Ricinus communis L. is of great economic importance due to the oil extracted from its seeds. Castor oil has been used for pharmaceutical and industrial applications, as a lubricant or coating agent, as a component of plastic products, as a fungicide or in the synthesis of biodiesel fuels. After oil extraction, a castor cake with a large amount of protein is obtained. However, this by-product cannot be used as animal feed due to the presence of toxic (ricin) and allergenic (2S albumin) proteins. Here, we propose two processes for detoxification and allergen inactivation of the castor cake. In addition, we establish a biological test to detect ricin and validate these detoxification processes. In this test, Vero cells were treated with ricin, and cell death was assessed by cell counting and measurement of lactate dehydrogenase activity. The limit of detection of the Vero cell assay was 10 ng/mL using a concentration of 1.6 × 10 5 cells/well. Solid-state fermentation (SSF) and treatment with calcium compounds were used as cake detoxification processes. For SSF, Aspergillus niger was grown using a castor cake as a substrate, and this cake was analyzed after 24, 48, 72, and 96 h of SSF. Ricin was eliminated after 24 h of SSF treatment. The cake was treated with 4 or 8% Ca(OH) 2 or CaO, and both the toxicity and the allergenic properties were entirely abolished. A by-product free of toxicity and allergens was obtained

Relatively few cannabis dependent people seek treatment and little is known about determinants of treatment seeking. Treatment determinants were compared among 70 DSM-IV cannabis dependent patients and 241 non-treatment seeking DSM-IV cannabis dependent community subjects. In addition, perceived facilitators for treatment seeking were assessed in patients, whereas perceived barriers were assessed in 160/241 cannabis dependent community subjects not prepared to seek treatment (precluders), of whom 63/160 showed an objective treatment need, and 30/241 showed a subjective treatment need. Compared to non-treatment seekers, patients reported more cannabis use (176.9 versus 82.8 joints monthly), more symptoms of dependence (5.6 versus 4.5), higher perceived lack of social support (70.0% versus 41.1%), more pressure to seek treatment (58.6% versus 21.6%), a more positive attitude to treatment, and more previous treatments. In addition, patients reported more mental health problems (internalising disorders 57.1% versus 24.5%; externalising disorders 52.9% versus 35.3%) and more functional impairments (8.4 versus 4.8 monthly days out of role). Cannabis dependent 'precluders' reported desire for self-reliance (50.0%), preference for informal help (22.5%), and absent treatment need (16.9%) as their main reasons not to seek treatment, whereas cannabis dependent community subjects with a subjective treatment need mainly expressed desire for self-reliance (36.7%), treatment ineffectiveness (16.7%), and avoiding stigma (13.3%). Functional impairment, mental health problems and social pressure are important reasons to seek treatment in people with cannabis dependence. Treatment participation might improve if desire for self-reliance and the preference for informal help are considered, and perceived ineffectiveness of treatment and stigmatisation are publicly addressed.

However, there is limited information concerning clinical profiles of individuals seeking detoxification, and the opportunity to engage patients in detoxification for aftercare often is missed. This study examined clinical profiles of a geographically diverse sample of opioid-dependent adults in detoxification to discern the treatment needs of a growing number of women and whites with opioid addiction and to inform interventions aimed at improving use of aftercare or rehabilitation.Methods: The sample included 343 opioid-dependent patients enrolled in two national multisite studies of the National Drug Abuse Treatment Clinical Trials Network (CTN001-002. Patients were recruited from 12 addiction treatment programs across the nation. Gender and racial/ethnic differences in addiction severity, human immunodeficiency virus (HIV risk, and quality of life were examined.Results: Women and whites were more likely than men and African Americans to have greater psychiatric and family/social relationship problems and report poorer health-related quality of life and functioning. Whites and Hispanics exhibited higher levels of total HIV risk scores and risky injection drug use scores than African Americans, and Hispanics showed a higher level of unprotected sexual behaviors than whites.

Breaking the 'detox-loop' for alcoholics with social detoxification.

Science.gov (United States)

Richman, A; Neumann, B

1984-01-01

A significant number of alcoholics do not respond to detoxification as a step on the way to rehabilitation. Instead, they periodically 'dry out' and subsequently return to alcohol abuse. They do not accept the responsibilities inherent in the sick role (cooperation in order to improve status of health by entering and continuing treatment), although they do accept the privileges (care, shelter and asylum). Repeated detoxifications (within medical and non-medical settings) of persons who do not commit themselves to entering rehabilitation, are of minimum benefit to the patient and absorb resources which could be better used by those more amendable to treatment. An appropriate level of care--social detoxification--should be provided for ' detox - loopers '. Such a model can focus on the alcoholic's social welfare needs. Social detoxification provides both respite and basic care. The door to ongoing rehabilitation through professional services, as well as self-help groups, can remain open, without being the main objective of the centre.

Opportunities for the UK in solar detoxification

Christensen, P A; Walker, G M

1997-12-31

The most investigated approach to the solar detoxification of water involves the use of titanium dioxide, TiO{sub 2}, as the photocatalyst. The involvement of engineers in photocatalytic water detoxification research has been far too low, the research effort in photochemical reactor design has not been sufficient, with the result that a well-defined application for solar, or UV lamp, -driven TiO{sub 2}-based water detoxification technology has not been identified. The most effective and carefully investigated reactor design remains that in which TiO{sub 2} is added as a slurry to the contaminated water, however, the cost implications of the subsequent separation of the slurry from the treated water have not been addressed in any sensible fashion. The poor quantum efficiencies, rate constants and overlap between the solar emission spectrum and the absorption spectrum of TiO{sub 2} has resulted in very low solar detoxification efficiencies. This, in turn, means that very large areas of land will be necessary to accommodate a solar detoxification reactor, however UK industry, and the water companies in particular, have no interest in investing in water and/or wastewater treatment methods which demand increased land usage. In addition both industry and the water companies have little or no knowledge of, or interest in, novel detoxification technologies. From the above, the only conclusion can be that the application of the solar-driven photocatalytic detoxification of high-volume and most low-volume water in the UK is not a commercial option, and so is unlikely to be in the near future.

Full Text Available Textile effluents are among the most difficult-to-treat wastewaters, due to their considerable amount of recalcitrant and toxic substances. Fungal biosorption is viewed as a valuable additional treatment for removing pollutants from textile wastewaters. In this study the efficiency of Cunninghamella elegans biomass in terms of contaminants, COD and toxicity reduction was tested against textile effluents sampled in different points of wastewater treatment plants. The results showed that C. elegans is a promising candidate for the decolourisation and detoxification of textile wastewaters and its versatility makes it very competitive compared with conventional sorbents adopted in industrial processes.

Full Text Available Objective. To comparatively analyze the efficiency of methods for extracorporeal detoxification (ED of the body in abdominal sepsis (AS and to choose the optimum detoxifying methods in relation to the level of endotoxicosis.Material and methods. 56 patients (41 males and 15 females; mean age 39.4±12.2 years with surgical abdominal infection of various genesis, complicated by the development of sepsis whose treatment included ED methods, were examined. The level of intoxication and the efficiency of detoxification were evaluated by general clinical and biochemical blood parameters, the leukocytic intoxication index, the levels of low and medium molecular-weight substances in the body’s media. Hemosorption, plasmapheresis, hemodialysis, hemodiafiltration, and hemofiltration were used for detoxification.Results. Surgical abdominal infection is accompanied by endotoxemia that has no clear nosological specificity, but it depends on the pattern of a clinical course of the disease and is most pronounced in the septic syndrome. In AS, 80.4% of the patients are observed to have an irreversible decompensation phase and a terminal degree of endotoxicosis, which require detoxification. The use of different ED methods according to the level of intoxication may reduce the level of endotoxicosis and yield a persistent beneficial effect in 85.2% of cases of its application. Conclusion. Filtration and dialysis techniques (hemodialysis, hemofiltration, and hemodiafiltration are the methods of choice in AS. Hemosorption and plasmapheresis may be recommended for use at the early stages of endotoxicosis development and in preserved renal excretory function.

This study examined types of internal and external motivation for seeking treatment and the predictive utility of different types of motivation among 180 women with an alcohol use disorder (AUD) participating in a two-armed trial testing different individual and couple therapies for AUDs. Reasons for seeking treatment were coded for type of internal or external motivation. Most women (97%) cited internal reasons for seeking help, including: concern about progression of AUD (61.1%), health (43.3%), mental health (38.9%), and family (38.3%). Occupational concerns, an internal motivator cited by 6% of women, were associated with better drinking outcomes; interpersonal-family concerns were associated with poorer outcomes. Some motivators for seeking treatment may not be related to sustained changes in drinking, suggesting that understanding motivators for treatment may be inadequate to maintain change. Reasons for help-seeking may need to be addressed in treatment to produce long-lasting change. PMID:23501141

Alcohol and drug abusers' reasons for seeking treatment.

1994-01-01

Clients at two different treatment facilities were asked at assessment how influential each of 10 possible reasons were in their decision to change their alcohol or drug use. Clients at both facilities most often endorsed "weighing the pros and cons of drinking or drug use" and a "warning from spouse." Client's reasons for seeking treatment were also examined in relation to treatment compliance. Three reasons--"weighing the pros and cons," "hitting rock bottom," and experiencing a "major lifestyle change"--were predictive of treatment compliance. Clients who rated any of these reasons as influential were more likely to enter and complete treatment. Although more research is needed, knowledge of clients' reasons for seeking treatment might be useful in treatment matching.

Pollutant exposure at wastewater treatment works affects the detoxification organs of an urban adapter, the Banana Bat

The Banana Bat, Neoromicia nana, exploits pollution-tolerant chironomids at wastewater treatment works (WWTWs). We investigated how pollutant exposure impacts the detoxification organs, namely the liver and kidney of N. nana. (i) We performed SEM-EDS to quantify metal content and mineral nutrients, and found significant differences in essential metal (Fe and Zn) content in the liver, and significant differences in Cu and one mineral nutrient (K) in the kidneys. (ii) We performed histological analysis and found more histopathological lesions in detoxification organs of WWTW bats. (iii) We calculated hepatosomatic/renalsomatic indices (HSI/RSI) to investigate whole organ effects, and found significant increases in organ size at WWTWs. (iv) We quantified metallothionein 1E (MT1E), using Western Blot immunodetection. Contrary to predictions, we found no significant upregulation of MT1E in bats at WWTWs. Ultimately, N. nana exploiting WWTWs may suffer chronic health problems from sub-lethal damage to organs responsible for detoxifying pollutants. - Highlights: • We measured pollutant exposure effects on detoxification organs in bats. • Iron, zinc, copper and potassium levels were altered in pollutant-exposed bats. • There was no significant upregulation of metallothionein in liver or kidney. • Pollutant-exposed bats had increased organ indices and histopathological lesions. • These organ effects suggest health risks and increased mortality in the long-term. - Wastewater treatment plants provide a short-term benefit of abundant pollution-tolerant prey, but cause long-term physiological damage to the liver and kidneys in urban bats.

The Effect of Significant International Sports Events on Qualified Detoxification Treatment Outcome - Do Drop-Out Rates Change during UEFA European Championship?

Directory of Open Access Journals (Sweden)

Yvonne Sofin

Full Text Available No previous studies have evaluated the influence of significant international sports events on qualified detoxification treatment outcome. This prospective study examines the impact of the 2012 UEFA European Football Championship on inpatient treatment outcome of alcohol dependent patients. Hospital admission and premature drop-out rates of consecutively admitted alcohol dependent patients were determined before, during and immediately after the UEFA Championship in the year 2012. The admission rate of male patients increased significantly after the European Football Championship had ended whereas for female patients, no change in admission rate was found. Daily average discharge rate was calculated. No statistically relevant differences between the treatment days before, during and after the UEFA Championship was found for the discharges. During the tournament, exclusively male patients dropped out. Our results are consistent with an interpretation of an association between European Football Championship and detoxification treatment outcome. Further research to replicate and extend our findings is necessary.

Mycotoxins are fungal metabolites commonly occurring in food, which pose a health risk to the consumer. Maximum levels for major mycotoxins allowed in food have been established worldwide. Good agricultural practices, plant disease management, and adequate storage conditions limit mycotoxin levels in the food chain yet do not eliminate mycotoxins completely. Food processing can further reduce mycotoxin levels by physical removal and decontamination by chemical or enzymatic transformation of mycotoxins into less toxic products. Physical removal of mycotoxins is very efficient: manual sorting of grains, nuts, and fruits by farmers as well as automatic sorting by the industry significantly lowers the mean mycotoxin content. Further processing such as milling, steeping, and extrusion can also reduce mycotoxin content. Mycotoxins can be detoxified chemically by reacting with food components and technical aids; these reactions are facilitated by high temperature and alkaline or acidic conditions. Detoxification of mycotoxins can also be achieved enzymatically. Some enzymes able to transform mycotoxins naturally occur in food commodities or are produced during fermentation but more efficient detoxification can be achieved by deliberate introduction of purified enzymes. We recommend integrating evaluation of processing technologies for their impact on mycotoxins into risk management. Processing steps proven to mitigate mycotoxin contamination should be used whenever necessary. Development of detoxification technologies for high-risk commodities should be a priority for research. While physical techniques currently offer the most efficient post-harvest reduction of mycotoxin content in food, biotechnology possesses the largest potential for future developments.

Factors associated with attitudes toward seeking mental health treatment postpartum.

Attitudes toward seeking mental health treatment are a major predictor of seeking such treatment. Rates of seeking mental health treatment for postpartum depression are low despite contacts with health-care providers and available treatment. This study examined factors associated with four dimensions of attitude toward seeking mental health treatment among Israeli women in the postpartum period. Women (N = 1,059) were recruited (June 2008-February 2009) from a medical center's maternity department within the first two days following delivery and completed a sociodemographic survey and the Attitudes Toward Seeking Professional Psychological Help Scale. Low recognition of need for mental health treatment was associated with having a below average income and no personal and family depression history; low stigma tolerance was associated with being younger, having more children, and defining oneself as ultra-orthodox; low interpersonal openness was associated with having a below average income. Moreover, low confidence in mental health practitioners was associated with being younger and non-ultra-orthodox. Understanding which women are likely to score low on various dimensions of attitude can help target interventions for improving these factors, reducing barriers to receiving mental health treatment among specific groups of women. Research should continue to explore specific attitude dimensions among various populations.

To examine whether and how stigma influences attitudes towards seeking treatment for urinary incontinence, and whether its effect varies by symptom severity. Urinary incontinence is prevalent among women, but few seek treatment. Negative attitudes towards urinary incontinence treatment inhibit from seeking care. Urinary incontinence is a stigmatised attribute. However, the relationship between stigma and attitudes towards seeking treatment for urinary incontinence has not been well understood. This was a cross-sectional community-based study. We enrolled a sample of 305 women aged 40-65 years with stress urinary incontinence from three communities in a Chinese city between May-October in 2011. Data were collected on socio-demographic characteristics, urinary incontinence symptoms, stigma and attitudes towards seeking treatment for urinary incontinence using a self-reported questionnaire. Effects of stigma were analysed using path analysis. Attitudes towards seeking treatment for urinary incontinence were generally negative. For the total sample, all the stigma domains of social rejection, social isolation and internalised shame had direct negative effects on treatment-seeking attitudes. The public stigma domain of social rejection also indirectly affected treatment-seeking attitudes through increasing social isolation, as well as through increasing social isolation and then internalised shame. The final model accounted for 28% of the variance of treatment-seeking attitudes. Symptom severity influenced the strength of paths: the effect of internalised shame was higher in women with more severe urinary incontinence. Stigma enhances the formation of negative attitudes towards seeking treatment for urinary incontinence; public stigma affects treatment-seeking attitudes through internalisation of social messages. Stigma reduction may help incontinent women to form positive treatment-seeking attitudes and engage them in treatment. Interventions should specifically target

2010-10-01

Full Text Available Abstract Background Malaria places a significant burden on the limited resources of many low income countries. Knowing more about why and where people seek treatment will enable policy makers to better allocate the limited resources. This study aims to better understand what influences treatment-seeking behaviour for malaria in one such low-income country context, Papua New Guinea (PNG. Methods Two culturally, linguistically and demographically different regions in PNG were selected as study sites. A cross sectional household survey was undertaken in both sites resulting in the collection of data on 928 individuals who reported suffering from malaria in the previous four weeks. A probit model was then used to identify the factors determining whether or not people sought treatment for presumptive malaria. Multinomial logit models also assisted in identifying the factors that determined where people sought treatments. Results Results in this study build upon findings from other studies. For example, while distance in PNG has previously been seen as the primary factor in influencing whether any sort of treatment will be sought, in this study cultural influences and whether it was the first, second or even third treatment for a particular episode of malaria were also important. In addition, although formal health care facilities were the most popular treatment sources, it was also found that traditional healers were a common choice. In turn, the reasons why participants chose a particular type of treatment differed according to the whether they were seeking an initial or subsequent treatments. Conclusions Simply bringing health services closer to where people live may not always result in a greater use of formal health care facilities. Policy makers in PNG need to consider within-country variation in treatment-seeking behaviour, the important role of traditional healers and also ensure that the community fully understands the potential implications

Gamma-hydroxybutyrate (GHB) detoxification procedures have been insufficiently studied for effectiveness and safety. Based on case reports, benzodiazepines are generally regarded as first-choice agents in GHB detoxification. Detoxification by titration and tapering (DeTiTap) with pharmaceutical GHB in an open-label consecutive case series of 23 GHB-dependent patients showed to be feasible, effective and safe. This study further explored the feasibility, effectiveness and safety of this detoxification procedure in a large group of patients. A large observational multicenter study was carried out in six addiction treatment centers in the Netherlands. GHB-dependent inpatients (229 unique patients, 274 admissions) were titrated on and tapered off with pharmaceutical GHB. Successful detoxification was achieved in 85% of cases. Detoxification was carried out in 12.5days in most patients. The DeTiTap procedure proved to be feasible and significantly reduced the experienced withdrawal symptoms and craving (p≤0.001). Several symptoms were found to influence the course of subjective withdrawal symptoms. During detoxification, psychological symptoms such as depression, anxiety, and stress decreased (p≤0.05). The main complications were hypertension and anxiety. Six patients were sent to the general hospital for observation, but all six were able to continue detoxification in the addiction treatment centers. Most patients (69%) relapsed within three months after detoxification. The DeTiTap procedure using pharmaceutical GHB seems a safe alternative to benzodiazepines as a GHB detoxification procedure. However, the high relapse rates warrant further investigation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Effects of lyric analysis interventions on treatment motivation in patients on a detoxification unit: a randomized effectiveness study.

Silverman, Michael J

2015-01-01

Treatment motivation is a key component in the early rehabilitative stages for people with substance use disorders. To date, no music therapy researcher has studied how lyric analysis interventions might affect motivation in a randomized controlled design. The primary purpose of this study was to determine the effect of lyric analysis interventions on treatment motivation in patients on a detoxification unit using a single-session wait-list control design. A secondary purpose was to determine if there were between-group differences concerning two contrasting songs used for the lyric analyses. Participants (N=104) were cluster randomized to a group lyric analysis condition or a wait-list control condition. Participants received either a "Hurt" or a "How to Save a Life" lyric analysis treatment. The Texas Christian University Treatment Motivation Scale-Client Evaluation of Self at Intake (CESI) (Simpson, 2008[2005]) was used to measure aspects of treatment motivation: problem recognition, desire for help, treatment readiness, pressures for treatment, and total motivation. Results indicated significant between-group differences in measures of problem recognition, desire for help, treatment readiness, and total motivation, with experimental participants having higher treatment motivation means than control participants. There was no difference between the two lyric analysis interventions. Although the song used for lyric analysis interventions did not affect outcome, a single group-based music therapy lyric analysis session can be an effective psychosocial treatment intervention to enhance treatment motivation in patients on a detoxification unit. Limitations, implications for clinical practice, and suggestions for future research are provided. © the American Music Therapy Association 2015. All rights reserved.

Full Text Available Opioid use disorders present with distressing withdrawal symptoms at the time of detoxification. The pharmacological agents and methods currently in use for detoxification mainly include buprenorphine, methadone, and clonidine. Many other pharmacological agents have been tried for opioid detoxification. This review takes a look at the newer pharmacological options, both opioid agonists and non-agonist medications that have been utilized for detoxification. Peer reviewed articles were identified using PubMed and PsychInfo databases. The keywords included for the search were a combination of ′opioid′ and ′detoxification′ and their synonyms. All the articles published in the last 10 years were screened for. Relevant data was extracted from identified studies. Many newer pharmacological agents have been tried in detoxification of opioids. However, the quest for a safe, efficacious, cost-effective pharmacological option which requires minimal monitoring still continues. The role of non-pharmacological measures and alternative medicine needs further evaluation.

Background and aims This study examined the prevalence of, and factors associated with, men's interest in seeking treatment for use of pornography. Methods Using an Internet-based data-collection procedure, we recruited 1,298 male pornography users to complete questionnaires assessing demographic and sexual behaviors, hypersexuality, pornography-use characteristics, and current interest in seeking treatment for use of pornography. Results Approximately 14% of men reported an interest in seeking treatment for use of pornography, whereas only 6.4% of men had previously sought treatment for use of pornography. Treatment-interested men were 9.5 times more likely to report clinically significant levels of hypersexuality compared with treatment-disinterested men (OR = 9.52, 95% CI = 6.72-13.49). Bivariate analyses indicated that interest-in-seeking-treatment status was associated with being single/unmarried, viewing more pornography per week, engaging in more solitary masturbation in the past month, having had less dyadic oral sex in the past month, reporting a history of seeking treatment for use of pornography, and having had more past attempts to either "cut back" or quit using pornography completely. Results from a binary logistic regression analysis indicated that more frequent cut back/quit attempts with pornography and scores on the Hypersexual Behavior Inventory - Control subscale were significant predictors of interest-in-seeking-treatment status. Discussion and conclusions Study findings could be used to inform current screening practices aimed at identifying specific aspects of sexual self-control, impulsivity, and/or compulsivity associated with problematic use of pornography among treatment-seeking individuals.

Full Text Available Current research highlights the use of aquatic macrophyte Equisetum diffusum (Himalayan horsetail for lead detoxification. This plant species can grow in waste cathode ray tube (CRT powder and absorbs its Pb. X-ray fluorescence spectroscopy (XRF analysis of plant ash shows that 68 mg/kg lead concentration in the untreated plant was improved to 7600 mg/kg in CRT powder after 90 days. The role of monosilicic and/or monoplumbic acid as reaction intermediates for Pb detoxification and associated bioaccumulation is proposed. Pb detoxification in E. diffusum is mainly rendering around the iso-electronic nature of Pb and Si and forms similar phytochelatin (PC complexes with available family of peptide ligands. The study focuses on the underlying functions of silicon containing plants in metal detoxification.

Barriers to treatment for older adults seeking psychological therapy.

Wuthrich, Viviana M; Frei, Jacqueline

2015-07-01

Older adults with mental health disorders underutilize mental health services more than other adults. While there are well known general barriers to help seeking across the population, specific barriers for older adults include difficulties with transportation, beliefs that it is normal to be anxious and depressed in old age, and beliefs by referrers that psychological therapy is less likely to be effective. This study examined barriers related to identifying the need for help, seeking help and participating in therapy in a clinical population of older adults. Sixty older adults (aged 60-79 years) with comorbid anxiety and unipolar mood disorders completed barriers to treatment questionnaires before and after psychological group treatment, as well as measures of cognitive ability, anxiety, depression, and quality of life at baseline. The greatest barriers to help seeking related to difficulties identifying the need for help, with 50% of the sample reporting their belief that their symptoms were normal as a major barrier. Other major barriers identified were related to: self-reliance, cost of treatment, and fear of medication replicating previous findings. The main barriers reported for difficulties in continuing therapy included not finding therapy helpful, cost of treatment, and thinking that the therapist did not understand their issues. The main barriers identified related to issues with identifying the need to seek help. More attention is needed to educate older adults and professionals about the need for, and effectiveness of, psychological therapies for older adults with anxiety and depression to reduce this barrier to help seeking.

Full Text Available Abstract Background Obese and overweight people have a higher risk of both chronic physical illness and mental illness. Obesity is reported to be positively associated with psychiatric disorders, especially in people who seek obesity treatment. At the same time, obesity treatment may be influenced by psychological factors or personality characteristics. This study aimed to understand the prevalence of mental disorders among ethnic Chinese who sought obesity treatment. Methods Subjects were retrospectively recruited from an obesity treatment center in Taiwan. The obesity treatments included bariatric surgery and non-surgery treatment. All subjects underwent a standardized clinical evaluation with two questionnaires and a psychiatric referral when needed. The psychiatric diagnosis was made thorough psychiatric clinic interviews using the SCID. A total of 841 patients were recruited. We compared the difference in psychiatric disorder prevalence between patients with surgical and non-surgical treatment. Results Of the 841 patients, 42% had at least one psychiatric disorder. Mood disorders, anxiety disorders and eating disorders were the most prevalent categories of psychiatric disorders. Females had more mood disorders and eating disorders than males. The surgical group had more binge-eating disorder, adjustment disorder, and sleep disorders than the non-surgical group. Conclusion A high prevalence of psychiatric disorders was found among ethnic Chinese seeking obesity treatment. This is consistent with study results in the US and Europe.

Reas, Deborah L; Masheb, Robin M; Grilo, Carlos M

2004-05-01

This study examined reasons for seeking treatment reported by obese patients diagnosed with binge eating disorder (BED). Participants were 248 adults (58 men and 190 women) who met DSM criteria for BED. Participants were recruited through advertisements for treatment studies looking for persons who wanted to "stop binge eating and lose weight." Patients' reasons for seeking treatment were examined with respect to demography (gender and age), obesity (BMI and age of onset), features of eating disorders, and associated psychological functioning (depression and self-esteem). Of the 248 participants, 64% reported health concerns and 36% reported appearance concerns as their primary reason for seeking treatment. Reasons for seeking treatment did not differ significantly by gender. Patients seeking treatment because of appearance-related reasons had lower BMIs than those reporting health-related reasons (34.8 vs. 38.5, respectively), but they reported greater body dissatisfaction, more features of eating disorders, and lower self-esteem. Reasons that prompt treatment seeking among obese individuals with BED reflect meaningful patient characteristics and, therefore, warrant assessment and consideration during treatment planning. Further research is needed to determine whether reasons for treatment seeking among different obese patient groups affect treatment outcomes. Copyright 2004 NAASO

Stigma associated with PTSD: perceptions of treatment seeking combat veterans.

2013-06-01

Although stigma associated with serious mental illness, substance abuse disorders, and depression has been studied very little is known about stigma associated with Posttraumatic Stress Disorder (PTSD). This study explored stigma related to PTSD among treatment-seeking Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) combat veterans. Sixteen treatment-seeking OEF/OIF veterans with combat-related PTSD participated in focus groups. We used qualitative methods to explore PTSD-related stigma. Common perceived stereotypes of treatment-seeking veterans with PTSD included labels such as "dangerous/violent," or "crazy," and a belief that combat veterans are responsible for having PTSD. Most participants reported avoiding treatment early on to circumvent a label of mental illness. Participants initially reported experiencing some degree of self-stigma; however, following engagement in treatment they predominantly resisted these stereotypes. Although most participants considered combat-related PTSD as less stigmatizing than other mental illnesses, they reported difficulties with reintegration. Such challenges likely stem from both PTSD symptoms and veterans' perceptions of how the public views them. Most reported that fellow combat veterans best understood them. Awareness of public stereotypes impacts help seeking at least early in the course of illness. Peer-based outreach and therapy groups may help veterans engage in treatment early and resist stigma.

Mixed Waste Treatment Using the ChemChar Thermolytic Detoxification Technique

International Nuclear Information System (INIS)

Kuchynka, D.J.

1997-01-01

This R and D program addresses the treatment of mixed waste employing the ChemChar Thermolytic Detoxification process. Surrogate mixed waste streams will be treated in a four inch diameter, continuous feed, adiabatic reactor with the goal of meeting all regulatory treatment levels for the contaminants in the surrogates with the concomitant production of contaminant free by-products. Successful completion of this program will show that organic contaminants in mixed waste surrogates will be converted to a clean, energy rich synthesis gas capable of being used, without further processing, for power or heat generation. The inorganic components in the surrogates will be found to be adsorbed on a macroporous coal char activated carbon substrate which is mixed with the waste prior to treatment. These contaminants include radioactive metal surrogate species, RCRA hazardous metals and any acid gases formed during the treatment process. The program has three main tasks that will be performed to meet the above objectives. The first task is the design and construction of the four inch reactor at Mirage Systems in Sunnyvale, CA. The second task is production and procurement of the activated carbon char employed in the ChemChartest runs and identification of two surrogate mixed wastes. The last task is testing and operation of the reactor on char/surrogate waste mixtures to be performed at the University of Missouri. The deliverables for the project are a Design Review Report, Operational Test Plan, Topical Report and Final Report. This report contains only the results of the design and construction carbon production-surrogate waste identification tasks.Treatment of the surrogate mixed wastes has just begun and will not be reported in this version of the Final Report. The latter will be reported in the final version of the Final Report

Mixed waste treatment using the ChemChar thermolytic detoxification technique

Energy Technology Data Exchange (ETDEWEB)

Kuchynka, D.

1995-12-31

The diversity of mixed waste matrices contained at Department of Energy sites that require treatment preclude a single, universal treatment technology capable of handling sludges, solids, heterogeneous debris, aqueous and organic liquids and soils. Versatility of the treatment technology, volume reduction and containment of the radioactive component of the mixed waste streams are three criteria to be considered when evaluating potential treatment technologies. The ChemChar thermolytic detoxification process being developed under this R and D contract is a thermal, chemically reductive technology that converts the organic portion of a mixed waste stream to an energy-rich synthesis gas while simultaneously absorbing volatile inorganic species (metals and acid gases) on a macroporous, carbon-based char. The latter is mixed with the waste stream prior to entering the reactor. Substoichiometric amounts of oxidant are fed into the top portion of the cylindrical reactor generating a thin, radial thermochemical reaction zone. This zone generates all the necessary heat to promote the highly endothermic reduction of the organic components in the waste in the lower portion of the reactor, producing, principally, hydrogen and carbon monoxide. The solid by-product is a regenerated carbon char that, depending on the inorganic loading, is capable for reuse. The in situ scrubbing of contaminants by the char within the reactor coupled with a char filter for final polishing produce an exceptionally clean synthesis gas effluent suitable for on-site generation of heat, steam or electricity. Despite the elevated temperatures in the thermochemical reaction zone, the reductive nature of the process precludes formation of nitrogen oxides and halogenated organic compound by-products.

Full Text Available Ultra rapid opioid detoxification (UROD is one of the new methods of detoxification. This method of detoxification involves putting patients under general anesthesia and actively giving them opioid antagonists. The objective of this study was to evaluate effects of anesthesia duration in UROD on severity of withdrawal syndrome. Sixty addicted patients seeking UROD procedure assigned randomly to one of the 2hr, 4hr or 6hr anesthesia duration groups. Premedication and anesthesia procedure (induction and maintenance were the same for three groups. Detoxification was done for all patients with 50 mg oral naltroxane (prior to induction and 20 mg intravenous naloxane (8 mg/bolus and 12 mg/infusion. Blood pressure, heart rate and respiratory rate were automatically measured and recorded every 5 minutes. The severity of withdrawal syndrome was measured and recorded every one hour during anesthesia, 2hours post-anesthesia, and 12 and 24 hours following the induction of anesthesia according to the Wang Scale modified by Lomier (WSMBL. Patients aged 20-58 in three groups. Three cases experienced delirium after detoxification that lasted 24 hours in one. Severity of withdrawal syndrome in patients of groups 2, 4 and 6 hour were 8.7, 7.4 and 5.1 respectively during anesthesia and 12.3, 11.1 and 13.9 after 18 hours of anesthesia. Results of this study showed that, in standard settings, UROD is a safe method for detoxification and has low complications. The withdrawal symptoms during and after anesthesia are low. Shortening the duration of anesthesia has no affect on severity of withdrawal syndrome during and after anesthesia.

Readmissions are among the most problematic and expensive problems in the treatment of substance use disorders. To evaluate the characteristics associated with four or more inpatient medically managed detoxification admissions in FY 2012, when all had post-discharge appointments within 7 days. A retrospective case control study. A total of 38 (6.0%) of 623 unique veterans had four or more detoxification admissions (high utilizers). A random sample of 42 was selected from the remaining 585 people (comparison group). In all, 264 detoxification and 70 hospital admissions for other reasons were reviewed. The high utilizers had more alcohol use disorder (AUD, 82% versus 59%, p = 0.03) of significantly longer duration (mean 28.9 years [SD = 17] vs. 19.6 [SD = 13.4], p = 0.01). AUD increased the odds of being a high utilizer three-fold [OR = 3.0, 95% CI 1.1, 8.4], and every additional year of AUD, increased the number of admissions 1.3%, p = 0.0006. The high utilizers did not differ from the comparison group with regards to either number of hospitalizations for other reasons (mean 1.2 [SD = 1.9] vs. 0.57 [SD = 0.8], p = 0.06) or rate of 7 day post discharge appointments kept (46.9% vs. 49.3%, p = 0.82). High utilizers were a small percentage of patients (6.0%) who accounted for a disproportionate number (23%) of 977 detoxification admissions. They had greater disease severity as manifest by more years of AUD. They were not more likely to have hospitalizations for other reasons or less likely to keep post discharge appointments. These patients may warrant different services tailored to prevent hospital readmissions for detoxification.

Pesticide tolerance poses many challenges for pest control, particularly for destructive pests such as Bradysia odoriphaga. Imidacloprid has been used to control B. odoriphaga since 2013, however, imidacloprid resistance in B. odoriphaga has developed in recent years. Identifying actual and potential genes involved in detoxification metabolism of imidacloprid could offer solutions for controlling this insect. In this study, RNA-seq was used to explore differentially expressed genes in B. odoriphaga that respond to imidacloprid treatment. Differential expression data between imidacloprid treatment and the control revealed 281 transcripts (176 with annotations) showing upregulation and 394 transcripts (235 with annotations) showing downregulation. Among them, differential expression levels of seven P450 unigenes were associated with imidacloprid detoxification mechanism, with 4 unigenes that were upregulated and 3 unigenes that were downregulated. The qRT-PCR results of the seven differential expression P450 unigenes after imidacloprid treatment were consistent with RNA-Seq data. Furthermore, oral delivery mediated RNA interference of these four upregulated P450 unigenes followed by an insecticide bioassay significantly increased the mortality of imidacloprid-treated B. odoriphaga. This result indicated that the four upregulated P450s are involved in detoxification of imidacloprid. This study provides a genetic basis for further exploring P450 genes for imidacloprid detoxification in B. odoriphaga.

Full Text Available Quinclorac is a highly selective auxin-type herbicide, and is widely used in the effective control of barnyard grass in paddy rice fields, improving the world’s rice yield. The herbicide mode of action of quinclorac has been proposed and hormone interactions affect quinclorac signaling. Because of widespread use, quinclorac may be transported outside rice fields with the drainage waters, leading to soil and water pollution and environmental health problems.In this study, we used 57K Affymetrix rice whole-genome array to identify quinclorac signaling response genes to study the molecular mechanisms of action and detoxification of quinclorac in rice plants. Overall, 637 probe sets were identified with differential expression levels under either 6 or 24 h of quinclorac treatment. Auxin-related genes such as GH3 and OsIAAs responded to quinclorac treatment. Gene Ontology analysis showed that genes of detoxification-related family genes were significantly enriched, including cytochrome P450, GST, UGT, and ABC and drug transporter genes. Moreover, real-time RT-PCR analysis showed that top candidate P450 families such as CYP81, CYP709C and CYP72A genes were universally induced by different herbicides. Some Arabidopsis genes for the same P450 family were up-regulated under quinclorac treatment.We conduct rice whole-genome GeneChip analysis and the first global identification of quinclorac response genes. This work may provide potential markers for detoxification of quinclorac and biomonitors of environmental chemical pollution.

Previous investigations have identified individuals who meet criteria for Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) substance dependence as applied to caffeine, but there is little research on treatments for caffeine dependence. This study aimed to thoroughly characterize individuals who are seeking treatment for problematic caffeine use. Ninety-four individuals who identified as being psychologically or physically dependent on caffeine, or who had tried unsuccessfully to modify caffeine consumption participated in a face-to-face diagnostic clinical interview. They also completed measures concerning caffeine use and quitting history, reasons for seeking treatment, and standardized self-report measures of psychological functioning. Caffeine treatment seekers (mean age 41 years, 55% women) consumed an average of 548 mg caffeine per day. The primary source of caffeine was coffee for 50% of the sample and soft drinks for 37%. Eighty-eight percent reported prior serious attempts to modify caffeine use (mean 2.7 prior attempts), and 43% reported being advised by a medical professional to reduce or eliminate caffeine. Ninety-three percent met criteria for caffeine dependence when generic DSM-IV-TR substance dependence criteria were applied to caffeine use. The most commonly endorsed criteria were withdrawal (96%), persistent desire or unsuccessful efforts to control use (89%), and use despite knowledge of physical or psychological problems caused by caffeine (87%). The most common reasons for wanting to modify caffeine use were health-related (59%) and not wanting to be dependent on caffeine (35%). This investigation reveals that there are individuals with problematic caffeine use who are seeking treatment and suggests that there is a need for effective caffeine dependence treatments. 2013 APA, all rights reserved

Many college students may experience mental health problems but do not seek treatment from mental health professionals. The present study examined how perceived stigma and self-stigma toward seeking mental health treatment, as well as perceptions of self-reliance for coping with mental health problems, relate to college student treatment-seeking. In total, 246 students completed a self-report survey that included measures of perceived stigma and self-stigma for treatment-seeking, self-reliance for addressing mental health concerns, self-reported mental health problems, symptoms of depression and alcohol-related problems, attitudes toward treatment-seeking, and treatment-seeking behavior. Regression analyses revealed that higher perceived stigma, self-stigma, and self-reliance were all related to a more negative attitude toward treatment-seeking. In a 3-path mediation model, bootstrapping results indicated an indirect effect where perceived stigma was related to attitude toward treatment-seeking and treatment-seeking behaviors through self-stigma and self-reliance. Specifically, higher perceived stigma was related to higher self-stigma, higher self-stigma was related to higher self-reliance, and higher self-reliance was associated with a more negative attitude toward treatment-seeking in the overall sample, and a decreased probability of having sought treatment among those who screened positive for a mental health problem. Perceived stigma may influence whether or not college students seek treatment for mental health problems by potentially increasing stigmatizing attitudes toward themselves and increasing preferences for handling problems on their own. Researchers and practitioners are recommended to seek a better understanding of the complex treatment barriers to reduce stigma and facilitate treatment-seeking. (c) 2015 APA, all rights reserved).

Prior research has found higher rates of mental health problems among sexual minority individuals. We examine treatment-seeking for depression, as well as its relationship with sexual orientation, in a large, multilingual, international sample. Participants in an automated, quintilingual internet-based depression screening tool were screened for depression, and completed several background measures, including sexual orientation (with an option to decline to state) and past and current depression treatment seeking. 3695 participants screened positive for current or past depression and responded to the sexual orientation question. Those who declined to state their sexual orientation were far less likely to seek any treatment than individuals endorsing any orientation; they were especially unlikely to seek psychotherapy. Individuals identifying as bisexual sought both psychotherapy and alternative treatments at a higher rate than other groups. An interaction was observed between sexual orientation and gender, such that lesbian women were especially likely to have used psychotherapy. Other variables that emerged as significant predictors of treatment-seeking for depression included age and participant's language. Limitations include possible misinterpretation of translated terms due to regional differences, and possible limits to generalizability due to this study being conducted on the internet. Our results suggest that individuals who decline to state their sexual orientation may be more likely to forgo effective treatments for depression. Further studies of depression service utilization should focus on developing treatment modalities that could better engage sexual minority individuals, especially those who are reluctant to disclose their orientation.

Rhodes, Blythe E; Gottfredson, Nisha C; Hill, Lauren M

2018-04-01

Addiction rates are rising faster among women than men. However, women with substance use disorders are less likely to enter treatment than males. This study seeks to understand how turning-point events and other maturational processes affect "life course persistent" women's motivations for seeking treatment for their disorder. We conducted semi-structured in-depth interviews with 30 women who were receiving treatment for addiction using thematic analysis. Recurring themes were as follows: experiences of rock-bottom events prior to entering treatment, feeling "sick and tired" in regard to both their physical and mental health, and shifting identities or perceptions of themselves. We discuss the importance of motivating shifts in identity to prevent women from entering treatment as a result of more traumatic mechanisms as well as the possibility of intercepting women with substance dependence and chronic health conditions in primary care or hospital settings with the aim of encouraging treatment.

Limited data are available on the characteristics of adolescents with obesity who seek bariatric surgery. Existing data suggest that adolescent surgery candidates have a higher body mass index (BMI) than comparison adolescents with obesity, but the limited findings regarding psychosocial functioning are mixed. This study aimed to compare BMI and psychosocial functioning among adolescent bariatric surgery candidates, outpatient medical-treatment-seeking adolescents with obesity (receiving lifestyle modification), and adolescents in the normal-weight range. All adolescents completed self-report measures of impulsivity, delay discounting, depression, anxiety, stress, eating pathology, family functioning and quality of life, and had their height and weight measured. Adolescent surgical candidates had higher BMIs than both comparison groups. Surgical candidates did not differ from medical-treatment-seeking adolescents with obesity on any measure of psychosocial functioning, but both groups of adolescents with obesity reported greater anxiety and eating pathology and poorer quality of life than normal-weight adolescents. Quality of life no longer differed across groups after controlling for BMI, suggesting that it is highly related to weight status. Adolescents with obesity may experience greater anxiety, eating pathology, and quality of life impairments than their peers in the normal-weight range regardless of whether they are seeking surgery or outpatient medical treatment. Clinical implications and directions for future research are discussed. © 2017 World Obesity Federation.

Leo, R J; Narendran, R; DeGuiseppe, B

2000-10-01

Tramadol hydrochloride is a centrally acting analgesic with a partial affinity for the opiate receptor (mu), having an analgesic potency estimated to be one tenth that of morphine. While preclinical investigations suggested that abuse liability associated with tramadol use is low, there are increasing numbers of cases reported to the U.S. Food and Drug Administration of abuse, dependence, and withdrawal associated with tramadol use. A case of a patient with tramadol dependence requiring detoxification with methadone is presented. Acute management of significant tramadol dependence has not yet been reported in the literature. Long-term treatment issues are also discussed.

The treatment, storage, and disposal of hazardous and mixed wastes incur significant costs for Department of Energy (DOE) installations. These wastes must be managed under strict environmental controls and regulations to prevent the possibility of migration of hazardous materials to the biosphere. Through the Hazardous Waste Remedial Actions Program, the DOE is seeking to develop innovative ways of improving current treatment technologies to eliminate the hazardous components of wastes, reduce waste management costs, and minimize the volume requiring disposal as hazardous or mixed waste. Sponsored projects progress from research and development to field demonstration. Among the innovative technologies under development are supercritical water oxidation of hazardous chemicals, microwave-assisted destruction of chlorinated hydrocarbons, paramagnetic separation of metals from waste, detoxification and reclamation of waste acid, nitrate destruction through calcination, treatment/disposal of reactive metals, and methodologies for encapsulation. Technologies at a demonstration phase include detoxification of mixed waste sludge, microbial degradation of polychlorinated biphenyls in soil, and the remediation process for a hydrocarbon spill. 14 refs

Why Irish women delay seeking treatment for urinary incontinence : a focus group study

OpenAIRE

Ni Aileasa, Mairead

2011-01-01

non-peer-reviewed Background: Urinary Incontinence is defined as "any involuntary leakage of urine" (Abrams et al, 2002). Living with incontinence can effect one's life greatly. Many women delay seeking treatment and often do not seek any help (Dolan et al, 1999), despite physiotherapy being an effective treatment (Neumann et al, 2005). Therefore, there is a need to discover why women delay seeking help, such as physiotherapy and continue to live with incontinence. Objectives: To establ...

Longitudinal associations between social phobia (SP), depression and eating disorders (EDs), and the impact of antecedent SP and depression on subsequent treatment seeking for EDs have rarely been explored in prospective adolescent population studies. We aimed to examine these associations in a large-scale follow-up study among middle adolescents. We surveyed 3278 Finnish adolescents with a mean age of 15 years for these disorders. Two years later, 2070 were reached and again surveyed for psychopathology and treatment seeking. Longitudinal associations between the self-reported disorders and treatment-seeking patterns for self-acknowledged ED symptoms were examined in multivariate analyses, controlling for SP/depression comorbidity and relevant socioeconomic covariates. Self-reported anorexia nervosa (AN) at age 15 years predicted self-reported depression at age 17 years. Furthermore, self-reported SP at age 15 years predicted not seeking treatment for bulimia nervosa (BN) symptoms, while self-reported depression at age 15 years predicted not seeking treatment for AN symptoms during the follow-up period. Adolescents with AN should be monitored for subsequent depression. Barriers caused by SP to help seeking for BN, and by depression for AN, should be acknowledged by healthcare professionals who encounter socially anxious and depressive adolescents, especially when they present with eating problems.

To analyse the association between perceived discrimination and refraining from seeking required medical treatment and the contribution of socioeconomic disadvantage. Data from the Swedish National Survey of Public Health 2004 were used for analysis. Respondents were asked whether they had refrained from seeking required medical treatment during the past 3 months. Perceived discrimination was based on whether respondents reported that they had been treated in a way that made them feel humiliated (due to ethnicity/race, religion, gender, sexual orientation, age or disability). The Socioeconomic Disadvantage Index (SDI) was developed to measure economic deprivation (social welfare beneficiary, being unemployed, financial crisis and lack of cash reserves). Swedish population-based survey of 14,736 men and 17,115 women. Both perceived discrimination and socioeconomic disadvantage were independently associated with refraining from seeking medical treatment. Experiences of frequent discrimination even without any socioeconomic disadvantage were associated with three to nine-fold increased odds for refraining from seeking medical treatment. A combination of both frequent discrimination and severe SDI was associated with a multiplicative effect on refraining from seeking medical treatment, but this effect was statistically more conclusive among women (OR = 11.6, 95% CI 8.1 to 16.6; Synergy Index (SI) = 2.0 (95% CI 1.2 to 3.2)) than among men (OR = 12, 95% CI 7.7 to 18.7; SI = 1.6 (95% CI 1.3 to 2.1)). The goal of equitable access to healthcare services cannot be achieved without public health strategies that confront and tackle discrimination in society and specifically in the healthcare setting.

Although completion of detoxification (detox) and a successful transition from detox to substance use disorder (SUD) treatment and/or mutual-help groups are associated with better SUD outcomes, many patients do not complete detox or do not receive SUD care following detox. The purpose of this structured evidence review, summarizing data extraction on a yield of 26 articles, is to identify patient, program, and system factors associated with the outcomes of completion of alcohol detox and successful transitions from alcohol detox to SUD treatment and mutual-help group participation. The review found wide variability among studies in the rates at which patients complete a detox episode (45 to 95%) and enter SUD treatment or mutual-help groups after detox (14 to 92%). Within program factors, behavioral practices that contribute to both detox completion and transitioning to SUD care after detox entail involving the patient's family and utilizing motivational-based approaches. Such practices should be targeted at younger patients, who are less likely to complete detox. Although more studies using a randomized controlled trial design are needed, the evidence suggests that barriers to detox completion and transition to SUD care can be overcome to improve patient outcomes.

To determine household factors associated with treatment seeking for malaria. The study was carried out in four districts of Madhya Pradesh with different malaria endemicity. A total of 1470 households were interviewed in which at least one member suffered from microscopically confirmed malaria in the 3 months preceding the survey. Socio-demographic, economic, cultural characteristics, their health beliefs, knowledge and practices regarding malaria and choice of treatment seeking were explored. A total of 764 households were from high-endemic and 706 from low-endemic areas. More than half of household heads were illiterate; most are farmers. Approximately 46% sought treatment for malaria from unqualified informal providers; 19% from qualified private health practitioners and 35% from government health providers. Analysis revealed that household's area of residence, education, occupation, ethnicity, use of preventive measures, economic status, knowledge and practices, distance and delayed treatment seeking was strongly associated with the type of healthcare providers selected. Demand for formal health services among the poor, illiterate, tribal population living in remote areas is low. Accessible and affordable health services and a sensitisation programme to increase the demand for formal providers are needed. © 2017 John Wiley & Sons Ltd.

The relation between trait mindfulness and aggression in men seeking residential substance use treatment.

Science.gov (United States)

Shorey, Ryan C; Anderson, Scott; Stuart, Gregory L

2015-06-01

There has been an abundance of research in recent years on mindfulness, including mindfulness within individuals seeking substance use treatment. However, to date, there has been no research on whether trait mindfulness is associated with increased aggression among individuals seeking substance use treatment. Past research has demonstrated that individuals in substance use treatment evidence higher levels of aggression than non-substance abusers, and preliminary research has shown that trait mindfulness is inversely associated with aggression in non-substance-use treatment-seeking populations. The current study examined whether trait mindfulness was associated with aggression among men seeking residential substance use treatment (N = 116). Results demonstrated that lower trait mindfulness was associated with increased aggression (physical, verbal, and aggressive attitude). Moreover, this relation held for both verbal aggression and aggressive attitude after controlling for alcohol use, drug use, and age, all known predictors of aggression. Findings provide the first evidence that mindfulness is negatively associated with aggression among men in substance use treatment, which could have important implications for intervention. That is, mindfulness-based interventions may prove helpful for the treatment of both substance use and aggression. © The Author(s) 2014.

2009-01-01

Detoxification of ti-ee gossypol (FG) in cottonseed meal (CSM) by Saccharomyces cerevisiae and Aspergillus niger, as a mixed culture, was carried out in solid state fermentation (SSF). Experiments were adopted to optimize the fermentation conditions. Maximum detoxification efficiency (90.2%) occurred after 48 h of incubation at 30 degree C in a 250 ml conical flask containing 15 g of CSM supplemented with 1 % (w/w) (NH 4 ) 2 SO 4 at the optimal conditions including the initial moisture content 55% (w/w) and inoculum level at 5% (v/w). The detoxification of FG was a growth-associated process, which was highly correlated with the dry matter weight loss. Moreover, high activities of hydrolytic enzymes were also produced in solid state fermentation, which enhanced the nutritive value of the detoxified cottonseed powder. A total number of 48 white New Zealand male rabbits were used to biologically examine the feeding of treated (detoxified) CSM without any adverse effects. Hematological and biochemical relevant parameters of white New Zealand male rabbits as affected by feeding treated meal were in the normal physiological range without no obvious change. No significant changes in liver and kidney functions of the rabbits weight gain, feed conversion and efficiency did not significantly change among experimental groups. The study showed that the feeding of the detoxified CSM by S. cerevisiae and A. niger as a mixed culture in this research without any adverse effects on rabbits

The application of pyrolytic sugars for biofuel production through fermentation is challenged by inhibitory contaminant compounds. Inhibition is so severe that only 0.25% sugar syrup can be used. In this study, overliming was tested as a simple detoxification method, using the Escherichia coli KO11+ lgk to directly convert levoglucosan into ethanol. After treatment with at least 14.8 g/L of Ca(OH)2, fermentation with 2% (w/v) pyrolytic sugar syrup was observed with no inhibition of ethanol production. Further investigation of treatment time and temperature showed that 8-16 h of treatment at 20°C, and 1-4 h of treatment at 60°C are necessary to obtain consistent ethanol production. The samples treated with 18.5 g/L Ca(OH)2 at 60°C for 4 h showed no inhibition at 2.5%. Multiple contaminants removed by the overliming treatment were identified. This study demonstrates that overliming is a promising method for detoxification of pyrolytic sugars for fermentation. Copyright © 2013 Elsevier Ltd. All rights reserved.

2016-01-01

Previous studies have reported changes in nutrition-related behaviors in alcohol-dependent patients after alcohol detoxification, but prospective studies assessing the effects of these changes on maintaining abstinence are lacking. To assess changes in craving and consumption of chocolate and other sweets over time up to six months after outpatient alcohol detoxification treatment and to detect differences in abstinent versus nonabstinent patients. One hundred and fifty alcohol-dependent patients were included in this prospective observational study. Participants completed self-report questionnaires on nutrition-related behaviors and craving before detoxification treatment (baseline, t1), one week (t2), one month (t3), and six months later (t4). Significant changes in craving for and consumption of chocolate as well as in craving for other sweets were observed over time. Increases were most prominent within the first month. Patients who remained abstinent until t3 consumed three times more chocolate than nonabstainers. One quarter of the patients switched from being rare (t1) to frequent (t3) chocolate eaters, and 84% of these remained abstinent until t3. No significant correlations were found between craving for alcohol and craving for or consumption of chocolate or other sweets. In the first month after outpatient alcohol detoxification treatment, significant changes in nutrition-related behaviors were observed. These changes were not associated with alcohol craving. For a subgroup, increasing the frequency of chocolate consumption might be a temporary protective factor with respect to alcohol relapse.

Full Text Available Abstract Background Methamphetamine (METH use, especially in females, has become a growing public health concern in China. In this study, we aimed to characterize the factors that contributed to drug craving in female METH users under isolated compulsory detoxification. We characterized factors contributing to craving such as duration of detoxification, history of drug use and self-reported mood state. Methods Subjects (N=113 undergoing a 1- to 3-year METH detoxification program were recruited from the Zhejiang Compulsory Detoxification Center for Women. The Questionnaire of METH-use Urge (QMU was used to evaluate the level of craving for METH. The Abbreviate Profile of Mood States (A-POMS was applied as an assessment for the negative mood disturbances. Results The participants were at a mean age of 25.2, primarily lowly educated and unemployed, and single. Smoking was the only route of METH administration at an average dose of 0.5 g/day, and 4 times/week. The reported craving level was positively correlated with the negative mood disturbances and the weekly dose of METH, but independent of the duration of detoxification. Furthermore, all five aspects of negative mood disturbances, including fatigue, bewilderment, anxiety, depression and hostility, were shown to positively correlate to the self-reported craving level after controlling for weekly dose of METH. Conclusions The data demonstrate a robust correlation between mood distress and craving for METH. Our results call for close evaluation of mood distress in treatment of METH users in China.

Full Text Available Abstract Background Seeking treatment in formal healthcare for uncomplicated infections is vital to combating disease in low- and middle-income countries (LMICs. Healthcare treatment-seeking behaviour varies within and between communities and is modified by socio-economic, demographic, and physical factors. As a result, it remains a challenge to quantify healthcare treatment-seeking behaviour using a metric that is comparable across communities. Here, we present an application for transforming individual categorical responses (actions related to fever to a continuous probabilistic estimate of fever treatment for one country in Sub-Saharan Africa (SSA. Methods Using nationally representative household survey data from the 2013 Demographic and Health Survey (DHS in Namibia, individual-level responses (n = 1138 were linked to theoretical estimates of travel time to the nearest public or private health facility. Bayesian Item Response Theory (IRT models were fitted via Markov Chain Monte Carlo (MCMC simulation to estimate parameters related to fever treatment and estimate probability of treatment for children under five years. Different models were implemented to evaluate computational needs and the effect of including predictor variables such as rurality. The mean treatment rates were then estimated at regional level. Results Modelling results suggested probability of fever treatment was highest in regions with relatively high incidence of malaria historically. The minimum predicted threshold probability of seeking treatment was 0.3 (model 1: 0.340; 95% CI 0.155–0.597, suggesting that even in populations at large distances from facilities, there was still a 30% chance of an individual seeking treatment for fever. The agreement between correctly predicted probability of treatment at individual level based on a subset of data (n = 247 was high (AUC = 0.978, with a sensitivity of 96.7% and a specificity of 75.3%. Conclusion We have shown

Full Text Available Objective: to evaluate the efficiency of extracorporeal detoxification techniques in patients with abdominal sepsis. Subjects and methods. Three hundred and seventy-nine patients with acute generalized peritonitis were examined. Extracorporeal detoxifying techniques were used during conventional therapy in Group 1 (n=319; the other patients received only traditional therapy (a control group. The time course of changes in the parameters of toxemia, a hemostasiogram, and an immunogram were examined. Results. The study indicated significantly reduced endotoxemia and better blood aggregation resulting from the use of plasmapheresis, cryoplasmasorption, and plasmasorption, as well as stimulated immunity when the above techniques were combined with autoblood photomodification and extracorporeal immunopharmacotherapy in patients with abdominal sepsis. In severe abdominal sepsis and infectious-toxic shock, there was regression of multiple organ dysfunction and lower mortality when venovenous hemofiltration was applied. Conclusion. A differential approach to using active detoxifying techniques is needed, by taking into account the severity of the disease. Key words: abdominal sepsis, detoxifying techniques.

Patient navigation pathway and barriers to treatment seeking in cancer in India: a qualitative inquiry.

2013-12-01

Cancer is a leading cause of mortality worldwide. Early diagnosis and treatment of cancer may curb the growing burden of the disease. Understanding cancer patients' navigation pathways for seeking treatment is important in order to facilitate early diagnosis and treatment. With this background we conducted a hospital-based cross-sectional study comprising 68 randomly selected cancer inpatients in a tertiary cancer specialty hospital in Odisha, India, to explore the treatment-seeking pathways of the cancer patients and the barriers and enablers in seeking treatment. Financial constraint is one of the major reasons for the delay in accessing treatment, even when patients are suspected of or diagnosed with cancer. Low awareness of the presenting signs and symptoms of cancer and limited knowledge of the availability of cancer diagnosis and treatment facilities are major factors contributing to delay. Family and friends' support is found to be the major enabling factor toward seeking treatment. Generation of awareness of cancer among the general population and primary-care practitioners - including those in alternative systems of medicine - is important. Information on diagnostic and treatment services appears to be a felt need. Copyright © 2013 Elsevier Ltd. All rights reserved.

Currier, Joseph M; McDermott, Ryon C; McCormick, Wesley H

2017-11-01

Record numbers of military veterans are enrolling at colleges/universities across the United States. Although a substantive subset might suffer from mental health problems, the majority of these students might not be amenable to utilizing services. The purpose of this study was to examine the role of treatment-related stigma in intentions to seek professional help among undergraduate student veterans at a university on the U.S. Gulf Coast. Focusing on 251 veterans and a gender-matched comparison group of 251 nonveterans, student veterans endorsed higher probabilities of seeking care from physicians (d = .77) and psychologists or other professionals (d = .67). In addition, nonveteran students had greater self-stigma about seeking help (d = -.27) but veterans had more negative beliefs about treatment efficacy (d = 1.07). When compared with veterans who did not exceed clinical thresholds, those with a probable need for treatment had more stigma (ds = .63). Multivariate analyses also revealed an inverse main effect of self-stigma on intentions to seek help from both professional categories. However, military experience differentially moderated associations between treatment-related beliefs and intentions to seek mental health services. Finally, exploratory analyses identified that student veterans were most likely to engage in therapy/counseling at a Veterans Affairs Medical Center or Clinic, Vet Center, or other noninstitutionally sponsored settings in the community (e.g., private practices, faith-based organizations). Looking ahead, these findings will inform research and the provision of services for addressing the mental health needs of this substantive subpopulation of college students in the United States.

Detoxification of pentachlorophenol-containing wood preserving waste was monitored under ambient, enhanced and chemical pretreatment conditions for genotoxicity and parent compound removal. Samples were collected throughout the treatment periods and sequentially extracted with dichloromethane and methanol with the Tecator Soxtec apparatus. The organic extracts were analyzed on GC/ECD and GC/MS. The extract mutagenic and genotoxic potentials were evaluated with and without metabolic activation with the Salmonella Microsomal and E. coli Prophage Induction assays. The Salmonella mutagenic responses of extracts from Weswood soil amended with wood preserving waste and treated under ambient conditions were 2.0, 34.6 and 2.4 times greater than the solvent control on days 0, 540 and 1,200 respectively. Organic extracts of soil amended with wood preserving waste and treated under enhanced conditions in a solid-phase rotating drum bioreactor had mutagenic potentials of 3.4, 4.9 and 3.5 on days 0, 14 and 30, respectively. Extracts from wood preserving waste sludge treated with potassium polyethylene glycol were shown to have mutagenic potentials of 2.8, 6.1 and 3.8 at 0, 10 and 30 minutes. The results indicate that the initial products of the wood preserving waste detoxification under all treatment conditions appear to have greater genotoxic potentials than the starting material. The results also suggest that a more rapid detoxification occurs under enhanced and chemical pretreatment conditions.

The Screen for Child Anxiety and Related Emotional Disorder (SCARED) may be differentially sensitive to detecting specific or comorbid anxiety diagnoses in treatment-seeking and non-treatment-seeking youth. We assessed the SCARED's discriminant validity, diagnostic utility, and informant agreement using parent- and self-report from healthy and treatment-seeking anxious youth (Study 1, N=585) and from non-treatment-seeking anxious youth (Study 2, N=331) diagnosed with generalized anxiety disorder (GAD), social anxiety disorder (SAD), or comorbid GAD+SAD. Among treatment-seeking youth, the SCARED showed good diagnostic utility and specificity, differentiating healthy, comorbid, and non-comorbid anxious youth. Child-parent agreement was modest: healthy child self-reports were higher than parent-reports whereas anxious child self-reports were similar or lower than parent-reports. Less consistent results emerged for diagnostic utility, specificity, and informant agreement among non-treatment-seeking youth. Given the number of non-treatment seeking anxious youth (N=33), generalizability of these findings may be limited. Together, results suggest informants may provide distinct information about children's anxiety symptoms. Copyright © 2017 Elsevier Ltd. All rights reserved.

Previous studies have not examined patterns of pain treatment use among patients seeking office-based buprenorphine-naloxone treatment (BNT) for opioid dependence. Objectives To examine, among individuals with pain seeking BNT for opioid dependence, the use of pain treatment modalities, perceived efficacy of prior pain treatment, and interest in pursuing pain treatment while in BNT. Methods 244 patients seeking office-based BNT for opioid dependence completed measures of demographics, pain status (i.e. “chronic pain (CP)” [pain lasting at least 3 months] vs. “some pain (SP)” [pain in the past week not meeting the duration criteria for chronic pain]), pain treatment use, perceived efficacy of prior pain treatment, and interest in receiving pain treatment while in BNT. Results In comparison to the SP group (N = 87), the CP group (N = 88) was more likely to report past-week medical use of opioid medication (AOR 3.2, 95% CI 1.2–8.4), lifetime medical use of non-opioid prescribed medication (AOR 2.2, 95% CI 1.1–4.7), and lifetime use of prayer (AOR 2.8, 95% CI 1.2–6.5), and was less likely to report lifetime use of yoga (AOR 0.2, 95% CI 0.1–0.7) to treat pain. While the two pain groups did not differ on levels of perceived efficacy of prior lifetime pain treatments, in comparison to the SP group, the CP group was more likely to report interest in receiving pain treatment while in BNT (P pain seeking BNT for opioid dependence report a wide range of conventional, complementary, and alternative pain-related treatments and are interested (especially those with CP) in receiving pain management services along with BNT.

2012-06-01

A random digit dialing telephone survey was used to interview 8,467 adults in Ontario, Canada. The NODS-CLiP was used to identify a representative sample of 730 gamblers (54.3% male, mean age 45.3 years) with possible past year gambling problems in order to explore factors that might affect disordered gamblers' motivators for seeking gambling-related help. A final sample of 526 gamblers provided useable data on possible reasons for and barriers to seeking help, awareness of services, self-perception of gambling problems and experience with help-seeking. Financial and relationship issues were the most frequently volunteered motivators. However, over two-thirds of the respondents could not think of a reason for seeking help. Gamblers who had self-admitted or more severe problems, who knew how to get help, who were employed and had more education, and who identified possible barriers to seeking help were more likely to suggest motivators, especially financial ones. More research is recommended on gamblers' trajectory towards recognition of a gambling problem, the process of overcoming specific barriers to treatment, and the role of social advantage (e.g., education and employment), in order to devise educational campaigns that will encourage earlier help-seeking among disordered gamblers.

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

Ebola Treatment Units were able to provide only 60% of necessary treatment beds in Sierra Leone. As a result, the Government of Sierra Leone decided to construct Community Care Centers. These were intended to increase treatment-seeking behavior and reduce the community-level spread of Ebola by facilitating access to care closer to communities. Through qualitative data collection in 3 districts, this study seeks to understand the perceived impact that proximity to such Centers had on treatment-seeking behavior. Feedback from community members and Community Health Volunteers indicates that proximity to treatment reduced fears, especially those arising from the use of ambulances, lack of familiarity with medical Centers, and loss of contact with family members taken for treatment. Participants report that having a Center close to their home enables them to walk to treatment and witness survivors being discharged. Living close to Centers also enables communities to be involved in their design and daily operation, helping to build trust in them as acceptable treatment facilities. Further research is required to understand the appropriate design, operation, and epidemiological impact of Centers. Further investigation should incorporate the effect of an outbreak's severity and the stage (duration) of the outbreak on potential acceptance of Centers.

Full Text Available The objective of this study was to evaluate prediction factors for failure to seek treatment following a traumatic dental injury (TDI to primary teeth among preschool children in the city of Campina Grande, Brazil. A cross-sectional study was carried out involving 277 children 3 to 5 years of age, with TDI, enrolled in public and private preschools. Parents filled out a form addressing demographic data and whether or not they had sought treatment. Clinical examinations were performed by three dentists who had undergone a calibration exercise (Kappa: 0.85 to 0.90 for the evaluation of TDI. Bivariate and multivariate Poisson regression models were constructed (α = 5%. Enamel fracture was the most prevalent type of TDI (48.7% and the upper central incisors were the most affected teeth (88.4%. The frequency of seeking dental treatment was low (9.7%. The following variables were associated with failure to seek treatment following TDI: a household income greater than one minimum wage (PR = 1.170; 95%CI 1.018-1.341, parents/caregivers’ perception of a child’s oral health as poor (PR = 1.100; 95%CI 1.026-1.176, and the non-perception of TDI by parents/caregivers (PR = 1.250; 95%CI 1.142-1.360. In the present study, the frequency of seeking treatment following TDI was low, and parents/caregivers with a higher income, a poor perception of their child’s oral health and a lack of awareness regarding the trauma were more likely to fail to seek treatment following TDI to primary teeth.

Infertility is an emergent issue in India. Until recently, very few studies have understood the patterns and consequences of infertility in India. Family planning programs in India also viewed exclusively the patterns and determinants of overfertility rather than infertility. Furthermore, there is the lack of information about treatment seeking behavior of infertile couples. Therefore, this paper aimed to examine the extent of infertility and treatment seeking behavior among infertile women in India. An attempt was also made to evaluate the effects of socio-demographic factors on treatment seeking behavior. The study used the data from the District Level Household and Facility Survey carried out in India during 2007-08. Several statistical techniques such as chi-square test, proportional hazard model and binary logistic regression model were used for the analysis. Approximately, 8% of currently married women suffered from infertility in India and most of them were secondary infertile (5.8%). Within India, women's infertility rate was the highest in west Bengal (13.9 percent) and the lowest in Meghalaya (2.5 percent). About 80% of infertile women sought treatment but a substantial proportion (33%) received non-allopathic and traditional treatment due to expensive modern treatment and lack of awareness. In the context of policy response, it can be said that there is a need to improve the existing services and quality of care for infertile women. Treatment for infertility should be integrated into the larger reproductive health packages.

Studies on small samples or in single units applying specific treatment programmes found an association between some personality traits and attrition and weight loss in individuals treated for obesity. We aimed to investigate whether pre-treatment personality traits were associated with weight loss outcomes in the general population of women with obesity. Attrition and weight loss outcomes after 12 months were measured in 634 women with obesity (mean age, 48; body mass index (BMI), 37.8 kg m(-2)) seeking treatment at eight Italian medical centres, applying different medical/cognitive behavioural programmes. Personality traits were assessed with the Temperament and Character Inventory (TCI), eating disorder features with the Binge Eating Scale (BES) and Night Eating Questionnaire (NEQ). Within the 12-month observation period, 32.3% of cases were lost to follow-up. After adjustment for demographic confounders and the severity of eating disorders, no TCI personality traits were significantly associated with attrition, while low scores of the novelty seeking temperament scale remained significantly associated with weight loss ≥ 10% (odds ratio, 0.983; 95% confidence interval, 0.975-0.992). Additional adjustment for education and job did not change the results. We conclude that personality does not systematically influence attrition in women with obesity enrolled into weight loss programmes in the community, whereas an association is maintained between novelty seeking and weight loss outcome. Studies adapting obesity interventions on the basis of individual novelty seeking scores might be warranted to maximize the results on body weight. © 2015 World Obesity.

To estimate the prevalence of ADHD and determine an effective screening test for ADHD in a population-seeking treatment for cannabis use disorders. The Conners Adult ADHD Diagnostic Interview forDiagnostic and Statistical Manual of Mental Disorders, Fourth Edition(DSM-IV; CAADID) was used to generate sensitivity and specificity data for ADHD screening tests, which were then administered to 99 participants seeking treatment for cannabis use disorders to estimate ADHD prevalence. The prevalence estimated from the Wender Utah Rating Scale (WURS) was 45% (sensitivity = 0.88, sensitivity of 0.75), from the Conners Adult ADHD Rating Scale (CAARS) 34% (sensitivity = 0.80, specificity = 0.91), from the WURS + CAARS 36% (sensitivity = 0.71, specificity = 0.95), and from the Adult ADHD Self-Report Scale (ASRS) 46% (sensitivity = 0.61, specificity = 0.86). The prevalence of ADHD in adults seeking treatment for cannabis use disorders is estimated to be between 34% and 46%. The WURS paired with the CAARS provides excellent sensitivity and specificity for the diagnosis of ADHD in this population. © The Author(s) 2016.

Current biomass pretreatment by hydrothermal treatment (including acid hydrolysis, steam explosion, and high-temperature steaming) and ionic liquids generally generate inhibitors to the following fermentation process. Furfural is one of the typical inhibitors generated in hydrothermal treatment of biomass. Furfural could inhibit cell growth rate and decrease biofuel productivity of microbes. Candida tropicalis is a promising microbe for the production of biofuels and value-added chemicals using hemicellulose hydrolysate as carbon source. In this study, C. tropicalis showed a comparable ability of furfural tolerance during fermentation. We investigated the mechanism of C. tropicalis 's robust tolerance to furfural and relevant metabolic responses to obtain more information for metabolic engineering of microbes for efficient lignocellulose fermentation. Candida tropicalis showed comparable intrinsic tolerance to furfural and a fast rate of furfural detoxification. C. tropicalis 's half maximal inhibitory concentration for furfural with xylose as the sole carbon source was 3.69 g/L, which was higher than that of most wild-type microbes reported in the literature to our knowledge. Even though furfural prolonged the lag phase of C. tropicalis , the final biomass in the groups treated with 1 g/L furfural was slightly greater than that in the control groups. By real-time PCR analysis, we found that the expression of ADH1 in C. tropicalis ( ctADH1 ) was induced by furfural and repressed by ethanol after furfural depletion. The expression of ctADH1 could be regulated by both furfural and ethanol. After the disruption of gene ctADH1 , we found that C. tropicalis 's furfural tolerance was weakened. To further confirm the function of ctADH1 and enhance Escherichia coli 's furfural tolerance, ctADH1 was overexpressed in E. coli BL21 (DE3). The rate of furfural degradation in E. coli BL21 (DE3) with pET-ADH1 (high-copy plasmid) and pCS-ADH1 (medium-copy plasmid) was increased

Gender differences in patterns and consequences of substance use, treatment-seeking, and motivation to change were examined in two samples of people with serious mental illness (SMI) and comorbid substance use disorders (SUDs): a community sample not currently seeking substance abuse treatment (N = 175) and a treatment-seeking sample (N = 137). In both groups, women and men demonstrated more similarities in the pattern and severity of their substance use than differences. However, treatment-seeking women showed greater readiness to change their substance use. Mental health problems and traumatic experiences may prompt people with SMI and SUD to enter substance abuse treatment, regardless of gender.

Many adults suffering from mental disorders never receive the care they need. The role of family and friends in overcoming mental health treatment barriers is poorly understood. We investigated the association between awareness of lifetime mental health treatment history in one's family or friends, and likelihood of having recently received mental health care for oneself. Using Canadian Community Health Survey 2012-Mental Health data, we defined care seekers as individuals who talked about mental health issues to at least one health professional in the past 12 months. Seekers were matched to non-seekers based on estimated care seeking propensity, and 1933 matched pairs were created. Reported awareness of lifetime treatment history in family and friends was compared between seekers and non-seekers. There were no differences in the distribution of any confounder of interest between seekers and non-seekers. 73% of seekers were aware of treatment history in family or friends, compared to only 56% of non-seekers (RR 1.3; 95% CI 1.2, 1.3). Awareness of treatment history in family members had nearly identical associations with care seeking as awareness of treatment history in friends. We have found a social clustering of mental health care seeking behavior; individuals who were aware of lifetime treatment history in family or friends were more likely to have recently sought care for themselves. These novel results are consistent with a social learning model of care seeking behavior, and could inform efforts to bridge the current mental health treatment gap.

Detoxification programmes seek to implement the most secure and compassionate ways of withdrawing from opiates so that the inevitable withdrawal symptoms and other complications are minimized. Once detoxification has been achieved, the next stage is to enable the patient to overcome his or her drug addiction by ensuring consumption is permanently and completely abandoned, only after which can the subject be regarded as fully recovered. A systematic search on the common databases of relevant papers published until 2016 inclusive. Our study of the available oral treatments for opioid dependence has revealed that no current treatment can actually claim to be fully effective. These treatments require daily oral administration and, consequently, regular visits to dispensaries, which in most cases results in a lack of patient compliance, which causes fluctuations in drug plasma levels. We then reviewed alternative treatments in the available scientific literature on polymeric sustained release formulations. Research has been done not only on release systems for detoxification but also on release systems for giving up the habit of taking opioids. These efforts have obtained the recent authorization of polymeric systems for use in patients that could help them to reduce their craving for drugs.

Current knowledge of detoxification mechanisms of xenobiotic in honey bees.

Gong, Youhui; Diao, Qingyun

The western honey bee Apis mellifera is the most important managed pollinator species in the world. Multiple factors have been implicated as potential causes or factors contributing to colony collapse disorder, including honey bee pathogens and nutritional deficiencies as well as exposure to pesticides. Honey bees' genome is characterized by a paucity of genes associated with detoxification, which makes them vulnerable to specific pesticides, especially to combinations of pesticides in real field environments. Many studies have investigated the mechanisms involved in detoxification of xenobiotics/pesticides in honey bees, from primal enzyme assays or toxicity bioassays to characterization of transcript gene expression and protein expression in response to xenobiotics/insecticides by using a global transcriptomic or proteomic approach, and even to functional characterizations. The global transcriptomic and proteomic approach allowed us to learn that detoxification mechanisms in honey bees involve multiple genes and pathways along with changes in energy metabolism and cellular stress response. P450 genes, is highly implicated in the direct detoxification of xenobiotics/insecticides in honey bees and their expression can be regulated by honey/pollen constitutes, resulting in the tolerance of honey bees to other xenobiotics or insecticides. P450s is also a key detoxification enzyme that mediate synergism interaction between acaricides/insecticides and fungicides through inhibition P450 activity by fungicides or competition for detoxification enzymes between acaricides. With the wide use of insecticides in agriculture, understanding the detoxification mechanism of insecticides in honey bees and how honeybees fight with the xenobiotis or insecticides to survive in the changing environment will finally benefit honeybees' management.

Two repurposed medications have been proposed to treat cocaine abuse. Progesterone, a gonadal hormone, and atomoxetine, a medication commonly used to treat attention deficit/hyperactivity disorder, have both been separately shown to reduce cocaine self-administration and reinstatement (i.e., relapse). The goal of the present study was to examine sex differences in the individual effects of PRO and ATO as well as the combination PRO+ATO treatment on cocaine (COC), caffeine (CAF), and/or cue-primed reinstatement of cocaine-seeking. Adult male and female Wistar rats lever-pressed under a FR 1 schedule for cocaine infusions (0.4mg/kg/inf). After 14 sessions of stable responding in daily 2-h sessions, rats underwent a 21-day extinction period when no drug or drug-related stimuli were present. Rats were then separated into four groups that received PRO (0.5mg/kg) alone (PRO+SAL), ATO (1.5mg/kg) alone (VEH+ATO), control (VEH+SAL) or combination (PRO+ATO) treatments prior to the reinstatement condition. Reinstatement of cocaine-seeking to cues and/or drug injections of cocaine or caffeine was tested after extinction. During maintenance, females self-administered more cocaine than males, but no sex differences were seen during extinction. Females showed greater cocaine-seeking than males after a CAF priming injection. Individual treatment with ATO did not decrease reinstatement under any priming condition; however, the combination treatment decreased cocaine-seeking under the COC+CUES priming condition in males, and both PRO alone and the combination treatment decreased cocaine-seeking in the CAF+CUES condition in females. Overall, PRO alone was only effective in reducing reinstatement in females, while the combination treatment was consistently effective in reducing reinstatement in both sexes.

Vaginal discharge (safed pani in Hindi, meaning "white water") is one of the leading symptoms for which women in India seek care. Treatment-seeking for safed pani is disproportionately high among poor women, representing a physical, emotional and financial burden for low-income families. Safed pani is only rarely indicative of a reproductive tract or sexually transmitted infection. The discrepancy between symptom reports and observed pathology has led some researchers to characterize safed pani as a culturally based expression of more generalized negative life situation. Data are drawn from two prevention intervention studies (2002-2006 and 2007-2012) conducted in economically marginal communities in Mumbai. Results show that husbands as problem generators and spousal abusers and women's greater perceived empowerment and reported tension are significantly associated with safed pani. These results provide the basis for identifying women at greater risk for psychosocial distress and providing supports at the locations at which they seek treatment.

Ethanol from lignocellulose - Fermentation inhibitors, detoxification and genetic engineering of Saccharomyces cerevisiae for enhanced resistance

Energy Technology Data Exchange (ETDEWEB)

Larsson, Simona

2000-07-01

Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars, and then fermenting the hydrolysate with the yeast Saccharomyces cerevisiae. Hydrolysis using dilute sulphuric acid has advantages over other methods, however, compounds which inhibit fermentation are generated during this kind of hydrolysis. The inhibitory effect of aliphatic acids, furans, and phenolic compounds was investigated. The generation of inhibitors during hydrolysis was studied using Norway spruce as raw material. It was concluded that the decrease in the fermentability coincided with increasing harshness of the hydrolysis conditions. The decrease in fermentability was not correlated solely to the content of aliphatic acids or furan derivatives. To increase the fermentability, detoxification is often employed. Twelve detoxification methods were compared with respect to the chemical composition of the hydrolysate and the fermentability after treatment. The most efficient detoxification methods were anion-exchange at pH 10.0, overliming and enzymatic detoxification with the phenol-oxidase laccase. Detailed analyses of ion exchange revealed that anion exchange and unspecific hydrophobic interactions greatly contributed to the detoxification effect, while cation exchange did not. The comparison of detoxification methods also showed that phenolic compounds are very important fermentation inhibitors, as their selective removal with laccase had a major positive effect on the fermentability. Selected compounds; aliphatic acids, furans and phenolic compounds, were characterised with respect to their inhibitory effect on ethanolic fermentation by S. cerevisiae. When aliphatic acids or furans were compared, the inhibitory effects were found to be in the same range, but the phenolic compounds displayed widely different inhibitory effects. The possibility of genetically engineering S. cerevisiae to achieve increased inhibitor resistance was explored by heterologous expression of

Full Text Available OBJETIVE: Greater information regarding motivations and treatment barriers faced by substance-dependent individuals has clinical and public health implications. This study aimed to formulate hypotheses regarding psychological, social and family variables that can be constructed as motivations or subjective barriers for the early seeking of formal treatment. METHODS: A qualitative study was conducted in an intentional sample (selected through saturation and variety of types of 13 substance-dependent individuals who sought treatment. In-depth, semi-structured interviews were conducted using open questions, and the transcribed data were subjected to qualitative analysis. RESULTS: Four types of spontaneous harm reduction measures were identified, according to the subjective logic of each participant: having some periods at rest (not using and recovering from adverse effects; caretaking by close acquaintances (relatives, partners, drug dealers and alcoholic beverage sellers; selectivity regarding substance source, type and means of administration; establishing "healthy" limits of ingestion. CONCLUSIONS: The measures identified might represent barriers to the early seeking of treatment but might also represent spontaneous learning of abilities beneficial to future treatment. Health care professionals should take into consideration their existence and should address them in clinical settings. Issues representative of the formulated categories should be presented in structured questionnaires used in future quantitative studies of barriers to treatment in this population.

Despite significant mental health needs among sexual assault (SA) victims in the military, little is known about treatment-seeking patterns or factors associated with service use. This study examined service use behavior, barriers, and facilitators of mental health treatment-seeking in an active duty sample of 927 U.S. Army soldiers with mental health problems. SA victims (n = 113) did not differ from non-victims on barriers or facilitators after adjusting for demographic and mental health variables, with stigma rated as the largest barrier. Most SA victims (87.6%) had sought informal support and 59.3% had sought formal treatment. One third of treatment-seekers had dropped out of treatment. Multivariate logistic regression analyses identified several correlates of treatment-seeking among SA victims: Black race (OR = 7.57), SA during the military (OR = 4.34), positive treatment beliefs (OR = 2.22), social support for treatment (OR = 2.14), self-reliance (OR = 0.47), and stigma towards treatment seekers (OR = 0.43). Mental health symptoms were not associated with treatment seeking. Findings suggested that treatment-facilitating interventions should focus on improving recognition of mental health symptoms, altering perceptions related to self-reliance, and reducing stigma. Interventions should also enlist support for treatment-seeking from unit members, leaders, and significant others. © 2015 International Society for Traumatic Stress Studies.

Cheng, Tyrone C; Lo, Celia C

2014-01-01

A study with 591 low-income women examined domestic violence's role in treatment seeking for mental health or substance abuse problems. (The women resided in one of two California counties.) Following Aday's behavioral model of health services utilization, the secondary data analysis considered the women's need, enabling, and predisposing factors. Generalized estimating equations analyzed the women's longitudinal records of treatment seeking. Results showed that those in the sample who were likely to seek treatment had experienced three or more controlling behaviors and only one abusive behavior. Multivariate data analysis showed treatment-seeking women were likely to be white and older; responsible for few dependent children; not graduates of high school; employed; not participating in Medicaid; diagnosed; and perceiving a need for treatment. The implications of these results for services and policies are discussed.

The World Health Organization estimates that 340 million new cases of curable sexually transmitted infections (STIs) occur every year, while 33 million individuals are estimated to be living with HIV. The AIDS and STI epidemics are not independent with untreated STIs increasing HIV acquisition and transmission. Female sex workers have increased prevalence of untreated STIs and have been hypothesized to affect the health and HIV incidence of the general population. This paper aims to investigate why some female sex workers who experience symptoms of vaginal discharge or genital ulcers seek treatment while others do not. Data were collected from a cohort study conducted between 2002 and 2005 among female bar and hotel workers in Moshi, Tanzania. Study subjects were recruited from 7 out of 15 administrative wards in Moshi as part of the Moshi's Women's Health Project. Data were restricted to women self-reporting symptoms of vaginal discharge or genital ulcers (n=459) within the past year. Logistic regression was performed with SAS 9.1. Qualitative analysis was performed using in-depth interviews and focus group discussions among a convenience sample (n=42) of women already enrolled in the study. All interviews and focus group discussions were tape-recorded and transcribed, and data were analyzed thematically. Sixty-four percent of the sample sought treatment for either ailment. Multivariate analysis identified relationship to man of last sexual intercourse, ever experiencing a pregnancy, and age as significant predictors to seeking treatment. Four salient themes of threats to fertility, stigma correlated with prostitution, discomfort with the physical exam, and perceived views of clients were revealed as predictors to why women seek or intentionally ignore symptoms. Understanding the motivations and barriers for seeking treatment of STIs has far ranging public health implications that could help curtail the unnecessary associated morbidity and mortality and curtail

Despite the high rate of smoking cessation treatment non-response, relatively little empirical work has examined predictors of treatment non-response. The present study sought to explore the effect of smoking outcome expectancies on treatment response in a sample of treatment-seeking adult daily smokers (N=182; 53.3% female; M age =40.67; SD=13.63). Results indicated that expectancies for smoking to reduce negative affect were related to an increased likelihood of treatment non-response (OR=0.73, CI: 0.54, 0.98). These findings remained significant after controlling for sex, presence of Axis I disorder, tobacco-related health problems, tobacco dependence, anxiety sensitivity, and condition assignment as well as other smoking expectancy dimensions. Post hoc analyses revealed that this relation was stronger for smokers in the integrated care condition vs. the standard care condition (Interaction: OR=1.69, CI: 1.05, 2.73). Additionally, expectancies for smoking to enhance positive affect and provide sensory satisfaction were associated with an increased likelihood of treatment response in the standard care condition. The current findings suggest expectancies that smoking will alleviate negative affect may be a risk factor of smoking cessation treatment non-response. Additionally, findings provide evidence that the relation between smoking expectancies and treatment non-response may differ by smoking cessation treatment. Copyright © 2017 Elsevier Ltd.

The aim of this study was to evaluate the psychosocial impact of dental esthetics for adults seeking orthodontic treatment. The Chinese version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) was administered to 393 adults, aged 18 to 30 years. The participants were divided into 2 groups: an intervention group (received orthodontic treatment) and a control group (rejected orthodontic treatment). Baseline malocclusion severity was assessed using the Index of Orthodontic Treatment Need (IOTN). The Wilcoxon signed rank test showed no statistically significant difference between the groups for the dental health component (DHC) of the IOTN (P = 0.134). Total and subscale PIDAQ scores of the intervention group were higher than those of the control group and differed significantly in each group among the 4 IOTN-DHC grades; self-confidence scores in the control group (F = 1.802; P >0.05) were the exception. Correlations between the PIDAQ scores and the IOTN-DHC grades were strong in each group. DHC grades, psychological impact, social impact, and aesthetic concern had significant impacts on patients accepting orthodontic treatment. The psychosocial impact of dental esthetics played an important role in the decision-making process of adults seeking orthodontic treatment. Importantly, participants with low self-awareness of the potential psychosocial impact rejected orthodontic treatment, despite the need for severe normative treatment.

The study examined public and self-stigma and their association with attitudes and intentions to seek psychological help in regard to both individual and group treatment as well as to various subgroups, including gender, ethnicity, educational orientation, level of religion, and age. Undergraduate students (N=307) in three universities in Israel participated in the study. Results partly confirmed the model for both individual and group therapy: Self-stigma was related to attitudes and intentions to seek help. However, public stigma was not related to self-stigma. Importantly, some differences were also found among the various subgroups, and the model, which takes into account the different subgroups, looks somewhat different for individual and group therapy.

Three distinct textile samples were investigated for color and toxicity (S1–chemical/textile industry; S2–final textile effluent; S3 - standard textile produced effluent–untreated blue). Radiation processing of these samples were carried out at Dynamitron Electron Beam Accelerator and color and toxicity removal were determined: color removal by radiation was 96% (40 kGy, S1); 55% (2.5 kGy, S2) and 90% (2.5 kGy, S3). Concerning toxicity assays, Vibrio fischeri luminescent bacteria demonstrated higher reduction after radiation than the other systems: removal efficiencies were 33% (20 kGy, S1); 55% (2.5 kGy, S2) and 33% (2.5 kGy, S3). Daphnia similis and Brachionus plicatilis fitted well for S3 effluents. Hard toxic volumes into biological treatment plant may be avoided if radiation would be previously applied in a real plant. Results reveled how indispensable is to run toxicity to more than one living-organism. - Highlights: • 2.5 kGy was enough for decoloration and detoxification of S2 and S3. • S1 effluents were very toxic and required at least 20 kGy for detoxification. • Radiation processing reduced toxicity for 100% of treated samples. • V. fischeri was the best tool for toxicity measurements.

Detoxification with psychosocial counseling remains a standard opioid-use disorder treatment practice but is associated with poor outcomes. This study tested the efficacy of a newly developed psychosocial intervention, Community Reinforcement Approach and Family Training for Treatment Retention (CRAFT-T), relative to psychosocial treatment as usual (TAU), for improving treatment outcomes. A randomized, 14-week trial with follow-up visits at 6 and 9 months post-randomization conducted at two substance use disorder (SUD) treatment programs. Opioid-dependent adults (i.e., identified patient - IP) enrolled in a residential buprenorphine-detoxification program and their identified concerned significant other (CSO) was randomized to CRAFT-T (n=28 dyads) or TAU (n=24 dyads). CRAFT-T consisted of two sessions with the IP and CSO together and 10 with the CSO alone, over 14 weeks. TAU for the CSOs was primarily educational and referral to self-help. All IPs received treatment as usually provided by the SUD program in which they were enrolled. The primary outcome was time to first IP drop from treatment lasting 30 days or more. Opioid and other drug use were key secondary outcomes. CRAFT-T resulted in a moderate but non-significant effect on treatment retention (p=0.058, hazard ratio=0.57). When the CSO was parental family, CRAFT-T had a large and significant effect on treatment retention (pCRAFT-T had a significant positive effect on IP opioid and other drug use (pCRAFT-T is a promising treatment for opioid use disorder but replication is needed to confirm these results.

Full Text Available In recent years, the development of efficient green chemistry methods for detoxification of metal poisoning has become a major focus of researchers. They have investigated in order to find an eco-friendly and recyclable technique for the removal of heavy metal (Pb2+, Hg2+ contamination from the natural resources. One of the most considered methods is the removal of Pb2+, Hg2+ metal using green plants and their wastes. Among these plant wastes seem to be the best candidates and they are suitable for detoxification of heavy metals. Biosorption by plants involve complex mechanisms, mainly ion exchange, chelation, adsorption by physical forces and ion entrapment in inter and intra fibrillar capillaries and spaces of the structural polysaccharide cell wall network. The advantages of using green plants and their wastes for detoxification of heavy metal have interested researchers to investigate mechanisms of metal ion uptake, and to understand the possible utilization. In this review, we discuss the role of plants and their wastes for minimizing mercury and lead pollution with their toxic effect on both human beings and plants.

Opioid Addiction: Social Problems Associated and Implications of Both Current and Possible Future Treatments, including Polymeric Therapeutics for Giving Up the Habit of Opioid Consumption

Full Text Available Background. Detoxification programmes seek to implement the most secure and compassionate ways of withdrawing from opiates so that the inevitable withdrawal symptoms and other complications are minimized. Once detoxification has been achieved, the next stage is to enable the patient to overcome his or her drug addiction by ensuring consumption is permanently and completely abandoned, only after which can the subject be regarded as fully recovered. Methods. A systematic search on the common databases of relevant papers published until 2016 inclusive. Results and Conclusion. Our study of the available oral treatments for opioid dependence has revealed that no current treatment can actually claim to be fully effective. These treatments require daily oral administration and, consequently, regular visits to dispensaries, which in most cases results in a lack of patient compliance, which causes fluctuations in drug plasma levels. We then reviewed alternative treatments in the available scientific literature on polymeric sustained release formulations. Research has been done not only on release systems for detoxification but also on release systems for giving up the habit of taking opioids. These efforts have obtained the recent authorization of polymeric systems for use in patients that could help them to reduce their craving for drugs.

Full Text Available Deoxynivalenol (DON is a toxic secondary metabolite produced by several Fusarium species that infest wheat and corn. Food and feed contaminated with DON pose a health risk to both humans and livestock and form a major barrier for international trade. Microbial detoxification represents an alternative approach to the physical and chemical detoxification methods of DON-contaminated grains. The present study details the characterization of a novel bacterium, Devosia mutans 17-2-E-8, that is capable of transforming DON to a non-toxic stereoisomer, 3-epi-deoxynivalenol under aerobic conditions, mild temperature (25-30 oC, and neutral pH. The biotransformation takes place in the presence of rich sources of organic nitrogen and carbon without the need of DON to be the sole carbon source. The process is enzymatic in nature and endures a high detoxification capacity (3 µg DON/h/108 cells. The above conditions collectively suggest the possibility of utilizing the isolated bacterium as a feed treatment to address DON contamination under empirical field conditions.

Maria Romay-Barja

Full Text Available Malaria remains a major cause of morbidity and mortality among children under five years old in Equatorial Guinea. However, little is known about the community management of malaria and treatment-seeking patterns. We aimed to assess symptoms of children with reported malaria and treatment-seeking behaviour of their caretakers in rural and urban areas in the Bata District.A cross-sectional study was conducted in the district of Bata and 440 houses were selected from 18 rural villages and 26 urban neighbourhoods. Differences between rural and urban caregivers and children with reported malaria were assessed through the chi-squared test for independence of categorical variables and the t-Student or the non-parametric Mann-Whitney test for normally or not-normally distributed continuous variables, respectively.Differences between rural and urban households were observed in caregiver treatment-seeking patterns. Fever was the main symptom associated with malaria in both areas. Malaria was treated first at home, particularly in rural areas. The second step was to seek treatment outside the home, mainly at hospital and Health Centre for rural households and at hospital and private clinic for urban ones. Artemether monotherapy was the antimalarial treatment prescribed most often. Households waited for more than 24 hours before seeking treatment outside and delays were longest in rural areas. The total cost of treatment was higher in urban than in rural areas in Bata.The delays in seeking treatment, the type of malaria therapy received and the cost of treatment are the principal problems found in Bata District. Important steps for reducing malaria morbidity and mortality in this area are to provide sufficient supplies of effective antimalarial drugs and to improve malaria treatment skills in households and in both public and private sectors.

Full Text Available Objective: To investigate treatment seeking behaviour and the prevalence of treatment delay of malaria patients. Methods: A cross-sectional study was conducted with malaria patients along the ThailandMyanmar border in Tak province, Thailand. Results: Most of patients (70.0% were treated for fever before receiving treatment at a malaria clinic or public hospital. The sources of initial treatments were self-treatment (64.0%, malaria clinics (20.0%, public hospital (11.0%, sub-district health promotion hospital (3.3%, and malaria posts (1.1%. Prevalence of patients delayed more than one day after onset of symptoms was 79.4%, but doctor delay of more than one day occurred in only 1.3%. The prevalence of treatment delay (total delay of more than one day was 79.6%. Patient delay and treatment delay were found to be significantly higher among hill tribe than Thai subjects (P=0.004 and 0.003, respectively but, there was no significant association between ethnicity and doctor delay (P=0.669. Conclusion: Patient delay in seeking treatment is a major problem along the ThailandMyanmar border in Tak province, especially in hill tribe people. Self-treatment accounted for most of initial treatment sought by patients.

What Matters: Quantity or Quality of Pornography Use? Psychological and Behavioral Factors of Seeking Treatment for Problematic Pornography Use.

Gola, Mateusz; Lewczuk, Karol; Skorko, Maciej

2016-05-01

Pornography has become popular with Internet technology. For most people, pornography use (PU) is entertainment; for some, it can result in seeking treatment for out-of-control behavior. Previous studies have suggested that PU can influence sexual behaviors, but the direct relation between frequency of PU and treatment-seeking behaviors has not been examined. To investigate whether individuals seeking treatment as a consequence of their problematic PU do so because of their quantity of pornography consumption or because of more complex psychological and behavioral factors related to PU, such as the severity of negative symptoms associated with PU and/or subjective feeling of loss of control over one's behavior. A survey study was conducted of 569 heterosexual Caucasian men 18 to 68 years old, including 132 seeking treatment for problematic PU (referred by psychotherapists after their initial visit). The main outcome measures were self-reported PU, its negative symptoms, and actual treatment-seeking behavior. We tested models explaining sources of seeking treatment for problematic PU with negative symptoms associated with PU and additional factors (eg, onset and number of years of PU, religiosity, age, dyadic sexual activity, and relationship status). Seeking treatment was significantly, yet weakly, correlated solely with the frequency of PU (r = 0.21, P pornography consumption. Thus, treatment of problematic PU should address qualitative factors, rather than merely mitigating the frequency of the behavior, because frequency of PU might not be a core issue for all patients. Future diagnostic criteria for problematic PU should consider the complexity of this issue. Copyright © 2016 International Society for Sexual Medicine. Published by Elsevier Inc.

The objective of this work is To investigate the prevalence, comorbidities, impairment, and treatment-seeking of social anxiety disorder in the Chinese military personnel. Military personnel (n=11,527) were surveyed from May to August 2007 using a multistage whole cohort probability sampling method. A Chinese version of the World Health Organization Composite International Diagnostic Interview (CIDI) was used for assessment, and a military-related socio-demographic questionnaire was used to describe the prevalence distribution. A unified survey was performed to investigate 11 different social situations. The short-form health survey was used to assess role impairment. The 12-month and lifetime prevalence rates of social anxiety disorder were 3.34% (95% CI: 3.25-3.42%) and 6.22% (95% CI: 6.11-6.32%), respectively. Social anxiety disorder was associated with increased odds of depression, substance abuse, panic attacks/disorder, and generalized anxiety disorder. Childhood foster, female, stressful life events, younger age, and being divorced/widowed increase the incidence of social anxiety disorder. Treatment-seeking was relatively rare. Social anxiety disorder is a common disorder in military personnel in China, and it is a risk factor for subsequent depressive illness, substance abuse and other mental disorder. Early detection and treatment of social anxiety disorder are important because of the low rate of treatment-seeking. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

India is home to the highest number of adolescents in the world. Adolescents in India suffer from lack of knowledge and empowerment to make informed sexual and reproductive health decisions. This paper analyses the prevalence of reproductive tract infections and sexually transmitted infections (RTI/STI) and treatment seeking behavior among married adolescent women in India aged 15-19 years. Data from the District Level Household Survey (DLHS, 2007-08) of India were used. The prevalence of RTIs symptoms and treatment seeking behavior among women by different socio-demographic characteristics was analyzed. Factor analysis was utilized to create an index using information about 11 symptoms of RTI/STI collected in the survey. Linear and binary logistic regressions were used to know the association between infections and treatment seeking behavior with socio-demographic factors. About 15 percent of adolescent women reported having any symptoms of RTI/STI. The main symptoms reported were low backache, pain in the lower abdomen, pain during intercourse and itching or irritation around the vulvar region. Factor analysis showed the concentration of diseases in three clusters - infection in around the vulva, other reproductive infection and abnormal discharge; and intercourse related problems. Major predictors of both symptoms of reproductive infections and treatment seeking behavior from multivariate analysis are age, education, wealth, region and awareness about RTI/STI. Knowledge and treatment seeking behavior is poor among adolescent women in India. There is need for programmatic and policy emphasis on increasing knowledge and awareness through family life education including in educational curriculum at school level.

To examine the relationship between service use and outcomes (individual and wider consequences) using an economic analysis of a direct-access alcohol detoxification service in Manchester (the Smithfield Centre) and an NHS partial hospitalization programme in Newcastle upon Tyne (Newcastle and North Tyneside Drug and Alcohol Service, Plummer Court). A total of 145 direct-access admissions to the Smithfield Centre and 77 admissions to Plummer Court completed a battery of questionnaires shortly after intake and were followed up 6 months after discharge. Full economic data at follow-up were available for 54 Smithfield admissions and 49 Plummer Court admissions. Mean total cost of treatment per patient was pound1113 at the Smithfield Centre and pound1054 at Plummer Court in 2003-04 prices. Comparing the 6 months before treatment with the 6 months before follow-up, social costs fell by pound331 on average for each patient at Plummer Court but rose by pound1047 for each patient at the Smithfield Centre. When treatment costs and wider social costs were combined, the total cost to society at Smithfield was on average pound2159 per patient whilst at Plummer Court it was pound723 per patient. Combining the cost of treatment with drinking outcomes yielded a net cost per unit reduction in alcohol consumption of pound1.79 at Smithfield and pound1.68 at Plummer Court. Both services delivered a flexible needs-based service to very disadvantaged population at a reasonable cost and were associated with statistically significant reductions in drinking. For some patients, there was evidence of public sector resource savings but for others these detoxification services allowed those not previously in contact with services to meet health and social care needs. These patterns of cost through time are more complex than in previous evaluations of less severely dependent patients and difficult to predict from drinking patterns or patient characteristics. More research is required to judge

Enzymatic Mercury Detoxification: The Regulatory Protein MerR

CERN Multimedia

Ctortecka, B; Walsh, C T; Comess, K M

2002-01-01

Mercury ions and organomercurial reagents are extremely toxic due to their affinity for thiol groups. Many bacteria contain an elaborate detoxification system for a metabolic conversion of toxic Hg$^{2+}$ or organomercurials to less toxic elemental Hg$^0$. The main components of the enzymatic mercury detoxification (see Fig. 1) are the regulatory protein MerR (mercury responsive genetic switch), the organomercurial lyase MerB (cleavage of carbon mercury bonds), and the mercuric ion reductase MerA (reduction of mercuric ions). In these proteins Hg$^{2+}$ is usually coordinated by the thiol groups of cysteines. We utilize the nuclear quadrupole interaction (NQI) of ${\\rm^{199m}}$Hg detected by time differential perturbed angular correlation (TDPAC) to identify the Hg metal site geometries in these proteins in order to elucidate the molecular origin of the ultrasensitivity, selectivity and reaction mechanism of this detoxification system. The short lived TDPAC probe ${\\rm^{199m}}$Hg ($\\tau_{1/2} =$ 43 min) is su...

Individuals with substance use disorders are more likely to have antisocial and borderline personality disorder than non-substance abusers. Recently, research has examined the relations between early maladaptive schemas and personality disorders, as early maladaptive schemas are believed to underlie personality disorders. However, there is a dearth of research on the relations between early maladaptive schemas and personality disorders among individuals seeking treatment for substance abuse. The current study examined the relations among early maladaptive schemas and antisocial and borderline personality within in a sample of men seeking substance abuse treatment (n = 98). Results demonstrated that early maladaptive schema domains were associated with antisocial and borderline personality symptoms. Implications of these findings for substance use treatment and research are discussed. Antisocial (ASPD) and Borderline (BPD) personality disorder symptoms are prevalence among individuals seeking substance abuse treatment. Early maladaptive schemas are believed to underlie the development of ASPD and BPD symptoms, and are also prevalence among individuals seeking substance use treatment. Findings from the current study suggest that specific early maladaptive schema domains predict ASPD and BPD symptoms in a substance abuse treatment seeking sample of adult males. The treatment of ASPD and BPD among men seeking substance use treatment may want to focus on early maladaptive schemas. Copyright © 2013 John Wiley & Sons, Ltd.

Full Text Available Abstract Background Early recognition of the signs and symptoms of mental health disorders is important because early intervention is critical to restoring the mental as well as the physical and the social health of an individual. This study sought to investigate patterns of treatment seeking behavior and associated factors for mental illness. Methods A quantitative, institution-based cross sectional study was conducted among 384 psychiatric patients at Jimma University Specialized Hospital (JUSH located in Jimma, Ethiopia from March to April 2010. Data was collected using a pretested WHO encounter format by trained psychiatric nurses. Data was analyzed using SPSS V.16. Result Major depression disorder 186 (48.4%, schizophrenia 55 (14.3% and other psychotic disorders 47 (12.2% were the most common diagnoses given to the respondents. The median duration of symptoms of mental illness before contact to modern mental health service was 52.1 weeks. The main sources of information for the help sought by the patients were found to be family 126 (32.8% and other patients 75 (19.5%. Over a third of the patients 135 (35.2%, came directly to JUSH. Half of the patients sought traditional treatment from either a religious healer 116 (30.2% or an herbalist 77 (20.1% before they came to the hospital. The most common explanations given for the cause of the mental illness were spiritual possession 198 (51.6% and evil eye 61 (15.9%, whereas 73 (19.0% of the respondents said they did not know the cause of mental illnesses. Nearly all of the respondents 379 (98.7% believed that mental illness can be cured with modern treatment. Individuals who presented with abdominal pain and headache were more likely to seek care earlier. Being in the age group 31-40 years had significant statistical association with delayed treatment seeking behavior. Conclusions There is significant delay in modern psychiatric treatment seeking in the majority of the cases. Traditional healers

In cocaine-dependent patients, gray matter (GM) volume reductions have been observed in the frontal lobes that are associated with the duration of cocaine use. Studies are mostly restricted to treatment-seekers and studies in non-treatment-seeking cocaine abusers are sparse. Here, we assessed GM volume differences between 30 non-treatment-seeking cocaine-dependent individuals and 33 non-drug using controls using voxel-based morphometry. Additionally, within the group of non-treatment-seeking cocaine-dependent individuals, we explored the role of frequently co-occurring features such as trait impulsivity (Barratt Impulsivity Scale, BIS), smoking, and depressive symptoms (Beck Depression Inventory), as well as the role of cocaine use duration, on frontal GM volume. Smaller GM volumes in non-treatment-seeking cocaine-dependent individuals were observed in the left middle frontal gyrus. Moreover, within the group of cocaine users, trait impulsivity was associated with reduced GM volume in the right orbitofrontal cortex, the left precentral gyrus, and the right superior frontal gyrus, whereas no effect of smoking severity, depressive symptoms, or duration of cocaine use was observed on regional GM volumes. Our data show an important association between trait impulsivity and frontal GM volumes in cocaine-dependent individuals. In contrast to previous studies with treatment-seeking cocaine-dependent patients, no significant effects of smoking severity, depressive symptoms, or duration of cocaine use on frontal GM volume were observed. Reduced frontal GM volumes in non-treatment-seeking cocaine-dependent subjects are associated with trait impulsivity and are not associated with co-occurring nicotine dependence or depression.

Despite previous evidence supporting the use of the Cigarette Purchase Task (CPT) as a valid tool for assessing smoking reinforcement, research assessing how environmental changes affect CPT performance is scarce. This study addressed for the first time the differential effect of treatment condition [Cognitive Behavioral Treatment (CBT) + Behavioral Activation (BA) versus CBT + BA + Contingency Management (CM)] on cigarette demand among treatment seeking smokers with depressive symptoms. It also sought to assess whether reductions in smoking consumption arranged over the course of an intervention for smoking cessation impact on in-treatment cigarette demand. Participants were 92 smokers with depressive symptoms from a randomized clinical trial that received eight weeks of either CBT + BA or CBT + BA + CM. Individuals completed the CPT 8 times; the first during the intake visit and the remaining 7 scheduled once a week in midweek sessions. Cotinine samples were collected in each session. Participants receiving CBT + BA + CM showed higher reduction in cigarette demand across sessions than participants receiving CBT + BA, although this comparison was only significant for the intensity index (p = .004). Cotinine was positively related to cigarette demand (all p values demand reductions (all p values demand. Copyright © 2018 Elsevier Ltd. All rights reserved.

Provision of alternative non-drug reinforcement is among the most effective methods for treating substance use disorders. However, when alternative reinforcers become unavailable during treatment interruptions or upon cessation of treatment, relapse often occurs. Relapse following the loss of alternative reinforcement is known as resurgence. One factor that could reduce resurgence is longer duration of treatment with alternative reinforcement, but the available data are mixed. Further, the effects of length of treatment have previously only been examined with food seeking. The present experiments directly examined if duration of treatment impacted the magnitude of resurgence of cocaine or alcohol seeking in rats. First, rats were trained to self-administer cocaine (Experiment 1) or alcohol (Experiment 2) by performing a target behavior. Second, target behavior was extinguished and performing an alternative behavior produced an alternative non-drug (i.e., food) reinforcer. Finally, resurgence was assessed following removal of alternative reinforcement after either 5 or 20 sessions of treatment. Treatment duration did not differentially affect resurgence of cocaine seeking in Experiment 1 or Alcohol seeking in Experiment 2. These results suggest that extended treatment with alternative non-drug reinforcement may not decrease propensity to relapse. Further, these results may have implications for treatment of substance use disorders and for theories of resurgence. Copyright © 2017 Elsevier B.V. All rights reserved.

Recent research has begun to examine the early maladaptive schemas of substance abusers, as it is believed that targeting these core beliefs in treatment may result in improved substance use outcomes. One special population that has received scant attention in the research literature, despite high levels of substance use, is airline pilots. The current study examined the early maladaptive schemas of a sample of airline pilots ( n = 64) who were seeking residential treatment for alcohol dependence and whether they differed in early maladaptive schemas from non-pilot substance abusers who were also seeking residential treatment for alcohol dependence ( n = 45). Pre-existing medical records from patients of a residential substance abuse treatment facility were reviewed for the current study. Of the 18 early maladaptive schemas, results demonstrated that pilots scored higher than non-pilots on the early maladaptive schema of unrelenting standards (high internalized standards of behavior), whereas non-pilots scored higher on insufficient self-control (low frustration tolerance and self-control). Early maladaptive schemas may be a relevant treatment target for substance abuse treatment seeking pilots and non-pilots.

Dissociative experiences are common in traumatized individuals, and can sometimes be mistaken for psychosis. It is difficult to identify pathological dissociation in the treatment of traumatized refugees, because there is a lack of systematic clinical descriptions of dissociative phenomena in refugees. Furthermore, we are currently unaware of how dissociation measures perform in this clinical group. To describe the phenomenology of dissociative symptoms in Bosnian treatment-seeking refugees in Denmark. As a part of a larger study, dissociation was assessed systematically in 86 Bosnian treatment-seeking refugees using a semi-structured clinical interview (Structured Interview for Disorders of Extreme Stress-dissociation subscale; SIDES-D) and a self-report scale (Dissociative Experiences Scale; DES). The SIDES-D indicated twice as high prevalence of pathological dissociation as the DES. According to the DES, 30% of the refugees had pathological dissociation 15 years after their resettlement. On the SIDES-D, depersonalization and derealization experiences were the most common. Also, questions about depersonalization and derealization at times elicited reporting of visual and perceptual hallucinations, which were unrelated to traumatic re-experiencing. Questions about personality alteration elicited spontaneous reports of a phenomenon of "split" pre- and post-war identity in the refugee group. Whether this in fact is a dissociative phenomenon, characteristic of severe traumatization in adulthood, needs further examination. Knowledge of dissociative symptoms in traumatized refugees is important in clinical settings to prevent misclassification and to better target psychotherapeutic interventions. Much development in the measurement of dissociation in refugees is needed.

Many gambling-specific CBT programs seek to target either gambling-related urge or cognitions or both. However, little is known of the influence of one symptom type on another across time and whether these differ for men and women help-seeking problem gamblers. The aim of this study was threefold: to determine presence of measurement invariance for urge and cognition measures over time; to investigate the effect of baseline urge on end-of-treatment gambling-related cognitions - and the reciprocal relationship; and, identify whether these pathways differ across gender. Self-reported gambling urge (GUS), and gambling-related cognitions (GRCS) data from treatment-seeking problem gamblers prior to and post treatment (N = 223; 62% men) were analyzed with cross-lagged panel models, moderated by gender. Conceptualization of urge and cognitions were found to be temporally stable. There was no significant association between baseline GUS scores and post-treatment GRCS scores, nor the reverse relationship. Putatively, this infers that coexisting urge and gambling-related cognition components of problem gambling operate independently over time. Analyses revealed gambling urge had a significantly stronger tracking correlation across time for men than women when adjusting for cognition paths. This investigation provides early evidence for tailoring CBT in response to sub-population gambling-related characteristics, demonstrated across men and women. Copyright © 2018 Elsevier B.V.

The treatment of sexual dysfunction in patients with prior sexual offenses poses ethical and legal dilemmas. Sex offenders are not obligated by law to disclose this history to medical professionals. Over 20% of sex offenders experience sexual dysfunction; however, the number of sex offenders seeking evaluation for sexual dysfunction is unknown. The aims of this study were to determine the incidence and characteristics of sex offenders seeking treatment in our clinic; and to review data regarding sex offender recidivism and ethics pertaining to the issue as it relates to treating physicians. Sex offenders were identified via three methods: new patient screening in a dedicated sexual medicine clinic, chart review of those on intracavernosal injection (ICI) therapy for erectile dysfunction (ED), and review of patient's status-post placement of penile prosthesis. Charts were cross-referenced with the U.S. Department of Justice National Sex Offender Public Website. Patient characteristics and details of offenses were collected. The main outcome measures used were a self-reported sexual offense and national registry data. Eighteen male sex offenders were identified: 13 via new patient screening; 3 by review of ICI patients; 1 by review of penile prosthesis data; and 1 prior to penile prosthesis placement. All were primarily referred for ED. Of those with known offenses, 64% were level 3 offenders (most likely to re-offend). The same number had committed crimes against children. All those with complete data had multiple counts of misconduct (average 3.6). Ninety-four percent (17/18) had publicly funded health care. Twelve (67%) were previously treated for sexual dysfunction. Registered sex offenders are seeking and receiving treatment for sexual dysfunction. It is unknown whether treatment of sexual dysfunction increases the risk of recidivism of sexual offenses. Physicians currently face a difficult choice in deciding whether to treat sexual dysfunction in sex

Male sexual dysfunction is a significant international public health issue affecting both middle-aged and older adults. To date, however, no studies have compared age differences in psychiatric issues, frequency of sexual activity and treatment recommendations between older and middle-aged male military Veterans seeking treatment for erectile dysfunction (ED) in the U.S.A. Data were collected between 1982 and 2003 at the Palo Alto Veterans Affairs Andrology Clinic. The 1,250 participants, aged 22 to 87 years (median = 63), completed a semi-structured interview. Using multiple linear regressions, we examined age differences in five domains: medical and endocrine risk factors; psychiatric and psychosocial risk factors; frequency of sexual behaviors; self-reported and objectively measured erectile function; and treatment recommendations. Compared with middle-aged adults, older adults were more likely to present for ED treatment with medical risk factors and were more often recommended a vacuum pump treatment. Middle-aged male Veterans were more likely to experience psychiatric risk factors for ED and were more sexually active than older Veterans. Despite greater objective erectile ability in middle-aged adults, there were no age differences in maximum self-reported erectile functioning. These results provide some evidence of age-related characteristics and treatment needs of male patients seeking treatment for sexual dysfunction. We encourage health care professionals working with adults across the lifespan to consider ways to individualize psychoeducation and brief psychotherapy for the treatment of ED to the specific needs of the patient, which may vary between middle-aged and older cohorts of patients.

2010-01-01

Objective We sought to examine rates of eating disorder symptoms among seriously overweight children seeking treatment using the Eating Disorder Examination for Children (ChEDE) and to provide initial data about their association with treatment outcome. Method Overweight children (N = 27) 8–13 years old were interviewed using the ChEDE before participating in a family-based behavioral treatment program. Height and weight were measured pretreatment, posttreatment, and approximately 8 months posttreatment. Results Fifteen percent of children reported subjective bulimic episodes (SBE). Weight loss did not differ for children with and without SBEs, but concerns about body shape were related to larger weight losses during treatment. Conclusion A considerable minority of treatment-seeking overweight children report an episodic sense of loss of control over eating. Loss of control is related to other disordered eating attitudes and behaviors, but does not appear to affect treatment outcome. Future studies are needed to replicate these initial findings.

Alcohol use disorders are among the mental disorders with the lowest treatment rates. Increasing the treatment rates requires insight on the reasons why patients do not seek treatment. This study examined self-reported reasons for not seeking treatment and their association with alcohol use disorder severity among primary health care patients diagnosed with an alcohol use disorder. Alcohol use disorders, health service utilization, and reasons for not seeking treatment were assessed via interviews on regionally representative samples of primary care patients from 6 European countries (Italy, Germany, Hungary, Latvia, Poland and Spain, total N = 9,098). Additionally, general practitioners had to fill in a questionnaire assessing their patients' alcohol use and alcohol use disorders. A multinomial logistic regression was performed to investigate the association between reasons for not seeking treatment and alcohol use disorder severity. Of 1,008 patients diagnosed with an alcohol use disorder (via general practitioner or patient interview) in the past 12 months, the majority (N = 810) did not receive treatment and 251 of those gave a reason for not seeking treatment. The most frequent reason was 'lack of problem awareness' (55.3% of those who responded), the second most common response was 'stigma or shame' (28.6%), followed by 'encounter barriers' (22.8%) and 'cope alone' (20.9%). The results indicated lower probabilities of reporting 'denial' and higher probabilities to report 'encounter barriers' as alcohol use disorders severity increases. However, both trends were discontinued for patients with severe alcohol use disorders. Particularly at lower levels of alcohol use disorder severity, a lack of problem awareness prevents patients from seeking treatment. Routinely alcohol consumption monitoring in primary care practices could help primary and secondary prevention of alcohol use disorders and increase treatment coverage.

Whitsett, David; Sherman, Martin F

2017-12-01

Mental health clinicians who work with asylum seekers provide services to patients who face stressful everyday living conditions. However, little is known about how these problems potentially impact psychiatric treatment within these populations. The purpose of this study was thus to examine whether resettlement factors predict outcomes of a mental health intervention for a sample of asylum-seeking survivors of torture. The study included data from a US outpatient clinic that specialized in treating asylum-seeking survivors of torture. Patients (primarily from Iraq, Afghanistan and African Countries) were evaluated on demographic factors at intake and psychiatric symptoms throughout the course of treatment. Patients experienced significant reductions in depression, anxiety and trauma symptoms, although symptoms still remained near or above clinical thresholds. Stable, uncrowded housing conditions significantly predicted lower depression, anxiety and trauma symptoms at follow-up. These findings support the hypotheses that individuals seeking asylum within the United States who have survived torture can benefit from psychiatric treatment and emphasize the importance of stable living conditions in improving treatment effectiveness. This suggests the need for further research on social predictors of treatment outcomes, as well as the need for clinicians and policymakers to target improved housing as a potentially important tool to reduce psychiatric problems related to torture and forced migration.

Brown, Nicholas B; Bruce, Steven E

Mental health related stigma, as well as mental illness symptomatology, have been shown to negatively impact treatment-seeking within military populations. However, few studies have delineated the 2 forms of stigma (self-stigma and public stigma), and none have differentiated between stigma and career-related consequences (career worry). The aim of this study was to increase our understanding of low treatment-seeking rates among soldiers and veterans by expanding upon previous measurements of the stigma construct and examining factors influencing willingness to seek treatment. The sample consisted of 276 Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) soldiers and veterans. Individual levels of self-stigma, public stigma, and career worry were measured, as were levels of willingness to seek treatment. Symptoms of PTSD, depression, and substance abuse were also evaluated to account for the influence of mental illness on treatment-seeking. A confirmatory factor analysis indicated that a 3-factor model including self-stigma, public stigma, and career worry fit the data significantly better than a 1- or 2- factor model. A multiple regression analysis also revealed that these 3 factors, combined with mental illness symptomatology, significantly predicted individual levels of willingness to seek treatment. Career worry was the strongest predictor, particularly for individuals with no treatment history. This study confirmed that career worry is a factor independent of self-stigma and public stigma. Findings indicate that a fear of negatively affecting one's career is the most influential factor in determining willingness to seek mental health treatment for the military population.

Binge eating has a complex etiology and is likely influenced by a wide range of biological, psychological, social, and environmental factors. Among the environmental and behavioral contributors, television use has been strongly linked to obesity and unhealthy eating behaviors. The current study tested whether television use predicts binge eating symptomatology in adults seeking behavioral weight loss treatment. Participants (N=116) were adults seeking weight loss treatment in group-based behavioral weight loss programs. Average body mass index was 38.5; average age was 45.3. They completed measures of binge eating symptomatology, television use, internalized weight stigma, depression, body satisfaction, and habitual physical activity. The amount of television participants watched per week was associated with binge eating symptomatology even after controlling for relevant covariates. Binge eating symptomatology was positively associated with television use, internalized weight stigma, depression, and decreased body satisfaction. The findings of the current study support the hypothesis that television use is a significant predictor of binge eating symptomatology for adults attempting weight loss. Determining the causal nature of the relationship and whether binge eating is occurring during television viewing will be important areas of future inquiry. © 2013.

Thiabendazole (TBZ) is a persistent fungicide used in the post-harvest treatment of fruits. Its application results in the production of contaminated effluents which should be treated before their environmental discharge. In the absence of efficient treatment methods in place, biological systems based on microbial inocula with specialized degrading capacities against TBZ could be a feasible treatment approach. Only recently the first bacterial consortium able to rapidly transform TBZ was isolated. This study aimed to characterize its biodegradation, bioremediation and detoxification potential. The capacity of the consortium to mineralize 14 C-benzyl-ring labelled TBZ was initially assessed. Subsequent tests evaluated its degradation capacity under various conditions (range of pH, temperatures and TBZ concentration levels) and relevant practical scenarios (simultaneous presence of other postharvest compounds) and its bioaugmentation potential in soils contaminated with increasing TBZ levels. Finally cytotoxicity assays explored its detoxification potential. The consortium effectively mineralized the benzoyl ring of the benzimidazole moiety of TBZ and degraded spillage level concentrations of the fungicide in aqueous cultures (750 mg L -1 ) and in soil (500 mg kg -1 ). It maintained its high degradation capacity in a wide range of pH (4.5-7.5) and temperatures (15-37 °C) and in the presence of other pesticides (ortho-phenylphenol and diphenylamine). Toxicity assays using the human liver cancer cell line HepG2 showed a progressive decrease in cytotoxicity, concomitantly with the biodegradation of TBZ, pointing to a detoxification process. Overall, the bacterial consortium showed high potential for future implementation in bioremediation and biodepuration applications.

Full Text Available Aims. This prospective study aims to identify patient characteristics as predictors for treatment outcome during inpatient detoxification treatment for drug and alcohol dependent patients. Methods. A mixed gender sample of 832 consecutively admitted drug and alcohol dependent patients were interviewed by an experienced physician. The impact of a variety of factors concerning social environment, therapy motivation, impulsivity related variables, medical history, and addiction severity on treatment outcome was examined. Results. 525 (63.1% of the patients completed detoxification treatment whereas 307 (36.9% dropped out prematurely. Being female, living in a partnership, having children, being employed, and having good education were predictive for a positive outcome. Family, health, the fear of losing the job, prosecution, and emergency admission were significant motivational predictors for treatment outcome. Being younger, history of imprisonment, and the number of previous drop-outs were predictive for a negative outcome. Conclusions. Variables concerning social environment and the number of previous drop-outs have been identified as best predictors for treatment outcome. Socially stable patients benefit from the current treatment setting and treatment shall be adapted for patients with negative predictors. Treatment may consequently be tailored with respect to intervention type, duration, and intensity to improve the outcome for those patients that fulfil criteria with negative impact on treatment retention.

Classifying eating disorders in youth is challenging in light of developmental considerations and high rates of diagnostic migration. Understanding the transactional relationships among eating disorder symptoms, both across the transdiagnostic spectrum and within specific diagnostic categories, may clarify which core eating disorder symptoms contribute to, and maintain, eating-related psychopathology in youth. We utilized network analysis to investigate interrelationships among eating disorder symptoms in 636 treatment-seeking children and adolescents (90.3% female) ages 6-18 years (M age = 15.4 ± 2.2). An undirected, weighted network of eating disorder symptoms was created using behavioral and attitudinal items from the Eating Disorder Examination. Across diagnostic groups, symptoms reflecting appearance-related concerns (e.g., dissatisfaction with shape and weight) and dietary restraint (e.g., a desire to have an empty stomach) were most strongly associated with other eating disorder symptoms in the network. Binge eating and compensatory behaviors (e.g., self-induced vomiting) were strongly connected to one another but not to other symptoms in the network. Network connectivity was similar across anorexia nervosa, bulimia nervosa, and otherwise specified feeding or eating disorder subgroups. Among treatment-seeking children and adolescents, dietary restraint and shape- and weight-related concerns appear to play key roles in the psychopathology of eating disorders, supporting cognitive-behavioral theories of onset and maintenance. Similarities across diagnostic categories provide support for a transdiagnostic classification scheme. Clinical interventions should seek to disrupt these symptoms early in treatment to achieve maximal outcomes. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Despite the chronic and relapsing nature of inflammatory bowel diseases (IBD), at least 30% to 45% of the patients are noncompliant to treatment. IBD patients often seek information about their disease. To examine the association between information-seeking activity and treatment compliance among IBD patients. To compare information sources and concerns between compliant and noncompliant patients. We used data from the Swiss IBD cohort study, and from a qualitative survey conducted to assess information sources and concerns. Crude and adjusted odds ratios (OR) for noncompliance were calculated. Differences in the proportions of information sources and concerns were compared between compliant and noncompliant patients. A total of 512 patients were included. About 18% (n = 99) of patients were reported to be noncompliant to drug treatment and two-thirds (n = 353) were information seekers. The OR for noncompliance among information seekers was 2.44 (95%CI: 1.34-4.41) after adjustment for confounders and major risk factors. General practitioners were 15.2% more often consulted (p = 0.019) among compliant patients, as were books and television (+13.1%; p = 0.048), whereas no difference in proportions was observed for sources such as internet or gastroenterologists. Information on tips for disease management were 14.2% more often sought among noncompliant patients (p = 0.028). No difference was observed for concerns on research and development on IBD or therapies. In Switzerland, IBD patients noncompliant to treatment were more often seeking disease-related information than compliant patients. Daily management of symptoms and disease seemed to be an important concern of those patients.

Is arsenic biotransformation a detoxification mechanism for microorganisms?

International Nuclear Information System (INIS)

Rahman, M. Azizur; Hassler, Christel

2014-01-01

Arsenic (As) is extremely toxic to living organisms at high concentration. In aquatic systems, As exists in different chemical forms. The two major inorganic As (iAs) species are As V , which is thermodynamically stable in oxic waters, and As III , which is predominant in anoxic conditions. Photosynthetic microorganisms (e.g., phytoplankton and cyanobacteria) take up As V , biotransform it to As III , then biomethylate it to methylarsenic (MetAs) forms. Although As III is more toxic than As V , As III is much more easily excreted from the cells than As V . Therefore, majority of researchers consider the reduction of As V to As III as a detoxification process. The biomethylation process results in the conversion of toxic iAs to the less toxic pentavalent MetAs forms (monomethylarsonate; MMA V , dimethylarsonate; DMA V , and trimethylarsenic oxide; TMAO V ) and trimethylarsine (TMAO III ). However, biomethylation by microorganisms also produces monomethylarsenite (MMA III ) and dimethylarsenite (DMA III ), which are more toxic than iAs, as a result of biomethylation by the microorganisms, demonstrates the need to reconsider to what extent As biomethylation contributes to a detoxification process. In this review, we focused on the discussion of whether the biotransformation of As species in microorganisms is really a detoxification process with recent data

Can Chlorella pyrenoidosa be a bioindicator for hazardous solid waste detoxification?

Four kinds of solid waste residue (SWR, S1 to S4) from different stages in a sequential detoxification process were chosen. The biotoxicity of the leachates from S1 to S4 was tested by Chlorella pyrenoidosa. The growth inhibition, the chlorophyll a (chla) and chlorophyll b (chlb) concentrations, and the ultrastructural morphology of cells of C. pyrenoidosa were studied. It shows that the growth inhibition of C. pyrenoidosa significantly increased with increasing leachate concentration when exposed to the leachates from S1, S2, S3, and S4, respectively. It well reflects the toxicity difference of leachate from SWR at different treatment stages, namely S1 > S2 > S3 > S4. Correspondingly, the chla and chlb concentrations of C. pyrenoidosa increased gradually as SWR was treated deeply. Leachate disrupted chlorophyll synthesis and inhibited cell growth. The changing of the ultrastructural morphology of cells under different leachate exposures, such as volume of chloroplasts and quantity of thylakoids reducing, confirmed the toxicity decrease of leachates from different stages. C. pyrenoidosa is a good bioindicator for hazardous solid waste detoxification. The EC{sub 50} at difference scenarios also suggests that it was feasible to estimate ecological toxicity of leachates to C. pyrenoidosa after exposure times of 72 h. C. pyrenoidosa can be introduced to evaluate the effect of hazardous solid waste disposal by biotoxicity assessment. - Highlights: Black-Right-Pointing-Pointer The detoxification process of hazardous solid waste was evaluated by Chlorella pyrenoidosa. Black-Right-Pointing-Pointer The best exposure time of ecological toxicity assessment of Chlorella pyrenoidosa was presented. Black-Right-Pointing-Pointer The possible toxicity of the hazardous solid waste at different disposal stage on Chlorella pyrenoidosa was explored from cell tissue.

Gender differences in pathological gambling disorder (PGD) have received little investigation. This study was constructed to detail the demographic and phenomenological differences in men and women with PGD. We assessed gender differences in 131 subjects with PGD who were evaluated in terms of demographic characteristics, clinical features of PGD, and treatment history. Seventy-eight (60%) subjects were women, and 53 (40%) were men. Men had an earlier age of onset of gambling behavior, while women progressed to pathological gambling sooner after beginning to gamble. In terms of gambling behavior, men were more likely to engage in blackjack, cards, sporting events, and the track, whereas women played slot machines and bingo. Women reported that loneliness was the major trigger to gambling, while men were more likely to gamble secondary to sensory stimuli. Although men were as likely as women to have filed bankruptcy because of gambling, women were more likely to have written bad checks and men were more likely to have lost significant savings. Both groups were equally likely to seek treatment, but Gamblers Anonymous (GA) and outpatient therapy were reported equally ineffective in reducing gambling symptoms. There appear to be some gender differences in the clinical features of PGD, and these differences may have treatment implications. Copyright 2002 by W.B. Saunders Company

Several different pesticides (alachlor, atrazine, chlorfenvinphos, diuron, isoproturon and pentachlorophenol) considered PS (priority substances) by the European Commission and dissolved in water at 50mg/L (or at maximum water solubility) have been degraded at pilot-plant scale using photo-Fenton and TiO{sub 2} photocatalysis driven by solar energy. Two different iron concentrations (2 and 55mg/L) and TiO{sub 2} at 200mg/L have been tested and discussed, using mainly TOC mineralisation for comparison of treatment effectiveness. Vibrio fischeri (Microtox{sup (}R)) toxicity assays were also employed for evaluating the photocatalytic treatments, and comparison between these results and parent compound disappearance, TOC evolution and anion (or ammonia) release were discussed. Almost complete mineralisation and total detoxification were always attained. It has been demonstrated that evolution of chloride could be a key-parameter for predicting toxicity of chlorinated compounds.

Despite the high prevalence of intimate partner violence (IPV) perpetration by men receiving substance use treatment, little is known about their help-seeking behaviors for IPV. A secondary analysis of a mixed-methods study of men receiving substance use treatment who perpetrated IPV examined the prevalence, characteristics, and barriers associated with IPV perpetration disclosure and help-seeking. In total, 170 men were interviewed using a structured questionnaire, and a subsample of 20 were interviewed in-depth about their experiences. Logistic regression determined variables associated with disclosure and help-seeking. Thematic analysis of the in-depth interviews explored barriers to disclosure and help-seeking. Only half the participants had told anyone about their IPV perpetration and about one quarter reported having sought any sort of support. Whereas participants were more likely to disclose their IPV perpetration to informal resources (such as friends or family), they tended to seek help from formal resources (such as health professionals or the police). A greater proportion of physical IPV perpetrators, who had disclosed, had been arrested or had police involvement for IPV, suggesting that their disclosure may not have been voluntary. The following themes emerged from the qualitative data about the barriers to disclosure and help-seeking for IPV perpetration: fear that their children would be taken into care by social services, shame and embarrassment, and a minimization or normalization of their behavior. In addition, many participants highlighted that they had never been previously asked about IPV during treatment for substance use and stressed the need for greater expertise in or knowledge of this topic from specialist services. Substance use treatment services should enquire about men's relationships and IPV perpetration to facilitate disclosure and provide support. Further research is necessary to determine the context of disclosure and help-seeking

Construction sites are potential breeding places for some species of mosquitoes. Construction workers usually stay at the construction sites, thus being extremely susceptible to malaria. For malaria control, a special focus on them is warranted as they often seek treatment from unregulated, private vendors, increasing their risk of exposure to substandard drugs. To elicit the socio-demographic factors associated with comprehensive malaria knowledge (symptoms, mode of spread, and preventive measures) and treatment-seeking pattern (preferred source and type of treatment) among the construction workers in Mangaluru, India; and, to study the association among their comprehensive malaria knowledge, past suffering from malaria (within 1 year) and treatment-seeking pattern. A community based cross-sectional study was conducted in nine randomly selected construction sites of Mangaluru, a high-risk city for malaria with an annual parasite incidence of >2/1000/year, from June-September 2012. A sample size of 132 was estimated assuming at least 30% of them have satisfactory malaria knowledge, 10% absolute precision, 95% confidence level, design effect of 1.5 and 10% non-responses. A semi-structured interview schedule was used, and knowledge scores were computed. Multivariate linear (for knowledge score) and logistic regressions (for preferred source and type of treatment) were applied. One hundred and nineteen workers participated in the study (total approached-138). 85% (n = 101) of them were males. Mean knowledge score was 9.95 ± 3.19 (maximum possible score-16). The majority of them were aware of the symptoms and the mode of malaria transmission. However, workers (β = -0.281, p = 0.001), self stated malaria within 1 year (β = 0.276, p workers (AdjOR 7.21, 95% CI 2.3-22.9) and those with self stated malaria within 1 year (AdjOR 11.21, 95% CI 2.38-52.8) showed favorable treatment-seeking pattern. There is an urgent need of intensifying and streamlining of ongoing malaria

Natural recovery and treatment-seeking in pathological gambling: results of two U.S. national surveys.

Pathological gambling is described in DSM-IV as a chronic and persisting disorder, but recent community-based longitudinal studies that have highlighted the transitory nature of gambling-related problems have called into question whether this is an accurate characterization. This emerging evidence of high rates of recovery coupled with low rates of treatment-seeking for pathological gambling suggests that natural recovery might be common. The purpose of the present study was to document the rates of recovery, treatment-seeking, and natural recovery among individuals with DSM-IV pathological gambling disorder in two large and representative U.S. national surveys. Prevalences of recovery, treatment-seeking, and natural recovery were estimated among individuals from the Gambling Impact and Behavior Study (N=2,417) and the National Epidemiologic Survey on Alcohol and Related Conditions (N=43,093) who reported a lifetime history of DSM-IV pathological gambling disorder (N=21 and N=185, respectively). Among individuals with a lifetime history of DSM-IV pathological gambling, 36%-39% did not experience any gambling-related problems in the past year, even though only 7%-12% had ever sought either formal treatment or attended meetings of Gamblers Anonymous. About one-third of the individuals with pathological gambling disorder in these two nationally representative U.S. samples were characterized by natural recovery. Pathological gambling may not always follow a chronic and persisting course. A substantial portion of individuals with a history of pathological gambling eventually recover, most without formal treatment. The results of large epidemiological surveys of pathological gambling may eventually overturn the established wisdom about pathological gambling disorder.

In the present study, the effect of previous detoxifications on prefrontal function and decision making was examined in alcohol-dependent patients. Further, we examined whether the length of abstinence affects cognitive function. Forty-eight alcohol-dependent patients were recruited from an inpatient detoxification treatment facility and cognitive function was compared to a control group of 36 healthy controls. The patient population was then divided into a group of patients with less than two previous detoxifications (LO-detox group, n = 27) and a group of patients with two or more previous detoxifications (HI-detox group, n = 21) and cognitive function was compared. In addition, cognitive function of recently (i.e. less than 16 days; median split) and longer abstinent patients was compared. We assessed prefrontal function, memory function and intelligence. Alcoholics, when compared to healthy controls, performed worse with regard to the performance index Attention/Executive function. Cognitive impairment in these tasks was pronounced in recently abstinent patients. We found no significant differences between HI-detox and LO-detox patients with regard to the Attention/Executive function. However, in the IOWA gambling Task, the HI-detox group seemed to be less able to learn to choose cards from the more advantageous decks over time. Our results provide additional evidence for cognitive impairment of alcohol-dependent patients with regard to tasks sensitive to frontal lobe function and underline the importance of abstinence for these impairments to recover. We found only little evidence for the impairing effects of repeated withdrawal on prefrontal function and we suggest that executive function is affected earlier in dependence.

A Web-based survey examined treatment seeking among community college students to inform the design of engagement interventions. Veteran and civilian community college students (N=765) were screened for mental disorders and reported perceptions of treatment need, effectiveness, and stigma, as well as service use. Regression analysis identified predictors of pharmacotherapy and psychotherapy use. Of the 511 students who screened positive for a current mental disorder or reported a perceived need for treatment (149 veterans and 362 civilians), 30% reported past-year use of psychotropic medications. Predictors were perceived treatment need (odds ratio [OR]=7.81, p<.001) and the perception that psychotropic medications are effective (OR=3.38, p=.012). Eleven percent of participants reported past-year psychotherapy use, and predictors were a positive screen for posttraumatic stress disorder (OR=2.78, p=.04) and poorer financial status. Modifiable barriers, including perceived need for and effectiveness of treatment, were correlated with pharmacotherapy use and should be targeted by engagement interventions.

The toxicity of furfural residues (FRs) hydrolysate is a major obstacle in its application. This work focused on the detoxification of FRs hydrolysate and its application in butanol fermentation. Combination of activated carbon and resin 717 was appropriate for the detoxification of hydrolysate. Mixed sterilization of FRs hydrolysate and corn steep liquor (CSL) was better than the separate ones, since proteins in CSL could adsorb and remove toxic components during sterilization. The results further confirmed that simultaneous sterilization of activated carbon + resin and fermentation medium was more efficient for detoxification and butanol production, in which 76.4% of phenolic compounds and 99.3% of Maillard reaction products were removed, 8.48 g/L butanol and 12.61 g/L total solvent were obtained. This study provides feasible and economic approaches for the detoxification of FRs hydrolysate and its application in butanol production. Copyright © 2018 Elsevier Ltd. All rights reserved.

ABSTRACT OBJECTIVE To evaluate the clinical observation that the number of individuals seeking opioid detoxification from oxycodone was increasing at the Centre for Addiction and Mental Health (CAMH) in Toronto, Ont; and to identify the characteristics of individuals seeking opioid detoxification at CAMH. DESIGN Retrospective analysis of patient health records. SETTING Medical Withdrawal Management Service at CAMH. PARTICIPANTS All patients admitted for opioid detoxification between January 2000 and December 2004. MAIN OUTCOME MEASURES Number of opioid detoxification admissions each year; type, dose, and source of opioids; comorbid problems and symptoms. RESULTS There were 571 opioid detoxification admissions during the 5-year study period. The number of admissions increased steadily over the 5 years; in particular, the number of admissions related to controlled-release oxycodone increased substantially (3.8%, 8.3%, 20.8%, 30.6%, and 55.4% of the total opioid admissions in 2000 to 2004, respectively; χ42= 105.5, P < .001). The rates of admissions involving heroin remained low and stable. Use of controlled-release oxycodone was associated with considerably higher doses than use of other prescription opioids was. Physician prescriptions were the source of the prescription opioids for a large percentage of patients, particularly for older patients. Prescription opioid users reported considerable comorbid substance use problems, pain, and psychiatric symptoms. CONCLUSION This study has demonstrated a significant rise in the number of individuals seeking treatment at CAMH for controlled-release oxycodone addiction. The substantial comorbid pain, psychiatric symptoms, and other psychoactive substance use problems in these patients, coupled with the finding that prescriptions were an important source of opioids, highlight the clinical complexities encountered in the treatment of these individuals. Further research examining these complexities and the many possible

Full Text Available Background: The aim of this study was to compare the effectiveness of methadone detoxification with traditional method of gradual decrement in the abused amount of the refined opium dross (Shireh to control withdrawal syndrome in Shireh-addicted patients. Methods: In this study, two groups of Shireh addicts were compared. The first group was treated by methadone and the second group by gradual decrement in the amount of consumed Shireh. Those experiencing the adverse effects of the treatment were excluded from the study. Methadone dose was calculated based on the amount of the Shireh consumed and detoxification was performed during a 21-day period. In the second group, the amount of the consumed Shireh was gradually decreased within 21 days and some of the withdrawal symptoms were selected as indicators for patient evaluation. Results: A total of 35 patients (16 versus 19 patients in the first and second groups were evaluated. Their mean age was 43 ± 4 years and all were male. A statistically significant difference was found between these two groups in terms of severity and duration of withdrawal symptoms within the first five days and their duration after the 21st day of the onset of detoxification (P< 0.05. Conclusion: In comparison with methadone detoxification, traditional method of gradually decreasing the consumed amount of Shireh controls the severity and duration of withdrawal symptoms better in the course of detoxification.

Although ED can impair sexual satisfaction as well as the quality of partnership and life, men affected often avoid seeking treatment. There is growing evidence that women have an influence on their partner's help-seeking behavior. This qualitative study examined men with ED and their female partners in order to detect motivational factors for men to seek treatment and motivational actions of the women to support their partners. Twelve couples took part in a semi-structured telephone interview, which was performed separately in men and women. Analysis was on the basis of the Grounded Theory. The identified motivational factors could be divided into extrinsic (for example, media, female partner) and intrinsic (for example, desire to clarify the cause of the ED, hope for improvement) factors. Women can support their partners in treatment-seeking through various motivational actions such as talking with each other, showing interest and dealing actively with the problem, appealing to the male self-esteem, supporting the doctor's visit, forcing the treatment, active cooperation and participation in the treatment or initiating sexual intercourse. On the basis of these findings, recommendations for women were developed to support their partners and increase the probability of help-seeking behavior.

Rainbow trout (Oncorhynchus mykiss) subjected to three consecutive, alternating treatments with emamectin benzoate (EMB) and deltamethrin (DM) during outbreaks of Caligus rogercresseyi in a farm located in southern Chile (Hornopiren, Chiloé), were studied to determine the effects of these treatments on the protein and enzymatic activity levels of cytochrome P450 1A (CYP1A), flavin-containing monooxygenase (FMO) and glutathione S-transferase (GST) in different tissues. Consecutive and alternating EMB/DM treatments resulted in a 10-fold increase and 3-fold decrease of CYP1A protein levels in the intestine and gills, respectively. Notably, CYP1A activity levels decreased in most of the analyzed tissues. FMO protein and activity levels markedly increased in the kidney and the intestine. GST was up-regulated in all tissues, either as protein or enzyme activity. When comparing consecutive EMB/DM treatments against previous studies of EMB treatment alone, CYP1A activity levels were similarly diminished, except in muscle. Likewise, FMO activity levels were increased in most of the analyzed tissues, particularly in the muscle, kidney, and intestine. The increases observed for GST were essentially unchanged between consecutive EMB/DM and EMB only treatments. These results indicate that consecutive EMB/DM treatments in rainbow trout induce the expression and activity of FMO and GST enzymes and decrease CYP1A activity. These altered activities of detoxification enzymes could generate imbalances in metabolic processes, synthesis, degradation of hormones and complications associated with drug interactions. It is especially important when analyzing possible effects of consecutive antiparasitic treatments on withholding periods and salmon farming yields. Copyright © 2016 Elsevier Inc.

Arsenic (As) is extremely toxic to living organisms at high concentration. In aquatic systems, As exists in different chemical forms. The two major inorganic As (iAs) species are As{sup V}, which is thermodynamically stable in oxic waters, and As{sup III}, which is predominant in anoxic conditions. Photosynthetic microorganisms (e.g., phytoplankton and cyanobacteria) take up As{sup V}, biotransform it to As{sup III}, then biomethylate it to methylarsenic (MetAs) forms. Although As{sup III} is more toxic than As{sup V}, As{sup III} is much more easily excreted from the cells than As{sup V}. Therefore, majority of researchers consider the reduction of As{sup V} to As{sup III} as a detoxification process. The biomethylation process results in the conversion of toxic iAs to the less toxic pentavalent MetAs forms (monomethylarsonate; MMA{sup V}, dimethylarsonate; DMA{sup V}, and trimethylarsenic oxide; TMAO{sup V}) and trimethylarsine (TMAO{sup III}). However, biomethylation by microorganisms also produces monomethylarsenite (MMA{sup III}) and dimethylarsenite (DMA{sup III}), which are more toxic than iAs, as a result of biomethylation by the microorganisms, demonstrates the need to reconsider to what extent As biomethylation contributes to a detoxification process. In this review, we focused on the discussion of whether the biotransformation of As species in microorganisms is really a detoxification process with recent data.

This study examined racial/ethnic differences in demographic variables and the clinical presentation of treatment-seeking adults with binge eating disorder (BED) who participated in treatment research at a medical school-based program. Participants were 775 (n = 195 men, n = 560 women) treatment-seeking adults with DSM-IV-defined BED who self-identified as Black (n = 121), Hispanic (n = 54), or White (n = 580). Doctoral-level research clinicians assessed participants for BED and for eating disorder psychopathology using the Structured Clinical Interview for DSM-IV Disorders and the Eating Disorder Examination (EDE) interview, and measured height and weight. Participants also completed established self-report measures. Black participants had a greater proportion of women than White participants and White participants had higher education than Black and Hispanic participants. Black participants had higher body mass index (BMI) and reported more frequent binge eating episodes than White participants but eating-disorder psychopathology (EDE scales and Global Severity) did not significantly differ across racial/ethnic groups. Black participants had lower levels of depression than Hispanic and White participants. These differences in clinical presentation remained unchanged after adjusting for age, education, sex, and BMI. White participants had younger ages of onset for dieting, binge eating, and obesity, but not BED, than Black and Hispanic participants. There are some racial/ethnic differences in the developmental trajectories and clinical presentation of treatment-seeking adults with BED that remain unchanged after adjusting for demographic differences. Black participants presented for treatment with higher BMI and binge eating frequency than White participants and with lower depression than White and Hispanic groups, but associated eating disorder psychopathology levels were similar across racial/ethnic groups.

Objective. To assess the prevalence of complications related to osteopenia in the thoracic spine (anterior wedging and fish vertebrae) of patients admitted for substance abuse detoxification. Design and patients. We retrospectively identified 150 sequential patients admitted to our drug and alcohol detoxification ward in whom posteroanterior and lateral admission chest radiographs and clinical charts were available for review. There were 116 men and 34 women with a mean age of 37 years (range 19-67 years). Thirty-eight patients were admitted for drug detoxification, 37 for alcohol detoxification, and 75 for drug and alcohol detoxification. These patients were compared with 66 age- and sex-matched controls from our hospital's employee health service. Two radiologists reviewed all chest radiographs for the presence of anterior wedging and fish vertebrae in the thoracic spine and other nonspinal fractures. Serum calcium and inorganic phosphorus levels were recorded for the substance abuse detoxification patients. Results. Forty-nine percent (n=73) of detoxification patients had complications of osteopenia in the thoracic spine including: anterior wedging (n=47), fish vertebrae (n=21), or both (n=5). Twenty-four percent (n=36) of patients had an elevated serum inorganic phosphorus level and one patient had an elevated serum calcium level. Patients with anterior wedging or fish vertebrae included: 45% (n=45) of patients below age 40 years, 35% (n=12) of women, 41% (n=15) of drug detoxification patients, 58% (n=22) of alcohol detoxification patients, 48% (n=36) of drug and alcohol detoxification patients, and 47% (n=17) of patients with elevated serum inorganic phosphorus (P=NS). Six percent (n=9) of our study population had nonspinal fractures on their chest radiographs. Twenty-one percent (n=14) of controls had complications of osteopenia in the thoracic spine (all anterior wedging). This prevalence differed significantly (P<0.05, chi-squared) from the study population

Full Text Available In the present study, the enrichment and isolation of textile effluent decolorizing bacteria were carried out in wheat bran (WB medium. The isolated bacterium Providencia rettgeri strain HSL1 was then tested for decolorization of textile effluent in consortium with a dyestuff degrading fungus Aspergillus ochraceus NCIM 1146. Decolorization study suggests that A. ochraceus NCIM 1146 and P. rettgeri strain HSL1 alone re moves only 6 and 32% of textile effluent American Dye Manufacturing Institute respectively in 30 h at 30 ±0.2°C of microaerophilic incubation, while the fungal-bacterial consortium does 92% ADMI removal within the same time period. The fungal-bacterial consortium exhibited enhanced decolorization rate due to the induction in activities of catalytic enzymes laccase (196%, lignin peroxidase (77%, azoreductase (80% and NADH-DCIP reductase (84%. The HPLC analysis confirmed the biodegradation of textile effluent into various metabolites. Detoxification studies of textile effluent before and after treatment with fungal-bacterial consortium revealed reduced toxicity of degradation metabolites. The efficient degradation and detoxification by fungal-bacterial consortium pre-grown in agricultural based medium thus suggest a promising approach in designing low-cost treatment technologies for textile effluent.

It is widely recognized that smoking is related to abdominal pain and discomfort, as well as gastrointestinal disorders. Research has shown that visceral sensitivity, experiencing anxiety around gastrointestinal sensations, is associated with poorer gastrointestinal health and related health outcomes. Visceral sensitivity also increases anxiety symptoms and mediates the relation with other risk factors, including gastrointestinal distress. No work to date, however, has evaluated visceral sensitivity in the context of smoking despite the strong association between smoking and poor physical and mental health. The current study sought to examine visceral sensitivity as a unique predictor of cigarette dependence, threat-related smoking abstinence expectancies (somatic symptoms and harmful consequences), and perceived barriers for cessation via anxiety symptoms. Eighty-four treatment seeking adult daily smokers (M age =45.1years [SD=10.4]; 71.6% male) participated in this study. There was a statistically significant indirect effect of visceral sensitivity via general anxiety symptoms on cigarette dependence (b=0.02, SE=0.01, Bootstrapped 95% CI [0.006, 0.05]), smoking abstinence somatic expectancies (b=0.10, SE=0.03, Bootstrapped 95% CI [0.03, 0.19]), smoking abstinence harmful experiences (b=0.13, SE=0.05, Bootstrapped 95% CI [0.03, 0.25]), and barriers to cessation (b=0.05, SE=0.06, Bootstrapped 95% CI [0.01, 0.13]). Overall, the present study serves as an initial investigation into the nature of the associations between visceral sensitivity, anxiety symptoms, and clinically significant smoking processes among treatment-seeking smokers. Future work is needed to explore the extent to which anxiety accounts for relations between visceral sensitivity and other smoking processes (e.g., withdrawal, cessation outcome).

Studies show higher lifetime prevalence of suicidality in individuals with pathological gambling. However, less is known about the relationship between pathological gambling and current suicidal ideation. We investigated socio-demographic, clinical and gambling-related variables associated with suicidality in treatment-seeking individuals. Bivariate analyses and logistic regression models were generated on data from 903 individuals to identify measures associated with aspects of suicidality. Forty-six percent of patients reported current suicidal ideation. People with current suicidal thoughts were more likely to report greater problem-gambling severity (psuicidality. Logistic regression models suggested that past suicidal ideation (psuicidality. Our findings suggest that the severity of anxiety disorder, along with a lifetime history of suicidal ideation, may help to identify treatment-seeking individuals with pathological gambling with a higher risk of suicidality, highlighting the importance of assessing suicidal ideation in clinical settings.

Carboxylesterases (CarEs) are involved in metabolic detoxification of dietary and environmental xenobiotics in insects. However, owing to the complexity of the protein family, the involvement of CarEs in insecticide metabolism in Plutella xylostella has not been fully elucidated. This study aimed to characterise two CarE genes and assess their potential roles in response to chlorpyrifos in P. xylostella. Synergistic tests showed that triphenyl phosphate decreased the resistance of the third-instar larvae to chlorpyrifos. The treatment of the third-instar larvae with chlorpyrifos at the LC 30 dose led to a significant increase in CarE activity. Two CarE cDNAs (Pxae18 and Pxae28) were subsequently sequenced and characterised. Both genes were expressed predominantly in the larval midgut. Most importantly, two CarE genes showed significantly higher expression in the chlorpyrifos-resistant strain than in the susceptible strain. RNAi knockdown of Pxae18 and Pxae28 significantly increased the mortality to chlorpyrifos from 40% in the control to 73.8 and 63.3% respectively. RNAi knockdown of Pxae18 and Pxae28 significantly inhibited detoxification ability and increased the mortality in P. xylostella. The results indicate that these two CarE genes play important roles in the detoxification of chlorpyrifos in P. xylostella. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Full Text Available Background. In previous studies, people’s knowledge of reproductive health and infertile women’s psychological states was surveyed in several countries. However, there has been limited information concerning the psychological states of infertile women seeking treatment and the outcomes of in vitro fertilization (IVF in China. Methods. Infertile women were asked to complete short questionnaires on the day that their oocytes were retrieved; these questionnaires covered the durations of their infertility, levels of education, sources of pressure, and psychological states. Data concerning IVF outcomes were provided by embryologists and clinicians. The correlations between the duration of infertility and educational level, psychological state and education level, and psychological state and outcome of IVF were analyzed in the cohort study. Results. The duration of infertility in more than half of the females was longer than 5 years. Compared with less-educated women, women with higher levels of education sought treatment earlier and their rates of depressive symptoms were lower. There is an association between negative emotions and outcome of IVF. Conclusions. The survey of the situations of infertile women seeking IVF treatment in China indicates the importance of popularizing knowledge concerning reproductive health. Improving medical conditions, reducing the costs of treatment, and developing social culture will aid in relieving the stress of infertile women and improving assisted reproductive treatment.

The aim of Phase II of the Men's Attitudes to Life Events and Sexuality (MALES) Study is to explore PDE5 inhibitor treatment seeking among men with erectile dysfunction (ED). Phase II of the MALES study involved 2,912 men, aged 20-75 years, from 8 countries (U.S., U.K., Germany, France, Italy, Spain, Mexico, and Brazil), who reported ED. Participants were recruited from the MALES Phase I sample [1] and via booster methods (e.g., physician referral, street interception), and completed self-report questionnaires concerning the characteristics of their ED, their efforts to seek PDE5 inhibitor treatment for their sexual dysfunction, and attitudinal and referent influences that potentially affect treatment-seeking. Statistical analyses focus on identification of correlates of PDE5 inhibitor treatment seeking. PDE5 inhibitor utilization is strongly associated with ED sufferers' assessment of the severity of their sexual dysfunction, with their belief that medication for ED is dangerous, and with their perceptions of whether physicians, other professionals, and spouses or family members are supportive of their seeking treatment. ED sufferers who evaluate their sexual dysfunction as severe, who believe that medication for ED is not dangerous, and who perceive support for treatment seeking from referent others, are more likely to utilize PDE5 inhibitor treatment. Findings indicate that perceived ED severity, beliefs about ED medication, and referent influences are strongly correlated with utilization of PDE5 inhibitor therapy. These findings aid our understanding of factors that may incline men with ED to seek-or to avoid-PDE5 inhibitor therapy for their sexual dysfunction, and provide a basis for clinical and educational interventions to assist men with ED to seek appropriate treatment.

Consumer feedback identifies a new challenge in the treatment of borderline personality disorder (BPD) is to address the discrepancy between clinical treatment targets and the more personally meaningful goals people are seeking in treatment. This highlights the need to increase clarification of people's values and link these to therapy goals. The current study explores ways in which individuals with BPD identify with values across key life domains. At initial assessment 106 consumer participants attending an outpatient clinic for the treatment of BPD completed the Personal Values Questionnaire by Blackledge and colleagues. This 90-item measure asks participants to respond to different value appraisals such as importance, commitment, desire to improve, success and, motivation across nine life domains. These included: relationships, health & wellbeing, education & personal development, work & career, spirituality, recreation & leisure, and community involvement. A consistent pattern of value appraisals was found across all life domains. Specifically, life domains were endorsed as highly important but participants reported significantly lower levels of value commitment, desire to improve and success. Successful value pursuit also related differentially to value motivations (internal vs. external) depending on the particular life domain. Relationships with family, friends and romantic partners, as well as health & wellbeing were most important compared to other life domains. The findings suggest that people with BPD identify with values and prioritise different life domains in terms of importance. Our results show discrepancies between higher importance and lower commitment, desire to improve and success at living in line with what is valued. Identification of such discrepancies provides opportunities to more effectively support consumers with BPD to prioritise goals that are consistent with valued domains. These findings offer new insights for cultivating the

Disentangling detoxification: gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms.

Full Text Available The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of central and eastern Canada and the USA. We conducted a large-scale gene expression analysis (RNA-seq of mountain pine beetle male and female adults either starved or fed in male-female pairs for 24 hours on lodgepole pine host tree tissues. Our aim was to uncover transcripts involved in coniferophagous mountain pine beetle detoxification systems during early host colonization. Transcripts of members from several gene families significantly increased in insects fed on host tissue including: cytochromes P450, glucosyl transferases and glutathione S-transferases, esterases, and one ABC transporter. Other significantly increasing transcripts with potential roles in detoxification of host defenses included alcohol dehydrogenases and a group of unexpected transcripts whose products may play an, as yet, undiscovered role in host colonization by mountain pine beetle.

Reducing readmissions to detoxification: an interorganizational network perspective.

Spear, Suzanne E

The high cost of detoxification (detox) services and health risks associated with continued substance abuse make readmission to detox an important indicator of poor performance for substance use disorder treatment systems. This study examined the extent to which the structure of local networks available to detox programs affects patients' odds of readmission to detox within 1 year. Administrative data from 32 counties in California in 2008-2009 were used to map network ties between programs based on patient transfers. Social network analysis was employed to measure structural features of detox program networks. Contextual predictors included efficiency (proportion of ties within a network that are non-redundant) and out-degree (number of outgoing ties to other programs). A binary mixed model was used to predict the odds of readmission among detox patients in residential (non-hospital) facilities (N=18,278). After adjusting for patient-level covariates and continuity of service from detox to outpatient or residential treatment, network efficiency was associated with lower odds of readmission. The impact of network structure on detox readmissions suggests that the interorganizational context in which detox programs operate may be important for improving continuity of service within substance use disorder treatment systems. Implications for future research are discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Few studies have examined the co-morbidity between insomnia and sleep-disordered breathing in the clinical setting. This study evaluated treatment-seeking insomnia patients and their self-report of sleep breathing complaints. A retrospective chart review was conducted on 1,035 consecutive treatment-seeking, chronic insomnia patients who reported insomnia as their primary problem upon seeking care at a private, community-based sleep medical center. Measurements included the insomnia severity index, standard subjective sleep measures as well as rankings, attributions, and self-reports about sleep breathing disorders, problems, and symptoms. A total of 1,035 adult, treatment-seeking insomnia patients indicated insomnia interfered with daytime functioning, and their average insomnia severity was in the range of a clinically relevant problem: total sleep time (5.50 h, SD = 1.60), sleep efficiency (71.05 %, SD = 18.26), wake time after sleep onset (120.70 min, SD = 92.56), and an insomnia severity index (18.81, SD = 5.09). Of these 1,035 insomnia patients, 42 % also ranked a sleep breathing disorder among their list of reasons for seeking treatment, another 13 % revealed a concern about a sleep breathing problem, and another 26 % reported awareness of sleep breathing symptoms. Only 19 % of this clinical insomnia sample reported no awareness or concerns about sleep breathing disorders, problems, or symptoms. A greater proportion of men than women reported significantly more sleep breathing disorders, problems, or symptoms. Sleep breathing complaints were extremely common among a large sample of treatment-seeking, self-identified, adult chronic insomnia patients. Prospective prevalence research is needed to corroborate or revise these findings, and polysomnography should be considered in appropriate cohorts to determine the clinical relevance of treatment-seeking chronic insomnia patients' sleep breathing complaints.

Obstetric fistula classic symptoms of faecal and urinary incontinence cause women to live with social stigma, isolation, psychological trauma and lose their source of livelihoods. There is a paucity of studies on the health seeking behaviour trajectories of women with fistula illness although women live with the illness for decades before surgery. We set out to establish the complete picture of women's health seeking behaviour using qualitative research. We sought to answer the question: what patterns of health seeking do women with obstetric fistula display in their quest for healing? We used grounded theory methodology to analyse data from narratives of women during inpatient stay after fistula surgery in 3 hospitals in Kenya. Emergent themes contributed to generation of substantive theory and a conceptual framework on the health seeking behaviour of fistula patients. We recruited 121 participants aged 17 to 62 years whose treatment pathways are presented. Participants delayed health seeking, living with fistula illness after their first encounter with unresponsive hospitals. The health seeking trajectory is characterized by long episodes of staying home with illness for decades and consulting multiple actors. Staying with fistula illness entailed health seeking through seven key actions of staying home, trying home remedies, consulting with private health care providers, Non-Governmental organisations, prayer, traditional medicine and formal hospitals and clinics. Long treatment trajectories at hospital resulted from multiple hospital visits and surgeries. Seeking treatment at hospital is the most popular step for most women after recognizing fistula symptoms. We conclude that the formal health system is not responsive to women's needs during fistula illness. Women suffer an illness with a chronic trajectory and seek alternative forms of care that are not ideally placed to treat fistula illness. The results suggest that a robust health system be provided with

Many applications of probiotics have been described up to date. In this paper, it is hypothesized that probiotic microorganisms can also be used to decrease the xenobiotics intake in humans. The use of probiotic bacteria (e.g. strains of Lactobacillus sp. and Bifidobacterium Sp.) and Yeasts (Saccharomyces sp.) gives the opportunity for detoxification of various elements and compounds, considered as contaminants, directly in the lumen of human intestine. Some of these microorganisms ar known to accumulate cesium, strontium and heavy metals to a great extent and also bind mycotoxins. Certainly, during the up-coming years, their native or genetically modified strains will be a part of treatment protocols in detoxication therapy. The utilization of probiotics, in the both therapy and nutrition of people living in the countries suffering from high food contamination, could result in the reduction of annual xenobiotic dose to be incorporated in their organisms.

Gambling Disorder (GD) is characterized by recurrent gambling behavior that is associated with significant impairment and distress, high psychiatric comorbidities, and high functional disability. The military veteran population appears particularly susceptible to developing the disorder, but relatively little has been studied among this population. The purpose of the present study is to investigate the clinical psychopathologies and comorbidities of veterans seeking treatment for problem gambling and how problem gambling may impact functioning. Treatment-seeking veterans meeting criteria for GD (N = 61) underwent a structured clinical interview and completed the South Oaks Gambling Screen (SOGS), the Gambling Symptom Assessment Scale (G-SAS), the Yale-Brown Obsessive-Compulsive Scale for Gambling Disorder (PG-YBOCS), the Gambling Belief Questionnaire (GBQ), the Barratt Impulsiveness Scale (BIS-11), and the Sheehan Disability Scale (SDS). Veterans seeking treatment for GD had high rates of psychiatric and addiction disorder comorbidities. Few veterans had previously sought treatment and most reported substantive challenges in social and occupational functioning. When determining how gambling-related characteristics (ie, severity and cognitive distortions) impact function, severity of cognitive distortions was the strongest statistical predictor of overall functional disability. The findings from this study indicate that there is high comorbidity between GD and other psychiatric and addictive disorders, as well as social and occupational functioning. In addition, cognitive distortions related to gambling relate importantly to overall functioning and should be considered in the development of interventions for veterans with GD.

Progressive fibrosis accompanies all chronic renal disease, connective tissue growth factor (CTGF,) and platelet-derived growth factor-B, (PDGF-B,) play important roles in extra-cellular matrix abnormal accumulation, while endothelin-1 (ET-1) nitric oxide (NO,) are related to endothelial dysfunction, which mediates the progression of renal fibrosis. Shenqi Detoxification Granule (SDG), a traditional Chinese herbal formula, has been used for treatment of chronic renal failure in clinic for many years. In order to evaluate the efficacy, and explore the mechanism of SDG to inhibit the progression of renal fibrosis, study was carried out using the adenine-induced Wister rats as the CRF model, and losartan as postive control drug. Levels of serum creatinine [Scr], and blood urea nitrogen (BUN), albumin (ALB), 24hrs, urine protein (24hUP), triacylglycerol (TG), and cholesterol (CHO), together with ET-1, and NO were detected. Pathological changes of renal tissues were observed by HE, staining. In addition, CTGF and PDGF-B expression were analyzed by immuno-histo-chemistry. The results indicated that SDG can effectively reduce Scr, BUN, 24hUP, TG, and CHO levels, increase ALB levels, inhibit renal tissue damage in CRF rats, and the mechanism maybe reduce PDGF-B, CTGF expression and ET-1/NO. Shenqi Detoxification Granule is a beneficial treatment for chronic renal failure.

The administration of dopaminergic medication to treat the symptoms of Parkinson’s disease (PD) is associated with addictive behaviors and impulse control disorders. Little is known, however, on how PD patients differ from other patients seeking treatments for behavioral addictions. The aim of this study was to compare the characteristics of behavioral addiction patients with and without PD. N = 2,460 treatment-seeking men diagnosed with a behavioral addiction were recruited from a university hospital. Sociodemographic, impulsivity [Barratt Impulsiveness Scale (BIS-11)], and personality [Temperament and Character Inventory-Revised (TCI-R)] measures were taken upon admission to outpatient treatment. Patients in the PD group were older and had a higher prevalence of mood disorders than patients without PD. In terms of personality characteristics and impulsivity traits, PD patients appeared to present a more functional profile than PD-free patients with a behavioral addiction. Our results suggest that PD patients with a behavioral addiction could be more difficult to detect than their PD-free counterparts in behavioral addiction clinical setting due to their reduced levels of impulsivity and more standard personality traits. As a whole, this suggests that PD patients with a behavioral addiction may have different needs from PD-free behavioral addiction patients and that they could potentially benefit from targeted interventions.

Full Text Available Abstract Background Early diagnosis and prompt effective case management are important components of any malaria elimination strategy. Tafea Province, Vanuatu has a rich history of traditional practices and beliefs, which have been integrated with missionary efforts and the introduction of modern constructions of health. Gaining a detailed knowledge of community perceptions of malarial symptomatology and treatment-seeking behaviours is essential in guiding effective community participation strategies for malaria control and elimination. Method An ethnographic study involving nine focus group discussions (FGD, 12 key informant interviews (KII and seven participatory workshops were carried out on Tanna Island, Vanuatu. Villages in areas of high and low malaria transmission risk were selected. Four ni-Vanuatu research officers, including two from Tanna, were trained and employed to conduct the research. Data underwent thematic analysis to examine treatment-seeking behaviour and community perceptions of malaria. Results Malaria was perceived to be a serious, but relatively new condition, and in most communities, identified as being apparent only after independence in 1980. Severe fever in the presence of other key symptoms triggered a diagnosis of malaria by individuals. Use of traditional or home practices was common: perceived vulnerability of patient and previous experience with malaria impacted on the time taken to seek treatment at a health facility. Barriers to health care access and reasons for delay in care-seeking included the availability of health worker and poor community infrastructure. Conclusion Due to programme success of achieving low malaria transmission, Tafea province has been identified for elimination of malaria by 2012 in the Government of Vanuatu Malaria Action Plans (MAP. An effective malaria elimination programme requires interactions between the community and its leaders, malaria workers and health providers for success in

Comparison of drug treatment histories of single and multiple drug abusers in detox.

Greberman, S B; Jasinski, D

2001-01-01

This study was undertaken to determine differences in previous treatment patterns in individuals currently using different numbers of substances. Medical records of 1198 inpatient detoxification (detox) admissions were analyzed. Numbers of past admissions to completed detox, methadone, or other types of drug abuse treatment were totaled and ranked to determine most frequent type. Within gender, treatment histories of single and multiple drug abusers usually do not differ. The one exception is male multiple drug abusers ages 26-30, who show increased admissions. Possible explanations are that men do not seek treatment before developing medical complications of addiction or until external factors influence admission. There were differences in treatment histories between genders in multiple drug abusers only. Before age 30, women reported increased treatment of certain types. Possible explanations are that treatment priority is given to women who are, or may be, pregnant. Also, younger men may not enter or complete treatment. Previous treatment history may influence many behaviors. The results of this study delineate several valuable indicators for assessing past history.

The robust supramolecular structure of biomass often requires severe pretreatments conditions to produce soluble sugars. Nonetheless, these processes generate some inhibitory compounds (i.e. furans compounds and aliphatic acids) deriving mainly from sugars degradation. To avoid the inhibition of the biological process and to obtain satisfactory sugars conversion level into biofuels, a detoxification step is required. This study investigates the use of two pyrochars derived from solid anaerobic digestates for the detoxification of lignocellulosic hydrolysates. At a pyrochar concentration of 40gL(-1), more than 94% of 5-HMF and 99% of furfural were removed in the synthetic medium after 24h of contact time, whereas sugars concentration remained unchanged. Furfural was adsorbed faster than 5-HMF by both pyrochars and totally removed after 3h of contact. Finally, the two pyrochars were found efficient in the detoxification of corn stalks and Douglas fir wood chips hydrolysates without affecting the soluble sugars concentrations.

Timely access to appropriate treatment is important for optimizing insomnia management. To date, little is known about insomnia patients' treatment experiences or how they access and engage with the available health care resources. This study sought to capture the help-seeking experiences and behavioral patterns of patients with insomnia who are seeking or receiving specialist care. A purposive sample of 26 insomnia patients from specialist sleep and mental health clinics located in metropolitan New South Wales, Australia was recruited. Participants completed a brief questionnaire, followed by an in-depth, semi-structured interview. Interviews were digitally recorded, transcribed verbatim, and analyzed using framework analysis. Three key themes emerged from the data: patients' sleep beliefs, treatment beliefs, and accessing specialized care. The findings show that daytime symptoms arising from insomnia serve as important illness cues for patients to seek medical help. In addition, participants' treatment pathways highlight factors that prevent the widespread use of cognitive behavioral therapy for insomnia (CBT-I), including limited awareness about CBT-I, tentative referral mechanisms, limited service providers, and the high cost of CBT-I.

Highlights: •TiO 2 NPs cytotoxicity at low exposure levels (≤1 μg/mL) to freshwater algae. •ROS generation, NP adsorption and internalization contributors to toxicity. •Observational evidence of genotoxicity by nanoparticles in an algal cell. •Reduced bioavailability thus detoxification of NPs by microalgae. •Possible role of EPS in detoxification. -- Abstract: In the current study, two aspects concerning (i) the cytotoxicity potential of TiO 2 nanoparticles (NPs) toward freshwater algal isolate Scenedesmus obliquus and (ii) the potential detoxification of NPs by the microalgae were assessed under light (UV-illumination) and dark conditions at low exposure levels (≤1 μg/mL), using sterile freshwater as the test medium. The statistically significant reduction in cell viability, increase in reactive oxygen species production and membrane permeability (light vs. dark) suggested photo-induced toxicity of TiO 2 NPs. The electron micrographs demonstrated adsorption of the NPs onto the cell surface and substantiated their internalization/uptake. The fluorescence micrographs and the confocal laser scanning (CLSM) images suggested the absence of a definite/intact nucleus in the light treated cells pointing toward the probable genotoxic effects of NPs. In a separate three cycle experiment, a continuous decrease in the cytotoxicity was observed, whereas, at the end of each cycle only fresh algae were added to the supernatant containing NPs from the previous cycle. The decreasing concentrations of the NPs in the subsequent cycles owing to agglomeration–sedimentation processes exacerbated by the algal interactions played a crucial role in the detoxification. In addition, the exo-polymeric substances produced by the cells could have rendered the available NPs less reactive, thereby, enhancing the detoxification effects

To examine whether self-stigma of seeking psychological help and being male would be associated with an increased likelihood of having an undiagnosed eating disorder. A multi-national sample of 360 individuals with diagnosed eating disorders and 125 individuals with undiagnosed eating disorders were recruited. Logistic regression was used to identify variables affecting the likelihood of having an undiagnosed eating disorder, including sex, self-stigma of seeking psychological help, and perceived stigma of having a mental illness, controlling for a broad range of covariates. Being male and reporting greater self-stigma of seeking psychological help was independently associated with an increased likelihood of being undiagnosed. Further, the association between self-stigma of seeking psychological help and increased likelihood of being undiagnosed was significantly stronger for males than for females. Perceived stigma associated with help-seeking may be a salient barrier to treatment for eating disorders-particularly among male sufferers. © 2015 Wiley Periodicals, Inc.

Traditional medicine is commonly assumed to be a crucial health care option for poor households in developing countries. However, little research has been done in Asia to quantify the reliance on traditional medicine and its determinants. This research contributes to filling in this knowledge gap using household survey data collected from 571 households in three rural and peri-urban sites in Nepal in 2012. Questions encompassed household socioeconomic characteristics, illness characteristics, and treatment-seeking behaviour. Treatment choice was investigated through bivariate analyses. Results show that traditional medicine, and especially self-treatment with medicinal plants, prevail as treatment options in both rural and peri-urban populations. Contrarily to what is commonly assumed, high income is an important determinant of use of traditional medicine. Likewise, knowledge of medicinal plants, age, education, gender and illness chronicity were also significant determinants. The importance of self-treatment with medicinal plants should inform the development of health policy tailored to people’s treatment-seeking behaviour. PMID:26130610

This article evaluates the results of a workplace violence prevention program implemented in a Colorado detoxification facility. The program interventions are modeled after federal Occupational Safety and Health Administration guidelines and use theories from both nursing and criminology for philosophy and direction. Serving as its own control, the detoxification facility shares data measured over a 4-year period, demonstrating a sharp decline in assault rates after program implementation. The importance of administrative controls, environmental adjustments, recordkeeping and evaluation, and education and training are emphasized as key components of success.

2012-11-01

Full Text Available Abstract Background The genomes of three major mosquito vectors of human diseases, Anopheles gambiae, Aedes aegypti, and Culex pipiens quinquefasciatus, have been previously sequenced. C. p. quinquefasciatus has the largest number of predicted protein-coding genes, which partially results from the expansion of three detoxification gene families: cytochrome P450 monooxygenases (P450, glutathione S-transferases (GST, and carboxyl/cholinesterases (CCE. However, unlike An. gambiae and Ae. aegypti, which have large amounts of gene expression data, C. p. quinquefasciatus has limited transcriptomic resources. Knowledge of complete gene expression information is very important for the exploration of the functions of genes involved in specific biological processes. In the present study, the three detoxification gene families of C. p. quinquefasciatus were analyzed for phylogenetic classification and compared with those of three other dipteran insects. Gene expression during various developmental stages and the differential expression responsible for parathion resistance were profiled using the digital gene expression (DGE technique. Results A total of 302 detoxification genes were found in C. p. quinquefasciatus, including 71 CCE, 196 P450, and 35 cytosolic GST genes. Compared with three other dipteran species, gene expansion in Culex mainly occurred in the CCE and P450 families, where the genes of α-esterases, juvenile hormone esterases, and CYP325 of the CYP4 subfamily showed the most pronounced expansion on the genome. For the five DGE libraries, 3.5-3.8 million raw tags were generated and mapped to 13314 reference genes. Among 302 detoxification genes, 225 (75% were detected for expression in at least one DGE library. One fourth of the CCE and P450 genes were detected uniquely in one stage, indicating potential developmentally regulated expression. A total of 1511 genes showed different expression levels between a parathion-resistant and a

Insecticides are thought to be among the major factors contributing to current declines in bee populations. However, detoxification mechanisms in healthy, unstressed honey bees are poorly characterised. Alkaloids are naturally encountered in pollen and nectar, and we used nicotine as a model compound to identify the mechanisms involved in detoxification processes in honey bees. Nicotine and neonicotinoids have similar modes of action in insects. Our metabolomic and proteomic analyses show active detoxification of nicotine in bees, associated with increased energetic investment and also antioxidant and heat shock responses. The increased energetic investment is significant in view of the interactions of pesticides with diseases such as Nosema spp which cause energetic stress and possible malnutrition. Understanding how healthy honey bees process dietary toxins under unstressed conditions will help clarify how pesticides, alone or in synergy with other stress factors, lead to declines in bee vitality.

Objective: This study was aimed to assess oral cancer awareness among a selected Sudanese population and to evaluate their knowledge and treatment seeking behavior. Methods: A questionnaire- based survey was performed on the general population who attended the oral cancer awareness campaigns carried between 2015 and 2016 in different geographic areas of the Sudan. It was focusing on general awareness of oral cancer, oral cancer risk factors, oral cancer clinical signs/symptoms and treatment seeking behavior. Data were entered by Microsoft excel 2007 and analyzed by SPSS (version 20) using chi square test with P value oral cancer and the media was the common source of information (75.7%). Of all participants only 45.3% mentioned that they don’t have enough knowledge on oral cancer. Some participants believe that oral cancer is treatable (66.5%) whilst 30.4% respond by I don’t know. More than 80% of the respondents were aware that smokeless tobacco (toombak) is a risk factor for oral cancer. While 60.1% were aware of alcohol as a risk factor and 66.2% were aware of smoking as a risk factor. When qui square test was done, smokers were found to be the least to seek help in comparison to non-smokers. The same result was obtained from alcohol consumers but it was different in snuff dippers, as the latter response was similar to that of the non-snuff dippers. Conclusion: This study revealed a level of around 66.6% of oral cancer awareness in different states of Sudan. Counseling sessions should be conducted when necessary with further investigations to find out the reasons behind the continued practice of high risk habits, despite knowledge.

2007-08-01

Full Text Available Abstract Background The literature on health care seeking behaviour in sub-Saharan Africa for children suffering from malaria is quite extensive. This literature, however, is predominately quantitative and, inevitably, fails to explore how the local concepts of illness may affect people's choices. Understanding local concepts of illness and their influence on health care-seeking behaviour can complement existing knowledge and lead to the development of more effective malaria control interventions. Methods In a rural area of Burkina Faso, four local concepts of illness resembling the biomedical picture of malaria were described according to symptoms, aetiology, and treatment. Data were collected through eight focus group discussions, 17 semi-structured interviews with key informants, and through the analysis of 100 verbal autopsy questionnaires of children under-five diagnosed with malaria. Results Sumaya, dusukun yelema, kono, and djoliban were identified as the four main local illness concepts resembling respectively uncomplicated malaria, respiratory distress syndrome, cerebral malaria, and severe anaemia. The local disease categorization was found to affect both treatment and provider choice. While sumaya is usually treated by a mix of traditional and modern methods, dusukun yelema and kono are preferably treated by traditional healers, and djoliban is preferably treated in modern health facilities. Besides the conceptualization of illness, poverty was found to be another important influencing factor of health care-seeking behaviour. Conclusion The findings complement previous evidence on health care-seeking behaviour, by showing how local concepts of illness strongly influence treatment and choice of provider. Local concepts of illness need to be considered when developing specific malaria control programmes.

Full Text Available The administration of dopaminergic medication to treat the symptoms of Parkinson’s disease (PD is associated with addictive behaviors and impulse control disorders. Little is known, however, on how PD patients differ from other patients seeking treatments for behavioral addictions. The aim of this study was to compare the characteristics of behavioral addiction patients with and without PD. N = 2,460 treatment-seeking men diagnosed with a behavioral addiction were recruited from a university hospital. Sociodemographic, impulsivity [Barratt Impulsiveness Scale (BIS-11], and personality [Temperament and Character Inventory-Revised (TCI-R] measures were taken upon admission to outpatient treatment. Patients in the PD group were older and had a higher prevalence of mood disorders than patients without PD. In terms of personality characteristics and impulsivity traits, PD patients appeared to present a more functional profile than PD-free patients with a behavioral addiction. Our results suggest that PD patients with a behavioral addiction could be more difficult to detect than their PD-free counterparts in behavioral addiction clinical setting due to their reduced levels of impulsivity and more standard personality traits. As a whole, this suggests that PD patients with a behavioral addiction may have different needs from PD-free behavioral addiction patients and that they could potentially benefit from targeted interventions.

Spiritual Struggle Among Patients Seeking Treatment for Chronic Headaches: Anger and Protest Behaviors Toward God.

Exline, Julie J; Krause, Steven J; Broer, Karen A

2016-10-01

This study examined anger and protest behaviors toward God among 80 US adults seeking treatment for chronic headaches (66 women, 14 men; 71 completed treatment). Measures were administered before and after an intensive 3-week outpatient treatment program. At both times, anger and protest toward God correlated with lower pain acceptance, more emotional distress, and greater perceived disability. However, when considered simultaneously, anger predicted sustained distress, whereas protest behaviors (e.g., complaining, questioning, arguing) predicted both reduced distress and an increased sense of meaning. These findings suggest the utility of distinguishing between anger toward God and behaviors suggesting assertiveness toward God.

2017-03-01

The objective of this study is to provide a comprehensive review of empirical research exploring barriers to and facilitators of initial treatment seeking ("first contact") from professional health care providers by adults and young adults with eating disorders (EDs). A search of databases PsycINFO and MEDLINE using the terms "treatment" and "eating disorder*" yielded 9,468 peer-reviewed articles published from January 1945 to June 2016. Screening identified 31 articles meeting the following criteria: (1) participants were 16 or older and presented with a self-reported or clinically diagnosed ED; (2) studies focused on (a) initial treatment seeking (b) for an ED (c) from professional health care providers; (3) articles were empirical, and (4) peer reviewed. Quantitative studies revealed few consistent correlates of treatment seeking, perhaps because most variables were examined in only one or two investigations. Variables with some degree of predictive utility (i.e., produced significant results in multiple studies) were age (older), ethnicity (nonethnic minority), ED type (anorexia, purging BN), specific ED-related behaviors (i.e., purging), and time spent on a treatment waitlist following referral (less). Although BMI was one of the most investigated variables, it did not predict treatment seeking. Qualitative studies revealed the following perceived barriers: (1) personal feelings of shame/fear, (2) ED-related beliefs/perceptions, (3) lack of access/availability, and (4) aspects of the treatment process. Perceived facilitators included (1) health-related concerns, (2) emotional distress, and (3) social support. Implications for clinical practice and areas for further research are discussed. Results highlight the need for shared definitions and methodologies across studies of treatment seeking. © 2017 Wiley Periodicals, Inc.

The Hunt bumble bee (Bombus huntii Greene, Hymenoptera: Apidae) is a holometabolous, social insect important as a pollinator in natural and agricultural ecosystems in western North America. Bumble bees spend a significant amount of time foraging on a wide variety of flowering plants, and this activity exposes them to both plant toxins and pesticides, posing a threat to individual and colony survival. Little is known about what detoxification pathways are active in bumble bees, how the expression of detoxification genes changes across life stages, or how the number of detoxification genes expressed in B. huntii compares to other insects. We found B. huntii expressed at least 584 genes associated with detoxification and stress responses. The expression levels of some of these genes, such as those encoding the cytochrome P450s, glutathione S-transferases (GSTs) and glycosidases, vary among different life stages to a greater extent than do other genes. We also found that the number of P450s, GSTs and esterase genes expressed by B. huntii is similar to the number of these genes found in the genomes of other bees, namely Bombus terrestris, Bombus impatiens, Apis mellifera and Megachile rotundata, but many fewer than are found in the fly Drosophila melanogaster. Bombus huntii has transcripts for a large number of detoxification and stress related proteins, including oxidation and reduction enzymes, conjugation enzymes, hydrolytic enzymes, ABC transporters, cadherins, and heat shock proteins. The diversity of genes expressed within some detoxification pathways varies among the life stages and castes, and we typically identified more genes in the adult females than in larvae, pupae, or adult males, for most pathways. Meanwhile, we found the numbers of detoxification and stress genes expressed by B. huntii to be more similar to other bees than to the fruit fly. The low number of detoxification genes, first noted in the honey bee, appears to be a common phenomenon among bees

This article presents a comparative analysis of socio-economic disparities in relation to treatment-seeking strategies and healthcare expenditures in poor neighbourhoods within larger health systems in four cities in India, Indonesia and Thailand. About 200 households in New Delhi, Bhubaneswar, Jogjakarta and Phitsanulok were repeatedly interviewed over 12 months to relate health problems with health seeking and health financing at household level. Quantitative data were complemented with ethnographic studies involving the same neighbourhoods and a number of private practitioners at each site. Within each site, the higher and lower income groups among the poor were compared. The lower income group was more likely than the higher income group to seek care from less qualified health providers and incur catastrophic health spending. The study recommends linking quality control mechanisms with universal health coverage (UHC) policies; to monitor the impact of UHC among the poorest; intervention research to reach the poorest with UHC; and inclusion of private providers without formal medical qualification in basic healthcare.

Modulation of Metabolic Detoxification Pathways Using Foods and Food-Derived Components: A Scientific Review with Clinical Application

Directory of Open Access Journals (Sweden)

Romilly E. Hodges

2015-01-01

Full Text Available Research into human biotransformation and elimination systems continues to evolve. Various clinical and in vivo studies have been undertaken to evaluate the effects of foods and food-derived components on the activity of detoxification pathways, including phase I cytochrome P450 enzymes, phase II conjugation enzymes, Nrf2 signaling, and metallothionein. This review summarizes the research in this area to date, highlighting the potential for foods and nutrients to support and/or modulate detoxification functions. Clinical applications to alter detoxification pathway activity and improve patient outcomes are considered, drawing on the growing understanding of the relationship between detoxification functions and different disease states, genetic polymorphisms, and drug-nutrient interactions. Some caution is recommended, however, due to the limitations of current research as well as indications that many nutrients exert biphasic, dose-dependent effects and that genetic polymorphisms may alter outcomes. A whole-foods approach may, therefore, be prudent.

Xylitol fermentation production from corncob acid hydrolysate has become an attractive and promising process. However, corncob acid hydrolysate cannot be directly used as fermentation substrate owing to various inhibitors. In this work, soaking in aqueous ammonia (SAA) pretreatment was employed to reduce the inhibitors in acid hydrolysate. After detoxification, the corncob acid hydrolysate was fermented by immobilized Candida tropicalis cell to produce xylitol. Results revealed that SAA pretreatment showed high delignification and efficient removal of acetyl group compounds without effect on cellulose and xylan content. Acetic acid was completely removed, and the content of phenolic compounds was reduced by 80%. Furthermore, kinetic behaviors of xylitol production by immobilized C. tropicalis cell were elucidated from corncob acid hydrolysate detoxified with SAA pretreatment and two-step adsorption method, respectively. The immobilized C. tropicalis cell showed higher productivity efficiency using the corncob acid hydrolysate as fermentation substrate after detoxification with SAA pretreatment than by two-step adsorption method in the five successive batch fermentation rounds. After the fifth round fermentation, about 60 g xylitol/L fermentation substrate was obtained for SAA pretreatment detoxification, while about 30 g xylitol/L fermentation substrate was obtained for two-step adsorption detoxification.

Although there is an interconnection between history of major depressive disorder and smoking, there has been relatively limited scientific attention oriented on the interplay between history of major depressive disorder and smoking maintenance processes. The current study sought to address whether history of major depressive disorder and post-cessation craving interact in the prediction of relapse among treatment-seeking smokers. Separate models were evaluated as a function of sex. Participants (n = 319, Mage = 41.7, 62.1% female) were treatment-seeking smokers who were abstinent at the end of six weekly 1-hour sessions involving psychosocial treatment for cessation. Participants completed a baseline assessment and reported post-cessation craving. Smoking status was assessed at 1-, 2-, 3-, 6-, and 12-month follow-up after the end of treatment. There was a significant interactive effect evident for females (B = 0.05, OR = 1.05, p = 0.013), but not males. The form of the interaction indicated females with history of major depressive disorder and greater post-treatment craving evinced the highest rate of relapse. Findings suggest that history of major depressive disorder and post-treatment craving are related to increased risk of relapse for female, but not male, smokers. Sex differences play a fundamental role in the explanation of the interaction of history of major depressive disorder and craving post-treatment in smoking relapse. Considering sex differences related to smoking relapse may help to tailor smoking cessation treatments.

Military service is associated with increased rates of heavy drinking. Widely used clinical practices (e.g., motivational interviewing) indicate that addressing both negative and positive drinking consequences is essential to effective treatment. However, research on effectively assessing positive drinking consequences in a clinical population is absent. The current study (1) evaluated the utility of the Positive Drinking Consequences Questionnaire (PDCQ), a measure previously validated in an undergraduate sample, for use with treatment-seeking veterans, and (2) evaluated relationships between positive drinking consequences and alcohol expectancies, pre-treatment alcohol use, and alcohol-related problems. Ninety-seven veterans seeking treatment for alcohol problems completed an anonymous survey (97.9% male; mean age = 49.76[11.40], 67.0% Caucasian). The PDCQ evidenced a single factor latent structure and internal consistency (Cronbach's alpha = .90). Positive drinking consequences and expectancies were related yet distinct constructs. After controlling for demographic factors, experiencing more positive drinking consequences at program intake was associated with heavier pretreatment drinking (ηp(2) = .10, p = .003) and alcohol-related problems (ηp(2) = .18, p alcohol use (ηp(2) = .12, p = .002) and alcohol-related problems (ηp(2) = .11, p = .003) when expectancies also were included in the model. Positive drinking consequences are assessed reliably by the PDCQ in a clinical sample and appear to play an important role in the drinking behavior of veterans seeking alcohol treatment.

The authors present an experimental study realized in order to simulate blood detoxification with the help of supermagnetic nanoparticles. The particles used are red oxide nanoparticles which are considered to be equivalent from a magnetic susceptibility and dynamic diameter point of view to the complex structures of magnetite nanoparticles. Two types of custom HGMS matrices have been used--a threaded one and a micro-spheres one. For testing red oxide particles have been purposefully created to have a lower magnetic susceptibility than magnetite or iron-carbon particles used in other experimental studies. Different concentrations of iron oxide, glycerine and water have been prepared, creating a 3.5 cP viscosity (equivalent to the one of the blood); the concentrations of the prepared solutions varied between 0.16 mg/mL and 2 mg/mL, with the background magnetic field value ranging from 0.25 T to 0.9 T, in order to observer the effectiveness of filtering at different intensities. The efficiency of HGMS filtering in experimental conditions was almost completely successful (99.99%) in all experimental conditions, both with the threaded and micro-spheres matrices. The high gradient magnetic separation system of nanoparticles has maximum efficiency and has the potential of being implemented in a medical blood detoxification device.

Red seaweed, Kappaphycus alvarezii, holds great promise for use in biofuel production due to its high carbohydrate content. In this study, we investigated the effect of fermentation inhibitors to the K. alvarezii hydrolysate on cell growth and ethanol fermentation. In addition, detoxification of fermentation inhibitors was performed to decrease the fermentation inhibitory effect. 5-Hydroxymethylfurfural and levulinic acid, which are liberated from acidic hydrolysis, was also observed in the hydrolysate of K. alvarezii. These compounds inhibited ethanol fermentation. In order to remove these inhibitors, activated charcoal and calcium hydroxide were introduced. The efficiency of activated charcoals was examined and over-liming was used to remove the inhibitors. Activated charcoal was found to be more effective than calcium hydroxide to remove the inhibitors. Detoxification by activated charcoal strongly improved the fermentability of dilute acid hydrolysate in the production of bioethanol from K. alvarezii with Saccharomyces cerevisiae. The optimal detoxifying conditions were found to be below an activated charcoal concentration of 5%.

Full Text Available Objectives: Little is known about the differences between urban and rural gamblers in Australia, in terms of comorbidity and treatment outcome. Health disparities exist between urban and rural areas in terms of accessibility, availability, and acceptability of treatment programs for problem gamblers. However, evidence supporting cognitive-behaviour therapy as the main treatment for problem gamblers is strong. This pilot study aimed to assess the outcome of a Cognitive-Behavioural Therapy (CBT treatment program offered to urban and rural treatment-seeking gamblers. Methods: People who presented for treatment at a nurse-led Cognitive-Behavioural Therapy (CBT gambling treatment service were invited to take part in this study. A standardised clinical assessment and treatment service was provided to all participants. A series of validated questionnaires were given to all participants at (a assessment, (b discharge, (c at a one-month, and (d at a 3-month follow-up visit. Results: Differences emerged between urban and rural treatment-seeking gamblers. While overall treatment outcomes were much the same at three months after treatment, rural gamblers appeared to respond more rapidly and to have sustained improvements over time. Conclusion: This study suggests that rural problem gamblers experience different levels of co-morbid anxiety and depression from their urban counterparts, but once in treatment appear to respond quicker. ACBT approach was found to be effective in treating rural gamblers and outcomes were maintained. Ensuring better availability and access to such treatment in rural areas is important. Nurses are in a position as the majority health professional in rural areas to provide such help.

Evidence suggests that the majority of people with suicidality do not seek help. Little systematic evaluation of factors influencing professional help-seeking has been done. To systematically evaluate the factors that influence professional help-seeking for suicidality. Published quantitative and qualitative studies in Medline and PsycInfo databases were reviewed following PRISMA. In all, 55 relevant studies were identified. Of these, 15 studies examined professional help-seeking intentions for perceived suicidal ideation, among people with or without suicidality; 21 studies examined professional help-seeking behavior among people with suicidality; and 19 studies examined suicidal decedents' health services use. Several potential important barriers were identified including high self-reliance, lack of perceived need for treatment, and stigmatizing attitudes toward suicide, toward mental health issues, and toward seeking professional treatment. The presence of suicidality and mental health issues was found to generally decrease help-seeking intentions for perceived suicidal ideation while facilitating actual service use. Social support and informal support from family and friends also played an important role in professional help-seeking. Although the majority of the included studies were of sound quality, some of the factors identified in the review were assessed in relatively few studies, and most of the included studies were conducted in industrialized countries. Further quantitative and qualitative studies examining the potential important factors in broader community samples, especially in developing countries, are needed.

Although Gamblers Anonymous (GA) is a popular intervention for gamblers, many attendees later present for professional treatment. This study evaluated gambling and psychosocial problems in individuals seeking professional treatment for gambling and compared those with and without a history of GA attendance. At intake to treatment, 342 pathological gamblers completed the Addiction Severity Index (ASI) and South Oaks Gambling Screen (SOGS). Fifty-four percent attended GA previously. Compared to non-GA attendees, GA attendees were older, had higher incomes, and were less likely to be single. They had higher SOGS scores, more years of gambling problems, and larger debts. GA attendees also had more serious family conflicts and less serious drug problems. Individuals with a history of GA attendance were more likely to be abstinent from gambling 2 months after treatment initiation. Logistic regression revealed that the number of professional sessions and GA meetings attended during treatment was independently associated with short-term abstinence. These data suggest that individuals entering professional treatment for gambling with a history of GA attendance differ from those who do not, and these differences may impact treatment recommendations and outcomes.

Hexavalent chromium (Cr 6+ ) compounds are hazardous via all exposure routes. To explore the dynamics of Cr accumulation and elimination and to reveal the mechanisms underlying detoxification and antioxidation in juvenile Gobiocypris rarus, one-month old G. rarus larvae were exposed to 0.1mgL -1 Cr 6+ for four weeks for accumulation and subsequently placed to clean water for another week for depuration. The contents of Cr were measured weekly in the whole body of G. rarus juveniles. The activities of catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), glutathione S-transferase (GST) and glutathione reductase (GR), and contents of glutathione (GSH) and malonaldehyde (MDA), and transcripts of cat, Cu/Zn-sod, Mn-sod, gpx1, gstpi, gr, mt1, nrf2 and uba52 were determined. The results indicated that G. rarus juveniles had a strong ability to resist the Cr accumulation by Cr 6+ exposure and to remove Cr from the body in clean water. In addition, GST and MT proteins may be involved in the detoxification of Cr 6+ . Moreover, Cr 6+ -induced GST detoxification in G. rarus juveniles might be accomplished through the Nrf2-mediated regulation of gene expressions. The antioxidant enzyme systems exhibited a response mechanism of the protective enzymes in organisms when they are subjected to external environmental stress. Two weeks of Cr 6+ treatments could have led to the damage and consecutive degradation of antioxidant enzymes via ubiquitination, and MT proteins could be involved in protecting the activity of these enzymes. The capability of antioxidant enzyme systems to recover from the Cr 6+ -induced damage was strong in G. rarus juveniles after Cr 6+ was removed from the water. Copyright © 2017 Elsevier B.V.

Highlights: •TiO{sub 2} NPs cytotoxicity at low exposure levels (≤1 μg/mL) to freshwater algae. •ROS generation, NP adsorption and internalization contributors to toxicity. •Observational evidence of genotoxicity by nanoparticles in an algal cell. •Reduced bioavailability thus detoxification of NPs by microalgae. •Possible role of EPS in detoxification. -- Abstract: In the current study, two aspects concerning (i) the cytotoxicity potential of TiO{sub 2} nanoparticles (NPs) toward freshwater algal isolate Scenedesmus obliquus and (ii) the potential detoxification of NPs by the microalgae were assessed under light (UV-illumination) and dark conditions at low exposure levels (≤1 μg/mL), using sterile freshwater as the test medium. The statistically significant reduction in cell viability, increase in reactive oxygen species production and membrane permeability (light vs. dark) suggested photo-induced toxicity of TiO{sub 2} NPs. The electron micrographs demonstrated adsorption of the NPs onto the cell surface and substantiated their internalization/uptake. The fluorescence micrographs and the confocal laser scanning (CLSM) images suggested the absence of a definite/intact nucleus in the light treated cells pointing toward the probable genotoxic effects of NPs. In a separate three cycle experiment, a continuous decrease in the cytotoxicity was observed, whereas, at the end of each cycle only fresh algae were added to the supernatant containing NPs from the previous cycle. The decreasing concentrations of the NPs in the subsequent cycles owing to agglomeration–sedimentation processes exacerbated by the algal interactions played a crucial role in the detoxification. In addition, the exo-polymeric substances produced by the cells could have rendered the available NPs less reactive, thereby, enhancing the detoxification effects.

The extensive use of rubber products, mainly tires, and the difficulties to recycle those products, has resulted in world wide environmental problems. Microbial devulcanisation is a promising way to increase the recycling of rubber materials. One obstacle is that several microorganisms tested for devulcanisation are sensitive to rubber additives. A way to overcome this might be to detoxify the rubber material with fungi prior to the devulcanisation. In this study, 15 species of white-rot and brown-rot fungi have been screened with regard to their capacity to degrade an aromatic model compound in the presence of ground waste tire rubber. The most effective fungus, Resinicium bicolor, was used for detoxification of rubber material. Increase in growth of the desulfurising bacterium Thiobacillus ferrooxidans in presence of the rubber treated with Resinicium bicolor compared to untreated rubber demonstrated that detoxification with fungi is possible.

Although risk factors for medication-overuse headache have been identified within the general population, most studies have neglected clinical samples. The present study examined the relative and combined associations of these factors with medication-overuse headache in a sample of US adults seeking treatment for primary headache disorders. Treatment-seeking headache patients provided data on demographics, headache variables, psychiatric variables, use of headache medications, and use of other prescription medications and substances. A classification tree selection strategy was utilized within this cross-sectional study to differentiate between those with and without medication-overuse headache, and a final multivariable model assessed their combined utility. Forty-three of 164 participants (26.2%) met diagnostic criteria for medication-overuse headache. Relative to non-medication-overuse headache participants, participants with medication-overuse headache reported greater headache-related disability (odds ratio = 1.09, 95% confidence interval = 1.01-1.18), escape and avoidance responses indicative of fear of pain (odds ratio = 1.07, 95% confidence interval = 1.00-1.15), and use of combination medications for headache (odds ratio = 3.10, 95% confidence interval = 1.51-6.36). The final multivariable model differentiated well between the 2 groups (area under the receiver operating characteristic curve = .78; 95% confidence interval = .71-.86). Items that assess headache-related disability, use of combination medications, and fear of pain help identify patients who are currently overusing acute headache medications and may serve as indicators of treatment progress. Future studies should apply similar analytic approaches longitudinally to identify headache sufferers at risk for medication-overuse headache prior to headache progression. © 2018 American Headache Society.

Fermentation of lignocellulosic hydrolysates: Inhibition and detoxification

Energy Technology Data Exchange (ETDEWEB)

Palmqvist, E.

1998-02-01

The ethanol yield and productivity obtained during fermentation of lignocellulosic hydrolysates is decreased due to the presence of inhibiting compounds, such as weak acids, furans and phenolic compounds produced during hydrolysis. Evaluation of the effect of various biological, physical and chemical detoxification treatments by fermentation assays using Saccharomyces cerevisiae was used to characterise inhibitors. Inhibition of fermentation was decreased after removal of the non-volatile compounds, pre-fermentation by the filamentous fungus Trichoderma reesei, treatment with the lignolytic enzyme laccase, extraction with ether, and treatment with alkali. Yeast growth in lignocellulosic hydrolysates was inhibited below a certain fermentation pH, most likely due to high concentrations of undissociated weak acids. The effect of individual compounds were studied in model fermentations. Furfural is reduced to furfuryl alcohol by yeast dehydrogenases, thereby affecting the intracellular redox balance. As a result, acetaldehyde accumulated during furfural reduction, which most likely contributed to inhibition of growth. Acetic acid (10 g 1{sup -1}) and furfural (3 g 1{sup -1}) interacted antagonistically causing decreased specific growth rate, whereas no significant individual or interaction effects were detected by the lignin-derived compound 4-hydroxybenzoic acid (2 g 1{sup -1}). By maintaining a high cell mass density in the fermentor, the process was less sensitive to inhibitors affecting growth and to fluctuations in fermentation pH, and in addition the depletion rate of bioconvertible inhibitors was increased. A theoretical ethanol yield and high productivity was obtained in continuous fermentation of spruce hydrolysate when the cell mass concentration was maintained at a high level by applying cell recirculation 164 refs, 16 figs, 5 tabs

2016-09-01

YbaO is an uncharacterized AsnC-family transcription factor of Escherichia coli. In both Salmonella enterica and Pantoea ananatis, YbaO homologues were identified to regulate the adjacent gene encoding cysteine desulfhydrase for detoxification of cysteine. Using the genomic SELEX (systematic evolution of ligands by exponential enrichment) screening system, we identified the yhaOM operon, located far from the ybaO gene on the E. coli genome, as a single regulatory target of YbaO. In both gel shift assay in vitro and reporter and Northern blot assays in vivo, YbaO was found to regulate the yhaOM promoter. The growth of mutants lacking either ybaO or its targets yhaOM was delayed in the presence of cysteine, indicating involvement of these genes in cysteine detoxification. In the major pathway of cysteine degradation, hydrogen sulfide is produced in wild-type E. coli, but its production was not observed in each of the ybaO, yhaO and yhaM mutants. The yhaOM promoter was activated in the presence of cysteine, implying the role of cysteine in activation of YbaO. Taken together, we propose that YbaO is the cysteine-sensing transcriptional activator of the yhaOM operon, which is involved in the detoxification of cysteine. We then propose the naming of ybaO as decR (regulator of detoxification of cysteine).

Full Text Available Elizabeth B Stuyt,1 Claudia A Voyles2 1Department of Psychiatry, University of Colorado Health Sciences Center, Pueblo, CO, 2Department of Clinical Studies, AOMA Graduate School of Integrative Medicine, Austin, TX, USA Abstract: The National Acupuncture Detoxification Association (NADA-standardized 3- to 5-point ear acupuncture protocol, born of a community-minded response to turbulent times not unlike today, has evolved into the most widely implemented acupuncture-assisted protocol, not only for substance abuse, but also for broad behavioral health applications. This evolution happened despite inconsistent research support. This review highlights the history of the protocol and the research that followed its development. Promising, early randomized-controlled trials were followed by a mixed field of positive and negative studies that may serve as a whole to prove that NADA, despite its apparent simplicity, is neither a reductive nor an independent treatment, and the need to refine the research approaches. Particularly focusing on the last decade and its array of trials that elucidate aspects of NADA application and effects, the authors recommend that, going forward, research continues to explore the comparison of the NADA protocol added to accepted treatments to those treatments alone, recognizing that it is not a stand-alone procedure but a psychosocial intervention that affects the whole person and can augment outcomes from other treatment modalities.

The aim of the present work was to investigate whether a detoxification method already in use during waste water treatment could be functional also for ethanol production based on lignocellulosic substrates. Chemical conditioning of spruce hydrolysate with hydrogen peroxide (H₂O₂) and ferrous sulfate (FeSO₄) was shown to be an efficient strategy to remove significant amounts of inhibitory compounds and, simultaneously, to enhance the enzymatic hydrolysis and fermentability of the substrates. Without treatment, the hydrolysates were hardly fermentable with maximum ethanol concentration below 0.4 g/l. In contrast, treatment by 2.5 mM FeSO₄ and 150 mM H₂O₂ yielded a maximum ethanol concentration of 8.3 g/l. Copyright © 2014 Elsevier Ltd. All rights reserved.

The goal of the study was to determine the long-term prevalence of combat-related treatment seeking and posttraumatic stress disorder (PTSD) in Israel's veterans deployed to the Second Lebanon War (2006) and "Operation Cast Lead" in the Gaza Strip (2009). The prevalence of treatment seeking and DSM-IV-TR diagnoses among Israel Defense Force (IDF) veterans was assessed using seven and five year's surveillance and records. The whereabouts and combat exposure of veterans during the war was determined based on the IDF's Operations Directorate records. Overall prevalence of treatment seeking was 1.32% and 0.38% in the Second Lebanon War and "Operation Cast Lead", respectively. The prevalence of treatment-seeking veterans from the Second Lebanon War and in "Operation Cast Lead" was significantly higher in soldiers deployed to high combat-exposure zones (2.19% and 3.1%, respectively), relative to low combat-exposure zones (0.24% and 0.06%, respectively), and relative to soldiers deployed elsewhere (0.26% and 0.02%, respectively). PTSD prevalence was similar among treatment-seeking veterans deployed in high combat-exposure zones in both combats. There is a gap of anywhere between 3% and 11% between treatment seeking by IDF veterans following war deployment and the actual prevalence of PTSD in this soldier population.

Weight Management Preferences in a Non-Treatment Seeking Sample

Full Text Available Background: Obesity is a serious public health issue in the United States, with the CDC reporting that most adult Americans are now either overweight or obese. Little is known about the comparative acceptability of available weight management approaches in non-treatment seeking samples. Method: This report presents preliminary survey data collected from an online sample on weight management preferences for 8 different weight management strategies including a proposed incentive-based program. Participants were 72 individuals (15 men, 55 women and 2 transgendered individuals who self-re-ported being overweight or obese, or who currently self-reported a normal weight but had attempted to lose weight in the past. Results: ANOVA and Pair-wise comparison indicated clear preferences for certain treatments over others in the full sample; most notably, the most popular option in our sample for managing weight was to diet and exercise without professional assistance. Several differences in preference between the three weight groups were also observed. Conclusions: Dieting and exercising without any professional assistance is the most highly endorsed weight management option among all groups. Overweight and obese individuals may find self-management strategies for weight loss less attractive than normal weight individuals, but still prefer it to other alternatives. This has implications for the development and dissemination of empirically based self-management strategies for weight.

Full Text Available Xylitol fermentation production from corncob acid hydrolysate has become an attractive and promising process. However, corncob acid hydrolysate cannot be directly used as fermentation substrate owing to various inhibitors. In this work, soaking in aqueous ammonia (SAA pretreatment was employed to reduce the inhibitors in acid hydrolysate. After detoxification, the corncob acid hydrolysate was fermented by immobilized Candida tropicalis cell to produce xylitol. Results revealed that SAA pretreatment showed high delignification and efficient removal of acetyl group compounds without effect on cellulose and xylan content. Acetic acid was completely removed, and the content of phenolic compounds was reduced by 80%. Furthermore, kinetic behaviors of xylitol production by immobilized C. tropicalis cell were elucidated from corncob acid hydrolysate detoxified with SAA pretreatment and two-step adsorption method, respectively. The immobilized C. tropicalis cell showed higher productivity efficiency using the corncob acid hydrolysate as fermentation substrate after detoxification with SAA pretreatment than by two-step adsorption method in the five successive batch fermentation rounds. After the fifth round fermentation, about 60 g xylitol/L fermentation substrate was obtained for SAA pretreatment detoxification, while about 30 g xylitol/L fermentation substrate was obtained for two-step adsorption detoxification.

This study evaluated relations between sexual sensation seeking, co-occurring sex and alcohol use, and sexual risk behaviors (eg, unprotected intercourse and multiple sex partners) among adolescents receiving treatment for substance abuse problems. The ethnically diverse sample included 394 adolescents recruited from outpatient treatment (280 males; Mage  = 16.33 years, SDage  = 1.15). Structural equation modeling (SEM) was used to test direct and indirect paths between sexual sensation seeking and sexual risk behaviors via the frequency of co-occurring sex and alcohol use. Conditional indirect effects by gender were also tested. Analyses identified significant effects of sexual sensation seeking on co-occurring sex and alcohol use and sexual risk behaviors. The path from co-occurring sex and alcohol use to unprotected intercourse was significantly stronger among adolescent girls, suggesting a mediation effect moderated by gender. No gender difference was found for the indirect path from sexual sensation seeking and number of past year sexual partners via co-occurring sex and alcohol use. Selected prevention efforts are needed to promote HIV risk reduction among adolescents in substance abuse treatment. The documented conditional indirect effect for unprotected intercourse suggests that HIV prevention programs should pay special attention to gender-specific patterns of alcohol use and sexual risk behavior when tailoring program content.

The Y-12 Sludge Detoxification Demonstration was conducted in late 1988 at the Oak Ridge Gaseous Diffusion Plant (subsequently renamed the K-25 Site). The erstwhile Waste Management Technology Center (WMTC) managed the conduct of this waste treatment technology to assist the US Department of Energy/Oak Ridge Operations (DOE/ORO) in implementing the DOE Model. This demonstration was the first project selected by the Hazardous Waste Remedial Actions Program (HAZWRAP)(and funded by DOE) in which a private-sector vendor was contracted to demonstrate an innovative treatment process for treating some of the Oak Ridge Site's radioactive mixed wastes to enable their environmentally compliant disposal. Chem-Nuclear Systems, Inc. (CNSI) was the private-sector vendor selected to demonstrate its X*TRAX trademark process. Briefly, the X*TRAX trademark process consisted of thermally treating the sludge in an inert atmosphere (to remove the volatile components) to yield a dry residue (containing the nonvolatilized sludge components) and condensed liquids. The dry residue can then be immobilized in cementitious matrix for delisting and disposal in an industrial landfill; the condensed liquids can be disposed in, for example, an incinerator

Full Text Available Metazoans protect themselves from environmental toxins and virulent pathogens through detoxification and immune responses. We previously identified a small molecule xenobiotic toxin that extends survival of Caenorhabditis elegans infected with human bacterial pathogens by activating the conserved p38 MAP kinase PMK-1 host defense pathway. Here we investigate the cellular mechanisms that couple activation of a detoxification response to innate immunity. From an RNAi screen of 1,420 genes expressed in the C. elegans intestine, we identified the conserved Mediator subunit MDT-15/MED15 and 28 other gene inactivations that abrogate the induction of PMK-1-dependent immune effectors by this small molecule. We demonstrate that MDT-15/MED15 is required for the xenobiotic-induced expression of p38 MAP kinase PMK-1-dependent immune genes and protection from Pseudomonas aeruginosa infection. We also show that MDT-15 controls the induction of detoxification genes and functions to protect the host from bacteria-derived phenazine toxins. These data define a central role for MDT-15/MED15 in the coordination of xenobiotic detoxification and innate immune responses.

2014-01-01

Individuals with substance use disorders are more likely to have antisocial and borderline personality disorder than non-substance abusers. Recently, research has examined the relations between early maladaptive schemas and personality disorders, as early maladaptive schemas are believed to underlie personality disorders. However, there is a dearth of research on the relations between early maladaptive schemas and personality disorders among individuals seeking treatment for substance abuse. The current study examined the relations among early maladaptive schemas and antisocial and borderline personality within in a sample of men seeking substance abuse treatment (n = 98). Results demonstrated that early maladaptive schema domains were associated with antisocial and borderline personality symptoms. Implications of these findings for substance use treatment and research are discussed. PMID:23650153

Contextual factors associated with treatment-seeking and higher-risk sexual behaviour in Botswana among men with symptoms of sexually transmitted infections.

2007-11-01

This study investigates contextual factors associated with treatment-seeking behaviour and higher-risk sexual conduct of men symptomatic of sexually transmitted infections (STIs) in Botswana. Data were drawn from a randomly selected, nationally representative sample of 8 222 men, aged 15-64 years, who had reported having symptoms suggestive of an STI during the previous twelve months. Higher-risk behaviour continues to sustain the HIV epidemic in Botswana. At the heart of Botswana's epidemic lies men's reluctance to seek medical treatment, engaging in unprotected sex, and having sex with multiple partners while symptomatic of an STI. The odds of engaging in unprotected sex while symptomatic of an STI were significantly higher among teenage males and males in urban households. For every year's increase in the age difference between partners there was a 28% increase in the odds of the male having had unprotected sex. Being married and having had more than one sexual partner in the last year multiplied the odds of having unprotected sex while symptomatic of an STI by three times. The longer an infected man remained with symptoms before seeking help, the more likely it was to have unprotected sex while infected and the more likely to seek treatment from a traditional healer. Notably, having sought medical treatment from hospitals, clinics and health workers, as opposed to consulting traditional healers, significantly reduced the odds of having had unprotected sex while infected with an STI by 48%. The results indicate the need to encourage men to utilise public healthcare services. The public health sector in Botswana needs to provide healthcare services that are user-friendly for men. Increasing the number of treatment sites may also contribute to preventing onward transmission of STIs. Special attention needs to be paid to boys' socialisation towards gender norms, and men are to be encouraged to play a responsible role in HIV prevention.

Pharmaceutically active compounds (PhACs) have been recently shown to exert phytotoxic effects. The present study explores the uptake, systemic translocation, and abiotic stress responses and detoxification mechanisms induced by the exposure of alfalfa plants grown in sand under greenhouse conditions to four common, individually applied PhACs (10 μg L −1 ) (diclofenac, sulfamethoxazole, trimethoprim, 17a-ethinylestradiol) and their mixture. Stress physiology markers (lipid peroxidation, proline, H 2 O 2 and NO content, antioxidant activity assays) and gene expression levels of key plant detoxification components (including glutathione S-transferases, GST7, GST17; superoxide dismutases, CuZnSOD, FeSOD; proton pump, H + -ATP, and cytochrome c oxidase, CytcOx), were evaluated. PhACs were detected in significantly higher concentrations in roots compared with leaves. Stress related effects, manifested via membrane lipid peroxidation and oxidative burst, were local (roots) rather than systemic (leaves), and exacerbated when the tested PhACs were applied in mixture. Systemic accumulation of H 2 O 2 in leaves suggests its involvement in signal transduction and detoxification responses. Increased antioxidant enzymatic activities, as well as upregulated transcript levels of GST7, GST17, H + -ATPase and CytcOx, propose their role in the detoxification of the selected PhACs in plants. The current findings provide novel biochemical and molecular evidence highlighting the studied PhACs as an emerging abiotic stress factor, and point the need for further research on wastewater flows under natural agricultural environments. - Highlights: • PhACs were detected in higher concentrations in roots compared with leaves. • Stress effects were local and exacerbated when PhACs were applied in mixture. • H 2 O 2 may be involved in signal transduction and detoxification responses. • GSTs, H + -ATPase and CytcOx contribute to the detoxification of PhACs in plants. • Results

Cannabis continues to rise in popularity as the perception of its harmfulness decreases and evidence of its deleterious developmental effect increases. While internalizing distress and suicide risk have been linked with cannabis use problems [DSM-5 cannabis use disorder (CUD); DSM-IV cannabis abuse and dependence] it remains unclear how this association varies over the course of development in treatment-seeking men and women. The current study utilized the National Drug Abuse Treatment Clinical Trials Network (NIDA CTN) to conduct a cross-sectional comparison of internalizing distress and suicide risk among men (n=437) and women (n=163) spanning ages 18-50 who met DSM-5 criteria for CUD. Interactions between gender and developmental stage (i.e., late adolescence, early adulthood, and middle adulthood) were observed for suicide risk and anxiety but not depression problems. Specifically, women seeking CUD treatment in late adolescence and middle adulthood exhibited significantly higher rates of anxiety and suicide risk compared to men seeking treatment during the same developmental stages. Internalizing distress and suicide risk did not differ between treatment-seeking men and women in the early adult stage. Overall, results suggest that the structure of risk for CUD may differ in men and women across the lifespan and that women presenting for CUD treatment during late adolescence and middle adulthood may uniquely benefit from intervention designed to address these elevations in anxiety and suicide risk.

Metal accumulation and detoxification mechanisms in mycorrhizal Betula pubescens.

Fernández-Fuego, D; Bertrand, A; González, A

2017-12-01

Metal detoxification in plants is a complex process that involves different mechanisms, such as the retention of metals to the cell wall and their chelation and subsequent compartmentalization in plant vacuoles. In order to identify the mechanisms involved in metal accumulation and tolerance in Betula pubescens, as well as the role of mycorrhization in these processes, mycorrhizal and non-mycorrhizal plants were grown in two industrial soils with contrasting concentrations of heavy metals. Mycorrhization increased metal uptake at low metal concentrations in the soil and reduced it at high metal concentrations, which led to an enhanced growth and biomass production of the host when growing in the most polluted soil. Our results suggest that the sequestration on the cell wall is the main detoxification mechanism in white birch exposed to acute chronic metal-stress, while phytochelatins play a role mitigating metal toxicity inside the cells. Given its high Mn and Zn root-to-shoot translocation rate, Betula pubescens is a very promising species for the phytoremediation of soils polluted with these metals. Copyright © 2017 Elsevier Ltd.

Full Text Available Abstract Background Data on sociological and behavioural aspects of malaria, which is essential for an evidence-based design of prevention and control programmes, is lacking in Bangladesh. This paper attempts to fill this knowledge gap by using data from a population-based prevalence survey conducted during July to November 2007, in 13 endemic districts of Bangladesh. Methods A two-stage cluster sampling technique was used to select study respondents randomly from 30 mauzas in each district for the socio-behavioural inquiry (n = 9,750. A pre-tested, semi-structured questionnaire was used to collect data in face-to-face interview by trained interviewers, after obtaining informed consent. Results The overall malaria prevalence rate in the 13 endemic districts was found to be 3.1% by the Rapid Diagnostic Test 'FalciVax' (P. falciparum 2.73%, P. vivax 0.16% and mixed infection 0.19%, with highest concentration in the three hill districts (11%. Findings revealed superficial knowledge on malaria transmission, prevention and treatment by the respondents. Poverty and level of schooling were found as important determinants of malaria knowledge and practices. Allopathic treatment was uniformly advocated, but the 'know-do' gap became especially evident when in practice majority of the ill persons either did not seek any treatment (31% or practiced self-treatment (12%. Of those who sought treatment, the majority went to the village doctors and drugstore salespeople (around 40%. Also, there was a delay beyond twenty-four hours in beginning treatment of malaria-like fever in more than half of the instances. In the survey, gender divide in knowledge and health-seeking behaviour was observed disfavouring women. There was also a geographical divide between the high endemic south-eastern area and the low-endemicnorth-eastern area, the former being disadvantaged with respect to different aspects of malaria studied. Conclusion The respondents in this study lacked

Some plants used in Unani system of medicine are toxic, even deadly poisonous. The drugs having such plants as their components are detoxified before they are dispensed to the patients. One such drug, capsule Hudar, has Strychnos nux-vomica L. (Azraqi) seeds as one of its components and is very effectively used to elevate blood pressure. Ancient manuscripts describe many methods of its detoxification. It has been found that the detoxification processes studied reduce the strychnine content, as determined either by using uv-vis spectrophotometer or HPLC, present in Strychnos nux vomica seeds which is responsible for Strychnos nux vomica toxicity. The decrease in strychnine amount was best when the seeds were immersed for detoxification in excess of water for 5 days, in milk for 2 days followed by their boiling in milk. Strychnine in small amounts has been reported to give subjective feeling of stimulation.

Full Text Available Abstract Background Population movements along the Thailand-Cambodia border, particularly among highly mobile and hard-to-access migrant groups from Cambodia and Myanmar, are assumed to play a key role in the spread of artemisinin resistance. Data on treatment-seeking behaviours, knowledge and perceptions about malaria, and use of preventive measures is lacking as characteristics of this population prevent them from being represented in routine surveillance and the lack of a sampling frame makes reliable surveys challenging. Methods A survey of migrant populations from Cambodia and Myanmar was implemented in five selected rural locations in Thailand along the Thai-Cambodian border using respondent driven sampling (RDS to determine demographic characteristics of the population, migratory patterns, knowledge about malaria, and health-care -seeking behaviours. Results The majority of migrants from Myanmar are long-term residents (98% with no plans to move back to Myanmar, understand spoken Thai (77% and can therefore benefit from health messages in Thai, have Thai health insurance (99% and accessed public health services in Thailand (63% for their last illness. In comparison, the majority of Cambodian migrants are short-term (72%. Of the short-term Cambodian migrants, 92% work in agriculture, 18% speak Thai, 3.4% have Thai health insurance, and the majority returned to Cambodia for treatment (45%, self-treated (11%, or did not seek treatment for their last illness (27%. Conclusion Most highly mobile migrants along the Thai-Cambodia border are not accessing health messages or health treatment in Thailand, increasing their risk of malaria and facilitating the spread of potentially resistant Plasmodium falciparum as they return to Cambodia to seek treatment. Reaching out to highly mobile migrants with health messaging they can understand and malaria diagnosis and treatment services they can access is imperative in the effort to contain the spread of

Little is known about the intergenerational and cross-cultural differences in emotional wellbeing and acceptability of psychological treatments for Arab Australians. To contribute to the emerging data about the mental health status and needs of Arab Australians. An Internet survey examined psychological distress and functional impairment as measured by the Kessler 10 Item scale (K-10) and the Sheehan Disability Scale (SDS) among Arab Australians. Additional questions enquired about their help-seeking behaviours, barriers to accessing psychological treatments and preferences for delivery of psychological treatments. A total of 252 participants were recruited through public talks, media and online promotions. Forty-three percent of the respondents reported moderate-to-severe functional impairment (M = 9.5; standard deviation (SD) = 1.8), 32% reported high psychological distress (M = 28.5; SD = 5.4) and 30% were born overseas. First-generation Arab Australians experiencing high psychological distress (i.e. K-10 ≥ 22), reported a greater preference for Internet-delivered treatment when compared to their second-generation counterparts. Only 18% of the sample reported seeking help from a mental health professional in the past year. The significant barriers reported by respondents with high psychological distress were poor mental health literacy, lack of time and stigma. Respondents preferred face-to-face (90%) over Internet-delivered treatment (55%). Finally, Arab Australians experienced higher psychological distress and underutilised mental health services when compared to the Australian population. Targeted public health campaigns that make culturally relevant interventions such as modifying existing Internet-delivered treatment for Arab Australians may reduce barriers and increase treatment options for this population. © The Author(s) 2014.

The objective of this paper is to perform a cross-cultural comparison of gambling disorder (GD) due to electronic gaming machines (EGM), a form of gambling that may have a high addictive potential. Our goal is to investigate two treatment-seeking samples of adults collected in Brazil and the United States, countries with different socio-cultural backgrounds. This comparison may lead to a better understanding of cultural influences on GD. The total studied sample involved 733 treatment-seeking subjects: 353 men and 380 women (average age=45.80, standard deviation ±10.9). The Brazilian sample had 517 individuals and the American sample 216. Subjects were recruited by analogous strategies. We found that the Brazilian sample was younger, predominantly male, less likely to be Caucasian, more likely to be partnered, tended to have a faster progression from recreational gambling to GD, and were more likely to endorse chasing losses. This study demonstrated that there are significant differences between treatment-seeking samples of adults presenting GD due to EGM in Brazil and in the United States. These findings suggest that cultural aspects may have a relevant role in GD due to EGM. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Weight Loss Expectations and Attrition in Treatment-Seeking Obese Women

Full Text Available Objective: The analysis of the relation between weight loss goals and attrition in the treatment of obesity has produced conflicting results. The aim of the present study was to investigate the role of weight loss goals on attrition in a cohort of obese women seeking treatment at 8 Italian medical centres. Methods: 634 women with obesity, consecutively enrolled in weight loss programmes, were included in the study. Weight loss goals were evaluated with the Goals and Relative Weights Questionnaire (GRWQ, reporting a sequence of unrealistic (‘dream' and ‘happy' and more realistic (‘acceptable' and ‘disappointing' weight loss goals. Attrition was assessed at 12 months on the basis of patients' medical records. Results: At 12 months, 205/634 patients (32.3% had interrupted their programme and were lost to follow-up. After adjustment for age, baseline weight, education and employment status, attrition was significantly associated with higher percent acceptable and disappointing weight loss targets, not with dream and happy weight loss. Conclusion: In ‘real world' clinical settings, only realistic expectations might favour attrition whenever too challenging, whereas unrealistic weight loss goals have no effect. Future studies should assess the effect of interventions aimed at coping with too challenging weight goals on attrition.

Pollinators, including honey bees, routinely encounter potentially harmful microorganisms and phytochemicals during foraging. However, the mechanisms by which honey bees manage these potential threats are poorly understood. In this study, we examine the expression of antimicrobial, immune and detoxification genes in Apis mellifera and compare between forager and nurse bees using tissue-specific RNA-seq and qPCR. Our analysis revealed extensive tissue-specific expression of antimicrobial, immune signaling, and detoxification genes. Variation in gene expression between worker stages was pronounced in the mandibular and hypopharyngeal gland (HPG), where foragers were enriched in transcripts that encode antimicrobial peptides (AMPs) and immune response. Additionally, forager HPGs and mandibular glands were enriched in transcripts encoding detoxification enzymes, including some associated with xenobiotic metabolism. Using qPCR on an independent dataset, we verified differential expression of three AMP and three P450 genes between foragers and nurses. High expression of AMP genes in nectar-processing tissues suggests that these peptides may contribute to antimicrobial properties of honey or to honey bee defense against environmentally-acquired microorganisms. Together, these results suggest that worker role and tissue-specific expression of AMPs, and immune and detoxification enzymes may contribute to defense against microorganisms and xenobiotic compounds acquired while foraging.

For this population, we identified all contacts with GPs between 1996 and 2011 to quantify the sex differences in treatment-seeking behavior within the 3-year periods before and after hospitalization, and to estimate the impact of the civil and educational status on the sex...... differentials in treatment-seeking. We found women having consistently more GP contacts across all ages, but a narrowing of the treatment-seeking behavior shortly before and after admission to hospital. We moreover found a gradient of the educational and the marital status, suggesting that groups with higher...

This study focuses on differential molecular mechanisms of antioxidant and detoxification systems in rice plants under two different types of photodynamic stress imposed by porphyrin deregulators, 5-aminolevulinic acid (ALA) and oxyfluorfen (OF). The ALA-treated plants with white necrosis exhibited a greater decrease in photochemical quantum efficiency, F{sub v}/F{sub m}, as well as a greater increase in activity of superoxide dismutase, compared to the OF-treated plants. By contrast, the brown necrosis in OF-treated plants resulted in not only more widely dispersed H{sub 2}O{sub 2} production and greater increases in H{sub 2}O{sub 2}-decomposing enzymes, catalase and peroxidase, but also lower ascorbate redox state. In addition, ALA- and OF-treated plants markedly up-regulated transcript levels of genes involved in detoxification processes including transport and movement, cellular homeostasis, and xenobiotic conjugation, with prominent up-regulation of serine/threonine kinase and chaperone only in ALA-treated plants. Our results demonstrate that different photodynamic stress imposed by ALA and OF developed differential actions of antioxidant enzymes and detoxification. Particularly, detoxification system may play potential roles in plant protection against photodynamic stress imposed by porphyrin deregulators, thereby contributing to alleviation of photodynamic damage. - Highlights: • We employ two different types of photodynamic stress, white and brown necrosis. • We examine molecular mechanisms of antioxidative and detoxification systems. • ALA and OF develop differential actions of antioxidant and detoxification systems. • Coordinated mechanism of antioxidants and detoxification works against toxic ROS. • Detoxification system plays critical roles in protection against photodynamic stress.

Full Text Available Background: About 8 percent of Iranian adult population are illicit drug abusers. Affected persons grow more each day. Ominous consequences such as divorce, prostitution, murder and other crimes and infectious diseases such as AIDS and hepatitis take place following drug abuse, as well as a loss equall to 29% of national income for our country. Traditional treatment methods wasted too much time and cost. professional inpatient clinics are not adequate for admission of all care seekers. Rapid detoxification methods are supposed to be better alternatives. Materials and Methods: 140 male drug abusers in two matched groups were assessed from March to September, 2005. They used heroin or opium. Both groups were scheduled for detoxification and were closely observed for 3 months thereafter. First group received Clonidine, Benzodiazepine and Naltrexone besides symptom relieving modalities in first 4 days of treatment. Naltrexone was continued in maintenance dose for one month. Second group received Methadone for one month. Results: Clients age was between 18 to 73 years, with mean age 34 years old. Their intelligence quotients were above the lower limit of normal range. There was no significant difference according to these parameters between two groups. Success rate in rapid detoxification group was 55 % and in Methadone group was 50 %. Relapse in rapid detoxification method occurred less frequent and slower (45 % vs. 50%. In Naltrexone group, better success rate was due to less duration of drug abuse and heroin dependency. In Methadone group, therapy had better results in patients with longer drug abuse history and opium addiction. There was no significant difference between success rate and either drug kind or job, marital status or education level. The most serious adverse effect in both groups was hypotension (10% in Naltrexone and 5 % in Methadone groups.

Although many postgraduate psychology programs address students' mental health, there are compelling indications that earlier, undergraduate, interventions may be optimal. We investigated specific attitudes that predict students' intentions to seek treatment for psychological distress to inform targeted interventions. Psychology students (N = 289; mean age = 19.75 years) were surveyed about attitudes and intentions to seek treatment for stress, anxiety, or depression. Less than one quarter of students reported that they would be likely to seek treatment should they develop psychological distress. Attitudes that predicted help-seeking intentions related to recognition of symptoms and the benefits of professional help, and openness to treatment for emotional problems. The current study identified specific attitudes which predict help-seeking intentions in psychology students. These attitudes could be strengthened in undergraduate educational interventions promoting well-being and appropriate treatment uptake among psychology students. © 2013 Wiley Periodicals, Inc.

Physical activity has been found to alleviate mental health problems and could be beneficial for at-risk populations, such as transgender people. This study had 3 aims. First, to explore the amount of physical activity that treatment-seeking transgender people engage in and to compare this to matched cisgender people. Second, to determine whether there was a difference in physical activity depending on cross-sex hormone use. Third, to determine factors that predict physical activity among treatment-seeking transgender people. Transgender (n = 360) and cisgender people (n = 314) were recruited from the United Kingdom. Participants were asked to complete questionnaires about physical activity, symptoms of anxiety and depression, self-esteem, body satisfaction, and transphobia. Transgender people engaged in less physical activity than cisgender people. Transgender people who were on cross-sex hormone treatment engaged in more physical activity than transgender people who were not. In transgender people on cross-sex hormones, high body satisfaction was the best statistical predictor of physical activity, whereas high self-esteem was the best statistical predictor in people who were not. Transgender people are less active than cisgender people. Cross-sex hormone treatment appears to be able to indirectly increase physical activity within this population, which may be beneficial for mental well-being.

Ursodeoxycholic acid (UDCA) exerts anticholestatic, antifibrotic and antiproliferative effects in primary biliary cirrhosis (PBC) via mechanisms not yet fully understood. Its adequate biliary enrichment is considered mandatory for therapeutic efficacy. However, precise determination of biliary enrichment of UDCA is not possible in clinical practice. Therefore, we investigated (i) the relationship between biliary enrichment and plasma pharmacokinetics of UDCA, (ii) the effect of UDCA on plasma and biliary bile acid composition and conjugation patterns, and (iii) on the intestinal detoxification machinery in patients with PBC and healthy controls. In 11 PBC patients and 11 matched healthy subjects, cystic bile and duodenal tissue were collected before and after 3 weeks of administration of UDCA (15 mg/kg/day). Extensive pharmacokinetic profiling of bile acids was performed. The effect of UDCA on the intestinal detoxification machinery was studied by quantitative PCR and Western blotting. The relative fraction of UDCA and its conjugates in plasma at trough level[x] correlated with their biliary enrichment[y] (r=0.73, p=0.0001, y=3.65+0.49x). Taurine conjugates of the major hydrophobic bile acid, chenodeoxycholic acid, were more prominent in bile of PBC patients than in that of healthy controls. Biliary bile acid conjugation patterns normalized after treatment with UDCA. UDCA induced duodenal expression of key export pumps, BCRP and P-glycoprotein. Biliary and trough plasma enrichment of UDCA are closely correlated in PBC and health. Taurine conjugation may represent an adaptive mechanism in PBC against chenodeoxycholic acid-mediated bile duct damage. UDCA may stabilize small intestinal detoxification by upregulation of efflux pumps. Copyright © 2012. Published by Elsevier B.V.

Graphene oxide (GO) and its functionalized systems have very unique structural advantages as excellent adsorbent or substrate material in the removal of organic contaminants. Herein, we reported a strategy to establish functionalized GO system (FGO) using amphiphilic molecules didodecyldimethylammonium bromide (DDAB) as a modifier for the detoxification of zearalenone (ZEN) from corn oil. The adsorption property for the removal of ZEN from edible corn oils under different experimental conditions such as pH, amphiphilic molecules, time and temperature was investigated in detail. The morphology structure, adsorption isotherm, adsorption kinetics and the recyclability of FGO systems have also been researched, systematically.

Full Text Available Immediate treatment of first-episode psychosis is essential in order to achieve a positive outcome. However, Indonesian psychiatric patients often delay accessing health services, the reason for which is not yet fully understood. The current study aimed to understand patterns of treatment seeking and to reveal determinants of the delay in accessing psychiatric care among first-time user psychotic patients. Qualitative interviews were conducted with sixteen family members who accompanied the patients to a psychiatric hospital. Many families expressed beliefs that mental illness appertains to village sickness and not hospital sickness; therefore, they usually take the patients to traditional or religious healers before taking them to a health professional. They also identified various factors that potentially delay accessing psychiatric treatment: low literacy and beliefs about the cause of the illness, stigmatisation, the role of extended family, financial problems, and long distance to the psychiatric hospital. On the other hand, the family mentioned various factors related to timely help seeking, including being a well-educated family, living closer to health facilities, previous experience of successful psychotic therapy, and having more positive symptoms of psychosis. The findings call for mental health awareness campaigns in the community.

Full Text Available ABSTRACT Relapse is highly prevalent after detoxification and depression. Due to the advantages of venlafaxine compared with other antidepressants, it is expected that venlafaxine administration may reduce relapse after detoxification and depression. This study aimed to evaluate the effects of venlafaxine on depression-induced relapse to morphine dependence after methadone detoxification. Eighty Sprague-Dawley rats were habituated and conditioned with morphine (10 mg/kg, S.C., for 4 days. After that, primary forced swimming and conditioned place preference (CPP were tested. They were followed by methadone (70 mg/kg/day, P.O., for 7 days administration, extinguishing, forced swimming stress (FSS and administration of venlafaxine (80 mg/kg/day, I.P., for 7 days. Finally same tests were performed. Administration of venlafaxine resulted in a decrement in final preference scores associated with a prime morphine injection (PMI compared to the primary scores in methadone treated (MTD+ animals. In a swimming test, venlafaxine increased the amount of final floating and decreased final activity scores compared with the primary scores after administration of methadone. Venlafaxine reduced locomotor activity in MTD+ animals in the final test with PMI. There was a positive correlation between the final activity and preference scores after PMI. In conclusion, venlafaxine improved anxiety and depression-induced relapse on methadone detoxified rats.

Full Text Available A differential approach to choosing the methods of extracorporeal detoxification in the complex treatment of abdominal sepsis in the context of endogenous intoxication in order to enhance the efficiency of medical measures was pathogeneti-cally substantiated. In 51 patients diagnosed as having abdominal sepsis, the latter was characterized as the endogenous intoxication syndrome in relation to the accumulation of low and medium molecular-weight substances (plasma and red blood cells in the body and their physiological elimination with urine. An original formula was used to calculate the integral marker – the endogenous intoxication index correlating with the routine severity rating scales APACHE II and SOFA and reflecting the severity of endotoxicosis. According to the values of the endogenous intoxication index and to the sum of scores by the APACHE II and SOFA scales, the patients were divided into 3 groups of the clinicopathogenetic types of endogenous intoxication. According to the type of endogenous intoxication, the authors proposed a differential approach to choosing the modes of efferent therapy for abdominal sepsis: high-volume plasmapheresis in the subcompensated type and prolonged venovenous hemofiltration, which improved the results of treatment and reduced mortality rates.

Background Attention-deficit/hyperactivity disorder (ADHD) is often comorbid with cocaine abuse. Controversy exists regarding long-term consequences of ADHD medications on cocaine abuse liability. Whereas childhood methylphenidate treatment may be preventative, methylphenidate in teens appears to further increase later cocaine abuse risk. In rodents, adolescent methylphenidate treatment further increases adult cocaine self-administration in the Spontaneously Hypertensive Rat (SHR) model of ADHD, whereas adolescent atomoxetine treatment does not. Effects of ADHD medications on cocaine cue reactivity, a critical component of addiction, are unknown. Methods To investigate this, SHR, Wistar-Kyoto (inbred control) and Wistar (outbred control) rats received therapeutically relevant doses of methylphenidate (1.5 mg/kg, oral) and atomoxetine (0.3 mg/kg, intraperitoneal), or respective vehicles from post-natal day 28–55. Cocaine seeking, reflecting cue reactivity, was measured in adulthood during self-administration maintenance and cue-induced reinstatement tests conducted under a second-order schedule. Results Compared to control strains, SHR earned more cocaine infusions, emitted more cocaine-seeking responses during maintenance and reinstatement testing, and required more sessions to reach the extinction criterion. Compared to vehicle, adolescent methylphenidate, but not atomoxetine, further increased cocaine intake during maintenance testing in SHR. Adolescent atomoxetine, but not methylphenidate, decreased cocaine seeking during reinstatement testing in SHR. Neither medication had effects on cocaine intake or cue reactivity in control strains. Conclusions The SHR successfully model ADHD and cocaine abuse comorbidity and show differential effects of adolescent ADHD medications on cocaine intake and cue reactivity during adulthood. Thus, SHR have heuristic value for assessing neurobiology underlying the ADHD phenotype and for evaluating pharmacotherapeutics for ADHD

Pica and rumination disorder (RD)-formerly classified within DSM-IV Feeding and Eating Disorders of Infancy or Early Childhood-are now classified within DSM-5 Feeding and Eating Disorders. Though pica and RD have been studied in select populations (e.g., pregnant women, intellectually disabled persons), their typical features and overall prevalence remain unknown. This study examined the clinical characteristics and frequency of DSM-5 pica and RD among individuals seeking treatment for eating disorders and obesity. We conducted structured interviews with adolescent and young adult females from a residential eating disorder center (N = 149), and adult males and females with overweight or obesity from an outpatient weight-loss clinic (N = 100). Several participants reported ingesting non-nutritive substances (e.g., ice) for weight-control purposes. However, only 1.3% (n = 2; 95% CI: .06% to 5.1%) at the residential eating disorder center and 0% at the weight-loss clinic met DSM-5 criteria for pica, consuming gum and plastic. Although no eating disorder participants were eligible for an RD diagnosis due to DSM-5 trumping rules, 7.4% (n = 11; 95% CI: 4.0% to 12.9%) endorsed rumination behavior under varying degrees of volitional control. At the weight-loss clinic, 2.0% (n = 2; 95% CI: 0.1% to 7.4%) had RD. DSM-5 pica and RD were rare in our sample of individuals seeking treatment for eating disorders and obesity, but related behaviors were more common. The wide range of pica and rumination presentations highlights the challenges of differential diagnosis with other forms of disordered eating. © 2014 Wiley Periodicals, Inc.

The objective of this study was to verify the effects of ethanol consumption and alcohol detoxification on the biomechanics, area and thickness of cortical and trabecular bone in rat femur. This was an experimental study in which 18 male Wistar rats were used, with 40 days of age, weighing 179 ± 2.5 g. The rats were divided into three groups (n=06): CT (control), AC (chronic alcoholic), DT (detoxification). After experimental procedures, the animals were euthanized by an overdose of the anesthetic and their femurs were collected for mechanical testing and histological processing. All animals did not present malnutrition or dehydration during experimentation period. Morphometric analysis of cortical and trabecular bones in rat femurs demonstrated that AC animals showed inferior dimensions and alcohol detoxification (DT) allowed an enhancement in area and thickness of cortical and trabecular bone. Material and structural properties data of AC group highlighted the harmful effects of ethanol on bone mechanical properties. The results of this study demonstrated that chronic alcoholic rats (AC) presented major bone damage in all analyzed variables. Those findings suggested that alcohol detoxification is highly suggested in pre-operative planning and this corroborates to the success of bone surgery and bone tissue repair.

The objectives of the present study were to estimate the psychiatric comorbidity of Taiwanese heroin users seeking treatment and to identify the gender differences in psychiatric comorbidity and drug use behavior. Subjects were interviewed using a structured questionnaire on drug use behavior and the Mini International Neuropsychiatric Interview for psychiatric disorders. Of the subjects, 58.5% of the male and 62.5% of the female subjects had at least one non-substance-use axis I psychiatric disorder or antisocial personality disorder. Compared to male subjects, female subjects were younger, were less educated, had higher rates of unemployment and had earlier onset of illicit drug use. Female subjects were 11-fold more likely than male subjects to exhibit suicidal behavior. Among heroin abusers in the present study, female subjects were more widely exposed to unfavorable social factors and had substantially higher incidence of suicidal behavior than male subjects. Drug treatment centers should be aware of these gender differences and pay particular attention to comorbid depressive disorders and suicidal behavior of female heroin abusers.

Full Text Available The purpose of this study was to evaluate the prevalence of EDs in women seeking treatment for infertility, and to better characterize their clinical profile.Sixty participants completed self-report measures that assessed EDs, desire for a child, body preoccupations, quality of life, anxiety and depression.Ten patients (17% met criteria for a past or current ED. We showed a significant association between greater body dissatisfaction and a more ambivalent desire for a child. Furthermore, an ED was associated with (i a lower quality of life, and (ii more anxiety disorders.Screening for a history of ED in infertile women is recommended to plan for adapted care regarding infertility but also regarding ED and psychiatric comorbidities. Therefore, the assessment has to take into account the desire for a child and the body satisfaction, that are essential parts of the ED process on the one hand and infertility process on the other. This could help with the infertility treatment and the prevention of negative maternal and fetal outcomes.

Cellulosic ethanol production from lignocellulosic biomass offers a sustainable solution for transition from fossil based fuels to renewable alternatives. However, a few long-standing technical challenges remain to be addressed in the development of an economically viable fermentation process from lignocellulose. Such challenges include the needs to improve yeast tolerance to toxic inhibitory compounds and to achieve high fermentation efficiency with minimum detoxification steps after a simple biomass pretreatment. Here we report an in-situ detoxification strategy by PEG exo-protection of an industrial dry yeast (starch-base). The exo-protected yeast cells displayed remarkably boosted vitality with high tolerance to toxic inhibitory compounds, and with largely improved ethanol productivity from crude hydrolysate derived from a pretreated lignocellulose. The PEG chemical exo-protection makes the industrial S. cerevisiae yeast directly applicable for the production of cellulosic ethanol with substantially improved productivity and yield, without of the need to use genetically modified microorganisms.

Kotze, Andrew C; Ruffell, Angela P; Ingham, Aaron B

2014-12-01

We used an enzyme induction approach to study the role of detoxification enzymes in the interaction of the anthelmintic compound naphthalophos with Haemonchus contortus larvae. Larvae were treated with the barbiturate phenobarbital, which is known to induce the activity of a number of detoxification enzymes in mammals and insects, including cytochromes P450 (CYPs), UDP-glucuronosyltransferases (UDPGTs), and glutathione (GSH) S-transferases (GSTs). Cotreatment of larvae with phenobarbital and naphthalophos resulted in a significant increase in the naphthalophos 50% inhibitory concentration (IC50) compared to treatment of larvae with the anthelmintic alone (up to a 28-fold increase). The phenobarbital-induced drug tolerance was reversed by cotreatment with the UDPGT inhibitors 5-nitrouracil, 4,6-dihydroxy-5-nitropyrimidine, probenecid, and sulfinpyrazone. Isobologram analysis of the interaction of 5-nitrouracil with naphthalophos in phenobarbital-treated larvae clearly showed the presence of strong synergism. The UDPGT inhibitors 5-nitrouracil, 4,6-dihydroxy-5-nitropyrimidine, and probenecid also showed synergistic effects with non-phenobarbital-treated worms (synergism ratio up to 3.2-fold). This study indicates that H. contortus larvae possess one or more UDPGT enzymes able to detoxify naphthalophos. In highlighting the protective role of this enzyme group, this study reveals the potential for UDPGT enzymes to act as a resistance mechanism that may develop under drug selection pressure in field isolates of this species. In addition, the data indicate the potential for a chemotherapeutic approach utilizing inhibitors of UDPGT enzymes as synergists to increase the activity of naphthalophos against parasitic worms and to combat detoxification-mediated drug resistance if it arises in the field.

Animal studies have demonstrated that chronic exposure to drugs of abuse impairs goal-directed control over action selection indexed by the outcome-devaluation and specific Pavlovian to instrumental transfer procedures, suggesting this impairment might underpin addiction. However, there is currently only weak evidence for impaired goal-directed control in human drug users. Two experiments were undertaken in which treatment-seeking drug users and non-matched normative reference samples (controls) completed outcome-devaluation and specific Pavlovian to instrumental transfer procedures notionally translatable to animal procedures (Experiment 2 used a more challenging biconditional schedule). The two experiments found significant outcome-devaluation and specific Pavlovian to instrumental transfer effects overall and there was no significant difference between groups in the magnitude of these effects. Moreover, Bayes factor supported the null hypothesis for these group comparisons. Although limited by non-matched group comparisons and small sample sizes, the two studies suggest that treatment-seeking drug users have intact goal-directed control over action selection, adding uncertainty to already mixed evidence concerning the role of habit learning in human drug dependence. Neuro-interventions might seek to tackle goal-directed drug-seeking rather than habit formation in drug users. This article is protected by copyright. All rights reserved.

Full Text Available Two strategies leading to enzyme saving during saccharification of pretreated lignocellulo-starch biomass (LCSB was investigated which included reducing enzyme dosage by varying their levels in enzyme cocktails and enhancing the fermentable sugar yield in enzyme-reduced systems using detoxification chemicals. Time course release of reducing sugars (RS during 24–120 h was significantly higher when an enzyme cocktail containing full dose of cellulase (16 FPU/g cellulose along with half dose each of xylanase (1.5 mg protein/g hemicelluloses and Stargen (12.5 μl/g biomass was used to saccharify conventional dilute sulphuric acid (DSA pretreated biomass compared to a parallel system where only one-fourth the dose of the latter two enzymes was used. The reduction in RS content in the 120 h saccharified mash to the extent of 3–4 g/L compared to the system saccharified with full complement of the three enzymes could be overcome considerably by supplementing the system (half dose of two enzymes with detoxification chemical mix incorporating Tween 20, PEG 4000 and sodium borohydride. Microwave (MW-assisted DSA pretreated biomass on saccharification with enzyme cocktail having full dose of cellulase and half dose of Stargen along with detoxification chemicals gave significantly higher RS yield than DSA pretreated system saccharified using three enzymes. The study showed that xylanase could be eliminated during saccharification of MW-assisted DSA pretreated biomass without affecting RS yield when detoxification chemicals were also supplemented. The Saccharification Efficiency and Overall Conversion Efficiency were also high for the MW-assisted DSA pretreated biomass. Since whole slurry saccharifcation of pretreated biomass is essential to conserve fermentable sugars in LCSB saccharification, detoxification of soluble inhibitors is equally important as channelling out of insoluble lignin remaining in the residue.

Tobacco and cannabis are frequently used in combination and cannabis co-use may lead to poor tobacco cessation outcomes. Therefore, it is important to explore if cannabis co-use is associated with a reduced likelihood of achieving successful tobacco abstinence among treatment-seeking tobacco smokers. The present study examined whether current cannabis use moderated tobacco cessation outcomes after 12 weeks of pharmacological treatment (varenicline vs. nicotine patch vs. placebo) with adjunctive behavioral counseling. Treatment-seeking tobacco smokers (N = 1,246) were enrolled in an intent-to-treat study, of which 220 were current cannabis users. Individuals were randomly assigned to 12 weeks of placebo (placebo pill plus placebo patch), nicotine patch (active patch plus placebo pill), or varenicline (active pill plus placebo patch), plus behavioral counseling. The primary endpoint was biochemically verified 7-day point prevalence abstinence at the end of treatment. Controlling for rate of nicotine metabolism, treatment arm, age, sex, alcohol, and level of nicotine dependence, cannabis users were as successful at achieving biochemically verified 7-day point prevalence abstinence compared to tobacco-only smokers. Findings suggest that cannabis use does not hinder the ability to quit tobacco smoking. Future tobacco cessation studies should employ prospective, longitudinal designs investigating cannabis co-use over time and at different severity levels.

Full Text Available Background: The National Acupuncture Detoxification Association (NADA protocol, a simple standardized auricular treatment has the potential to provide vast public health relief on issues currently challenging our world. This includes but is not limited to addiction, such as the opioid epidemic, but also encompasses mental health, trauma, PTSD, chronic stress, and the symptoms associated with these conditions. Simple accessible tools that improve outcomes can make profound differences. We assert that the NADA protocol can have greatest impact when broadly applied by behavioral health professionals, Auricular Detoxification Specialists (ADSes. Methods: The concept of ADS is described and how current laws vary from state to state. Using available national data, a survey of practitioners in three selected states with vastly different laws regarding ADSes, and interviews of publicly funded programs which are successfully incorporating the NADA protocol, we consider possible effects of ADS-friendly conditions. Results: Data presented supports the idea that conditions conducive to ADS practice lead to greater implementation. Program interviews reflect settings in which adding ADSes can in turn lead to improved outcomes. Discussion: The primary purpose of non-acupuncturist ADSes is to expand the access of this simple but effective treatment to all who are suffering from addictions, stress, or trauma and to allow programs to incorporate acupuncture in the form of the NADA protocol at minimal cost, when and where it is needed. States that have changed laws to allow ADS practice for this standardized ear acupuncture protocol have seen increased access to this treatment, benefiting both patients and the programs.

Full Text Available Background: In the recent decades increasing number of women have been seeking deaddiction services. Despite that the report data is very limited from India. Objectives: The present research aimed to study the demographic and clinical profile of women seeking deaddiction treatment at a tertiary care center in North India. Materials and Methods: Retrospective structured chart review of 100 women substance abusers seeking treatment at a deaddiction center between September 1978 and December 2011. Results: A typical case was of 36.3 years age, married (65%, urban (61%, nuclear family (59% based housewife (56%, with good to fair social support (69%. The commonest substance of abuse was tobacco (60%, followed by opioids (27%, alcohol (15%, and benzodiazepines (13%. The common reasons for initiation of substance use were to alleviate frustration or stress (49% and curiosity (37%. Family history of drug dependence (43%, comorbidity (25%, and impairments in health (74%, family (57%, and social domains (56% were common. Only a third of the sample paid one or more follow visit, and of those 58% were abstinent at the last follow-up. Significant predictors identified were being non-Hindu and higher educational years for abstinent status at follow-up. Conclusion: The common substances of abuse were tobacco, opioids, and alcohol and benzodiazepines; and family history of drug abuse and comorbidity were common. The follow-up and outcome were generally poor. This profile gives us some clues to address a hidden health problem of the community.

As epidemiological data concerning gender-related help-seeking behaviour indicate, consultation rate and help-seeking by men is consistently lower, especially in the case of emotional problems and depressive symptoms. There is empirical evidence that the poor treatment rate of men cannot be explained by a better health but must be attributed to a discrepancy of need and help-seeking behaviour. Social change and epidemiological trends in depression point to the male gender-role being an important factor of increasing rates among young men as well as an important determinant of help-seeking behaviour. It is argued that social norms of traditional masculinity make help-seeking more difficult because of the inhibition of expressiveness affecting symptom perception and symptomatology of depression. Besides these predisposing factors of male help-seeking other medical and social factors are mentioned producing further barriers to help-seeking. Further research is needed to investigate the question whether changing masculinity implies gender-role conflict or positive health effects.

Full Text Available Abstract Background Post-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access. Methods We conducted 4 semi-structured focus groups comprising altogether 28 Japanese gynecological cancer survivors to collect a variety of participants’ post-treatment care-seeking behaviors through active interaction with participants. Factors influencing access to treatment for adverse effects were analyzed qualitatively. Results Survivors sought care through specialty clinic visits when regular post-treatment gynecological follow-ups were inadequate or when symptoms seemed to be non-treatment related. Information provided by hospital staff during initial treatment influenced patients’ understanding and response to adverse effects. Lack of knowledge and inaccurate symptom interpretation delayed help-seeking, exacerbating symptoms. Gynecologists’ attitudes during follow-ups frequently led survivors to cope with symptoms on their own. Information from mass media, Internet, and support groups helped patients understand symptoms and facilitated care seeking. Conclusions Post-treatment adverse effects are often untreated during follow-up visits. Awareness of possible post-treatment adverse effects is important for gynecological cancer survivors in order to obtain appropriate care if the need arises. Consultation during the follow-up visit is essential for continuity in care.

Aldehyde reductase (AKR1A), a member of the aldo-keto reductase superfamily, suppresses diabetic complications via a reduction in metabolic intermediates; it also plays a role in ascorbic acid biosynthesis in mice. Because primates cannot synthesize ascorbic acid, a principle role of AKR1A appears to be the reductive detoxification of aldehydes. In this study, we isolated and immortalized mouse embryonic fibroblasts (MEFs) from wild-type (WT) and human Akr1a-transgenic (Tg) mice and used them to investigate the potential roles of AKR1A under culture conditions. Tg MEFs showed higher methylglyoxal- and acrolein-reducing activities than WT MEFs and also were more resistant to cytotoxicity. Enzymatic analyses of purified rat AKR1A showed that the efficiency of the acrolein reduction was about 20% that of glyceraldehyde. Ascorbic acid levels were quite low in the MEFs, and while the administration of ascorbic acid to the cells increased the intracellular levels of ascorbic acid, it had no affect on the resistance to acrolein. Endoplasmic reticulum stress and protein carbonylation induced by acrolein treatment were less evident in Tg MEFs than in WT MEFs. These data collectively indicate that one of the principle roles of AKR1A in primates is the reductive detoxification of aldehydes, notably acrolein, and protection from its detrimental effects.

This survey investigated the prevalence of ethnomedical syndromes and examined treatments and treatment-seeking in Mayan Guatemalans living in United Nations High Commissioner for Refugee (UNHCR) camps in Chiapas, Mexico. Methods included a rapid ethnographic assessment to refine survey methods and inform the cross-sectional survey, which also examined mental health outcomes; 183 households were approached for interview, representing an estimated 1,546 residents in five refugee camps and 93% of all households. One adult per household (N = 170) was interviewed regarding his or her health; an additional 9 adults in three surveyed households participated and were included in this analysis; of the 179 participants, 95 primary child-care providers also answered a children's health questionnaire for their children. Results indicated that ethnomedical syndromes were common in this sample, with 59% of adults and 48.4% of children having experienced susto (fright condition) and 34.1% of adults reporting ataques de nervios (nervous attacks); both conditions were significantly associated with symptoms consistent with posttraumatic stress disorder, anxiety and depression and are mental health conditions recognized by the American Psychiatric Association. Combining healthcare provider and indigenous treatments such as physician prescribed medication (65%), medicinal plants (65.7%), and limpias (spiritual cleansings) (40.6%) was reported. Most participants (86%) sought routine medical treatment from UNHCR trained health promoters in their camp. Assessing ethnomedical health is important for informing mental health programs among this population.

The present investigation was aimed to study the effect of detoxification on the nutrients and antinutrients of wild apricot kernel followed by its hypocholesterolemic effect in male Wistar albino rats. The results revealed a non-significant (p > 0.05) effect of detoxification on the proximate composition except total carbohydrates and protein content. However, detoxification led to a significant (p acid (76.82%), β-carotene (25.90%), dietary fiber constituents (10.51-28.92%), minerals (4.76-31.08%) and antinutritional factors (23.92-77.05%) (phenolics, tannins, trypsin inhibitor activity, saponins, phytic acid, alkaloids, flavonoids, oxalates) along with the complete removal (100%) of bitter and potentially toxic hydrocyanic acid (HCN). The quality parameters of kernel oil indicated no adverse effects of detoxification on free fatty acids, lipase activity, acid value and peroxide value, which remained well below the maximum permissible limit. Blood lipid profile demonstrated that the detoxified apricot kernel group exhibited significantly (p < 0.05) increased levels of HDL-cholesterol (48.79%) and triglycerides (15.09%), and decreased levels of total blood cholesterol (6.99%), LDL-C (22.95%) and VLDL-C (7.90%) compared to that of the raw (untreated) kernel group. Overall, it can be concluded that wild apricot kernel flour could be detoxified efficiently by employing a simple, safe, domestic and cost-effective method, which further has the potential for formulating protein supplements and value-added food products.

Phytoremediation has been proven to be an environmentally sound alternative for the recovery of contaminated soils, and the economic profit that comes along with the process might stimulate its field use. This study investigated cadmium (Cd) transfer and detoxification mechanisms in a soil-mulberry-silkworm system to estimate the suitability of the mulberry and silkworm as an alternative method for the remediation of Cd-polluted soil; it also explored the underlying mechanisms regulating the trophic transfer of Cd. The results show that both the mulberry and silkworm have high Cd tolerance. The transfer factor suggests that the mulberry has high potential for Cd extraction from polluted soil. The subcellular distribution and chemical forms of Cd in mulberry leaves show that cell wall deposition and vacuolar compartmentalization play important role in Cd tolerance. In the presence of increasing Cd concentrations in silkworm food, detoxification mechanisms (excretion and homeostasis) were activated so that excess Cd was excreted in fecal balls, and metallothionein levels in the mid-gut, the posterior of the silk gland, and the fat body of silkworms were enhanced. And, the Cd concentrations in silk are at a low level, ranging from 0.02 to 0.21 mg kg(-1). Therefore, these mechanisms of detoxification can regulate Cd trophic transfer, and mulberry planting and silkworm breeding has high phytoremediation potential for Cd-contaminated soil.

2013-12-01

Full Text Available Data on genome damage, lipid peroxidation, and levels of glutathione peroxidase (GPX in newborns after transplacental exposure to xenobiotics are rare and insufficient for risk assessment. The aim of the current study was to analyze, in an animal model, transplacental genotoxicity, lipid peroxidation, and detoxification disturbances caused by the following drugs commonly prescribed to pregnant women: paracetamol, fluconazole, 5-nitrofurantoin, and sodium valproate. Genome damage in dams and their newborn pups transplacentally exposed to these drugs was investigated using the in vivo micronucleus (MN assay. The drugs were administered to dams intraperitoneally in three consecutive daily doses between days 12 and 14 of pregnancy. The results were correlated, with detoxification capacity of the newborn pups measured by the levels of GPX in blood and lipid peroxidation in liver measured by malondialdehyde (HPLC-MDA levels. Sodium valproate and 5-nitrofurantoin significantly increased MN frequency in pregnant dams. A significant increase in the MN frequency of newborn pups was detected for all drugs tested. This paper also provides reference levels of MDA in newborn pups, according to which all drugs tested significantly lowered MDA levels of newborn pups, while blood GPX activity dropped significantly only after exposure to paracetamol. The GPX reduction reflected systemic oxidative stress, which is known to occur with paracetamol treatment. The reduction of MDA in the liver is suggested to be an unspecific metabolic reaction to the drugs that express cytotoxic, in particular hepatotoxic, effects associated with oxidative stress and lipid peroxidation.

Treatment of textile wastewater containing anthraquinone dye is quite a huge challenge due to its complex aromatic structure and toxicity. Present study deals with the degradation and detoxification of anthraquinone dye reactive blue 4 using aerobic bacterial granules. Bacterial granules effectively decolorized reactive blue 4 at wide range of pH (4.0-11.0) and temperature (20-55 °C) as well as decolorized and tolerated high concentration of reactive blue 4 dye upto 1000 mg l -1 with V max 6.16 ± 0.82 mg l -1 h -1 and K m 227 ± 41 mg l -1 . Metagenomics study evaluates important role of Clostridia, Actinobacteria, and Proteobacterial members in biotransformation and tolerance of high concentrations of reactive blue 4 dye. Up-regulation of xenobiotic degradation and environmental information processing pathways during dye exposure signifies their noteworthy role in dye degradation. Biotransformation of dye was confirmed by significant decrease in the values of total suspended solids, biological and chemical oxygen demand. The metabolites formed after biotransformation was characterized by FT-IR and GC-MS analysis. The reactive blue 4 dye was found to be phytotoxic, cytotoxic and genotoxic whereas its biotransformed product were non-toxic. This study comprehensively illustrates that, bacterial aerobic granules can be used for eco-friendly remediation and detoxification of wastewater containing high organic load of anthraquinone dye.

Freitas-Murrell, Brittany; Swift, Joshua K

2015-01-01

This study sought to examine the role of current/previous treatment experience, stigma (social and self), and cultural identification (Caucasian and Alaska Native [AN]) in predicting attitudes toward psychological help seeking for ANs. Results indicated that these variables together explained roughly 56% of variance in attitudes. In particular, while self-stigma and identification with the Caucasian culture predicted a unique amount of variance in help-seeking attitudes, treatment use and identification with AN culture did not. The results of this study indicate that efforts to address the experience of self-stigma may prove most useful to improving help-seeking attitudes in ANs.

Azo dyes are known to be a very important and widely used class of toxic and carcinogenic compounds. Although lot of research has been carried out for their removal from industrial effluents, very little attention is given to changes in their toxicity and mutagenicity during the treatment processes. Present investigation describes isolation of a Bacillus velezensis culture capable of degrading azo dye Direct Red 28 (DR28). Azoreductase enzyme was isolated from it, and its molecular weight was found to be 60 kDa. The enzyme required NADH as cofactor and was oxygen-insensitive. Toxicity and mutagenicity of the dye during biodegradation was monitored by using a battery of carefully selected in vitro tests. The culture was found to degrade DR28 to benzidine and 4-aminobiphenyl, both of which are potent mutagens. However, on longer incubation, both the compounds were degraded further, resulting in reduction in toxicity and mutagenicity of the dye. Thus, the culture seems to be a suitable candidate for further study for both decolourization and detoxification of azo dyes, resulting in their safe disposal.

2017-03-08

ZmGST34 is a maize Tau class GST gene and was found to be differently expressed between two maize cultivars differing in tolerance to herbicide metolachlor. To explore the possible role of ZmGST34 in maize development, the expression pattern and substrate specificity of ZmGST34 were characterized by quantitative RT-PCR and heterologous expression system, respectively. The results indicated that the expression level of ZmGST34 was increased ∼2-5-fold per day during the second-leaf stage of maize seedling. Chloroacetanilide herbicides or phytohormone treatments had no influence on the expression level of ZmGST34, suggesting that ZmGST34 is a constitutively expressed gene in maize seedling. Heterologous expression in Escherichia coli and in Arabidopsis thaliana proved that ZmGST34 can metabolize most chloroacetanilide herbicides and increase tolerance to these herbicides in transgenic Arabidopsis thaliana. The constitutive expression pattern and broad substrate activity of ZmGST34 suggested that this gene may play an important role in maize development in addition to the detoxification of pesticides.

Relapse to old, unhealthy eating habits is a major problem in human dietary treatments. The mechanisms underlying this relapse are unknown. Surprisingly, until recently this clinical problem has not been systematically studied in animal models. Here, we review results from recent studies in which a reinstatement model (commonly used to study relapse to abused drugs) was employed to characterize the effect of pharmacological agents on relapse to food seeking induced by either food priming (non-contingent exposure to small amounts of food), cues previously associated with food, or injections of the pharmacological stressor yohimbine. We also address methodological issues related to the use of the reinstatement model to study relapse to food seeking, similarities and differences in mechanisms underlying reinstatement of food seeking versus drug seeking, and the degree to which the reinstatement procedure provides a suitable model for studying relapse in humans. We conclude by discussing implications for medication development and future research. We offer three tentative conclusions: (1)The neuronal mechanisms of food-priming- and cue-induced reinstatement are likely different from those of reinstatement induced by the pharmacological stressor yohimbine. (2)The neuronal mechanisms of reinstatement of food seeking are possibly different from those of ongoing food-reinforced operant responding. (3)The neuronal mechanisms underlying reinstatement of food seeking overlap to some degree with those of reinstatement of drug seeking.

Oxidation and detoxification of trivalent arsenic species

Aposhian, H. Vasken; Zakharyan, Robert A.; Avram, Mihaela D.; Kopplin, Michael J.; Wollenberg, Michael L.

Arsenic compounds with a +3 oxidation state are more toxic than analogous compounds with a +5 oxidation state, for example, arsenite versus arsenate, monomethylarsonous acid (MMA III ) versus monomethylarsonic acid (MMA V ), and dimethylarsinous acid (DMA III ) versus dimethylarsinic acid (DMA V ). It is no longer believed that the methylation of arsenite is the beginning of a methylation-mediated detoxication pathway. The oxidation of these +3 compounds to their less toxic +5 analogs by hydrogen peroxide needs investigation and consideration as a potential mechanism for detoxification. Xanthine oxidase uses oxygen to oxidize hypoxanthine to xanthine to uric acid. Hydrogen peroxide and reactive oxygen are also products. The oxidation of +3 arsenicals by the hydrogen peroxide produced in the xanthine oxidase reaction was blocked by catalase or allopurinol but not by scavengers of the hydroxy radical, e.g., mannitol or potassium iodide. Melatonin, the singlet oxygen radical scavenger, did not inhibit the oxidation. The production of H 2 O 2 by xanthine oxidase may be an important route for decreasing the toxicity of trivalent arsenic species by oxidizing them to their less toxic pentavalent analogs. In addition, there are many other reactions that produce hydrogen peroxide in the cell. Although chemists have used hydrogen peroxide for the oxidation of arsenite to arsenate to purify water, we are not aware of any published account of its potential importance in the detoxification of trivalent arsenicals in biological systems. At present, this oxidation of the +3 oxidation state arsenicals is based on evidence from in vitro experiments. In vivo experiments are needed to substantiate the role and importance of H 2 O 2 in arsenic detoxication in mammals

Full Text Available This cross-sectional descriptive survey investigated determinants of malaria prevention and treatment seeking behaviours of pregnant undergraduates resident in university hostels, South-East Nigeria. Purposive sampling was used to enrol 121 accessible and consenting undergraduates with self-revealed and noticeable pregnancy residing in twenty-three female hostels of four university campuses in Enugu State, Nigeria. Structured interview guide developed based on reviewed literature and WHO-recommended malaria prevention and treatment measures was used to collect students’ self-report data on malaria preventive health behaviours, sick role behaviours, and clinic use using mixed methods. The WHO-recommended malaria prevention measures were sparingly used. Some believed that pregnancy does not play any role in a woman’s reaction to malaria infection. Only 41 (50.6% visited a hospital for screening and treatment. Thirty-four (28.1% used antimalaria medicine bought from chemist shop or over-the-counter medicines, while 33 (27.3% used untreated net. The students were more likely to complete their antimalaria medicine when they were sick with malaria infection than for prevention (p=0.0186. Knowledge, academic schedule, cultural influence on perception and decision-making, and accessibility of health facility were key determinants of the women’s preventive and treatment seeking behaviours. Health education on malaria prevention and dangers of drug abuse should form part of orientation lectures for all freshmen. University health centres should be upgraded to provide basic antenatal care services.

Systemic treatment with D-fenfluramine, but not sibutramine, blocks cue-induced reinstatement of food-seeking behavior in the rat.

Pratt, Wayne E; Ford, Ryan T

Individuals struggling with obesity often have difficulty maintaining dietary regimens. One source of dietary relapse is the reinstatement of previous feeding behaviors following the presentation of cues indicating the availability of palatable but highly caloric food reward. The drugs fenfluramine and sibutramine have previously been prescribed because they enhance satiety mechanisms and decrease meal size. However, it is unclear whether these anorectic agents are also effective in blocking the cue-induced reinstatement of food-seeking behaviors. In these three experiments, we compared the effects of systemic treatment of d-fenfluramine (3mg/kg; N=10) and sibutramine (3mg/kg; N=11) with that of the D1 antagonist SCH 23390 (6μg/kg; N=11) at a dose that has previously been shown to attenuate cue-induced reinstatement. d-Fenfluramine treatment blocked the cue's ability to reinstate lever pressing as compared to the saline injection day. In contrast, sibutramine had no effect on cue-induced reinstatement; all animals reinstated their lever pressing during the first reinstatement test, and this was unaffected by sibutramine treatment. SCH 23390 treatment did not significantly reduce cue-induced reinstatement in this set of experiments. The results suggest that the motivational effects of d-fenfluramine is not limited to the promotion of satiety once a meal has been initiated, and demonstrate that some anorectic treatments may inhibit the effectiveness of conditioned cues to elicit relapse of food-seeking behavior.

Mental health stigma has been associated with delays in seeking treatment. To describe perceived stigma experienced by patients and carers in Sri Lanka and to determine the effects of stigma on help-seeking delay. Survey of outpatients and family carers (n = 118 dyads) attending two psychiatric hospitals in Sri Lanka, using the Disclosure and Discrimination subscales of the Stigma Scale. Stigma was positively related to help-seeking delay for carers but not patients. Public stigma experienced by carers accounted for 23% of the variance in help-seeking delay. Reducing stigma may reduce help-seeking delays during the course of treatment. © 2016 John Wiley & Sons Australia, Ltd.

PEI detoxification of pretreated spruce for high solids ethanol fermentation

Cannella, David; Sveding, Per Viktor; Jørgensen, Henning

2014-01-01

Highlights: • High solids (30% dry matter) pretreatment, enzymatic hydrolysis and fermentation. • Horizontal rotary reactor for hydrolysis and fermentation. • In situ hydrolysates detoxification using inhibitors adsorbing PEI polymer. • 50% of inhibitors recovered as by-product, recyclability of PEI polymer up to 5 times. • 76% of maximum theoretical ethanol was fermented at final concentration of 51 g/kg. - Abstract: Performing the bioethanol production process at high solids loading is a requirement for economic feasibility at industrial scale. So far this has successfully been achieved using wheat straw and other agricultural residues at 30% of water insoluble solids (WIS), but for softwood species (i.e. spruce) this has been difficult to reach. The main reason behind this difference is the higher recalcitrance of woody substrates which require harsher pretreatment conditions, thus generating higher amounts of inhibitory compounds, ultimately lowering fermentation performances. In this work we studied ethanol production from spruce performing the whole process, from pretreatment to hydrolysis and fermentation, at 30% dry matter (equivalent to ∼20% WIS). Hydrolysis and fermentation was performed in a horizontal free fall mixing reactor enabling efficient mixing at high solids loadings. In batch simultaneous saccharification and fermentation (SSF), up to 76% cellulose to ethanol conversion was achieved resulting in a concentration of 51 g/kg of ethanol. Key to obtaining this high ethanol yield at these conditions was the use of a detoxification technology based on applying a soluble polyelectrolyte polymer (polyethylenimine, PEI) to absorb inhibitory compounds in the material. On average 50% removal and recovery of the main inhibitors (HMF, furfural, acetic acid and formic acid) was achieved dosing 1.5% w/w of soluble PEI. The use of PEI was compatible with operating the process at high solids loadings and enabled fermentation of hydrolysates, which

The toxic fermentation inhibitors in lignocellulosic hydrolysates raise serious problems for the microbial production of fuels and chemicals. Furfural is considered to be one of the most toxic compounds among these inhibitors. Here, we describe the detoxification of furfural in Corynebacterium glutamicum ATCC13032 under both aerobic and anaerobic conditions. Under aerobic culture conditions, furfuryl alcohol and 2-furoic acid were produced as detoxification products of furfural. The ratio of the products varied depending on the initial furfural concentration. Neither furfuryl alcohol nor 2-furoic acid showed any toxic effect on cell growth, and both compounds were determined to be the end products of furfural degradation. Interestingly, unlike under aerobic conditions, most of the furfural was converted to furfuryl alcohol under anaerobic conditions, without affecting the glucose consumption rate. Both the NADH/NAD(+) and NADPH/NADP(+) ratio decreased in the accordance with furfural concentration under both aerobic and anaerobic conditions. These results indicate the presence of a single or multiple endogenous enzymes with broad and high affinity for furfural and co-factors in C. glutamicum ATCC13032.

Strategies and Methodologies for Developing Microbial Detoxification Systems to Mitigate Mycotoxins

Directory of Open Access Journals (Sweden)

Yan Zhu

2017-04-01

Full Text Available Mycotoxins, the secondary metabolites of mycotoxigenic fungi, have been found in almost all agricultural commodities worldwide, causing enormous economic losses in livestock production and severe human health problems. Compared to traditional physical adsorption and chemical reactions, interest in biological detoxification methods that are environmentally sound, safe and highly efficient has seen a significant increase in recent years. However, researchers in this field have been facing tremendous unexpected challenges and are eager to find solutions. This review summarizes and assesses the research strategies and methodologies in each phase of the development of microbiological solutions for mycotoxin mitigation. These include screening of functional microbial consortia from natural samples, isolation and identification of single colonies with biotransformation activity, investigation of the physiological characteristics of isolated strains, identification and assessment of the toxicities of biotransformation products, purification of functional enzymes and the application of mycotoxin decontamination to feed/food production. A full understanding and appropriate application of this tool box should be helpful towards the development of novel microbiological solutions on mycotoxin detoxification.

The Solar Detoxification Field Experiment was designed to investigate the photocatalytic decomposition of organic contaminants in groundwater at a Superfund site at Lawrence Livermore National Laboratory (LLNL). The process uses ultraviolet (UV) energy, available in sunlight, in conjunction with the photocatalyst, titanium dioxide, to decompose organic chemicals into nontoxic compounds. The field experiment was developed by three federal laboratories: the National Renewable Energy Laboratory (NREL), Sandia National Laboratory (SNLA), and LLNL. The US Department of Energy funded the experiment. The objectives of the pilot-scale study included the advancement of the solar technology into a nonlaboratory waste-remediation environment the compilation of test data to help guide laboratory research and future demonstrations and the development of safe operational procedures. Results of the pilot study are discussed, emphasizing the effect of several process variables on the system performance. These variables include alkalinity, catalyst loading, flow velocity through the reactor, and incident solar UV radiation. The performance of the solar detoxification process are discussed as it relates to concentrating and nonconcentrating collectors

Pharmacies in Bangladesh serve as an important source of health service. A survey in Dhaka reported that 48% of respondents with symptoms of acute respiratory illness (ARI) identified local pharmacies as their first point of care. This study explores the factors driving urban customers to seek health care from pharmacies for ARI, their treatment adherence, and outcome. A cross-sectional study was conducted among 100 selected pharmacies within Dhaka from June to December 2012. Study participants were patients or patients' relatives aged >18 years seeking care for ARI from pharmacies without prescription. Structured interviews were conducted with customers after they sought health service from drug sellers and again over phone 5 days postinterview to discuss treatment adherence and outcome. We interviewed 302 customers patronizing 76 pharmacies; 186 (62%) sought care for themselves and 116 (38%) sought care for a sick relative. Most customers (215; 71%) were males. The majority (90%) of customers sought care from the study pharmacy as their first point of care, while 18 (6%) had previously sought care from another pharmacy and 11 (4%) from a physician for their illness episodes. The most frequently reported reasons for seeking care from pharmacies were ease of access to pharmacies (86%), lower cost (46%), availability of medicine (33%), knowing the drug seller (20%), and convenient hours of operation (19%). The most commonly recommended drugs were acetaminophen dispensed in 76% (228) of visits, antihistamine in 69% (208), and antibiotics in 42% (126). On follow-up, most (86%) of the customers had recovered and 12% had sought further treatment. People with ARI preferred to seek care at pharmacies rather than clinics because these pharmacies were more accessible and provided prompt treatment and medicine with no service charge. We recommend raising awareness among drug sellers on proper dispensing practices and enforcement of laws and regulations for drug sales.

Full Text Available Abstract: Tuberculosis (TB remains a significant public health challenge worldwide, and particularly in Peru with one of the highest incidence rates in Latin America. TB patient behavior has a direct influence on whether a patient will receive timely diagnosis and successful treatment of their illness. Objectives: The objective was to understand the complex factors that can impact TB patient health seeking behavior. Methods: In-depth interviews were conducted with adult and parents of pediatric patients receiving TB treatment (n=43, within that group a sub-group was also co-infected with HIV (n=11. Results: Almost all of the study participants recognized delays in seeking either their child’s or their own diagnosis of their TB symptoms. The principal reasons for treatment-seeking delays were lack of knowledge and confusion of tuberculosis symptoms, fear and embarrassment of receiving a TB diagnosis, and a patient tendency to self-medicate prior to seeking formal medical attention.Conclusions: Health promotion activities that target patient delays have the potential to improve individual patient outcomes and mitigate the spread of TB at a community level.

Full Text Available Arsenic (As, naturally occurring metalloid and a potential hazardous material, is found in low concentrations in the environment and emerges from natural sources and anthropogenic activities. The presence of As in ground water, which is used for irrigation, is a matter of great concern since it affects crop productivity and contaminates food chain. In plants, As alters various metabolic pathways in cells including the interaction of substrates/enzymes with the sulfhydryl groups of proteins and the replacement of phosphate in ATP for energy. In addition, As stimulates the generation of free radicals and reactive oxygen species (ROS, resulting in oxidative stress. Glutathione S-transferases (GSTs quench reactive molecules with the addition of glutathione (GSH and protect the cell from oxidative damage. GSTs are a multigene family of isozymes, known to catalyze the conjugation of GSH to miscellany of electrophilic and hydrophobic substrates. GSTs have been reported to be associated with plant developmental processes and are responsive to multitude of stressors. In past, several studies suggested involvement of plant GST gene family in As response due to the requirement of sulfur and GSH in the detoxification of this toxic metalloid. This review provides updated information about the role of GSTs in abiotic and biotic stresses with an emphasis on As uptake, metabolism, and detoxification in plants. Further, the genetic manipulations that helped in enhancing the understanding of the function of GSTs in abiotic stress response and heavy metal detoxification has been reviewed.

Depression is an illness increasingly constructed as a gendered mood disorder and consequently diagnosed in women more than men. The diagnostic criteria used for its assessment often perpetrate and reproduce gender stereotypes. The stigma associated with mental illness and the gendered elements of depression suggest there are likely numerous discourses that position, explain, and justify help-seeking practices. This qualitative study explored men's discourses of seeking help for depression. The methodological approach was informed by a social constructionist perspective of language, discourse and gender that drew on methods from discourse analysis. We conducted individual in-depth, semi-structured interviews with 38 men with depression, either formally diagnosed or self reported. The analysis revealed five discursive frames that influenced the men's talk about help-seeking and depression: manly self-reliance; treatment-seeking as responsible independent action; guarded vulnerability; desperation; and genuine connection. The findings are discussed within a broader context of social discourses of gender, the limitations of current help-seeking literature and the evidence for how men seek help in ways that extend traditional notions of medical treatment. © 2011 The Authors.

Inhibition of the respiration of activated sludge has been tested as a convenient method to estimate toxicity of aqueous solutions containing copper and cyanide, such as metal finishing effluents; according to this method, an EC 50 of 0.5 mg/l was determined for CN - and 3.0 mg/l for copper. Solar detoxification of cyanide-containing solutions was studied using TiO 2 , but this process was unfavourable because of the inhibitory role that plays the copper ions present in real effluents on the oxidation of cyanide. On the other hand, the oxidative effect of hydrogen peroxide was greatly enhanced by Cu 2+ and solar irradiation, as complete elimination of free and complexed cyanide could be accomplished, together with precipitation of copper, in experiments carried out at pilot plant scale with real metal finishing effluents. Under these conditions, total detoxification was achieved according to respirometric measurements although some remaining toxicity was determined by more sensitive Vibrio fischeri luminescent assay

Kinetics of Natural Detoxification of Hydrogen Cyanide Contained In Retted Cassava Roots

Full Text Available This work presents the kinetics of natural detoxification of hydrogen cyanide contained in retted cassava roots. Retting is traditional fermentation of cassava, performed to soften the roots. During retting, cyanide diffuses into water used for the retting. The fresh cassava roots (bitter and sweet varieties used for this experiment were separately retted at ambient 0 temperature of 30 C. The cyanide content and pH were monitored daily. From the analysis of the experimental results, a first order consecutive rate equation is an adequate tool for explaining the mechanism of HCN reduction (or decay in retted cassava roots. The detoxification constants for the bound cyanide in the bitter and sweet cassava roots were 0.378/day and 0.438/day respectively, while that of the free hydrogen cyanide were 0.63/day and 0.74/day for the bitter and sweet varieties respectively. Cassava tubers from different species cannot be fermented with the same retting condition unless they have same or close functional properties.

Full Text Available Abstract Background This study used qualitative methods to investigate the relationship between geographic access and gendered intra-household hierarchies and how these influence treatment-seeking decision-making for childhood fever within the Chikwawa district of Malawi. Previous cross-sectional survey findings in the district indicated that distance from facility and associated costs are important determinants of health facility attendance in the district. This paper uses qualitative data to add depth of understanding to these findings by exploring the relationship between distance from services, anticipated costs and cultural norms of intra-household decision-making, and to identify potential intervention opportunities to reduce challenges experienced by those in remote locations. Qualitative data collection included 12 focus group discussions and 22 critical incident interviews conducted in the local language, with primary caregivers of children who had recently experienced a febrile episode. Results Low geographic accessibility to facilities inhibited care-seeking, sometimes by extending the ‘assessment period’ for a child’s illness episode, and led to delays in seeking formal treatment, particularly when the illness occurred at night. Although carers attempted to avoid incurring costs, cash was often needed for transport and food. Whilst in all communities fathers were normatively responsible for treatment costs, mothers generally had greater access to and control over resources and autonomy in decision-making in the matrilineal and matrilocal communities in the central part of the district, which were also closer to formal facilities. Conclusions This study illustrates the complex interplay between geographic access and gender dynamics in shaping decisions on whether and when formal treatment is sought for febrile children in Chikwawa District. Geographic marginality and cultural norms intersect in remote areas both to increase the

The objective of this study was to identify factors that determine medical treatment seeking behaviour following potential rabies exposure after being bitten by a suspected dog and the likelihood of compliance to receive sufficient doses of post-exposure prophylaxis after the visit to a health centre visit. A detailed survey based on case investigation was conducted on suspected rabid dog bite cases in three areas of Ethiopia. Two multivariable logistic regression models were created with a set of putative variables to explain treatment seeking and compliance outcomes. Based on the registered bite cases at each health centre and the set of unregistered bite cases derived by contact tracing, 655 bite victim cases were identified to have occurred between September 2013 and August 2014. Of these evaluated bite incidences, 465 cases were considered to have been caused by a potentially rabid dog. About 77% of these suspected rabid dog bite victims visited a health centre, while 57% received sufficient doses of PEP. The overall likelihood of seeking medical services following rabies exposure was higher for people bitten by dogs of unknown ownership, where the bite was severe, being bitten on the leg, spend of more than 100 USD per month and where the victim lived close to the nearest health centre, while the likelihood of receiving sufficient doses of PEP was sensitive to monthly spending and distance to health centre. However, the evaluated factors did only explain a part of the variation among the three districts. The district in which victims lived appeared to have a relevant influence on the likelihood of seeking medical treatment but did not improve the prediction on the likelihood of treatment compliance. Given the insights obtained from this study, improvements in the rural districts with regard to accessibility of post-exposure prophylaxis delivering health centres in shorter distance could improve health seeking behaviour. In addition, in rural districts

Atrazine (ATR) and isoproturon (IPU) as herbicides have become serious environmental contaminants due to their overuse in crop production. Although ATR and IPU in soils are easily absorbed by many crops, the mechanisms for their degradation or detoxification in plants are poorly understood. This study identified a group of novel genes encoding laccases (EC 1.10.3.2) that are possibly involved in catabolism or detoxification of ATR and IPU residues in rice. Transcriptome profiling shows at least 22 differentially expressed laccase genes in ATR/IPU-exposed rice. Some of the laccase genes were validated by RT-PCR analysis. The biochemical properties of the laccases were analyzed, and their activities in rice were induced under ATR/IPU exposure. To investigate the roles of laccases in degrading or detoxifying ATR/IPU in rice, transgenic yeast cells (Pichia pastoris X-33) expressing two rice laccase genes (LOC_Os01g63180 and LOC_Os12g15680) were generated. Both transformants were found to accumulate less ATR/IPU compared to the control. The ATR/IPU-degraded products in the transformed yeast cells using UPLC-TOF-MS/MS were further characterized. Two metabolites, hydroxy-dehydrogenated atrazine (HDHA) and 2-OH-isopropyl-IPU, catalyzed by laccases were detected in the eukaryotic cells. These results indicate that the laccase-coding genes identified here could confer degradation or detoxification of the herbicides and suggest that the laccases could be one of the important enzymatic pathways responsible for ATR/IPU degradation/detoxification in rice.

Platinum drug delivery against the detoxification of cytoplasmic thiols is urgently required for achieving efficacy in breast cancer treatment that is over expressed by glutathione (GSH, thiol-oligopeptide). GSH-resistant polymer-cisplatin core-shell nanoparticles were custom designed based on biodegradable carboxylic functional polycaprolactone (PCL)-block-poly(ethylene glycol) diblock copolymers. The core of the nanoparticle was fixed as 100 carboxylic units and the shell part was varied using various molecular weight poly(ethylene glycol) monomethyl ethers (MW of PEGs = 100-5000 g mol-1) as initiator in the ring-opening polymerization. The complexation of cisplatin aquo species with the diblocks produced core-shell nanoparticles of 75 nm core with precise size control the particles up to 190 nm. The core-shell nanoparticles were found to be stable in saline solution and PBS and they exhibited enhanced stability with increase in the PEG shell thickness at the periphery. The hydrophobic PCL layer on the periphery of the cisplatin core behaved as a protecting layer against the cytoplasmic thiol residues (GSH and cysteine) and exhibited embryonic fibroblast cells (Wt-MEFs), and breast cancer (MCF-7) and cervical cancer (HeLa) cell lines. Free cisplatin and polymer drug core-shell nanoparticles showed similar cytotoxicity effects in the HeLa cells. In MCF-7 cells, the free cisplatin drug exhibited 50% cell death whereas complete cell death (100%) was accomplished by the polymer-cisplatin core-shell nanoparticles. Confocal microscopic images confirmed that the core-shell nanoparticles were taken up by the MCF-7 and HeLa cells and they were accumulated both at the cytoplasm as well at peri-nuclear environments. The present investigation lays a new foundation for the polymer-based core-shell nanoparticles approach for overcoming detoxification in platinum drugs for the treatment of GSH over-expressed breast cancer cells.Platinum drug delivery against the detoxification

Full Text Available Background. Nonmedical prescription opioid use (NMPOU is a growing problem and tramadol has been suggested as an emerging problem in young treatment-seeking individuals. The aim of the present study was to investigate, through hair analysis, NMPOU in this group and, specifically, tramadol use. Methods. In a study including 73 treatment-seeking adolescents and young adults at an outpatient facility for young substance users, hair specimens could be obtained from 59 subjects. Data were extracted on sociodemographic background variables and psychiatric diagnoses through MINI interviews. Results. In hair analysis, tramadol was by far the most prevalent opioid detected. Thirty-two percent screened positive for opioids, and of those, all but one were positive for tramadol. Ninety-eight percent reported problematic cannabis use. Significantly more opioid-positive patients also screened positive for other (noncannabis drugs, compared to nonopioid users. Sixty-four percent fulfilled criteria of DSM-IV psychiatric disorders, other than substance use disorders according to MINI. Fifty-three percent met the symptom criteria count of ADHD above cut-off level. Conclusion. In the present setting, tramadol, along with high rates of cannabis use, may represent a novel pattern of substance use among young treatment-seeking subjects with problematic substance use and high rates of concurrent psychiatric problems.

Full Text Available Abstract Background Nigeria ranks fourth among 22 high tuberculosis (TB burden countries. Although it reached 99% DOTS coverage in 2008, current case detection rate is 40%. Little is known about delays before the start of TB therapy and health-seeking behaviour of TB patients in rural resource-limited settings. We aimed to: 1 assess healthcare-seeking behaviour and delay in treatment of pulmonary TB patients, 2 identify the determinants of the delay in treatment of pulmonary TB. Methods We conducted a cross-sectional study of adult new pulmonary TB patients notified to the National Tuberculosis Control Programme (NTP by three rural (two mission/one public hospitals. Data on health-seeking and delays were collected using a standardised questionnaire. We defined patient delay as the interval (weeks between the onset of cough and the first visit to any health provider, and health system delay as the time interval (weeks between patient's first attendance to any health provider, and the onset of treatment. Total delay is the sum of both delays. Multiple linear regression models using nine exposure variables were built to identify determinants of delays. Results Of 450 patients (median age 30 years enrolled, most were males (55%, subsistent farmers (49%, rural residents (78%; and 39% had no formal education. About 84% of patients reported first consulting a non-NTP provider. For such patients, the first facilities visited after onset of symptoms were drug shops (79%, traditional healers (10%, and private hospitals (10%. The median total delay was 11 (IQR 9–16 weeks, patient delay 8 (IQR 8–12 and health system (HS delay 3 (IQR 1–4 weeks. Factors associated with increased patient delay were older age (P Conclusion Overall, TB treatment delays were high; and needs to be reduced in Nigeria. This may be achieved through improved access to care, further education of patients, engagement of informal care providers, and strengthening of existing public

Full Text Available Background. General practitioners are referring patients with codeine-related problems to specialist treatment facilities, but little is known about the addiction treatment providers, the kinds of treatment they provide, and whether training or other interventions are needed to strengthen this sector. Objectives. To investigate the perspectives of addiction treatment providers regarding treatment for codeine misuse or dependence. Method. Twenty addiction treatment providers linked to the South African Community Epidemiology Network on Drug Use and the South African Addiction Medicine Society were contacted telephonically and asked 20 questions. Results. While many participants had received training in pharmacological management of individuals with opioid dependence, only two had received specific training on codeine management. Between half and two-thirds of the treatment settings they worked in provided detoxification, pharmacotherapy, psychosocial treatment and aftercare. Very few treatment settings offered long-term treatment for codeine misuse and dependence. Participants indicated that over half of their codeine patients entered treatment for intentional misuse for intoxication, and dependence resulting from excessive or long-term use. The main barriers to patients entering treatment were seen as denial of having a problem, not being ready for change, mental health problems, stigma, and affordability of treatment. Participants identified a need for further training in how to manage withdrawal and detoxification, treatment modalities including motivational interviewing, and relapse prevention. Conclusions. Gaps in training among treatment providers need to centre on how to manage withdrawal from codeine use and detoxification, motivational interviewing and relapse prevention. Interventions are needed to address barriers to entering treatment, including user denial.

Broad spectrum detoxification: the major longevity assurance process regulated by insulin/IGF-1 signaling?

Science.gov (United States)

Gems, David; McElwee, Joshua J

2005-03-01

Our recent survey of genes regulated by insulin/IGF-1 signaling (IIS) in Caenorhabditis elegans suggests a role for a number of gene classes in longevity assurance. Based on these findings, we propose a model for the biochemistry of longevity assurance and ageing, which is as follows. Ageing results from molecular damage from highly diverse endobiotic toxins. These are stochastic by-products of diverse metabolic processes, of which reactive oxygen species (ROS) are likely to be only one component. Our microarray analysis suggests a major role in longevity assurance of the phase 1, phase 2 detoxification system involving cytochrome P450 (CYP), short-chain dehydrogenase/reductase (SDR) and UDP-glucuronosyltransferase (UGT) enzymes. Unlike superoxide and hydrogen peroxide detoxification, this system is energetically costly, and requires the excretion from the cell of its products. Given such costs, its activity may be selected against, as predicted by the disposable soma theory. CYP and UGT enzymes target lipophilic molecular species; insufficient activity of this system is consistent with age-pigment (lipofuscin) accumulation during ageing. We suggest that IIS-regulated longevity assurance involves: (a) energetically costly detoxification and excretion of molecular rubbish, and (b) conservation of existing proteins via molecular chaperones. Given the emphasis in this theory on investment in cellular waste disposal, and on protein conservation, we have dubbed it the green theory.

Overexpression of multiple detoxification genes in deltamethrin resistant Laodelphax striatellus (Hemiptera: Delphacidae in China.

Directory of Open Access Journals (Sweden)

Lu Xu

Full Text Available BACKGROUND: The small brown planthopper (SBPH, Laodelphax striatellus (Fallén, is one of the major rice pests in Asia and has developed resistance to multiple classes of insecticides. Understanding resistance mechanisms is essential to the management of this pest. Biochemical and molecular assays were performed in this study to systematically characterize deltamethrin resistance mechanisms with laboratory-selected resistant and susceptible strains of SBPH. METHODOLOGY/PRINCIPAL FINDINGS: Deltamethrin resistant strains of SBPH (JH-del were derived from a field population by continuously selections (up to 30 generations in the laboratory, while a susceptible strain (JHS was obtained from the same population by removing insecticide pressure for 30 generations. The role of detoxification enzymes in the resistance was investigated using synergism and enzyme activity assays with strains of different resistant levels. Furthermore, 71 cytochrome P450, 93 esterases and 12 glutathione-S-transferases cDNAs were cloned based on transcriptome data of a field collected population. Semi-quantitative RT-PCR screening analysis of 176 identified detoxification genes demonstrated that multiple P450 and esterase genes were overexpressed (>2-fold in JH-del strains (G4 and G30 when compared to that in JHS, and the results of quantitative PCR coincided with the semi-quantitative RT-PCR results. Target mutation at IIS3-IIS6 regions encoded by the voltage-gated sodium channel gene was ruled out for conferring the observed resistance. CONCLUSION/SIGNIFICANCE: As the first attempt to discover genes potentially involved in SBPH pyrethroid resistance, this study putatively identified several candidate genes of detoxification enzymes that were significantly overexpressed in the resistant strain, which matched the synergism and enzyme activity testing. The biochemical and molecular evidences suggest that the high level pyrethroid resistance in L. striatellus could be due to

Since not only malignant melanomas but also many kinds of human cancers, for example thyroid cancer and squamous cell carcinoma, synthesize their specific protein, much attention has been paid to the establishment of selective thermal neutron capture treatment of malignant melanoma as a prototype of such cancer cells. This paper presents 10 B chlorpromazine compounds and 10 B 1 -para-boronophenylalanine ( 10 B 1 -BPA) as tumor-seeking 10 B compounds which themselves possess selective affinity for the specific metabolic activity of the target cancer cells. An overview of the following studies on the effects of 10 B 1 -BPA in the thermal neutron capture treatment of melanoma is provided: 1) in vitro studies on specific enhanced melanoma cell killing effects of 10 B 1 -BPA; 2) in vivo studies on therapeutic effects of 10 B 1 -BPA using melanoma-bearing hamsters; and 3) preclinical therapeutic experiments using spontaneously occurring malignant melanoma in Duroc pig skin, including experiments in which melanoma was successfully cured.

2018-03-01

To identify viewpoints among men with depression about depression and its treatment, consider how these might influence help-seeking behaviour, and generate ideas for interventions and future research. Q methodology. Twenty-nine men with depression completed a Q sort by ranking a set of statements about depression and help-seeking according to their relative agreement with each statement. Factor analysis was used to identify viewpoints relating to male understandings of depression and help-seeking, which were interpreted in the context of participant characteristics and additional information from post-sorting interviews. A two-factor solution accounting for 45% of the total variance was considered the best fit for the data. The 2 factors were: (1) Help is available if you can get to the point of asking for it (34% of the variance) and (2) depression should be dealt with in private; help-seeking makes you vulnerable (11% of the variance). Participants who were significantly associated with both factors described a sense of shame, relating to their own or others' views that being depressed and help-seeking are in conflict with socially constructed 'masculine' values, such as strength and self-sufficiency. In the viewpoint represented by Factor 1, however, the benefits of help-seeking outweigh the negatives. In contrast, the viewpoint represented in Factor 2 holds that depression should remain a private struggle and that help-seeking is too risky a move to make. In order to access treatment, men must first recognize depression, then overcome considerable perceived and internalized stigma to ask for help. Improving public knowledge about the nature of depression; positive messages about the act of help-seeking, types of treatment available, and effectiveness of treatments; and work to overcome the challenges posed by long waiting times and other service constraints may increase rates of help-seeking, and represent areas for future research.

This paper is focussed on a techno-economical analysis comparing TiO{sub 2}-Persulfate and Photo-Fenton methods for Solar Detoxification of pesticides from an industrial point of view and considering the photocatalytic system coupled with a pesticide bottles recycling plant. The analysis is based on the experiments performed at PSA Solar Detox facility with 250 L of a mixture of 10 commercial pesticides, which have been treated with both photocatalytic methods in the same CPC-type reactor system. The initial TOC of the pollutants was 100 mg/L (considering not only the active ingredient but also the rest of the commercial formulation components) and the final TOC 10 mg/L (plant design parameters). Different experiments have been performed to optimize both treatments. In the experiments with Photo-Fenton 80% of the initial TOC were removed in 75 to 90 minutes and 90% in approximately 2 hours. In the experiment with TiO{sub 2}-Persulfate, 80% of the TOC was removed in 3 hours and 90% of the TOC after 4 hours. (authors)

2018-06-01

The symptoms of posttraumatic stress disorder (PTSD) and chronic pain are thought to interact to increase the severity and impact of both conditions, but the mechanisms by which they interact remain unclear. This study examines the relationship between PTSD and chronic pain and whether indices of Psychological Flexibility mediate the relationship between these 2 conditions. Standardized self-report measures of PTSD, pain severity, pain interference, depression, and psychological flexibility (pain-related acceptance, committed action, cognitive fusion, and values-based action) were obtained from 315 people seeking treatment for chronic pain who also reported at least 1 traumatic experience. People seeking treatment for chronic pain and reporting symptoms consistent with a current diagnosis of PTSD had significantly higher levels of pain severity, pain interference, depression, and cognitive fusion and lower levels of pain-related acceptance and committed action than those reporting symptoms below the diagnostic threshold for PTSD. Pain-related acceptance, committed action, cognitive fusion, and depression mediated the relationship between PTSD and pain severity/interference, with pain-related acceptance being the strongest mediator from the Psychological Flexibility model. Processes from the Psychological Flexibility model were identified as mediators of the relationship between PTSD and chronic pain in people seeking treatment for chronic pain. The Psychological Flexibility model may be useful as an overarching model to help understand the relationship between PTSD and chronic pain. It is possible that targeting pain-related acceptance, committed action, and cognitive fusion (among other processes) in the treatment of chronic pain may produce corresponding improvements in comorbid symptoms of PTSD when these are present and may reduce impacts of PTSD on outcomes of chronic pain. Conversely, targeting of these processes in the treatment of PTSD may produce similar

2015-01-01

Gaseous sulfide intrusion into seagrasses growing in sulfidic sediments causes little or no harm to the plant, indicating the presence of an unknown sulfide tolerance or detoxification mechanism. We assessed such mechanism in the seagrass Zostera marina in the laboratory and in the field...... as sulfate throughout the plant. We conclude that avoidance of sulfide exposure by reoxidation of sulfide in the rhizosphere or aerenchyma and tolerance of sulfide intrusion by incorporation of sulfur in the plant are likely major survival strategies of seagrasses in sulfidic sediments....

Bone-seeking radiopharmaceuticals in skeletal malignancy: evolution, not revolution

International Nuclear Information System (INIS)

MacFarlane, D.

2003-01-01

Many advanced malignancies are complicated by skeletal metastases, with attendant pain and disability. External beam radiotherapy is still the most effective treatment for isolated lesions. Bone-seeking radiopharmaceuticals were perceived as a means of delivering radiation to multiple lesions simultaneously. A wide variety of radioisotopes have been used in this endeavor, with myelosuppression being the most significant potential adverse effect. Benefits of treatment are modest, including a transient improvement in pain control and perhaps prolongation of the treatment-free period. This is best demonstrated in prostate cancer with lower responses by skeletal metastases from breast and lung cancers. However, the treatment is yet to produce any improvement in patient survival. Experimental approaches to improve treatment efficacy include combination with cytotoxic therapy, and administration earlier in the course of the disease. Bone seeking radiopharmaceuticals have been used in treatment of advanced osteosarcoma in humans and canines and achieved effective palliation. The myelosuppressive effects of these agents have been exploited in patients with multiple myeloma to assist in attaining myeloablation prior to stem cell transplantation. Development of more potent non-radiolabelled bisphosphonates and recognition of their antitumour effect against several tumours has sparked a recrudescence of interest in their use for bone metastases. Set against these developments, the role of bone-seeking radiopharmaceuticals in skeletal metastases may need to be redefined

Full Text Available Background The objective of this pilot study was to evaluate the feasibility of conducting a larger prospective cohort study, which will aim at determining the independent contribution of male and female lifestyle-related factors to assisted reproductive technology (ART success. The study also examined whether couples seeking fertility treatments present lifestyle-related factors that may interfere with their reproductive health. Materials and Methods This prospective pilot study was conducted in a fertility clinic between May 2015 and February 2016. Feasibility factors evaluated were recruitment rates, compliance with the protocol, retention rate and ART outcomes at six-month follow-up. Anthropometric profile and lifestyle habits of both partners were evaluated before the beginning of infertility treatments. Results We approached 130 eligible infertile couples. Among them, 32 (25% agreed to participate and 28 (88% complied with the protocol. At six-month follow-up, seven couples (25% did not start, or stop, infertility treatments and 13 couples (62% achieved a clinical pregnancy. Among the 28 couples included in the analyses, 16% of the partners were obese and 23% had abdominal obesity. The majority of the subjects were still drinking alcohol (84%. Sixty-eight percent of women needed improvement in their diet (vs. 95% of men, P=0.05 and none of them achieved the Canadian recommendations for physical activity (vs. 33% of men, P=0.001. Moreover, 35% of the partners had a poor sleep quality. Overall, women presented a worse reproductive health profile than men, with 3.1 and 2.4 out of seven adverse factors, respectively (P=0.04. Conclusion Conducting a large prospective cohort study in our fertility clinic will be feasible but recruitment and compliance with the protocol need to be improved. Many women and men seeking fertility treatments present unfavourable lifestyle-related factors that may explain, at least partially, their difficulties in

Patients (n = 194) with confirmed acute myocardial infarction (AMI) were interviewed to determine sociodemographic, clinical, social, behavioral, cognitive and emotional factors that contribute to delay in seeking treatment for their symptoms. Initial symptom experience was similar for men and women: both were most commonly at home when symptoms began; both were most commonly in the presence of their spouse or other family member; few patients (trouble others, and prior knowledge of thrombolytics. There was no difference in delay between men and women (median 3.08 versus 3.10 h), but there are important gender differences in the reasons patients delay and in their patterns of decision-making that may assist clinicians trying to tailor interventions.

Sex differences in methamphetamine seeking in rats: Impact of oxytocin

Previous evidence in an animal model of drug self-administration and drug seeking showed that acute oxytocin decreased methamphetamine (meth) seeking in male rats, suggesting potential clinical efficacy for the treatment of psychostimulant addiction. However, based on the well-established role of oxytocin in reproduction and pair bond formation, it is important to know how this effect extrapolates to females. Here, we tested whether oxytocin (1 mg/kg, IP) would decrease meth seeking in female...

2014-12-01

Gambling Disorder is associated with elevated rates of suicidal thoughts and acts. However, virtually nothing is known about suicidality in people with subsyndromal forms of gambling disorder. A total of 174 non-treatment seeking subjects were recruited for a study of impulsivity and met criteria for a subsyndromal form of DSM-5 gambling disorder (31.0 % females; mean age = 21.7 ± 3.61 years). Subjects were categorized as being 'at risk of suicide' or 'no suicide risk' based on the Mini-International Neuropsychiatric Interview (MINI). Those with and without suicidality were compared on clinical and cognitive measures. 32 (18.4 %) met MINI criteria for suicidality. Suicidality was significantly associated with mood and anxiety disorders, greater rates of nicotine consumption, and relative impairments in decision-making and cognitive flexibility. These findings suggest that decision-making impairments may be implicated in the development of both gambling problems and suicidality. Future work should address causality, neural correlates, and tailored suicide prevention strategies for people with, or at risk for, disordered forms of gambling.

To establish the prevalence of exposure to physical and sexual violence, mental health symptoms, and medical treatment-seeking behavior among three street-based subpopulation groups in Tegucigalpa, Honduras, and to assess the association between sociodemographic group, mental health indicators, and exposure to violence. An anonymous, cross-sectional survey among randomly selected street-based adolescents, adults, and commercial sex workers (CSWs) was undertaken at the end of 2010 in Tegucigalpa. Médecins Sans Frontières (MSF) mapped places where the study population gathers. Stratified probability samples were drawn for all groups, using two-stage random sampling. Trained MSF staff administered on-site standardized face-to-face questionnaires. Self-reported exposure to severe physical violence in the previous year was 20.9% among street-based adolescents, 28.8% among adults, and 30.6% among CSWs. For the physical violence event self-defined as most severe, 50.0% of the adolescents, 81.4% of the adults, and 70.6% of the CSWs sought medical treatment. Their exposure to severe sexual violence was 8.6%, 28.8%, and 59.2%, respectively. After exposure to the self-defined most severe sexual violence event, 14.3% of adolescents, 31.9% of adults, and 29.1% of CSWs sought treatment. Common mental health and substance abuse symptoms were highly prevalent and strongly associated with exposure to physical (odds ratio 4.5, P < 0.0001) and sexual (odds ratio 3.7, P = 0.0001) violence. Exposure to physical and sexual violence reached extreme levels among street-based subpopulations. Treatment-seeking behavior, particularly after severe sexual violence, was limited. The association of mental health and substance abuse symptoms with exposure to violence could lead to further victimization. Medical and psychological treatments targeting these groups are needed and could help decrease their vulnerability.

The purpose of the study was to assess the relationship between trauma-related sleep disturbance and physical health symptoms in treatment-seeking female rape victims. A total of 167 participants were assessed for PTSD symptoms, depression, sleep disturbance, and frequency of self-reported health symptoms. Results demonstrated that trauma-related sleep disturbance predicted unique variance in physical health symptoms after other PTSD and depression symptoms were controlled. The findings suggest that trauma-related sleep disturbance is one potential factor contributing to physical health symptoms in rape victims with PTSD.

2016-01-01

In the present study, the concentration of trace elements, total mercury (Hg) and selenium (Se) and mercury forms (MeHg, Hg inorg and HgSe) in the vulnerable coastal dolphins Pontoporia blainvillei and Sotalia guianensis were appraised and compared, using metallothioneins (MT) and glutathione (GSH) as biomarkers for trace element exposure. The trace element concentrations varied between muscle and liver tissues, with liver of all dolphin specimens showing higher Hg and Se concentrations than those found in muscle. Hg, MeHg and Hg inorg molar concentrations showed a clear increase with Se molar concentrations in the liver of both dolphins, and Se concentrations were higher than those of Hg on a molar basis. Se plays a relevant role in the detoxification of MeHg in the hepatic tissue of both dolphins, forming Hg-Se amorphous crystals in liver. In contrast, MT were involved in the detoxification process of Hg inorg in liver. GSH levels in P. blainvillei and S. guianensis muscle tissue suggest that these dolphins have different diving capacities. Muscle Hg concentrations were associated to this tripeptide, which protects dolphin cells against Hg stress. - Highlights: • Se aids in MeHg detoxification in dolphin liver, forming Hg-Se amorphous crystals. • MT was involved in liver Hg inorg detoxification and GSH was associated to muscle Hg. • Feeding habits seem to influence muscle GSH, suggesting different diving capacities. • MT, GSH and Se and Hg in different forms were investigated in two dolphin species. • Hepatic Hg, MeHg and Hg inorg increased with higher Se concentrations. - “Coastal dolphins showed Se-mediated detoxification of MeHg and MT-mediated detoxification of Hg inorg , while GSH suggests different diving capacities”.

2015-01-01

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

Previous evidence in an animal model of drug self-administration and drug seeking showed that acute oxytocin decreased methamphetamine (meth) seeking in male rats, suggesting potential clinical efficacy for the treatment of psychostimulant addiction. However, based on the well-established role of oxytocin in reproduction and pair bond formation, it is important to know how this effect extrapolates to females. Here, we tested whether oxytocin (1mg/kg, IP) would decrease meth seeking in female rats across various stages of the estrous cycle (Experiment 1). Freely cycling Long Evans female rats self-administered meth (IV) in 2-h daily sessions, followed by daily extinction sessions. Following extinction, rats received oxytocin (0, 0.3, or 1mg/kg, IP) 30min before a meth priming injection (1mg/kg, IP) to assess reinstatement of meth seeking. Next, we examined the effects of oxytocin on motivated meth- and sucrose-taking and seeking in male and female rats. In separate experiments, males and females self-administered meth (Experiment 2) or sucrose (Experiment 3) until responding was stabilized along a fixed ratio (FR) 5 schedule of reinforcement. Subsequently, rats received either oxytocin or vehicle prior to self-administration along a progressive ratio (PR) schedule of reinforcement. Rats were subsequently tested for cue-, meth-, and stress-induced reinstatement after pretreatment with oxytocin or vehicle. While oxytocin reduced meth seeking in females, we found that estrous cycle stage (as determined from vaginal cytology) did not influence meth-primed reinstatement or the ability of oxytocin to decrease reinstatement of meth seeking. Oxytocin reduced PR responding for meth only in females. Females responded more than males during cue-induced reinstatement of meth and sucrose seeking, and oxytocin reduced this responding only in meth females. In both sexes, oxytocin attenuated meth seeking in response to a meth prime and yohimbine (a pharmacological stressor). The

The Posttraumatic Stress Disorder Checklist (PCL-5; Weathers et al., 2013) was recently revised to reflect the changed diagnostic criteria for posttraumatic stress disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). We investigated the psychometric properties of PCL-5 scores in a large cohort (N = 912) of military service members seeking PTSD treatment while stationed in garrison. We examined the internal consistency, convergent and discriminant validity, and DSM-5 factor structure of PCL-5 scores, their sensitivity to clinical change relative to PTSD Symptom Scale-Interview (PSS-I; Foa, Riggs, Dancu, & Rothbaum, 1993) scores, and their diagnostic utility for predicting a PTSD diagnosis based on various measures and scoring rules. PCL-5 scores exhibited high internal consistency. There was strong agreement between the order of hypothesized and observed correlations among PCL-5 and criterion measure scores. The best-fitting structural model was a 7-factor hybrid model (Armour et al., 2015), which demonstrated closer fit than all other models evaluated, including the DSM-5 model. The PCL-5's sensitivity to clinical change, pre- to posttreatment, was comparable with that of the PSS-I. Optimally efficient cut scores for predicting PTSD diagnosis were consistent with prior research with service members (Hoge, Riviere, Wilk, Herrell, & Weathers, 2014). The results indicate that the PCL-5 is a psychometrically sound measure of DSM-5 PTSD symptoms that is useful for identifying provisional PTSD diagnostic status, quantifying PTSD symptom severity, and detecting clinical change over time in PTSD symptoms among service members seeking treatment.

Dassanayake, Ashlea F; Canales, Juan J

2018-04-03

There are currently no approved medications to effectively counteract the effects of methamphetamine (METH), reduce its abuse and prolong abstinence from it. Data accumulated in recent years have shown that a range of N-substituted benztropine (BZT) analogues possesses psychopharmacological features consistent with those of a potential replacement or "substitute" treatment for stimulant addiction. On the other hand, the evidence that antidepressant therapy may effectively prevent relapse to stimulant seeking is controversial. Here, we compared in rats the ability of the BZT analogue and high affinity dopamine (DA) reuptake inhibitor, JHW-007, and the antidepressant, trazodone, administered during extinction sessions after chronic METH self-administration, to alter METH-primed reinstatement of drug seeking. The data showed that trazodone produced paradoxical effects on lever pressing during extinction of METH self-administration, decreasing active, but increasing inactive, lever pressing. JHW-007 did not have any observable effects on extinction training. Importantly, JHW-007 significantly attenuated METH-primed reinstatement, whereas trazodone enhanced it. These findings lend support to the candidacy of selective DA uptake blockers, such as JHW-007, as potential treatments for METH addiction, but not to the use of antidepressant medication as a single therapeutic approach for relapse prevention.

Charlie Gard and the weight of parental rights to seek experimental treatment.

Science.gov (United States)

Birchley, Giles

2018-05-17

The case of Charlie Gard, an infant with a genetic illness whose parents sought experimental treatment in the USA, brought important debates about the moral status of parents and children to the public eye. After setting out the facts of the case, this article considers some of these debates through the lens of parental rights. Parental rights are most commonly based on the promotion of a child's welfare; however, in Charlie's case, promotion of Charlie's welfare cannot explain every fact of the case. Indeed, some seem most logically to extend from intrinsic parental rights, that is, parental rights that exist independent of welfare promotion. I observe that a strong claim for intrinsic parental rights can be built on arguments for genetic propriety and children's limited personhood. Critique of these arguments suggests the scope of parental rights remains limited: property rights entail proper use; non-personhood includes only a small cohort of very young or seriously intellectually disabled children and the uniqueness of parental genetic connection is limited. Moreover, there are cogent arguments about parents' competence to make judgements, and public interest arguments against allowing access to experimental treatment. Nevertheless, while arguments based on propriety may raise concerns about the attitude involved in envisioning children as property, I conclude that these arguments do appear to offer a prima facie case for a parental right to seek experimental treatment in certain limited circumstances. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Although community-based studies suggest equivalent levels of physical and psychological impairment by binge eating disorder (BED) in men and women, men with BED are still underrepresented in clinical studies. This study aimed to provide a comprehensive analysis of sex differences in biopsychosocial correlates of treatment-seeking obese patients with BED in primary care. One hundred-ninety obese adults (26% men) were recruited in primary care settings for a treatment study for obesity and BED. Very few significant sex differences were found in the developmental history and in current levels of eating disorder features, as well as psychosocial factors. Women reported significantly earlier age at onset of overweight and dieting and greater frequency of dieting. Men reported more frequent strenuous exercise. Men were more likely than women to meet criteria for metabolic syndrome; men were more likely to show clinically elevated levels of triglycerides, blood pressure, and fasting glucose levels. Despite few sex differences in behavioral and psychosocial factors, metabolic problems associated with obesity were more common among treatment-seeking obese men with BED than women. The findings highlight the importance of including men in clinical studies of BED and active screening of BED in obese men at primary care settings. © 2013.

Introduction Although sexual dysfunction is common after prostate cancer, men's decisions to seek help for sexual concerns are not well understood. Aim Describe predictors of actual prior help-seeking and intended future medical help-seeking for sexual dysfunction in prostate cancer survivors. Methods A cross-sectional survey of 510 prostate cancer survivors assessed masculine beliefs, attitudes, support/approval from partner/peer networks (subjective norm), and perceived control as predictors of medical help-seeking for sexual concerns. A theory of planned behavior (TPB) perspective was used to examine actual prior and planned future behavior and contributing factors. Statistical analyses included multiple and logistic regressions. Main Outcome Measures Intention to see a doctor for sexual advice or help in the next 6 months was measured using the intention subscale adapted from the Attitudes to Seeking Help after Cancer Scale. Prior help-seeking was measured with a dichotomous yes/no scale created for the study. Results Men were Mage 71.69 years (SD = 7.71); 7.54 years (SD = 4.68) post-diagnosis; received treatment(s) (58.1% radical prostatectomy; 47.1% radiation therapy; 29.4% hormonal ablation); 81.4% reported severe ED (IIED 0–6) and 18.6% moderate–mild ED (IIED 7–24). Overall, 30% had sought sexual help in the past 6 months, and 24% intended to seek help in the following 6 months. Prior help-seeking was less frequent among men with severe ED. Sexual help-seeking intentions were associated with lower education, prior sexual help-seeking, sexual importance/ priority, emotional self-reliance, positive attitude, and subjective norm (R2 = 0.56). Conclusion The TPB has utility as a theoretical framework to understand prostate cancer survivors' sexual help-seeking decisions and may inform development of more effective interventions. Masculine beliefs were highly salient. Men who were more emotionally self-reliant and attributed greater importance to sex

Honey constituents up-regulate detoxification and immunity genes in the western honey bee Apis mellifera.

2013-05-28

As a managed pollinator, the honey bee Apis mellifera is critical to the American agricultural enterprise. Recent colony losses have thus raised concerns; possible explanations for bee decline include nutritional deficiencies and exposures to pesticides and pathogens. We determined that constituents found in honey, including p-coumaric acid, pinocembrin, and pinobanksin 5-methyl ether, specifically induce detoxification genes. These inducers are primarily found not in nectar but in pollen in the case of p-coumaric acid (a monomer of sporopollenin, the principal constituent of pollen cell walls) and propolis, a resinous material gathered and processed by bees to line wax cells. RNA-seq analysis (massively parallel RNA sequencing) revealed that p-coumaric acid specifically up-regulates all classes of detoxification genes as well as select antimicrobial peptide genes. This up-regulation has functional significance in that that adding p-coumaric acid to a diet of sucrose increases midgut metabolism of coumaphos, a widely used in-hive acaricide, by ∼60%. As a major component of pollen grains, p-coumaric acid is ubiquitous in the natural diet of honey bees and may function as a nutraceutical regulating immune and detoxification processes. The widespread apicultural use of honey substitutes, including high-fructose corn syrup, may thus compromise the ability of honey bees to cope with pesticides and pathogens and contribute to colony losses.

Novel metabolic biomarkers related to sulfur-dependent detoxification pathways in autistic patients of Saudi Arabia

2011-11-01

Full Text Available Abstract Background Xenobiotics are neurotoxins that dramatically alter the health of the child. In addition, an inefficient detoxification system leads to oxidative stress, gut dysbiosis, and immune dysfunction. The consensus among physicians who treat autism with a biomedical approach is that those on the spectrum are burdened with oxidative stress and immune problems. In a trial to understand the role of detoxification in the etiology of autism, selected parameters related to sulfur-dependent detoxification mechanisms in plasma of autistic children from Saudi Arabia will be investigated compared to control subjects. Methods 20 males autistic children aged 3-15 years and 20 age and gender matching healthy children as control group were included in this study. Levels of reduced glutathione (GSH, total (GSH+GSSG, glutathione status (GSH/GSSG, glutathione reductase (GR, glutathione- s-transferase (GST, thioredoxin (Trx, thioredoxin reductase (TrxR and peroxidoxins (Prxs I and III were determined. Results Reduced glutathione, total glutathione, GSH/GSSG and activity levels of GST were significantly lower, GR shows non-significant differences, while, Trx, TrxR and both Prx I and III recorded a remarkably higher values in autistics compared to control subjects. Conclusion The impaired glutathione status together with the elevated Trx and TrxR and the remarkable over expression of both Prx I and Prx III, could be used as diagnostic biomarkers of autism.

Full Text Available Adolescents and young adults continue to remain the main focus of attention with regards to substance use related problems. There has been a limited focus on illicit substance use among middle aged and elderly population. The current study explored the changing trends of substance use among treatment seeking middle aged individuals (aged 40–60 years at a tertiary level drug dependence treatment centre. The questionnaire used to gather information for the study is a 19-item structured questionnaire. It includes information on various sociodemographic variables, “current,” and “ever” use of substance. Information is also collected on variables related to high risk injecting drug use and HIV status of the individuals. There has been consistent increase in the population of treatment seekers over five years. Over the five-year period, the absolute percentage increase in treatment seeking population is approximately 21%. Polysubstance use was found to increase significantly over five-study years (PTrend = 0.007.

The present study aims to investigate the impact of help-seeking self-stigma on the preference and intention to seek psychological treatment delivered online compared to face-to-face. This study uses survey data from two Swedish samples. Sample 1 consists of 267 students (78.7% women) with a mean age of 24.5 (SD = 6.1). Sample 2 consists of 195 primary care patients (56.9% women) with a mean age of 45.3 (SD = 17.7). The number of participants who preferred online treatment was higher if seeking psychological help for a perceived stigmatized problem compared to mental health problems in general. The odds ratios for choosing treatment online over face-to-face were 6.41, 95% CI [4.05, 10.14] in Sample 1 and 11.19, 95% CI [5.29, 23.67] in Sample 2. In addition, findings suggest that higher levels of help-seeking self-stigma predicted higher intention to seek treatment online compared to face-to-face. Our results suggest that online interventions may facilitate help-seeking among individuals deterred by stigma. © 2018 Wiley Periodicals, Inc.

The enzymatic hydrolysate produced from pretreated cellulosic solids substrate was combined with pretreatment hydrolysate before fermentation. Detoxification of the pretreatment hydrolysate using overliming or XAD-4 resin before being combined with enzymatic hydrolysate improved ethanol productivity in the first 4h of fermentation and overall fermentation efficiency. However, detoxification did not improve final ethanol yield because of sugar losses. The Y5 strain showed excellent ethanol productivities of 2.0 and 0.8g/L/h averaged over a period of 4 and 24h, respectively, in the undetoxified run. The furan metabolization rates of the Y5 strain were significantly higher for the undetoxified run than those for the detoxidfied runs, suggesting it can tolerate even higher furan concentrations than those studied. Preliminary mass and energy balances were conducted. SPORL produced an excellent monomeric sugar recovery value of about 85% theoretical and a net energy output of 4.05GJ/ton wood with an ethanol energy production efficiency of 178% before distillation.

Relapse to cocaine use is a major problem in the clinical treatment of cocaine addiction. Antidepressants have been studied for their therapeutic potential to treat cocaine use disorder. Research has suggested that antidepressants attenuate both drug craving and the re-acquisition of drug-seeking and drug-taking behaviors. This study examined the efficacy of mirtazapine, an antidepressant/anxiolytic, in decreasing cocaine seeking in rats. We used the cocaine self-administration paradigm to assess the effects of mirtazapine on rats trained to self-administer cocaine or food under a fixed-ratio schedule. Mirtazapine (30 mg/kg, i.p.) was administered during extinction. Mirtazapine significantly attenuated non-reinforced lever-press responses during extinction. Moreover, the mirtazapine dosed for 30 days during extinction produced sustained attenuation of lever-press responses during re-acquisition of cocaine self-administration, without changing food-seeking behavior. Our results showed that mirtazapine attenuated the re-acquisition of cocaine-seeking responses. Our study pointed to the efficacy of mirtazapine in reducing the risk of drug relapse during abstinence, suggesting for its potential use as a novel pharmacological agent to treat drug abuse.

Full Text Available Objectives. (1 To assess the current presence of ADHD symptoms among patients seeking treatment for gambling disorder; (2 to explore clinical and sociodemographic differences between patients who score high and low on the measure of ADHD symptoms; (3 to analyze whether the presence of ADHD symptoms is associated with more severe psychopathology and with specific personality traits; (4 to analyze the mediating role of ADHD symptoms in the relationship between novelty seeking and gambling severity. Method. A total of 354 consecutive patients were administered an extensive battery assessing gambling behavior, psychopathology, and personality traits. Results. Male and female gamblers did not differ significantly in their mean scores on the ADHD measure. However, younger participants aged 18–35 scored higher. Higher ADHD scores were also associated with greater severity of gambling disorder and more general psychopathology. Regarding personality traits, high persistence and self-directedness were negatively related to ADHD scores, while in women alone a positive correlation was found between ADHD scores and scores on harm avoidance and self-transcendence. Conclusion. The presence of ADHD symptoms in both male and female gambling disorder patients may act as an indicator of the severity of gambling, general psychopathology, and dysfunctional personality traits.

Traumatic events often occur in workplace settings and can lead to stress reactions such as Post-Traumatic Stress Disorder (PTSD). One such workplace is the transportation industry, where employees are often exposed to trauma. However, extant research shows that a considerable proportion of people with PTSD do not seek specialty mental health treatment. In this qualitative study, we sought to better understand the experience of a traumatic event at work and the barriers and motivating factors for seeking mental health treatment. Twenty-nine Toronto Transit Commission (TTC) employees participated in a one-on-one interview, 18 soon after the traumatic event and 11 after entering a specialized treatment program. Semi-structured, one-on-one interviews were conducting using qualitative description and analyzed using content analysis. Participants described emotional responses after the trauma such as guilt, anger, disbelief as particularly difficult, and explained that barriers to seeking help included the overwhelming amount and timing of paperwork related to the incident as well as negative interactions with management. Motivating factors included family and peer support, as well as financial and emotional issues which persuaded some to seek help. Seeking treatment is a multifactorial process. Implications and recommendations for the organization are discussed.

Schistosomiasis is a chronic and debilitating parasitic disease acquired through contact with infested freshwater. An essential component of its control is passive case finding, which, in order to be effective, requires a detailed understanding of health-seeking behaviour. This study aimed to systematically review evidence on health-seeking behaviour for schistosomiasis, in order to determine factors influencing use or non-use of modern health services for the infection. Quantitative, qualitative and mixed method studies reporting on factors related to seeking treatment from modern health services for schistosomiasis were obtained, combining electronic and hand searching. Data extraction and quality assessment of the included articles were performed, with all studies qualitatively analysed using thematic synthesis. A total of 19 studies were included in the review. Six themes were identified from the analysis: biomedical knowledge on schistosomiasis, perceptions of modern treatment and health services, financial considerations of treatment, perceptions on the symptoms, stigma of the infection, and physical location and community. These findings were consistent across studies of different design, setting and quality. Many of the themes identified echo existing literature on health-seeking behaviour. The synthesis also highlighted the role of stigma, and aspects of the physical location and community that may affect treatment-seeking for schistosomiasis. Health education programmes that intend to improve the utilisation of modern health services for the infection need to acknowledge the multiple determinants influencing their use. Future research should move beyond describing health-seeking behaviour to identifying the factors that underlay such behaviour.

Detoxification and sensing mechanisms are of similar importance for Cd resistance in Caenorhabditis elegans

Full Text Available The present study employed mass spectrometry (ICP-MS to measure the internal cadmium concentrations (Cdint in Caenorhabditis elegans to determine Cd uptake from a Cd-containing environment as well as Cd release under Cd-free conditions. To analyze the functional role of several ATP binding cassette (ABC transporters (e.g., HMT-1 and MRP-1 and phytochelatin synthase (PCS, we compared wild-type (WT and different mutant strains of C. elegans. As a pre-test on selected mutant strains, several time-resolved experiments were performed to determine the survival rate and avoidance behavior of C. elegans under Cd stress, which confirmed the already known Cd sensitivity of the deletion mutants mrp-1Δ, pcs-1Δ, and hmt-1Δ. In addition, these experiments revealed flight reactions under Cd stress to be almost completely absent in mrp-1Δ mutants. The ICP-MS studies showed Cd uptake to be significantly higher in mrp-1Δ and WT than in hmt-1Δ. As Cd is ingested with food, food refusal due to very early Cd stress and its perception was likely the reason for the reduced Cd uptake of hmt-1Δ. Cd release (detoxification was found to be maximal in mrp-1Δ, minimal in hmt-1Δ, and intermediate in WT. High mortality under Cd stress, food refusal, and minimal Cd release in the case of hmt-1Δ suggest a vital importance of the HMT-1/PCS-1 detoxification system for the survival of C. elegans under Cd stress. High mortality under Cd stress, absence of an avoidance behavior, missing food refusal, and maximal Cd release in the case of mrp-1Δ indicate that MRP-1 is less important for Cd detoxification under severe stress, but is probably important for Cd perception. Accordingly, our results suggest that the survival of WT under Cd stress (or possibly other forms of metal stress primarily depends on the function of the HMT-1/PCS-1 detoxification system and the presence of a sensing mechanism to control the uptake of Cd (or other metals, which keeps internal Cd (or metal

Anxiety disorders represent the single largest mental health problem in the United States [Greenberg et al., 1999. J Clin Psychiatry 60:427-435; Rice and Miller, 1998. Br J Psychiatry 173:4-9]. However most individuals with anxiety disorders never seek treatment [Henderson et al., 2002. Can J Psychiatry 47:819-824; Mojtabai et al., 2002. Arch Gen Psychiatry 59:77-84; Roness et al., 2005. Acta Psychiatr Scand 111:51-58]. Deficits in the ability to recognize anxiety disorders and beliefs about them, (i.e., "mental health literacy") may contribute to low levels of help seeking. Survey data assessing mental health literacy for multiple anxiety disorders and for depression were collected from 284 undergraduate students enrolled in psychology courses at a public university in the United States. Specifically, respondents were presented with vignettes portraying individuals experiencing various forms of mental illness and were asked to label the disorder, its cause and whether or not they would recommend treatment. Findings showed that social phobia and obsessive compulsive disorder (OCD) were associated with recognition rates that were generally high and similar to depression (approximately 80%). In contrast, less than half of the respondents labeled panic disorder or generalized anxiety disorder (GAD) correctly. Symptoms of OCD were attributed to mental illness by approximately 50% of respondents, but such attributions were rare for the other anxiety disorders studied (anxiety disorders and according to perceptions of the causes of symptoms. Given that the current sample was well-educated young adults, mental health literacy of the general public may be even lower.

Eating disorders which embrace anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified can be life-threatening due to general medical complications; however, the diagnosis of eating disorder is often delayed due to a low suspicion index. Gastroenterologists are health care providers who may come into contact with patients with undiagnosed eating disorders; it has been previously demonstrated that patients with eating disorders frequently have a significant association with functional dyspepsia. Signs of dental erosion have been described in patients with eating disorders; hence, they may help to identify eating disorders in patients who present with functional dyspepsia and deny having an eating disorder. In this report we describe three cases (a 25-year-old white woman, a 24-year-old white woman, and a 40-year-old white man) with undiagnosed eating disorders, in which a more comprehensive approach, such as the recognition of dental erosion joined with a careful gastrointestinal investigation, was performed to reach a final diagnosis of an eating disorder. The screening for dental erosion in patients seeking or receiving medical treatment for dyspeptic symptoms in a gastrointestinal out-patient clinic could be an aid for gastroenterologists to recognize the presence of an underlying eating disorder. A close collaboration with dentists, in addition to psychiatrists, could provide a more favorable treatment outcome.

Prompt antiretroviral therapy (ART) initiation maximises the therapeutic and prevention benefits of a treat-all strategy for HIV therapy. Using in-depth semi-structured interviews with men and women 18 years and older (N = 41), who were highly motivated and seeking treatment, this study examined salient factors that were associated with delays in treatment access and initiation. Results revealed clinic-related barriers including an onerous, inefficient multi-step process to initiate ART. Participants experienced additional delays due to difficulties accessing care (e.g., being turned away from clinics and referred elsewhere) and health service challenges. Health service challenges included difficulty securing appointments, administrative mistakes (especially lost clinic folders and test results), difficulty navigating the clinic system (e.g., failure to collect a queue card or waiting for incorrect services) and negative clinic-patient interactions. Overall, there was a pervasive negative perception of clinics. Results strongly indicate the need for more patient-centred models of care and the need to reduce unnecessary patient-days at clinics.

Developing countries such as Ghana have very poor childhood cancer survival rates. There is a need to determine reasons for late presentation and treatment abandonment which are major causes of poor survival. Understanding these issues could inform effective strategies for childhood cancer control in resource-constrained settings. To explore factors influencing parental decision-making for children with cancer in Ghana with regard to health seeking and retention in treatment, in order to provide information that will guide Public Health interventions for childhood cancer control. This exploratory qualitative study was conducted based on an interpretative epistemology using a social constructionist approach. Purposive sampling of parents attending the Paediatric Oncology Unit, Korle Bu Teaching Hospital in Accra, Ghana was undertaken. Twelve semi-structured moderate interviews and two small focus group discussions with a total of seven participants were undertaken. Data analysis was through thematic content analysis. Five major themes emerged. Knowledge and perceptions revealed a total lack of appropriate knowledge prior to diagnosis. Health-seeking behaviour was determined by interplay of individual and environmental factors. Orthodox medical treatment was largely perceived favourably. The impact of cancer on parents and children included psychological, physical and socioeconomic effects. Financial, spiritual and psychosocial support helped in coping. Parents recommended public education and health financing to address the major barriers. Broad social determinants and experiences influence parental decision making for children with cancer. This implies Health Promotion strategies with multi-sectorial involvement will be required for effective implementation of the National Strategy for Cancer Control. Funded by authors.

Faecal incontinence (FI) is not a common presenting complaint in Malaysia, and little has been published on this topic. Since it is a treatable condition, a greater understanding of factors contributing to healthseeking behaviour is needed in order to plan effective provision of services. A survey of 1000 patients and accompanying relatives, visiting general surgical and obstetrics and gynaecology clinics for matters unrelated to FI, was conducted at University Malaya Medical Centre between January 2009 and February 2010. A follow-up regression analysis of the 83 patients who had FI, to identify factors associated with health-seeking behaviour, was performed. Variables identified through univariate analysis were subjected to multivariate analysis to determine independence. Reasons for not seeking treatment were also analysed. Only eight patients (9.6%) had sought medical treatment. On univariate analysis, the likelihood of seeking treatment was significantly higher among patients who had more severe symptoms (OR 30.0, p=0.002), had incontinence to liquid stool (OR 3.83, p=0.002) or when there was an alteration to lifestyle (OR: 17.34; p<0.001). Nevertheless, the only independently-associated variable was alteration in lifestyle. Common reasons given for not seeking treatment was that the condition did not affect patients' daily activities (88.0%), "social taboo" (5.3%) and "other" reasons (6.7%). Lifestyle alteration is the main driver of healthseeking behaviour in FI. However, the majority do not seek treatment. Greater public and physician-awareness on FI and available treatment options is needed.

To characterize treatment-seeking young adults (16-25 years) with severe obesity, particularly mental health problems. Cross-sectional study of 165 participants (132 women, 33 men) with BMI ≥35 kg/m2 or ≥30 kg/m2 with comorbidities, enrolling in a multidisciplinary obesity treatment program. Data collection at admission of present and life-time health issues including symptomatology of anxiety, depression (Hospital Anxiety and Depression Scale) and attention-deficit/hyperactivity disorder (Adult ADHD Self-Report scale); self-esteem (Rosenberg Self-Esteem Scale), suicide attempts, health-related quality of life (Short Form-36 Health Survey), psychosocial functioning related to obesity (Obesity-related Problems Scale), cardiorespiratory fitness (Astrand's bicycle ergometer test), somatic and psychiatric co-morbidities, cardiometabolic risk factors, and micronutritional status. We used multiple regression analysis to identify variables independently associated with present anxiety and depressive symptomatology. Mean body mass index was 39.2 kg/m2 (SD = 5.2). We found evidence of poor mental health, including present psychiatric diagnoses (29%), symptomatology of anxiety (47%), depression (27%) and attention-deficit/hyperactivity disorder (37%); low self-esteem (42%), attempted suicide (12%), and low quality of life (physical component score = 46, SD = 11.2; mental component score = 36, SD = 13.9, Pobesity-related problems (P = 0.018). The prevalence of type 2 diabetes was 3%, and hypertension 2%. Insulin resistance was present in 82%, lipid abnormality in 62%, and poor cardiorespiratory fitness in 92%. Forty-eight percent had at least one micronutritional deficiency, vitamin D being the most common (35%). A wide range of health issues, including quite severe mental health problems, was prevalent in treatment-seeking young adults with severe obesity. These are likely to constitute a major treatment challenge, including options relating to bariatric surgery.

Attitudes toward menarche and menstruation are largely influenced by sociological, cultural, and family environmental factors. Recognizing the influential effects that these factors might have on shaping adolescents' attitudes is crucial in designing a more effective means of transmitting health information. This study aimed to gather an in-depth understanding of perceptions, impacts, and treatment seeking on menstruation-related issues from an ethnically mixed group of rural and urban girls. In total, 27 focus group discussions (172 participants) were conducted between November 2008 and April 2009. Participants were adolescent girls aged 13-19 years, recruited from 7 public secondary schools in the Federal Territory of Kuala Lumpur and 4 public secondary schools from the rural districts of Kelantan, in Malaysia. Many participants revealed that they were not given or had not received detailed information about the mechanism or physiology of menstruation prior to its onset. Thus, many described the onset of menarche as shocking, an event for which they were unprepared, and which has had a tremendous impact on their emotions. More positive acceptance of menarche was reported in the urban than with the rural groups. Despite the high prevalence of premenstrual syndrome and dysmenorrhea, participants across urban-rural and ethnic groups perceived the problems as completely normal, hence they relied on self-care methods and did not want to seek professional treatment. More rural girls compared to urban girls were embarrassed to talk to their mothers or consult their physicians regarding menstruation-related problems. Menstruation-related education would have a positive impact in improving adolescent girls' knowledge and in nurturing a positive attitude toward menstruation-related matters at home, at school, and in the community.

The European spurge hawkmoth, Hyles euphorbiae (Lepidoptera, Sphingidae), has been intensively studied as a model organism for insect chemical ecology, cold hardiness and evolution of species delineation. To understand species isolation mechanisms at a molecular level, this study aims at determining genetic factors underlying two adaptive ecological trait candidates, phorbol ester (TPA) detoxification and seasonal cold acclimation. A draft transcriptome of H. euphorbiae was generated using Illumina sequencing, providing the first genomic resource for the hawkmoth subfamily Macroglossinae. RNA expression levels in tissues of experimental TPA feeding larvae and cooled pupae was compared to levels in control larvae and pupae using 26 bp RNA sequence tag libraries (DeepSuperSAGE). Differential gene expression was assessed by homology searches of the tags in the transcriptome. In total, 389 and 605 differentially expressed transcripts for detoxification and cold hardiness, respectively, could be identified and annotated with proteins. The majority (22 of 28) of differentially expressed detox transcripts of the four 'drug metabolism' enzyme groups (cytochrome P450 (CYP), carboxylesterases (CES), glutathione S-transferases (GST) and lipases) are up-regulated. Triacylglycerol lipase was significantly over proportionally annotated among up-regulated detox transcripts. We record several up-regulated lipases, GSTe2, two CESs, CYP9A21, CYP6BD6 and CYP9A17 as candidate genes for further H. euphorbiae TPA detoxification analyses. Differential gene expression of the cold acclimation treatment is marked by metabolic depression with enriched Gene Ontology terms among down-regulated transcripts almost exclusively comprising metabolism, aerobic respiration and dissimilative functions. Down-regulated transcripts include energy expensive respiratory proteins like NADH dehydrogenase, cytochrome oxidase and ATP synthase. Gene expression patterns show shifts in carbohydrate

Tramadol is a synthetic opiate and a centrally acting weak m-opioid receptor agonist. The potential advantages of tramadol include ease of administration, low abuse potential, and being nonscheduled. This study compared tramadol and buprenorphine for controlling withdrawal symptoms in patients with opioid dependence syndrome. Consenting male subjects between 20 and 45 years of age who fulfilled the ICD-10-DCR criteria for opiate dependence syndrome were randomly assigned in a double-blind, double-dummy placebo-controlled trial for detoxification. Those with multiple drug dependence, abnormal cardiac, renal and hepatic functions, psychosis, or organic mental illness were excluded. Assessments included Subjective Opiate Withdrawal Scale (SOWS), Objective Opiate Withdrawal Scale (OOWS), Visual Analog Scale (VAS), and Side Effect Check List. Subjects were evaluated daily and study duration was 10 days. Sixty two subjects were enrolled. The mean SOWS and OOWS and VAS were significantly lower in the buprenorphine group on second and third day of detoxification as compared to the tramadol group. Although the retention rate was higher for buprenorphine group throughout the study, when compared with tramadol the difference was not significant on any day. Three subjects in the tramadol group had seizures. Tramadol was found to have limited detoxification efficacy in moderate to severe opioid withdrawal and substantial risk of seizures as compared to buprenorphine. Further studies are warranted to examine its efficacy in mild opioid withdrawal symptoms and its potential use in outpatient settings where its administration advantages may be valuable.

Full Text Available Abstract Background Although cervical cancer is a leading cause of cancer related morbidity and mortality among women in Ethiopia, there is lack of information regarding the perception of the community about the disease. Methods Focus group discussions were conducted with men, women, and community leaders in the rural settings of Jimma Zone southwest Ethiopia and in the capital city, Addis Ababa. Data were captured using voice recorders, and field notes were transcribed verbatim from the local languages into English language. Key categories and thematic frameworks were identified using the health belief model as a framework, and presented in narratives using the respondents own words as an illustration. Results Participants had very low awareness of cervical cancer. However, once the symptoms were explained, participants had a high perception of the severity of the disease. The etiology of cervical cancer was thought to be due to breaching social taboos or undertaking unacceptable behaviors. As a result, the perceived benefits of modern treatment were very low, and various barriers to seeking any type of treatment were identified, including limited awareness and access to appropriate health services. Women with cervical cancer were excluded from society and received poor emotional support. Moreover, the aforementioned factors all caused delays in seeking any health care. Traditional remedies were the most preferred treatment option for early stage of the disease. However, as most cases presented late, treatment options were ineffective, resulting in an iterative pattern of health seeking behavior and alternated between traditional remedies and modern treatment methods. Conclusion Lack of awareness and health seeking behavior for cervical cancer was common due to misconceptions about the cause of the disease. Profound social consequences and exclusion were common.

While a growing literature has addressed the psychological consequences of torture and refugee trauma, most studies have focused on homogeneous samples drawn from a single region. Thus, relatively little research has attempted to identify demographic or experiential factors that might help explain different levels of distress in these individuals. We measured depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms in a convenience sample of refugees and survivors of torture seeking treatment in a torture treatment program (N = 325). We found 81.1% of patients had clinically significant anxiety, 84.5% had clinically significant depressive symptoms, and 45.7% had significant PTSD symptoms. Regression analyses revealed that anxiety and depressive symptom were significant higher among women (beta = .08, p = 0.02 and beta = .22, p = 0.0001 for anxiety and depression respectively) and those who reported death threats as part of their traumatic experiences (beta = .10, p = 0.033 and beta = .12, p = 0.036 respectively). Symptoms of PTSD were also predicted by death threats (beta = .22, p = 0.03), but were also influenced by the experience of rape (beta = .33, p < 0.001), family torture experiences (beta = .23, p = 0.022), religion (beta = .21, p = 0.03), and age (beta = -.18, p = 0.004). The clinical implications of these results are discussed.

Full Text Available Objective. The public has a high interest in seeking personal genetic information, which holds implications for health information seeking research and health care policy. Rapid advances in cancer genetics research promise early detection, prevention and treatment, yet consumers may have greater difficulty finding and using the information they may need to make informed decisions regarding their personal health and the future of their families. Design. A statewide telephone survey was conducted of non-institutionalized Kentucky residents 18 years of age or older to investigate factors associated with the intention to seek cancer genetics information, including the need for such information seeking help. Results. The results show that intention to seek cancer genetics information, if testing were readily available, is moderately high (62.5% of those responding; n=835, and that status as a racial minority, the perception that cancer runs in one's family, and frequent worrying about cancer risk are statistically significant predictors of intent to seek genetics information. Conclusion. . We argue that an already complex health information environment will be even more difficult for individuals to navigate as genetic research becomes more ubiquitous in health care. An increase in demand for genetics information in various forms, as suggested by these results and those of other studies, implies that enduring intervention strategies are needed to help individuals acquire necessary health information literacy skills, with special attention given to racial minorities.

Although effective treatment is available for a variety of mental disorders, the treatment and help-seeking gap remains high. One of the main obstacles to help-seeking behaviour is prevailing stigmatizing attitudes. To examine attitudes within the general population towards seeking professional help in times of mental distress. A representative general population survey ( N = 594) was conducted in Slovenia by means of an Internet-based questionnaire, covering data on demographic variables and attitudes towards help-seeking behaviour. More stigmatizing attitudes towards help-seeking behaviour were found in men, single persons, those of a younger age and lower educational achievement and in respondents coming from regions with a high suicide rate. Furthermore, 52.50% of the total sample have had an experience with psychological problems, yet only 41.50% of those have sought professional help. Experience with help-seeking behaviour in the past was associated with less stigmatizing attitudes. Knowledge and understanding of mental health problems are necessary prerequisites to seeking help, but not the only ones. To improve help-seeking behaviour, it is also important to combat stigmatizing attitudes. Additionally, destigmatizing campaigns should also focus on social norms.

The effect of web based depression interventions on self reported help seeking: randomised controlled trial [ISRCTN77824516

2006-04-01

Full Text Available Abstract Background To date, there has been very little work investigating behaviour changes induced by interventions that are designed to increase help seeking. The present paper examines the effects of two Internet depression websites on help seeking. Methods 414 individuals with elevated scores on a depression assessment scale were randomly allocated to a depression information website, a cognitive-behavioural skills training website (CBT or an attention control condition. Reports of help seeking for specific treatments, from specific sources and for categories of treatments were assessed. Results Relative to the control, the depression information site was associated with decreases in seeking support from friends and family, the use of music and of everyday treatments and no increase in seeking evidence based interventions. The CBT site was associated with the report of help seeking for CBT, massage and exercise. Conclusion Methods to encourage the use of evidence-based treatments need further research to determine whether the assistance sought is evidence based and whether there are unintended effects.

Beyond cellular detoxification: a plethora of physiological roles for MDR transporter homologs in plants

Science.gov (United States)

Remy, Estelle; Duque, Paula

2014-01-01

Higher plants possess a multitude of Multiple Drug Resistance (MDR) transporter homologs that group into three distinct and ubiquitous families—the ATP-Binding Cassette (ABC) superfamily, the Major Facilitator Superfamily (MFS), and the Multidrug And Toxic compound Extrusion (MATE) family. As in other organisms, such as fungi, mammals, and bacteria, MDR transporters make a primary contribution to cellular detoxification processes in plants, mainly through the extrusion of toxic compounds from the cell or their sequestration in the central vacuole. This review aims at summarizing the currently available information on the in vivo roles of MDR transporters in plant systems. Taken together, these data clearly indicate that the biological functions of ABC, MFS, and MATE carriers are not restricted to xenobiotic and metal detoxification. Importantly, the activity of plant MDR transporters also mediates biotic stress resistance and is instrumental in numerous physiological processes essential for optimal plant growth and development, including the regulation of ion homeostasis and polar transport of the phytohormone auxin.

This study examined patterns of treatment entry by Puerto Rican, Central American, Dominican, and other Latino male injection drug users (IDUs) in the state of Massachusetts over the time period 1996-2002. Specifically, it explored whether these populations had different patterns relative to three paths: entry into detoxification only, entry into residential treatment, or entry into methadone maintenance. Using a state-level MIS dataset on all substance abuse treatment entries to all licensed treatment programs, bi-variate and logistic regression methods were employed to examine patterns of drug treatment utilization among Latino men residing in Massachusetts. Three logistic regression models, which controlled for age, education, homelessness, employment, history of mental health treatment, health insurance, criminal justice involvement, having injected drugs in the past month, and number of treatment entries, indicated that Puerto Rican men were significantly less likely to only use detoxification services and residential treatment services, and significantly more likely to enter methadone maintenance compared to Latino men from Central American, Dominican, or other Latino backgrounds. For example, Central American men were 2.4 times more likely to enter only detoxification programs and 54% less likely to enter methadone maintenance programs than Puerto Rican male IDUs. For program planning, include the need to (a) develop varied drug treatment services to meet the needs of non-homogenous Latino groups within the population, (b) tailor outreach efforts to effectively reach all Latino groups, and (c) increase awareness among practitioners of differential patterns of treatment utilization.

Since common ground is pivotal to collaboration, this paper proposes to define collaborative information seeking as the combined activity of information seeking and collaborative grounding. While information-seeking activities are necessary for collaborating actors to acquire new information......, the activities involved in information seeking are often performed by varying subgroups of actors. Consequently, collaborative grounding is necessary to share information among collaborating actors and, thereby, establish and maintain the common ground necessary for their collaborative work.

Habitual alcohol seeking: modeling the transition from casual drinking to addiction

Science.gov (United States)

Barker, Jacqueline M; Taylor, Jane R

2014-01-01

The transition from goal-directed actions to habitual ethanol seeking models the development of addictive behavior that characterizes alcohol use disorders. The progression to habitual ethanol-seeking behavior occurs more rapidly than for natural rewards, suggesting that ethanol may act on habit circuit to drive the loss of behavioral flexibility. This review will highlight recent research that has focused on the formation and expression of habitual ethanol seeking, and the commonalities and distinctions between ethanol and natural reward-seeking habits, with the goal of highlighting important, understudied research areas that we believe will lead toward the development of novel treatment and prevention strategies for uncontrolled drinking.

Many people with mental illness do not seek professional help. Beliefs about the causes of their current health problem seem relevant for initiating treatment. Our aim was to find out to what extent the perceived causes of current untreated mental health problems determine whether a person considers herself/himself as having a mental illness, perceives need for professional help and plans to seek help in the near future. In a cross-sectional study, we examined 207 untreated persons with a depressive syndrome, all fulfilling criteria for a current mental illness as confirmed with a structured diagnostic interview (Mini International Neuropsychiatric Interview). The sample was recruited in the community using adverts, flyers and social media. We elicited causal explanations for the present problem, depression literacy, self-identification as having a mental illness, perceived need for professional help, help-seeking intentions, severity of depressive symptoms (Patient Health Questionnaire - Depression), and whether respondents had previously sought mental healthcare. Most participants fulfilled diagnostic criteria for a mood disorder (n = 181, 87.4%) and/or neurotic, stress-related and somatoform disorders (n = 120, 58.0%) according to the ICD-10. N = 94 (45.4%) participants had never received mental health treatment previously. Exploratory factor analysis of a list of 25 different causal explanations resulted in five factors: biomedical causes, person-related causes, childhood trauma, current stress and unhealthy behaviour. Attributing the present problem to biomedical causes, person-related causes, childhood trauma and stress were all associated with stronger self-identification as having a mental illness. In persons who had never received mental health treatment previously, attribution to biomedical causes was related to greater perceived need and stronger help-seeking intentions. In those with treatment experience, lower attribution to person-related causes and

To evaluate the associations between weight-based stigmatization, psychological distress, and binge eating behavior in a treatment-seeking obese sample. Ninety-three obese adults completed three questionnaires: 1) Stigmatizing Situations Inventory, 2) Brief Symptoms Inventory, and 3) Binge Eating Questionnaire. Correlational analyses were used to evaluate the association between stigmatizing experiences, psychological distress and binge eating behavior. Stigmatizing experiences predicted both binge eating behavior (R(2)=.20, p<.001) and overall psychological distress (R(2)=.18, p<.001). A substantial amount of the variance in binge eating predicted by weight-based stigmatization was due to the effect of psychological distress. Specifically, of the 20% of the variance in binge eating accounted for by stigmatizing experiences, between 7% and 34% (p<.01) was due to the effects of various indicators of psychological distress. These data suggest that weight-based stigmatization predicts binge eating behavior and that psychological distress associated with stigmatizing experiences may be an important mediating factor.

Detoxification of Pesticide-Containing Wastewater with FeIII, Activated Carbon and Fenton Reagent and Its Control Using Three Standardized Bacterial Inhibition Tests

2017-12-01

Full Text Available Discharge of toxic industrial wastewaters into biological wastewater treatment plants may result in inhibition of activated sludge bacteria (ASB. In order to find an appropriate method of detoxification, the wastewater of a pesticide-processing plant in Vietnam was treated with three different methods (FeIII, powdered activated carbon (PAC, Fenton (FeII/H2O2 analyzing the detoxification effect with the nitrification inhibition test (NIT, respiration inhibition test (RIT and luminescent bacteria test (LBT. The heterotrophic ASB were much more resistant to the wastewater than the autotrophic nitrificants. The NIT turned out to be more suitable than the RIT since the NIT was less time-consuming and more reliable. In addition, the marine Aliivibrio fischeri were more sensitive than the nitrificants indicating that a lack of inhibition in the very practical and time-efficient LBT correlates with a lack of nitrification inhibition. With 95%, the Fenton method showed the highest efficiency regarding the chemical oxygen demand (COD removal. Although similar COD removal (60–65% was found for both the FeIII and the PAC method, the inhibitory effect of the wastewater was reduced much more strongly with PAC. Both the NIT and the LBT showed that the PAC and Fenton methods led to a similar reduction in the inhibitory effect.

Atmospheric pressure non-thermal dielectric barrier discharge (DBD) plasma generated by helium gas at high voltage and input power of about 50 W was first applied to detoxification of Jatropha curcas phorbol esters (J. PEs) as well as standard phorbol ester (4β-12-O-tetradecanoyl phorbol-13-acetate, TPA) in water and methanol. Plasma irradiation on the solution sample was conducted for 15 min. In aqueous solution, only 16% of TPA was degraded and complete degradation of J. PEs was observed. On the contrary, complete degradation of both TPA and J. PEs in methanol was achieved by the same plasma irradiation condition. Hydroxyl radical (.OH) generated by plasma irradiation of the solution is expected as the main radical inducing the degradation of PEs.

Neural and psychological mechanisms underlying compulsive drug seeking habits and drug memories--indications for novel treatments of addiction.

Science.gov (United States)

Everitt, Barry J

2014-07-01

This review discusses the evidence for the hypothesis that the development of drug addiction can be understood in terms of interactions between Pavlovian and instrumental learning and memory mechanisms in the brain that underlie the seeking and taking of drugs. It is argued that these behaviours initially are goal-directed, but increasingly become elicited as stimulus-response habits by drug-associated conditioned stimuli that are established by Pavlovian conditioning. It is further argued that compulsive drug use emerges as the result of a loss of prefrontal cortical inhibitory control over drug seeking habits. Data are reviewed that indicate these transitions from use to abuse to addiction depend upon shifts from ventral to dorsal striatal control over behaviour, mediated in part by serial connectivity between the striatum and midbrain dopamine systems. Only some individuals lose control over their drug use, and the importance of behavioural impulsivity as a vulnerability trait predicting stimulant abuse and addiction in animals and humans, together with consideration of an emerging neuroendophenotype for addiction are discussed. Finally, the potential for developing treatments for addiction is considered in light of the neuropsychological advances that are reviewed, including the possibility of targeting drug memory reconsolidation and extinction to reduce Pavlovian influences on drug seeking as a means of promoting abstinence and preventing relapse. © 2014 The Author.

Help-seeking for mental disorders is a complex process, which includes different temporary stages, and in which the motivational variables play an especially relevant role. However, there is a lack of instruments to evaluate in depth both the temporary and motivational variables involved in the help-seeking process. This study aims to analyse in detail these two sets of variables, using a specific instrument designed for the purpose, to gain a better understanding of the process of treatment seeking. A total of 152 patients seeking treatment in mental health outpatient clinics of the NHS were individually interviewed: 71 had Obsessive-Compulsive Disorder, 21 had Agoraphobia, 18 had Major Depressive Disorder), 20 had Anorexia Nervosa, and 22 had Cocaine Dependence. The patients completed a structured interview assessing the help-seeking process. Disorder severity and quality of life was also assessed. The patients with agoraphobia and with major depression took significantly less time in recognising their mental health symptoms. Similarly, patients with major depression were faster in seeking professional help. Motivational variables were grouped in 3 sets: motivators for seeking treatment, related to the negative impact of symptoms on mood and to loss of control over symptoms; motivators for delaying treatment, related to minimisation of the disorder; and stigma-associated variables. The results support the importance of considering the different motivational variables involved in the several stages of the help-seeking process. The interview designed to that end has shown its usefulness in this endeavour. Copyright © 2017 SEP y SEPB. Publicado por Elsevier España, S.L.U. All rights reserved.

Aldehyde dehydrogenase (E.C. 1.2.1.x) can catalyze detoxification of acetaldehydes. A novel acetaldehyde dehydrogenase (istALDH) from the non-Saccharomyces yeast Issatchenkia terricola strain XJ-2 has been previously characterized. In this work, Lactococcus lactis with the NIsin Controlled Expression (NICE) System was applied to express the aldehyde dehydrogenase gene (istALDH) in order to catalyze oxidation of acetaldehyde at low pH. A recombinant L. lactis NZ3900 was obtained and applied for the detoxification of acetaldehyde as whole-cell biocatalysts. The activity of IstALDH in L. lactis NZ3900 (pNZ8148-istALDH) reached 36.4 U mL -1 when the recombinant cells were induced with 50 ng mL -1 nisin at 20 °C for 2 h. The IstALDH activity of recombinant L. lactis cells showed higher stability at 37 °C and pH 4.0 compared with the crude enzyme. L. lactis NZ3900 (pNZ8148-istALDH) could convert acetaldehyde at pH 2.0 while the crude enzyme could not. Moreover, the resting cells of L. lactis NZ3900 (pNZ8148-istALDH) showed a 2.5-fold higher activity and better stability in catalyzing oxidation of acetaldehyde at pH 2.0 compared with that of Escherichia coli expressing the IstALDH. Taken together, the L. lactis cells expressing recombinant IstALDH are potential whole-cell biocatalysts that can be applied in the detoxification of aldehydes.

Lapse and relapse following inpatient treatment of opiate dependence.

LENUS (Irish Health Repository)

Smyth, B P

2010-06-01

We conducted a prospective follow-up study of consecutive opiate dependent patients admitted to a residential addiction treatment service for detoxification. We measured the rate of relapse following discharge, and sought to identify factors that were associated with early relapse (i.e., a return to daily opiate use). Follow-up interviews were conducted with 109 patients, of whom, 99 (91%) reported a relapse. The initial relapse occurred within one week in 64 (59%) cases. Multivariate survival analysis revealed that earlier relapse was significantly predicted by younger age, greater heroin use prior to treatment, history of injecting, and a failure to enter aftercare. Unexpectedly, those who were in a relationship with an opiate user had significantly delayed relapse. Those who completed the entire six-week inpatient treatment programme also had a significantly delayed relapse. In order to reduce relapse and the associated increased risk of fatal overdose, services providing residential opiate detoxification should prepare people for admission, strive to retain them in treatment for the full admission period and actively support their entry into planned aftercare in order to improve outcome.

The purpose of this study was to measure the effects of social and economic variables, disease-related variables, and child gender on the decisions of parents in Kerala, India, to seek care for their children and on their choice of providers in the allopathic vs. the alternative system. A case-control analysis was done using data from the Kerala section of the 1996 Indian National Family Health Survey, a cross-sectional survey of a probability sample of households conducted by trained interviewers with a close-ended questionnaire. Of the 469 children who were eligible for this study because they had at least one common symptom suggestive of acute respiratory illness or diarrhea during the 2 weeks before the interview, 78 (17%) did not receive medical care, while the remaining 391 (83%) received medical care. Of the 391 children who received medical care, 342 (88%) received allopathic medical care, and 48 (12%) received alternative medical care. In multivariable analyses, parents chose not to seek medical care for their children significantly more often when the illness was mild, the child had a specific diagnosis, the mother had previously made fewer antenatal visits, and the family had a higher economic status. When parents sought medical care for their children, care was sought significantly more often in the alternative provider system when the child was a boy, the family lived in a rural area, and the family had a lower social class. We conclude that, in Kerala, disease severity and economic status predict whether children with acute respiratory infection or diarrhea are taken to medical providers. In contrast, most studies of this issue carried out in other populations have identified economic status as the primary predictor of medical system utilization. Also in Kerala, the gender of the child did not influence whether or not the child was taken for treatment but did influence whether care was sought in the alternative or the allopathic system.

In view of compliance with increasingly stringent environmental legislation, an eco-friendly treatment technology of industrial dyes and effluents is a major environmental challenge in the color industry. In present study, a promising and eco-friendly entrapment approach was adopted to immobilize purified manganese peroxidase (MnP) produced from an indigenous strain of Ganoderma lucidum IBL-05 on Ca-alginate beads. The immobilized MnP was subsequently used for enhanced decolorization and detoxification of textile reactive dyes). MnP isolated from solid-state culture of G. lucidum IBL-05, presented highest immobilization yield (83.9 %) using alginate beads prepared at optimized conditions of 4 % (w/v) sodium alginate, 2 % (w/v) Calcium chloride (CaCl2) and 0.5 mg/ml enzyme concentration. Immobilization of MnP enhanced optimum temperature but caused acidic shift in optimum pH of the enzyme. The immobilized MnP showed optimum activity at pH 4.0 and 60 °C as compared to pH 5.0 and 35 °C for free enzyme. The kinetic parameters K(m) and V(max) of MnP were significantly improved by immobilization. The enhanced catalytic potential of immobilized MnP led to 87.5 %, 82.1 %, 89.4 %, 95.7 % and 83 % decolorization of Sandal-fix Red C4BLN, Sandal-fix Turq Blue GWF, Sandal-fix Foron Blue E2BLN, Sandal-fix Black CKF and Sandal-fix Golden Yellow CRL dyes, respectively. The insolubilized MnP was reusable for 7 repeated cycles in dye color removal. Furthermore, immobilized MnP also caused a significant reduction in biochemical oxygen demand (BOD) (94.61-95.47 %), chemical oxygen demand (COD) (91.18-94.85 %), and total organic carbon (TOC) (89.58-95 %) of aqueous dye solutions. G. lucidum MnP was immobilized in Ca-alginate beads by entrapment method to improve its practical effectiveness. Ca-alginate bound MnP was catalytically more vigorous, thermo-stable, reusable and worked over wider ranges of pH and temperature as compared to its free counterpart. Results of cytotoxicity like

The relationship between hepatitis B (HBV) infection in infertile couples seeking in vitro fertilization (IVF) treatment and infertility causes is unknown. A total of 831 infertile couples attending our unit seeking IVF during January to December 2015 were recruited. HBV infection was found in 6.3% and 7.3% of female and male partners, respectively, and infection in one or both partners was associated with less primary infertility (44.2% vs 55.1%, P=.038). Infected female partners had increased tubal (69.2% vs 43.2%, Pinfertility, while infected male partners were associated with increased tubal (62.3% vs 43.4%, P=.004) causes and reduced endometriosis (62.3% vs 73.9%, P=.050). Our results suggest HBV infection in either partner was associated with tubal infertility. HBV infection in either partner probably increases the risk of pelvic infection in female partner through impaired immune response to sexually transmitted infections, with consequent tubal damage and infertility. © 2017 John Wiley & Sons A/S.

Individuals with low socioeconomic status (SES) and members of racial/ethnic minority groups often experience profound disparities in mental health and physical well-being. Mindfulness-based interventions show promise for improving mood and health behaviors in higher-SES and non-Latino White populations. However, research is needed to explore what types of adaptations, if any, are needed to best support underserved populations. This study used qualitative methods to gain information about a) perceptions of mindfulness, b) experiences with meditation, c) barriers to practicing mindfulness, and d) recommendations for tailoring mindfulness-based interventions in a low-income, primarily African American treatment-seeking sample. Eight focus groups were conducted with 32 adults (16 men and 16 women) currently receiving services at a community mental health center. Most participants (91%) were African American. Focus group data were transcribed and analyzed using NVivo 10. A team of coders reviewed the transcripts to identify salient themes. Relevant themes included beliefs that mindfulness practice might improve mental health (e.g., managing stress and anger more effectively) and physical health (e.g., improving sleep and chronic pain, promoting healthier behaviors). Participants also discussed ways in which mindfulness might be consistent with, and even enhance, their religious and spiritual practices. Results could be helpful in tailoring mindfulness-based treatments to optimize feasibility and effectiveness for low-SES adults receiving mental health services.

Students with disabilities are a growing population on college campuses and have unique challenges that put them at risk for early departure, creating complexity in efforts to address their personal and academic needs. The purpose was to explore academic and other sources of distress among college students with disabilities to identify possible areas where enhanced supports might benefit this population. Research Method and Design: Researchers analyzed cross-sectional data from the Center for Collegiate Mental Health to compare subsamples of students with (n = 1,774) and without disabilities (n = 1,774) on presenting concerns, and to determine significant predictors of academic distress among students with disabilities. Results indicated that students with disabilities have many similar treatment concerns with their peers, but showed greater concerns in depression and self-harm; academic performance; anxiety and obsessions/compulsions; and fewer concerns in relationship problems. Significant predictors of academic distress for students with disabilities included attention deficit-hyperactivity disorder (ADHD), depression and self-harm, trauma or victimization, stress and academic performance, and social support from family and peers. These results suggest the importance of several factors in understanding the presenting concerns of treatment-seeking students with disabilities and mitigating academic distress for this population. Additional areas for research are presented. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Although posttraumatic stress disorder (PTSD) and other psychiatric symptoms are well-established risk factors for suicidal ideation among returning veterans, less attention has been paid to whether the stress of reintegrating into civilian society contributes to suicidal ideation. Utilizing a sample of 232 returning veterans (95% male, mean age = 33.63 years) seeking PTSD treatment, this study tested whether reintegration difficulties contribute to suicidal ideation over and above the influence of PTSD symptoms, depression symptoms, and potential substance misuse. Logistic regressions indicated that reintegration stress had a unique effect on suicidal ideation over and above PTSD and depression symptoms. Reintegration stress interacted with substance misuse to predict suicidal ideation, such that the effect of reintegration stress on suicidal ideation was much larger for those with potential substance misuse. Exploratory analyses also examined which types of reintegration difficulties were associated with suicidal ideation, and found that difficulty maintaining military friendships, difficulty getting along with relatives, difficulty feeling like you belong in civilian society, and difficulty finding meaning/purpose in life were all significantly associated with suicidal ideation, beyond the effects of psychiatric symptoms and potential substance misuse. Findings highlight the importance of addressing reintegration stress for the prevention of suicide among returning veterans. Implications for treatment are discussed. © Published 2015.

Pornography consumption is highly prevalent, particularly among young adult males. For some individuals, problematic pornography use (PPU) is a reason for seeking treatment. Despite the pervasiveness of pornography, PPU appears under-investigated, including with respect to the underlying neural mechanisms. Using functional magnetic resonance imaging (fMRI), we examined ventral striatal responses to erotic and monetary stimuli, disentangling cue-related 'wanting' from reward-related 'liking' among 28 heterosexual males seeking treatment for PPU and 24 heterosexual males without PPU. Subjects engaged in an incentive delay task in the scanner, in which they received erotic or monetary rewards preceded by predictive cues. Blood-oxygen-level-dependent responses to erotic and monetary cues were analyzed and examined with respect to self-reported data on sexual activity collected over the 2 preceding months. Men with and without PPU differed in their striatal responses to cues predicting erotic pictures but not in their responses to erotic pictures. PPU subjects when compared with control subjects showed increased activation of ventral striatum specifically for cues predicting erotic pictures but not for cues predicting monetary gains. Relative sensitivity to cues predicting erotic pictures vs monetary gains was significantly related to the increased behavioral motivation to view erotic images (suggestive of higher 'wanting'), severity of PPU, amount of pornography use per week, and number of weekly masturbations. Our findings suggest that, similar to what is observed in substance and gambling addictions, the neural and behavioral mechanisms associated with the anticipatory processing of cues specifically predicting erotic rewards relate importantly to clinically relevant features of PPU. These findings suggest that PPU may represent a behavioral addiction and that interventions helpful in targeting behavioral and substance addictions warrant consideration for adaptation

This study asked, What are the psychological characteristics of Vietnam combat veterans who claim Agent Orange exposure when compared with combat-experienced cohorts who do not report such contamination The question was researched among 153 heroin addicts, polydrug abusers, and chronic alcoholics who were seeking treatment: 58 reported moderate to high defoliant exposure while in combat; 95 reported minimal to no exposure while in Vietnam. The null hypothesis was accepted for measures of childhood and present family social climate, premilitary backgrounds, reasons for seeking treatment, patterns and types of illicit drug and alcohol use, interpersonal problems, intellectual functioning, and short-term memory. The null hypothesis was rejected for personality differences, however, those who self-reported high Agent Orange exposure scored significantly higher on MMPI scales F, Hypochondriasis, Depression, Paranoia, Psychasthenia, Schizophrenia, Mania, and Social interoversion. The results suggest that clinicians carefully assess attributional processing of those who report traumatic experience.

This study focuses on differential molecular mechanisms of antioxidant and detoxification systems in rice plants under two different types of photodynamic stress imposed by porphyrin deregulators, 5-aminolevulinic acid (ALA) and oxyfluorfen (OF). The ALA-treated plants with white necrosis exhibited a greater decrease in photochemical quantum efficiency, Fv/Fm, as well as a greater increase in activity of superoxide dismutase, compared to the OF-treated plants. By contrast, the brown necrosis in OF-treated plants resulted in not only more widely dispersed H2O2 production and greater increases in H2O2-decomposing enzymes, catalase and peroxidase, but also lower ascorbate redox state. In addition, ALA- and OF-treated plants markedly up-regulated transcript levels of genes involved in detoxification processes including transport and movement, cellular homeostasis, and xenobiotic conjugation, with prominent up-regulation of serine/threonine kinase and chaperone only in ALA-treated plants. Our results demonstrate that different photodynamic stress imposed by ALA and OF developed differential actions of antioxidant enzymes and detoxification. Particularly, detoxification system may play potential roles in plant protection against photodynamic stress imposed by porphyrin deregulators, thereby contributing to alleviation of photodynamic damage.

Dempster, Robert; Wildman, Beth; Keating, Adam

2013-01-01

The present study examined the relationship between stigma and parental help-seeking after controlling for demographics, child behavior, and barriers to treatment. One hundred fifteen parents of children ages 4 to 8 years were surveyed during well-child visits in a rural pediatric primary care practice. Parental perceptions of stigma toward parents and children were both assessed. Parents believe that children are more likely to be stigmatized by the public and personally impacted by stigma. In linear regression analyses, parents rated themselves as more likely to attend parenting classes with lower levels of self-stigma and greater levels of personal impact of stigma. Stigma toward the child was not associated with help-seeking. Child behavior moderated the relationship between stigma and parental help-seeking. When referring parents to treatment, providers should address potential stigma concerns. Future research should assess both the impact of the stigma of attending treatment and the stigma of having a child with behavior problems.

Highlights: {yields} The Alcaligenes faecalis strain SAG{sub 5} decolorizes 72.6 {+-} 0.56% of melanoidins. {yields} The decolorization was achieved at pH 7.5 and temperature 37 {sup o}C on 5th day. {yields} The distillery effluent after biological treatment is environmentally safe. - Abstract: Distillery effluent retains very dark brown color even after anaerobic treatment due to presence of various water soluble, recalcitrant and coloring compounds mainly melanoidins. In laboratory conditions, melanoidin decolorizing bacteria was isolated and optimized the cultural conditions at various incubation temperatures, pH, carbon sources, nitrogen sources and combined effect of both carbon and nitrogen sources. The optimum decolorization (72.6 {+-} 0.56%) of melanoidins was achieved at pH 7.5 and temperature 37 {sup o}C on 5th day of cultivation. The toxicity evaluation with mung bean (Vigna radiata) revealed that the raw distillery effluent was environmentally highly toxic as compared to biologically treated distillery effluent, which indicated that the effluent after bacterial treatment is environmentally safe. This proves to be novel biological treatment technique for biodegradation and detoxification of melanoidin from distillery effluent using the bacterial strain SAG{sub 5}.

Blood is a site of physiological transport for a great variety of molecules, including xenobiotics. Blood cells in aquatic vertebrates, such as fish, are directly exposed to aquatic pollution. P-gp are ubiquitous "membrane detoxification proteins" implicated in the cellular efflux of various xenobiotics, such as polycyclic aromatic hydrocarbons (PAHs), which may be pollutants. The existence of this P-gp detoxification system inducible by benzo [a] pyrene (BaP), a highly cytotoxic PAH, was investigated in the nucleated erythrocytes of brown trout. Western blot analysis showed the expression of a 140-kDa P-gp in trout erythrocytes. Primary cultures of erythrocytes exposed to increasing concentrations of BaP showed no evidence of cell toxicity. Yet, in the same BaP-treated erythrocytes, P-gp expression increased significantly in a dose-dependent manner. Brown trout P-gp erythrocytes act as membrane defence mechanism against the pollutant, a property that can be exploited for future biomarker development to monitor water quality.

The aim of this study was to systematically review and meta-analyze the prevalence of comorbid personality disorders among treatment-seeking problem gamblers. Almost one half (47.9%) of problem gamblers displayed comorbid personality disorders. They were most likely to display Cluster B disorders (17.6%), with smaller proportions reporting Cluster C disorders (12.6%) and Cluster A disorders (6.1%). The most prevalent personality disorders were narcissistic (16.6%), antisocial (14.0%), avoidant (13.4%), obsessive-compulsive (13.4%), and borderline (13.1%) personality disorders. Sensitivity analyses suggested that these prevalence estimates were robust to the inclusion of clinical trials and self-selected samples. Although there was significant variability in reported rates, subgroup analyses revealed no significant differences in estimates of antisocial personality disorder according to problem gambling severity, measure of comorbidity employed, and study jurisdiction. The findings highlight the need for gambling treatment services to conduct routine screening and assessment of co-occurring personality disorders and to provide treatment approaches that adequately address these comorbid conditions.

Full Text Available Bacteria are able to communicate with each other and sense their environment in a population density dependent mechanism known as quorum sensing (QS. N-acyl-homoserine lactones (AHLs are the QS signalling compounds of Gram-negative bacteria which are frequent colonizers of rhizospheres. While cross-kingdom signalling and AHL-dependent gene expression in plants has been confirmed, the responses of enzyme activities in the eukaryotic host upon AHLs are unknown. Since AHL are thought to be used as so-called plant boosters or strengthening agents, which might change their resistance towards radiation and/or xenobiotic stress, we have examined the plants’ pigment status and their antioxidative and detoxifying capacities upon AHL treatment. Because the yield of a crop plant should not be negatively influenced, we have also checked for growth and root parameters.We investigated the influence of three different AHLs, namely N-hexanoyl- (C6-HSL, N-octanoyl- (C8-HSL and N-decanoyl- homoserine lactone (C10-HSL on two agricultural crop plants. The AHL-effects on Hordeum vulgare (L. as an example of a monocotyledonous crop and on the tropical leguminous crop plant Pachyrhizus erosus (L were compared. While plant growth and pigment contents in both plants showed only small responses to the applied AHLs, AHL treatment triggered tissue- and compound-specific changes in the activity of important detoxification enzymes. The activity of dehydroascorbate reductase (DHAR in barley shoots after C10-HSL treatment for instance increased up to 384% of control plant levels, whereas superoxide dismutase (SOD activity in barley roots was decreased down to 23% of control levels upon C6-HSL treatment. Other detoxification enzymes reacted similarly within this range, with interesting clusters of positive or negative answers towards AHL treatment. In general the changes on the enzyme level were more severe in barley than in yam bean which might be due to the different

Pyrolysis is a sustainable pathway to transform renewable biomasses into both biofuels and advanced carbonaceous materials (i.e. pyrochar) which can be used as adsorbent of furan compounds. In particular, the aim of this study was to: i) evaluate the effect of vibro-ball milling on physical characteristics of pyrochar and its consequent performance on solely detoxification of a synthetic medium, containing furans and soluble sugars; ii) study the simultaneous detoxification and bioethanol fermentation, by adding activated pyrochar into fermentation medium. Results demonstrated that, compared to untreated pyrochar, the use of milled pyrochar increased by 52% furfural removal from the synthetic medium. Furfural removal rate was also increased (adsorption kinetic constant increased from 0.015 min -1 up to 0.215 min -1 ), at a pyrochar loading of 40 g L -1 . Although, the simultaneous addition of pyrochar into the fermentation medium did not improve the bioethanol yield of the synthetic medium, it has significantly increased the bioethanol production rate.

To examine whether detoxifying patients with medication-overuse headache can reduce long-term medication costs. Direct costs of medications in medication-overuse headache have been reported to be very high but have never been calculated on the basis of exact register data. Long-term economic savings obtained by detoxification have never been investigated. We conducted a registry-based observational retrospective follow-up study on 336 medication-overuse headache patients treated and discharged from the Danish Headache Center over a 2-year period. By means of the Danish Register of Medicinal Product Statistics, we collected information on the costs and use of prescription-only medication 1 year before admission and 1 year after discharge from Danish Headache Center. The average medication costs per patient per year decreased with 24%, from US$971 before treatment to US$737 after (P = .001), and the average medication use decreased with 14.4% (P = .02). Savings were most pronounced for patients overusing triptans. In this group, the average medication costs per patient per year decreased with 43% (P headache at a tertiary headache center has a long-lasting effect on the medication costs and use, in particular among patients overusing triptans. The results may not be generalizable to all countries and may be sensitive to the costs of triptans. © 2012 American Headache Society.
