Sialorrhea in children with cerebral palsy (CP) results in aspiration, decreased social integration, and poor quality of life. Management options include transdermal anticholinergics such as the scopolamine patch. A controlled clinical trial has proven botulinum toxin (BTX) injections into the salivary glands are an effective alternative to transdermal anticholinergics with a safer side effect profile. Multiple studies of the injections in diverse populations demonstrate reduction in saliva production with improvement in quality of life and decrease in hospitalization-associated costs. The authors describe a 15-year-old boy with spastic quadriplegic CP who developed emesis, nausea, and lethargy 1 day after the first injection of botulinum toxin A (BTX-A) to his salivary glands for sialorrhea management. The authors ascribed his symptoms to scopolamine withdrawal. Given the lack of exposure in the medical literature, there is minimal awareness of the withdrawal syndrome from transdermal scopolamine in children with or without CP, resulting in delayed diagnosis and potential complications. Treatment of the withdrawal syndrome has been successful with meclizine though safety and efficacy has not been established in children younger than 12 despite frequent clinical and over-the-counter use. Prompt diagnosis of the transdermal scopolamine withdrawal syndrome can result in quicker treatment and a shorter hospital stay.

The objectives of the study were (1) to assess prevalence of social withdrawal behaviour in infants aged 12 months included in the French Perinatal Risk Factor Study Eden; (2) To study the correlation between relational withdrawal and several perinatal and parental factors assessed in the EDEN study. A longitudinal study using the ADBB scale was conducted within the Eden Cohort in the year 2008. 1,586 infants were included in the study. Fourteen percent of the children who had an ADBB assessment had a score at 5 and over on the ADBB, a scale designed to assess social withdrawal behaviour at age 0-24 months. Social withdrawal at 12 months was associated with low birth weight, low gestational age and with intra uterine growth retardation. Social withdrawal was independently associated with several maternal and paternal risk factors. The level of social withdrawal behaviour increased with a score of maternal difficulties. This study on a large longitudinally followed volunteer sample demonstrate a clear association of social withdrawal behaviour at age one with low birth weight and preterm birth, possibly mediated by parental vulnerabilities. Social withdrawal behaviour seems to be an important alarm signal to detect early on particularly in premature and small for date babies. © Springer-Verlag 2012

Review of adjunctive dexmedetomidine in the management of severe acute alcohol withdrawal syndrome.

PubMed

Wong, Adrian; Smithburger, Pamela L; Kane-Gill, Sandra L

2015-01-01

The primary management of alcohol withdrawal involves the administration of a γ-aminobutyric acid agonist, such as benzodiazepines, for management of symptoms and to prevent further progression to seizure or delirium tremens. Despite escalating doses of benzodiazepines, published literature indicates that some patient's alcohol withdrawal syndrome symptoms do not respond, and that the use of adjunctive agents may be beneficial in these patients. Dexmedetomidine, an α2-agonist, serves as a potential adjunctive agent through management of associated autonomic symptoms. Understanding of recent literature evaluating its use is necessary for appropriate selection. To review available literature supporting the use of adjunctive dexmedetomidine for management of severe alcohol withdrawal syndrome. A total of 13 published articles evaluating the efficacy and safety of dexmedetomidine as an adjunctive agent for the treatment of alcohol withdrawal in adult patients were identified from a MEDLINE search using the key words alcohol withdrawal, delirium tremens and dexmedetomidine. Evaluation of the literature indicates that dexmedetomidine is associated with a decrease in short-term benzodiazepine requirements after initiation, and improvement in hemodynamic parameters in relation to the adrenergic drive present in alcohol withdrawal. The use of dexmedetomidine in the management of severe alcohol withdrawal should be considered as an adjunctive agent. Dexmedetomidine appears to be well tolerated, with an expected decrease in blood pressure and heart rate. Seizures have occurred in patients with alcohol withdrawal despite the use of dexmedetomidine, with and without benzodiazepines, due to lack of γ-aminobutyric acid agonist administration.

To analyse the influence of epidemiological and sociodemographic factors in complicated alcohol withdrawal syndrome (AWS). A multicentre, observational prospective study was conducted on consecutively added patients with AWS hospitalised in internal medicine departments. We recorded sociodemographic, epidemiological, clinical and progression data. Complicated AWS was defined as that which progressed with seizures or delirium tremens. We studied 228 episodes of AWS in 219 patients. The mean age was 54.5 years (SD, 11.5), and 90.8% were men. AWS was the cause for hospitalisation in 39.9% of the patients. Some 27.1% of the cases presented seizures, and 32.4% presented delirium tremens. The daily quantity of alcohol ingested was 17.8 standard drink units (SD, 21.4), with 16.6 years of dependence (SD, 11.3). The pattern of alcohol abuse was regular in 82.8% of the patients. Some 38.4% of the patients were married or had a partner, and 45.6% had children. Some 72.7% of the patients were unemployed or retired. Some 68.5% had only completed primary studies. Some 4.8% consumed cannabis, 5.2% consumed cocaine and 3% consumed opioids. The independent variables related to complicated AWS were consumption of a drug other than alcohol (OR, 5.3; 95% CI 1.5-18.7), low education level (OR, 3.4; 95% CI 1.6-7.3) and hospitalisation for AWS (OR, 2.9; 95% CI 1.5-5.6). The model's receiver operating characteristic area was 0.718 (95% CI 0.643-0.793). Concomitant drug abuse and a low educational level could help identify patients at risk of complicated AWS.

To observe the efficacy difference of electroacupuncture and auricular acupuncture in the treatment of methamphetamine withdrawal syndrome. Ninety male patients of methamphetamine addiction were randomized into an electroacupuncture group, an auricular acupuncture group and a control group, 30 cases in each one. In the electroacupuncture group, Neiguan (PC 6), Shenmen (HT 7), Zusanli (ST 36), Sanyinjiao (SP 6), Jiaji (EX-B 2) at T5 and L2 were selected bilaterally. In the auricular acupuncture group, jiaogan (AH(6a)), shenmen (TF4), fei (CO14) and gan (CO12) were selected unilaterally. The treatment was given 3 times a week, totally 12 treatments were required. In the control group, no any intervention was applied. Separately, before treatment and after 1, 2, 3 and 4 weeks treatment, the scores of methamphetamine withdrawal syndrome, Hamilton anxiety scale and Hamilton depression scale were observed in each group. The total score of methamphetamine withdrawal syndrome, anxiety score and depression score were obviously reduced in 2, 3 and 4 weeks of treatment as compared with those before treatment in the electroacupuncture group and the auricular acupuncture group (all P < 0.05), and showed a trend of gradual decline as the extension of treatment. In 1,2,3,4 weeks of treatment, the total score of withdrawal syndrome, anxiety score and depression score in the electroacupuncture group and auricular acupuncture group were lower significantly than those in the control group (all P < 0.05), in which, the total score of withdrawal syndrome in the electroacupuncture group was lower significantly than that in the auricular acupuncture group in the 4th week of treatment (3.69 +/- 2.446 vs 5.73 +/- 3.169, P < 0.05); the anxiety scores were lower significantly than those in the auricular acupuncture group in 3 and 4 weeks of treatment (8.19 +/- 4.57 vs 9.65 +/- 4.24, 5.27 +/- 2.89 vs 7.38 +/- 3.10, both P < 0.05); the depression scores were lower significantly than those in

Alcoholic patients suffer from harmful allostatic neuroplastic changes in the brain causing an acute withdrawal syndrome upon cessation of drinking followed by a protracted abstinence syndrome and an increased risk of relapse to heavy drinking. Benzodiazepines have long been the treatment of choice for detoxifying patients and managing alcohol withdrawal syndrome (AWS). Non-benzodiazepine anticonvulsants (NBACs) are increasingly being used both for alcohol withdrawal management and for ongoing outpatient treatment of alcohol dependence, with the goal of either abstinence or harm reduction. This expert narrative review summarizes the scientific basis and clinical evidence supporting the use of NBACs in treating AWS and for reducing harmful drinking patterns. There is less evidence in support of NBAC therapy for AWS, with few placebo-controlled trials. Carbamazepine and gabapentin appear to be the most promising adjunctive treatments for AWS, and they may be useful as monotherapy in select cases, especially in outpatient settings and for the treatment of mild-to-moderate low-risk patients with the AWS. The body of evidence supporting the use of the NBACs for reducing harmful drinking in the outpatient setting is stronger. Topiramate appears to have a robust effect on reducing harmful drinking in alcoholics. Gabapentin is a potentially efficacious treatment for reducing the risk of relapse to harmful drinking patterns in outpatient management of alcoholism. Gabapentin's ease of use, rapid titration, good tolerability, and efficacy in both the withdrawal and chronic phases of treatment make it particularly appealing. In summary, several NBACs appear to be beneficial in treating AWS and alcohol use disorders.

Gamma-hydroxybutyric acid (GHB) withdrawal is a complex syndrome which can be potentially life-threatening. Additionally, GHB-dependent patients frequently report co-occurring substance use of other psychoactive drugs. We assessed the add-on effect of co-use on GHB withdrawal symptoms. We conducted an open-label, pretest-posttest design study with 95 patients selected from 229 inpatients admitted for detoxification, who were divided into GHB only (GO, n = 40), GHB plus sedatives (GSE, n = 38), and GHB plus stimulants (GST, n = 17) groups. GHB withdrawal was evaluated by means of the Subjective Withdrawal Scale. Co-use add-on effects on the severity of withdrawal symptoms were evaluated 2.5 hours after the last illicit GHB self-administration (T1) when withdrawal was expected and 2.5 hours later, after administration of a very low dose of pharmaceutical GHB (T2). The GO group reported high scores of psychomotor retardation symptoms at both T1 and T2, and also high cravings, agitation, and restlessness at T1, and anxiety at T2. The GSE group reported the highest score in psycho-autonomic distress symptoms at both T1 and T2, whereas the GST group reported the highest score in psycho-motor stress factor at T2. There was no significant difference in withdrawal intensity in all symptom clusters between T1 and T2 for both GSE and GO groups. However, after 5 hours, the GST group reported significant decreases in intensity for all symptoms except for psycho-motor stress. At T1, GST and GSE groups reported more muscle twitches than the GO group as a significant add-on effect to the GHB withdrawal. At T2, the GST group experienced more agitation (P = 0.009), restlessness (P = 0.001), and rapid pulse (P = 0.034) than the GO group. Co-use, especially of stimulants, caused an add-on effect on the GHB withdrawal symptoms within the first 5 hours.

Nalmefene, a long-acting µ-opioid antagonist approved to treat alcohol use disorder, is occasionally mistakenly prescribed to opiate-dependent or opioid-treated patients. We review recent literature on drug-drug interactions between nalmefene and opioids that lead to precipitated opioid withdrawal, and focus on its management and planning for care at discharge. Areas covered: This article provides a brief and comprehensive review of management of precipitated opioid withdrawal syndrome when nalmefene is associated with an opioid, whether misused or legally prescribed. Expert opinion: When treating an opiate-dependent patient with co-occurring alcohol use disorder, both conditions need to be a focus of clinical attention. New drugs for alcohol use disorder have been approved, but must be given cautiously and with a full understanding of their potential drug-drug interactions with opioid medications. Opiate-dependent patients should be intensively monitored for risk factors of alcohol use disorder and should be continuously motivated for treatment maintenance. When nalmefene is administered to opiate-dependent patients, acute opioid withdrawal syndrome may occur. Management of precipitated acute opioid withdrawal may include short or long-acting µ-opioid agonists during hospitalization, in addition to supportive treatment. The best management of polydrug abusers is based on a multidisciplinary approach, which should be pursued and improved through continuing medical education.

There have been many reports of monoamine oxidase (MAO) inhibition by non-nicotine ingredients in tobacco smoke, persisting for days after smoking cessation. This study determined the effect of inhibiting MAO and its isoforms on nicotine withdrawal syndrome. Rats were rendered nicotine-dependent by seven days of subcutaneous (s.c.) 9 mg/kg/day infusion of nicotine bitartrate. Twenty-two hours after termination of infusion, they were observed over 20 min for somatically expressed nicotine withdrawal signs. Three hours before observation, rats were injected intraperitoneally (i.p.) with 4 mg/kg each of the MAO A antagonist clorgyline and the MAO B antagonist deprenyl, or with saline alone. A similar experiment was performed with non-dependent, saline-infused rats. Another experiment compared nicotine-dependent rats that received injections of either saline or 4 mg/kg clorgyline alone. A further experiment compared rats receiving either saline or 4 mg/kg deprenyl alone. Combined treatment with both MAO inhibitors markedly and significantly exacerbated somatically expressed nicotine withdrawal signs in nicotine infused rats, while having no significant effects in saline-infused rats. Rats injected s.c. with 4 mg/kg clorgyline alone had significantly more withdrawal signs than saline-injected rats, while deprenyl-injected rats had significantly fewer signs than saline controls. Assays confirmed that clorgyline thoroughly reduced MAO A enzymatic activity and deprenyl thoroughly reduced MAO B activity. The results suggest that inhibition of MAO A may contribute to the intensity of withdrawal syndrome in smoking cessation. © 2013 Elsevier Inc. All rights reserved.

Cannabis sativa withdrawal syndrome is characterized mainly by psychological symptoms. By using computational tools, the aim of this study was to propose drug candidates for treating withdrawal syndrome based on the natural ligands of the cannabinoid type 1 receptor (CB1). One compound in particular, 2-n-butyl-5-n-pentylbenzene-1,3-diol (ZINC1730183, also known as stemphol), showed positive predictions as a human CB1 ligand and for facile synthetic accessibility. Therefore, ZINC1730183 is a favorable candidate scaffold for further research into pharmacotherapeutic alternatives to treat C. sativa withdrawal syndrome. © 2017 Wiley-VCH Verlag GmbH & Co.

Epidemiologic studies suggest reduced cardiovascular disease (CVD) events with moderate alcohol consumption. However, heavy and binge drinking may be associated with higher CVD risk. Utilizing the Nationwide Inpatient Sample, we studied the association between a troublesome alcohol history (TAH), defined as those with diagnoses of both chronic alcohol syndrome and acute withdrawal history and CVD events. Patients >18 years with diagnoses of both chronic alcohol syndrome and acute withdrawal using the International Classification of Diseases-Ninth Edition-Clinical Modification (ICD-9-CM) codes 303.9 and 291.81, were identified in the Nationwide Inpatient Sample 2009-2010 database. Demographics, including age and sex, as well as CVD event rates were collected. Patients with TAH were more likely to be male, with a smoking history and have hypertension, with less diabetes, hyperlipidemia and obesity. After multimodal adjusted regression analysis, odds of coronary artery disease, acute coronary syndrome, in-hospital death and heart failure were significantly lower in patients with TAH when compared to the general discharge patient population. Utilizing a large inpatient database, patients with TAH had a significantly lower prevalence of CVD events, even after adjusting for demographic and traditional risk factors, despite higher tobacco use and male sex predominance, when compared to the general patient population.

Background: Patients with obstructive sleep apnea/hypopnea syndrome (OSAHS), even those generally compliant with CPAP therapy, often intermittently discontinue CPAP. Study Objective: Examine the impact of CPAP withdrawal on sleep, sleep disordered breathing (SDB), and daytime function in subjects with varying severity of OSAHS. Patients and Interventions: Forty-two subjects (26M/16 F) with OSAHS (AHI4% = 45.2 ± 35.5/h pretreatment) on CPAP for 4 months were evaluated on the second night of CPAP withdrawal. Sleep architecture, SDB indices, and subjective/objective daytime function were assessed pretreatment, on CPAP therapy, and after CPAP withdrawal. Comparisons were made between pretreatment and CPAP withdrawal for the entire group, and for subgroups of mild/moderate (AHI4% < 30/h, n = 22) and severe (AHI4% > 30/h, n = 20) SDB. Results: Overall, and for mild/moderate subjects, SDB indices returned to pretreatment values on CPAP withdrawal but with fewer apneas and more hypopneas/RERAs. For severe SDB, the event frequency (AI, AHI4%, and RDI) was lower and O2 desaturation was improved on CPAP withdrawal. Across SDB severity, sleep architecture showed lower %REM (15.6% vs 12.9%, P = 0.009) on the CPAP withdrawal compared to pretreatment. Stanford Sleepiness Score, MSLT, and PVT measures were not significantly different between pretreatment and CPAP withdrawal. Conclusions: Over a wide range of SDB severity CPAP withdrawal results in recurrence of SDB, albeit with less severe O2 desaturation. Subjective/objective daytime function returned to pretreatment levels. Sleep architecture changes on CPAP withdrawal (acute SDB) may reflect reduced sleep pressure compared to pretreatment chronic SDB. Our data suggest detrimental effects of even brief withdrawal of CPAP in subjects with both mild and severe OSAHS. Citation: Young LR; Taxin ZH; Norman RG; Walsleben JA; Rapoport DM; Ayappa I.

Purpose To explore whether the ‘hikikomori’ syndrome (social withdrawal) described in Japan exists in other countries, and if so, how patients with the syndrome are diagnosed and treated. Methods Two hikikomori case vignettes were sent to psychiatrists in Australia, Bangladesh, India, Iran, Japan, Korea, Taiwan, Thailand and the USA. Participants rated the syndrome's prevalence in their country, etiology, diagnosis, suicide risk, and treatment. Results Out of 247 responses to the questionnaire (123 from Japan and 124 from other countries), 239 were enrolled in the analysis. Respondents’ felt the hikikomori syndrome is seen in all countries examined and especially in urban areas. Biopsychosocial, cultural, and environmental factors were all listed as probable causes of hikikomori, and differences among countries were not significant. Japanese psychiatrists suggested treatment in outpatient wards and some did not think that psychiatric treatment is necessary. Psychiatrists in other countries opted for more active treatment such as hospitalization. Conclusions Patients with the hikikomori syndrome are perceived as occurring across a variety of cultures by psychiatrists in multiple countries. Our results provide a rational basis for study of the existence and epidemiology of hikikomori in clinical or community populations in international settings. PMID:21706238

Recent literature on withdrawing antiepileptic drug therapy in patients who are seizure free on antiepileptic drugs is reviewed. The average recurrence risk across studies is 29% at 2 years. Factors such as age of onset, etiology of seizures, the electroencephalogram and the epileptic syndrome influence outcome. Factors that need to be considered by the clinician include not just the statistical risk of recurrence but also the consequences of a recurrence, which will be a function of age and sex.

Exploring Multitarget Interactions to Reduce Opiate Withdrawal Syndrome and Psychiatric Comorbidity

2013-01-01

Opioid addiction is often characterized as a chronic relapsing condition due to the severe somatic and behavioral signs, associated with depressive disorders, triggered by opiate withdrawal. Since prolonged abstinence remains a major challenge, our interest has been addressed to such objective. Exploring multitarget interactions, the present investigation suggests that 3 or its (S)-enantiomer and 4, endowed with effective α2C-AR agonism/α2A-AR antagonism/5-HT1A-R agonism, or 7 and 9–11 producing efficacious α2C-AR agonism/α2A-AR antagonism/I2–IBS interaction might represent novel multifunctional tools potentially useful for reducing withdrawal syndrome and associated depression. Such agents, lacking in sedative side effects due to their α2A-AR antagonism, might afford an improvement over current therapies with clonidine-like drugs. PMID:24900763

The relation between Bulimic symptoms and the social withdrawal syndrome during early adolescence.

Rotenberg, Ken J; Sangha, Rajvir

2015-12-01

The short-term longitudinal study tested the hypothesis that there was a prospective relation between the social withdrawal syndrome and Bulimic symptoms during early adolescence. Ninety-six adolescents (47 males, mean age=13 years - 10 months) completed standardized scales assessing Bulimic symptoms, trust beliefs in others and loneliness at Time 1/T1 and again 5 months later at Time 2/T2. Analyses showed that: (1) Bulimic symptoms were negatively correlated with trust beliefs, (2) Bulimic symptoms were positively correlated with loneliness, and (3) trust beliefs were negatively correlated with loneliness. The SEM and mediation analyses showed that trust beliefs at T1 were negatively and concurrently associated with Bulimic symptoms at T1 and longitudinally (and negatively) predicted changes in Bulimic symptoms. It was found that loneliness at T1 statistically mediated those concurrent and longitudinal relations. The findings yielded support for the conclusion that the social withdrawal syndrome, as assessed by low trust beliefs and resulting experiences of loneliness, contributes to Bulimia nervosa during early adolescence.

One hundred and thirty-seven undergraduates (81 females; mean age = 21 years-10 months) completed the Bulimic SEDS subscale and standardized measures of trust beliefs in close others (mother, father, and friend), disclosure to them, and loneliness. Structural Equation Modelling yielded: (1) a negative path between Bulimic Symptoms and trust beliefs, (2) a positive path between trust beliefs and disclosure, (3) a negative path between trust beliefs and loneliness, and (4) a negative path between disclosure and loneliness. As expected, trust beliefs statistically mediated the relations between Bulimic Symptoms and both disclosure and loneliness and disclosure statistically mediated the relation between trust beliefs and loneliness. The findings supported the conclusion that individuals with bulimia nervosa are prone to the social withdrawal syndrome comprising a coherent and integrated pattern of low trust beliefs in close others, low disclosure to close others, and high loneliness.

Treatment of alcohol withdrawal syndrome (AWS) with benzodiazepines is limited by risk of abuse, intoxication, respiratory problems, and liver toxicity. Alternatives such as carbamazepine and valproate may also have safety problems, such as hepatotoxicity or central nervous adverse effects. We therefore investigated the safety and efficacy of levetiracetam (LV), a newer antiepileptic with a potentially favorable adverse-effect profile, for the treatment of AWS. One hundred six patients were enrolled in a prospective, randomized, double-blind, multicenter, placebo-controlled trial. Levetiracetam was administered in a fixed dose schedule over 6 days. Diazepam was added when symptom triggered as rescue medication. Severity of the AWS was measured with the AWS and Clinical Institute Withdrawal Assessment Scale. Although tolerability and safety data were similar in the LV group when compared with placebo, the total daily and weekly dose of diazepam as rescue medication and the severity of alcohol withdrawal symptoms did not differ significantly between groups. Our data so far do not support an additional effect of LV on the reduction of alcohol withdrawal symptoms.

Many symptoms of alcohol withdrawal (AW) such as tachycardia or elevated blood pressure might be explained by increased peripheral and central adrenergic activity. In contrast to many neurochemical studies of sympathetic activation during AW, only very few studies investigated autonomic balance using neurophysiological methods. We investigated heart rate variability (HRV) and sympathetic skin response (SSR) in male patients suffering from mild AW syndrome (n = 20, no treatment required) and in patients with moderate to severe AW syndrome (n = 20, clomethiazole treatment) in the acute stage. Sympathovagal influence was quantified using measures of time and frequency domain of HRV as well as modern nonlinear parameters (compression entropy). Furthermore, we obtained latencies and amplitudes of SSR to quantify isolated sympathetic influence. Measures were obtained during the climax of withdrawal symptomatology before treatment, 1 day after climax, and shortly before discharge from hospital. Alcohol withdrawal scores were obtained and correlated to autonomic measures. Ambulatory blood pressure and AW scores revealed characteristic withdrawal symptoms in both patient groups. Apart from the nonlinear parameter compression entropy, Hc, measures of HRV revealed no sign of autonomic dysfunction in contrast to the significantly increased heart rates at the time of admission. Latencies and amplitudes of SSR did not indicate any increase of sympathetic activity. A negative correlation was found between Hc and mental withdrawal symptoms. We show here that classical measures for autonomic nervous system activity such as HRV and SSR are not suitable for describing the autonomic changes seen in acute AW, although a major role for the sympathetic nervous system has been proposed. This might be due to multiple dysregulation of metabolites in AWS or to subtle alcohol-induced damage to neuronal structures, issues that should be addressed in future studies.

The relation between obesity and Social Withdrawal Syndrome (SWS) was examined using the data gathered by Rotenberg, Bharathi, Davies, and Finch (2013). One hundred and 35 undergraduates (80 females; Mage=21years-10months) completed standardized scales that assessed the SWS (low emotional trust beliefs in close others, low disclosure to close others, and high loneliness). BMI was calculated from self-reported weight and height. As hypothesized, quadratic relations were found in which participants with BMI>30 (i.e., obese) demonstrated the SWS pattern of low emotional trust beliefs in close others, low disclosure to close others, and high loneliness. As further evidence, lower emotional trust in close others, lower disclosure to close others, and greater loneliness were found for obese participants (>30 BMI, n=27) than both normal weight (<25 BMI, n=67) and overweight participants (25 to 30 BMI, n=41). The findings confirmed the hypothesis that obesity was associated with the SWS. The findings suggested that the lack of trust in others by obese individuals contributes to their unwillingness to seek out help for health and psychosocial problems. Copyright © 2017 Elsevier Ltd.

Expectancies have been shown to play a role in the withdrawal syndrome of many drugs of addiction; however, no studies have examined the effects of expectancies across a broad range of caffeine withdrawal symptoms, including craving. The purpose of the current study was to use caffeine as a model to test the effect of expectancy on withdrawal symptoms, specifically whether the belief that one has ingested caffeine is sufficient to reduce caffeine withdrawal symptoms and cravings in abstinent coffee drinkers. We had 24-h abstinent regular coffee drinkers complete the Caffeine Withdrawal Symptom Questionnaire (CWSQ) before and after receiving decaffeinated coffee. One-half of the participants were led to believe the coffee was regular caffeinated coffee (the 'Told Caffeine' condition) and one-half were told that it was decaffeinated (the 'Told Decaf' condition). Participants in the Told Caffeine condition reported a significantly greater reduction in the factors of cravings, fatigue, lack of alertness and flu-like feelings of the CWSQ, than those in the Told Decaf condition. Our results indicated that the belief that one has consumed caffeine can affect caffeine withdrawal symptoms, especially cravings, even when no caffeine was consumed. © The Author(s) 2016.

Caffeine as a model drug of dependence: recent developments in understanding caffeine withdrawal, the caffeine dependence syndrome, and caffeine negative reinforcement.

PubMed

Griffiths, R R; Chausmer, A L

2000-11-01

Caffeine is an excellent model compound for understanding drugs of abuse/dependence. The results of self-administration and choice studies in humans clearly demonstrate the reinforcing effects of low and moderate doses of caffeine. Caffeine reinforcement has been demonstrated in about 45% of normal subjects with histories of moderate and heavy caffeine use. Recent studies provide compelling evidence that caffeine physical dependence potentiates the reinforcing effects of caffeine through the mechanism of withdrawal symptom avoidance. Tolerance to the subjective and sleep-disrupting effects of caffeine in humans has been demonstrated. Physical dependence as reflected in a withdrawal syndrome in humans has been repeatedly demonstrated in adults and recently demonstrated in children. Withdrawal severity is an increasing function of caffeine maintenance dose, with withdrawal occurring at doses as low as 100 mg per day. Increased cerebral blood flow may be the physiological mechanism for caffeine withdrawal headache. Case studies in adults and adolescents clearly demonstrate that some individuals meet DSM-IV diagnostic criteria for a substance dependence syndrome on caffeine, including feeling compelled to continue caffeine use despite desires and recommendations to the contrary. Survey data suggest that 9% to 30% percent of caffeine consumers may be caffeine dependent according to DSM-IV criteria.

Anticonvulsants are considered a second line option for bipolar disorder, it is known that the abrupt withdrawal is rarely related with demyelinated lesions of the splenium of the corpus callosum. Oxcarbazepine is used in bipolar disorder although it is not stated in the data sheet. We presented a case of a 50 years old woman with bipolar disorder who is treated with lithium and oxcarbazepine, she presented a manic episode and a confusional syndrome after she stopped taking the medication. The magnetic resonance showed a restricted diffusion area at the splenium of the corpus callosum and bifrontal hygromas that disappear two weeks later. The results of this study suggest that for a patient presenting with a mild encephalopathy and reversible splenial lesion, one should consider whether it is related to withdrawal of oxcarbazepine.

2015-01-01

Adolescents higher in temperamental withdrawal are at risk for anxiety and depressive symptoms; however, not all youth higher in withdrawal exhibit internalizing symptoms, suggesting that contextual factors may influence these relationships. We examined whether youth withdrawal moderates the relationships between neighborhood processes (crime, social cohesion) and internalizing symptoms and whether findings were consistent with diathesis-stress or differential susceptibility hypotheses. Participants were 775 adolescents (M=15.50 ± 0.56 years, 72% male, 76% White). Adolescents higher in withdrawal manifested higher internalizing symptoms in the context of lower neighborhood crime and lower neighborhood social cohesion than youth lower in withdrawal, supporting diathesis-stress. These findings elucidate neighborhood processes associated with internalizing symptoms, which can inform models of risk and resilience for these symptoms among children who differ in temperamental withdrawal.

We run Exploratory and Confirmatory Factor Analyses of the Minnesota Nicotine Withdrawal Scale (MNWS) and of the MNWS-Revised (MNWS-R). Psychometric properties were also explored. Adult Italian smokers, 366 in all, were assessed via the MNWS-R together with rating scales measuring cigarette dependence, alcohol use, anxiety sensitivity and negative affect at baseline and after 3 months. The MNWS showed good psychometric properties (α = 0.85; rtt = 0.59) and a unidimensional factor structure. The 2-factor model of MNWS-R had the best fit and the factors were labelled psychological symptoms (α = 0.86; rtt = 0.59) and associated somatic features (α = 0.64; rtt = 0.45). MNWS showed 1 factor; MNWS-R showed 2 relatively dependent factors. The results need to be replicated in smokers in withdrawal. © 2017 S. Karger AG, Basel.

Consequences of brain-derived neurotrophic factor withdrawal in CNS neurons and implications in disease

PubMed Central

Mariga, Abigail; Mitre, Mariela; Chao, Moses V.

2017-01-01

Growth factor withdrawal has been studied across different species and has been shown to have dramatic consequences on cell survival. In the nervous system, withdrawal of nerve growth factor (NGF) from sympathetic and sensory neurons results in substantial neuronal cell death, signifying a requirement for NGF for the survival of neurons in the peripheral nervous system (PNS). In contrast to the PNS, withdrawal of central nervous system (CNS) enriched brain-derived neurotrophic factor (BDNF) has little effect on cell survival but is indispensible for synaptic plasticity. Given that most early events in neuropsychiatric disorders are marked by a loss of synapses, lack of BDNF may thus be an important part of a cascade of events that leads to neuronal degeneration. Here we review reports on the effects of BDNF withdrawal on CNS neurons and discuss the relevance of the loss in disease. PMID:27015693

Passiflora incarnata L. (Passifloraceae) has been traditionally used for treatment of anxiety, insomnia, drug addiction, mild infections, and pain. The aim of this study was to investigate the effect of a commercial extract of P. incarnata in the analgesia induced by alcohol withdrawal syndrome in rats. In addition, brain-derived neurotrophic factor and interleukin-10 levels were evaluated in prefrontal cortex, brainstem, and hippocampus. Male adult rats received by oral gavage: (1: water group) water for 19 days, 1 day interval and water (8 days); (2: P. incarnata group) water for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days); (3: alcohol withdrawal group) alcohol for 19 days, 1 day interval and water (8 days); and (4: P. incarnata in alcohol withdrawal) alcohol for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days). The tail-flick and hot plate tests were used as nociceptive response measures. Confirming previous study of our group, it was showed that alcohol-treated groups presented an increase in the nociceptive thresholds after alcohol withdrawal, which was reverted by P. incarnata, measured by the hot plate test. Besides, alcohol treatment increased brain-derived neurotrophic factor and interleukin-10 levels in prefrontal cortex, which was not reverted by P. incarnata. Considering these results, the P. incarnata treatment might be a potential therapy in the alcohol withdrawal syndrome. Copyright © 2017 John Wiley & Sons, Ltd.

Refeeding syndrome is uncommon in alcoholics admitted to a hospital detoxification unit.

The refeeding syndrome is increasingly recognised. It is a serious change in electrolytes when nutrition is reintroduced to malnourished patients. Alcohol dependence is a risk factor for the refeeding syndrome. We report a prospective cohort study of 36 alcoholics hospitalised for withdrawal management. We found no evidence of refeeding syndrome in any patient after 3 days of hospitalisation, despite hypomagnesaemia, a risk factor for the refeeding syndrome being prevalent (44% of subjects). Low thiamine levels were infrequent affecting 3/29 (10%). We recommend that in alcoholics admitted for managed withdrawal, risk of refeeding syndrome appears to be low, and routine testing of repeat electrolytes appears unnecessary. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

Youth social withdrawal behavior (hikikomori): A systematic review of qualitative and quantitative studies.

Acute and/or severe social withdrawal behavior among youth was seen as a culture-bound psychiatric syndrome in Japan, but more youth social withdrawal cases in different countries have been discovered recently. However, due to the lack of a formal definition and diagnostic tool for youth social withdrawal, cross-cultural observational and intervention studies are limited. We aimed to consolidate existing knowledge in order to understand youth social withdrawal from diverse perspectives and suggest different interventions for different trajectories of youth social withdrawal. This review examined the current available scientific information on youth social withdrawal in the academic databases: ProQuest, ScienceDirect, Web of Science and PubMed. We included quantitative and qualitative studies of socially withdrawn youths published in English and academic peer-reviewed journals. We synthesized the information into the following categories: (1) definitions of youth social withdrawal, (2) developmental theories, (3) factors associated with youth social withdrawal and (4) interventions for socially withdrawn youths. Accordingly, there are diverse and controversial definitions for youth social withdrawal. Studies of youth social withdrawal are based on models that lead to quite different conclusions. Researchers with an attachment perspective view youth social withdrawal as a negative phenomenon, whereas those who adopt Erikson's developmental theory view it more positively as a process of seeking self-knowledge. Different interventions for socially withdrawn youths have been developed, mainly in Japan, but evidence-based practice is almost non-existent. We propose a theoretical framework that views youth social withdrawal as resulting from the interplay between psychological, social and behavioral factors. Future validation of the framework will help drive forward advances in theory and interventions for youth social withdrawal as an emerging issue in developed

Nabilone therapy for cannabis withdrawal presenting as protracted nausea and vomiting.

Lam, Philip W; Frost, David W

2014-09-22

Cannabis is one of the most commonly used recreational drugs worldwide. Psychoactive properties of the principal compound, δ-9-tetrahydrocannabinol include euphoria, a sense of relaxation and increased appetite. Chronic cannabis use has been associated with the development of a withdrawal syndrome on abrupt discontinuation. Withdrawal symptoms typically begin within 24 h of abstinence and manifest as irritability, nervousness, sleep disturbances and decreased appetite. There is growing evidence that supports the use of plant-derived and synthetic cannabinoids for the treatment of cannabis withdrawal. In this case report, we present 20-year-old woman who developed protracted nausea and vomiting secondary to cannabis withdrawal and was successfully treated with nabilone. Nausea and vomiting is not listed in the Diagnostic and Statistical Manual-5 diagnostic criteria for cannabis withdrawal syndrome and is an uncommon symptom presentation. 2014 BMJ Publishing Group Ltd.

Effects of the mGluR5 antagonist MPEP on ethanol withdrawal induced anxiety-like syndrome in rats.

Abstinence from chronic ethanol consumption leads to the manifestation of a variety of symptoms attributed to central nervous system hyperexcitability, such as increased irritability, anxiety, and restlessness. Recent studies have demonstrated the importance of metabotropic glutamate receptor 5 (mGluR5) in addictive behaviours. This study investigates the effects of the mGluR5 antagonist 2-methyl-6-(phenylethynyl)-pyridine (MPEP) on ethanol withdrawal induced anxiety using two behavioural paradigms. Male Wistar rats were fed a Modified Liquid Diet (MLD) containing low fat cow milk, sucrose, and maltodextrin with a gradual introduction of 2.4%, 4.8% and 7.2% ethanol for 20 days. Six hours into ethanol withdrawal, the rats were intraperitoneally injected with normal saline and MPEP (2.5, 5.0, 10, 20, 30 mg/kg) and were assessed for ethanol withdrawal induced anxiety-like syndrome using an automated elevated plus maze and an open field. MPEP at 10 mg/kg significantly attenuated ethanol withdrawal induced anxiety without any compromising effects on locomotor activities. Despite reversing several indices of ethanol withdrawal induced anxiety in both the elevated plus maze and the open field, low doses of MPEP (2.5, 5 mg/kg) significantly compromised the locomotor activities of ethanol withdrawn rats. High doses of MPEP (20 and 30 mg/kg) significantly attenuated withdrawal anxiety when tested in the elevated plus maze but not in the open field. Administration of MPEP (2.5, 5, 10, 20, 30 mg/kg) has no significant compromising effect on the locomotor activities of ethanol naïve rats. Despite significantly reducing withdrawal anxiety in both behavioural paradigms at 10 mg/kg, the compromising effects of low and high doses of MPEP must be further explored along with the therapeutic efficiency of this drug for relieving withdrawal induced anxiety.

Alcohol abuse and dependence represents a most serious health problem worldwide with major social, interpersonal and legal interpolations. Besides benzodiazepines, anticonvulsants are often used for the treatment of alcohol withdrawal symptoms. Anticonvulsants drugs are indicated for the treatment of alcohol withdrawal syndrome, alone or in combination with benzodiazepine treatments. In spite of the wide use, the exact role of the anticonvulsants for the treatment of alcohol withdrawal has not yet bee adequately assessed. To evaluate the effectiveness and safety of anticonvulsants in the treatment of alcohol withdrawal. We searched Cochrane Drugs and Alcohol Group' Register of Trials (December 2009), PubMed, EMBASE, CINAHL (1966 to December 2009), EconLIT (1969 to December 2009). Parallel searches on web sites of health technology assessment and related agencies, and their databases. Randomized controlled trials (RCTs) examining the effectiveness, safety and overall risk-benefit of anticonvulsants in comparison with a placebo or other pharmacological treatment. All patients were included regardless of age, gender, nationality, and outpatient or inpatient therapy. Two authors independently screened and extracted data from studies. Fifty-six studies, with a total of 4076 participants, met the inclusion criteria. Comparing anticonvulsants with placebo, no statistically significant differences for the six outcomes considered.Comparing anticonvulsant versus other drug, 19 outcomes considered, results favour anticonvulsants only in the comparison carbamazepine versus benzodiazepine (oxazepam and lorazepam) for alcohol withdrawal symptoms (CIWA-Ar score): 3 studies, 262 participants, MD -1.04 (-1.89 to -0.20), none of the other comparisons reached statistical significance.Comparing different anticonvulsants no statistically significant differences in the two outcomes considered.Comparing anticonvulsants plus other drugs versus other drugs (3 outcomes considered), results

Aloe vera is a medicinal herb used as an anti-inflammatory and sedative agent. The current study aimed to evaluate the effect of Aloe vera aqueous extract on morphine withdrawal symptoms in morphine-dependent female rats. The current research was performed on 40 female Wista-Albino rats which were made dependent on morphine using Houshyar protocol and were randomly divided into five groups (A, B, C, D, and E). Group A did not receive any agent in the period of handling but other groups (B, C, D and E) received 5, 10, 20 and 40 mg/kg of Aloe vera aqueous extract by gavage, three times daily for a week, respectively. Withdrawal symptoms, stool form, agitation, disparity, floppy eyelids, and body mass variations were checked for 10 days. The obtained data were analyzed using SPSS v.11 software, and Friedman, Kruskal-Wallis, and Mann-Whitney statistical tests. Statistical difference was considered significant (P < 0.05). The results of the present study showed that agitation, disparity, and floppy eyelids in group E were significantly higher than those of others groups; however, these symptoms in group C were significantly lower than those of the other groups. The results of the present study revealed that the Aloe vera aqueous extract had various effects on morphine withdrawal syndrome in morphine-dependent female rats .

To evaluate the use and impact of the recommended withdrawal time of at least 6 minutes from the cecum in colonoscopy in multiple gastroenterology endoscopy ambulatory surgery centers serving a wide geographical area. An observational prospective multicenter quality assurance review was conducted in 49 ambulatory surgery centers in 17 states with 315 gastroenterologists. There was no intervention with this quality assessment program as care of patients and the routine of gastroenterologists continued as standard practice. Multivariable analysis was applied to the database to examine factors affecting withdrawal time and polyp detection. There were 15,955 consecutive qualified patients receiving colonoscopies in a designated 4-week period. Gastroenterologists with average withdrawal times of 6 minutes or more in patients with no polyps were 1.8 times more likely to detect 1 or more polyps and had a significantly higher rate (P<0.0001) of polyp detection in patients with findings of polyps compared to gastroenterologists with average withdrawal times of less than 6 minutes in patients with no polyps. For patients with no pathology, the mean time of withdrawal was 6.98 (SD=4.34) minutes and for patients with pathology mean time of withdrawal was 11.27 (SD=6.71) minutes. Strongest predictors of withdrawal time of 6 minutes or more were presence of carcinoma (3.7 times more likely than those with no pathology), adenoma (2.0 times more likely than those with no pathology), and number of polyps visualized (1.7 times more likely for each polyp). This quality assurance assessment from standard colonoscopy practices of 315 gastroenterologists in 49 endoscopic ambulatory surgery centers serving a wide geographical area provides support for the merits of a colonoscopy withdrawal time from the cecum of 6 minutes or more to improve the detection of polyps.

Pleiotrophin modulates morphine withdrawal but has no effects on morphine-conditioned place preference.

Gramage, Esther; Vicente-Rodríguez, Marta; Herradón, Gonzalo

Pleiotrophin (PTN) is a neurotrophic factor with important functions in addiction and neurodegenerative disorders. Morphine administration induces an increase in the expression of PTN and Midkine (MK), the only other member of this family of cytokines, in brain areas related with the addictive effects of drug of abuse, like the Ventral Tegmental Area or the hippocampus. In spite of previous studies showing that PTN modulates amphetamine and ethanol rewarding effects, and that PTN is involved in morphine-induced analgesia, it was still unknown if the rewarding effects of morphine may be regulated by endogenous PTN. Thus, we aim to study the role of PTN in the reward and physical dependence induced by morphine. We used the Conditioned Place Preference (CPP) paradigm in PTN genetically deficient (PTN-/-) and wild type (WT) mice to assess the rewarding effects of morphine in absence of endogenous PTN. Second, to study if PTN may be involved in morphine physical dependence, naloxone-precipitated withdrawal syndrome was induced in PTN-/- and WT morphine dependent mice. Although the increase in the time spent in the morphine-paired compartment after conditioning tended to be more pronounced in PTN-/- mice, statistical significance was not achieved. The data suggest that PTN does not exert an important role in morphine reward. However, our results clearly indicate that PTN-/- mice develop a more severe withdrawal syndrome than WT mice, characterized as a significant increase in the time standing and in the total incidences of forepaw licking, forepaw tremors, wet dog shake and writhing. The data presented here suggest that PTN is a novel genetic factor that plays a role in morphine withdrawal syndrome. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Time-course of the DSM-5 cannabis withdrawal symptoms in poly-substance abusers

2013-01-01

Background Evidence is accumulating that a cannabis withdrawal syndrome is common, of clinical significance, and has a clear time course. Up till now, very limited data exist on the cannabis withdrawal symptoms in patients with co-morbid substance use disorders, other than cannabis use and tobacco use. Methods Symptoms of withdrawal were assessed through patient self-reports during detoxification in Danish residential rehabilitation centers. Patients (n = 90) completed booklets three times during their first month at the treatment centre. Self-reported withdrawal symptoms was rated using the DSM-5 Withdrawal Symptom Check List with withdrawal symptoms from all classes of substances, with no indication that the described symptoms should be attributed to withdrawal. Self-reported time since last use of cannabis was used as a predictor of cannabis withdrawal severity. Results With the exception of loss of appetite, time since last use of cannabis was associated with all types of withdrawal symptoms listed in the DSM-5. Only four of 19 symptoms intended to measure withdrawal from other substances were related to time since last use of cannabis, including vivid, unpleasant dreams. Conclusions The findings yield strong support to the notion of a cannabis withdrawal syndrome, and gives further evidence for the inclusion of the criterion of vivid, unpleasant dreams. Further, the findings speak against the significance of demand characteristics in determining the course of the symptoms of cannabis withdrawal. PMID:24118963

Background The incidence of neonatal opioid withdrawal is increasing in both Canada and the United States. However, the degree to which the treatment of pain with opioids, rather than the misuse of prescription opioids or heroin, contributes to the prevalence of neonatal opioid withdrawal remains unknown. Methods We conducted a retrospective, population-based, cross-sectional study between 1992 and 2011 in Ontario with 2 objectives. First, we determined the annual incidence of neonatal abstinence syndrome. Second, using data from a subset of women eligible for publicly funded prescription drugs, we determined what proportion of women who deliver an infant with neonatal abstinence syndrome were given a prescription for an opioid before and during pregnancy. Results The incidence of neonatal abstinence syndrome in Ontario increased 15-fold during the study period, from 0.28 per 1000 live births in 1992 to 4.29 per 1000 live births in 2011. During the final 5 years of the study, we identified 927 deliveries of infants with neonatal abstinence syndrome to mothers who were public drug plan beneficiaries. Of these mothers, 67% had received an opioid prescription in the 100 days preceding delivery, including 53.3% who received methadone, an increase from 28.6% in the interval spanning 1 to 2 years before delivery (p < 0.001). Prescription for nonmethadone opioids decreased from 38% to 17% (p < 0.001). Interpretation The incidence of neonatal opioid withdrawal in Ontario has increased substantially over the last 20 years. Most of the women in this cohort who delivered an infant with neonatal abstinence syndrome had received a prescription for an opioid both before and during their pregnancy. PMID:25844370

Social withdrawal is a new mental health problem increasingly common, present in different cultures, whose psychopathology and treatment is not yet established. This study aims to determine the socio-demographic and clinical features and possible clinical subtypes that predict the 12-month outcomes of cases with hikikomori syndrome, a severe form of social withdrawal. Socio-demographic and clinical data at baseline were analysed as well as data obtained for 12 months after at-home treatment in 190 cases. The inclusion criteria were: spending all time at home, avoiding social situations and relationships, significant deterioration due to social isolation, with a minimum duration of 6 months. Six major diagnostic groups were identified: affective, anxiety, psychotic, drug use, personality and other Axis I disorders. The anxiety-affective subgroup demonstrated lower clinical severity, but worse evolution. Less than half of the cases were available for medical follow-up at 12-months. Subjects undergoing intensive treatment had a higher medical follow-up rate and better social networks at 12-months. Therefore, our findings provide data to reach consensus on the specific characteristics of social isolation hikikomori syndrome. The analysis demonstrated the fragility and tendency to relapse and have disengagement, particularly relevant in the anxiety-affective subgroup, suggesting that intensive treatments are more effective.

This study examined the determinants of social withdrawal using data from a survey by the Tokyo Metropolitan Government Office for Youth Affairs and Public Safety (2008). In addition, this study identified young people who showed an affinity for social withdrawal although they were not in a state of withdrawal, and examined the determinants of an affinity for social withdrawal. The results of stepwise discriminant analysis showed that factors such as social phobia, depression, violence, and emotional bonds with family differentiated between the general youth group and the social withdrawal group and the "affinity group". Social phobia, violence, and refusal to be interfered in self-decision making differentiated between the social withdrawal group and the "affinity group". This study shows that an "affinity group" should be cared as well as an actual withdrawal group.

This study was performed to determine the effects in the general population of ending one's dietary intake of caffeine. We studied 62 normal adults whose intake of caffeine was low to moderate (mean amount, 235 mg--the equivalent of 2.5 cups of coffee--per day). They completed questionnaires about symptoms and tests of their mood and performance when consuming their normal diets (base-line period) and at the end of each of two two-day periods during which they consumed caffeine-free diets and under double-blind conditions received capsules containing placebo (placebo period) or caffeine (caffeine period) in amounts equal to their daily caffeine consumption. More subjects had abnormally high Beck Depression Inventory scores (11 percent), high scores on the trait scale of the State-Trait Anxiety Inventory (8 percent), low vigor scores (11 percent) and high fatigue scores (8 percent) on the Profile of Mood States, and moderate or severe headache (52 percent) during the placebo period than during either the base-line period (2, 0, 0, 0, and 2 percent, respectively; P less than 0.05) or the caffeine period (3, 2, 2, 0, and 6 percent; P less than 0.05). More subjects reported unauthorized use of medications during the placebo period (13 percent) than during the caffeine period (2 percent, P = 0.017). Performance of a tapping task was slower during the placebo period than during the base-line and caffeine periods (P less than 0.01). Persons who consume low or moderate amounts of caffeine may have a withdrawal syndrome after their daily consumption of caffeine ceases.

Physician turnover threatens continuity of care for patients and is a huge expense for health care organizations. Health care organizations have been advised to help physicians build positive relations with colleagues, staff, and patients as a strategy to socially integrate physicians in the workplace and to increase physician retention. Although these recommendations are touted as "evidence-based" practices, the importance of workplace relationships for physician retention has not been established empirically. The purpose of this study is to examine two questions: Are physicians who report better relationships with colleagues, staff, and patients less likely to intend to withdraw from practice? Do the effects of these relational factors differ for large-group and solo/small-group practice physicians? Using data from the Physician Worklife Survey, we analyzed the associations between physicians' reported relationships with colleagues, staff, and patients and intention to withdraw from practice within 2 years using logistic regression. : Relationships with colleagues had a significant and negative association with intended withdrawal from practice for large-group practice physicians. The joint effect of relationships with colleagues, staff, and patients was significant for large-group practice physicians, but it only approached significance for solo/small-group practice physicians. This study suggests that workplace relationships may influence physicians' intention to withdraw from practice, but the mechanisms by which they do so are unclear. Possible interventions to improve physician retention include promotion of informal mentoring and efforts to support community involvement of physicians and their families. Further research examining the role of these and other programs in promoting physician retention can help employers to foster positive workplace relationships and improve retention.

Alcohol use disorder is underdiagnosed and undertreated, and up to 50% of alcohol-abstinent patients diagnosed with alcohol dependence relapse within the first year of treatment. Current treatments for the maintenance of alcohol abstinence in patients with alcohol use disorder have limited efficacy, and there is an urgent need for novel treatment strategies. Decreased cerebral glucose metabolism and increased brain uptake of acetate were recently reported in heavy drinkers, relative to controls. Given the switch of metabolic fuel from glucose to acetate in the alcohol-dependent brain, we investigated the potential therapeutic benefit of a ketogenic diet in managing alcohol withdrawal symptoms during detoxification. Male Sprague Dawley rats fed either ketogenic or regular diet were administered ethanol or water orally, twice daily for 6 days while the diet conditions were maintained. Abstinence symptoms were rated 6, 24, 48, and 72 hours after the last alcohol administration. Maintenance on a ketogenic diet caused a significant decrease in the alcohol withdrawal symptoms' "rigidity" and "irritability." Our preclinical pilot study suggests that a ketogenic diet may be a novel approach for treating alcohol withdrawal symptoms in humans. Copyright © 2017 by the Research Society on Alcoholism.

It was recently suggested that early postoperative seizure relapse implicates a failure to define and resect the epileptogenic zone, that late recurrences reflect the persistence or re-emergence of epileptogenic pathology, and that early recurrences are associated with poor treatment response. Timing of antiepileptic drugs withdrawal policies, however, have never been taken into account when investigating time to relapse following epilepsy surgery. Of the European paediatric epilepsy surgery cohort from the "TimeToStop" study, all 95 children with postoperative seizure recurrence following antiepileptic drug (AED) withdrawal were selected. We investigated how time intervals from surgery to AED withdrawal, as well as other previously suggested determinants of (timing of) seizure recurrence, related to time to relapse and to relapse treatability. Uni- and multivariable linear and logistic regression models were used. Based on multivariable analysis, a shorter interval to AED reduction was the only independent predictor of a shorter time to relapse. Based on univariable analysis, incomplete resection of the epileptogenic zone related to a shorter time to recurrence. Timing of recurrence was not related to the chance of regaining seizure freedom after reinstallation of medical treatment. For children in whom AED reduction is initiated following epilepsy surgery, the time to relapse is largely influenced by the timing of AED withdrawal, rather than by disease or surgery-specific factors. We could not confirm a relationship between time to recurrence and treatment response. Timing of AED withdrawal should be taken into account when studying time to relapse following epilepsy surgery, as early withdrawal reveals more rapidly whether surgery had the intended curative effect, independently of the other factors involved.

Hikikomori, a severe form of social withdrawal syndrome, is a growing social issue in Japan and internationally. The pathophysiology of hikikomori has not yet been elucidated and an effective treatment remains to be established. Recently, we revealed that avoidant personality disorder is the most common comorbidity of hikikomori. Thus, we have postulated that avoidant personality is the personality underpinning hikikomori. First, we herein show relationships between avoidant personality traits, blood biomarkers, hikikomori-related psychological features, and behavioural characteristics assessed by a trust game in non-hikikomori volunteers. Avoidant personality traits were negatively associated with high-density lipoprotein cholesterol (HDL-C) and uric acid (UA) in men, and positively associated with fibrin degeneration products (FDP) and high sensitivity C-reactive protein (hsCRP) in women. Next, we recruited actual individuals with hikikomori, and compared avoidant personality traits, blood biomarkers, and psychological features between individuals with hikikomori and age-matched healthy controls. Individuals with hikikomori had higher avoidant personality scores in both sexes, and showed lower serum UA levels in men and lower HDL-C levels in women compared with healthy controls. This is the first report showing possible blood biomarkers for hikikomori, and opens the door to clarify the underlying biological pathophysiology of hikikomori.

Catastrophic antiphospholipid syndrome (APS) is caused by thrombotic vascular occlusions that affect both small and large vessels, producing ischaemia in the affected organs. The “catastrophic” variant of the antiphospholipid syndrome (cAPS) develops over a short period of time. Although patients with cAPS represent <1% of all patients with APS, they are usually life threatening with a 50% mortality rate. A strong association with concomitant infection is thought to act as the main trigger of microthromboses in cAPS. Several theories have been proposed to explain these physiopathological features. Some of them suggest the possibility of molecular mimicry between components of infectious microorganisms and natural anticoagulants, which might be involved in the production of cross-reacting antiphospholipid antibodies. We present a case of catastrophic cerebral APS characterised by massive temporal lobe infarction and subsequent haemorrhagic transformation after sudden withdrawal of warfarin. PMID:22242060

The corticotropin-releasing factor receptor-1 pathway mediates the negative affective states of opiate withdrawal.

Contarino, Angelo; Papaleo, Francesco

The negative affective symptoms of opiate withdrawal powerfully motivate drug-seeking behavior and may trigger relapse to heroin abuse. To date, no medications exist that effectively relieve the negative affective symptoms of opiate withdrawal. The corticotropin-releasing factor (CRF) system has been hypothesized to mediate the motivational effects of drug dependence. The CRF signal is transmitted by two distinct receptors named CRF receptor-1 (CRF1) and CRF2. Here we report that genetic disruption of CRF1 receptor pathways in mice eliminates the negative affective states of opiate withdrawal. In particular, neither CRF1 receptor heterozygous (CRF1+/-) nor homozygous (CRF1-/-) null mutant mice avoided environmental cues repeatedly paired with the early phase of opiate withdrawal. These results were not due to altered associative learning processes because CRF1+/- and CRF1-/- mice displayed reliable, conditioned place aversions to environmental cues paired with the kappa-opioid receptor agonist U-50,488H. We also examined the impact of CRF1 receptor-deficiency upon opiate withdrawal-induced dynorphin activity in the nucleus accumbens, a brain molecular mechanism thought to underlie the negative affective states of drug withdrawal. Consistent with the behavioral indices, we found that, during the early phase of opiate withdrawal, neither CRF1+/- nor CRF1-/- showed increased dynorphin mRNA levels in the nucleus accumbens. This study reveals a cardinal role for CRF/CRF1 receptor pathways in the negative affective states of opiate withdrawal and suggests therapeutic strategies for the treatment of opiate addiction.

Recently, khat chewing has become a common practice among high school, college, and university students. Regular khat chewing is thought to be a predisposing factor for different physical and mental health problems. It can lead to absenteeism from work and classes. In Ethiopia, to our knowledge no published study has investigated khat withdrawal symptoms. Therefore, this study was conducted to determine the prevalence, withdrawal symptoms, and associated factors of khat chewing among regular undergraduate students on the main campus of Jimma University in Ethiopia. The institution-based, cross-sectional study was conducted in January 2016. Data were collected from 651 main campus regular undergraduate students with a structured, self-administered questionnaire, entered into Epidata 3.1 and exported to SPSS version 20 for Windows. Bivariate and multivariate logistic regressions were used to explore associations and identify variables independently associated with khat chewing. The study found that the lifetime and current prevalence of khat chewing among students were 26.3% (95% CI: 24.3, 28.3) and 23.9% (95% CI: 21.94, 25.86), respectively. About 25.7% of students started chewing after joining university, and 60.5% of these students started during their first year. The main reason given for starting khat chewing was for study purposes (54.6%), followed by socialization purposes (42.3%). Among current khat chewers, 72.9% reported that they had chewed khat for 1 year or more and 68.2% reported that they had experienced various withdrawal symptoms. The most frequently reported withdrawal symptoms were feeling depressed, craving, and feeling fatigued. Being male, attending a place of worship daily/2-3 times per week, cannabis use, smoking cigarettes, and having family members currently chewing khat were independently associated with khat chewing. This study found that large numbers of university students were currently chewing khat. In this study withdrawal symptoms

Baclofen is commonly used to treat spasticity of central etiology. Unfortunately, a potentially lethal withdrawal syndrome can complicate its use. This is especially true when the drug is administered intrathecally. There are very few cases of baclofen withdrawal leading to reversible cardiomyopathy described in the literature. The authors present a patient with a history of chronic intrathecal baclofen use who, in the setting of acute baclofen withdrawal, develops laboratory, electrocardiogram, and echocardiogram abnormalities consistent with cardiomyopathy. Upon reinstitution of intrathecal baclofen, the cardiomyopathy and associated abnormalities quickly resolve. Although rare, it is crucial to be aware of this reversible cardiomyopathy to ensure its prompt diagnosis and treatment.

Withdrawal: Expanding a Key Addiction Construct

PubMed Central

2015-01-01

Withdrawal is an essential component of classical addiction theory; it is a vital manifestation of dependence and motivates relapse. However, the traditional conceptualization of withdrawal as a cohesive collection of symptoms that emerge during drug deprivation and decline with either the passage of time or reinstatement of drug use, may be inadequate to explain scientific findings or fit with modern theories of addiction. This article expands the current understanding of tobacco withdrawal by examining: (1) withdrawal variability; (2) underlying causes of withdrawal variability, including biological and person factors, environmental influences, and the influence of highly routinized behavioral patterns; (3) new withdrawal symptoms that allow for enhanced characterization of the withdrawal experience; and (4) withdrawal-related cognitive processes. These topics provide guidance regarding the optimal assessment of withdrawal and illustrate the potential impact modern withdrawal conceptualization and assessment could have on identifying treatment targets.

Anxiety states, including those arising during acute or protracted withdrawal periods, may be precipitating factors in alcoholic relapse. Given the cyclical nature of ethanol withdrawal associated with repeated cycles of ethanol intake and abstinence in a pattern that often spans years, meaningful attempts to model ethanol withdrawal-associated anxiety should incorporate cycled ethanol treatments. The studies reported herein examined the effects of gamma-aminobutyric acid-modulating drugs on social interaction behavior-an established model of anxiety-in rats exposed to repeated cycles of ethanol treatment and withdrawal. Rats were exposed to 8 to 12 g/kg/day ethanol during three 7-day dietary cycles (5 days on ethanol diet followed by 2 days on control diet). Ethanol was administered either at hour 4 of withdrawal after cessation of each of the first 2 ethanol cycles or during the final withdrawal only. In other groups, the early withdrawals were treated with alphaxalone, diazepam, PK11159, or flumazenil to block anxiety-like behavior during an untreated later (third) withdrawal. The benzodiazepine inverse agonist DMCM (methyl-6, 7-dymerhoxy-4-ethyl-beta-carboline-3-carboxylate) was also given repeatedly to determine whether it would sensitize anxiety-like behavior during a future withdrawal. Finally, the effects of all drugs on deficits in locomotor behavior were assessed. Pretreatment of earlier withdrawals with alphaxalone, diazepam, ethanol, or flumazenil reduced social interaction deficits during a later withdrawal, but pretreatment with PK11195 did not. In contrast, DMCM administered in lieu of early withdrawals increased social interaction deficits during an untreated later withdrawal. Locomotor deficits were significantly reversed only by the acute ethanol and diazepam treatment during the final withdrawal.

Methamphetamine (METH) is a widely abused illegal psychostimulant, which is confirmed to be neurotoxic and of great damage to human. Studies on the role of brain-derived neurotrophic factor (BDNF) in human METH addicts are limited and inconsistent. The purposes of this study are to compare the serum BDNF levels between METH addicts and healthy controls during early withdrawal, and explore the changes of serum BDNF levels during the first month after METH withdrawal.179 METH addicts and 90 age- and gender-matched healthy controls were recruited in this study. We measured serum BDNF levels at baseline (both METH addicts and healthy controls) and at 1 month after abstinence of METH (METH addicts only).Serum BDNF levels of METH addicts at baseline were significantly higher than controls (1460.28  ±  490.69 vs 1241.27  ±  335.52  pg/mL; F = 14.51, P < 0.001). The serum BDNF levels of 40 METH addicts were re-examined after 1 month of METH abstinence, which were significantly lower than that at baseline (1363.70  ±  580.59 vs 1621.41  ±  591.07  pg/mL; t = 2.26, P = .03), but showed no differences to the controls (1363.70  ±  580.59 vs 1241.27  ±  335.52  pg/mL; F = 2.29, P = 0.13).Our study demonstrated that serum BDNF levels were higher in METH addicts than controls during early withdrawal, and were time dependent decreased during the first month of abstinence. These findings may provide further evidence that increased serum BDNF levels may be associated with the pathophysiology of METH addiction and withdrawal and may be a protective response against the subsequent METH-induced neurotoxicity. Besides, these findings may also promote the development of medicine in the treatment of METH addiction and withdrawal.

HMG-CoA Reductase Inhibitors (statins) reduce cardiac event rates in patients with stable coronary heart disease. Withdrawal of chronic statin treatment during acute coronary syndromes may impair vascular function independent of lipid-lowering effects and thus increase cardiac event rate. We investigated the effects of statins on the cardiac event rate in 1616 patients of the Platelet Receptor Inhibition in Ischemic Syndrome Management (PRISM) study who had coronary artery disease and chest pain in the previous 24 hours. We recorded death and nonfatal myocardial infarction during the 30-day follow-up. Baseline clinical characteristics did not differ among 1249 patients without statin therapy, 379 patients with continued statin therapy, and 86 patients with discontinued statin therapy after hospitalization. Statin therapy was associated with a reduced event rate at 30-day follow-up compared with patients without statins (adjusted hazard ratio, 0.49 [95% CI, 0.21 to 0.86]; P=0.004). If the statin therapy was withdrawn after admission, cardiac risk increased compared with patients who continued to receive statins (2.93 [95% CI, 1.64 to 6.27]; P=0.005) and tended to be higher compared with patients who never received statins (1.69 [95% CI, 0.92 to 3.56]; P=0.15). This was related to an increased event rate during the first week after onset of symptoms and was independent of cholesterol levels. In a multivariate model, troponin T elevation (P=0.005), ST changes (P=0.02), and continuation of statin therapy (P=0.008) were the only independent predictors of patient outcome. Statin pretreatment in patients with acute coronary syndromes is associated with improved clinical outcome. However, discontinuation of statins after onset of symptoms completely abrogates this beneficial effect.

Acknowledging separable factors underlying negative symptoms may lead to better understanding and treatment of negative symptoms in individuals with schizophrenia. The current study aimed to test whether the negative symptoms factor (NSF) of the Positive and Negative Syndrome Scale (PANSS) would be better represented by expressive and experiential deficit factors, rather than by a single factor model, using confirmatory factor analysis (CFA). Two hundred and twenty individuals with schizophrenia spectrum disorders completed the PANSS; subsamples additionally completed the Brief Negative Symptom Scale (BNSS) and the Motivation and Pleasure Scale-Self-Report (MAP-SR). CFA results indicated that the two-factor model fit the data better than the one-factor model; however, latent variables were closely correlated. The two-factor model's fit was significantly improved by accounting for correlated residuals between N2 (emotional withdrawal) and N6 (lack of spontaneity and flow of conversation), and between N4 (passive social withdrawal) and G16 (active social avoidance), possibly reflecting common method variance. The two NSF factors exhibited differential patterns of correlation with subdomains of the BNSS and MAP-SR. These results suggest that the PANSS NSF would be better represented by a two-factor model than by a single-factor one, and support the two-factor model's adequate criterion-related validity. Common method variance among several items may be a potential source of measurement error under a two-factor model of the PANSS NSF.

Chronic alcohol use induces adaptations and toxicity that can induce symptoms of anxiety, autonomic hyperarousal, and epileptic seizures when alcohol is removed (withdrawal syndrome). Zebrafish has recently gained wide attention as a behavioral model to study the neurobehavioral effects of acute and chronic alcohol use, including withdrawal. The literature, however, is very contradictory on findings regarding withdrawal effects, with some studies reporting increased anxiety, while others report no effect. A meta-analytic approach was taken to find the sources of this heterogeneity, and ethanol concentration during exposure and exposure duration were found to be the main sources of variation. A conceptual replication was also made using continuous exposure for 16 days in waterborne ethanol (0.5%) and assessing anxiety-like behavior in the light/dark test after 60 min withdrawal. Withdrawal was shown to reduce preference for darkness, consistent with decreased anxiety, but to increase risk assessment, consistent with increased anxiety. Animals were also subjected to the withdrawal protocol and injected with pilocarpine in a sub-convulsive dose to assess susceptibility to epileptic seizure-like behavior. The protocol was sufficient to increase susceptibility to epileptic seizure-like behavior in animals exposed to ethanol. Finally, withdrawal also decreased catalase activity in the brain, but not in the head kidney, suggesting mechanisms associated with the behavioral effects of ethanol withdrawal.

Effects of corticotropin-releasing factor receptor-1 antagonists on the brain stress system responses to morphine withdrawal.

Navarro-Zaragoza, Javier; Núñez, Cristina; Laorden, M Luisa; Milanés, M Victoria

2010-05-01

The role of stress in drug addiction is well established. The negative affective states of withdrawal most probably involve recruitment of brain stress neurocircuitry [e.g., induction of hypothalamo-pituitary-adrenocortical (HPA) axis, noradrenergic activity, and corticotropin-releasing factor (CRF) activity]. The present study investigated t$he role of CRF receptor-1 subtype (CRF1R) on the response of brain stress system to morphine withdrawal. The effects of naloxone-precipitated morphine withdrawal on noradrenaline (NA) turnover in the paraventricular nucleus (PVN), HPA axis activity, signs of withdrawal, and c-Fos expression were measured in rats pretreated with vehicle, CP-154526 [N-butyl-N-ethyl-2,5-dimethyl-7-(2,4,6-trimethylphenyl)pyrrolo[3,2-e]pyrimidin-4-amine], or antalarmin (selective CRF1R antagonists). Tyrosine hydroxylase-positive neurons expressing CRF1R were seen at the level of the nucleus tractus solitarius-A(2) cell group in both control and morphine-withdrawn rats. CP-154526 and antalarmin attenuated the increases in body weight loss and irritability that were seen during naloxone-induced morphine withdrawal. Pretreatment with CRF1R antagonists resulted in no significant modification of the increased NA turnover at PVN, plasma corticosterone levels, or c-Fos expression that was seen during naloxone-induced morphine withdrawal. However, blockade of CRF1R significantly reduced morphine withdrawal-induced increases in plasma adrenocorticotropin levels. These results suggest that the CRF1R subtype may be involved in the behavioral and somatic signs and in adrenocorticotropin release (partially) during morphine withdrawal. However, CRF1R activation may not contribute to the functional interaction between NA and CRF systems in mediating morphine withdrawal-activation of brain stress neurocircuitry.

Opiates are essential for treating pain, but termination of opiate therapy can cause a debilitating withdrawal syndrome in chronic users. To alleviate or avoid the aversive symptoms of withdrawal, many of these individuals continue to use opiates. Withdrawal is therefore a key determinant of opiate use in dependent individuals, yet its underlying mechanisms are poorly understood and effective therapies are lacking. Here, we identify the pannexin-1 (Panx1) channel as a therapeutic target in opiate withdrawal. We show that withdrawal from morphine induces long-term synaptic facilitation in lamina I and II neurons within the rodent spinal dorsal horn, a principal site of action for opiate analgesia. Genetic ablation of Panx1 in microglia abolished the spinal synaptic facilitation and ameliorated the sequelae of morphine withdrawal. Panx1 is unique in its permeability to molecules up to 1 kDa in size and its release of ATP. We show that Panx1 activation drives ATP release from microglia during morphine withdrawal and that degrading endogenous spinal ATP by administering apyrase produces a reduction in withdrawal behaviors. Conversely, we found that pharmacological inhibition of ATP breakdown exacerbates withdrawal. Treatment with a Panx1-blocking peptide ( 10 panx) or the clinically used broad-spectrum Panx1 blockers, mefloquine or probenecid, suppressed ATP release and reduced withdrawal severity. Our results demonstrate that Panx1-mediated ATP release from microglia is required for morphine withdrawal in rodents and that blocking Panx1 alleviates the severity of withdrawal without affecting opiate analgesia.

High-dose benzodiazepine dependence: a qualitative study of patients' perception on cessation and withdrawal.

Benzodiazepine withdrawal syndrome has been reported following attempts to withdraw even from low or therapeutic doses and has been compared to barbiturate and alcohol withdrawal. This experience is known to deter patients from future cessation attempts. Research on other psychotropic substances shows that the reasons and motivations for withdrawal attempts - as well as the experiences surrounding those attempts - at least partially predict future efforts at discontinuation as well as relapse. We therefore aimed to qualitatively explore what motivates patients to discontinue this medication as well as to examine their experiences surrounding previous and current withdrawal attempts and treatment interventions in order to positively influence future help-seeking behavior and compliance. To understand these patients better, we conducted a series of 41 unstructured, narrative, in-depth interviews among adult Swiss patients with a long-term dependent use of benzodiazepines in doses equivalent to more than 40 mg diazepam per day and/or otherwise problematic use (mixing benzodiazepines, escalating dosage, recreational use or illegal purchase). Mayring's qualitative content analysis was used to evaluate findings. These high-dose benzodiazepine-dependent patients decision to change consumption patterns were affected by health concerns, the feeling of being addicted and social factors. Discontinuation attempts were frequent and not very successful with fast relapse. Withdrawal was perceived to be a difficult, complicated, and highly unpredictable process. The first attempt at withdrawal occurred at home and typically felt better than at the clinic. Inpatient treatment was believed to be more effective with long term treatment (approaches) than short term. Patients preferred gradual reduction of usage to abrupt cessation (and had experienced both). While no clear preferences for withdrawal were found for benzodiazepines with specific pharmacokinetic properties, participants

To study seizure outcome after antiepilepsy drug (AED) withdrawal in brain tumor patients and to analyze risk factors for seizure recurrence. Brain tumor patients with seizures and at least one attempt at AED discontinuation were identified from the hospital database and neurology clinic records. After defining study variables, patient charts were abstracted for clinical and demographic data. Statistical analyses used log-rank tests and multivariable Cox proportional hazards models. Sixty-two patients discontinued AEDs at a median time of 5.6 years from the first seizure (range, 1.2-19.6 years). Median time since AED withdrawal was 2.3 years (range, 0.4-15.1 years). Seizures recurred in 17 (27%) patients within a median time of 0.8 years (range, 0.06-7.7 years). Median seizure-free period before AED withdrawal was 1.3 years (range, 0.1-11 years). More than one tumor resection and whole-brain radiation treatment (WBRT) were associated with seizure recurrence, whereas posterior fossa tumor location was correlated with reduced seizure recurrence risk. At seizure recurrence, control was easily reestablished in 10 patients with AED reinstitution and after dose adjustment in five; two patients with poor drug compliance continue to have seizures. In 48 patients who had an EEG before AED withdrawal, spikes or slow waves did not correlate with seizure recurrence. AED withdrawal can be successfully achieved in majority of carefully selected patients. WBRT and multiple tumor resections seem to be associated with an increased hazard for seizure recurrence.

Few studies examined treatments for amphetamine withdrawal, although it is a common problem among amphetamine users. Its symptoms, in particular intense craving, may be a critical factor leading to relapse to amphetamine use. In clinical practice, medications for cocaine withdrawal are commonly used to manage amphetamine withdrawal although the pharmacodynamic and pharmacokinetic properties of these two illicit substances are different. To assess the effectiveness of pharmacological alone or in combination with psychosocial treatment for amphetamine withdrawals on discontinuation rates, global state, withdrawal symptoms, craving, and other outcomes. MEDLINE (1966 - 2008), CINAHL (1982 - 2008), PsycINFO (1806 - 2008), CENTRAL (Cochrane Library 2008 issue 2), references of obtained articles. All randomised controlled and clinical trials evaluating pharmacological and or psychosocial treatments (alone or combined) for people with amphetamine withdrawal symptoms. Two authors evaluated and extracted data independently. The data were extracted from intention-to-treat analyses. The Relative Risk (RR) with the 95% confidence interval (95% CI) was used to assess dichotomous outcomes. The Weighted Mean Difference (WMD) with 95% CI was used to assess continuous outcomes. Four randomised controlled trials (involving 125 participants) met the inclusion criteria for the review. Two studies found that amineptine significantly reduced discontinuation rates and improved overall clinical presentation, but did not reduce withdrawal symptoms or craving compared to placebo. The benefits of mirtazapine over placebo for reducing amphetamine withdrawal symptoms were not as clear. One study suggested that mirtazapine may reduce hyperarousal and anxiety symptoms associated with amphetamine withdrawal. A more recent study failed to find any benefit of mirtazapine over placebo on retention or on amphetamine withdrawal symptoms. No medication is effective for treatment of amphetamine

Inhalant withdrawal symptoms have previously been described but not well documented. This case-series describes the sociodemographic and clinical characteristics of nine children and adolescents with gasoline abuse. Gasoline inhalation was the drug of choice in our patients. The mean age was 13.6 years and all the subjects belonged to low socioeconomic status. Most of the subjects used daily and all subjects reported alcohol abuse in the father. All subjects reported a syndrome of intoxication as described in previous reports. All subjects also reported a withdrawal syndrome including irritability, psychomotor retardation, anhedonia, dry mouth, sleep disturbances, craving, and increased lacrimation.

In this study, we investigated the relationships between observed social withdrawal (Positive and Negative Syndrome Scale [PANSS] Passive Social Withdrawal and PANSS Active Social Avoidance), subjectively experienced social withdrawal (Social Functioning Scale [SFS] Withdrawal and SFS Interpersonal Behavior), and their associations to the underlying psychological patterns of Object Relations and Reality Testing. Patients with schizophrenia (n = 55) and bipolar disorder (n = 51) from the ongoing Thematically Organized Psychosis project, Oslo University Hospital, Norway, were evaluated using the Bell Object Relations and Reality Testing Inventory, the PANSS, and the SFS. Object relations and reality testing subscales related differentially to PANSS Passive Social Withdrawal and PANSS Active Social Avoidance. These two measures, together with the level of alienation, explained a significant amount of variance in self-experienced social dysfunction. Findings reveal the multidimensional nature of social dysfunction in severe mental disorders.

The Clinical Institute Withdrawal Assessment-Alcohol, Revised (CIWA-Ar) is an assessment tool used to quantify alcohol withdrawal syndrome (AWS) severity and inform benzodiazepine treatment for alcohol withdrawal. To evaluate the prescribing patterns and appropriate use of the CIWA-Ar protocol in a general hospital setting, as determined by the presence or absence of documented AWS risk factors, patients' ability to communicate, and provider awareness of the CIWA-Ar order. This retrospective chart review included 118 encounters of hospitalized patients placed on a CIWA-Ar protocol during one year. The following data were collected for each encounter: patient demographics, admitting diagnosis, ability to communicate, and admission blood alcohol level; and medical specialty of the clinician ordering CIWA-Ar, documentation of the presence or absence of established AWS risk factors, specific parameters of the protocol ordered, service admitted to, provider documentation of awareness of the active protocol within 48 h of initial order, total benzodiazepine dose equivalents administered and associated adverse events. 57% of patients who started on a CIWA-Ar protocol had either zero or one documented risk factor for AWS (19% and 38% respectively). 20% had no documentation of recent alcohol use. 14% were unable to communicate. 19% of medical records lacked documentation of provider awareness of the ordered protocol. Benzodiazepine associated adverse events were documented in 15% of encounters. The judicious use of CIWA-Ar protocols in general hospitals requires mechanisms to ensure assessment of validated alcohol withdrawal risk factors, exclusion of patients who cannot communicate, and continuity of care during transitions.

Synthetic cathinones have been markedly present in the Spanish drug market in recent years. These substances can be easily obtained in "smart shops", smoke shops, gas stations and web sites where they can be bought and received anonymously avoiding normal law controls. For the first time we present a case of a neonatal withdrawal syndrome in a baby born to a woman who was a chronic consumer of 4-methylethcathinone. The newborn presented with increased jitteriness and irritability, highpitched cry, hypertonia in the limbs and brisk tendon reflexes. 4-Methylethcathinone was identified and quantified by liquid chromatography tandem mass spectrometry in the four subsequent 3cm segments of maternal hair (4.3, 4.0, 4.0 and 3.9ng/mg hair starting from most proximal segment) accounting for maternal consumption during the whole pregnancy and before and in neonatal meconium (0.7ng/g) confirming fetal exposure during intrauterine life. Methadone and its metabolite were also measured in maternal and neonatal matrices. Counseling pregnant women and women who may become pregnant on the consequences of fetal drug exposure to new designer drugs like 4-methylethcathinone is critical to preventing poor neonatal outcomes. This case report is informative to those studying designer drugs and those clinically involved with pregnant women abusing psychoactive substances. Copyright © 2014 Elsevier Ireland Ltd.

Objective: To observe the effect of L-type calcium channel blocker like nimodipine on morphine's withdrawal when it was administered continuously along with morphine versus a single bolus dose of nimodipine, which was administered at the end of the experiment before the precipitation of withdrawal reaction in morphine-dependent rats. Materials and Methods: Four groups of adult male Wistar rats were rendered morphine dependent by subcutaneous injections of morphine at a dose of 10 mg/kg for 10 days. Nimodipine 10 mg/kg intraperitoneally (ip) administered to one group once daily before morphine administration in the entire experimental period, and another group received nimodipine only once at the end of the experiment as a single bolus dose 2 mg/kg before the administration of naloxone. Naloxone 3 mg/kg was administered ip to all the groups to precipitate withdrawal reactions. The withdrawal reactions were evaluated and scored as per the Gellert and Holtzman global withdrawal rating scale. Results: Nimodipine when administered as a single bolus dose before naloxone administration in morphine-dependant rats reduced the features of withdrawal reactions more effectively than continuous administration of nimodipine along with morphine throughout the experimental period. Conclusion: We discovered that nimodipine helps in attenuating the severity of morphine withdrawal having potential role encountered during pharmacotherapy with morphine management of opioid dependence, well memory, impairement, cell signaling and phosphorylation of neuron.

Cannabis withdrawal has not been studied in adults with attention-deficit/hyperactivity disorder (ADHD) who have high rates of cannabis use. We aimed to describe cannabis withdrawal, motivations to quit, and strategies to quit cannabis use in cannabis-dependent adults with ADHD. Twenty-three adults with ADHD enrolled in a controlled clinical trial of pharmacotherapy (atomoxetine) for cannabis dependence (DSM-IV criteria) completed the Marijuana Quit Questionnaire (MJQQ) to provide information on their "most serious" quit attempt made without formal treatment. The study was conducted between November 2005 and June 2008. Participants were predominantly male (82.6%, n = 19), with a mean (SD) age of 27.4 (8.5) years (range, 18-53) at the start of their index quit attempt. The most common motive for quitting cannabis was "to save money" (87%, n = 20); the most common strategy to maintain abstinence was "stopped associating with people who smoke marijuana" (43%, n = 10). Almost all (96%, n = 22) subjects reported ≥ 1 cannabis withdrawal symptom; 7 (30%) met DSM-5 diagnostic criteria for cannabis withdrawal syndrome. Participants with comorbid ADHD and cannabis dependence reported withdrawal symptoms similar to other samples of non-treatment-seeking cannabis-dependent adults with no psychiatric comorbidity. These findings suggest that ADHD does not influence cannabis withdrawal in the way that it does tobacco (nicotine) withdrawal.

Confirmatory factor analysis (CFA) was used to test the hypothesis that the components of the metabolic syndrome are manifestations of a single common factor. Three different datasets were used to test and validate the model. The Spanish and Mauritian studies included 207 men and 203 women and 1,411 men and 1,650 women, respectively. A third analytical dataset including 847 men was obtained from a previously published CFA of a U.S. population. The one-factor model included the metabolic syndrome core components (central obesity, insulin resistance, blood pressure, and lipid measurements). We also tested an expanded one-factor model that included uric acid and leptin levels. Finally, we used CFA to compare the goodness of fit of one-factor models with the fit of two previously published four-factor models. The simplest one-factor model showed the best goodness-of-fit indexes (comparative fit index 1, root mean-square error of approximation 0.00). Comparisons of one-factor with four-factor models in the three datasets favored the one-factor model structure. The selection of variables to represent the different metabolic syndrome components and model specification explained why previous exploratory and confirmatory factor analysis, respectively, failed to identify a single factor for the metabolic syndrome. These analyses support the current clinical definition of the metabolic syndrome, as well as the existence of a single factor that links all of the core components.

Craving and nicotine withdrawal syndrome (NWS) are components of the tobacco use disorder in DSM-5. They both appear after smoking cessation or an abrupt reduction in tobacco use, and they are associated with both short and long-term smoking-cessation outcomes. The aim of the present study was to examine the association of craving and withdrawal with smoking cessation at the end of the treatment and relapse at 3 months follow-up in a Spanish sample of smokers. The sample comprised 342 smokers (37.7% men; 62.3% women) receiving a cognitive-behavioral treatment for smoking cessation. The assessments of craving and withdrawal were conducted using the Minnesota Nicotine Withdrawal Scale. Abstainers at the end of the treatment, compared to non abstainers, showed significantly lower post-treatment withdrawal, and post-treatment craving. Furthermore, they had lower scores in pre-treatment nicotine dependence. Among abstainers, craving decreased significantly from pre-cessation levels, while in those participants who did not quit smoking it remained on the same levels. High nicotine dependence was a predictor of smoking at the end of the treatment, whereas high nicotine withdrawal predicted relapse at 3 months. Findings support the robust role of craving and NWS in smoking cessation and relapse, although they differ in their specific patterns of change over time.

Amphetamine withdrawal has been less studied although it is a common problem with a prevalent rate of 87% among amphetamine users. Its symptoms, in particular intense craving, may be a critical factor leading to relapse of amphetamine use. In clinical practice, treatment for cocaine withdrawal has been recommended for the management of amphetamine withdrawal although the pharmacodynamic and pharmacokinetic properties of these two substances are not the same. To search and determine risks, benefits, and costs of a variety of treatments for the management of amphetamine withdrawal. Electronic searches of MEDLINE (1966 - December 2000), EMBASE (1980 - February 2001), CINAHL (1982 - January 2001) and Cochrane Controlled Trials Register (Cochrane Library 2000 issue 4) were undertaken. References to the articles obtained by any means were searched. All relevant randomised controlled trials (RCTs) and controlled clinical trials (CCTs) were included. Participants were people with amphetamine withdrawal, diagnosed by any set of criteria. Any kinds of biological and psychological treatments both alone and combined were examined. A variety of outcomes, for example, number of treatment responders, score changes, were considered. Two reviewers evaluated and extracted the data independently. The dichotomous data were extracted on an intention-to-treat basis in which the dropouts were assigned as participants with the worst outcomes. The Relative Risk (RR) with the 95% confidence interval (95% CI) was used to assess the dichotomous data. The Weighted Mean Difference (WMD) with 95% CI was used to assessed the continuous data. The results of two studies have shown some benefits of amineptine in the treatment of amphetamine withdrawal. Those benefits can be seen in the respects of discontinuation rate and global state, as measured by Clinical Global Impression Scale. However, no direct benefit of amineptine on amphetamine withdrawal symptoms or craving was shown. The evidence about

This case report describes the development of withdrawal from phenibut, a gamma-aminobutyric acid-receptor type B agonist. Although phenibut is not an FDA-approved medication, it is available through online retailers as a nootropic supplement. There are reports of dependence in patients that misuse phenibut. We report a case in which a patient experienced withdrawal symptoms from phenibut and was successfully treated with a baclofen taper. This case report highlights the development of phenibut use disorder with coingestion of alcohol and potential management for phenibut withdrawal. We believe clinicians must be aware of how phenibut dependence may present and how to manage the withdrawal syndrome.

To compare the ovarian response to early versus late clomiphene citrate (CC) in women with polycystic ovary syndrome (PCOS). This cross-over randomized controlled clinical trial included 90 infertile amenorrheic women with PCOS. After inducing withdrawal bleeding, patients were randomly divided into two equal groups to receive ovulation induction with CC 100 mg/day for 5 days. Group I started treatment the next day after finishing medroxyprogesterone acetate course for a menstrual cycle, and after a washout period of another menstrual cycle, the treatment was shifted to start on day 2 of withdrawal bleeding. Group II received a reversed protocol: late then early treatment. Women were followed up on transvaginal ultrasonography to monitor follicular growth, endometrial thickness and evidence of ovulation. Human chorionic gonadotropin 10 000 IU was given i.m. to trigger ovulation when at least one mature follicle measured ≥18 mm at day 14. In all cases, early induction protocol resulted in significantly higher proportion of ovulating patients, thicker endometrium and higher number of follicles 14-17 mm in diameter, ≥ 18 mm in diameter and total number of follicles (P < 0.001 for all comparisons). In women with PCOS, early initiation of CC before withdrawal bleeding or during the last days of the luteal phase can achieve a better ovulatory response. © 2016 Japan Society of Obstetrics and Gynecology.

There are no data on the incidence of admissions associated with alcohol withdrawal syndrome (AWS) or about its trend over time in Spain. To analyze the characteristics, incidence rates and trends over time of hospital admissions associated with AWS in Spanish public hospitals. Analysis from the Spanish public hospitals minimum basic data set of hospital admissions with AWS (CIE9-MC 291.81), alcohol withdrawal delirium (CIE9-MC 291.0) and alcohol withdrawal hallucinosis (CIE9-MC 291.3), since 1999 to 2010. We identified 56,395 admissions associated with AWS. Mean age was 50.9 (SD 12.5) and 88% were male. The most frequent admission department was Internal Medicine (24.9%). The mean hospital stay was 12.6 days (SD 14.4) and mortality was 4.7%; 62.6% of cases developed AWS during an admission for another reason, mostly due to alcohol-related pathologies. Secondary diagnoses in patients hospitalized for AWS were related to alcohol consumption in more than half of the cases. The incidence rate of admissions associated with AWS in Spain remained stable from 1999 to 2010, with a small decline in the last 3 years of the period. The communities with the highest incidence were the Canary Islands, the Balearic Islands and Galicia. The incidence rate of admissions associated with AWS in Spanish public hospitals in the period 1999-2010 has remained stable with slight changes. There are differences in the incidence of AWS among the different autonomous communities. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Anxiety is one of the early symptoms of opioid withdrawal and contributes to continued drug use and relapse. The acoustic startle response (ASR) is a component of anxiety that has been shown to increase during opioid withdrawal in both humans and animals. We investigated the role of corticotropin-releasing factor (CRF) and norepinephrine (NE), two key mediators of the brain stress system, on acute heroin withdrawal-potentiated ASR. Rats injected with heroin (2 mg/kg s.c.) displayed an increased ASR when tested 4 h after heroin treatment. A similar increase in ASR was found in rats 10-20 h into withdrawal from extended access (12 h) to i.v. heroin self-administration, a model that captures several aspects of heroin addiction in humans. Both the α 2 adrenergic receptor agonist clonidine (10 μg/kg s.c.) and CRF1 receptor antagonist N,N-bis(2-methoxyethyl)-3-(4-methoxy-2-methylphenyl)-2,5-dimethyl-pyrazolo[1,5-a] pyrimidin-7-amine (MPZP; 20 mg/kg s.c.) blocked heroin withdrawal-potentiated startle. To investigate the relationship between CRF1 and α 2 adrenergic receptors in the potentiation of the ASR, we tested the effect of MPZP on yohimbine (1.25 mg/kg s.c.)-potentiated startle and clonidine on CRF (2 μg i.c.v.)-potentiated startle. Clonidine blocked CRF-potentiated startle, whereas MPZP partially attenuated but did not reverse yohimbine-potentiated startle, suggesting that CRF may drive NE release to potentiate startle. These results suggest that CRF1 and α 2 receptors play an important role in the heightened anxiety-like behaviour observed during acute withdrawal from heroin, possibly via CRF inducing the release of NE in stress-related brain regions.

Leukemia inhibitory factor influences the timing of programmed synapses withdrawal from neonatal muscles.

PubMed

Kwon, Y W; Abbondanzo, S J; Stewart, C L; Gurney, M E

1995-09-01

We show that leukemia inhibitory factor (LIF) plays a physiological role in the programmed withdrawal of synapses from neonatal muscles. First, LIF mRNA is present in embryonic skeletal muscle and is developmentally regulated. We detect high levels of LIF mRNA at embryonic day 17 (E17) in mouse hind leg muscles. The content of LIF mRNA falls 10-fold between E17 and birth and then remains low in the neonate and adult. The decrease in LIF mRNA in skeletal muscle coincides with the end of secondary myogenesis and the completion of the adult number of myofibers. Second, treatment of the mouse tensor fascia latae (TFL), a superficial muscle of the hind leg, with LIF from birth (100 ng/day), transiently delays the withdrawal of excess inputs from polyneuronally innervated myofibers by approximately 3 days. The midpoint of the process is shifted from 7.5 +/- 10.2 +/- 0.6 days of age. LIF treatment delays synapse withdrawal by altering its timing without an appreciable effect on its rate. Third, in mice homozygous for a disruption of the LIF gene, the midpoint in the reduction of multiply innervated TFL myofibers occurs 1 day earlier, at 6.5 +/- 0.5 days of age. Muscle fiber number is unchanged in LIF null mice. Treatment with LIF does not alter the rate of neonatal growth, the number of muscle fibers in the TFL, or the reappearance of inputs that have been eliminated. Instead, LIF appears to delay maturation of the motor unit by transiently delaying the onset of synapse withdrawal. We hypothesize that this is a necessary component of a selective process that will operate simultaneously and equally on multiple, competing motor units.

Caffeine Withdrawal and Dependence: A Convenience Survey Among Addiction Professionals.

2013-06-01

Caffeine withdrawal was included in the research appendix of the DSM-IV to encourage additional research to assist with determining its status for the next version of the manual. Caffeine dependence was not included because of a lack of empirical research at the time of publication. This study assessed the beliefs of addiction professionals about the clinical importance of caffeine withdrawal and dependence. A 6-item survey was developed and delivered electronically to the members of six professional organizations that focus on addiction. Open-ended comments were also solicited. Five hundred members responded. The majority (95%) thought that cessation of caffeine could produce a withdrawal syndrome, and that caffeine withdrawal can have clinical importance (73%); however, only half (48%) thought that caffeine withdrawal should be included in the Diagnostic and Statistical Manual of Mental Disorders (DSM). A majority (58%) believed that some people develop caffeine dependence; however, only 44% indicated that it should be in the DSM. Comments suggested that trepidation about inclusion of caffeine diagnoses was due to the concerns about the field of psychiatry being criticized for including common disorders with a relatively low clinical severity. Others, however, expressed an urgent need to take caffeine-related problems more seriously. The majority of addiction professionals believe that caffeine withdrawal and dependence disorders exist and are clinically important; however, these professionals are divided in whether caffeine withdrawal and dependence should be included in DSM. Wider dissemination of the extant literature on caffeine withdrawal and additional research on caffeine dependence will be needed to provide additional guidance to policymakers and healthcare workers.

Peptidase inhibitors reduce opiate narcotic withdrawal signs, including seizure activity, in the rat.

PubMed

Pinsky, C; Dua, A K; LaBella, F S

1982-07-15

Narcotic withdrawal was precipitated by administration of naloxone in a low dose at 2 h after the final dose of morphine in a 9-day dependency-inducing schedule. Withdrawal was characterized by leaps, increased nocifensor activity and by cerebral cortical epileptiform activity, the latter not generally reported to be prominent in narcotic withdrawal. Single large doses of morphine did not provoke epileptiform activity at 2 h postinjection but did induce an acute opioid dependency wherein a moderately high dose of naloxone, ineffective in non-dependent rats, provoked upward leaping and electrocortical epileptiform activity. Pretreatment of the 9-day dependent rats with peptidase inhibitors, administered intracerebroventricularly, significantly reduced withdrawal severity including the epileptiform activity. We propose that peptidase inhibitors protect certain species of endogenous opioids and/or other neuropeptides that tend to suppress expression of the narcotic withdrawal syndrome. Furthermore, our findings suggest that epileptiform activity is a nascent form of cerebral activity hitherto largely unnoticed in narcotic withdrawal and that neuropeptides may be involved in certain epileptic states.

Smoking cessation exhibits an aversive withdrawal syndrome characterized by both increases in somatic signs and affective behaviors including anxiety and depression. In present study, abrupt withdrawal of daily nicotine injections (2mg/kg, s.c., four times daily, for 10 days) significantly increased somatic signs viz. rearing, grooming, jumping, genital licking, leg licking, head shakes with associated depression (increased immobility in forced swim test) as well as anxiety (decreased the number of entries and time spent in open arm in elevated plus maze) in nicotine dependent animals. The peak effect was observed at 24h time point of nicotine withdrawal. Repeated administration of agmatine (40-80µg/mouse, i.c.v.) before the first daily dose of nicotine from day 5 to 10 attenuated the elevated scores of somatic signs and abolished the depression and anxiety like behavior induced by nicotine withdrawal in dependent animals. However, in separate groups, its acute administration 30min before behavior analysis of nicotine withdrawal was ineffective. This result clearly shows the role of agmatine in development of nicotine dependence and its withdrawal. In extension to behavioral experiments, brain agmatine analyses, carried out at 24h time point of nicotine withdrawal demonstrated marked decrease in basal brain agmatine concentration as compared to control animals. Taken together, these data support the role of agmatine as common biological substrate for somatic signs and affective symptoms of nicotine withdrawal. This data may project therapies based on agmatine in anxiety, depression and mood changes associated with tobacco withdrawal. Copyright © 2015 Elsevier B.V. All rights reserved.

Social withdrawal should not be considered a direct measure of the negative symptoms of schizophrenia as it may result not only from asociality (primary negative symptom) but also from other altered processes such as anxiety. To understand the contribution of these two factors to social deficit, we investigated whether the social withdrawal observed in the subchronic phencyclidine (PCP) rat model of schizophrenia could be attributed to increased anxiety. Compared to saline controls, PCP-treated rats (5 mg/kg, twice daily for 7 days, followed by a washout period) spent significantly less time in social interaction, but did not show anxiety-like behaviors in different relevant behavioral paradigms. In addition, their social deficit was not affected by a behavioral procedure known to reduce anxiety-like behavior (repeated exposure to the same partner) nor by systemic administration of the classical anxiolytic diazepam. In contrast, PCP-induced social withdrawal was reversed by the cannabinoid agonist CP55,940, a drug with known anxiogenic properties. Furthermore, when using the social approach task, PCP-treated animals performed similarly to control animals treated with diazepam, but not to those treated with the anxiogenic compound pentylenetetrazole. Taken together, our results indicate that PCP-induced social withdrawal cannot be attributed to increased anxiety. These data are discussed in the context of primary versus secondary negative symptoms and the deficit syndrome of schizophrenia.

To investigate whether, in the treatment with chlordiazepoxide for outpatient alcohol withdrawal, there are advantages of symptom-triggered self-medication over a fixed-schedule regimen. A randomized controlled trial in outpatient clinics for people suffering from alcohol dependence (AD) and alcohol-related problems; 165 adult patients in an outpatient setting in a specialized alcohol treatment unit were randomized 1:1 to either a symptom-triggered self-medication or tapered dose, using chlordiazepoxide. Alcohol withdrawal symptoms, amount of medication, duration of symptoms, time to relapse and patient satisfaction were measured. Patients assessed their symptoms using the Short Alcohol Withdrawal Scale (SAWS). Patient satisfaction was monitored by the Diabetes Treatment Satisfaction Questionnaire. We used the Well-Being Index and the European addiction severity index for the 1-year follow-up. We found no differences in the quantity of medication consumed, time to relapse, well being or treatment satisfaction. Symptom-triggered self-medication was as safe as fixed-schedule medication in treating outpatients with AD and mild to moderate symptoms of AWS. The SAWS is a powerful monitoring tool, because it is brief and permits the subject to log the withdrawal symptoms.

Alcoholism is a complex disorder with genetic and environmental risk factors. The presence of withdrawal symptoms is one criterion for alcohol dependence. Genetic animal models have followed a reductionist approach by quantifying various effects of ethanol withdrawal separately. Different ethanol withdrawal symptoms may have distinct genetic etiologies, and therefore differentiating distinct neurobiological mechanisms related to separate signs of withdrawal would increase our understanding of various aspects of the complex phenotype. This study establishes motor incoordination as a new phenotype of alcohol withdrawal in mice. Mice were made physically dependent on ethanol by exposure to ethanol vapor for 72 h. The effects of ethanol withdrawal in mice from different genetic backgrounds were measured on the accelerating rotarod, a simple motor task. Ethanol withdrawal disrupted accelerating rotarod behavior in mice. The disruptive effects of withdrawal suggest a performance rather than a learning deficit. Inbred strain comparisons suggest genetic differences in magnitude of this withdrawal phenotype. The withdrawal-induced deficits were not correlated with the selection response difference in handling convulsion severity in selectively bred Withdrawal Seizure-Prone and Withdrawal Seizure-Resistant lines. The accelerating rotarod seems to be a simple behavioral measure of ethanol withdrawal that is suitable for comparing genotypes. PMID:18690115

[Psychoanalytic study of social withdrawal: grandiose narcissism and passive aggression due to insufficient maternal containing in childhood].

PubMed

Ogawa, Toyoaki

Two different types of pathology can cause social withdrawal: the narcissistic--schizoid personality organization (NSPO) type and the mild Asperger's syndrome (mild developmental disorders) type. Only the former type can be treated by psychoanalytic psychotherapy. In the childhood of both types, one may find traumatic family environments which will result in social withdrawal (Hikikomori). In the infancy of the NSPO type, the mother fails to function as a sufficient container of the child's emotion, which encourages formation of a schizoid personality organization i.e. the psychic withdrawal (or "psychic retreat" by Steiner, J.). With only a little failure in life events, this may turn into a physical withdrawal for a long time. And in this type of pathology their aggression takes a passive form that hardens their social withdrawal situation. Moreover, the social withdrawal itself serves to reinforce the pathological narcissism.

Neurotrophins, brain-derived neurotrophic factors (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4), have been implicated in the modulation of heroin dependency. This study was designed to explore the expression alterations of BDNF, NT-3, and NT-4 in the context of heroin dependence and withdrawal in the rat nucleus accumbens (NAc). Heroin dependence was induced by a progressive intraperitoneal treatment of heroin. The results showed that the expression levels of BDNF and NT-4 were significantly decreased in the NAc of rats with heroin addiction in comparison with the control group, whereas there was a significant increase in BDNF and NT-4 expressions in the groups of rats with both naloxone-induced and spontaneous withdrawal. Moreover, NT-3 expression was markedly increased in the NAc of rats with heroin addiction and spontaneous withdrawal in comparison with the control group, but decreased in the NAc of rats with naloxone-induced withdrawal. These results indicated that chronic administration of heroin results in the alterations of BDNF, NT-3, and NT-4 expressions in the rat NAc. BDNF, NT-3, and NT-4 may play a critical role in the development of heroin dependency and withdrawal.

Rates of marijuana use among detained youths are exceptionally high. Research suggests a cannabis withdrawal syndrome is valid and clinically significant; however, these studies have mostly been conducted in highly controlled laboratory settings with treatment-seeking, White adults. The present study analyzed archival data to explore the magnitude of cannabis withdrawal symptoms within a diverse sample of detained adolescents while controlling for tobacco use and investigating the impact of race on symptom reports. Adolescents recruited from a juvenile correctional facility (N=93) completed a background questionnaire and the Marijuana Withdrawal Checklist. Analyses revealed a significant main effect for level of tobacco use on severity of irritability, and for level of marijuana use on severity of craving to smoke marijuana and strange/wild dreams. Furthermore, a significant main effect for race was found with Black adolescents reporting lower withdrawal discomfort scores and experiencing less severe depressed mood, difficulty sleeping, nervousness/anxiety, and strange/wild dreams. Although exploratory, these findings may have significant clinical implications for providers in juvenile detention facilities, allowing the execution of proper medical and/or behavioral interventions to assist adolescents presenting with problematic cannabis and/or tobacco withdrawal.

To determine risk factors associated to Burnout Syndrome in medical gynecologist staff who works at the Gynecology-pediatrics with Family Medicine Hospital number 31 of the IMSS at Mexicali city, Baja California. A cross sectional study was performed in 27 gynecologists (100% of the total gynecologist that works at that particular hospital). A validated survey instrument developed by Maslach was applied to them in order to identify the presence of the syndrome and a general questionnaire including sociodemographic information was also applied to the doctors. The statistical analysis was both descriptive and inferential including chi square, Student t and logistic regression. 74.1% of the doctors who showed signs of Burnout Syndrome were males and 25.9% were females. The average doctors age of the group who developed Burnout was 44.81 +/- 6.11 years. The mean time in years of work for the doctors with the syndrome was 15.56 +/- 7.11 years. Only one doctor was divorced and she presented Burnout Syndrome, on the other hand, 62.5% of the married doctors showed evidence of Burnout Syndrome (p > 0.05). The general prevalence was 59.2%. Of those who showed signs of burnout, 87.5% presented it in low degree, 6.2% presented moderate degree, 6.2% presented high burnout degree. Out of all the organizational factors type, none resulted significative. The prevalence of the reported syndrome is apparently high when compared to the medical anesthesiology staff of the same hospital; however this difference is not statistically significative. In the unvaried and multivariate analyses, no organizational factor shows significance as a potential risk. It is necessary to consider psychological support to the affected doctors and to value the organization of the service, looking for an administrative reengineering.

Prevalence of cigarette smoking among opioid-dependent individuals is 6-fold that of the general U.S. adult population and their quit rates are notoriously poor. One possible reason for the modest cessation outcomes in opioid-dependent smokers may be that they experience more severe tobacco withdrawal upon quitting. In this secondary analysis, we evaluated tobacco withdrawal in opioid-dependent (OD) smokers versus smokers without co-occurring substance use disorders (SUDs). Participants were 47 methadone- or buprenorphine-maintained smokers and 25 non-SUD smokers who completed 1 of several 2-week studies involving daily visits for biochemical monitoring, delivery of financial incentives contingent on smoking abstinence, and assessment of withdrawal via the Minnesota Nicotine Withdrawal Scale (MNWS). Prior to quitting smoking, OD smokers presented with higher baseline withdrawal scores than non-SUD smokers (1.7 ± 0.2 vs. 0.7 ± 0.2, respectively; F [1, 63] = 7.31, p < .001). Withdrawal scores in both groups decreased over the subsequent 2-week period with no group differences, F (1, 910) = 0.50, p = .48. A similar pattern was observed on craving (i.e., Desire to Smoke item of MNWS), although the trajectory of decrease over time on this item was also moderated by gender. Overall, there was no difference in withdrawal during biochemically verified smoking abstinence between OD and non-SUD smokers, suggesting that elevated withdrawal severity following quitting may not be a major factor contributing to the poor cessation outcomes consistently observed among OD smokers. Further scientific efforts are needed to improve our understanding of the high smoking rates and modest cessation outcomes in this challenging population.

The dorsal striatum has been proposed to contribute to the formation of drug-seeking behaviors, leading to excessive and compulsive drug usage, such as addiction. The current study aimed to investigate the involvement of extracellular signal-regulated kinase (ERK) pathway in the modification of striatal synaptic plasticity. Ethanol was administered to rats in drinking water at concentration of 6% (v/v) for 30 days. Rats were sacrificed on day 10, 20, or 30 during ethanol intake or on withdrawal day 1, 3, or 7 following 30-d ethanol intake. The striata were removed either for electrophysiological recording or for protein immuno-blot analysis. Extracellular recording technique was used to record population spikes (PS) induced by high-frequency stimulation (HFS) in the dorsolateral striatum (DLS). Corticostriatal long-term depression (LTD) was determined to be dependent upon ERK signaling. Chronic ethanol intake (CEI) attenuated ERK phosphorylation and LTD induction, whereas withdrawal for one day (W1D) potentiated ERK phosphorylation and LTD induction. These results showed that the impact of chronic ethanol intake and withdrawal on corticostriatal synaptic plasticity was associated with ethanol's effect on ERK phosphorylation. In particular, pharmacological inhibition of ERK hyper-phosphorylation by U0126 prevented LTD induction in the DLS and attenuated ethanol withdrawal syndrome as well. In rat DLS, chronic ethanol intake and withdrawal altered LTD induction via ERK signaling pathway. Ethanol withdrawal syndrome is mediated, at least partly, by ERK hyper-phosphorylation in the DLS.

We present a descriptive, retrospective study of initial symptoms, comorbidity, and alcohol withdrawal in 73 alcoholic patients with subsequent Korsakoff syndrome. In 25/73 (35%) of the patients the classic triad of Wernicke's encephalopathy with ocular symptoms, ataxia and confusion, was found. In at least 6/35 (17%) of the initial deliria (95% confidence interval: 10-25%) we observed no other underlying causes, thus excluding other somatic causes, medication, (recent) alcohol withdrawal, or intoxication. We suggest that these deliria may have been representing Wernicke's encephalopathy. A high frequency (15%) of diabetics may reflect a contributing factor of diabetes mellitus in the evolution of the Wernicke-Korsakoff syndrome. Copyright © American Academy of Addiction Psychiatry.

NTDs associated with syndromes, disorders, and maternal risk factors are a rare but important cause of NTDs. The recurrence risk and the preventive effect of maternal folic acid intake in NTDs associated with syndromes, disorders, and maternal risk factors may be different from those of non-syndromic multifactorial NTDs. Perinatal identification of NTDs should alert one to the syndromes, disorders, and maternal risk factors associated with NTDs, and prompt a thorough etiologic investigation and genetic counseling.

Alcohol withdrawal syndrome (AWS) is a potentially fatal outcome of severe alcohol dependence that presents a significant challenge to treatment. Although AWS is thought to be driven by a hyperglutamatergic brain state, benzodiazepines, which target the GABAergic system, comprise the first line of treatment for AWS. Using a rat model of ethanol withdrawal, we tested whether ceftriaxone, a β-lactam antibiotic known to increase the expression and activity of glutamate uptake transporter EAAT2, reduces the occurrence or severity of ethanol withdrawal manifestations. After a 2-week period of habituation to ethanol in two-bottle choice, alcohol-preferring (P) and Wistar rats received ethanol (4.0 g/kg) every 6 h for 3–5 consecutive days via gavage. Rats were then deprived of ethanol for 48 h during which time they received ceftriaxone (50 or 100 mg/kg, IP) or saline twice a day starting 12 h after the last ethanol administration. Withdrawal manifestations were captured by continuous video recording and coded. The evolution of ethanol withdrawal was markedly different for P rats vs Wistar rats, with withdrawal manifestations occurring >12 h later in P rats than in Wistar rats. Ceftriaxone 100 mg/kg per injection twice per day (200 mg/kg/day) reduced or abolished all manifestations of ethanol withdrawal in both rat variants and prevented withdrawal-induced escalation of alcohol intake. Finally, ceftriaxone treatment was associated with lasting upregulation of ethanol withdrawal-induced downregulation of EAAT2 in the striatum. Our data support the role of ceftriaxone in alleviating alcohol withdrawal and open a novel pharmacologic avenue that requires clinical evaluation in patients with AWS. PMID:24452391

Although negative symptoms are a barrier to recovery from schizophrenia, little is understood about the psychological processes that reinforce and sustain them. To explore this issue, this study used structural equation modeling to test whether the impact of social withdrawal and emotion recognition deficits upon negative symptoms is mediated by the richness or poverty of personal narratives. The participants were 99 adults with schizophrenia spectrum disorders. Social cognition was assessed using the Bell-Lysaker Emotional Recognition Task; social withdrawal, using the Quality of Life Scale; narrative coherence, using the Scale To Assess Narrative Development; and negative symptoms, using the Positive and Negative Syndrome Scale. The findings reveal that although social cognition deficits and social withdrawal are significantly associated with negative symptom severity, these relationships become nonsignificant when personal narrative integrity is examined as a mediating factor. These results indicate that the development of personal narratives may be directly linked to the severity of negative symptoms; this construct may be a useful target for future interventions.

Excessive alcohol consumption, a major health problem worldwide, affects about 6% of the United States population. Caring for patients with alcohol withdrawal syndrome in a hospital ward presents complex physiologic and psycho-social challenges which are best met with evidence-based practices. An academic medical center in the United States has been experiencing an increase in patients with alcohol withdrawal syndrome. However, gaps in clinician knowledge and infrastructure supporting the management of these patients still existed. The aim of this project was to improve the continuity of care of patients undergoing alcohol withdrawal in a medical surgical high acuity transitional care unit by incorporating evidence-based practices, and thereby to positively impact on patient outcomes. Specific objectives were related to standardized assessments and pharmacologic management strategies. The project used the Joanna Briggs Institute's Practical Application of Clinical Evidence System and Getting Research into Practice audit tool for promoting change in health practice. A baseline clinical audit was conducted to assess compliance with best practices for managing alcohol withdrawal syndrome, which was followed by several interventions targeted at nurses and providers. A follow-up audit was conducted to assess compliance with the implemented strategies. The follow-up audit used the same evidence-based audit criteria as those used for the baseline audit. A non-probabilistic, convenience sampling approach was used. A sample size of 15 patients was used for both the baseline and follow-up audits. The baseline audit revealed a high compliance rate for four of the five audit criteria concerning risk assessment and pharmacologic strategies. There was sub-optimal compliance (53%) with the criterion regarding use of the Clinical Institute Withdrawal Assessment of Alcohol Scale (revised) (CIWA-Ar) scale to assess patients with alcohol withdrawal. After the interventions were

In newly diagnosed patients with Dravet syndrome sodium channel blockers are usually avoided. However, in many adult patients the diagnosis was made long after the initiation of therapy. The purpose of our study was to acquire information concerning the potential risks and benefits of (ox)carba(ma)zepine withdrawal in adult patients with genetically confirmed Dravet syndrome. We identified 16 adults with Dravet syndrome, living in a tertiary care facility for people with epilepsy and an intellectual disability. We reviewed clinical history, genetic findings, the type and duration of sodium channels blockers that were used, seizure types and frequency, and the effect of a change in these medications. The study population consisted of 9 men and 7 women. Median age was 35 years (range 20-61 years). An attempt to withdraw carbamazepine (CBZ) was made in 9 patients. In 3 of these patients an increase in tonic-clonic seizures was observed. An attempt to withdraw oxcarbazepine (OXC) was made in 3 patients, leading to a complete stop in 2 patients. 3 of the 4 deaths in the withdrawal-group were related to epilepsy. In adult patients with Dravet syndrome withdrawal of CBZ or OXC is not without risks. We suggest that (ox)carba(ma)zepine withdrawal should be considered in these patients but only if there is a good reason to do so and only if they are closely monitored.

2010-01-01

Background Anxiety states, including those arising during acute or protracted withdrawal periods, may be precipitating factors in alcoholic relapse. Given the cyclical nature of ethanol withdrawal associated with repeated cycles of ethanol intake and abstinence in a pattern that often spans years, meaningful attempts to model ethanol withdrawal–associated anxiety should incorporate cycled ethanol treatments. The studies reported herein examined the effects of γ-aminobutyric acid–modulating drugs on social interaction behavior—an established model of anxiety—in rats exposed to repeated cycles of ethanol treatment and withdrawal. Methods Rats were exposed to 8 to 12 g/kg/day ethanol during three 7-day dietary cycles (5 days on ethanol diet followed by 2 days on control diet). Ethanol was administered either at hour 4 of withdrawal after cessation of each of the first 2 ethanol cycles or during the final withdrawal only. In other groups, the early withdrawals were treated with alphaxalone, diazepam, PK11159, or flumazenil to block anxiety-like behavior during an untreated later (third) withdrawal. The benzodiazepine inverse agonist DMCM (methyl–6, 7–dymerhoxy–4–ethyl–beta–carboline–3–carboxylate) was also given repeatedly to determine whether it would sensitize anxiety-like behavior during a future withdrawal. Finally, the effects of all drugs on deficits in locomotor behavior were assessed. Results Pretreatment of earlier withdrawals with alphaxalone, diazepam, ethanol, or flumazenil reduced social interaction deficits during a later withdrawal, but pretreatment with PK11195 did not. In contrast, DMCM administered in lieu of early withdrawals increased social interaction deficits during an untreated later withdrawal. Locomotor deficits were significantly reversed only by the acute ethanol and diazepam treatment during the final withdrawal.

Background and Aims Questions over the clinical significance of cannabis withdrawal have hindered its inclusion as a discrete cannabis induced psychiatric condition in the Diagnostic and Statistical Manual of Mental Disorders (DSM IV). This study aims to quantify functional impairment to normal daily activities from cannabis withdrawal, and looks at the factors predicting functional impairment. In addition the study tests the influence of functional impairment from cannabis withdrawal on cannabis use during and after an abstinence attempt. Methods and Results A volunteer sample of 49 non-treatment seeking cannabis users who met DSM-IV criteria for dependence provided daily withdrawal-related functional impairment scores during a one-week baseline phase and two weeks of monitored abstinence from cannabis with a one month follow up. Functional impairment from withdrawal symptoms was strongly associated with symptom severity (p = 0.0001). Participants with more severe cannabis dependence before the abstinence attempt reported greater functional impairment from cannabis withdrawal (p = 0.03). Relapse to cannabis use during the abstinence period was associated with greater functional impairment from a subset of withdrawal symptoms in high dependence users. Higher levels of functional impairment during the abstinence attempt predicted higher levels of cannabis use at one month follow up (p = 0.001). Conclusions Cannabis withdrawal is clinically significant because it is associated with functional impairment to normal daily activities, as well as relapse to cannabis use. Sample size in the relapse group was small and the use of a non-treatment seeking population requires findings to be replicated in clinical samples. Tailoring treatments to target withdrawal symptoms contributing to functional impairment during a quit attempt may improve treatment outcomes. PMID:23049760

Withdrawal from high-carbohydrate, high-saturated-fat diet changes saturated fat distribution and improves hepatic low-density-lipoprotein receptor expression to ameliorate metabolic syndrome in rats.

The "lipid hypothesis" determined that saturated fatty acid (SFA) raises low-density lipoprotein cholesterol, thereby increasing the risk for metabolic syndrome (MetS). The aim of this study was to investigate the effect of subchronic withdrawal from a high-carbohydrate, high-saturated fat (HCHF) diet during MetS with reference to changes in deleterious SFA (C12:0, lauric acid; C14:0, myristic acid; C16:0, palmitic acid; C18:0, stearic acid) distribution in liver, white adipose tissue (WAT), and feces. MetS induced by prolonged feeding of an HCHF diet in Wistar albino rat is used as a model of human MetS. The MetS-induced rats were withdrawn from the HCHF diet and changed to a basal diet for final 4 wk of the total experimental duration of 16 wk. SFA distribution in target tissues and hepatic low-density lipoprotein receptor (LDLr) expression were analyzed. Analyses of changes in SFA concentration of target tissues indicate that C16:0 and C18:0 reduced in WAT and liver after withdrawal of the HCHF diet. There was a significant (P < 0.001) decrease in fecal C12:0 with HCHF feeding, which significantly (P < 0.01) increased after withdrawal of this diet. Also, an improvement in expression of hepatic LDLr was observed after withdrawal of HCHF diet. The prolonged consumption of an HCHF diet leads to increased SFA accumulation in liver and WAT, decreased SFA excretion, and reduced hepatic LDLr expression during MetS, which is prominently reversed after subchronic withdrawal of the HCHF diet. This can contribute to better understanding of the metabolic fate of dietary SFA during MetS and may apply to the potential reversal of complications by the simple approach of nutritional modification.

To broaden existing knowledge of pediatric end-of-life decision making by exploring factors described by parents of patients in the pediatric intensive care unit (PICU) as important/influential if they were to consider withdrawing life-sustaining therapies. Quantitative and qualitative analysis of semi-structured one-on-one interviews. The PICUs at 2 tertiary care hospitals. English- or Spanish-speaking parents who were older than 17 years and whose child was admitted to the PICU for more than 24 hours to up to 1 week. Semi-structured one-on-one interviews. Forty of 70 parents (57%) interviewed said they could imagine a situation in which they would consider withdrawing life-sustaining therapies. When asked if specific factors might influence their decision making, 64% of parents said they would consider withdrawing life-sustaining therapies if their child were suffering; 51% would make such a decision based on quality-of-life considerations; 43% acknowledged the influence of physician-estimated prognosis in their decision; and 7% said financial burden would affect their consideration. Qualitative analysis of their subsequent comments identified 9 factors influential to parents when considering withdrawing life-sustaining therapies: quality of life, suffering, ineffective treatments, faith, time, financial considerations, general rejection of withdrawing life-sustaining therapies, mistrust/doubt toward physicians, and reliance on self/intuition. Parents describe a broad range of views regarding possible consideration of withdrawing life-sustaining therapies for their children and what factors might influence such a decision.

Examination of the psychometric properties of the SOWS included exploratory factor analysis, internal consistency, test-retest reliability, and criterion validity. Exploratory factor analysis of the SOWS revealed a general pattern of four factors with three items not always clustered in the same factors at different points of measurement. After excluding these items from factor analysis four factors were identified during detoxification (temperature dysregulation, tractus locomotorius, tractus gastro-intestinalis and facial disinhibition). The 13-item SOWS shows high internal consistency and test-retest reliability and good validity at different stages of withdrawal. The 13-item SOWS is a reliable and valid instrument to assess opioid withdrawal during rapid detoxification. Three items were deleted because their content does not correspond directly with opioid withdrawal symptoms. Copyright (c) 2007 S. Karger AG, Basel.

Successful treatment of dwarfism secondary to long-term steroid therapy in steroid-dependent nephrotic syndrome.

2010-01-01

Prolonged steroid therapy is generally used for steroid-dependent nephrotic syndrome in pediatric patients. However, dwarfism secondary to a long-term regimen and its successful reverse is rarely reported. The underlying mechanism of dwarfism is still poorly understood, as both long-term steroid use and nephrotic syndrome may interact or independently interfere with the process of growth. Here, we present a 17-year-old patient with dwarfism and steroid-dependent nephrotic syndrome and the successful treatment by recombinant human growth factor and cyclosporine A with withdrawal of steroid. We also briefly review the current understanding and the management of dwarfism in pediatric patients with nephrotic syndrome.

Stories of Hell and Healing: Internet Users' Construction of Benzodiazepine Distress and Withdrawal.

PubMed

Fixsen, Alison M; Ridge, Damien

2017-11-01

Benzodiazepines are a group of drugs used mainly as sedatives, hypnotics, antiepileptics, and muscle relaxants. Consumption is recommended for 2 to 4 weeks only, due to fast onset of dependency and potentially distressing withdrawal symptoms. Few peer-review studies have drawn on the user experiences and language to appreciate firsthand experiences of benzodiazepine withdrawal or discontinuation syndrome. We looked extensively at patient stories of benzodiazepine withdrawal and recovery on Internet support sites and YouTube. Our analysis indicated that users employ rich metaphors to portray the psychologically disturbing and protracted nature of their suffering. We identified seven major themes: hell and isolation, anxiety and depression, alienation, physical distress, anger and remorse, waves and windows, and healing and renewal. By posting success stories, ex-users make known that "healing" can be a long, unpredictable process, but distress does lessen, and recovery can happen.

[Purpose] This study investigated the serologic factors associated with metabolic syndrome and gallstones. [Subjects and Methods] The study evaluated subjects who visited a health promotion center in Seoul from March 2, 2013 to February 28, 2014, and had undergone abdominal ultrasonography. Height, weight, and blood pressure were measured. Blood sampling was performed for high-density lipoprotein cholesterol, triglyceride, fasting blood glucose, total bilirubin, direct bilirubin, indirect bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, uric acid, total cholesterol, low-density lipoprotein cholesterol, thyroid stimulating hormone, and red and white blood cell counts. We conducted logistic regression analysis to assess the risk factors associated with metabolic syndrome. [Results] The risk factors for metabolic syndrome in men, in order of decreasing weight, were red blood cell count, body mass index, maximum size of gallstones, white blood cell count, waist circumference, and uric acid level. The factors in women, in order of decreasing weight, were red blood cell count, presence/absence of gallstones, uric acid level, body mass index, fasting blood glucose, and waist circumference. [Conclusion] Most serum biochemical factors and gallstone occurrence could be used to indicate the presence or absence of metabolic syndrome, independent of gender. PMID:27630427

Cerebral blood flow and oxygen consumption during ethanol withdrawal in the rat.

Hemmingsen, R; Barry, D I; Hertz, M M; Klinken, L

The ethanol withdrawal syndrome in man and animals is characterized by signs of CNS hyperactivity although a direct measurement of a physiological variable reflecting this CNS hyperactivity has never been performed in untreated man or in animals. We induced ethanol dependence in the rat by means of intragastric intubation with a 20% w/v ethanol solution, thus keeping the animals in a state of continuous severe intoxication for 3--4 days; during the subsequent state of withdrawal characterized by tremor, rigidity, stereotyped movements and general seizures a 25% increase in cerebral oxygen consumption (CMRO2) could be measured; this increase was not due to catecholamines originating from adrenal medulla as adrenomedullectomized animals showed a similar increase in CMRO2 (28%); the withdrawing animals showed a corresponding cerebral blood flow (CBF) increase. The elevated CMRO2 and CBF could be reduced to normal by administration of a beta-adrenergic receptor blocker (propranolol 2 mg/kg i.v.), and hence the increased CMRO2 during ethanol withdrawal could be related to catecholaminergic systems in the brain, e.g. the noradrenergic locus coeruleus system which is anatomically well suited as a general activating system. This interpretation is supported by the earlier neurochemical finding of an increased cerebral noradrenaline turnover during ethanol withdrawal. The exact mechanism underlying the increased cerebral oxygen consumption during ethanol withdrawal and the effect of propranolol on cerebral function during this condition remains to be clarified.

Objective To broaden existing knowledge of pediatric end-of-life decision making by exploring factors described by parents of patients in the pediatric intensive care unit (PICU) as important/influential if they were to consider withdrawing life-sustaining therapies. Design Quantitative and qualitative analysis of semi-structured one-on-one interviews. Setting The PICUs at 2 tertiary care hospitals. Participants English- or Spanish-speaking parents who were older than 17 years and whose child was admitted to the PICU for more than 24 hours to up to 1 week. Intervention Semi-structured one-on-one interviews. Results Forty of 70 parents (57%) interviewed said they could imagine a situation in which they would consider withdrawing life-sustaining therapies. When asked if specific factors might influence their decision making, 64% of parents said they would consider withdrawing life-sustaining therapies if their child were suffering; 51% would make such a decision based on quality-of-life considerations; 43% acknowledged the influence of physician-estimated prognosis in their decision; and 7% said financial burden would affect their consideration. Qualitative analysis of their subsequent comments identified 9 factors influential to parents when considering withdrawing life-sustaining therapies: quality of life, suffering, ineffective treatments, faith, time, financial considerations, general rejection of withdrawing life-sustaining therapies, mistrust/doubt toward physicians, and reliance on self/intuition. Conclusion Parents describe a broad range of views regarding possible consideration of withdrawing life-sustaining therapies for their children and what factors might influence such a decision.

Mo, Yoonsun; Thomas, Michael C; Karras, George E

2016-04-01

To perform a systematic review of the clinical trials concerning the use of barbiturates for the treatment of acute alcohol withdrawal syndrome (AWS). A literature search of MEDLINE, EMBASE, and the Cochrane Library, together with a manual citation review was conducted. We selected English-language clinical trials (controlled and observational studies) evaluating the efficacy and safety of barbiturates compared with benzodiazepine (BZD) therapy for the treatment of AWS in the acute care setting. Data extracted from the included trials were duration of delirium, number of seizures, length of intensive care unit and hospital stay, cumulated doses of barbiturates and BZDs, and respiratory or cardiac complications. Seven studies consisting of 4 prospective controlled and 3 retrospective trials were identified. Results from all the included studies suggest that barbiturates alone or in combination with BZDs are at least as effective as BZDs in the treatment of AWS. Furthermore, barbiturates appear to have acceptable tolerability and safety profiles, which were similar to those of BZDs in patients with AWS. Although the evidence is limited, based on our findings, adding phenobarbital to a BZD-based regimen is a reasonable option, particularly in patients with BZD-refractory AWS.

Previous research indicated the complexity of autonomic dysfunction during acute alcohol withdrawal. This study aimed to investigate the pupillary light reflex as an indicator of midbrain and brainstem regulatory systems in relation to cardiovascular autonomic function. Thirty male patients were included in the study. They were investigated during acute alcohol withdrawal syndrome and 24h later during clomethiazole treatment and compared to healthy controls. Parameters of pupillary light reflex of both eyes as well as heart rate variability, blood pressure variability and baroreflex sensitivity (BRS) were studied. We observed significantly reduced sympathetic (small diameter, e.g., left eye: 5.00 in patients vs. 5.91 mm in controls) and vagal modulation (e.g., prolonged latencies, left eye: 0.28 vs. 0.26 ms) regarding both pupils during acute alcohol withdrawal syndrome. Cardiovascular parameters showed reduced vagal modulation (e.g., b-slope of BRS: 7. 57 vs. 13.59 ms/mm Hg) and mixed results for sympathetic influence. After 24h, autonomic dysfunction improved significantly, both for the pupils (e.g., left diameter: 5.38 mm) and the heart (e.g., b-slope of BRS: 9.34 ms/mm Hg). While parameters obtained from the pupil correlated with cardiac autonomic function (e.g, BRS and left diameter: r=0.564) in healthy controls, no such pattern was observed in patients. Results obtained from the pupil during acute alcohol withdrawal do not simply mirror autonomic dysfunction regarding the heart. Pupillary and cardiovascular changes after 24h indicate state dependencies of the results. The findings are discussed with respect to autonomic mechanisms and potentially involved brain regions.

Acute alcohol withdrawal syndrome (AAWS) is encountered in patients presenting acutely to the Emergency Department (ED) and often requires pharmacologic management. We investigated whether a single dose of intravenous (i.v.) phenobarbital combined with a standardized lorazepam-based alcohol withdrawal protocol decreases intensive care unit (ICU) admission in ED patients with acute alcohol withdrawal. This was a prospective, randomized, double-blind, placebo-controlled study. Patients were randomized to receive either a single dose of i.v. phenobarbital (10 mg/kg in 100 mL normal saline) or placebo (100 mL normal saline). All patients were placed on the institutional symptom-guided lorazepam-based alcohol withdrawal protocol. The primary outcome was initial level of hospital admission (ICU vs. telemetry vs. floor ward). There were 198 patients enrolled in the study, and 102 met inclusion criteria for analysis. Fifty-one patients received phenobarbital and 51 received placebo. Baseline characteristics and severity were similar in both groups. Patients that received phenobarbital had fewer ICU admissions (8% vs. 25%, 95% confidence interval 4-32). There were no differences in adverse events. A single dose of i.v. phenobarbital combined with a symptom-guided lorazepam-based alcohol withdrawal protocol resulted in decreased ICU admission and did not cause increased adverse outcomes.

2002-01-01

We report a 50-year-old male patient with a 15-year history of psoriasis including mutilating psoriatic arthritis, in whom the withdrawal of cyclosporin A induced a generalised pustular exacerbation and a aggravation of the joint condition. Two weekly injections of 25 mg of the tumour necrosis factor alpha inhibitor etanercept led to a rapid improvement of his psoriatic arthritis, as well as regression of the pustular eruption, while residual erythema was still present. The clinical response was reflected by an increase in circulating interleukin (IL) 10 and a decrease in IL-6 and IL-8 serum levels during treatment. We conclude that etanercept may be a safe and effective therapy not only in severe psoriatic arthritis, but also in cases of pustular rebound after withdrawal of immunosuppressive agents.

To investigate the relationship between inflammatory factors and two Chinese medicine (CM) syndrome types of qi stagnation and blood stasis (QSBS) and qi deficiency and blood stasis (QDBS) in patients with acute coronary syndrome (ACS). Sixty subjects with ACS, whose pathogenesis changes belongs to qi disturbance blood stasis syndrome, were divided into 2 groups: 30 in the QSBS group and 30 in the QDBS group. The comparative analysis on them was carried out through comparing general information, coronary angiography and inflammatory factors including intracellular adhesion molecule-1 (ICAM-1), chitinase-3-like protein 1 (YKL-40) and lipoprotein-associated phospholipase A2 (Lp-PLA2). Compared with the QSBS group, Lp-PLA2 and YKL-40 levels in the QDBS group showed no-significant difference (P>0.05); ICAM-1 was significantly higher in the QDBS group than in the QSBS group in the pathological processes of qi disturbance and blood stasis syndrome of ACS (P<0.05). Inflammatory factor ICAM-1 may be an objective basis for syndrome typing of QSBS and QDBS, which provides a research direction for standardization research of CM syndrome types.

Posterior reversible encephalopathy syndrome (PRES) after bariatric surgery—a potential consequence associated with rapid withdrawal of antihypertensive medications

2015-01-01

A 61-year-old woman with a medical history of intracerebral haemorrhage, hypertension, hyperlipidaemia and carotid stenosis presented to the emergency department with altered mental status 3 weeks after undergoing a vertical sleeve gastrectomy for severe obesity. She presented with a hypertensive emergency and a National Institutes of Health Stroke Scale of 4. CT of the head was unrevealing. MRI showed an abnormal signal within the bilateral posterior border-zone areas, with several foci in the parietal and occipital lobes, and thalami, suggestive of posterior reversible encephalopathy syndrome (PRES). The patient was initially placed on a labetalol drip and her preoperative antihypertensive medications—amlodipine, captopril, triamterene and hydrochlorothiazide—were gradually reintroduced. She returned to her baseline and was stable on discharge. Rapid withdrawal of antihypertensive medications in the early postoperative period of bariatric surgery was the aetiology of PRES in this patient. This case report discusses postoperative care of bariatric surgery patients having hypertension. PMID:26698202

Heterogeneity and individual differences in the developmental course of social withdrawal were examined longitudinally in a community sample (N=392). General Growth Mixture Modeling (GGMM) was used to identify distinct pathways of social withdrawal, differentiate valid subgroup trajectories, and examine factors that predicted change in trajectories within subgroups. Assessments of individual (social withdrawal), interactive (prosocial behavior), relationship (friendship involvement, stability and quality, best friend’s withdrawal and exclusion/victimization) and group- (exclusion/victimization) level characteristics were used to define growth trajectories from the final year of elementary school, across the transition to middle school, and then to the final year of middle school (fifth-to-eighth grades). Three distinct trajectory classes were identified: low stable, increasing, and decreasing. Peer exclusion, prosocial behavior, and mutual friendship involvement differentiated class membership. Friendlessness, friendship instability, and exclusion were significant predictors of social withdrawal for the increasing class, whereas lower levels of peer exclusion predicted a decrease in social withdrawal for the decreasing class.

2016-11-01

The objective of this study was to estimate the risk of a seizure relapse and the high-risk period of recurrence after antiepileptic drug (AED) withdrawal and to determine the predictive factors for a seizure relapse in adult patients with focal epilepsy who were seizure-free for more than 2years. Using the Wenzhou Epilepsy Follow-Up Registry Database, 200 adult patients with focal epilepsy were recruited, who were undergoing follow-up, met the inclusion criteria of this study, were seizure-free for more than 2years, began withdrawing between June 2003 and June 2014, and were followed up prospectively for at least 1year or until a seizure relapse. The risk of recurrence and the time to seizure relapse were analyzed by the Kaplan-Meier method, and the predictive factors were identified by the Cox proportional hazard regression model. A total of 99 patients had an unprovoked relapse during the follow-up period. The relapse rate was 49.5%, and each year, the recurrence probability of 12, 24, 36, 48, 60, 72, and 84months after AED withdrawal was 24.0%, 20.4%, 8.3%, 2.7%, 4.6%, 0.97%, and 0.98%, respectively. The two independent risk factors for recurrence after withdrawal in adult patients with focal epilepsy were a longer duration of active epilepsy and a shorter seizure-free period before withdrawal. The high-risk period of a seizure relapse in adult patients with focal epilepsy is the first 2years after withdrawal, and beyond 5years after withdrawal, seizures rarely relapse (relapse rate<1%). A seizure-free period for less than 4years before withdrawal is a predictive factor of risk for seizure recurrence after AED withdrawal in adult patients with focal epilepsy.

Risk factors of postthrombotic syndrome before and after deep venous thrombosis treatment.

PubMed

Strijkers, Rob Hw; de Wolf, Mark Af; Wittens, Cees Ha

2017-07-01

Postthrombotic syndrome is the most common complication after deep venous thrombosis. Postthrombotic syndrome is a debilitating disease and associated with decreased quality of life and high healthcare costs. Postthrombotic syndrome is a chronic disease, and causative treatment options are limited. Prevention of postthrombotic syndrome is therefore very important. Not all patients develop postthrombotic syndrome. Risk factors have been identified to try to predict the risk of developing postthrombotic syndrome. Age, gender, and recurrent deep venous thrombosis are factors that cannot be changed. Deep venous thrombosis location and extent seem to predict severity of postthrombotic syndrome and are potentially suitable as patient selection criteria. Residual thrombosis and reflux are known to increase the incidence of postthrombotic syndrome, but are of limited use. More recently developed treatment options for deep venous thrombosis, such as new oral factor X inhibitors and catheter-directed thrombolysis, are available at the moment. Catheter-directed thrombolysis shows promising results in reducing the incidence of postthrombotic syndrome after deep venous thrombosis. The role of new oral factor X inhibitors in preventing postthrombotic syndrome is still to be determined.

Metabolic syndrome is an important cluster of coronary heart disease risk factors. However, it remains unclear to what extent metabolic syndrome is associated with demographic and potentially modifiable lifestyle factors among Korean persons with physical disabilities. This study aimed to determine the prevalence and influencing factors of metabolic syndrome among persons with physical disabilities using the Korean National Health Insurance Service-National Sample Cohort. The Adult Treatment Panel III criteria were used to define metabolic syndrome influencing factors and prevalence, which were evaluated in a representative sample from the 2013 Korean National Health Insurance Service-National Sample Cohort database. Characteristics were compared based on frequency using the χ 2 test. The associations between metabolic syndrome and its risk factors were estimated using logistic multivariable regression analysis. Metabolic syndrome was detected in 31.5% of the surveyed persons with physical disabilities. Female sex, age of ≥65 years, smoking, greater alcohol consumption, physical inactivity, higher body mass index, and a family history of diabetes were associated with increased risks of metabolic syndrome. The major risk factors for metabolic syndrome among persons with physical disabilities were obesity and older age. Performing physical activity was associated with a lower risk of metabolic syndrome. Therefore, we recommend using a continuous obesity management program and physical activity to prevent metabolic syndrome among persons with physical disabilities. Copyright © 2018.

Drug withdrawal symptoms in children after continuous infusions of fentanyl.

PubMed

French, J P; Nocera, M

1994-04-01

The purpose of this research was to determine the extent to which critically ill infants exhibited signs and symptoms of narcotic withdrawal after receiving continuous infusions of fentanyl. The convenience sample consisted of 12 pediatric intensive care unit (PICU) patients under 25 months of age who received fentanyl infusions for at least 24 hours. Drug withdrawal symptoms were monitored using the Neonatal Abstinence Score Tool (NAST), which assigns a score to each behavior indicative of withdrawal. A score of 8 or greater indicates Neonatal Abstinence Syndrome (NAS). Scoring began 4 hours after discontinuation of fentanyl and was conducted once per hour for 8 hours. Six subjects had a NAST score exceeding 8; these infants frequently exhibited tremors with or without stimulation, increased muscle tone, insomnia, and increased respiratory rate and effort. There were significant correlations between fentanyl dosage and NAST score (r = .76, p < 0.01), between length of infusion of fentanyl and NAST score (r = .70, p < 0.05), and between chloral hydrate dosage and NAST score (r = .62, p < 0.05). These findings suggest the need for an observation protocol and a possible weaning regimen after fentanyl is discontinued.

Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

Brain-derived neurotrophic factor (BDNF) is a type of growth factor that promotes growth and survival of neurons. Fetal exposure to opiates can lead to postnatal withdrawal syndrome, which is referred as neonatal abstinence syndrome (NAS). Preclinical and clinical studies have shown an association between opiates exposure and alteration in BDNF expression in the brain and serum levels in adult. However, to date, there are no data available on the effects of opiate exposure on BDNF levels in infant who are exposed to opiates in utero and whether BDNF level may correlate with the severity of NAS. To compare plasma BDNF levels among NAS and non-NAS infants and to determine the correlation of BDNF levels and the severity of NAS. This is a prospective cohort study with no intervention involved. Infants ≥35 weeks of gestation were enrolled. BDNF level was measured using enzyme-linked immunosorbent assay technique from blood samples drawn within 48 h of life. The severity of NAS was determined by the length of hospital stay, number of medications required to treat NAS. 67 infants were enrolled, 34 NAS and 33 non-NAS. Mean gestational age did not differ between the two groups. Mean birth weight of NAS infants was significantly lower than the non-NAS infants (3,070 ± 523 vs. 3,340 ± 459 g, p  = 0.028). Mean BDNF level in NAS group was 252.2 ± 91.6 ng/ml, significantly higher than 211.3 ± 66.3 ng/ml in the non-NAS group ( p  = 0.04). There were no differences in BDNF levels between NAS infants that required one medication vs. more than one medication (254 ± 91 vs. 218 ± 106 ng/ml, p  = 0.47). There was no correlation between the BDNF levels and length of hospital stay ( p  = 0.68) among NAS infants. Overall, there were no significant correlations between BDNF levels and NAS scores except at around 15 h after admission (correlation 0.35, p  = 0.045). Plasma BDNF level was significantly increased in NAS infants

Topiramate in opiate withdrawal.

Zullino, Daniele F; Cottier, Anne-Claude; Besson, Jacques

The alpha2-adrenergic agonist clonidine is the mainly used drug for the opiate withdrawal. Its efficacy and tolerance in treating withdrawal symptoms is, however, suboptimal. The pharmacological profile of topiramate suggests it could be rather valuable for opiate withdrawal, as there is some evidence that topiramate acts, among others, through inhibition of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors, which play an important role in the withdrawal-induced activation of the locus coeruleus (LC) by glutamate. Three patients undergoing an inpatient opiate detoxification program were treated with topiramate, which achieved a nearly complete control of withdrawal symptoms.

Cannabis use and dependence is a serious health and criminal justice issue among incarcerated populations internationally. Upon abrupt, enforced cessation of cannabis, prisoners may suffer irritability and anger that can lead to threatening behaviour, intimidation, violence, sleep disturbances and self-harm. Cannabis withdrawal syndrome, proposed for inclusion in the Diagnostic and Statistical Manual of Mental Disorders in 2013, has not been examined in Indigenous populations. Owing to the exceptionally high rates of cannabis use in the community, high proportions of Australian Indigenous prisoners may suffer from withdrawal upon entry to custody. 60 male and 60 female Indigenous prisoners (18-40 years) at a high risk of cannabis dependence will be recruited upon entry to custody. A pictorial representation of the standard Cannabis Withdrawal Scale will be tested for reliability and validity. Cortisol markers will be measured in saliva, as the indicators of onset and severity of cannabis withdrawal and psychological distress. The characteristics will be described as percentages and mean or median values with 95% CI. Receiver operator curve analysis will determine an ideal cut-off of the Cannabis Withdrawal Scale and generalised estimating equations modelling will test changes over time. The acceptability and efficacy of proposed resources will be assessed qualitatively using thematic analysis. A valid and reliable measure of cannabis withdrawal for use with Indigenous populations, the onset and time course of withdrawal symptoms in this population and the development of culturally acceptable resources and interventions to identify and manage cannabis withdrawal. The project has been approved by the James Cook University Human Research Ethics Committee (approval number H4651).The results will be reported via peer reviewed publications, conference, seminar presentations and on-line media for national and international dissemination.

Attenuated effects of experimenter-administered heroin in adolescent vs. adult male rats: physical withdrawal and locomotor sensitization

Objectives Early onset of heroin use during adolescence might increase chances of later drug addiction. Prior work from our laboratory suggests, however, that adolescent male rats are actually less sensitive than adults to some enduring effects of heroin self-administration. In the present study, we tested two likely correlates of sensitivity to behavioral reinforcement in rats: physical withdrawal and locomotor sensitization. Methods Adolescent (35 days old at start) and adult (79 days old) male Sprague-Dawley rats were administered escalating doses of heroin, increasing from 1.0 to 8.0 mg/kg (i.p.) every 12 hr, across 13 days. Somatic signs of spontaneous withdrawal were scored 12 and 24 hr after the last injection, then every 24 hr for 5 days; locomotion was recorded concurrently. Challenge injections of heroin (1 mg/kg i.p.) were given at 4 points: as the first of the escalating doses (day 1), at days 7 and 13 during the escalating regimen, and after 12 days of forced abstinence. Body mass and food intake were measured throughout experimentation. Results A heroin withdrawal syndrome was not observed among adolescents as it was among adults, including somatic signs as well as reduced locomotion, body mass, and food intake. On the other hand, heroin-induced locomotor sensitization did not differ across ages. Conclusion Reduced withdrawal is consistent with the attenuated reinforcing effects of heroin among adolescent male rats that we reported previously. Thus, it is possible that adolescent rats could reveal important neuroprotective factors for use in treatment of heroin dependence. PMID:22941050

Neuroleptic malignant syndrome (NMS) is a neurological emergency rarely encountered in clinical practice but with a high mortality rate. Cases associated with atypical antipsychotic use or termination of dopamine agonists have been seen in recent years. The purpose of this study was to assess the presence of risk factors for mortality by investigating all clinical and laboratory characteristics of cases with NMS. This descriptive, cross-sectional study retrospectively investigated all clinical and laboratory characteristics by scanning the ICD-10 codes of patients presenting to the XXXX Faculty of Medicine Emergency Department and diagnosed with NMS between 2006 and 2016. Patients were divided into surviving and non-surviving groups, and the data elicited were subjected to statistical comparisons. The mean age of the 18 patients diagnosed with NMS was 46.9 ± 4.8 years, and 50% were women. In addition to antipsychotics among the drugs leading to NMS, the syndrome also developed as a result of levodopa withdrawal in three patients and metoclopramide use in one patient. Statistically significant differences were determined between the surviving and non-surviving patients in terms of blood pressure, blood urea nitrogen (BUN), creatine kinase (CK) and mean platelet volume (MPV) values (p ≤ 0.05). In this study the most common agent that cause NMS was atypical antipsychotics. Also advanced age, increased blood pressure and serum CK, BUN and MPV values were identified as potential risk factors for mortality in NMS.

Rates of treatment seeking for cannabis are increasing, and relapse is common. Management of cannabis withdrawal is an important intervention point. No psychometrically sound measure for cannabis withdrawal exists, and as a result treatment developments cannot be optimally targeted. The aim is to develop and test the psychometrics of the Cannabis Withdrawal Scale and use it to explore predictors of cannabis withdrawal. A volunteer sample of 49 dependent cannabis users provided daily scores on the Cannabis Withdrawal Scale during a baseline week and 2 weeks of abstinence. Internal reliability (Cronbach's alpha=0.91), test-retest stability (average intra-class correlation=0.95) and content validity analysis show that the Cannabis Withdrawal Scale has excellent psychometric properties. Nightmares and/or strange dreams was the most valid item (Wald χ²=105.6, P<0.0001), but caused relatively little associated distress (Wald χ²=25.11, P=0.03). Angry outbursts were considered intense (Wald χ²=73.69, P<0.0001) and caused much associated distress (Wald χ²=45.54, P<0.0001). Trouble getting to sleep was also an intense withdrawal symptom (Wald χ²=42.31, P<0.0001) and caused significant associated distress (Wald χ²=47.76, P<0.0001). Scores on the Severity of Dependence Scale predicted cannabis withdrawal. The Cannabis Withdrawal Scale can be used as a diagnostic instrument in clinical and research settings where regular monitoring of withdrawal symptoms is required.

Anxiety is often a core element of withdrawal symptoms; however, risk factors associated with anxiety symptoms during the early stage of withdrawal in methamphetamine (METH) users are not well understood. Two hundred ten METH-dependent subjects who had been abstinent for 1 to 7 days were recruited. We used a set of self-administrative questionnaires eliciting information on sociodemographics, detailed drug use history and anxiety. Beck Anxiety Inventory (BAI) was used to measure anxiety symptoms. METH users had a mean BAI score of 6.9; 72 (34.3%) of the study sample had anxiety symptoms during acute METH withdrawal, including 42 (20.0%) with mild anxiety, 25 (11.9%) with moderate anxiety, and 5 (2.4%) with severe anxiety. In addition, gender (female), higher frequency of drug use, and history of polysubstance use were significantly correlated with anxiety symptoms during acute METH withdrawal. Anxiety symptoms appear to be common during the first week of METH abstinence, and several risk factors are identified.

Tobacco addiction is a chronic brain disorder that is characterized by a negative affective state upon smoking cessation and relapse after periods of abstinence. Previous research has shown that blockade of corticotropin-releasing factor (CRF) receptors with a nonspecific CRF1/CRF2 receptor antagonist prevents the deficit in brain reward function associated with nicotine withdrawal and stress-induced reinstatement of extinguished nicotine-seeking in rats. The aim of these studies was to investigate the role of CRF1 and CRF2 receptors in the deficit in brain reward function associated with precipitated nicotine withdrawal and stress-induced reinstatement of nicotine-seeking. The intracranial self-stimulation (ICSS) procedure was used to assess the negative affective state of nicotine withdrawal. Elevations in brain reward thresholds are indicative of a deficit in brain reward function. Stress-induced reinstatement of nicotine-seeking was investigated in animals in which responding for intravenously infused nicotine was extinguished by substituting saline for nicotine. In the ICSS experiments, the nicotinic receptor antagonist mecamylamine elevated the brain reward thresholds of the nicotine-dependent rats but not those of the control rats. The CRF1 receptor antagonist R278995/CRA0450 but not the CRF2 receptor antagonist astressin-2B prevented the elevations in brain reward thresholds associated with precipitated nicotine withdrawal. Furthermore, R278995/CRA0450 but not astressin-2B prevented stress-induced reinstatement of extinguished nicotine-seeking. Neither R278995/CRA0450 nor astressin-2B affected operant responding for chocolate-flavored food pellets. These studies indicate that CRF(1) receptors but not CRF(2) receptors play an important role in the anhedonic-state associated with acute nicotine withdrawal and stress-induced reinstatement of nicotine-seeking.

Relapse to opioids is often driven by the avoidance of the aversive states of opioid withdrawal. We recently demonstrated that activation of peroxisome proliferator-activated receptor gamma (PPARγ) by pioglitazone reduces the motivation for heroin and attenuates its rewarding properties. However, the role of PPARγ in withdrawal and other forms of relapse to heroin is unknown. To further address this issue, we investigated the role of PPARγ on the development and expression of morphine withdrawal in mice and the effect of pioglitazone on several forms of heroin relapse in rats. We induced physical dependence to morphine in mice by injecting morphine twice daily for 6 days. Withdrawal syndrome was precipitated on day 6 with an injection of naloxone. In addition, different groups of rats were trained to self-administer heroin and, after the extinction, the relapse was elicited by cues, priming, or stress. The effect of different doses of pioglitazone was tested on these different paradigms. Data show that chronic and acute administration of pioglitazone attenuates morphine withdrawal symptoms, and these effects are mediated by activation of PPARγ receptors. Activation of PPARγ by pioglitazone also abolishes yohimbine-induced reinstatement of heroin seeking and reduces heroin-induced reinstatement, while it does not affect cue-induced relapse. These findings provide new insights on the role of PPARγ on opioid dependence and suggest that pioglitazone may be useful for the treatment of opioid withdrawal in opioid-addicted individuals.

To explore the distribution characteristics of basic syndromes and its related factors in patients with chronic functional constipation (CFC). The complete data of 538 patients with CFC were collected and initial database was established with Epidata 3. 0. TCM syndrome typing was performed. The distribution characteristics of basic syndromes were analyzed using SPSS 17. 0 Software. The univariate and multivariate Logistic regression analyses were performed with SPSS 17. 0 Software to determine basic syndrome related factors such as age, engaged professionals, sleep quality, depression, mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation, and so on. The TCM syndrome frequency of CFC patients was sequenced from high to low as qi deficiency syndrome (380 cases, 70.6%), qi stagnation syndrome (337 cases, 62.6%), blood deficiency syndrome (234 cases, 43.5%), yin deficiency syndrome (220 cases, 40.9%), yang deficiency syndrome (197 cases, 36.6%), and others(58 cases, 10. 8%) . Most patients were complicated with complex syndromes, and the most common complex syndromes were qi deficiency complicated qi stagnation syndrome (275 cases, 51.1%) and qi deficiency complicated blood deficiency syndrome (222 cases, 41.3%). Aging, work fatigue, and exercise conditions were main related factors for qi deficiency syndrome (P <0. 01, P <0. 05). Poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, defecation barriers constipation were main related factors for qi stagnation syndrome (P <0.01). Sleep quality and poor emotional (depression and anxiety tendencies) were main related factors for blood deficiency syndrome (P <0. 01, P < 0.05). Stimulating beverages were main related factor for yin deficiency syndrome (P <0.05). Engaged in mental work and slow transit constipation were main related factors for yang deficiency syndrome (P < 0. 01, P <0. 05). CFC is featured

Effects of acute alcohol withdrawal on nest building in mice selectively bred for alcohol withdrawal severity

2017-01-01

Nest building has been used to assess thermoregulatory behavior and positive motivational states in mice. There are known genetic influences on ethanol withdrawal severity as well as individual/thermoregulatory nest building. Withdrawal Seizure-Prone (WSP-1, WSP-2) and Withdrawal Seizure-Resistant (WSR-1, WSR-2) mice were selectively bred for high vs low handling-induced convulsion (HIC) severity, respectively, during withdrawal from chronic ethanol vapor inhalation. They also differ in HIC severity during withdrawal from an acute, 4 g/kg ethanol injection. In our initial study, withdrawal from an acute dose of ethanol dose-dependently impaired nest building over the initial 24 h of withdrawal in genetically segregating Withdrawal Seizure Control (WSC) mice. In two further studies, acute ethanol withdrawal suppressed nest building for up to two days in WSP-1 females. Deficits in nest building from ethanol were limited to the initial 10 h of withdrawal in WSR-1 females and to the initial 24 h of withdrawal in WSP-1 and WSR-1 males. Effects of ethanol on nest building for up to two days were found in WSP-2 and WSR-2 mice of both sexes. Nest building deficits in female mice from the first replicate could not be explained by a general decrease in locomotor behavior. These results suggest that nest building is a novel behavioral phenotype for indexing the severity of acute ethanol withdrawal, and that genes contributing to this trait differ from those affecting acute withdrawal HIC severity.

This study compared the Glasgow Modified Alcohol Withdrawal Scale (GMAWS) and a newly devised 3-item "Anxiety Sweats Tremor" Scale (AST) to the Revised Clinical Institute Withdrawal Assessment Scale (CIWA-Ar)-the standard of care for symptom-triggered management of alcohol withdrawal syndrome. Our study took place over 2 separate 1-week observational periods, and included 332 serial evaluations from 85 unique patients. All study participants were treated per hospital protocol based on CIWA-Ar, with supplemental scoring initially by GMAWS and later by AST in tandem. Internal consistency, interitem correlation, and operational characteristics were explored. Median CIWA-Ar score across both phases was 6 (range 0-13), with a median GMAWS score of 2 (range 0-5) and an AST score of 3 (range 0-7). The internal consistency of CIWA-Ar and GMAWS were both poor, with Cronbach alpha scores of 0.46 (n = 156) and 0.41 (n = 156), respectively. The internal consistency of the AST scale was significantly better, with a Cronbach alpha of 0.68 (n = 176). AST identified individuals with CIWA-Ar ≥8 with an area under the receiver-operating characteristic curve of 0.83 (95% confidence interval 0.77-0.89), compared with 0.81 (95% confidence interval 0.74-0.88) for GMAWS. An AST score of ≥3 (out of a possible 9) predicted CIWA-Ar ≥8, with a sensitivity of 93% and a specificity of 63%, whereas the GMAWS had a sensitivity and specificity of 100% and 12%, respectively, based on previously defined cut-offs. A simple 3-item scale demonstrated good internal consistency and reliably identified individuals experiencing significant alcohol withdrawal. This scale needs to be tested in other settings and among patients with a broader spectrum of withdrawal severity.

Neurotensin is an autocrine trophic factor stimulated by androgen withdrawal in human prostate cancer.

PubMed Central

After therapeutic hormone deprivation, prostate cancer cells often develop androgen-insensitive growth through mechanisms thus far undefined. Neuropeptides have been previously implicated as growth factors in some prostate cancers. Here, we demonstrate that androgen-sensitive LNCaP human prostate cancer cells produce and secrete neurotensin following androgen withdrawal. We show that while LNCaP cells express the neurotensin receptor, only androgen-deprived cells exhibit a growth response to exogenous neurotensin. We further demonstrate that androgen-stimulated cells may be refractory to exogenous neurotensin due to androgen induction of a metalloprotease active toward neurotensin. Thus, prostate cancer cells deprived of androgen develop an alternative autocrine growth mechanism involving neurotensin. Images PMID:8197117

Growth factor withdrawal in combination with sodium butyrate addition extends culture longevity and enhances antibody production in CHO cells.

Hong, Jong Kwang; Lee, Gyun Min; Yoon, Sung Kwan

2011-09-10

The effect of growth factor (GF) and sodium butyrate (NaBu) on Chinese hamster ovary (CHO) cell growth, cell viability and antibody production was investigated using shaking flasks in GF-containing and GF-deficient medium containing 0, 1 and 3mM NaBu. The withdrawal of GF and the addition of NaBu suppressed cell growth, but they significantly increased specific antibody productivity, q(Ab). Interestingly, the withdrawal of GF in combination with the addition of NaBu markedly retarded cell death, leading to extended culture longevity. For instance, at 3mM NaBu, cell viability fell below 80% after day 4 in GF-containing medium, but it remained over 80% until day 18 in GF-deficient medium. Due to the enhanced q(Ab) and the extended culture longevity, approximately 2-fold increase in total antibody production was achieved in pseudo-perfusion culture with 1mM NaBu in GF-deficient medium, compared to the culture in GF-containing medium. The effect of GF and NaBu on the change in the expression and activity of cellular proteins, c-Myc, Bcl-2 and pyruvate dehydrogenase (PDH), was also investigated. Both the withdrawal of GF and the addition of NaBu decreased the expression of c-Myc. The expression of Bcl-2 was enhanced by the addition of NaBu in a dose-dependent manner while it was not affected by the withdrawal of GF. In addition, both the withdrawal of GF and the addition of NaBu reduced metabolic rates, q(Glc), q(Lac) and Y(Lac/Glc), and increased PDH activity while not affecting PDH expression, suggesting that they may reduce the glycolytic rates, but enhance the conversion rates of pyruvate to TCA intermediates. Taken together, the withdrawal of GF in combination with the addition of NaBu can be considered as a relevant strategy for alleviating NaBu-induced cell apoptosis and enhancing antibody production since it can be easily implemented as well as enhance q(Ab) and extend culture longevity.

To compare the psychometric properties of three cigarette withdrawal scales. An internet cohort study. Each of 4,644 current (44%), former (49%) and never smokers (7%) completed the three scales via the internet. A subsample completed the scales again after 14 days (n=1309), and indicated their smoking status after 42 days (n=1431). The Cigarette Withdrawal Scale (CWS), the Wisconsin Withdrawal Scale (WWS) and the Minnesota Withdrawal Form (MWF). All three scales covered the main elements in the Diagnostic and Statistical Manual version IV (DSM-IV) and the International Classification of Diseases version 10 (ICD-10) definitions of tobacco withdrawal, but WWS did not cover weight gain. Factor analyses indicated that only six factors were present in WWS, instead of the expected seven factors. Cronbach's alpha coefficients (0.76-0.93) were high for all scales. Test-retest coefficients were in the range of 0.66-0.86 for CWS and WWS, but were somewhat lower for some MWF items (range 0.52-0.80). In 324 ex-smokers who had quit smoking 31 days or less before baseline, craving predicted relapse at 14-day follow-up (CWS: odds ratio=1.53 per point, P=0.003; WWS: odds ratio=1.40, P=0.04; MWF: odds ratio=1.49, P=0.002). In 34 baseline smokers who had quit smoking by 14-day retest, an increase in craving (WWS and MWF), depressed mood (MWF) and difficulty concentrating (WWS) between baseline and retest predicted relapse at 42-day follow-up. In terms of construct validity, scales performed similarly, but performance on some key tests (e.g. withdrawal will increase post-cessation) were inadequate, due perhaps to methodological limitations. No scale showed a decisive advantage over the others. MWF has the advantage of brevity.

2005-03-01

Sleep apnea syndrome occurs when, during sleep, breathing stops for 10 seconds or longer, with an index of 5 times or more an hour. It is clinically characterized by loud snoring at night, continuous or interrupted by pauses followed by loud breathing. Sleep is fitful, broken by arousals, and yields little rest. There is daytime excessive sleepiness with repeated involuntary falling asleep, often unknown by the subject. In this article, we describe an observation of central sleep apnea syndrome in a female patient receiving an opiate replacement therapy. An analysis of the before and after methadone withdrawal polysomnograhic tracing was done for this patient. This diagnosis etiology and physiopathology are critically approached. Clinicians should be careful in treating induced sleep disorders in such patients. Prescribing benzodiazepines during an opiate withdrawal of the methadone type is not recommended when central apnea occurs.

Social withdrawal is described as the condition in which an individual experiences a desire to make social contact, but is unable to satisfy that desire. It is an important issue for patients with motor neurone disease who are likely to experience severe physical impairment. This study aims to reassess the psychometric and scaling properties of the MND Social Withdrawal Scale (MND-SWS) domains and examine the feasibility of a summary scale, by applying scale data to the Rasch model. The MND Social Withdrawal Scale was administered to 298 patients with a diagnosis of MND, alongside the Hospital Anxiety and Depression Scale. The factor structure of the MND Social Withdrawal Scale was assessed using confirmatory factor analysis. Model fit, category threshold analysis, differential item functioning (DIF), dimensionality and local dependency were evaluated. Factor analysis confirmed the suitability of the four-factor solution suggested by the original authors. Mokken scale analysis suggested the removal of item five. Rasch analysis removed a further three items; from the Community (one item) and Emotional (two items) withdrawal subscales. Following item reduction, each scale exhibited excellent fit to the Rasch model. A 14-item Summary scale was shown to fit the Rasch model after subtesting the items into three subtests corresponding to the Community, Family and Emotional subscales, indicating that items from these three subscales could be summed together to create a total measure for social withdrawal. Removal of four items from the Social Withdrawal Scale led to a four factor solution with a 14-item hierarchical Summary scale that were all unidimensional, free for DIF and well fitted to the Rasch model. The scale is reliable and allows clinicians and researchers to measure social withdrawal in MND along a unidimensional construct. © 2013. Published by Elsevier B.V. All rights reserved.

Drug addiction is an occurrence with physiological, psychological, and social outcomes. Repeated drug exposure causes neuronal adaptations and dependency. It has been shown that CaMKIIα enzyme contributes to morphine dependency. The locus coeruleus nucleus has been implied in the morphine withdrawal syndrome. This research focuses on the behavioral and molecular adaptations that occur in the locus coeruleus neurons in response to the chronic morphine exposure. Adult male Wistar rats were injected by morphine sulfate (10 mg/kg/s.c.) at an interval of 12 h for a period of nine subsequent days. On the tenth day, naloxone (1 mg/kg/i.p.) was injected 2 h after the morphine administration. Somatic withdrawal signs were investigated for 30 min. We concluded that the inhibition of CaMKIIα by administration of KN-93, the specific inhibitor of this enzyme, significantly attenuated some of the withdrawal signs. In molecular method, the expression of CaMKIIα protein has been enhanced in locus coeruleus of the morphine dependent rats. These findings indicate that CaMKIIα may be involved in the modulation of the naloxone-induced withdrawal syndrome, and treatment with KN-93 may have some effects on this system.

The aim of this study is to compare metabolic syndrome with syndrome Z growing epidemic in terms of risk factors, demographic variables, and gender differences in our large cohort at southeastern area in Turkey. Data of patients admitted to sleep clinic in University of Gaziantep from January 2006 to January 2011 were retrospectively evaluated. ATP III and JNC 7 were used for defining metabolic syndrome and hypertension. Data of 761 patients were evaluated. Hypertension, diabetes mellitus, coronary artery disease, pulmonary hypertension, and left ventricular hypertrophy were more common in patients with syndrome Z than in patients without metabolic syndrome. Age, waist/neck circumferences, BMI, triglyceride, glucose, and Epworth sleepiness scale score were detected higher, whereas the minimum oxygen saturation during sleep was lower in patients with syndrome Z. Metabolic syndrome was more common in sleep apneic subjects than in controls (58 versus 30 %). Female sleep apneics showed higher rate of metabolic syndrome than those of males (74 versus 52 %). Hypertension, diabetes mellitus, coronary artery disease, and left ventricular hypertrophy were detected higher in males with syndrome Z than in males without metabolic syndrome. Snoring and excessive daytime sleepiness were detected higher in females with syndrome Z than in females without metabolic syndrome. Systemic/pulmonary hypertension, diabetes mellitus, and left ventricular hypertrophy were more common in females with syndrome Z than in females without metabolic syndrome. Complaints of headache and systemic/pulmonary hypertension were more common among females than males with syndrome Z. Female syndrome Z patients had lower minimum oxygen saturation than male patients with syndrome Z. Metabolic syndrome in sleep apneic patients is more prevalent than in controls. All metabolic syndrome parameters were significantly different among obstructive sleep apneic patients with respect to gender with more severe

Several studies have demonstrated the vulnerability of the hippocampal formation (HF) to chronic alcohol consumption and withdrawal. Among the brain systems that appear to be particularly vulnerable to the effects of these conditions are the neuropeptide Y (NPY)-ergic and the cholinergic systems. Because these two systems seem to closely interact in the HF, we sought to study the effects of chronic alcohol consumption (6months) and subsequent withdrawal (2months) on the expression of NPY and on the cholinergic innervation of the rat dentate hilus. As such, we have estimated the areal density and the somatic volume of NPY-immunoreactive neurons, and the density of the cholinergic varicosities. In addition, because alcohol consumption and withdrawal are associated with impaired nerve growth factor (NGF) trophic support and the administration of exogenous NGF alters the effects of those conditions on various cholinergic markers, we have also estimated the same morphological parameters in withdrawn rats infused intracerebroventricularly with NGF. NPY expression increased after withdrawal and returned to control values after NGF treatment. Conversely, the somatic volume of these neurons did not differ among all groups. On other hand, the expression of vesicular acetylcholine transporter (VAChT) was reduced by 24% in ethanol-treated rats and by 46% in withdrawn rats. The administration of NGF to withdrawn rats increased the VAChT expression to values above control levels. These results show that the effects of prolonged alcohol intake and protracted withdrawal on the hilar NPY expression differ from those induced by shorter exposures to ethanol and by abrupt withdrawal. They also suggest that the normalizing effect of NGF on NPY expression might rely on the NGF-induced improvement of cholinergic neurotransmission in the dentate hilus. Copyright © 2016 Elsevier Inc.

The burnout syndrome is characterized by emotional exhaustion, depersonalization and reduced personal accomplishment in individuals professionally involved with others. The burnout syndrome is poorly recognized, particularly in France, as a distinct nosology from adaptation troubles, stress, depression, or anxiety. Several tools quantifying burnout and emotional exhaustion exist, the most spread is the questionnaire called Maslach Burnout Inventory. The burnout syndrome alters cardiovascular function and its neuroregulation by autonomic nervous system and is associated with: increased sympathetic tone to heart and vessels after mental stress, lowered physiological post-stress vagal rebound to heart, and lowered arterial baroreflex sensitivity. Job strain as burnout syndrome seems to be a real independent cardiovascular risk factor. Oppositely, training to manage emotions could increase vagal tone to heart and should be cardio-protective.

Withdrawal Phenomena: A Concept Analysis for the Development of a Nursing Diagnosis.

PubMed

Dändliker, This; Kolbe, Nina

This study explored the concept of withdrawal phenomena from the perspective of nurses, with the aim of developing a nursing diagnosis. Concept analysis was used as the framework of the study, a systematized review was conducted to identify relevant studies, and interpretation was based on qualitative content analysis. Specifying aspects, defining characteristics, related factors, and risk factors were extracted and classified into categories. Thirteen studies were identified as a basis for the construction of two nursing diagnoses: "withdrawal phenomena" and "risk of withdrawal complications." The proposed nursing diagnoses require further discussion. The NANDA International Diagnosis Development Committee was asked to examine the proposed diagnoses. However, it was too early to determine implications for nursing practice based on the results of this study.

A Single Brain-Derived Neurotrophic Factor Infusion into the Dorsomedial Prefrontal Cortex Attenuates Cocaine Self-Administration-Induced Phosphorylation of Synapsin in the Nucleus Accumbens during Early Withdrawal

Background: Dysregulation in the prefrontal cortex-nucleus accumbens pathway has been implicated in cocaine addiction. We have previously demonstrated that one intra-dorsomedial prefrontal cortex brain-derived neurotrophic factor (BDNF) infusion immediately following the last cocaine self-administration session caused a long-lasting inhibition of cocaine-seeking and normalized the cocaine-induced disturbance of glutamate transmission in the nucleus accumbens after extinction and a cocaine prime. However, the molecular mechanism mediating the brain-derived neurotrophic factor effect on cocaine-induced alterations in extracellular glutamate levels is unknown. Methods: In the present study, we determined the effects of brain-derived neurotrophic factor on cocaine-induced changes in the phosphorylation of synapsin (p-synapsin), a family of presynaptic proteins that mediate synaptic vesicle mobilization, in the nucleus accumbens during early withdrawal. Results: Two hours after cocaine self-administration, p-synapsin Ser9 and p-synapsin Ser62/67, but not p-synapsin Ser603, were increased in the nucleus accumbens. At 22 hours, only p-synapsin Ser9 was still elevated. Elevations at both time points were attenuated by an intra-dorsomedial prefrontal cortex brain-derived neurotrophic factor infusion immediately after the end of cocaine self-administration. Brain-derived neurotrophic factor also reduced cocaine self-administration withdrawal-induced phosphorylation of the protein phosphatase 2A C-subunit, suggesting that brain-derived neurotrophic factor disinhibits protein phosphatase 2A C-subunit, consistent with p-synapsin Ser9 dephosphorylation. Further, co-immunoprecipitation demonstrated that protein phosphatase 2A C-subunit and synapsin are associated in a protein-protein complex that was reduced after 2 hours of withdrawal from cocaine self-administration and reversed by brain-derived neurotrophic factor. Conclusions: Taken together, these findings demonstrate that

Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. To assess the effectiveness and safety of using a sedative compared to a non-opiate control for NAS due to withdrawal from opiates, and to determine which type of sedative is most effective and safe. This update included searches of the Cochrane Central Register of Controlled Trials (Issue 1, 2010), MEDLINE 1966 to April 2010 and abstracts of conference proceedings. Trials enrolling infants with NAS born to mothers with an opiate dependence with > 80% follow-up and using random or quasi-random allocation to sedative or control. Control could include another sedative or non-pharmacological treatment. Each author assessed study quality and extracted data independently. Seven studies enrolling 385 patients were included. There were substantial methodological concerns for most studies including the use of quasi-random allocation methods and sizeable, largely unexplained differences in reported numbers allocated to each group.One study reported phenobarbitone compared to supportive care alone did not reduce treatment failure or time to regain birthweight, but resulted in a significant reduction in duration of supportive care (MD -162.1 min/day, 95% CI -249.2, -75.1). Comparing phenobarbitone to diazepam, meta-analysis of two studies found phenobarbitone resulted in a significant reduction in treatment failure (typical RR 0.39, 95% CI 0.24, 0.62). Comparing phenobarbitone with chlorpromazine, one study reported no significant difference in treatment failure.In infants treated with an opiate, one study reported addition of clonidine resulted in no significant difference in treatment failure, seizures or mortality. In infants treated with an opiate, one study

Cannabis users display a constellation of withdrawal symptoms upon drug discontinuation, including sleep disturbances, irritability, and possibly memory deficits. In cannabinoid-dependent rodents, the CB(1) antagonist rimonabant precipitates somatic withdrawal and enhances forskolin-stimulated adenylyl cyclase activity in cerebellum, an effect opposite that of acutely administered ∆(9)-tetrahydrocannabinol (THC), the primary constituent in cannabis. Here, we tested whether THC-dependent mice undergoing rimonabant-precipitated withdrawal display short-term spatial memory deficits, as assessed in the Morris water maze. We also evaluated whether rimonabant would precipitate adenylyl cyclase superactivation in hippocampal and cerebellar tissue from THC-dependent mice. Rimonabant significantly impaired spatial memory of THC-dependent mice at lower doses than those necessary to precipitate somatic withdrawal behavior. In contrast, maze performance was near perfect in the cued task, suggesting sensorimotor function and motivational factors were unperturbed by the withdrawal state. Finally, rimonabant increased adenylyl cyclase activity in cerebellar, but not in hippocampal, membranes. The memory disruptive effects of THC undergo tolerance following repeated dosing, while the withdrawal state leads to a rebound deficit in memory. These results establish spatial memory impairment as a particularly sensitive component of cannabinoid withdrawal, an effect that may be mediated through compensatory changes in the cerebellum.

Abstract Introduction: Very early withdrawal from treatment in patients undergoing peritoneal dialysis (PD) is an increasingly important, but poorly understood, issue. Here, we identified the reasons and risk factors for very early withdrawal from PD. Methods: Incident PD patients from The First Affiliated Hospital of Sun Yat-sen University above 18 years who started treatment between January 1 2006 and December 31 2011 were included. Cessation of PD therapy within the first 90 days after beginning dialysis was classified as very early withdrawal. Results: Totally 1444 patients were enrolled. Of these, 71 (4.9%) withdrew from PD therapy during the first 90 days. Primary reasons for very early withdrawal included death (34 patients, 47.9%), transplantation (21 patients, 29.6%) and transfer to hemodialysis (14 patients, 19.7%). The leading reasons for death were cardiovascular and infectious disease, accounting for 41.2% (14 patients) and 23.5% (8 patients) of total deaths, respectively. Dialysate leakage (six patients, 42.9%) and catheter dysfunction (five patients, 35.7%) were the main reasons for transfer to hemodialysis. In multivariate analysis, predictors for very early PD withdrawal were older age (per decade increasing; hazard ratio [HR], 1.22; 95% confidence interval [CI], 1.03–1.45; p = .019), higher systolic blood pressure (per 10 mmHg increasing; HR, 1.35; 95% CI, 1.20–1.50; p < .001), lower hemoglobin (per 10 g/l increasing; HR, 0.67; 95% CI, 0.57–0.78; p < .001), lower high-density lipoprotein cholesterol (HR, 0.24; 95% CI, 0.10–0.54; p = .001) and lower residual urine volume (per 100 ml/d increasing; HR, 0.90; 95% CI, 0.84–0.95; p = .001). Conclusions: Death was the primary reason for very early withdrawal from PD. Risk factors for very early withdrawal from PD were older in age, had higher systolic blood pressure, lower hemoglobin, lower high-density lipoprotein cholesterol and lower residual urine volume

A Review of Alprazolam Use, Misuse, and Withdrawal

Alprazolam is one of the most widely prescribed benzodiazepines for the treatment of generalized anxiety disorder and panic disorder. Its clinical use has been a point of contention as most addiction specialists consider it to be highly addictive, given its unique psychodynamic properties which limit its clinical usefulness, whereas many primary care physicians continue to prescribe it for longer periods than recommended. Clinical research data has not fully shed light on its “abuse liability,” yet it is one of the most frequently prescribed benzodiazepines. “Abuse liability” is the degree to which a psychoactive drug has properties that facilitate people misusing it, or becoming addicted to it, and is commonly used in the literature. We have replaced it in our manuscript with “misuse liability” as it reflects a more updated terminology consistent with the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). In this paper, we have reviewed alprazolam’s indications for use, its effect on pregnant women, misuse liability, withdrawal syndrome, pharmacodynamic properties, and suggest better clinical prescription practice of alprazolam by presenting an indepth theory of its clinical effects with use and withdrawal.

The development of polycystic ovary syndrome and its exact pathophysiological mechanism is still unclear, but environmental and genetic factors likely play a role. Exposition to teratogenic effects during the prenatal development can lead to chronic diseases in the postnatal period. This finding confirms the common familial aggregation as well. A literature search was conducted up to January 1, 2016 for articles dealing with the genetic or epigenetic factors of polycystic ovary syndrome. This review will discuss the current understanding of the genetic basis and clinical presentation of this disease. Orv. Hetil., 2016, 157(32), 1275-1281.

Withdrawing to a virtual world: Associations between subtypes of withdrawal, media use, and maladjustment in emerging adults.

An approach-avoidance model of social withdrawal (Asendorpf, 1990) identifies 3 types of social withdrawal including shyness, unsociability, and avoidance. Each appears to be uniquely associated with varying indicators of maladjustment in emerging adulthood (Nelson, 2013) but little, if any, work has been done to see how they might be linked to media use in the third decade of life. Therefore, the purpose of this study was to examine longitudinally the links between subtypes of social withdrawal, connective media (e.g., e-mail, social networking) and problematic (forms of media such as violent video games that, when used in high amounts, have been found to be linked to indices of maladjustment) media use, and internalizing and externalizing behaviors. The participants in the study (Mage = 20.70, SD = 1.98, range = 18-29 at Time 2) consisted of 204 undergraduate students (58% female) recruited from 2 large public universities in the United States who completed questionnaires at 2 points of time separated by 1 year. Results revealed that avoidant individuals use problematic forms of media more than average, unsociable, and shy individuals. Furthermore, problematic media use predicted more withdrawn behavior at Time 2 and mediated the relation between avoidance and externalizing behaviors over time. Few problems were found for unsociable behavior. The need to differentiate between multiple forms of withdrawal in emerging adulthood and their links with problematic forms of media and subsequent risk factors is discussed.

Smokers are often advised to use nicotine lozenge when craving or withdrawal symptoms occur. This may be too late to prevent lapses. This study assessed if nicotine lozenge use prior to a common smoking trigger can minimize trigger induced increases in craving and withdrawal symptoms. Eighty-four smokers completed two laboratory sessions in random order. At one session, nicotine lozenge was given immediately after a stressor (to approximate current recommended use - i.e., after craving and withdrawal symptoms occur); at the other session subjects were randomized to receive nicotine lozenge at time points ranging from immediately to 30min prior to the stressor. Withdrawal symptoms and urge to smoke were measured using the Minnesota Nicotine Withdrawal Scale and the Questionnaire of Smoking Urges (QSU). Relative to receiving lozenge after the stressor, a smaller increase in pre-stressor to post-stressor withdrawal symptom scores occurred when lozenge was used immediately (p=0.03) and 10min prior (p=0.044) to the stressor. Results were similar for factors 1 and 2 of the QSU when lozenge was used immediately prior to the stressor (p<0.03) and for factor 1 of the QSU when lozenge was used 10min prior to the stressor (p=0.028). Absolute levels of post-stressor withdrawal symptom and urge to smoke severity were lower when lozenge was given prior to versus after a stressor. Administering the nicotine lozenge prior to a smoking trigger can decrease trigger induced craving and withdrawal symptoms. Future studies are needed to determine if such use would increase cessation rates. Clinicaltrials.gov # NCT01522963. Copyright © 2017 Elsevier Ltd. All rights reserved.

Δ9-Tetrahydrocannbinol (THC), the primary active constituent of Cannabis sativa, has long been known to reduce opioid withdrawal symptoms. Although THC produces most of its pharmacological actions through the activation of CB1 and CB2 cannabinoid receptors, the role these receptors play in reducing the variety of opioid withdrawal symptoms remains unknown. The endogenous cannabinoids, N-arachidonoylethanolamine (anandamide; AEA) and 2-arachidonylglycerol (2-AG), activate both cannabinoid receptors but are rapidly metabolized by fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), respectively. The objective of this study was to test whether increasing AEA or 2-AG, via inhibition of their respective hydrolytic enzymes, reduces naloxone-precipitated morphine withdrawal symptoms in in vivo and in vitro models of opioid dependence. Morphine-dependent mice challenged with naloxone reliably displayed a profound withdrawal syndrome, consisting of jumping, paw tremors, diarrhea, and weight loss. THC and the MAGL inhibitor 4-nitrophenyl 4-(dibenzo[d][1,3]dioxol-5-yl(hydroxy)methyl)piperidine-1-carboxylate (JZL184) dose dependently reduced the intensity of most measures through the activation of CB1 receptors. JZL184 also attenuated spontaneous withdrawal signs in morphine-dependent mice. The FAAH inhibitor N-(pyridin-3-yl)-4-(3-(5-(trifluoromethyl)pyridin-2-yloxy)benzyl)-piperdine-1-carboxamide (PF-3845) reduced the intensity of naloxone-precipitated jumps and paw flutters through the activation of CB1 receptors but did not ameliorate incidence of diarrhea or weight loss. In the final series of experiments, we investigated whether JZL184 or PF-3845 would attenuate naloxone-precipitated contractions in morphine-dependent ilea. Both enzyme inhibitors attenuated the intensity of naloxone-induced contractions, although this model does not account mechanistically for the autonomic withdrawal responses (i.e., diarrhea) observed in vivo. These results indicate

Rationale Tobacco withdrawal is a key factor in smoking relapse, but important questions about the withdrawal phenomenon remain. Objectives This research was intended to provide information about two core components of withdrawal (negative affect and craving): 1) how various withdrawal symptom profile dimensions (e.g., mean level, volatility, extreme values) differ between negative affect and craving; and 2) how these dimensions relate to cessation outcome. Methods Adult smokers (N=1504) in a double-blind randomized placebo-controlled smoking cessation trial provided real-time withdrawal symptom data four times per day for 4 weeks (2 weeks pre-quit and 2 weeks post-quit) via palmtop computers. Cessation outcome was biochemically confirmed 8-week point-prevalence abstinence. Results Examination of craving and negative affect dimensions following a cessation attempt revealed that craving symptoms differed from negative affect symptoms, with higher means, greater variability, and a greater incidence of extreme peaks. Regression analyses revealed that abstinence was associated with lower mean levels of both craving and negative affect and fewer incidences of extreme craving peaks. In a multivariate model, the increase in mean craving and negative affect scores each uniquely predicted relapse. Conclusions Real-time reports revealed different patterns of abstinence-related negative affect and craving and that dimensions of both predict cessation outcome, suggesting that negative affect and craving dimensions each has motivational significance. This underscores the complexity of withdrawal as a determinant of relapse and the need to measure its distinct components and dimensions. PMID:21416234

Refeeding syndrome is a life-threatening complication that may occur after initiation of nutritional therapy in malnourished patients, as well as after periods of fasting and hunger. Refeeding syndrome can be effectively prevented and treated if its risk factors and pathophysiology are known. The initial measurement of thiamine level and serum electrolytes, including phosphate and magnesium, their supplementation if necessary, and a slow increase in nutritional intake along with close monitoring of serum electrolytes play an important role. Since refeeding syndrome is not well known and the symptoms can be extremely heterogeneous, this complication is poorly recognized, especially against the background of severe disease and multimorbidity. This overview aims to summarize the current knowledge and increase awareness about refeeding syndrome.

Psychosocial Factors and Central Sensitivity Syndromes

Central sensitivity syndromes (CSSs) represent a heterogeneous group of disorders (e.g., fibromyalgia [FM], irritable bowel syndrome [IBS], chronic headache, temporomandibular disorders [TMDs], pelvic pain syndromes) that share common symptoms, with persistent pain being the most prominent feature. Although the etiology and pathophysiology of CSSs are currently incompletely understood, central sensitization has emerged as one of the significant mechanisms. Given that there are currently no known cures for CSSs, people living with these disorders must learn to cope with and manage their symptoms throughout their lives. Medical interventions alone have not proven to be sufficient for helping people with CSSs manage their symptoms. A biopsychosocial perspective that considers the ways that biological, psychological, and social factors work independently and jointly to affect a person's experience is the most effective conceptualization and guide for effective treatment. In this article, we discuss several psychological and social features that may influence the experience of a person with CSS and their symptom management, regardless of their specific diagnosis. We highlight the longitudinal aspect of adjustment to illness, the distinction between psychosocial factors as causes of symptoms versus modifiers and perpetuators of symptoms, dispel the notion that all patients with the same diagnosis are a homogeneous group (the “patient-uniformity myth”), and acknowledge the importance of environmental and situational context on symptom management for individuals with any CSS.

OBJECTIVE After prolonged opioid exposure, children develop opioid-induced hyperalgesia, tolerance, and withdrawal. Strategies for prevention and management should be based on the mechanisms of opioid tolerance and withdrawal. PATIENTS AND METHODS Relevant manuscripts published in the English language were searched in Medline by using search terms “opioid,” “opiate,” “sedation,” “analgesia,” “child,” “infant-newborn,” “tolerance,” “dependency,” “withdrawal,” “analgesic,” “receptor,” and “individual opioid drugs.” Clinical and preclinical studies were reviewed for data synthesis. RESULTS Mechanisms of opioid-induced hyperalgesia and tolerance suggest important drug- and patient-related risk factors that lead to tolerance and withdrawal. Opioid tolerance occurs earlier in the younger age groups, develops commonly during critical illness, and results more frequently from prolonged intravenous infusions of short-acting opioids. Treatment options include slowly tapering opioid doses, switching to longer-acting opioids, or specifically treating the symptoms of opioid withdrawal. Novel therapies may also include blocking the mechanisms of opioid tolerance, which would enhance the safety and effectiveness of opioid analgesia. CONCLUSIONS Opioid tolerance and withdrawal occur frequently in critically ill children. Novel insights into opioid receptor physiology and cellular biochemical changes will inform scientific approaches for the use of opioid analgesia and the prevention of opioid tolerance and withdrawal.

Generating an informative display of groundwater withdrawals can sometimes be difficult because the symbols for closely spaced wells can overlap. An alternative method for displaying groundwater withdrawals is to generate a “footprint” of the withdrawals. WellFootprint version 1.0 implements the Footprint algorithm with two optional variations that can speed up the footprint calculation. ModelMuse has been modified in order to generate the input for WellFootprint and to read and graphically display the output from WellFootprint.

Among patients with head and neck cancer comorbid alcohol use disorder is frequent which contributes to higher risk of developing perioperative alcohol withdrawal syndrome/delirium or delirium due to medical conditions. Although guidelines emphasize prevention and treatment of alcohol withdrawal in hospitalized patients, a validated systematic approach for management of these patients is still lacking. Our aim was to formatively evaluate our newly developed systematic approach in view of nurses' adherence to screening patients for regular alcohol consumption and managing their withdrawal symptoms using the Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised. We conducted a formative evaluation to improve the project's design and performance and used a retrospective chart review in a consecutive sample of all adult inpatients with head and neck cancer being assigned for surgery in a university hospital. Our bundle of interventions consisted of nurses' screenings for regular alcohol consumption, withdrawal risk assessment, offering patients a substitution therapy, nurses' assessments of withdrawal symptoms and symptom oriented withdrawal management. Proximate endpoints were analyzed descriptively at each component of the bundle in terms of frequencies and severity of withdrawal symptoms, frequencies of nurses' and doctors' screenings and nurses' assessments performed as required. Between 2013 and 2014, 87 inpatients met inclusion criteria and screenings by doctors/ nurses revealed 49 alcohol consumers, where six screenings were omitted by nurses and six by doctors. Twenty-one consumers were at risk and six of them developed an alcohol withdrawal syndrome. None of the 87 showed an alcohol withdrawal delirium, but five developed a delirium due to medical conditions. Nurses correctly conducted all preventive elements of the intervention bundle in 14 (58%) patients at risk but overall, only performed 50% of the required assessments. Although nurses safely

Retrospective analyses of data from the Platelet Receptor Inhibition in Ischemic Syndrome Management (PRISM), the National Registry of Myocardial Infarction 4, and the Global Registry of Acute Coronary Events (GRACE) trials revealed that the benefits of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) on acute coronary outcomes are rapidly lost and outcomes worsened if statins are discontinued during a patient's hospitalization for an acute coronary syndrome. Withdrawal of statin therapy in the first 24 hours of hospitalization for non-ST-elevation myocardial infarction increased the hospital morbidity and mortality rate versus continued therapy (11.9% vs 5.7%, p<0.01). Data from the Treating New Targets (TNT) study, however, suggested that short-term discontinuation of statin therapy in patients with stable cardiac conditions may not substantially increase the risk of acute coronary syndromes. In patients with acute coronary syndromes who discontinue statins, the rapid increase in risk of an event may result not only from the lost benefits from the therapy, but also from rebound inhibition of vascular protective substances and activation of vascular deleterious substances. Statins inhibit cholesterol synthesis in vascular cells. By reducing levels of isoprenoid intermediates, statins increase the production of nitric oxide and downregulate angiotensin II AT(1) receptors, endothelin-1, vascular inflammatory adhesion molecules, and inflammatory cytokines. These benefits are rapidly lost and often transiently reversed when statins are acutely discontinued. Acute removal of pleiotropic effects and rebound vascular dysfunction may be more important in an acute coronary event, where inflammation promotes rupture of atherosclerotic plaques and inflammatory and prothrombosis markers are present in high concentration, than in stable chronic vascular disease. In the absence of data from randomized controlled trials, current information suggests that

Most prostate cancers (PCs) become resistant to combined androgen blockade therapy with surgical or medical castration and antiandrogens after several years. Some of these refractory PCs regress after discontinuation of antiandrogen administration [antiandrogen withdrawal syndrome (AWS)]. Although the molecular mechanisms of the AWS are not fully understood because of the lack of suitable experimental models, one hypothesis of the mechanism is mutation of androgen receptor (AR). However, bicalutamide, which has become the most prevalent pure antiandrogen, does not work as an agonist for any mutant AR detected thus far in PC. To elucidate the mechanisms of the AWS, we established and characterized novel LNCaP cell sublines, LNCaP-cxDs, which were generated in vitro by culturing androgen-dependent LNCaP-FGC human PC cells in androgen-depleted medium with bicalutamide to mimic the combined androgen blockade therapy. LNCaP-FGC cells did not grow at first, but they started to grow after 6-13 weeks of culture. Bicalutamide stimulated LNCaP-cxD cell growth and increased prostate-specific antigen secretion from LNCaP-cxD cells both in vitro and in vivo. Sequencing of AR transcripts revealed that the AR in LNCaP-cxD cells harbors a novel mutation in codon 741, TGG (tryptophan) to TGT (cysteine; W741C), or in codon 741, TGG to TTG (leucine; W741L), in the ligand-binding domain. Transactivation assays showed that bicalutamide worked as an agonist for both W741C and W741L mutant ARs. Importantly, another antiandrogen, hydroxyflutamide, worked as an antagonist for these mutant ARs. In summary, we demonstrate for the first time that within only 6-13 weeks of in vitro exposure to bicalutamide, LNCaP-FGC cells, whose growth had initially been suppressed, came to use bicalutamide as an AR agonist via W741 AR mutation to survive. Our data strongly support the hypothesis that AR mutation is one possible mechanism of the AWS and suggest that flutamide might be effective as a second

Medical withdrawals from college for mental health reasons and their relation to academic performance.

A collaborative study among the university health service, the dean's office, and the registrar's office examined the academic performance of 77 students who took medical withdrawals for mental health reasons from Dartmouth College during a 3-year period. In 71.4% of the cases, students withdrew from a term in progress; the remainder arranged to withdraw after they had completed a term but before starting a new term. Depression was a major factor in approximately half of the withdrawals. Grade point average improved significantly after return from the withdrawal, with a large jump in individual term averages occurring between the terms immediately preceding and immediately following return. We found no significant difference between the number of students who experienced disciplinary trouble before withdrawal and those who were disciplined afterward. Students who were depressed at the time of withdrawal did not fare as well academically upon return as those students who had not been depressed. The data suggest that procedures for handling mental health withdrawals and readmission are important ways in which the campus counseling center can support the university's academic mission.

Patients with Cushing's syndrome and excess exogenous glucocorticoids have an increased risk for venous thromboembolism, as well as arterial thrombi. The patients are at high risk of thromboembolic events, especially during active disease and even in cases of remission and after surgery in Cushing's syndrome and withdrawal state in glucocorticoid users. We present a case of Cushing's syndrome caused by adrenocorticotropic hormone-secreting lung carcinoid tumor. Our patient developed acute mesenteric ischemia after video-assisted thoracoscopic surgery despite administration of sufficient glucocorticoid and thromboprophylaxis in the perioperative period. In addition, our patient developed hepatic infarction after surgical resection of the intestine. Then, the patient was supported by total parenteral nutrition. Our case report highlights the risk of microthrombi, which occurred in our patient after treatment of ectopic Cushing's syndrome. Guidelines on thromboprophylaxis and/or antiplatelet therapy for Cushing's syndrome are acutely needed. The present case showed acute mesenteric thromboembolism and hepatic infarction after treatment of ectopic Cushing's syndrome.Patients with Cushing's syndrome are at increased risk for thromboembolic events and increased morbidity and mortality.An increase in thromboembolic risk has been observed during active disease, even in cases of remission and postoperatively in Cushing's syndrome.Thromboprophylaxis and antiplatelet therapy should be considered in treatment of glucocorticoid excess or glucocorticoid withdrawal.

Despite the theoretical conceptualization of parental psychological control as a multidimensional construct, the majority of previous studies have examined psychological control as a unidimensional scale. Moreover, the conceptualization of shaming and its associations with love withdrawal and guilt induction are unclear. The current study aimed to fill these gaps by evaluating the latent factor structure underlying 18 items from Olsen et al. (2002) that were conceptually relevant to love withdrawal, guilt induction, and shaming practices in a sample of 169 mothers of Chinese-American preschoolers. A multidimensional three-factor model and bi-factor model were specified based on our formulated operational definitions for the three dimensions of psychological control. Both models were found to be superior to the unidimensional model. In addition, results from the bi-factor model and an additional second-order factor model indicated that psychological control is essentially empirically isomorphic with guilt induction. Although love withdrawal and shaming factors were also fairly strong indicators of psychological control, each exhibited important additional unique variability and mutual distinctiveness. Implications for the conceptualization of love withdrawal, guilt induction, and shaming as well as directions for future studies are discussed.

Hyperthyroidism with the syndrome of inappropriate secretion of TSH (SITSH) occurred by a decrease in hydrocortisone dose after surgery for Cushing's syndrome. This is a novel cause of SITSH. The aim of this study was to describe and discuss 2 cases of SITSH patients that were found after surgery for Cushing's syndrome. We also checked whether SITSH occurred in 7 consecutive patients with Cushing's syndrome after surgery. A 45-year-old Japanese woman with ACTH-independent Cushing's syndrome and a 37-year-old Japanese man with ACTH-dependent Cushing's syndrome presented SITSH caused by insufficient replacement of hydrocortisone for postoperative adrenal insufficiency. When the dose of hydrocortisone was reduced to less than 20 mg/d within 18 days after surgery, SITSH occurred in both cases. We examined whether the change of the hydrocortisone dose induced the secretion of TSH. Free T₃ and TSH were normalized by the hydrocortisone dose increase of 30 mg/d, and these were elevated by the dose decrease of 10 mg/d. We also checked TSH and thyroid hormone levels of the 7 consecutive patients with Cushing's syndrome after surgery. Six (66.6 %) of 9 patients showed SITSH. This is the first report that insufficient replacement of hydrocortisone after surgery for Cushing's syndrome caused SITSH. Hyperthyroidism by SITSH as well as adrenal insufficiency can contribute to withdrawal symptoms of hydrocortisone replacement. We need to consider the possibility of SITSH for the pathological evaluation of withdrawal syndrome of hydrocortisone replacement.

Neuroleptic malignant syndrome (NMS) is an uncommon but potentially serious idiosyncratic response to neuroleptic antipsychotics. It usually affects young males, but the risk has been seen to increase with certain factors including the administration practices of antipsychotic neuroleptics in these individuals. Even though no predictors for NMS are yet known, this article highlights the findings on certain risk factors as seen from a series of fifteen patients who developed NMS. Cautious use of neuroleptics in those at risk, early recognition and institution of immediate management is important.

2017-01-01

In their 2016 commentary on our theorizing about how youth withdrawal from economic and social participation in Japanese society (i.e., NEET and Hikikomori phenomena) stems from generational inequality of economic opportunities, Varnum and Kwon correctly point out that our explanation for withdrawal is yet untested. They then offered an alternative, evolutionary psychological explanation for withdrawal in which they claim that in resource-rich ecologies like Japan, the option to withdraw from participating in society is a possible life strategy, a strategy that would be much more costly in resource-poor ecologies. While we agree with this premise, we argue that this distal explanatory framework, at least in its current form, has limits in reconciling some of the more recent cross-cultural observations, as well as well-established sociological claims about the causes of withdrawal. Thus we argue that much work remains in refining and expanding the explanatory power of more distal explanations on the issue of withdrawal. Until then, the more proximal and culture-specific explanations are probably the useful and meaningful explanations for the withdrawal phenomenon.

Acute withdrawal, protracted abstinence and negative affect in alcoholism: Are they linked?

The role of withdrawal-related phenomena in development and maintenance of alcohol addiction remains under debate. A “self-medication” framework postulates that emotional changes are induced by a history of alcohol use, persist into abstinence, and are a major factor in maintaining alcoholism. This view initially focused on negative emotional states during early withdrawal: these are pronounced, occur in the vast majority of alcohol dependent patients, and are characterized by depressed mood and elevated anxiety. This concept lost popularity with the realization that, in most patients, these symptoms abate over 3 – 6 weeks of abstinence, while relapse risk persists long beyond this period. More recently, animal data have established that a prolonged history of alcohol dependence induces more subtle neuroadaptations. These confer altered emotional processing that persists long into protracted abstinence. The resulting behavioral phenotype is characterized by excessive voluntary alcohol intake and increased behavioral sensitivity to stress. Emerging human data support the clinical relevance of negative emotionality for protracted abstinence and relapse. These developments prompt a series of research questions: 1) Are processes observed during acute withdrawal, while transient in nature, mechanistically related to those that remain during protracted abstinence? 2) Is susceptibility to negative emotionality in acute withdrawal in part due to heritable factors, similar to what animal models have indicated for susceptibility to physical aspects of withdrawal? 3) To what extent is susceptibility to negative affect that persists into protracted abstinence heritable?

Stress has been shown to facilitate ethanol withdrawal-induced anxiety. Defining neurobiological mechanisms through which stress has such actions is important given the associated risk of relapse. While CRF has long been implicated in the action of stress, current results show that stress elevates the cytokine TNFα in the rat brain and thereby implicates cytokines in stress effects. In support of this view, prior TNFα microinjection into the central amygdala (CeA) of rats facilitated ethanol withdrawal-induced anxiety—a response that could not be attributed to an increase in plasma corticosterone. To test for a possible interaction between cytokines and CRF, a CRF1-receptor antagonist (SSR125543) administered prior to the repeated administration of TNFα or MCP-1/CCL2 reduced the magnitude of the withdrawal-induced anxiety. This finding provided evidence for cytokine action being dependent upon CRF. Additionally, the sensitizing effect of stress on withdrawal-induced anxiety was reduced by treating the repeated stress exposure prior to ethanol with the MEK inhibitor SL327. Consistent with cytokines having a neuromediator function distinct from a neuroimmune action, TNFα increased firing rate and GABA release from CeA neurons. Thus, an interaction of glial and neuronal function is proposed to contribute to the interaction of stress and chronic ethanol. Interrupting this potential glial-neuronal interaction could provide a novel means by which to alter the development of emotional states induced by stress that predict relapse in the alcoholic.

To explore the significance of the tumour necrosis factor-α/interleukin-10 ratio and the effect of continuous positive airway pressure in patients with different degrees of obstructive sleep apnoea hypopnoea syndrome severity. This study comprised 135 patients with obstructive sleep apnoea hypopnoea syndrome and 94 control subjects. Tumour necrosis factor-α and tumour necrosis factor-α/interleukin-10 ratio values were significantly higher in the obstructive sleep apnoea hypopnoea syndrome group than in the control group, but interleukin-10 was significantly lower. Tumour necrosis factor-α/interleukin-10 ratio values increased in line with the severity of obstructive sleep apnoea hypopnoea syndrome. In multivariate analysis, the tumour necrosis factor-α/interleukin-10 ratio correlated positively with the apnoea-hypopnoea index and all indices of obstructive sleep apnoea hypopnoea syndrome, except for age, body mass index and neck circumference. After one month of continuous positive airway pressure therapy, levels of tumour necrosis factor-α decreased; interleukin-10 showed no change. The results suggest that inflammation is activated and anti-inflammatory cytokines are decreased in obstructive sleep apnoea hypopnoea syndrome patients. Tumour necrosis factor-α/interleukin-10 ratio may prove useful for severity monitoring and management of obstructive sleep apnoea hypopnoea syndrome patients, and may reduce the need for polysomnography.

"Is That A Method of Birth Control?" A Qualitative Exploration of Young Women's Use of Withdrawal.

Despite its ubiquity, withdrawal is understudied as a family planning method. We investigated the context of and decision making around withdrawal use, drawing on in-depth, qualitative interviews with 38 Black and Latina women (ages 18 to 24). We examined contraceptive use histories to understand when and why participants used withdrawal. The majority of participants (n = 29; 76%) had used withdrawal in their lifetimes, though two-thirds of users mentioned withdrawal in their contraceptive histories only after interviewer prompts. Withdrawal was primarily used during transitions between contraceptive methods and when other methods were not desired. Relationship context was also an important factor, as many used withdrawal to increase intimacy with their partners; because they felt condoms were no longer necessary due to monogamy; or to fulfill their partners' preferences to increase sexual pleasure. Our findings indicate that decision making around withdrawal is embedded in situational and relational contexts. Future research should explore how health care providers and sex educators can engage young women in discussions of withdrawal's benefits and constraints. A harm reduction framework, which recognizes that optimal use of withdrawal is preferable to not using a pregnancy prevention method at all, may inform the ways that withdrawal can be addressed in clinical and educational settings.

To evaluate the rate of flare after etanercept (ETN) withdrawal in patients with juvenile idiopathic arthritis (JIA) who attained clinical remission while taking medication, and to identify predictors of flare. Patients were included with oligo- (oJIA) and rheumatoid factor-negative polyarticular JIA (pJIA) who received a first course of ETN for at least 18 months, maintained clinically inactive disease (CID) for at least 6 months during treatment, and were followed for 12 months after ETN withdrawal. Demographic and clinical features were collected at onset, at baseline (initiation of ETN), and at time of disease flare. After ETN withdrawal, 66 of the 110 patients enrolled (60%) flared with arthritis (of whom 7 flared with concurrent anterior uveitis; none with uveitis alone). The median time to flare was 4.3 months (interquartile range 2.5-6.4) with no evident differences between oJIA and pJIA. The number and type of joints involved at baseline and characteristics of ETN treatment/discontinuation were not associated with flare. Patients who flared were more frequently males (p = 0.034), positive for antinuclear antibody (ANA; p = 0.047), and had higher values of C-reactive protein (CRP; p = 0.012) at baseline. These variables remained significantly associated with flare in a multivariate logistic analysis, a model accounting for only 14% of the variability of the occurrence of the flare. Our results show that a significant proportion of patients with JIA who maintain CID for at least 6 months experience a relapse after ETN withdrawal. Male sex, presence of ANA, and elevated CRP at baseline were associated with higher risk of flare.

Ibogaine (IBO) is an alkaloid with putative antiaddictive properties, alleviating opiates dependence and withdrawal. The glutamate N-methyl-D-aspartate (NMDA) receptors have been implicated in the physiological basis of drug addiction; accordingly, IBO acts as a noncompetitive NMDA antagonist. The purpose of this study was to evaluate the effects of IBO on naloxone-induced withdrawal syndrome in morphine-dependent mice, focusing on the role of NMDA receptors. Jumping, a major behavioral expression of such withdrawal, was significantly (P<.01) inhibited by IBO (40 and 80 mg/kg, 64.2% and 96.9% inhibition, respectively) and MK-801 (0.15 and 0.30 mg/kg, 67.3% and 97.7%, respectively) given prior to naloxone. Coadministration of the lower doses of IBO (40 mg/kg) and MK-801 (0.15 mg/kg) results in 94.7% inhibition of jumping, comparable to the effects of higher doses of either IBO or MK-801. IBO and MK-801 also significantly inhibited NMDA-induced (99.0% and 71.0%, respectively) jumping when given 30 min (but not 24 h) prior to NMDA in nonaddictive mice. There were no significant differences in [3H]MK-801 binding to cortical membranes from naive animals, morphine-dependent animals, or morphine-dependent animals treated with IBO or MK-801. This study provides further evidence that IBO does have an inhibitory effect on opiate withdrawal symptoms and suggests that the complex process resulting in morphine withdrawal includes an IBO-sensitive functional and transitory alteration of NMDA receptor.

2011-03-01

The aim of the present study was to investigate the effects of a Rhodiola rosea L. extract on the prevention of the development of nicotine dependence and for the reduction of abstinence suffering following nicotine cessation in mice. Dependence was induced in mice by subcutaneous injections of nicotine (2 mg/kg, 4 times/day) for eight days. Spontaneous abstinence syndrome was evaluated 20 h after the last nicotine administration, by analysis of withdrawal signs, as affective (anxiety-like behaviour) and physical (somatic signs and locomotor activity). Rhodiola rosea L. extract was administered orally during nicotine treatment (10, 15 and 20 mg/kg) or during nicotine withdrawal (20 mg/kg). Results show that both affective and somatic signs (head shaking, paw tremors, body tremors, ptosis, jumping, piloerection and chewing) induced by nicotine withdrawal are abolished by administration of Rhodiola rosea L. extract in a dose-dependent fashion, during both nicotine exposure and nicotine cessation. In conclusion, our data encourage additional studies to define the use of R. rosea L. as a therapeutic approach in the treatment of smoking cessation.

Alcohol withdrawal syndrome (AWS) is a distressing condition, generally controlled by benzodiazepines (BZD's). Baclofen, a gamma-aminobutyric acid-B (GABAB) agonist, has also shown promising results in controlling AWS. As there are few studies comparing the efficacy and tolerability of chlordiazepoxide with baclofen, the present study was taken up. The objective of this study was to compare efficacy and tolerability of baclofen with chlordiazepoxide in uncomplicated AWS. Sixty subjects with uncomplicated AWS were randomized into two groups of 30 each, to receive baclofen (30 mg) or chlordiazepoxide (75 mg) in decremented fixed dose regime for 9 days. Clinical efficacy was assessed by Clinical Institute Withdrawal Assessment for Alcohol-Revised Scale (CIWA-Ar) and tolerability by the nature and severity of adverse events. Lorazepam was used as rescue medication. Secondary efficacy parameters were Clinical Global Impression scores, symptom-free days, and subject satisfaction as assessed by visual analog scale. This study was registered with Clinical Trial Registry-India (CTRI/2013/04/003588), also subsequently registered with WHO's ICTRP clinical trial portal. Both baclofen and chlordiazepoxide showed a consistent reduction in the total CIWA-Ar scores. However, chlordiazepoxide showed a faster and a more effective control of anxiety and agitation requiring lesser lorazepam supplementation, and also showed a better subject satisfaction compared to baclofen. Both the drugs showed good tolerability with mild self-limiting adverse events. The present study demonstrates that baclofen is not as good as chlordiazepoxide in the treatment of uncomplicated AWS. However, baclofen might be considered as an alternative. Copyright © 2016 Chang Gung University. Published by Elsevier B.V. All rights reserved.

Anhedonia, induced by nicotine withdrawal, may serve as an important affective sign that reinforces tobacco use and smoking relapse rates in humans. Animal models provide a way to investigate the underlying neurobiological factors involved in the decrease in responding for positive affective stimuli during nicotine withdrawal and may aid in drug development for nicotine dependence. Thus, we explored the use of the sucrose preference test to measure nicotine withdrawal-induced reduction in response for positive affective stimuli in mice. C57BL/6J and knockout (KO) mice were chronically exposed to different doses of nicotine through surgically implanted subcutaneous osmotic minipumps for 14days and underwent spontaneous nicotine withdrawal on day 15. A sucrose preference time course was performed and the results were compared to another well-established affective sign of nicotine withdrawal, the reduction in time spent in light side, using the Light Dark Box test. Subsequently, our results demonstrated a time-dependent and dose-related reduction in sucrose preference in nicotine withdrawn male C57BL/6J mice, indicative of a decrease in responding for positive affective stimuli. Furthermore, the sucrose preference reduction during nicotine withdrawal was consistent with decrease in time spent in the light side of the Light Dark Box test. We also found the reduction for positive affective stimuli and time spent in the light side was not present in nicotine withdrawn β2 and α6 KO mice, suggesting that these nicotinic subunits are involved in the affective signs of nicotine withdrawal. Thus, this report highlights the potential utility of the sucrose preference test as a useful measure of the decrease in responding for positive affective stimuli during spontaneous nicotine withdrawal.

To study the characteristics of traditional Chinese medicine (TCM) syndrome factors of patients from different areas of China with human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS). A cross-sectional investigation study was conducted in Henan, Guangdong and Yunnan Provinces and Xinjiang Uygur Autonomous Region of China from October 2008 to August 2010. Based on literature review and expert opinion, a clinical questionnaire of TCM syndromes was drawn up. This survey was carried out after the investigators were professionally trained. Wenfeng III Auxiliary Diagnosis and Treat System of TCM was used to analyze the frequencies of AIDS patients' signs and symptoms with scores above 70 of syndrome factors respectively. Based on this work, syndrome factors of AIDS were analyzed in different areas. There were 608 HIV/AIDS cases investigated from October 2008 to August 2010 in total; among them, 276 cases were from Henan, 126 cases from Guangdong, 120 cases from Xinjiang and 86 cases from Yunnan. The results of syndrome factor analysis indicated that the syndromes of four provinces were similar. HIV/AIDS patients in the four areas exhibited qi deficiency, blood deficiency, yin deficiency, yang deficiency, dampness, phlegm, qi stagnation and essence deficiency syndromes. Patients in each area also had their own characteristics, such as that the scores of dampness of Guangdong and yin deficiency of Xinjiang were higher than the other syndromes, whereas the scores of Henan Province were higher than the other areas. AIDS patients had higher scores of syndromes than HIV-infected patients. HIV/AIDS patients from different areas had similar syndrome elements. The theory of "AIDS toxin injuring primordial qi" can sum up the TCM etiology and pathogenesis of HIV/AIDS.

The rate of Neonatal Abstinence Syndrome (NAS) has drastically increased over the past decade. The average hospital expense per NAS patient has tripled, while the number of babies born to opioid-dependent mothers has increased to 5 in 1000 births. Current treatment options are limited to opioid replacement and tapering. Consequently, we examined the efficacy of prenatal, low-dose and short-term vigabatrin (γ-vinyl GABA, GVG) exposure for attenuating these symptoms as well as the metabolic changes observed in the brains of these animals upon reaching adolescence. Pregnant Sprague-Dawley rats were treated in one of four ways: 1) saline; 2) morphine alone; 3) morphine+GVG at 25 mg/kg; 4) morphine+GVG at 50 mg/kg. Morphine was administered throughout gestation, while GVG administration occurred only during the last 5 days of gestation. On post-natal day 1, naloxone-induced withdrawal behaviours were recorded in order to obtain a gross behaviour score. Approximately 28 days following birth, 18FDG microPET scans were obtained on these same animals (Groups 1, 2, and 4). Morphine-treated neonates demonstrated significantly higher withdrawal scores than saline controls. However, GVG at 50 but not 25 mg/kg/day significantly attenuated them. Upon reaching adolescence, morphine treated animals showed regionally specific changes in 18FDG uptake. Again, prenatal GVG exposure blocked them. These data demonstrate that low-dose, short-term prenatal GVG administration blocks naloxone-induced withdrawal in neonates. Taken together, these preliminary findings suggest that GVG may provide an alternative and long-lasting pharmacologic approach for the management of neonatal and adolescent symptoms associated with NAS.

Ethanol withdrawal syndrome is characterized by somatic and behavioral symptoms, including increased anxiety and anhedonia. In animal models, however, there are many studies on the anxiogenic effects occurring during the first 24h after ethanol withdrawal, while anhedonia has been overlooked. Recently, we have found that amphetamine withdrawal reduced novelty seeking and enhanced environmental habituation in mice, two motivation-related behaviors. We now investigate the effects of withdrawal from ethanol, a drug of abuse with a different pharmacological profile, on these two motivation-related behaviors. Swiss male mice (3months old) were treated with 1.8g/kg ethanol for 21 consecutive days in their home cages. Seven days after ethanol withdrawal, mice were tested in a free-choice novelty apparatus containing one familiar and one novel compartment. Novelty-seeking behavior was assessed by comparing time spent in the novel compartment versus the familiar compartment, whereas environmental habituation was concomitantly evaluated by the time-response curve of total locomotion (novel+familiar). Novelty seeking was decreased and environmental habituation was enhanced during ethanol withdrawal. These anhedonic responses were not associated with concurrent changes in the anxiety-like behavior of mice (as confirmed in the elevated plus-maze test). We propose that the concomitant evaluation of novelty-seeking behavior and environmental habituation can be useful to study the behavioral consequences not only of amphetamine withdrawal but also of ethanol withdrawal. Furthermore, the present data support recent clinical findings that suggest the occurrence of protracted anhedonia well beyond the limited period immediately following the abrupt cessation of ethanol intake.

The Japanese Orthopedic Association first proposed the concept of "locomotive syndrome" in 2007. It refers to circumstances in which elderly people need nursing care services or are at high risk of requiring such services within a short time. Recently, the public health burden of providing nursing care for elderly individuals has increased. Therefore, locomotive syndrome, and the means of preventing it, are a major public health focus in Japan. The purpose of this study was to investigate the relationships of lifestyle factors, such as smoking, alcohol consumption, sleep duration, and dental health, with locomotive syndrome. We conducted a cross-sectional study using an internet panel survey. The participants comprised 747 individuals aged 30-90 years. Factors related to demographics (age, sex), general health (number of teeth, presence of periodontal disease), and lifestyle (smoking, alcohol consumption, sleep duration) were assessed. We also used the 25-question Geriatric Locomotive Function Scale to determine whether each participant had locomotive syndrome. Multivariate analysis was conducted using logistic regression to investigate the independent relationships between locomotive syndrome and lifestyle factors after adjusting for sex and age. A greater proportion of women (17.7%) than men (11.2%) had locomotive syndrome (p < 0.05). Participants aged ≥65 years showed significantly higher percentages (men: 21.4%, women: 75.7%) of locomotive syndrome compared with those aged <65 years (p < 0.05). Logistic regression analysis revealed that older age (≥ 65 years), sex, current smoking status, number of existing teeth, and presence of periodontal disease were associated with locomotive syndrome, whereas sleep duration was not. The frequency of alcohol consumption, except for daily drinking, was also associated with locomotive syndrome. Our study indicates that lifestyle factors, such as smoking and number of existing teeth, may partly affect the

Our study objectives were as follows: assess exposure to psychosocial work demands among working pregnant women and women on preventive withdrawal from work; and measure the association between psychosocial work demands and major depressive symptoms, according to time of withdrawal from work. Karasek's abbreviated scale was used to measure psychosocial work demands (Job strain and "Iso-strain") and CES-D scale (Center for Epidemiological Studies Depression Scale) was used to measure major depressive symptoms (CES-D score≥23), at 24-26 weeks of pregnancy, among 3043 pregnant women in Montreal (Quebec) who worked at paid jobs at least 15 h/week and at least four consecutive weeks since the beginning of their pregnancy. Multivariate logistic regression models were built. At 24-26 weeks of pregnancy, 31.4% (956/3043) of pregnant women were on preventive withdrawal from work. They were more in "high-strain" (31.1% vs. 21.1%) and "Iso-strain" groups (21.0% vs. 14.2%) than those who continued to work (P<0.0001). The prevalence of major depressive symptoms was higher in women on preventive withdrawal from work (10.8%; CI 95%: 8.9 to 12.9) compared to working women (7.1%; CI 95%: 6.1-8.3). After adjustment for personal and professional risk factors, "Iso-strain" remained significantly associated with major depressive symptoms in working women (adjusted OR=1.75; CI 95%: [1.05 to 2.92]) and women on preventive withdrawal from work, regardless of duration of activity before withdrawal: 4 to 12 weeks (adjusted OR=2.72; CI 95%: [1.19-6.12]), 13 to 20 weeks (adjusted OR=3.51; CI 95%: [1.54-7.97]), and ≥21 weeks (adjusted OR=2.39; CI 95%: [1.10-5.20]). Psychosocial work demands are an important risk factor for the mental health of pregnant workers and require that preventive actions be put forward. Copyright © 2015 Elsevier Masson SAS.

Objectives To test the hypothesis that emotional withdrawal is an early indicator of affective disorder in infants heavily exposed prenatally to alcohol, which is independent of alcohol-related effects on mother-infant interaction and temperament and discriminated between children later diagnosed with fetal alcohol syndrome (FAS) and partial FAS (PFAS) and predicted cognitive and affective outcomes at 5 and 9 years. Methods The sample consisted of Cape Coloured (mixed ancestry) infants, whose mothers were interviewed during pregnancy regarding their alcohol consumption using a timeline follow-back approach. Infant emotional withdrawal (n = 85) was assessed on the Alarm Distress Baby Scale at 6.5 months. Mother-infant interaction was evaluated from video recordings during free play and infant feeding at 6.5 months (n = 127). Infant temperament was assessed by maternal report on the EAS Temperament Survey at 13 months (n = 119). Socio-demographic and psychological correlates of maternal alcohol use and infant iron deficiency were examined as potential confounders. The children were diagnosed for FAS/PFAS by expert dysmorphologists at 5 years; cognitive and affective function, at 5 and 9 years. Results Prenatal alcohol exposure was associated with increased infant emotional withdrawal and decreased activity, but unrelated to mother-infant interaction or any other temperament measures. Children later diagnosed with FAS and PFAS at 5 years exhibited more emotional withdrawal and less responsivity and activity as infants. Infant withdrawal, responsivity, quality of interaction, and maternal sensitivity also predicted poorer IQ and affective response at 5 and 9 years. When all four infant affective measures were examined simultaneously in a regression analysis, only infant emotional withdrawal persisted as a significant predictor of 9-year IQ. Conclusions This study is the first to document a direct effect of fetal alcohol exposure on emotional withdrawal in infancy

1. The effects of the calcium channel blocking agent, nitrendipine, were studied on seizures in mice produced during withdrawal from chronic benzodiazepine treatment and on the development of tolerance to benzodiazepines. 2. Nitrendipine produced a dose-dependent decrease in seizure incidence, when seizures were produced by the partial inverse agonist FG7142 during withdrawal from seven days treatment with flurazepam. 3. Nitrendipine did not raise the seizure thresholds in naïve mice to the full inverse agonist methyl-6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM), or to the gamma-aminobutyric acid (GABA) antagonist, bicuculline. 4. When given concurrently with flurazepam for seven days, nitrendipine did not affect the incidence of seizures during flurazepam withdrawal. 5. When given concurrently with the benzodiazepines, nitrendipine did not prevent the development of tolerance to midazolam general anaesthesia or tolerance to the ataxic actions of flurazepam or midazolam. 6. Chronic treatment with flurazepam for seven days did not affect the Kd or Bmax of [3H]-nimodipine binding in mouse whole brain or cerebral cortex. 7. These results with benzodiazepines are partially in contrast with those for ethanol, where nitrendipine not only decreased ethanol withdrawal seizures when given acutely, but also prevented the development of tolerance and withdrawal signs when given concurrently with ethanol. However, they do confirm the selectivity of nitrendipine for withdrawal-induced seizures. PMID:1963805

Total water withdrawals in Mississippi, 1990

Johnson, P.M.

1994-01-01

During 1990, the amount of water withdrawn from ground- and surface-water sources in Mississippi was about 3,600 Mgal/d (million gallons per day). Of this amount, 91 percent, or 3,300 Mgal/d, was withdrawn from freshwater sources. Of the total freshwater withdrawals, about 82 percent, or 2,700 Mgal/d, was withdrawn from ground-water sources. Total water withdrawals in Mississippi in 1990 for eight categories of use were as follows: irrigation, 1,900 Mgal/d; thermoelectric power, 700 Mgal/d; aquaculture, 400 Mgal/d; public supply, 320 Mgal/d; industrial and mining, 270 Mgal/d; domestic, 33 Mgal/d; commercial, 16 Mgal/d; and livestock, 16 Mgal/d. Overall, total withdrawals increased by 20 percent from 1985 to 1990, although the total population decreased about 2 percent. During the same period, total freshwater withdrawals increased by about 17 percent. Total saline with- drawals increased by about 60 percent from 1985 due to an increase in salin withdrawals for thermo- electric power generation. Total fresh and saline surface-water withdrawals decreased by about 6 percent from 1985, due to decrease in surface-water withdrawals for irrigation. Fresh ground-water withdrawals in Mississippi increased by about 33 percent, primarily due to an increase in irrigation. Since 1960, total ground- and surface-water with- drawals increased 70 percent for the same period. Irrigation had the greatest increase in with- drawals since 1960, with a 269 percent increase. Public supply had the second greatest, with a 178 percent increase.

Development of an alcohol withdrawal protocol: CNS collaborative exemplar.

Phillips, Susan; Haycock, Camille; Boyle, Deborah

2006-01-01

The purpose of this process improvement project was to develop an Alcohol Withdrawal Syndrome (AWS) management protocol for acute care. The prevalence of alcohol abuse in our society presents challenges for health professionals, and few nurses have received formal education on the identification and treatment of AWS, which has frequently resulted in ineffective, nonstandardized care. However, nurses practicing in medical-surgical, emergency, trauma, and critical care settings must be astute in the assessment and management of AWS. DESIGN/BACKGROUND/RATIONALE: Following an analysis of existing management protocols, a behavioral health clinical nurse specialist was asked to lead a work team composed of physicians, pharmacists, and nurses to develop a new evidence-based alcohol withdrawal protocol for acute care. By implementing a standardized assessment tool and treatment protocol, clinical nurse specialists empowered nursing staff with strategies to prevent the serious medical complications associated with AWS. FINDINGS/OUTCOMES: The development and integration of a safe and effective treatment protocol to manage AWS was facilitated by collaborative, evidence-based decision making. Clinical experience and specialty expertise were integrated by clinical nurse specialists skilled in group dynamics, problem-solving, and the implementation of change. Improving care of patients in AWS is an exemplar for clinical nurse specialist roles as change agent and patient advocate.

Baclofen shows potential for rapidly reducing symptoms of severe alcohol withdrawal syndrome (AWS) in people with alcoholism. Treatment with baclofen is easy to manage and rarely produces euphoria or other pleasant effects, or craving for the drug. This is an updated version of the original Cochrane Review published in 2015, Issue 4. To assess the efficacy and safety of baclofen for people with AWS. We updated our searches of the following databases to March 2017: the Cochrane Drugs and Alcohol Group Specialised Register, CENTRAL, PubMed, Embase, and CINAHL. We also searched registers of ongoing trials. We handsearched the references quoted in the identified trials, and sought information from researchers, pharmaceutical companies, and relevant trial authors about unpublished or uncompleted trials. We placed no restrictions on language. We included all randomised controlled clinical trials (RCTs) evaluating baclofen versus placebo or any other treatment for people with AWS. We excluded uncontrolled, non-randomised, or quasi-randomised trials. We included both parallel group and cross-over studies. We used standard methodological procedures expected by Cochrane. We included three RCTs with 141 randomised participants. We did not perform meta-analyses due to the different control interventions. For the comparison of baclofen and placebo (1 study, 31 participants), there was no significant difference in Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar) scores (very low quality evidence). For the comparison of baclofen and diazepam (1 study, 37 participants), there was no significant difference in CIWA-Ar scores (very low quality evidence), adverse events (risk difference (RD) 0.00, 95% confidence interval (CI) -0.10 to 0.10; very low quality evidence), dropouts (RD 0.00, 95% CI -0.10 to 0.10; very low quality evidence), and dropouts due to adverse events (RD 0.00, 95% CI -0.10 to 0.10; very low quality evidence).

We herein report the case of a 38-year-old Japanese woman with antithyroid arthritis syndrome who experienced severe migratory polyarthritis after the initiation of thiamazole therapy. The patient's symptoms promptly disappeared without any sequelae after the withdrawal of the drug. Antithyroid arthritis syndrome is poorly characterized, and the findings from our literature review indicate that this syndrome exhibits serological features that are distinct from those of antithyroid agent-induced vasculitis syndrome. The absence of autoantibodies, especially anti-neutrophil cytoplasmic antibodies, may help characterize and diagnose antithyroid arthritis syndrome. Furthermore, physicians' awareness of this syndrome is essential for its diagnosis in clinical practice. PMID:27980264

Activation of Peripheral κ-Opioid Receptors Normalizes Caffeine Effects Modified in Nicotine-Dependent Rats during Nicotine Withdrawal.

The study examined the effect of peripheral (intragastric) ICI-204,448, an agonist of gastric κ-opioid receptors, on the psychostimulating and anxiolytic effects of caffeine in nicotinedependent rats at the stage of nicotine withdrawal. In these rats, the effects of caffeine (10 mg/kg) were perverted. In nicotine-dependent rats, caffeine produced an anxiolytic effect accompanied by pronounced stimulation of motor activity, in contrast to anxiogenic effect induced by caffeine in intact rats without nicotine dependence. During nicotine withdrawal, nicotine-dependent rats demonstrated enhanced sensitivity to nicotine. Intragastric administration of κ-opioid receptor agonist ICI-204,448 normalized the effect of caffeine in nicotinedependent rats. We have previously demonstrated that activation of peripheral κ-opioid receptors inhibited central κ-opioid activity and eliminated manifestations of nicotine withdrawal syndrome in nicotine-dependent rats, e.g. metabolism activation, stimulation of motor activity, and enhancement of food consumption. In its turn, inhibition of central κ-opioid structures activates the brain adenosine system, which can attenuate the caffeine-induced effects in nicotine-dependent rats.

Mechanisms of metabolic syndrome (MetS) causation are complex, genetic and environmental factors are important factors for the pathogenesis of MetS In this study, we aimed to evaluate familial and genetic influences on metabolic syndrome risk factor and also assess association between FTO (rs1558902 and rs7202116) and CETP(rs1864163) genes' single nucleotide polymorphisms (SNP) with low HDL_C in the Tehran Lipid and Glucose Study (TLGS). The design was a cross-sectional study of 1776 members of 227 randomly-ascertained families. Selected families contained at least one affected metabolic syndrome and at least two members of the family had suffered a loss of HDL_C according to ATP III criteria. In this study, after confirming the familial aggregation with intra-trait correlation coefficients (ICC) of Metabolic syndrome (MetS) and the quantitative lipid traits, the genetic linkage analysis of HDL_C was performed using conditional logistic method with adjusted sex and age. The results of the aggregation analysis revealed a higher correlation between siblings than between parent-offspring pairs representing the role of genetic factors in MetS. In addition, the conditional logistic model with covariates showed that the linkage results between HDL_C and three marker, rs1558902, rs7202116 and rs1864163 were significant. In summary, a high risk of MetS was found in siblings confirming the genetic influences of metabolic syndrome risk factor. Moreover, the power to detect linkage increases in the one parameter conditional logistic model regarding the use of age and sex as covariates. Copyright © 2018. Published by Elsevier B.V.

Multiple risk factor syndrome is a clustering of cardiovascular risk factors, such as diabetes, dyslipidemia, hypertension, and obesity associated epidemiologically with insulin resistance. This report describes the clinical course of a patient suffering from severe periodontitis with multiple risk factor syndrome, and discusses the association between periodontal infection and systemic health. The patient had a history of type 2 diabetes, dyslipidemia, and hypertension for over 10 years. At baseline, her hemoglobin A1 c was 8.1%. However, she had no diabetic complications except periodontitis. The IgG antibody titers against Porphyromonas gingivalis FDC 381 and SU63 were elevated above the mean of healthy subjects +2 standard deviations. Intensive periodontal treatment, including periodontal surgery, was performed to reduce periodontal infection and bacteremia. Her systemic and periodontal conditions were evaluated longitudinally for 10 years. Following periodontal treatment, antibody titers against Porphyromonas gingivalis and hemoglobin A1c values were significantly improved. The other clinical data and medication for her systemic condition also remained stable during supportive periodontal therapy. However, she developed myocardial infarction, and showed continuous deterioration of hemoglobin A1 c level and periodontitis. The long-term clustering of risk factors, such as diabetes, dyslipidemia, hypertension, and periodontitis, are associated with the development of myocardial infarction. Treatment of systemic conditions in combination with comprehensive periodontal treatment is important in management of patients with multiple risk factor syndrome.

The definition of childhood metabolic syndrome has not been described clearly. Childhood obesity is increasing gradually, and the incidence of childhood metabolic syndrome is also rising. We aimed to show metabolic syndrome components and preventive factors for metabolic syndrome in obese children Methods: In the present study, 187 obese children and adolescents 5-18 years old were investigated retrospectively. Demographic data, anthropometric measurements, body mass index, blood pressure values, insulin levels, oral glucose tolerance test results, total cholesterol, high density lipoprotein, and triglyceride levels were obtained from hospital records. A body mass index > 95th percentile was considered obese. Insulin resistance was calculated according to the oral glucose tolerance test with 1.75 g/kg glucose maximum 75 g glucose. The insulin sensitivity index and homeostatic model assessment-insulin resistance (HOMA IR) were calculated and compared. Metabolic syndrome was diagnosed according to the modified WHO criteria adapted for metabolic syndrome in children. Abnormal glucose homeostasis was detected in 53% of subjects. Dyslipidaemia was present in 45.7% and hypertension in 16.6% of the patients. Metabolic syndrome was identified in 24.6% of obese children and adolescents. High HOMA-IR values and fasting glucose levels, elevated triglycerides and lower HDL levels were an indication of metabolic syndrome. Obesity and insulin resistance are significant factors for the development of metabolic syndrome in children and adolescents. In obese children higher HDL levels are preventive factor for metabolic syndrome. Preventing obesity and insulin resistance may decrease the prevalence of metabolic syndrome.

Indias García, Sílvia; De Paúl Ochotorena, Joaquín

2016-11-01

To adapt into Spanish three scales measuring frequency (SWFS) and motivation for social withdrawal (CSPS and SWMS) and to develop a scale capable of assessing the five motivations for social withdrawal. Participants were 1,112 Spanish adolescents, aged 12-17 years. The sample was randomly split into two groups in which exploratory and confirmatory (CFA) factor analyses were performed separately. A sample of adolescents in residential care (n = 128) was also used to perform discriminant validity analyses. SWFS was reduced to eight items that account for 40% of explained variance (PVE), and its reliability is high. SWMS worked adequately in the original version, according to CFA. Some items from the CSPS were removed from the final Spanish version. The newly developed scale (SWMS-5D) is composed of 20 items including five subscales: Peer Isolation, Unsociability, Shyness, Low Mood and Avoidance. Analyses reveal adequate convergent and discriminant validities. The resulting SWFS-8 and SWMS-5D could be considered useful instruments to assess frequency and motivation for social withdrawal in Spanish samples.

Temperament Factor Structure in Fragile X Syndrome: The Children's Behavior Questionnaire

Early patterns of temperament lay the foundation for a variety of developmental constructs such as self-regulation, psychopathology, and resilience. Children with fragile X syndrome (FXS) display unique patterns of temperament compared to age-matched clinical and non-clinical samples, and early patterns of temperament have been associated with later anxiety in this population. Despite these unique patterns in FXS and recent reports of atypical factor structure of temperament questionnaires in Williams Syndrome (Leyfer, John, Woodruff-Borden, & Mervis, 2012), no studies have examined the latent factor structure of temperament scales in FXS to ensure measurement validity in this sample. The present study used confirmatory factor analysis to examine the factor structure of a well-validated parent-reported temperament questionnaire, the Children's Behavior Questionnaire (Rothbart, Ahadi, Hershey, & Fisher, 2001), in a sample of 90 males with FXS ages 3-9 years. Our data produced a similar, but not identical, three-factor model that retained the original CBQ factors of negative affectivity, effortful control, and extraversion/surgency. In particular, our FXS sample demonstrated stronger factor loadings for fear and shyness than previously reported loadings in non-clinical samples, consistent with reports of poor social approach and elevated anxiety in this population. Although the original factor structure of the Children's Behavior Questionnaire is largely retained in children with FXS, differences in factor loading magnitudes may reflect phenotypic characteristics of the syndrome. These findings may inform future developmental and translational research efforts. PMID:24380785

Effects of CB1 and CRF1 receptor antagonists on binge-like eating in rats with limited access to a sweet fat diet: Lack of withdrawal-like responses

Positive reinforcement (e.g., appetitive, rewarding properties) has often been hypothesized to maintain excessive intake of palatable foods. Recently, rats receiving intermittent access to high sucrose diets showed binge-like intake with withdrawal-like signs upon cessation of access, suggesting negative reinforcement mechanisms contribute as well. Whether intermittent access to high fat diets also produces withdrawal-like syndromes is controversial. The present study therefore tested the hypothesis that binge-like eating and withdrawal-like anxiety would arise in a novel model of binge eating based on daily 10-min access to a sweet fat diet (35% fat kcal, 31% sucrose kcal). Within 2–3 weeks, female Wistar rats developed binge-like intake comparable to levels seen previously for high sucrose diets (~40% of daily caloric intake within 10 min) plus excess weight gain and adiposity, but absent increased anxiety-like behavior during elevated plus-maze or defensive withdrawal tests after diet withdrawal. Binge-like intake was unaffected by pretreatment with the corticotropin-releasing factor type 1 (CRF1) receptor antagonist R121919, and corticosterone responses to restraint stress did not differ between sweet-fat binge rats and chow-fed controls. In contrast, pretreatment with the cannabinoid type 1 (CB1) receptor antagonist SR147778 dose-dependently reduced binge-like intake, albeit less effectively than in ad lib chow or sweet fat controls. A priming dose of the sweet fat diet did not precipitate increased anxiety-like behavior, but rather increased plus-maze locomotor activity. The results suggest that CB1-dependent positive reinforcement rather than CRF1-dependent negative reinforcement mechanisms predominantly maintain excessive intake in this limited access model of sweet-fat diet binges.

Success Factors of European Syndromic Surveillance Systems: A Worked Example of Applying Qualitative Comparative Analysis.

Ziemann, Alexandra; Fouillet, Anne; Brand, Helmut; Krafft, Thomas

2016-01-01

Syndromic surveillance aims at augmenting traditional public health surveillance with timely information. To gain a head start, it mainly analyses existing data such as from web searches or patient records. Despite the setup of many syndromic surveillance systems, there is still much doubt about the benefit of the approach. There are diverse interactions between performance indicators such as timeliness and various system characteristics. This makes the performance assessment of syndromic surveillance systems a complex endeavour. We assessed if the comparison of several syndromic surveillance systems through Qualitative Comparative Analysis helps to evaluate performance and identify key success factors. We compiled case-based, mixed data on performance and characteristics of 19 syndromic surveillance systems in Europe from scientific and grey literature and from site visits. We identified success factors by applying crisp-set Qualitative Comparative Analysis. We focused on two main areas of syndromic surveillance application: seasonal influenza surveillance and situational awareness during different types of potentially health threatening events. We found that syndromic surveillance systems might detect the onset or peak of seasonal influenza earlier if they analyse non-clinical data sources. Timely situational awareness during different types of events is supported by an automated syndromic surveillance system capable of analysing multiple syndromes. To our surprise, the analysis of multiple data sources was no key success factor for situational awareness. We suggest to consider these key success factors when designing or further developing syndromic surveillance systems. Qualitative Comparative Analysis helped interpreting complex, mixed data on small-N cases and resulted in concrete and practically relevant findings.

Nicotinic Mechanisms Modulate Ethanol Withdrawal and Modify Time Course and Symptoms Severity of Simultaneous Withdrawal from Alcohol and Nicotine.

PubMed

Perez, Erika; Quijano-Cardé, Natalia; De Biasi, Mariella

2015-09-01

Alcohol and nicotine are among the top causes of preventable death in the United States. Unfortunately, people who are dependent on alcohol are more likely to smoke than individuals in the general population. Similarly, smokers are more likely to abuse alcohol. Alcohol and nicotine codependence affects health in many ways and leads to poorer treatment outcomes in subjects who want to quit. This study examined the interaction of alcohol and nicotine during withdrawal and compared abstinence symptoms during withdrawal from one of the two drugs only vs both. Our results indicate that simultaneous withdrawal from alcohol and nicotine produces physical symptoms that are more severe and last longer than those experienced during withdrawal from one of the two drugs alone. In animals experiencing withdrawal after chronic ethanol treatment, acute nicotine exposure was sufficient to prevent abstinence symptoms. Similarly, symptoms were prevented when alcohol was injected acutely in mice undergoing nicotine withdrawal. These experiments provide evidence for the involvement of the nicotinic cholinergic system in alcohol withdrawal. Furthermore, the outcomes of intracranial microinfusions of mecamylamine, a nonselective nicotinic receptor antagonist, highlight a major role for the nicotinic receptors expressed in medial habenula and interpeduncular nucleus during withdrawal. Overall, the data support the notion that modulating the nicotinic cholinergic system might help to maintain long-term abstinence from alcohol.

Effect of psychosocial factors on metabolic syndrome in male and female blue-collar workers.

Hwang, Won Ju; Lee, Chung Yul

2014-01-01

The purposes of this study were to examine the relationship between psychosocial factors and metabolic syndrome among male and female blue-collar workers, and which factors influence their metabolic syndrome by sex. A cross-sectional study was completed of 154 men and 80 women working at small companies in Korea. The data were collected through a structured questionnaire, blood test, and anthropometric and blood pressure measure. Metabolic syndrome was diagnosed from the results of blood test and the measurements of waist circumference and blood pressure. The prevalence of metabolic syndrome among male and female blue-collar workers was 24.0% and 7.5%, respectively. Multiple logistic regression analysis was performed to examine factors of metabolic syndrome associated with sex. After controlling for age, marital status, smoking, alcohol drinking, shift work, overtime work, and physical exercise, job stress (odds ratio [OR] = 3.10, P = 0.005) and risk perception (OR = 1.12, P = 0.016) were influencing factors for men, and low job stress (OR = 0.05, P = 0.04), low social support (OR = 1.51, P = 0.009), and risk perception (OR = 1.27, P = 0.023) for women. Metabolic syndrome among blue-collar workers is closely related to psychosocial factors, such as job stress, social support, and risk perception, with the effect of job stress a point of difference between men and women. Occupational health nurses should be cognizant of the importance of assessing the effect of psychosocial factors on cardiovascular risk for blue-collar workers. © 2012 The Authors.

Effects of early-life exposure to THIP on brainstem neuronal excitability in the Mecp2-null mouse model of Rett syndrome before and after drug withdrawal.

PubMed

2017-01-01

Rett syndrome (RTT) is mostly caused by mutations of the X-linked MECP2 gene. Although the causal neuronal mechanisms are still unclear, accumulating experimental evidence obtained from Mecp2 -/Y mice suggests that imbalanced excitation/inhibition in central neurons plays a major role. Several approaches may help to rebalance the excitation/inhibition, including agonists of GABA A receptors (GABA A R). Indeed, our previous studies have shown that early-life exposure of Mecp2-null mice to the extrasynaptic GABA A R agonist THIP alleviates several RTT-like symptoms including breathing disorders, motor dysfunction, social behaviors, and lifespan. However, how the chronic THIP affects the Mecp2 -/Y mice at the cellular level remains elusive. Here, we show that the THIP exposure in early lives markedly alleviated hyperexcitability of two types of brainstem neurons in Mecp2 -/Y mice. In neurons of the locus coeruleus (LC), known to be involved in breathing regulation, the hyperexcitability showed clear age-dependence, which was associated with age-dependent deterioration of the RTT-like breathing irregularities. Both the neuronal hyperexcitability and the breathing disorders were relieved with early THIP treatment. In neurons of the mesencephalic trigeminal nucleus (Me5), both the neuronal hyperexcitability and the changes in intrinsic membrane properties were alleviated with the THIP treatment in Mecp2-null mice. The effects of THIP on both LC and Me5 neuronal excitability remained 1 week after withdrawal. Persistent alleviation of breathing abnormalities in Mecp2 -/Y mice was also observed a week after THIP withdrawal. These results suggest that early-life exposure to THIP, a potential therapeutic medicine, appears capable of controlling neuronal hyperexcitability in Mecp2 -/Y mice, which occurs in the absence of THIP in the recording solution, lasts at least 1 week after withdrawal, and may contribute to the RTT-like symptom mitigation. © 2017 The Authors

Background Metabolic syndrome is a common nmetabolic ndisorder, which leads to early Cardio Vascular Disease and diabetes type II. The goal of this study was to determine the prevalence of metabolic syndrome and its risk factors in Kurdistan, Iran. Method: The data was extracted from provincial section of Iranian national non-communicable surveillance survey conducted in 2005. The study was a population-based survey with multi-stage cluster sampling method. Adult Treatment Panel-III measures were used for assessing the prevalence of metabolic syndrome among residents of Kurdistan Province aged 25 to 64 yr. EPI-Info 6 was used to enter the data and the data was analyzed using SPSS 11.5. Results: Totally, 1194 participants were recruited in our survey. The prevalence of metabolic syndrome was 29.1%. The prevalence was 41.3% among women and 17.1% among men (P= 0.001). As we go higher among age groups, the prevalence increases. Conclusion: This is the first study to investigate the metabolic syndrome in Kurdistan and Kurd ethnicity. The high level of metabolic syndromes prevalence especially among women shows the need and importance of suitable and effective preventive programs. These preventive programs must promote changes in lifestyle, especially with respect to nutrition, physical activities, and control of blood pressure. PMID:23113214

In this chapter, the authors review the history of the Waterloo Longitudinal Project (WLP), the first longitudinal study (1980–1992) dedicated to the study of social withdrawal, its correlates, and consequences. Theories underlying the WLP are described, as are its empirical findings. Recent research from other labs that has extended the findings of the original WLP is briefly described. The authors’ research that draws on the findings of WLP are noted as well. An underlying theme in this work is that relationships (and interactions) with parents and friends can serve as protective or exacerbating factors in the developmental course of social withdrawal and its concomitants (including social anxiety).

Obesity and metabolic syndrome is prevalent among Malaysian adolescents and has been associated with certain behavioural factors such as duration of sleep, screen time and physical activity. The aim of the study is to report the prevalence of overweight/obesity, metabolic syndrome and its risk factors among adolescents. A multi-staged cluster sampling method was used to select participants from urban and rural schools in Selangor, Perak and Wilayah Persekutuan Kuala Lumpur. Participants underwent anthropometric measurement and physical examination including blood pressure measurement. Blood samples were taken for fasting glucose and lipids and participants answered a self-administered questionnaire. Overweight and obesity was defined using the extrapolated adult body mass index (BMI) cut-offs of >25 kg/m2 and >30 kg/m2, according to the International Obesity Task Force (IOTF) criteria. Metabolic syndrome was defined based on International Diabetes Federation (IDF) 2007 criteria. Data were collected from 1361 participants. After excluding incomplete data and missing values for the variables, we analysed a sample of 1014 participants. Prevalence of overweight and obesity in this population was 25.4% (N = 258). The prevalence of metabolic syndrome was 2.6% in the population and 10% among the overweight and obese adolescents. Participants who slept between 7 and 9 hours a day has a lower risk of developing metabolic syndrome OR 0.38(0.15-0.94). Our results provide the prevalence of metabolic syndrome in Malaysian adolescents. Adequate sleep between 7 and 9 hours per day reduces the risk of developing metabolic syndrome.

Disruption of the CRF(2) receptor pathway decreases the somatic expression of opiate withdrawal.

PubMed

Papaleo, Francesco; Ghozland, Sandy; Ingallinesi, Manuela; Roberts, Amanda J; Koob, George F; Contarino, Angelo

2008-11-01

Escape from the extremely aversive opiate withdrawal symptoms powerfully motivates compulsive drug-seeking and drug-taking behaviors. The corticotropin-releasing factor (CRF) system is hypothesized to mediate the motivational properties of drug dependence. CRF signaling is transmitted by two receptor pathways, termed CRF(1) and CRF(2). To investigate the role for the CRF(2) receptor pathway in somatic opiate withdrawal, in the present study we used genetically engineered mice deficient in the CRF(2) receptor (CRF(2)-/-). We employed a novel, clinically relevant mouse model of 'spontaneous' opiate withdrawal as well as a classical opioid receptor antagonist (naloxone)-precipitated opiate withdrawal paradigm. To induce opiate dependence, mice were treated with intermittent escalating morphine doses (20-100 mg/kg, i.p.). We found that 8-128 h after the last opiate injection, CRF(2)-/- mice showed decreased levels of major somatic signs of spontaneous opiate withdrawal, such as paw tremor and wet dog shake, as compared to wild-type mice. Similarly, challenge with naloxone 2 h after the last morphine injection induced lower levels of paw tremor and wet dog shake in CRF(2)-/- mice as compared to wild-type mice. Despite the differences in somatic signs, wild-type and CRF(2)-/- mice displayed similar plasma corticosterone responses to opiate dosing and withdrawal, indicating a marginal role for the hypothalamus-pituitary-adrenal axis in the CRF(2) receptor mediation of opiate withdrawal. Our results unravel a novel role for the CRF(2) receptor pathway in opiate withdrawal. The CRF(2) receptor pathway might be a critical target of therapies aimed at alleviating opiate withdrawal symptoms and reducing relapse to drug intake.

Gamma-hydroxybutyrate (GHB) for treatment of alcohol withdrawal and prevention of relapses.

2010-02-17

Chronic excessive alcohol consumption may lead to dependence, and to alcohol withdrawal syndrome (AWS) in case of abrupt drinking cessation. Gamma-hydroxybutyric acid (GHB) can prevent and suppress withdrawal symptoms, and improve the medium-term abstinence rate. A clear balance between effectiveness and harmfulness has not been yet established. To evaluate the efficacy and safety of GHB for treatment of AWS and prevention of relapse We searched Cochrane Drugs and Alcohol Group' Register of Trials (October 2008), PubMed, EMBASE, CINAHL (January 2005 - October 2008), EconLIT (1969 to February 2008), reference list of retrieved articles Randomized controlled trials (RCTs) and Controlled Prospective Studies (CPS) evaluating the efficacy and the safety of GHB vs placebo or other pharmacological treatments. Three authors independently extracted data and assessed the methodological quality of studies. Thirteen RCTs were included. Eleven studies were conducted in Italy.For withdrawal syndrome, comparing GHB 50mg with placebo, results from 1 study, 23 participants favour GHB for withdrawal symptoms: WMD -12.1 (95% CI, -15.9 to -8.29) and side effects were more frequent in the placebo group: RR 16.2 (95% CI, 1.04 to 254.9).In the comparison with Chlormetiazole, for GHB 50mg, results from 1 study, 21 participants favour GHB for withdrawal symptoms: MD -3.40 (95% CI -5.09 to -1.71), for GHB 100mg, results from 1 study, 98 participants favour anticonvulsants for side effects: RR 1.84 (95% CI 1.19 to 2.85).At mid-term, comparing GHB with placebo, results favour GHB for abstinence rate (RR 5.35; 1.28-22.4), controlled drinking (RR 2.13; 1.07-5.54), relapses (RR 0.36; 0.21-0.63), and number of daily drinks (WMD -4.60; -6.18 to -3.02). GHB performed better than NTX and Disulfiram on abstinence (RR 2.59; 1.35-4.98, RR 1.66; 0.99-2.80 respectively). The association of GHB and NTX was better than NTX on abstinence (RR 12.2; 1.79-83.9), as well was the association of NTX, GHB and

The amount of public- and self-supplied water used for domestic, irrigation, livestock, aquaculture, industrial, mining, and thermoelectric power was estimated for state, county, and eastern and western regions of Washington during calendar year 2010. Withdrawals of freshwater for offstream uses were estimated to be about 4,885 million gallons per day. The total estimated freshwater withdrawals for 2010 was approximately 15 percent less than the 2005 estimate because of decreases in irrigation and thermoelectric power withdrawals.

The purposes of this study were to estimate the prevalence of metabolic syndrome and to investigate the risk factors associated with metabolic syndrome in Korean workers. This is a secondary data analysis study using the data set from the Korean National Health and Nutrition Examination Survey IV. A total of 1,545 workers over 20 yr of age were included in this analysis. The prevalence of metabolic syndrome was determined using the modified National Cholesterol Education Program Adult Treatment Panel III criteria. Waist circumference was based on the study of obesity guidelines. The overall prevalence of metabolic syndrome among Korean workers was 21.0% (28.5% men, 11.8% women). In a multiple logistic regression analysis, male workers with high job control and heavy alcohol consumption were significantly associated with metabolic syndrome. For women, low job control and current smoking increased the risk of metabolic syndrome. The risk of developing metabolic syndrome is strongly associated with level of job control in both male and female workers. These findings suggest that behavioral lifestyle modifications, including smoking cessation, moderating alcohol consumption, and controlling work-related factors and job control in the workplace should be considered for the prevention and management of metabolic syndrome in Korean workers.

Introduction Syndromic surveillance aims at augmenting traditional public health surveillance with timely information. To gain a head start, it mainly analyses existing data such as from web searches or patient records. Despite the setup of many syndromic surveillance systems, there is still much doubt about the benefit of the approach. There are diverse interactions between performance indicators such as timeliness and various system characteristics. This makes the performance assessment of syndromic surveillance systems a complex endeavour. We assessed if the comparison of several syndromic surveillance systems through Qualitative Comparative Analysis helps to evaluate performance and identify key success factors. Materials and Methods We compiled case-based, mixed data on performance and characteristics of 19 syndromic surveillance systems in Europe from scientific and grey literature and from site visits. We identified success factors by applying crisp-set Qualitative Comparative Analysis. We focused on two main areas of syndromic surveillance application: seasonal influenza surveillance and situational awareness during different types of potentially health threatening events. Results We found that syndromic surveillance systems might detect the onset or peak of seasonal influenza earlier if they analyse non-clinical data sources. Timely situational awareness during different types of events is supported by an automated syndromic surveillance system capable of analysing multiple syndromes. To our surprise, the analysis of multiple data sources was no key success factor for situational awareness. Conclusions We suggest to consider these key success factors when designing or further developing syndromic surveillance systems. Qualitative Comparative Analysis helped interpreting complex, mixed data on small-N cases and resulted in concrete and practically relevant findings. PMID:27182731

Strategies to improve I131 uptake in thyroid carcinoma include levothyroxine (LT4) withdrawal or thyrotropin (TSH) administration along with a low-iodine diet. We report five patients with papillary or follicular thyroid carcinoma who developed symptomatic hyponatremia during LT4 withdrawal and low-iodine diet. Four patients had pulmonary and/or brain metastases. All had restricted iodine intakes during LT4 withdrawal. Presenting complaints included weakness, dizziness, fainting spells, lethargy, and/or nausea. Baseline serum sodium levels while on LT4 suppression were normal. During presentation all were hypothyroid and serum sodium ranged from 110 to 121 mmol/L (normal 135-148). Despite hyponatremia, the plasma renin activity and serum aldosterone levels were suppressed, indicating volume expansion. The hyponatremia responded to fluid restriction and normalized after LT4 replacement. Low sodium intake, inappropriate antidiuretic hormone secretion syndrome (SIADH)-like disorder secondary to hypothyroidism and/or lung or cerebral metastases may have contributed to hyponatremia. The development of hyponatremia during LT4 withdrawal and low-iodine diet in otherwise healthy patients with thyroid carcinoma is extremely rare. However, elderly patients with metastatic thyroid carcinoma need observation during LT4 withdrawal combined with a low-iodine diet and should receive instruction to take iodine-free sodium chloride. Free water restriction may be necessary in some patients.

The body's total antioxidant capacity represents a sum of the antioxidant capacity of various tissues/organs. A decrease in the body's antioxidant capacity may induce oxidative stress and subsequent metabolic syndrome, a clustering of risk factors for type 2 diabetes and cardiovascular disease. The skin, the largest organ of the body, is one of the major components of the body's total antioxidant defense system, primarily through its xenobiotic/drug biotransformation system, reactive oxygen species-scavenging system, and sweat glands- and sebaceous glands-mediated excretion system. Notably, unlike other contributors, the skin contribution is variable, depending on lifestyles and ambient temperature or seasonal variations. Emerging evidence suggests that decreased skin's antioxidant and excretory functions (e.g., due to sedentary lifestyles and low ambient temperature) may increase the risk for metabolic syndrome. This review focuses on the relationship between the variability of skin-mediated detoxification and elimination of exogenous and endogenous toxic substances and the development of metabolic syndrome. The potential role of sebum secretion in lipid and cholesterol homeostasis and its impact on metabolic syndrome, and the association between skin disorders (acanthosis nigricans, acne, and burn) and metabolic syndrome are also discussed.

Nicotine withdrawal reduces neurobiological responses to nonsmoking rewards. Insight into these reward deficits could inform the development of targeted interventions. This study examined the effect of withdrawal on neural and behavioral responses during a reward prediction task. Smokers (N = 48) attended two laboratory sessions following overnight abstinence. Withdrawal was manipulated by having participants smoke three regular nicotine (0.6 mg yield; satiation) or very low nicotine (0.05 mg yield; withdrawal) cigarettes. Electrophysiological recordings of neural activity were obtained while participants completed a reward prediction task that involved viewing four combinations of predictive and reward-determining stimuli: (1) Unexpected Reward; (2) Predicted Reward; (3) Predicted Punishment; (4) Unexpected Punishment. The task evokes a medial frontal negativity that mimics the phasic pattern of dopaminergic firing in ventral tegmental regions associated with reward prediction errors. Nicotine withdrawal decreased the amplitude of the medial frontal negativity equally across all trial types (p < .001). Exploratory analyses indicated withdrawal increased time to initiate the next trial following unexpected punishment trials (p < .001) and response time on reward trials during withdrawal was positively related to nicotine dependence (p < .001). Nicotine withdrawal had equivocal impact across trial types, suggesting reward processing deficits are unlikely to stem from changes in phasic dopaminergic activity during prediction errors. Effects on tonic activity may be more pronounced. Pharmacological interventions directly targeting the dopamine system and behavioral interventions designed to increase reward motivation and responsiveness (eg, behavioral activation) may aid in mitigating withdrawal symptoms and potentially improving smoking cessation outcomes. Findings from this study indicate nicotine withdrawal impacts reward processing signals that are observable in

Metabolic syndrome (MetS), a concurrence of hypertension, abdominal obesity, impaired fasting glucose, and dyslipidemia, has been shown to be a risk factor for cardiovascular disease. Insulin resistance has been thought to be one of the pathophysiologies of the syndrome. Reduction of the underlying causes of MetS, such as obesity, physical inactivity, and atherogenic diet, is first-line therapy. Treatment of hypertension and other cardiometabolic risk factors of MetS is also required. This article reviews the treatment of the metabolic syndrome with a focus on the importance of lifestyle changes and treatment of hypertension.

Metabolic syndrome progresses to diabetes and determinants of this progression like hyperinsulinemia, hypertriglyceridemia and genetic factors have been speculative. The present study was aimed at quantifying the insulin resistance and influence of family history of diabetes in subjects with metabolic syndrome developing prediabetes and diabetes. Consecutive subjects attending the endocrine clinic were evaluated for metabolic syndrome as per definition of International Diabetes Federation, 2005. The family history of diabetes in their first degree relatives was ascertained and Homeostasis model assessment of Insulin resistance (HOMA-IR), Homeostasis model assessment for beta cell function (HOMA-B) and Quantitative insulin sensitivity check index (QUICKI) were calculated in 163 subjects enrolled. HOMA-IR was higher (p<0.05) but HOMA-B and QUICKI were lower (p<0.0001) in subjects with metabolic syndrome+prediabetes or diabetes compared to metabolic syndrome with normal glucose tolerance. HOMA-B was lower and prevalence of prediabetes and diabetes was higher in metabolic syndrome subjects with family history of diabetes than in those without such family history (p<0.05). subjects with metabolic syndrome having prediabetes and diabetes had more severe insulin resistance than those with metabolic syndrome only. Beta cell dysfunction was remarkable and prevalence of prediabetes was high in metabolic syndrome subjects with family history of diabetes. Both the severity of the insulin resistance and family history of diabetes are therefore proposed to be determinants of diminished Beta cell function leading to diabetes in metabolic syndrome.

Conditional Switching of Vascular Endothelial Growth Factor (VEGF) Expression in Tumors: Induction of Endothelial Cell Shedding and Regression of Hemangioblastoma-Like Vessels by VEGF Withdrawal

NASA Astrophysics Data System (ADS)

Benjamin, Laura E.; Keshet, Eli

1997-08-01

We have recently shown that VEGF functions as a survival factor for newly formed vessels during developmental neovascularization, but is not required for maintenance of mature vessels. Reasoning that expanding tumors contain a significant fraction of newly formed and remodeling vessels, we examined whether abrupt withdrawal of VEGF will result in regression of preformed tumor vessels. Using a tetracycline-regulated VEGF expression system in xenografted C6 glioma cells, we showed that shutting off VEGF production leads to detachment of endothelial cells from the walls of preformed vessels and their subsequent death by apoptosis. Vascular collapse then leads to hemorrhages and extensive tumor necrosis. These results suggest that enforced withdrawal of vascular survival factors can be applied to target preformed tumor vasculature in established tumors. The system was also used to examine phenotypes resulting from over-expression of VEGF. When expression of the transfected VEGF cDNA was continuously ``on,'' tumors became hyper-vascularized with abnormally large vessels, presumably arising from excessive fusions. Tumors were significantly less necrotic, suggesting that necrosis in these tumors is the result of insufficient angiogenesis.

Objectives Guatemala is experiencing a nutritional and lifestyle transition. While chronic malnutrition is prevalent, overweight, obesity and chronic diseases have increased substantially in the country. This study was conducted to investigate the prevalence of metabolic syndrome and the associated cardiovascular risk factors in the pre-adolescent Guatemalan population. Methods A cross-sectional study was conducted among 302 Guatemalan children (8–13 years old) attending public and private schools in the Municipality of Chimaltenango. Demographic data and anthropometric and blood pressure measurements were collected. A blood sample was taken after an 8-hour overnight fast and analyzed for glucose, triglyceride and high-density lipoprotein cholesterol levels. The data were analyzed to identify factors associated with metabolic syndrome and with its components. Results The prevalence of metabolic syndrome in the study population was 2.0%. However, approximately 54% of the children had at least one component of metabolic syndrome, while none had four or five of the components. The three most prevalent risk factors were high triglycerides (43.4%), low HDL cholesterol (17.2%) and obesity (12.3%). Boys were more likely to be obese than girls and rural children were more likely to have higher triglyceride levels than urban children. Conclusions Although the prevalence of metabolic syndrome is low, the fact that majority of the children already have at least one component of metabolic syndrome is cause for concern since components of metabolic syndrome can continue into adulthood and increase the risk for chronic diseases later in life. Therefore, immediate action should be taken to address the problem. PMID:24337775

To determine the prevalence of burnout syndrome among resident physicians of various specialties and to evaluate associated factors. The Maslach Burnout Inventory questionnaire and a sociodemographic questionnaire were used to evaluate factors associated with the syndrome. Burnout was defined as the association of high emotional exhaustion, depersonalization and low professional achievement. Multivariate analysis was performed after adjustment of the Poisson model with the identification of risk factors and calculation of prevalence ratios (PR). Of the 250 resident physicians registered with Hospital das Clínicas of Pernambuco, 129 participated in the study. In the three domains that characterize burnout syndrome, we found a low level of professional achievement in 94.6% of resident physicians interviewed, a high level of depersonalization in 31.8%, and 59.7% with a high level of emotional exhaustion. The prevalence of burnout was 27.9%. Having suffered a stressful event in the last six months (PR: 8.10; 95CI 1.2-57.2) and being a student of surgical specialty (PR: 1.99; 95CI 1.2-3.3) were independently associated with burnout. The prevalence of burnout found in resident physicians is in accordance with previous Brazilian studies. Residents of surgical specialties and those who suffered some stressful event were identified as susceptible in this study. The early identification of risk factors is fundamental for the implementation of preventive measures against burnout syndrome.

The burnout syndrome is beginning to be regarded as an occupational illness of high prevalence among nursing in Spain. Individuals suffering from the syndrome manifest important health problems. More information about prevalence and risk factors for burnout is needed to prevent the syndrome and to determine the most appropriate clinical interventions when the disorder appears. Burnout levels were evaluated in a group of nurses. The objectives of this study were to estimate the prevalence of burnout, to identify the variables related to burnout and to propose a risk profile for this syndrome among the nursing personnel. The study was carried out in public health centers in Andalusia (Spain). The sample consisted of 676 nursing professionals from public health centers. Dependent variables were the three Burnout dimensions: emotional exhaustion, depersonalization and personal accomplishment. Independent variables were socio-demographic, organizational, personality-related variables. The nurses manifested average to high burnout levels. There were statistically significant differences in burnout levels associated with the following variables: age, gender, marital status, having children, level of healthcare, type of work shift, healthcare service areas and conducting administrative tasks. Burnout was also associated with personality-related variables. The prevalence of burnout among nursing professionals is high. Gender, age, marital status, level of healthcare, work shift and healthcare service areas predicted at least one of the dimensions of the syndrome. Neuroticism, agreeability, extraversion and conscientiousness are personality traits that predict at least two of the dimensions of burnout syndrome in nurses. Therefore, personality factors should be considered in any theory of risk profiles for developing burnout syndrome in the nursing profession. Copyright © 2014 Elsevier Ltd. All rights reserved.

Smoking cessation results in withdrawal symptoms such as craving and negative mood that may contribute to lapse and relapse. Little is known regarding whether these symptoms are associated with the nicotine or non-nicotine components of cigarette smoke. Using arterial spin labeling, we measured resting-state cerebral blood flow (CBF) in 29 adult smokers across four conditions: (1) nicotine patch+denicotinized cigarette smoking, (2) nicotine patch+abstinence from smoking, (3) placebo patch+denicotinized cigarette smoking, and (4) placebo patch+abstinence from smoking. We found that changes in self-reported craving positively correlated with changes in CBF from the denicotinized cigarette smoking conditions to the abstinent conditions. These correlations were found in several regions throughout the brain. Self-reported craving also increased from the nicotine to the placebo conditions, but had a minimal relationship with changes in CBF. The results of this study suggest that the non-nicotine components of cigarette smoke significantly impact withdrawal symptoms and associated brain areas, independently of the effects of nicotine. As such, the effects of non-nicotine factors are important to consider in the design and development of smoking cessation interventions and tobacco regulation.

Dramatic decreases in brain reward function during nicotine withdrawal.

Tobacco smoking is a worldwide public health problem. In the United States alone, over 400,000 deaths and $50 billion in medical costs annually are directly attributed to smoking. Accumulated evidence indicates that nicotine is the component of tobacco smoke that leads to addiction, but the means by which nicotine produces addiction remain unclear. Nicotine is less effective as a positive reinforcer than other drugs of abuse in non-dependent animals. Nevertheless, nicotine-withdrawal symptoms, including depressed mood, anxiety, irritability and craving in dependent subjects may contribute to the addictive liability of nicotine. We show here that spontaneous nicotine withdrawal in rats resulted in a significant decrease in brain reward function, as measured by elevations in brain reward thresholds, which persisted for four days. Further, systemic injections of a competitive nicotinic-receptor antagonist led to a dose-dependent increase in brain reward thresholds in chronic nicotine-treated rats. The decreased function in brain reward systems during nicotine withdrawal is comparable in magnitude and duration to that of other major drugs of abuse, and may constitute an important motivational factor that contributes to craving, relapse and continued tobacco consumption in humans.

Escape from the extremely aversive opiate withdrawal symptoms powerfully motivates compulsive drug-seeking and drug-taking behaviors. The corticotropin-releasing factor (CRF) system is hypothesized to mediate the motivational properties of drug dependence. CRF signaling is transmitted by two receptor pathways, termed CRF1 and CRF2. To investigate the role for the CRF2 receptor pathway in somatic opiate withdrawal, in the present study we used genetically engineered mice deficient in the CRF2 receptor (CRF2−/−). We employed a novel, clinically relevant mouse model of ‘spontaneous’ opiate withdrawal as well as a classical opioid receptor antagonist (naloxone)-precipitated opiate withdrawal paradigm. To induce opiate dependence, mice were treated with intermittent escalating morphine doses (20–100 mg/kg, i.p.). We found that 8–128 h after the last opiate injection, CRF2−/− mice showed decreased levels of major somatic signs of spontaneous opiate withdrawal, such as paw tremor and wet dog shake, as compared to wild-type mice. Similarly, challenge with naloxone 2 h after the last morphine injection induced lower levels of paw tremor and wet dog shake in CRF2−/− mice as compared to wild-type mice. Despite the differences in somatic signs, wild-type and CRF2−/− mice displayed similar plasma corticosterone responses to opiate dosing and withdrawal, indicating a marginal role for the hypothalamus–pituitary–adrenal axis in the CRF2 receptor mediation of opiate withdrawal. Our results unravel a novel role for the CRF2 receptor pathway in opiate withdrawal. The CRF2 receptor pathway might be a critical target of therapies aimed at alleviating opiate withdrawal symptoms and reducing relapse to drug intake. PMID:18288089

Depression and anxiety disorders are more common in women than men, and little is known about the neurobiological mechanisms that contribute to this disparity. Recent data suggest that stress-induced changes in neurotrophins have opposing effects on behavior by acting in different brain networks. Social defeat has been an important approach for understanding neurotrophin action, but low female aggression levels in rats and mice have limited the application of these methods primarily to males. We examined the effects of social defeat in monogamous California mice (Peromyscus californicus), a species in which both males and females defend territories. We demonstrate that defeat stress increases mature brain-derived neurotrophic factor (BDNF) protein but not mRNA in the bed nucleus of the stria terminalis (BNST) in females but not males. Changes in BDNF protein were limited to anterior subregions of the BNST, and there were no changes in the adjacent nucleus accumbens (NAc). The effects of defeat on social withdrawal behavior and BDNF were reversed by chronic, low doses of the antidepressant sertraline. However, higher doses of sertraline restored social withdrawal and elevated BDNF levels. Acute treatment with a low dose of sertraline failed to reverse the effects of defeat. Infusions of the selective tyrosine-related kinase B receptor (TrkB) antagonist ANA-12 into the anterior BNST specifically increased social interaction in stressed females but had no effect on behavior in females naïve to defeat. These results suggest that stress-induced increases in BDNF in the anterior BNST contribute to the exaggerated social withdrawal phenotype observed in females.

Pre-clinical studies show that, following chronic opioid exposure, oxytocin neurons exhibit over-excitation upon withdrawal, causing an increase in oxytocin brain and plasma levels. Relevant clinical data on humans are scarce. This study investigates the opioid withdrawal stress effect on oxytocin plasma levels in humans. We evaluated 57 male chronic heroin users in a residential detoxification program. We determined plasma oxytocin levels by ELISA and measured the stress effects of withdrawal using the COWS scale for opioid withdrawal, the VAS scale for craving, and the Hamilton scales for anxiety and depression on the second day of admission. Out of the 57 patients enrolled in the study, 27 completed the 21-day program, while the remaining 30 dropped out prior to completion. Plasma oxytocin levels were significantly higher in those individuals who dropped out than in those who completed the program. Participants who dropped out at some stage scored higher in the COWS, VAS-Craving, and Hamilton-anxiety scales, indicating a higher stress and explaining the higher oxytocin levels. In addition, plasma oxytocin levels correlated positively with the scores achieved in the COWS and Hamilton-anxiety scales. Higher withdrawal stress levels are associated with higher plasma oxytocin levels and early treatment discharge.

Burning mouth syndrome (BMS) can be defined as burning pain or dysesthesia on the tongue and/or other sites of the oral mucosa without a causative identifiable lesion. The discomfort is usually of daily recurrence, with a higher incidence among people aged 50 to 60 years, affecting mostly the female sex and diminishing their quality of life. The aim of this study was to evaluate the association between several pathogenic factors and burning mouth syndrome. 736 medical records of patients diagnosed of burning mouth syndrome and 132 medical records for the control group were studied retrospectively. The study time span was from January 1990 to December 2014. The protocol included: sex, age, type of oral discomfort and location, among other factors. Analysis of the association between pathogenic factors and BMS diagnosis revealed that only 3 factors showed a statistically significant association: triggers (P=.003), parafunctional habits (P=.006), and oral hygiene (P=.012). There were neither statistically significant differences in BMS incidence between sex groups (P=.408) nor association of BMS with the pathogenic factors of substance abuse (P=.915), systemic pathology (P=.685), and dietary habits (P=.904). Parafunctional habits like bruxism and abnormal movements of tongue and lips can explain the BMS main symptomatology. Psychological aspects and systemic factors should be always considered. As a multifactorial disorder, the treatment of BMS should be executed in a holistic way. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Withdrawal categories include: irrigation, water supply, livestock, thermoelectric-power generation, domestic and commercial, and industrial and mining. Withdrawal data are aggregated by county, major aquifer, and principal river basin. Only the four major categories of irrigation, water supply, livestock, and thermoelectric-power generation are illustrated in this report, although data for all categories are tabulated. The U.S. Geological Survey (USGS) established the National Water-Use Information Program in 1977 to collect uniform, current, and reliable information on water use. The Oklahoma District of the USGS and the Oklahoma Water Resources Board participate in a cooperative program to collect and publish water-use information for Oklahoma. Data contained in this report were made available through the cooperative program.

Anxiety has been indicated as one of the main symptoms of the cocaine withdrawal syndrome in human addicts and severe anxiety during withdrawal may potentially contribute to relapse. As alterations in noradrenergic transmission in limbic areas underlie withdrawal symptomatology for many drugs of abuse, the present study sought to determine the effect of cocaine withdrawal on beta-adrenergic receptor (beta(1) and beta(2)) expression in the amygdala. Male Sprague Dawley rats were administered intraperitoneal (i.p.) injections of cocaine (20 mg/kg) once daily for 14 days. Two days following the last cocaine injection, amygdala brain regions were micro-dissected and processed for Western blot analysis. Results showed that beta(1)-adrenergic receptor, but not beta(2)-adrenergic receptor expression was significantly increased in amygdala extracts of cocaine-withdrawn animals as compared to controls. This finding motivated further studies aimed at determining whether treatment with betaxolol, a highly selective beta(1)-adrenergic receptor antagonist, could ameliorate cocaine withdrawal-induced anxiety. In these studies, betaxolol (5 mg/kg via i.p. injection) was administered at 24 and then 44 h following the final chronic cocaine administration. Anxiety-like behavior was evaluated using the elevated plus maze test approximately 2 h following the last betaxolol injection. Following behavioral testing, betaxolol effects on beta(1)-adrenergic receptor protein expression were examined by Western blotting in amygdala extracts from rats undergoing cocaine withdrawal. Animals treated with betaxolol during cocaine withdrawal exhibited a significant attenuation of anxiety-like behavior characterized by increased time spent in the open arms and increased entries into the open arms compared to animals treated with only saline during cocaine withdrawal. In contrast, betaxolol did not produce anxiolytic-like effects in control animals treated chronically with saline. Furthermore

Methods: Vascular endothelial growth factor165 (VEGF165), tumour necrosis factor α (TNFα), and interleukin 1ß (IL1ß) were measured by enzyme linked immunosorbent assay (ELISA) in serum samples from three patients with RS3PE syndrome. As controls, serum samples from 26 healthy volunteers, 12 patients with rheumatoid arthritis, 10 patients with systemic lupus erythematosus, 13 patients with polymyositis/dermatomyositis, 13 patients with vasculitis syndrome, and 6 patients with mixed connective tissue disease were also analysed. Synovial hypervascularity of patients with RS3PE syndrome was estimated by rate of enhancement (E-rate) in a dynamic MRI study. Results: Serum concentrations of VEGF165 (mean (SD) 2223.3 (156.3) pg/ml) were significantly higher in patients with active RS3PE syndrome than in controls before corticosteroid treatment. TNFα and IL1ß levels were similar in patients and controls. Synovial hypervascularity in affected joints and subcutaneous oedema decreased during corticosteroid treatment, in parallel with the fall in serum VEGF165. Conclusions: VEGF promotes synovial inflammation and vascular permeability in patients with RS3PE syndrome, suggesting that RS3PE can be classified as a VEGF associated disorder. PMID:16227418

Metabolic Vascular Syndrome: New Insights into a Multidimensional Network of Risk Factors and Diseases.

PubMed

Scholz, Gerhard H; Hanefeld, Markolf

2016-10-01

Since 1981, we have used the term metabolic syndrome to describe an association of a dysregulation in lipid metabolism (high triglycerides, low high-density lipoprotein cholesterol, disturbed glucose homeostasis (enhanced fasting and/or prandial glucose), gout, and hypertension), with android obesity being based on a common soil (overnutrition, reduced physical activity, sociocultural factors, and genetic predisposition). We hypothesized that main traits of the syndrome occur early and are tightly connected with hyperinsulinemia/insulin resistance, procoagulation, and cardiovascular diseases. To establish a close link between the traits of the metabolic vascular syndrome, we focused our literature search on recent original work and comprehensive reviews dealing with the topics metabolic syndrome, visceral obesity, fatty liver, fat tissue inflammation, insulin resistance, atherogenic dyslipidemia, arterial hypertension, and type 2 diabetes mellitus. Recent research supports the concept that the metabolic vascular syndrome is a multidimensional and interactive network of risk factors and diseases based on individual genetic susceptibility and epigenetic changes where metabolic dysregulation/metabolic inflexibility in different organs and vascular dysfunction are early interconnected. The metabolic vascular syndrome is not only a risk factor constellation but rather a life-long abnormality of a closely connected interactive cluster of developing diseases which escalate each other and should continuously attract the attention of every clinician.

Socially withdrawn children frequently refrain from social activities in the presence of peers. The lack of social interaction in childhood may result from a variety of causes, including social fear and anxiety or a preference for solitude. From early childhood through to adolescence, socially withdrawn children are concurrently and predictively at risk for a wide range of negative adjustment outcomes, including socio-emotional difficulties (e.g., anxiety, low self-esteem, depressive symptoms, and internalizing problems), peer difficulties (e.g., rejection, victimization, poor friendship quality), and school difficulties (e.g., poor-quality teacher-child relationships, academic difficulties, school avoidance). The goals of the current review are to (a) provide some definitional, theoretical, and methodological clarity to the complex array of terms and constructs previously employed in the study of social withdrawal; (b) examine the predictors, correlates, and consequences of child and early-adolescent social withdrawal; and (c) present a developmental framework describing pathways to and from social withdrawal in childhood.

Background About 10 million children worldwide live or work on the street. International reports estimate the prevalence of substance use among street children to be between 25% - 90%, which is who were referredntal disorders and high-risk behaviors. Objectives The objective of this study was to report the outcomes of assisted withdrawal of opioid-dependent vulnerable children and adolescents who were referred to child and adolescent psychiatric ward of Ali Ebne Abitaleb hospital, an academic hospital in Zahedan city. Methods Clinical chart abstractions were performed on a convenience sample of 40 serial opioid-dependent street children and adolescents (mean age: 11.14 ± 3.6 years) who were referred to child and adolescent psychiatric ward of Ali Ebne Abitaleb treatment and research center from November 2014 to May 2015. The demographic data, drug use history, comorbid physical and psychiatric conditions, symptomatology of opioid withdrawal syndrome, pharmacotherapies and psychosocial services, length of hospital stay, and any adverse events were extracted from the patients’ files using a checklist developed by the authors. Results Twenty-four (60%) patients were male, and 16 (40%) were female. The main drug used by all patients was opioids. Heroin Kerack (which has a street name of crystal in southeast Iran) was the most common (75%) drug of use, followed by opium (10%) and opium residue (7.5%). None of the participants self-reported using injected drugs. The high rate of a lack of eligibility for guardianship was documented among parents (87.5%) mainly due to their use of illegal drugs. Musculoskeletal pain and diarrhea were the most common withdrawal symptoms of the patients upon admission. The mean length of stay was 10.8 (± 7.30) days, and no significant adverse events were reported during the symptomatic treatment of opioid withdrawal syndrome. Conclusions To our knowledge, this is the first study to report on the safety and feasibility of inpatient

Case report. Pediatric intensive care unit of a children's hospital. Ten-month-old with Noonan syndrome and massive gastrointestinal bleeding resulting in severe hypovolemic shock. Recombinant factor VIIa was used in this patient's severe bleeding associated with Noonan syndrome after no other supportive measures were successful. Recombinant Factor VIIa significantly decreased the patient's bleeding and allowed his hypovolemic shock to improve. Ultimately, the patient made a complete recovery. Noonan syndrome has a constellation of both cardiac and noncardiac malformations including an increased risk of bleeding, and recombinant factor VIIa is an important agent in the treatment of significant bleeding.

Cognitive decline and dementia have a deep impact on the health and quality of life of older subjects and their caregivers. Since the therapeutic options currently available have demonstrated limited efficacy, the search for preventive strategies for cognitive decline and dementia are mandatory. A possible role of lifestyle-related factors was recently proposed for age-related changes of cognitive function, predementia syndromes and the cognitive decline of degenerative (Alzheimer's disease [AD]) or vascular origin. At present, cumulative evidence suggests that vascular risk factors may be important in the development of mild cognitive impairment (MCI), dementia and AD. Moderate alcohol drinking has been proposed as a protective factor against MCI and dementia in several longitudinal studies, but contrasting findings also exist. The Mediterranean diet could therefore be an interesting model with which to further study the association between dietary patterns and cognitive functioning, given the suggested role of many components of this diet (monounsaturated fatty acids, polyunsaturated fatty acids, cereals and red wine) in contrasting cognitive impairment and dementia. The association between low education and predementia and dementia syndromes is supported by the majority of studies, but very few studies have investigated whether this association may be attributed with lifestyle factors that covary with education. Studies in the literature seem to identify in physical exercise one promising strategy in decreasing cognitive decline, but some of the limitations of these studies do not allow us to draw definite conclusions. At present, in older subjects, healthy diets, antioxidant supplements, the prevention of nutritional deficiencies, and moderate physical activity could be considered the first line of defense against the development and progression of predementia and dementia syndromes. However, in most cases, these were only observational studies, and results are

Increased CRF signaling in a ventral tegmental area-interpeduncular nucleus-medial habenula circuit induces anxiety during nicotine withdrawal

Increased anxiety is a predominant withdrawal symptom in abstinent smokers, yet the neuroanatomical and molecular bases underlying it are unclear. Here, we show that withdrawal-induced anxiety increases activity of neurons in the interpeduncular intermediate (IPI), a subregion of the interpeduncular nucleus (IPN). IPI activation during nicotine withdrawal was mediated by increased corticotropin releasing factor (CRF) receptor-1 expression and signaling, which modulated glutamatergic input from the medial habenula (MHb). Pharmacological blockade of IPN CRF1 receptors or optogenetic silencing of MHb input reduced IPI activation and alleviated withdrawal-induced anxiety; whereas IPN CRF infusion in mice increased anxiety. We identified a meso-interpeduncular circuit, consisting of ventral tegmental area (VTA) dopaminergic neurons projecting to the IPN, as a potential source of CRF. Knock-down of CRF synthesis in the VTA prevented IPI activation and anxiety during nicotine withdrawal. These data indicate that increased CRF receptor signaling within a VTA-IPN-MHb circuit triggers anxiety during nicotine withdrawal. PMID:25898242

Withdrawal symptoms in internet gaming disorder: A systematic review.

PubMed

Kaptsis, Dean; King, Daniel L; Delfabbro, Paul H; Gradisar, Michael

2016-02-01

Internet gaming disorder (IGD) is currently positioned in the appendix of the DSM-5 as a condition requiring further study. The aim of this review was to examine the state of current knowledge of gaming withdrawal symptomatology, given the importance of withdrawal in positioning the disorder as a behavioral addiction. A total of 34 studies, including 10 qualitative studies, 17 research reports on psychometric instruments, and 7 treatment studies, were evaluated. The results indicated that the available evidence on Internet gaming withdrawal is very underdeveloped. Internet gaming withdrawal is most consistently referred to as 'irritability' and 'restlessness' following cessation of the activity. There exists a concerning paucity of qualitative studies that provide detailed clinical descriptions of symptoms arising from cessation of internet gaming. This has arguably compromised efforts to quantify withdrawal symptoms in empirical studies of gaming populations. Treatment studies have not reported on the natural course of withdrawal and/or withdrawal symptom trajectory following intervention. It is concluded that many more qualitative clinical studies are needed, and should be prioritised, to develop our understanding of gaming withdrawal. This should improve clinical descriptions of problematic internet gaming and in turn improve the quantification of IGD withdrawal and thus treatments for harmful internet gaming.

Background: Becoming a parent is one of the most significant experiences in a woman’s life. Including substantial and long-lasting mental, social, and physical charge, the parenting experience may also be a potentially stressful and overwhelming task. Since the eighties, the notion of parental burnout syndrome has gained increasing attention, but its contextual and psychological factors need to be better identified. Aims: To investigate a large array of contextual and psychological factors associated with maternal burnout syndrome in a French community-based population in order to contribute to better operationalize the notion of parental burnout and to explore its determinants. Method: A total of 304 French-speaking mothers (mean age = 34.8 years, SD = 6.72) completed a set of questionnaires including a sociodemographic form (in order to gather general information about the mothers, their spouses, and children living at home). The Perceived Stress Scale, the Maslach Burnout Inventory adapted to parents (MBI-parental), the Hospital Anxiety and Depression Scale, the Parental Stress Index-Short Form and the Ways of Coping Checklist were used in this study. Results: Multivariate linear regression analyses revealed that scores on the MBI-parental version were strongly and positively associated with depressive and anxiety symptoms, as well as with perceived stress related to parenthood and parenting stress levels. Moreover, using the task-oriented coping style in parenthood was strongly and positively associated with personal accomplishment. Conversely, some sociodemographic characteristics were found to be negatively associated with maternal burnout: being employed, working full time and being a mother living without a coparent. Conclusion: The construct of maternal burnout syndrome seems to be linked to a conjunction of psychological and contextual factors associated with maternal exhaustion.

Inhaled corticosteroids (ICS) are widely used to manage chronic obstructive pulmonary disease (COPD). However, withdrawal of ICS generally causes various adverse effects, warranting careful management of the ICS withdrawal. Pinellia ternata, a traditional Chinese herbal medicine, has been used to treat respiratory diseases in China for centuries. Here, we investigated its role in antagonizing ICS withdrawal-induced side effects, and explored the underlying mechanisms. The rat COPD model was established using a combination of passive cigarette smoking and intratracheal instillation of lipopolysaccharide (LPS). COPD rats were treated with saline or budesonide inhalation, or with budesonide inhalation followed by saline inhalation or Pinellia ternata gavage. The number of goblet cells and the level of mucin 5AC (MUC5AC) were enhanced by budesonide withdrawal. Pinellia ternata treatment significantly blocked these effects. Further, Pinellia ternata treatment reversed budesonide withdrawal-induced increase of interleukin 1[Formula: see text] (IL-1[Formula: see text] and tumor necrosis factor [Formula: see text] (TNF-[Formula: see text]) levels in bronchoalveolar lavage fluid (BALF). Extracellular signal-regulated kinase (ERK), but neither p38 nor c-Jun N-terminal kinase (JNK), was activated by budesonide withdrawal, and the activation was blocked by Pinellia ternata treatment. The MUC5AC expression was positively correlated with goblet cell number, IL-1[Formula: see text] and TNF-[Formula: see text] levels, and ERK activity. Pinellia ternata treatment protected the airway from ICS withdrawal-induced mucus hypersecretion and airway inflammation by inhibiting ERK activation. Pinellia ternata treatment may represent a novel therapeutic strategy to prevent ICS withdrawal-induced side effects in COPD patients.

Antidepressant withdrawal symptoms are well-recognised, but their potential duration remains uncertain. We aimed to describe the characteristics of withdrawal associated with two popular classes of antidepressants, including duration. We analysed the content of a sample of posts on an antidepressant withdrawal website. We compared the characteristics of withdrawal associated with SSRIs and SNRIs, including time of onset, duration and nature of symptoms. 110 posts about SSRI withdrawal, and 63 concerning SNRI withdrawal, were analysed. The mean duration of withdrawal symptoms was significantly longer with SSRIs than SNRIs: 90.5 weeks (standard deviation, SD, 150.0) and 50.8 weeks (SD 76.0) respectively; p = 0.043). Neurological symptoms, such as 'brain zaps,' were more common among SNRI users (p = 0.023). Psychosexual/genitourinary symptoms may be more common among SSRI users (p = 0.054). The website aims to help people with antidepressant withdrawal, and is therefore likely to attract people who have difficulties. Length of prior use of antidepressants was long, with a mean of 252.2 weeks (SD 250.8). People accessing antidepressant withdrawal websites report experiencing protracted withdrawal symptoms. There are some differences in the characteristics of withdrawal associated with different classes of antidepressants.

Some occupational factors have been implicated in the development of disorders manifested as hand pain. The associations seem to be well documented in processes such as hand-arm vibration syndrome (HAVS) or writer's cramp. There are contradictory data in the literature about the relationships of trigger finger, De Quervain's tenosynovitis (DQT) and tenosynovitis of the wrist with occupational factors. In this article, we review current knowledge about clinical manifestations, case definition, implicated occupational factors, diagnosis and treatment of the most relevant hand pain disorders that have been associated with occupational factors, excluding carpal tunnel syndrome (CTS).

Drug withdrawal conceptualized as a stressor

PubMed Central

Chartoff, Elena H.; Carlezon, William A.

2015-01-01

Drug withdrawal is often conceptualized as an aversive state that motivates drug-seeking and drug-taking behaviors in humans. Stress is more difficult to define, but is also frequently associated with aversive states. Here we describe evidence for the simple theory that drug withdrawal is a stress-like state, on the basis of common effects on behavioral, neurochemical, and molecular endpoints. We also describe data suggesting a more complex relationship between drug withdrawal and stress. As one example, we will highlight evidence that, depending on drug class, components of withdrawal can produce effects that have characteristics consistent with mood elevation. In addition, some stressors can act as positive reinforcers, defined as having the ability to increase the probability of a behavior that produces it. As such, accumulating evidence supports the general principles of opponent process theory, whereby processes that have an affective valence are followed in time by an opponent process that has the opposite valence. Throughout, we identify gaps in knowledge and propose future directions for research. A better understanding of the similarities, differences, and overlaps between drug withdrawal and stress will lead to the development of improved treatments for addiction, as well as for a vast array of neuropsychiatric conditions that are triggered or exacerbated by stress.

Estimating pumping time and ground-water withdrawals using energy- consumption data

USGS Publications Warehouse

Hurr, R.T.; Litke, D.W.

1989-01-01

Evaluation of the hydrology of an aquifer requires knowledge about the volume of groundwater in storage and also about the volume of groundwater withdrawals. Totalizer flow meters may be installed at pumping plants to measure withdrawals; however, it generally is impractical to equip all pumping plants in an area with meters. A viable alternative is the use of rate-time methods. Rate-time methods may be used at individual pumping plants to decrease the data collection necessary for determining withdrawals. At sites where pumping-time measurement devices are not installed, pumping time may be determined on the basis of energy consumption and power demand. At pumping plants where energy consumption is metered, data acquired by reading of meters is used to estimate pumping time. Care needs to be taken to read these meters correctly. At pumping plants powered by electricity, the calculations need to be modified if transformers are present. At pumping plants powered by natural gas, the effects of the pressure-correction factor need to be included in the calculations. At pumping plants powered by gasoline, diesel oil, or liquid petroleum gas, the geometry of storage tanks needs to be analyzed as part of the calculations. The relation between power demand and pumping rate at a pumping plant can be described through the use of the power-consumption coefficient. Where equipment and hydrologic conditions are stable, this coefficient can be applied to total energy consumption at a site to estimate total groundwater withdrawals. Random sampling of power consumption coefficients can be used to estimate area-wide groundwater withdrawal. (USGS)

Genetic Syndromes, Maternal Diseases and Antenatal Factors Associated with Autism Spectrum Disorders (ASD).

Autism spectrum disorder (ASD) affecting about 1% of all children is associated, in addition to complex genetic factors, with a variety of prenatal, perinatal, and postnatal etiologies. In addition, ASD is often an important clinical presentation of some well-known genetic syndromes in human. We discuss these syndromes as well as the role of the more important prenatal factors affecting the fetus throughout pregnancy which may also be associated with ASD. Among the genetic disorders we find Fragile X, Rett syndrome, tuberous sclerosis, Timothy syndrome, Phelan-McDermid syndrome, Hamartoma tumor syndrome, Prader-Willi and Angelman syndromes, and a few others. Among the maternal diseases in pregnancy associated with ASD are diabetes mellitus (PGDM and/or GDM), some maternal autoimmune diseases like antiphospholipid syndrome (APLS) with anti-β2GP1 IgG antibodies and thyroid disease with anti-thyroid peroxidase (TPO) antibodies, preeclampsia and some other autoimmune diseases with IgG antibodies that might affect fetal brain development. Other related factors are maternal infections (rubella and CMV with fetal brain injuries, and possibly Influenza with fever), prolonged fever and maternal inflammation, especially with changes in a variety of inflammatory cytokines and antibodies that cross the placenta and affect the fetal brain. Among the drugs are valproic acid, thalidomide, misoprostol, and possibly SSRIs. β2-adrenergic receptor agonists and paracetamol have also lately been associated with increased rate of ASD but the data is too preliminary and inconclusive. Associations were also described with ethanol, cocaine, and possibly heavy metals, heavy smoking, and folic acid deficiency. Recent studies show that heavy exposure to pesticides and air pollution, especially particulate matter < 2.5 and 10 μm in diameter (PM2.5 and PM10) during pregnancy is also associated with ASD. Finally, we have to remember that many of the associations mentioned in this review are

Melson, Jo; Kane, Michelle; Mooney, Ruth; Mcwilliams, James; Horton, Terry

2014-01-01

Excessive alcohol consumption is the nation's third leading cause of preventable deaths. If untreated, 6% of alcohol-dependent patients experience alcohol withdrawal, with up to 10% of those experiencing delirium tremens (DT), when they stop drinking. Without routine screening, patients often experience DT without warning. Reduce the incidence of alcohol withdrawal advancing to DT, restraint use, and transfers to the intensive care unit (ICU) in patients with DT. In October 2009, the alcohol withdrawal team instituted a care management guideline used by all disciplines, which included tools for screening, assessment, and symptom management. Data were obtained from existing datasets for three quarters before and four quarters after implementation. Follow-up data were analyzed and showed a great deal of variability in transfers to the ICU and restraint use. Percentage of patients who developed DT showed a downward trend. Incidence of alcohol withdrawal advancing to DT and, in patients with DT, restraint use and transfers to the ICU. Initial data revealed a decrease in percentage of patients with alcohol withdrawal who experienced DT (16.4%-12.9%). In patients with DT, restraint use decreased (60.4%-44.4%) and transfers to the ICU decreased (21.6%-15%). Follow-up data indicated a continued downward trend in patients with DT. Changes were not statistically significant. Restraint use and ICU transfers maintained postimplementation levels initially but returned to preimplementation levels by third quarter 2012. Early identification of patients for potential alcohol withdrawal followed by a standardized treatment protocol using symptom-triggered dosing improved alcohol withdrawal management and outcomes.

Withdrawal-oriented therapy for smokers.

PubMed

Hajek, P

1989-06-01

The treatment approach of the Maudsley Hospital Smokers Clinic is described. It stems from the notion that smokers seeking help are dependent on nicotine, and that withdrawal discomfort is a major block to their success in quitting. Accordingly, therapy focuses on helping clients overcome nicotine deprivation. It uses nicotine replacement and a special format of group treatment. Details are given of preparation of clients, use of nicotine chewing gum, use of group-oriented groupwork, use of information about withdrawal, and training in withdrawal-oriented therapy. Data are presented concerning characteristics of the clientele, treatment adherence, and treatment results. A number of controversial issues are addressed, such as the optimal duration of treatment, timing of the quit date, the value of educational input, and the value of individualization of treatment goals.

2008-08-01

This study examined the association between metabolic syndrome, lifestyle behaviors, and perception and knowledge of current health and cardiovascular disease (CVD) among Asian Indians in the US. The sample comprised of 143 adult Asian Indians recruited through health fairs for survey and bioclinical measures. The prevalence of metabolic syndrome was 32%, much higher than other ethnic groups, did not vary by gender but increased with age. Respondents had high physical inactivity and poor knowledge of CVD risk factors. Dietary behavior, age, number of years lived in the US, self-rated physical and mental health and BMI were significant predictors and explained 40.1% of variance in metabolic syndrome score. Poorer physical health status had the greatest predictive influence on metabolic syndrome. Asian Indians are a high risk group for CVD.

Capsaicinoids Modulating Cardiometabolic Syndrome Risk Factors: Current Perspectives

PubMed Central

2016-01-01

Capsaicinoids are bioactive nutrients present within red hot peppers reported to cut ad libitum food intake, to increase energy expenditure (thermogenesis) and lipolysis, and to result in weight loss over time. In addition it has shown more benefits such as improvement in reducing oxidative stress and inflammation, improving vascular health, improving endothelial function, lowering blood pressure, reducing endothelial cytokines, cholesterol lowering effects, reducing blood glucose, improving insulin sensitivity, and reducing inflammatory risk factors. All these beneficial effects together help to modulate cardiometabolic syndrome risk factors. The early identification of cardiometabolic risk factors can help try to prevent obesity, hypertension, diabetes, and cardiovascular disease. PMID:27313880

2007-03-01

Asperger's syndrome has been recognized recently. Diagnosis is done by DSM-IV-TR, ICD-10 or Autistic Spectrum Diagnosis. Medical care is performed by adjustment of environmental atmosphere, educational treatment and/or medication. Patients are cured by parents or teachers who can understand their thinking or behavior pattern. Educational treatment is important to compensate the lack of "mind of theory", of integration of central nervous system and of executive functioning. Medication is applied only secondary symptoms, such as hallucinated or delusional complaints or change of mood or compulsive behavior. Some of this syndrome's patients have excellent abilities and will accomplish great achievement in adult. We need protect them from bullying or secondary social withdrawal in adolescent age.

Metabolic syndrome is becoming an important public health problem in affluent societies. To identify factors associated to metabolic syndrome in a Southern Chilean city. Using a case control design, 200 participants, aged 35 to 70 years with at least three criteria for metabolic syndrome according to the National Cholesterol Education Program (NCEP_ATPIII) and 200 subjects with less than three criteria, were studied. Both groups were compared in terms of ethnic background, educational level, family history of diabetes and coronary artery disease, menopausal status, smoking, stress and depression, physical activity, changes in body mass index in the last five years and diet. Among subjects aged more than 54 years, among males and among overweight individuals, having a Mapuche origin was a risk factor with odds ratios (OR) of 7.2; 88 and 3.9 respectively. Among subjects aged more than 54 years, among women and among overweight individuals, a family history of diabetes was a risk factor with OR of 17.7; 3.2 and 3.9 respectively. Among subjects aged more than 54 years and among women a change in body mass index of more than three points was a risk factor with OR of 12.5 and 7.4, respectively. Depression also was a risk factor among subjects aged more than 54 years (OR 3.3). Regular consumption of wine was a protective factor among participants of more than 54 years, with an OR of 0.17. The risk factors for metabolic syndrome detected in this group of participants, were having a Mapuche origin, a family history of diabetes mellitus and depression. Wine consumption was associated with a lower risk.

2018-06-01

Hematopoietic cell transplantation is a life-saving procedure, but one associated with increasing long-term cardiovascular risk requiring frequent long-term follow-up. This therapy has significantly lengthened survival in mucopolysaccharidosis type IH (Hurler syndrome), a disease with known coronary artery involvement. Metabolic syndrome-a constellation of central obesity, high blood pressure, low high-density lipoprotein cholesterol, elevated triglycerides, and fasting blood glucose-is associated with increased cardiovascular risk, and occurs when any 3 or more of these 5 components is present within a single individual. The incidence of metabolic syndrome and its components is poorly defined after transplantation for Hurler syndrome. Chart review of all long-term survivors of hematopoietic cell transplantation for Hurler syndrome ≥9 years of age for factors comprising the metabolic syndrome: obesity, high blood pressure, low high-density lipoprotein cholesterol, elevated triglycerides, and fasting blood glucose. Sixty-three patients were evaluated, 20 of whom had components of the metabolic syndrome available for review. There was no significant difference in age at transplantation, sex, number of transplants, pretransplant radiation, or percent engraftment between those with and without these data. Median follow-up after transplantation for the 20 patients with data was 14.3 years. Only 1 (5%) patient of this group fulfilled the criteria for metabolic syndrome. Fifty-three percent of the patients had 1 or more components of metabolic syndrome: the most common was high blood pressure occurring in 40%. Metabolic syndrome is uncommon in this cohort of long-term survivors of hematopoietic cell transplantation for Hurler syndrome but almost half of the patients had 1 or more components of the syndrome, with high blood pressure being the most common. Further studies are needed to develop guidelines in this diagnosis as well as other nonmalignant diseases of children

Postmenopausal women are known to have a higher prevalence of metabolic syndrome compared with premenopausal women. However, there are few studies that have investigated the effects of reproductive factors on metabolic syndrome in postmenopausal women. The objective of this study was to evaluate the association between reproductive factors and metabolic syndrome in postmenopausal women. A total of 892 postmenopausal women who participated in the 2005 Korean National Health and Nutrition Examination Survey were included. We determined an association between reproductive factors and metabolic syndrome. Using a multivariate logistic regression analysis, it was found that age at first birth was negatively associated with metabolic syndrome. Having the first baby at a later age was associated with a decreased risk of having metabolic syndrome (odds ratio, 0.95; 95% CI, 0.90-0.99). However, other reproductive factors including age at menarche, age at menopause, parity, lifetime estrogen exposure, years since menopause, number of pregnancies, history of lactation, and oral contraceptives or hormone therapy use were not associated with metabolic syndrome. Among various reproductive factors, age at first birth was negatively associated with metabolic syndrome in Korean postmenopausal women.

To evaluate the prevalence of burnout syndrome among nursing workers in intensive care units and establish associations with psychosocial factors. This descriptive study evaluated 130 professionals, including nurses, nursing technicians, and nursing assistants, who performed their activities in intensive care and coronary care units in 2 large hospitals in the city of Rio de Janeiro, Brazil. Data were collected in 2011 using a self-reported questionnaire. The Maslach Burnout Inventory was used to evaluate the burnout syndrome dimensions, and the Self Reporting Questionnaire was used to evaluate common mental disorders. The prevalence of burnout syndrome was 55.3% (n = 72). In the quadrants of the demand-control model, low-strain workers exhibited a prevalence of 64.5% of suspected cases of burnout, whereas high-strain workers exhibited a prevalence of 72.5% of suspected cases (p = 0.006). The prevalence of suspected cases of common mental disorders was 27.7%; of these, 80.6% were associated with burnout syndrome (< 0.0001). The multivariate analysis adjusted for gender, age, educational level, weekly work duration, income, and thoughts about work during free time indicated that the categories associated with intermediate stress levels - active work (OR = 0.26; 95%CI = 0.09 - 0.69) and passive work (OR = 0.22; 95%CI = 0.07 - 0.63) - were protective factors for burnout syndrome. Psychosocial factors were associated with the development of burnout syndrome in this group. These results underscore the need for the development of further studies aimed at intervention and the prevention of the syndrome.

2017-01-01

The purpose of this study was to investigate the clustering pattern of four major lifestyle risk factors-smoking, heavy drinking, poor diet, and physical inactivity-among people with metabolic syndrome in South Korea. There were 2,469 adults with metabolic syndrome aged 30 years or older available with the 5th Korean National Health and Nutrition Examination Survey dataset. We calculated the ratio of the observed to expected (O/E) prevalence for the 16 different combinations and the prevalence odds ratios (POR) of four lifestyle risk factors. The four lifestyle risk factors tended to cluster in specific multiple combinations. Smoking and heavy drinking was clustered (POR: 1.86 for male, 4.46 for female), heavy drinking and poor diet were clustered (POR: 1.38 for male, 1.74 for female), and smoking and physical inactivity were also clustered (POR: 1.48 for male). Those who were male, younger, low-educated and living alone were much more likely to have a higher number of lifestyle risk factors. Some helpful implications can be drawn from the knowledge on clustering pattern of lifestyle risk factors for more effective intervention program targeting metabolic syndrome.

Donation After Circulatory Death for Liver Transplantation: A Meta-Analysis on the Location of Life Support Withdrawal Affecting Outcomes.

2016-07-01

Liver transplantation using donation after circulatory death (DCD) donors is associated with inferior outcomes compared to donation after brain death (DBD). Prolonged donor warm ischemic time has been identified as the key factor responsible for this difference. Various aspects of the donor life support withdrawal procedure, including location of withdrawal and administration of antemortem heparin, are thought to play important roles in mitigating the effects of warm ischemia. However, a systematic exploration of these factors is important for more confident integration of these practices into a standard DCD protocol. Medline, EMBASE, and Cochrane libraries were systematically searched and 23 relevant studies identified for analysis. Donation after circulatory death recipients were stratified according to location of life support withdrawal (intensive care unit or operating theater) and use of antemortem heparin. Donation after circulatory death recipients had comparable 1-year patient survival to DBD recipients if the location of withdrawal of life support was the operating theater, but not if the location was the intensive care unit. Likewise, the inferior 1-year graft survival and higher incidence of ischemic cholangiopathy of DCD compared with DBD recipients were improved by withdrawal in operating theater, although higher rates of ischemic cholangiopathy and worse graft survival were still observed in DCD recipients. Furthermore, administering heparin before withdrawal of life support reduced the incidence of primary nonfunction of the allograft. Our evidence suggests that withdrawal in the operating theater and premortem heparin administration improve DCD liver transplant outcomes, thus allowing for the most effective usage of these valuable organs.

2011-11-01

Building on interpersonal theories of depression, the current study sought to explore whether early childhood social withdrawal serves as a risk factor for depressive symptoms and diagnoses in young adulthood. The researchers hypothesized that social impairment at age 15 would mediate the association between social withdrawal at age 5 and depression by age 20. This mediational model was tested in a community sample of 702 Australian youth followed from mother's pregnancy to youth age 20. Structural equation modeling analyses found support for a model in which childhood social withdrawal predicted adolescent social impairment, which, in turn, predicted depression in young adulthood. Additionally, gender was found to moderate the relationship between adolescent social impairment and depression in early adulthood, with females exhibiting a stronger association between social functioning and depression at the symptom and diagnostic level. This study illuminates one potential pathway from early developing social difficulties to later depressive symptoms and disorders.

2009-01-01

In 2005, the total amount of water withdrawals in Florida was estimated at 18,359 million gallons per day (Mgal/d). Saline water accounted for 11,486 Mgal/d (63 percent), and freshwater accounted for 6,873 Mgal/d (37 percent). Groundwater accounted for 4,247 Mgal/d (62 percent) of freshwater withdrawals, and surface water accounted for the remaining 2,626 Mgal/d (38 percent). Surface water accounted for nearly all (99.9 percent) saline-water withdrawals. An additional 660 Mgal/d of reclaimed wastewater was used in Florida during 2005. The largest amount of freshwater was withdrawn from Palm Beach County, and the largest amount of saline water was withdrawn from Pasco County. Fresh groundwater provided drinking water (public supplied and self-supplied) for 16.19 million people (90 percent of Florida's population), and fresh surface water provided drinking water for 1.73 million people (10 percent). The majority of groundwater withdrawals (nearly 60 percent) in 2005 was obtained from the Floridan aquifer system which is present throughout the entire State. The majority of fresh surface-water withdrawals (59 percent) came from the southern Florida hydrologic unit subregion and is associated with Lake Okeechobee and the canals in the Everglades Agricultural Area of Glades, Hendry, and Palm Beach Counties, as well as the Caloosahatchee River and its tributaries in the agricultural areas of Collier, Glades, Hendry, and Lee Counties. Overall, agricultural irrigation accounted for 40 percent of the total freshwater withdrawals (ground and surface), followed by public supply with 37 percent. Public supply accounted for 52 percent of groundwater withdrawals, followed by agricultural self-supplied (31 percent), ommercial-industrial-mining self-supplied (8.5 percent), recreational irrigation and domestic self-supplied (4 percent each), and power generation (0.5 percent). Agricultural self-supplied accounted for 56 percent of fresh surface-water withdrawals, followed by power

THE PREVALENCE OF CANNABIS WITHDRAWAL AND ITS INFLUENCE ON ADOLESCENTS’ TREATMENT RESPONSE AND OUTCOMES: A 12-MONTH PROSPECTIVE INVESTIGATION

Greene, M. Claire; Kelly, John F.

2014-01-01

Background Withdrawal, a diagnostic indicator of cannabis use disorder, is often minimized or ignored as a consequence of cannabis use, particularly among adolescents. This study aims to characterize cannabis withdrawal among adolescents in outpatient treatment for substance use disorder and evaluate the clinical significance of withdrawal as a predictor of substance-related outcomes. Methods Adolescent outpatients (N=127) reporting cannabis as their drug of choice (n=90) were stratified by presence of withdrawal and compared on demographic and clinical variables at treatment intake. Hierarchical linear models compared the effect of withdrawal on percent days abstinent (PDA) and related outcomes over a 1-year follow-up period. Results Adolescents reporting withdrawal (40%) were more likely to meet criteria for cannabis dependence, have higher levels of substance use severity, report more substance-related consequences, and have a mood disorder. Withdrawal was not associated with PDA over the follow-up period; however, this relationship was moderated by problem recognition such that adolescents reporting withdrawal and a drug problem improved at a greater rate with respect to PDA than those that didn’t recognize a problem with drugs and didn’t report withdrawal. Discussion Withdrawal is common among adolescent outpatients and is associated with a more clinically severe profile. In this sample, all adolescents reporting withdrawal met criteria for cannabis dependence, suggesting that withdrawal is a highly specific indicator of cannabis use disorder. While withdrawal doesn’t appear to be independently associated with substance use outcomes post-treatment, moderating factors such as drug problem recognition should be taken into account when formulating treatment and continuing care plans.

This article concisely summarizes data on the action of one of the principal and best known growth factors, the granulocyte colony-stimulating factor (G-CSF), in a mammalian organism exposed to radiation doses inducing acute radiation syndrome. Highlighted are the topics of its real or anticipated use in radiation accident victims, the timing of its administration, the possibilities of combining G-CSF with other drugs, the ability of other agents to stimulate endogenous G-CSF production, as well as of the capability of this growth factor to ameliorate not only the bone marrow radiation syndrome but also the gastrointestinal radiation syndrome. G-CSF is one of the pivotal drugs in the treatment of radiation accident victims and its employment in this indication can be expected to remain or even grow in the future.

2010-01-01

Background Repeated stress or administration of corticotropin-releasing factor (CRF) prior to ethanol exposure sensitizes anxiety-like behavior in adult rats. Current experiments determined whether adolescent rats were more sensitive to these challenges in sensitizing ethanol withdrawal-induced anxiety and altering CRF levels in brain during withdrawal. Methods Male adult and adolescent Sprague–Dawley rats were restraint stressed (1 hour) twice 1 week apart prior to a single 5-day cycle of ethanol diet (ED; stress/withdrawal paradigm). Other rats received control diet (CD) and three 1-hour restraint stress sessions. Rats were then tested 5, 24, or 48 hours after the final withdrawal for anxiety-like behavior in the social interaction (SI) test. In other experiments, adolescent rats were given two microinjections of CRF icv 1 week apart followed by 5-days of either CD or ED and tested in social interaction 5 hours into withdrawal. Finally, CRF immunoreactivity was measured in the central nucleus of the amygdala (CeA) and paraventricular nucleus (PVN) after rats experienced control diet, repeated ethanol withdrawals, or stress/withdrawal. Results Rats of both ages had reduced SI following the stress/withdrawal paradigm, and this effect recovered within 24 hours. Higher CRF doses were required to reduce SI in adolescents than previously reported in adults. CRF immunohistochemical levels were higher in the PVN and CeA of CD-exposed adolescents. In adolescent rats, repeated ethanol withdrawals decreased CRF in the CeA but was not associated with decreased CRF cell number. There was no change in CRF from adult treatments. Conclusions In the production of anxiety-like behavior, adolescent rats have equal sensitivity with stress and lower sensitivity with CRF compared to adults. Further, adolescents had higher basal levels of CRF within the PVN and CeA and reduced CRF levels following repeated ethanol withdrawals. This reduced CRF within the CeA could indicate increased

Acute alcohol withdrawal is associated with increased cardiovascular mortality, most likely due to cardiac arrhythmias. As the QT interval reflects the most critical phase for the generation of reentry and thus for arrhythmia, we examined QT variability in patients suffering from acute alcohol withdrawal. High resolution electrocardiographic recordings were performed in 18 male unmedicated patients suffering from acute alcohol withdrawal, 18 matched controls and 15 abstained alcoholics. From these, parameters of beat-to-beat heart rate and QT variability such as approximate entropy and QT variability index (QTvi) were calculated. Measures were correlated with the severity of withdrawal symptoms and with serum electrolyte concentrations. Heart rate and QTvi were significantly increased in acute alcohol withdrawal. Abstained alcoholics did not significantly differ from controls. While QTvi correlated with the severity of alcohol withdrawal symptoms, the mean QT interval duration showed an inverse relationship with serum potassium concentrations. Our data indicate increased QT variability and thus increased repolarization lability in acute alcohol withdrawal. This might add to the elevated risk for serious cardiac arrhythmias. In part, these changes might be related to increased cardiac sympathetic activity or low potassium, thus suggesting the latter as possible targets for adjuvant pharmacological therapy during withdrawal.

To evaluate the plasma level of 8-isoprostanes in women with polycystic ovary syndrome. To also investigate whether there is a relationship between 8-isoprostanes and several cardiovascular risk factors. A total of 125 women with polycystic ovary syndrome and 169 healthy women were enrolled in this case-control study. 8-Isoprostanes and different parameters were measured in all subjects. Patients were evaluated for the presence of polycystic ovary syndrome according to the Rotterdam Consensus Conference criteria. 8-Isoprostanes levels were significantly higher in patients with polycystic ovary syndrome (138.4 ± 104.1 pg/mL) compared with control group (68.6 ± 34.3 pg/mL) (p < 0.001). The mean of triglycerides, lipid accumulation product, C-reactive protein, homocysteine, insulin, and homeostatic model assessment for insulin resistance were significantly higher in polycystic ovary syndrome patients with high 8-isoprostanes than those with normal 8-isoprostanes (p < 0.05). The Pearson correlation analyses showed that 8-isoprostanes levels in polycystic ovary syndrome group had a positive correlation with waist circumference, triglycerides, low-density lipoprotein cholesterol, apolipoprotein B, homocysteine, insulin, homeostatic model assessment for insulin resistance. Patients with polycystic ovary syndrome have higher 8-isoprostanes levels and it is associated with several cardiovascular risk factors.

Betaxolol, a selective β1-adrenergic receptor antagonist, diminishes anxiety-like behavior during early withdrawal from chronic cocaine administration in rats

PubMed Central

Rudoy, C.A.; Van Bockstaele, E.J.

2007-01-01

Background Anxiety has been indicated as one of the main symptoms of the cocaine withdrawal syndrome in human addicts and severe anxiety during withdrawal may potentially contribute to relapse. As alterations in noradrenergic transmission in limbic areas underlie withdrawal symptomatology for many drugs of abuse, the present study sought to determine the effect of cocaine withdrawal on β-adrenergic receptor (β1 and β2) expression in the amygdala. Methods Male Sprague Dawley rats were administered intraperitoneal (i.p.) injections of cocaine (20 mg/kg) once daily for 14 days. Two days following the last cocaine injection, amygdala brain regions were micro-dissected and processed for Western blot analysis. Results showed that β1–adrenergic receptor, but not β2–adrenergic receptor expression was significantly increased in amygdala extracts of cocaine-withdrawn animals as compared to controls. This finding motivated further studies aimed at determining whether treatment with betaxolol, a highly selective β1–adrenergic receptor antagonist, could ameliorate cocaine withdrawal-induced anxiety. In these studies, betaxolol (5 mg/kg via i.p. injection) was administered at 24 and then 44 hours following the final chronic cocaine administration. Anxiety-like behavior was evaluated using the elevated plus maze test approximately 2 hours following the last betaxolol injection. Following behavioral testing, betaxolol effects on β1-adrenergic receptor protein expression were examined by Western blotting in amygdala extracts from rats undergoing cocaine withdrawal. Results Animals treated with betaxolol during cocaine withdrawal exhibited a significant attenuation of anxiety-like behavior characterized by increased time spent in the open arms and increased entries into the open arms compared to animals treated with only saline during cocaine withdrawal. In contrast, betaxolol did not produce anxiolytic-like effects in control animals treated chronically with saline

Many of the long-term complications in lung transplantations are secondary effects of immunosuppression. Corticosteroids are partially responsible for the development of osteoporosis, raised blood pressure, diabetes, muscular disorders, gastric ulcers, and other conditions. We analyzed the long-term result of steroid withdrawal in our lung transplant recipients. When respiratory function stabilized, to avoid secondary effects, steroid treatment was withdrawn in 34 of the 375 lung transplant patients in our centers We evaluated the characteristics of the donors and recipients, their compatibility, the pre, and post-steroid withdrawal complications, and type of immunosuppressant. The mean age of patients was 42 +/- 7 years and of donors, 25 +/- 9 years. The primary diseases were: 15 emphysema, six pulmonary fibrosis, 10 cystic fibrosis, and three primary pulmonary hypertension. Twenty seven patients had double lung transplants and seven single lung. The mean steroid withdrawal period was 881 +/- 237 days posttransplantation. The most frequent treatment regimen at the time of steroid withdrawal was cyclosporine, azathioprine, and minimal steroid doses. Six recipients had to be restarted on steroids one patient who required a kidney transplant, three cases due to an infectious process with a differential diagnosis of rejection, and two cases due to loss of FEV1 (forced expiratory volume in 1 s), suggestive of chronic rejection. There was an improvement in blood pressure in five patients, in plasma cholesterol and triglyceride levels in eight patients, and insulin withdrawal in two diabetic patients. Steroid treatment may be suspended 2 to 3 years, posttransplant in selected lung transplant recipients. The usual patient profile shows few rejection episodes with cyclosporine and azathioprine immunosuppression. What is notable is the low mean age of donors. Close clinical monitoring and lung function testing are of major importance in the weeks following steroid

Neonatal abstinence syndrome (NAS) is a postnatal opioid withdrawal syndrome. Factors associated with development of the syndrome are poorly understood; however, infant sex may influence the risk of NAS. Our objective was to determine if infant sex was associated with the development or severity of the syndrome in a large population-based cohort. This retrospective cohort study used vital statistics and prescription, outpatient, and inpatient administrative data for mothers and infants enrolled in the Tennessee Medicaid program between 2009 and 2011. Multivariable logistic regression models were used to evaluate the association between male sex and diagnosis of NAS, accounting for potential demographic and clinical confounders. NAS severity, as evidenced by hospital length of stay, was modeled by using negative binomial regression. Of 102 695 infants, 927 infants were diagnosed with NAS (484 male subjects and 443 female subjects). Adjustments were made for the following: maternal age, race, and education; maternal hepatitis C infection, anxiety, or depression; in utero exposure to selective serotonin reuptake inhibitors and cigarettes; infant birth weight, small for gestational age, and year; and the interaction between opioid type and opioid amount. Male infants were more likely than female infants to be diagnosed with NAS (adjusted odds ratio, 1.18 [95% confidence interval, 1.05-1.33]) and NAS requiring treatment (adjusted odds ratio, 1.24 [95% confidence interval, 1.04-1.47]). However, there was no sex-based difference in severity for those diagnosed with NAS. Treatment of NAS should be tailored to an infant's individual risk for the syndrome. Clinicians should be mindful that male sex is an important risk factor in the diagnosis of NAS. Copyright © 2017 by the American Academy of Pediatrics.

Excellent retention in Huntington disease (HD) clinical trials is essential for testing new therapies. The stage of disease, cognitive status, and availability of a care partner may influence retention in HD clinical trials. We sought to analyze reasons for early withdrawal in three HD clinical trials, and evaluated if either baseline characteristics or follow-up assessments were associated with time to withdrawal. Analyses of participant withdrawal were performed for three randomized, double-blind, placebo-controlled trials including the CARE-HD (coenzyme Q10 and remacemide in HD, n = 347), DOMINO (pilot study of minocycline in HD, n = 114), and 2CARE (coenzyme Q10 in HD, n = 609) trials. Reasons for withdrawal were obtained by review of textual data in the study databases. Participant demographic and clinical characteristics were analyzed as potential predictors of time to withdrawal using Cox-proportional hazards models. Estimated probabilities of withdrawal at 12 months were 2.9% for CARE-HD, 10.5% for DOMINO, and 5.9% for 2CARE. The top reasons for withdrawal (202 in total), expressed as mean percentage across the three trials, were loss to follow-up (23.2%), death (15.9%), and loss of interest/desire to participate (15.2%). Baseline and time-dependent variables associated with time to withdrawal were mainly motor, behavioral, and functional scores. Age, gender, ethnicity, and educational level were not associated with time to withdrawal in any of the three studies. The estimated withdrawal probability at 12 months ranged from 2.9% to 10.5% in the three HD trials considered here. A possible strategy to improve retention of participants in future HD clinical trials is to enroll individuals with higher baseline functional and behavioral status.

Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. To assess the effectiveness and safety of using a sedative compared to a non-opiate control for NAS due to withdrawal from opiates, and to determine which type of sedative is most effective and safe. The standard search strategy of the Neonatal Review Group was used. This update included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2005), MEDLINE 1966-March 2005 and abstracts of conference proceedings. Trials enrolling infants with NAS born to mothers with an opiate dependence, with > 80% follow up and using random or quasi-random allocation to sedative or control. Control could include another sedative or non-pharmacological treatment. Each author assessed study quality and extracted data independently. Primary outcomes included treatment failure (failure to achieve symptom control or use of additional drug treatment), seizure occurrence, mortality and neurodevelopment. Treatment effect was expressed using (RR), risk difference (RD), mean difference (MD) and weighted mean difference (WMD). Meta-analysis was performed using a fixed effect model. Six studies enrolling a total of 305 patients met inclusion criteria (Coyle 2002; Finnegan 1984; Kahn 1969; Kaltenbach 1986; Khoo 1995; Madden 1977); however, two (Finnegan 1984; Kaltenbach 1986) may be sequential reports that include some identical patients. Methodological concerns included the use of quasi-random allocation methods in four studies, and sizeable, largely unexplained differences in reported numbers allocated to each group in three studies. Phenobarbitone compared to supportive care alone has not been shown to reduce treatment failure or

To determine the relationship between cerebro vascular disease and pseudoexfoliation syndrome. This cross-sectional case control study consisted of 50 patients with ischemic-type cerebro vascular disease and 50 control subjects. All subjects were investigated for diabetes mellitus and hypertension status and underwent a detailed ophthalmic examination. A diagnosis of pseudoexfoliation syndrome was made if characteristic greyish particulate matter was found on the anterior lens capsule after pupillary dilatation by slit-lamp examination. All subjects were compared in terms of pseudoexfoliation syndrome, diabetes mellitus, and hypertension. Pearson Chi Square and Student's t test were used for statistical analysis. Logistic regression analyses of the risk factors between groups were also made. The presence of pseudoexfoliation syndrome was significantly higher in patients with cerebro vascular disease when compared to the control subjects (p = 0.02). The frequency of diabetes mellitus was similar between the two groups. Arterial hypertension was significantly more frequent in the patient group when compared to the control subjects (p < 0.01). The logistic regression analysis showed that both pseudoexfoliation syndrome and hypertension were significantly associated with cerebro vascular disease. In the present study, we found that pseudoexfoliation syndrome frequency was found to be higher in patients with cerebro vascular disease than in control subjects. A slit-lamp examination of the eye could be an important marker that indicates the risk of cerebro vascular disease. We recommend an evaluation of all subjects with pseudoexfoliation syndrome for the presence of cerebro vascular disease. Longitudinal studies with larger populations are needed to confirm this relationship.

Background & Aims Hepatic production and release of endothelin 1 plays a central role in experimental hepatopulmonary syndrome after common bile duct ligation by stimulating pulmonary endothelial nitric oxide production. In thioacetamide-induced nonbiliary cirrhosis, hepatic endothelin 1 production and release do not occur, and hepatopulmonary syndrome does not develop. However, the source and regulation of hepatic endothelin 1 after common bile duct ligation are not fully characterized. We evaluated the sources of hepatic endothelin 1 production after common bile duct ligation in relation to thioacetamide cirrhosis and assessed whether transforming growth factor β1 regulates endothelin 1 production. Methods Hepatopulmonary syndrome and hepatic and plasma endothelin 1 levels were evaluated after common bile duct ligation or thioacetamide administration. Cellular sources of endothelin 1 were assessed by immunohistochemistry and laser capture microdissection of cholangiocytes. Transforming growth factor β1 expression and signaling were assessed by using immunohistochemistry and Western blotting and by evaluating normal rat cholangiocytes. Results Hepatic and plasma endothelin 1 levels increased and hepatopulmonary syndrome developed only after common bile duct ligation. Hepatic endothelin 1 and transforming growth factor β1 levels increased over a similar time frame, and cholangiocytes were a major source of each peptide. Transforming growth factor β1 signaling in cholangiocytes in vivo was evident by increased phosphorylation and nuclear localization of Smad2, and hepatic endothelin 1 levels correlated directly with liver transforming growth factor β1 and phosphorylated Smad2 levels. Transforming growth factor β1 also stimulated endothelin 1 promoter activity, expression, and production in normal rat cholangiocytes. Conclusions Cholangiocytes are a major source of hepatic endothelin 1 production during the development of hepatopulmonary syndrome after common

The emerging dimensional approach to classification and treatment of psychiatric disorders calls for better understanding of diagnosis-related variations in psychiatric syndromes and for proper validation of psychometric scales used for the evaluation of those syndromes. This study tested the hypothesis that negative and depressive syndromes as measured by the Positive and Negative Syndrome Scale (PANSS) are consistent across different diagnoses. We administered the PANSS to subjects with schizophrenia (n = 305), organic brain disease (OBD, n = 66) and major depressive disorder (MDD, n = 75). Confirmatory factor analysis (CFA) was used to establish if the PANSS items for negative symptoms and for depression fit the hypothesized factor structure and if the item factor loadings were similar among the diagnostic groups. The negative and depressive symptom subscales fit well according to a variety of fit indexes for all groups individually after some modest model modification. However, multisample modeling procedures indicated that the pattern of factor loadings was significantly different among the groups in most cases. The results of this study indicate diagnosis-related variations in the negative and depressive syndrome dimensions in schizophrenia, OBD and MDD. These results also validate limited use of the PANSS for evaluation of negative and depressive syndromes in disorders other than schizophrenia. Larger studies are warranted to further evaluate clinical and nosologic significance of diagnostic categories, dimensions and structures of psychiatric syndromes. 2009 S. Karger AG, Basel.

Mechanisms and environmental factors that underlying the intensification of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy)-induced serotonin syndrome in rats

2014-01-01

Rationale Illicit use of MDMA (3,4-methylenedioxymethamphetamine; Ecstasy) may cause a mild or severe form of the serotonin syndrome. The syndrome intensity is not just influenced by drug doses but also by environmental factors. Objectives Warm environmental temperatures and physical activity are features of raves. The purpose of this study was to assess how these two factors can potentially intensify the syndrome. Methods Rats were administered MDMA at doses of 0.3, 1 or 3 mg/kg, and examined in the absence or presence of warm temperature and physical activity. The syndrome intensity was estimated by visual scoring for behavioral syndrome and also instrumentally measuring changes in symptoms of the syndrome. Results Our results showed that MDMA at 3 mg/kg, but not 0.3 or 1 mg/kg, caused a mild serotonin syndrome in rats. Each environmental factor alone moderately intensified the syndrome. When the two factors were combined, the intensification became more severe than each factor alone highlighting a synergistic effect. This intensification was blocked by the 5-HT2A receptor antagonist M100907, competitive NMDA receptor antagonist CGS19755, autonomic ganglionic blocker hexamethonium, and the benzodiazepine-GABAA receptor agonist midazolam, but not by the 5-HT1A receptor antagonist WAY100635 or nicotinic receptor antagonist methyllycaconitine. Conclusions Our data suggest that, in the absence of environmental factors, the MDMA-induced syndrome is mainly mediated through the serotonergic transmission (5HT-dependent mechanism), and therefore, is relatively mild. Warm temperature and physical activity facilitate serotonergic and other neural systems such as glutamatergic and autonomic transmissions, resulting in intensification of the syndrome (non-5HT mechanisms).

Ivahnenko, Tamara; Flynn, Jennifer L.

2010-01-01

The future health and economic welfare of the people and environment of Colorado depend on a continuous supply of fresh water. Detailed, comprehensive information on the use of water from Colorado's diverse surface-water and groundwater resources is important to water managers and planners by providing information they need to quantify current stresses and estimate and plan for future water needs. As part of the U.S. Geological Survey's (USGS) National Water Use Information Program (NWUIP), Statewide water withdrawal and water-use data have been collected or estimated and summarized in this report by county and by four-digit hydrologic unit code for the following seven water-use categories: irrigation (crop and golf course), public supply, self-supplied domestic, self-supplied industrial, livestock, mining, and thermoelectric power generation. A summary for instream water use for hydroelectric power generation also is included. This report is published in cooperation with the Colorado Water Conservation Board. In 2005, an estimated 13,581.22 million gallons per day (Mgal/d) was withdrawn from groundwater and surface-water sources in Colorado for the seven water-use categories. Withdrawals from surface water represented about 11,035 Mgal/d, or 81.3 percent of the total, whereas withdrawals from groundwater sources represented an estimated 2,546 Mgal/d or 18.7 percent of the total. Irrigation (combined crop and golf course) totaled 12,362.49 Mgal/d or 91 percent of the total water withdrawals in the State of Colorado. Crop irrigation accounted for 99.7 percent (12,321.85 Mgal/d) of the irrigation, whereas the 243 turf golf courses in Colorado accounted for 0.3 percent (40.64 Mgal/d) of the total irrigation water withdrawals. Total withdrawals for the other water-use categories were public supply, 864.17 Mgal/d; self-supplied domestic, 34.43 Mgal/d; self-supplied industrial, 142.44 Mgal/d; livestock, 33.06 Mgal/d; mining, 21.42 Mgal/d (includes both fresh and saline

To describe a series of patients with heart failure supported with a ventricular assist device (VAD) who requested (or whose surrogates requested) withdrawal of VAD support and the legal and ethical aspects pertaining to these requests. We retrospectively reviewed the medical records of patients at Mayo Clinic, Rochester, MN, from March 1, 2003, through January 31, 2009, who requested (or whose surrogates requested) withdrawal of VAD support and for whom the requests were fulfilled. We then explored the legal and ethical permissibility of carrying out such requests. The median age of the 14 patients identified (13 men, 1 woman) was 57 years. Requests were made by 2 patients and 12 surrogates. None of the patients' available advance directives mentioned the VAD. For 11 patients, multidisciplinary care conferences were held before withdrawal of VAD support. Only 1 patient had an ethics consultation. All 14 patients died within 1 day of withdrawal of VAD support. Patients have the right to refuse or request the withdrawal of any unwanted treatment, and we argue that this right extends to VAD support. We also argue that the cause of death in these cases is the underlying heart disease, not assisted suicide or euthanasia. Therefore, patients with heart failure supported with VADs or their surrogates may request withdrawal of this treatment. In our view, carrying out such requests is permissible in accordance with the principles that apply to withdrawing other life-sustaining treatments.

Huggard, Dean; Stack, Tom; Satas, Saulius; Gorman, Clodagh O

2015-10-27

Donohue syndrome is a rare autosomal recessive condition caused by severe loss-of-function mutations in the insulin receptor (INSR) gene. The diagnosis is made on clinical, biochemical and genetic grounds. Mutations are found on chromosome 19p13.2, and code for mutations in the INSR gene. Treatment is challenging and often unsuccessful, and relies on maintaining normoglycaemia and avoiding fasting; in some patients, recombinant human insulin-like growth factor (rhIGF-1) has been trialled. The prognosis is poor, with most babies dying in infancy. Ethically, it is important to consider the benefit versus burden of treatment, the quality of life of the surviving patient and the parents' wishes, when making decisions regarding withholding or withdrawing care. 2015 BMJ Publishing Group Ltd.

Rett syndrome and a history of seizures were in terminal remission at last contact, only 74 (12% of those with a history of epilepsy) were seizure free and off anti-seizure medication. When studied longitudinally, point prevalence of active seizures is relatively low in Rett syndrome, although lifetime risk of epilepsy is higher than previously reported. While daily seizures are uncommon in Rett syndrome, prolonged remission is less common than in other causes of childhood onset epilepsy. Complete remission off anti-seizure medications is possible, but future efforts should be directed at determining what factors predict when withdrawal of medications in those who are seizure free is propitious.

2006-01-01

Depression is common in autism and Asperger syndrome, but despite this, there has been little research into this issue. This review considers the current literature on the prevalence, presentation, treatment and assessment of depression in autism and Asperger syndrome. There are diagnostic difficulties when considering depression in autism and Asperger syndrome, as the characteristics of these disorders, such as social withdrawal and appetite and sleep disturbance, are also core symptoms of depression. Impaired verbal and non-verbal communication can mask the symptoms of depression. Symptoms associated with autism and Asperger syndrome such as obsessionality and self-injury may be increased during an episode of depression. There is a clear need to develop specific tools both for diagnostic purposes and for measurement of depression in autism and Asperger syndrome in order to help alleviate the distress caused by this treatable illness.

Papp, Lauren M; Kouros, Chrystyna D; Cummings, E Mark

2009-06-01

The present study extended laboratory-based findings of demand-withdraw communication into marital conflict in the home and further explored its linkages with spousal depression. U.S. couples (N = 116) provided diary reports of marital conflict and rated depressive symptoms. Hierarchical linear modeling results indicated that husband demand-wife withdraw and wife demand-husband withdraw occurred in the home at equal frequency, and both were more likely to occur when discussing topics that concerned the marital relationship. For both patterns, conflict initiator was positively linked to the demander role. Accounting for marital satisfaction, both demand-withdraw patterns predicted negative emotions and tactics during marital interactions and lower levels of conflict resolution. Spousal depression was linked to increased likelihood of husband demand-wife withdraw.

Previous trials on acupuncture in alcohol addiction were in outpatients and focused on relapse prevention. Rates of dropout were high and interpretation of results difficult. We compared auricular laser and needle acupuncture with sham laser stimulation in reducing the duration of alcohol withdrawal. Inpatients undergoing alcohol withdrawal were randomly allocated to laser acupuncture (n = 17), needle acupuncture (n = 15) or sham laser stimulation (n = 16). Attempts were made to blind patients, therapists and outcome assessors, but this was not feasible for needle acupuncture. The duration of withdrawal symptoms (as assessed using a nurse-rated scale) was the primary outcome; the duration of sedative prescription was the secondary outcome. Patients randomized to laser and sham laser had identical withdrawal symptom durations (median 4 days). Patients randomized to needle stimulation had a shorter duration of withdrawal symptoms (median 3 days; P = 0.019 versus sham intervention), and tended to have a shorter duration of sedative use, but these differences diminished after adjustment for baseline differences. The data from this pilot trial do not suggest a relevant benefit of auricular laser acupuncture for alcohol withdrawal. A larger trial including adequate sham interventions is needed, however, to reliably determine the effectiveness of any type of auricular acupuncture in this condition.

Mental health consequences of exercise withdrawal: A systematic review.

PubMed

Weinstein, Ali A; Koehmstedt, Christine; Kop, Willem J

2017-11-01

A sedentary lifestyle has been associated with mental health disorders. Many medical conditions result in the cessation of exercise, which may increase the risk of developing mental health problems. The purpose of this article is to systematically review the literature examining the effects of exercise withdrawal on mental health. Literature was searched using PubMed, PsycINFO, and SPORTdiscus for studies that experimentally manipulated the withdrawal of exercise and included mental health as outcome measure. A total of 19 studies met inclusion criteria (total N=689 with 385 individuals participating in an exercise withdrawal condition). Exercise withdrawal consistently resulted in increases in depressive symptoms and anxiety. Other mental health outcomes were investigated infrequently. Severe mental health issues requiring clinical intervention after experimentally controlled exercise withdrawal was rare. Heterogeneity in methods and outcomes was observed, especially in terms of the duration of exercise withdrawal (range 1 to 42days, median=7days), with stronger effects if exercise withdrawal exceeded 2weeks. Experimentally controlled exercise withdrawal has adverse consequences for mental health. These observations in healthy individuals may help to understand the onset of mental health problems in response to acute and chronic medical conditions associated with reduced physical activity. Future research is needed to investigate potential mechanisms explaining the adverse mental health consequences of cessation of exercise that will provide new targets for clinical interventions.

The effect of environmental factors on morphine withdrawal in C57BL/6J mice: running wheel access and group housing.

PubMed

Balter, Rebecca E; Dykstra, Linda A

2012-11-01

There is evidence to suggest that the rewarding effects of drugs of abuse can be altered by environmental manipulations such as housing conditions and access to running wheels. There is less information about how these environmental manipulations alter withdrawal behaviors following the termination of chronic drug administration. The objective of this study is to examine the effects of access to running wheels and group housing on spontaneous morphine withdrawal. C57BL/6J mice were assigned to one of the three housing conditions: wheel access (singly housed), no wheels (singly housed), or group-housed (no wheels). Mice received 30 or 56 mg/kg morphine or saline (s.c.) twice daily for 5.5 days. At baseline and at 8, 24, 32, and 48 h following the final injection, latency to respond on a hot plate was determined across a range of temperatures (50, 52, 54, and 56 °C). Latency to respond decreased as a function of temperature. Response latencies during the withdrawal period were decreased in mice without wheel access treated with both 30 and 56 mg/kg of morphine. This increase in thermal sensitivity was significantly attenuated in singly housed mice with wheel access and in group-housed mice; however, the effects were less pronounced in the group-housed mice and depended upon the time during withdrawal. Both wheel access and group housing attenuate the increase in thermal sensitivity seen in morphine-treated mice during morphine withdrawal.

Water withdrawals, use, and trends in Florida, 2010

Marella, Richard L.

2014-01-01

In 2010, the total amount of water withdrawn in Florida was estimated to be 14,988 million gallons per day (Mgal/d). Saline water accounted for 8,589 Mgal/d (57 percent) and freshwater accounted for 6,399 Mgal/d (43 percent). Groundwater accounted for 4,166 Mgal/d (65 percent) of freshwater withdrawals, and surface water accounted for the remaining 2,233 Mgal/d (35 percent). Surface water accounted for nearly all (99.9 percent) saline-water withdrawals. An additional 659 Mgal/d of reclaimed wastewater was used in Florida during 2010. Freshwater withdrawals were greatest in Palm Beach County (707 Mgal/d), and saline-water withdrawals were greatest in Hillsborough County (1,715 Mgal/d). Fresh groundwater provided drinking water (public supplied and self-supplied) for 17.33 million people (92 percent of Florida’s population), and fresh surface water provided drinking water for 1.47 million people (8 percent). The statewide public-supply gross per capita use for 2010 was 134 gallons per day, whereas the statewide public-supply domestic per capita use was 85 gallons per day. The majority of groundwater withdrawals (almost 62 percent) in 2010 were obtained from the Floridan aquifer system, which is present throughout most of the State. The majority of fresh surface-water withdrawals (56 percent) came from the southern Florida hydrologic unit subregion and is associated with Lake Okeechobee and the canals in the Everglades Agricultural Area of Glades, Hendry, and Palm Beach Counties, as well as the Caloosahatchee River and its tributaries in the agricultural areas of Collier, Glades, Hendry, and Lee Counties. Overall, agricultural irrigation accounted for 40 percent of the total freshwater withdrawals (ground and surface), followed by public supply with 35 percent. Public supply accounted for 48 percent of groundwater withdrawals, followed by agricultural self-supplied (34 percent), commercial-industrial-mining self-supplied (7 percent), recreational

A lack of association between severity of nicotine withdrawal and individual differences in compensatory nicotine self-administration in rats

Rationale Compensatory smoking may represent an adverse consequence of smoking reduction or the use of reduced nicotine tobacco products. Factors contributing to individual variability in compensation are poorly understood. Objective To examine whether severity of nicotine withdrawal as measured by elevated intracranial self-stimulation (ICSS) thresholds is related to individual differences in compensatory nicotine self-administration (NSA) following unit dose reduction. Methods Rats were trained for ICSS and NSA (0.06 mg/kg/inf). After stabilization, effects of reducing the nicotine unit dose to 0.03 mg/kg/inf were examined. Following reacquisition of NSA (0.06 mg/kg/inf), effects of antagonist-precipitated withdrawal and saline extinction (spontaneous withdrawal) were examined. Results Reducing the NSA unit dose produced partial compensation as indicated by increased infusion rates but a 35% mean decrease in daily nicotine intake. Magnitude of compensation varied considerably among rats. Dose reduction did not elicit withdrawal in rats as a group, although there were substantial increases in ICSS thresholds in some animals. Intracranial self-stimulation thresholds were consistently elevated during precipitated and spontaneous withdrawal, confirming that rats were nicotine-dependent. Individual differences in compensation were not correlated with changes in ICSS thresholds during dose reduction, precipitated withdrawal, or spontaneous withdrawal. In a secondary analysis, greater precipitated withdrawal severity predicted greater initial nicotine-seeking during extinction. Conclusions Severity of nicotine withdrawal was not related to the degree of compensation in this protocol. These data do not support a role for nicotine withdrawal in individual differences in compensation during reduced nicotine exposure, but do suggest that withdrawal may contribute to nicotine-seeking during early abstinence.
