à inovação nas empresas, a expectativa é que o acesso aos fundos setoriais contribuiria para o aumento dos esforços tecnológicos e para o alcance de melhores resultados pelas empresas. O objetivo deste trabalho é, portanto, avaliar o impacto desses fundos sobre os esforços tecnológicos e sobre os resultados das empresas industriais no Brasil, no período 2001 a 2006. A base teórica para a discussão é a literatura internacional que tem, recorrentemente, analisado o efeito crowding in ou crowding out de políticas de apoio à inovação nas empresas. Esses trabalhos buscam verificar se as políticas adotadas complementam os recursos alocados nas atividades de inovação pelas empresas ou se haveria simplesmente a substituição desses últimos por recursos públicos. Neste artigo, uma técnica quasi-experimental é aplicada para comparar as empresas que acessaram os fundos setoriais com aquelas que não os acessaram, usando dados de painel que incluem informações sobre esforços tecnológicos e resultados. O grupo de controle é definido com base no algoritmo de Propensity Score Matching (PSM, visando eliminar o viés de seleção no acesso aos fundos, o que faz com que, a priori, as empresas que acessam esses recursos trilhem uma trajetória distinta daquelas que não acessam. Estimativas das diferenças percentuais das taxas de crescimento dos esforços tecnológicos indicam significativo descolamento entre os grupos de tratamento e controle e permitem que se rejeite a hipótese de crowding out. Estima-se que o diferencial na taxa de crescimento do PoTec – que corresponde à proxy para os esforços tecnológicos – seja de 6,8 p.p. no primeiro

    This study evaluated a novel drug abuse treatment, the Therapeutic Workplace. In this treatment, patients are paid to perform jobs or to participate in job training. Salary is linked to abstinence by requiring patients to provide drug-free urine samples to gain access to the workplace. Pregnant and postpartum drug abuse patients (N = 40) were randomly assigned to a Therapeutic Workplace or usual care control group. Therapeutic Workplace participants were invited to work 3 hr every weekday for 6 months and could earn up to $4,030 in vouchers for abstinence, workplace attendance, and performance. On average, 45% of participants attended the workplace per day. Relative to controls, the Therapeutic Workplace nearly doubled patients' abstinence from opiates and cocaine (33% vs. 59% of thrice-weekly urine samples drug negative, respectively, p Workplace can effectively treat heroin and cocaine abuse in pregnant and postpartum women.

    Cue-induced methamphetamine craving increases after prolonged forced (experimenter-imposed) abstinence from the drug (incubation of methamphetamine craving). Here, we determined whether this incubation phenomenon would occur under conditions that promote voluntary (self-imposed) abstinence. We also determined the effect of the novel metabotropic glutamate receptor 2 positive allosteric modulator, AZD8529, on incubation of methamphetamine craving after forced or voluntary abstinence. We trained rats to self-administer palatable food (6 sessions) and then to self-administer methamphetamine under two conditions: 12 sessions (9 hours/day) or 50 sessions (3 hours/day). We then assessed cue-induced methamphetamine seeking in extinction tests after 1 or 21 abstinence days. Between tests, the rats underwent either forced abstinence (no access to the food- or drug-paired levers) or voluntary abstinence (achieved via a discrete choice procedure between methamphetamine and palatable food; 20 trials per day) for 19 days. We also determined the effect of subcutaneous injections of AZD8529 (20 and 40 mg/kg) on cue-induced methamphetamine seeking 1 day or 21 days after forced or voluntary abstinence. Under both training and abstinence conditions, cue-induced methamphetamine seeking in the extinction tests was higher after 21 abstinence days than after 1 day (incubation of methamphetamine craving). AZD8529 decreased cue-induced methamphetamine seeking on day 21 but not day 1 of forced or voluntary abstinence. We introduce a novel animal model to study incubation of drug craving and cue-induced drug seeking after prolonged voluntary abstinence, mimicking the human condition of relapse after successful contingency management treatment. Our data suggest that positive allosteric modulators of metabotropic glutamate receptor 2 should be considered for relapse prevention. Published by Elsevier Inc.

    Abstinence from smoking on the morning of surgery may improve outcomes. This study examined the explicatory power of the Theory of Planned Behavior (TPB) to predict smoking behavior on the morning of surgery, testing the hypothesis that the constructs of attitude, subjective norm, and perceived behavioral control (PBC) will predict intent to abstain from smoking the morning of surgery, and that intent will predict behavior. TPB constructs were assessed in 169 pre-surgical patients. Smoking behavior on the morning of surgery was assessed by self-report and CO monitoring. Correlations and structural equation modeling (SEM) were used to determine associations between measures and behavior. All TPB measures, including intent as predicted by the TPB, were correlated with both a lower rate of self-reported smoking on the morning of surgery and lower CO levels. The SEM showed a good fit to the data. In the SEM, attitude and PBC, but not subjective norm, were significantly associated with intent to abstain, explaining 46% of variance. The effect of PBC on CO levels was partially mediated by intent. The amount of variance in behavior explained by these TPB constructs was modest (10% for CO levels). Thus, attitude and perceived behavioral control explain a substantial portion of the intent to maintain preoperative abstinence on the morning of elective surgery, and intent and perceived behavioral control explain a more modest but significant amount of the variance in actual smoking behavior.

    To investigate changes in social network and quality of life of a substance use disorder cohort as they progressed through treatment. Multi-site, prospective, observational study of 338 adults entering substance use disorder treatment. Patients at 21 facilities across Norway contributed baseline data when they initiated treatment, and follow-up data was collected from them one year later. The cohort was divided into those who completed, dropped out, and remained in treatment one year after treatment initiation. For each treatment status group, general linear models with repeated measures analyzed global and social quality of life with the generic QOL10 instrument over time. The between-group factor was a change in social network variable from the EuropASI. Those who gained an abstinent network reported the largest quality of life improvements. Improvements were smallest or negligible for the socially isolated and those who were no longer in contact with the treatment system. Developing an abstinent network is particularly important to improve the quality of life of those in substance use disorder treatment. Social isolation is a risk factor for impaired quality of life throughout the treatment course. Copyright © 2017 Elsevier B.V. All rights reserved.

    It has been reported that chronic heroin intake induces both structural and functional changes in human brain; however, few studies have investigated the carry-over adverse effects on brain after heroin withdrawal. In this paper, we examined the neurophysiological differences between the abstinent heroin addicts (AHAs) and healthy controls (HCs) using nonlinear dynamic analysis and source localization analysis in resting-state electroencephalogram (EEG) data; 5 min resting EEG data from 20 AHAs and twenty age-, education-, and gender-matched HCs were recorded using 64 electrodes. The results of nonlinear characteristics (e.g., the correlation dimension, Kolmogorov entropy, and Lempel-Ziv complexity) showed that the EEG signals in alpha band from AHAs were significantly more irregular. Moreover, the source localization results confirmed the neuronal activities in alpha band in AHAs were significantly weaker in parietal lobe (BA3 and BA7), frontal lobe (BA4 and BA6), and limbic lobe (BA24). Together, our analysis at both the sensor level and source level suggested the functional abnormalities in the brain during heroin abstinence, in particular for the neuronal oscillations in alpha band.

    Urgent measures are required to stop the increase in the frequency of pregnancies and sexually transmitted diseases among teenagers. A means of facing this problem is promoting sexual abstinence among youngsters. There are studies that confirm the efficacy of this approach. To show the results of the application of a holistic sexuality program (TeenSTAR) among Chilean teenagers. Students attending basic or high school were divided into a control or study group. The control group (342 students) received the usual education on sexuality given by their schools and the study group (398 students) participated in twelve TeenSTAR sessions lasting 1.5 hours each, given by a trained professor. Assessment of achievements was made using an anonymous questionnaire answered at the start and end of the program. The rates of sexual initiation among control and study groups were 15 and 6.5%, respectively. Among sexually active students, 20% of those in the study group and 9% of those in the control group discontinued sexual activity. A higher proportion of students in the TeenSTAR program retarded their sexual initiation or discontinued sexual activity and found more reasons to maintain sexual abstinence than control students.

    Prior research suggests that abrupt initiation of abstinence from cigarette smoking reduces neural cognitive efficiency. When cognitive efficiency is high, processing speed and accuracy are maximized with minimal allocation of cognitive resources. The study presented here tested the effects of resumption of smoking on cognitive response conflict after overnight abstinence from smoking, hypothesizing that smoking would enhance cognitive efficiency. Twenty paid research volunteers who were chronic cigarette smokers abstained from smoking overnight (>12 h) before undergoing fMRI while performing a color-word Stroop task during two separate test sessions: one that did not include smoking before testing and another one that did. Statistical analyses were performed by modeling the Stroop effect (incongruent >congruent) BOLD response within a collection of a priori regions of interest that have consistently been associated with cognitive control. Behavioral assessment alone did not reveal any significant differences in the Stroop effect between the two sessions. BOLD activations, however, indicated that in the right anterior cingulate cortex (ACC), smokers had significantly less task-related activity following smoking (pconflict activity together with improvement in conflict resolution involving the dorsolateral prefrontal cortex.

    Much is known about the predictors of success in quitting smoking. In particular, nicotine dependence, but not strength of motivation to stop, appears to predict abstinence. However, to date, studies have come almost exclusively from Western countries. More data are needed on the cross-cultural generalizability of these findings. One hundred and ninety-eight smokers attending 5 stop-smoking clinics in Malaysia completed a questionnaire prior to their target quit date and were followed up 3 months after this date. Predictors included sociodemographic variables, smoking patterns, past history of quitting, characteristics of current quit attempt, and smoking motives as well as nicotine dependence (Fagerström Test for Nicotine Dependence [FTND]) and self-rated strength of motivation of stop. At 3-month follow-up, 35.4% (95% CI: 28.7-42.0) of participants reported being abstinent. A backward elimination multiple logistic regression identified a number of significant predictors of success, including strength of motivation to stop (adjusted odds ratio [OR]: 3.05, 95% CI: 1.28-7.25). FTND did not predict success. Motivation and nicotine dependence may play different roles in explaining variation in ability to stop smoking in different cultures.

    Attenuation of adrenergic drive and cognitive enhancement, via stimulation of alpha2 pre- and post-synaptic receptors, may selectively enhance executive performance in early abstinent cocaine-dependent individuals. As these cognitive processes underpin important treatment-related behaviors, the alpha2 agonist, guanfacine HCl, may represent an effective pharmaco-therapeutic intervention. Twenty-five early abstinent cocaine-dependent individuals were administered a battery of neurocognitive tasks on entry into treatment (baseline) and again following 3 weeks of either placebo or guanfacine treatment (up to 3 mg). Tasks included: Stop Signal, Stroop, 3-Dimentional Intra-dimensional/Extra-dimensional (IDED) task, Spatial Working Memory (SWM), Paired Associates Learning (PAL), Verbal Fluency and the Rey Auditory Verbal Learning Test (RAVLT). Compared with placebo, the guanfacine group demonstrated attenuated anxiety and negative affect as well as improved performance on selective executive tests. This included fewer directional errors on the stop signal task, fewer errors on the extra-dimensional shift component of the IDED task and better attentional switching during verbal fluency. Guanfacine did not improve strategic working memory or peripheral memory. Guanfacine improves selective cognitive processes which may underlie salient treatment-related regulatory behaviors. Alpha2 agonists may therefore represent important agents for cocaine dependence. © The Author(s) 2015.

    In human alcoholics, abstinence is often self-imposed, despite alcohol availability, because of the negative consequences of excessive use. During abstinence, relapse is often triggered by exposure to contexts associated with alcohol use. We recently developed a rat model that captures some features of this human condition: exposure to the alcohol self-administration environment (context A), after punishment-imposed suppression of alcohol self-administration in a different environment (context B), provoked renewal of alcohol seeking in alcohol-preferring P rats. The mechanisms underlying context-induced renewal of alcohol seeking after punishment-imposed abstinence are unknown. Here, we studied the role of the lateral hypothalamus (LH) and its forebrain projections in this effect. We first determined the effect of context-induced renewal of alcohol seeking on Fos (a neuronal activity marker) expression in LH. We next determined the effect of LH reversible inactivation by GABAA + GABAB receptor agonists (muscimol + baclofen) on this effect. Finally, we determined neuronal activation in brain areas projecting to LH during context-induced renewal tests by measuring double labeling of the retrograde tracer cholera toxin subunit B (CTb; injected in LH) with Fos. Context-induced renewal of alcohol seeking after punishment-imposed abstinence was associated with increased Fos expression in LH. Additionally, renewal was blocked by muscimol + baclofen injections into LH. Finally, double-labeling analysis of CTb + Fos showed that context-induced renewal of alcohol seeking after punishment-imposed abstinence was associated with selective activation of accumbens shell neurons projecting to LH. The results demonstrate an important role of LH in renewal of alcohol seeking after punishment-imposed abstinence and suggest a role of accumbens shell projections to LH in this form of relapse.

    Abstinence reinforcement is efficacious for improving smoking treatment outcomes, but practical constraints related to the need for multiple in-person carbon monoxide (CO) breath tests daily to verify smoking abstinence have limited its use. This study tested an mHealth procedure to remotely monitor and reinforce smoking abstinence in individuals' natural environment. Eligible treatment-seeking smokers (N = 90) were randomized to (1) usual care and ecological monitoring with abstinence reinforcement (mHealth reinforcement) or (2) without reinforcement (mHealth monitoring). Usual care was 8 weeks of transdermal nicotine and twice-weekly telephone counseling. Following training, an interactive voice response system prompted participants to conduct CO tests 1-3 daily at pseudorandom times (7 am to 10 pm) for 4 weeks. When prompted, participants used a study cell phone and CO monitor to complete a CO self-test, video record the process, and submit videos using multimedia messaging. mHealth reinforcement participants could earn prizes for smoking-negative on-time CO tests. The interactive voice response generated preliminary earnings immediately. Earnings were finalized by comparing video records against participants' self-reports. mHealth reinforcement was associated with a greater proportion of smoking-negative CO tests, longest duration of prolonged abstinence, and point-prevalence abstinence during the monitoring/reinforcement phase compared to mHealth monitoring (p < .01, d = 0.8-1.3). Follow-up (weeks 4-24) analyses indicated main effects of reinforcement on point-prevalence abstinence and proportion of days smoked (p ≤ .05); values were comparable by week 24. mHealth reinforcement has short-term efficacy. Research on methods to enhance and sustain benefits is needed. This study suggests that mHealth abstinence reinforcement is efficacious and may present temporal and spatial opportunities to research, engage, and support smokers trying to quit that do not exist

The Drinking-Related Cognitions Scale (DRCS is a new self-reported rating scale developed to briefly measure cognitive factors associated with drinking behavior in alcohol-dependent patients under abstinence-oriented treatment, including positive alcohol expectancies, abstinence self-efficacy, perception of impaired control over drinking, and perception of drinking problems. Here, we conducted a prospective cohort study to explore the predictive validity of DRCS. Methods Participants in this study were 175 middle-aged and elderly Japanese male patients who met the DSM-IV Diagnostic Criteria for Alcohol Dependence. DRCS scores were recorded before and after the inpatient abstinence-oriented treatment program, and treatment outcome was evaluated one year after discharge. Results Of the 175 participants, 30 were not available for follow-up; thus the number of subjects for analysis in this study was 145. When the total DRCS score and subscale scores were compared before and after inpatient treatment, a significant increase was seen for both scores. Both the total DRCS score and each subscale score were significantly related to total abstinence, percentage of abstinent days, and the first drinking occasion during the one-year post-treatment period. Therefore, good treatment outcome was significantly predicted by low

    Social characteristics associated with disadvantage, such as racial/ethnic minority status, female gender, and low socioeconomic status (SES), are often associated with increased psychological distress and substance use disorders. This project tests a conceptual model derived from Pearlin's social stress theory for predicting abstinence from substance use between baseline and 1-year follow-up in secondary data from a large statewide sample of Kentucky substance abuse treatment participants (N = 1,123). Racial minority status, employment, and higher education level were predictive of substance use at follow-up, while female gender was predictive of abstinence. Limitations, implications for practice, and suggestions for future research are discussed.

    Determine if employment-based reinforcement can increase methadone treatment engagement and drug abstinence in out-of-treatment injection drug users. This study was conducted from 2008 to 2012 in a therapeutic workplace in Baltimore, MD. After a 4-week induction, participants (N=98) could work and earn pay for 26 weeks and were randomly assigned to Work Reinforcement, Methadone & Work Reinforcement, and Abstinence, Methadone & Work Reinforcement conditions. Work Reinforcement participants had to work to earn pay. Methadone & Work Reinforcement and Abstinence, Methadone, & Work Reinforcement participants had to enroll in methadone treatment to work and maximize pay. Abstinence, Methadone, & Work Reinforcement participants had to provide opiate- and cocaine-negative urine samples to maximize pay. Most participants (92%) enrolled in methadone treatment during induction. Drug abstinence increased as a graded function of the addition of the methadone and abstinence contingencies. Abstinence, Methadone & Work Reinforcement participants provided significantly more urine samples negative for opiates (75% versus 54%) and cocaine (57% versus 32%) than Work Reinforcement participants. Methadone & Work Reinforcement participants provided significantly more cocaine-negative samples than Work Reinforcement participants (55% versus 32%). The therapeutic workplace can promote drug abstinence in out-of-treatment injection drug users. Clinical trial registration number: NCT01416584. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available The goals of the Abstinence and Be Faithful Among Youth (ABY project were to enhance local responses among the youth in South Africa to prevent HIV infection through encouraging abstinence,faithfulness and avoidance of unhealthy sexual behaviour among youths over a five-year period. A quantitative baseline evaluation of the ABY project was conducted in five cities in South Africa. Data were collected from learners and youths just before the ABY intervention started at nine randomly selected sites in Johannesburg, Cape Town, Durban, Port Elizabeth and Mthatha using a three-stage cluster sampling design. In total, nine sites were randomly selected from a possible eighteen. At each of the data-collection points, data were collected from 60 participants. In total there were 27 data-collection points and 1620 respondents. Young people have strong views on abstaining from sexual intercourse, as 83% said that it was possible not to have sex for as long as you can. There was also strong support for abstinence, as 78.5% said that not having sex was the best way of preventing infection with HIV. In total, 68.1% of the youths said that the media had a positive influence on encouraging abstinence and 72.1% said role models could help them not to have sex, while 84.3% said that leadership and life skills workshops were helpful in encouraging them to abstain from sex. In total, 68.7% of young people said that the media encouraged faithfulness in relationships and 84.6% said that life skills workshops were helpful in encouraging them to remain faithful to one partner. Young people have strong views on and support for abstinence. They also have strong views on and perceptions of remaining faithful to one partner. These findings are a valuable guide to the views and perceptions of young people with respect to abstinence and faithfulness before interventions are implemented.

    Full Text Available Este artigo analisa o problema da produção do controle e da ordem em prisões brasileiras, utilizando as perspectivas histórica e sociológica, e levanta a hipóteses de que, no Brasil, convivem duas modalidades de construção da ordem e do controle nas prisões. Uma delas, minoritária, baseia-se na prerrogativa do Estado na gestão do dia a dia prisional. A outra é relativa à negociação da pacificação do presídio entre o Estado e as lideranças dos presos. Embora, no primeiro caso, a prerrogativa do Estado possa ser vinculada às condições institucionais adequadas e, no segundo (negociação entre o estado e as lideranças dos presos às condições precárias dos presídios, como superlotação, número reduzido de agentes penitenciários, entre outros, a análise apontou que ambas as modalidades traduzem formas de relacionamentos e interações sociais historicamente produzidas entre o Estado e a sociedade, que remetem à fundação da República, recriadas através do habitus dos atores sociais, não se restringindo exclusivamente ao espaço social das prisões.

    Adults experiencing homelessness and serious mental illnesses (SMI) are at an increased risk of poor mental health and treatment outcomes compared with stably housed adults with SMI. The additional issue of alcohol misuse further complicates the difficulties of those living with homelessness and SMI. In this secondary data analysis, the authors investigated the impact of homelessness on attrition and alcohol use in a contingency management (CM) intervention that rewarded alcohol abstinence in outpatients with SMI. The associations between housing status and attrition and alcohol abstinence during treatment, as assessed by ethyl glucuronide (EtG) urine tests, were evaluated in 79 adults diagnosed with alcohol dependence and SMI. Thirty-nine percent (n = 31) of participants reported being homeless at baseline. Individuals who were homeless were more likely to drop out of CM (n = 10, 62.5%) than those who were housed (n = 4, 16.7%), χ 2 (1) = 8.86, P < .05. Homelessness was not associated with attrition in the noncontingent control group. Accounting for treatment group and prerandomization EtG levels, neither the effect of housing status nor the interaction of housing status and group were associated with EtG-assessed alcohol abstinence during treatment. Individuals experiencing homelessness and co-occurring alcohol dependence and SMI receiving CM had higher rates of attrition, relative to those who were housed. Homelessness was not associated with differences in biologically assessed alcohol abstinence.

    Adolescence is a crucial time for initiation of tobacco-smoking. Developing more effective treatment interventions for tobacco-smoking in youth is therefore critical to reduce smoking rates in both adolescent and adult populations. Elucidation of the neural mechanisms of successful behavioral change (abstinence) will allow for improvement of therapies based on known brain mechanisms. Twenty-one adolescent tobacco-smokers (14-19 years) participated in functional magnetic resonance imaging (fMRI) during performance of a cognitive control (Stroop) task prior to randomization to smoking cessation treatment (trial of combined nicotine replacement therapy/placebo and contingency management for attendance/abstinence; NCT01145001). Fourteen adolescents also participated in fMRI scanning following completion of the six-week trial. fMRI data were analyzed using random-effects models in SPM12. Paired t-tests were used to identify group-level changes (main effect of treatment exposure) in neural functional responses. Regression models were used to identify individual-level changes associated with treatment-outcomes (percent days abstinent, maximum days of consecutive abstinence). Main effects of Stroop task performance (contrast of incongruent versus congruent trials) were seen across a priori ROIs at both pre- and post-treatment (pFWEoptimal treatment responses in this population.

    This study collected data on drug and alcohol workers' (n = 55) and clients' (n = 139) perspectives on what constitutes a "recovery" from substance use disorder. Data were collected during 2010 from four residential faith-based treatment programs across the east coast of Australia. Self-report surveys specifically designed for this study were administered. Responses were compared using nonparametric test. Abstinence was seen as an important component of recovery but nonabstinent factors were also seen as having an important role. Staff placed more emphasis on clients taking responsibility for their problems and on the role of spiritual development. The importance of nonabstinence components was positively associated with a person's time in treatment and recovery. Implications, limitations, and future directions are noted.

    2007-01-01

    For most young women and young men throughout the world, adolescence is a time for the discovery and expression of sexuality. The process of this essential human behavior often occurs without accurate information about normal development, physiological processes, and the potential physical, social, and psychological results of sexual exploration. Much of the insufficient information available to adolescents in the United States and elsewhere is not accidental, but can be directly attributed to U.S. government policies, some of which infringe upon the human and reproductive rights of adolescents. Established U.S. policy that promotes abstinence-only programming through selective funding is a violation of adolescent reproductive rights, both at home and abroad. The authors explore why receiving accurate and appropriate sex education is a basic human right for adolescents, and provide suggestions about effective ways to address violations of this right.

  5. Development of a validation test for self-reported abstinence from smokeless tobacco products: preliminary results

    1988-01-01

    Using X-ray fluorescence spectrometry, 11 heavy elements at concentrations that are easily detectable have been identified in smokeless tobacco products. These concentrations were found to increase in cheek epithelium samples of the user after exposure to smokeless tobacco. This feasibility study suggests that the level of strontium in the cheek epithelium could be a valid measure of recent smokeless tobacco use. It also demonstrates that strontium levels become undetectable within several days of smokeless tobacco cessation. This absence of strontium could validate a self-report of abstinence from smokeless tobacco. Finally, the X-ray spectrum of heavy metal content of cheek epithelium from smokeless tobacco users could itself provide a visual stimulus to further motivate the user to terminate the use of smokeless tobacco products

    2017-01-01

    Previous research has demonstrated that White college students are more likely to drink alcohol at a greater frequency and quantity compared to their African American counterparts. Examining race-related factors that structure alcohol use among college students remains an important area of research. In this study, we specifically examine perceived discrimination and its association with both heavy episodic drinking (HED) and alcohol abstinence among college students. Items that measured perceived racial discrimination in alcohol use contexts and demographic characteristics were used as independent and control variables. African American students were more likely to abstain from alcohol and less likely to engage in HED compared to their White counterparts. Results also suggest that students who believe their drinking will solicit race-based police bias have lower odds of engaging in HED and greater odds of alcohol abstention. We conclude that unsolicited policing, experienced by African Americans generally, and White Americans on campuses, explains effect sizes.

    Christian perfection, the evangelical doctrine that gave rise to abstinence as it is understood and practiced in America, originated in Britain with John Wesley and the Methodists. We examine why that doctrine floundered in its country of origin, opening the door to a more pluralistic and evidence-based approach to problems such as alcohol and drug abuse. Although social and political factors were important (the stratification of British society stood in the way of holding everyone to the same moral standard, and the drink trade was far better organized than its American counterpart), Britain's intellectual elite also played a vital role, heaping ridicule on the temperance movement and subjecting it to a devastating critique.

    Preclinical studies suggest that medications enhancing the brain gamma amino butyric acid (GABA) system attenuate the rewarding effects of stimulants including nicotine. These preclinical studies have not been followed up in systematic human studies. This study was conducted to examine the effects of a GABAergic medication, tiagabine, on acute physiological and subjective effects of intravenous (i.v.) nicotine and on tobacco withdrawal symptoms in overnight abstinent smokers. The proposed mechanism of action for tiagabine is selective inhibition of GABA transporter type I, which leads to increases in synaptic GABA levels. Eight male and four female smokers participated in a double-blind, placebo-controlled, crossover study. In each of three experimental sessions, participants were treated orally with a single 4- or 8-mg dose of tiagabine or placebo. Two hours following the medication treatment, participants received i.v. saline, followed 30 min later by 1.5 mg/70 kg i.v. nicotine. Tiagabine treatment did not affect the heart rate or blood pressure changes induced by nicotine. There was a significant treatment effect for the subjective responses to nicotine, such that tiagabine, compared to placebo, attenuated the ratings of "good effects" and "drug liking." Tiagabine treatment at 8 mg attenuated the craving for cigarettes and enhanced the cognitive performance in the Classical Stoop Tests, compared to placebo or 4 mg tiagabine condition. These results suggest that GABA enhancing medication tiagabine may reduce the rewarding effects of nicotine and improve cognitive performance in abstinent smokers. The utility of GABA medications for smoking cessation needs to be examined further in controlled clinical trials.

    Men and women differ in personality characteristics and may be motivated to use alcohol for different reasons. The goals of the present study were to characterize personality and drinking motives by gender and alcoholism status in adults, and to determine how alcoholism history and gender are related to the associations between personality traits and drinking motivation. Personality characteristics were assessed with the Eysenck Personality Questionnaire, which includes Extraversion, Neuroticism, Psychoticism and Lie (Social Conforming) scales. To evaluate drinking motivation, we asked abstinent long-term alcoholic men and women, and demographically similar nonalcoholic participants to complete the Drinking Motives Questionnaire, which includes Conformity, Coping, Social and Enhancement scales. Patterns of personality scale scores and drinking motives differed by alcoholism status, with alcoholics showing higher psychopathology and stronger motives for drinking compared with controls. Divergent gender-specific relationships between personality and drinking motives also were identified, which differed for alcoholics and controls. Alcoholic and control men and women differed with respect to the associations between personality traits and motives for drinking. A better understanding of how different personality traits affect drinking motivations for alcoholic men and women can inform individualized relapse prevention strategies. Men and women differed in their personality traits and their motivations for drinking, and these relationships differed for abstinent alcoholic and control groups. Additionally, alcoholics scored higher on Neuroticism and Psychoticism personality traits, and had lower Enhancement and Social Conformity drinking motives than nonalcoholic controls.

    This study compared the relative efficacy of two contingency management (CM) interventions versus standard care. During a 12-week intervention, opioid dependent participants (N = 120) were maintained on thrice-a-week (M, W, F) buprenorphine plus therapist and computer-based counseling. They were randomized to receive: (a) medication contingencies (MC= thrice weekly dosing schedule vs. daily attendance and single-day 50% dose reduction imposed upon submission of an opioid and/or cocaine positive urine sample); (b) voucher contingency (VC=escalating schedule for opioid and/or cocaine negative samples with reset for drug-positive samples); or (c) standard care (SC), with no programmed consequences for urinalysis results. Voucher reinforcement resulted in better 12-week retention (85%) compared to contingent medication (58%; p=0.009), but neither differed from standard care (76% retained). The groups submitted a similar overall percentage of opioid and cocaine-free urines (MC = 79%, VC = 76%, SC = 69%). After adjusting for baseline differences in employment, the medication contingency group achieved 1.5 more continuous weeks of combined opioid/cocaine abstinence than standard care (p=0.030), while the voucher group had 2 more total weeks of abstinence than standard care (p=0.048). Drug use results suggest that the two interventions were both efficacious, with effects seen primarily in opioid rather than cocaine test results. Findings should be interpreted in light of the greater attrition associated with medication-based contingencies versus the greater monetary costs of voucher-based contingencies. PMID:19653788

  11. Resting-State Neuroimaging and Neuropsychological Findings in Opioid Use Disorder during Abstinence: A Review.

    Dependence to opiates, including illicit heroin and prescription pain killers, and treatment of the opioid use disorder (OUD) have been longstanding problems over the world. Despite intense efforts to scientific investigation and public health care, treatment outcomes have not significantly improved for the past 50 years. One reason behind the continuing use of heroin worldwide despite such efforts is its highly addictive nature. Brain imaging studies over the past two decades have made significant contribution to the understanding of the addictive properties as to be due in part to biological processes, specifically those in the brain structure and function. Moreover, traditional clinical neuropsychology studies also contribute to the account in part for the treatment-refractory nature of the drug abuse. However, there is a gap between those studies, and the rates of relapse are still high. Thus, a multidisciplinary approach is needed to understand the fundamental neural mechanism of OUD. How does the brain of an OUD patient functionally and cognitively differ from others? This brief review is to compare and contrast the current literature on non-invasive resting state neuroimaging and clinical neuropsychological studies with the focus on the abstinence stage in OUD. The results show as follow: Brain connectivity strength in the reward system, dysregulation of circuits associated with emotion and stress, enhanced beta and alpha power activity, and high impulsivity are induced by OUD.Some recovery signs in cognition are demonstrated in OUD subjects after prolonged abstinence, but not in the subjects undergoing methadone treatment.Normalization in the composition of brain oscillations especially in the temporal region is induced and restored by methadone treatment in roughly 6 months in mean duration for OUDs having a mean opioid-use history of 10 years. We hope that the review provides valuable implications for clinical research and practice and paves a new insight

    (±)3,4-Methylenedioxymethamphetamine (MDMA) is a popular recreational drug that has potential to damage brain serotonin (5-HT) neurons in humans. Brain 5-HT neurons play a role in pain modulation, yet little is known about long-term effects of MDMA on pain function. Notably, MDMA users have been shown to have altered sleep, a phenomenon that can lead to altered pain modulation. This study sought to assess pain processing in MDMA users using objective methods, and explore potential relationships between pain processing and sleep indices. Forty-two abstinent MDMA users and 43 age-matched controls participated in a 5-day inpatient study. Outcome measures included standardized measures of pain, sleep polysomnograms, and power spectral measures of the sleep EEG. When differences in psychophysiological measures of pain were found, the relationship between pain and sleep measures was explored. MDMA users demonstrated lower pressure pain thresholds, increased cold pain ratings, increased pain ratings during testing of diffuse noxious inhibitory control, and decreased Stage 2 sleep. Numerous significant relationships between sleep and pain measures were identified, but differences in sleep between the two groups were not found to mediate altered pain perception in MDMA users. Abstinent MDMA users have altered pain perception and sleep architecture. Although pain and sleep outcomes were related, differences in sleep architecture in MDMA users did not mediate altered pain responses. It remains to be determined whether alterations in pain perception in MDMA users are secondary to neurotoxicity of 5-HT-mediated pain pathways or alterations in other brain processes that modulate pain perception.

    Alcohol and nicotine are often used together, and there is a high rate of co-occurrence between alcohol and nicotine addiction. Most animal models studying alcohol and nicotine interactions have utilized passive drug administration, which may not be relevant to human co-addiction. In addition, the interactions between alcohol and nicotine in female animals have been understudied, as most studies have used male animals. To address these issues, we developed models of alcohol and nicotine co-consumption in male and female mice that utilized voluntary, oral consumption of unsweetened alcohol, nicotine and water. We first examined drug consumption and preference in single-drug, sequential alcohol and nicotine consumption tests in male and female C57BL/6 and DBA/2J mice. We then tested chronic continuous and intermittent access alcohol and nicotine co-consumption procedures. We found that male and female C57BL/6 mice readily co-consumed unsweetened alcohol and nicotine. In our continuous co-consumption procedures, we found that varying the available nicotine concentration during an alcohol abstinence period affected compensatory nicotine consumption during alcohol abstinence, and affected rebound alcohol consumption when alcohol was re-introduced. Consumption of alcohol and nicotine in an intermittent co-consumption procedure produced higher alcohol consumption levels, but not nicotine consumption levels, compared with the continuous co-consumption procedures. Finally, we found that intermittent alcohol and nicotine co-consumption resulted in physical dependence. Our data show that these voluntary co-consumption procedures can be easily performed in mice and can be used to study behavioral interactions between alcohol and nicotine consumption, which may better model human alcohol and nicotine co-addiction.

    Using the extinction-reinstatement model of cocaine relapse, we and others have demonstrated that the antibiotic ceftriaxone attenuates cue- and cocaine-primed reinstatement of cocaine-seeking. Reinstatement is contingent on the release of glutamate in the nucleus accumbens core (NAc) and manipulations that reduce glutamate efflux or block post-synaptic glutamate receptors attenuate reinstatement. We have demonstrated that the mechanism of action by which ceftriaxone attenuates reinstatement involves increased NAc GLT-1 expression and a reduction in NAc glutamate efflux during reinstatement. Here we investigated the effects of ceftriaxone (100 and 200 mg/kg) on context-primed relapse following abstinence without extinction training and examined the effects of ceftriaxone on GluA1, GluA2 and GLT-1 expression. We conducted microdialysis during relapse to determine if an increase in NAc glutamate accompanies relapse after abstinence and whether ceftriaxone blunts glutamate efflux. We found that both doses of ceftriaxone attenuated relapse. While relapse was accompanied by an increase in NAc glutamate, ceftriaxone (200 mg/kg) was unable to significantly reduce NAc glutamate efflux during relapse despite its ability to upregulate GLT-1. GluA1 was reduced in the NAc by both doses of ceftriaxone while GluA2 expression was unchanged, indicating that ceftriaxone altered AMPA subunit composition following cocaine. Finally, GLT-1 was not altered in the PFC by ceftriaxone. These results indicate that it is possible to attenuate context-primed relapse to cocaine-seeking through modification of post-synaptic receptor properties without attenuating glutamate efflux during relapse. Furthermore, increasing NAc GLT-1 protein expression is not sufficient to attenuate glutamate efflux. Copyright © 2016 Elsevier B.V. and ECNP. All rights reserved.

    Extinction responding and cue-induced reinstatement of cocaine seeking after 60-days of forced abstinence are attenuated in male rats that self-administered cocaine during adolescence, compared with adults. Given that environmental enrichment during abstinence decreases reinstatement among adults, a possible explanation for attenuated reinstatement among adolescents is that standard pair-housing in prior studies creates a more stimulating environment for younger rats. Therefore, we tested whether standard pair-housing is necessary for the attenuated reinstatement among adolescents by determining whether an impoverished environment during abstinence would increase reinstatement among adolescents, up to adult levels. Conversely, we also tested whether environmental enrichment could further decrease reinstatement among adolescents, and whether we could replicate effects of environmental enrichment to decrease reinstatement among adults down to adolescent levels (positive controls). Adolescent and adult male Wistar rats self-administered cocaine intravenously for 12days (fixed ratio 1; 0.36mg/kg per infusion; 2h sessions). Rats were then moved into enriched (grouped, large cages, novel toys), standard (pair-housed, shoebox cages), or impoverished (isolated, hanging cages) housing conditions. After 60days, extinction and cue-induced reinstatement of cocaine seeking were tested, followed by drug-primed reinstatement (0, 5, 10mg/kg cocaine, i.p.). Consistent with previous results, extinction and cue-induced reinstatement were attenuated in adolescent-onset groups compared with adults; this age difference also extended to drug-primed reinstatement. In support of the present hypothesis, an impoverished environment during abstinence increased reinstatement among adolescents to levels that were not different from adult standard-housing levels. These data suggest that abstinence environment influences the enduring effects of cocaine among adolescents as well as adults

    Many with alcohol and other drug dependence have concurrent marijuana use, yet it is not clear how to address it during addiction treatment. This is partially due to the lack of clarity about whether marijuana use impacts one's ability to achieve abstinence from the target of addiction treatment. We examined the association between marijuana use and abstinence from other substances among individuals with substance dependence. A secondary analysis of the Addiction Health Evaluation And Disease management study, a randomized trial testing the effectiveness of chronic disease management. Individuals met criteria for drug or alcohol dependence and reported recent drug (i.e. opioid or stimulant) or heavy alcohol use. Recruitment occurred largely at an inpatient detoxification unit, and all participants were referred to primary medical care. The association between marijuana use and later abstinence from drug and heavy alcohol use was assessed using longitudinal multivariable models. Of 563 study participants, 98% completed at least one follow-up assessment and 535 (95%) had at least one pair of consecutive assessments and were included. In adjusted analyses, marijuana use was associated with a 27% reduction in the odds of abstinence from drug and heavy alcohol use (adjusted odds ratio 0.73 [95% CI, 0.56-0.97], P=0.03). Marijuana use among individuals with alcohol or other drug dependence is associated with a lower odds of achieving abstinence from drug and heavy alcohol use. These findings add evidence that suggests concomitant marijuana use among patients with addiction to other drugs merits attention from clinicians. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available Among strategies to prevent HIV, other sexually transmitted infections (STIs and unwanted pregnancies, are programs that promote sexual abstinence among adolescents. However, literature suggests that there may be differences in the understanding of abstinence across adolescents, and this study sought to explore the understanding of sexual abstinence among both male and female learners in a secondary school in a semi-rural area of North West Province, South Africa. Focus group discussions were used to collect data from learners who were in grades 8–10 at the time of the study. The findings are that the learners in this area understand sexual abstinence as the decision not to have sex, and this was associated with prevention of HIV, STIs and unwanted pregnancies, which ensures a better future. Barriers to sexual abstinence include peer pressure, myths and wrong perceptions about sex, influence of drugs and alcohol and the influence of television. Based on how it is delivered, school-based sex education was viewed as both an enabler and barrier to sexual abstinence. It is recommended that programs to promote sexual abstinence be strengthened and such programs be community-based.

    Childhood maltreatment is widely accepted as a risk factor for drug addiction from adolescence to adulthood. However, the influence of childhood maltreatment on drug treatment related variables, such as drug abstinence motivation and self-concept, as well as self-efficacy, remains unclear. This study aims at exploring whether self-concept mediates the relationship between childhood maltreatment and abstinence motivation, as well as self-efficacy, among drug addicts. This study involves 816 (550 males, 226 females, mean age=34.59, range=16-58 years) drug addicts from compulsory detoxification units. Participants completed questionnaires, including the childhood trauma questionnaire 28 - item short form (CTQ - SF), Tennessee self-concept scale (TSCS), general self-efficacy scale (GSES), and drug abstinence motivation questionnaire (DAMQ). The structural equation model (SEM) analysis, including total and specific forms of maltreatment scores, showed that childhood maltreatment was negatively associated with self-concept, self-efficacy, and abstinence motivation. Self-concept was positively associated with self-efficacy and abstinence motivation. Conversely, significant association between self-efficacy and abstinence motivation did not exist. An indirect analysis showed that self-concept mediated the relationship between childhood maltreatment and self-efficacy. Critically, self-concept arbitrated the relationship between childhood maltreatment and abstinence motivation. The indirect effect of self-concept between childhood maltreatment and abstinence motivation still existed when the total scores of maltreatment were replaced by the scores of specific forms of maltreatment. These results demonstrated that self-concept is a critical factor in understanding the relationship between childhood maltreatment and abstinence motivation, as well as self-efficacy, among drug addicts. Improving the sense of self-worth may be an effective intervention therapy among drug addicts

    For vasodilator stress, myocardial perfusion imaging (MPI) with at least 12-h caffeine abstinence is recommended, as it attenuates cardiovascular hyperemic response of adenosine and dipyridamole. However, many published conflicting results have shown no significant effect upon perfusion abnormalities in MPI performed without caffeine abstinence. The aim of this study was to compare the hemodynamic changes and negative predictive value (NPV) of normal MPIs with adenosine stress performed with or without caffeine abstinence. This was a prospective study that accrued 50 patients from May 2013 till September 2013 and followed till November 2014. These patients had a normal adenosine-gated MPI (GMPI) with technetium-99m methoxy isobutyl isonitrile ( 99m Tc-MIBI) after 12-h caffeine abstinence (no-caffeine). Next day, all patients had a repeat adenosine stress within 60 min after ingestion of a cup of coffee (about 80 mg of caffeine) followed by no MPI in 30 patients due to concern about radiation dose (prior-caffeine adenosine—no MPI; group A). Twenty patients opted for a repeat MPI (prior-caffeine adenosine—MPI; group B). Adenosine-induced hemodynamic response and NPV of the normal MPI with no-caffeine and prior-caffeine protocols were compared. The mean age of the study cohort was 57 ± 9 years with a male-to-female ratio of 76:24% and mean body mass index (BMI) of 26.915 ± 4.121 kg/m 2 . Prevalence of hypertension, diabetes, dyslipidemia, and positive family history were 76%, 20%, 22%, and 17%, respectively. Comparison of group A with group B revealed no significant difference in demographic parameters, hemodynamic or electrocardiography (ECG) parameters, or left ventricular (LV) function parameters during adenosine intervention with prior-caffeine and no-caffeine protocols. During the follow-up, no fatal myocardial infarction (MI) was reported but 6 nonfatal MIs were reported based upon the history of short hospitalization for chest pain but without biochemical

    Researchers often assess condom use only among participants who report recent sexual behaviour, excluding participants who report no recent vaginal sex or who did not answer questions about their sexual behaviour, but self-reported sexual behaviour may be inaccurate. This study uses a semen Y-chromosome biomarker to assess semen exposure among participants who reported sexual abstinence or did not report their sexual behaviour. This prospective cohort study uses data from 715 sexually active African-American female adolescents in Atlanta, surveyed at baseline, 6 months and 12 months. Participants completed a 40 min interview and were tested for semen Y-chromosome with PCR from a self-administered vaginal swab. We predicted Y-chromosome test results from self-reported sexual behaviour using within-subject panel regression. Among the participants who reported abstinence from vaginal sex in the past 14 days, 9.4% tested positive for semen Y-chromosome. Among item non-respondents, 6.3% tested positive for semen Y-chromosome. Women who reported abstinence and engaged in item non-response regarding their sexual behaviour had respectively 62% and 78% lower odds of testing positive for Y-chromosome (OR 0.38 (0.21 to 0.67), OR 0.22 (0.12 to 0.40)), controlling for smoking, survey wave and non-coital sexual behaviours reported during abstinence. Adolescents who report sexual abstinence under-report semen exposure. Research should validate self-reported sexual behaviour with biomarkers. Adolescents who engage in item non-response regarding vaginal sex test positive for semen Y-chromosome at similar rates, which supports the practice of grouping non-respondents with adolescents reporting abstinence in statistical analysis.

    Despite public debate about the content of sexuality education in schools, state and federal policy has increasingly financed and legislated abstinence-only education over the past decade. Although public schools strive to meet the needs of parents who, as taxpayers, fund the educational system, little is known about parental desires regarding sexuality education in states with mandated abstinence education. The objective of this study was to assess parental opinion about sexuality education in public schools in North Carolina, a state with mandated abstinence education. Computer-assisted, anonymous, cross-sectional telephone surveys were conducted among 1306 parents of North Carolina public school students in grades K-12. Parental support for sexuality education in public schools and 20 sexuality education topics was measured. We defined comprehensive sexuality education as education that includes a discussion of how to use and talk about contraception with partners. Parents in North Carolina overwhelmingly support sexuality education in public schools (91%). Of these respondents, the majority (89%) support comprehensive sexuality education. Less than a quarter of parents oppose teaching any specific topic, including those typically viewed as more controversial, such as discussions about sexual orientation, oral sex, and anal sex. Parents' level of education was inversely related to support for specific sexuality education topics and comprehensive education, although these differences were small in magnitude. More than 90% of respondents felt that parents and public health professionals should determine sexuality education content and opposed the involvement of politicians. Current state-mandated abstinence sexuality education does not match parental preference for comprehensive sexuality education in North Carolina public schools.

    2012-10-01

    Full Text Available Background: Dissociation is a defense mechanism by which people under stress detach their thoughts, emotions and behaviors from the normal stream of consciousness in order to protect themselves against the threats imposed on their ego. The phenomenon of dissociation is associated with a group of psychiatric disorders, including substance use disorders (SUDs, and leads individuals to incline towards drugs. This study examines the relationship between the dissociation symptoms prior to abstinence treatment and the abstinence success.Materials and Methods: 128 opioid dependent males were selected randomly and examined using Dissociative Experience Scale (DES questionnaire and a self-administered questionnaire. After two months, the subjects were divided, in terms of abstinence success, into three groups of rehabilitated (successfully-rehabilitated, recurrence, and non-referral groups. The three groups were compared to each other with regard to the DES mean score, demographic characteristics, drug use history, self-destruction, and self-mutilation history, using statistical methods of χ2, t-test, and one-way ANOVA.Results: The results showed that 39% of the subjects obtained a dissociation score of 15 and above in DES scale. There was a significant negative correlation between the dissociation score and abstinence success (p=0.001. There was no significant relationship between the DES score and demographic factors such as education level, residential location, and marital status. Moreover, the treatment follow-up of individuals showed that there was no significant relationship among the three groups in terms of age and education level.Conclusion: The extent of dissociative phenomena in drug dependent individuals who decide to discontinue drug abuse is effective in the sense of treatment outcome. Hence, the individuals are recommended to be examined for dissociative symptoms prior to drug treatment, and receive the proper treatment.

    Aims Contingency management (CM) uses tangible incentives to systematically reinforce abstinence and is among the most efficacious psychosocial substance abuse treatments. This study assessed the feasibility and initial efficacy of a portable CM procedure designed to address technical limitations for detecting drinking that have prevented using CM for alcohol problems. Design Participants received a cell phone, breathalyzer, and training on video-recording alcohol breath tests (BrACs) and texting results. For 4 weeks, staff texted participants 1–3 times daily indicating a BrAC was due within the hour. Participants were randomized to (1) modest compensation for submitting dated time-stamped BrAC videos regardless of results or (2) the same plus CM with escalating vouchers for on-time alcohol-negative tests (n-BrAC; .5). Percent of n-BrACs and LDA were greater with CM, and there was an interaction effect on drinking frequency and negative consequences, with decreases over time with CM (p=.00; effect sizes d=.52 to .62). Conclusion Cell phone technology may be useful for extending CM to treatment for alcohol problems. PMID:23279560

    The object of this study was the identification of brain areas that were significantly more connected than other regions with a previously identified reference region, the posterior cingulate cortex, during the presentation of visual cues in alcoholics. Alcohol-related and neutral video sequences were presented to 30 alcoholics who had been abstinent for at least 4 days. Participants underwent a psychometric assessment before and after the presentation of the video sequences. Functional MRI data were acquired. Psychophysiological interaction analyses were carried out. Participants reported a significant increase in craving and arousal after the presentation of alcohol-related video sequences. The simple contrast alcohol versus neutral was found not to be significantly different in the present study. The brain regions that were found to correlate significantly more with the posterior cingulate cortex under the alcohol-related condition were the inferior parietal lobe, the medial temporal lobe, the inferior frontal gyrus, the postcentral gyrus, and the precuneus. The involvement of these regions in processes of memory, self-control, and self-reflection with a particular focus on alcohol dependence and craving will be discussed. Copyright © 2013 S.

  16. Clonidine improved laboratory-measured decision-making performance in abstinent heroin addicts.

    Directory of Open Access Journals (Sweden)

    Xiao-Li Zhang

    Full Text Available BACKGROUND: Impulsivity refers to a wide spectrum of actions characterized by quick and nonplanned reactions to external and internal stimuli, without taking into account the possible negative consequences for the individual or others, and decision-making is one of the biologically dissociated impulsive behaviors. Changes in impulsivity may be associated with norepinephrine. Various populations of drug addicts all performed impulsive decision making, which is a key risk factor in drug dependence and relapse. The present study investigated the effects of clonidine, which decreased norepinephrine release through presynaptic alpha-2 receptor activation, on the impaired decision-making performance in abstinent heroin addicts. METHODOLOGY/PRINCIPAL FINDINGS: Decision-making performance was assessed using the original version of Iowa Gambling Task (IGT. Both heroin addicts and normal controls were randomly assigned to three groups receiving clonidine, 0, 75 µg or 150 µg orally under double blind conditions. Psychiatric symptoms, including anxiety, depression and impulsivity, were rated on standardized scales. Heroin addicts reported higher scores on the Barratt Impulsiveness Scale and exhibited impaired decision-making on the IGT. A single high-dose of clonidine improved the decision-making performance in heroin addicts. CONCLUSIONS/SIGNIFICANCE: Our results suggest clonidine may have a potential therapeutic role in heroin addicts by improving the impaired impulsive decision-making. The current findings have important implications for behavioral and pharmacological interventions targeting decision-making in heroin addiction.

    This secondary analysis of data from a randomized controlled trial tested two behavioral economics mechanisms (substitutability and delay discounting) to explain outcomes using contingency management (CM) for methamphetamine dependence. Frequency and purchase type (hedonic/utilitarian and consumable/durable) of CM payments were also examined. A total of 82 methamphetamine-dependent gay/bisexual men randomly assigned to conditions delivering CM received monetary vouchers in exchange for stimulant-negative urine samples in a 16-week trial requiring thrice weekly visits (Shoptaw et al., 2005). At any visit participants could redeem vouchers for goods. A time-lagged counting process Cox Proportional Hazards model for recurrent event survival analysis examined aspects of the frequency and type of these CM purchases. After controlling for severity of baseline methamphetamine use and accumulated CM wealth, as measured by cumulative successful earning days, participants who redeemed CM earnings at any visit ("spenders") were significantly more likely to produce stimulant-negative urine samples in the subsequent visit, compared with those who did not redeem ("savers") 1.011* [1.005, 1.017], Z = 3.43, p economic concept of substitutability of CM purchases and explain trial outcomes as a function of frequency of CM purchases rather than frequency or accumulated total CM earnings.

    Although there is evident association between alcohol-related hospitalization and alcohol use, the relationship has not been well examined. This study analyzed the extent of alcohol abstinence, non-hazardous use and hazardous use among people who had experienced alcohol-related hospitalization during the preceding decade. Registry data concerning alcohol-related hospitalizations between 1996 and 2007 were linked to two representative surveys, in 2006 and 2007, of residents of Stockholm County. Relevant contrasts were modeled, using logistic regression, in the pooled sample (n = 54 955). Ages were 23-84 years at follow-up. Among persons previously hospitalized (n = 576), half reported non-hazardous use. Non-hazardous use was less prevalent than in the general population--and the extent of non-hazardous use did not change over time following hospitalization. There were no significant age differences, but non-hazardous use was less frequent among people with repeated episodes of care. One in six was abstinent. Abstinence was more common among the old, while hazardous use (exceeding 14 drinks per week for men, and 9 drinks per week for women) decreased with age. Abstinence also increased over time; among persons hospitalized ten years ago, the abstinence rate was twice that of the general population. Associations with hazardous use over time were less conclusive. Hazardous use among those previously hospitalized decreased over time in one sample but not in the other. After pooling the data, there were indications of a decrease over time following hospitalization, but more prevalent hazardous use than in the general population. Following alcohol-related hospitalization, abstinence increased, and there was no evidence of regression towards the mean, i.e., towards non-hazardous use. Abstinence was also more widespread among previously hospitalized persons of older ages. With advancing age, changing hazardous alcohol habits among previously hospitalized appears to yield a

    This is the first quantitative analysis of data from urine drug tests for compliance to treatment medications and abstinence from drug abuse across "levels of care" in six eastern states of America. Comprehensive Analysis of Reported Drugs (CARD) data was used in this post-hoc retrospective observational study from 10,570 patients, filtered to include a total of 2,919 patients prescribed at least one treatment medication during 2010 and 2011. The first and last urine samples (5,838 specimens) were analyzed; compliance to treatment medications and abstinence from drugs of abuse supported treatment effectiveness for many. Compared to non-compliant patients, compliant patients were marginally less likely to abuse opioids, cannabinoids, and ethanol during treatment although more likely to abuse benzodiazepines. Almost 17% of the non-abstinent patients used benzodiazepines, 15% used opiates, and 10% used cocaine during treatment. Compliance was significantly higher in residential than in the non-residential treatment facilities. Independent of level of care, 67.2% of the patients (n = 1963; Pabuse detected in either the first or last urine samples (abstinence). Moreover, in 2010, 16.9% of the patients (n = 57) were abstinent at first but not at last urine (deteriorating abstinence), the percentage dropped to 13.3% (n = 174) in 2011; this improvement over years was statistically significant. A longitudinal analysis for abstinence and compliance was studied in a randomized subset from 2011, (n = 511) representing 17.5% of the total cohort. A statistically significant upward trend (p = 2.353×10-8) of abstinence rates as well as a similar but stronger trend for compliance ((p = 2.200×10-16) was found. Being cognizant of the trend toward drug urine testing being linked to medical necessity eliminating abusive screening, the interpretation of these valuable results require further intensive investigation.

    The United States ranks first among developed nations in rates of both teenage pregnancy and sexually transmitted diseases. In an effort to reduce these rates, the U.S. government has funded abstinence-only sex education programs for more than a decade. However, a public controversy remains over whether this investment has been successful and whether these programs should be continued. Using the most recent national data (2005) from all U.S. states with information on sex education laws or policies (N = 48), we show that increasing emphasis on abstinence education is positively correlated with teenage pregnancy and birth rates. This trend remains significant after accounting for socioeconomic status, teen educational attainment, ethnic composition of the teen population, and availability of Medicaid waivers for family planning services in each state. These data show clearly that abstinence-only education as a state policy is ineffective in preventing teenage pregnancy and may actually be contributing to the high teenage pregnancy rates in the U.S. In alignment with the new evidence-based Teen Pregnancy Prevention Initiative and the Precaution Adoption Process Model advocated by the National Institutes of Health, we propose the integration of comprehensive sex and STD education into the biology curriculum in middle and high school science classes and a parallel social studies curriculum that addresses risk-aversion behaviors and planning for the future.

    Binge eating disorder (BED) is strongly associated with obesity and related medical and psychiatric morbidities. Cognitive behavioral therapy (CBT) has consistently been shown to reduce binge eating frequency and improve psychological functioning, as well as to produce abstinence rates of roughly 50%. This study examined the relationship between binge abstinence and dietary and psychological outcomes after CBT for BED. Fifty adult patients with BED received 6-month treatments using a combination of CBT and dietary counseling. Trained interviewers conducted two 24-hour dietary recall interviews on randomly selected days at baseline and at 6 months. Participants had significant reductions in energy, macronutrient, and sugar intake and an increase in fruit intake. They reported significant reductions in BMI and binge eating frequency (from mean = 14.24 to mean = 1.90 binge eating episodes during the previous 28 days), as well as improvements in psychological functioning. Those who became binge abstinent reported eating roughly 400 fewer calories per day and experienced greater improvements in psychological functioning than those who did not. Findings from this study suggest that individuals who achieve complete cessation from binge eating have significantly improved dietary and psychological outcomes that could potentially improve weight status, compared with those who continue to binge eat post-treatment. © 2016 The Obesity Society.

    Full Text Available Background: Glutathione S Transferase (GST has been involved in detoxification process in the liver and its activity has been shown to be increased in alcohol abusers. In the current work we measured the GST activity, total thiol status, AST, ALT, and direct bilirubin in chronic alcohol abusers before and 30 days after alcohol abstinence and lifestyle modification. Methods: Serum and urine GST activity and total thiol status were determined using spectrophotometric methods and serum transaminases were determined using clinical chemistry analyzer. Results: We found,significant increase in serum and urine GST (p<0.001, AST (p<0.001, ALT (p<0.001, and decrease in total thiol status (p<0.001 in chronic alcohol abusers. GST activity significantly decreased (p<0.001 and total thiol status were improved significantly (p<0.001 30 days after alcohol abstinence and lifestyle modification. Conclusion: This study provides preliminary data to suggest the role of GST as prognostic indicator of alcohol abstinence with possible trend towards an improvement in liver function.

    This study documented the treatment cascade for engagement in care and abstinence at treatment exit as well as examined correlates of these outcomes for the first certified Matrix Model® substance abuse treatment site in Sub-Saharan Africa. This retrospective chart review conducted at a resource-limited community clinic in Cape Town, South Africa, assessed treatment readiness and substance use severity at treatment entry as correlates of the number of sessions attended and biologically confirmed abstinence at treatment exit among 986 clients who initiated treatment from 2009-2014. Sociodemographic and clinical correlates of treatment outcomes were examined using logistic regression, modeling treatment completion and abstinence at treatment exit separately. Of the 2,233 clients who completed screening, approximately 44% (n = 986) initiated treatment. Among those who initiated treatment, 45% completed at least four group sessions, 30% completed early recovery skills training (i.e., at least eight group sessions), and 13% completed the full 16-week program. Approximately half (54%) of clients who provided a urine sample had negative urine toxicology results for any substance at treatment exit. Higher motivation at treatment entry was independently associated with greater odds of treatment completion and negative urine toxicology results at treatment exit. Findings provide initial support for the successful implementation the Matrix Model in a resource-limited setting. Motivational enhancement interventions could support treatment initiation, promote sustained engagement in treatment, and achieve better treatment outcomes.

    Objective. Neuro-electrophysiological tools have been widely used in heroin addiction studies. Previous studies indicated that chronic heroin abuse would result in abnormal functional organization of the brain, while few heroin addiction studies have applied the effective connectivity tool to analyze the brain functional system (BFS) alterations induced by heroin abuse. The present study aims to identify the abnormality of resting-state heroin abstinent BFS using source decomposition and effective connectivity tools. Approach. The resting-state electroencephalograph (EEG) signals were acquired from 15 male heroin abstinent (HA) subjects and 14 male non-addicted (NA) controls. Multivariate autoregressive models combined independent component analysis (MVARICA) was applied for blind source decomposition. Generalized partial directed coherence (GPDC) was applied for effective brain connectivity analysis. Effective brain networks of both HA and NA groups were constructed. The two groups of effective cortical networks were compared by the bootstrap method. Abnormal causal interactions between decomposed source regions were estimated in the 1-45 Hz frequency domain. Main results. This work suggested: (a) there were clear effective network alterations in heroin abstinent subject groups; (b) the parietal region was a dominant hub of the abnormally weaker causal pathways, and the left occipital region was a dominant hub of the abnormally stronger causal pathways. Significance. These findings provide direct evidence that chronic heroin abuse induces brain functional abnormalities. The potential value of combining effective connectivity analysis and brain source decomposition methods in exploring brain alterations of heroin addicts is also implied.

    Background Peripheral immune system cytokines may play an integral role in underlying sensitized stress response and alcohol craving during early withdrawal. To date, the nature of these immune changes during early abstinence have not been examined. Methods Thirty-nine early abstinent, treatment-seeking alcohol dependent individuals and 46 socially drinking controls were exposed to three guided imageries: stress, alcohol cue and neutral. These were presented randomly across consecutive days. Plasma measures of tumor necrosis factor alpha (TNFα), tumor necrosis factor receptor 1 (TNFR1), interleukin-6 (IL-6), and interleukin-10 (IL-10), were collected at baseline, immediately after imagery and at various recovery time-points. Ratings of alcohol craving, negative mood and anxiety were also obtained at the same time-points. Results The alcohol group demonstrated decreased basal IL-10 compared with controls particularly following exposure to alcohol cue. They also showed a dampened TNFα and TNFR1 response to stress and cue, respectively, and a generalized suppression of IL-6. In the alcohol group, these immune system adaptations occurred alongside significant elevations in anxiety, negative mood and alcohol craving. Conclusions Findings demonstrate that broad immuno-suppression is still observed in alcohol dependent individuals after three weeks of abstinence and may be linked to motivation for alcohol.

    Addiction is a chronic brain disorder that progressively invades all aspects of personal life. Accordingly, addiction to opiates severely impairs interpersonal relationships, and the resulting social isolation strongly contributes to the severity and chronicity of the disease. Uncovering new therapeutic strategies that address this aspect of addiction is therefore of great clinical relevance. We recently established a mouse model of heroin addiction in which, following chronic heroin exposure, 'abstinent' mice progressively develop a strong and long-lasting social avoidance phenotype. Here, we explored and compared the efficacy of two pharmacological interventions in this mouse model. Because clinical studies indicate some efficacy of antidepressants on emotional dysfunction associated with addiction, we first used a chronic 4-week treatment with the serotonergic antidepressant fluoxetine, as a reference. In addition, considering prodepressant effects recently associated with kappa opioid receptor signaling, we also investigated the kappa opioid receptor antagonist norbinaltorphimine (norBNI). Finally, we assessed whether fluoxetine and norBNI could reverse abstinence-induced social avoidance after it has established. Altogether, our results show that two interspaced norBNI administrations are sufficient both to prevent and to reverse social impairment in heroin abstinent animals. Therefore, kappa opioid receptor antagonism may represent a useful approach to alleviate social dysfunction in addicted individuals. © 2016 Society for the Study of Addiction.

    The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration in the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability (SSI), Human Systems Integration (HSI), and Communications (Comm), and Certification to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Detect and Avoid (DAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project is conducting a series of human-in-the-loop (HITL) and flight test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity, and

    Full Text Available Phencyclidine (PCP induces a behavioural syndrome in rodents that bears remarkable similarities to some of the core symptoms observed in schizophrenic patients, among those cognitive deficits. The successful alleviation of cognitive impairments associated with schizophrenia (CIAS has become a major focus of research efforts as they remain largely untreated. The aim of the present study was to investigate the effects of selected antipsychotic and cognition enhancing drugs, namely haloperidol, risperidone, donepezil, and modafinil in an animal model widely used in preclinical schizophrenia research. To this end, the novel object recognition (NOR task was applied to rats abstinent following sub-chronic treatment with PCP. Rats were administered either PCP (5 mg/kg, i.p. or vehicle twice a day for 7 days, followed by a 7-day washout period, before testing in NOR. Upon testing, vehicle-treated rats successfully discriminated between novel and familiar objects, an effect abolished in rats that had previously been exposed to PCP-treatment. Acute treatment with modafinil (64 mg/kg, p.o. ameliorated the PCP-induced deficit in novel object exploration, whereas haloperidol (0.1 mg/kg, s.c., risperidone (0.2 mg/kg, i.p. and donepezil (3 mg/kg, p.o. were without significant effect. Given the negligible efficacy of haloperidol and risperidone, and the contradictory data with donepezil to treat CIAS in the clinic, together with the promising preliminary pro-cognitive effects of modafinil in certain subsets of schizophrenic patients, the sub-chronic PCP-NOR abstinence paradigm may represent an attractive option for the identification of potential novel treatments for CIAS.

    In many human alcoholics, abstinence is self-imposed because of the negative consequences of excessive alcohol use, and relapse is often triggered by exposure to environmental contexts associated with prior alcohol drinking. We recently developed a rat model of this human condition in which we train alcohol-preferring P rats to self-administer alcohol in one context (A), punish the alcohol-reinforced responding in a different context (B), and then test for relapse to alcohol seeking in Contexts A and B without alcohol or shock. Here, we studied the role of projections to nucleus accumbens (NAc) shell from ventral subiculum (vSub), basolateral amygdala, paraventricular thalamus, and ventral medial prefrontal cortex in context-induced relapse after punishment-imposed abstinence. First, we measured double-labeling of the neuronal activity marker Fos with the retrograde tracer cholera toxin subunit B (injected in NAc shell) and demonstrated that context-induced relapse is associated with selective activation of the vSub→NAc shell projection. Next, we reversibly inactivated the vSub with GABA receptor agonists (muscimol+baclofen) before the context-induced relapse tests and provided evidence for a causal role of vSub in this relapse. Finally, we used a dual-virus approach to restrict expression of the inhibitory κ opioid-receptor based DREADD (KORD) in vSub→NAc shell projection neurons. We found that systemic injections of the KORD agonist salvinorin B, which selectively inhibits KORD-expressing neurons, decreased context-induced relapse to alcohol seeking. Our results demonstrate a critical role of vSub in context-induced relapse after punishment-imposed abstinence and further suggest a role of the vSub→NAc projection in this relapse. In many human alcoholics, abstinence is self-imposed because of the negative consequences of excessive use, and relapse is often triggered by exposure to environmental contexts associated with prior alcohol use.

    Full Text Available Background: Today in the world and in Serbia is growing number of people who are addicted to benzodiazepine. A particular problem is the process of detoxification and treatment of benzodiazepine withdrawal syndrome due to a recurrence of symptoms of anxiety disorder, availability of benzodiazepines, falling motivation. Standard procedures have often proved unsuccessful and the last decade, and the search for new protocols, including the flumazenil, benzodiazepine receptor antagonist, is actualized. Case report: The patient aged 48 years was admitted to the specialist psychiatric clinic, for treatment of benzodiazepine addiction. Anxiety disorder was diagnosed since adolescence perennial addiction on benzodiazepines and the initial withdrawal syndrome. Former motivated topical treatments for detoxification were unsuccessful. The presence of dual diagnosis, persistence of both disorders in perennial cycle, treatment resistance and actual motivation contributed to the decision to opt rapid detoxification from benzodiazepines by flumazenil application protocol, for hospital treatment by adjuvant therapy with lamotrigine. After discharge from hospital in stable condition it was with no signs of withdrawal syndrome and a rebound of anxiety symptoms. Lamotrigine medication continued including CBT, held during the one-year abstinence monitoring, with sufficient social functionality. Discussion: The efficacy and safety of flumazenil in the treatment of benzodiazepine withdrawal syndrome was investigated in numerous clinical trials, and the mechanism of action is complex, from the benzodiazepine antagonist to inverse agonist in certain circumstances, as well as 'up-regulation' receptors, which together leads to a reduction in symptoms of abstinence syndrome and anxiety in the longer term after treatment, thereby acting favorably to the adherence and remission. Conclusions: Flumazenil protocol is an efficient method in the treatment of the benzodiazepine

    Full Text Available Abstract Background Young people are becoming increasingly exposed to the risk of HIV infection. According to the 2008 HIV/Syphilis sentinel survey in Nigeria, 3.3% of young people aged 15-19 years are infected. Primary prevention especially abstinence, remains one of the most realistic interventions for reducing further spread of the virus. However, the adoption of sexual abstinence as a prevention strategy among adolescents remains low and factors influencing its practice among urban young people in Nigeria are relatively unknown. The aim of the study was to document the sexual abstinence behaviour of in-school adolescents, the factors influencing or obstructing abstinence, and knowledge of HIV and AIDS in Ibadan, South-West Nigeria. Methods The study was a descriptive cross-sectional survey of students in Ibadan South-West Local Government Area. A total of 420 respondents (52% males and 48% females, selected through a multistage sampling technique, completed a semi-structured questionnaire. This was supplemented with eight focus group discussions (FGDs which had an average of 9 respondents within the 10 and 19 years age group. The data from the FGDs were transcribed and summarized manually while the quantitative data was analyzed using the Statistical Package for the Social Sciences to generate frequencies, cross tabulations of variables and logistic regression analysis. Results Twelve percent of the entire sample had ever had sex. Overall, knowledge of HIV transmission and prevention was high and most respondents favoured the promotion of abstinence as an HIV prevention strategy. A smaller proportion of male respondents (79% abstained compared with the females (98%. Major predictors of sexual abstinence were being a female, not having a boyfriend or girl friend, not using alcohol and having a positive attitude towards abstinence (P Sexual abstinence was also significantly associated with perceived self efficacy to refuse sex and negative

    (138 men, with acute coronary syndrome (ACS, in the city of Niteroi, state of Rio de Janeiro, Brazil, who underwent coronary angiography and genotype determination for the APOE *2*3*4 polymorphism by the Restriction Fragment Length Polymorphism (RFLP method. RESULTS: The frequency of the alleles was APOE *2 - 6.8%, *3 - 82.5%, *4 - 10.7%. Regarding the number of affected vessels, 27% of patients presented monoarterial obstruction, 33.8% biarterial and 39.1% triarterial and/or left coronary trunk. The degree of multivascular lesion did not correlate with the presence of the *4 allele (p= 0.78, but with age > 55 years (p=0.025, being an ex-smoker (p=0.004 and dyslipidemia (p=0.05 at the multivariate analysis and also with previous coronary artery disease (CAD (p=0.05, diabetes (p=0.038 and metabolic syndrome (p=0.021 at the univariate analysis. The prevalence of dyslipidemia, diabetes and systemic arterial hypertension (SAH was elevated regarding similar studies, with progressive increases in the prevalence of SAH (p=0.59 and diabetes (p=0.06, according to the number of affected vessels. CONCLUSION: The APOE polymorphism was not associated with the number of coronary vessels with significant obstruction at any age range. On the other hand, age > 55 years, being an ex-smoker and dyslipidemia associated with the multivascular lesion.

    Communal coping-a process in which romantic partners view a problem as ours rather than yours or mine, and take collaborative action to address it -has emerged as an important predictor of health and treatment outcomes. In a study of partners' pronoun use prior to and during couple-focused alcohol interventions, we examined first-person plural (we-talk) and singular (I-talk) pronouns as linguistic markers of communal coping and behavioral predictors of treatment outcome. Thirty-three couples in which one partner abused alcohol were selected from a randomized control trial (N = 63) of couple-focused Cognitive-Behavioral or Family Systems Therapy if they had unambiguously successful or unsuccessful treatment outcomes (i.e., patient maintained abstinence for 30 days prior to treatment termination or had more than one heavy drinking day in the same period). Pronoun measures for each partner were obtained via computerized text analysis from transcripts of partners' speech, derived from a videotaped pretreatment interaction task and three subsequent therapy sessions. Spouse we-talk during the intervention (accounting for pretreatment we-talk), as an index of communal orientation, uniquely predicted successful treatment outcomes. In contrast, both patient and spouse I-talk during the intervention (accounting for pretreatment I-talk), as a marker of individualistic orientation, uniquely predicted unsuccessful outcomes, especially when distinguishing active and passive (I vs. me/my) pronoun forms. Results strengthen evidence for the prognostic significance of spouse behavior for patient health outcomes and for communal coping (indexed via pronoun use) as a potential mechanism of change in couple-focused interventions for health problems. © 2015 Family Process Institute.

    Oral fluid (OF) is an accepted alternative biological matrix for drug treatment, workplace, and DUID (driving under the influence of drugs) investigations, but establishing the cannabinoid OF detection window and concentration cutoff criteria are important. Cannabinoid concentrations were quantified in OF from chronic, daily cannabis smokers during monitored abstinence. Δ(9)-tetrahydrocannabinol (THC)(3), cannabidiol (CBD), cannabinol (CBN), and 11-nor-9-carboxy-THC (THCCOOH) were determined in daily OF samples collected with the Quantisal™ device. GC-MS limits of quantification (LOQ) were 0.5 μg/L for THC and CBD, 1 μg/L for CBN, and 7.5 ng/L for THCCOOH. After providing written informed consent for this institutional review board-approved study, 28 participants resided from 4 to 33 days on the secure research unit and provided 577 OF specimens. At the LOQ, THC was generally quantifiable for 48 h, whereas CBD and CBN were detected only at admission. Median THCCOOH detection time was 13 days (CI 6.4-19.6 days). Mean THC detection rates decreased from 89.3% at admission to 17.9% after 48 h, whereas THCCOOH gradually decreased from 89.3% to 64.3% within 4 days. Criteria of THC ≥2 μg/L and THCCOOH ≥20 ng/L reduced detection to THC ratio ≤4 ng/μg or presence of CBD or CBN may indicate more recent smoking. THC, THCCOOH, CBD, and CBN quantification in confirmatory OF cannabinoid testing is recommended. Inclusion of multiple cannabinoid cutoffs accounted for residual cannabinoid excretion in OF from chronic, daily cannabis smokers and could reduce the potential for positive test results from passive cannabis smoke exposure and lead to greatly improved test interpretation.

    Full Text Available Abnormal decision making is a behavioral characteristic of drug addiction. Indeed, drug addicts prefer immediate rewards at the expense of future interests. Assessing the neurocognitive basis of decision-making related to drug dependence, combining event-related potential (ERP analysis and source localization techniques, may provide new insights into understanding decision-making deficits in drug addicts and further guide withdrawal treatment. In this study, EEG was performed in 20 abstinent heroin addicts (AHAs and 20 age-, education- and gender-matched healthy controls (HCs while they participated in a simple two-choice gambling task (99 vs. 9. Our behavioral results showed that AHAs tend to select higher-risk choices compared with HCs (i.e., more “99” choices than “9”. ERP results showed that right hemisphere preponderance of stimulus-preceding negativity was disrupted in AHAs, but not in HCs. Feedback-related negativity of difference wave was higher in AHAs than HCs, with the P300 amplitude associated with risk magnitude and valence. Using source localization that allows identification of abnormal brain activity in consequential cognitive stages, including the reward expectation and outcome evaluation stages, we found abnormalities in both behavioral and neural responses on gambling in AHAs. Taken together, our findings suggest AHAs have risk-prone tendency and dysfunction in adaptive decision making, since they continue to choose risky options even after accruing considerable negative scores, and fail to shift to a safer strategy to avoid risk. Such abnormal decision-making bias to risk and immediate reward seeking may be accompanied by abnormal reward expectation and evaluation in AHAs, which explains their high risk-seeking and impulsivity.

    To measure the variation in Brain-Derived Neurotrophic Factor (BDNF), Thiobarbituric Acid Reactive Substances (TBARS) and interleukin (IL) levels in crack-cocaine dependent adolescents after 21days of abstinence, comparing to levels found in a group of healthy controls. Cross-sectional nested on a short follow-up study. Two inpatient treatment units for adolescents, and a low-income neighborhood. 90 adolescents, of both genders, with diagnosis of crack cocaine dependence, and 81 healthy adolescents. Serum levels of IL-6, IL-10, TBARS and BDNF were assessed on admission and discharge. Drug addiction severity was assessed by the Addiction Severity Index - Teen Version (T-ASI) and Cocaine Craving Questionnaire - Brief version (CCQ-b). Psychiatric comorbidities were assessed by the Schedule for Affective Disorders and Schizophrenia for School-Age Children - Present and Lifetime Version (K-SADS-PL). Generalized Estimating Equations (GEE) were used to estimate the IL-6, IL-10, TBARS and BDNF levels, adjusted for confounders. Hedges' g was used to estimate effect size. TBARS (p=0.005, d=0.04), IL-6 (p=0.027, d=0.40) and IL-10 (p=0.025, d=0.41) were elevated and BDNF (p<0.001, d=0.62) was reduced (p<0.001), in patients, in comparison to controls, at admission time. Variation in those levels between admission and discharge were not significant. Crack-cocaine use seems to be associated with inflammatory and oxidative imbalances in adolescents.

    to evaluate differences in terms of smokers' attendance to National Health System (NHS) Stop-Smoking Services with a prevalent individual approach (SSSi), and to those with a prevalent group approach (SSSg). To identify predictive characteristics of success, in terms of quit rates at the end of treatment (QR0) and after 6 months (QR1), according to SSS type (SSSi/SSSg), treatment (individual/ group counseling with/without pharmacologic treatments), 5 SSS scores: type of structure (S), number and hours per week of SSS health professionals (P), SSS involvement in local tobacco control networks (N), and type of smokers' assessment (A); and 3 principal components of SSS characteristics. survey to 19 SSSs, and survey to smokers attending these SSSs, with a six month follow-up. 1,276 smokers attending 19 SSSs (664 at 7 SSSi; 612 at 12 SSSg) in 9 months in the period 2008-2010. smokers' attendance to scheduled sessions; QR0; QR1. even though SSSi treated more smokers per month (12 vs. 8 in SSSg), SSSi scheduled fewer treatment sessions (7 vs. 9 sessions) in a wider treatment period (3 months vs. 2 in SSSg). SSSg recorded lower P and higher A scores. Four out of 5 smokers attending SSSg and 2/5 of smokers attending SSSi completed treatment protocols. Considering all smokers, QR1 in both types of SSS were around 36%. Smokers treated with pharmacotherapy, those more motivated and with high self-efficacy, and those non-living together with smokers were more likely to recorded higher QR1. the most relevant interventions in order to increase the number of smokers treated at SSS and to improve cessation rates among them were: for SSSi, increasing completion to treatment protocol; for SSSg, improving the P scores to increase the number of treated smokers; for all SSS, increasing the use of pharmacotherapy in combination with individual/group counseling to sustain abstinence.

    Long-term cannabis use may confer cognitive deficits and increased risk of psychosis. However, the relationship between cannabis use and schizophrenia is complex. In particular, little is known about the effects of chronic cannabis use on the attention-related electric brain response in schizophrenia. We investigated auditory novelty and oddball P300 evoked potentials in a mixed sample of first-episode and chronic schizophrenic patients and healthy controls with (SZCA, n = 20; COCA, n = 20, abstinence ≥28 days) or without (SZ, n = 20; CO, n = 20) chronic cannabis use. Duration of regular cannabis use was 8.3 ± 5.6 (SZCA) and 9.1 ± 7.1 (COCA) years. In general, schizophrenic patients showed reduced P300 amplitudes. Cannabis use was associated with both a reduced early and late left-hemispheric novelty P300. There was a significant 'diagnosis × cannabis' interaction for the left-hemispheric late novelty P300 in that cannabis use was associated with a reduced amplitude in the otherwise healthy but not in the schizophrenic group compared with their relative control groups (corrected p  0.9, respectively). The left-hemispheric late novelty P300 in the otherwise healthy cannabis group correlated inversely with amount and duration of cannabis use (r = -0.50, p = 0.024; r = -0.57, p = 0.009, respectively). Our study confirms attentional deficits with chronic cannabis use. However, cannabis use may lead to different cognitive sequelae in patients with schizophrenia and in healthy controls, possibly reflecting preexisting alterations in the endocannabinoid system in schizophrenia.

    Full Text Available Recent work suggests that faulty co-activation or synchrony of multiple brain regions comprising “networks,” or an imbalance between opposing brain networks, is important in alcoholism. Previous studies showed higher fMRI resting state synchrony (RSS within the executive control (inhibitory control and emotion regulation networks and lower RSS within the appetitive drive network in long-term (multi-year abstinent alcoholics (LTAA vs. non substance abusing controls (NSAC. Our goal was to identify EEG networks that are correlated with the appetitive drive and executive function networks identified with fMRI in our previous alcohol studies. We used parallel ICA for multimodal data fusion for the 20 LTAA and 21 NSAC that had both usable fMRI and 64-channel EEG data. Our major result was that parallel ICA identified a pair of components that significantly separated NSAC from LTAA and were correlated with each other. Examination of the resting-state fMRI seed-correlation map component showed higher bilateral nucleus accumbens seed-correlation in the dorsolateral prefrontal cortex bilaterally and lower seed-correlation in the thalamus. This single component thus encompassed both the executive control and appetitive drive networks, consistent with our previous work. The correlated EEG coherence component showed mostly higher theta and alpha coherence in LTAA compared to NSAC, and lower gamma coherence in LTAA compared to NSAC. The EEG theta and alpha coherence results suggest enhanced top-down control in LTAA and the gamma coherence results suggest impaired appetitive drive in LTAA. Our results support the notion that fMRI RSS is reflected in spontaneous EEG, even when the EEG and fMRI are not obtained simultaneously.

    In humans, places or contexts previously associated with alcohol use often provoke relapse during abstinence. This phenomenon is modeled in laboratory animals using the ABA renewal procedure, in which extinction training in context (B) suppresses alcohol seeking, and renewal of this seeking occurs when the animal returns to the original training context (A). However, extinction training does not adequately capture the motivation for abstinence in human alcoholics who typically self-initiate abstinence in response to the negative consequences of excessive use. We recently developed a procedure to study renewal in laboratory rats after abstinence imposed by negative consequences (footshock punishment). The mechanisms of renewal of punished alcohol seeking are largely unknown. Here, we used the D1-family receptor antagonist SCH 23390 to examine the role of nucleus accumbens (NAc) shell and core dopamine in renewal of alcohol seeking after punishment-imposed abstinence. We trained alcohol-preferring "P rats" to self-administer 20% alcohol in Context A and subsequently suppressed alcohol taking via response-contingent footshock punishment in Context B. We tested the effects of systemic, NAc shell, or NAc core injections of SCH 23390 on renewal of alcohol seeking after punishment-imposed abstinence. We found that both systemic and NAc shell and core injections of SCH 23390 decreased renewal of punished alcohol seeking. Our results demonstrate a critical role of NAc dopamine in renewal of alcohol seeking after punishment-imposed abstinence. We discuss these results in reference to the brain mechanisms of renewal of alcohol seeking after extinction versus punishment. (c) 2015 APA, all rights reserved).

    Rationale Individuals with attention deficit hyperactivity disorder (ADHD) have a more difficult time quitting smoking compared to their non-ADHD peers. Little is known about the underlying behavioral mechanisms associated with this increased risk. Objectives This study aims to assess the effects of 24-h smoking abstinence in adult smokers with and without ADHD on the following outcomes: smoking-reinforced responding, withdrawal, and cognitive function. Methods Thirty-three (n=16 with ADHD, 17 without ADHD) adult smokers (more than or equal to ten cigarettes/day) were enrolled. Each participant completed two experimental sessions: one following smoking as usual and one following biochemically verified 24-h smoking abstinence. Smoking-reinforced responding measured via a progressive ratio task, smoking withdrawal measured via questionnaire, and cognition measured via a continuous performance test (CPT) were assessed at each session. Results Smoking abstinence robustly increased responding for cigarette puffs in both groups, and ADHD smokers responded more for puffs regardless of condition. Males in both groups worked more for cigarette puffs and made more commission errors on the CPT than females, regardless of condition. Smoking abstinence also increased ratings of withdrawal symptoms in both groups and smokers with ADHD, regardless of condition, reported greater symptoms of arousal, habit withdrawal, and somatic complaints. Across groups, smoking abstinence decreased inhibitory control and increased reaction time variability on the CPT. Abstinence-induced changes in inhibitory control and negative affect significantly predicted smoking-reinforced responding across groups. Conclusions Smokers with ADHD reported higher levels of withdrawal symptoms and worked more for cigarette puffs, regardless of condition, which could help explain higher levels of nicotine dependence and poorer cessation outcomes in this population.

    Cannabis is widely abused, and efficacies of therapeutics for cannabis dependence remain suboptimal. Magnetic resonance imaging (MRI) may aid in the identification of biological markers for successful treatment outcomes (i.e., abstinence). Twenty men with cannabis dependence and twenty non-substance-using healthy comparison (HC) men underwent MRI scanning. Cannabis-dependent individuals then participated in a 12-week randomized clinical trial of behavioral treatments (contingency management (CM), cognitive behavioral therapy (CBT) or both). Pretreatment functional and structural data were compared between the cannabis-dependent and HC participants. In addition, individuals with cannabis dependence were subdivided based on the successful achievement of 21 days of consecutive abstinence during treatment to assess whether abstinent versus non-abstinent cannabis-dependent participants displayed different pretreatment functional and structural characteristics when compared to HC participants. In comparison to HC participants, cannabis-dependent participants demonstrated greater ventral striatal activation during the receipt of losing outcomes and smaller putamenal volumes. Cannabis-dependent participants who did not subsequently achieve 21 days of consecutive abstinence had increased activity within the striatum during the receipt of losing outcomes, relative to HC participants. Cannabis-dependent participants who did not achieve 21 days of abstinence had decreased bilateral putamen volumes prior to treatment, relative to HC participants. Individual differences in pretreatment striatal function and structure may relate to individual differences in treatment responses for cannabis dependence. While mechanisms underlying these associations require further exploration, the striatum might mediate treatment responses via its role in associative reward-learning (e.g., through skills training in CBT or reinforcement of abstinence in CM).

    The Numerical Aerodynamic Simulation (NAS) Systems Division received an Intel Touchstone Sigma prototype model Paragon XP/S- 15 in February, 1993. The i860 XP microprocessor with an integrated floating point unit and operating in dual -instruction mode gives peak performance of 75 million floating point operations (NIFLOPS) per second for 64 bit floating point arithmetic. It is used in the Paragon XP/S-15 which has been installed at NAS, NASA Ames Research Center. The NAS Paragon has 208 nodes and its peak performance is 15.6 GFLOPS. Here, we will report on early experience using the Paragon XP/S- 15. We have tested its performance using both kernels and applications of interest to NAS. We have measured the performance of BLAS 1, 2 and 3 both assembly-coded and Fortran coded on NAS Paragon XP/S- 15. Furthermore, we have investigated the performance of a single node one-dimensional FFT, a distributed two-dimensional FFT and a distributed three-dimensional FFT Finally, we measured the performance of NAS Parallel Benchmarks (NPB) on the Paragon and compare it with the performance obtained on other highly parallel machines, such as CM-5, CRAY T3D, IBM SP I, etc. In particular, we investigated the following issues, which can strongly affect the performance of the Paragon: a. Impact of the operating system: Intel currently uses as a default an operating system OSF/1 AD from the Open Software Foundation. The paging of Open Software Foundation (OSF) server at 22 MB to make more memory available for the application degrades the performance. We found that when the limit of 26 NIB per node out of 32 MB available is reached, the application is paged out of main memory using virtual memory. When the application starts paging, the performance is considerably reduced. We found that dynamic memory allocation can help applications performance under certain circumstances. b. Impact of data cache on the i860/XP: We measured the performance of the BLAS both assembly coded and Fortran

    It is well established that in both food- and drug-addicted individuals there is "dopamine resistance" associated with the DRD2 gene A1 allele. Based on earlier studies, evidence is emerging wherein the potential of utilizing a natural, nonaddicting, safe, putative D2 agonist may play a significant role in the recovery of individuals with reward deficiency syndrome, including those addicted to psychoactive chemicals. Positive outcomes demonstrated by quantitative electroencephalographic (qEEG) imaging in a randomized, triple-blind, placebo-controlled, crossover study involving oral Synaptose Complex KB220Z™ showed an increase of alpha waves and low beta wave activity in the parietal brain region. Using t statistics, significant differences observed between placebo and Synaptose Complex KB220Z™ consistently occurred in the frontal regions after week 1 and then again after week 2 of analyses (P = 0.03). This is the first report to demonstrate involvement of the prefrontal cortex in the qEEG response to a natural putative D2 agonist (Synaptose Complex KB220Z™), especially evident in dopamine D2 A1 allele subjects. Independently, we have further supported this finding with an additional study of 3 serious polydrug abusers undergoing protracted abstinence who carried the DRD2 A1 allele. Significant qEEG differences were found between those who received 1 dose of placebo compared with those who were administered Synaptose Complex KB220Z™. Synaptose Complex KB220Z™ induced positive regulation of the dysregulated electrical activity of the brain in these addicts. The results are indicative of a phase change from low amplitude or low power in the brain to a more regulated state by increasing an average of 6.169 mV(2) across the prefrontal cortical region. In the first experiment we found that while 50% of the subjects carried the DRD2 A1 allele, 100% carried ≥ 1 risk allele. Specifically, based on the proposed addiction risk score for these 14 subjects, 72% had

    Recently Willuhn et al. reported that cocaine use and even non-substance related addictive behavior, increases, as dopaminergic function is reduced. Chronic cocaine exposure has been associated with decreases in D2/D3 receptors, also associated with lower activation to cues in occipital cortex and cerebellum in a recent PET study from Volkow’s group. Therefore, treatment strategies, like dopamine agonist therapy, that might conserve dopamine function may be an interesting approach to relapse prevention in psychoactive drug and behavioral addictions. To this aim, we evaluated the effect of KB220Z™ on reward circuitry of ten heroin addicts undergoing protracted abstinence, an average 16.9 months. In a randomized placebo-controlled crossover study of KB220Z™ five subjects completed a triple blinded–experiment in which the subject, the person administering the treatment and the person evaluating the response to treatment were blinded as to which treatment any particular subject was receiving. In addition, nine subjects total were genotyped utilizing the GARSRX™ test. We preliminarily report that KB220Z ™ induced an increase in BOLD activation in caudate-accumbens-dopaminergic pathways compared to placebo following one-hour acute administration. Furthermore, KB220Z™ also reduced resting state activity in the putamen of abstinent heroin addicts. In the second phase of this pilot study of all ten abstinent heroin-dependent subjects, three brain regions of interest (ROIs) we observed to be significantly activated from resting state by KB220Z compared to placebo (P addiction by direct or indirect dopaminergic interaction. Due to small sample size, we caution definitive interpretation of these preliminary results and confirmation with additional research and ongoing rodent and human studies of KB220Z, is required.

    Full Text Available Background/Aim. Depression is an alcoholism relapse risk factor, but frequently stays underdiagnosed among treated alcoholics. The correlation and characteristics of self-reported and clinically assessed depression in the course of early alcohol abstinence were explored. Methods. A total of 100 inpatient, primary male alcoholics (20-60 years diagnosed according to Classificaton of Mental and Behavioural Disorders (ICD-10 and Diagnostic and Statistical Manual of Mental Disorders (DSM-IV were recruited consecutively. The Hamilton Depression Rating Scale (HDRS and Beck Depression Inventory (BDI were scored on admission (T1, after 4 weeks (T2 and after 8 weeks (T3. Student's t-test, repeated measures ANOVA and Pearson's correlation between the scores were done (p < 0.05. Factor analyses of symptoms were performed. Results: On HDRS T1, T2, T3 90,7%, 39.5%, 17.4% alcoholics were depressive, respectively. The mean HDRS vs BDI scores on T1, T2 and T3 were 15.16 ± 6.34, 7.35 ± 4.18, 4.23 ± 2.93 vs 14.20 ± 9.56, 8.14 ± 7.35, 5.30 ± 4.94, respectively. Depression severity significantly lowered in the course of abstinence (ANOVA. The HRDS and BDI correlations on T1, T2 and T3 were significant (r1 = 0.763, r2 = 0.684, r3 = 0.613 respectively. Dysphoric mood, anxious, vegetative and cognitive HDRS subscales on T1, T2 and T3 were detected, but not BDI factors, thus BDI symptoms were analysed. Conclusions. The majority of alcoholics had depression on admission. A predominant mild-degree with a significant lowering of depression severity and positive significant correlations between HRDS and BDI scores in the course of abstinence were detected. The dysphoric mood on the HDRS sub-scale, and self-blame, anhedonia and guilt BDI symptoms were most prominent and persisted. The BDI could be a useful tool not only for routine screening and reassessment of depression, but also for exploring emotional content during early abstinence and planning tailored

    Chronic exposure to drugs of abuse is linked to long-lasting alterations in the function of limbic system structures, including the nucleus accumbens (NAc). Although cocaine acts via dopaminergic mechanisms within the NAc, less is known about whether phasic dopamine (DA) signaling in the NAc is altered in animals with cocaine self-administration experience or if these animals learn and interact normally with stimuli in their environment. Here, separate groups of rats self-administered either intravenous cocaine or water to a receptacle (controls), followed by 30 d of enforced abstinence. Next, all rats learned an appetitive Pavlovian discrimination and voltammetric recordings of real-time DA release were taken in either the NAc core or shell of cocaine and control subjects. Cocaine experience differentially impaired DA signaling in the core and shell relative to controls. Although phasic DA signals in the shell were essentially abolished for all stimuli, in the core, DA did not distinguish between cues and was abnormally biased toward reward delivery. Further, cocaine rats were unable to learn higher-order associations and even altered simple conditioned approach behaviors, displaying enhanced preoccupation with cue-associated stimuli (sign-tracking; ST) but diminished time at the food cup awaiting reward delivery (goal-tracking). Critically, whereas control DA signaling correlated with ST behaviors, cocaine experience abolished this relationship. These findings show that cocaine has persistent, differential, and pathological effects on both DA signaling and DA-dependent behaviors and suggest that psychostimulant experience may remodel the very circuits that bias organisms toward repeated relapse. SIGNIFICANCE STATEMENT Relapsing to drug abuse despite periods of abstinence and sincere attempts to quit is one of the most pernicious facets of addiction. Unfortunately, little is known about how the dopamine (DA) system functions after periods of drug abstinence

    Distress tolerance has been operationalized as task persistence in stressful behavioral laboratory tasks. According to the distress tolerance perspective, how an individual responds to discomfort/distress predicts early smoking lapses. This theory seems weakly supported by experimental studies since they are limited in number, show inconsistent results, do not include control conditions. We tested the response to a stressful task in smokers under abstinence and under no abstinence to verify if tobacco abstinence reduces task persistence, thus distress tolerance. A placebo-controlled, double-blind, randomized, cross-over design was used. Twenty smokers underwent a breath holding test after the administration of nicotine on one test day and a placebo on another test day. Physiological and psychological variables were assessed at baseline and directly before and after each challenge. Abstinence induced a statistically significant shorter breath holding duration relative to the nicotine condition. No different response to the breath holding test was observed when nicotine and placebo conditions were compared. No response to the breath holding test was found when pre- and post-test values of heart rate, blood pressure, Visual Analogue Scale for fear or discomfort were compared. In brief, tobacco abstinence reduces breath holding duration but breath holding test does not influence discomfort. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Depression is a commonly reported co-morbidity during rehabilitation from alcohol use disorders and its presence is associated with an increased likelihood of relapse. Interventions which impede the development of depression could be of potential benefit if incorporated into treatment programs. We previously demonstrated an ameliorative effect of physical exercise on depressive behaviours in a mouse model of alcohol abstinence. Here, we show that environmental enrichment (cognitive and social stimulation has a similar beneficial effect. The hypothalamic-pituitary-adrenal (HPA axis is a key physiological system regulating stress responses and its dysregulation has been separably implicated in the pathophysiology of depression and addiction disorders. We performed a series of dexamethasone challenges and found that mice undergoing 2 weeks of alcohol abstinence had significantly greater corticosterone and ACTH levels following a DEX-CRH challenge compared to water controls. Environmental enrichment during alcohol abstinence corrected the abnormal DEX-CRH corticosterone response despite a further elevation of ACTH levels. Examination of gene expression revealed abstinence-associated alterations in glucocorticoid receptor (Gr, corticotrophin releasing hormone (Crh and pro-opiomelanocortin (Pomc1 mRNA levels which were differentially modulated by environmental enrichment. Overall, our study demonstrates a benefit of environmental enrichment on alcohol abstinence-associated depressive behaviours and HPA axis dysregulation.

  17. The Korsakoff syndrome: clinical aspects, psychology and treatment.

    2009-01-01

    The Korsakoff syndrome is a preventable memory disorder that usually emerges (although not always) in the aftermath of an episode of Wernicke's encephalopathy. The present paper reviews the clinical and scientific literature on this disorder. A systematic review of the clinical and scientific literature on Wernicke's encephalopathy and the alcoholic Korsakoff syndrome. The Korsakoff syndrome is most commonly associated with chronic alcohol misuse, and some heavy drinkers may have a genetic predisposition to developing the syndrome. The characteristic neuropathology includes neuronal loss, micro-haemorrhages and gliosis in the paraventricular and peri-aqueductal grey matter. Lesions in the mammillary bodies, the mammillo-thalamic tract and the anterior thalamus may be more important to memory dysfunction than lesions in the medial dorsal nucleus of the thalamus. Episodic memory is severely affected in the Korsakoff syndrome, and the learning of new semantic memories is variably affected. 'Implicit' aspects of memory are preserved. These patients are often first encountered in general hospital settings where they can occupy acute medical beds for lengthy periods. Abstinence is the cornerstone of any rehabilitation programme. Korsakoff patients are capable of new learning, particularly if they live in a calm and well-structured environment and if new information is cued. There are few long-term follow-up studies, but these patients are reported to have a normal life expectancy if they remain abstinent from alcohol. Although we now have substantial knowledge about the nature of this disorder, scientific questions (e.g. regarding the underlying genetics) remain. More particularly, there is a dearth of appropriate long-term care facilities for these patients, given that empirical research has shown that good practice has beneficial effects.

    Background Dopamine levels in the prefrontal cortex (PFC) are thought to play an important role in cognitive function and nicotine dependence. The catechol-O-methyltransferase (COMT) inhibitor tolcapone, an FDA-approved treatment for Parkinson’s disease, increases prefrontal dopamine levels, with cognitive benefits that may vary by COMT genotype. We tested whether tolcapone alters working memory-related brain activity and performance in abstinent smokers. Methods In this double-blind crossover study, 20 smokers completed 8 days of treatment with tolcapone and placebo. In both medication periods, smokers completed blood oxygen level-dependent (BOLD) fMRI scans while performing a working memory N-back task after 24 h of abstinence. Smokers were genotyped prospectively for the COMT val158met polymorphism for exploratory analysis. Results Compared to placebo, tolcapone modestly improved accuracy (p = 0.017) and enhanced suppression of activation in the ventromedial prefrontal cortex (vmPFC) (p = 0.002). There were no effects of medication in other a priori regions of interest (dorsolateral PFC, dorsal cingulate/medial prefrontal cortex, or posterior cingulate cortex). Exploratory analyses suggested that tolcapone led to a decrease in BOLD signal in several regions among smokers with val/val genotypes, but increased or remained unchanged among met allele carriers. Tolcapone did not attenuate craving, mood, or withdrawal symptoms compared to placebo. Conclusions Data from this proof-of-concept study do not provide strong support for further evaluation of COMT inhibitors as smoking cessation aids. PMID:24095246

    This paper reports data from a study designed to determine the impact of an 8-week exercise program on depression and anxiety symptoms among newly abstinent methamphetamine (MA)-dependent individuals in residential treatment. One hundred thirty-five MA-dependent individuals, newly enrolled in residential treatment, were randomly assigned to receive either a 3-times-per-week, 60-minute structured exercise program for 8 weeks (24 sessions) or an equivalent number of health education sessions. Using mixed-modeling repeated-measures regression, we examined changes in weekly total depression and anxiety scores as measured by the Beck Depression Inventory and Beck Anxiety Inventory over the 8-week study period. Mean age of participants was 31.7 (SD = 6.9); 70.4% were male and 48% Latino. Analyses indicate a significant effect of exercise on reducing depression (β = -0.63, P = 0.001) and anxiety (β = -0.95, P=0.001) symptoms (total scores) over the 8-week period compared to a health education control group. A significant dose interaction effect between session attendance and exercise was found as well on reducing depression (β = -0.61, P < 0.001) and anxiety symptoms (β = -0.22, P=0.009) over time compared to the control group. Results support the role of a structured exercise program as an effective intervention for improving symptoms of depression and anxiety associated with MA abstinence. Copyright © 2015 Elsevier Inc.

  3. Transforming growth factor beta receptor 1 is increased following abstinence from cocaine self-administration, but not cocaine sensitization.

    Directory of Open Access Journals (Sweden)

    Amy M Gancarz-Kausch

    Full Text Available The addicted phenotype is characterized as a long-lasting, chronically relapsing disorder that persists following long periods of abstinence, suggesting that the underlying molecular changes are stable and endure for long periods even in the absence of drug. Here, we investigated Transforming Growth Factor-Beta Type I receptor (TGF-β R1 expression in the nucleus accumbens (NAc following periods of withdrawal from cocaine self-administration (SA and a sensitizing regimen of non-contingent cocaine. Rats were exposed to either (i repeated systemic injections (cocaine or saline, or (ii self-administration (cocaine or saline and underwent a period of forced abstinence (either 1 or 7 days of drug cessation. Withdrawal from cocaine self-administration resulted in an increase in TGF-β R1 protein expression in the NAc compared to saline controls. This increase was specific for volitional cocaine intake as no change in expression was observed following a sensitizing regimen of experimenter-administered cocaine. These findings implicate TGF-β signaling as a novel potential therapeutic target for treating drug addiction.

    Opioid withdrawal syndrome is a debilitating manifestation of opioid dependence and responds poorly to the available clinical therapies. Studies from various in vivo and in vitro animal models of opioid withdrawal syndrome have led to understanding of its pathobiology which includes complex interrelated pathways leading to adenylyl cyclase superactivation based central excitation. Advancements in the elucidation of opioid withdrawal syndrome mechanisms have revealed a number of key targets that have been hypothesized to modulate clinical status. The present review discusses the neurobiology of opioid withdrawal syndrome and its therapeutic target recptors like calcitonin gene related peptide receptors (CGRP), N-methyl-D-aspartate (NMDA) receptors, gamma aminobutyric acid receptors (GABA), G-proteingated inwardly rectifying potassium (GIRK) channels and calcium channels. The present review further details the potential role of second messengers like calcium (Ca2+) / calmodulin-dependent protein kinase (CaMKII), nitric oxide synthase, cytokines, arachidonic acid metabolites, corticotropin releasing factor, fos and src kinases in causing opioid withdrawal syndrome. The exploitation of these targets may provide effective therapeutic agents for the management of opioid dependence-induced abstinence syndrome.

    2017-11-01

    Previous research has examined clinicians' acceptance of non-abstinence for clients who have a substance use disorder (SUD), but many SUD clients also present with a psychiatric disorder. To evaluate the acceptability of non-abstinence as a final outcome goal for clients with co-occurring diagnoses, we recruited a nationwide sample of 751 American substance abuse counselors to complete a web-based questionnaire. Respondents rated the acceptability of limited/moderate consumption by clients diagnosed with each of 18 co-occurring disorders: three psychiatric disorders (Major Depressive Disorder, Post-Traumatic Stress Disorder, Social Phobia) x three substances (alcohol, cannabis, opioids) x two levels of severity (DSM-5 Moderate SUD, DSM-5 Severe SUD). On average, non-abstinence was rated as unacceptable for clients with any of the 18 diagnostic pairs, although one-fourth to almost one-third rated limited/moderate use of cannabis somewhat or completely acceptable for clients diagnosed with a Moderate Cannabis Use Disorder when paired with any of the three psychiatric disorders. Furthermore, small proportions of respondents (13% to 20%) rated non-abstinence at least somewhat acceptable even when clients were diagnosed with a Severe SUD for any of the three substances and any co-occurring psychiatric disorder. Based on our findings, clients with co-occurring disorders who want to moderate their substance use will typically find their counselor does not accept that outcome goal. Because supporting non-abstinence respects client autonomy, could attract and retain clients in counseling, and is consistent with a recovery-oriented treatment model, we encourage continuing education about the benefits of non-abstinence as a treatment goal for clients with co-occurring disorders.

    Hogarth, Lee; Mathew, Amanda R; Hitsman, Brian

    2017-07-01

    Although depression and smoking commonly co-occur, the mechanisms underpinning this association are poorly understood. One hypothesis is that depression promotes tobacco dependence, persistence and relapse by increasing sensitivity to acute negative mood and abstinence induced tobacco-seeking behavior. Twenty nine daily smokers of >10 cigarettes per day, nine with major depression and 20 without, completed two laboratory sessions one week apart, smoking as normal prior to session 1 (sated session), and 6h abstinent prior to session 2 (abstinent session). In both sessions, tobacco-seeking was measured at baseline by preference to view smoking versus food images. Negative mood was then induced by negative ruminative statements and sad music, before tobacco-seeking was measured again at test. In the sated session, negative mood induction produced a greater increase in tobacco choice from baseline to test in depressed (pchoice between the sated and abstinent sessions in depressed (p=0.002, η p 2 =0.771) compared to non-depressed smokers (p=0.22, η p 2 =0.089, interaction: p=0.023, η p 2 =0.189). These mood and abstinence induced increases in tobacco choice were positively associated with depression symptoms across the sample as a whole (ps≤0.04, η p 2 ≥0.159), and correlated with each other (r=0.67, pmood and abstinence induced tobacco-seeking behavior. Treatments should seek to break the association between adverse states and smoking to cope. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background Cannabis is widely abused, and efficacies of therapeutics for cannabis dependence remain suboptimal. Magnetic resonance imaging (MRI) may aid in the identification of biological markers for successful treatment outcomes (i.e., abstinence). Methods Twenty men with cannabis dependence and twenty non-substance-using healthy comparison (HC) men underwent MRI scanning. Cannabis-dependent individuals then participated in a 12-week randomized clinical trial of behavioral treatments (contingency management (CM), cognitive behavioral therapy (CBT) or both). Pretreatment functional and structural data were compared between the cannabis-dependent and HC participants. In addition, individuals with cannabis dependence were subdivided based on the successful achievement of 21 days of consecutive abstinence during treatment to assess whether abstinent versus nonabstinent cannabis-dependent participants displayed different pretreatment functional and structural characteristics when compared to HC participants. Results In comparison to HC participants, cannabis-dependent participants demonstrated greater ventral striatal activation during the receipt of losing outcomes and smaller putamenal volumes. Cannabis-dependent participants who did not subsequently achieved 21 days of consecutive abstinence had increased activity within the striatum during the receipt of losing outcomes, relative to HC participants. Cannabis-dependent participants who did not achieve 21 days of abstinence had decreased bilateral putamen volumes prior to treatment, relative to HC participants. Conclusions Individual differences in pretreatment striatal function and structure may relate to individual differences in treatment responses for cannabis dependence. While mechanisms underlying these associations require further exploration, the striatum might mediate treatment responses via its role in associative reward-learning (e.g., through skills training in CBT or reinforcement of abstinence in CM

  8. Systematic evaluation of "compliance" to prescribed treatment medications and "abstinence" from psychoactive drug abuse in chemical dependence programs: data from the comprehensive analysis of reported drugs.

    Full Text Available This is the first quantitative analysis of data from urine drug tests for compliance to treatment medications and abstinence from drug abuse across "levels of care" in six eastern states of America. Comprehensive Analysis of Reported Drugs (CARD data was used in this post-hoc retrospective observational study from 10,570 patients, filtered to include a total of 2,919 patients prescribed at least one treatment medication during 2010 and 2011. The first and last urine samples (5,838 specimens were analyzed; compliance to treatment medications and abstinence from drugs of abuse supported treatment effectiveness for many. Compared to non-compliant patients, compliant patients were marginally less likely to abuse opioids, cannabinoids, and ethanol during treatment although more likely to abuse benzodiazepines. Almost 17% of the non-abstinent patients used benzodiazepines, 15% used opiates, and 10% used cocaine during treatment. Compliance was significantly higher in residential than in the non-residential treatment facilities. Independent of level of care, 67.2% of the patients (n = 1963; P<.001 had every treatment medication found in both first and last urine specimens (compliance. In addition, 39.2% of the patients (n = 1143; P<.001 had no substance of abuse detected in either the first or last urine samples (abstinence. Moreover, in 2010, 16.9% of the patients (n = 57 were abstinent at first but not at last urine (deteriorating abstinence, the percentage dropped to 13.3% (n = 174 in 2011; this improvement over years was statistically significant.

    We report the highest mobility values above 2000 cm 2 /Vs in Si doped GaNAs film grown by molecular beam epitaxy. To understand the feature of the origin which limits the electron mobility in GaNAs, temperature dependences of mobility were measured for high mobility GaNAs and referential low mobility GaInNAs. Temperature dependent mobility for high mobility GaNAs is similar to the GaAs case, while that for low mobility GaInNAs shows large decrease in lower temperature region. The electron mobility of high quality GaNAs can be explained by intrinsic limiting factor of random alloy scattering and extrinsic factor of ionized impurity scattering.

  10. Concreto submetido a vibrações nas primeiras idades

    J. F. Fernandes

    Full Text Available Este artigo traz informações sobre o comportamento nas primeiras idades de um concreto de alta resistência, produzido com cimento de alta resistência inicial, lançado e adensado em ambientes submetidos a vibrações, como em obras de pontes de rodovias. Apresenta-se o programa experimental desenvolvido, descrevendo desde a moldagem dos corpos-de-prova, sob ação de vibrações similares às induzidas pelo tráfego, até os ensaios de caracterização mecânica e de aderência aço-concreto. Os resultados experimentais indicam que o concreto submetido à vibração nas primeiras idades pode sofrer perdas na resistência à tração e no módulo de elasticidade. A redução dessas propriedades pode comprometer a utilização da estrutura devido ao aparecimento de flechas e fissuras acima dos limites de norma. A redução da resistência à tração do concreto deve ser considerada, também, na aplicação de pavimentos rígidos, onde essa propriedade é fundamental para garantir a durabilidade do sistema. Não foi observada nenhuma redução na resistência à compressão ou na capacidade de aderência devido à introdução de vibrações nas primeiras idades do concreto.

    Full Text Available The urofacial syndrome is characterized by functional obstructive uropathy asso-ciated with an inverted smile. The importance of the subject is that it sheds light, not only on the muscles of facial expression, but also on the inheritance of voiding disorders and lower urinary tract malformations. We report a 10-year-old-male patient who had the urofacial syndrome. Early diagnosis of the urofacial syndrome is important to avoid upper urinary tract damage and renal failure.

    Full Text Available O presente artigo insere-se em projeto de pesquisa-intervenção sobre a música e suas articulações identitárias nas corporações musicais da região dos Campos das Vertentes, em especial São João del-Rei e cidades vizinhas. Nessa região, a música tem papel significativo na formação da identidade cultural dos cidadãos e na história dos municípios. O recorte atual apresenta uma investigação sobre determinações de gênero, visando conhecer como se dá a participação de musicistas nas bandas e orquestras da região. Para tanto, utilizou-se a análise arqueológica do discurso, a fim de contrapor falas de musicistas às falas de músicos das corporações e, também, às falas masculinas presentes na filosofia e ao discurso utópico sobre a mulher. Observou-se que as diferenças de gênero tradicionais conservam-se encobertas no cotidiano das corporações musicais. Entretanto, observou-se também que as musicistas começam a ser reconhecidas nas corporações e, sobretudo, reconhecem-se como capazes de, nelas, alçarem voos.

    The goal of the Numerical Aerodynamic Simulation (NAS) Program is to provide a powerful computational environment for advanced research and development in aeronautics and related disciplines. The present NAS system consists of a Cray 2 supercomputer connected by a data network to a large mass storage system, to sophisticated local graphics workstations, and by remote communications to researchers throughout the United States. The program plan is to continue acquiring the most powerful supercomputers as they become available. In the 1987/1988 time period it is anticipated that a computer with 4 times the processing speed of a Cray 2 will be obtained and by 1990 an additional supercomputer with 16 times the speed of the Cray 2. The implications of this 20-fold increase in processing power on the data communications requirements are described. The analysis was based on models of the projected workload and system architecture. The results are presented together with the estimates of their sensitivity to assumptions inherent in the models.

    The UAS-NAS Project demo will showcase recent research efforts to ensure the interoperability between proposed UAS detect and avoid (DAA) human machine interface requirements (developed within RTCA SC-228) and existing collision avoidance displays. Attendees will be able to view the current state of the art of the DAA pilot traffic, alerting and guidance displays integrated with Traffic advisory and Collision Avoidance (TCAS) II in the UAS-NAS Project's research UAS ground control station (developed in partnership with the Air Force Research Laboratory). In addition, attendees will have the opportunity to interact with the research UAS ground control station and "fly" encounters, using the DAA and TCAS II displays to avoid simulated aircraft. The display of the advisories will be hosted on a laptop with an external 30" monitor, running the Vigilant Spirit system. DAA advisories will be generated by the JADEM software tool, connected to the system via the LVC Gateway. A repeater of the primary flight display will be shown on a 55" monitor mounted on a stand at the back of the booth to show the pilot interaction to the passersby.

    Szreter, Simon; Fisher, Kate

    2010-06-10

    This article presents an exploration of qualitative evidence on the relationship between birth control and abstinence from an oral history project, which interviewed middle and working-class English men and women, who had married between the late 1920s and the early 1950s. Among the working classes the assumption that men were responsible for birth control choices and the disadvantages that contraceptive methods of all types posed, combined with the fear of pregnancy, acted as a disincentive to have sex and resulted in forms of partial abstinence. Among the middle classes, women had much more access to birth control information and as a consequence a greater range of methods was used, including more female methods. However, the reluctance of couples to discuss sexual matters, and some continued preference for male methods meant that while condoms were the most regularly used middle-class male method, both withdrawal and abstinence were also in evidence. Moreover, although partners were more likely to discuss birth control at the start of their marriages, they were less likely to agree that contraception was a male responsibility and there was greater potential for conflict over contraceptive methods, not infrequently resulting in abstinence. The evidence suggests that sexual and contraceptive practices in marriages in England at the end of the secular fertility decline do not present a picture which straightforwardly correlates with the assumptions represented by the popular thesis that this period of increased fertility control was closely associated with the rise of companionate marriage.

  8. Monetary-based consequences for drug abstinence: methods of implementation and some considerations about the allocation of finances in substance abusers.

    Dallery, Jesse; Raiff, Bethany

    2012-01-01

    Conceptualizing drug abuse within the framework of behavioral theories of choice highlights the relevance of environmental variables in shifting behavior away from drug-related purchases. Choosing to use drugs results in immediate and certain consequences (e.g., drug high and relief from withdrawal), whereas choosing abstinence typically results in delayed, and often uncertain, consequences (e.g., improved health, interpersonal relationships, money). This is a selective review of the literature on Contingency management (CM). We highlight a variety of methods to deliver CM in practical, effective, and sustainable ways. We consider a number of parameters that are critical to the success of monetary-based CM, and the role of the context in influencing CM's effects. To illustrate the broad range of applications of CM, we also review different methods for arranging contingencies to promote abstinence and other relevant behavior. Finally, we discuss some considerations about how drug-dependent individuals allocate their finances in the context of CM interventions. Contingency management (CM) increases choice for drug abstinence via the availability of immediate, financial-based gains, contingent on objective evidence of abstinence.

    Long-term Therapeutic Workplace effects were evaluated in heroin- and cocaine-dependent, unemployed, treatment-resistant young mothers. Participants were paid to work or to train in the Therapeutic Workplace but had to provide drug-free urine samples to gain daily access. Participants (N = 40) were randomly assigned to a Therapeutic Workplace or usual care control group. Therapeutic Workplace participants could work for 3 years. Relative to controls, Therapeutic Workplace participants increased cocaine (28% vs. 54% negative; p = .04) and opiate (37% vs. 60% negative; p = .05) abstinence on the basis of monthly urine samples collected until 3 years after intake. The Therapeutic Workplace can be an effective long-term treatment of cocaine and heroin addiction in poor and chronically unemployed young mothers.

  12. A Z-linked sterility locus causes sexual abstinence in hybrid females and facilitates speciation in Spodoptera frugiperda.

    In the fall armyworm, Spodoptera frugiperda (Lepidoptera, Noctuidae), two sympatric strains have been recognized that have been termed corn strain (C) and rice strain (R), referring to their most common host plants. Both strains are reproductively isolated via a distinct prezygotic barrier as well as via an intriguing postzygotic phenomenon: when R females have mated with C males, the resulting RC hybrid females exhibit dramatically reduced fertility independent of their mating partner. Here, we demonstrate that the reduced fertility is caused by the fact that these females refrain from mating, that is, females are behaviorally sterile. We identified a Z-chromosomally linked sterility locus that is most likely incompatible with yet to be identified autosomal (or cytoplasmic) factors, leading to the observed sexual abstinence. Within-chromosome mapping revealed the sterility locus to be located in an area of strongly reduced interstrain recombination. © 2016 The Author(s).

    2013-01-01

    The purpose of this research was to conduct a preliminary evaluation of the Abstinence and Contraception Education Storehouse (ACES), a digital, classroom-based resource designed to supplement existing sex education curricula with highly interactive materials such as video clips, multimedia polls and quizzes, and audiovisual demonstrations. 335 students ages 14-19 were randomly assigned to an ACES-based (treatment) or a standard (control) sex education curriculum. Data were collected at the onset of the intervention and 3-months after the completion of the intervention. Preliminary results were highly encouraging, with ACES participants who were sexually initiated at baseline reporting at the 3-month follow-up significant reductions in the number of times they had sex in the past four weeks. Both sexually initiated and non-sexually initiated youth who experienced the ACES curriculum also demonstrated greater intent to abstain from the sex during the follow-up period than those in the control group.

    The high energetic demand of parental care requires parents to direct their resources towards the support of existing offspring rather than investing into the production of additional young. However, how such a resource flow is channelled appropriately is poorly understood. In this study, we provide the first comprehensive analysis of the physiological mechanisms coordinating parental and mating effort in an insect exhibiting biparental care. We show a hormone-mediated infertility in female burying beetles during the time the current offspring is needy and report that this temporary infertility is communicated via a pheromone to the male partner, where it inhibits copulation. A shared pathway of hormone and pheromone system ensures the reliability of the anti-aphrodisiac. Female infertility and male sexual abstinence provide for the concerted investment of parental resources into the existing developing young. Our study thus contributes to our deeper understanding of the mechanisms underlying adaptive parental decisions.

    Abstinence-only sexuality education (AOSE); is required in the public school systems of many states, raising public health concerns and perpetuating health disparities through school systems. This study aimed to determine the correlations between state-mandated AOSE and the rates of adolescent HIV and teen pregnancy. Using publicly available data on all 50 United States' laws and policies on AOSE, states were ranked according to their level of abstinence emphasis on sexuality education (Level 0 - Level 3);. We calculated the relative proportion of Black students in public schools and the proportion of families below the federal poverty line then ranked them by state. We compared the states' ranks to the incidence of adolescent HIV and teen pregnancy in those states to identify associations between variables. The majority of states (~44 percent ); have legally mandated AOSE policies (Level 3); and adolescent HIV and teen pregnancy rates were highest in these Level 3 states. There were significant, positive correlations between HIV incidence rates of 13-19 year olds, HIV rates of 20-24 year olds, teen pregnancy rates, and AOSE level, with the proportion of the population that lives below the federal poverty level, and whether they attended schools that had a greater than 50 percent of an African American population. These data show a clear association between state sexuality education policies and adolescent HIV and teen pregnancy rates not previously demonstrated. Our data further show that states that have higher proportions of at-risk populations, with higher adolescent HIV and teen pregnancy rates, are more likely to also have restrictive AOSE policies. These populations may be more likely to attend public schools where AOSE is taught, increasing their risk for HIV and teen pregnancy. The World Health Organization considers fact-based Comprehensive Sexuality Education a human right, and the authors believe it is past time to end harmful, discriminatory sexuality

  16. Robust Escalation of Nicotine Intake with Extended Access to Nicotine Self-Administration and Intermittent Periods of Abstinence

    Although established smokers have a very regular pattern of smoking behavior, converging lines of evidence suggest that the escalation of smoking behavior is a critical factor in the development of dependence. However, the neurobiological mechanisms that underlie the escalation of smoking are unknown, because there is no animal model of the escalation of nicotine intake. On the basis of the pattern of smoking behavior in humans and presence of monoamine oxidase inhibitors in tobacco smoke, we hypothesized that the escalation of nicotine intake may only occur when animals are given extended-access (21 h per day) self-administration sessions after repeated periods of abstinence (24–48 h), and after chronic inhibition of monoamine oxidase using phenelzine sulfate. Intermittent access (every 24–48 h) to extended nicotine self-administration produced a robust escalation of nicotine intake, associated with increased responding under fixed- and progressive-ratio schedules of reinforcement, and increased somatic signs of withdrawal. The escalation of nicotine intake was not observed in rats with intermittent access to limited (1 h per day) nicotine self-administration or daily access to extended (21 h per day) nicotine self-administration. Moreover, inhibition of monoamine oxidase with daily administration of phenelzine increased nicotine intake by ∼50%. These results demonstrate that the escalation of nicotine intake only occurs in animals given intermittent periods of abstinence with extended access to nicotine, and that inhibition of monoamine oxidase may contribute to the escalation of smoking, thus validating both an animal model of the escalation of smoking behavior and the contribution of monoamine oxidase inhibition to compulsive nicotine-seeking.

    Women's addiction to alcohol remains a taboo subject, whereas one third of alcohol-dependent people are female. Social representations concerning them are very unfavorable. Their alcoholism is usually accompanied by strong feelings of guilt, depreciation and lowered self-esteem. There is little existing work about self-esteem in women who have become abstinent. This study's goal is to compare the self-esteem of women who are alcohol-dependent and the self-esteem of women who have become abstinent in various domains (social, familial, professional). The sample contained 71 women divided into three groups: 31 alcohol-dependent women (average age of 44.9); 20 alcohol-dependent women who had become abstinent for at least two months (average age of 44.7) and 20 women who formed the control group (average age of 44.4). The material was put together from the Self-Esteem Inventory (SEI, adult version of Coopersmith 1981). It includes 58 items divided into four sub-categories (general self-esteem, social, familial and professional) and a scale for falsehoods. The SEI was self-administered. The statistics were produced entirely with non-parametric tests: Mann-Whitley U Test for the comparison of two independent samples and Kruskal-Wallis Anova for the comparison of three independent samples. A significant difference was found for general self-esteem (P=0.001), familial (P=0.01) and professional (P=0.03) between the three groups of women (alcohol-dependent, alcohol-dependent who had become abstinent and women from the control group). There was no statistical difference for social self-esteem or the lying scale. There was a difference between alcohol-dependent women and the control group in general self-esteem (P=0.0001), familial self-esteem (P=0.01) and professional self-esteem (P=0.002), as well as between women who had become abstinent and women from the control group in general self-esteem (P=0.02), familial self-esteem (P=0.005) and professional self-esteem (P=0.07; ns

    Does physical exercise in addition to a multicomponent smoking cessation program increase abstinence rate and suppress weight gain? An intervention study Tobacco use is considered the single most preventable cause of premature morbidity and mortality. Smoking cessation programs aim at two interrelated purposes, to help people to give up smoking and to prevent relapse. A multicomponent intervention consisting of nicotine replacement therapy, health education, behaviour modification therapy and counselling is widely recommended in the health care literature. Smoking cessation studies from a nursing perspective are few. The purpose of this quasi-experimental study was to compare outcomes of two nurse-managed 1-year group smoking cessation interventions. Intervention 1 (n=34) was provided at a health care centre and consisted of nicotine replacement therapy, health education, behavioural modification and individual and group counselling. In intervention 2 (n=33), provided in a health club, physical exercise was added to the intervention provided in 1. Participants were self-referred with equal numbers in both interventions. A nonsignificant difference in lapse free abstinence time (LFAT) at 1 year was demonstrated between intervention 1 (20.6%, n=7) and intervention 2 (39.4%, n=13) (p=0.16, odds ratio=2.5). The difference in weight gain between intervention groups was also nonsignificant. Within intervention comparison between abstinent participants and smokers showed that abstinent participants had gained significantly more weight than smokers in intervention 2 (p=0.001), but in intervention 1 the difference was nonsignificant (p=0.2). The small sample size in the study detracts from the significance of the findings. However, a trend is observed showing that physical exercise increases the abstinence rate of participants. The conclusion is drawn that a multicomponent smoking cessation program that includes physical exercise might be an effective intervention, but

    TAFRO syndrome is a newly recognized variant of idiopathic multicentric Castleman disease (iMCD) that involves a constellation of syndromes: thrombocytopenia (T), anasarca (A), fever (F), reticulin fibrosis (R), and organomegaly (O). Thrombocytopenia and severe anasarca accompanied by relatively low serum immunoglobulin levels are characteristic clinical findings of TAFRO syndrome that are not present in iMCD-not otherwise specified (iMCD-NOS). Lymph node biopsy is recommended to exclude other diseases and to diagnose TAFRO syndrome, which reveals characteristic histopathological findings similar to hyaline vascular-type CD. TAFRO syndrome follows a more aggressive course, compared with iMCD-NOS, and there is no standard treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

  12. Sobre a Pesquisa nas Artes: um discurso amoroso

    Directory of Open Access Journals (Sweden)

    Victoria Pérez Royo

    2015-09-01

    Full Text Available Este artigo resulta de um exercício de reescrita experimental e de um pensamento analógico cujo objetivo era abrir uma nova perspectiva sobre pesquisa nas artes. Metodologicamente, as diferentes figuras de amor no livro Fragmentos de um Discurso Amoroso, de Barthes, são levadas a conversar sobre a relação entre pesquisador e objeto de estudo. Essa analogia nos permite encontrar parâmetros de qualidade baseados em uma escala de valores diferentes dos hegemônicos na academia (produtividade, competitividade, inovação. Esses novos parâmetros podem constituir uma sólida base ontológica para a construção de uma nova política de pesquisa artística na academia que permita uma reconsideração radical dos processos de investigação em artes.

    2006-02-01

    Recently there has been a great deal of interest in the growth of dilute nitride quaternary alloys, such as InGaNAs, on GaAs substrates for the fabrication of GaAs-based components and optoelectronic integrated circuits. The addition of indium to the binary compound GaAs produces a ternary with a lower bandgap and larger lattice constant. The incorporation of nitrogen in this ternary further decreases the bandgap while reducing the lattice constant. This makes it possible to grow material lattice-matched to a GaAs substrate but with a narrower bandgap offering the possibility of growing materials suitable for opto-electronic devices on a GaAs substrate while operating at wavelengths used in long-distance optical communications. These devices can then be integrated with mature GaAs device technologies (MESFET, HBT) in photoreceivers and receivers/transmitters for improved functionality and reliability, lower cost, reduced size, etc. We have fabricated metal-semiconductor-metal (MSM) photodetectors on 1-μm thick In .1Ga .9N .03As .97 epilayers, a composition that results in a bandgap in the 1.3 μm region. We report on the DC characteristics, frequency dependence and wavelength dependence of the photoresponse. The results are compared to MSMs fabricated on GaAs. The temporal response is not as fast as that of GaAs MSMs and may be related to low carrier mobility. This shortcoming has been reported as the cause for the lower-than-expected efficiency of solar cells fabricated using this quarternary. The effect of growth conditions and thermal processing on detector characteristics such as bandwidth and dark current were investigated. The challenges associated with the use of InGaNAs in photodetectors (such as defects, response speed, requirement for thermal anneal) will be discussed.

    Full Text Available Este estudo trata de refletir sobre as potencialidades/operacionalidades das práticas pedagógicas da Geografia na apropriação das redes sociais online. Para isso, analisamos possíveis potencialidades oferecidas pelas redes sociais online para a Geografia e como podem ser operacionalizadas nas práticas pedagógicas com as redes sociais online seu ensino e, também, pensar como elas podem contribuir para ensinar e aprender com mais significância Geografia. Os fios teóricos da pesquisa estão tramados no entendimento de aprendizagem online para emaranhar os conceitos de espaço e ciberespaço, transitando por dois locais fundamentais: o da escola e o das redes. A abordagem metodológica é construída nas trilhas das pesquisas pós-críticas em educação, onde o Facebook é o lócus para analisar as novas formas de comunicar que subjetivam os sujeitos e engendram novos formatos de ensinagem. Os resultados apontam diferentes potencialidades e operacionalidades das redes sociais online, mas que não representam apenas o uso da técnica em sala de aula, mas sim como parte da agenda de busca pela construção de processos de aprendizagens significativos em Geografia, através das redes sociais, que representam uma forma contemporânea de comunicar/interagir presente no cotidiano dos alunos.

    Full Text Available Abstract CHARGE syndrome was initially defined as a non-random association of anomalies (Coloboma, Heart defect, Atresia choanae, Retarded growth and development, Genital hypoplasia, Ear anomalies/deafness. In 1998, an expert group defined the major (the classical 4C's: Choanal atresia, Coloboma, Characteristic ears and Cranial nerve anomalies and minor criteria of CHARGE syndrome. Individuals with all four major characteristics or three major and three minor characteristics are highly likely to have CHARGE syndrome. However, there have been individuals genetically identified with CHARGE syndrome without the classical choanal atresia and coloboma. The reported incidence of CHARGE syndrome ranges from 0.1–1.2/10,000 and depends on professional recognition. Coloboma mainly affects the retina. Major and minor congenital heart defects (the commonest cyanotic heart defect is tetralogy of Fallot occur in 75–80% of patients. Choanal atresia may be membranous or bony; bilateral or unilateral. Mental retardation is variable with intelligence quotients (IQ ranging from normal to profound retardation. Under-development of the external genitalia is a common finding in males but it is less apparent in females. Ear abnormalities include a classical finding of unusually shaped ears and hearing loss (conductive and/or nerve deafness that ranges from mild to severe deafness. Multiple cranial nerve dysfunctions are common. A behavioral phenotype for CHARGE syndrome is emerging. Mutations in the CHD7 gene (member of the chromodomain helicase DNA protein family are detected in over 75% of patients with CHARGE syndrome. Children with CHARGE syndrome require intensive medical management as well as numerous surgical interventions. They also need multidisciplinary follow up. Some of the hidden issues of CHARGE syndrome are often forgotten, one being the feeding adaptation of these children, which needs an early aggressive approach from a feeding team. As the child

    Gastric Outlet Obstruction (GOO) due to impaction of a gallstone in the duodenum after migration through a bilioduodenal fistula is known as Bouveret's syndrome. Its clinical symptoms are entirely vague and nonspecific. Because of its rarity, insidiousness and unpredictable symptomatology. Bouveret's syndrome is never thought of in the differential diagnosis as aetiology of gastric outlet obstruction. Recent advances in fiberoptics technology, advent of modern imaging modalities and minimally-invasive techniques like endoscopy and laparoscopy has brought a great revolution in the management of Bouveret's syndrome and have tremendously decreased morbidity and mortality associated with this rare clinical entity.

  19. Neuroacanthocytosis Syndromes

    Directory of Open Access Journals (Sweden)

    Walker Ruth H

    2011-10-01

    Full Text Available Abstract Neuroacanthocytosis (NA syndromes are a group of genetically defined diseases characterized by the association of red blood cell acanthocytosis and progressive degeneration of the basal ganglia. NA syndromes are exceptionally rare with an estimated prevalence of less than 1 to 5 per 1'000'000 inhabitants for each disorder. The core NA syndromes include autosomal recessive chorea-acanthocytosis and X-linked McLeod syndrome which have a Huntington´s disease-like phenotype consisting of a choreatic movement disorder, psychiatric manifestations and cognitive decline, and additional multi-system features including myopathy and axonal neuropathy. In addition, cardiomyopathy may occur in McLeod syndrome. Acanthocytes are also found in a proportion of patients with autosomal dominant Huntington's disease-like 2, autosomal recessive pantothenate kinase-associated neurodegeneration and several inherited disorders of lipoprotein metabolism, namely abetalipoproteinemia (Bassen-Kornzweig syndrome and hypobetalipoproteinemia leading to vitamin E malabsorption. The latter disorders are characterized by a peripheral neuropathy and sensory ataxia due to dorsal column degeneration, but movement disorders and cognitive impairment are not present. NA syndromes are caused by disease-specific genetic mutations. The mechanism by which these mutations cause neurodegeneration is not known. The association of the acanthocytic membrane abnormality with selective degeneration of the basal ganglia, however, suggests a common pathogenetic pathway. Laboratory tests include blood smears to detect acanthocytosis and determination of serum creatine kinase. Cerebral magnetic resonance imaging may demonstrate striatal atrophy. Kell and Kx blood group antigens are reduced or absent in McLeod syndrome. Western blot for chorein demonstrates absence of this protein in red blood cells of chorea-acanthocytosis patients. Specific genetic testing is possible in all NA syndromes

  2. Adolescent abstinence and unprotected sex in CyberSenga, an Internet-based HIV prevention program: randomized clinical trial of efficacy.

    Directory of Open Access Journals (Sweden)

    Michele L Ybarra

    Full Text Available Cost-effective, scalable programs are urgently needed in countries deeply affected by HIV.This parallel-group RCT was conducted in four secondary schools in Mbarara, Uganda. Participants were 12 years and older, reported past-year computer or Internet use, and provided informed caregiver permission and youth assent. The intervention, CyberSenga, was a five-hour online healthy sexuality program. Half of the intervention group was further randomized to receive a booster at four-months post-intervention. The control arm received 'treatment as usual' (i.e., school-delivered sexuality programming. The main outcome measures were: 1 condom use and 2 abstinence in the past three months at six-months' post-intervention. Secondary outcomes were: 1 condom use and 2 abstinence at three-month's post-intervention; and 6-month outcomes by booster exposure. Analyses were intention to treat.All 416 eligible youth were invited to participate, 88% (n = 366 of whom enrolled. Participants were randomized to the intervention (n = 183 or control (n = 183 arm; 91 intervention participants were further randomized to the booster. No statistically significant results were noted among the main outcomes. Among the secondary outcomes: At three-month follow-up, trends suggested that intervention participants (81% were more likely to be abstinent than control participants (74%; p = 0.08, and this was particularly true among youth who were abstinent at baseline (88% vs. 77%; p = 0.02. At six-month follow-up, those in the booster group (80% reported higher rates of abstinence than youth in the intervention, no booster (57% and control (55% groups (p = 0.15; they also reported lower rates of unprotected sex (5% compared to youth in the intervention, no booster (24% and control (21% groups (p = 0.21 among youth sexually active at baseline.The CyberSenga program may affect HIV preventive behavior among abstinent youth in the short term and, with the

    2011-06-01

    At least 60% of those treated for an alcohol use disorder will relapse. Empirical study of the integrity of the brain reward system (BRS) is critical to understanding the mechanisms of relapse as this collection of circuits is implicated in the development and maintenance of all forms of addictive disorders. This study compared thickness, surface area, and volume in neocortical components of the BRS among nonsmoking light-drinking controls (controls), individuals who remained abstinent and those who relapsed after treatment. Seventy-five treatment-seeking alcohol-dependent individuals (abstinent for 7±3 days) and 43 controls completed 1.5T proton magnetic resonance imaging studies. Parcellated morphological data were obtained for following bilateral components of the BRS: rostral and caudal anterior cingulate cortex, insula, medial and lateral orbitofrontal cortex (OFC), rostral and caudal middle and superior frontal gyri, amygdala and hippocampus as well as for 26 other bilateral neocortical regions. Alcohol-dependent participants were followed over 12-months after baseline study and were classified as abstainers (no alcohol consumption; n=24) and relapsers (any alcohol consumption; n=51) at follow-up. Relapsers and abstainers demonstrated lower cortical thickness in the vast majority of BRS regions as well as lower global thickness compared to controls. Relapsers had lower total BRS surface area than both controls and abstainers, but abstainers were not significantly different from controls on any surface area measure. Relapsers demonstrated lower volumes than controls in the majority of regions, while abstainers showed lower volumes than controls in the superior frontal gyrus, insula, amygdala, and hippocampus, bilaterally. Relapsers exhibited smaller volumes than abstainers in the right rostral middle and caudal middle frontal gyri and the lateral OFC, bilaterally. In relapsers, lower baseline volumes and surface areas in multiple regions were associated with

    2017-01-01

    Smokers who wish to quit may refrain from doing so if they expect to experience more stress after haven given up. We test if stress-related expectations about smoking cessation are associated with quit attempts and abstinence among smokers who are motivated to quit. The study included 1809 daily...... after 3, 8 and 14 months. We found that the association between expecting to be more stressed if giving up smoking differed between participants who had previously attempted to quit and those who had not: In participants who previously attempted to quit (47%), expecting to be more stressed......, expectations about stress were not associated with abstinence. Results indicate that expectations about stress in relation to smoking cessation are an important determinant of cessation in smokers who previously attempted to quit.

    Full Text Available O presente trabalho tem por objetivo analisar propagandas de cervejas que circulam na mídia, observando as marcas de seus discursos em relação a figura feminina. A cerveja no Brasil, muitas vezes aparece associada as mulheres, tais propagandas têm como objetivo principal atingir o público masculino. Nas propagandas analisadas, as mulheres aparecem estereotipadas, vistas somente como símbolo sexual, provocando além do apelo ao consumo, desejos através dos sentidos, pois aparecem desnudas e provocantes, despertando assim a libido no público alvo. Os anúncios publicitários fazem parte do cotidiano das pessoas, são utilizados para divertir, comunicar e interagir no meio em que são expostos, por isso a grande empreitada dos publicitários é encontrar meios de despertar interesse por sua marca, tudo se resume em uma luta pela atenção do consumidor.Palavras-chave: letras; Análise do Discurso; mulher; propagandas de cerveja.

    Full Text Available As autoras propõem a utilização de lentes de contato filtrantes coloridas para melhora da discriminação de cores e do ofuscamento, em portadores de discromatopsia, na impossibilidade de montagem de filtros coloridos em óculos. Foram adaptadas lentes de contato filtrantes coloridas em dois portadores de discromatopsias, um com deutanopia e outro com acromatopsia. No primeiro, adaptou-se lente rígida filtrante, de polimetilmetacrilato (PMMA, vermelha, no olho não dominante, com o objetivo de melhorar a discriminação de cores. No segundo, colocou-se lente filtrante gelatinosa, de uso diário, de coloração marrom escuro com pupila âmbar, visando melhorar o ofuscamento. No primeiro caso, o paciente manteve inalterada a acuidade visual e também o contraste, porém demonstrou melhora na discriminação das cores ao teste de PV-16. No segundo caso, houve melhora subjetiva acentuada do ofuscamento tanto em ambiente interno, como externo. A acuidade visual e a visão de cores permaneceram sem alterações. Os achados sugerem a possibilidade de contarmos com as lentes de contato filtrantes coloridas como importante auxílio para a melhora na discriminação de cores e ofuscamento, nas discromatopsias.

    Homeless female ex-offenders (homeless female offenders) exiting jail and prison are at a critical juncture during reentry and transitioning into the community setting. The purpose of the study was to compare the effect of a dialectical behavioral therapy-case management (DBT-CM) program with a health promotion (HP) program on achieving drug and alcohol abstinence among female parolees/probationers residing in the community. We conducted a multicenter parallel randomized controlled trial with 130 female parolees/probationers (aged 19-64 years) residing in the community randomly assigned to either DBT-CM (n = 65) or HP (n = 65). The trial was conducted in four community-based partner sites in Los Angeles and Pomona, California, from February 2015 to November 2016. Treatment assignment was carried out using a computer-based urn randomization program. The primary outcome was drug and alcohol use abstinence at 6-month follow up. Analysis was based on data from 116 participants with complete outcome data. Multivariable logistic regression revealed that the DBT-CM program remained an independent positive predictor of decrease in drug use among the DBT-CM participants at 6 months (p = .01) as compared with the HP program participants. Being non-White (p < .05) and having higher depressive symptom scores (p < .05) were associated with lower odds of drug use abstinence (i.e., increased the odds of drug use) at 6 months. DBT-CM increased drug and alcohol abstinence at 6-month follow-up, compared to an HP program.

    Full Text Available Background The results of numerous studies indicate strong associations of personality with the occurrence, and also with the treatment, of alcohol dependence. However, there is no agreement regarding the role of particular dimensions of temperament and character in the course of, and for the results of, alcohol rehabilitation therapy. The objective of the present research was to investigate the relationships between the dimensions of temperament and character as they are presented by Robert Cloninger and motivation for maintaining abstinence in the case of male alcohol-dependent individuals concluding the therapy. Participants and procedure Eighty-nine male alcohol-dependent individuals, concluding alcohol rehabilitation therapy in an outpatient setting, were studied. The following research tools were applied: the Temperament and Character Inventory (TCI of R. Clo­ninger in the Polish adaptation of E. Hornowska (2003, and the Motivation for Maintaining Abstinence Inventory, the author of which is M. Ziółkowski. Results Two clusters, differing in the aspect of motivation for maintaining abstinence after the conclusion of the treatment, were distinguished: of individuals manifesting weaker motivation (n = 39 and those manifesting stronger motivation (n = 50. The patients with stronger motivation manifested the following major features: a lower level of harm avoidance, a higher level of reward dependence, and a higher level of cooperativeness. Conclusions Personality as it is presented by Cloninger manifests connections with motivation for maintaining abstinence. The research confirms the need for diagnosing addicted patients in the scope of temperament and character traits.

    Discussion: “Central Paper on Temperance in the Grand Duchy of Poznań”, whose first issue was released in 1843 and in 1844 was continued as “Herald of Temperance in the Grand Duchy of Poznań”, was meant to popularise coping with alcohol abuse in society. The paper initiated the editorial series of abstinence periodicals available in the Polish language in the 19th century.

    The abnormal cognitive processing of drug cues is a core characteristic of drug dependence. Previous research has suggested that the late positive potential (LPP) of heroin users is increased by heroin-related stimuli because of the attention-grabbing nature of such stimuli. The present research used a modified emotional Stroop (eStroop) task to examine whether there was an early posterior negativity (EPN) modulation to heroin cues compared with emotional or neutral stimuli in heroin dependent subjects. Fifteen former heroin users and 15 matched controls performed the eStroop task, which was composed of positive, negative, heroin-related, and neutral pictures with superimposed color squares. Participants responded to the color of the square and not to the picture while behavioral data and event-related potentials were recorded. There were no significant differences of EPN amplitudes to emotional and neutral stimuli between heroin users and controls. However, heroin users displayed increased EPN modulation for heroin cues, whereas this modulation was absent in controls. Drug-related cues acquire motivational salience and automatically capture the attention of heroin users at early processing stages, even when engaged in a non-drug-related task. The EPN to heroin cues could represent a novel electrophysiological index with clinical implications for selecting abstinent drug users who are at increased risk of relapse or to evaluate treatment interventions.

    Full Text Available Treatment with acamprosate is a valid tool to complement psychotherapy as it does not cause addiction, abuse or withdrawal of its suspension and does not interfere with other medications that patients often alcoholics must take. To evaluate the effectiveness, our study evaluated the effects of Acamprosate compared to γ-hydroxybutyrate in clinical-physiological and social health in a way indicator of a possible therapeutic success in terms of abstinence from alcohol and social reintegration. A total of 36 patients were observed, of which 5, 4 men and 1 woman at the Drug Addiction Service (Servizio Tossicodipendenze, Ser.T Alcamo, and 31, 21 men and 10 women at the Ser.T of Palermo. As regards the craving, during the period of treatment with acamprosate, there has been a change, in the sense of reduction, of craving for alcohol: if before therapy was in 68% of cases, medium-high, it becomes after 3-4 months of therapy in low-nil in 89% of patients observed. It has been recorded that, after 3-4 months after receiving acamprosate, the clinical picture of the patient is greatly improved by referring to biological markers. In particular, the strong point seems to be the ability for the user to experience a new sense of normalcy and to remove the desire for significant periods of alcohol.

    Dysregulation of hedonic processing, in which seeking of drug reward becomes more desirable than seeking natural rewards, like food, sex, and novelty, is a consequence of chronic drug exposure and potentially leads to escalating drug usage and addiction. Here, we investigated the effects of chronic cocaine treatment (10 days of escalating doses of cocaine, 10-30 mg/kg) and multiple forced abstinence periods (2, 3 or 5 weeks) on the acute rewarding properties of either cocaine (10 mg/kg) or novel-objects using the conditioned place preference procedure. Following all cocaine withdrawal periods, cocaine preference was significantly elevated while novel object preference was abolished compared to saline-treated rats. At the earliest withdrawal period, these behavioral changes were accompanied by elevations in FosB-like immunoreactive staining in the basolateral amygdala (BLA) and nucleus accumbens shell (NAc-Sh) and core (NAc-C). FosB staining in all three brain areas correlated positively with cocaine preference, but negatively with novelty preference. After 5 weeks of withdrawal, FosB staining was only elevated in the NAc-Sh and again correlated positively with elevated cocaine preference but negatively with decreased novelty preference. These data indicate that alterations in the expression of FosB-like transcription factors in the NAc can predict the dysregulation of hedonic processing that occurs during protracted withdrawal from cocaine.

    Alcohol use is considered to be one of the major factors contributing to global health burden as well as social and economic harm. Only about 16% of alcohol dependent individuals enter addiction treatment programs in Poland, with only a few more in Western Europe. The aim of the paper was to present two main treatment strategies of alcohol dependence: total abstinence and harm reduction. The advantages and disadvantages of both treatment goals are presented, pointing to a possibility of treating them as complementary strategies. A need to choose a proper, personalised patient-oriented aim of a treatment program is emphasised, with an option to revise the objective during long-term therapy. The paper describes implications from investigating the problem of alcohol dependence from a population health perspective. The surprisingly high amount of individuals remitting spontaneously from alcohol dependence without treatment is also discussed, and a possible bias resulting from analysing data on alcoholic subjects coming only from addiction centres, not from general population is taken into consideration. In the second part of the paper, American as well as British alcohol treatment guidelines are presented.

    Hope is commonly divided into two constructs: agency, defined as goal-directed energy, and pathways, defined as the ability to create paths to a goal. To date, only two studies have examined the utility of hope in substance abuse recovery, and the present investigation buildings on this small literature by assessing hope beliefs within a larger and more diverse sample of adults in recovery. This study examined how two hope constructs of agency and pathways related to substance use abstinence among 90 new residents of communal-living recovery homes (i.e., Oxford Houses) who completed two waves of data assessment. Results indicated that agency scores significantly predicted alcohol use at Wave 1 but pathway scores failed to predict drug or alcohol use at this time point. Additionally, agency and pathway scores predicted drug (but not alcohol use) at an 8-month follow-up assessment. These findings indicated that participants’ hope may be linked to substance use at later stages of recovery. In addition, these results suggested a stronger relationship between hope and drug as opposed to alcohol use at this time point. Implications for substance abuse recovery are discussed.

    Full Text Available The success of any type of sexual education programme depends on the knowledge and preparedness for practice by adolescents. A recent study has found that an ‘abstinence-only’ sexual education programme is effective in reducing sexual activity among adolescents. Knowledge of abstinence-only sexual education and preparedness for practice as an effective tool for promotion of sexual health among Nigerian secondary school adolescents was studied. An analytic descriptive survey design was used for the study. The research population comprised of all public secondary schools in three southern geopolitical zones of the Niger Delta Region of Nigeria. A multistage sampling technique was used to select 2020 senior secondary school (SS1-SS3 students as sample for the study. A partially self-designed and partially adapted questionnaire from an 'abstinence-only versus comprehensive sex education' debate, from debatepedia (http://wiki.idebate.org/, entitled 'Questionnaire on Nigerian Secondary School Adolescents’ Perspective on Abstinence-Only Sexual Education (QNSSAPAOSE' was used in eliciting information from respondents. Hypotheses were formulated and tested. Frequency counts, percentage and Pearson Product Moment Correlation were used in analysing data. A greater proportion of secondary school adolescents in this study lacked knowledge of sexual education. About 80% of the respondents could not define sexual education. The general perspective on abstinence-only sexual education was negative, as revealed by the larger number of respondents who demonstrated unwillingness to practice abstinence-only sexual education. Specifically, of those who responded in favour of abstinence-only sexual education, the youngest group of adolescents (11-13 years and the male respondents were more likely to accept this type of education than the other groups. Poor knowledge of sexual education could be responsible for unwillingness to practice abstinence-only sexual

    Intact cognitive and emotional functioning is vital for the long-term success of addiction treatment strategies. Accumulating evidence suggests an association between chronic marijuana use and lasting alterations in cognitive brain function. Despite initial evidence for altered emotion processing in dependent marijuana users after short abstinence periods, adaptations in the domain of emotion processing after longer abstinence remain to be determined. Using task-based and resting state fMRI, the present study investigated emotion processing in 19 dependent marijuana users and 18 matched non-using controls after an abstinence period of > 28 days. Relative to the control subjects, negative emotional stimuli elicited increased medial orbitofrontal cortex (mOFC) activity and stronger mOFC-dorsal striatal and mOFC-amygdala functional coupling in dependent marijuana users (p < 0.022, FWE-corrected). Furthermore, mOFC-dorsal striatal functional connectivity was increased at rest in marijuana users (p < 0.03, FWE-corrected). Yet, processing of positive stimuli and subjective ratings of valence and arousal were comparable in both groups. Together, the present findings provide the first evidence for persisting emotion processing alterations in dependent marijuana users. Alterations might reflect long-term neural adaptations as a consequence of chronic marijuana use or predisposing risk factors for the development of marijuana dependence.

  6. Synapse density and dendritic complexity are reduced in the prefrontal cortex following seven days of forced abstinence from cocaine self-administration.

    Khampaseuth Rasakham

    Full Text Available Chronic cocaine exposure in both human addicts and in rodent models of addiction reduces prefrontal cortical activity, which subsequently dysregulates reward processing and higher order executive function. The net effect of this impaired gating of behavior is enhanced vulnerability to relapse. Previously we have shown that cocaine-induced increases in brain-derived neurotrophic factor (BDNF expression in the medial prefrontal cortex (PFC is a neuroadaptive mechanism that blunts the reinforcing efficacy of cocaine. As BDNF is known to affect neuronal survival and synaptic plasticity, we tested the hypothesis that abstinence from cocaine self-administration would lead to alterations in neuronal morphology and synaptic density in the PFC. Using a novel technique, array tomography and Golgi staining, morphological changes in the rat PFC were analyzed following 14 days of cocaine self-administration and 7 days of forced abstinence. Our results indicate that overall dendritic branching and total synaptic density are significantly reduced in the rat PFC. In contrast, the density of thin dendritic spines are significantly increased on layer V pyramidal neurons of the PFC. These findings indicate that dynamic structural changes occur during cocaine abstinence that may contribute to the observed hypo-activity of the PFC in cocaine-addicted individuals.

    Crack cocaine dependence has become a severe public health problem in Brazil, and current psychosocial approaches to this problem have shown little or no effectiveness. Although contingency management is among the most effective behavioral treatments for substance use disorders, it has never been applied in the treatment of crack cocaine-dependent individuals in Brazil. The aim of this study was to evaluate the efficacy of incorporating contingency management into standard outpatient treatment for crack cocaine dependence, as well as the impact that doing so has on treatment attendance, retention in treatment, maintenance of abstinence, and the frequency of substance use. We evaluated 65 treatment-seeking, crack cocaine-dependent individuals, randomized to receive 12 weeks of standard treatment plus contingency management (STCM; n = 33) or 12 weeks of standard treatment alone (STA; n = 32). Those in the STCM group received monetary incentives for being abstinent, earning up to US$235.50 if they remained abstinent throughout the entire treatment period. The STCM group participants attended a mean of 19.5 (SD = 14.9) treatment sessions, compared with 3.7 (SD = 5.9) for the STA group participants (p negative samples for crack cocaine, delta-9-tetrahydrocannabinol, and alcohol (p management showed efficacy in a sample of Brazilian crack cocaine users. The intervention holds promise for broader application in international settings. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  8. Pfeiffer syndrome

    Full Text Available Abstract Pfeiffer syndrome is a rare autosomal dominantly inherited disorder that associates craniosynostosis, broad and deviated thumbs and big toes, and partial syndactyly on hands and feet. Hydrocephaly may be found occasionally, along with severe ocular proptosis, ankylosed elbows, abnormal viscera, and slow development. Based on the severity of the phenotype, Pfeiffer syndrome is divided into three clinical subtypes. Type 1 "classic" Pfeiffer syndrome involves individuals with mild manifestations including brachycephaly, midface hypoplasia and finger and toe abnormalities; it is associated with normal intelligence and generally good outcome. Type 2 consists of cloverleaf skull, extreme proptosis, finger and toe abnormalities, elbow ankylosis or synostosis, developmental delay and neurological complications. Type 3 is similar to type 2 but without a cloverleaf skull. Clinical overlap between the three types may occur. Pfeiffer syndrome affects about 1 in 100,000 individuals. The disorder can be caused by mutations in the fibroblast growth factor receptor genes FGFR-1 or FGFR-2. Pfeiffer syndrome can be diagnosed prenatally by sonography showing craniosynostosis, hypertelorism with proptosis, and broad thumb, or molecularly if it concerns a recurrence and the causative mutation was found. Molecular genetic testing is important to confirm the diagnosis. Management includes multiple-staged surgery of craniosynostosis. Midfacial surgery is performed to reduce the exophthalmos and the midfacial hypoplasia.

    The compartment syndrome is defined as a condition in which high pressure within a closed fascial space (muscle compartment) reduces capillary blood perfusion below the level necessary for tissue viability'. This condition occurs in acute and chronic (exertional) forms, and may be secondary to a variety of causes. The end-result of an extended period of elevated intramuscular pressure may be the development of irreversible tissue injury and Volkmann's contracture. The goal of treatment of the compartment syndrome is the reduction of intracompartmental pressure thus facilitating reperfusion of ischaemic tissue and this goal may be achieved by decompressive fasciotomy. Controversy exists regarding the critical pressure-time thresholds for surgical decompression and the optimal diagnostic methods of measuring intracompartmental pressures. This paper will update and review some current knowledge regarding the pathophysiology, aetiology, diagnosis, and treatment of the acute compartment syndrome.

    Full Text Available Dressler Syndrome (DS is a febrile illness secondary to an inflammatory reaction involving the pleura and pericardium. It is more common in patients who have undergone surgery that involves opening the pericardium. However, DS has also been described following myocardial infarction and as an unusual complication after percutaneous procedures such as coronary stent implantation, after implantation of epicardial pacemaker leads and transvenous pacemaker leads, and following blunt trauma, stab wounds, and heart puncture. Pericardial effusions often accompany the syndrome and may develop into early or late postoperative cardiac tamponade and even recurrent cardiac tamponade. The syndrome is also characterized by pericardial or pleuritic pain, pleural effusions, pneumonitis, and abnormal ECG and radiography findings.

    Full Text Available In 1992, Brugada syndrom was introduced as a new clinical entity linking typical but variable ST segment changes in the right precordial leads to an increased vulnerability for lethal ventricular arrhythmias. The diagnosis of Brugada syndrome is based on clinical and electrocardiographic features. Recent studies illustrate the dynamic character of these ECG patterns. Whenever a large number of baseline ECGs was available during a follow-up, the diagnostic pattern could be documented only in approximately 25% of the tracings. Because the presence of the spontaneous coved type I ECG pattern is thought to be a useful predictor of future arrhythmic events in asymptomatic patients, these findings are of great clinical importance. ICD implantation is an option for the patients with Brugada syndrome and ventricular tachycardia or fibrillation. Extensive research is ongoing to find alternative pharmacological options for these patients, especially for patients in whom ICD implantation is contraindicated for various reasons.

    2014-01-01

    Full Text Available Introduction: Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. Objective: To describe a case of Eagle's syndrome. Case Report: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. Final Comments: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical.

    Eagle syndrome occurs due to elongation of the styloid process or calcification of the stylohyoid ligament, which then may produce a pain sensation due the pressure exerted on various structures in the head and neck. When suspected, imaging helps in identifying the abnormally elongated styloid process or the calcified ligament. In recent years, three-dimensional CT (3DCT) has proved to be valuable in these cases. We report the case of a 62-year-old man with this syndrome in whom imaging with 3DCT conclusively established the diagnosis

    Lemierre\\'s syndrome is a rare disease that results in an oropharyngeal infection, which precipitates an internal jugular vein thrombosis and metastatic infection. Fusobacterium necrophorum is an anaerobic Gram-negative bacillus and has been identified as the causative agent. We describe the case of a young girl whose presentation and diagnosis were confounded by a history of valvular heart disease. Infection of heart valves can produce many of the signs and symptoms associated with Lemierre\\'s syndrome. We describe the diagnosis, investigation and optimal management of this rare disorder.
